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

572 file is silcd/serverid.c.
574 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
576 * Added silc_net_gethostby[addr/name] into the
577 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
578 routines. Added silc_net_is_ip[4/6]. Affected file is
579 lib/silcutil/unix/silcunixnet.c. All routines that take
580 address as argument now supports both IPv4 and IPv6 addresses.
582 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
584 * Fixed LIST command reply sending in server. Affected file
587 * Server now sends the kicker's client ID in the KICK notify
588 to the kicked client. Affected file silcd/command.c.
590 * The client library now parses the kickers client ID and
591 UI displays it. Affected files lib/silcclient/client_notify.c
592 and irssi/src/silc/core/silc-channels.c, module-formats.c.
594 * Made all payload parsing function prototypes consistent.
595 They all take now const unsigned char * and uint32 pair as
596 the payload data instead of SilcBuffer. Changes all around
597 the source tree. Other unsigned char* -> const unsigned char*
598 changes around the tree as well.
600 * Optimized SFTP client and server packet sending not to
601 allocate new buffer for each packet but to recycle the
602 first allocated buffer. Affected files are
603 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
605 * Optimized the SFTP client to use SilcList instead of
606 SilcDList for requests, because it is faster. Affected file
607 is lib/silcsftp/sftp_client.c.
609 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
610 into lib/silccore/silcid.[ch].
612 Renamed silcpayload.[ch] into silcargument.[ch].
614 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
616 * If client entry is deleted with active key agreement
617 session, abort the session.
619 The silc_client_abort_key_agreement now calls the completion
620 callback with new SILC_KEY_AGREEMENT_ABORTED status.
622 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
625 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
627 * Don't use __restrict in older GCC's. Affected file is
628 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
630 * silc_net_localhost now attempts to reverse lookup the
631 IP/hostname. Affected file lib/silcutil/silcnet.c.
633 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
634 command. It can be used to gain founder privileges at
635 the same time when joining the channel.
637 Defined that the SILC_NOTIFY_TYPE_KICKED send the
638 kicker's client ID as well. Updated protocol specs.
640 Defined that the server must send SILC_COMMAND_IDENTIFY
641 command reply with error status to client who sent
642 private message with invalid client ID.
644 Updated the protocol specification.
646 * Added silc_server_send_command_reply to send any
647 command reply. Affected file silcd/packet_send.[ch].
649 * Added silc_id_payload_encode_data to encode ID payload
650 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
652 * The server now send IDENTIFY command reply with error
653 status if client ID in private message is invalid. Affected
654 file silcd/packet_receive.c.
656 * Save the server key file with server's IP address in
657 the filename instead of hostname. The affected file is
658 irssi/src/silc/core/client_ops.c.
660 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
665 * Added libtool support for compiling shared objects in
666 lib/silcsim. Affected file configure.in.pre and
667 lib/silcsim/Makefile.am. Original patch by cras.
669 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
671 * Pid file configuration, and server's config file fixes
672 patch by toma. Updated CREDITS file.
674 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
676 * Fixed silc_client_channel_message to not try to decrypt
677 the message twice if it resolved the destination client
678 information. This could cause of dropping one channel
679 message. Affected file lib/silcclient/client_channel.c.
681 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
683 * Added silc_client_run_one into lib/silcclient/silcapi.h and
684 lib/silcclient/client.c. This function is used when the SILC
685 Client is run under some other scheduler, or event loop or
686 main loop. On GUI applications, for example this may be
687 desired to used to run the client under the GUI application's
688 main loop. Typically the GUI application would register an
689 idle task that calls this function multiple times in a second
690 to quickly process the SILC specific data.
692 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
694 * Fixed silc_server_drop() for dropping the supplementary
695 groups as well, this could cause a security hole on some
698 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
700 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

704 to run server on foreground. A patch by debolaz.
705 Affected files silcd/server.c, silcd/silcd.c.
707 * Fixed MOTD to return the MOTD file server name. Affected
708 file silcd/command.c.
710 * Added INFO command reply handling to the Irssi SILC Client.
711 Affected file irssi/src/silc/core/client_ops.c.
713 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
715 * Fixed the silc_idcache_list_* routines to really support
716 the dynamic list. Fixes a crash. Affected file is
717 lib/silccore/silcidcache.c.
719 * Fixed the LIST command reply to really call LIST command's
720 pending callbacks. Affected file silcd/command_reply.c.
722 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
724 * Update conn->local_entry->nickname after giving NICK
725 command. Affected file lib/silcclient/command.c.
727 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
729 * Added the [pid] option to the silcd configuration file
731 Affected files: serverconfig.[ch] and silcd.c
733 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Save fingerprint in WHOIS command reply in server.
736 Affected file silcd/command_reply.c.
738 * Fixed NICK commands pending callback registration.
739 Affected file lib/silcclient/command.c.
741 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Use ++server->cmd_ident when sending commands in server,
744 instead of random number. Affected file silcd/command.c.
746 * Fixed GETKEY command reply to call actually GETKEY pending
747 command callbacks. Affected file silcd/command_reply.c.
749 * A bit stricter check for nicknames. Check for same nickname
750 in NICK command also. Affected file silcd/command.c.
752 * Do not call INFO command everytime client ID changes, only
753 during first connecting. Affected file lib/silcclient/client.c.
755 * Set the new nickname only after successful command reply for
756 NICK command is returned by server. Affected file
757 lib/silcclient/command.c.
759 * Remove nicknames from nicklist during server_signoff notify.
760 Should fix /NAMES bit more. The affected file is
761 irssi/src/silc/core/silc-channels.c.
763 * Added `fingerprint' field to the SilcIDListData in the
764 silcd/idlist.h to hold the fingerprint of the client's
767 Send the fingerprint of the client's public key in WHOIS
770 Affected files silcd/command.c, and silcd/idlist.[ch].
772 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
773 create fingerprint from given data.
775 * Show the fingerprint of the client's public key in WHOIS.
776 Affected files irssi/src/module-formats.[ch] and
777 irssi/src/silc/core/client_ops.c.
779 * Format the multiple same nicknames also during JOIN and
780 NICK_CHANGE notifys. Affected file is
781 lib/silcclient/client_notify.c.
783 * Do not print error on screen for invalid private message
784 payload since it can come if someone is sending private
785 messages with wrong key. Affected file
786 lib/silccore/silcprivate.c.
788 * Fixed multiple concurrent /PING crash. Affected file
789 lib/silcclient/command.c.
791 * Changed the wrong ID encoding. All IP addresses must be
792 in MSB first order in encoded format. They were encoded
793 wrong and was in LSB format. Affected files are
794 silcd/serverid.c, lib/silcutil/silcutil.c.
796 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
798 * Call the `connect' client operation through the scheduler
799 in case of error. Affected file lib/silcclient/client.c.
801 * Call the `failure' client operation even if the error
802 occurred locally during a protocol. Affected file is
803 lib/silcclient/protocol.c.
805 * Added support of sending LIST command to router from normal
806 server. This way normal server can get list of all channels
807 in the network too. Fixed the channel list sending in the
808 server too. Affected files are silcd/command.c, and
809 silcd/command_reply.[ch].
811 * Added silc_server_update_channels_by_server and
812 silc_server_remove_channels_by_server. They are used during
813 disconnection of primary router and in backup router protocol.
814 Affected file silcd/server_util.[ch], silcd/server.c and
815 silcd/server_backup.c.
817 * Fixed channel adding to global list in IDENTIFY command
818 reply in server. Affected file silcd/command_reply.c.
820 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
822 * If the incoming packet type is REKEY or REKEY_DONE process
823 that packet always synchronously. Fixes yet another MAC
824 failed error on slow (dialup) connections. Affected file
825 lib/silcclient/client.c and silcd/server.c.
827 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
829 * Call check_version SKE callback for initiator too. Affected
830 file lib/silcske/silcske.c.
832 * Implemented fix for security hole found in the SKE that was
833 fixed in the specification few days back; the initiator's
834 public key is now added to the HASH value computation.
835 Added backwards support for the old way of doing it too, for
836 old clients and old servers. Affected file is
837 lib/silcske/silcske.c.
839 * Enabled mutual authentication by default in SKE. If initiator
840 is not providing mutual authentication the responder will
841 force it. This will provide the proof of posession of the
842 private key for responder. The affected files are
843 lib/silcclient/protocol.c and silcd/protocol.c.
845 * Do not cache anymore the server's public key during SKE.
846 We do mutual authentication so the proof of posession of
847 private key is done, and if the server is authenticated in
848 conn auth protocol with public key we must have the public
849 key already. Affected file silcd/protocol.c.
851 * Added new global debug variable: silc_debug_hexdump. If
852 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
853 file lib/silcutil/silclog.[ch].
855 * Fixed compilation warning due to char * -> const char *.
856 Affected files lib/silcutil/silcnet.h, and
857 lib/silccore/silcauth.[ch].
859 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
861 * Fixed CMODE command when new channel key was created. If
862 the creation failed the old key was removed. Next time giving
863 same command would crash the server since the old key was
864 freed already. Affected file silcd/command.c.
866 * Fixed the silc_server_announce_get_channels to not crash
867 on reconnect. Affected file silcd/server.c.
869 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Added silc_log_set_debug_string function to set a regex
872 string to match for debug output. Only the function names,
873 or filenames matching the given debug string is actually
874 printed. This way it is possible to filter out those debug
875 strings that user is not interested in.
877 Fixed a bug in silc_string_regexify.
879 Affected files lib/silcutil/silclog.[ch], and
880 lib/silcutil/unix/silcunixutil.c.
882 * Changed the -d options in both server and Irssi SILC client
883 to take the debug string as argument. Affected files
884 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
886 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
888 * Added silc_hash_babbleprint to create a Bubble Babble
889 Encoded fingerprint. The encoding is developed by Antti
890 Huima (draft-huima-babble-01.txt), and it creates human
891 readable strings out of binary data. Affected file
892 lib/silccrypt/silchash.[ch].
894 * Print the babble print now in addition of fingerprint as well
895 in Irssi SILC client. Affected files are
896 irssi/src/fe-common/silc/module-formats.[ch],
897 irssi/src/fe-common/silc/core/client_ops.c.
899 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Fixed a security problem found in SKE. The initiator's
902 public key too is now added to the HASH hash value creation
903 which is signed by the responder to create the SIGN value.
904 This will prevent anyone in the middle to lie to the responder
905 about the initiator's public key. If this is done now, the
906 man in the middle will get caught. Updated the protocol
909 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Better installation directory handling. Configure module
912 paths and other paths automatically to example_silc* files
913 in doc/. A patch by toma.
915 * Fixed compiler warning from MPI library, and from SILC RNG.
918 * Added SILC_SERVER_PID_FILE to define the pid file for server.
919 It can be configured with ./configure. A patch by toma.
921 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
923 * Find correct make to use in prepare-clean. A patch by
924 toma. Affected file prepare-clean.
926 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
928 * Added irssi variables use_auto_addr, auto_bind_ip,
929 auto_bind_port and auto_public_ip.
931 * Changed the interface for silc_client_send_key_agreement
932 in lib/silcclient/silcapi.h
936 irssi/src/silc/core/silc-core.c
938 lib/silcclient/silcapi.h
939 irssi/src/silc/core/silc-channels.c
940 lib/silcclient/client_keyagr.c
943 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Added silc_pkcs_public_key_compare to compare two
946 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
948 * Check that the client who set the founder mode on the
949 channel is the same client that is giving the founder
950 mode to itself. It is done by comparing the saved public
951 key (it is saved even in the authentication is passphrase).
952 Affected file silcd/command.c.
954 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Do not process packet for disconnected socket connection.
957 Affected file lib/silccore/silcpacket.c.
959 * Process the DISCONNECT packet through scheduler in the
960 client library. Affected file lib/silcclient/client.c.
962 * Fixed the silc_client_packet_parse to not to increase
963 the packet sequence number if the conn->sock and the
964 current socket connection is not same. This can happen
965 for example during key agreement when the conn includes
966 multiple socket connections (listeners). Affected file
967 lib/silcclient/client.c.
969 * The sender of the file transfer request now provides also
970 the pointer (listener) for the key exchange protocol. If
971 the listener cannot be created then it sends empty key
972 agreement and lets the receiver provide the listener.
974 Added `local_ip' and `local_port' arguments to the
975 silc_client_file_send. If they are provided they are used,
976 if not then it will attempt to find local IP address, if
977 not found or bind fails then the remote client will provide
980 Affected files are lib/silcclient/client_ftp.c and
981 lib/silcclient/silcapi.h.
983 * Extended the FILE SEND command to support defining the
984 local IP and port for key exchange listener. They are
985 optional. Affected file irssi/src/silc/core/silc-servers.c.
987 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Defined to WHOIS command reply the sending of fingerprint
990 of the client's public key (if the proof of posession of the
991 corresponding private key is verified by the server).
992 Updated to the protocol specification.
994 * Added support of receiving the client's public key's
995 fingerprint in command reply in client library. Affected
996 file is lib/silcclient/command_reply.c, and
997 lib/silcclient/idlist.[ch].
999 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Do not send over 128 chars long nickname to the server
1002 in NICK command. Affected file lib/silcclient/command.c.
1004 * Do not send over 256 chars long channel names to the server
1005 in JOIN command. Affected file lib/silcclient/command.c.
1007 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Assure that silc_server_close_connection cannot be called
1010 twice for same socket context. Affected file is
1013 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1015 * Send error message to application if opening file for
1016 writing during file transfer fails. Affected file is
1017 lib/silcclient/client_ftp.c.
1019 Remove all file transfer sessions for a client that we're
1020 removing from ID cache.
1022 Affected file is lib/silcclient/client_ftp.c.
1024 * Fixed silc_net_addr2bin to return correct address. Affected
1025 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1027 * Fixed file transfer session removing on signoff notify.
1028 Affected file irssi/src/silc/core/silc-servers.c.
1030 * Added the SilcClientFileError to be returned in the monitor
1031 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1032 Affected file lib/silcclient/silcapi.h.
1034 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Fixed a crash in silc_client_ftp_free_sessions and
1037 silc_client_ftp_session_free_client. Affected file
1038 lib/silcclient/client_ftp.c.
1040 * Added `disabled' field in the SilcChannelEntry in the server
1041 to indicate if the server entry is disabled. Affected file
1042 silcd/idlist.h, silcd/command[_reply].c.
1044 * SILC server adds now /var/run/silcd.pid everytime it is
1045 started. Affected file silcd/silcd.c.
1047 * Added silc_server_packet_send_clients to send a packet to
1048 the provided table of client entries. Affected file
1049 silcd/packet_send.[ch].
1051 * Fixed a crash in client resolving in client_prvmsg.c in
1052 client library. Affected file lib/silcclient/client_prvmsg.c.
1054 * Do not actually remove the client directly from ID cache
1055 during SERVER_SIGNOFF, but invalidate it. This way we
1056 preserve the WHOWAS info for the client. Affected file
1057 silcd/server_util.c.
1059 * Fixed SERVER_SIGNOFF notify handling in the server. The
1060 server is now able to process incoming SERVER_SIGNOFF notify
1061 for a server that it doesn't even know about. It will remove
1062 the clients provided in the notify. Affected file
1063 silcd/packet_receive.c.
1065 * Check for partial packet in data queue after every packet that
1066 was found from the queue. Return and wait for more data if
1067 there is partial data in queue. Affected file is
1068 lib/silccore/silcpacket.c.
1070 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1072 * Added SilcClietFileError enum to indicate error in
1073 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1074 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1075 Affected files lib/silcclient/silcapi.h and
1076 lib/silcclient/client_ftp.c.
1078 * Check that newsize in silc_buffer_realloc is larger than
1079 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1081 * Added better monitor of file transfers. It now monitors
1082 key agreement protocol during the file transfer too. Added
1083 error reporting too. Affected files
1084 irssi/src/silc/core/silc-servers.c,
1085 irssi/src/fe-common/silc/module-formats.[ch].
1087 * Wrote a help file for FILE command.
1089 * Added silc_rng_global_get_byte_fast to get not-so-secure
1090 random data as fast as possible. Random data is read from
1091 /dev/urandom if available and from the SILC RNG if not
1092 available. It is used in padding generation. Affected file
1093 lib/silccrypt/silcrng.[ch].
1095 * All packets in client library are now processed synchronously.
1096 Optimized packet processing a lot. Affected file
1097 lib/silcclient/client.c.
1099 * All server connection packets are processing synchronously
1100 now in server, to optimize packet processing. Affected file
1103 * Include files are installed now only in Toolkit distribution
1104 if make install is given. Affected files: all Makefile.am's.
1106 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Assure that silc_client_notify_by_server_resolve does not
1109 resolve the client information multiple times. If it cannot
1110 be found by the first it cannot be found at all. Affected
1111 file lib/silcclient/client_notify.c.
1113 * Fixed WHOWAS command reply calling. Affected file
1114 lib/silcclient/command_reply.c.
1116 * Removed all references to silc_idlist_get_client from the
1117 Irssi SILC client since that call is internal call used by
1118 the library. The Irssi SILC client will use now client
1119 retrieval functions found in silcapi.h.
1121 * Fixed a bug in resolving nickname info before sending
1122 private message. It used freed memory. Affected file
1123 irssi/src/silc/core/silc-servers.c.

1144 * Added silc_net_localip to return local host's IP address.
1145 Affected file lib/silcutil/silcnet.[ch].
1147 * If key exchange or rekey protocol is active for a connection
1148 parse all packets syncronously since there might be packets
1149 in packet queue that we are not able to process without first
1150 processing packets before them. Affected file silcd/server,
1151 lib/silcclient/client.c.
1153 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1154 whether library should continue processing the packet.
1155 Affected file lib/silccore/silcpacket.h.
1157 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1186 lib/silcutil/silcutil.[ch].
1188 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Resolve the client info when received private message or
1191 channel message for a client which nickname we don't know.
1192 Affected files lib/silcclient/client_prvmsg.c and
1193 lib/silcclient/client_channel.c.

1201 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1202 is incomplete and is being resolved, it won't be resolved
1205 Make sure also that USERS command reply does not resolve
1206 twice information. Affected file is
1207 lib/silcclient/command_reply.c.
1209 Make sure that silc_client_get_clients_by_list does not
1210 resolve twice same information.
1212 * Check for valid client->id in the silc_server_free_client_data.
1213 Affected file silcd/server.c.
1215 * Fixed /GETKEY nick@server not to crash if the server entry
1216 is not found. Affected file lib/silcclient/command.c.
1218 * Fixed the silc_server_check_cmode_rights to check the
1219 requested modes correctly. Affected file silcd/command.c.
1221 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1223 * Better checks for non-printable chars in nick added.
1224 Affected file silcd/command.c.
1226 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Call the silc_server_udpate_servers_by_server in the
1229 primary router that comes back online in the backup resuming
1230 protocol. Otherwise it routes packets wrong. Affected file
1231 silcd/server_util.[ch], silcd/server_backup.c.
1233 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1236 lib/silcutil/silcbuffmt.[ch].
1238 * Redefined the SILC packet header to include the padding
1239 length. Affected file lib/silccore/silcpacket.[ch].
1241 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1242 length for maximum padding up to 128 bytes). Affected
1243 file lib/silccore/silcpacket.h.
1245 * Removed all backwards support for old 0.5.x MAC thingies.
1246 The SILC packet header change makes it impossible to be
1247 backwards compatible.
1249 * Send the ENDING packet with timeout in the backup resuming
1250 protocol. This is to assure that all routers has connected
1251 to the primary router. Affected file silcd/server_backup.c.
1253 * Changed the RNG to take the first IV from random data. It
1254 used to take it from zero actually. Changed the RNG also
1255 to use /dev/urandom during session. /dev/random is used
1256 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1258 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Changed the SILC packet header to have the first two bytes
1261 (the packet length) encrypted. Affected files aroung the
1262 code tree, lib/silccore/silcpacket.[ch]. Removed the
1263 SilcPacketCheckDecrypt callback. It is not needed anymore
1264 since the silc_packet_receive_process will determine now
1265 whether the packet is normal or special.
1267 * Implemented the unidirectional MAC keys. Affected files
1268 lib/silcske/silcske.c, silcd/protocol.c and
1269 lib/silcclient/protocol.c.
1271 * Implemented the packet sequence number to the MAC computation.
1272 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1273 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1274 lib/silcclient/protocol.c.
1276 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1278 * Allow backup router to announce servers. All servers
1279 announced by backup router are added to the global list
1280 automatically. Update hte server's socket to our primary
1281 router also when backup router announces a server.
1282 Affected file silcd/packet_receive.c.
1284 * Do not update the client->router in the function
1285 silc_server_udpate_clients_by_server if the client is on
1286 global list. We might fail to find any specific server
1287 for locally connected clients and local cell clients. They
1288 should still use the `from' and not `to' as client->router.
1289 This fixes backup router resuming protocol. Affected file
1290 silcd/server_util.c.
1292 * Decrease channel statistics count only if the channel
1293 deletion worked. Affected files are silcd/server.c and
1294 silcd/server_util.c.
1296 * Added silc_server_update_servers_by_server to update origin
1297 of all server entries. Used during backup router protocol.
1298 Affected files silcd/server_util.[ch], silcd/server.c. and
1299 silcd/backup_router.c.
1301 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1302 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1303 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1304 lib/silccrypt/silchmac.c.
1306 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1308 * Assure that router cannot reroute the same channel message
1309 to the sender. Affected file silcd/packet_receive.c.
1311 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1313 * Made better checks that the channel message is not sent
1314 to the router it came from. Affected file is
1315 silcd/packet_send.c. Fixed memory leak too.
1317 * Announce informations for incoming router connection, but
1318 only after checking if it is replaced by backup router.
1319 Affected file silcd/packet_receive.c.
1321 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Fixed the backup resuming protocol to work in multiple
1324 router environment. Affected file silcd/server_backup.c.
1326 * Route packet only to one router in the function
1327 silc_server_packet_send_to_channel. Affected file is
1328 silcd/packet_send.c.
1330 * Fixed silc_server_send_notify_dest to set the broadcast
1331 flag. Fixed the silc_server_send_notify_topic to actually
1332 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1333 Affected file silcd/packet_send.c.
1335 * Changed the SFTP Filesystem interface. Changed the
1336 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1337 the filesystem operation function. The SilcSFTPFilesystem
1338 is now a context that is allocated by all filesystem allocation
1339 functions and it already includes the operations structure
1340 and filesystem specific context. It is given as argument
1341 now to the silc_sftp_server_start. This made the interface
1342 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1343 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1345 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Changed the backup router adding and getting interfaces
1348 in the server. The router that will be replaced by the
1349 specified backup router is now sent as argument. Affected
1350 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1353 * Added silc_net_addr2bin_ne to return the binary form of
1354 the IP address in network byte order. Affected files
1355 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1357 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1359 * Check for existing server ID in silc_server_new_server
1360 and in silc_server_connect_to_router_final and remove the
1361 old entry if it exists. Affected file silcd/packet_receive.c,
1364 * Send the channel message always to only one router, either
1365 in upstream or downstream. Affected file is
1366 silcd/packet_send.c.
1368 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Wrote the definition of the backup resuming protocol to the
1371 protocol specification.
1373 * Removed one redundant channel key generation from normal
1374 server during joining procedure. Removed one redundant
1375 channel key sending from server to router during joining
1376 procedure. Affected file silcd/command.c.
1378 * Made minor bugfixes to the backup router resuming protocol.
1379 Affected file silcd/server_backup.c, server.c.

1384 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1387 * Implemented the backup resuming protocol that is used to
1388 resume the primary router position in the cell after the
1389 primary router comes back online. Affected files
1390 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1391 and silcd/server_util.[ch].
1393 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * Sleep two (2) seconds after sending QUIT command to server.
1396 Affected file lib/silcclient/command.c.
1398 * Assure that if outgoing data buffer is pending do not force
1399 send any data. Affected file silcd/packet_send.c.
1401 * Assure that if outgoing data buffer is pending do not force
1402 send any data. Affected file lib/silcclient/client.c.
1404 * Implemented the backup router support when the primary router
1405 goes down. The servers and routers can now use the backup
1406 router as new primary router without loosing connectivity.
1408 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1411 in the server to indicate disabled entry. All data read
1412 from the connection will be ignored and no data is sent
1413 for entry that is disabled. Affected files are
1414 silcd/idlist.h, silcd/server.c.
1416 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Created SFTP client and server test programs in the
1419 lib/silcsftp/tests directory.
1421 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Implemented memory filesystem (virtual filesystem) for
1424 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1427 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Implemented the SFTP (SSH File Transfer Protocol) to the
1430 lib/silcsftp. It includes SFTP client and SFTP server
1433 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Moved lib/silccore/silcprotocol.[ch] to the
1436 lib/silcutil library.
1438 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1439 take variable argument list pointer as argument. Affected
1440 file lib/silcutil/silcbuffmt.[ch].
1442 * Added silc_buffer_set function that is used to set data
1443 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1444 Affected file lib/silcutil/silcbuffer.h.
1446 * Changed various routines in the core library to use the new
1447 silc_buffer_set instead of allocating new buffer only for
1450 * Added 64-bit value formatting and unformatting support to the
1451 silc_buffer_[un]format routines. Affected file is
1452 lib/silcutil/silcbuffmt.[ch].
1454 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1455 to includes/bitmove.h.
1457 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed channel user mode saving in client library. Affected
1460 file lib/silcclient/command[_reply].c.
1462 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Defined the file transfer to the SILC Protocol. Added
1465 new packet type SILC_PACKET_FTP and defined File Transfer
1466 Payload. The mandatory file transfer protocol is SFTP
1467 (SSH File Transfer Protocol). Affected file in addition
1468 of the internet draft is lib/silccore/silcpacket.h.
1470 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1471 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1472 is used as part of backup router protocol when the primary
1473 router of the cell is back online and wishes to resume
1474 the position as primary router.
1476 * Redefined the MAC generation keys in the protocol. The
1477 same key is not used anymore in both direction. Both
1478 direction will now use different keys for sending and
1479 receiving. This fixes a potential security flaw. This
1480 change causes incompatibilities in the protocol.
1482 * Redefined also the MAC computation from the packet.
1483 An packet sequence number is now added to the MAC
1484 computation. This prevents possible replay attacks against
1485 the protocol. This change too causes incompatibilities
1488 Added `sequence' field to the SilcPacketContext to hold
1489 the current sequence number for the packet.
1491 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Added `created' field to the SilcIDListData in the file
1494 silcd/idlist.h to indicate the time when the entry was
1497 * Added `created' field to the SilcChannelEntry too. Affected
1498 file silcd/idlist.h.
1500 * Added `creation_time' aguments to all the announcement functions
1501 in the server. If it is provided then only the entries that
1502 was created after the provided time frame are actually
1503 announced. Affected file silcd/server.[ch].
1505 * The protocol says that the Channel ID's IP address must be
1506 based on the router's IP address. Added check for this in
1507 the silc_server_new_channel when processing incoming New Channel
1508 Payload. Affected file silcd/packet_receive.c.
1510 * Print out the correct version with --version in SILC client.
1511 Affected file irssi/src/silc/core/silc-core.c.
1513 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1515 * Fixed WHOWAS command to check for completnes of the client
1516 entry always, not just when the command is coming from client.
1517 Affected file silcd/command.c.
1519 * Added new function silc_server_packet_queue_purge to purge the
1520 outgoing data queue to the network. After the function returns
1521 it is guaranteed that the outgoing packet queue is empty.
1522 Affected file silcd/packet_send.[ch].
1524 * Purge the outgoing packet queue in the rekey protocol's final
1525 callback to assure that all rekey packets go to the network
1526 before quitting the protocol. Affected file silcd/server.c.
1528 * Added silc_client_packet_queue_parse as similar function as
1529 in server to the client library. The affected file is
1530 lib/silcclient/client.c.
1532 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1534 * Splitted silcd/server.c and created silcd/server_util.[ch]
1535 for utility functions.
1537 * Added new socket flag SILC_SF_DISABLED to indicate that the
1538 connection is open but nothing can be sent to or received from
1539 the connection. Affected file lib/silcutil/silsockconn.[ch].
1540 The checking for disabled socket is checked in the low level
1541 silc_socket_write and silc_socket_read functions.
1543 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Allow only nicknames and channel names that fits into the
1546 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1548 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * When processing JOIN command reply in server check that if
1551 the channel exists in our global list we'll move it the local
1552 list. Affected file silcd/command_reply.c.
1554 * Fixed the check whether client is joined on the channel already
1555 in JOIN command. Affected file lib/silcclient/command.c.
1557 * Fixed the JOIN command reply to check whether the channel
1558 already exists. Affected file lib/silcclient/command_reply.c.
1560 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Added silc_ske_status_string to map the SKE error numbers
1563 to readable strings. The affected files are
1564 lib/silcske/silcske[_status].[ch].
1566 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1568 * Do not show the private channels on the WHOIS channel list
1569 as it is not allowed by the protocol. The affected file is
1572 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Assure that the packet length digged from the actual packet
1575 is something sensible in the silc_packet_decrypt_rest_special
1576 in lib/silccrypt/silcpacket.c.
1578 * Free and NULL the allocated pointer in silc_hmac_alloc if
1579 the HMAC allocation fails. The affected file is
1580 lib/silccrypt/silchmac.c.
1582 * Print the selected security properties to the log files in
1583 the server. Affected file silcd/protocol.c.
1585 * Add SKE's reference counter even if calling the completion
1586 callback manually. Otherwise it goes negative, although it
1587 does not cause any problems. The affected file is
1588 lib/silcske/silcske.c.
1590 * Remove the client entry with short timeout after giving the
1591 KILL command. Affected file lib/silcclient/command.c.
1593 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1594 case all found clients are already disconnected (WHOWAS would
1595 found them) in the server. Affected file silcd/command.c.
1597 * Update the last_receive (time of last data received) to be
1598 updated only when received private or channel message so that
1599 the idle time showed in WHOIS makes more sense.
1601 * Added boolean field `valid' in to the SilcClientEntry in the
1602 client library to indicate whether the entry is valid or not.
1603 This fixes the nickname change bug on channel when changing
1604 the nickname to be same than the old (like nick to Nick) the
1605 nickname formatter doesn't set the new nick anymore to Nick@host.
1606 Affected file lib/silcclient/idlist.[ch].
1608 * Now actually fixed the nickname changing on disconnection.
1609 Added new function silc_change_nick to the Irssi SILC Client.
1610 Affected file irssi/src/silc/core/client_ops.c,
1611 irssi/src/silc/core/silc-nicklist.[ch].
1613 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Check that the public key exists in the GETKEY command before
1616 trying to encode it. Affected file silcd/command.c.
1618 * Print some notifications on received public keys with GETKEY
1619 command in the Irssi SILC Client. Affected files are
1620 irssi/src/fe-common/silc/module-formats.[ch],
1621 irssi/src/silc/core/client_ops.c.
1623 * Use IDENTIFY command to resolve the server information in the
1624 GETKEY command instead of INFO command. Affected file
1625 lib/silcclient/command.c.
1627 * All command reply functions in the client library now calls
1628 the pending command reply callbacks even if an error has
1629 occurred. The server has done this a long time and now it was
1630 time to move the client library to this as well. Now all
1631 errors can be delivered back to the pending command reply
1632 callbacks if necessary. Affected files are
1633 lib/silcclient/command[_reply].[ch].
1635 * Change the nickname on disconnection back to the username
1636 because in reconnect the server will enforce it to it anyway.
1637 Affected file irssi/src/silc/core/silc-servers.c.
1639 * Fixed a config file parsing bug in the Irssi SILC client.
1640 Affected file irssi/src/silc/core/clientconfig.c.
1642 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * When printing the channel mode on JOIN, verify that the
1645 channel key and channel's HMAC are valid. Affected file
1646 irssi/src/silc/core/client_ops.c.
1648 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1651 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1652 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1654 * Removed channel key rekey task deleting from the function
1655 silc_server_save_channel_key. Affected file silcd/server.c.
1656 Added explicit timeout task context instead that is used to
1657 delete the task if we are registering a new task before the
1658 new task has elapsed.
1660 * When channel key rekey occurs the client library now saves
1661 the old channel key for a short period of time (10 seconds) and
1662 is able to use it in case some is still sending channel
1663 messages encrypted with the old key after the rekey. Affected
1664 file lib/silcclient/[idlist.h|client_channel.c].
1666 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Added check to the silc_server_new_id_real to not accept
1669 new ID if it is the sender's own ID. Affected file is
1670 silcd/packet_receive.c.
1672 * Assure that we do not announce ourself or the one we've
1673 sending our announcements when we're router and are announcing
1674 servers to our primary router. Affected file silcd/server.c.
1676 * Fixed silc_server_command_identify_check_client to assemble
1677 correct WHOIS packet. It send corrupted WHOIS packet and
1678 caused problem with router to router connections. Affected
1679 file silcd/command.c.
1681 Fixed also silc_server_command_whois_check the same way
1682 as for the IDENTIFY command.
1684 * Added new SilcIDListStatus to the server in the SilcIDListData
1685 structure. The status now includes the current status of
1686 the entry (like registered, resolved etc.). Affected file
1687 silcd/idlist.[ch]. Defined a bunch of different status types
1688 as well. This replaced the old boolean registered field as well.
1690 Added resolve_cmd_ident field to the SilcClientEntry structure
1691 too so that if the entry is for example being resolved so
1692 another command may attach to the same pending command reply
1693 without requiring to resolve the same entry again. This concept
1694 should optimize the WHOIS and the IDENTIFY resolving under
1695 heavy load by taking away unnecessary resolving for entries
1696 that are being resolved already.
1698 Added support for adding multiple pending commands for one
1699 command idenfier. Affected file silcd/command[_reply].[ch].
1701 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1702 before deleting the data. Otherwise the hash table will have
1703 freed data in comparison functions. Affected file is
1704 silcd/command_reply.c.
1706 * Fixed silc_idlist_replace_client_id to add the new entry to
1707 the cache with NULL nickname. Otherwise there will be invalid
1708 memory as the nickname after the nickname is freed. Affected
1709 file silcd/packet_receive.c.
1711 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1712 saved into wrong slots because the previous number of entries
1713 was not taken into account. Affected file silcd/idlist.c.
1714 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1716 * If we are router and we receive JOIN notify to a channel that
1717 does not have any users then notified client is marked as the
1718 channel founder, as it is it. The affected file is
1719 silcd/packet_receive.c
1721 * Added to the extended hash table API's table_del_*ext functions
1722 the destructor as argument too, so that the caller can decide
1723 which destructor to use or whether to use destructor at all.
1724 Affected file lib/silcutil/silchashtable.[ch].
1726 * Fixed ID Cache purging. It actually deleted the entries from
1727 the hash table after the data was freed. The hash table ended
1728 up comparing freed memory. The affected file is
1729 lib/silccore/silcidcache.c.
1731 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1733 * Fixed Irssi SILC client's KILL command's HELP syntax.
1735 * The USERS command now resolves the detailed user information
1736 if the userinfo field is missing. Affected file is
1737 lib/silcclient/command_reply.c.
1739 * Do not print error in silc_file_read if the read file does
1740 not exist. Just silently return NULL. Affected file is
1741 lib/silcutil/silcutil.c.
1743 * Fixed the silc_log_output to not wine about NULL filename
1744 and to not create some bogus " " filename. Affected file is
1745 lib/silcutil/silclog.c.
1747 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * Fixed various printing bugs on the user interface in the
1750 Irssi SILC Client. Minor changes that were forgotten from
1753 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1755 * Fixed the configure.in.pre and the compilation and distribution
1756 environment to support the new autoconf 2.52. That version is
1757 now required to compile the CVS trunk.
1759 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1761 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1762 to generally parse user@fqdn format strings. Affected file
1763 lib/silcutil/silcutil.c.
1765 * Added nickname_format and nickname_force_format fields to the
1766 SilcClientParams structure. The first one defines the format
1767 for the nicknames that the library will enforce if the receives
1768 multiple same nicknames. The second one is boolean value and
1769 can be used to force the library to always enforce the format
1770 to the nicknames regardles whether there are multiple nicknames
1771 or not. This configurable formatting was employed to flexibly
1772 support accessing multiple nicknames from the user interface.
1773 The userinterface can now set the nicknames to what ever format
1774 they prefer. Affected file lib/silcclient/silcapi.h.
1776 Added function silc_client_nickname_format to the file
1777 lib/silcclient/idlist.c. It performs the nickname formatting.
1779 Added new field `hostname´ to the SilcClientEntry context.
1780 It holds the hostname of the client. Affected file is
1781 lib/silcclient/idlist.h.
1783 * Irssi SILC Client sets the nicknames in nick@hostn format.
1784 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1785 irssi/src/silc/core/silc-core.c.
1787 The WHOIS printing now also shows both the real nickname and
1788 the formatted nickname so that user knows how to access the
1789 user if there are multiple same nicknames cached. Affected
1790 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1791 printing formatting too to take the hostname now as a separate
1792 argument. The Affected file is
1793 irssi/src/fe-common/silc/modules-formats.[ch].
1795 * Changed the silc_client_get_clients_local to accept the formatted
1796 nickname as argument. It accepts the real nickname too but the
1797 formatted nickname can be used to find the true entry from
1798 multiple entries. Affected file lib/silcclient/silcapi.h and
1799 lib/silcclient/idlist.c.
1801 * Added nickname_format_parse field to the SilcClientParams.
1802 It is a callback function provided by the application to parse
1803 the nickname out of the formatted nickname string. The library
1804 calls it to get the nickname from the formatted string. Since
1805 the application generally knows better the format of the nickname
1806 string it parses it instead of the library, even though library
1807 encodes the formatted string. If the callback function is not
1808 provided then the library will use the string as is. The
1809 affected file is lib/silcclient/silcapi.h.
1811 * All the nickname strings passed to the client library in
1812 commands are now expected to be formatted nickname strings.
1813 If the command does not support the formatted nickname string
1814 it will assume that the sent string is the actual nickname.
1815 Affected file lib/silcclient/command.c.
1817 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Added public key authentication support to OPER and SILCOPER
1820 commands in the client library. Affected file is
1821 lib/silcclient/command.c.
1823 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Changed the get_auth_methdod client operation to be asynchronous.
1826 It can be async if the application resolves the authentication
1827 method from the server during the negotiation. Added new
1828 SilcGetAuthMeth completion callback that the application will
1829 call after resolving the authentication method.
1831 Added function silc_client_request_authentication_method that
1832 the application can use to resolve the authentication method
1833 from the server. Added also SilcConnectionAuthRequest callback
1834 that the library will call after the server has replied. The
1835 application can call this function if it does not know the
1836 current authentication method.
1838 Affected files are lib/silcclient/client.c and
1839 lib/silcclient/silcapi.h.
1841 * The Irssi SILC client now automatically resolves the authentication
1842 method incase any configuration information is not present (and
1843 currently there never is). The affected file is
1844 irssi/src/silc/core/client_ops.c.
1846 * Fixed public key authentication from the client library.
1847 Affected file lib/silcclient/protocol.c. Changed also the
1848 protocol specification about the public key authentication in
1849 the connection authentication protocol. The actual data to be
1850 signed is now computed with a hash function before signing.
1852 * Fixed the public key authentication from the server as well.
1853 Affected file silcd/protocol.c.
1855 * Removed the mlock()'s from the memory allocation routines.
1856 Affected file lib/silcutil/silcmemory.c. The ./configure does
1857 not check anymore for the mlock(). Affected file is
1860 * Fixed USERS command in server to allow the execution of the
1861 command for private and secret channels if the client sending
1862 the command is on the channel. Affected file silcd/command.c.
1864 * Fixed silc_client_get_clients_local to return the clients
1865 count correctly. It could return wrong value. Affected file
1866 lib/silcclient/idlist.c.
1868 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1870 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1871 types. The assembler optimizations seemed not to like 64-bit
1872 data types. The assmebler optimizations thus are now enabled
1873 also for BSD systems as opposed to only enable them for Linux.
1875 * Do not check for threads at all on BSD systems. Affected
1876 file configure.in.pre.
1878 * Removed -n and -h options from the Irssi SILC Client since
1879 they are not used in silc.
1881 * Fixed the prime generation to assure that the first digit
1882 of the generated random number is not zero since our conversion
1883 routines does not like number strings that starts with zero
1884 digit. If zero digit is seen the random number is regenerated.
1885 This caused some corrupted RSA keys when the zero first digit
1886 was met. Affected file lib/silcmath/silcprimegen.c.
1888 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Fixed WIN32 configuration in the ./configure script.
1891 Fixed to include xti.h on environments that has it.
1892 Patches by Carsten Ilchmann and andrew.
1894 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * Changed the silc_id_create_client_id to be collision
1897 resistant. It is now assured that there cannot be created
1898 two same client ID's. I suspect that some weird bugs in
1899 the server were actually caused by duplicate Client IDs.
1900 Affected file silcd/serverid.[ch]. A router receiving
1901 new ID now also assures and informs the sending server
1902 if the ID caused collision.
1904 * Changed the silc_id_create_channel_id to also assure that
1905 there are no collisions.
1907 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Statement about ignoring the Mutual Authentication flag when
1910 performing rekey with PFS was a bit misleading. It is ignored
1911 if it was set in the initial negotiation, it cannot be even
1912 set in the rekey. Fixed in the ke-auth draft. Started the
1913 new versions of the protocol drafts in the doc/.
1915 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Fixed a bug in silc_client_command_identify_save when saving
1918 new channel information. The channel name was no duplicated
1919 and caused crash on exit. Affected file is
1920 lib/silcclient/command_reply.c.
1922 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Fixed the getkey command handling in the server. Send just
1925 empty OK reply to the sender if the key could not be fetched
1926 (but everything else was ok, like the key just was not available).
1927 Changed the public key parameter to optional in the protocol
1928 specs so that empty OK reply can be sent. Affected file
1931 Added a message to Irssi SILC client to tell to user if the
1932 server did not return a public key.
1934 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Fixed a channel key regeneration bug. It registered new
1937 timeout tasks exponentially until all system resources were
1938 used. Affected file silcd/server.c.
1940 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Added the SILC Document generator to the scripts/silcdoc.
1943 It can be used to generate the Toolkit Reference Manual out
1944 of the source tree. Internally it will also use the RoboDoc
1945 generator now imported in util/robodoc.
1947 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Added couple of return's in rekey protocol if error orccurred
1950 during the protocol. The execution must be terminated.
1951 Affected file silcd/protocol.c. Also, terminate the protocol
1952 always with timeout.
1954 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * The client's Client ID was created initally from the wrong
1957 nickname (it could have been in format nick@host) in the
1958 silc_server_new_client. Affected file silcd/packet_receive.c
1960 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Added some SILC_LOG_ERROR's to various error conditions
1963 if client could not be added to ID cache. Affected files
1964 silcd/packet_receive.c and silcd/server.c.
1966 * When client's sock->user_data is freed, NULL also the
1967 client->router and client->connection pointers. Added check
1968 for these pointers being NULL to various places around the
1969 code. Affected file silcd/server.c.
1971 * Added client->data.registered == TRUE checks to various
1972 places around the code to assure that unregistered client's
1973 are not handled when it is not allowed. Affected file
1976 * Added `bool registered' fields to all
1977 silc_idlist_[server|client]_get_* routines to indicate whether
1978 the fetched client needs to be registered or not. Affected
1979 file silcd/idlist.[ch].
1981 * Add your own entry as registered to the ID cache in the
1982 server. Affected file server.c.
1984 * Fixed a bug in silc_server_new_server. The SilcServer was
1985 set as the new server's context instead of SilcServerEntry.
1986 This naturally caused some weird bugs.
1988 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1990 * Do not delete the channel rekey task when adding it
1991 for in silc_server_create_channel_key.
1993 * Changed the silc_server_create_channel_key to return
1994 TRUE or FALSE to indicate the success of the channel key
1997 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1999 * Fixed MSVC++ project files and added missing files to
2000 Makefiles under win32/.
2002 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2004 * Do not add TCP_NODELAY flag if the operating system
2005 does not have it defined. Affected files are
2006 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2008 * Fixed buffer overflow from Irssi SILC Client. Affected
2009 file irssi/src/fe-common/core/themes.c.
2011 * Fixed double free in client library in the file
2012 lib/silcclient/client.c when disconnecting from server.
2014 * Applied double free patch from cras to Irssi SILC client.
2015 Affected files irssi/src/core/[modules/expandos].c
2017 * Fixed the disconnection handling to Irssi SILC Client.
2018 The application must call silc_client_close_connection
2019 in ops->connect client operation in case of failure of
2020 the connection. Affected file is
2021 irssi/src/silc/core/client_ops.c.
2023 * Do not set sock->protocol to NULL in the function
2024 silc_client_close_connection after executing the protocol's
2025 final callback since the sock might not be valid anymore.
2026 Affected file lib/silcclient/client.c.
2028 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2030 * Do not enable SILC_THREADS if the linking with libpthread
2031 did not happen. Affected file configure.in.pre.
2033 * Added notion to protocol specification that server must
2034 verify the sent authentication payload with CMODE when
2035 setting the channel founder key. Implemented it to the
2036 server. Affected file silcd/command.c.
2038 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Added _EXTRA_DIST SILC distribution variable to the
2041 distributions file. It is used to conditionally add extra
2042 files or directories to the specific distribution. Affected
2043 files ./prepare, Makefile.am.pre and distributions.
2045 Removed the `_' from the start of the distribution names.
2048 * Added README.WIN32 for instructions to compile the Toolkit
2051 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2053 * Fixed a double free in disconnection in the server. Affected
2054 file is silcd/server.c.
2056 * Fixed the lib/silcske/groups.c to work now also with GMP
2057 MP library. The string conversion did not work when using
2058 specific base and the base is indicated in the string as well.
2060 * Created win32/ directory which now includes MSVC++ specific
2061 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2062 It will appear only in the toolkit distribution
2064 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Changed the key material distribution function in case when
2067 the hash output is too short. The data is now concatenated
2068 a bit differently than it used to. Made the change to the
2069 SKE protocol specification.
2071 * Added better GMP detection to configure.in.pre. A patch
2074 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2076 * Fixed a minor bug in SKE that might cause some problem on
2077 some platforms. Affected file lib/silcske/silcske.c.
2079 * Added the cookie checking for initiator in the SKE. It checks
2080 that the responder returns the sent cookie unmodified. The
2081 affected file is lib/silcske/silcske.c. Added new SKE
2082 error type INVALID_COOKIE that can be sent during the
2083 negotiation. Fixed some memory leaks as well.
2085 * Added the "invalid cookie" error message to Irssi SILC client's
2088 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Added `task_max' field to the SilcClientParams to indicate
2091 the maximum tasks the scheduler can handle. If set to zero,
2092 default values are used. Affected file lib/silcclient/silcapi.h.
2094 * Fixed memory leaks in silc_client_close_connection. Affected
2095 file lib/silcclient/client.c.
2097 * Added silc_client_del_client_entry to client library to free
2098 all memory of given client entry. Affected file is
2099 lib/silcclient/idlist.[ch].
2101 * Added new functions silc_client_del_channel and
2102 silc_client_del_server to delete channel and server entries.
2103 Affected file lib/silcclient/[silcapi.h/idlist.c].
2105 * Removed silc_client_del_client_by_id from silcapi.h.
2107 * Fixed the INFO command to return the server's own info
2108 correctly when querying by Server ID. Affected file is
2111 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2113 * Removed the non-blocking settings in WIN32 code in the
2114 silc_sock_[read/write] and added SleepEx instead. Affected
2115 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2116 of input data is now checked with FIONREAD and ioctlsocket.
2118 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2120 * Call silc_schedule_task_del_by_context in the
2121 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2122 Affected file lib/silccore/silcprotocol.c.
2124 * Call silc_protocol_cancel for active protocols in the
2125 silc_server_close_connection if the funtion
2126 silc_server_free_sock_user_data has not been called.
2127 Affected file silcd/server.c.
2129 * Generic tasks cannot be deleted using the del_by_fd
2130 task deleting function since generic tasks does not match
2131 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2133 * Added a notion to SILCOPER help file that the SILCOPER works
2134 only on router server, not on normal server.
2136 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Added for WIN32 support for the new scheduler as well.
2139 Affected file lib/silcutil/win32/silcwin32schedule.c.
2141 * Fixed the SHA1 implementation to work on various platforms.
2143 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2146 API. It is part of the scheduler now. Everything else is
2147 as previously but some functions has changed their names.
2148 Checkout the lib/silcutil/silcschedule.h for the interface.
2149 Updated all applications to use the new interface. Affected
2150 files are lib/silcutil/silcschedule.[ch].
2152 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Found a bug in the SKE implementation. The HASH value,
2155 specified by the protocol, was not computed correctly. The
2156 public key of the responder was not added to the computation
2157 even though it is mandatory. Affected file lib/silcske/silcske.c.
2158 This unfortunately causes incompatibilities with older
2159 clients and servers.
2161 * Added WIN32 specific network init and uninit functions:
2162 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2163 the Winsock2. Affected file lib/silcutil/silcnet.h and
2164 lib/silcutil/win32/silcwin32net.c.
2166 * Set the socket always to nonblocking mode on WIN32 after
2167 reading data or writing data. Affected file is
2168 lib/silcutil/win32/silcwin32sockconn.c.
2170 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Fixed various compilation problems under WIN32. Affected
2173 files lib/silcutil/win32/silcwin32thread.c and
2174 lib/silcutil/win32/silcwin32schedule.c.
2176 * Removed all _internal.h #includes from public header
2177 files. Internal headers must never be included from
2180 Removed also the lib/silcske/payload_internal.h file.
2182 * All include files that may be needed (public and some others
2183 included by the public headers) by application developers are
2184 now copied to the ./includes directory. It does not copy any
2185 internal headers. Affected file Makefile.defines.pre and all
2186 Makefile.am's under lib/ and subdirs.
2188 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Do not change the ~/.silc directory's permissions automatically.
2191 Affected file irssi/src/silc/core/clientutil.c.
2193 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Do not cancel the protocol in silc_server_close_connection
2196 it might cause recursion. Now cancelled in the function
2197 silc_server_free_sock_user_data. Affected file silcd/server.c.
2199 * Fixed the silc_server_remove_clients_by_server to regenerate
2200 the channel keys correctly finally. Added also new function
2201 silc_server_remove_clients_channels to actually do it.
2202 Affected file silcd/server.c.
2204 * Fixed the silc_server_new_channel to not crash by giving
2205 wrong router to the new channel. Affected file is
2206 silcd/packet_receive.c.
2208 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2211 which is given as argument to the silc_client_alloc now.
2212 It can be used to configure the client and set various parameters
2213 that affect the function of the client.
2215 * The USERS command in server did not check whether the channel
2216 is private or secret. Affected file silcd/command.c.
2218 * Added new argument to the USERS command in protocol specification.
2219 The USERS command now can take the channel name as argument
2220 as well. Added support for this in client and server and
2221 updated the protocol specs.
2223 * Completed the GETKEY command in client. It can be now used
2224 to fetch also servers public key not only some clients.
2225 Affected files lib/silcclient/command[_reply].c.
2227 * Added silc_client_get_server to return server entry by the
2228 server name. Affected files lib/silcclient/silcapi.h and
2231 * Redefined the IDENTIFY command in protocol specification to be
2232 more generic. It now can be used to query information about
2233 any entity in the SILC Network, including clients, servers and
2234 channels. The query may be based either the entity's name
2235 or the ID. Added support for this in both client and server.
2237 Affected files silcd/command.c and lib/silcclient/command.c
2238 and command_reply.c.
2240 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2241 the _from_client and _from_server functions. Affected file
2244 * Added silc_client_get_channel_by_id_resolve to the file
2245 lib/silcclient/silcapi.h to resolve channel information by
2246 its ID. Added also silc_client_get_channel_by_id that
2247 does not resolve it from the server.
2249 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2251 * Added SilcServerEntry context into the client library
2252 to represent one server. The INFO command now allocates
2253 these to save the resolved server info. For now on the
2254 client library will also keep information about servers,
2255 connected and resolved with INFO.
2257 The INFO command now allocates the SilcServerEntry context
2258 and saves the server info there. The COMMAND_REPLY in
2259 the INFO now returns the parameters to application in
2260 same order as defined in the protocol specification.
2262 The entries are cached in the client->server_cache.
2264 * The INFO command is now issued after received the Client ID
2265 from the server. Affected file lib/silcclient/client.c.
2267 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2268 to the application as the mode changer might be server.
2269 It is guaranteed that NULL is not returned anymore to the
2270 application. Affected file lib/silcclient/client_notify.c.
2272 The ID Type is now also passed to the application so that
2273 it can check whether the returned entry is SilcClientEntry
2276 Added new function silc_client_get_server_by_id to return
2277 the server entry by ID. Affected files are the
2278 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2280 * Do not create the channel in the Irssi SILC Client when issuing
2281 the JOIN command but when received the sucessful JOIN command
2282 reply. Otherwise the channel might get created even though we
2283 could not join it. The Affected file is
2284 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2286 * Fixed a channel joining bug in router. The router must also
2287 check the channel modes, invite and ban lists etc. when serving
2288 the JOIN command sent by normal server. Affected file is
2289 silcd/command.c. The router now resolves the client's
2290 information from the server who sent the JOIN command if it
2291 does not know it, and processes the JOIN command only after
2294 * Changed the SilcCommandCb to take new argument; void *context2.
2295 Affected file lib/silccore/silccommand.h
2297 The second argument in the command callbacks in the server now
2298 includes the SilcServerCommandReplyContext if the command was
2299 called as pending command callback from the command reply.
2300 Otherwise it is NULL. When called as pending the status of the
2301 command reply will be checked and if it was erronous the
2302 error will be sent to the original sender of the command.
2303 This way the client always receives the error messages even
2304 though the server was actually the one who received the error
2305 when it resent the command to router, for example. Affected
2306 files silcd/command[_reply].[ch].
2308 * Fixed sending WHOWAS command's error message to client if
2309 the requested client could not be found. It was missing.
2312 * Changed the CMODE and CUMODE commands reply arguments in the
2313 protocol specification. The Channel ID is now sent in both
2314 of the commands to identify the channel. Implemented this
2315 new feature to the client and server. Affected files
2316 lib/silcclient/command_reply.c and silcd/command.c.
2318 * Made better checks for invite and ban lists in the JOIN
2319 command in server. Affected file silcd/command.c.
2321 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * The server now performs the incoming host IP/DNS lookup
2324 using the silc_socket_host_lookup and thus does not block
2325 the server anymore. Affected file silcd/server.c.
2327 * Completed the multi-thread support for SILC Scheduler in
2328 the lib/silcutil/silcschedule.c.
2330 * Fixed the configure.in.pre to detect the pthread correctly
2333 * Fixed a deadlock in silc_task_queue_wakeup in the file
2334 lib/silcutil/silctask.c.
2336 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Added new function silc_schedule_wakeup that is used in
2339 multi-threaded environment to wakeup the main thread's
2340 schduler. It needs to be used when a thread adds a new task
2341 or removes a task from task queues. After waking up, the
2342 scheduler will detect the task queue changes. If threads
2343 support is not compiled in this function has no effect.
2344 Implemented the wakeup mechanism to both Unix and WIN32
2345 systems. Affected files are lib/silcutil/silcschedule.[ch],
2346 lib/silcutil/unix/silcunixschedule.c and the
2347 lib/silcutil/win32/silcwin32schedule.c.
2349 * Added new function silc_task_queue_wakeup to wakeup the
2350 scheduler by the specified task queue. Affected file
2351 lib/silcutil/silctask.[ch].
2353 * The silc_socket_host_lookup_start now wakes up the scheduler
2354 after adding the timeout task. Affected file is
2355 lib/silcutil/silcsockconn.c.
2357 * The silc_socket_host_lookup is synchronous now if the threads
2358 support is not compiled in. However, the callback is still
2359 called asyncronously through the scheduler, anyway. Affected
2360 file lib/silcutil/silcsockconn.c.
2362 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Added new function silc_socket_host_lookup to perform
2365 asynchronous IP and FQDN lookups for the socket connection.
2366 Affected files lib/silcutil/silcsockconn.[ch].
2368 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2370 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2371 that may or may not compile the mutex support in.
2373 Changed the silc_mutex_alloc interface. It allocates the
2374 mutex now to the sent pointer and returns TRUE or FALSE.
2376 Affected file lib/silcutil/silcmutex.h.
2378 * Wrote the SILC Task Queue interface to support multi-threads.
2379 Affected file lib/silcutil/silctask.[ch].
2381 * Wrote the SILC Scheduler to support multi-threads. Affected
2382 file lib/silcutil/silcschedule.c.
2384 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2386 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2387 in lib/silcutil/win32/.
2389 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Defined SILC Mutex API and SILC Thread API and implemented
2392 them for Unix. Affected files are
2393 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2394 lib/silcutil/unix/silcunixmutex.c and
2395 lib/silcutil/unix/silcunixthread.c.
2397 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Fixed the silc_server_remove_clients_by_server's channel
2400 key re-generation. The hash table handling was incorrect
2401 and would not work with many channels. Affected file is
2404 * Fixed some memory leaks around the server code.
2406 * Rewrote the silc_server_get_users_on_channel to support IPv6
2407 based Client ID's. Affected file silcd/server.c.
2409 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2410 specification. However, a separate document must be written
2411 to define the detailed signing procedure and the payload
2412 associated with the flag. Defined the flag to the
2413 lib/silccore/silcchannel.h as well.
2415 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Changed the dynamic tables to static size tables in the
2418 lib/silccrypt/silchmac.c.
2420 * Removed GCC dependencies from the code. A patch by cras.
2422 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Do not show the error "Error receiving packet bla bla"
2425 in server if it really was not an error (-2 means that reading
2426 is pending). Affected file silcd/server.c.
2428 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Fixed a possible crash in silc_server_remove_clients_by_server
2431 in silcd/server.c. Fixed there also some memory leaks.
2433 * Fixed the silc_idlist_replace_client_id. It could replace
2434 wrong key in the hash table. Affected file silcd/idlist.c.
2436 * Do not check whether there are global users on the channel
2437 if the channel->global_users is FALSE. Affected functions
2438 silc_server_remove_from_one_channel and
2439 silc_server_remove_from_channels in silcd/server.c. Also,
2440 do not check if the removed client is local as we can be
2441 sure that global client was not removed from the channel
2442 and checking for global users is not needed.
2444 * The silc_server_remove_clients_by_server now re-generates
2445 the channel keys correctly for those channels that had
2446 clients removed from them. Affected file silcd/server.c.
2448 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Found the reason of random crashes in the server. We weren't
2451 ignoring the SIGPIPE signal (which can be sent in write())
2452 and it crashed the server. Affected file silcd/silcd.c.
2454 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2456 * Assure that sock->user_data is not NULL in the function
2457 silc_server_packet_send in silcd/packet_send.c.
2459 * Disconnect the remote connection if it could not be added
2460 to any ID lists in the server. The affected file is
2463 * Check in silc_server_packet_send[_real/dest] that the
2464 socket is not disconnecting and ignore the data if it is.
2465 Affected file silcd/packet_send.c.
2467 * Define inline to __inline on native WIN32 compilation.
2468 Affected file includes/silcwin32.h.
2470 * Added some explicit type casts for inline code since MSVC
2471 require them. Affected files lib/silcutil/silcbuffer.h,
2472 lib/trq/silcdlist.h and lib/trq/silclist.h.
2474 * Print warning in log files from now on if the packet
2475 decryption fails. Affected file silcd/server.c.
2477 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2479 * Changed the `say' client operation's interface to accept
2480 new `type' argument to indicate the type of the message sent
2481 by the library. The application may filter the library's
2482 messages according the type. The affected file is the
2483 lib/silcclient/silcapi.h.
2485 * Added two new functions to lib/silcclient/silcapi.h:
2486 silc_client_del_client and silc_client_del_client_by_id.
2487 Affected file lib/silcclient/idlist.c.
2489 * Moved the clientincludes.h from includes/ to silc/ and
2490 serverincludes.h from includes/ to silcd/.
2492 * The modes for the CMODE and CUMODE are now passed as
2493 uint32 for application with COMMAND_REPLY. The affected
2494 file is lib/silcclient/command_reply.c.
2496 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * /WHOIS without arguments shows client's own information.
2499 Affected file lib/silcclient/command.c.
2501 * Changed PING to not accept any arguments. The specs
2502 says that client can ping only the connected server so
2503 requiring an argument is not needed. Affected file is
2504 lib/silcclient/command.c.
2506 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Fixed a fatal bug in private message sending and reception
2509 encryption and decryption when using private message keys.
2510 The implementation was incorrect and did not follow the
2511 specification. It causd that some of the message were
2512 lost since it did not use the sending and receiving keys
2513 as the protocol suggests. This has been fixed and will cause
2514 incompatibilities with older clients when sending private
2515 message encrypted with private message keys. Affected files
2516 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2517 and various other in Irssi SILC Client.
2519 Added `responder' boolean argument to the functions
2520 silc_client_add_private_message_key[_ske] to indicate when
2521 the key is added as responder or initiator of the key
2524 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Removed the silc_ske_check_version function and created
2527 a SilcSKECheckVersion callback. Added also a function
2528 silc_ske_set_callbacks that is now used to set all SKE
2529 callbacks. The callback functions are not given to
2530 the SKE functions anymore, but this function is used to
2533 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2535 * Added `silc_version' argument to the silc_client_alloc
2536 to define the version of the application for the library.
2537 The library will use the version string to compare it
2538 against the remote host's (usually a server) version
2539 string. Affected file lib/silcclient/silcapi.h
2541 * Added the KE protocol context to Key Agreement context
2542 in client library so that we can abort the SKE if it
2543 is in process when we get timeout. Affected file is
2544 lib/silcclient/client_keyagr.c.
2546 * Do not resolve the client ID forever if it returns in the
2547 first time that such client does not exist. This was done
2548 for example with private message. Affected file is
2549 lib/silcclient/client_prvmsg.c.
2551 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Do not add regex.h for WIN32. The affected file
2554 includes/silcincludes.h.
2556 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2557 not work yet 100%. It generates the DLL's automatically
2558 when compiling with --with-win32 under cygwin.
2560 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2562 * lib/contrib/regex.c is not compiled on WIN32.
2564 * Added silc_net_get_socket_opt function to the
2565 lib/silcutil/silcnet.h.
2567 * Added includes/silcwin32.h for WIN32 specific includes
2570 * Do not use ptime structure or any of the posix process
2571 functions on WIN32 in lib/silccrypt/silrng.c.
2573 * Added silc_gettimeofday to provide generic function
2574 for struct timeval on all platforms. Added the function
2575 to lib/silcutil/silcutil.h.
2577 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2580 library as they clearly belong there. As a plus side we
2581 can make the actual socket connection routines platform
2584 Added also new generic function silc_socket_read and
2585 silc_socket_write (that used to be silc_packet_[read/write].
2586 The implementation of these are platform specific.
2588 * Added WIN32 specific routines of silc_socket_[read/write]
2589 to lib/silcutil/win32/silcwin32sockconn.c.
2591 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Added preliminary support for native WIN32 compilation under
2594 cygwin (using the -mno-cygwin option for GCC) to the
2595 ./configure.in.pre. The --with-win32 now prepares the
2596 compilation for native WIN32.
2598 * Rewrote the SILC Scheduler interface in the file
2599 lib/silcutil/silcschedule.h. The scheduler is now context
2600 based and does not have anymore any global static scheduler.
2601 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2602 and created lib/silcutil/win32 directory for WIN32 based
2605 * Added Unix specific network routines to the
2606 lib/silcutil/unix/silcunixnet.c and the old
2607 lib/silcutil/silcnet.c includes now only generic routines.
2609 Added WIN32 specific network routines to the
2610 lib/silcutil/win32/silcwin32net.c.
2612 * Added Unix specific utility functions from the
2613 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2615 * Added WIN32 SILC Scheduler to the file
2616 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2619 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Do not handle JOIN notify in the server if the target client
2622 is not registered (idata->registered == FALSE). The affected
2623 file is silcd/packet_receive.c.
2625 * Update the nickrec->founder in event_cumode in the Irssi SILC
2626 client. Affected file irssi/src/silc/core/silc-channels.c.
2628 * Fixed the CUMODE_CHANGE notify handling in the server when
2629 server and router are announcing their clients on channels.
2630 Now the mode changes are saved and notified correctly. The
2631 affected file is /silcd/packet_receive.c.
2633 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2634 They really did not replace the cache entry in the ID Cache.
2635 Now they do that. Affected file silcd/idlist.c.
2637 * Fixed the KICK notify handling in the Irssi SILC client to
2638 update the channel records so that the kicked client does not
2639 appear to be on the channel. The affected file is
2640 irssi/src/silc/core/silc-channels.c.
2642 * Always update the conn->current_channel when executing command
2643 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2645 * Fixed the KILL notify handling in Irssi SILC client to remove
2646 the killed client on all channels.
2648 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Fixed the silc_parse_command_line to remove extra spaces
2651 from the start and end of the arguments. Affected file is
2652 lib/silcutil/silcutil.c.
2654 * Cancel and free any active protocol in the function
2655 silc_server_close_connection. Affected file silcd/server.c.
2657 * Cancel and free any active protocol in the function
2658 silc_client_close_connction. Affected file is
2659 lib/silcclient/client.c.
2661 * Do not execute the KILL command for clients that are in
2662 history (ie. they are not in the network). Affected file is
2665 * Fixed KILL notify handling, client does not crash anymore.
2666 Affected file irssi/src/silc/core/silc-channels.c.
2668 * Reduced the default packet buffer size from 2048 to 1024 in
2669 lib/silccore/silcpacket.c.
2671 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2672 counter to the SKE context that is incresed when the SKE library
2673 performs async operation outside the library. If the outside
2674 process frees the SKE context and FREED status will be set
2675 and the library will detect after the sync operation that the
2676 libary is freed. The affected files are
2677 lib/silcske/silcske[_status].[ch].
2679 * Resolve the client entry information in the function
2680 silc_client_channel_message to assure that NULL pointer is not
2681 passed as client entry to the application. */
2683 * Fixed the task timeout calculation to assure that there is
2684 never negative timeouts. The affected file is
2685 lib/silcutil/silcschedule.c.
2687 * Fixed the channel user mode notification sending in server.
2688 It was sent point-to-point to the router (or to server by router)
2689 but it needs to be destined to a channel. The routines now
2690 supports sending the channel user mode notifys to the channels
2691 when announcing clients and channels. Affected files are
2692 silcd/server.c and silcd/packet_receive.c.
2694 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2695 It did not actually replace the old channel entry in the cache.
2696 Affected file lib/silcclient/client_notify.c.
2698 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Fixed a possible crash in silc_packet_send_prepare. It now
2701 assures always that there is enough space in the buffer and
2702 at the tail area of the buffer (for MAC).
2704 Fixed the inbound buffer reallocation in silc_packet_read.
2705 It was old code and did not handle the reallocation correctly.
2708 The affected file is lib/silccore/silcpacket.c.
2710 * Fixed buffer overflow in silc_parse_nickname in the file
2711 lib/silcutil/silcutil.c.
2713 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * make install generates new server keys only if there is not
2718 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2720 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2721 Added check that if the NOREPLY is set then we will not send
2722 the away message. This avoids infinite loop of away messages
2723 if both clients are away. The affected file is
2724 lib/silcclient/client_prvmsg.c.
2726 * Fixed client crash if /NICK was given without arguments.
2727 Affected file lib/silcclient/command.c.
2729 * Server does not send the invite list in INVITE command back
2730 to the client if the list was not altered. Added this notion
2731 to the protocol spec as well. Affected file silcd/command.c.
2733 Fixed possible crash in INVITE command by checking the
2734 value of silc_server_get_client_route command.
2736 * Fixed the INVITE notify type handling. The arguments are now
2737 taken in correct order and client does not crash. The affected
2738 file is irssi/src/silc/core/silc-channels.c.
2740 Removed the "Inviting xxx to channel" message from the
2741 client library away and let the application handle it.
2742 Affected file lib/silcclient/command.c. Added that message
2743 to Irssi SILC client's message formats.
2745 * Fixed CMODE command crash in client. It now checks the
2746 amount of arguments correctly and does not crash. The affected
2747 file is lib/silcclient/command.c.
2749 * Do not create new channel automatically in silc_channels_join
2750 but check whether the channel by that name already exists.
2751 Affected file irssi/silc/core/silc-channels.c.
2753 * Do not send the SERVER_SIGNOFF to router if the disconnected
2754 entity was the router. Affected file silcd/server.c.
2756 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2757 SILC client as it was missing from there.
2759 Added the handling of the KICK notify to the Irssi SILC client
2760 as it was missing. Added "you have been kicked" message to
2761 Irssi SILC client's message modules formats.
2763 Added the handing of the KILL notify to the Irssi SILC client
2764 as it was missing. Added the kill message module formats
2767 The affected file is irssi/src/silc/core/silc-channels.c.
2769 * The router did not save the channel mode the server announced.
2770 Affected file silcd/packet_receive.c.
2772 * Fixed a possible crash in INFO command in server. If the
2773 server did not provide the server info it crashed. Affected
2774 file silcd/command.c.
2776 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Fixed the GETKEY command in the server to check also the
2779 global list. Otherwise the GETKEY would not work correctly
2780 in normal SILC server. Affected file silcd/command.c.
2782 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Fixed GETKEY crash, it crashed if the command did not succseed.
2786 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2789 is now real and not just an macro interface to GMP.
2791 Removed the entire GMP from the source tree and imported new
2792 NSS MPI library instead. Reason for removing GMP is that it is
2793 extremely large and compiles extremely slow. The NSS MPI
2794 is only a few files and compiles in less than 10 seconds.
2795 The speed is also about the same as GMP. The MPI is imported
2796 to lib/silcmath/mpi.
2798 If the system has GMP installed we will still use the GMP.
2799 If it is not then the NSS MPI will be compiled.
2801 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Merged a long nickname (127 characters long) crash bugfix from
2804 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2806 * Merged a freed memory reference bugfix from Irssi CVS tree.
2807 Affected file irssi/src/core/commands.c.
2809 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2811 * Added the server's public key sving and verification to the
2812 server when performing the SKE. This was missing and the
2813 remote server's (or router's) public key was accepted without
2814 checking whether we have it previously or trust it at all.
2815 Affected file silcd/protocol.c.
2817 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2819 * Check in the silc_server_timeout_remote if protocol is active
2820 and make sure that the protocol's final callback is called so
2821 that all memory if freed. Affected file silcd/server.c.
2823 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * silc_server_whois_send_reply crashed the server if the nickname
2826 was 127 characters long. Affected file silcd/command.c.
2828 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Added sanity check to the silc_server_new_client. If the hostname
2831 is provided inside username then check that the provided hostname
2832 really is the same as the resolved one. If the hostname was not
2833 resolved then check it from the public key. Affected file is
2834 silcd/packet_receive.c.
2836 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2837 if the server disconnected us and the connection is not valid
2838 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2840 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2841 the library to the lib/silcutil/silcutil.[ch].
2843 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2845 * Close log file after open. Affected file
2846 lib/silcutil/silclog.c.
2848 * Check whether sock == NULL in silc_client_send_packet and return
2849 if it is. Affected file lib/silcclient/silcclient.c.
2851 * Check rec->entry == NULL in the Irssi SILC Client before
2852 sending the channel message. Affecte file is
2853 irssi/src/silc/core/silc-servers.c.
2855 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Merged a splitted window bugfix from Irssi CVS tree. The
2858 affected file is irssi/src/fe-text/textbuffer-view.c.
2860 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2861 It did not print nickname.
2863 * Improved the distributions system a bit.
2865 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2867 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2868 irssi/src/fe-text/gui-window.c.
2870 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2871 to in-active server. The affected file is
2872 irssi/src/silc/core/client_ops.c.
2874 * Resolve the client in USERS command reply if the entry does
2875 not have username resolved. The affected file is
2876 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2877 command to WHOIS command to really resolve stuff. The USERS
2878 is not used any more in any critical section so WHOIS can
2879 be used even though it might be slower than IDENTIFY.
2881 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2884 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Changed the protocol API a bit more consistent in the
2887 lib/silccore/silcprotocol.[ch].
2889 * Changed the following headers to ROBODoc format:
2891 lib/silccore/silcpayload.h
2892 lib/silccore/silcprotocol.h
2893 lib/silccore/silcsockconn.h
2895 All core library headers are now formatted.
2897 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Fixed a bug in Irssi SILC client; do not show that you are
2900 server/router operator if you really are not. Affected file is
2901 irssi/src/silc/core/client_ops.c.
2903 * Renamed silc_command_free_payload to silc_command_payload_free.
2904 Affected file lib/silccore/silccommand.h
2906 * Added silcmath.h to include the prototoypes of various routines
2907 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2910 * Changed the following headers to ROBODoc format:
2912 lib/silccore/silcchannel.h
2913 lib/silccore/silccommand.h
2914 lib/silccore/silcid.h
2915 lib/silccore/silcidcache.h
2916 lib/silccore/silcmode.h
2917 lib/silccore/silcnotify.h
2918 lib/silccore/silcpacket.h
2919 lib/silcmath/silcmath.h
2921 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Added checking to the server code not to start the server if
2924 ciphers and stuff are not configured properly. Affected files
2925 silcd/serverconfig.[h] and silcd/server.c.
2927 * Changed the layout of the header files of the public interfaces
2928 in the SILC libraries. The new layout supports ROBODoc
2929 documentation tool (and some others) so that it is easy to create
2930 a library reference manual. All the other headers and source
2931 code must still follow the CodingStyle document. Also source
2932 code must not include these ROBODoc stuffs, only the headers.
2933 Furthermore, all public interface headers must now be named
2934 by using `silc' prefix, example: silcapi.h, silccipher.h.
2935 Some files were renamed due to this. All the other headers
2936 must not be used as public interfaces. I will update the
2937 CodingStyle document later. Changed following headers, so far:
2939 lib/silcclient/silcapi.h
2940 lib/silccore/silcauth.h
2941 lib/silccore/silcprivate.h
2942 lib/silccrypt/silcdh.h
2944 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2948 * Removed silc_client_packet_send_flush from the client library
2949 as it is not needed. Affected file lib/silcclient/client.[ch].
2951 * Added printing of message of unresolved authentication method
2952 to the Irssi SILC client. Added it to the module formats.
2953 Removed the same message from the client library.
2955 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added new distribution feature, DISTLABEL. Every distribution
2958 can define own preprocessor label that can be used in the
2959 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2960 file distributions, acconfig.h.pre and prepare.
2962 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Added Makefile.defines_int to include the actual definitions
2965 for Makefile.defines.in. Tested the new distribution system,
2966 created distributions and tested installation.
2968 * Added AWAY message printing to the Irssi SILC client. Added
2969 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2971 * Added SCONNECT command to call the SILC's CONNECT command.
2972 Cannot use CONNECT directly since Irssi uses that internally.
2973 Affected file irssi/src/silc/core/silc-servers.c.
2975 Added ACTION local command. It is same as ME command but takes
2976 the channel as mandatory argument.
2978 Rewrote some of the Irssi's help files to suite for SILC
2981 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2983 * Added Makefile.defines[.in] that should for now on be included
2984 in all Makefile.am file in the source tree. That file includes
2985 all common compilation definitions for SILC source tree.
2987 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2989 * Minor changes to the ./prepare script to change the package
2990 name according the distribution name to the configure.in.
2992 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2994 * Created new distribution system. Added file `distributions'
2995 that defines all the distributions that can be created out of
2996 the SILC source tree. The ./prepare script now reads that
2997 file to determine how to prepare the distributions. The
2998 first argument to the ./prepare is the name of the distribution
2999 and second is the version of the distribution. If given
3000 without arguments it creates the default (toolkit) distribution
3001 with the default version (defined in ./prepare).
3003 All Makefile.am files that are subject to the distributions
3004 are now named as Makefile.am.pre. These are ./Makefile.am
3005 and lib/Makefile.am. Others may be changed later.
3007 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3009 * Added invite list, ban list, some key management and connection
3010 error message printing to module formats in the Irssi SILC client.
3012 * Added new silc_client_set_away_message to set the away message
3013 that is back to the person who sent private message. The
3014 affected file lib/silcclient/silcapi.h and the
3015 lib/silcclient/client_prvmsg.c.
3017 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Fixed the private message sending in the Irssi SILC client,
3020 added local command KEY to the Irssi SILC client.
3022 Added key management and key agreement message formats to the
3023 irssi/src/fe-common/silc/module-formats.[ch].
3025 Added USERS (alias WHO) printing, server/router operator
3026 indication and LIST command printing to the module formats.
3028 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Fixed channel joining notify handling, cumode notify handling
3031 from Irssi SILC client.
3033 * Added SILC specific module-formats to the Irssi SILC client so
3034 that SILC specific message hilighting, colors etc is possible.
3035 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3037 Added channel mode, channel user mode, actions, notices,
3038 whois and whowas printing to the the module-formats.c.
3040 * Fixed a bug in channel deletion in the server. The channel
3041 is not left to the cache even if the channel founder auth mode
3042 is set when there are no users anymore on the channel. Affected
3043 file silcd/server.c.
3045 * The silc_net_localhost now resolves the entire hostname including
3046 the domain name. Affected file lib/silcutil/silcnet.c.
3048 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Changed the ask_passphrase client operation to be ascynchronous.
3051 It has now a completion callback and a context that the
3052 application must call after it has got the passphrase from
3053 the user. Affected files lib/silcclient/silcapi.h,
3054 lib/silcclient/protocol.c, lib/silcclient/command.c and
3057 Added SilcAskPassphrase callback that the application calls
3058 to deliver the passphrase to the library.
3060 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3061 The public key verification and especially a certificate
3062 verification is asynchronous procedure.
3064 Added new SILC_SKE_STATUS_PENDING status to indicate the
3065 request is pending and a callback will be called to finalize
3068 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3069 indicate that remote end did not send its public key (or
3070 certificate), even though we require it. Added check for this
3071 condition in the SKE. This was a security bug, now fixed.
3073 Defined new SilcSKEVerifyCbCompletion callback that is called
3074 when the verification process is completed.
3076 The affected files lib/silcske/silcske_status.h and
3077 lib/silcske/silcske.[ch].
3079 * Changed the verify_public_key client operation to be async
3080 as well. Defined SilcVerifyPublicKey callback that is used to
3081 indicate the success of the public key verification process.
3083 Changed the server and client to use the new async client
3086 * Changed the Irssi SILC client's internal scheduler to be called
3087 twice as many times as it used to be. As a result the client
3088 should be a bit faster now. Affected file is
3089 irssi/src/silc/core/silc-core.c.
3091 * Added support to Irssi SILC client of asynchronous public key
3092 verification and passphrase inquiry. Affected file is
3093 irssi/src/silc/core/silc-core.c.
3095 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Do not say "You have left channel %s" in client library.
3098 Moved it to the application. Affected files are
3099 lib/silcclient/command.c and silc/client_ops.c.
3101 * Fixed silc_client_get_clients. Command context was not
3102 duplicated and was freed memory in the callback. Affected
3103 file lib/silcclient/idlist.c.
3105 * Do not say "you are now talking..." on JOIN command in the
3106 client library. The appliation must handle it.
3108 * Do not say ".. changed topic to" in command reply in the
3109 client libary. The application must handle it.
3111 * Fixed TOPIC command sending in the client library.
3113 * Fixed a memory leak in silc_client_command_free in the file
3114 lib/silcclient/command.c.
3116 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Imported a modified version of Irssi client to the source tree.
3119 The Irssi will be used to create a new client called
3120 Irssi SILC. Imported to irssi/.
3122 Added silc_core_init_finish function to the Irssi. Affected
3123 file irssi/configure.in.
3125 A lot changes in the Makefile.ams around the irssi tree.
3127 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Do not rehash if the new size is same as the old size of the
3130 hash table, in the silc_hash_table_rehash*. The affected file
3131 lib/silcutil/silchashtable.c.
3133 * Replaced hash_table_del_by_context calls from the server
3134 (when channel->user_list and client->channels) to the
3135 hash_table_del as it is sufficient and faster.
3137 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Added silc_hash_table_list, silc_hash_table_get and the
3140 SilcHashTableList structure to provide an alternative way to
3141 traverse the hash table. The affected files are
3142 lib/silcutil/silchashtable.[ch].
3144 * Changed the server's idlist routines to use the hash table
3145 routines to optimize the code.
3147 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Replaced the client entry's `channel' list and channel entry's
3150 `user_list' list to hash tables for optimized lookup. Changed
3151 the code to use the hash table interface around the code.
3152 Affected file lib/silcd/idlist.[ch].
3154 * Added `auto_rehash' boolean argument to the function
3155 silc_hash_table_alloc to indicate whether the hash table should
3156 auto-rehash when it thinks is appropriate time. It will
3157 increase the hash table size if the there is twice as much
3158 entries in the table than the size of the table, and will
3159 decrease the size if there are twice as less entries than
3160 the size of the table.
3162 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3166 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * silc_idcache_purge_by_context deletes the entry now by context
3169 as it is supposed to do. Affected file lib/silccore/idcache.c.
3171 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3172 client is not anymore valid (WHOWAS givens the info) and not
3173 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3175 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Removed the `data' and `data_len' arguments from the ID Cache
3178 interfaces and added `name' argument. ID Cache does not handle
3179 anymore the binary data only a names associated with given ID.
3181 * When hashing a Client ID with silc_hash_id the entire ID is
3182 not hashed anymore, instead only the hash of the Client ID is
3183 hashed. This way we can access the Client ID from the cache
3184 with Client ID but with the hash of the ID (which is a hash of
3185 the nickname) as well without any difference in performance.
3187 Added also silc_idcache_find_by_id_one_ext to do one on one
3188 searching when we have the actual ID. Added also function
3189 silc_hash_client_id_compare. The affected files are
3190 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3192 * When hashing the name associated with a ID it is always done
3193 in lowercase. This way we can access the cache without worrying
3194 about case-sensitivity, even though, for example nicknames are
3197 * Fixed a bug in server with channel message sending. It put
3198 wrong ID type as destination ID. The affected file
3199 silcd/packet_send.c.
3201 * silc_idcache_del_by_context now deletes from all hash tables
3202 by context. Affected file lib/silccore/idcache.c.
3204 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Changed the client library to use the new ID Cache interface.
3207 Changes around the source tree.
3209 * Added silc_hash_table_rehash_ext to rehash with specific
3210 hash function. Affected file lib/silcutil/silchashtable.[ch].
3212 * Added silc_hash_string_compare to compare two strings in the
3213 hash table. Affected file lib/silcutil/silcutil.[ch].
3215 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Added new function silc_idcache_del_by_context into the
3218 lib/silccore/idcache.[ch].
3220 * Changed the server's ID list routines to use the new ID Cache
3221 interface. Changes around the source tree.
3223 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Added silc_hash_table_del[_by_context]_ext functions in to the
3226 lib/silcutil/silchashtable.[ch].
3228 Removed silc_hash_table_find_all* routines and added new
3229 silc_hash_table_find_foreach to replace them.
3231 Added silc_hash_table_replace_ext function as extended
3232 replacing function. Separated the simple hash table interface
3233 from the extended hash table interface in the file
3234 lib/silcutil/silchashtable.h.
3236 * Fixed minor bugs and changed it to use some of the new
3237 hash table functions in lib/silccore/idcache.c
3239 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3241 * Added new function silc_hash_table_find_all to return all keys
3242 in the hash table by the specified key. As the hash table is
3243 collision resistant it also makes it possible to have several
3244 duplicate keys in the hash table. This function may be used to
3245 find all of the keys from the hash.
3247 Added user_context arguments to the SilcHashFunction,
3248 SilcHashCompare and SilcHashDestructor to deliver user specified
3251 Added new fuctions silc_hash_table_find[_all]_ext to do
3252 extended lookup with specified hash and compare functions and
3253 specified user contexts.
3255 Added new function silc_hash_table_add_ext to add the key
3256 with specified hash function and user context.
3258 Added new function silc_hash_table_foreach to traverse all
3259 entrys in the hash table. Added SilcHashForeach callback
3262 Added new function silc_hash_table_del_by_context to delete
3263 the entry only if the context associated with the key matches.
3265 Affected files are lib/silcutil/silchashtable.[ch].
3267 * Removed silc_hash_[server/client/channel]_id and added just
3268 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3269 silc_hash_id_compare to compare two ID's using as the hash table
3270 comparison function. Added also silc_hash_data to hash
3271 binary data and silc_hash_data_compare to compare it.
3273 * Removed silc_idlist_find_client_by_hash as it is not needed
3274 anymore. Affected file silcd/idlist.[ch].
3276 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3277 to use internally the SilcHashTable. The new ID Cache is a lot
3278 faster than the old one. Some of the ID Cache interface was also
3279 rewritten and obsolete and stupid functions were removed.
3281 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Added entry_count field to the SilcHashTable to keep the number
3284 of the entries in the table. Implemented the function
3285 silc_hash_table_rehash. Added new function
3286 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3288 Fixed a minor bug in silc_hash_table_free.
3290 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3291 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3292 into the lib/silcutil/silcutil.[ch].
3294 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Implemented a collision resistant hash table into the
3297 lib/silcutil/silchashtable[ch]. See the header and the source
3298 for the SilcHashTable API.
3300 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Merged dotconf version 1.0.2 into lib/dotconf.
3304 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Do not compile anything in lib/silcsim/* if the SIM support
3307 is not enabled. The tree should now compile without problems
3310 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Compiled the SILC under cygwin. Compiled and tested briefly
3313 without problems. More tests needed. The SIMs didn't compile
3316 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3318 * Fixed possible crash in silc_get_username in the
3319 lib/silcutil/silcutil.c.
3321 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Fixed a va_arg in silc/client_ops.c.
3325 * Oops, RC5 routines were named AES and caused some problems
3326 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3328 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Added new SilcIDIP structure into the lib/silccore/id.h and
3331 replaced the old `ip' fields from all SILC ID's to that type.
3332 This is a step towards IPv6 support.
3334 The silc_id_get_len takes now the ID as an extra argument.
3335 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3336 both IPv4 and IPv6 based ID's.
3338 The affected files are lib/silccore/id.[ch] and other files
3339 around the tree using these routines.
3341 * Removed the ID length arguments in server from various
3342 silc_server_send_notify_* routines -> they are not needed
3345 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Fixed memory leak in silc_encode_pem_file in the file
3348 lib/silcutil/silcutil.c.
3350 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * Check minor version as well in the SKE. Affected files are
3353 silcd/protocol.c and lib/silcclient/protocol.c.
3355 * Added --identifier option to the server so that an identifier
3356 can be when creating the public key for the server. Affected
3357 file is silcd/silcd.c.
3359 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3360 lib/silccrypt/silcpkcs.c.
3362 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Register default ciphers and stuff when using -C option with
3365 the server. Affected file sildc/silcd.c.
3367 * Put back the servers public key filename format, it is better
3368 than the new one. For now, the client keys are saved with the
3369 new filename format. The affected file silc/client_ops.c.
3371 * Implemented the Cipher API for the rest of the ciphers that
3372 did not implement it or implemented it the wrong way.
3374 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Register default ciphers and stuff when using the -S option
3377 in the client. Affected file silc/silc.c. Same also when
3378 creating new key pair with -C option.
3380 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Fixed the silc_verify_public_key client operation function to
3383 save the public keys differently. The fingerprint is now
3384 used as filename and not the hostname. This way also the
3385 client keys are saved uniquely and not with hostnames. The
3386 affected file is silc/client_ops.c.
3388 * Trimmed the silc_hash_fingerprint function to remove extra
3389 whitespaces from the end of the fingerprint. The affected
3390 file is lib/silccrypt/silchash.c.
3394 * Added silc_cipher_register_default function to register all
3395 default ciphers. It can be used when configuration files
3396 does not exist and the application does not want any specific
3397 ciphers in any specific order.
3399 The SilcDList is now used as silc_cipher_list dynamically
3400 allocated cipher list. Removed the static list all together
3401 and now all ciphers must be allocated to the dynamic list.
3402 The silc_cipher_alloc routine was changed to check only the
3405 All silc_cipher_* routines that used to return int returns
3408 The affected files lib/silccrypt/silccrypt.[ch].
3410 * The same thing was done to silc_hash_* as for silc_cipher_*
3411 routines. Affected files lib/silccrypt/silchash.[ch].
3413 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3414 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3415 Added also silc_pkcs_[un]register[_default] functions.
3416 Removed the data_context from the PKCS API.
3418 * Added silc_hmac_register_default function to register default
3419 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3420 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3421 to unregister all hmacs at once.
3423 * Register the default ciphers, hash functions, PKCSs and HMACs
3424 if client's configuration file does not exist. The affected
3427 * The client did not load the hash functions from the SIM
3428 modules at all. Added support for this. Affected file is
3429 silc/clientconfig.c.
3431 * When decoding public key with silc_pkcs_public_key_decode, check
3432 the supported algorithm only if PKCS are registered. Affected
3433 file lib/silccrypt/silcpkcs.c. The same was done with the
3434 silc_pkcs_private_key_decode.
3436 * Fixed the SILC List routines to keep the list always in order.
3437 It used to change the list's order when traversing the list but
3438 not it preserves the order. Affected file lib/trq/silclist.h.
3440 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Added the client library to use the SilcSocketConnection's
3443 reference counter (by silc_socket_dup) to prevent the bug that
3444 the socket object may be freed underneath async operation.
3446 * The name resolv library checking fixes in the configure.in.pre.
3449 * Created new version of the protocol drafts for future
3450 development. The -03 drafts are the ones that will be changed
3451 in the trunk now and the -02 will remain as they are.
3453 * Send list of CUMODE notifys to the router when announcing
3454 the channel users to the router. Affected file silcd/server.c.
3455 If the router receiving channel founder CUMODE for a channel
3456 that already has channel founder it will send CUMODE notify
3457 to the sender to remove the channel founder rights from the
3458 announced client. Affected file silcd/packet_receive.c.
3460 * The CUMODE notify may now use Server ID as well as the entity
3461 who changes the mode. Updated protocool specs.
3463 * Updated INSTALL and README files.
3465 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * New web pages in the http://silc.pspt.fi. The pages was
3472 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Implemented the [DenyConnectin] config section in the server.
3475 Added silc_server_config_denied_conn to check whether incoming
3476 connection is denied. Affected file silcd/serverconfig.[ch].
3478 * Do not check the ports when checking the incoming configuration
3479 data if the port is 0, meaning any. Affected file is
3480 silcd/serverconfig.c.
3482 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Fixed buffer overflow in silc_string_compare in the file
3485 lib/silcutil/silcutil.c.
3487 * Fixed double free in silc_server_command_leave in the file
3490 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Fixed the version checking in the server. Affected file is
3495 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Fixed the configuration data fetching when accepting new
3498 connections in the server. Affected file silcd/server.c.
3500 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Added `sender_entry' argument to the function
3503 silc_server_packet_relay_to_channel so that we can check
3504 whether some destination actually belongs to the same route
3505 the sender belongs (ie, we must not resend the packet to the
3506 sender). Affected file silcd/packet_send.[ch].
3508 * Added `servername' field to the SilcClientEntry in the server
3509 to hold the name of the server where client is from. Affected
3510 file is silcd/idlist.h.
3512 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Moved the channel message encrypting in the router betwen
3515 router connections from silc_server_channel_message to the
3516 silc_server_packet_relay_to_channel since we want to check
3517 whether we have anybody channel before encrypting anything.
3518 Affected files silcd/packet_[receive/send].c.
3520 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Fixed the [AdminConnection] server config section to support
3523 multiple entries. Affected file silcd/serverconfig.c.
3525 * Added support into the server to check the validity of the
3526 incoming connection before executing any KE or authentication
3529 * The connection configuration is now saved to the KE and
3530 connection auth protocol contexts and not fetched anymore in
3531 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3533 * The local hosts listenning address and port is also resolved
3534 now when starting the server. We want to have the socket object
3535 to include the real address and port for the listener. Added
3536 new function silc_net_check_local_by_sock into the files
3537 lib/silcutil/silcnet.[ch].
3539 * Fixed a broadcast bug in server -> do not broadcast if we
3542 * Fixed a routing bug. Do not route broadcast packets ever.
3543 Broadcast packets must be processed always and not routed since
3544 they may be destined to some other host than yourself and thus
3545 would get routed without no good reason. Affected file is
3548 * Added function silc_server_config_is_primary_route to check
3549 whether primary router connection has been configured (a router
3550 configuration that we are initiating). If there is not, we
3551 will assume that there is only two routers in the SILC network
3552 and we will use the incoming router connection as our primary
3553 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3555 * Changed the order of the broadcasting. Broadcast _after_ the
3556 packet has been processed not before. Affected file is
3559 * Fixed a [ClientConnection] parsing bug. The port was never
3560 parsed correctly thus resulting to port 0. Affected file
3561 silcd/serverconfig.c.
3563 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3564 argument and did not set the broadcast packet flag. Affected
3565 file silcd/packet_send.c. Fixed same bug in the function
3566 silc_server_send_notify as well.
3568 * If we receive NEW_ID packet for our own ID in the server, ignore
3571 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3575 * Removed the nickname from the Private Message Payload.
3576 Updated the code and the protocol specs.
3578 * Updated protocol specs for submitting to the IETF.
3580 * Tweaked the Random Number Generator a bit. Affected file
3581 lib/silccrypt/silcrng.c. Exported a new function
3582 silc_rng_[global]_add_noise which can be used to add more
3585 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Do not parse packets with different timeout when protocol
3588 is active -> may cause problem with rekey. Affected file
3591 * When server receives signoff notify it must not create
3592 new channel key if the client is on any channels since the
3593 sender of the signoff notify will create it.
3595 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3597 * Added printing of error messages during SKE protocol from the
3598 failure packet sent by server during SKE. Affected file
3601 * Removed the client's failure_callback handling with timeout
3602 and handle it immediately when received.
3604 * The SKE library returned wrong type in SUCCESS and FAILURE
3605 packets. They must be 32 bit MSB not 16 bit MSB.
3607 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Ok, rewrote the logic of the re-key and now it seems to work.
3610 I tested it on high traffic with frequent re-keys without
3611 problems. Added hmac_receive (and renamed hmac to hmac_send)
3612 in SilcClientConnection in lib/silcclient/client.h and
3613 in SilcIDListData in silcd/idlist.h. Also, removed the
3614 SilcPacketParserContext's cipher and hmac fields as they are
3615 not needed anymore and actually caused some problems when
3616 the ciphers and hmac's changed underneath the packet parser.
3618 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3620 * If re-key protocol is active then process the incoming packets
3621 synchronously since we must assure that icoming packets encrypted
3622 with the old key is processed before the new keys is set to
3623 use. This is true other packets than for REKEY packets.
3624 Affected file silcd/server.c. The same was done to client library
3625 as well, affected file lib/silcclient/client.c.
3627 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Fixed bug in client and server to accept the force send if
3630 the packet is send from silc_[server/client]_packet_process
3631 function. Otherwise the packets are never delivered, oops.
3633 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Disable force sending of packets when REKEY protocol is active.
3636 We must assure that no packet is sent directly when rekey is
3637 performed. All packets must be sent through packet queue.
3638 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3639 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3640 function is silc_[server/client]_packet_send_real to check
3643 * Replaced the SIM paths from example config files to
3644 /usr/local/modules. Also, make install creates now
3645 /usr/local/silc/logs directory to hold all the SILC server
3648 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Made the configure.in.pre work on Solaris. Patch by salo.
3652 * Made all ciphers compatible with non-x86 machines. Defined
3653 CBC mode macros into lib/silccrypt/ciphers_def.h.
3655 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Fixed the make install.
3659 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * When MAC computation fails the silc_packet_decrypt returned 0
3662 even though it was supposed to return -1. Fixed this. The
3663 affected file is lib/silccore/silcpacket.c.
3665 * Do not replace the config files in /etc/silc (in make install)
3666 if they already exist. Affected file ./Makefile.am.
3668 * Do not send re-key packets immediately but through packet queue.
3669 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3671 * Changed silc_net_check_host_by_sock to return FALSE if the
3672 IP/DNS could not be resolved. Though, it returns the IP address
3673 now even if it could not resolve it (but returns also FALSE).
3674 Affected file lib/silcutil/silcnet.[ch].
3676 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Added silc_pkcs_decode_identifier to decode the public key's
3679 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3680 Added also silc_pkcs_free_identifier. Added also new context
3681 SilcPublicKeyIdentifier.
3683 * Added -S option to the silc client. It is used to dump the
3684 contents of the specified public key file.
3686 * Changed the PKCS api to return the public key length when
3687 setting the public key.
3689 * Fixed a fatal bug in the public and private key file loading.
3690 Affected file lib/silccrypt/silcpkcs.c.
3692 * Execute the packet parsing for client with zero (0) timeout
3693 if the protocol is active. Affected file silcd/server.c.
3695 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Made the key generation options to the silcd program. Added
3698 -C option, equivalent to client's option.
3700 * Added new [ServerKeys] config section to the server. It
3701 configures the server's public and private key.
3703 * Defined generic Public Key Payload into the protocol
3704 specification to send specific type of public keys and
3707 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3708 public key or certificate.
3710 * Implemented the GETKEY command to the server and to the
3711 client library and on user interface.
3713 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Made preliminary `make install' work.
3717 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Added SilcServerRekey context into silcd/idlist.h.
3721 * Added the PFS support as defined in the specification to the
3722 SKE protocol. Affected files lib/silcske/*.c.
3724 * Added `ske_group' field to the SilcServerRekey context to hold
3725 the number of the SKE group that is used with PFS in re-key.
3726 Affected file silcd/idlist.h.
3728 * Added PFS re-key support to the server. Affected file is
3731 * Added silc_protocol_cancel to cancel execution of the next
3732 state of the protocol. Affected file is
3733 lib/silccore/silcprotocol.[ch].
3735 * Added the re-key support with and without PFS to the client
3736 library. Re-key is performed once in an hour, by default.
3738 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3739 Added silc_client_rekey_callback and silc_client_rekey_final.
3740 Affected files are lib/silcclient/protocol.[ch] and
3741 lib/silcclient/client.[ch].
3743 * Removed the `hmac_key' and `hmac_key_len' fields from the
3744 SilcClientConnection structure; not needed. Affected file is
3745 lib/silcclient/client.h.
3749 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Do not ask whether user wants to use the negotiated private key
3752 for private messages, just use it. Affected file is
3753 silc/local_command.c.
3755 * Added `send_enc_key' and `enc_key_len' fields to the
3756 SilcIDListData structure since they are needed in the re-key
3757 phase. Affected file is silcd/idlist.[ch].
3759 * Implemented the simple re-key protocol into the server.
3760 Affected files silcd/server.c and silcd/protocol.[ch]. The
3761 re-key will be performed once in an hour, by default.
3763 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3764 Added silc_server_rekey, silc_server_rekey_callback and
3765 silc_server_rekey_final.
3767 * Removed Tunneled flag from the protocol. Updated the code
3768 and the specifications.
3770 * Adde `pfs' field to the SilcIDListData to indicate whether
3771 the PFS is to be performed in the re-key. Affected file is
3774 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3776 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3777 int64 of at least the xintXX size. If void * is less that 4
3778 bytes uint32 * will be used. Defined bool as boolean.
3780 * Changed _ALL_ unsigned long and unsigned int to uint32,
3781 unsgined short to uint16 in the source tree.
3783 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3784 not handle clients that has entry->data.registered == FALSE.
3785 They are not in the network anymore. Affected file is
3788 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Implemented the sending of the SERVER_SIGNOFF notify in the
3791 server. Affected file is silcd/server.c.
3793 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3794 Added also silc_notify_payload_encode_args into the
3795 lib/silccore/silcnotify.[ch].
3797 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3798 Affected file silcd/packet_receive.c.
3800 * Implemented the SERVER_SIGNOFF notify handling in the client
3801 library. Affected file lib/silcclient/client_notify.c. Also,
3802 implemnted the printing of the SERVER_SIGNOFF info to the
3803 application. Affected file silc/client_ops.c.
3805 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3806 if the deleting was successful. Affected file silcd/idlist.[ch].
3808 * Added support for public key authentication in the connection
3809 authentication protocol in the client library. Affected file
3810 lib/silcclient/protocol.c.
3812 * Changed the server's silc_idlist_get_clients_by_* interface
3813 to support already allocated array so that new entries may be
3814 added to pre-allocated array. Affected file silcd/idlist.[ch].
3815 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3816 and command replies.
3818 * All command reply functions in the server now calls the
3819 pending command callback even if error occured. This way the
3820 error will be delivered to the client as well. Affected files
3821 silcd/command.c and silcd/command_reply.c.
3823 * Fixed INFO command to return local server's info if no server
3824 was provided. Affected file lib/silcclient/command.c.
3826 * Removed RESTART command for good. Updated the code and the
3829 * Rewrote parts of the task system. It is a bit simpler now.
3830 Removed unsued task priorities. The affected files are
3831 lib/silcutil/silctask.[ch].
3833 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3835 * Moved the USERS printing from the library to the application.
3836 Affected files lib/silcclient/command.c and silc/client_ops.c.
3838 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3842 * Added channel key re-key support. The re-key is perfomed
3843 only by the router and is done once in an hour. Added `rekey'
3844 field to the SilcChannelEntry in the server. Affected files
3845 silcd/server.c and silcd/idlist.h.
3847 * Added silc_task_unregister_by_context into the file
3848 lib/silcutil/silctask.[ch].
3850 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3852 * Added SILC_UMODE_GONE mode to indicate when the client is not
3853 present in the SILC network. Added also support to the local
3854 command AWAY that will set this mode. Added support of showing
3855 "xxx is gone" in WHOIS command. The USERS command shows the
3856 gone status as well.
3858 * Fixed setting server and router operator privileges in the
3859 server's UMODE command. Affected file silcd/command.c.
3861 * Merged the SKE KE1 and KE2 payloads into one payload. The
3862 new KE payload is equivalent to the old KE2 payload.
3864 Cleaned up the SKE Start Payload parsing. It now uses the
3865 simple buffer unformatting to do the parsing. A lot faster
3868 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3869 to the SKE that is used to indicate whether both of the SKE
3870 parties should perform authentication. By default only the
3871 responder performs authentication. By setting this flag also
3872 the initiator must do authentication. By default it is unset
3873 since in normal SKE case, client to server connection, only
3874 the responder should do authentication. When doing SKE between
3875 two clients both should perform authentication. Updated the
3876 code and the protocol specs.
3878 * A little fix to IDENTIFY command in the server. Search the
3879 client first by hash not nickname. Affected file is
3882 * Fixed the silc_client_close_connection to support closing
3883 the client to client connections wihtout deleting too much
3884 data. Affected file lib/silcclient/client.c.
3886 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3887 are received if protocol used to be active but is not anymore
3888 the application would crash due to NULL pointer dereference.
3889 Affected files silcd/server.c and lib/silcclient/client.c.
3891 * Added `hash' field to the SilcClientConnection to include
3892 the hash function negotiated in the SKE protocol.
3894 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3895 to set the channel founder authentication data. A client can
3896 claim the founder rights later by providing the authentication
3897 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3898 This way the channel founder can regain the channel founder
3899 privileges even it is left the channel. This works only on
3900 local server and the client must be connected to the same
3901 server to be able to regain the founder rights. Updated the
3902 protocol specs accordingly.
3904 Added support to the CMODE command in the client to set the
3905 founder auth data. Read the README to see how to set it.
3907 Added support to the CUMODE command to claim the founder
3908 rights. Read the README to see how to do it.
3910 Added support for the founder authentication to the Channel
3911 Entry in the server. Affected file silcd/idlist.h.
3913 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3914 server's CMODE command. Affected file silcd/command.c.
3916 * Added the following new functions into lib/silccore/silcauth.[ch]:
3917 silc_auth_get_method and silc_auth_get_data.
3919 * The server now saves the remote hosts public key to the
3920 SilcIDListData pointer. Affected file silcd/protocol.c.
3922 * The normal server now does not remove the channel entry from
3923 the cache if the founder authentication data is set. It used
3924 to remove it if the founder was the last one on the channel on
3925 the server and left the channel. The auth data is saved and
3926 if the channel is re-joined later the old entry is used with
3927 the old auth data. Affected files silcd/command_reply.c and
3930 * Removed the `pkcs' field from the SilcIDListData structure
3931 in the server; it is not used. Affected file silcd/idlist.h.
3933 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3935 * Fixed packet processing on slow links. Partial packets were
3936 never re-processed because the incoming data buffer was cleared
3937 by the application. Application must not directly clear the
3938 sock->inbuf, the packet processing routines handle it. Fixed
3939 this in client library and in server.
3941 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3943 * Fixed the WHOIS and IDENTIFY send reply function to really
3944 check whether to send list or just one entry. Affected file
3947 * Cleaned up the LEAVE command's channel key distribution. The
3948 affected file silcd/command.c.
3950 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3951 can enforce the channel mode as well. In that case the ID
3952 includes the ID of the server. The code now enforces the
3953 mode change if the router have different mode than the server.
3955 * The notify client operation with CMODE_CHANGE notify can now
3956 return NULL client_entry pointer if the CMODE was not changed
3957 by client. Application must check for this.
3959 * Added <Server ID> argument to INFO command to support server
3960 info fetching by Server ID.
3962 * Added silc_server_announce_get_channel_users to get assembled
3963 packets of channel users of the specified channel. Affected
3964 file silcd/server.[ch].
3966 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3967 was freed underneath the ID Cache.
3969 * Re-announce clients when the server received CHANNEL_CHANGE
3970 notify from the router. Affected file silcd/packet_send.c.
3972 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3975 crashed since it did not handle the fact that there is no cipher
3976 called "3" and didn't check the error condition. Now fixed.
3978 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3979 flag. It can be used to send message requests.
3981 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Implemented the RESTART command in the client.
3985 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3986 notice type messages. Added notice printing to the user
3989 * The channel keys are not re-generated if the channel's mode
3990 is PRIVKEY, ie private key on the channel exists. Affected
3991 files silcd/server.c and silcd/command.c.
3993 * Fixed a little bug in channel message delivery when channel
3994 private keys are set in the server. Affected file is
3995 silcd/packet_send.c.
3997 * Changed the setting on channel->on_channel = TRUE from the
3998 silc_client_save_channel_key to the JOIN command reply. The
3999 key payload is not received if the private channel key is set.
4000 Affected file lib/silcclient/command_reply.c and the
4001 lib/silcclient/client_channel.c.
4003 * When the CMODE_CHANGE notify is sent and the channel private
4004 key mode is removed the channel key must be re-generated in
4005 other cells as well. Added this support for the router in the
4006 silcd/packet_receive.c.
4008 * Added new local command NOTICE to send notice message on
4009 channel. Affected file silc/local_command.[ch].
4011 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Added new local command ME to the client. It is used to send
4014 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4015 some action. Affected file silc/local_command.[ch].
4017 * Changed channel_message and private_message client operations
4018 to deliver the message flags to the application. Added also
4019 the `flags' arguments to the silc_client_send_channel_message
4020 and silc_client_send_private_message functions. Affected file
4023 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4025 * Redefined the Private Message Payload to support private message
4026 keys and to support the new private message flags. Updated
4027 the protocol specs. Flags makes it possible to have for example
4028 CTCP style messages.
4030 * Added new type SilcPrivateMessagePayload and defined an API
4031 for it in the lib/silcclient/silcprivate.[ch].
4033 * Tested private message private keys successfully. Tested the
4034 private message key set, unset and list commands with the new
4037 * Redefined the Channel Message Payload to include the channel
4038 message flags (equal with private message flags) to support
4039 for example CTCP style messages.
4041 * Defined some of the message (for channel and private message)
4042 flags. Updated the protocol specs and added the flags to the
4043 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4045 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Added SilcKeyAgreementStatus type to the key agreement routines
4048 to indicate the current status and error if one occured.
4049 The status types are defined in the lib/silcclient/silcapi.h.
4051 * Added new local command KEY that is used to set and unset private
4052 keys for channels, set and unset private keys for private messages
4053 with remote clients and to send key agreement requests and
4054 negotiate the key agreement protocol with remote client. The
4055 key agreement is supported only to negotiate private message keys,
4056 it currently cannot be used to negotiate private keys for channels,
4057 as it is not convenient for that purpose.
4059 * Fixed a minor pending callback setting bug in the function
4060 silc_client_get_client_by_id_resolve, now the function works.
4061 Affected file lib/silcclient/idlist.c.
4063 * Added function silc_net_get_local_port to get local bound
4064 port by socket. Added to lib/silcutil/silcnet.[ch].
4066 * Added `sockets' and `sockets_count' fields to the SilcClient
4067 object. They hold the sockets of the listenning sockets in
4068 the client. Listenning sockets may be for example the key
4069 agreement server. Affected file lib/silcclient/client.[ch].
4070 Added functions the silc_client_add_socket and the
4071 silc_client_del_socket. They are exported to the application
4074 * Added ~./silc/clientkeys to support other client's public keys.
4076 * Renamed verify_server_key client operation to verify_public_key
4077 and added one argument to indicate the type of the connection
4078 (server, client etc.).
4080 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Added silc_server_connection_auth_request to handle the
4083 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4084 silcd/packet_receive.[ch].
4086 * Added silc_server_send_connection_auth_request into the
4087 silcd/packet_send.c to send the connection auth request packet.
4089 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4092 * Fixed the public key authentication in responder side in the
4093 server. The `auth_data' pointer includes the SilcPublicKey
4094 not the path to the public key. Affected file silcd/protocol.c.
4096 * Implemented the public key authentication in the initiator side
4097 in the server. Affected file silcd/protocol.c.
4099 * Removed the [RedirectClient] config section from the server
4100 configuration. Is not needed and I don't want to implement it.
4102 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Cleaned up the CMODE command in the server. It now works
4105 correctly and supports all the modes defined in the protocol.
4106 Affected file is silcd/command.c.
4108 * Added `hmac_name' field to the SilcChannelEntry in the server
4109 to hold the default HMAC of the channel. It can be set when
4110 creating the channel (with JOIN command). Affected files
4113 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4114 type to indicate the change of the current cipher and hmac
4115 on the channel. Client can safely ignore the <cipher> argument
4116 (if it chooses to do so) since the CHANNEL_KEY packet will
4117 force the channel key change anyway. The <hmac> argument is
4118 important since the client is responsible of setting the new
4119 HMAC and the hmac key into use.
4121 * Fixed the CMODE command in the client library as well.
4123 * Tested CMODE command in router environment successfully.
4125 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Show the version of the remote client (or server) when connecting
4128 to the server. It is logged to the log file. Affected file
4129 is silcd/protocol.c.
4131 * Fixed the KILLED notify handling in the client library. The
4132 client must be removed from all channels when receiving the
4135 Also, do not remove the client entry when giving the KILL
4136 command but when the KILLED notify is received.
4138 * Removed silc_idlist_find_client_by_nickname from the server.
4139 Not needed anymore. Affected files silcd/idlist.[ch].
4141 * Implemented the CHANNEL_CHANGE notify type handling to the
4142 server. Affected file silcd/server.c.
4146 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Added silc_server_send_notify_invite to send the INVITE
4149 notify between routers.
4151 * Implemented the INVITE command correctly to the server.
4153 * Implemented the INVITE notify type handling in the server.
4155 * Implemented the INVITE command to the client library and on the
4158 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Added function silc_server_get_client_resolve to find the
4161 client entry by ID from all ID lists and then resolve it
4162 (using WHOIS) if it cannot be found. Affected file is
4165 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Implemented the BAN command to the client library.
4169 * The JOIN command in the server now checks the invite list
4172 * Changed the silc_command_reply_payload_encode_va and the
4173 silc_command_payload_encode_va to support that if argument is
4174 NULL it ignores and checks the next argument. Affected file
4175 lib/silccore/silccommand.c.
4177 * Added silc_server_send_notify_ban to send the BAN notify
4178 type between routers.
4180 * Chaned the silc_notify_payload_encode to support that if
4181 argument is NULL it ignores and checks the next argument.
4182 Affected file lib/silccore/silcnotify.c.
4184 * Tested ban lists in router environment successfully.
4186 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Implemented BAN command to the server, in silcd/command.[ch].
4190 * Removed the BAN and INVITE_LIST modes from the CMODE command
4193 * Added function silc_string_match to regex match two strings.
4194 Affected files lib/silcutil/silcutil.[ch].
4196 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Redefined parts of the SilcChannelEntry in the server to support
4199 the new ban and invite lists.
4201 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Redefined the INVITE command. The same command can be used to
4204 invite individuals to the channel but also to manage the invite
4205 list of the channel (to add to and remove from the invite list).
4206 Updated the protocol specs.
4208 * Added new command SILC_COMMAND_BAN that can be used to manage
4209 the ban list of the channel. Updated the protocol specs.
4211 * Removed the channel modes: the SILC_CMODE_BAN and the
4212 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4213 in the CMODE command. The equivalent features are now available
4214 using INVITE and BAN commands. Updated the protocol specs.
4216 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4217 in the network about change in the current ban list. The notify
4218 type is not used by the client.
4220 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4221 support the invite lists.
4223 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4225 * Added new function silc_string_regexify that converts string
4226 including wildcard characters into regex string that can
4227 be used by the GNU regex library. Added into the file
4228 lib/silcutil/silcutil.[ch].
4230 Added silc_string_regex_combine to combine to regex strings
4231 into one so that they can be used as one regex string by
4232 the GNU regex library. Added into the file
4233 lib/silcutil/silcutil.[ch].
4235 Added silc_string_regex_match to match two strings. It returns
4236 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4238 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * Imported GNU regex to the soruce tree into lib/contrib.
4241 Fixed some compiler warning from the regex.c.
4243 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Fixed MOTD command in the server to work in router environment.
4247 * Fixed the MOTD command in the client library to support
4248 the server argument in the command.
4250 * Added `nickname_len' argument to the silc_idlist_add_client
4251 in the server, as the `nickname' argument may be binary data
4254 * Added silc_idlist_get_channels to return all channels from
4257 * Implemented LIST command to the server. Affected file is
4260 * Implemented the LIST command to the client library and on the
4263 * Added [<user count>] argument to the LIST command reply.
4264 With private channels the user count is not shown.
4266 * Updated TODO and README.
4268 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * The client entry's data.registered must be TRUE even with
4271 global client entry on global client list. The data.registered
4272 is used to check whether the client is anymore in the network,
4273 for example with WHOWAS command so it must be valid.
4275 * Fixed the WHOWAS command in the server. It now actually works
4276 in router environment. Added function into silcd/command_reply.c
4277 silc_server_command_reply_whowas_save.
4279 * Added silc_idlist_purge function to the silcd/idlist.c
4280 to periodically purge the ID Cache.
4282 * Fixed INFO command in the server. It works now in router
4283 environment. Added <server name> argument to the INFO command
4284 reply. Updated the protocol specs.
4286 * Fixed minor bug in silc_idcache_purge to not purge if the
4287 expire value is zero.
4289 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4290 they were buggy because of the WHOWAS information.
4292 * Fixed local command MSG to handle the async resolving of
4293 the remote client properly. It used to fail the first MSG.
4294 Affected file silc/local_command.c.
4296 * Added `data_len' field to SilcIDCache context.
4298 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Update TODO. Todo in commands in the server.
4302 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4305 used by routers as broadcast packet to inform other routers
4306 about the changed user mode.
4308 Implemented the notify handling in the server. Affected file is
4309 silcd/packet_receive.c. Added the function
4310 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4312 * Added new generic Channel Payload and deprecated the New Channel
4313 Payload. The New Channel Payload is now the generic Channel
4316 * Added new argument `mode' to the silc_server_send_new_channel
4317 as it is required in the Channel Payload now.
4319 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4320 and created a new and real SilChannelPayload to represent the
4321 new generic Channel Payload. Implemented the encode/decode
4322 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4324 * Added silc_server_get_client_channel_list to return the list
4325 of channels the client has joined for WHOIS command reply.
4326 Affected file silcd/server.[ch].
4328 * Implemented the channel list sending in the WHOIS command reply
4329 in server and in the client.
4331 Implemented the channel list displaying on the user interface
4332 as well. Affected file silc/client_ops.c.
4334 * Added silc_channel_payload_parse_list to parse list of Channel
4335 Payloads. It returns SilcDList list of SilcChannelPayloads.
4336 Client for example can use this function to parse the list of
4337 channels it receives in the WHOIS command reply. The caller
4338 must free the list by calling silc_channel_payload_list_free.
4339 Affected files lib/silccore/silcchannel.[ch].
4341 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Added one new argument <user mode> to the WHOIS command reply
4344 to return the mode of the user in SILC. Updated the protocol
4347 Implemented it to the server and client.
4349 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Fixed the mode printing on the user interface on joining.
4352 Affected file silc/client_ops.c.
4354 * Implemented the UMODE command and user modes in general to the
4355 client library and to the user interface.
4357 * Implemented the UMODE command to the server.
4359 * The server now sends UNKNOWN_COMMAND error status if client sends
4360 unknown command. Affected file silcd/command.c.
4362 * All server commands now handle the command identifier the right
4363 way when sending the command reply to the client. The client can
4364 use to identify the command replies with the identifier.
4366 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Added silc_server_get_client_route to resolve the route to
4369 the client indicated by the client ID. Affected file is
4372 * Added silc_server_relay_packet as general function to relay
4373 packet to arbitrary destination. This deprecates functions
4374 like _send_private_message_key, _relay_notify etc. Affected
4375 file is silcd/packet_send.[ch].
4377 Removed silc_server_send_key_agreement,
4378 silc_server_send_private_message_key and
4379 silc_server_packet_relay_notify functions from the file
4380 silcd/packet_send.[ch].
4384 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4385 server. Affected file silcd/packet_receive.[ch].
4387 * Implemented the KILL command to the client. Implemented the
4388 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4389 Affected files lib/silcclient/command[_reply].c and
4390 lib/silcclient/client_notify.c. Implemented the KILL notify
4391 printing in the user inteface.
4393 * Fixed a lot silc_parse_nick memory leaks from the client
4394 library in the file lib/silcclient/command.c.
4396 * Changed the silc_server_send_notify_on_channels's `sender'
4397 argument from SilcSocketConnection to SilcClientEntry to
4398 check the sender as entry and not as connection object and not
4399 to send to the client provided as argument. The affected file
4400 is silcd/packet_send.[ch].
4402 * The notify packets that are destined directly to the client used
4403 to not to be processed by the server. Now changed that and the
4404 server processes all notify packets. After relaying the packet
4405 to the client the notify packet is processed in the server.
4407 * The silc_server_free_client_data now checks whether there is
4408 pending outgoing traffic for the client and purges the data to
4409 the network before removing the client entry.
4411 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4414 an client is killed from the SILC Network. Updated the protocol
4417 Added new function silc_server_send_notify_killed to the
4418 silcd/packet_send.[ch].
4420 * Added function silc_server_packet_relay_notify to relay notify
4421 packets that are destined directly to a client. In this case
4422 the server does not process the notify packets but merely relays
4423 it to the client. Affected file silcd/packet_send.[ch].
4425 Added also silc_server_packet_process_relay_notify to check
4426 whereto relay the notify. Affected file is
4427 silcd/packet_receive.[ch].
4429 * Implemented the KILL command to the server.
4433 * Added the backup schema desgined last fall to the protocol
4434 specs for everyone to see. The specification is in the
4435 *-spec-xx.txt draft and the packet type definitions for the
4436 backup routers is in *-pp-xx.txt draft. Thusly, added also
4437 new packet type SILC_PACKET_CELL_ROUTERS.
4439 * A big security problem in the implementation discovered. The
4440 signoff of an client did not cause new channel key generation
4441 which it of course should've done. The channel keys must be
4442 always re-generated when client leaves (or signoffs) the channel.
4443 The silc_server_remove_from_channels funtion now handles
4444 the channel key re-generation.
4446 * Added `sender' argument to the silc_server_send_notify_on_channels
4447 to not to send the client provided as argument. Affected file
4448 silcd/packet_send.[ch].
4450 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Implemented OPER and SILCOPER commands into the server and
4455 * Added silc_auth_verify and silc_auth_verify_data to verify
4456 the authentication directly from the authentication payload.
4457 It supports verifying both passphrase and public key based
4458 authentication. Affected file lib/silccore/silcauth.[ch].
4460 * Added `hash' field to the SilcIDListData structure. It is the
4461 hash negotiated in the SKE protocol. Affected file is
4464 * Slight redesigning of the SilcAuthPayload handling routines.
4465 Do not send SilcPKCS but SilcPublicKey as argument.
4467 * Implemented the public key authentication support to the
4468 serverconfig. The public key is loaded from the provided path
4469 and saved as authentication data to void * pointer. Thus,
4470 changed the unsigned char *auth_data to void *auth_data;
4472 * Fixed SHUTDOWN command to send the reply before the server
4473 is shutdown. :) Affected file silcd/command.c.
4475 * Fixed fatal bug in CONNECT command. The hostname was invalid
4476 memory and server crashed. Affected file silcd/command.c.
4478 * Fixed fatal bug in CLOSE command. The server_entry became
4479 invalid but was referenced later in the command. Affected file
4482 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Fixed fatal bug in failure packet handling. Server ignored
4485 the failure and thus crashed when it came.
4489 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4492 that the command may be executed only once in (about) 2 seconds.
4493 The old SILC_CF_LAG flag is same but allows command bursts up
4494 to five before limiting.
4496 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4497 server code. Various commands now includes the CF_LAG_STRICT
4498 flag to disallow any kind of miss-use of the command.
4500 * Fixed the silc_buffer_unformat to not to allocate any data
4501 if the length of the data is zero. It used to allocate the
4502 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4504 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4506 * Changed the format of AdminConnection configuration section
4507 in the server. Added username of the admin to the format.
4508 Affected files silcd/serverconfig.[ch].
4510 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4511 to return admin configuration data by host, username and/or
4514 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Implemented WHOWAS command to the server. Added the functions:
4518 silc_server_command_whowas_parse,
4519 silc_server_command_whowas_send_reply,
4520 silc_server_command_whowas_from_client and
4521 silc_server_command_whowas_from_server
4523 * Added <Client ID> argument to the WHOWAS command reply. Updated
4524 the protocol specs accordingly.
4526 * Implemented WHOWAS command and command_reply to the client
4529 Implemented the WHOWAS printing on the user interface.
4531 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added new argument to the WHOWAS command reply, the real name.
4534 It is an optional argument. Updated the protocol specs.
4536 * Added SilcIDCacheDestructor callback that is registered when
4537 the SilcIDCache is allocated. The callback is called when
4538 an cache entry in the ID Cache expires, or is purged from the
4539 cache. Added into lib/silccore/idcache.[ch].
4541 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4542 to destruct the client entries when the cache entry expires.
4543 Other ID Cache's in server and in the client library ignores
4546 * If the ID Cache entry's `expire' field is zero then the entry
4547 never expires. Added boolean `expire' argument to the
4548 silc_idcache_add function in the lib/silccore/idcache.[ch].
4549 If it is TRUE the default expiry value is used.
4551 * Added silc_server_free_client_data_timeout that is registered
4552 when client disconnects. By default for 5 minutes we preserve
4553 the client entry for history - for WHOWAS command.
4555 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Added support to the server to enforce that commands are not
4558 executed more than once in 2 seconds. If server receives
4559 commands from client more frequently, timeout is registered
4560 to process the commands. Affected file silcd/command.c.
4561 Added new function silc_server_command_process_timeout.
4563 * Changed NICK_NOTIFY handling in client library to check that
4564 if the client's nickname was changed, so there is no need to
4565 resolve anything from the server.
4567 * Removed error printing from the WHOIS and IDENTIFY commands.
4568 If error occurs then it is ignored silently in the client library.
4569 The application, however, may map the received error to
4570 human readable error string. The application currently maps
4571 the NO_SUCH_NICKNAME error to string.
4573 * Made the command status message public to the application. Moved
4574 them from lib/silcclient/command_reply.c to
4575 lib/silcclient/command_reply.h. The application can map the
4576 received command status to the string with the
4577 silc_client_command_status_message function.
4579 * Added check to the server to check that client's ID is same
4580 as the Source ID in the packet the client sent. They must
4583 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added dist-bzip hook to the Makefile.am to make bzip2
4586 compressed distributions.
4588 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Server now enforces the maximum length for the nickname and
4591 the channel as protocol specification dictates. 128 bytes for
4592 nickname and 256 bytes for channel name.
4594 * Moved the WHOIS printing to the application. The client libary
4595 does not print out the WHOIS information anymore, the application
4596 must do it. Renamed silc_client_command_reply_whois_print to
4597 the silc_client_command_reply_whois_save.
4599 The client's idle time is also sent to the application now, and
4600 the idle is shown on screen.
4602 * Added silc_client_command_reply_identify_save to save the
4603 received IDENTIFY entries.
4605 * Do not check for channel private keys in message sending and
4606 reception if the channel does not have the PRIVKEY mode set.
4607 Affected file lib/silclient/client_channel.c.
4609 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4612 just surfaced after chaning the JOIN procedure.
4614 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * Added silc_client_get_clients_by_list to get client entries
4617 from Client ID list, that is returned for example by JOIN
4618 and USERS command replies. The application should use this
4619 function for example when JOIN command reply is received to
4620 resolve the clients already on the channel (library does not
4621 do that anymore as USERS command reply is not used in the JOIN
4622 procedure anymore). Affected files lib/silcclient/silcapi.h and
4623 lib/silcclient/idlist.c.
4625 * JOIN command reply and USERS command reply returns now SilcBuffer
4626 pointers instead of unsigned char pointers when returning
4627 the client list and mode list.
4629 * Added <Client ID> argument to the JOIN command reply, mainly
4630 for the server to identify for which client the command was
4631 originally sent. Updated protocol specs accordingly.
4633 * Added SilcDlist private_key pointer to the SilcChannelEntry
4634 in the client to support the channel private keys. Affected
4635 file is lib/silcclient/idlist.h.
4637 * Added SilcChannelPrivateKey argument to the function
4638 silc_client_send_channel_message so that application can choose
4639 to use specific private ke if it wants to. If it is not provided,
4640 the normal channel key is used, unless private keys are set.
4641 In this case the first (key that was added first) is used
4642 as the encryption key.
4644 * Implemented the support for channel private key handling.
4645 Implemented the following functions:
4647 silc_client_add_channel_private_key,
4648 silc_client_del_channel_private_keys,
4649 silc_client_del_channel_private_key,
4650 silc_client_list_channel_private_keys and
4651 silc_client_free_channel_private_keys
4653 Affected file lib/silcclient/client_channel.c.
4655 * Added the support for the private keys in the channel message
4656 sending and encryption and in the message reception and
4657 decryption. Affected funtions are
4658 silc_client_send_channel_message and silc_client_channel_message.
4660 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4662 * Added SKE's key verify callback to the client library's
4663 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4665 * Removed the statement that server (or router) must send USERS
4666 command reply when joining to the channel so that the client
4667 knows who are on the channel. Instead, the client list and
4668 client's mode list is now sent in the JOIN command reply to the
4669 client who joined channel. This is better solution.
4671 * Added function silc_server_get_users_on_channel and function
4672 silc_server_save_users_on_channel to the silcd/server.[ch].
4674 * Removed function silc_server_command_send_users from the
4677 * Do not show topic on the client library anymore. The topic is
4678 sent in the command reply notify to the application and the
4679 application must show the topic now.
4681 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added client searching by nickname hash into the IDENTIFY and
4684 WHOIS commands in the server as they were clearly missing from
4685 them. Affected file is silcd/command.c.
4687 * Fixed a bug in private message receiving in the client library.
4688 The remote ID was freed and it wasn't supposed, now it is
4691 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Minor fix to the channel payload; allocate the data area, as it
4694 needs to be of specific length.
4696 * If the key agreement port is zero then the operating
4697 system will define the bound port. Affected files are
4698 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4700 * Added new function silc_channel_payload_decrypt into the file
4701 lib/silccore/silcchannel.[ch].
4703 * Moved the channel message etc, check from silc_packet_decrypt
4704 to applications. The library calls now a generic
4705 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4706 when the packet is either normal or special. This was done to
4707 allow more wide range of checking that was not allowed when
4708 the code was in library. Now applications can do virtually any
4709 checks to the packet and return to the library the decision how
4710 the packet should be processed. Affected files are
4711 lib/silccore/silcpacket.[ch].
4713 Added silc_server_packet_decrypt_check to the server and
4714 silc_client_packet_decrypt_check to the client library.
4716 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4717 to send with specified source and destination information.
4719 * Channel message delivery between routers was broken after the
4720 channel key distribution was fixed earlier. The channel key
4721 was used be to distributed to other routers as well which is not
4722 allowed by the protocol. Now this is fixed and channel keys
4723 really are cell specific and the channel message delivery between
4724 routers comply with the protocol specification.
4726 * Fixed various commands in server to check also the global list
4727 for the channel entry and not just the local list. The affected
4728 file silcd/command.c.
4730 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Added assert()s to buffer formatting and unformatting routines
4733 to assert (if --enable-debug) when error occurs. Affected
4734 file: lib/silcutil/silcbuffmt.c.
4736 * Changed to auto-reconnect to check whether the remote host is
4737 router and register the re-connect timeout if it is. It used
4738 to check that whether we are normal server, but router must do
4739 auto-reconnect with another router as well. Affected file
4742 * Removed the [<key len>] option from CMODE command as the cipher
4743 name decides the key length, nowadays. See the defined ciphers
4744 from the protocol specification.
4746 * Added [<hmac>] option to the CMODE command to define the HMAC
4747 for the channel. Added SILC_CMODE_HMAC channel mode.
4749 * Added [<hmac>] option for the JOIN command so that user can
4750 select which HMAC is used to compute the MACs of the channel
4753 * Added Hmac field to the Channel Message Payload. The integrity
4754 of plaintext channel messages are now protected by computing
4755 MAC of the message and attaching the MAC to the payload. The
4756 MAC is encrypted. Now, it is clear that this causes some
4757 overhead to the size of the packet but rationale for this is that
4758 now the receiver can verify whether the channel message decrypted
4759 correctly and also when private keys are set for the channel the
4760 receiver can decrypt the packet with several keys and check from
4761 the MAC which key decrypted the message correctly.
4763 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4764 lib/silccrypt/silccipher.[ch].
4766 * Added silc_hash_len to return the digest length into the
4767 lib/silcrypt/silchash.[ch].
4769 * Rewrote parts of Silc Channel Payload interface in the
4770 lib/silccore/silcchannel.[ch]. The encode function now also
4771 encrypts the packet and parse function decrypts it.
4773 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * Fixed a minor formatting bug in the SKE's key material processing.
4776 It actually might have processed the keys wrong way resulting
4779 * Redefined the mandatory HMAC algorithms and added new algorithms.
4780 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4781 and hmac-md5 truncated to 96 bits. The mandatory is now
4782 hmac-sha1-96. Rest are optional (including the one that used
4783 to be mandatory). Rationale for this is that the truncated HMAC
4784 length is sufficient from security point of view and can actually
4785 make the attack against the HMAC harder. Also, the truncated
4786 HMAC causes less overhead to the packets. See the RFC2104 for
4789 * Added new [hmac] configuration section. The SKE used to use
4790 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4791 is of course wrong. The official names that must be proposed in
4792 the SKE are the ones defined in the protocol specification
4793 (hmac-sha1-96 for example). The user can configure any hmac
4794 using any hash function configured in the [hash] section. At
4795 least, the mandatory must be configured.
4797 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4799 * Added HMAC list to the SKE proposal list. It has now both
4800 hash algorithm list and HMAC list. This makes the protocol
4801 incompatible with previous versions. The SKE now seems to work
4802 the way it is supposed to work, for the first time actually.
4804 * Defined plain Hash algorithms to the protocol specification.
4807 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Implemented support for key agreement packets into the server.
4810 Added functions silc_server_key_agreement and
4811 silc_server_send_key_agreement. Other than these functions,
4812 server has nothing to do with this packet.
4814 * Added support for private message key packets into the server.
4815 Added functions silc_server_private_message_key and
4816 silc_server_send_private_message_key.
4820 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4821 called in the protocol's final callback instead in the END
4822 protocol state. This makes a little more sense and in the same
4823 time in client we can use the same protocol routines for normal
4824 key exchange and to key agreement packet handling as well.
4826 * Added to both client's and server's KE protocol context the
4827 SilcSKEKeyMaterial pointer to save the key material. We will
4828 bring the key material to the protocol's final callback by doing
4829 this. The final callback must free the key material.
4831 * Added SKE's packet_send callback into client's KE protocol
4832 context so that the caller can choose what packet sending function
4833 is used. This way we can use different packet sending when
4834 doing normal SKE when doing key agreement packet handling (in
4835 the key agreement packet handling we do not want to encrypt
4838 * Implemented the responder side of the key agreement routines
4839 in the client. The client can now bind to specified port and
4840 accept incoming key negotiation. The key material is passed
4841 to the application after the protocol is over.
4843 * Implemented the processing of incoming Key Agreement packet
4844 in the client. Added function silc_client_key_agreement to
4847 * Implemented the intiator side of the key agreement routines
4848 in the client. The client can now initiate key agreement with
4849 another remote client. The key material is passed to the
4850 application after the protocol is over.
4852 * Created client_keyagr.c to include all the key agreement
4855 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4856 SILC_TASK_CALLBACK except that it is not static.
4858 * Created client_notify.c and moved the Notify packet handling
4859 from the client.[ch] into that file.
4861 * Created client_prvmsg.c and moved all private message and
4862 private message key routines from the client.[ch] into that file.
4864 * Create client_channel.c and moved all channel message and
4865 channel private key routines from the client.[ch] into that file.
4867 * Changed silc_client_get_client_by_id_resolve to resolve with
4868 WHOIS command instead of IDENTIFY command, in the file
4869 lib/silclient/idlist.c.
4871 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4873 * Implemented the SKE's responder side to the Client library.
4875 * When FAILURE is received to the protocol do not trust it
4876 blindly. Register a timeout to wait whether the remote closes
4877 the connection as it should do it, only after that process the
4878 actual failure. This was changed to both client and server.
4880 * Added client_internal.h to include some of the structures
4881 there instead of client.h in lib/silcclient/.
4883 * Added function silc_task_unregister_by_callback to unregister
4884 timeouts by the callback function.
4886 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Some "Incomplete WHOIS info" errors has been appearing on the
4889 log files. Took away the entry->userinfo check from WHOIS
4890 reply sending. The entry->userinfo is now " " if client did not
4891 provide one. I thought this was fixed earlier but something
4892 is wrong still. Let's see if the error still appears.
4894 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Fixed a minor bug in the login when the channel key is
4897 re-generated in the server. It used to generate the key in
4898 wrong order and thus caused problems in the channel traffic.
4900 * Fixed a minor bug in channel key distsribution after
4901 KICK command. The key was not sent to the router even though
4904 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Added silc_ske_process_key_material_data as generic routine
4907 to process any key material as the SILC protocol dictates. The
4908 function is used by the actual SKE library but can be used by
4909 applications as well. This relates to the private message keys
4910 and the channel private keys since they must be processed the
4911 same way the normal SILC session keys. The protocol dictates
4912 this. Affected files: lib/silcske/silcske.[ch].
4914 Added also silc_ske_free_key_material to free the
4915 SilcSKEKeyMaterial structure.
4917 * Defined silc_cipher_set_key function to set the key for
4918 cipher without using the object's method function. The affected
4919 files: lib/silccrypt/silccipher.[ch].
4921 * Implemented silc silc_client_add_private_message_key,
4922 silc_client_add_private_message_key_ske,
4923 silc_client_del_private_message_key,
4924 silc_client_list_private_message_keys and
4925 silc_client_free_private_message_keys functions in the
4928 Added functions silc_client_send_private_message_key to send
4929 the Private Message Key payload and silc_client_private_message_key
4930 to handle incoming Private Message Key payload.
4932 * Added Cipher field to the Private Message Key payload to set
4933 the cipher to be used. If ignored, the default cipher defined
4934 in the SILC protocol (aes-256-cbc) is used.
4936 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Removed lib/silcclient/ops.h file.
4940 Redefined parts of the SILC Client Library API. Created new
4941 file silcapi.h that deprecates the ops.h file and defines the
4942 published Client Library API. Defined also private message key
4943 API and channel private key API into the file.
4945 This is the file that the application must include from the
4946 SILC Client Library. Other files need not be included by
4947 the application anymore.
4949 * Added new key_agreement client operation callback and also
4950 defined the Key Agreement library API for the application.
4952 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4955 is used by clients to request key negotiation between another
4956 client in the SILC network. If the negotiation is started it
4957 is performed using the SKE protocol. The result of the
4958 negotiation, the secret key material, can be used for example
4959 as private message key.
4961 Implemented the Key Agreement payload into the files
4962 lib/silccore/silauth.[ch].
4964 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Redefined ciphers for the SILC protocol. Added some new ciphers
4967 and defined the key lengths for the algorithms. Changed the
4968 code accordingly. The default key length is now 256 bits.
4970 * Fixed SKE key distribution function silc_ske_process_key_material
4971 when the key length is more than 128 bits. The default key
4972 length in SILC is now 256 bits.
4974 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4975 to indicate unsupported algorithm.
4977 * Renamed rijndael.c to aes.c and all functions as well.
4979 * Fixed a long standing channel key setting bug in client library.
4980 Weird that it has never surfaced before.
4982 * Fixed bug in channel deletion. If the entire channel is removed
4983 then it must also delete the references of the channel entry
4984 from the client's channel list as the client's channel entry and
4985 the channel's client entry share same memory.
4987 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Implemented CONNECT and SHUTDOWN commands in the client.
4991 * Implemented CLOSE command to the client.
4993 * Added the function silc_idlist_find_server_by_name into the
4994 files silcd/idlist.[ch].
4996 Added the function silc_idlist_find_server_by_conn into the
4997 files silcd/idlist.[ch].
4999 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * DIE command was renamed to SHUTDOWN. Updated the both code
5004 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5005 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5007 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5010 * Added function silc_server_create_connection function to create
5011 connection to remote router. My server implementation actually
5012 does not allow router to connect to normal server (it expects
5013 that normal server always initiates the connection to the router)
5014 so the CONNECT command is only good for connecting to another
5017 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5020 or some other client was kicked from the channel.
5022 Implemented the handling of the notify type to both client
5025 Implemented silc_server_send_notify_kicked to send the KICKED
5026 notify. It is used to send it to the server's primary router.
5028 * Implemented the KICK command into server and client.
5030 * Added `query' argument to the silc_idlist_get_client function
5031 to indicate whether to query the client from server or not if
5034 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5035 to indicate that the client is not channel founder.
5039 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5041 * Removed the rng context from SilcPacketContext structure and
5042 changed that the packet routine uses the Global RNG API.
5044 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Added support for quit message that client can "leave" on the
5047 channel when it quits the SILC. It is ditributed inside the
5048 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5050 Added silc_server_free_client_data that will take the
5051 signoff message as argument.
5053 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5055 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Updated parts of the protocol specification to keep it up
5060 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5063 payloads in one packet.
5065 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5066 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5067 use now the new List flag.
5069 * Also deprecated the following packet types: REPLACE_ID,
5070 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5072 * Added list support for Notify packet in server.
5074 * Added silc_server_send_notify_channel_change to send the
5075 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5076 the silc_server_send_replace_id.
5078 * Added silc_server_send_notify_nick_change to send the
5079 NICK_CHANGE notify type. Deprecates the function
5080 silc_server_send_replace_id.
5082 * Added silc_server_send_notify_join to send the JOIN notify type.
5083 Deprecates the function silc_server_send_new_channel_user.
5085 * Added silc_server_send_notify_leave to send LEAVE notify type.
5086 Deprecates the function silc_server_send_remove_channel_user.
5088 * Added silc_server_send_notify_cmode and
5089 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5090 types. Deprecates the silc_server_send_set_mode function.
5092 * Added SERVER_SIGNOFF notify type to indicate that server has
5093 quit. This means that all clients on the channel from that
5094 server will drop. This can be also used when netsplit happens.
5096 Deprecated REMOVE_ID packet type since it is not needed anymore
5099 Added silc_server_send_notify_server_signoff to send the
5100 SERVER_SIGNOFF notify type. Deprecates the function
5101 silc_server_send_remove_id.
5103 Added also silc_server_send_notify_signoff to send the
5104 SIGNOFF notify type.
5106 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5107 SILC protocol from this day on. Changed the protocol
5108 specification as well.
5110 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5111 notify type. It is used between routers to notify about
5112 topic changes on a channel.
5114 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5117 * Partly updated the protocol specification to comply with the
5118 changes now made. It is still though a bit outdated.
5120 * The JOIN notify type now takes one extra argument <Channel ID>.
5121 The packet used to be destined to the channel but now the
5122 JOIN type may be sent as list thus it is impossible to
5123 destine it to any specific channel. By adding this argument
5124 it is again possible.
5126 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added CREDITS file. The CHANGES and CREDITS file will appear
5129 in the distribution as well.
5131 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5134 types in the server's silcd/packet_receive.c.
5136 * Implemented CMODE and CUMODE to work in router environment.
5138 * Fixed minor encoding and decoding buglet from the
5139 lib/silccore/silcmode.c.
5141 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5144 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5146 * Changed all SilcConfigServer* and silc_config_server* to
5147 SilcServerConfig* and silc_server_config*, respectively.
5150 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Associated the ID (client or server ID) to the Authentication
5153 Payload to avoid any possibility of forging. Updated the
5154 protocol specification and the code accordingly.
5156 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * The RSA key length is now save to the RsaKey context in the
5159 key generation process in lib/silccrypt/rsa.c. The key length
5160 is now used to figure out the maximum size of the block allowed
5161 to be encrypted/signed.
5163 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5164 is equivalent to the silc_mp_mp2bin but does not allocate any
5167 * Changed silc_mp_mp2bin API to take length argument. If it is
5168 non-zero then the buffer is allocated that large. If zero, then
5169 the size is approximated using silc_mp_sizeinbase, which however
5172 * Created Global RNG API which is global RNG that application can
5173 initialize. After initializing, any routine anywhere in the
5174 code (including library) can use RNG without allocating a new
5175 RNG object. This was done to allow this sort of use of the
5176 RNG in code that has no chance to allocate RNG object. All
5177 applications currently allocate this and many routines in the
5178 library use this. Affected file lib/silccrypt/silcrng.[ch].
5180 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5181 it to use the Global RNG API.
5183 * Defined Authentication Payload into protocol specification that
5184 is used during SILC session to authenticate entities. It is
5185 used for example by client to authenticate itself to the server
5186 to obtain server operator privileges.
5188 Implemented this payload into the lib/silccore/silcauth.[ch].
5189 Implemented also routines for public key based authentication
5190 as the new protocol specification dictates.
5192 Moved definitions of different authentication methods from
5193 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5195 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5196 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5197 silc_pkcs_verify_with_hash functions into the file
5198 lib/silccrypt/silcpkcs.[ch].
5200 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * The client entry's userinfo pointer must be always valid.
5203 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5204 will fail since it requires the userinfo. Now, the userinfo
5205 is allocated as "" if actual userinfo does not exist. Actually,
5206 it must exist and it is totally Ok to drop client connections
5207 that does not announce the userinfo. However, we will make
5208 this workaround for now.
5210 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5211 to return the remote port by socket.
5213 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5216 SILC_SERVER_PENDING_EXEC and added an new macro
5217 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5218 data or when error occurs while processing the pending command.
5220 Added new argument `destructor' into silc_server_command_pending
5221 and to the SilcServerCommandPending object. This destructor is
5222 now called after calling the pending callback or if error occurs
5223 immediately. If error occurs the actual pending callback won't
5224 be called at all - only the destructor. The destructor may be
5225 NULL if destructor is not needed.
5227 All this applies for client library code as well. Similar
5228 changes were made there as well for the pending commands.
5230 In the client, the application must now allocate the
5231 SilcClientCommandContext with the silc_client_command_alloc
5234 * Added reference counter to the SilcServerCommandContext. Added
5235 function silc_server_command_alloc and silc_server_command_dup
5238 Same type of functions added to the client library for the same
5241 * Removed the cmd_ident from IDListData away since it is now
5242 global for all connections. It is the command identifier used
5243 in command sending and with pending commands. The affected file
5246 * Added reference counter to the SilcSocketConnection objecet to
5247 indicate the usage count of the object. The object won't be
5248 freed untill the reference counter hits zero. Currently only
5249 server uses this, and client ignores it. The client must be
5250 set to use this too later. The affected files are
5251 lib/silccore/silcsockconn.[ch]. Added also the function
5252 silc_socket_dup to increase the reference counter.
5254 This was mainly added because it is possible that the socket
5255 is removed underneath of pending command or other async
5256 operation. Now it won't be free'd and proper DISCONNECTING
5257 flags, etc. can be set to avoid sending data to connection that
5258 is not valid anymore.
5260 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5261 the connection. After that it sets SILC_SET_DISCONNECTED.
5262 It is, however, possible that the socket data is not still freed.
5263 The silc_server_packet_process now checks that data is not
5264 read or written to connection that is DISCONNECTED. The socket
5265 get's freed when the reference counter hits zero.
5267 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Changed the client operation API: channel_message operation's
5270 `sender' is now the client entry of the sender, not the nickname
5271 and the `channel' is the channel entry, not the channel name.
5273 In the private_message operation the `sender' is now also the
5274 client entry of the sender not the nickname.
5276 Affected file is lib/silcclient/ops.h and all applications
5277 using the client operations.
5279 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Moved the calling of ops->connect() from connect_to_server_final
5282 into receive_new_id functin since that is the point when the
5283 client is actually allowed to send traffic to network. The
5284 affected file is lib/silcclient/client.c.
5286 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5289 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5290 (if needs broadcasting) instead of broadcasting the packets one
5291 by one which would make a burst in the network traffic.
5293 * Added `broadcast' argument to the functions in silcd/server.[ch]
5294 silc_server_create_new_channel[_with_id] to indicate whether
5295 to send New Channel packet to primary router.
5297 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Added new function into the silcd/server.[ch] files:
5300 silc_server_create_new_channel_with_id to create new channel with
5301 already existing Channel ID.
5303 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5304 lib/silccore/silcpacket.h. This packet is used t send list of
5305 Set Mode payloads inside one packet. Server uses this to set
5306 the modes for the channels and clients on those channels, that it
5307 announced to the router when it connected to it. The protocol
5308 specification has been updated accordingly.
5310 * The silc_server_new_channel did not handle the packet coming
5311 from normal server as it normally does not send that. However,
5312 when it announces its channels it does send it. Implemented
5313 the support for that.
5315 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5316 into the file lib/silccore/id.h.
5318 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Fixed memory leaks in the functions silc_idlist_del_client,
5321 silc_idlist_del_channel and silc_idlist_del_server in the file
5322 silcd/idlist.c. All of those leaked like a sieve.
5324 * Fixed some small memory leaks in the client's function
5325 silc_client_notify_by_server.
5327 * Added functions into silcd/server.c: silc_server_announce_clients,
5328 silc_server_announce_channels and silc_server_announce_server.
5329 These functions are used by normal and router server to announce
5330 to its primary router about clients, channels and servers (when
5331 router) that we own. This is done after we've connected to the
5334 These functions effectively implements the following packet types:
5335 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5336 and SILC_PACKET_NEW_ID_LIST.
5338 * Added new functions into the silcd/packet_receive.[ch]:
5339 silc_server_new_id_list, silc_server_new_channel_list and
5340 silc_server_new_channel_user_list to handle the incoming
5341 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5343 * Added support of changing Channel ID in the function
5344 silc_server_replace_id. If the server that announces a channel
5345 to the router already exists in the router (with same name but
5346 with different Channel ID), router is responsible to send
5347 Replace ID packet to the server and force the server to change
5348 the Channel ID to the one router has.
5350 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5351 client that the Channel ID has been changed by the router. The
5352 normal server sends this to the client. Client must start using
5353 the new Channel ID as the channel's ID.
5355 Implemented handling of this new type into lib/silcclient/client.c
5356 into the function silc_client_notify_by_server.
5358 * Added new function silc_idlist_replace_channel_id into the files
5359 silcd/idlist.[ch] to replace the Channel ID.
5361 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Call silc_server_command_identify_check always when processing
5364 the IDENTIFY command in silcd/command.c
5366 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5369 send keepalive packets. The packet can be sent by clients,
5370 servers and routers.
5372 Added function silc_socket_set_heartbeat into the file
5373 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5374 If not set, the heartbeat is not performed. The actual
5375 heartbeat is implemented in the low level socket connection
5376 library. However, application is responsible of actually
5379 Added silc_server_send_heartbeat to send the actual heartbeat
5380 packet into silcd/packet_send.[ch]. Server now performs
5381 keepalive with all connections.
5383 * Added silc_task_get_first function into lib/silcutil/silctask.c
5384 to return the timeout task with shortest timeout. There was a bug
5385 in task unregistration that caused problems. TODO has been
5386 updated to include that task system must be rewritten.
5388 * The client library will now resolve the client information when
5389 receiving JOIN notify from server for client that we know but
5390 have incomplete information.
5392 * Rewrote parts of silc_server_remove_from_channels and
5393 silc_server_remove_from_one_channel as they did not remove the
5394 channel in some circumstances even though they should've.
5396 * Encryption problem encountered in server:
5398 The LEAVE command used to send the Channel Key packet to the
5399 router immediately after generating it. However, the code
5400 had earlier sent Remove Channel user packet but not immediately,
5401 ie. it was put to queue. The order of packets in the router
5402 was that Channel Key packet was first and Remove Channel User
5403 packet was second, even though they were encrypted in the
5404 reverse order. For this reason, MAC check failed. Now, this
5405 is fixed by not sending the Channel Key packet immediately but
5406 putting it to queue. However, this is more fundamental problem:
5407 packets that are in queue should actually not be encrypted
5408 because packets that are sent immediately gets encrypted
5409 actually with wrong IV (and thus MAC check fails). So, packets
5410 that are in queue should be encrypted when they are sent to
5411 the wire and not when they put to the queue.
5413 However, the problem is that the current system has not been
5414 designed to work that way. Instead, the packet is encrypted
5415 as soon as possible and left to the queue. The queue is then
5416 just purged into wire. There won't be any fixes for this
5417 any time soon. So, the current semantic for packet sending
5420 o If you send packet to remote host and do not force the send
5421 (the packet will be in queue) then all subsequent packets to the
5422 same remote host must also be put to the queue. Only after the
5423 queue has been purged is it safe again to force the packet
5426 o If you send all packets immediately then it safe to send
5427 any of subsequent packets through the queue, however, after
5428 the first packet is put to queue then any subsequent packets
5429 must also be put to the queue.
5431 Follow these rules and everything works fine.
5433 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Added new function silc_server_remove_clients_by_server to
5436 remove all client entries from ID list when the server connection
5437 is lost. In this case it is also important to invalidate all
5438 client entires as they hold the invalid server entry. This
5439 fixes fatal bug when server has lost connection and will reconnect
5442 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Made some sanity checks to silc_server_daemonise like to check
5445 whether the requested user and group actually exists.
5447 * Added sanity check to SKE's silc_ske_responder_finish to check
5448 that the public and private key actually is valid.
5450 * Invalidate the client's nickname when receiving Replace ID
5451 packet and the Client ID is being replaced. This means that the
5452 server will query the nickname if someone needs it (client)
5455 * Sort the ID Cache in client library when the ID Cache data
5456 has changed (needs sorting).
5458 * Do not allow for SILC client to create several connections to
5459 several servers. The client does not support windows right now
5460 and generating multiple connections causes weird behaviour.
5462 Irssi-silc client does support windows and can handle several
5463 connections without problems, see: www.irssi.org and SILC plugin.
5465 * Fixed some places where client was added to the IDList. The
5466 rule of thumb is following (in order to get everything right):
5467 If the client is directly connected local client then the
5468 `connection' argument must be set and `router' argument must be
5469 NULL to silc_idlist_add_client function. If the client is not
5470 directly connected client then the `router' argument must
5471 bet set and the `connection' argument must be NULL to the
5472 silc_idlist_add_client function.
5474 * The funtion silc_server_packet_send_local_channel actually did
5475 not check whether the client was locally connected or not. It
5476 does that now. Fixed a bug related to LEAVE command.
5478 * Fixed Remove Channel User payload parsing bug in server's
5479 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5481 * The server's silc_server_save_channel_key now checks also the
5482 global ID list for the channel as it might not be in the local
5483 list. Fixed a bug related to LEAVE command.
5485 * Is this the end of the [<unknown>] buglet that has been lurking
5486 around for a long time? A little for loop fix in server's
5487 silc_server_command_whois_parse that is used by both IDENTIFY
5488 and WHOIS command. At least, this was a clear bug and a cause
5489 of one type of [<unknown>] buglet.
5491 * WHOIS and IDENTIFY commands call the function
5492 silc_server_command_[whois/identify]_check function even if
5493 we are not router server.
5495 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Added --with-gmp configuration option. If set the GMP
5498 is always compiled in the SILC source tree. If not set then
5499 it is checked whether the system has the GMP3 installed. If
5500 it has then the GMP won't be compiled (the system's headers
5501 and library is used), if it doesn't have it then the GMP is
5502 compiled in the SILC source tree.
5504 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Changed RSA private exponent generation to what PKCS #1
5507 suggests. We try to find the smallest possible d by doing
5508 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5509 not security fix but optimization.
5511 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5513 * Added new config entry [Identity] to fork the server and run
5514 it as specific user and group. A patch from Bostik.
5516 * Imported Dotconf configuration library into lib/dotconf.
5517 This will be used to create the SILC configuration files later.
5518 It will appear in the distsribution after this commit.
5520 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * A big code auditing weekend happening. Auditing code for
5523 obvious mistakes, bugs and errors. Also, removing any code
5526 Removed files for being obsolete:
5528 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5529 inline in the file lib/silcutil/silcbuffer.h)
5531 o lib/silcutil/silcbufutil.c (the header has inline versions)
5533 Changed code to fix possible error conditions:
5535 o The buffer formatting routines now check that the destination
5536 buffer really has enough space to add the data. This applies for
5537 both buffer formatting and unformatting
5538 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5539 unformatting was changed to accomodate following rules:
5540 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5541 sent to the function while XXX_*STRING will not allocate or copy
5542 the data into the buffer. Instead it sets the pointer from the
5543 buffer into the pointer sent as argument (XXX_*STRING used to
5544 require that the pointer must be allocated already). This change
5545 makes this whole thing a bit more consistent and more optimized
5546 (note that the data returned in the unformatting with XXX_*STRING
5547 must not be freed now). The routines return now -1 on error.
5549 o Tried to find all code that use buffer_format and buffer_unformat
5550 and added return value checking to prevent formatting and
5551 especially unformatting errors and possible subsequent fatal
5554 o Changed ske->x and ske->KEY to mallocated pointers in
5555 lib/silcske/silcske.h. Fixed possible data and memory leak.
5557 o Added return value checking to all *_parse* functions. Fixed
5558 many memory leaks as well.
5560 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5561 so that buffer overflows would not happen. All code now also
5562 checks the return value as it can fail.
5564 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added reconnection support to server if the normal server looses
5567 its connection to the router (for example if router is rebooted).
5568 The server performs normal reconnection strategy implemented
5569 to the server. Affected file silcd/server.c.
5571 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Added new packet type SILC_PACKET_SET_MODE that is used to
5574 distribute the information about changed modes (for clients,
5575 channels and clients channel modes) to all routers in the
5576 network. Updated the protocol specification accordingly.
5578 Added functions into silcd/packet_send.c and
5579 silcd/packet_receive.c: silc_server_send_set_mode,
5580 silc_server_set_mode.
5582 Added new files silcmode.[ch] into lib/silccore that implements
5583 the encoding and decoding of Set Mode Payload. Added new type
5584 SilcSetModePayload. Moved the definitions of different modes
5585 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5587 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Oops, a little mistake in server's connection authentication
5590 protocol. The protocol is not ended with FAILURE but with
5591 SUCCESS if the authentication is Ok. :) Affected file is
5594 * Implemented NICK_CHANGE notify handling in server in the file
5595 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5596 the local clients on the channel. After the changing nickname
5597 in router environment snhould work and the [<unknown>] nickname
5598 should appear no more.
5600 The silc_server_replace_id function that receives the Replace ID
5601 payload now sends the NICK_CHANGE notify type also in the file
5602 silcd/packet_receive.c
5604 * Changed WHOIS and IDENTIFY command to support the maximum amount
5605 of arguments defined in protocol specs (3328 arguments). This
5606 fixed a bug that caused problems when there were more than three
5609 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added extra parameter, command identifier, to the
5612 silc_client_send_command so that explicit command identifier
5615 Changed that ID list routines uses specific command identifier
5616 when sending WHOIS/IDENTIFY requests to the server so that they
5617 can be identified when the reply comes back.
5619 Affected files lib/silcclient/command.[ch],
5620 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5622 * Added `sender' argument to silc_server_packet_send_to_channel
5623 to indicaet the sender who originally sent the packet to us
5624 that we are now re-sending. Ignored if NULL. Affected file
5625 silcd/packet_send.[ch].
5627 * Added some server statistics support in silcd/server_internal.h
5628 SilcServerStatistics structure and around the server code. Also
5629 send some nice statistics information when client is connecting
5632 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Fixed channel ID decoding in server's JOIN command reply in
5635 silcd/command_reply.c
5637 * Fixed braodcasting of replace ID payload to not to send it if
5638 we are standalone server in silcd/packet_receive.c.
5640 * Fixed all channel message sending routines to not to send
5641 packets to clients that has router set, since they are routed
5642 separately in the same function earlier. Affects file
5643 silcd/packet_send.c and all channel packet sending functions.
5645 * In USERS reply, res_argv[i] are not allocated, the table
5646 is allocated. Thus changed that free the table, not its
5649 * In server's whois_check and identify_check if the client is
5650 locally connected do not send any WHOIS commands - they are not
5653 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Fixed some minor bugs in client when sending WHOIS command. The
5656 arguments was in wrong order.
5658 * Removed statis function add_to_channel from server in
5659 silcd/command.c that was previously used with the joining but
5662 * Tested USERS command in router environment successfully with two
5663 routers, two servers and two clients.
5665 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Reorganized the USERS command and command reply in client library
5668 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5669 When the command is given by user we register a pending command
5670 callback that will reprocess the command after the reply has been
5671 received from the server. When reprocessing the packet we then
5672 display the information. Thus, the USERS information is displayed
5673 now in the command callback instead of in the command reply
5674 callback. The processing of the command is same as previously
5675 when server has sent the command reply in the JOINing process.
5677 * Added to USERS command in silcd/command_reply.c to join the client,
5678 we didn't use to know about, to the channel after we've created
5679 a client entry for it. Also, for clienet we did know already still
5680 check whether it is on the channel or not and add it if not.
5682 * Removed silc_server_command_join_notify as the function and its
5685 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Changed the client's pending command handling to the same as the
5688 server's pending command handling. It is also now possible to
5689 execute command reply functions from other command reply
5690 function as the function callbacks for commands and command
5691 replies are one and same. The pending commands are not static
5692 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5693 in client connection context. Thus, pending commands are server
5694 connection specific as it is convenient.
5696 Changed the function silc_client_command_pending and
5697 silc_client_command_pending_del and added new function
5698 silc_client_command_pending_check. Removed the
5699 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5702 * Added cmd_ident, current command identifier, to the client
5703 connection context in lib/silcclient/client.h to keep track on
5704 command identifiers used in command sending. Client's command reply
5705 function handling now supports the mandatory command identifiers.
5707 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5708 funtions in client to fully support pending command callbacks.
5710 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5711 as one of the arguments to the application in the command reply
5714 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5715 before first releasing SILC but came back. Now it is removed again
5716 and should come back nomore. The FORWARDED flag was used only
5717 by the JOINing procedure by forwarding the command packet to router.
5718 Now, the JOINing procedure has been changed to more generic (due
5719 to various router environment issues) and FORWARDED is not needed
5720 anymore for anything. The protocol specification is yet to be
5723 Now, removed silc_server_packet_forward from server and the flag
5724 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5726 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Renamed NAMES command to USERS command. The NAMES was named that
5729 due to historical reasons. Now it is renamed. Also, rewrote
5730 parts of the USERS command. The nickname list is not sent anymore
5731 by the server. Only Client ID and mode lists are sent in the USERS
5732 command. Changed this also to the protocol specification.
5734 The client now resolves the names and stuff after it receives
5735 the USERS list from the server when joining to the channel.
5737 * WHOIS and IDENTIFY commands has been changed to support multiple
5738 Client ID's per command. One can now search for multiple users
5739 in the network by sending only one WHOIS or IDENTIFY command.
5740 Changed the code and the protocol specifications.
5742 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5743 uses silc_server_command_whois_parse to parse the request. */
5745 * If normal server, do not parse the WHOIS and IDENTIFY requests
5746 before sending it to the router. Saves some time.
5748 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Fixed JOIN command on client library. Wrong number of arguments
5751 used to crash the client.
5753 * Added silc_server_channel_has_global function to check whether
5754 channel has global users or not.
5756 * Added silc_server_channel_has_local function to check whether channel
5757 has locally connected clients on the channel.
5759 * The silc_server_remove_from_one_channel now checks whether the
5760 channel has global users or not after given client was removed from
5761 the channel. It also checks whether the channel has local clients
5762 on the channel anymore. If it does not have then the channel entry
5763 is removed as it is not needed anymore.
5765 * The silc_server_notify now checks on JOIN notify whether the joining
5766 client is one of locally connected or global. If it is global then
5767 the channel has now global users on the channel and that is marked
5768 to the channel entry. Also, it now saves the global client to
5769 global list who is joining and JOINs it to the channel. This is
5770 for normal server, that is.
5772 Changed silc_server_send_notify_on_channel,
5773 silc_server_packet_relay_to_channel and
5774 silc_server_packet_send_to_channel check if we are normal server
5775 and client has router set (ie. global client) do not send the
5776 message to that client, as it is already routed to our router.
5778 * Implemented LEAVE notify type handling in silc_server_notify
5781 * Tested LEAVE command in router environment successfully. Tested
5782 with two routers, two servers and two clients.
5786 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5788 * Implemented SIGNOFF notify type handling in silc_server_notify
5791 * silc_server_remove_id now removes the client entry from all channels
5792 it has joined and thusly sends SIGNOFF notify type.
5794 * Rewrote the NAMES list generation in server by removing two excess
5795 loops. The lists are created now inside one loop.
5797 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * silc_server_remove_channel_user checks now also global list
5800 for channel and client.
5802 * silc_server_new_channel_user checks now both local and global
5803 list for channel and client. Fixed a bug in client id decoding.
5804 Used to decode wrong buffer.
5806 * silc_server_channel_message checks now both local and global
5807 list for channel entry.
5809 * Tested channel joining (hence JOIN) in router environment
5810 successfully. Tested with two routers, two servers and two
5813 * Tested channel message sending in router environment successfully.
5815 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Added silc_server_save_channel_key into server.[ch] to save the
5818 received channel key in Channel Key payload processing. It is
5819 also used in JOIN command reply handling.
5821 Equivalent function silc_client_save_channel_key added into
5822 client.[ch] into client library.
5824 * Changed JOIN command reply to send information whether the channel
5825 was created or not (is existing already) and the channel key
5826 payload. Changed protocol specs accordingly.
5828 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5829 the request was sent by ID and not by nickname. Crashed on
5832 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5835 now correctly save the received data.
5837 * silc_server_free_sock_user_data now notifies routers in the
5838 network about entities leaving the network.
5840 At the same time implemented functions silc_server_remove_id
5841 and silc_server_send_remove_id to receive and send REMOVE_ID
5842 packets. The packet is used to notify routers in the network
5843 about leaving entities. The ID removed will become invalid in
5846 * Added function silc_idlist_del_server into server. Removes and
5847 free's server entry from ID list.
5849 * silc_server_private_message function now checks, if we are router,
5850 that the destination ID really is valid ID, naturally.
5852 * In router when NEW_ID packet is received (for new client) the
5853 hash of the Client ID is saved in the ID Cache but the
5854 client->nickname is set to NULL, instead of putting the hash
5857 IDENTIFY command now also checks that client->nickname must be
5858 valid. If it is not if will request the data from the server who
5859 owns the client. Added new function
5860 silc_server_command_identify_check.
5862 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5863 to set the command to already allocated Command Payload.
5865 * Tested private message sending in router environment with two
5866 routers, two servers and two clients. Fixed minor bugs and now
5869 * Fixed segfault from client's NAMES command. Used to crash if
5872 * Forwarded packets must not be routed even if it is not destined
5873 to the receiver. Changed server code comply with this.
5875 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Added `require_reverse_mapping' boolean value to ServerParams
5878 structure. If TRUE (not default) the server will require that
5879 the connecting host has fully qualified domain name.
5881 If the reverse mapping is not required and hostname could not be
5882 found the IP address is used as hostname.
5884 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Implemented version string checking to both client and server.
5887 The check is incomplete currently due to the abnormal version
5888 strings used in development version of SILC.
5890 * Changed all command functions in server to use the new
5893 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Changed char *data to unsigned char *data in ID Cache system to
5896 support binary data as ID Cache data. Changed code to support
5897 binary data in lib/silccore/idcache.c.
5899 * Renamed silc_server_packet_relay_command_reply to
5900 silc_server_command_reply as it is normal packet receiving
5901 function. Rewrote the function to accept command replys for
5902 servers and not only for clients.
5904 * Mark remote router always as registered server if we are connecting
5905 to it. Otherwise, commands sent by the router to us are ignored.
5907 * All ID List find routines now returns the ID Cache Entry pointer
5908 as well if requested.
5910 * WHOIS command works now in router environment, tested with two
5911 routers, two servers and two clients.
5913 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5914 in router environment (as it is almost equivalent to WHOIS) but
5915 hasn't been tested thoroughly. Added new functions:
5917 silc_server_command_identify_parse
5918 silc_server_command_identify_send_reply
5919 silc_server_command_identify_from_client
5920 silc_server_command_identify_from_server
5922 * Disabled route cache adding because adding two different ID's with
5923 same IP replaces the old cache entry thus giving wrong route.
5924 The entry->router->connection is always the fastest route anyway
5925 so route cache may not be needed. Of course, new routes maybe
5926 established after receiving the ID when the entry->router->connection
5927 might not be anymore the most optimal.
5929 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Add route cache for received ID for fast routing.
5933 * Added silc_server_packet_route to route received packet on router
5934 that is not destined to us.
5936 * Renamed silc_server_get_route to silc_server_route_get.
5938 * Added id_string and id_string_len fields into SilcServer to
5939 include encoded ServerID for fast comparing without excess
5940 encoding of the ID's.
5942 * Cleaned up WHOIS command on server side. Added following static
5945 silc_server_command_whois_parse
5946 silc_server_command_whois_check
5947 silc_server_command_whois_send_reply
5948 silc_server_command_whois_from_client
5949 silc_server_command_whois_from_server
5951 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5952 arguments in command replies. All command functions should be
5953 updated to use this macro.
5955 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Minor typo fixes on command reply handling on server.
5959 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Added silc_server_command_add_to_channel internal routine to add
5962 the client to the channel after router has created the channel and
5963 sent command reply to the server.
5965 * Added generic silc_server_send_command to send any command from
5968 * Use static buffer with ID rendering instead of duplicating data.
5970 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Fixed a channel user mode bug when joining to a channel server gave
5973 everybody channel founder rights, oops.
5975 * We mark ourselves as the router of the incoming server connection
5976 if we are router ourselves. This way we can check in some packet
5977 sending functions whether it is locally connected server. For
5978 incoming router connections we put NULL.
5980 * For router sending packets locally means now always sending the
5981 packet cell wide; to local clients and local servers. For normal
5982 server sending packet locally means sending it to only local
5985 * Fixed the JOIN command to really work in router environment. If the
5986 channel is created it is always created by the router. Router is
5987 also responsible of making the initial joining to the channel,
5988 sending JOIN notify to the sending server and distributing
5989 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5990 does not exist server doesn't do anything else but forward the
5991 command to the router which performs everything.
5993 * Added silc_server_send_channel_key function to send the Channel Key
5996 * Added silc_server_create_channel_key to create new channel key. The
5997 channel key is now re-generated everytime someone joins or leaves
5998 a channel, as protocol dictates. Note: channel->key_len is the
6001 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6004 packet_receive.[ch] to separate packet sending and receiving
6005 routines. The server.[ch] now includes everything else including
6006 actual packet processing (writing and reading data) and other
6009 Renamed silc_server_private_message_send_internal to
6010 silc_server_send_private_message. The routine is still though
6011 used only to relay private messages as server does not send
6012 private messages itself.
6014 Renamed silc_server_new_channel to silc_server_create_new_channel
6015 and added new function sicl_server_new_channel that handles the
6016 incoming New Channel packet. Added also new sending function
6017 silc_server_send_new_channel to send New Channel Payload.
6019 * Added new function silc_server_notify to process incoming notify
6020 packet to the server/router. Server may then relay the notify
6021 to clients if needed.
6023 * Added new function silc_server_new_channel_user to process incoming
6024 New Channel User packet. Router will redistribute the packet and
6025 send JOIN notify to its local clients and locally connected servers
6026 if needed. Normal server will send JOIN notify to its local client
6027 on same channel when received this packet. Added also corresponding
6028 sending function silc_server_send_new_channel_user to sent the
6031 * Added boolean route argument to send_notif_to_channel and
6032 packet_send_to_channel functions to attempt to route the packet
6033 if it is TRUE and send only locally if it is FALSE.
6035 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * silc_server_replace_id now broadcasts the received replace ID
6038 packet if it is not broadcast packet already. The router must
6039 broadcast to inform other routers about changed ID.
6041 * Added backpointer to server's router into SilcServer context in
6042 silcd/server_internal.h.
6044 * Fixed silc_server_packet_broadcast to send correct broadcast
6047 * The channel key is now distributed to the local client as soon
6048 as it is received from the router (in router environment) so that
6049 no other packet may be sent for the channel until client has
6052 * silc_server_remove_channel_user now broadcasts the received
6053 Remove Channel User packet if it is not broadcast packet already.
6054 The router must broadcast to inform other routers about removed
6057 * Added users field into SilcPacketContext that is a reference count
6058 of the context. One can increase the reference count by calling
6059 silc_packet_context_dup which is now changed to just increase the
6060 reference count instead of duplicating the data. The reference
6061 count is decresed by calling silc_packet_context_free that will
6062 free the data after the reference count hits zero.
6064 For now on the packet context and everything allocated into it
6065 (including the raw packet from network) must be freed by calling
6066 the new silc_packet_context_free function. Added also new function
6067 silc_packet_context_alloc that must be used now to allocate the
6068 context. This also means that if a routine is asynchronous from
6069 silc_[client/server]_packet_parse_type the packet context must
6070 be duplicated by calling silc_packet_context_dup. Otherwise it
6071 gets free'd after silc_[client/server]_packet_parse_type returns.
6072 Also, one must remember that if packet is duplicated then its
6073 reference count must be decresed by calling the free function as
6074 many times as it was duplicated.
6076 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6077 from both client and server.
6079 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6081 * Made joining to a channel working in router environment.
6083 * Cleaned up JOIN command on server side and create function
6084 silc_server_command_join_channel internal routine to make the
6087 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Changed silc_command_pending list to SilcDList. Also, added
6090 `ident' field to SilcServerCommandPending structure to identify
6091 the reply and to call correct callback.
6093 Added silc_server_command_pending_check function to replace the
6094 corresnponding macro. The silc_command_pending list is not
6097 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6098 to set identifier to previously allocated Command Payload. It
6099 is used to set identifier for command when resending Command
6102 * Added silc_command_payload_encode_payload to encode Command
6103 Payload buffer from SilcCommandPayload structure.
6105 * Added silc_argument_payload_encode_payload to encode Argument
6106 payload buffer from SilcArgumentPayload structure.
6108 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Changed WHOIS command to support router connection on server side.
6111 The whois request is always sent to router unless the server is
6112 standalone server. After server has received the reply from the
6113 router will it send the reply to the client.
6115 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6116 broadcast received broadcast packet. The function is used only
6117 by router. The broadcast packet is always sent to the router's
6120 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6121 render given ID to printable string, for log files for example.
6123 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Made basic router to router connections working. At least they
6126 can now connect to each other but nothing really works the way
6127 they are supposed - yet.
6129 * Added new initiator token to RouterConnection configuration
6130 file in silcd/serverconfig.[ch]. It is used to tell whether we
6131 are the initiator to the remote router or whether we'll expect
6132 the other end to connect.
6134 * Moved registering of listener task to silc_server_init, hence
6135 the server starts listenning as soon as it is run, even if it
6136 does not have connections to other routers. Let's see how well
6139 * Changed default connection retry timeouts for more suitable in
6142 * Removed cipher and such arguments from silc_idlist_add_client
6143 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6144 Added new function silc_idlist_add_data to add the keys and stuff
6147 * Added SilcIDListData structure and added it to SilcClientEntry
6148 and SilcServerEntry as their first field in the structure. This
6149 way we can explicitly cast the ID entries to the SilcIDListData
6150 structure and get common data for the entries. In past, we had
6151 to first check what type of connection it is and then cast it to
6152 correct ID entry type. Now, we can directly cast the opaque
6153 pointer to the SilcIDListData (no matter what ID entry it actually
6154 is) and get the data needed.
6156 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6159 in some circumstances even if threre were timeout tasks, though not
6160 IO tasks, but tasks anyway. Now fixed.
6162 * Defined SilcServerConnection structure to hold connection specific
6163 stuff about directly connected servers and routers. The definition
6164 is currently in silcd/server_internal.h. I thought about having
6165 a bit more important role fro this struct but for now it is used
6166 only when connecting to other server (or router actually).
6168 * Added connecting retry support in server when connecting to
6169 router(s). The retry feature implement exponential backoff
6170 algorithm. Also, added SilcServerParams structure to hold default
6171 parameters for server. For now, it include these retry settings
6172 and are hard coded. After server is moded to be as Silc Server
6173 Library this structure will be more important.
6175 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Changed client librarys channel->clients table to SilcList and
6178 changed code accordingly.
6180 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6182 * Changed client's channel table to SilcList and changed code
6183 accordingly. Also changed SilcChannelClientEntry to include back-
6184 pointer to the channel so that client entry can use that structure
6185 as list as well and we have fast cross-reference to the channel.
6186 This change dramatically decreased the complexity of channel
6187 handling with client entry and vice versa (removed one extra
6188 loop when searching for channel entry from many functions).
6190 * Changed server->sim from table to SilcDList and changed code
6193 * NAMES command can now be used from user interface. It will show
6194 the user list on the channel, neatly.
6196 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6197 Code now saves realname of the user if it becomes available.
6199 * Renamed configure.in to configure.in.pre and made ./prepare
6200 script to automatically add correct version string to
6201 configure.in which it creates from configure.in.pre.
6203 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * NAMES command reply now shows users mode with the nickname when
6208 * Moved silc_client_ch[u]mode[_char] functions from
6209 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6210 place sucks, they are utility functions and should be in some
6213 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6215 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6218 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Added TRQ (efficient deque and list library) into lib/trq. This is
6223 a very good list library that is currently used in the SILC. Defined
6224 SilcList API over the library because I didn't like the API very
6225 much. See lib/trq/silclist.h for the API and examples of how to
6226 use the API. Fixed various places in the code to use the new
6227 SilcList API. The SilcList is meant for lists that has a structure
6228 already defined as a list. It is not suitable to add just some
6229 context to the list (in TRQ, the context is the list actually).
6231 So, I defined SilcDList that can be used for the purpose where
6232 predefined list structure does not exit. This can be used as
6233 such list. Now some context just can be added to the SilcDList.
6234 Currently this list is not used in the SILC just yet, though there
6235 are a lot places where this can replace dynamically allocated
6236 tables and I will fix these places, later, to use SilcDList.
6237 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6238 and use TRQ internally).
6240 Also fixed some annoying warning messages that the original TRQ
6241 code generated. Also minor changes to TRQ's Makefile.in.
6243 * Added support for querying by Client ID to both WHOIS and
6244 IDENTIFY commands into server, as required by the protocol.
6246 * Removed method function pointers from SilcBuffer structure. They
6247 weren't used to anything and just increased the context size for
6248 no good reason. This change also made silc_buffer_alloc and
6249 silc_buffer_free functions inline functions.
6251 * Disabled command flooding detection support until it's fixed so
6252 that it accepts commands in but does not execute them more than once
6255 * Added silc_net_localhost(), to return local hostname, into
6256 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6257 that must be initialized before calling silc_client_init.
6259 * Added new function: silc_server_send_notify_on_channels to send
6260 notify messages to all channels client has joined. It is assured
6261 that the message is sent only once per client.
6263 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6264 lib/silcutil/silcutil.[ch] as silc_format function. The new
6265 function is generic and is used by server as well, not only by
6266 the logging routines.
6268 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6269 the provided version string was not acceptable. Added new function:
6270 silc_ske_check_version into lib/silcske/silcske.h. The function
6271 must be implemented by the application (client or server) and it
6272 does not reside in the SKE library. The function checks the version
6273 string remote end sent.
6275 * Added back pointers (to opaque context and to SilcSocketConnection)
6276 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6278 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6279 duplicate packet context structure.
6281 * Changed `notify' client operation to send same arguments as client
6282 receives from server except for ID's. ID's are mapped to correct
6283 ID entry and that is returned. Also, if channel entry is not sent
6284 by server but the notify is for channel the channel entry is sent
6285 to application (otherwise application doesn't know that it is for
6286 channel (library gets it from packet's Destination ID)).
6288 * Added silc_client_remove_from_channels into client library to
6289 remove a client from all channels it has joined to. Used when
6290 received SIGNOFF notify from server. Added also new function
6291 silc_client_replace_from_channels to replace old ID entry with
6292 new ID entry on all channels. Used when received NICK_CHANGE
6295 * Fixed ID Cache list handling in silc_idlist_get_client in
6296 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6297 to get (or query) client by ID.
6299 * Updated TODO list.
6301 * Added connection authentication status message defined by the
6302 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6303 support for these into the code in client and server side.
6305 * Added generic function silc_client_send_command to send any command
6306 with variable argument list. Application should use this function
6307 to send commands if the command functions provided by the library
6308 does not suite for the application's user interface needs.
6310 * Added new `failure' client operation. Application is notified about
6311 received failure packet if client is executing a protocol. In this
6312 case the protocol's execution has failed.
6314 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6315 is required by the protocol.
6317 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6318 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6321 * Added status flag to SilcSKE object to indicate realtime status
6322 of the SKE protocol.
6324 * Application receives now exactly same command reply arguments as
6325 the library receives from server. However, if ID is received the
6326 corresponding ID entry is returned to the application (eg. Client
6327 ID is mapped to correct SilcClientEntry entry and that is returned).
6328 Changed command_reply client operation due to this change.
6330 * Changed all ID's in commands and in command replys as ID Payloads.
6331 Change affected both client and server side codes.
6333 All ID's sent in SILC network (with execption of ID's in SILC
6334 Packet header) are sent in ID Payload to support variable length
6337 * Server now notifies nick changes and notifies all clients on
6338 the channels about the new nickname (about the new Client ID,
6341 * Implemented CMODE command to change channel modes. Supports all
6342 channel modes defined by the protocol specs except ban and invite
6343 lists. (Also, private channel key mode is supported but support for
6344 setting private channel key in client is missing, thus, this mode
6345 has no effect on client side (except that server requires that the
6346 client uses private channel key and normal channel traffic does not
6349 Also, invite mode works per se, but INVITE command does not work
6350 yet correctly, so you can set channel as invite only channel but
6351 inviting clients to the channel does not work (it is yet to be
6352 thought what's the best way to do it).
6354 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6355 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6356 Implemented CUMODE command to change user's mode on the channel.
6357 Supports all modes defined by the protocol specs.
6359 * Added NAMES command reply to return users modes on the channel.
6361 * Removed unnecessary and slow ciphers from lib/silccrypt.
6363 * Set SO_KEEPALIVE option to connection sockets by default.
6365 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6367 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6368 redefined the Notify Payload into protocol specs.
6370 * Added silc_id_payload_parse_id to get ID directly from raw
6373 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6376 accept searching by Client ID as well.
6378 * Added support for LEAVE and SIGNOFF notify types in client library.
6380 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6381 to parse ID Payload from raw data.
6383 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Added flags parameter into silc_ske_assemble_security_properties
6386 function in lib/silcske/silcske.[ch].
6388 * Changed notify client operation to fit better for notify messages
6389 sent by server. The notify payload received from server is now
6390 passed to the application (after parsing it to SilcNotifyPayload).
6391 It is application's responsibility to retrieve the arguments
6392 from the payload and show the message the way it wants. The message
6393 sent by server is implementation specific.
6395 * Changed public keys to comply with the protocol specification.
6396 Old public keys are not supported anymore and are not compatible.
6398 * Removed nickname from Channel Payload as the latest draft removed
6399 it. The client must resolve the nickname from the NAMES command
6400 reply received when it joined the channel.
6402 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6404 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Fixed some errors in protocol specification drafts.
6408 * Created lib/silccore/silcnotify.c to implement Notify Payload
6409 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6410 generic payloads described by protocol specifications. The file
6411 includes implementations for ID Payload and Argument Payload.
6413 * Changed Command Payload implementation to use the new Argument
6414 Payload. Changed command_xxxx_payload to command_payload_xxxx
6415 to comply with SILC coding conventions.
6417 * Added suppport for Argument Payload handling in Notify Payload
6418 implementation as protocol requires it. Added the new support
6419 into server and client lib as well.
6421 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Added support for multiple nicknames on same channel. [n] is
6424 added locally to the nickname if there are more than one same
6425 nicknames on the channel.
6427 * Server now sends all nicknames that matched WHOIS request.
6428 Client also shows the list received from server.
6430 * Added TOPIC command to client side. User can now set and show
6431 current topic on channel.
6433 * Added MOTD command to client and server. Also, server sends the
6434 motd when client connects to the server.
6436 * Changed version strings to comply ISO 8601.
6438 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Fixed protocol error handling in client library. It should now
6441 cope even if the SKE fails for some reason.
6443 * Made new protocol specification drafts for submitting to IETF.
6445 * Implemented TOPIC command to server in silcd/command.c.
6447 * Added two new notify types into lib/silccore/silcnotify.h:
6448 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6449 notify nickname change and topic setting/change on a channel.
6451 * API change of command_reply operation in client library. The
6452 application gets now the status type received from server as well.
6454 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6456 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6458 * Cras fixed and optimized the packet handling even further and
6459 it should work now. Minor change to the prototype of function
6460 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6462 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added new function into lib/silcutil/silcschedule.[ch]:
6465 silc_schedule_with_fd to select() a specified fd. The function
6466 returns after timeout expires or data arrives or goes. The
6467 function is used by packet routines to wait that all data is
6468 received from network.
6470 * Fixed data reading from network in lib/silccore/silcpacket.c.
6471 The code now assures that all data is read from the fd and then
6472 continues packet processing. This was a bug fix since the code
6473 used to drop some data in some circumstances.
6475 * Added new function into lib/silcclient/client.[ch]:
6476 silc_client_start_key_exchange to start key exchange after
6477 connection has been established to server. The code internally
6478 now uses this funtion but its main purpose was to provide it
6479 for applications that perform their own connecting. After
6480 application has created a connection it merely calls this
6481 function to start the key exchange between client and server.
6482 The library takes care of everything else after that.
6484 Updated also lib/silcclient/README to explain the usage of
6487 * Do not send to application information that connection has
6488 been established. Application gets notified it by connect
6491 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Applied cras's patch to add silc_schedule_one function. The
6494 function runs scheduler once and returns.
6496 * Fixed the scheduler after cras messed it up. The timeout
6497 handling works now as it's supposed to work.
6499 * Added into lib/silccore/ silcnotify.h to include notify
6500 message types support. Changed silc_server_send_notify*
6501 functions, in server.[ch], to support those new notify types.
6502 Added the support for the notify types into client library,
6503 as well. Added new notify client operation into ops.h in
6506 * Changed silc_server_packet_send_to_channel to send normal
6507 packets instead of just channel message packets. The function
6508 is now used to send the notify packets to channels. It is not
6509 used to send channel message packets anymore, as server never
6512 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6513 va_arg()s as it seems to require it nowadays. I guess, if SILC
6514 is compiled with older va_arg() the new code should work anyway.
6516 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6518 * Splitted core library. Core library (lib/silccore) includes
6519 now only SILC protocol specific core (and common) components.
6520 Created new utility library (lib/silcutil) that includes more
6521 generic purpose stuff. The stuff for util library was taken
6522 from the old core library. This was minor and easy split.
6524 * Created SILC Client Library (lib/silcclient) that includes
6525 implementation of the SILC client without user interface. This
6526 was major move from silc/ directory. The code has been changed
6527 so that it is transparent towards the user interface. The
6528 silc/ directory includes now the same user interface as before
6529 and it uses the new client library. Read lib/silcclient/README.
6530 Basicly, the client library performs everything else related
6531 to SILC except user interface handling. Also, configuration
6532 files are considered to be part of user interface and library
6533 does not handle them.
6535 This change also changed a lot of structures, function naming etc.
6536 Most important change was that SilcClientWindow object was
6537 renamed to SilcClientConnection in the client library. Created
6538 also new file lib/silcclient/ops.h. Also added new files
6539 silc/local_command.[ch] and silc/client_ops.[ch].
6541 All these changes were made to make it easier for user interface
6542 designers to create what ever user interface for the SILC client
6545 It is also expected that the server will be moved to lib
6546 directory as well and SILC Server Library will be created;
6547 sometimes in the future.
6549 * Removed Local commands from lib/silccore/silccommand.h as
6550 they are application specific and new client library does not
6551 handle any of those anymore.
6553 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6554 old client implementation in silc/.
6556 * Added support for callback functions in SILC_LOG_* macros.
6557 Application can now set its own callbacks that will be called
6558 instead of using the default functions that will always print
6559 the debug messages to stderr (or stdout). Also, debugging can
6560 now be disabled by setting silc_debug to FALSE and re-enabled by
6561 setting it to TRUE. Note, that logging will still work even
6562 if debugging is disabled.
6564 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6565 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6566 silc_log_reset_debug_callbacks.
6568 * To enable debugging in silc client one must give now -d
6569 option on command line.
6571 * Changed silc_schedule_init to automatically allocate task queues
6572 if they are not allocated before calling it.
6574 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Added GMP 3.1 into math library.
6578 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6581 a channel in SILC network. The packet is used by servers and
6582 routers to notify other routers that user has left a channel.
6583 This little feature was missing until now. Added the feature
6584 to protocol specification as well.
6586 Added functions: silc_server_send_remove_channel_user and
6587 silc_server_remove_channel_user into server.[ch].
6589 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6590 lib/silccore/silcpacket.h. However, they are not implemented
6593 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Fixed joining to a channel and sending channel messages
6596 between server and router. The channel message sending should
6597 now work inside a cell.
6599 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6601 * Fixed the private message sending between server and router.
6602 The private message sending should now work inside a cell.
6604 * Added silc_server_replace_id into server.[ch] to replace
6605 existing ID in the SILC network.
6607 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6608 and silc_idlist_replace_server_id into idlist.[ch] in server.
6610 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Fixed the server to server connections. Server can again now
6613 connect to router. Router to router connections probably does
6616 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added dynamic protocol registering support. Now protocols can
6619 registered and unregistered on the fly. Patch by cras.
6621 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Added lib/contrib directory to hold routines that some platforms
6624 don't have but are needed by SILC.
6626 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6627 into lin/contrib to provide getopt() and getopt_long() for
6628 those who don't have it.
6630 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6632 * Added AWAY command to client. When away message is set and
6633 client receives a private message packet the client automatically
6634 replies to the sender with the away message.
6636 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6637 bug seemed to be the cause of recent problems when compiling
6640 * Added version detection support to SKE protocol specification
6641 and added the new changes to the SKE implementation as well.
6642 There were other minor changes in the SKE protocol as well.
6644 Many changes in lib/silcske/silcske.[ch] and in
6645 lib/silcske/payload.[ch].
6647 * Added ^U functionality, clear input line. Patch from cras.
6649 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Mainly small bugfixes on core library. Fixed some debugging
6652 logging and buffer overflow in silclog.c.
6654 * Updated config.sub and config.guess on the distribution tree.
6656 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Added command lagging support in server. Client may execute
6659 commands now only once in two seconds.
6661 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Optimized packet reception. MAC computation and checking is now
6664 also more optimized. A lot previously duplicated code is now
6665 used as generic by both client and server.
6667 * Fixed key pair generation in clientutil.c
6669 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Added into lib/silccore/silcbufutil.[ch] new function;
6672 silc_buffer_realloc.
6674 * Moved generic packet sending/encryption functions to
6675 lib/silccore/silcpacket.[ch] from client and server. Some
6676 rewriting of the functions.
6678 * Moved all generic packet reception/decryption functions to
6679 lib/silccore/silcpacket.[ch] from client and server. The
6680 packet processing is now much cleaner in both client and server.
6681 These were major changes in both client and server.
6683 * Created many common functions in server to do packet sending.
6684 Previously code were duplicated a lot, this has been removed
6687 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Rewrote major parts of the ID cache system. Don't know
6690 whether it is better now or not but at least the API is more
6693 * Major rewrite on ID cache stuff on client because of the ID
6694 cache API changes. Added idlist.c to client.
6696 * Also major rewrite on ID cache stuff on server as well.
6697 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6698 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6699 in hand, instead they are all put into the ID cache system now.
6700 All server_idlist_* routines uses ID cache now instead of
6701 traversing its own lists (those lists does not exist anymore).
6702 SilcIDList though still exists. Also, SilcXXXEntry's are
6705 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Finally made the SKE implementation compliant to the protocol
6708 specification. All mp integers are now binary encoded as
6709 opposed being HEX encoded.
6711 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6714 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6715 functions: silc_[encode/decode]_pem. Also added function
6716 silc_encode_pem_file to PEM encode with newlines ('\n') for
6719 * SILC public keys are now encoded either PEM or binary. Same
6720 option is for private keys as well. By default private keys
6721 are binary encoded and public keys PEM encoded. Silly HEX
6722 encoding were removed.
6724 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6725 function to create fingerprints.
6727 * Fixed a bug in SHA1; does not change the original data anymore.
6729 * Partly implemented INFO command on client and server side.
6730 Fixed CLEAR command. Changes to SERVER command; show current
6731 server(s) when giving command without arguments. Added
6732 VERSION command to client.
6734 * Added check to server that unregistered connections cannot
6735 execute commands (unless it is specificly allowed).
6737 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Fixed screen refresh.
6741 * Fixed channel joining bug from client. On some circumstances
6742 client tried to join to a channel it had already joined.
6744 * Added public key verification process into client's protocol.c.
6745 The client now verifies the public key from user and saves
6746 it into ~./silc/serverkeys/ directory.
6748 Added into: clientutil.[ch]: silc_client_verify_server_key.
6750 * Changed SKE protocol's silc_ske_initiator_finish function
6751 to accept callback function that verifies the received public
6752 key. Removed old silc_ske_verify_public_key function.
6754 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6757 silc_pkcs_private_key[_data]_set.
6759 * Made the password and public authentication more cleaner in
6760 server's protocol.c.
6762 * Removed historic and obsolete protocol `channel_auth' from
6763 both client and server.
6765 * Removed wrong way of sending command status messages from
6766 server to client in server's command.c. The old way violated
6767 protocol specification.
6769 Changes to silccore/silccommand.[ch]: removed
6770 silc_command_encode_status_payload -> not needed anymore,
6771 changed silc_command_encode_payload_va to accept extra
6772 argument on variable argument list. The argument type must
6773 now be provided to the function. Also, added new function:
6774 silc_command_encode_reply_payload_va which is same as
6775 normal command_encode_payload_va except command status type
6776 is provided as extra argument.
6778 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added ~./silc directory handling. The directory includes the
6781 public and private keys for the client.
6783 Added silc_client_check_silc_dir, silc_client_create_identifier
6784 and silc_client_load_keys.
6786 * Implemented SILC protocol compliant public key. Added public
6787 and private key saving to and loading from files.
6789 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6790 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6791 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6792 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6793 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6795 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6796 silc_pkcs_load_[public/private]_key.
6798 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Added silc_server_get_route (route.[ch]) to get connection
6801 data for the fastest route for given ID.
6803 * Implemented INVITE command on client and server. The command
6804 were re-defined in the SILC Protocol Specification and the
6805 implementation now complies with the specification.
6807 * Implemented PING command on client and server.
6809 * Implemented NAMES command on client and server. The server side
6810 supports currently only normal server not router server yet.
6811 Some changes to NAMES definition in SILC protocol specification.
6813 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Implemented LEAVE command on client and server.
6817 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6818 again. This change was made to the protocol as well. Server
6819 should not violate the protocol specification anymore.
6821 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6823 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6824 was tested. SOCKS4 was not but should work anyway.
