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

566 and a little WHOIS problem.
568 * Fixed silc_net_gethostbyname to correctly call the
569 inet_ntop. Affected file lib/silcutil/silcnet.c.
571 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
573 * Added IPv6 support checking to the configure.in.pre, added
574 also --enable-ipv6 option to override the check. Affected
575 file configure.in.pre.

608 UI displays it. Affected files lib/silcclient/client_notify.c
609 and irssi/src/silc/core/silc-channels.c, module-formats.c.
611 * Made all payload parsing function prototypes consistent.
612 They all take now const unsigned char * and uint32 pair as
613 the payload data instead of SilcBuffer. Changes all around
614 the source tree. Other unsigned char* -> const unsigned char*
615 changes around the tree as well.
617 * Optimized SFTP client and server packet sending not to
618 allocate new buffer for each packet but to recycle the
619 first allocated buffer. Affected files are
620 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
622 * Optimized the SFTP client to use SilcList instead of
623 SilcDList for requests, because it is faster. Affected file
624 is lib/silcsftp/sftp_client.c.
626 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
627 into lib/silccore/silcid.[ch].

631 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
633 * If client entry is deleted with active key agreement
634 session, abort the session.
636 The silc_client_abort_key_agreement now calls the completion
637 callback with new SILC_KEY_AGREEMENT_ABORTED status.
639 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
642 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Don't use __restrict in older GCC's. Affected file is
645 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
647 * silc_net_localhost now attempts to reverse lookup the
648 IP/hostname. Affected file lib/silcutil/silcnet.c.
650 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
651 command. It can be used to gain founder privileges at
652 the same time when joining the channel.
654 Defined that the SILC_NOTIFY_TYPE_KICKED send the
655 kicker's client ID as well. Updated protocol specs.
657 Defined that the server must send SILC_COMMAND_IDENTIFY
658 command reply with error status to client who sent
659 private message with invalid client ID.
661 Updated the protocol specification.
663 * Added silc_server_send_command_reply to send any
664 command reply. Affected file silcd/packet_send.[ch].
666 * Added silc_id_payload_encode_data to encode ID payload
667 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
669 * The server now send IDENTIFY command reply with error
670 status if client ID in private message is invalid. Affected
671 file silcd/packet_receive.c.
673 * Save the server key file with server's IP address in
674 the filename instead of hostname. The affected file is
675 irssi/src/silc/core/client_ops.c.
677 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
679 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
682 * Added libtool support for compiling shared objects in
683 lib/silcsim. Affected file configure.in.pre and
684 lib/silcsim/Makefile.am. Original patch by cras.
686 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
688 * Pid file configuration, and server's config file fixes
689 patch by toma. Updated CREDITS file.
691 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
693 * Fixed silc_client_channel_message to not try to decrypt
694 the message twice if it resolved the destination client
695 information. This could cause of dropping one channel
696 message. Affected file lib/silcclient/client_channel.c.
698 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Added silc_client_run_one into lib/silcclient/silcapi.h and
701 lib/silcclient/client.c. This function is used when the SILC
702 Client is run under some other scheduler, or event loop or
703 main loop. On GUI applications, for example this may be
704 desired to used to run the client under the GUI application's
705 main loop. Typically the GUI application would register an
706 idle task that calls this function multiple times in a second
707 to quickly process the SILC specific data.
709 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
711 * Fixed silc_server_drop() for dropping the supplementary
712 groups as well, this could cause a security hole on some
715 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
717 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

721 to run server on foreground. A patch by debolaz.
722 Affected files silcd/server.c, silcd/silcd.c.
724 * Fixed MOTD to return the MOTD file server name. Affected
725 file silcd/command.c.
727 * Added INFO command reply handling to the Irssi SILC Client.
728 Affected file irssi/src/silc/core/client_ops.c.
730 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
732 * Fixed the silc_idcache_list_* routines to really support
733 the dynamic list. Fixes a crash. Affected file is
734 lib/silccore/silcidcache.c.
736 * Fixed the LIST command reply to really call LIST command's
737 pending callbacks. Affected file silcd/command_reply.c.
739 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
741 * Update conn->local_entry->nickname after giving NICK
742 command. Affected file lib/silcclient/command.c.
744 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
746 * Added the [pid] option to the silcd configuration file
748 Affected files: serverconfig.[ch] and silcd.c

752 * Save fingerprint in WHOIS command reply in server.
753 Affected file silcd/command_reply.c.
755 * Fixed NICK commands pending callback registration.
756 Affected file lib/silcclient/command.c.
758 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
760 * Use ++server->cmd_ident when sending commands in server,
761 instead of random number. Affected file silcd/command.c.
763 * Fixed GETKEY command reply to call actually GETKEY pending
764 command callbacks. Affected file silcd/command_reply.c.
766 * A bit stricter check for nicknames. Check for same nickname
767 in NICK command also. Affected file silcd/command.c.
769 * Do not call INFO command everytime client ID changes, only
770 during first connecting. Affected file lib/silcclient/client.c.
772 * Set the new nickname only after successful command reply for
773 NICK command is returned by server. Affected file
774 lib/silcclient/command.c.
776 * Remove nicknames from nicklist during server_signoff notify.
777 Should fix /NAMES bit more. The affected file is
778 irssi/src/silc/core/silc-channels.c.
780 * Added `fingerprint' field to the SilcIDListData in the
781 silcd/idlist.h to hold the fingerprint of the client's
784 Send the fingerprint of the client's public key in WHOIS
787 Affected files silcd/command.c, and silcd/idlist.[ch].
789 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
790 create fingerprint from given data.
792 * Show the fingerprint of the client's public key in WHOIS.
793 Affected files irssi/src/module-formats.[ch] and
794 irssi/src/silc/core/client_ops.c.
796 * Format the multiple same nicknames also during JOIN and
797 NICK_CHANGE notifys. Affected file is
798 lib/silcclient/client_notify.c.
800 * Do not print error on screen for invalid private message
801 payload since it can come if someone is sending private
802 messages with wrong key. Affected file
803 lib/silccore/silcprivate.c.
805 * Fixed multiple concurrent /PING crash. Affected file
806 lib/silcclient/command.c.
808 * Changed the wrong ID encoding. All IP addresses must be
809 in MSB first order in encoded format. They were encoded
810 wrong and was in LSB format. Affected files are
811 silcd/serverid.c, lib/silcutil/silcutil.c.
813 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
815 * Call the `connect' client operation through the scheduler
816 in case of error. Affected file lib/silcclient/client.c.
818 * Call the `failure' client operation even if the error
819 occurred locally during a protocol. Affected file is
820 lib/silcclient/protocol.c.
822 * Added support of sending LIST command to router from normal
823 server. This way normal server can get list of all channels
824 in the network too. Fixed the channel list sending in the
825 server too. Affected files are silcd/command.c, and
826 silcd/command_reply.[ch].
828 * Added silc_server_update_channels_by_server and
829 silc_server_remove_channels_by_server. They are used during
830 disconnection of primary router and in backup router protocol.
831 Affected file silcd/server_util.[ch], silcd/server.c and
832 silcd/server_backup.c.
834 * Fixed channel adding to global list in IDENTIFY command
835 reply in server. Affected file silcd/command_reply.c.
837 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
839 * If the incoming packet type is REKEY or REKEY_DONE process
840 that packet always synchronously. Fixes yet another MAC
841 failed error on slow (dialup) connections. Affected file
842 lib/silcclient/client.c and silcd/server.c.
844 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
846 * Call check_version SKE callback for initiator too. Affected
847 file lib/silcske/silcske.c.
849 * Implemented fix for security hole found in the SKE that was
850 fixed in the specification few days back; the initiator's
851 public key is now added to the HASH value computation.
852 Added backwards support for the old way of doing it too, for
853 old clients and old servers. Affected file is
854 lib/silcske/silcske.c.
856 * Enabled mutual authentication by default in SKE. If initiator
857 is not providing mutual authentication the responder will
858 force it. This will provide the proof of posession of the
859 private key for responder. The affected files are
860 lib/silcclient/protocol.c and silcd/protocol.c.
862 * Do not cache anymore the server's public key during SKE.
863 We do mutual authentication so the proof of posession of
864 private key is done, and if the server is authenticated in
865 conn auth protocol with public key we must have the public
866 key already. Affected file silcd/protocol.c.
868 * Added new global debug variable: silc_debug_hexdump. If
869 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
870 file lib/silcutil/silclog.[ch].
872 * Fixed compilation warning due to char * -> const char *.
873 Affected files lib/silcutil/silcnet.h, and
874 lib/silccore/silcauth.[ch].
876 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
878 * Fixed CMODE command when new channel key was created. If
879 the creation failed the old key was removed. Next time giving
880 same command would crash the server since the old key was
881 freed already. Affected file silcd/command.c.
883 * Fixed the silc_server_announce_get_channels to not crash
884 on reconnect. Affected file silcd/server.c.
886 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Added silc_log_set_debug_string function to set a regex
889 string to match for debug output. Only the function names,
890 or filenames matching the given debug string is actually
891 printed. This way it is possible to filter out those debug
892 strings that user is not interested in.
894 Fixed a bug in silc_string_regexify.
896 Affected files lib/silcutil/silclog.[ch], and
897 lib/silcutil/unix/silcunixutil.c.
899 * Changed the -d options in both server and Irssi SILC client
900 to take the debug string as argument. Affected files
901 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
903 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
905 * Added silc_hash_babbleprint to create a Bubble Babble
906 Encoded fingerprint. The encoding is developed by Antti
907 Huima (draft-huima-babble-01.txt), and it creates human
908 readable strings out of binary data. Affected file
909 lib/silccrypt/silchash.[ch].
911 * Print the babble print now in addition of fingerprint as well
912 in Irssi SILC client. Affected files are
913 irssi/src/fe-common/silc/module-formats.[ch],
914 irssi/src/fe-common/silc/core/client_ops.c.
916 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Fixed a security problem found in SKE. The initiator's
919 public key too is now added to the HASH hash value creation
920 which is signed by the responder to create the SIGN value.
921 This will prevent anyone in the middle to lie to the responder
922 about the initiator's public key. If this is done now, the
923 man in the middle will get caught. Updated the protocol
926 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Better installation directory handling. Configure module
929 paths and other paths automatically to example_silc* files
930 in doc/. A patch by toma.
932 * Fixed compiler warning from MPI library, and from SILC RNG.
935 * Added SILC_SERVER_PID_FILE to define the pid file for server.
936 It can be configured with ./configure. A patch by toma.
938 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Find correct make to use in prepare-clean. A patch by
941 toma. Affected file prepare-clean.
943 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
945 * Added irssi variables use_auto_addr, auto_bind_ip,
946 auto_bind_port and auto_public_ip.
948 * Changed the interface for silc_client_send_key_agreement
949 in lib/silcclient/silcapi.h
953 irssi/src/silc/core/silc-core.c
955 lib/silcclient/silcapi.h
956 irssi/src/silc/core/silc-channels.c
957 lib/silcclient/client_keyagr.c
960 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Added silc_pkcs_public_key_compare to compare two
963 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
965 * Check that the client who set the founder mode on the
966 channel is the same client that is giving the founder
967 mode to itself. It is done by comparing the saved public
968 key (it is saved even in the authentication is passphrase).
969 Affected file silcd/command.c.
971 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
973 * Do not process packet for disconnected socket connection.
974 Affected file lib/silccore/silcpacket.c.
976 * Process the DISCONNECT packet through scheduler in the
977 client library. Affected file lib/silcclient/client.c.
979 * Fixed the silc_client_packet_parse to not to increase
980 the packet sequence number if the conn->sock and the
981 current socket connection is not same. This can happen
982 for example during key agreement when the conn includes
983 multiple socket connections (listeners). Affected file
984 lib/silcclient/client.c.
986 * The sender of the file transfer request now provides also
987 the pointer (listener) for the key exchange protocol. If
988 the listener cannot be created then it sends empty key
989 agreement and lets the receiver provide the listener.
991 Added `local_ip' and `local_port' arguments to the
992 silc_client_file_send. If they are provided they are used,
993 if not then it will attempt to find local IP address, if
994 not found or bind fails then the remote client will provide
997 Affected files are lib/silcclient/client_ftp.c and
998 lib/silcclient/silcapi.h.
1000 * Extended the FILE SEND command to support defining the
1001 local IP and port for key exchange listener. They are
1002 optional. Affected file irssi/src/silc/core/silc-servers.c.
1004 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Defined to WHOIS command reply the sending of fingerprint
1007 of the client's public key (if the proof of posession of the
1008 corresponding private key is verified by the server).
1009 Updated to the protocol specification.
1011 * Added support of receiving the client's public key's
1012 fingerprint in command reply in client library. Affected
1013 file is lib/silcclient/command_reply.c, and
1014 lib/silcclient/idlist.[ch].
1016 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Do not send over 128 chars long nickname to the server
1019 in NICK command. Affected file lib/silcclient/command.c.
1021 * Do not send over 256 chars long channel names to the server
1022 in JOIN command. Affected file lib/silcclient/command.c.
1024 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Assure that silc_server_close_connection cannot be called
1027 twice for same socket context. Affected file is
1030 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * Send error message to application if opening file for
1033 writing during file transfer fails. Affected file is
1034 lib/silcclient/client_ftp.c.
1036 Remove all file transfer sessions for a client that we're
1037 removing from ID cache.
1039 Affected file is lib/silcclient/client_ftp.c.
1041 * Fixed silc_net_addr2bin to return correct address. Affected
1042 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1044 * Fixed file transfer session removing on signoff notify.
1045 Affected file irssi/src/silc/core/silc-servers.c.
1047 * Added the SilcClientFileError to be returned in the monitor
1048 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1049 Affected file lib/silcclient/silcapi.h.
1051 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Fixed a crash in silc_client_ftp_free_sessions and
1054 silc_client_ftp_session_free_client. Affected file
1055 lib/silcclient/client_ftp.c.
1057 * Added `disabled' field in the SilcChannelEntry in the server
1058 to indicate if the server entry is disabled. Affected file
1059 silcd/idlist.h, silcd/command[_reply].c.
1061 * SILC server adds now /var/run/silcd.pid everytime it is
1062 started. Affected file silcd/silcd.c.
1064 * Added silc_server_packet_send_clients to send a packet to
1065 the provided table of client entries. Affected file
1066 silcd/packet_send.[ch].
1068 * Fixed a crash in client resolving in client_prvmsg.c in
1069 client library. Affected file lib/silcclient/client_prvmsg.c.
1071 * Do not actually remove the client directly from ID cache
1072 during SERVER_SIGNOFF, but invalidate it. This way we
1073 preserve the WHOWAS info for the client. Affected file
1074 silcd/server_util.c.
1076 * Fixed SERVER_SIGNOFF notify handling in the server. The
1077 server is now able to process incoming SERVER_SIGNOFF notify
1078 for a server that it doesn't even know about. It will remove
1079 the clients provided in the notify. Affected file
1080 silcd/packet_receive.c.
1082 * Check for partial packet in data queue after every packet that
1083 was found from the queue. Return and wait for more data if
1084 there is partial data in queue. Affected file is
1085 lib/silccore/silcpacket.c.
1087 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Added SilcClietFileError enum to indicate error in
1090 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1095 * Check that newsize in silc_buffer_realloc is larger than
1096 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1098 * Added better monitor of file transfers. It now monitors
1099 key agreement protocol during the file transfer too. Added
1100 error reporting too. Affected files
1101 irssi/src/silc/core/silc-servers.c,
1102 irssi/src/fe-common/silc/module-formats.[ch].
1104 * Wrote a help file for FILE command.
1106 * Added silc_rng_global_get_byte_fast to get not-so-secure
1107 random data as fast as possible. Random data is read from
1108 /dev/urandom if available and from the SILC RNG if not
1109 available. It is used in padding generation. Affected file
1110 lib/silccrypt/silcrng.[ch].
1112 * All packets in client library are now processed synchronously.
1113 Optimized packet processing a lot. Affected file
1114 lib/silcclient/client.c.
1116 * All server connection packets are processing synchronously
1117 now in server, to optimize packet processing. Affected file

1121 if make install is given. Affected files: all Makefile.am's.
1123 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Assure that silc_client_notify_by_server_resolve does not
1126 resolve the client information multiple times. If it cannot
1127 be found by the first it cannot be found at all. Affected
1128 file lib/silcclient/client_notify.c.
1130 * Fixed WHOWAS command reply calling. Affected file
1131 lib/silcclient/command_reply.c.
1133 * Removed all references to silc_idlist_get_client from the
1134 Irssi SILC client since that call is internal call used by
1135 the library. The Irssi SILC client will use now client
1136 retrieval functions found in silcapi.h.
1138 * Fixed a bug in resolving nickname info before sending
1139 private message. It used freed memory. Affected file
1140 irssi/src/silc/core/silc-servers.c.
1142 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1144 * Assure my_channels statistics cannot go negative in server.
1145 Affected files silcd/server.c, silcd/server_util.c.
1147 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1161 * Added silc_net_localip to return local host's IP address.
1162 Affected file lib/silcutil/silcnet.[ch].
1164 * If key exchange or rekey protocol is active for a connection
1165 parse all packets syncronously since there might be packets
1166 in packet queue that we are not able to process without first
1167 processing packets before them. Affected file silcd/server,
1168 lib/silcclient/client.c.
1170 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1171 whether library should continue processing the packet.
1172 Affected file lib/silccore/silcpacket.h.
1174 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1203 lib/silcutil/silcutil.[ch].
1205 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1207 * Resolve the client info when received private message or
1208 channel message for a client which nickname we don't know.
1209 Affected files lib/silcclient/client_prvmsg.c and
1210 lib/silcclient/client_channel.c.
1212 * Do not crash in /KEY if client is not connected. Affected
1213 file irssi/src/silc/core/silc-channels.c.
1215 * Added SilcClientStatus field to the SilcClientEntry in the
1216 lib/silcclient/idlist.h.
1218 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1219 is incomplete and is being resolved, it won't be resolved
1222 Make sure also that USERS command reply does not resolve
1223 twice information. Affected file is
1224 lib/silcclient/command_reply.c.
1226 Make sure that silc_client_get_clients_by_list does not
1227 resolve twice same information.
1229 * Check for valid client->id in the silc_server_free_client_data.
1230 Affected file silcd/server.c.
1232 * Fixed /GETKEY nick@server not to crash if the server entry
1233 is not found. Affected file lib/silcclient/command.c.
1235 * Fixed the silc_server_check_cmode_rights to check the
1236 requested modes correctly. Affected file silcd/command.c.

1240 * Better checks for non-printable chars in nick added.
1241 Affected file silcd/command.c.
1243 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * Call the silc_server_udpate_servers_by_server in the
1246 primary router that comes back online in the backup resuming
1247 protocol. Otherwise it routes packets wrong. Affected file
1248 silcd/server_util.[ch], silcd/server_backup.c.
1250 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1253 lib/silcutil/silcbuffmt.[ch].
1255 * Redefined the SILC packet header to include the padding
1256 length. Affected file lib/silccore/silcpacket.[ch].
1258 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1259 length for maximum padding up to 128 bytes). Affected
1260 file lib/silccore/silcpacket.h.
1262 * Removed all backwards support for old 0.5.x MAC thingies.
1263 The SILC packet header change makes it impossible to be
1264 backwards compatible.
1266 * Send the ENDING packet with timeout in the backup resuming
1267 protocol. This is to assure that all routers has connected
1268 to the primary router. Affected file silcd/server_backup.c.
1270 * Changed the RNG to take the first IV from random data. It
1271 used to take it from zero actually. Changed the RNG also
1272 to use /dev/urandom during session. /dev/random is used
1273 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1275 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Changed the SILC packet header to have the first two bytes
1278 (the packet length) encrypted. Affected files aroung the
1279 code tree, lib/silccore/silcpacket.[ch]. Removed the
1280 SilcPacketCheckDecrypt callback. It is not needed anymore
1281 since the silc_packet_receive_process will determine now
1282 whether the packet is normal or special.
1284 * Implemented the unidirectional MAC keys. Affected files
1285 lib/silcske/silcske.c, silcd/protocol.c and
1286 lib/silcclient/protocol.c.
1288 * Implemented the packet sequence number to the MAC computation.
1289 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1290 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1291 lib/silcclient/protocol.c.
1293 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Allow backup router to announce servers. All servers
1296 announced by backup router are added to the global list
1297 automatically. Update hte server's socket to our primary
1298 router also when backup router announces a server.
1299 Affected file silcd/packet_receive.c.
1301 * Do not update the client->router in the function
1302 silc_server_udpate_clients_by_server if the client is on
1303 global list. We might fail to find any specific server
1304 for locally connected clients and local cell clients. They
1305 should still use the `from' and not `to' as client->router.
1306 This fixes backup router resuming protocol. Affected file
1307 silcd/server_util.c.
1309 * Decrease channel statistics count only if the channel
1310 deletion worked. Affected files are silcd/server.c and
1311 silcd/server_util.c.
1313 * Added silc_server_update_servers_by_server to update origin
1314 of all server entries. Used during backup router protocol.
1315 Affected files silcd/server_util.[ch], silcd/server.c. and
1316 silcd/backup_router.c.
1318 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1319 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1320 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1321 lib/silccrypt/silchmac.c.
1323 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Assure that router cannot reroute the same channel message
1326 to the sender. Affected file silcd/packet_receive.c.
1328 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1330 * Made better checks that the channel message is not sent
1331 to the router it came from. Affected file is
1332 silcd/packet_send.c. Fixed memory leak too.
1334 * Announce informations for incoming router connection, but
1335 only after checking if it is replaced by backup router.
1336 Affected file silcd/packet_receive.c.
1338 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Fixed the backup resuming protocol to work in multiple
1341 router environment. Affected file silcd/server_backup.c.
1343 * Route packet only to one router in the function
1344 silc_server_packet_send_to_channel. Affected file is
1345 silcd/packet_send.c.
1347 * Fixed silc_server_send_notify_dest to set the broadcast
1348 flag. Fixed the silc_server_send_notify_topic to actually
1349 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1350 Affected file silcd/packet_send.c.
1352 * Changed the SFTP Filesystem interface. Changed the
1353 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1354 the filesystem operation function. The SilcSFTPFilesystem
1355 is now a context that is allocated by all filesystem allocation
1356 functions and it already includes the operations structure
1357 and filesystem specific context. It is given as argument
1358 now to the silc_sftp_server_start. This made the interface
1359 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1360 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1362 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Changed the backup router adding and getting interfaces
1365 in the server. The router that will be replaced by the
1366 specified backup router is now sent as argument. Affected
1367 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1370 * Added silc_net_addr2bin_ne to return the binary form of
1371 the IP address in network byte order. Affected files
1372 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1374 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Check for existing server ID in silc_server_new_server
1377 and in silc_server_connect_to_router_final and remove the
1378 old entry if it exists. Affected file silcd/packet_receive.c,
1381 * Send the channel message always to only one router, either
1382 in upstream or downstream. Affected file is
1383 silcd/packet_send.c.
1385 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Wrote the definition of the backup resuming protocol to the
1388 protocol specification.
1390 * Removed one redundant channel key generation from normal
1391 server during joining procedure. Removed one redundant
1392 channel key sending from server to router during joining
1393 procedure. Affected file silcd/command.c.
1395 * Made minor bugfixes to the backup router resuming protocol.
1396 Affected file silcd/server_backup.c, server.c.

1401 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1404 * Implemented the backup resuming protocol that is used to
1405 resume the primary router position in the cell after the
1406 primary router comes back online. Affected files
1407 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1408 and silcd/server_util.[ch].
1410 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Sleep two (2) seconds after sending QUIT command to server.
1413 Affected file lib/silcclient/command.c.
1415 * Assure that if outgoing data buffer is pending do not force
1416 send any data. Affected file silcd/packet_send.c.
1418 * Assure that if outgoing data buffer is pending do not force
1419 send any data. Affected file lib/silcclient/client.c.
1421 * Implemented the backup router support when the primary router
1422 goes down. The servers and routers can now use the backup
1423 router as new primary router without loosing connectivity.
1425 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1427 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1428 in the server to indicate disabled entry. All data read
1429 from the connection will be ignored and no data is sent
1430 for entry that is disabled. Affected files are
1431 silcd/idlist.h, silcd/server.c.
1433 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Created SFTP client and server test programs in the
1436 lib/silcsftp/tests directory.
1438 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Implemented memory filesystem (virtual filesystem) for
1441 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1444 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Implemented the SFTP (SSH File Transfer Protocol) to the
1447 lib/silcsftp. It includes SFTP client and SFTP server
1450 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Moved lib/silccore/silcprotocol.[ch] to the
1453 lib/silcutil library.
1455 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1456 take variable argument list pointer as argument. Affected
1457 file lib/silcutil/silcbuffmt.[ch].
1459 * Added silc_buffer_set function that is used to set data
1460 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1461 Affected file lib/silcutil/silcbuffer.h.
1463 * Changed various routines in the core library to use the new
1464 silc_buffer_set instead of allocating new buffer only for
1467 * Added 64-bit value formatting and unformatting support to the
1468 silc_buffer_[un]format routines. Affected file is
1469 lib/silcutil/silcbuffmt.[ch].
1471 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1472 to includes/bitmove.h.
1474 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Fixed channel user mode saving in client library. Affected
1477 file lib/silcclient/command[_reply].c.
1479 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Defined the file transfer to the SILC Protocol. Added
1482 new packet type SILC_PACKET_FTP and defined File Transfer
1483 Payload. The mandatory file transfer protocol is SFTP
1484 (SSH File Transfer Protocol). Affected file in addition
1485 of the internet draft is lib/silccore/silcpacket.h.
1487 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1488 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1489 is used as part of backup router protocol when the primary
1490 router of the cell is back online and wishes to resume
1491 the position as primary router.
1493 * Redefined the MAC generation keys in the protocol. The
1494 same key is not used anymore in both direction. Both
1495 direction will now use different keys for sending and
1496 receiving. This fixes a potential security flaw. This
1497 change causes incompatibilities in the protocol.
1499 * Redefined also the MAC computation from the packet.
1500 An packet sequence number is now added to the MAC
1501 computation. This prevents possible replay attacks against
1502 the protocol. This change too causes incompatibilities
1505 Added `sequence' field to the SilcPacketContext to hold
1506 the current sequence number for the packet.
1508 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Added `created' field to the SilcIDListData in the file
1511 silcd/idlist.h to indicate the time when the entry was
1514 * Added `created' field to the SilcChannelEntry too. Affected
1515 file silcd/idlist.h.
1517 * Added `creation_time' aguments to all the announcement functions
1518 in the server. If it is provided then only the entries that
1519 was created after the provided time frame are actually
1520 announced. Affected file silcd/server.[ch].
1522 * The protocol says that the Channel ID's IP address must be
1523 based on the router's IP address. Added check for this in
1524 the silc_server_new_channel when processing incoming New Channel
1525 Payload. Affected file silcd/packet_receive.c.
1527 * Print out the correct version with --version in SILC client.
1528 Affected file irssi/src/silc/core/silc-core.c.
1530 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Fixed WHOWAS command to check for completnes of the client
1533 entry always, not just when the command is coming from client.
1534 Affected file silcd/command.c.
1536 * Added new function silc_server_packet_queue_purge to purge the
1537 outgoing data queue to the network. After the function returns
1538 it is guaranteed that the outgoing packet queue is empty.
1539 Affected file silcd/packet_send.[ch].
1541 * Purge the outgoing packet queue in the rekey protocol's final
1542 callback to assure that all rekey packets go to the network
1543 before quitting the protocol. Affected file silcd/server.c.
1545 * Added silc_client_packet_queue_parse as similar function as
1546 in server to the client library. The affected file is
1547 lib/silcclient/client.c.
1549 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Splitted silcd/server.c and created silcd/server_util.[ch]
1552 for utility functions.
1554 * Added new socket flag SILC_SF_DISABLED to indicate that the
1555 connection is open but nothing can be sent to or received from
1556 the connection. Affected file lib/silcutil/silsockconn.[ch].
1557 The checking for disabled socket is checked in the low level
1558 silc_socket_write and silc_socket_read functions.
1560 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Allow only nicknames and channel names that fits into the
1563 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1565 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * When processing JOIN command reply in server check that if
1568 the channel exists in our global list we'll move it the local
1569 list. Affected file silcd/command_reply.c.
1571 * Fixed the check whether client is joined on the channel already
1572 in JOIN command. Affected file lib/silcclient/command.c.
1574 * Fixed the JOIN command reply to check whether the channel
1575 already exists. Affected file lib/silcclient/command_reply.c.
1577 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Added silc_ske_status_string to map the SKE error numbers
1580 to readable strings. The affected files are
1581 lib/silcske/silcske[_status].[ch].
1583 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1585 * Do not show the private channels on the WHOIS channel list
1586 as it is not allowed by the protocol. The affected file is
1589 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Assure that the packet length digged from the actual packet
1592 is something sensible in the silc_packet_decrypt_rest_special
1593 in lib/silccrypt/silcpacket.c.
1595 * Free and NULL the allocated pointer in silc_hmac_alloc if
1596 the HMAC allocation fails. The affected file is
1597 lib/silccrypt/silchmac.c.
1599 * Print the selected security properties to the log files in
1600 the server. Affected file silcd/protocol.c.
1602 * Add SKE's reference counter even if calling the completion
1603 callback manually. Otherwise it goes negative, although it
1604 does not cause any problems. The affected file is
1605 lib/silcske/silcske.c.
1607 * Remove the client entry with short timeout after giving the
1608 KILL command. Affected file lib/silcclient/command.c.
1610 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1611 case all found clients are already disconnected (WHOWAS would
1612 found them) in the server. Affected file silcd/command.c.
1614 * Update the last_receive (time of last data received) to be
1615 updated only when received private or channel message so that
1616 the idle time showed in WHOIS makes more sense.
1618 * Added boolean field `valid' in to the SilcClientEntry in the
1619 client library to indicate whether the entry is valid or not.
1620 This fixes the nickname change bug on channel when changing
1621 the nickname to be same than the old (like nick to Nick) the
1622 nickname formatter doesn't set the new nick anymore to Nick@host.
1623 Affected file lib/silcclient/idlist.[ch].
1625 * Now actually fixed the nickname changing on disconnection.
1626 Added new function silc_change_nick to the Irssi SILC Client.
1627 Affected file irssi/src/silc/core/client_ops.c,
1628 irssi/src/silc/core/silc-nicklist.[ch].
1630 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Check that the public key exists in the GETKEY command before
1633 trying to encode it. Affected file silcd/command.c.
1635 * Print some notifications on received public keys with GETKEY
1636 command in the Irssi SILC Client. Affected files are
1637 irssi/src/fe-common/silc/module-formats.[ch],
1638 irssi/src/silc/core/client_ops.c.
1640 * Use IDENTIFY command to resolve the server information in the
1641 GETKEY command instead of INFO command. Affected file
1642 lib/silcclient/command.c.
1644 * All command reply functions in the client library now calls
1645 the pending command reply callbacks even if an error has
1646 occurred. The server has done this a long time and now it was
1647 time to move the client library to this as well. Now all
1648 errors can be delivered back to the pending command reply
1649 callbacks if necessary. Affected files are
1650 lib/silcclient/command[_reply].[ch].
1652 * Change the nickname on disconnection back to the username
1653 because in reconnect the server will enforce it to it anyway.
1654 Affected file irssi/src/silc/core/silc-servers.c.
1656 * Fixed a config file parsing bug in the Irssi SILC client.
1657 Affected file irssi/src/silc/core/clientconfig.c.
1659 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * When printing the channel mode on JOIN, verify that the
1662 channel key and channel's HMAC are valid. Affected file
1663 irssi/src/silc/core/client_ops.c.
1665 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1668 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1669 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1671 * Removed channel key rekey task deleting from the function
1672 silc_server_save_channel_key. Affected file silcd/server.c.
1673 Added explicit timeout task context instead that is used to
1674 delete the task if we are registering a new task before the
1675 new task has elapsed.
1677 * When channel key rekey occurs the client library now saves
1678 the old channel key for a short period of time (10 seconds) and
1679 is able to use it in case some is still sending channel
1680 messages encrypted with the old key after the rekey. Affected
1681 file lib/silcclient/[idlist.h|client_channel.c].
1683 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Added check to the silc_server_new_id_real to not accept
1686 new ID if it is the sender's own ID. Affected file is
1687 silcd/packet_receive.c.
1689 * Assure that we do not announce ourself or the one we've
1690 sending our announcements when we're router and are announcing
1691 servers to our primary router. Affected file silcd/server.c.
1693 * Fixed silc_server_command_identify_check_client to assemble
1694 correct WHOIS packet. It send corrupted WHOIS packet and
1695 caused problem with router to router connections. Affected
1696 file silcd/command.c.
1698 Fixed also silc_server_command_whois_check the same way
1699 as for the IDENTIFY command.
1701 * Added new SilcIDListStatus to the server in the SilcIDListData
1702 structure. The status now includes the current status of
1703 the entry (like registered, resolved etc.). Affected file
1704 silcd/idlist.[ch]. Defined a bunch of different status types
1705 as well. This replaced the old boolean registered field as well.
1707 Added resolve_cmd_ident field to the SilcClientEntry structure
1708 too so that if the entry is for example being resolved so
1709 another command may attach to the same pending command reply
1710 without requiring to resolve the same entry again. This concept
1711 should optimize the WHOIS and the IDENTIFY resolving under
1712 heavy load by taking away unnecessary resolving for entries
1713 that are being resolved already.
1715 Added support for adding multiple pending commands for one
1716 command idenfier. Affected file silcd/command[_reply].[ch].
1718 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1719 before deleting the data. Otherwise the hash table will have
1720 freed data in comparison functions. Affected file is
1721 silcd/command_reply.c.
1723 * Fixed silc_idlist_replace_client_id to add the new entry to
1724 the cache with NULL nickname. Otherwise there will be invalid
1725 memory as the nickname after the nickname is freed. Affected
1726 file silcd/packet_receive.c.
1728 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1729 saved into wrong slots because the previous number of entries
1730 was not taken into account. Affected file silcd/idlist.c.
1731 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1733 * If we are router and we receive JOIN notify to a channel that
1734 does not have any users then notified client is marked as the
1735 channel founder, as it is it. The affected file is
1736 silcd/packet_receive.c
1738 * Added to the extended hash table API's table_del_*ext functions
1739 the destructor as argument too, so that the caller can decide
1740 which destructor to use or whether to use destructor at all.
1741 Affected file lib/silcutil/silchashtable.[ch].
1743 * Fixed ID Cache purging. It actually deleted the entries from
1744 the hash table after the data was freed. The hash table ended
1745 up comparing freed memory. The affected file is
1746 lib/silccore/silcidcache.c.
1748 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Fixed Irssi SILC client's KILL command's HELP syntax.
1752 * The USERS command now resolves the detailed user information
1753 if the userinfo field is missing. Affected file is
1754 lib/silcclient/command_reply.c.
1756 * Do not print error in silc_file_read if the read file does
1757 not exist. Just silently return NULL. Affected file is
1758 lib/silcutil/silcutil.c.
1760 * Fixed the silc_log_output to not wine about NULL filename
1761 and to not create some bogus " " filename. Affected file is
1762 lib/silcutil/silclog.c.
1764 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Fixed various printing bugs on the user interface in the
1767 Irssi SILC Client. Minor changes that were forgotten from
1770 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1772 * Fixed the configure.in.pre and the compilation and distribution
1773 environment to support the new autoconf 2.52. That version is
1774 now required to compile the CVS trunk.
1776 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1779 to generally parse user@fqdn format strings. Affected file
1780 lib/silcutil/silcutil.c.
1782 * Added nickname_format and nickname_force_format fields to the
1783 SilcClientParams structure. The first one defines the format
1784 for the nicknames that the library will enforce if the receives
1785 multiple same nicknames. The second one is boolean value and
1786 can be used to force the library to always enforce the format
1787 to the nicknames regardles whether there are multiple nicknames
1788 or not. This configurable formatting was employed to flexibly
1789 support accessing multiple nicknames from the user interface.
1790 The userinterface can now set the nicknames to what ever format
1791 they prefer. Affected file lib/silcclient/silcapi.h.
1793 Added function silc_client_nickname_format to the file
1794 lib/silcclient/idlist.c. It performs the nickname formatting.
1796 Added new field `hostname´ to the SilcClientEntry context.
1797 It holds the hostname of the client. Affected file is
1798 lib/silcclient/idlist.h.
1800 * Irssi SILC Client sets the nicknames in nick@hostn format.
1801 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1802 irssi/src/silc/core/silc-core.c.
1804 The WHOIS printing now also shows both the real nickname and
1805 the formatted nickname so that user knows how to access the
1806 user if there are multiple same nicknames cached. Affected
1807 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1808 printing formatting too to take the hostname now as a separate
1809 argument. The Affected file is
1810 irssi/src/fe-common/silc/modules-formats.[ch].
1812 * Changed the silc_client_get_clients_local to accept the formatted
1813 nickname as argument. It accepts the real nickname too but the
1814 formatted nickname can be used to find the true entry from
1815 multiple entries. Affected file lib/silcclient/silcapi.h and
1816 lib/silcclient/idlist.c.
1818 * Added nickname_format_parse field to the SilcClientParams.
1819 It is a callback function provided by the application to parse
1820 the nickname out of the formatted nickname string. The library
1821 calls it to get the nickname from the formatted string. Since
1822 the application generally knows better the format of the nickname
1823 string it parses it instead of the library, even though library
1824 encodes the formatted string. If the callback function is not
1825 provided then the library will use the string as is. The
1826 affected file is lib/silcclient/silcapi.h.
1828 * All the nickname strings passed to the client library in
1829 commands are now expected to be formatted nickname strings.
1830 If the command does not support the formatted nickname string
1831 it will assume that the sent string is the actual nickname.
1832 Affected file lib/silcclient/command.c.
1834 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Added public key authentication support to OPER and SILCOPER
1837 commands in the client library. Affected file is
1838 lib/silcclient/command.c.
1840 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * Changed the get_auth_methdod client operation to be asynchronous.
1843 It can be async if the application resolves the authentication
1844 method from the server during the negotiation. Added new
1845 SilcGetAuthMeth completion callback that the application will
1846 call after resolving the authentication method.
1848 Added function silc_client_request_authentication_method that
1849 the application can use to resolve the authentication method
1850 from the server. Added also SilcConnectionAuthRequest callback
1851 that the library will call after the server has replied. The
1852 application can call this function if it does not know the
1853 current authentication method.
1855 Affected files are lib/silcclient/client.c and
1856 lib/silcclient/silcapi.h.
1858 * The Irssi SILC client now automatically resolves the authentication
1859 method incase any configuration information is not present (and
1860 currently there never is). The affected file is
1861 irssi/src/silc/core/client_ops.c.
1863 * Fixed public key authentication from the client library.
1864 Affected file lib/silcclient/protocol.c. Changed also the
1865 protocol specification about the public key authentication in
1866 the connection authentication protocol. The actual data to be
1867 signed is now computed with a hash function before signing.
1869 * Fixed the public key authentication from the server as well.
1870 Affected file silcd/protocol.c.
1872 * Removed the mlock()'s from the memory allocation routines.
1873 Affected file lib/silcutil/silcmemory.c. The ./configure does
1874 not check anymore for the mlock(). Affected file is
1877 * Fixed USERS command in server to allow the execution of the
1878 command for private and secret channels if the client sending
1879 the command is on the channel. Affected file silcd/command.c.
1881 * Fixed silc_client_get_clients_local to return the clients
1882 count correctly. It could return wrong value. Affected file
1883 lib/silcclient/idlist.c.
1885 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1888 types. The assembler optimizations seemed not to like 64-bit
1889 data types. The assmebler optimizations thus are now enabled
1890 also for BSD systems as opposed to only enable them for Linux.
1892 * Do not check for threads at all on BSD systems. Affected
1893 file configure.in.pre.
1895 * Removed -n and -h options from the Irssi SILC Client since
1896 they are not used in silc.
1898 * Fixed the prime generation to assure that the first digit
1899 of the generated random number is not zero since our conversion
1900 routines does not like number strings that starts with zero
1901 digit. If zero digit is seen the random number is regenerated.
1902 This caused some corrupted RSA keys when the zero first digit
1903 was met. Affected file lib/silcmath/silcprimegen.c.
1905 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Fixed WIN32 configuration in the ./configure script.
1908 Fixed to include xti.h on environments that has it.
1909 Patches by Carsten Ilchmann and andrew.
1911 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Changed the silc_id_create_client_id to be collision
1914 resistant. It is now assured that there cannot be created
1915 two same client ID's. I suspect that some weird bugs in
1916 the server were actually caused by duplicate Client IDs.
1917 Affected file silcd/serverid.[ch]. A router receiving
1918 new ID now also assures and informs the sending server
1919 if the ID caused collision.
1921 * Changed the silc_id_create_channel_id to also assure that
1922 there are no collisions.
1924 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Statement about ignoring the Mutual Authentication flag when
1927 performing rekey with PFS was a bit misleading. It is ignored
1928 if it was set in the initial negotiation, it cannot be even
1929 set in the rekey. Fixed in the ke-auth draft. Started the
1930 new versions of the protocol drafts in the doc/.
1932 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Fixed a bug in silc_client_command_identify_save when saving
1935 new channel information. The channel name was no duplicated
1936 and caused crash on exit. Affected file is
1937 lib/silcclient/command_reply.c.
1939 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Fixed the getkey command handling in the server. Send just
1942 empty OK reply to the sender if the key could not be fetched
1943 (but everything else was ok, like the key just was not available).
1944 Changed the public key parameter to optional in the protocol
1945 specs so that empty OK reply can be sent. Affected file
1948 Added a message to Irssi SILC client to tell to user if the
1949 server did not return a public key.
1951 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Fixed a channel key regeneration bug. It registered new
1954 timeout tasks exponentially until all system resources were
1955 used. Affected file silcd/server.c.
1957 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1959 * Added the SILC Document generator to the scripts/silcdoc.
1960 It can be used to generate the Toolkit Reference Manual out
1961 of the source tree. Internally it will also use the RoboDoc
1962 generator now imported in util/robodoc.
1964 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * Added couple of return's in rekey protocol if error orccurred
1967 during the protocol. The execution must be terminated.
1968 Affected file silcd/protocol.c. Also, terminate the protocol
1969 always with timeout.
1971 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * The client's Client ID was created initally from the wrong
1974 nickname (it could have been in format nick@host) in the
1975 silc_server_new_client. Affected file silcd/packet_receive.c
1977 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Added some SILC_LOG_ERROR's to various error conditions
1980 if client could not be added to ID cache. Affected files
1981 silcd/packet_receive.c and silcd/server.c.
1983 * When client's sock->user_data is freed, NULL also the
1984 client->router and client->connection pointers. Added check
1985 for these pointers being NULL to various places around the
1986 code. Affected file silcd/server.c.
1988 * Added client->data.registered == TRUE checks to various
1989 places around the code to assure that unregistered client's
1990 are not handled when it is not allowed. Affected file
1993 * Added `bool registered' fields to all
1994 silc_idlist_[server|client]_get_* routines to indicate whether
1995 the fetched client needs to be registered or not. Affected
1996 file silcd/idlist.[ch].
1998 * Add your own entry as registered to the ID cache in the
1999 server. Affected file server.c.
2001 * Fixed a bug in silc_server_new_server. The SilcServer was
2002 set as the new server's context instead of SilcServerEntry.
2003 This naturally caused some weird bugs.
2005 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Do not delete the channel rekey task when adding it
2008 for in silc_server_create_channel_key.
2010 * Changed the silc_server_create_channel_key to return
2011 TRUE or FALSE to indicate the success of the channel key
2014 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * Fixed MSVC++ project files and added missing files to
2017 Makefiles under win32/.
2019 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Do not add TCP_NODELAY flag if the operating system
2022 does not have it defined. Affected files are
2023 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2025 * Fixed buffer overflow from Irssi SILC Client. Affected
2026 file irssi/src/fe-common/core/themes.c.
2028 * Fixed double free in client library in the file
2029 lib/silcclient/client.c when disconnecting from server.
2031 * Applied double free patch from cras to Irssi SILC client.
2032 Affected files irssi/src/core/[modules/expandos].c
2034 * Fixed the disconnection handling to Irssi SILC Client.
2035 The application must call silc_client_close_connection
2036 in ops->connect client operation in case of failure of
2037 the connection. Affected file is
2038 irssi/src/silc/core/client_ops.c.
2040 * Do not set sock->protocol to NULL in the function
2041 silc_client_close_connection after executing the protocol's
2042 final callback since the sock might not be valid anymore.
2043 Affected file lib/silcclient/client.c.
2045 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Do not enable SILC_THREADS if the linking with libpthread
2048 did not happen. Affected file configure.in.pre.
2050 * Added notion to protocol specification that server must
2051 verify the sent authentication payload with CMODE when
2052 setting the channel founder key. Implemented it to the
2053 server. Affected file silcd/command.c.
2055 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2057 * Added _EXTRA_DIST SILC distribution variable to the
2058 distributions file. It is used to conditionally add extra
2059 files or directories to the specific distribution. Affected
2060 files ./prepare, Makefile.am.pre and distributions.
2062 Removed the `_' from the start of the distribution names.
2065 * Added README.WIN32 for instructions to compile the Toolkit
2068 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Fixed a double free in disconnection in the server. Affected
2071 file is silcd/server.c.
2073 * Fixed the lib/silcske/groups.c to work now also with GMP
2074 MP library. The string conversion did not work when using
2075 specific base and the base is indicated in the string as well.
2077 * Created win32/ directory which now includes MSVC++ specific
2078 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2079 It will appear only in the toolkit distribution
2081 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2083 * Changed the key material distribution function in case when
2084 the hash output is too short. The data is now concatenated
2085 a bit differently than it used to. Made the change to the
2086 SKE protocol specification.
2088 * Added better GMP detection to configure.in.pre. A patch
2091 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2093 * Fixed a minor bug in SKE that might cause some problem on
2094 some platforms. Affected file lib/silcske/silcske.c.
2096 * Added the cookie checking for initiator in the SKE. It checks
2097 that the responder returns the sent cookie unmodified. The
2098 affected file is lib/silcske/silcske.c. Added new SKE
2099 error type INVALID_COOKIE that can be sent during the
2100 negotiation. Fixed some memory leaks as well.
2102 * Added the "invalid cookie" error message to Irssi SILC client's
2105 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Added `task_max' field to the SilcClientParams to indicate
2108 the maximum tasks the scheduler can handle. If set to zero,
2109 default values are used. Affected file lib/silcclient/silcapi.h.
2111 * Fixed memory leaks in silc_client_close_connection. Affected
2112 file lib/silcclient/client.c.
2114 * Added silc_client_del_client_entry to client library to free
2115 all memory of given client entry. Affected file is
2116 lib/silcclient/idlist.[ch].
2118 * Added new functions silc_client_del_channel and
2119 silc_client_del_server to delete channel and server entries.
2120 Affected file lib/silcclient/[silcapi.h/idlist.c].
2122 * Removed silc_client_del_client_by_id from silcapi.h.
2124 * Fixed the INFO command to return the server's own info
2125 correctly when querying by Server ID. Affected file is
2128 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Removed the non-blocking settings in WIN32 code in the
2131 silc_sock_[read/write] and added SleepEx instead. Affected
2132 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2133 of input data is now checked with FIONREAD and ioctlsocket.
2135 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Call silc_schedule_task_del_by_context in the
2138 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2139 Affected file lib/silccore/silcprotocol.c.
2141 * Call silc_protocol_cancel for active protocols in the
2142 silc_server_close_connection if the funtion
2143 silc_server_free_sock_user_data has not been called.
2144 Affected file silcd/server.c.
2146 * Generic tasks cannot be deleted using the del_by_fd
2147 task deleting function since generic tasks does not match
2148 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2150 * Added a notion to SILCOPER help file that the SILCOPER works
2151 only on router server, not on normal server.
2153 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Added for WIN32 support for the new scheduler as well.
2156 Affected file lib/silcutil/win32/silcwin32schedule.c.
2158 * Fixed the SHA1 implementation to work on various platforms.
2160 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2162 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2163 API. It is part of the scheduler now. Everything else is
2164 as previously but some functions has changed their names.
2165 Checkout the lib/silcutil/silcschedule.h for the interface.
2166 Updated all applications to use the new interface. Affected
2167 files are lib/silcutil/silcschedule.[ch].
2169 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2171 * Found a bug in the SKE implementation. The HASH value,
2172 specified by the protocol, was not computed correctly. The
2173 public key of the responder was not added to the computation
2174 even though it is mandatory. Affected file lib/silcske/silcske.c.
2175 This unfortunately causes incompatibilities with older
2176 clients and servers.
2178 * Added WIN32 specific network init and uninit functions:
2179 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2180 the Winsock2. Affected file lib/silcutil/silcnet.h and
2181 lib/silcutil/win32/silcwin32net.c.
2183 * Set the socket always to nonblocking mode on WIN32 after
2184 reading data or writing data. Affected file is
2185 lib/silcutil/win32/silcwin32sockconn.c.
2187 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Fixed various compilation problems under WIN32. Affected
2190 files lib/silcutil/win32/silcwin32thread.c and
2191 lib/silcutil/win32/silcwin32schedule.c.
2193 * Removed all _internal.h #includes from public header
2194 files. Internal headers must never be included from
2197 Removed also the lib/silcske/payload_internal.h file.
2199 * All include files that may be needed (public and some others
2200 included by the public headers) by application developers are
2201 now copied to the ./includes directory. It does not copy any
2202 internal headers. Affected file Makefile.defines.pre and all
2203 Makefile.am's under lib/ and subdirs.
2205 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2207 * Do not change the ~/.silc directory's permissions automatically.
2208 Affected file irssi/src/silc/core/clientutil.c.
2210 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Do not cancel the protocol in silc_server_close_connection
2213 it might cause recursion. Now cancelled in the function
2214 silc_server_free_sock_user_data. Affected file silcd/server.c.
2216 * Fixed the silc_server_remove_clients_by_server to regenerate
2217 the channel keys correctly finally. Added also new function
2218 silc_server_remove_clients_channels to actually do it.
2219 Affected file silcd/server.c.
2221 * Fixed the silc_server_new_channel to not crash by giving
2222 wrong router to the new channel. Affected file is
2223 silcd/packet_receive.c.
2225 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2227 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2228 which is given as argument to the silc_client_alloc now.
2229 It can be used to configure the client and set various parameters
2230 that affect the function of the client.
2232 * The USERS command in server did not check whether the channel
2233 is private or secret. Affected file silcd/command.c.
2235 * Added new argument to the USERS command in protocol specification.
2236 The USERS command now can take the channel name as argument
2237 as well. Added support for this in client and server and
2238 updated the protocol specs.
2240 * Completed the GETKEY command in client. It can be now used
2241 to fetch also servers public key not only some clients.
2242 Affected files lib/silcclient/command[_reply].c.
2244 * Added silc_client_get_server to return server entry by the
2245 server name. Affected files lib/silcclient/silcapi.h and
2248 * Redefined the IDENTIFY command in protocol specification to be
2249 more generic. It now can be used to query information about
2250 any entity in the SILC Network, including clients, servers and
2251 channels. The query may be based either the entity's name
2252 or the ID. Added support for this in both client and server.
2254 Affected files silcd/command.c and lib/silcclient/command.c
2255 and command_reply.c.
2257 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2258 the _from_client and _from_server functions. Affected file
2261 * Added silc_client_get_channel_by_id_resolve to the file
2262 lib/silcclient/silcapi.h to resolve channel information by
2263 its ID. Added also silc_client_get_channel_by_id that
2264 does not resolve it from the server.
2266 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Added SilcServerEntry context into the client library
2269 to represent one server. The INFO command now allocates
2270 these to save the resolved server info. For now on the
2271 client library will also keep information about servers,
2272 connected and resolved with INFO.
2274 The INFO command now allocates the SilcServerEntry context
2275 and saves the server info there. The COMMAND_REPLY in
2276 the INFO now returns the parameters to application in
2277 same order as defined in the protocol specification.
2279 The entries are cached in the client->server_cache.
2281 * The INFO command is now issued after received the Client ID
2282 from the server. Affected file lib/silcclient/client.c.
2284 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2285 to the application as the mode changer might be server.
2286 It is guaranteed that NULL is not returned anymore to the
2287 application. Affected file lib/silcclient/client_notify.c.
2289 The ID Type is now also passed to the application so that
2290 it can check whether the returned entry is SilcClientEntry
2293 Added new function silc_client_get_server_by_id to return
2294 the server entry by ID. Affected files are the
2295 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2297 * Do not create the channel in the Irssi SILC Client when issuing
2298 the JOIN command but when received the sucessful JOIN command
2299 reply. Otherwise the channel might get created even though we
2300 could not join it. The Affected file is
2301 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2303 * Fixed a channel joining bug in router. The router must also
2304 check the channel modes, invite and ban lists etc. when serving
2305 the JOIN command sent by normal server. Affected file is
2306 silcd/command.c. The router now resolves the client's
2307 information from the server who sent the JOIN command if it
2308 does not know it, and processes the JOIN command only after
2311 * Changed the SilcCommandCb to take new argument; void *context2.
2312 Affected file lib/silccore/silccommand.h
2314 The second argument in the command callbacks in the server now
2315 includes the SilcServerCommandReplyContext if the command was
2316 called as pending command callback from the command reply.
2317 Otherwise it is NULL. When called as pending the status of the
2318 command reply will be checked and if it was erronous the
2319 error will be sent to the original sender of the command.
2320 This way the client always receives the error messages even
2321 though the server was actually the one who received the error
2322 when it resent the command to router, for example. Affected
2323 files silcd/command[_reply].[ch].
2325 * Fixed sending WHOWAS command's error message to client if
2326 the requested client could not be found. It was missing.
2329 * Changed the CMODE and CUMODE commands reply arguments in the
2330 protocol specification. The Channel ID is now sent in both
2331 of the commands to identify the channel. Implemented this
2332 new feature to the client and server. Affected files
2333 lib/silcclient/command_reply.c and silcd/command.c.
2335 * Made better checks for invite and ban lists in the JOIN
2336 command in server. Affected file silcd/command.c.
2338 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * The server now performs the incoming host IP/DNS lookup
2341 using the silc_socket_host_lookup and thus does not block
2342 the server anymore. Affected file silcd/server.c.
2344 * Completed the multi-thread support for SILC Scheduler in
2345 the lib/silcutil/silcschedule.c.
2347 * Fixed the configure.in.pre to detect the pthread correctly
2350 * Fixed a deadlock in silc_task_queue_wakeup in the file
2351 lib/silcutil/silctask.c.
2353 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Added new function silc_schedule_wakeup that is used in
2356 multi-threaded environment to wakeup the main thread's
2357 schduler. It needs to be used when a thread adds a new task
2358 or removes a task from task queues. After waking up, the
2359 scheduler will detect the task queue changes. If threads
2360 support is not compiled in this function has no effect.
2361 Implemented the wakeup mechanism to both Unix and WIN32
2362 systems. Affected files are lib/silcutil/silcschedule.[ch],
2363 lib/silcutil/unix/silcunixschedule.c and the
2364 lib/silcutil/win32/silcwin32schedule.c.
2366 * Added new function silc_task_queue_wakeup to wakeup the
2367 scheduler by the specified task queue. Affected file
2368 lib/silcutil/silctask.[ch].
2370 * The silc_socket_host_lookup_start now wakes up the scheduler
2371 after adding the timeout task. Affected file is
2372 lib/silcutil/silcsockconn.c.
2374 * The silc_socket_host_lookup is synchronous now if the threads
2375 support is not compiled in. However, the callback is still
2376 called asyncronously through the scheduler, anyway. Affected
2377 file lib/silcutil/silcsockconn.c.
2379 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Added new function silc_socket_host_lookup to perform
2382 asynchronous IP and FQDN lookups for the socket connection.
2383 Affected files lib/silcutil/silcsockconn.[ch].
2385 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2388 that may or may not compile the mutex support in.
2390 Changed the silc_mutex_alloc interface. It allocates the
2391 mutex now to the sent pointer and returns TRUE or FALSE.
2393 Affected file lib/silcutil/silcmutex.h.
2395 * Wrote the SILC Task Queue interface to support multi-threads.
2396 Affected file lib/silcutil/silctask.[ch].
2398 * Wrote the SILC Scheduler to support multi-threads. Affected
2399 file lib/silcutil/silcschedule.c.
2401 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2404 in lib/silcutil/win32/.
2406 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Defined SILC Mutex API and SILC Thread API and implemented
2409 them for Unix. Affected files are
2410 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2411 lib/silcutil/unix/silcunixmutex.c and
2412 lib/silcutil/unix/silcunixthread.c.
2414 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Fixed the silc_server_remove_clients_by_server's channel
2417 key re-generation. The hash table handling was incorrect
2418 and would not work with many channels. Affected file is
2421 * Fixed some memory leaks around the server code.
2423 * Rewrote the silc_server_get_users_on_channel to support IPv6
2424 based Client ID's. Affected file silcd/server.c.
2426 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2427 specification. However, a separate document must be written
2428 to define the detailed signing procedure and the payload
2429 associated with the flag. Defined the flag to the
2430 lib/silccore/silcchannel.h as well.
2432 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Changed the dynamic tables to static size tables in the
2435 lib/silccrypt/silchmac.c.
2437 * Removed GCC dependencies from the code. A patch by cras.
2439 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Do not show the error "Error receiving packet bla bla"
2442 in server if it really was not an error (-2 means that reading
2443 is pending). Affected file silcd/server.c.
2445 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2447 * Fixed a possible crash in silc_server_remove_clients_by_server
2448 in silcd/server.c. Fixed there also some memory leaks.
2450 * Fixed the silc_idlist_replace_client_id. It could replace
2451 wrong key in the hash table. Affected file silcd/idlist.c.
2453 * Do not check whether there are global users on the channel
2454 if the channel->global_users is FALSE. Affected functions
2455 silc_server_remove_from_one_channel and
2456 silc_server_remove_from_channels in silcd/server.c. Also,
2457 do not check if the removed client is local as we can be
2458 sure that global client was not removed from the channel
2459 and checking for global users is not needed.
2461 * The silc_server_remove_clients_by_server now re-generates
2462 the channel keys correctly for those channels that had
2463 clients removed from them. Affected file silcd/server.c.
2465 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Found the reason of random crashes in the server. We weren't
2468 ignoring the SIGPIPE signal (which can be sent in write())
2469 and it crashed the server. Affected file silcd/silcd.c.
2471 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2473 * Assure that sock->user_data is not NULL in the function
2474 silc_server_packet_send in silcd/packet_send.c.
2476 * Disconnect the remote connection if it could not be added
2477 to any ID lists in the server. The affected file is
2480 * Check in silc_server_packet_send[_real/dest] that the
2481 socket is not disconnecting and ignore the data if it is.
2482 Affected file silcd/packet_send.c.
2484 * Define inline to __inline on native WIN32 compilation.
2485 Affected file includes/silcwin32.h.
2487 * Added some explicit type casts for inline code since MSVC
2488 require them. Affected files lib/silcutil/silcbuffer.h,
2489 lib/trq/silcdlist.h and lib/trq/silclist.h.
2491 * Print warning in log files from now on if the packet
2492 decryption fails. Affected file silcd/server.c.
2494 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2496 * Changed the `say' client operation's interface to accept
2497 new `type' argument to indicate the type of the message sent
2498 by the library. The application may filter the library's
2499 messages according the type. The affected file is the
2500 lib/silcclient/silcapi.h.
2502 * Added two new functions to lib/silcclient/silcapi.h:
2503 silc_client_del_client and silc_client_del_client_by_id.
2504 Affected file lib/silcclient/idlist.c.
2506 * Moved the clientincludes.h from includes/ to silc/ and
2507 serverincludes.h from includes/ to silcd/.
2509 * The modes for the CMODE and CUMODE are now passed as
2510 uint32 for application with COMMAND_REPLY. The affected
2511 file is lib/silcclient/command_reply.c.
2513 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2515 * /WHOIS without arguments shows client's own information.
2516 Affected file lib/silcclient/command.c.
2518 * Changed PING to not accept any arguments. The specs
2519 says that client can ping only the connected server so
2520 requiring an argument is not needed. Affected file is
2521 lib/silcclient/command.c.
2523 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2525 * Fixed a fatal bug in private message sending and reception
2526 encryption and decryption when using private message keys.
2527 The implementation was incorrect and did not follow the
2528 specification. It causd that some of the message were
2529 lost since it did not use the sending and receiving keys
2530 as the protocol suggests. This has been fixed and will cause
2531 incompatibilities with older clients when sending private
2532 message encrypted with private message keys. Affected files
2533 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2534 and various other in Irssi SILC Client.
2536 Added `responder' boolean argument to the functions
2537 silc_client_add_private_message_key[_ske] to indicate when
2538 the key is added as responder or initiator of the key
2541 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Removed the silc_ske_check_version function and created
2544 a SilcSKECheckVersion callback. Added also a function
2545 silc_ske_set_callbacks that is now used to set all SKE
2546 callbacks. The callback functions are not given to
2547 the SKE functions anymore, but this function is used to
2550 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2552 * Added `silc_version' argument to the silc_client_alloc
2553 to define the version of the application for the library.
2554 The library will use the version string to compare it
2555 against the remote host's (usually a server) version
2556 string. Affected file lib/silcclient/silcapi.h
2558 * Added the KE protocol context to Key Agreement context
2559 in client library so that we can abort the SKE if it
2560 is in process when we get timeout. Affected file is
2561 lib/silcclient/client_keyagr.c.
2563 * Do not resolve the client ID forever if it returns in the
2564 first time that such client does not exist. This was done
2565 for example with private message. Affected file is
2566 lib/silcclient/client_prvmsg.c.
2568 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Do not add regex.h for WIN32. The affected file
2571 includes/silcincludes.h.
2573 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2574 not work yet 100%. It generates the DLL's automatically
2575 when compiling with --with-win32 under cygwin.
2577 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * lib/contrib/regex.c is not compiled on WIN32.
2581 * Added silc_net_get_socket_opt function to the
2582 lib/silcutil/silcnet.h.
2584 * Added includes/silcwin32.h for WIN32 specific includes
2587 * Do not use ptime structure or any of the posix process
2588 functions on WIN32 in lib/silccrypt/silrng.c.
2590 * Added silc_gettimeofday to provide generic function
2591 for struct timeval on all platforms. Added the function
2592 to lib/silcutil/silcutil.h.
2594 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2596 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2597 library as they clearly belong there. As a plus side we
2598 can make the actual socket connection routines platform
2601 Added also new generic function silc_socket_read and
2602 silc_socket_write (that used to be silc_packet_[read/write].
2603 The implementation of these are platform specific.
2605 * Added WIN32 specific routines of silc_socket_[read/write]
2606 to lib/silcutil/win32/silcwin32sockconn.c.
2608 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Added preliminary support for native WIN32 compilation under
2611 cygwin (using the -mno-cygwin option for GCC) to the
2612 ./configure.in.pre. The --with-win32 now prepares the
2613 compilation for native WIN32.
2615 * Rewrote the SILC Scheduler interface in the file
2616 lib/silcutil/silcschedule.h. The scheduler is now context
2617 based and does not have anymore any global static scheduler.
2618 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2619 and created lib/silcutil/win32 directory for WIN32 based
2622 * Added Unix specific network routines to the
2623 lib/silcutil/unix/silcunixnet.c and the old
2624 lib/silcutil/silcnet.c includes now only generic routines.
2626 Added WIN32 specific network routines to the
2627 lib/silcutil/win32/silcwin32net.c.
2629 * Added Unix specific utility functions from the
2630 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2632 * Added WIN32 SILC Scheduler to the file
2633 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2636 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2638 * Do not handle JOIN notify in the server if the target client
2639 is not registered (idata->registered == FALSE). The affected
2640 file is silcd/packet_receive.c.
2642 * Update the nickrec->founder in event_cumode in the Irssi SILC
2643 client. Affected file irssi/src/silc/core/silc-channels.c.
2645 * Fixed the CUMODE_CHANGE notify handling in the server when
2646 server and router are announcing their clients on channels.
2647 Now the mode changes are saved and notified correctly. The
2648 affected file is /silcd/packet_receive.c.
2650 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2651 They really did not replace the cache entry in the ID Cache.
2652 Now they do that. Affected file silcd/idlist.c.
2654 * Fixed the KICK notify handling in the Irssi SILC client to
2655 update the channel records so that the kicked client does not
2656 appear to be on the channel. The affected file is
2657 irssi/src/silc/core/silc-channels.c.
2659 * Always update the conn->current_channel when executing command
2660 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2662 * Fixed the KILL notify handling in Irssi SILC client to remove
2663 the killed client on all channels.
2665 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Fixed the silc_parse_command_line to remove extra spaces
2668 from the start and end of the arguments. Affected file is
2669 lib/silcutil/silcutil.c.
2671 * Cancel and free any active protocol in the function
2672 silc_server_close_connection. Affected file silcd/server.c.
2674 * Cancel and free any active protocol in the function
2675 silc_client_close_connction. Affected file is
2676 lib/silcclient/client.c.
2678 * Do not execute the KILL command for clients that are in
2679 history (ie. they are not in the network). Affected file is
2682 * Fixed KILL notify handling, client does not crash anymore.
2683 Affected file irssi/src/silc/core/silc-channels.c.
2685 * Reduced the default packet buffer size from 2048 to 1024 in
2686 lib/silccore/silcpacket.c.
2688 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2689 counter to the SKE context that is incresed when the SKE library
2690 performs async operation outside the library. If the outside
2691 process frees the SKE context and FREED status will be set
2692 and the library will detect after the sync operation that the
2693 libary is freed. The affected files are
2694 lib/silcske/silcske[_status].[ch].
2696 * Resolve the client entry information in the function
2697 silc_client_channel_message to assure that NULL pointer is not
2698 passed as client entry to the application. */
2700 * Fixed the task timeout calculation to assure that there is
2701 never negative timeouts. The affected file is
2702 lib/silcutil/silcschedule.c.
2704 * Fixed the channel user mode notification sending in server.
2705 It was sent point-to-point to the router (or to server by router)
2706 but it needs to be destined to a channel. The routines now
2707 supports sending the channel user mode notifys to the channels
2708 when announcing clients and channels. Affected files are
2709 silcd/server.c and silcd/packet_receive.c.
2711 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2712 It did not actually replace the old channel entry in the cache.
2713 Affected file lib/silcclient/client_notify.c.
2715 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Fixed a possible crash in silc_packet_send_prepare. It now
2718 assures always that there is enough space in the buffer and
2719 at the tail area of the buffer (for MAC).
2721 Fixed the inbound buffer reallocation in silc_packet_read.
2722 It was old code and did not handle the reallocation correctly.
2725 The affected file is lib/silccore/silcpacket.c.
2727 * Fixed buffer overflow in silc_parse_nickname in the file
2728 lib/silcutil/silcutil.c.
2730 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * make install generates new server keys only if there is not
2735 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2738 Added check that if the NOREPLY is set then we will not send
2739 the away message. This avoids infinite loop of away messages
2740 if both clients are away. The affected file is
2741 lib/silcclient/client_prvmsg.c.
2743 * Fixed client crash if /NICK was given without arguments.
2744 Affected file lib/silcclient/command.c.
2746 * Server does not send the invite list in INVITE command back
2747 to the client if the list was not altered. Added this notion
2748 to the protocol spec as well. Affected file silcd/command.c.
2750 Fixed possible crash in INVITE command by checking the
2751 value of silc_server_get_client_route command.
2753 * Fixed the INVITE notify type handling. The arguments are now
2754 taken in correct order and client does not crash. The affected
2755 file is irssi/src/silc/core/silc-channels.c.
2757 Removed the "Inviting xxx to channel" message from the
2758 client library away and let the application handle it.
2759 Affected file lib/silcclient/command.c. Added that message
2760 to Irssi SILC client's message formats.
2762 * Fixed CMODE command crash in client. It now checks the
2763 amount of arguments correctly and does not crash. The affected
2764 file is lib/silcclient/command.c.
2766 * Do not create new channel automatically in silc_channels_join
2767 but check whether the channel by that name already exists.
2768 Affected file irssi/silc/core/silc-channels.c.
2770 * Do not send the SERVER_SIGNOFF to router if the disconnected
2771 entity was the router. Affected file silcd/server.c.
2773 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2774 SILC client as it was missing from there.
2776 Added the handling of the KICK notify to the Irssi SILC client
2777 as it was missing. Added "you have been kicked" message to
2778 Irssi SILC client's message modules formats.
2780 Added the handing of the KILL notify to the Irssi SILC client
2781 as it was missing. Added the kill message module formats
2784 The affected file is irssi/src/silc/core/silc-channels.c.
2786 * The router did not save the channel mode the server announced.
2787 Affected file silcd/packet_receive.c.
2789 * Fixed a possible crash in INFO command in server. If the
2790 server did not provide the server info it crashed. Affected
2791 file silcd/command.c.
2793 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2795 * Fixed the GETKEY command in the server to check also the
2796 global list. Otherwise the GETKEY would not work correctly
2797 in normal SILC server. Affected file silcd/command.c.
2799 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Fixed GETKEY crash, it crashed if the command did not succseed.
2803 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2805 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2806 is now real and not just an macro interface to GMP.
2808 Removed the entire GMP from the source tree and imported new
2809 NSS MPI library instead. Reason for removing GMP is that it is
2810 extremely large and compiles extremely slow. The NSS MPI
2811 is only a few files and compiles in less than 10 seconds.
2812 The speed is also about the same as GMP. The MPI is imported
2813 to lib/silcmath/mpi.
2815 If the system has GMP installed we will still use the GMP.
2816 If it is not then the NSS MPI will be compiled.
2818 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2820 * Merged a long nickname (127 characters long) crash bugfix from
2821 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2823 * Merged a freed memory reference bugfix from Irssi CVS tree.
2824 Affected file irssi/src/core/commands.c.
2826 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2828 * Added the server's public key sving and verification to the
2829 server when performing the SKE. This was missing and the
2830 remote server's (or router's) public key was accepted without
2831 checking whether we have it previously or trust it at all.
2832 Affected file silcd/protocol.c.
2834 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Check in the silc_server_timeout_remote if protocol is active
2837 and make sure that the protocol's final callback is called so
2838 that all memory if freed. Affected file silcd/server.c.
2840 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * silc_server_whois_send_reply crashed the server if the nickname
2843 was 127 characters long. Affected file silcd/command.c.
2845 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Added sanity check to the silc_server_new_client. If the hostname
2848 is provided inside username then check that the provided hostname
2849 really is the same as the resolved one. If the hostname was not
2850 resolved then check it from the public key. Affected file is
2851 silcd/packet_receive.c.
2853 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2854 if the server disconnected us and the connection is not valid
2855 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2857 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2858 the library to the lib/silcutil/silcutil.[ch].
2860 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Close log file after open. Affected file
2863 lib/silcutil/silclog.c.
2865 * Check whether sock == NULL in silc_client_send_packet and return
2866 if it is. Affected file lib/silcclient/silcclient.c.
2868 * Check rec->entry == NULL in the Irssi SILC Client before
2869 sending the channel message. Affecte file is
2870 irssi/src/silc/core/silc-servers.c.
2872 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Merged a splitted window bugfix from Irssi CVS tree. The
2875 affected file is irssi/src/fe-text/textbuffer-view.c.
2877 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2878 It did not print nickname.
2880 * Improved the distributions system a bit.
2882 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2885 irssi/src/fe-text/gui-window.c.
2887 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2888 to in-active server. The affected file is
2889 irssi/src/silc/core/client_ops.c.
2891 * Resolve the client in USERS command reply if the entry does
2892 not have username resolved. The affected file is
2893 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2894 command to WHOIS command to really resolve stuff. The USERS
2895 is not used any more in any critical section so WHOIS can
2896 be used even though it might be slower than IDENTIFY.
2898 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2901 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2903 * Changed the protocol API a bit more consistent in the
2904 lib/silccore/silcprotocol.[ch].
2906 * Changed the following headers to ROBODoc format:
2908 lib/silccore/silcpayload.h
2909 lib/silccore/silcprotocol.h
2910 lib/silccore/silcsockconn.h
2912 All core library headers are now formatted.
2914 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Fixed a bug in Irssi SILC client; do not show that you are
2917 server/router operator if you really are not. Affected file is
2918 irssi/src/silc/core/client_ops.c.
2920 * Renamed silc_command_free_payload to silc_command_payload_free.
2921 Affected file lib/silccore/silccommand.h
2923 * Added silcmath.h to include the prototoypes of various routines
2924 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2927 * Changed the following headers to ROBODoc format:
2929 lib/silccore/silcchannel.h
2930 lib/silccore/silccommand.h
2931 lib/silccore/silcid.h
2932 lib/silccore/silcidcache.h
2933 lib/silccore/silcmode.h
2934 lib/silccore/silcnotify.h
2935 lib/silccore/silcpacket.h
2936 lib/silcmath/silcmath.h
2938 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Added checking to the server code not to start the server if
2941 ciphers and stuff are not configured properly. Affected files
2942 silcd/serverconfig.[h] and silcd/server.c.
2944 * Changed the layout of the header files of the public interfaces
2945 in the SILC libraries. The new layout supports ROBODoc
2946 documentation tool (and some others) so that it is easy to create
2947 a library reference manual. All the other headers and source
2948 code must still follow the CodingStyle document. Also source
2949 code must not include these ROBODoc stuffs, only the headers.
2950 Furthermore, all public interface headers must now be named
2951 by using `silc' prefix, example: silcapi.h, silccipher.h.
2952 Some files were renamed due to this. All the other headers
2953 must not be used as public interfaces. I will update the
2954 CodingStyle document later. Changed following headers, so far:
2956 lib/silcclient/silcapi.h
2957 lib/silccore/silcauth.h
2958 lib/silccore/silcprivate.h
2959 lib/silccrypt/silcdh.h
2961 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Removed silc_client_packet_send_flush from the client library
2966 as it is not needed. Affected file lib/silcclient/client.[ch].
2968 * Added printing of message of unresolved authentication method
2969 to the Irssi SILC client. Added it to the module formats.
2970 Removed the same message from the client library.
2972 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Added new distribution feature, DISTLABEL. Every distribution
2975 can define own preprocessor label that can be used in the
2976 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2977 file distributions, acconfig.h.pre and prepare.
2979 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added Makefile.defines_int to include the actual definitions
2982 for Makefile.defines.in. Tested the new distribution system,
2983 created distributions and tested installation.
2985 * Added AWAY message printing to the Irssi SILC client. Added
2986 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2988 * Added SCONNECT command to call the SILC's CONNECT command.
2989 Cannot use CONNECT directly since Irssi uses that internally.
2990 Affected file irssi/src/silc/core/silc-servers.c.
2992 Added ACTION local command. It is same as ME command but takes
2993 the channel as mandatory argument.
2995 Rewrote some of the Irssi's help files to suite for SILC
2998 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3000 * Added Makefile.defines[.in] that should for now on be included
3001 in all Makefile.am file in the source tree. That file includes
3002 all common compilation definitions for SILC source tree.
3004 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Minor changes to the ./prepare script to change the package
3007 name according the distribution name to the configure.in.
3009 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Created new distribution system. Added file `distributions'
3012 that defines all the distributions that can be created out of
3013 the SILC source tree. The ./prepare script now reads that
3014 file to determine how to prepare the distributions. The
3015 first argument to the ./prepare is the name of the distribution
3016 and second is the version of the distribution. If given
3017 without arguments it creates the default (toolkit) distribution
3018 with the default version (defined in ./prepare).
3020 All Makefile.am files that are subject to the distributions
3021 are now named as Makefile.am.pre. These are ./Makefile.am
3022 and lib/Makefile.am. Others may be changed later.
3024 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Added invite list, ban list, some key management and connection
3027 error message printing to module formats in the Irssi SILC client.
3029 * Added new silc_client_set_away_message to set the away message
3030 that is back to the person who sent private message. The
3031 affected file lib/silcclient/silcapi.h and the
3032 lib/silcclient/client_prvmsg.c.
3034 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Fixed the private message sending in the Irssi SILC client,
3037 added local command KEY to the Irssi SILC client.
3039 Added key management and key agreement message formats to the
3040 irssi/src/fe-common/silc/module-formats.[ch].
3042 Added USERS (alias WHO) printing, server/router operator
3043 indication and LIST command printing to the module formats.
3045 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Fixed channel joining notify handling, cumode notify handling
3048 from Irssi SILC client.
3050 * Added SILC specific module-formats to the Irssi SILC client so
3051 that SILC specific message hilighting, colors etc is possible.
3052 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3054 Added channel mode, channel user mode, actions, notices,
3055 whois and whowas printing to the the module-formats.c.
3057 * Fixed a bug in channel deletion in the server. The channel
3058 is not left to the cache even if the channel founder auth mode
3059 is set when there are no users anymore on the channel. Affected
3060 file silcd/server.c.
3062 * The silc_net_localhost now resolves the entire hostname including
3063 the domain name. Affected file lib/silcutil/silcnet.c.
3065 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Changed the ask_passphrase client operation to be ascynchronous.
3068 It has now a completion callback and a context that the
3069 application must call after it has got the passphrase from
3070 the user. Affected files lib/silcclient/silcapi.h,
3071 lib/silcclient/protocol.c, lib/silcclient/command.c and
3074 Added SilcAskPassphrase callback that the application calls
3075 to deliver the passphrase to the library.
3077 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3078 The public key verification and especially a certificate
3079 verification is asynchronous procedure.
3081 Added new SILC_SKE_STATUS_PENDING status to indicate the
3082 request is pending and a callback will be called to finalize
3085 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3086 indicate that remote end did not send its public key (or
3087 certificate), even though we require it. Added check for this
3088 condition in the SKE. This was a security bug, now fixed.
3090 Defined new SilcSKEVerifyCbCompletion callback that is called
3091 when the verification process is completed.
3093 The affected files lib/silcske/silcske_status.h and
3094 lib/silcske/silcske.[ch].
3096 * Changed the verify_public_key client operation to be async
3097 as well. Defined SilcVerifyPublicKey callback that is used to
3098 indicate the success of the public key verification process.
3100 Changed the server and client to use the new async client
3103 * Changed the Irssi SILC client's internal scheduler to be called
3104 twice as many times as it used to be. As a result the client
3105 should be a bit faster now. Affected file is
3106 irssi/src/silc/core/silc-core.c.
3108 * Added support to Irssi SILC client of asynchronous public key
3109 verification and passphrase inquiry. Affected file is
3110 irssi/src/silc/core/silc-core.c.
3112 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Do not say "You have left channel %s" in client library.
3115 Moved it to the application. Affected files are
3116 lib/silcclient/command.c and silc/client_ops.c.
3118 * Fixed silc_client_get_clients. Command context was not
3119 duplicated and was freed memory in the callback. Affected
3120 file lib/silcclient/idlist.c.
3122 * Do not say "you are now talking..." on JOIN command in the
3123 client library. The appliation must handle it.
3125 * Do not say ".. changed topic to" in command reply in the
3126 client libary. The application must handle it.
3128 * Fixed TOPIC command sending in the client library.
3130 * Fixed a memory leak in silc_client_command_free in the file
3131 lib/silcclient/command.c.
3133 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Imported a modified version of Irssi client to the source tree.
3136 The Irssi will be used to create a new client called
3137 Irssi SILC. Imported to irssi/.
3139 Added silc_core_init_finish function to the Irssi. Affected
3140 file irssi/configure.in.
3142 A lot changes in the Makefile.ams around the irssi tree.
3144 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Do not rehash if the new size is same as the old size of the
3147 hash table, in the silc_hash_table_rehash*. The affected file
3148 lib/silcutil/silchashtable.c.
3150 * Replaced hash_table_del_by_context calls from the server
3151 (when channel->user_list and client->channels) to the
3152 hash_table_del as it is sufficient and faster.
3154 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Added silc_hash_table_list, silc_hash_table_get and the
3157 SilcHashTableList structure to provide an alternative way to
3158 traverse the hash table. The affected files are
3159 lib/silcutil/silchashtable.[ch].
3161 * Changed the server's idlist routines to use the hash table
3162 routines to optimize the code.
3164 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Replaced the client entry's `channel' list and channel entry's
3167 `user_list' list to hash tables for optimized lookup. Changed
3168 the code to use the hash table interface around the code.
3169 Affected file lib/silcd/idlist.[ch].
3171 * Added `auto_rehash' boolean argument to the function
3172 silc_hash_table_alloc to indicate whether the hash table should
3173 auto-rehash when it thinks is appropriate time. It will
3174 increase the hash table size if the there is twice as much
3175 entries in the table than the size of the table, and will
3176 decrease the size if there are twice as less entries than
3177 the size of the table.
3179 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3183 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * silc_idcache_purge_by_context deletes the entry now by context
3186 as it is supposed to do. Affected file lib/silccore/idcache.c.
3188 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3189 client is not anymore valid (WHOWAS givens the info) and not
3190 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3192 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3194 * Removed the `data' and `data_len' arguments from the ID Cache
3195 interfaces and added `name' argument. ID Cache does not handle
3196 anymore the binary data only a names associated with given ID.
3198 * When hashing a Client ID with silc_hash_id the entire ID is
3199 not hashed anymore, instead only the hash of the Client ID is
3200 hashed. This way we can access the Client ID from the cache
3201 with Client ID but with the hash of the ID (which is a hash of
3202 the nickname) as well without any difference in performance.
3204 Added also silc_idcache_find_by_id_one_ext to do one on one
3205 searching when we have the actual ID. Added also function
3206 silc_hash_client_id_compare. The affected files are
3207 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3209 * When hashing the name associated with a ID it is always done
3210 in lowercase. This way we can access the cache without worrying
3211 about case-sensitivity, even though, for example nicknames are
3214 * Fixed a bug in server with channel message sending. It put
3215 wrong ID type as destination ID. The affected file
3216 silcd/packet_send.c.
3218 * silc_idcache_del_by_context now deletes from all hash tables
3219 by context. Affected file lib/silccore/idcache.c.
3221 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Changed the client library to use the new ID Cache interface.
3224 Changes around the source tree.
3226 * Added silc_hash_table_rehash_ext to rehash with specific
3227 hash function. Affected file lib/silcutil/silchashtable.[ch].
3229 * Added silc_hash_string_compare to compare two strings in the
3230 hash table. Affected file lib/silcutil/silcutil.[ch].
3232 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Added new function silc_idcache_del_by_context into the
3235 lib/silccore/idcache.[ch].
3237 * Changed the server's ID list routines to use the new ID Cache
3238 interface. Changes around the source tree.
3240 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Added silc_hash_table_del[_by_context]_ext functions in to the
3243 lib/silcutil/silchashtable.[ch].
3245 Removed silc_hash_table_find_all* routines and added new
3246 silc_hash_table_find_foreach to replace them.
3248 Added silc_hash_table_replace_ext function as extended
3249 replacing function. Separated the simple hash table interface
3250 from the extended hash table interface in the file
3251 lib/silcutil/silchashtable.h.
3253 * Fixed minor bugs and changed it to use some of the new
3254 hash table functions in lib/silccore/idcache.c
3256 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added new function silc_hash_table_find_all to return all keys
3259 in the hash table by the specified key. As the hash table is
3260 collision resistant it also makes it possible to have several
3261 duplicate keys in the hash table. This function may be used to
3262 find all of the keys from the hash.
3264 Added user_context arguments to the SilcHashFunction,
3265 SilcHashCompare and SilcHashDestructor to deliver user specified
3268 Added new fuctions silc_hash_table_find[_all]_ext to do
3269 extended lookup with specified hash and compare functions and
3270 specified user contexts.
3272 Added new function silc_hash_table_add_ext to add the key
3273 with specified hash function and user context.
3275 Added new function silc_hash_table_foreach to traverse all
3276 entrys in the hash table. Added SilcHashForeach callback
3279 Added new function silc_hash_table_del_by_context to delete
3280 the entry only if the context associated with the key matches.
3282 Affected files are lib/silcutil/silchashtable.[ch].
3284 * Removed silc_hash_[server/client/channel]_id and added just
3285 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3286 silc_hash_id_compare to compare two ID's using as the hash table
3287 comparison function. Added also silc_hash_data to hash
3288 binary data and silc_hash_data_compare to compare it.
3290 * Removed silc_idlist_find_client_by_hash as it is not needed
3291 anymore. Affected file silcd/idlist.[ch].
3293 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3294 to use internally the SilcHashTable. The new ID Cache is a lot
3295 faster than the old one. Some of the ID Cache interface was also
3296 rewritten and obsolete and stupid functions were removed.
3298 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Added entry_count field to the SilcHashTable to keep the number
3301 of the entries in the table. Implemented the function
3302 silc_hash_table_rehash. Added new function
3303 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3305 Fixed a minor bug in silc_hash_table_free.
3307 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3308 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3309 into the lib/silcutil/silcutil.[ch].
3311 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Implemented a collision resistant hash table into the
3314 lib/silcutil/silchashtable[ch]. See the header and the source
3315 for the SilcHashTable API.
3317 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Merged dotconf version 1.0.2 into lib/dotconf.
3321 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Do not compile anything in lib/silcsim/* if the SIM support
3324 is not enabled. The tree should now compile without problems
3327 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Compiled the SILC under cygwin. Compiled and tested briefly
3330 without problems. More tests needed. The SIMs didn't compile
3333 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3335 * Fixed possible crash in silc_get_username in the
3336 lib/silcutil/silcutil.c.
3338 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Fixed a va_arg in silc/client_ops.c.
3342 * Oops, RC5 routines were named AES and caused some problems
3343 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3345 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Added new SilcIDIP structure into the lib/silccore/id.h and
3348 replaced the old `ip' fields from all SILC ID's to that type.
3349 This is a step towards IPv6 support.
3351 The silc_id_get_len takes now the ID as an extra argument.
3352 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3353 both IPv4 and IPv6 based ID's.
3355 The affected files are lib/silccore/id.[ch] and other files
3356 around the tree using these routines.
3358 * Removed the ID length arguments in server from various
3359 silc_server_send_notify_* routines -> they are not needed
3362 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Fixed memory leak in silc_encode_pem_file in the file
3365 lib/silcutil/silcutil.c.
3367 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Check minor version as well in the SKE. Affected files are
3370 silcd/protocol.c and lib/silcclient/protocol.c.
3372 * Added --identifier option to the server so that an identifier
3373 can be when creating the public key for the server. Affected
3374 file is silcd/silcd.c.
3376 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3377 lib/silccrypt/silcpkcs.c.
3379 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Register default ciphers and stuff when using -C option with
3382 the server. Affected file sildc/silcd.c.
3384 * Put back the servers public key filename format, it is better
3385 than the new one. For now, the client keys are saved with the
3386 new filename format. The affected file silc/client_ops.c.
3388 * Implemented the Cipher API for the rest of the ciphers that
3389 did not implement it or implemented it the wrong way.
3391 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Register default ciphers and stuff when using the -S option
3394 in the client. Affected file silc/silc.c. Same also when
3395 creating new key pair with -C option.
3397 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Fixed the silc_verify_public_key client operation function to
3400 save the public keys differently. The fingerprint is now
3401 used as filename and not the hostname. This way also the
3402 client keys are saved uniquely and not with hostnames. The
3403 affected file is silc/client_ops.c.
3405 * Trimmed the silc_hash_fingerprint function to remove extra
3406 whitespaces from the end of the fingerprint. The affected
3407 file is lib/silccrypt/silchash.c.
3411 * Added silc_cipher_register_default function to register all
3412 default ciphers. It can be used when configuration files
3413 does not exist and the application does not want any specific
3414 ciphers in any specific order.
3416 The SilcDList is now used as silc_cipher_list dynamically
3417 allocated cipher list. Removed the static list all together
3418 and now all ciphers must be allocated to the dynamic list.
3419 The silc_cipher_alloc routine was changed to check only the
3422 All silc_cipher_* routines that used to return int returns
3425 The affected files lib/silccrypt/silccrypt.[ch].
3427 * The same thing was done to silc_hash_* as for silc_cipher_*
3428 routines. Affected files lib/silccrypt/silchash.[ch].
3430 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3431 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3432 Added also silc_pkcs_[un]register[_default] functions.
3433 Removed the data_context from the PKCS API.
3435 * Added silc_hmac_register_default function to register default
3436 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3437 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3438 to unregister all hmacs at once.
3440 * Register the default ciphers, hash functions, PKCSs and HMACs
3441 if client's configuration file does not exist. The affected
3444 * The client did not load the hash functions from the SIM
3445 modules at all. Added support for this. Affected file is
3446 silc/clientconfig.c.
3448 * When decoding public key with silc_pkcs_public_key_decode, check
3449 the supported algorithm only if PKCS are registered. Affected
3450 file lib/silccrypt/silcpkcs.c. The same was done with the
3451 silc_pkcs_private_key_decode.
3453 * Fixed the SILC List routines to keep the list always in order.
3454 It used to change the list's order when traversing the list but
3455 not it preserves the order. Affected file lib/trq/silclist.h.
3457 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Added the client library to use the SilcSocketConnection's
3460 reference counter (by silc_socket_dup) to prevent the bug that
3461 the socket object may be freed underneath async operation.
3463 * The name resolv library checking fixes in the configure.in.pre.
3466 * Created new version of the protocol drafts for future
3467 development. The -03 drafts are the ones that will be changed
3468 in the trunk now and the -02 will remain as they are.
3470 * Send list of CUMODE notifys to the router when announcing
3471 the channel users to the router. Affected file silcd/server.c.
3472 If the router receiving channel founder CUMODE for a channel
3473 that already has channel founder it will send CUMODE notify
3474 to the sender to remove the channel founder rights from the
3475 announced client. Affected file silcd/packet_receive.c.
3477 * The CUMODE notify may now use Server ID as well as the entity
3478 who changes the mode. Updated protocool specs.
3480 * Updated INSTALL and README files.
3482 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * New web pages in the http://silc.pspt.fi. The pages was
3489 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Implemented the [DenyConnectin] config section in the server.
3492 Added silc_server_config_denied_conn to check whether incoming
3493 connection is denied. Affected file silcd/serverconfig.[ch].
3495 * Do not check the ports when checking the incoming configuration
3496 data if the port is 0, meaning any. Affected file is
3497 silcd/serverconfig.c.
3499 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Fixed buffer overflow in silc_string_compare in the file
3502 lib/silcutil/silcutil.c.
3504 * Fixed double free in silc_server_command_leave in the file
3507 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3509 * Fixed the version checking in the server. Affected file is
3512 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Fixed the configuration data fetching when accepting new
3515 connections in the server. Affected file silcd/server.c.
3517 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Added `sender_entry' argument to the function
3520 silc_server_packet_relay_to_channel so that we can check
3521 whether some destination actually belongs to the same route
3522 the sender belongs (ie, we must not resend the packet to the
3523 sender). Affected file silcd/packet_send.[ch].
3525 * Added `servername' field to the SilcClientEntry in the server
3526 to hold the name of the server where client is from. Affected
3527 file is silcd/idlist.h.
3529 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Moved the channel message encrypting in the router betwen
3532 router connections from silc_server_channel_message to the
3533 silc_server_packet_relay_to_channel since we want to check
3534 whether we have anybody channel before encrypting anything.
3535 Affected files silcd/packet_[receive/send].c.
3537 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Fixed the [AdminConnection] server config section to support
3540 multiple entries. Affected file silcd/serverconfig.c.
3542 * Added support into the server to check the validity of the
3543 incoming connection before executing any KE or authentication
3546 * The connection configuration is now saved to the KE and
3547 connection auth protocol contexts and not fetched anymore in
3548 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3550 * The local hosts listenning address and port is also resolved
3551 now when starting the server. We want to have the socket object
3552 to include the real address and port for the listener. Added
3553 new function silc_net_check_local_by_sock into the files
3554 lib/silcutil/silcnet.[ch].
3556 * Fixed a broadcast bug in server -> do not broadcast if we
3559 * Fixed a routing bug. Do not route broadcast packets ever.
3560 Broadcast packets must be processed always and not routed since
3561 they may be destined to some other host than yourself and thus
3562 would get routed without no good reason. Affected file is
3565 * Added function silc_server_config_is_primary_route to check
3566 whether primary router connection has been configured (a router
3567 configuration that we are initiating). If there is not, we
3568 will assume that there is only two routers in the SILC network
3569 and we will use the incoming router connection as our primary
3570 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3572 * Changed the order of the broadcasting. Broadcast _after_ the
3573 packet has been processed not before. Affected file is
3576 * Fixed a [ClientConnection] parsing bug. The port was never
3577 parsed correctly thus resulting to port 0. Affected file
3578 silcd/serverconfig.c.
3580 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3581 argument and did not set the broadcast packet flag. Affected
3582 file silcd/packet_send.c. Fixed same bug in the function
3583 silc_server_send_notify as well.
3585 * If we receive NEW_ID packet for our own ID in the server, ignore
3588 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Removed the nickname from the Private Message Payload.
3593 Updated the code and the protocol specs.
3595 * Updated protocol specs for submitting to the IETF.
3597 * Tweaked the Random Number Generator a bit. Affected file
3598 lib/silccrypt/silcrng.c. Exported a new function
3599 silc_rng_[global]_add_noise which can be used to add more
3602 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Do not parse packets with different timeout when protocol
3605 is active -> may cause problem with rekey. Affected file
3608 * When server receives signoff notify it must not create
3609 new channel key if the client is on any channels since the
3610 sender of the signoff notify will create it.
3612 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added printing of error messages during SKE protocol from the
3615 failure packet sent by server during SKE. Affected file
3618 * Removed the client's failure_callback handling with timeout
3619 and handle it immediately when received.
3621 * The SKE library returned wrong type in SUCCESS and FAILURE
3622 packets. They must be 32 bit MSB not 16 bit MSB.
3624 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Ok, rewrote the logic of the re-key and now it seems to work.
3627 I tested it on high traffic with frequent re-keys without
3628 problems. Added hmac_receive (and renamed hmac to hmac_send)
3629 in SilcClientConnection in lib/silcclient/client.h and
3630 in SilcIDListData in silcd/idlist.h. Also, removed the
3631 SilcPacketParserContext's cipher and hmac fields as they are
3632 not needed anymore and actually caused some problems when
3633 the ciphers and hmac's changed underneath the packet parser.
3635 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * If re-key protocol is active then process the incoming packets
3638 synchronously since we must assure that icoming packets encrypted
3639 with the old key is processed before the new keys is set to
3640 use. This is true other packets than for REKEY packets.
3641 Affected file silcd/server.c. The same was done to client library
3642 as well, affected file lib/silcclient/client.c.
3644 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * Fixed bug in client and server to accept the force send if
3647 the packet is send from silc_[server/client]_packet_process
3648 function. Otherwise the packets are never delivered, oops.
3650 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Disable force sending of packets when REKEY protocol is active.
3653 We must assure that no packet is sent directly when rekey is
3654 performed. All packets must be sent through packet queue.
3655 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3656 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3657 function is silc_[server/client]_packet_send_real to check
3660 * Replaced the SIM paths from example config files to
3661 /usr/local/modules. Also, make install creates now
3662 /usr/local/silc/logs directory to hold all the SILC server
3665 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Made the configure.in.pre work on Solaris. Patch by salo.
3669 * Made all ciphers compatible with non-x86 machines. Defined
3670 CBC mode macros into lib/silccrypt/ciphers_def.h.
3672 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Fixed the make install.
3676 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * When MAC computation fails the silc_packet_decrypt returned 0
3679 even though it was supposed to return -1. Fixed this. The
3680 affected file is lib/silccore/silcpacket.c.
3682 * Do not replace the config files in /etc/silc (in make install)
3683 if they already exist. Affected file ./Makefile.am.
3685 * Do not send re-key packets immediately but through packet queue.
3686 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3688 * Changed silc_net_check_host_by_sock to return FALSE if the
3689 IP/DNS could not be resolved. Though, it returns the IP address
3690 now even if it could not resolve it (but returns also FALSE).
3691 Affected file lib/silcutil/silcnet.[ch].
3693 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Added silc_pkcs_decode_identifier to decode the public key's
3696 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3697 Added also silc_pkcs_free_identifier. Added also new context
3698 SilcPublicKeyIdentifier.
3700 * Added -S option to the silc client. It is used to dump the
3701 contents of the specified public key file.
3703 * Changed the PKCS api to return the public key length when
3704 setting the public key.
3706 * Fixed a fatal bug in the public and private key file loading.
3707 Affected file lib/silccrypt/silcpkcs.c.
3709 * Execute the packet parsing for client with zero (0) timeout
3710 if the protocol is active. Affected file silcd/server.c.
3712 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Made the key generation options to the silcd program. Added
3715 -C option, equivalent to client's option.
3717 * Added new [ServerKeys] config section to the server. It
3718 configures the server's public and private key.
3720 * Defined generic Public Key Payload into the protocol
3721 specification to send specific type of public keys and
3724 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3725 public key or certificate.
3727 * Implemented the GETKEY command to the server and to the
3728 client library and on user interface.

3736 * Added SilcServerRekey context into silcd/idlist.h.
3738 * Added the PFS support as defined in the specification to the
3739 SKE protocol. Affected files lib/silcske/*.c.
3741 * Added `ske_group' field to the SilcServerRekey context to hold
3742 the number of the SKE group that is used with PFS in re-key.
3743 Affected file silcd/idlist.h.
3745 * Added PFS re-key support to the server. Affected file is
3748 * Added silc_protocol_cancel to cancel execution of the next
3749 state of the protocol. Affected file is
3750 lib/silccore/silcprotocol.[ch].
3752 * Added the re-key support with and without PFS to the client
3753 library. Re-key is performed once in an hour, by default.
3755 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3756 Added silc_client_rekey_callback and silc_client_rekey_final.
3757 Affected files are lib/silcclient/protocol.[ch] and
3758 lib/silcclient/client.[ch].
3760 * Removed the `hmac_key' and `hmac_key_len' fields from the
3761 SilcClientConnection structure; not needed. Affected file is
3762 lib/silcclient/client.h.
3766 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Do not ask whether user wants to use the negotiated private key
3769 for private messages, just use it. Affected file is
3770 silc/local_command.c.
3772 * Added `send_enc_key' and `enc_key_len' fields to the
3773 SilcIDListData structure since they are needed in the re-key
3774 phase. Affected file is silcd/idlist.[ch].
3776 * Implemented the simple re-key protocol into the server.
3777 Affected files silcd/server.c and silcd/protocol.[ch]. The
3778 re-key will be performed once in an hour, by default.
3780 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3781 Added silc_server_rekey, silc_server_rekey_callback and
3782 silc_server_rekey_final.
3784 * Removed Tunneled flag from the protocol. Updated the code
3785 and the specifications.
3787 * Adde `pfs' field to the SilcIDListData to indicate whether
3788 the PFS is to be performed in the re-key. Affected file is
3791 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3793 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3794 int64 of at least the xintXX size. If void * is less that 4
3795 bytes uint32 * will be used. Defined bool as boolean.
3797 * Changed _ALL_ unsigned long and unsigned int to uint32,
3798 unsgined short to uint16 in the source tree.
3800 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3801 not handle clients that has entry->data.registered == FALSE.
3802 They are not in the network anymore. Affected file is
3805 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Implemented the sending of the SERVER_SIGNOFF notify in the
3808 server. Affected file is silcd/server.c.
3810 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3811 Added also silc_notify_payload_encode_args into the
3812 lib/silccore/silcnotify.[ch].
3814 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3815 Affected file silcd/packet_receive.c.
3817 * Implemented the SERVER_SIGNOFF notify handling in the client
3818 library. Affected file lib/silcclient/client_notify.c. Also,
3819 implemnted the printing of the SERVER_SIGNOFF info to the
3820 application. Affected file silc/client_ops.c.
3822 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3823 if the deleting was successful. Affected file silcd/idlist.[ch].
3825 * Added support for public key authentication in the connection
3826 authentication protocol in the client library. Affected file
3827 lib/silcclient/protocol.c.
3829 * Changed the server's silc_idlist_get_clients_by_* interface
3830 to support already allocated array so that new entries may be
3831 added to pre-allocated array. Affected file silcd/idlist.[ch].
3832 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3833 and command replies.
3835 * All command reply functions in the server now calls the
3836 pending command callback even if error occured. This way the
3837 error will be delivered to the client as well. Affected files
3838 silcd/command.c and silcd/command_reply.c.
3840 * Fixed INFO command to return local server's info if no server
3841 was provided. Affected file lib/silcclient/command.c.
3843 * Removed RESTART command for good. Updated the code and the
3846 * Rewrote parts of the task system. It is a bit simpler now.
3847 Removed unsued task priorities. The affected files are
3848 lib/silcutil/silctask.[ch].
3850 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Moved the USERS printing from the library to the application.
3853 Affected files lib/silcclient/command.c and silc/client_ops.c.
3855 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Added channel key re-key support. The re-key is perfomed
3860 only by the router and is done once in an hour. Added `rekey'
3861 field to the SilcChannelEntry in the server. Affected files
3862 silcd/server.c and silcd/idlist.h.
3864 * Added silc_task_unregister_by_context into the file
3865 lib/silcutil/silctask.[ch].
3867 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Added SILC_UMODE_GONE mode to indicate when the client is not
3870 present in the SILC network. Added also support to the local
3871 command AWAY that will set this mode. Added support of showing
3872 "xxx is gone" in WHOIS command. The USERS command shows the
3873 gone status as well.
3875 * Fixed setting server and router operator privileges in the
3876 server's UMODE command. Affected file silcd/command.c.
3878 * Merged the SKE KE1 and KE2 payloads into one payload. The
3879 new KE payload is equivalent to the old KE2 payload.
3881 Cleaned up the SKE Start Payload parsing. It now uses the
3882 simple buffer unformatting to do the parsing. A lot faster
3885 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3886 to the SKE that is used to indicate whether both of the SKE
3887 parties should perform authentication. By default only the
3888 responder performs authentication. By setting this flag also
3889 the initiator must do authentication. By default it is unset
3890 since in normal SKE case, client to server connection, only
3891 the responder should do authentication. When doing SKE between
3892 two clients both should perform authentication. Updated the
3893 code and the protocol specs.
3895 * A little fix to IDENTIFY command in the server. Search the
3896 client first by hash not nickname. Affected file is
3899 * Fixed the silc_client_close_connection to support closing
3900 the client to client connections wihtout deleting too much
3901 data. Affected file lib/silcclient/client.c.
3903 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3904 are received if protocol used to be active but is not anymore
3905 the application would crash due to NULL pointer dereference.
3906 Affected files silcd/server.c and lib/silcclient/client.c.
3908 * Added `hash' field to the SilcClientConnection to include
3909 the hash function negotiated in the SKE protocol.
3911 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3912 to set the channel founder authentication data. A client can
3913 claim the founder rights later by providing the authentication
3914 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3915 This way the channel founder can regain the channel founder
3916 privileges even it is left the channel. This works only on
3917 local server and the client must be connected to the same
3918 server to be able to regain the founder rights. Updated the
3919 protocol specs accordingly.
3921 Added support to the CMODE command in the client to set the
3922 founder auth data. Read the README to see how to set it.
3924 Added support to the CUMODE command to claim the founder
3925 rights. Read the README to see how to do it.
3927 Added support for the founder authentication to the Channel
3928 Entry in the server. Affected file silcd/idlist.h.
3930 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3931 server's CMODE command. Affected file silcd/command.c.
3933 * Added the following new functions into lib/silccore/silcauth.[ch]:
3934 silc_auth_get_method and silc_auth_get_data.
3936 * The server now saves the remote hosts public key to the
3937 SilcIDListData pointer. Affected file silcd/protocol.c.
3939 * The normal server now does not remove the channel entry from
3940 the cache if the founder authentication data is set. It used
3941 to remove it if the founder was the last one on the channel on
3942 the server and left the channel. The auth data is saved and
3943 if the channel is re-joined later the old entry is used with
3944 the old auth data. Affected files silcd/command_reply.c and
3947 * Removed the `pkcs' field from the SilcIDListData structure
3948 in the server; it is not used. Affected file silcd/idlist.h.
3950 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Fixed packet processing on slow links. Partial packets were
3953 never re-processed because the incoming data buffer was cleared
3954 by the application. Application must not directly clear the
3955 sock->inbuf, the packet processing routines handle it. Fixed
3956 this in client library and in server.
3958 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Fixed the WHOIS and IDENTIFY send reply function to really
3961 check whether to send list or just one entry. Affected file
3964 * Cleaned up the LEAVE command's channel key distribution. The
3965 affected file silcd/command.c.
3967 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3968 can enforce the channel mode as well. In that case the ID
3969 includes the ID of the server. The code now enforces the
3970 mode change if the router have different mode than the server.
3972 * The notify client operation with CMODE_CHANGE notify can now
3973 return NULL client_entry pointer if the CMODE was not changed
3974 by client. Application must check for this.
3976 * Added <Server ID> argument to INFO command to support server
3977 info fetching by Server ID.
3979 * Added silc_server_announce_get_channel_users to get assembled
3980 packets of channel users of the specified channel. Affected
3981 file silcd/server.[ch].
3983 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3984 was freed underneath the ID Cache.
3986 * Re-announce clients when the server received CHANNEL_CHANGE
3987 notify from the router. Affected file silcd/packet_send.c.
3989 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3992 crashed since it did not handle the fact that there is no cipher
3993 called "3" and didn't check the error condition. Now fixed.
3995 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3996 flag. It can be used to send message requests.
3998 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Implemented the RESTART command in the client.
4002 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4003 notice type messages. Added notice printing to the user
4006 * The channel keys are not re-generated if the channel's mode
4007 is PRIVKEY, ie private key on the channel exists. Affected
4008 files silcd/server.c and silcd/command.c.
4010 * Fixed a little bug in channel message delivery when channel
4011 private keys are set in the server. Affected file is
4012 silcd/packet_send.c.
4014 * Changed the setting on channel->on_channel = TRUE from the
4015 silc_client_save_channel_key to the JOIN command reply. The
4016 key payload is not received if the private channel key is set.
4017 Affected file lib/silcclient/command_reply.c and the
4018 lib/silcclient/client_channel.c.
4020 * When the CMODE_CHANGE notify is sent and the channel private
4021 key mode is removed the channel key must be re-generated in
4022 other cells as well. Added this support for the router in the
4023 silcd/packet_receive.c.
4025 * Added new local command NOTICE to send notice message on
4026 channel. Affected file silc/local_command.[ch].
4028 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Added new local command ME to the client. It is used to send
4031 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4032 some action. Affected file silc/local_command.[ch].
4034 * Changed channel_message and private_message client operations
4035 to deliver the message flags to the application. Added also
4036 the `flags' arguments to the silc_client_send_channel_message
4037 and silc_client_send_private_message functions. Affected file
4040 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Redefined the Private Message Payload to support private message
4043 keys and to support the new private message flags. Updated
4044 the protocol specs. Flags makes it possible to have for example
4045 CTCP style messages.
4047 * Added new type SilcPrivateMessagePayload and defined an API
4048 for it in the lib/silcclient/silcprivate.[ch].
4050 * Tested private message private keys successfully. Tested the
4051 private message key set, unset and list commands with the new
4054 * Redefined the Channel Message Payload to include the channel
4055 message flags (equal with private message flags) to support
4056 for example CTCP style messages.
4058 * Defined some of the message (for channel and private message)
4059 flags. Updated the protocol specs and added the flags to the
4060 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4062 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Added SilcKeyAgreementStatus type to the key agreement routines
4065 to indicate the current status and error if one occured.
4066 The status types are defined in the lib/silcclient/silcapi.h.
4068 * Added new local command KEY that is used to set and unset private
4069 keys for channels, set and unset private keys for private messages
4070 with remote clients and to send key agreement requests and
4071 negotiate the key agreement protocol with remote client. The
4072 key agreement is supported only to negotiate private message keys,
4073 it currently cannot be used to negotiate private keys for channels,
4074 as it is not convenient for that purpose.
4076 * Fixed a minor pending callback setting bug in the function
4077 silc_client_get_client_by_id_resolve, now the function works.
4078 Affected file lib/silcclient/idlist.c.
4080 * Added function silc_net_get_local_port to get local bound
4081 port by socket. Added to lib/silcutil/silcnet.[ch].
4083 * Added `sockets' and `sockets_count' fields to the SilcClient
4084 object. They hold the sockets of the listenning sockets in
4085 the client. Listenning sockets may be for example the key
4086 agreement server. Affected file lib/silcclient/client.[ch].
4087 Added functions the silc_client_add_socket and the
4088 silc_client_del_socket. They are exported to the application
4091 * Added ~./silc/clientkeys to support other client's public keys.
4093 * Renamed verify_server_key client operation to verify_public_key
4094 and added one argument to indicate the type of the connection
4095 (server, client etc.).
4097 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Added silc_server_connection_auth_request to handle the
4100 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4101 silcd/packet_receive.[ch].
4103 * Added silc_server_send_connection_auth_request into the
4104 silcd/packet_send.c to send the connection auth request packet.
4106 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4109 * Fixed the public key authentication in responder side in the
4110 server. The `auth_data' pointer includes the SilcPublicKey
4111 not the path to the public key. Affected file silcd/protocol.c.
4113 * Implemented the public key authentication in the initiator side
4114 in the server. Affected file silcd/protocol.c.
4116 * Removed the [RedirectClient] config section from the server
4117 configuration. Is not needed and I don't want to implement it.
4119 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Cleaned up the CMODE command in the server. It now works
4122 correctly and supports all the modes defined in the protocol.
4123 Affected file is silcd/command.c.
4125 * Added `hmac_name' field to the SilcChannelEntry in the server
4126 to hold the default HMAC of the channel. It can be set when
4127 creating the channel (with JOIN command). Affected files
4130 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4131 type to indicate the change of the current cipher and hmac
4132 on the channel. Client can safely ignore the <cipher> argument
4133 (if it chooses to do so) since the CHANNEL_KEY packet will
4134 force the channel key change anyway. The <hmac> argument is
4135 important since the client is responsible of setting the new
4136 HMAC and the hmac key into use.
4138 * Fixed the CMODE command in the client library as well.
4140 * Tested CMODE command in router environment successfully.
4142 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Show the version of the remote client (or server) when connecting
4145 to the server. It is logged to the log file. Affected file
4146 is silcd/protocol.c.
4148 * Fixed the KILLED notify handling in the client library. The
4149 client must be removed from all channels when receiving the
4152 Also, do not remove the client entry when giving the KILL
4153 command but when the KILLED notify is received.
4155 * Removed silc_idlist_find_client_by_nickname from the server.
4156 Not needed anymore. Affected files silcd/idlist.[ch].
4158 * Implemented the CHANNEL_CHANGE notify type handling to the
4159 server. Affected file silcd/server.c.
4163 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Added silc_server_send_notify_invite to send the INVITE
4166 notify between routers.
4168 * Implemented the INVITE command correctly to the server.
4170 * Implemented the INVITE notify type handling in the server.
4172 * Implemented the INVITE command to the client library and on the
4175 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added function silc_server_get_client_resolve to find the
4178 client entry by ID from all ID lists and then resolve it
4179 (using WHOIS) if it cannot be found. Affected file is
4182 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4184 * Implemented the BAN command to the client library.
4186 * The JOIN command in the server now checks the invite list
4189 * Changed the silc_command_reply_payload_encode_va and the
4190 silc_command_payload_encode_va to support that if argument is
4191 NULL it ignores and checks the next argument. Affected file
4192 lib/silccore/silccommand.c.
4194 * Added silc_server_send_notify_ban to send the BAN notify
4195 type between routers.
4197 * Chaned the silc_notify_payload_encode to support that if
4198 argument is NULL it ignores and checks the next argument.
4199 Affected file lib/silccore/silcnotify.c.
4201 * Tested ban lists in router environment successfully.
4203 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Implemented BAN command to the server, in silcd/command.[ch].
4207 * Removed the BAN and INVITE_LIST modes from the CMODE command
4210 * Added function silc_string_match to regex match two strings.
4211 Affected files lib/silcutil/silcutil.[ch].
4213 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Redefined parts of the SilcChannelEntry in the server to support
4216 the new ban and invite lists.
4218 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Redefined the INVITE command. The same command can be used to
4221 invite individuals to the channel but also to manage the invite
4222 list of the channel (to add to and remove from the invite list).
4223 Updated the protocol specs.
4225 * Added new command SILC_COMMAND_BAN that can be used to manage
4226 the ban list of the channel. Updated the protocol specs.
4228 * Removed the channel modes: the SILC_CMODE_BAN and the
4229 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4230 in the CMODE command. The equivalent features are now available
4231 using INVITE and BAN commands. Updated the protocol specs.
4233 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4234 in the network about change in the current ban list. The notify
4235 type is not used by the client.
4237 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4238 support the invite lists.
4240 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Added new function silc_string_regexify that converts string
4243 including wildcard characters into regex string that can
4244 be used by the GNU regex library. Added into the file
4245 lib/silcutil/silcutil.[ch].
4247 Added silc_string_regex_combine to combine to regex strings
4248 into one so that they can be used as one regex string by
4249 the GNU regex library. Added into the file
4250 lib/silcutil/silcutil.[ch].
4252 Added silc_string_regex_match to match two strings. It returns
4253 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4255 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Imported GNU regex to the soruce tree into lib/contrib.
4258 Fixed some compiler warning from the regex.c.
4260 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Fixed MOTD command in the server to work in router environment.
4264 * Fixed the MOTD command in the client library to support
4265 the server argument in the command.
4267 * Added `nickname_len' argument to the silc_idlist_add_client
4268 in the server, as the `nickname' argument may be binary data
4271 * Added silc_idlist_get_channels to return all channels from
4274 * Implemented LIST command to the server. Affected file is
4277 * Implemented the LIST command to the client library and on the
4280 * Added [<user count>] argument to the LIST command reply.
4281 With private channels the user count is not shown.
4283 * Updated TODO and README.
4285 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * The client entry's data.registered must be TRUE even with
4288 global client entry on global client list. The data.registered
4289 is used to check whether the client is anymore in the network,
4290 for example with WHOWAS command so it must be valid.
4292 * Fixed the WHOWAS command in the server. It now actually works
4293 in router environment. Added function into silcd/command_reply.c
4294 silc_server_command_reply_whowas_save.
4296 * Added silc_idlist_purge function to the silcd/idlist.c
4297 to periodically purge the ID Cache.
4299 * Fixed INFO command in the server. It works now in router
4300 environment. Added <server name> argument to the INFO command
4301 reply. Updated the protocol specs.
4303 * Fixed minor bug in silc_idcache_purge to not purge if the
4304 expire value is zero.
4306 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4307 they were buggy because of the WHOWAS information.
4309 * Fixed local command MSG to handle the async resolving of
4310 the remote client properly. It used to fail the first MSG.
4311 Affected file silc/local_command.c.
4313 * Added `data_len' field to SilcIDCache context.
4315 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Update TODO. Todo in commands in the server.
4319 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4322 used by routers as broadcast packet to inform other routers
4323 about the changed user mode.
4325 Implemented the notify handling in the server. Affected file is
4326 silcd/packet_receive.c. Added the function
4327 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4329 * Added new generic Channel Payload and deprecated the New Channel
4330 Payload. The New Channel Payload is now the generic Channel
4333 * Added new argument `mode' to the silc_server_send_new_channel
4334 as it is required in the Channel Payload now.
4336 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4337 and created a new and real SilChannelPayload to represent the
4338 new generic Channel Payload. Implemented the encode/decode
4339 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4341 * Added silc_server_get_client_channel_list to return the list
4342 of channels the client has joined for WHOIS command reply.
4343 Affected file silcd/server.[ch].
4345 * Implemented the channel list sending in the WHOIS command reply
4346 in server and in the client.
4348 Implemented the channel list displaying on the user interface
4349 as well. Affected file silc/client_ops.c.
4351 * Added silc_channel_payload_parse_list to parse list of Channel
4352 Payloads. It returns SilcDList list of SilcChannelPayloads.
4353 Client for example can use this function to parse the list of
4354 channels it receives in the WHOIS command reply. The caller
4355 must free the list by calling silc_channel_payload_list_free.
4356 Affected files lib/silccore/silcchannel.[ch].
4358 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Added one new argument <user mode> to the WHOIS command reply
4361 to return the mode of the user in SILC. Updated the protocol
4364 Implemented it to the server and client.
4366 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Fixed the mode printing on the user interface on joining.
4369 Affected file silc/client_ops.c.
4371 * Implemented the UMODE command and user modes in general to the
4372 client library and to the user interface.
4374 * Implemented the UMODE command to the server.
4376 * The server now sends UNKNOWN_COMMAND error status if client sends
4377 unknown command. Affected file silcd/command.c.
4379 * All server commands now handle the command identifier the right
4380 way when sending the command reply to the client. The client can
4381 use to identify the command replies with the identifier.
4383 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Added silc_server_get_client_route to resolve the route to
4386 the client indicated by the client ID. Affected file is
4389 * Added silc_server_relay_packet as general function to relay
4390 packet to arbitrary destination. This deprecates functions
4391 like _send_private_message_key, _relay_notify etc. Affected
4392 file is silcd/packet_send.[ch].
4394 Removed silc_server_send_key_agreement,
4395 silc_server_send_private_message_key and
4396 silc_server_packet_relay_notify functions from the file
4397 silcd/packet_send.[ch].
4401 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4402 server. Affected file silcd/packet_receive.[ch].
4404 * Implemented the KILL command to the client. Implemented the
4405 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4406 Affected files lib/silcclient/command[_reply].c and
4407 lib/silcclient/client_notify.c. Implemented the KILL notify
4408 printing in the user inteface.
4410 * Fixed a lot silc_parse_nick memory leaks from the client
4411 library in the file lib/silcclient/command.c.
4413 * Changed the silc_server_send_notify_on_channels's `sender'
4414 argument from SilcSocketConnection to SilcClientEntry to
4415 check the sender as entry and not as connection object and not
4416 to send to the client provided as argument. The affected file
4417 is silcd/packet_send.[ch].
4419 * The notify packets that are destined directly to the client used
4420 to not to be processed by the server. Now changed that and the
4421 server processes all notify packets. After relaying the packet
4422 to the client the notify packet is processed in the server.
4424 * The silc_server_free_client_data now checks whether there is
4425 pending outgoing traffic for the client and purges the data to
4426 the network before removing the client entry.
4428 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4431 an client is killed from the SILC Network. Updated the protocol
4434 Added new function silc_server_send_notify_killed to the
4435 silcd/packet_send.[ch].
4437 * Added function silc_server_packet_relay_notify to relay notify
4438 packets that are destined directly to a client. In this case
4439 the server does not process the notify packets but merely relays
4440 it to the client. Affected file silcd/packet_send.[ch].
4442 Added also silc_server_packet_process_relay_notify to check
4443 whereto relay the notify. Affected file is
4444 silcd/packet_receive.[ch].
4446 * Implemented the KILL command to the server.
4450 * Added the backup schema desgined last fall to the protocol
4451 specs for everyone to see. The specification is in the
4452 *-spec-xx.txt draft and the packet type definitions for the
4453 backup routers is in *-pp-xx.txt draft. Thusly, added also
4454 new packet type SILC_PACKET_CELL_ROUTERS.
4456 * A big security problem in the implementation discovered. The
4457 signoff of an client did not cause new channel key generation
4458 which it of course should've done. The channel keys must be
4459 always re-generated when client leaves (or signoffs) the channel.
4460 The silc_server_remove_from_channels funtion now handles
4461 the channel key re-generation.
4463 * Added `sender' argument to the silc_server_send_notify_on_channels
4464 to not to send the client provided as argument. Affected file
4465 silcd/packet_send.[ch].
4467 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Implemented OPER and SILCOPER commands into the server and
4472 * Added silc_auth_verify and silc_auth_verify_data to verify
4473 the authentication directly from the authentication payload.
4474 It supports verifying both passphrase and public key based
4475 authentication. Affected file lib/silccore/silcauth.[ch].
4477 * Added `hash' field to the SilcIDListData structure. It is the
4478 hash negotiated in the SKE protocol. Affected file is
4481 * Slight redesigning of the SilcAuthPayload handling routines.
4482 Do not send SilcPKCS but SilcPublicKey as argument.
4484 * Implemented the public key authentication support to the
4485 serverconfig. The public key is loaded from the provided path
4486 and saved as authentication data to void * pointer. Thus,
4487 changed the unsigned char *auth_data to void *auth_data;
4489 * Fixed SHUTDOWN command to send the reply before the server
4490 is shutdown. :) Affected file silcd/command.c.
4492 * Fixed fatal bug in CONNECT command. The hostname was invalid
4493 memory and server crashed. Affected file silcd/command.c.
4495 * Fixed fatal bug in CLOSE command. The server_entry became
4496 invalid but was referenced later in the command. Affected file
4499 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Fixed fatal bug in failure packet handling. Server ignored
4502 the failure and thus crashed when it came.
4506 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4509 that the command may be executed only once in (about) 2 seconds.
4510 The old SILC_CF_LAG flag is same but allows command bursts up
4511 to five before limiting.
4513 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4514 server code. Various commands now includes the CF_LAG_STRICT
4515 flag to disallow any kind of miss-use of the command.
4517 * Fixed the silc_buffer_unformat to not to allocate any data
4518 if the length of the data is zero. It used to allocate the
4519 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4521 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * Changed the format of AdminConnection configuration section
4524 in the server. Added username of the admin to the format.
4525 Affected files silcd/serverconfig.[ch].
4527 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4528 to return admin configuration data by host, username and/or
4531 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Implemented WHOWAS command to the server. Added the functions:
4535 silc_server_command_whowas_parse,
4536 silc_server_command_whowas_send_reply,
4537 silc_server_command_whowas_from_client and
4538 silc_server_command_whowas_from_server
4540 * Added <Client ID> argument to the WHOWAS command reply. Updated
4541 the protocol specs accordingly.
4543 * Implemented WHOWAS command and command_reply to the client
4546 Implemented the WHOWAS printing on the user interface.
4548 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added new argument to the WHOWAS command reply, the real name.
4551 It is an optional argument. Updated the protocol specs.
4553 * Added SilcIDCacheDestructor callback that is registered when
4554 the SilcIDCache is allocated. The callback is called when
4555 an cache entry in the ID Cache expires, or is purged from the
4556 cache. Added into lib/silccore/idcache.[ch].
4558 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4559 to destruct the client entries when the cache entry expires.
4560 Other ID Cache's in server and in the client library ignores
4563 * If the ID Cache entry's `expire' field is zero then the entry
4564 never expires. Added boolean `expire' argument to the
4565 silc_idcache_add function in the lib/silccore/idcache.[ch].
4566 If it is TRUE the default expiry value is used.
4568 * Added silc_server_free_client_data_timeout that is registered
4569 when client disconnects. By default for 5 minutes we preserve
4570 the client entry for history - for WHOWAS command.
4572 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Added support to the server to enforce that commands are not
4575 executed more than once in 2 seconds. If server receives
4576 commands from client more frequently, timeout is registered
4577 to process the commands. Affected file silcd/command.c.
4578 Added new function silc_server_command_process_timeout.
4580 * Changed NICK_NOTIFY handling in client library to check that
4581 if the client's nickname was changed, so there is no need to
4582 resolve anything from the server.
4584 * Removed error printing from the WHOIS and IDENTIFY commands.
4585 If error occurs then it is ignored silently in the client library.
4586 The application, however, may map the received error to
4587 human readable error string. The application currently maps
4588 the NO_SUCH_NICKNAME error to string.
4590 * Made the command status message public to the application. Moved
4591 them from lib/silcclient/command_reply.c to
4592 lib/silcclient/command_reply.h. The application can map the
4593 received command status to the string with the
4594 silc_client_command_status_message function.
4596 * Added check to the server to check that client's ID is same
4597 as the Source ID in the packet the client sent. They must
4600 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4602 * Added dist-bzip hook to the Makefile.am to make bzip2
4603 compressed distributions.
4605 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4607 * Server now enforces the maximum length for the nickname and
4608 the channel as protocol specification dictates. 128 bytes for
4609 nickname and 256 bytes for channel name.
4611 * Moved the WHOIS printing to the application. The client libary
4612 does not print out the WHOIS information anymore, the application
4613 must do it. Renamed silc_client_command_reply_whois_print to
4614 the silc_client_command_reply_whois_save.
4616 The client's idle time is also sent to the application now, and
4617 the idle is shown on screen.
4619 * Added silc_client_command_reply_identify_save to save the
4620 received IDENTIFY entries.
4622 * Do not check for channel private keys in message sending and
4623 reception if the channel does not have the PRIVKEY mode set.
4624 Affected file lib/silclient/client_channel.c.
4626 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4629 just surfaced after chaning the JOIN procedure.
4631 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added silc_client_get_clients_by_list to get client entries
4634 from Client ID list, that is returned for example by JOIN
4635 and USERS command replies. The application should use this
4636 function for example when JOIN command reply is received to
4637 resolve the clients already on the channel (library does not
4638 do that anymore as USERS command reply is not used in the JOIN
4639 procedure anymore). Affected files lib/silcclient/silcapi.h and
4640 lib/silcclient/idlist.c.
4642 * JOIN command reply and USERS command reply returns now SilcBuffer
4643 pointers instead of unsigned char pointers when returning
4644 the client list and mode list.
4646 * Added <Client ID> argument to the JOIN command reply, mainly
4647 for the server to identify for which client the command was
4648 originally sent. Updated protocol specs accordingly.
4650 * Added SilcDlist private_key pointer to the SilcChannelEntry
4651 in the client to support the channel private keys. Affected
4652 file is lib/silcclient/idlist.h.
4654 * Added SilcChannelPrivateKey argument to the function
4655 silc_client_send_channel_message so that application can choose
4656 to use specific private ke if it wants to. If it is not provided,
4657 the normal channel key is used, unless private keys are set.
4658 In this case the first (key that was added first) is used
4659 as the encryption key.
4661 * Implemented the support for channel private key handling.
4662 Implemented the following functions:
4664 silc_client_add_channel_private_key,
4665 silc_client_del_channel_private_keys,
4666 silc_client_del_channel_private_key,
4667 silc_client_list_channel_private_keys and
4668 silc_client_free_channel_private_keys
4670 Affected file lib/silcclient/client_channel.c.
4672 * Added the support for the private keys in the channel message
4673 sending and encryption and in the message reception and
4674 decryption. Affected funtions are
4675 silc_client_send_channel_message and silc_client_channel_message.
4677 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Added SKE's key verify callback to the client library's
4680 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4682 * Removed the statement that server (or router) must send USERS
4683 command reply when joining to the channel so that the client
4684 knows who are on the channel. Instead, the client list and
4685 client's mode list is now sent in the JOIN command reply to the
4686 client who joined channel. This is better solution.
4688 * Added function silc_server_get_users_on_channel and function
4689 silc_server_save_users_on_channel to the silcd/server.[ch].
4691 * Removed function silc_server_command_send_users from the
4694 * Do not show topic on the client library anymore. The topic is
4695 sent in the command reply notify to the application and the
4696 application must show the topic now.
4698 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Added client searching by nickname hash into the IDENTIFY and
4701 WHOIS commands in the server as they were clearly missing from
4702 them. Affected file is silcd/command.c.
4704 * Fixed a bug in private message receiving in the client library.
4705 The remote ID was freed and it wasn't supposed, now it is
4708 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4710 * Minor fix to the channel payload; allocate the data area, as it
4711 needs to be of specific length.
4713 * If the key agreement port is zero then the operating
4714 system will define the bound port. Affected files are
4715 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4717 * Added new function silc_channel_payload_decrypt into the file
4718 lib/silccore/silcchannel.[ch].
4720 * Moved the channel message etc, check from silc_packet_decrypt
4721 to applications. The library calls now a generic
4722 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4723 when the packet is either normal or special. This was done to
4724 allow more wide range of checking that was not allowed when
4725 the code was in library. Now applications can do virtually any
4726 checks to the packet and return to the library the decision how
4727 the packet should be processed. Affected files are
4728 lib/silccore/silcpacket.[ch].
4730 Added silc_server_packet_decrypt_check to the server and
4731 silc_client_packet_decrypt_check to the client library.
4733 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4734 to send with specified source and destination information.
4736 * Channel message delivery between routers was broken after the
4737 channel key distribution was fixed earlier. The channel key
4738 was used be to distributed to other routers as well which is not
4739 allowed by the protocol. Now this is fixed and channel keys
4740 really are cell specific and the channel message delivery between
4741 routers comply with the protocol specification.
4743 * Fixed various commands in server to check also the global list
4744 for the channel entry and not just the local list. The affected
4745 file silcd/command.c.
4747 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Added assert()s to buffer formatting and unformatting routines
4750 to assert (if --enable-debug) when error occurs. Affected
4751 file: lib/silcutil/silcbuffmt.c.
4753 * Changed to auto-reconnect to check whether the remote host is
4754 router and register the re-connect timeout if it is. It used
4755 to check that whether we are normal server, but router must do
4756 auto-reconnect with another router as well. Affected file
4759 * Removed the [<key len>] option from CMODE command as the cipher
4760 name decides the key length, nowadays. See the defined ciphers
4761 from the protocol specification.
4763 * Added [<hmac>] option to the CMODE command to define the HMAC
4764 for the channel. Added SILC_CMODE_HMAC channel mode.
4766 * Added [<hmac>] option for the JOIN command so that user can
4767 select which HMAC is used to compute the MACs of the channel
4770 * Added Hmac field to the Channel Message Payload. The integrity
4771 of plaintext channel messages are now protected by computing
4772 MAC of the message and attaching the MAC to the payload. The
4773 MAC is encrypted. Now, it is clear that this causes some
4774 overhead to the size of the packet but rationale for this is that
4775 now the receiver can verify whether the channel message decrypted
4776 correctly and also when private keys are set for the channel the
4777 receiver can decrypt the packet with several keys and check from
4778 the MAC which key decrypted the message correctly.
4780 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4781 lib/silccrypt/silccipher.[ch].
4783 * Added silc_hash_len to return the digest length into the
4784 lib/silcrypt/silchash.[ch].
4786 * Rewrote parts of Silc Channel Payload interface in the
4787 lib/silccore/silcchannel.[ch]. The encode function now also
4788 encrypts the packet and parse function decrypts it.
4790 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Fixed a minor formatting bug in the SKE's key material processing.
4793 It actually might have processed the keys wrong way resulting
4796 * Redefined the mandatory HMAC algorithms and added new algorithms.
4797 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4798 and hmac-md5 truncated to 96 bits. The mandatory is now
4799 hmac-sha1-96. Rest are optional (including the one that used
4800 to be mandatory). Rationale for this is that the truncated HMAC
4801 length is sufficient from security point of view and can actually
4802 make the attack against the HMAC harder. Also, the truncated
4803 HMAC causes less overhead to the packets. See the RFC2104 for
4806 * Added new [hmac] configuration section. The SKE used to use
4807 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4808 is of course wrong. The official names that must be proposed in
4809 the SKE are the ones defined in the protocol specification
4810 (hmac-sha1-96 for example). The user can configure any hmac
4811 using any hash function configured in the [hash] section. At
4812 least, the mandatory must be configured.
4814 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4816 * Added HMAC list to the SKE proposal list. It has now both
4817 hash algorithm list and HMAC list. This makes the protocol
4818 incompatible with previous versions. The SKE now seems to work
4819 the way it is supposed to work, for the first time actually.
4821 * Defined plain Hash algorithms to the protocol specification.
4824 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Implemented support for key agreement packets into the server.
4827 Added functions silc_server_key_agreement and
4828 silc_server_send_key_agreement. Other than these functions,
4829 server has nothing to do with this packet.
4831 * Added support for private message key packets into the server.
4832 Added functions silc_server_private_message_key and
4833 silc_server_send_private_message_key.
4837 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4838 called in the protocol's final callback instead in the END
4839 protocol state. This makes a little more sense and in the same
4840 time in client we can use the same protocol routines for normal
4841 key exchange and to key agreement packet handling as well.
4843 * Added to both client's and server's KE protocol context the
4844 SilcSKEKeyMaterial pointer to save the key material. We will
4845 bring the key material to the protocol's final callback by doing
4846 this. The final callback must free the key material.
4848 * Added SKE's packet_send callback into client's KE protocol
4849 context so that the caller can choose what packet sending function
4850 is used. This way we can use different packet sending when
4851 doing normal SKE when doing key agreement packet handling (in
4852 the key agreement packet handling we do not want to encrypt
4855 * Implemented the responder side of the key agreement routines
4856 in the client. The client can now bind to specified port and
4857 accept incoming key negotiation. The key material is passed
4858 to the application after the protocol is over.
4860 * Implemented the processing of incoming Key Agreement packet
4861 in the client. Added function silc_client_key_agreement to
4864 * Implemented the intiator side of the key agreement routines
4865 in the client. The client can now initiate key agreement with
4866 another remote client. The key material is passed to the
4867 application after the protocol is over.
4869 * Created client_keyagr.c to include all the key agreement
4872 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4873 SILC_TASK_CALLBACK except that it is not static.
4875 * Created client_notify.c and moved the Notify packet handling
4876 from the client.[ch] into that file.
4878 * Created client_prvmsg.c and moved all private message and
4879 private message key routines from the client.[ch] into that file.
4881 * Create client_channel.c and moved all channel message and
4882 channel private key routines from the client.[ch] into that file.
4884 * Changed silc_client_get_client_by_id_resolve to resolve with
4885 WHOIS command instead of IDENTIFY command, in the file
4886 lib/silclient/idlist.c.
4888 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Implemented the SKE's responder side to the Client library.
4892 * When FAILURE is received to the protocol do not trust it
4893 blindly. Register a timeout to wait whether the remote closes
4894 the connection as it should do it, only after that process the
4895 actual failure. This was changed to both client and server.
4897 * Added client_internal.h to include some of the structures
4898 there instead of client.h in lib/silcclient/.
4900 * Added function silc_task_unregister_by_callback to unregister
4901 timeouts by the callback function.
4903 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Some "Incomplete WHOIS info" errors has been appearing on the
4906 log files. Took away the entry->userinfo check from WHOIS
4907 reply sending. The entry->userinfo is now " " if client did not
4908 provide one. I thought this was fixed earlier but something
4909 is wrong still. Let's see if the error still appears.
4911 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4913 * Fixed a minor bug in the login when the channel key is
4914 re-generated in the server. It used to generate the key in
4915 wrong order and thus caused problems in the channel traffic.
4917 * Fixed a minor bug in channel key distsribution after
4918 KICK command. The key was not sent to the router even though
4921 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Added silc_ske_process_key_material_data as generic routine
4924 to process any key material as the SILC protocol dictates. The
4925 function is used by the actual SKE library but can be used by
4926 applications as well. This relates to the private message keys
4927 and the channel private keys since they must be processed the
4928 same way the normal SILC session keys. The protocol dictates
4929 this. Affected files: lib/silcske/silcske.[ch].
4931 Added also silc_ske_free_key_material to free the
4932 SilcSKEKeyMaterial structure.
4934 * Defined silc_cipher_set_key function to set the key for
4935 cipher without using the object's method function. The affected
4936 files: lib/silccrypt/silccipher.[ch].
4938 * Implemented silc silc_client_add_private_message_key,
4939 silc_client_add_private_message_key_ske,
4940 silc_client_del_private_message_key,
4941 silc_client_list_private_message_keys and
4942 silc_client_free_private_message_keys functions in the
4945 Added functions silc_client_send_private_message_key to send
4946 the Private Message Key payload and silc_client_private_message_key
4947 to handle incoming Private Message Key payload.
4949 * Added Cipher field to the Private Message Key payload to set
4950 the cipher to be used. If ignored, the default cipher defined
4951 in the SILC protocol (aes-256-cbc) is used.
4953 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Removed lib/silcclient/ops.h file.
4957 Redefined parts of the SILC Client Library API. Created new
4958 file silcapi.h that deprecates the ops.h file and defines the
4959 published Client Library API. Defined also private message key
4960 API and channel private key API into the file.
4962 This is the file that the application must include from the
4963 SILC Client Library. Other files need not be included by
4964 the application anymore.
4966 * Added new key_agreement client operation callback and also
4967 defined the Key Agreement library API for the application.
4969 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4972 is used by clients to request key negotiation between another
4973 client in the SILC network. If the negotiation is started it
4974 is performed using the SKE protocol. The result of the
4975 negotiation, the secret key material, can be used for example
4976 as private message key.
4978 Implemented the Key Agreement payload into the files
4979 lib/silccore/silauth.[ch].
4981 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Redefined ciphers for the SILC protocol. Added some new ciphers
4984 and defined the key lengths for the algorithms. Changed the
4985 code accordingly. The default key length is now 256 bits.
4987 * Fixed SKE key distribution function silc_ske_process_key_material
4988 when the key length is more than 128 bits. The default key
4989 length in SILC is now 256 bits.
4991 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4992 to indicate unsupported algorithm.
4994 * Renamed rijndael.c to aes.c and all functions as well.
4996 * Fixed a long standing channel key setting bug in client library.
4997 Weird that it has never surfaced before.
4999 * Fixed bug in channel deletion. If the entire channel is removed
5000 then it must also delete the references of the channel entry
5001 from the client's channel list as the client's channel entry and
5002 the channel's client entry share same memory.
5004 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Implemented CONNECT and SHUTDOWN commands in the client.
5008 * Implemented CLOSE command to the client.
5010 * Added the function silc_idlist_find_server_by_name into the
5011 files silcd/idlist.[ch].
5013 Added the function silc_idlist_find_server_by_conn into the
5014 files silcd/idlist.[ch].
5016 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * DIE command was renamed to SHUTDOWN. Updated the both code
5021 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5022 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5024 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5027 * Added function silc_server_create_connection function to create
5028 connection to remote router. My server implementation actually
5029 does not allow router to connect to normal server (it expects
5030 that normal server always initiates the connection to the router)
5031 so the CONNECT command is only good for connecting to another
5034 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5037 or some other client was kicked from the channel.
5039 Implemented the handling of the notify type to both client
5042 Implemented silc_server_send_notify_kicked to send the KICKED
5043 notify. It is used to send it to the server's primary router.
5045 * Implemented the KICK command into server and client.
5047 * Added `query' argument to the silc_idlist_get_client function
5048 to indicate whether to query the client from server or not if
5051 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5052 to indicate that the client is not channel founder.
5056 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Removed the rng context from SilcPacketContext structure and
5059 changed that the packet routine uses the Global RNG API.
5061 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Added support for quit message that client can "leave" on the
5064 channel when it quits the SILC. It is ditributed inside the
5065 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5067 Added silc_server_free_client_data that will take the
5068 signoff message as argument.
5070 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5072 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Updated parts of the protocol specification to keep it up
5077 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5080 payloads in one packet.
5082 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5083 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5084 use now the new List flag.
5086 * Also deprecated the following packet types: REPLACE_ID,
5087 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5089 * Added list support for Notify packet in server.
5091 * Added silc_server_send_notify_channel_change to send the
5092 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5093 the silc_server_send_replace_id.
5095 * Added silc_server_send_notify_nick_change to send the
5096 NICK_CHANGE notify type. Deprecates the function
5097 silc_server_send_replace_id.
5099 * Added silc_server_send_notify_join to send the JOIN notify type.
5100 Deprecates the function silc_server_send_new_channel_user.
5102 * Added silc_server_send_notify_leave to send LEAVE notify type.
5103 Deprecates the function silc_server_send_remove_channel_user.
5105 * Added silc_server_send_notify_cmode and
5106 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5107 types. Deprecates the silc_server_send_set_mode function.
5109 * Added SERVER_SIGNOFF notify type to indicate that server has
5110 quit. This means that all clients on the channel from that
5111 server will drop. This can be also used when netsplit happens.
5113 Deprecated REMOVE_ID packet type since it is not needed anymore
5116 Added silc_server_send_notify_server_signoff to send the
5117 SERVER_SIGNOFF notify type. Deprecates the function
5118 silc_server_send_remove_id.
5120 Added also silc_server_send_notify_signoff to send the
5121 SIGNOFF notify type.
5123 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5124 SILC protocol from this day on. Changed the protocol
5125 specification as well.
5127 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5128 notify type. It is used between routers to notify about
5129 topic changes on a channel.
5131 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5134 * Partly updated the protocol specification to comply with the
5135 changes now made. It is still though a bit outdated.
5137 * The JOIN notify type now takes one extra argument <Channel ID>.
5138 The packet used to be destined to the channel but now the
5139 JOIN type may be sent as list thus it is impossible to
5140 destine it to any specific channel. By adding this argument
5141 it is again possible.
5143 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Added CREDITS file. The CHANGES and CREDITS file will appear
5146 in the distribution as well.
5148 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5151 types in the server's silcd/packet_receive.c.
5153 * Implemented CMODE and CUMODE to work in router environment.
5155 * Fixed minor encoding and decoding buglet from the
5156 lib/silccore/silcmode.c.
5158 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5161 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5163 * Changed all SilcConfigServer* and silc_config_server* to
5164 SilcServerConfig* and silc_server_config*, respectively.
5167 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Associated the ID (client or server ID) to the Authentication
5170 Payload to avoid any possibility of forging. Updated the
5171 protocol specification and the code accordingly.
5173 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * The RSA key length is now save to the RsaKey context in the
5176 key generation process in lib/silccrypt/rsa.c. The key length
5177 is now used to figure out the maximum size of the block allowed
5178 to be encrypted/signed.
5180 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5181 is equivalent to the silc_mp_mp2bin but does not allocate any
5184 * Changed silc_mp_mp2bin API to take length argument. If it is
5185 non-zero then the buffer is allocated that large. If zero, then
5186 the size is approximated using silc_mp_sizeinbase, which however
5189 * Created Global RNG API which is global RNG that application can
5190 initialize. After initializing, any routine anywhere in the
5191 code (including library) can use RNG without allocating a new
5192 RNG object. This was done to allow this sort of use of the
5193 RNG in code that has no chance to allocate RNG object. All
5194 applications currently allocate this and many routines in the
5195 library use this. Affected file lib/silccrypt/silcrng.[ch].
5197 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5198 it to use the Global RNG API.
5200 * Defined Authentication Payload into protocol specification that
5201 is used during SILC session to authenticate entities. It is
5202 used for example by client to authenticate itself to the server
5203 to obtain server operator privileges.
5205 Implemented this payload into the lib/silccore/silcauth.[ch].
5206 Implemented also routines for public key based authentication
5207 as the new protocol specification dictates.
5209 Moved definitions of different authentication methods from
5210 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5212 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5213 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5214 silc_pkcs_verify_with_hash functions into the file
5215 lib/silccrypt/silcpkcs.[ch].
5217 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * The client entry's userinfo pointer must be always valid.
5220 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5221 will fail since it requires the userinfo. Now, the userinfo
5222 is allocated as "" if actual userinfo does not exist. Actually,
5223 it must exist and it is totally Ok to drop client connections
5224 that does not announce the userinfo. However, we will make
5225 this workaround for now.
5227 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5228 to return the remote port by socket.
5230 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5232 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5233 SILC_SERVER_PENDING_EXEC and added an new macro
5234 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5235 data or when error occurs while processing the pending command.
5237 Added new argument `destructor' into silc_server_command_pending
5238 and to the SilcServerCommandPending object. This destructor is
5239 now called after calling the pending callback or if error occurs
5240 immediately. If error occurs the actual pending callback won't
5241 be called at all - only the destructor. The destructor may be
5242 NULL if destructor is not needed.
5244 All this applies for client library code as well. Similar
5245 changes were made there as well for the pending commands.
5247 In the client, the application must now allocate the
5248 SilcClientCommandContext with the silc_client_command_alloc
5251 * Added reference counter to the SilcServerCommandContext. Added
5252 function silc_server_command_alloc and silc_server_command_dup
5255 Same type of functions added to the client library for the same
5258 * Removed the cmd_ident from IDListData away since it is now
5259 global for all connections. It is the command identifier used
5260 in command sending and with pending commands. The affected file
5263 * Added reference counter to the SilcSocketConnection objecet to
5264 indicate the usage count of the object. The object won't be
5265 freed untill the reference counter hits zero. Currently only
5266 server uses this, and client ignores it. The client must be
5267 set to use this too later. The affected files are
5268 lib/silccore/silcsockconn.[ch]. Added also the function
5269 silc_socket_dup to increase the reference counter.
5271 This was mainly added because it is possible that the socket
5272 is removed underneath of pending command or other async
5273 operation. Now it won't be free'd and proper DISCONNECTING
5274 flags, etc. can be set to avoid sending data to connection that
5275 is not valid anymore.
5277 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5278 the connection. After that it sets SILC_SET_DISCONNECTED.
5279 It is, however, possible that the socket data is not still freed.
5280 The silc_server_packet_process now checks that data is not
5281 read or written to connection that is DISCONNECTED. The socket
5282 get's freed when the reference counter hits zero.
5284 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Changed the client operation API: channel_message operation's
5287 `sender' is now the client entry of the sender, not the nickname
5288 and the `channel' is the channel entry, not the channel name.
5290 In the private_message operation the `sender' is now also the
5291 client entry of the sender not the nickname.
5293 Affected file is lib/silcclient/ops.h and all applications
5294 using the client operations.
5296 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Moved the calling of ops->connect() from connect_to_server_final
5299 into receive_new_id functin since that is the point when the
5300 client is actually allowed to send traffic to network. The
5301 affected file is lib/silcclient/client.c.
5303 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5306 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5307 (if needs broadcasting) instead of broadcasting the packets one
5308 by one which would make a burst in the network traffic.
5310 * Added `broadcast' argument to the functions in silcd/server.[ch]
5311 silc_server_create_new_channel[_with_id] to indicate whether
5312 to send New Channel packet to primary router.
5314 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added new function into the silcd/server.[ch] files:
5317 silc_server_create_new_channel_with_id to create new channel with
5318 already existing Channel ID.
5320 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5321 lib/silccore/silcpacket.h. This packet is used t send list of
5322 Set Mode payloads inside one packet. Server uses this to set
5323 the modes for the channels and clients on those channels, that it
5324 announced to the router when it connected to it. The protocol
5325 specification has been updated accordingly.
5327 * The silc_server_new_channel did not handle the packet coming
5328 from normal server as it normally does not send that. However,
5329 when it announces its channels it does send it. Implemented
5330 the support for that.
5332 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5333 into the file lib/silccore/id.h.
5335 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Fixed memory leaks in the functions silc_idlist_del_client,
5338 silc_idlist_del_channel and silc_idlist_del_server in the file
5339 silcd/idlist.c. All of those leaked like a sieve.
5341 * Fixed some small memory leaks in the client's function
5342 silc_client_notify_by_server.
5344 * Added functions into silcd/server.c: silc_server_announce_clients,
5345 silc_server_announce_channels and silc_server_announce_server.
5346 These functions are used by normal and router server to announce
5347 to its primary router about clients, channels and servers (when
5348 router) that we own. This is done after we've connected to the
5351 These functions effectively implements the following packet types:
5352 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5353 and SILC_PACKET_NEW_ID_LIST.
5355 * Added new functions into the silcd/packet_receive.[ch]:
5356 silc_server_new_id_list, silc_server_new_channel_list and
5357 silc_server_new_channel_user_list to handle the incoming
5358 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5360 * Added support of changing Channel ID in the function
5361 silc_server_replace_id. If the server that announces a channel
5362 to the router already exists in the router (with same name but
5363 with different Channel ID), router is responsible to send
5364 Replace ID packet to the server and force the server to change
5365 the Channel ID to the one router has.
5367 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5368 client that the Channel ID has been changed by the router. The
5369 normal server sends this to the client. Client must start using
5370 the new Channel ID as the channel's ID.
5372 Implemented handling of this new type into lib/silcclient/client.c
5373 into the function silc_client_notify_by_server.
5375 * Added new function silc_idlist_replace_channel_id into the files
5376 silcd/idlist.[ch] to replace the Channel ID.
5378 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Call silc_server_command_identify_check always when processing
5381 the IDENTIFY command in silcd/command.c
5383 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5386 send keepalive packets. The packet can be sent by clients,
5387 servers and routers.
5389 Added function silc_socket_set_heartbeat into the file
5390 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5391 If not set, the heartbeat is not performed. The actual
5392 heartbeat is implemented in the low level socket connection
5393 library. However, application is responsible of actually
5396 Added silc_server_send_heartbeat to send the actual heartbeat
5397 packet into silcd/packet_send.[ch]. Server now performs
5398 keepalive with all connections.
5400 * Added silc_task_get_first function into lib/silcutil/silctask.c
5401 to return the timeout task with shortest timeout. There was a bug
5402 in task unregistration that caused problems. TODO has been
5403 updated to include that task system must be rewritten.
5405 * The client library will now resolve the client information when
5406 receiving JOIN notify from server for client that we know but
5407 have incomplete information.
5409 * Rewrote parts of silc_server_remove_from_channels and
5410 silc_server_remove_from_one_channel as they did not remove the
5411 channel in some circumstances even though they should've.
5413 * Encryption problem encountered in server:
5415 The LEAVE command used to send the Channel Key packet to the
5416 router immediately after generating it. However, the code
5417 had earlier sent Remove Channel user packet but not immediately,
5418 ie. it was put to queue. The order of packets in the router
5419 was that Channel Key packet was first and Remove Channel User
5420 packet was second, even though they were encrypted in the
5421 reverse order. For this reason, MAC check failed. Now, this
5422 is fixed by not sending the Channel Key packet immediately but
5423 putting it to queue. However, this is more fundamental problem:
5424 packets that are in queue should actually not be encrypted
5425 because packets that are sent immediately gets encrypted
5426 actually with wrong IV (and thus MAC check fails). So, packets
5427 that are in queue should be encrypted when they are sent to
5428 the wire and not when they put to the queue.
5430 However, the problem is that the current system has not been
5431 designed to work that way. Instead, the packet is encrypted
5432 as soon as possible and left to the queue. The queue is then
5433 just purged into wire. There won't be any fixes for this
5434 any time soon. So, the current semantic for packet sending
5437 o If you send packet to remote host and do not force the send
5438 (the packet will be in queue) then all subsequent packets to the
5439 same remote host must also be put to the queue. Only after the
5440 queue has been purged is it safe again to force the packet
5443 o If you send all packets immediately then it safe to send
5444 any of subsequent packets through the queue, however, after
5445 the first packet is put to queue then any subsequent packets
5446 must also be put to the queue.
5448 Follow these rules and everything works fine.
5450 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added new function silc_server_remove_clients_by_server to
5453 remove all client entries from ID list when the server connection
5454 is lost. In this case it is also important to invalidate all
5455 client entires as they hold the invalid server entry. This
5456 fixes fatal bug when server has lost connection and will reconnect
5459 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Made some sanity checks to silc_server_daemonise like to check
5462 whether the requested user and group actually exists.
5464 * Added sanity check to SKE's silc_ske_responder_finish to check
5465 that the public and private key actually is valid.
5467 * Invalidate the client's nickname when receiving Replace ID
5468 packet and the Client ID is being replaced. This means that the
5469 server will query the nickname if someone needs it (client)
5472 * Sort the ID Cache in client library when the ID Cache data
5473 has changed (needs sorting).
5475 * Do not allow for SILC client to create several connections to
5476 several servers. The client does not support windows right now
5477 and generating multiple connections causes weird behaviour.
5479 Irssi-silc client does support windows and can handle several
5480 connections without problems, see: www.irssi.org and SILC plugin.
5482 * Fixed some places where client was added to the IDList. The
5483 rule of thumb is following (in order to get everything right):
5484 If the client is directly connected local client then the
5485 `connection' argument must be set and `router' argument must be
5486 NULL to silc_idlist_add_client function. If the client is not
5487 directly connected client then the `router' argument must
5488 bet set and the `connection' argument must be NULL to the
5489 silc_idlist_add_client function.
5491 * The funtion silc_server_packet_send_local_channel actually did
5492 not check whether the client was locally connected or not. It
5493 does that now. Fixed a bug related to LEAVE command.
5495 * Fixed Remove Channel User payload parsing bug in server's
5496 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5498 * The server's silc_server_save_channel_key now checks also the
5499 global ID list for the channel as it might not be in the local
5500 list. Fixed a bug related to LEAVE command.
5502 * Is this the end of the [<unknown>] buglet that has been lurking
5503 around for a long time? A little for loop fix in server's
5504 silc_server_command_whois_parse that is used by both IDENTIFY
5505 and WHOIS command. At least, this was a clear bug and a cause
5506 of one type of [<unknown>] buglet.
5508 * WHOIS and IDENTIFY commands call the function
5509 silc_server_command_[whois/identify]_check function even if
5510 we are not router server.
5512 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Added --with-gmp configuration option. If set the GMP
5515 is always compiled in the SILC source tree. If not set then
5516 it is checked whether the system has the GMP3 installed. If
5517 it has then the GMP won't be compiled (the system's headers
5518 and library is used), if it doesn't have it then the GMP is
5519 compiled in the SILC source tree.
5521 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Changed RSA private exponent generation to what PKCS #1
5524 suggests. We try to find the smallest possible d by doing
5525 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5526 not security fix but optimization.
5528 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Added new config entry [Identity] to fork the server and run
5531 it as specific user and group. A patch from Bostik.
5533 * Imported Dotconf configuration library into lib/dotconf.
5534 This will be used to create the SILC configuration files later.
5535 It will appear in the distsribution after this commit.
5537 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * A big code auditing weekend happening. Auditing code for
5540 obvious mistakes, bugs and errors. Also, removing any code
5543 Removed files for being obsolete:
5545 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5546 inline in the file lib/silcutil/silcbuffer.h)
5548 o lib/silcutil/silcbufutil.c (the header has inline versions)
5550 Changed code to fix possible error conditions:
5552 o The buffer formatting routines now check that the destination
5553 buffer really has enough space to add the data. This applies for
5554 both buffer formatting and unformatting
5555 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5556 unformatting was changed to accomodate following rules:
5557 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5558 sent to the function while XXX_*STRING will not allocate or copy
5559 the data into the buffer. Instead it sets the pointer from the
5560 buffer into the pointer sent as argument (XXX_*STRING used to
5561 require that the pointer must be allocated already). This change
5562 makes this whole thing a bit more consistent and more optimized
5563 (note that the data returned in the unformatting with XXX_*STRING
5564 must not be freed now). The routines return now -1 on error.
5566 o Tried to find all code that use buffer_format and buffer_unformat
5567 and added return value checking to prevent formatting and
5568 especially unformatting errors and possible subsequent fatal
5571 o Changed ske->x and ske->KEY to mallocated pointers in
5572 lib/silcske/silcske.h. Fixed possible data and memory leak.
5574 o Added return value checking to all *_parse* functions. Fixed
5575 many memory leaks as well.
5577 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5578 so that buffer overflows would not happen. All code now also
5579 checks the return value as it can fail.
5581 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Added reconnection support to server if the normal server looses
5584 its connection to the router (for example if router is rebooted).
5585 The server performs normal reconnection strategy implemented
5586 to the server. Affected file silcd/server.c.
5588 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added new packet type SILC_PACKET_SET_MODE that is used to
5591 distribute the information about changed modes (for clients,
5592 channels and clients channel modes) to all routers in the
5593 network. Updated the protocol specification accordingly.
5595 Added functions into silcd/packet_send.c and
5596 silcd/packet_receive.c: silc_server_send_set_mode,
5597 silc_server_set_mode.
5599 Added new files silcmode.[ch] into lib/silccore that implements
5600 the encoding and decoding of Set Mode Payload. Added new type
5601 SilcSetModePayload. Moved the definitions of different modes
5602 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5604 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Oops, a little mistake in server's connection authentication
5607 protocol. The protocol is not ended with FAILURE but with
5608 SUCCESS if the authentication is Ok. :) Affected file is
5611 * Implemented NICK_CHANGE notify handling in server in the file
5612 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5613 the local clients on the channel. After the changing nickname
5614 in router environment snhould work and the [<unknown>] nickname
5615 should appear no more.
5617 The silc_server_replace_id function that receives the Replace ID
5618 payload now sends the NICK_CHANGE notify type also in the file
5619 silcd/packet_receive.c
5621 * Changed WHOIS and IDENTIFY command to support the maximum amount
5622 of arguments defined in protocol specs (3328 arguments). This
5623 fixed a bug that caused problems when there were more than three
5626 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Added extra parameter, command identifier, to the
5629 silc_client_send_command so that explicit command identifier
5632 Changed that ID list routines uses specific command identifier
5633 when sending WHOIS/IDENTIFY requests to the server so that they
5634 can be identified when the reply comes back.
5636 Affected files lib/silcclient/command.[ch],
5637 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5639 * Added `sender' argument to silc_server_packet_send_to_channel
5640 to indicaet the sender who originally sent the packet to us
5641 that we are now re-sending. Ignored if NULL. Affected file
5642 silcd/packet_send.[ch].
5644 * Added some server statistics support in silcd/server_internal.h
5645 SilcServerStatistics structure and around the server code. Also
5646 send some nice statistics information when client is connecting
5649 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Fixed channel ID decoding in server's JOIN command reply in
5652 silcd/command_reply.c
5654 * Fixed braodcasting of replace ID payload to not to send it if
5655 we are standalone server in silcd/packet_receive.c.
5657 * Fixed all channel message sending routines to not to send
5658 packets to clients that has router set, since they are routed
5659 separately in the same function earlier. Affects file
5660 silcd/packet_send.c and all channel packet sending functions.
5662 * In USERS reply, res_argv[i] are not allocated, the table
5663 is allocated. Thus changed that free the table, not its
5666 * In server's whois_check and identify_check if the client is
5667 locally connected do not send any WHOIS commands - they are not
5670 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Fixed some minor bugs in client when sending WHOIS command. The
5673 arguments was in wrong order.
5675 * Removed statis function add_to_channel from server in
5676 silcd/command.c that was previously used with the joining but
5679 * Tested USERS command in router environment successfully with two
5680 routers, two servers and two clients.
5682 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Reorganized the USERS command and command reply in client library
5685 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5686 When the command is given by user we register a pending command
5687 callback that will reprocess the command after the reply has been
5688 received from the server. When reprocessing the packet we then
5689 display the information. Thus, the USERS information is displayed
5690 now in the command callback instead of in the command reply
5691 callback. The processing of the command is same as previously
5692 when server has sent the command reply in the JOINing process.
5694 * Added to USERS command in silcd/command_reply.c to join the client,
5695 we didn't use to know about, to the channel after we've created
5696 a client entry for it. Also, for clienet we did know already still
5697 check whether it is on the channel or not and add it if not.
5699 * Removed silc_server_command_join_notify as the function and its
5702 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Changed the client's pending command handling to the same as the
5705 server's pending command handling. It is also now possible to
5706 execute command reply functions from other command reply
5707 function as the function callbacks for commands and command
5708 replies are one and same. The pending commands are not static
5709 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5710 in client connection context. Thus, pending commands are server
5711 connection specific as it is convenient.
5713 Changed the function silc_client_command_pending and
5714 silc_client_command_pending_del and added new function
5715 silc_client_command_pending_check. Removed the
5716 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5719 * Added cmd_ident, current command identifier, to the client
5720 connection context in lib/silcclient/client.h to keep track on
5721 command identifiers used in command sending. Client's command reply
5722 function handling now supports the mandatory command identifiers.
5724 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5725 funtions in client to fully support pending command callbacks.
5727 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5728 as one of the arguments to the application in the command reply
5731 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5732 before first releasing SILC but came back. Now it is removed again
5733 and should come back nomore. The FORWARDED flag was used only
5734 by the JOINing procedure by forwarding the command packet to router.
5735 Now, the JOINing procedure has been changed to more generic (due
5736 to various router environment issues) and FORWARDED is not needed
5737 anymore for anything. The protocol specification is yet to be
5740 Now, removed silc_server_packet_forward from server and the flag
5741 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5743 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5745 * Renamed NAMES command to USERS command. The NAMES was named that
5746 due to historical reasons. Now it is renamed. Also, rewrote
5747 parts of the USERS command. The nickname list is not sent anymore
5748 by the server. Only Client ID and mode lists are sent in the USERS
5749 command. Changed this also to the protocol specification.
5751 The client now resolves the names and stuff after it receives
5752 the USERS list from the server when joining to the channel.
5754 * WHOIS and IDENTIFY commands has been changed to support multiple
5755 Client ID's per command. One can now search for multiple users
5756 in the network by sending only one WHOIS or IDENTIFY command.
5757 Changed the code and the protocol specifications.
5759 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5760 uses silc_server_command_whois_parse to parse the request. */
5762 * If normal server, do not parse the WHOIS and IDENTIFY requests
5763 before sending it to the router. Saves some time.
5765 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Fixed JOIN command on client library. Wrong number of arguments
5768 used to crash the client.
5770 * Added silc_server_channel_has_global function to check whether
5771 channel has global users or not.
5773 * Added silc_server_channel_has_local function to check whether channel
5774 has locally connected clients on the channel.
5776 * The silc_server_remove_from_one_channel now checks whether the
5777 channel has global users or not after given client was removed from
5778 the channel. It also checks whether the channel has local clients
5779 on the channel anymore. If it does not have then the channel entry
5780 is removed as it is not needed anymore.
5782 * The silc_server_notify now checks on JOIN notify whether the joining
5783 client is one of locally connected or global. If it is global then
5784 the channel has now global users on the channel and that is marked
5785 to the channel entry. Also, it now saves the global client to
5786 global list who is joining and JOINs it to the channel. This is
5787 for normal server, that is.
5789 Changed silc_server_send_notify_on_channel,
5790 silc_server_packet_relay_to_channel and
5791 silc_server_packet_send_to_channel check if we are normal server
5792 and client has router set (ie. global client) do not send the
5793 message to that client, as it is already routed to our router.
5795 * Implemented LEAVE notify type handling in silc_server_notify
5798 * Tested LEAVE command in router environment successfully. Tested
5799 with two routers, two servers and two clients.
5803 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5805 * Implemented SIGNOFF notify type handling in silc_server_notify
5808 * silc_server_remove_id now removes the client entry from all channels
5809 it has joined and thusly sends SIGNOFF notify type.
5811 * Rewrote the NAMES list generation in server by removing two excess
5812 loops. The lists are created now inside one loop.
5814 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * silc_server_remove_channel_user checks now also global list
5817 for channel and client.
5819 * silc_server_new_channel_user checks now both local and global
5820 list for channel and client. Fixed a bug in client id decoding.
5821 Used to decode wrong buffer.
5823 * silc_server_channel_message checks now both local and global
5824 list for channel entry.
5826 * Tested channel joining (hence JOIN) in router environment
5827 successfully. Tested with two routers, two servers and two
5830 * Tested channel message sending in router environment successfully.
5832 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Added silc_server_save_channel_key into server.[ch] to save the
5835 received channel key in Channel Key payload processing. It is
5836 also used in JOIN command reply handling.
5838 Equivalent function silc_client_save_channel_key added into
5839 client.[ch] into client library.
5841 * Changed JOIN command reply to send information whether the channel
5842 was created or not (is existing already) and the channel key
5843 payload. Changed protocol specs accordingly.
5845 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5846 the request was sent by ID and not by nickname. Crashed on
5849 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5852 now correctly save the received data.
5854 * silc_server_free_sock_user_data now notifies routers in the
5855 network about entities leaving the network.
5857 At the same time implemented functions silc_server_remove_id
5858 and silc_server_send_remove_id to receive and send REMOVE_ID
5859 packets. The packet is used to notify routers in the network
5860 about leaving entities. The ID removed will become invalid in
5863 * Added function silc_idlist_del_server into server. Removes and
5864 free's server entry from ID list.
5866 * silc_server_private_message function now checks, if we are router,
5867 that the destination ID really is valid ID, naturally.
5869 * In router when NEW_ID packet is received (for new client) the
5870 hash of the Client ID is saved in the ID Cache but the
5871 client->nickname is set to NULL, instead of putting the hash
5874 IDENTIFY command now also checks that client->nickname must be
5875 valid. If it is not if will request the data from the server who
5876 owns the client. Added new function
5877 silc_server_command_identify_check.
5879 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5880 to set the command to already allocated Command Payload.
5882 * Tested private message sending in router environment with two
5883 routers, two servers and two clients. Fixed minor bugs and now
5886 * Fixed segfault from client's NAMES command. Used to crash if
5889 * Forwarded packets must not be routed even if it is not destined
5890 to the receiver. Changed server code comply with this.
5892 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Added `require_reverse_mapping' boolean value to ServerParams
5895 structure. If TRUE (not default) the server will require that
5896 the connecting host has fully qualified domain name.
5898 If the reverse mapping is not required and hostname could not be
5899 found the IP address is used as hostname.
5901 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Implemented version string checking to both client and server.
5904 The check is incomplete currently due to the abnormal version
5905 strings used in development version of SILC.
5907 * Changed all command functions in server to use the new
5910 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Changed char *data to unsigned char *data in ID Cache system to
5913 support binary data as ID Cache data. Changed code to support
5914 binary data in lib/silccore/idcache.c.
5916 * Renamed silc_server_packet_relay_command_reply to
5917 silc_server_command_reply as it is normal packet receiving
5918 function. Rewrote the function to accept command replys for
5919 servers and not only for clients.
5921 * Mark remote router always as registered server if we are connecting
5922 to it. Otherwise, commands sent by the router to us are ignored.
5924 * All ID List find routines now returns the ID Cache Entry pointer
5925 as well if requested.
5927 * WHOIS command works now in router environment, tested with two
5928 routers, two servers and two clients.
5930 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5931 in router environment (as it is almost equivalent to WHOIS) but
5932 hasn't been tested thoroughly. Added new functions:
5934 silc_server_command_identify_parse
5935 silc_server_command_identify_send_reply
5936 silc_server_command_identify_from_client
5937 silc_server_command_identify_from_server
5939 * Disabled route cache adding because adding two different ID's with
5940 same IP replaces the old cache entry thus giving wrong route.
5941 The entry->router->connection is always the fastest route anyway
5942 so route cache may not be needed. Of course, new routes maybe
5943 established after receiving the ID when the entry->router->connection
5944 might not be anymore the most optimal.
5946 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Add route cache for received ID for fast routing.
5950 * Added silc_server_packet_route to route received packet on router
5951 that is not destined to us.
5953 * Renamed silc_server_get_route to silc_server_route_get.
5955 * Added id_string and id_string_len fields into SilcServer to
5956 include encoded ServerID for fast comparing without excess
5957 encoding of the ID's.
5959 * Cleaned up WHOIS command on server side. Added following static
5962 silc_server_command_whois_parse
5963 silc_server_command_whois_check
5964 silc_server_command_whois_send_reply
5965 silc_server_command_whois_from_client
5966 silc_server_command_whois_from_server
5968 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5969 arguments in command replies. All command functions should be
5970 updated to use this macro.
5972 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Minor typo fixes on command reply handling on server.
5976 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Added silc_server_command_add_to_channel internal routine to add
5979 the client to the channel after router has created the channel and
5980 sent command reply to the server.
5982 * Added generic silc_server_send_command to send any command from
5985 * Use static buffer with ID rendering instead of duplicating data.
5987 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5989 * Fixed a channel user mode bug when joining to a channel server gave
5990 everybody channel founder rights, oops.
5992 * We mark ourselves as the router of the incoming server connection
5993 if we are router ourselves. This way we can check in some packet
5994 sending functions whether it is locally connected server. For
5995 incoming router connections we put NULL.
5997 * For router sending packets locally means now always sending the
5998 packet cell wide; to local clients and local servers. For normal
5999 server sending packet locally means sending it to only local
6002 * Fixed the JOIN command to really work in router environment. If the
6003 channel is created it is always created by the router. Router is
6004 also responsible of making the initial joining to the channel,
6005 sending JOIN notify to the sending server and distributing
6006 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6007 does not exist server doesn't do anything else but forward the
6008 command to the router which performs everything.
6010 * Added silc_server_send_channel_key function to send the Channel Key
6013 * Added silc_server_create_channel_key to create new channel key. The
6014 channel key is now re-generated everytime someone joins or leaves
6015 a channel, as protocol dictates. Note: channel->key_len is the
6018 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6021 packet_receive.[ch] to separate packet sending and receiving
6022 routines. The server.[ch] now includes everything else including
6023 actual packet processing (writing and reading data) and other
6026 Renamed silc_server_private_message_send_internal to
6027 silc_server_send_private_message. The routine is still though
6028 used only to relay private messages as server does not send
6029 private messages itself.
6031 Renamed silc_server_new_channel to silc_server_create_new_channel
6032 and added new function sicl_server_new_channel that handles the
6033 incoming New Channel packet. Added also new sending function
6034 silc_server_send_new_channel to send New Channel Payload.
6036 * Added new function silc_server_notify to process incoming notify
6037 packet to the server/router. Server may then relay the notify
6038 to clients if needed.
6040 * Added new function silc_server_new_channel_user to process incoming
6041 New Channel User packet. Router will redistribute the packet and
6042 send JOIN notify to its local clients and locally connected servers
6043 if needed. Normal server will send JOIN notify to its local client
6044 on same channel when received this packet. Added also corresponding
6045 sending function silc_server_send_new_channel_user to sent the
6048 * Added boolean route argument to send_notif_to_channel and
6049 packet_send_to_channel functions to attempt to route the packet
6050 if it is TRUE and send only locally if it is FALSE.
6052 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * silc_server_replace_id now broadcasts the received replace ID
6055 packet if it is not broadcast packet already. The router must
6056 broadcast to inform other routers about changed ID.
6058 * Added backpointer to server's router into SilcServer context in
6059 silcd/server_internal.h.
6061 * Fixed silc_server_packet_broadcast to send correct broadcast
6064 * The channel key is now distributed to the local client as soon
6065 as it is received from the router (in router environment) so that
6066 no other packet may be sent for the channel until client has
6069 * silc_server_remove_channel_user now broadcasts the received
6070 Remove Channel User packet if it is not broadcast packet already.
6071 The router must broadcast to inform other routers about removed
6074 * Added users field into SilcPacketContext that is a reference count
6075 of the context. One can increase the reference count by calling
6076 silc_packet_context_dup which is now changed to just increase the
6077 reference count instead of duplicating the data. The reference
6078 count is decresed by calling silc_packet_context_free that will
6079 free the data after the reference count hits zero.
6081 For now on the packet context and everything allocated into it
6082 (including the raw packet from network) must be freed by calling
6083 the new silc_packet_context_free function. Added also new function
6084 silc_packet_context_alloc that must be used now to allocate the
6085 context. This also means that if a routine is asynchronous from
6086 silc_[client/server]_packet_parse_type the packet context must
6087 be duplicated by calling silc_packet_context_dup. Otherwise it
6088 gets free'd after silc_[client/server]_packet_parse_type returns.
6089 Also, one must remember that if packet is duplicated then its
6090 reference count must be decresed by calling the free function as
6091 many times as it was duplicated.
6093 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6094 from both client and server.
6096 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6098 * Made joining to a channel working in router environment.
6100 * Cleaned up JOIN command on server side and create function
6101 silc_server_command_join_channel internal routine to make the
6104 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Changed silc_command_pending list to SilcDList. Also, added
6107 `ident' field to SilcServerCommandPending structure to identify
6108 the reply and to call correct callback.
6110 Added silc_server_command_pending_check function to replace the
6111 corresnponding macro. The silc_command_pending list is not
6114 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6115 to set identifier to previously allocated Command Payload. It
6116 is used to set identifier for command when resending Command
6119 * Added silc_command_payload_encode_payload to encode Command
6120 Payload buffer from SilcCommandPayload structure.
6122 * Added silc_argument_payload_encode_payload to encode Argument
6123 payload buffer from SilcArgumentPayload structure.
6125 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Changed WHOIS command to support router connection on server side.
6128 The whois request is always sent to router unless the server is
6129 standalone server. After server has received the reply from the
6130 router will it send the reply to the client.
6132 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6133 broadcast received broadcast packet. The function is used only
6134 by router. The broadcast packet is always sent to the router's
6137 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6138 render given ID to printable string, for log files for example.
6140 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Made basic router to router connections working. At least they
6143 can now connect to each other but nothing really works the way
6144 they are supposed - yet.
6146 * Added new initiator token to RouterConnection configuration
6147 file in silcd/serverconfig.[ch]. It is used to tell whether we
6148 are the initiator to the remote router or whether we'll expect
6149 the other end to connect.
6151 * Moved registering of listener task to silc_server_init, hence
6152 the server starts listenning as soon as it is run, even if it
6153 does not have connections to other routers. Let's see how well
6156 * Changed default connection retry timeouts for more suitable in
6159 * Removed cipher and such arguments from silc_idlist_add_client
6160 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6161 Added new function silc_idlist_add_data to add the keys and stuff
6164 * Added SilcIDListData structure and added it to SilcClientEntry
6165 and SilcServerEntry as their first field in the structure. This
6166 way we can explicitly cast the ID entries to the SilcIDListData
6167 structure and get common data for the entries. In past, we had
6168 to first check what type of connection it is and then cast it to
6169 correct ID entry type. Now, we can directly cast the opaque
6170 pointer to the SilcIDListData (no matter what ID entry it actually
6171 is) and get the data needed.
6173 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6176 in some circumstances even if threre were timeout tasks, though not
6177 IO tasks, but tasks anyway. Now fixed.
6179 * Defined SilcServerConnection structure to hold connection specific
6180 stuff about directly connected servers and routers. The definition
6181 is currently in silcd/server_internal.h. I thought about having
6182 a bit more important role fro this struct but for now it is used
6183 only when connecting to other server (or router actually).
6185 * Added connecting retry support in server when connecting to
6186 router(s). The retry feature implement exponential backoff
6187 algorithm. Also, added SilcServerParams structure to hold default
6188 parameters for server. For now, it include these retry settings
6189 and are hard coded. After server is moded to be as Silc Server
6190 Library this structure will be more important.
6192 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6194 * Changed client librarys channel->clients table to SilcList and
6195 changed code accordingly.
6197 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Changed client's channel table to SilcList and changed code
6200 accordingly. Also changed SilcChannelClientEntry to include back-
6201 pointer to the channel so that client entry can use that structure
6202 as list as well and we have fast cross-reference to the channel.
6203 This change dramatically decreased the complexity of channel
6204 handling with client entry and vice versa (removed one extra
6205 loop when searching for channel entry from many functions).
6207 * Changed server->sim from table to SilcDList and changed code
6210 * NAMES command can now be used from user interface. It will show
6211 the user list on the channel, neatly.
6213 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6214 Code now saves realname of the user if it becomes available.
6216 * Renamed configure.in to configure.in.pre and made ./prepare
6217 script to automatically add correct version string to
6218 configure.in which it creates from configure.in.pre.
6220 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * NAMES command reply now shows users mode with the nickname when
6225 * Moved silc_client_ch[u]mode[_char] functions from
6226 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6227 place sucks, they are utility functions and should be in some
6230 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6232 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6235 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6239 * Added TRQ (efficient deque and list library) into lib/trq. This is
6240 a very good list library that is currently used in the SILC. Defined
6241 SilcList API over the library because I didn't like the API very
6242 much. See lib/trq/silclist.h for the API and examples of how to
6243 use the API. Fixed various places in the code to use the new
6244 SilcList API. The SilcList is meant for lists that has a structure
6245 already defined as a list. It is not suitable to add just some
6246 context to the list (in TRQ, the context is the list actually).
6248 So, I defined SilcDList that can be used for the purpose where
6249 predefined list structure does not exit. This can be used as
6250 such list. Now some context just can be added to the SilcDList.
6251 Currently this list is not used in the SILC just yet, though there
6252 are a lot places where this can replace dynamically allocated
6253 tables and I will fix these places, later, to use SilcDList.
6254 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6255 and use TRQ internally).
6257 Also fixed some annoying warning messages that the original TRQ
6258 code generated. Also minor changes to TRQ's Makefile.in.
6260 * Added support for querying by Client ID to both WHOIS and
6261 IDENTIFY commands into server, as required by the protocol.
6263 * Removed method function pointers from SilcBuffer structure. They
6264 weren't used to anything and just increased the context size for
6265 no good reason. This change also made silc_buffer_alloc and
6266 silc_buffer_free functions inline functions.
6268 * Disabled command flooding detection support until it's fixed so
6269 that it accepts commands in but does not execute them more than once
6272 * Added silc_net_localhost(), to return local hostname, into
6273 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6274 that must be initialized before calling silc_client_init.
6276 * Added new function: silc_server_send_notify_on_channels to send
6277 notify messages to all channels client has joined. It is assured
6278 that the message is sent only once per client.
6280 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6281 lib/silcutil/silcutil.[ch] as silc_format function. The new
6282 function is generic and is used by server as well, not only by
6283 the logging routines.
6285 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6286 the provided version string was not acceptable. Added new function:
6287 silc_ske_check_version into lib/silcske/silcske.h. The function
6288 must be implemented by the application (client or server) and it
6289 does not reside in the SKE library. The function checks the version
6290 string remote end sent.
6292 * Added back pointers (to opaque context and to SilcSocketConnection)
6293 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6295 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6296 duplicate packet context structure.
6298 * Changed `notify' client operation to send same arguments as client
6299 receives from server except for ID's. ID's are mapped to correct
6300 ID entry and that is returned. Also, if channel entry is not sent
6301 by server but the notify is for channel the channel entry is sent
6302 to application (otherwise application doesn't know that it is for
6303 channel (library gets it from packet's Destination ID)).
6305 * Added silc_client_remove_from_channels into client library to
6306 remove a client from all channels it has joined to. Used when
6307 received SIGNOFF notify from server. Added also new function
6308 silc_client_replace_from_channels to replace old ID entry with
6309 new ID entry on all channels. Used when received NICK_CHANGE
6312 * Fixed ID Cache list handling in silc_idlist_get_client in
6313 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6314 to get (or query) client by ID.
6316 * Updated TODO list.
6318 * Added connection authentication status message defined by the
6319 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6320 support for these into the code in client and server side.
6322 * Added generic function silc_client_send_command to send any command
6323 with variable argument list. Application should use this function
6324 to send commands if the command functions provided by the library
6325 does not suite for the application's user interface needs.
6327 * Added new `failure' client operation. Application is notified about
6328 received failure packet if client is executing a protocol. In this
6329 case the protocol's execution has failed.
6331 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6332 is required by the protocol.
6334 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6335 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6338 * Added status flag to SilcSKE object to indicate realtime status
6339 of the SKE protocol.
6341 * Application receives now exactly same command reply arguments as
6342 the library receives from server. However, if ID is received the
6343 corresponding ID entry is returned to the application (eg. Client
6344 ID is mapped to correct SilcClientEntry entry and that is returned).
6345 Changed command_reply client operation due to this change.
6347 * Changed all ID's in commands and in command replys as ID Payloads.
6348 Change affected both client and server side codes.
6350 All ID's sent in SILC network (with execption of ID's in SILC
6351 Packet header) are sent in ID Payload to support variable length
6354 * Server now notifies nick changes and notifies all clients on
6355 the channels about the new nickname (about the new Client ID,
6358 * Implemented CMODE command to change channel modes. Supports all
6359 channel modes defined by the protocol specs except ban and invite
6360 lists. (Also, private channel key mode is supported but support for
6361 setting private channel key in client is missing, thus, this mode
6362 has no effect on client side (except that server requires that the
6363 client uses private channel key and normal channel traffic does not
6366 Also, invite mode works per se, but INVITE command does not work
6367 yet correctly, so you can set channel as invite only channel but
6368 inviting clients to the channel does not work (it is yet to be
6369 thought what's the best way to do it).
6371 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6372 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6373 Implemented CUMODE command to change user's mode on the channel.
6374 Supports all modes defined by the protocol specs.
6376 * Added NAMES command reply to return users modes on the channel.
6378 * Removed unnecessary and slow ciphers from lib/silccrypt.
6380 * Set SO_KEEPALIVE option to connection sockets by default.
6382 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6384 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6385 redefined the Notify Payload into protocol specs.
6387 * Added silc_id_payload_parse_id to get ID directly from raw
6390 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6393 accept searching by Client ID as well.
6395 * Added support for LEAVE and SIGNOFF notify types in client library.
6397 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6398 to parse ID Payload from raw data.
6400 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Added flags parameter into silc_ske_assemble_security_properties
6403 function in lib/silcske/silcske.[ch].
6405 * Changed notify client operation to fit better for notify messages
6406 sent by server. The notify payload received from server is now
6407 passed to the application (after parsing it to SilcNotifyPayload).
6408 It is application's responsibility to retrieve the arguments
6409 from the payload and show the message the way it wants. The message
6410 sent by server is implementation specific.
6412 * Changed public keys to comply with the protocol specification.
6413 Old public keys are not supported anymore and are not compatible.
6415 * Removed nickname from Channel Payload as the latest draft removed
6416 it. The client must resolve the nickname from the NAMES command
6417 reply received when it joined the channel.
6419 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6421 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Fixed some errors in protocol specification drafts.
6425 * Created lib/silccore/silcnotify.c to implement Notify Payload
6426 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6427 generic payloads described by protocol specifications. The file
6428 includes implementations for ID Payload and Argument Payload.
6430 * Changed Command Payload implementation to use the new Argument
6431 Payload. Changed command_xxxx_payload to command_payload_xxxx
6432 to comply with SILC coding conventions.
6434 * Added suppport for Argument Payload handling in Notify Payload
6435 implementation as protocol requires it. Added the new support
6436 into server and client lib as well.
6438 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Added support for multiple nicknames on same channel. [n] is
6441 added locally to the nickname if there are more than one same
6442 nicknames on the channel.
6444 * Server now sends all nicknames that matched WHOIS request.
6445 Client also shows the list received from server.
6447 * Added TOPIC command to client side. User can now set and show
6448 current topic on channel.
6450 * Added MOTD command to client and server. Also, server sends the
6451 motd when client connects to the server.
6453 * Changed version strings to comply ISO 8601.
6455 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Fixed protocol error handling in client library. It should now
6458 cope even if the SKE fails for some reason.
6460 * Made new protocol specification drafts for submitting to IETF.
6462 * Implemented TOPIC command to server in silcd/command.c.
6464 * Added two new notify types into lib/silccore/silcnotify.h:
6465 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6466 notify nickname change and topic setting/change on a channel.
6468 * API change of command_reply operation in client library. The
6469 application gets now the status type received from server as well.
6471 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6475 * Cras fixed and optimized the packet handling even further and
6476 it should work now. Minor change to the prototype of function
6477 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6479 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Added new function into lib/silcutil/silcschedule.[ch]:
6482 silc_schedule_with_fd to select() a specified fd. The function
6483 returns after timeout expires or data arrives or goes. The
6484 function is used by packet routines to wait that all data is
6485 received from network.
6487 * Fixed data reading from network in lib/silccore/silcpacket.c.
6488 The code now assures that all data is read from the fd and then
6489 continues packet processing. This was a bug fix since the code
6490 used to drop some data in some circumstances.
6492 * Added new function into lib/silcclient/client.[ch]:
6493 silc_client_start_key_exchange to start key exchange after
6494 connection has been established to server. The code internally
6495 now uses this funtion but its main purpose was to provide it
6496 for applications that perform their own connecting. After
6497 application has created a connection it merely calls this
6498 function to start the key exchange between client and server.
6499 The library takes care of everything else after that.
6501 Updated also lib/silcclient/README to explain the usage of
6504 * Do not send to application information that connection has
6505 been established. Application gets notified it by connect
6508 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * Applied cras's patch to add silc_schedule_one function. The
6511 function runs scheduler once and returns.
6513 * Fixed the scheduler after cras messed it up. The timeout
6514 handling works now as it's supposed to work.
6516 * Added into lib/silccore/ silcnotify.h to include notify
6517 message types support. Changed silc_server_send_notify*
6518 functions, in server.[ch], to support those new notify types.
6519 Added the support for the notify types into client library,
6520 as well. Added new notify client operation into ops.h in
6523 * Changed silc_server_packet_send_to_channel to send normal
6524 packets instead of just channel message packets. The function
6525 is now used to send the notify packets to channels. It is not
6526 used to send channel message packets anymore, as server never
6529 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6530 va_arg()s as it seems to require it nowadays. I guess, if SILC
6531 is compiled with older va_arg() the new code should work anyway.
6533 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Splitted core library. Core library (lib/silccore) includes
6536 now only SILC protocol specific core (and common) components.
6537 Created new utility library (lib/silcutil) that includes more
6538 generic purpose stuff. The stuff for util library was taken
6539 from the old core library. This was minor and easy split.
6541 * Created SILC Client Library (lib/silcclient) that includes
6542 implementation of the SILC client without user interface. This
6543 was major move from silc/ directory. The code has been changed
6544 so that it is transparent towards the user interface. The
6545 silc/ directory includes now the same user interface as before
6546 and it uses the new client library. Read lib/silcclient/README.
6547 Basicly, the client library performs everything else related
6548 to SILC except user interface handling. Also, configuration
6549 files are considered to be part of user interface and library
6550 does not handle them.
6552 This change also changed a lot of structures, function naming etc.
6553 Most important change was that SilcClientWindow object was
6554 renamed to SilcClientConnection in the client library. Created
6555 also new file lib/silcclient/ops.h. Also added new files
6556 silc/local_command.[ch] and silc/client_ops.[ch].
6558 All these changes were made to make it easier for user interface
6559 designers to create what ever user interface for the SILC client
6562 It is also expected that the server will be moved to lib
6563 directory as well and SILC Server Library will be created;
6564 sometimes in the future.
6566 * Removed Local commands from lib/silccore/silccommand.h as
6567 they are application specific and new client library does not
6568 handle any of those anymore.
6570 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6571 old client implementation in silc/.
6573 * Added support for callback functions in SILC_LOG_* macros.
6574 Application can now set its own callbacks that will be called
6575 instead of using the default functions that will always print
6576 the debug messages to stderr (or stdout). Also, debugging can
6577 now be disabled by setting silc_debug to FALSE and re-enabled by
6578 setting it to TRUE. Note, that logging will still work even
6579 if debugging is disabled.
6581 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6582 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6583 silc_log_reset_debug_callbacks.
6585 * To enable debugging in silc client one must give now -d
6586 option on command line.
6588 * Changed silc_schedule_init to automatically allocate task queues
6589 if they are not allocated before calling it.
6591 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Added GMP 3.1 into math library.
6595 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6597 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6598 a channel in SILC network. The packet is used by servers and
6599 routers to notify other routers that user has left a channel.
6600 This little feature was missing until now. Added the feature
6601 to protocol specification as well.
6603 Added functions: silc_server_send_remove_channel_user and
6604 silc_server_remove_channel_user into server.[ch].
6606 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6607 lib/silccore/silcpacket.h. However, they are not implemented
6610 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Fixed joining to a channel and sending channel messages
6613 between server and router. The channel message sending should
6614 now work inside a cell.
6616 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Fixed the private message sending between server and router.
6619 The private message sending should now work inside a cell.
6621 * Added silc_server_replace_id into server.[ch] to replace
6622 existing ID in the SILC network.
6624 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6625 and silc_idlist_replace_server_id into idlist.[ch] in server.
6627 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6629 * Fixed the server to server connections. Server can again now
6630 connect to router. Router to router connections probably does
6633 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6635 * Added dynamic protocol registering support. Now protocols can
6636 registered and unregistered on the fly. Patch by cras.
6638 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Added lib/contrib directory to hold routines that some platforms
6641 don't have but are needed by SILC.
6643 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6644 into lin/contrib to provide getopt() and getopt_long() for
6645 those who don't have it.
6647 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Added AWAY command to client. When away message is set and
6650 client receives a private message packet the client automatically
6651 replies to the sender with the away message.
6653 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6654 bug seemed to be the cause of recent problems when compiling
6657 * Added version detection support to SKE protocol specification
6658 and added the new changes to the SKE implementation as well.
6659 There were other minor changes in the SKE protocol as well.
6661 Many changes in lib/silcske/silcske.[ch] and in
6662 lib/silcske/payload.[ch].
6664 * Added ^U functionality, clear input line. Patch from cras.
6666 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Mainly small bugfixes on core library. Fixed some debugging
6669 logging and buffer overflow in silclog.c.
6671 * Updated config.sub and config.guess on the distribution tree.
6673 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Added command lagging support in server. Client may execute
6676 commands now only once in two seconds.
6678 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Optimized packet reception. MAC computation and checking is now
6681 also more optimized. A lot previously duplicated code is now
6682 used as generic by both client and server.
6684 * Fixed key pair generation in clientutil.c
6686 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6688 * Added into lib/silccore/silcbufutil.[ch] new function;
6689 silc_buffer_realloc.
6691 * Moved generic packet sending/encryption functions to
6692 lib/silccore/silcpacket.[ch] from client and server. Some
6693 rewriting of the functions.
6695 * Moved all generic packet reception/decryption functions to
6696 lib/silccore/silcpacket.[ch] from client and server. The
6697 packet processing is now much cleaner in both client and server.
6698 These were major changes in both client and server.
6700 * Created many common functions in server to do packet sending.
6701 Previously code were duplicated a lot, this has been removed
6704 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6706 * Rewrote major parts of the ID cache system. Don't know
6707 whether it is better now or not but at least the API is more
6710 * Major rewrite on ID cache stuff on client because of the ID
6711 cache API changes. Added idlist.c to client.
6713 * Also major rewrite on ID cache stuff on server as well.
6714 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6715 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6716 in hand, instead they are all put into the ID cache system now.
6717 All server_idlist_* routines uses ID cache now instead of
6718 traversing its own lists (those lists does not exist anymore).
6719 SilcIDList though still exists. Also, SilcXXXEntry's are
6722 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Finally made the SKE implementation compliant to the protocol
6725 specification. All mp integers are now binary encoded as
6726 opposed being HEX encoded.
6728 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6731 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6732 functions: silc_[encode/decode]_pem. Also added function
6733 silc_encode_pem_file to PEM encode with newlines ('\n') for
6736 * SILC public keys are now encoded either PEM or binary. Same
6737 option is for private keys as well. By default private keys
6738 are binary encoded and public keys PEM encoded. Silly HEX
6739 encoding were removed.
6741 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6742 function to create fingerprints.
6744 * Fixed a bug in SHA1; does not change the original data anymore.
6746 * Partly implemented INFO command on client and server side.
6747 Fixed CLEAR command. Changes to SERVER command; show current
6748 server(s) when giving command without arguments. Added
6749 VERSION command to client.
6751 * Added check to server that unregistered connections cannot
6752 execute commands (unless it is specificly allowed).
6754 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Fixed screen refresh.
6758 * Fixed channel joining bug from client. On some circumstances
6759 client tried to join to a channel it had already joined.
6761 * Added public key verification process into client's protocol.c.
6762 The client now verifies the public key from user and saves
6763 it into ~./silc/serverkeys/ directory.
6765 Added into: clientutil.[ch]: silc_client_verify_server_key.
6767 * Changed SKE protocol's silc_ske_initiator_finish function
6768 to accept callback function that verifies the received public
6769 key. Removed old silc_ske_verify_public_key function.
6771 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6774 silc_pkcs_private_key[_data]_set.
6776 * Made the password and public authentication more cleaner in
6777 server's protocol.c.
6779 * Removed historic and obsolete protocol `channel_auth' from
6780 both client and server.
6782 * Removed wrong way of sending command status messages from
6783 server to client in server's command.c. The old way violated
6784 protocol specification.
6786 Changes to silccore/silccommand.[ch]: removed
6787 silc_command_encode_status_payload -> not needed anymore,
6788 changed silc_command_encode_payload_va to accept extra
6789 argument on variable argument list. The argument type must
6790 now be provided to the function. Also, added new function:
6791 silc_command_encode_reply_payload_va which is same as
6792 normal command_encode_payload_va except command status type
6793 is provided as extra argument.
6795 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Added ~./silc directory handling. The directory includes the
6798 public and private keys for the client.
6800 Added silc_client_check_silc_dir, silc_client_create_identifier
6801 and silc_client_load_keys.
6803 * Implemented SILC protocol compliant public key. Added public
6804 and private key saving to and loading from files.
6806 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6807 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6808 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6809 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6810 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6812 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6813 silc_pkcs_load_[public/private]_key.
6815 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Added silc_server_get_route (route.[ch]) to get connection
6818 data for the fastest route for given ID.
6820 * Implemented INVITE command on client and server. The command
6821 were re-defined in the SILC Protocol Specification and the
6822 implementation now complies with the specification.
6824 * Implemented PING command on client and server.
6826 * Implemented NAMES command on client and server. The server side
6827 supports currently only normal server not router server yet.
6828 Some changes to NAMES definition in SILC protocol specification.
6830 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Implemented LEAVE command on client and server.
6834 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6835 again. This change was made to the protocol as well. Server
6836 should not violate the protocol specification anymore.
6838 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6841 was tested. SOCKS4 was not but should work anyway.
