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

563 lib/silccrypt/silcpkcs.c
564 lib/silccore/silccommand.c
565 lib/silccore/silcidcache.c
570 * ROBOdoc documented the lib/silcske/groups.h file and a
571 bit changed the interface for better.
573 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
575 * Update the client entry context in the ID cache after
576 nick change. Affected file lib/silcclient/command.c.
577 Fixes the CUMODE command when regaining founder privileges,
578 and a little WHOIS problem.
580 * Fixed silc_net_gethostbyname to correctly call the
581 inet_ntop. Affected file lib/silcutil/silcnet.c.
583 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
585 * Added IPv6 support checking to the configure.in.pre, added
586 also --enable-ipv6 option to override the check. Affected
587 file configure.in.pre.

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

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

764 * Save fingerprint in WHOIS command reply in server.
765 Affected file silcd/command_reply.c.
767 * Fixed NICK commands pending callback registration.
768 Affected file lib/silcclient/command.c.
770 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
772 * Use ++server->cmd_ident when sending commands in server,
773 instead of random number. Affected file silcd/command.c.
775 * Fixed GETKEY command reply to call actually GETKEY pending
776 command callbacks. Affected file silcd/command_reply.c.
778 * A bit stricter check for nicknames. Check for same nickname
779 in NICK command also. Affected file silcd/command.c.
781 * Do not call INFO command everytime client ID changes, only
782 during first connecting. Affected file lib/silcclient/client.c.
784 * Set the new nickname only after successful command reply for
785 NICK command is returned by server. Affected file
786 lib/silcclient/command.c.
788 * Remove nicknames from nicklist during server_signoff notify.
789 Should fix /NAMES bit more. The affected file is
790 irssi/src/silc/core/silc-channels.c.
792 * Added `fingerprint' field to the SilcIDListData in the
793 silcd/idlist.h to hold the fingerprint of the client's
796 Send the fingerprint of the client's public key in WHOIS
799 Affected files silcd/command.c, and silcd/idlist.[ch].
801 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
802 create fingerprint from given data.
804 * Show the fingerprint of the client's public key in WHOIS.
805 Affected files irssi/src/module-formats.[ch] and
806 irssi/src/silc/core/client_ops.c.
808 * Format the multiple same nicknames also during JOIN and
809 NICK_CHANGE notifys. Affected file is
810 lib/silcclient/client_notify.c.
812 * Do not print error on screen for invalid private message
813 payload since it can come if someone is sending private
814 messages with wrong key. Affected file
815 lib/silccore/silcprivate.c.
817 * Fixed multiple concurrent /PING crash. Affected file
818 lib/silcclient/command.c.
820 * Changed the wrong ID encoding. All IP addresses must be
821 in MSB first order in encoded format. They were encoded
822 wrong and was in LSB format. Affected files are
823 silcd/serverid.c, lib/silcutil/silcutil.c.
825 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
827 * Call the `connect' client operation through the scheduler
828 in case of error. Affected file lib/silcclient/client.c.
830 * Call the `failure' client operation even if the error
831 occurred locally during a protocol. Affected file is
832 lib/silcclient/protocol.c.
834 * Added support of sending LIST command to router from normal
835 server. This way normal server can get list of all channels
836 in the network too. Fixed the channel list sending in the
837 server too. Affected files are silcd/command.c, and
838 silcd/command_reply.[ch].
840 * Added silc_server_update_channels_by_server and
841 silc_server_remove_channels_by_server. They are used during
842 disconnection of primary router and in backup router protocol.
843 Affected file silcd/server_util.[ch], silcd/server.c and
844 silcd/server_backup.c.
846 * Fixed channel adding to global list in IDENTIFY command
847 reply in server. Affected file silcd/command_reply.c.
849 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
851 * If the incoming packet type is REKEY or REKEY_DONE process
852 that packet always synchronously. Fixes yet another MAC
853 failed error on slow (dialup) connections. Affected file
854 lib/silcclient/client.c and silcd/server.c.
856 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Call check_version SKE callback for initiator too. Affected
859 file lib/silcske/silcske.c.
861 * Implemented fix for security hole found in the SKE that was
862 fixed in the specification few days back; the initiator's
863 public key is now added to the HASH value computation.
864 Added backwards support for the old way of doing it too, for
865 old clients and old servers. Affected file is
866 lib/silcske/silcske.c.
868 * Enabled mutual authentication by default in SKE. If initiator
869 is not providing mutual authentication the responder will
870 force it. This will provide the proof of posession of the
871 private key for responder. The affected files are
872 lib/silcclient/protocol.c and silcd/protocol.c.
874 * Do not cache anymore the server's public key during SKE.
875 We do mutual authentication so the proof of posession of
876 private key is done, and if the server is authenticated in
877 conn auth protocol with public key we must have the public
878 key already. Affected file silcd/protocol.c.
880 * Added new global debug variable: silc_debug_hexdump. If
881 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
882 file lib/silcutil/silclog.[ch].
884 * Fixed compilation warning due to char * -> const char *.
885 Affected files lib/silcutil/silcnet.h, and
886 lib/silccore/silcauth.[ch].
888 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Fixed CMODE command when new channel key was created. If
891 the creation failed the old key was removed. Next time giving
892 same command would crash the server since the old key was
893 freed already. Affected file silcd/command.c.
895 * Fixed the silc_server_announce_get_channels to not crash
896 on reconnect. Affected file silcd/server.c.
898 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Added silc_log_set_debug_string function to set a regex
901 string to match for debug output. Only the function names,
902 or filenames matching the given debug string is actually
903 printed. This way it is possible to filter out those debug
904 strings that user is not interested in.
906 Fixed a bug in silc_string_regexify.
908 Affected files lib/silcutil/silclog.[ch], and
909 lib/silcutil/unix/silcunixutil.c.
911 * Changed the -d options in both server and Irssi SILC client
912 to take the debug string as argument. Affected files
913 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
915 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
917 * Added silc_hash_babbleprint to create a Bubble Babble
918 Encoded fingerprint. The encoding is developed by Antti
919 Huima (draft-huima-babble-01.txt), and it creates human
920 readable strings out of binary data. Affected file
921 lib/silccrypt/silchash.[ch].
923 * Print the babble print now in addition of fingerprint as well
924 in Irssi SILC client. Affected files are
925 irssi/src/fe-common/silc/module-formats.[ch],
926 irssi/src/fe-common/silc/core/client_ops.c.
928 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed a security problem found in SKE. The initiator's
931 public key too is now added to the HASH hash value creation
932 which is signed by the responder to create the SIGN value.
933 This will prevent anyone in the middle to lie to the responder
934 about the initiator's public key. If this is done now, the
935 man in the middle will get caught. Updated the protocol
938 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Better installation directory handling. Configure module
941 paths and other paths automatically to example_silc* files
942 in doc/. A patch by toma.
944 * Fixed compiler warning from MPI library, and from SILC RNG.
947 * Added SILC_SERVER_PID_FILE to define the pid file for server.
948 It can be configured with ./configure. A patch by toma.
950 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
952 * Find correct make to use in prepare-clean. A patch by
953 toma. Affected file prepare-clean.
955 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
957 * Added irssi variables use_auto_addr, auto_bind_ip,
958 auto_bind_port and auto_public_ip.
960 * Changed the interface for silc_client_send_key_agreement
961 in lib/silcclient/silcapi.h
965 irssi/src/silc/core/silc-core.c
967 lib/silcclient/silcapi.h
968 irssi/src/silc/core/silc-channels.c
969 lib/silcclient/client_keyagr.c
972 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
974 * Added silc_pkcs_public_key_compare to compare two
975 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
977 * Check that the client who set the founder mode on the
978 channel is the same client that is giving the founder
979 mode to itself. It is done by comparing the saved public
980 key (it is saved even in the authentication is passphrase).
981 Affected file silcd/command.c.
983 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
985 * Do not process packet for disconnected socket connection.
986 Affected file lib/silccore/silcpacket.c.
988 * Process the DISCONNECT packet through scheduler in the
989 client library. Affected file lib/silcclient/client.c.
991 * Fixed the silc_client_packet_parse to not to increase
992 the packet sequence number if the conn->sock and the
993 current socket connection is not same. This can happen
994 for example during key agreement when the conn includes
995 multiple socket connections (listeners). Affected file
996 lib/silcclient/client.c.
998 * The sender of the file transfer request now provides also
999 the pointer (listener) for the key exchange protocol. If
1000 the listener cannot be created then it sends empty key
1001 agreement and lets the receiver provide the listener.
1003 Added `local_ip' and `local_port' arguments to the
1004 silc_client_file_send. If they are provided they are used,
1005 if not then it will attempt to find local IP address, if
1006 not found or bind fails then the remote client will provide
1009 Affected files are lib/silcclient/client_ftp.c and
1010 lib/silcclient/silcapi.h.
1012 * Extended the FILE SEND command to support defining the
1013 local IP and port for key exchange listener. They are
1014 optional. Affected file irssi/src/silc/core/silc-servers.c.
1016 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Defined to WHOIS command reply the sending of fingerprint
1019 of the client's public key (if the proof of posession of the
1020 corresponding private key is verified by the server).
1021 Updated to the protocol specification.
1023 * Added support of receiving the client's public key's
1024 fingerprint in command reply in client library. Affected
1025 file is lib/silcclient/command_reply.c, and
1026 lib/silcclient/idlist.[ch].
1028 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1030 * Do not send over 128 chars long nickname to the server
1031 in NICK command. Affected file lib/silcclient/command.c.
1033 * Do not send over 256 chars long channel names to the server
1034 in JOIN command. Affected file lib/silcclient/command.c.
1036 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1038 * Assure that silc_server_close_connection cannot be called
1039 twice for same socket context. Affected file is
1042 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Send error message to application if opening file for
1045 writing during file transfer fails. Affected file is
1046 lib/silcclient/client_ftp.c.
1048 Remove all file transfer sessions for a client that we're
1049 removing from ID cache.
1051 Affected file is lib/silcclient/client_ftp.c.
1053 * Fixed silc_net_addr2bin to return correct address. Affected
1054 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1056 * Fixed file transfer session removing on signoff notify.
1057 Affected file irssi/src/silc/core/silc-servers.c.
1059 * Added the SilcClientFileError to be returned in the monitor
1060 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1061 Affected file lib/silcclient/silcapi.h.
1063 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Fixed a crash in silc_client_ftp_free_sessions and
1066 silc_client_ftp_session_free_client. Affected file
1067 lib/silcclient/client_ftp.c.
1069 * Added `disabled' field in the SilcChannelEntry in the server
1070 to indicate if the server entry is disabled. Affected file
1071 silcd/idlist.h, silcd/command[_reply].c.
1073 * SILC server adds now /var/run/silcd.pid everytime it is
1074 started. Affected file silcd/silcd.c.
1076 * Added silc_server_packet_send_clients to send a packet to
1077 the provided table of client entries. Affected file
1078 silcd/packet_send.[ch].
1080 * Fixed a crash in client resolving in client_prvmsg.c in
1081 client library. Affected file lib/silcclient/client_prvmsg.c.
1083 * Do not actually remove the client directly from ID cache
1084 during SERVER_SIGNOFF, but invalidate it. This way we
1085 preserve the WHOWAS info for the client. Affected file
1086 silcd/server_util.c.
1088 * Fixed SERVER_SIGNOFF notify handling in the server. The
1089 server is now able to process incoming SERVER_SIGNOFF notify
1090 for a server that it doesn't even know about. It will remove
1091 the clients provided in the notify. Affected file
1092 silcd/packet_receive.c.
1094 * Check for partial packet in data queue after every packet that
1095 was found from the queue. Return and wait for more data if
1096 there is partial data in queue. Affected file is
1097 lib/silccore/silcpacket.c.
1099 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Added SilcClietFileError enum to indicate error in
1102 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1103 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.

1105 lib/silcclient/client_ftp.c.
1107 * Check that newsize in silc_buffer_realloc is larger than
1108 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1110 * Added better monitor of file transfers. It now monitors
1111 key agreement protocol during the file transfer too. Added
1112 error reporting too. Affected files
1113 irssi/src/silc/core/silc-servers.c,
1114 irssi/src/fe-common/silc/module-formats.[ch].
1116 * Wrote a help file for FILE command.
1118 * Added silc_rng_global_get_byte_fast to get not-so-secure
1119 random data as fast as possible. Random data is read from
1120 /dev/urandom if available and from the SILC RNG if not
1121 available. It is used in padding generation. Affected file
1122 lib/silccrypt/silcrng.[ch].
1124 * All packets in client library are now processed synchronously.
1125 Optimized packet processing a lot. Affected file
1126 lib/silcclient/client.c.

1129 now in server, to optimize packet processing. Affected file
1132 * Include files are installed now only in Toolkit distribution
1133 if make install is given. Affected files: all Makefile.am's.
1135 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1137 * Assure that silc_client_notify_by_server_resolve does not
1138 resolve the client information multiple times. If it cannot
1139 be found by the first it cannot be found at all. Affected
1140 file lib/silcclient/client_notify.c.
1142 * Fixed WHOWAS command reply calling. Affected file
1143 lib/silcclient/command_reply.c.
1145 * Removed all references to silc_idlist_get_client from the
1146 Irssi SILC client since that call is internal call used by
1147 the library. The Irssi SILC client will use now client
1148 retrieval functions found in silcapi.h.
1150 * Fixed a bug in resolving nickname info before sending
1151 private message. It used freed memory. Affected file
1152 irssi/src/silc/core/silc-servers.c.
1154 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1156 * Assure my_channels statistics cannot go negative in server.
1157 Affected files silcd/server.c, silcd/server_util.c.
1159 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1173 * Added silc_net_localip to return local host's IP address.
1174 Affected file lib/silcutil/silcnet.[ch].
1176 * If key exchange or rekey protocol is active for a connection
1177 parse all packets syncronously since there might be packets
1178 in packet queue that we are not able to process without first
1179 processing packets before them. Affected file silcd/server,
1180 lib/silcclient/client.c.
1182 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1183 whether library should continue processing the packet.
1184 Affected file lib/silccore/silcpacket.h.
1186 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1215 lib/silcutil/silcutil.[ch].
1217 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Resolve the client info when received private message or
1220 channel message for a client which nickname we don't know.
1221 Affected files lib/silcclient/client_prvmsg.c and
1222 lib/silcclient/client_channel.c.
1224 * Do not crash in /KEY if client is not connected. Affected
1225 file irssi/src/silc/core/silc-channels.c.
1227 * Added SilcClientStatus field to the SilcClientEntry in the
1228 lib/silcclient/idlist.h.
1230 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1231 is incomplete and is being resolved, it won't be resolved
1234 Make sure also that USERS command reply does not resolve
1235 twice information. Affected file is
1236 lib/silcclient/command_reply.c.
1238 Make sure that silc_client_get_clients_by_list does not
1239 resolve twice same information.
1241 * Check for valid client->id in the silc_server_free_client_data.
1242 Affected file silcd/server.c.
1244 * Fixed /GETKEY nick@server not to crash if the server entry
1245 is not found. Affected file lib/silcclient/command.c.
1247 * Fixed the silc_server_check_cmode_rights to check the
1248 requested modes correctly. Affected file silcd/command.c.

1252 * Better checks for non-printable chars in nick added.
1253 Affected file silcd/command.c.
1255 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Call the silc_server_udpate_servers_by_server in the
1258 primary router that comes back online in the backup resuming
1259 protocol. Otherwise it routes packets wrong. Affected file
1260 silcd/server_util.[ch], silcd/server_backup.c.
1262 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1264 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1265 lib/silcutil/silcbuffmt.[ch].
1267 * Redefined the SILC packet header to include the padding
1268 length. Affected file lib/silccore/silcpacket.[ch].
1270 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1271 length for maximum padding up to 128 bytes). Affected
1272 file lib/silccore/silcpacket.h.
1274 * Removed all backwards support for old 0.5.x MAC thingies.
1275 The SILC packet header change makes it impossible to be
1276 backwards compatible.
1278 * Send the ENDING packet with timeout in the backup resuming
1279 protocol. This is to assure that all routers has connected
1280 to the primary router. Affected file silcd/server_backup.c.
1282 * Changed the RNG to take the first IV from random data. It
1283 used to take it from zero actually. Changed the RNG also
1284 to use /dev/urandom during session. /dev/random is used
1285 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1287 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Changed the SILC packet header to have the first two bytes
1290 (the packet length) encrypted. Affected files aroung the
1291 code tree, lib/silccore/silcpacket.[ch]. Removed the
1292 SilcPacketCheckDecrypt callback. It is not needed anymore
1293 since the silc_packet_receive_process will determine now
1294 whether the packet is normal or special.
1296 * Implemented the unidirectional MAC keys. Affected files
1297 lib/silcske/silcske.c, silcd/protocol.c and
1298 lib/silcclient/protocol.c.
1300 * Implemented the packet sequence number to the MAC computation.
1301 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1302 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1303 lib/silcclient/protocol.c.
1305 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Allow backup router to announce servers. All servers
1308 announced by backup router are added to the global list
1309 automatically. Update hte server's socket to our primary
1310 router also when backup router announces a server.
1311 Affected file silcd/packet_receive.c.
1313 * Do not update the client->router in the function
1314 silc_server_udpate_clients_by_server if the client is on
1315 global list. We might fail to find any specific server
1316 for locally connected clients and local cell clients. They
1317 should still use the `from' and not `to' as client->router.
1318 This fixes backup router resuming protocol. Affected file
1319 silcd/server_util.c.
1321 * Decrease channel statistics count only if the channel
1322 deletion worked. Affected files are silcd/server.c and
1323 silcd/server_util.c.
1325 * Added silc_server_update_servers_by_server to update origin
1326 of all server entries. Used during backup router protocol.
1327 Affected files silcd/server_util.[ch], silcd/server.c. and
1328 silcd/backup_router.c.
1330 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1331 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1332 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1333 lib/silccrypt/silchmac.c.
1335 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Assure that router cannot reroute the same channel message
1338 to the sender. Affected file silcd/packet_receive.c.
1340 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Made better checks that the channel message is not sent
1343 to the router it came from. Affected file is
1344 silcd/packet_send.c. Fixed memory leak too.
1346 * Announce informations for incoming router connection, but
1347 only after checking if it is replaced by backup router.
1348 Affected file silcd/packet_receive.c.
1350 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Fixed the backup resuming protocol to work in multiple
1353 router environment. Affected file silcd/server_backup.c.
1355 * Route packet only to one router in the function
1356 silc_server_packet_send_to_channel. Affected file is
1357 silcd/packet_send.c.
1359 * Fixed silc_server_send_notify_dest to set the broadcast
1360 flag. Fixed the silc_server_send_notify_topic to actually
1361 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1362 Affected file silcd/packet_send.c.
1364 * Changed the SFTP Filesystem interface. Changed the
1365 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1366 the filesystem operation function. The SilcSFTPFilesystem
1367 is now a context that is allocated by all filesystem allocation
1368 functions and it already includes the operations structure
1369 and filesystem specific context. It is given as argument
1370 now to the silc_sftp_server_start. This made the interface
1371 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1372 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1374 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1376 * Changed the backup router adding and getting interfaces
1377 in the server. The router that will be replaced by the
1378 specified backup router is now sent as argument. Affected
1379 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1382 * Added silc_net_addr2bin_ne to return the binary form of
1383 the IP address in network byte order. Affected files
1384 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1386 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Check for existing server ID in silc_server_new_server
1389 and in silc_server_connect_to_router_final and remove the
1390 old entry if it exists. Affected file silcd/packet_receive.c,
1393 * Send the channel message always to only one router, either
1394 in upstream or downstream. Affected file is
1395 silcd/packet_send.c.
1397 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Wrote the definition of the backup resuming protocol to the
1400 protocol specification.
1402 * Removed one redundant channel key generation from normal
1403 server during joining procedure. Removed one redundant
1404 channel key sending from server to router during joining
1405 procedure. Affected file silcd/command.c.
1407 * Made minor bugfixes to the backup router resuming protocol.
1408 Affected file silcd/server_backup.c, server.c.

1413 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1416 * Implemented the backup resuming protocol that is used to
1417 resume the primary router position in the cell after the
1418 primary router comes back online. Affected files
1419 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1420 and silcd/server_util.[ch].
1422 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * Sleep two (2) seconds after sending QUIT command to server.
1425 Affected file lib/silcclient/command.c.
1427 * Assure that if outgoing data buffer is pending do not force
1428 send any data. Affected file silcd/packet_send.c.
1430 * Assure that if outgoing data buffer is pending do not force
1431 send any data. Affected file lib/silcclient/client.c.
1433 * Implemented the backup router support when the primary router
1434 goes down. The servers and routers can now use the backup
1435 router as new primary router without loosing connectivity.
1437 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1440 in the server to indicate disabled entry. All data read
1441 from the connection will be ignored and no data is sent
1442 for entry that is disabled. Affected files are
1443 silcd/idlist.h, silcd/server.c.
1445 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Created SFTP client and server test programs in the
1448 lib/silcsftp/tests directory.
1450 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Implemented memory filesystem (virtual filesystem) for
1453 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1456 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Implemented the SFTP (SSH File Transfer Protocol) to the
1459 lib/silcsftp. It includes SFTP client and SFTP server
1462 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Moved lib/silccore/silcprotocol.[ch] to the
1465 lib/silcutil library.
1467 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1468 take variable argument list pointer as argument. Affected
1469 file lib/silcutil/silcbuffmt.[ch].
1471 * Added silc_buffer_set function that is used to set data
1472 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1473 Affected file lib/silcutil/silcbuffer.h.
1475 * Changed various routines in the core library to use the new
1476 silc_buffer_set instead of allocating new buffer only for
1479 * Added 64-bit value formatting and unformatting support to the
1480 silc_buffer_[un]format routines. Affected file is
1481 lib/silcutil/silcbuffmt.[ch].
1483 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1484 to includes/bitmove.h.
1486 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Fixed channel user mode saving in client library. Affected
1489 file lib/silcclient/command[_reply].c.
1491 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Defined the file transfer to the SILC Protocol. Added
1494 new packet type SILC_PACKET_FTP and defined File Transfer
1495 Payload. The mandatory file transfer protocol is SFTP
1496 (SSH File Transfer Protocol). Affected file in addition
1497 of the internet draft is lib/silccore/silcpacket.h.
1499 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1500 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1501 is used as part of backup router protocol when the primary
1502 router of the cell is back online and wishes to resume
1503 the position as primary router.
1505 * Redefined the MAC generation keys in the protocol. The
1506 same key is not used anymore in both direction. Both
1507 direction will now use different keys for sending and
1508 receiving. This fixes a potential security flaw. This
1509 change causes incompatibilities in the protocol.
1511 * Redefined also the MAC computation from the packet.
1512 An packet sequence number is now added to the MAC
1513 computation. This prevents possible replay attacks against
1514 the protocol. This change too causes incompatibilities
1517 Added `sequence' field to the SilcPacketContext to hold
1518 the current sequence number for the packet.
1520 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1522 * Added `created' field to the SilcIDListData in the file
1523 silcd/idlist.h to indicate the time when the entry was
1526 * Added `created' field to the SilcChannelEntry too. Affected
1527 file silcd/idlist.h.
1529 * Added `creation_time' aguments to all the announcement functions
1530 in the server. If it is provided then only the entries that
1531 was created after the provided time frame are actually
1532 announced. Affected file silcd/server.[ch].
1534 * The protocol says that the Channel ID's IP address must be
1535 based on the router's IP address. Added check for this in
1536 the silc_server_new_channel when processing incoming New Channel
1537 Payload. Affected file silcd/packet_receive.c.
1539 * Print out the correct version with --version in SILC client.
1540 Affected file irssi/src/silc/core/silc-core.c.
1542 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Fixed WHOWAS command to check for completnes of the client
1545 entry always, not just when the command is coming from client.
1546 Affected file silcd/command.c.
1548 * Added new function silc_server_packet_queue_purge to purge the
1549 outgoing data queue to the network. After the function returns
1550 it is guaranteed that the outgoing packet queue is empty.
1551 Affected file silcd/packet_send.[ch].
1553 * Purge the outgoing packet queue in the rekey protocol's final
1554 callback to assure that all rekey packets go to the network
1555 before quitting the protocol. Affected file silcd/server.c.
1557 * Added silc_client_packet_queue_parse as similar function as
1558 in server to the client library. The affected file is
1559 lib/silcclient/client.c.
1561 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1563 * Splitted silcd/server.c and created silcd/server_util.[ch]
1564 for utility functions.
1566 * Added new socket flag SILC_SF_DISABLED to indicate that the
1567 connection is open but nothing can be sent to or received from
1568 the connection. Affected file lib/silcutil/silsockconn.[ch].
1569 The checking for disabled socket is checked in the low level
1570 silc_socket_write and silc_socket_read functions.
1572 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Allow only nicknames and channel names that fits into the
1575 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1577 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * When processing JOIN command reply in server check that if
1580 the channel exists in our global list we'll move it the local
1581 list. Affected file silcd/command_reply.c.
1583 * Fixed the check whether client is joined on the channel already
1584 in JOIN command. Affected file lib/silcclient/command.c.
1586 * Fixed the JOIN command reply to check whether the channel
1587 already exists. Affected file lib/silcclient/command_reply.c.
1589 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Added silc_ske_status_string to map the SKE error numbers
1592 to readable strings. The affected files are
1593 lib/silcske/silcske[_status].[ch].
1595 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Do not show the private channels on the WHOIS channel list
1598 as it is not allowed by the protocol. The affected file is
1601 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * Assure that the packet length digged from the actual packet
1604 is something sensible in the silc_packet_decrypt_rest_special
1605 in lib/silccrypt/silcpacket.c.
1607 * Free and NULL the allocated pointer in silc_hmac_alloc if
1608 the HMAC allocation fails. The affected file is
1609 lib/silccrypt/silchmac.c.
1611 * Print the selected security properties to the log files in
1612 the server. Affected file silcd/protocol.c.
1614 * Add SKE's reference counter even if calling the completion
1615 callback manually. Otherwise it goes negative, although it
1616 does not cause any problems. The affected file is
1617 lib/silcske/silcske.c.
1619 * Remove the client entry with short timeout after giving the
1620 KILL command. Affected file lib/silcclient/command.c.
1622 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1623 case all found clients are already disconnected (WHOWAS would
1624 found them) in the server. Affected file silcd/command.c.
1626 * Update the last_receive (time of last data received) to be
1627 updated only when received private or channel message so that
1628 the idle time showed in WHOIS makes more sense.
1630 * Added boolean field `valid' in to the SilcClientEntry in the
1631 client library to indicate whether the entry is valid or not.
1632 This fixes the nickname change bug on channel when changing
1633 the nickname to be same than the old (like nick to Nick) the
1634 nickname formatter doesn't set the new nick anymore to Nick@host.
1635 Affected file lib/silcclient/idlist.[ch].
1637 * Now actually fixed the nickname changing on disconnection.
1638 Added new function silc_change_nick to the Irssi SILC Client.
1639 Affected file irssi/src/silc/core/client_ops.c,
1640 irssi/src/silc/core/silc-nicklist.[ch].
1642 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Check that the public key exists in the GETKEY command before
1645 trying to encode it. Affected file silcd/command.c.
1647 * Print some notifications on received public keys with GETKEY
1648 command in the Irssi SILC Client. Affected files are
1649 irssi/src/fe-common/silc/module-formats.[ch],
1650 irssi/src/silc/core/client_ops.c.
1652 * Use IDENTIFY command to resolve the server information in the
1653 GETKEY command instead of INFO command. Affected file
1654 lib/silcclient/command.c.
1656 * All command reply functions in the client library now calls
1657 the pending command reply callbacks even if an error has
1658 occurred. The server has done this a long time and now it was
1659 time to move the client library to this as well. Now all
1660 errors can be delivered back to the pending command reply
1661 callbacks if necessary. Affected files are
1662 lib/silcclient/command[_reply].[ch].
1664 * Change the nickname on disconnection back to the username
1665 because in reconnect the server will enforce it to it anyway.
1666 Affected file irssi/src/silc/core/silc-servers.c.
1668 * Fixed a config file parsing bug in the Irssi SILC client.
1669 Affected file irssi/src/silc/core/clientconfig.c.
1671 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1673 * When printing the channel mode on JOIN, verify that the
1674 channel key and channel's HMAC are valid. Affected file
1675 irssi/src/silc/core/client_ops.c.
1677 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1680 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1681 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1683 * Removed channel key rekey task deleting from the function
1684 silc_server_save_channel_key. Affected file silcd/server.c.
1685 Added explicit timeout task context instead that is used to
1686 delete the task if we are registering a new task before the
1687 new task has elapsed.
1689 * When channel key rekey occurs the client library now saves
1690 the old channel key for a short period of time (10 seconds) and
1691 is able to use it in case some is still sending channel
1692 messages encrypted with the old key after the rekey. Affected
1693 file lib/silcclient/[idlist.h|client_channel.c].
1695 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Added check to the silc_server_new_id_real to not accept
1698 new ID if it is the sender's own ID. Affected file is
1699 silcd/packet_receive.c.
1701 * Assure that we do not announce ourself or the one we've
1702 sending our announcements when we're router and are announcing
1703 servers to our primary router. Affected file silcd/server.c.
1705 * Fixed silc_server_command_identify_check_client to assemble
1706 correct WHOIS packet. It send corrupted WHOIS packet and
1707 caused problem with router to router connections. Affected
1708 file silcd/command.c.
1710 Fixed also silc_server_command_whois_check the same way
1711 as for the IDENTIFY command.
1713 * Added new SilcIDListStatus to the server in the SilcIDListData
1714 structure. The status now includes the current status of
1715 the entry (like registered, resolved etc.). Affected file
1716 silcd/idlist.[ch]. Defined a bunch of different status types
1717 as well. This replaced the old boolean registered field as well.
1719 Added resolve_cmd_ident field to the SilcClientEntry structure
1720 too so that if the entry is for example being resolved so
1721 another command may attach to the same pending command reply
1722 without requiring to resolve the same entry again. This concept
1723 should optimize the WHOIS and the IDENTIFY resolving under
1724 heavy load by taking away unnecessary resolving for entries
1725 that are being resolved already.
1727 Added support for adding multiple pending commands for one
1728 command idenfier. Affected file silcd/command[_reply].[ch].
1730 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1731 before deleting the data. Otherwise the hash table will have
1732 freed data in comparison functions. Affected file is
1733 silcd/command_reply.c.
1735 * Fixed silc_idlist_replace_client_id to add the new entry to
1736 the cache with NULL nickname. Otherwise there will be invalid
1737 memory as the nickname after the nickname is freed. Affected
1738 file silcd/packet_receive.c.
1740 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1741 saved into wrong slots because the previous number of entries
1742 was not taken into account. Affected file silcd/idlist.c.
1743 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1745 * If we are router and we receive JOIN notify to a channel that
1746 does not have any users then notified client is marked as the
1747 channel founder, as it is it. The affected file is
1748 silcd/packet_receive.c
1750 * Added to the extended hash table API's table_del_*ext functions
1751 the destructor as argument too, so that the caller can decide
1752 which destructor to use or whether to use destructor at all.
1753 Affected file lib/silcutil/silchashtable.[ch].
1755 * Fixed ID Cache purging. It actually deleted the entries from
1756 the hash table after the data was freed. The hash table ended
1757 up comparing freed memory. The affected file is
1758 lib/silccore/silcidcache.c.
1760 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Fixed Irssi SILC client's KILL command's HELP syntax.
1764 * The USERS command now resolves the detailed user information
1765 if the userinfo field is missing. Affected file is
1766 lib/silcclient/command_reply.c.
1768 * Do not print error in silc_file_read if the read file does
1769 not exist. Just silently return NULL. Affected file is
1770 lib/silcutil/silcutil.c.
1772 * Fixed the silc_log_output to not wine about NULL filename
1773 and to not create some bogus " " filename. Affected file is
1774 lib/silcutil/silclog.c.
1776 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Fixed various printing bugs on the user interface in the
1779 Irssi SILC Client. Minor changes that were forgotten from
1782 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Fixed the configure.in.pre and the compilation and distribution
1785 environment to support the new autoconf 2.52. That version is
1786 now required to compile the CVS trunk.
1788 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1791 to generally parse user@fqdn format strings. Affected file
1792 lib/silcutil/silcutil.c.
1794 * Added nickname_format and nickname_force_format fields to the
1795 SilcClientParams structure. The first one defines the format
1796 for the nicknames that the library will enforce if the receives
1797 multiple same nicknames. The second one is boolean value and
1798 can be used to force the library to always enforce the format
1799 to the nicknames regardles whether there are multiple nicknames
1800 or not. This configurable formatting was employed to flexibly
1801 support accessing multiple nicknames from the user interface.
1802 The userinterface can now set the nicknames to what ever format
1803 they prefer. Affected file lib/silcclient/silcapi.h.
1805 Added function silc_client_nickname_format to the file
1806 lib/silcclient/idlist.c. It performs the nickname formatting.
1808 Added new field `hostname´ to the SilcClientEntry context.
1809 It holds the hostname of the client. Affected file is
1810 lib/silcclient/idlist.h.
1812 * Irssi SILC Client sets the nicknames in nick@hostn format.
1813 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1814 irssi/src/silc/core/silc-core.c.
1816 The WHOIS printing now also shows both the real nickname and
1817 the formatted nickname so that user knows how to access the
1818 user if there are multiple same nicknames cached. Affected
1819 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1820 printing formatting too to take the hostname now as a separate
1821 argument. The Affected file is
1822 irssi/src/fe-common/silc/modules-formats.[ch].
1824 * Changed the silc_client_get_clients_local to accept the formatted
1825 nickname as argument. It accepts the real nickname too but the
1826 formatted nickname can be used to find the true entry from
1827 multiple entries. Affected file lib/silcclient/silcapi.h and
1828 lib/silcclient/idlist.c.
1830 * Added nickname_format_parse field to the SilcClientParams.
1831 It is a callback function provided by the application to parse
1832 the nickname out of the formatted nickname string. The library
1833 calls it to get the nickname from the formatted string. Since
1834 the application generally knows better the format of the nickname
1835 string it parses it instead of the library, even though library
1836 encodes the formatted string. If the callback function is not
1837 provided then the library will use the string as is. The
1838 affected file is lib/silcclient/silcapi.h.
1840 * All the nickname strings passed to the client library in
1841 commands are now expected to be formatted nickname strings.
1842 If the command does not support the formatted nickname string
1843 it will assume that the sent string is the actual nickname.
1844 Affected file lib/silcclient/command.c.
1846 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Added public key authentication support to OPER and SILCOPER
1849 commands in the client library. Affected file is
1850 lib/silcclient/command.c.
1852 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Changed the get_auth_methdod client operation to be asynchronous.
1855 It can be async if the application resolves the authentication
1856 method from the server during the negotiation. Added new
1857 SilcGetAuthMeth completion callback that the application will
1858 call after resolving the authentication method.
1860 Added function silc_client_request_authentication_method that
1861 the application can use to resolve the authentication method
1862 from the server. Added also SilcConnectionAuthRequest callback
1863 that the library will call after the server has replied. The
1864 application can call this function if it does not know the
1865 current authentication method.
1867 Affected files are lib/silcclient/client.c and
1868 lib/silcclient/silcapi.h.
1870 * The Irssi SILC client now automatically resolves the authentication
1871 method incase any configuration information is not present (and
1872 currently there never is). The affected file is
1873 irssi/src/silc/core/client_ops.c.
1875 * Fixed public key authentication from the client library.
1876 Affected file lib/silcclient/protocol.c. Changed also the
1877 protocol specification about the public key authentication in
1878 the connection authentication protocol. The actual data to be
1879 signed is now computed with a hash function before signing.
1881 * Fixed the public key authentication from the server as well.
1882 Affected file silcd/protocol.c.
1884 * Removed the mlock()'s from the memory allocation routines.
1885 Affected file lib/silcutil/silcmemory.c. The ./configure does
1886 not check anymore for the mlock(). Affected file is
1889 * Fixed USERS command in server to allow the execution of the
1890 command for private and secret channels if the client sending
1891 the command is on the channel. Affected file silcd/command.c.
1893 * Fixed silc_client_get_clients_local to return the clients
1894 count correctly. It could return wrong value. Affected file
1895 lib/silcclient/idlist.c.
1897 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1900 types. The assembler optimizations seemed not to like 64-bit
1901 data types. The assmebler optimizations thus are now enabled
1902 also for BSD systems as opposed to only enable them for Linux.
1904 * Do not check for threads at all on BSD systems. Affected
1905 file configure.in.pre.
1907 * Removed -n and -h options from the Irssi SILC Client since
1908 they are not used in silc.
1910 * Fixed the prime generation to assure that the first digit
1911 of the generated random number is not zero since our conversion
1912 routines does not like number strings that starts with zero
1913 digit. If zero digit is seen the random number is regenerated.
1914 This caused some corrupted RSA keys when the zero first digit
1915 was met. Affected file lib/silcmath/silcprimegen.c.
1917 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Fixed WIN32 configuration in the ./configure script.
1920 Fixed to include xti.h on environments that has it.
1921 Patches by Carsten Ilchmann and andrew.
1923 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Changed the silc_id_create_client_id to be collision
1926 resistant. It is now assured that there cannot be created
1927 two same client ID's. I suspect that some weird bugs in
1928 the server were actually caused by duplicate Client IDs.
1929 Affected file silcd/serverid.[ch]. A router receiving
1930 new ID now also assures and informs the sending server
1931 if the ID caused collision.
1933 * Changed the silc_id_create_channel_id to also assure that
1934 there are no collisions.
1936 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Statement about ignoring the Mutual Authentication flag when
1939 performing rekey with PFS was a bit misleading. It is ignored
1940 if it was set in the initial negotiation, it cannot be even
1941 set in the rekey. Fixed in the ke-auth draft. Started the
1942 new versions of the protocol drafts in the doc/.
1944 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Fixed a bug in silc_client_command_identify_save when saving
1947 new channel information. The channel name was no duplicated
1948 and caused crash on exit. Affected file is
1949 lib/silcclient/command_reply.c.
1951 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Fixed the getkey command handling in the server. Send just
1954 empty OK reply to the sender if the key could not be fetched
1955 (but everything else was ok, like the key just was not available).
1956 Changed the public key parameter to optional in the protocol
1957 specs so that empty OK reply can be sent. Affected file
1960 Added a message to Irssi SILC client to tell to user if the
1961 server did not return a public key.
1963 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Fixed a channel key regeneration bug. It registered new
1966 timeout tasks exponentially until all system resources were
1967 used. Affected file silcd/server.c.
1969 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Added the SILC Document generator to the scripts/silcdoc.
1972 It can be used to generate the Toolkit Reference Manual out
1973 of the source tree. Internally it will also use the RoboDoc
1974 generator now imported in util/robodoc.
1976 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1978 * Added couple of return's in rekey protocol if error orccurred
1979 during the protocol. The execution must be terminated.
1980 Affected file silcd/protocol.c. Also, terminate the protocol
1981 always with timeout.
1983 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * The client's Client ID was created initally from the wrong
1986 nickname (it could have been in format nick@host) in the
1987 silc_server_new_client. Affected file silcd/packet_receive.c
1989 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Added some SILC_LOG_ERROR's to various error conditions
1992 if client could not be added to ID cache. Affected files
1993 silcd/packet_receive.c and silcd/server.c.
1995 * When client's sock->user_data is freed, NULL also the
1996 client->router and client->connection pointers. Added check
1997 for these pointers being NULL to various places around the
1998 code. Affected file silcd/server.c.
2000 * Added client->data.registered == TRUE checks to various
2001 places around the code to assure that unregistered client's
2002 are not handled when it is not allowed. Affected file
2005 * Added `bool registered' fields to all
2006 silc_idlist_[server|client]_get_* routines to indicate whether
2007 the fetched client needs to be registered or not. Affected
2008 file silcd/idlist.[ch].
2010 * Add your own entry as registered to the ID cache in the
2011 server. Affected file server.c.
2013 * Fixed a bug in silc_server_new_server. The SilcServer was
2014 set as the new server's context instead of SilcServerEntry.
2015 This naturally caused some weird bugs.
2017 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * Do not delete the channel rekey task when adding it
2020 for in silc_server_create_channel_key.
2022 * Changed the silc_server_create_channel_key to return
2023 TRUE or FALSE to indicate the success of the channel key
2026 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Fixed MSVC++ project files and added missing files to
2029 Makefiles under win32/.
2031 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Do not add TCP_NODELAY flag if the operating system
2034 does not have it defined. Affected files are
2035 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2037 * Fixed buffer overflow from Irssi SILC Client. Affected
2038 file irssi/src/fe-common/core/themes.c.
2040 * Fixed double free in client library in the file
2041 lib/silcclient/client.c when disconnecting from server.
2043 * Applied double free patch from cras to Irssi SILC client.
2044 Affected files irssi/src/core/[modules/expandos].c
2046 * Fixed the disconnection handling to Irssi SILC Client.
2047 The application must call silc_client_close_connection
2048 in ops->connect client operation in case of failure of
2049 the connection. Affected file is
2050 irssi/src/silc/core/client_ops.c.
2052 * Do not set sock->protocol to NULL in the function
2053 silc_client_close_connection after executing the protocol's
2054 final callback since the sock might not be valid anymore.
2055 Affected file lib/silcclient/client.c.
2057 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2059 * Do not enable SILC_THREADS if the linking with libpthread
2060 did not happen. Affected file configure.in.pre.
2062 * Added notion to protocol specification that server must
2063 verify the sent authentication payload with CMODE when
2064 setting the channel founder key. Implemented it to the
2065 server. Affected file silcd/command.c.
2067 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Added _EXTRA_DIST SILC distribution variable to the
2070 distributions file. It is used to conditionally add extra
2071 files or directories to the specific distribution. Affected
2072 files ./prepare, Makefile.am.pre and distributions.
2074 Removed the `_' from the start of the distribution names.
2077 * Added README.WIN32 for instructions to compile the Toolkit
2080 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Fixed a double free in disconnection in the server. Affected
2083 file is silcd/server.c.
2085 * Fixed the lib/silcske/groups.c to work now also with GMP
2086 MP library. The string conversion did not work when using
2087 specific base and the base is indicated in the string as well.
2089 * Created win32/ directory which now includes MSVC++ specific
2090 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2091 It will appear only in the toolkit distribution
2093 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Changed the key material distribution function in case when
2096 the hash output is too short. The data is now concatenated
2097 a bit differently than it used to. Made the change to the
2098 SKE protocol specification.
2100 * Added better GMP detection to configure.in.pre. A patch
2103 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Fixed a minor bug in SKE that might cause some problem on
2106 some platforms. Affected file lib/silcske/silcske.c.
2108 * Added the cookie checking for initiator in the SKE. It checks
2109 that the responder returns the sent cookie unmodified. The
2110 affected file is lib/silcske/silcske.c. Added new SKE
2111 error type INVALID_COOKIE that can be sent during the
2112 negotiation. Fixed some memory leaks as well.
2114 * Added the "invalid cookie" error message to Irssi SILC client's
2117 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Added `task_max' field to the SilcClientParams to indicate
2120 the maximum tasks the scheduler can handle. If set to zero,
2121 default values are used. Affected file lib/silcclient/silcapi.h.
2123 * Fixed memory leaks in silc_client_close_connection. Affected
2124 file lib/silcclient/client.c.
2126 * Added silc_client_del_client_entry to client library to free
2127 all memory of given client entry. Affected file is
2128 lib/silcclient/idlist.[ch].
2130 * Added new functions silc_client_del_channel and
2131 silc_client_del_server to delete channel and server entries.
2132 Affected file lib/silcclient/[silcapi.h/idlist.c].
2134 * Removed silc_client_del_client_by_id from silcapi.h.
2136 * Fixed the INFO command to return the server's own info
2137 correctly when querying by Server ID. Affected file is
2140 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2142 * Removed the non-blocking settings in WIN32 code in the
2143 silc_sock_[read/write] and added SleepEx instead. Affected
2144 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2145 of input data is now checked with FIONREAD and ioctlsocket.
2147 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2149 * Call silc_schedule_task_del_by_context in the
2150 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2151 Affected file lib/silccore/silcprotocol.c.
2153 * Call silc_protocol_cancel for active protocols in the
2154 silc_server_close_connection if the funtion
2155 silc_server_free_sock_user_data has not been called.
2156 Affected file silcd/server.c.
2158 * Generic tasks cannot be deleted using the del_by_fd
2159 task deleting function since generic tasks does not match
2160 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2162 * Added a notion to SILCOPER help file that the SILCOPER works
2163 only on router server, not on normal server.
2165 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Added for WIN32 support for the new scheduler as well.
2168 Affected file lib/silcutil/win32/silcwin32schedule.c.
2170 * Fixed the SHA1 implementation to work on various platforms.
2172 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2175 API. It is part of the scheduler now. Everything else is
2176 as previously but some functions has changed their names.
2177 Checkout the lib/silcutil/silcschedule.h for the interface.
2178 Updated all applications to use the new interface. Affected
2179 files are lib/silcutil/silcschedule.[ch].
2181 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Found a bug in the SKE implementation. The HASH value,
2184 specified by the protocol, was not computed correctly. The
2185 public key of the responder was not added to the computation
2186 even though it is mandatory. Affected file lib/silcske/silcske.c.
2187 This unfortunately causes incompatibilities with older
2188 clients and servers.
2190 * Added WIN32 specific network init and uninit functions:
2191 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2192 the Winsock2. Affected file lib/silcutil/silcnet.h and
2193 lib/silcutil/win32/silcwin32net.c.
2195 * Set the socket always to nonblocking mode on WIN32 after
2196 reading data or writing data. Affected file is
2197 lib/silcutil/win32/silcwin32sockconn.c.
2199 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2201 * Fixed various compilation problems under WIN32. Affected
2202 files lib/silcutil/win32/silcwin32thread.c and
2203 lib/silcutil/win32/silcwin32schedule.c.
2205 * Removed all _internal.h #includes from public header
2206 files. Internal headers must never be included from
2209 Removed also the lib/silcske/payload_internal.h file.
2211 * All include files that may be needed (public and some others
2212 included by the public headers) by application developers are
2213 now copied to the ./includes directory. It does not copy any
2214 internal headers. Affected file Makefile.defines.pre and all
2215 Makefile.am's under lib/ and subdirs.
2217 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Do not change the ~/.silc directory's permissions automatically.
2220 Affected file irssi/src/silc/core/clientutil.c.
2222 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Do not cancel the protocol in silc_server_close_connection
2225 it might cause recursion. Now cancelled in the function
2226 silc_server_free_sock_user_data. Affected file silcd/server.c.
2228 * Fixed the silc_server_remove_clients_by_server to regenerate
2229 the channel keys correctly finally. Added also new function
2230 silc_server_remove_clients_channels to actually do it.
2231 Affected file silcd/server.c.
2233 * Fixed the silc_server_new_channel to not crash by giving
2234 wrong router to the new channel. Affected file is
2235 silcd/packet_receive.c.
2237 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2240 which is given as argument to the silc_client_alloc now.
2241 It can be used to configure the client and set various parameters
2242 that affect the function of the client.
2244 * The USERS command in server did not check whether the channel
2245 is private or secret. Affected file silcd/command.c.
2247 * Added new argument to the USERS command in protocol specification.
2248 The USERS command now can take the channel name as argument
2249 as well. Added support for this in client and server and
2250 updated the protocol specs.
2252 * Completed the GETKEY command in client. It can be now used
2253 to fetch also servers public key not only some clients.
2254 Affected files lib/silcclient/command[_reply].c.
2256 * Added silc_client_get_server to return server entry by the
2257 server name. Affected files lib/silcclient/silcapi.h and
2260 * Redefined the IDENTIFY command in protocol specification to be
2261 more generic. It now can be used to query information about
2262 any entity in the SILC Network, including clients, servers and
2263 channels. The query may be based either the entity's name
2264 or the ID. Added support for this in both client and server.
2266 Affected files silcd/command.c and lib/silcclient/command.c
2267 and command_reply.c.
2269 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2270 the _from_client and _from_server functions. Affected file
2273 * Added silc_client_get_channel_by_id_resolve to the file
2274 lib/silcclient/silcapi.h to resolve channel information by
2275 its ID. Added also silc_client_get_channel_by_id that
2276 does not resolve it from the server.
2278 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Added SilcServerEntry context into the client library
2281 to represent one server. The INFO command now allocates
2282 these to save the resolved server info. For now on the
2283 client library will also keep information about servers,
2284 connected and resolved with INFO.
2286 The INFO command now allocates the SilcServerEntry context
2287 and saves the server info there. The COMMAND_REPLY in
2288 the INFO now returns the parameters to application in
2289 same order as defined in the protocol specification.
2291 The entries are cached in the client->server_cache.
2293 * The INFO command is now issued after received the Client ID
2294 from the server. Affected file lib/silcclient/client.c.
2296 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2297 to the application as the mode changer might be server.
2298 It is guaranteed that NULL is not returned anymore to the
2299 application. Affected file lib/silcclient/client_notify.c.
2301 The ID Type is now also passed to the application so that
2302 it can check whether the returned entry is SilcClientEntry
2305 Added new function silc_client_get_server_by_id to return
2306 the server entry by ID. Affected files are the
2307 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2309 * Do not create the channel in the Irssi SILC Client when issuing
2310 the JOIN command but when received the sucessful JOIN command
2311 reply. Otherwise the channel might get created even though we
2312 could not join it. The Affected file is
2313 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2315 * Fixed a channel joining bug in router. The router must also
2316 check the channel modes, invite and ban lists etc. when serving
2317 the JOIN command sent by normal server. Affected file is
2318 silcd/command.c. The router now resolves the client's
2319 information from the server who sent the JOIN command if it
2320 does not know it, and processes the JOIN command only after
2323 * Changed the SilcCommandCb to take new argument; void *context2.
2324 Affected file lib/silccore/silccommand.h
2326 The second argument in the command callbacks in the server now
2327 includes the SilcServerCommandReplyContext if the command was
2328 called as pending command callback from the command reply.
2329 Otherwise it is NULL. When called as pending the status of the
2330 command reply will be checked and if it was erronous the
2331 error will be sent to the original sender of the command.
2332 This way the client always receives the error messages even
2333 though the server was actually the one who received the error
2334 when it resent the command to router, for example. Affected
2335 files silcd/command[_reply].[ch].
2337 * Fixed sending WHOWAS command's error message to client if
2338 the requested client could not be found. It was missing.
2341 * Changed the CMODE and CUMODE commands reply arguments in the
2342 protocol specification. The Channel ID is now sent in both
2343 of the commands to identify the channel. Implemented this
2344 new feature to the client and server. Affected files
2345 lib/silcclient/command_reply.c and silcd/command.c.
2347 * Made better checks for invite and ban lists in the JOIN
2348 command in server. Affected file silcd/command.c.
2350 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2352 * The server now performs the incoming host IP/DNS lookup
2353 using the silc_socket_host_lookup and thus does not block
2354 the server anymore. Affected file silcd/server.c.
2356 * Completed the multi-thread support for SILC Scheduler in
2357 the lib/silcutil/silcschedule.c.
2359 * Fixed the configure.in.pre to detect the pthread correctly
2362 * Fixed a deadlock in silc_task_queue_wakeup in the file
2363 lib/silcutil/silctask.c.
2365 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Added new function silc_schedule_wakeup that is used in
2368 multi-threaded environment to wakeup the main thread's
2369 schduler. It needs to be used when a thread adds a new task
2370 or removes a task from task queues. After waking up, the
2371 scheduler will detect the task queue changes. If threads
2372 support is not compiled in this function has no effect.
2373 Implemented the wakeup mechanism to both Unix and WIN32
2374 systems. Affected files are lib/silcutil/silcschedule.[ch],
2375 lib/silcutil/unix/silcunixschedule.c and the
2376 lib/silcutil/win32/silcwin32schedule.c.
2378 * Added new function silc_task_queue_wakeup to wakeup the
2379 scheduler by the specified task queue. Affected file
2380 lib/silcutil/silctask.[ch].
2382 * The silc_socket_host_lookup_start now wakes up the scheduler
2383 after adding the timeout task. Affected file is
2384 lib/silcutil/silcsockconn.c.
2386 * The silc_socket_host_lookup is synchronous now if the threads
2387 support is not compiled in. However, the callback is still
2388 called asyncronously through the scheduler, anyway. Affected
2389 file lib/silcutil/silcsockconn.c.
2391 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Added new function silc_socket_host_lookup to perform
2394 asynchronous IP and FQDN lookups for the socket connection.
2395 Affected files lib/silcutil/silcsockconn.[ch].
2397 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2400 that may or may not compile the mutex support in.
2402 Changed the silc_mutex_alloc interface. It allocates the
2403 mutex now to the sent pointer and returns TRUE or FALSE.
2405 Affected file lib/silcutil/silcmutex.h.
2407 * Wrote the SILC Task Queue interface to support multi-threads.
2408 Affected file lib/silcutil/silctask.[ch].
2410 * Wrote the SILC Scheduler to support multi-threads. Affected
2411 file lib/silcutil/silcschedule.c.
2413 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2415 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2416 in lib/silcutil/win32/.
2418 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Defined SILC Mutex API and SILC Thread API and implemented
2421 them for Unix. Affected files are
2422 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2423 lib/silcutil/unix/silcunixmutex.c and
2424 lib/silcutil/unix/silcunixthread.c.
2426 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Fixed the silc_server_remove_clients_by_server's channel
2429 key re-generation. The hash table handling was incorrect
2430 and would not work with many channels. Affected file is
2433 * Fixed some memory leaks around the server code.
2435 * Rewrote the silc_server_get_users_on_channel to support IPv6
2436 based Client ID's. Affected file silcd/server.c.
2438 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2439 specification. However, a separate document must be written
2440 to define the detailed signing procedure and the payload
2441 associated with the flag. Defined the flag to the
2442 lib/silccore/silcchannel.h as well.
2444 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Changed the dynamic tables to static size tables in the
2447 lib/silccrypt/silchmac.c.
2449 * Removed GCC dependencies from the code. A patch by cras.
2451 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Do not show the error "Error receiving packet bla bla"
2454 in server if it really was not an error (-2 means that reading
2455 is pending). Affected file silcd/server.c.
2457 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2459 * Fixed a possible crash in silc_server_remove_clients_by_server
2460 in silcd/server.c. Fixed there also some memory leaks.
2462 * Fixed the silc_idlist_replace_client_id. It could replace
2463 wrong key in the hash table. Affected file silcd/idlist.c.
2465 * Do not check whether there are global users on the channel
2466 if the channel->global_users is FALSE. Affected functions
2467 silc_server_remove_from_one_channel and
2468 silc_server_remove_from_channels in silcd/server.c. Also,
2469 do not check if the removed client is local as we can be
2470 sure that global client was not removed from the channel
2471 and checking for global users is not needed.
2473 * The silc_server_remove_clients_by_server now re-generates
2474 the channel keys correctly for those channels that had
2475 clients removed from them. Affected file silcd/server.c.
2477 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2479 * Found the reason of random crashes in the server. We weren't
2480 ignoring the SIGPIPE signal (which can be sent in write())
2481 and it crashed the server. Affected file silcd/silcd.c.
2483 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * Assure that sock->user_data is not NULL in the function
2486 silc_server_packet_send in silcd/packet_send.c.
2488 * Disconnect the remote connection if it could not be added
2489 to any ID lists in the server. The affected file is
2492 * Check in silc_server_packet_send[_real/dest] that the
2493 socket is not disconnecting and ignore the data if it is.
2494 Affected file silcd/packet_send.c.
2496 * Define inline to __inline on native WIN32 compilation.
2497 Affected file includes/silcwin32.h.
2499 * Added some explicit type casts for inline code since MSVC
2500 require them. Affected files lib/silcutil/silcbuffer.h,
2501 lib/trq/silcdlist.h and lib/trq/silclist.h.
2503 * Print warning in log files from now on if the packet
2504 decryption fails. Affected file silcd/server.c.
2506 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Changed the `say' client operation's interface to accept
2509 new `type' argument to indicate the type of the message sent
2510 by the library. The application may filter the library's
2511 messages according the type. The affected file is the
2512 lib/silcclient/silcapi.h.
2514 * Added two new functions to lib/silcclient/silcapi.h:
2515 silc_client_del_client and silc_client_del_client_by_id.
2516 Affected file lib/silcclient/idlist.c.
2518 * Moved the clientincludes.h from includes/ to silc/ and
2519 serverincludes.h from includes/ to silcd/.
2521 * The modes for the CMODE and CUMODE are now passed as
2522 uint32 for application with COMMAND_REPLY. The affected
2523 file is lib/silcclient/command_reply.c.
2525 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * /WHOIS without arguments shows client's own information.
2528 Affected file lib/silcclient/command.c.
2530 * Changed PING to not accept any arguments. The specs
2531 says that client can ping only the connected server so
2532 requiring an argument is not needed. Affected file is
2533 lib/silcclient/command.c.
2535 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Fixed a fatal bug in private message sending and reception
2538 encryption and decryption when using private message keys.
2539 The implementation was incorrect and did not follow the
2540 specification. It causd that some of the message were
2541 lost since it did not use the sending and receiving keys
2542 as the protocol suggests. This has been fixed and will cause
2543 incompatibilities with older clients when sending private
2544 message encrypted with private message keys. Affected files
2545 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2546 and various other in Irssi SILC Client.
2548 Added `responder' boolean argument to the functions
2549 silc_client_add_private_message_key[_ske] to indicate when
2550 the key is added as responder or initiator of the key
2553 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2555 * Removed the silc_ske_check_version function and created
2556 a SilcSKECheckVersion callback. Added also a function
2557 silc_ske_set_callbacks that is now used to set all SKE
2558 callbacks. The callback functions are not given to
2559 the SKE functions anymore, but this function is used to
2562 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2564 * Added `silc_version' argument to the silc_client_alloc
2565 to define the version of the application for the library.
2566 The library will use the version string to compare it
2567 against the remote host's (usually a server) version
2568 string. Affected file lib/silcclient/silcapi.h
2570 * Added the KE protocol context to Key Agreement context
2571 in client library so that we can abort the SKE if it
2572 is in process when we get timeout. Affected file is
2573 lib/silcclient/client_keyagr.c.
2575 * Do not resolve the client ID forever if it returns in the
2576 first time that such client does not exist. This was done
2577 for example with private message. Affected file is
2578 lib/silcclient/client_prvmsg.c.
2580 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Do not add regex.h for WIN32. The affected file
2583 includes/silcincludes.h.
2585 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2586 not work yet 100%. It generates the DLL's automatically
2587 when compiling with --with-win32 under cygwin.
2589 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * lib/contrib/regex.c is not compiled on WIN32.
2593 * Added silc_net_get_socket_opt function to the
2594 lib/silcutil/silcnet.h.
2596 * Added includes/silcwin32.h for WIN32 specific includes
2599 * Do not use ptime structure or any of the posix process
2600 functions on WIN32 in lib/silccrypt/silrng.c.
2602 * Added silc_gettimeofday to provide generic function
2603 for struct timeval on all platforms. Added the function
2604 to lib/silcutil/silcutil.h.
2606 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2609 library as they clearly belong there. As a plus side we
2610 can make the actual socket connection routines platform
2613 Added also new generic function silc_socket_read and
2614 silc_socket_write (that used to be silc_packet_[read/write].
2615 The implementation of these are platform specific.
2617 * Added WIN32 specific routines of silc_socket_[read/write]
2618 to lib/silcutil/win32/silcwin32sockconn.c.
2620 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Added preliminary support for native WIN32 compilation under
2623 cygwin (using the -mno-cygwin option for GCC) to the
2624 ./configure.in.pre. The --with-win32 now prepares the
2625 compilation for native WIN32.
2627 * Rewrote the SILC Scheduler interface in the file
2628 lib/silcutil/silcschedule.h. The scheduler is now context
2629 based and does not have anymore any global static scheduler.
2630 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2631 and created lib/silcutil/win32 directory for WIN32 based
2634 * Added Unix specific network routines to the
2635 lib/silcutil/unix/silcunixnet.c and the old
2636 lib/silcutil/silcnet.c includes now only generic routines.
2638 Added WIN32 specific network routines to the
2639 lib/silcutil/win32/silcwin32net.c.
2641 * Added Unix specific utility functions from the
2642 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2644 * Added WIN32 SILC Scheduler to the file
2645 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2648 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Do not handle JOIN notify in the server if the target client
2651 is not registered (idata->registered == FALSE). The affected
2652 file is silcd/packet_receive.c.
2654 * Update the nickrec->founder in event_cumode in the Irssi SILC
2655 client. Affected file irssi/src/silc/core/silc-channels.c.
2657 * Fixed the CUMODE_CHANGE notify handling in the server when
2658 server and router are announcing their clients on channels.
2659 Now the mode changes are saved and notified correctly. The
2660 affected file is /silcd/packet_receive.c.
2662 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2663 They really did not replace the cache entry in the ID Cache.
2664 Now they do that. Affected file silcd/idlist.c.
2666 * Fixed the KICK notify handling in the Irssi SILC client to
2667 update the channel records so that the kicked client does not
2668 appear to be on the channel. The affected file is
2669 irssi/src/silc/core/silc-channels.c.
2671 * Always update the conn->current_channel when executing command
2672 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2674 * Fixed the KILL notify handling in Irssi SILC client to remove
2675 the killed client on all channels.
2677 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Fixed the silc_parse_command_line to remove extra spaces
2680 from the start and end of the arguments. Affected file is
2681 lib/silcutil/silcutil.c.
2683 * Cancel and free any active protocol in the function
2684 silc_server_close_connection. Affected file silcd/server.c.
2686 * Cancel and free any active protocol in the function
2687 silc_client_close_connction. Affected file is
2688 lib/silcclient/client.c.
2690 * Do not execute the KILL command for clients that are in
2691 history (ie. they are not in the network). Affected file is
2694 * Fixed KILL notify handling, client does not crash anymore.
2695 Affected file irssi/src/silc/core/silc-channels.c.
2697 * Reduced the default packet buffer size from 2048 to 1024 in
2698 lib/silccore/silcpacket.c.
2700 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2701 counter to the SKE context that is incresed when the SKE library
2702 performs async operation outside the library. If the outside
2703 process frees the SKE context and FREED status will be set
2704 and the library will detect after the sync operation that the
2705 libary is freed. The affected files are
2706 lib/silcske/silcske[_status].[ch].
2708 * Resolve the client entry information in the function
2709 silc_client_channel_message to assure that NULL pointer is not
2710 passed as client entry to the application. */
2712 * Fixed the task timeout calculation to assure that there is
2713 never negative timeouts. The affected file is
2714 lib/silcutil/silcschedule.c.
2716 * Fixed the channel user mode notification sending in server.
2717 It was sent point-to-point to the router (or to server by router)
2718 but it needs to be destined to a channel. The routines now
2719 supports sending the channel user mode notifys to the channels
2720 when announcing clients and channels. Affected files are
2721 silcd/server.c and silcd/packet_receive.c.
2723 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2724 It did not actually replace the old channel entry in the cache.
2725 Affected file lib/silcclient/client_notify.c.
2727 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Fixed a possible crash in silc_packet_send_prepare. It now
2730 assures always that there is enough space in the buffer and
2731 at the tail area of the buffer (for MAC).
2733 Fixed the inbound buffer reallocation in silc_packet_read.
2734 It was old code and did not handle the reallocation correctly.
2737 The affected file is lib/silccore/silcpacket.c.
2739 * Fixed buffer overflow in silc_parse_nickname in the file
2740 lib/silcutil/silcutil.c.
2742 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * make install generates new server keys only if there is not
2747 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2749 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2750 Added check that if the NOREPLY is set then we will not send
2751 the away message. This avoids infinite loop of away messages
2752 if both clients are away. The affected file is
2753 lib/silcclient/client_prvmsg.c.
2755 * Fixed client crash if /NICK was given without arguments.
2756 Affected file lib/silcclient/command.c.
2758 * Server does not send the invite list in INVITE command back
2759 to the client if the list was not altered. Added this notion
2760 to the protocol spec as well. Affected file silcd/command.c.
2762 Fixed possible crash in INVITE command by checking the
2763 value of silc_server_get_client_route command.
2765 * Fixed the INVITE notify type handling. The arguments are now
2766 taken in correct order and client does not crash. The affected
2767 file is irssi/src/silc/core/silc-channels.c.
2769 Removed the "Inviting xxx to channel" message from the
2770 client library away and let the application handle it.
2771 Affected file lib/silcclient/command.c. Added that message
2772 to Irssi SILC client's message formats.
2774 * Fixed CMODE command crash in client. It now checks the
2775 amount of arguments correctly and does not crash. The affected
2776 file is lib/silcclient/command.c.
2778 * Do not create new channel automatically in silc_channels_join
2779 but check whether the channel by that name already exists.
2780 Affected file irssi/silc/core/silc-channels.c.
2782 * Do not send the SERVER_SIGNOFF to router if the disconnected
2783 entity was the router. Affected file silcd/server.c.
2785 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2786 SILC client as it was missing from there.
2788 Added the handling of the KICK notify to the Irssi SILC client
2789 as it was missing. Added "you have been kicked" message to
2790 Irssi SILC client's message modules formats.
2792 Added the handing of the KILL notify to the Irssi SILC client
2793 as it was missing. Added the kill message module formats
2796 The affected file is irssi/src/silc/core/silc-channels.c.
2798 * The router did not save the channel mode the server announced.
2799 Affected file silcd/packet_receive.c.
2801 * Fixed a possible crash in INFO command in server. If the
2802 server did not provide the server info it crashed. Affected
2803 file silcd/command.c.
2805 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Fixed the GETKEY command in the server to check also the
2808 global list. Otherwise the GETKEY would not work correctly
2809 in normal SILC server. Affected file silcd/command.c.
2811 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Fixed GETKEY crash, it crashed if the command did not succseed.
2815 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2818 is now real and not just an macro interface to GMP.
2820 Removed the entire GMP from the source tree and imported new
2821 NSS MPI library instead. Reason for removing GMP is that it is
2822 extremely large and compiles extremely slow. The NSS MPI
2823 is only a few files and compiles in less than 10 seconds.
2824 The speed is also about the same as GMP. The MPI is imported
2825 to lib/silcmath/mpi.
2827 If the system has GMP installed we will still use the GMP.
2828 If it is not then the NSS MPI will be compiled.
2830 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Merged a long nickname (127 characters long) crash bugfix from
2833 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2835 * Merged a freed memory reference bugfix from Irssi CVS tree.
2836 Affected file irssi/src/core/commands.c.
2838 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added the server's public key sving and verification to the
2841 server when performing the SKE. This was missing and the
2842 remote server's (or router's) public key was accepted without
2843 checking whether we have it previously or trust it at all.
2844 Affected file silcd/protocol.c.
2846 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Check in the silc_server_timeout_remote if protocol is active
2849 and make sure that the protocol's final callback is called so
2850 that all memory if freed. Affected file silcd/server.c.
2852 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * silc_server_whois_send_reply crashed the server if the nickname
2855 was 127 characters long. Affected file silcd/command.c.
2857 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2859 * Added sanity check to the silc_server_new_client. If the hostname
2860 is provided inside username then check that the provided hostname
2861 really is the same as the resolved one. If the hostname was not
2862 resolved then check it from the public key. Affected file is
2863 silcd/packet_receive.c.
2865 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2866 if the server disconnected us and the connection is not valid
2867 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2869 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2870 the library to the lib/silcutil/silcutil.[ch].
2872 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Close log file after open. Affected file
2875 lib/silcutil/silclog.c.
2877 * Check whether sock == NULL in silc_client_send_packet and return
2878 if it is. Affected file lib/silcclient/silcclient.c.
2880 * Check rec->entry == NULL in the Irssi SILC Client before
2881 sending the channel message. Affecte file is
2882 irssi/src/silc/core/silc-servers.c.
2884 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Merged a splitted window bugfix from Irssi CVS tree. The
2887 affected file is irssi/src/fe-text/textbuffer-view.c.
2889 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2890 It did not print nickname.
2892 * Improved the distributions system a bit.
2894 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2897 irssi/src/fe-text/gui-window.c.
2899 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2900 to in-active server. The affected file is
2901 irssi/src/silc/core/client_ops.c.
2903 * Resolve the client in USERS command reply if the entry does
2904 not have username resolved. The affected file is
2905 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2906 command to WHOIS command to really resolve stuff. The USERS
2907 is not used any more in any critical section so WHOIS can
2908 be used even though it might be slower than IDENTIFY.
2910 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2913 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Changed the protocol API a bit more consistent in the
2916 lib/silccore/silcprotocol.[ch].
2918 * Changed the following headers to ROBODoc format:
2920 lib/silccore/silcpayload.h
2921 lib/silccore/silcprotocol.h
2922 lib/silccore/silcsockconn.h
2924 All core library headers are now formatted.
2926 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Fixed a bug in Irssi SILC client; do not show that you are
2929 server/router operator if you really are not. Affected file is
2930 irssi/src/silc/core/client_ops.c.
2932 * Renamed silc_command_free_payload to silc_command_payload_free.
2933 Affected file lib/silccore/silccommand.h
2935 * Added silcmath.h to include the prototoypes of various routines
2936 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2939 * Changed the following headers to ROBODoc format:
2941 lib/silccore/silcchannel.h
2942 lib/silccore/silccommand.h
2943 lib/silccore/silcid.h
2944 lib/silccore/silcidcache.h
2945 lib/silccore/silcmode.h
2946 lib/silccore/silcnotify.h
2947 lib/silccore/silcpacket.h
2948 lib/silcmath/silcmath.h
2950 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2952 * Added checking to the server code not to start the server if
2953 ciphers and stuff are not configured properly. Affected files
2954 silcd/serverconfig.[h] and silcd/server.c.
2956 * Changed the layout of the header files of the public interfaces
2957 in the SILC libraries. The new layout supports ROBODoc
2958 documentation tool (and some others) so that it is easy to create
2959 a library reference manual. All the other headers and source
2960 code must still follow the CodingStyle document. Also source
2961 code must not include these ROBODoc stuffs, only the headers.
2962 Furthermore, all public interface headers must now be named
2963 by using `silc' prefix, example: silcapi.h, silccipher.h.
2964 Some files were renamed due to this. All the other headers
2965 must not be used as public interfaces. I will update the
2966 CodingStyle document later. Changed following headers, so far:
2968 lib/silcclient/silcapi.h
2969 lib/silccore/silcauth.h
2970 lib/silccore/silcprivate.h
2971 lib/silccrypt/silcdh.h
2973 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Removed silc_client_packet_send_flush from the client library
2978 as it is not needed. Affected file lib/silcclient/client.[ch].
2980 * Added printing of message of unresolved authentication method
2981 to the Irssi SILC client. Added it to the module formats.
2982 Removed the same message from the client library.
2984 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Added new distribution feature, DISTLABEL. Every distribution
2987 can define own preprocessor label that can be used in the
2988 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2989 file distributions, acconfig.h.pre and prepare.
2991 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Added Makefile.defines_int to include the actual definitions
2994 for Makefile.defines.in. Tested the new distribution system,
2995 created distributions and tested installation.
2997 * Added AWAY message printing to the Irssi SILC client. Added
2998 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3000 * Added SCONNECT command to call the SILC's CONNECT command.
3001 Cannot use CONNECT directly since Irssi uses that internally.
3002 Affected file irssi/src/silc/core/silc-servers.c.
3004 Added ACTION local command. It is same as ME command but takes
3005 the channel as mandatory argument.
3007 Rewrote some of the Irssi's help files to suite for SILC
3010 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3012 * Added Makefile.defines[.in] that should for now on be included
3013 in all Makefile.am file in the source tree. That file includes
3014 all common compilation definitions for SILC source tree.
3016 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Minor changes to the ./prepare script to change the package
3019 name according the distribution name to the configure.in.
3021 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3023 * Created new distribution system. Added file `distributions'
3024 that defines all the distributions that can be created out of
3025 the SILC source tree. The ./prepare script now reads that
3026 file to determine how to prepare the distributions. The
3027 first argument to the ./prepare is the name of the distribution
3028 and second is the version of the distribution. If given
3029 without arguments it creates the default (toolkit) distribution
3030 with the default version (defined in ./prepare).
3032 All Makefile.am files that are subject to the distributions
3033 are now named as Makefile.am.pre. These are ./Makefile.am
3034 and lib/Makefile.am. Others may be changed later.
3036 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3038 * Added invite list, ban list, some key management and connection
3039 error message printing to module formats in the Irssi SILC client.
3041 * Added new silc_client_set_away_message to set the away message
3042 that is back to the person who sent private message. The
3043 affected file lib/silcclient/silcapi.h and the
3044 lib/silcclient/client_prvmsg.c.
3046 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3048 * Fixed the private message sending in the Irssi SILC client,
3049 added local command KEY to the Irssi SILC client.
3051 Added key management and key agreement message formats to the
3052 irssi/src/fe-common/silc/module-formats.[ch].
3054 Added USERS (alias WHO) printing, server/router operator
3055 indication and LIST command printing to the module formats.
3057 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Fixed channel joining notify handling, cumode notify handling
3060 from Irssi SILC client.
3062 * Added SILC specific module-formats to the Irssi SILC client so
3063 that SILC specific message hilighting, colors etc is possible.
3064 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3066 Added channel mode, channel user mode, actions, notices,
3067 whois and whowas printing to the the module-formats.c.
3069 * Fixed a bug in channel deletion in the server. The channel
3070 is not left to the cache even if the channel founder auth mode
3071 is set when there are no users anymore on the channel. Affected
3072 file silcd/server.c.
3074 * The silc_net_localhost now resolves the entire hostname including
3075 the domain name. Affected file lib/silcutil/silcnet.c.
3077 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Changed the ask_passphrase client operation to be ascynchronous.
3080 It has now a completion callback and a context that the
3081 application must call after it has got the passphrase from
3082 the user. Affected files lib/silcclient/silcapi.h,
3083 lib/silcclient/protocol.c, lib/silcclient/command.c and
3086 Added SilcAskPassphrase callback that the application calls
3087 to deliver the passphrase to the library.
3089 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3090 The public key verification and especially a certificate
3091 verification is asynchronous procedure.
3093 Added new SILC_SKE_STATUS_PENDING status to indicate the
3094 request is pending and a callback will be called to finalize
3097 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3098 indicate that remote end did not send its public key (or
3099 certificate), even though we require it. Added check for this
3100 condition in the SKE. This was a security bug, now fixed.
3102 Defined new SilcSKEVerifyCbCompletion callback that is called
3103 when the verification process is completed.
3105 The affected files lib/silcske/silcske_status.h and
3106 lib/silcske/silcske.[ch].
3108 * Changed the verify_public_key client operation to be async
3109 as well. Defined SilcVerifyPublicKey callback that is used to
3110 indicate the success of the public key verification process.
3112 Changed the server and client to use the new async client
3115 * Changed the Irssi SILC client's internal scheduler to be called
3116 twice as many times as it used to be. As a result the client
3117 should be a bit faster now. Affected file is
3118 irssi/src/silc/core/silc-core.c.
3120 * Added support to Irssi SILC client of asynchronous public key
3121 verification and passphrase inquiry. Affected file is
3122 irssi/src/silc/core/silc-core.c.
3124 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Do not say "You have left channel %s" in client library.
3127 Moved it to the application. Affected files are
3128 lib/silcclient/command.c and silc/client_ops.c.
3130 * Fixed silc_client_get_clients. Command context was not
3131 duplicated and was freed memory in the callback. Affected
3132 file lib/silcclient/idlist.c.
3134 * Do not say "you are now talking..." on JOIN command in the
3135 client library. The appliation must handle it.
3137 * Do not say ".. changed topic to" in command reply in the
3138 client libary. The application must handle it.
3140 * Fixed TOPIC command sending in the client library.
3142 * Fixed a memory leak in silc_client_command_free in the file
3143 lib/silcclient/command.c.
3145 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Imported a modified version of Irssi client to the source tree.
3148 The Irssi will be used to create a new client called
3149 Irssi SILC. Imported to irssi/.
3151 Added silc_core_init_finish function to the Irssi. Affected
3152 file irssi/configure.in.
3154 A lot changes in the Makefile.ams around the irssi tree.
3156 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3158 * Do not rehash if the new size is same as the old size of the
3159 hash table, in the silc_hash_table_rehash*. The affected file
3160 lib/silcutil/silchashtable.c.
3162 * Replaced hash_table_del_by_context calls from the server
3163 (when channel->user_list and client->channels) to the
3164 hash_table_del as it is sufficient and faster.
3166 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Added silc_hash_table_list, silc_hash_table_get and the
3169 SilcHashTableList structure to provide an alternative way to
3170 traverse the hash table. The affected files are
3171 lib/silcutil/silchashtable.[ch].
3173 * Changed the server's idlist routines to use the hash table
3174 routines to optimize the code.
3176 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3178 * Replaced the client entry's `channel' list and channel entry's
3179 `user_list' list to hash tables for optimized lookup. Changed
3180 the code to use the hash table interface around the code.
3181 Affected file lib/silcd/idlist.[ch].
3183 * Added `auto_rehash' boolean argument to the function
3184 silc_hash_table_alloc to indicate whether the hash table should
3185 auto-rehash when it thinks is appropriate time. It will
3186 increase the hash table size if the there is twice as much
3187 entries in the table than the size of the table, and will
3188 decrease the size if there are twice as less entries than
3189 the size of the table.
3191 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3193 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3195 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * silc_idcache_purge_by_context deletes the entry now by context
3198 as it is supposed to do. Affected file lib/silccore/idcache.c.
3200 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3201 client is not anymore valid (WHOWAS givens the info) and not
3202 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3204 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Removed the `data' and `data_len' arguments from the ID Cache
3207 interfaces and added `name' argument. ID Cache does not handle
3208 anymore the binary data only a names associated with given ID.
3210 * When hashing a Client ID with silc_hash_id the entire ID is
3211 not hashed anymore, instead only the hash of the Client ID is
3212 hashed. This way we can access the Client ID from the cache
3213 with Client ID but with the hash of the ID (which is a hash of
3214 the nickname) as well without any difference in performance.
3216 Added also silc_idcache_find_by_id_one_ext to do one on one
3217 searching when we have the actual ID. Added also function
3218 silc_hash_client_id_compare. The affected files are
3219 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3221 * When hashing the name associated with a ID it is always done
3222 in lowercase. This way we can access the cache without worrying
3223 about case-sensitivity, even though, for example nicknames are
3226 * Fixed a bug in server with channel message sending. It put
3227 wrong ID type as destination ID. The affected file
3228 silcd/packet_send.c.
3230 * silc_idcache_del_by_context now deletes from all hash tables
3231 by context. Affected file lib/silccore/idcache.c.
3233 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Changed the client library to use the new ID Cache interface.
3236 Changes around the source tree.
3238 * Added silc_hash_table_rehash_ext to rehash with specific
3239 hash function. Affected file lib/silcutil/silchashtable.[ch].
3241 * Added silc_hash_string_compare to compare two strings in the
3242 hash table. Affected file lib/silcutil/silcutil.[ch].
3244 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Added new function silc_idcache_del_by_context into the
3247 lib/silccore/idcache.[ch].
3249 * Changed the server's ID list routines to use the new ID Cache
3250 interface. Changes around the source tree.
3252 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Added silc_hash_table_del[_by_context]_ext functions in to the
3255 lib/silcutil/silchashtable.[ch].
3257 Removed silc_hash_table_find_all* routines and added new
3258 silc_hash_table_find_foreach to replace them.
3260 Added silc_hash_table_replace_ext function as extended
3261 replacing function. Separated the simple hash table interface
3262 from the extended hash table interface in the file
3263 lib/silcutil/silchashtable.h.
3265 * Fixed minor bugs and changed it to use some of the new
3266 hash table functions in lib/silccore/idcache.c
3268 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Added new function silc_hash_table_find_all to return all keys
3271 in the hash table by the specified key. As the hash table is
3272 collision resistant it also makes it possible to have several
3273 duplicate keys in the hash table. This function may be used to
3274 find all of the keys from the hash.
3276 Added user_context arguments to the SilcHashFunction,
3277 SilcHashCompare and SilcHashDestructor to deliver user specified
3280 Added new fuctions silc_hash_table_find[_all]_ext to do
3281 extended lookup with specified hash and compare functions and
3282 specified user contexts.
3284 Added new function silc_hash_table_add_ext to add the key
3285 with specified hash function and user context.
3287 Added new function silc_hash_table_foreach to traverse all
3288 entrys in the hash table. Added SilcHashForeach callback
3291 Added new function silc_hash_table_del_by_context to delete
3292 the entry only if the context associated with the key matches.
3294 Affected files are lib/silcutil/silchashtable.[ch].
3296 * Removed silc_hash_[server/client/channel]_id and added just
3297 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3298 silc_hash_id_compare to compare two ID's using as the hash table
3299 comparison function. Added also silc_hash_data to hash
3300 binary data and silc_hash_data_compare to compare it.
3302 * Removed silc_idlist_find_client_by_hash as it is not needed
3303 anymore. Affected file silcd/idlist.[ch].
3305 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3306 to use internally the SilcHashTable. The new ID Cache is a lot
3307 faster than the old one. Some of the ID Cache interface was also
3308 rewritten and obsolete and stupid functions were removed.
3310 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Added entry_count field to the SilcHashTable to keep the number
3313 of the entries in the table. Implemented the function
3314 silc_hash_table_rehash. Added new function
3315 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3317 Fixed a minor bug in silc_hash_table_free.
3319 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3320 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3321 into the lib/silcutil/silcutil.[ch].
3323 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Implemented a collision resistant hash table into the
3326 lib/silcutil/silchashtable[ch]. See the header and the source
3327 for the SilcHashTable API.
3329 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Merged dotconf version 1.0.2 into lib/dotconf.
3333 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Do not compile anything in lib/silcsim/* if the SIM support
3336 is not enabled. The tree should now compile without problems
3339 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Compiled the SILC under cygwin. Compiled and tested briefly
3342 without problems. More tests needed. The SIMs didn't compile
3345 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3347 * Fixed possible crash in silc_get_username in the
3348 lib/silcutil/silcutil.c.
3350 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Fixed a va_arg in silc/client_ops.c.
3354 * Oops, RC5 routines were named AES and caused some problems
3355 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3357 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Added new SilcIDIP structure into the lib/silccore/id.h and
3360 replaced the old `ip' fields from all SILC ID's to that type.
3361 This is a step towards IPv6 support.
3363 The silc_id_get_len takes now the ID as an extra argument.
3364 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3365 both IPv4 and IPv6 based ID's.
3367 The affected files are lib/silccore/id.[ch] and other files
3368 around the tree using these routines.
3370 * Removed the ID length arguments in server from various
3371 silc_server_send_notify_* routines -> they are not needed
3374 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Fixed memory leak in silc_encode_pem_file in the file
3377 lib/silcutil/silcutil.c.
3379 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3381 * Check minor version as well in the SKE. Affected files are
3382 silcd/protocol.c and lib/silcclient/protocol.c.
3384 * Added --identifier option to the server so that an identifier
3385 can be when creating the public key for the server. Affected
3386 file is silcd/silcd.c.
3388 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3389 lib/silccrypt/silcpkcs.c.
3391 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3393 * Register default ciphers and stuff when using -C option with
3394 the server. Affected file sildc/silcd.c.
3396 * Put back the servers public key filename format, it is better
3397 than the new one. For now, the client keys are saved with the
3398 new filename format. The affected file silc/client_ops.c.
3400 * Implemented the Cipher API for the rest of the ciphers that
3401 did not implement it or implemented it the wrong way.
3403 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3405 * Register default ciphers and stuff when using the -S option
3406 in the client. Affected file silc/silc.c. Same also when
3407 creating new key pair with -C option.
3409 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Fixed the silc_verify_public_key client operation function to
3412 save the public keys differently. The fingerprint is now
3413 used as filename and not the hostname. This way also the
3414 client keys are saved uniquely and not with hostnames. The
3415 affected file is silc/client_ops.c.
3417 * Trimmed the silc_hash_fingerprint function to remove extra
3418 whitespaces from the end of the fingerprint. The affected
3419 file is lib/silccrypt/silchash.c.
3423 * Added silc_cipher_register_default function to register all
3424 default ciphers. It can be used when configuration files
3425 does not exist and the application does not want any specific
3426 ciphers in any specific order.
3428 The SilcDList is now used as silc_cipher_list dynamically
3429 allocated cipher list. Removed the static list all together
3430 and now all ciphers must be allocated to the dynamic list.
3431 The silc_cipher_alloc routine was changed to check only the
3434 All silc_cipher_* routines that used to return int returns
3437 The affected files lib/silccrypt/silccrypt.[ch].
3439 * The same thing was done to silc_hash_* as for silc_cipher_*
3440 routines. Affected files lib/silccrypt/silchash.[ch].
3442 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3443 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3444 Added also silc_pkcs_[un]register[_default] functions.
3445 Removed the data_context from the PKCS API.
3447 * Added silc_hmac_register_default function to register default
3448 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3449 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3450 to unregister all hmacs at once.
3452 * Register the default ciphers, hash functions, PKCSs and HMACs
3453 if client's configuration file does not exist. The affected
3456 * The client did not load the hash functions from the SIM
3457 modules at all. Added support for this. Affected file is
3458 silc/clientconfig.c.
3460 * When decoding public key with silc_pkcs_public_key_decode, check
3461 the supported algorithm only if PKCS are registered. Affected
3462 file lib/silccrypt/silcpkcs.c. The same was done with the
3463 silc_pkcs_private_key_decode.
3465 * Fixed the SILC List routines to keep the list always in order.
3466 It used to change the list's order when traversing the list but
3467 not it preserves the order. Affected file lib/trq/silclist.h.
3469 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added the client library to use the SilcSocketConnection's
3472 reference counter (by silc_socket_dup) to prevent the bug that
3473 the socket object may be freed underneath async operation.
3475 * The name resolv library checking fixes in the configure.in.pre.
3478 * Created new version of the protocol drafts for future
3479 development. The -03 drafts are the ones that will be changed
3480 in the trunk now and the -02 will remain as they are.
3482 * Send list of CUMODE notifys to the router when announcing
3483 the channel users to the router. Affected file silcd/server.c.
3484 If the router receiving channel founder CUMODE for a channel
3485 that already has channel founder it will send CUMODE notify
3486 to the sender to remove the channel founder rights from the
3487 announced client. Affected file silcd/packet_receive.c.
3489 * The CUMODE notify may now use Server ID as well as the entity
3490 who changes the mode. Updated protocool specs.
3492 * Updated INSTALL and README files.
3494 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3496 * New web pages in the http://silc.pspt.fi. The pages was
3501 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Implemented the [DenyConnectin] config section in the server.
3504 Added silc_server_config_denied_conn to check whether incoming
3505 connection is denied. Affected file silcd/serverconfig.[ch].
3507 * Do not check the ports when checking the incoming configuration
3508 data if the port is 0, meaning any. Affected file is
3509 silcd/serverconfig.c.
3511 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Fixed buffer overflow in silc_string_compare in the file
3514 lib/silcutil/silcutil.c.
3516 * Fixed double free in silc_server_command_leave in the file
3519 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Fixed the version checking in the server. Affected file is
3524 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3526 * Fixed the configuration data fetching when accepting new
3527 connections in the server. Affected file silcd/server.c.
3529 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Added `sender_entry' argument to the function
3532 silc_server_packet_relay_to_channel so that we can check
3533 whether some destination actually belongs to the same route
3534 the sender belongs (ie, we must not resend the packet to the
3535 sender). Affected file silcd/packet_send.[ch].
3537 * Added `servername' field to the SilcClientEntry in the server
3538 to hold the name of the server where client is from. Affected
3539 file is silcd/idlist.h.
3541 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3543 * Moved the channel message encrypting in the router betwen
3544 router connections from silc_server_channel_message to the
3545 silc_server_packet_relay_to_channel since we want to check
3546 whether we have anybody channel before encrypting anything.
3547 Affected files silcd/packet_[receive/send].c.
3549 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Fixed the [AdminConnection] server config section to support
3552 multiple entries. Affected file silcd/serverconfig.c.
3554 * Added support into the server to check the validity of the
3555 incoming connection before executing any KE or authentication
3558 * The connection configuration is now saved to the KE and
3559 connection auth protocol contexts and not fetched anymore in
3560 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3562 * The local hosts listenning address and port is also resolved
3563 now when starting the server. We want to have the socket object
3564 to include the real address and port for the listener. Added
3565 new function silc_net_check_local_by_sock into the files
3566 lib/silcutil/silcnet.[ch].
3568 * Fixed a broadcast bug in server -> do not broadcast if we
3571 * Fixed a routing bug. Do not route broadcast packets ever.
3572 Broadcast packets must be processed always and not routed since
3573 they may be destined to some other host than yourself and thus
3574 would get routed without no good reason. Affected file is
3577 * Added function silc_server_config_is_primary_route to check
3578 whether primary router connection has been configured (a router
3579 configuration that we are initiating). If there is not, we
3580 will assume that there is only two routers in the SILC network
3581 and we will use the incoming router connection as our primary
3582 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3584 * Changed the order of the broadcasting. Broadcast _after_ the
3585 packet has been processed not before. Affected file is
3588 * Fixed a [ClientConnection] parsing bug. The port was never
3589 parsed correctly thus resulting to port 0. Affected file
3590 silcd/serverconfig.c.
3592 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3593 argument and did not set the broadcast packet flag. Affected
3594 file silcd/packet_send.c. Fixed same bug in the function
3595 silc_server_send_notify as well.
3597 * If we receive NEW_ID packet for our own ID in the server, ignore
3600 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Removed the nickname from the Private Message Payload.
3605 Updated the code and the protocol specs.
3607 * Updated protocol specs for submitting to the IETF.
3609 * Tweaked the Random Number Generator a bit. Affected file
3610 lib/silccrypt/silcrng.c. Exported a new function
3611 silc_rng_[global]_add_noise which can be used to add more
3614 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Do not parse packets with different timeout when protocol
3617 is active -> may cause problem with rekey. Affected file
3620 * When server receives signoff notify it must not create
3621 new channel key if the client is on any channels since the
3622 sender of the signoff notify will create it.
3624 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * Added printing of error messages during SKE protocol from the
3627 failure packet sent by server during SKE. Affected file
3630 * Removed the client's failure_callback handling with timeout
3631 and handle it immediately when received.
3633 * The SKE library returned wrong type in SUCCESS and FAILURE
3634 packets. They must be 32 bit MSB not 16 bit MSB.
3636 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Ok, rewrote the logic of the re-key and now it seems to work.
3639 I tested it on high traffic with frequent re-keys without
3640 problems. Added hmac_receive (and renamed hmac to hmac_send)
3641 in SilcClientConnection in lib/silcclient/client.h and
3642 in SilcIDListData in silcd/idlist.h. Also, removed the
3643 SilcPacketParserContext's cipher and hmac fields as they are
3644 not needed anymore and actually caused some problems when
3645 the ciphers and hmac's changed underneath the packet parser.
3647 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3649 * If re-key protocol is active then process the incoming packets
3650 synchronously since we must assure that icoming packets encrypted
3651 with the old key is processed before the new keys is set to
3652 use. This is true other packets than for REKEY packets.
3653 Affected file silcd/server.c. The same was done to client library
3654 as well, affected file lib/silcclient/client.c.
3656 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * Fixed bug in client and server to accept the force send if
3659 the packet is send from silc_[server/client]_packet_process
3660 function. Otherwise the packets are never delivered, oops.
3662 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Disable force sending of packets when REKEY protocol is active.
3665 We must assure that no packet is sent directly when rekey is
3666 performed. All packets must be sent through packet queue.
3667 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3668 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3669 function is silc_[server/client]_packet_send_real to check
3672 * Replaced the SIM paths from example config files to
3673 /usr/local/modules. Also, make install creates now
3674 /usr/local/silc/logs directory to hold all the SILC server
3677 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Made the configure.in.pre work on Solaris. Patch by salo.
3681 * Made all ciphers compatible with non-x86 machines. Defined
3682 CBC mode macros into lib/silccrypt/ciphers_def.h.
3684 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Fixed the make install.
3688 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3690 * When MAC computation fails the silc_packet_decrypt returned 0
3691 even though it was supposed to return -1. Fixed this. The
3692 affected file is lib/silccore/silcpacket.c.
3694 * Do not replace the config files in /etc/silc (in make install)
3695 if they already exist. Affected file ./Makefile.am.
3697 * Do not send re-key packets immediately but through packet queue.
3698 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3700 * Changed silc_net_check_host_by_sock to return FALSE if the
3701 IP/DNS could not be resolved. Though, it returns the IP address
3702 now even if it could not resolve it (but returns also FALSE).
3703 Affected file lib/silcutil/silcnet.[ch].
3705 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Added silc_pkcs_decode_identifier to decode the public key's
3708 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3709 Added also silc_pkcs_free_identifier. Added also new context
3710 SilcPublicKeyIdentifier.
3712 * Added -S option to the silc client. It is used to dump the
3713 contents of the specified public key file.
3715 * Changed the PKCS api to return the public key length when
3716 setting the public key.
3718 * Fixed a fatal bug in the public and private key file loading.
3719 Affected file lib/silccrypt/silcpkcs.c.
3721 * Execute the packet parsing for client with zero (0) timeout
3722 if the protocol is active. Affected file silcd/server.c.
3724 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Made the key generation options to the silcd program. Added
3727 -C option, equivalent to client's option.
3729 * Added new [ServerKeys] config section to the server. It
3730 configures the server's public and private key.
3732 * Defined generic Public Key Payload into the protocol
3733 specification to send specific type of public keys and
3736 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3737 public key or certificate.
3739 * Implemented the GETKEY command to the server and to the
3740 client library and on user interface.
3742 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Made preliminary `make install' work.
3746 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Added SilcServerRekey context into silcd/idlist.h.
3750 * Added the PFS support as defined in the specification to the
3751 SKE protocol. Affected files lib/silcske/*.c.
3753 * Added `ske_group' field to the SilcServerRekey context to hold
3754 the number of the SKE group that is used with PFS in re-key.
3755 Affected file silcd/idlist.h.
3757 * Added PFS re-key support to the server. Affected file is
3760 * Added silc_protocol_cancel to cancel execution of the next
3761 state of the protocol. Affected file is
3762 lib/silccore/silcprotocol.[ch].
3764 * Added the re-key support with and without PFS to the client
3765 library. Re-key is performed once in an hour, by default.
3767 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3768 Added silc_client_rekey_callback and silc_client_rekey_final.
3769 Affected files are lib/silcclient/protocol.[ch] and
3770 lib/silcclient/client.[ch].
3772 * Removed the `hmac_key' and `hmac_key_len' fields from the
3773 SilcClientConnection structure; not needed. Affected file is
3774 lib/silcclient/client.h.
3778 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Do not ask whether user wants to use the negotiated private key
3781 for private messages, just use it. Affected file is
3782 silc/local_command.c.
3784 * Added `send_enc_key' and `enc_key_len' fields to the
3785 SilcIDListData structure since they are needed in the re-key
3786 phase. Affected file is silcd/idlist.[ch].
3788 * Implemented the simple re-key protocol into the server.
3789 Affected files silcd/server.c and silcd/protocol.[ch]. The
3790 re-key will be performed once in an hour, by default.
3792 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3793 Added silc_server_rekey, silc_server_rekey_callback and
3794 silc_server_rekey_final.
3796 * Removed Tunneled flag from the protocol. Updated the code
3797 and the specifications.
3799 * Adde `pfs' field to the SilcIDListData to indicate whether
3800 the PFS is to be performed in the re-key. Affected file is
3803 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3806 int64 of at least the xintXX size. If void * is less that 4
3807 bytes uint32 * will be used. Defined bool as boolean.
3809 * Changed _ALL_ unsigned long and unsigned int to uint32,
3810 unsgined short to uint16 in the source tree.
3812 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3813 not handle clients that has entry->data.registered == FALSE.
3814 They are not in the network anymore. Affected file is
3817 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3819 * Implemented the sending of the SERVER_SIGNOFF notify in the
3820 server. Affected file is silcd/server.c.
3822 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3823 Added also silc_notify_payload_encode_args into the
3824 lib/silccore/silcnotify.[ch].
3826 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3827 Affected file silcd/packet_receive.c.
3829 * Implemented the SERVER_SIGNOFF notify handling in the client
3830 library. Affected file lib/silcclient/client_notify.c. Also,
3831 implemnted the printing of the SERVER_SIGNOFF info to the
3832 application. Affected file silc/client_ops.c.
3834 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3835 if the deleting was successful. Affected file silcd/idlist.[ch].
3837 * Added support for public key authentication in the connection
3838 authentication protocol in the client library. Affected file
3839 lib/silcclient/protocol.c.
3841 * Changed the server's silc_idlist_get_clients_by_* interface
3842 to support already allocated array so that new entries may be
3843 added to pre-allocated array. Affected file silcd/idlist.[ch].
3844 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3845 and command replies.
3847 * All command reply functions in the server now calls the
3848 pending command callback even if error occured. This way the
3849 error will be delivered to the client as well. Affected files
3850 silcd/command.c and silcd/command_reply.c.
3852 * Fixed INFO command to return local server's info if no server
3853 was provided. Affected file lib/silcclient/command.c.
3855 * Removed RESTART command for good. Updated the code and the
3858 * Rewrote parts of the task system. It is a bit simpler now.
3859 Removed unsued task priorities. The affected files are
3860 lib/silcutil/silctask.[ch].
3862 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Moved the USERS printing from the library to the application.
3865 Affected files lib/silcclient/command.c and silc/client_ops.c.
3867 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Added channel key re-key support. The re-key is perfomed
3872 only by the router and is done once in an hour. Added `rekey'
3873 field to the SilcChannelEntry in the server. Affected files
3874 silcd/server.c and silcd/idlist.h.
3876 * Added silc_task_unregister_by_context into the file
3877 lib/silcutil/silctask.[ch].
3879 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Added SILC_UMODE_GONE mode to indicate when the client is not
3882 present in the SILC network. Added also support to the local
3883 command AWAY that will set this mode. Added support of showing
3884 "xxx is gone" in WHOIS command. The USERS command shows the
3885 gone status as well.
3887 * Fixed setting server and router operator privileges in the
3888 server's UMODE command. Affected file silcd/command.c.
3890 * Merged the SKE KE1 and KE2 payloads into one payload. The
3891 new KE payload is equivalent to the old KE2 payload.
3893 Cleaned up the SKE Start Payload parsing. It now uses the
3894 simple buffer unformatting to do the parsing. A lot faster
3897 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3898 to the SKE that is used to indicate whether both of the SKE
3899 parties should perform authentication. By default only the
3900 responder performs authentication. By setting this flag also
3901 the initiator must do authentication. By default it is unset
3902 since in normal SKE case, client to server connection, only
3903 the responder should do authentication. When doing SKE between
3904 two clients both should perform authentication. Updated the
3905 code and the protocol specs.
3907 * A little fix to IDENTIFY command in the server. Search the
3908 client first by hash not nickname. Affected file is
3911 * Fixed the silc_client_close_connection to support closing
3912 the client to client connections wihtout deleting too much
3913 data. Affected file lib/silcclient/client.c.
3915 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3916 are received if protocol used to be active but is not anymore
3917 the application would crash due to NULL pointer dereference.
3918 Affected files silcd/server.c and lib/silcclient/client.c.
3920 * Added `hash' field to the SilcClientConnection to include
3921 the hash function negotiated in the SKE protocol.
3923 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3924 to set the channel founder authentication data. A client can
3925 claim the founder rights later by providing the authentication
3926 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3927 This way the channel founder can regain the channel founder
3928 privileges even it is left the channel. This works only on
3929 local server and the client must be connected to the same
3930 server to be able to regain the founder rights. Updated the
3931 protocol specs accordingly.
3933 Added support to the CMODE command in the client to set the
3934 founder auth data. Read the README to see how to set it.
3936 Added support to the CUMODE command to claim the founder
3937 rights. Read the README to see how to do it.
3939 Added support for the founder authentication to the Channel
3940 Entry in the server. Affected file silcd/idlist.h.
3942 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3943 server's CMODE command. Affected file silcd/command.c.
3945 * Added the following new functions into lib/silccore/silcauth.[ch]:
3946 silc_auth_get_method and silc_auth_get_data.
3948 * The server now saves the remote hosts public key to the
3949 SilcIDListData pointer. Affected file silcd/protocol.c.
3951 * The normal server now does not remove the channel entry from
3952 the cache if the founder authentication data is set. It used
3953 to remove it if the founder was the last one on the channel on
3954 the server and left the channel. The auth data is saved and
3955 if the channel is re-joined later the old entry is used with
3956 the old auth data. Affected files silcd/command_reply.c and
3959 * Removed the `pkcs' field from the SilcIDListData structure
3960 in the server; it is not used. Affected file silcd/idlist.h.
3962 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Fixed packet processing on slow links. Partial packets were
3965 never re-processed because the incoming data buffer was cleared
3966 by the application. Application must not directly clear the
3967 sock->inbuf, the packet processing routines handle it. Fixed
3968 this in client library and in server.
3970 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3972 * Fixed the WHOIS and IDENTIFY send reply function to really
3973 check whether to send list or just one entry. Affected file
3976 * Cleaned up the LEAVE command's channel key distribution. The
3977 affected file silcd/command.c.
3979 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3980 can enforce the channel mode as well. In that case the ID
3981 includes the ID of the server. The code now enforces the
3982 mode change if the router have different mode than the server.
3984 * The notify client operation with CMODE_CHANGE notify can now
3985 return NULL client_entry pointer if the CMODE was not changed
3986 by client. Application must check for this.
3988 * Added <Server ID> argument to INFO command to support server
3989 info fetching by Server ID.
3991 * Added silc_server_announce_get_channel_users to get assembled
3992 packets of channel users of the specified channel. Affected
3993 file silcd/server.[ch].
3995 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3996 was freed underneath the ID Cache.
3998 * Re-announce clients when the server received CHANNEL_CHANGE
3999 notify from the router. Affected file silcd/packet_send.c.
4001 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4004 crashed since it did not handle the fact that there is no cipher
4005 called "3" and didn't check the error condition. Now fixed.
4007 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4008 flag. It can be used to send message requests.
4010 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Implemented the RESTART command in the client.
4014 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4015 notice type messages. Added notice printing to the user
4018 * The channel keys are not re-generated if the channel's mode
4019 is PRIVKEY, ie private key on the channel exists. Affected
4020 files silcd/server.c and silcd/command.c.
4022 * Fixed a little bug in channel message delivery when channel
4023 private keys are set in the server. Affected file is
4024 silcd/packet_send.c.
4026 * Changed the setting on channel->on_channel = TRUE from the
4027 silc_client_save_channel_key to the JOIN command reply. The
4028 key payload is not received if the private channel key is set.
4029 Affected file lib/silcclient/command_reply.c and the
4030 lib/silcclient/client_channel.c.
4032 * When the CMODE_CHANGE notify is sent and the channel private
4033 key mode is removed the channel key must be re-generated in
4034 other cells as well. Added this support for the router in the
4035 silcd/packet_receive.c.
4037 * Added new local command NOTICE to send notice message on
4038 channel. Affected file silc/local_command.[ch].
4040 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added new local command ME to the client. It is used to send
4043 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4044 some action. Affected file silc/local_command.[ch].
4046 * Changed channel_message and private_message client operations
4047 to deliver the message flags to the application. Added also
4048 the `flags' arguments to the silc_client_send_channel_message
4049 and silc_client_send_private_message functions. Affected file
4052 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Redefined the Private Message Payload to support private message
4055 keys and to support the new private message flags. Updated
4056 the protocol specs. Flags makes it possible to have for example
4057 CTCP style messages.
4059 * Added new type SilcPrivateMessagePayload and defined an API
4060 for it in the lib/silcclient/silcprivate.[ch].
4062 * Tested private message private keys successfully. Tested the
4063 private message key set, unset and list commands with the new
4066 * Redefined the Channel Message Payload to include the channel
4067 message flags (equal with private message flags) to support
4068 for example CTCP style messages.
4070 * Defined some of the message (for channel and private message)
4071 flags. Updated the protocol specs and added the flags to the
4072 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4074 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Added SilcKeyAgreementStatus type to the key agreement routines
4077 to indicate the current status and error if one occured.
4078 The status types are defined in the lib/silcclient/silcapi.h.
4080 * Added new local command KEY that is used to set and unset private
4081 keys for channels, set and unset private keys for private messages
4082 with remote clients and to send key agreement requests and
4083 negotiate the key agreement protocol with remote client. The
4084 key agreement is supported only to negotiate private message keys,
4085 it currently cannot be used to negotiate private keys for channels,
4086 as it is not convenient for that purpose.
4088 * Fixed a minor pending callback setting bug in the function
4089 silc_client_get_client_by_id_resolve, now the function works.
4090 Affected file lib/silcclient/idlist.c.
4092 * Added function silc_net_get_local_port to get local bound
4093 port by socket. Added to lib/silcutil/silcnet.[ch].
4095 * Added `sockets' and `sockets_count' fields to the SilcClient
4096 object. They hold the sockets of the listenning sockets in
4097 the client. Listenning sockets may be for example the key
4098 agreement server. Affected file lib/silcclient/client.[ch].
4099 Added functions the silc_client_add_socket and the
4100 silc_client_del_socket. They are exported to the application
4103 * Added ~./silc/clientkeys to support other client's public keys.
4105 * Renamed verify_server_key client operation to verify_public_key
4106 and added one argument to indicate the type of the connection
4107 (server, client etc.).
4109 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Added silc_server_connection_auth_request to handle the
4112 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4113 silcd/packet_receive.[ch].
4115 * Added silc_server_send_connection_auth_request into the
4116 silcd/packet_send.c to send the connection auth request packet.
4118 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4121 * Fixed the public key authentication in responder side in the
4122 server. The `auth_data' pointer includes the SilcPublicKey
4123 not the path to the public key. Affected file silcd/protocol.c.
4125 * Implemented the public key authentication in the initiator side
4126 in the server. Affected file silcd/protocol.c.
4128 * Removed the [RedirectClient] config section from the server
4129 configuration. Is not needed and I don't want to implement it.
4131 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Cleaned up the CMODE command in the server. It now works
4134 correctly and supports all the modes defined in the protocol.
4135 Affected file is silcd/command.c.
4137 * Added `hmac_name' field to the SilcChannelEntry in the server
4138 to hold the default HMAC of the channel. It can be set when
4139 creating the channel (with JOIN command). Affected files
4142 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4143 type to indicate the change of the current cipher and hmac
4144 on the channel. Client can safely ignore the <cipher> argument
4145 (if it chooses to do so) since the CHANNEL_KEY packet will
4146 force the channel key change anyway. The <hmac> argument is
4147 important since the client is responsible of setting the new
4148 HMAC and the hmac key into use.
4150 * Fixed the CMODE command in the client library as well.
4152 * Tested CMODE command in router environment successfully.
4154 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Show the version of the remote client (or server) when connecting
4157 to the server. It is logged to the log file. Affected file
4158 is silcd/protocol.c.
4160 * Fixed the KILLED notify handling in the client library. The
4161 client must be removed from all channels when receiving the
4164 Also, do not remove the client entry when giving the KILL
4165 command but when the KILLED notify is received.
4167 * Removed silc_idlist_find_client_by_nickname from the server.
4168 Not needed anymore. Affected files silcd/idlist.[ch].
4170 * Implemented the CHANNEL_CHANGE notify type handling to the
4171 server. Affected file silcd/server.c.
4175 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added silc_server_send_notify_invite to send the INVITE
4178 notify between routers.
4180 * Implemented the INVITE command correctly to the server.
4182 * Implemented the INVITE notify type handling in the server.
4184 * Implemented the INVITE command to the client library and on the
4187 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Added function silc_server_get_client_resolve to find the
4190 client entry by ID from all ID lists and then resolve it
4191 (using WHOIS) if it cannot be found. Affected file is
4194 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Implemented the BAN command to the client library.
4198 * The JOIN command in the server now checks the invite list
4201 * Changed the silc_command_reply_payload_encode_va and the
4202 silc_command_payload_encode_va to support that if argument is
4203 NULL it ignores and checks the next argument. Affected file
4204 lib/silccore/silccommand.c.
4206 * Added silc_server_send_notify_ban to send the BAN notify
4207 type between routers.
4209 * Chaned the silc_notify_payload_encode to support that if
4210 argument is NULL it ignores and checks the next argument.
4211 Affected file lib/silccore/silcnotify.c.
4213 * Tested ban lists in router environment successfully.
4215 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Implemented BAN command to the server, in silcd/command.[ch].
4219 * Removed the BAN and INVITE_LIST modes from the CMODE command
4222 * Added function silc_string_match to regex match two strings.
4223 Affected files lib/silcutil/silcutil.[ch].
4225 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Redefined parts of the SilcChannelEntry in the server to support
4228 the new ban and invite lists.
4230 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Redefined the INVITE command. The same command can be used to
4233 invite individuals to the channel but also to manage the invite
4234 list of the channel (to add to and remove from the invite list).
4235 Updated the protocol specs.
4237 * Added new command SILC_COMMAND_BAN that can be used to manage
4238 the ban list of the channel. Updated the protocol specs.
4240 * Removed the channel modes: the SILC_CMODE_BAN and the
4241 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4242 in the CMODE command. The equivalent features are now available
4243 using INVITE and BAN commands. Updated the protocol specs.
4245 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4246 in the network about change in the current ban list. The notify
4247 type is not used by the client.
4249 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4250 support the invite lists.
4252 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Added new function silc_string_regexify that converts string
4255 including wildcard characters into regex string that can
4256 be used by the GNU regex library. Added into the file
4257 lib/silcutil/silcutil.[ch].
4259 Added silc_string_regex_combine to combine to regex strings
4260 into one so that they can be used as one regex string by
4261 the GNU regex library. Added into the file
4262 lib/silcutil/silcutil.[ch].
4264 Added silc_string_regex_match to match two strings. It returns
4265 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4267 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Imported GNU regex to the soruce tree into lib/contrib.
4270 Fixed some compiler warning from the regex.c.
4272 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Fixed MOTD command in the server to work in router environment.
4276 * Fixed the MOTD command in the client library to support
4277 the server argument in the command.
4279 * Added `nickname_len' argument to the silc_idlist_add_client
4280 in the server, as the `nickname' argument may be binary data
4283 * Added silc_idlist_get_channels to return all channels from
4286 * Implemented LIST command to the server. Affected file is
4289 * Implemented the LIST command to the client library and on the
4292 * Added [<user count>] argument to the LIST command reply.
4293 With private channels the user count is not shown.
4295 * Updated TODO and README.
4297 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * The client entry's data.registered must be TRUE even with
4300 global client entry on global client list. The data.registered
4301 is used to check whether the client is anymore in the network,
4302 for example with WHOWAS command so it must be valid.
4304 * Fixed the WHOWAS command in the server. It now actually works
4305 in router environment. Added function into silcd/command_reply.c
4306 silc_server_command_reply_whowas_save.
4308 * Added silc_idlist_purge function to the silcd/idlist.c
4309 to periodically purge the ID Cache.
4311 * Fixed INFO command in the server. It works now in router
4312 environment. Added <server name> argument to the INFO command
4313 reply. Updated the protocol specs.
4315 * Fixed minor bug in silc_idcache_purge to not purge if the
4316 expire value is zero.
4318 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4319 they were buggy because of the WHOWAS information.
4321 * Fixed local command MSG to handle the async resolving of
4322 the remote client properly. It used to fail the first MSG.
4323 Affected file silc/local_command.c.
4325 * Added `data_len' field to SilcIDCache context.
4327 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Update TODO. Todo in commands in the server.
4331 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4334 used by routers as broadcast packet to inform other routers
4335 about the changed user mode.
4337 Implemented the notify handling in the server. Affected file is
4338 silcd/packet_receive.c. Added the function
4339 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4341 * Added new generic Channel Payload and deprecated the New Channel
4342 Payload. The New Channel Payload is now the generic Channel
4345 * Added new argument `mode' to the silc_server_send_new_channel
4346 as it is required in the Channel Payload now.
4348 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4349 and created a new and real SilChannelPayload to represent the
4350 new generic Channel Payload. Implemented the encode/decode
4351 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4353 * Added silc_server_get_client_channel_list to return the list
4354 of channels the client has joined for WHOIS command reply.
4355 Affected file silcd/server.[ch].
4357 * Implemented the channel list sending in the WHOIS command reply
4358 in server and in the client.
4360 Implemented the channel list displaying on the user interface
4361 as well. Affected file silc/client_ops.c.
4363 * Added silc_channel_payload_parse_list to parse list of Channel
4364 Payloads. It returns SilcDList list of SilcChannelPayloads.
4365 Client for example can use this function to parse the list of
4366 channels it receives in the WHOIS command reply. The caller
4367 must free the list by calling silc_channel_payload_list_free.
4368 Affected files lib/silccore/silcchannel.[ch].
4370 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Added one new argument <user mode> to the WHOIS command reply
4373 to return the mode of the user in SILC. Updated the protocol
4376 Implemented it to the server and client.
4378 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Fixed the mode printing on the user interface on joining.
4381 Affected file silc/client_ops.c.
4383 * Implemented the UMODE command and user modes in general to the
4384 client library and to the user interface.
4386 * Implemented the UMODE command to the server.
4388 * The server now sends UNKNOWN_COMMAND error status if client sends
4389 unknown command. Affected file silcd/command.c.
4391 * All server commands now handle the command identifier the right
4392 way when sending the command reply to the client. The client can
4393 use to identify the command replies with the identifier.
4395 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added silc_server_get_client_route to resolve the route to
4398 the client indicated by the client ID. Affected file is
4401 * Added silc_server_relay_packet as general function to relay
4402 packet to arbitrary destination. This deprecates functions
4403 like _send_private_message_key, _relay_notify etc. Affected
4404 file is silcd/packet_send.[ch].
4406 Removed silc_server_send_key_agreement,
4407 silc_server_send_private_message_key and
4408 silc_server_packet_relay_notify functions from the file
4409 silcd/packet_send.[ch].
4413 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4414 server. Affected file silcd/packet_receive.[ch].
4416 * Implemented the KILL command to the client. Implemented the
4417 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4418 Affected files lib/silcclient/command[_reply].c and
4419 lib/silcclient/client_notify.c. Implemented the KILL notify
4420 printing in the user inteface.
4422 * Fixed a lot silc_parse_nick memory leaks from the client
4423 library in the file lib/silcclient/command.c.
4425 * Changed the silc_server_send_notify_on_channels's `sender'
4426 argument from SilcSocketConnection to SilcClientEntry to
4427 check the sender as entry and not as connection object and not
4428 to send to the client provided as argument. The affected file
4429 is silcd/packet_send.[ch].
4431 * The notify packets that are destined directly to the client used
4432 to not to be processed by the server. Now changed that and the
4433 server processes all notify packets. After relaying the packet
4434 to the client the notify packet is processed in the server.
4436 * The silc_server_free_client_data now checks whether there is
4437 pending outgoing traffic for the client and purges the data to
4438 the network before removing the client entry.
4440 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4443 an client is killed from the SILC Network. Updated the protocol
4446 Added new function silc_server_send_notify_killed to the
4447 silcd/packet_send.[ch].
4449 * Added function silc_server_packet_relay_notify to relay notify
4450 packets that are destined directly to a client. In this case
4451 the server does not process the notify packets but merely relays
4452 it to the client. Affected file silcd/packet_send.[ch].
4454 Added also silc_server_packet_process_relay_notify to check
4455 whereto relay the notify. Affected file is
4456 silcd/packet_receive.[ch].
4458 * Implemented the KILL command to the server.
4462 * Added the backup schema desgined last fall to the protocol
4463 specs for everyone to see. The specification is in the
4464 *-spec-xx.txt draft and the packet type definitions for the
4465 backup routers is in *-pp-xx.txt draft. Thusly, added also
4466 new packet type SILC_PACKET_CELL_ROUTERS.
4468 * A big security problem in the implementation discovered. The
4469 signoff of an client did not cause new channel key generation
4470 which it of course should've done. The channel keys must be
4471 always re-generated when client leaves (or signoffs) the channel.
4472 The silc_server_remove_from_channels funtion now handles
4473 the channel key re-generation.
4475 * Added `sender' argument to the silc_server_send_notify_on_channels
4476 to not to send the client provided as argument. Affected file
4477 silcd/packet_send.[ch].
4479 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Implemented OPER and SILCOPER commands into the server and
4484 * Added silc_auth_verify and silc_auth_verify_data to verify
4485 the authentication directly from the authentication payload.
4486 It supports verifying both passphrase and public key based
4487 authentication. Affected file lib/silccore/silcauth.[ch].
4489 * Added `hash' field to the SilcIDListData structure. It is the
4490 hash negotiated in the SKE protocol. Affected file is
4493 * Slight redesigning of the SilcAuthPayload handling routines.
4494 Do not send SilcPKCS but SilcPublicKey as argument.
4496 * Implemented the public key authentication support to the
4497 serverconfig. The public key is loaded from the provided path
4498 and saved as authentication data to void * pointer. Thus,
4499 changed the unsigned char *auth_data to void *auth_data;
4501 * Fixed SHUTDOWN command to send the reply before the server
4502 is shutdown. :) Affected file silcd/command.c.
4504 * Fixed fatal bug in CONNECT command. The hostname was invalid
4505 memory and server crashed. Affected file silcd/command.c.
4507 * Fixed fatal bug in CLOSE command. The server_entry became
4508 invalid but was referenced later in the command. Affected file
4511 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Fixed fatal bug in failure packet handling. Server ignored
4514 the failure and thus crashed when it came.
4518 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4521 that the command may be executed only once in (about) 2 seconds.
4522 The old SILC_CF_LAG flag is same but allows command bursts up
4523 to five before limiting.
4525 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4526 server code. Various commands now includes the CF_LAG_STRICT
4527 flag to disallow any kind of miss-use of the command.
4529 * Fixed the silc_buffer_unformat to not to allocate any data
4530 if the length of the data is zero. It used to allocate the
4531 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4533 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Changed the format of AdminConnection configuration section
4536 in the server. Added username of the admin to the format.
4537 Affected files silcd/serverconfig.[ch].
4539 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4540 to return admin configuration data by host, username and/or
4543 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Implemented WHOWAS command to the server. Added the functions:
4547 silc_server_command_whowas_parse,
4548 silc_server_command_whowas_send_reply,
4549 silc_server_command_whowas_from_client and
4550 silc_server_command_whowas_from_server
4552 * Added <Client ID> argument to the WHOWAS command reply. Updated
4553 the protocol specs accordingly.
4555 * Implemented WHOWAS command and command_reply to the client
4558 Implemented the WHOWAS printing on the user interface.
4560 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Added new argument to the WHOWAS command reply, the real name.
4563 It is an optional argument. Updated the protocol specs.
4565 * Added SilcIDCacheDestructor callback that is registered when
4566 the SilcIDCache is allocated. The callback is called when
4567 an cache entry in the ID Cache expires, or is purged from the
4568 cache. Added into lib/silccore/idcache.[ch].
4570 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4571 to destruct the client entries when the cache entry expires.
4572 Other ID Cache's in server and in the client library ignores
4575 * If the ID Cache entry's `expire' field is zero then the entry
4576 never expires. Added boolean `expire' argument to the
4577 silc_idcache_add function in the lib/silccore/idcache.[ch].
4578 If it is TRUE the default expiry value is used.
4580 * Added silc_server_free_client_data_timeout that is registered
4581 when client disconnects. By default for 5 minutes we preserve
4582 the client entry for history - for WHOWAS command.
4584 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Added support to the server to enforce that commands are not
4587 executed more than once in 2 seconds. If server receives
4588 commands from client more frequently, timeout is registered
4589 to process the commands. Affected file silcd/command.c.
4590 Added new function silc_server_command_process_timeout.
4592 * Changed NICK_NOTIFY handling in client library to check that
4593 if the client's nickname was changed, so there is no need to
4594 resolve anything from the server.
4596 * Removed error printing from the WHOIS and IDENTIFY commands.
4597 If error occurs then it is ignored silently in the client library.
4598 The application, however, may map the received error to
4599 human readable error string. The application currently maps
4600 the NO_SUCH_NICKNAME error to string.
4602 * Made the command status message public to the application. Moved
4603 them from lib/silcclient/command_reply.c to
4604 lib/silcclient/command_reply.h. The application can map the
4605 received command status to the string with the
4606 silc_client_command_status_message function.
4608 * Added check to the server to check that client's ID is same
4609 as the Source ID in the packet the client sent. They must
4612 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Added dist-bzip hook to the Makefile.am to make bzip2
4615 compressed distributions.
4617 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Server now enforces the maximum length for the nickname and
4620 the channel as protocol specification dictates. 128 bytes for
4621 nickname and 256 bytes for channel name.
4623 * Moved the WHOIS printing to the application. The client libary
4624 does not print out the WHOIS information anymore, the application
4625 must do it. Renamed silc_client_command_reply_whois_print to
4626 the silc_client_command_reply_whois_save.
4628 The client's idle time is also sent to the application now, and
4629 the idle is shown on screen.
4631 * Added silc_client_command_reply_identify_save to save the
4632 received IDENTIFY entries.
4634 * Do not check for channel private keys in message sending and
4635 reception if the channel does not have the PRIVKEY mode set.
4636 Affected file lib/silclient/client_channel.c.
4638 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4641 just surfaced after chaning the JOIN procedure.
4643 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added silc_client_get_clients_by_list to get client entries
4646 from Client ID list, that is returned for example by JOIN
4647 and USERS command replies. The application should use this
4648 function for example when JOIN command reply is received to
4649 resolve the clients already on the channel (library does not
4650 do that anymore as USERS command reply is not used in the JOIN
4651 procedure anymore). Affected files lib/silcclient/silcapi.h and
4652 lib/silcclient/idlist.c.
4654 * JOIN command reply and USERS command reply returns now SilcBuffer
4655 pointers instead of unsigned char pointers when returning
4656 the client list and mode list.
4658 * Added <Client ID> argument to the JOIN command reply, mainly
4659 for the server to identify for which client the command was
4660 originally sent. Updated protocol specs accordingly.
4662 * Added SilcDlist private_key pointer to the SilcChannelEntry
4663 in the client to support the channel private keys. Affected
4664 file is lib/silcclient/idlist.h.
4666 * Added SilcChannelPrivateKey argument to the function
4667 silc_client_send_channel_message so that application can choose
4668 to use specific private ke if it wants to. If it is not provided,
4669 the normal channel key is used, unless private keys are set.
4670 In this case the first (key that was added first) is used
4671 as the encryption key.
4673 * Implemented the support for channel private key handling.
4674 Implemented the following functions:
4676 silc_client_add_channel_private_key,
4677 silc_client_del_channel_private_keys,
4678 silc_client_del_channel_private_key,
4679 silc_client_list_channel_private_keys and
4680 silc_client_free_channel_private_keys
4682 Affected file lib/silcclient/client_channel.c.
4684 * Added the support for the private keys in the channel message
4685 sending and encryption and in the message reception and
4686 decryption. Affected funtions are
4687 silc_client_send_channel_message and silc_client_channel_message.
4689 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Added SKE's key verify callback to the client library's
4692 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4694 * Removed the statement that server (or router) must send USERS
4695 command reply when joining to the channel so that the client
4696 knows who are on the channel. Instead, the client list and
4697 client's mode list is now sent in the JOIN command reply to the
4698 client who joined channel. This is better solution.
4700 * Added function silc_server_get_users_on_channel and function
4701 silc_server_save_users_on_channel to the silcd/server.[ch].
4703 * Removed function silc_server_command_send_users from the
4706 * Do not show topic on the client library anymore. The topic is
4707 sent in the command reply notify to the application and the
4708 application must show the topic now.
4710 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Added client searching by nickname hash into the IDENTIFY and
4713 WHOIS commands in the server as they were clearly missing from
4714 them. Affected file is silcd/command.c.
4716 * Fixed a bug in private message receiving in the client library.
4717 The remote ID was freed and it wasn't supposed, now it is
4720 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Minor fix to the channel payload; allocate the data area, as it
4723 needs to be of specific length.
4725 * If the key agreement port is zero then the operating
4726 system will define the bound port. Affected files are
4727 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4729 * Added new function silc_channel_payload_decrypt into the file
4730 lib/silccore/silcchannel.[ch].
4732 * Moved the channel message etc, check from silc_packet_decrypt
4733 to applications. The library calls now a generic
4734 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4735 when the packet is either normal or special. This was done to
4736 allow more wide range of checking that was not allowed when
4737 the code was in library. Now applications can do virtually any
4738 checks to the packet and return to the library the decision how
4739 the packet should be processed. Affected files are
4740 lib/silccore/silcpacket.[ch].
4742 Added silc_server_packet_decrypt_check to the server and
4743 silc_client_packet_decrypt_check to the client library.
4745 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4746 to send with specified source and destination information.
4748 * Channel message delivery between routers was broken after the
4749 channel key distribution was fixed earlier. The channel key
4750 was used be to distributed to other routers as well which is not
4751 allowed by the protocol. Now this is fixed and channel keys
4752 really are cell specific and the channel message delivery between
4753 routers comply with the protocol specification.
4755 * Fixed various commands in server to check also the global list
4756 for the channel entry and not just the local list. The affected
4757 file silcd/command.c.
4759 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Added assert()s to buffer formatting and unformatting routines
4762 to assert (if --enable-debug) when error occurs. Affected
4763 file: lib/silcutil/silcbuffmt.c.
4765 * Changed to auto-reconnect to check whether the remote host is
4766 router and register the re-connect timeout if it is. It used
4767 to check that whether we are normal server, but router must do
4768 auto-reconnect with another router as well. Affected file
4771 * Removed the [<key len>] option from CMODE command as the cipher
4772 name decides the key length, nowadays. See the defined ciphers
4773 from the protocol specification.
4775 * Added [<hmac>] option to the CMODE command to define the HMAC
4776 for the channel. Added SILC_CMODE_HMAC channel mode.
4778 * Added [<hmac>] option for the JOIN command so that user can
4779 select which HMAC is used to compute the MACs of the channel
4782 * Added Hmac field to the Channel Message Payload. The integrity
4783 of plaintext channel messages are now protected by computing
4784 MAC of the message and attaching the MAC to the payload. The
4785 MAC is encrypted. Now, it is clear that this causes some
4786 overhead to the size of the packet but rationale for this is that
4787 now the receiver can verify whether the channel message decrypted
4788 correctly and also when private keys are set for the channel the
4789 receiver can decrypt the packet with several keys and check from
4790 the MAC which key decrypted the message correctly.
4792 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4793 lib/silccrypt/silccipher.[ch].
4795 * Added silc_hash_len to return the digest length into the
4796 lib/silcrypt/silchash.[ch].
4798 * Rewrote parts of Silc Channel Payload interface in the
4799 lib/silccore/silcchannel.[ch]. The encode function now also
4800 encrypts the packet and parse function decrypts it.
4802 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Fixed a minor formatting bug in the SKE's key material processing.
4805 It actually might have processed the keys wrong way resulting
4808 * Redefined the mandatory HMAC algorithms and added new algorithms.
4809 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4810 and hmac-md5 truncated to 96 bits. The mandatory is now
4811 hmac-sha1-96. Rest are optional (including the one that used
4812 to be mandatory). Rationale for this is that the truncated HMAC
4813 length is sufficient from security point of view and can actually
4814 make the attack against the HMAC harder. Also, the truncated
4815 HMAC causes less overhead to the packets. See the RFC2104 for
4818 * Added new [hmac] configuration section. The SKE used to use
4819 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4820 is of course wrong. The official names that must be proposed in
4821 the SKE are the ones defined in the protocol specification
4822 (hmac-sha1-96 for example). The user can configure any hmac
4823 using any hash function configured in the [hash] section. At
4824 least, the mandatory must be configured.
4826 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4828 * Added HMAC list to the SKE proposal list. It has now both
4829 hash algorithm list and HMAC list. This makes the protocol
4830 incompatible with previous versions. The SKE now seems to work
4831 the way it is supposed to work, for the first time actually.
4833 * Defined plain Hash algorithms to the protocol specification.
4836 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Implemented support for key agreement packets into the server.
4839 Added functions silc_server_key_agreement and
4840 silc_server_send_key_agreement. Other than these functions,
4841 server has nothing to do with this packet.
4843 * Added support for private message key packets into the server.
4844 Added functions silc_server_private_message_key and
4845 silc_server_send_private_message_key.
4849 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4850 called in the protocol's final callback instead in the END
4851 protocol state. This makes a little more sense and in the same
4852 time in client we can use the same protocol routines for normal
4853 key exchange and to key agreement packet handling as well.
4855 * Added to both client's and server's KE protocol context the
4856 SilcSKEKeyMaterial pointer to save the key material. We will
4857 bring the key material to the protocol's final callback by doing
4858 this. The final callback must free the key material.
4860 * Added SKE's packet_send callback into client's KE protocol
4861 context so that the caller can choose what packet sending function
4862 is used. This way we can use different packet sending when
4863 doing normal SKE when doing key agreement packet handling (in
4864 the key agreement packet handling we do not want to encrypt
4867 * Implemented the responder side of the key agreement routines
4868 in the client. The client can now bind to specified port and
4869 accept incoming key negotiation. The key material is passed
4870 to the application after the protocol is over.
4872 * Implemented the processing of incoming Key Agreement packet
4873 in the client. Added function silc_client_key_agreement to
4876 * Implemented the intiator side of the key agreement routines
4877 in the client. The client can now initiate key agreement with
4878 another remote client. The key material is passed to the
4879 application after the protocol is over.
4881 * Created client_keyagr.c to include all the key agreement
4884 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4885 SILC_TASK_CALLBACK except that it is not static.
4887 * Created client_notify.c and moved the Notify packet handling
4888 from the client.[ch] into that file.
4890 * Created client_prvmsg.c and moved all private message and
4891 private message key routines from the client.[ch] into that file.
4893 * Create client_channel.c and moved all channel message and
4894 channel private key routines from the client.[ch] into that file.
4896 * Changed silc_client_get_client_by_id_resolve to resolve with
4897 WHOIS command instead of IDENTIFY command, in the file
4898 lib/silclient/idlist.c.
4900 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Implemented the SKE's responder side to the Client library.
4904 * When FAILURE is received to the protocol do not trust it
4905 blindly. Register a timeout to wait whether the remote closes
4906 the connection as it should do it, only after that process the
4907 actual failure. This was changed to both client and server.
4909 * Added client_internal.h to include some of the structures
4910 there instead of client.h in lib/silcclient/.
4912 * Added function silc_task_unregister_by_callback to unregister
4913 timeouts by the callback function.
4915 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Some "Incomplete WHOIS info" errors has been appearing on the
4918 log files. Took away the entry->userinfo check from WHOIS
4919 reply sending. The entry->userinfo is now " " if client did not
4920 provide one. I thought this was fixed earlier but something
4921 is wrong still. Let's see if the error still appears.
4923 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Fixed a minor bug in the login when the channel key is
4926 re-generated in the server. It used to generate the key in
4927 wrong order and thus caused problems in the channel traffic.
4929 * Fixed a minor bug in channel key distsribution after
4930 KICK command. The key was not sent to the router even though
4933 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added silc_ske_process_key_material_data as generic routine
4936 to process any key material as the SILC protocol dictates. The
4937 function is used by the actual SKE library but can be used by
4938 applications as well. This relates to the private message keys
4939 and the channel private keys since they must be processed the
4940 same way the normal SILC session keys. The protocol dictates
4941 this. Affected files: lib/silcske/silcske.[ch].
4943 Added also silc_ske_free_key_material to free the
4944 SilcSKEKeyMaterial structure.
4946 * Defined silc_cipher_set_key function to set the key for
4947 cipher without using the object's method function. The affected
4948 files: lib/silccrypt/silccipher.[ch].
4950 * Implemented silc silc_client_add_private_message_key,
4951 silc_client_add_private_message_key_ske,
4952 silc_client_del_private_message_key,
4953 silc_client_list_private_message_keys and
4954 silc_client_free_private_message_keys functions in the
4957 Added functions silc_client_send_private_message_key to send
4958 the Private Message Key payload and silc_client_private_message_key
4959 to handle incoming Private Message Key payload.
4961 * Added Cipher field to the Private Message Key payload to set
4962 the cipher to be used. If ignored, the default cipher defined
4963 in the SILC protocol (aes-256-cbc) is used.
4965 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Removed lib/silcclient/ops.h file.
4969 Redefined parts of the SILC Client Library API. Created new
4970 file silcapi.h that deprecates the ops.h file and defines the
4971 published Client Library API. Defined also private message key
4972 API and channel private key API into the file.
4974 This is the file that the application must include from the
4975 SILC Client Library. Other files need not be included by
4976 the application anymore.
4978 * Added new key_agreement client operation callback and also
4979 defined the Key Agreement library API for the application.
4981 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4984 is used by clients to request key negotiation between another
4985 client in the SILC network. If the negotiation is started it
4986 is performed using the SKE protocol. The result of the
4987 negotiation, the secret key material, can be used for example
4988 as private message key.
4990 Implemented the Key Agreement payload into the files
4991 lib/silccore/silauth.[ch].
4993 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4995 * Redefined ciphers for the SILC protocol. Added some new ciphers
4996 and defined the key lengths for the algorithms. Changed the
4997 code accordingly. The default key length is now 256 bits.
4999 * Fixed SKE key distribution function silc_ske_process_key_material
5000 when the key length is more than 128 bits. The default key
5001 length in SILC is now 256 bits.
5003 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5004 to indicate unsupported algorithm.
5006 * Renamed rijndael.c to aes.c and all functions as well.
5008 * Fixed a long standing channel key setting bug in client library.
5009 Weird that it has never surfaced before.
5011 * Fixed bug in channel deletion. If the entire channel is removed
5012 then it must also delete the references of the channel entry
5013 from the client's channel list as the client's channel entry and
5014 the channel's client entry share same memory.
5016 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Implemented CONNECT and SHUTDOWN commands in the client.
5020 * Implemented CLOSE command to the client.
5022 * Added the function silc_idlist_find_server_by_name into the
5023 files silcd/idlist.[ch].
5025 Added the function silc_idlist_find_server_by_conn into the
5026 files silcd/idlist.[ch].
5028 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * DIE command was renamed to SHUTDOWN. Updated the both code
5033 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5034 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5036 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5039 * Added function silc_server_create_connection function to create
5040 connection to remote router. My server implementation actually
5041 does not allow router to connect to normal server (it expects
5042 that normal server always initiates the connection to the router)
5043 so the CONNECT command is only good for connecting to another
5046 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5049 or some other client was kicked from the channel.
5051 Implemented the handling of the notify type to both client
5054 Implemented silc_server_send_notify_kicked to send the KICKED
5055 notify. It is used to send it to the server's primary router.
5057 * Implemented the KICK command into server and client.
5059 * Added `query' argument to the silc_idlist_get_client function
5060 to indicate whether to query the client from server or not if
5063 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5064 to indicate that the client is not channel founder.
5068 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Removed the rng context from SilcPacketContext structure and
5071 changed that the packet routine uses the Global RNG API.
5073 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Added support for quit message that client can "leave" on the
5076 channel when it quits the SILC. It is ditributed inside the
5077 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5079 Added silc_server_free_client_data that will take the
5080 signoff message as argument.
5082 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5084 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Updated parts of the protocol specification to keep it up
5089 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5092 payloads in one packet.
5094 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5095 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5096 use now the new List flag.
5098 * Also deprecated the following packet types: REPLACE_ID,
5099 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5101 * Added list support for Notify packet in server.
5103 * Added silc_server_send_notify_channel_change to send the
5104 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5105 the silc_server_send_replace_id.
5107 * Added silc_server_send_notify_nick_change to send the
5108 NICK_CHANGE notify type. Deprecates the function
5109 silc_server_send_replace_id.
5111 * Added silc_server_send_notify_join to send the JOIN notify type.
5112 Deprecates the function silc_server_send_new_channel_user.
5114 * Added silc_server_send_notify_leave to send LEAVE notify type.
5115 Deprecates the function silc_server_send_remove_channel_user.
5117 * Added silc_server_send_notify_cmode and
5118 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5119 types. Deprecates the silc_server_send_set_mode function.
5121 * Added SERVER_SIGNOFF notify type to indicate that server has
5122 quit. This means that all clients on the channel from that
5123 server will drop. This can be also used when netsplit happens.
5125 Deprecated REMOVE_ID packet type since it is not needed anymore
5128 Added silc_server_send_notify_server_signoff to send the
5129 SERVER_SIGNOFF notify type. Deprecates the function
5130 silc_server_send_remove_id.
5132 Added also silc_server_send_notify_signoff to send the
5133 SIGNOFF notify type.
5135 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5136 SILC protocol from this day on. Changed the protocol
5137 specification as well.
5139 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5140 notify type. It is used between routers to notify about
5141 topic changes on a channel.
5143 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5146 * Partly updated the protocol specification to comply with the
5147 changes now made. It is still though a bit outdated.
5149 * The JOIN notify type now takes one extra argument <Channel ID>.
5150 The packet used to be destined to the channel but now the
5151 JOIN type may be sent as list thus it is impossible to
5152 destine it to any specific channel. By adding this argument
5153 it is again possible.
5155 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5157 * Added CREDITS file. The CHANGES and CREDITS file will appear
5158 in the distribution as well.
5160 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5163 types in the server's silcd/packet_receive.c.
5165 * Implemented CMODE and CUMODE to work in router environment.
5167 * Fixed minor encoding and decoding buglet from the
5168 lib/silccore/silcmode.c.
5170 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5173 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5175 * Changed all SilcConfigServer* and silc_config_server* to
5176 SilcServerConfig* and silc_server_config*, respectively.
5179 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Associated the ID (client or server ID) to the Authentication
5182 Payload to avoid any possibility of forging. Updated the
5183 protocol specification and the code accordingly.
5185 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5187 * The RSA key length is now save to the RsaKey context in the
5188 key generation process in lib/silccrypt/rsa.c. The key length
5189 is now used to figure out the maximum size of the block allowed
5190 to be encrypted/signed.
5192 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5193 is equivalent to the silc_mp_mp2bin but does not allocate any
5196 * Changed silc_mp_mp2bin API to take length argument. If it is
5197 non-zero then the buffer is allocated that large. If zero, then
5198 the size is approximated using silc_mp_sizeinbase, which however
5201 * Created Global RNG API which is global RNG that application can
5202 initialize. After initializing, any routine anywhere in the
5203 code (including library) can use RNG without allocating a new
5204 RNG object. This was done to allow this sort of use of the
5205 RNG in code that has no chance to allocate RNG object. All
5206 applications currently allocate this and many routines in the
5207 library use this. Affected file lib/silccrypt/silcrng.[ch].
5209 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5210 it to use the Global RNG API.
5212 * Defined Authentication Payload into protocol specification that
5213 is used during SILC session to authenticate entities. It is
5214 used for example by client to authenticate itself to the server
5215 to obtain server operator privileges.
5217 Implemented this payload into the lib/silccore/silcauth.[ch].
5218 Implemented also routines for public key based authentication
5219 as the new protocol specification dictates.
5221 Moved definitions of different authentication methods from
5222 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5224 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5225 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5226 silc_pkcs_verify_with_hash functions into the file
5227 lib/silccrypt/silcpkcs.[ch].
5229 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * The client entry's userinfo pointer must be always valid.
5232 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5233 will fail since it requires the userinfo. Now, the userinfo
5234 is allocated as "" if actual userinfo does not exist. Actually,
5235 it must exist and it is totally Ok to drop client connections
5236 that does not announce the userinfo. However, we will make
5237 this workaround for now.
5239 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5240 to return the remote port by socket.
5242 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5245 SILC_SERVER_PENDING_EXEC and added an new macro
5246 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5247 data or when error occurs while processing the pending command.
5249 Added new argument `destructor' into silc_server_command_pending
5250 and to the SilcServerCommandPending object. This destructor is
5251 now called after calling the pending callback or if error occurs
5252 immediately. If error occurs the actual pending callback won't
5253 be called at all - only the destructor. The destructor may be
5254 NULL if destructor is not needed.
5256 All this applies for client library code as well. Similar
5257 changes were made there as well for the pending commands.
5259 In the client, the application must now allocate the
5260 SilcClientCommandContext with the silc_client_command_alloc
5263 * Added reference counter to the SilcServerCommandContext. Added
5264 function silc_server_command_alloc and silc_server_command_dup
5267 Same type of functions added to the client library for the same
5270 * Removed the cmd_ident from IDListData away since it is now
5271 global for all connections. It is the command identifier used
5272 in command sending and with pending commands. The affected file
5275 * Added reference counter to the SilcSocketConnection objecet to
5276 indicate the usage count of the object. The object won't be
5277 freed untill the reference counter hits zero. Currently only
5278 server uses this, and client ignores it. The client must be
5279 set to use this too later. The affected files are
5280 lib/silccore/silcsockconn.[ch]. Added also the function
5281 silc_socket_dup to increase the reference counter.
5283 This was mainly added because it is possible that the socket
5284 is removed underneath of pending command or other async
5285 operation. Now it won't be free'd and proper DISCONNECTING
5286 flags, etc. can be set to avoid sending data to connection that
5287 is not valid anymore.
5289 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5290 the connection. After that it sets SILC_SET_DISCONNECTED.
5291 It is, however, possible that the socket data is not still freed.
5292 The silc_server_packet_process now checks that data is not
5293 read or written to connection that is DISCONNECTED. The socket
5294 get's freed when the reference counter hits zero.
5296 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Changed the client operation API: channel_message operation's
5299 `sender' is now the client entry of the sender, not the nickname
5300 and the `channel' is the channel entry, not the channel name.
5302 In the private_message operation the `sender' is now also the
5303 client entry of the sender not the nickname.
5305 Affected file is lib/silcclient/ops.h and all applications
5306 using the client operations.
5308 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5310 * Moved the calling of ops->connect() from connect_to_server_final
5311 into receive_new_id functin since that is the point when the
5312 client is actually allowed to send traffic to network. The
5313 affected file is lib/silcclient/client.c.
5315 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5318 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5319 (if needs broadcasting) instead of broadcasting the packets one
5320 by one which would make a burst in the network traffic.
5322 * Added `broadcast' argument to the functions in silcd/server.[ch]
5323 silc_server_create_new_channel[_with_id] to indicate whether
5324 to send New Channel packet to primary router.
5326 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Added new function into the silcd/server.[ch] files:
5329 silc_server_create_new_channel_with_id to create new channel with
5330 already existing Channel ID.
5332 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5333 lib/silccore/silcpacket.h. This packet is used t send list of
5334 Set Mode payloads inside one packet. Server uses this to set
5335 the modes for the channels and clients on those channels, that it
5336 announced to the router when it connected to it. The protocol
5337 specification has been updated accordingly.
5339 * The silc_server_new_channel did not handle the packet coming
5340 from normal server as it normally does not send that. However,
5341 when it announces its channels it does send it. Implemented
5342 the support for that.
5344 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5345 into the file lib/silccore/id.h.
5347 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Fixed memory leaks in the functions silc_idlist_del_client,
5350 silc_idlist_del_channel and silc_idlist_del_server in the file
5351 silcd/idlist.c. All of those leaked like a sieve.
5353 * Fixed some small memory leaks in the client's function
5354 silc_client_notify_by_server.
5356 * Added functions into silcd/server.c: silc_server_announce_clients,
5357 silc_server_announce_channels and silc_server_announce_server.
5358 These functions are used by normal and router server to announce
5359 to its primary router about clients, channels and servers (when
5360 router) that we own. This is done after we've connected to the
5363 These functions effectively implements the following packet types:
5364 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5365 and SILC_PACKET_NEW_ID_LIST.
5367 * Added new functions into the silcd/packet_receive.[ch]:
5368 silc_server_new_id_list, silc_server_new_channel_list and
5369 silc_server_new_channel_user_list to handle the incoming
5370 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5372 * Added support of changing Channel ID in the function
5373 silc_server_replace_id. If the server that announces a channel
5374 to the router already exists in the router (with same name but
5375 with different Channel ID), router is responsible to send
5376 Replace ID packet to the server and force the server to change
5377 the Channel ID to the one router has.
5379 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5380 client that the Channel ID has been changed by the router. The
5381 normal server sends this to the client. Client must start using
5382 the new Channel ID as the channel's ID.
5384 Implemented handling of this new type into lib/silcclient/client.c
5385 into the function silc_client_notify_by_server.
5387 * Added new function silc_idlist_replace_channel_id into the files
5388 silcd/idlist.[ch] to replace the Channel ID.
5390 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Call silc_server_command_identify_check always when processing
5393 the IDENTIFY command in silcd/command.c
5395 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5398 send keepalive packets. The packet can be sent by clients,
5399 servers and routers.
5401 Added function silc_socket_set_heartbeat into the file
5402 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5403 If not set, the heartbeat is not performed. The actual
5404 heartbeat is implemented in the low level socket connection
5405 library. However, application is responsible of actually
5408 Added silc_server_send_heartbeat to send the actual heartbeat
5409 packet into silcd/packet_send.[ch]. Server now performs
5410 keepalive with all connections.
5412 * Added silc_task_get_first function into lib/silcutil/silctask.c
5413 to return the timeout task with shortest timeout. There was a bug
5414 in task unregistration that caused problems. TODO has been
5415 updated to include that task system must be rewritten.
5417 * The client library will now resolve the client information when
5418 receiving JOIN notify from server for client that we know but
5419 have incomplete information.
5421 * Rewrote parts of silc_server_remove_from_channels and
5422 silc_server_remove_from_one_channel as they did not remove the
5423 channel in some circumstances even though they should've.
5425 * Encryption problem encountered in server:
5427 The LEAVE command used to send the Channel Key packet to the
5428 router immediately after generating it. However, the code
5429 had earlier sent Remove Channel user packet but not immediately,
5430 ie. it was put to queue. The order of packets in the router
5431 was that Channel Key packet was first and Remove Channel User
5432 packet was second, even though they were encrypted in the
5433 reverse order. For this reason, MAC check failed. Now, this
5434 is fixed by not sending the Channel Key packet immediately but
5435 putting it to queue. However, this is more fundamental problem:
5436 packets that are in queue should actually not be encrypted
5437 because packets that are sent immediately gets encrypted
5438 actually with wrong IV (and thus MAC check fails). So, packets
5439 that are in queue should be encrypted when they are sent to
5440 the wire and not when they put to the queue.
5442 However, the problem is that the current system has not been
5443 designed to work that way. Instead, the packet is encrypted
5444 as soon as possible and left to the queue. The queue is then
5445 just purged into wire. There won't be any fixes for this
5446 any time soon. So, the current semantic for packet sending
5449 o If you send packet to remote host and do not force the send
5450 (the packet will be in queue) then all subsequent packets to the
5451 same remote host must also be put to the queue. Only after the
5452 queue has been purged is it safe again to force the packet
5455 o If you send all packets immediately then it safe to send
5456 any of subsequent packets through the queue, however, after
5457 the first packet is put to queue then any subsequent packets
5458 must also be put to the queue.
5460 Follow these rules and everything works fine.
5462 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Added new function silc_server_remove_clients_by_server to
5465 remove all client entries from ID list when the server connection
5466 is lost. In this case it is also important to invalidate all
5467 client entires as they hold the invalid server entry. This
5468 fixes fatal bug when server has lost connection and will reconnect
5471 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Made some sanity checks to silc_server_daemonise like to check
5474 whether the requested user and group actually exists.
5476 * Added sanity check to SKE's silc_ske_responder_finish to check
5477 that the public and private key actually is valid.
5479 * Invalidate the client's nickname when receiving Replace ID
5480 packet and the Client ID is being replaced. This means that the
5481 server will query the nickname if someone needs it (client)
5484 * Sort the ID Cache in client library when the ID Cache data
5485 has changed (needs sorting).
5487 * Do not allow for SILC client to create several connections to
5488 several servers. The client does not support windows right now
5489 and generating multiple connections causes weird behaviour.
5491 Irssi-silc client does support windows and can handle several
5492 connections without problems, see: www.irssi.org and SILC plugin.
5494 * Fixed some places where client was added to the IDList. The
5495 rule of thumb is following (in order to get everything right):
5496 If the client is directly connected local client then the
5497 `connection' argument must be set and `router' argument must be
5498 NULL to silc_idlist_add_client function. If the client is not
5499 directly connected client then the `router' argument must
5500 bet set and the `connection' argument must be NULL to the
5501 silc_idlist_add_client function.
5503 * The funtion silc_server_packet_send_local_channel actually did
5504 not check whether the client was locally connected or not. It
5505 does that now. Fixed a bug related to LEAVE command.
5507 * Fixed Remove Channel User payload parsing bug in server's
5508 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5510 * The server's silc_server_save_channel_key now checks also the
5511 global ID list for the channel as it might not be in the local
5512 list. Fixed a bug related to LEAVE command.
5514 * Is this the end of the [<unknown>] buglet that has been lurking
5515 around for a long time? A little for loop fix in server's
5516 silc_server_command_whois_parse that is used by both IDENTIFY
5517 and WHOIS command. At least, this was a clear bug and a cause
5518 of one type of [<unknown>] buglet.
5520 * WHOIS and IDENTIFY commands call the function
5521 silc_server_command_[whois/identify]_check function even if
5522 we are not router server.
5524 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5526 * Added --with-gmp configuration option. If set the GMP
5527 is always compiled in the SILC source tree. If not set then
5528 it is checked whether the system has the GMP3 installed. If
5529 it has then the GMP won't be compiled (the system's headers
5530 and library is used), if it doesn't have it then the GMP is
5531 compiled in the SILC source tree.
5533 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Changed RSA private exponent generation to what PKCS #1
5536 suggests. We try to find the smallest possible d by doing
5537 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5538 not security fix but optimization.
5540 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Added new config entry [Identity] to fork the server and run
5543 it as specific user and group. A patch from Bostik.
5545 * Imported Dotconf configuration library into lib/dotconf.
5546 This will be used to create the SILC configuration files later.
5547 It will appear in the distsribution after this commit.
5549 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * A big code auditing weekend happening. Auditing code for
5552 obvious mistakes, bugs and errors. Also, removing any code
5555 Removed files for being obsolete:
5557 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5558 inline in the file lib/silcutil/silcbuffer.h)
5560 o lib/silcutil/silcbufutil.c (the header has inline versions)
5562 Changed code to fix possible error conditions:
5564 o The buffer formatting routines now check that the destination
5565 buffer really has enough space to add the data. This applies for
5566 both buffer formatting and unformatting
5567 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5568 unformatting was changed to accomodate following rules:
5569 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5570 sent to the function while XXX_*STRING will not allocate or copy
5571 the data into the buffer. Instead it sets the pointer from the
5572 buffer into the pointer sent as argument (XXX_*STRING used to
5573 require that the pointer must be allocated already). This change
5574 makes this whole thing a bit more consistent and more optimized
5575 (note that the data returned in the unformatting with XXX_*STRING
5576 must not be freed now). The routines return now -1 on error.
5578 o Tried to find all code that use buffer_format and buffer_unformat
5579 and added return value checking to prevent formatting and
5580 especially unformatting errors and possible subsequent fatal
5583 o Changed ske->x and ske->KEY to mallocated pointers in
5584 lib/silcske/silcske.h. Fixed possible data and memory leak.
5586 o Added return value checking to all *_parse* functions. Fixed
5587 many memory leaks as well.
5589 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5590 so that buffer overflows would not happen. All code now also
5591 checks the return value as it can fail.
5593 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Added reconnection support to server if the normal server looses
5596 its connection to the router (for example if router is rebooted).
5597 The server performs normal reconnection strategy implemented
5598 to the server. Affected file silcd/server.c.
5600 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added new packet type SILC_PACKET_SET_MODE that is used to
5603 distribute the information about changed modes (for clients,
5604 channels and clients channel modes) to all routers in the
5605 network. Updated the protocol specification accordingly.
5607 Added functions into silcd/packet_send.c and
5608 silcd/packet_receive.c: silc_server_send_set_mode,
5609 silc_server_set_mode.
5611 Added new files silcmode.[ch] into lib/silccore that implements
5612 the encoding and decoding of Set Mode Payload. Added new type
5613 SilcSetModePayload. Moved the definitions of different modes
5614 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5616 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Oops, a little mistake in server's connection authentication
5619 protocol. The protocol is not ended with FAILURE but with
5620 SUCCESS if the authentication is Ok. :) Affected file is
5623 * Implemented NICK_CHANGE notify handling in server in the file
5624 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5625 the local clients on the channel. After the changing nickname
5626 in router environment snhould work and the [<unknown>] nickname
5627 should appear no more.
5629 The silc_server_replace_id function that receives the Replace ID
5630 payload now sends the NICK_CHANGE notify type also in the file
5631 silcd/packet_receive.c
5633 * Changed WHOIS and IDENTIFY command to support the maximum amount
5634 of arguments defined in protocol specs (3328 arguments). This
5635 fixed a bug that caused problems when there were more than three
5638 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Added extra parameter, command identifier, to the
5641 silc_client_send_command so that explicit command identifier
5644 Changed that ID list routines uses specific command identifier
5645 when sending WHOIS/IDENTIFY requests to the server so that they
5646 can be identified when the reply comes back.
5648 Affected files lib/silcclient/command.[ch],
5649 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5651 * Added `sender' argument to silc_server_packet_send_to_channel
5652 to indicaet the sender who originally sent the packet to us
5653 that we are now re-sending. Ignored if NULL. Affected file
5654 silcd/packet_send.[ch].
5656 * Added some server statistics support in silcd/server_internal.h
5657 SilcServerStatistics structure and around the server code. Also
5658 send some nice statistics information when client is connecting
5661 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Fixed channel ID decoding in server's JOIN command reply in
5664 silcd/command_reply.c
5666 * Fixed braodcasting of replace ID payload to not to send it if
5667 we are standalone server in silcd/packet_receive.c.
5669 * Fixed all channel message sending routines to not to send
5670 packets to clients that has router set, since they are routed
5671 separately in the same function earlier. Affects file
5672 silcd/packet_send.c and all channel packet sending functions.
5674 * In USERS reply, res_argv[i] are not allocated, the table
5675 is allocated. Thus changed that free the table, not its
5678 * In server's whois_check and identify_check if the client is
5679 locally connected do not send any WHOIS commands - they are not
5682 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Fixed some minor bugs in client when sending WHOIS command. The
5685 arguments was in wrong order.
5687 * Removed statis function add_to_channel from server in
5688 silcd/command.c that was previously used with the joining but
5691 * Tested USERS command in router environment successfully with two
5692 routers, two servers and two clients.
5694 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Reorganized the USERS command and command reply in client library
5697 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5698 When the command is given by user we register a pending command
5699 callback that will reprocess the command after the reply has been
5700 received from the server. When reprocessing the packet we then
5701 display the information. Thus, the USERS information is displayed
5702 now in the command callback instead of in the command reply
5703 callback. The processing of the command is same as previously
5704 when server has sent the command reply in the JOINing process.
5706 * Added to USERS command in silcd/command_reply.c to join the client,
5707 we didn't use to know about, to the channel after we've created
5708 a client entry for it. Also, for clienet we did know already still
5709 check whether it is on the channel or not and add it if not.
5711 * Removed silc_server_command_join_notify as the function and its
5714 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Changed the client's pending command handling to the same as the
5717 server's pending command handling. It is also now possible to
5718 execute command reply functions from other command reply
5719 function as the function callbacks for commands and command
5720 replies are one and same. The pending commands are not static
5721 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5722 in client connection context. Thus, pending commands are server
5723 connection specific as it is convenient.
5725 Changed the function silc_client_command_pending and
5726 silc_client_command_pending_del and added new function
5727 silc_client_command_pending_check. Removed the
5728 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5731 * Added cmd_ident, current command identifier, to the client
5732 connection context in lib/silcclient/client.h to keep track on
5733 command identifiers used in command sending. Client's command reply
5734 function handling now supports the mandatory command identifiers.
5736 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5737 funtions in client to fully support pending command callbacks.
5739 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5740 as one of the arguments to the application in the command reply
5743 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5744 before first releasing SILC but came back. Now it is removed again
5745 and should come back nomore. The FORWARDED flag was used only
5746 by the JOINing procedure by forwarding the command packet to router.
5747 Now, the JOINing procedure has been changed to more generic (due
5748 to various router environment issues) and FORWARDED is not needed
5749 anymore for anything. The protocol specification is yet to be
5752 Now, removed silc_server_packet_forward from server and the flag
5753 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5755 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Renamed NAMES command to USERS command. The NAMES was named that
5758 due to historical reasons. Now it is renamed. Also, rewrote
5759 parts of the USERS command. The nickname list is not sent anymore
5760 by the server. Only Client ID and mode lists are sent in the USERS
5761 command. Changed this also to the protocol specification.
5763 The client now resolves the names and stuff after it receives
5764 the USERS list from the server when joining to the channel.
5766 * WHOIS and IDENTIFY commands has been changed to support multiple
5767 Client ID's per command. One can now search for multiple users
5768 in the network by sending only one WHOIS or IDENTIFY command.
5769 Changed the code and the protocol specifications.
5771 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5772 uses silc_server_command_whois_parse to parse the request. */
5774 * If normal server, do not parse the WHOIS and IDENTIFY requests
5775 before sending it to the router. Saves some time.
5777 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Fixed JOIN command on client library. Wrong number of arguments
5780 used to crash the client.
5782 * Added silc_server_channel_has_global function to check whether
5783 channel has global users or not.
5785 * Added silc_server_channel_has_local function to check whether channel
5786 has locally connected clients on the channel.
5788 * The silc_server_remove_from_one_channel now checks whether the
5789 channel has global users or not after given client was removed from
5790 the channel. It also checks whether the channel has local clients
5791 on the channel anymore. If it does not have then the channel entry
5792 is removed as it is not needed anymore.
5794 * The silc_server_notify now checks on JOIN notify whether the joining
5795 client is one of locally connected or global. If it is global then
5796 the channel has now global users on the channel and that is marked
5797 to the channel entry. Also, it now saves the global client to
5798 global list who is joining and JOINs it to the channel. This is
5799 for normal server, that is.
5801 Changed silc_server_send_notify_on_channel,
5802 silc_server_packet_relay_to_channel and
5803 silc_server_packet_send_to_channel check if we are normal server
5804 and client has router set (ie. global client) do not send the
5805 message to that client, as it is already routed to our router.
5807 * Implemented LEAVE notify type handling in silc_server_notify
5810 * Tested LEAVE command in router environment successfully. Tested
5811 with two routers, two servers and two clients.
5815 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5817 * Implemented SIGNOFF notify type handling in silc_server_notify
5820 * silc_server_remove_id now removes the client entry from all channels
5821 it has joined and thusly sends SIGNOFF notify type.
5823 * Rewrote the NAMES list generation in server by removing two excess
5824 loops. The lists are created now inside one loop.
5826 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * silc_server_remove_channel_user checks now also global list
5829 for channel and client.
5831 * silc_server_new_channel_user checks now both local and global
5832 list for channel and client. Fixed a bug in client id decoding.
5833 Used to decode wrong buffer.
5835 * silc_server_channel_message checks now both local and global
5836 list for channel entry.
5838 * Tested channel joining (hence JOIN) in router environment
5839 successfully. Tested with two routers, two servers and two
5842 * Tested channel message sending in router environment successfully.
5844 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Added silc_server_save_channel_key into server.[ch] to save the
5847 received channel key in Channel Key payload processing. It is
5848 also used in JOIN command reply handling.
5850 Equivalent function silc_client_save_channel_key added into
5851 client.[ch] into client library.
5853 * Changed JOIN command reply to send information whether the channel
5854 was created or not (is existing already) and the channel key
5855 payload. Changed protocol specs accordingly.
5857 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5858 the request was sent by ID and not by nickname. Crashed on
5861 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5864 now correctly save the received data.
5866 * silc_server_free_sock_user_data now notifies routers in the
5867 network about entities leaving the network.
5869 At the same time implemented functions silc_server_remove_id
5870 and silc_server_send_remove_id to receive and send REMOVE_ID
5871 packets. The packet is used to notify routers in the network
5872 about leaving entities. The ID removed will become invalid in
5875 * Added function silc_idlist_del_server into server. Removes and
5876 free's server entry from ID list.
5878 * silc_server_private_message function now checks, if we are router,
5879 that the destination ID really is valid ID, naturally.
5881 * In router when NEW_ID packet is received (for new client) the
5882 hash of the Client ID is saved in the ID Cache but the
5883 client->nickname is set to NULL, instead of putting the hash
5886 IDENTIFY command now also checks that client->nickname must be
5887 valid. If it is not if will request the data from the server who
5888 owns the client. Added new function
5889 silc_server_command_identify_check.
5891 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5892 to set the command to already allocated Command Payload.
5894 * Tested private message sending in router environment with two
5895 routers, two servers and two clients. Fixed minor bugs and now
5898 * Fixed segfault from client's NAMES command. Used to crash if
5901 * Forwarded packets must not be routed even if it is not destined
5902 to the receiver. Changed server code comply with this.
5904 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added `require_reverse_mapping' boolean value to ServerParams
5907 structure. If TRUE (not default) the server will require that
5908 the connecting host has fully qualified domain name.
5910 If the reverse mapping is not required and hostname could not be
5911 found the IP address is used as hostname.
5913 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Implemented version string checking to both client and server.
5916 The check is incomplete currently due to the abnormal version
5917 strings used in development version of SILC.
5919 * Changed all command functions in server to use the new
5922 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Changed char *data to unsigned char *data in ID Cache system to
5925 support binary data as ID Cache data. Changed code to support
5926 binary data in lib/silccore/idcache.c.
5928 * Renamed silc_server_packet_relay_command_reply to
5929 silc_server_command_reply as it is normal packet receiving
5930 function. Rewrote the function to accept command replys for
5931 servers and not only for clients.
5933 * Mark remote router always as registered server if we are connecting
5934 to it. Otherwise, commands sent by the router to us are ignored.
5936 * All ID List find routines now returns the ID Cache Entry pointer
5937 as well if requested.
5939 * WHOIS command works now in router environment, tested with two
5940 routers, two servers and two clients.
5942 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5943 in router environment (as it is almost equivalent to WHOIS) but
5944 hasn't been tested thoroughly. Added new functions:
5946 silc_server_command_identify_parse
5947 silc_server_command_identify_send_reply
5948 silc_server_command_identify_from_client
5949 silc_server_command_identify_from_server
5951 * Disabled route cache adding because adding two different ID's with
5952 same IP replaces the old cache entry thus giving wrong route.
5953 The entry->router->connection is always the fastest route anyway
5954 so route cache may not be needed. Of course, new routes maybe
5955 established after receiving the ID when the entry->router->connection
5956 might not be anymore the most optimal.
5958 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Add route cache for received ID for fast routing.
5962 * Added silc_server_packet_route to route received packet on router
5963 that is not destined to us.
5965 * Renamed silc_server_get_route to silc_server_route_get.
5967 * Added id_string and id_string_len fields into SilcServer to
5968 include encoded ServerID for fast comparing without excess
5969 encoding of the ID's.
5971 * Cleaned up WHOIS command on server side. Added following static
5974 silc_server_command_whois_parse
5975 silc_server_command_whois_check
5976 silc_server_command_whois_send_reply
5977 silc_server_command_whois_from_client
5978 silc_server_command_whois_from_server
5980 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5981 arguments in command replies. All command functions should be
5982 updated to use this macro.
5984 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5986 * Minor typo fixes on command reply handling on server.
5988 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added silc_server_command_add_to_channel internal routine to add
5991 the client to the channel after router has created the channel and
5992 sent command reply to the server.
5994 * Added generic silc_server_send_command to send any command from
5997 * Use static buffer with ID rendering instead of duplicating data.
5999 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Fixed a channel user mode bug when joining to a channel server gave
6002 everybody channel founder rights, oops.
6004 * We mark ourselves as the router of the incoming server connection
6005 if we are router ourselves. This way we can check in some packet
6006 sending functions whether it is locally connected server. For
6007 incoming router connections we put NULL.
6009 * For router sending packets locally means now always sending the
6010 packet cell wide; to local clients and local servers. For normal
6011 server sending packet locally means sending it to only local
6014 * Fixed the JOIN command to really work in router environment. If the
6015 channel is created it is always created by the router. Router is
6016 also responsible of making the initial joining to the channel,
6017 sending JOIN notify to the sending server and distributing
6018 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6019 does not exist server doesn't do anything else but forward the
6020 command to the router which performs everything.
6022 * Added silc_server_send_channel_key function to send the Channel Key
6025 * Added silc_server_create_channel_key to create new channel key. The
6026 channel key is now re-generated everytime someone joins or leaves
6027 a channel, as protocol dictates. Note: channel->key_len is the
6030 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6033 packet_receive.[ch] to separate packet sending and receiving
6034 routines. The server.[ch] now includes everything else including
6035 actual packet processing (writing and reading data) and other
6038 Renamed silc_server_private_message_send_internal to
6039 silc_server_send_private_message. The routine is still though
6040 used only to relay private messages as server does not send
6041 private messages itself.
6043 Renamed silc_server_new_channel to silc_server_create_new_channel
6044 and added new function sicl_server_new_channel that handles the
6045 incoming New Channel packet. Added also new sending function
6046 silc_server_send_new_channel to send New Channel Payload.
6048 * Added new function silc_server_notify to process incoming notify
6049 packet to the server/router. Server may then relay the notify
6050 to clients if needed.
6052 * Added new function silc_server_new_channel_user to process incoming
6053 New Channel User packet. Router will redistribute the packet and
6054 send JOIN notify to its local clients and locally connected servers
6055 if needed. Normal server will send JOIN notify to its local client
6056 on same channel when received this packet. Added also corresponding
6057 sending function silc_server_send_new_channel_user to sent the
6060 * Added boolean route argument to send_notif_to_channel and
6061 packet_send_to_channel functions to attempt to route the packet
6062 if it is TRUE and send only locally if it is FALSE.
6064 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * silc_server_replace_id now broadcasts the received replace ID
6067 packet if it is not broadcast packet already. The router must
6068 broadcast to inform other routers about changed ID.
6070 * Added backpointer to server's router into SilcServer context in
6071 silcd/server_internal.h.
6073 * Fixed silc_server_packet_broadcast to send correct broadcast
6076 * The channel key is now distributed to the local client as soon
6077 as it is received from the router (in router environment) so that
6078 no other packet may be sent for the channel until client has
6081 * silc_server_remove_channel_user now broadcasts the received
6082 Remove Channel User packet if it is not broadcast packet already.
6083 The router must broadcast to inform other routers about removed
6086 * Added users field into SilcPacketContext that is a reference count
6087 of the context. One can increase the reference count by calling
6088 silc_packet_context_dup which is now changed to just increase the
6089 reference count instead of duplicating the data. The reference
6090 count is decresed by calling silc_packet_context_free that will
6091 free the data after the reference count hits zero.
6093 For now on the packet context and everything allocated into it
6094 (including the raw packet from network) must be freed by calling
6095 the new silc_packet_context_free function. Added also new function
6096 silc_packet_context_alloc that must be used now to allocate the
6097 context. This also means that if a routine is asynchronous from
6098 silc_[client/server]_packet_parse_type the packet context must
6099 be duplicated by calling silc_packet_context_dup. Otherwise it
6100 gets free'd after silc_[client/server]_packet_parse_type returns.
6101 Also, one must remember that if packet is duplicated then its
6102 reference count must be decresed by calling the free function as
6103 many times as it was duplicated.
6105 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6106 from both client and server.
6108 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Made joining to a channel working in router environment.
6112 * Cleaned up JOIN command on server side and create function
6113 silc_server_command_join_channel internal routine to make the
6116 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Changed silc_command_pending list to SilcDList. Also, added
6119 `ident' field to SilcServerCommandPending structure to identify
6120 the reply and to call correct callback.
6122 Added silc_server_command_pending_check function to replace the
6123 corresnponding macro. The silc_command_pending list is not
6126 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6127 to set identifier to previously allocated Command Payload. It
6128 is used to set identifier for command when resending Command
6131 * Added silc_command_payload_encode_payload to encode Command
6132 Payload buffer from SilcCommandPayload structure.
6134 * Added silc_argument_payload_encode_payload to encode Argument
6135 payload buffer from SilcArgumentPayload structure.
6137 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Changed WHOIS command to support router connection on server side.
6140 The whois request is always sent to router unless the server is
6141 standalone server. After server has received the reply from the
6142 router will it send the reply to the client.
6144 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6145 broadcast received broadcast packet. The function is used only
6146 by router. The broadcast packet is always sent to the router's
6149 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6150 render given ID to printable string, for log files for example.
6152 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * Made basic router to router connections working. At least they
6155 can now connect to each other but nothing really works the way
6156 they are supposed - yet.
6158 * Added new initiator token to RouterConnection configuration
6159 file in silcd/serverconfig.[ch]. It is used to tell whether we
6160 are the initiator to the remote router or whether we'll expect
6161 the other end to connect.
6163 * Moved registering of listener task to silc_server_init, hence
6164 the server starts listenning as soon as it is run, even if it
6165 does not have connections to other routers. Let's see how well
6168 * Changed default connection retry timeouts for more suitable in
6171 * Removed cipher and such arguments from silc_idlist_add_client
6172 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6173 Added new function silc_idlist_add_data to add the keys and stuff
6176 * Added SilcIDListData structure and added it to SilcClientEntry
6177 and SilcServerEntry as their first field in the structure. This
6178 way we can explicitly cast the ID entries to the SilcIDListData
6179 structure and get common data for the entries. In past, we had
6180 to first check what type of connection it is and then cast it to
6181 correct ID entry type. Now, we can directly cast the opaque
6182 pointer to the SilcIDListData (no matter what ID entry it actually
6183 is) and get the data needed.
6185 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6188 in some circumstances even if threre were timeout tasks, though not
6189 IO tasks, but tasks anyway. Now fixed.
6191 * Defined SilcServerConnection structure to hold connection specific
6192 stuff about directly connected servers and routers. The definition
6193 is currently in silcd/server_internal.h. I thought about having
6194 a bit more important role fro this struct but for now it is used
6195 only when connecting to other server (or router actually).
6197 * Added connecting retry support in server when connecting to
6198 router(s). The retry feature implement exponential backoff
6199 algorithm. Also, added SilcServerParams structure to hold default
6200 parameters for server. For now, it include these retry settings
6201 and are hard coded. After server is moded to be as Silc Server
6202 Library this structure will be more important.
6204 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Changed client librarys channel->clients table to SilcList and
6207 changed code accordingly.
6209 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6211 * Changed client's channel table to SilcList and changed code
6212 accordingly. Also changed SilcChannelClientEntry to include back-
6213 pointer to the channel so that client entry can use that structure
6214 as list as well and we have fast cross-reference to the channel.
6215 This change dramatically decreased the complexity of channel
6216 handling with client entry and vice versa (removed one extra
6217 loop when searching for channel entry from many functions).
6219 * Changed server->sim from table to SilcDList and changed code
6222 * NAMES command can now be used from user interface. It will show
6223 the user list on the channel, neatly.
6225 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6226 Code now saves realname of the user if it becomes available.
6228 * Renamed configure.in to configure.in.pre and made ./prepare
6229 script to automatically add correct version string to
6230 configure.in which it creates from configure.in.pre.
6232 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * NAMES command reply now shows users mode with the nickname when
6237 * Moved silc_client_ch[u]mode[_char] functions from
6238 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6239 place sucks, they are utility functions and should be in some
6242 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6244 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6247 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Added TRQ (efficient deque and list library) into lib/trq. This is
6252 a very good list library that is currently used in the SILC. Defined
6253 SilcList API over the library because I didn't like the API very
6254 much. See lib/trq/silclist.h for the API and examples of how to
6255 use the API. Fixed various places in the code to use the new
6256 SilcList API. The SilcList is meant for lists that has a structure
6257 already defined as a list. It is not suitable to add just some
6258 context to the list (in TRQ, the context is the list actually).
6260 So, I defined SilcDList that can be used for the purpose where
6261 predefined list structure does not exit. This can be used as
6262 such list. Now some context just can be added to the SilcDList.
6263 Currently this list is not used in the SILC just yet, though there
6264 are a lot places where this can replace dynamically allocated
6265 tables and I will fix these places, later, to use SilcDList.
6266 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6267 and use TRQ internally).
6269 Also fixed some annoying warning messages that the original TRQ
6270 code generated. Also minor changes to TRQ's Makefile.in.
6272 * Added support for querying by Client ID to both WHOIS and
6273 IDENTIFY commands into server, as required by the protocol.
6275 * Removed method function pointers from SilcBuffer structure. They
6276 weren't used to anything and just increased the context size for
6277 no good reason. This change also made silc_buffer_alloc and
6278 silc_buffer_free functions inline functions.
6280 * Disabled command flooding detection support until it's fixed so
6281 that it accepts commands in but does not execute them more than once
6284 * Added silc_net_localhost(), to return local hostname, into
6285 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6286 that must be initialized before calling silc_client_init.
6288 * Added new function: silc_server_send_notify_on_channels to send
6289 notify messages to all channels client has joined. It is assured
6290 that the message is sent only once per client.
6292 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6293 lib/silcutil/silcutil.[ch] as silc_format function. The new
6294 function is generic and is used by server as well, not only by
6295 the logging routines.
6297 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6298 the provided version string was not acceptable. Added new function:
6299 silc_ske_check_version into lib/silcske/silcske.h. The function
6300 must be implemented by the application (client or server) and it
6301 does not reside in the SKE library. The function checks the version
6302 string remote end sent.
6304 * Added back pointers (to opaque context and to SilcSocketConnection)
6305 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6307 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6308 duplicate packet context structure.
6310 * Changed `notify' client operation to send same arguments as client
6311 receives from server except for ID's. ID's are mapped to correct
6312 ID entry and that is returned. Also, if channel entry is not sent
6313 by server but the notify is for channel the channel entry is sent
6314 to application (otherwise application doesn't know that it is for
6315 channel (library gets it from packet's Destination ID)).
6317 * Added silc_client_remove_from_channels into client library to
6318 remove a client from all channels it has joined to. Used when
6319 received SIGNOFF notify from server. Added also new function
6320 silc_client_replace_from_channels to replace old ID entry with
6321 new ID entry on all channels. Used when received NICK_CHANGE
6324 * Fixed ID Cache list handling in silc_idlist_get_client in
6325 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6326 to get (or query) client by ID.
6328 * Updated TODO list.
6330 * Added connection authentication status message defined by the
6331 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6332 support for these into the code in client and server side.
6334 * Added generic function silc_client_send_command to send any command
6335 with variable argument list. Application should use this function
6336 to send commands if the command functions provided by the library
6337 does not suite for the application's user interface needs.
6339 * Added new `failure' client operation. Application is notified about
6340 received failure packet if client is executing a protocol. In this
6341 case the protocol's execution has failed.
6343 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6344 is required by the protocol.
6346 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6347 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6350 * Added status flag to SilcSKE object to indicate realtime status
6351 of the SKE protocol.
6353 * Application receives now exactly same command reply arguments as
6354 the library receives from server. However, if ID is received the
6355 corresponding ID entry is returned to the application (eg. Client
6356 ID is mapped to correct SilcClientEntry entry and that is returned).
6357 Changed command_reply client operation due to this change.
6359 * Changed all ID's in commands and in command replys as ID Payloads.
6360 Change affected both client and server side codes.
6362 All ID's sent in SILC network (with execption of ID's in SILC
6363 Packet header) are sent in ID Payload to support variable length
6366 * Server now notifies nick changes and notifies all clients on
6367 the channels about the new nickname (about the new Client ID,
6370 * Implemented CMODE command to change channel modes. Supports all
6371 channel modes defined by the protocol specs except ban and invite
6372 lists. (Also, private channel key mode is supported but support for
6373 setting private channel key in client is missing, thus, this mode
6374 has no effect on client side (except that server requires that the
6375 client uses private channel key and normal channel traffic does not
6378 Also, invite mode works per se, but INVITE command does not work
6379 yet correctly, so you can set channel as invite only channel but
6380 inviting clients to the channel does not work (it is yet to be
6381 thought what's the best way to do it).
6383 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6384 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6385 Implemented CUMODE command to change user's mode on the channel.
6386 Supports all modes defined by the protocol specs.
6388 * Added NAMES command reply to return users modes on the channel.
6390 * Removed unnecessary and slow ciphers from lib/silccrypt.
6392 * Set SO_KEEPALIVE option to connection sockets by default.
6394 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6396 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6397 redefined the Notify Payload into protocol specs.
6399 * Added silc_id_payload_parse_id to get ID directly from raw
6402 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6405 accept searching by Client ID as well.
6407 * Added support for LEAVE and SIGNOFF notify types in client library.
6409 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6410 to parse ID Payload from raw data.
6412 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Added flags parameter into silc_ske_assemble_security_properties
6415 function in lib/silcske/silcske.[ch].
6417 * Changed notify client operation to fit better for notify messages
6418 sent by server. The notify payload received from server is now
6419 passed to the application (after parsing it to SilcNotifyPayload).
6420 It is application's responsibility to retrieve the arguments
6421 from the payload and show the message the way it wants. The message
6422 sent by server is implementation specific.
6424 * Changed public keys to comply with the protocol specification.
6425 Old public keys are not supported anymore and are not compatible.
6427 * Removed nickname from Channel Payload as the latest draft removed
6428 it. The client must resolve the nickname from the NAMES command
6429 reply received when it joined the channel.
6431 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6433 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Fixed some errors in protocol specification drafts.
6437 * Created lib/silccore/silcnotify.c to implement Notify Payload
6438 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6439 generic payloads described by protocol specifications. The file
6440 includes implementations for ID Payload and Argument Payload.
6442 * Changed Command Payload implementation to use the new Argument
6443 Payload. Changed command_xxxx_payload to command_payload_xxxx
6444 to comply with SILC coding conventions.
6446 * Added suppport for Argument Payload handling in Notify Payload
6447 implementation as protocol requires it. Added the new support
6448 into server and client lib as well.
6450 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added support for multiple nicknames on same channel. [n] is
6453 added locally to the nickname if there are more than one same
6454 nicknames on the channel.
6456 * Server now sends all nicknames that matched WHOIS request.
6457 Client also shows the list received from server.
6459 * Added TOPIC command to client side. User can now set and show
6460 current topic on channel.
6462 * Added MOTD command to client and server. Also, server sends the
6463 motd when client connects to the server.
6465 * Changed version strings to comply ISO 8601.
6467 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Fixed protocol error handling in client library. It should now
6470 cope even if the SKE fails for some reason.
6472 * Made new protocol specification drafts for submitting to IETF.
6474 * Implemented TOPIC command to server in silcd/command.c.
6476 * Added two new notify types into lib/silccore/silcnotify.h:
6477 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6478 notify nickname change and topic setting/change on a channel.
6480 * API change of command_reply operation in client library. The
6481 application gets now the status type received from server as well.
6483 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6487 * Cras fixed and optimized the packet handling even further and
6488 it should work now. Minor change to the prototype of function
6489 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6491 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Added new function into lib/silcutil/silcschedule.[ch]:
6494 silc_schedule_with_fd to select() a specified fd. The function
6495 returns after timeout expires or data arrives or goes. The
6496 function is used by packet routines to wait that all data is
6497 received from network.
6499 * Fixed data reading from network in lib/silccore/silcpacket.c.
6500 The code now assures that all data is read from the fd and then
6501 continues packet processing. This was a bug fix since the code
6502 used to drop some data in some circumstances.
6504 * Added new function into lib/silcclient/client.[ch]:
6505 silc_client_start_key_exchange to start key exchange after
6506 connection has been established to server. The code internally
6507 now uses this funtion but its main purpose was to provide it
6508 for applications that perform their own connecting. After
6509 application has created a connection it merely calls this
6510 function to start the key exchange between client and server.
6511 The library takes care of everything else after that.
6513 Updated also lib/silcclient/README to explain the usage of
6516 * Do not send to application information that connection has
6517 been established. Application gets notified it by connect
6520 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Applied cras's patch to add silc_schedule_one function. The
6523 function runs scheduler once and returns.
6525 * Fixed the scheduler after cras messed it up. The timeout
6526 handling works now as it's supposed to work.
6528 * Added into lib/silccore/ silcnotify.h to include notify
6529 message types support. Changed silc_server_send_notify*
6530 functions, in server.[ch], to support those new notify types.
6531 Added the support for the notify types into client library,
6532 as well. Added new notify client operation into ops.h in
6535 * Changed silc_server_packet_send_to_channel to send normal
6536 packets instead of just channel message packets. The function
6537 is now used to send the notify packets to channels. It is not
6538 used to send channel message packets anymore, as server never
6541 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6542 va_arg()s as it seems to require it nowadays. I guess, if SILC
6543 is compiled with older va_arg() the new code should work anyway.
6545 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Splitted core library. Core library (lib/silccore) includes
6548 now only SILC protocol specific core (and common) components.
6549 Created new utility library (lib/silcutil) that includes more
6550 generic purpose stuff. The stuff for util library was taken
6551 from the old core library. This was minor and easy split.
6553 * Created SILC Client Library (lib/silcclient) that includes
6554 implementation of the SILC client without user interface. This
6555 was major move from silc/ directory. The code has been changed
6556 so that it is transparent towards the user interface. The
6557 silc/ directory includes now the same user interface as before
6558 and it uses the new client library. Read lib/silcclient/README.
6559 Basicly, the client library performs everything else related
6560 to SILC except user interface handling. Also, configuration
6561 files are considered to be part of user interface and library
6562 does not handle them.
6564 This change also changed a lot of structures, function naming etc.
6565 Most important change was that SilcClientWindow object was
6566 renamed to SilcClientConnection in the client library. Created
6567 also new file lib/silcclient/ops.h. Also added new files
6568 silc/local_command.[ch] and silc/client_ops.[ch].
6570 All these changes were made to make it easier for user interface
6571 designers to create what ever user interface for the SILC client
6574 It is also expected that the server will be moved to lib
6575 directory as well and SILC Server Library will be created;
6576 sometimes in the future.
6578 * Removed Local commands from lib/silccore/silccommand.h as
6579 they are application specific and new client library does not
6580 handle any of those anymore.
6582 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6583 old client implementation in silc/.
6585 * Added support for callback functions in SILC_LOG_* macros.
6586 Application can now set its own callbacks that will be called
6587 instead of using the default functions that will always print
6588 the debug messages to stderr (or stdout). Also, debugging can
6589 now be disabled by setting silc_debug to FALSE and re-enabled by
6590 setting it to TRUE. Note, that logging will still work even
6591 if debugging is disabled.
6593 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6594 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6595 silc_log_reset_debug_callbacks.
6597 * To enable debugging in silc client one must give now -d
6598 option on command line.
6600 * Changed silc_schedule_init to automatically allocate task queues
6601 if they are not allocated before calling it.
6603 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6605 * Added GMP 3.1 into math library.
6607 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6610 a channel in SILC network. The packet is used by servers and
6611 routers to notify other routers that user has left a channel.
6612 This little feature was missing until now. Added the feature
6613 to protocol specification as well.
6615 Added functions: silc_server_send_remove_channel_user and
6616 silc_server_remove_channel_user into server.[ch].
6618 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6619 lib/silccore/silcpacket.h. However, they are not implemented
6622 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Fixed joining to a channel and sending channel messages
6625 between server and router. The channel message sending should
6626 now work inside a cell.
6628 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Fixed the private message sending between server and router.
6631 The private message sending should now work inside a cell.
6633 * Added silc_server_replace_id into server.[ch] to replace
6634 existing ID in the SILC network.
6636 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6637 and silc_idlist_replace_server_id into idlist.[ch] in server.
6639 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6641 * Fixed the server to server connections. Server can again now
6642 connect to router. Router to router connections probably does
6645 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6647 * Added dynamic protocol registering support. Now protocols can
6648 registered and unregistered on the fly. Patch by cras.
6650 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Added lib/contrib directory to hold routines that some platforms
6653 don't have but are needed by SILC.
6655 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6656 into lin/contrib to provide getopt() and getopt_long() for
6657 those who don't have it.
6659 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Added AWAY command to client. When away message is set and
6662 client receives a private message packet the client automatically
6663 replies to the sender with the away message.
6665 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6666 bug seemed to be the cause of recent problems when compiling
6669 * Added version detection support to SKE protocol specification
6670 and added the new changes to the SKE implementation as well.
6671 There were other minor changes in the SKE protocol as well.
6673 Many changes in lib/silcske/silcske.[ch] and in
6674 lib/silcske/payload.[ch].
6676 * Added ^U functionality, clear input line. Patch from cras.
6678 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Mainly small bugfixes on core library. Fixed some debugging
6681 logging and buffer overflow in silclog.c.
6683 * Updated config.sub and config.guess on the distribution tree.
6685 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Added command lagging support in server. Client may execute
6688 commands now only once in two seconds.
6690 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Optimized packet reception. MAC computation and checking is now
6693 also more optimized. A lot previously duplicated code is now
6694 used as generic by both client and server.
6696 * Fixed key pair generation in clientutil.c
6698 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6700 * Added into lib/silccore/silcbufutil.[ch] new function;
6701 silc_buffer_realloc.
6703 * Moved generic packet sending/encryption functions to
6704 lib/silccore/silcpacket.[ch] from client and server. Some
6705 rewriting of the functions.
6707 * Moved all generic packet reception/decryption functions to
6708 lib/silccore/silcpacket.[ch] from client and server. The
6709 packet processing is now much cleaner in both client and server.
6710 These were major changes in both client and server.
6712 * Created many common functions in server to do packet sending.
6713 Previously code were duplicated a lot, this has been removed
6716 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Rewrote major parts of the ID cache system. Don't know
6719 whether it is better now or not but at least the API is more
6722 * Major rewrite on ID cache stuff on client because of the ID
6723 cache API changes. Added idlist.c to client.
6725 * Also major rewrite on ID cache stuff on server as well.
6726 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6727 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6728 in hand, instead they are all put into the ID cache system now.
6729 All server_idlist_* routines uses ID cache now instead of
6730 traversing its own lists (those lists does not exist anymore).
6731 SilcIDList though still exists. Also, SilcXXXEntry's are
6734 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Finally made the SKE implementation compliant to the protocol
6737 specification. All mp integers are now binary encoded as
6738 opposed being HEX encoded.
6740 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6743 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6744 functions: silc_[encode/decode]_pem. Also added function
6745 silc_encode_pem_file to PEM encode with newlines ('\n') for
6748 * SILC public keys are now encoded either PEM or binary. Same
6749 option is for private keys as well. By default private keys
6750 are binary encoded and public keys PEM encoded. Silly HEX
6751 encoding were removed.
6753 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6754 function to create fingerprints.
6756 * Fixed a bug in SHA1; does not change the original data anymore.
6758 * Partly implemented INFO command on client and server side.
6759 Fixed CLEAR command. Changes to SERVER command; show current
6760 server(s) when giving command without arguments. Added
6761 VERSION command to client.
6763 * Added check to server that unregistered connections cannot
6764 execute commands (unless it is specificly allowed).
6766 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Fixed screen refresh.
6770 * Fixed channel joining bug from client. On some circumstances
6771 client tried to join to a channel it had already joined.
6773 * Added public key verification process into client's protocol.c.
6774 The client now verifies the public key from user and saves
6775 it into ~./silc/serverkeys/ directory.
6777 Added into: clientutil.[ch]: silc_client_verify_server_key.
6779 * Changed SKE protocol's silc_ske_initiator_finish function
6780 to accept callback function that verifies the received public
6781 key. Removed old silc_ske_verify_public_key function.
6783 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6786 silc_pkcs_private_key[_data]_set.
6788 * Made the password and public authentication more cleaner in
6789 server's protocol.c.
6791 * Removed historic and obsolete protocol `channel_auth' from
6792 both client and server.
6794 * Removed wrong way of sending command status messages from
6795 server to client in server's command.c. The old way violated
6796 protocol specification.
6798 Changes to silccore/silccommand.[ch]: removed
6799 silc_command_encode_status_payload -> not needed anymore,
6800 changed silc_command_encode_payload_va to accept extra
6801 argument on variable argument list. The argument type must
6802 now be provided to the function. Also, added new function:
6803 silc_command_encode_reply_payload_va which is same as
6804 normal command_encode_payload_va except command status type
6805 is provided as extra argument.
6807 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Added ~./silc directory handling. The directory includes the
6810 public and private keys for the client.
6812 Added silc_client_check_silc_dir, silc_client_create_identifier
6813 and silc_client_load_keys.
6815 * Implemented SILC protocol compliant public key. Added public
6816 and private key saving to and loading from files.
6818 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6819 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6820 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6821 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6822 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6824 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6825 silc_pkcs_load_[public/private]_key.
6827 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6829 * Added silc_server_get_route (route.[ch]) to get connection
6830 data for the fastest route for given ID.
6832 * Implemented INVITE command on client and server. The command
6833 were re-defined in the SILC Protocol Specification and the
6834 implementation now complies with the specification.
6836 * Implemented PING command on client and server.
6838 * Implemented NAMES command on client and server. The server side
6839 supports currently only normal server not router server yet.
6840 Some changes to NAMES definition in SILC protocol specification.
6842 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Implemented LEAVE command on client and server.
6846 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6847 again. This change was made to the protocol as well. Server
6848 should not violate the protocol specification anymore.
6850 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6853 was tested. SOCKS4 was not but should work anyway.
