1 Sat Feb 9 14:54:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Allow zero length channel messages inside the Channel Message
4 Payload. Affected file lib/silccore/silcchannel.c.
6 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
9 * Removed lib/silcclient/README and created HTML file
10 lib/silcclient/silcclient_using.html, which is now included
11 as part of Toolkit documentation.
13 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
15 * Fixed CUMODE_CHANGE notify handling to change the mode of
16 correct client. Affected file lib/silcclient/client_notify.c.
18 * Make silc_rng_alloc fail if it cannot allocate the sha1
19 hash algorithm. Affected file lib/silccrypt/silcrng.c.
21 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
23 * Fixed the file transfer's key agreement payload to include
24 zero port also if the hostname is NULL because it could not
27 Call file transfer monitor callback now also if error occurs
28 during key agreement protocol.
30 Changed the silc_client_file_send interface to return the
31 SilcClientFileError instead of session id. The session ID
32 is returned into pointer provided as argument.
34 Check that the file exists locally before sending the
35 file transfer request at all.
37 Affected file lib/silcclient/client_ftp.c, silcapi.h.
39 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
40 error than can occur while key agreement protocol. Affected
41 file lib/silcclient/silcapi.h.

44 is changed and +k mode is set in the channel. Affected file
45 irssi/src/silc/core/silc-channels.c.
47 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
48 SILC_LOG_WARNING to give out Warning and not Error. Affected
49 file lib/silcutil/silclog.c.
51 * Fixed the channel message payload decryption in the function
52 silc_channel_message_payload_decrypt to not modify the original
53 buffer before it is verified that the message decrypted
54 correctly. Otherwise, next time it is called with correct
55 channel key it won't encrypt since the payload is corrupted.
56 Affected file lib/silccore/silcchannel.c.
58 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Do not constantly resize the window. A fix patch by cras.
61 Affected file irssi/src/fe-text/screen.c.

65 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
66 Affected file lib/silcutil/silcnet.c.
68 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
70 * Fixed a bug in hash table internal routine for traversing
71 the table with foreach callback. The current entry may
72 become invalid in the callback but it was referenced after
73 the callback returned.
75 Do not allow auto rehashing of hash table during the
76 silc_hash_table_foreach operation, for same reasons as it is
77 not allowed for SilcHashTableList. Affected files are
78 lib/silcutil/silchashtable.[ch].
80 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
82 * Defined DLLAPI into silcincludes.h and silcwin32.h for
83 Win32 DLL. extern's in header files are now declared with
86 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
88 * Fixed private message handling. It used some old code that
89 caused the client to crash. Affecte file is
90 lib/silcclient/client_prvmsg.c.
92 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Added function silc_client_add_channel,
95 silc_client_replace_channel_id, and removed functions
96 silc_client_new_channel_id and silc_idlist_get_channel_by_id
99 * Added cross reference of the joined channels to the
100 SilcClientEntry, and changed the SilcChannelEntry's
101 users list to SilcHashTable. The affected files are
102 lib/silcclient/idlist.[ch].
104 * Fixed a bug in hash table tarversing. While the hash table
105 is traversed with SilcHashTableList the table must not be
106 rehashed. It is now guaranteed that auto rehashable tables
107 are not rehashed while tarversing the list. Also defined that
108 silc_hash_table_rehash must not be called while tarversing
109 the table. Added function silc_hash_table_list_reset that must
110 be called after the tarversing is over. The affected files are
111 lib/silcutil/silchashtable.[ch].
113 * Changed all hash table traversing to call the new
114 silc_hash_table_list_reset in server and in client library.
116 * Added function silc_client_on_channel to return the
117 SilcChannelUser entry if the specified client entry is joined
118 on the specified channel. This is exported to application as
119 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
121 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
123 * Fixed founder regaining problem with JOIN command on normal
124 server. The notify for mode change must be sent always and
125 not only if !cmd->pending. Affected file silcd/command.c.
127 * Fixed the WHOWAS command's reply sending to support the
128 lists correctly. Affected file silcd/command.c.
130 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
132 * When sending JOIN command to router for processing the
133 sender's old command identifier was not saved back to the
134 sender's command context, fixed now. The affected file is
137 * Create the key in JOIN command of the router did not return
138 the channel key, added check for this. Affected file is
141 * Fixed a channel ID update bug in JOIN command reply. Do
142 not directly upgrade the ID but call the function
143 silc_idlist_replace_channel_id if the ID was changed.
144 Affected file silcd/command_reply.c.
146 * Fixed memory leaks from command calling if it would fail.
147 Affected file silcd/command.c.
149 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
151 * Applied patches from cras:
153 Memory leak fixes around libaries, irssi window resize fix,
154 new silclist.h and silcdlist.h, all extern inline changed to
157 * Removed dotconf from lib/dotconf, not needed anymore.
159 * Removed TRQ from lib/trq, not needed anymore.
161 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
162 with server connections. Later this will be configurable
163 in config file after new config file is done. Affected file
166 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
168 * Fixed a crash in server related to channel announcements.
169 Affected file silcd/server.c.
171 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
173 * Fixed memory leaks in silc_server_create_new_channel*
174 functions. Affected file silcd/server.c.
176 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
177 which ID was changed. This way the router will send the
178 user list for the channel again, and server won't be in
179 desync in some rare circumstances. Affected file is
180 silcd/packet_receive.c.
182 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Check for NULL socket pointer in the function
185 silc_server_packet_send_to_channel_real. Affected file
188 * Fixed the BAN notify handling to correctly remove ban
189 list. Affected file silcd/packet_receive.c.
191 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
193 * Fixed some header addition to Toolkit distribution in
194 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
196 * Added lib/silcclient/client_ops_example.h as an template
197 file for application programmers to quickly start using
198 the SilcClientOperation functions in their application.
199 Updated the lib/silcclient/README as well to tell about this
200 nice file made available.
202 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
204 * Call silc_server_remove_from_channels when removing client
205 entry when NO_SUCH_CLIENT_ID was received. Affected file
206 is silcd/command_reply.c.
208 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
210 * Added server & router operator statistics updating. Affected
211 file silcd/packet_receive.c and silcd/command.c.
213 * Fixed the SERVER_SIGNOFF notify handling on normal server
214 not to save the history information for clients. Same was
215 fixed earlier in remove_clients_by_server function, but not
216 here. Affected file silcd/packet_receive.c.
218 * Raised the default connection-retry count from 4 to 7 in
219 server. Affected file silcd/server.h.
221 * Cancel any possible reconnect timeouts when we start the
222 key exchange. Affected file silcd/server.c.
224 * Do not reconnect on connection failure when SCONNECT was
225 given. Affected files silcd/server.[ch].
227 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
229 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
231 * Fixed the NICK command to always give the unformatted
232 nickname to the one giving the NICK command. If unformatted
233 nickname is cached already it will be formatted and the
234 local entry will always get the unformatted nickname.
235 Affected file lib/silcclient/idlist.c.
237 * Fixed some double frees from client library commands.
238 Affected file is lib/silcclient/command.c.
240 * Fixed CUMODE command in server to assure that no one can
241 change founder's mode than the founder itself, there was a
242 little bug. Affected file silcd/command.c.
244 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
246 * Removed the SilcClientCommandDestructor from the client
247 libary, it is not needed anymore. Affected files are
248 lib/silcclient/silcapi.h, command[_reply].[ch],
249 client_notify, idlist.c.
251 * Fixed GETKEY command to first resolve client, and then
252 resolve the server only if the client was not found, instead
253 of resolving both at the same time. Affected file is
254 lib/silcclient/command.c.
256 * Added silc_client_start_key_exchange_cb and lookup the
257 remote hostname and IP address before starting the key
258 exchange with server. The affected file is
259 lib/silcclient/client.c.
261 * The server's public key is now saved using the IP address
262 of the server and not the servername for the filename.
263 The hostname public key filename is checked as an fall back
264 method if the IP address based filename is not found.
266 Fixed the GETKEY command to save the fetched server key
269 Print the remote server's hostname now when new key is
270 received during connection process. Affected file is
271 irssi/src/silc/core/client_ops.c.
273 * Return always our own public key to the client if it asks
274 for it with GETKEY command. Affected file silcd/command.c.
276 * Removed the use_auto_addr variable from default config
277 file since it was in wrong section. Affected file is
280 * Fixed TOPIC_CHANGE notification to not route it when it
281 was sent using silc_server_send_notify_to_channel function.
282 Affected file silcd/command.c.
284 * Fixed silc_server_send_notify_kicked to send the kicker's
285 Client ID also, it was missing. Affected files are
286 silcd/command.c, silcd/packet_send.[ch].
288 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Do not save client history information in SERVER_SIGNOFF.
291 Fixes the bug in normal server that it does not detect
292 the client becoming valid after the server becomes back
293 online. Affected file silcd/server_util.c.
295 * Added `sock_error' field into the SilcSocketConnection
296 context. When error occurs during socket operation (read
297 or write) the error is saved. Added also new function
298 silc_socket_get_error to return human readable socket error
299 message. Affected files are lib/silcutil/silcsockconn.[ch],
300 lib/silcutil/unix/silcunixsockconn.c, and
301 lib/silcutil/win32/silcwin32sockconn.c.
303 * The server now prints the socket error message in the
304 signoff for client. Affected file silcd/server.c.
306 * Fixed the `created' channel information sending from router
307 to server in JOIN command. Checks now whether the channel
308 really was created or not and set it according that.
310 Fixed the JOIN command to use the client entry's current
311 ID during the joining procedure instead of the one it sent
312 in the command (it is checked though), since it can change
313 between the packet processing and command processing, and
314 would just case unnecessary pain in the client end. Affected
315 file silcd/command.c.
317 * Fixed a channel key payload sending to use correct channel
318 ID when the server was forced to change the channel's ID by
319 router. Router sent the key payload with the old Channel ID.
320 Affected file silcd/packet_receive.c.
322 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Call silc_server_save_channel_key only if the key payload
325 was provided in the JOIN command's command reply. Affected
326 file silcd/command_reply.c.
328 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
330 * Fixed silc_mp_sizeinbase to return the value correctly with
331 MPI. Affected file lib/silcmath/mp_mpi.c.
333 * Fixed the stop_server signal to correctly stop the scheduler
334 and gracefully stop the server when SIGTERM or SIGINT signals
335 are received. Affected file silcd/silcd.c.
337 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
339 * Simple handling of TERM and HUP signals. Also added some log
340 flushing call around. Affected file is
343 * Fixed small bugs in silclog.c. Now buffering output will take
344 effect after 10 seconds since startup: This will ensure that
345 no important startup messages are lost. Also output redirection
346 will preserve original format ([Date] [Type] message).
347 Affected file is lib/silcutil/silclog.c.
349 * Added two options to the config file, in the logging section:
350 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
351 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
353 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
355 * Do not print the warning about log files not being initialized
356 more than once to avoid excess logging. Affected file is
357 lib/silcutil/silclog.c.
359 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
360 the SIM copying in make install in Makefile.am.pre.
362 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
364 * Rewritten silclog APIs. Globally interesting changes follows:
365 silc_log_set_files() changed to silc_log_set_file().
366 silc_log_set_callbacks() changed to silc_log_set_callback().
367 ROBOdoc documented silclog header file.
368 SilcLogCb now returns bool to wether inihibit the default
369 handler or not (to keep the old behaviour return always TRUE).
370 The new APIs should also fix the problem of the
371 silcd_error.log file that was written in the current directory.
374 Log files streams will remain opened after silc_log_set_file()
375 call, means less CPU usage notably on high traffic servers.
376 File streams are now full buffered, and flushed to the disk
377 every 5 minutes, lesses HD activity and CPU usage.
378 Messages can be redirected, allowing admins to configure
379 one single logfile for all server messages.
380 the silc_log_quick global variable to activate fast-logging.
381 Affected files lib/silcutil/silclog.[ch]
383 * Changed some code to conform new silclog APIs. Affected
384 files are doc/example_silcd.conf.in, silcd/server.c
385 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
388 * Fixed a memory leak that could occur in some situations.
389 Affected file silcd/serverconfig.c.
391 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
393 * Added the silc_client_del_client to remove the client from
394 all channels as well. Affected file lib/silcclient/idlist.c.
396 * Fixed the client library to correctly remove the client
397 from all channels when the client entry is being destroyed.
398 Affected file lib/silcclient/client_notify.c, command.c.
400 * Added auto-nicking support to the client library. If the
401 applicatio now sets client->nickname it will be sent to the
402 server after connecting by the library. This way for example
403 SILCNICK (or IRCNICK) environment variables will have effect
404 and always change the nickname automatically to whatever
405 it is wanted. Affected file lib/silcclient/client.[ch].
407 * Renamed silc_server_command_bad_chars to the
408 silc_server_name_bad_chars and moved it to the
409 silcd/server_util.[ch]. Added also new function
410 silc_server_name_modify_bad to return nickname that
411 includes bad characters as new nickname without those
412 bad characters. This check and modify is now used in
413 silc_server_new_client when the username is initially set
414 as nickname, so it must be checked to be valid nickname.
415 Affected file silcd/packet_receive.c.
417 * The nickname length is now taken from the packet for real
418 and not trusted to strlen() since it clearly can return
419 wrong length for nickname including bad characters. This
420 also applies to channel names. Affected file silcd/command.c.
422 * Removed the lib/silcsilm/modules directory. Modules are now
423 compiled into the lib/silcsim. Fixed the copying of the
424 modules to follow symbolic links in Makefile.am.pre.
426 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
428 * Fixed silc_string_regexify list creation. Fixes bugs with
429 BAN and INVITE commands in server. The affected file is
430 lib/silcutil/unix/silcunixutil.c.
432 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
434 * Removed the command destructor entirely from the server's
435 command and command reply routines. It is not needed, and
436 its usage was buggy and caused crashes. Affected files are
437 silcd/command[_reply].[ch].
439 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
441 * Cancel protocol and NULL sock->protocol if timeout
442 occurred during protocol. Affected file silcd/server.c.
444 * Cancel protocol timeouts always before calling the final
445 callback, to assure that after final callback is called
446 no other state will be called for the protocol anymore.
447 Affected file silcd/protocol.c.
449 * Print error log if incoming connection configuration could
450 not be found. Affected file silcd/server.c.
452 * Fixed JOIN command to correctly save the founder mode
453 to the client on normal SILC server, when the channel
454 was created by the router. Affected file silcd/command.c.
456 * Fixed LIST command (hopefully) to send correct reply
457 packets. Affected file silcd/command.c.
459 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
461 * The silc_packet_receive_process now returns FALSE if the
462 read data was invalid packet, and TRUE if it was ok.
464 The server now checks that if unauthenticated connection
465 sends data and its processing fails the server will close
466 the connection since it could be a malicious flooder.
468 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
470 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Make sure the warning about error opening a log file is
473 printed only once and not everytime it fails (produces
474 too much useless log). Affected file lib/silcutil/silclog.c.
476 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
478 * Made the silc_server_daemonise() function more readable.
479 Affected file silcd/server.c.
481 * Pid file is now optional, the user may comment it out from
482 the config file. Removed define SILC_SERVER_PID_FILE, we
483 don't need a default any longer. Affected file
484 configure.in.pre, lib/Makefile.am.pre.
486 * Make some use of the pid file. The server now dies at startup
487 if it detects a valid pid file on his path. The server would
488 die anyway in this circumstance, because of the bind() failure.
489 Affected file silcd/silcd.c.
491 * No longer compiling lib/dotconf.
493 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Fixed JOIN command parsing not to crash. Affected file
496 lib/silcclient/command.c.
498 * Fied the NICK_CHANGE notify to add the new client entry
499 even it is resolved. This removes an <[unknown]> nick
500 thingy bug in the client. Affected file is
501 lib/silcclient/client_notify.c.
503 * Do not try to allocate 0 bytes (efence does not like it)
504 in lib/silccore/silccomand.c when encoding payload.
506 * Do not take IRCNICK as nickname in Irssi SILC client since
507 it is not possible to set nickname before hand connecting
508 the server (TODO has an entry about adding auto-nicking
511 * Changed the silc_server_command_pending to check whether
512 there already exists an pending entry with the specified
513 command, command identifier and pending callback. This is
514 to fix IDENTIFY and WHOIS related crashes that may register
515 multiple pending commands with same identifier. Affected
516 file silcd/command.c.
518 * Fixed the server to reconnect to the router even if it
519 was already reconnecting and EOF was received. This to
520 fix a possibility that the server wouldn't ever try to
521 auto-reconnect to the router. Affected file silcd/server.c.
523 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Fixed the server's password authentication to use the
526 length of the locally saved password, and not the one
527 sent in the packet. Affected file silcd/protocol.c.
529 * Fixed same password authentication problem in the
530 Authentication Payload handling routines in
531 lib/silccore/silcauth.c.
533 * Yet another password authentication problem fixed with
534 channel password handling in silcd/command.c.
536 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
538 * If first character of string in silc_parse_userfqdn is '@'
539 then do not parse it. Affected file is
540 lib/silcutil/silcutil.c.
542 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Fixed minor bug in IDENTIFY command reply sending, which
545 caused various weird problems during JOIN when it was
546 resolving names for users. Affected file silcd/command.c.
548 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Fixed the IDENTIFY command reply sending to chech better valid
551 clients. It was possible to send incomplete list of replies.
552 Affected file silcd/command.c.
554 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Added silc_client_command[s]_[un]register functions now to
557 dynamically register the commands in client library. Removed
558 the static table of commands. This allows the client library
559 to call commands without causing the application to know about
560 what commands library has called.
562 Removed the INFO command reply kludge to detect when the command
563 was called by library. Now library use its own command reply
564 function for INFO command.
566 Added function silc_client_command_call to call a command.
567 Application can use it to call command, not access the structure
570 Now all commands that are sent by the client library (not
571 explicitly sent by application) use own command reply functions.
573 Affected files around lib/silcclient/ and in
574 irssi/src/silc/core/.
576 * Fixed the WHOIS command reply sending to chech better valid
577 clients. It was possible to send incomplete list of replies.
579 Fixed the WHOIS and IDENTIFY to send the request to router
580 if normal server did not do it and did not find any results.
582 Affected file silcd/command.c.
584 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Moved the internal data from SilcClient context into its
587 own file, not accesible to application. Affected files
588 lib/silcclient/client.h and lib/silcclient/client_internal.h,
589 and other files in client library.
591 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
593 * Added doc/examples installation target in Makefile.am.pre.
596 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
598 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
599 commands the found client entry will be removed from the
600 cache, after notifying application about the error. Affected
601 file lib/silcclient/command_reply.c.
603 * Changed the /MSG to check for exact nickname user gave, and
604 not let `nick' match `nick@host' if it is only one found. Now,
605 user must type the exact nickname (like nick@host2) even if
606 there are no more than one same nicks found. This is to avoid
607 a possibility of sending nickname to wrong nickname since
608 `nick' could match `nick@host'. Affected file is
609 irssi/src/core/silc-servers.c.
611 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
613 * Do not print "you are now server operator" or similar when
614 giving /away command. Affected files are
615 irssi/src/silc/core/client_ops.c, silc-servers.h.
617 * Made the silc_server_command_pending_error_check to send
618 the same command reply payload it received back to the
619 original sender of the command. This way all arguments
620 that was received by the server will be received by the
621 client too. Affected file silcd/command.c.
623 * Added the silc_idcache_add to return the created cache entry
624 to a pointer. Affected file lib/silccore/silcidcache.[ch].
626 * Add global clients to expire if they are not on any channel.
627 This is because normal server will never know if they signoff
628 if they are not on any channel. The cache expiry will take
629 case of these entries. This is done by normal servers only.
630 The affected files are silcd/command_reply.c,
631 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
633 * If server receives invalid ID notification for WHOIS or
634 IDENTIFY and the ID exists in the lists, it is removed.
635 Affected file silcd/command_reply.c.
637 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
638 in client then client entry that it matches is searched and
639 the nickname is printed on the screen for user. Affected
640 file irssi/src/silc/core/client_ops.c.
642 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Use cache entry expire time in the LIST command reply to
645 purge old entries from the cache after the LIST command
646 reply has been received. This way we don't have non-existent
647 entries in the cache for too long. Affected file is
648 silcd/command_reply.c.
650 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
652 * If we are normal server, and we've not resolved client info
653 in WHOIS or IDENTIFY from router, and it is global client,
654 we'll check whether it is on some channel. If it is not
655 then we cannot be sure about its validity and will resolve it
656 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
657 file silcd/command.c.
659 * Search channel by name (if possible) rather than by ID
660 in IDENTIFY command's command reply. Affected file is
661 silcd/command_reply.c.
663 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
665 * Distribute to the channel passphrase in CMODE_CHANGE notify.
666 Updated specs and implemented it. Affected file silcd/command.c,
667 silcd/packet_send.c and silcd/packet_receive.c.
669 * Implemented the <founder auth> payload handling in the JOIN
670 command. If provided all conditions for channel joining
671 except requirement to provide correct passphrase can be
672 overrided by the channel founder. Updated the protocol specs.
673 Affected file silcd/command.c.
675 Added support for founder auth in JOIN command in client
676 library. Fixed the parsing of the JOIN command now to support
677 all options as they should be. The affected file is
678 lib/silcclient/command.c.
680 * Optimized the WHOIS and IDENTIFY commands to send the request
681 to router only if it includes nicknames or other names. If
682 they include only IDs then check the local cache first before
683 routing. Affected file is silcd/command.c.
685 * Added channels topic announcements. Affected file is
686 silcd/packet_receive.c and silcd/server.c.
688 * Fixed the silc_server_send_notify_topic_set to really destine
689 the packet to channel. Affected file silcd/packet_send.c.
691 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
692 library. Affected file lib/silcclient/client_notify.c.
694 * Added UMODE announcements. Affected file silcd/server.c.
696 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Memory leak fixes in:
700 lib/silcutil/silcsockconn.c
701 lib/silcske/silcske.c
704 lib/silccrypt/silcpkcs.c
705 lib/silccore/silccommand.c
706 lib/silccore/silcidcache.c
711 * ROBOdoc documented the lib/silcske/groups.h file and a
712 bit changed the interface for better.
714 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
716 * Update the client entry context in the ID cache after
717 nick change. Affected file lib/silcclient/command.c.
718 Fixes the CUMODE command when regaining founder privileges,
719 and a little WHOIS problem.
721 * Fixed silc_net_gethostbyname to correctly call the
722 inet_ntop. Affected file lib/silcutil/silcnet.c.
724 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
726 * Added IPv6 support checking to the configure.in.pre, added
727 also --enable-ipv6 option to override the check. Affected
728 file configure.in.pre.
730 * The silc_thread_create now calls the start function
731 directly if threads support is not compiled in. Removes
732 ugly #ifdef's from generic code. Affected files are
733 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
735 * Added silc_net_gethostby[name/addr]_async to asynchronously
736 resolve. Affected files are lib/silcutil/silcnet.[ch].
738 * Added support for rendering IPv6 based server, client and
739 channel IDs. Affected file lib/silcutil/silcutil.c.
741 * Added support for creating IPv6 based server IDs. Affected
742 file is silcd/serverid.c.
744 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
746 * Added silc_net_gethostby[addr/name] into the
747 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
748 routines. Added silc_net_is_ip[4/6]. Affected file is
749 lib/silcutil/unix/silcunixnet.c. All routines that take
750 address as argument now supports both IPv4 and IPv6 addresses.
752 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
754 * Fixed LIST command reply sending in server. Affected file
757 * Server now sends the kicker's client ID in the KICK notify
758 to the kicked client. Affected file silcd/command.c.
760 * The client library now parses the kickers client ID and
761 UI displays it. Affected files lib/silcclient/client_notify.c
762 and irssi/src/silc/core/silc-channels.c, module-formats.c.
764 * Made all payload parsing function prototypes consistent.
765 They all take now const unsigned char * and uint32 pair as
766 the payload data instead of SilcBuffer. Changes all around
767 the source tree. Other unsigned char* -> const unsigned char*
768 changes around the tree as well.
770 * Optimized SFTP client and server packet sending not to
771 allocate new buffer for each packet but to recycle the
772 first allocated buffer. Affected files are
773 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
775 * Optimized the SFTP client to use SilcList instead of
776 SilcDList for requests, because it is faster. Affected file
777 is lib/silcsftp/sftp_client.c.
779 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
780 into lib/silccore/silcid.[ch].
782 Renamed silcpayload.[ch] into silcargument.[ch].
784 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
786 * If client entry is deleted with active key agreement
787 session, abort the session.
789 The silc_client_abort_key_agreement now calls the completion
790 callback with new SILC_KEY_AGREEMENT_ABORTED status.
792 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
795 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
797 * Don't use __restrict in older GCC's. Affected file is
798 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
800 * silc_net_localhost now attempts to reverse lookup the
801 IP/hostname. Affected file lib/silcutil/silcnet.c.
803 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
804 command. It can be used to gain founder privileges at
805 the same time when joining the channel.
807 Defined that the SILC_NOTIFY_TYPE_KICKED send the
808 kicker's client ID as well. Updated protocol specs.
810 Defined that the server must send SILC_COMMAND_IDENTIFY
811 command reply with error status to client who sent
812 private message with invalid client ID.
814 Updated the protocol specification.
816 * Added silc_server_send_command_reply to send any
817 command reply. Affected file silcd/packet_send.[ch].
819 * Added silc_id_payload_encode_data to encode ID payload
820 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
822 * The server now send IDENTIFY command reply with error
823 status if client ID in private message is invalid. Affected
824 file silcd/packet_receive.c.
826 * Save the server key file with server's IP address in
827 the filename instead of hostname. The affected file is
828 irssi/src/silc/core/client_ops.c.
830 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
835 * Added libtool support for compiling shared objects in
836 lib/silcsim. Affected file configure.in.pre and
837 lib/silcsim/Makefile.am. Original patch by cras.
839 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Pid file configuration, and server's config file fixes
842 patch by toma. Updated CREDITS file.
844 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Fixed silc_client_channel_message to not try to decrypt
847 the message twice if it resolved the destination client
848 information. This could cause of dropping one channel
849 message. Affected file lib/silcclient/client_channel.c.
851 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
853 * Added silc_client_run_one into lib/silcclient/silcapi.h and
854 lib/silcclient/client.c. This function is used when the SILC
855 Client is run under some other scheduler, or event loop or
856 main loop. On GUI applications, for example this may be
857 desired to used to run the client under the GUI application's
858 main loop. Typically the GUI application would register an
859 idle task that calls this function multiple times in a second
860 to quickly process the SILC specific data.
862 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
864 * Fixed silc_server_drop() for dropping the supplementary
865 groups as well, this could cause a security hole on some
868 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
873 * Write PID file after dropping privileges. Added -F option
874 to run server on foreground. A patch by debolaz.
875 Affected files silcd/server.c, silcd/silcd.c.
877 * Fixed MOTD to return the MOTD file server name. Affected
878 file silcd/command.c.
880 * Added INFO command reply handling to the Irssi SILC Client.
881 Affected file irssi/src/silc/core/client_ops.c.
883 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Fixed the silc_idcache_list_* routines to really support
886 the dynamic list. Fixes a crash. Affected file is
887 lib/silccore/silcidcache.c.
889 * Fixed the LIST command reply to really call LIST command's
890 pending callbacks. Affected file silcd/command_reply.c.
892 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Update conn->local_entry->nickname after giving NICK
895 command. Affected file lib/silcclient/command.c.
897 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
899 * Added the [pid] option to the silcd configuration file
901 Affected files: serverconfig.[ch] and silcd.c
903 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
905 * Save fingerprint in WHOIS command reply in server.
906 Affected file silcd/command_reply.c.
908 * Fixed NICK commands pending callback registration.
909 Affected file lib/silcclient/command.c.
911 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
913 * Use ++server->cmd_ident when sending commands in server,
914 instead of random number. Affected file silcd/command.c.
916 * Fixed GETKEY command reply to call actually GETKEY pending
917 command callbacks. Affected file silcd/command_reply.c.
919 * A bit stricter check for nicknames. Check for same nickname
920 in NICK command also. Affected file silcd/command.c.
922 * Do not call INFO command everytime client ID changes, only
923 during first connecting. Affected file lib/silcclient/client.c.
925 * Set the new nickname only after successful command reply for
926 NICK command is returned by server. Affected file
927 lib/silcclient/command.c.
929 * Remove nicknames from nicklist during server_signoff notify.
930 Should fix /NAMES bit more. The affected file is
931 irssi/src/silc/core/silc-channels.c.
933 * Added `fingerprint' field to the SilcIDListData in the
934 silcd/idlist.h to hold the fingerprint of the client's
937 Send the fingerprint of the client's public key in WHOIS
940 Affected files silcd/command.c, and silcd/idlist.[ch].
942 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
943 create fingerprint from given data.
945 * Show the fingerprint of the client's public key in WHOIS.
946 Affected files irssi/src/module-formats.[ch] and
947 irssi/src/silc/core/client_ops.c.
949 * Format the multiple same nicknames also during JOIN and
950 NICK_CHANGE notifys. Affected file is
951 lib/silcclient/client_notify.c.
953 * Do not print error on screen for invalid private message
954 payload since it can come if someone is sending private
955 messages with wrong key. Affected file
956 lib/silccore/silcprivate.c.
958 * Fixed multiple concurrent /PING crash. Affected file
959 lib/silcclient/command.c.
961 * Changed the wrong ID encoding. All IP addresses must be
962 in MSB first order in encoded format. They were encoded
963 wrong and was in LSB format. Affected files are
964 silcd/serverid.c, lib/silcutil/silcutil.c.
966 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
968 * Call the `connect' client operation through the scheduler
969 in case of error. Affected file lib/silcclient/client.c.
971 * Call the `failure' client operation even if the error
972 occurred locally during a protocol. Affected file is
973 lib/silcclient/protocol.c.
975 * Added support of sending LIST command to router from normal
976 server. This way normal server can get list of all channels
977 in the network too. Fixed the channel list sending in the
978 server too. Affected files are silcd/command.c, and
979 silcd/command_reply.[ch].
981 * Added silc_server_update_channels_by_server and
982 silc_server_remove_channels_by_server. They are used during
983 disconnection of primary router and in backup router protocol.
984 Affected file silcd/server_util.[ch], silcd/server.c and
985 silcd/server_backup.c.
987 * Fixed channel adding to global list in IDENTIFY command
988 reply in server. Affected file silcd/command_reply.c.
990 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
992 * If the incoming packet type is REKEY or REKEY_DONE process
993 that packet always synchronously. Fixes yet another MAC
994 failed error on slow (dialup) connections. Affected file
995 lib/silcclient/client.c and silcd/server.c.
997 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Call check_version SKE callback for initiator too. Affected
1000 file lib/silcske/silcske.c.
1002 * Implemented fix for security hole found in the SKE that was
1003 fixed in the specification few days back; the initiator's
1004 public key is now added to the HASH value computation.
1005 Added backwards support for the old way of doing it too, for
1006 old clients and old servers. Affected file is
1007 lib/silcske/silcske.c.
1009 * Enabled mutual authentication by default in SKE. If initiator
1010 is not providing mutual authentication the responder will
1011 force it. This will provide the proof of posession of the
1012 private key for responder. The affected files are
1013 lib/silcclient/protocol.c and silcd/protocol.c.
1015 * Do not cache anymore the server's public key during SKE.
1016 We do mutual authentication so the proof of posession of
1017 private key is done, and if the server is authenticated in
1018 conn auth protocol with public key we must have the public
1019 key already. Affected file silcd/protocol.c.
1021 * Added new global debug variable: silc_debug_hexdump. If
1022 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1023 file lib/silcutil/silclog.[ch].
1025 * Fixed compilation warning due to char * -> const char *.
1026 Affected files lib/silcutil/silcnet.h, and
1027 lib/silccore/silcauth.[ch].
1029 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Fixed CMODE command when new channel key was created. If
1032 the creation failed the old key was removed. Next time giving
1033 same command would crash the server since the old key was
1034 freed already. Affected file silcd/command.c.
1036 * Fixed the silc_server_announce_get_channels to not crash
1037 on reconnect. Affected file silcd/server.c.
1039 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Added silc_log_set_debug_string function to set a regex
1042 string to match for debug output. Only the function names,
1043 or filenames matching the given debug string is actually
1044 printed. This way it is possible to filter out those debug
1045 strings that user is not interested in.
1047 Fixed a bug in silc_string_regexify.
1049 Affected files lib/silcutil/silclog.[ch], and
1050 lib/silcutil/unix/silcunixutil.c.
1052 * Changed the -d options in both server and Irssi SILC client
1053 to take the debug string as argument. Affected files
1054 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1056 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1058 * Added silc_hash_babbleprint to create a Bubble Babble
1059 Encoded fingerprint. The encoding is developed by Antti
1060 Huima (draft-huima-babble-01.txt), and it creates human
1061 readable strings out of binary data. Affected file
1062 lib/silccrypt/silchash.[ch].
1064 * Print the babble print now in addition of fingerprint as well
1065 in Irssi SILC client. Affected files are
1066 irssi/src/fe-common/silc/module-formats.[ch],
1067 irssi/src/fe-common/silc/core/client_ops.c.
1069 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Fixed a security problem found in SKE. The initiator's
1072 public key too is now added to the HASH hash value creation
1073 which is signed by the responder to create the SIGN value.
1074 This will prevent anyone in the middle to lie to the responder
1075 about the initiator's public key. If this is done now, the
1076 man in the middle will get caught. Updated the protocol
1079 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Better installation directory handling. Configure module
1082 paths and other paths automatically to example_silc* files
1083 in doc/. A patch by toma.
1085 * Fixed compiler warning from MPI library, and from SILC RNG.
1088 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1089 It can be configured with ./configure. A patch by toma.
1091 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Find correct make to use in prepare-clean. A patch by
1094 toma. Affected file prepare-clean.
1096 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1098 * Added irssi variables use_auto_addr, auto_bind_ip,
1099 auto_bind_port and auto_public_ip.
1101 * Changed the interface for silc_client_send_key_agreement
1102 in lib/silcclient/silcapi.h
1106 irssi/src/silc/core/silc-core.c
1108 lib/silcclient/silcapi.h
1109 irssi/src/silc/core/silc-channels.c
1110 lib/silcclient/client_keyagr.c
1113 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Added silc_pkcs_public_key_compare to compare two
1116 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1118 * Check that the client who set the founder mode on the
1119 channel is the same client that is giving the founder
1120 mode to itself. It is done by comparing the saved public
1121 key (it is saved even in the authentication is passphrase).

1130 client library. Affected file lib/silcclient/client.c.
1132 * Fixed the silc_client_packet_parse to not to increase
1133 the packet sequence number if the conn->sock and the
1134 current socket connection is not same. This can happen
1135 for example during key agreement when the conn includes
1136 multiple socket connections (listeners). Affected file
1137 lib/silcclient/client.c.
1139 * The sender of the file transfer request now provides also
1140 the pointer (listener) for the key exchange protocol. If
1141 the listener cannot be created then it sends empty key
1142 agreement and lets the receiver provide the listener.
1144 Added `local_ip' and `local_port' arguments to the
1145 silc_client_file_send. If they are provided they are used,
1146 if not then it will attempt to find local IP address, if
1147 not found or bind fails then the remote client will provide
1150 Affected files are lib/silcclient/client_ftp.c and
1151 lib/silcclient/silcapi.h.
1153 * Extended the FILE SEND command to support defining the

1160 of the client's public key (if the proof of posession of the
1161 corresponding private key is verified by the server).
1162 Updated to the protocol specification.
1164 * Added support of receiving the client's public key's
1165 fingerprint in command reply in client library. Affected
1166 file is lib/silcclient/command_reply.c, and
1167 lib/silcclient/idlist.[ch].

1226 preserve the WHOWAS info for the client. Affected file
1227 silcd/server_util.c.
1229 * Fixed SERVER_SIGNOFF notify handling in the server. The
1230 server is now able to process incoming SERVER_SIGNOFF notify
1231 for a server that it doesn't even know about. It will remove
1232 the clients provided in the notify. Affected file
1233 silcd/packet_receive.c.
1235 * Check for partial packet in data queue after every packet that
1236 was found from the queue. Return and wait for more data if
1237 there is partial data in queue. Affected file is

1255 irssi/src/fe-common/silc/module-formats.[ch].
1257 * Wrote a help file for FILE command.
1259 * Added silc_rng_global_get_byte_fast to get not-so-secure
1260 random data as fast as possible. Random data is read from
1261 /dev/urandom if available and from the SILC RNG if not
1262 available. It is used in padding generation. Affected file
1263 lib/silccrypt/silcrng.[ch].
1265 * All packets in client library are now processed synchronously.
1266 Optimized packet processing a lot. Affected file
1267 lib/silcclient/client.c.

1278 * Assure that silc_client_notify_by_server_resolve does not
1279 resolve the client information multiple times. If it cannot
1280 be found by the first it cannot be found at all. Affected
1281 file lib/silcclient/client_notify.c.
1283 * Fixed WHOWAS command reply calling. Affected file
1284 lib/silcclient/command_reply.c.
1286 * Removed all references to silc_idlist_get_client from the
1287 Irssi SILC client since that call is internal call used by
1288 the library. The Irssi SILC client will use now client
1289 retrieval functions found in silcapi.h.
1291 * Fixed a bug in resolving nickname info before sending
1292 private message. It used freed memory. Affected file
1293 irssi/src/silc/core/silc-servers.c.

1315 Affected file lib/silcutil/silcnet.[ch].
1317 * If key exchange or rekey protocol is active for a connection
1318 parse all packets syncronously since there might be packets
1319 in packet queue that we are not able to process without first
1320 processing packets before them. Affected file silcd/server,
1321 lib/silcclient/client.c.
1323 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1324 whether library should continue processing the packet.
1325 Affected file lib/silccore/silcpacket.h.

1375 Make sure also that USERS command reply does not resolve
1376 twice information. Affected file is
1377 lib/silcclient/command_reply.c.
1379 Make sure that silc_client_get_clients_by_list does not
1380 resolve twice same information.
1382 * Check for valid client->id in the silc_server_free_client_data.
1383 Affected file silcd/server.c.
1385 * Fixed /GETKEY nick@server not to crash if the server entry

1398 * Call the silc_server_udpate_servers_by_server in the
1399 primary router that comes back online in the backup resuming
1400 protocol. Otherwise it routes packets wrong. Affected file
1401 silcd/server_util.[ch], silcd/server_backup.c.
1403 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1406 lib/silcutil/silcbuffmt.[ch].
1408 * Redefined the SILC packet header to include the padding
1409 length. Affected file lib/silccore/silcpacket.[ch].
1411 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1412 length for maximum padding up to 128 bytes). Affected
1413 file lib/silccore/silcpacket.h.
1415 * Removed all backwards support for old 0.5.x MAC thingies.
1416 The SILC packet header change makes it impossible to be
1417 backwards compatible.
1419 * Send the ENDING packet with timeout in the backup resuming
1420 protocol. This is to assure that all routers has connected
1421 to the primary router. Affected file silcd/server_backup.c.
1423 * Changed the RNG to take the first IV from random data. It
1424 used to take it from zero actually. Changed the RNG also
1425 to use /dev/urandom during session. /dev/random is used
1426 in initialization. Affected file lib/silccrypt/silcrng.[ch].

1431 (the packet length) encrypted. Affected files aroung the
1432 code tree, lib/silccore/silcpacket.[ch]. Removed the
1433 SilcPacketCheckDecrypt callback. It is not needed anymore
1434 since the silc_packet_receive_process will determine now
1435 whether the packet is normal or special.

1448 * Allow backup router to announce servers. All servers
1449 announced by backup router are added to the global list
1450 automatically. Update hte server's socket to our primary
1451 router also when backup router announces a server.
1452 Affected file silcd/packet_receive.c.
1454 * Do not update the client->router in the function
1455 silc_server_udpate_clients_by_server if the client is on
1456 global list. We might fail to find any specific server
1457 for locally connected clients and local cell clients. They
1458 should still use the `from' and not `to' as client->router.
1459 This fixes backup router resuming protocol. Affected file
1460 silcd/server_util.c.
1462 * Decrease channel statistics count only if the channel
1463 deletion worked. Affected files are silcd/server.c and
1464 silcd/server_util.c.
1466 * Added silc_server_update_servers_by_server to update origin
1467 of all server entries. Used during backup router protocol.

1484 to the router it came from. Affected file is
1485 silcd/packet_send.c. Fixed memory leak too.
1487 * Announce informations for incoming router connection, but
1488 only after checking if it is replaced by backup router.
1489 Affected file silcd/packet_receive.c.
1491 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1494 router environment. Affected file silcd/server_backup.c.
1496 * Route packet only to one router in the function
1497 silc_server_packet_send_to_channel. Affected file is
1498 silcd/packet_send.c.
1500 * Fixed silc_server_send_notify_dest to set the broadcast
1501 flag. Fixed the silc_server_send_notify_topic to actually
1502 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1503 Affected file silcd/packet_send.c.
1505 * Changed the SFTP Filesystem interface. Changed the
1506 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1507 the filesystem operation function. The SilcSFTPFilesystem
1508 is now a context that is allocated by all filesystem allocation
1509 functions and it already includes the operations structure
1510 and filesystem specific context. It is given as argument
1511 now to the silc_sftp_server_start. This made the interface
1512 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1513 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1515 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1517 * Changed the backup router adding and getting interfaces
1518 in the server. The router that will be replaced by the
1519 specified backup router is now sent as argument. Affected

1580 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1581 in the server to indicate disabled entry. All data read
1582 from the connection will be ignored and no data is sent
1583 for entry that is disabled. Affected files are
1584 silcd/idlist.h, silcd/server.c.

1638 of the internet draft is lib/silccore/silcpacket.h.
1640 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1641 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1642 is used as part of backup router protocol when the primary
1643 router of the cell is back online and wishes to resume
1644 the position as primary router.
1646 * Redefined the MAC generation keys in the protocol. The
1647 same key is not used anymore in both direction. Both
1648 direction will now use different keys for sending and
1649 receiving. This fixes a potential security flaw. This
1650 change causes incompatibilities in the protocol.
1652 * Redefined also the MAC computation from the packet.
1653 An packet sequence number is now added to the MAC
1654 computation. This prevents possible replay attacks against
1655 the protocol. This change too causes incompatibilities
1658 Added `sequence' field to the SilcPacketContext to hold
1659 the current sequence number for the packet.
1661 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Added `created' field to the SilcIDListData in the file
1664 silcd/idlist.h to indicate the time when the entry was
1667 * Added `created' field to the SilcChannelEntry too. Affected
1668 file silcd/idlist.h.
1670 * Added `creation_time' aguments to all the announcement functions
1671 in the server. If it is provided then only the entries that
1672 was created after the provided time frame are actually
1673 announced. Affected file silcd/server.[ch].
1675 * The protocol says that the Channel ID's IP address must be
1676 based on the router's IP address. Added check for this in
1677 the silc_server_new_channel when processing incoming New Channel
1678 Payload. Affected file silcd/packet_receive.c.
1680 * Print out the correct version with --version in SILC client.
1681 Affected file irssi/src/silc/core/silc-core.c.
1683 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Fixed WHOWAS command to check for completnes of the client
1686 entry always, not just when the command is coming from client.
1687 Affected file silcd/command.c.
1689 * Added new function silc_server_packet_queue_purge to purge the
1690 outgoing data queue to the network. After the function returns
1691 it is guaranteed that the outgoing packet queue is empty.
1692 Affected file silcd/packet_send.[ch].
1694 * Purge the outgoing packet queue in the rekey protocol's final
1695 callback to assure that all rekey packets go to the network
1696 before quitting the protocol. Affected file silcd/server.c.
1698 * Added silc_client_packet_queue_parse as similar function as
1699 in server to the client library. The affected file is
1700 lib/silcclient/client.c.
1702 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Splitted silcd/server.c and created silcd/server_util.[ch]
1705 for utility functions.
1707 * Added new socket flag SILC_SF_DISABLED to indicate that the
1708 connection is open but nothing can be sent to or received from
1709 the connection. Affected file lib/silcutil/silsockconn.[ch].
1710 The checking for disabled socket is checked in the low level
1711 silc_socket_write and silc_socket_read functions.
1713 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Allow only nicknames and channel names that fits into the
1716 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1718 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1720 * When processing JOIN command reply in server check that if
1721 the channel exists in our global list we'll move it the local
1722 list. Affected file silcd/command_reply.c.
1724 * Fixed the check whether client is joined on the channel already
1725 in JOIN command. Affected file lib/silcclient/command.c.
1727 * Fixed the JOIN command reply to check whether the channel
1728 already exists. Affected file lib/silcclient/command_reply.c.
1730 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Added silc_ske_status_string to map the SKE error numbers
1733 to readable strings. The affected files are
1734 lib/silcske/silcske[_status].[ch].
1736 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Do not show the private channels on the WHOIS channel list
1739 as it is not allowed by the protocol. The affected file is
1742 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Assure that the packet length digged from the actual packet
1745 is something sensible in the silc_packet_decrypt_rest_special
1746 in lib/silccrypt/silcpacket.c.
1748 * Free and NULL the allocated pointer in silc_hmac_alloc if
1749 the HMAC allocation fails. The affected file is
1750 lib/silccrypt/silchmac.c.
1752 * Print the selected security properties to the log files in
1753 the server. Affected file silcd/protocol.c.
1755 * Add SKE's reference counter even if calling the completion
1756 callback manually. Otherwise it goes negative, although it
1757 does not cause any problems. The affected file is
1758 lib/silcske/silcske.c.
1760 * Remove the client entry with short timeout after giving the
1761 KILL command. Affected file lib/silcclient/command.c.
1763 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1764 case all found clients are already disconnected (WHOWAS would
1765 found them) in the server. Affected file silcd/command.c.
1767 * Update the last_receive (time of last data received) to be
1768 updated only when received private or channel message so that
1769 the idle time showed in WHOIS makes more sense.
1771 * Added boolean field `valid' in to the SilcClientEntry in the
1772 client library to indicate whether the entry is valid or not.
1773 This fixes the nickname change bug on channel when changing
1774 the nickname to be same than the old (like nick to Nick) the
1775 nickname formatter doesn't set the new nick anymore to Nick@host.
1776 Affected file lib/silcclient/idlist.[ch].
1778 * Now actually fixed the nickname changing on disconnection.
1779 Added new function silc_change_nick to the Irssi SILC Client.
1780 Affected file irssi/src/silc/core/client_ops.c,
1781 irssi/src/silc/core/silc-nicklist.[ch].
1783 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1785 * Check that the public key exists in the GETKEY command before
1786 trying to encode it. Affected file silcd/command.c.
1788 * Print some notifications on received public keys with GETKEY
1789 command in the Irssi SILC Client. Affected files are
1790 irssi/src/fe-common/silc/module-formats.[ch],
1791 irssi/src/silc/core/client_ops.c.
1793 * Use IDENTIFY command to resolve the server information in the
1794 GETKEY command instead of INFO command. Affected file
1795 lib/silcclient/command.c.
1797 * All command reply functions in the client library now calls
1798 the pending command reply callbacks even if an error has
1799 occurred. The server has done this a long time and now it was
1800 time to move the client library to this as well. Now all
1801 errors can be delivered back to the pending command reply
1802 callbacks if necessary. Affected files are
1803 lib/silcclient/command[_reply].[ch].
1805 * Change the nickname on disconnection back to the username
1806 because in reconnect the server will enforce it to it anyway.
1807 Affected file irssi/src/silc/core/silc-servers.c.
1809 * Fixed a config file parsing bug in the Irssi SILC client.
1810 Affected file irssi/src/silc/core/clientconfig.c.
1812 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * When printing the channel mode on JOIN, verify that the
1815 channel key and channel's HMAC are valid. Affected file
1816 irssi/src/silc/core/client_ops.c.
1818 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1821 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1822 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1824 * Removed channel key rekey task deleting from the function
1825 silc_server_save_channel_key. Affected file silcd/server.c.
1826 Added explicit timeout task context instead that is used to
1827 delete the task if we are registering a new task before the
1828 new task has elapsed.
1830 * When channel key rekey occurs the client library now saves
1831 the old channel key for a short period of time (10 seconds) and
1832 is able to use it in case some is still sending channel
1833 messages encrypted with the old key after the rekey. Affected
1834 file lib/silcclient/[idlist.h|client_channel.c].
1836 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1838 * Added check to the silc_server_new_id_real to not accept
1839 new ID if it is the sender's own ID. Affected file is
1840 silcd/packet_receive.c.
1842 * Assure that we do not announce ourself or the one we've
1843 sending our announcements when we're router and are announcing
1844 servers to our primary router. Affected file silcd/server.c.
1846 * Fixed silc_server_command_identify_check_client to assemble
1847 correct WHOIS packet. It send corrupted WHOIS packet and
1848 caused problem with router to router connections. Affected
1849 file silcd/command.c.
1851 Fixed also silc_server_command_whois_check the same way
1852 as for the IDENTIFY command.
1854 * Added new SilcIDListStatus to the server in the SilcIDListData
1855 structure. The status now includes the current status of
1856 the entry (like registered, resolved etc.). Affected file
1857 silcd/idlist.[ch]. Defined a bunch of different status types
1858 as well. This replaced the old boolean registered field as well.
1860 Added resolve_cmd_ident field to the SilcClientEntry structure
1861 too so that if the entry is for example being resolved so
1862 another command may attach to the same pending command reply
1863 without requiring to resolve the same entry again. This concept
1864 should optimize the WHOIS and the IDENTIFY resolving under
1865 heavy load by taking away unnecessary resolving for entries
1866 that are being resolved already.
1868 Added support for adding multiple pending commands for one
1869 command idenfier. Affected file silcd/command[_reply].[ch].
1871 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1872 before deleting the data. Otherwise the hash table will have
1873 freed data in comparison functions. Affected file is
1874 silcd/command_reply.c.
1876 * Fixed silc_idlist_replace_client_id to add the new entry to
1877 the cache with NULL nickname. Otherwise there will be invalid
1878 memory as the nickname after the nickname is freed. Affected
1879 file silcd/packet_receive.c.
1881 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1882 saved into wrong slots because the previous number of entries
1883 was not taken into account. Affected file silcd/idlist.c.
1884 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1886 * If we are router and we receive JOIN notify to a channel that
1887 does not have any users then notified client is marked as the
1888 channel founder, as it is it. The affected file is
1889 silcd/packet_receive.c
1891 * Added to the extended hash table API's table_del_*ext functions
1892 the destructor as argument too, so that the caller can decide
1893 which destructor to use or whether to use destructor at all.
1894 Affected file lib/silcutil/silchashtable.[ch].
1896 * Fixed ID Cache purging. It actually deleted the entries from
1897 the hash table after the data was freed. The hash table ended
1898 up comparing freed memory. The affected file is
1899 lib/silccore/silcidcache.c.
1901 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1903 * Fixed Irssi SILC client's KILL command's HELP syntax.
1905 * The USERS command now resolves the detailed user information
1906 if the userinfo field is missing. Affected file is
1907 lib/silcclient/command_reply.c.
1909 * Do not print error in silc_file_read if the read file does
1910 not exist. Just silently return NULL. Affected file is
1911 lib/silcutil/silcutil.c.
1913 * Fixed the silc_log_output to not wine about NULL filename
1914 and to not create some bogus " " filename. Affected file is
1915 lib/silcutil/silclog.c.
1917 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Fixed various printing bugs on the user interface in the
1920 Irssi SILC Client. Minor changes that were forgotten from
1923 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Fixed the configure.in.pre and the compilation and distribution
1926 environment to support the new autoconf 2.52. That version is
1927 now required to compile the CVS trunk.
1929 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1932 to generally parse user@fqdn format strings. Affected file
1933 lib/silcutil/silcutil.c.
1935 * Added nickname_format and nickname_force_format fields to the
1936 SilcClientParams structure. The first one defines the format
1937 for the nicknames that the library will enforce if the receives
1938 multiple same nicknames. The second one is boolean value and
1939 can be used to force the library to always enforce the format
1940 to the nicknames regardles whether there are multiple nicknames
1941 or not. This configurable formatting was employed to flexibly
1942 support accessing multiple nicknames from the user interface.
1943 The userinterface can now set the nicknames to what ever format
1944 they prefer. Affected file lib/silcclient/silcapi.h.
1946 Added function silc_client_nickname_format to the file
1947 lib/silcclient/idlist.c. It performs the nickname formatting.
1949 Added new field `hostname´ to the SilcClientEntry context.
1950 It holds the hostname of the client. Affected file is
1951 lib/silcclient/idlist.h.
1953 * Irssi SILC Client sets the nicknames in nick@hostn format.
1954 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1955 irssi/src/silc/core/silc-core.c.
1957 The WHOIS printing now also shows both the real nickname and
1958 the formatted nickname so that user knows how to access the
1959 user if there are multiple same nicknames cached. Affected
1960 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1961 printing formatting too to take the hostname now as a separate
1962 argument. The Affected file is
1963 irssi/src/fe-common/silc/modules-formats.[ch].
1965 * Changed the silc_client_get_clients_local to accept the formatted
1966 nickname as argument. It accepts the real nickname too but the
1967 formatted nickname can be used to find the true entry from
1968 multiple entries. Affected file lib/silcclient/silcapi.h and
1969 lib/silcclient/idlist.c.
1971 * Added nickname_format_parse field to the SilcClientParams.
1972 It is a callback function provided by the application to parse
1973 the nickname out of the formatted nickname string. The library
1974 calls it to get the nickname from the formatted string. Since
1975 the application generally knows better the format of the nickname
1976 string it parses it instead of the library, even though library
1977 encodes the formatted string. If the callback function is not
1978 provided then the library will use the string as is. The
1979 affected file is lib/silcclient/silcapi.h.
1981 * All the nickname strings passed to the client library in
1982 commands are now expected to be formatted nickname strings.
1983 If the command does not support the formatted nickname string
1984 it will assume that the sent string is the actual nickname.
1985 Affected file lib/silcclient/command.c.
1987 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * Added public key authentication support to OPER and SILCOPER
1990 commands in the client library. Affected file is
1991 lib/silcclient/command.c.
1993 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Changed the get_auth_methdod client operation to be asynchronous.
1996 It can be async if the application resolves the authentication
1997 method from the server during the negotiation. Added new
1998 SilcGetAuthMeth completion callback that the application will
1999 call after resolving the authentication method.
2001 Added function silc_client_request_authentication_method that
2002 the application can use to resolve the authentication method
2003 from the server. Added also SilcConnectionAuthRequest callback
2004 that the library will call after the server has replied. The
2005 application can call this function if it does not know the
2006 current authentication method.
2008 Affected files are lib/silcclient/client.c and
2009 lib/silcclient/silcapi.h.
2011 * The Irssi SILC client now automatically resolves the authentication
2012 method incase any configuration information is not present (and
2013 currently there never is). The affected file is
2014 irssi/src/silc/core/client_ops.c.
2016 * Fixed public key authentication from the client library.
2017 Affected file lib/silcclient/protocol.c. Changed also the
2018 protocol specification about the public key authentication in
2019 the connection authentication protocol. The actual data to be
2020 signed is now computed with a hash function before signing.
2022 * Fixed the public key authentication from the server as well.
2023 Affected file silcd/protocol.c.
2025 * Removed the mlock()'s from the memory allocation routines.
2026 Affected file lib/silcutil/silcmemory.c. The ./configure does
2027 not check anymore for the mlock(). Affected file is
2030 * Fixed USERS command in server to allow the execution of the
2031 command for private and secret channels if the client sending
2032 the command is on the channel. Affected file silcd/command.c.
2034 * Fixed silc_client_get_clients_local to return the clients
2035 count correctly. It could return wrong value. Affected file
2036 lib/silcclient/idlist.c.
2038 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2041 types. The assembler optimizations seemed not to like 64-bit
2042 data types. The assmebler optimizations thus are now enabled
2043 also for BSD systems as opposed to only enable them for Linux.
2045 * Do not check for threads at all on BSD systems. Affected
2046 file configure.in.pre.
2048 * Removed -n and -h options from the Irssi SILC Client since
2049 they are not used in silc.
2051 * Fixed the prime generation to assure that the first digit
2052 of the generated random number is not zero since our conversion
2053 routines does not like number strings that starts with zero
2054 digit. If zero digit is seen the random number is regenerated.
2055 This caused some corrupted RSA keys when the zero first digit
2056 was met. Affected file lib/silcmath/silcprimegen.c.
2058 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Fixed WIN32 configuration in the ./configure script.
2061 Fixed to include xti.h on environments that has it.
2062 Patches by Carsten Ilchmann and andrew.
2064 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Changed the silc_id_create_client_id to be collision
2067 resistant. It is now assured that there cannot be created
2068 two same client ID's. I suspect that some weird bugs in
2069 the server were actually caused by duplicate Client IDs.
2070 Affected file silcd/serverid.[ch]. A router receiving
2071 new ID now also assures and informs the sending server
2072 if the ID caused collision.
2074 * Changed the silc_id_create_channel_id to also assure that
2075 there are no collisions.
2077 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Statement about ignoring the Mutual Authentication flag when
2080 performing rekey with PFS was a bit misleading. It is ignored
2081 if it was set in the initial negotiation, it cannot be even
2082 set in the rekey. Fixed in the ke-auth draft. Started the
2083 new versions of the protocol drafts in the doc/.
2085 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * Fixed a bug in silc_client_command_identify_save when saving
2088 new channel information. The channel name was no duplicated
2089 and caused crash on exit. Affected file is
2090 lib/silcclient/command_reply.c.
2092 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Fixed the getkey command handling in the server. Send just
2095 empty OK reply to the sender if the key could not be fetched
2096 (but everything else was ok, like the key just was not available).
2097 Changed the public key parameter to optional in the protocol
2098 specs so that empty OK reply can be sent. Affected file
2101 Added a message to Irssi SILC client to tell to user if the
2102 server did not return a public key.
2104 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2106 * Fixed a channel key regeneration bug. It registered new
2107 timeout tasks exponentially until all system resources were
2108 used. Affected file silcd/server.c.
2110 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2112 * Added the SILC Document generator to the scripts/silcdoc.
2113 It can be used to generate the Toolkit Reference Manual out
2114 of the source tree. Internally it will also use the RoboDoc
2115 generator now imported in util/robodoc.
2117 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Added couple of return's in rekey protocol if error orccurred
2120 during the protocol. The execution must be terminated.
2121 Affected file silcd/protocol.c. Also, terminate the protocol
2122 always with timeout.
2124 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * The client's Client ID was created initally from the wrong
2127 nickname (it could have been in format nick@host) in the
2128 silc_server_new_client. Affected file silcd/packet_receive.c
2130 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2132 * Added some SILC_LOG_ERROR's to various error conditions
2133 if client could not be added to ID cache. Affected files
2134 silcd/packet_receive.c and silcd/server.c.
2136 * When client's sock->user_data is freed, NULL also the
2137 client->router and client->connection pointers. Added check
2138 for these pointers being NULL to various places around the
2139 code. Affected file silcd/server.c.
2141 * Added client->data.registered == TRUE checks to various
2142 places around the code to assure that unregistered client's
2143 are not handled when it is not allowed. Affected file
2146 * Added `bool registered' fields to all
2147 silc_idlist_[server|client]_get_* routines to indicate whether
2148 the fetched client needs to be registered or not. Affected
2149 file silcd/idlist.[ch].
2151 * Add your own entry as registered to the ID cache in the
2152 server. Affected file server.c.
2154 * Fixed a bug in silc_server_new_server. The SilcServer was
2155 set as the new server's context instead of SilcServerEntry.
2156 This naturally caused some weird bugs.
2158 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Do not delete the channel rekey task when adding it
2161 for in silc_server_create_channel_key.
2163 * Changed the silc_server_create_channel_key to return
2164 TRUE or FALSE to indicate the success of the channel key
2167 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Fixed MSVC++ project files and added missing files to

2175 does not have it defined. Affected files are
2176 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2178 * Fixed buffer overflow from Irssi SILC Client. Affected
2179 file irssi/src/fe-common/core/themes.c.
2181 * Fixed double free in client library in the file
2182 lib/silcclient/client.c when disconnecting from server.
2184 * Applied double free patch from cras to Irssi SILC client.
2185 Affected files irssi/src/core/[modules/expandos].c
2187 * Fixed the disconnection handling to Irssi SILC Client.
2188 The application must call silc_client_close_connection
2189 in ops->connect client operation in case of failure of
2190 the connection. Affected file is
2191 irssi/src/silc/core/client_ops.c.
2193 * Do not set sock->protocol to NULL in the function
2194 silc_client_close_connection after executing the protocol's
2195 final callback since the sock might not be valid anymore.
2196 Affected file lib/silcclient/client.c.
2198 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Do not enable SILC_THREADS if the linking with libpthread
2201 did not happen. Affected file configure.in.pre.
2203 * Added notion to protocol specification that server must
2204 verify the sent authentication payload with CMODE when
2205 setting the channel founder key. Implemented it to the
2206 server. Affected file silcd/command.c.
2208 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Added _EXTRA_DIST SILC distribution variable to the
2211 distributions file. It is used to conditionally add extra
2212 files or directories to the specific distribution. Affected
2213 files ./prepare, Makefile.am.pre and distributions.
2215 Removed the `_' from the start of the distribution names.
2218 * Added README.WIN32 for instructions to compile the Toolkit
2221 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Fixed a double free in disconnection in the server. Affected
2224 file is silcd/server.c.
2226 * Fixed the lib/silcske/groups.c to work now also with GMP
2227 MP library. The string conversion did not work when using
2228 specific base and the base is indicated in the string as well.
2230 * Created win32/ directory which now includes MSVC++ specific
2231 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2232 It will appear only in the toolkit distribution
2234 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Changed the key material distribution function in case when
2237 the hash output is too short. The data is now concatenated
2238 a bit differently than it used to. Made the change to the
2239 SKE protocol specification.
2241 * Added better GMP detection to configure.in.pre. A patch
2244 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Fixed a minor bug in SKE that might cause some problem on
2247 some platforms. Affected file lib/silcske/silcske.c.
2249 * Added the cookie checking for initiator in the SKE. It checks
2250 that the responder returns the sent cookie unmodified. The
2251 affected file is lib/silcske/silcske.c. Added new SKE
2252 error type INVALID_COOKIE that can be sent during the
2253 negotiation. Fixed some memory leaks as well.
2255 * Added the "invalid cookie" error message to Irssi SILC client's
2258 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Added `task_max' field to the SilcClientParams to indicate
2261 the maximum tasks the scheduler can handle. If set to zero,
2262 default values are used. Affected file lib/silcclient/silcapi.h.
2264 * Fixed memory leaks in silc_client_close_connection. Affected
2265 file lib/silcclient/client.c.
2267 * Added silc_client_del_client_entry to client library to free
2268 all memory of given client entry. Affected file is
2269 lib/silcclient/idlist.[ch].
2271 * Added new functions silc_client_del_channel and
2272 silc_client_del_server to delete channel and server entries.
2273 Affected file lib/silcclient/[silcapi.h/idlist.c].
2275 * Removed silc_client_del_client_by_id from silcapi.h.
2277 * Fixed the INFO command to return the server's own info
2278 correctly when querying by Server ID. Affected file is
2281 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2283 * Removed the non-blocking settings in WIN32 code in the
2284 silc_sock_[read/write] and added SleepEx instead. Affected
2285 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2286 of input data is now checked with FIONREAD and ioctlsocket.
2288 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2290 * Call silc_schedule_task_del_by_context in the
2291 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2292 Affected file lib/silccore/silcprotocol.c.
2294 * Call silc_protocol_cancel for active protocols in the
2295 silc_server_close_connection if the funtion
2296 silc_server_free_sock_user_data has not been called.
2297 Affected file silcd/server.c.
2299 * Generic tasks cannot be deleted using the del_by_fd
2300 task deleting function since generic tasks does not match
2301 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2303 * Added a notion to SILCOPER help file that the SILCOPER works
2304 only on router server, not on normal server.
2306 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Added for WIN32 support for the new scheduler as well.
2309 Affected file lib/silcutil/win32/silcwin32schedule.c.
2311 * Fixed the SHA1 implementation to work on various platforms.
2313 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2315 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2316 API. It is part of the scheduler now. Everything else is
2317 as previously but some functions has changed their names.
2318 Checkout the lib/silcutil/silcschedule.h for the interface.
2319 Updated all applications to use the new interface. Affected
2320 files are lib/silcutil/silcschedule.[ch].
2322 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2324 * Found a bug in the SKE implementation. The HASH value,
2325 specified by the protocol, was not computed correctly. The
2326 public key of the responder was not added to the computation
2327 even though it is mandatory. Affected file lib/silcske/silcske.c.
2328 This unfortunately causes incompatibilities with older
2329 clients and servers.
2331 * Added WIN32 specific network init and uninit functions:
2332 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2333 the Winsock2. Affected file lib/silcutil/silcnet.h and
2334 lib/silcutil/win32/silcwin32net.c.
2336 * Set the socket always to nonblocking mode on WIN32 after
2337 reading data or writing data. Affected file is
2338 lib/silcutil/win32/silcwin32sockconn.c.
2340 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2342 * Fixed various compilation problems under WIN32. Affected
2343 files lib/silcutil/win32/silcwin32thread.c and
2344 lib/silcutil/win32/silcwin32schedule.c.
2346 * Removed all _internal.h #includes from public header
2347 files. Internal headers must never be included from
2350 Removed also the lib/silcske/payload_internal.h file.
2352 * All include files that may be needed (public and some others
2353 included by the public headers) by application developers are
2354 now copied to the ./includes directory. It does not copy any
2355 internal headers. Affected file Makefile.defines.pre and all
2356 Makefile.am's under lib/ and subdirs.
2358 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * Do not change the ~/.silc directory's permissions automatically.
2361 Affected file irssi/src/silc/core/clientutil.c.
2363 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Do not cancel the protocol in silc_server_close_connection
2366 it might cause recursion. Now cancelled in the function
2367 silc_server_free_sock_user_data. Affected file silcd/server.c.
2369 * Fixed the silc_server_remove_clients_by_server to regenerate
2370 the channel keys correctly finally. Added also new function
2371 silc_server_remove_clients_channels to actually do it.
2372 Affected file silcd/server.c.
2374 * Fixed the silc_server_new_channel to not crash by giving
2375 wrong router to the new channel. Affected file is
2376 silcd/packet_receive.c.
2378 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2381 which is given as argument to the silc_client_alloc now.
2382 It can be used to configure the client and set various parameters
2383 that affect the function of the client.
2385 * The USERS command in server did not check whether the channel
2386 is private or secret. Affected file silcd/command.c.
2388 * Added new argument to the USERS command in protocol specification.
2389 The USERS command now can take the channel name as argument
2390 as well. Added support for this in client and server and
2391 updated the protocol specs.
2393 * Completed the GETKEY command in client. It can be now used
2394 to fetch also servers public key not only some clients.
2395 Affected files lib/silcclient/command[_reply].c.
2397 * Added silc_client_get_server to return server entry by the
2398 server name. Affected files lib/silcclient/silcapi.h and
2401 * Redefined the IDENTIFY command in protocol specification to be
2402 more generic. It now can be used to query information about
2403 any entity in the SILC Network, including clients, servers and
2404 channels. The query may be based either the entity's name
2405 or the ID. Added support for this in both client and server.
2407 Affected files silcd/command.c and lib/silcclient/command.c
2408 and command_reply.c.
2410 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2411 the _from_client and _from_server functions. Affected file
2414 * Added silc_client_get_channel_by_id_resolve to the file
2415 lib/silcclient/silcapi.h to resolve channel information by
2416 its ID. Added also silc_client_get_channel_by_id that
2417 does not resolve it from the server.
2419 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Added SilcServerEntry context into the client library
2422 to represent one server. The INFO command now allocates
2423 these to save the resolved server info. For now on the
2424 client library will also keep information about servers,
2425 connected and resolved with INFO.
2427 The INFO command now allocates the SilcServerEntry context
2428 and saves the server info there. The COMMAND_REPLY in
2429 the INFO now returns the parameters to application in
2430 same order as defined in the protocol specification.
2432 The entries are cached in the client->server_cache.
2434 * The INFO command is now issued after received the Client ID
2435 from the server. Affected file lib/silcclient/client.c.
2437 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2438 to the application as the mode changer might be server.
2439 It is guaranteed that NULL is not returned anymore to the
2440 application. Affected file lib/silcclient/client_notify.c.
2442 The ID Type is now also passed to the application so that
2443 it can check whether the returned entry is SilcClientEntry
2446 Added new function silc_client_get_server_by_id to return
2447 the server entry by ID. Affected files are the
2448 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2450 * Do not create the channel in the Irssi SILC Client when issuing
2451 the JOIN command but when received the sucessful JOIN command
2452 reply. Otherwise the channel might get created even though we
2453 could not join it. The Affected file is
2454 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2456 * Fixed a channel joining bug in router. The router must also
2457 check the channel modes, invite and ban lists etc. when serving
2458 the JOIN command sent by normal server. Affected file is
2459 silcd/command.c. The router now resolves the client's
2460 information from the server who sent the JOIN command if it
2461 does not know it, and processes the JOIN command only after
2464 * Changed the SilcCommandCb to take new argument; void *context2.
2465 Affected file lib/silccore/silccommand.h
2467 The second argument in the command callbacks in the server now
2468 includes the SilcServerCommandReplyContext if the command was
2469 called as pending command callback from the command reply.
2470 Otherwise it is NULL. When called as pending the status of the
2471 command reply will be checked and if it was erronous the
2472 error will be sent to the original sender of the command.
2473 This way the client always receives the error messages even
2474 though the server was actually the one who received the error
2475 when it resent the command to router, for example. Affected
2476 files silcd/command[_reply].[ch].
2478 * Fixed sending WHOWAS command's error message to client if
2479 the requested client could not be found. It was missing.
2482 * Changed the CMODE and CUMODE commands reply arguments in the
2483 protocol specification. The Channel ID is now sent in both
2484 of the commands to identify the channel. Implemented this
2485 new feature to the client and server. Affected files
2486 lib/silcclient/command_reply.c and silcd/command.c.
2488 * Made better checks for invite and ban lists in the JOIN
2489 command in server. Affected file silcd/command.c.
2491 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * The server now performs the incoming host IP/DNS lookup
2494 using the silc_socket_host_lookup and thus does not block
2495 the server anymore. Affected file silcd/server.c.
2497 * Completed the multi-thread support for SILC Scheduler in
2498 the lib/silcutil/silcschedule.c.
2500 * Fixed the configure.in.pre to detect the pthread correctly
2503 * Fixed a deadlock in silc_task_queue_wakeup in the file
2504 lib/silcutil/silctask.c.
2506 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Added new function silc_schedule_wakeup that is used in
2509 multi-threaded environment to wakeup the main thread's
2510 schduler. It needs to be used when a thread adds a new task
2511 or removes a task from task queues. After waking up, the
2512 scheduler will detect the task queue changes. If threads
2513 support is not compiled in this function has no effect.
2514 Implemented the wakeup mechanism to both Unix and WIN32
2515 systems. Affected files are lib/silcutil/silcschedule.[ch],
2516 lib/silcutil/unix/silcunixschedule.c and the
2517 lib/silcutil/win32/silcwin32schedule.c.
2519 * Added new function silc_task_queue_wakeup to wakeup the
2520 scheduler by the specified task queue. Affected file
2521 lib/silcutil/silctask.[ch].
2523 * The silc_socket_host_lookup_start now wakes up the scheduler
2524 after adding the timeout task. Affected file is
2525 lib/silcutil/silcsockconn.c.
2527 * The silc_socket_host_lookup is synchronous now if the threads
2528 support is not compiled in. However, the callback is still
2529 called asyncronously through the scheduler, anyway. Affected
2530 file lib/silcutil/silcsockconn.c.
2532 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2534 * Added new function silc_socket_host_lookup to perform
2535 asynchronous IP and FQDN lookups for the socket connection.
2536 Affected files lib/silcutil/silcsockconn.[ch].
2538 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2541 that may or may not compile the mutex support in.
2543 Changed the silc_mutex_alloc interface. It allocates the
2544 mutex now to the sent pointer and returns TRUE or FALSE.
2546 Affected file lib/silcutil/silcmutex.h.
2548 * Wrote the SILC Task Queue interface to support multi-threads.
2549 Affected file lib/silcutil/silctask.[ch].
2551 * Wrote the SILC Scheduler to support multi-threads. Affected
2552 file lib/silcutil/silcschedule.c.
2554 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2557 in lib/silcutil/win32/.
2559 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Defined SILC Mutex API and SILC Thread API and implemented
2562 them for Unix. Affected files are
2563 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2564 lib/silcutil/unix/silcunixmutex.c and
2565 lib/silcutil/unix/silcunixthread.c.
2567 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Fixed the silc_server_remove_clients_by_server's channel
2570 key re-generation. The hash table handling was incorrect
2571 and would not work with many channels. Affected file is
2574 * Fixed some memory leaks around the server code.
2576 * Rewrote the silc_server_get_users_on_channel to support IPv6
2577 based Client ID's. Affected file silcd/server.c.
2579 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2580 specification. However, a separate document must be written
2581 to define the detailed signing procedure and the payload
2582 associated with the flag. Defined the flag to the
2583 lib/silccore/silcchannel.h as well.
2585 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Changed the dynamic tables to static size tables in the
2588 lib/silccrypt/silchmac.c.
2590 * Removed GCC dependencies from the code. A patch by cras.
2592 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Do not show the error "Error receiving packet bla bla"
2595 in server if it really was not an error (-2 means that reading
2596 is pending). Affected file silcd/server.c.
2598 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Fixed a possible crash in silc_server_remove_clients_by_server
2601 in silcd/server.c. Fixed there also some memory leaks.
2603 * Fixed the silc_idlist_replace_client_id. It could replace
2604 wrong key in the hash table. Affected file silcd/idlist.c.
2606 * Do not check whether there are global users on the channel
2607 if the channel->global_users is FALSE. Affected functions
2608 silc_server_remove_from_one_channel and
2609 silc_server_remove_from_channels in silcd/server.c. Also,
2610 do not check if the removed client is local as we can be
2611 sure that global client was not removed from the channel
2612 and checking for global users is not needed.
2614 * The silc_server_remove_clients_by_server now re-generates
2615 the channel keys correctly for those channels that had
2616 clients removed from them. Affected file silcd/server.c.
2618 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Found the reason of random crashes in the server. We weren't
2621 ignoring the SIGPIPE signal (which can be sent in write())
2622 and it crashed the server. Affected file silcd/silcd.c.
2624 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Assure that sock->user_data is not NULL in the function
2627 silc_server_packet_send in silcd/packet_send.c.
2629 * Disconnect the remote connection if it could not be added
2630 to any ID lists in the server. The affected file is
2633 * Check in silc_server_packet_send[_real/dest] that the
2634 socket is not disconnecting and ignore the data if it is.
2635 Affected file silcd/packet_send.c.
2637 * Define inline to __inline on native WIN32 compilation.
2638 Affected file includes/silcwin32.h.
2640 * Added some explicit type casts for inline code since MSVC
2641 require them. Affected files lib/silcutil/silcbuffer.h,
2642 lib/trq/silcdlist.h and lib/trq/silclist.h.
2644 * Print warning in log files from now on if the packet
2645 decryption fails. Affected file silcd/server.c.
2647 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2649 * Changed the `say' client operation's interface to accept
2650 new `type' argument to indicate the type of the message sent
2651 by the library. The application may filter the library's
2652 messages according the type. The affected file is the
2653 lib/silcclient/silcapi.h.
2655 * Added two new functions to lib/silcclient/silcapi.h:
2656 silc_client_del_client and silc_client_del_client_by_id.
2657 Affected file lib/silcclient/idlist.c.
2659 * Moved the clientincludes.h from includes/ to silc/ and
2660 serverincludes.h from includes/ to silcd/.
2662 * The modes for the CMODE and CUMODE are now passed as
2663 uint32 for application with COMMAND_REPLY. The affected
2664 file is lib/silcclient/command_reply.c.
2666 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * /WHOIS without arguments shows client's own information.
2669 Affected file lib/silcclient/command.c.
2671 * Changed PING to not accept any arguments. The specs
2672 says that client can ping only the connected server so
2673 requiring an argument is not needed. Affected file is
2674 lib/silcclient/command.c.
2676 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed a fatal bug in private message sending and reception
2679 encryption and decryption when using private message keys.
2680 The implementation was incorrect and did not follow the
2681 specification. It causd that some of the message were
2682 lost since it did not use the sending and receiving keys
2683 as the protocol suggests. This has been fixed and will cause
2684 incompatibilities with older clients when sending private
2685 message encrypted with private message keys. Affected files
2686 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2687 and various other in Irssi SILC Client.
2689 Added `responder' boolean argument to the functions
2690 silc_client_add_private_message_key[_ske] to indicate when
2691 the key is added as responder or initiator of the key
2694 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Removed the silc_ske_check_version function and created
2697 a SilcSKECheckVersion callback. Added also a function
2698 silc_ske_set_callbacks that is now used to set all SKE
2699 callbacks. The callback functions are not given to
2700 the SKE functions anymore, but this function is used to
2703 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2705 * Added `silc_version' argument to the silc_client_alloc
2706 to define the version of the application for the library.
2707 The library will use the version string to compare it
2708 against the remote host's (usually a server) version
2709 string. Affected file lib/silcclient/silcapi.h
2711 * Added the KE protocol context to Key Agreement context
2712 in client library so that we can abort the SKE if it
2713 is in process when we get timeout. Affected file is
2714 lib/silcclient/client_keyagr.c.
2716 * Do not resolve the client ID forever if it returns in the
2717 first time that such client does not exist. This was done
2718 for example with private message. Affected file is
2719 lib/silcclient/client_prvmsg.c.
2721 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2723 * Do not add regex.h for WIN32. The affected file
2724 includes/silcincludes.h.
2726 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2727 not work yet 100%. It generates the DLL's automatically
2728 when compiling with --with-win32 under cygwin.
2730 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * lib/contrib/regex.c is not compiled on WIN32.
2734 * Added silc_net_get_socket_opt function to the
2735 lib/silcutil/silcnet.h.
2737 * Added includes/silcwin32.h for WIN32 specific includes
2740 * Do not use ptime structure or any of the posix process
2741 functions on WIN32 in lib/silccrypt/silrng.c.
2743 * Added silc_gettimeofday to provide generic function
2744 for struct timeval on all platforms. Added the function
2745 to lib/silcutil/silcutil.h.
2747 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2749 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2750 library as they clearly belong there. As a plus side we
2751 can make the actual socket connection routines platform
2754 Added also new generic function silc_socket_read and
2755 silc_socket_write (that used to be silc_packet_[read/write].
2756 The implementation of these are platform specific.
2758 * Added WIN32 specific routines of silc_socket_[read/write]
2759 to lib/silcutil/win32/silcwin32sockconn.c.
2761 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Added preliminary support for native WIN32 compilation under
2764 cygwin (using the -mno-cygwin option for GCC) to the
2765 ./configure.in.pre. The --with-win32 now prepares the
2766 compilation for native WIN32.
2768 * Rewrote the SILC Scheduler interface in the file
2769 lib/silcutil/silcschedule.h. The scheduler is now context
2770 based and does not have anymore any global static scheduler.
2771 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2772 and created lib/silcutil/win32 directory for WIN32 based
2775 * Added Unix specific network routines to the
2776 lib/silcutil/unix/silcunixnet.c and the old
2777 lib/silcutil/silcnet.c includes now only generic routines.
2779 Added WIN32 specific network routines to the
2780 lib/silcutil/win32/silcwin32net.c.
2782 * Added Unix specific utility functions from the
2783 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2785 * Added WIN32 SILC Scheduler to the file
2786 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2789 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Do not handle JOIN notify in the server if the target client
2792 is not registered (idata->registered == FALSE). The affected
2793 file is silcd/packet_receive.c.
2795 * Update the nickrec->founder in event_cumode in the Irssi SILC
2796 client. Affected file irssi/src/silc/core/silc-channels.c.
2798 * Fixed the CUMODE_CHANGE notify handling in the server when
2799 server and router are announcing their clients on channels.
2800 Now the mode changes are saved and notified correctly. The
2801 affected file is /silcd/packet_receive.c.
2803 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2804 They really did not replace the cache entry in the ID Cache.
2805 Now they do that. Affected file silcd/idlist.c.
2807 * Fixed the KICK notify handling in the Irssi SILC client to
2808 update the channel records so that the kicked client does not
2809 appear to be on the channel. The affected file is
2810 irssi/src/silc/core/silc-channels.c.
2812 * Always update the conn->current_channel when executing command
2813 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2815 * Fixed the KILL notify handling in Irssi SILC client to remove
2816 the killed client on all channels.
2818 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2820 * Fixed the silc_parse_command_line to remove extra spaces
2821 from the start and end of the arguments. Affected file is
2822 lib/silcutil/silcutil.c.
2824 * Cancel and free any active protocol in the function
2825 silc_server_close_connection. Affected file silcd/server.c.
2827 * Cancel and free any active protocol in the function
2828 silc_client_close_connction. Affected file is
2829 lib/silcclient/client.c.
2831 * Do not execute the KILL command for clients that are in
2832 history (ie. they are not in the network). Affected file is
2835 * Fixed KILL notify handling, client does not crash anymore.
2836 Affected file irssi/src/silc/core/silc-channels.c.
2838 * Reduced the default packet buffer size from 2048 to 1024 in
2839 lib/silccore/silcpacket.c.
2841 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2842 counter to the SKE context that is incresed when the SKE library
2843 performs async operation outside the library. If the outside
2844 process frees the SKE context and FREED status will be set
2845 and the library will detect after the sync operation that the
2846 libary is freed. The affected files are
2847 lib/silcske/silcske[_status].[ch].
2849 * Resolve the client entry information in the function
2850 silc_client_channel_message to assure that NULL pointer is not
2851 passed as client entry to the application. */
2853 * Fixed the task timeout calculation to assure that there is
2854 never negative timeouts. The affected file is
2855 lib/silcutil/silcschedule.c.
2857 * Fixed the channel user mode notification sending in server.
2858 It was sent point-to-point to the router (or to server by router)
2859 but it needs to be destined to a channel. The routines now
2860 supports sending the channel user mode notifys to the channels
2861 when announcing clients and channels. Affected files are
2862 silcd/server.c and silcd/packet_receive.c.
2864 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2865 It did not actually replace the old channel entry in the cache.
2866 Affected file lib/silcclient/client_notify.c.
2868 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Fixed a possible crash in silc_packet_send_prepare. It now
2871 assures always that there is enough space in the buffer and
2872 at the tail area of the buffer (for MAC).
2874 Fixed the inbound buffer reallocation in silc_packet_read.
2875 It was old code and did not handle the reallocation correctly.
2878 The affected file is lib/silccore/silcpacket.c.
2880 * Fixed buffer overflow in silc_parse_nickname in the file
2881 lib/silcutil/silcutil.c.
2883 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2885 * make install generates new server keys only if there is not
2888 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2890 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2891 Added check that if the NOREPLY is set then we will not send
2892 the away message. This avoids infinite loop of away messages
2893 if both clients are away. The affected file is
2894 lib/silcclient/client_prvmsg.c.
2896 * Fixed client crash if /NICK was given without arguments.
2897 Affected file lib/silcclient/command.c.
2899 * Server does not send the invite list in INVITE command back
2900 to the client if the list was not altered. Added this notion
2901 to the protocol spec as well. Affected file silcd/command.c.
2903 Fixed possible crash in INVITE command by checking the
2904 value of silc_server_get_client_route command.
2906 * Fixed the INVITE notify type handling. The arguments are now
2907 taken in correct order and client does not crash. The affected
2908 file is irssi/src/silc/core/silc-channels.c.
2910 Removed the "Inviting xxx to channel" message from the
2911 client library away and let the application handle it.
2912 Affected file lib/silcclient/command.c. Added that message
2913 to Irssi SILC client's message formats.
2915 * Fixed CMODE command crash in client. It now checks the
2916 amount of arguments correctly and does not crash. The affected
2917 file is lib/silcclient/command.c.
2919 * Do not create new channel automatically in silc_channels_join
2920 but check whether the channel by that name already exists.
2921 Affected file irssi/silc/core/silc-channels.c.
2923 * Do not send the SERVER_SIGNOFF to router if the disconnected
2924 entity was the router. Affected file silcd/server.c.
2926 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2927 SILC client as it was missing from there.
2929 Added the handling of the KICK notify to the Irssi SILC client
2930 as it was missing. Added "you have been kicked" message to
2931 Irssi SILC client's message modules formats.
2933 Added the handing of the KILL notify to the Irssi SILC client
2934 as it was missing. Added the kill message module formats
2937 The affected file is irssi/src/silc/core/silc-channels.c.
2939 * The router did not save the channel mode the server announced.
2940 Affected file silcd/packet_receive.c.
2942 * Fixed a possible crash in INFO command in server. If the
2943 server did not provide the server info it crashed. Affected
2944 file silcd/command.c.
2946 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Fixed the GETKEY command in the server to check also the
2949 global list. Otherwise the GETKEY would not work correctly
2950 in normal SILC server. Affected file silcd/command.c.
2952 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Fixed GETKEY crash, it crashed if the command did not succseed.
2956 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2958 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2959 is now real and not just an macro interface to GMP.
2961 Removed the entire GMP from the source tree and imported new
2962 NSS MPI library instead. Reason for removing GMP is that it is
2963 extremely large and compiles extremely slow. The NSS MPI
2964 is only a few files and compiles in less than 10 seconds.
2965 The speed is also about the same as GMP. The MPI is imported
2966 to lib/silcmath/mpi.
2968 If the system has GMP installed we will still use the GMP.
2969 If it is not then the NSS MPI will be compiled.
2971 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Merged a long nickname (127 characters long) crash bugfix from
2974 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2976 * Merged a freed memory reference bugfix from Irssi CVS tree.
2977 Affected file irssi/src/core/commands.c.
2979 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added the server's public key sving and verification to the
2982 server when performing the SKE. This was missing and the
2983 remote server's (or router's) public key was accepted without
2984 checking whether we have it previously or trust it at all.
2985 Affected file silcd/protocol.c.
2987 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Check in the silc_server_timeout_remote if protocol is active
2990 and make sure that the protocol's final callback is called so
2991 that all memory if freed. Affected file silcd/server.c.
2993 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * silc_server_whois_send_reply crashed the server if the nickname
2996 was 127 characters long. Affected file silcd/command.c.
2998 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Added sanity check to the silc_server_new_client. If the hostname
3001 is provided inside username then check that the provided hostname
3002 really is the same as the resolved one. If the hostname was not
3003 resolved then check it from the public key. Affected file is
3004 silcd/packet_receive.c.
3006 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3007 if the server disconnected us and the connection is not valid
3008 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3010 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3011 the library to the lib/silcutil/silcutil.[ch].
3013 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Close log file after open. Affected file
3016 lib/silcutil/silclog.c.
3018 * Check whether sock == NULL in silc_client_send_packet and return
3019 if it is. Affected file lib/silcclient/silcclient.c.
3021 * Check rec->entry == NULL in the Irssi SILC Client before
3022 sending the channel message. Affecte file is
3023 irssi/src/silc/core/silc-servers.c.
3025 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Merged a splitted window bugfix from Irssi CVS tree. The
3028 affected file is irssi/src/fe-text/textbuffer-view.c.
3030 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3031 It did not print nickname.
3033 * Improved the distributions system a bit.
3035 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3037 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3038 irssi/src/fe-text/gui-window.c.
3040 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3041 to in-active server. The affected file is
3042 irssi/src/silc/core/client_ops.c.
3044 * Resolve the client in USERS command reply if the entry does
3045 not have username resolved. The affected file is
3046 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3047 command to WHOIS command to really resolve stuff. The USERS
3048 is not used any more in any critical section so WHOIS can
3049 be used even though it might be slower than IDENTIFY.
3051 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3054 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Changed the protocol API a bit more consistent in the
3057 lib/silccore/silcprotocol.[ch].
3059 * Changed the following headers to ROBODoc format:
3061 lib/silccore/silcpayload.h
3062 lib/silccore/silcprotocol.h
3063 lib/silccore/silcsockconn.h
3065 All core library headers are now formatted.
3067 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Fixed a bug in Irssi SILC client; do not show that you are
3070 server/router operator if you really are not. Affected file is
3071 irssi/src/silc/core/client_ops.c.
3073 * Renamed silc_command_free_payload to silc_command_payload_free.
3074 Affected file lib/silccore/silccommand.h
3076 * Added silcmath.h to include the prototoypes of various routines
3077 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3080 * Changed the following headers to ROBODoc format:
3082 lib/silccore/silcchannel.h
3083 lib/silccore/silccommand.h
3084 lib/silccore/silcid.h
3085 lib/silccore/silcidcache.h
3086 lib/silccore/silcmode.h
3087 lib/silccore/silcnotify.h
3088 lib/silccore/silcpacket.h
3089 lib/silcmath/silcmath.h
3091 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3093 * Added checking to the server code not to start the server if
3094 ciphers and stuff are not configured properly. Affected files
3095 silcd/serverconfig.[h] and silcd/server.c.
3097 * Changed the layout of the header files of the public interfaces
3098 in the SILC libraries. The new layout supports ROBODoc
3099 documentation tool (and some others) so that it is easy to create
3100 a library reference manual. All the other headers and source
3101 code must still follow the CodingStyle document. Also source
3102 code must not include these ROBODoc stuffs, only the headers.
3103 Furthermore, all public interface headers must now be named
3104 by using `silc' prefix, example: silcapi.h, silccipher.h.
3105 Some files were renamed due to this. All the other headers
3106 must not be used as public interfaces. I will update the
3107 CodingStyle document later. Changed following headers, so far:
3109 lib/silcclient/silcapi.h
3110 lib/silccore/silcauth.h
3111 lib/silccore/silcprivate.h
3112 lib/silccrypt/silcdh.h
3114 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Removed silc_client_packet_send_flush from the client library
3119 as it is not needed. Affected file lib/silcclient/client.[ch].
3121 * Added printing of message of unresolved authentication method
3122 to the Irssi SILC client. Added it to the module formats.
3123 Removed the same message from the client library.
3125 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Added new distribution feature, DISTLABEL. Every distribution
3128 can define own preprocessor label that can be used in the
3129 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3130 file distributions, acconfig.h.pre and prepare.
3132 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Added Makefile.defines_int to include the actual definitions
3135 for Makefile.defines.in. Tested the new distribution system,
3136 created distributions and tested installation.
3138 * Added AWAY message printing to the Irssi SILC client. Added
3139 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3141 * Added SCONNECT command to call the SILC's CONNECT command.
3142 Cannot use CONNECT directly since Irssi uses that internally.
3143 Affected file irssi/src/silc/core/silc-servers.c.
3145 Added ACTION local command. It is same as ME command but takes
3146 the channel as mandatory argument.
3148 Rewrote some of the Irssi's help files to suite for SILC
3151 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Added Makefile.defines[.in] that should for now on be included
3154 in all Makefile.am file in the source tree. That file includes
3155 all common compilation definitions for SILC source tree.
3157 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Minor changes to the ./prepare script to change the package
3160 name according the distribution name to the configure.in.
3162 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Created new distribution system. Added file `distributions'
3165 that defines all the distributions that can be created out of
3166 the SILC source tree. The ./prepare script now reads that
3167 file to determine how to prepare the distributions. The
3168 first argument to the ./prepare is the name of the distribution
3169 and second is the version of the distribution. If given
3170 without arguments it creates the default (toolkit) distribution
3171 with the default version (defined in ./prepare).
3173 All Makefile.am files that are subject to the distributions
3174 are now named as Makefile.am.pre. These are ./Makefile.am
3175 and lib/Makefile.am. Others may be changed later.
3177 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Added invite list, ban list, some key management and connection
3180 error message printing to module formats in the Irssi SILC client.
3182 * Added new silc_client_set_away_message to set the away message
3183 that is back to the person who sent private message. The
3184 affected file lib/silcclient/silcapi.h and the
3185 lib/silcclient/client_prvmsg.c.
3187 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Fixed the private message sending in the Irssi SILC client,
3190 added local command KEY to the Irssi SILC client.
3192 Added key management and key agreement message formats to the
3193 irssi/src/fe-common/silc/module-formats.[ch].
3195 Added USERS (alias WHO) printing, server/router operator
3196 indication and LIST command printing to the module formats.
3198 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Fixed channel joining notify handling, cumode notify handling
3201 from Irssi SILC client.
3203 * Added SILC specific module-formats to the Irssi SILC client so
3204 that SILC specific message hilighting, colors etc is possible.
3205 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3207 Added channel mode, channel user mode, actions, notices,
3208 whois and whowas printing to the the module-formats.c.
3210 * Fixed a bug in channel deletion in the server. The channel
3211 is not left to the cache even if the channel founder auth mode
3212 is set when there are no users anymore on the channel. Affected
3213 file silcd/server.c.
3215 * The silc_net_localhost now resolves the entire hostname including
3216 the domain name. Affected file lib/silcutil/silcnet.c.
3218 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Changed the ask_passphrase client operation to be ascynchronous.
3221 It has now a completion callback and a context that the
3222 application must call after it has got the passphrase from
3223 the user. Affected files lib/silcclient/silcapi.h,
3224 lib/silcclient/protocol.c, lib/silcclient/command.c and
3227 Added SilcAskPassphrase callback that the application calls
3228 to deliver the passphrase to the library.
3230 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3231 The public key verification and especially a certificate
3232 verification is asynchronous procedure.
3234 Added new SILC_SKE_STATUS_PENDING status to indicate the
3235 request is pending and a callback will be called to finalize
3238 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3239 indicate that remote end did not send its public key (or
3240 certificate), even though we require it. Added check for this
3241 condition in the SKE. This was a security bug, now fixed.
3243 Defined new SilcSKEVerifyCbCompletion callback that is called
3244 when the verification process is completed.
3246 The affected files lib/silcske/silcske_status.h and
3247 lib/silcske/silcske.[ch].
3249 * Changed the verify_public_key client operation to be async
3250 as well. Defined SilcVerifyPublicKey callback that is used to
3251 indicate the success of the public key verification process.
3253 Changed the server and client to use the new async client
3256 * Changed the Irssi SILC client's internal scheduler to be called
3257 twice as many times as it used to be. As a result the client
3258 should be a bit faster now. Affected file is
3259 irssi/src/silc/core/silc-core.c.
3261 * Added support to Irssi SILC client of asynchronous public key
3262 verification and passphrase inquiry. Affected file is
3263 irssi/src/silc/core/silc-core.c.
3265 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Do not say "You have left channel %s" in client library.
3268 Moved it to the application. Affected files are
3269 lib/silcclient/command.c and silc/client_ops.c.
3271 * Fixed silc_client_get_clients. Command context was not
3272 duplicated and was freed memory in the callback. Affected
3273 file lib/silcclient/idlist.c.
3275 * Do not say "you are now talking..." on JOIN command in the
3276 client library. The appliation must handle it.
3278 * Do not say ".. changed topic to" in command reply in the
3279 client libary. The application must handle it.
3281 * Fixed TOPIC command sending in the client library.
3283 * Fixed a memory leak in silc_client_command_free in the file
3284 lib/silcclient/command.c.
3286 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Imported a modified version of Irssi client to the source tree.
3289 The Irssi will be used to create a new client called
3290 Irssi SILC. Imported to irssi/.
3292 Added silc_core_init_finish function to the Irssi. Affected
3293 file irssi/configure.in.
3295 A lot changes in the Makefile.ams around the irssi tree.
3297 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Do not rehash if the new size is same as the old size of the
3300 hash table, in the silc_hash_table_rehash*. The affected file
3301 lib/silcutil/silchashtable.c.
3303 * Replaced hash_table_del_by_context calls from the server
3304 (when channel->user_list and client->channels) to the
3305 hash_table_del as it is sufficient and faster.
3307 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Added silc_hash_table_list, silc_hash_table_get and the
3310 SilcHashTableList structure to provide an alternative way to
3311 traverse the hash table. The affected files are
3312 lib/silcutil/silchashtable.[ch].
3314 * Changed the server's idlist routines to use the hash table
3315 routines to optimize the code.
3317 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Replaced the client entry's `channel' list and channel entry's
3320 `user_list' list to hash tables for optimized lookup. Changed
3321 the code to use the hash table interface around the code.
3322 Affected file lib/silcd/idlist.[ch].
3324 * Added `auto_rehash' boolean argument to the function
3325 silc_hash_table_alloc to indicate whether the hash table should
3326 auto-rehash when it thinks is appropriate time. It will
3327 increase the hash table size if the there is twice as much
3328 entries in the table than the size of the table, and will
3329 decrease the size if there are twice as less entries than
3330 the size of the table.
3332 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3336 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3338 * silc_idcache_purge_by_context deletes the entry now by context
3339 as it is supposed to do. Affected file lib/silccore/idcache.c.
3341 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3342 client is not anymore valid (WHOWAS givens the info) and not
3343 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3345 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Removed the `data' and `data_len' arguments from the ID Cache
3348 interfaces and added `name' argument. ID Cache does not handle
3349 anymore the binary data only a names associated with given ID.
3351 * When hashing a Client ID with silc_hash_id the entire ID is
3352 not hashed anymore, instead only the hash of the Client ID is
3353 hashed. This way we can access the Client ID from the cache
3354 with Client ID but with the hash of the ID (which is a hash of
3355 the nickname) as well without any difference in performance.
3357 Added also silc_idcache_find_by_id_one_ext to do one on one
3358 searching when we have the actual ID. Added also function
3359 silc_hash_client_id_compare. The affected files are
3360 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3362 * When hashing the name associated with a ID it is always done
3363 in lowercase. This way we can access the cache without worrying
3364 about case-sensitivity, even though, for example nicknames are
3367 * Fixed a bug in server with channel message sending. It put
3368 wrong ID type as destination ID. The affected file
3369 silcd/packet_send.c.
3371 * silc_idcache_del_by_context now deletes from all hash tables
3372 by context. Affected file lib/silccore/idcache.c.
3374 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Changed the client library to use the new ID Cache interface.
3377 Changes around the source tree.
3379 * Added silc_hash_table_rehash_ext to rehash with specific
3380 hash function. Affected file lib/silcutil/silchashtable.[ch].
3382 * Added silc_hash_string_compare to compare two strings in the
3383 hash table. Affected file lib/silcutil/silcutil.[ch].
3385 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Added new function silc_idcache_del_by_context into the
3388 lib/silccore/idcache.[ch].
3390 * Changed the server's ID list routines to use the new ID Cache
3391 interface. Changes around the source tree.
3393 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Added silc_hash_table_del[_by_context]_ext functions in to the
3396 lib/silcutil/silchashtable.[ch].
3398 Removed silc_hash_table_find_all* routines and added new
3399 silc_hash_table_find_foreach to replace them.
3401 Added silc_hash_table_replace_ext function as extended
3402 replacing function. Separated the simple hash table interface
3403 from the extended hash table interface in the file
3404 lib/silcutil/silchashtable.h.
3406 * Fixed minor bugs and changed it to use some of the new
3407 hash table functions in lib/silccore/idcache.c
3409 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Added new function silc_hash_table_find_all to return all keys
3412 in the hash table by the specified key. As the hash table is
3413 collision resistant it also makes it possible to have several
3414 duplicate keys in the hash table. This function may be used to
3415 find all of the keys from the hash.
3417 Added user_context arguments to the SilcHashFunction,
3418 SilcHashCompare and SilcHashDestructor to deliver user specified
3421 Added new fuctions silc_hash_table_find[_all]_ext to do
3422 extended lookup with specified hash and compare functions and
3423 specified user contexts.
3425 Added new function silc_hash_table_add_ext to add the key
3426 with specified hash function and user context.
3428 Added new function silc_hash_table_foreach to traverse all
3429 entrys in the hash table. Added SilcHashForeach callback
3432 Added new function silc_hash_table_del_by_context to delete
3433 the entry only if the context associated with the key matches.
3435 Affected files are lib/silcutil/silchashtable.[ch].
3437 * Removed silc_hash_[server/client/channel]_id and added just
3438 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3439 silc_hash_id_compare to compare two ID's using as the hash table
3440 comparison function. Added also silc_hash_data to hash
3441 binary data and silc_hash_data_compare to compare it.
3443 * Removed silc_idlist_find_client_by_hash as it is not needed
3444 anymore. Affected file silcd/idlist.[ch].
3446 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3447 to use internally the SilcHashTable. The new ID Cache is a lot
3448 faster than the old one. Some of the ID Cache interface was also
3449 rewritten and obsolete and stupid functions were removed.
3451 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Added entry_count field to the SilcHashTable to keep the number
3454 of the entries in the table. Implemented the function
3455 silc_hash_table_rehash. Added new function
3456 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3458 Fixed a minor bug in silc_hash_table_free.
3460 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3461 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3462 into the lib/silcutil/silcutil.[ch].
3464 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Implemented a collision resistant hash table into the
3467 lib/silcutil/silchashtable[ch]. See the header and the source
3468 for the SilcHashTable API.
3470 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Merged dotconf version 1.0.2 into lib/dotconf.
3474 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Do not compile anything in lib/silcsim/* if the SIM support
3477 is not enabled. The tree should now compile without problems
3480 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Compiled the SILC under cygwin. Compiled and tested briefly
3483 without problems. More tests needed. The SIMs didn't compile
3486 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3488 * Fixed possible crash in silc_get_username in the
3489 lib/silcutil/silcutil.c.
3491 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Fixed a va_arg in silc/client_ops.c.
3495 * Oops, RC5 routines were named AES and caused some problems
3496 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3498 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Added new SilcIDIP structure into the lib/silccore/id.h and
3501 replaced the old `ip' fields from all SILC ID's to that type.
3502 This is a step towards IPv6 support.
3504 The silc_id_get_len takes now the ID as an extra argument.
3505 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3506 both IPv4 and IPv6 based ID's.
3508 The affected files are lib/silccore/id.[ch] and other files
3509 around the tree using these routines.
3511 * Removed the ID length arguments in server from various
3512 silc_server_send_notify_* routines -> they are not needed
3515 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * Fixed memory leak in silc_encode_pem_file in the file
3518 lib/silcutil/silcutil.c.
3520 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Check minor version as well in the SKE. Affected files are
3523 silcd/protocol.c and lib/silcclient/protocol.c.
3525 * Added --identifier option to the server so that an identifier
3526 can be when creating the public key for the server. Affected
3527 file is silcd/silcd.c.
3529 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3530 lib/silccrypt/silcpkcs.c.
3532 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Register default ciphers and stuff when using -C option with
3535 the server. Affected file sildc/silcd.c.
3537 * Put back the servers public key filename format, it is better
3538 than the new one. For now, the client keys are saved with the
3539 new filename format. The affected file silc/client_ops.c.
3541 * Implemented the Cipher API for the rest of the ciphers that
3542 did not implement it or implemented it the wrong way.
3544 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * Register default ciphers and stuff when using the -S option
3547 in the client. Affected file silc/silc.c. Same also when
3548 creating new key pair with -C option.
3550 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Fixed the silc_verify_public_key client operation function to
3553 save the public keys differently. The fingerprint is now
3554 used as filename and not the hostname. This way also the
3555 client keys are saved uniquely and not with hostnames. The
3556 affected file is silc/client_ops.c.
3558 * Trimmed the silc_hash_fingerprint function to remove extra
3559 whitespaces from the end of the fingerprint. The affected
3560 file is lib/silccrypt/silchash.c.
3564 * Added silc_cipher_register_default function to register all
3565 default ciphers. It can be used when configuration files
3566 does not exist and the application does not want any specific
3567 ciphers in any specific order.
3569 The SilcDList is now used as silc_cipher_list dynamically
3570 allocated cipher list. Removed the static list all together
3571 and now all ciphers must be allocated to the dynamic list.
3572 The silc_cipher_alloc routine was changed to check only the
3575 All silc_cipher_* routines that used to return int returns
3578 The affected files lib/silccrypt/silccrypt.[ch].
3580 * The same thing was done to silc_hash_* as for silc_cipher_*
3581 routines. Affected files lib/silccrypt/silchash.[ch].
3583 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3584 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3585 Added also silc_pkcs_[un]register[_default] functions.
3586 Removed the data_context from the PKCS API.
3588 * Added silc_hmac_register_default function to register default
3589 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3590 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3591 to unregister all hmacs at once.
3593 * Register the default ciphers, hash functions, PKCSs and HMACs
3594 if client's configuration file does not exist. The affected
3597 * The client did not load the hash functions from the SIM
3598 modules at all. Added support for this. Affected file is
3599 silc/clientconfig.c.
3601 * When decoding public key with silc_pkcs_public_key_decode, check
3602 the supported algorithm only if PKCS are registered. Affected
3603 file lib/silccrypt/silcpkcs.c. The same was done with the
3604 silc_pkcs_private_key_decode.
3606 * Fixed the SILC List routines to keep the list always in order.
3607 It used to change the list's order when traversing the list but
3608 not it preserves the order. Affected file lib/trq/silclist.h.
3610 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Added the client library to use the SilcSocketConnection's
3613 reference counter (by silc_socket_dup) to prevent the bug that
3614 the socket object may be freed underneath async operation.
3616 * The name resolv library checking fixes in the configure.in.pre.
3619 * Created new version of the protocol drafts for future
3620 development. The -03 drafts are the ones that will be changed
3621 in the trunk now and the -02 will remain as they are.
3623 * Send list of CUMODE notifys to the router when announcing
3624 the channel users to the router. Affected file silcd/server.c.
3625 If the router receiving channel founder CUMODE for a channel
3626 that already has channel founder it will send CUMODE notify
3627 to the sender to remove the channel founder rights from the
3628 announced client. Affected file silcd/packet_receive.c.
3630 * The CUMODE notify may now use Server ID as well as the entity
3631 who changes the mode. Updated protocool specs.
3633 * Updated INSTALL and README files.
3635 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * New web pages in the http://silc.pspt.fi. The pages was
3642 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Implemented the [DenyConnectin] config section in the server.
3645 Added silc_server_config_denied_conn to check whether incoming
3646 connection is denied. Affected file silcd/serverconfig.[ch].
3648 * Do not check the ports when checking the incoming configuration
3649 data if the port is 0, meaning any. Affected file is
3650 silcd/serverconfig.c.
3652 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Fixed buffer overflow in silc_string_compare in the file
3655 lib/silcutil/silcutil.c.
3657 * Fixed double free in silc_server_command_leave in the file
3660 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Fixed the version checking in the server. Affected file is
3665 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Fixed the configuration data fetching when accepting new
3668 connections in the server. Affected file silcd/server.c.
3670 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added `sender_entry' argument to the function
3673 silc_server_packet_relay_to_channel so that we can check
3674 whether some destination actually belongs to the same route
3675 the sender belongs (ie, we must not resend the packet to the
3676 sender). Affected file silcd/packet_send.[ch].
3678 * Added `servername' field to the SilcClientEntry in the server
3679 to hold the name of the server where client is from. Affected
3680 file is silcd/idlist.h.
3682 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Moved the channel message encrypting in the router betwen
3685 router connections from silc_server_channel_message to the
3686 silc_server_packet_relay_to_channel since we want to check
3687 whether we have anybody channel before encrypting anything.
3688 Affected files silcd/packet_[receive/send].c.
3690 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3692 * Fixed the [AdminConnection] server config section to support
3693 multiple entries. Affected file silcd/serverconfig.c.
3695 * Added support into the server to check the validity of the
3696 incoming connection before executing any KE or authentication
3699 * The connection configuration is now saved to the KE and
3700 connection auth protocol contexts and not fetched anymore in
3701 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3703 * The local hosts listenning address and port is also resolved
3704 now when starting the server. We want to have the socket object
3705 to include the real address and port for the listener. Added
3706 new function silc_net_check_local_by_sock into the files
3707 lib/silcutil/silcnet.[ch].
3709 * Fixed a broadcast bug in server -> do not broadcast if we
3712 * Fixed a routing bug. Do not route broadcast packets ever.
3713 Broadcast packets must be processed always and not routed since
3714 they may be destined to some other host than yourself and thus
3715 would get routed without no good reason. Affected file is
3718 * Added function silc_server_config_is_primary_route to check
3719 whether primary router connection has been configured (a router
3720 configuration that we are initiating). If there is not, we
3721 will assume that there is only two routers in the SILC network
3722 and we will use the incoming router connection as our primary
3723 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3725 * Changed the order of the broadcasting. Broadcast _after_ the
3726 packet has been processed not before. Affected file is
3729 * Fixed a [ClientConnection] parsing bug. The port was never
3730 parsed correctly thus resulting to port 0. Affected file
3731 silcd/serverconfig.c.
3733 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3734 argument and did not set the broadcast packet flag. Affected
3735 file silcd/packet_send.c. Fixed same bug in the function
3736 silc_server_send_notify as well.
3738 * If we receive NEW_ID packet for our own ID in the server, ignore
3741 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Removed the nickname from the Private Message Payload.
3746 Updated the code and the protocol specs.
3748 * Updated protocol specs for submitting to the IETF.
3750 * Tweaked the Random Number Generator a bit. Affected file
3751 lib/silccrypt/silcrng.c. Exported a new function
3752 silc_rng_[global]_add_noise which can be used to add more
3755 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Do not parse packets with different timeout when protocol
3758 is active -> may cause problem with rekey. Affected file
3761 * When server receives signoff notify it must not create
3762 new channel key if the client is on any channels since the
3763 sender of the signoff notify will create it.
3765 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Added printing of error messages during SKE protocol from the
3768 failure packet sent by server during SKE. Affected file
3771 * Removed the client's failure_callback handling with timeout
3772 and handle it immediately when received.
3774 * The SKE library returned wrong type in SUCCESS and FAILURE
3775 packets. They must be 32 bit MSB not 16 bit MSB.
3777 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Ok, rewrote the logic of the re-key and now it seems to work.
3780 I tested it on high traffic with frequent re-keys without
3781 problems. Added hmac_receive (and renamed hmac to hmac_send)
3782 in SilcClientConnection in lib/silcclient/client.h and
3783 in SilcIDListData in silcd/idlist.h. Also, removed the
3784 SilcPacketParserContext's cipher and hmac fields as they are
3785 not needed anymore and actually caused some problems when
3786 the ciphers and hmac's changed underneath the packet parser.
3788 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * If re-key protocol is active then process the incoming packets
3791 synchronously since we must assure that icoming packets encrypted
3792 with the old key is processed before the new keys is set to
3793 use. This is true other packets than for REKEY packets.
3794 Affected file silcd/server.c. The same was done to client library
3795 as well, affected file lib/silcclient/client.c.
3797 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Fixed bug in client and server to accept the force send if
3800 the packet is send from silc_[server/client]_packet_process
3801 function. Otherwise the packets are never delivered, oops.
3803 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Disable force sending of packets when REKEY protocol is active.
3806 We must assure that no packet is sent directly when rekey is
3807 performed. All packets must be sent through packet queue.
3808 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3809 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3810 function is silc_[server/client]_packet_send_real to check
3813 * Replaced the SIM paths from example config files to
3814 /usr/local/modules. Also, make install creates now
3815 /usr/local/silc/logs directory to hold all the SILC server
3818 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3820 * Made the configure.in.pre work on Solaris. Patch by salo.
3822 * Made all ciphers compatible with non-x86 machines. Defined
3823 CBC mode macros into lib/silccrypt/ciphers_def.h.
3825 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3827 * Fixed the make install.
3829 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * When MAC computation fails the silc_packet_decrypt returned 0
3832 even though it was supposed to return -1. Fixed this. The
3833 affected file is lib/silccore/silcpacket.c.
3835 * Do not replace the config files in /etc/silc (in make install)
3836 if they already exist. Affected file ./Makefile.am.
3838 * Do not send re-key packets immediately but through packet queue.
3839 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3841 * Changed silc_net_check_host_by_sock to return FALSE if the
3842 IP/DNS could not be resolved. Though, it returns the IP address
3843 now even if it could not resolve it (but returns also FALSE).
3844 Affected file lib/silcutil/silcnet.[ch].
3846 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3848 * Added silc_pkcs_decode_identifier to decode the public key's
3849 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3850 Added also silc_pkcs_free_identifier. Added also new context
3851 SilcPublicKeyIdentifier.
3853 * Added -S option to the silc client. It is used to dump the
3854 contents of the specified public key file.
3856 * Changed the PKCS api to return the public key length when
3857 setting the public key.
3859 * Fixed a fatal bug in the public and private key file loading.
3860 Affected file lib/silccrypt/silcpkcs.c.
3862 * Execute the packet parsing for client with zero (0) timeout
3863 if the protocol is active. Affected file silcd/server.c.
3865 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Made the key generation options to the silcd program. Added
3868 -C option, equivalent to client's option.
3870 * Added new [ServerKeys] config section to the server. It
3871 configures the server's public and private key.
3873 * Defined generic Public Key Payload into the protocol
3874 specification to send specific type of public keys and
3877 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3878 public key or certificate.
3880 * Implemented the GETKEY command to the server and to the
3881 client library and on user interface.
3883 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Made preliminary `make install' work.
3887 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Added SilcServerRekey context into silcd/idlist.h.
3891 * Added the PFS support as defined in the specification to the
3892 SKE protocol. Affected files lib/silcske/*.c.
3894 * Added `ske_group' field to the SilcServerRekey context to hold
3895 the number of the SKE group that is used with PFS in re-key.
3896 Affected file silcd/idlist.h.
3898 * Added PFS re-key support to the server. Affected file is
3901 * Added silc_protocol_cancel to cancel execution of the next
3902 state of the protocol. Affected file is
3903 lib/silccore/silcprotocol.[ch].
3905 * Added the re-key support with and without PFS to the client
3906 library. Re-key is performed once in an hour, by default.
3908 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3909 Added silc_client_rekey_callback and silc_client_rekey_final.
3910 Affected files are lib/silcclient/protocol.[ch] and
3911 lib/silcclient/client.[ch].
3913 * Removed the `hmac_key' and `hmac_key_len' fields from the
3914 SilcClientConnection structure; not needed. Affected file is
3915 lib/silcclient/client.h.
3919 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Do not ask whether user wants to use the negotiated private key
3922 for private messages, just use it. Affected file is
3923 silc/local_command.c.
3925 * Added `send_enc_key' and `enc_key_len' fields to the
3926 SilcIDListData structure since they are needed in the re-key
3927 phase. Affected file is silcd/idlist.[ch].
3929 * Implemented the simple re-key protocol into the server.
3930 Affected files silcd/server.c and silcd/protocol.[ch]. The
3931 re-key will be performed once in an hour, by default.
3933 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3934 Added silc_server_rekey, silc_server_rekey_callback and
3935 silc_server_rekey_final.
3937 * Removed Tunneled flag from the protocol. Updated the code
3938 and the specifications.
3940 * Adde `pfs' field to the SilcIDListData to indicate whether
3941 the PFS is to be performed in the re-key. Affected file is
3944 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3947 int64 of at least the xintXX size. If void * is less that 4
3948 bytes uint32 * will be used. Defined bool as boolean.
3950 * Changed _ALL_ unsigned long and unsigned int to uint32,
3951 unsgined short to uint16 in the source tree.
3953 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3954 not handle clients that has entry->data.registered == FALSE.
3955 They are not in the network anymore. Affected file is
3958 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Implemented the sending of the SERVER_SIGNOFF notify in the
3961 server. Affected file is silcd/server.c.
3963 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3964 Added also silc_notify_payload_encode_args into the
3965 lib/silccore/silcnotify.[ch].
3967 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3968 Affected file silcd/packet_receive.c.
3970 * Implemented the SERVER_SIGNOFF notify handling in the client
3971 library. Affected file lib/silcclient/client_notify.c. Also,
3972 implemnted the printing of the SERVER_SIGNOFF info to the
3973 application. Affected file silc/client_ops.c.
3975 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3976 if the deleting was successful. Affected file silcd/idlist.[ch].
3978 * Added support for public key authentication in the connection
3979 authentication protocol in the client library. Affected file
3980 lib/silcclient/protocol.c.
3982 * Changed the server's silc_idlist_get_clients_by_* interface
3983 to support already allocated array so that new entries may be
3984 added to pre-allocated array. Affected file silcd/idlist.[ch].
3985 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3986 and command replies.
3988 * All command reply functions in the server now calls the
3989 pending command callback even if error occured. This way the
3990 error will be delivered to the client as well. Affected files
3991 silcd/command.c and silcd/command_reply.c.
3993 * Fixed INFO command to return local server's info if no server
3994 was provided. Affected file lib/silcclient/command.c.
3996 * Removed RESTART command for good. Updated the code and the
3999 * Rewrote parts of the task system. It is a bit simpler now.
4000 Removed unsued task priorities. The affected files are
4001 lib/silcutil/silctask.[ch].
4003 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Moved the USERS printing from the library to the application.
4006 Affected files lib/silcclient/command.c and silc/client_ops.c.
4008 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Added channel key re-key support. The re-key is perfomed
4013 only by the router and is done once in an hour. Added `rekey'
4014 field to the SilcChannelEntry in the server. Affected files
4015 silcd/server.c and silcd/idlist.h.
4017 * Added silc_task_unregister_by_context into the file
4018 lib/silcutil/silctask.[ch].
4020 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Added SILC_UMODE_GONE mode to indicate when the client is not
4023 present in the SILC network. Added also support to the local
4024 command AWAY that will set this mode. Added support of showing
4025 "xxx is gone" in WHOIS command. The USERS command shows the
4026 gone status as well.
4028 * Fixed setting server and router operator privileges in the
4029 server's UMODE command. Affected file silcd/command.c.
4031 * Merged the SKE KE1 and KE2 payloads into one payload. The
4032 new KE payload is equivalent to the old KE2 payload.
4034 Cleaned up the SKE Start Payload parsing. It now uses the
4035 simple buffer unformatting to do the parsing. A lot faster
4038 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4039 to the SKE that is used to indicate whether both of the SKE
4040 parties should perform authentication. By default only the
4041 responder performs authentication. By setting this flag also
4042 the initiator must do authentication. By default it is unset
4043 since in normal SKE case, client to server connection, only
4044 the responder should do authentication. When doing SKE between
4045 two clients both should perform authentication. Updated the
4046 code and the protocol specs.
4048 * A little fix to IDENTIFY command in the server. Search the
4049 client first by hash not nickname. Affected file is
4052 * Fixed the silc_client_close_connection to support closing
4053 the client to client connections wihtout deleting too much
4054 data. Affected file lib/silcclient/client.c.
4056 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4057 are received if protocol used to be active but is not anymore
4058 the application would crash due to NULL pointer dereference.
4059 Affected files silcd/server.c and lib/silcclient/client.c.
4061 * Added `hash' field to the SilcClientConnection to include
4062 the hash function negotiated in the SKE protocol.
4064 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4065 to set the channel founder authentication data. A client can
4066 claim the founder rights later by providing the authentication
4067 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4068 This way the channel founder can regain the channel founder
4069 privileges even it is left the channel. This works only on
4070 local server and the client must be connected to the same
4071 server to be able to regain the founder rights. Updated the
4072 protocol specs accordingly.
4074 Added support to the CMODE command in the client to set the
4075 founder auth data. Read the README to see how to set it.
4077 Added support to the CUMODE command to claim the founder
4078 rights. Read the README to see how to do it.
4080 Added support for the founder authentication to the Channel
4081 Entry in the server. Affected file silcd/idlist.h.
4083 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4084 server's CMODE command. Affected file silcd/command.c.
4086 * Added the following new functions into lib/silccore/silcauth.[ch]:
4087 silc_auth_get_method and silc_auth_get_data.
4089 * The server now saves the remote hosts public key to the
4090 SilcIDListData pointer. Affected file silcd/protocol.c.
4092 * The normal server now does not remove the channel entry from
4093 the cache if the founder authentication data is set. It used
4094 to remove it if the founder was the last one on the channel on
4095 the server and left the channel. The auth data is saved and
4096 if the channel is re-joined later the old entry is used with
4097 the old auth data. Affected files silcd/command_reply.c and
4100 * Removed the `pkcs' field from the SilcIDListData structure
4101 in the server; it is not used. Affected file silcd/idlist.h.
4103 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Fixed packet processing on slow links. Partial packets were
4106 never re-processed because the incoming data buffer was cleared
4107 by the application. Application must not directly clear the
4108 sock->inbuf, the packet processing routines handle it. Fixed
4109 this in client library and in server.
4111 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Fixed the WHOIS and IDENTIFY send reply function to really
4114 check whether to send list or just one entry. Affected file
4117 * Cleaned up the LEAVE command's channel key distribution. The
4118 affected file silcd/command.c.
4120 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4121 can enforce the channel mode as well. In that case the ID
4122 includes the ID of the server. The code now enforces the
4123 mode change if the router have different mode than the server.
4125 * The notify client operation with CMODE_CHANGE notify can now
4126 return NULL client_entry pointer if the CMODE was not changed
4127 by client. Application must check for this.
4129 * Added <Server ID> argument to INFO command to support server
4130 info fetching by Server ID.
4132 * Added silc_server_announce_get_channel_users to get assembled
4133 packets of channel users of the specified channel. Affected
4134 file silcd/server.[ch].
4136 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4137 was freed underneath the ID Cache.
4139 * Re-announce clients when the server received CHANNEL_CHANGE
4140 notify from the router. Affected file silcd/packet_send.c.
4142 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4145 crashed since it did not handle the fact that there is no cipher
4146 called "3" and didn't check the error condition. Now fixed.
4148 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4149 flag. It can be used to send message requests.
4151 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Implemented the RESTART command in the client.
4155 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4156 notice type messages. Added notice printing to the user
4159 * The channel keys are not re-generated if the channel's mode
4160 is PRIVKEY, ie private key on the channel exists. Affected
4161 files silcd/server.c and silcd/command.c.
4163 * Fixed a little bug in channel message delivery when channel
4164 private keys are set in the server. Affected file is
4165 silcd/packet_send.c.
4167 * Changed the setting on channel->on_channel = TRUE from the
4168 silc_client_save_channel_key to the JOIN command reply. The
4169 key payload is not received if the private channel key is set.
4170 Affected file lib/silcclient/command_reply.c and the
4171 lib/silcclient/client_channel.c.
4173 * When the CMODE_CHANGE notify is sent and the channel private
4174 key mode is removed the channel key must be re-generated in
4175 other cells as well. Added this support for the router in the
4176 silcd/packet_receive.c.
4178 * Added new local command NOTICE to send notice message on
4179 channel. Affected file silc/local_command.[ch].
4181 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4183 * Added new local command ME to the client. It is used to send
4184 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4185 some action. Affected file silc/local_command.[ch].
4187 * Changed channel_message and private_message client operations
4188 to deliver the message flags to the application. Added also
4189 the `flags' arguments to the silc_client_send_channel_message
4190 and silc_client_send_private_message functions. Affected file
4193 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Redefined the Private Message Payload to support private message
4196 keys and to support the new private message flags. Updated
4197 the protocol specs. Flags makes it possible to have for example
4198 CTCP style messages.
4200 * Added new type SilcPrivateMessagePayload and defined an API
4201 for it in the lib/silcclient/silcprivate.[ch].
4203 * Tested private message private keys successfully. Tested the
4204 private message key set, unset and list commands with the new
4207 * Redefined the Channel Message Payload to include the channel
4208 message flags (equal with private message flags) to support
4209 for example CTCP style messages.
4211 * Defined some of the message (for channel and private message)
4212 flags. Updated the protocol specs and added the flags to the
4213 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4215 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Added SilcKeyAgreementStatus type to the key agreement routines
4218 to indicate the current status and error if one occured.
4219 The status types are defined in the lib/silcclient/silcapi.h.
4221 * Added new local command KEY that is used to set and unset private
4222 keys for channels, set and unset private keys for private messages
4223 with remote clients and to send key agreement requests and
4224 negotiate the key agreement protocol with remote client. The
4225 key agreement is supported only to negotiate private message keys,
4226 it currently cannot be used to negotiate private keys for channels,
4227 as it is not convenient for that purpose.
4229 * Fixed a minor pending callback setting bug in the function
4230 silc_client_get_client_by_id_resolve, now the function works.
4231 Affected file lib/silcclient/idlist.c.
4233 * Added function silc_net_get_local_port to get local bound
4234 port by socket. Added to lib/silcutil/silcnet.[ch].
4236 * Added `sockets' and `sockets_count' fields to the SilcClient
4237 object. They hold the sockets of the listenning sockets in
4238 the client. Listenning sockets may be for example the key
4239 agreement server. Affected file lib/silcclient/client.[ch].
4240 Added functions the silc_client_add_socket and the
4241 silc_client_del_socket. They are exported to the application
4244 * Added ~./silc/clientkeys to support other client's public keys.
4246 * Renamed verify_server_key client operation to verify_public_key
4247 and added one argument to indicate the type of the connection
4248 (server, client etc.).
4250 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Added silc_server_connection_auth_request to handle the
4253 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4254 silcd/packet_receive.[ch].
4256 * Added silc_server_send_connection_auth_request into the
4257 silcd/packet_send.c to send the connection auth request packet.
4259 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4262 * Fixed the public key authentication in responder side in the
4263 server. The `auth_data' pointer includes the SilcPublicKey
4264 not the path to the public key. Affected file silcd/protocol.c.
4266 * Implemented the public key authentication in the initiator side
4267 in the server. Affected file silcd/protocol.c.
4269 * Removed the [RedirectClient] config section from the server
4270 configuration. Is not needed and I don't want to implement it.
4272 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Cleaned up the CMODE command in the server. It now works
4275 correctly and supports all the modes defined in the protocol.
4276 Affected file is silcd/command.c.
4278 * Added `hmac_name' field to the SilcChannelEntry in the server
4279 to hold the default HMAC of the channel. It can be set when
4280 creating the channel (with JOIN command). Affected files
4283 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4284 type to indicate the change of the current cipher and hmac
4285 on the channel. Client can safely ignore the <cipher> argument
4286 (if it chooses to do so) since the CHANNEL_KEY packet will
4287 force the channel key change anyway. The <hmac> argument is
4288 important since the client is responsible of setting the new
4289 HMAC and the hmac key into use.
4291 * Fixed the CMODE command in the client library as well.
4293 * Tested CMODE command in router environment successfully.
4295 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Show the version of the remote client (or server) when connecting
4298 to the server. It is logged to the log file. Affected file
4299 is silcd/protocol.c.
4301 * Fixed the KILLED notify handling in the client library. The
4302 client must be removed from all channels when receiving the
4305 Also, do not remove the client entry when giving the KILL
4306 command but when the KILLED notify is received.
4308 * Removed silc_idlist_find_client_by_nickname from the server.
4309 Not needed anymore. Affected files silcd/idlist.[ch].
4311 * Implemented the CHANNEL_CHANGE notify type handling to the
4312 server. Affected file silcd/server.c.
4316 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Added silc_server_send_notify_invite to send the INVITE
4319 notify between routers.
4321 * Implemented the INVITE command correctly to the server.
4323 * Implemented the INVITE notify type handling in the server.
4325 * Implemented the INVITE command to the client library and on the
4328 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Added function silc_server_get_client_resolve to find the
4331 client entry by ID from all ID lists and then resolve it
4332 (using WHOIS) if it cannot be found. Affected file is
4335 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Implemented the BAN command to the client library.
4339 * The JOIN command in the server now checks the invite list
4342 * Changed the silc_command_reply_payload_encode_va and the
4343 silc_command_payload_encode_va to support that if argument is
4344 NULL it ignores and checks the next argument. Affected file
4345 lib/silccore/silccommand.c.
4347 * Added silc_server_send_notify_ban to send the BAN notify
4348 type between routers.
4350 * Chaned the silc_notify_payload_encode to support that if
4351 argument is NULL it ignores and checks the next argument.
4352 Affected file lib/silccore/silcnotify.c.
4354 * Tested ban lists in router environment successfully.
4356 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Implemented BAN command to the server, in silcd/command.[ch].
4360 * Removed the BAN and INVITE_LIST modes from the CMODE command
4363 * Added function silc_string_match to regex match two strings.
4364 Affected files lib/silcutil/silcutil.[ch].
4366 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Redefined parts of the SilcChannelEntry in the server to support
4369 the new ban and invite lists.
4371 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Redefined the INVITE command. The same command can be used to
4374 invite individuals to the channel but also to manage the invite
4375 list of the channel (to add to and remove from the invite list).
4376 Updated the protocol specs.
4378 * Added new command SILC_COMMAND_BAN that can be used to manage
4379 the ban list of the channel. Updated the protocol specs.
4381 * Removed the channel modes: the SILC_CMODE_BAN and the
4382 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4383 in the CMODE command. The equivalent features are now available
4384 using INVITE and BAN commands. Updated the protocol specs.
4386 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4387 in the network about change in the current ban list. The notify
4388 type is not used by the client.
4390 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4391 support the invite lists.
4393 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Added new function silc_string_regexify that converts string
4396 including wildcard characters into regex string that can
4397 be used by the GNU regex library. Added into the file
4398 lib/silcutil/silcutil.[ch].
4400 Added silc_string_regex_combine to combine to regex strings
4401 into one so that they can be used as one regex string by
4402 the GNU regex library. Added into the file
4403 lib/silcutil/silcutil.[ch].
4405 Added silc_string_regex_match to match two strings. It returns
4406 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4408 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Imported GNU regex to the soruce tree into lib/contrib.
4411 Fixed some compiler warning from the regex.c.
4413 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Fixed MOTD command in the server to work in router environment.
4417 * Fixed the MOTD command in the client library to support
4418 the server argument in the command.
4420 * Added `nickname_len' argument to the silc_idlist_add_client
4421 in the server, as the `nickname' argument may be binary data
4424 * Added silc_idlist_get_channels to return all channels from
4427 * Implemented LIST command to the server. Affected file is
4430 * Implemented the LIST command to the client library and on the
4433 * Added [<user count>] argument to the LIST command reply.
4434 With private channels the user count is not shown.
4436 * Updated TODO and README.
4438 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * The client entry's data.registered must be TRUE even with
4441 global client entry on global client list. The data.registered
4442 is used to check whether the client is anymore in the network,
4443 for example with WHOWAS command so it must be valid.
4445 * Fixed the WHOWAS command in the server. It now actually works
4446 in router environment. Added function into silcd/command_reply.c
4447 silc_server_command_reply_whowas_save.
4449 * Added silc_idlist_purge function to the silcd/idlist.c
4450 to periodically purge the ID Cache.
4452 * Fixed INFO command in the server. It works now in router
4453 environment. Added <server name> argument to the INFO command
4454 reply. Updated the protocol specs.
4456 * Fixed minor bug in silc_idcache_purge to not purge if the
4457 expire value is zero.
4459 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4460 they were buggy because of the WHOWAS information.
4462 * Fixed local command MSG to handle the async resolving of
4463 the remote client properly. It used to fail the first MSG.
4464 Affected file silc/local_command.c.
4466 * Added `data_len' field to SilcIDCache context.
4468 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Update TODO. Todo in commands in the server.
4472 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4475 used by routers as broadcast packet to inform other routers
4476 about the changed user mode.
4478 Implemented the notify handling in the server. Affected file is
4479 silcd/packet_receive.c. Added the function
4480 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4482 * Added new generic Channel Payload and deprecated the New Channel
4483 Payload. The New Channel Payload is now the generic Channel
4486 * Added new argument `mode' to the silc_server_send_new_channel
4487 as it is required in the Channel Payload now.
4489 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4490 and created a new and real SilChannelPayload to represent the
4491 new generic Channel Payload. Implemented the encode/decode
4492 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4494 * Added silc_server_get_client_channel_list to return the list
4495 of channels the client has joined for WHOIS command reply.
4496 Affected file silcd/server.[ch].
4498 * Implemented the channel list sending in the WHOIS command reply
4499 in server and in the client.
4501 Implemented the channel list displaying on the user interface
4502 as well. Affected file silc/client_ops.c.
4504 * Added silc_channel_payload_parse_list to parse list of Channel
4505 Payloads. It returns SilcDList list of SilcChannelPayloads.
4506 Client for example can use this function to parse the list of
4507 channels it receives in the WHOIS command reply. The caller
4508 must free the list by calling silc_channel_payload_list_free.
4509 Affected files lib/silccore/silcchannel.[ch].
4511 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Added one new argument <user mode> to the WHOIS command reply
4514 to return the mode of the user in SILC. Updated the protocol
4517 Implemented it to the server and client.
4519 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Fixed the mode printing on the user interface on joining.
4522 Affected file silc/client_ops.c.
4524 * Implemented the UMODE command and user modes in general to the
4525 client library and to the user interface.
4527 * Implemented the UMODE command to the server.
4529 * The server now sends UNKNOWN_COMMAND error status if client sends
4530 unknown command. Affected file silcd/command.c.
4532 * All server commands now handle the command identifier the right
4533 way when sending the command reply to the client. The client can
4534 use to identify the command replies with the identifier.
4536 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Added silc_server_get_client_route to resolve the route to
4539 the client indicated by the client ID. Affected file is
4542 * Added silc_server_relay_packet as general function to relay
4543 packet to arbitrary destination. This deprecates functions
4544 like _send_private_message_key, _relay_notify etc. Affected
4545 file is silcd/packet_send.[ch].
4547 Removed silc_server_send_key_agreement,
4548 silc_server_send_private_message_key and
4549 silc_server_packet_relay_notify functions from the file
4550 silcd/packet_send.[ch].
4554 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4555 server. Affected file silcd/packet_receive.[ch].
4557 * Implemented the KILL command to the client. Implemented the
4558 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4559 Affected files lib/silcclient/command[_reply].c and
4560 lib/silcclient/client_notify.c. Implemented the KILL notify
4561 printing in the user inteface.
4563 * Fixed a lot silc_parse_nick memory leaks from the client
4564 library in the file lib/silcclient/command.c.
4566 * Changed the silc_server_send_notify_on_channels's `sender'
4567 argument from SilcSocketConnection to SilcClientEntry to
4568 check the sender as entry and not as connection object and not
4569 to send to the client provided as argument. The affected file
4570 is silcd/packet_send.[ch].
4572 * The notify packets that are destined directly to the client used
4573 to not to be processed by the server. Now changed that and the
4574 server processes all notify packets. After relaying the packet
4575 to the client the notify packet is processed in the server.
4577 * The silc_server_free_client_data now checks whether there is
4578 pending outgoing traffic for the client and purges the data to
4579 the network before removing the client entry.
4581 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4584 an client is killed from the SILC Network. Updated the protocol
4587 Added new function silc_server_send_notify_killed to the
4588 silcd/packet_send.[ch].
4590 * Added function silc_server_packet_relay_notify to relay notify
4591 packets that are destined directly to a client. In this case
4592 the server does not process the notify packets but merely relays
4593 it to the client. Affected file silcd/packet_send.[ch].
4595 Added also silc_server_packet_process_relay_notify to check
4596 whereto relay the notify. Affected file is
4597 silcd/packet_receive.[ch].
4599 * Implemented the KILL command to the server.
4603 * Added the backup schema desgined last fall to the protocol
4604 specs for everyone to see. The specification is in the
4605 *-spec-xx.txt draft and the packet type definitions for the
4606 backup routers is in *-pp-xx.txt draft. Thusly, added also
4607 new packet type SILC_PACKET_CELL_ROUTERS.
4609 * A big security problem in the implementation discovered. The
4610 signoff of an client did not cause new channel key generation
4611 which it of course should've done. The channel keys must be
4612 always re-generated when client leaves (or signoffs) the channel.
4613 The silc_server_remove_from_channels funtion now handles
4614 the channel key re-generation.
4616 * Added `sender' argument to the silc_server_send_notify_on_channels
4617 to not to send the client provided as argument. Affected file
4618 silcd/packet_send.[ch].
4620 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Implemented OPER and SILCOPER commands into the server and
4625 * Added silc_auth_verify and silc_auth_verify_data to verify
4626 the authentication directly from the authentication payload.
4627 It supports verifying both passphrase and public key based
4628 authentication. Affected file lib/silccore/silcauth.[ch].
4630 * Added `hash' field to the SilcIDListData structure. It is the
4631 hash negotiated in the SKE protocol. Affected file is
4634 * Slight redesigning of the SilcAuthPayload handling routines.
4635 Do not send SilcPKCS but SilcPublicKey as argument.
4637 * Implemented the public key authentication support to the
4638 serverconfig. The public key is loaded from the provided path
4639 and saved as authentication data to void * pointer. Thus,
4640 changed the unsigned char *auth_data to void *auth_data;
4642 * Fixed SHUTDOWN command to send the reply before the server
4643 is shutdown. :) Affected file silcd/command.c.
4645 * Fixed fatal bug in CONNECT command. The hostname was invalid
4646 memory and server crashed. Affected file silcd/command.c.
4648 * Fixed fatal bug in CLOSE command. The server_entry became
4649 invalid but was referenced later in the command. Affected file
4652 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Fixed fatal bug in failure packet handling. Server ignored
4655 the failure and thus crashed when it came.
4659 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4662 that the command may be executed only once in (about) 2 seconds.
4663 The old SILC_CF_LAG flag is same but allows command bursts up
4664 to five before limiting.
4666 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4667 server code. Various commands now includes the CF_LAG_STRICT
4668 flag to disallow any kind of miss-use of the command.
4670 * Fixed the silc_buffer_unformat to not to allocate any data
4671 if the length of the data is zero. It used to allocate the
4672 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4674 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Changed the format of AdminConnection configuration section
4677 in the server. Added username of the admin to the format.
4678 Affected files silcd/serverconfig.[ch].
4680 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4681 to return admin configuration data by host, username and/or
4684 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Implemented WHOWAS command to the server. Added the functions:
4688 silc_server_command_whowas_parse,
4689 silc_server_command_whowas_send_reply,
4690 silc_server_command_whowas_from_client and
4691 silc_server_command_whowas_from_server
4693 * Added <Client ID> argument to the WHOWAS command reply. Updated
4694 the protocol specs accordingly.
4696 * Implemented WHOWAS command and command_reply to the client
4699 Implemented the WHOWAS printing on the user interface.
4701 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added new argument to the WHOWAS command reply, the real name.
4704 It is an optional argument. Updated the protocol specs.
4706 * Added SilcIDCacheDestructor callback that is registered when
4707 the SilcIDCache is allocated. The callback is called when
4708 an cache entry in the ID Cache expires, or is purged from the
4709 cache. Added into lib/silccore/idcache.[ch].
4711 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4712 to destruct the client entries when the cache entry expires.
4713 Other ID Cache's in server and in the client library ignores
4716 * If the ID Cache entry's `expire' field is zero then the entry
4717 never expires. Added boolean `expire' argument to the
4718 silc_idcache_add function in the lib/silccore/idcache.[ch].
4719 If it is TRUE the default expiry value is used.
4721 * Added silc_server_free_client_data_timeout that is registered
4722 when client disconnects. By default for 5 minutes we preserve
4723 the client entry for history - for WHOWAS command.
4725 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Added support to the server to enforce that commands are not
4728 executed more than once in 2 seconds. If server receives
4729 commands from client more frequently, timeout is registered
4730 to process the commands. Affected file silcd/command.c.
4731 Added new function silc_server_command_process_timeout.
4733 * Changed NICK_NOTIFY handling in client library to check that
4734 if the client's nickname was changed, so there is no need to
4735 resolve anything from the server.
4737 * Removed error printing from the WHOIS and IDENTIFY commands.
4738 If error occurs then it is ignored silently in the client library.
4739 The application, however, may map the received error to
4740 human readable error string. The application currently maps
4741 the NO_SUCH_NICKNAME error to string.
4743 * Made the command status message public to the application. Moved
4744 them from lib/silcclient/command_reply.c to
4745 lib/silcclient/command_reply.h. The application can map the
4746 received command status to the string with the
4747 silc_client_command_status_message function.
4749 * Added check to the server to check that client's ID is same
4750 as the Source ID in the packet the client sent. They must
4753 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added dist-bzip hook to the Makefile.am to make bzip2
4756 compressed distributions.
4758 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4760 * Server now enforces the maximum length for the nickname and
4761 the channel as protocol specification dictates. 128 bytes for
4762 nickname and 256 bytes for channel name.
4764 * Moved the WHOIS printing to the application. The client libary
4765 does not print out the WHOIS information anymore, the application
4766 must do it. Renamed silc_client_command_reply_whois_print to
4767 the silc_client_command_reply_whois_save.
4769 The client's idle time is also sent to the application now, and
4770 the idle is shown on screen.
4772 * Added silc_client_command_reply_identify_save to save the
4773 received IDENTIFY entries.
4775 * Do not check for channel private keys in message sending and
4776 reception if the channel does not have the PRIVKEY mode set.
4777 Affected file lib/silclient/client_channel.c.
4779 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4782 just surfaced after chaning the JOIN procedure.
4784 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Added silc_client_get_clients_by_list to get client entries
4787 from Client ID list, that is returned for example by JOIN
4788 and USERS command replies. The application should use this
4789 function for example when JOIN command reply is received to
4790 resolve the clients already on the channel (library does not
4791 do that anymore as USERS command reply is not used in the JOIN
4792 procedure anymore). Affected files lib/silcclient/silcapi.h and
4793 lib/silcclient/idlist.c.
4795 * JOIN command reply and USERS command reply returns now SilcBuffer
4796 pointers instead of unsigned char pointers when returning
4797 the client list and mode list.
4799 * Added <Client ID> argument to the JOIN command reply, mainly
4800 for the server to identify for which client the command was
4801 originally sent. Updated protocol specs accordingly.
4803 * Added SilcDlist private_key pointer to the SilcChannelEntry
4804 in the client to support the channel private keys. Affected
4805 file is lib/silcclient/idlist.h.
4807 * Added SilcChannelPrivateKey argument to the function
4808 silc_client_send_channel_message so that application can choose
4809 to use specific private ke if it wants to. If it is not provided,
4810 the normal channel key is used, unless private keys are set.
4811 In this case the first (key that was added first) is used
4812 as the encryption key.
4814 * Implemented the support for channel private key handling.
4815 Implemented the following functions:
4817 silc_client_add_channel_private_key,
4818 silc_client_del_channel_private_keys,
4819 silc_client_del_channel_private_key,
4820 silc_client_list_channel_private_keys and
4821 silc_client_free_channel_private_keys
4823 Affected file lib/silcclient/client_channel.c.
4825 * Added the support for the private keys in the channel message
4826 sending and encryption and in the message reception and
4827 decryption. Affected funtions are
4828 silc_client_send_channel_message and silc_client_channel_message.
4830 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4832 * Added SKE's key verify callback to the client library's
4833 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4835 * Removed the statement that server (or router) must send USERS
4836 command reply when joining to the channel so that the client
4837 knows who are on the channel. Instead, the client list and
4838 client's mode list is now sent in the JOIN command reply to the
4839 client who joined channel. This is better solution.
4841 * Added function silc_server_get_users_on_channel and function
4842 silc_server_save_users_on_channel to the silcd/server.[ch].
4844 * Removed function silc_server_command_send_users from the
4847 * Do not show topic on the client library anymore. The topic is
4848 sent in the command reply notify to the application and the
4849 application must show the topic now.
4851 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Added client searching by nickname hash into the IDENTIFY and
4854 WHOIS commands in the server as they were clearly missing from
4855 them. Affected file is silcd/command.c.
4857 * Fixed a bug in private message receiving in the client library.
4858 The remote ID was freed and it wasn't supposed, now it is
4861 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Minor fix to the channel payload; allocate the data area, as it
4864 needs to be of specific length.
4866 * If the key agreement port is zero then the operating
4867 system will define the bound port. Affected files are
4868 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4870 * Added new function silc_channel_payload_decrypt into the file
4871 lib/silccore/silcchannel.[ch].
4873 * Moved the channel message etc, check from silc_packet_decrypt
4874 to applications. The library calls now a generic
4875 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4876 when the packet is either normal or special. This was done to
4877 allow more wide range of checking that was not allowed when
4878 the code was in library. Now applications can do virtually any
4879 checks to the packet and return to the library the decision how
4880 the packet should be processed. Affected files are
4881 lib/silccore/silcpacket.[ch].
4883 Added silc_server_packet_decrypt_check to the server and
4884 silc_client_packet_decrypt_check to the client library.
4886 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4887 to send with specified source and destination information.
4889 * Channel message delivery between routers was broken after the
4890 channel key distribution was fixed earlier. The channel key
4891 was used be to distributed to other routers as well which is not
4892 allowed by the protocol. Now this is fixed and channel keys
4893 really are cell specific and the channel message delivery between
4894 routers comply with the protocol specification.
4896 * Fixed various commands in server to check also the global list
4897 for the channel entry and not just the local list. The affected
4898 file silcd/command.c.
4900 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Added assert()s to buffer formatting and unformatting routines
4903 to assert (if --enable-debug) when error occurs. Affected
4904 file: lib/silcutil/silcbuffmt.c.
4906 * Changed to auto-reconnect to check whether the remote host is
4907 router and register the re-connect timeout if it is. It used
4908 to check that whether we are normal server, but router must do
4909 auto-reconnect with another router as well. Affected file
4912 * Removed the [<key len>] option from CMODE command as the cipher
4913 name decides the key length, nowadays. See the defined ciphers
4914 from the protocol specification.
4916 * Added [<hmac>] option to the CMODE command to define the HMAC
4917 for the channel. Added SILC_CMODE_HMAC channel mode.
4919 * Added [<hmac>] option for the JOIN command so that user can
4920 select which HMAC is used to compute the MACs of the channel
4923 * Added Hmac field to the Channel Message Payload. The integrity
4924 of plaintext channel messages are now protected by computing
4925 MAC of the message and attaching the MAC to the payload. The
4926 MAC is encrypted. Now, it is clear that this causes some
4927 overhead to the size of the packet but rationale for this is that
4928 now the receiver can verify whether the channel message decrypted
4929 correctly and also when private keys are set for the channel the
4930 receiver can decrypt the packet with several keys and check from
4931 the MAC which key decrypted the message correctly.
4933 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4934 lib/silccrypt/silccipher.[ch].
4936 * Added silc_hash_len to return the digest length into the
4937 lib/silcrypt/silchash.[ch].
4939 * Rewrote parts of Silc Channel Payload interface in the
4940 lib/silccore/silcchannel.[ch]. The encode function now also
4941 encrypts the packet and parse function decrypts it.
4943 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Fixed a minor formatting bug in the SKE's key material processing.
4946 It actually might have processed the keys wrong way resulting
4949 * Redefined the mandatory HMAC algorithms and added new algorithms.
4950 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4951 and hmac-md5 truncated to 96 bits. The mandatory is now
4952 hmac-sha1-96. Rest are optional (including the one that used
4953 to be mandatory). Rationale for this is that the truncated HMAC
4954 length is sufficient from security point of view and can actually
4955 make the attack against the HMAC harder. Also, the truncated
4956 HMAC causes less overhead to the packets. See the RFC2104 for
4959 * Added new [hmac] configuration section. The SKE used to use
4960 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4961 is of course wrong. The official names that must be proposed in
4962 the SKE are the ones defined in the protocol specification
4963 (hmac-sha1-96 for example). The user can configure any hmac
4964 using any hash function configured in the [hash] section. At
4965 least, the mandatory must be configured.
4967 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4969 * Added HMAC list to the SKE proposal list. It has now both
4970 hash algorithm list and HMAC list. This makes the protocol
4971 incompatible with previous versions. The SKE now seems to work
4972 the way it is supposed to work, for the first time actually.
4974 * Defined plain Hash algorithms to the protocol specification.
4977 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Implemented support for key agreement packets into the server.
4980 Added functions silc_server_key_agreement and
4981 silc_server_send_key_agreement. Other than these functions,
4982 server has nothing to do with this packet.
4984 * Added support for private message key packets into the server.
4985 Added functions silc_server_private_message_key and
4986 silc_server_send_private_message_key.
4990 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4991 called in the protocol's final callback instead in the END
4992 protocol state. This makes a little more sense and in the same
4993 time in client we can use the same protocol routines for normal
4994 key exchange and to key agreement packet handling as well.
4996 * Added to both client's and server's KE protocol context the
4997 SilcSKEKeyMaterial pointer to save the key material. We will
4998 bring the key material to the protocol's final callback by doing
4999 this. The final callback must free the key material.
5001 * Added SKE's packet_send callback into client's KE protocol
5002 context so that the caller can choose what packet sending function
5003 is used. This way we can use different packet sending when
5004 doing normal SKE when doing key agreement packet handling (in
5005 the key agreement packet handling we do not want to encrypt
5008 * Implemented the responder side of the key agreement routines
5009 in the client. The client can now bind to specified port and
5010 accept incoming key negotiation. The key material is passed
5011 to the application after the protocol is over.
5013 * Implemented the processing of incoming Key Agreement packet
5014 in the client. Added function silc_client_key_agreement to
5017 * Implemented the intiator side of the key agreement routines
5018 in the client. The client can now initiate key agreement with
5019 another remote client. The key material is passed to the
5020 application after the protocol is over.
5022 * Created client_keyagr.c to include all the key agreement
5025 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5026 SILC_TASK_CALLBACK except that it is not static.
5028 * Created client_notify.c and moved the Notify packet handling
5029 from the client.[ch] into that file.
5031 * Created client_prvmsg.c and moved all private message and
5032 private message key routines from the client.[ch] into that file.
5034 * Create client_channel.c and moved all channel message and
5035 channel private key routines from the client.[ch] into that file.
5037 * Changed silc_client_get_client_by_id_resolve to resolve with
5038 WHOIS command instead of IDENTIFY command, in the file
5039 lib/silclient/idlist.c.
5041 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Implemented the SKE's responder side to the Client library.
5045 * When FAILURE is received to the protocol do not trust it
5046 blindly. Register a timeout to wait whether the remote closes
5047 the connection as it should do it, only after that process the
5048 actual failure. This was changed to both client and server.
5050 * Added client_internal.h to include some of the structures
5051 there instead of client.h in lib/silcclient/.
5053 * Added function silc_task_unregister_by_callback to unregister
5054 timeouts by the callback function.
5056 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Some "Incomplete WHOIS info" errors has been appearing on the
5059 log files. Took away the entry->userinfo check from WHOIS
5060 reply sending. The entry->userinfo is now " " if client did not
5061 provide one. I thought this was fixed earlier but something
5062 is wrong still. Let's see if the error still appears.
5064 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Fixed a minor bug in the login when the channel key is
5067 re-generated in the server. It used to generate the key in
5068 wrong order and thus caused problems in the channel traffic.
5070 * Fixed a minor bug in channel key distsribution after
5071 KICK command. The key was not sent to the router even though
5074 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Added silc_ske_process_key_material_data as generic routine
5077 to process any key material as the SILC protocol dictates. The
5078 function is used by the actual SKE library but can be used by
5079 applications as well. This relates to the private message keys
5080 and the channel private keys since they must be processed the
5081 same way the normal SILC session keys. The protocol dictates
5082 this. Affected files: lib/silcske/silcske.[ch].
5084 Added also silc_ske_free_key_material to free the
5085 SilcSKEKeyMaterial structure.
5087 * Defined silc_cipher_set_key function to set the key for
5088 cipher without using the object's method function. The affected
5089 files: lib/silccrypt/silccipher.[ch].
5091 * Implemented silc silc_client_add_private_message_key,
5092 silc_client_add_private_message_key_ske,
5093 silc_client_del_private_message_key,
5094 silc_client_list_private_message_keys and
5095 silc_client_free_private_message_keys functions in the
5098 Added functions silc_client_send_private_message_key to send
5099 the Private Message Key payload and silc_client_private_message_key
5100 to handle incoming Private Message Key payload.
5102 * Added Cipher field to the Private Message Key payload to set
5103 the cipher to be used. If ignored, the default cipher defined
5104 in the SILC protocol (aes-256-cbc) is used.
5106 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Removed lib/silcclient/ops.h file.
5110 Redefined parts of the SILC Client Library API. Created new
5111 file silcapi.h that deprecates the ops.h file and defines the
5112 published Client Library API. Defined also private message key
5113 API and channel private key API into the file.
5115 This is the file that the application must include from the
5116 SILC Client Library. Other files need not be included by
5117 the application anymore.
5119 * Added new key_agreement client operation callback and also
5120 defined the Key Agreement library API for the application.
5122 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5125 is used by clients to request key negotiation between another
5126 client in the SILC network. If the negotiation is started it
5127 is performed using the SKE protocol. The result of the
5128 negotiation, the secret key material, can be used for example
5129 as private message key.
5131 Implemented the Key Agreement payload into the files
5132 lib/silccore/silauth.[ch].
5134 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5136 * Redefined ciphers for the SILC protocol. Added some new ciphers
5137 and defined the key lengths for the algorithms. Changed the
5138 code accordingly. The default key length is now 256 bits.
5140 * Fixed SKE key distribution function silc_ske_process_key_material
5141 when the key length is more than 128 bits. The default key
5142 length in SILC is now 256 bits.
5144 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5145 to indicate unsupported algorithm.
5147 * Renamed rijndael.c to aes.c and all functions as well.
5149 * Fixed a long standing channel key setting bug in client library.
5150 Weird that it has never surfaced before.
5152 * Fixed bug in channel deletion. If the entire channel is removed
5153 then it must also delete the references of the channel entry
5154 from the client's channel list as the client's channel entry and
5155 the channel's client entry share same memory.
5157 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Implemented CONNECT and SHUTDOWN commands in the client.
5161 * Implemented CLOSE command to the client.
5163 * Added the function silc_idlist_find_server_by_name into the
5164 files silcd/idlist.[ch].
5166 Added the function silc_idlist_find_server_by_conn into the
5167 files silcd/idlist.[ch].
5169 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * DIE command was renamed to SHUTDOWN. Updated the both code
5174 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5175 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5177 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5180 * Added function silc_server_create_connection function to create
5181 connection to remote router. My server implementation actually
5182 does not allow router to connect to normal server (it expects
5183 that normal server always initiates the connection to the router)
5184 so the CONNECT command is only good for connecting to another
5187 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5190 or some other client was kicked from the channel.
5192 Implemented the handling of the notify type to both client
5195 Implemented silc_server_send_notify_kicked to send the KICKED
5196 notify. It is used to send it to the server's primary router.
5198 * Implemented the KICK command into server and client.
5200 * Added `query' argument to the silc_idlist_get_client function
5201 to indicate whether to query the client from server or not if
5204 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5205 to indicate that the client is not channel founder.
5209 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Removed the rng context from SilcPacketContext structure and
5212 changed that the packet routine uses the Global RNG API.
5214 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Added support for quit message that client can "leave" on the
5217 channel when it quits the SILC. It is ditributed inside the
5218 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5220 Added silc_server_free_client_data that will take the
5221 signoff message as argument.
5223 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5225 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Updated parts of the protocol specification to keep it up
5230 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5233 payloads in one packet.
5235 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5236 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5237 use now the new List flag.
5239 * Also deprecated the following packet types: REPLACE_ID,
5240 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5242 * Added list support for Notify packet in server.
5244 * Added silc_server_send_notify_channel_change to send the
5245 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5246 the silc_server_send_replace_id.
5248 * Added silc_server_send_notify_nick_change to send the
5249 NICK_CHANGE notify type. Deprecates the function
5250 silc_server_send_replace_id.
5252 * Added silc_server_send_notify_join to send the JOIN notify type.
5253 Deprecates the function silc_server_send_new_channel_user.
5255 * Added silc_server_send_notify_leave to send LEAVE notify type.
5256 Deprecates the function silc_server_send_remove_channel_user.
5258 * Added silc_server_send_notify_cmode and
5259 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5260 types. Deprecates the silc_server_send_set_mode function.
5262 * Added SERVER_SIGNOFF notify type to indicate that server has
5263 quit. This means that all clients on the channel from that
5264 server will drop. This can be also used when netsplit happens.
5266 Deprecated REMOVE_ID packet type since it is not needed anymore
5269 Added silc_server_send_notify_server_signoff to send the
5270 SERVER_SIGNOFF notify type. Deprecates the function
5271 silc_server_send_remove_id.
5273 Added also silc_server_send_notify_signoff to send the
5274 SIGNOFF notify type.
5276 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5277 SILC protocol from this day on. Changed the protocol
5278 specification as well.
5280 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5281 notify type. It is used between routers to notify about
5282 topic changes on a channel.
5284 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5287 * Partly updated the protocol specification to comply with the
5288 changes now made. It is still though a bit outdated.
5290 * The JOIN notify type now takes one extra argument <Channel ID>.
5291 The packet used to be destined to the channel but now the
5292 JOIN type may be sent as list thus it is impossible to
5293 destine it to any specific channel. By adding this argument
5294 it is again possible.
5296 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Added CREDITS file. The CHANGES and CREDITS file will appear
5299 in the distribution as well.
5301 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5304 types in the server's silcd/packet_receive.c.
5306 * Implemented CMODE and CUMODE to work in router environment.
5308 * Fixed minor encoding and decoding buglet from the
5309 lib/silccore/silcmode.c.
5311 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5314 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5316 * Changed all SilcConfigServer* and silc_config_server* to
5317 SilcServerConfig* and silc_server_config*, respectively.
5320 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Associated the ID (client or server ID) to the Authentication
5323 Payload to avoid any possibility of forging. Updated the
5324 protocol specification and the code accordingly.
5326 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * The RSA key length is now save to the RsaKey context in the
5329 key generation process in lib/silccrypt/rsa.c. The key length
5330 is now used to figure out the maximum size of the block allowed
5331 to be encrypted/signed.
5333 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5334 is equivalent to the silc_mp_mp2bin but does not allocate any
5337 * Changed silc_mp_mp2bin API to take length argument. If it is
5338 non-zero then the buffer is allocated that large. If zero, then
5339 the size is approximated using silc_mp_sizeinbase, which however
5342 * Created Global RNG API which is global RNG that application can
5343 initialize. After initializing, any routine anywhere in the
5344 code (including library) can use RNG without allocating a new
5345 RNG object. This was done to allow this sort of use of the
5346 RNG in code that has no chance to allocate RNG object. All
5347 applications currently allocate this and many routines in the
5348 library use this. Affected file lib/silccrypt/silcrng.[ch].
5350 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5351 it to use the Global RNG API.
5353 * Defined Authentication Payload into protocol specification that
5354 is used during SILC session to authenticate entities. It is
5355 used for example by client to authenticate itself to the server
5356 to obtain server operator privileges.
5358 Implemented this payload into the lib/silccore/silcauth.[ch].
5359 Implemented also routines for public key based authentication
5360 as the new protocol specification dictates.
5362 Moved definitions of different authentication methods from
5363 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5365 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5366 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5367 silc_pkcs_verify_with_hash functions into the file
5368 lib/silccrypt/silcpkcs.[ch].
5370 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5372 * The client entry's userinfo pointer must be always valid.
5373 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5374 will fail since it requires the userinfo. Now, the userinfo
5375 is allocated as "" if actual userinfo does not exist. Actually,
5376 it must exist and it is totally Ok to drop client connections
5377 that does not announce the userinfo. However, we will make
5378 this workaround for now.
5380 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5381 to return the remote port by socket.
5383 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5386 SILC_SERVER_PENDING_EXEC and added an new macro
5387 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5388 data or when error occurs while processing the pending command.
5390 Added new argument `destructor' into silc_server_command_pending
5391 and to the SilcServerCommandPending object. This destructor is
5392 now called after calling the pending callback or if error occurs
5393 immediately. If error occurs the actual pending callback won't
5394 be called at all - only the destructor. The destructor may be
5395 NULL if destructor is not needed.
5397 All this applies for client library code as well. Similar
5398 changes were made there as well for the pending commands.
5400 In the client, the application must now allocate the
5401 SilcClientCommandContext with the silc_client_command_alloc
5404 * Added reference counter to the SilcServerCommandContext. Added
5405 function silc_server_command_alloc and silc_server_command_dup
5408 Same type of functions added to the client library for the same
5411 * Removed the cmd_ident from IDListData away since it is now
5412 global for all connections. It is the command identifier used
5413 in command sending and with pending commands. The affected file
5416 * Added reference counter to the SilcSocketConnection objecet to
5417 indicate the usage count of the object. The object won't be
5418 freed untill the reference counter hits zero. Currently only
5419 server uses this, and client ignores it. The client must be
5420 set to use this too later. The affected files are
5421 lib/silccore/silcsockconn.[ch]. Added also the function
5422 silc_socket_dup to increase the reference counter.
5424 This was mainly added because it is possible that the socket
5425 is removed underneath of pending command or other async
5426 operation. Now it won't be free'd and proper DISCONNECTING
5427 flags, etc. can be set to avoid sending data to connection that
5428 is not valid anymore.
5430 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5431 the connection. After that it sets SILC_SET_DISCONNECTED.
5432 It is, however, possible that the socket data is not still freed.
5433 The silc_server_packet_process now checks that data is not
5434 read or written to connection that is DISCONNECTED. The socket
5435 get's freed when the reference counter hits zero.
5437 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Changed the client operation API: channel_message operation's
5440 `sender' is now the client entry of the sender, not the nickname
5441 and the `channel' is the channel entry, not the channel name.
5443 In the private_message operation the `sender' is now also the
5444 client entry of the sender not the nickname.
5446 Affected file is lib/silcclient/ops.h and all applications
5447 using the client operations.
5449 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Moved the calling of ops->connect() from connect_to_server_final
5452 into receive_new_id functin since that is the point when the
5453 client is actually allowed to send traffic to network. The
5454 affected file is lib/silcclient/client.c.
5456 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5459 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5460 (if needs broadcasting) instead of broadcasting the packets one
5461 by one which would make a burst in the network traffic.
5463 * Added `broadcast' argument to the functions in silcd/server.[ch]
5464 silc_server_create_new_channel[_with_id] to indicate whether
5465 to send New Channel packet to primary router.
5467 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Added new function into the silcd/server.[ch] files:
5470 silc_server_create_new_channel_with_id to create new channel with
5471 already existing Channel ID.
5473 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5474 lib/silccore/silcpacket.h. This packet is used t send list of
5475 Set Mode payloads inside one packet. Server uses this to set
5476 the modes for the channels and clients on those channels, that it
5477 announced to the router when it connected to it. The protocol
5478 specification has been updated accordingly.
5480 * The silc_server_new_channel did not handle the packet coming
5481 from normal server as it normally does not send that. However,
5482 when it announces its channels it does send it. Implemented
5483 the support for that.
5485 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5486 into the file lib/silccore/id.h.
5488 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Fixed memory leaks in the functions silc_idlist_del_client,
5491 silc_idlist_del_channel and silc_idlist_del_server in the file
5492 silcd/idlist.c. All of those leaked like a sieve.
5494 * Fixed some small memory leaks in the client's function
5495 silc_client_notify_by_server.
5497 * Added functions into silcd/server.c: silc_server_announce_clients,
5498 silc_server_announce_channels and silc_server_announce_server.
5499 These functions are used by normal and router server to announce
5500 to its primary router about clients, channels and servers (when
5501 router) that we own. This is done after we've connected to the
5504 These functions effectively implements the following packet types:
5505 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5506 and SILC_PACKET_NEW_ID_LIST.
5508 * Added new functions into the silcd/packet_receive.[ch]:
5509 silc_server_new_id_list, silc_server_new_channel_list and
5510 silc_server_new_channel_user_list to handle the incoming
5511 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5513 * Added support of changing Channel ID in the function
5514 silc_server_replace_id. If the server that announces a channel
5515 to the router already exists in the router (with same name but
5516 with different Channel ID), router is responsible to send
5517 Replace ID packet to the server and force the server to change
5518 the Channel ID to the one router has.
5520 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5521 client that the Channel ID has been changed by the router. The
5522 normal server sends this to the client. Client must start using
5523 the new Channel ID as the channel's ID.
5525 Implemented handling of this new type into lib/silcclient/client.c
5526 into the function silc_client_notify_by_server.
5528 * Added new function silc_idlist_replace_channel_id into the files
5529 silcd/idlist.[ch] to replace the Channel ID.
5531 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Call silc_server_command_identify_check always when processing
5534 the IDENTIFY command in silcd/command.c
5536 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5539 send keepalive packets. The packet can be sent by clients,
5540 servers and routers.
5542 Added function silc_socket_set_heartbeat into the file
5543 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5544 If not set, the heartbeat is not performed. The actual
5545 heartbeat is implemented in the low level socket connection
5546 library. However, application is responsible of actually
5549 Added silc_server_send_heartbeat to send the actual heartbeat
5550 packet into silcd/packet_send.[ch]. Server now performs
5551 keepalive with all connections.
5553 * Added silc_task_get_first function into lib/silcutil/silctask.c
5554 to return the timeout task with shortest timeout. There was a bug
5555 in task unregistration that caused problems. TODO has been
5556 updated to include that task system must be rewritten.
5558 * The client library will now resolve the client information when
5559 receiving JOIN notify from server for client that we know but
5560 have incomplete information.
5562 * Rewrote parts of silc_server_remove_from_channels and
5563 silc_server_remove_from_one_channel as they did not remove the
5564 channel in some circumstances even though they should've.
5566 * Encryption problem encountered in server:
5568 The LEAVE command used to send the Channel Key packet to the
5569 router immediately after generating it. However, the code
5570 had earlier sent Remove Channel user packet but not immediately,
5571 ie. it was put to queue. The order of packets in the router
5572 was that Channel Key packet was first and Remove Channel User
5573 packet was second, even though they were encrypted in the
5574 reverse order. For this reason, MAC check failed. Now, this
5575 is fixed by not sending the Channel Key packet immediately but
5576 putting it to queue. However, this is more fundamental problem:
5577 packets that are in queue should actually not be encrypted
5578 because packets that are sent immediately gets encrypted
5579 actually with wrong IV (and thus MAC check fails). So, packets
5580 that are in queue should be encrypted when they are sent to
5581 the wire and not when they put to the queue.
5583 However, the problem is that the current system has not been
5584 designed to work that way. Instead, the packet is encrypted
5585 as soon as possible and left to the queue. The queue is then
5586 just purged into wire. There won't be any fixes for this
5587 any time soon. So, the current semantic for packet sending
5590 o If you send packet to remote host and do not force the send
5591 (the packet will be in queue) then all subsequent packets to the
5592 same remote host must also be put to the queue. Only after the
5593 queue has been purged is it safe again to force the packet
5596 o If you send all packets immediately then it safe to send
5597 any of subsequent packets through the queue, however, after
5598 the first packet is put to queue then any subsequent packets
5599 must also be put to the queue.
5601 Follow these rules and everything works fine.
5603 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Added new function silc_server_remove_clients_by_server to
5606 remove all client entries from ID list when the server connection
5607 is lost. In this case it is also important to invalidate all
5608 client entires as they hold the invalid server entry. This
5609 fixes fatal bug when server has lost connection and will reconnect
5612 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Made some sanity checks to silc_server_daemonise like to check
5615 whether the requested user and group actually exists.
5617 * Added sanity check to SKE's silc_ske_responder_finish to check
5618 that the public and private key actually is valid.
5620 * Invalidate the client's nickname when receiving Replace ID
5621 packet and the Client ID is being replaced. This means that the
5622 server will query the nickname if someone needs it (client)
5625 * Sort the ID Cache in client library when the ID Cache data
5626 has changed (needs sorting).
5628 * Do not allow for SILC client to create several connections to
5629 several servers. The client does not support windows right now
5630 and generating multiple connections causes weird behaviour.
5632 Irssi-silc client does support windows and can handle several
5633 connections without problems, see: www.irssi.org and SILC plugin.
5635 * Fixed some places where client was added to the IDList. The
5636 rule of thumb is following (in order to get everything right):
5637 If the client is directly connected local client then the
5638 `connection' argument must be set and `router' argument must be
5639 NULL to silc_idlist_add_client function. If the client is not
5640 directly connected client then the `router' argument must
5641 bet set and the `connection' argument must be NULL to the
5642 silc_idlist_add_client function.
5644 * The funtion silc_server_packet_send_local_channel actually did
5645 not check whether the client was locally connected or not. It
5646 does that now. Fixed a bug related to LEAVE command.
5648 * Fixed Remove Channel User payload parsing bug in server's
5649 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5651 * The server's silc_server_save_channel_key now checks also the
5652 global ID list for the channel as it might not be in the local
5653 list. Fixed a bug related to LEAVE command.
5655 * Is this the end of the [<unknown>] buglet that has been lurking
5656 around for a long time? A little for loop fix in server's
5657 silc_server_command_whois_parse that is used by both IDENTIFY
5658 and WHOIS command. At least, this was a clear bug and a cause
5659 of one type of [<unknown>] buglet.
5661 * WHOIS and IDENTIFY commands call the function
5662 silc_server_command_[whois/identify]_check function even if
5663 we are not router server.
5665 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added --with-gmp configuration option. If set the GMP
5668 is always compiled in the SILC source tree. If not set then
5669 it is checked whether the system has the GMP3 installed. If
5670 it has then the GMP won't be compiled (the system's headers
5671 and library is used), if it doesn't have it then the GMP is
5672 compiled in the SILC source tree.
5674 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Changed RSA private exponent generation to what PKCS #1
5677 suggests. We try to find the smallest possible d by doing
5678 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5679 not security fix but optimization.
5681 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5683 * Added new config entry [Identity] to fork the server and run
5684 it as specific user and group. A patch from Bostik.
5686 * Imported Dotconf configuration library into lib/dotconf.
5687 This will be used to create the SILC configuration files later.
5688 It will appear in the distsribution after this commit.
5690 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * A big code auditing weekend happening. Auditing code for
5693 obvious mistakes, bugs and errors. Also, removing any code
5696 Removed files for being obsolete:
5698 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5699 inline in the file lib/silcutil/silcbuffer.h)
5701 o lib/silcutil/silcbufutil.c (the header has inline versions)
5703 Changed code to fix possible error conditions:
5705 o The buffer formatting routines now check that the destination
5706 buffer really has enough space to add the data. This applies for
5707 both buffer formatting and unformatting
5708 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5709 unformatting was changed to accomodate following rules:
5710 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5711 sent to the function while XXX_*STRING will not allocate or copy
5712 the data into the buffer. Instead it sets the pointer from the
5713 buffer into the pointer sent as argument (XXX_*STRING used to
5714 require that the pointer must be allocated already). This change
5715 makes this whole thing a bit more consistent and more optimized
5716 (note that the data returned in the unformatting with XXX_*STRING
5717 must not be freed now). The routines return now -1 on error.
5719 o Tried to find all code that use buffer_format and buffer_unformat
5720 and added return value checking to prevent formatting and
5721 especially unformatting errors and possible subsequent fatal
5724 o Changed ske->x and ske->KEY to mallocated pointers in
5725 lib/silcske/silcske.h. Fixed possible data and memory leak.
5727 o Added return value checking to all *_parse* functions. Fixed
5728 many memory leaks as well.
5730 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5731 so that buffer overflows would not happen. All code now also
5732 checks the return value as it can fail.
5734 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Added reconnection support to server if the normal server looses
5737 its connection to the router (for example if router is rebooted).
5738 The server performs normal reconnection strategy implemented
5739 to the server. Affected file silcd/server.c.
5741 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added new packet type SILC_PACKET_SET_MODE that is used to
5744 distribute the information about changed modes (for clients,
5745 channels and clients channel modes) to all routers in the
5746 network. Updated the protocol specification accordingly.
5748 Added functions into silcd/packet_send.c and
5749 silcd/packet_receive.c: silc_server_send_set_mode,
5750 silc_server_set_mode.
5752 Added new files silcmode.[ch] into lib/silccore that implements
5753 the encoding and decoding of Set Mode Payload. Added new type
5754 SilcSetModePayload. Moved the definitions of different modes
5755 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5757 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Oops, a little mistake in server's connection authentication
5760 protocol. The protocol is not ended with FAILURE but with
5761 SUCCESS if the authentication is Ok. :) Affected file is
5764 * Implemented NICK_CHANGE notify handling in server in the file
5765 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5766 the local clients on the channel. After the changing nickname
5767 in router environment snhould work and the [<unknown>] nickname
5768 should appear no more.
5770 The silc_server_replace_id function that receives the Replace ID
5771 payload now sends the NICK_CHANGE notify type also in the file
5772 silcd/packet_receive.c
5774 * Changed WHOIS and IDENTIFY command to support the maximum amount
5775 of arguments defined in protocol specs (3328 arguments). This
5776 fixed a bug that caused problems when there were more than three
5779 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Added extra parameter, command identifier, to the
5782 silc_client_send_command so that explicit command identifier
5785 Changed that ID list routines uses specific command identifier
5786 when sending WHOIS/IDENTIFY requests to the server so that they
5787 can be identified when the reply comes back.
5789 Affected files lib/silcclient/command.[ch],
5790 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5792 * Added `sender' argument to silc_server_packet_send_to_channel
5793 to indicaet the sender who originally sent the packet to us
5794 that we are now re-sending. Ignored if NULL. Affected file
5795 silcd/packet_send.[ch].
5797 * Added some server statistics support in silcd/server_internal.h
5798 SilcServerStatistics structure and around the server code. Also
5799 send some nice statistics information when client is connecting
5802 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Fixed channel ID decoding in server's JOIN command reply in
5805 silcd/command_reply.c
5807 * Fixed braodcasting of replace ID payload to not to send it if
5808 we are standalone server in silcd/packet_receive.c.
5810 * Fixed all channel message sending routines to not to send
5811 packets to clients that has router set, since they are routed
5812 separately in the same function earlier. Affects file
5813 silcd/packet_send.c and all channel packet sending functions.
5815 * In USERS reply, res_argv[i] are not allocated, the table
5816 is allocated. Thus changed that free the table, not its
5819 * In server's whois_check and identify_check if the client is
5820 locally connected do not send any WHOIS commands - they are not
5823 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Fixed some minor bugs in client when sending WHOIS command. The
5826 arguments was in wrong order.
5828 * Removed statis function add_to_channel from server in
5829 silcd/command.c that was previously used with the joining but
5832 * Tested USERS command in router environment successfully with two
5833 routers, two servers and two clients.
5835 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Reorganized the USERS command and command reply in client library
5838 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5839 When the command is given by user we register a pending command
5840 callback that will reprocess the command after the reply has been
5841 received from the server. When reprocessing the packet we then
5842 display the information. Thus, the USERS information is displayed
5843 now in the command callback instead of in the command reply
5844 callback. The processing of the command is same as previously
5845 when server has sent the command reply in the JOINing process.
5847 * Added to USERS command in silcd/command_reply.c to join the client,
5848 we didn't use to know about, to the channel after we've created
5849 a client entry for it. Also, for clienet we did know already still
5850 check whether it is on the channel or not and add it if not.
5852 * Removed silc_server_command_join_notify as the function and its
5855 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Changed the client's pending command handling to the same as the
5858 server's pending command handling. It is also now possible to
5859 execute command reply functions from other command reply
5860 function as the function callbacks for commands and command
5861 replies are one and same. The pending commands are not static
5862 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5863 in client connection context. Thus, pending commands are server
5864 connection specific as it is convenient.
5866 Changed the function silc_client_command_pending and
5867 silc_client_command_pending_del and added new function
5868 silc_client_command_pending_check. Removed the
5869 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5872 * Added cmd_ident, current command identifier, to the client
5873 connection context in lib/silcclient/client.h to keep track on
5874 command identifiers used in command sending. Client's command reply
5875 function handling now supports the mandatory command identifiers.
5877 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5878 funtions in client to fully support pending command callbacks.
5880 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5881 as one of the arguments to the application in the command reply
5884 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5885 before first releasing SILC but came back. Now it is removed again
5886 and should come back nomore. The FORWARDED flag was used only
5887 by the JOINing procedure by forwarding the command packet to router.
5888 Now, the JOINing procedure has been changed to more generic (due
5889 to various router environment issues) and FORWARDED is not needed
5890 anymore for anything. The protocol specification is yet to be
5893 Now, removed silc_server_packet_forward from server and the flag
5894 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5896 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Renamed NAMES command to USERS command. The NAMES was named that
5899 due to historical reasons. Now it is renamed. Also, rewrote
5900 parts of the USERS command. The nickname list is not sent anymore
5901 by the server. Only Client ID and mode lists are sent in the USERS
5902 command. Changed this also to the protocol specification.
5904 The client now resolves the names and stuff after it receives
5905 the USERS list from the server when joining to the channel.
5907 * WHOIS and IDENTIFY commands has been changed to support multiple
5908 Client ID's per command. One can now search for multiple users
5909 in the network by sending only one WHOIS or IDENTIFY command.
5910 Changed the code and the protocol specifications.
5912 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5913 uses silc_server_command_whois_parse to parse the request. */
5915 * If normal server, do not parse the WHOIS and IDENTIFY requests
5916 before sending it to the router. Saves some time.
5918 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5920 * Fixed JOIN command on client library. Wrong number of arguments
5921 used to crash the client.
5923 * Added silc_server_channel_has_global function to check whether
5924 channel has global users or not.
5926 * Added silc_server_channel_has_local function to check whether channel
5927 has locally connected clients on the channel.
5929 * The silc_server_remove_from_one_channel now checks whether the
5930 channel has global users or not after given client was removed from
5931 the channel. It also checks whether the channel has local clients
5932 on the channel anymore. If it does not have then the channel entry
5933 is removed as it is not needed anymore.
5935 * The silc_server_notify now checks on JOIN notify whether the joining
5936 client is one of locally connected or global. If it is global then
5937 the channel has now global users on the channel and that is marked
5938 to the channel entry. Also, it now saves the global client to
5939 global list who is joining and JOINs it to the channel. This is
5940 for normal server, that is.
5942 Changed silc_server_send_notify_on_channel,
5943 silc_server_packet_relay_to_channel and
5944 silc_server_packet_send_to_channel check if we are normal server
5945 and client has router set (ie. global client) do not send the
5946 message to that client, as it is already routed to our router.
5948 * Implemented LEAVE notify type handling in silc_server_notify
5951 * Tested LEAVE command in router environment successfully. Tested
5952 with two routers, two servers and two clients.
5956 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5958 * Implemented SIGNOFF notify type handling in silc_server_notify
5961 * silc_server_remove_id now removes the client entry from all channels
5962 it has joined and thusly sends SIGNOFF notify type.
5964 * Rewrote the NAMES list generation in server by removing two excess
5965 loops. The lists are created now inside one loop.
5967 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * silc_server_remove_channel_user checks now also global list
5970 for channel and client.
5972 * silc_server_new_channel_user checks now both local and global
5973 list for channel and client. Fixed a bug in client id decoding.
5974 Used to decode wrong buffer.
5976 * silc_server_channel_message checks now both local and global
5977 list for channel entry.
5979 * Tested channel joining (hence JOIN) in router environment
5980 successfully. Tested with two routers, two servers and two
5983 * Tested channel message sending in router environment successfully.
5985 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5987 * Added silc_server_save_channel_key into server.[ch] to save the
5988 received channel key in Channel Key payload processing. It is
5989 also used in JOIN command reply handling.
5991 Equivalent function silc_client_save_channel_key added into
5992 client.[ch] into client library.
5994 * Changed JOIN command reply to send information whether the channel
5995 was created or not (is existing already) and the channel key
5996 payload. Changed protocol specs accordingly.
5998 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5999 the request was sent by ID and not by nickname. Crashed on
6002 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6005 now correctly save the received data.
6007 * silc_server_free_sock_user_data now notifies routers in the
6008 network about entities leaving the network.
6010 At the same time implemented functions silc_server_remove_id
6011 and silc_server_send_remove_id to receive and send REMOVE_ID
6012 packets. The packet is used to notify routers in the network
6013 about leaving entities. The ID removed will become invalid in
6016 * Added function silc_idlist_del_server into server. Removes and
6017 free's server entry from ID list.
6019 * silc_server_private_message function now checks, if we are router,
6020 that the destination ID really is valid ID, naturally.
6022 * In router when NEW_ID packet is received (for new client) the
6023 hash of the Client ID is saved in the ID Cache but the
6024 client->nickname is set to NULL, instead of putting the hash
6027 IDENTIFY command now also checks that client->nickname must be
6028 valid. If it is not if will request the data from the server who
6029 owns the client. Added new function
6030 silc_server_command_identify_check.
6032 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6033 to set the command to already allocated Command Payload.
6035 * Tested private message sending in router environment with two
6036 routers, two servers and two clients. Fixed minor bugs and now
6039 * Fixed segfault from client's NAMES command. Used to crash if
6042 * Forwarded packets must not be routed even if it is not destined
6043 to the receiver. Changed server code comply with this.
6045 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Added `require_reverse_mapping' boolean value to ServerParams
6048 structure. If TRUE (not default) the server will require that
6049 the connecting host has fully qualified domain name.
6051 If the reverse mapping is not required and hostname could not be
6052 found the IP address is used as hostname.
6054 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Implemented version string checking to both client and server.
6057 The check is incomplete currently due to the abnormal version
6058 strings used in development version of SILC.
6060 * Changed all command functions in server to use the new
6063 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6065 * Changed char *data to unsigned char *data in ID Cache system to
6066 support binary data as ID Cache data. Changed code to support
6067 binary data in lib/silccore/idcache.c.
6069 * Renamed silc_server_packet_relay_command_reply to
6070 silc_server_command_reply as it is normal packet receiving
6071 function. Rewrote the function to accept command replys for
6072 servers and not only for clients.
6074 * Mark remote router always as registered server if we are connecting
6075 to it. Otherwise, commands sent by the router to us are ignored.
6077 * All ID List find routines now returns the ID Cache Entry pointer
6078 as well if requested.
6080 * WHOIS command works now in router environment, tested with two
6081 routers, two servers and two clients.
6083 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6084 in router environment (as it is almost equivalent to WHOIS) but
6085 hasn't been tested thoroughly. Added new functions:
6087 silc_server_command_identify_parse
6088 silc_server_command_identify_send_reply
6089 silc_server_command_identify_from_client
6090 silc_server_command_identify_from_server
6092 * Disabled route cache adding because adding two different ID's with
6093 same IP replaces the old cache entry thus giving wrong route.
6094 The entry->router->connection is always the fastest route anyway
6095 so route cache may not be needed. Of course, new routes maybe
6096 established after receiving the ID when the entry->router->connection
6097 might not be anymore the most optimal.
6099 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Add route cache for received ID for fast routing.
6103 * Added silc_server_packet_route to route received packet on router
6104 that is not destined to us.
6106 * Renamed silc_server_get_route to silc_server_route_get.
6108 * Added id_string and id_string_len fields into SilcServer to
6109 include encoded ServerID for fast comparing without excess
6110 encoding of the ID's.
6112 * Cleaned up WHOIS command on server side. Added following static
6115 silc_server_command_whois_parse
6116 silc_server_command_whois_check
6117 silc_server_command_whois_send_reply
6118 silc_server_command_whois_from_client
6119 silc_server_command_whois_from_server
6121 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6122 arguments in command replies. All command functions should be
6123 updated to use this macro.
6125 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Minor typo fixes on command reply handling on server.
6129 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Added silc_server_command_add_to_channel internal routine to add
6132 the client to the channel after router has created the channel and
6133 sent command reply to the server.
6135 * Added generic silc_server_send_command to send any command from
6138 * Use static buffer with ID rendering instead of duplicating data.
6140 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Fixed a channel user mode bug when joining to a channel server gave
6143 everybody channel founder rights, oops.
6145 * We mark ourselves as the router of the incoming server connection
6146 if we are router ourselves. This way we can check in some packet
6147 sending functions whether it is locally connected server. For
6148 incoming router connections we put NULL.
6150 * For router sending packets locally means now always sending the
6151 packet cell wide; to local clients and local servers. For normal
6152 server sending packet locally means sending it to only local
6155 * Fixed the JOIN command to really work in router environment. If the
6156 channel is created it is always created by the router. Router is
6157 also responsible of making the initial joining to the channel,
6158 sending JOIN notify to the sending server and distributing
6159 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6160 does not exist server doesn't do anything else but forward the
6161 command to the router which performs everything.
6163 * Added silc_server_send_channel_key function to send the Channel Key
6166 * Added silc_server_create_channel_key to create new channel key. The
6167 channel key is now re-generated everytime someone joins or leaves
6168 a channel, as protocol dictates. Note: channel->key_len is the
6171 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6174 packet_receive.[ch] to separate packet sending and receiving
6175 routines. The server.[ch] now includes everything else including
6176 actual packet processing (writing and reading data) and other
6179 Renamed silc_server_private_message_send_internal to
6180 silc_server_send_private_message. The routine is still though
6181 used only to relay private messages as server does not send
6182 private messages itself.
6184 Renamed silc_server_new_channel to silc_server_create_new_channel
6185 and added new function sicl_server_new_channel that handles the
6186 incoming New Channel packet. Added also new sending function
6187 silc_server_send_new_channel to send New Channel Payload.
6189 * Added new function silc_server_notify to process incoming notify
6190 packet to the server/router. Server may then relay the notify
6191 to clients if needed.
6193 * Added new function silc_server_new_channel_user to process incoming
6194 New Channel User packet. Router will redistribute the packet and
6195 send JOIN notify to its local clients and locally connected servers
6196 if needed. Normal server will send JOIN notify to its local client
6197 on same channel when received this packet. Added also corresponding
6198 sending function silc_server_send_new_channel_user to sent the
6201 * Added boolean route argument to send_notif_to_channel and
6202 packet_send_to_channel functions to attempt to route the packet
6203 if it is TRUE and send only locally if it is FALSE.
6205 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * silc_server_replace_id now broadcasts the received replace ID
6208 packet if it is not broadcast packet already. The router must
6209 broadcast to inform other routers about changed ID.
6211 * Added backpointer to server's router into SilcServer context in
6212 silcd/server_internal.h.
6214 * Fixed silc_server_packet_broadcast to send correct broadcast
6217 * The channel key is now distributed to the local client as soon
6218 as it is received from the router (in router environment) so that
6219 no other packet may be sent for the channel until client has
6222 * silc_server_remove_channel_user now broadcasts the received
6223 Remove Channel User packet if it is not broadcast packet already.
6224 The router must broadcast to inform other routers about removed
6227 * Added users field into SilcPacketContext that is a reference count
6228 of the context. One can increase the reference count by calling
6229 silc_packet_context_dup which is now changed to just increase the
6230 reference count instead of duplicating the data. The reference
6231 count is decresed by calling silc_packet_context_free that will
6232 free the data after the reference count hits zero.
6234 For now on the packet context and everything allocated into it
6235 (including the raw packet from network) must be freed by calling
6236 the new silc_packet_context_free function. Added also new function
6237 silc_packet_context_alloc that must be used now to allocate the
6238 context. This also means that if a routine is asynchronous from
6239 silc_[client/server]_packet_parse_type the packet context must
6240 be duplicated by calling silc_packet_context_dup. Otherwise it
6241 gets free'd after silc_[client/server]_packet_parse_type returns.
6242 Also, one must remember that if packet is duplicated then its
6243 reference count must be decresed by calling the free function as
6244 many times as it was duplicated.
6246 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6247 from both client and server.
6249 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Made joining to a channel working in router environment.
6253 * Cleaned up JOIN command on server side and create function
6254 silc_server_command_join_channel internal routine to make the
6257 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Changed silc_command_pending list to SilcDList. Also, added
6260 `ident' field to SilcServerCommandPending structure to identify
6261 the reply and to call correct callback.
6263 Added silc_server_command_pending_check function to replace the
6264 corresnponding macro. The silc_command_pending list is not
6267 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6268 to set identifier to previously allocated Command Payload. It
6269 is used to set identifier for command when resending Command
6272 * Added silc_command_payload_encode_payload to encode Command
6273 Payload buffer from SilcCommandPayload structure.
6275 * Added silc_argument_payload_encode_payload to encode Argument
6276 payload buffer from SilcArgumentPayload structure.
6278 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Changed WHOIS command to support router connection on server side.
6281 The whois request is always sent to router unless the server is
6282 standalone server. After server has received the reply from the
6283 router will it send the reply to the client.
6285 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6286 broadcast received broadcast packet. The function is used only
6287 by router. The broadcast packet is always sent to the router's
6290 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6291 render given ID to printable string, for log files for example.
6293 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6295 * Made basic router to router connections working. At least they
6296 can now connect to each other but nothing really works the way
6297 they are supposed - yet.
6299 * Added new initiator token to RouterConnection configuration
6300 file in silcd/serverconfig.[ch]. It is used to tell whether we
6301 are the initiator to the remote router or whether we'll expect
6302 the other end to connect.
6304 * Moved registering of listener task to silc_server_init, hence
6305 the server starts listenning as soon as it is run, even if it
6306 does not have connections to other routers. Let's see how well
6309 * Changed default connection retry timeouts for more suitable in
6312 * Removed cipher and such arguments from silc_idlist_add_client
6313 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6314 Added new function silc_idlist_add_data to add the keys and stuff
6317 * Added SilcIDListData structure and added it to SilcClientEntry
6318 and SilcServerEntry as their first field in the structure. This
6319 way we can explicitly cast the ID entries to the SilcIDListData
6320 structure and get common data for the entries. In past, we had
6321 to first check what type of connection it is and then cast it to
6322 correct ID entry type. Now, we can directly cast the opaque
6323 pointer to the SilcIDListData (no matter what ID entry it actually
6324 is) and get the data needed.
6326 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6329 in some circumstances even if threre were timeout tasks, though not
6330 IO tasks, but tasks anyway. Now fixed.
6332 * Defined SilcServerConnection structure to hold connection specific
6333 stuff about directly connected servers and routers. The definition
6334 is currently in silcd/server_internal.h. I thought about having
6335 a bit more important role fro this struct but for now it is used
6336 only when connecting to other server (or router actually).
6338 * Added connecting retry support in server when connecting to
6339 router(s). The retry feature implement exponential backoff
6340 algorithm. Also, added SilcServerParams structure to hold default
6341 parameters for server. For now, it include these retry settings
6342 and are hard coded. After server is moded to be as Silc Server
6343 Library this structure will be more important.
6345 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Changed client librarys channel->clients table to SilcList and
6348 changed code accordingly.
6350 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6352 * Changed client's channel table to SilcList and changed code
6353 accordingly. Also changed SilcChannelClientEntry to include back-
6354 pointer to the channel so that client entry can use that structure
6355 as list as well and we have fast cross-reference to the channel.
6356 This change dramatically decreased the complexity of channel
6357 handling with client entry and vice versa (removed one extra
6358 loop when searching for channel entry from many functions).
6360 * Changed server->sim from table to SilcDList and changed code
6363 * NAMES command can now be used from user interface. It will show
6364 the user list on the channel, neatly.
6366 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6367 Code now saves realname of the user if it becomes available.
6369 * Renamed configure.in to configure.in.pre and made ./prepare
6370 script to automatically add correct version string to
6371 configure.in which it creates from configure.in.pre.
6373 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * NAMES command reply now shows users mode with the nickname when
6378 * Moved silc_client_ch[u]mode[_char] functions from
6379 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6380 place sucks, they are utility functions and should be in some
6383 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6385 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6388 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Added TRQ (efficient deque and list library) into lib/trq. This is
6393 a very good list library that is currently used in the SILC. Defined
6394 SilcList API over the library because I didn't like the API very
6395 much. See lib/trq/silclist.h for the API and examples of how to
6396 use the API. Fixed various places in the code to use the new
6397 SilcList API. The SilcList is meant for lists that has a structure
6398 already defined as a list. It is not suitable to add just some
6399 context to the list (in TRQ, the context is the list actually).
6401 So, I defined SilcDList that can be used for the purpose where
6402 predefined list structure does not exit. This can be used as
6403 such list. Now some context just can be added to the SilcDList.
6404 Currently this list is not used in the SILC just yet, though there
6405 are a lot places where this can replace dynamically allocated
6406 tables and I will fix these places, later, to use SilcDList.
6407 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6408 and use TRQ internally).
6410 Also fixed some annoying warning messages that the original TRQ
6411 code generated. Also minor changes to TRQ's Makefile.in.
6413 * Added support for querying by Client ID to both WHOIS and
6414 IDENTIFY commands into server, as required by the protocol.
6416 * Removed method function pointers from SilcBuffer structure. They
6417 weren't used to anything and just increased the context size for
6418 no good reason. This change also made silc_buffer_alloc and
6419 silc_buffer_free functions inline functions.
6421 * Disabled command flooding detection support until it's fixed so
6422 that it accepts commands in but does not execute them more than once
6425 * Added silc_net_localhost(), to return local hostname, into
6426 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6427 that must be initialized before calling silc_client_init.
6429 * Added new function: silc_server_send_notify_on_channels to send
6430 notify messages to all channels client has joined. It is assured
6431 that the message is sent only once per client.
6433 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6434 lib/silcutil/silcutil.[ch] as silc_format function. The new
6435 function is generic and is used by server as well, not only by
6436 the logging routines.
6438 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6439 the provided version string was not acceptable. Added new function:
6440 silc_ske_check_version into lib/silcske/silcske.h. The function
6441 must be implemented by the application (client or server) and it
6442 does not reside in the SKE library. The function checks the version
6443 string remote end sent.
6445 * Added back pointers (to opaque context and to SilcSocketConnection)
6446 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6448 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6449 duplicate packet context structure.
6451 * Changed `notify' client operation to send same arguments as client
6452 receives from server except for ID's. ID's are mapped to correct
6453 ID entry and that is returned. Also, if channel entry is not sent
6454 by server but the notify is for channel the channel entry is sent
6455 to application (otherwise application doesn't know that it is for
6456 channel (library gets it from packet's Destination ID)).
6458 * Added silc_client_remove_from_channels into client library to
6459 remove a client from all channels it has joined to. Used when
6460 received SIGNOFF notify from server. Added also new function
6461 silc_client_replace_from_channels to replace old ID entry with
6462 new ID entry on all channels. Used when received NICK_CHANGE
6465 * Fixed ID Cache list handling in silc_idlist_get_client in
6466 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6467 to get (or query) client by ID.
6469 * Updated TODO list.
6471 * Added connection authentication status message defined by the
6472 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6473 support for these into the code in client and server side.
6475 * Added generic function silc_client_send_command to send any command
6476 with variable argument list. Application should use this function
6477 to send commands if the command functions provided by the library
6478 does not suite for the application's user interface needs.
6480 * Added new `failure' client operation. Application is notified about
6481 received failure packet if client is executing a protocol. In this
6482 case the protocol's execution has failed.
6484 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6485 is required by the protocol.
6487 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6488 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6491 * Added status flag to SilcSKE object to indicate realtime status
6492 of the SKE protocol.
6494 * Application receives now exactly same command reply arguments as
6495 the library receives from server. However, if ID is received the
6496 corresponding ID entry is returned to the application (eg. Client
6497 ID is mapped to correct SilcClientEntry entry and that is returned).
6498 Changed command_reply client operation due to this change.
6500 * Changed all ID's in commands and in command replys as ID Payloads.
6501 Change affected both client and server side codes.
6503 All ID's sent in SILC network (with execption of ID's in SILC
6504 Packet header) are sent in ID Payload to support variable length
6507 * Server now notifies nick changes and notifies all clients on
6508 the channels about the new nickname (about the new Client ID,
6511 * Implemented CMODE command to change channel modes. Supports all
6512 channel modes defined by the protocol specs except ban and invite
6513 lists. (Also, private channel key mode is supported but support for
6514 setting private channel key in client is missing, thus, this mode
6515 has no effect on client side (except that server requires that the
6516 client uses private channel key and normal channel traffic does not
6519 Also, invite mode works per se, but INVITE command does not work
6520 yet correctly, so you can set channel as invite only channel but
6521 inviting clients to the channel does not work (it is yet to be
6522 thought what's the best way to do it).
6524 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6525 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6526 Implemented CUMODE command to change user's mode on the channel.
6527 Supports all modes defined by the protocol specs.
6529 * Added NAMES command reply to return users modes on the channel.
6531 * Removed unnecessary and slow ciphers from lib/silccrypt.
6533 * Set SO_KEEPALIVE option to connection sockets by default.
6535 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6537 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6538 redefined the Notify Payload into protocol specs.
6540 * Added silc_id_payload_parse_id to get ID directly from raw
6543 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6546 accept searching by Client ID as well.
6548 * Added support for LEAVE and SIGNOFF notify types in client library.
6550 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6551 to parse ID Payload from raw data.
6553 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Added flags parameter into silc_ske_assemble_security_properties
6556 function in lib/silcske/silcske.[ch].
6558 * Changed notify client operation to fit better for notify messages
6559 sent by server. The notify payload received from server is now
6560 passed to the application (after parsing it to SilcNotifyPayload).
6561 It is application's responsibility to retrieve the arguments
6562 from the payload and show the message the way it wants. The message
6563 sent by server is implementation specific.
6565 * Changed public keys to comply with the protocol specification.
6566 Old public keys are not supported anymore and are not compatible.
6568 * Removed nickname from Channel Payload as the latest draft removed
6569 it. The client must resolve the nickname from the NAMES command
6570 reply received when it joined the channel.
6572 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6574 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Fixed some errors in protocol specification drafts.
6578 * Created lib/silccore/silcnotify.c to implement Notify Payload
6579 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6580 generic payloads described by protocol specifications. The file
6581 includes implementations for ID Payload and Argument Payload.
6583 * Changed Command Payload implementation to use the new Argument
6584 Payload. Changed command_xxxx_payload to command_payload_xxxx
6585 to comply with SILC coding conventions.
6587 * Added suppport for Argument Payload handling in Notify Payload
6588 implementation as protocol requires it. Added the new support
6589 into server and client lib as well.
6591 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Added support for multiple nicknames on same channel. [n] is
6594 added locally to the nickname if there are more than one same
6595 nicknames on the channel.
6597 * Server now sends all nicknames that matched WHOIS request.
6598 Client also shows the list received from server.
6600 * Added TOPIC command to client side. User can now set and show
6601 current topic on channel.
6603 * Added MOTD command to client and server. Also, server sends the
6604 motd when client connects to the server.
6606 * Changed version strings to comply ISO 8601.
6608 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Fixed protocol error handling in client library. It should now
6611 cope even if the SKE fails for some reason.
6613 * Made new protocol specification drafts for submitting to IETF.
6615 * Implemented TOPIC command to server in silcd/command.c.
6617 * Added two new notify types into lib/silccore/silcnotify.h:
6618 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6619 notify nickname change and topic setting/change on a channel.
6621 * API change of command_reply operation in client library. The
6622 application gets now the status type received from server as well.
6624 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6628 * Cras fixed and optimized the packet handling even further and
6629 it should work now. Minor change to the prototype of function
6630 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6632 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Added new function into lib/silcutil/silcschedule.[ch]:
6635 silc_schedule_with_fd to select() a specified fd. The function
6636 returns after timeout expires or data arrives or goes. The
6637 function is used by packet routines to wait that all data is
6638 received from network.
6640 * Fixed data reading from network in lib/silccore/silcpacket.c.
6641 The code now assures that all data is read from the fd and then
6642 continues packet processing. This was a bug fix since the code
6643 used to drop some data in some circumstances.
6645 * Added new function into lib/silcclient/client.[ch]:
6646 silc_client_start_key_exchange to start key exchange after
6647 connection has been established to server. The code internally
6648 now uses this funtion but its main purpose was to provide it
6649 for applications that perform their own connecting. After
6650 application has created a connection it merely calls this
6651 function to start the key exchange between client and server.
6652 The library takes care of everything else after that.
6654 Updated also lib/silcclient/README to explain the usage of
6657 * Do not send to application information that connection has
6658 been established. Application gets notified it by connect
6661 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Applied cras's patch to add silc_schedule_one function. The
6664 function runs scheduler once and returns.
6666 * Fixed the scheduler after cras messed it up. The timeout
6667 handling works now as it's supposed to work.
6669 * Added into lib/silccore/ silcnotify.h to include notify
6670 message types support. Changed silc_server_send_notify*
6671 functions, in server.[ch], to support those new notify types.
6672 Added the support for the notify types into client library,
6673 as well. Added new notify client operation into ops.h in
6676 * Changed silc_server_packet_send_to_channel to send normal
6677 packets instead of just channel message packets. The function
6678 is now used to send the notify packets to channels. It is not
6679 used to send channel message packets anymore, as server never
6682 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6683 va_arg()s as it seems to require it nowadays. I guess, if SILC
6684 is compiled with older va_arg() the new code should work anyway.
6686 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Splitted core library. Core library (lib/silccore) includes
6689 now only SILC protocol specific core (and common) components.
6690 Created new utility library (lib/silcutil) that includes more
6691 generic purpose stuff. The stuff for util library was taken
6692 from the old core library. This was minor and easy split.
6694 * Created SILC Client Library (lib/silcclient) that includes
6695 implementation of the SILC client without user interface. This
6696 was major move from silc/ directory. The code has been changed
6697 so that it is transparent towards the user interface. The
6698 silc/ directory includes now the same user interface as before
6699 and it uses the new client library. Read lib/silcclient/README.
6700 Basicly, the client library performs everything else related
6701 to SILC except user interface handling. Also, configuration
6702 files are considered to be part of user interface and library
6703 does not handle them.
6705 This change also changed a lot of structures, function naming etc.
6706 Most important change was that SilcClientWindow object was
6707 renamed to SilcClientConnection in the client library. Created
6708 also new file lib/silcclient/ops.h. Also added new files
6709 silc/local_command.[ch] and silc/client_ops.[ch].
6711 All these changes were made to make it easier for user interface
6712 designers to create what ever user interface for the SILC client
6715 It is also expected that the server will be moved to lib
6716 directory as well and SILC Server Library will be created;
6717 sometimes in the future.
6719 * Removed Local commands from lib/silccore/silccommand.h as
6720 they are application specific and new client library does not
6721 handle any of those anymore.
6723 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6724 old client implementation in silc/.
6726 * Added support for callback functions in SILC_LOG_* macros.
6727 Application can now set its own callbacks that will be called
6728 instead of using the default functions that will always print
6729 the debug messages to stderr (or stdout). Also, debugging can
6730 now be disabled by setting silc_debug to FALSE and re-enabled by
6731 setting it to TRUE. Note, that logging will still work even
6732 if debugging is disabled.
6734 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6735 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6736 silc_log_reset_debug_callbacks.
6738 * To enable debugging in silc client one must give now -d
6739 option on command line.
6741 * Changed silc_schedule_init to automatically allocate task queues
6742 if they are not allocated before calling it.
6744 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Added GMP 3.1 into math library.
6748 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6751 a channel in SILC network. The packet is used by servers and
6752 routers to notify other routers that user has left a channel.
6753 This little feature was missing until now. Added the feature
6754 to protocol specification as well.
6756 Added functions: silc_server_send_remove_channel_user and
6757 silc_server_remove_channel_user into server.[ch].
6759 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6760 lib/silccore/silcpacket.h. However, they are not implemented
6763 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Fixed joining to a channel and sending channel messages
6766 between server and router. The channel message sending should
6767 now work inside a cell.
6769 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Fixed the private message sending between server and router.
6772 The private message sending should now work inside a cell.
6774 * Added silc_server_replace_id into server.[ch] to replace
6775 existing ID in the SILC network.
6777 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6778 and silc_idlist_replace_server_id into idlist.[ch] in server.
6780 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Fixed the server to server connections. Server can again now
6783 connect to router. Router to router connections probably does
6786 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6788 * Added dynamic protocol registering support. Now protocols can
6789 registered and unregistered on the fly. Patch by cras.
6791 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * Added lib/contrib directory to hold routines that some platforms
6794 don't have but are needed by SILC.
6796 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6797 into lin/contrib to provide getopt() and getopt_long() for
6798 those who don't have it.
6800 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Added AWAY command to client. When away message is set and
6803 client receives a private message packet the client automatically
6804 replies to the sender with the away message.
6806 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6807 bug seemed to be the cause of recent problems when compiling
6810 * Added version detection support to SKE protocol specification
6811 and added the new changes to the SKE implementation as well.
6812 There were other minor changes in the SKE protocol as well.
6814 Many changes in lib/silcske/silcske.[ch] and in
6815 lib/silcske/payload.[ch].
6817 * Added ^U functionality, clear input line. Patch from cras.
6819 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Mainly small bugfixes on core library. Fixed some debugging
6822 logging and buffer overflow in silclog.c.
6824 * Updated config.sub and config.guess on the distribution tree.
6826 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added command lagging support in server. Client may execute
6829 commands now only once in two seconds.
6831 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Optimized packet reception. MAC computation and checking is now
6834 also more optimized. A lot previously duplicated code is now
6835 used as generic by both client and server.
6837 * Fixed key pair generation in clientutil.c
6839 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added into lib/silccore/silcbufutil.[ch] new function;
6842 silc_buffer_realloc.
6844 * Moved generic packet sending/encryption functions to
6845 lib/silccore/silcpacket.[ch] from client and server. Some
6846 rewriting of the functions.
6848 * Moved all generic packet reception/decryption functions to
6849 lib/silccore/silcpacket.[ch] from client and server. The
6850 packet processing is now much cleaner in both client and server.
6851 These were major changes in both client and server.
6853 * Created many common functions in server to do packet sending.
6854 Previously code were duplicated a lot, this has been removed
6857 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Rewrote major parts of the ID cache system. Don't know
6860 whether it is better now or not but at least the API is more
6863 * Major rewrite on ID cache stuff on client because of the ID
6864 cache API changes. Added idlist.c to client.
6866 * Also major rewrite on ID cache stuff on server as well.
6867 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6868 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6869 in hand, instead they are all put into the ID cache system now.
6870 All server_idlist_* routines uses ID cache now instead of
6871 traversing its own lists (those lists does not exist anymore).
6872 SilcIDList though still exists. Also, SilcXXXEntry's are
6875 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * Finally made the SKE implementation compliant to the protocol
6878 specification. All mp integers are now binary encoded as
6879 opposed being HEX encoded.
6881 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6884 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6885 functions: silc_[encode/decode]_pem. Also added function
6886 silc_encode_pem_file to PEM encode with newlines ('\n') for
6889 * SILC public keys are now encoded either PEM or binary. Same
6890 option is for private keys as well. By default private keys
6891 are binary encoded and public keys PEM encoded. Silly HEX
6892 encoding were removed.
6894 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6895 function to create fingerprints.
6897 * Fixed a bug in SHA1; does not change the original data anymore.
6899 * Partly implemented INFO command on client and server side.
6900 Fixed CLEAR command. Changes to SERVER command; show current
6901 server(s) when giving command without arguments. Added
6902 VERSION command to client.
6904 * Added check to server that unregistered connections cannot
6905 execute commands (unless it is specificly allowed).
6907 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Fixed screen refresh.
6911 * Fixed channel joining bug from client. On some circumstances
6912 client tried to join to a channel it had already joined.
6914 * Added public key verification process into client's protocol.c.
6915 The client now verifies the public key from user and saves
6916 it into ~./silc/serverkeys/ directory.
6918 Added into: clientutil.[ch]: silc_client_verify_server_key.
6920 * Changed SKE protocol's silc_ske_initiator_finish function
6921 to accept callback function that verifies the received public
6922 key. Removed old silc_ske_verify_public_key function.
6924 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6927 silc_pkcs_private_key[_data]_set.
6929 * Made the password and public authentication more cleaner in
6930 server's protocol.c.
6932 * Removed historic and obsolete protocol `channel_auth' from
6933 both client and server.
6935 * Removed wrong way of sending command status messages from
6936 server to client in server's command.c. The old way violated
6937 protocol specification.
6939 Changes to silccore/silccommand.[ch]: removed
6940 silc_command_encode_status_payload -> not needed anymore,
6941 changed silc_command_encode_payload_va to accept extra
6942 argument on variable argument list. The argument type must
6943 now be provided to the function. Also, added new function:
6944 silc_command_encode_reply_payload_va which is same as
6945 normal command_encode_payload_va except command status type
6946 is provided as extra argument.
6948 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Added ~./silc directory handling. The directory includes the
6951 public and private keys for the client.
6953 Added silc_client_check_silc_dir, silc_client_create_identifier
6954 and silc_client_load_keys.
6956 * Implemented SILC protocol compliant public key. Added public
6957 and private key saving to and loading from files.
6959 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6960 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6961 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6962 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6963 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6965 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6966 silc_pkcs_load_[public/private]_key.
6968 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Added silc_server_get_route (route.[ch]) to get connection
6971 data for the fastest route for given ID.
6973 * Implemented INVITE command on client and server. The command
6974 were re-defined in the SILC Protocol Specification and the
6975 implementation now complies with the specification.
6977 * Implemented PING command on client and server.
6979 * Implemented NAMES command on client and server. The server side
6980 supports currently only normal server not router server yet.
6981 Some changes to NAMES definition in SILC protocol specification.
6983 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6985 * Implemented LEAVE command on client and server.
6987 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6988 again. This change was made to the protocol as well. Server
6989 should not violate the protocol specification anymore.
6991 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6994 was tested. SOCKS4 was not but should work anyway.
