22 as part of Toolkit documentation.
24 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
26 * Fixed CUMODE_CHANGE notify handling to change the mode of
27 correct client. Affected file lib/silcclient/client_notify.c.
29 * Make silc_rng_alloc fail if it cannot allocate the sha1
30 hash algorithm. Affected file lib/silccrypt/silcrng.c.
32 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
34 * Fixed the file transfer's key agreement payload to include
35 zero port also if the hostname is NULL because it could not
38 Call file transfer monitor callback now also if error occurs
39 during key agreement protocol.
41 Changed the silc_client_file_send interface to return the
42 SilcClientFileError instead of session id. The session ID
43 is returned into pointer provided as argument.
45 Check that the file exists locally before sending the
46 file transfer request at all.
48 Affected file lib/silcclient/client_ftp.c, silcapi.h.
50 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
51 error than can occur while key agreement protocol. Affected
52 file lib/silcclient/silcapi.h.

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

77 Affected file lib/silcutil/silcnet.c.
79 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Fixed a bug in hash table internal routine for traversing
82 the table with foreach callback. The current entry may
83 become invalid in the callback but it was referenced after
84 the callback returned.
86 Do not allow auto rehashing of hash table during the
87 silc_hash_table_foreach operation, for same reasons as it is
88 not allowed for SilcHashTableList. Affected files are
89 lib/silcutil/silchashtable.[ch].
91 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
93 * Defined DLLAPI into silcincludes.h and silcwin32.h for
94 Win32 DLL. extern's in header files are now declared with
97 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Fixed private message handling. It used some old code that
100 caused the client to crash. Affecte file is
101 lib/silcclient/client_prvmsg.c.
103 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Added function silc_client_add_channel,
106 silc_client_replace_channel_id, and removed functions
107 silc_client_new_channel_id and silc_idlist_get_channel_by_id
110 * Added cross reference of the joined channels to the
111 SilcClientEntry, and changed the SilcChannelEntry's
112 users list to SilcHashTable. The affected files are
113 lib/silcclient/idlist.[ch].
115 * Fixed a bug in hash table tarversing. While the hash table
116 is traversed with SilcHashTableList the table must not be
117 rehashed. It is now guaranteed that auto rehashable tables
118 are not rehashed while tarversing the list. Also defined that
119 silc_hash_table_rehash must not be called while tarversing
120 the table. Added function silc_hash_table_list_reset that must
121 be called after the tarversing is over. The affected files are
122 lib/silcutil/silchashtable.[ch].
124 * Changed all hash table traversing to call the new
125 silc_hash_table_list_reset in server and in client library.
127 * Added function silc_client_on_channel to return the
128 SilcChannelUser entry if the specified client entry is joined
129 on the specified channel. This is exported to application as
130 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
132 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
134 * Fixed founder regaining problem with JOIN command on normal
135 server. The notify for mode change must be sent always and
136 not only if !cmd->pending. Affected file silcd/command.c.
138 * Fixed the WHOWAS command's reply sending to support the
139 lists correctly. Affected file silcd/command.c.
141 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
143 * When sending JOIN command to router for processing the
144 sender's old command identifier was not saved back to the
145 sender's command context, fixed now. The affected file is
148 * Create the key in JOIN command of the router did not return
149 the channel key, added check for this. Affected file is
152 * Fixed a channel ID update bug in JOIN command reply. Do
153 not directly upgrade the ID but call the function
154 silc_idlist_replace_channel_id if the ID was changed.
155 Affected file silcd/command_reply.c.
157 * Fixed memory leaks from command calling if it would fail.
158 Affected file silcd/command.c.
160 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

164 Memory leak fixes around libaries, irssi window resize fix,
165 new silclist.h and silcdlist.h, all extern inline changed to
168 * Removed dotconf from lib/dotconf, not needed anymore.
170 * Removed TRQ from lib/trq, not needed anymore.
172 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
173 with server connections. Later this will be configurable
174 in config file after new config file is done. Affected file
177 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
179 * Fixed a crash in server related to channel announcements.
180 Affected file silcd/server.c.
182 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
184 * Fixed memory leaks in silc_server_create_new_channel*
185 functions. Affected file silcd/server.c.
187 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
188 which ID was changed. This way the router will send the
189 user list for the channel again, and server won't be in
190 desync in some rare circumstances. Affected file is
191 silcd/packet_receive.c.
193 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
195 * Check for NULL socket pointer in the function
196 silc_server_packet_send_to_channel_real. Affected file
199 * Fixed the BAN notify handling to correctly remove ban
200 list. Affected file silcd/packet_receive.c.
202 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
204 * Fixed some header addition to Toolkit distribution in
205 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
207 * Added lib/silcclient/client_ops_example.h as an template
208 file for application programmers to quickly start using
209 the SilcClientOperation functions in their application.
210 Updated the lib/silcclient/README as well to tell about this
211 nice file made available.
213 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
215 * Call silc_server_remove_from_channels when removing client
216 entry when NO_SUCH_CLIENT_ID was received. Affected file
217 is silcd/command_reply.c.
219 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Added server & router operator statistics updating. Affected
222 file silcd/packet_receive.c and silcd/command.c.
224 * Fixed the SERVER_SIGNOFF notify handling on normal server
225 not to save the history information for clients. Same was
226 fixed earlier in remove_clients_by_server function, but not
227 here. Affected file silcd/packet_receive.c.
229 * Raised the default connection-retry count from 4 to 7 in
230 server. Affected file silcd/server.h.
232 * Cancel any possible reconnect timeouts when we start the
233 key exchange. Affected file silcd/server.c.
235 * Do not reconnect on connection failure when SCONNECT was
236 given. Affected files silcd/server.[ch].
238 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
240 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
242 * Fixed the NICK command to always give the unformatted
243 nickname to the one giving the NICK command. If unformatted
244 nickname is cached already it will be formatted and the
245 local entry will always get the unformatted nickname.
246 Affected file lib/silcclient/idlist.c.
248 * Fixed some double frees from client library commands.
249 Affected file is lib/silcclient/command.c.
251 * Fixed CUMODE command in server to assure that no one can
252 change founder's mode than the founder itself, there was a
253 little bug. Affected file silcd/command.c.
255 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Removed the SilcClientCommandDestructor from the client
258 libary, it is not needed anymore. Affected files are
259 lib/silcclient/silcapi.h, command[_reply].[ch],
260 client_notify, idlist.c.
262 * Fixed GETKEY command to first resolve client, and then
263 resolve the server only if the client was not found, instead
264 of resolving both at the same time. Affected file is
265 lib/silcclient/command.c.
267 * Added silc_client_start_key_exchange_cb and lookup the
268 remote hostname and IP address before starting the key
269 exchange with server. The affected file is
270 lib/silcclient/client.c.
272 * The server's public key is now saved using the IP address
273 of the server and not the servername for the filename.
274 The hostname public key filename is checked as an fall back
275 method if the IP address based filename is not found.
277 Fixed the GETKEY command to save the fetched server key
280 Print the remote server's hostname now when new key is
281 received during connection process. Affected file is
282 irssi/src/silc/core/client_ops.c.
284 * Return always our own public key to the client if it asks
285 for it with GETKEY command. Affected file silcd/command.c.
287 * Removed the use_auto_addr variable from default config
288 file since it was in wrong section. Affected file is
291 * Fixed TOPIC_CHANGE notification to not route it when it
292 was sent using silc_server_send_notify_to_channel function.
293 Affected file silcd/command.c.
295 * Fixed silc_server_send_notify_kicked to send the kicker's
296 Client ID also, it was missing. Affected files are
297 silcd/command.c, silcd/packet_send.[ch].
299 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
301 * Do not save client history information in SERVER_SIGNOFF.
302 Fixes the bug in normal server that it does not detect
303 the client becoming valid after the server becomes back
304 online. Affected file silcd/server_util.c.
306 * Added `sock_error' field into the SilcSocketConnection
307 context. When error occurs during socket operation (read
308 or write) the error is saved. Added also new function
309 silc_socket_get_error to return human readable socket error
310 message. Affected files are lib/silcutil/silcsockconn.[ch],
311 lib/silcutil/unix/silcunixsockconn.c, and
312 lib/silcutil/win32/silcwin32sockconn.c.
314 * The server now prints the socket error message in the
315 signoff for client. Affected file silcd/server.c.
317 * Fixed the `created' channel information sending from router
318 to server in JOIN command. Checks now whether the channel
319 really was created or not and set it according that.
321 Fixed the JOIN command to use the client entry's current
322 ID during the joining procedure instead of the one it sent
323 in the command (it is checked though), since it can change
324 between the packet processing and command processing, and
325 would just case unnecessary pain in the client end. Affected
326 file silcd/command.c.
328 * Fixed a channel key payload sending to use correct channel
329 ID when the server was forced to change the channel's ID by
330 router. Router sent the key payload with the old Channel ID.
331 Affected file silcd/packet_receive.c.
333 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Call silc_server_save_channel_key only if the key payload
336 was provided in the JOIN command's command reply. Affected
337 file silcd/command_reply.c.
339 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
341 * Fixed silc_mp_sizeinbase to return the value correctly with
342 MPI. Affected file lib/silcmath/mp_mpi.c.
344 * Fixed the stop_server signal to correctly stop the scheduler
345 and gracefully stop the server when SIGTERM or SIGINT signals
346 are received. Affected file silcd/silcd.c.
348 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
350 * Simple handling of TERM and HUP signals. Also added some log
351 flushing call around. Affected file is
354 * Fixed small bugs in silclog.c. Now buffering output will take
355 effect after 10 seconds since startup: This will ensure that
356 no important startup messages are lost. Also output redirection
357 will preserve original format ([Date] [Type] message).
358 Affected file is lib/silcutil/silclog.c.
360 * Added two options to the config file, in the logging section:
361 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
362 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
364 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
366 * Do not print the warning about log files not being initialized
367 more than once to avoid excess logging. Affected file is
368 lib/silcutil/silclog.c.
370 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
371 the SIM copying in make install in Makefile.am.pre.
373 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
375 * Rewritten silclog APIs. Globally interesting changes follows:
376 silc_log_set_files() changed to silc_log_set_file().
377 silc_log_set_callbacks() changed to silc_log_set_callback().
378 ROBOdoc documented silclog header file.
379 SilcLogCb now returns bool to wether inihibit the default
380 handler or not (to keep the old behaviour return always TRUE).
381 The new APIs should also fix the problem of the
382 silcd_error.log file that was written in the current directory.
385 Log files streams will remain opened after silc_log_set_file()
386 call, means less CPU usage notably on high traffic servers.
387 File streams are now full buffered, and flushed to the disk
388 every 5 minutes, lesses HD activity and CPU usage.
389 Messages can be redirected, allowing admins to configure
390 one single logfile for all server messages.
391 the silc_log_quick global variable to activate fast-logging.
392 Affected files lib/silcutil/silclog.[ch]
394 * Changed some code to conform new silclog APIs. Affected
395 files are doc/example_silcd.conf.in, silcd/server.c
396 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
399 * Fixed a memory leak that could occur in some situations.
400 Affected file silcd/serverconfig.c.
402 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
404 * Added the silc_client_del_client to remove the client from
405 all channels as well. Affected file lib/silcclient/idlist.c.
407 * Fixed the client library to correctly remove the client
408 from all channels when the client entry is being destroyed.
409 Affected file lib/silcclient/client_notify.c, command.c.
411 * Added auto-nicking support to the client library. If the
412 applicatio now sets client->nickname it will be sent to the
413 server after connecting by the library. This way for example
414 SILCNICK (or IRCNICK) environment variables will have effect
415 and always change the nickname automatically to whatever
416 it is wanted. Affected file lib/silcclient/client.[ch].
418 * Renamed silc_server_command_bad_chars to the
419 silc_server_name_bad_chars and moved it to the
420 silcd/server_util.[ch]. Added also new function
421 silc_server_name_modify_bad to return nickname that
422 includes bad characters as new nickname without those
423 bad characters. This check and modify is now used in
424 silc_server_new_client when the username is initially set
425 as nickname, so it must be checked to be valid nickname.
426 Affected file silcd/packet_receive.c.
428 * The nickname length is now taken from the packet for real
429 and not trusted to strlen() since it clearly can return
430 wrong length for nickname including bad characters. This
431 also applies to channel names. Affected file silcd/command.c.
433 * Removed the lib/silcsilm/modules directory. Modules are now
434 compiled into the lib/silcsim. Fixed the copying of the
435 modules to follow symbolic links in Makefile.am.pre.
437 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Fixed silc_string_regexify list creation. Fixes bugs with
440 BAN and INVITE commands in server. The affected file is
441 lib/silcutil/unix/silcunixutil.c.
443 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Removed the command destructor entirely from the server's
446 command and command reply routines. It is not needed, and
447 its usage was buggy and caused crashes. Affected files are
448 silcd/command[_reply].[ch].
450 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Cancel protocol and NULL sock->protocol if timeout
453 occurred during protocol. Affected file silcd/server.c.
455 * Cancel protocol timeouts always before calling the final
456 callback, to assure that after final callback is called
457 no other state will be called for the protocol anymore.
458 Affected file silcd/protocol.c.
460 * Print error log if incoming connection configuration could
461 not be found. Affected file silcd/server.c.
463 * Fixed JOIN command to correctly save the founder mode
464 to the client on normal SILC server, when the channel
465 was created by the router. Affected file silcd/command.c.
467 * Fixed LIST command (hopefully) to send correct reply
468 packets. Affected file silcd/command.c.
470 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
472 * The silc_packet_receive_process now returns FALSE if the
473 read data was invalid packet, and TRUE if it was ok.
475 The server now checks that if unauthenticated connection
476 sends data and its processing fails the server will close
477 the connection since it could be a malicious flooder.
479 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
481 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
483 * Make sure the warning about error opening a log file is
484 printed only once and not everytime it fails (produces
485 too much useless log). Affected file lib/silcutil/silclog.c.
487 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
489 * Made the silc_server_daemonise() function more readable.
490 Affected file silcd/server.c.
492 * Pid file is now optional, the user may comment it out from
493 the config file. Removed define SILC_SERVER_PID_FILE, we
494 don't need a default any longer. Affected file
495 configure.in.pre, lib/Makefile.am.pre.
497 * Make some use of the pid file. The server now dies at startup
498 if it detects a valid pid file on his path. The server would
499 die anyway in this circumstance, because of the bind() failure.
500 Affected file silcd/silcd.c.
502 * No longer compiling lib/dotconf.
504 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
506 * Fixed JOIN command parsing not to crash. Affected file
507 lib/silcclient/command.c.
509 * Fied the NICK_CHANGE notify to add the new client entry
510 even it is resolved. This removes an <[unknown]> nick
511 thingy bug in the client. Affected file is
512 lib/silcclient/client_notify.c.
514 * Do not try to allocate 0 bytes (efence does not like it)
515 in lib/silccore/silccomand.c when encoding payload.
517 * Do not take IRCNICK as nickname in Irssi SILC client since
518 it is not possible to set nickname before hand connecting
519 the server (TODO has an entry about adding auto-nicking
522 * Changed the silc_server_command_pending to check whether
523 there already exists an pending entry with the specified
524 command, command identifier and pending callback. This is
525 to fix IDENTIFY and WHOIS related crashes that may register
526 multiple pending commands with same identifier. Affected
527 file silcd/command.c.
529 * Fixed the server to reconnect to the router even if it
530 was already reconnecting and EOF was received. This to
531 fix a possibility that the server wouldn't ever try to
532 auto-reconnect to the router. Affected file silcd/server.c.
534 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Fixed the server's password authentication to use the
537 length of the locally saved password, and not the one
538 sent in the packet. Affected file silcd/protocol.c.
540 * Fixed same password authentication problem in the
541 Authentication Payload handling routines in
542 lib/silccore/silcauth.c.
544 * Yet another password authentication problem fixed with
545 channel password handling in silcd/command.c.
547 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
549 * If first character of string in silc_parse_userfqdn is '@'
550 then do not parse it. Affected file is
551 lib/silcutil/silcutil.c.
553 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
555 * Fixed minor bug in IDENTIFY command reply sending, which
556 caused various weird problems during JOIN when it was
557 resolving names for users. Affected file silcd/command.c.
559 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Fixed the IDENTIFY command reply sending to chech better valid
562 clients. It was possible to send incomplete list of replies.
563 Affected file silcd/command.c.
565 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Added silc_client_command[s]_[un]register functions now to
568 dynamically register the commands in client library. Removed
569 the static table of commands. This allows the client library
570 to call commands without causing the application to know about
571 what commands library has called.
573 Removed the INFO command reply kludge to detect when the command
574 was called by library. Now library use its own command reply
575 function for INFO command.
577 Added function silc_client_command_call to call a command.
578 Application can use it to call command, not access the structure
581 Now all commands that are sent by the client library (not
582 explicitly sent by application) use own command reply functions.
584 Affected files around lib/silcclient/ and in
585 irssi/src/silc/core/.
587 * Fixed the WHOIS command reply sending to chech better valid
588 clients. It was possible to send incomplete list of replies.
590 Fixed the WHOIS and IDENTIFY to send the request to router
591 if normal server did not do it and did not find any results.
593 Affected file silcd/command.c.
595 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
597 * Moved the internal data from SilcClient context into its
598 own file, not accesible to application. Affected files
599 lib/silcclient/client.h and lib/silcclient/client_internal.h,
600 and other files in client library.
602 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
604 * Added doc/examples installation target in Makefile.am.pre.
607 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
609 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
610 commands the found client entry will be removed from the
611 cache, after notifying application about the error. Affected
612 file lib/silcclient/command_reply.c.
614 * Changed the /MSG to check for exact nickname user gave, and
615 not let `nick' match `nick@host' if it is only one found. Now,
616 user must type the exact nickname (like nick@host2) even if
617 there are no more than one same nicks found. This is to avoid
618 a possibility of sending nickname to wrong nickname since
619 `nick' could match `nick@host'. Affected file is
620 irssi/src/core/silc-servers.c.
622 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
624 * Do not print "you are now server operator" or similar when
625 giving /away command. Affected files are
626 irssi/src/silc/core/client_ops.c, silc-servers.h.
628 * Made the silc_server_command_pending_error_check to send
629 the same command reply payload it received back to the
630 original sender of the command. This way all arguments
631 that was received by the server will be received by the
632 client too. Affected file silcd/command.c.
634 * Added the silc_idcache_add to return the created cache entry
635 to a pointer. Affected file lib/silccore/silcidcache.[ch].
637 * Add global clients to expire if they are not on any channel.
638 This is because normal server will never know if they signoff
639 if they are not on any channel. The cache expiry will take
640 case of these entries. This is done by normal servers only.
641 The affected files are silcd/command_reply.c,
642 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
644 * If server receives invalid ID notification for WHOIS or
645 IDENTIFY and the ID exists in the lists, it is removed.
646 Affected file silcd/command_reply.c.
648 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
649 in client then client entry that it matches is searched and
650 the nickname is printed on the screen for user. Affected
651 file irssi/src/silc/core/client_ops.c.
653 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
655 * Use cache entry expire time in the LIST command reply to
656 purge old entries from the cache after the LIST command
657 reply has been received. This way we don't have non-existent
658 entries in the cache for too long. Affected file is
659 silcd/command_reply.c.
661 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
663 * If we are normal server, and we've not resolved client info
664 in WHOIS or IDENTIFY from router, and it is global client,
665 we'll check whether it is on some channel. If it is not
666 then we cannot be sure about its validity and will resolve it
667 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
668 file silcd/command.c.
670 * Search channel by name (if possible) rather than by ID
671 in IDENTIFY command's command reply. Affected file is
672 silcd/command_reply.c.
674 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
676 * Distribute to the channel passphrase in CMODE_CHANGE notify.
677 Updated specs and implemented it. Affected file silcd/command.c,
678 silcd/packet_send.c and silcd/packet_receive.c.
680 * Implemented the <founder auth> payload handling in the JOIN
681 command. If provided all conditions for channel joining
682 except requirement to provide correct passphrase can be
683 overrided by the channel founder. Updated the protocol specs.
684 Affected file silcd/command.c.
686 Added support for founder auth in JOIN command in client
687 library. Fixed the parsing of the JOIN command now to support
688 all options as they should be. The affected file is
689 lib/silcclient/command.c.
691 * Optimized the WHOIS and IDENTIFY commands to send the request
692 to router only if it includes nicknames or other names. If
693 they include only IDs then check the local cache first before
694 routing. Affected file is silcd/command.c.
696 * Added channels topic announcements. Affected file is
697 silcd/packet_receive.c and silcd/server.c.
699 * Fixed the silc_server_send_notify_topic_set to really destine
700 the packet to channel. Affected file silcd/packet_send.c.
702 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
703 library. Affected file lib/silcclient/client_notify.c.
705 * Added UMODE announcements. Affected file silcd/server.c.
707 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
709 * Memory leak fixes in:
711 lib/silcutil/silcsockconn.c
712 lib/silcske/silcske.c
715 lib/silccrypt/silcpkcs.c
716 lib/silccore/silccommand.c
717 lib/silccore/silcidcache.c
722 * ROBOdoc documented the lib/silcske/groups.h file and a
723 bit changed the interface for better.
725 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
727 * Update the client entry context in the ID cache after
728 nick change. Affected file lib/silcclient/command.c.
729 Fixes the CUMODE command when regaining founder privileges,
730 and a little WHOIS problem.
732 * Fixed silc_net_gethostbyname to correctly call the
733 inet_ntop. Affected file lib/silcutil/silcnet.c.
735 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
737 * Added IPv6 support checking to the configure.in.pre, added
738 also --enable-ipv6 option to override the check. Affected
739 file configure.in.pre.
741 * The silc_thread_create now calls the start function
742 directly if threads support is not compiled in. Removes
743 ugly #ifdef's from generic code. Affected files are
744 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
746 * Added silc_net_gethostby[name/addr]_async to asynchronously
747 resolve. Affected files are lib/silcutil/silcnet.[ch].
749 * Added support for rendering IPv6 based server, client and
750 channel IDs. Affected file lib/silcutil/silcutil.c.
752 * Added support for creating IPv6 based server IDs. Affected
753 file is silcd/serverid.c.
755 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
757 * Added silc_net_gethostby[addr/name] into the
758 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
759 routines. Added silc_net_is_ip[4/6]. Affected file is
760 lib/silcutil/unix/silcunixnet.c. All routines that take
761 address as argument now supports both IPv4 and IPv6 addresses.
763 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
765 * Fixed LIST command reply sending in server. Affected file
768 * Server now sends the kicker's client ID in the KICK notify
769 to the kicked client. Affected file silcd/command.c.
771 * The client library now parses the kickers client ID and
772 UI displays it. Affected files lib/silcclient/client_notify.c
773 and irssi/src/silc/core/silc-channels.c, module-formats.c.
775 * Made all payload parsing function prototypes consistent.
776 They all take now const unsigned char * and uint32 pair as
777 the payload data instead of SilcBuffer. Changes all around
778 the source tree. Other unsigned char* -> const unsigned char*
779 changes around the tree as well.
781 * Optimized SFTP client and server packet sending not to
782 allocate new buffer for each packet but to recycle the
783 first allocated buffer. Affected files are
784 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
786 * Optimized the SFTP client to use SilcList instead of
787 SilcDList for requests, because it is faster. Affected file
788 is lib/silcsftp/sftp_client.c.
790 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
791 into lib/silccore/silcid.[ch].
793 Renamed silcpayload.[ch] into silcargument.[ch].
795 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
797 * If client entry is deleted with active key agreement
798 session, abort the session.
800 The silc_client_abort_key_agreement now calls the completion
801 callback with new SILC_KEY_AGREEMENT_ABORTED status.
803 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
806 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
808 * Don't use __restrict in older GCC's. Affected file is
809 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
811 * silc_net_localhost now attempts to reverse lookup the
812 IP/hostname. Affected file lib/silcutil/silcnet.c.
814 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
815 command. It can be used to gain founder privileges at
816 the same time when joining the channel.
818 Defined that the SILC_NOTIFY_TYPE_KICKED send the
819 kicker's client ID as well. Updated protocol specs.
821 Defined that the server must send SILC_COMMAND_IDENTIFY
822 command reply with error status to client who sent
823 private message with invalid client ID.
825 Updated the protocol specification.
827 * Added silc_server_send_command_reply to send any
828 command reply. Affected file silcd/packet_send.[ch].
830 * Added silc_id_payload_encode_data to encode ID payload
831 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
833 * The server now send IDENTIFY command reply with error
834 status if client ID in private message is invalid. Affected
835 file silcd/packet_receive.c.
837 * Save the server key file with server's IP address in
838 the filename instead of hostname. The affected file is
839 irssi/src/silc/core/client_ops.c.
841 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
846 * Added libtool support for compiling shared objects in
847 lib/silcsim. Affected file configure.in.pre and
848 lib/silcsim/Makefile.am. Original patch by cras.
850 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
852 * Pid file configuration, and server's config file fixes
853 patch by toma. Updated CREDITS file.
855 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
857 * Fixed silc_client_channel_message to not try to decrypt
858 the message twice if it resolved the destination client
859 information. This could cause of dropping one channel
860 message. Affected file lib/silcclient/client_channel.c.
862 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
864 * Added silc_client_run_one into lib/silcclient/silcapi.h and
865 lib/silcclient/client.c. This function is used when the SILC
866 Client is run under some other scheduler, or event loop or
867 main loop. On GUI applications, for example this may be
868 desired to used to run the client under the GUI application's
869 main loop. Typically the GUI application would register an
870 idle task that calls this function multiple times in a second
871 to quickly process the SILC specific data.
873 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
875 * Fixed silc_server_drop() for dropping the supplementary
876 groups as well, this could cause a security hole on some
879 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
881 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
884 * Write PID file after dropping privileges. Added -F option
885 to run server on foreground. A patch by debolaz.
886 Affected files silcd/server.c, silcd/silcd.c.
888 * Fixed MOTD to return the MOTD file server name. Affected
889 file silcd/command.c.
891 * Added INFO command reply handling to the Irssi SILC Client.
892 Affected file irssi/src/silc/core/client_ops.c.
894 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
896 * Fixed the silc_idcache_list_* routines to really support
897 the dynamic list. Fixes a crash. Affected file is
898 lib/silccore/silcidcache.c.
900 * Fixed the LIST command reply to really call LIST command's
901 pending callbacks. Affected file silcd/command_reply.c.
903 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
905 * Update conn->local_entry->nickname after giving NICK
906 command. Affected file lib/silcclient/command.c.
908 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
910 * Added the [pid] option to the silcd configuration file
912 Affected files: serverconfig.[ch] and silcd.c
914 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
916 * Save fingerprint in WHOIS command reply in server.
917 Affected file silcd/command_reply.c.
919 * Fixed NICK commands pending callback registration.
920 Affected file lib/silcclient/command.c.
922 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
924 * Use ++server->cmd_ident when sending commands in server,
925 instead of random number. Affected file silcd/command.c.
927 * Fixed GETKEY command reply to call actually GETKEY pending
928 command callbacks. Affected file silcd/command_reply.c.
930 * A bit stricter check for nicknames. Check for same nickname
931 in NICK command also. Affected file silcd/command.c.
933 * Do not call INFO command everytime client ID changes, only
934 during first connecting. Affected file lib/silcclient/client.c.
936 * Set the new nickname only after successful command reply for
937 NICK command is returned by server. Affected file
938 lib/silcclient/command.c.
940 * Remove nicknames from nicklist during server_signoff notify.
941 Should fix /NAMES bit more. The affected file is
942 irssi/src/silc/core/silc-channels.c.
944 * Added `fingerprint' field to the SilcIDListData in the
945 silcd/idlist.h to hold the fingerprint of the client's
948 Send the fingerprint of the client's public key in WHOIS
951 Affected files silcd/command.c, and silcd/idlist.[ch].
953 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
954 create fingerprint from given data.
956 * Show the fingerprint of the client's public key in WHOIS.
957 Affected files irssi/src/module-formats.[ch] and
958 irssi/src/silc/core/client_ops.c.
960 * Format the multiple same nicknames also during JOIN and
961 NICK_CHANGE notifys. Affected file is
962 lib/silcclient/client_notify.c.
964 * Do not print error on screen for invalid private message
965 payload since it can come if someone is sending private
966 messages with wrong key. Affected file
967 lib/silccore/silcprivate.c.
969 * Fixed multiple concurrent /PING crash. Affected file
970 lib/silcclient/command.c.
972 * Changed the wrong ID encoding. All IP addresses must be
973 in MSB first order in encoded format. They were encoded
974 wrong and was in LSB format. Affected files are
975 silcd/serverid.c, lib/silcutil/silcutil.c.
977 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
979 * Call the `connect' client operation through the scheduler
980 in case of error. Affected file lib/silcclient/client.c.
982 * Call the `failure' client operation even if the error
983 occurred locally during a protocol. Affected file is
984 lib/silcclient/protocol.c.
986 * Added support of sending LIST command to router from normal
987 server. This way normal server can get list of all channels
988 in the network too. Fixed the channel list sending in the
989 server too. Affected files are silcd/command.c, and
990 silcd/command_reply.[ch].
992 * Added silc_server_update_channels_by_server and
993 silc_server_remove_channels_by_server. They are used during
994 disconnection of primary router and in backup router protocol.
995 Affected file silcd/server_util.[ch], silcd/server.c and
996 silcd/server_backup.c.
998 * Fixed channel adding to global list in IDENTIFY command
999 reply in server. Affected file silcd/command_reply.c.
1001 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * If the incoming packet type is REKEY or REKEY_DONE process
1004 that packet always synchronously. Fixes yet another MAC
1005 failed error on slow (dialup) connections. Affected file
1006 lib/silcclient/client.c and silcd/server.c.
1008 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1010 * Call check_version SKE callback for initiator too. Affected
1011 file lib/silcske/silcske.c.
1013 * Implemented fix for security hole found in the SKE that was
1014 fixed in the specification few days back; the initiator's
1015 public key is now added to the HASH value computation.
1016 Added backwards support for the old way of doing it too, for
1017 old clients and old servers. Affected file is
1018 lib/silcske/silcske.c.
1020 * Enabled mutual authentication by default in SKE. If initiator
1021 is not providing mutual authentication the responder will
1022 force it. This will provide the proof of posession of the
1023 private key for responder. The affected files are
1024 lib/silcclient/protocol.c and silcd/protocol.c.
1026 * Do not cache anymore the server's public key during SKE.
1027 We do mutual authentication so the proof of posession of
1028 private key is done, and if the server is authenticated in
1029 conn auth protocol with public key we must have the public
1030 key already. Affected file silcd/protocol.c.
1032 * Added new global debug variable: silc_debug_hexdump. If
1033 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1034 file lib/silcutil/silclog.[ch].
1036 * Fixed compilation warning due to char * -> const char *.
1037 Affected files lib/silcutil/silcnet.h, and
1038 lib/silccore/silcauth.[ch].
1040 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Fixed CMODE command when new channel key was created. If
1043 the creation failed the old key was removed. Next time giving
1044 same command would crash the server since the old key was
1045 freed already. Affected file silcd/command.c.
1047 * Fixed the silc_server_announce_get_channels to not crash
1048 on reconnect. Affected file silcd/server.c.
1050 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Added silc_log_set_debug_string function to set a regex
1053 string to match for debug output. Only the function names,
1054 or filenames matching the given debug string is actually
1055 printed. This way it is possible to filter out those debug
1056 strings that user is not interested in.
1058 Fixed a bug in silc_string_regexify.
1060 Affected files lib/silcutil/silclog.[ch], and
1061 lib/silcutil/unix/silcunixutil.c.
1063 * Changed the -d options in both server and Irssi SILC client
1064 to take the debug string as argument. Affected files
1065 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1067 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Added silc_hash_babbleprint to create a Bubble Babble
1070 Encoded fingerprint. The encoding is developed by Antti
1071 Huima (draft-huima-babble-01.txt), and it creates human
1072 readable strings out of binary data. Affected file
1073 lib/silccrypt/silchash.[ch].
1075 * Print the babble print now in addition of fingerprint as well
1076 in Irssi SILC client. Affected files are
1077 irssi/src/fe-common/silc/module-formats.[ch],
1078 irssi/src/fe-common/silc/core/client_ops.c.
1080 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1082 * Fixed a security problem found in SKE. The initiator's
1083 public key too is now added to the HASH hash value creation
1084 which is signed by the responder to create the SIGN value.
1085 This will prevent anyone in the middle to lie to the responder
1086 about the initiator's public key. If this is done now, the
1087 man in the middle will get caught. Updated the protocol
1090 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Better installation directory handling. Configure module
1093 paths and other paths automatically to example_silc* files
1094 in doc/. A patch by toma.
1096 * Fixed compiler warning from MPI library, and from SILC RNG.
1099 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1100 It can be configured with ./configure. A patch by toma.
1102 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Find correct make to use in prepare-clean. A patch by
1105 toma. Affected file prepare-clean.
1107 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1109 * Added irssi variables use_auto_addr, auto_bind_ip,
1110 auto_bind_port and auto_public_ip.
1112 * Changed the interface for silc_client_send_key_agreement
1113 in lib/silcclient/silcapi.h

1126 * Added silc_pkcs_public_key_compare to compare two
1127 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1129 * Check that the client who set the founder mode on the
1130 channel is the same client that is giving the founder
1131 mode to itself. It is done by comparing the saved public
1132 key (it is saved even in the authentication is passphrase).

1141 client library. Affected file lib/silcclient/client.c.
1143 * Fixed the silc_client_packet_parse to not to increase
1144 the packet sequence number if the conn->sock and the
1145 current socket connection is not same. This can happen
1146 for example during key agreement when the conn includes
1147 multiple socket connections (listeners). Affected file
1148 lib/silcclient/client.c.
1150 * The sender of the file transfer request now provides also
1151 the pointer (listener) for the key exchange protocol. If
1152 the listener cannot be created then it sends empty key
1153 agreement and lets the receiver provide the listener.
1155 Added `local_ip' and `local_port' arguments to the
1156 silc_client_file_send. If they are provided they are used,
1157 if not then it will attempt to find local IP address, if
1158 not found or bind fails then the remote client will provide
1161 Affected files are lib/silcclient/client_ftp.c and
1162 lib/silcclient/silcapi.h.

1171 of the client's public key (if the proof of posession of the
1172 corresponding private key is verified by the server).
1173 Updated to the protocol specification.
1175 * Added support of receiving the client's public key's
1176 fingerprint in command reply in client library. Affected
1177 file is lib/silcclient/command_reply.c, and
1178 lib/silcclient/idlist.[ch].

1237 preserve the WHOWAS info for the client. Affected file
1238 silcd/server_util.c.
1240 * Fixed SERVER_SIGNOFF notify handling in the server. The
1241 server is now able to process incoming SERVER_SIGNOFF notify
1242 for a server that it doesn't even know about. It will remove
1243 the clients provided in the notify. Affected file
1244 silcd/packet_receive.c.
1246 * Check for partial packet in data queue after every packet that
1247 was found from the queue. Return and wait for more data if
1248 there is partial data in queue. Affected file is

1266 irssi/src/fe-common/silc/module-formats.[ch].
1268 * Wrote a help file for FILE command.
1270 * Added silc_rng_global_get_byte_fast to get not-so-secure
1271 random data as fast as possible. Random data is read from
1272 /dev/urandom if available and from the SILC RNG if not
1273 available. It is used in padding generation. Affected file
1274 lib/silccrypt/silcrng.[ch].
1276 * All packets in client library are now processed synchronously.
1277 Optimized packet processing a lot. Affected file
1278 lib/silcclient/client.c.

1289 * Assure that silc_client_notify_by_server_resolve does not
1290 resolve the client information multiple times. If it cannot
1291 be found by the first it cannot be found at all. Affected
1292 file lib/silcclient/client_notify.c.
1294 * Fixed WHOWAS command reply calling. Affected file
1295 lib/silcclient/command_reply.c.
1297 * Removed all references to silc_idlist_get_client from the
1298 Irssi SILC client since that call is internal call used by
1299 the library. The Irssi SILC client will use now client
1300 retrieval functions found in silcapi.h.
1302 * Fixed a bug in resolving nickname info before sending
1303 private message. It used freed memory. Affected file
1304 irssi/src/silc/core/silc-servers.c.

1325 * Added silc_net_localip to return local host's IP address.
1326 Affected file lib/silcutil/silcnet.[ch].
1328 * If key exchange or rekey protocol is active for a connection
1329 parse all packets syncronously since there might be packets
1330 in packet queue that we are not able to process without first
1331 processing packets before them. Affected file silcd/server,
1332 lib/silcclient/client.c.
1334 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1335 whether library should continue processing the packet.
1336 Affected file lib/silccore/silcpacket.h.

1409 * Call the silc_server_udpate_servers_by_server in the
1410 primary router that comes back online in the backup resuming
1411 protocol. Otherwise it routes packets wrong. Affected file
1412 silcd/server_util.[ch], silcd/server_backup.c.
1414 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1417 lib/silcutil/silcbuffmt.[ch].

1420 length. Affected file lib/silccore/silcpacket.[ch].
1422 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1423 length for maximum padding up to 128 bytes). Affected
1424 file lib/silccore/silcpacket.h.
1426 * Removed all backwards support for old 0.5.x MAC thingies.
1427 The SILC packet header change makes it impossible to be
1428 backwards compatible.
1430 * Send the ENDING packet with timeout in the backup resuming
1431 protocol. This is to assure that all routers has connected
1432 to the primary router. Affected file silcd/server_backup.c.
1434 * Changed the RNG to take the first IV from random data. It
1435 used to take it from zero actually. Changed the RNG also
1436 to use /dev/urandom during session. /dev/random is used
1437 in initialization. Affected file lib/silccrypt/silcrng.[ch].

1442 (the packet length) encrypted. Affected files aroung the
1443 code tree, lib/silccore/silcpacket.[ch]. Removed the
1444 SilcPacketCheckDecrypt callback. It is not needed anymore
1445 since the silc_packet_receive_process will determine now
1446 whether the packet is normal or special.

1457 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Allow backup router to announce servers. All servers
1460 announced by backup router are added to the global list
1461 automatically. Update hte server's socket to our primary
1462 router also when backup router announces a server.
1463 Affected file silcd/packet_receive.c.
1465 * Do not update the client->router in the function
1466 silc_server_udpate_clients_by_server if the client is on
1467 global list. We might fail to find any specific server
1468 for locally connected clients and local cell clients. They
1469 should still use the `from' and not `to' as client->router.
1470 This fixes backup router resuming protocol. Affected file
1471 silcd/server_util.c.
1473 * Decrease channel statistics count only if the channel
1474 deletion worked. Affected files are silcd/server.c and
1475 silcd/server_util.c.
1477 * Added silc_server_update_servers_by_server to update origin
1478 of all server entries. Used during backup router protocol.

1495 to the router it came from. Affected file is
1496 silcd/packet_send.c. Fixed memory leak too.
1498 * Announce informations for incoming router connection, but
1499 only after checking if it is replaced by backup router.
1500 Affected file silcd/packet_receive.c.
1502 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1505 router environment. Affected file silcd/server_backup.c.
1507 * Route packet only to one router in the function
1508 silc_server_packet_send_to_channel. Affected file is
1509 silcd/packet_send.c.
1511 * Fixed silc_server_send_notify_dest to set the broadcast
1512 flag. Fixed the silc_server_send_notify_topic to actually
1513 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1514 Affected file silcd/packet_send.c.
1516 * Changed the SFTP Filesystem interface. Changed the
1517 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1518 the filesystem operation function. The SilcSFTPFilesystem
1519 is now a context that is allocated by all filesystem allocation
1520 functions and it already includes the operations structure
1521 and filesystem specific context. It is given as argument
1522 now to the silc_sftp_server_start. This made the interface
1523 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1524 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1526 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Changed the backup router adding and getting interfaces
1529 in the server. The router that will be replaced by the

1591 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1592 in the server to indicate disabled entry. All data read
1593 from the connection will be ignored and no data is sent
1594 for entry that is disabled. Affected files are
1595 silcd/idlist.h, silcd/server.c.

1636 to includes/bitmove.h.
1638 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Fixed channel user mode saving in client library. Affected
1641 file lib/silcclient/command[_reply].c.
1643 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1645 * Defined the file transfer to the SILC Protocol. Added
1646 new packet type SILC_PACKET_FTP and defined File Transfer
1647 Payload. The mandatory file transfer protocol is SFTP
1648 (SSH File Transfer Protocol). Affected file in addition
1649 of the internet draft is lib/silccore/silcpacket.h.
1651 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1652 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1653 is used as part of backup router protocol when the primary
1654 router of the cell is back online and wishes to resume
1655 the position as primary router.
1657 * Redefined the MAC generation keys in the protocol. The
1658 same key is not used anymore in both direction. Both
1659 direction will now use different keys for sending and
1660 receiving. This fixes a potential security flaw. This
1661 change causes incompatibilities in the protocol.
1663 * Redefined also the MAC computation from the packet.
1664 An packet sequence number is now added to the MAC
1665 computation. This prevents possible replay attacks against
1666 the protocol. This change too causes incompatibilities
1669 Added `sequence' field to the SilcPacketContext to hold
1670 the current sequence number for the packet.
1672 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1674 * Added `created' field to the SilcIDListData in the file
1675 silcd/idlist.h to indicate the time when the entry was
1678 * Added `created' field to the SilcChannelEntry too. Affected
1679 file silcd/idlist.h.
1681 * Added `creation_time' aguments to all the announcement functions
1682 in the server. If it is provided then only the entries that
1683 was created after the provided time frame are actually
1684 announced. Affected file silcd/server.[ch].
1686 * The protocol says that the Channel ID's IP address must be
1687 based on the router's IP address. Added check for this in
1688 the silc_server_new_channel when processing incoming New Channel
1689 Payload. Affected file silcd/packet_receive.c.
1691 * Print out the correct version with --version in SILC client.
1692 Affected file irssi/src/silc/core/silc-core.c.
1694 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Fixed WHOWAS command to check for completnes of the client
1697 entry always, not just when the command is coming from client.
1698 Affected file silcd/command.c.
1700 * Added new function silc_server_packet_queue_purge to purge the
1701 outgoing data queue to the network. After the function returns
1702 it is guaranteed that the outgoing packet queue is empty.
1703 Affected file silcd/packet_send.[ch].
1705 * Purge the outgoing packet queue in the rekey protocol's final
1706 callback to assure that all rekey packets go to the network
1707 before quitting the protocol. Affected file silcd/server.c.
1709 * Added silc_client_packet_queue_parse as similar function as
1710 in server to the client library. The affected file is
1711 lib/silcclient/client.c.
1713 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Splitted silcd/server.c and created silcd/server_util.[ch]
1716 for utility functions.
1718 * Added new socket flag SILC_SF_DISABLED to indicate that the
1719 connection is open but nothing can be sent to or received from
1720 the connection. Affected file lib/silcutil/silsockconn.[ch].
1721 The checking for disabled socket is checked in the low level
1722 silc_socket_write and silc_socket_read functions.
1724 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1726 * Allow only nicknames and channel names that fits into the
1727 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1729 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * When processing JOIN command reply in server check that if
1732 the channel exists in our global list we'll move it the local
1733 list. Affected file silcd/command_reply.c.
1735 * Fixed the check whether client is joined on the channel already
1736 in JOIN command. Affected file lib/silcclient/command.c.
1738 * Fixed the JOIN command reply to check whether the channel
1739 already exists. Affected file lib/silcclient/command_reply.c.
1741 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1743 * Added silc_ske_status_string to map the SKE error numbers
1744 to readable strings. The affected files are
1745 lib/silcske/silcske[_status].[ch].
1747 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Do not show the private channels on the WHOIS channel list
1750 as it is not allowed by the protocol. The affected file is
1753 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Assure that the packet length digged from the actual packet
1756 is something sensible in the silc_packet_decrypt_rest_special
1757 in lib/silccrypt/silcpacket.c.
1759 * Free and NULL the allocated pointer in silc_hmac_alloc if
1760 the HMAC allocation fails. The affected file is
1761 lib/silccrypt/silchmac.c.
1763 * Print the selected security properties to the log files in
1764 the server. Affected file silcd/protocol.c.
1766 * Add SKE's reference counter even if calling the completion
1767 callback manually. Otherwise it goes negative, although it
1768 does not cause any problems. The affected file is
1769 lib/silcske/silcske.c.
1771 * Remove the client entry with short timeout after giving the
1772 KILL command. Affected file lib/silcclient/command.c.
1774 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1775 case all found clients are already disconnected (WHOWAS would
1776 found them) in the server. Affected file silcd/command.c.
1778 * Update the last_receive (time of last data received) to be
1779 updated only when received private or channel message so that
1780 the idle time showed in WHOIS makes more sense.
1782 * Added boolean field `valid' in to the SilcClientEntry in the
1783 client library to indicate whether the entry is valid or not.
1784 This fixes the nickname change bug on channel when changing
1785 the nickname to be same than the old (like nick to Nick) the
1786 nickname formatter doesn't set the new nick anymore to Nick@host.
1787 Affected file lib/silcclient/idlist.[ch].
1789 * Now actually fixed the nickname changing on disconnection.
1790 Added new function silc_change_nick to the Irssi SILC Client.
1791 Affected file irssi/src/silc/core/client_ops.c,
1792 irssi/src/silc/core/silc-nicklist.[ch].
1794 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Check that the public key exists in the GETKEY command before
1797 trying to encode it. Affected file silcd/command.c.
1799 * Print some notifications on received public keys with GETKEY
1800 command in the Irssi SILC Client. Affected files are
1801 irssi/src/fe-common/silc/module-formats.[ch],
1802 irssi/src/silc/core/client_ops.c.
1804 * Use IDENTIFY command to resolve the server information in the
1805 GETKEY command instead of INFO command. Affected file
1806 lib/silcclient/command.c.
1808 * All command reply functions in the client library now calls
1809 the pending command reply callbacks even if an error has
1810 occurred. The server has done this a long time and now it was
1811 time to move the client library to this as well. Now all
1812 errors can be delivered back to the pending command reply
1813 callbacks if necessary. Affected files are
1814 lib/silcclient/command[_reply].[ch].
1816 * Change the nickname on disconnection back to the username
1817 because in reconnect the server will enforce it to it anyway.
1818 Affected file irssi/src/silc/core/silc-servers.c.
1820 * Fixed a config file parsing bug in the Irssi SILC client.
1821 Affected file irssi/src/silc/core/clientconfig.c.
1823 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * When printing the channel mode on JOIN, verify that the
1826 channel key and channel's HMAC are valid. Affected file
1827 irssi/src/silc/core/client_ops.c.
1829 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1832 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1833 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1835 * Removed channel key rekey task deleting from the function
1836 silc_server_save_channel_key. Affected file silcd/server.c.
1837 Added explicit timeout task context instead that is used to
1838 delete the task if we are registering a new task before the
1839 new task has elapsed.
1841 * When channel key rekey occurs the client library now saves
1842 the old channel key for a short period of time (10 seconds) and
1843 is able to use it in case some is still sending channel
1844 messages encrypted with the old key after the rekey. Affected
1845 file lib/silcclient/[idlist.h|client_channel.c].
1847 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Added check to the silc_server_new_id_real to not accept
1850 new ID if it is the sender's own ID. Affected file is
1851 silcd/packet_receive.c.
1853 * Assure that we do not announce ourself or the one we've
1854 sending our announcements when we're router and are announcing
1855 servers to our primary router. Affected file silcd/server.c.
1857 * Fixed silc_server_command_identify_check_client to assemble
1858 correct WHOIS packet. It send corrupted WHOIS packet and
1859 caused problem with router to router connections. Affected
1860 file silcd/command.c.
1862 Fixed also silc_server_command_whois_check the same way
1863 as for the IDENTIFY command.
1865 * Added new SilcIDListStatus to the server in the SilcIDListData
1866 structure. The status now includes the current status of
1867 the entry (like registered, resolved etc.). Affected file
1868 silcd/idlist.[ch]. Defined a bunch of different status types
1869 as well. This replaced the old boolean registered field as well.
1871 Added resolve_cmd_ident field to the SilcClientEntry structure
1872 too so that if the entry is for example being resolved so
1873 another command may attach to the same pending command reply
1874 without requiring to resolve the same entry again. This concept
1875 should optimize the WHOIS and the IDENTIFY resolving under
1876 heavy load by taking away unnecessary resolving for entries
1877 that are being resolved already.
1879 Added support for adding multiple pending commands for one
1880 command idenfier. Affected file silcd/command[_reply].[ch].
1882 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1883 before deleting the data. Otherwise the hash table will have
1884 freed data in comparison functions. Affected file is
1885 silcd/command_reply.c.
1887 * Fixed silc_idlist_replace_client_id to add the new entry to
1888 the cache with NULL nickname. Otherwise there will be invalid
1889 memory as the nickname after the nickname is freed. Affected
1890 file silcd/packet_receive.c.
1892 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1893 saved into wrong slots because the previous number of entries
1894 was not taken into account. Affected file silcd/idlist.c.
1895 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1897 * If we are router and we receive JOIN notify to a channel that
1898 does not have any users then notified client is marked as the
1899 channel founder, as it is it. The affected file is
1900 silcd/packet_receive.c
1902 * Added to the extended hash table API's table_del_*ext functions
1903 the destructor as argument too, so that the caller can decide
1904 which destructor to use or whether to use destructor at all.
1905 Affected file lib/silcutil/silchashtable.[ch].
1907 * Fixed ID Cache purging. It actually deleted the entries from
1908 the hash table after the data was freed. The hash table ended
1909 up comparing freed memory. The affected file is
1910 lib/silccore/silcidcache.c.
1912 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Fixed Irssi SILC client's KILL command's HELP syntax.
1916 * The USERS command now resolves the detailed user information
1917 if the userinfo field is missing. Affected file is
1918 lib/silcclient/command_reply.c.
1920 * Do not print error in silc_file_read if the read file does
1921 not exist. Just silently return NULL. Affected file is
1922 lib/silcutil/silcutil.c.
1924 * Fixed the silc_log_output to not wine about NULL filename
1925 and to not create some bogus " " filename. Affected file is
1926 lib/silcutil/silclog.c.
1928 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1930 * Fixed various printing bugs on the user interface in the
1931 Irssi SILC Client. Minor changes that were forgotten from
1934 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Fixed the configure.in.pre and the compilation and distribution
1937 environment to support the new autoconf 2.52. That version is
1938 now required to compile the CVS trunk.
1940 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1943 to generally parse user@fqdn format strings. Affected file
1944 lib/silcutil/silcutil.c.
1946 * Added nickname_format and nickname_force_format fields to the
1947 SilcClientParams structure. The first one defines the format
1948 for the nicknames that the library will enforce if the receives
1949 multiple same nicknames. The second one is boolean value and
1950 can be used to force the library to always enforce the format
1951 to the nicknames regardles whether there are multiple nicknames
1952 or not. This configurable formatting was employed to flexibly
1953 support accessing multiple nicknames from the user interface.
1954 The userinterface can now set the nicknames to what ever format
1955 they prefer. Affected file lib/silcclient/silcapi.h.
1957 Added function silc_client_nickname_format to the file
1958 lib/silcclient/idlist.c. It performs the nickname formatting.
1960 Added new field `hostname´ to the SilcClientEntry context.
1961 It holds the hostname of the client. Affected file is
1962 lib/silcclient/idlist.h.
1964 * Irssi SILC Client sets the nicknames in nick@hostn format.
1965 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1966 irssi/src/silc/core/silc-core.c.
1968 The WHOIS printing now also shows both the real nickname and
1969 the formatted nickname so that user knows how to access the
1970 user if there are multiple same nicknames cached. Affected
1971 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1972 printing formatting too to take the hostname now as a separate
1973 argument. The Affected file is
1974 irssi/src/fe-common/silc/modules-formats.[ch].
1976 * Changed the silc_client_get_clients_local to accept the formatted
1977 nickname as argument. It accepts the real nickname too but the
1978 formatted nickname can be used to find the true entry from
1979 multiple entries. Affected file lib/silcclient/silcapi.h and
1980 lib/silcclient/idlist.c.
1982 * Added nickname_format_parse field to the SilcClientParams.
1983 It is a callback function provided by the application to parse
1984 the nickname out of the formatted nickname string. The library
1985 calls it to get the nickname from the formatted string. Since
1986 the application generally knows better the format of the nickname
1987 string it parses it instead of the library, even though library
1988 encodes the formatted string. If the callback function is not
1989 provided then the library will use the string as is. The
1990 affected file is lib/silcclient/silcapi.h.
1992 * All the nickname strings passed to the client library in
1993 commands are now expected to be formatted nickname strings.
1994 If the command does not support the formatted nickname string
1995 it will assume that the sent string is the actual nickname.
1996 Affected file lib/silcclient/command.c.
1998 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Added public key authentication support to OPER and SILCOPER
2001 commands in the client library. Affected file is
2002 lib/silcclient/command.c.
2004 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * Changed the get_auth_methdod client operation to be asynchronous.
2007 It can be async if the application resolves the authentication
2008 method from the server during the negotiation. Added new
2009 SilcGetAuthMeth completion callback that the application will
2010 call after resolving the authentication method.
2012 Added function silc_client_request_authentication_method that
2013 the application can use to resolve the authentication method
2014 from the server. Added also SilcConnectionAuthRequest callback
2015 that the library will call after the server has replied. The
2016 application can call this function if it does not know the
2017 current authentication method.
2019 Affected files are lib/silcclient/client.c and
2020 lib/silcclient/silcapi.h.
2022 * The Irssi SILC client now automatically resolves the authentication
2023 method incase any configuration information is not present (and
2024 currently there never is). The affected file is
2025 irssi/src/silc/core/client_ops.c.
2027 * Fixed public key authentication from the client library.
2028 Affected file lib/silcclient/protocol.c. Changed also the
2029 protocol specification about the public key authentication in
2030 the connection authentication protocol. The actual data to be
2031 signed is now computed with a hash function before signing.
2033 * Fixed the public key authentication from the server as well.
2034 Affected file silcd/protocol.c.
2036 * Removed the mlock()'s from the memory allocation routines.
2037 Affected file lib/silcutil/silcmemory.c. The ./configure does
2038 not check anymore for the mlock(). Affected file is
2041 * Fixed USERS command in server to allow the execution of the
2042 command for private and secret channels if the client sending
2043 the command is on the channel. Affected file silcd/command.c.
2045 * Fixed silc_client_get_clients_local to return the clients
2046 count correctly. It could return wrong value. Affected file
2047 lib/silcclient/idlist.c.
2049 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2052 types. The assembler optimizations seemed not to like 64-bit
2053 data types. The assmebler optimizations thus are now enabled
2054 also for BSD systems as opposed to only enable them for Linux.
2056 * Do not check for threads at all on BSD systems. Affected
2057 file configure.in.pre.
2059 * Removed -n and -h options from the Irssi SILC Client since
2060 they are not used in silc.
2062 * Fixed the prime generation to assure that the first digit
2063 of the generated random number is not zero since our conversion
2064 routines does not like number strings that starts with zero
2065 digit. If zero digit is seen the random number is regenerated.
2066 This caused some corrupted RSA keys when the zero first digit
2067 was met. Affected file lib/silcmath/silcprimegen.c.
2069 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * Fixed WIN32 configuration in the ./configure script.
2072 Fixed to include xti.h on environments that has it.
2073 Patches by Carsten Ilchmann and andrew.
2075 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Changed the silc_id_create_client_id to be collision
2078 resistant. It is now assured that there cannot be created
2079 two same client ID's. I suspect that some weird bugs in
2080 the server were actually caused by duplicate Client IDs.
2081 Affected file silcd/serverid.[ch]. A router receiving
2082 new ID now also assures and informs the sending server
2083 if the ID caused collision.
2085 * Changed the silc_id_create_channel_id to also assure that
2086 there are no collisions.
2088 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Statement about ignoring the Mutual Authentication flag when
2091 performing rekey with PFS was a bit misleading. It is ignored
2092 if it was set in the initial negotiation, it cannot be even
2093 set in the rekey. Fixed in the ke-auth draft. Started the
2094 new versions of the protocol drafts in the doc/.
2096 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Fixed a bug in silc_client_command_identify_save when saving
2099 new channel information. The channel name was no duplicated
2100 and caused crash on exit. Affected file is
2101 lib/silcclient/command_reply.c.
2103 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Fixed the getkey command handling in the server. Send just
2106 empty OK reply to the sender if the key could not be fetched
2107 (but everything else was ok, like the key just was not available).
2108 Changed the public key parameter to optional in the protocol
2109 specs so that empty OK reply can be sent. Affected file
2112 Added a message to Irssi SILC client to tell to user if the
2113 server did not return a public key.
2115 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Fixed a channel key regeneration bug. It registered new
2118 timeout tasks exponentially until all system resources were
2119 used. Affected file silcd/server.c.
2121 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Added the SILC Document generator to the scripts/silcdoc.
2124 It can be used to generate the Toolkit Reference Manual out
2125 of the source tree. Internally it will also use the RoboDoc
2126 generator now imported in util/robodoc.
2128 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Added couple of return's in rekey protocol if error orccurred
2131 during the protocol. The execution must be terminated.
2132 Affected file silcd/protocol.c. Also, terminate the protocol
2133 always with timeout.
2135 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * The client's Client ID was created initally from the wrong
2138 nickname (it could have been in format nick@host) in the
2139 silc_server_new_client. Affected file silcd/packet_receive.c
2141 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Added some SILC_LOG_ERROR's to various error conditions
2144 if client could not be added to ID cache. Affected files
2145 silcd/packet_receive.c and silcd/server.c.
2147 * When client's sock->user_data is freed, NULL also the
2148 client->router and client->connection pointers. Added check
2149 for these pointers being NULL to various places around the
2150 code. Affected file silcd/server.c.
2152 * Added client->data.registered == TRUE checks to various
2153 places around the code to assure that unregistered client's
2154 are not handled when it is not allowed. Affected file
2157 * Added `bool registered' fields to all
2158 silc_idlist_[server|client]_get_* routines to indicate whether
2159 the fetched client needs to be registered or not. Affected
2160 file silcd/idlist.[ch].
2162 * Add your own entry as registered to the ID cache in the
2163 server. Affected file server.c.
2165 * Fixed a bug in silc_server_new_server. The SilcServer was
2166 set as the new server's context instead of SilcServerEntry.
2167 This naturally caused some weird bugs.
2169 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Do not delete the channel rekey task when adding it
2172 for in silc_server_create_channel_key.
2174 * Changed the silc_server_create_channel_key to return
2175 TRUE or FALSE to indicate the success of the channel key
2178 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Fixed MSVC++ project files and added missing files to

2186 does not have it defined. Affected files are
2187 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2189 * Fixed buffer overflow from Irssi SILC Client. Affected
2190 file irssi/src/fe-common/core/themes.c.
2192 * Fixed double free in client library in the file
2193 lib/silcclient/client.c when disconnecting from server.
2195 * Applied double free patch from cras to Irssi SILC client.
2196 Affected files irssi/src/core/[modules/expandos].c
2198 * Fixed the disconnection handling to Irssi SILC Client.
2199 The application must call silc_client_close_connection
2200 in ops->connect client operation in case of failure of
2201 the connection. Affected file is
2202 irssi/src/silc/core/client_ops.c.
2204 * Do not set sock->protocol to NULL in the function
2205 silc_client_close_connection after executing the protocol's
2206 final callback since the sock might not be valid anymore.
2207 Affected file lib/silcclient/client.c.
2209 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2211 * Do not enable SILC_THREADS if the linking with libpthread
2212 did not happen. Affected file configure.in.pre.
2214 * Added notion to protocol specification that server must
2215 verify the sent authentication payload with CMODE when
2216 setting the channel founder key. Implemented it to the
2217 server. Affected file silcd/command.c.
2219 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Added _EXTRA_DIST SILC distribution variable to the
2222 distributions file. It is used to conditionally add extra
2223 files or directories to the specific distribution. Affected
2224 files ./prepare, Makefile.am.pre and distributions.
2226 Removed the `_' from the start of the distribution names.
2229 * Added README.WIN32 for instructions to compile the Toolkit
2232 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Fixed a double free in disconnection in the server. Affected
2235 file is silcd/server.c.
2237 * Fixed the lib/silcske/groups.c to work now also with GMP
2238 MP library. The string conversion did not work when using
2239 specific base and the base is indicated in the string as well.
2241 * Created win32/ directory which now includes MSVC++ specific
2242 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2243 It will appear only in the toolkit distribution
2245 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2247 * Changed the key material distribution function in case when
2248 the hash output is too short. The data is now concatenated
2249 a bit differently than it used to. Made the change to the
2250 SKE protocol specification.
2252 * Added better GMP detection to configure.in.pre. A patch
2255 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Fixed a minor bug in SKE that might cause some problem on
2258 some platforms. Affected file lib/silcske/silcske.c.
2260 * Added the cookie checking for initiator in the SKE. It checks
2261 that the responder returns the sent cookie unmodified. The
2262 affected file is lib/silcske/silcske.c. Added new SKE
2263 error type INVALID_COOKIE that can be sent during the
2264 negotiation. Fixed some memory leaks as well.
2266 * Added the "invalid cookie" error message to Irssi SILC client's
2269 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2271 * Added `task_max' field to the SilcClientParams to indicate
2272 the maximum tasks the scheduler can handle. If set to zero,
2273 default values are used. Affected file lib/silcclient/silcapi.h.
2275 * Fixed memory leaks in silc_client_close_connection. Affected
2276 file lib/silcclient/client.c.
2278 * Added silc_client_del_client_entry to client library to free
2279 all memory of given client entry. Affected file is
2280 lib/silcclient/idlist.[ch].
2282 * Added new functions silc_client_del_channel and
2283 silc_client_del_server to delete channel and server entries.
2284 Affected file lib/silcclient/[silcapi.h/idlist.c].
2286 * Removed silc_client_del_client_by_id from silcapi.h.
2288 * Fixed the INFO command to return the server's own info
2289 correctly when querying by Server ID. Affected file is
2292 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Removed the non-blocking settings in WIN32 code in the
2295 silc_sock_[read/write] and added SleepEx instead. Affected
2296 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2297 of input data is now checked with FIONREAD and ioctlsocket.
2299 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Call silc_schedule_task_del_by_context in the
2302 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2303 Affected file lib/silccore/silcprotocol.c.
2305 * Call silc_protocol_cancel for active protocols in the
2306 silc_server_close_connection if the funtion
2307 silc_server_free_sock_user_data has not been called.
2308 Affected file silcd/server.c.
2310 * Generic tasks cannot be deleted using the del_by_fd
2311 task deleting function since generic tasks does not match
2312 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2314 * Added a notion to SILCOPER help file that the SILCOPER works
2315 only on router server, not on normal server.
2317 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2319 * Added for WIN32 support for the new scheduler as well.
2320 Affected file lib/silcutil/win32/silcwin32schedule.c.
2322 * Fixed the SHA1 implementation to work on various platforms.
2324 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2327 API. It is part of the scheduler now. Everything else is
2328 as previously but some functions has changed their names.
2329 Checkout the lib/silcutil/silcschedule.h for the interface.
2330 Updated all applications to use the new interface. Affected
2331 files are lib/silcutil/silcschedule.[ch].
2333 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Found a bug in the SKE implementation. The HASH value,
2336 specified by the protocol, was not computed correctly. The
2337 public key of the responder was not added to the computation
2338 even though it is mandatory. Affected file lib/silcske/silcske.c.
2339 This unfortunately causes incompatibilities with older
2340 clients and servers.
2342 * Added WIN32 specific network init and uninit functions:
2343 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2344 the Winsock2. Affected file lib/silcutil/silcnet.h and
2345 lib/silcutil/win32/silcwin32net.c.
2347 * Set the socket always to nonblocking mode on WIN32 after
2348 reading data or writing data. Affected file is
2349 lib/silcutil/win32/silcwin32sockconn.c.
2351 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Fixed various compilation problems under WIN32. Affected
2354 files lib/silcutil/win32/silcwin32thread.c and
2355 lib/silcutil/win32/silcwin32schedule.c.
2357 * Removed all _internal.h #includes from public header
2358 files. Internal headers must never be included from
2361 Removed also the lib/silcske/payload_internal.h file.
2363 * All include files that may be needed (public and some others
2364 included by the public headers) by application developers are
2365 now copied to the ./includes directory. It does not copy any
2366 internal headers. Affected file Makefile.defines.pre and all
2367 Makefile.am's under lib/ and subdirs.
2369 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Do not change the ~/.silc directory's permissions automatically.
2372 Affected file irssi/src/silc/core/clientutil.c.
2374 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Do not cancel the protocol in silc_server_close_connection
2377 it might cause recursion. Now cancelled in the function
2378 silc_server_free_sock_user_data. Affected file silcd/server.c.
2380 * Fixed the silc_server_remove_clients_by_server to regenerate
2381 the channel keys correctly finally. Added also new function
2382 silc_server_remove_clients_channels to actually do it.
2383 Affected file silcd/server.c.
2385 * Fixed the silc_server_new_channel to not crash by giving
2386 wrong router to the new channel. Affected file is
2387 silcd/packet_receive.c.
2389 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2392 which is given as argument to the silc_client_alloc now.
2393 It can be used to configure the client and set various parameters
2394 that affect the function of the client.
2396 * The USERS command in server did not check whether the channel
2397 is private or secret. Affected file silcd/command.c.
2399 * Added new argument to the USERS command in protocol specification.
2400 The USERS command now can take the channel name as argument
2401 as well. Added support for this in client and server and
2402 updated the protocol specs.
2404 * Completed the GETKEY command in client. It can be now used
2405 to fetch also servers public key not only some clients.
2406 Affected files lib/silcclient/command[_reply].c.
2408 * Added silc_client_get_server to return server entry by the
2409 server name. Affected files lib/silcclient/silcapi.h and
2412 * Redefined the IDENTIFY command in protocol specification to be
2413 more generic. It now can be used to query information about
2414 any entity in the SILC Network, including clients, servers and
2415 channels. The query may be based either the entity's name
2416 or the ID. Added support for this in both client and server.
2418 Affected files silcd/command.c and lib/silcclient/command.c
2419 and command_reply.c.
2421 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2422 the _from_client and _from_server functions. Affected file
2425 * Added silc_client_get_channel_by_id_resolve to the file
2426 lib/silcclient/silcapi.h to resolve channel information by
2427 its ID. Added also silc_client_get_channel_by_id that
2428 does not resolve it from the server.
2430 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Added SilcServerEntry context into the client library
2433 to represent one server. The INFO command now allocates
2434 these to save the resolved server info. For now on the
2435 client library will also keep information about servers,
2436 connected and resolved with INFO.
2438 The INFO command now allocates the SilcServerEntry context
2439 and saves the server info there. The COMMAND_REPLY in
2440 the INFO now returns the parameters to application in
2441 same order as defined in the protocol specification.
2443 The entries are cached in the client->server_cache.
2445 * The INFO command is now issued after received the Client ID
2446 from the server. Affected file lib/silcclient/client.c.
2448 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2449 to the application as the mode changer might be server.
2450 It is guaranteed that NULL is not returned anymore to the
2451 application. Affected file lib/silcclient/client_notify.c.
2453 The ID Type is now also passed to the application so that
2454 it can check whether the returned entry is SilcClientEntry
2457 Added new function silc_client_get_server_by_id to return
2458 the server entry by ID. Affected files are the
2459 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2461 * Do not create the channel in the Irssi SILC Client when issuing
2462 the JOIN command but when received the sucessful JOIN command
2463 reply. Otherwise the channel might get created even though we
2464 could not join it. The Affected file is
2465 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2467 * Fixed a channel joining bug in router. The router must also
2468 check the channel modes, invite and ban lists etc. when serving
2469 the JOIN command sent by normal server. Affected file is
2470 silcd/command.c. The router now resolves the client's
2471 information from the server who sent the JOIN command if it
2472 does not know it, and processes the JOIN command only after
2475 * Changed the SilcCommandCb to take new argument; void *context2.
2476 Affected file lib/silccore/silccommand.h
2478 The second argument in the command callbacks in the server now
2479 includes the SilcServerCommandReplyContext if the command was
2480 called as pending command callback from the command reply.
2481 Otherwise it is NULL. When called as pending the status of the
2482 command reply will be checked and if it was erronous the
2483 error will be sent to the original sender of the command.
2484 This way the client always receives the error messages even
2485 though the server was actually the one who received the error
2486 when it resent the command to router, for example. Affected
2487 files silcd/command[_reply].[ch].
2489 * Fixed sending WHOWAS command's error message to client if
2490 the requested client could not be found. It was missing.
2493 * Changed the CMODE and CUMODE commands reply arguments in the
2494 protocol specification. The Channel ID is now sent in both
2495 of the commands to identify the channel. Implemented this
2496 new feature to the client and server. Affected files
2497 lib/silcclient/command_reply.c and silcd/command.c.
2499 * Made better checks for invite and ban lists in the JOIN
2500 command in server. Affected file silcd/command.c.
2502 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * The server now performs the incoming host IP/DNS lookup
2505 using the silc_socket_host_lookup and thus does not block
2506 the server anymore. Affected file silcd/server.c.
2508 * Completed the multi-thread support for SILC Scheduler in
2509 the lib/silcutil/silcschedule.c.
2511 * Fixed the configure.in.pre to detect the pthread correctly
2514 * Fixed a deadlock in silc_task_queue_wakeup in the file
2515 lib/silcutil/silctask.c.
2517 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Added new function silc_schedule_wakeup that is used in
2520 multi-threaded environment to wakeup the main thread's
2521 schduler. It needs to be used when a thread adds a new task
2522 or removes a task from task queues. After waking up, the
2523 scheduler will detect the task queue changes. If threads
2524 support is not compiled in this function has no effect.
2525 Implemented the wakeup mechanism to both Unix and WIN32
2526 systems. Affected files are lib/silcutil/silcschedule.[ch],
2527 lib/silcutil/unix/silcunixschedule.c and the
2528 lib/silcutil/win32/silcwin32schedule.c.
2530 * Added new function silc_task_queue_wakeup to wakeup the
2531 scheduler by the specified task queue. Affected file
2532 lib/silcutil/silctask.[ch].
2534 * The silc_socket_host_lookup_start now wakes up the scheduler
2535 after adding the timeout task. Affected file is
2536 lib/silcutil/silcsockconn.c.
2538 * The silc_socket_host_lookup is synchronous now if the threads
2539 support is not compiled in. However, the callback is still
2540 called asyncronously through the scheduler, anyway. Affected
2541 file lib/silcutil/silcsockconn.c.
2543 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Added new function silc_socket_host_lookup to perform
2546 asynchronous IP and FQDN lookups for the socket connection.
2547 Affected files lib/silcutil/silcsockconn.[ch].
2549 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2551 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2552 that may or may not compile the mutex support in.
2554 Changed the silc_mutex_alloc interface. It allocates the
2555 mutex now to the sent pointer and returns TRUE or FALSE.
2557 Affected file lib/silcutil/silcmutex.h.
2559 * Wrote the SILC Task Queue interface to support multi-threads.
2560 Affected file lib/silcutil/silctask.[ch].
2562 * Wrote the SILC Scheduler to support multi-threads. Affected
2563 file lib/silcutil/silcschedule.c.
2565 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2568 in lib/silcutil/win32/.
2570 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Defined SILC Mutex API and SILC Thread API and implemented
2573 them for Unix. Affected files are
2574 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2575 lib/silcutil/unix/silcunixmutex.c and
2576 lib/silcutil/unix/silcunixthread.c.
2578 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Fixed the silc_server_remove_clients_by_server's channel
2581 key re-generation. The hash table handling was incorrect
2582 and would not work with many channels. Affected file is
2585 * Fixed some memory leaks around the server code.
2587 * Rewrote the silc_server_get_users_on_channel to support IPv6
2588 based Client ID's. Affected file silcd/server.c.
2590 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2591 specification. However, a separate document must be written
2592 to define the detailed signing procedure and the payload
2593 associated with the flag. Defined the flag to the
2594 lib/silccore/silcchannel.h as well.
2596 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Changed the dynamic tables to static size tables in the
2599 lib/silccrypt/silchmac.c.
2601 * Removed GCC dependencies from the code. A patch by cras.
2603 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Do not show the error "Error receiving packet bla bla"
2606 in server if it really was not an error (-2 means that reading
2607 is pending). Affected file silcd/server.c.
2609 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Fixed a possible crash in silc_server_remove_clients_by_server
2612 in silcd/server.c. Fixed there also some memory leaks.
2614 * Fixed the silc_idlist_replace_client_id. It could replace
2615 wrong key in the hash table. Affected file silcd/idlist.c.
2617 * Do not check whether there are global users on the channel
2618 if the channel->global_users is FALSE. Affected functions
2619 silc_server_remove_from_one_channel and
2620 silc_server_remove_from_channels in silcd/server.c. Also,
2621 do not check if the removed client is local as we can be
2622 sure that global client was not removed from the channel
2623 and checking for global users is not needed.
2625 * The silc_server_remove_clients_by_server now re-generates
2626 the channel keys correctly for those channels that had
2627 clients removed from them. Affected file silcd/server.c.
2629 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2631 * Found the reason of random crashes in the server. We weren't
2632 ignoring the SIGPIPE signal (which can be sent in write())
2633 and it crashed the server. Affected file silcd/silcd.c.
2635 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Assure that sock->user_data is not NULL in the function
2638 silc_server_packet_send in silcd/packet_send.c.
2640 * Disconnect the remote connection if it could not be added
2641 to any ID lists in the server. The affected file is
2644 * Check in silc_server_packet_send[_real/dest] that the
2645 socket is not disconnecting and ignore the data if it is.
2646 Affected file silcd/packet_send.c.
2648 * Define inline to __inline on native WIN32 compilation.
2649 Affected file includes/silcwin32.h.
2651 * Added some explicit type casts for inline code since MSVC
2652 require them. Affected files lib/silcutil/silcbuffer.h,
2653 lib/trq/silcdlist.h and lib/trq/silclist.h.
2655 * Print warning in log files from now on if the packet
2656 decryption fails. Affected file silcd/server.c.
2658 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2660 * Changed the `say' client operation's interface to accept
2661 new `type' argument to indicate the type of the message sent
2662 by the library. The application may filter the library's
2663 messages according the type. The affected file is the
2664 lib/silcclient/silcapi.h.
2666 * Added two new functions to lib/silcclient/silcapi.h:
2667 silc_client_del_client and silc_client_del_client_by_id.
2668 Affected file lib/silcclient/idlist.c.
2670 * Moved the clientincludes.h from includes/ to silc/ and
2671 serverincludes.h from includes/ to silcd/.
2673 * The modes for the CMODE and CUMODE are now passed as
2674 uint32 for application with COMMAND_REPLY. The affected
2675 file is lib/silcclient/command_reply.c.
2677 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * /WHOIS without arguments shows client's own information.
2680 Affected file lib/silcclient/command.c.
2682 * Changed PING to not accept any arguments. The specs
2683 says that client can ping only the connected server so
2684 requiring an argument is not needed. Affected file is
2685 lib/silcclient/command.c.
2687 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Fixed a fatal bug in private message sending and reception
2690 encryption and decryption when using private message keys.
2691 The implementation was incorrect and did not follow the
2692 specification. It causd that some of the message were
2693 lost since it did not use the sending and receiving keys
2694 as the protocol suggests. This has been fixed and will cause
2695 incompatibilities with older clients when sending private
2696 message encrypted with private message keys. Affected files
2697 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2698 and various other in Irssi SILC Client.
2700 Added `responder' boolean argument to the functions
2701 silc_client_add_private_message_key[_ske] to indicate when
2702 the key is added as responder or initiator of the key
2705 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2707 * Removed the silc_ske_check_version function and created
2708 a SilcSKECheckVersion callback. Added also a function
2709 silc_ske_set_callbacks that is now used to set all SKE
2710 callbacks. The callback functions are not given to
2711 the SKE functions anymore, but this function is used to
2714 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2716 * Added `silc_version' argument to the silc_client_alloc
2717 to define the version of the application for the library.
2718 The library will use the version string to compare it
2719 against the remote host's (usually a server) version
2720 string. Affected file lib/silcclient/silcapi.h
2722 * Added the KE protocol context to Key Agreement context
2723 in client library so that we can abort the SKE if it
2724 is in process when we get timeout. Affected file is
2725 lib/silcclient/client_keyagr.c.
2727 * Do not resolve the client ID forever if it returns in the
2728 first time that such client does not exist. This was done
2729 for example with private message. Affected file is
2730 lib/silcclient/client_prvmsg.c.
2732 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Do not add regex.h for WIN32. The affected file
2735 includes/silcincludes.h.
2737 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2738 not work yet 100%. It generates the DLL's automatically
2739 when compiling with --with-win32 under cygwin.
2741 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * lib/contrib/regex.c is not compiled on WIN32.
2745 * Added silc_net_get_socket_opt function to the
2746 lib/silcutil/silcnet.h.
2748 * Added includes/silcwin32.h for WIN32 specific includes
2751 * Do not use ptime structure or any of the posix process
2752 functions on WIN32 in lib/silccrypt/silrng.c.
2754 * Added silc_gettimeofday to provide generic function
2755 for struct timeval on all platforms. Added the function
2756 to lib/silcutil/silcutil.h.
2758 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2761 library as they clearly belong there. As a plus side we
2762 can make the actual socket connection routines platform
2765 Added also new generic function silc_socket_read and
2766 silc_socket_write (that used to be silc_packet_[read/write].
2767 The implementation of these are platform specific.
2769 * Added WIN32 specific routines of silc_socket_[read/write]
2770 to lib/silcutil/win32/silcwin32sockconn.c.
2772 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Added preliminary support for native WIN32 compilation under
2775 cygwin (using the -mno-cygwin option for GCC) to the
2776 ./configure.in.pre. The --with-win32 now prepares the
2777 compilation for native WIN32.
2779 * Rewrote the SILC Scheduler interface in the file
2780 lib/silcutil/silcschedule.h. The scheduler is now context
2781 based and does not have anymore any global static scheduler.
2782 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2783 and created lib/silcutil/win32 directory for WIN32 based
2786 * Added Unix specific network routines to the
2787 lib/silcutil/unix/silcunixnet.c and the old
2788 lib/silcutil/silcnet.c includes now only generic routines.
2790 Added WIN32 specific network routines to the
2791 lib/silcutil/win32/silcwin32net.c.
2793 * Added Unix specific utility functions from the
2794 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2796 * Added WIN32 SILC Scheduler to the file
2797 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2800 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2802 * Do not handle JOIN notify in the server if the target client
2803 is not registered (idata->registered == FALSE). The affected
2804 file is silcd/packet_receive.c.
2806 * Update the nickrec->founder in event_cumode in the Irssi SILC
2807 client. Affected file irssi/src/silc/core/silc-channels.c.
2809 * Fixed the CUMODE_CHANGE notify handling in the server when
2810 server and router are announcing their clients on channels.
2811 Now the mode changes are saved and notified correctly. The
2812 affected file is /silcd/packet_receive.c.
2814 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2815 They really did not replace the cache entry in the ID Cache.
2816 Now they do that. Affected file silcd/idlist.c.
2818 * Fixed the KICK notify handling in the Irssi SILC client to
2819 update the channel records so that the kicked client does not
2820 appear to be on the channel. The affected file is
2821 irssi/src/silc/core/silc-channels.c.
2823 * Always update the conn->current_channel when executing command
2824 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2826 * Fixed the KILL notify handling in Irssi SILC client to remove
2827 the killed client on all channels.
2829 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Fixed the silc_parse_command_line to remove extra spaces
2832 from the start and end of the arguments. Affected file is
2833 lib/silcutil/silcutil.c.
2835 * Cancel and free any active protocol in the function
2836 silc_server_close_connection. Affected file silcd/server.c.
2838 * Cancel and free any active protocol in the function
2839 silc_client_close_connction. Affected file is
2840 lib/silcclient/client.c.
2842 * Do not execute the KILL command for clients that are in
2843 history (ie. they are not in the network). Affected file is
2846 * Fixed KILL notify handling, client does not crash anymore.
2847 Affected file irssi/src/silc/core/silc-channels.c.
2849 * Reduced the default packet buffer size from 2048 to 1024 in
2850 lib/silccore/silcpacket.c.
2852 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2853 counter to the SKE context that is incresed when the SKE library
2854 performs async operation outside the library. If the outside
2855 process frees the SKE context and FREED status will be set
2856 and the library will detect after the sync operation that the
2857 libary is freed. The affected files are
2858 lib/silcske/silcske[_status].[ch].
2860 * Resolve the client entry information in the function
2861 silc_client_channel_message to assure that NULL pointer is not
2862 passed as client entry to the application. */
2864 * Fixed the task timeout calculation to assure that there is
2865 never negative timeouts. The affected file is
2866 lib/silcutil/silcschedule.c.
2868 * Fixed the channel user mode notification sending in server.
2869 It was sent point-to-point to the router (or to server by router)
2870 but it needs to be destined to a channel. The routines now
2871 supports sending the channel user mode notifys to the channels
2872 when announcing clients and channels. Affected files are
2873 silcd/server.c and silcd/packet_receive.c.
2875 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2876 It did not actually replace the old channel entry in the cache.
2877 Affected file lib/silcclient/client_notify.c.
2879 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2881 * Fixed a possible crash in silc_packet_send_prepare. It now
2882 assures always that there is enough space in the buffer and
2883 at the tail area of the buffer (for MAC).
2885 Fixed the inbound buffer reallocation in silc_packet_read.
2886 It was old code and did not handle the reallocation correctly.
2889 The affected file is lib/silccore/silcpacket.c.
2891 * Fixed buffer overflow in silc_parse_nickname in the file
2892 lib/silcutil/silcutil.c.
2894 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * make install generates new server keys only if there is not
2899 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2901 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2902 Added check that if the NOREPLY is set then we will not send
2903 the away message. This avoids infinite loop of away messages
2904 if both clients are away. The affected file is
2905 lib/silcclient/client_prvmsg.c.
2907 * Fixed client crash if /NICK was given without arguments.
2908 Affected file lib/silcclient/command.c.
2910 * Server does not send the invite list in INVITE command back
2911 to the client if the list was not altered. Added this notion
2912 to the protocol spec as well. Affected file silcd/command.c.
2914 Fixed possible crash in INVITE command by checking the
2915 value of silc_server_get_client_route command.
2917 * Fixed the INVITE notify type handling. The arguments are now
2918 taken in correct order and client does not crash. The affected
2919 file is irssi/src/silc/core/silc-channels.c.
2921 Removed the "Inviting xxx to channel" message from the
2922 client library away and let the application handle it.
2923 Affected file lib/silcclient/command.c. Added that message
2924 to Irssi SILC client's message formats.
2926 * Fixed CMODE command crash in client. It now checks the
2927 amount of arguments correctly and does not crash. The affected
2928 file is lib/silcclient/command.c.
2930 * Do not create new channel automatically in silc_channels_join
2931 but check whether the channel by that name already exists.
2932 Affected file irssi/silc/core/silc-channels.c.
2934 * Do not send the SERVER_SIGNOFF to router if the disconnected
2935 entity was the router. Affected file silcd/server.c.
2937 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2938 SILC client as it was missing from there.
2940 Added the handling of the KICK notify to the Irssi SILC client
2941 as it was missing. Added "you have been kicked" message to
2942 Irssi SILC client's message modules formats.
2944 Added the handing of the KILL notify to the Irssi SILC client
2945 as it was missing. Added the kill message module formats
2948 The affected file is irssi/src/silc/core/silc-channels.c.
2950 * The router did not save the channel mode the server announced.
2951 Affected file silcd/packet_receive.c.
2953 * Fixed a possible crash in INFO command in server. If the
2954 server did not provide the server info it crashed. Affected
2955 file silcd/command.c.
2957 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Fixed the GETKEY command in the server to check also the
2960 global list. Otherwise the GETKEY would not work correctly
2961 in normal SILC server. Affected file silcd/command.c.
2963 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Fixed GETKEY crash, it crashed if the command did not succseed.
2967 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2970 is now real and not just an macro interface to GMP.
2972 Removed the entire GMP from the source tree and imported new
2973 NSS MPI library instead. Reason for removing GMP is that it is
2974 extremely large and compiles extremely slow. The NSS MPI
2975 is only a few files and compiles in less than 10 seconds.
2976 The speed is also about the same as GMP. The MPI is imported
2977 to lib/silcmath/mpi.
2979 If the system has GMP installed we will still use the GMP.
2980 If it is not then the NSS MPI will be compiled.
2982 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Merged a long nickname (127 characters long) crash bugfix from
2985 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2987 * Merged a freed memory reference bugfix from Irssi CVS tree.
2988 Affected file irssi/src/core/commands.c.
2990 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added the server's public key sving and verification to the
2993 server when performing the SKE. This was missing and the
2994 remote server's (or router's) public key was accepted without
2995 checking whether we have it previously or trust it at all.
2996 Affected file silcd/protocol.c.
2998 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Check in the silc_server_timeout_remote if protocol is active
3001 and make sure that the protocol's final callback is called so
3002 that all memory if freed. Affected file silcd/server.c.
3004 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * silc_server_whois_send_reply crashed the server if the nickname
3007 was 127 characters long. Affected file silcd/command.c.
3009 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Added sanity check to the silc_server_new_client. If the hostname
3012 is provided inside username then check that the provided hostname
3013 really is the same as the resolved one. If the hostname was not
3014 resolved then check it from the public key. Affected file is
3015 silcd/packet_receive.c.
3017 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3018 if the server disconnected us and the connection is not valid
3019 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3021 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3022 the library to the lib/silcutil/silcutil.[ch].
3024 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Close log file after open. Affected file
3027 lib/silcutil/silclog.c.
3029 * Check whether sock == NULL in silc_client_send_packet and return
3030 if it is. Affected file lib/silcclient/silcclient.c.
3032 * Check rec->entry == NULL in the Irssi SILC Client before
3033 sending the channel message. Affecte file is
3034 irssi/src/silc/core/silc-servers.c.
3036 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Merged a splitted window bugfix from Irssi CVS tree. The
3039 affected file is irssi/src/fe-text/textbuffer-view.c.
3041 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3042 It did not print nickname.
3044 * Improved the distributions system a bit.
3046 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3049 irssi/src/fe-text/gui-window.c.
3051 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3052 to in-active server. The affected file is
3053 irssi/src/silc/core/client_ops.c.
3055 * Resolve the client in USERS command reply if the entry does
3056 not have username resolved. The affected file is
3057 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3058 command to WHOIS command to really resolve stuff. The USERS
3059 is not used any more in any critical section so WHOIS can
3060 be used even though it might be slower than IDENTIFY.
3062 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3065 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Changed the protocol API a bit more consistent in the
3068 lib/silccore/silcprotocol.[ch].
3070 * Changed the following headers to ROBODoc format:
3072 lib/silccore/silcpayload.h
3073 lib/silccore/silcprotocol.h
3074 lib/silccore/silcsockconn.h
3076 All core library headers are now formatted.
3078 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Fixed a bug in Irssi SILC client; do not show that you are
3081 server/router operator if you really are not. Affected file is
3082 irssi/src/silc/core/client_ops.c.
3084 * Renamed silc_command_free_payload to silc_command_payload_free.
3085 Affected file lib/silccore/silccommand.h
3087 * Added silcmath.h to include the prototoypes of various routines
3088 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3091 * Changed the following headers to ROBODoc format:
3093 lib/silccore/silcchannel.h
3094 lib/silccore/silccommand.h
3095 lib/silccore/silcid.h
3096 lib/silccore/silcidcache.h
3097 lib/silccore/silcmode.h
3098 lib/silccore/silcnotify.h
3099 lib/silccore/silcpacket.h
3100 lib/silcmath/silcmath.h
3102 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Added checking to the server code not to start the server if
3105 ciphers and stuff are not configured properly. Affected files
3106 silcd/serverconfig.[h] and silcd/server.c.
3108 * Changed the layout of the header files of the public interfaces
3109 in the SILC libraries. The new layout supports ROBODoc
3110 documentation tool (and some others) so that it is easy to create
3111 a library reference manual. All the other headers and source
3112 code must still follow the CodingStyle document. Also source
3113 code must not include these ROBODoc stuffs, only the headers.
3114 Furthermore, all public interface headers must now be named
3115 by using `silc' prefix, example: silcapi.h, silccipher.h.
3116 Some files were renamed due to this. All the other headers
3117 must not be used as public interfaces. I will update the
3118 CodingStyle document later. Changed following headers, so far:
3120 lib/silcclient/silcapi.h
3121 lib/silccore/silcauth.h
3122 lib/silccore/silcprivate.h
3123 lib/silccrypt/silcdh.h
3125 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Removed silc_client_packet_send_flush from the client library
3130 as it is not needed. Affected file lib/silcclient/client.[ch].
3132 * Added printing of message of unresolved authentication method
3133 to the Irssi SILC client. Added it to the module formats.
3134 Removed the same message from the client library.
3136 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Added new distribution feature, DISTLABEL. Every distribution
3139 can define own preprocessor label that can be used in the
3140 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3141 file distributions, acconfig.h.pre and prepare.
3143 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Added Makefile.defines_int to include the actual definitions
3146 for Makefile.defines.in. Tested the new distribution system,
3147 created distributions and tested installation.
3149 * Added AWAY message printing to the Irssi SILC client. Added
3150 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3152 * Added SCONNECT command to call the SILC's CONNECT command.
3153 Cannot use CONNECT directly since Irssi uses that internally.
3154 Affected file irssi/src/silc/core/silc-servers.c.
3156 Added ACTION local command. It is same as ME command but takes
3157 the channel as mandatory argument.
3159 Rewrote some of the Irssi's help files to suite for SILC
3162 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Added Makefile.defines[.in] that should for now on be included
3165 in all Makefile.am file in the source tree. That file includes
3166 all common compilation definitions for SILC source tree.
3168 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Minor changes to the ./prepare script to change the package
3171 name according the distribution name to the configure.in.
3173 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3175 * Created new distribution system. Added file `distributions'
3176 that defines all the distributions that can be created out of
3177 the SILC source tree. The ./prepare script now reads that
3178 file to determine how to prepare the distributions. The
3179 first argument to the ./prepare is the name of the distribution
3180 and second is the version of the distribution. If given
3181 without arguments it creates the default (toolkit) distribution
3182 with the default version (defined in ./prepare).
3184 All Makefile.am files that are subject to the distributions
3185 are now named as Makefile.am.pre. These are ./Makefile.am
3186 and lib/Makefile.am. Others may be changed later.
3188 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Added invite list, ban list, some key management and connection
3191 error message printing to module formats in the Irssi SILC client.
3193 * Added new silc_client_set_away_message to set the away message
3194 that is back to the person who sent private message. The
3195 affected file lib/silcclient/silcapi.h and the
3196 lib/silcclient/client_prvmsg.c.
3198 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Fixed the private message sending in the Irssi SILC client,
3201 added local command KEY to the Irssi SILC client.
3203 Added key management and key agreement message formats to the
3204 irssi/src/fe-common/silc/module-formats.[ch].
3206 Added USERS (alias WHO) printing, server/router operator
3207 indication and LIST command printing to the module formats.
3209 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Fixed channel joining notify handling, cumode notify handling
3212 from Irssi SILC client.
3214 * Added SILC specific module-formats to the Irssi SILC client so
3215 that SILC specific message hilighting, colors etc is possible.
3216 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3218 Added channel mode, channel user mode, actions, notices,
3219 whois and whowas printing to the the module-formats.c.
3221 * Fixed a bug in channel deletion in the server. The channel
3222 is not left to the cache even if the channel founder auth mode
3223 is set when there are no users anymore on the channel. Affected
3224 file silcd/server.c.
3226 * The silc_net_localhost now resolves the entire hostname including
3227 the domain name. Affected file lib/silcutil/silcnet.c.
3229 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3231 * Changed the ask_passphrase client operation to be ascynchronous.
3232 It has now a completion callback and a context that the
3233 application must call after it has got the passphrase from
3234 the user. Affected files lib/silcclient/silcapi.h,
3235 lib/silcclient/protocol.c, lib/silcclient/command.c and
3238 Added SilcAskPassphrase callback that the application calls
3239 to deliver the passphrase to the library.
3241 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3242 The public key verification and especially a certificate
3243 verification is asynchronous procedure.
3245 Added new SILC_SKE_STATUS_PENDING status to indicate the
3246 request is pending and a callback will be called to finalize
3249 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3250 indicate that remote end did not send its public key (or
3251 certificate), even though we require it. Added check for this
3252 condition in the SKE. This was a security bug, now fixed.
3254 Defined new SilcSKEVerifyCbCompletion callback that is called
3255 when the verification process is completed.
3257 The affected files lib/silcske/silcske_status.h and
3258 lib/silcske/silcske.[ch].
3260 * Changed the verify_public_key client operation to be async
3261 as well. Defined SilcVerifyPublicKey callback that is used to
3262 indicate the success of the public key verification process.
3264 Changed the server and client to use the new async client
3267 * Changed the Irssi SILC client's internal scheduler to be called
3268 twice as many times as it used to be. As a result the client
3269 should be a bit faster now. Affected file is
3270 irssi/src/silc/core/silc-core.c.
3272 * Added support to Irssi SILC client of asynchronous public key
3273 verification and passphrase inquiry. Affected file is
3274 irssi/src/silc/core/silc-core.c.
3276 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Do not say "You have left channel %s" in client library.
3279 Moved it to the application. Affected files are
3280 lib/silcclient/command.c and silc/client_ops.c.
3282 * Fixed silc_client_get_clients. Command context was not
3283 duplicated and was freed memory in the callback. Affected
3284 file lib/silcclient/idlist.c.
3286 * Do not say "you are now talking..." on JOIN command in the
3287 client library. The appliation must handle it.
3289 * Do not say ".. changed topic to" in command reply in the
3290 client libary. The application must handle it.
3292 * Fixed TOPIC command sending in the client library.
3294 * Fixed a memory leak in silc_client_command_free in the file
3295 lib/silcclient/command.c.
3297 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Imported a modified version of Irssi client to the source tree.
3300 The Irssi will be used to create a new client called
3301 Irssi SILC. Imported to irssi/.
3303 Added silc_core_init_finish function to the Irssi. Affected
3304 file irssi/configure.in.
3306 A lot changes in the Makefile.ams around the irssi tree.
3308 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Do not rehash if the new size is same as the old size of the
3311 hash table, in the silc_hash_table_rehash*. The affected file
3312 lib/silcutil/silchashtable.c.
3314 * Replaced hash_table_del_by_context calls from the server
3315 (when channel->user_list and client->channels) to the
3316 hash_table_del as it is sufficient and faster.
3318 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added silc_hash_table_list, silc_hash_table_get and the
3321 SilcHashTableList structure to provide an alternative way to
3322 traverse the hash table. The affected files are
3323 lib/silcutil/silchashtable.[ch].
3325 * Changed the server's idlist routines to use the hash table
3326 routines to optimize the code.
3328 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Replaced the client entry's `channel' list and channel entry's
3331 `user_list' list to hash tables for optimized lookup. Changed
3332 the code to use the hash table interface around the code.
3333 Affected file lib/silcd/idlist.[ch].
3335 * Added `auto_rehash' boolean argument to the function
3336 silc_hash_table_alloc to indicate whether the hash table should
3337 auto-rehash when it thinks is appropriate time. It will
3338 increase the hash table size if the there is twice as much
3339 entries in the table than the size of the table, and will
3340 decrease the size if there are twice as less entries than
3341 the size of the table.
3343 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3347 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * silc_idcache_purge_by_context deletes the entry now by context
3350 as it is supposed to do. Affected file lib/silccore/idcache.c.
3352 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3353 client is not anymore valid (WHOWAS givens the info) and not
3354 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3356 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Removed the `data' and `data_len' arguments from the ID Cache
3359 interfaces and added `name' argument. ID Cache does not handle
3360 anymore the binary data only a names associated with given ID.
3362 * When hashing a Client ID with silc_hash_id the entire ID is
3363 not hashed anymore, instead only the hash of the Client ID is
3364 hashed. This way we can access the Client ID from the cache
3365 with Client ID but with the hash of the ID (which is a hash of
3366 the nickname) as well without any difference in performance.
3368 Added also silc_idcache_find_by_id_one_ext to do one on one
3369 searching when we have the actual ID. Added also function
3370 silc_hash_client_id_compare. The affected files are
3371 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3373 * When hashing the name associated with a ID it is always done
3374 in lowercase. This way we can access the cache without worrying
3375 about case-sensitivity, even though, for example nicknames are
3378 * Fixed a bug in server with channel message sending. It put
3379 wrong ID type as destination ID. The affected file
3380 silcd/packet_send.c.
3382 * silc_idcache_del_by_context now deletes from all hash tables
3383 by context. Affected file lib/silccore/idcache.c.
3385 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Changed the client library to use the new ID Cache interface.
3388 Changes around the source tree.
3390 * Added silc_hash_table_rehash_ext to rehash with specific
3391 hash function. Affected file lib/silcutil/silchashtable.[ch].
3393 * Added silc_hash_string_compare to compare two strings in the
3394 hash table. Affected file lib/silcutil/silcutil.[ch].
3396 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Added new function silc_idcache_del_by_context into the
3399 lib/silccore/idcache.[ch].
3401 * Changed the server's ID list routines to use the new ID Cache
3402 interface. Changes around the source tree.
3404 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3406 * Added silc_hash_table_del[_by_context]_ext functions in to the
3407 lib/silcutil/silchashtable.[ch].
3409 Removed silc_hash_table_find_all* routines and added new
3410 silc_hash_table_find_foreach to replace them.
3412 Added silc_hash_table_replace_ext function as extended
3413 replacing function. Separated the simple hash table interface
3414 from the extended hash table interface in the file
3415 lib/silcutil/silchashtable.h.
3417 * Fixed minor bugs and changed it to use some of the new
3418 hash table functions in lib/silccore/idcache.c
3420 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3422 * Added new function silc_hash_table_find_all to return all keys
3423 in the hash table by the specified key. As the hash table is
3424 collision resistant it also makes it possible to have several
3425 duplicate keys in the hash table. This function may be used to
3426 find all of the keys from the hash.
3428 Added user_context arguments to the SilcHashFunction,
3429 SilcHashCompare and SilcHashDestructor to deliver user specified
3432 Added new fuctions silc_hash_table_find[_all]_ext to do
3433 extended lookup with specified hash and compare functions and
3434 specified user contexts.
3436 Added new function silc_hash_table_add_ext to add the key
3437 with specified hash function and user context.
3439 Added new function silc_hash_table_foreach to traverse all
3440 entrys in the hash table. Added SilcHashForeach callback
3443 Added new function silc_hash_table_del_by_context to delete
3444 the entry only if the context associated with the key matches.
3446 Affected files are lib/silcutil/silchashtable.[ch].
3448 * Removed silc_hash_[server/client/channel]_id and added just
3449 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3450 silc_hash_id_compare to compare two ID's using as the hash table
3451 comparison function. Added also silc_hash_data to hash
3452 binary data and silc_hash_data_compare to compare it.
3454 * Removed silc_idlist_find_client_by_hash as it is not needed
3455 anymore. Affected file silcd/idlist.[ch].
3457 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3458 to use internally the SilcHashTable. The new ID Cache is a lot
3459 faster than the old one. Some of the ID Cache interface was also
3460 rewritten and obsolete and stupid functions were removed.
3462 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3464 * Added entry_count field to the SilcHashTable to keep the number
3465 of the entries in the table. Implemented the function
3466 silc_hash_table_rehash. Added new function
3467 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3469 Fixed a minor bug in silc_hash_table_free.
3471 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3472 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3473 into the lib/silcutil/silcutil.[ch].
3475 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Implemented a collision resistant hash table into the
3478 lib/silcutil/silchashtable[ch]. See the header and the source
3479 for the SilcHashTable API.
3481 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Merged dotconf version 1.0.2 into lib/dotconf.
3485 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Do not compile anything in lib/silcsim/* if the SIM support
3488 is not enabled. The tree should now compile without problems
3491 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Compiled the SILC under cygwin. Compiled and tested briefly
3494 without problems. More tests needed. The SIMs didn't compile
3497 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3499 * Fixed possible crash in silc_get_username in the
3500 lib/silcutil/silcutil.c.
3502 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Fixed a va_arg in silc/client_ops.c.
3506 * Oops, RC5 routines were named AES and caused some problems
3507 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3509 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3511 * Added new SilcIDIP structure into the lib/silccore/id.h and
3512 replaced the old `ip' fields from all SILC ID's to that type.
3513 This is a step towards IPv6 support.
3515 The silc_id_get_len takes now the ID as an extra argument.
3516 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3517 both IPv4 and IPv6 based ID's.
3519 The affected files are lib/silccore/id.[ch] and other files
3520 around the tree using these routines.
3522 * Removed the ID length arguments in server from various
3523 silc_server_send_notify_* routines -> they are not needed
3526 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Fixed memory leak in silc_encode_pem_file in the file
3529 lib/silcutil/silcutil.c.
3531 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Check minor version as well in the SKE. Affected files are
3534 silcd/protocol.c and lib/silcclient/protocol.c.
3536 * Added --identifier option to the server so that an identifier
3537 can be when creating the public key for the server. Affected
3538 file is silcd/silcd.c.
3540 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3541 lib/silccrypt/silcpkcs.c.
3543 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Register default ciphers and stuff when using -C option with
3546 the server. Affected file sildc/silcd.c.
3548 * Put back the servers public key filename format, it is better
3549 than the new one. For now, the client keys are saved with the
3550 new filename format. The affected file silc/client_ops.c.
3552 * Implemented the Cipher API for the rest of the ciphers that
3553 did not implement it or implemented it the wrong way.
3555 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Register default ciphers and stuff when using the -S option
3558 in the client. Affected file silc/silc.c. Same also when
3559 creating new key pair with -C option.
3561 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Fixed the silc_verify_public_key client operation function to
3564 save the public keys differently. The fingerprint is now
3565 used as filename and not the hostname. This way also the
3566 client keys are saved uniquely and not with hostnames. The
3567 affected file is silc/client_ops.c.
3569 * Trimmed the silc_hash_fingerprint function to remove extra
3570 whitespaces from the end of the fingerprint. The affected
3571 file is lib/silccrypt/silchash.c.
3575 * Added silc_cipher_register_default function to register all
3576 default ciphers. It can be used when configuration files
3577 does not exist and the application does not want any specific
3578 ciphers in any specific order.
3580 The SilcDList is now used as silc_cipher_list dynamically
3581 allocated cipher list. Removed the static list all together
3582 and now all ciphers must be allocated to the dynamic list.
3583 The silc_cipher_alloc routine was changed to check only the
3586 All silc_cipher_* routines that used to return int returns
3589 The affected files lib/silccrypt/silccrypt.[ch].
3591 * The same thing was done to silc_hash_* as for silc_cipher_*
3592 routines. Affected files lib/silccrypt/silchash.[ch].
3594 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3595 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3596 Added also silc_pkcs_[un]register[_default] functions.
3597 Removed the data_context from the PKCS API.
3599 * Added silc_hmac_register_default function to register default
3600 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3601 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3602 to unregister all hmacs at once.
3604 * Register the default ciphers, hash functions, PKCSs and HMACs
3605 if client's configuration file does not exist. The affected
3608 * The client did not load the hash functions from the SIM
3609 modules at all. Added support for this. Affected file is
3610 silc/clientconfig.c.
3612 * When decoding public key with silc_pkcs_public_key_decode, check
3613 the supported algorithm only if PKCS are registered. Affected
3614 file lib/silccrypt/silcpkcs.c. The same was done with the
3615 silc_pkcs_private_key_decode.
3617 * Fixed the SILC List routines to keep the list always in order.
3618 It used to change the list's order when traversing the list but
3619 not it preserves the order. Affected file lib/trq/silclist.h.
3621 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Added the client library to use the SilcSocketConnection's
3624 reference counter (by silc_socket_dup) to prevent the bug that
3625 the socket object may be freed underneath async operation.
3627 * The name resolv library checking fixes in the configure.in.pre.
3630 * Created new version of the protocol drafts for future
3631 development. The -03 drafts are the ones that will be changed
3632 in the trunk now and the -02 will remain as they are.
3634 * Send list of CUMODE notifys to the router when announcing
3635 the channel users to the router. Affected file silcd/server.c.
3636 If the router receiving channel founder CUMODE for a channel
3637 that already has channel founder it will send CUMODE notify
3638 to the sender to remove the channel founder rights from the
3639 announced client. Affected file silcd/packet_receive.c.
3641 * The CUMODE notify may now use Server ID as well as the entity
3642 who changes the mode. Updated protocool specs.
3644 * Updated INSTALL and README files.
3646 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * New web pages in the http://silc.pspt.fi. The pages was
3653 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Implemented the [DenyConnectin] config section in the server.
3656 Added silc_server_config_denied_conn to check whether incoming
3657 connection is denied. Affected file silcd/serverconfig.[ch].
3659 * Do not check the ports when checking the incoming configuration
3660 data if the port is 0, meaning any. Affected file is
3661 silcd/serverconfig.c.
3663 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Fixed buffer overflow in silc_string_compare in the file
3666 lib/silcutil/silcutil.c.
3668 * Fixed double free in silc_server_command_leave in the file
3671 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Fixed the version checking in the server. Affected file is
3676 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Fixed the configuration data fetching when accepting new
3679 connections in the server. Affected file silcd/server.c.
3681 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Added `sender_entry' argument to the function
3684 silc_server_packet_relay_to_channel so that we can check
3685 whether some destination actually belongs to the same route
3686 the sender belongs (ie, we must not resend the packet to the
3687 sender). Affected file silcd/packet_send.[ch].
3689 * Added `servername' field to the SilcClientEntry in the server
3690 to hold the name of the server where client is from. Affected
3691 file is silcd/idlist.h.
3693 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Moved the channel message encrypting in the router betwen
3696 router connections from silc_server_channel_message to the
3697 silc_server_packet_relay_to_channel since we want to check
3698 whether we have anybody channel before encrypting anything.
3699 Affected files silcd/packet_[receive/send].c.
3701 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3703 * Fixed the [AdminConnection] server config section to support
3704 multiple entries. Affected file silcd/serverconfig.c.
3706 * Added support into the server to check the validity of the
3707 incoming connection before executing any KE or authentication
3710 * The connection configuration is now saved to the KE and
3711 connection auth protocol contexts and not fetched anymore in
3712 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3714 * The local hosts listenning address and port is also resolved
3715 now when starting the server. We want to have the socket object
3716 to include the real address and port for the listener. Added
3717 new function silc_net_check_local_by_sock into the files
3718 lib/silcutil/silcnet.[ch].
3720 * Fixed a broadcast bug in server -> do not broadcast if we
3723 * Fixed a routing bug. Do not route broadcast packets ever.
3724 Broadcast packets must be processed always and not routed since
3725 they may be destined to some other host than yourself and thus
3726 would get routed without no good reason. Affected file is
3729 * Added function silc_server_config_is_primary_route to check
3730 whether primary router connection has been configured (a router
3731 configuration that we are initiating). If there is not, we
3732 will assume that there is only two routers in the SILC network
3733 and we will use the incoming router connection as our primary
3734 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3736 * Changed the order of the broadcasting. Broadcast _after_ the
3737 packet has been processed not before. Affected file is
3740 * Fixed a [ClientConnection] parsing bug. The port was never
3741 parsed correctly thus resulting to port 0. Affected file
3742 silcd/serverconfig.c.
3744 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3745 argument and did not set the broadcast packet flag. Affected
3746 file silcd/packet_send.c. Fixed same bug in the function
3747 silc_server_send_notify as well.
3749 * If we receive NEW_ID packet for our own ID in the server, ignore
3752 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Removed the nickname from the Private Message Payload.
3757 Updated the code and the protocol specs.
3759 * Updated protocol specs for submitting to the IETF.
3761 * Tweaked the Random Number Generator a bit. Affected file
3762 lib/silccrypt/silcrng.c. Exported a new function
3763 silc_rng_[global]_add_noise which can be used to add more
3766 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Do not parse packets with different timeout when protocol
3769 is active -> may cause problem with rekey. Affected file
3772 * When server receives signoff notify it must not create
3773 new channel key if the client is on any channels since the
3774 sender of the signoff notify will create it.
3776 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Added printing of error messages during SKE protocol from the
3779 failure packet sent by server during SKE. Affected file
3782 * Removed the client's failure_callback handling with timeout
3783 and handle it immediately when received.
3785 * The SKE library returned wrong type in SUCCESS and FAILURE
3786 packets. They must be 32 bit MSB not 16 bit MSB.
3788 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Ok, rewrote the logic of the re-key and now it seems to work.
3791 I tested it on high traffic with frequent re-keys without
3792 problems. Added hmac_receive (and renamed hmac to hmac_send)
3793 in SilcClientConnection in lib/silcclient/client.h and
3794 in SilcIDListData in silcd/idlist.h. Also, removed the
3795 SilcPacketParserContext's cipher and hmac fields as they are
3796 not needed anymore and actually caused some problems when
3797 the ciphers and hmac's changed underneath the packet parser.
3799 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * If re-key protocol is active then process the incoming packets
3802 synchronously since we must assure that icoming packets encrypted
3803 with the old key is processed before the new keys is set to
3804 use. This is true other packets than for REKEY packets.
3805 Affected file silcd/server.c. The same was done to client library
3806 as well, affected file lib/silcclient/client.c.
3808 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Fixed bug in client and server to accept the force send if
3811 the packet is send from silc_[server/client]_packet_process
3812 function. Otherwise the packets are never delivered, oops.
3814 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3816 * Disable force sending of packets when REKEY protocol is active.
3817 We must assure that no packet is sent directly when rekey is
3818 performed. All packets must be sent through packet queue.
3819 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3820 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3821 function is silc_[server/client]_packet_send_real to check
3824 * Replaced the SIM paths from example config files to
3825 /usr/local/modules. Also, make install creates now
3826 /usr/local/silc/logs directory to hold all the SILC server
3829 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Made the configure.in.pre work on Solaris. Patch by salo.
3833 * Made all ciphers compatible with non-x86 machines. Defined
3834 CBC mode macros into lib/silccrypt/ciphers_def.h.
3836 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3838 * Fixed the make install.
3840 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * When MAC computation fails the silc_packet_decrypt returned 0
3843 even though it was supposed to return -1. Fixed this. The
3844 affected file is lib/silccore/silcpacket.c.
3846 * Do not replace the config files in /etc/silc (in make install)
3847 if they already exist. Affected file ./Makefile.am.
3849 * Do not send re-key packets immediately but through packet queue.
3850 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3852 * Changed silc_net_check_host_by_sock to return FALSE if the
3853 IP/DNS could not be resolved. Though, it returns the IP address
3854 now even if it could not resolve it (but returns also FALSE).
3855 Affected file lib/silcutil/silcnet.[ch].
3857 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Added silc_pkcs_decode_identifier to decode the public key's
3860 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3861 Added also silc_pkcs_free_identifier. Added also new context
3862 SilcPublicKeyIdentifier.
3864 * Added -S option to the silc client. It is used to dump the
3865 contents of the specified public key file.
3867 * Changed the PKCS api to return the public key length when
3868 setting the public key.
3870 * Fixed a fatal bug in the public and private key file loading.
3871 Affected file lib/silccrypt/silcpkcs.c.
3873 * Execute the packet parsing for client with zero (0) timeout
3874 if the protocol is active. Affected file silcd/server.c.
3876 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Made the key generation options to the silcd program. Added
3879 -C option, equivalent to client's option.
3881 * Added new [ServerKeys] config section to the server. It
3882 configures the server's public and private key.
3884 * Defined generic Public Key Payload into the protocol
3885 specification to send specific type of public keys and
3888 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3889 public key or certificate.
3891 * Implemented the GETKEY command to the server and to the
3892 client library and on user interface.
3894 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3896 * Made preliminary `make install' work.
3898 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Added SilcServerRekey context into silcd/idlist.h.
3902 * Added the PFS support as defined in the specification to the
3903 SKE protocol. Affected files lib/silcske/*.c.
3905 * Added `ske_group' field to the SilcServerRekey context to hold
3906 the number of the SKE group that is used with PFS in re-key.
3907 Affected file silcd/idlist.h.
3909 * Added PFS re-key support to the server. Affected file is
3912 * Added silc_protocol_cancel to cancel execution of the next
3913 state of the protocol. Affected file is
3914 lib/silccore/silcprotocol.[ch].
3916 * Added the re-key support with and without PFS to the client
3917 library. Re-key is performed once in an hour, by default.
3919 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3920 Added silc_client_rekey_callback and silc_client_rekey_final.
3921 Affected files are lib/silcclient/protocol.[ch] and
3922 lib/silcclient/client.[ch].
3924 * Removed the `hmac_key' and `hmac_key_len' fields from the
3925 SilcClientConnection structure; not needed. Affected file is
3926 lib/silcclient/client.h.
3930 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Do not ask whether user wants to use the negotiated private key
3933 for private messages, just use it. Affected file is
3934 silc/local_command.c.
3936 * Added `send_enc_key' and `enc_key_len' fields to the
3937 SilcIDListData structure since they are needed in the re-key
3938 phase. Affected file is silcd/idlist.[ch].
3940 * Implemented the simple re-key protocol into the server.
3941 Affected files silcd/server.c and silcd/protocol.[ch]. The
3942 re-key will be performed once in an hour, by default.
3944 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3945 Added silc_server_rekey, silc_server_rekey_callback and
3946 silc_server_rekey_final.
3948 * Removed Tunneled flag from the protocol. Updated the code
3949 and the specifications.
3951 * Adde `pfs' field to the SilcIDListData to indicate whether
3952 the PFS is to be performed in the re-key. Affected file is
3955 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3958 int64 of at least the xintXX size. If void * is less that 4
3959 bytes uint32 * will be used. Defined bool as boolean.
3961 * Changed _ALL_ unsigned long and unsigned int to uint32,
3962 unsgined short to uint16 in the source tree.
3964 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3965 not handle clients that has entry->data.registered == FALSE.
3966 They are not in the network anymore. Affected file is
3969 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Implemented the sending of the SERVER_SIGNOFF notify in the
3972 server. Affected file is silcd/server.c.
3974 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3975 Added also silc_notify_payload_encode_args into the
3976 lib/silccore/silcnotify.[ch].
3978 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3979 Affected file silcd/packet_receive.c.
3981 * Implemented the SERVER_SIGNOFF notify handling in the client
3982 library. Affected file lib/silcclient/client_notify.c. Also,
3983 implemnted the printing of the SERVER_SIGNOFF info to the
3984 application. Affected file silc/client_ops.c.
3986 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3987 if the deleting was successful. Affected file silcd/idlist.[ch].
3989 * Added support for public key authentication in the connection
3990 authentication protocol in the client library. Affected file
3991 lib/silcclient/protocol.c.
3993 * Changed the server's silc_idlist_get_clients_by_* interface
3994 to support already allocated array so that new entries may be
3995 added to pre-allocated array. Affected file silcd/idlist.[ch].
3996 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3997 and command replies.
3999 * All command reply functions in the server now calls the
4000 pending command callback even if error occured. This way the
4001 error will be delivered to the client as well. Affected files
4002 silcd/command.c and silcd/command_reply.c.
4004 * Fixed INFO command to return local server's info if no server
4005 was provided. Affected file lib/silcclient/command.c.
4007 * Removed RESTART command for good. Updated the code and the
4010 * Rewrote parts of the task system. It is a bit simpler now.
4011 Removed unsued task priorities. The affected files are
4012 lib/silcutil/silctask.[ch].
4014 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4016 * Moved the USERS printing from the library to the application.
4017 Affected files lib/silcclient/command.c and silc/client_ops.c.
4019 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * Added channel key re-key support. The re-key is perfomed
4024 only by the router and is done once in an hour. Added `rekey'
4025 field to the SilcChannelEntry in the server. Affected files
4026 silcd/server.c and silcd/idlist.h.
4028 * Added silc_task_unregister_by_context into the file
4029 lib/silcutil/silctask.[ch].
4031 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Added SILC_UMODE_GONE mode to indicate when the client is not
4034 present in the SILC network. Added also support to the local
4035 command AWAY that will set this mode. Added support of showing
4036 "xxx is gone" in WHOIS command. The USERS command shows the
4037 gone status as well.
4039 * Fixed setting server and router operator privileges in the
4040 server's UMODE command. Affected file silcd/command.c.
4042 * Merged the SKE KE1 and KE2 payloads into one payload. The
4043 new KE payload is equivalent to the old KE2 payload.
4045 Cleaned up the SKE Start Payload parsing. It now uses the
4046 simple buffer unformatting to do the parsing. A lot faster
4049 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4050 to the SKE that is used to indicate whether both of the SKE
4051 parties should perform authentication. By default only the
4052 responder performs authentication. By setting this flag also
4053 the initiator must do authentication. By default it is unset
4054 since in normal SKE case, client to server connection, only
4055 the responder should do authentication. When doing SKE between
4056 two clients both should perform authentication. Updated the
4057 code and the protocol specs.
4059 * A little fix to IDENTIFY command in the server. Search the
4060 client first by hash not nickname. Affected file is
4063 * Fixed the silc_client_close_connection to support closing
4064 the client to client connections wihtout deleting too much
4065 data. Affected file lib/silcclient/client.c.
4067 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4068 are received if protocol used to be active but is not anymore
4069 the application would crash due to NULL pointer dereference.
4070 Affected files silcd/server.c and lib/silcclient/client.c.
4072 * Added `hash' field to the SilcClientConnection to include
4073 the hash function negotiated in the SKE protocol.
4075 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4076 to set the channel founder authentication data. A client can
4077 claim the founder rights later by providing the authentication
4078 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4079 This way the channel founder can regain the channel founder
4080 privileges even it is left the channel. This works only on
4081 local server and the client must be connected to the same
4082 server to be able to regain the founder rights. Updated the
4083 protocol specs accordingly.
4085 Added support to the CMODE command in the client to set the
4086 founder auth data. Read the README to see how to set it.
4088 Added support to the CUMODE command to claim the founder
4089 rights. Read the README to see how to do it.
4091 Added support for the founder authentication to the Channel
4092 Entry in the server. Affected file silcd/idlist.h.
4094 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4095 server's CMODE command. Affected file silcd/command.c.
4097 * Added the following new functions into lib/silccore/silcauth.[ch]:
4098 silc_auth_get_method and silc_auth_get_data.
4100 * The server now saves the remote hosts public key to the
4101 SilcIDListData pointer. Affected file silcd/protocol.c.
4103 * The normal server now does not remove the channel entry from
4104 the cache if the founder authentication data is set. It used
4105 to remove it if the founder was the last one on the channel on
4106 the server and left the channel. The auth data is saved and
4107 if the channel is re-joined later the old entry is used with
4108 the old auth data. Affected files silcd/command_reply.c and
4111 * Removed the `pkcs' field from the SilcIDListData structure
4112 in the server; it is not used. Affected file silcd/idlist.h.
4114 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Fixed packet processing on slow links. Partial packets were
4117 never re-processed because the incoming data buffer was cleared
4118 by the application. Application must not directly clear the
4119 sock->inbuf, the packet processing routines handle it. Fixed
4120 this in client library and in server.
4122 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Fixed the WHOIS and IDENTIFY send reply function to really
4125 check whether to send list or just one entry. Affected file
4128 * Cleaned up the LEAVE command's channel key distribution. The
4129 affected file silcd/command.c.
4131 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4132 can enforce the channel mode as well. In that case the ID
4133 includes the ID of the server. The code now enforces the
4134 mode change if the router have different mode than the server.
4136 * The notify client operation with CMODE_CHANGE notify can now
4137 return NULL client_entry pointer if the CMODE was not changed
4138 by client. Application must check for this.
4140 * Added <Server ID> argument to INFO command to support server
4141 info fetching by Server ID.
4143 * Added silc_server_announce_get_channel_users to get assembled
4144 packets of channel users of the specified channel. Affected
4145 file silcd/server.[ch].
4147 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4148 was freed underneath the ID Cache.
4150 * Re-announce clients when the server received CHANNEL_CHANGE
4151 notify from the router. Affected file silcd/packet_send.c.
4153 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4156 crashed since it did not handle the fact that there is no cipher
4157 called "3" and didn't check the error condition. Now fixed.
4159 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4160 flag. It can be used to send message requests.
4162 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4164 * Implemented the RESTART command in the client.
4166 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4167 notice type messages. Added notice printing to the user
4170 * The channel keys are not re-generated if the channel's mode
4171 is PRIVKEY, ie private key on the channel exists. Affected
4172 files silcd/server.c and silcd/command.c.
4174 * Fixed a little bug in channel message delivery when channel
4175 private keys are set in the server. Affected file is
4176 silcd/packet_send.c.
4178 * Changed the setting on channel->on_channel = TRUE from the
4179 silc_client_save_channel_key to the JOIN command reply. The
4180 key payload is not received if the private channel key is set.
4181 Affected file lib/silcclient/command_reply.c and the
4182 lib/silcclient/client_channel.c.
4184 * When the CMODE_CHANGE notify is sent and the channel private
4185 key mode is removed the channel key must be re-generated in
4186 other cells as well. Added this support for the router in the
4187 silcd/packet_receive.c.
4189 * Added new local command NOTICE to send notice message on
4190 channel. Affected file silc/local_command.[ch].
4192 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Added new local command ME to the client. It is used to send
4195 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4196 some action. Affected file silc/local_command.[ch].
4198 * Changed channel_message and private_message client operations
4199 to deliver the message flags to the application. Added also
4200 the `flags' arguments to the silc_client_send_channel_message
4201 and silc_client_send_private_message functions. Affected file
4204 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4206 * Redefined the Private Message Payload to support private message
4207 keys and to support the new private message flags. Updated
4208 the protocol specs. Flags makes it possible to have for example
4209 CTCP style messages.
4211 * Added new type SilcPrivateMessagePayload and defined an API
4212 for it in the lib/silcclient/silcprivate.[ch].
4214 * Tested private message private keys successfully. Tested the
4215 private message key set, unset and list commands with the new
4218 * Redefined the Channel Message Payload to include the channel
4219 message flags (equal with private message flags) to support
4220 for example CTCP style messages.
4222 * Defined some of the message (for channel and private message)
4223 flags. Updated the protocol specs and added the flags to the
4224 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4226 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Added SilcKeyAgreementStatus type to the key agreement routines
4229 to indicate the current status and error if one occured.
4230 The status types are defined in the lib/silcclient/silcapi.h.
4232 * Added new local command KEY that is used to set and unset private
4233 keys for channels, set and unset private keys for private messages
4234 with remote clients and to send key agreement requests and
4235 negotiate the key agreement protocol with remote client. The
4236 key agreement is supported only to negotiate private message keys,
4237 it currently cannot be used to negotiate private keys for channels,
4238 as it is not convenient for that purpose.
4240 * Fixed a minor pending callback setting bug in the function
4241 silc_client_get_client_by_id_resolve, now the function works.
4242 Affected file lib/silcclient/idlist.c.
4244 * Added function silc_net_get_local_port to get local bound
4245 port by socket. Added to lib/silcutil/silcnet.[ch].
4247 * Added `sockets' and `sockets_count' fields to the SilcClient
4248 object. They hold the sockets of the listenning sockets in
4249 the client. Listenning sockets may be for example the key
4250 agreement server. Affected file lib/silcclient/client.[ch].
4251 Added functions the silc_client_add_socket and the
4252 silc_client_del_socket. They are exported to the application
4255 * Added ~./silc/clientkeys to support other client's public keys.
4257 * Renamed verify_server_key client operation to verify_public_key
4258 and added one argument to indicate the type of the connection
4259 (server, client etc.).
4261 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added silc_server_connection_auth_request to handle the
4264 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4265 silcd/packet_receive.[ch].
4267 * Added silc_server_send_connection_auth_request into the
4268 silcd/packet_send.c to send the connection auth request packet.
4270 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4273 * Fixed the public key authentication in responder side in the
4274 server. The `auth_data' pointer includes the SilcPublicKey
4275 not the path to the public key. Affected file silcd/protocol.c.
4277 * Implemented the public key authentication in the initiator side
4278 in the server. Affected file silcd/protocol.c.
4280 * Removed the [RedirectClient] config section from the server
4281 configuration. Is not needed and I don't want to implement it.
4283 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Cleaned up the CMODE command in the server. It now works
4286 correctly and supports all the modes defined in the protocol.
4287 Affected file is silcd/command.c.
4289 * Added `hmac_name' field to the SilcChannelEntry in the server
4290 to hold the default HMAC of the channel. It can be set when
4291 creating the channel (with JOIN command). Affected files
4294 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4295 type to indicate the change of the current cipher and hmac
4296 on the channel. Client can safely ignore the <cipher> argument
4297 (if it chooses to do so) since the CHANNEL_KEY packet will
4298 force the channel key change anyway. The <hmac> argument is
4299 important since the client is responsible of setting the new
4300 HMAC and the hmac key into use.
4302 * Fixed the CMODE command in the client library as well.
4304 * Tested CMODE command in router environment successfully.
4306 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Show the version of the remote client (or server) when connecting
4309 to the server. It is logged to the log file. Affected file
4310 is silcd/protocol.c.
4312 * Fixed the KILLED notify handling in the client library. The
4313 client must be removed from all channels when receiving the
4316 Also, do not remove the client entry when giving the KILL
4317 command but when the KILLED notify is received.
4319 * Removed silc_idlist_find_client_by_nickname from the server.
4320 Not needed anymore. Affected files silcd/idlist.[ch].
4322 * Implemented the CHANNEL_CHANGE notify type handling to the
4323 server. Affected file silcd/server.c.
4327 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Added silc_server_send_notify_invite to send the INVITE
4330 notify between routers.
4332 * Implemented the INVITE command correctly to the server.
4334 * Implemented the INVITE notify type handling in the server.
4336 * Implemented the INVITE command to the client library and on the
4339 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Added function silc_server_get_client_resolve to find the
4342 client entry by ID from all ID lists and then resolve it
4343 (using WHOIS) if it cannot be found. Affected file is
4346 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Implemented the BAN command to the client library.
4350 * The JOIN command in the server now checks the invite list
4353 * Changed the silc_command_reply_payload_encode_va and the
4354 silc_command_payload_encode_va to support that if argument is
4355 NULL it ignores and checks the next argument. Affected file
4356 lib/silccore/silccommand.c.
4358 * Added silc_server_send_notify_ban to send the BAN notify
4359 type between routers.
4361 * Chaned the silc_notify_payload_encode to support that if
4362 argument is NULL it ignores and checks the next argument.
4363 Affected file lib/silccore/silcnotify.c.
4365 * Tested ban lists in router environment successfully.
4367 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4369 * Implemented BAN command to the server, in silcd/command.[ch].
4371 * Removed the BAN and INVITE_LIST modes from the CMODE command
4374 * Added function silc_string_match to regex match two strings.
4375 Affected files lib/silcutil/silcutil.[ch].
4377 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Redefined parts of the SilcChannelEntry in the server to support
4380 the new ban and invite lists.
4382 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Redefined the INVITE command. The same command can be used to
4385 invite individuals to the channel but also to manage the invite
4386 list of the channel (to add to and remove from the invite list).
4387 Updated the protocol specs.
4389 * Added new command SILC_COMMAND_BAN that can be used to manage
4390 the ban list of the channel. Updated the protocol specs.
4392 * Removed the channel modes: the SILC_CMODE_BAN and the
4393 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4394 in the CMODE command. The equivalent features are now available
4395 using INVITE and BAN commands. Updated the protocol specs.
4397 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4398 in the network about change in the current ban list. The notify
4399 type is not used by the client.
4401 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4402 support the invite lists.
4404 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Added new function silc_string_regexify that converts string
4407 including wildcard characters into regex string that can
4408 be used by the GNU regex library. Added into the file
4409 lib/silcutil/silcutil.[ch].
4411 Added silc_string_regex_combine to combine to regex strings
4412 into one so that they can be used as one regex string by
4413 the GNU regex library. Added into the file
4414 lib/silcutil/silcutil.[ch].
4416 Added silc_string_regex_match to match two strings. It returns
4417 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4419 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Imported GNU regex to the soruce tree into lib/contrib.
4422 Fixed some compiler warning from the regex.c.
4424 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Fixed MOTD command in the server to work in router environment.
4428 * Fixed the MOTD command in the client library to support
4429 the server argument in the command.
4431 * Added `nickname_len' argument to the silc_idlist_add_client
4432 in the server, as the `nickname' argument may be binary data
4435 * Added silc_idlist_get_channels to return all channels from
4438 * Implemented LIST command to the server. Affected file is
4441 * Implemented the LIST command to the client library and on the
4444 * Added [<user count>] argument to the LIST command reply.
4445 With private channels the user count is not shown.
4447 * Updated TODO and README.
4449 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * The client entry's data.registered must be TRUE even with
4452 global client entry on global client list. The data.registered
4453 is used to check whether the client is anymore in the network,
4454 for example with WHOWAS command so it must be valid.
4456 * Fixed the WHOWAS command in the server. It now actually works
4457 in router environment. Added function into silcd/command_reply.c
4458 silc_server_command_reply_whowas_save.
4460 * Added silc_idlist_purge function to the silcd/idlist.c
4461 to periodically purge the ID Cache.
4463 * Fixed INFO command in the server. It works now in router
4464 environment. Added <server name> argument to the INFO command
4465 reply. Updated the protocol specs.
4467 * Fixed minor bug in silc_idcache_purge to not purge if the
4468 expire value is zero.
4470 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4471 they were buggy because of the WHOWAS information.
4473 * Fixed local command MSG to handle the async resolving of
4474 the remote client properly. It used to fail the first MSG.
4475 Affected file silc/local_command.c.
4477 * Added `data_len' field to SilcIDCache context.
4479 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Update TODO. Todo in commands in the server.
4483 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4486 used by routers as broadcast packet to inform other routers
4487 about the changed user mode.
4489 Implemented the notify handling in the server. Affected file is
4490 silcd/packet_receive.c. Added the function
4491 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4493 * Added new generic Channel Payload and deprecated the New Channel
4494 Payload. The New Channel Payload is now the generic Channel
4497 * Added new argument `mode' to the silc_server_send_new_channel
4498 as it is required in the Channel Payload now.
4500 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4501 and created a new and real SilChannelPayload to represent the
4502 new generic Channel Payload. Implemented the encode/decode
4503 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4505 * Added silc_server_get_client_channel_list to return the list
4506 of channels the client has joined for WHOIS command reply.
4507 Affected file silcd/server.[ch].
4509 * Implemented the channel list sending in the WHOIS command reply
4510 in server and in the client.
4512 Implemented the channel list displaying on the user interface
4513 as well. Affected file silc/client_ops.c.
4515 * Added silc_channel_payload_parse_list to parse list of Channel
4516 Payloads. It returns SilcDList list of SilcChannelPayloads.
4517 Client for example can use this function to parse the list of
4518 channels it receives in the WHOIS command reply. The caller
4519 must free the list by calling silc_channel_payload_list_free.
4520 Affected files lib/silccore/silcchannel.[ch].
4522 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Added one new argument <user mode> to the WHOIS command reply
4525 to return the mode of the user in SILC. Updated the protocol
4528 Implemented it to the server and client.
4530 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Fixed the mode printing on the user interface on joining.
4533 Affected file silc/client_ops.c.
4535 * Implemented the UMODE command and user modes in general to the
4536 client library and to the user interface.
4538 * Implemented the UMODE command to the server.
4540 * The server now sends UNKNOWN_COMMAND error status if client sends
4541 unknown command. Affected file silcd/command.c.
4543 * All server commands now handle the command identifier the right
4544 way when sending the command reply to the client. The client can
4545 use to identify the command replies with the identifier.
4547 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Added silc_server_get_client_route to resolve the route to
4550 the client indicated by the client ID. Affected file is
4553 * Added silc_server_relay_packet as general function to relay
4554 packet to arbitrary destination. This deprecates functions
4555 like _send_private_message_key, _relay_notify etc. Affected
4556 file is silcd/packet_send.[ch].
4558 Removed silc_server_send_key_agreement,
4559 silc_server_send_private_message_key and
4560 silc_server_packet_relay_notify functions from the file
4561 silcd/packet_send.[ch].
4565 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4566 server. Affected file silcd/packet_receive.[ch].
4568 * Implemented the KILL command to the client. Implemented the
4569 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4570 Affected files lib/silcclient/command[_reply].c and
4571 lib/silcclient/client_notify.c. Implemented the KILL notify
4572 printing in the user inteface.
4574 * Fixed a lot silc_parse_nick memory leaks from the client
4575 library in the file lib/silcclient/command.c.
4577 * Changed the silc_server_send_notify_on_channels's `sender'
4578 argument from SilcSocketConnection to SilcClientEntry to
4579 check the sender as entry and not as connection object and not
4580 to send to the client provided as argument. The affected file
4581 is silcd/packet_send.[ch].
4583 * The notify packets that are destined directly to the client used
4584 to not to be processed by the server. Now changed that and the
4585 server processes all notify packets. After relaying the packet
4586 to the client the notify packet is processed in the server.
4588 * The silc_server_free_client_data now checks whether there is
4589 pending outgoing traffic for the client and purges the data to
4590 the network before removing the client entry.
4592 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4595 an client is killed from the SILC Network. Updated the protocol
4598 Added new function silc_server_send_notify_killed to the
4599 silcd/packet_send.[ch].
4601 * Added function silc_server_packet_relay_notify to relay notify
4602 packets that are destined directly to a client. In this case
4603 the server does not process the notify packets but merely relays
4604 it to the client. Affected file silcd/packet_send.[ch].
4606 Added also silc_server_packet_process_relay_notify to check
4607 whereto relay the notify. Affected file is
4608 silcd/packet_receive.[ch].
4610 * Implemented the KILL command to the server.
4614 * Added the backup schema desgined last fall to the protocol
4615 specs for everyone to see. The specification is in the
4616 *-spec-xx.txt draft and the packet type definitions for the
4617 backup routers is in *-pp-xx.txt draft. Thusly, added also
4618 new packet type SILC_PACKET_CELL_ROUTERS.
4620 * A big security problem in the implementation discovered. The
4621 signoff of an client did not cause new channel key generation
4622 which it of course should've done. The channel keys must be
4623 always re-generated when client leaves (or signoffs) the channel.
4624 The silc_server_remove_from_channels funtion now handles
4625 the channel key re-generation.
4627 * Added `sender' argument to the silc_server_send_notify_on_channels
4628 to not to send the client provided as argument. Affected file
4629 silcd/packet_send.[ch].
4631 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Implemented OPER and SILCOPER commands into the server and
4636 * Added silc_auth_verify and silc_auth_verify_data to verify
4637 the authentication directly from the authentication payload.
4638 It supports verifying both passphrase and public key based
4639 authentication. Affected file lib/silccore/silcauth.[ch].
4641 * Added `hash' field to the SilcIDListData structure. It is the
4642 hash negotiated in the SKE protocol. Affected file is
4645 * Slight redesigning of the SilcAuthPayload handling routines.
4646 Do not send SilcPKCS but SilcPublicKey as argument.
4648 * Implemented the public key authentication support to the
4649 serverconfig. The public key is loaded from the provided path
4650 and saved as authentication data to void * pointer. Thus,
4651 changed the unsigned char *auth_data to void *auth_data;
4653 * Fixed SHUTDOWN command to send the reply before the server
4654 is shutdown. :) Affected file silcd/command.c.
4656 * Fixed fatal bug in CONNECT command. The hostname was invalid
4657 memory and server crashed. Affected file silcd/command.c.
4659 * Fixed fatal bug in CLOSE command. The server_entry became
4660 invalid but was referenced later in the command. Affected file
4663 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Fixed fatal bug in failure packet handling. Server ignored
4666 the failure and thus crashed when it came.
4670 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4673 that the command may be executed only once in (about) 2 seconds.
4674 The old SILC_CF_LAG flag is same but allows command bursts up
4675 to five before limiting.
4677 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4678 server code. Various commands now includes the CF_LAG_STRICT
4679 flag to disallow any kind of miss-use of the command.
4681 * Fixed the silc_buffer_unformat to not to allocate any data
4682 if the length of the data is zero. It used to allocate the
4683 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4685 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Changed the format of AdminConnection configuration section
4688 in the server. Added username of the admin to the format.
4689 Affected files silcd/serverconfig.[ch].
4691 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4692 to return admin configuration data by host, username and/or
4695 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * Implemented WHOWAS command to the server. Added the functions:
4699 silc_server_command_whowas_parse,
4700 silc_server_command_whowas_send_reply,
4701 silc_server_command_whowas_from_client and
4702 silc_server_command_whowas_from_server
4704 * Added <Client ID> argument to the WHOWAS command reply. Updated
4705 the protocol specs accordingly.
4707 * Implemented WHOWAS command and command_reply to the client
4710 Implemented the WHOWAS printing on the user interface.
4712 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4714 * Added new argument to the WHOWAS command reply, the real name.
4715 It is an optional argument. Updated the protocol specs.
4717 * Added SilcIDCacheDestructor callback that is registered when
4718 the SilcIDCache is allocated. The callback is called when
4719 an cache entry in the ID Cache expires, or is purged from the
4720 cache. Added into lib/silccore/idcache.[ch].
4722 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4723 to destruct the client entries when the cache entry expires.
4724 Other ID Cache's in server and in the client library ignores
4727 * If the ID Cache entry's `expire' field is zero then the entry
4728 never expires. Added boolean `expire' argument to the
4729 silc_idcache_add function in the lib/silccore/idcache.[ch].
4730 If it is TRUE the default expiry value is used.
4732 * Added silc_server_free_client_data_timeout that is registered
4733 when client disconnects. By default for 5 minutes we preserve
4734 the client entry for history - for WHOWAS command.
4736 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Added support to the server to enforce that commands are not
4739 executed more than once in 2 seconds. If server receives
4740 commands from client more frequently, timeout is registered
4741 to process the commands. Affected file silcd/command.c.
4742 Added new function silc_server_command_process_timeout.
4744 * Changed NICK_NOTIFY handling in client library to check that
4745 if the client's nickname was changed, so there is no need to
4746 resolve anything from the server.
4748 * Removed error printing from the WHOIS and IDENTIFY commands.
4749 If error occurs then it is ignored silently in the client library.
4750 The application, however, may map the received error to
4751 human readable error string. The application currently maps
4752 the NO_SUCH_NICKNAME error to string.
4754 * Made the command status message public to the application. Moved
4755 them from lib/silcclient/command_reply.c to
4756 lib/silcclient/command_reply.h. The application can map the
4757 received command status to the string with the
4758 silc_client_command_status_message function.
4760 * Added check to the server to check that client's ID is same
4761 as the Source ID in the packet the client sent. They must
4764 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Added dist-bzip hook to the Makefile.am to make bzip2
4767 compressed distributions.
4769 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Server now enforces the maximum length for the nickname and
4772 the channel as protocol specification dictates. 128 bytes for
4773 nickname and 256 bytes for channel name.
4775 * Moved the WHOIS printing to the application. The client libary
4776 does not print out the WHOIS information anymore, the application
4777 must do it. Renamed silc_client_command_reply_whois_print to
4778 the silc_client_command_reply_whois_save.
4780 The client's idle time is also sent to the application now, and
4781 the idle is shown on screen.
4783 * Added silc_client_command_reply_identify_save to save the
4784 received IDENTIFY entries.
4786 * Do not check for channel private keys in message sending and
4787 reception if the channel does not have the PRIVKEY mode set.
4788 Affected file lib/silclient/client_channel.c.
4790 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4793 just surfaced after chaning the JOIN procedure.
4795 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added silc_client_get_clients_by_list to get client entries
4798 from Client ID list, that is returned for example by JOIN
4799 and USERS command replies. The application should use this
4800 function for example when JOIN command reply is received to
4801 resolve the clients already on the channel (library does not
4802 do that anymore as USERS command reply is not used in the JOIN
4803 procedure anymore). Affected files lib/silcclient/silcapi.h and
4804 lib/silcclient/idlist.c.
4806 * JOIN command reply and USERS command reply returns now SilcBuffer
4807 pointers instead of unsigned char pointers when returning
4808 the client list and mode list.
4810 * Added <Client ID> argument to the JOIN command reply, mainly
4811 for the server to identify for which client the command was
4812 originally sent. Updated protocol specs accordingly.
4814 * Added SilcDlist private_key pointer to the SilcChannelEntry
4815 in the client to support the channel private keys. Affected
4816 file is lib/silcclient/idlist.h.
4818 * Added SilcChannelPrivateKey argument to the function
4819 silc_client_send_channel_message so that application can choose
4820 to use specific private ke if it wants to. If it is not provided,
4821 the normal channel key is used, unless private keys are set.
4822 In this case the first (key that was added first) is used
4823 as the encryption key.
4825 * Implemented the support for channel private key handling.
4826 Implemented the following functions:
4828 silc_client_add_channel_private_key,
4829 silc_client_del_channel_private_keys,
4830 silc_client_del_channel_private_key,
4831 silc_client_list_channel_private_keys and
4832 silc_client_free_channel_private_keys
4834 Affected file lib/silcclient/client_channel.c.
4836 * Added the support for the private keys in the channel message
4837 sending and encryption and in the message reception and
4838 decryption. Affected funtions are
4839 silc_client_send_channel_message and silc_client_channel_message.
4841 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Added SKE's key verify callback to the client library's
4844 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4846 * Removed the statement that server (or router) must send USERS
4847 command reply when joining to the channel so that the client
4848 knows who are on the channel. Instead, the client list and
4849 client's mode list is now sent in the JOIN command reply to the
4850 client who joined channel. This is better solution.
4852 * Added function silc_server_get_users_on_channel and function
4853 silc_server_save_users_on_channel to the silcd/server.[ch].
4855 * Removed function silc_server_command_send_users from the
4858 * Do not show topic on the client library anymore. The topic is
4859 sent in the command reply notify to the application and the
4860 application must show the topic now.
4862 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added client searching by nickname hash into the IDENTIFY and
4865 WHOIS commands in the server as they were clearly missing from
4866 them. Affected file is silcd/command.c.
4868 * Fixed a bug in private message receiving in the client library.
4869 The remote ID was freed and it wasn't supposed, now it is
4872 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Minor fix to the channel payload; allocate the data area, as it
4875 needs to be of specific length.
4877 * If the key agreement port is zero then the operating
4878 system will define the bound port. Affected files are
4879 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4881 * Added new function silc_channel_payload_decrypt into the file
4882 lib/silccore/silcchannel.[ch].
4884 * Moved the channel message etc, check from silc_packet_decrypt
4885 to applications. The library calls now a generic
4886 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4887 when the packet is either normal or special. This was done to
4888 allow more wide range of checking that was not allowed when
4889 the code was in library. Now applications can do virtually any
4890 checks to the packet and return to the library the decision how
4891 the packet should be processed. Affected files are
4892 lib/silccore/silcpacket.[ch].
4894 Added silc_server_packet_decrypt_check to the server and
4895 silc_client_packet_decrypt_check to the client library.
4897 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4898 to send with specified source and destination information.
4900 * Channel message delivery between routers was broken after the
4901 channel key distribution was fixed earlier. The channel key
4902 was used be to distributed to other routers as well which is not
4903 allowed by the protocol. Now this is fixed and channel keys
4904 really are cell specific and the channel message delivery between
4905 routers comply with the protocol specification.
4907 * Fixed various commands in server to check also the global list
4908 for the channel entry and not just the local list. The affected
4909 file silcd/command.c.
4911 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Added assert()s to buffer formatting and unformatting routines
4914 to assert (if --enable-debug) when error occurs. Affected
4915 file: lib/silcutil/silcbuffmt.c.
4917 * Changed to auto-reconnect to check whether the remote host is
4918 router and register the re-connect timeout if it is. It used
4919 to check that whether we are normal server, but router must do
4920 auto-reconnect with another router as well. Affected file
4923 * Removed the [<key len>] option from CMODE command as the cipher
4924 name decides the key length, nowadays. See the defined ciphers
4925 from the protocol specification.
4927 * Added [<hmac>] option to the CMODE command to define the HMAC
4928 for the channel. Added SILC_CMODE_HMAC channel mode.
4930 * Added [<hmac>] option for the JOIN command so that user can
4931 select which HMAC is used to compute the MACs of the channel
4934 * Added Hmac field to the Channel Message Payload. The integrity
4935 of plaintext channel messages are now protected by computing
4936 MAC of the message and attaching the MAC to the payload. The
4937 MAC is encrypted. Now, it is clear that this causes some
4938 overhead to the size of the packet but rationale for this is that
4939 now the receiver can verify whether the channel message decrypted
4940 correctly and also when private keys are set for the channel the
4941 receiver can decrypt the packet with several keys and check from
4942 the MAC which key decrypted the message correctly.
4944 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4945 lib/silccrypt/silccipher.[ch].
4947 * Added silc_hash_len to return the digest length into the
4948 lib/silcrypt/silchash.[ch].
4950 * Rewrote parts of Silc Channel Payload interface in the
4951 lib/silccore/silcchannel.[ch]. The encode function now also
4952 encrypts the packet and parse function decrypts it.
4954 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Fixed a minor formatting bug in the SKE's key material processing.
4957 It actually might have processed the keys wrong way resulting
4960 * Redefined the mandatory HMAC algorithms and added new algorithms.
4961 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4962 and hmac-md5 truncated to 96 bits. The mandatory is now
4963 hmac-sha1-96. Rest are optional (including the one that used
4964 to be mandatory). Rationale for this is that the truncated HMAC
4965 length is sufficient from security point of view and can actually
4966 make the attack against the HMAC harder. Also, the truncated
4967 HMAC causes less overhead to the packets. See the RFC2104 for
4970 * Added new [hmac] configuration section. The SKE used to use
4971 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4972 is of course wrong. The official names that must be proposed in
4973 the SKE are the ones defined in the protocol specification
4974 (hmac-sha1-96 for example). The user can configure any hmac
4975 using any hash function configured in the [hash] section. At
4976 least, the mandatory must be configured.
4978 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4980 * Added HMAC list to the SKE proposal list. It has now both
4981 hash algorithm list and HMAC list. This makes the protocol
4982 incompatible with previous versions. The SKE now seems to work
4983 the way it is supposed to work, for the first time actually.
4985 * Defined plain Hash algorithms to the protocol specification.
4988 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Implemented support for key agreement packets into the server.
4991 Added functions silc_server_key_agreement and
4992 silc_server_send_key_agreement. Other than these functions,
4993 server has nothing to do with this packet.
4995 * Added support for private message key packets into the server.
4996 Added functions silc_server_private_message_key and
4997 silc_server_send_private_message_key.
5001 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5002 called in the protocol's final callback instead in the END
5003 protocol state. This makes a little more sense and in the same
5004 time in client we can use the same protocol routines for normal
5005 key exchange and to key agreement packet handling as well.
5007 * Added to both client's and server's KE protocol context the
5008 SilcSKEKeyMaterial pointer to save the key material. We will
5009 bring the key material to the protocol's final callback by doing
5010 this. The final callback must free the key material.
5012 * Added SKE's packet_send callback into client's KE protocol
5013 context so that the caller can choose what packet sending function
5014 is used. This way we can use different packet sending when
5015 doing normal SKE when doing key agreement packet handling (in
5016 the key agreement packet handling we do not want to encrypt
5019 * Implemented the responder side of the key agreement routines
5020 in the client. The client can now bind to specified port and
5021 accept incoming key negotiation. The key material is passed
5022 to the application after the protocol is over.
5024 * Implemented the processing of incoming Key Agreement packet
5025 in the client. Added function silc_client_key_agreement to
5028 * Implemented the intiator side of the key agreement routines
5029 in the client. The client can now initiate key agreement with
5030 another remote client. The key material is passed to the
5031 application after the protocol is over.
5033 * Created client_keyagr.c to include all the key agreement
5036 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5037 SILC_TASK_CALLBACK except that it is not static.
5039 * Created client_notify.c and moved the Notify packet handling
5040 from the client.[ch] into that file.
5042 * Created client_prvmsg.c and moved all private message and
5043 private message key routines from the client.[ch] into that file.
5045 * Create client_channel.c and moved all channel message and
5046 channel private key routines from the client.[ch] into that file.
5048 * Changed silc_client_get_client_by_id_resolve to resolve with
5049 WHOIS command instead of IDENTIFY command, in the file
5050 lib/silclient/idlist.c.
5052 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Implemented the SKE's responder side to the Client library.
5056 * When FAILURE is received to the protocol do not trust it
5057 blindly. Register a timeout to wait whether the remote closes
5058 the connection as it should do it, only after that process the
5059 actual failure. This was changed to both client and server.
5061 * Added client_internal.h to include some of the structures
5062 there instead of client.h in lib/silcclient/.
5064 * Added function silc_task_unregister_by_callback to unregister
5065 timeouts by the callback function.
5067 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Some "Incomplete WHOIS info" errors has been appearing on the
5070 log files. Took away the entry->userinfo check from WHOIS
5071 reply sending. The entry->userinfo is now " " if client did not
5072 provide one. I thought this was fixed earlier but something
5073 is wrong still. Let's see if the error still appears.
5075 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Fixed a minor bug in the login when the channel key is
5078 re-generated in the server. It used to generate the key in
5079 wrong order and thus caused problems in the channel traffic.
5081 * Fixed a minor bug in channel key distsribution after
5082 KICK command. The key was not sent to the router even though
5085 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added silc_ske_process_key_material_data as generic routine
5088 to process any key material as the SILC protocol dictates. The
5089 function is used by the actual SKE library but can be used by
5090 applications as well. This relates to the private message keys
5091 and the channel private keys since they must be processed the
5092 same way the normal SILC session keys. The protocol dictates
5093 this. Affected files: lib/silcske/silcske.[ch].
5095 Added also silc_ske_free_key_material to free the
5096 SilcSKEKeyMaterial structure.
5098 * Defined silc_cipher_set_key function to set the key for
5099 cipher without using the object's method function. The affected
5100 files: lib/silccrypt/silccipher.[ch].
5102 * Implemented silc silc_client_add_private_message_key,
5103 silc_client_add_private_message_key_ske,
5104 silc_client_del_private_message_key,
5105 silc_client_list_private_message_keys and
5106 silc_client_free_private_message_keys functions in the
5109 Added functions silc_client_send_private_message_key to send
5110 the Private Message Key payload and silc_client_private_message_key
5111 to handle incoming Private Message Key payload.
5113 * Added Cipher field to the Private Message Key payload to set
5114 the cipher to be used. If ignored, the default cipher defined
5115 in the SILC protocol (aes-256-cbc) is used.
5117 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Removed lib/silcclient/ops.h file.
5121 Redefined parts of the SILC Client Library API. Created new
5122 file silcapi.h that deprecates the ops.h file and defines the
5123 published Client Library API. Defined also private message key
5124 API and channel private key API into the file.
5126 This is the file that the application must include from the
5127 SILC Client Library. Other files need not be included by
5128 the application anymore.
5130 * Added new key_agreement client operation callback and also
5131 defined the Key Agreement library API for the application.
5133 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5136 is used by clients to request key negotiation between another
5137 client in the SILC network. If the negotiation is started it
5138 is performed using the SKE protocol. The result of the
5139 negotiation, the secret key material, can be used for example
5140 as private message key.
5142 Implemented the Key Agreement payload into the files
5143 lib/silccore/silauth.[ch].
5145 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Redefined ciphers for the SILC protocol. Added some new ciphers
5148 and defined the key lengths for the algorithms. Changed the
5149 code accordingly. The default key length is now 256 bits.
5151 * Fixed SKE key distribution function silc_ske_process_key_material
5152 when the key length is more than 128 bits. The default key
5153 length in SILC is now 256 bits.
5155 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5156 to indicate unsupported algorithm.
5158 * Renamed rijndael.c to aes.c and all functions as well.
5160 * Fixed a long standing channel key setting bug in client library.
5161 Weird that it has never surfaced before.
5163 * Fixed bug in channel deletion. If the entire channel is removed
5164 then it must also delete the references of the channel entry
5165 from the client's channel list as the client's channel entry and
5166 the channel's client entry share same memory.
5168 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Implemented CONNECT and SHUTDOWN commands in the client.
5172 * Implemented CLOSE command to the client.
5174 * Added the function silc_idlist_find_server_by_name into the
5175 files silcd/idlist.[ch].
5177 Added the function silc_idlist_find_server_by_conn into the
5178 files silcd/idlist.[ch].
5180 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * DIE command was renamed to SHUTDOWN. Updated the both code
5185 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5186 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5188 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5191 * Added function silc_server_create_connection function to create
5192 connection to remote router. My server implementation actually
5193 does not allow router to connect to normal server (it expects
5194 that normal server always initiates the connection to the router)
5195 so the CONNECT command is only good for connecting to another
5198 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5201 or some other client was kicked from the channel.
5203 Implemented the handling of the notify type to both client
5206 Implemented silc_server_send_notify_kicked to send the KICKED
5207 notify. It is used to send it to the server's primary router.
5209 * Implemented the KICK command into server and client.
5211 * Added `query' argument to the silc_idlist_get_client function
5212 to indicate whether to query the client from server or not if
5215 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5216 to indicate that the client is not channel founder.
5220 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5222 * Removed the rng context from SilcPacketContext structure and
5223 changed that the packet routine uses the Global RNG API.
5225 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Added support for quit message that client can "leave" on the
5228 channel when it quits the SILC. It is ditributed inside the
5229 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5231 Added silc_server_free_client_data that will take the
5232 signoff message as argument.
5234 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5236 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Updated parts of the protocol specification to keep it up
5241 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5244 payloads in one packet.
5246 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5247 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5248 use now the new List flag.
5250 * Also deprecated the following packet types: REPLACE_ID,
5251 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5253 * Added list support for Notify packet in server.
5255 * Added silc_server_send_notify_channel_change to send the
5256 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5257 the silc_server_send_replace_id.
5259 * Added silc_server_send_notify_nick_change to send the
5260 NICK_CHANGE notify type. Deprecates the function
5261 silc_server_send_replace_id.
5263 * Added silc_server_send_notify_join to send the JOIN notify type.
5264 Deprecates the function silc_server_send_new_channel_user.
5266 * Added silc_server_send_notify_leave to send LEAVE notify type.
5267 Deprecates the function silc_server_send_remove_channel_user.
5269 * Added silc_server_send_notify_cmode and
5270 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5271 types. Deprecates the silc_server_send_set_mode function.
5273 * Added SERVER_SIGNOFF notify type to indicate that server has
5274 quit. This means that all clients on the channel from that
5275 server will drop. This can be also used when netsplit happens.
5277 Deprecated REMOVE_ID packet type since it is not needed anymore
5280 Added silc_server_send_notify_server_signoff to send the
5281 SERVER_SIGNOFF notify type. Deprecates the function
5282 silc_server_send_remove_id.
5284 Added also silc_server_send_notify_signoff to send the
5285 SIGNOFF notify type.
5287 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5288 SILC protocol from this day on. Changed the protocol
5289 specification as well.
5291 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5292 notify type. It is used between routers to notify about
5293 topic changes on a channel.
5295 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5298 * Partly updated the protocol specification to comply with the
5299 changes now made. It is still though a bit outdated.
5301 * The JOIN notify type now takes one extra argument <Channel ID>.
5302 The packet used to be destined to the channel but now the
5303 JOIN type may be sent as list thus it is impossible to
5304 destine it to any specific channel. By adding this argument
5305 it is again possible.
5307 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Added CREDITS file. The CHANGES and CREDITS file will appear
5310 in the distribution as well.
5312 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5315 types in the server's silcd/packet_receive.c.
5317 * Implemented CMODE and CUMODE to work in router environment.
5319 * Fixed minor encoding and decoding buglet from the
5320 lib/silccore/silcmode.c.
5322 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5325 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5327 * Changed all SilcConfigServer* and silc_config_server* to
5328 SilcServerConfig* and silc_server_config*, respectively.
5331 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Associated the ID (client or server ID) to the Authentication
5334 Payload to avoid any possibility of forging. Updated the
5335 protocol specification and the code accordingly.
5337 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * The RSA key length is now save to the RsaKey context in the
5340 key generation process in lib/silccrypt/rsa.c. The key length
5341 is now used to figure out the maximum size of the block allowed
5342 to be encrypted/signed.
5344 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5345 is equivalent to the silc_mp_mp2bin but does not allocate any
5348 * Changed silc_mp_mp2bin API to take length argument. If it is
5349 non-zero then the buffer is allocated that large. If zero, then
5350 the size is approximated using silc_mp_sizeinbase, which however
5353 * Created Global RNG API which is global RNG that application can
5354 initialize. After initializing, any routine anywhere in the
5355 code (including library) can use RNG without allocating a new
5356 RNG object. This was done to allow this sort of use of the
5357 RNG in code that has no chance to allocate RNG object. All
5358 applications currently allocate this and many routines in the
5359 library use this. Affected file lib/silccrypt/silcrng.[ch].
5361 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5362 it to use the Global RNG API.
5364 * Defined Authentication Payload into protocol specification that
5365 is used during SILC session to authenticate entities. It is
5366 used for example by client to authenticate itself to the server
5367 to obtain server operator privileges.
5369 Implemented this payload into the lib/silccore/silcauth.[ch].
5370 Implemented also routines for public key based authentication
5371 as the new protocol specification dictates.
5373 Moved definitions of different authentication methods from
5374 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5376 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5377 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5378 silc_pkcs_verify_with_hash functions into the file
5379 lib/silccrypt/silcpkcs.[ch].
5381 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * The client entry's userinfo pointer must be always valid.
5384 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5385 will fail since it requires the userinfo. Now, the userinfo
5386 is allocated as "" if actual userinfo does not exist. Actually,
5387 it must exist and it is totally Ok to drop client connections
5388 that does not announce the userinfo. However, we will make
5389 this workaround for now.
5391 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5392 to return the remote port by socket.
5394 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5397 SILC_SERVER_PENDING_EXEC and added an new macro
5398 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5399 data or when error occurs while processing the pending command.
5401 Added new argument `destructor' into silc_server_command_pending
5402 and to the SilcServerCommandPending object. This destructor is
5403 now called after calling the pending callback or if error occurs
5404 immediately. If error occurs the actual pending callback won't
5405 be called at all - only the destructor. The destructor may be
5406 NULL if destructor is not needed.
5408 All this applies for client library code as well. Similar
5409 changes were made there as well for the pending commands.
5411 In the client, the application must now allocate the
5412 SilcClientCommandContext with the silc_client_command_alloc
5415 * Added reference counter to the SilcServerCommandContext. Added
5416 function silc_server_command_alloc and silc_server_command_dup
5419 Same type of functions added to the client library for the same
5422 * Removed the cmd_ident from IDListData away since it is now
5423 global for all connections. It is the command identifier used
5424 in command sending and with pending commands. The affected file
5427 * Added reference counter to the SilcSocketConnection objecet to
5428 indicate the usage count of the object. The object won't be
5429 freed untill the reference counter hits zero. Currently only
5430 server uses this, and client ignores it. The client must be
5431 set to use this too later. The affected files are
5432 lib/silccore/silcsockconn.[ch]. Added also the function
5433 silc_socket_dup to increase the reference counter.
5435 This was mainly added because it is possible that the socket
5436 is removed underneath of pending command or other async
5437 operation. Now it won't be free'd and proper DISCONNECTING
5438 flags, etc. can be set to avoid sending data to connection that
5439 is not valid anymore.
5441 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5442 the connection. After that it sets SILC_SET_DISCONNECTED.
5443 It is, however, possible that the socket data is not still freed.
5444 The silc_server_packet_process now checks that data is not
5445 read or written to connection that is DISCONNECTED. The socket
5446 get's freed when the reference counter hits zero.
5448 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Changed the client operation API: channel_message operation's
5451 `sender' is now the client entry of the sender, not the nickname
5452 and the `channel' is the channel entry, not the channel name.
5454 In the private_message operation the `sender' is now also the
5455 client entry of the sender not the nickname.
5457 Affected file is lib/silcclient/ops.h and all applications
5458 using the client operations.
5460 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Moved the calling of ops->connect() from connect_to_server_final
5463 into receive_new_id functin since that is the point when the
5464 client is actually allowed to send traffic to network. The
5465 affected file is lib/silcclient/client.c.
5467 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5470 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5471 (if needs broadcasting) instead of broadcasting the packets one
5472 by one which would make a burst in the network traffic.
5474 * Added `broadcast' argument to the functions in silcd/server.[ch]
5475 silc_server_create_new_channel[_with_id] to indicate whether
5476 to send New Channel packet to primary router.
5478 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Added new function into the silcd/server.[ch] files:
5481 silc_server_create_new_channel_with_id to create new channel with
5482 already existing Channel ID.
5484 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5485 lib/silccore/silcpacket.h. This packet is used t send list of
5486 Set Mode payloads inside one packet. Server uses this to set
5487 the modes for the channels and clients on those channels, that it
5488 announced to the router when it connected to it. The protocol
5489 specification has been updated accordingly.
5491 * The silc_server_new_channel did not handle the packet coming
5492 from normal server as it normally does not send that. However,
5493 when it announces its channels it does send it. Implemented
5494 the support for that.
5496 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5497 into the file lib/silccore/id.h.
5499 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Fixed memory leaks in the functions silc_idlist_del_client,
5502 silc_idlist_del_channel and silc_idlist_del_server in the file
5503 silcd/idlist.c. All of those leaked like a sieve.
5505 * Fixed some small memory leaks in the client's function
5506 silc_client_notify_by_server.
5508 * Added functions into silcd/server.c: silc_server_announce_clients,
5509 silc_server_announce_channels and silc_server_announce_server.
5510 These functions are used by normal and router server to announce
5511 to its primary router about clients, channels and servers (when
5512 router) that we own. This is done after we've connected to the
5515 These functions effectively implements the following packet types:
5516 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5517 and SILC_PACKET_NEW_ID_LIST.
5519 * Added new functions into the silcd/packet_receive.[ch]:
5520 silc_server_new_id_list, silc_server_new_channel_list and
5521 silc_server_new_channel_user_list to handle the incoming
5522 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5524 * Added support of changing Channel ID in the function
5525 silc_server_replace_id. If the server that announces a channel
5526 to the router already exists in the router (with same name but
5527 with different Channel ID), router is responsible to send
5528 Replace ID packet to the server and force the server to change
5529 the Channel ID to the one router has.
5531 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5532 client that the Channel ID has been changed by the router. The
5533 normal server sends this to the client. Client must start using
5534 the new Channel ID as the channel's ID.
5536 Implemented handling of this new type into lib/silcclient/client.c
5537 into the function silc_client_notify_by_server.
5539 * Added new function silc_idlist_replace_channel_id into the files
5540 silcd/idlist.[ch] to replace the Channel ID.
5542 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Call silc_server_command_identify_check always when processing
5545 the IDENTIFY command in silcd/command.c
5547 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5550 send keepalive packets. The packet can be sent by clients,
5551 servers and routers.
5553 Added function silc_socket_set_heartbeat into the file
5554 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5555 If not set, the heartbeat is not performed. The actual
5556 heartbeat is implemented in the low level socket connection
5557 library. However, application is responsible of actually
5560 Added silc_server_send_heartbeat to send the actual heartbeat
5561 packet into silcd/packet_send.[ch]. Server now performs
5562 keepalive with all connections.
5564 * Added silc_task_get_first function into lib/silcutil/silctask.c
5565 to return the timeout task with shortest timeout. There was a bug
5566 in task unregistration that caused problems. TODO has been
5567 updated to include that task system must be rewritten.
5569 * The client library will now resolve the client information when
5570 receiving JOIN notify from server for client that we know but
5571 have incomplete information.
5573 * Rewrote parts of silc_server_remove_from_channels and
5574 silc_server_remove_from_one_channel as they did not remove the
5575 channel in some circumstances even though they should've.
5577 * Encryption problem encountered in server:
5579 The LEAVE command used to send the Channel Key packet to the
5580 router immediately after generating it. However, the code
5581 had earlier sent Remove Channel user packet but not immediately,
5582 ie. it was put to queue. The order of packets in the router
5583 was that Channel Key packet was first and Remove Channel User
5584 packet was second, even though they were encrypted in the
5585 reverse order. For this reason, MAC check failed. Now, this
5586 is fixed by not sending the Channel Key packet immediately but
5587 putting it to queue. However, this is more fundamental problem:
5588 packets that are in queue should actually not be encrypted
5589 because packets that are sent immediately gets encrypted
5590 actually with wrong IV (and thus MAC check fails). So, packets
5591 that are in queue should be encrypted when they are sent to
5592 the wire and not when they put to the queue.
5594 However, the problem is that the current system has not been
5595 designed to work that way. Instead, the packet is encrypted
5596 as soon as possible and left to the queue. The queue is then
5597 just purged into wire. There won't be any fixes for this
5598 any time soon. So, the current semantic for packet sending
5601 o If you send packet to remote host and do not force the send
5602 (the packet will be in queue) then all subsequent packets to the
5603 same remote host must also be put to the queue. Only after the
5604 queue has been purged is it safe again to force the packet
5607 o If you send all packets immediately then it safe to send
5608 any of subsequent packets through the queue, however, after
5609 the first packet is put to queue then any subsequent packets
5610 must also be put to the queue.
5612 Follow these rules and everything works fine.
5614 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added new function silc_server_remove_clients_by_server to
5617 remove all client entries from ID list when the server connection
5618 is lost. In this case it is also important to invalidate all
5619 client entires as they hold the invalid server entry. This
5620 fixes fatal bug when server has lost connection and will reconnect
5623 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Made some sanity checks to silc_server_daemonise like to check
5626 whether the requested user and group actually exists.
5628 * Added sanity check to SKE's silc_ske_responder_finish to check
5629 that the public and private key actually is valid.
5631 * Invalidate the client's nickname when receiving Replace ID
5632 packet and the Client ID is being replaced. This means that the
5633 server will query the nickname if someone needs it (client)
5636 * Sort the ID Cache in client library when the ID Cache data
5637 has changed (needs sorting).
5639 * Do not allow for SILC client to create several connections to
5640 several servers. The client does not support windows right now
5641 and generating multiple connections causes weird behaviour.
5643 Irssi-silc client does support windows and can handle several
5644 connections without problems, see: www.irssi.org and SILC plugin.
5646 * Fixed some places where client was added to the IDList. The
5647 rule of thumb is following (in order to get everything right):
5648 If the client is directly connected local client then the
5649 `connection' argument must be set and `router' argument must be
5650 NULL to silc_idlist_add_client function. If the client is not
5651 directly connected client then the `router' argument must
5652 bet set and the `connection' argument must be NULL to the
5653 silc_idlist_add_client function.
5655 * The funtion silc_server_packet_send_local_channel actually did
5656 not check whether the client was locally connected or not. It
5657 does that now. Fixed a bug related to LEAVE command.
5659 * Fixed Remove Channel User payload parsing bug in server's
5660 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5662 * The server's silc_server_save_channel_key now checks also the
5663 global ID list for the channel as it might not be in the local
5664 list. Fixed a bug related to LEAVE command.
5666 * Is this the end of the [<unknown>] buglet that has been lurking
5667 around for a long time? A little for loop fix in server's
5668 silc_server_command_whois_parse that is used by both IDENTIFY
5669 and WHOIS command. At least, this was a clear bug and a cause
5670 of one type of [<unknown>] buglet.
5672 * WHOIS and IDENTIFY commands call the function
5673 silc_server_command_[whois/identify]_check function even if
5674 we are not router server.
5676 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Added --with-gmp configuration option. If set the GMP
5679 is always compiled in the SILC source tree. If not set then
5680 it is checked whether the system has the GMP3 installed. If
5681 it has then the GMP won't be compiled (the system's headers
5682 and library is used), if it doesn't have it then the GMP is
5683 compiled in the SILC source tree.
5685 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Changed RSA private exponent generation to what PKCS #1
5688 suggests. We try to find the smallest possible d by doing
5689 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5690 not security fix but optimization.
5692 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Added new config entry [Identity] to fork the server and run
5695 it as specific user and group. A patch from Bostik.
5697 * Imported Dotconf configuration library into lib/dotconf.
5698 This will be used to create the SILC configuration files later.
5699 It will appear in the distsribution after this commit.
5701 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * A big code auditing weekend happening. Auditing code for
5704 obvious mistakes, bugs and errors. Also, removing any code
5707 Removed files for being obsolete:
5709 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5710 inline in the file lib/silcutil/silcbuffer.h)
5712 o lib/silcutil/silcbufutil.c (the header has inline versions)
5714 Changed code to fix possible error conditions:
5716 o The buffer formatting routines now check that the destination
5717 buffer really has enough space to add the data. This applies for
5718 both buffer formatting and unformatting
5719 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5720 unformatting was changed to accomodate following rules:
5721 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5722 sent to the function while XXX_*STRING will not allocate or copy
5723 the data into the buffer. Instead it sets the pointer from the
5724 buffer into the pointer sent as argument (XXX_*STRING used to
5725 require that the pointer must be allocated already). This change
5726 makes this whole thing a bit more consistent and more optimized
5727 (note that the data returned in the unformatting with XXX_*STRING
5728 must not be freed now). The routines return now -1 on error.
5730 o Tried to find all code that use buffer_format and buffer_unformat
5731 and added return value checking to prevent formatting and
5732 especially unformatting errors and possible subsequent fatal
5735 o Changed ske->x and ske->KEY to mallocated pointers in
5736 lib/silcske/silcske.h. Fixed possible data and memory leak.
5738 o Added return value checking to all *_parse* functions. Fixed
5739 many memory leaks as well.
5741 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5742 so that buffer overflows would not happen. All code now also
5743 checks the return value as it can fail.
5745 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Added reconnection support to server if the normal server looses
5748 its connection to the router (for example if router is rebooted).
5749 The server performs normal reconnection strategy implemented
5750 to the server. Affected file silcd/server.c.
5752 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Added new packet type SILC_PACKET_SET_MODE that is used to
5755 distribute the information about changed modes (for clients,
5756 channels and clients channel modes) to all routers in the
5757 network. Updated the protocol specification accordingly.
5759 Added functions into silcd/packet_send.c and
5760 silcd/packet_receive.c: silc_server_send_set_mode,
5761 silc_server_set_mode.
5763 Added new files silcmode.[ch] into lib/silccore that implements
5764 the encoding and decoding of Set Mode Payload. Added new type
5765 SilcSetModePayload. Moved the definitions of different modes
5766 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5768 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Oops, a little mistake in server's connection authentication
5771 protocol. The protocol is not ended with FAILURE but with
5772 SUCCESS if the authentication is Ok. :) Affected file is
5775 * Implemented NICK_CHANGE notify handling in server in the file
5776 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5777 the local clients on the channel. After the changing nickname
5778 in router environment snhould work and the [<unknown>] nickname
5779 should appear no more.
5781 The silc_server_replace_id function that receives the Replace ID
5782 payload now sends the NICK_CHANGE notify type also in the file
5783 silcd/packet_receive.c
5785 * Changed WHOIS and IDENTIFY command to support the maximum amount
5786 of arguments defined in protocol specs (3328 arguments). This
5787 fixed a bug that caused problems when there were more than three
5790 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added extra parameter, command identifier, to the
5793 silc_client_send_command so that explicit command identifier
5796 Changed that ID list routines uses specific command identifier
5797 when sending WHOIS/IDENTIFY requests to the server so that they
5798 can be identified when the reply comes back.
5800 Affected files lib/silcclient/command.[ch],
5801 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5803 * Added `sender' argument to silc_server_packet_send_to_channel
5804 to indicaet the sender who originally sent the packet to us
5805 that we are now re-sending. Ignored if NULL. Affected file
5806 silcd/packet_send.[ch].
5808 * Added some server statistics support in silcd/server_internal.h
5809 SilcServerStatistics structure and around the server code. Also
5810 send some nice statistics information when client is connecting
5813 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Fixed channel ID decoding in server's JOIN command reply in
5816 silcd/command_reply.c
5818 * Fixed braodcasting of replace ID payload to not to send it if
5819 we are standalone server in silcd/packet_receive.c.
5821 * Fixed all channel message sending routines to not to send
5822 packets to clients that has router set, since they are routed
5823 separately in the same function earlier. Affects file
5824 silcd/packet_send.c and all channel packet sending functions.
5826 * In USERS reply, res_argv[i] are not allocated, the table
5827 is allocated. Thus changed that free the table, not its
5830 * In server's whois_check and identify_check if the client is
5831 locally connected do not send any WHOIS commands - they are not
5834 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Fixed some minor bugs in client when sending WHOIS command. The
5837 arguments was in wrong order.
5839 * Removed statis function add_to_channel from server in
5840 silcd/command.c that was previously used with the joining but
5843 * Tested USERS command in router environment successfully with two
5844 routers, two servers and two clients.
5846 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5848 * Reorganized the USERS command and command reply in client library
5849 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5850 When the command is given by user we register a pending command
5851 callback that will reprocess the command after the reply has been
5852 received from the server. When reprocessing the packet we then
5853 display the information. Thus, the USERS information is displayed
5854 now in the command callback instead of in the command reply
5855 callback. The processing of the command is same as previously
5856 when server has sent the command reply in the JOINing process.
5858 * Added to USERS command in silcd/command_reply.c to join the client,
5859 we didn't use to know about, to the channel after we've created
5860 a client entry for it. Also, for clienet we did know already still
5861 check whether it is on the channel or not and add it if not.
5863 * Removed silc_server_command_join_notify as the function and its
5866 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Changed the client's pending command handling to the same as the
5869 server's pending command handling. It is also now possible to
5870 execute command reply functions from other command reply
5871 function as the function callbacks for commands and command
5872 replies are one and same. The pending commands are not static
5873 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5874 in client connection context. Thus, pending commands are server
5875 connection specific as it is convenient.
5877 Changed the function silc_client_command_pending and
5878 silc_client_command_pending_del and added new function
5879 silc_client_command_pending_check. Removed the
5880 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5883 * Added cmd_ident, current command identifier, to the client
5884 connection context in lib/silcclient/client.h to keep track on
5885 command identifiers used in command sending. Client's command reply
5886 function handling now supports the mandatory command identifiers.
5888 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5889 funtions in client to fully support pending command callbacks.
5891 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5892 as one of the arguments to the application in the command reply
5895 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5896 before first releasing SILC but came back. Now it is removed again
5897 and should come back nomore. The FORWARDED flag was used only
5898 by the JOINing procedure by forwarding the command packet to router.
5899 Now, the JOINing procedure has been changed to more generic (due
5900 to various router environment issues) and FORWARDED is not needed
5901 anymore for anything. The protocol specification is yet to be
5904 Now, removed silc_server_packet_forward from server and the flag
5905 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5907 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Renamed NAMES command to USERS command. The NAMES was named that
5910 due to historical reasons. Now it is renamed. Also, rewrote
5911 parts of the USERS command. The nickname list is not sent anymore
5912 by the server. Only Client ID and mode lists are sent in the USERS
5913 command. Changed this also to the protocol specification.
5915 The client now resolves the names and stuff after it receives
5916 the USERS list from the server when joining to the channel.
5918 * WHOIS and IDENTIFY commands has been changed to support multiple
5919 Client ID's per command. One can now search for multiple users
5920 in the network by sending only one WHOIS or IDENTIFY command.
5921 Changed the code and the protocol specifications.
5923 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5924 uses silc_server_command_whois_parse to parse the request. */
5926 * If normal server, do not parse the WHOIS and IDENTIFY requests
5927 before sending it to the router. Saves some time.
5929 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Fixed JOIN command on client library. Wrong number of arguments
5932 used to crash the client.
5934 * Added silc_server_channel_has_global function to check whether
5935 channel has global users or not.
5937 * Added silc_server_channel_has_local function to check whether channel
5938 has locally connected clients on the channel.
5940 * The silc_server_remove_from_one_channel now checks whether the
5941 channel has global users or not after given client was removed from
5942 the channel. It also checks whether the channel has local clients
5943 on the channel anymore. If it does not have then the channel entry
5944 is removed as it is not needed anymore.
5946 * The silc_server_notify now checks on JOIN notify whether the joining
5947 client is one of locally connected or global. If it is global then
5948 the channel has now global users on the channel and that is marked
5949 to the channel entry. Also, it now saves the global client to
5950 global list who is joining and JOINs it to the channel. This is
5951 for normal server, that is.
5953 Changed silc_server_send_notify_on_channel,
5954 silc_server_packet_relay_to_channel and
5955 silc_server_packet_send_to_channel check if we are normal server
5956 and client has router set (ie. global client) do not send the
5957 message to that client, as it is already routed to our router.
5959 * Implemented LEAVE notify type handling in silc_server_notify
5962 * Tested LEAVE command in router environment successfully. Tested
5963 with two routers, two servers and two clients.
5967 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5969 * Implemented SIGNOFF notify type handling in silc_server_notify
5972 * silc_server_remove_id now removes the client entry from all channels
5973 it has joined and thusly sends SIGNOFF notify type.
5975 * Rewrote the NAMES list generation in server by removing two excess
5976 loops. The lists are created now inside one loop.
5978 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * silc_server_remove_channel_user checks now also global list
5981 for channel and client.
5983 * silc_server_new_channel_user checks now both local and global
5984 list for channel and client. Fixed a bug in client id decoding.
5985 Used to decode wrong buffer.
5987 * silc_server_channel_message checks now both local and global
5988 list for channel entry.
5990 * Tested channel joining (hence JOIN) in router environment
5991 successfully. Tested with two routers, two servers and two
5994 * Tested channel message sending in router environment successfully.
5996 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Added silc_server_save_channel_key into server.[ch] to save the
5999 received channel key in Channel Key payload processing. It is
6000 also used in JOIN command reply handling.
6002 Equivalent function silc_client_save_channel_key added into
6003 client.[ch] into client library.
6005 * Changed JOIN command reply to send information whether the channel
6006 was created or not (is existing already) and the channel key
6007 payload. Changed protocol specs accordingly.
6009 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6010 the request was sent by ID and not by nickname. Crashed on
6013 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6015 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6016 now correctly save the received data.
6018 * silc_server_free_sock_user_data now notifies routers in the
6019 network about entities leaving the network.
6021 At the same time implemented functions silc_server_remove_id
6022 and silc_server_send_remove_id to receive and send REMOVE_ID
6023 packets. The packet is used to notify routers in the network
6024 about leaving entities. The ID removed will become invalid in
6027 * Added function silc_idlist_del_server into server. Removes and
6028 free's server entry from ID list.
6030 * silc_server_private_message function now checks, if we are router,
6031 that the destination ID really is valid ID, naturally.
6033 * In router when NEW_ID packet is received (for new client) the
6034 hash of the Client ID is saved in the ID Cache but the
6035 client->nickname is set to NULL, instead of putting the hash
6038 IDENTIFY command now also checks that client->nickname must be
6039 valid. If it is not if will request the data from the server who
6040 owns the client. Added new function
6041 silc_server_command_identify_check.
6043 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6044 to set the command to already allocated Command Payload.
6046 * Tested private message sending in router environment with two
6047 routers, two servers and two clients. Fixed minor bugs and now
6050 * Fixed segfault from client's NAMES command. Used to crash if
6053 * Forwarded packets must not be routed even if it is not destined
6054 to the receiver. Changed server code comply with this.
6056 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added `require_reverse_mapping' boolean value to ServerParams
6059 structure. If TRUE (not default) the server will require that
6060 the connecting host has fully qualified domain name.
6062 If the reverse mapping is not required and hostname could not be
6063 found the IP address is used as hostname.
6065 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Implemented version string checking to both client and server.
6068 The check is incomplete currently due to the abnormal version
6069 strings used in development version of SILC.
6071 * Changed all command functions in server to use the new
6074 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Changed char *data to unsigned char *data in ID Cache system to
6077 support binary data as ID Cache data. Changed code to support
6078 binary data in lib/silccore/idcache.c.
6080 * Renamed silc_server_packet_relay_command_reply to
6081 silc_server_command_reply as it is normal packet receiving
6082 function. Rewrote the function to accept command replys for
6083 servers and not only for clients.
6085 * Mark remote router always as registered server if we are connecting
6086 to it. Otherwise, commands sent by the router to us are ignored.
6088 * All ID List find routines now returns the ID Cache Entry pointer
6089 as well if requested.
6091 * WHOIS command works now in router environment, tested with two
6092 routers, two servers and two clients.
6094 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6095 in router environment (as it is almost equivalent to WHOIS) but
6096 hasn't been tested thoroughly. Added new functions:
6098 silc_server_command_identify_parse
6099 silc_server_command_identify_send_reply
6100 silc_server_command_identify_from_client
6101 silc_server_command_identify_from_server
6103 * Disabled route cache adding because adding two different ID's with
6104 same IP replaces the old cache entry thus giving wrong route.
6105 The entry->router->connection is always the fastest route anyway
6106 so route cache may not be needed. Of course, new routes maybe
6107 established after receiving the ID when the entry->router->connection
6108 might not be anymore the most optimal.
6110 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Add route cache for received ID for fast routing.
6114 * Added silc_server_packet_route to route received packet on router
6115 that is not destined to us.
6117 * Renamed silc_server_get_route to silc_server_route_get.
6119 * Added id_string and id_string_len fields into SilcServer to
6120 include encoded ServerID for fast comparing without excess
6121 encoding of the ID's.
6123 * Cleaned up WHOIS command on server side. Added following static
6126 silc_server_command_whois_parse
6127 silc_server_command_whois_check
6128 silc_server_command_whois_send_reply
6129 silc_server_command_whois_from_client
6130 silc_server_command_whois_from_server
6132 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6133 arguments in command replies. All command functions should be
6134 updated to use this macro.
6136 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Minor typo fixes on command reply handling on server.
6140 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Added silc_server_command_add_to_channel internal routine to add
6143 the client to the channel after router has created the channel and
6144 sent command reply to the server.
6146 * Added generic silc_server_send_command to send any command from
6149 * Use static buffer with ID rendering instead of duplicating data.
6151 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Fixed a channel user mode bug when joining to a channel server gave
6154 everybody channel founder rights, oops.
6156 * We mark ourselves as the router of the incoming server connection
6157 if we are router ourselves. This way we can check in some packet
6158 sending functions whether it is locally connected server. For
6159 incoming router connections we put NULL.
6161 * For router sending packets locally means now always sending the
6162 packet cell wide; to local clients and local servers. For normal
6163 server sending packet locally means sending it to only local
6166 * Fixed the JOIN command to really work in router environment. If the
6167 channel is created it is always created by the router. Router is
6168 also responsible of making the initial joining to the channel,
6169 sending JOIN notify to the sending server and distributing
6170 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6171 does not exist server doesn't do anything else but forward the
6172 command to the router which performs everything.
6174 * Added silc_server_send_channel_key function to send the Channel Key
6177 * Added silc_server_create_channel_key to create new channel key. The
6178 channel key is now re-generated everytime someone joins or leaves
6179 a channel, as protocol dictates. Note: channel->key_len is the
6182 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6185 packet_receive.[ch] to separate packet sending and receiving
6186 routines. The server.[ch] now includes everything else including
6187 actual packet processing (writing and reading data) and other
6190 Renamed silc_server_private_message_send_internal to
6191 silc_server_send_private_message. The routine is still though
6192 used only to relay private messages as server does not send
6193 private messages itself.
6195 Renamed silc_server_new_channel to silc_server_create_new_channel
6196 and added new function sicl_server_new_channel that handles the
6197 incoming New Channel packet. Added also new sending function
6198 silc_server_send_new_channel to send New Channel Payload.
6200 * Added new function silc_server_notify to process incoming notify
6201 packet to the server/router. Server may then relay the notify
6202 to clients if needed.
6204 * Added new function silc_server_new_channel_user to process incoming
6205 New Channel User packet. Router will redistribute the packet and
6206 send JOIN notify to its local clients and locally connected servers
6207 if needed. Normal server will send JOIN notify to its local client
6208 on same channel when received this packet. Added also corresponding
6209 sending function silc_server_send_new_channel_user to sent the
6212 * Added boolean route argument to send_notif_to_channel and
6213 packet_send_to_channel functions to attempt to route the packet
6214 if it is TRUE and send only locally if it is FALSE.
6216 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * silc_server_replace_id now broadcasts the received replace ID
6219 packet if it is not broadcast packet already. The router must
6220 broadcast to inform other routers about changed ID.
6222 * Added backpointer to server's router into SilcServer context in
6223 silcd/server_internal.h.
6225 * Fixed silc_server_packet_broadcast to send correct broadcast
6228 * The channel key is now distributed to the local client as soon
6229 as it is received from the router (in router environment) so that
6230 no other packet may be sent for the channel until client has
6233 * silc_server_remove_channel_user now broadcasts the received
6234 Remove Channel User packet if it is not broadcast packet already.
6235 The router must broadcast to inform other routers about removed
6238 * Added users field into SilcPacketContext that is a reference count
6239 of the context. One can increase the reference count by calling
6240 silc_packet_context_dup which is now changed to just increase the
6241 reference count instead of duplicating the data. The reference
6242 count is decresed by calling silc_packet_context_free that will
6243 free the data after the reference count hits zero.
6245 For now on the packet context and everything allocated into it
6246 (including the raw packet from network) must be freed by calling
6247 the new silc_packet_context_free function. Added also new function
6248 silc_packet_context_alloc that must be used now to allocate the
6249 context. This also means that if a routine is asynchronous from
6250 silc_[client/server]_packet_parse_type the packet context must
6251 be duplicated by calling silc_packet_context_dup. Otherwise it
6252 gets free'd after silc_[client/server]_packet_parse_type returns.
6253 Also, one must remember that if packet is duplicated then its
6254 reference count must be decresed by calling the free function as
6255 many times as it was duplicated.
6257 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6258 from both client and server.
6260 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Made joining to a channel working in router environment.
6264 * Cleaned up JOIN command on server side and create function
6265 silc_server_command_join_channel internal routine to make the
6268 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * Changed silc_command_pending list to SilcDList. Also, added
6271 `ident' field to SilcServerCommandPending structure to identify
6272 the reply and to call correct callback.
6274 Added silc_server_command_pending_check function to replace the
6275 corresnponding macro. The silc_command_pending list is not
6278 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6279 to set identifier to previously allocated Command Payload. It
6280 is used to set identifier for command when resending Command
6283 * Added silc_command_payload_encode_payload to encode Command
6284 Payload buffer from SilcCommandPayload structure.
6286 * Added silc_argument_payload_encode_payload to encode Argument
6287 payload buffer from SilcArgumentPayload structure.
6289 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Changed WHOIS command to support router connection on server side.
6292 The whois request is always sent to router unless the server is
6293 standalone server. After server has received the reply from the
6294 router will it send the reply to the client.
6296 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6297 broadcast received broadcast packet. The function is used only
6298 by router. The broadcast packet is always sent to the router's
6301 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6302 render given ID to printable string, for log files for example.
6304 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Made basic router to router connections working. At least they
6307 can now connect to each other but nothing really works the way
6308 they are supposed - yet.
6310 * Added new initiator token to RouterConnection configuration
6311 file in silcd/serverconfig.[ch]. It is used to tell whether we
6312 are the initiator to the remote router or whether we'll expect
6313 the other end to connect.
6315 * Moved registering of listener task to silc_server_init, hence
6316 the server starts listenning as soon as it is run, even if it
6317 does not have connections to other routers. Let's see how well
6320 * Changed default connection retry timeouts for more suitable in
6323 * Removed cipher and such arguments from silc_idlist_add_client
6324 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6325 Added new function silc_idlist_add_data to add the keys and stuff
6328 * Added SilcIDListData structure and added it to SilcClientEntry
6329 and SilcServerEntry as their first field in the structure. This
6330 way we can explicitly cast the ID entries to the SilcIDListData
6331 structure and get common data for the entries. In past, we had
6332 to first check what type of connection it is and then cast it to
6333 correct ID entry type. Now, we can directly cast the opaque
6334 pointer to the SilcIDListData (no matter what ID entry it actually
6335 is) and get the data needed.
6337 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6340 in some circumstances even if threre were timeout tasks, though not
6341 IO tasks, but tasks anyway. Now fixed.
6343 * Defined SilcServerConnection structure to hold connection specific
6344 stuff about directly connected servers and routers. The definition
6345 is currently in silcd/server_internal.h. I thought about having
6346 a bit more important role fro this struct but for now it is used
6347 only when connecting to other server (or router actually).
6349 * Added connecting retry support in server when connecting to
6350 router(s). The retry feature implement exponential backoff
6351 algorithm. Also, added SilcServerParams structure to hold default
6352 parameters for server. For now, it include these retry settings
6353 and are hard coded. After server is moded to be as Silc Server
6354 Library this structure will be more important.
6356 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Changed client librarys channel->clients table to SilcList and
6359 changed code accordingly.
6361 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Changed client's channel table to SilcList and changed code
6364 accordingly. Also changed SilcChannelClientEntry to include back-
6365 pointer to the channel so that client entry can use that structure
6366 as list as well and we have fast cross-reference to the channel.
6367 This change dramatically decreased the complexity of channel
6368 handling with client entry and vice versa (removed one extra
6369 loop when searching for channel entry from many functions).
6371 * Changed server->sim from table to SilcDList and changed code
6374 * NAMES command can now be used from user interface. It will show
6375 the user list on the channel, neatly.
6377 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6378 Code now saves realname of the user if it becomes available.
6380 * Renamed configure.in to configure.in.pre and made ./prepare
6381 script to automatically add correct version string to
6382 configure.in which it creates from configure.in.pre.
6384 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6386 * NAMES command reply now shows users mode with the nickname when
6389 * Moved silc_client_ch[u]mode[_char] functions from
6390 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6391 place sucks, they are utility functions and should be in some
6394 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6396 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6399 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Added TRQ (efficient deque and list library) into lib/trq. This is
6404 a very good list library that is currently used in the SILC. Defined
6405 SilcList API over the library because I didn't like the API very
6406 much. See lib/trq/silclist.h for the API and examples of how to
6407 use the API. Fixed various places in the code to use the new
6408 SilcList API. The SilcList is meant for lists that has a structure
6409 already defined as a list. It is not suitable to add just some
6410 context to the list (in TRQ, the context is the list actually).
6412 So, I defined SilcDList that can be used for the purpose where
6413 predefined list structure does not exit. This can be used as
6414 such list. Now some context just can be added to the SilcDList.
6415 Currently this list is not used in the SILC just yet, though there
6416 are a lot places where this can replace dynamically allocated
6417 tables and I will fix these places, later, to use SilcDList.
6418 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6419 and use TRQ internally).
6421 Also fixed some annoying warning messages that the original TRQ
6422 code generated. Also minor changes to TRQ's Makefile.in.
6424 * Added support for querying by Client ID to both WHOIS and
6425 IDENTIFY commands into server, as required by the protocol.
6427 * Removed method function pointers from SilcBuffer structure. They
6428 weren't used to anything and just increased the context size for
6429 no good reason. This change also made silc_buffer_alloc and
6430 silc_buffer_free functions inline functions.
6432 * Disabled command flooding detection support until it's fixed so
6433 that it accepts commands in but does not execute them more than once
6436 * Added silc_net_localhost(), to return local hostname, into
6437 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6438 that must be initialized before calling silc_client_init.
6440 * Added new function: silc_server_send_notify_on_channels to send
6441 notify messages to all channels client has joined. It is assured
6442 that the message is sent only once per client.
6444 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6445 lib/silcutil/silcutil.[ch] as silc_format function. The new
6446 function is generic and is used by server as well, not only by
6447 the logging routines.
6449 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6450 the provided version string was not acceptable. Added new function:
6451 silc_ske_check_version into lib/silcske/silcske.h. The function
6452 must be implemented by the application (client or server) and it
6453 does not reside in the SKE library. The function checks the version
6454 string remote end sent.
6456 * Added back pointers (to opaque context and to SilcSocketConnection)
6457 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6459 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6460 duplicate packet context structure.
6462 * Changed `notify' client operation to send same arguments as client
6463 receives from server except for ID's. ID's are mapped to correct
6464 ID entry and that is returned. Also, if channel entry is not sent
6465 by server but the notify is for channel the channel entry is sent
6466 to application (otherwise application doesn't know that it is for
6467 channel (library gets it from packet's Destination ID)).
6469 * Added silc_client_remove_from_channels into client library to
6470 remove a client from all channels it has joined to. Used when
6471 received SIGNOFF notify from server. Added also new function
6472 silc_client_replace_from_channels to replace old ID entry with
6473 new ID entry on all channels. Used when received NICK_CHANGE
6476 * Fixed ID Cache list handling in silc_idlist_get_client in
6477 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6478 to get (or query) client by ID.
6480 * Updated TODO list.
6482 * Added connection authentication status message defined by the
6483 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6484 support for these into the code in client and server side.
6486 * Added generic function silc_client_send_command to send any command
6487 with variable argument list. Application should use this function
6488 to send commands if the command functions provided by the library
6489 does not suite for the application's user interface needs.
6491 * Added new `failure' client operation. Application is notified about
6492 received failure packet if client is executing a protocol. In this
6493 case the protocol's execution has failed.
6495 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6496 is required by the protocol.
6498 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6499 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6502 * Added status flag to SilcSKE object to indicate realtime status
6503 of the SKE protocol.
6505 * Application receives now exactly same command reply arguments as
6506 the library receives from server. However, if ID is received the
6507 corresponding ID entry is returned to the application (eg. Client
6508 ID is mapped to correct SilcClientEntry entry and that is returned).
6509 Changed command_reply client operation due to this change.
6511 * Changed all ID's in commands and in command replys as ID Payloads.
6512 Change affected both client and server side codes.
6514 All ID's sent in SILC network (with execption of ID's in SILC
6515 Packet header) are sent in ID Payload to support variable length
6518 * Server now notifies nick changes and notifies all clients on
6519 the channels about the new nickname (about the new Client ID,
6522 * Implemented CMODE command to change channel modes. Supports all
6523 channel modes defined by the protocol specs except ban and invite
6524 lists. (Also, private channel key mode is supported but support for
6525 setting private channel key in client is missing, thus, this mode
6526 has no effect on client side (except that server requires that the
6527 client uses private channel key and normal channel traffic does not
6530 Also, invite mode works per se, but INVITE command does not work
6531 yet correctly, so you can set channel as invite only channel but
6532 inviting clients to the channel does not work (it is yet to be
6533 thought what's the best way to do it).
6535 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6536 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6537 Implemented CUMODE command to change user's mode on the channel.
6538 Supports all modes defined by the protocol specs.
6540 * Added NAMES command reply to return users modes on the channel.
6542 * Removed unnecessary and slow ciphers from lib/silccrypt.
6544 * Set SO_KEEPALIVE option to connection sockets by default.
6546 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6548 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6549 redefined the Notify Payload into protocol specs.
6551 * Added silc_id_payload_parse_id to get ID directly from raw
6554 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6557 accept searching by Client ID as well.
6559 * Added support for LEAVE and SIGNOFF notify types in client library.
6561 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6562 to parse ID Payload from raw data.
6564 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Added flags parameter into silc_ske_assemble_security_properties
6567 function in lib/silcske/silcske.[ch].
6569 * Changed notify client operation to fit better for notify messages
6570 sent by server. The notify payload received from server is now
6571 passed to the application (after parsing it to SilcNotifyPayload).
6572 It is application's responsibility to retrieve the arguments
6573 from the payload and show the message the way it wants. The message
6574 sent by server is implementation specific.
6576 * Changed public keys to comply with the protocol specification.
6577 Old public keys are not supported anymore and are not compatible.
6579 * Removed nickname from Channel Payload as the latest draft removed
6580 it. The client must resolve the nickname from the NAMES command
6581 reply received when it joined the channel.
6583 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6585 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6587 * Fixed some errors in protocol specification drafts.
6589 * Created lib/silccore/silcnotify.c to implement Notify Payload
6590 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6591 generic payloads described by protocol specifications. The file
6592 includes implementations for ID Payload and Argument Payload.
6594 * Changed Command Payload implementation to use the new Argument
6595 Payload. Changed command_xxxx_payload to command_payload_xxxx
6596 to comply with SILC coding conventions.
6598 * Added suppport for Argument Payload handling in Notify Payload
6599 implementation as protocol requires it. Added the new support
6600 into server and client lib as well.
6602 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Added support for multiple nicknames on same channel. [n] is
6605 added locally to the nickname if there are more than one same
6606 nicknames on the channel.
6608 * Server now sends all nicknames that matched WHOIS request.
6609 Client also shows the list received from server.
6611 * Added TOPIC command to client side. User can now set and show
6612 current topic on channel.
6614 * Added MOTD command to client and server. Also, server sends the
6615 motd when client connects to the server.
6617 * Changed version strings to comply ISO 8601.
6619 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Fixed protocol error handling in client library. It should now
6622 cope even if the SKE fails for some reason.
6624 * Made new protocol specification drafts for submitting to IETF.
6626 * Implemented TOPIC command to server in silcd/command.c.
6628 * Added two new notify types into lib/silccore/silcnotify.h:
6629 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6630 notify nickname change and topic setting/change on a channel.
6632 * API change of command_reply operation in client library. The
6633 application gets now the status type received from server as well.
6635 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6639 * Cras fixed and optimized the packet handling even further and
6640 it should work now. Minor change to the prototype of function
6641 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6643 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * Added new function into lib/silcutil/silcschedule.[ch]:
6646 silc_schedule_with_fd to select() a specified fd. The function
6647 returns after timeout expires or data arrives or goes. The
6648 function is used by packet routines to wait that all data is
6649 received from network.
6651 * Fixed data reading from network in lib/silccore/silcpacket.c.
6652 The code now assures that all data is read from the fd and then
6653 continues packet processing. This was a bug fix since the code
6654 used to drop some data in some circumstances.
6656 * Added new function into lib/silcclient/client.[ch]:
6657 silc_client_start_key_exchange to start key exchange after
6658 connection has been established to server. The code internally
6659 now uses this funtion but its main purpose was to provide it
6660 for applications that perform their own connecting. After
6661 application has created a connection it merely calls this
6662 function to start the key exchange between client and server.
6663 The library takes care of everything else after that.
6665 Updated also lib/silcclient/README to explain the usage of
6668 * Do not send to application information that connection has
6669 been established. Application gets notified it by connect
6672 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6674 * Applied cras's patch to add silc_schedule_one function. The
6675 function runs scheduler once and returns.
6677 * Fixed the scheduler after cras messed it up. The timeout
6678 handling works now as it's supposed to work.
6680 * Added into lib/silccore/ silcnotify.h to include notify
6681 message types support. Changed silc_server_send_notify*
6682 functions, in server.[ch], to support those new notify types.
6683 Added the support for the notify types into client library,
6684 as well. Added new notify client operation into ops.h in
6687 * Changed silc_server_packet_send_to_channel to send normal
6688 packets instead of just channel message packets. The function
6689 is now used to send the notify packets to channels. It is not
6690 used to send channel message packets anymore, as server never
6693 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6694 va_arg()s as it seems to require it nowadays. I guess, if SILC
6695 is compiled with older va_arg() the new code should work anyway.
6697 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Splitted core library. Core library (lib/silccore) includes
6700 now only SILC protocol specific core (and common) components.
6701 Created new utility library (lib/silcutil) that includes more
6702 generic purpose stuff. The stuff for util library was taken
6703 from the old core library. This was minor and easy split.
6705 * Created SILC Client Library (lib/silcclient) that includes
6706 implementation of the SILC client without user interface. This
6707 was major move from silc/ directory. The code has been changed
6708 so that it is transparent towards the user interface. The
6709 silc/ directory includes now the same user interface as before
6710 and it uses the new client library. Read lib/silcclient/README.
6711 Basicly, the client library performs everything else related
6712 to SILC except user interface handling. Also, configuration
6713 files are considered to be part of user interface and library
6714 does not handle them.
6716 This change also changed a lot of structures, function naming etc.
6717 Most important change was that SilcClientWindow object was
6718 renamed to SilcClientConnection in the client library. Created
6719 also new file lib/silcclient/ops.h. Also added new files
6720 silc/local_command.[ch] and silc/client_ops.[ch].
6722 All these changes were made to make it easier for user interface
6723 designers to create what ever user interface for the SILC client
6726 It is also expected that the server will be moved to lib
6727 directory as well and SILC Server Library will be created;
6728 sometimes in the future.
6730 * Removed Local commands from lib/silccore/silccommand.h as
6731 they are application specific and new client library does not
6732 handle any of those anymore.
6734 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6735 old client implementation in silc/.
6737 * Added support for callback functions in SILC_LOG_* macros.
6738 Application can now set its own callbacks that will be called
6739 instead of using the default functions that will always print
6740 the debug messages to stderr (or stdout). Also, debugging can
6741 now be disabled by setting silc_debug to FALSE and re-enabled by
6742 setting it to TRUE. Note, that logging will still work even
6743 if debugging is disabled.
6745 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6746 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6747 silc_log_reset_debug_callbacks.
6749 * To enable debugging in silc client one must give now -d
6750 option on command line.
6752 * Changed silc_schedule_init to automatically allocate task queues
6753 if they are not allocated before calling it.
6755 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Added GMP 3.1 into math library.
6759 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6762 a channel in SILC network. The packet is used by servers and
6763 routers to notify other routers that user has left a channel.
6764 This little feature was missing until now. Added the feature
6765 to protocol specification as well.
6767 Added functions: silc_server_send_remove_channel_user and
6768 silc_server_remove_channel_user into server.[ch].
6770 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6771 lib/silccore/silcpacket.h. However, they are not implemented
6774 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Fixed joining to a channel and sending channel messages
6777 between server and router. The channel message sending should
6778 now work inside a cell.
6780 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Fixed the private message sending between server and router.
6783 The private message sending should now work inside a cell.
6785 * Added silc_server_replace_id into server.[ch] to replace
6786 existing ID in the SILC network.
6788 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6789 and silc_idlist_replace_server_id into idlist.[ch] in server.
6791 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * Fixed the server to server connections. Server can again now
6794 connect to router. Router to router connections probably does
6797 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6799 * Added dynamic protocol registering support. Now protocols can
6800 registered and unregistered on the fly. Patch by cras.
6802 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6804 * Added lib/contrib directory to hold routines that some platforms
6805 don't have but are needed by SILC.
6807 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6808 into lin/contrib to provide getopt() and getopt_long() for
6809 those who don't have it.
6811 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6813 * Added AWAY command to client. When away message is set and
6814 client receives a private message packet the client automatically
6815 replies to the sender with the away message.
6817 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6818 bug seemed to be the cause of recent problems when compiling
6821 * Added version detection support to SKE protocol specification
6822 and added the new changes to the SKE implementation as well.
6823 There were other minor changes in the SKE protocol as well.
6825 Many changes in lib/silcske/silcske.[ch] and in
6826 lib/silcske/payload.[ch].
6828 * Added ^U functionality, clear input line. Patch from cras.
6830 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Mainly small bugfixes on core library. Fixed some debugging
6833 logging and buffer overflow in silclog.c.
6835 * Updated config.sub and config.guess on the distribution tree.
6837 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Added command lagging support in server. Client may execute
6840 commands now only once in two seconds.
6842 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Optimized packet reception. MAC computation and checking is now
6845 also more optimized. A lot previously duplicated code is now
6846 used as generic by both client and server.
6848 * Fixed key pair generation in clientutil.c
6850 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Added into lib/silccore/silcbufutil.[ch] new function;
6853 silc_buffer_realloc.
6855 * Moved generic packet sending/encryption functions to
6856 lib/silccore/silcpacket.[ch] from client and server. Some
6857 rewriting of the functions.
6859 * Moved all generic packet reception/decryption functions to
6860 lib/silccore/silcpacket.[ch] from client and server. The
6861 packet processing is now much cleaner in both client and server.
6862 These were major changes in both client and server.
6864 * Created many common functions in server to do packet sending.
6865 Previously code were duplicated a lot, this has been removed
6868 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Rewrote major parts of the ID cache system. Don't know
6871 whether it is better now or not but at least the API is more
6874 * Major rewrite on ID cache stuff on client because of the ID
6875 cache API changes. Added idlist.c to client.
6877 * Also major rewrite on ID cache stuff on server as well.
6878 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6879 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6880 in hand, instead they are all put into the ID cache system now.
6881 All server_idlist_* routines uses ID cache now instead of
6882 traversing its own lists (those lists does not exist anymore).
6883 SilcIDList though still exists. Also, SilcXXXEntry's are
6886 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Finally made the SKE implementation compliant to the protocol
6889 specification. All mp integers are now binary encoded as
6890 opposed being HEX encoded.
6892 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6895 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6896 functions: silc_[encode/decode]_pem. Also added function
6897 silc_encode_pem_file to PEM encode with newlines ('\n') for
6900 * SILC public keys are now encoded either PEM or binary. Same
6901 option is for private keys as well. By default private keys
6902 are binary encoded and public keys PEM encoded. Silly HEX
6903 encoding were removed.
6905 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6906 function to create fingerprints.
6908 * Fixed a bug in SHA1; does not change the original data anymore.
6910 * Partly implemented INFO command on client and server side.
6911 Fixed CLEAR command. Changes to SERVER command; show current
6912 server(s) when giving command without arguments. Added
6913 VERSION command to client.
6915 * Added check to server that unregistered connections cannot
6916 execute commands (unless it is specificly allowed).
6918 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Fixed screen refresh.
6922 * Fixed channel joining bug from client. On some circumstances
6923 client tried to join to a channel it had already joined.
6925 * Added public key verification process into client's protocol.c.
6926 The client now verifies the public key from user and saves
6927 it into ~./silc/serverkeys/ directory.
6929 Added into: clientutil.[ch]: silc_client_verify_server_key.
6931 * Changed SKE protocol's silc_ske_initiator_finish function
6932 to accept callback function that verifies the received public
6933 key. Removed old silc_ske_verify_public_key function.
6935 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6938 silc_pkcs_private_key[_data]_set.
6940 * Made the password and public authentication more cleaner in
6941 server's protocol.c.
6943 * Removed historic and obsolete protocol `channel_auth' from
6944 both client and server.
6946 * Removed wrong way of sending command status messages from
6947 server to client in server's command.c. The old way violated
6948 protocol specification.
6950 Changes to silccore/silccommand.[ch]: removed
6951 silc_command_encode_status_payload -> not needed anymore,
6952 changed silc_command_encode_payload_va to accept extra
6953 argument on variable argument list. The argument type must
6954 now be provided to the function. Also, added new function:
6955 silc_command_encode_reply_payload_va which is same as
6956 normal command_encode_payload_va except command status type
6957 is provided as extra argument.
6959 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Added ~./silc directory handling. The directory includes the
6962 public and private keys for the client.
6964 Added silc_client_check_silc_dir, silc_client_create_identifier
6965 and silc_client_load_keys.
6967 * Implemented SILC protocol compliant public key. Added public
6968 and private key saving to and loading from files.
6970 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6971 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6972 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6973 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6974 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6976 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6977 silc_pkcs_load_[public/private]_key.
6979 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Added silc_server_get_route (route.[ch]) to get connection
6982 data for the fastest route for given ID.
6984 * Implemented INVITE command on client and server. The command
6985 were re-defined in the SILC Protocol Specification and the
6986 implementation now complies with the specification.
6988 * Implemented PING command on client and server.
6990 * Implemented NAMES command on client and server. The server side
6991 supports currently only normal server not router server yet.
6992 Some changes to NAMES definition in SILC protocol specification.
6994 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Implemented LEAVE command on client and server.
6998 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6999 again. This change was made to the protocol as well. Server
7000 should not violate the protocol specification anymore.
7002 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7004 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7005 was tested. SOCKS4 was not but should work anyway.
