1 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed a crash in server related to channel announcements.
4 Affected file silcd/server.c.
6 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
8 * Fixed memory leaks in silc_server_create_new_channel*
9 functions. Affected file silcd/server.c.
11 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
12 which ID was changed. This way the router will send the
13 user list for the channel again, and server won't be in
14 desync in some rare circumstances. Affected file is
15 silcd/packet_receive.c.
17 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Check for NULL socket pointer in the function
20 silc_server_packet_send_to_channel_real. Affected file
23 * Fixed the BAN notify handling to correctly remove ban
24 list. Affected file silcd/packet_receive.c.
26 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
28 * Fixed some header addition to Toolkit distribution in
29 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
31 * Added lib/silcclient/client_ops_example.h as an template
32 file for application programmers to quickly start using
33 the SilcClientOperation functions in their application.
34 Updated the lib/silcclient/README as well to tell about this
35 nice file made available.
37 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
39 * Call silc_server_remove_from_channels when removing client
40 entry when NO_SUCH_CLIENT_ID was received. Affected file
41 is silcd/command_reply.c.
43 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Added server & router operator statistics updating. Affected
46 file silcd/packet_receive.c and silcd/command.c.
48 * Fixed the SERVER_SIGNOFF notify handling on normal server
49 not to save the history information for clients. Same was
50 fixed earlier in remove_clients_by_server function, but not
51 here. Affected file silcd/packet_receive.c.
53 * Raised the default connection-retry count from 4 to 7 in
54 server. Affected file silcd/server.h.
56 * Cancel any possible reconnect timeouts when we start the
57 key exchange. Affected file silcd/server.c.
59 * Do not reconnect on connection failure when SCONNECT was
60 given. Affected files silcd/server.[ch].
62 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
64 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
66 * Fixed the NICK command to always give the unformatted
67 nickname to the one giving the NICK command. If unformatted
68 nickname is cached already it will be formatted and the
69 local entry will always get the unformatted nickname.
70 Affected file lib/silcclient/idlist.c.
72 * Fixed some double frees from client library commands.
73 Affected file is lib/silcclient/command.c.
75 * Fixed CUMODE command in server to assure that no one can
76 change founder's mode than the founder itself, there was a
77 little bug. Affected file silcd/command.c.
79 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Removed the SilcClientCommandDestructor from the client
82 libary, it is not needed anymore. Affected files are
83 lib/silcclient/silcapi.h, command[_reply].[ch],
84 client_notify, idlist.c.
86 * Fixed GETKEY command to first resolve client, and then
87 resolve the server only if the client was not found, instead
88 of resolving both at the same time. Affected file is
89 lib/silcclient/command.c.
91 * Added silc_client_start_key_exchange_cb and lookup the
92 remote hostname and IP address before starting the key
93 exchange with server. The affected file is
94 lib/silcclient/client.c.
96 * The server's public key is now saved using the IP address
97 of the server and not the servername for the filename.
98 The hostname public key filename is checked as an fall back
99 method if the IP address based filename is not found.
101 Fixed the GETKEY command to save the fetched server key
104 Print the remote server's hostname now when new key is
105 received during connection process. Affected file is
106 irssi/src/silc/core/client_ops.c.
108 * Return always our own public key to the client if it asks
109 for it with GETKEY command. Affected file silcd/command.c.
111 * Removed the use_auto_addr variable from default config
112 file since it was in wrong section. Affected file is
115 * Fixed TOPIC_CHANGE notification to not route it when it
116 was sent using silc_server_send_notify_to_channel function.
117 Affected file silcd/command.c.
119 * Fixed silc_server_send_notify_kicked to send the kicker's
120 Client ID also, it was missing. Affected files are
121 silcd/command.c, silcd/packet_send.[ch].
123 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
125 * Do not save client history information in SERVER_SIGNOFF.
126 Fixes the bug in normal server that it does not detect
127 the client becoming valid after the server becomes back
128 online. Affected file silcd/server_util.c.
130 * Added `sock_error' field into the SilcSocketConnection
131 context. When error occurs during socket operation (read
132 or write) the error is saved. Added also new function
133 silc_socket_get_error to return human readable socket error
134 message. Affected files are lib/silcutil/silcsockconn.[ch],
135 lib/silcutil/unix/silcunixsockconn.c, and
136 lib/silcutil/win32/silcwin32sockconn.c.
138 * The server now prints the socket error message in the
139 signoff for client. Affected file silcd/server.c.
141 * Fixed the `created' channel information sending from router
142 to server in JOIN command. Checks now whether the channel
143 really was created or not and set it according that.
145 Fixed the JOIN command to use the client entry's current
146 ID during the joining procedure instead of the one it sent
147 in the command (it is checked though), since it can change
148 between the packet processing and command processing, and
149 would just case unnecessary pain in the client end. Affected
150 file silcd/command.c.
152 * Fixed a channel key payload sending to use correct channel
153 ID when the server was forced to change the channel's ID by
154 router. Router sent the key payload with the old Channel ID.
155 Affected file silcd/packet_receive.c.
157 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
159 * Call silc_server_save_channel_key only if the key payload
160 was provided in the JOIN command's command reply. Affected
161 file silcd/command_reply.c.
163 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
165 * Fixed silc_mp_sizeinbase to return the value correctly with
166 MPI. Affected file lib/silcmath/mp_mpi.c.
168 * Fixed the stop_server signal to correctly stop the scheduler
169 and gracefully stop the server when SIGTERM or SIGINT signals
170 are received. Affected file silcd/silcd.c.
172 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
174 * Simple handling of TERM and HUP signals. Also added some log
175 flushing call around. Affected file is
178 * Fixed small bugs in silclog.c. Now buffering output will take
179 effect after 10 seconds since startup: This will ensure that
180 no important startup messages are lost. Also output redirection
181 will preserve original format ([Date] [Type] message).
182 Affected file is lib/silcutil/silclog.c.
184 * Added two options to the config file, in the logging section:
185 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
186 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
188 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
190 * Do not print the warning about log files not being initialized
191 more than once to avoid excess logging. Affected file is
192 lib/silcutil/silclog.c.
194 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
195 the SIM copying in make install in Makefile.am.pre.
197 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
199 * Rewritten silclog APIs. Globally interesting changes follows:
200 silc_log_set_files() changed to silc_log_set_file().
201 silc_log_set_callbacks() changed to silc_log_set_callback().
202 ROBOdoc documented silclog header file.
203 SilcLogCb now returns bool to wether inihibit the default
204 handler or not (to keep the old behaviour return always TRUE).
205 The new APIs should also fix the problem of the
206 silcd_error.log file that was written in the current directory.
209 Log files streams will remain opened after silc_log_set_file()
210 call, means less CPU usage notably on high traffic servers.
211 File streams are now full buffered, and flushed to the disk
212 every 5 minutes, lesses HD activity and CPU usage.
213 Messages can be redirected, allowing admins to configure
214 one single logfile for all server messages.
215 the silc_log_quick global variable to activate fast-logging.
216 Affected files lib/silcutil/silclog.[ch]
218 * Changed some code to conform new silclog APIs. Affected
219 files are doc/example_silcd.conf.in, silcd/server.c
220 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
223 * Fixed a memory leak that could occur in some situations.
224 Affected file silcd/serverconfig.c.
226 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Added the silc_client_del_client to remove the client from
229 all channels as well. Affected file lib/silcclient/idlist.c.
231 * Fixed the client library to correctly remove the client
232 from all channels when the client entry is being destroyed.
233 Affected file lib/silcclient/client_notify.c, command.c.
235 * Added auto-nicking support to the client library. If the
236 applicatio now sets client->nickname it will be sent to the
237 server after connecting by the library. This way for example
238 SILCNICK (or IRCNICK) environment variables will have effect
239 and always change the nickname automatically to whatever
240 it is wanted. Affected file lib/silcclient/client.[ch].
242 * Renamed silc_server_command_bad_chars to the
243 silc_server_name_bad_chars and moved it to the
244 silcd/server_util.[ch]. Added also new function
245 silc_server_name_modify_bad to return nickname that
246 includes bad characters as new nickname without those
247 bad characters. This check and modify is now used in
248 silc_server_new_client when the username is initially set
249 as nickname, so it must be checked to be valid nickname.
250 Affected file silcd/packet_receive.c.
252 * The nickname length is now taken from the packet for real
253 and not trusted to strlen() since it clearly can return
254 wrong length for nickname including bad characters. This
255 also applies to channel names. Affected file silcd/command.c.
257 * Removed the lib/silcsilm/modules directory. Modules are now
258 compiled into the lib/silcsim. Fixed the copying of the
259 modules to follow symbolic links in Makefile.am.pre.
261 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Fixed silc_string_regexify list creation. Fixes bugs with
264 BAN and INVITE commands in server. The affected file is
265 lib/silcutil/unix/silcunixutil.c.
267 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
269 * Removed the command destructor entirely from the server's
270 command and command reply routines. It is not needed, and
271 its usage was buggy and caused crashes. Affected files are
272 silcd/command[_reply].[ch].
274 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
276 * Cancel protocol and NULL sock->protocol if timeout
277 occurred during protocol. Affected file silcd/server.c.
279 * Cancel protocol timeouts always before calling the final
280 callback, to assure that after final callback is called
281 no other state will be called for the protocol anymore.
282 Affected file silcd/protocol.c.
284 * Print error log if incoming connection configuration could
285 not be found. Affected file silcd/server.c.
287 * Fixed JOIN command to correctly save the founder mode
288 to the client on normal SILC server, when the channel
289 was created by the router. Affected file silcd/command.c.
291 * Fixed LIST command (hopefully) to send correct reply
292 packets. Affected file silcd/command.c.
294 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
296 * The silc_packet_receive_process now returns FALSE if the
297 read data was invalid packet, and TRUE if it was ok.
299 The server now checks that if unauthenticated connection
300 sends data and its processing fails the server will close
301 the connection since it could be a malicious flooder.
303 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
305 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
307 * Make sure the warning about error opening a log file is
308 printed only once and not everytime it fails (produces
309 too much useless log). Affected file lib/silcutil/silclog.c.
311 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
313 * Made the silc_server_daemonise() function more readable.
314 Affected file silcd/server.c.
316 * Pid file is now optional, the user may comment it out from
317 the config file. Removed define SILC_SERVER_PID_FILE, we
318 don't need a default any longer. Affected file
319 configure.in.pre, lib/Makefile.am.pre.
321 * Make some use of the pid file. The server now dies at startup
322 if it detects a valid pid file on his path. The server would
323 die anyway in this circumstance, because of the bind() failure.
324 Affected file silcd/silcd.c.
326 * No longer compiling lib/dotconf.
328 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Fixed JOIN command parsing not to crash. Affected file
331 lib/silcclient/command.c.
333 * Fied the NICK_CHANGE notify to add the new client entry
334 even it is resolved. This removes an <[unknown]> nick
335 thingy bug in the client. Affected file is
336 lib/silcclient/client_notify.c.
338 * Do not try to allocate 0 bytes (efence does not like it)
339 in lib/silccore/silccomand.c when encoding payload.
341 * Do not take IRCNICK as nickname in Irssi SILC client since
342 it is not possible to set nickname before hand connecting
343 the server (TODO has an entry about adding auto-nicking
346 * Changed the silc_server_command_pending to check whether
347 there already exists an pending entry with the specified
348 command, command identifier and pending callback. This is
349 to fix IDENTIFY and WHOIS related crashes that may register
350 multiple pending commands with same identifier. Affected
351 file silcd/command.c.
353 * Fixed the server to reconnect to the router even if it
354 was already reconnecting and EOF was received. This to
355 fix a possibility that the server wouldn't ever try to
356 auto-reconnect to the router. Affected file silcd/server.c.
358 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Fixed the server's password authentication to use the
361 length of the locally saved password, and not the one
362 sent in the packet. Affected file silcd/protocol.c.
364 * Fixed same password authentication problem in the
365 Authentication Payload handling routines in
366 lib/silccore/silcauth.c.
368 * Yet another password authentication problem fixed with
369 channel password handling in silcd/command.c.
371 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
373 * If first character of string in silc_parse_userfqdn is '@'
374 then do not parse it. Affected file is
375 lib/silcutil/silcutil.c.
377 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
379 * Fixed minor bug in IDENTIFY command reply sending, which
380 caused various weird problems during JOIN when it was
381 resolving names for users. Affected file silcd/command.c.
383 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
385 * Fixed the IDENTIFY command reply sending to chech better valid
386 clients. It was possible to send incomplete list of replies.
387 Affected file silcd/command.c.
389 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
391 * Added silc_client_command[s]_[un]register functions now to
392 dynamically register the commands in client library. Removed
393 the static table of commands. This allows the client library
394 to call commands without causing the application to know about
395 what commands library has called.
397 Removed the INFO command reply kludge to detect when the command
398 was called by library. Now library use its own command reply
399 function for INFO command.
401 Added function silc_client_command_call to call a command.
402 Application can use it to call command, not access the structure
405 Now all commands that are sent by the client library (not
406 explicitly sent by application) use own command reply functions.
408 Affected files around lib/silcclient/ and in
409 irssi/src/silc/core/.
411 * Fixed the WHOIS command reply sending to chech better valid
412 clients. It was possible to send incomplete list of replies.
414 Fixed the WHOIS and IDENTIFY to send the request to router
415 if normal server did not do it and did not find any results.
417 Affected file silcd/command.c.
419 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
421 * Moved the internal data from SilcClient context into its
422 own file, not accesible to application. Affected files
423 lib/silcclient/client.h and lib/silcclient/client_internal.h,
424 and other files in client library.
426 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Added doc/examples installation target in Makefile.am.pre.
431 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
433 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
434 commands the found client entry will be removed from the
435 cache, after notifying application about the error. Affected
436 file lib/silcclient/command_reply.c.
438 * Changed the /MSG to check for exact nickname user gave, and
439 not let `nick' match `nick@host' if it is only one found. Now,
440 user must type the exact nickname (like nick@host2) even if
441 there are no more than one same nicks found. This is to avoid
442 a possibility of sending nickname to wrong nickname since
443 `nick' could match `nick@host'. Affected file is
444 irssi/src/core/silc-servers.c.
446 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
448 * Do not print "you are now server operator" or similar when
449 giving /away command. Affected files are
450 irssi/src/silc/core/client_ops.c, silc-servers.h.
452 * Made the silc_server_command_pending_error_check to send
453 the same command reply payload it received back to the
454 original sender of the command. This way all arguments
455 that was received by the server will be received by the
456 client too. Affected file silcd/command.c.
458 * Added the silc_idcache_add to return the created cache entry
459 to a pointer. Affected file lib/silccore/silcidcache.[ch].
461 * Add global clients to expire if they are not on any channel.
462 This is because normal server will never know if they signoff
463 if they are not on any channel. The cache expiry will take
464 case of these entries. This is done by normal servers only.
465 The affected files are silcd/command_reply.c,
466 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
468 * If server receives invalid ID notification for WHOIS or
469 IDENTIFY and the ID exists in the lists, it is removed.
470 Affected file silcd/command_reply.c.
472 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
473 in client then client entry that it matches is searched and
474 the nickname is printed on the screen for user. Affected
475 file irssi/src/silc/core/client_ops.c.
477 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
479 * Use cache entry expire time in the LIST command reply to
480 purge old entries from the cache after the LIST command
481 reply has been received. This way we don't have non-existent
482 entries in the cache for too long. Affected file is
483 silcd/command_reply.c.
485 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
487 * If we are normal server, and we've not resolved client info
488 in WHOIS or IDENTIFY from router, and it is global client,
489 we'll check whether it is on some channel. If it is not
490 then we cannot be sure about its validity and will resolve it
491 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
492 file silcd/command.c.
494 * Search channel by name (if possible) rather than by ID
495 in IDENTIFY command's command reply. Affected file is
496 silcd/command_reply.c.
498 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
500 * Distribute to the channel passphrase in CMODE_CHANGE notify.
501 Updated specs and implemented it. Affected file silcd/command.c,
502 silcd/packet_send.c and silcd/packet_receive.c.
504 * Implemented the <founder auth> payload handling in the JOIN
505 command. If provided all conditions for channel joining
506 except requirement to provide correct passphrase can be
507 overrided by the channel founder. Updated the protocol specs.
508 Affected file silcd/command.c.
510 Added support for founder auth in JOIN command in client
511 library. Fixed the parsing of the JOIN command now to support
512 all options as they should be. The affected file is
513 lib/silcclient/command.c.
515 * Optimized the WHOIS and IDENTIFY commands to send the request
516 to router only if it includes nicknames or other names. If
517 they include only IDs then check the local cache first before
518 routing. Affected file is silcd/command.c.
520 * Added channels topic announcements. Affected file is
521 silcd/packet_receive.c and silcd/server.c.
523 * Fixed the silc_server_send_notify_topic_set to really destine
524 the packet to channel. Affected file silcd/packet_send.c.
526 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
527 library. Affected file lib/silcclient/client_notify.c.
529 * Added UMODE announcements. Affected file silcd/server.c.
531 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
533 * Memory leak fixes in:
535 lib/silcutil/silcsockconn.c
536 lib/silcske/silcske.c
539 lib/silccrypt/silcpkcs.c
540 lib/silccore/silccommand.c
541 lib/silccore/silcidcache.c
546 * ROBOdoc documented the lib/silcske/groups.h file and a
547 bit changed the interface for better.
549 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
551 * Update the client entry context in the ID cache after
552 nick change. Affected file lib/silcclient/command.c.
553 Fixes the CUMODE command when regaining founder privileges,
554 and a little WHOIS problem.
556 * Fixed silc_net_gethostbyname to correctly call the
557 inet_ntop. Affected file lib/silcutil/silcnet.c.
559 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
561 * Added IPv6 support checking to the configure.in.pre, added
562 also --enable-ipv6 option to override the check. Affected
563 file configure.in.pre.
565 * The silc_thread_create now calls the start function
566 directly if threads support is not compiled in. Removes

582 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
583 routines. Added silc_net_is_ip[4/6]. Affected file is
584 lib/silcutil/unix/silcunixnet.c. All routines that take
585 address as argument now supports both IPv4 and IPv6 addresses.
587 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
589 * Fixed LIST command reply sending in server. Affected file
592 * Server now sends the kicker's client ID in the KICK notify
593 to the kicked client. Affected file silcd/command.c.
595 * The client library now parses the kickers client ID and
596 UI displays it. Affected files lib/silcclient/client_notify.c
597 and irssi/src/silc/core/silc-channels.c, module-formats.c.
599 * Made all payload parsing function prototypes consistent.
600 They all take now const unsigned char * and uint32 pair as
601 the payload data instead of SilcBuffer. Changes all around
602 the source tree. Other unsigned char* -> const unsigned char*
603 changes around the tree as well.
605 * Optimized SFTP client and server packet sending not to
606 allocate new buffer for each packet but to recycle the
607 first allocated buffer. Affected files are
608 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
610 * Optimized the SFTP client to use SilcList instead of
611 SilcDList for requests, because it is faster. Affected file
612 is lib/silcsftp/sftp_client.c.
614 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
615 into lib/silccore/silcid.[ch].
617 Renamed silcpayload.[ch] into silcargument.[ch].
619 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
621 * If client entry is deleted with active key agreement
622 session, abort the session.
624 The silc_client_abort_key_agreement now calls the completion
625 callback with new SILC_KEY_AGREEMENT_ABORTED status.
627 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
630 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Don't use __restrict in older GCC's. Affected file is
633 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
635 * silc_net_localhost now attempts to reverse lookup the
636 IP/hostname. Affected file lib/silcutil/silcnet.c.
638 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
639 command. It can be used to gain founder privileges at
640 the same time when joining the channel.
642 Defined that the SILC_NOTIFY_TYPE_KICKED send the
643 kicker's client ID as well. Updated protocol specs.
645 Defined that the server must send SILC_COMMAND_IDENTIFY
646 command reply with error status to client who sent
647 private message with invalid client ID.
649 Updated the protocol specification.
651 * Added silc_server_send_command_reply to send any
652 command reply. Affected file silcd/packet_send.[ch].
654 * Added silc_id_payload_encode_data to encode ID payload
655 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
657 * The server now send IDENTIFY command reply with error
658 status if client ID in private message is invalid. Affected
659 file silcd/packet_receive.c.
661 * Save the server key file with server's IP address in
662 the filename instead of hostname. The affected file is
663 irssi/src/silc/core/client_ops.c.
665 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
667 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
670 * Added libtool support for compiling shared objects in
671 lib/silcsim. Affected file configure.in.pre and
672 lib/silcsim/Makefile.am. Original patch by cras.
674 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
676 * Pid file configuration, and server's config file fixes
677 patch by toma. Updated CREDITS file.
679 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
681 * Fixed silc_client_channel_message to not try to decrypt
682 the message twice if it resolved the destination client
683 information. This could cause of dropping one channel
684 message. Affected file lib/silcclient/client_channel.c.
686 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
688 * Added silc_client_run_one into lib/silcclient/silcapi.h and
689 lib/silcclient/client.c. This function is used when the SILC
690 Client is run under some other scheduler, or event loop or
691 main loop. On GUI applications, for example this may be
692 desired to used to run the client under the GUI application's
693 main loop. Typically the GUI application would register an
694 idle task that calls this function multiple times in a second
695 to quickly process the SILC specific data.
697 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
699 * Fixed silc_server_drop() for dropping the supplementary
700 groups as well, this could cause a security hole on some
703 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
705 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

709 to run server on foreground. A patch by debolaz.
710 Affected files silcd/server.c, silcd/silcd.c.
712 * Fixed MOTD to return the MOTD file server name. Affected
713 file silcd/command.c.
715 * Added INFO command reply handling to the Irssi SILC Client.
716 Affected file irssi/src/silc/core/client_ops.c.
718 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
720 * Fixed the silc_idcache_list_* routines to really support
721 the dynamic list. Fixes a crash. Affected file is
722 lib/silccore/silcidcache.c.
724 * Fixed the LIST command reply to really call LIST command's
725 pending callbacks. Affected file silcd/command_reply.c.
727 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Update conn->local_entry->nickname after giving NICK
730 command. Affected file lib/silcclient/command.c.
732 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
734 * Added the [pid] option to the silcd configuration file
736 Affected files: serverconfig.[ch] and silcd.c
738 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
740 * Save fingerprint in WHOIS command reply in server.
741 Affected file silcd/command_reply.c.
743 * Fixed NICK commands pending callback registration.
744 Affected file lib/silcclient/command.c.
746 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
748 * Use ++server->cmd_ident when sending commands in server,
749 instead of random number. Affected file silcd/command.c.
751 * Fixed GETKEY command reply to call actually GETKEY pending
752 command callbacks. Affected file silcd/command_reply.c.
754 * A bit stricter check for nicknames. Check for same nickname
755 in NICK command also. Affected file silcd/command.c.
757 * Do not call INFO command everytime client ID changes, only
758 during first connecting. Affected file lib/silcclient/client.c.
760 * Set the new nickname only after successful command reply for
761 NICK command is returned by server. Affected file
762 lib/silcclient/command.c.
764 * Remove nicknames from nicklist during server_signoff notify.
765 Should fix /NAMES bit more. The affected file is
766 irssi/src/silc/core/silc-channels.c.
768 * Added `fingerprint' field to the SilcIDListData in the
769 silcd/idlist.h to hold the fingerprint of the client's
772 Send the fingerprint of the client's public key in WHOIS
775 Affected files silcd/command.c, and silcd/idlist.[ch].
777 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
778 create fingerprint from given data.
780 * Show the fingerprint of the client's public key in WHOIS.
781 Affected files irssi/src/module-formats.[ch] and
782 irssi/src/silc/core/client_ops.c.
784 * Format the multiple same nicknames also during JOIN and
785 NICK_CHANGE notifys. Affected file is
786 lib/silcclient/client_notify.c.
788 * Do not print error on screen for invalid private message
789 payload since it can come if someone is sending private
790 messages with wrong key. Affected file
791 lib/silccore/silcprivate.c.
793 * Fixed multiple concurrent /PING crash. Affected file
794 lib/silcclient/command.c.
796 * Changed the wrong ID encoding. All IP addresses must be
797 in MSB first order in encoded format. They were encoded
798 wrong and was in LSB format. Affected files are
799 silcd/serverid.c, lib/silcutil/silcutil.c.
801 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
803 * Call the `connect' client operation through the scheduler
804 in case of error. Affected file lib/silcclient/client.c.
806 * Call the `failure' client operation even if the error
807 occurred locally during a protocol. Affected file is
808 lib/silcclient/protocol.c.
810 * Added support of sending LIST command to router from normal
811 server. This way normal server can get list of all channels
812 in the network too. Fixed the channel list sending in the
813 server too. Affected files are silcd/command.c, and
814 silcd/command_reply.[ch].
816 * Added silc_server_update_channels_by_server and
817 silc_server_remove_channels_by_server. They are used during
818 disconnection of primary router and in backup router protocol.
819 Affected file silcd/server_util.[ch], silcd/server.c and
820 silcd/server_backup.c.
822 * Fixed channel adding to global list in IDENTIFY command
823 reply in server. Affected file silcd/command_reply.c.
825 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
827 * If the incoming packet type is REKEY or REKEY_DONE process
828 that packet always synchronously. Fixes yet another MAC
829 failed error on slow (dialup) connections. Affected file
830 lib/silcclient/client.c and silcd/server.c.
832 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Call check_version SKE callback for initiator too. Affected
835 file lib/silcske/silcske.c.
837 * Implemented fix for security hole found in the SKE that was
838 fixed in the specification few days back; the initiator's
839 public key is now added to the HASH value computation.
840 Added backwards support for the old way of doing it too, for
841 old clients and old servers. Affected file is
842 lib/silcske/silcske.c.
844 * Enabled mutual authentication by default in SKE. If initiator
845 is not providing mutual authentication the responder will
846 force it. This will provide the proof of posession of the
847 private key for responder. The affected files are
848 lib/silcclient/protocol.c and silcd/protocol.c.
850 * Do not cache anymore the server's public key during SKE.
851 We do mutual authentication so the proof of posession of
852 private key is done, and if the server is authenticated in
853 conn auth protocol with public key we must have the public
854 key already. Affected file silcd/protocol.c.
856 * Added new global debug variable: silc_debug_hexdump. If
857 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
858 file lib/silcutil/silclog.[ch].
860 * Fixed compilation warning due to char * -> const char *.
861 Affected files lib/silcutil/silcnet.h, and
862 lib/silccore/silcauth.[ch].
864 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
866 * Fixed CMODE command when new channel key was created. If
867 the creation failed the old key was removed. Next time giving
868 same command would crash the server since the old key was
869 freed already. Affected file silcd/command.c.
871 * Fixed the silc_server_announce_get_channels to not crash
872 on reconnect. Affected file silcd/server.c.
874 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
876 * Added silc_log_set_debug_string function to set a regex
877 string to match for debug output. Only the function names,
878 or filenames matching the given debug string is actually
879 printed. This way it is possible to filter out those debug
880 strings that user is not interested in.
882 Fixed a bug in silc_string_regexify.
884 Affected files lib/silcutil/silclog.[ch], and
885 lib/silcutil/unix/silcunixutil.c.
887 * Changed the -d options in both server and Irssi SILC client
888 to take the debug string as argument. Affected files
889 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
891 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Added silc_hash_babbleprint to create a Bubble Babble
894 Encoded fingerprint. The encoding is developed by Antti
895 Huima (draft-huima-babble-01.txt), and it creates human
896 readable strings out of binary data. Affected file
897 lib/silccrypt/silchash.[ch].
899 * Print the babble print now in addition of fingerprint as well
900 in Irssi SILC client. Affected files are
901 irssi/src/fe-common/silc/module-formats.[ch],
902 irssi/src/fe-common/silc/core/client_ops.c.
904 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
906 * Fixed a security problem found in SKE. The initiator's
907 public key too is now added to the HASH hash value creation
908 which is signed by the responder to create the SIGN value.
909 This will prevent anyone in the middle to lie to the responder
910 about the initiator's public key. If this is done now, the
911 man in the middle will get caught. Updated the protocol
914 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
916 * Better installation directory handling. Configure module
917 paths and other paths automatically to example_silc* files
918 in doc/. A patch by toma.
920 * Fixed compiler warning from MPI library, and from SILC RNG.
923 * Added SILC_SERVER_PID_FILE to define the pid file for server.
924 It can be configured with ./configure. A patch by toma.
926 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Find correct make to use in prepare-clean. A patch by
929 toma. Affected file prepare-clean.
931 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
933 * Added irssi variables use_auto_addr, auto_bind_ip,
934 auto_bind_port and auto_public_ip.
936 * Changed the interface for silc_client_send_key_agreement
937 in lib/silcclient/silcapi.h
941 irssi/src/silc/core/silc-core.c
943 lib/silcclient/silcapi.h
944 irssi/src/silc/core/silc-channels.c
945 lib/silcclient/client_keyagr.c
948 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Added silc_pkcs_public_key_compare to compare two
951 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
953 * Check that the client who set the founder mode on the
954 channel is the same client that is giving the founder
955 mode to itself. It is done by comparing the saved public
956 key (it is saved even in the authentication is passphrase).
957 Affected file silcd/command.c.
959 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Do not process packet for disconnected socket connection.
962 Affected file lib/silccore/silcpacket.c.
964 * Process the DISCONNECT packet through scheduler in the
965 client library. Affected file lib/silcclient/client.c.
967 * Fixed the silc_client_packet_parse to not to increase
968 the packet sequence number if the conn->sock and the
969 current socket connection is not same. This can happen
970 for example during key agreement when the conn includes
971 multiple socket connections (listeners). Affected file
972 lib/silcclient/client.c.
974 * The sender of the file transfer request now provides also
975 the pointer (listener) for the key exchange protocol. If
976 the listener cannot be created then it sends empty key
977 agreement and lets the receiver provide the listener.
979 Added `local_ip' and `local_port' arguments to the
980 silc_client_file_send. If they are provided they are used,
981 if not then it will attempt to find local IP address, if
982 not found or bind fails then the remote client will provide
985 Affected files are lib/silcclient/client_ftp.c and
986 lib/silcclient/silcapi.h.
988 * Extended the FILE SEND command to support defining the
989 local IP and port for key exchange listener. They are
990 optional. Affected file irssi/src/silc/core/silc-servers.c.
992 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Defined to WHOIS command reply the sending of fingerprint
995 of the client's public key (if the proof of posession of the
996 corresponding private key is verified by the server).
997 Updated to the protocol specification.
999 * Added support of receiving the client's public key's
1000 fingerprint in command reply in client library. Affected
1001 file is lib/silcclient/command_reply.c, and
1002 lib/silcclient/idlist.[ch].
1004 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Do not send over 128 chars long nickname to the server
1007 in NICK command. Affected file lib/silcclient/command.c.
1009 * Do not send over 256 chars long channel names to the server
1010 in JOIN command. Affected file lib/silcclient/command.c.
1012 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Assure that silc_server_close_connection cannot be called
1015 twice for same socket context. Affected file is
1018 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * Send error message to application if opening file for
1021 writing during file transfer fails. Affected file is
1022 lib/silcclient/client_ftp.c.
1024 Remove all file transfer sessions for a client that we're
1025 removing from ID cache.
1027 Affected file is lib/silcclient/client_ftp.c.
1029 * Fixed silc_net_addr2bin to return correct address. Affected
1030 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1032 * Fixed file transfer session removing on signoff notify.
1033 Affected file irssi/src/silc/core/silc-servers.c.
1035 * Added the SilcClientFileError to be returned in the monitor
1036 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1037 Affected file lib/silcclient/silcapi.h.
1039 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Fixed a crash in silc_client_ftp_free_sessions and
1042 silc_client_ftp_session_free_client. Affected file
1043 lib/silcclient/client_ftp.c.
1045 * Added `disabled' field in the SilcChannelEntry in the server
1046 to indicate if the server entry is disabled. Affected file
1047 silcd/idlist.h, silcd/command[_reply].c.
1049 * SILC server adds now /var/run/silcd.pid everytime it is
1050 started. Affected file silcd/silcd.c.
1052 * Added silc_server_packet_send_clients to send a packet to
1053 the provided table of client entries. Affected file
1054 silcd/packet_send.[ch].
1056 * Fixed a crash in client resolving in client_prvmsg.c in
1057 client library. Affected file lib/silcclient/client_prvmsg.c.
1059 * Do not actually remove the client directly from ID cache
1060 during SERVER_SIGNOFF, but invalidate it. This way we
1061 preserve the WHOWAS info for the client. Affected file
1062 silcd/server_util.c.
1064 * Fixed SERVER_SIGNOFF notify handling in the server. The
1065 server is now able to process incoming SERVER_SIGNOFF notify
1066 for a server that it doesn't even know about. It will remove
1067 the clients provided in the notify. Affected file
1068 silcd/packet_receive.c.
1070 * Check for partial packet in data queue after every packet that
1071 was found from the queue. Return and wait for more data if
1072 there is partial data in queue. Affected file is
1073 lib/silccore/silcpacket.c.
1075 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Added SilcClietFileError enum to indicate error in
1078 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1079 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1080 Affected files lib/silcclient/silcapi.h and
1081 lib/silcclient/client_ftp.c.
1083 * Check that newsize in silc_buffer_realloc is larger than
1084 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1086 * Added better monitor of file transfers. It now monitors
1087 key agreement protocol during the file transfer too. Added
1088 error reporting too. Affected files
1089 irssi/src/silc/core/silc-servers.c,
1090 irssi/src/fe-common/silc/module-formats.[ch].
1092 * Wrote a help file for FILE command.
1094 * Added silc_rng_global_get_byte_fast to get not-so-secure
1095 random data as fast as possible. Random data is read from
1096 /dev/urandom if available and from the SILC RNG if not
1097 available. It is used in padding generation. Affected file
1098 lib/silccrypt/silcrng.[ch].
1100 * All packets in client library are now processed synchronously.
1101 Optimized packet processing a lot. Affected file
1102 lib/silcclient/client.c.
1104 * All server connection packets are processing synchronously
1105 now in server, to optimize packet processing. Affected file
1108 * Include files are installed now only in Toolkit distribution
1109 if make install is given. Affected files: all Makefile.am's.
1111 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1113 * Assure that silc_client_notify_by_server_resolve does not
1114 resolve the client information multiple times. If it cannot

1116 file lib/silcclient/client_notify.c.
1118 * Fixed WHOWAS command reply calling. Affected file
1119 lib/silcclient/command_reply.c.
1121 * Removed all references to silc_idlist_get_client from the
1122 Irssi SILC client since that call is internal call used by
1123 the library. The Irssi SILC client will use now client
1124 retrieval functions found in silcapi.h.
1126 * Fixed a bug in resolving nickname info before sending
1127 private message. It used freed memory. Affected file
1128 irssi/src/silc/core/silc-servers.c.

1149 * Added silc_net_localip to return local host's IP address.
1150 Affected file lib/silcutil/silcnet.[ch].
1152 * If key exchange or rekey protocol is active for a connection
1153 parse all packets syncronously since there might be packets
1154 in packet queue that we are not able to process without first
1155 processing packets before them. Affected file silcd/server,
1156 lib/silcclient/client.c.
1158 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1159 whether library should continue processing the packet.
1160 Affected file lib/silccore/silcpacket.h.

1206 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1207 is incomplete and is being resolved, it won't be resolved
1210 Make sure also that USERS command reply does not resolve
1211 twice information. Affected file is
1212 lib/silcclient/command_reply.c.
1214 Make sure that silc_client_get_clients_by_list does not
1215 resolve twice same information.
1217 * Check for valid client->id in the silc_server_free_client_data.
1218 Affected file silcd/server.c.
1220 * Fixed /GETKEY nick@server not to crash if the server entry
1221 is not found. Affected file lib/silcclient/command.c.
1223 * Fixed the silc_server_check_cmode_rights to check the

1229 Affected file silcd/command.c.
1231 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1233 * Call the silc_server_udpate_servers_by_server in the
1234 primary router that comes back online in the backup resuming
1235 protocol. Otherwise it routes packets wrong. Affected file
1236 silcd/server_util.[ch], silcd/server_backup.c.
1238 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1241 lib/silcutil/silcbuffmt.[ch].
1243 * Redefined the SILC packet header to include the padding
1244 length. Affected file lib/silccore/silcpacket.[ch].
1246 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1247 length for maximum padding up to 128 bytes). Affected
1248 file lib/silccore/silcpacket.h.
1250 * Removed all backwards support for old 0.5.x MAC thingies.
1251 The SILC packet header change makes it impossible to be
1252 backwards compatible.
1254 * Send the ENDING packet with timeout in the backup resuming
1255 protocol. This is to assure that all routers has connected
1256 to the primary router. Affected file silcd/server_backup.c.
1258 * Changed the RNG to take the first IV from random data. It
1259 used to take it from zero actually. Changed the RNG also
1260 to use /dev/urandom during session. /dev/random is used
1261 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1263 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Changed the SILC packet header to have the first two bytes
1266 (the packet length) encrypted. Affected files aroung the
1267 code tree, lib/silccore/silcpacket.[ch]. Removed the
1268 SilcPacketCheckDecrypt callback. It is not needed anymore
1269 since the silc_packet_receive_process will determine now
1270 whether the packet is normal or special.
1272 * Implemented the unidirectional MAC keys. Affected files
1273 lib/silcske/silcske.c, silcd/protocol.c and
1274 lib/silcclient/protocol.c.
1276 * Implemented the packet sequence number to the MAC computation.
1277 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1278 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1279 lib/silcclient/protocol.c.
1281 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Allow backup router to announce servers. All servers
1284 announced by backup router are added to the global list
1285 automatically. Update hte server's socket to our primary
1286 router also when backup router announces a server.
1287 Affected file silcd/packet_receive.c.
1289 * Do not update the client->router in the function
1290 silc_server_udpate_clients_by_server if the client is on
1291 global list. We might fail to find any specific server
1292 for locally connected clients and local cell clients. They
1293 should still use the `from' and not `to' as client->router.
1294 This fixes backup router resuming protocol. Affected file
1295 silcd/server_util.c.
1297 * Decrease channel statistics count only if the channel
1298 deletion worked. Affected files are silcd/server.c and
1299 silcd/server_util.c.
1301 * Added silc_server_update_servers_by_server to update origin
1302 of all server entries. Used during backup router protocol.
1303 Affected files silcd/server_util.[ch], silcd/server.c. and
1304 silcd/backup_router.c.
1306 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1307 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1308 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1309 lib/silccrypt/silchmac.c.
1311 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Assure that router cannot reroute the same channel message
1314 to the sender. Affected file silcd/packet_receive.c.
1316 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1318 * Made better checks that the channel message is not sent
1319 to the router it came from. Affected file is
1320 silcd/packet_send.c. Fixed memory leak too.
1322 * Announce informations for incoming router connection, but
1323 only after checking if it is replaced by backup router.
1324 Affected file silcd/packet_receive.c.
1326 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Fixed the backup resuming protocol to work in multiple
1329 router environment. Affected file silcd/server_backup.c.
1331 * Route packet only to one router in the function
1332 silc_server_packet_send_to_channel. Affected file is
1333 silcd/packet_send.c.
1335 * Fixed silc_server_send_notify_dest to set the broadcast
1336 flag. Fixed the silc_server_send_notify_topic to actually
1337 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1338 Affected file silcd/packet_send.c.
1340 * Changed the SFTP Filesystem interface. Changed the
1341 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1342 the filesystem operation function. The SilcSFTPFilesystem
1343 is now a context that is allocated by all filesystem allocation
1344 functions and it already includes the operations structure
1345 and filesystem specific context. It is given as argument
1346 now to the silc_sftp_server_start. This made the interface
1347 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1348 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1350 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Changed the backup router adding and getting interfaces
1353 in the server. The router that will be replaced by the
1354 specified backup router is now sent as argument. Affected
1355 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1358 * Added silc_net_addr2bin_ne to return the binary form of
1359 the IP address in network byte order. Affected files
1360 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1362 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Check for existing server ID in silc_server_new_server
1365 and in silc_server_connect_to_router_final and remove the
1366 old entry if it exists. Affected file silcd/packet_receive.c,
1369 * Send the channel message always to only one router, either
1370 in upstream or downstream. Affected file is
1371 silcd/packet_send.c.
1373 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Wrote the definition of the backup resuming protocol to the
1376 protocol specification.
1378 * Removed one redundant channel key generation from normal
1379 server during joining procedure. Removed one redundant
1380 channel key sending from server to router during joining
1381 procedure. Affected file silcd/command.c.
1383 * Made minor bugfixes to the backup router resuming protocol.
1384 Affected file silcd/server_backup.c, server.c.

1393 resume the primary router position in the cell after the
1394 primary router comes back online. Affected files
1395 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1396 and silcd/server_util.[ch].
1398 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Sleep two (2) seconds after sending QUIT command to server.
1401 Affected file lib/silcclient/command.c.
1403 * Assure that if outgoing data buffer is pending do not force
1404 send any data. Affected file silcd/packet_send.c.
1406 * Assure that if outgoing data buffer is pending do not force
1407 send any data. Affected file lib/silcclient/client.c.
1409 * Implemented the backup router support when the primary router
1410 goes down. The servers and routers can now use the backup
1411 router as new primary router without loosing connectivity.
1413 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1415 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1416 in the server to indicate disabled entry. All data read
1417 from the connection will be ignored and no data is sent
1418 for entry that is disabled. Affected files are
1419 silcd/idlist.h, silcd/server.c.
1421 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1428 * Implemented memory filesystem (virtual filesystem) for
1429 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1432 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1434 * Implemented the SFTP (SSH File Transfer Protocol) to the
1435 lib/silcsftp. It includes SFTP client and SFTP server
1438 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1440 * Moved lib/silccore/silcprotocol.[ch] to the
1441 lib/silcutil library.
1443 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1444 take variable argument list pointer as argument. Affected
1445 file lib/silcutil/silcbuffmt.[ch].
1447 * Added silc_buffer_set function that is used to set data
1448 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1449 Affected file lib/silcutil/silcbuffer.h.
1451 * Changed various routines in the core library to use the new
1452 silc_buffer_set instead of allocating new buffer only for
1455 * Added 64-bit value formatting and unformatting support to the
1456 silc_buffer_[un]format routines. Affected file is
1457 lib/silcutil/silcbuffmt.[ch].
1459 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1460 to includes/bitmove.h.
1462 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Fixed channel user mode saving in client library. Affected
1465 file lib/silcclient/command[_reply].c.
1467 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1469 * Defined the file transfer to the SILC Protocol. Added
1470 new packet type SILC_PACKET_FTP and defined File Transfer
1471 Payload. The mandatory file transfer protocol is SFTP
1472 (SSH File Transfer Protocol). Affected file in addition
1473 of the internet draft is lib/silccore/silcpacket.h.
1475 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1476 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1477 is used as part of backup router protocol when the primary
1478 router of the cell is back online and wishes to resume
1479 the position as primary router.
1481 * Redefined the MAC generation keys in the protocol. The
1482 same key is not used anymore in both direction. Both
1483 direction will now use different keys for sending and
1484 receiving. This fixes a potential security flaw. This
1485 change causes incompatibilities in the protocol.
1487 * Redefined also the MAC computation from the packet.
1488 An packet sequence number is now added to the MAC
1489 computation. This prevents possible replay attacks against
1490 the protocol. This change too causes incompatibilities
1493 Added `sequence' field to the SilcPacketContext to hold
1494 the current sequence number for the packet.
1496 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1498 * Added `created' field to the SilcIDListData in the file
1499 silcd/idlist.h to indicate the time when the entry was
1502 * Added `created' field to the SilcChannelEntry too. Affected
1503 file silcd/idlist.h.
1505 * Added `creation_time' aguments to all the announcement functions
1506 in the server. If it is provided then only the entries that
1507 was created after the provided time frame are actually
1508 announced. Affected file silcd/server.[ch].
1510 * The protocol says that the Channel ID's IP address must be
1511 based on the router's IP address. Added check for this in
1512 the silc_server_new_channel when processing incoming New Channel
1513 Payload. Affected file silcd/packet_receive.c.
1515 * Print out the correct version with --version in SILC client.
1516 Affected file irssi/src/silc/core/silc-core.c.
1518 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Fixed WHOWAS command to check for completnes of the client
1521 entry always, not just when the command is coming from client.
1522 Affected file silcd/command.c.
1524 * Added new function silc_server_packet_queue_purge to purge the
1525 outgoing data queue to the network. After the function returns
1526 it is guaranteed that the outgoing packet queue is empty.
1527 Affected file silcd/packet_send.[ch].
1529 * Purge the outgoing packet queue in the rekey protocol's final
1530 callback to assure that all rekey packets go to the network
1531 before quitting the protocol. Affected file silcd/server.c.
1533 * Added silc_client_packet_queue_parse as similar function as
1534 in server to the client library. The affected file is
1535 lib/silcclient/client.c.
1537 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1539 * Splitted silcd/server.c and created silcd/server_util.[ch]
1540 for utility functions.
1542 * Added new socket flag SILC_SF_DISABLED to indicate that the
1543 connection is open but nothing can be sent to or received from
1544 the connection. Affected file lib/silcutil/silsockconn.[ch].
1545 The checking for disabled socket is checked in the low level
1546 silc_socket_write and silc_socket_read functions.
1548 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * Allow only nicknames and channel names that fits into the
1551 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1553 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * When processing JOIN command reply in server check that if
1556 the channel exists in our global list we'll move it the local
1557 list. Affected file silcd/command_reply.c.
1559 * Fixed the check whether client is joined on the channel already
1560 in JOIN command. Affected file lib/silcclient/command.c.
1562 * Fixed the JOIN command reply to check whether the channel
1563 already exists. Affected file lib/silcclient/command_reply.c.
1565 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Added silc_ske_status_string to map the SKE error numbers
1568 to readable strings. The affected files are
1569 lib/silcske/silcske[_status].[ch].
1571 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Do not show the private channels on the WHOIS channel list
1574 as it is not allowed by the protocol. The affected file is
1577 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Assure that the packet length digged from the actual packet
1580 is something sensible in the silc_packet_decrypt_rest_special
1581 in lib/silccrypt/silcpacket.c.
1583 * Free and NULL the allocated pointer in silc_hmac_alloc if
1584 the HMAC allocation fails. The affected file is
1585 lib/silccrypt/silchmac.c.
1587 * Print the selected security properties to the log files in
1588 the server. Affected file silcd/protocol.c.
1590 * Add SKE's reference counter even if calling the completion
1591 callback manually. Otherwise it goes negative, although it
1592 does not cause any problems. The affected file is
1593 lib/silcske/silcske.c.
1595 * Remove the client entry with short timeout after giving the
1596 KILL command. Affected file lib/silcclient/command.c.
1598 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1599 case all found clients are already disconnected (WHOWAS would
1600 found them) in the server. Affected file silcd/command.c.
1602 * Update the last_receive (time of last data received) to be
1603 updated only when received private or channel message so that
1604 the idle time showed in WHOIS makes more sense.
1606 * Added boolean field `valid' in to the SilcClientEntry in the
1607 client library to indicate whether the entry is valid or not.
1608 This fixes the nickname change bug on channel when changing
1609 the nickname to be same than the old (like nick to Nick) the
1610 nickname formatter doesn't set the new nick anymore to Nick@host.
1611 Affected file lib/silcclient/idlist.[ch].
1613 * Now actually fixed the nickname changing on disconnection.
1614 Added new function silc_change_nick to the Irssi SILC Client.
1615 Affected file irssi/src/silc/core/client_ops.c,
1616 irssi/src/silc/core/silc-nicklist.[ch].
1618 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * Check that the public key exists in the GETKEY command before
1621 trying to encode it. Affected file silcd/command.c.
1623 * Print some notifications on received public keys with GETKEY
1624 command in the Irssi SILC Client. Affected files are
1625 irssi/src/fe-common/silc/module-formats.[ch],
1626 irssi/src/silc/core/client_ops.c.
1628 * Use IDENTIFY command to resolve the server information in the
1629 GETKEY command instead of INFO command. Affected file
1630 lib/silcclient/command.c.
1632 * All command reply functions in the client library now calls
1633 the pending command reply callbacks even if an error has
1634 occurred. The server has done this a long time and now it was
1635 time to move the client library to this as well. Now all
1636 errors can be delivered back to the pending command reply
1637 callbacks if necessary. Affected files are
1638 lib/silcclient/command[_reply].[ch].
1640 * Change the nickname on disconnection back to the username
1641 because in reconnect the server will enforce it to it anyway.
1642 Affected file irssi/src/silc/core/silc-servers.c.
1644 * Fixed a config file parsing bug in the Irssi SILC client.
1645 Affected file irssi/src/silc/core/clientconfig.c.
1647 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * When printing the channel mode on JOIN, verify that the
1650 channel key and channel's HMAC are valid. Affected file
1651 irssi/src/silc/core/client_ops.c.
1653 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1656 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1657 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1659 * Removed channel key rekey task deleting from the function
1660 silc_server_save_channel_key. Affected file silcd/server.c.
1661 Added explicit timeout task context instead that is used to
1662 delete the task if we are registering a new task before the
1663 new task has elapsed.
1665 * When channel key rekey occurs the client library now saves
1666 the old channel key for a short period of time (10 seconds) and
1667 is able to use it in case some is still sending channel
1668 messages encrypted with the old key after the rekey. Affected
1669 file lib/silcclient/[idlist.h|client_channel.c].
1671 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * Added check to the silc_server_new_id_real to not accept
1674 new ID if it is the sender's own ID. Affected file is
1675 silcd/packet_receive.c.
1677 * Assure that we do not announce ourself or the one we've
1678 sending our announcements when we're router and are announcing
1679 servers to our primary router. Affected file silcd/server.c.
1681 * Fixed silc_server_command_identify_check_client to assemble
1682 correct WHOIS packet. It send corrupted WHOIS packet and
1683 caused problem with router to router connections. Affected
1684 file silcd/command.c.
1686 Fixed also silc_server_command_whois_check the same way
1687 as for the IDENTIFY command.
1689 * Added new SilcIDListStatus to the server in the SilcIDListData
1690 structure. The status now includes the current status of
1691 the entry (like registered, resolved etc.). Affected file
1692 silcd/idlist.[ch]. Defined a bunch of different status types
1693 as well. This replaced the old boolean registered field as well.
1695 Added resolve_cmd_ident field to the SilcClientEntry structure
1696 too so that if the entry is for example being resolved so
1697 another command may attach to the same pending command reply
1698 without requiring to resolve the same entry again. This concept
1699 should optimize the WHOIS and the IDENTIFY resolving under
1700 heavy load by taking away unnecessary resolving for entries
1701 that are being resolved already.
1703 Added support for adding multiple pending commands for one
1704 command idenfier. Affected file silcd/command[_reply].[ch].
1706 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1707 before deleting the data. Otherwise the hash table will have
1708 freed data in comparison functions. Affected file is
1709 silcd/command_reply.c.
1711 * Fixed silc_idlist_replace_client_id to add the new entry to
1712 the cache with NULL nickname. Otherwise there will be invalid
1713 memory as the nickname after the nickname is freed. Affected
1714 file silcd/packet_receive.c.
1716 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1717 saved into wrong slots because the previous number of entries
1718 was not taken into account. Affected file silcd/idlist.c.
1719 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1721 * If we are router and we receive JOIN notify to a channel that
1722 does not have any users then notified client is marked as the
1723 channel founder, as it is it. The affected file is
1724 silcd/packet_receive.c
1726 * Added to the extended hash table API's table_del_*ext functions
1727 the destructor as argument too, so that the caller can decide
1728 which destructor to use or whether to use destructor at all.
1729 Affected file lib/silcutil/silchashtable.[ch].
1731 * Fixed ID Cache purging. It actually deleted the entries from
1732 the hash table after the data was freed. The hash table ended
1733 up comparing freed memory. The affected file is
1734 lib/silccore/silcidcache.c.
1736 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Fixed Irssi SILC client's KILL command's HELP syntax.
1740 * The USERS command now resolves the detailed user information
1741 if the userinfo field is missing. Affected file is
1742 lib/silcclient/command_reply.c.
1744 * Do not print error in silc_file_read if the read file does
1745 not exist. Just silently return NULL. Affected file is
1746 lib/silcutil/silcutil.c.
1748 * Fixed the silc_log_output to not wine about NULL filename
1749 and to not create some bogus " " filename. Affected file is
1750 lib/silcutil/silclog.c.
1752 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1754 * Fixed various printing bugs on the user interface in the
1755 Irssi SILC Client. Minor changes that were forgotten from
1758 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1760 * Fixed the configure.in.pre and the compilation and distribution
1761 environment to support the new autoconf 2.52. That version is
1762 now required to compile the CVS trunk.
1764 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1767 to generally parse user@fqdn format strings. Affected file
1768 lib/silcutil/silcutil.c.
1770 * Added nickname_format and nickname_force_format fields to the
1771 SilcClientParams structure. The first one defines the format
1772 for the nicknames that the library will enforce if the receives
1773 multiple same nicknames. The second one is boolean value and
1774 can be used to force the library to always enforce the format
1775 to the nicknames regardles whether there are multiple nicknames
1776 or not. This configurable formatting was employed to flexibly
1777 support accessing multiple nicknames from the user interface.
1778 The userinterface can now set the nicknames to what ever format
1779 they prefer. Affected file lib/silcclient/silcapi.h.
1781 Added function silc_client_nickname_format to the file
1782 lib/silcclient/idlist.c. It performs the nickname formatting.
1784 Added new field `hostname´ to the SilcClientEntry context.
1785 It holds the hostname of the client. Affected file is
1786 lib/silcclient/idlist.h.
1788 * Irssi SILC Client sets the nicknames in nick@hostn format.
1789 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1790 irssi/src/silc/core/silc-core.c.
1792 The WHOIS printing now also shows both the real nickname and
1793 the formatted nickname so that user knows how to access the
1794 user if there are multiple same nicknames cached. Affected
1795 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1796 printing formatting too to take the hostname now as a separate
1797 argument. The Affected file is
1798 irssi/src/fe-common/silc/modules-formats.[ch].
1800 * Changed the silc_client_get_clients_local to accept the formatted
1801 nickname as argument. It accepts the real nickname too but the
1802 formatted nickname can be used to find the true entry from
1803 multiple entries. Affected file lib/silcclient/silcapi.h and
1804 lib/silcclient/idlist.c.
1806 * Added nickname_format_parse field to the SilcClientParams.
1807 It is a callback function provided by the application to parse
1808 the nickname out of the formatted nickname string. The library
1809 calls it to get the nickname from the formatted string. Since
1810 the application generally knows better the format of the nickname
1811 string it parses it instead of the library, even though library
1812 encodes the formatted string. If the callback function is not
1813 provided then the library will use the string as is. The
1814 affected file is lib/silcclient/silcapi.h.
1816 * All the nickname strings passed to the client library in
1817 commands are now expected to be formatted nickname strings.
1818 If the command does not support the formatted nickname string
1819 it will assume that the sent string is the actual nickname.
1820 Affected file lib/silcclient/command.c.
1822 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Added public key authentication support to OPER and SILCOPER
1825 commands in the client library. Affected file is
1826 lib/silcclient/command.c.
1828 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * Changed the get_auth_methdod client operation to be asynchronous.
1831 It can be async if the application resolves the authentication
1832 method from the server during the negotiation. Added new
1833 SilcGetAuthMeth completion callback that the application will
1834 call after resolving the authentication method.
1836 Added function silc_client_request_authentication_method that
1837 the application can use to resolve the authentication method
1838 from the server. Added also SilcConnectionAuthRequest callback
1839 that the library will call after the server has replied. The
1840 application can call this function if it does not know the
1841 current authentication method.
1843 Affected files are lib/silcclient/client.c and
1844 lib/silcclient/silcapi.h.
1846 * The Irssi SILC client now automatically resolves the authentication
1847 method incase any configuration information is not present (and
1848 currently there never is). The affected file is
1849 irssi/src/silc/core/client_ops.c.
1851 * Fixed public key authentication from the client library.
1852 Affected file lib/silcclient/protocol.c. Changed also the
1853 protocol specification about the public key authentication in
1854 the connection authentication protocol. The actual data to be
1855 signed is now computed with a hash function before signing.
1857 * Fixed the public key authentication from the server as well.
1858 Affected file silcd/protocol.c.
1860 * Removed the mlock()'s from the memory allocation routines.
1861 Affected file lib/silcutil/silcmemory.c. The ./configure does
1862 not check anymore for the mlock(). Affected file is
1865 * Fixed USERS command in server to allow the execution of the
1866 command for private and secret channels if the client sending
1867 the command is on the channel. Affected file silcd/command.c.
1869 * Fixed silc_client_get_clients_local to return the clients
1870 count correctly. It could return wrong value. Affected file
1871 lib/silcclient/idlist.c.
1873 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1876 types. The assembler optimizations seemed not to like 64-bit
1877 data types. The assmebler optimizations thus are now enabled
1878 also for BSD systems as opposed to only enable them for Linux.
1880 * Do not check for threads at all on BSD systems. Affected
1881 file configure.in.pre.
1883 * Removed -n and -h options from the Irssi SILC Client since
1884 they are not used in silc.
1886 * Fixed the prime generation to assure that the first digit
1887 of the generated random number is not zero since our conversion
1888 routines does not like number strings that starts with zero
1889 digit. If zero digit is seen the random number is regenerated.
1890 This caused some corrupted RSA keys when the zero first digit
1891 was met. Affected file lib/silcmath/silcprimegen.c.
1893 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1895 * Fixed WIN32 configuration in the ./configure script.
1896 Fixed to include xti.h on environments that has it.
1897 Patches by Carsten Ilchmann and andrew.
1899 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1901 * Changed the silc_id_create_client_id to be collision
1902 resistant. It is now assured that there cannot be created
1903 two same client ID's. I suspect that some weird bugs in
1904 the server were actually caused by duplicate Client IDs.
1905 Affected file silcd/serverid.[ch]. A router receiving
1906 new ID now also assures and informs the sending server
1907 if the ID caused collision.
1909 * Changed the silc_id_create_channel_id to also assure that
1910 there are no collisions.
1912 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Statement about ignoring the Mutual Authentication flag when
1915 performing rekey with PFS was a bit misleading. It is ignored
1916 if it was set in the initial negotiation, it cannot be even
1917 set in the rekey. Fixed in the ke-auth draft. Started the
1918 new versions of the protocol drafts in the doc/.
1920 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * Fixed a bug in silc_client_command_identify_save when saving
1923 new channel information. The channel name was no duplicated
1924 and caused crash on exit. Affected file is
1925 lib/silcclient/command_reply.c.
1927 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Fixed the getkey command handling in the server. Send just
1930 empty OK reply to the sender if the key could not be fetched
1931 (but everything else was ok, like the key just was not available).
1932 Changed the public key parameter to optional in the protocol
1933 specs so that empty OK reply can be sent. Affected file
1936 Added a message to Irssi SILC client to tell to user if the
1937 server did not return a public key.
1939 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1941 * Fixed a channel key regeneration bug. It registered new
1942 timeout tasks exponentially until all system resources were
1943 used. Affected file silcd/server.c.
1945 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Added the SILC Document generator to the scripts/silcdoc.
1948 It can be used to generate the Toolkit Reference Manual out
1949 of the source tree. Internally it will also use the RoboDoc
1950 generator now imported in util/robodoc.
1952 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Added couple of return's in rekey protocol if error orccurred
1955 during the protocol. The execution must be terminated.
1956 Affected file silcd/protocol.c. Also, terminate the protocol
1957 always with timeout.
1959 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * The client's Client ID was created initally from the wrong
1962 nickname (it could have been in format nick@host) in the
1963 silc_server_new_client. Affected file silcd/packet_receive.c
1965 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Added some SILC_LOG_ERROR's to various error conditions
1968 if client could not be added to ID cache. Affected files
1969 silcd/packet_receive.c and silcd/server.c.
1971 * When client's sock->user_data is freed, NULL also the
1972 client->router and client->connection pointers. Added check
1973 for these pointers being NULL to various places around the
1974 code. Affected file silcd/server.c.
1976 * Added client->data.registered == TRUE checks to various
1977 places around the code to assure that unregistered client's
1978 are not handled when it is not allowed. Affected file
1981 * Added `bool registered' fields to all
1982 silc_idlist_[server|client]_get_* routines to indicate whether
1983 the fetched client needs to be registered or not. Affected
1984 file silcd/idlist.[ch].
1986 * Add your own entry as registered to the ID cache in the
1987 server. Affected file server.c.
1989 * Fixed a bug in silc_server_new_server. The SilcServer was
1990 set as the new server's context instead of SilcServerEntry.
1991 This naturally caused some weird bugs.
1993 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Do not delete the channel rekey task when adding it
1996 for in silc_server_create_channel_key.
1998 * Changed the silc_server_create_channel_key to return
1999 TRUE or FALSE to indicate the success of the channel key
2002 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Fixed MSVC++ project files and added missing files to
2005 Makefiles under win32/.
2007 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Do not add TCP_NODELAY flag if the operating system
2010 does not have it defined. Affected files are
2011 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2013 * Fixed buffer overflow from Irssi SILC Client. Affected
2014 file irssi/src/fe-common/core/themes.c.
2016 * Fixed double free in client library in the file
2017 lib/silcclient/client.c when disconnecting from server.
2019 * Applied double free patch from cras to Irssi SILC client.
2020 Affected files irssi/src/core/[modules/expandos].c
2022 * Fixed the disconnection handling to Irssi SILC Client.
2023 The application must call silc_client_close_connection
2024 in ops->connect client operation in case of failure of
2025 the connection. Affected file is
2026 irssi/src/silc/core/client_ops.c.
2028 * Do not set sock->protocol to NULL in the function
2029 silc_client_close_connection after executing the protocol's
2030 final callback since the sock might not be valid anymore.
2031 Affected file lib/silcclient/client.c.
2033 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2035 * Do not enable SILC_THREADS if the linking with libpthread
2036 did not happen. Affected file configure.in.pre.
2038 * Added notion to protocol specification that server must
2039 verify the sent authentication payload with CMODE when
2040 setting the channel founder key. Implemented it to the
2041 server. Affected file silcd/command.c.
2043 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Added _EXTRA_DIST SILC distribution variable to the
2046 distributions file. It is used to conditionally add extra
2047 files or directories to the specific distribution. Affected
2048 files ./prepare, Makefile.am.pre and distributions.
2050 Removed the `_' from the start of the distribution names.
2053 * Added README.WIN32 for instructions to compile the Toolkit
2056 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2058 * Fixed a double free in disconnection in the server. Affected
2059 file is silcd/server.c.
2061 * Fixed the lib/silcske/groups.c to work now also with GMP
2062 MP library. The string conversion did not work when using
2063 specific base and the base is indicated in the string as well.
2065 * Created win32/ directory which now includes MSVC++ specific
2066 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2067 It will appear only in the toolkit distribution
2069 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * Changed the key material distribution function in case when
2072 the hash output is too short. The data is now concatenated
2073 a bit differently than it used to. Made the change to the
2074 SKE protocol specification.
2076 * Added better GMP detection to configure.in.pre. A patch
2079 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Fixed a minor bug in SKE that might cause some problem on
2082 some platforms. Affected file lib/silcske/silcske.c.
2084 * Added the cookie checking for initiator in the SKE. It checks
2085 that the responder returns the sent cookie unmodified. The
2086 affected file is lib/silcske/silcske.c. Added new SKE
2087 error type INVALID_COOKIE that can be sent during the
2088 negotiation. Fixed some memory leaks as well.
2090 * Added the "invalid cookie" error message to Irssi SILC client's
2093 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Added `task_max' field to the SilcClientParams to indicate
2096 the maximum tasks the scheduler can handle. If set to zero,
2097 default values are used. Affected file lib/silcclient/silcapi.h.
2099 * Fixed memory leaks in silc_client_close_connection. Affected
2100 file lib/silcclient/client.c.
2102 * Added silc_client_del_client_entry to client library to free
2103 all memory of given client entry. Affected file is
2104 lib/silcclient/idlist.[ch].
2106 * Added new functions silc_client_del_channel and
2107 silc_client_del_server to delete channel and server entries.
2108 Affected file lib/silcclient/[silcapi.h/idlist.c].
2110 * Removed silc_client_del_client_by_id from silcapi.h.
2112 * Fixed the INFO command to return the server's own info
2113 correctly when querying by Server ID. Affected file is
2116 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2118 * Removed the non-blocking settings in WIN32 code in the
2119 silc_sock_[read/write] and added SleepEx instead. Affected
2120 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2121 of input data is now checked with FIONREAD and ioctlsocket.
2123 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Call silc_schedule_task_del_by_context in the
2126 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2127 Affected file lib/silccore/silcprotocol.c.
2129 * Call silc_protocol_cancel for active protocols in the
2130 silc_server_close_connection if the funtion
2131 silc_server_free_sock_user_data has not been called.
2132 Affected file silcd/server.c.
2134 * Generic tasks cannot be deleted using the del_by_fd
2135 task deleting function since generic tasks does not match
2136 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2138 * Added a notion to SILCOPER help file that the SILCOPER works
2139 only on router server, not on normal server.
2141 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2143 * Added for WIN32 support for the new scheduler as well.
2144 Affected file lib/silcutil/win32/silcwin32schedule.c.
2146 * Fixed the SHA1 implementation to work on various platforms.
2148 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2151 API. It is part of the scheduler now. Everything else is
2152 as previously but some functions has changed their names.
2153 Checkout the lib/silcutil/silcschedule.h for the interface.
2154 Updated all applications to use the new interface. Affected
2155 files are lib/silcutil/silcschedule.[ch].
2157 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2159 * Found a bug in the SKE implementation. The HASH value,
2160 specified by the protocol, was not computed correctly. The
2161 public key of the responder was not added to the computation
2162 even though it is mandatory. Affected file lib/silcske/silcske.c.
2163 This unfortunately causes incompatibilities with older
2164 clients and servers.
2166 * Added WIN32 specific network init and uninit functions:
2167 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2168 the Winsock2. Affected file lib/silcutil/silcnet.h and
2169 lib/silcutil/win32/silcwin32net.c.
2171 * Set the socket always to nonblocking mode on WIN32 after
2172 reading data or writing data. Affected file is
2173 lib/silcutil/win32/silcwin32sockconn.c.
2175 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * Fixed various compilation problems under WIN32. Affected
2178 files lib/silcutil/win32/silcwin32thread.c and
2179 lib/silcutil/win32/silcwin32schedule.c.
2181 * Removed all _internal.h #includes from public header
2182 files. Internal headers must never be included from
2185 Removed also the lib/silcske/payload_internal.h file.
2187 * All include files that may be needed (public and some others
2188 included by the public headers) by application developers are
2189 now copied to the ./includes directory. It does not copy any
2190 internal headers. Affected file Makefile.defines.pre and all
2191 Makefile.am's under lib/ and subdirs.
2193 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Do not change the ~/.silc directory's permissions automatically.
2196 Affected file irssi/src/silc/core/clientutil.c.
2198 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Do not cancel the protocol in silc_server_close_connection
2201 it might cause recursion. Now cancelled in the function
2202 silc_server_free_sock_user_data. Affected file silcd/server.c.
2204 * Fixed the silc_server_remove_clients_by_server to regenerate
2205 the channel keys correctly finally. Added also new function
2206 silc_server_remove_clients_channels to actually do it.
2207 Affected file silcd/server.c.
2209 * Fixed the silc_server_new_channel to not crash by giving
2210 wrong router to the new channel. Affected file is
2211 silcd/packet_receive.c.
2213 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2216 which is given as argument to the silc_client_alloc now.
2217 It can be used to configure the client and set various parameters
2218 that affect the function of the client.
2220 * The USERS command in server did not check whether the channel
2221 is private or secret. Affected file silcd/command.c.
2223 * Added new argument to the USERS command in protocol specification.
2224 The USERS command now can take the channel name as argument
2225 as well. Added support for this in client and server and
2226 updated the protocol specs.
2228 * Completed the GETKEY command in client. It can be now used
2229 to fetch also servers public key not only some clients.
2230 Affected files lib/silcclient/command[_reply].c.
2232 * Added silc_client_get_server to return server entry by the
2233 server name. Affected files lib/silcclient/silcapi.h and
2236 * Redefined the IDENTIFY command in protocol specification to be
2237 more generic. It now can be used to query information about
2238 any entity in the SILC Network, including clients, servers and
2239 channels. The query may be based either the entity's name
2240 or the ID. Added support for this in both client and server.
2242 Affected files silcd/command.c and lib/silcclient/command.c
2243 and command_reply.c.
2245 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2246 the _from_client and _from_server functions. Affected file
2249 * Added silc_client_get_channel_by_id_resolve to the file
2250 lib/silcclient/silcapi.h to resolve channel information by
2251 its ID. Added also silc_client_get_channel_by_id that
2252 does not resolve it from the server.
2254 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Added SilcServerEntry context into the client library
2257 to represent one server. The INFO command now allocates
2258 these to save the resolved server info. For now on the
2259 client library will also keep information about servers,
2260 connected and resolved with INFO.
2262 The INFO command now allocates the SilcServerEntry context
2263 and saves the server info there. The COMMAND_REPLY in
2264 the INFO now returns the parameters to application in
2265 same order as defined in the protocol specification.
2267 The entries are cached in the client->server_cache.
2269 * The INFO command is now issued after received the Client ID
2270 from the server. Affected file lib/silcclient/client.c.
2272 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2273 to the application as the mode changer might be server.
2274 It is guaranteed that NULL is not returned anymore to the
2275 application. Affected file lib/silcclient/client_notify.c.
2277 The ID Type is now also passed to the application so that
2278 it can check whether the returned entry is SilcClientEntry
2281 Added new function silc_client_get_server_by_id to return
2282 the server entry by ID. Affected files are the
2283 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2285 * Do not create the channel in the Irssi SILC Client when issuing
2286 the JOIN command but when received the sucessful JOIN command
2287 reply. Otherwise the channel might get created even though we
2288 could not join it. The Affected file is
2289 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2291 * Fixed a channel joining bug in router. The router must also
2292 check the channel modes, invite and ban lists etc. when serving
2293 the JOIN command sent by normal server. Affected file is
2294 silcd/command.c. The router now resolves the client's
2295 information from the server who sent the JOIN command if it
2296 does not know it, and processes the JOIN command only after
2299 * Changed the SilcCommandCb to take new argument; void *context2.
2300 Affected file lib/silccore/silccommand.h
2302 The second argument in the command callbacks in the server now
2303 includes the SilcServerCommandReplyContext if the command was
2304 called as pending command callback from the command reply.
2305 Otherwise it is NULL. When called as pending the status of the
2306 command reply will be checked and if it was erronous the
2307 error will be sent to the original sender of the command.
2308 This way the client always receives the error messages even
2309 though the server was actually the one who received the error
2310 when it resent the command to router, for example. Affected
2311 files silcd/command[_reply].[ch].
2313 * Fixed sending WHOWAS command's error message to client if
2314 the requested client could not be found. It was missing.
2317 * Changed the CMODE and CUMODE commands reply arguments in the
2318 protocol specification. The Channel ID is now sent in both
2319 of the commands to identify the channel. Implemented this
2320 new feature to the client and server. Affected files
2321 lib/silcclient/command_reply.c and silcd/command.c.
2323 * Made better checks for invite and ban lists in the JOIN
2324 command in server. Affected file silcd/command.c.
2326 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * The server now performs the incoming host IP/DNS lookup
2329 using the silc_socket_host_lookup and thus does not block
2330 the server anymore. Affected file silcd/server.c.
2332 * Completed the multi-thread support for SILC Scheduler in
2333 the lib/silcutil/silcschedule.c.
2335 * Fixed the configure.in.pre to detect the pthread correctly
2338 * Fixed a deadlock in silc_task_queue_wakeup in the file
2339 lib/silcutil/silctask.c.
2341 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Added new function silc_schedule_wakeup that is used in
2344 multi-threaded environment to wakeup the main thread's
2345 schduler. It needs to be used when a thread adds a new task
2346 or removes a task from task queues. After waking up, the
2347 scheduler will detect the task queue changes. If threads
2348 support is not compiled in this function has no effect.
2349 Implemented the wakeup mechanism to both Unix and WIN32
2350 systems. Affected files are lib/silcutil/silcschedule.[ch],
2351 lib/silcutil/unix/silcunixschedule.c and the
2352 lib/silcutil/win32/silcwin32schedule.c.
2354 * Added new function silc_task_queue_wakeup to wakeup the
2355 scheduler by the specified task queue. Affected file
2356 lib/silcutil/silctask.[ch].
2358 * The silc_socket_host_lookup_start now wakes up the scheduler
2359 after adding the timeout task. Affected file is
2360 lib/silcutil/silcsockconn.c.
2362 * The silc_socket_host_lookup is synchronous now if the threads
2363 support is not compiled in. However, the callback is still
2364 called asyncronously through the scheduler, anyway. Affected
2365 file lib/silcutil/silcsockconn.c.
2367 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Added new function silc_socket_host_lookup to perform
2370 asynchronous IP and FQDN lookups for the socket connection.
2371 Affected files lib/silcutil/silcsockconn.[ch].
2373 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2376 that may or may not compile the mutex support in.
2378 Changed the silc_mutex_alloc interface. It allocates the
2379 mutex now to the sent pointer and returns TRUE or FALSE.
2381 Affected file lib/silcutil/silcmutex.h.
2383 * Wrote the SILC Task Queue interface to support multi-threads.
2384 Affected file lib/silcutil/silctask.[ch].
2386 * Wrote the SILC Scheduler to support multi-threads. Affected
2387 file lib/silcutil/silcschedule.c.
2389 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2392 in lib/silcutil/win32/.
2394 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Defined SILC Mutex API and SILC Thread API and implemented
2397 them for Unix. Affected files are
2398 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2399 lib/silcutil/unix/silcunixmutex.c and
2400 lib/silcutil/unix/silcunixthread.c.
2402 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2404 * Fixed the silc_server_remove_clients_by_server's channel
2405 key re-generation. The hash table handling was incorrect
2406 and would not work with many channels. Affected file is
2409 * Fixed some memory leaks around the server code.
2411 * Rewrote the silc_server_get_users_on_channel to support IPv6
2412 based Client ID's. Affected file silcd/server.c.
2414 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2415 specification. However, a separate document must be written
2416 to define the detailed signing procedure and the payload
2417 associated with the flag. Defined the flag to the
2418 lib/silccore/silcchannel.h as well.
2420 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Changed the dynamic tables to static size tables in the
2423 lib/silccrypt/silchmac.c.
2425 * Removed GCC dependencies from the code. A patch by cras.
2427 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Do not show the error "Error receiving packet bla bla"
2430 in server if it really was not an error (-2 means that reading
2431 is pending). Affected file silcd/server.c.
2433 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Fixed a possible crash in silc_server_remove_clients_by_server
2436 in silcd/server.c. Fixed there also some memory leaks.
2438 * Fixed the silc_idlist_replace_client_id. It could replace
2439 wrong key in the hash table. Affected file silcd/idlist.c.
2441 * Do not check whether there are global users on the channel
2442 if the channel->global_users is FALSE. Affected functions
2443 silc_server_remove_from_one_channel and
2444 silc_server_remove_from_channels in silcd/server.c. Also,
2445 do not check if the removed client is local as we can be
2446 sure that global client was not removed from the channel
2447 and checking for global users is not needed.
2449 * The silc_server_remove_clients_by_server now re-generates
2450 the channel keys correctly for those channels that had
2451 clients removed from them. Affected file silcd/server.c.
2453 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Found the reason of random crashes in the server. We weren't
2456 ignoring the SIGPIPE signal (which can be sent in write())
2457 and it crashed the server. Affected file silcd/silcd.c.
2459 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Assure that sock->user_data is not NULL in the function
2462 silc_server_packet_send in silcd/packet_send.c.
2464 * Disconnect the remote connection if it could not be added
2465 to any ID lists in the server. The affected file is
2468 * Check in silc_server_packet_send[_real/dest] that the
2469 socket is not disconnecting and ignore the data if it is.
2470 Affected file silcd/packet_send.c.
2472 * Define inline to __inline on native WIN32 compilation.
2473 Affected file includes/silcwin32.h.
2475 * Added some explicit type casts for inline code since MSVC
2476 require them. Affected files lib/silcutil/silcbuffer.h,
2477 lib/trq/silcdlist.h and lib/trq/silclist.h.
2479 * Print warning in log files from now on if the packet
2480 decryption fails. Affected file silcd/server.c.
2482 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2484 * Changed the `say' client operation's interface to accept
2485 new `type' argument to indicate the type of the message sent
2486 by the library. The application may filter the library's
2487 messages according the type. The affected file is the
2488 lib/silcclient/silcapi.h.
2490 * Added two new functions to lib/silcclient/silcapi.h:
2491 silc_client_del_client and silc_client_del_client_by_id.
2492 Affected file lib/silcclient/idlist.c.
2494 * Moved the clientincludes.h from includes/ to silc/ and
2495 serverincludes.h from includes/ to silcd/.
2497 * The modes for the CMODE and CUMODE are now passed as
2498 uint32 for application with COMMAND_REPLY. The affected
2499 file is lib/silcclient/command_reply.c.
2501 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * /WHOIS without arguments shows client's own information.
2504 Affected file lib/silcclient/command.c.
2506 * Changed PING to not accept any arguments. The specs
2507 says that client can ping only the connected server so
2508 requiring an argument is not needed. Affected file is
2509 lib/silcclient/command.c.
2511 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2513 * Fixed a fatal bug in private message sending and reception
2514 encryption and decryption when using private message keys.
2515 The implementation was incorrect and did not follow the
2516 specification. It causd that some of the message were
2517 lost since it did not use the sending and receiving keys
2518 as the protocol suggests. This has been fixed and will cause
2519 incompatibilities with older clients when sending private
2520 message encrypted with private message keys. Affected files
2521 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2522 and various other in Irssi SILC Client.
2524 Added `responder' boolean argument to the functions
2525 silc_client_add_private_message_key[_ske] to indicate when
2526 the key is added as responder or initiator of the key
2529 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Removed the silc_ske_check_version function and created
2532 a SilcSKECheckVersion callback. Added also a function
2533 silc_ske_set_callbacks that is now used to set all SKE
2534 callbacks. The callback functions are not given to
2535 the SKE functions anymore, but this function is used to
2538 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2540 * Added `silc_version' argument to the silc_client_alloc
2541 to define the version of the application for the library.
2542 The library will use the version string to compare it
2543 against the remote host's (usually a server) version
2544 string. Affected file lib/silcclient/silcapi.h
2546 * Added the KE protocol context to Key Agreement context
2547 in client library so that we can abort the SKE if it
2548 is in process when we get timeout. Affected file is
2549 lib/silcclient/client_keyagr.c.
2551 * Do not resolve the client ID forever if it returns in the
2552 first time that such client does not exist. This was done
2553 for example with private message. Affected file is
2554 lib/silcclient/client_prvmsg.c.
2556 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2558 * Do not add regex.h for WIN32. The affected file
2559 includes/silcincludes.h.
2561 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2562 not work yet 100%. It generates the DLL's automatically
2563 when compiling with --with-win32 under cygwin.
2565 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * lib/contrib/regex.c is not compiled on WIN32.
2569 * Added silc_net_get_socket_opt function to the
2570 lib/silcutil/silcnet.h.
2572 * Added includes/silcwin32.h for WIN32 specific includes
2575 * Do not use ptime structure or any of the posix process
2576 functions on WIN32 in lib/silccrypt/silrng.c.
2578 * Added silc_gettimeofday to provide generic function
2579 for struct timeval on all platforms. Added the function
2580 to lib/silcutil/silcutil.h.
2582 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2585 library as they clearly belong there. As a plus side we
2586 can make the actual socket connection routines platform
2589 Added also new generic function silc_socket_read and
2590 silc_socket_write (that used to be silc_packet_[read/write].
2591 The implementation of these are platform specific.
2593 * Added WIN32 specific routines of silc_socket_[read/write]
2594 to lib/silcutil/win32/silcwin32sockconn.c.
2596 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2598 * Added preliminary support for native WIN32 compilation under
2599 cygwin (using the -mno-cygwin option for GCC) to the
2600 ./configure.in.pre. The --with-win32 now prepares the
2601 compilation for native WIN32.
2603 * Rewrote the SILC Scheduler interface in the file
2604 lib/silcutil/silcschedule.h. The scheduler is now context
2605 based and does not have anymore any global static scheduler.
2606 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2607 and created lib/silcutil/win32 directory for WIN32 based
2610 * Added Unix specific network routines to the
2611 lib/silcutil/unix/silcunixnet.c and the old
2612 lib/silcutil/silcnet.c includes now only generic routines.
2614 Added WIN32 specific network routines to the
2615 lib/silcutil/win32/silcwin32net.c.
2617 * Added Unix specific utility functions from the
2618 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2620 * Added WIN32 SILC Scheduler to the file
2621 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2624 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Do not handle JOIN notify in the server if the target client
2627 is not registered (idata->registered == FALSE). The affected
2628 file is silcd/packet_receive.c.
2630 * Update the nickrec->founder in event_cumode in the Irssi SILC
2631 client. Affected file irssi/src/silc/core/silc-channels.c.
2633 * Fixed the CUMODE_CHANGE notify handling in the server when
2634 server and router are announcing their clients on channels.
2635 Now the mode changes are saved and notified correctly. The
2636 affected file is /silcd/packet_receive.c.
2638 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2639 They really did not replace the cache entry in the ID Cache.
2640 Now they do that. Affected file silcd/idlist.c.
2642 * Fixed the KICK notify handling in the Irssi SILC client to
2643 update the channel records so that the kicked client does not
2644 appear to be on the channel. The affected file is
2645 irssi/src/silc/core/silc-channels.c.
2647 * Always update the conn->current_channel when executing command
2648 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2650 * Fixed the KILL notify handling in Irssi SILC client to remove
2651 the killed client on all channels.
2653 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Fixed the silc_parse_command_line to remove extra spaces
2656 from the start and end of the arguments. Affected file is
2657 lib/silcutil/silcutil.c.
2659 * Cancel and free any active protocol in the function
2660 silc_server_close_connection. Affected file silcd/server.c.
2662 * Cancel and free any active protocol in the function
2663 silc_client_close_connction. Affected file is
2664 lib/silcclient/client.c.
2666 * Do not execute the KILL command for clients that are in
2667 history (ie. they are not in the network). Affected file is
2670 * Fixed KILL notify handling, client does not crash anymore.
2671 Affected file irssi/src/silc/core/silc-channels.c.
2673 * Reduced the default packet buffer size from 2048 to 1024 in
2674 lib/silccore/silcpacket.c.
2676 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2677 counter to the SKE context that is incresed when the SKE library
2678 performs async operation outside the library. If the outside
2679 process frees the SKE context and FREED status will be set
2680 and the library will detect after the sync operation that the
2681 libary is freed. The affected files are
2682 lib/silcske/silcske[_status].[ch].
2684 * Resolve the client entry information in the function
2685 silc_client_channel_message to assure that NULL pointer is not
2686 passed as client entry to the application. */
2688 * Fixed the task timeout calculation to assure that there is
2689 never negative timeouts. The affected file is
2690 lib/silcutil/silcschedule.c.
2692 * Fixed the channel user mode notification sending in server.
2693 It was sent point-to-point to the router (or to server by router)
2694 but it needs to be destined to a channel. The routines now
2695 supports sending the channel user mode notifys to the channels
2696 when announcing clients and channels. Affected files are
2697 silcd/server.c and silcd/packet_receive.c.
2699 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2700 It did not actually replace the old channel entry in the cache.
2701 Affected file lib/silcclient/client_notify.c.
2703 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * Fixed a possible crash in silc_packet_send_prepare. It now
2706 assures always that there is enough space in the buffer and
2707 at the tail area of the buffer (for MAC).
2709 Fixed the inbound buffer reallocation in silc_packet_read.
2710 It was old code and did not handle the reallocation correctly.
2713 The affected file is lib/silccore/silcpacket.c.
2715 * Fixed buffer overflow in silc_parse_nickname in the file
2716 lib/silcutil/silcutil.c.
2718 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * make install generates new server keys only if there is not
2723 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2726 Added check that if the NOREPLY is set then we will not send
2727 the away message. This avoids infinite loop of away messages
2728 if both clients are away. The affected file is
2729 lib/silcclient/client_prvmsg.c.
2731 * Fixed client crash if /NICK was given without arguments.
2732 Affected file lib/silcclient/command.c.
2734 * Server does not send the invite list in INVITE command back
2735 to the client if the list was not altered. Added this notion
2736 to the protocol spec as well. Affected file silcd/command.c.
2738 Fixed possible crash in INVITE command by checking the
2739 value of silc_server_get_client_route command.
2741 * Fixed the INVITE notify type handling. The arguments are now
2742 taken in correct order and client does not crash. The affected
2743 file is irssi/src/silc/core/silc-channels.c.
2745 Removed the "Inviting xxx to channel" message from the
2746 client library away and let the application handle it.
2747 Affected file lib/silcclient/command.c. Added that message
2748 to Irssi SILC client's message formats.
2750 * Fixed CMODE command crash in client. It now checks the
2751 amount of arguments correctly and does not crash. The affected
2752 file is lib/silcclient/command.c.
2754 * Do not create new channel automatically in silc_channels_join
2755 but check whether the channel by that name already exists.
2756 Affected file irssi/silc/core/silc-channels.c.
2758 * Do not send the SERVER_SIGNOFF to router if the disconnected
2759 entity was the router. Affected file silcd/server.c.
2761 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2762 SILC client as it was missing from there.
2764 Added the handling of the KICK notify to the Irssi SILC client
2765 as it was missing. Added "you have been kicked" message to
2766 Irssi SILC client's message modules formats.
2768 Added the handing of the KILL notify to the Irssi SILC client
2769 as it was missing. Added the kill message module formats
2772 The affected file is irssi/src/silc/core/silc-channels.c.
2774 * The router did not save the channel mode the server announced.
2775 Affected file silcd/packet_receive.c.
2777 * Fixed a possible crash in INFO command in server. If the
2778 server did not provide the server info it crashed. Affected
2779 file silcd/command.c.
2781 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * Fixed the GETKEY command in the server to check also the
2784 global list. Otherwise the GETKEY would not work correctly
2785 in normal SILC server. Affected file silcd/command.c.
2787 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Fixed GETKEY crash, it crashed if the command did not succseed.
2791 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2794 is now real and not just an macro interface to GMP.
2796 Removed the entire GMP from the source tree and imported new
2797 NSS MPI library instead. Reason for removing GMP is that it is
2798 extremely large and compiles extremely slow. The NSS MPI
2799 is only a few files and compiles in less than 10 seconds.
2800 The speed is also about the same as GMP. The MPI is imported
2801 to lib/silcmath/mpi.
2803 If the system has GMP installed we will still use the GMP.
2804 If it is not then the NSS MPI will be compiled.
2806 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2808 * Merged a long nickname (127 characters long) crash bugfix from
2809 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2811 * Merged a freed memory reference bugfix from Irssi CVS tree.
2812 Affected file irssi/src/core/commands.c.
2814 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Added the server's public key sving and verification to the
2817 server when performing the SKE. This was missing and the
2818 remote server's (or router's) public key was accepted without
2819 checking whether we have it previously or trust it at all.
2820 Affected file silcd/protocol.c.
2822 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Check in the silc_server_timeout_remote if protocol is active
2825 and make sure that the protocol's final callback is called so
2826 that all memory if freed. Affected file silcd/server.c.
2828 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * silc_server_whois_send_reply crashed the server if the nickname
2831 was 127 characters long. Affected file silcd/command.c.
2833 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Added sanity check to the silc_server_new_client. If the hostname
2836 is provided inside username then check that the provided hostname
2837 really is the same as the resolved one. If the hostname was not
2838 resolved then check it from the public key. Affected file is
2839 silcd/packet_receive.c.
2841 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2842 if the server disconnected us and the connection is not valid
2843 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2845 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2846 the library to the lib/silcutil/silcutil.[ch].
2848 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Close log file after open. Affected file
2851 lib/silcutil/silclog.c.
2853 * Check whether sock == NULL in silc_client_send_packet and return
2854 if it is. Affected file lib/silcclient/silcclient.c.
2856 * Check rec->entry == NULL in the Irssi SILC Client before
2857 sending the channel message. Affecte file is
2858 irssi/src/silc/core/silc-servers.c.
2860 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Merged a splitted window bugfix from Irssi CVS tree. The
2863 affected file is irssi/src/fe-text/textbuffer-view.c.
2865 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2866 It did not print nickname.
2868 * Improved the distributions system a bit.
2870 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2873 irssi/src/fe-text/gui-window.c.
2875 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2876 to in-active server. The affected file is
2877 irssi/src/silc/core/client_ops.c.
2879 * Resolve the client in USERS command reply if the entry does
2880 not have username resolved. The affected file is
2881 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2882 command to WHOIS command to really resolve stuff. The USERS
2883 is not used any more in any critical section so WHOIS can
2884 be used even though it might be slower than IDENTIFY.
2886 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2889 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Changed the protocol API a bit more consistent in the
2892 lib/silccore/silcprotocol.[ch].
2894 * Changed the following headers to ROBODoc format:
2896 lib/silccore/silcpayload.h
2897 lib/silccore/silcprotocol.h
2898 lib/silccore/silcsockconn.h
2900 All core library headers are now formatted.
2902 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Fixed a bug in Irssi SILC client; do not show that you are
2905 server/router operator if you really are not. Affected file is
2906 irssi/src/silc/core/client_ops.c.
2908 * Renamed silc_command_free_payload to silc_command_payload_free.
2909 Affected file lib/silccore/silccommand.h
2911 * Added silcmath.h to include the prototoypes of various routines
2912 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2915 * Changed the following headers to ROBODoc format:
2917 lib/silccore/silcchannel.h
2918 lib/silccore/silccommand.h
2919 lib/silccore/silcid.h
2920 lib/silccore/silcidcache.h
2921 lib/silccore/silcmode.h
2922 lib/silccore/silcnotify.h
2923 lib/silccore/silcpacket.h
2924 lib/silcmath/silcmath.h
2926 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Added checking to the server code not to start the server if
2929 ciphers and stuff are not configured properly. Affected files
2930 silcd/serverconfig.[h] and silcd/server.c.
2932 * Changed the layout of the header files of the public interfaces
2933 in the SILC libraries. The new layout supports ROBODoc
2934 documentation tool (and some others) so that it is easy to create
2935 a library reference manual. All the other headers and source
2936 code must still follow the CodingStyle document. Also source
2937 code must not include these ROBODoc stuffs, only the headers.
2938 Furthermore, all public interface headers must now be named
2939 by using `silc' prefix, example: silcapi.h, silccipher.h.
2940 Some files were renamed due to this. All the other headers
2941 must not be used as public interfaces. I will update the
2942 CodingStyle document later. Changed following headers, so far:
2944 lib/silcclient/silcapi.h
2945 lib/silccore/silcauth.h
2946 lib/silccore/silcprivate.h
2947 lib/silccrypt/silcdh.h
2949 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2953 * Removed silc_client_packet_send_flush from the client library
2954 as it is not needed. Affected file lib/silcclient/client.[ch].
2956 * Added printing of message of unresolved authentication method
2957 to the Irssi SILC client. Added it to the module formats.
2958 Removed the same message from the client library.
2960 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Added new distribution feature, DISTLABEL. Every distribution
2963 can define own preprocessor label that can be used in the
2964 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2965 file distributions, acconfig.h.pre and prepare.
2967 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2969 * Added Makefile.defines_int to include the actual definitions
2970 for Makefile.defines.in. Tested the new distribution system,
2971 created distributions and tested installation.
2973 * Added AWAY message printing to the Irssi SILC client. Added
2974 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2976 * Added SCONNECT command to call the SILC's CONNECT command.
2977 Cannot use CONNECT directly since Irssi uses that internally.
2978 Affected file irssi/src/silc/core/silc-servers.c.
2980 Added ACTION local command. It is same as ME command but takes
2981 the channel as mandatory argument.
2983 Rewrote some of the Irssi's help files to suite for SILC
2986 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Added Makefile.defines[.in] that should for now on be included
2989 in all Makefile.am file in the source tree. That file includes
2990 all common compilation definitions for SILC source tree.
2992 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Minor changes to the ./prepare script to change the package
2995 name according the distribution name to the configure.in.
2997 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Created new distribution system. Added file `distributions'
3000 that defines all the distributions that can be created out of
3001 the SILC source tree. The ./prepare script now reads that
3002 file to determine how to prepare the distributions. The
3003 first argument to the ./prepare is the name of the distribution
3004 and second is the version of the distribution. If given
3005 without arguments it creates the default (toolkit) distribution
3006 with the default version (defined in ./prepare).
3008 All Makefile.am files that are subject to the distributions
3009 are now named as Makefile.am.pre. These are ./Makefile.am
3010 and lib/Makefile.am. Others may be changed later.
3012 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Added invite list, ban list, some key management and connection
3015 error message printing to module formats in the Irssi SILC client.
3017 * Added new silc_client_set_away_message to set the away message
3018 that is back to the person who sent private message. The
3019 affected file lib/silcclient/silcapi.h and the
3020 lib/silcclient/client_prvmsg.c.
3022 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Fixed the private message sending in the Irssi SILC client,
3025 added local command KEY to the Irssi SILC client.
3027 Added key management and key agreement message formats to the
3028 irssi/src/fe-common/silc/module-formats.[ch].
3030 Added USERS (alias WHO) printing, server/router operator
3031 indication and LIST command printing to the module formats.
3033 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Fixed channel joining notify handling, cumode notify handling
3036 from Irssi SILC client.
3038 * Added SILC specific module-formats to the Irssi SILC client so
3039 that SILC specific message hilighting, colors etc is possible.
3040 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3042 Added channel mode, channel user mode, actions, notices,
3043 whois and whowas printing to the the module-formats.c.
3045 * Fixed a bug in channel deletion in the server. The channel
3046 is not left to the cache even if the channel founder auth mode
3047 is set when there are no users anymore on the channel. Affected
3048 file silcd/server.c.
3050 * The silc_net_localhost now resolves the entire hostname including
3051 the domain name. Affected file lib/silcutil/silcnet.c.
3053 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Changed the ask_passphrase client operation to be ascynchronous.
3056 It has now a completion callback and a context that the
3057 application must call after it has got the passphrase from
3058 the user. Affected files lib/silcclient/silcapi.h,
3059 lib/silcclient/protocol.c, lib/silcclient/command.c and
3062 Added SilcAskPassphrase callback that the application calls
3063 to deliver the passphrase to the library.
3065 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3066 The public key verification and especially a certificate
3067 verification is asynchronous procedure.
3069 Added new SILC_SKE_STATUS_PENDING status to indicate the
3070 request is pending and a callback will be called to finalize
3073 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3074 indicate that remote end did not send its public key (or
3075 certificate), even though we require it. Added check for this
3076 condition in the SKE. This was a security bug, now fixed.
3078 Defined new SilcSKEVerifyCbCompletion callback that is called
3079 when the verification process is completed.
3081 The affected files lib/silcske/silcske_status.h and
3082 lib/silcske/silcske.[ch].
3084 * Changed the verify_public_key client operation to be async
3085 as well. Defined SilcVerifyPublicKey callback that is used to
3086 indicate the success of the public key verification process.
3088 Changed the server and client to use the new async client
3091 * Changed the Irssi SILC client's internal scheduler to be called
3092 twice as many times as it used to be. As a result the client
3093 should be a bit faster now. Affected file is
3094 irssi/src/silc/core/silc-core.c.
3096 * Added support to Irssi SILC client of asynchronous public key
3097 verification and passphrase inquiry. Affected file is
3098 irssi/src/silc/core/silc-core.c.
3100 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3102 * Do not say "You have left channel %s" in client library.
3103 Moved it to the application. Affected files are
3104 lib/silcclient/command.c and silc/client_ops.c.
3106 * Fixed silc_client_get_clients. Command context was not
3107 duplicated and was freed memory in the callback. Affected
3108 file lib/silcclient/idlist.c.
3110 * Do not say "you are now talking..." on JOIN command in the
3111 client library. The appliation must handle it.
3113 * Do not say ".. changed topic to" in command reply in the
3114 client libary. The application must handle it.
3116 * Fixed TOPIC command sending in the client library.
3118 * Fixed a memory leak in silc_client_command_free in the file
3119 lib/silcclient/command.c.
3121 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3123 * Imported a modified version of Irssi client to the source tree.
3124 The Irssi will be used to create a new client called
3125 Irssi SILC. Imported to irssi/.
3127 Added silc_core_init_finish function to the Irssi. Affected
3128 file irssi/configure.in.
3130 A lot changes in the Makefile.ams around the irssi tree.
3132 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Do not rehash if the new size is same as the old size of the
3135 hash table, in the silc_hash_table_rehash*. The affected file
3136 lib/silcutil/silchashtable.c.
3138 * Replaced hash_table_del_by_context calls from the server
3139 (when channel->user_list and client->channels) to the
3140 hash_table_del as it is sufficient and faster.
3142 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Added silc_hash_table_list, silc_hash_table_get and the
3145 SilcHashTableList structure to provide an alternative way to
3146 traverse the hash table. The affected files are
3147 lib/silcutil/silchashtable.[ch].
3149 * Changed the server's idlist routines to use the hash table
3150 routines to optimize the code.
3152 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Replaced the client entry's `channel' list and channel entry's
3155 `user_list' list to hash tables for optimized lookup. Changed
3156 the code to use the hash table interface around the code.
3157 Affected file lib/silcd/idlist.[ch].
3159 * Added `auto_rehash' boolean argument to the function
3160 silc_hash_table_alloc to indicate whether the hash table should
3161 auto-rehash when it thinks is appropriate time. It will
3162 increase the hash table size if the there is twice as much
3163 entries in the table than the size of the table, and will
3164 decrease the size if there are twice as less entries than
3165 the size of the table.
3167 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3171 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * silc_idcache_purge_by_context deletes the entry now by context
3174 as it is supposed to do. Affected file lib/silccore/idcache.c.
3176 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3177 client is not anymore valid (WHOWAS givens the info) and not
3178 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3180 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Removed the `data' and `data_len' arguments from the ID Cache
3183 interfaces and added `name' argument. ID Cache does not handle
3184 anymore the binary data only a names associated with given ID.
3186 * When hashing a Client ID with silc_hash_id the entire ID is
3187 not hashed anymore, instead only the hash of the Client ID is
3188 hashed. This way we can access the Client ID from the cache
3189 with Client ID but with the hash of the ID (which is a hash of
3190 the nickname) as well without any difference in performance.
3192 Added also silc_idcache_find_by_id_one_ext to do one on one
3193 searching when we have the actual ID. Added also function
3194 silc_hash_client_id_compare. The affected files are
3195 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3197 * When hashing the name associated with a ID it is always done
3198 in lowercase. This way we can access the cache without worrying
3199 about case-sensitivity, even though, for example nicknames are
3202 * Fixed a bug in server with channel message sending. It put
3203 wrong ID type as destination ID. The affected file
3204 silcd/packet_send.c.
3206 * silc_idcache_del_by_context now deletes from all hash tables
3207 by context. Affected file lib/silccore/idcache.c.
3209 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Changed the client library to use the new ID Cache interface.
3212 Changes around the source tree.
3214 * Added silc_hash_table_rehash_ext to rehash with specific
3215 hash function. Affected file lib/silcutil/silchashtable.[ch].
3217 * Added silc_hash_string_compare to compare two strings in the
3218 hash table. Affected file lib/silcutil/silcutil.[ch].
3220 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Added new function silc_idcache_del_by_context into the
3223 lib/silccore/idcache.[ch].
3225 * Changed the server's ID list routines to use the new ID Cache
3226 interface. Changes around the source tree.
3228 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Added silc_hash_table_del[_by_context]_ext functions in to the
3231 lib/silcutil/silchashtable.[ch].
3233 Removed silc_hash_table_find_all* routines and added new
3234 silc_hash_table_find_foreach to replace them.
3236 Added silc_hash_table_replace_ext function as extended
3237 replacing function. Separated the simple hash table interface
3238 from the extended hash table interface in the file
3239 lib/silcutil/silchashtable.h.
3241 * Fixed minor bugs and changed it to use some of the new
3242 hash table functions in lib/silccore/idcache.c
3244 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Added new function silc_hash_table_find_all to return all keys
3247 in the hash table by the specified key. As the hash table is
3248 collision resistant it also makes it possible to have several
3249 duplicate keys in the hash table. This function may be used to
3250 find all of the keys from the hash.
3252 Added user_context arguments to the SilcHashFunction,
3253 SilcHashCompare and SilcHashDestructor to deliver user specified
3256 Added new fuctions silc_hash_table_find[_all]_ext to do
3257 extended lookup with specified hash and compare functions and
3258 specified user contexts.
3260 Added new function silc_hash_table_add_ext to add the key
3261 with specified hash function and user context.
3263 Added new function silc_hash_table_foreach to traverse all
3264 entrys in the hash table. Added SilcHashForeach callback
3267 Added new function silc_hash_table_del_by_context to delete
3268 the entry only if the context associated with the key matches.
3270 Affected files are lib/silcutil/silchashtable.[ch].
3272 * Removed silc_hash_[server/client/channel]_id and added just
3273 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3274 silc_hash_id_compare to compare two ID's using as the hash table
3275 comparison function. Added also silc_hash_data to hash
3276 binary data and silc_hash_data_compare to compare it.
3278 * Removed silc_idlist_find_client_by_hash as it is not needed
3279 anymore. Affected file silcd/idlist.[ch].
3281 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3282 to use internally the SilcHashTable. The new ID Cache is a lot
3283 faster than the old one. Some of the ID Cache interface was also
3284 rewritten and obsolete and stupid functions were removed.
3286 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Added entry_count field to the SilcHashTable to keep the number
3289 of the entries in the table. Implemented the function
3290 silc_hash_table_rehash. Added new function
3291 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3293 Fixed a minor bug in silc_hash_table_free.
3295 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3296 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3297 into the lib/silcutil/silcutil.[ch].
3299 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Implemented a collision resistant hash table into the
3302 lib/silcutil/silchashtable[ch]. See the header and the source
3303 for the SilcHashTable API.
3305 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Merged dotconf version 1.0.2 into lib/dotconf.
3309 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3311 * Do not compile anything in lib/silcsim/* if the SIM support
3312 is not enabled. The tree should now compile without problems
3315 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * Compiled the SILC under cygwin. Compiled and tested briefly
3318 without problems. More tests needed. The SIMs didn't compile
3321 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3323 * Fixed possible crash in silc_get_username in the
3324 lib/silcutil/silcutil.c.
3326 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Fixed a va_arg in silc/client_ops.c.
3330 * Oops, RC5 routines were named AES and caused some problems
3331 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3333 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Added new SilcIDIP structure into the lib/silccore/id.h and
3336 replaced the old `ip' fields from all SILC ID's to that type.
3337 This is a step towards IPv6 support.
3339 The silc_id_get_len takes now the ID as an extra argument.
3340 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3341 both IPv4 and IPv6 based ID's.
3343 The affected files are lib/silccore/id.[ch] and other files
3344 around the tree using these routines.
3346 * Removed the ID length arguments in server from various
3347 silc_server_send_notify_* routines -> they are not needed
3350 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Fixed memory leak in silc_encode_pem_file in the file
3353 lib/silcutil/silcutil.c.
3355 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Check minor version as well in the SKE. Affected files are
3358 silcd/protocol.c and lib/silcclient/protocol.c.
3360 * Added --identifier option to the server so that an identifier
3361 can be when creating the public key for the server. Affected
3362 file is silcd/silcd.c.
3364 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3365 lib/silccrypt/silcpkcs.c.
3367 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Register default ciphers and stuff when using -C option with
3370 the server. Affected file sildc/silcd.c.
3372 * Put back the servers public key filename format, it is better
3373 than the new one. For now, the client keys are saved with the
3374 new filename format. The affected file silc/client_ops.c.
3376 * Implemented the Cipher API for the rest of the ciphers that
3377 did not implement it or implemented it the wrong way.
3379 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Register default ciphers and stuff when using the -S option
3382 in the client. Affected file silc/silc.c. Same also when
3383 creating new key pair with -C option.
3385 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Fixed the silc_verify_public_key client operation function to
3388 save the public keys differently. The fingerprint is now
3389 used as filename and not the hostname. This way also the
3390 client keys are saved uniquely and not with hostnames. The
3391 affected file is silc/client_ops.c.
3393 * Trimmed the silc_hash_fingerprint function to remove extra
3394 whitespaces from the end of the fingerprint. The affected
3395 file is lib/silccrypt/silchash.c.
3399 * Added silc_cipher_register_default function to register all
3400 default ciphers. It can be used when configuration files
3401 does not exist and the application does not want any specific
3402 ciphers in any specific order.
3404 The SilcDList is now used as silc_cipher_list dynamically
3405 allocated cipher list. Removed the static list all together
3406 and now all ciphers must be allocated to the dynamic list.
3407 The silc_cipher_alloc routine was changed to check only the
3410 All silc_cipher_* routines that used to return int returns
3413 The affected files lib/silccrypt/silccrypt.[ch].
3415 * The same thing was done to silc_hash_* as for silc_cipher_*
3416 routines. Affected files lib/silccrypt/silchash.[ch].
3418 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3419 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3420 Added also silc_pkcs_[un]register[_default] functions.
3421 Removed the data_context from the PKCS API.
3423 * Added silc_hmac_register_default function to register default
3424 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3425 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3426 to unregister all hmacs at once.
3428 * Register the default ciphers, hash functions, PKCSs and HMACs
3429 if client's configuration file does not exist. The affected
3432 * The client did not load the hash functions from the SIM
3433 modules at all. Added support for this. Affected file is
3434 silc/clientconfig.c.
3436 * When decoding public key with silc_pkcs_public_key_decode, check
3437 the supported algorithm only if PKCS are registered. Affected
3438 file lib/silccrypt/silcpkcs.c. The same was done with the
3439 silc_pkcs_private_key_decode.
3441 * Fixed the SILC List routines to keep the list always in order.
3442 It used to change the list's order when traversing the list but
3443 not it preserves the order. Affected file lib/trq/silclist.h.
3445 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Added the client library to use the SilcSocketConnection's
3448 reference counter (by silc_socket_dup) to prevent the bug that
3449 the socket object may be freed underneath async operation.
3451 * The name resolv library checking fixes in the configure.in.pre.
3454 * Created new version of the protocol drafts for future
3455 development. The -03 drafts are the ones that will be changed
3456 in the trunk now and the -02 will remain as they are.
3458 * Send list of CUMODE notifys to the router when announcing
3459 the channel users to the router. Affected file silcd/server.c.
3460 If the router receiving channel founder CUMODE for a channel
3461 that already has channel founder it will send CUMODE notify
3462 to the sender to remove the channel founder rights from the
3463 announced client. Affected file silcd/packet_receive.c.
3465 * The CUMODE notify may now use Server ID as well as the entity
3466 who changes the mode. Updated protocool specs.
3468 * Updated INSTALL and README files.
3470 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * New web pages in the http://silc.pspt.fi. The pages was
3477 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Implemented the [DenyConnectin] config section in the server.
3480 Added silc_server_config_denied_conn to check whether incoming
3481 connection is denied. Affected file silcd/serverconfig.[ch].
3483 * Do not check the ports when checking the incoming configuration
3484 data if the port is 0, meaning any. Affected file is
3485 silcd/serverconfig.c.
3487 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Fixed buffer overflow in silc_string_compare in the file
3490 lib/silcutil/silcutil.c.
3492 * Fixed double free in silc_server_command_leave in the file
3495 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Fixed the version checking in the server. Affected file is
3500 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Fixed the configuration data fetching when accepting new
3503 connections in the server. Affected file silcd/server.c.
3505 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Added `sender_entry' argument to the function
3508 silc_server_packet_relay_to_channel so that we can check
3509 whether some destination actually belongs to the same route
3510 the sender belongs (ie, we must not resend the packet to the
3511 sender). Affected file silcd/packet_send.[ch].
3513 * Added `servername' field to the SilcClientEntry in the server
3514 to hold the name of the server where client is from. Affected
3515 file is silcd/idlist.h.
3517 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3519 * Moved the channel message encrypting in the router betwen
3520 router connections from silc_server_channel_message to the
3521 silc_server_packet_relay_to_channel since we want to check
3522 whether we have anybody channel before encrypting anything.
3523 Affected files silcd/packet_[receive/send].c.
3525 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Fixed the [AdminConnection] server config section to support
3528 multiple entries. Affected file silcd/serverconfig.c.
3530 * Added support into the server to check the validity of the
3531 incoming connection before executing any KE or authentication
3534 * The connection configuration is now saved to the KE and
3535 connection auth protocol contexts and not fetched anymore in
3536 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3538 * The local hosts listenning address and port is also resolved
3539 now when starting the server. We want to have the socket object
3540 to include the real address and port for the listener. Added
3541 new function silc_net_check_local_by_sock into the files
3542 lib/silcutil/silcnet.[ch].
3544 * Fixed a broadcast bug in server -> do not broadcast if we
3547 * Fixed a routing bug. Do not route broadcast packets ever.
3548 Broadcast packets must be processed always and not routed since
3549 they may be destined to some other host than yourself and thus
3550 would get routed without no good reason. Affected file is
3553 * Added function silc_server_config_is_primary_route to check
3554 whether primary router connection has been configured (a router
3555 configuration that we are initiating). If there is not, we
3556 will assume that there is only two routers in the SILC network
3557 and we will use the incoming router connection as our primary
3558 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3560 * Changed the order of the broadcasting. Broadcast _after_ the
3561 packet has been processed not before. Affected file is
3564 * Fixed a [ClientConnection] parsing bug. The port was never
3565 parsed correctly thus resulting to port 0. Affected file
3566 silcd/serverconfig.c.
3568 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3569 argument and did not set the broadcast packet flag. Affected
3570 file silcd/packet_send.c. Fixed same bug in the function
3571 silc_server_send_notify as well.
3573 * If we receive NEW_ID packet for our own ID in the server, ignore
3576 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3580 * Removed the nickname from the Private Message Payload.
3581 Updated the code and the protocol specs.
3583 * Updated protocol specs for submitting to the IETF.
3585 * Tweaked the Random Number Generator a bit. Affected file
3586 lib/silccrypt/silcrng.c. Exported a new function
3587 silc_rng_[global]_add_noise which can be used to add more
3590 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Do not parse packets with different timeout when protocol
3593 is active -> may cause problem with rekey. Affected file
3596 * When server receives signoff notify it must not create
3597 new channel key if the client is on any channels since the
3598 sender of the signoff notify will create it.
3600 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Added printing of error messages during SKE protocol from the
3603 failure packet sent by server during SKE. Affected file
3606 * Removed the client's failure_callback handling with timeout
3607 and handle it immediately when received.
3609 * The SKE library returned wrong type in SUCCESS and FAILURE
3610 packets. They must be 32 bit MSB not 16 bit MSB.
3612 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Ok, rewrote the logic of the re-key and now it seems to work.
3615 I tested it on high traffic with frequent re-keys without
3616 problems. Added hmac_receive (and renamed hmac to hmac_send)
3617 in SilcClientConnection in lib/silcclient/client.h and
3618 in SilcIDListData in silcd/idlist.h. Also, removed the
3619 SilcPacketParserContext's cipher and hmac fields as they are
3620 not needed anymore and actually caused some problems when
3621 the ciphers and hmac's changed underneath the packet parser.
3623 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * If re-key protocol is active then process the incoming packets
3626 synchronously since we must assure that icoming packets encrypted
3627 with the old key is processed before the new keys is set to
3628 use. This is true other packets than for REKEY packets.
3629 Affected file silcd/server.c. The same was done to client library
3630 as well, affected file lib/silcclient/client.c.
3632 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Fixed bug in client and server to accept the force send if
3635 the packet is send from silc_[server/client]_packet_process
3636 function. Otherwise the packets are never delivered, oops.
3638 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Disable force sending of packets when REKEY protocol is active.
3641 We must assure that no packet is sent directly when rekey is
3642 performed. All packets must be sent through packet queue.
3643 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3644 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3645 function is silc_[server/client]_packet_send_real to check
3648 * Replaced the SIM paths from example config files to
3649 /usr/local/modules. Also, make install creates now
3650 /usr/local/silc/logs directory to hold all the SILC server
3653 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Made the configure.in.pre work on Solaris. Patch by salo.
3657 * Made all ciphers compatible with non-x86 machines. Defined
3658 CBC mode macros into lib/silccrypt/ciphers_def.h.
3660 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Fixed the make install.
3664 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * When MAC computation fails the silc_packet_decrypt returned 0
3667 even though it was supposed to return -1. Fixed this. The
3668 affected file is lib/silccore/silcpacket.c.
3670 * Do not replace the config files in /etc/silc (in make install)
3671 if they already exist. Affected file ./Makefile.am.
3673 * Do not send re-key packets immediately but through packet queue.
3674 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3676 * Changed silc_net_check_host_by_sock to return FALSE if the
3677 IP/DNS could not be resolved. Though, it returns the IP address
3678 now even if it could not resolve it (but returns also FALSE).
3679 Affected file lib/silcutil/silcnet.[ch].
3681 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Added silc_pkcs_decode_identifier to decode the public key's
3684 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3685 Added also silc_pkcs_free_identifier. Added also new context
3686 SilcPublicKeyIdentifier.
3688 * Added -S option to the silc client. It is used to dump the
3689 contents of the specified public key file.
3691 * Changed the PKCS api to return the public key length when
3692 setting the public key.
3694 * Fixed a fatal bug in the public and private key file loading.
3695 Affected file lib/silccrypt/silcpkcs.c.
3697 * Execute the packet parsing for client with zero (0) timeout
3698 if the protocol is active. Affected file silcd/server.c.
3700 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Made the key generation options to the silcd program. Added
3703 -C option, equivalent to client's option.
3705 * Added new [ServerKeys] config section to the server. It
3706 configures the server's public and private key.
3708 * Defined generic Public Key Payload into the protocol
3709 specification to send specific type of public keys and
3712 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3713 public key or certificate.
3715 * Implemented the GETKEY command to the server and to the
3716 client library and on user interface.
3718 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Made preliminary `make install' work.
3722 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * Added SilcServerRekey context into silcd/idlist.h.
3726 * Added the PFS support as defined in the specification to the
3727 SKE protocol. Affected files lib/silcske/*.c.
3729 * Added `ske_group' field to the SilcServerRekey context to hold
3730 the number of the SKE group that is used with PFS in re-key.
3731 Affected file silcd/idlist.h.
3733 * Added PFS re-key support to the server. Affected file is
3736 * Added silc_protocol_cancel to cancel execution of the next
3737 state of the protocol. Affected file is
3738 lib/silccore/silcprotocol.[ch].
3740 * Added the re-key support with and without PFS to the client
3741 library. Re-key is performed once in an hour, by default.
3743 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3744 Added silc_client_rekey_callback and silc_client_rekey_final.
3745 Affected files are lib/silcclient/protocol.[ch] and
3746 lib/silcclient/client.[ch].
3748 * Removed the `hmac_key' and `hmac_key_len' fields from the
3749 SilcClientConnection structure; not needed. Affected file is
3750 lib/silcclient/client.h.
3754 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Do not ask whether user wants to use the negotiated private key
3757 for private messages, just use it. Affected file is
3758 silc/local_command.c.
3760 * Added `send_enc_key' and `enc_key_len' fields to the
3761 SilcIDListData structure since they are needed in the re-key
3762 phase. Affected file is silcd/idlist.[ch].
3764 * Implemented the simple re-key protocol into the server.
3765 Affected files silcd/server.c and silcd/protocol.[ch]. The
3766 re-key will be performed once in an hour, by default.
3768 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3769 Added silc_server_rekey, silc_server_rekey_callback and
3770 silc_server_rekey_final.
3772 * Removed Tunneled flag from the protocol. Updated the code
3773 and the specifications.
3775 * Adde `pfs' field to the SilcIDListData to indicate whether
3776 the PFS is to be performed in the re-key. Affected file is
3779 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3781 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3782 int64 of at least the xintXX size. If void * is less that 4
3783 bytes uint32 * will be used. Defined bool as boolean.
3785 * Changed _ALL_ unsigned long and unsigned int to uint32,
3786 unsgined short to uint16 in the source tree.
3788 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3789 not handle clients that has entry->data.registered == FALSE.
3790 They are not in the network anymore. Affected file is
3793 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Implemented the sending of the SERVER_SIGNOFF notify in the
3796 server. Affected file is silcd/server.c.
3798 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3799 Added also silc_notify_payload_encode_args into the
3800 lib/silccore/silcnotify.[ch].
3802 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3803 Affected file silcd/packet_receive.c.
3805 * Implemented the SERVER_SIGNOFF notify handling in the client
3806 library. Affected file lib/silcclient/client_notify.c. Also,
3807 implemnted the printing of the SERVER_SIGNOFF info to the
3808 application. Affected file silc/client_ops.c.
3810 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3811 if the deleting was successful. Affected file silcd/idlist.[ch].
3813 * Added support for public key authentication in the connection
3814 authentication protocol in the client library. Affected file
3815 lib/silcclient/protocol.c.
3817 * Changed the server's silc_idlist_get_clients_by_* interface
3818 to support already allocated array so that new entries may be
3819 added to pre-allocated array. Affected file silcd/idlist.[ch].
3820 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3821 and command replies.
3823 * All command reply functions in the server now calls the
3824 pending command callback even if error occured. This way the
3825 error will be delivered to the client as well. Affected files
3826 silcd/command.c and silcd/command_reply.c.
3828 * Fixed INFO command to return local server's info if no server
3829 was provided. Affected file lib/silcclient/command.c.
3831 * Removed RESTART command for good. Updated the code and the
3834 * Rewrote parts of the task system. It is a bit simpler now.
3835 Removed unsued task priorities. The affected files are
3836 lib/silcutil/silctask.[ch].
3838 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Moved the USERS printing from the library to the application.
3841 Affected files lib/silcclient/command.c and silc/client_ops.c.
3843 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Added channel key re-key support. The re-key is perfomed
3848 only by the router and is done once in an hour. Added `rekey'
3849 field to the SilcChannelEntry in the server. Affected files
3850 silcd/server.c and silcd/idlist.h.
3852 * Added silc_task_unregister_by_context into the file
3853 lib/silcutil/silctask.[ch].
3855 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Added SILC_UMODE_GONE mode to indicate when the client is not
3858 present in the SILC network. Added also support to the local
3859 command AWAY that will set this mode. Added support of showing
3860 "xxx is gone" in WHOIS command. The USERS command shows the
3861 gone status as well.
3863 * Fixed setting server and router operator privileges in the
3864 server's UMODE command. Affected file silcd/command.c.
3866 * Merged the SKE KE1 and KE2 payloads into one payload. The
3867 new KE payload is equivalent to the old KE2 payload.
3869 Cleaned up the SKE Start Payload parsing. It now uses the
3870 simple buffer unformatting to do the parsing. A lot faster
3873 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3874 to the SKE that is used to indicate whether both of the SKE
3875 parties should perform authentication. By default only the
3876 responder performs authentication. By setting this flag also
3877 the initiator must do authentication. By default it is unset
3878 since in normal SKE case, client to server connection, only
3879 the responder should do authentication. When doing SKE between
3880 two clients both should perform authentication. Updated the
3881 code and the protocol specs.
3883 * A little fix to IDENTIFY command in the server. Search the
3884 client first by hash not nickname. Affected file is
3887 * Fixed the silc_client_close_connection to support closing
3888 the client to client connections wihtout deleting too much
3889 data. Affected file lib/silcclient/client.c.
3891 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3892 are received if protocol used to be active but is not anymore
3893 the application would crash due to NULL pointer dereference.
3894 Affected files silcd/server.c and lib/silcclient/client.c.
3896 * Added `hash' field to the SilcClientConnection to include
3897 the hash function negotiated in the SKE protocol.
3899 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3900 to set the channel founder authentication data. A client can
3901 claim the founder rights later by providing the authentication
3902 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3903 This way the channel founder can regain the channel founder
3904 privileges even it is left the channel. This works only on
3905 local server and the client must be connected to the same
3906 server to be able to regain the founder rights. Updated the
3907 protocol specs accordingly.
3909 Added support to the CMODE command in the client to set the
3910 founder auth data. Read the README to see how to set it.
3912 Added support to the CUMODE command to claim the founder
3913 rights. Read the README to see how to do it.
3915 Added support for the founder authentication to the Channel
3916 Entry in the server. Affected file silcd/idlist.h.
3918 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3919 server's CMODE command. Affected file silcd/command.c.
3921 * Added the following new functions into lib/silccore/silcauth.[ch]:
3922 silc_auth_get_method and silc_auth_get_data.
3924 * The server now saves the remote hosts public key to the
3925 SilcIDListData pointer. Affected file silcd/protocol.c.
3927 * The normal server now does not remove the channel entry from
3928 the cache if the founder authentication data is set. It used
3929 to remove it if the founder was the last one on the channel on
3930 the server and left the channel. The auth data is saved and
3931 if the channel is re-joined later the old entry is used with
3932 the old auth data. Affected files silcd/command_reply.c and
3935 * Removed the `pkcs' field from the SilcIDListData structure
3936 in the server; it is not used. Affected file silcd/idlist.h.
3938 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Fixed packet processing on slow links. Partial packets were
3941 never re-processed because the incoming data buffer was cleared
3942 by the application. Application must not directly clear the
3943 sock->inbuf, the packet processing routines handle it. Fixed
3944 this in client library and in server.
3946 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Fixed the WHOIS and IDENTIFY send reply function to really
3949 check whether to send list or just one entry. Affected file
3952 * Cleaned up the LEAVE command's channel key distribution. The
3953 affected file silcd/command.c.
3955 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3956 can enforce the channel mode as well. In that case the ID
3957 includes the ID of the server. The code now enforces the
3958 mode change if the router have different mode than the server.
3960 * The notify client operation with CMODE_CHANGE notify can now
3961 return NULL client_entry pointer if the CMODE was not changed
3962 by client. Application must check for this.
3964 * Added <Server ID> argument to INFO command to support server
3965 info fetching by Server ID.
3967 * Added silc_server_announce_get_channel_users to get assembled
3968 packets of channel users of the specified channel. Affected
3969 file silcd/server.[ch].
3971 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3972 was freed underneath the ID Cache.
3974 * Re-announce clients when the server received CHANNEL_CHANGE
3975 notify from the router. Affected file silcd/packet_send.c.
3977 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3980 crashed since it did not handle the fact that there is no cipher
3981 called "3" and didn't check the error condition. Now fixed.
3983 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3984 flag. It can be used to send message requests.
3986 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Implemented the RESTART command in the client.
3990 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3991 notice type messages. Added notice printing to the user
3994 * The channel keys are not re-generated if the channel's mode
3995 is PRIVKEY, ie private key on the channel exists. Affected
3996 files silcd/server.c and silcd/command.c.
3998 * Fixed a little bug in channel message delivery when channel
3999 private keys are set in the server. Affected file is
4000 silcd/packet_send.c.
4002 * Changed the setting on channel->on_channel = TRUE from the
4003 silc_client_save_channel_key to the JOIN command reply. The
4004 key payload is not received if the private channel key is set.
4005 Affected file lib/silcclient/command_reply.c and the
4006 lib/silcclient/client_channel.c.
4008 * When the CMODE_CHANGE notify is sent and the channel private
4009 key mode is removed the channel key must be re-generated in
4010 other cells as well. Added this support for the router in the
4011 silcd/packet_receive.c.
4013 * Added new local command NOTICE to send notice message on
4014 channel. Affected file silc/local_command.[ch].
4016 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4018 * Added new local command ME to the client. It is used to send
4019 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4020 some action. Affected file silc/local_command.[ch].
4022 * Changed channel_message and private_message client operations
4023 to deliver the message flags to the application. Added also
4024 the `flags' arguments to the silc_client_send_channel_message
4025 and silc_client_send_private_message functions. Affected file
4028 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Redefined the Private Message Payload to support private message
4031 keys and to support the new private message flags. Updated
4032 the protocol specs. Flags makes it possible to have for example
4033 CTCP style messages.
4035 * Added new type SilcPrivateMessagePayload and defined an API
4036 for it in the lib/silcclient/silcprivate.[ch].
4038 * Tested private message private keys successfully. Tested the
4039 private message key set, unset and list commands with the new
4042 * Redefined the Channel Message Payload to include the channel
4043 message flags (equal with private message flags) to support
4044 for example CTCP style messages.
4046 * Defined some of the message (for channel and private message)
4047 flags. Updated the protocol specs and added the flags to the
4048 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4050 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Added SilcKeyAgreementStatus type to the key agreement routines
4053 to indicate the current status and error if one occured.
4054 The status types are defined in the lib/silcclient/silcapi.h.
4056 * Added new local command KEY that is used to set and unset private
4057 keys for channels, set and unset private keys for private messages
4058 with remote clients and to send key agreement requests and
4059 negotiate the key agreement protocol with remote client. The
4060 key agreement is supported only to negotiate private message keys,
4061 it currently cannot be used to negotiate private keys for channels,
4062 as it is not convenient for that purpose.
4064 * Fixed a minor pending callback setting bug in the function
4065 silc_client_get_client_by_id_resolve, now the function works.
4066 Affected file lib/silcclient/idlist.c.
4068 * Added function silc_net_get_local_port to get local bound
4069 port by socket. Added to lib/silcutil/silcnet.[ch].
4071 * Added `sockets' and `sockets_count' fields to the SilcClient
4072 object. They hold the sockets of the listenning sockets in
4073 the client. Listenning sockets may be for example the key
4074 agreement server. Affected file lib/silcclient/client.[ch].
4075 Added functions the silc_client_add_socket and the
4076 silc_client_del_socket. They are exported to the application
4079 * Added ~./silc/clientkeys to support other client's public keys.
4081 * Renamed verify_server_key client operation to verify_public_key
4082 and added one argument to indicate the type of the connection
4083 (server, client etc.).
4085 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Added silc_server_connection_auth_request to handle the
4088 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4089 silcd/packet_receive.[ch].
4091 * Added silc_server_send_connection_auth_request into the
4092 silcd/packet_send.c to send the connection auth request packet.
4094 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4097 * Fixed the public key authentication in responder side in the
4098 server. The `auth_data' pointer includes the SilcPublicKey
4099 not the path to the public key. Affected file silcd/protocol.c.
4101 * Implemented the public key authentication in the initiator side
4102 in the server. Affected file silcd/protocol.c.
4104 * Removed the [RedirectClient] config section from the server
4105 configuration. Is not needed and I don't want to implement it.
4107 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Cleaned up the CMODE command in the server. It now works
4110 correctly and supports all the modes defined in the protocol.
4111 Affected file is silcd/command.c.
4113 * Added `hmac_name' field to the SilcChannelEntry in the server
4114 to hold the default HMAC of the channel. It can be set when
4115 creating the channel (with JOIN command). Affected files
4118 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4119 type to indicate the change of the current cipher and hmac
4120 on the channel. Client can safely ignore the <cipher> argument
4121 (if it chooses to do so) since the CHANNEL_KEY packet will
4122 force the channel key change anyway. The <hmac> argument is
4123 important since the client is responsible of setting the new
4124 HMAC and the hmac key into use.
4126 * Fixed the CMODE command in the client library as well.
4128 * Tested CMODE command in router environment successfully.
4130 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Show the version of the remote client (or server) when connecting
4133 to the server. It is logged to the log file. Affected file
4134 is silcd/protocol.c.
4136 * Fixed the KILLED notify handling in the client library. The
4137 client must be removed from all channels when receiving the
4140 Also, do not remove the client entry when giving the KILL
4141 command but when the KILLED notify is received.
4143 * Removed silc_idlist_find_client_by_nickname from the server.
4144 Not needed anymore. Affected files silcd/idlist.[ch].
4146 * Implemented the CHANNEL_CHANGE notify type handling to the
4147 server. Affected file silcd/server.c.
4151 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Added silc_server_send_notify_invite to send the INVITE
4154 notify between routers.
4156 * Implemented the INVITE command correctly to the server.
4158 * Implemented the INVITE notify type handling in the server.
4160 * Implemented the INVITE command to the client library and on the
4163 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Added function silc_server_get_client_resolve to find the
4166 client entry by ID from all ID lists and then resolve it
4167 (using WHOIS) if it cannot be found. Affected file is
4170 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Implemented the BAN command to the client library.
4174 * The JOIN command in the server now checks the invite list
4177 * Changed the silc_command_reply_payload_encode_va and the
4178 silc_command_payload_encode_va to support that if argument is
4179 NULL it ignores and checks the next argument. Affected file
4180 lib/silccore/silccommand.c.
4182 * Added silc_server_send_notify_ban to send the BAN notify
4183 type between routers.
4185 * Chaned the silc_notify_payload_encode to support that if
4186 argument is NULL it ignores and checks the next argument.
4187 Affected file lib/silccore/silcnotify.c.
4189 * Tested ban lists in router environment successfully.
4191 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4193 * Implemented BAN command to the server, in silcd/command.[ch].
4195 * Removed the BAN and INVITE_LIST modes from the CMODE command
4198 * Added function silc_string_match to regex match two strings.
4199 Affected files lib/silcutil/silcutil.[ch].
4201 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Redefined parts of the SilcChannelEntry in the server to support
4204 the new ban and invite lists.
4206 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Redefined the INVITE command. The same command can be used to
4209 invite individuals to the channel but also to manage the invite
4210 list of the channel (to add to and remove from the invite list).
4211 Updated the protocol specs.
4213 * Added new command SILC_COMMAND_BAN that can be used to manage
4214 the ban list of the channel. Updated the protocol specs.
4216 * Removed the channel modes: the SILC_CMODE_BAN and the
4217 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4218 in the CMODE command. The equivalent features are now available
4219 using INVITE and BAN commands. Updated the protocol specs.
4221 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4222 in the network about change in the current ban list. The notify
4223 type is not used by the client.
4225 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4226 support the invite lists.
4228 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * Added new function silc_string_regexify that converts string
4231 including wildcard characters into regex string that can
4232 be used by the GNU regex library. Added into the file
4233 lib/silcutil/silcutil.[ch].
4235 Added silc_string_regex_combine to combine to regex strings
4236 into one so that they can be used as one regex string by
4237 the GNU regex library. Added into the file
4238 lib/silcutil/silcutil.[ch].
4240 Added silc_string_regex_match to match two strings. It returns
4241 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4243 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Imported GNU regex to the soruce tree into lib/contrib.
4246 Fixed some compiler warning from the regex.c.
4248 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Fixed MOTD command in the server to work in router environment.
4252 * Fixed the MOTD command in the client library to support
4253 the server argument in the command.
4255 * Added `nickname_len' argument to the silc_idlist_add_client
4256 in the server, as the `nickname' argument may be binary data
4259 * Added silc_idlist_get_channels to return all channels from
4262 * Implemented LIST command to the server. Affected file is
4265 * Implemented the LIST command to the client library and on the
4268 * Added [<user count>] argument to the LIST command reply.
4269 With private channels the user count is not shown.
4271 * Updated TODO and README.
4273 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * The client entry's data.registered must be TRUE even with
4276 global client entry on global client list. The data.registered
4277 is used to check whether the client is anymore in the network,
4278 for example with WHOWAS command so it must be valid.
4280 * Fixed the WHOWAS command in the server. It now actually works
4281 in router environment. Added function into silcd/command_reply.c
4282 silc_server_command_reply_whowas_save.
4284 * Added silc_idlist_purge function to the silcd/idlist.c
4285 to periodically purge the ID Cache.
4287 * Fixed INFO command in the server. It works now in router
4288 environment. Added <server name> argument to the INFO command
4289 reply. Updated the protocol specs.
4291 * Fixed minor bug in silc_idcache_purge to not purge if the
4292 expire value is zero.
4294 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4295 they were buggy because of the WHOWAS information.
4297 * Fixed local command MSG to handle the async resolving of
4298 the remote client properly. It used to fail the first MSG.
4299 Affected file silc/local_command.c.
4301 * Added `data_len' field to SilcIDCache context.
4303 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Update TODO. Todo in commands in the server.
4307 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4310 used by routers as broadcast packet to inform other routers
4311 about the changed user mode.
4313 Implemented the notify handling in the server. Affected file is
4314 silcd/packet_receive.c. Added the function
4315 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4317 * Added new generic Channel Payload and deprecated the New Channel
4318 Payload. The New Channel Payload is now the generic Channel
4321 * Added new argument `mode' to the silc_server_send_new_channel
4322 as it is required in the Channel Payload now.
4324 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4325 and created a new and real SilChannelPayload to represent the
4326 new generic Channel Payload. Implemented the encode/decode
4327 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4329 * Added silc_server_get_client_channel_list to return the list
4330 of channels the client has joined for WHOIS command reply.
4331 Affected file silcd/server.[ch].
4333 * Implemented the channel list sending in the WHOIS command reply
4334 in server and in the client.
4336 Implemented the channel list displaying on the user interface
4337 as well. Affected file silc/client_ops.c.
4339 * Added silc_channel_payload_parse_list to parse list of Channel
4340 Payloads. It returns SilcDList list of SilcChannelPayloads.
4341 Client for example can use this function to parse the list of
4342 channels it receives in the WHOIS command reply. The caller
4343 must free the list by calling silc_channel_payload_list_free.
4344 Affected files lib/silccore/silcchannel.[ch].
4346 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4348 * Added one new argument <user mode> to the WHOIS command reply
4349 to return the mode of the user in SILC. Updated the protocol
4352 Implemented it to the server and client.
4354 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Fixed the mode printing on the user interface on joining.
4357 Affected file silc/client_ops.c.
4359 * Implemented the UMODE command and user modes in general to the
4360 client library and to the user interface.
4362 * Implemented the UMODE command to the server.
4364 * The server now sends UNKNOWN_COMMAND error status if client sends
4365 unknown command. Affected file silcd/command.c.
4367 * All server commands now handle the command identifier the right
4368 way when sending the command reply to the client. The client can
4369 use to identify the command replies with the identifier.
4371 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added silc_server_get_client_route to resolve the route to
4374 the client indicated by the client ID. Affected file is
4377 * Added silc_server_relay_packet as general function to relay
4378 packet to arbitrary destination. This deprecates functions
4379 like _send_private_message_key, _relay_notify etc. Affected
4380 file is silcd/packet_send.[ch].
4382 Removed silc_server_send_key_agreement,
4383 silc_server_send_private_message_key and
4384 silc_server_packet_relay_notify functions from the file
4385 silcd/packet_send.[ch].
4389 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4390 server. Affected file silcd/packet_receive.[ch].
4392 * Implemented the KILL command to the client. Implemented the
4393 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4394 Affected files lib/silcclient/command[_reply].c and
4395 lib/silcclient/client_notify.c. Implemented the KILL notify
4396 printing in the user inteface.
4398 * Fixed a lot silc_parse_nick memory leaks from the client
4399 library in the file lib/silcclient/command.c.
4401 * Changed the silc_server_send_notify_on_channels's `sender'
4402 argument from SilcSocketConnection to SilcClientEntry to
4403 check the sender as entry and not as connection object and not
4404 to send to the client provided as argument. The affected file
4405 is silcd/packet_send.[ch].
4407 * The notify packets that are destined directly to the client used
4408 to not to be processed by the server. Now changed that and the
4409 server processes all notify packets. After relaying the packet
4410 to the client the notify packet is processed in the server.
4412 * The silc_server_free_client_data now checks whether there is
4413 pending outgoing traffic for the client and purges the data to
4414 the network before removing the client entry.
4416 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4419 an client is killed from the SILC Network. Updated the protocol
4422 Added new function silc_server_send_notify_killed to the
4423 silcd/packet_send.[ch].
4425 * Added function silc_server_packet_relay_notify to relay notify
4426 packets that are destined directly to a client. In this case
4427 the server does not process the notify packets but merely relays
4428 it to the client. Affected file silcd/packet_send.[ch].
4430 Added also silc_server_packet_process_relay_notify to check
4431 whereto relay the notify. Affected file is
4432 silcd/packet_receive.[ch].
4434 * Implemented the KILL command to the server.
4438 * Added the backup schema desgined last fall to the protocol
4439 specs for everyone to see. The specification is in the
4440 *-spec-xx.txt draft and the packet type definitions for the
4441 backup routers is in *-pp-xx.txt draft. Thusly, added also
4442 new packet type SILC_PACKET_CELL_ROUTERS.
4444 * A big security problem in the implementation discovered. The
4445 signoff of an client did not cause new channel key generation
4446 which it of course should've done. The channel keys must be
4447 always re-generated when client leaves (or signoffs) the channel.
4448 The silc_server_remove_from_channels funtion now handles
4449 the channel key re-generation.
4451 * Added `sender' argument to the silc_server_send_notify_on_channels
4452 to not to send the client provided as argument. Affected file
4453 silcd/packet_send.[ch].
4455 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Implemented OPER and SILCOPER commands into the server and
4460 * Added silc_auth_verify and silc_auth_verify_data to verify
4461 the authentication directly from the authentication payload.
4462 It supports verifying both passphrase and public key based
4463 authentication. Affected file lib/silccore/silcauth.[ch].
4465 * Added `hash' field to the SilcIDListData structure. It is the
4466 hash negotiated in the SKE protocol. Affected file is
4469 * Slight redesigning of the SilcAuthPayload handling routines.
4470 Do not send SilcPKCS but SilcPublicKey as argument.
4472 * Implemented the public key authentication support to the
4473 serverconfig. The public key is loaded from the provided path
4474 and saved as authentication data to void * pointer. Thus,
4475 changed the unsigned char *auth_data to void *auth_data;
4477 * Fixed SHUTDOWN command to send the reply before the server
4478 is shutdown. :) Affected file silcd/command.c.
4480 * Fixed fatal bug in CONNECT command. The hostname was invalid
4481 memory and server crashed. Affected file silcd/command.c.
4483 * Fixed fatal bug in CLOSE command. The server_entry became
4484 invalid but was referenced later in the command. Affected file
4487 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4489 * Fixed fatal bug in failure packet handling. Server ignored
4490 the failure and thus crashed when it came.
4494 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4496 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4497 that the command may be executed only once in (about) 2 seconds.
4498 The old SILC_CF_LAG flag is same but allows command bursts up
4499 to five before limiting.
4501 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4502 server code. Various commands now includes the CF_LAG_STRICT
4503 flag to disallow any kind of miss-use of the command.
4505 * Fixed the silc_buffer_unformat to not to allocate any data
4506 if the length of the data is zero. It used to allocate the
4507 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4509 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Changed the format of AdminConnection configuration section
4512 in the server. Added username of the admin to the format.
4513 Affected files silcd/serverconfig.[ch].
4515 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4516 to return admin configuration data by host, username and/or
4519 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Implemented WHOWAS command to the server. Added the functions:
4523 silc_server_command_whowas_parse,
4524 silc_server_command_whowas_send_reply,
4525 silc_server_command_whowas_from_client and
4526 silc_server_command_whowas_from_server
4528 * Added <Client ID> argument to the WHOWAS command reply. Updated
4529 the protocol specs accordingly.
4531 * Implemented WHOWAS command and command_reply to the client
4534 Implemented the WHOWAS printing on the user interface.
4536 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Added new argument to the WHOWAS command reply, the real name.
4539 It is an optional argument. Updated the protocol specs.
4541 * Added SilcIDCacheDestructor callback that is registered when
4542 the SilcIDCache is allocated. The callback is called when
4543 an cache entry in the ID Cache expires, or is purged from the
4544 cache. Added into lib/silccore/idcache.[ch].
4546 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4547 to destruct the client entries when the cache entry expires.
4548 Other ID Cache's in server and in the client library ignores
4551 * If the ID Cache entry's `expire' field is zero then the entry
4552 never expires. Added boolean `expire' argument to the
4553 silc_idcache_add function in the lib/silccore/idcache.[ch].
4554 If it is TRUE the default expiry value is used.
4556 * Added silc_server_free_client_data_timeout that is registered
4557 when client disconnects. By default for 5 minutes we preserve
4558 the client entry for history - for WHOWAS command.
4560 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Added support to the server to enforce that commands are not
4563 executed more than once in 2 seconds. If server receives
4564 commands from client more frequently, timeout is registered
4565 to process the commands. Affected file silcd/command.c.
4566 Added new function silc_server_command_process_timeout.
4568 * Changed NICK_NOTIFY handling in client library to check that
4569 if the client's nickname was changed, so there is no need to
4570 resolve anything from the server.
4572 * Removed error printing from the WHOIS and IDENTIFY commands.
4573 If error occurs then it is ignored silently in the client library.
4574 The application, however, may map the received error to
4575 human readable error string. The application currently maps
4576 the NO_SUCH_NICKNAME error to string.
4578 * Made the command status message public to the application. Moved
4579 them from lib/silcclient/command_reply.c to
4580 lib/silcclient/command_reply.h. The application can map the
4581 received command status to the string with the
4582 silc_client_command_status_message function.
4584 * Added check to the server to check that client's ID is same
4585 as the Source ID in the packet the client sent. They must
4588 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added dist-bzip hook to the Makefile.am to make bzip2
4591 compressed distributions.
4593 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Server now enforces the maximum length for the nickname and
4596 the channel as protocol specification dictates. 128 bytes for
4597 nickname and 256 bytes for channel name.
4599 * Moved the WHOIS printing to the application. The client libary
4600 does not print out the WHOIS information anymore, the application
4601 must do it. Renamed silc_client_command_reply_whois_print to
4602 the silc_client_command_reply_whois_save.
4604 The client's idle time is also sent to the application now, and
4605 the idle is shown on screen.
4607 * Added silc_client_command_reply_identify_save to save the
4608 received IDENTIFY entries.
4610 * Do not check for channel private keys in message sending and
4611 reception if the channel does not have the PRIVKEY mode set.
4612 Affected file lib/silclient/client_channel.c.
4614 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4617 just surfaced after chaning the JOIN procedure.
4619 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Added silc_client_get_clients_by_list to get client entries
4622 from Client ID list, that is returned for example by JOIN
4623 and USERS command replies. The application should use this
4624 function for example when JOIN command reply is received to
4625 resolve the clients already on the channel (library does not
4626 do that anymore as USERS command reply is not used in the JOIN
4627 procedure anymore). Affected files lib/silcclient/silcapi.h and
4628 lib/silcclient/idlist.c.
4630 * JOIN command reply and USERS command reply returns now SilcBuffer
4631 pointers instead of unsigned char pointers when returning
4632 the client list and mode list.
4634 * Added <Client ID> argument to the JOIN command reply, mainly
4635 for the server to identify for which client the command was
4636 originally sent. Updated protocol specs accordingly.
4638 * Added SilcDlist private_key pointer to the SilcChannelEntry
4639 in the client to support the channel private keys. Affected
4640 file is lib/silcclient/idlist.h.
4642 * Added SilcChannelPrivateKey argument to the function
4643 silc_client_send_channel_message so that application can choose
4644 to use specific private ke if it wants to. If it is not provided,
4645 the normal channel key is used, unless private keys are set.
4646 In this case the first (key that was added first) is used
4647 as the encryption key.
4649 * Implemented the support for channel private key handling.
4650 Implemented the following functions:
4652 silc_client_add_channel_private_key,
4653 silc_client_del_channel_private_keys,
4654 silc_client_del_channel_private_key,
4655 silc_client_list_channel_private_keys and
4656 silc_client_free_channel_private_keys
4658 Affected file lib/silcclient/client_channel.c.
4660 * Added the support for the private keys in the channel message
4661 sending and encryption and in the message reception and
4662 decryption. Affected funtions are
4663 silc_client_send_channel_message and silc_client_channel_message.
4665 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Added SKE's key verify callback to the client library's
4668 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4670 * Removed the statement that server (or router) must send USERS
4671 command reply when joining to the channel so that the client
4672 knows who are on the channel. Instead, the client list and
4673 client's mode list is now sent in the JOIN command reply to the
4674 client who joined channel. This is better solution.
4676 * Added function silc_server_get_users_on_channel and function
4677 silc_server_save_users_on_channel to the silcd/server.[ch].
4679 * Removed function silc_server_command_send_users from the
4682 * Do not show topic on the client library anymore. The topic is
4683 sent in the command reply notify to the application and the
4684 application must show the topic now.
4686 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added client searching by nickname hash into the IDENTIFY and
4689 WHOIS commands in the server as they were clearly missing from
4690 them. Affected file is silcd/command.c.
4692 * Fixed a bug in private message receiving in the client library.
4693 The remote ID was freed and it wasn't supposed, now it is
4696 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Minor fix to the channel payload; allocate the data area, as it
4699 needs to be of specific length.
4701 * If the key agreement port is zero then the operating
4702 system will define the bound port. Affected files are
4703 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4705 * Added new function silc_channel_payload_decrypt into the file
4706 lib/silccore/silcchannel.[ch].
4708 * Moved the channel message etc, check from silc_packet_decrypt
4709 to applications. The library calls now a generic
4710 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4711 when the packet is either normal or special. This was done to
4712 allow more wide range of checking that was not allowed when
4713 the code was in library. Now applications can do virtually any
4714 checks to the packet and return to the library the decision how
4715 the packet should be processed. Affected files are
4716 lib/silccore/silcpacket.[ch].
4718 Added silc_server_packet_decrypt_check to the server and
4719 silc_client_packet_decrypt_check to the client library.
4721 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4722 to send with specified source and destination information.
4724 * Channel message delivery between routers was broken after the
4725 channel key distribution was fixed earlier. The channel key
4726 was used be to distributed to other routers as well which is not
4727 allowed by the protocol. Now this is fixed and channel keys
4728 really are cell specific and the channel message delivery between
4729 routers comply with the protocol specification.
4731 * Fixed various commands in server to check also the global list
4732 for the channel entry and not just the local list. The affected
4733 file silcd/command.c.
4735 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Added assert()s to buffer formatting and unformatting routines
4738 to assert (if --enable-debug) when error occurs. Affected
4739 file: lib/silcutil/silcbuffmt.c.
4741 * Changed to auto-reconnect to check whether the remote host is
4742 router and register the re-connect timeout if it is. It used
4743 to check that whether we are normal server, but router must do
4744 auto-reconnect with another router as well. Affected file
4747 * Removed the [<key len>] option from CMODE command as the cipher
4748 name decides the key length, nowadays. See the defined ciphers
4749 from the protocol specification.
4751 * Added [<hmac>] option to the CMODE command to define the HMAC
4752 for the channel. Added SILC_CMODE_HMAC channel mode.
4754 * Added [<hmac>] option for the JOIN command so that user can
4755 select which HMAC is used to compute the MACs of the channel
4758 * Added Hmac field to the Channel Message Payload. The integrity
4759 of plaintext channel messages are now protected by computing
4760 MAC of the message and attaching the MAC to the payload. The
4761 MAC is encrypted. Now, it is clear that this causes some
4762 overhead to the size of the packet but rationale for this is that
4763 now the receiver can verify whether the channel message decrypted
4764 correctly and also when private keys are set for the channel the
4765 receiver can decrypt the packet with several keys and check from
4766 the MAC which key decrypted the message correctly.
4768 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4769 lib/silccrypt/silccipher.[ch].
4771 * Added silc_hash_len to return the digest length into the
4772 lib/silcrypt/silchash.[ch].
4774 * Rewrote parts of Silc Channel Payload interface in the
4775 lib/silccore/silcchannel.[ch]. The encode function now also
4776 encrypts the packet and parse function decrypts it.
4778 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Fixed a minor formatting bug in the SKE's key material processing.
4781 It actually might have processed the keys wrong way resulting
4784 * Redefined the mandatory HMAC algorithms and added new algorithms.
4785 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4786 and hmac-md5 truncated to 96 bits. The mandatory is now
4787 hmac-sha1-96. Rest are optional (including the one that used
4788 to be mandatory). Rationale for this is that the truncated HMAC
4789 length is sufficient from security point of view and can actually
4790 make the attack against the HMAC harder. Also, the truncated
4791 HMAC causes less overhead to the packets. See the RFC2104 for
4794 * Added new [hmac] configuration section. The SKE used to use
4795 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4796 is of course wrong. The official names that must be proposed in
4797 the SKE are the ones defined in the protocol specification
4798 (hmac-sha1-96 for example). The user can configure any hmac
4799 using any hash function configured in the [hash] section. At
4800 least, the mandatory must be configured.
4802 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4804 * Added HMAC list to the SKE proposal list. It has now both
4805 hash algorithm list and HMAC list. This makes the protocol
4806 incompatible with previous versions. The SKE now seems to work
4807 the way it is supposed to work, for the first time actually.
4809 * Defined plain Hash algorithms to the protocol specification.
4812 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4814 * Implemented support for key agreement packets into the server.
4815 Added functions silc_server_key_agreement and
4816 silc_server_send_key_agreement. Other than these functions,
4817 server has nothing to do with this packet.
4819 * Added support for private message key packets into the server.
4820 Added functions silc_server_private_message_key and
4821 silc_server_send_private_message_key.
4825 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4826 called in the protocol's final callback instead in the END
4827 protocol state. This makes a little more sense and in the same
4828 time in client we can use the same protocol routines for normal
4829 key exchange and to key agreement packet handling as well.
4831 * Added to both client's and server's KE protocol context the
4832 SilcSKEKeyMaterial pointer to save the key material. We will
4833 bring the key material to the protocol's final callback by doing
4834 this. The final callback must free the key material.
4836 * Added SKE's packet_send callback into client's KE protocol
4837 context so that the caller can choose what packet sending function
4838 is used. This way we can use different packet sending when
4839 doing normal SKE when doing key agreement packet handling (in
4840 the key agreement packet handling we do not want to encrypt
4843 * Implemented the responder side of the key agreement routines
4844 in the client. The client can now bind to specified port and
4845 accept incoming key negotiation. The key material is passed
4846 to the application after the protocol is over.
4848 * Implemented the processing of incoming Key Agreement packet
4849 in the client. Added function silc_client_key_agreement to
4852 * Implemented the intiator side of the key agreement routines
4853 in the client. The client can now initiate key agreement with
4854 another remote client. The key material is passed to the
4855 application after the protocol is over.
4857 * Created client_keyagr.c to include all the key agreement
4860 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4861 SILC_TASK_CALLBACK except that it is not static.
4863 * Created client_notify.c and moved the Notify packet handling
4864 from the client.[ch] into that file.
4866 * Created client_prvmsg.c and moved all private message and
4867 private message key routines from the client.[ch] into that file.
4869 * Create client_channel.c and moved all channel message and
4870 channel private key routines from the client.[ch] into that file.
4872 * Changed silc_client_get_client_by_id_resolve to resolve with
4873 WHOIS command instead of IDENTIFY command, in the file
4874 lib/silclient/idlist.c.
4876 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Implemented the SKE's responder side to the Client library.
4880 * When FAILURE is received to the protocol do not trust it
4881 blindly. Register a timeout to wait whether the remote closes
4882 the connection as it should do it, only after that process the
4883 actual failure. This was changed to both client and server.
4885 * Added client_internal.h to include some of the structures
4886 there instead of client.h in lib/silcclient/.
4888 * Added function silc_task_unregister_by_callback to unregister
4889 timeouts by the callback function.
4891 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Some "Incomplete WHOIS info" errors has been appearing on the
4894 log files. Took away the entry->userinfo check from WHOIS
4895 reply sending. The entry->userinfo is now " " if client did not
4896 provide one. I thought this was fixed earlier but something
4897 is wrong still. Let's see if the error still appears.
4899 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Fixed a minor bug in the login when the channel key is
4902 re-generated in the server. It used to generate the key in
4903 wrong order and thus caused problems in the channel traffic.
4905 * Fixed a minor bug in channel key distsribution after
4906 KICK command. The key was not sent to the router even though
4909 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Added silc_ske_process_key_material_data as generic routine
4912 to process any key material as the SILC protocol dictates. The
4913 function is used by the actual SKE library but can be used by
4914 applications as well. This relates to the private message keys
4915 and the channel private keys since they must be processed the
4916 same way the normal SILC session keys. The protocol dictates
4917 this. Affected files: lib/silcske/silcske.[ch].
4919 Added also silc_ske_free_key_material to free the
4920 SilcSKEKeyMaterial structure.
4922 * Defined silc_cipher_set_key function to set the key for
4923 cipher without using the object's method function. The affected
4924 files: lib/silccrypt/silccipher.[ch].
4926 * Implemented silc silc_client_add_private_message_key,
4927 silc_client_add_private_message_key_ske,
4928 silc_client_del_private_message_key,
4929 silc_client_list_private_message_keys and
4930 silc_client_free_private_message_keys functions in the
4933 Added functions silc_client_send_private_message_key to send
4934 the Private Message Key payload and silc_client_private_message_key
4935 to handle incoming Private Message Key payload.
4937 * Added Cipher field to the Private Message Key payload to set
4938 the cipher to be used. If ignored, the default cipher defined
4939 in the SILC protocol (aes-256-cbc) is used.
4941 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Removed lib/silcclient/ops.h file.
4945 Redefined parts of the SILC Client Library API. Created new
4946 file silcapi.h that deprecates the ops.h file and defines the
4947 published Client Library API. Defined also private message key
4948 API and channel private key API into the file.
4950 This is the file that the application must include from the
4951 SILC Client Library. Other files need not be included by
4952 the application anymore.
4954 * Added new key_agreement client operation callback and also
4955 defined the Key Agreement library API for the application.
4957 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4960 is used by clients to request key negotiation between another
4961 client in the SILC network. If the negotiation is started it
4962 is performed using the SKE protocol. The result of the
4963 negotiation, the secret key material, can be used for example
4964 as private message key.
4966 Implemented the Key Agreement payload into the files
4967 lib/silccore/silauth.[ch].
4969 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Redefined ciphers for the SILC protocol. Added some new ciphers
4972 and defined the key lengths for the algorithms. Changed the
4973 code accordingly. The default key length is now 256 bits.
4975 * Fixed SKE key distribution function silc_ske_process_key_material
4976 when the key length is more than 128 bits. The default key
4977 length in SILC is now 256 bits.
4979 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4980 to indicate unsupported algorithm.
4982 * Renamed rijndael.c to aes.c and all functions as well.
4984 * Fixed a long standing channel key setting bug in client library.
4985 Weird that it has never surfaced before.
4987 * Fixed bug in channel deletion. If the entire channel is removed
4988 then it must also delete the references of the channel entry
4989 from the client's channel list as the client's channel entry and
4990 the channel's client entry share same memory.
4992 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Implemented CONNECT and SHUTDOWN commands in the client.
4996 * Implemented CLOSE command to the client.
4998 * Added the function silc_idlist_find_server_by_name into the
4999 files silcd/idlist.[ch].
5001 Added the function silc_idlist_find_server_by_conn into the
5002 files silcd/idlist.[ch].
5004 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * DIE command was renamed to SHUTDOWN. Updated the both code
5009 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5010 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5012 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5015 * Added function silc_server_create_connection function to create
5016 connection to remote router. My server implementation actually
5017 does not allow router to connect to normal server (it expects
5018 that normal server always initiates the connection to the router)
5019 so the CONNECT command is only good for connecting to another
5022 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5025 or some other client was kicked from the channel.
5027 Implemented the handling of the notify type to both client
5030 Implemented silc_server_send_notify_kicked to send the KICKED
5031 notify. It is used to send it to the server's primary router.
5033 * Implemented the KICK command into server and client.
5035 * Added `query' argument to the silc_idlist_get_client function
5036 to indicate whether to query the client from server or not if
5039 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5040 to indicate that the client is not channel founder.
5044 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Removed the rng context from SilcPacketContext structure and
5047 changed that the packet routine uses the Global RNG API.
5049 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Added support for quit message that client can "leave" on the
5052 channel when it quits the SILC. It is ditributed inside the
5053 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5055 Added silc_server_free_client_data that will take the
5056 signoff message as argument.
5058 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5060 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Updated parts of the protocol specification to keep it up
5065 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5068 payloads in one packet.
5070 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5071 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5072 use now the new List flag.
5074 * Also deprecated the following packet types: REPLACE_ID,
5075 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5077 * Added list support for Notify packet in server.
5079 * Added silc_server_send_notify_channel_change to send the
5080 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5081 the silc_server_send_replace_id.
5083 * Added silc_server_send_notify_nick_change to send the
5084 NICK_CHANGE notify type. Deprecates the function
5085 silc_server_send_replace_id.
5087 * Added silc_server_send_notify_join to send the JOIN notify type.
5088 Deprecates the function silc_server_send_new_channel_user.
5090 * Added silc_server_send_notify_leave to send LEAVE notify type.
5091 Deprecates the function silc_server_send_remove_channel_user.
5093 * Added silc_server_send_notify_cmode and
5094 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5095 types. Deprecates the silc_server_send_set_mode function.
5097 * Added SERVER_SIGNOFF notify type to indicate that server has
5098 quit. This means that all clients on the channel from that
5099 server will drop. This can be also used when netsplit happens.
5101 Deprecated REMOVE_ID packet type since it is not needed anymore
5104 Added silc_server_send_notify_server_signoff to send the
5105 SERVER_SIGNOFF notify type. Deprecates the function
5106 silc_server_send_remove_id.
5108 Added also silc_server_send_notify_signoff to send the
5109 SIGNOFF notify type.
5111 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5112 SILC protocol from this day on. Changed the protocol
5113 specification as well.
5115 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5116 notify type. It is used between routers to notify about
5117 topic changes on a channel.
5119 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5122 * Partly updated the protocol specification to comply with the
5123 changes now made. It is still though a bit outdated.
5125 * The JOIN notify type now takes one extra argument <Channel ID>.
5126 The packet used to be destined to the channel but now the
5127 JOIN type may be sent as list thus it is impossible to
5128 destine it to any specific channel. By adding this argument
5129 it is again possible.
5131 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Added CREDITS file. The CHANGES and CREDITS file will appear
5134 in the distribution as well.
5136 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5139 types in the server's silcd/packet_receive.c.
5141 * Implemented CMODE and CUMODE to work in router environment.
5143 * Fixed minor encoding and decoding buglet from the
5144 lib/silccore/silcmode.c.
5146 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5149 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5151 * Changed all SilcConfigServer* and silc_config_server* to
5152 SilcServerConfig* and silc_server_config*, respectively.
5155 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Associated the ID (client or server ID) to the Authentication
5158 Payload to avoid any possibility of forging. Updated the
5159 protocol specification and the code accordingly.
5161 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * The RSA key length is now save to the RsaKey context in the
5164 key generation process in lib/silccrypt/rsa.c. The key length
5165 is now used to figure out the maximum size of the block allowed
5166 to be encrypted/signed.
5168 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5169 is equivalent to the silc_mp_mp2bin but does not allocate any
5172 * Changed silc_mp_mp2bin API to take length argument. If it is
5173 non-zero then the buffer is allocated that large. If zero, then
5174 the size is approximated using silc_mp_sizeinbase, which however
5177 * Created Global RNG API which is global RNG that application can
5178 initialize. After initializing, any routine anywhere in the
5179 code (including library) can use RNG without allocating a new
5180 RNG object. This was done to allow this sort of use of the
5181 RNG in code that has no chance to allocate RNG object. All
5182 applications currently allocate this and many routines in the
5183 library use this. Affected file lib/silccrypt/silcrng.[ch].
5185 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5186 it to use the Global RNG API.
5188 * Defined Authentication Payload into protocol specification that
5189 is used during SILC session to authenticate entities. It is
5190 used for example by client to authenticate itself to the server
5191 to obtain server operator privileges.
5193 Implemented this payload into the lib/silccore/silcauth.[ch].
5194 Implemented also routines for public key based authentication
5195 as the new protocol specification dictates.
5197 Moved definitions of different authentication methods from
5198 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5200 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5201 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5202 silc_pkcs_verify_with_hash functions into the file
5203 lib/silccrypt/silcpkcs.[ch].
5205 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * The client entry's userinfo pointer must be always valid.
5208 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5209 will fail since it requires the userinfo. Now, the userinfo
5210 is allocated as "" if actual userinfo does not exist. Actually,
5211 it must exist and it is totally Ok to drop client connections
5212 that does not announce the userinfo. However, we will make
5213 this workaround for now.
5215 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5216 to return the remote port by socket.
5218 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5220 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5221 SILC_SERVER_PENDING_EXEC and added an new macro
5222 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5223 data or when error occurs while processing the pending command.
5225 Added new argument `destructor' into silc_server_command_pending
5226 and to the SilcServerCommandPending object. This destructor is
5227 now called after calling the pending callback or if error occurs
5228 immediately. If error occurs the actual pending callback won't
5229 be called at all - only the destructor. The destructor may be
5230 NULL if destructor is not needed.
5232 All this applies for client library code as well. Similar
5233 changes were made there as well for the pending commands.
5235 In the client, the application must now allocate the
5236 SilcClientCommandContext with the silc_client_command_alloc
5239 * Added reference counter to the SilcServerCommandContext. Added
5240 function silc_server_command_alloc and silc_server_command_dup
5243 Same type of functions added to the client library for the same
5246 * Removed the cmd_ident from IDListData away since it is now
5247 global for all connections. It is the command identifier used
5248 in command sending and with pending commands. The affected file
5251 * Added reference counter to the SilcSocketConnection objecet to
5252 indicate the usage count of the object. The object won't be
5253 freed untill the reference counter hits zero. Currently only
5254 server uses this, and client ignores it. The client must be
5255 set to use this too later. The affected files are
5256 lib/silccore/silcsockconn.[ch]. Added also the function
5257 silc_socket_dup to increase the reference counter.
5259 This was mainly added because it is possible that the socket
5260 is removed underneath of pending command or other async
5261 operation. Now it won't be free'd and proper DISCONNECTING
5262 flags, etc. can be set to avoid sending data to connection that
5263 is not valid anymore.
5265 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5266 the connection. After that it sets SILC_SET_DISCONNECTED.
5267 It is, however, possible that the socket data is not still freed.
5268 The silc_server_packet_process now checks that data is not
5269 read or written to connection that is DISCONNECTED. The socket
5270 get's freed when the reference counter hits zero.
5272 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Changed the client operation API: channel_message operation's
5275 `sender' is now the client entry of the sender, not the nickname
5276 and the `channel' is the channel entry, not the channel name.
5278 In the private_message operation the `sender' is now also the
5279 client entry of the sender not the nickname.
5281 Affected file is lib/silcclient/ops.h and all applications
5282 using the client operations.
5284 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Moved the calling of ops->connect() from connect_to_server_final
5287 into receive_new_id functin since that is the point when the
5288 client is actually allowed to send traffic to network. The
5289 affected file is lib/silcclient/client.c.
5291 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5294 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5295 (if needs broadcasting) instead of broadcasting the packets one
5296 by one which would make a burst in the network traffic.
5298 * Added `broadcast' argument to the functions in silcd/server.[ch]
5299 silc_server_create_new_channel[_with_id] to indicate whether
5300 to send New Channel packet to primary router.
5302 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Added new function into the silcd/server.[ch] files:
5305 silc_server_create_new_channel_with_id to create new channel with
5306 already existing Channel ID.
5308 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5309 lib/silccore/silcpacket.h. This packet is used t send list of
5310 Set Mode payloads inside one packet. Server uses this to set
5311 the modes for the channels and clients on those channels, that it
5312 announced to the router when it connected to it. The protocol
5313 specification has been updated accordingly.
5315 * The silc_server_new_channel did not handle the packet coming
5316 from normal server as it normally does not send that. However,
5317 when it announces its channels it does send it. Implemented
5318 the support for that.
5320 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5321 into the file lib/silccore/id.h.
5323 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Fixed memory leaks in the functions silc_idlist_del_client,
5326 silc_idlist_del_channel and silc_idlist_del_server in the file
5327 silcd/idlist.c. All of those leaked like a sieve.
5329 * Fixed some small memory leaks in the client's function
5330 silc_client_notify_by_server.
5332 * Added functions into silcd/server.c: silc_server_announce_clients,
5333 silc_server_announce_channels and silc_server_announce_server.
5334 These functions are used by normal and router server to announce
5335 to its primary router about clients, channels and servers (when
5336 router) that we own. This is done after we've connected to the
5339 These functions effectively implements the following packet types:
5340 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5341 and SILC_PACKET_NEW_ID_LIST.
5343 * Added new functions into the silcd/packet_receive.[ch]:
5344 silc_server_new_id_list, silc_server_new_channel_list and
5345 silc_server_new_channel_user_list to handle the incoming
5346 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5348 * Added support of changing Channel ID in the function
5349 silc_server_replace_id. If the server that announces a channel
5350 to the router already exists in the router (with same name but
5351 with different Channel ID), router is responsible to send
5352 Replace ID packet to the server and force the server to change
5353 the Channel ID to the one router has.
5355 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5356 client that the Channel ID has been changed by the router. The
5357 normal server sends this to the client. Client must start using
5358 the new Channel ID as the channel's ID.
5360 Implemented handling of this new type into lib/silcclient/client.c
5361 into the function silc_client_notify_by_server.
5363 * Added new function silc_idlist_replace_channel_id into the files
5364 silcd/idlist.[ch] to replace the Channel ID.
5366 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Call silc_server_command_identify_check always when processing
5369 the IDENTIFY command in silcd/command.c
5371 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5374 send keepalive packets. The packet can be sent by clients,
5375 servers and routers.
5377 Added function silc_socket_set_heartbeat into the file
5378 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5379 If not set, the heartbeat is not performed. The actual
5380 heartbeat is implemented in the low level socket connection
5381 library. However, application is responsible of actually
5384 Added silc_server_send_heartbeat to send the actual heartbeat
5385 packet into silcd/packet_send.[ch]. Server now performs
5386 keepalive with all connections.
5388 * Added silc_task_get_first function into lib/silcutil/silctask.c
5389 to return the timeout task with shortest timeout. There was a bug
5390 in task unregistration that caused problems. TODO has been
5391 updated to include that task system must be rewritten.
5393 * The client library will now resolve the client information when
5394 receiving JOIN notify from server for client that we know but
5395 have incomplete information.
5397 * Rewrote parts of silc_server_remove_from_channels and
5398 silc_server_remove_from_one_channel as they did not remove the
5399 channel in some circumstances even though they should've.
5401 * Encryption problem encountered in server:
5403 The LEAVE command used to send the Channel Key packet to the
5404 router immediately after generating it. However, the code
5405 had earlier sent Remove Channel user packet but not immediately,
5406 ie. it was put to queue. The order of packets in the router
5407 was that Channel Key packet was first and Remove Channel User
5408 packet was second, even though they were encrypted in the
5409 reverse order. For this reason, MAC check failed. Now, this
5410 is fixed by not sending the Channel Key packet immediately but
5411 putting it to queue. However, this is more fundamental problem:
5412 packets that are in queue should actually not be encrypted
5413 because packets that are sent immediately gets encrypted
5414 actually with wrong IV (and thus MAC check fails). So, packets
5415 that are in queue should be encrypted when they are sent to
5416 the wire and not when they put to the queue.
5418 However, the problem is that the current system has not been
5419 designed to work that way. Instead, the packet is encrypted
5420 as soon as possible and left to the queue. The queue is then
5421 just purged into wire. There won't be any fixes for this
5422 any time soon. So, the current semantic for packet sending
5425 o If you send packet to remote host and do not force the send
5426 (the packet will be in queue) then all subsequent packets to the
5427 same remote host must also be put to the queue. Only after the
5428 queue has been purged is it safe again to force the packet
5431 o If you send all packets immediately then it safe to send
5432 any of subsequent packets through the queue, however, after
5433 the first packet is put to queue then any subsequent packets
5434 must also be put to the queue.
5436 Follow these rules and everything works fine.
5438 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Added new function silc_server_remove_clients_by_server to
5441 remove all client entries from ID list when the server connection
5442 is lost. In this case it is also important to invalidate all
5443 client entires as they hold the invalid server entry. This
5444 fixes fatal bug when server has lost connection and will reconnect
5447 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Made some sanity checks to silc_server_daemonise like to check
5450 whether the requested user and group actually exists.
5452 * Added sanity check to SKE's silc_ske_responder_finish to check
5453 that the public and private key actually is valid.
5455 * Invalidate the client's nickname when receiving Replace ID
5456 packet and the Client ID is being replaced. This means that the
5457 server will query the nickname if someone needs it (client)
5460 * Sort the ID Cache in client library when the ID Cache data
5461 has changed (needs sorting).
5463 * Do not allow for SILC client to create several connections to
5464 several servers. The client does not support windows right now
5465 and generating multiple connections causes weird behaviour.
5467 Irssi-silc client does support windows and can handle several
5468 connections without problems, see: www.irssi.org and SILC plugin.
5470 * Fixed some places where client was added to the IDList. The
5471 rule of thumb is following (in order to get everything right):
5472 If the client is directly connected local client then the
5473 `connection' argument must be set and `router' argument must be
5474 NULL to silc_idlist_add_client function. If the client is not
5475 directly connected client then the `router' argument must
5476 bet set and the `connection' argument must be NULL to the
5477 silc_idlist_add_client function.
5479 * The funtion silc_server_packet_send_local_channel actually did
5480 not check whether the client was locally connected or not. It
5481 does that now. Fixed a bug related to LEAVE command.
5483 * Fixed Remove Channel User payload parsing bug in server's
5484 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5486 * The server's silc_server_save_channel_key now checks also the
5487 global ID list for the channel as it might not be in the local
5488 list. Fixed a bug related to LEAVE command.
5490 * Is this the end of the [<unknown>] buglet that has been lurking
5491 around for a long time? A little for loop fix in server's
5492 silc_server_command_whois_parse that is used by both IDENTIFY
5493 and WHOIS command. At least, this was a clear bug and a cause
5494 of one type of [<unknown>] buglet.
5496 * WHOIS and IDENTIFY commands call the function
5497 silc_server_command_[whois/identify]_check function even if
5498 we are not router server.
5500 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Added --with-gmp configuration option. If set the GMP
5503 is always compiled in the SILC source tree. If not set then
5504 it is checked whether the system has the GMP3 installed. If
5505 it has then the GMP won't be compiled (the system's headers
5506 and library is used), if it doesn't have it then the GMP is
5507 compiled in the SILC source tree.
5509 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Changed RSA private exponent generation to what PKCS #1
5512 suggests. We try to find the smallest possible d by doing
5513 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5514 not security fix but optimization.
5516 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Added new config entry [Identity] to fork the server and run
5519 it as specific user and group. A patch from Bostik.
5521 * Imported Dotconf configuration library into lib/dotconf.
5522 This will be used to create the SILC configuration files later.
5523 It will appear in the distsribution after this commit.
5525 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * A big code auditing weekend happening. Auditing code for
5528 obvious mistakes, bugs and errors. Also, removing any code
5531 Removed files for being obsolete:
5533 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5534 inline in the file lib/silcutil/silcbuffer.h)
5536 o lib/silcutil/silcbufutil.c (the header has inline versions)
5538 Changed code to fix possible error conditions:
5540 o The buffer formatting routines now check that the destination
5541 buffer really has enough space to add the data. This applies for
5542 both buffer formatting and unformatting
5543 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5544 unformatting was changed to accomodate following rules:
5545 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5546 sent to the function while XXX_*STRING will not allocate or copy
5547 the data into the buffer. Instead it sets the pointer from the
5548 buffer into the pointer sent as argument (XXX_*STRING used to
5549 require that the pointer must be allocated already). This change
5550 makes this whole thing a bit more consistent and more optimized
5551 (note that the data returned in the unformatting with XXX_*STRING
5552 must not be freed now). The routines return now -1 on error.
5554 o Tried to find all code that use buffer_format and buffer_unformat
5555 and added return value checking to prevent formatting and
5556 especially unformatting errors and possible subsequent fatal
5559 o Changed ske->x and ske->KEY to mallocated pointers in
5560 lib/silcske/silcske.h. Fixed possible data and memory leak.
5562 o Added return value checking to all *_parse* functions. Fixed
5563 many memory leaks as well.
5565 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5566 so that buffer overflows would not happen. All code now also
5567 checks the return value as it can fail.
5569 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Added reconnection support to server if the normal server looses
5572 its connection to the router (for example if router is rebooted).
5573 The server performs normal reconnection strategy implemented
5574 to the server. Affected file silcd/server.c.
5576 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Added new packet type SILC_PACKET_SET_MODE that is used to
5579 distribute the information about changed modes (for clients,
5580 channels and clients channel modes) to all routers in the
5581 network. Updated the protocol specification accordingly.
5583 Added functions into silcd/packet_send.c and
5584 silcd/packet_receive.c: silc_server_send_set_mode,
5585 silc_server_set_mode.
5587 Added new files silcmode.[ch] into lib/silccore that implements
5588 the encoding and decoding of Set Mode Payload. Added new type
5589 SilcSetModePayload. Moved the definitions of different modes
5590 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5592 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Oops, a little mistake in server's connection authentication
5595 protocol. The protocol is not ended with FAILURE but with
5596 SUCCESS if the authentication is Ok. :) Affected file is
5599 * Implemented NICK_CHANGE notify handling in server in the file
5600 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5601 the local clients on the channel. After the changing nickname
5602 in router environment snhould work and the [<unknown>] nickname
5603 should appear no more.
5605 The silc_server_replace_id function that receives the Replace ID
5606 payload now sends the NICK_CHANGE notify type also in the file
5607 silcd/packet_receive.c
5609 * Changed WHOIS and IDENTIFY command to support the maximum amount
5610 of arguments defined in protocol specs (3328 arguments). This
5611 fixed a bug that caused problems when there were more than three
5614 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Added extra parameter, command identifier, to the
5617 silc_client_send_command so that explicit command identifier
5620 Changed that ID list routines uses specific command identifier
5621 when sending WHOIS/IDENTIFY requests to the server so that they
5622 can be identified when the reply comes back.
5624 Affected files lib/silcclient/command.[ch],
5625 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5627 * Added `sender' argument to silc_server_packet_send_to_channel
5628 to indicaet the sender who originally sent the packet to us
5629 that we are now re-sending. Ignored if NULL. Affected file
5630 silcd/packet_send.[ch].
5632 * Added some server statistics support in silcd/server_internal.h
5633 SilcServerStatistics structure and around the server code. Also
5634 send some nice statistics information when client is connecting
5637 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Fixed channel ID decoding in server's JOIN command reply in
5640 silcd/command_reply.c
5642 * Fixed braodcasting of replace ID payload to not to send it if
5643 we are standalone server in silcd/packet_receive.c.
5645 * Fixed all channel message sending routines to not to send
5646 packets to clients that has router set, since they are routed
5647 separately in the same function earlier. Affects file
5648 silcd/packet_send.c and all channel packet sending functions.
5650 * In USERS reply, res_argv[i] are not allocated, the table
5651 is allocated. Thus changed that free the table, not its
5654 * In server's whois_check and identify_check if the client is
5655 locally connected do not send any WHOIS commands - they are not
5658 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Fixed some minor bugs in client when sending WHOIS command. The
5661 arguments was in wrong order.
5663 * Removed statis function add_to_channel from server in
5664 silcd/command.c that was previously used with the joining but
5667 * Tested USERS command in router environment successfully with two
5668 routers, two servers and two clients.
5670 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Reorganized the USERS command and command reply in client library
5673 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5674 When the command is given by user we register a pending command
5675 callback that will reprocess the command after the reply has been
5676 received from the server. When reprocessing the packet we then
5677 display the information. Thus, the USERS information is displayed
5678 now in the command callback instead of in the command reply
5679 callback. The processing of the command is same as previously
5680 when server has sent the command reply in the JOINing process.
5682 * Added to USERS command in silcd/command_reply.c to join the client,
5683 we didn't use to know about, to the channel after we've created
5684 a client entry for it. Also, for clienet we did know already still
5685 check whether it is on the channel or not and add it if not.
5687 * Removed silc_server_command_join_notify as the function and its
5690 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Changed the client's pending command handling to the same as the
5693 server's pending command handling. It is also now possible to
5694 execute command reply functions from other command reply
5695 function as the function callbacks for commands and command
5696 replies are one and same. The pending commands are not static
5697 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5698 in client connection context. Thus, pending commands are server
5699 connection specific as it is convenient.
5701 Changed the function silc_client_command_pending and
5702 silc_client_command_pending_del and added new function
5703 silc_client_command_pending_check. Removed the
5704 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5707 * Added cmd_ident, current command identifier, to the client
5708 connection context in lib/silcclient/client.h to keep track on
5709 command identifiers used in command sending. Client's command reply
5710 function handling now supports the mandatory command identifiers.
5712 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5713 funtions in client to fully support pending command callbacks.
5715 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5716 as one of the arguments to the application in the command reply
5719 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5720 before first releasing SILC but came back. Now it is removed again
5721 and should come back nomore. The FORWARDED flag was used only
5722 by the JOINing procedure by forwarding the command packet to router.
5723 Now, the JOINing procedure has been changed to more generic (due
5724 to various router environment issues) and FORWARDED is not needed
5725 anymore for anything. The protocol specification is yet to be
5728 Now, removed silc_server_packet_forward from server and the flag
5729 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5731 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Renamed NAMES command to USERS command. The NAMES was named that
5734 due to historical reasons. Now it is renamed. Also, rewrote
5735 parts of the USERS command. The nickname list is not sent anymore
5736 by the server. Only Client ID and mode lists are sent in the USERS
5737 command. Changed this also to the protocol specification.
5739 The client now resolves the names and stuff after it receives
5740 the USERS list from the server when joining to the channel.
5742 * WHOIS and IDENTIFY commands has been changed to support multiple
5743 Client ID's per command. One can now search for multiple users
5744 in the network by sending only one WHOIS or IDENTIFY command.
5745 Changed the code and the protocol specifications.
5747 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5748 uses silc_server_command_whois_parse to parse the request. */
5750 * If normal server, do not parse the WHOIS and IDENTIFY requests
5751 before sending it to the router. Saves some time.
5753 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Fixed JOIN command on client library. Wrong number of arguments
5756 used to crash the client.
5758 * Added silc_server_channel_has_global function to check whether
5759 channel has global users or not.
5761 * Added silc_server_channel_has_local function to check whether channel
5762 has locally connected clients on the channel.
5764 * The silc_server_remove_from_one_channel now checks whether the
5765 channel has global users or not after given client was removed from
5766 the channel. It also checks whether the channel has local clients
5767 on the channel anymore. If it does not have then the channel entry
5768 is removed as it is not needed anymore.
5770 * The silc_server_notify now checks on JOIN notify whether the joining
5771 client is one of locally connected or global. If it is global then
5772 the channel has now global users on the channel and that is marked
5773 to the channel entry. Also, it now saves the global client to
5774 global list who is joining and JOINs it to the channel. This is
5775 for normal server, that is.
5777 Changed silc_server_send_notify_on_channel,
5778 silc_server_packet_relay_to_channel and
5779 silc_server_packet_send_to_channel check if we are normal server
5780 and client has router set (ie. global client) do not send the
5781 message to that client, as it is already routed to our router.
5783 * Implemented LEAVE notify type handling in silc_server_notify
5786 * Tested LEAVE command in router environment successfully. Tested
5787 with two routers, two servers and two clients.
5791 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5793 * Implemented SIGNOFF notify type handling in silc_server_notify
5796 * silc_server_remove_id now removes the client entry from all channels
5797 it has joined and thusly sends SIGNOFF notify type.
5799 * Rewrote the NAMES list generation in server by removing two excess
5800 loops. The lists are created now inside one loop.
5802 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * silc_server_remove_channel_user checks now also global list
5805 for channel and client.
5807 * silc_server_new_channel_user checks now both local and global
5808 list for channel and client. Fixed a bug in client id decoding.
5809 Used to decode wrong buffer.
5811 * silc_server_channel_message checks now both local and global
5812 list for channel entry.
5814 * Tested channel joining (hence JOIN) in router environment
5815 successfully. Tested with two routers, two servers and two
5818 * Tested channel message sending in router environment successfully.
5820 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Added silc_server_save_channel_key into server.[ch] to save the
5823 received channel key in Channel Key payload processing. It is
5824 also used in JOIN command reply handling.
5826 Equivalent function silc_client_save_channel_key added into
5827 client.[ch] into client library.
5829 * Changed JOIN command reply to send information whether the channel
5830 was created or not (is existing already) and the channel key
5831 payload. Changed protocol specs accordingly.
5833 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5834 the request was sent by ID and not by nickname. Crashed on
5837 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5840 now correctly save the received data.
5842 * silc_server_free_sock_user_data now notifies routers in the
5843 network about entities leaving the network.
5845 At the same time implemented functions silc_server_remove_id
5846 and silc_server_send_remove_id to receive and send REMOVE_ID
5847 packets. The packet is used to notify routers in the network
5848 about leaving entities. The ID removed will become invalid in
5851 * Added function silc_idlist_del_server into server. Removes and
5852 free's server entry from ID list.
5854 * silc_server_private_message function now checks, if we are router,
5855 that the destination ID really is valid ID, naturally.
5857 * In router when NEW_ID packet is received (for new client) the
5858 hash of the Client ID is saved in the ID Cache but the
5859 client->nickname is set to NULL, instead of putting the hash
5862 IDENTIFY command now also checks that client->nickname must be
5863 valid. If it is not if will request the data from the server who
5864 owns the client. Added new function
5865 silc_server_command_identify_check.
5867 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5868 to set the command to already allocated Command Payload.
5870 * Tested private message sending in router environment with two
5871 routers, two servers and two clients. Fixed minor bugs and now
5874 * Fixed segfault from client's NAMES command. Used to crash if
5877 * Forwarded packets must not be routed even if it is not destined
5878 to the receiver. Changed server code comply with this.
5880 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Added `require_reverse_mapping' boolean value to ServerParams
5883 structure. If TRUE (not default) the server will require that
5884 the connecting host has fully qualified domain name.
5886 If the reverse mapping is not required and hostname could not be
5887 found the IP address is used as hostname.
5889 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Implemented version string checking to both client and server.
5892 The check is incomplete currently due to the abnormal version
5893 strings used in development version of SILC.
5895 * Changed all command functions in server to use the new
5898 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5900 * Changed char *data to unsigned char *data in ID Cache system to
5901 support binary data as ID Cache data. Changed code to support
5902 binary data in lib/silccore/idcache.c.
5904 * Renamed silc_server_packet_relay_command_reply to
5905 silc_server_command_reply as it is normal packet receiving
5906 function. Rewrote the function to accept command replys for
5907 servers and not only for clients.
5909 * Mark remote router always as registered server if we are connecting
5910 to it. Otherwise, commands sent by the router to us are ignored.
5912 * All ID List find routines now returns the ID Cache Entry pointer
5913 as well if requested.
5915 * WHOIS command works now in router environment, tested with two
5916 routers, two servers and two clients.
5918 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5919 in router environment (as it is almost equivalent to WHOIS) but
5920 hasn't been tested thoroughly. Added new functions:
5922 silc_server_command_identify_parse
5923 silc_server_command_identify_send_reply
5924 silc_server_command_identify_from_client
5925 silc_server_command_identify_from_server
5927 * Disabled route cache adding because adding two different ID's with
5928 same IP replaces the old cache entry thus giving wrong route.
5929 The entry->router->connection is always the fastest route anyway
5930 so route cache may not be needed. Of course, new routes maybe
5931 established after receiving the ID when the entry->router->connection
5932 might not be anymore the most optimal.
5934 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Add route cache for received ID for fast routing.
5938 * Added silc_server_packet_route to route received packet on router
5939 that is not destined to us.
5941 * Renamed silc_server_get_route to silc_server_route_get.
5943 * Added id_string and id_string_len fields into SilcServer to
5944 include encoded ServerID for fast comparing without excess
5945 encoding of the ID's.
5947 * Cleaned up WHOIS command on server side. Added following static
5950 silc_server_command_whois_parse
5951 silc_server_command_whois_check
5952 silc_server_command_whois_send_reply
5953 silc_server_command_whois_from_client
5954 silc_server_command_whois_from_server
5956 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5957 arguments in command replies. All command functions should be
5958 updated to use this macro.
5960 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Minor typo fixes on command reply handling on server.
5964 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Added silc_server_command_add_to_channel internal routine to add
5967 the client to the channel after router has created the channel and
5968 sent command reply to the server.
5970 * Added generic silc_server_send_command to send any command from
5973 * Use static buffer with ID rendering instead of duplicating data.
5975 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Fixed a channel user mode bug when joining to a channel server gave
5978 everybody channel founder rights, oops.
5980 * We mark ourselves as the router of the incoming server connection
5981 if we are router ourselves. This way we can check in some packet
5982 sending functions whether it is locally connected server. For
5983 incoming router connections we put NULL.
5985 * For router sending packets locally means now always sending the
5986 packet cell wide; to local clients and local servers. For normal
5987 server sending packet locally means sending it to only local
5990 * Fixed the JOIN command to really work in router environment. If the
5991 channel is created it is always created by the router. Router is
5992 also responsible of making the initial joining to the channel,
5993 sending JOIN notify to the sending server and distributing
5994 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5995 does not exist server doesn't do anything else but forward the
5996 command to the router which performs everything.
5998 * Added silc_server_send_channel_key function to send the Channel Key
6001 * Added silc_server_create_channel_key to create new channel key. The
6002 channel key is now re-generated everytime someone joins or leaves
6003 a channel, as protocol dictates. Note: channel->key_len is the
6006 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6009 packet_receive.[ch] to separate packet sending and receiving
6010 routines. The server.[ch] now includes everything else including
6011 actual packet processing (writing and reading data) and other
6014 Renamed silc_server_private_message_send_internal to
6015 silc_server_send_private_message. The routine is still though
6016 used only to relay private messages as server does not send
6017 private messages itself.
6019 Renamed silc_server_new_channel to silc_server_create_new_channel
6020 and added new function sicl_server_new_channel that handles the
6021 incoming New Channel packet. Added also new sending function
6022 silc_server_send_new_channel to send New Channel Payload.
6024 * Added new function silc_server_notify to process incoming notify
6025 packet to the server/router. Server may then relay the notify
6026 to clients if needed.
6028 * Added new function silc_server_new_channel_user to process incoming
6029 New Channel User packet. Router will redistribute the packet and
6030 send JOIN notify to its local clients and locally connected servers
6031 if needed. Normal server will send JOIN notify to its local client
6032 on same channel when received this packet. Added also corresponding
6033 sending function silc_server_send_new_channel_user to sent the
6036 * Added boolean route argument to send_notif_to_channel and
6037 packet_send_to_channel functions to attempt to route the packet
6038 if it is TRUE and send only locally if it is FALSE.
6040 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * silc_server_replace_id now broadcasts the received replace ID
6043 packet if it is not broadcast packet already. The router must
6044 broadcast to inform other routers about changed ID.
6046 * Added backpointer to server's router into SilcServer context in
6047 silcd/server_internal.h.
6049 * Fixed silc_server_packet_broadcast to send correct broadcast
6052 * The channel key is now distributed to the local client as soon
6053 as it is received from the router (in router environment) so that
6054 no other packet may be sent for the channel until client has
6057 * silc_server_remove_channel_user now broadcasts the received
6058 Remove Channel User packet if it is not broadcast packet already.
6059 The router must broadcast to inform other routers about removed
6062 * Added users field into SilcPacketContext that is a reference count
6063 of the context. One can increase the reference count by calling
6064 silc_packet_context_dup which is now changed to just increase the
6065 reference count instead of duplicating the data. The reference
6066 count is decresed by calling silc_packet_context_free that will
6067 free the data after the reference count hits zero.
6069 For now on the packet context and everything allocated into it
6070 (including the raw packet from network) must be freed by calling
6071 the new silc_packet_context_free function. Added also new function
6072 silc_packet_context_alloc that must be used now to allocate the
6073 context. This also means that if a routine is asynchronous from
6074 silc_[client/server]_packet_parse_type the packet context must
6075 be duplicated by calling silc_packet_context_dup. Otherwise it
6076 gets free'd after silc_[client/server]_packet_parse_type returns.
6077 Also, one must remember that if packet is duplicated then its
6078 reference count must be decresed by calling the free function as
6079 many times as it was duplicated.
6081 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6082 from both client and server.
6084 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Made joining to a channel working in router environment.
6088 * Cleaned up JOIN command on server side and create function
6089 silc_server_command_join_channel internal routine to make the
6092 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Changed silc_command_pending list to SilcDList. Also, added
6095 `ident' field to SilcServerCommandPending structure to identify
6096 the reply and to call correct callback.
6098 Added silc_server_command_pending_check function to replace the
6099 corresnponding macro. The silc_command_pending list is not
6102 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6103 to set identifier to previously allocated Command Payload. It
6104 is used to set identifier for command when resending Command
6107 * Added silc_command_payload_encode_payload to encode Command
6108 Payload buffer from SilcCommandPayload structure.
6110 * Added silc_argument_payload_encode_payload to encode Argument
6111 payload buffer from SilcArgumentPayload structure.
6113 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Changed WHOIS command to support router connection on server side.
6116 The whois request is always sent to router unless the server is
6117 standalone server. After server has received the reply from the
6118 router will it send the reply to the client.
6120 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6121 broadcast received broadcast packet. The function is used only
6122 by router. The broadcast packet is always sent to the router's
6125 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6126 render given ID to printable string, for log files for example.
6128 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Made basic router to router connections working. At least they
6131 can now connect to each other but nothing really works the way
6132 they are supposed - yet.
6134 * Added new initiator token to RouterConnection configuration
6135 file in silcd/serverconfig.[ch]. It is used to tell whether we
6136 are the initiator to the remote router or whether we'll expect
6137 the other end to connect.
6139 * Moved registering of listener task to silc_server_init, hence
6140 the server starts listenning as soon as it is run, even if it
6141 does not have connections to other routers. Let's see how well
6144 * Changed default connection retry timeouts for more suitable in
6147 * Removed cipher and such arguments from silc_idlist_add_client
6148 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6149 Added new function silc_idlist_add_data to add the keys and stuff
6152 * Added SilcIDListData structure and added it to SilcClientEntry
6153 and SilcServerEntry as their first field in the structure. This
6154 way we can explicitly cast the ID entries to the SilcIDListData
6155 structure and get common data for the entries. In past, we had
6156 to first check what type of connection it is and then cast it to
6157 correct ID entry type. Now, we can directly cast the opaque
6158 pointer to the SilcIDListData (no matter what ID entry it actually
6159 is) and get the data needed.
6161 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6164 in some circumstances even if threre were timeout tasks, though not
6165 IO tasks, but tasks anyway. Now fixed.
6167 * Defined SilcServerConnection structure to hold connection specific
6168 stuff about directly connected servers and routers. The definition
6169 is currently in silcd/server_internal.h. I thought about having
6170 a bit more important role fro this struct but for now it is used
6171 only when connecting to other server (or router actually).
6173 * Added connecting retry support in server when connecting to
6174 router(s). The retry feature implement exponential backoff
6175 algorithm. Also, added SilcServerParams structure to hold default
6176 parameters for server. For now, it include these retry settings
6177 and are hard coded. After server is moded to be as Silc Server
6178 Library this structure will be more important.
6180 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Changed client librarys channel->clients table to SilcList and
6183 changed code accordingly.
6185 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Changed client's channel table to SilcList and changed code
6188 accordingly. Also changed SilcChannelClientEntry to include back-
6189 pointer to the channel so that client entry can use that structure
6190 as list as well and we have fast cross-reference to the channel.
6191 This change dramatically decreased the complexity of channel
6192 handling with client entry and vice versa (removed one extra
6193 loop when searching for channel entry from many functions).
6195 * Changed server->sim from table to SilcDList and changed code
6198 * NAMES command can now be used from user interface. It will show
6199 the user list on the channel, neatly.
6201 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6202 Code now saves realname of the user if it becomes available.
6204 * Renamed configure.in to configure.in.pre and made ./prepare
6205 script to automatically add correct version string to
6206 configure.in which it creates from configure.in.pre.
6208 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * NAMES command reply now shows users mode with the nickname when
6213 * Moved silc_client_ch[u]mode[_char] functions from
6214 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6215 place sucks, they are utility functions and should be in some
6218 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6220 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6223 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6227 * Added TRQ (efficient deque and list library) into lib/trq. This is
6228 a very good list library that is currently used in the SILC. Defined
6229 SilcList API over the library because I didn't like the API very
6230 much. See lib/trq/silclist.h for the API and examples of how to
6231 use the API. Fixed various places in the code to use the new
6232 SilcList API. The SilcList is meant for lists that has a structure
6233 already defined as a list. It is not suitable to add just some
6234 context to the list (in TRQ, the context is the list actually).
6236 So, I defined SilcDList that can be used for the purpose where
6237 predefined list structure does not exit. This can be used as
6238 such list. Now some context just can be added to the SilcDList.
6239 Currently this list is not used in the SILC just yet, though there
6240 are a lot places where this can replace dynamically allocated
6241 tables and I will fix these places, later, to use SilcDList.
6242 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6243 and use TRQ internally).
6245 Also fixed some annoying warning messages that the original TRQ
6246 code generated. Also minor changes to TRQ's Makefile.in.
6248 * Added support for querying by Client ID to both WHOIS and
6249 IDENTIFY commands into server, as required by the protocol.
6251 * Removed method function pointers from SilcBuffer structure. They
6252 weren't used to anything and just increased the context size for
6253 no good reason. This change also made silc_buffer_alloc and
6254 silc_buffer_free functions inline functions.
6256 * Disabled command flooding detection support until it's fixed so
6257 that it accepts commands in but does not execute them more than once
6260 * Added silc_net_localhost(), to return local hostname, into
6261 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6262 that must be initialized before calling silc_client_init.
6264 * Added new function: silc_server_send_notify_on_channels to send
6265 notify messages to all channels client has joined. It is assured
6266 that the message is sent only once per client.
6268 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6269 lib/silcutil/silcutil.[ch] as silc_format function. The new
6270 function is generic and is used by server as well, not only by
6271 the logging routines.
6273 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6274 the provided version string was not acceptable. Added new function:
6275 silc_ske_check_version into lib/silcske/silcske.h. The function
6276 must be implemented by the application (client or server) and it
6277 does not reside in the SKE library. The function checks the version
6278 string remote end sent.
6280 * Added back pointers (to opaque context and to SilcSocketConnection)
6281 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6283 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6284 duplicate packet context structure.
6286 * Changed `notify' client operation to send same arguments as client
6287 receives from server except for ID's. ID's are mapped to correct
6288 ID entry and that is returned. Also, if channel entry is not sent
6289 by server but the notify is for channel the channel entry is sent
6290 to application (otherwise application doesn't know that it is for
6291 channel (library gets it from packet's Destination ID)).
6293 * Added silc_client_remove_from_channels into client library to
6294 remove a client from all channels it has joined to. Used when
6295 received SIGNOFF notify from server. Added also new function
6296 silc_client_replace_from_channels to replace old ID entry with
6297 new ID entry on all channels. Used when received NICK_CHANGE
6300 * Fixed ID Cache list handling in silc_idlist_get_client in
6301 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6302 to get (or query) client by ID.
6304 * Updated TODO list.
6306 * Added connection authentication status message defined by the
6307 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6308 support for these into the code in client and server side.
6310 * Added generic function silc_client_send_command to send any command
6311 with variable argument list. Application should use this function
6312 to send commands if the command functions provided by the library
6313 does not suite for the application's user interface needs.
6315 * Added new `failure' client operation. Application is notified about
6316 received failure packet if client is executing a protocol. In this
6317 case the protocol's execution has failed.
6319 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6320 is required by the protocol.
6322 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6323 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6326 * Added status flag to SilcSKE object to indicate realtime status
6327 of the SKE protocol.
6329 * Application receives now exactly same command reply arguments as
6330 the library receives from server. However, if ID is received the
6331 corresponding ID entry is returned to the application (eg. Client
6332 ID is mapped to correct SilcClientEntry entry and that is returned).
6333 Changed command_reply client operation due to this change.
6335 * Changed all ID's in commands and in command replys as ID Payloads.
6336 Change affected both client and server side codes.
6338 All ID's sent in SILC network (with execption of ID's in SILC
6339 Packet header) are sent in ID Payload to support variable length
6342 * Server now notifies nick changes and notifies all clients on
6343 the channels about the new nickname (about the new Client ID,
6346 * Implemented CMODE command to change channel modes. Supports all
6347 channel modes defined by the protocol specs except ban and invite
6348 lists. (Also, private channel key mode is supported but support for
6349 setting private channel key in client is missing, thus, this mode
6350 has no effect on client side (except that server requires that the
6351 client uses private channel key and normal channel traffic does not
6354 Also, invite mode works per se, but INVITE command does not work
6355 yet correctly, so you can set channel as invite only channel but
6356 inviting clients to the channel does not work (it is yet to be
6357 thought what's the best way to do it).
6359 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6360 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6361 Implemented CUMODE command to change user's mode on the channel.
6362 Supports all modes defined by the protocol specs.
6364 * Added NAMES command reply to return users modes on the channel.
6366 * Removed unnecessary and slow ciphers from lib/silccrypt.
6368 * Set SO_KEEPALIVE option to connection sockets by default.
6370 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6372 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6373 redefined the Notify Payload into protocol specs.
6375 * Added silc_id_payload_parse_id to get ID directly from raw
6378 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6381 accept searching by Client ID as well.
6383 * Added support for LEAVE and SIGNOFF notify types in client library.
6385 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6386 to parse ID Payload from raw data.
6388 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Added flags parameter into silc_ske_assemble_security_properties
6391 function in lib/silcske/silcske.[ch].
6393 * Changed notify client operation to fit better for notify messages
6394 sent by server. The notify payload received from server is now
6395 passed to the application (after parsing it to SilcNotifyPayload).
6396 It is application's responsibility to retrieve the arguments
6397 from the payload and show the message the way it wants. The message
6398 sent by server is implementation specific.
6400 * Changed public keys to comply with the protocol specification.
6401 Old public keys are not supported anymore and are not compatible.
6403 * Removed nickname from Channel Payload as the latest draft removed
6404 it. The client must resolve the nickname from the NAMES command
6405 reply received when it joined the channel.
6407 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6409 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Fixed some errors in protocol specification drafts.
6413 * Created lib/silccore/silcnotify.c to implement Notify Payload
6414 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6415 generic payloads described by protocol specifications. The file
6416 includes implementations for ID Payload and Argument Payload.
6418 * Changed Command Payload implementation to use the new Argument
6419 Payload. Changed command_xxxx_payload to command_payload_xxxx
6420 to comply with SILC coding conventions.
6422 * Added suppport for Argument Payload handling in Notify Payload
6423 implementation as protocol requires it. Added the new support
6424 into server and client lib as well.
6426 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Added support for multiple nicknames on same channel. [n] is
6429 added locally to the nickname if there are more than one same
6430 nicknames on the channel.
6432 * Server now sends all nicknames that matched WHOIS request.
6433 Client also shows the list received from server.
6435 * Added TOPIC command to client side. User can now set and show
6436 current topic on channel.
6438 * Added MOTD command to client and server. Also, server sends the
6439 motd when client connects to the server.
6441 * Changed version strings to comply ISO 8601.
6443 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Fixed protocol error handling in client library. It should now
6446 cope even if the SKE fails for some reason.
6448 * Made new protocol specification drafts for submitting to IETF.
6450 * Implemented TOPIC command to server in silcd/command.c.
6452 * Added two new notify types into lib/silccore/silcnotify.h:
6453 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6454 notify nickname change and topic setting/change on a channel.
6456 * API change of command_reply operation in client library. The
6457 application gets now the status type received from server as well.
6459 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6463 * Cras fixed and optimized the packet handling even further and
6464 it should work now. Minor change to the prototype of function
6465 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6467 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Added new function into lib/silcutil/silcschedule.[ch]:
6470 silc_schedule_with_fd to select() a specified fd. The function
6471 returns after timeout expires or data arrives or goes. The
6472 function is used by packet routines to wait that all data is
6473 received from network.
6475 * Fixed data reading from network in lib/silccore/silcpacket.c.
6476 The code now assures that all data is read from the fd and then
6477 continues packet processing. This was a bug fix since the code
6478 used to drop some data in some circumstances.
6480 * Added new function into lib/silcclient/client.[ch]:
6481 silc_client_start_key_exchange to start key exchange after
6482 connection has been established to server. The code internally
6483 now uses this funtion but its main purpose was to provide it
6484 for applications that perform their own connecting. After
6485 application has created a connection it merely calls this
6486 function to start the key exchange between client and server.
6487 The library takes care of everything else after that.
6489 Updated also lib/silcclient/README to explain the usage of
6492 * Do not send to application information that connection has
6493 been established. Application gets notified it by connect
6496 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Applied cras's patch to add silc_schedule_one function. The
6499 function runs scheduler once and returns.
6501 * Fixed the scheduler after cras messed it up. The timeout
6502 handling works now as it's supposed to work.
6504 * Added into lib/silccore/ silcnotify.h to include notify
6505 message types support. Changed silc_server_send_notify*
6506 functions, in server.[ch], to support those new notify types.
6507 Added the support for the notify types into client library,
6508 as well. Added new notify client operation into ops.h in
6511 * Changed silc_server_packet_send_to_channel to send normal
6512 packets instead of just channel message packets. The function
6513 is now used to send the notify packets to channels. It is not
6514 used to send channel message packets anymore, as server never
6517 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6518 va_arg()s as it seems to require it nowadays. I guess, if SILC
6519 is compiled with older va_arg() the new code should work anyway.
6521 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Splitted core library. Core library (lib/silccore) includes
6524 now only SILC protocol specific core (and common) components.
6525 Created new utility library (lib/silcutil) that includes more
6526 generic purpose stuff. The stuff for util library was taken
6527 from the old core library. This was minor and easy split.
6529 * Created SILC Client Library (lib/silcclient) that includes
6530 implementation of the SILC client without user interface. This
6531 was major move from silc/ directory. The code has been changed
6532 so that it is transparent towards the user interface. The
6533 silc/ directory includes now the same user interface as before
6534 and it uses the new client library. Read lib/silcclient/README.
6535 Basicly, the client library performs everything else related
6536 to SILC except user interface handling. Also, configuration
6537 files are considered to be part of user interface and library
6538 does not handle them.
6540 This change also changed a lot of structures, function naming etc.
6541 Most important change was that SilcClientWindow object was
6542 renamed to SilcClientConnection in the client library. Created
6543 also new file lib/silcclient/ops.h. Also added new files
6544 silc/local_command.[ch] and silc/client_ops.[ch].
6546 All these changes were made to make it easier for user interface
6547 designers to create what ever user interface for the SILC client
6550 It is also expected that the server will be moved to lib
6551 directory as well and SILC Server Library will be created;
6552 sometimes in the future.
6554 * Removed Local commands from lib/silccore/silccommand.h as
6555 they are application specific and new client library does not
6556 handle any of those anymore.
6558 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6559 old client implementation in silc/.
6561 * Added support for callback functions in SILC_LOG_* macros.
6562 Application can now set its own callbacks that will be called
6563 instead of using the default functions that will always print
6564 the debug messages to stderr (or stdout). Also, debugging can
6565 now be disabled by setting silc_debug to FALSE and re-enabled by
6566 setting it to TRUE. Note, that logging will still work even
6567 if debugging is disabled.
6569 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6570 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6571 silc_log_reset_debug_callbacks.
6573 * To enable debugging in silc client one must give now -d
6574 option on command line.
6576 * Changed silc_schedule_init to automatically allocate task queues
6577 if they are not allocated before calling it.
6579 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Added GMP 3.1 into math library.
6583 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6586 a channel in SILC network. The packet is used by servers and
6587 routers to notify other routers that user has left a channel.
6588 This little feature was missing until now. Added the feature
6589 to protocol specification as well.
6591 Added functions: silc_server_send_remove_channel_user and
6592 silc_server_remove_channel_user into server.[ch].
6594 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6595 lib/silccore/silcpacket.h. However, they are not implemented
6598 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Fixed joining to a channel and sending channel messages
6601 between server and router. The channel message sending should
6602 now work inside a cell.
6604 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Fixed the private message sending between server and router.
6607 The private message sending should now work inside a cell.
6609 * Added silc_server_replace_id into server.[ch] to replace
6610 existing ID in the SILC network.
6612 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6613 and silc_idlist_replace_server_id into idlist.[ch] in server.
6615 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Fixed the server to server connections. Server can again now
6618 connect to router. Router to router connections probably does
6621 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Added dynamic protocol registering support. Now protocols can
6624 registered and unregistered on the fly. Patch by cras.
6626 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added lib/contrib directory to hold routines that some platforms
6629 don't have but are needed by SILC.
6631 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6632 into lin/contrib to provide getopt() and getopt_long() for
6633 those who don't have it.
6635 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Added AWAY command to client. When away message is set and
6638 client receives a private message packet the client automatically
6639 replies to the sender with the away message.
6641 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6642 bug seemed to be the cause of recent problems when compiling
6645 * Added version detection support to SKE protocol specification
6646 and added the new changes to the SKE implementation as well.
6647 There were other minor changes in the SKE protocol as well.
6649 Many changes in lib/silcske/silcske.[ch] and in
6650 lib/silcske/payload.[ch].
6652 * Added ^U functionality, clear input line. Patch from cras.
6654 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Mainly small bugfixes on core library. Fixed some debugging
6657 logging and buffer overflow in silclog.c.
6659 * Updated config.sub and config.guess on the distribution tree.
6661 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Added command lagging support in server. Client may execute
6664 commands now only once in two seconds.
6666 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Optimized packet reception. MAC computation and checking is now
6669 also more optimized. A lot previously duplicated code is now
6670 used as generic by both client and server.
6672 * Fixed key pair generation in clientutil.c
6674 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added into lib/silccore/silcbufutil.[ch] new function;
6677 silc_buffer_realloc.
6679 * Moved generic packet sending/encryption functions to
6680 lib/silccore/silcpacket.[ch] from client and server. Some
6681 rewriting of the functions.
6683 * Moved all generic packet reception/decryption functions to
6684 lib/silccore/silcpacket.[ch] from client and server. The
6685 packet processing is now much cleaner in both client and server.
6686 These were major changes in both client and server.
6688 * Created many common functions in server to do packet sending.
6689 Previously code were duplicated a lot, this has been removed
6692 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Rewrote major parts of the ID cache system. Don't know
6695 whether it is better now or not but at least the API is more
6698 * Major rewrite on ID cache stuff on client because of the ID
6699 cache API changes. Added idlist.c to client.
6701 * Also major rewrite on ID cache stuff on server as well.
6702 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6703 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6704 in hand, instead they are all put into the ID cache system now.
6705 All server_idlist_* routines uses ID cache now instead of
6706 traversing its own lists (those lists does not exist anymore).
6707 SilcIDList though still exists. Also, SilcXXXEntry's are
6710 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Finally made the SKE implementation compliant to the protocol
6713 specification. All mp integers are now binary encoded as
6714 opposed being HEX encoded.
6716 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6719 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6720 functions: silc_[encode/decode]_pem. Also added function
6721 silc_encode_pem_file to PEM encode with newlines ('\n') for
6724 * SILC public keys are now encoded either PEM or binary. Same
6725 option is for private keys as well. By default private keys
6726 are binary encoded and public keys PEM encoded. Silly HEX
6727 encoding were removed.
6729 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6730 function to create fingerprints.
6732 * Fixed a bug in SHA1; does not change the original data anymore.
6734 * Partly implemented INFO command on client and server side.
6735 Fixed CLEAR command. Changes to SERVER command; show current
6736 server(s) when giving command without arguments. Added
6737 VERSION command to client.
6739 * Added check to server that unregistered connections cannot
6740 execute commands (unless it is specificly allowed).
6742 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6744 * Fixed screen refresh.
6746 * Fixed channel joining bug from client. On some circumstances
6747 client tried to join to a channel it had already joined.
6749 * Added public key verification process into client's protocol.c.
6750 The client now verifies the public key from user and saves
6751 it into ~./silc/serverkeys/ directory.
6753 Added into: clientutil.[ch]: silc_client_verify_server_key.
6755 * Changed SKE protocol's silc_ske_initiator_finish function
6756 to accept callback function that verifies the received public
6757 key. Removed old silc_ske_verify_public_key function.
6759 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6761 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6762 silc_pkcs_private_key[_data]_set.
6764 * Made the password and public authentication more cleaner in
6765 server's protocol.c.
6767 * Removed historic and obsolete protocol `channel_auth' from
6768 both client and server.
6770 * Removed wrong way of sending command status messages from
6771 server to client in server's command.c. The old way violated
6772 protocol specification.
6774 Changes to silccore/silccommand.[ch]: removed
6775 silc_command_encode_status_payload -> not needed anymore,
6776 changed silc_command_encode_payload_va to accept extra
6777 argument on variable argument list. The argument type must
6778 now be provided to the function. Also, added new function:
6779 silc_command_encode_reply_payload_va which is same as
6780 normal command_encode_payload_va except command status type
6781 is provided as extra argument.
6783 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Added ~./silc directory handling. The directory includes the
6786 public and private keys for the client.
6788 Added silc_client_check_silc_dir, silc_client_create_identifier
6789 and silc_client_load_keys.
6791 * Implemented SILC protocol compliant public key. Added public
6792 and private key saving to and loading from files.
6794 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6795 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6796 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6797 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6798 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6800 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6801 silc_pkcs_load_[public/private]_key.
6803 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Added silc_server_get_route (route.[ch]) to get connection
6806 data for the fastest route for given ID.
6808 * Implemented INVITE command on client and server. The command
6809 were re-defined in the SILC Protocol Specification and the
6810 implementation now complies with the specification.
6812 * Implemented PING command on client and server.
6814 * Implemented NAMES command on client and server. The server side
6815 supports currently only normal server not router server yet.
6816 Some changes to NAMES definition in SILC protocol specification.
6818 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Implemented LEAVE command on client and server.
6822 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6823 again. This change was made to the protocol as well. Server
6824 should not violate the protocol specification anymore.
6826 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6829 was tested. SOCKS4 was not but should work anyway.
