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

582 * ROBOdoc documented the lib/silcske/groups.h file and a
583 bit changed the interface for better.
585 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
587 * Update the client entry context in the ID cache after
588 nick change. Affected file lib/silcclient/command.c.
589 Fixes the CUMODE command when regaining founder privileges,
590 and a little WHOIS problem.
592 * Fixed silc_net_gethostbyname to correctly call the
593 inet_ntop. Affected file lib/silcutil/silcnet.c.
595 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
597 * Added IPv6 support checking to the configure.in.pre, added
598 also --enable-ipv6 option to override the check. Affected
599 file configure.in.pre.

632 UI displays it. Affected files lib/silcclient/client_notify.c
633 and irssi/src/silc/core/silc-channels.c, module-formats.c.
635 * Made all payload parsing function prototypes consistent.
636 They all take now const unsigned char * and uint32 pair as
637 the payload data instead of SilcBuffer. Changes all around
638 the source tree. Other unsigned char* -> const unsigned char*
639 changes around the tree as well.
641 * Optimized SFTP client and server packet sending not to
642 allocate new buffer for each packet but to recycle the
643 first allocated buffer. Affected files are
644 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
646 * Optimized the SFTP client to use SilcList instead of
647 SilcDList for requests, because it is faster. Affected file
648 is lib/silcsftp/sftp_client.c.
650 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
651 into lib/silccore/silcid.[ch].

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

757 the dynamic list. Fixes a crash. Affected file is
758 lib/silccore/silcidcache.c.
760 * Fixed the LIST command reply to really call LIST command's
761 pending callbacks. Affected file silcd/command_reply.c.
763 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Update conn->local_entry->nickname after giving NICK
766 command. Affected file lib/silcclient/command.c.
768 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
770 * Added the [pid] option to the silcd configuration file

782 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
784 * Use ++server->cmd_ident when sending commands in server,
785 instead of random number. Affected file silcd/command.c.
787 * Fixed GETKEY command reply to call actually GETKEY pending
788 command callbacks. Affected file silcd/command_reply.c.
790 * A bit stricter check for nicknames. Check for same nickname
791 in NICK command also. Affected file silcd/command.c.
793 * Do not call INFO command everytime client ID changes, only
794 during first connecting. Affected file lib/silcclient/client.c.
796 * Set the new nickname only after successful command reply for
797 NICK command is returned by server. Affected file
798 lib/silcclient/command.c.
800 * Remove nicknames from nicklist during server_signoff notify.
801 Should fix /NAMES bit more. The affected file is
802 irssi/src/silc/core/silc-channels.c.
804 * Added `fingerprint' field to the SilcIDListData in the
805 silcd/idlist.h to hold the fingerprint of the client's
808 Send the fingerprint of the client's public key in WHOIS
811 Affected files silcd/command.c, and silcd/idlist.[ch].
813 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
814 create fingerprint from given data.
816 * Show the fingerprint of the client's public key in WHOIS.
817 Affected files irssi/src/module-formats.[ch] and
818 irssi/src/silc/core/client_ops.c.
820 * Format the multiple same nicknames also during JOIN and
821 NICK_CHANGE notifys. Affected file is
822 lib/silcclient/client_notify.c.
824 * Do not print error on screen for invalid private message
825 payload since it can come if someone is sending private
826 messages with wrong key. Affected file
827 lib/silccore/silcprivate.c.
829 * Fixed multiple concurrent /PING crash. Affected file
830 lib/silcclient/command.c.
832 * Changed the wrong ID encoding. All IP addresses must be
833 in MSB first order in encoded format. They were encoded
834 wrong and was in LSB format. Affected files are
835 silcd/serverid.c, lib/silcutil/silcutil.c.
837 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
839 * Call the `connect' client operation through the scheduler
840 in case of error. Affected file lib/silcclient/client.c.
842 * Call the `failure' client operation even if the error
843 occurred locally during a protocol. Affected file is
844 lib/silcclient/protocol.c.
846 * Added support of sending LIST command to router from normal
847 server. This way normal server can get list of all channels
848 in the network too. Fixed the channel list sending in the
849 server too. Affected files are silcd/command.c, and
850 silcd/command_reply.[ch].
852 * Added silc_server_update_channels_by_server and
853 silc_server_remove_channels_by_server. They are used during
854 disconnection of primary router and in backup router protocol.
855 Affected file silcd/server_util.[ch], silcd/server.c and
856 silcd/server_backup.c.
858 * Fixed channel adding to global list in IDENTIFY command
859 reply in server. Affected file silcd/command_reply.c.
861 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
863 * If the incoming packet type is REKEY or REKEY_DONE process
864 that packet always synchronously. Fixes yet another MAC
865 failed error on slow (dialup) connections. Affected file
866 lib/silcclient/client.c and silcd/server.c.
868 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Call check_version SKE callback for initiator too. Affected
871 file lib/silcske/silcske.c.
873 * Implemented fix for security hole found in the SKE that was
874 fixed in the specification few days back; the initiator's
875 public key is now added to the HASH value computation.
876 Added backwards support for the old way of doing it too, for
877 old clients and old servers. Affected file is
878 lib/silcske/silcske.c.
880 * Enabled mutual authentication by default in SKE. If initiator
881 is not providing mutual authentication the responder will
882 force it. This will provide the proof of posession of the
883 private key for responder. The affected files are
884 lib/silcclient/protocol.c and silcd/protocol.c.
886 * Do not cache anymore the server's public key during SKE.
887 We do mutual authentication so the proof of posession of
888 private key is done, and if the server is authenticated in
889 conn auth protocol with public key we must have the public
890 key already. Affected file silcd/protocol.c.
892 * Added new global debug variable: silc_debug_hexdump. If
893 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
894 file lib/silcutil/silclog.[ch].
896 * Fixed compilation warning due to char * -> const char *.
897 Affected files lib/silcutil/silcnet.h, and
898 lib/silccore/silcauth.[ch].
900 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
902 * Fixed CMODE command when new channel key was created. If
903 the creation failed the old key was removed. Next time giving
904 same command would crash the server since the old key was
905 freed already. Affected file silcd/command.c.
907 * Fixed the silc_server_announce_get_channels to not crash
908 on reconnect. Affected file silcd/server.c.
910 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Added silc_log_set_debug_string function to set a regex
913 string to match for debug output. Only the function names,
914 or filenames matching the given debug string is actually
915 printed. This way it is possible to filter out those debug
916 strings that user is not interested in.
918 Fixed a bug in silc_string_regexify.
920 Affected files lib/silcutil/silclog.[ch], and
921 lib/silcutil/unix/silcunixutil.c.
923 * Changed the -d options in both server and Irssi SILC client
924 to take the debug string as argument. Affected files
925 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
927 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
929 * Added silc_hash_babbleprint to create a Bubble Babble
930 Encoded fingerprint. The encoding is developed by Antti
931 Huima (draft-huima-babble-01.txt), and it creates human
932 readable strings out of binary data. Affected file
933 lib/silccrypt/silchash.[ch].
935 * Print the babble print now in addition of fingerprint as well
936 in Irssi SILC client. Affected files are
937 irssi/src/fe-common/silc/module-formats.[ch],
938 irssi/src/fe-common/silc/core/client_ops.c.
940 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Fixed a security problem found in SKE. The initiator's
943 public key too is now added to the HASH hash value creation
944 which is signed by the responder to create the SIGN value.
945 This will prevent anyone in the middle to lie to the responder
946 about the initiator's public key. If this is done now, the
947 man in the middle will get caught. Updated the protocol
950 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Better installation directory handling. Configure module
953 paths and other paths automatically to example_silc* files
954 in doc/. A patch by toma.
956 * Fixed compiler warning from MPI library, and from SILC RNG.
959 * Added SILC_SERVER_PID_FILE to define the pid file for server.
960 It can be configured with ./configure. A patch by toma.
962 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Find correct make to use in prepare-clean. A patch by
965 toma. Affected file prepare-clean.
967 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
969 * Added irssi variables use_auto_addr, auto_bind_ip,
970 auto_bind_port and auto_public_ip.
972 * Changed the interface for silc_client_send_key_agreement
973 in lib/silcclient/silcapi.h
977 irssi/src/silc/core/silc-core.c
979 lib/silcclient/silcapi.h
980 irssi/src/silc/core/silc-channels.c
981 lib/silcclient/client_keyagr.c
984 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
986 * Added silc_pkcs_public_key_compare to compare two
987 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
989 * Check that the client who set the founder mode on the
990 channel is the same client that is giving the founder
991 mode to itself. It is done by comparing the saved public
992 key (it is saved even in the authentication is passphrase).
993 Affected file silcd/command.c.
995 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
997 * Do not process packet for disconnected socket connection.
998 Affected file lib/silccore/silcpacket.c.
1000 * Process the DISCONNECT packet through scheduler in the
1001 client library. Affected file lib/silcclient/client.c.
1003 * Fixed the silc_client_packet_parse to not to increase
1004 the packet sequence number if the conn->sock and the
1005 current socket connection is not same. This can happen
1006 for example during key agreement when the conn includes
1007 multiple socket connections (listeners). Affected file
1008 lib/silcclient/client.c.
1010 * The sender of the file transfer request now provides also
1011 the pointer (listener) for the key exchange protocol. If
1012 the listener cannot be created then it sends empty key
1013 agreement and lets the receiver provide the listener.
1015 Added `local_ip' and `local_port' arguments to the
1016 silc_client_file_send. If they are provided they are used,
1017 if not then it will attempt to find local IP address, if
1018 not found or bind fails then the remote client will provide
1021 Affected files are lib/silcclient/client_ftp.c and
1022 lib/silcclient/silcapi.h.
1024 * Extended the FILE SEND command to support defining the
1025 local IP and port for key exchange listener. They are
1026 optional. Affected file irssi/src/silc/core/silc-servers.c.
1028 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Defined to WHOIS command reply the sending of fingerprint
1031 of the client's public key (if the proof of posession of the
1032 corresponding private key is verified by the server).
1033 Updated to the protocol specification.
1035 * Added support of receiving the client's public key's
1036 fingerprint in command reply in client library. Affected
1037 file is lib/silcclient/command_reply.c, and
1038 lib/silcclient/idlist.[ch].
1040 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Do not send over 128 chars long nickname to the server
1043 in NICK command. Affected file lib/silcclient/command.c.
1045 * Do not send over 256 chars long channel names to the server
1046 in JOIN command. Affected file lib/silcclient/command.c.
1048 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1050 * Assure that silc_server_close_connection cannot be called
1051 twice for same socket context. Affected file is
1054 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Send error message to application if opening file for
1057 writing during file transfer fails. Affected file is
1058 lib/silcclient/client_ftp.c.
1060 Remove all file transfer sessions for a client that we're
1061 removing from ID cache.
1063 Affected file is lib/silcclient/client_ftp.c.
1065 * Fixed silc_net_addr2bin to return correct address. Affected
1066 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1068 * Fixed file transfer session removing on signoff notify.
1069 Affected file irssi/src/silc/core/silc-servers.c.
1071 * Added the SilcClientFileError to be returned in the monitor
1072 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1073 Affected file lib/silcclient/silcapi.h.
1075 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Fixed a crash in silc_client_ftp_free_sessions and
1078 silc_client_ftp_session_free_client. Affected file
1079 lib/silcclient/client_ftp.c.
1081 * Added `disabled' field in the SilcChannelEntry in the server
1082 to indicate if the server entry is disabled. Affected file
1083 silcd/idlist.h, silcd/command[_reply].c.
1085 * SILC server adds now /var/run/silcd.pid everytime it is
1086 started. Affected file silcd/silcd.c.
1088 * Added silc_server_packet_send_clients to send a packet to
1089 the provided table of client entries. Affected file
1090 silcd/packet_send.[ch].
1092 * Fixed a crash in client resolving in client_prvmsg.c in
1093 client library. Affected file lib/silcclient/client_prvmsg.c.
1095 * Do not actually remove the client directly from ID cache
1096 during SERVER_SIGNOFF, but invalidate it. This way we
1097 preserve the WHOWAS info for the client. Affected file
1098 silcd/server_util.c.
1100 * Fixed SERVER_SIGNOFF notify handling in the server. The
1101 server is now able to process incoming SERVER_SIGNOFF notify
1102 for a server that it doesn't even know about. It will remove
1103 the clients provided in the notify. Affected file
1104 silcd/packet_receive.c.
1106 * Check for partial packet in data queue after every packet that
1107 was found from the queue. Return and wait for more data if
1108 there is partial data in queue. Affected file is
1109 lib/silccore/silcpacket.c.
1111 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1117 lib/silcclient/client_ftp.c.
1119 * Check that newsize in silc_buffer_realloc is larger than
1120 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1122 * Added better monitor of file transfers. It now monitors
1123 key agreement protocol during the file transfer too. Added
1124 error reporting too. Affected files
1125 irssi/src/silc/core/silc-servers.c,
1126 irssi/src/fe-common/silc/module-formats.[ch].
1128 * Wrote a help file for FILE command.
1130 * Added silc_rng_global_get_byte_fast to get not-so-secure
1131 random data as fast as possible. Random data is read from
1132 /dev/urandom if available and from the SILC RNG if not
1133 available. It is used in padding generation. Affected file
1134 lib/silccrypt/silcrng.[ch].
1136 * All packets in client library are now processed synchronously.
1137 Optimized packet processing a lot. Affected file
1138 lib/silcclient/client.c.

1141 now in server, to optimize packet processing. Affected file
1144 * Include files are installed now only in Toolkit distribution
1145 if make install is given. Affected files: all Makefile.am's.
1147 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1149 * Assure that silc_client_notify_by_server_resolve does not
1150 resolve the client information multiple times. If it cannot
1151 be found by the first it cannot be found at all. Affected
1152 file lib/silcclient/client_notify.c.
1154 * Fixed WHOWAS command reply calling. Affected file
1155 lib/silcclient/command_reply.c.
1157 * Removed all references to silc_idlist_get_client from the
1158 Irssi SILC client since that call is internal call used by
1159 the library. The Irssi SILC client will use now client
1160 retrieval functions found in silcapi.h.
1162 * Fixed a bug in resolving nickname info before sending
1163 private message. It used freed memory. Affected file
1164 irssi/src/silc/core/silc-servers.c.
1166 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Assure my_channels statistics cannot go negative in server.
1169 Affected files silcd/server.c, silcd/server_util.c.
1171 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1185 * Added silc_net_localip to return local host's IP address.
1186 Affected file lib/silcutil/silcnet.[ch].
1188 * If key exchange or rekey protocol is active for a connection
1189 parse all packets syncronously since there might be packets
1190 in packet queue that we are not able to process without first
1191 processing packets before them. Affected file silcd/server,
1192 lib/silcclient/client.c.
1194 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1195 whether library should continue processing the packet.
1196 Affected file lib/silccore/silcpacket.h.

1231 * Resolve the client info when received private message or
1232 channel message for a client which nickname we don't know.
1233 Affected files lib/silcclient/client_prvmsg.c and
1234 lib/silcclient/client_channel.c.
1236 * Do not crash in /KEY if client is not connected. Affected
1237 file irssi/src/silc/core/silc-channels.c.
1239 * Added SilcClientStatus field to the SilcClientEntry in the

1242 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1243 is incomplete and is being resolved, it won't be resolved
1246 Make sure also that USERS command reply does not resolve
1247 twice information. Affected file is
1248 lib/silcclient/command_reply.c.
1250 Make sure that silc_client_get_clients_by_list does not
1251 resolve twice same information.
1253 * Check for valid client->id in the silc_server_free_client_data.
1254 Affected file silcd/server.c.
1256 * Fixed /GETKEY nick@server not to crash if the server entry
1257 is not found. Affected file lib/silcclient/command.c.
1259 * Fixed the silc_server_check_cmode_rights to check the
1260 requested modes correctly. Affected file silcd/command.c.

1265 Affected file silcd/command.c.
1267 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Call the silc_server_udpate_servers_by_server in the
1270 primary router that comes back online in the backup resuming
1271 protocol. Otherwise it routes packets wrong. Affected file
1272 silcd/server_util.[ch], silcd/server_backup.c.
1274 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1277 lib/silcutil/silcbuffmt.[ch].
1279 * Redefined the SILC packet header to include the padding
1280 length. Affected file lib/silccore/silcpacket.[ch].
1282 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1283 length for maximum padding up to 128 bytes). Affected
1284 file lib/silccore/silcpacket.h.
1286 * Removed all backwards support for old 0.5.x MAC thingies.
1287 The SILC packet header change makes it impossible to be
1288 backwards compatible.
1290 * Send the ENDING packet with timeout in the backup resuming
1291 protocol. This is to assure that all routers has connected
1292 to the primary router. Affected file silcd/server_backup.c.
1294 * Changed the RNG to take the first IV from random data. It
1295 used to take it from zero actually. Changed the RNG also
1296 to use /dev/urandom during session. /dev/random is used
1297 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1299 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1301 * Changed the SILC packet header to have the first two bytes
1302 (the packet length) encrypted. Affected files aroung the
1303 code tree, lib/silccore/silcpacket.[ch]. Removed the
1304 SilcPacketCheckDecrypt callback. It is not needed anymore
1305 since the silc_packet_receive_process will determine now
1306 whether the packet is normal or special.
1308 * Implemented the unidirectional MAC keys. Affected files
1309 lib/silcske/silcske.c, silcd/protocol.c and
1310 lib/silcclient/protocol.c.
1312 * Implemented the packet sequence number to the MAC computation.
1313 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1314 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1315 lib/silcclient/protocol.c.
1317 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Allow backup router to announce servers. All servers
1320 announced by backup router are added to the global list
1321 automatically. Update hte server's socket to our primary
1322 router also when backup router announces a server.
1323 Affected file silcd/packet_receive.c.
1325 * Do not update the client->router in the function
1326 silc_server_udpate_clients_by_server if the client is on
1327 global list. We might fail to find any specific server
1328 for locally connected clients and local cell clients. They
1329 should still use the `from' and not `to' as client->router.
1330 This fixes backup router resuming protocol. Affected file
1331 silcd/server_util.c.
1333 * Decrease channel statistics count only if the channel
1334 deletion worked. Affected files are silcd/server.c and
1335 silcd/server_util.c.
1337 * Added silc_server_update_servers_by_server to update origin
1338 of all server entries. Used during backup router protocol.
1339 Affected files silcd/server_util.[ch], silcd/server.c. and
1340 silcd/backup_router.c.
1342 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1343 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1344 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1345 lib/silccrypt/silchmac.c.
1347 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * Assure that router cannot reroute the same channel message
1350 to the sender. Affected file silcd/packet_receive.c.
1352 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1354 * Made better checks that the channel message is not sent
1355 to the router it came from. Affected file is
1356 silcd/packet_send.c. Fixed memory leak too.
1358 * Announce informations for incoming router connection, but
1359 only after checking if it is replaced by backup router.
1360 Affected file silcd/packet_receive.c.
1362 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Fixed the backup resuming protocol to work in multiple
1365 router environment. Affected file silcd/server_backup.c.
1367 * Route packet only to one router in the function
1368 silc_server_packet_send_to_channel. Affected file is
1369 silcd/packet_send.c.
1371 * Fixed silc_server_send_notify_dest to set the broadcast
1372 flag. Fixed the silc_server_send_notify_topic to actually
1373 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1374 Affected file silcd/packet_send.c.
1376 * Changed the SFTP Filesystem interface. Changed the
1377 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1378 the filesystem operation function. The SilcSFTPFilesystem
1379 is now a context that is allocated by all filesystem allocation
1380 functions and it already includes the operations structure
1381 and filesystem specific context. It is given as argument
1382 now to the silc_sftp_server_start. This made the interface
1383 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1384 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1386 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Changed the backup router adding and getting interfaces
1389 in the server. The router that will be replaced by the
1390 specified backup router is now sent as argument. Affected
1391 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1394 * Added silc_net_addr2bin_ne to return the binary form of
1395 the IP address in network byte order. Affected files
1396 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1398 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Check for existing server ID in silc_server_new_server
1401 and in silc_server_connect_to_router_final and remove the
1402 old entry if it exists. Affected file silcd/packet_receive.c,
1405 * Send the channel message always to only one router, either
1406 in upstream or downstream. Affected file is
1407 silcd/packet_send.c.
1409 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Wrote the definition of the backup resuming protocol to the
1412 protocol specification.
1414 * Removed one redundant channel key generation from normal
1415 server during joining procedure. Removed one redundant
1416 channel key sending from server to router during joining
1417 procedure. Affected file silcd/command.c.
1419 * Made minor bugfixes to the backup router resuming protocol.
1420 Affected file silcd/server_backup.c, server.c.

1425 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1428 * Implemented the backup resuming protocol that is used to
1429 resume the primary router position in the cell after the
1430 primary router comes back online. Affected files
1431 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1432 and silcd/server_util.[ch].
1434 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Sleep two (2) seconds after sending QUIT command to server.
1437 Affected file lib/silcclient/command.c.
1439 * Assure that if outgoing data buffer is pending do not force
1440 send any data. Affected file silcd/packet_send.c.
1442 * Assure that if outgoing data buffer is pending do not force
1443 send any data. Affected file lib/silcclient/client.c.
1445 * Implemented the backup router support when the primary router
1446 goes down. The servers and routers can now use the backup
1447 router as new primary router without loosing connectivity.
1449 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1451 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1452 in the server to indicate disabled entry. All data read
1453 from the connection will be ignored and no data is sent
1454 for entry that is disabled. Affected files are
1455 silcd/idlist.h, silcd/server.c.
1457 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Created SFTP client and server test programs in the
1460 lib/silcsftp/tests directory.
1462 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Implemented memory filesystem (virtual filesystem) for
1465 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1468 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Implemented the SFTP (SSH File Transfer Protocol) to the
1471 lib/silcsftp. It includes SFTP client and SFTP server
1474 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Moved lib/silccore/silcprotocol.[ch] to the
1477 lib/silcutil library.
1479 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1480 take variable argument list pointer as argument. Affected
1481 file lib/silcutil/silcbuffmt.[ch].
1483 * Added silc_buffer_set function that is used to set data
1484 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1485 Affected file lib/silcutil/silcbuffer.h.
1487 * Changed various routines in the core library to use the new
1488 silc_buffer_set instead of allocating new buffer only for
1491 * Added 64-bit value formatting and unformatting support to the
1492 silc_buffer_[un]format routines. Affected file is
1493 lib/silcutil/silcbuffmt.[ch].
1495 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1496 to includes/bitmove.h.
1498 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * Fixed channel user mode saving in client library. Affected
1501 file lib/silcclient/command[_reply].c.
1503 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Defined the file transfer to the SILC Protocol. Added
1506 new packet type SILC_PACKET_FTP and defined File Transfer
1507 Payload. The mandatory file transfer protocol is SFTP
1508 (SSH File Transfer Protocol). Affected file in addition
1509 of the internet draft is lib/silccore/silcpacket.h.
1511 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1512 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1513 is used as part of backup router protocol when the primary
1514 router of the cell is back online and wishes to resume
1515 the position as primary router.
1517 * Redefined the MAC generation keys in the protocol. The
1518 same key is not used anymore in both direction. Both
1519 direction will now use different keys for sending and
1520 receiving. This fixes a potential security flaw. This
1521 change causes incompatibilities in the protocol.
1523 * Redefined also the MAC computation from the packet.
1524 An packet sequence number is now added to the MAC
1525 computation. This prevents possible replay attacks against
1526 the protocol. This change too causes incompatibilities
1529 Added `sequence' field to the SilcPacketContext to hold
1530 the current sequence number for the packet.
1532 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1534 * Added `created' field to the SilcIDListData in the file
1535 silcd/idlist.h to indicate the time when the entry was
1538 * Added `created' field to the SilcChannelEntry too. Affected
1539 file silcd/idlist.h.
1541 * Added `creation_time' aguments to all the announcement functions
1542 in the server. If it is provided then only the entries that
1543 was created after the provided time frame are actually
1544 announced. Affected file silcd/server.[ch].
1546 * The protocol says that the Channel ID's IP address must be
1547 based on the router's IP address. Added check for this in
1548 the silc_server_new_channel when processing incoming New Channel
1549 Payload. Affected file silcd/packet_receive.c.
1551 * Print out the correct version with --version in SILC client.
1552 Affected file irssi/src/silc/core/silc-core.c.
1554 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Fixed WHOWAS command to check for completnes of the client
1557 entry always, not just when the command is coming from client.
1558 Affected file silcd/command.c.
1560 * Added new function silc_server_packet_queue_purge to purge the
1561 outgoing data queue to the network. After the function returns
1562 it is guaranteed that the outgoing packet queue is empty.
1563 Affected file silcd/packet_send.[ch].
1565 * Purge the outgoing packet queue in the rekey protocol's final
1566 callback to assure that all rekey packets go to the network
1567 before quitting the protocol. Affected file silcd/server.c.
1569 * Added silc_client_packet_queue_parse as similar function as
1570 in server to the client library. The affected file is
1571 lib/silcclient/client.c.
1573 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1575 * Splitted silcd/server.c and created silcd/server_util.[ch]
1576 for utility functions.
1578 * Added new socket flag SILC_SF_DISABLED to indicate that the
1579 connection is open but nothing can be sent to or received from
1580 the connection. Affected file lib/silcutil/silsockconn.[ch].
1581 The checking for disabled socket is checked in the low level
1582 silc_socket_write and silc_socket_read functions.
1584 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Allow only nicknames and channel names that fits into the
1587 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1589 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * When processing JOIN command reply in server check that if
1592 the channel exists in our global list we'll move it the local
1593 list. Affected file silcd/command_reply.c.
1595 * Fixed the check whether client is joined on the channel already
1596 in JOIN command. Affected file lib/silcclient/command.c.
1598 * Fixed the JOIN command reply to check whether the channel
1599 already exists. Affected file lib/silcclient/command_reply.c.
1601 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Added silc_ske_status_string to map the SKE error numbers
1604 to readable strings. The affected files are
1605 lib/silcske/silcske[_status].[ch].
1607 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Do not show the private channels on the WHOIS channel list
1610 as it is not allowed by the protocol. The affected file is
1613 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Assure that the packet length digged from the actual packet
1616 is something sensible in the silc_packet_decrypt_rest_special
1617 in lib/silccrypt/silcpacket.c.
1619 * Free and NULL the allocated pointer in silc_hmac_alloc if
1620 the HMAC allocation fails. The affected file is
1621 lib/silccrypt/silchmac.c.
1623 * Print the selected security properties to the log files in
1624 the server. Affected file silcd/protocol.c.
1626 * Add SKE's reference counter even if calling the completion
1627 callback manually. Otherwise it goes negative, although it
1628 does not cause any problems. The affected file is
1629 lib/silcske/silcske.c.
1631 * Remove the client entry with short timeout after giving the
1632 KILL command. Affected file lib/silcclient/command.c.
1634 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1635 case all found clients are already disconnected (WHOWAS would
1636 found them) in the server. Affected file silcd/command.c.
1638 * Update the last_receive (time of last data received) to be
1639 updated only when received private or channel message so that
1640 the idle time showed in WHOIS makes more sense.
1642 * Added boolean field `valid' in to the SilcClientEntry in the
1643 client library to indicate whether the entry is valid or not.
1644 This fixes the nickname change bug on channel when changing
1645 the nickname to be same than the old (like nick to Nick) the
1646 nickname formatter doesn't set the new nick anymore to Nick@host.
1647 Affected file lib/silcclient/idlist.[ch].
1649 * Now actually fixed the nickname changing on disconnection.
1650 Added new function silc_change_nick to the Irssi SILC Client.
1651 Affected file irssi/src/silc/core/client_ops.c,
1652 irssi/src/silc/core/silc-nicklist.[ch].
1654 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1656 * Check that the public key exists in the GETKEY command before
1657 trying to encode it. Affected file silcd/command.c.
1659 * Print some notifications on received public keys with GETKEY
1660 command in the Irssi SILC Client. Affected files are
1661 irssi/src/fe-common/silc/module-formats.[ch],
1662 irssi/src/silc/core/client_ops.c.
1664 * Use IDENTIFY command to resolve the server information in the
1665 GETKEY command instead of INFO command. Affected file
1666 lib/silcclient/command.c.
1668 * All command reply functions in the client library now calls
1669 the pending command reply callbacks even if an error has
1670 occurred. The server has done this a long time and now it was
1671 time to move the client library to this as well. Now all
1672 errors can be delivered back to the pending command reply
1673 callbacks if necessary. Affected files are
1674 lib/silcclient/command[_reply].[ch].
1676 * Change the nickname on disconnection back to the username
1677 because in reconnect the server will enforce it to it anyway.
1678 Affected file irssi/src/silc/core/silc-servers.c.
1680 * Fixed a config file parsing bug in the Irssi SILC client.
1681 Affected file irssi/src/silc/core/clientconfig.c.
1683 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * When printing the channel mode on JOIN, verify that the
1686 channel key and channel's HMAC are valid. Affected file
1687 irssi/src/silc/core/client_ops.c.
1689 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1691 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1692 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1693 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1695 * Removed channel key rekey task deleting from the function
1696 silc_server_save_channel_key. Affected file silcd/server.c.
1697 Added explicit timeout task context instead that is used to
1698 delete the task if we are registering a new task before the
1699 new task has elapsed.
1701 * When channel key rekey occurs the client library now saves
1702 the old channel key for a short period of time (10 seconds) and
1703 is able to use it in case some is still sending channel
1704 messages encrypted with the old key after the rekey. Affected
1705 file lib/silcclient/[idlist.h|client_channel.c].
1707 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Added check to the silc_server_new_id_real to not accept
1710 new ID if it is the sender's own ID. Affected file is
1711 silcd/packet_receive.c.
1713 * Assure that we do not announce ourself or the one we've
1714 sending our announcements when we're router and are announcing
1715 servers to our primary router. Affected file silcd/server.c.
1717 * Fixed silc_server_command_identify_check_client to assemble
1718 correct WHOIS packet. It send corrupted WHOIS packet and
1719 caused problem with router to router connections. Affected
1720 file silcd/command.c.
1722 Fixed also silc_server_command_whois_check the same way
1723 as for the IDENTIFY command.
1725 * Added new SilcIDListStatus to the server in the SilcIDListData
1726 structure. The status now includes the current status of
1727 the entry (like registered, resolved etc.). Affected file
1728 silcd/idlist.[ch]. Defined a bunch of different status types
1729 as well. This replaced the old boolean registered field as well.
1731 Added resolve_cmd_ident field to the SilcClientEntry structure
1732 too so that if the entry is for example being resolved so
1733 another command may attach to the same pending command reply
1734 without requiring to resolve the same entry again. This concept
1735 should optimize the WHOIS and the IDENTIFY resolving under
1736 heavy load by taking away unnecessary resolving for entries
1737 that are being resolved already.
1739 Added support for adding multiple pending commands for one
1740 command idenfier. Affected file silcd/command[_reply].[ch].
1742 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1743 before deleting the data. Otherwise the hash table will have
1744 freed data in comparison functions. Affected file is
1745 silcd/command_reply.c.
1747 * Fixed silc_idlist_replace_client_id to add the new entry to
1748 the cache with NULL nickname. Otherwise there will be invalid
1749 memory as the nickname after the nickname is freed. Affected
1750 file silcd/packet_receive.c.
1752 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1753 saved into wrong slots because the previous number of entries
1754 was not taken into account. Affected file silcd/idlist.c.
1755 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1757 * If we are router and we receive JOIN notify to a channel that
1758 does not have any users then notified client is marked as the
1759 channel founder, as it is it. The affected file is
1760 silcd/packet_receive.c
1762 * Added to the extended hash table API's table_del_*ext functions
1763 the destructor as argument too, so that the caller can decide
1764 which destructor to use or whether to use destructor at all.
1765 Affected file lib/silcutil/silchashtable.[ch].
1767 * Fixed ID Cache purging. It actually deleted the entries from
1768 the hash table after the data was freed. The hash table ended
1769 up comparing freed memory. The affected file is
1770 lib/silccore/silcidcache.c.
1772 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Fixed Irssi SILC client's KILL command's HELP syntax.
1776 * The USERS command now resolves the detailed user information
1777 if the userinfo field is missing. Affected file is
1778 lib/silcclient/command_reply.c.
1780 * Do not print error in silc_file_read if the read file does
1781 not exist. Just silently return NULL. Affected file is
1782 lib/silcutil/silcutil.c.
1784 * Fixed the silc_log_output to not wine about NULL filename
1785 and to not create some bogus " " filename. Affected file is
1786 lib/silcutil/silclog.c.
1788 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Fixed various printing bugs on the user interface in the
1791 Irssi SILC Client. Minor changes that were forgotten from
1794 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Fixed the configure.in.pre and the compilation and distribution
1797 environment to support the new autoconf 2.52. That version is
1798 now required to compile the CVS trunk.
1800 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1803 to generally parse user@fqdn format strings. Affected file
1804 lib/silcutil/silcutil.c.
1806 * Added nickname_format and nickname_force_format fields to the
1807 SilcClientParams structure. The first one defines the format
1808 for the nicknames that the library will enforce if the receives
1809 multiple same nicknames. The second one is boolean value and
1810 can be used to force the library to always enforce the format
1811 to the nicknames regardles whether there are multiple nicknames
1812 or not. This configurable formatting was employed to flexibly
1813 support accessing multiple nicknames from the user interface.
1814 The userinterface can now set the nicknames to what ever format
1815 they prefer. Affected file lib/silcclient/silcapi.h.
1817 Added function silc_client_nickname_format to the file
1818 lib/silcclient/idlist.c. It performs the nickname formatting.
1820 Added new field `hostname´ to the SilcClientEntry context.
1821 It holds the hostname of the client. Affected file is
1822 lib/silcclient/idlist.h.
1824 * Irssi SILC Client sets the nicknames in nick@hostn format.
1825 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1826 irssi/src/silc/core/silc-core.c.
1828 The WHOIS printing now also shows both the real nickname and
1829 the formatted nickname so that user knows how to access the
1830 user if there are multiple same nicknames cached. Affected
1831 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1832 printing formatting too to take the hostname now as a separate
1833 argument. The Affected file is
1834 irssi/src/fe-common/silc/modules-formats.[ch].
1836 * Changed the silc_client_get_clients_local to accept the formatted
1837 nickname as argument. It accepts the real nickname too but the
1838 formatted nickname can be used to find the true entry from
1839 multiple entries. Affected file lib/silcclient/silcapi.h and
1840 lib/silcclient/idlist.c.
1842 * Added nickname_format_parse field to the SilcClientParams.
1843 It is a callback function provided by the application to parse
1844 the nickname out of the formatted nickname string. The library
1845 calls it to get the nickname from the formatted string. Since
1846 the application generally knows better the format of the nickname
1847 string it parses it instead of the library, even though library
1848 encodes the formatted string. If the callback function is not
1849 provided then the library will use the string as is. The
1850 affected file is lib/silcclient/silcapi.h.
1852 * All the nickname strings passed to the client library in
1853 commands are now expected to be formatted nickname strings.
1854 If the command does not support the formatted nickname string
1855 it will assume that the sent string is the actual nickname.
1856 Affected file lib/silcclient/command.c.
1858 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Added public key authentication support to OPER and SILCOPER
1861 commands in the client library. Affected file is
1862 lib/silcclient/command.c.
1864 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Changed the get_auth_methdod client operation to be asynchronous.
1867 It can be async if the application resolves the authentication
1868 method from the server during the negotiation. Added new
1869 SilcGetAuthMeth completion callback that the application will
1870 call after resolving the authentication method.
1872 Added function silc_client_request_authentication_method that
1873 the application can use to resolve the authentication method
1874 from the server. Added also SilcConnectionAuthRequest callback
1875 that the library will call after the server has replied. The
1876 application can call this function if it does not know the
1877 current authentication method.
1879 Affected files are lib/silcclient/client.c and
1880 lib/silcclient/silcapi.h.
1882 * The Irssi SILC client now automatically resolves the authentication
1883 method incase any configuration information is not present (and
1884 currently there never is). The affected file is
1885 irssi/src/silc/core/client_ops.c.
1887 * Fixed public key authentication from the client library.
1888 Affected file lib/silcclient/protocol.c. Changed also the
1889 protocol specification about the public key authentication in
1890 the connection authentication protocol. The actual data to be
1891 signed is now computed with a hash function before signing.
1893 * Fixed the public key authentication from the server as well.
1894 Affected file silcd/protocol.c.
1896 * Removed the mlock()'s from the memory allocation routines.
1897 Affected file lib/silcutil/silcmemory.c. The ./configure does
1898 not check anymore for the mlock(). Affected file is
1901 * Fixed USERS command in server to allow the execution of the
1902 command for private and secret channels if the client sending
1903 the command is on the channel. Affected file silcd/command.c.
1905 * Fixed silc_client_get_clients_local to return the clients
1906 count correctly. It could return wrong value. Affected file
1907 lib/silcclient/idlist.c.
1909 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1912 types. The assembler optimizations seemed not to like 64-bit
1913 data types. The assmebler optimizations thus are now enabled
1914 also for BSD systems as opposed to only enable them for Linux.
1916 * Do not check for threads at all on BSD systems. Affected
1917 file configure.in.pre.
1919 * Removed -n and -h options from the Irssi SILC Client since
1920 they are not used in silc.
1922 * Fixed the prime generation to assure that the first digit
1923 of the generated random number is not zero since our conversion
1924 routines does not like number strings that starts with zero
1925 digit. If zero digit is seen the random number is regenerated.
1926 This caused some corrupted RSA keys when the zero first digit
1927 was met. Affected file lib/silcmath/silcprimegen.c.
1929 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Fixed WIN32 configuration in the ./configure script.
1932 Fixed to include xti.h on environments that has it.
1933 Patches by Carsten Ilchmann and andrew.
1935 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1937 * Changed the silc_id_create_client_id to be collision
1938 resistant. It is now assured that there cannot be created
1939 two same client ID's. I suspect that some weird bugs in
1940 the server were actually caused by duplicate Client IDs.
1941 Affected file silcd/serverid.[ch]. A router receiving
1942 new ID now also assures and informs the sending server
1943 if the ID caused collision.
1945 * Changed the silc_id_create_channel_id to also assure that
1946 there are no collisions.
1948 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Statement about ignoring the Mutual Authentication flag when
1951 performing rekey with PFS was a bit misleading. It is ignored
1952 if it was set in the initial negotiation, it cannot be even
1953 set in the rekey. Fixed in the ke-auth draft. Started the
1954 new versions of the protocol drafts in the doc/.
1956 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1958 * Fixed a bug in silc_client_command_identify_save when saving
1959 new channel information. The channel name was no duplicated
1960 and caused crash on exit. Affected file is
1961 lib/silcclient/command_reply.c.
1963 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Fixed the getkey command handling in the server. Send just
1966 empty OK reply to the sender if the key could not be fetched
1967 (but everything else was ok, like the key just was not available).
1968 Changed the public key parameter to optional in the protocol
1969 specs so that empty OK reply can be sent. Affected file
1972 Added a message to Irssi SILC client to tell to user if the
1973 server did not return a public key.
1975 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * Fixed a channel key regeneration bug. It registered new
1978 timeout tasks exponentially until all system resources were
1979 used. Affected file silcd/server.c.
1981 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Added the SILC Document generator to the scripts/silcdoc.
1984 It can be used to generate the Toolkit Reference Manual out
1985 of the source tree. Internally it will also use the RoboDoc
1986 generator now imported in util/robodoc.
1988 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Added couple of return's in rekey protocol if error orccurred
1991 during the protocol. The execution must be terminated.
1992 Affected file silcd/protocol.c. Also, terminate the protocol
1993 always with timeout.
1995 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * The client's Client ID was created initally from the wrong
1998 nickname (it could have been in format nick@host) in the
1999 silc_server_new_client. Affected file silcd/packet_receive.c
2001 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Added some SILC_LOG_ERROR's to various error conditions
2004 if client could not be added to ID cache. Affected files
2005 silcd/packet_receive.c and silcd/server.c.
2007 * When client's sock->user_data is freed, NULL also the
2008 client->router and client->connection pointers. Added check
2009 for these pointers being NULL to various places around the
2010 code. Affected file silcd/server.c.
2012 * Added client->data.registered == TRUE checks to various
2013 places around the code to assure that unregistered client's
2014 are not handled when it is not allowed. Affected file
2017 * Added `bool registered' fields to all
2018 silc_idlist_[server|client]_get_* routines to indicate whether
2019 the fetched client needs to be registered or not. Affected
2020 file silcd/idlist.[ch].
2022 * Add your own entry as registered to the ID cache in the
2023 server. Affected file server.c.
2025 * Fixed a bug in silc_server_new_server. The SilcServer was
2026 set as the new server's context instead of SilcServerEntry.
2027 This naturally caused some weird bugs.
2029 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Do not delete the channel rekey task when adding it
2032 for in silc_server_create_channel_key.
2034 * Changed the silc_server_create_channel_key to return
2035 TRUE or FALSE to indicate the success of the channel key
2038 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Fixed MSVC++ project files and added missing files to
2041 Makefiles under win32/.
2043 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * Do not add TCP_NODELAY flag if the operating system
2046 does not have it defined. Affected files are
2047 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2049 * Fixed buffer overflow from Irssi SILC Client. Affected
2050 file irssi/src/fe-common/core/themes.c.
2052 * Fixed double free in client library in the file
2053 lib/silcclient/client.c when disconnecting from server.
2055 * Applied double free patch from cras to Irssi SILC client.
2056 Affected files irssi/src/core/[modules/expandos].c
2058 * Fixed the disconnection handling to Irssi SILC Client.
2059 The application must call silc_client_close_connection
2060 in ops->connect client operation in case of failure of
2061 the connection. Affected file is
2062 irssi/src/silc/core/client_ops.c.
2064 * Do not set sock->protocol to NULL in the function
2065 silc_client_close_connection after executing the protocol's
2066 final callback since the sock might not be valid anymore.
2067 Affected file lib/silcclient/client.c.
2069 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * Do not enable SILC_THREADS if the linking with libpthread
2072 did not happen. Affected file configure.in.pre.
2074 * Added notion to protocol specification that server must
2075 verify the sent authentication payload with CMODE when
2076 setting the channel founder key. Implemented it to the
2077 server. Affected file silcd/command.c.
2079 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Added _EXTRA_DIST SILC distribution variable to the
2082 distributions file. It is used to conditionally add extra
2083 files or directories to the specific distribution. Affected
2084 files ./prepare, Makefile.am.pre and distributions.
2086 Removed the `_' from the start of the distribution names.
2089 * Added README.WIN32 for instructions to compile the Toolkit
2092 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2094 * Fixed a double free in disconnection in the server. Affected
2095 file is silcd/server.c.
2097 * Fixed the lib/silcske/groups.c to work now also with GMP
2098 MP library. The string conversion did not work when using
2099 specific base and the base is indicated in the string as well.
2101 * Created win32/ directory which now includes MSVC++ specific
2102 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2103 It will appear only in the toolkit distribution
2105 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2107 * Changed the key material distribution function in case when
2108 the hash output is too short. The data is now concatenated
2109 a bit differently than it used to. Made the change to the
2110 SKE protocol specification.
2112 * Added better GMP detection to configure.in.pre. A patch
2115 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Fixed a minor bug in SKE that might cause some problem on
2118 some platforms. Affected file lib/silcske/silcske.c.
2120 * Added the cookie checking for initiator in the SKE. It checks
2121 that the responder returns the sent cookie unmodified. The
2122 affected file is lib/silcske/silcske.c. Added new SKE
2123 error type INVALID_COOKIE that can be sent during the
2124 negotiation. Fixed some memory leaks as well.
2126 * Added the "invalid cookie" error message to Irssi SILC client's
2129 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Added `task_max' field to the SilcClientParams to indicate
2132 the maximum tasks the scheduler can handle. If set to zero,
2133 default values are used. Affected file lib/silcclient/silcapi.h.
2135 * Fixed memory leaks in silc_client_close_connection. Affected
2136 file lib/silcclient/client.c.
2138 * Added silc_client_del_client_entry to client library to free
2139 all memory of given client entry. Affected file is
2140 lib/silcclient/idlist.[ch].
2142 * Added new functions silc_client_del_channel and
2143 silc_client_del_server to delete channel and server entries.
2144 Affected file lib/silcclient/[silcapi.h/idlist.c].
2146 * Removed silc_client_del_client_by_id from silcapi.h.
2148 * Fixed the INFO command to return the server's own info
2149 correctly when querying by Server ID. Affected file is
2152 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Removed the non-blocking settings in WIN32 code in the
2155 silc_sock_[read/write] and added SleepEx instead. Affected
2156 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2157 of input data is now checked with FIONREAD and ioctlsocket.
2159 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2161 * Call silc_schedule_task_del_by_context in the
2162 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2163 Affected file lib/silccore/silcprotocol.c.
2165 * Call silc_protocol_cancel for active protocols in the
2166 silc_server_close_connection if the funtion
2167 silc_server_free_sock_user_data has not been called.
2168 Affected file silcd/server.c.
2170 * Generic tasks cannot be deleted using the del_by_fd
2171 task deleting function since generic tasks does not match
2172 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2174 * Added a notion to SILCOPER help file that the SILCOPER works
2175 only on router server, not on normal server.
2177 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Added for WIN32 support for the new scheduler as well.
2180 Affected file lib/silcutil/win32/silcwin32schedule.c.
2182 * Fixed the SHA1 implementation to work on various platforms.
2184 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2187 API. It is part of the scheduler now. Everything else is
2188 as previously but some functions has changed their names.
2189 Checkout the lib/silcutil/silcschedule.h for the interface.
2190 Updated all applications to use the new interface. Affected
2191 files are lib/silcutil/silcschedule.[ch].
2193 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Found a bug in the SKE implementation. The HASH value,
2196 specified by the protocol, was not computed correctly. The
2197 public key of the responder was not added to the computation
2198 even though it is mandatory. Affected file lib/silcske/silcske.c.
2199 This unfortunately causes incompatibilities with older
2200 clients and servers.
2202 * Added WIN32 specific network init and uninit functions:
2203 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2204 the Winsock2. Affected file lib/silcutil/silcnet.h and
2205 lib/silcutil/win32/silcwin32net.c.
2207 * Set the socket always to nonblocking mode on WIN32 after
2208 reading data or writing data. Affected file is
2209 lib/silcutil/win32/silcwin32sockconn.c.
2211 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Fixed various compilation problems under WIN32. Affected
2214 files lib/silcutil/win32/silcwin32thread.c and
2215 lib/silcutil/win32/silcwin32schedule.c.
2217 * Removed all _internal.h #includes from public header
2218 files. Internal headers must never be included from
2221 Removed also the lib/silcske/payload_internal.h file.
2223 * All include files that may be needed (public and some others
2224 included by the public headers) by application developers are
2225 now copied to the ./includes directory. It does not copy any
2226 internal headers. Affected file Makefile.defines.pre and all
2227 Makefile.am's under lib/ and subdirs.
2229 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Do not change the ~/.silc directory's permissions automatically.
2232 Affected file irssi/src/silc/core/clientutil.c.
2234 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2236 * Do not cancel the protocol in silc_server_close_connection
2237 it might cause recursion. Now cancelled in the function
2238 silc_server_free_sock_user_data. Affected file silcd/server.c.
2240 * Fixed the silc_server_remove_clients_by_server to regenerate
2241 the channel keys correctly finally. Added also new function
2242 silc_server_remove_clients_channels to actually do it.
2243 Affected file silcd/server.c.
2245 * Fixed the silc_server_new_channel to not crash by giving
2246 wrong router to the new channel. Affected file is
2247 silcd/packet_receive.c.
2249 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2252 which is given as argument to the silc_client_alloc now.
2253 It can be used to configure the client and set various parameters
2254 that affect the function of the client.
2256 * The USERS command in server did not check whether the channel
2257 is private or secret. Affected file silcd/command.c.
2259 * Added new argument to the USERS command in protocol specification.
2260 The USERS command now can take the channel name as argument
2261 as well. Added support for this in client and server and
2262 updated the protocol specs.
2264 * Completed the GETKEY command in client. It can be now used
2265 to fetch also servers public key not only some clients.
2266 Affected files lib/silcclient/command[_reply].c.
2268 * Added silc_client_get_server to return server entry by the
2269 server name. Affected files lib/silcclient/silcapi.h and
2272 * Redefined the IDENTIFY command in protocol specification to be
2273 more generic. It now can be used to query information about
2274 any entity in the SILC Network, including clients, servers and
2275 channels. The query may be based either the entity's name
2276 or the ID. Added support for this in both client and server.
2278 Affected files silcd/command.c and lib/silcclient/command.c
2279 and command_reply.c.
2281 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2282 the _from_client and _from_server functions. Affected file
2285 * Added silc_client_get_channel_by_id_resolve to the file
2286 lib/silcclient/silcapi.h to resolve channel information by
2287 its ID. Added also silc_client_get_channel_by_id that
2288 does not resolve it from the server.
2290 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2292 * Added SilcServerEntry context into the client library
2293 to represent one server. The INFO command now allocates
2294 these to save the resolved server info. For now on the
2295 client library will also keep information about servers,
2296 connected and resolved with INFO.
2298 The INFO command now allocates the SilcServerEntry context
2299 and saves the server info there. The COMMAND_REPLY in
2300 the INFO now returns the parameters to application in
2301 same order as defined in the protocol specification.
2303 The entries are cached in the client->server_cache.
2305 * The INFO command is now issued after received the Client ID
2306 from the server. Affected file lib/silcclient/client.c.
2308 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2309 to the application as the mode changer might be server.
2310 It is guaranteed that NULL is not returned anymore to the
2311 application. Affected file lib/silcclient/client_notify.c.
2313 The ID Type is now also passed to the application so that
2314 it can check whether the returned entry is SilcClientEntry
2317 Added new function silc_client_get_server_by_id to return
2318 the server entry by ID. Affected files are the
2319 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2321 * Do not create the channel in the Irssi SILC Client when issuing
2322 the JOIN command but when received the sucessful JOIN command
2323 reply. Otherwise the channel might get created even though we
2324 could not join it. The Affected file is
2325 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2327 * Fixed a channel joining bug in router. The router must also
2328 check the channel modes, invite and ban lists etc. when serving
2329 the JOIN command sent by normal server. Affected file is
2330 silcd/command.c. The router now resolves the client's
2331 information from the server who sent the JOIN command if it
2332 does not know it, and processes the JOIN command only after
2335 * Changed the SilcCommandCb to take new argument; void *context2.
2336 Affected file lib/silccore/silccommand.h
2338 The second argument in the command callbacks in the server now
2339 includes the SilcServerCommandReplyContext if the command was
2340 called as pending command callback from the command reply.
2341 Otherwise it is NULL. When called as pending the status of the
2342 command reply will be checked and if it was erronous the
2343 error will be sent to the original sender of the command.
2344 This way the client always receives the error messages even
2345 though the server was actually the one who received the error
2346 when it resent the command to router, for example. Affected
2347 files silcd/command[_reply].[ch].
2349 * Fixed sending WHOWAS command's error message to client if
2350 the requested client could not be found. It was missing.
2353 * Changed the CMODE and CUMODE commands reply arguments in the
2354 protocol specification. The Channel ID is now sent in both
2355 of the commands to identify the channel. Implemented this
2356 new feature to the client and server. Affected files
2357 lib/silcclient/command_reply.c and silcd/command.c.
2359 * Made better checks for invite and ban lists in the JOIN
2360 command in server. Affected file silcd/command.c.
2362 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * The server now performs the incoming host IP/DNS lookup
2365 using the silc_socket_host_lookup and thus does not block
2366 the server anymore. Affected file silcd/server.c.
2368 * Completed the multi-thread support for SILC Scheduler in
2369 the lib/silcutil/silcschedule.c.
2371 * Fixed the configure.in.pre to detect the pthread correctly
2374 * Fixed a deadlock in silc_task_queue_wakeup in the file
2375 lib/silcutil/silctask.c.
2377 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Added new function silc_schedule_wakeup that is used in
2380 multi-threaded environment to wakeup the main thread's
2381 schduler. It needs to be used when a thread adds a new task
2382 or removes a task from task queues. After waking up, the
2383 scheduler will detect the task queue changes. If threads
2384 support is not compiled in this function has no effect.
2385 Implemented the wakeup mechanism to both Unix and WIN32
2386 systems. Affected files are lib/silcutil/silcschedule.[ch],
2387 lib/silcutil/unix/silcunixschedule.c and the
2388 lib/silcutil/win32/silcwin32schedule.c.
2390 * Added new function silc_task_queue_wakeup to wakeup the
2391 scheduler by the specified task queue. Affected file
2392 lib/silcutil/silctask.[ch].
2394 * The silc_socket_host_lookup_start now wakes up the scheduler
2395 after adding the timeout task. Affected file is
2396 lib/silcutil/silcsockconn.c.
2398 * The silc_socket_host_lookup is synchronous now if the threads
2399 support is not compiled in. However, the callback is still
2400 called asyncronously through the scheduler, anyway. Affected
2401 file lib/silcutil/silcsockconn.c.
2403 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2405 * Added new function silc_socket_host_lookup to perform
2406 asynchronous IP and FQDN lookups for the socket connection.
2407 Affected files lib/silcutil/silcsockconn.[ch].
2409 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2412 that may or may not compile the mutex support in.
2414 Changed the silc_mutex_alloc interface. It allocates the
2415 mutex now to the sent pointer and returns TRUE or FALSE.
2417 Affected file lib/silcutil/silcmutex.h.
2419 * Wrote the SILC Task Queue interface to support multi-threads.
2420 Affected file lib/silcutil/silctask.[ch].
2422 * Wrote the SILC Scheduler to support multi-threads. Affected
2423 file lib/silcutil/silcschedule.c.
2425 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2428 in lib/silcutil/win32/.
2430 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2432 * Defined SILC Mutex API and SILC Thread API and implemented
2433 them for Unix. Affected files are
2434 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2435 lib/silcutil/unix/silcunixmutex.c and
2436 lib/silcutil/unix/silcunixthread.c.
2438 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Fixed the silc_server_remove_clients_by_server's channel
2441 key re-generation. The hash table handling was incorrect
2442 and would not work with many channels. Affected file is
2445 * Fixed some memory leaks around the server code.
2447 * Rewrote the silc_server_get_users_on_channel to support IPv6
2448 based Client ID's. Affected file silcd/server.c.
2450 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2451 specification. However, a separate document must be written
2452 to define the detailed signing procedure and the payload
2453 associated with the flag. Defined the flag to the
2454 lib/silccore/silcchannel.h as well.
2456 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Changed the dynamic tables to static size tables in the
2459 lib/silccrypt/silchmac.c.
2461 * Removed GCC dependencies from the code. A patch by cras.
2463 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Do not show the error "Error receiving packet bla bla"
2466 in server if it really was not an error (-2 means that reading
2467 is pending). Affected file silcd/server.c.
2469 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Fixed a possible crash in silc_server_remove_clients_by_server
2472 in silcd/server.c. Fixed there also some memory leaks.
2474 * Fixed the silc_idlist_replace_client_id. It could replace
2475 wrong key in the hash table. Affected file silcd/idlist.c.
2477 * Do not check whether there are global users on the channel
2478 if the channel->global_users is FALSE. Affected functions
2479 silc_server_remove_from_one_channel and
2480 silc_server_remove_from_channels in silcd/server.c. Also,
2481 do not check if the removed client is local as we can be
2482 sure that global client was not removed from the channel
2483 and checking for global users is not needed.
2485 * The silc_server_remove_clients_by_server now re-generates
2486 the channel keys correctly for those channels that had
2487 clients removed from them. Affected file silcd/server.c.
2489 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Found the reason of random crashes in the server. We weren't
2492 ignoring the SIGPIPE signal (which can be sent in write())
2493 and it crashed the server. Affected file silcd/silcd.c.
2495 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Assure that sock->user_data is not NULL in the function
2498 silc_server_packet_send in silcd/packet_send.c.
2500 * Disconnect the remote connection if it could not be added
2501 to any ID lists in the server. The affected file is
2504 * Check in silc_server_packet_send[_real/dest] that the
2505 socket is not disconnecting and ignore the data if it is.
2506 Affected file silcd/packet_send.c.
2508 * Define inline to __inline on native WIN32 compilation.
2509 Affected file includes/silcwin32.h.
2511 * Added some explicit type casts for inline code since MSVC
2512 require them. Affected files lib/silcutil/silcbuffer.h,
2513 lib/trq/silcdlist.h and lib/trq/silclist.h.
2515 * Print warning in log files from now on if the packet
2516 decryption fails. Affected file silcd/server.c.
2518 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Changed the `say' client operation's interface to accept
2521 new `type' argument to indicate the type of the message sent
2522 by the library. The application may filter the library's
2523 messages according the type. The affected file is the
2524 lib/silcclient/silcapi.h.
2526 * Added two new functions to lib/silcclient/silcapi.h:
2527 silc_client_del_client and silc_client_del_client_by_id.
2528 Affected file lib/silcclient/idlist.c.
2530 * Moved the clientincludes.h from includes/ to silc/ and
2531 serverincludes.h from includes/ to silcd/.
2533 * The modes for the CMODE and CUMODE are now passed as
2534 uint32 for application with COMMAND_REPLY. The affected
2535 file is lib/silcclient/command_reply.c.
2537 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * /WHOIS without arguments shows client's own information.
2540 Affected file lib/silcclient/command.c.
2542 * Changed PING to not accept any arguments. The specs
2543 says that client can ping only the connected server so
2544 requiring an argument is not needed. Affected file is
2545 lib/silcclient/command.c.
2547 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2549 * Fixed a fatal bug in private message sending and reception
2550 encryption and decryption when using private message keys.
2551 The implementation was incorrect and did not follow the
2552 specification. It causd that some of the message were
2553 lost since it did not use the sending and receiving keys
2554 as the protocol suggests. This has been fixed and will cause
2555 incompatibilities with older clients when sending private
2556 message encrypted with private message keys. Affected files
2557 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2558 and various other in Irssi SILC Client.
2560 Added `responder' boolean argument to the functions
2561 silc_client_add_private_message_key[_ske] to indicate when
2562 the key is added as responder or initiator of the key
2565 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Removed the silc_ske_check_version function and created
2568 a SilcSKECheckVersion callback. Added also a function
2569 silc_ske_set_callbacks that is now used to set all SKE
2570 callbacks. The callback functions are not given to
2571 the SKE functions anymore, but this function is used to
2574 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2576 * Added `silc_version' argument to the silc_client_alloc
2577 to define the version of the application for the library.
2578 The library will use the version string to compare it
2579 against the remote host's (usually a server) version
2580 string. Affected file lib/silcclient/silcapi.h
2582 * Added the KE protocol context to Key Agreement context
2583 in client library so that we can abort the SKE if it
2584 is in process when we get timeout. Affected file is
2585 lib/silcclient/client_keyagr.c.
2587 * Do not resolve the client ID forever if it returns in the
2588 first time that such client does not exist. This was done
2589 for example with private message. Affected file is
2590 lib/silcclient/client_prvmsg.c.
2592 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Do not add regex.h for WIN32. The affected file
2595 includes/silcincludes.h.
2597 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2598 not work yet 100%. It generates the DLL's automatically
2599 when compiling with --with-win32 under cygwin.
2601 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * lib/contrib/regex.c is not compiled on WIN32.
2605 * Added silc_net_get_socket_opt function to the
2606 lib/silcutil/silcnet.h.
2608 * Added includes/silcwin32.h for WIN32 specific includes
2611 * Do not use ptime structure or any of the posix process
2612 functions on WIN32 in lib/silccrypt/silrng.c.
2614 * Added silc_gettimeofday to provide generic function
2615 for struct timeval on all platforms. Added the function
2616 to lib/silcutil/silcutil.h.
2618 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2621 library as they clearly belong there. As a plus side we
2622 can make the actual socket connection routines platform
2625 Added also new generic function silc_socket_read and
2626 silc_socket_write (that used to be silc_packet_[read/write].
2627 The implementation of these are platform specific.
2629 * Added WIN32 specific routines of silc_socket_[read/write]
2630 to lib/silcutil/win32/silcwin32sockconn.c.
2632 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Added preliminary support for native WIN32 compilation under
2635 cygwin (using the -mno-cygwin option for GCC) to the
2636 ./configure.in.pre. The --with-win32 now prepares the
2637 compilation for native WIN32.
2639 * Rewrote the SILC Scheduler interface in the file
2640 lib/silcutil/silcschedule.h. The scheduler is now context
2641 based and does not have anymore any global static scheduler.
2642 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2643 and created lib/silcutil/win32 directory for WIN32 based
2646 * Added Unix specific network routines to the
2647 lib/silcutil/unix/silcunixnet.c and the old
2648 lib/silcutil/silcnet.c includes now only generic routines.
2650 Added WIN32 specific network routines to the
2651 lib/silcutil/win32/silcwin32net.c.
2653 * Added Unix specific utility functions from the
2654 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2656 * Added WIN32 SILC Scheduler to the file
2657 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2660 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Do not handle JOIN notify in the server if the target client
2663 is not registered (idata->registered == FALSE). The affected
2664 file is silcd/packet_receive.c.
2666 * Update the nickrec->founder in event_cumode in the Irssi SILC
2667 client. Affected file irssi/src/silc/core/silc-channels.c.
2669 * Fixed the CUMODE_CHANGE notify handling in the server when
2670 server and router are announcing their clients on channels.
2671 Now the mode changes are saved and notified correctly. The
2672 affected file is /silcd/packet_receive.c.
2674 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2675 They really did not replace the cache entry in the ID Cache.
2676 Now they do that. Affected file silcd/idlist.c.
2678 * Fixed the KICK notify handling in the Irssi SILC client to
2679 update the channel records so that the kicked client does not
2680 appear to be on the channel. The affected file is
2681 irssi/src/silc/core/silc-channels.c.
2683 * Always update the conn->current_channel when executing command
2684 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2686 * Fixed the KILL notify handling in Irssi SILC client to remove
2687 the killed client on all channels.
2689 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Fixed the silc_parse_command_line to remove extra spaces
2692 from the start and end of the arguments. Affected file is
2693 lib/silcutil/silcutil.c.
2695 * Cancel and free any active protocol in the function
2696 silc_server_close_connection. Affected file silcd/server.c.
2698 * Cancel and free any active protocol in the function
2699 silc_client_close_connction. Affected file is
2700 lib/silcclient/client.c.
2702 * Do not execute the KILL command for clients that are in
2703 history (ie. they are not in the network). Affected file is
2706 * Fixed KILL notify handling, client does not crash anymore.
2707 Affected file irssi/src/silc/core/silc-channels.c.
2709 * Reduced the default packet buffer size from 2048 to 1024 in
2710 lib/silccore/silcpacket.c.
2712 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2713 counter to the SKE context that is incresed when the SKE library
2714 performs async operation outside the library. If the outside
2715 process frees the SKE context and FREED status will be set
2716 and the library will detect after the sync operation that the
2717 libary is freed. The affected files are
2718 lib/silcske/silcske[_status].[ch].
2720 * Resolve the client entry information in the function
2721 silc_client_channel_message to assure that NULL pointer is not
2722 passed as client entry to the application. */
2724 * Fixed the task timeout calculation to assure that there is
2725 never negative timeouts. The affected file is
2726 lib/silcutil/silcschedule.c.
2728 * Fixed the channel user mode notification sending in server.
2729 It was sent point-to-point to the router (or to server by router)
2730 but it needs to be destined to a channel. The routines now
2731 supports sending the channel user mode notifys to the channels
2732 when announcing clients and channels. Affected files are
2733 silcd/server.c and silcd/packet_receive.c.
2735 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2736 It did not actually replace the old channel entry in the cache.
2737 Affected file lib/silcclient/client_notify.c.
2739 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Fixed a possible crash in silc_packet_send_prepare. It now
2742 assures always that there is enough space in the buffer and
2743 at the tail area of the buffer (for MAC).
2745 Fixed the inbound buffer reallocation in silc_packet_read.
2746 It was old code and did not handle the reallocation correctly.
2749 The affected file is lib/silccore/silcpacket.c.
2751 * Fixed buffer overflow in silc_parse_nickname in the file
2752 lib/silcutil/silcutil.c.
2754 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * make install generates new server keys only if there is not
2759 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2762 Added check that if the NOREPLY is set then we will not send
2763 the away message. This avoids infinite loop of away messages
2764 if both clients are away. The affected file is
2765 lib/silcclient/client_prvmsg.c.
2767 * Fixed client crash if /NICK was given without arguments.
2768 Affected file lib/silcclient/command.c.
2770 * Server does not send the invite list in INVITE command back
2771 to the client if the list was not altered. Added this notion
2772 to the protocol spec as well. Affected file silcd/command.c.
2774 Fixed possible crash in INVITE command by checking the
2775 value of silc_server_get_client_route command.
2777 * Fixed the INVITE notify type handling. The arguments are now
2778 taken in correct order and client does not crash. The affected
2779 file is irssi/src/silc/core/silc-channels.c.
2781 Removed the "Inviting xxx to channel" message from the
2782 client library away and let the application handle it.
2783 Affected file lib/silcclient/command.c. Added that message
2784 to Irssi SILC client's message formats.
2786 * Fixed CMODE command crash in client. It now checks the
2787 amount of arguments correctly and does not crash. The affected
2788 file is lib/silcclient/command.c.
2790 * Do not create new channel automatically in silc_channels_join
2791 but check whether the channel by that name already exists.
2792 Affected file irssi/silc/core/silc-channels.c.
2794 * Do not send the SERVER_SIGNOFF to router if the disconnected
2795 entity was the router. Affected file silcd/server.c.
2797 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2798 SILC client as it was missing from there.
2800 Added the handling of the KICK notify to the Irssi SILC client
2801 as it was missing. Added "you have been kicked" message to
2802 Irssi SILC client's message modules formats.
2804 Added the handing of the KILL notify to the Irssi SILC client
2805 as it was missing. Added the kill message module formats
2808 The affected file is irssi/src/silc/core/silc-channels.c.
2810 * The router did not save the channel mode the server announced.
2811 Affected file silcd/packet_receive.c.
2813 * Fixed a possible crash in INFO command in server. If the
2814 server did not provide the server info it crashed. Affected
2815 file silcd/command.c.
2817 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Fixed the GETKEY command in the server to check also the
2820 global list. Otherwise the GETKEY would not work correctly
2821 in normal SILC server. Affected file silcd/command.c.
2823 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Fixed GETKEY crash, it crashed if the command did not succseed.
2827 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2830 is now real and not just an macro interface to GMP.
2832 Removed the entire GMP from the source tree and imported new
2833 NSS MPI library instead. Reason for removing GMP is that it is
2834 extremely large and compiles extremely slow. The NSS MPI
2835 is only a few files and compiles in less than 10 seconds.
2836 The speed is also about the same as GMP. The MPI is imported
2837 to lib/silcmath/mpi.
2839 If the system has GMP installed we will still use the GMP.
2840 If it is not then the NSS MPI will be compiled.
2842 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Merged a long nickname (127 characters long) crash bugfix from
2845 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2847 * Merged a freed memory reference bugfix from Irssi CVS tree.
2848 Affected file irssi/src/core/commands.c.
2850 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added the server's public key sving and verification to the
2853 server when performing the SKE. This was missing and the
2854 remote server's (or router's) public key was accepted without
2855 checking whether we have it previously or trust it at all.
2856 Affected file silcd/protocol.c.
2858 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2860 * Check in the silc_server_timeout_remote if protocol is active
2861 and make sure that the protocol's final callback is called so
2862 that all memory if freed. Affected file silcd/server.c.
2864 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * silc_server_whois_send_reply crashed the server if the nickname
2867 was 127 characters long. Affected file silcd/command.c.
2869 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2871 * Added sanity check to the silc_server_new_client. If the hostname
2872 is provided inside username then check that the provided hostname
2873 really is the same as the resolved one. If the hostname was not
2874 resolved then check it from the public key. Affected file is
2875 silcd/packet_receive.c.
2877 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2878 if the server disconnected us and the connection is not valid
2879 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2881 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2882 the library to the lib/silcutil/silcutil.[ch].
2884 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Close log file after open. Affected file
2887 lib/silcutil/silclog.c.
2889 * Check whether sock == NULL in silc_client_send_packet and return
2890 if it is. Affected file lib/silcclient/silcclient.c.
2892 * Check rec->entry == NULL in the Irssi SILC Client before
2893 sending the channel message. Affecte file is
2894 irssi/src/silc/core/silc-servers.c.
2896 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2898 * Merged a splitted window bugfix from Irssi CVS tree. The
2899 affected file is irssi/src/fe-text/textbuffer-view.c.
2901 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2902 It did not print nickname.
2904 * Improved the distributions system a bit.
2906 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2909 irssi/src/fe-text/gui-window.c.
2911 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2912 to in-active server. The affected file is
2913 irssi/src/silc/core/client_ops.c.
2915 * Resolve the client in USERS command reply if the entry does
2916 not have username resolved. The affected file is
2917 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2918 command to WHOIS command to really resolve stuff. The USERS
2919 is not used any more in any critical section so WHOIS can
2920 be used even though it might be slower than IDENTIFY.
2922 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2925 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2927 * Changed the protocol API a bit more consistent in the
2928 lib/silccore/silcprotocol.[ch].
2930 * Changed the following headers to ROBODoc format:
2932 lib/silccore/silcpayload.h
2933 lib/silccore/silcprotocol.h
2934 lib/silccore/silcsockconn.h
2936 All core library headers are now formatted.
2938 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Fixed a bug in Irssi SILC client; do not show that you are
2941 server/router operator if you really are not. Affected file is
2942 irssi/src/silc/core/client_ops.c.
2944 * Renamed silc_command_free_payload to silc_command_payload_free.
2945 Affected file lib/silccore/silccommand.h
2947 * Added silcmath.h to include the prototoypes of various routines
2948 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2951 * Changed the following headers to ROBODoc format:
2953 lib/silccore/silcchannel.h
2954 lib/silccore/silccommand.h
2955 lib/silccore/silcid.h
2956 lib/silccore/silcidcache.h
2957 lib/silccore/silcmode.h
2958 lib/silccore/silcnotify.h
2959 lib/silccore/silcpacket.h
2960 lib/silcmath/silcmath.h
2962 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Added checking to the server code not to start the server if
2965 ciphers and stuff are not configured properly. Affected files
2966 silcd/serverconfig.[h] and silcd/server.c.
2968 * Changed the layout of the header files of the public interfaces
2969 in the SILC libraries. The new layout supports ROBODoc
2970 documentation tool (and some others) so that it is easy to create
2971 a library reference manual. All the other headers and source
2972 code must still follow the CodingStyle document. Also source
2973 code must not include these ROBODoc stuffs, only the headers.
2974 Furthermore, all public interface headers must now be named
2975 by using `silc' prefix, example: silcapi.h, silccipher.h.
2976 Some files were renamed due to this. All the other headers
2977 must not be used as public interfaces. I will update the
2978 CodingStyle document later. Changed following headers, so far:
2980 lib/silcclient/silcapi.h
2981 lib/silccore/silcauth.h
2982 lib/silccore/silcprivate.h
2983 lib/silccrypt/silcdh.h
2985 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Removed silc_client_packet_send_flush from the client library
2990 as it is not needed. Affected file lib/silcclient/client.[ch].
2992 * Added printing of message of unresolved authentication method
2993 to the Irssi SILC client. Added it to the module formats.
2994 Removed the same message from the client library.
2996 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added new distribution feature, DISTLABEL. Every distribution
2999 can define own preprocessor label that can be used in the
3000 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3001 file distributions, acconfig.h.pre and prepare.
3003 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Added Makefile.defines_int to include the actual definitions
3006 for Makefile.defines.in. Tested the new distribution system,
3007 created distributions and tested installation.
3009 * Added AWAY message printing to the Irssi SILC client. Added
3010 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3012 * Added SCONNECT command to call the SILC's CONNECT command.
3013 Cannot use CONNECT directly since Irssi uses that internally.
3014 Affected file irssi/src/silc/core/silc-servers.c.
3016 Added ACTION local command. It is same as ME command but takes
3017 the channel as mandatory argument.
3019 Rewrote some of the Irssi's help files to suite for SILC
3022 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Added Makefile.defines[.in] that should for now on be included
3025 in all Makefile.am file in the source tree. That file includes
3026 all common compilation definitions for SILC source tree.
3028 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Minor changes to the ./prepare script to change the package
3031 name according the distribution name to the configure.in.
3033 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Created new distribution system. Added file `distributions'
3036 that defines all the distributions that can be created out of
3037 the SILC source tree. The ./prepare script now reads that
3038 file to determine how to prepare the distributions. The
3039 first argument to the ./prepare is the name of the distribution
3040 and second is the version of the distribution. If given
3041 without arguments it creates the default (toolkit) distribution
3042 with the default version (defined in ./prepare).
3044 All Makefile.am files that are subject to the distributions
3045 are now named as Makefile.am.pre. These are ./Makefile.am
3046 and lib/Makefile.am. Others may be changed later.
3048 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added invite list, ban list, some key management and connection
3051 error message printing to module formats in the Irssi SILC client.
3053 * Added new silc_client_set_away_message to set the away message
3054 that is back to the person who sent private message. The
3055 affected file lib/silcclient/silcapi.h and the
3056 lib/silcclient/client_prvmsg.c.
3058 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3060 * Fixed the private message sending in the Irssi SILC client,
3061 added local command KEY to the Irssi SILC client.
3063 Added key management and key agreement message formats to the
3064 irssi/src/fe-common/silc/module-formats.[ch].
3066 Added USERS (alias WHO) printing, server/router operator
3067 indication and LIST command printing to the module formats.
3069 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Fixed channel joining notify handling, cumode notify handling
3072 from Irssi SILC client.
3074 * Added SILC specific module-formats to the Irssi SILC client so
3075 that SILC specific message hilighting, colors etc is possible.
3076 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3078 Added channel mode, channel user mode, actions, notices,
3079 whois and whowas printing to the the module-formats.c.
3081 * Fixed a bug in channel deletion in the server. The channel
3082 is not left to the cache even if the channel founder auth mode
3083 is set when there are no users anymore on the channel. Affected
3084 file silcd/server.c.
3086 * The silc_net_localhost now resolves the entire hostname including
3087 the domain name. Affected file lib/silcutil/silcnet.c.
3089 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Changed the ask_passphrase client operation to be ascynchronous.
3092 It has now a completion callback and a context that the
3093 application must call after it has got the passphrase from
3094 the user. Affected files lib/silcclient/silcapi.h,
3095 lib/silcclient/protocol.c, lib/silcclient/command.c and
3098 Added SilcAskPassphrase callback that the application calls
3099 to deliver the passphrase to the library.
3101 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3102 The public key verification and especially a certificate
3103 verification is asynchronous procedure.
3105 Added new SILC_SKE_STATUS_PENDING status to indicate the
3106 request is pending and a callback will be called to finalize
3109 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3110 indicate that remote end did not send its public key (or
3111 certificate), even though we require it. Added check for this
3112 condition in the SKE. This was a security bug, now fixed.
3114 Defined new SilcSKEVerifyCbCompletion callback that is called
3115 when the verification process is completed.
3117 The affected files lib/silcske/silcske_status.h and
3118 lib/silcske/silcske.[ch].
3120 * Changed the verify_public_key client operation to be async
3121 as well. Defined SilcVerifyPublicKey callback that is used to
3122 indicate the success of the public key verification process.
3124 Changed the server and client to use the new async client
3127 * Changed the Irssi SILC client's internal scheduler to be called
3128 twice as many times as it used to be. As a result the client
3129 should be a bit faster now. Affected file is
3130 irssi/src/silc/core/silc-core.c.
3132 * Added support to Irssi SILC client of asynchronous public key
3133 verification and passphrase inquiry. Affected file is
3134 irssi/src/silc/core/silc-core.c.
3136 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3138 * Do not say "You have left channel %s" in client library.
3139 Moved it to the application. Affected files are
3140 lib/silcclient/command.c and silc/client_ops.c.
3142 * Fixed silc_client_get_clients. Command context was not
3143 duplicated and was freed memory in the callback. Affected
3144 file lib/silcclient/idlist.c.
3146 * Do not say "you are now talking..." on JOIN command in the
3147 client library. The appliation must handle it.
3149 * Do not say ".. changed topic to" in command reply in the
3150 client libary. The application must handle it.
3152 * Fixed TOPIC command sending in the client library.
3154 * Fixed a memory leak in silc_client_command_free in the file
3155 lib/silcclient/command.c.
3157 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3159 * Imported a modified version of Irssi client to the source tree.
3160 The Irssi will be used to create a new client called
3161 Irssi SILC. Imported to irssi/.
3163 Added silc_core_init_finish function to the Irssi. Affected
3164 file irssi/configure.in.
3166 A lot changes in the Makefile.ams around the irssi tree.
3168 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Do not rehash if the new size is same as the old size of the
3171 hash table, in the silc_hash_table_rehash*. The affected file
3172 lib/silcutil/silchashtable.c.
3174 * Replaced hash_table_del_by_context calls from the server
3175 (when channel->user_list and client->channels) to the
3176 hash_table_del as it is sufficient and faster.
3178 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3180 * Added silc_hash_table_list, silc_hash_table_get and the
3181 SilcHashTableList structure to provide an alternative way to
3182 traverse the hash table. The affected files are
3183 lib/silcutil/silchashtable.[ch].
3185 * Changed the server's idlist routines to use the hash table
3186 routines to optimize the code.
3188 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Replaced the client entry's `channel' list and channel entry's
3191 `user_list' list to hash tables for optimized lookup. Changed
3192 the code to use the hash table interface around the code.
3193 Affected file lib/silcd/idlist.[ch].
3195 * Added `auto_rehash' boolean argument to the function
3196 silc_hash_table_alloc to indicate whether the hash table should
3197 auto-rehash when it thinks is appropriate time. It will
3198 increase the hash table size if the there is twice as much
3199 entries in the table than the size of the table, and will
3200 decrease the size if there are twice as less entries than
3201 the size of the table.
3203 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3207 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * silc_idcache_purge_by_context deletes the entry now by context
3210 as it is supposed to do. Affected file lib/silccore/idcache.c.
3212 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3213 client is not anymore valid (WHOWAS givens the info) and not
3214 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3216 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Removed the `data' and `data_len' arguments from the ID Cache
3219 interfaces and added `name' argument. ID Cache does not handle
3220 anymore the binary data only a names associated with given ID.
3222 * When hashing a Client ID with silc_hash_id the entire ID is
3223 not hashed anymore, instead only the hash of the Client ID is
3224 hashed. This way we can access the Client ID from the cache
3225 with Client ID but with the hash of the ID (which is a hash of
3226 the nickname) as well without any difference in performance.
3228 Added also silc_idcache_find_by_id_one_ext to do one on one
3229 searching when we have the actual ID. Added also function
3230 silc_hash_client_id_compare. The affected files are
3231 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3233 * When hashing the name associated with a ID it is always done
3234 in lowercase. This way we can access the cache without worrying
3235 about case-sensitivity, even though, for example nicknames are
3238 * Fixed a bug in server with channel message sending. It put
3239 wrong ID type as destination ID. The affected file
3240 silcd/packet_send.c.
3242 * silc_idcache_del_by_context now deletes from all hash tables
3243 by context. Affected file lib/silccore/idcache.c.
3245 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Changed the client library to use the new ID Cache interface.
3248 Changes around the source tree.
3250 * Added silc_hash_table_rehash_ext to rehash with specific
3251 hash function. Affected file lib/silcutil/silchashtable.[ch].
3253 * Added silc_hash_string_compare to compare two strings in the
3254 hash table. Affected file lib/silcutil/silcutil.[ch].
3256 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * Added new function silc_idcache_del_by_context into the
3259 lib/silccore/idcache.[ch].
3261 * Changed the server's ID list routines to use the new ID Cache
3262 interface. Changes around the source tree.
3264 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3266 * Added silc_hash_table_del[_by_context]_ext functions in to the
3267 lib/silcutil/silchashtable.[ch].
3269 Removed silc_hash_table_find_all* routines and added new
3270 silc_hash_table_find_foreach to replace them.
3272 Added silc_hash_table_replace_ext function as extended
3273 replacing function. Separated the simple hash table interface
3274 from the extended hash table interface in the file
3275 lib/silcutil/silchashtable.h.
3277 * Fixed minor bugs and changed it to use some of the new
3278 hash table functions in lib/silccore/idcache.c
3280 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Added new function silc_hash_table_find_all to return all keys
3283 in the hash table by the specified key. As the hash table is
3284 collision resistant it also makes it possible to have several
3285 duplicate keys in the hash table. This function may be used to
3286 find all of the keys from the hash.
3288 Added user_context arguments to the SilcHashFunction,
3289 SilcHashCompare and SilcHashDestructor to deliver user specified
3292 Added new fuctions silc_hash_table_find[_all]_ext to do
3293 extended lookup with specified hash and compare functions and
3294 specified user contexts.
3296 Added new function silc_hash_table_add_ext to add the key
3297 with specified hash function and user context.
3299 Added new function silc_hash_table_foreach to traverse all
3300 entrys in the hash table. Added SilcHashForeach callback
3303 Added new function silc_hash_table_del_by_context to delete
3304 the entry only if the context associated with the key matches.
3306 Affected files are lib/silcutil/silchashtable.[ch].
3308 * Removed silc_hash_[server/client/channel]_id and added just
3309 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3310 silc_hash_id_compare to compare two ID's using as the hash table
3311 comparison function. Added also silc_hash_data to hash
3312 binary data and silc_hash_data_compare to compare it.
3314 * Removed silc_idlist_find_client_by_hash as it is not needed
3315 anymore. Affected file silcd/idlist.[ch].
3317 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3318 to use internally the SilcHashTable. The new ID Cache is a lot
3319 faster than the old one. Some of the ID Cache interface was also
3320 rewritten and obsolete and stupid functions were removed.
3322 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3324 * Added entry_count field to the SilcHashTable to keep the number
3325 of the entries in the table. Implemented the function
3326 silc_hash_table_rehash. Added new function
3327 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3329 Fixed a minor bug in silc_hash_table_free.
3331 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3332 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3333 into the lib/silcutil/silcutil.[ch].
3335 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Implemented a collision resistant hash table into the
3338 lib/silcutil/silchashtable[ch]. See the header and the source
3339 for the SilcHashTable API.
3341 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Merged dotconf version 1.0.2 into lib/dotconf.
3345 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Do not compile anything in lib/silcsim/* if the SIM support
3348 is not enabled. The tree should now compile without problems
3351 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Compiled the SILC under cygwin. Compiled and tested briefly
3354 without problems. More tests needed. The SIMs didn't compile
3357 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3359 * Fixed possible crash in silc_get_username in the
3360 lib/silcutil/silcutil.c.
3362 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Fixed a va_arg in silc/client_ops.c.
3366 * Oops, RC5 routines were named AES and caused some problems
3367 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3369 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3371 * Added new SilcIDIP structure into the lib/silccore/id.h and
3372 replaced the old `ip' fields from all SILC ID's to that type.
3373 This is a step towards IPv6 support.
3375 The silc_id_get_len takes now the ID as an extra argument.
3376 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3377 both IPv4 and IPv6 based ID's.
3379 The affected files are lib/silccore/id.[ch] and other files
3380 around the tree using these routines.
3382 * Removed the ID length arguments in server from various
3383 silc_server_send_notify_* routines -> they are not needed
3386 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3388 * Fixed memory leak in silc_encode_pem_file in the file
3389 lib/silcutil/silcutil.c.
3391 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Check minor version as well in the SKE. Affected files are
3394 silcd/protocol.c and lib/silcclient/protocol.c.
3396 * Added --identifier option to the server so that an identifier
3397 can be when creating the public key for the server. Affected
3398 file is silcd/silcd.c.
3400 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3401 lib/silccrypt/silcpkcs.c.
3403 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Register default ciphers and stuff when using -C option with
3406 the server. Affected file sildc/silcd.c.
3408 * Put back the servers public key filename format, it is better
3409 than the new one. For now, the client keys are saved with the
3410 new filename format. The affected file silc/client_ops.c.
3412 * Implemented the Cipher API for the rest of the ciphers that
3413 did not implement it or implemented it the wrong way.
3415 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3417 * Register default ciphers and stuff when using the -S option
3418 in the client. Affected file silc/silc.c. Same also when
3419 creating new key pair with -C option.
3421 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Fixed the silc_verify_public_key client operation function to
3424 save the public keys differently. The fingerprint is now
3425 used as filename and not the hostname. This way also the
3426 client keys are saved uniquely and not with hostnames. The
3427 affected file is silc/client_ops.c.
3429 * Trimmed the silc_hash_fingerprint function to remove extra
3430 whitespaces from the end of the fingerprint. The affected
3431 file is lib/silccrypt/silchash.c.
3435 * Added silc_cipher_register_default function to register all
3436 default ciphers. It can be used when configuration files
3437 does not exist and the application does not want any specific
3438 ciphers in any specific order.
3440 The SilcDList is now used as silc_cipher_list dynamically
3441 allocated cipher list. Removed the static list all together
3442 and now all ciphers must be allocated to the dynamic list.
3443 The silc_cipher_alloc routine was changed to check only the
3446 All silc_cipher_* routines that used to return int returns
3449 The affected files lib/silccrypt/silccrypt.[ch].
3451 * The same thing was done to silc_hash_* as for silc_cipher_*
3452 routines. Affected files lib/silccrypt/silchash.[ch].
3454 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3455 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3456 Added also silc_pkcs_[un]register[_default] functions.
3457 Removed the data_context from the PKCS API.
3459 * Added silc_hmac_register_default function to register default
3460 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3461 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3462 to unregister all hmacs at once.
3464 * Register the default ciphers, hash functions, PKCSs and HMACs
3465 if client's configuration file does not exist. The affected
3468 * The client did not load the hash functions from the SIM
3469 modules at all. Added support for this. Affected file is
3470 silc/clientconfig.c.
3472 * When decoding public key with silc_pkcs_public_key_decode, check
3473 the supported algorithm only if PKCS are registered. Affected
3474 file lib/silccrypt/silcpkcs.c. The same was done with the
3475 silc_pkcs_private_key_decode.
3477 * Fixed the SILC List routines to keep the list always in order.
3478 It used to change the list's order when traversing the list but
3479 not it preserves the order. Affected file lib/trq/silclist.h.
3481 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Added the client library to use the SilcSocketConnection's
3484 reference counter (by silc_socket_dup) to prevent the bug that
3485 the socket object may be freed underneath async operation.
3487 * The name resolv library checking fixes in the configure.in.pre.
3490 * Created new version of the protocol drafts for future
3491 development. The -03 drafts are the ones that will be changed
3492 in the trunk now and the -02 will remain as they are.
3494 * Send list of CUMODE notifys to the router when announcing
3495 the channel users to the router. Affected file silcd/server.c.
3496 If the router receiving channel founder CUMODE for a channel
3497 that already has channel founder it will send CUMODE notify
3498 to the sender to remove the channel founder rights from the
3499 announced client. Affected file silcd/packet_receive.c.
3501 * The CUMODE notify may now use Server ID as well as the entity
3502 who changes the mode. Updated protocool specs.
3504 * Updated INSTALL and README files.
3506 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * New web pages in the http://silc.pspt.fi. The pages was
3513 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3515 * Implemented the [DenyConnectin] config section in the server.
3516 Added silc_server_config_denied_conn to check whether incoming
3517 connection is denied. Affected file silcd/serverconfig.[ch].
3519 * Do not check the ports when checking the incoming configuration
3520 data if the port is 0, meaning any. Affected file is
3521 silcd/serverconfig.c.
3523 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Fixed buffer overflow in silc_string_compare in the file
3526 lib/silcutil/silcutil.c.
3528 * Fixed double free in silc_server_command_leave in the file
3531 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3533 * Fixed the version checking in the server. Affected file is
3536 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Fixed the configuration data fetching when accepting new
3539 connections in the server. Affected file silcd/server.c.
3541 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Added `sender_entry' argument to the function
3544 silc_server_packet_relay_to_channel so that we can check
3545 whether some destination actually belongs to the same route
3546 the sender belongs (ie, we must not resend the packet to the
3547 sender). Affected file silcd/packet_send.[ch].
3549 * Added `servername' field to the SilcClientEntry in the server
3550 to hold the name of the server where client is from. Affected
3551 file is silcd/idlist.h.
3553 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Moved the channel message encrypting in the router betwen
3556 router connections from silc_server_channel_message to the
3557 silc_server_packet_relay_to_channel since we want to check
3558 whether we have anybody channel before encrypting anything.
3559 Affected files silcd/packet_[receive/send].c.
3561 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Fixed the [AdminConnection] server config section to support
3564 multiple entries. Affected file silcd/serverconfig.c.
3566 * Added support into the server to check the validity of the
3567 incoming connection before executing any KE or authentication
3570 * The connection configuration is now saved to the KE and
3571 connection auth protocol contexts and not fetched anymore in
3572 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3574 * The local hosts listenning address and port is also resolved
3575 now when starting the server. We want to have the socket object
3576 to include the real address and port for the listener. Added
3577 new function silc_net_check_local_by_sock into the files
3578 lib/silcutil/silcnet.[ch].
3580 * Fixed a broadcast bug in server -> do not broadcast if we
3583 * Fixed a routing bug. Do not route broadcast packets ever.
3584 Broadcast packets must be processed always and not routed since
3585 they may be destined to some other host than yourself and thus
3586 would get routed without no good reason. Affected file is
3589 * Added function silc_server_config_is_primary_route to check
3590 whether primary router connection has been configured (a router
3591 configuration that we are initiating). If there is not, we
3592 will assume that there is only two routers in the SILC network
3593 and we will use the incoming router connection as our primary
3594 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3596 * Changed the order of the broadcasting. Broadcast _after_ the
3597 packet has been processed not before. Affected file is
3600 * Fixed a [ClientConnection] parsing bug. The port was never
3601 parsed correctly thus resulting to port 0. Affected file
3602 silcd/serverconfig.c.
3604 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3605 argument and did not set the broadcast packet flag. Affected
3606 file silcd/packet_send.c. Fixed same bug in the function
3607 silc_server_send_notify as well.
3609 * If we receive NEW_ID packet for our own ID in the server, ignore
3612 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Removed the nickname from the Private Message Payload.
3617 Updated the code and the protocol specs.
3619 * Updated protocol specs for submitting to the IETF.
3621 * Tweaked the Random Number Generator a bit. Affected file
3622 lib/silccrypt/silcrng.c. Exported a new function
3623 silc_rng_[global]_add_noise which can be used to add more
3626 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3628 * Do not parse packets with different timeout when protocol
3629 is active -> may cause problem with rekey. Affected file
3632 * When server receives signoff notify it must not create
3633 new channel key if the client is on any channels since the
3634 sender of the signoff notify will create it.
3636 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added printing of error messages during SKE protocol from the
3639 failure packet sent by server during SKE. Affected file
3642 * Removed the client's failure_callback handling with timeout
3643 and handle it immediately when received.
3645 * The SKE library returned wrong type in SUCCESS and FAILURE
3646 packets. They must be 32 bit MSB not 16 bit MSB.
3648 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Ok, rewrote the logic of the re-key and now it seems to work.
3651 I tested it on high traffic with frequent re-keys without
3652 problems. Added hmac_receive (and renamed hmac to hmac_send)
3653 in SilcClientConnection in lib/silcclient/client.h and
3654 in SilcIDListData in silcd/idlist.h. Also, removed the
3655 SilcPacketParserContext's cipher and hmac fields as they are
3656 not needed anymore and actually caused some problems when
3657 the ciphers and hmac's changed underneath the packet parser.
3659 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * If re-key protocol is active then process the incoming packets
3662 synchronously since we must assure that icoming packets encrypted
3663 with the old key is processed before the new keys is set to
3664 use. This is true other packets than for REKEY packets.
3665 Affected file silcd/server.c. The same was done to client library
3666 as well, affected file lib/silcclient/client.c.
3668 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * Fixed bug in client and server to accept the force send if
3671 the packet is send from silc_[server/client]_packet_process
3672 function. Otherwise the packets are never delivered, oops.
3674 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Disable force sending of packets when REKEY protocol is active.
3677 We must assure that no packet is sent directly when rekey is
3678 performed. All packets must be sent through packet queue.
3679 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3680 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3681 function is silc_[server/client]_packet_send_real to check
3684 * Replaced the SIM paths from example config files to
3685 /usr/local/modules. Also, make install creates now
3686 /usr/local/silc/logs directory to hold all the SILC server
3689 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Made the configure.in.pre work on Solaris. Patch by salo.
3693 * Made all ciphers compatible with non-x86 machines. Defined
3694 CBC mode macros into lib/silccrypt/ciphers_def.h.
3696 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Fixed the make install.
3700 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * When MAC computation fails the silc_packet_decrypt returned 0
3703 even though it was supposed to return -1. Fixed this. The
3704 affected file is lib/silccore/silcpacket.c.
3706 * Do not replace the config files in /etc/silc (in make install)
3707 if they already exist. Affected file ./Makefile.am.
3709 * Do not send re-key packets immediately but through packet queue.
3710 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3712 * Changed silc_net_check_host_by_sock to return FALSE if the
3713 IP/DNS could not be resolved. Though, it returns the IP address
3714 now even if it could not resolve it (but returns also FALSE).
3715 Affected file lib/silcutil/silcnet.[ch].
3717 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Added silc_pkcs_decode_identifier to decode the public key's
3720 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3721 Added also silc_pkcs_free_identifier. Added also new context
3722 SilcPublicKeyIdentifier.
3724 * Added -S option to the silc client. It is used to dump the
3725 contents of the specified public key file.
3727 * Changed the PKCS api to return the public key length when
3728 setting the public key.
3730 * Fixed a fatal bug in the public and private key file loading.
3731 Affected file lib/silccrypt/silcpkcs.c.
3733 * Execute the packet parsing for client with zero (0) timeout
3734 if the protocol is active. Affected file silcd/server.c.
3736 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Made the key generation options to the silcd program. Added
3739 -C option, equivalent to client's option.
3741 * Added new [ServerKeys] config section to the server. It
3742 configures the server's public and private key.
3744 * Defined generic Public Key Payload into the protocol
3745 specification to send specific type of public keys and
3748 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3749 public key or certificate.
3751 * Implemented the GETKEY command to the server and to the
3752 client library and on user interface.
3754 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Made preliminary `make install' work.
3758 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Added SilcServerRekey context into silcd/idlist.h.
3762 * Added the PFS support as defined in the specification to the
3763 SKE protocol. Affected files lib/silcske/*.c.
3765 * Added `ske_group' field to the SilcServerRekey context to hold
3766 the number of the SKE group that is used with PFS in re-key.
3767 Affected file silcd/idlist.h.
3769 * Added PFS re-key support to the server. Affected file is
3772 * Added silc_protocol_cancel to cancel execution of the next
3773 state of the protocol. Affected file is
3774 lib/silccore/silcprotocol.[ch].
3776 * Added the re-key support with and without PFS to the client
3777 library. Re-key is performed once in an hour, by default.
3779 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3780 Added silc_client_rekey_callback and silc_client_rekey_final.
3781 Affected files are lib/silcclient/protocol.[ch] and
3782 lib/silcclient/client.[ch].
3784 * Removed the `hmac_key' and `hmac_key_len' fields from the
3785 SilcClientConnection structure; not needed. Affected file is
3786 lib/silcclient/client.h.
3790 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Do not ask whether user wants to use the negotiated private key
3793 for private messages, just use it. Affected file is
3794 silc/local_command.c.
3796 * Added `send_enc_key' and `enc_key_len' fields to the
3797 SilcIDListData structure since they are needed in the re-key
3798 phase. Affected file is silcd/idlist.[ch].
3800 * Implemented the simple re-key protocol into the server.
3801 Affected files silcd/server.c and silcd/protocol.[ch]. The
3802 re-key will be performed once in an hour, by default.
3804 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3805 Added silc_server_rekey, silc_server_rekey_callback and
3806 silc_server_rekey_final.
3808 * Removed Tunneled flag from the protocol. Updated the code
3809 and the specifications.
3811 * Adde `pfs' field to the SilcIDListData to indicate whether
3812 the PFS is to be performed in the re-key. Affected file is
3815 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3817 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3818 int64 of at least the xintXX size. If void * is less that 4
3819 bytes uint32 * will be used. Defined bool as boolean.
3821 * Changed _ALL_ unsigned long and unsigned int to uint32,
3822 unsgined short to uint16 in the source tree.
3824 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3825 not handle clients that has entry->data.registered == FALSE.
3826 They are not in the network anymore. Affected file is
3829 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Implemented the sending of the SERVER_SIGNOFF notify in the
3832 server. Affected file is silcd/server.c.
3834 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3835 Added also silc_notify_payload_encode_args into the
3836 lib/silccore/silcnotify.[ch].
3838 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3839 Affected file silcd/packet_receive.c.
3841 * Implemented the SERVER_SIGNOFF notify handling in the client
3842 library. Affected file lib/silcclient/client_notify.c. Also,
3843 implemnted the printing of the SERVER_SIGNOFF info to the
3844 application. Affected file silc/client_ops.c.
3846 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3847 if the deleting was successful. Affected file silcd/idlist.[ch].
3849 * Added support for public key authentication in the connection
3850 authentication protocol in the client library. Affected file
3851 lib/silcclient/protocol.c.
3853 * Changed the server's silc_idlist_get_clients_by_* interface
3854 to support already allocated array so that new entries may be
3855 added to pre-allocated array. Affected file silcd/idlist.[ch].
3856 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3857 and command replies.
3859 * All command reply functions in the server now calls the
3860 pending command callback even if error occured. This way the
3861 error will be delivered to the client as well. Affected files
3862 silcd/command.c and silcd/command_reply.c.
3864 * Fixed INFO command to return local server's info if no server
3865 was provided. Affected file lib/silcclient/command.c.
3867 * Removed RESTART command for good. Updated the code and the
3870 * Rewrote parts of the task system. It is a bit simpler now.
3871 Removed unsued task priorities. The affected files are
3872 lib/silcutil/silctask.[ch].
3874 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Moved the USERS printing from the library to the application.
3877 Affected files lib/silcclient/command.c and silc/client_ops.c.
3879 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Added channel key re-key support. The re-key is perfomed
3884 only by the router and is done once in an hour. Added `rekey'
3885 field to the SilcChannelEntry in the server. Affected files
3886 silcd/server.c and silcd/idlist.h.
3888 * Added silc_task_unregister_by_context into the file
3889 lib/silcutil/silctask.[ch].
3891 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3893 * Added SILC_UMODE_GONE mode to indicate when the client is not
3894 present in the SILC network. Added also support to the local
3895 command AWAY that will set this mode. Added support of showing
3896 "xxx is gone" in WHOIS command. The USERS command shows the
3897 gone status as well.
3899 * Fixed setting server and router operator privileges in the
3900 server's UMODE command. Affected file silcd/command.c.
3902 * Merged the SKE KE1 and KE2 payloads into one payload. The
3903 new KE payload is equivalent to the old KE2 payload.
3905 Cleaned up the SKE Start Payload parsing. It now uses the
3906 simple buffer unformatting to do the parsing. A lot faster
3909 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3910 to the SKE that is used to indicate whether both of the SKE
3911 parties should perform authentication. By default only the
3912 responder performs authentication. By setting this flag also
3913 the initiator must do authentication. By default it is unset
3914 since in normal SKE case, client to server connection, only
3915 the responder should do authentication. When doing SKE between
3916 two clients both should perform authentication. Updated the
3917 code and the protocol specs.
3919 * A little fix to IDENTIFY command in the server. Search the
3920 client first by hash not nickname. Affected file is
3923 * Fixed the silc_client_close_connection to support closing
3924 the client to client connections wihtout deleting too much
3925 data. Affected file lib/silcclient/client.c.
3927 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3928 are received if protocol used to be active but is not anymore
3929 the application would crash due to NULL pointer dereference.
3930 Affected files silcd/server.c and lib/silcclient/client.c.
3932 * Added `hash' field to the SilcClientConnection to include
3933 the hash function negotiated in the SKE protocol.
3935 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3936 to set the channel founder authentication data. A client can
3937 claim the founder rights later by providing the authentication
3938 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3939 This way the channel founder can regain the channel founder
3940 privileges even it is left the channel. This works only on
3941 local server and the client must be connected to the same
3942 server to be able to regain the founder rights. Updated the
3943 protocol specs accordingly.
3945 Added support to the CMODE command in the client to set the
3946 founder auth data. Read the README to see how to set it.
3948 Added support to the CUMODE command to claim the founder
3949 rights. Read the README to see how to do it.
3951 Added support for the founder authentication to the Channel
3952 Entry in the server. Affected file silcd/idlist.h.
3954 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3955 server's CMODE command. Affected file silcd/command.c.
3957 * Added the following new functions into lib/silccore/silcauth.[ch]:
3958 silc_auth_get_method and silc_auth_get_data.
3960 * The server now saves the remote hosts public key to the
3961 SilcIDListData pointer. Affected file silcd/protocol.c.
3963 * The normal server now does not remove the channel entry from
3964 the cache if the founder authentication data is set. It used
3965 to remove it if the founder was the last one on the channel on
3966 the server and left the channel. The auth data is saved and
3967 if the channel is re-joined later the old entry is used with
3968 the old auth data. Affected files silcd/command_reply.c and
3971 * Removed the `pkcs' field from the SilcIDListData structure
3972 in the server; it is not used. Affected file silcd/idlist.h.
3974 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Fixed packet processing on slow links. Partial packets were
3977 never re-processed because the incoming data buffer was cleared
3978 by the application. Application must not directly clear the
3979 sock->inbuf, the packet processing routines handle it. Fixed
3980 this in client library and in server.
3982 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3984 * Fixed the WHOIS and IDENTIFY send reply function to really
3985 check whether to send list or just one entry. Affected file
3988 * Cleaned up the LEAVE command's channel key distribution. The
3989 affected file silcd/command.c.
3991 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3992 can enforce the channel mode as well. In that case the ID
3993 includes the ID of the server. The code now enforces the
3994 mode change if the router have different mode than the server.
3996 * The notify client operation with CMODE_CHANGE notify can now
3997 return NULL client_entry pointer if the CMODE was not changed
3998 by client. Application must check for this.
4000 * Added <Server ID> argument to INFO command to support server
4001 info fetching by Server ID.
4003 * Added silc_server_announce_get_channel_users to get assembled
4004 packets of channel users of the specified channel. Affected
4005 file silcd/server.[ch].
4007 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4008 was freed underneath the ID Cache.
4010 * Re-announce clients when the server received CHANNEL_CHANGE
4011 notify from the router. Affected file silcd/packet_send.c.
4013 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4016 crashed since it did not handle the fact that there is no cipher
4017 called "3" and didn't check the error condition. Now fixed.
4019 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4020 flag. It can be used to send message requests.
4022 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Implemented the RESTART command in the client.
4026 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4027 notice type messages. Added notice printing to the user
4030 * The channel keys are not re-generated if the channel's mode
4031 is PRIVKEY, ie private key on the channel exists. Affected
4032 files silcd/server.c and silcd/command.c.
4034 * Fixed a little bug in channel message delivery when channel
4035 private keys are set in the server. Affected file is
4036 silcd/packet_send.c.
4038 * Changed the setting on channel->on_channel = TRUE from the
4039 silc_client_save_channel_key to the JOIN command reply. The
4040 key payload is not received if the private channel key is set.
4041 Affected file lib/silcclient/command_reply.c and the
4042 lib/silcclient/client_channel.c.
4044 * When the CMODE_CHANGE notify is sent and the channel private
4045 key mode is removed the channel key must be re-generated in
4046 other cells as well. Added this support for the router in the
4047 silcd/packet_receive.c.
4049 * Added new local command NOTICE to send notice message on
4050 channel. Affected file silc/local_command.[ch].
4052 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Added new local command ME to the client. It is used to send
4055 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4056 some action. Affected file silc/local_command.[ch].
4058 * Changed channel_message and private_message client operations
4059 to deliver the message flags to the application. Added also
4060 the `flags' arguments to the silc_client_send_channel_message
4061 and silc_client_send_private_message functions. Affected file
4064 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Redefined the Private Message Payload to support private message
4067 keys and to support the new private message flags. Updated
4068 the protocol specs. Flags makes it possible to have for example
4069 CTCP style messages.
4071 * Added new type SilcPrivateMessagePayload and defined an API
4072 for it in the lib/silcclient/silcprivate.[ch].
4074 * Tested private message private keys successfully. Tested the
4075 private message key set, unset and list commands with the new
4078 * Redefined the Channel Message Payload to include the channel
4079 message flags (equal with private message flags) to support
4080 for example CTCP style messages.
4082 * Defined some of the message (for channel and private message)
4083 flags. Updated the protocol specs and added the flags to the
4084 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4086 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * Added SilcKeyAgreementStatus type to the key agreement routines
4089 to indicate the current status and error if one occured.
4090 The status types are defined in the lib/silcclient/silcapi.h.
4092 * Added new local command KEY that is used to set and unset private
4093 keys for channels, set and unset private keys for private messages
4094 with remote clients and to send key agreement requests and
4095 negotiate the key agreement protocol with remote client. The
4096 key agreement is supported only to negotiate private message keys,
4097 it currently cannot be used to negotiate private keys for channels,
4098 as it is not convenient for that purpose.
4100 * Fixed a minor pending callback setting bug in the function
4101 silc_client_get_client_by_id_resolve, now the function works.
4102 Affected file lib/silcclient/idlist.c.
4104 * Added function silc_net_get_local_port to get local bound
4105 port by socket. Added to lib/silcutil/silcnet.[ch].
4107 * Added `sockets' and `sockets_count' fields to the SilcClient
4108 object. They hold the sockets of the listenning sockets in
4109 the client. Listenning sockets may be for example the key
4110 agreement server. Affected file lib/silcclient/client.[ch].
4111 Added functions the silc_client_add_socket and the
4112 silc_client_del_socket. They are exported to the application
4115 * Added ~./silc/clientkeys to support other client's public keys.
4117 * Renamed verify_server_key client operation to verify_public_key
4118 and added one argument to indicate the type of the connection
4119 (server, client etc.).
4121 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Added silc_server_connection_auth_request to handle the
4124 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4125 silcd/packet_receive.[ch].
4127 * Added silc_server_send_connection_auth_request into the
4128 silcd/packet_send.c to send the connection auth request packet.
4130 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4133 * Fixed the public key authentication in responder side in the
4134 server. The `auth_data' pointer includes the SilcPublicKey
4135 not the path to the public key. Affected file silcd/protocol.c.
4137 * Implemented the public key authentication in the initiator side
4138 in the server. Affected file silcd/protocol.c.
4140 * Removed the [RedirectClient] config section from the server
4141 configuration. Is not needed and I don't want to implement it.
4143 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Cleaned up the CMODE command in the server. It now works
4146 correctly and supports all the modes defined in the protocol.
4147 Affected file is silcd/command.c.
4149 * Added `hmac_name' field to the SilcChannelEntry in the server
4150 to hold the default HMAC of the channel. It can be set when
4151 creating the channel (with JOIN command). Affected files
4154 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4155 type to indicate the change of the current cipher and hmac
4156 on the channel. Client can safely ignore the <cipher> argument
4157 (if it chooses to do so) since the CHANNEL_KEY packet will
4158 force the channel key change anyway. The <hmac> argument is
4159 important since the client is responsible of setting the new
4160 HMAC and the hmac key into use.
4162 * Fixed the CMODE command in the client library as well.
4164 * Tested CMODE command in router environment successfully.
4166 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Show the version of the remote client (or server) when connecting
4169 to the server. It is logged to the log file. Affected file
4170 is silcd/protocol.c.
4172 * Fixed the KILLED notify handling in the client library. The
4173 client must be removed from all channels when receiving the
4176 Also, do not remove the client entry when giving the KILL
4177 command but when the KILLED notify is received.
4179 * Removed silc_idlist_find_client_by_nickname from the server.
4180 Not needed anymore. Affected files silcd/idlist.[ch].
4182 * Implemented the CHANNEL_CHANGE notify type handling to the
4183 server. Affected file silcd/server.c.
4187 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Added silc_server_send_notify_invite to send the INVITE
4190 notify between routers.
4192 * Implemented the INVITE command correctly to the server.
4194 * Implemented the INVITE notify type handling in the server.
4196 * Implemented the INVITE command to the client library and on the
4199 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4201 * Added function silc_server_get_client_resolve to find the
4202 client entry by ID from all ID lists and then resolve it
4203 (using WHOIS) if it cannot be found. Affected file is
4206 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Implemented the BAN command to the client library.
4210 * The JOIN command in the server now checks the invite list
4213 * Changed the silc_command_reply_payload_encode_va and the
4214 silc_command_payload_encode_va to support that if argument is
4215 NULL it ignores and checks the next argument. Affected file
4216 lib/silccore/silccommand.c.
4218 * Added silc_server_send_notify_ban to send the BAN notify
4219 type between routers.
4221 * Chaned the silc_notify_payload_encode to support that if
4222 argument is NULL it ignores and checks the next argument.
4223 Affected file lib/silccore/silcnotify.c.
4225 * Tested ban lists in router environment successfully.
4227 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Implemented BAN command to the server, in silcd/command.[ch].
4231 * Removed the BAN and INVITE_LIST modes from the CMODE command
4234 * Added function silc_string_match to regex match two strings.
4235 Affected files lib/silcutil/silcutil.[ch].
4237 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Redefined parts of the SilcChannelEntry in the server to support
4240 the new ban and invite lists.
4242 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Redefined the INVITE command. The same command can be used to
4245 invite individuals to the channel but also to manage the invite
4246 list of the channel (to add to and remove from the invite list).
4247 Updated the protocol specs.
4249 * Added new command SILC_COMMAND_BAN that can be used to manage
4250 the ban list of the channel. Updated the protocol specs.
4252 * Removed the channel modes: the SILC_CMODE_BAN and the
4253 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4254 in the CMODE command. The equivalent features are now available
4255 using INVITE and BAN commands. Updated the protocol specs.
4257 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4258 in the network about change in the current ban list. The notify
4259 type is not used by the client.
4261 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4262 support the invite lists.
4264 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Added new function silc_string_regexify that converts string
4267 including wildcard characters into regex string that can
4268 be used by the GNU regex library. Added into the file
4269 lib/silcutil/silcutil.[ch].
4271 Added silc_string_regex_combine to combine to regex strings
4272 into one so that they can be used as one regex string by
4273 the GNU regex library. Added into the file
4274 lib/silcutil/silcutil.[ch].
4276 Added silc_string_regex_match to match two strings. It returns
4277 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4279 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4281 * Imported GNU regex to the soruce tree into lib/contrib.
4282 Fixed some compiler warning from the regex.c.
4284 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Fixed MOTD command in the server to work in router environment.
4288 * Fixed the MOTD command in the client library to support
4289 the server argument in the command.
4291 * Added `nickname_len' argument to the silc_idlist_add_client
4292 in the server, as the `nickname' argument may be binary data
4295 * Added silc_idlist_get_channels to return all channels from
4298 * Implemented LIST command to the server. Affected file is
4301 * Implemented the LIST command to the client library and on the
4304 * Added [<user count>] argument to the LIST command reply.
4305 With private channels the user count is not shown.
4307 * Updated TODO and README.
4309 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * The client entry's data.registered must be TRUE even with
4312 global client entry on global client list. The data.registered
4313 is used to check whether the client is anymore in the network,
4314 for example with WHOWAS command so it must be valid.
4316 * Fixed the WHOWAS command in the server. It now actually works
4317 in router environment. Added function into silcd/command_reply.c
4318 silc_server_command_reply_whowas_save.
4320 * Added silc_idlist_purge function to the silcd/idlist.c
4321 to periodically purge the ID Cache.
4323 * Fixed INFO command in the server. It works now in router
4324 environment. Added <server name> argument to the INFO command
4325 reply. Updated the protocol specs.
4327 * Fixed minor bug in silc_idcache_purge to not purge if the
4328 expire value is zero.
4330 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4331 they were buggy because of the WHOWAS information.
4333 * Fixed local command MSG to handle the async resolving of
4334 the remote client properly. It used to fail the first MSG.
4335 Affected file silc/local_command.c.
4337 * Added `data_len' field to SilcIDCache context.
4339 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Update TODO. Todo in commands in the server.
4343 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4346 used by routers as broadcast packet to inform other routers
4347 about the changed user mode.
4349 Implemented the notify handling in the server. Affected file is
4350 silcd/packet_receive.c. Added the function
4351 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4353 * Added new generic Channel Payload and deprecated the New Channel
4354 Payload. The New Channel Payload is now the generic Channel
4357 * Added new argument `mode' to the silc_server_send_new_channel
4358 as it is required in the Channel Payload now.
4360 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4361 and created a new and real SilChannelPayload to represent the
4362 new generic Channel Payload. Implemented the encode/decode
4363 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4365 * Added silc_server_get_client_channel_list to return the list
4366 of channels the client has joined for WHOIS command reply.
4367 Affected file silcd/server.[ch].
4369 * Implemented the channel list sending in the WHOIS command reply
4370 in server and in the client.
4372 Implemented the channel list displaying on the user interface
4373 as well. Affected file silc/client_ops.c.
4375 * Added silc_channel_payload_parse_list to parse list of Channel
4376 Payloads. It returns SilcDList list of SilcChannelPayloads.
4377 Client for example can use this function to parse the list of
4378 channels it receives in the WHOIS command reply. The caller
4379 must free the list by calling silc_channel_payload_list_free.
4380 Affected files lib/silccore/silcchannel.[ch].
4382 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Added one new argument <user mode> to the WHOIS command reply
4385 to return the mode of the user in SILC. Updated the protocol
4388 Implemented it to the server and client.
4390 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Fixed the mode printing on the user interface on joining.
4393 Affected file silc/client_ops.c.
4395 * Implemented the UMODE command and user modes in general to the
4396 client library and to the user interface.
4398 * Implemented the UMODE command to the server.
4400 * The server now sends UNKNOWN_COMMAND error status if client sends
4401 unknown command. Affected file silcd/command.c.
4403 * All server commands now handle the command identifier the right
4404 way when sending the command reply to the client. The client can
4405 use to identify the command replies with the identifier.
4407 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Added silc_server_get_client_route to resolve the route to
4410 the client indicated by the client ID. Affected file is
4413 * Added silc_server_relay_packet as general function to relay
4414 packet to arbitrary destination. This deprecates functions
4415 like _send_private_message_key, _relay_notify etc. Affected
4416 file is silcd/packet_send.[ch].
4418 Removed silc_server_send_key_agreement,
4419 silc_server_send_private_message_key and
4420 silc_server_packet_relay_notify functions from the file
4421 silcd/packet_send.[ch].
4425 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4426 server. Affected file silcd/packet_receive.[ch].
4428 * Implemented the KILL command to the client. Implemented the
4429 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4430 Affected files lib/silcclient/command[_reply].c and
4431 lib/silcclient/client_notify.c. Implemented the KILL notify
4432 printing in the user inteface.
4434 * Fixed a lot silc_parse_nick memory leaks from the client
4435 library in the file lib/silcclient/command.c.
4437 * Changed the silc_server_send_notify_on_channels's `sender'
4438 argument from SilcSocketConnection to SilcClientEntry to
4439 check the sender as entry and not as connection object and not
4440 to send to the client provided as argument. The affected file
4441 is silcd/packet_send.[ch].
4443 * The notify packets that are destined directly to the client used
4444 to not to be processed by the server. Now changed that and the
4445 server processes all notify packets. After relaying the packet
4446 to the client the notify packet is processed in the server.
4448 * The silc_server_free_client_data now checks whether there is
4449 pending outgoing traffic for the client and purges the data to
4450 the network before removing the client entry.
4452 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4455 an client is killed from the SILC Network. Updated the protocol
4458 Added new function silc_server_send_notify_killed to the
4459 silcd/packet_send.[ch].
4461 * Added function silc_server_packet_relay_notify to relay notify
4462 packets that are destined directly to a client. In this case
4463 the server does not process the notify packets but merely relays
4464 it to the client. Affected file silcd/packet_send.[ch].
4466 Added also silc_server_packet_process_relay_notify to check
4467 whereto relay the notify. Affected file is
4468 silcd/packet_receive.[ch].
4470 * Implemented the KILL command to the server.
4474 * Added the backup schema desgined last fall to the protocol
4475 specs for everyone to see. The specification is in the
4476 *-spec-xx.txt draft and the packet type definitions for the
4477 backup routers is in *-pp-xx.txt draft. Thusly, added also
4478 new packet type SILC_PACKET_CELL_ROUTERS.
4480 * A big security problem in the implementation discovered. The
4481 signoff of an client did not cause new channel key generation
4482 which it of course should've done. The channel keys must be
4483 always re-generated when client leaves (or signoffs) the channel.
4484 The silc_server_remove_from_channels funtion now handles
4485 the channel key re-generation.
4487 * Added `sender' argument to the silc_server_send_notify_on_channels
4488 to not to send the client provided as argument. Affected file
4489 silcd/packet_send.[ch].
4491 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Implemented OPER and SILCOPER commands into the server and
4496 * Added silc_auth_verify and silc_auth_verify_data to verify
4497 the authentication directly from the authentication payload.
4498 It supports verifying both passphrase and public key based
4499 authentication. Affected file lib/silccore/silcauth.[ch].
4501 * Added `hash' field to the SilcIDListData structure. It is the
4502 hash negotiated in the SKE protocol. Affected file is
4505 * Slight redesigning of the SilcAuthPayload handling routines.
4506 Do not send SilcPKCS but SilcPublicKey as argument.
4508 * Implemented the public key authentication support to the
4509 serverconfig. The public key is loaded from the provided path
4510 and saved as authentication data to void * pointer. Thus,
4511 changed the unsigned char *auth_data to void *auth_data;
4513 * Fixed SHUTDOWN command to send the reply before the server
4514 is shutdown. :) Affected file silcd/command.c.
4516 * Fixed fatal bug in CONNECT command. The hostname was invalid
4517 memory and server crashed. Affected file silcd/command.c.
4519 * Fixed fatal bug in CLOSE command. The server_entry became
4520 invalid but was referenced later in the command. Affected file
4523 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Fixed fatal bug in failure packet handling. Server ignored
4526 the failure and thus crashed when it came.
4530 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4533 that the command may be executed only once in (about) 2 seconds.
4534 The old SILC_CF_LAG flag is same but allows command bursts up
4535 to five before limiting.
4537 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4538 server code. Various commands now includes the CF_LAG_STRICT
4539 flag to disallow any kind of miss-use of the command.
4541 * Fixed the silc_buffer_unformat to not to allocate any data
4542 if the length of the data is zero. It used to allocate the
4543 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4545 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Changed the format of AdminConnection configuration section
4548 in the server. Added username of the admin to the format.
4549 Affected files silcd/serverconfig.[ch].
4551 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4552 to return admin configuration data by host, username and/or
4555 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Implemented WHOWAS command to the server. Added the functions:
4559 silc_server_command_whowas_parse,
4560 silc_server_command_whowas_send_reply,
4561 silc_server_command_whowas_from_client and
4562 silc_server_command_whowas_from_server
4564 * Added <Client ID> argument to the WHOWAS command reply. Updated
4565 the protocol specs accordingly.
4567 * Implemented WHOWAS command and command_reply to the client
4570 Implemented the WHOWAS printing on the user interface.
4572 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4574 * Added new argument to the WHOWAS command reply, the real name.
4575 It is an optional argument. Updated the protocol specs.
4577 * Added SilcIDCacheDestructor callback that is registered when
4578 the SilcIDCache is allocated. The callback is called when
4579 an cache entry in the ID Cache expires, or is purged from the
4580 cache. Added into lib/silccore/idcache.[ch].
4582 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4583 to destruct the client entries when the cache entry expires.
4584 Other ID Cache's in server and in the client library ignores
4587 * If the ID Cache entry's `expire' field is zero then the entry
4588 never expires. Added boolean `expire' argument to the
4589 silc_idcache_add function in the lib/silccore/idcache.[ch].
4590 If it is TRUE the default expiry value is used.
4592 * Added silc_server_free_client_data_timeout that is registered
4593 when client disconnects. By default for 5 minutes we preserve
4594 the client entry for history - for WHOWAS command.
4596 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4598 * Added support to the server to enforce that commands are not
4599 executed more than once in 2 seconds. If server receives
4600 commands from client more frequently, timeout is registered
4601 to process the commands. Affected file silcd/command.c.
4602 Added new function silc_server_command_process_timeout.
4604 * Changed NICK_NOTIFY handling in client library to check that
4605 if the client's nickname was changed, so there is no need to
4606 resolve anything from the server.
4608 * Removed error printing from the WHOIS and IDENTIFY commands.
4609 If error occurs then it is ignored silently in the client library.
4610 The application, however, may map the received error to
4611 human readable error string. The application currently maps
4612 the NO_SUCH_NICKNAME error to string.
4614 * Made the command status message public to the application. Moved
4615 them from lib/silcclient/command_reply.c to
4616 lib/silcclient/command_reply.h. The application can map the
4617 received command status to the string with the
4618 silc_client_command_status_message function.
4620 * Added check to the server to check that client's ID is same
4621 as the Source ID in the packet the client sent. They must
4624 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4626 * Added dist-bzip hook to the Makefile.am to make bzip2
4627 compressed distributions.
4629 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Server now enforces the maximum length for the nickname and
4632 the channel as protocol specification dictates. 128 bytes for
4633 nickname and 256 bytes for channel name.
4635 * Moved the WHOIS printing to the application. The client libary
4636 does not print out the WHOIS information anymore, the application
4637 must do it. Renamed silc_client_command_reply_whois_print to
4638 the silc_client_command_reply_whois_save.
4640 The client's idle time is also sent to the application now, and
4641 the idle is shown on screen.
4643 * Added silc_client_command_reply_identify_save to save the
4644 received IDENTIFY entries.
4646 * Do not check for channel private keys in message sending and
4647 reception if the channel does not have the PRIVKEY mode set.
4648 Affected file lib/silclient/client_channel.c.
4650 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4653 just surfaced after chaning the JOIN procedure.
4655 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added silc_client_get_clients_by_list to get client entries
4658 from Client ID list, that is returned for example by JOIN
4659 and USERS command replies. The application should use this
4660 function for example when JOIN command reply is received to
4661 resolve the clients already on the channel (library does not
4662 do that anymore as USERS command reply is not used in the JOIN
4663 procedure anymore). Affected files lib/silcclient/silcapi.h and
4664 lib/silcclient/idlist.c.
4666 * JOIN command reply and USERS command reply returns now SilcBuffer
4667 pointers instead of unsigned char pointers when returning
4668 the client list and mode list.
4670 * Added <Client ID> argument to the JOIN command reply, mainly
4671 for the server to identify for which client the command was
4672 originally sent. Updated protocol specs accordingly.
4674 * Added SilcDlist private_key pointer to the SilcChannelEntry
4675 in the client to support the channel private keys. Affected
4676 file is lib/silcclient/idlist.h.
4678 * Added SilcChannelPrivateKey argument to the function
4679 silc_client_send_channel_message so that application can choose
4680 to use specific private ke if it wants to. If it is not provided,
4681 the normal channel key is used, unless private keys are set.
4682 In this case the first (key that was added first) is used
4683 as the encryption key.
4685 * Implemented the support for channel private key handling.
4686 Implemented the following functions:
4688 silc_client_add_channel_private_key,
4689 silc_client_del_channel_private_keys,
4690 silc_client_del_channel_private_key,
4691 silc_client_list_channel_private_keys and
4692 silc_client_free_channel_private_keys
4694 Affected file lib/silcclient/client_channel.c.
4696 * Added the support for the private keys in the channel message
4697 sending and encryption and in the message reception and
4698 decryption. Affected funtions are
4699 silc_client_send_channel_message and silc_client_channel_message.
4701 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4703 * Added SKE's key verify callback to the client library's
4704 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4706 * Removed the statement that server (or router) must send USERS
4707 command reply when joining to the channel so that the client
4708 knows who are on the channel. Instead, the client list and
4709 client's mode list is now sent in the JOIN command reply to the
4710 client who joined channel. This is better solution.
4712 * Added function silc_server_get_users_on_channel and function
4713 silc_server_save_users_on_channel to the silcd/server.[ch].
4715 * Removed function silc_server_command_send_users from the
4718 * Do not show topic on the client library anymore. The topic is
4719 sent in the command reply notify to the application and the
4720 application must show the topic now.
4722 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4724 * Added client searching by nickname hash into the IDENTIFY and
4725 WHOIS commands in the server as they were clearly missing from
4726 them. Affected file is silcd/command.c.
4728 * Fixed a bug in private message receiving in the client library.
4729 The remote ID was freed and it wasn't supposed, now it is
4732 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Minor fix to the channel payload; allocate the data area, as it
4735 needs to be of specific length.
4737 * If the key agreement port is zero then the operating
4738 system will define the bound port. Affected files are
4739 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4741 * Added new function silc_channel_payload_decrypt into the file
4742 lib/silccore/silcchannel.[ch].
4744 * Moved the channel message etc, check from silc_packet_decrypt
4745 to applications. The library calls now a generic
4746 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4747 when the packet is either normal or special. This was done to
4748 allow more wide range of checking that was not allowed when
4749 the code was in library. Now applications can do virtually any
4750 checks to the packet and return to the library the decision how
4751 the packet should be processed. Affected files are
4752 lib/silccore/silcpacket.[ch].
4754 Added silc_server_packet_decrypt_check to the server and
4755 silc_client_packet_decrypt_check to the client library.
4757 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4758 to send with specified source and destination information.
4760 * Channel message delivery between routers was broken after the
4761 channel key distribution was fixed earlier. The channel key
4762 was used be to distributed to other routers as well which is not
4763 allowed by the protocol. Now this is fixed and channel keys
4764 really are cell specific and the channel message delivery between
4765 routers comply with the protocol specification.
4767 * Fixed various commands in server to check also the global list
4768 for the channel entry and not just the local list. The affected
4769 file silcd/command.c.
4771 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Added assert()s to buffer formatting and unformatting routines
4774 to assert (if --enable-debug) when error occurs. Affected
4775 file: lib/silcutil/silcbuffmt.c.
4777 * Changed to auto-reconnect to check whether the remote host is
4778 router and register the re-connect timeout if it is. It used
4779 to check that whether we are normal server, but router must do
4780 auto-reconnect with another router as well. Affected file
4783 * Removed the [<key len>] option from CMODE command as the cipher
4784 name decides the key length, nowadays. See the defined ciphers
4785 from the protocol specification.
4787 * Added [<hmac>] option to the CMODE command to define the HMAC
4788 for the channel. Added SILC_CMODE_HMAC channel mode.
4790 * Added [<hmac>] option for the JOIN command so that user can
4791 select which HMAC is used to compute the MACs of the channel
4794 * Added Hmac field to the Channel Message Payload. The integrity
4795 of plaintext channel messages are now protected by computing
4796 MAC of the message and attaching the MAC to the payload. The
4797 MAC is encrypted. Now, it is clear that this causes some
4798 overhead to the size of the packet but rationale for this is that
4799 now the receiver can verify whether the channel message decrypted
4800 correctly and also when private keys are set for the channel the
4801 receiver can decrypt the packet with several keys and check from
4802 the MAC which key decrypted the message correctly.
4804 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4805 lib/silccrypt/silccipher.[ch].
4807 * Added silc_hash_len to return the digest length into the
4808 lib/silcrypt/silchash.[ch].
4810 * Rewrote parts of Silc Channel Payload interface in the
4811 lib/silccore/silcchannel.[ch]. The encode function now also
4812 encrypts the packet and parse function decrypts it.
4814 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Fixed a minor formatting bug in the SKE's key material processing.
4817 It actually might have processed the keys wrong way resulting
4820 * Redefined the mandatory HMAC algorithms and added new algorithms.
4821 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4822 and hmac-md5 truncated to 96 bits. The mandatory is now
4823 hmac-sha1-96. Rest are optional (including the one that used
4824 to be mandatory). Rationale for this is that the truncated HMAC
4825 length is sufficient from security point of view and can actually
4826 make the attack against the HMAC harder. Also, the truncated
4827 HMAC causes less overhead to the packets. See the RFC2104 for
4830 * Added new [hmac] configuration section. The SKE used to use
4831 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4832 is of course wrong. The official names that must be proposed in
4833 the SKE are the ones defined in the protocol specification
4834 (hmac-sha1-96 for example). The user can configure any hmac
4835 using any hash function configured in the [hash] section. At
4836 least, the mandatory must be configured.
4838 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4840 * Added HMAC list to the SKE proposal list. It has now both
4841 hash algorithm list and HMAC list. This makes the protocol
4842 incompatible with previous versions. The SKE now seems to work
4843 the way it is supposed to work, for the first time actually.
4845 * Defined plain Hash algorithms to the protocol specification.
4848 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Implemented support for key agreement packets into the server.
4851 Added functions silc_server_key_agreement and
4852 silc_server_send_key_agreement. Other than these functions,
4853 server has nothing to do with this packet.
4855 * Added support for private message key packets into the server.
4856 Added functions silc_server_private_message_key and
4857 silc_server_send_private_message_key.
4861 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4862 called in the protocol's final callback instead in the END
4863 protocol state. This makes a little more sense and in the same
4864 time in client we can use the same protocol routines for normal
4865 key exchange and to key agreement packet handling as well.
4867 * Added to both client's and server's KE protocol context the
4868 SilcSKEKeyMaterial pointer to save the key material. We will
4869 bring the key material to the protocol's final callback by doing
4870 this. The final callback must free the key material.
4872 * Added SKE's packet_send callback into client's KE protocol
4873 context so that the caller can choose what packet sending function
4874 is used. This way we can use different packet sending when
4875 doing normal SKE when doing key agreement packet handling (in
4876 the key agreement packet handling we do not want to encrypt
4879 * Implemented the responder side of the key agreement routines
4880 in the client. The client can now bind to specified port and
4881 accept incoming key negotiation. The key material is passed
4882 to the application after the protocol is over.
4884 * Implemented the processing of incoming Key Agreement packet
4885 in the client. Added function silc_client_key_agreement to
4888 * Implemented the intiator side of the key agreement routines
4889 in the client. The client can now initiate key agreement with
4890 another remote client. The key material is passed to the
4891 application after the protocol is over.
4893 * Created client_keyagr.c to include all the key agreement
4896 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4897 SILC_TASK_CALLBACK except that it is not static.
4899 * Created client_notify.c and moved the Notify packet handling
4900 from the client.[ch] into that file.
4902 * Created client_prvmsg.c and moved all private message and
4903 private message key routines from the client.[ch] into that file.
4905 * Create client_channel.c and moved all channel message and
4906 channel private key routines from the client.[ch] into that file.
4908 * Changed silc_client_get_client_by_id_resolve to resolve with
4909 WHOIS command instead of IDENTIFY command, in the file
4910 lib/silclient/idlist.c.
4912 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Implemented the SKE's responder side to the Client library.
4916 * When FAILURE is received to the protocol do not trust it
4917 blindly. Register a timeout to wait whether the remote closes
4918 the connection as it should do it, only after that process the
4919 actual failure. This was changed to both client and server.
4921 * Added client_internal.h to include some of the structures
4922 there instead of client.h in lib/silcclient/.
4924 * Added function silc_task_unregister_by_callback to unregister
4925 timeouts by the callback function.
4927 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Some "Incomplete WHOIS info" errors has been appearing on the
4930 log files. Took away the entry->userinfo check from WHOIS
4931 reply sending. The entry->userinfo is now " " if client did not
4932 provide one. I thought this was fixed earlier but something
4933 is wrong still. Let's see if the error still appears.
4935 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed a minor bug in the login when the channel key is
4938 re-generated in the server. It used to generate the key in
4939 wrong order and thus caused problems in the channel traffic.
4941 * Fixed a minor bug in channel key distsribution after
4942 KICK command. The key was not sent to the router even though
4945 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Added silc_ske_process_key_material_data as generic routine
4948 to process any key material as the SILC protocol dictates. The
4949 function is used by the actual SKE library but can be used by
4950 applications as well. This relates to the private message keys
4951 and the channel private keys since they must be processed the
4952 same way the normal SILC session keys. The protocol dictates
4953 this. Affected files: lib/silcske/silcske.[ch].
4955 Added also silc_ske_free_key_material to free the
4956 SilcSKEKeyMaterial structure.
4958 * Defined silc_cipher_set_key function to set the key for
4959 cipher without using the object's method function. The affected
4960 files: lib/silccrypt/silccipher.[ch].
4962 * Implemented silc silc_client_add_private_message_key,
4963 silc_client_add_private_message_key_ske,
4964 silc_client_del_private_message_key,
4965 silc_client_list_private_message_keys and
4966 silc_client_free_private_message_keys functions in the
4969 Added functions silc_client_send_private_message_key to send
4970 the Private Message Key payload and silc_client_private_message_key
4971 to handle incoming Private Message Key payload.
4973 * Added Cipher field to the Private Message Key payload to set
4974 the cipher to be used. If ignored, the default cipher defined
4975 in the SILC protocol (aes-256-cbc) is used.
4977 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Removed lib/silcclient/ops.h file.
4981 Redefined parts of the SILC Client Library API. Created new
4982 file silcapi.h that deprecates the ops.h file and defines the
4983 published Client Library API. Defined also private message key
4984 API and channel private key API into the file.
4986 This is the file that the application must include from the
4987 SILC Client Library. Other files need not be included by
4988 the application anymore.
4990 * Added new key_agreement client operation callback and also
4991 defined the Key Agreement library API for the application.
4993 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4996 is used by clients to request key negotiation between another
4997 client in the SILC network. If the negotiation is started it
4998 is performed using the SKE protocol. The result of the
4999 negotiation, the secret key material, can be used for example
5000 as private message key.
5002 Implemented the Key Agreement payload into the files
5003 lib/silccore/silauth.[ch].
5005 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Redefined ciphers for the SILC protocol. Added some new ciphers
5008 and defined the key lengths for the algorithms. Changed the
5009 code accordingly. The default key length is now 256 bits.
5011 * Fixed SKE key distribution function silc_ske_process_key_material
5012 when the key length is more than 128 bits. The default key
5013 length in SILC is now 256 bits.
5015 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5016 to indicate unsupported algorithm.
5018 * Renamed rijndael.c to aes.c and all functions as well.
5020 * Fixed a long standing channel key setting bug in client library.
5021 Weird that it has never surfaced before.
5023 * Fixed bug in channel deletion. If the entire channel is removed
5024 then it must also delete the references of the channel entry
5025 from the client's channel list as the client's channel entry and
5026 the channel's client entry share same memory.
5028 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Implemented CONNECT and SHUTDOWN commands in the client.
5032 * Implemented CLOSE command to the client.
5034 * Added the function silc_idlist_find_server_by_name into the
5035 files silcd/idlist.[ch].
5037 Added the function silc_idlist_find_server_by_conn into the
5038 files silcd/idlist.[ch].
5040 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * DIE command was renamed to SHUTDOWN. Updated the both code
5045 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5046 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5048 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5051 * Added function silc_server_create_connection function to create
5052 connection to remote router. My server implementation actually
5053 does not allow router to connect to normal server (it expects
5054 that normal server always initiates the connection to the router)
5055 so the CONNECT command is only good for connecting to another
5058 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5061 or some other client was kicked from the channel.
5063 Implemented the handling of the notify type to both client
5066 Implemented silc_server_send_notify_kicked to send the KICKED
5067 notify. It is used to send it to the server's primary router.
5069 * Implemented the KICK command into server and client.
5071 * Added `query' argument to the silc_idlist_get_client function
5072 to indicate whether to query the client from server or not if
5075 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5076 to indicate that the client is not channel founder.
5080 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Removed the rng context from SilcPacketContext structure and
5083 changed that the packet routine uses the Global RNG API.
5085 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Added support for quit message that client can "leave" on the
5088 channel when it quits the SILC. It is ditributed inside the
5089 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5091 Added silc_server_free_client_data that will take the
5092 signoff message as argument.
5094 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5096 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Updated parts of the protocol specification to keep it up
5101 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5104 payloads in one packet.
5106 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5107 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5108 use now the new List flag.
5110 * Also deprecated the following packet types: REPLACE_ID,
5111 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5113 * Added list support for Notify packet in server.
5115 * Added silc_server_send_notify_channel_change to send the
5116 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5117 the silc_server_send_replace_id.
5119 * Added silc_server_send_notify_nick_change to send the
5120 NICK_CHANGE notify type. Deprecates the function
5121 silc_server_send_replace_id.
5123 * Added silc_server_send_notify_join to send the JOIN notify type.
5124 Deprecates the function silc_server_send_new_channel_user.
5126 * Added silc_server_send_notify_leave to send LEAVE notify type.
5127 Deprecates the function silc_server_send_remove_channel_user.
5129 * Added silc_server_send_notify_cmode and
5130 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5131 types. Deprecates the silc_server_send_set_mode function.
5133 * Added SERVER_SIGNOFF notify type to indicate that server has
5134 quit. This means that all clients on the channel from that
5135 server will drop. This can be also used when netsplit happens.
5137 Deprecated REMOVE_ID packet type since it is not needed anymore
5140 Added silc_server_send_notify_server_signoff to send the
5141 SERVER_SIGNOFF notify type. Deprecates the function
5142 silc_server_send_remove_id.
5144 Added also silc_server_send_notify_signoff to send the
5145 SIGNOFF notify type.
5147 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5148 SILC protocol from this day on. Changed the protocol
5149 specification as well.
5151 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5152 notify type. It is used between routers to notify about
5153 topic changes on a channel.
5155 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5158 * Partly updated the protocol specification to comply with the
5159 changes now made. It is still though a bit outdated.
5161 * The JOIN notify type now takes one extra argument <Channel ID>.
5162 The packet used to be destined to the channel but now the
5163 JOIN type may be sent as list thus it is impossible to
5164 destine it to any specific channel. By adding this argument
5165 it is again possible.
5167 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Added CREDITS file. The CHANGES and CREDITS file will appear
5170 in the distribution as well.
5172 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5175 types in the server's silcd/packet_receive.c.
5177 * Implemented CMODE and CUMODE to work in router environment.
5179 * Fixed minor encoding and decoding buglet from the
5180 lib/silccore/silcmode.c.
5182 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5185 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5187 * Changed all SilcConfigServer* and silc_config_server* to
5188 SilcServerConfig* and silc_server_config*, respectively.
5191 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Associated the ID (client or server ID) to the Authentication
5194 Payload to avoid any possibility of forging. Updated the
5195 protocol specification and the code accordingly.
5197 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * The RSA key length is now save to the RsaKey context in the
5200 key generation process in lib/silccrypt/rsa.c. The key length
5201 is now used to figure out the maximum size of the block allowed
5202 to be encrypted/signed.
5204 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5205 is equivalent to the silc_mp_mp2bin but does not allocate any
5208 * Changed silc_mp_mp2bin API to take length argument. If it is
5209 non-zero then the buffer is allocated that large. If zero, then
5210 the size is approximated using silc_mp_sizeinbase, which however
5213 * Created Global RNG API which is global RNG that application can
5214 initialize. After initializing, any routine anywhere in the
5215 code (including library) can use RNG without allocating a new
5216 RNG object. This was done to allow this sort of use of the
5217 RNG in code that has no chance to allocate RNG object. All
5218 applications currently allocate this and many routines in the
5219 library use this. Affected file lib/silccrypt/silcrng.[ch].
5221 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5222 it to use the Global RNG API.
5224 * Defined Authentication Payload into protocol specification that
5225 is used during SILC session to authenticate entities. It is
5226 used for example by client to authenticate itself to the server
5227 to obtain server operator privileges.
5229 Implemented this payload into the lib/silccore/silcauth.[ch].
5230 Implemented also routines for public key based authentication
5231 as the new protocol specification dictates.
5233 Moved definitions of different authentication methods from
5234 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5236 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5237 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5238 silc_pkcs_verify_with_hash functions into the file
5239 lib/silccrypt/silcpkcs.[ch].
5241 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * The client entry's userinfo pointer must be always valid.
5244 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5245 will fail since it requires the userinfo. Now, the userinfo
5246 is allocated as "" if actual userinfo does not exist. Actually,
5247 it must exist and it is totally Ok to drop client connections
5248 that does not announce the userinfo. However, we will make
5249 this workaround for now.
5251 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5252 to return the remote port by socket.
5254 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5257 SILC_SERVER_PENDING_EXEC and added an new macro
5258 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5259 data or when error occurs while processing the pending command.
5261 Added new argument `destructor' into silc_server_command_pending
5262 and to the SilcServerCommandPending object. This destructor is
5263 now called after calling the pending callback or if error occurs
5264 immediately. If error occurs the actual pending callback won't
5265 be called at all - only the destructor. The destructor may be
5266 NULL if destructor is not needed.
5268 All this applies for client library code as well. Similar
5269 changes were made there as well for the pending commands.
5271 In the client, the application must now allocate the
5272 SilcClientCommandContext with the silc_client_command_alloc
5275 * Added reference counter to the SilcServerCommandContext. Added
5276 function silc_server_command_alloc and silc_server_command_dup
5279 Same type of functions added to the client library for the same
5282 * Removed the cmd_ident from IDListData away since it is now
5283 global for all connections. It is the command identifier used
5284 in command sending and with pending commands. The affected file
5287 * Added reference counter to the SilcSocketConnection objecet to
5288 indicate the usage count of the object. The object won't be
5289 freed untill the reference counter hits zero. Currently only
5290 server uses this, and client ignores it. The client must be
5291 set to use this too later. The affected files are
5292 lib/silccore/silcsockconn.[ch]. Added also the function
5293 silc_socket_dup to increase the reference counter.
5295 This was mainly added because it is possible that the socket
5296 is removed underneath of pending command or other async
5297 operation. Now it won't be free'd and proper DISCONNECTING
5298 flags, etc. can be set to avoid sending data to connection that
5299 is not valid anymore.
5301 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5302 the connection. After that it sets SILC_SET_DISCONNECTED.
5303 It is, however, possible that the socket data is not still freed.
5304 The silc_server_packet_process now checks that data is not
5305 read or written to connection that is DISCONNECTED. The socket
5306 get's freed when the reference counter hits zero.
5308 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Changed the client operation API: channel_message operation's
5311 `sender' is now the client entry of the sender, not the nickname
5312 and the `channel' is the channel entry, not the channel name.
5314 In the private_message operation the `sender' is now also the
5315 client entry of the sender not the nickname.
5317 Affected file is lib/silcclient/ops.h and all applications
5318 using the client operations.
5320 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5322 * Moved the calling of ops->connect() from connect_to_server_final
5323 into receive_new_id functin since that is the point when the
5324 client is actually allowed to send traffic to network. The
5325 affected file is lib/silcclient/client.c.
5327 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5330 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5331 (if needs broadcasting) instead of broadcasting the packets one
5332 by one which would make a burst in the network traffic.
5334 * Added `broadcast' argument to the functions in silcd/server.[ch]
5335 silc_server_create_new_channel[_with_id] to indicate whether
5336 to send New Channel packet to primary router.
5338 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Added new function into the silcd/server.[ch] files:
5341 silc_server_create_new_channel_with_id to create new channel with
5342 already existing Channel ID.
5344 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5345 lib/silccore/silcpacket.h. This packet is used t send list of
5346 Set Mode payloads inside one packet. Server uses this to set
5347 the modes for the channels and clients on those channels, that it
5348 announced to the router when it connected to it. The protocol
5349 specification has been updated accordingly.
5351 * The silc_server_new_channel did not handle the packet coming
5352 from normal server as it normally does not send that. However,
5353 when it announces its channels it does send it. Implemented
5354 the support for that.
5356 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5357 into the file lib/silccore/id.h.
5359 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Fixed memory leaks in the functions silc_idlist_del_client,
5362 silc_idlist_del_channel and silc_idlist_del_server in the file
5363 silcd/idlist.c. All of those leaked like a sieve.
5365 * Fixed some small memory leaks in the client's function
5366 silc_client_notify_by_server.
5368 * Added functions into silcd/server.c: silc_server_announce_clients,
5369 silc_server_announce_channels and silc_server_announce_server.
5370 These functions are used by normal and router server to announce
5371 to its primary router about clients, channels and servers (when
5372 router) that we own. This is done after we've connected to the
5375 These functions effectively implements the following packet types:
5376 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5377 and SILC_PACKET_NEW_ID_LIST.
5379 * Added new functions into the silcd/packet_receive.[ch]:
5380 silc_server_new_id_list, silc_server_new_channel_list and
5381 silc_server_new_channel_user_list to handle the incoming
5382 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5384 * Added support of changing Channel ID in the function
5385 silc_server_replace_id. If the server that announces a channel
5386 to the router already exists in the router (with same name but
5387 with different Channel ID), router is responsible to send
5388 Replace ID packet to the server and force the server to change
5389 the Channel ID to the one router has.
5391 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5392 client that the Channel ID has been changed by the router. The
5393 normal server sends this to the client. Client must start using
5394 the new Channel ID as the channel's ID.
5396 Implemented handling of this new type into lib/silcclient/client.c
5397 into the function silc_client_notify_by_server.
5399 * Added new function silc_idlist_replace_channel_id into the files
5400 silcd/idlist.[ch] to replace the Channel ID.
5402 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Call silc_server_command_identify_check always when processing
5405 the IDENTIFY command in silcd/command.c
5407 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5410 send keepalive packets. The packet can be sent by clients,
5411 servers and routers.
5413 Added function silc_socket_set_heartbeat into the file
5414 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5415 If not set, the heartbeat is not performed. The actual
5416 heartbeat is implemented in the low level socket connection
5417 library. However, application is responsible of actually
5420 Added silc_server_send_heartbeat to send the actual heartbeat
5421 packet into silcd/packet_send.[ch]. Server now performs
5422 keepalive with all connections.
5424 * Added silc_task_get_first function into lib/silcutil/silctask.c
5425 to return the timeout task with shortest timeout. There was a bug
5426 in task unregistration that caused problems. TODO has been
5427 updated to include that task system must be rewritten.
5429 * The client library will now resolve the client information when
5430 receiving JOIN notify from server for client that we know but
5431 have incomplete information.
5433 * Rewrote parts of silc_server_remove_from_channels and
5434 silc_server_remove_from_one_channel as they did not remove the
5435 channel in some circumstances even though they should've.
5437 * Encryption problem encountered in server:
5439 The LEAVE command used to send the Channel Key packet to the
5440 router immediately after generating it. However, the code
5441 had earlier sent Remove Channel user packet but not immediately,
5442 ie. it was put to queue. The order of packets in the router
5443 was that Channel Key packet was first and Remove Channel User
5444 packet was second, even though they were encrypted in the
5445 reverse order. For this reason, MAC check failed. Now, this
5446 is fixed by not sending the Channel Key packet immediately but
5447 putting it to queue. However, this is more fundamental problem:
5448 packets that are in queue should actually not be encrypted
5449 because packets that are sent immediately gets encrypted
5450 actually with wrong IV (and thus MAC check fails). So, packets
5451 that are in queue should be encrypted when they are sent to
5452 the wire and not when they put to the queue.
5454 However, the problem is that the current system has not been
5455 designed to work that way. Instead, the packet is encrypted
5456 as soon as possible and left to the queue. The queue is then
5457 just purged into wire. There won't be any fixes for this
5458 any time soon. So, the current semantic for packet sending
5461 o If you send packet to remote host and do not force the send
5462 (the packet will be in queue) then all subsequent packets to the
5463 same remote host must also be put to the queue. Only after the
5464 queue has been purged is it safe again to force the packet
5467 o If you send all packets immediately then it safe to send
5468 any of subsequent packets through the queue, however, after
5469 the first packet is put to queue then any subsequent packets
5470 must also be put to the queue.
5472 Follow these rules and everything works fine.
5474 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Added new function silc_server_remove_clients_by_server to
5477 remove all client entries from ID list when the server connection
5478 is lost. In this case it is also important to invalidate all
5479 client entires as they hold the invalid server entry. This
5480 fixes fatal bug when server has lost connection and will reconnect
5483 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Made some sanity checks to silc_server_daemonise like to check
5486 whether the requested user and group actually exists.
5488 * Added sanity check to SKE's silc_ske_responder_finish to check
5489 that the public and private key actually is valid.
5491 * Invalidate the client's nickname when receiving Replace ID
5492 packet and the Client ID is being replaced. This means that the
5493 server will query the nickname if someone needs it (client)
5496 * Sort the ID Cache in client library when the ID Cache data
5497 has changed (needs sorting).
5499 * Do not allow for SILC client to create several connections to
5500 several servers. The client does not support windows right now
5501 and generating multiple connections causes weird behaviour.
5503 Irssi-silc client does support windows and can handle several
5504 connections without problems, see: www.irssi.org and SILC plugin.
5506 * Fixed some places where client was added to the IDList. The
5507 rule of thumb is following (in order to get everything right):
5508 If the client is directly connected local client then the
5509 `connection' argument must be set and `router' argument must be
5510 NULL to silc_idlist_add_client function. If the client is not
5511 directly connected client then the `router' argument must
5512 bet set and the `connection' argument must be NULL to the
5513 silc_idlist_add_client function.
5515 * The funtion silc_server_packet_send_local_channel actually did
5516 not check whether the client was locally connected or not. It
5517 does that now. Fixed a bug related to LEAVE command.
5519 * Fixed Remove Channel User payload parsing bug in server's
5520 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5522 * The server's silc_server_save_channel_key now checks also the
5523 global ID list for the channel as it might not be in the local
5524 list. Fixed a bug related to LEAVE command.
5526 * Is this the end of the [<unknown>] buglet that has been lurking
5527 around for a long time? A little for loop fix in server's
5528 silc_server_command_whois_parse that is used by both IDENTIFY
5529 and WHOIS command. At least, this was a clear bug and a cause
5530 of one type of [<unknown>] buglet.
5532 * WHOIS and IDENTIFY commands call the function
5533 silc_server_command_[whois/identify]_check function even if
5534 we are not router server.
5536 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added --with-gmp configuration option. If set the GMP
5539 is always compiled in the SILC source tree. If not set then
5540 it is checked whether the system has the GMP3 installed. If
5541 it has then the GMP won't be compiled (the system's headers
5542 and library is used), if it doesn't have it then the GMP is
5543 compiled in the SILC source tree.
5545 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Changed RSA private exponent generation to what PKCS #1
5548 suggests. We try to find the smallest possible d by doing
5549 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5550 not security fix but optimization.
5552 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Added new config entry [Identity] to fork the server and run
5555 it as specific user and group. A patch from Bostik.
5557 * Imported Dotconf configuration library into lib/dotconf.
5558 This will be used to create the SILC configuration files later.
5559 It will appear in the distsribution after this commit.
5561 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * A big code auditing weekend happening. Auditing code for
5564 obvious mistakes, bugs and errors. Also, removing any code
5567 Removed files for being obsolete:
5569 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5570 inline in the file lib/silcutil/silcbuffer.h)
5572 o lib/silcutil/silcbufutil.c (the header has inline versions)
5574 Changed code to fix possible error conditions:
5576 o The buffer formatting routines now check that the destination
5577 buffer really has enough space to add the data. This applies for
5578 both buffer formatting and unformatting
5579 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5580 unformatting was changed to accomodate following rules:
5581 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5582 sent to the function while XXX_*STRING will not allocate or copy
5583 the data into the buffer. Instead it sets the pointer from the
5584 buffer into the pointer sent as argument (XXX_*STRING used to
5585 require that the pointer must be allocated already). This change
5586 makes this whole thing a bit more consistent and more optimized
5587 (note that the data returned in the unformatting with XXX_*STRING
5588 must not be freed now). The routines return now -1 on error.
5590 o Tried to find all code that use buffer_format and buffer_unformat
5591 and added return value checking to prevent formatting and
5592 especially unformatting errors and possible subsequent fatal
5595 o Changed ske->x and ske->KEY to mallocated pointers in
5596 lib/silcske/silcske.h. Fixed possible data and memory leak.
5598 o Added return value checking to all *_parse* functions. Fixed
5599 many memory leaks as well.
5601 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5602 so that buffer overflows would not happen. All code now also
5603 checks the return value as it can fail.
5605 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Added reconnection support to server if the normal server looses
5608 its connection to the router (for example if router is rebooted).
5609 The server performs normal reconnection strategy implemented
5610 to the server. Affected file silcd/server.c.
5612 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Added new packet type SILC_PACKET_SET_MODE that is used to
5615 distribute the information about changed modes (for clients,
5616 channels and clients channel modes) to all routers in the
5617 network. Updated the protocol specification accordingly.
5619 Added functions into silcd/packet_send.c and
5620 silcd/packet_receive.c: silc_server_send_set_mode,
5621 silc_server_set_mode.
5623 Added new files silcmode.[ch] into lib/silccore that implements
5624 the encoding and decoding of Set Mode Payload. Added new type
5625 SilcSetModePayload. Moved the definitions of different modes
5626 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5628 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Oops, a little mistake in server's connection authentication
5631 protocol. The protocol is not ended with FAILURE but with
5632 SUCCESS if the authentication is Ok. :) Affected file is
5635 * Implemented NICK_CHANGE notify handling in server in the file
5636 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5637 the local clients on the channel. After the changing nickname
5638 in router environment snhould work and the [<unknown>] nickname
5639 should appear no more.
5641 The silc_server_replace_id function that receives the Replace ID
5642 payload now sends the NICK_CHANGE notify type also in the file
5643 silcd/packet_receive.c
5645 * Changed WHOIS and IDENTIFY command to support the maximum amount
5646 of arguments defined in protocol specs (3328 arguments). This
5647 fixed a bug that caused problems when there were more than three
5650 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added extra parameter, command identifier, to the
5653 silc_client_send_command so that explicit command identifier
5656 Changed that ID list routines uses specific command identifier
5657 when sending WHOIS/IDENTIFY requests to the server so that they
5658 can be identified when the reply comes back.
5660 Affected files lib/silcclient/command.[ch],
5661 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5663 * Added `sender' argument to silc_server_packet_send_to_channel
5664 to indicaet the sender who originally sent the packet to us
5665 that we are now re-sending. Ignored if NULL. Affected file
5666 silcd/packet_send.[ch].
5668 * Added some server statistics support in silcd/server_internal.h
5669 SilcServerStatistics structure and around the server code. Also
5670 send some nice statistics information when client is connecting
5673 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Fixed channel ID decoding in server's JOIN command reply in
5676 silcd/command_reply.c
5678 * Fixed braodcasting of replace ID payload to not to send it if
5679 we are standalone server in silcd/packet_receive.c.
5681 * Fixed all channel message sending routines to not to send
5682 packets to clients that has router set, since they are routed
5683 separately in the same function earlier. Affects file
5684 silcd/packet_send.c and all channel packet sending functions.
5686 * In USERS reply, res_argv[i] are not allocated, the table
5687 is allocated. Thus changed that free the table, not its
5690 * In server's whois_check and identify_check if the client is
5691 locally connected do not send any WHOIS commands - they are not
5694 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Fixed some minor bugs in client when sending WHOIS command. The
5697 arguments was in wrong order.
5699 * Removed statis function add_to_channel from server in
5700 silcd/command.c that was previously used with the joining but
5703 * Tested USERS command in router environment successfully with two
5704 routers, two servers and two clients.
5706 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Reorganized the USERS command and command reply in client library
5709 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5710 When the command is given by user we register a pending command
5711 callback that will reprocess the command after the reply has been
5712 received from the server. When reprocessing the packet we then
5713 display the information. Thus, the USERS information is displayed
5714 now in the command callback instead of in the command reply
5715 callback. The processing of the command is same as previously
5716 when server has sent the command reply in the JOINing process.
5718 * Added to USERS command in silcd/command_reply.c to join the client,
5719 we didn't use to know about, to the channel after we've created
5720 a client entry for it. Also, for clienet we did know already still
5721 check whether it is on the channel or not and add it if not.
5723 * Removed silc_server_command_join_notify as the function and its
5726 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Changed the client's pending command handling to the same as the
5729 server's pending command handling. It is also now possible to
5730 execute command reply functions from other command reply
5731 function as the function callbacks for commands and command
5732 replies are one and same. The pending commands are not static
5733 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5734 in client connection context. Thus, pending commands are server
5735 connection specific as it is convenient.
5737 Changed the function silc_client_command_pending and
5738 silc_client_command_pending_del and added new function
5739 silc_client_command_pending_check. Removed the
5740 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5743 * Added cmd_ident, current command identifier, to the client
5744 connection context in lib/silcclient/client.h to keep track on
5745 command identifiers used in command sending. Client's command reply
5746 function handling now supports the mandatory command identifiers.
5748 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5749 funtions in client to fully support pending command callbacks.
5751 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5752 as one of the arguments to the application in the command reply
5755 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5756 before first releasing SILC but came back. Now it is removed again
5757 and should come back nomore. The FORWARDED flag was used only
5758 by the JOINing procedure by forwarding the command packet to router.
5759 Now, the JOINing procedure has been changed to more generic (due
5760 to various router environment issues) and FORWARDED is not needed
5761 anymore for anything. The protocol specification is yet to be
5764 Now, removed silc_server_packet_forward from server and the flag
5765 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5767 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Renamed NAMES command to USERS command. The NAMES was named that
5770 due to historical reasons. Now it is renamed. Also, rewrote
5771 parts of the USERS command. The nickname list is not sent anymore
5772 by the server. Only Client ID and mode lists are sent in the USERS
5773 command. Changed this also to the protocol specification.
5775 The client now resolves the names and stuff after it receives
5776 the USERS list from the server when joining to the channel.
5778 * WHOIS and IDENTIFY commands has been changed to support multiple
5779 Client ID's per command. One can now search for multiple users
5780 in the network by sending only one WHOIS or IDENTIFY command.
5781 Changed the code and the protocol specifications.
5783 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5784 uses silc_server_command_whois_parse to parse the request. */
5786 * If normal server, do not parse the WHOIS and IDENTIFY requests
5787 before sending it to the router. Saves some time.
5789 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Fixed JOIN command on client library. Wrong number of arguments
5792 used to crash the client.
5794 * Added silc_server_channel_has_global function to check whether
5795 channel has global users or not.
5797 * Added silc_server_channel_has_local function to check whether channel
5798 has locally connected clients on the channel.
5800 * The silc_server_remove_from_one_channel now checks whether the
5801 channel has global users or not after given client was removed from
5802 the channel. It also checks whether the channel has local clients
5803 on the channel anymore. If it does not have then the channel entry
5804 is removed as it is not needed anymore.
5806 * The silc_server_notify now checks on JOIN notify whether the joining
5807 client is one of locally connected or global. If it is global then
5808 the channel has now global users on the channel and that is marked
5809 to the channel entry. Also, it now saves the global client to
5810 global list who is joining and JOINs it to the channel. This is
5811 for normal server, that is.
5813 Changed silc_server_send_notify_on_channel,
5814 silc_server_packet_relay_to_channel and
5815 silc_server_packet_send_to_channel check if we are normal server
5816 and client has router set (ie. global client) do not send the
5817 message to that client, as it is already routed to our router.
5819 * Implemented LEAVE notify type handling in silc_server_notify
5822 * Tested LEAVE command in router environment successfully. Tested
5823 with two routers, two servers and two clients.
5827 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5829 * Implemented SIGNOFF notify type handling in silc_server_notify
5832 * silc_server_remove_id now removes the client entry from all channels
5833 it has joined and thusly sends SIGNOFF notify type.
5835 * Rewrote the NAMES list generation in server by removing two excess
5836 loops. The lists are created now inside one loop.
5838 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * silc_server_remove_channel_user checks now also global list
5841 for channel and client.
5843 * silc_server_new_channel_user checks now both local and global
5844 list for channel and client. Fixed a bug in client id decoding.
5845 Used to decode wrong buffer.
5847 * silc_server_channel_message checks now both local and global
5848 list for channel entry.
5850 * Tested channel joining (hence JOIN) in router environment
5851 successfully. Tested with two routers, two servers and two
5854 * Tested channel message sending in router environment successfully.
5856 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added silc_server_save_channel_key into server.[ch] to save the
5859 received channel key in Channel Key payload processing. It is
5860 also used in JOIN command reply handling.
5862 Equivalent function silc_client_save_channel_key added into
5863 client.[ch] into client library.
5865 * Changed JOIN command reply to send information whether the channel
5866 was created or not (is existing already) and the channel key
5867 payload. Changed protocol specs accordingly.
5869 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5870 the request was sent by ID and not by nickname. Crashed on
5873 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5876 now correctly save the received data.
5878 * silc_server_free_sock_user_data now notifies routers in the
5879 network about entities leaving the network.
5881 At the same time implemented functions silc_server_remove_id
5882 and silc_server_send_remove_id to receive and send REMOVE_ID
5883 packets. The packet is used to notify routers in the network
5884 about leaving entities. The ID removed will become invalid in
5887 * Added function silc_idlist_del_server into server. Removes and
5888 free's server entry from ID list.
5890 * silc_server_private_message function now checks, if we are router,
5891 that the destination ID really is valid ID, naturally.
5893 * In router when NEW_ID packet is received (for new client) the
5894 hash of the Client ID is saved in the ID Cache but the
5895 client->nickname is set to NULL, instead of putting the hash
5898 IDENTIFY command now also checks that client->nickname must be
5899 valid. If it is not if will request the data from the server who
5900 owns the client. Added new function
5901 silc_server_command_identify_check.
5903 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5904 to set the command to already allocated Command Payload.
5906 * Tested private message sending in router environment with two
5907 routers, two servers and two clients. Fixed minor bugs and now
5910 * Fixed segfault from client's NAMES command. Used to crash if
5913 * Forwarded packets must not be routed even if it is not destined
5914 to the receiver. Changed server code comply with this.
5916 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added `require_reverse_mapping' boolean value to ServerParams
5919 structure. If TRUE (not default) the server will require that
5920 the connecting host has fully qualified domain name.
5922 If the reverse mapping is not required and hostname could not be
5923 found the IP address is used as hostname.
5925 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Implemented version string checking to both client and server.
5928 The check is incomplete currently due to the abnormal version
5929 strings used in development version of SILC.
5931 * Changed all command functions in server to use the new
5934 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * Changed char *data to unsigned char *data in ID Cache system to
5937 support binary data as ID Cache data. Changed code to support
5938 binary data in lib/silccore/idcache.c.
5940 * Renamed silc_server_packet_relay_command_reply to
5941 silc_server_command_reply as it is normal packet receiving
5942 function. Rewrote the function to accept command replys for
5943 servers and not only for clients.
5945 * Mark remote router always as registered server if we are connecting
5946 to it. Otherwise, commands sent by the router to us are ignored.
5948 * All ID List find routines now returns the ID Cache Entry pointer
5949 as well if requested.
5951 * WHOIS command works now in router environment, tested with two
5952 routers, two servers and two clients.
5954 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5955 in router environment (as it is almost equivalent to WHOIS) but
5956 hasn't been tested thoroughly. Added new functions:
5958 silc_server_command_identify_parse
5959 silc_server_command_identify_send_reply
5960 silc_server_command_identify_from_client
5961 silc_server_command_identify_from_server
5963 * Disabled route cache adding because adding two different ID's with
5964 same IP replaces the old cache entry thus giving wrong route.
5965 The entry->router->connection is always the fastest route anyway
5966 so route cache may not be needed. Of course, new routes maybe
5967 established after receiving the ID when the entry->router->connection
5968 might not be anymore the most optimal.
5970 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Add route cache for received ID for fast routing.
5974 * Added silc_server_packet_route to route received packet on router
5975 that is not destined to us.
5977 * Renamed silc_server_get_route to silc_server_route_get.
5979 * Added id_string and id_string_len fields into SilcServer to
5980 include encoded ServerID for fast comparing without excess
5981 encoding of the ID's.
5983 * Cleaned up WHOIS command on server side. Added following static
5986 silc_server_command_whois_parse
5987 silc_server_command_whois_check
5988 silc_server_command_whois_send_reply
5989 silc_server_command_whois_from_client
5990 silc_server_command_whois_from_server
5992 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5993 arguments in command replies. All command functions should be
5994 updated to use this macro.
5996 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Minor typo fixes on command reply handling on server.
6000 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Added silc_server_command_add_to_channel internal routine to add
6003 the client to the channel after router has created the channel and
6004 sent command reply to the server.
6006 * Added generic silc_server_send_command to send any command from
6009 * Use static buffer with ID rendering instead of duplicating data.
6011 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6013 * Fixed a channel user mode bug when joining to a channel server gave
6014 everybody channel founder rights, oops.
6016 * We mark ourselves as the router of the incoming server connection
6017 if we are router ourselves. This way we can check in some packet
6018 sending functions whether it is locally connected server. For
6019 incoming router connections we put NULL.
6021 * For router sending packets locally means now always sending the
6022 packet cell wide; to local clients and local servers. For normal
6023 server sending packet locally means sending it to only local
6026 * Fixed the JOIN command to really work in router environment. If the
6027 channel is created it is always created by the router. Router is
6028 also responsible of making the initial joining to the channel,
6029 sending JOIN notify to the sending server and distributing
6030 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6031 does not exist server doesn't do anything else but forward the
6032 command to the router which performs everything.
6034 * Added silc_server_send_channel_key function to send the Channel Key
6037 * Added silc_server_create_channel_key to create new channel key. The
6038 channel key is now re-generated everytime someone joins or leaves
6039 a channel, as protocol dictates. Note: channel->key_len is the
6042 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6045 packet_receive.[ch] to separate packet sending and receiving
6046 routines. The server.[ch] now includes everything else including
6047 actual packet processing (writing and reading data) and other
6050 Renamed silc_server_private_message_send_internal to
6051 silc_server_send_private_message. The routine is still though
6052 used only to relay private messages as server does not send
6053 private messages itself.
6055 Renamed silc_server_new_channel to silc_server_create_new_channel
6056 and added new function sicl_server_new_channel that handles the
6057 incoming New Channel packet. Added also new sending function
6058 silc_server_send_new_channel to send New Channel Payload.
6060 * Added new function silc_server_notify to process incoming notify
6061 packet to the server/router. Server may then relay the notify
6062 to clients if needed.
6064 * Added new function silc_server_new_channel_user to process incoming
6065 New Channel User packet. Router will redistribute the packet and
6066 send JOIN notify to its local clients and locally connected servers
6067 if needed. Normal server will send JOIN notify to its local client
6068 on same channel when received this packet. Added also corresponding
6069 sending function silc_server_send_new_channel_user to sent the
6072 * Added boolean route argument to send_notif_to_channel and
6073 packet_send_to_channel functions to attempt to route the packet
6074 if it is TRUE and send only locally if it is FALSE.
6076 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6078 * silc_server_replace_id now broadcasts the received replace ID
6079 packet if it is not broadcast packet already. The router must
6080 broadcast to inform other routers about changed ID.
6082 * Added backpointer to server's router into SilcServer context in
6083 silcd/server_internal.h.
6085 * Fixed silc_server_packet_broadcast to send correct broadcast
6088 * The channel key is now distributed to the local client as soon
6089 as it is received from the router (in router environment) so that
6090 no other packet may be sent for the channel until client has
6093 * silc_server_remove_channel_user now broadcasts the received
6094 Remove Channel User packet if it is not broadcast packet already.
6095 The router must broadcast to inform other routers about removed
6098 * Added users field into SilcPacketContext that is a reference count
6099 of the context. One can increase the reference count by calling
6100 silc_packet_context_dup which is now changed to just increase the
6101 reference count instead of duplicating the data. The reference
6102 count is decresed by calling silc_packet_context_free that will
6103 free the data after the reference count hits zero.
6105 For now on the packet context and everything allocated into it
6106 (including the raw packet from network) must be freed by calling
6107 the new silc_packet_context_free function. Added also new function
6108 silc_packet_context_alloc that must be used now to allocate the
6109 context. This also means that if a routine is asynchronous from
6110 silc_[client/server]_packet_parse_type the packet context must
6111 be duplicated by calling silc_packet_context_dup. Otherwise it
6112 gets free'd after silc_[client/server]_packet_parse_type returns.
6113 Also, one must remember that if packet is duplicated then its
6114 reference count must be decresed by calling the free function as
6115 many times as it was duplicated.
6117 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6118 from both client and server.
6120 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Made joining to a channel working in router environment.
6124 * Cleaned up JOIN command on server side and create function
6125 silc_server_command_join_channel internal routine to make the
6128 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Changed silc_command_pending list to SilcDList. Also, added
6131 `ident' field to SilcServerCommandPending structure to identify
6132 the reply and to call correct callback.
6134 Added silc_server_command_pending_check function to replace the
6135 corresnponding macro. The silc_command_pending list is not
6138 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6139 to set identifier to previously allocated Command Payload. It
6140 is used to set identifier for command when resending Command
6143 * Added silc_command_payload_encode_payload to encode Command
6144 Payload buffer from SilcCommandPayload structure.
6146 * Added silc_argument_payload_encode_payload to encode Argument
6147 payload buffer from SilcArgumentPayload structure.
6149 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Changed WHOIS command to support router connection on server side.
6152 The whois request is always sent to router unless the server is
6153 standalone server. After server has received the reply from the
6154 router will it send the reply to the client.
6156 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6157 broadcast received broadcast packet. The function is used only
6158 by router. The broadcast packet is always sent to the router's
6161 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6162 render given ID to printable string, for log files for example.
6164 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Made basic router to router connections working. At least they
6167 can now connect to each other but nothing really works the way
6168 they are supposed - yet.
6170 * Added new initiator token to RouterConnection configuration
6171 file in silcd/serverconfig.[ch]. It is used to tell whether we
6172 are the initiator to the remote router or whether we'll expect
6173 the other end to connect.
6175 * Moved registering of listener task to silc_server_init, hence
6176 the server starts listenning as soon as it is run, even if it
6177 does not have connections to other routers. Let's see how well
6180 * Changed default connection retry timeouts for more suitable in
6183 * Removed cipher and such arguments from silc_idlist_add_client
6184 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6185 Added new function silc_idlist_add_data to add the keys and stuff
6188 * Added SilcIDListData structure and added it to SilcClientEntry
6189 and SilcServerEntry as their first field in the structure. This
6190 way we can explicitly cast the ID entries to the SilcIDListData
6191 structure and get common data for the entries. In past, we had
6192 to first check what type of connection it is and then cast it to
6193 correct ID entry type. Now, we can directly cast the opaque
6194 pointer to the SilcIDListData (no matter what ID entry it actually
6195 is) and get the data needed.
6197 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6200 in some circumstances even if threre were timeout tasks, though not
6201 IO tasks, but tasks anyway. Now fixed.
6203 * Defined SilcServerConnection structure to hold connection specific
6204 stuff about directly connected servers and routers. The definition
6205 is currently in silcd/server_internal.h. I thought about having
6206 a bit more important role fro this struct but for now it is used
6207 only when connecting to other server (or router actually).
6209 * Added connecting retry support in server when connecting to
6210 router(s). The retry feature implement exponential backoff
6211 algorithm. Also, added SilcServerParams structure to hold default
6212 parameters for server. For now, it include these retry settings
6213 and are hard coded. After server is moded to be as Silc Server
6214 Library this structure will be more important.
6216 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Changed client librarys channel->clients table to SilcList and
6219 changed code accordingly.
6221 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Changed client's channel table to SilcList and changed code
6224 accordingly. Also changed SilcChannelClientEntry to include back-
6225 pointer to the channel so that client entry can use that structure
6226 as list as well and we have fast cross-reference to the channel.
6227 This change dramatically decreased the complexity of channel
6228 handling with client entry and vice versa (removed one extra
6229 loop when searching for channel entry from many functions).
6231 * Changed server->sim from table to SilcDList and changed code
6234 * NAMES command can now be used from user interface. It will show
6235 the user list on the channel, neatly.
6237 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6238 Code now saves realname of the user if it becomes available.
6240 * Renamed configure.in to configure.in.pre and made ./prepare
6241 script to automatically add correct version string to
6242 configure.in which it creates from configure.in.pre.
6244 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * NAMES command reply now shows users mode with the nickname when
6249 * Moved silc_client_ch[u]mode[_char] functions from
6250 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6251 place sucks, they are utility functions and should be in some
6254 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6256 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6259 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Added TRQ (efficient deque and list library) into lib/trq. This is
6264 a very good list library that is currently used in the SILC. Defined
6265 SilcList API over the library because I didn't like the API very
6266 much. See lib/trq/silclist.h for the API and examples of how to
6267 use the API. Fixed various places in the code to use the new
6268 SilcList API. The SilcList is meant for lists that has a structure
6269 already defined as a list. It is not suitable to add just some
6270 context to the list (in TRQ, the context is the list actually).
6272 So, I defined SilcDList that can be used for the purpose where
6273 predefined list structure does not exit. This can be used as
6274 such list. Now some context just can be added to the SilcDList.
6275 Currently this list is not used in the SILC just yet, though there
6276 are a lot places where this can replace dynamically allocated
6277 tables and I will fix these places, later, to use SilcDList.
6278 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6279 and use TRQ internally).
6281 Also fixed some annoying warning messages that the original TRQ
6282 code generated. Also minor changes to TRQ's Makefile.in.
6284 * Added support for querying by Client ID to both WHOIS and
6285 IDENTIFY commands into server, as required by the protocol.
6287 * Removed method function pointers from SilcBuffer structure. They
6288 weren't used to anything and just increased the context size for
6289 no good reason. This change also made silc_buffer_alloc and
6290 silc_buffer_free functions inline functions.
6292 * Disabled command flooding detection support until it's fixed so
6293 that it accepts commands in but does not execute them more than once
6296 * Added silc_net_localhost(), to return local hostname, into
6297 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6298 that must be initialized before calling silc_client_init.
6300 * Added new function: silc_server_send_notify_on_channels to send
6301 notify messages to all channels client has joined. It is assured
6302 that the message is sent only once per client.
6304 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6305 lib/silcutil/silcutil.[ch] as silc_format function. The new
6306 function is generic and is used by server as well, not only by
6307 the logging routines.
6309 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6310 the provided version string was not acceptable. Added new function:
6311 silc_ske_check_version into lib/silcske/silcske.h. The function
6312 must be implemented by the application (client or server) and it
6313 does not reside in the SKE library. The function checks the version
6314 string remote end sent.
6316 * Added back pointers (to opaque context and to SilcSocketConnection)
6317 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6319 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6320 duplicate packet context structure.
6322 * Changed `notify' client operation to send same arguments as client
6323 receives from server except for ID's. ID's are mapped to correct
6324 ID entry and that is returned. Also, if channel entry is not sent
6325 by server but the notify is for channel the channel entry is sent
6326 to application (otherwise application doesn't know that it is for
6327 channel (library gets it from packet's Destination ID)).
6329 * Added silc_client_remove_from_channels into client library to
6330 remove a client from all channels it has joined to. Used when
6331 received SIGNOFF notify from server. Added also new function
6332 silc_client_replace_from_channels to replace old ID entry with
6333 new ID entry on all channels. Used when received NICK_CHANGE
6336 * Fixed ID Cache list handling in silc_idlist_get_client in
6337 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6338 to get (or query) client by ID.
6340 * Updated TODO list.
6342 * Added connection authentication status message defined by the
6343 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6344 support for these into the code in client and server side.
6346 * Added generic function silc_client_send_command to send any command
6347 with variable argument list. Application should use this function
6348 to send commands if the command functions provided by the library
6349 does not suite for the application's user interface needs.
6351 * Added new `failure' client operation. Application is notified about
6352 received failure packet if client is executing a protocol. In this
6353 case the protocol's execution has failed.
6355 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6356 is required by the protocol.
6358 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6359 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6362 * Added status flag to SilcSKE object to indicate realtime status
6363 of the SKE protocol.
6365 * Application receives now exactly same command reply arguments as
6366 the library receives from server. However, if ID is received the
6367 corresponding ID entry is returned to the application (eg. Client
6368 ID is mapped to correct SilcClientEntry entry and that is returned).
6369 Changed command_reply client operation due to this change.
6371 * Changed all ID's in commands and in command replys as ID Payloads.
6372 Change affected both client and server side codes.
6374 All ID's sent in SILC network (with execption of ID's in SILC
6375 Packet header) are sent in ID Payload to support variable length
6378 * Server now notifies nick changes and notifies all clients on
6379 the channels about the new nickname (about the new Client ID,
6382 * Implemented CMODE command to change channel modes. Supports all
6383 channel modes defined by the protocol specs except ban and invite
6384 lists. (Also, private channel key mode is supported but support for
6385 setting private channel key in client is missing, thus, this mode
6386 has no effect on client side (except that server requires that the
6387 client uses private channel key and normal channel traffic does not
6390 Also, invite mode works per se, but INVITE command does not work
6391 yet correctly, so you can set channel as invite only channel but
6392 inviting clients to the channel does not work (it is yet to be
6393 thought what's the best way to do it).
6395 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6396 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6397 Implemented CUMODE command to change user's mode on the channel.
6398 Supports all modes defined by the protocol specs.
6400 * Added NAMES command reply to return users modes on the channel.
6402 * Removed unnecessary and slow ciphers from lib/silccrypt.
6404 * Set SO_KEEPALIVE option to connection sockets by default.
6406 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6408 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6409 redefined the Notify Payload into protocol specs.
6411 * Added silc_id_payload_parse_id to get ID directly from raw
6414 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6417 accept searching by Client ID as well.
6419 * Added support for LEAVE and SIGNOFF notify types in client library.
6421 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6422 to parse ID Payload from raw data.
6424 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Added flags parameter into silc_ske_assemble_security_properties
6427 function in lib/silcske/silcske.[ch].
6429 * Changed notify client operation to fit better for notify messages
6430 sent by server. The notify payload received from server is now
6431 passed to the application (after parsing it to SilcNotifyPayload).
6432 It is application's responsibility to retrieve the arguments
6433 from the payload and show the message the way it wants. The message
6434 sent by server is implementation specific.
6436 * Changed public keys to comply with the protocol specification.
6437 Old public keys are not supported anymore and are not compatible.
6439 * Removed nickname from Channel Payload as the latest draft removed
6440 it. The client must resolve the nickname from the NAMES command
6441 reply received when it joined the channel.
6443 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6445 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Fixed some errors in protocol specification drafts.
6449 * Created lib/silccore/silcnotify.c to implement Notify Payload
6450 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6451 generic payloads described by protocol specifications. The file
6452 includes implementations for ID Payload and Argument Payload.
6454 * Changed Command Payload implementation to use the new Argument
6455 Payload. Changed command_xxxx_payload to command_payload_xxxx
6456 to comply with SILC coding conventions.
6458 * Added suppport for Argument Payload handling in Notify Payload
6459 implementation as protocol requires it. Added the new support
6460 into server and client lib as well.
6462 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added support for multiple nicknames on same channel. [n] is
6465 added locally to the nickname if there are more than one same
6466 nicknames on the channel.
6468 * Server now sends all nicknames that matched WHOIS request.
6469 Client also shows the list received from server.
6471 * Added TOPIC command to client side. User can now set and show
6472 current topic on channel.
6474 * Added MOTD command to client and server. Also, server sends the
6475 motd when client connects to the server.
6477 * Changed version strings to comply ISO 8601.
6479 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Fixed protocol error handling in client library. It should now
6482 cope even if the SKE fails for some reason.
6484 * Made new protocol specification drafts for submitting to IETF.
6486 * Implemented TOPIC command to server in silcd/command.c.
6488 * Added two new notify types into lib/silccore/silcnotify.h:
6489 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6490 notify nickname change and topic setting/change on a channel.
6492 * API change of command_reply operation in client library. The
6493 application gets now the status type received from server as well.
6495 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6499 * Cras fixed and optimized the packet handling even further and
6500 it should work now. Minor change to the prototype of function
6501 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6503 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6505 * Added new function into lib/silcutil/silcschedule.[ch]:
6506 silc_schedule_with_fd to select() a specified fd. The function
6507 returns after timeout expires or data arrives or goes. The
6508 function is used by packet routines to wait that all data is
6509 received from network.
6511 * Fixed data reading from network in lib/silccore/silcpacket.c.
6512 The code now assures that all data is read from the fd and then
6513 continues packet processing. This was a bug fix since the code
6514 used to drop some data in some circumstances.
6516 * Added new function into lib/silcclient/client.[ch]:
6517 silc_client_start_key_exchange to start key exchange after
6518 connection has been established to server. The code internally
6519 now uses this funtion but its main purpose was to provide it
6520 for applications that perform their own connecting. After
6521 application has created a connection it merely calls this
6522 function to start the key exchange between client and server.
6523 The library takes care of everything else after that.
6525 Updated also lib/silcclient/README to explain the usage of
6528 * Do not send to application information that connection has
6529 been established. Application gets notified it by connect
6532 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Applied cras's patch to add silc_schedule_one function. The
6535 function runs scheduler once and returns.
6537 * Fixed the scheduler after cras messed it up. The timeout
6538 handling works now as it's supposed to work.
6540 * Added into lib/silccore/ silcnotify.h to include notify
6541 message types support. Changed silc_server_send_notify*
6542 functions, in server.[ch], to support those new notify types.
6543 Added the support for the notify types into client library,
6544 as well. Added new notify client operation into ops.h in
6547 * Changed silc_server_packet_send_to_channel to send normal
6548 packets instead of just channel message packets. The function
6549 is now used to send the notify packets to channels. It is not
6550 used to send channel message packets anymore, as server never
6553 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6554 va_arg()s as it seems to require it nowadays. I guess, if SILC
6555 is compiled with older va_arg() the new code should work anyway.
6557 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Splitted core library. Core library (lib/silccore) includes
6560 now only SILC protocol specific core (and common) components.
6561 Created new utility library (lib/silcutil) that includes more
6562 generic purpose stuff. The stuff for util library was taken
6563 from the old core library. This was minor and easy split.
6565 * Created SILC Client Library (lib/silcclient) that includes
6566 implementation of the SILC client without user interface. This
6567 was major move from silc/ directory. The code has been changed
6568 so that it is transparent towards the user interface. The
6569 silc/ directory includes now the same user interface as before
6570 and it uses the new client library. Read lib/silcclient/README.
6571 Basicly, the client library performs everything else related
6572 to SILC except user interface handling. Also, configuration
6573 files are considered to be part of user interface and library
6574 does not handle them.
6576 This change also changed a lot of structures, function naming etc.
6577 Most important change was that SilcClientWindow object was
6578 renamed to SilcClientConnection in the client library. Created
6579 also new file lib/silcclient/ops.h. Also added new files
6580 silc/local_command.[ch] and silc/client_ops.[ch].
6582 All these changes were made to make it easier for user interface
6583 designers to create what ever user interface for the SILC client
6586 It is also expected that the server will be moved to lib
6587 directory as well and SILC Server Library will be created;
6588 sometimes in the future.
6590 * Removed Local commands from lib/silccore/silccommand.h as
6591 they are application specific and new client library does not
6592 handle any of those anymore.
6594 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6595 old client implementation in silc/.
6597 * Added support for callback functions in SILC_LOG_* macros.
6598 Application can now set its own callbacks that will be called
6599 instead of using the default functions that will always print
6600 the debug messages to stderr (or stdout). Also, debugging can
6601 now be disabled by setting silc_debug to FALSE and re-enabled by
6602 setting it to TRUE. Note, that logging will still work even
6603 if debugging is disabled.
6605 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6606 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6607 silc_log_reset_debug_callbacks.
6609 * To enable debugging in silc client one must give now -d
6610 option on command line.
6612 * Changed silc_schedule_init to automatically allocate task queues
6613 if they are not allocated before calling it.
6615 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Added GMP 3.1 into math library.
6619 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6622 a channel in SILC network. The packet is used by servers and
6623 routers to notify other routers that user has left a channel.
6624 This little feature was missing until now. Added the feature
6625 to protocol specification as well.
6627 Added functions: silc_server_send_remove_channel_user and
6628 silc_server_remove_channel_user into server.[ch].
6630 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6631 lib/silccore/silcpacket.h. However, they are not implemented
6634 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Fixed joining to a channel and sending channel messages
6637 between server and router. The channel message sending should
6638 now work inside a cell.
6640 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Fixed the private message sending between server and router.
6643 The private message sending should now work inside a cell.
6645 * Added silc_server_replace_id into server.[ch] to replace
6646 existing ID in the SILC network.
6648 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6649 and silc_idlist_replace_server_id into idlist.[ch] in server.
6651 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Fixed the server to server connections. Server can again now
6654 connect to router. Router to router connections probably does
6657 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added dynamic protocol registering support. Now protocols can
6660 registered and unregistered on the fly. Patch by cras.
6662 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Added lib/contrib directory to hold routines that some platforms
6665 don't have but are needed by SILC.
6667 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6668 into lin/contrib to provide getopt() and getopt_long() for
6669 those who don't have it.
6671 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6673 * Added AWAY command to client. When away message is set and
6674 client receives a private message packet the client automatically
6675 replies to the sender with the away message.
6677 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6678 bug seemed to be the cause of recent problems when compiling
6681 * Added version detection support to SKE protocol specification
6682 and added the new changes to the SKE implementation as well.
6683 There were other minor changes in the SKE protocol as well.
6685 Many changes in lib/silcske/silcske.[ch] and in
6686 lib/silcske/payload.[ch].
6688 * Added ^U functionality, clear input line. Patch from cras.
6690 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Mainly small bugfixes on core library. Fixed some debugging
6693 logging and buffer overflow in silclog.c.
6695 * Updated config.sub and config.guess on the distribution tree.
6697 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6699 * Added command lagging support in server. Client may execute
6700 commands now only once in two seconds.
6702 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Optimized packet reception. MAC computation and checking is now
6705 also more optimized. A lot previously duplicated code is now
6706 used as generic by both client and server.
6708 * Fixed key pair generation in clientutil.c
6710 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6712 * Added into lib/silccore/silcbufutil.[ch] new function;
6713 silc_buffer_realloc.
6715 * Moved generic packet sending/encryption functions to
6716 lib/silccore/silcpacket.[ch] from client and server. Some
6717 rewriting of the functions.
6719 * Moved all generic packet reception/decryption functions to
6720 lib/silccore/silcpacket.[ch] from client and server. The
6721 packet processing is now much cleaner in both client and server.
6722 These were major changes in both client and server.
6724 * Created many common functions in server to do packet sending.
6725 Previously code were duplicated a lot, this has been removed
6728 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6730 * Rewrote major parts of the ID cache system. Don't know
6731 whether it is better now or not but at least the API is more
6734 * Major rewrite on ID cache stuff on client because of the ID
6735 cache API changes. Added idlist.c to client.
6737 * Also major rewrite on ID cache stuff on server as well.
6738 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6739 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6740 in hand, instead they are all put into the ID cache system now.
6741 All server_idlist_* routines uses ID cache now instead of
6742 traversing its own lists (those lists does not exist anymore).
6743 SilcIDList though still exists. Also, SilcXXXEntry's are
6746 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6748 * Finally made the SKE implementation compliant to the protocol
6749 specification. All mp integers are now binary encoded as
6750 opposed being HEX encoded.
6752 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6755 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6756 functions: silc_[encode/decode]_pem. Also added function
6757 silc_encode_pem_file to PEM encode with newlines ('\n') for
6760 * SILC public keys are now encoded either PEM or binary. Same
6761 option is for private keys as well. By default private keys
6762 are binary encoded and public keys PEM encoded. Silly HEX
6763 encoding were removed.
6765 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6766 function to create fingerprints.
6768 * Fixed a bug in SHA1; does not change the original data anymore.
6770 * Partly implemented INFO command on client and server side.
6771 Fixed CLEAR command. Changes to SERVER command; show current
6772 server(s) when giving command without arguments. Added
6773 VERSION command to client.
6775 * Added check to server that unregistered connections cannot
6776 execute commands (unless it is specificly allowed).
6778 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Fixed screen refresh.
6782 * Fixed channel joining bug from client. On some circumstances
6783 client tried to join to a channel it had already joined.
6785 * Added public key verification process into client's protocol.c.
6786 The client now verifies the public key from user and saves
6787 it into ~./silc/serverkeys/ directory.
6789 Added into: clientutil.[ch]: silc_client_verify_server_key.
6791 * Changed SKE protocol's silc_ske_initiator_finish function
6792 to accept callback function that verifies the received public
6793 key. Removed old silc_ske_verify_public_key function.
6795 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6798 silc_pkcs_private_key[_data]_set.
6800 * Made the password and public authentication more cleaner in
6801 server's protocol.c.
6803 * Removed historic and obsolete protocol `channel_auth' from
6804 both client and server.
6806 * Removed wrong way of sending command status messages from
6807 server to client in server's command.c. The old way violated
6808 protocol specification.
6810 Changes to silccore/silccommand.[ch]: removed
6811 silc_command_encode_status_payload -> not needed anymore,
6812 changed silc_command_encode_payload_va to accept extra
6813 argument on variable argument list. The argument type must
6814 now be provided to the function. Also, added new function:
6815 silc_command_encode_reply_payload_va which is same as
6816 normal command_encode_payload_va except command status type
6817 is provided as extra argument.
6819 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added ~./silc directory handling. The directory includes the
6822 public and private keys for the client.
6824 Added silc_client_check_silc_dir, silc_client_create_identifier
6825 and silc_client_load_keys.
6827 * Implemented SILC protocol compliant public key. Added public
6828 and private key saving to and loading from files.
6830 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6831 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6832 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6833 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6834 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6836 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6837 silc_pkcs_load_[public/private]_key.
6839 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added silc_server_get_route (route.[ch]) to get connection
6842 data for the fastest route for given ID.
6844 * Implemented INVITE command on client and server. The command
6845 were re-defined in the SILC Protocol Specification and the
6846 implementation now complies with the specification.
6848 * Implemented PING command on client and server.
6850 * Implemented NAMES command on client and server. The server side
6851 supports currently only normal server not router server yet.
6852 Some changes to NAMES definition in SILC protocol specification.
6854 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Implemented LEAVE command on client and server.
6858 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6859 again. This change was made to the protocol as well. Server
6860 should not violate the protocol specification anymore.
6862 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6865 was tested. SOCKS4 was not but should work anyway.
