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

586 lib/silccore/silcidcache.c
591 * ROBOdoc documented the lib/silcske/groups.h file and a
592 bit changed the interface for better.
594 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
596 * Update the client entry context in the ID cache after
597 nick change. Affected file lib/silcclient/command.c.
598 Fixes the CUMODE command when regaining founder privileges,
599 and a little WHOIS problem.
601 * Fixed silc_net_gethostbyname to correctly call the
602 inet_ntop. Affected file lib/silcutil/silcnet.c.
604 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
606 * Added IPv6 support checking to the configure.in.pre, added
607 also --enable-ipv6 option to override the check. Affected
608 file configure.in.pre.
610 * The silc_thread_create now calls the start function
611 directly if threads support is not compiled in. Removes

632 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
634 * Fixed LIST command reply sending in server. Affected file
637 * Server now sends the kicker's client ID in the KICK notify
638 to the kicked client. Affected file silcd/command.c.
640 * The client library now parses the kickers client ID and
641 UI displays it. Affected files lib/silcclient/client_notify.c
642 and irssi/src/silc/core/silc-channels.c, module-formats.c.
644 * Made all payload parsing function prototypes consistent.
645 They all take now const unsigned char * and uint32 pair as
646 the payload data instead of SilcBuffer. Changes all around
647 the source tree. Other unsigned char* -> const unsigned char*
648 changes around the tree as well.
650 * Optimized SFTP client and server packet sending not to
651 allocate new buffer for each packet but to recycle the
652 first allocated buffer. Affected files are
653 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
655 * Optimized the SFTP client to use SilcList instead of
656 SilcDList for requests, because it is faster. Affected file
657 is lib/silcsftp/sftp_client.c.
659 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
660 into lib/silccore/silcid.[ch].
662 Renamed silcpayload.[ch] into silcargument.[ch].
664 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
666 * If client entry is deleted with active key agreement
667 session, abort the session.
669 The silc_client_abort_key_agreement now calls the completion
670 callback with new SILC_KEY_AGREEMENT_ABORTED status.
672 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
675 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
677 * Don't use __restrict in older GCC's. Affected file is
678 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
680 * silc_net_localhost now attempts to reverse lookup the
681 IP/hostname. Affected file lib/silcutil/silcnet.c.
683 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
684 command. It can be used to gain founder privileges at
685 the same time when joining the channel.
687 Defined that the SILC_NOTIFY_TYPE_KICKED send the
688 kicker's client ID as well. Updated protocol specs.
690 Defined that the server must send SILC_COMMAND_IDENTIFY
691 command reply with error status to client who sent
692 private message with invalid client ID.
694 Updated the protocol specification.
696 * Added silc_server_send_command_reply to send any
697 command reply. Affected file silcd/packet_send.[ch].
699 * Added silc_id_payload_encode_data to encode ID payload
700 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
702 * The server now send IDENTIFY command reply with error
703 status if client ID in private message is invalid. Affected
704 file silcd/packet_receive.c.
706 * Save the server key file with server's IP address in
707 the filename instead of hostname. The affected file is
708 irssi/src/silc/core/client_ops.c.
710 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
712 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
715 * Added libtool support for compiling shared objects in
716 lib/silcsim. Affected file configure.in.pre and
717 lib/silcsim/Makefile.am. Original patch by cras.
719 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
721 * Pid file configuration, and server's config file fixes
722 patch by toma. Updated CREDITS file.
724 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Fixed silc_client_channel_message to not try to decrypt
727 the message twice if it resolved the destination client
728 information. This could cause of dropping one channel
729 message. Affected file lib/silcclient/client_channel.c.
731 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
733 * Added silc_client_run_one into lib/silcclient/silcapi.h and
734 lib/silcclient/client.c. This function is used when the SILC
735 Client is run under some other scheduler, or event loop or
736 main loop. On GUI applications, for example this may be
737 desired to used to run the client under the GUI application's
738 main loop. Typically the GUI application would register an
739 idle task that calls this function multiple times in a second
740 to quickly process the SILC specific data.
742 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
744 * Fixed silc_server_drop() for dropping the supplementary
745 groups as well, this could cause a security hole on some
748 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
750 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

754 to run server on foreground. A patch by debolaz.
755 Affected files silcd/server.c, silcd/silcd.c.
757 * Fixed MOTD to return the MOTD file server name. Affected
758 file silcd/command.c.
760 * Added INFO command reply handling to the Irssi SILC Client.
761 Affected file irssi/src/silc/core/client_ops.c.
763 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Fixed the silc_idcache_list_* routines to really support
766 the dynamic list. Fixes a crash. Affected file is
767 lib/silccore/silcidcache.c.
769 * Fixed the LIST command reply to really call LIST command's
770 pending callbacks. Affected file silcd/command_reply.c.
772 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Update conn->local_entry->nickname after giving NICK
775 command. Affected file lib/silcclient/command.c.
777 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
779 * Added the [pid] option to the silcd configuration file
781 Affected files: serverconfig.[ch] and silcd.c

785 * Save fingerprint in WHOIS command reply in server.
786 Affected file silcd/command_reply.c.
788 * Fixed NICK commands pending callback registration.
789 Affected file lib/silcclient/command.c.
791 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
793 * Use ++server->cmd_ident when sending commands in server,
794 instead of random number. Affected file silcd/command.c.
796 * Fixed GETKEY command reply to call actually GETKEY pending
797 command callbacks. Affected file silcd/command_reply.c.
799 * A bit stricter check for nicknames. Check for same nickname
800 in NICK command also. Affected file silcd/command.c.
802 * Do not call INFO command everytime client ID changes, only
803 during first connecting. Affected file lib/silcclient/client.c.
805 * Set the new nickname only after successful command reply for
806 NICK command is returned by server. Affected file
807 lib/silcclient/command.c.
809 * Remove nicknames from nicklist during server_signoff notify.
810 Should fix /NAMES bit more. The affected file is
811 irssi/src/silc/core/silc-channels.c.
813 * Added `fingerprint' field to the SilcIDListData in the
814 silcd/idlist.h to hold the fingerprint of the client's
817 Send the fingerprint of the client's public key in WHOIS
820 Affected files silcd/command.c, and silcd/idlist.[ch].
822 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
823 create fingerprint from given data.
825 * Show the fingerprint of the client's public key in WHOIS.
826 Affected files irssi/src/module-formats.[ch] and
827 irssi/src/silc/core/client_ops.c.
829 * Format the multiple same nicknames also during JOIN and
830 NICK_CHANGE notifys. Affected file is
831 lib/silcclient/client_notify.c.
833 * Do not print error on screen for invalid private message
834 payload since it can come if someone is sending private
835 messages with wrong key. Affected file
836 lib/silccore/silcprivate.c.
838 * Fixed multiple concurrent /PING crash. Affected file
839 lib/silcclient/command.c.
841 * Changed the wrong ID encoding. All IP addresses must be
842 in MSB first order in encoded format. They were encoded
843 wrong and was in LSB format. Affected files are
844 silcd/serverid.c, lib/silcutil/silcutil.c.
846 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
848 * Call the `connect' client operation through the scheduler
849 in case of error. Affected file lib/silcclient/client.c.
851 * Call the `failure' client operation even if the error
852 occurred locally during a protocol. Affected file is
853 lib/silcclient/protocol.c.
855 * Added support of sending LIST command to router from normal
856 server. This way normal server can get list of all channels
857 in the network too. Fixed the channel list sending in the
858 server too. Affected files are silcd/command.c, and
859 silcd/command_reply.[ch].
861 * Added silc_server_update_channels_by_server and
862 silc_server_remove_channels_by_server. They are used during
863 disconnection of primary router and in backup router protocol.
864 Affected file silcd/server_util.[ch], silcd/server.c and
865 silcd/server_backup.c.
867 * Fixed channel adding to global list in IDENTIFY command
868 reply in server. Affected file silcd/command_reply.c.
870 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
872 * If the incoming packet type is REKEY or REKEY_DONE process
873 that packet always synchronously. Fixes yet another MAC
874 failed error on slow (dialup) connections. Affected file
875 lib/silcclient/client.c and silcd/server.c.
877 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
879 * Call check_version SKE callback for initiator too. Affected
880 file lib/silcske/silcske.c.
882 * Implemented fix for security hole found in the SKE that was
883 fixed in the specification few days back; the initiator's
884 public key is now added to the HASH value computation.
885 Added backwards support for the old way of doing it too, for
886 old clients and old servers. Affected file is
887 lib/silcske/silcske.c.
889 * Enabled mutual authentication by default in SKE. If initiator
890 is not providing mutual authentication the responder will
891 force it. This will provide the proof of posession of the
892 private key for responder. The affected files are
893 lib/silcclient/protocol.c and silcd/protocol.c.
895 * Do not cache anymore the server's public key during SKE.
896 We do mutual authentication so the proof of posession of
897 private key is done, and if the server is authenticated in
898 conn auth protocol with public key we must have the public
899 key already. Affected file silcd/protocol.c.
901 * Added new global debug variable: silc_debug_hexdump. If
902 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
903 file lib/silcutil/silclog.[ch].
905 * Fixed compilation warning due to char * -> const char *.
906 Affected files lib/silcutil/silcnet.h, and
907 lib/silccore/silcauth.[ch].
909 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Fixed CMODE command when new channel key was created. If
912 the creation failed the old key was removed. Next time giving
913 same command would crash the server since the old key was
914 freed already. Affected file silcd/command.c.
916 * Fixed the silc_server_announce_get_channels to not crash
917 on reconnect. Affected file silcd/server.c.
919 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Added silc_log_set_debug_string function to set a regex
922 string to match for debug output. Only the function names,
923 or filenames matching the given debug string is actually
924 printed. This way it is possible to filter out those debug
925 strings that user is not interested in.
927 Fixed a bug in silc_string_regexify.
929 Affected files lib/silcutil/silclog.[ch], and
930 lib/silcutil/unix/silcunixutil.c.
932 * Changed the -d options in both server and Irssi SILC client
933 to take the debug string as argument. Affected files
934 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
936 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Added silc_hash_babbleprint to create a Bubble Babble
939 Encoded fingerprint. The encoding is developed by Antti
940 Huima (draft-huima-babble-01.txt), and it creates human
941 readable strings out of binary data. Affected file
942 lib/silccrypt/silchash.[ch].
944 * Print the babble print now in addition of fingerprint as well
945 in Irssi SILC client. Affected files are
946 irssi/src/fe-common/silc/module-formats.[ch],
947 irssi/src/fe-common/silc/core/client_ops.c.
949 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Fixed a security problem found in SKE. The initiator's
952 public key too is now added to the HASH hash value creation
953 which is signed by the responder to create the SIGN value.
954 This will prevent anyone in the middle to lie to the responder
955 about the initiator's public key. If this is done now, the
956 man in the middle will get caught. Updated the protocol
959 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Better installation directory handling. Configure module
962 paths and other paths automatically to example_silc* files
963 in doc/. A patch by toma.
965 * Fixed compiler warning from MPI library, and from SILC RNG.
968 * Added SILC_SERVER_PID_FILE to define the pid file for server.
969 It can be configured with ./configure. A patch by toma.
971 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Find correct make to use in prepare-clean. A patch by
974 toma. Affected file prepare-clean.
976 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
978 * Added irssi variables use_auto_addr, auto_bind_ip,
979 auto_bind_port and auto_public_ip.
981 * Changed the interface for silc_client_send_key_agreement
982 in lib/silcclient/silcapi.h
986 irssi/src/silc/core/silc-core.c
988 lib/silcclient/silcapi.h
989 irssi/src/silc/core/silc-channels.c
990 lib/silcclient/client_keyagr.c
993 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
995 * Added silc_pkcs_public_key_compare to compare two
996 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
998 * Check that the client who set the founder mode on the
999 channel is the same client that is giving the founder
1000 mode to itself. It is done by comparing the saved public
1001 key (it is saved even in the authentication is passphrase).
1002 Affected file silcd/command.c.
1004 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Do not process packet for disconnected socket connection.
1007 Affected file lib/silccore/silcpacket.c.
1009 * Process the DISCONNECT packet through scheduler in the
1010 client library. Affected file lib/silcclient/client.c.
1012 * Fixed the silc_client_packet_parse to not to increase
1013 the packet sequence number if the conn->sock and the
1014 current socket connection is not same. This can happen
1015 for example during key agreement when the conn includes
1016 multiple socket connections (listeners). Affected file
1017 lib/silcclient/client.c.
1019 * The sender of the file transfer request now provides also
1020 the pointer (listener) for the key exchange protocol. If
1021 the listener cannot be created then it sends empty key
1022 agreement and lets the receiver provide the listener.
1024 Added `local_ip' and `local_port' arguments to the
1025 silc_client_file_send. If they are provided they are used,
1026 if not then it will attempt to find local IP address, if
1027 not found or bind fails then the remote client will provide
1030 Affected files are lib/silcclient/client_ftp.c and
1031 lib/silcclient/silcapi.h.
1033 * Extended the FILE SEND command to support defining the
1034 local IP and port for key exchange listener. They are
1035 optional. Affected file irssi/src/silc/core/silc-servers.c.
1037 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1039 * Defined to WHOIS command reply the sending of fingerprint
1040 of the client's public key (if the proof of posession of the
1041 corresponding private key is verified by the server).
1042 Updated to the protocol specification.
1044 * Added support of receiving the client's public key's
1045 fingerprint in command reply in client library. Affected
1046 file is lib/silcclient/command_reply.c, and
1047 lib/silcclient/idlist.[ch].
1049 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Do not send over 128 chars long nickname to the server
1052 in NICK command. Affected file lib/silcclient/command.c.
1054 * Do not send over 256 chars long channel names to the server
1055 in JOIN command. Affected file lib/silcclient/command.c.
1057 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Assure that silc_server_close_connection cannot be called
1060 twice for same socket context. Affected file is
1063 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Send error message to application if opening file for
1066 writing during file transfer fails. Affected file is
1067 lib/silcclient/client_ftp.c.
1069 Remove all file transfer sessions for a client that we're
1070 removing from ID cache.
1072 Affected file is lib/silcclient/client_ftp.c.
1074 * Fixed silc_net_addr2bin to return correct address. Affected
1075 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1077 * Fixed file transfer session removing on signoff notify.
1078 Affected file irssi/src/silc/core/silc-servers.c.
1080 * Added the SilcClientFileError to be returned in the monitor
1081 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1082 Affected file lib/silcclient/silcapi.h.
1084 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1086 * Fixed a crash in silc_client_ftp_free_sessions and
1087 silc_client_ftp_session_free_client. Affected file
1088 lib/silcclient/client_ftp.c.
1090 * Added `disabled' field in the SilcChannelEntry in the server
1091 to indicate if the server entry is disabled. Affected file
1092 silcd/idlist.h, silcd/command[_reply].c.
1094 * SILC server adds now /var/run/silcd.pid everytime it is
1095 started. Affected file silcd/silcd.c.
1097 * Added silc_server_packet_send_clients to send a packet to
1098 the provided table of client entries. Affected file
1099 silcd/packet_send.[ch].
1101 * Fixed a crash in client resolving in client_prvmsg.c in
1102 client library. Affected file lib/silcclient/client_prvmsg.c.
1104 * Do not actually remove the client directly from ID cache
1105 during SERVER_SIGNOFF, but invalidate it. This way we
1106 preserve the WHOWAS info for the client. Affected file
1107 silcd/server_util.c.
1109 * Fixed SERVER_SIGNOFF notify handling in the server. The
1110 server is now able to process incoming SERVER_SIGNOFF notify
1111 for a server that it doesn't even know about. It will remove
1112 the clients provided in the notify. Affected file
1113 silcd/packet_receive.c.
1115 * Check for partial packet in data queue after every packet that
1116 was found from the queue. Return and wait for more data if
1117 there is partial data in queue. Affected file is
1118 lib/silccore/silcpacket.c.

1135 irssi/src/fe-common/silc/module-formats.[ch].
1137 * Wrote a help file for FILE command.
1139 * Added silc_rng_global_get_byte_fast to get not-so-secure
1140 random data as fast as possible. Random data is read from
1141 /dev/urandom if available and from the SILC RNG if not
1142 available. It is used in padding generation. Affected file
1143 lib/silccrypt/silcrng.[ch].
1145 * All packets in client library are now processed synchronously.

1158 * Assure that silc_client_notify_by_server_resolve does not
1159 resolve the client information multiple times. If it cannot
1160 be found by the first it cannot be found at all. Affected
1161 file lib/silcclient/client_notify.c.
1163 * Fixed WHOWAS command reply calling. Affected file
1164 lib/silcclient/command_reply.c.
1166 * Removed all references to silc_idlist_get_client from the
1167 Irssi SILC client since that call is internal call used by
1168 the library. The Irssi SILC client will use now client
1169 retrieval functions found in silcapi.h.
1171 * Fixed a bug in resolving nickname info before sending
1172 private message. It used freed memory. Affected file
1173 irssi/src/silc/core/silc-servers.c.

1194 * Added silc_net_localip to return local host's IP address.
1195 Affected file lib/silcutil/silcnet.[ch].
1197 * If key exchange or rekey protocol is active for a connection
1198 parse all packets syncronously since there might be packets
1199 in packet queue that we are not able to process without first
1200 processing packets before them. Affected file silcd/server,
1201 lib/silcclient/client.c.
1203 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1204 whether library should continue processing the packet.
1205 Affected file lib/silccore/silcpacket.h.

1251 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1252 is incomplete and is being resolved, it won't be resolved
1255 Make sure also that USERS command reply does not resolve
1256 twice information. Affected file is
1257 lib/silcclient/command_reply.c.
1259 Make sure that silc_client_get_clients_by_list does not
1260 resolve twice same information.
1262 * Check for valid client->id in the silc_server_free_client_data.
1263 Affected file silcd/server.c.
1265 * Fixed /GETKEY nick@server not to crash if the server entry
1266 is not found. Affected file lib/silcclient/command.c.
1268 * Fixed the silc_server_check_cmode_rights to check the
1269 requested modes correctly. Affected file silcd/command.c.

1276 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Call the silc_server_udpate_servers_by_server in the
1279 primary router that comes back online in the backup resuming
1280 protocol. Otherwise it routes packets wrong. Affected file
1281 silcd/server_util.[ch], silcd/server_backup.c.
1283 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1286 lib/silcutil/silcbuffmt.[ch].
1288 * Redefined the SILC packet header to include the padding
1289 length. Affected file lib/silccore/silcpacket.[ch].
1291 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1292 length for maximum padding up to 128 bytes). Affected
1293 file lib/silccore/silcpacket.h.
1295 * Removed all backwards support for old 0.5.x MAC thingies.
1296 The SILC packet header change makes it impossible to be
1297 backwards compatible.
1299 * Send the ENDING packet with timeout in the backup resuming
1300 protocol. This is to assure that all routers has connected
1301 to the primary router. Affected file silcd/server_backup.c.
1303 * Changed the RNG to take the first IV from random data. It
1304 used to take it from zero actually. Changed the RNG also
1305 to use /dev/urandom during session. /dev/random is used
1306 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1308 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Changed the SILC packet header to have the first two bytes
1311 (the packet length) encrypted. Affected files aroung the
1312 code tree, lib/silccore/silcpacket.[ch]. Removed the
1313 SilcPacketCheckDecrypt callback. It is not needed anymore
1314 since the silc_packet_receive_process will determine now
1315 whether the packet is normal or special.
1317 * Implemented the unidirectional MAC keys. Affected files
1318 lib/silcske/silcske.c, silcd/protocol.c and
1319 lib/silcclient/protocol.c.
1321 * Implemented the packet sequence number to the MAC computation.
1322 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1323 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1324 lib/silcclient/protocol.c.
1326 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Allow backup router to announce servers. All servers
1329 announced by backup router are added to the global list
1330 automatically. Update hte server's socket to our primary
1331 router also when backup router announces a server.
1332 Affected file silcd/packet_receive.c.
1334 * Do not update the client->router in the function
1335 silc_server_udpate_clients_by_server if the client is on
1336 global list. We might fail to find any specific server
1337 for locally connected clients and local cell clients. They
1338 should still use the `from' and not `to' as client->router.
1339 This fixes backup router resuming protocol. Affected file
1340 silcd/server_util.c.
1342 * Decrease channel statistics count only if the channel
1343 deletion worked. Affected files are silcd/server.c and
1344 silcd/server_util.c.
1346 * Added silc_server_update_servers_by_server to update origin
1347 of all server entries. Used during backup router protocol.
1348 Affected files silcd/server_util.[ch], silcd/server.c. and
1349 silcd/backup_router.c.
1351 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1352 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1353 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1354 lib/silccrypt/silchmac.c.
1356 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Assure that router cannot reroute the same channel message
1359 to the sender. Affected file silcd/packet_receive.c.
1361 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Made better checks that the channel message is not sent
1364 to the router it came from. Affected file is
1365 silcd/packet_send.c. Fixed memory leak too.
1367 * Announce informations for incoming router connection, but
1368 only after checking if it is replaced by backup router.
1369 Affected file silcd/packet_receive.c.
1371 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1373 * Fixed the backup resuming protocol to work in multiple
1374 router environment. Affected file silcd/server_backup.c.
1376 * Route packet only to one router in the function
1377 silc_server_packet_send_to_channel. Affected file is
1378 silcd/packet_send.c.
1380 * Fixed silc_server_send_notify_dest to set the broadcast
1381 flag. Fixed the silc_server_send_notify_topic to actually
1382 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1383 Affected file silcd/packet_send.c.
1385 * Changed the SFTP Filesystem interface. Changed the
1386 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1387 the filesystem operation function. The SilcSFTPFilesystem
1388 is now a context that is allocated by all filesystem allocation
1389 functions and it already includes the operations structure
1390 and filesystem specific context. It is given as argument
1391 now to the silc_sftp_server_start. This made the interface
1392 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1393 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1395 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1397 * Changed the backup router adding and getting interfaces
1398 in the server. The router that will be replaced by the
1399 specified backup router is now sent as argument. Affected
1400 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1403 * Added silc_net_addr2bin_ne to return the binary form of
1404 the IP address in network byte order. Affected files
1405 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1407 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Check for existing server ID in silc_server_new_server
1410 and in silc_server_connect_to_router_final and remove the
1411 old entry if it exists. Affected file silcd/packet_receive.c,
1414 * Send the channel message always to only one router, either
1415 in upstream or downstream. Affected file is
1416 silcd/packet_send.c.
1418 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Wrote the definition of the backup resuming protocol to the
1421 protocol specification.
1423 * Removed one redundant channel key generation from normal
1424 server during joining procedure. Removed one redundant
1425 channel key sending from server to router during joining
1426 procedure. Affected file silcd/command.c.
1428 * Made minor bugfixes to the backup router resuming protocol.
1429 Affected file silcd/server_backup.c, server.c.

1434 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1437 * Implemented the backup resuming protocol that is used to
1438 resume the primary router position in the cell after the
1439 primary router comes back online. Affected files
1440 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1441 and silcd/server_util.[ch].
1443 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Sleep two (2) seconds after sending QUIT command to server.
1446 Affected file lib/silcclient/command.c.
1448 * Assure that if outgoing data buffer is pending do not force
1449 send any data. Affected file silcd/packet_send.c.
1451 * Assure that if outgoing data buffer is pending do not force
1452 send any data. Affected file lib/silcclient/client.c.
1454 * Implemented the backup router support when the primary router
1455 goes down. The servers and routers can now use the backup
1456 router as new primary router without loosing connectivity.
1458 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1460 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1461 in the server to indicate disabled entry. All data read
1462 from the connection will be ignored and no data is sent
1463 for entry that is disabled. Affected files are
1464 silcd/idlist.h, silcd/server.c.
1466 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1468 * Created SFTP client and server test programs in the
1469 lib/silcsftp/tests directory.
1471 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Implemented memory filesystem (virtual filesystem) for
1474 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1477 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Implemented the SFTP (SSH File Transfer Protocol) to the
1480 lib/silcsftp. It includes SFTP client and SFTP server
1483 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1485 * Moved lib/silccore/silcprotocol.[ch] to the
1486 lib/silcutil library.
1488 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1489 take variable argument list pointer as argument. Affected
1490 file lib/silcutil/silcbuffmt.[ch].
1492 * Added silc_buffer_set function that is used to set data
1493 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1494 Affected file lib/silcutil/silcbuffer.h.
1496 * Changed various routines in the core library to use the new
1497 silc_buffer_set instead of allocating new buffer only for
1500 * Added 64-bit value formatting and unformatting support to the
1501 silc_buffer_[un]format routines. Affected file is
1502 lib/silcutil/silcbuffmt.[ch].
1504 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1505 to includes/bitmove.h.
1507 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1509 * Fixed channel user mode saving in client library. Affected
1510 file lib/silcclient/command[_reply].c.
1512 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Defined the file transfer to the SILC Protocol. Added
1515 new packet type SILC_PACKET_FTP and defined File Transfer
1516 Payload. The mandatory file transfer protocol is SFTP
1517 (SSH File Transfer Protocol). Affected file in addition
1518 of the internet draft is lib/silccore/silcpacket.h.
1520 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1521 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1522 is used as part of backup router protocol when the primary
1523 router of the cell is back online and wishes to resume
1524 the position as primary router.
1526 * Redefined the MAC generation keys in the protocol. The
1527 same key is not used anymore in both direction. Both
1528 direction will now use different keys for sending and
1529 receiving. This fixes a potential security flaw. This
1530 change causes incompatibilities in the protocol.
1532 * Redefined also the MAC computation from the packet.
1533 An packet sequence number is now added to the MAC
1534 computation. This prevents possible replay attacks against
1535 the protocol. This change too causes incompatibilities
1538 Added `sequence' field to the SilcPacketContext to hold
1539 the current sequence number for the packet.
1541 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1543 * Added `created' field to the SilcIDListData in the file
1544 silcd/idlist.h to indicate the time when the entry was
1547 * Added `created' field to the SilcChannelEntry too. Affected
1548 file silcd/idlist.h.
1550 * Added `creation_time' aguments to all the announcement functions
1551 in the server. If it is provided then only the entries that
1552 was created after the provided time frame are actually
1553 announced. Affected file silcd/server.[ch].
1555 * The protocol says that the Channel ID's IP address must be
1556 based on the router's IP address. Added check for this in
1557 the silc_server_new_channel when processing incoming New Channel
1558 Payload. Affected file silcd/packet_receive.c.
1560 * Print out the correct version with --version in SILC client.
1561 Affected file irssi/src/silc/core/silc-core.c.
1563 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Fixed WHOWAS command to check for completnes of the client
1566 entry always, not just when the command is coming from client.
1567 Affected file silcd/command.c.
1569 * Added new function silc_server_packet_queue_purge to purge the
1570 outgoing data queue to the network. After the function returns
1571 it is guaranteed that the outgoing packet queue is empty.
1572 Affected file silcd/packet_send.[ch].
1574 * Purge the outgoing packet queue in the rekey protocol's final
1575 callback to assure that all rekey packets go to the network
1576 before quitting the protocol. Affected file silcd/server.c.
1578 * Added silc_client_packet_queue_parse as similar function as
1579 in server to the client library. The affected file is
1580 lib/silcclient/client.c.
1582 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Splitted silcd/server.c and created silcd/server_util.[ch]
1585 for utility functions.
1587 * Added new socket flag SILC_SF_DISABLED to indicate that the
1588 connection is open but nothing can be sent to or received from
1589 the connection. Affected file lib/silcutil/silsockconn.[ch].
1590 The checking for disabled socket is checked in the low level
1591 silc_socket_write and silc_socket_read functions.
1593 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Allow only nicknames and channel names that fits into the
1596 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1598 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * When processing JOIN command reply in server check that if
1601 the channel exists in our global list we'll move it the local
1602 list. Affected file silcd/command_reply.c.
1604 * Fixed the check whether client is joined on the channel already
1605 in JOIN command. Affected file lib/silcclient/command.c.
1607 * Fixed the JOIN command reply to check whether the channel
1608 already exists. Affected file lib/silcclient/command_reply.c.
1610 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Added silc_ske_status_string to map the SKE error numbers
1613 to readable strings. The affected files are
1614 lib/silcske/silcske[_status].[ch].
1616 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Do not show the private channels on the WHOIS channel list
1619 as it is not allowed by the protocol. The affected file is
1622 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1624 * Assure that the packet length digged from the actual packet
1625 is something sensible in the silc_packet_decrypt_rest_special
1626 in lib/silccrypt/silcpacket.c.
1628 * Free and NULL the allocated pointer in silc_hmac_alloc if
1629 the HMAC allocation fails. The affected file is
1630 lib/silccrypt/silchmac.c.
1632 * Print the selected security properties to the log files in
1633 the server. Affected file silcd/protocol.c.
1635 * Add SKE's reference counter even if calling the completion
1636 callback manually. Otherwise it goes negative, although it
1637 does not cause any problems. The affected file is
1638 lib/silcske/silcske.c.
1640 * Remove the client entry with short timeout after giving the
1641 KILL command. Affected file lib/silcclient/command.c.
1643 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1644 case all found clients are already disconnected (WHOWAS would
1645 found them) in the server. Affected file silcd/command.c.
1647 * Update the last_receive (time of last data received) to be
1648 updated only when received private or channel message so that
1649 the idle time showed in WHOIS makes more sense.
1651 * Added boolean field `valid' in to the SilcClientEntry in the
1652 client library to indicate whether the entry is valid or not.
1653 This fixes the nickname change bug on channel when changing
1654 the nickname to be same than the old (like nick to Nick) the
1655 nickname formatter doesn't set the new nick anymore to Nick@host.
1656 Affected file lib/silcclient/idlist.[ch].
1658 * Now actually fixed the nickname changing on disconnection.
1659 Added new function silc_change_nick to the Irssi SILC Client.
1660 Affected file irssi/src/silc/core/client_ops.c,
1661 irssi/src/silc/core/silc-nicklist.[ch].
1663 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Check that the public key exists in the GETKEY command before
1666 trying to encode it. Affected file silcd/command.c.
1668 * Print some notifications on received public keys with GETKEY
1669 command in the Irssi SILC Client. Affected files are
1670 irssi/src/fe-common/silc/module-formats.[ch],
1671 irssi/src/silc/core/client_ops.c.
1673 * Use IDENTIFY command to resolve the server information in the
1674 GETKEY command instead of INFO command. Affected file
1675 lib/silcclient/command.c.
1677 * All command reply functions in the client library now calls
1678 the pending command reply callbacks even if an error has
1679 occurred. The server has done this a long time and now it was
1680 time to move the client library to this as well. Now all
1681 errors can be delivered back to the pending command reply
1682 callbacks if necessary. Affected files are
1683 lib/silcclient/command[_reply].[ch].
1685 * Change the nickname on disconnection back to the username
1686 because in reconnect the server will enforce it to it anyway.
1687 Affected file irssi/src/silc/core/silc-servers.c.
1689 * Fixed a config file parsing bug in the Irssi SILC client.
1690 Affected file irssi/src/silc/core/clientconfig.c.
1692 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * When printing the channel mode on JOIN, verify that the
1695 channel key and channel's HMAC are valid. Affected file
1696 irssi/src/silc/core/client_ops.c.
1698 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1700 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1701 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1702 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1704 * Removed channel key rekey task deleting from the function
1705 silc_server_save_channel_key. Affected file silcd/server.c.
1706 Added explicit timeout task context instead that is used to
1707 delete the task if we are registering a new task before the
1708 new task has elapsed.
1710 * When channel key rekey occurs the client library now saves
1711 the old channel key for a short period of time (10 seconds) and
1712 is able to use it in case some is still sending channel
1713 messages encrypted with the old key after the rekey. Affected
1714 file lib/silcclient/[idlist.h|client_channel.c].
1716 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Added check to the silc_server_new_id_real to not accept
1719 new ID if it is the sender's own ID. Affected file is
1720 silcd/packet_receive.c.
1722 * Assure that we do not announce ourself or the one we've
1723 sending our announcements when we're router and are announcing
1724 servers to our primary router. Affected file silcd/server.c.
1726 * Fixed silc_server_command_identify_check_client to assemble
1727 correct WHOIS packet. It send corrupted WHOIS packet and
1728 caused problem with router to router connections. Affected
1729 file silcd/command.c.
1731 Fixed also silc_server_command_whois_check the same way
1732 as for the IDENTIFY command.
1734 * Added new SilcIDListStatus to the server in the SilcIDListData
1735 structure. The status now includes the current status of
1736 the entry (like registered, resolved etc.). Affected file
1737 silcd/idlist.[ch]. Defined a bunch of different status types
1738 as well. This replaced the old boolean registered field as well.
1740 Added resolve_cmd_ident field to the SilcClientEntry structure
1741 too so that if the entry is for example being resolved so
1742 another command may attach to the same pending command reply
1743 without requiring to resolve the same entry again. This concept
1744 should optimize the WHOIS and the IDENTIFY resolving under
1745 heavy load by taking away unnecessary resolving for entries
1746 that are being resolved already.
1748 Added support for adding multiple pending commands for one
1749 command idenfier. Affected file silcd/command[_reply].[ch].
1751 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1752 before deleting the data. Otherwise the hash table will have
1753 freed data in comparison functions. Affected file is
1754 silcd/command_reply.c.
1756 * Fixed silc_idlist_replace_client_id to add the new entry to
1757 the cache with NULL nickname. Otherwise there will be invalid
1758 memory as the nickname after the nickname is freed. Affected
1759 file silcd/packet_receive.c.
1761 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1762 saved into wrong slots because the previous number of entries
1763 was not taken into account. Affected file silcd/idlist.c.
1764 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1766 * If we are router and we receive JOIN notify to a channel that
1767 does not have any users then notified client is marked as the
1768 channel founder, as it is it. The affected file is
1769 silcd/packet_receive.c
1771 * Added to the extended hash table API's table_del_*ext functions
1772 the destructor as argument too, so that the caller can decide
1773 which destructor to use or whether to use destructor at all.
1774 Affected file lib/silcutil/silchashtable.[ch].
1776 * Fixed ID Cache purging. It actually deleted the entries from
1777 the hash table after the data was freed. The hash table ended
1778 up comparing freed memory. The affected file is
1779 lib/silccore/silcidcache.c.
1781 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Fixed Irssi SILC client's KILL command's HELP syntax.
1785 * The USERS command now resolves the detailed user information
1786 if the userinfo field is missing. Affected file is
1787 lib/silcclient/command_reply.c.
1789 * Do not print error in silc_file_read if the read file does
1790 not exist. Just silently return NULL. Affected file is
1791 lib/silcutil/silcutil.c.
1793 * Fixed the silc_log_output to not wine about NULL filename
1794 and to not create some bogus " " filename. Affected file is
1795 lib/silcutil/silclog.c.
1797 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Fixed various printing bugs on the user interface in the
1800 Irssi SILC Client. Minor changes that were forgotten from
1803 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1805 * Fixed the configure.in.pre and the compilation and distribution
1806 environment to support the new autoconf 2.52. That version is
1807 now required to compile the CVS trunk.
1809 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1811 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1812 to generally parse user@fqdn format strings. Affected file
1813 lib/silcutil/silcutil.c.
1815 * Added nickname_format and nickname_force_format fields to the
1816 SilcClientParams structure. The first one defines the format
1817 for the nicknames that the library will enforce if the receives
1818 multiple same nicknames. The second one is boolean value and
1819 can be used to force the library to always enforce the format
1820 to the nicknames regardles whether there are multiple nicknames
1821 or not. This configurable formatting was employed to flexibly
1822 support accessing multiple nicknames from the user interface.
1823 The userinterface can now set the nicknames to what ever format
1824 they prefer. Affected file lib/silcclient/silcapi.h.
1826 Added function silc_client_nickname_format to the file
1827 lib/silcclient/idlist.c. It performs the nickname formatting.
1829 Added new field `hostname´ to the SilcClientEntry context.
1830 It holds the hostname of the client. Affected file is
1831 lib/silcclient/idlist.h.
1833 * Irssi SILC Client sets the nicknames in nick@hostn format.
1834 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1835 irssi/src/silc/core/silc-core.c.
1837 The WHOIS printing now also shows both the real nickname and
1838 the formatted nickname so that user knows how to access the
1839 user if there are multiple same nicknames cached. Affected
1840 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1841 printing formatting too to take the hostname now as a separate
1842 argument. The Affected file is
1843 irssi/src/fe-common/silc/modules-formats.[ch].
1845 * Changed the silc_client_get_clients_local to accept the formatted
1846 nickname as argument. It accepts the real nickname too but the
1847 formatted nickname can be used to find the true entry from
1848 multiple entries. Affected file lib/silcclient/silcapi.h and
1849 lib/silcclient/idlist.c.
1851 * Added nickname_format_parse field to the SilcClientParams.
1852 It is a callback function provided by the application to parse
1853 the nickname out of the formatted nickname string. The library
1854 calls it to get the nickname from the formatted string. Since
1855 the application generally knows better the format of the nickname
1856 string it parses it instead of the library, even though library
1857 encodes the formatted string. If the callback function is not
1858 provided then the library will use the string as is. The
1859 affected file is lib/silcclient/silcapi.h.
1861 * All the nickname strings passed to the client library in
1862 commands are now expected to be formatted nickname strings.
1863 If the command does not support the formatted nickname string
1864 it will assume that the sent string is the actual nickname.
1865 Affected file lib/silcclient/command.c.
1867 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Added public key authentication support to OPER and SILCOPER
1870 commands in the client library. Affected file is
1871 lib/silcclient/command.c.
1873 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Changed the get_auth_methdod client operation to be asynchronous.
1876 It can be async if the application resolves the authentication
1877 method from the server during the negotiation. Added new
1878 SilcGetAuthMeth completion callback that the application will
1879 call after resolving the authentication method.
1881 Added function silc_client_request_authentication_method that
1882 the application can use to resolve the authentication method
1883 from the server. Added also SilcConnectionAuthRequest callback
1884 that the library will call after the server has replied. The
1885 application can call this function if it does not know the
1886 current authentication method.
1888 Affected files are lib/silcclient/client.c and
1889 lib/silcclient/silcapi.h.
1891 * The Irssi SILC client now automatically resolves the authentication
1892 method incase any configuration information is not present (and
1893 currently there never is). The affected file is
1894 irssi/src/silc/core/client_ops.c.
1896 * Fixed public key authentication from the client library.
1897 Affected file lib/silcclient/protocol.c. Changed also the
1898 protocol specification about the public key authentication in
1899 the connection authentication protocol. The actual data to be
1900 signed is now computed with a hash function before signing.
1902 * Fixed the public key authentication from the server as well.
1903 Affected file silcd/protocol.c.
1905 * Removed the mlock()'s from the memory allocation routines.
1906 Affected file lib/silcutil/silcmemory.c. The ./configure does
1907 not check anymore for the mlock(). Affected file is
1910 * Fixed USERS command in server to allow the execution of the
1911 command for private and secret channels if the client sending
1912 the command is on the channel. Affected file silcd/command.c.
1914 * Fixed silc_client_get_clients_local to return the clients
1915 count correctly. It could return wrong value. Affected file
1916 lib/silcclient/idlist.c.
1918 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1921 types. The assembler optimizations seemed not to like 64-bit
1922 data types. The assmebler optimizations thus are now enabled
1923 also for BSD systems as opposed to only enable them for Linux.
1925 * Do not check for threads at all on BSD systems. Affected
1926 file configure.in.pre.
1928 * Removed -n and -h options from the Irssi SILC Client since
1929 they are not used in silc.
1931 * Fixed the prime generation to assure that the first digit
1932 of the generated random number is not zero since our conversion
1933 routines does not like number strings that starts with zero
1934 digit. If zero digit is seen the random number is regenerated.
1935 This caused some corrupted RSA keys when the zero first digit
1936 was met. Affected file lib/silcmath/silcprimegen.c.
1938 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1940 * Fixed WIN32 configuration in the ./configure script.
1941 Fixed to include xti.h on environments that has it.
1942 Patches by Carsten Ilchmann and andrew.
1944 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Changed the silc_id_create_client_id to be collision
1947 resistant. It is now assured that there cannot be created
1948 two same client ID's. I suspect that some weird bugs in
1949 the server were actually caused by duplicate Client IDs.
1950 Affected file silcd/serverid.[ch]. A router receiving
1951 new ID now also assures and informs the sending server
1952 if the ID caused collision.
1954 * Changed the silc_id_create_channel_id to also assure that
1955 there are no collisions.
1957 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Statement about ignoring the Mutual Authentication flag when
1960 performing rekey with PFS was a bit misleading. It is ignored
1961 if it was set in the initial negotiation, it cannot be even
1962 set in the rekey. Fixed in the ke-auth draft. Started the
1963 new versions of the protocol drafts in the doc/.
1965 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Fixed a bug in silc_client_command_identify_save when saving
1968 new channel information. The channel name was no duplicated
1969 and caused crash on exit. Affected file is
1970 lib/silcclient/command_reply.c.
1972 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Fixed the getkey command handling in the server. Send just
1975 empty OK reply to the sender if the key could not be fetched
1976 (but everything else was ok, like the key just was not available).
1977 Changed the public key parameter to optional in the protocol
1978 specs so that empty OK reply can be sent. Affected file
1981 Added a message to Irssi SILC client to tell to user if the
1982 server did not return a public key.
1984 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Fixed a channel key regeneration bug. It registered new
1987 timeout tasks exponentially until all system resources were
1988 used. Affected file silcd/server.c.
1990 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * Added the SILC Document generator to the scripts/silcdoc.
1993 It can be used to generate the Toolkit Reference Manual out
1994 of the source tree. Internally it will also use the RoboDoc
1995 generator now imported in util/robodoc.
1997 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Added couple of return's in rekey protocol if error orccurred
2000 during the protocol. The execution must be terminated.
2001 Affected file silcd/protocol.c. Also, terminate the protocol
2002 always with timeout.
2004 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * The client's Client ID was created initally from the wrong
2007 nickname (it could have been in format nick@host) in the
2008 silc_server_new_client. Affected file silcd/packet_receive.c
2010 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Added some SILC_LOG_ERROR's to various error conditions
2013 if client could not be added to ID cache. Affected files
2014 silcd/packet_receive.c and silcd/server.c.
2016 * When client's sock->user_data is freed, NULL also the
2017 client->router and client->connection pointers. Added check
2018 for these pointers being NULL to various places around the
2019 code. Affected file silcd/server.c.
2021 * Added client->data.registered == TRUE checks to various
2022 places around the code to assure that unregistered client's
2023 are not handled when it is not allowed. Affected file
2026 * Added `bool registered' fields to all
2027 silc_idlist_[server|client]_get_* routines to indicate whether
2028 the fetched client needs to be registered or not. Affected
2029 file silcd/idlist.[ch].
2031 * Add your own entry as registered to the ID cache in the
2032 server. Affected file server.c.
2034 * Fixed a bug in silc_server_new_server. The SilcServer was
2035 set as the new server's context instead of SilcServerEntry.
2036 This naturally caused some weird bugs.
2038 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Do not delete the channel rekey task when adding it
2041 for in silc_server_create_channel_key.
2043 * Changed the silc_server_create_channel_key to return
2044 TRUE or FALSE to indicate the success of the channel key
2047 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Fixed MSVC++ project files and added missing files to
2050 Makefiles under win32/.
2052 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2054 * Do not add TCP_NODELAY flag if the operating system
2055 does not have it defined. Affected files are
2056 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2058 * Fixed buffer overflow from Irssi SILC Client. Affected
2059 file irssi/src/fe-common/core/themes.c.
2061 * Fixed double free in client library in the file
2062 lib/silcclient/client.c when disconnecting from server.
2064 * Applied double free patch from cras to Irssi SILC client.
2065 Affected files irssi/src/core/[modules/expandos].c
2067 * Fixed the disconnection handling to Irssi SILC Client.
2068 The application must call silc_client_close_connection
2069 in ops->connect client operation in case of failure of
2070 the connection. Affected file is
2071 irssi/src/silc/core/client_ops.c.
2073 * Do not set sock->protocol to NULL in the function
2074 silc_client_close_connection after executing the protocol's
2075 final callback since the sock might not be valid anymore.
2076 Affected file lib/silcclient/client.c.
2078 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2080 * Do not enable SILC_THREADS if the linking with libpthread
2081 did not happen. Affected file configure.in.pre.
2083 * Added notion to protocol specification that server must
2084 verify the sent authentication payload with CMODE when
2085 setting the channel founder key. Implemented it to the
2086 server. Affected file silcd/command.c.
2088 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Added _EXTRA_DIST SILC distribution variable to the
2091 distributions file. It is used to conditionally add extra
2092 files or directories to the specific distribution. Affected
2093 files ./prepare, Makefile.am.pre and distributions.
2095 Removed the `_' from the start of the distribution names.
2098 * Added README.WIN32 for instructions to compile the Toolkit
2101 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2103 * Fixed a double free in disconnection in the server. Affected
2104 file is silcd/server.c.
2106 * Fixed the lib/silcske/groups.c to work now also with GMP
2107 MP library. The string conversion did not work when using
2108 specific base and the base is indicated in the string as well.
2110 * Created win32/ directory which now includes MSVC++ specific
2111 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2112 It will appear only in the toolkit distribution
2114 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Changed the key material distribution function in case when
2117 the hash output is too short. The data is now concatenated
2118 a bit differently than it used to. Made the change to the
2119 SKE protocol specification.
2121 * Added better GMP detection to configure.in.pre. A patch
2124 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2126 * Fixed a minor bug in SKE that might cause some problem on
2127 some platforms. Affected file lib/silcske/silcske.c.
2129 * Added the cookie checking for initiator in the SKE. It checks
2130 that the responder returns the sent cookie unmodified. The
2131 affected file is lib/silcske/silcske.c. Added new SKE
2132 error type INVALID_COOKIE that can be sent during the
2133 negotiation. Fixed some memory leaks as well.
2135 * Added the "invalid cookie" error message to Irssi SILC client's
2138 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Added `task_max' field to the SilcClientParams to indicate
2141 the maximum tasks the scheduler can handle. If set to zero,
2142 default values are used. Affected file lib/silcclient/silcapi.h.
2144 * Fixed memory leaks in silc_client_close_connection. Affected
2145 file lib/silcclient/client.c.
2147 * Added silc_client_del_client_entry to client library to free
2148 all memory of given client entry. Affected file is
2149 lib/silcclient/idlist.[ch].
2151 * Added new functions silc_client_del_channel and
2152 silc_client_del_server to delete channel and server entries.
2153 Affected file lib/silcclient/[silcapi.h/idlist.c].
2155 * Removed silc_client_del_client_by_id from silcapi.h.
2157 * Fixed the INFO command to return the server's own info
2158 correctly when querying by Server ID. Affected file is
2161 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Removed the non-blocking settings in WIN32 code in the
2164 silc_sock_[read/write] and added SleepEx instead. Affected
2165 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2166 of input data is now checked with FIONREAD and ioctlsocket.
2168 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2170 * Call silc_schedule_task_del_by_context in the
2171 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2172 Affected file lib/silccore/silcprotocol.c.
2174 * Call silc_protocol_cancel for active protocols in the
2175 silc_server_close_connection if the funtion
2176 silc_server_free_sock_user_data has not been called.
2177 Affected file silcd/server.c.
2179 * Generic tasks cannot be deleted using the del_by_fd
2180 task deleting function since generic tasks does not match
2181 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2183 * Added a notion to SILCOPER help file that the SILCOPER works
2184 only on router server, not on normal server.
2186 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Added for WIN32 support for the new scheduler as well.
2189 Affected file lib/silcutil/win32/silcwin32schedule.c.
2191 * Fixed the SHA1 implementation to work on various platforms.
2193 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2196 API. It is part of the scheduler now. Everything else is
2197 as previously but some functions has changed their names.
2198 Checkout the lib/silcutil/silcschedule.h for the interface.
2199 Updated all applications to use the new interface. Affected
2200 files are lib/silcutil/silcschedule.[ch].
2202 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Found a bug in the SKE implementation. The HASH value,
2205 specified by the protocol, was not computed correctly. The
2206 public key of the responder was not added to the computation
2207 even though it is mandatory. Affected file lib/silcske/silcske.c.
2208 This unfortunately causes incompatibilities with older
2209 clients and servers.
2211 * Added WIN32 specific network init and uninit functions:
2212 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2213 the Winsock2. Affected file lib/silcutil/silcnet.h and
2214 lib/silcutil/win32/silcwin32net.c.
2216 * Set the socket always to nonblocking mode on WIN32 after
2217 reading data or writing data. Affected file is
2218 lib/silcutil/win32/silcwin32sockconn.c.
2220 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2222 * Fixed various compilation problems under WIN32. Affected
2223 files lib/silcutil/win32/silcwin32thread.c and
2224 lib/silcutil/win32/silcwin32schedule.c.
2226 * Removed all _internal.h #includes from public header
2227 files. Internal headers must never be included from
2230 Removed also the lib/silcske/payload_internal.h file.
2232 * All include files that may be needed (public and some others
2233 included by the public headers) by application developers are
2234 now copied to the ./includes directory. It does not copy any
2235 internal headers. Affected file Makefile.defines.pre and all
2236 Makefile.am's under lib/ and subdirs.
2238 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2240 * Do not change the ~/.silc directory's permissions automatically.
2241 Affected file irssi/src/silc/core/clientutil.c.
2243 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2245 * Do not cancel the protocol in silc_server_close_connection
2246 it might cause recursion. Now cancelled in the function
2247 silc_server_free_sock_user_data. Affected file silcd/server.c.
2249 * Fixed the silc_server_remove_clients_by_server to regenerate
2250 the channel keys correctly finally. Added also new function
2251 silc_server_remove_clients_channels to actually do it.
2252 Affected file silcd/server.c.
2254 * Fixed the silc_server_new_channel to not crash by giving
2255 wrong router to the new channel. Affected file is
2256 silcd/packet_receive.c.
2258 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2260 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2261 which is given as argument to the silc_client_alloc now.
2262 It can be used to configure the client and set various parameters
2263 that affect the function of the client.
2265 * The USERS command in server did not check whether the channel
2266 is private or secret. Affected file silcd/command.c.
2268 * Added new argument to the USERS command in protocol specification.
2269 The USERS command now can take the channel name as argument
2270 as well. Added support for this in client and server and
2271 updated the protocol specs.
2273 * Completed the GETKEY command in client. It can be now used
2274 to fetch also servers public key not only some clients.
2275 Affected files lib/silcclient/command[_reply].c.
2277 * Added silc_client_get_server to return server entry by the
2278 server name. Affected files lib/silcclient/silcapi.h and
2281 * Redefined the IDENTIFY command in protocol specification to be
2282 more generic. It now can be used to query information about
2283 any entity in the SILC Network, including clients, servers and
2284 channels. The query may be based either the entity's name
2285 or the ID. Added support for this in both client and server.
2287 Affected files silcd/command.c and lib/silcclient/command.c
2288 and command_reply.c.
2290 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2291 the _from_client and _from_server functions. Affected file
2294 * Added silc_client_get_channel_by_id_resolve to the file
2295 lib/silcclient/silcapi.h to resolve channel information by
2296 its ID. Added also silc_client_get_channel_by_id that
2297 does not resolve it from the server.
2299 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Added SilcServerEntry context into the client library
2302 to represent one server. The INFO command now allocates
2303 these to save the resolved server info. For now on the
2304 client library will also keep information about servers,
2305 connected and resolved with INFO.
2307 The INFO command now allocates the SilcServerEntry context
2308 and saves the server info there. The COMMAND_REPLY in
2309 the INFO now returns the parameters to application in
2310 same order as defined in the protocol specification.
2312 The entries are cached in the client->server_cache.
2314 * The INFO command is now issued after received the Client ID
2315 from the server. Affected file lib/silcclient/client.c.
2317 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2318 to the application as the mode changer might be server.
2319 It is guaranteed that NULL is not returned anymore to the
2320 application. Affected file lib/silcclient/client_notify.c.
2322 The ID Type is now also passed to the application so that
2323 it can check whether the returned entry is SilcClientEntry
2326 Added new function silc_client_get_server_by_id to return
2327 the server entry by ID. Affected files are the
2328 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2330 * Do not create the channel in the Irssi SILC Client when issuing
2331 the JOIN command but when received the sucessful JOIN command
2332 reply. Otherwise the channel might get created even though we
2333 could not join it. The Affected file is
2334 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2336 * Fixed a channel joining bug in router. The router must also
2337 check the channel modes, invite and ban lists etc. when serving
2338 the JOIN command sent by normal server. Affected file is
2339 silcd/command.c. The router now resolves the client's
2340 information from the server who sent the JOIN command if it
2341 does not know it, and processes the JOIN command only after
2344 * Changed the SilcCommandCb to take new argument; void *context2.
2345 Affected file lib/silccore/silccommand.h
2347 The second argument in the command callbacks in the server now
2348 includes the SilcServerCommandReplyContext if the command was
2349 called as pending command callback from the command reply.
2350 Otherwise it is NULL. When called as pending the status of the
2351 command reply will be checked and if it was erronous the
2352 error will be sent to the original sender of the command.
2353 This way the client always receives the error messages even
2354 though the server was actually the one who received the error
2355 when it resent the command to router, for example. Affected
2356 files silcd/command[_reply].[ch].
2358 * Fixed sending WHOWAS command's error message to client if
2359 the requested client could not be found. It was missing.
2362 * Changed the CMODE and CUMODE commands reply arguments in the
2363 protocol specification. The Channel ID is now sent in both
2364 of the commands to identify the channel. Implemented this
2365 new feature to the client and server. Affected files
2366 lib/silcclient/command_reply.c and silcd/command.c.
2368 * Made better checks for invite and ban lists in the JOIN
2369 command in server. Affected file silcd/command.c.
2371 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * The server now performs the incoming host IP/DNS lookup
2374 using the silc_socket_host_lookup and thus does not block
2375 the server anymore. Affected file silcd/server.c.
2377 * Completed the multi-thread support for SILC Scheduler in
2378 the lib/silcutil/silcschedule.c.
2380 * Fixed the configure.in.pre to detect the pthread correctly
2383 * Fixed a deadlock in silc_task_queue_wakeup in the file
2384 lib/silcutil/silctask.c.
2386 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Added new function silc_schedule_wakeup that is used in
2389 multi-threaded environment to wakeup the main thread's
2390 schduler. It needs to be used when a thread adds a new task
2391 or removes a task from task queues. After waking up, the
2392 scheduler will detect the task queue changes. If threads
2393 support is not compiled in this function has no effect.
2394 Implemented the wakeup mechanism to both Unix and WIN32
2395 systems. Affected files are lib/silcutil/silcschedule.[ch],
2396 lib/silcutil/unix/silcunixschedule.c and the
2397 lib/silcutil/win32/silcwin32schedule.c.
2399 * Added new function silc_task_queue_wakeup to wakeup the
2400 scheduler by the specified task queue. Affected file
2401 lib/silcutil/silctask.[ch].
2403 * The silc_socket_host_lookup_start now wakes up the scheduler
2404 after adding the timeout task. Affected file is
2405 lib/silcutil/silcsockconn.c.
2407 * The silc_socket_host_lookup is synchronous now if the threads
2408 support is not compiled in. However, the callback is still
2409 called asyncronously through the scheduler, anyway. Affected
2410 file lib/silcutil/silcsockconn.c.
2412 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * Added new function silc_socket_host_lookup to perform
2415 asynchronous IP and FQDN lookups for the socket connection.
2416 Affected files lib/silcutil/silcsockconn.[ch].
2418 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2421 that may or may not compile the mutex support in.
2423 Changed the silc_mutex_alloc interface. It allocates the
2424 mutex now to the sent pointer and returns TRUE or FALSE.
2426 Affected file lib/silcutil/silcmutex.h.
2428 * Wrote the SILC Task Queue interface to support multi-threads.
2429 Affected file lib/silcutil/silctask.[ch].
2431 * Wrote the SILC Scheduler to support multi-threads. Affected
2432 file lib/silcutil/silcschedule.c.
2434 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2437 in lib/silcutil/win32/.
2439 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Defined SILC Mutex API and SILC Thread API and implemented
2442 them for Unix. Affected files are
2443 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2444 lib/silcutil/unix/silcunixmutex.c and
2445 lib/silcutil/unix/silcunixthread.c.
2447 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Fixed the silc_server_remove_clients_by_server's channel
2450 key re-generation. The hash table handling was incorrect
2451 and would not work with many channels. Affected file is
2454 * Fixed some memory leaks around the server code.
2456 * Rewrote the silc_server_get_users_on_channel to support IPv6
2457 based Client ID's. Affected file silcd/server.c.
2459 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2460 specification. However, a separate document must be written
2461 to define the detailed signing procedure and the payload
2462 associated with the flag. Defined the flag to the
2463 lib/silccore/silcchannel.h as well.
2465 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Changed the dynamic tables to static size tables in the
2468 lib/silccrypt/silchmac.c.
2470 * Removed GCC dependencies from the code. A patch by cras.
2472 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Do not show the error "Error receiving packet bla bla"
2475 in server if it really was not an error (-2 means that reading
2476 is pending). Affected file silcd/server.c.
2478 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Fixed a possible crash in silc_server_remove_clients_by_server
2481 in silcd/server.c. Fixed there also some memory leaks.
2483 * Fixed the silc_idlist_replace_client_id. It could replace
2484 wrong key in the hash table. Affected file silcd/idlist.c.
2486 * Do not check whether there are global users on the channel
2487 if the channel->global_users is FALSE. Affected functions
2488 silc_server_remove_from_one_channel and
2489 silc_server_remove_from_channels in silcd/server.c. Also,
2490 do not check if the removed client is local as we can be
2491 sure that global client was not removed from the channel
2492 and checking for global users is not needed.
2494 * The silc_server_remove_clients_by_server now re-generates
2495 the channel keys correctly for those channels that had
2496 clients removed from them. Affected file silcd/server.c.
2498 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Found the reason of random crashes in the server. We weren't
2501 ignoring the SIGPIPE signal (which can be sent in write())
2502 and it crashed the server. Affected file silcd/silcd.c.
2504 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Assure that sock->user_data is not NULL in the function
2507 silc_server_packet_send in silcd/packet_send.c.
2509 * Disconnect the remote connection if it could not be added
2510 to any ID lists in the server. The affected file is
2513 * Check in silc_server_packet_send[_real/dest] that the
2514 socket is not disconnecting and ignore the data if it is.
2515 Affected file silcd/packet_send.c.
2517 * Define inline to __inline on native WIN32 compilation.
2518 Affected file includes/silcwin32.h.
2520 * Added some explicit type casts for inline code since MSVC
2521 require them. Affected files lib/silcutil/silcbuffer.h,
2522 lib/trq/silcdlist.h and lib/trq/silclist.h.
2524 * Print warning in log files from now on if the packet
2525 decryption fails. Affected file silcd/server.c.
2527 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Changed the `say' client operation's interface to accept
2530 new `type' argument to indicate the type of the message sent
2531 by the library. The application may filter the library's
2532 messages according the type. The affected file is the
2533 lib/silcclient/silcapi.h.
2535 * Added two new functions to lib/silcclient/silcapi.h:
2536 silc_client_del_client and silc_client_del_client_by_id.
2537 Affected file lib/silcclient/idlist.c.
2539 * Moved the clientincludes.h from includes/ to silc/ and
2540 serverincludes.h from includes/ to silcd/.
2542 * The modes for the CMODE and CUMODE are now passed as
2543 uint32 for application with COMMAND_REPLY. The affected
2544 file is lib/silcclient/command_reply.c.
2546 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * /WHOIS without arguments shows client's own information.
2549 Affected file lib/silcclient/command.c.
2551 * Changed PING to not accept any arguments. The specs
2552 says that client can ping only the connected server so
2553 requiring an argument is not needed. Affected file is
2554 lib/silcclient/command.c.
2556 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Fixed a fatal bug in private message sending and reception
2559 encryption and decryption when using private message keys.
2560 The implementation was incorrect and did not follow the
2561 specification. It causd that some of the message were
2562 lost since it did not use the sending and receiving keys
2563 as the protocol suggests. This has been fixed and will cause
2564 incompatibilities with older clients when sending private
2565 message encrypted with private message keys. Affected files
2566 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2567 and various other in Irssi SILC Client.
2569 Added `responder' boolean argument to the functions
2570 silc_client_add_private_message_key[_ske] to indicate when
2571 the key is added as responder or initiator of the key
2574 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Removed the silc_ske_check_version function and created
2577 a SilcSKECheckVersion callback. Added also a function
2578 silc_ske_set_callbacks that is now used to set all SKE
2579 callbacks. The callback functions are not given to
2580 the SKE functions anymore, but this function is used to
2583 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2585 * Added `silc_version' argument to the silc_client_alloc
2586 to define the version of the application for the library.
2587 The library will use the version string to compare it
2588 against the remote host's (usually a server) version
2589 string. Affected file lib/silcclient/silcapi.h
2591 * Added the KE protocol context to Key Agreement context
2592 in client library so that we can abort the SKE if it
2593 is in process when we get timeout. Affected file is
2594 lib/silcclient/client_keyagr.c.
2596 * Do not resolve the client ID forever if it returns in the
2597 first time that such client does not exist. This was done
2598 for example with private message. Affected file is
2599 lib/silcclient/client_prvmsg.c.
2601 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Do not add regex.h for WIN32. The affected file
2604 includes/silcincludes.h.
2606 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2607 not work yet 100%. It generates the DLL's automatically
2608 when compiling with --with-win32 under cygwin.
2610 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2612 * lib/contrib/regex.c is not compiled on WIN32.
2614 * Added silc_net_get_socket_opt function to the
2615 lib/silcutil/silcnet.h.
2617 * Added includes/silcwin32.h for WIN32 specific includes
2620 * Do not use ptime structure or any of the posix process
2621 functions on WIN32 in lib/silccrypt/silrng.c.
2623 * Added silc_gettimeofday to provide generic function
2624 for struct timeval on all platforms. Added the function
2625 to lib/silcutil/silcutil.h.
2627 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2630 library as they clearly belong there. As a plus side we
2631 can make the actual socket connection routines platform
2634 Added also new generic function silc_socket_read and
2635 silc_socket_write (that used to be silc_packet_[read/write].
2636 The implementation of these are platform specific.
2638 * Added WIN32 specific routines of silc_socket_[read/write]
2639 to lib/silcutil/win32/silcwin32sockconn.c.
2641 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Added preliminary support for native WIN32 compilation under
2644 cygwin (using the -mno-cygwin option for GCC) to the
2645 ./configure.in.pre. The --with-win32 now prepares the
2646 compilation for native WIN32.
2648 * Rewrote the SILC Scheduler interface in the file
2649 lib/silcutil/silcschedule.h. The scheduler is now context
2650 based and does not have anymore any global static scheduler.
2651 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2652 and created lib/silcutil/win32 directory for WIN32 based
2655 * Added Unix specific network routines to the
2656 lib/silcutil/unix/silcunixnet.c and the old
2657 lib/silcutil/silcnet.c includes now only generic routines.
2659 Added WIN32 specific network routines to the
2660 lib/silcutil/win32/silcwin32net.c.
2662 * Added Unix specific utility functions from the
2663 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2665 * Added WIN32 SILC Scheduler to the file
2666 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2669 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Do not handle JOIN notify in the server if the target client
2672 is not registered (idata->registered == FALSE). The affected
2673 file is silcd/packet_receive.c.
2675 * Update the nickrec->founder in event_cumode in the Irssi SILC
2676 client. Affected file irssi/src/silc/core/silc-channels.c.
2678 * Fixed the CUMODE_CHANGE notify handling in the server when
2679 server and router are announcing their clients on channels.
2680 Now the mode changes are saved and notified correctly. The
2681 affected file is /silcd/packet_receive.c.
2683 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2684 They really did not replace the cache entry in the ID Cache.
2685 Now they do that. Affected file silcd/idlist.c.
2687 * Fixed the KICK notify handling in the Irssi SILC client to
2688 update the channel records so that the kicked client does not
2689 appear to be on the channel. The affected file is
2690 irssi/src/silc/core/silc-channels.c.
2692 * Always update the conn->current_channel when executing command
2693 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2695 * Fixed the KILL notify handling in Irssi SILC client to remove
2696 the killed client on all channels.
2698 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Fixed the silc_parse_command_line to remove extra spaces
2701 from the start and end of the arguments. Affected file is
2702 lib/silcutil/silcutil.c.
2704 * Cancel and free any active protocol in the function
2705 silc_server_close_connection. Affected file silcd/server.c.
2707 * Cancel and free any active protocol in the function
2708 silc_client_close_connction. Affected file is
2709 lib/silcclient/client.c.
2711 * Do not execute the KILL command for clients that are in
2712 history (ie. they are not in the network). Affected file is
2715 * Fixed KILL notify handling, client does not crash anymore.
2716 Affected file irssi/src/silc/core/silc-channels.c.
2718 * Reduced the default packet buffer size from 2048 to 1024 in
2719 lib/silccore/silcpacket.c.
2721 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2722 counter to the SKE context that is incresed when the SKE library
2723 performs async operation outside the library. If the outside
2724 process frees the SKE context and FREED status will be set
2725 and the library will detect after the sync operation that the
2726 libary is freed. The affected files are
2727 lib/silcske/silcske[_status].[ch].
2729 * Resolve the client entry information in the function
2730 silc_client_channel_message to assure that NULL pointer is not
2731 passed as client entry to the application. */
2733 * Fixed the task timeout calculation to assure that there is
2734 never negative timeouts. The affected file is
2735 lib/silcutil/silcschedule.c.
2737 * Fixed the channel user mode notification sending in server.
2738 It was sent point-to-point to the router (or to server by router)
2739 but it needs to be destined to a channel. The routines now
2740 supports sending the channel user mode notifys to the channels
2741 when announcing clients and channels. Affected files are
2742 silcd/server.c and silcd/packet_receive.c.
2744 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2745 It did not actually replace the old channel entry in the cache.
2746 Affected file lib/silcclient/client_notify.c.
2748 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Fixed a possible crash in silc_packet_send_prepare. It now
2751 assures always that there is enough space in the buffer and
2752 at the tail area of the buffer (for MAC).
2754 Fixed the inbound buffer reallocation in silc_packet_read.
2755 It was old code and did not handle the reallocation correctly.
2758 The affected file is lib/silccore/silcpacket.c.
2760 * Fixed buffer overflow in silc_parse_nickname in the file
2761 lib/silcutil/silcutil.c.
2763 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * make install generates new server keys only if there is not
2768 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2771 Added check that if the NOREPLY is set then we will not send
2772 the away message. This avoids infinite loop of away messages
2773 if both clients are away. The affected file is
2774 lib/silcclient/client_prvmsg.c.
2776 * Fixed client crash if /NICK was given without arguments.
2777 Affected file lib/silcclient/command.c.
2779 * Server does not send the invite list in INVITE command back
2780 to the client if the list was not altered. Added this notion
2781 to the protocol spec as well. Affected file silcd/command.c.
2783 Fixed possible crash in INVITE command by checking the
2784 value of silc_server_get_client_route command.
2786 * Fixed the INVITE notify type handling. The arguments are now
2787 taken in correct order and client does not crash. The affected
2788 file is irssi/src/silc/core/silc-channels.c.
2790 Removed the "Inviting xxx to channel" message from the
2791 client library away and let the application handle it.
2792 Affected file lib/silcclient/command.c. Added that message
2793 to Irssi SILC client's message formats.
2795 * Fixed CMODE command crash in client. It now checks the
2796 amount of arguments correctly and does not crash. The affected
2797 file is lib/silcclient/command.c.
2799 * Do not create new channel automatically in silc_channels_join
2800 but check whether the channel by that name already exists.
2801 Affected file irssi/silc/core/silc-channels.c.
2803 * Do not send the SERVER_SIGNOFF to router if the disconnected
2804 entity was the router. Affected file silcd/server.c.
2806 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2807 SILC client as it was missing from there.
2809 Added the handling of the KICK notify to the Irssi SILC client
2810 as it was missing. Added "you have been kicked" message to
2811 Irssi SILC client's message modules formats.
2813 Added the handing of the KILL notify to the Irssi SILC client
2814 as it was missing. Added the kill message module formats
2817 The affected file is irssi/src/silc/core/silc-channels.c.
2819 * The router did not save the channel mode the server announced.
2820 Affected file silcd/packet_receive.c.
2822 * Fixed a possible crash in INFO command in server. If the
2823 server did not provide the server info it crashed. Affected
2824 file silcd/command.c.
2826 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Fixed the GETKEY command in the server to check also the
2829 global list. Otherwise the GETKEY would not work correctly
2830 in normal SILC server. Affected file silcd/command.c.
2832 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Fixed GETKEY crash, it crashed if the command did not succseed.
2836 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2838 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2839 is now real and not just an macro interface to GMP.
2841 Removed the entire GMP from the source tree and imported new
2842 NSS MPI library instead. Reason for removing GMP is that it is
2843 extremely large and compiles extremely slow. The NSS MPI
2844 is only a few files and compiles in less than 10 seconds.
2845 The speed is also about the same as GMP. The MPI is imported
2846 to lib/silcmath/mpi.
2848 If the system has GMP installed we will still use the GMP.
2849 If it is not then the NSS MPI will be compiled.
2851 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2853 * Merged a long nickname (127 characters long) crash bugfix from
2854 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2856 * Merged a freed memory reference bugfix from Irssi CVS tree.
2857 Affected file irssi/src/core/commands.c.
2859 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Added the server's public key sving and verification to the
2862 server when performing the SKE. This was missing and the
2863 remote server's (or router's) public key was accepted without
2864 checking whether we have it previously or trust it at all.
2865 Affected file silcd/protocol.c.
2867 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2869 * Check in the silc_server_timeout_remote if protocol is active
2870 and make sure that the protocol's final callback is called so
2871 that all memory if freed. Affected file silcd/server.c.
2873 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * silc_server_whois_send_reply crashed the server if the nickname
2876 was 127 characters long. Affected file silcd/command.c.
2878 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Added sanity check to the silc_server_new_client. If the hostname
2881 is provided inside username then check that the provided hostname
2882 really is the same as the resolved one. If the hostname was not
2883 resolved then check it from the public key. Affected file is
2884 silcd/packet_receive.c.
2886 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2887 if the server disconnected us and the connection is not valid
2888 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2890 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2891 the library to the lib/silcutil/silcutil.[ch].
2893 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Close log file after open. Affected file
2896 lib/silcutil/silclog.c.
2898 * Check whether sock == NULL in silc_client_send_packet and return
2899 if it is. Affected file lib/silcclient/silcclient.c.
2901 * Check rec->entry == NULL in the Irssi SILC Client before
2902 sending the channel message. Affecte file is
2903 irssi/src/silc/core/silc-servers.c.
2905 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Merged a splitted window bugfix from Irssi CVS tree. The
2908 affected file is irssi/src/fe-text/textbuffer-view.c.
2910 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2911 It did not print nickname.
2913 * Improved the distributions system a bit.
2915 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2918 irssi/src/fe-text/gui-window.c.
2920 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2921 to in-active server. The affected file is
2922 irssi/src/silc/core/client_ops.c.
2924 * Resolve the client in USERS command reply if the entry does
2925 not have username resolved. The affected file is
2926 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2927 command to WHOIS command to really resolve stuff. The USERS
2928 is not used any more in any critical section so WHOIS can
2929 be used even though it might be slower than IDENTIFY.
2931 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2934 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Changed the protocol API a bit more consistent in the
2937 lib/silccore/silcprotocol.[ch].
2939 * Changed the following headers to ROBODoc format:
2941 lib/silccore/silcpayload.h
2942 lib/silccore/silcprotocol.h
2943 lib/silccore/silcsockconn.h
2945 All core library headers are now formatted.
2947 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Fixed a bug in Irssi SILC client; do not show that you are
2950 server/router operator if you really are not. Affected file is
2951 irssi/src/silc/core/client_ops.c.
2953 * Renamed silc_command_free_payload to silc_command_payload_free.
2954 Affected file lib/silccore/silccommand.h
2956 * Added silcmath.h to include the prototoypes of various routines
2957 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2960 * Changed the following headers to ROBODoc format:
2962 lib/silccore/silcchannel.h
2963 lib/silccore/silccommand.h
2964 lib/silccore/silcid.h
2965 lib/silccore/silcidcache.h
2966 lib/silccore/silcmode.h
2967 lib/silccore/silcnotify.h
2968 lib/silccore/silcpacket.h
2969 lib/silcmath/silcmath.h
2971 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added checking to the server code not to start the server if
2974 ciphers and stuff are not configured properly. Affected files
2975 silcd/serverconfig.[h] and silcd/server.c.
2977 * Changed the layout of the header files of the public interfaces
2978 in the SILC libraries. The new layout supports ROBODoc
2979 documentation tool (and some others) so that it is easy to create
2980 a library reference manual. All the other headers and source
2981 code must still follow the CodingStyle document. Also source
2982 code must not include these ROBODoc stuffs, only the headers.
2983 Furthermore, all public interface headers must now be named
2984 by using `silc' prefix, example: silcapi.h, silccipher.h.
2985 Some files were renamed due to this. All the other headers
2986 must not be used as public interfaces. I will update the
2987 CodingStyle document later. Changed following headers, so far:
2989 lib/silcclient/silcapi.h
2990 lib/silccore/silcauth.h
2991 lib/silccore/silcprivate.h
2992 lib/silccrypt/silcdh.h
2994 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Removed silc_client_packet_send_flush from the client library
2999 as it is not needed. Affected file lib/silcclient/client.[ch].
3001 * Added printing of message of unresolved authentication method
3002 to the Irssi SILC client. Added it to the module formats.
3003 Removed the same message from the client library.
3005 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Added new distribution feature, DISTLABEL. Every distribution
3008 can define own preprocessor label that can be used in the
3009 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3010 file distributions, acconfig.h.pre and prepare.
3012 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added Makefile.defines_int to include the actual definitions
3015 for Makefile.defines.in. Tested the new distribution system,
3016 created distributions and tested installation.
3018 * Added AWAY message printing to the Irssi SILC client. Added
3019 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3021 * Added SCONNECT command to call the SILC's CONNECT command.
3022 Cannot use CONNECT directly since Irssi uses that internally.
3023 Affected file irssi/src/silc/core/silc-servers.c.
3025 Added ACTION local command. It is same as ME command but takes
3026 the channel as mandatory argument.
3028 Rewrote some of the Irssi's help files to suite for SILC
3031 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Added Makefile.defines[.in] that should for now on be included
3034 in all Makefile.am file in the source tree. That file includes
3035 all common compilation definitions for SILC source tree.
3037 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Minor changes to the ./prepare script to change the package
3040 name according the distribution name to the configure.in.
3042 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Created new distribution system. Added file `distributions'
3045 that defines all the distributions that can be created out of
3046 the SILC source tree. The ./prepare script now reads that
3047 file to determine how to prepare the distributions. The
3048 first argument to the ./prepare is the name of the distribution
3049 and second is the version of the distribution. If given
3050 without arguments it creates the default (toolkit) distribution
3051 with the default version (defined in ./prepare).
3053 All Makefile.am files that are subject to the distributions
3054 are now named as Makefile.am.pre. These are ./Makefile.am
3055 and lib/Makefile.am. Others may be changed later.
3057 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Added invite list, ban list, some key management and connection
3060 error message printing to module formats in the Irssi SILC client.
3062 * Added new silc_client_set_away_message to set the away message
3063 that is back to the person who sent private message. The
3064 affected file lib/silcclient/silcapi.h and the
3065 lib/silcclient/client_prvmsg.c.
3067 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Fixed the private message sending in the Irssi SILC client,
3070 added local command KEY to the Irssi SILC client.
3072 Added key management and key agreement message formats to the
3073 irssi/src/fe-common/silc/module-formats.[ch].
3075 Added USERS (alias WHO) printing, server/router operator
3076 indication and LIST command printing to the module formats.
3078 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3080 * Fixed channel joining notify handling, cumode notify handling
3081 from Irssi SILC client.
3083 * Added SILC specific module-formats to the Irssi SILC client so
3084 that SILC specific message hilighting, colors etc is possible.
3085 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3087 Added channel mode, channel user mode, actions, notices,
3088 whois and whowas printing to the the module-formats.c.
3090 * Fixed a bug in channel deletion in the server. The channel
3091 is not left to the cache even if the channel founder auth mode
3092 is set when there are no users anymore on the channel. Affected
3093 file silcd/server.c.
3095 * The silc_net_localhost now resolves the entire hostname including
3096 the domain name. Affected file lib/silcutil/silcnet.c.
3098 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3100 * Changed the ask_passphrase client operation to be ascynchronous.
3101 It has now a completion callback and a context that the
3102 application must call after it has got the passphrase from
3103 the user. Affected files lib/silcclient/silcapi.h,
3104 lib/silcclient/protocol.c, lib/silcclient/command.c and
3107 Added SilcAskPassphrase callback that the application calls
3108 to deliver the passphrase to the library.
3110 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3111 The public key verification and especially a certificate
3112 verification is asynchronous procedure.
3114 Added new SILC_SKE_STATUS_PENDING status to indicate the
3115 request is pending and a callback will be called to finalize
3118 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3119 indicate that remote end did not send its public key (or
3120 certificate), even though we require it. Added check for this
3121 condition in the SKE. This was a security bug, now fixed.
3123 Defined new SilcSKEVerifyCbCompletion callback that is called
3124 when the verification process is completed.
3126 The affected files lib/silcske/silcske_status.h and
3127 lib/silcske/silcske.[ch].
3129 * Changed the verify_public_key client operation to be async
3130 as well. Defined SilcVerifyPublicKey callback that is used to
3131 indicate the success of the public key verification process.
3133 Changed the server and client to use the new async client
3136 * Changed the Irssi SILC client's internal scheduler to be called
3137 twice as many times as it used to be. As a result the client
3138 should be a bit faster now. Affected file is
3139 irssi/src/silc/core/silc-core.c.
3141 * Added support to Irssi SILC client of asynchronous public key
3142 verification and passphrase inquiry. Affected file is
3143 irssi/src/silc/core/silc-core.c.
3145 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Do not say "You have left channel %s" in client library.
3148 Moved it to the application. Affected files are
3149 lib/silcclient/command.c and silc/client_ops.c.
3151 * Fixed silc_client_get_clients. Command context was not
3152 duplicated and was freed memory in the callback. Affected
3153 file lib/silcclient/idlist.c.
3155 * Do not say "you are now talking..." on JOIN command in the
3156 client library. The appliation must handle it.
3158 * Do not say ".. changed topic to" in command reply in the
3159 client libary. The application must handle it.
3161 * Fixed TOPIC command sending in the client library.
3163 * Fixed a memory leak in silc_client_command_free in the file
3164 lib/silcclient/command.c.
3166 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Imported a modified version of Irssi client to the source tree.
3169 The Irssi will be used to create a new client called
3170 Irssi SILC. Imported to irssi/.
3172 Added silc_core_init_finish function to the Irssi. Affected
3173 file irssi/configure.in.
3175 A lot changes in the Makefile.ams around the irssi tree.
3177 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Do not rehash if the new size is same as the old size of the
3180 hash table, in the silc_hash_table_rehash*. The affected file
3181 lib/silcutil/silchashtable.c.
3183 * Replaced hash_table_del_by_context calls from the server
3184 (when channel->user_list and client->channels) to the
3185 hash_table_del as it is sufficient and faster.
3187 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Added silc_hash_table_list, silc_hash_table_get and the
3190 SilcHashTableList structure to provide an alternative way to
3191 traverse the hash table. The affected files are
3192 lib/silcutil/silchashtable.[ch].
3194 * Changed the server's idlist routines to use the hash table
3195 routines to optimize the code.
3197 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Replaced the client entry's `channel' list and channel entry's
3200 `user_list' list to hash tables for optimized lookup. Changed
3201 the code to use the hash table interface around the code.
3202 Affected file lib/silcd/idlist.[ch].
3204 * Added `auto_rehash' boolean argument to the function
3205 silc_hash_table_alloc to indicate whether the hash table should
3206 auto-rehash when it thinks is appropriate time. It will
3207 increase the hash table size if the there is twice as much
3208 entries in the table than the size of the table, and will
3209 decrease the size if there are twice as less entries than
3210 the size of the table.
3212 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3216 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * silc_idcache_purge_by_context deletes the entry now by context
3219 as it is supposed to do. Affected file lib/silccore/idcache.c.
3221 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3222 client is not anymore valid (WHOWAS givens the info) and not
3223 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3225 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Removed the `data' and `data_len' arguments from the ID Cache
3228 interfaces and added `name' argument. ID Cache does not handle
3229 anymore the binary data only a names associated with given ID.
3231 * When hashing a Client ID with silc_hash_id the entire ID is
3232 not hashed anymore, instead only the hash of the Client ID is
3233 hashed. This way we can access the Client ID from the cache
3234 with Client ID but with the hash of the ID (which is a hash of
3235 the nickname) as well without any difference in performance.
3237 Added also silc_idcache_find_by_id_one_ext to do one on one
3238 searching when we have the actual ID. Added also function
3239 silc_hash_client_id_compare. The affected files are
3240 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3242 * When hashing the name associated with a ID it is always done
3243 in lowercase. This way we can access the cache without worrying
3244 about case-sensitivity, even though, for example nicknames are
3247 * Fixed a bug in server with channel message sending. It put
3248 wrong ID type as destination ID. The affected file
3249 silcd/packet_send.c.
3251 * silc_idcache_del_by_context now deletes from all hash tables
3252 by context. Affected file lib/silccore/idcache.c.
3254 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Changed the client library to use the new ID Cache interface.
3257 Changes around the source tree.
3259 * Added silc_hash_table_rehash_ext to rehash with specific
3260 hash function. Affected file lib/silcutil/silchashtable.[ch].
3262 * Added silc_hash_string_compare to compare two strings in the
3263 hash table. Affected file lib/silcutil/silcutil.[ch].
3265 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Added new function silc_idcache_del_by_context into the
3268 lib/silccore/idcache.[ch].
3270 * Changed the server's ID list routines to use the new ID Cache
3271 interface. Changes around the source tree.
3273 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Added silc_hash_table_del[_by_context]_ext functions in to the
3276 lib/silcutil/silchashtable.[ch].
3278 Removed silc_hash_table_find_all* routines and added new
3279 silc_hash_table_find_foreach to replace them.
3281 Added silc_hash_table_replace_ext function as extended
3282 replacing function. Separated the simple hash table interface
3283 from the extended hash table interface in the file
3284 lib/silcutil/silchashtable.h.
3286 * Fixed minor bugs and changed it to use some of the new
3287 hash table functions in lib/silccore/idcache.c
3289 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Added new function silc_hash_table_find_all to return all keys
3292 in the hash table by the specified key. As the hash table is
3293 collision resistant it also makes it possible to have several
3294 duplicate keys in the hash table. This function may be used to
3295 find all of the keys from the hash.
3297 Added user_context arguments to the SilcHashFunction,
3298 SilcHashCompare and SilcHashDestructor to deliver user specified
3301 Added new fuctions silc_hash_table_find[_all]_ext to do
3302 extended lookup with specified hash and compare functions and
3303 specified user contexts.
3305 Added new function silc_hash_table_add_ext to add the key
3306 with specified hash function and user context.
3308 Added new function silc_hash_table_foreach to traverse all
3309 entrys in the hash table. Added SilcHashForeach callback
3312 Added new function silc_hash_table_del_by_context to delete
3313 the entry only if the context associated with the key matches.
3315 Affected files are lib/silcutil/silchashtable.[ch].
3317 * Removed silc_hash_[server/client/channel]_id and added just
3318 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3319 silc_hash_id_compare to compare two ID's using as the hash table
3320 comparison function. Added also silc_hash_data to hash
3321 binary data and silc_hash_data_compare to compare it.
3323 * Removed silc_idlist_find_client_by_hash as it is not needed
3324 anymore. Affected file silcd/idlist.[ch].
3326 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3327 to use internally the SilcHashTable. The new ID Cache is a lot
3328 faster than the old one. Some of the ID Cache interface was also
3329 rewritten and obsolete and stupid functions were removed.
3331 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Added entry_count field to the SilcHashTable to keep the number
3334 of the entries in the table. Implemented the function
3335 silc_hash_table_rehash. Added new function
3336 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3338 Fixed a minor bug in silc_hash_table_free.
3340 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3341 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3342 into the lib/silcutil/silcutil.[ch].
3344 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3346 * Implemented a collision resistant hash table into the
3347 lib/silcutil/silchashtable[ch]. See the header and the source
3348 for the SilcHashTable API.
3350 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Merged dotconf version 1.0.2 into lib/dotconf.
3354 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Do not compile anything in lib/silcsim/* if the SIM support
3357 is not enabled. The tree should now compile without problems
3360 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Compiled the SILC under cygwin. Compiled and tested briefly
3363 without problems. More tests needed. The SIMs didn't compile
3366 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3368 * Fixed possible crash in silc_get_username in the
3369 lib/silcutil/silcutil.c.
3371 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Fixed a va_arg in silc/client_ops.c.
3375 * Oops, RC5 routines were named AES and caused some problems
3376 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3378 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Added new SilcIDIP structure into the lib/silccore/id.h and
3381 replaced the old `ip' fields from all SILC ID's to that type.
3382 This is a step towards IPv6 support.
3384 The silc_id_get_len takes now the ID as an extra argument.
3385 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3386 both IPv4 and IPv6 based ID's.
3388 The affected files are lib/silccore/id.[ch] and other files
3389 around the tree using these routines.
3391 * Removed the ID length arguments in server from various
3392 silc_server_send_notify_* routines -> they are not needed
3395 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Fixed memory leak in silc_encode_pem_file in the file
3398 lib/silcutil/silcutil.c.
3400 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Check minor version as well in the SKE. Affected files are
3403 silcd/protocol.c and lib/silcclient/protocol.c.
3405 * Added --identifier option to the server so that an identifier
3406 can be when creating the public key for the server. Affected
3407 file is silcd/silcd.c.
3409 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3410 lib/silccrypt/silcpkcs.c.
3412 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Register default ciphers and stuff when using -C option with
3415 the server. Affected file sildc/silcd.c.
3417 * Put back the servers public key filename format, it is better
3418 than the new one. For now, the client keys are saved with the
3419 new filename format. The affected file silc/client_ops.c.
3421 * Implemented the Cipher API for the rest of the ciphers that
3422 did not implement it or implemented it the wrong way.
3424 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Register default ciphers and stuff when using the -S option
3427 in the client. Affected file silc/silc.c. Same also when
3428 creating new key pair with -C option.
3430 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Fixed the silc_verify_public_key client operation function to
3433 save the public keys differently. The fingerprint is now
3434 used as filename and not the hostname. This way also the
3435 client keys are saved uniquely and not with hostnames. The
3436 affected file is silc/client_ops.c.
3438 * Trimmed the silc_hash_fingerprint function to remove extra
3439 whitespaces from the end of the fingerprint. The affected
3440 file is lib/silccrypt/silchash.c.
3444 * Added silc_cipher_register_default function to register all
3445 default ciphers. It can be used when configuration files
3446 does not exist and the application does not want any specific
3447 ciphers in any specific order.
3449 The SilcDList is now used as silc_cipher_list dynamically
3450 allocated cipher list. Removed the static list all together
3451 and now all ciphers must be allocated to the dynamic list.
3452 The silc_cipher_alloc routine was changed to check only the
3455 All silc_cipher_* routines that used to return int returns
3458 The affected files lib/silccrypt/silccrypt.[ch].
3460 * The same thing was done to silc_hash_* as for silc_cipher_*
3461 routines. Affected files lib/silccrypt/silchash.[ch].
3463 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3464 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3465 Added also silc_pkcs_[un]register[_default] functions.
3466 Removed the data_context from the PKCS API.
3468 * Added silc_hmac_register_default function to register default
3469 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3470 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3471 to unregister all hmacs at once.
3473 * Register the default ciphers, hash functions, PKCSs and HMACs
3474 if client's configuration file does not exist. The affected
3477 * The client did not load the hash functions from the SIM
3478 modules at all. Added support for this. Affected file is
3479 silc/clientconfig.c.
3481 * When decoding public key with silc_pkcs_public_key_decode, check
3482 the supported algorithm only if PKCS are registered. Affected
3483 file lib/silccrypt/silcpkcs.c. The same was done with the
3484 silc_pkcs_private_key_decode.
3486 * Fixed the SILC List routines to keep the list always in order.
3487 It used to change the list's order when traversing the list but
3488 not it preserves the order. Affected file lib/trq/silclist.h.
3490 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Added the client library to use the SilcSocketConnection's
3493 reference counter (by silc_socket_dup) to prevent the bug that
3494 the socket object may be freed underneath async operation.
3496 * The name resolv library checking fixes in the configure.in.pre.
3499 * Created new version of the protocol drafts for future
3500 development. The -03 drafts are the ones that will be changed
3501 in the trunk now and the -02 will remain as they are.
3503 * Send list of CUMODE notifys to the router when announcing
3504 the channel users to the router. Affected file silcd/server.c.
3505 If the router receiving channel founder CUMODE for a channel
3506 that already has channel founder it will send CUMODE notify
3507 to the sender to remove the channel founder rights from the
3508 announced client. Affected file silcd/packet_receive.c.
3510 * The CUMODE notify may now use Server ID as well as the entity
3511 who changes the mode. Updated protocool specs.
3513 * Updated INSTALL and README files.
3515 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3517 * New web pages in the http://silc.pspt.fi. The pages was
3522 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Implemented the [DenyConnectin] config section in the server.
3525 Added silc_server_config_denied_conn to check whether incoming
3526 connection is denied. Affected file silcd/serverconfig.[ch].
3528 * Do not check the ports when checking the incoming configuration
3529 data if the port is 0, meaning any. Affected file is
3530 silcd/serverconfig.c.
3532 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Fixed buffer overflow in silc_string_compare in the file
3535 lib/silcutil/silcutil.c.
3537 * Fixed double free in silc_server_command_leave in the file
3540 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Fixed the version checking in the server. Affected file is
3545 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Fixed the configuration data fetching when accepting new
3548 connections in the server. Affected file silcd/server.c.
3550 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Added `sender_entry' argument to the function
3553 silc_server_packet_relay_to_channel so that we can check
3554 whether some destination actually belongs to the same route
3555 the sender belongs (ie, we must not resend the packet to the
3556 sender). Affected file silcd/packet_send.[ch].
3558 * Added `servername' field to the SilcClientEntry in the server
3559 to hold the name of the server where client is from. Affected
3560 file is silcd/idlist.h.
3562 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Moved the channel message encrypting in the router betwen
3565 router connections from silc_server_channel_message to the
3566 silc_server_packet_relay_to_channel since we want to check
3567 whether we have anybody channel before encrypting anything.
3568 Affected files silcd/packet_[receive/send].c.
3570 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3572 * Fixed the [AdminConnection] server config section to support
3573 multiple entries. Affected file silcd/serverconfig.c.
3575 * Added support into the server to check the validity of the
3576 incoming connection before executing any KE or authentication
3579 * The connection configuration is now saved to the KE and
3580 connection auth protocol contexts and not fetched anymore in
3581 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3583 * The local hosts listenning address and port is also resolved
3584 now when starting the server. We want to have the socket object
3585 to include the real address and port for the listener. Added
3586 new function silc_net_check_local_by_sock into the files
3587 lib/silcutil/silcnet.[ch].
3589 * Fixed a broadcast bug in server -> do not broadcast if we
3592 * Fixed a routing bug. Do not route broadcast packets ever.
3593 Broadcast packets must be processed always and not routed since
3594 they may be destined to some other host than yourself and thus
3595 would get routed without no good reason. Affected file is
3598 * Added function silc_server_config_is_primary_route to check
3599 whether primary router connection has been configured (a router
3600 configuration that we are initiating). If there is not, we
3601 will assume that there is only two routers in the SILC network
3602 and we will use the incoming router connection as our primary
3603 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3605 * Changed the order of the broadcasting. Broadcast _after_ the
3606 packet has been processed not before. Affected file is
3609 * Fixed a [ClientConnection] parsing bug. The port was never
3610 parsed correctly thus resulting to port 0. Affected file
3611 silcd/serverconfig.c.
3613 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3614 argument and did not set the broadcast packet flag. Affected
3615 file silcd/packet_send.c. Fixed same bug in the function
3616 silc_server_send_notify as well.
3618 * If we receive NEW_ID packet for our own ID in the server, ignore
3621 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Removed the nickname from the Private Message Payload.
3626 Updated the code and the protocol specs.
3628 * Updated protocol specs for submitting to the IETF.
3630 * Tweaked the Random Number Generator a bit. Affected file
3631 lib/silccrypt/silcrng.c. Exported a new function
3632 silc_rng_[global]_add_noise which can be used to add more
3635 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * Do not parse packets with different timeout when protocol
3638 is active -> may cause problem with rekey. Affected file
3641 * When server receives signoff notify it must not create
3642 new channel key if the client is on any channels since the
3643 sender of the signoff notify will create it.
3645 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Added printing of error messages during SKE protocol from the
3648 failure packet sent by server during SKE. Affected file
3651 * Removed the client's failure_callback handling with timeout
3652 and handle it immediately when received.
3654 * The SKE library returned wrong type in SUCCESS and FAILURE
3655 packets. They must be 32 bit MSB not 16 bit MSB.
3657 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3659 * Ok, rewrote the logic of the re-key and now it seems to work.
3660 I tested it on high traffic with frequent re-keys without
3661 problems. Added hmac_receive (and renamed hmac to hmac_send)
3662 in SilcClientConnection in lib/silcclient/client.h and
3663 in SilcIDListData in silcd/idlist.h. Also, removed the
3664 SilcPacketParserContext's cipher and hmac fields as they are
3665 not needed anymore and actually caused some problems when
3666 the ciphers and hmac's changed underneath the packet parser.
3668 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * If re-key protocol is active then process the incoming packets
3671 synchronously since we must assure that icoming packets encrypted
3672 with the old key is processed before the new keys is set to
3673 use. This is true other packets than for REKEY packets.
3674 Affected file silcd/server.c. The same was done to client library
3675 as well, affected file lib/silcclient/client.c.
3677 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Fixed bug in client and server to accept the force send if
3680 the packet is send from silc_[server/client]_packet_process
3681 function. Otherwise the packets are never delivered, oops.
3683 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Disable force sending of packets when REKEY protocol is active.
3686 We must assure that no packet is sent directly when rekey is
3687 performed. All packets must be sent through packet queue.
3688 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3689 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3690 function is silc_[server/client]_packet_send_real to check
3693 * Replaced the SIM paths from example config files to
3694 /usr/local/modules. Also, make install creates now
3695 /usr/local/silc/logs directory to hold all the SILC server
3698 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Made the configure.in.pre work on Solaris. Patch by salo.
3702 * Made all ciphers compatible with non-x86 machines. Defined
3703 CBC mode macros into lib/silccrypt/ciphers_def.h.
3705 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Fixed the make install.
3709 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * When MAC computation fails the silc_packet_decrypt returned 0
3712 even though it was supposed to return -1. Fixed this. The
3713 affected file is lib/silccore/silcpacket.c.
3715 * Do not replace the config files in /etc/silc (in make install)
3716 if they already exist. Affected file ./Makefile.am.
3718 * Do not send re-key packets immediately but through packet queue.
3719 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3721 * Changed silc_net_check_host_by_sock to return FALSE if the
3722 IP/DNS could not be resolved. Though, it returns the IP address
3723 now even if it could not resolve it (but returns also FALSE).
3724 Affected file lib/silcutil/silcnet.[ch].
3726 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3734 contents of the specified public key file.
3736 * Changed the PKCS api to return the public key length when
3737 setting the public key.
3739 * Fixed a fatal bug in the public and private key file loading.
3740 Affected file lib/silccrypt/silcpkcs.c.
3742 * Execute the packet parsing for client with zero (0) timeout
3743 if the protocol is active. Affected file silcd/server.c.
3745 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Made the key generation options to the silcd program. Added
3748 -C option, equivalent to client's option.
3750 * Added new [ServerKeys] config section to the server. It
3751 configures the server's public and private key.
3753 * Defined generic Public Key Payload into the protocol
3754 specification to send specific type of public keys and
3757 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3758 public key or certificate.
3760 * Implemented the GETKEY command to the server and to the
3761 client library and on user interface.
3763 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3767 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Added SilcServerRekey context into silcd/idlist.h.
3771 * Added the PFS support as defined in the specification to the
3772 SKE protocol. Affected files lib/silcske/*.c.
3774 * Added `ske_group' field to the SilcServerRekey context to hold
3775 the number of the SKE group that is used with PFS in re-key.
3776 Affected file silcd/idlist.h.
3778 * Added PFS re-key support to the server. Affected file is
3781 * Added silc_protocol_cancel to cancel execution of the next
3782 state of the protocol. Affected file is
3783 lib/silccore/silcprotocol.[ch].
3785 * Added the re-key support with and without PFS to the client
3786 library. Re-key is performed once in an hour, by default.
3788 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3789 Added silc_client_rekey_callback and silc_client_rekey_final.
3790 Affected files are lib/silcclient/protocol.[ch] and
3791 lib/silcclient/client.[ch].
3793 * Removed the `hmac_key' and `hmac_key_len' fields from the
3794 SilcClientConnection structure; not needed. Affected file is
3795 lib/silcclient/client.h.
3799 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3801 * Do not ask whether user wants to use the negotiated private key
3802 for private messages, just use it. Affected file is
3803 silc/local_command.c.
3805 * Added `send_enc_key' and `enc_key_len' fields to the
3806 SilcIDListData structure since they are needed in the re-key
3807 phase. Affected file is silcd/idlist.[ch].
3809 * Implemented the simple re-key protocol into the server.
3810 Affected files silcd/server.c and silcd/protocol.[ch]. The
3811 re-key will be performed once in an hour, by default.
3813 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3814 Added silc_server_rekey, silc_server_rekey_callback and
3815 silc_server_rekey_final.
3817 * Removed Tunneled flag from the protocol. Updated the code
3818 and the specifications.
3820 * Adde `pfs' field to the SilcIDListData to indicate whether
3821 the PFS is to be performed in the re-key. Affected file is
3824 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3827 int64 of at least the xintXX size. If void * is less that 4
3828 bytes uint32 * will be used. Defined bool as boolean.
3830 * Changed _ALL_ unsigned long and unsigned int to uint32,
3831 unsgined short to uint16 in the source tree.
3833 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3834 not handle clients that has entry->data.registered == FALSE.
3835 They are not in the network anymore. Affected file is
3838 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Implemented the sending of the SERVER_SIGNOFF notify in the
3841 server. Affected file is silcd/server.c.
3843 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3844 Added also silc_notify_payload_encode_args into the
3845 lib/silccore/silcnotify.[ch].
3847 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3848 Affected file silcd/packet_receive.c.
3850 * Implemented the SERVER_SIGNOFF notify handling in the client
3851 library. Affected file lib/silcclient/client_notify.c. Also,
3852 implemnted the printing of the SERVER_SIGNOFF info to the
3853 application. Affected file silc/client_ops.c.
3855 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3856 if the deleting was successful. Affected file silcd/idlist.[ch].
3858 * Added support for public key authentication in the connection
3859 authentication protocol in the client library. Affected file
3860 lib/silcclient/protocol.c.
3862 * Changed the server's silc_idlist_get_clients_by_* interface
3863 to support already allocated array so that new entries may be
3864 added to pre-allocated array. Affected file silcd/idlist.[ch].
3865 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3866 and command replies.
3868 * All command reply functions in the server now calls the
3869 pending command callback even if error occured. This way the
3870 error will be delivered to the client as well. Affected files
3871 silcd/command.c and silcd/command_reply.c.
3873 * Fixed INFO command to return local server's info if no server
3874 was provided. Affected file lib/silcclient/command.c.
3876 * Removed RESTART command for good. Updated the code and the
3879 * Rewrote parts of the task system. It is a bit simpler now.
3880 Removed unsued task priorities. The affected files are
3881 lib/silcutil/silctask.[ch].
3883 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Moved the USERS printing from the library to the application.
3886 Affected files lib/silcclient/command.c and silc/client_ops.c.
3888 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Added channel key re-key support. The re-key is perfomed
3893 only by the router and is done once in an hour. Added `rekey'
3894 field to the SilcChannelEntry in the server. Affected files
3895 silcd/server.c and silcd/idlist.h.
3897 * Added silc_task_unregister_by_context into the file
3898 lib/silcutil/silctask.[ch].
3900 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Added SILC_UMODE_GONE mode to indicate when the client is not
3903 present in the SILC network. Added also support to the local
3904 command AWAY that will set this mode. Added support of showing
3905 "xxx is gone" in WHOIS command. The USERS command shows the
3906 gone status as well.
3908 * Fixed setting server and router operator privileges in the
3909 server's UMODE command. Affected file silcd/command.c.
3911 * Merged the SKE KE1 and KE2 payloads into one payload. The
3912 new KE payload is equivalent to the old KE2 payload.
3914 Cleaned up the SKE Start Payload parsing. It now uses the
3915 simple buffer unformatting to do the parsing. A lot faster
3918 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3919 to the SKE that is used to indicate whether both of the SKE
3920 parties should perform authentication. By default only the
3921 responder performs authentication. By setting this flag also
3922 the initiator must do authentication. By default it is unset
3923 since in normal SKE case, client to server connection, only
3924 the responder should do authentication. When doing SKE between
3925 two clients both should perform authentication. Updated the
3926 code and the protocol specs.
3928 * A little fix to IDENTIFY command in the server. Search the
3929 client first by hash not nickname. Affected file is
3932 * Fixed the silc_client_close_connection to support closing
3933 the client to client connections wihtout deleting too much
3934 data. Affected file lib/silcclient/client.c.
3936 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3937 are received if protocol used to be active but is not anymore
3938 the application would crash due to NULL pointer dereference.
3939 Affected files silcd/server.c and lib/silcclient/client.c.
3941 * Added `hash' field to the SilcClientConnection to include
3942 the hash function negotiated in the SKE protocol.
3944 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3945 to set the channel founder authentication data. A client can
3946 claim the founder rights later by providing the authentication
3947 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3948 This way the channel founder can regain the channel founder
3949 privileges even it is left the channel. This works only on
3950 local server and the client must be connected to the same
3951 server to be able to regain the founder rights. Updated the
3952 protocol specs accordingly.
3954 Added support to the CMODE command in the client to set the
3955 founder auth data. Read the README to see how to set it.
3957 Added support to the CUMODE command to claim the founder
3958 rights. Read the README to see how to do it.
3960 Added support for the founder authentication to the Channel
3961 Entry in the server. Affected file silcd/idlist.h.
3963 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3964 server's CMODE command. Affected file silcd/command.c.
3966 * Added the following new functions into lib/silccore/silcauth.[ch]:
3967 silc_auth_get_method and silc_auth_get_data.
3969 * The server now saves the remote hosts public key to the
3970 SilcIDListData pointer. Affected file silcd/protocol.c.
3972 * The normal server now does not remove the channel entry from
3973 the cache if the founder authentication data is set. It used
3974 to remove it if the founder was the last one on the channel on
3975 the server and left the channel. The auth data is saved and
3976 if the channel is re-joined later the old entry is used with
3977 the old auth data. Affected files silcd/command_reply.c and
3980 * Removed the `pkcs' field from the SilcIDListData structure
3981 in the server; it is not used. Affected file silcd/idlist.h.
3983 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Fixed packet processing on slow links. Partial packets were
3986 never re-processed because the incoming data buffer was cleared
3987 by the application. Application must not directly clear the
3988 sock->inbuf, the packet processing routines handle it. Fixed
3989 this in client library and in server.
3991 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Fixed the WHOIS and IDENTIFY send reply function to really
3994 check whether to send list or just one entry. Affected file
3997 * Cleaned up the LEAVE command's channel key distribution. The
3998 affected file silcd/command.c.
4000 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4001 can enforce the channel mode as well. In that case the ID
4002 includes the ID of the server. The code now enforces the
4003 mode change if the router have different mode than the server.
4005 * The notify client operation with CMODE_CHANGE notify can now
4006 return NULL client_entry pointer if the CMODE was not changed
4007 by client. Application must check for this.
4009 * Added <Server ID> argument to INFO command to support server
4010 info fetching by Server ID.
4012 * Added silc_server_announce_get_channel_users to get assembled
4013 packets of channel users of the specified channel. Affected
4014 file silcd/server.[ch].
4016 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4017 was freed underneath the ID Cache.
4019 * Re-announce clients when the server received CHANNEL_CHANGE
4020 notify from the router. Affected file silcd/packet_send.c.
4022 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4025 crashed since it did not handle the fact that there is no cipher
4026 called "3" and didn't check the error condition. Now fixed.
4028 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4029 flag. It can be used to send message requests.
4031 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Implemented the RESTART command in the client.
4035 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4036 notice type messages. Added notice printing to the user
4039 * The channel keys are not re-generated if the channel's mode
4040 is PRIVKEY, ie private key on the channel exists. Affected
4041 files silcd/server.c and silcd/command.c.
4043 * Fixed a little bug in channel message delivery when channel
4044 private keys are set in the server. Affected file is
4045 silcd/packet_send.c.
4047 * Changed the setting on channel->on_channel = TRUE from the
4048 silc_client_save_channel_key to the JOIN command reply. The
4049 key payload is not received if the private channel key is set.
4050 Affected file lib/silcclient/command_reply.c and the
4051 lib/silcclient/client_channel.c.
4053 * When the CMODE_CHANGE notify is sent and the channel private
4054 key mode is removed the channel key must be re-generated in
4055 other cells as well. Added this support for the router in the
4056 silcd/packet_receive.c.
4058 * Added new local command NOTICE to send notice message on
4059 channel. Affected file silc/local_command.[ch].
4061 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Added new local command ME to the client. It is used to send
4064 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4065 some action. Affected file silc/local_command.[ch].
4067 * Changed channel_message and private_message client operations
4068 to deliver the message flags to the application. Added also
4069 the `flags' arguments to the silc_client_send_channel_message
4070 and silc_client_send_private_message functions. Affected file
4073 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Redefined the Private Message Payload to support private message
4076 keys and to support the new private message flags. Updated
4077 the protocol specs. Flags makes it possible to have for example
4078 CTCP style messages.
4080 * Added new type SilcPrivateMessagePayload and defined an API
4081 for it in the lib/silcclient/silcprivate.[ch].
4083 * Tested private message private keys successfully. Tested the
4084 private message key set, unset and list commands with the new
4087 * Redefined the Channel Message Payload to include the channel
4088 message flags (equal with private message flags) to support
4089 for example CTCP style messages.
4091 * Defined some of the message (for channel and private message)
4092 flags. Updated the protocol specs and added the flags to the
4093 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4095 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Added SilcKeyAgreementStatus type to the key agreement routines
4098 to indicate the current status and error if one occured.
4099 The status types are defined in the lib/silcclient/silcapi.h.
4101 * Added new local command KEY that is used to set and unset private
4102 keys for channels, set and unset private keys for private messages
4103 with remote clients and to send key agreement requests and
4104 negotiate the key agreement protocol with remote client. The
4105 key agreement is supported only to negotiate private message keys,
4106 it currently cannot be used to negotiate private keys for channels,
4107 as it is not convenient for that purpose.
4109 * Fixed a minor pending callback setting bug in the function
4110 silc_client_get_client_by_id_resolve, now the function works.
4111 Affected file lib/silcclient/idlist.c.
4113 * Added function silc_net_get_local_port to get local bound
4114 port by socket. Added to lib/silcutil/silcnet.[ch].
4116 * Added `sockets' and `sockets_count' fields to the SilcClient
4117 object. They hold the sockets of the listenning sockets in
4118 the client. Listenning sockets may be for example the key
4119 agreement server. Affected file lib/silcclient/client.[ch].
4120 Added functions the silc_client_add_socket and the
4121 silc_client_del_socket. They are exported to the application
4124 * Added ~./silc/clientkeys to support other client's public keys.
4126 * Renamed verify_server_key client operation to verify_public_key
4127 and added one argument to indicate the type of the connection
4128 (server, client etc.).
4130 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Added silc_server_connection_auth_request to handle the
4133 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4134 silcd/packet_receive.[ch].
4136 * Added silc_server_send_connection_auth_request into the
4137 silcd/packet_send.c to send the connection auth request packet.
4139 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4142 * Fixed the public key authentication in responder side in the
4143 server. The `auth_data' pointer includes the SilcPublicKey
4144 not the path to the public key. Affected file silcd/protocol.c.
4146 * Implemented the public key authentication in the initiator side
4147 in the server. Affected file silcd/protocol.c.
4149 * Removed the [RedirectClient] config section from the server
4150 configuration. Is not needed and I don't want to implement it.
4152 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Cleaned up the CMODE command in the server. It now works
4155 correctly and supports all the modes defined in the protocol.
4156 Affected file is silcd/command.c.
4158 * Added `hmac_name' field to the SilcChannelEntry in the server
4159 to hold the default HMAC of the channel. It can be set when
4160 creating the channel (with JOIN command). Affected files
4163 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4164 type to indicate the change of the current cipher and hmac
4165 on the channel. Client can safely ignore the <cipher> argument
4166 (if it chooses to do so) since the CHANNEL_KEY packet will
4167 force the channel key change anyway. The <hmac> argument is
4168 important since the client is responsible of setting the new
4169 HMAC and the hmac key into use.
4171 * Fixed the CMODE command in the client library as well.
4173 * Tested CMODE command in router environment successfully.
4175 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Show the version of the remote client (or server) when connecting
4178 to the server. It is logged to the log file. Affected file
4179 is silcd/protocol.c.
4181 * Fixed the KILLED notify handling in the client library. The
4182 client must be removed from all channels when receiving the
4185 Also, do not remove the client entry when giving the KILL
4186 command but when the KILLED notify is received.
4188 * Removed silc_idlist_find_client_by_nickname from the server.
4189 Not needed anymore. Affected files silcd/idlist.[ch].
4191 * Implemented the CHANNEL_CHANGE notify type handling to the
4192 server. Affected file silcd/server.c.
4196 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Added silc_server_send_notify_invite to send the INVITE
4199 notify between routers.
4201 * Implemented the INVITE command correctly to the server.
4203 * Implemented the INVITE notify type handling in the server.
4205 * Implemented the INVITE command to the client library and on the
4208 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Added function silc_server_get_client_resolve to find the
4211 client entry by ID from all ID lists and then resolve it
4212 (using WHOIS) if it cannot be found. Affected file is
4215 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Implemented the BAN command to the client library.
4219 * The JOIN command in the server now checks the invite list
4222 * Changed the silc_command_reply_payload_encode_va and the
4223 silc_command_payload_encode_va to support that if argument is
4224 NULL it ignores and checks the next argument. Affected file
4225 lib/silccore/silccommand.c.
4227 * Added silc_server_send_notify_ban to send the BAN notify
4228 type between routers.
4230 * Chaned the silc_notify_payload_encode to support that if
4231 argument is NULL it ignores and checks the next argument.
4232 Affected file lib/silccore/silcnotify.c.
4234 * Tested ban lists in router environment successfully.
4236 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Implemented BAN command to the server, in silcd/command.[ch].
4240 * Removed the BAN and INVITE_LIST modes from the CMODE command
4243 * Added function silc_string_match to regex match two strings.
4244 Affected files lib/silcutil/silcutil.[ch].
4246 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Redefined parts of the SilcChannelEntry in the server to support
4249 the new ban and invite lists.
4251 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Redefined the INVITE command. The same command can be used to
4254 invite individuals to the channel but also to manage the invite
4255 list of the channel (to add to and remove from the invite list).
4256 Updated the protocol specs.
4258 * Added new command SILC_COMMAND_BAN that can be used to manage
4259 the ban list of the channel. Updated the protocol specs.
4261 * Removed the channel modes: the SILC_CMODE_BAN and the
4262 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4263 in the CMODE command. The equivalent features are now available
4264 using INVITE and BAN commands. Updated the protocol specs.
4266 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4267 in the network about change in the current ban list. The notify
4268 type is not used by the client.
4270 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4271 support the invite lists.
4273 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Added new function silc_string_regexify that converts string
4276 including wildcard characters into regex string that can
4277 be used by the GNU regex library. Added into the file
4278 lib/silcutil/silcutil.[ch].
4280 Added silc_string_regex_combine to combine to regex strings
4281 into one so that they can be used as one regex string by
4282 the GNU regex library. Added into the file
4283 lib/silcutil/silcutil.[ch].
4285 Added silc_string_regex_match to match two strings. It returns
4286 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4288 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Imported GNU regex to the soruce tree into lib/contrib.
4291 Fixed some compiler warning from the regex.c.
4293 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Fixed MOTD command in the server to work in router environment.
4297 * Fixed the MOTD command in the client library to support
4298 the server argument in the command.
4300 * Added `nickname_len' argument to the silc_idlist_add_client
4301 in the server, as the `nickname' argument may be binary data
4304 * Added silc_idlist_get_channels to return all channels from
4307 * Implemented LIST command to the server. Affected file is
4310 * Implemented the LIST command to the client library and on the
4313 * Added [<user count>] argument to the LIST command reply.
4314 With private channels the user count is not shown.
4316 * Updated TODO and README.
4318 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * The client entry's data.registered must be TRUE even with
4321 global client entry on global client list. The data.registered
4322 is used to check whether the client is anymore in the network,
4323 for example with WHOWAS command so it must be valid.
4325 * Fixed the WHOWAS command in the server. It now actually works
4326 in router environment. Added function into silcd/command_reply.c
4327 silc_server_command_reply_whowas_save.
4329 * Added silc_idlist_purge function to the silcd/idlist.c
4330 to periodically purge the ID Cache.
4332 * Fixed INFO command in the server. It works now in router
4333 environment. Added <server name> argument to the INFO command
4334 reply. Updated the protocol specs.
4336 * Fixed minor bug in silc_idcache_purge to not purge if the
4337 expire value is zero.
4339 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4340 they were buggy because of the WHOWAS information.
4342 * Fixed local command MSG to handle the async resolving of
4343 the remote client properly. It used to fail the first MSG.
4344 Affected file silc/local_command.c.
4346 * Added `data_len' field to SilcIDCache context.
4348 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Update TODO. Todo in commands in the server.
4352 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4354 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4355 used by routers as broadcast packet to inform other routers
4356 about the changed user mode.
4358 Implemented the notify handling in the server. Affected file is
4359 silcd/packet_receive.c. Added the function
4360 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4362 * Added new generic Channel Payload and deprecated the New Channel
4363 Payload. The New Channel Payload is now the generic Channel
4366 * Added new argument `mode' to the silc_server_send_new_channel
4367 as it is required in the Channel Payload now.
4369 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4370 and created a new and real SilChannelPayload to represent the
4371 new generic Channel Payload. Implemented the encode/decode
4372 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4374 * Added silc_server_get_client_channel_list to return the list
4375 of channels the client has joined for WHOIS command reply.
4376 Affected file silcd/server.[ch].
4378 * Implemented the channel list sending in the WHOIS command reply
4379 in server and in the client.
4381 Implemented the channel list displaying on the user interface
4382 as well. Affected file silc/client_ops.c.
4384 * Added silc_channel_payload_parse_list to parse list of Channel
4385 Payloads. It returns SilcDList list of SilcChannelPayloads.
4386 Client for example can use this function to parse the list of
4387 channels it receives in the WHOIS command reply. The caller
4388 must free the list by calling silc_channel_payload_list_free.
4389 Affected files lib/silccore/silcchannel.[ch].
4391 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added one new argument <user mode> to the WHOIS command reply
4394 to return the mode of the user in SILC. Updated the protocol
4397 Implemented it to the server and client.
4399 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Fixed the mode printing on the user interface on joining.
4402 Affected file silc/client_ops.c.
4404 * Implemented the UMODE command and user modes in general to the
4405 client library and to the user interface.
4407 * Implemented the UMODE command to the server.
4409 * The server now sends UNKNOWN_COMMAND error status if client sends
4410 unknown command. Affected file silcd/command.c.
4412 * All server commands now handle the command identifier the right
4413 way when sending the command reply to the client. The client can
4414 use to identify the command replies with the identifier.
4416 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Added silc_server_get_client_route to resolve the route to
4419 the client indicated by the client ID. Affected file is
4422 * Added silc_server_relay_packet as general function to relay
4423 packet to arbitrary destination. This deprecates functions
4424 like _send_private_message_key, _relay_notify etc. Affected
4425 file is silcd/packet_send.[ch].
4427 Removed silc_server_send_key_agreement,
4428 silc_server_send_private_message_key and
4429 silc_server_packet_relay_notify functions from the file
4430 silcd/packet_send.[ch].
4434 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4435 server. Affected file silcd/packet_receive.[ch].
4437 * Implemented the KILL command to the client. Implemented the
4438 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4439 Affected files lib/silcclient/command[_reply].c and
4440 lib/silcclient/client_notify.c. Implemented the KILL notify
4441 printing in the user inteface.
4443 * Fixed a lot silc_parse_nick memory leaks from the client
4444 library in the file lib/silcclient/command.c.
4446 * Changed the silc_server_send_notify_on_channels's `sender'
4447 argument from SilcSocketConnection to SilcClientEntry to
4448 check the sender as entry and not as connection object and not
4449 to send to the client provided as argument. The affected file
4450 is silcd/packet_send.[ch].
4452 * The notify packets that are destined directly to the client used
4453 to not to be processed by the server. Now changed that and the
4454 server processes all notify packets. After relaying the packet
4455 to the client the notify packet is processed in the server.
4457 * The silc_server_free_client_data now checks whether there is
4458 pending outgoing traffic for the client and purges the data to
4459 the network before removing the client entry.
4461 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4464 an client is killed from the SILC Network. Updated the protocol
4467 Added new function silc_server_send_notify_killed to the
4468 silcd/packet_send.[ch].
4470 * Added function silc_server_packet_relay_notify to relay notify
4471 packets that are destined directly to a client. In this case
4472 the server does not process the notify packets but merely relays
4473 it to the client. Affected file silcd/packet_send.[ch].
4475 Added also silc_server_packet_process_relay_notify to check
4476 whereto relay the notify. Affected file is
4477 silcd/packet_receive.[ch].
4479 * Implemented the KILL command to the server.
4483 * Added the backup schema desgined last fall to the protocol
4484 specs for everyone to see. The specification is in the
4485 *-spec-xx.txt draft and the packet type definitions for the
4486 backup routers is in *-pp-xx.txt draft. Thusly, added also
4487 new packet type SILC_PACKET_CELL_ROUTERS.
4489 * A big security problem in the implementation discovered. The
4490 signoff of an client did not cause new channel key generation
4491 which it of course should've done. The channel keys must be
4492 always re-generated when client leaves (or signoffs) the channel.
4493 The silc_server_remove_from_channels funtion now handles
4494 the channel key re-generation.
4496 * Added `sender' argument to the silc_server_send_notify_on_channels
4497 to not to send the client provided as argument. Affected file
4498 silcd/packet_send.[ch].
4500 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Implemented OPER and SILCOPER commands into the server and
4505 * Added silc_auth_verify and silc_auth_verify_data to verify
4506 the authentication directly from the authentication payload.
4507 It supports verifying both passphrase and public key based
4508 authentication. Affected file lib/silccore/silcauth.[ch].
4510 * Added `hash' field to the SilcIDListData structure. It is the
4511 hash negotiated in the SKE protocol. Affected file is
4514 * Slight redesigning of the SilcAuthPayload handling routines.
4515 Do not send SilcPKCS but SilcPublicKey as argument.
4517 * Implemented the public key authentication support to the
4518 serverconfig. The public key is loaded from the provided path
4519 and saved as authentication data to void * pointer. Thus,
4520 changed the unsigned char *auth_data to void *auth_data;
4522 * Fixed SHUTDOWN command to send the reply before the server
4523 is shutdown. :) Affected file silcd/command.c.
4525 * Fixed fatal bug in CONNECT command. The hostname was invalid
4526 memory and server crashed. Affected file silcd/command.c.
4528 * Fixed fatal bug in CLOSE command. The server_entry became
4529 invalid but was referenced later in the command. Affected file
4532 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Fixed fatal bug in failure packet handling. Server ignored
4535 the failure and thus crashed when it came.
4539 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4541 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4542 that the command may be executed only once in (about) 2 seconds.
4543 The old SILC_CF_LAG flag is same but allows command bursts up
4544 to five before limiting.
4546 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4547 server code. Various commands now includes the CF_LAG_STRICT
4548 flag to disallow any kind of miss-use of the command.
4550 * Fixed the silc_buffer_unformat to not to allocate any data
4551 if the length of the data is zero. It used to allocate the
4552 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4554 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4556 * Changed the format of AdminConnection configuration section
4557 in the server. Added username of the admin to the format.
4558 Affected files silcd/serverconfig.[ch].
4560 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4561 to return admin configuration data by host, username and/or
4564 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Implemented WHOWAS command to the server. Added the functions:
4568 silc_server_command_whowas_parse,
4569 silc_server_command_whowas_send_reply,
4570 silc_server_command_whowas_from_client and
4571 silc_server_command_whowas_from_server
4573 * Added <Client ID> argument to the WHOWAS command reply. Updated
4574 the protocol specs accordingly.
4576 * Implemented WHOWAS command and command_reply to the client
4579 Implemented the WHOWAS printing on the user interface.
4581 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Added new argument to the WHOWAS command reply, the real name.
4584 It is an optional argument. Updated the protocol specs.
4586 * Added SilcIDCacheDestructor callback that is registered when
4587 the SilcIDCache is allocated. The callback is called when
4588 an cache entry in the ID Cache expires, or is purged from the
4589 cache. Added into lib/silccore/idcache.[ch].
4591 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4592 to destruct the client entries when the cache entry expires.
4593 Other ID Cache's in server and in the client library ignores
4596 * If the ID Cache entry's `expire' field is zero then the entry
4597 never expires. Added boolean `expire' argument to the
4598 silc_idcache_add function in the lib/silccore/idcache.[ch].
4599 If it is TRUE the default expiry value is used.
4601 * Added silc_server_free_client_data_timeout that is registered
4602 when client disconnects. By default for 5 minutes we preserve
4603 the client entry for history - for WHOWAS command.
4605 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Added support to the server to enforce that commands are not
4608 executed more than once in 2 seconds. If server receives
4609 commands from client more frequently, timeout is registered
4610 to process the commands. Affected file silcd/command.c.
4611 Added new function silc_server_command_process_timeout.
4613 * Changed NICK_NOTIFY handling in client library to check that
4614 if the client's nickname was changed, so there is no need to
4615 resolve anything from the server.
4617 * Removed error printing from the WHOIS and IDENTIFY commands.
4618 If error occurs then it is ignored silently in the client library.
4619 The application, however, may map the received error to
4620 human readable error string. The application currently maps
4621 the NO_SUCH_NICKNAME error to string.
4623 * Made the command status message public to the application. Moved
4624 them from lib/silcclient/command_reply.c to
4625 lib/silcclient/command_reply.h. The application can map the
4626 received command status to the string with the
4627 silc_client_command_status_message function.
4629 * Added check to the server to check that client's ID is same
4630 as the Source ID in the packet the client sent. They must
4633 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Added dist-bzip hook to the Makefile.am to make bzip2
4636 compressed distributions.
4638 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Server now enforces the maximum length for the nickname and
4641 the channel as protocol specification dictates. 128 bytes for
4642 nickname and 256 bytes for channel name.
4644 * Moved the WHOIS printing to the application. The client libary
4645 does not print out the WHOIS information anymore, the application
4646 must do it. Renamed silc_client_command_reply_whois_print to
4647 the silc_client_command_reply_whois_save.
4649 The client's idle time is also sent to the application now, and
4650 the idle is shown on screen.
4652 * Added silc_client_command_reply_identify_save to save the
4653 received IDENTIFY entries.
4655 * Do not check for channel private keys in message sending and
4656 reception if the channel does not have the PRIVKEY mode set.
4657 Affected file lib/silclient/client_channel.c.
4659 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4662 just surfaced after chaning the JOIN procedure.
4664 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4666 * Added silc_client_get_clients_by_list to get client entries
4667 from Client ID list, that is returned for example by JOIN
4668 and USERS command replies. The application should use this
4669 function for example when JOIN command reply is received to
4670 resolve the clients already on the channel (library does not
4671 do that anymore as USERS command reply is not used in the JOIN
4672 procedure anymore). Affected files lib/silcclient/silcapi.h and
4673 lib/silcclient/idlist.c.
4675 * JOIN command reply and USERS command reply returns now SilcBuffer
4676 pointers instead of unsigned char pointers when returning
4677 the client list and mode list.
4679 * Added <Client ID> argument to the JOIN command reply, mainly
4680 for the server to identify for which client the command was
4681 originally sent. Updated protocol specs accordingly.
4683 * Added SilcDlist private_key pointer to the SilcChannelEntry
4684 in the client to support the channel private keys. Affected
4685 file is lib/silcclient/idlist.h.
4687 * Added SilcChannelPrivateKey argument to the function
4688 silc_client_send_channel_message so that application can choose
4689 to use specific private ke if it wants to. If it is not provided,
4690 the normal channel key is used, unless private keys are set.
4691 In this case the first (key that was added first) is used
4692 as the encryption key.
4694 * Implemented the support for channel private key handling.
4695 Implemented the following functions:
4697 silc_client_add_channel_private_key,
4698 silc_client_del_channel_private_keys,
4699 silc_client_del_channel_private_key,
4700 silc_client_list_channel_private_keys and
4701 silc_client_free_channel_private_keys
4703 Affected file lib/silcclient/client_channel.c.
4705 * Added the support for the private keys in the channel message
4706 sending and encryption and in the message reception and
4707 decryption. Affected funtions are
4708 silc_client_send_channel_message and silc_client_channel_message.
4710 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added SKE's key verify callback to the client library's
4713 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4715 * Removed the statement that server (or router) must send USERS
4716 command reply when joining to the channel so that the client
4717 knows who are on the channel. Instead, the client list and
4718 client's mode list is now sent in the JOIN command reply to the
4719 client who joined channel. This is better solution.
4721 * Added function silc_server_get_users_on_channel and function
4722 silc_server_save_users_on_channel to the silcd/server.[ch].
4724 * Removed function silc_server_command_send_users from the
4727 * Do not show topic on the client library anymore. The topic is
4728 sent in the command reply notify to the application and the
4729 application must show the topic now.
4731 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4733 * Added client searching by nickname hash into the IDENTIFY and
4734 WHOIS commands in the server as they were clearly missing from
4735 them. Affected file is silcd/command.c.
4737 * Fixed a bug in private message receiving in the client library.
4738 The remote ID was freed and it wasn't supposed, now it is
4741 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Minor fix to the channel payload; allocate the data area, as it
4744 needs to be of specific length.
4746 * If the key agreement port is zero then the operating
4747 system will define the bound port. Affected files are
4748 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4750 * Added new function silc_channel_payload_decrypt into the file
4751 lib/silccore/silcchannel.[ch].
4753 * Moved the channel message etc, check from silc_packet_decrypt
4754 to applications. The library calls now a generic
4755 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4756 when the packet is either normal or special. This was done to
4757 allow more wide range of checking that was not allowed when
4758 the code was in library. Now applications can do virtually any
4759 checks to the packet and return to the library the decision how
4760 the packet should be processed. Affected files are
4761 lib/silccore/silcpacket.[ch].
4763 Added silc_server_packet_decrypt_check to the server and
4764 silc_client_packet_decrypt_check to the client library.
4766 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4767 to send with specified source and destination information.
4769 * Channel message delivery between routers was broken after the
4770 channel key distribution was fixed earlier. The channel key
4771 was used be to distributed to other routers as well which is not
4772 allowed by the protocol. Now this is fixed and channel keys
4773 really are cell specific and the channel message delivery between
4774 routers comply with the protocol specification.
4776 * Fixed various commands in server to check also the global list
4777 for the channel entry and not just the local list. The affected
4778 file silcd/command.c.
4780 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Added assert()s to buffer formatting and unformatting routines
4783 to assert (if --enable-debug) when error occurs. Affected
4784 file: lib/silcutil/silcbuffmt.c.
4786 * Changed to auto-reconnect to check whether the remote host is
4787 router and register the re-connect timeout if it is. It used
4788 to check that whether we are normal server, but router must do
4789 auto-reconnect with another router as well. Affected file
4792 * Removed the [<key len>] option from CMODE command as the cipher
4793 name decides the key length, nowadays. See the defined ciphers
4794 from the protocol specification.
4796 * Added [<hmac>] option to the CMODE command to define the HMAC
4797 for the channel. Added SILC_CMODE_HMAC channel mode.
4799 * Added [<hmac>] option for the JOIN command so that user can
4800 select which HMAC is used to compute the MACs of the channel
4803 * Added Hmac field to the Channel Message Payload. The integrity
4804 of plaintext channel messages are now protected by computing
4805 MAC of the message and attaching the MAC to the payload. The
4806 MAC is encrypted. Now, it is clear that this causes some
4807 overhead to the size of the packet but rationale for this is that
4808 now the receiver can verify whether the channel message decrypted
4809 correctly and also when private keys are set for the channel the
4810 receiver can decrypt the packet with several keys and check from
4811 the MAC which key decrypted the message correctly.
4813 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4814 lib/silccrypt/silccipher.[ch].
4816 * Added silc_hash_len to return the digest length into the
4817 lib/silcrypt/silchash.[ch].
4819 * Rewrote parts of Silc Channel Payload interface in the
4820 lib/silccore/silcchannel.[ch]. The encode function now also
4821 encrypts the packet and parse function decrypts it.
4823 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Fixed a minor formatting bug in the SKE's key material processing.
4826 It actually might have processed the keys wrong way resulting
4829 * Redefined the mandatory HMAC algorithms and added new algorithms.
4830 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4831 and hmac-md5 truncated to 96 bits. The mandatory is now
4832 hmac-sha1-96. Rest are optional (including the one that used
4833 to be mandatory). Rationale for this is that the truncated HMAC
4834 length is sufficient from security point of view and can actually
4835 make the attack against the HMAC harder. Also, the truncated
4836 HMAC causes less overhead to the packets. See the RFC2104 for
4839 * Added new [hmac] configuration section. The SKE used to use
4840 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4841 is of course wrong. The official names that must be proposed in
4842 the SKE are the ones defined in the protocol specification
4843 (hmac-sha1-96 for example). The user can configure any hmac
4844 using any hash function configured in the [hash] section. At
4845 least, the mandatory must be configured.
4847 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4849 * Added HMAC list to the SKE proposal list. It has now both
4850 hash algorithm list and HMAC list. This makes the protocol
4851 incompatible with previous versions. The SKE now seems to work
4852 the way it is supposed to work, for the first time actually.
4854 * Defined plain Hash algorithms to the protocol specification.
4857 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Implemented support for key agreement packets into the server.
4860 Added functions silc_server_key_agreement and
4861 silc_server_send_key_agreement. Other than these functions,
4862 server has nothing to do with this packet.
4864 * Added support for private message key packets into the server.
4865 Added functions silc_server_private_message_key and
4866 silc_server_send_private_message_key.
4870 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4871 called in the protocol's final callback instead in the END
4872 protocol state. This makes a little more sense and in the same
4873 time in client we can use the same protocol routines for normal
4874 key exchange and to key agreement packet handling as well.
4876 * Added to both client's and server's KE protocol context the
4877 SilcSKEKeyMaterial pointer to save the key material. We will
4878 bring the key material to the protocol's final callback by doing
4879 this. The final callback must free the key material.
4881 * Added SKE's packet_send callback into client's KE protocol
4882 context so that the caller can choose what packet sending function
4883 is used. This way we can use different packet sending when
4884 doing normal SKE when doing key agreement packet handling (in
4885 the key agreement packet handling we do not want to encrypt
4888 * Implemented the responder side of the key agreement routines
4889 in the client. The client can now bind to specified port and
4890 accept incoming key negotiation. The key material is passed
4891 to the application after the protocol is over.
4893 * Implemented the processing of incoming Key Agreement packet
4894 in the client. Added function silc_client_key_agreement to
4897 * Implemented the intiator side of the key agreement routines
4898 in the client. The client can now initiate key agreement with
4899 another remote client. The key material is passed to the
4900 application after the protocol is over.
4902 * Created client_keyagr.c to include all the key agreement
4905 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4906 SILC_TASK_CALLBACK except that it is not static.
4908 * Created client_notify.c and moved the Notify packet handling
4909 from the client.[ch] into that file.
4911 * Created client_prvmsg.c and moved all private message and
4912 private message key routines from the client.[ch] into that file.
4914 * Create client_channel.c and moved all channel message and
4915 channel private key routines from the client.[ch] into that file.
4917 * Changed silc_client_get_client_by_id_resolve to resolve with
4918 WHOIS command instead of IDENTIFY command, in the file
4919 lib/silclient/idlist.c.
4921 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Implemented the SKE's responder side to the Client library.
4925 * When FAILURE is received to the protocol do not trust it
4926 blindly. Register a timeout to wait whether the remote closes
4927 the connection as it should do it, only after that process the
4928 actual failure. This was changed to both client and server.
4930 * Added client_internal.h to include some of the structures
4931 there instead of client.h in lib/silcclient/.
4933 * Added function silc_task_unregister_by_callback to unregister
4934 timeouts by the callback function.
4936 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Some "Incomplete WHOIS info" errors has been appearing on the
4939 log files. Took away the entry->userinfo check from WHOIS
4940 reply sending. The entry->userinfo is now " " if client did not
4941 provide one. I thought this was fixed earlier but something
4942 is wrong still. Let's see if the error still appears.
4944 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Fixed a minor bug in the login when the channel key is
4947 re-generated in the server. It used to generate the key in
4948 wrong order and thus caused problems in the channel traffic.
4950 * Fixed a minor bug in channel key distsribution after
4951 KICK command. The key was not sent to the router even though
4954 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Added silc_ske_process_key_material_data as generic routine
4957 to process any key material as the SILC protocol dictates. The
4958 function is used by the actual SKE library but can be used by
4959 applications as well. This relates to the private message keys
4960 and the channel private keys since they must be processed the
4961 same way the normal SILC session keys. The protocol dictates
4962 this. Affected files: lib/silcske/silcske.[ch].
4964 Added also silc_ske_free_key_material to free the
4965 SilcSKEKeyMaterial structure.
4967 * Defined silc_cipher_set_key function to set the key for
4968 cipher without using the object's method function. The affected
4969 files: lib/silccrypt/silccipher.[ch].
4971 * Implemented silc silc_client_add_private_message_key,
4972 silc_client_add_private_message_key_ske,
4973 silc_client_del_private_message_key,
4974 silc_client_list_private_message_keys and
4975 silc_client_free_private_message_keys functions in the
4978 Added functions silc_client_send_private_message_key to send
4979 the Private Message Key payload and silc_client_private_message_key
4980 to handle incoming Private Message Key payload.
4982 * Added Cipher field to the Private Message Key payload to set
4983 the cipher to be used. If ignored, the default cipher defined
4984 in the SILC protocol (aes-256-cbc) is used.
4986 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Removed lib/silcclient/ops.h file.
4990 Redefined parts of the SILC Client Library API. Created new
4991 file silcapi.h that deprecates the ops.h file and defines the
4992 published Client Library API. Defined also private message key
4993 API and channel private key API into the file.
4995 This is the file that the application must include from the
4996 SILC Client Library. Other files need not be included by
4997 the application anymore.
4999 * Added new key_agreement client operation callback and also
5000 defined the Key Agreement library API for the application.
5002 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5005 is used by clients to request key negotiation between another
5006 client in the SILC network. If the negotiation is started it
5007 is performed using the SKE protocol. The result of the
5008 negotiation, the secret key material, can be used for example
5009 as private message key.
5011 Implemented the Key Agreement payload into the files
5012 lib/silccore/silauth.[ch].
5014 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * Redefined ciphers for the SILC protocol. Added some new ciphers
5017 and defined the key lengths for the algorithms. Changed the
5018 code accordingly. The default key length is now 256 bits.
5020 * Fixed SKE key distribution function silc_ske_process_key_material
5021 when the key length is more than 128 bits. The default key
5022 length in SILC is now 256 bits.
5024 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5025 to indicate unsupported algorithm.
5027 * Renamed rijndael.c to aes.c and all functions as well.
5029 * Fixed a long standing channel key setting bug in client library.
5030 Weird that it has never surfaced before.
5032 * Fixed bug in channel deletion. If the entire channel is removed
5033 then it must also delete the references of the channel entry
5034 from the client's channel list as the client's channel entry and
5035 the channel's client entry share same memory.
5037 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Implemented CONNECT and SHUTDOWN commands in the client.
5041 * Implemented CLOSE command to the client.
5043 * Added the function silc_idlist_find_server_by_name into the
5044 files silcd/idlist.[ch].
5046 Added the function silc_idlist_find_server_by_conn into the
5047 files silcd/idlist.[ch].
5049 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * DIE command was renamed to SHUTDOWN. Updated the both code
5054 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5055 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5057 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5060 * Added function silc_server_create_connection function to create
5061 connection to remote router. My server implementation actually
5062 does not allow router to connect to normal server (it expects
5063 that normal server always initiates the connection to the router)
5064 so the CONNECT command is only good for connecting to another
5067 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5070 or some other client was kicked from the channel.
5072 Implemented the handling of the notify type to both client
5075 Implemented silc_server_send_notify_kicked to send the KICKED
5076 notify. It is used to send it to the server's primary router.
5078 * Implemented the KICK command into server and client.
5080 * Added `query' argument to the silc_idlist_get_client function
5081 to indicate whether to query the client from server or not if
5084 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5085 to indicate that the client is not channel founder.
5089 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Removed the rng context from SilcPacketContext structure and
5092 changed that the packet routine uses the Global RNG API.
5094 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5096 * Added support for quit message that client can "leave" on the
5097 channel when it quits the SILC. It is ditributed inside the
5098 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5100 Added silc_server_free_client_data that will take the
5101 signoff message as argument.
5103 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5105 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Updated parts of the protocol specification to keep it up
5110 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5113 payloads in one packet.
5115 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5116 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5117 use now the new List flag.
5119 * Also deprecated the following packet types: REPLACE_ID,
5120 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5122 * Added list support for Notify packet in server.
5124 * Added silc_server_send_notify_channel_change to send the
5125 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5126 the silc_server_send_replace_id.
5128 * Added silc_server_send_notify_nick_change to send the
5129 NICK_CHANGE notify type. Deprecates the function
5130 silc_server_send_replace_id.
5132 * Added silc_server_send_notify_join to send the JOIN notify type.
5133 Deprecates the function silc_server_send_new_channel_user.
5135 * Added silc_server_send_notify_leave to send LEAVE notify type.
5136 Deprecates the function silc_server_send_remove_channel_user.
5138 * Added silc_server_send_notify_cmode and
5139 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5140 types. Deprecates the silc_server_send_set_mode function.
5142 * Added SERVER_SIGNOFF notify type to indicate that server has
5143 quit. This means that all clients on the channel from that
5144 server will drop. This can be also used when netsplit happens.
5146 Deprecated REMOVE_ID packet type since it is not needed anymore
5149 Added silc_server_send_notify_server_signoff to send the
5150 SERVER_SIGNOFF notify type. Deprecates the function
5151 silc_server_send_remove_id.
5153 Added also silc_server_send_notify_signoff to send the
5154 SIGNOFF notify type.
5156 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5157 SILC protocol from this day on. Changed the protocol
5158 specification as well.
5160 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5161 notify type. It is used between routers to notify about
5162 topic changes on a channel.
5164 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5167 * Partly updated the protocol specification to comply with the
5168 changes now made. It is still though a bit outdated.
5170 * The JOIN notify type now takes one extra argument <Channel ID>.
5171 The packet used to be destined to the channel but now the
5172 JOIN type may be sent as list thus it is impossible to
5173 destine it to any specific channel. By adding this argument
5174 it is again possible.
5176 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5178 * Added CREDITS file. The CHANGES and CREDITS file will appear
5179 in the distribution as well.
5181 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5184 types in the server's silcd/packet_receive.c.
5186 * Implemented CMODE and CUMODE to work in router environment.
5188 * Fixed minor encoding and decoding buglet from the
5189 lib/silccore/silcmode.c.
5191 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5194 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5196 * Changed all SilcConfigServer* and silc_config_server* to
5197 SilcServerConfig* and silc_server_config*, respectively.
5200 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Associated the ID (client or server ID) to the Authentication
5203 Payload to avoid any possibility of forging. Updated the
5204 protocol specification and the code accordingly.
5206 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * The RSA key length is now save to the RsaKey context in the
5209 key generation process in lib/silccrypt/rsa.c. The key length
5210 is now used to figure out the maximum size of the block allowed
5211 to be encrypted/signed.
5213 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5214 is equivalent to the silc_mp_mp2bin but does not allocate any
5217 * Changed silc_mp_mp2bin API to take length argument. If it is
5218 non-zero then the buffer is allocated that large. If zero, then
5219 the size is approximated using silc_mp_sizeinbase, which however
5222 * Created Global RNG API which is global RNG that application can
5223 initialize. After initializing, any routine anywhere in the
5224 code (including library) can use RNG without allocating a new
5225 RNG object. This was done to allow this sort of use of the
5226 RNG in code that has no chance to allocate RNG object. All
5227 applications currently allocate this and many routines in the
5228 library use this. Affected file lib/silccrypt/silcrng.[ch].
5230 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5231 it to use the Global RNG API.
5233 * Defined Authentication Payload into protocol specification that
5234 is used during SILC session to authenticate entities. It is
5235 used for example by client to authenticate itself to the server
5236 to obtain server operator privileges.
5238 Implemented this payload into the lib/silccore/silcauth.[ch].
5239 Implemented also routines for public key based authentication
5240 as the new protocol specification dictates.
5242 Moved definitions of different authentication methods from
5243 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5245 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5246 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5247 silc_pkcs_verify_with_hash functions into the file
5248 lib/silccrypt/silcpkcs.[ch].
5250 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * The client entry's userinfo pointer must be always valid.
5253 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5254 will fail since it requires the userinfo. Now, the userinfo
5255 is allocated as "" if actual userinfo does not exist. Actually,
5256 it must exist and it is totally Ok to drop client connections
5257 that does not announce the userinfo. However, we will make
5258 this workaround for now.
5260 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5261 to return the remote port by socket.
5263 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5266 SILC_SERVER_PENDING_EXEC and added an new macro
5267 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5268 data or when error occurs while processing the pending command.
5270 Added new argument `destructor' into silc_server_command_pending
5271 and to the SilcServerCommandPending object. This destructor is
5272 now called after calling the pending callback or if error occurs
5273 immediately. If error occurs the actual pending callback won't
5274 be called at all - only the destructor. The destructor may be
5275 NULL if destructor is not needed.
5277 All this applies for client library code as well. Similar
5278 changes were made there as well for the pending commands.
5280 In the client, the application must now allocate the
5281 SilcClientCommandContext with the silc_client_command_alloc
5284 * Added reference counter to the SilcServerCommandContext. Added
5285 function silc_server_command_alloc and silc_server_command_dup
5288 Same type of functions added to the client library for the same
5291 * Removed the cmd_ident from IDListData away since it is now
5292 global for all connections. It is the command identifier used
5293 in command sending and with pending commands. The affected file
5296 * Added reference counter to the SilcSocketConnection objecet to
5297 indicate the usage count of the object. The object won't be
5298 freed untill the reference counter hits zero. Currently only
5299 server uses this, and client ignores it. The client must be
5300 set to use this too later. The affected files are
5301 lib/silccore/silcsockconn.[ch]. Added also the function
5302 silc_socket_dup to increase the reference counter.
5304 This was mainly added because it is possible that the socket
5305 is removed underneath of pending command or other async
5306 operation. Now it won't be free'd and proper DISCONNECTING
5307 flags, etc. can be set to avoid sending data to connection that
5308 is not valid anymore.
5310 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5311 the connection. After that it sets SILC_SET_DISCONNECTED.
5312 It is, however, possible that the socket data is not still freed.
5313 The silc_server_packet_process now checks that data is not
5314 read or written to connection that is DISCONNECTED. The socket
5315 get's freed when the reference counter hits zero.
5317 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Changed the client operation API: channel_message operation's
5320 `sender' is now the client entry of the sender, not the nickname
5321 and the `channel' is the channel entry, not the channel name.
5323 In the private_message operation the `sender' is now also the
5324 client entry of the sender not the nickname.
5326 Affected file is lib/silcclient/ops.h and all applications
5327 using the client operations.
5329 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Moved the calling of ops->connect() from connect_to_server_final
5332 into receive_new_id functin since that is the point when the
5333 client is actually allowed to send traffic to network. The
5334 affected file is lib/silcclient/client.c.
5336 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5339 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5340 (if needs broadcasting) instead of broadcasting the packets one
5341 by one which would make a burst in the network traffic.
5343 * Added `broadcast' argument to the functions in silcd/server.[ch]
5344 silc_server_create_new_channel[_with_id] to indicate whether
5345 to send New Channel packet to primary router.
5347 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added new function into the silcd/server.[ch] files:
5350 silc_server_create_new_channel_with_id to create new channel with
5351 already existing Channel ID.
5353 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5354 lib/silccore/silcpacket.h. This packet is used t send list of
5355 Set Mode payloads inside one packet. Server uses this to set
5356 the modes for the channels and clients on those channels, that it
5357 announced to the router when it connected to it. The protocol
5358 specification has been updated accordingly.
5360 * The silc_server_new_channel did not handle the packet coming
5361 from normal server as it normally does not send that. However,
5362 when it announces its channels it does send it. Implemented
5363 the support for that.
5365 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5366 into the file lib/silccore/id.h.
5368 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Fixed memory leaks in the functions silc_idlist_del_client,
5371 silc_idlist_del_channel and silc_idlist_del_server in the file
5372 silcd/idlist.c. All of those leaked like a sieve.
5374 * Fixed some small memory leaks in the client's function
5375 silc_client_notify_by_server.
5377 * Added functions into silcd/server.c: silc_server_announce_clients,
5378 silc_server_announce_channels and silc_server_announce_server.
5379 These functions are used by normal and router server to announce
5380 to its primary router about clients, channels and servers (when
5381 router) that we own. This is done after we've connected to the
5384 These functions effectively implements the following packet types:
5385 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5386 and SILC_PACKET_NEW_ID_LIST.
5388 * Added new functions into the silcd/packet_receive.[ch]:
5389 silc_server_new_id_list, silc_server_new_channel_list and
5390 silc_server_new_channel_user_list to handle the incoming
5391 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5393 * Added support of changing Channel ID in the function
5394 silc_server_replace_id. If the server that announces a channel
5395 to the router already exists in the router (with same name but
5396 with different Channel ID), router is responsible to send
5397 Replace ID packet to the server and force the server to change
5398 the Channel ID to the one router has.
5400 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5401 client that the Channel ID has been changed by the router. The
5402 normal server sends this to the client. Client must start using
5403 the new Channel ID as the channel's ID.
5405 Implemented handling of this new type into lib/silcclient/client.c
5406 into the function silc_client_notify_by_server.
5408 * Added new function silc_idlist_replace_channel_id into the files
5409 silcd/idlist.[ch] to replace the Channel ID.
5411 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Call silc_server_command_identify_check always when processing
5414 the IDENTIFY command in silcd/command.c
5416 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5419 send keepalive packets. The packet can be sent by clients,
5420 servers and routers.
5422 Added function silc_socket_set_heartbeat into the file
5423 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5424 If not set, the heartbeat is not performed. The actual
5425 heartbeat is implemented in the low level socket connection
5426 library. However, application is responsible of actually
5429 Added silc_server_send_heartbeat to send the actual heartbeat
5430 packet into silcd/packet_send.[ch]. Server now performs
5431 keepalive with all connections.
5433 * Added silc_task_get_first function into lib/silcutil/silctask.c
5434 to return the timeout task with shortest timeout. There was a bug
5435 in task unregistration that caused problems. TODO has been
5436 updated to include that task system must be rewritten.
5438 * The client library will now resolve the client information when
5439 receiving JOIN notify from server for client that we know but
5440 have incomplete information.
5442 * Rewrote parts of silc_server_remove_from_channels and
5443 silc_server_remove_from_one_channel as they did not remove the
5444 channel in some circumstances even though they should've.
5446 * Encryption problem encountered in server:
5448 The LEAVE command used to send the Channel Key packet to the
5449 router immediately after generating it. However, the code
5450 had earlier sent Remove Channel user packet but not immediately,
5451 ie. it was put to queue. The order of packets in the router
5452 was that Channel Key packet was first and Remove Channel User
5453 packet was second, even though they were encrypted in the
5454 reverse order. For this reason, MAC check failed. Now, this
5455 is fixed by not sending the Channel Key packet immediately but
5456 putting it to queue. However, this is more fundamental problem:
5457 packets that are in queue should actually not be encrypted
5458 because packets that are sent immediately gets encrypted
5459 actually with wrong IV (and thus MAC check fails). So, packets
5460 that are in queue should be encrypted when they are sent to
5461 the wire and not when they put to the queue.
5463 However, the problem is that the current system has not been
5464 designed to work that way. Instead, the packet is encrypted
5465 as soon as possible and left to the queue. The queue is then
5466 just purged into wire. There won't be any fixes for this
5467 any time soon. So, the current semantic for packet sending
5470 o If you send packet to remote host and do not force the send
5471 (the packet will be in queue) then all subsequent packets to the
5472 same remote host must also be put to the queue. Only after the
5473 queue has been purged is it safe again to force the packet
5476 o If you send all packets immediately then it safe to send
5477 any of subsequent packets through the queue, however, after
5478 the first packet is put to queue then any subsequent packets
5479 must also be put to the queue.
5481 Follow these rules and everything works fine.
5483 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Added new function silc_server_remove_clients_by_server to
5486 remove all client entries from ID list when the server connection
5487 is lost. In this case it is also important to invalidate all
5488 client entires as they hold the invalid server entry. This
5489 fixes fatal bug when server has lost connection and will reconnect
5492 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Made some sanity checks to silc_server_daemonise like to check
5495 whether the requested user and group actually exists.
5497 * Added sanity check to SKE's silc_ske_responder_finish to check
5498 that the public and private key actually is valid.
5500 * Invalidate the client's nickname when receiving Replace ID
5501 packet and the Client ID is being replaced. This means that the
5502 server will query the nickname if someone needs it (client)
5505 * Sort the ID Cache in client library when the ID Cache data
5506 has changed (needs sorting).
5508 * Do not allow for SILC client to create several connections to
5509 several servers. The client does not support windows right now
5510 and generating multiple connections causes weird behaviour.
5512 Irssi-silc client does support windows and can handle several
5513 connections without problems, see: www.irssi.org and SILC plugin.
5515 * Fixed some places where client was added to the IDList. The
5516 rule of thumb is following (in order to get everything right):
5517 If the client is directly connected local client then the
5518 `connection' argument must be set and `router' argument must be
5519 NULL to silc_idlist_add_client function. If the client is not
5520 directly connected client then the `router' argument must
5521 bet set and the `connection' argument must be NULL to the
5522 silc_idlist_add_client function.
5524 * The funtion silc_server_packet_send_local_channel actually did
5525 not check whether the client was locally connected or not. It
5526 does that now. Fixed a bug related to LEAVE command.
5528 * Fixed Remove Channel User payload parsing bug in server's
5529 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5531 * The server's silc_server_save_channel_key now checks also the
5532 global ID list for the channel as it might not be in the local
5533 list. Fixed a bug related to LEAVE command.
5535 * Is this the end of the [<unknown>] buglet that has been lurking
5536 around for a long time? A little for loop fix in server's
5537 silc_server_command_whois_parse that is used by both IDENTIFY
5538 and WHOIS command. At least, this was a clear bug and a cause
5539 of one type of [<unknown>] buglet.
5541 * WHOIS and IDENTIFY commands call the function
5542 silc_server_command_[whois/identify]_check function even if
5543 we are not router server.
5545 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Added --with-gmp configuration option. If set the GMP
5548 is always compiled in the SILC source tree. If not set then
5549 it is checked whether the system has the GMP3 installed. If
5550 it has then the GMP won't be compiled (the system's headers
5551 and library is used), if it doesn't have it then the GMP is
5552 compiled in the SILC source tree.
5554 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Changed RSA private exponent generation to what PKCS #1
5557 suggests. We try to find the smallest possible d by doing
5558 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5559 not security fix but optimization.
5561 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Added new config entry [Identity] to fork the server and run
5564 it as specific user and group. A patch from Bostik.
5566 * Imported Dotconf configuration library into lib/dotconf.
5567 This will be used to create the SILC configuration files later.
5568 It will appear in the distsribution after this commit.
5570 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * A big code auditing weekend happening. Auditing code for
5573 obvious mistakes, bugs and errors. Also, removing any code
5576 Removed files for being obsolete:
5578 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5579 inline in the file lib/silcutil/silcbuffer.h)
5581 o lib/silcutil/silcbufutil.c (the header has inline versions)
5583 Changed code to fix possible error conditions:
5585 o The buffer formatting routines now check that the destination
5586 buffer really has enough space to add the data. This applies for
5587 both buffer formatting and unformatting
5588 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5589 unformatting was changed to accomodate following rules:
5590 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5591 sent to the function while XXX_*STRING will not allocate or copy
5592 the data into the buffer. Instead it sets the pointer from the
5593 buffer into the pointer sent as argument (XXX_*STRING used to
5594 require that the pointer must be allocated already). This change
5595 makes this whole thing a bit more consistent and more optimized
5596 (note that the data returned in the unformatting with XXX_*STRING
5597 must not be freed now). The routines return now -1 on error.
5599 o Tried to find all code that use buffer_format and buffer_unformat
5600 and added return value checking to prevent formatting and
5601 especially unformatting errors and possible subsequent fatal
5604 o Changed ske->x and ske->KEY to mallocated pointers in
5605 lib/silcske/silcske.h. Fixed possible data and memory leak.
5607 o Added return value checking to all *_parse* functions. Fixed
5608 many memory leaks as well.
5610 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5611 so that buffer overflows would not happen. All code now also
5612 checks the return value as it can fail.
5614 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added reconnection support to server if the normal server looses
5617 its connection to the router (for example if router is rebooted).
5618 The server performs normal reconnection strategy implemented
5619 to the server. Affected file silcd/server.c.
5621 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Added new packet type SILC_PACKET_SET_MODE that is used to
5624 distribute the information about changed modes (for clients,
5625 channels and clients channel modes) to all routers in the
5626 network. Updated the protocol specification accordingly.
5628 Added functions into silcd/packet_send.c and
5629 silcd/packet_receive.c: silc_server_send_set_mode,
5630 silc_server_set_mode.
5632 Added new files silcmode.[ch] into lib/silccore that implements
5633 the encoding and decoding of Set Mode Payload. Added new type
5634 SilcSetModePayload. Moved the definitions of different modes
5635 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5637 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Oops, a little mistake in server's connection authentication
5640 protocol. The protocol is not ended with FAILURE but with
5641 SUCCESS if the authentication is Ok. :) Affected file is
5644 * Implemented NICK_CHANGE notify handling in server in the file
5645 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5646 the local clients on the channel. After the changing nickname
5647 in router environment snhould work and the [<unknown>] nickname
5648 should appear no more.
5650 The silc_server_replace_id function that receives the Replace ID
5651 payload now sends the NICK_CHANGE notify type also in the file
5652 silcd/packet_receive.c
5654 * Changed WHOIS and IDENTIFY command to support the maximum amount
5655 of arguments defined in protocol specs (3328 arguments). This
5656 fixed a bug that caused problems when there were more than three
5659 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5661 * Added extra parameter, command identifier, to the
5662 silc_client_send_command so that explicit command identifier
5665 Changed that ID list routines uses specific command identifier
5666 when sending WHOIS/IDENTIFY requests to the server so that they
5667 can be identified when the reply comes back.
5669 Affected files lib/silcclient/command.[ch],
5670 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5672 * Added `sender' argument to silc_server_packet_send_to_channel
5673 to indicaet the sender who originally sent the packet to us
5674 that we are now re-sending. Ignored if NULL. Affected file
5675 silcd/packet_send.[ch].
5677 * Added some server statistics support in silcd/server_internal.h
5678 SilcServerStatistics structure and around the server code. Also
5679 send some nice statistics information when client is connecting
5682 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Fixed channel ID decoding in server's JOIN command reply in
5685 silcd/command_reply.c
5687 * Fixed braodcasting of replace ID payload to not to send it if
5688 we are standalone server in silcd/packet_receive.c.
5690 * Fixed all channel message sending routines to not to send
5691 packets to clients that has router set, since they are routed
5692 separately in the same function earlier. Affects file
5693 silcd/packet_send.c and all channel packet sending functions.
5695 * In USERS reply, res_argv[i] are not allocated, the table
5696 is allocated. Thus changed that free the table, not its
5699 * In server's whois_check and identify_check if the client is
5700 locally connected do not send any WHOIS commands - they are not
5703 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Fixed some minor bugs in client when sending WHOIS command. The
5706 arguments was in wrong order.
5708 * Removed statis function add_to_channel from server in
5709 silcd/command.c that was previously used with the joining but
5712 * Tested USERS command in router environment successfully with two
5713 routers, two servers and two clients.
5715 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Reorganized the USERS command and command reply in client library
5718 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5719 When the command is given by user we register a pending command
5720 callback that will reprocess the command after the reply has been
5721 received from the server. When reprocessing the packet we then
5722 display the information. Thus, the USERS information is displayed
5723 now in the command callback instead of in the command reply
5724 callback. The processing of the command is same as previously
5725 when server has sent the command reply in the JOINing process.
5727 * Added to USERS command in silcd/command_reply.c to join the client,
5728 we didn't use to know about, to the channel after we've created
5729 a client entry for it. Also, for clienet we did know already still
5730 check whether it is on the channel or not and add it if not.
5732 * Removed silc_server_command_join_notify as the function and its
5735 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Changed the client's pending command handling to the same as the
5738 server's pending command handling. It is also now possible to
5739 execute command reply functions from other command reply
5740 function as the function callbacks for commands and command
5741 replies are one and same. The pending commands are not static
5742 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5743 in client connection context. Thus, pending commands are server
5744 connection specific as it is convenient.
5746 Changed the function silc_client_command_pending and
5747 silc_client_command_pending_del and added new function
5748 silc_client_command_pending_check. Removed the
5749 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5752 * Added cmd_ident, current command identifier, to the client
5753 connection context in lib/silcclient/client.h to keep track on
5754 command identifiers used in command sending. Client's command reply
5755 function handling now supports the mandatory command identifiers.
5757 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5758 funtions in client to fully support pending command callbacks.
5760 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5761 as one of the arguments to the application in the command reply
5764 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5765 before first releasing SILC but came back. Now it is removed again
5766 and should come back nomore. The FORWARDED flag was used only
5767 by the JOINing procedure by forwarding the command packet to router.
5768 Now, the JOINing procedure has been changed to more generic (due
5769 to various router environment issues) and FORWARDED is not needed
5770 anymore for anything. The protocol specification is yet to be
5773 Now, removed silc_server_packet_forward from server and the flag
5774 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5776 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Renamed NAMES command to USERS command. The NAMES was named that
5779 due to historical reasons. Now it is renamed. Also, rewrote
5780 parts of the USERS command. The nickname list is not sent anymore
5781 by the server. Only Client ID and mode lists are sent in the USERS
5782 command. Changed this also to the protocol specification.
5784 The client now resolves the names and stuff after it receives
5785 the USERS list from the server when joining to the channel.
5787 * WHOIS and IDENTIFY commands has been changed to support multiple
5788 Client ID's per command. One can now search for multiple users
5789 in the network by sending only one WHOIS or IDENTIFY command.
5790 Changed the code and the protocol specifications.
5792 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5793 uses silc_server_command_whois_parse to parse the request. */
5795 * If normal server, do not parse the WHOIS and IDENTIFY requests
5796 before sending it to the router. Saves some time.
5798 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Fixed JOIN command on client library. Wrong number of arguments
5801 used to crash the client.
5803 * Added silc_server_channel_has_global function to check whether
5804 channel has global users or not.
5806 * Added silc_server_channel_has_local function to check whether channel
5807 has locally connected clients on the channel.
5809 * The silc_server_remove_from_one_channel now checks whether the
5810 channel has global users or not after given client was removed from
5811 the channel. It also checks whether the channel has local clients
5812 on the channel anymore. If it does not have then the channel entry
5813 is removed as it is not needed anymore.
5815 * The silc_server_notify now checks on JOIN notify whether the joining
5816 client is one of locally connected or global. If it is global then
5817 the channel has now global users on the channel and that is marked
5818 to the channel entry. Also, it now saves the global client to
5819 global list who is joining and JOINs it to the channel. This is
5820 for normal server, that is.
5822 Changed silc_server_send_notify_on_channel,
5823 silc_server_packet_relay_to_channel and
5824 silc_server_packet_send_to_channel check if we are normal server
5825 and client has router set (ie. global client) do not send the
5826 message to that client, as it is already routed to our router.
5828 * Implemented LEAVE notify type handling in silc_server_notify
5831 * Tested LEAVE command in router environment successfully. Tested
5832 with two routers, two servers and two clients.
5836 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5838 * Implemented SIGNOFF notify type handling in silc_server_notify
5841 * silc_server_remove_id now removes the client entry from all channels
5842 it has joined and thusly sends SIGNOFF notify type.
5844 * Rewrote the NAMES list generation in server by removing two excess
5845 loops. The lists are created now inside one loop.
5847 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * silc_server_remove_channel_user checks now also global list
5850 for channel and client.
5852 * silc_server_new_channel_user checks now both local and global
5853 list for channel and client. Fixed a bug in client id decoding.
5854 Used to decode wrong buffer.
5856 * silc_server_channel_message checks now both local and global
5857 list for channel entry.
5859 * Tested channel joining (hence JOIN) in router environment
5860 successfully. Tested with two routers, two servers and two
5863 * Tested channel message sending in router environment successfully.
5865 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Added silc_server_save_channel_key into server.[ch] to save the
5868 received channel key in Channel Key payload processing. It is
5869 also used in JOIN command reply handling.
5871 Equivalent function silc_client_save_channel_key added into
5872 client.[ch] into client library.
5874 * Changed JOIN command reply to send information whether the channel
5875 was created or not (is existing already) and the channel key
5876 payload. Changed protocol specs accordingly.
5878 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5879 the request was sent by ID and not by nickname. Crashed on
5882 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5885 now correctly save the received data.
5887 * silc_server_free_sock_user_data now notifies routers in the
5888 network about entities leaving the network.
5890 At the same time implemented functions silc_server_remove_id
5891 and silc_server_send_remove_id to receive and send REMOVE_ID
5892 packets. The packet is used to notify routers in the network
5893 about leaving entities. The ID removed will become invalid in
5896 * Added function silc_idlist_del_server into server. Removes and
5897 free's server entry from ID list.
5899 * silc_server_private_message function now checks, if we are router,
5900 that the destination ID really is valid ID, naturally.
5902 * In router when NEW_ID packet is received (for new client) the
5903 hash of the Client ID is saved in the ID Cache but the
5904 client->nickname is set to NULL, instead of putting the hash
5907 IDENTIFY command now also checks that client->nickname must be
5908 valid. If it is not if will request the data from the server who
5909 owns the client. Added new function
5910 silc_server_command_identify_check.
5912 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5913 to set the command to already allocated Command Payload.
5915 * Tested private message sending in router environment with two
5916 routers, two servers and two clients. Fixed minor bugs and now
5919 * Fixed segfault from client's NAMES command. Used to crash if
5922 * Forwarded packets must not be routed even if it is not destined
5923 to the receiver. Changed server code comply with this.
5925 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Added `require_reverse_mapping' boolean value to ServerParams
5928 structure. If TRUE (not default) the server will require that
5929 the connecting host has fully qualified domain name.
5931 If the reverse mapping is not required and hostname could not be
5932 found the IP address is used as hostname.
5934 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Implemented version string checking to both client and server.
5937 The check is incomplete currently due to the abnormal version
5938 strings used in development version of SILC.
5940 * Changed all command functions in server to use the new
5943 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Changed char *data to unsigned char *data in ID Cache system to
5946 support binary data as ID Cache data. Changed code to support
5947 binary data in lib/silccore/idcache.c.
5949 * Renamed silc_server_packet_relay_command_reply to
5950 silc_server_command_reply as it is normal packet receiving
5951 function. Rewrote the function to accept command replys for
5952 servers and not only for clients.
5954 * Mark remote router always as registered server if we are connecting
5955 to it. Otherwise, commands sent by the router to us are ignored.
5957 * All ID List find routines now returns the ID Cache Entry pointer
5958 as well if requested.
5960 * WHOIS command works now in router environment, tested with two
5961 routers, two servers and two clients.
5963 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5964 in router environment (as it is almost equivalent to WHOIS) but
5965 hasn't been tested thoroughly. Added new functions:
5967 silc_server_command_identify_parse
5968 silc_server_command_identify_send_reply
5969 silc_server_command_identify_from_client
5970 silc_server_command_identify_from_server
5972 * Disabled route cache adding because adding two different ID's with
5973 same IP replaces the old cache entry thus giving wrong route.
5974 The entry->router->connection is always the fastest route anyway
5975 so route cache may not be needed. Of course, new routes maybe
5976 established after receiving the ID when the entry->router->connection
5977 might not be anymore the most optimal.
5979 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Add route cache for received ID for fast routing.
5983 * Added silc_server_packet_route to route received packet on router
5984 that is not destined to us.
5986 * Renamed silc_server_get_route to silc_server_route_get.
5988 * Added id_string and id_string_len fields into SilcServer to
5989 include encoded ServerID for fast comparing without excess
5990 encoding of the ID's.
5992 * Cleaned up WHOIS command on server side. Added following static
5995 silc_server_command_whois_parse
5996 silc_server_command_whois_check
5997 silc_server_command_whois_send_reply
5998 silc_server_command_whois_from_client
5999 silc_server_command_whois_from_server
6001 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6002 arguments in command replies. All command functions should be
6003 updated to use this macro.
6005 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Minor typo fixes on command reply handling on server.
6009 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6011 * Added silc_server_command_add_to_channel internal routine to add
6012 the client to the channel after router has created the channel and
6013 sent command reply to the server.
6015 * Added generic silc_server_send_command to send any command from
6018 * Use static buffer with ID rendering instead of duplicating data.
6020 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Fixed a channel user mode bug when joining to a channel server gave
6023 everybody channel founder rights, oops.
6025 * We mark ourselves as the router of the incoming server connection
6026 if we are router ourselves. This way we can check in some packet
6027 sending functions whether it is locally connected server. For
6028 incoming router connections we put NULL.
6030 * For router sending packets locally means now always sending the
6031 packet cell wide; to local clients and local servers. For normal
6032 server sending packet locally means sending it to only local
6035 * Fixed the JOIN command to really work in router environment. If the
6036 channel is created it is always created by the router. Router is
6037 also responsible of making the initial joining to the channel,
6038 sending JOIN notify to the sending server and distributing
6039 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6040 does not exist server doesn't do anything else but forward the
6041 command to the router which performs everything.
6043 * Added silc_server_send_channel_key function to send the Channel Key
6046 * Added silc_server_create_channel_key to create new channel key. The
6047 channel key is now re-generated everytime someone joins or leaves
6048 a channel, as protocol dictates. Note: channel->key_len is the
6051 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6054 packet_receive.[ch] to separate packet sending and receiving
6055 routines. The server.[ch] now includes everything else including
6056 actual packet processing (writing and reading data) and other
6059 Renamed silc_server_private_message_send_internal to
6060 silc_server_send_private_message. The routine is still though
6061 used only to relay private messages as server does not send
6062 private messages itself.
6064 Renamed silc_server_new_channel to silc_server_create_new_channel
6065 and added new function sicl_server_new_channel that handles the
6066 incoming New Channel packet. Added also new sending function
6067 silc_server_send_new_channel to send New Channel Payload.
6069 * Added new function silc_server_notify to process incoming notify
6070 packet to the server/router. Server may then relay the notify
6071 to clients if needed.
6073 * Added new function silc_server_new_channel_user to process incoming
6074 New Channel User packet. Router will redistribute the packet and
6075 send JOIN notify to its local clients and locally connected servers
6076 if needed. Normal server will send JOIN notify to its local client
6077 on same channel when received this packet. Added also corresponding
6078 sending function silc_server_send_new_channel_user to sent the
6081 * Added boolean route argument to send_notif_to_channel and
6082 packet_send_to_channel functions to attempt to route the packet
6083 if it is TRUE and send only locally if it is FALSE.
6085 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * silc_server_replace_id now broadcasts the received replace ID
6088 packet if it is not broadcast packet already. The router must
6089 broadcast to inform other routers about changed ID.
6091 * Added backpointer to server's router into SilcServer context in
6092 silcd/server_internal.h.
6094 * Fixed silc_server_packet_broadcast to send correct broadcast
6097 * The channel key is now distributed to the local client as soon
6098 as it is received from the router (in router environment) so that
6099 no other packet may be sent for the channel until client has
6102 * silc_server_remove_channel_user now broadcasts the received
6103 Remove Channel User packet if it is not broadcast packet already.
6104 The router must broadcast to inform other routers about removed
6107 * Added users field into SilcPacketContext that is a reference count
6108 of the context. One can increase the reference count by calling
6109 silc_packet_context_dup which is now changed to just increase the
6110 reference count instead of duplicating the data. The reference
6111 count is decresed by calling silc_packet_context_free that will
6112 free the data after the reference count hits zero.
6114 For now on the packet context and everything allocated into it
6115 (including the raw packet from network) must be freed by calling
6116 the new silc_packet_context_free function. Added also new function
6117 silc_packet_context_alloc that must be used now to allocate the
6118 context. This also means that if a routine is asynchronous from
6119 silc_[client/server]_packet_parse_type the packet context must
6120 be duplicated by calling silc_packet_context_dup. Otherwise it
6121 gets free'd after silc_[client/server]_packet_parse_type returns.
6122 Also, one must remember that if packet is duplicated then its
6123 reference count must be decresed by calling the free function as
6124 many times as it was duplicated.
6126 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6127 from both client and server.
6129 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Made joining to a channel working in router environment.
6133 * Cleaned up JOIN command on server side and create function
6134 silc_server_command_join_channel internal routine to make the
6137 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Changed silc_command_pending list to SilcDList. Also, added
6140 `ident' field to SilcServerCommandPending structure to identify
6141 the reply and to call correct callback.
6143 Added silc_server_command_pending_check function to replace the
6144 corresnponding macro. The silc_command_pending list is not
6147 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6148 to set identifier to previously allocated Command Payload. It
6149 is used to set identifier for command when resending Command
6152 * Added silc_command_payload_encode_payload to encode Command
6153 Payload buffer from SilcCommandPayload structure.
6155 * Added silc_argument_payload_encode_payload to encode Argument
6156 payload buffer from SilcArgumentPayload structure.
6158 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Changed WHOIS command to support router connection on server side.
6161 The whois request is always sent to router unless the server is
6162 standalone server. After server has received the reply from the
6163 router will it send the reply to the client.
6165 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6166 broadcast received broadcast packet. The function is used only
6167 by router. The broadcast packet is always sent to the router's
6170 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6171 render given ID to printable string, for log files for example.
6173 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Made basic router to router connections working. At least they
6176 can now connect to each other but nothing really works the way
6177 they are supposed - yet.
6179 * Added new initiator token to RouterConnection configuration
6180 file in silcd/serverconfig.[ch]. It is used to tell whether we
6181 are the initiator to the remote router or whether we'll expect
6182 the other end to connect.
6184 * Moved registering of listener task to silc_server_init, hence
6185 the server starts listenning as soon as it is run, even if it
6186 does not have connections to other routers. Let's see how well
6189 * Changed default connection retry timeouts for more suitable in
6192 * Removed cipher and such arguments from silc_idlist_add_client
6193 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6194 Added new function silc_idlist_add_data to add the keys and stuff
6197 * Added SilcIDListData structure and added it to SilcClientEntry
6198 and SilcServerEntry as their first field in the structure. This
6199 way we can explicitly cast the ID entries to the SilcIDListData
6200 structure and get common data for the entries. In past, we had
6201 to first check what type of connection it is and then cast it to
6202 correct ID entry type. Now, we can directly cast the opaque
6203 pointer to the SilcIDListData (no matter what ID entry it actually
6204 is) and get the data needed.
6206 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6209 in some circumstances even if threre were timeout tasks, though not
6210 IO tasks, but tasks anyway. Now fixed.
6212 * Defined SilcServerConnection structure to hold connection specific
6213 stuff about directly connected servers and routers. The definition
6214 is currently in silcd/server_internal.h. I thought about having
6215 a bit more important role fro this struct but for now it is used
6216 only when connecting to other server (or router actually).
6218 * Added connecting retry support in server when connecting to
6219 router(s). The retry feature implement exponential backoff
6220 algorithm. Also, added SilcServerParams structure to hold default
6221 parameters for server. For now, it include these retry settings
6222 and are hard coded. After server is moded to be as Silc Server
6223 Library this structure will be more important.
6225 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Changed client librarys channel->clients table to SilcList and
6228 changed code accordingly.
6230 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Changed client's channel table to SilcList and changed code
6233 accordingly. Also changed SilcChannelClientEntry to include back-
6234 pointer to the channel so that client entry can use that structure
6235 as list as well and we have fast cross-reference to the channel.
6236 This change dramatically decreased the complexity of channel
6237 handling with client entry and vice versa (removed one extra
6238 loop when searching for channel entry from many functions).
6240 * Changed server->sim from table to SilcDList and changed code
6243 * NAMES command can now be used from user interface. It will show
6244 the user list on the channel, neatly.
6246 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6247 Code now saves realname of the user if it becomes available.
6249 * Renamed configure.in to configure.in.pre and made ./prepare
6250 script to automatically add correct version string to
6251 configure.in which it creates from configure.in.pre.
6253 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * NAMES command reply now shows users mode with the nickname when
6258 * Moved silc_client_ch[u]mode[_char] functions from
6259 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6260 place sucks, they are utility functions and should be in some
6263 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6265 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6268 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Added TRQ (efficient deque and list library) into lib/trq. This is
6273 a very good list library that is currently used in the SILC. Defined
6274 SilcList API over the library because I didn't like the API very
6275 much. See lib/trq/silclist.h for the API and examples of how to
6276 use the API. Fixed various places in the code to use the new
6277 SilcList API. The SilcList is meant for lists that has a structure
6278 already defined as a list. It is not suitable to add just some
6279 context to the list (in TRQ, the context is the list actually).
6281 So, I defined SilcDList that can be used for the purpose where
6282 predefined list structure does not exit. This can be used as
6283 such list. Now some context just can be added to the SilcDList.
6284 Currently this list is not used in the SILC just yet, though there
6285 are a lot places where this can replace dynamically allocated
6286 tables and I will fix these places, later, to use SilcDList.
6287 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6288 and use TRQ internally).
6290 Also fixed some annoying warning messages that the original TRQ
6291 code generated. Also minor changes to TRQ's Makefile.in.
6293 * Added support for querying by Client ID to both WHOIS and
6294 IDENTIFY commands into server, as required by the protocol.
6296 * Removed method function pointers from SilcBuffer structure. They
6297 weren't used to anything and just increased the context size for
6298 no good reason. This change also made silc_buffer_alloc and
6299 silc_buffer_free functions inline functions.
6301 * Disabled command flooding detection support until it's fixed so
6302 that it accepts commands in but does not execute them more than once
6305 * Added silc_net_localhost(), to return local hostname, into
6306 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6307 that must be initialized before calling silc_client_init.
6309 * Added new function: silc_server_send_notify_on_channels to send
6310 notify messages to all channels client has joined. It is assured
6311 that the message is sent only once per client.
6313 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6314 lib/silcutil/silcutil.[ch] as silc_format function. The new
6315 function is generic and is used by server as well, not only by
6316 the logging routines.
6318 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6319 the provided version string was not acceptable. Added new function:
6320 silc_ske_check_version into lib/silcske/silcske.h. The function
6321 must be implemented by the application (client or server) and it
6322 does not reside in the SKE library. The function checks the version
6323 string remote end sent.
6325 * Added back pointers (to opaque context and to SilcSocketConnection)
6326 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6328 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6329 duplicate packet context structure.
6331 * Changed `notify' client operation to send same arguments as client
6332 receives from server except for ID's. ID's are mapped to correct
6333 ID entry and that is returned. Also, if channel entry is not sent
6334 by server but the notify is for channel the channel entry is sent
6335 to application (otherwise application doesn't know that it is for
6336 channel (library gets it from packet's Destination ID)).
6338 * Added silc_client_remove_from_channels into client library to
6339 remove a client from all channels it has joined to. Used when
6340 received SIGNOFF notify from server. Added also new function
6341 silc_client_replace_from_channels to replace old ID entry with
6342 new ID entry on all channels. Used when received NICK_CHANGE
6345 * Fixed ID Cache list handling in silc_idlist_get_client in
6346 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6347 to get (or query) client by ID.
6349 * Updated TODO list.
6351 * Added connection authentication status message defined by the
6352 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6353 support for these into the code in client and server side.
6355 * Added generic function silc_client_send_command to send any command
6356 with variable argument list. Application should use this function
6357 to send commands if the command functions provided by the library
6358 does not suite for the application's user interface needs.
6360 * Added new `failure' client operation. Application is notified about
6361 received failure packet if client is executing a protocol. In this
6362 case the protocol's execution has failed.
6364 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6365 is required by the protocol.
6367 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6368 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6371 * Added status flag to SilcSKE object to indicate realtime status
6372 of the SKE protocol.
6374 * Application receives now exactly same command reply arguments as
6375 the library receives from server. However, if ID is received the
6376 corresponding ID entry is returned to the application (eg. Client
6377 ID is mapped to correct SilcClientEntry entry and that is returned).
6378 Changed command_reply client operation due to this change.
6380 * Changed all ID's in commands and in command replys as ID Payloads.
6381 Change affected both client and server side codes.
6383 All ID's sent in SILC network (with execption of ID's in SILC
6384 Packet header) are sent in ID Payload to support variable length
6387 * Server now notifies nick changes and notifies all clients on
6388 the channels about the new nickname (about the new Client ID,
6391 * Implemented CMODE command to change channel modes. Supports all
6392 channel modes defined by the protocol specs except ban and invite
6393 lists. (Also, private channel key mode is supported but support for
6394 setting private channel key in client is missing, thus, this mode
6395 has no effect on client side (except that server requires that the
6396 client uses private channel key and normal channel traffic does not
6399 Also, invite mode works per se, but INVITE command does not work
6400 yet correctly, so you can set channel as invite only channel but
6401 inviting clients to the channel does not work (it is yet to be
6402 thought what's the best way to do it).
6404 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6405 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6406 Implemented CUMODE command to change user's mode on the channel.
6407 Supports all modes defined by the protocol specs.
6409 * Added NAMES command reply to return users modes on the channel.
6411 * Removed unnecessary and slow ciphers from lib/silccrypt.
6413 * Set SO_KEEPALIVE option to connection sockets by default.
6415 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6417 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6418 redefined the Notify Payload into protocol specs.
6420 * Added silc_id_payload_parse_id to get ID directly from raw
6423 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6426 accept searching by Client ID as well.
6428 * Added support for LEAVE and SIGNOFF notify types in client library.
6430 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6431 to parse ID Payload from raw data.
6433 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Added flags parameter into silc_ske_assemble_security_properties
6436 function in lib/silcske/silcske.[ch].
6438 * Changed notify client operation to fit better for notify messages
6439 sent by server. The notify payload received from server is now
6440 passed to the application (after parsing it to SilcNotifyPayload).
6441 It is application's responsibility to retrieve the arguments
6442 from the payload and show the message the way it wants. The message
6443 sent by server is implementation specific.
6445 * Changed public keys to comply with the protocol specification.
6446 Old public keys are not supported anymore and are not compatible.
6448 * Removed nickname from Channel Payload as the latest draft removed
6449 it. The client must resolve the nickname from the NAMES command
6450 reply received when it joined the channel.
6452 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6454 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Fixed some errors in protocol specification drafts.
6458 * Created lib/silccore/silcnotify.c to implement Notify Payload
6459 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6460 generic payloads described by protocol specifications. The file
6461 includes implementations for ID Payload and Argument Payload.
6463 * Changed Command Payload implementation to use the new Argument
6464 Payload. Changed command_xxxx_payload to command_payload_xxxx
6465 to comply with SILC coding conventions.
6467 * Added suppport for Argument Payload handling in Notify Payload
6468 implementation as protocol requires it. Added the new support
6469 into server and client lib as well.
6471 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Added support for multiple nicknames on same channel. [n] is
6474 added locally to the nickname if there are more than one same
6475 nicknames on the channel.
6477 * Server now sends all nicknames that matched WHOIS request.
6478 Client also shows the list received from server.
6480 * Added TOPIC command to client side. User can now set and show
6481 current topic on channel.
6483 * Added MOTD command to client and server. Also, server sends the
6484 motd when client connects to the server.
6486 * Changed version strings to comply ISO 8601.
6488 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Fixed protocol error handling in client library. It should now
6491 cope even if the SKE fails for some reason.
6493 * Made new protocol specification drafts for submitting to IETF.
6495 * Implemented TOPIC command to server in silcd/command.c.
6497 * Added two new notify types into lib/silccore/silcnotify.h:
6498 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6499 notify nickname change and topic setting/change on a channel.
6501 * API change of command_reply operation in client library. The
6502 application gets now the status type received from server as well.
6504 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6508 * Cras fixed and optimized the packet handling even further and
6509 it should work now. Minor change to the prototype of function
6510 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6512 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Added new function into lib/silcutil/silcschedule.[ch]:
6515 silc_schedule_with_fd to select() a specified fd. The function
6516 returns after timeout expires or data arrives or goes. The
6517 function is used by packet routines to wait that all data is
6518 received from network.
6520 * Fixed data reading from network in lib/silccore/silcpacket.c.
6521 The code now assures that all data is read from the fd and then
6522 continues packet processing. This was a bug fix since the code
6523 used to drop some data in some circumstances.
6525 * Added new function into lib/silcclient/client.[ch]:
6526 silc_client_start_key_exchange to start key exchange after
6527 connection has been established to server. The code internally
6528 now uses this funtion but its main purpose was to provide it
6529 for applications that perform their own connecting. After
6530 application has created a connection it merely calls this
6531 function to start the key exchange between client and server.
6532 The library takes care of everything else after that.
6534 Updated also lib/silcclient/README to explain the usage of
6537 * Do not send to application information that connection has
6538 been established. Application gets notified it by connect
6541 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Applied cras's patch to add silc_schedule_one function. The
6544 function runs scheduler once and returns.
6546 * Fixed the scheduler after cras messed it up. The timeout
6547 handling works now as it's supposed to work.
6549 * Added into lib/silccore/ silcnotify.h to include notify
6550 message types support. Changed silc_server_send_notify*
6551 functions, in server.[ch], to support those new notify types.
6552 Added the support for the notify types into client library,
6553 as well. Added new notify client operation into ops.h in
6556 * Changed silc_server_packet_send_to_channel to send normal
6557 packets instead of just channel message packets. The function
6558 is now used to send the notify packets to channels. It is not
6559 used to send channel message packets anymore, as server never
6562 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6563 va_arg()s as it seems to require it nowadays. I guess, if SILC
6564 is compiled with older va_arg() the new code should work anyway.
6566 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Splitted core library. Core library (lib/silccore) includes
6569 now only SILC protocol specific core (and common) components.
6570 Created new utility library (lib/silcutil) that includes more
6571 generic purpose stuff. The stuff for util library was taken
6572 from the old core library. This was minor and easy split.
6574 * Created SILC Client Library (lib/silcclient) that includes
6575 implementation of the SILC client without user interface. This
6576 was major move from silc/ directory. The code has been changed
6577 so that it is transparent towards the user interface. The
6578 silc/ directory includes now the same user interface as before
6579 and it uses the new client library. Read lib/silcclient/README.
6580 Basicly, the client library performs everything else related
6581 to SILC except user interface handling. Also, configuration
6582 files are considered to be part of user interface and library
6583 does not handle them.
6585 This change also changed a lot of structures, function naming etc.
6586 Most important change was that SilcClientWindow object was
6587 renamed to SilcClientConnection in the client library. Created
6588 also new file lib/silcclient/ops.h. Also added new files
6589 silc/local_command.[ch] and silc/client_ops.[ch].
6591 All these changes were made to make it easier for user interface
6592 designers to create what ever user interface for the SILC client
6595 It is also expected that the server will be moved to lib
6596 directory as well and SILC Server Library will be created;
6597 sometimes in the future.
6599 * Removed Local commands from lib/silccore/silccommand.h as
6600 they are application specific and new client library does not
6601 handle any of those anymore.
6603 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6604 old client implementation in silc/.
6606 * Added support for callback functions in SILC_LOG_* macros.
6607 Application can now set its own callbacks that will be called
6608 instead of using the default functions that will always print
6609 the debug messages to stderr (or stdout). Also, debugging can
6610 now be disabled by setting silc_debug to FALSE and re-enabled by
6611 setting it to TRUE. Note, that logging will still work even
6612 if debugging is disabled.
6614 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6615 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6616 silc_log_reset_debug_callbacks.
6618 * To enable debugging in silc client one must give now -d
6619 option on command line.
6621 * Changed silc_schedule_init to automatically allocate task queues
6622 if they are not allocated before calling it.
6624 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Added GMP 3.1 into math library.
6628 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6631 a channel in SILC network. The packet is used by servers and
6632 routers to notify other routers that user has left a channel.
6633 This little feature was missing until now. Added the feature
6634 to protocol specification as well.
6636 Added functions: silc_server_send_remove_channel_user and
6637 silc_server_remove_channel_user into server.[ch].
6639 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6640 lib/silccore/silcpacket.h. However, they are not implemented
6643 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * Fixed joining to a channel and sending channel messages
6646 between server and router. The channel message sending should
6647 now work inside a cell.
6649 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Fixed the private message sending between server and router.
6652 The private message sending should now work inside a cell.
6654 * Added silc_server_replace_id into server.[ch] to replace
6655 existing ID in the SILC network.
6657 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6658 and silc_idlist_replace_server_id into idlist.[ch] in server.
6660 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Fixed the server to server connections. Server can again now
6663 connect to router. Router to router connections probably does
6666 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Added dynamic protocol registering support. Now protocols can
6669 registered and unregistered on the fly. Patch by cras.
6671 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Added lib/contrib directory to hold routines that some platforms
6674 don't have but are needed by SILC.
6676 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6677 into lin/contrib to provide getopt() and getopt_long() for
6678 those who don't have it.
6680 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6682 * Added AWAY command to client. When away message is set and
6683 client receives a private message packet the client automatically
6684 replies to the sender with the away message.
6686 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6687 bug seemed to be the cause of recent problems when compiling
6690 * Added version detection support to SKE protocol specification
6691 and added the new changes to the SKE implementation as well.
6692 There were other minor changes in the SKE protocol as well.
6694 Many changes in lib/silcske/silcske.[ch] and in
6695 lib/silcske/payload.[ch].
6697 * Added ^U functionality, clear input line. Patch from cras.
6699 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Mainly small bugfixes on core library. Fixed some debugging
6702 logging and buffer overflow in silclog.c.
6704 * Updated config.sub and config.guess on the distribution tree.
6706 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6708 * Added command lagging support in server. Client may execute
6709 commands now only once in two seconds.
6711 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Optimized packet reception. MAC computation and checking is now
6714 also more optimized. A lot previously duplicated code is now
6715 used as generic by both client and server.
6717 * Fixed key pair generation in clientutil.c
6719 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Added into lib/silccore/silcbufutil.[ch] new function;
6722 silc_buffer_realloc.
6724 * Moved generic packet sending/encryption functions to
6725 lib/silccore/silcpacket.[ch] from client and server. Some
6726 rewriting of the functions.
6728 * Moved all generic packet reception/decryption functions to
6729 lib/silccore/silcpacket.[ch] from client and server. The
6730 packet processing is now much cleaner in both client and server.
6731 These were major changes in both client and server.
6733 * Created many common functions in server to do packet sending.
6734 Previously code were duplicated a lot, this has been removed
6737 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Rewrote major parts of the ID cache system. Don't know
6740 whether it is better now or not but at least the API is more
6743 * Major rewrite on ID cache stuff on client because of the ID
6744 cache API changes. Added idlist.c to client.
6746 * Also major rewrite on ID cache stuff on server as well.
6747 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6748 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6749 in hand, instead they are all put into the ID cache system now.
6750 All server_idlist_* routines uses ID cache now instead of
6751 traversing its own lists (those lists does not exist anymore).
6752 SilcIDList though still exists. Also, SilcXXXEntry's are
6755 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Finally made the SKE implementation compliant to the protocol
6758 specification. All mp integers are now binary encoded as
6759 opposed being HEX encoded.
6761 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6764 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6765 functions: silc_[encode/decode]_pem. Also added function
6766 silc_encode_pem_file to PEM encode with newlines ('\n') for
6769 * SILC public keys are now encoded either PEM or binary. Same
6770 option is for private keys as well. By default private keys
6771 are binary encoded and public keys PEM encoded. Silly HEX
6772 encoding were removed.
6774 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6775 function to create fingerprints.
6777 * Fixed a bug in SHA1; does not change the original data anymore.
6779 * Partly implemented INFO command on client and server side.
6780 Fixed CLEAR command. Changes to SERVER command; show current
6781 server(s) when giving command without arguments. Added
6782 VERSION command to client.
6784 * Added check to server that unregistered connections cannot
6785 execute commands (unless it is specificly allowed).
6787 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed screen refresh.
6791 * Fixed channel joining bug from client. On some circumstances
6792 client tried to join to a channel it had already joined.
6794 * Added public key verification process into client's protocol.c.
6795 The client now verifies the public key from user and saves
6796 it into ~./silc/serverkeys/ directory.
6798 Added into: clientutil.[ch]: silc_client_verify_server_key.
6800 * Changed SKE protocol's silc_ske_initiator_finish function
6801 to accept callback function that verifies the received public
6802 key. Removed old silc_ske_verify_public_key function.
6804 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6806 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6807 silc_pkcs_private_key[_data]_set.
6809 * Made the password and public authentication more cleaner in
6810 server's protocol.c.
6812 * Removed historic and obsolete protocol `channel_auth' from
6813 both client and server.
6815 * Removed wrong way of sending command status messages from
6816 server to client in server's command.c. The old way violated
6817 protocol specification.
6819 Changes to silccore/silccommand.[ch]: removed
6820 silc_command_encode_status_payload -> not needed anymore,
6821 changed silc_command_encode_payload_va to accept extra
6822 argument on variable argument list. The argument type must
6823 now be provided to the function. Also, added new function:
6824 silc_command_encode_reply_payload_va which is same as
6825 normal command_encode_payload_va except command status type
6826 is provided as extra argument.
6828 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Added ~./silc directory handling. The directory includes the
6831 public and private keys for the client.
6833 Added silc_client_check_silc_dir, silc_client_create_identifier
6834 and silc_client_load_keys.
6836 * Implemented SILC protocol compliant public key. Added public
6837 and private key saving to and loading from files.
6839 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6840 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6841 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6842 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6843 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6845 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6846 silc_pkcs_load_[public/private]_key.
6848 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Added silc_server_get_route (route.[ch]) to get connection
6851 data for the fastest route for given ID.
6853 * Implemented INVITE command on client and server. The command
6854 were re-defined in the SILC Protocol Specification and the
6855 implementation now complies with the specification.
6857 * Implemented PING command on client and server.
6859 * Implemented NAMES command on client and server. The server side
6860 supports currently only normal server not router server yet.
6861 Some changes to NAMES definition in SILC protocol specification.
6863 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Implemented LEAVE command on client and server.
6867 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6868 again. This change was made to the protocol as well. Server
6869 should not violate the protocol specification anymore.
6871 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6873 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6874 was tested. SOCKS4 was not but should work anyway.
