1 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Added server & router operator statistics updating. Affected
4 file silcd/packet_receive.c and silcd/command.c.
6 * Fixed the SERVER_SIGNOFF notify handling on normal server
7 not to save the history information for clients. Same was
8 fixed earlier in remove_clients_by_server function, but not
9 here. Affected file silcd/packet_receive.c.
11 * Raised the default connection-retry count from 4 to 7 in
12 server. Affected file silcd/server.h.
14 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
16 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
18 * Fixed the NICK command to always give the unformatted
19 nickname to the one giving the NICK command. If unformatted
20 nickname is cached already it will be formatted and the
21 local entry will always get the unformatted nickname.
22 Affected file lib/silcclient/idlist.c.
24 * Fixed some double frees from client library commands.
25 Affected file is lib/silcclient/command.c.
27 * Fixed CUMODE command in server to assure that no one can
28 change founder's mode than the founder itself, there was a
29 little bug. Affected file silcd/command.c.
31 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
33 * Removed the SilcClientCommandDestructor from the client
34 libary, it is not needed anymore. Affected files are
35 lib/silcclient/silcapi.h, command[_reply].[ch],
36 client_notify, idlist.c.
38 * Fixed GETKEY command to first resolve client, and then
39 resolve the server only if the client was not found, instead
40 of resolving both at the same time. Affected file is
41 lib/silcclient/command.c.
43 * Added silc_client_start_key_exchange_cb and lookup the
44 remote hostname and IP address before starting the key
45 exchange with server. The affected file is
46 lib/silcclient/client.c.
48 * The server's public key is now saved using the IP address
49 of the server and not the servername for the filename.
50 The hostname public key filename is checked as an fall back
51 method if the IP address based filename is not found.
53 Fixed the GETKEY command to save the fetched server key
56 Print the remote server's hostname now when new key is
57 received during connection process. Affected file is
58 irssi/src/silc/core/client_ops.c.
60 * Return always our own public key to the client if it asks
61 for it with GETKEY command. Affected file silcd/command.c.
63 * Removed the use_auto_addr variable from default config
64 file since it was in wrong section. Affected file is
67 * Fixed TOPIC_CHANGE notification to not route it when it
68 was sent using silc_server_send_notify_to_channel function.
69 Affected file silcd/command.c.
71 * Fixed silc_server_send_notify_kicked to send the kicker's
72 Client ID also, it was missing. Affected files are
73 silcd/command.c, silcd/packet_send.[ch].
75 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Do not save client history information in SERVER_SIGNOFF.
78 Fixes the bug in normal server that it does not detect
79 the client becoming valid after the server becomes back
80 online. Affected file silcd/server_util.c.
82 * Added `sock_error' field into the SilcSocketConnection
83 context. When error occurs during socket operation (read
84 or write) the error is saved. Added also new function
85 silc_socket_get_error to return human readable socket error
86 message. Affected files are lib/silcutil/silcsockconn.[ch],
87 lib/silcutil/unix/silcunixsockconn.c, and
88 lib/silcutil/win32/silcwin32sockconn.c.
90 * The server now prints the socket error message in the
91 signoff for client. Affected file silcd/server.c.
93 * Fixed the `created' channel information sending from router
94 to server in JOIN command. Checks now whether the channel
95 really was created or not and set it according that.
97 Fixed the JOIN command to use the client entry's current
98 ID during the joining procedure instead of the one it sent
99 in the command (it is checked though), since it can change
100 between the packet processing and command processing, and
101 would just case unnecessary pain in the client end. Affected
102 file silcd/command.c.
104 * Fixed a channel key payload sending to use correct channel
105 ID when the server was forced to change the channel's ID by
106 router. Router sent the key payload with the old Channel ID.
107 Affected file silcd/packet_receive.c.
109 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Call silc_server_save_channel_key only if the key payload
112 was provided in the JOIN command's command reply. Affected
113 file silcd/command_reply.c.
115 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
117 * Fixed silc_mp_sizeinbase to return the value correctly with
118 MPI. Affected file lib/silcmath/mp_mpi.c.
120 * Fixed the stop_server signal to correctly stop the scheduler
121 and gracefully stop the server when SIGTERM or SIGINT signals
122 are received. Affected file silcd/silcd.c.
124 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
126 * Simple handling of TERM and HUP signals. Also added some log
127 flushing call around. Affected file is
130 * Fixed small bugs in silclog.c. Now buffering output will take
131 effect after 10 seconds since startup: This will ensure that
132 no important startup messages are lost. Also output redirection
133 will preserve original format ([Date] [Type] message).
134 Affected file is lib/silcutil/silclog.c.
136 * Added two options to the config file, in the logging section:
137 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
138 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
140 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
142 * Do not print the warning about log files not being initialized
143 more than once to avoid excess logging. Affected file is
144 lib/silcutil/silclog.c.
146 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
147 the SIM copying in make install in Makefile.am.pre.
149 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
151 * Rewritten silclog APIs. Globally interesting changes follows:
152 silc_log_set_files() changed to silc_log_set_file().
153 silc_log_set_callbacks() changed to silc_log_set_callback().
154 ROBOdoc documented silclog header file.
155 SilcLogCb now returns bool to wether inihibit the default
156 handler or not (to keep the old behaviour return always TRUE).
157 The new APIs should also fix the problem of the
158 silcd_error.log file that was written in the current directory.
161 Log files streams will remain opened after silc_log_set_file()
162 call, means less CPU usage notably on high traffic servers.
163 File streams are now full buffered, and flushed to the disk
164 every 5 minutes, lesses HD activity and CPU usage.
165 Messages can be redirected, allowing admins to configure
166 one single logfile for all server messages.
167 the silc_log_quick global variable to activate fast-logging.
168 Affected files lib/silcutil/silclog.[ch]
170 * Changed some code to conform new silclog APIs. Affected
171 files are doc/example_silcd.conf.in, silcd/server.c
172 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
175 * Fixed a memory leak that could occur in some situations.
176 Affected file silcd/serverconfig.c.
178 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
180 * Added the silc_client_del_client to remove the client from
181 all channels as well. Affected file lib/silcclient/idlist.c.
183 * Fixed the client library to correctly remove the client
184 from all channels when the client entry is being destroyed.
185 Affected file lib/silcclient/client_notify.c, command.c.
187 * Added auto-nicking support to the client library. If the
188 applicatio now sets client->nickname it will be sent to the
189 server after connecting by the library. This way for example
190 SILCNICK (or IRCNICK) environment variables will have effect
191 and always change the nickname automatically to whatever
192 it is wanted. Affected file lib/silcclient/client.[ch].
194 * Renamed silc_server_command_bad_chars to the
195 silc_server_name_bad_chars and moved it to the
196 silcd/server_util.[ch]. Added also new function
197 silc_server_name_modify_bad to return nickname that
198 includes bad characters as new nickname without those
199 bad characters. This check and modify is now used in
200 silc_server_new_client when the username is initially set
201 as nickname, so it must be checked to be valid nickname.
202 Affected file silcd/packet_receive.c.
204 * The nickname length is now taken from the packet for real
205 and not trusted to strlen() since it clearly can return
206 wrong length for nickname including bad characters. This
207 also applies to channel names. Affected file silcd/command.c.
209 * Removed the lib/silcsilm/modules directory. Modules are now
210 compiled into the lib/silcsim. Fixed the copying of the
211 modules to follow symbolic links in Makefile.am.pre.
213 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
215 * Fixed silc_string_regexify list creation. Fixes bugs with
216 BAN and INVITE commands in server. The affected file is
217 lib/silcutil/unix/silcunixutil.c.
219 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
221 * Removed the command destructor entirely from the server's
222 command and command reply routines. It is not needed, and
223 its usage was buggy and caused crashes. Affected files are
224 silcd/command[_reply].[ch].
226 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
228 * Cancel protocol and NULL sock->protocol if timeout
229 occurred during protocol. Affected file silcd/server.c.
231 * Cancel protocol timeouts always before calling the final
232 callback, to assure that after final callback is called
233 no other state will be called for the protocol anymore.
234 Affected file silcd/protocol.c.
236 * Print error log if incoming connection configuration could
237 not be found. Affected file silcd/server.c.
239 * Fixed JOIN command to correctly save the founder mode
240 to the client on normal SILC server, when the channel
241 was created by the router. Affected file silcd/command.c.
243 * Fixed LIST command (hopefully) to send correct reply
244 packets. Affected file silcd/command.c.
246 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
248 * The silc_packet_receive_process now returns FALSE if the
249 read data was invalid packet, and TRUE if it was ok.
251 The server now checks that if unauthenticated connection
252 sends data and its processing fails the server will close
253 the connection since it could be a malicious flooder.
255 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
257 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
259 * Make sure the warning about error opening a log file is
260 printed only once and not everytime it fails (produces
261 too much useless log). Affected file lib/silcutil/silclog.c.
263 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
265 * Made the silc_server_daemonise() function more readable.
266 Affected file silcd/server.c.
268 * Pid file is now optional, the user may comment it out from
269 the config file. Removed define SILC_SERVER_PID_FILE, we
270 don't need a default any longer. Affected file
271 configure.in.pre, lib/Makefile.am.pre.
273 * Make some use of the pid file. The server now dies at startup
274 if it detects a valid pid file on his path. The server would
275 die anyway in this circumstance, because of the bind() failure.
276 Affected file silcd/silcd.c.
278 * No longer compiling lib/dotconf.
280 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
282 * Fixed JOIN command parsing not to crash. Affected file
283 lib/silcclient/command.c.
285 * Fied the NICK_CHANGE notify to add the new client entry
286 even it is resolved. This removes an <[unknown]> nick
287 thingy bug in the client. Affected file is
288 lib/silcclient/client_notify.c.
290 * Do not try to allocate 0 bytes (efence does not like it)
291 in lib/silccore/silccomand.c when encoding payload.
293 * Do not take IRCNICK as nickname in Irssi SILC client since
294 it is not possible to set nickname before hand connecting
295 the server (TODO has an entry about adding auto-nicking
298 * Changed the silc_server_command_pending to check whether
299 there already exists an pending entry with the specified
300 command, command identifier and pending callback. This is
301 to fix IDENTIFY and WHOIS related crashes that may register
302 multiple pending commands with same identifier. Affected
303 file silcd/command.c.
305 * Fixed the server to reconnect to the router even if it
306 was already reconnecting and EOF was received. This to
307 fix a possibility that the server wouldn't ever try to
308 auto-reconnect to the router. Affected file silcd/server.c.
310 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Fixed the server's password authentication to use the
313 length of the locally saved password, and not the one
314 sent in the packet. Affected file silcd/protocol.c.
316 * Fixed same password authentication problem in the
317 Authentication Payload handling routines in
318 lib/silccore/silcauth.c.
320 * Yet another password authentication problem fixed with
321 channel password handling in silcd/command.c.
323 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
325 * If first character of string in silc_parse_userfqdn is '@'
326 then do not parse it. Affected file is
327 lib/silcutil/silcutil.c.
329 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
331 * Fixed minor bug in IDENTIFY command reply sending, which
332 caused various weird problems during JOIN when it was
333 resolving names for users. Affected file silcd/command.c.
335 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Fixed the IDENTIFY command reply sending to chech better valid
338 clients. It was possible to send incomplete list of replies.
339 Affected file silcd/command.c.
341 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
343 * Added silc_client_command[s]_[un]register functions now to
344 dynamically register the commands in client library. Removed
345 the static table of commands. This allows the client library
346 to call commands without causing the application to know about
347 what commands library has called.
349 Removed the INFO command reply kludge to detect when the command
350 was called by library. Now library use its own command reply
351 function for INFO command.
353 Added function silc_client_command_call to call a command.
354 Application can use it to call command, not access the structure
357 Now all commands that are sent by the client library (not
358 explicitly sent by application) use own command reply functions.
360 Affected files around lib/silcclient/ and in
361 irssi/src/silc/core/.
363 * Fixed the WHOIS command reply sending to chech better valid
364 clients. It was possible to send incomplete list of replies.
366 Fixed the WHOIS and IDENTIFY to send the request to router
367 if normal server did not do it and did not find any results.
369 Affected file silcd/command.c.
371 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
373 * Moved the internal data from SilcClient context into its
374 own file, not accesible to application. Affected files
375 lib/silcclient/client.h and lib/silcclient/client_internal.h,
376 and other files in client library.
378 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
380 * Added doc/examples installation target in Makefile.am.pre.
383 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
385 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
386 commands the found client entry will be removed from the
387 cache, after notifying application about the error. Affected
388 file lib/silcclient/command_reply.c.
390 * Changed the /MSG to check for exact nickname user gave, and
391 not let `nick' match `nick@host' if it is only one found. Now,
392 user must type the exact nickname (like nick@host2) even if
393 there are no more than one same nicks found. This is to avoid
394 a possibility of sending nickname to wrong nickname since
395 `nick' could match `nick@host'. Affected file is
396 irssi/src/core/silc-servers.c.
398 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
400 * Do not print "you are now server operator" or similar when
401 giving /away command. Affected files are
402 irssi/src/silc/core/client_ops.c, silc-servers.h.
404 * Made the silc_server_command_pending_error_check to send
405 the same command reply payload it received back to the
406 original sender of the command. This way all arguments
407 that was received by the server will be received by the
408 client too. Affected file silcd/command.c.
410 * Added the silc_idcache_add to return the created cache entry
411 to a pointer. Affected file lib/silccore/silcidcache.[ch].
413 * Add global clients to expire if they are not on any channel.
414 This is because normal server will never know if they signoff
415 if they are not on any channel. The cache expiry will take
416 case of these entries. This is done by normal servers only.
417 The affected files are silcd/command_reply.c,
418 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
420 * If server receives invalid ID notification for WHOIS or
421 IDENTIFY and the ID exists in the lists, it is removed.
422 Affected file silcd/command_reply.c.
424 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
425 in client then client entry that it matches is searched and
426 the nickname is printed on the screen for user. Affected
427 file irssi/src/silc/core/client_ops.c.
429 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Use cache entry expire time in the LIST command reply to
432 purge old entries from the cache after the LIST command
433 reply has been received. This way we don't have non-existent
434 entries in the cache for too long. Affected file is
435 silcd/command_reply.c.
437 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
439 * If we are normal server, and we've not resolved client info
440 in WHOIS or IDENTIFY from router, and it is global client,
441 we'll check whether it is on some channel. If it is not
442 then we cannot be sure about its validity and will resolve it
443 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
444 file silcd/command.c.
446 * Search channel by name (if possible) rather than by ID
447 in IDENTIFY command's command reply. Affected file is
448 silcd/command_reply.c.
450 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
452 * Distribute to the channel passphrase in CMODE_CHANGE notify.
453 Updated specs and implemented it. Affected file silcd/command.c,
454 silcd/packet_send.c and silcd/packet_receive.c.
456 * Implemented the <founder auth> payload handling in the JOIN
457 command. If provided all conditions for channel joining
458 except requirement to provide correct passphrase can be
459 overrided by the channel founder. Updated the protocol specs.
460 Affected file silcd/command.c.
462 Added support for founder auth in JOIN command in client
463 library. Fixed the parsing of the JOIN command now to support
464 all options as they should be. The affected file is
465 lib/silcclient/command.c.
467 * Optimized the WHOIS and IDENTIFY commands to send the request
468 to router only if it includes nicknames or other names. If
469 they include only IDs then check the local cache first before
470 routing. Affected file is silcd/command.c.
472 * Added channels topic announcements. Affected file is
473 silcd/packet_receive.c and silcd/server.c.
475 * Fixed the silc_server_send_notify_topic_set to really destine
476 the packet to channel. Affected file silcd/packet_send.c.
478 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
479 library. Affected file lib/silcclient/client_notify.c.
481 * Added UMODE announcements. Affected file silcd/server.c.
483 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
485 * Memory leak fixes in:
487 lib/silcutil/silcsockconn.c
488 lib/silcske/silcske.c
491 lib/silccrypt/silcpkcs.c
492 lib/silccore/silccommand.c
493 lib/silccore/silcidcache.c
498 * ROBOdoc documented the lib/silcske/groups.h file and a
499 bit changed the interface for better.
501 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
503 * Update the client entry context in the ID cache after
504 nick change. Affected file lib/silcclient/command.c.
505 Fixes the CUMODE command when regaining founder privileges,
506 and a little WHOIS problem.
508 * Fixed silc_net_gethostbyname to correctly call the
509 inet_ntop. Affected file lib/silcutil/silcnet.c.
511 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
513 * Added IPv6 support checking to the configure.in.pre, added
514 also --enable-ipv6 option to override the check. Affected
515 file configure.in.pre.
517 * The silc_thread_create now calls the start function
518 directly if threads support is not compiled in. Removes
519 ugly #ifdef's from generic code. Affected files are
520 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
522 * Added silc_net_gethostby[name/addr]_async to asynchronously
523 resolve. Affected files are lib/silcutil/silcnet.[ch].
525 * Added support for rendering IPv6 based server, client and
526 channel IDs. Affected file lib/silcutil/silcutil.c.
528 * Added support for creating IPv6 based server IDs. Affected
529 file is silcd/serverid.c.
531 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
533 * Added silc_net_gethostby[addr/name] into the
534 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
535 routines. Added silc_net_is_ip[4/6]. Affected file is
536 lib/silcutil/unix/silcunixnet.c. All routines that take
537 address as argument now supports both IPv4 and IPv6 addresses.
539 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
541 * Fixed LIST command reply sending in server. Affected file
544 * Server now sends the kicker's client ID in the KICK notify
545 to the kicked client. Affected file silcd/command.c.
547 * The client library now parses the kickers client ID and
548 UI displays it. Affected files lib/silcclient/client_notify.c
549 and irssi/src/silc/core/silc-channels.c, module-formats.c.
551 * Made all payload parsing function prototypes consistent.
552 They all take now const unsigned char * and uint32 pair as
553 the payload data instead of SilcBuffer. Changes all around
554 the source tree. Other unsigned char* -> const unsigned char*
555 changes around the tree as well.
557 * Optimized SFTP client and server packet sending not to
558 allocate new buffer for each packet but to recycle the
559 first allocated buffer. Affected files are
560 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
562 * Optimized the SFTP client to use SilcList instead of
563 SilcDList for requests, because it is faster. Affected file
564 is lib/silcsftp/sftp_client.c.
566 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
567 into lib/silccore/silcid.[ch].
569 Renamed silcpayload.[ch] into silcargument.[ch].
571 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
573 * If client entry is deleted with active key agreement
574 session, abort the session.
576 The silc_client_abort_key_agreement now calls the completion
577 callback with new SILC_KEY_AGREEMENT_ABORTED status.
579 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
582 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
584 * Don't use __restrict in older GCC's. Affected file is
585 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
587 * silc_net_localhost now attempts to reverse lookup the
588 IP/hostname. Affected file lib/silcutil/silcnet.c.
590 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
591 command. It can be used to gain founder privileges at
592 the same time when joining the channel.
594 Defined that the SILC_NOTIFY_TYPE_KICKED send the
595 kicker's client ID as well. Updated protocol specs.
597 Defined that the server must send SILC_COMMAND_IDENTIFY
598 command reply with error status to client who sent
599 private message with invalid client ID.
601 Updated the protocol specification.
603 * Added silc_server_send_command_reply to send any
604 command reply. Affected file silcd/packet_send.[ch].
606 * Added silc_id_payload_encode_data to encode ID payload
607 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
609 * The server now send IDENTIFY command reply with error
610 status if client ID in private message is invalid. Affected
611 file silcd/packet_receive.c.
613 * Save the server key file with server's IP address in
614 the filename instead of hostname. The affected file is
615 irssi/src/silc/core/client_ops.c.
617 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
622 * Added libtool support for compiling shared objects in
623 lib/silcsim. Affected file configure.in.pre and
624 lib/silcsim/Makefile.am. Original patch by cras.
626 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
628 * Pid file configuration, and server's config file fixes
629 patch by toma. Updated CREDITS file.
631 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
633 * Fixed silc_client_channel_message to not try to decrypt
634 the message twice if it resolved the destination client
635 information. This could cause of dropping one channel
636 message. Affected file lib/silcclient/client_channel.c.
638 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Added silc_client_run_one into lib/silcclient/silcapi.h and
641 lib/silcclient/client.c. This function is used when the SILC
642 Client is run under some other scheduler, or event loop or
643 main loop. On GUI applications, for example this may be
644 desired to used to run the client under the GUI application's
645 main loop. Typically the GUI application would register an
646 idle task that calls this function multiple times in a second
647 to quickly process the SILC specific data.
649 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
651 * Fixed silc_server_drop() for dropping the supplementary
652 groups as well, this could cause a security hole on some
655 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
657 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

661 to run server on foreground. A patch by debolaz.
662 Affected files silcd/server.c, silcd/silcd.c.
664 * Fixed MOTD to return the MOTD file server name. Affected
665 file silcd/command.c.
667 * Added INFO command reply handling to the Irssi SILC Client.
668 Affected file irssi/src/silc/core/client_ops.c.
670 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
672 * Fixed the silc_idcache_list_* routines to really support
673 the dynamic list. Fixes a crash. Affected file is
674 lib/silccore/silcidcache.c.
676 * Fixed the LIST command reply to really call LIST command's
677 pending callbacks. Affected file silcd/command_reply.c.
679 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
681 * Update conn->local_entry->nickname after giving NICK
682 command. Affected file lib/silcclient/command.c.
684 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
686 * Added the [pid] option to the silcd configuration file
688 Affected files: serverconfig.[ch] and silcd.c
690 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Save fingerprint in WHOIS command reply in server.
693 Affected file silcd/command_reply.c.
695 * Fixed NICK commands pending callback registration.
696 Affected file lib/silcclient/command.c.
698 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Use ++server->cmd_ident when sending commands in server,
701 instead of random number. Affected file silcd/command.c.
703 * Fixed GETKEY command reply to call actually GETKEY pending
704 command callbacks. Affected file silcd/command_reply.c.
706 * A bit stricter check for nicknames. Check for same nickname
707 in NICK command also. Affected file silcd/command.c.
709 * Do not call INFO command everytime client ID changes, only
710 during first connecting. Affected file lib/silcclient/client.c.
712 * Set the new nickname only after successful command reply for
713 NICK command is returned by server. Affected file
714 lib/silcclient/command.c.
716 * Remove nicknames from nicklist during server_signoff notify.
717 Should fix /NAMES bit more. The affected file is
718 irssi/src/silc/core/silc-channels.c.
720 * Added `fingerprint' field to the SilcIDListData in the
721 silcd/idlist.h to hold the fingerprint of the client's
724 Send the fingerprint of the client's public key in WHOIS
727 Affected files silcd/command.c, and silcd/idlist.[ch].
729 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
730 create fingerprint from given data.
732 * Show the fingerprint of the client's public key in WHOIS.
733 Affected files irssi/src/module-formats.[ch] and
734 irssi/src/silc/core/client_ops.c.
736 * Format the multiple same nicknames also during JOIN and
737 NICK_CHANGE notifys. Affected file is
738 lib/silcclient/client_notify.c.
740 * Do not print error on screen for invalid private message
741 payload since it can come if someone is sending private
742 messages with wrong key. Affected file
743 lib/silccore/silcprivate.c.
745 * Fixed multiple concurrent /PING crash. Affected file
746 lib/silcclient/command.c.
748 * Changed the wrong ID encoding. All IP addresses must be
749 in MSB first order in encoded format. They were encoded
750 wrong and was in LSB format. Affected files are
751 silcd/serverid.c, lib/silcutil/silcutil.c.
753 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
755 * Call the `connect' client operation through the scheduler
756 in case of error. Affected file lib/silcclient/client.c.
758 * Call the `failure' client operation even if the error
759 occurred locally during a protocol. Affected file is
760 lib/silcclient/protocol.c.
762 * Added support of sending LIST command to router from normal
763 server. This way normal server can get list of all channels
764 in the network too. Fixed the channel list sending in the
765 server too. Affected files are silcd/command.c, and
766 silcd/command_reply.[ch].
768 * Added silc_server_update_channels_by_server and
769 silc_server_remove_channels_by_server. They are used during
770 disconnection of primary router and in backup router protocol.
771 Affected file silcd/server_util.[ch], silcd/server.c and
772 silcd/server_backup.c.
774 * Fixed channel adding to global list in IDENTIFY command
775 reply in server. Affected file silcd/command_reply.c.
777 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
779 * If the incoming packet type is REKEY or REKEY_DONE process
780 that packet always synchronously. Fixes yet another MAC
781 failed error on slow (dialup) connections. Affected file
782 lib/silcclient/client.c and silcd/server.c.
784 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
786 * Call check_version SKE callback for initiator too. Affected
787 file lib/silcske/silcske.c.
789 * Implemented fix for security hole found in the SKE that was
790 fixed in the specification few days back; the initiator's
791 public key is now added to the HASH value computation.
792 Added backwards support for the old way of doing it too, for
793 old clients and old servers. Affected file is
794 lib/silcske/silcske.c.
796 * Enabled mutual authentication by default in SKE. If initiator
797 is not providing mutual authentication the responder will
798 force it. This will provide the proof of posession of the
799 private key for responder. The affected files are
800 lib/silcclient/protocol.c and silcd/protocol.c.
802 * Do not cache anymore the server's public key during SKE.
803 We do mutual authentication so the proof of posession of
804 private key is done, and if the server is authenticated in
805 conn auth protocol with public key we must have the public
806 key already. Affected file silcd/protocol.c.
808 * Added new global debug variable: silc_debug_hexdump. If
809 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
810 file lib/silcutil/silclog.[ch].
812 * Fixed compilation warning due to char * -> const char *.
813 Affected files lib/silcutil/silcnet.h, and
814 lib/silccore/silcauth.[ch].
816 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Fixed CMODE command when new channel key was created. If
819 the creation failed the old key was removed. Next time giving
820 same command would crash the server since the old key was
821 freed already. Affected file silcd/command.c.
823 * Fixed the silc_server_announce_get_channels to not crash
824 on reconnect. Affected file silcd/server.c.
826 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Added silc_log_set_debug_string function to set a regex
829 string to match for debug output. Only the function names,
830 or filenames matching the given debug string is actually
831 printed. This way it is possible to filter out those debug
832 strings that user is not interested in.
834 Fixed a bug in silc_string_regexify.
836 Affected files lib/silcutil/silclog.[ch], and
837 lib/silcutil/unix/silcunixutil.c.
839 * Changed the -d options in both server and Irssi SILC client
840 to take the debug string as argument. Affected files
841 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
843 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
845 * Added silc_hash_babbleprint to create a Bubble Babble
846 Encoded fingerprint. The encoding is developed by Antti
847 Huima (draft-huima-babble-01.txt), and it creates human
848 readable strings out of binary data. Affected file
849 lib/silccrypt/silchash.[ch].
851 * Print the babble print now in addition of fingerprint as well
852 in Irssi SILC client. Affected files are
853 irssi/src/fe-common/silc/module-formats.[ch],
854 irssi/src/fe-common/silc/core/client_ops.c.
856 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Fixed a security problem found in SKE. The initiator's
859 public key too is now added to the HASH hash value creation
860 which is signed by the responder to create the SIGN value.
861 This will prevent anyone in the middle to lie to the responder
862 about the initiator's public key. If this is done now, the
863 man in the middle will get caught. Updated the protocol
866 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
868 * Better installation directory handling. Configure module
869 paths and other paths automatically to example_silc* files
870 in doc/. A patch by toma.
872 * Fixed compiler warning from MPI library, and from SILC RNG.
875 * Added SILC_SERVER_PID_FILE to define the pid file for server.
876 It can be configured with ./configure. A patch by toma.
878 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Find correct make to use in prepare-clean. A patch by
881 toma. Affected file prepare-clean.
883 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
885 * Added irssi variables use_auto_addr, auto_bind_ip,
886 auto_bind_port and auto_public_ip.
888 * Changed the interface for silc_client_send_key_agreement
889 in lib/silcclient/silcapi.h
893 irssi/src/silc/core/silc-core.c
895 lib/silcclient/silcapi.h
896 irssi/src/silc/core/silc-channels.c
897 lib/silcclient/client_keyagr.c
900 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
902 * Added silc_pkcs_public_key_compare to compare two
903 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
905 * Check that the client who set the founder mode on the
906 channel is the same client that is giving the founder
907 mode to itself. It is done by comparing the saved public
908 key (it is saved even in the authentication is passphrase).
909 Affected file silcd/command.c.
911 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
913 * Do not process packet for disconnected socket connection.
914 Affected file lib/silccore/silcpacket.c.
916 * Process the DISCONNECT packet through scheduler in the
917 client library. Affected file lib/silcclient/client.c.
919 * Fixed the silc_client_packet_parse to not to increase
920 the packet sequence number if the conn->sock and the
921 current socket connection is not same. This can happen
922 for example during key agreement when the conn includes
923 multiple socket connections (listeners). Affected file
924 lib/silcclient/client.c.
926 * The sender of the file transfer request now provides also
927 the pointer (listener) for the key exchange protocol. If
928 the listener cannot be created then it sends empty key
929 agreement and lets the receiver provide the listener.
931 Added `local_ip' and `local_port' arguments to the
932 silc_client_file_send. If they are provided they are used,
933 if not then it will attempt to find local IP address, if
934 not found or bind fails then the remote client will provide
937 Affected files are lib/silcclient/client_ftp.c and
938 lib/silcclient/silcapi.h.
940 * Extended the FILE SEND command to support defining the
941 local IP and port for key exchange listener. They are
942 optional. Affected file irssi/src/silc/core/silc-servers.c.
944 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Defined to WHOIS command reply the sending of fingerprint
947 of the client's public key (if the proof of posession of the
948 corresponding private key is verified by the server).
949 Updated to the protocol specification.
951 * Added support of receiving the client's public key's
952 fingerprint in command reply in client library. Affected
953 file is lib/silcclient/command_reply.c, and
954 lib/silcclient/idlist.[ch].
956 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Do not send over 128 chars long nickname to the server
959 in NICK command. Affected file lib/silcclient/command.c.
961 * Do not send over 256 chars long channel names to the server
962 in JOIN command. Affected file lib/silcclient/command.c.
964 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
966 * Assure that silc_server_close_connection cannot be called
967 twice for same socket context. Affected file is
970 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
972 * Send error message to application if opening file for
973 writing during file transfer fails. Affected file is
974 lib/silcclient/client_ftp.c.
976 Remove all file transfer sessions for a client that we're
977 removing from ID cache.
979 Affected file is lib/silcclient/client_ftp.c.
981 * Fixed silc_net_addr2bin to return correct address. Affected
982 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
984 * Fixed file transfer session removing on signoff notify.
985 Affected file irssi/src/silc/core/silc-servers.c.
987 * Added the SilcClientFileError to be returned in the monitor
988 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
989 Affected file lib/silcclient/silcapi.h.
991 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Fixed a crash in silc_client_ftp_free_sessions and
994 silc_client_ftp_session_free_client. Affected file
995 lib/silcclient/client_ftp.c.
997 * Added `disabled' field in the SilcChannelEntry in the server
998 to indicate if the server entry is disabled. Affected file
999 silcd/idlist.h, silcd/command[_reply].c.
1001 * SILC server adds now /var/run/silcd.pid everytime it is
1002 started. Affected file silcd/silcd.c.
1004 * Added silc_server_packet_send_clients to send a packet to
1005 the provided table of client entries. Affected file
1006 silcd/packet_send.[ch].
1008 * Fixed a crash in client resolving in client_prvmsg.c in
1009 client library. Affected file lib/silcclient/client_prvmsg.c.
1011 * Do not actually remove the client directly from ID cache
1012 during SERVER_SIGNOFF, but invalidate it. This way we
1013 preserve the WHOWAS info for the client. Affected file
1014 silcd/server_util.c.
1016 * Fixed SERVER_SIGNOFF notify handling in the server. The
1017 server is now able to process incoming SERVER_SIGNOFF notify
1018 for a server that it doesn't even know about. It will remove
1019 the clients provided in the notify. Affected file
1020 silcd/packet_receive.c.
1022 * Check for partial packet in data queue after every packet that
1023 was found from the queue. Return and wait for more data if
1024 there is partial data in queue. Affected file is
1025 lib/silccore/silcpacket.c.
1027 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1029 * Added SilcClietFileError enum to indicate error in
1030 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1031 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1032 Affected files lib/silcclient/silcapi.h and

1035 * Check that newsize in silc_buffer_realloc is larger than
1036 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1038 * Added better monitor of file transfers. It now monitors
1039 key agreement protocol during the file transfer too. Added
1040 error reporting too. Affected files
1041 irssi/src/silc/core/silc-servers.c,
1042 irssi/src/fe-common/silc/module-formats.[ch].
1044 * Wrote a help file for FILE command.
1046 * Added silc_rng_global_get_byte_fast to get not-so-secure
1047 random data as fast as possible. Random data is read from
1048 /dev/urandom if available and from the SILC RNG if not
1049 available. It is used in padding generation. Affected file
1050 lib/silccrypt/silcrng.[ch].
1052 * All packets in client library are now processed synchronously.
1053 Optimized packet processing a lot. Affected file
1054 lib/silcclient/client.c.
1056 * All server connection packets are processing synchronously
1057 now in server, to optimize packet processing. Affected file
1060 * Include files are installed now only in Toolkit distribution
1061 if make install is given. Affected files: all Makefile.am's.
1063 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Assure that silc_client_notify_by_server_resolve does not
1066 resolve the client information multiple times. If it cannot
1067 be found by the first it cannot be found at all. Affected
1068 file lib/silcclient/client_notify.c.
1070 * Fixed WHOWAS command reply calling. Affected file
1071 lib/silcclient/command_reply.c.
1073 * Removed all references to silc_idlist_get_client from the
1074 Irssi SILC client since that call is internal call used by
1075 the library. The Irssi SILC client will use now client
1076 retrieval functions found in silcapi.h.
1078 * Fixed a bug in resolving nickname info before sending
1079 private message. It used freed memory. Affected file
1080 irssi/src/silc/core/silc-servers.c.
1082 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1084 * Assure my_channels statistics cannot go negative in server.
1085 Affected files silcd/server.c, silcd/server_util.c.
1087 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1091 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1093 * Win32 Toolkit changes. Affected files
1094 win32/silc.dsw, win32/libsilc/libsilc.def,
1095 win32/libsilcclient/libsilc.def,
1096 lib/silcutil/silcutil.c, and
1097 lib/sftp/sftp_fs_memory.c.
1099 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Added silc_net_localip to return local host's IP address.
1102 Affected file lib/silcutil/silcnet.[ch].
1104 * If key exchange or rekey protocol is active for a connection
1105 parse all packets syncronously since there might be packets
1106 in packet queue that we are not able to process without first
1107 processing packets before them. Affected file silcd/server,
1108 lib/silcclient/client.c.
1110 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1111 whether library should continue processing the packet.
1112 Affected file lib/silccore/silcpacket.h.

1138 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Renamed silc_file_read and silc_file_write to functions
1141 silc_file_readfile and silc_file_writefile. Added function
1142 silc_file_open and silc_file_close. Affected files
1143 lib/silcutil/silcutil.[ch].
1145 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Resolve the client info when received private message or
1148 channel message for a client which nickname we don't know.
1149 Affected files lib/silcclient/client_prvmsg.c and
1150 lib/silcclient/client_channel.c.
1152 * Do not crash in /KEY if client is not connected. Affected
1153 file irssi/src/silc/core/silc-channels.c.
1155 * Added SilcClientStatus field to the SilcClientEntry in the
1156 lib/silcclient/idlist.h.
1158 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1159 is incomplete and is being resolved, it won't be resolved
1162 Make sure also that USERS command reply does not resolve
1163 twice information. Affected file is
1164 lib/silcclient/command_reply.c.
1166 Make sure that silc_client_get_clients_by_list does not
1167 resolve twice same information.
1169 * Check for valid client->id in the silc_server_free_client_data.
1170 Affected file silcd/server.c.
1172 * Fixed /GETKEY nick@server not to crash if the server entry
1173 is not found. Affected file lib/silcclient/command.c.
1175 * Fixed the silc_server_check_cmode_rights to check the
1176 requested modes correctly. Affected file silcd/command.c.
1178 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1180 * Better checks for non-printable chars in nick added.
1181 Affected file silcd/command.c.
1183 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Call the silc_server_udpate_servers_by_server in the
1186 primary router that comes back online in the backup resuming
1187 protocol. Otherwise it routes packets wrong. Affected file
1188 silcd/server_util.[ch], silcd/server_backup.c.
1190 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1193 lib/silcutil/silcbuffmt.[ch].
1195 * Redefined the SILC packet header to include the padding
1196 length. Affected file lib/silccore/silcpacket.[ch].
1198 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1199 length for maximum padding up to 128 bytes). Affected
1200 file lib/silccore/silcpacket.h.
1202 * Removed all backwards support for old 0.5.x MAC thingies.
1203 The SILC packet header change makes it impossible to be
1204 backwards compatible.
1206 * Send the ENDING packet with timeout in the backup resuming
1207 protocol. This is to assure that all routers has connected
1208 to the primary router. Affected file silcd/server_backup.c.
1210 * Changed the RNG to take the first IV from random data. It
1211 used to take it from zero actually. Changed the RNG also
1212 to use /dev/urandom during session. /dev/random is used
1213 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1215 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Changed the SILC packet header to have the first two bytes
1218 (the packet length) encrypted. Affected files aroung the
1219 code tree, lib/silccore/silcpacket.[ch]. Removed the
1220 SilcPacketCheckDecrypt callback. It is not needed anymore
1221 since the silc_packet_receive_process will determine now
1222 whether the packet is normal or special.
1224 * Implemented the unidirectional MAC keys. Affected files
1225 lib/silcske/silcske.c, silcd/protocol.c and
1226 lib/silcclient/protocol.c.
1228 * Implemented the packet sequence number to the MAC computation.
1229 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1230 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1231 lib/silcclient/protocol.c.
1233 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Allow backup router to announce servers. All servers
1236 announced by backup router are added to the global list
1237 automatically. Update hte server's socket to our primary
1238 router also when backup router announces a server.
1239 Affected file silcd/packet_receive.c.
1241 * Do not update the client->router in the function
1242 silc_server_udpate_clients_by_server if the client is on
1243 global list. We might fail to find any specific server
1244 for locally connected clients and local cell clients. They
1245 should still use the `from' and not `to' as client->router.
1246 This fixes backup router resuming protocol. Affected file
1247 silcd/server_util.c.
1249 * Decrease channel statistics count only if the channel
1250 deletion worked. Affected files are silcd/server.c and
1251 silcd/server_util.c.
1253 * Added silc_server_update_servers_by_server to update origin
1254 of all server entries. Used during backup router protocol.
1255 Affected files silcd/server_util.[ch], silcd/server.c. and
1256 silcd/backup_router.c.
1258 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1259 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1260 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1261 lib/silccrypt/silchmac.c.
1263 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Assure that router cannot reroute the same channel message
1266 to the sender. Affected file silcd/packet_receive.c.
1268 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Made better checks that the channel message is not sent
1271 to the router it came from. Affected file is
1272 silcd/packet_send.c. Fixed memory leak too.
1274 * Announce informations for incoming router connection, but
1275 only after checking if it is replaced by backup router.
1276 Affected file silcd/packet_receive.c.
1278 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Fixed the backup resuming protocol to work in multiple
1281 router environment. Affected file silcd/server_backup.c.
1283 * Route packet only to one router in the function
1284 silc_server_packet_send_to_channel. Affected file is
1285 silcd/packet_send.c.
1287 * Fixed silc_server_send_notify_dest to set the broadcast
1288 flag. Fixed the silc_server_send_notify_topic to actually
1289 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1290 Affected file silcd/packet_send.c.
1292 * Changed the SFTP Filesystem interface. Changed the
1293 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1294 the filesystem operation function. The SilcSFTPFilesystem
1295 is now a context that is allocated by all filesystem allocation
1296 functions and it already includes the operations structure
1297 and filesystem specific context. It is given as argument
1298 now to the silc_sftp_server_start. This made the interface
1299 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1300 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1302 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Changed the backup router adding and getting interfaces
1305 in the server. The router that will be replaced by the
1306 specified backup router is now sent as argument. Affected
1307 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1310 * Added silc_net_addr2bin_ne to return the binary form of
1311 the IP address in network byte order. Affected files
1312 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1314 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Check for existing server ID in silc_server_new_server
1317 and in silc_server_connect_to_router_final and remove the
1318 old entry if it exists. Affected file silcd/packet_receive.c,
1321 * Send the channel message always to only one router, either
1322 in upstream or downstream. Affected file is
1323 silcd/packet_send.c.
1325 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Wrote the definition of the backup resuming protocol to the
1328 protocol specification.
1330 * Removed one redundant channel key generation from normal
1331 server during joining procedure. Removed one redundant
1332 channel key sending from server to router during joining
1333 procedure. Affected file silcd/command.c.
1335 * Made minor bugfixes to the backup router resuming protocol.
1336 Affected file silcd/server_backup.c, server.c.
1338 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Added --disable-asm configuration option. Affected files
1341 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1344 * Implemented the backup resuming protocol that is used to
1345 resume the primary router position in the cell after the
1346 primary router comes back online. Affected files
1347 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1348 and silcd/server_util.[ch].
1350 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Sleep two (2) seconds after sending QUIT command to server.
1353 Affected file lib/silcclient/command.c.
1355 * Assure that if outgoing data buffer is pending do not force
1356 send any data. Affected file silcd/packet_send.c.
1358 * Assure that if outgoing data buffer is pending do not force
1359 send any data. Affected file lib/silcclient/client.c.
1361 * Implemented the backup router support when the primary router
1362 goes down. The servers and routers can now use the backup
1363 router as new primary router without loosing connectivity.
1365 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1367 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1368 in the server to indicate disabled entry. All data read
1369 from the connection will be ignored and no data is sent
1370 for entry that is disabled. Affected files are
1371 silcd/idlist.h, silcd/server.c.
1373 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Created SFTP client and server test programs in the
1376 lib/silcsftp/tests directory.
1378 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Implemented memory filesystem (virtual filesystem) for
1381 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1384 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Implemented the SFTP (SSH File Transfer Protocol) to the
1387 lib/silcsftp. It includes SFTP client and SFTP server
1390 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Moved lib/silccore/silcprotocol.[ch] to the
1393 lib/silcutil library.
1395 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1396 take variable argument list pointer as argument. Affected
1397 file lib/silcutil/silcbuffmt.[ch].
1399 * Added silc_buffer_set function that is used to set data
1400 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1401 Affected file lib/silcutil/silcbuffer.h.
1403 * Changed various routines in the core library to use the new
1404 silc_buffer_set instead of allocating new buffer only for
1407 * Added 64-bit value formatting and unformatting support to the
1408 silc_buffer_[un]format routines. Affected file is
1409 lib/silcutil/silcbuffmt.[ch].
1411 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1412 to includes/bitmove.h.
1414 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Fixed channel user mode saving in client library. Affected
1417 file lib/silcclient/command[_reply].c.
1419 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Defined the file transfer to the SILC Protocol. Added
1422 new packet type SILC_PACKET_FTP and defined File Transfer
1423 Payload. The mandatory file transfer protocol is SFTP
1424 (SSH File Transfer Protocol). Affected file in addition
1425 of the internet draft is lib/silccore/silcpacket.h.
1427 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1428 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1429 is used as part of backup router protocol when the primary
1430 router of the cell is back online and wishes to resume
1431 the position as primary router.
1433 * Redefined the MAC generation keys in the protocol. The
1434 same key is not used anymore in both direction. Both
1435 direction will now use different keys for sending and
1436 receiving. This fixes a potential security flaw. This
1437 change causes incompatibilities in the protocol.
1439 * Redefined also the MAC computation from the packet.
1440 An packet sequence number is now added to the MAC
1441 computation. This prevents possible replay attacks against
1442 the protocol. This change too causes incompatibilities
1445 Added `sequence' field to the SilcPacketContext to hold
1446 the current sequence number for the packet.
1448 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Added `created' field to the SilcIDListData in the file
1451 silcd/idlist.h to indicate the time when the entry was
1454 * Added `created' field to the SilcChannelEntry too. Affected
1455 file silcd/idlist.h.
1457 * Added `creation_time' aguments to all the announcement functions
1458 in the server. If it is provided then only the entries that
1459 was created after the provided time frame are actually
1460 announced. Affected file silcd/server.[ch].
1462 * The protocol says that the Channel ID's IP address must be
1463 based on the router's IP address. Added check for this in
1464 the silc_server_new_channel when processing incoming New Channel
1465 Payload. Affected file silcd/packet_receive.c.
1467 * Print out the correct version with --version in SILC client.
1468 Affected file irssi/src/silc/core/silc-core.c.
1470 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Fixed WHOWAS command to check for completnes of the client
1473 entry always, not just when the command is coming from client.
1474 Affected file silcd/command.c.
1476 * Added new function silc_server_packet_queue_purge to purge the
1477 outgoing data queue to the network. After the function returns
1478 it is guaranteed that the outgoing packet queue is empty.
1479 Affected file silcd/packet_send.[ch].
1481 * Purge the outgoing packet queue in the rekey protocol's final
1482 callback to assure that all rekey packets go to the network
1483 before quitting the protocol. Affected file silcd/server.c.
1485 * Added silc_client_packet_queue_parse as similar function as
1486 in server to the client library. The affected file is
1487 lib/silcclient/client.c.
1489 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1491 * Splitted silcd/server.c and created silcd/server_util.[ch]
1492 for utility functions.
1494 * Added new socket flag SILC_SF_DISABLED to indicate that the
1495 connection is open but nothing can be sent to or received from
1496 the connection. Affected file lib/silcutil/silsockconn.[ch].
1497 The checking for disabled socket is checked in the low level
1498 silc_socket_write and silc_socket_read functions.
1500 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Allow only nicknames and channel names that fits into the
1503 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1505 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * When processing JOIN command reply in server check that if
1508 the channel exists in our global list we'll move it the local
1509 list. Affected file silcd/command_reply.c.
1511 * Fixed the check whether client is joined on the channel already
1512 in JOIN command. Affected file lib/silcclient/command.c.
1514 * Fixed the JOIN command reply to check whether the channel
1515 already exists. Affected file lib/silcclient/command_reply.c.
1517 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * Added silc_ske_status_string to map the SKE error numbers
1520 to readable strings. The affected files are
1521 lib/silcske/silcske[_status].[ch].
1523 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Do not show the private channels on the WHOIS channel list
1526 as it is not allowed by the protocol. The affected file is
1529 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Assure that the packet length digged from the actual packet
1532 is something sensible in the silc_packet_decrypt_rest_special
1533 in lib/silccrypt/silcpacket.c.
1535 * Free and NULL the allocated pointer in silc_hmac_alloc if
1536 the HMAC allocation fails. The affected file is
1537 lib/silccrypt/silchmac.c.
1539 * Print the selected security properties to the log files in
1540 the server. Affected file silcd/protocol.c.
1542 * Add SKE's reference counter even if calling the completion
1543 callback manually. Otherwise it goes negative, although it
1544 does not cause any problems. The affected file is
1545 lib/silcske/silcske.c.
1547 * Remove the client entry with short timeout after giving the
1548 KILL command. Affected file lib/silcclient/command.c.
1550 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1551 case all found clients are already disconnected (WHOWAS would
1552 found them) in the server. Affected file silcd/command.c.
1554 * Update the last_receive (time of last data received) to be
1555 updated only when received private or channel message so that
1556 the idle time showed in WHOIS makes more sense.
1558 * Added boolean field `valid' in to the SilcClientEntry in the
1559 client library to indicate whether the entry is valid or not.
1560 This fixes the nickname change bug on channel when changing
1561 the nickname to be same than the old (like nick to Nick) the
1562 nickname formatter doesn't set the new nick anymore to Nick@host.
1563 Affected file lib/silcclient/idlist.[ch].
1565 * Now actually fixed the nickname changing on disconnection.
1566 Added new function silc_change_nick to the Irssi SILC Client.
1567 Affected file irssi/src/silc/core/client_ops.c,
1568 irssi/src/silc/core/silc-nicklist.[ch].
1570 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Check that the public key exists in the GETKEY command before
1573 trying to encode it. Affected file silcd/command.c.
1575 * Print some notifications on received public keys with GETKEY
1576 command in the Irssi SILC Client. Affected files are
1577 irssi/src/fe-common/silc/module-formats.[ch],
1578 irssi/src/silc/core/client_ops.c.
1580 * Use IDENTIFY command to resolve the server information in the
1581 GETKEY command instead of INFO command. Affected file
1582 lib/silcclient/command.c.
1584 * All command reply functions in the client library now calls
1585 the pending command reply callbacks even if an error has
1586 occurred. The server has done this a long time and now it was
1587 time to move the client library to this as well. Now all
1588 errors can be delivered back to the pending command reply
1589 callbacks if necessary. Affected files are
1590 lib/silcclient/command[_reply].[ch].
1592 * Change the nickname on disconnection back to the username
1593 because in reconnect the server will enforce it to it anyway.
1594 Affected file irssi/src/silc/core/silc-servers.c.
1596 * Fixed a config file parsing bug in the Irssi SILC client.
1597 Affected file irssi/src/silc/core/clientconfig.c.
1599 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * When printing the channel mode on JOIN, verify that the
1602 channel key and channel's HMAC are valid. Affected file
1603 irssi/src/silc/core/client_ops.c.
1605 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1607 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1608 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1609 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1611 * Removed channel key rekey task deleting from the function
1612 silc_server_save_channel_key. Affected file silcd/server.c.
1613 Added explicit timeout task context instead that is used to
1614 delete the task if we are registering a new task before the
1615 new task has elapsed.
1617 * When channel key rekey occurs the client library now saves
1618 the old channel key for a short period of time (10 seconds) and
1619 is able to use it in case some is still sending channel
1620 messages encrypted with the old key after the rekey. Affected
1621 file lib/silcclient/[idlist.h|client_channel.c].
1623 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Added check to the silc_server_new_id_real to not accept
1626 new ID if it is the sender's own ID. Affected file is
1627 silcd/packet_receive.c.
1629 * Assure that we do not announce ourself or the one we've
1630 sending our announcements when we're router and are announcing
1631 servers to our primary router. Affected file silcd/server.c.
1633 * Fixed silc_server_command_identify_check_client to assemble
1634 correct WHOIS packet. It send corrupted WHOIS packet and
1635 caused problem with router to router connections. Affected
1636 file silcd/command.c.
1638 Fixed also silc_server_command_whois_check the same way
1639 as for the IDENTIFY command.
1641 * Added new SilcIDListStatus to the server in the SilcIDListData
1642 structure. The status now includes the current status of
1643 the entry (like registered, resolved etc.). Affected file
1644 silcd/idlist.[ch]. Defined a bunch of different status types
1645 as well. This replaced the old boolean registered field as well.
1647 Added resolve_cmd_ident field to the SilcClientEntry structure
1648 too so that if the entry is for example being resolved so
1649 another command may attach to the same pending command reply
1650 without requiring to resolve the same entry again. This concept
1651 should optimize the WHOIS and the IDENTIFY resolving under
1652 heavy load by taking away unnecessary resolving for entries
1653 that are being resolved already.
1655 Added support for adding multiple pending commands for one
1656 command idenfier. Affected file silcd/command[_reply].[ch].
1658 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1659 before deleting the data. Otherwise the hash table will have
1660 freed data in comparison functions. Affected file is
1661 silcd/command_reply.c.
1663 * Fixed silc_idlist_replace_client_id to add the new entry to
1664 the cache with NULL nickname. Otherwise there will be invalid
1665 memory as the nickname after the nickname is freed. Affected
1666 file silcd/packet_receive.c.
1668 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1669 saved into wrong slots because the previous number of entries
1670 was not taken into account. Affected file silcd/idlist.c.
1671 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1673 * If we are router and we receive JOIN notify to a channel that
1674 does not have any users then notified client is marked as the
1675 channel founder, as it is it. The affected file is
1676 silcd/packet_receive.c
1678 * Added to the extended hash table API's table_del_*ext functions
1679 the destructor as argument too, so that the caller can decide
1680 which destructor to use or whether to use destructor at all.
1681 Affected file lib/silcutil/silchashtable.[ch].
1683 * Fixed ID Cache purging. It actually deleted the entries from
1684 the hash table after the data was freed. The hash table ended
1685 up comparing freed memory. The affected file is
1686 lib/silccore/silcidcache.c.
1688 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Fixed Irssi SILC client's KILL command's HELP syntax.
1692 * The USERS command now resolves the detailed user information
1693 if the userinfo field is missing. Affected file is
1694 lib/silcclient/command_reply.c.
1696 * Do not print error in silc_file_read if the read file does
1697 not exist. Just silently return NULL. Affected file is
1698 lib/silcutil/silcutil.c.
1700 * Fixed the silc_log_output to not wine about NULL filename
1701 and to not create some bogus " " filename. Affected file is
1702 lib/silcutil/silclog.c.
1704 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1706 * Fixed various printing bugs on the user interface in the
1707 Irssi SILC Client. Minor changes that were forgotten from
1710 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1712 * Fixed the configure.in.pre and the compilation and distribution
1713 environment to support the new autoconf 2.52. That version is
1714 now required to compile the CVS trunk.
1716 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1718 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1719 to generally parse user@fqdn format strings. Affected file
1720 lib/silcutil/silcutil.c.
1722 * Added nickname_format and nickname_force_format fields to the
1723 SilcClientParams structure. The first one defines the format
1724 for the nicknames that the library will enforce if the receives
1725 multiple same nicknames. The second one is boolean value and
1726 can be used to force the library to always enforce the format
1727 to the nicknames regardles whether there are multiple nicknames
1728 or not. This configurable formatting was employed to flexibly
1729 support accessing multiple nicknames from the user interface.
1730 The userinterface can now set the nicknames to what ever format
1731 they prefer. Affected file lib/silcclient/silcapi.h.
1733 Added function silc_client_nickname_format to the file
1734 lib/silcclient/idlist.c. It performs the nickname formatting.
1736 Added new field `hostname´ to the SilcClientEntry context.
1737 It holds the hostname of the client. Affected file is
1738 lib/silcclient/idlist.h.
1740 * Irssi SILC Client sets the nicknames in nick@hostn format.
1741 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1742 irssi/src/silc/core/silc-core.c.
1744 The WHOIS printing now also shows both the real nickname and
1745 the formatted nickname so that user knows how to access the
1746 user if there are multiple same nicknames cached. Affected
1747 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1748 printing formatting too to take the hostname now as a separate
1749 argument. The Affected file is
1750 irssi/src/fe-common/silc/modules-formats.[ch].
1752 * Changed the silc_client_get_clients_local to accept the formatted
1753 nickname as argument. It accepts the real nickname too but the
1754 formatted nickname can be used to find the true entry from
1755 multiple entries. Affected file lib/silcclient/silcapi.h and
1756 lib/silcclient/idlist.c.
1758 * Added nickname_format_parse field to the SilcClientParams.
1759 It is a callback function provided by the application to parse
1760 the nickname out of the formatted nickname string. The library
1761 calls it to get the nickname from the formatted string. Since
1762 the application generally knows better the format of the nickname
1763 string it parses it instead of the library, even though library
1764 encodes the formatted string. If the callback function is not
1765 provided then the library will use the string as is. The
1766 affected file is lib/silcclient/silcapi.h.
1768 * All the nickname strings passed to the client library in
1769 commands are now expected to be formatted nickname strings.
1770 If the command does not support the formatted nickname string
1771 it will assume that the sent string is the actual nickname.
1772 Affected file lib/silcclient/command.c.
1774 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Added public key authentication support to OPER and SILCOPER
1777 commands in the client library. Affected file is
1778 lib/silcclient/command.c.
1780 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Changed the get_auth_methdod client operation to be asynchronous.
1783 It can be async if the application resolves the authentication
1784 method from the server during the negotiation. Added new
1785 SilcGetAuthMeth completion callback that the application will
1786 call after resolving the authentication method.
1788 Added function silc_client_request_authentication_method that
1789 the application can use to resolve the authentication method
1790 from the server. Added also SilcConnectionAuthRequest callback
1791 that the library will call after the server has replied. The
1792 application can call this function if it does not know the
1793 current authentication method.
1795 Affected files are lib/silcclient/client.c and
1796 lib/silcclient/silcapi.h.
1798 * The Irssi SILC client now automatically resolves the authentication
1799 method incase any configuration information is not present (and
1800 currently there never is). The affected file is
1801 irssi/src/silc/core/client_ops.c.
1803 * Fixed public key authentication from the client library.
1804 Affected file lib/silcclient/protocol.c. Changed also the
1805 protocol specification about the public key authentication in
1806 the connection authentication protocol. The actual data to be
1807 signed is now computed with a hash function before signing.
1809 * Fixed the public key authentication from the server as well.
1810 Affected file silcd/protocol.c.
1812 * Removed the mlock()'s from the memory allocation routines.
1813 Affected file lib/silcutil/silcmemory.c. The ./configure does
1814 not check anymore for the mlock(). Affected file is
1817 * Fixed USERS command in server to allow the execution of the
1818 command for private and secret channels if the client sending
1819 the command is on the channel. Affected file silcd/command.c.
1821 * Fixed silc_client_get_clients_local to return the clients
1822 count correctly. It could return wrong value. Affected file
1823 lib/silcclient/idlist.c.
1825 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1827 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1828 types. The assembler optimizations seemed not to like 64-bit
1829 data types. The assmebler optimizations thus are now enabled
1830 also for BSD systems as opposed to only enable them for Linux.
1832 * Do not check for threads at all on BSD systems. Affected
1833 file configure.in.pre.
1835 * Removed -n and -h options from the Irssi SILC Client since
1836 they are not used in silc.
1838 * Fixed the prime generation to assure that the first digit
1839 of the generated random number is not zero since our conversion
1840 routines does not like number strings that starts with zero
1841 digit. If zero digit is seen the random number is regenerated.
1842 This caused some corrupted RSA keys when the zero first digit
1843 was met. Affected file lib/silcmath/silcprimegen.c.
1845 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1847 * Fixed WIN32 configuration in the ./configure script.
1848 Fixed to include xti.h on environments that has it.
1849 Patches by Carsten Ilchmann and andrew.
1851 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Changed the silc_id_create_client_id to be collision
1854 resistant. It is now assured that there cannot be created
1855 two same client ID's. I suspect that some weird bugs in
1856 the server were actually caused by duplicate Client IDs.
1857 Affected file silcd/serverid.[ch]. A router receiving
1858 new ID now also assures and informs the sending server
1859 if the ID caused collision.
1861 * Changed the silc_id_create_channel_id to also assure that
1862 there are no collisions.
1864 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Statement about ignoring the Mutual Authentication flag when
1867 performing rekey with PFS was a bit misleading. It is ignored
1868 if it was set in the initial negotiation, it cannot be even
1869 set in the rekey. Fixed in the ke-auth draft. Started the
1870 new versions of the protocol drafts in the doc/.
1872 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Fixed a bug in silc_client_command_identify_save when saving
1875 new channel information. The channel name was no duplicated
1876 and caused crash on exit. Affected file is
1877 lib/silcclient/command_reply.c.
1879 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Fixed the getkey command handling in the server. Send just
1882 empty OK reply to the sender if the key could not be fetched
1883 (but everything else was ok, like the key just was not available).
1884 Changed the public key parameter to optional in the protocol
1885 specs so that empty OK reply can be sent. Affected file
1888 Added a message to Irssi SILC client to tell to user if the
1889 server did not return a public key.
1891 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Fixed a channel key regeneration bug. It registered new
1894 timeout tasks exponentially until all system resources were
1895 used. Affected file silcd/server.c.
1897 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1899 * Added the SILC Document generator to the scripts/silcdoc.
1900 It can be used to generate the Toolkit Reference Manual out
1901 of the source tree. Internally it will also use the RoboDoc
1902 generator now imported in util/robodoc.
1904 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Added couple of return's in rekey protocol if error orccurred
1907 during the protocol. The execution must be terminated.
1908 Affected file silcd/protocol.c. Also, terminate the protocol
1909 always with timeout.
1911 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * The client's Client ID was created initally from the wrong
1914 nickname (it could have been in format nick@host) in the
1915 silc_server_new_client. Affected file silcd/packet_receive.c
1917 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1919 * Added some SILC_LOG_ERROR's to various error conditions
1920 if client could not be added to ID cache. Affected files
1921 silcd/packet_receive.c and silcd/server.c.
1923 * When client's sock->user_data is freed, NULL also the
1924 client->router and client->connection pointers. Added check
1925 for these pointers being NULL to various places around the
1926 code. Affected file silcd/server.c.
1928 * Added client->data.registered == TRUE checks to various
1929 places around the code to assure that unregistered client's
1930 are not handled when it is not allowed. Affected file
1933 * Added `bool registered' fields to all
1934 silc_idlist_[server|client]_get_* routines to indicate whether
1935 the fetched client needs to be registered or not. Affected
1936 file silcd/idlist.[ch].
1938 * Add your own entry as registered to the ID cache in the
1939 server. Affected file server.c.
1941 * Fixed a bug in silc_server_new_server. The SilcServer was
1942 set as the new server's context instead of SilcServerEntry.
1943 This naturally caused some weird bugs.
1945 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Do not delete the channel rekey task when adding it
1948 for in silc_server_create_channel_key.
1950 * Changed the silc_server_create_channel_key to return
1951 TRUE or FALSE to indicate the success of the channel key
1954 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Fixed MSVC++ project files and added missing files to
1957 Makefiles under win32/.
1959 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Do not add TCP_NODELAY flag if the operating system
1962 does not have it defined. Affected files are
1963 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1965 * Fixed buffer overflow from Irssi SILC Client. Affected
1966 file irssi/src/fe-common/core/themes.c.
1968 * Fixed double free in client library in the file
1969 lib/silcclient/client.c when disconnecting from server.
1971 * Applied double free patch from cras to Irssi SILC client.
1972 Affected files irssi/src/core/[modules/expandos].c
1974 * Fixed the disconnection handling to Irssi SILC Client.
1975 The application must call silc_client_close_connection
1976 in ops->connect client operation in case of failure of
1977 the connection. Affected file is
1978 irssi/src/silc/core/client_ops.c.
1980 * Do not set sock->protocol to NULL in the function
1981 silc_client_close_connection after executing the protocol's
1982 final callback since the sock might not be valid anymore.
1983 Affected file lib/silcclient/client.c.
1985 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Do not enable SILC_THREADS if the linking with libpthread
1988 did not happen. Affected file configure.in.pre.
1990 * Added notion to protocol specification that server must
1991 verify the sent authentication payload with CMODE when
1992 setting the channel founder key. Implemented it to the
1993 server. Affected file silcd/command.c.
1995 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Added _EXTRA_DIST SILC distribution variable to the
1998 distributions file. It is used to conditionally add extra
1999 files or directories to the specific distribution. Affected
2000 files ./prepare, Makefile.am.pre and distributions.
2002 Removed the `_' from the start of the distribution names.
2005 * Added README.WIN32 for instructions to compile the Toolkit
2008 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Fixed a double free in disconnection in the server. Affected
2011 file is silcd/server.c.
2013 * Fixed the lib/silcske/groups.c to work now also with GMP
2014 MP library. The string conversion did not work when using
2015 specific base and the base is indicated in the string as well.
2017 * Created win32/ directory which now includes MSVC++ specific
2018 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2019 It will appear only in the toolkit distribution
2021 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * Changed the key material distribution function in case when
2024 the hash output is too short. The data is now concatenated
2025 a bit differently than it used to. Made the change to the
2026 SKE protocol specification.
2028 * Added better GMP detection to configure.in.pre. A patch
2031 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Fixed a minor bug in SKE that might cause some problem on
2034 some platforms. Affected file lib/silcske/silcske.c.
2036 * Added the cookie checking for initiator in the SKE. It checks
2037 that the responder returns the sent cookie unmodified. The
2038 affected file is lib/silcske/silcske.c. Added new SKE
2039 error type INVALID_COOKIE that can be sent during the
2040 negotiation. Fixed some memory leaks as well.
2042 * Added the "invalid cookie" error message to Irssi SILC client's
2045 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Added `task_max' field to the SilcClientParams to indicate
2048 the maximum tasks the scheduler can handle. If set to zero,
2049 default values are used. Affected file lib/silcclient/silcapi.h.
2051 * Fixed memory leaks in silc_client_close_connection. Affected
2052 file lib/silcclient/client.c.
2054 * Added silc_client_del_client_entry to client library to free
2055 all memory of given client entry. Affected file is
2056 lib/silcclient/idlist.[ch].
2058 * Added new functions silc_client_del_channel and
2059 silc_client_del_server to delete channel and server entries.
2060 Affected file lib/silcclient/[silcapi.h/idlist.c].
2062 * Removed silc_client_del_client_by_id from silcapi.h.
2064 * Fixed the INFO command to return the server's own info
2065 correctly when querying by Server ID. Affected file is
2068 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Removed the non-blocking settings in WIN32 code in the
2071 silc_sock_[read/write] and added SleepEx instead. Affected
2072 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2073 of input data is now checked with FIONREAD and ioctlsocket.
2075 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Call silc_schedule_task_del_by_context in the
2078 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2079 Affected file lib/silccore/silcprotocol.c.
2081 * Call silc_protocol_cancel for active protocols in the
2082 silc_server_close_connection if the funtion
2083 silc_server_free_sock_user_data has not been called.
2084 Affected file silcd/server.c.
2086 * Generic tasks cannot be deleted using the del_by_fd
2087 task deleting function since generic tasks does not match
2088 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2090 * Added a notion to SILCOPER help file that the SILCOPER works
2091 only on router server, not on normal server.
2093 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Added for WIN32 support for the new scheduler as well.
2096 Affected file lib/silcutil/win32/silcwin32schedule.c.
2098 * Fixed the SHA1 implementation to work on various platforms.
2100 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2103 API. It is part of the scheduler now. Everything else is
2104 as previously but some functions has changed their names.
2105 Checkout the lib/silcutil/silcschedule.h for the interface.
2106 Updated all applications to use the new interface. Affected
2107 files are lib/silcutil/silcschedule.[ch].
2109 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Found a bug in the SKE implementation. The HASH value,
2112 specified by the protocol, was not computed correctly. The
2113 public key of the responder was not added to the computation
2114 even though it is mandatory. Affected file lib/silcske/silcske.c.
2115 This unfortunately causes incompatibilities with older
2116 clients and servers.
2118 * Added WIN32 specific network init and uninit functions:
2119 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2120 the Winsock2. Affected file lib/silcutil/silcnet.h and
2121 lib/silcutil/win32/silcwin32net.c.
2123 * Set the socket always to nonblocking mode on WIN32 after
2124 reading data or writing data. Affected file is
2125 lib/silcutil/win32/silcwin32sockconn.c.
2127 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Fixed various compilation problems under WIN32. Affected
2130 files lib/silcutil/win32/silcwin32thread.c and
2131 lib/silcutil/win32/silcwin32schedule.c.
2133 * Removed all _internal.h #includes from public header
2134 files. Internal headers must never be included from
2137 Removed also the lib/silcske/payload_internal.h file.
2139 * All include files that may be needed (public and some others
2140 included by the public headers) by application developers are
2141 now copied to the ./includes directory. It does not copy any
2142 internal headers. Affected file Makefile.defines.pre and all
2143 Makefile.am's under lib/ and subdirs.
2145 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2147 * Do not change the ~/.silc directory's permissions automatically.
2148 Affected file irssi/src/silc/core/clientutil.c.
2150 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2152 * Do not cancel the protocol in silc_server_close_connection
2153 it might cause recursion. Now cancelled in the function
2154 silc_server_free_sock_user_data. Affected file silcd/server.c.
2156 * Fixed the silc_server_remove_clients_by_server to regenerate
2157 the channel keys correctly finally. Added also new function
2158 silc_server_remove_clients_channels to actually do it.
2159 Affected file silcd/server.c.
2161 * Fixed the silc_server_new_channel to not crash by giving
2162 wrong router to the new channel. Affected file is
2163 silcd/packet_receive.c.
2165 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2168 which is given as argument to the silc_client_alloc now.
2169 It can be used to configure the client and set various parameters
2170 that affect the function of the client.
2172 * The USERS command in server did not check whether the channel
2173 is private or secret. Affected file silcd/command.c.
2175 * Added new argument to the USERS command in protocol specification.
2176 The USERS command now can take the channel name as argument
2177 as well. Added support for this in client and server and
2178 updated the protocol specs.
2180 * Completed the GETKEY command in client. It can be now used
2181 to fetch also servers public key not only some clients.
2182 Affected files lib/silcclient/command[_reply].c.
2184 * Added silc_client_get_server to return server entry by the
2185 server name. Affected files lib/silcclient/silcapi.h and
2188 * Redefined the IDENTIFY command in protocol specification to be
2189 more generic. It now can be used to query information about
2190 any entity in the SILC Network, including clients, servers and
2191 channels. The query may be based either the entity's name
2192 or the ID. Added support for this in both client and server.
2194 Affected files silcd/command.c and lib/silcclient/command.c
2195 and command_reply.c.
2197 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2198 the _from_client and _from_server functions. Affected file
2201 * Added silc_client_get_channel_by_id_resolve to the file
2202 lib/silcclient/silcapi.h to resolve channel information by
2203 its ID. Added also silc_client_get_channel_by_id that
2204 does not resolve it from the server.
2206 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Added SilcServerEntry context into the client library
2209 to represent one server. The INFO command now allocates
2210 these to save the resolved server info. For now on the
2211 client library will also keep information about servers,
2212 connected and resolved with INFO.
2214 The INFO command now allocates the SilcServerEntry context
2215 and saves the server info there. The COMMAND_REPLY in
2216 the INFO now returns the parameters to application in
2217 same order as defined in the protocol specification.
2219 The entries are cached in the client->server_cache.
2221 * The INFO command is now issued after received the Client ID
2222 from the server. Affected file lib/silcclient/client.c.
2224 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2225 to the application as the mode changer might be server.
2226 It is guaranteed that NULL is not returned anymore to the
2227 application. Affected file lib/silcclient/client_notify.c.
2229 The ID Type is now also passed to the application so that
2230 it can check whether the returned entry is SilcClientEntry
2233 Added new function silc_client_get_server_by_id to return
2234 the server entry by ID. Affected files are the
2235 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2237 * Do not create the channel in the Irssi SILC Client when issuing
2238 the JOIN command but when received the sucessful JOIN command
2239 reply. Otherwise the channel might get created even though we
2240 could not join it. The Affected file is
2241 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2243 * Fixed a channel joining bug in router. The router must also
2244 check the channel modes, invite and ban lists etc. when serving
2245 the JOIN command sent by normal server. Affected file is
2246 silcd/command.c. The router now resolves the client's
2247 information from the server who sent the JOIN command if it
2248 does not know it, and processes the JOIN command only after
2251 * Changed the SilcCommandCb to take new argument; void *context2.
2252 Affected file lib/silccore/silccommand.h
2254 The second argument in the command callbacks in the server now
2255 includes the SilcServerCommandReplyContext if the command was
2256 called as pending command callback from the command reply.
2257 Otherwise it is NULL. When called as pending the status of the
2258 command reply will be checked and if it was erronous the
2259 error will be sent to the original sender of the command.
2260 This way the client always receives the error messages even
2261 though the server was actually the one who received the error
2262 when it resent the command to router, for example. Affected
2263 files silcd/command[_reply].[ch].
2265 * Fixed sending WHOWAS command's error message to client if
2266 the requested client could not be found. It was missing.
2269 * Changed the CMODE and CUMODE commands reply arguments in the
2270 protocol specification. The Channel ID is now sent in both
2271 of the commands to identify the channel. Implemented this
2272 new feature to the client and server. Affected files
2273 lib/silcclient/command_reply.c and silcd/command.c.
2275 * Made better checks for invite and ban lists in the JOIN
2276 command in server. Affected file silcd/command.c.
2278 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * The server now performs the incoming host IP/DNS lookup
2281 using the silc_socket_host_lookup and thus does not block
2282 the server anymore. Affected file silcd/server.c.
2284 * Completed the multi-thread support for SILC Scheduler in
2285 the lib/silcutil/silcschedule.c.
2287 * Fixed the configure.in.pre to detect the pthread correctly
2290 * Fixed a deadlock in silc_task_queue_wakeup in the file
2291 lib/silcutil/silctask.c.
2293 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2295 * Added new function silc_schedule_wakeup that is used in
2296 multi-threaded environment to wakeup the main thread's
2297 schduler. It needs to be used when a thread adds a new task
2298 or removes a task from task queues. After waking up, the
2299 scheduler will detect the task queue changes. If threads
2300 support is not compiled in this function has no effect.
2301 Implemented the wakeup mechanism to both Unix and WIN32
2302 systems. Affected files are lib/silcutil/silcschedule.[ch],
2303 lib/silcutil/unix/silcunixschedule.c and the
2304 lib/silcutil/win32/silcwin32schedule.c.
2306 * Added new function silc_task_queue_wakeup to wakeup the
2307 scheduler by the specified task queue. Affected file
2308 lib/silcutil/silctask.[ch].
2310 * The silc_socket_host_lookup_start now wakes up the scheduler
2311 after adding the timeout task. Affected file is
2312 lib/silcutil/silcsockconn.c.
2314 * The silc_socket_host_lookup is synchronous now if the threads
2315 support is not compiled in. However, the callback is still
2316 called asyncronously through the scheduler, anyway. Affected
2317 file lib/silcutil/silcsockconn.c.
2319 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Added new function silc_socket_host_lookup to perform
2322 asynchronous IP and FQDN lookups for the socket connection.
2323 Affected files lib/silcutil/silcsockconn.[ch].
2325 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2327 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2328 that may or may not compile the mutex support in.
2330 Changed the silc_mutex_alloc interface. It allocates the
2331 mutex now to the sent pointer and returns TRUE or FALSE.
2333 Affected file lib/silcutil/silcmutex.h.
2335 * Wrote the SILC Task Queue interface to support multi-threads.
2336 Affected file lib/silcutil/silctask.[ch].
2338 * Wrote the SILC Scheduler to support multi-threads. Affected
2339 file lib/silcutil/silcschedule.c.
2341 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2343 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2344 in lib/silcutil/win32/.
2346 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Defined SILC Mutex API and SILC Thread API and implemented
2349 them for Unix. Affected files are
2350 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2351 lib/silcutil/unix/silcunixmutex.c and
2352 lib/silcutil/unix/silcunixthread.c.
2354 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Fixed the silc_server_remove_clients_by_server's channel
2357 key re-generation. The hash table handling was incorrect
2358 and would not work with many channels. Affected file is
2361 * Fixed some memory leaks around the server code.
2363 * Rewrote the silc_server_get_users_on_channel to support IPv6
2364 based Client ID's. Affected file silcd/server.c.
2366 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2367 specification. However, a separate document must be written
2368 to define the detailed signing procedure and the payload
2369 associated with the flag. Defined the flag to the
2370 lib/silccore/silcchannel.h as well.
2372 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Changed the dynamic tables to static size tables in the
2375 lib/silccrypt/silchmac.c.
2377 * Removed GCC dependencies from the code. A patch by cras.
2379 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Do not show the error "Error receiving packet bla bla"
2382 in server if it really was not an error (-2 means that reading
2383 is pending). Affected file silcd/server.c.
2385 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Fixed a possible crash in silc_server_remove_clients_by_server
2388 in silcd/server.c. Fixed there also some memory leaks.
2390 * Fixed the silc_idlist_replace_client_id. It could replace
2391 wrong key in the hash table. Affected file silcd/idlist.c.
2393 * Do not check whether there are global users on the channel
2394 if the channel->global_users is FALSE. Affected functions
2395 silc_server_remove_from_one_channel and
2396 silc_server_remove_from_channels in silcd/server.c. Also,
2397 do not check if the removed client is local as we can be
2398 sure that global client was not removed from the channel
2399 and checking for global users is not needed.
2401 * The silc_server_remove_clients_by_server now re-generates
2402 the channel keys correctly for those channels that had
2403 clients removed from them. Affected file silcd/server.c.
2405 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Found the reason of random crashes in the server. We weren't
2408 ignoring the SIGPIPE signal (which can be sent in write())
2409 and it crashed the server. Affected file silcd/silcd.c.
2411 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Assure that sock->user_data is not NULL in the function
2414 silc_server_packet_send in silcd/packet_send.c.
2416 * Disconnect the remote connection if it could not be added
2417 to any ID lists in the server. The affected file is
2420 * Check in silc_server_packet_send[_real/dest] that the
2421 socket is not disconnecting and ignore the data if it is.
2422 Affected file silcd/packet_send.c.
2424 * Define inline to __inline on native WIN32 compilation.
2425 Affected file includes/silcwin32.h.
2427 * Added some explicit type casts for inline code since MSVC
2428 require them. Affected files lib/silcutil/silcbuffer.h,
2429 lib/trq/silcdlist.h and lib/trq/silclist.h.
2431 * Print warning in log files from now on if the packet
2432 decryption fails. Affected file silcd/server.c.
2434 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Changed the `say' client operation's interface to accept
2437 new `type' argument to indicate the type of the message sent
2438 by the library. The application may filter the library's
2439 messages according the type. The affected file is the
2440 lib/silcclient/silcapi.h.
2442 * Added two new functions to lib/silcclient/silcapi.h:
2443 silc_client_del_client and silc_client_del_client_by_id.
2444 Affected file lib/silcclient/idlist.c.
2446 * Moved the clientincludes.h from includes/ to silc/ and
2447 serverincludes.h from includes/ to silcd/.
2449 * The modes for the CMODE and CUMODE are now passed as
2450 uint32 for application with COMMAND_REPLY. The affected
2451 file is lib/silcclient/command_reply.c.
2453 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * /WHOIS without arguments shows client's own information.
2456 Affected file lib/silcclient/command.c.
2458 * Changed PING to not accept any arguments. The specs
2459 says that client can ping only the connected server so
2460 requiring an argument is not needed. Affected file is
2461 lib/silcclient/command.c.
2463 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Fixed a fatal bug in private message sending and reception
2466 encryption and decryption when using private message keys.
2467 The implementation was incorrect and did not follow the
2468 specification. It causd that some of the message were
2469 lost since it did not use the sending and receiving keys
2470 as the protocol suggests. This has been fixed and will cause
2471 incompatibilities with older clients when sending private
2472 message encrypted with private message keys. Affected files
2473 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2474 and various other in Irssi SILC Client.
2476 Added `responder' boolean argument to the functions
2477 silc_client_add_private_message_key[_ske] to indicate when
2478 the key is added as responder or initiator of the key
2481 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Removed the silc_ske_check_version function and created
2484 a SilcSKECheckVersion callback. Added also a function
2485 silc_ske_set_callbacks that is now used to set all SKE
2486 callbacks. The callback functions are not given to
2487 the SKE functions anymore, but this function is used to
2490 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2492 * Added `silc_version' argument to the silc_client_alloc
2493 to define the version of the application for the library.
2494 The library will use the version string to compare it
2495 against the remote host's (usually a server) version
2496 string. Affected file lib/silcclient/silcapi.h
2498 * Added the KE protocol context to Key Agreement context
2499 in client library so that we can abort the SKE if it
2500 is in process when we get timeout. Affected file is
2501 lib/silcclient/client_keyagr.c.
2503 * Do not resolve the client ID forever if it returns in the
2504 first time that such client does not exist. This was done
2505 for example with private message. Affected file is
2506 lib/silcclient/client_prvmsg.c.
2508 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Do not add regex.h for WIN32. The affected file
2511 includes/silcincludes.h.
2513 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2514 not work yet 100%. It generates the DLL's automatically
2515 when compiling with --with-win32 under cygwin.
2517 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * lib/contrib/regex.c is not compiled on WIN32.
2521 * Added silc_net_get_socket_opt function to the
2522 lib/silcutil/silcnet.h.
2524 * Added includes/silcwin32.h for WIN32 specific includes
2527 * Do not use ptime structure or any of the posix process
2528 functions on WIN32 in lib/silccrypt/silrng.c.
2530 * Added silc_gettimeofday to provide generic function
2531 for struct timeval on all platforms. Added the function
2532 to lib/silcutil/silcutil.h.
2534 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2537 library as they clearly belong there. As a plus side we
2538 can make the actual socket connection routines platform
2541 Added also new generic function silc_socket_read and
2542 silc_socket_write (that used to be silc_packet_[read/write].
2543 The implementation of these are platform specific.
2545 * Added WIN32 specific routines of silc_socket_[read/write]
2546 to lib/silcutil/win32/silcwin32sockconn.c.
2548 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Added preliminary support for native WIN32 compilation under
2551 cygwin (using the -mno-cygwin option for GCC) to the
2552 ./configure.in.pre. The --with-win32 now prepares the
2553 compilation for native WIN32.
2555 * Rewrote the SILC Scheduler interface in the file
2556 lib/silcutil/silcschedule.h. The scheduler is now context
2557 based and does not have anymore any global static scheduler.
2558 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2559 and created lib/silcutil/win32 directory for WIN32 based
2562 * Added Unix specific network routines to the
2563 lib/silcutil/unix/silcunixnet.c and the old
2564 lib/silcutil/silcnet.c includes now only generic routines.
2566 Added WIN32 specific network routines to the
2567 lib/silcutil/win32/silcwin32net.c.
2569 * Added Unix specific utility functions from the
2570 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2572 * Added WIN32 SILC Scheduler to the file
2573 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2576 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Do not handle JOIN notify in the server if the target client
2579 is not registered (idata->registered == FALSE). The affected
2580 file is silcd/packet_receive.c.
2582 * Update the nickrec->founder in event_cumode in the Irssi SILC
2583 client. Affected file irssi/src/silc/core/silc-channels.c.
2585 * Fixed the CUMODE_CHANGE notify handling in the server when
2586 server and router are announcing their clients on channels.
2587 Now the mode changes are saved and notified correctly. The
2588 affected file is /silcd/packet_receive.c.
2590 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2591 They really did not replace the cache entry in the ID Cache.
2592 Now they do that. Affected file silcd/idlist.c.
2594 * Fixed the KICK notify handling in the Irssi SILC client to
2595 update the channel records so that the kicked client does not
2596 appear to be on the channel. The affected file is
2597 irssi/src/silc/core/silc-channels.c.
2599 * Always update the conn->current_channel when executing command
2600 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2602 * Fixed the KILL notify handling in Irssi SILC client to remove
2603 the killed client on all channels.
2605 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Fixed the silc_parse_command_line to remove extra spaces
2608 from the start and end of the arguments. Affected file is
2609 lib/silcutil/silcutil.c.
2611 * Cancel and free any active protocol in the function
2612 silc_server_close_connection. Affected file silcd/server.c.
2614 * Cancel and free any active protocol in the function
2615 silc_client_close_connction. Affected file is
2616 lib/silcclient/client.c.
2618 * Do not execute the KILL command for clients that are in
2619 history (ie. they are not in the network). Affected file is
2622 * Fixed KILL notify handling, client does not crash anymore.
2623 Affected file irssi/src/silc/core/silc-channels.c.
2625 * Reduced the default packet buffer size from 2048 to 1024 in
2626 lib/silccore/silcpacket.c.
2628 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2629 counter to the SKE context that is incresed when the SKE library
2630 performs async operation outside the library. If the outside
2631 process frees the SKE context and FREED status will be set
2632 and the library will detect after the sync operation that the
2633 libary is freed. The affected files are
2634 lib/silcske/silcske[_status].[ch].
2636 * Resolve the client entry information in the function
2637 silc_client_channel_message to assure that NULL pointer is not
2638 passed as client entry to the application. */
2640 * Fixed the task timeout calculation to assure that there is
2641 never negative timeouts. The affected file is
2642 lib/silcutil/silcschedule.c.
2644 * Fixed the channel user mode notification sending in server.
2645 It was sent point-to-point to the router (or to server by router)
2646 but it needs to be destined to a channel. The routines now
2647 supports sending the channel user mode notifys to the channels
2648 when announcing clients and channels. Affected files are
2649 silcd/server.c and silcd/packet_receive.c.
2651 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2652 It did not actually replace the old channel entry in the cache.
2653 Affected file lib/silcclient/client_notify.c.
2655 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Fixed a possible crash in silc_packet_send_prepare. It now
2658 assures always that there is enough space in the buffer and
2659 at the tail area of the buffer (for MAC).
2661 Fixed the inbound buffer reallocation in silc_packet_read.
2662 It was old code and did not handle the reallocation correctly.
2665 The affected file is lib/silccore/silcpacket.c.
2667 * Fixed buffer overflow in silc_parse_nickname in the file
2668 lib/silcutil/silcutil.c.
2670 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * make install generates new server keys only if there is not
2675 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2677 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2678 Added check that if the NOREPLY is set then we will not send
2679 the away message. This avoids infinite loop of away messages
2680 if both clients are away. The affected file is
2681 lib/silcclient/client_prvmsg.c.
2683 * Fixed client crash if /NICK was given without arguments.
2684 Affected file lib/silcclient/command.c.
2686 * Server does not send the invite list in INVITE command back
2687 to the client if the list was not altered. Added this notion
2688 to the protocol spec as well. Affected file silcd/command.c.
2690 Fixed possible crash in INVITE command by checking the
2691 value of silc_server_get_client_route command.
2693 * Fixed the INVITE notify type handling. The arguments are now
2694 taken in correct order and client does not crash. The affected
2695 file is irssi/src/silc/core/silc-channels.c.
2697 Removed the "Inviting xxx to channel" message from the
2698 client library away and let the application handle it.
2699 Affected file lib/silcclient/command.c. Added that message
2700 to Irssi SILC client's message formats.
2702 * Fixed CMODE command crash in client. It now checks the
2703 amount of arguments correctly and does not crash. The affected
2704 file is lib/silcclient/command.c.
2706 * Do not create new channel automatically in silc_channels_join
2707 but check whether the channel by that name already exists.
2708 Affected file irssi/silc/core/silc-channels.c.
2710 * Do not send the SERVER_SIGNOFF to router if the disconnected
2711 entity was the router. Affected file silcd/server.c.
2713 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2714 SILC client as it was missing from there.
2716 Added the handling of the KICK notify to the Irssi SILC client
2717 as it was missing. Added "you have been kicked" message to
2718 Irssi SILC client's message modules formats.
2720 Added the handing of the KILL notify to the Irssi SILC client
2721 as it was missing. Added the kill message module formats
2724 The affected file is irssi/src/silc/core/silc-channels.c.
2726 * The router did not save the channel mode the server announced.
2727 Affected file silcd/packet_receive.c.
2729 * Fixed a possible crash in INFO command in server. If the
2730 server did not provide the server info it crashed. Affected
2731 file silcd/command.c.
2733 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Fixed the GETKEY command in the server to check also the
2736 global list. Otherwise the GETKEY would not work correctly
2737 in normal SILC server. Affected file silcd/command.c.
2739 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Fixed GETKEY crash, it crashed if the command did not succseed.
2743 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2746 is now real and not just an macro interface to GMP.
2748 Removed the entire GMP from the source tree and imported new
2749 NSS MPI library instead. Reason for removing GMP is that it is
2750 extremely large and compiles extremely slow. The NSS MPI
2751 is only a few files and compiles in less than 10 seconds.
2752 The speed is also about the same as GMP. The MPI is imported
2753 to lib/silcmath/mpi.
2755 If the system has GMP installed we will still use the GMP.
2756 If it is not then the NSS MPI will be compiled.
2758 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Merged a long nickname (127 characters long) crash bugfix from
2761 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2763 * Merged a freed memory reference bugfix from Irssi CVS tree.
2764 Affected file irssi/src/core/commands.c.
2766 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Added the server's public key sving and verification to the
2769 server when performing the SKE. This was missing and the
2770 remote server's (or router's) public key was accepted without
2771 checking whether we have it previously or trust it at all.
2772 Affected file silcd/protocol.c.
2774 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2776 * Check in the silc_server_timeout_remote if protocol is active
2777 and make sure that the protocol's final callback is called so
2778 that all memory if freed. Affected file silcd/server.c.
2780 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * silc_server_whois_send_reply crashed the server if the nickname
2783 was 127 characters long. Affected file silcd/command.c.
2785 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Added sanity check to the silc_server_new_client. If the hostname
2788 is provided inside username then check that the provided hostname
2789 really is the same as the resolved one. If the hostname was not
2790 resolved then check it from the public key. Affected file is
2791 silcd/packet_receive.c.
2793 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2794 if the server disconnected us and the connection is not valid
2795 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2797 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2798 the library to the lib/silcutil/silcutil.[ch].
2800 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2802 * Close log file after open. Affected file
2803 lib/silcutil/silclog.c.
2805 * Check whether sock == NULL in silc_client_send_packet and return
2806 if it is. Affected file lib/silcclient/silcclient.c.
2808 * Check rec->entry == NULL in the Irssi SILC Client before
2809 sending the channel message. Affecte file is
2810 irssi/src/silc/core/silc-servers.c.
2812 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2814 * Merged a splitted window bugfix from Irssi CVS tree. The
2815 affected file is irssi/src/fe-text/textbuffer-view.c.
2817 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2818 It did not print nickname.
2820 * Improved the distributions system a bit.
2822 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2824 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2825 irssi/src/fe-text/gui-window.c.
2827 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2828 to in-active server. The affected file is
2829 irssi/src/silc/core/client_ops.c.
2831 * Resolve the client in USERS command reply if the entry does
2832 not have username resolved. The affected file is
2833 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2834 command to WHOIS command to really resolve stuff. The USERS
2835 is not used any more in any critical section so WHOIS can
2836 be used even though it might be slower than IDENTIFY.
2838 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2841 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Changed the protocol API a bit more consistent in the
2844 lib/silccore/silcprotocol.[ch].
2846 * Changed the following headers to ROBODoc format:
2848 lib/silccore/silcpayload.h
2849 lib/silccore/silcprotocol.h
2850 lib/silccore/silcsockconn.h
2852 All core library headers are now formatted.
2854 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Fixed a bug in Irssi SILC client; do not show that you are
2857 server/router operator if you really are not. Affected file is
2858 irssi/src/silc/core/client_ops.c.
2860 * Renamed silc_command_free_payload to silc_command_payload_free.
2861 Affected file lib/silccore/silccommand.h
2863 * Added silcmath.h to include the prototoypes of various routines
2864 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2867 * Changed the following headers to ROBODoc format:
2869 lib/silccore/silcchannel.h
2870 lib/silccore/silccommand.h
2871 lib/silccore/silcid.h
2872 lib/silccore/silcidcache.h
2873 lib/silccore/silcmode.h
2874 lib/silccore/silcnotify.h
2875 lib/silccore/silcpacket.h
2876 lib/silcmath/silcmath.h
2878 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2880 * Added checking to the server code not to start the server if
2881 ciphers and stuff are not configured properly. Affected files
2882 silcd/serverconfig.[h] and silcd/server.c.
2884 * Changed the layout of the header files of the public interfaces
2885 in the SILC libraries. The new layout supports ROBODoc
2886 documentation tool (and some others) so that it is easy to create
2887 a library reference manual. All the other headers and source
2888 code must still follow the CodingStyle document. Also source
2889 code must not include these ROBODoc stuffs, only the headers.
2890 Furthermore, all public interface headers must now be named
2891 by using `silc' prefix, example: silcapi.h, silccipher.h.
2892 Some files were renamed due to this. All the other headers
2893 must not be used as public interfaces. I will update the
2894 CodingStyle document later. Changed following headers, so far:
2896 lib/silcclient/silcapi.h
2897 lib/silccore/silcauth.h
2898 lib/silccore/silcprivate.h
2899 lib/silccrypt/silcdh.h
2901 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Removed silc_client_packet_send_flush from the client library
2906 as it is not needed. Affected file lib/silcclient/client.[ch].
2908 * Added printing of message of unresolved authentication method
2909 to the Irssi SILC client. Added it to the module formats.
2910 Removed the same message from the client library.
2912 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Added new distribution feature, DISTLABEL. Every distribution
2915 can define own preprocessor label that can be used in the
2916 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2917 file distributions, acconfig.h.pre and prepare.
2919 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added Makefile.defines_int to include the actual definitions
2922 for Makefile.defines.in. Tested the new distribution system,
2923 created distributions and tested installation.
2925 * Added AWAY message printing to the Irssi SILC client. Added
2926 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2928 * Added SCONNECT command to call the SILC's CONNECT command.
2929 Cannot use CONNECT directly since Irssi uses that internally.
2930 Affected file irssi/src/silc/core/silc-servers.c.
2932 Added ACTION local command. It is same as ME command but takes
2933 the channel as mandatory argument.
2935 Rewrote some of the Irssi's help files to suite for SILC
2938 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Added Makefile.defines[.in] that should for now on be included
2941 in all Makefile.am file in the source tree. That file includes
2942 all common compilation definitions for SILC source tree.
2944 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Minor changes to the ./prepare script to change the package
2947 name according the distribution name to the configure.in.
2949 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Created new distribution system. Added file `distributions'
2952 that defines all the distributions that can be created out of
2953 the SILC source tree. The ./prepare script now reads that
2954 file to determine how to prepare the distributions. The
2955 first argument to the ./prepare is the name of the distribution
2956 and second is the version of the distribution. If given
2957 without arguments it creates the default (toolkit) distribution
2958 with the default version (defined in ./prepare).
2960 All Makefile.am files that are subject to the distributions
2961 are now named as Makefile.am.pre. These are ./Makefile.am
2962 and lib/Makefile.am. Others may be changed later.
2964 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2966 * Added invite list, ban list, some key management and connection
2967 error message printing to module formats in the Irssi SILC client.
2969 * Added new silc_client_set_away_message to set the away message
2970 that is back to the person who sent private message. The
2971 affected file lib/silcclient/silcapi.h and the
2972 lib/silcclient/client_prvmsg.c.
2974 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Fixed the private message sending in the Irssi SILC client,
2977 added local command KEY to the Irssi SILC client.
2979 Added key management and key agreement message formats to the
2980 irssi/src/fe-common/silc/module-formats.[ch].
2982 Added USERS (alias WHO) printing, server/router operator
2983 indication and LIST command printing to the module formats.
2985 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Fixed channel joining notify handling, cumode notify handling
2988 from Irssi SILC client.
2990 * Added SILC specific module-formats to the Irssi SILC client so
2991 that SILC specific message hilighting, colors etc is possible.
2992 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2994 Added channel mode, channel user mode, actions, notices,
2995 whois and whowas printing to the the module-formats.c.
2997 * Fixed a bug in channel deletion in the server. The channel
2998 is not left to the cache even if the channel founder auth mode
2999 is set when there are no users anymore on the channel. Affected
3000 file silcd/server.c.
3002 * The silc_net_localhost now resolves the entire hostname including
3003 the domain name. Affected file lib/silcutil/silcnet.c.
3005 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Changed the ask_passphrase client operation to be ascynchronous.
3008 It has now a completion callback and a context that the
3009 application must call after it has got the passphrase from
3010 the user. Affected files lib/silcclient/silcapi.h,
3011 lib/silcclient/protocol.c, lib/silcclient/command.c and
3014 Added SilcAskPassphrase callback that the application calls
3015 to deliver the passphrase to the library.
3017 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3018 The public key verification and especially a certificate
3019 verification is asynchronous procedure.
3021 Added new SILC_SKE_STATUS_PENDING status to indicate the
3022 request is pending and a callback will be called to finalize
3025 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3026 indicate that remote end did not send its public key (or
3027 certificate), even though we require it. Added check for this
3028 condition in the SKE. This was a security bug, now fixed.
3030 Defined new SilcSKEVerifyCbCompletion callback that is called
3031 when the verification process is completed.
3033 The affected files lib/silcske/silcske_status.h and
3034 lib/silcske/silcske.[ch].
3036 * Changed the verify_public_key client operation to be async
3037 as well. Defined SilcVerifyPublicKey callback that is used to
3038 indicate the success of the public key verification process.
3040 Changed the server and client to use the new async client
3043 * Changed the Irssi SILC client's internal scheduler to be called
3044 twice as many times as it used to be. As a result the client
3045 should be a bit faster now. Affected file is
3046 irssi/src/silc/core/silc-core.c.
3048 * Added support to Irssi SILC client of asynchronous public key
3049 verification and passphrase inquiry. Affected file is
3050 irssi/src/silc/core/silc-core.c.
3052 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Do not say "You have left channel %s" in client library.
3055 Moved it to the application. Affected files are
3056 lib/silcclient/command.c and silc/client_ops.c.
3058 * Fixed silc_client_get_clients. Command context was not
3059 duplicated and was freed memory in the callback. Affected
3060 file lib/silcclient/idlist.c.
3062 * Do not say "you are now talking..." on JOIN command in the
3063 client library. The appliation must handle it.
3065 * Do not say ".. changed topic to" in command reply in the
3066 client libary. The application must handle it.
3068 * Fixed TOPIC command sending in the client library.
3070 * Fixed a memory leak in silc_client_command_free in the file
3071 lib/silcclient/command.c.
3073 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Imported a modified version of Irssi client to the source tree.
3076 The Irssi will be used to create a new client called
3077 Irssi SILC. Imported to irssi/.
3079 Added silc_core_init_finish function to the Irssi. Affected
3080 file irssi/configure.in.
3082 A lot changes in the Makefile.ams around the irssi tree.
3084 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Do not rehash if the new size is same as the old size of the
3087 hash table, in the silc_hash_table_rehash*. The affected file
3088 lib/silcutil/silchashtable.c.
3090 * Replaced hash_table_del_by_context calls from the server
3091 (when channel->user_list and client->channels) to the
3092 hash_table_del as it is sufficient and faster.
3094 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Added silc_hash_table_list, silc_hash_table_get and the
3097 SilcHashTableList structure to provide an alternative way to
3098 traverse the hash table. The affected files are
3099 lib/silcutil/silchashtable.[ch].
3101 * Changed the server's idlist routines to use the hash table
3102 routines to optimize the code.
3104 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Replaced the client entry's `channel' list and channel entry's
3107 `user_list' list to hash tables for optimized lookup. Changed
3108 the code to use the hash table interface around the code.
3109 Affected file lib/silcd/idlist.[ch].
3111 * Added `auto_rehash' boolean argument to the function
3112 silc_hash_table_alloc to indicate whether the hash table should
3113 auto-rehash when it thinks is appropriate time. It will
3114 increase the hash table size if the there is twice as much
3115 entries in the table than the size of the table, and will
3116 decrease the size if there are twice as less entries than
3117 the size of the table.
3119 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3123 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3125 * silc_idcache_purge_by_context deletes the entry now by context
3126 as it is supposed to do. Affected file lib/silccore/idcache.c.
3128 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3129 client is not anymore valid (WHOWAS givens the info) and not
3130 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3132 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Removed the `data' and `data_len' arguments from the ID Cache
3135 interfaces and added `name' argument. ID Cache does not handle
3136 anymore the binary data only a names associated with given ID.
3138 * When hashing a Client ID with silc_hash_id the entire ID is
3139 not hashed anymore, instead only the hash of the Client ID is
3140 hashed. This way we can access the Client ID from the cache
3141 with Client ID but with the hash of the ID (which is a hash of
3142 the nickname) as well without any difference in performance.
3144 Added also silc_idcache_find_by_id_one_ext to do one on one
3145 searching when we have the actual ID. Added also function
3146 silc_hash_client_id_compare. The affected files are
3147 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3149 * When hashing the name associated with a ID it is always done
3150 in lowercase. This way we can access the cache without worrying
3151 about case-sensitivity, even though, for example nicknames are
3154 * Fixed a bug in server with channel message sending. It put
3155 wrong ID type as destination ID. The affected file
3156 silcd/packet_send.c.
3158 * silc_idcache_del_by_context now deletes from all hash tables
3159 by context. Affected file lib/silccore/idcache.c.
3161 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Changed the client library to use the new ID Cache interface.
3164 Changes around the source tree.
3166 * Added silc_hash_table_rehash_ext to rehash with specific
3167 hash function. Affected file lib/silcutil/silchashtable.[ch].
3169 * Added silc_hash_string_compare to compare two strings in the
3170 hash table. Affected file lib/silcutil/silcutil.[ch].
3172 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Added new function silc_idcache_del_by_context into the
3175 lib/silccore/idcache.[ch].
3177 * Changed the server's ID list routines to use the new ID Cache
3178 interface. Changes around the source tree.
3180 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Added silc_hash_table_del[_by_context]_ext functions in to the
3183 lib/silcutil/silchashtable.[ch].
3185 Removed silc_hash_table_find_all* routines and added new
3186 silc_hash_table_find_foreach to replace them.
3188 Added silc_hash_table_replace_ext function as extended
3189 replacing function. Separated the simple hash table interface
3190 from the extended hash table interface in the file
3191 lib/silcutil/silchashtable.h.
3193 * Fixed minor bugs and changed it to use some of the new
3194 hash table functions in lib/silccore/idcache.c
3196 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3198 * Added new function silc_hash_table_find_all to return all keys
3199 in the hash table by the specified key. As the hash table is
3200 collision resistant it also makes it possible to have several
3201 duplicate keys in the hash table. This function may be used to
3202 find all of the keys from the hash.
3204 Added user_context arguments to the SilcHashFunction,
3205 SilcHashCompare and SilcHashDestructor to deliver user specified
3208 Added new fuctions silc_hash_table_find[_all]_ext to do
3209 extended lookup with specified hash and compare functions and
3210 specified user contexts.
3212 Added new function silc_hash_table_add_ext to add the key
3213 with specified hash function and user context.
3215 Added new function silc_hash_table_foreach to traverse all
3216 entrys in the hash table. Added SilcHashForeach callback
3219 Added new function silc_hash_table_del_by_context to delete
3220 the entry only if the context associated with the key matches.
3222 Affected files are lib/silcutil/silchashtable.[ch].
3224 * Removed silc_hash_[server/client/channel]_id and added just
3225 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3226 silc_hash_id_compare to compare two ID's using as the hash table
3227 comparison function. Added also silc_hash_data to hash
3228 binary data and silc_hash_data_compare to compare it.
3230 * Removed silc_idlist_find_client_by_hash as it is not needed
3231 anymore. Affected file silcd/idlist.[ch].
3233 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3234 to use internally the SilcHashTable. The new ID Cache is a lot
3235 faster than the old one. Some of the ID Cache interface was also
3236 rewritten and obsolete and stupid functions were removed.
3238 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Added entry_count field to the SilcHashTable to keep the number
3241 of the entries in the table. Implemented the function
3242 silc_hash_table_rehash. Added new function
3243 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3245 Fixed a minor bug in silc_hash_table_free.
3247 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3248 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3249 into the lib/silcutil/silcutil.[ch].
3251 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Implemented a collision resistant hash table into the
3254 lib/silcutil/silchashtable[ch]. See the header and the source
3255 for the SilcHashTable API.
3257 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Merged dotconf version 1.0.2 into lib/dotconf.
3261 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Do not compile anything in lib/silcsim/* if the SIM support
3264 is not enabled. The tree should now compile without problems
3267 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3269 * Compiled the SILC under cygwin. Compiled and tested briefly
3270 without problems. More tests needed. The SIMs didn't compile
3273 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3275 * Fixed possible crash in silc_get_username in the
3276 lib/silcutil/silcutil.c.
3278 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Fixed a va_arg in silc/client_ops.c.
3282 * Oops, RC5 routines were named AES and caused some problems
3283 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3285 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Added new SilcIDIP structure into the lib/silccore/id.h and
3288 replaced the old `ip' fields from all SILC ID's to that type.
3289 This is a step towards IPv6 support.
3291 The silc_id_get_len takes now the ID as an extra argument.
3292 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3293 both IPv4 and IPv6 based ID's.
3295 The affected files are lib/silccore/id.[ch] and other files
3296 around the tree using these routines.
3298 * Removed the ID length arguments in server from various
3299 silc_server_send_notify_* routines -> they are not needed
3302 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3304 * Fixed memory leak in silc_encode_pem_file in the file
3305 lib/silcutil/silcutil.c.
3307 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Check minor version as well in the SKE. Affected files are
3310 silcd/protocol.c and lib/silcclient/protocol.c.
3312 * Added --identifier option to the server so that an identifier
3313 can be when creating the public key for the server. Affected
3314 file is silcd/silcd.c.
3316 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3317 lib/silccrypt/silcpkcs.c.
3319 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Register default ciphers and stuff when using -C option with
3322 the server. Affected file sildc/silcd.c.
3324 * Put back the servers public key filename format, it is better
3325 than the new one. For now, the client keys are saved with the
3326 new filename format. The affected file silc/client_ops.c.
3328 * Implemented the Cipher API for the rest of the ciphers that
3329 did not implement it or implemented it the wrong way.
3331 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Register default ciphers and stuff when using the -S option
3334 in the client. Affected file silc/silc.c. Same also when
3335 creating new key pair with -C option.
3337 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Fixed the silc_verify_public_key client operation function to
3340 save the public keys differently. The fingerprint is now
3341 used as filename and not the hostname. This way also the
3342 client keys are saved uniquely and not with hostnames. The
3343 affected file is silc/client_ops.c.
3345 * Trimmed the silc_hash_fingerprint function to remove extra
3346 whitespaces from the end of the fingerprint. The affected
3347 file is lib/silccrypt/silchash.c.
3351 * Added silc_cipher_register_default function to register all
3352 default ciphers. It can be used when configuration files
3353 does not exist and the application does not want any specific
3354 ciphers in any specific order.
3356 The SilcDList is now used as silc_cipher_list dynamically
3357 allocated cipher list. Removed the static list all together
3358 and now all ciphers must be allocated to the dynamic list.
3359 The silc_cipher_alloc routine was changed to check only the
3362 All silc_cipher_* routines that used to return int returns
3365 The affected files lib/silccrypt/silccrypt.[ch].
3367 * The same thing was done to silc_hash_* as for silc_cipher_*
3368 routines. Affected files lib/silccrypt/silchash.[ch].
3370 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3371 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3372 Added also silc_pkcs_[un]register[_default] functions.
3373 Removed the data_context from the PKCS API.
3375 * Added silc_hmac_register_default function to register default
3376 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3377 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3378 to unregister all hmacs at once.
3380 * Register the default ciphers, hash functions, PKCSs and HMACs
3381 if client's configuration file does not exist. The affected
3384 * The client did not load the hash functions from the SIM
3385 modules at all. Added support for this. Affected file is
3386 silc/clientconfig.c.
3388 * When decoding public key with silc_pkcs_public_key_decode, check
3389 the supported algorithm only if PKCS are registered. Affected
3390 file lib/silccrypt/silcpkcs.c. The same was done with the
3391 silc_pkcs_private_key_decode.
3393 * Fixed the SILC List routines to keep the list always in order.
3394 It used to change the list's order when traversing the list but
3395 not it preserves the order. Affected file lib/trq/silclist.h.
3397 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Added the client library to use the SilcSocketConnection's
3400 reference counter (by silc_socket_dup) to prevent the bug that
3401 the socket object may be freed underneath async operation.
3403 * The name resolv library checking fixes in the configure.in.pre.
3406 * Created new version of the protocol drafts for future
3407 development. The -03 drafts are the ones that will be changed
3408 in the trunk now and the -02 will remain as they are.
3410 * Send list of CUMODE notifys to the router when announcing
3411 the channel users to the router. Affected file silcd/server.c.
3412 If the router receiving channel founder CUMODE for a channel
3413 that already has channel founder it will send CUMODE notify
3414 to the sender to remove the channel founder rights from the
3415 announced client. Affected file silcd/packet_receive.c.
3417 * The CUMODE notify may now use Server ID as well as the entity
3418 who changes the mode. Updated protocool specs.
3420 * Updated INSTALL and README files.
3422 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * New web pages in the http://silc.pspt.fi. The pages was
3429 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Implemented the [DenyConnectin] config section in the server.
3432 Added silc_server_config_denied_conn to check whether incoming
3433 connection is denied. Affected file silcd/serverconfig.[ch].
3435 * Do not check the ports when checking the incoming configuration
3436 data if the port is 0, meaning any. Affected file is
3437 silcd/serverconfig.c.
3439 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Fixed buffer overflow in silc_string_compare in the file
3442 lib/silcutil/silcutil.c.
3444 * Fixed double free in silc_server_command_leave in the file
3447 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Fixed the version checking in the server. Affected file is
3452 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Fixed the configuration data fetching when accepting new
3455 connections in the server. Affected file silcd/server.c.
3457 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Added `sender_entry' argument to the function
3460 silc_server_packet_relay_to_channel so that we can check
3461 whether some destination actually belongs to the same route
3462 the sender belongs (ie, we must not resend the packet to the
3463 sender). Affected file silcd/packet_send.[ch].
3465 * Added `servername' field to the SilcClientEntry in the server
3466 to hold the name of the server where client is from. Affected
3467 file is silcd/idlist.h.
3469 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Moved the channel message encrypting in the router betwen
3472 router connections from silc_server_channel_message to the
3473 silc_server_packet_relay_to_channel since we want to check
3474 whether we have anybody channel before encrypting anything.
3475 Affected files silcd/packet_[receive/send].c.
3477 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Fixed the [AdminConnection] server config section to support
3480 multiple entries. Affected file silcd/serverconfig.c.
3482 * Added support into the server to check the validity of the
3483 incoming connection before executing any KE or authentication
3486 * The connection configuration is now saved to the KE and
3487 connection auth protocol contexts and not fetched anymore in
3488 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3490 * The local hosts listenning address and port is also resolved
3491 now when starting the server. We want to have the socket object
3492 to include the real address and port for the listener. Added
3493 new function silc_net_check_local_by_sock into the files
3494 lib/silcutil/silcnet.[ch].
3496 * Fixed a broadcast bug in server -> do not broadcast if we
3499 * Fixed a routing bug. Do not route broadcast packets ever.
3500 Broadcast packets must be processed always and not routed since
3501 they may be destined to some other host than yourself and thus
3502 would get routed without no good reason. Affected file is
3505 * Added function silc_server_config_is_primary_route to check
3506 whether primary router connection has been configured (a router
3507 configuration that we are initiating). If there is not, we
3508 will assume that there is only two routers in the SILC network
3509 and we will use the incoming router connection as our primary
3510 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3512 * Changed the order of the broadcasting. Broadcast _after_ the
3513 packet has been processed not before. Affected file is
3516 * Fixed a [ClientConnection] parsing bug. The port was never
3517 parsed correctly thus resulting to port 0. Affected file
3518 silcd/serverconfig.c.
3520 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3521 argument and did not set the broadcast packet flag. Affected
3522 file silcd/packet_send.c. Fixed same bug in the function
3523 silc_server_send_notify as well.
3525 * If we receive NEW_ID packet for our own ID in the server, ignore
3528 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3532 * Removed the nickname from the Private Message Payload.
3533 Updated the code and the protocol specs.
3535 * Updated protocol specs for submitting to the IETF.
3537 * Tweaked the Random Number Generator a bit. Affected file
3538 lib/silccrypt/silcrng.c. Exported a new function
3539 silc_rng_[global]_add_noise which can be used to add more
3542 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Do not parse packets with different timeout when protocol
3545 is active -> may cause problem with rekey. Affected file
3548 * When server receives signoff notify it must not create
3549 new channel key if the client is on any channels since the
3550 sender of the signoff notify will create it.
3552 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3554 * Added printing of error messages during SKE protocol from the
3555 failure packet sent by server during SKE. Affected file
3558 * Removed the client's failure_callback handling with timeout
3559 and handle it immediately when received.
3561 * The SKE library returned wrong type in SUCCESS and FAILURE
3562 packets. They must be 32 bit MSB not 16 bit MSB.
3564 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Ok, rewrote the logic of the re-key and now it seems to work.
3567 I tested it on high traffic with frequent re-keys without
3568 problems. Added hmac_receive (and renamed hmac to hmac_send)
3569 in SilcClientConnection in lib/silcclient/client.h and
3570 in SilcIDListData in silcd/idlist.h. Also, removed the
3571 SilcPacketParserContext's cipher and hmac fields as they are
3572 not needed anymore and actually caused some problems when
3573 the ciphers and hmac's changed underneath the packet parser.
3575 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * If re-key protocol is active then process the incoming packets
3578 synchronously since we must assure that icoming packets encrypted
3579 with the old key is processed before the new keys is set to
3580 use. This is true other packets than for REKEY packets.
3581 Affected file silcd/server.c. The same was done to client library
3582 as well, affected file lib/silcclient/client.c.
3584 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3586 * Fixed bug in client and server to accept the force send if
3587 the packet is send from silc_[server/client]_packet_process
3588 function. Otherwise the packets are never delivered, oops.
3590 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Disable force sending of packets when REKEY protocol is active.
3593 We must assure that no packet is sent directly when rekey is
3594 performed. All packets must be sent through packet queue.
3595 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3596 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3597 function is silc_[server/client]_packet_send_real to check
3600 * Replaced the SIM paths from example config files to
3601 /usr/local/modules. Also, make install creates now
3602 /usr/local/silc/logs directory to hold all the SILC server
3605 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Made the configure.in.pre work on Solaris. Patch by salo.
3609 * Made all ciphers compatible with non-x86 machines. Defined
3610 CBC mode macros into lib/silccrypt/ciphers_def.h.
3612 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Fixed the make install.
3616 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * When MAC computation fails the silc_packet_decrypt returned 0
3619 even though it was supposed to return -1. Fixed this. The
3620 affected file is lib/silccore/silcpacket.c.
3622 * Do not replace the config files in /etc/silc (in make install)
3623 if they already exist. Affected file ./Makefile.am.
3625 * Do not send re-key packets immediately but through packet queue.
3626 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3628 * Changed silc_net_check_host_by_sock to return FALSE if the
3629 IP/DNS could not be resolved. Though, it returns the IP address
3630 now even if it could not resolve it (but returns also FALSE).
3631 Affected file lib/silcutil/silcnet.[ch].
3633 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Added silc_pkcs_decode_identifier to decode the public key's
3636 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3637 Added also silc_pkcs_free_identifier. Added also new context
3638 SilcPublicKeyIdentifier.
3640 * Added -S option to the silc client. It is used to dump the
3641 contents of the specified public key file.
3643 * Changed the PKCS api to return the public key length when
3644 setting the public key.
3646 * Fixed a fatal bug in the public and private key file loading.
3647 Affected file lib/silccrypt/silcpkcs.c.
3649 * Execute the packet parsing for client with zero (0) timeout
3650 if the protocol is active. Affected file silcd/server.c.
3652 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Made the key generation options to the silcd program. Added
3655 -C option, equivalent to client's option.
3657 * Added new [ServerKeys] config section to the server. It
3658 configures the server's public and private key.
3660 * Defined generic Public Key Payload into the protocol
3661 specification to send specific type of public keys and
3664 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3665 public key or certificate.
3667 * Implemented the GETKEY command to the server and to the
3668 client library and on user interface.
3670 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Made preliminary `make install' work.
3674 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added SilcServerRekey context into silcd/idlist.h.
3678 * Added the PFS support as defined in the specification to the
3679 SKE protocol. Affected files lib/silcske/*.c.
3681 * Added `ske_group' field to the SilcServerRekey context to hold
3682 the number of the SKE group that is used with PFS in re-key.
3683 Affected file silcd/idlist.h.
3685 * Added PFS re-key support to the server. Affected file is
3688 * Added silc_protocol_cancel to cancel execution of the next
3689 state of the protocol. Affected file is
3690 lib/silccore/silcprotocol.[ch].
3692 * Added the re-key support with and without PFS to the client
3693 library. Re-key is performed once in an hour, by default.
3695 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3696 Added silc_client_rekey_callback and silc_client_rekey_final.
3697 Affected files are lib/silcclient/protocol.[ch] and
3698 lib/silcclient/client.[ch].
3700 * Removed the `hmac_key' and `hmac_key_len' fields from the
3701 SilcClientConnection structure; not needed. Affected file is
3702 lib/silcclient/client.h.
3706 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Do not ask whether user wants to use the negotiated private key
3709 for private messages, just use it. Affected file is
3710 silc/local_command.c.
3712 * Added `send_enc_key' and `enc_key_len' fields to the
3713 SilcIDListData structure since they are needed in the re-key
3714 phase. Affected file is silcd/idlist.[ch].
3716 * Implemented the simple re-key protocol into the server.
3717 Affected files silcd/server.c and silcd/protocol.[ch]. The
3718 re-key will be performed once in an hour, by default.
3720 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3721 Added silc_server_rekey, silc_server_rekey_callback and
3722 silc_server_rekey_final.

3725 and the specifications.
3727 * Adde `pfs' field to the SilcIDListData to indicate whether
3728 the PFS is to be performed in the re-key. Affected file is
3731 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3734 int64 of at least the xintXX size. If void * is less that 4
3735 bytes uint32 * will be used. Defined bool as boolean.
3737 * Changed _ALL_ unsigned long and unsigned int to uint32,
3738 unsgined short to uint16 in the source tree.
3740 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3741 not handle clients that has entry->data.registered == FALSE.
3742 They are not in the network anymore. Affected file is
3745 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3747 * Implemented the sending of the SERVER_SIGNOFF notify in the
3748 server. Affected file is silcd/server.c.
3750 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3751 Added also silc_notify_payload_encode_args into the
3752 lib/silccore/silcnotify.[ch].
3754 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3755 Affected file silcd/packet_receive.c.
3757 * Implemented the SERVER_SIGNOFF notify handling in the client
3758 library. Affected file lib/silcclient/client_notify.c. Also,
3759 implemnted the printing of the SERVER_SIGNOFF info to the
3760 application. Affected file silc/client_ops.c.
3762 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3763 if the deleting was successful. Affected file silcd/idlist.[ch].
3765 * Added support for public key authentication in the connection
3766 authentication protocol in the client library. Affected file
3767 lib/silcclient/protocol.c.
3769 * Changed the server's silc_idlist_get_clients_by_* interface
3770 to support already allocated array so that new entries may be
3771 added to pre-allocated array. Affected file silcd/idlist.[ch].
3772 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3773 and command replies.
3775 * All command reply functions in the server now calls the
3776 pending command callback even if error occured. This way the
3777 error will be delivered to the client as well. Affected files
3778 silcd/command.c and silcd/command_reply.c.
3780 * Fixed INFO command to return local server's info if no server
3781 was provided. Affected file lib/silcclient/command.c.
3783 * Removed RESTART command for good. Updated the code and the
3786 * Rewrote parts of the task system. It is a bit simpler now.
3787 Removed unsued task priorities. The affected files are
3788 lib/silcutil/silctask.[ch].
3790 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Moved the USERS printing from the library to the application.
3793 Affected files lib/silcclient/command.c and silc/client_ops.c.
3795 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Added channel key re-key support. The re-key is perfomed
3800 only by the router and is done once in an hour. Added `rekey'
3801 field to the SilcChannelEntry in the server. Affected files
3802 silcd/server.c and silcd/idlist.h.
3804 * Added silc_task_unregister_by_context into the file
3805 lib/silcutil/silctask.[ch].
3807 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Added SILC_UMODE_GONE mode to indicate when the client is not
3810 present in the SILC network. Added also support to the local
3811 command AWAY that will set this mode. Added support of showing
3812 "xxx is gone" in WHOIS command. The USERS command shows the
3813 gone status as well.
3815 * Fixed setting server and router operator privileges in the
3816 server's UMODE command. Affected file silcd/command.c.
3818 * Merged the SKE KE1 and KE2 payloads into one payload. The
3819 new KE payload is equivalent to the old KE2 payload.
3821 Cleaned up the SKE Start Payload parsing. It now uses the
3822 simple buffer unformatting to do the parsing. A lot faster
3825 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3826 to the SKE that is used to indicate whether both of the SKE
3827 parties should perform authentication. By default only the
3828 responder performs authentication. By setting this flag also
3829 the initiator must do authentication. By default it is unset
3830 since in normal SKE case, client to server connection, only
3831 the responder should do authentication. When doing SKE between
3832 two clients both should perform authentication. Updated the
3833 code and the protocol specs.
3835 * A little fix to IDENTIFY command in the server. Search the
3836 client first by hash not nickname. Affected file is
3839 * Fixed the silc_client_close_connection to support closing
3840 the client to client connections wihtout deleting too much
3841 data. Affected file lib/silcclient/client.c.
3843 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3844 are received if protocol used to be active but is not anymore
3845 the application would crash due to NULL pointer dereference.
3846 Affected files silcd/server.c and lib/silcclient/client.c.
3848 * Added `hash' field to the SilcClientConnection to include
3849 the hash function negotiated in the SKE protocol.
3851 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3852 to set the channel founder authentication data. A client can
3853 claim the founder rights later by providing the authentication
3854 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3855 This way the channel founder can regain the channel founder
3856 privileges even it is left the channel. This works only on
3857 local server and the client must be connected to the same
3858 server to be able to regain the founder rights. Updated the
3859 protocol specs accordingly.
3861 Added support to the CMODE command in the client to set the
3862 founder auth data. Read the README to see how to set it.
3864 Added support to the CUMODE command to claim the founder
3865 rights. Read the README to see how to do it.
3867 Added support for the founder authentication to the Channel
3868 Entry in the server. Affected file silcd/idlist.h.
3870 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3871 server's CMODE command. Affected file silcd/command.c.
3873 * Added the following new functions into lib/silccore/silcauth.[ch]:
3874 silc_auth_get_method and silc_auth_get_data.
3876 * The server now saves the remote hosts public key to the
3877 SilcIDListData pointer. Affected file silcd/protocol.c.
3879 * The normal server now does not remove the channel entry from
3880 the cache if the founder authentication data is set. It used
3881 to remove it if the founder was the last one on the channel on
3882 the server and left the channel. The auth data is saved and
3883 if the channel is re-joined later the old entry is used with
3884 the old auth data. Affected files silcd/command_reply.c and
3887 * Removed the `pkcs' field from the SilcIDListData structure
3888 in the server; it is not used. Affected file silcd/idlist.h.
3890 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Fixed packet processing on slow links. Partial packets were
3893 never re-processed because the incoming data buffer was cleared
3894 by the application. Application must not directly clear the
3895 sock->inbuf, the packet processing routines handle it. Fixed
3896 this in client library and in server.
3898 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Fixed the WHOIS and IDENTIFY send reply function to really
3901 check whether to send list or just one entry. Affected file
3904 * Cleaned up the LEAVE command's channel key distribution. The
3905 affected file silcd/command.c.
3907 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3908 can enforce the channel mode as well. In that case the ID
3909 includes the ID of the server. The code now enforces the
3910 mode change if the router have different mode than the server.
3912 * The notify client operation with CMODE_CHANGE notify can now
3913 return NULL client_entry pointer if the CMODE was not changed
3914 by client. Application must check for this.
3916 * Added <Server ID> argument to INFO command to support server
3917 info fetching by Server ID.
3919 * Added silc_server_announce_get_channel_users to get assembled
3920 packets of channel users of the specified channel. Affected
3921 file silcd/server.[ch].
3923 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3924 was freed underneath the ID Cache.
3926 * Re-announce clients when the server received CHANNEL_CHANGE
3927 notify from the router. Affected file silcd/packet_send.c.
3929 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3932 crashed since it did not handle the fact that there is no cipher
3933 called "3" and didn't check the error condition. Now fixed.
3935 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3936 flag. It can be used to send message requests.
3938 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Implemented the RESTART command in the client.
3942 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3943 notice type messages. Added notice printing to the user
3946 * The channel keys are not re-generated if the channel's mode
3947 is PRIVKEY, ie private key on the channel exists. Affected
3948 files silcd/server.c and silcd/command.c.
3950 * Fixed a little bug in channel message delivery when channel
3951 private keys are set in the server. Affected file is
3952 silcd/packet_send.c.
3954 * Changed the setting on channel->on_channel = TRUE from the
3955 silc_client_save_channel_key to the JOIN command reply. The
3956 key payload is not received if the private channel key is set.
3957 Affected file lib/silcclient/command_reply.c and the
3958 lib/silcclient/client_channel.c.
3960 * When the CMODE_CHANGE notify is sent and the channel private
3961 key mode is removed the channel key must be re-generated in
3962 other cells as well. Added this support for the router in the
3963 silcd/packet_receive.c.
3965 * Added new local command NOTICE to send notice message on
3966 channel. Affected file silc/local_command.[ch].
3968 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added new local command ME to the client. It is used to send
3971 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3972 some action. Affected file silc/local_command.[ch].
3974 * Changed channel_message and private_message client operations
3975 to deliver the message flags to the application. Added also
3976 the `flags' arguments to the silc_client_send_channel_message
3977 and silc_client_send_private_message functions. Affected file
3980 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Redefined the Private Message Payload to support private message
3983 keys and to support the new private message flags. Updated
3984 the protocol specs. Flags makes it possible to have for example
3985 CTCP style messages.
3987 * Added new type SilcPrivateMessagePayload and defined an API
3988 for it in the lib/silcclient/silcprivate.[ch].
3990 * Tested private message private keys successfully. Tested the
3991 private message key set, unset and list commands with the new
3994 * Redefined the Channel Message Payload to include the channel
3995 message flags (equal with private message flags) to support
3996 for example CTCP style messages.
3998 * Defined some of the message (for channel and private message)
3999 flags. Updated the protocol specs and added the flags to the
4000 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4002 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4004 * Added SilcKeyAgreementStatus type to the key agreement routines
4005 to indicate the current status and error if one occured.
4006 The status types are defined in the lib/silcclient/silcapi.h.
4008 * Added new local command KEY that is used to set and unset private
4009 keys for channels, set and unset private keys for private messages
4010 with remote clients and to send key agreement requests and
4011 negotiate the key agreement protocol with remote client. The
4012 key agreement is supported only to negotiate private message keys,
4013 it currently cannot be used to negotiate private keys for channels,
4014 as it is not convenient for that purpose.
4016 * Fixed a minor pending callback setting bug in the function
4017 silc_client_get_client_by_id_resolve, now the function works.
4018 Affected file lib/silcclient/idlist.c.
4020 * Added function silc_net_get_local_port to get local bound
4021 port by socket. Added to lib/silcutil/silcnet.[ch].
4023 * Added `sockets' and `sockets_count' fields to the SilcClient
4024 object. They hold the sockets of the listenning sockets in
4025 the client. Listenning sockets may be for example the key
4026 agreement server. Affected file lib/silcclient/client.[ch].
4027 Added functions the silc_client_add_socket and the
4028 silc_client_del_socket. They are exported to the application
4031 * Added ~./silc/clientkeys to support other client's public keys.
4033 * Renamed verify_server_key client operation to verify_public_key
4034 and added one argument to indicate the type of the connection
4035 (server, client etc.).
4037 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Added silc_server_connection_auth_request to handle the
4040 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4041 silcd/packet_receive.[ch].
4043 * Added silc_server_send_connection_auth_request into the
4044 silcd/packet_send.c to send the connection auth request packet.
4046 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4049 * Fixed the public key authentication in responder side in the
4050 server. The `auth_data' pointer includes the SilcPublicKey
4051 not the path to the public key. Affected file silcd/protocol.c.
4053 * Implemented the public key authentication in the initiator side
4054 in the server. Affected file silcd/protocol.c.
4056 * Removed the [RedirectClient] config section from the server
4057 configuration. Is not needed and I don't want to implement it.
4059 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Cleaned up the CMODE command in the server. It now works
4062 correctly and supports all the modes defined in the protocol.
4063 Affected file is silcd/command.c.
4065 * Added `hmac_name' field to the SilcChannelEntry in the server
4066 to hold the default HMAC of the channel. It can be set when
4067 creating the channel (with JOIN command). Affected files
4070 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4071 type to indicate the change of the current cipher and hmac
4072 on the channel. Client can safely ignore the <cipher> argument
4073 (if it chooses to do so) since the CHANNEL_KEY packet will
4074 force the channel key change anyway. The <hmac> argument is
4075 important since the client is responsible of setting the new
4076 HMAC and the hmac key into use.
4078 * Fixed the CMODE command in the client library as well.
4080 * Tested CMODE command in router environment successfully.
4082 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Show the version of the remote client (or server) when connecting
4085 to the server. It is logged to the log file. Affected file
4086 is silcd/protocol.c.
4088 * Fixed the KILLED notify handling in the client library. The
4089 client must be removed from all channels when receiving the
4092 Also, do not remove the client entry when giving the KILL
4093 command but when the KILLED notify is received.
4095 * Removed silc_idlist_find_client_by_nickname from the server.
4096 Not needed anymore. Affected files silcd/idlist.[ch].
4098 * Implemented the CHANNEL_CHANGE notify type handling to the
4099 server. Affected file silcd/server.c.
4103 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Added silc_server_send_notify_invite to send the INVITE
4106 notify between routers.
4108 * Implemented the INVITE command correctly to the server.
4110 * Implemented the INVITE notify type handling in the server.
4112 * Implemented the INVITE command to the client library and on the
4115 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Added function silc_server_get_client_resolve to find the
4118 client entry by ID from all ID lists and then resolve it
4119 (using WHOIS) if it cannot be found. Affected file is
4122 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Implemented the BAN command to the client library.
4126 * The JOIN command in the server now checks the invite list
4129 * Changed the silc_command_reply_payload_encode_va and the
4130 silc_command_payload_encode_va to support that if argument is
4131 NULL it ignores and checks the next argument. Affected file
4132 lib/silccore/silccommand.c.
4134 * Added silc_server_send_notify_ban to send the BAN notify
4135 type between routers.
4137 * Chaned the silc_notify_payload_encode to support that if
4138 argument is NULL it ignores and checks the next argument.
4139 Affected file lib/silccore/silcnotify.c.
4141 * Tested ban lists in router environment successfully.
4143 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4145 * Implemented BAN command to the server, in silcd/command.[ch].
4147 * Removed the BAN and INVITE_LIST modes from the CMODE command
4150 * Added function silc_string_match to regex match two strings.
4151 Affected files lib/silcutil/silcutil.[ch].
4153 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Redefined parts of the SilcChannelEntry in the server to support
4156 the new ban and invite lists.
4158 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Redefined the INVITE command. The same command can be used to
4161 invite individuals to the channel but also to manage the invite
4162 list of the channel (to add to and remove from the invite list).
4163 Updated the protocol specs.
4165 * Added new command SILC_COMMAND_BAN that can be used to manage
4166 the ban list of the channel. Updated the protocol specs.
4168 * Removed the channel modes: the SILC_CMODE_BAN and the
4169 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4170 in the CMODE command. The equivalent features are now available
4171 using INVITE and BAN commands. Updated the protocol specs.
4173 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4174 in the network about change in the current ban list. The notify
4175 type is not used by the client.
4177 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4178 support the invite lists.
4180 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4182 * Added new function silc_string_regexify that converts string
4183 including wildcard characters into regex string that can
4184 be used by the GNU regex library. Added into the file
4185 lib/silcutil/silcutil.[ch].
4187 Added silc_string_regex_combine to combine to regex strings
4188 into one so that they can be used as one regex string by
4189 the GNU regex library. Added into the file
4190 lib/silcutil/silcutil.[ch].
4192 Added silc_string_regex_match to match two strings. It returns
4193 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4195 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Imported GNU regex to the soruce tree into lib/contrib.
4198 Fixed some compiler warning from the regex.c.
4200 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Fixed MOTD command in the server to work in router environment.
4204 * Fixed the MOTD command in the client library to support
4205 the server argument in the command.
4207 * Added `nickname_len' argument to the silc_idlist_add_client
4208 in the server, as the `nickname' argument may be binary data
4211 * Added silc_idlist_get_channels to return all channels from
4214 * Implemented LIST command to the server. Affected file is
4217 * Implemented the LIST command to the client library and on the
4220 * Added [<user count>] argument to the LIST command reply.
4221 With private channels the user count is not shown.
4223 * Updated TODO and README.
4225 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * The client entry's data.registered must be TRUE even with
4228 global client entry on global client list. The data.registered
4229 is used to check whether the client is anymore in the network,
4230 for example with WHOWAS command so it must be valid.
4232 * Fixed the WHOWAS command in the server. It now actually works
4233 in router environment. Added function into silcd/command_reply.c
4234 silc_server_command_reply_whowas_save.
4236 * Added silc_idlist_purge function to the silcd/idlist.c
4237 to periodically purge the ID Cache.
4239 * Fixed INFO command in the server. It works now in router
4240 environment. Added <server name> argument to the INFO command
4241 reply. Updated the protocol specs.
4243 * Fixed minor bug in silc_idcache_purge to not purge if the
4244 expire value is zero.
4246 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4247 they were buggy because of the WHOWAS information.
4249 * Fixed local command MSG to handle the async resolving of
4250 the remote client properly. It used to fail the first MSG.
4251 Affected file silc/local_command.c.
4253 * Added `data_len' field to SilcIDCache context.
4255 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Update TODO. Todo in commands in the server.
4259 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4262 used by routers as broadcast packet to inform other routers
4263 about the changed user mode.
4265 Implemented the notify handling in the server. Affected file is
4266 silcd/packet_receive.c. Added the function
4267 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4269 * Added new generic Channel Payload and deprecated the New Channel
4270 Payload. The New Channel Payload is now the generic Channel
4273 * Added new argument `mode' to the silc_server_send_new_channel
4274 as it is required in the Channel Payload now.
4276 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4277 and created a new and real SilChannelPayload to represent the
4278 new generic Channel Payload. Implemented the encode/decode
4279 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4281 * Added silc_server_get_client_channel_list to return the list
4282 of channels the client has joined for WHOIS command reply.
4283 Affected file silcd/server.[ch].
4285 * Implemented the channel list sending in the WHOIS command reply
4286 in server and in the client.
4288 Implemented the channel list displaying on the user interface
4289 as well. Affected file silc/client_ops.c.
4291 * Added silc_channel_payload_parse_list to parse list of Channel
4292 Payloads. It returns SilcDList list of SilcChannelPayloads.
4293 Client for example can use this function to parse the list of
4294 channels it receives in the WHOIS command reply. The caller
4295 must free the list by calling silc_channel_payload_list_free.
4296 Affected files lib/silccore/silcchannel.[ch].
4298 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Added one new argument <user mode> to the WHOIS command reply
4301 to return the mode of the user in SILC. Updated the protocol
4304 Implemented it to the server and client.
4306 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Fixed the mode printing on the user interface on joining.
4309 Affected file silc/client_ops.c.
4311 * Implemented the UMODE command and user modes in general to the
4312 client library and to the user interface.
4314 * Implemented the UMODE command to the server.
4316 * The server now sends UNKNOWN_COMMAND error status if client sends
4317 unknown command. Affected file silcd/command.c.
4319 * All server commands now handle the command identifier the right
4320 way when sending the command reply to the client. The client can
4321 use to identify the command replies with the identifier.
4323 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Added silc_server_get_client_route to resolve the route to
4326 the client indicated by the client ID. Affected file is
4329 * Added silc_server_relay_packet as general function to relay
4330 packet to arbitrary destination. This deprecates functions
4331 like _send_private_message_key, _relay_notify etc. Affected
4332 file is silcd/packet_send.[ch].
4334 Removed silc_server_send_key_agreement,
4335 silc_server_send_private_message_key and
4336 silc_server_packet_relay_notify functions from the file
4337 silcd/packet_send.[ch].
4341 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4342 server. Affected file silcd/packet_receive.[ch].
4344 * Implemented the KILL command to the client. Implemented the
4345 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4346 Affected files lib/silcclient/command[_reply].c and
4347 lib/silcclient/client_notify.c. Implemented the KILL notify
4348 printing in the user inteface.
4350 * Fixed a lot silc_parse_nick memory leaks from the client
4351 library in the file lib/silcclient/command.c.
4353 * Changed the silc_server_send_notify_on_channels's `sender'
4354 argument from SilcSocketConnection to SilcClientEntry to
4355 check the sender as entry and not as connection object and not
4356 to send to the client provided as argument. The affected file
4357 is silcd/packet_send.[ch].
4359 * The notify packets that are destined directly to the client used
4360 to not to be processed by the server. Now changed that and the
4361 server processes all notify packets. After relaying the packet
4362 to the client the notify packet is processed in the server.
4364 * The silc_server_free_client_data now checks whether there is
4365 pending outgoing traffic for the client and purges the data to
4366 the network before removing the client entry.
4368 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4371 an client is killed from the SILC Network. Updated the protocol
4374 Added new function silc_server_send_notify_killed to the
4375 silcd/packet_send.[ch].
4377 * Added function silc_server_packet_relay_notify to relay notify
4378 packets that are destined directly to a client. In this case
4379 the server does not process the notify packets but merely relays
4380 it to the client. Affected file silcd/packet_send.[ch].
4382 Added also silc_server_packet_process_relay_notify to check
4383 whereto relay the notify. Affected file is
4384 silcd/packet_receive.[ch].
4386 * Implemented the KILL command to the server.
4390 * Added the backup schema desgined last fall to the protocol
4391 specs for everyone to see. The specification is in the
4392 *-spec-xx.txt draft and the packet type definitions for the
4393 backup routers is in *-pp-xx.txt draft. Thusly, added also
4394 new packet type SILC_PACKET_CELL_ROUTERS.
4396 * A big security problem in the implementation discovered. The
4397 signoff of an client did not cause new channel key generation
4398 which it of course should've done. The channel keys must be
4399 always re-generated when client leaves (or signoffs) the channel.
4400 The silc_server_remove_from_channels funtion now handles
4401 the channel key re-generation.
4403 * Added `sender' argument to the silc_server_send_notify_on_channels
4404 to not to send the client provided as argument. Affected file
4405 silcd/packet_send.[ch].
4407 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Implemented OPER and SILCOPER commands into the server and
4412 * Added silc_auth_verify and silc_auth_verify_data to verify
4413 the authentication directly from the authentication payload.
4414 It supports verifying both passphrase and public key based
4415 authentication. Affected file lib/silccore/silcauth.[ch].
4417 * Added `hash' field to the SilcIDListData structure. It is the
4418 hash negotiated in the SKE protocol. Affected file is
4421 * Slight redesigning of the SilcAuthPayload handling routines.
4422 Do not send SilcPKCS but SilcPublicKey as argument.
4424 * Implemented the public key authentication support to the
4425 serverconfig. The public key is loaded from the provided path
4426 and saved as authentication data to void * pointer. Thus,
4427 changed the unsigned char *auth_data to void *auth_data;
4429 * Fixed SHUTDOWN command to send the reply before the server
4430 is shutdown. :) Affected file silcd/command.c.
4432 * Fixed fatal bug in CONNECT command. The hostname was invalid
4433 memory and server crashed. Affected file silcd/command.c.
4435 * Fixed fatal bug in CLOSE command. The server_entry became
4436 invalid but was referenced later in the command. Affected file
4439 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * Fixed fatal bug in failure packet handling. Server ignored
4442 the failure and thus crashed when it came.
4446 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4449 that the command may be executed only once in (about) 2 seconds.
4450 The old SILC_CF_LAG flag is same but allows command bursts up
4451 to five before limiting.
4453 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4454 server code. Various commands now includes the CF_LAG_STRICT
4455 flag to disallow any kind of miss-use of the command.
4457 * Fixed the silc_buffer_unformat to not to allocate any data
4458 if the length of the data is zero. It used to allocate the
4459 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4461 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Changed the format of AdminConnection configuration section
4464 in the server. Added username of the admin to the format.
4465 Affected files silcd/serverconfig.[ch].
4467 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4468 to return admin configuration data by host, username and/or
4471 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Implemented WHOWAS command to the server. Added the functions:
4475 silc_server_command_whowas_parse,
4476 silc_server_command_whowas_send_reply,
4477 silc_server_command_whowas_from_client and
4478 silc_server_command_whowas_from_server
4480 * Added <Client ID> argument to the WHOWAS command reply. Updated
4481 the protocol specs accordingly.
4483 * Implemented WHOWAS command and command_reply to the client
4486 Implemented the WHOWAS printing on the user interface.
4488 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Added new argument to the WHOWAS command reply, the real name.
4491 It is an optional argument. Updated the protocol specs.
4493 * Added SilcIDCacheDestructor callback that is registered when
4494 the SilcIDCache is allocated. The callback is called when
4495 an cache entry in the ID Cache expires, or is purged from the
4496 cache. Added into lib/silccore/idcache.[ch].
4498 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4499 to destruct the client entries when the cache entry expires.
4500 Other ID Cache's in server and in the client library ignores
4503 * If the ID Cache entry's `expire' field is zero then the entry
4504 never expires. Added boolean `expire' argument to the
4505 silc_idcache_add function in the lib/silccore/idcache.[ch].
4506 If it is TRUE the default expiry value is used.
4508 * Added silc_server_free_client_data_timeout that is registered
4509 when client disconnects. By default for 5 minutes we preserve
4510 the client entry for history - for WHOWAS command.
4512 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Added support to the server to enforce that commands are not
4515 executed more than once in 2 seconds. If server receives
4516 commands from client more frequently, timeout is registered
4517 to process the commands. Affected file silcd/command.c.
4518 Added new function silc_server_command_process_timeout.
4520 * Changed NICK_NOTIFY handling in client library to check that
4521 if the client's nickname was changed, so there is no need to
4522 resolve anything from the server.
4524 * Removed error printing from the WHOIS and IDENTIFY commands.
4525 If error occurs then it is ignored silently in the client library.
4526 The application, however, may map the received error to
4527 human readable error string. The application currently maps
4528 the NO_SUCH_NICKNAME error to string.
4530 * Made the command status message public to the application. Moved
4531 them from lib/silcclient/command_reply.c to
4532 lib/silcclient/command_reply.h. The application can map the
4533 received command status to the string with the
4534 silc_client_command_status_message function.
4536 * Added check to the server to check that client's ID is same
4537 as the Source ID in the packet the client sent. They must
4540 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Added dist-bzip hook to the Makefile.am to make bzip2
4543 compressed distributions.
4545 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Server now enforces the maximum length for the nickname and
4548 the channel as protocol specification dictates. 128 bytes for
4549 nickname and 256 bytes for channel name.
4551 * Moved the WHOIS printing to the application. The client libary
4552 does not print out the WHOIS information anymore, the application
4553 must do it. Renamed silc_client_command_reply_whois_print to
4554 the silc_client_command_reply_whois_save.
4556 The client's idle time is also sent to the application now, and
4557 the idle is shown on screen.
4559 * Added silc_client_command_reply_identify_save to save the
4560 received IDENTIFY entries.
4562 * Do not check for channel private keys in message sending and
4563 reception if the channel does not have the PRIVKEY mode set.
4564 Affected file lib/silclient/client_channel.c.
4566 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4569 just surfaced after chaning the JOIN procedure.
4571 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Added silc_client_get_clients_by_list to get client entries
4574 from Client ID list, that is returned for example by JOIN
4575 and USERS command replies. The application should use this
4576 function for example when JOIN command reply is received to
4577 resolve the clients already on the channel (library does not
4578 do that anymore as USERS command reply is not used in the JOIN
4579 procedure anymore). Affected files lib/silcclient/silcapi.h and
4580 lib/silcclient/idlist.c.
4582 * JOIN command reply and USERS command reply returns now SilcBuffer
4583 pointers instead of unsigned char pointers when returning
4584 the client list and mode list.
4586 * Added <Client ID> argument to the JOIN command reply, mainly
4587 for the server to identify for which client the command was
4588 originally sent. Updated protocol specs accordingly.
4590 * Added SilcDlist private_key pointer to the SilcChannelEntry
4591 in the client to support the channel private keys. Affected
4592 file is lib/silcclient/idlist.h.
4594 * Added SilcChannelPrivateKey argument to the function
4595 silc_client_send_channel_message so that application can choose
4596 to use specific private ke if it wants to. If it is not provided,
4597 the normal channel key is used, unless private keys are set.
4598 In this case the first (key that was added first) is used
4599 as the encryption key.
4601 * Implemented the support for channel private key handling.
4602 Implemented the following functions:
4604 silc_client_add_channel_private_key,
4605 silc_client_del_channel_private_keys,
4606 silc_client_del_channel_private_key,
4607 silc_client_list_channel_private_keys and
4608 silc_client_free_channel_private_keys
4610 Affected file lib/silcclient/client_channel.c.
4612 * Added the support for the private keys in the channel message
4613 sending and encryption and in the message reception and
4614 decryption. Affected funtions are
4615 silc_client_send_channel_message and silc_client_channel_message.
4617 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Added SKE's key verify callback to the client library's
4620 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4622 * Removed the statement that server (or router) must send USERS
4623 command reply when joining to the channel so that the client
4624 knows who are on the channel. Instead, the client list and
4625 client's mode list is now sent in the JOIN command reply to the
4626 client who joined channel. This is better solution.
4628 * Added function silc_server_get_users_on_channel and function
4629 silc_server_save_users_on_channel to the silcd/server.[ch].
4631 * Removed function silc_server_command_send_users from the
4634 * Do not show topic on the client library anymore. The topic is
4635 sent in the command reply notify to the application and the
4636 application must show the topic now.
4638 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * Added client searching by nickname hash into the IDENTIFY and
4641 WHOIS commands in the server as they were clearly missing from
4642 them. Affected file is silcd/command.c.
4644 * Fixed a bug in private message receiving in the client library.
4645 The remote ID was freed and it wasn't supposed, now it is
4648 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Minor fix to the channel payload; allocate the data area, as it
4651 needs to be of specific length.
4653 * If the key agreement port is zero then the operating
4654 system will define the bound port. Affected files are
4655 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4657 * Added new function silc_channel_payload_decrypt into the file
4658 lib/silccore/silcchannel.[ch].
4660 * Moved the channel message etc, check from silc_packet_decrypt
4661 to applications. The library calls now a generic
4662 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4663 when the packet is either normal or special. This was done to
4664 allow more wide range of checking that was not allowed when
4665 the code was in library. Now applications can do virtually any
4666 checks to the packet and return to the library the decision how
4667 the packet should be processed. Affected files are
4668 lib/silccore/silcpacket.[ch].
4670 Added silc_server_packet_decrypt_check to the server and
4671 silc_client_packet_decrypt_check to the client library.
4673 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4674 to send with specified source and destination information.
4676 * Channel message delivery between routers was broken after the
4677 channel key distribution was fixed earlier. The channel key
4678 was used be to distributed to other routers as well which is not
4679 allowed by the protocol. Now this is fixed and channel keys
4680 really are cell specific and the channel message delivery between
4681 routers comply with the protocol specification.
4683 * Fixed various commands in server to check also the global list
4684 for the channel entry and not just the local list. The affected
4685 file silcd/command.c.
4687 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Added assert()s to buffer formatting and unformatting routines
4690 to assert (if --enable-debug) when error occurs. Affected
4691 file: lib/silcutil/silcbuffmt.c.
4693 * Changed to auto-reconnect to check whether the remote host is
4694 router and register the re-connect timeout if it is. It used
4695 to check that whether we are normal server, but router must do
4696 auto-reconnect with another router as well. Affected file
4699 * Removed the [<key len>] option from CMODE command as the cipher
4700 name decides the key length, nowadays. See the defined ciphers
4701 from the protocol specification.
4703 * Added [<hmac>] option to the CMODE command to define the HMAC
4704 for the channel. Added SILC_CMODE_HMAC channel mode.
4706 * Added [<hmac>] option for the JOIN command so that user can
4707 select which HMAC is used to compute the MACs of the channel
4710 * Added Hmac field to the Channel Message Payload. The integrity
4711 of plaintext channel messages are now protected by computing
4712 MAC of the message and attaching the MAC to the payload. The
4713 MAC is encrypted. Now, it is clear that this causes some
4714 overhead to the size of the packet but rationale for this is that
4715 now the receiver can verify whether the channel message decrypted
4716 correctly and also when private keys are set for the channel the
4717 receiver can decrypt the packet with several keys and check from
4718 the MAC which key decrypted the message correctly.
4720 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4721 lib/silccrypt/silccipher.[ch].
4723 * Added silc_hash_len to return the digest length into the
4724 lib/silcrypt/silchash.[ch].
4726 * Rewrote parts of Silc Channel Payload interface in the
4727 lib/silccore/silcchannel.[ch]. The encode function now also
4728 encrypts the packet and parse function decrypts it.
4730 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4732 * Fixed a minor formatting bug in the SKE's key material processing.
4733 It actually might have processed the keys wrong way resulting
4736 * Redefined the mandatory HMAC algorithms and added new algorithms.
4737 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4738 and hmac-md5 truncated to 96 bits. The mandatory is now
4739 hmac-sha1-96. Rest are optional (including the one that used
4740 to be mandatory). Rationale for this is that the truncated HMAC
4741 length is sufficient from security point of view and can actually
4742 make the attack against the HMAC harder. Also, the truncated
4743 HMAC causes less overhead to the packets. See the RFC2104 for
4746 * Added new [hmac] configuration section. The SKE used to use
4747 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4748 is of course wrong. The official names that must be proposed in
4749 the SKE are the ones defined in the protocol specification
4750 (hmac-sha1-96 for example). The user can configure any hmac
4751 using any hash function configured in the [hash] section. At
4752 least, the mandatory must be configured.
4754 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4756 * Added HMAC list to the SKE proposal list. It has now both
4757 hash algorithm list and HMAC list. This makes the protocol
4758 incompatible with previous versions. The SKE now seems to work
4759 the way it is supposed to work, for the first time actually.
4761 * Defined plain Hash algorithms to the protocol specification.
4764 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Implemented support for key agreement packets into the server.
4767 Added functions silc_server_key_agreement and
4768 silc_server_send_key_agreement. Other than these functions,
4769 server has nothing to do with this packet.
4771 * Added support for private message key packets into the server.
4772 Added functions silc_server_private_message_key and
4773 silc_server_send_private_message_key.
4777 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4778 called in the protocol's final callback instead in the END
4779 protocol state. This makes a little more sense and in the same
4780 time in client we can use the same protocol routines for normal
4781 key exchange and to key agreement packet handling as well.
4783 * Added to both client's and server's KE protocol context the
4784 SilcSKEKeyMaterial pointer to save the key material. We will
4785 bring the key material to the protocol's final callback by doing
4786 this. The final callback must free the key material.
4788 * Added SKE's packet_send callback into client's KE protocol
4789 context so that the caller can choose what packet sending function
4790 is used. This way we can use different packet sending when
4791 doing normal SKE when doing key agreement packet handling (in
4792 the key agreement packet handling we do not want to encrypt
4795 * Implemented the responder side of the key agreement routines
4796 in the client. The client can now bind to specified port and
4797 accept incoming key negotiation. The key material is passed
4798 to the application after the protocol is over.
4800 * Implemented the processing of incoming Key Agreement packet
4801 in the client. Added function silc_client_key_agreement to
4804 * Implemented the intiator side of the key agreement routines
4805 in the client. The client can now initiate key agreement with
4806 another remote client. The key material is passed to the
4807 application after the protocol is over.
4809 * Created client_keyagr.c to include all the key agreement
4812 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4813 SILC_TASK_CALLBACK except that it is not static.
4815 * Created client_notify.c and moved the Notify packet handling
4816 from the client.[ch] into that file.
4818 * Created client_prvmsg.c and moved all private message and
4819 private message key routines from the client.[ch] into that file.
4821 * Create client_channel.c and moved all channel message and
4822 channel private key routines from the client.[ch] into that file.
4824 * Changed silc_client_get_client_by_id_resolve to resolve with
4825 WHOIS command instead of IDENTIFY command, in the file
4826 lib/silclient/idlist.c.
4828 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Implemented the SKE's responder side to the Client library.
4832 * When FAILURE is received to the protocol do not trust it
4833 blindly. Register a timeout to wait whether the remote closes
4834 the connection as it should do it, only after that process the
4835 actual failure. This was changed to both client and server.
4837 * Added client_internal.h to include some of the structures
4838 there instead of client.h in lib/silcclient/.
4840 * Added function silc_task_unregister_by_callback to unregister
4841 timeouts by the callback function.
4843 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4845 * Some "Incomplete WHOIS info" errors has been appearing on the
4846 log files. Took away the entry->userinfo check from WHOIS
4847 reply sending. The entry->userinfo is now " " if client did not
4848 provide one. I thought this was fixed earlier but something
4849 is wrong still. Let's see if the error still appears.
4851 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4853 * Fixed a minor bug in the login when the channel key is
4854 re-generated in the server. It used to generate the key in
4855 wrong order and thus caused problems in the channel traffic.
4857 * Fixed a minor bug in channel key distsribution after
4858 KICK command. The key was not sent to the router even though
4861 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4863 * Added silc_ske_process_key_material_data as generic routine
4864 to process any key material as the SILC protocol dictates. The
4865 function is used by the actual SKE library but can be used by
4866 applications as well. This relates to the private message keys
4867 and the channel private keys since they must be processed the
4868 same way the normal SILC session keys. The protocol dictates
4869 this. Affected files: lib/silcske/silcske.[ch].
4871 Added also silc_ske_free_key_material to free the
4872 SilcSKEKeyMaterial structure.
4874 * Defined silc_cipher_set_key function to set the key for
4875 cipher without using the object's method function. The affected
4876 files: lib/silccrypt/silccipher.[ch].
4878 * Implemented silc silc_client_add_private_message_key,
4879 silc_client_add_private_message_key_ske,
4880 silc_client_del_private_message_key,
4881 silc_client_list_private_message_keys and
4882 silc_client_free_private_message_keys functions in the
4885 Added functions silc_client_send_private_message_key to send
4886 the Private Message Key payload and silc_client_private_message_key
4887 to handle incoming Private Message Key payload.
4889 * Added Cipher field to the Private Message Key payload to set
4890 the cipher to be used. If ignored, the default cipher defined
4891 in the SILC protocol (aes-256-cbc) is used.
4893 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Removed lib/silcclient/ops.h file.
4897 Redefined parts of the SILC Client Library API. Created new
4898 file silcapi.h that deprecates the ops.h file and defines the
4899 published Client Library API. Defined also private message key
4900 API and channel private key API into the file.
4902 This is the file that the application must include from the
4903 SILC Client Library. Other files need not be included by
4904 the application anymore.
4906 * Added new key_agreement client operation callback and also
4907 defined the Key Agreement library API for the application.
4909 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4912 is used by clients to request key negotiation between another
4913 client in the SILC network. If the negotiation is started it
4914 is performed using the SKE protocol. The result of the
4915 negotiation, the secret key material, can be used for example
4916 as private message key.
4918 Implemented the Key Agreement payload into the files
4919 lib/silccore/silauth.[ch].
4921 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Redefined ciphers for the SILC protocol. Added some new ciphers
4924 and defined the key lengths for the algorithms. Changed the
4925 code accordingly. The default key length is now 256 bits.
4927 * Fixed SKE key distribution function silc_ske_process_key_material
4928 when the key length is more than 128 bits. The default key
4929 length in SILC is now 256 bits.
4931 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4932 to indicate unsupported algorithm.
4934 * Renamed rijndael.c to aes.c and all functions as well.
4936 * Fixed a long standing channel key setting bug in client library.
4937 Weird that it has never surfaced before.
4939 * Fixed bug in channel deletion. If the entire channel is removed
4940 then it must also delete the references of the channel entry
4941 from the client's channel list as the client's channel entry and
4942 the channel's client entry share same memory.
4944 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Implemented CONNECT and SHUTDOWN commands in the client.
4948 * Implemented CLOSE command to the client.
4950 * Added the function silc_idlist_find_server_by_name into the
4951 files silcd/idlist.[ch].
4953 Added the function silc_idlist_find_server_by_conn into the
4954 files silcd/idlist.[ch].
4956 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * DIE command was renamed to SHUTDOWN. Updated the both code
4961 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4962 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4964 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4967 * Added function silc_server_create_connection function to create
4968 connection to remote router. My server implementation actually
4969 does not allow router to connect to normal server (it expects
4970 that normal server always initiates the connection to the router)
4971 so the CONNECT command is only good for connecting to another
4974 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4977 or some other client was kicked from the channel.
4979 Implemented the handling of the notify type to both client
4982 Implemented silc_server_send_notify_kicked to send the KICKED
4983 notify. It is used to send it to the server's primary router.
4985 * Implemented the KICK command into server and client.
4987 * Added `query' argument to the silc_idlist_get_client function
4988 to indicate whether to query the client from server or not if
4991 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4992 to indicate that the client is not channel founder.
4996 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4998 * Removed the rng context from SilcPacketContext structure and
4999 changed that the packet routine uses the Global RNG API.
5001 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Added support for quit message that client can "leave" on the
5004 channel when it quits the SILC. It is ditributed inside the
5005 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5007 Added silc_server_free_client_data that will take the
5008 signoff message as argument.
5010 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5012 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5014 * Updated parts of the protocol specification to keep it up
5017 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5020 payloads in one packet.
5022 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5023 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5024 use now the new List flag.
5026 * Also deprecated the following packet types: REPLACE_ID,
5027 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5029 * Added list support for Notify packet in server.
5031 * Added silc_server_send_notify_channel_change to send the
5032 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5033 the silc_server_send_replace_id.
5035 * Added silc_server_send_notify_nick_change to send the
5036 NICK_CHANGE notify type. Deprecates the function
5037 silc_server_send_replace_id.
5039 * Added silc_server_send_notify_join to send the JOIN notify type.
5040 Deprecates the function silc_server_send_new_channel_user.
5042 * Added silc_server_send_notify_leave to send LEAVE notify type.
5043 Deprecates the function silc_server_send_remove_channel_user.
5045 * Added silc_server_send_notify_cmode and
5046 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5047 types. Deprecates the silc_server_send_set_mode function.
5049 * Added SERVER_SIGNOFF notify type to indicate that server has
5050 quit. This means that all clients on the channel from that
5051 server will drop. This can be also used when netsplit happens.
5053 Deprecated REMOVE_ID packet type since it is not needed anymore
5056 Added silc_server_send_notify_server_signoff to send the
5057 SERVER_SIGNOFF notify type. Deprecates the function
5058 silc_server_send_remove_id.
5060 Added also silc_server_send_notify_signoff to send the
5061 SIGNOFF notify type.
5063 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5064 SILC protocol from this day on. Changed the protocol
5065 specification as well.
5067 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5068 notify type. It is used between routers to notify about
5069 topic changes on a channel.
5071 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5074 * Partly updated the protocol specification to comply with the
5075 changes now made. It is still though a bit outdated.
5077 * The JOIN notify type now takes one extra argument <Channel ID>.
5078 The packet used to be destined to the channel but now the
5079 JOIN type may be sent as list thus it is impossible to
5080 destine it to any specific channel. By adding this argument
5081 it is again possible.
5083 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Added CREDITS file. The CHANGES and CREDITS file will appear
5086 in the distribution as well.
5088 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5091 types in the server's silcd/packet_receive.c.
5093 * Implemented CMODE and CUMODE to work in router environment.
5095 * Fixed minor encoding and decoding buglet from the
5096 lib/silccore/silcmode.c.
5098 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5101 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5103 * Changed all SilcConfigServer* and silc_config_server* to
5104 SilcServerConfig* and silc_server_config*, respectively.
5107 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Associated the ID (client or server ID) to the Authentication
5110 Payload to avoid any possibility of forging. Updated the
5111 protocol specification and the code accordingly.
5113 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * The RSA key length is now save to the RsaKey context in the
5116 key generation process in lib/silccrypt/rsa.c. The key length
5117 is now used to figure out the maximum size of the block allowed
5118 to be encrypted/signed.
5120 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5121 is equivalent to the silc_mp_mp2bin but does not allocate any
5124 * Changed silc_mp_mp2bin API to take length argument. If it is
5125 non-zero then the buffer is allocated that large. If zero, then
5126 the size is approximated using silc_mp_sizeinbase, which however
5129 * Created Global RNG API which is global RNG that application can
5130 initialize. After initializing, any routine anywhere in the
5131 code (including library) can use RNG without allocating a new
5132 RNG object. This was done to allow this sort of use of the
5133 RNG in code that has no chance to allocate RNG object. All
5134 applications currently allocate this and many routines in the
5135 library use this. Affected file lib/silccrypt/silcrng.[ch].
5137 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5138 it to use the Global RNG API.
5140 * Defined Authentication Payload into protocol specification that
5141 is used during SILC session to authenticate entities. It is
5142 used for example by client to authenticate itself to the server
5143 to obtain server operator privileges.
5145 Implemented this payload into the lib/silccore/silcauth.[ch].
5146 Implemented also routines for public key based authentication
5147 as the new protocol specification dictates.
5149 Moved definitions of different authentication methods from
5150 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5152 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5153 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5154 silc_pkcs_verify_with_hash functions into the file
5155 lib/silccrypt/silcpkcs.[ch].
5157 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * The client entry's userinfo pointer must be always valid.
5160 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5161 will fail since it requires the userinfo. Now, the userinfo
5162 is allocated as "" if actual userinfo does not exist. Actually,
5163 it must exist and it is totally Ok to drop client connections
5164 that does not announce the userinfo. However, we will make
5165 this workaround for now.
5167 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5168 to return the remote port by socket.
5170 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5173 SILC_SERVER_PENDING_EXEC and added an new macro
5174 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5175 data or when error occurs while processing the pending command.
5177 Added new argument `destructor' into silc_server_command_pending
5178 and to the SilcServerCommandPending object. This destructor is
5179 now called after calling the pending callback or if error occurs
5180 immediately. If error occurs the actual pending callback won't
5181 be called at all - only the destructor. The destructor may be
5182 NULL if destructor is not needed.
5184 All this applies for client library code as well. Similar
5185 changes were made there as well for the pending commands.
5187 In the client, the application must now allocate the
5188 SilcClientCommandContext with the silc_client_command_alloc
5191 * Added reference counter to the SilcServerCommandContext. Added
5192 function silc_server_command_alloc and silc_server_command_dup
5195 Same type of functions added to the client library for the same
5198 * Removed the cmd_ident from IDListData away since it is now
5199 global for all connections. It is the command identifier used
5200 in command sending and with pending commands. The affected file
5203 * Added reference counter to the SilcSocketConnection objecet to
5204 indicate the usage count of the object. The object won't be
5205 freed untill the reference counter hits zero. Currently only
5206 server uses this, and client ignores it. The client must be
5207 set to use this too later. The affected files are
5208 lib/silccore/silcsockconn.[ch]. Added also the function
5209 silc_socket_dup to increase the reference counter.
5211 This was mainly added because it is possible that the socket
5212 is removed underneath of pending command or other async
5213 operation. Now it won't be free'd and proper DISCONNECTING
5214 flags, etc. can be set to avoid sending data to connection that
5215 is not valid anymore.
5217 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5218 the connection. After that it sets SILC_SET_DISCONNECTED.
5219 It is, however, possible that the socket data is not still freed.
5220 The silc_server_packet_process now checks that data is not
5221 read or written to connection that is DISCONNECTED. The socket
5222 get's freed when the reference counter hits zero.
5224 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Changed the client operation API: channel_message operation's
5227 `sender' is now the client entry of the sender, not the nickname
5228 and the `channel' is the channel entry, not the channel name.
5230 In the private_message operation the `sender' is now also the
5231 client entry of the sender not the nickname.
5233 Affected file is lib/silcclient/ops.h and all applications
5234 using the client operations.
5236 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5238 * Moved the calling of ops->connect() from connect_to_server_final
5239 into receive_new_id functin since that is the point when the
5240 client is actually allowed to send traffic to network. The
5241 affected file is lib/silcclient/client.c.
5243 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5245 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5246 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5247 (if needs broadcasting) instead of broadcasting the packets one
5248 by one which would make a burst in the network traffic.
5250 * Added `broadcast' argument to the functions in silcd/server.[ch]
5251 silc_server_create_new_channel[_with_id] to indicate whether
5252 to send New Channel packet to primary router.
5254 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Added new function into the silcd/server.[ch] files:
5257 silc_server_create_new_channel_with_id to create new channel with
5258 already existing Channel ID.
5260 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5261 lib/silccore/silcpacket.h. This packet is used t send list of
5262 Set Mode payloads inside one packet. Server uses this to set
5263 the modes for the channels and clients on those channels, that it
5264 announced to the router when it connected to it. The protocol
5265 specification has been updated accordingly.
5267 * The silc_server_new_channel did not handle the packet coming
5268 from normal server as it normally does not send that. However,
5269 when it announces its channels it does send it. Implemented
5270 the support for that.
5272 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5273 into the file lib/silccore/id.h.
5275 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * Fixed memory leaks in the functions silc_idlist_del_client,
5278 silc_idlist_del_channel and silc_idlist_del_server in the file
5279 silcd/idlist.c. All of those leaked like a sieve.
5281 * Fixed some small memory leaks in the client's function
5282 silc_client_notify_by_server.
5284 * Added functions into silcd/server.c: silc_server_announce_clients,
5285 silc_server_announce_channels and silc_server_announce_server.
5286 These functions are used by normal and router server to announce
5287 to its primary router about clients, channels and servers (when
5288 router) that we own. This is done after we've connected to the
5291 These functions effectively implements the following packet types:
5292 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5293 and SILC_PACKET_NEW_ID_LIST.
5295 * Added new functions into the silcd/packet_receive.[ch]:
5296 silc_server_new_id_list, silc_server_new_channel_list and
5297 silc_server_new_channel_user_list to handle the incoming
5298 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5300 * Added support of changing Channel ID in the function
5301 silc_server_replace_id. If the server that announces a channel
5302 to the router already exists in the router (with same name but
5303 with different Channel ID), router is responsible to send
5304 Replace ID packet to the server and force the server to change
5305 the Channel ID to the one router has.
5307 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5308 client that the Channel ID has been changed by the router. The
5309 normal server sends this to the client. Client must start using
5310 the new Channel ID as the channel's ID.
5312 Implemented handling of this new type into lib/silcclient/client.c
5313 into the function silc_client_notify_by_server.
5315 * Added new function silc_idlist_replace_channel_id into the files
5316 silcd/idlist.[ch] to replace the Channel ID.
5318 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Call silc_server_command_identify_check always when processing
5321 the IDENTIFY command in silcd/command.c
5323 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5325 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5326 send keepalive packets. The packet can be sent by clients,
5327 servers and routers.
5329 Added function silc_socket_set_heartbeat into the file
5330 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5331 If not set, the heartbeat is not performed. The actual
5332 heartbeat is implemented in the low level socket connection
5333 library. However, application is responsible of actually
5336 Added silc_server_send_heartbeat to send the actual heartbeat
5337 packet into silcd/packet_send.[ch]. Server now performs
5338 keepalive with all connections.
5340 * Added silc_task_get_first function into lib/silcutil/silctask.c
5341 to return the timeout task with shortest timeout. There was a bug
5342 in task unregistration that caused problems. TODO has been
5343 updated to include that task system must be rewritten.
5345 * The client library will now resolve the client information when
5346 receiving JOIN notify from server for client that we know but
5347 have incomplete information.
5349 * Rewrote parts of silc_server_remove_from_channels and
5350 silc_server_remove_from_one_channel as they did not remove the
5351 channel in some circumstances even though they should've.
5353 * Encryption problem encountered in server:
5355 The LEAVE command used to send the Channel Key packet to the
5356 router immediately after generating it. However, the code
5357 had earlier sent Remove Channel user packet but not immediately,
5358 ie. it was put to queue. The order of packets in the router
5359 was that Channel Key packet was first and Remove Channel User
5360 packet was second, even though they were encrypted in the
5361 reverse order. For this reason, MAC check failed. Now, this
5362 is fixed by not sending the Channel Key packet immediately but
5363 putting it to queue. However, this is more fundamental problem:
5364 packets that are in queue should actually not be encrypted
5365 because packets that are sent immediately gets encrypted
5366 actually with wrong IV (and thus MAC check fails). So, packets
5367 that are in queue should be encrypted when they are sent to
5368 the wire and not when they put to the queue.
5370 However, the problem is that the current system has not been
5371 designed to work that way. Instead, the packet is encrypted
5372 as soon as possible and left to the queue. The queue is then
5373 just purged into wire. There won't be any fixes for this
5374 any time soon. So, the current semantic for packet sending
5377 o If you send packet to remote host and do not force the send
5378 (the packet will be in queue) then all subsequent packets to the
5379 same remote host must also be put to the queue. Only after the
5380 queue has been purged is it safe again to force the packet
5383 o If you send all packets immediately then it safe to send
5384 any of subsequent packets through the queue, however, after
5385 the first packet is put to queue then any subsequent packets
5386 must also be put to the queue.
5388 Follow these rules and everything works fine.
5390 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Added new function silc_server_remove_clients_by_server to
5393 remove all client entries from ID list when the server connection
5394 is lost. In this case it is also important to invalidate all
5395 client entires as they hold the invalid server entry. This
5396 fixes fatal bug when server has lost connection and will reconnect
5399 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Made some sanity checks to silc_server_daemonise like to check
5402 whether the requested user and group actually exists.
5404 * Added sanity check to SKE's silc_ske_responder_finish to check
5405 that the public and private key actually is valid.
5407 * Invalidate the client's nickname when receiving Replace ID
5408 packet and the Client ID is being replaced. This means that the
5409 server will query the nickname if someone needs it (client)
5412 * Sort the ID Cache in client library when the ID Cache data
5413 has changed (needs sorting).
5415 * Do not allow for SILC client to create several connections to
5416 several servers. The client does not support windows right now
5417 and generating multiple connections causes weird behaviour.
5419 Irssi-silc client does support windows and can handle several
5420 connections without problems, see: www.irssi.org and SILC plugin.
5422 * Fixed some places where client was added to the IDList. The
5423 rule of thumb is following (in order to get everything right):
5424 If the client is directly connected local client then the
5425 `connection' argument must be set and `router' argument must be
5426 NULL to silc_idlist_add_client function. If the client is not
5427 directly connected client then the `router' argument must
5428 bet set and the `connection' argument must be NULL to the
5429 silc_idlist_add_client function.
5431 * The funtion silc_server_packet_send_local_channel actually did
5432 not check whether the client was locally connected or not. It
5433 does that now. Fixed a bug related to LEAVE command.
5435 * Fixed Remove Channel User payload parsing bug in server's
5436 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5438 * The server's silc_server_save_channel_key now checks also the
5439 global ID list for the channel as it might not be in the local
5440 list. Fixed a bug related to LEAVE command.
5442 * Is this the end of the [<unknown>] buglet that has been lurking
5443 around for a long time? A little for loop fix in server's
5444 silc_server_command_whois_parse that is used by both IDENTIFY
5445 and WHOIS command. At least, this was a clear bug and a cause
5446 of one type of [<unknown>] buglet.
5448 * WHOIS and IDENTIFY commands call the function
5449 silc_server_command_[whois/identify]_check function even if
5450 we are not router server.
5452 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added --with-gmp configuration option. If set the GMP
5455 is always compiled in the SILC source tree. If not set then
5456 it is checked whether the system has the GMP3 installed. If
5457 it has then the GMP won't be compiled (the system's headers
5458 and library is used), if it doesn't have it then the GMP is
5459 compiled in the SILC source tree.
5461 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Changed RSA private exponent generation to what PKCS #1
5464 suggests. We try to find the smallest possible d by doing
5465 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5466 not security fix but optimization.
5468 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Added new config entry [Identity] to fork the server and run
5471 it as specific user and group. A patch from Bostik.
5473 * Imported Dotconf configuration library into lib/dotconf.
5474 This will be used to create the SILC configuration files later.
5475 It will appear in the distsribution after this commit.
5477 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * A big code auditing weekend happening. Auditing code for
5480 obvious mistakes, bugs and errors. Also, removing any code
5483 Removed files for being obsolete:
5485 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5486 inline in the file lib/silcutil/silcbuffer.h)
5488 o lib/silcutil/silcbufutil.c (the header has inline versions)
5490 Changed code to fix possible error conditions:
5492 o The buffer formatting routines now check that the destination
5493 buffer really has enough space to add the data. This applies for
5494 both buffer formatting and unformatting
5495 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5496 unformatting was changed to accomodate following rules:
5497 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5498 sent to the function while XXX_*STRING will not allocate or copy
5499 the data into the buffer. Instead it sets the pointer from the
5500 buffer into the pointer sent as argument (XXX_*STRING used to
5501 require that the pointer must be allocated already). This change
5502 makes this whole thing a bit more consistent and more optimized
5503 (note that the data returned in the unformatting with XXX_*STRING
5504 must not be freed now). The routines return now -1 on error.
5506 o Tried to find all code that use buffer_format and buffer_unformat
5507 and added return value checking to prevent formatting and
5508 especially unformatting errors and possible subsequent fatal
5511 o Changed ske->x and ske->KEY to mallocated pointers in
5512 lib/silcske/silcske.h. Fixed possible data and memory leak.
5514 o Added return value checking to all *_parse* functions. Fixed
5515 many memory leaks as well.
5517 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5518 so that buffer overflows would not happen. All code now also
5519 checks the return value as it can fail.
5521 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5523 * Added reconnection support to server if the normal server looses
5524 its connection to the router (for example if router is rebooted).
5525 The server performs normal reconnection strategy implemented
5526 to the server. Affected file silcd/server.c.
5528 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Added new packet type SILC_PACKET_SET_MODE that is used to
5531 distribute the information about changed modes (for clients,
5532 channels and clients channel modes) to all routers in the
5533 network. Updated the protocol specification accordingly.
5535 Added functions into silcd/packet_send.c and
5536 silcd/packet_receive.c: silc_server_send_set_mode,
5537 silc_server_set_mode.
5539 Added new files silcmode.[ch] into lib/silccore that implements
5540 the encoding and decoding of Set Mode Payload. Added new type
5541 SilcSetModePayload. Moved the definitions of different modes
5542 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5544 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Oops, a little mistake in server's connection authentication
5547 protocol. The protocol is not ended with FAILURE but with
5548 SUCCESS if the authentication is Ok. :) Affected file is
5551 * Implemented NICK_CHANGE notify handling in server in the file
5552 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5553 the local clients on the channel. After the changing nickname
5554 in router environment snhould work and the [<unknown>] nickname
5555 should appear no more.
5557 The silc_server_replace_id function that receives the Replace ID
5558 payload now sends the NICK_CHANGE notify type also in the file
5559 silcd/packet_receive.c
5561 * Changed WHOIS and IDENTIFY command to support the maximum amount
5562 of arguments defined in protocol specs (3328 arguments). This
5563 fixed a bug that caused problems when there were more than three
5566 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Added extra parameter, command identifier, to the
5569 silc_client_send_command so that explicit command identifier
5572 Changed that ID list routines uses specific command identifier
5573 when sending WHOIS/IDENTIFY requests to the server so that they
5574 can be identified when the reply comes back.
5576 Affected files lib/silcclient/command.[ch],
5577 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5579 * Added `sender' argument to silc_server_packet_send_to_channel
5580 to indicaet the sender who originally sent the packet to us
5581 that we are now re-sending. Ignored if NULL. Affected file
5582 silcd/packet_send.[ch].
5584 * Added some server statistics support in silcd/server_internal.h
5585 SilcServerStatistics structure and around the server code. Also
5586 send some nice statistics information when client is connecting
5589 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Fixed channel ID decoding in server's JOIN command reply in
5592 silcd/command_reply.c
5594 * Fixed braodcasting of replace ID payload to not to send it if
5595 we are standalone server in silcd/packet_receive.c.
5597 * Fixed all channel message sending routines to not to send
5598 packets to clients that has router set, since they are routed
5599 separately in the same function earlier. Affects file
5600 silcd/packet_send.c and all channel packet sending functions.
5602 * In USERS reply, res_argv[i] are not allocated, the table
5603 is allocated. Thus changed that free the table, not its
5606 * In server's whois_check and identify_check if the client is
5607 locally connected do not send any WHOIS commands - they are not
5610 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Fixed some minor bugs in client when sending WHOIS command. The
5613 arguments was in wrong order.
5615 * Removed statis function add_to_channel from server in
5616 silcd/command.c that was previously used with the joining but
5619 * Tested USERS command in router environment successfully with two
5620 routers, two servers and two clients.
5622 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Reorganized the USERS command and command reply in client library
5625 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5626 When the command is given by user we register a pending command
5627 callback that will reprocess the command after the reply has been
5628 received from the server. When reprocessing the packet we then
5629 display the information. Thus, the USERS information is displayed
5630 now in the command callback instead of in the command reply
5631 callback. The processing of the command is same as previously
5632 when server has sent the command reply in the JOINing process.
5634 * Added to USERS command in silcd/command_reply.c to join the client,
5635 we didn't use to know about, to the channel after we've created
5636 a client entry for it. Also, for clienet we did know already still
5637 check whether it is on the channel or not and add it if not.
5639 * Removed silc_server_command_join_notify as the function and its
5642 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Changed the client's pending command handling to the same as the
5645 server's pending command handling. It is also now possible to
5646 execute command reply functions from other command reply
5647 function as the function callbacks for commands and command
5648 replies are one and same. The pending commands are not static
5649 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5650 in client connection context. Thus, pending commands are server
5651 connection specific as it is convenient.
5653 Changed the function silc_client_command_pending and
5654 silc_client_command_pending_del and added new function
5655 silc_client_command_pending_check. Removed the
5656 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5659 * Added cmd_ident, current command identifier, to the client
5660 connection context in lib/silcclient/client.h to keep track on
5661 command identifiers used in command sending. Client's command reply
5662 function handling now supports the mandatory command identifiers.
5664 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5665 funtions in client to fully support pending command callbacks.
5667 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5668 as one of the arguments to the application in the command reply
5671 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5672 before first releasing SILC but came back. Now it is removed again
5673 and should come back nomore. The FORWARDED flag was used only
5674 by the JOINing procedure by forwarding the command packet to router.
5675 Now, the JOINing procedure has been changed to more generic (due
5676 to various router environment issues) and FORWARDED is not needed
5677 anymore for anything. The protocol specification is yet to be
5680 Now, removed silc_server_packet_forward from server and the flag
5681 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5683 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Renamed NAMES command to USERS command. The NAMES was named that
5686 due to historical reasons. Now it is renamed. Also, rewrote
5687 parts of the USERS command. The nickname list is not sent anymore
5688 by the server. Only Client ID and mode lists are sent in the USERS
5689 command. Changed this also to the protocol specification.
5691 The client now resolves the names and stuff after it receives
5692 the USERS list from the server when joining to the channel.
5694 * WHOIS and IDENTIFY commands has been changed to support multiple
5695 Client ID's per command. One can now search for multiple users
5696 in the network by sending only one WHOIS or IDENTIFY command.
5697 Changed the code and the protocol specifications.
5699 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5700 uses silc_server_command_whois_parse to parse the request. */
5702 * If normal server, do not parse the WHOIS and IDENTIFY requests
5703 before sending it to the router. Saves some time.
5705 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Fixed JOIN command on client library. Wrong number of arguments
5708 used to crash the client.
5710 * Added silc_server_channel_has_global function to check whether
5711 channel has global users or not.
5713 * Added silc_server_channel_has_local function to check whether channel
5714 has locally connected clients on the channel.
5716 * The silc_server_remove_from_one_channel now checks whether the
5717 channel has global users or not after given client was removed from
5718 the channel. It also checks whether the channel has local clients
5719 on the channel anymore. If it does not have then the channel entry
5720 is removed as it is not needed anymore.
5722 * The silc_server_notify now checks on JOIN notify whether the joining
5723 client is one of locally connected or global. If it is global then
5724 the channel has now global users on the channel and that is marked
5725 to the channel entry. Also, it now saves the global client to
5726 global list who is joining and JOINs it to the channel. This is
5727 for normal server, that is.
5729 Changed silc_server_send_notify_on_channel,
5730 silc_server_packet_relay_to_channel and
5731 silc_server_packet_send_to_channel check if we are normal server
5732 and client has router set (ie. global client) do not send the
5733 message to that client, as it is already routed to our router.
5735 * Implemented LEAVE notify type handling in silc_server_notify
5738 * Tested LEAVE command in router environment successfully. Tested
5739 with two routers, two servers and two clients.
5743 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5745 * Implemented SIGNOFF notify type handling in silc_server_notify
5748 * silc_server_remove_id now removes the client entry from all channels
5749 it has joined and thusly sends SIGNOFF notify type.
5751 * Rewrote the NAMES list generation in server by removing two excess
5752 loops. The lists are created now inside one loop.
5754 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * silc_server_remove_channel_user checks now also global list
5757 for channel and client.
5759 * silc_server_new_channel_user checks now both local and global
5760 list for channel and client. Fixed a bug in client id decoding.
5761 Used to decode wrong buffer.
5763 * silc_server_channel_message checks now both local and global
5764 list for channel entry.
5766 * Tested channel joining (hence JOIN) in router environment
5767 successfully. Tested with two routers, two servers and two
5770 * Tested channel message sending in router environment successfully.
5772 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added silc_server_save_channel_key into server.[ch] to save the
5775 received channel key in Channel Key payload processing. It is
5776 also used in JOIN command reply handling.
5778 Equivalent function silc_client_save_channel_key added into
5779 client.[ch] into client library.
5781 * Changed JOIN command reply to send information whether the channel
5782 was created or not (is existing already) and the channel key
5783 payload. Changed protocol specs accordingly.
5785 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5786 the request was sent by ID and not by nickname. Crashed on
5789 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5792 now correctly save the received data.
5794 * silc_server_free_sock_user_data now notifies routers in the
5795 network about entities leaving the network.
5797 At the same time implemented functions silc_server_remove_id
5798 and silc_server_send_remove_id to receive and send REMOVE_ID
5799 packets. The packet is used to notify routers in the network
5800 about leaving entities. The ID removed will become invalid in
5803 * Added function silc_idlist_del_server into server. Removes and
5804 free's server entry from ID list.
5806 * silc_server_private_message function now checks, if we are router,
5807 that the destination ID really is valid ID, naturally.
5809 * In router when NEW_ID packet is received (for new client) the
5810 hash of the Client ID is saved in the ID Cache but the
5811 client->nickname is set to NULL, instead of putting the hash
5814 IDENTIFY command now also checks that client->nickname must be
5815 valid. If it is not if will request the data from the server who
5816 owns the client. Added new function
5817 silc_server_command_identify_check.
5819 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5820 to set the command to already allocated Command Payload.
5822 * Tested private message sending in router environment with two
5823 routers, two servers and two clients. Fixed minor bugs and now
5826 * Fixed segfault from client's NAMES command. Used to crash if
5829 * Forwarded packets must not be routed even if it is not destined
5830 to the receiver. Changed server code comply with this.
5832 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Added `require_reverse_mapping' boolean value to ServerParams
5835 structure. If TRUE (not default) the server will require that
5836 the connecting host has fully qualified domain name.
5838 If the reverse mapping is not required and hostname could not be
5839 found the IP address is used as hostname.
5841 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Implemented version string checking to both client and server.
5844 The check is incomplete currently due to the abnormal version
5845 strings used in development version of SILC.
5847 * Changed all command functions in server to use the new
5850 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Changed char *data to unsigned char *data in ID Cache system to
5853 support binary data as ID Cache data. Changed code to support
5854 binary data in lib/silccore/idcache.c.
5856 * Renamed silc_server_packet_relay_command_reply to
5857 silc_server_command_reply as it is normal packet receiving
5858 function. Rewrote the function to accept command replys for
5859 servers and not only for clients.
5861 * Mark remote router always as registered server if we are connecting
5862 to it. Otherwise, commands sent by the router to us are ignored.
5864 * All ID List find routines now returns the ID Cache Entry pointer
5865 as well if requested.
5867 * WHOIS command works now in router environment, tested with two
5868 routers, two servers and two clients.
5870 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5871 in router environment (as it is almost equivalent to WHOIS) but
5872 hasn't been tested thoroughly. Added new functions:
5874 silc_server_command_identify_parse
5875 silc_server_command_identify_send_reply
5876 silc_server_command_identify_from_client
5877 silc_server_command_identify_from_server
5879 * Disabled route cache adding because adding two different ID's with
5880 same IP replaces the old cache entry thus giving wrong route.
5881 The entry->router->connection is always the fastest route anyway
5882 so route cache may not be needed. Of course, new routes maybe
5883 established after receiving the ID when the entry->router->connection
5884 might not be anymore the most optimal.
5886 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Add route cache for received ID for fast routing.
5890 * Added silc_server_packet_route to route received packet on router
5891 that is not destined to us.
5893 * Renamed silc_server_get_route to silc_server_route_get.
5895 * Added id_string and id_string_len fields into SilcServer to
5896 include encoded ServerID for fast comparing without excess
5897 encoding of the ID's.
5899 * Cleaned up WHOIS command on server side. Added following static
5902 silc_server_command_whois_parse
5903 silc_server_command_whois_check
5904 silc_server_command_whois_send_reply
5905 silc_server_command_whois_from_client
5906 silc_server_command_whois_from_server
5908 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5909 arguments in command replies. All command functions should be
5910 updated to use this macro.
5912 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Minor typo fixes on command reply handling on server.
5916 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added silc_server_command_add_to_channel internal routine to add
5919 the client to the channel after router has created the channel and
5920 sent command reply to the server.
5922 * Added generic silc_server_send_command to send any command from
5925 * Use static buffer with ID rendering instead of duplicating data.
5927 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Fixed a channel user mode bug when joining to a channel server gave
5930 everybody channel founder rights, oops.
5932 * We mark ourselves as the router of the incoming server connection
5933 if we are router ourselves. This way we can check in some packet
5934 sending functions whether it is locally connected server. For
5935 incoming router connections we put NULL.
5937 * For router sending packets locally means now always sending the
5938 packet cell wide; to local clients and local servers. For normal
5939 server sending packet locally means sending it to only local
5942 * Fixed the JOIN command to really work in router environment. If the
5943 channel is created it is always created by the router. Router is
5944 also responsible of making the initial joining to the channel,
5945 sending JOIN notify to the sending server and distributing
5946 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5947 does not exist server doesn't do anything else but forward the
5948 command to the router which performs everything.
5950 * Added silc_server_send_channel_key function to send the Channel Key
5953 * Added silc_server_create_channel_key to create new channel key. The
5954 channel key is now re-generated everytime someone joins or leaves
5955 a channel, as protocol dictates. Note: channel->key_len is the
5958 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5961 packet_receive.[ch] to separate packet sending and receiving
5962 routines. The server.[ch] now includes everything else including
5963 actual packet processing (writing and reading data) and other
5966 Renamed silc_server_private_message_send_internal to
5967 silc_server_send_private_message. The routine is still though
5968 used only to relay private messages as server does not send
5969 private messages itself.
5971 Renamed silc_server_new_channel to silc_server_create_new_channel
5972 and added new function sicl_server_new_channel that handles the
5973 incoming New Channel packet. Added also new sending function
5974 silc_server_send_new_channel to send New Channel Payload.
5976 * Added new function silc_server_notify to process incoming notify
5977 packet to the server/router. Server may then relay the notify
5978 to clients if needed.
5980 * Added new function silc_server_new_channel_user to process incoming
5981 New Channel User packet. Router will redistribute the packet and
5982 send JOIN notify to its local clients and locally connected servers
5983 if needed. Normal server will send JOIN notify to its local client
5984 on same channel when received this packet. Added also corresponding
5985 sending function silc_server_send_new_channel_user to sent the
5988 * Added boolean route argument to send_notif_to_channel and
5989 packet_send_to_channel functions to attempt to route the packet
5990 if it is TRUE and send only locally if it is FALSE.
5992 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * silc_server_replace_id now broadcasts the received replace ID
5995 packet if it is not broadcast packet already. The router must
5996 broadcast to inform other routers about changed ID.
5998 * Added backpointer to server's router into SilcServer context in
5999 silcd/server_internal.h.
6001 * Fixed silc_server_packet_broadcast to send correct broadcast
6004 * The channel key is now distributed to the local client as soon
6005 as it is received from the router (in router environment) so that
6006 no other packet may be sent for the channel until client has
6009 * silc_server_remove_channel_user now broadcasts the received
6010 Remove Channel User packet if it is not broadcast packet already.
6011 The router must broadcast to inform other routers about removed
6014 * Added users field into SilcPacketContext that is a reference count
6015 of the context. One can increase the reference count by calling
6016 silc_packet_context_dup which is now changed to just increase the
6017 reference count instead of duplicating the data. The reference
6018 count is decresed by calling silc_packet_context_free that will
6019 free the data after the reference count hits zero.
6021 For now on the packet context and everything allocated into it
6022 (including the raw packet from network) must be freed by calling
6023 the new silc_packet_context_free function. Added also new function
6024 silc_packet_context_alloc that must be used now to allocate the
6025 context. This also means that if a routine is asynchronous from
6026 silc_[client/server]_packet_parse_type the packet context must
6027 be duplicated by calling silc_packet_context_dup. Otherwise it
6028 gets free'd after silc_[client/server]_packet_parse_type returns.
6029 Also, one must remember that if packet is duplicated then its
6030 reference count must be decresed by calling the free function as
6031 many times as it was duplicated.
6033 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6034 from both client and server.
6036 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Made joining to a channel working in router environment.
6040 * Cleaned up JOIN command on server side and create function
6041 silc_server_command_join_channel internal routine to make the
6044 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6046 * Changed silc_command_pending list to SilcDList. Also, added
6047 `ident' field to SilcServerCommandPending structure to identify
6048 the reply and to call correct callback.
6050 Added silc_server_command_pending_check function to replace the
6051 corresnponding macro. The silc_command_pending list is not
6054 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6055 to set identifier to previously allocated Command Payload. It
6056 is used to set identifier for command when resending Command
6059 * Added silc_command_payload_encode_payload to encode Command
6060 Payload buffer from SilcCommandPayload structure.
6062 * Added silc_argument_payload_encode_payload to encode Argument
6063 payload buffer from SilcArgumentPayload structure.
6065 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Changed WHOIS command to support router connection on server side.
6068 The whois request is always sent to router unless the server is
6069 standalone server. After server has received the reply from the
6070 router will it send the reply to the client.
6072 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6073 broadcast received broadcast packet. The function is used only
6074 by router. The broadcast packet is always sent to the router's
6077 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6078 render given ID to printable string, for log files for example.
6080 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Made basic router to router connections working. At least they
6083 can now connect to each other but nothing really works the way
6084 they are supposed - yet.
6086 * Added new initiator token to RouterConnection configuration
6087 file in silcd/serverconfig.[ch]. It is used to tell whether we
6088 are the initiator to the remote router or whether we'll expect
6089 the other end to connect.
6091 * Moved registering of listener task to silc_server_init, hence
6092 the server starts listenning as soon as it is run, even if it
6093 does not have connections to other routers. Let's see how well
6096 * Changed default connection retry timeouts for more suitable in
6099 * Removed cipher and such arguments from silc_idlist_add_client
6100 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6101 Added new function silc_idlist_add_data to add the keys and stuff
6104 * Added SilcIDListData structure and added it to SilcClientEntry
6105 and SilcServerEntry as their first field in the structure. This
6106 way we can explicitly cast the ID entries to the SilcIDListData
6107 structure and get common data for the entries. In past, we had
6108 to first check what type of connection it is and then cast it to
6109 correct ID entry type. Now, we can directly cast the opaque
6110 pointer to the SilcIDListData (no matter what ID entry it actually
6111 is) and get the data needed.
6113 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6116 in some circumstances even if threre were timeout tasks, though not
6117 IO tasks, but tasks anyway. Now fixed.
6119 * Defined SilcServerConnection structure to hold connection specific
6120 stuff about directly connected servers and routers. The definition
6121 is currently in silcd/server_internal.h. I thought about having
6122 a bit more important role fro this struct but for now it is used
6123 only when connecting to other server (or router actually).
6125 * Added connecting retry support in server when connecting to
6126 router(s). The retry feature implement exponential backoff
6127 algorithm. Also, added SilcServerParams structure to hold default
6128 parameters for server. For now, it include these retry settings
6129 and are hard coded. After server is moded to be as Silc Server
6130 Library this structure will be more important.
6132 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Changed client librarys channel->clients table to SilcList and
6135 changed code accordingly.
6137 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6139 * Changed client's channel table to SilcList and changed code
6140 accordingly. Also changed SilcChannelClientEntry to include back-
6141 pointer to the channel so that client entry can use that structure
6142 as list as well and we have fast cross-reference to the channel.
6143 This change dramatically decreased the complexity of channel
6144 handling with client entry and vice versa (removed one extra
6145 loop when searching for channel entry from many functions).
6147 * Changed server->sim from table to SilcDList and changed code
6150 * NAMES command can now be used from user interface. It will show
6151 the user list on the channel, neatly.
6153 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6154 Code now saves realname of the user if it becomes available.
6156 * Renamed configure.in to configure.in.pre and made ./prepare
6157 script to automatically add correct version string to
6158 configure.in which it creates from configure.in.pre.
6160 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * NAMES command reply now shows users mode with the nickname when
6165 * Moved silc_client_ch[u]mode[_char] functions from
6166 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6167 place sucks, they are utility functions and should be in some
6170 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6172 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6175 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added TRQ (efficient deque and list library) into lib/trq. This is
6180 a very good list library that is currently used in the SILC. Defined
6181 SilcList API over the library because I didn't like the API very
6182 much. See lib/trq/silclist.h for the API and examples of how to
6183 use the API. Fixed various places in the code to use the new
6184 SilcList API. The SilcList is meant for lists that has a structure
6185 already defined as a list. It is not suitable to add just some
6186 context to the list (in TRQ, the context is the list actually).
6188 So, I defined SilcDList that can be used for the purpose where
6189 predefined list structure does not exit. This can be used as
6190 such list. Now some context just can be added to the SilcDList.
6191 Currently this list is not used in the SILC just yet, though there
6192 are a lot places where this can replace dynamically allocated
6193 tables and I will fix these places, later, to use SilcDList.
6194 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6195 and use TRQ internally).
6197 Also fixed some annoying warning messages that the original TRQ
6198 code generated. Also minor changes to TRQ's Makefile.in.
6200 * Added support for querying by Client ID to both WHOIS and
6201 IDENTIFY commands into server, as required by the protocol.
6203 * Removed method function pointers from SilcBuffer structure. They
6204 weren't used to anything and just increased the context size for
6205 no good reason. This change also made silc_buffer_alloc and
6206 silc_buffer_free functions inline functions.
6208 * Disabled command flooding detection support until it's fixed so
6209 that it accepts commands in but does not execute them more than once
6212 * Added silc_net_localhost(), to return local hostname, into
6213 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6214 that must be initialized before calling silc_client_init.
6216 * Added new function: silc_server_send_notify_on_channels to send
6217 notify messages to all channels client has joined. It is assured
6218 that the message is sent only once per client.
6220 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6221 lib/silcutil/silcutil.[ch] as silc_format function. The new
6222 function is generic and is used by server as well, not only by
6223 the logging routines.
6225 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6226 the provided version string was not acceptable. Added new function:
6227 silc_ske_check_version into lib/silcske/silcske.h. The function
6228 must be implemented by the application (client or server) and it
6229 does not reside in the SKE library. The function checks the version
6230 string remote end sent.
6232 * Added back pointers (to opaque context and to SilcSocketConnection)
6233 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6235 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6236 duplicate packet context structure.
6238 * Changed `notify' client operation to send same arguments as client
6239 receives from server except for ID's. ID's are mapped to correct
6240 ID entry and that is returned. Also, if channel entry is not sent
6241 by server but the notify is for channel the channel entry is sent
6242 to application (otherwise application doesn't know that it is for
6243 channel (library gets it from packet's Destination ID)).
6245 * Added silc_client_remove_from_channels into client library to
6246 remove a client from all channels it has joined to. Used when
6247 received SIGNOFF notify from server. Added also new function
6248 silc_client_replace_from_channels to replace old ID entry with
6249 new ID entry on all channels. Used when received NICK_CHANGE
6252 * Fixed ID Cache list handling in silc_idlist_get_client in
6253 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6254 to get (or query) client by ID.
6256 * Updated TODO list.
6258 * Added connection authentication status message defined by the
6259 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6260 support for these into the code in client and server side.
6262 * Added generic function silc_client_send_command to send any command
6263 with variable argument list. Application should use this function
6264 to send commands if the command functions provided by the library
6265 does not suite for the application's user interface needs.
6267 * Added new `failure' client operation. Application is notified about
6268 received failure packet if client is executing a protocol. In this
6269 case the protocol's execution has failed.
6271 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6272 is required by the protocol.
6274 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6275 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6278 * Added status flag to SilcSKE object to indicate realtime status
6279 of the SKE protocol.
6281 * Application receives now exactly same command reply arguments as
6282 the library receives from server. However, if ID is received the
6283 corresponding ID entry is returned to the application (eg. Client
6284 ID is mapped to correct SilcClientEntry entry and that is returned).
6285 Changed command_reply client operation due to this change.
6287 * Changed all ID's in commands and in command replys as ID Payloads.
6288 Change affected both client and server side codes.
6290 All ID's sent in SILC network (with execption of ID's in SILC
6291 Packet header) are sent in ID Payload to support variable length
6294 * Server now notifies nick changes and notifies all clients on
6295 the channels about the new nickname (about the new Client ID,
6298 * Implemented CMODE command to change channel modes. Supports all
6299 channel modes defined by the protocol specs except ban and invite
6300 lists. (Also, private channel key mode is supported but support for
6301 setting private channel key in client is missing, thus, this mode
6302 has no effect on client side (except that server requires that the
6303 client uses private channel key and normal channel traffic does not
6306 Also, invite mode works per se, but INVITE command does not work
6307 yet correctly, so you can set channel as invite only channel but
6308 inviting clients to the channel does not work (it is yet to be
6309 thought what's the best way to do it).
6311 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6312 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6313 Implemented CUMODE command to change user's mode on the channel.
6314 Supports all modes defined by the protocol specs.
6316 * Added NAMES command reply to return users modes on the channel.
6318 * Removed unnecessary and slow ciphers from lib/silccrypt.
6320 * Set SO_KEEPALIVE option to connection sockets by default.
6322 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6324 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6325 redefined the Notify Payload into protocol specs.
6327 * Added silc_id_payload_parse_id to get ID directly from raw
6330 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6333 accept searching by Client ID as well.
6335 * Added support for LEAVE and SIGNOFF notify types in client library.
6337 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6338 to parse ID Payload from raw data.
6340 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Added flags parameter into silc_ske_assemble_security_properties
6343 function in lib/silcske/silcske.[ch].
6345 * Changed notify client operation to fit better for notify messages
6346 sent by server. The notify payload received from server is now
6347 passed to the application (after parsing it to SilcNotifyPayload).
6348 It is application's responsibility to retrieve the arguments
6349 from the payload and show the message the way it wants. The message
6350 sent by server is implementation specific.
6352 * Changed public keys to comply with the protocol specification.
6353 Old public keys are not supported anymore and are not compatible.
6355 * Removed nickname from Channel Payload as the latest draft removed
6356 it. The client must resolve the nickname from the NAMES command
6357 reply received when it joined the channel.
6359 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6361 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Fixed some errors in protocol specification drafts.
6365 * Created lib/silccore/silcnotify.c to implement Notify Payload
6366 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6367 generic payloads described by protocol specifications. The file
6368 includes implementations for ID Payload and Argument Payload.
6370 * Changed Command Payload implementation to use the new Argument
6371 Payload. Changed command_xxxx_payload to command_payload_xxxx
6372 to comply with SILC coding conventions.
6374 * Added suppport for Argument Payload handling in Notify Payload
6375 implementation as protocol requires it. Added the new support
6376 into server and client lib as well.
6378 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Added support for multiple nicknames on same channel. [n] is
6381 added locally to the nickname if there are more than one same
6382 nicknames on the channel.
6384 * Server now sends all nicknames that matched WHOIS request.
6385 Client also shows the list received from server.
6387 * Added TOPIC command to client side. User can now set and show
6388 current topic on channel.
6390 * Added MOTD command to client and server. Also, server sends the
6391 motd when client connects to the server.
6393 * Changed version strings to comply ISO 8601.
6395 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6397 * Fixed protocol error handling in client library. It should now
6398 cope even if the SKE fails for some reason.
6400 * Made new protocol specification drafts for submitting to IETF.
6402 * Implemented TOPIC command to server in silcd/command.c.
6404 * Added two new notify types into lib/silccore/silcnotify.h:
6405 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6406 notify nickname change and topic setting/change on a channel.
6408 * API change of command_reply operation in client library. The
6409 application gets now the status type received from server as well.
6411 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6415 * Cras fixed and optimized the packet handling even further and
6416 it should work now. Minor change to the prototype of function
6417 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6419 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Added new function into lib/silcutil/silcschedule.[ch]:
6422 silc_schedule_with_fd to select() a specified fd. The function
6423 returns after timeout expires or data arrives or goes. The
6424 function is used by packet routines to wait that all data is
6425 received from network.
6427 * Fixed data reading from network in lib/silccore/silcpacket.c.
6428 The code now assures that all data is read from the fd and then
6429 continues packet processing. This was a bug fix since the code
6430 used to drop some data in some circumstances.
6432 * Added new function into lib/silcclient/client.[ch]:
6433 silc_client_start_key_exchange to start key exchange after
6434 connection has been established to server. The code internally
6435 now uses this funtion but its main purpose was to provide it
6436 for applications that perform their own connecting. After
6437 application has created a connection it merely calls this
6438 function to start the key exchange between client and server.
6439 The library takes care of everything else after that.
6441 Updated also lib/silcclient/README to explain the usage of
6444 * Do not send to application information that connection has
6445 been established. Application gets notified it by connect
6448 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Applied cras's patch to add silc_schedule_one function. The
6451 function runs scheduler once and returns.
6453 * Fixed the scheduler after cras messed it up. The timeout
6454 handling works now as it's supposed to work.
6456 * Added into lib/silccore/ silcnotify.h to include notify
6457 message types support. Changed silc_server_send_notify*
6458 functions, in server.[ch], to support those new notify types.
6459 Added the support for the notify types into client library,
6460 as well. Added new notify client operation into ops.h in
6463 * Changed silc_server_packet_send_to_channel to send normal
6464 packets instead of just channel message packets. The function
6465 is now used to send the notify packets to channels. It is not
6466 used to send channel message packets anymore, as server never
6469 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6470 va_arg()s as it seems to require it nowadays. I guess, if SILC
6471 is compiled with older va_arg() the new code should work anyway.
6473 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * Splitted core library. Core library (lib/silccore) includes
6476 now only SILC protocol specific core (and common) components.
6477 Created new utility library (lib/silcutil) that includes more
6478 generic purpose stuff. The stuff for util library was taken
6479 from the old core library. This was minor and easy split.
6481 * Created SILC Client Library (lib/silcclient) that includes
6482 implementation of the SILC client without user interface. This
6483 was major move from silc/ directory. The code has been changed
6484 so that it is transparent towards the user interface. The
6485 silc/ directory includes now the same user interface as before
6486 and it uses the new client library. Read lib/silcclient/README.
6487 Basicly, the client library performs everything else related
6488 to SILC except user interface handling. Also, configuration
6489 files are considered to be part of user interface and library
6490 does not handle them.
6492 This change also changed a lot of structures, function naming etc.
6493 Most important change was that SilcClientWindow object was
6494 renamed to SilcClientConnection in the client library. Created
6495 also new file lib/silcclient/ops.h. Also added new files
6496 silc/local_command.[ch] and silc/client_ops.[ch].
6498 All these changes were made to make it easier for user interface
6499 designers to create what ever user interface for the SILC client
6502 It is also expected that the server will be moved to lib
6503 directory as well and SILC Server Library will be created;
6504 sometimes in the future.
6506 * Removed Local commands from lib/silccore/silccommand.h as
6507 they are application specific and new client library does not
6508 handle any of those anymore.
6510 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6511 old client implementation in silc/.
6513 * Added support for callback functions in SILC_LOG_* macros.
6514 Application can now set its own callbacks that will be called
6515 instead of using the default functions that will always print
6516 the debug messages to stderr (or stdout). Also, debugging can
6517 now be disabled by setting silc_debug to FALSE and re-enabled by
6518 setting it to TRUE. Note, that logging will still work even
6519 if debugging is disabled.
6521 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6522 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6523 silc_log_reset_debug_callbacks.
6525 * To enable debugging in silc client one must give now -d
6526 option on command line.
6528 * Changed silc_schedule_init to automatically allocate task queues
6529 if they are not allocated before calling it.
6531 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6533 * Added GMP 3.1 into math library.
6535 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6538 a channel in SILC network. The packet is used by servers and
6539 routers to notify other routers that user has left a channel.
6540 This little feature was missing until now. Added the feature
6541 to protocol specification as well.
6543 Added functions: silc_server_send_remove_channel_user and
6544 silc_server_remove_channel_user into server.[ch].
6546 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6547 lib/silccore/silcpacket.h. However, they are not implemented
6550 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Fixed joining to a channel and sending channel messages
6553 between server and router. The channel message sending should
6554 now work inside a cell.
6556 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Fixed the private message sending between server and router.
6559 The private message sending should now work inside a cell.
6561 * Added silc_server_replace_id into server.[ch] to replace
6562 existing ID in the SILC network.
6564 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6565 and silc_idlist_replace_server_id into idlist.[ch] in server.
6567 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Fixed the server to server connections. Server can again now
6570 connect to router. Router to router connections probably does
6573 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Added dynamic protocol registering support. Now protocols can
6576 registered and unregistered on the fly. Patch by cras.
6578 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Added lib/contrib directory to hold routines that some platforms
6581 don't have but are needed by SILC.
6583 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6584 into lin/contrib to provide getopt() and getopt_long() for
6585 those who don't have it.
6587 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6589 * Added AWAY command to client. When away message is set and
6590 client receives a private message packet the client automatically
6591 replies to the sender with the away message.
6593 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6594 bug seemed to be the cause of recent problems when compiling
6597 * Added version detection support to SKE protocol specification
6598 and added the new changes to the SKE implementation as well.
6599 There were other minor changes in the SKE protocol as well.
6601 Many changes in lib/silcske/silcske.[ch] and in
6602 lib/silcske/payload.[ch].
6604 * Added ^U functionality, clear input line. Patch from cras.
6606 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6608 * Mainly small bugfixes on core library. Fixed some debugging
6609 logging and buffer overflow in silclog.c.
6611 * Updated config.sub and config.guess on the distribution tree.
6613 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * Added command lagging support in server. Client may execute
6616 commands now only once in two seconds.
6618 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Optimized packet reception. MAC computation and checking is now
6621 also more optimized. A lot previously duplicated code is now
6622 used as generic by both client and server.
6624 * Fixed key pair generation in clientutil.c
6626 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added into lib/silccore/silcbufutil.[ch] new function;
6629 silc_buffer_realloc.
6631 * Moved generic packet sending/encryption functions to
6632 lib/silccore/silcpacket.[ch] from client and server. Some
6633 rewriting of the functions.
6635 * Moved all generic packet reception/decryption functions to
6636 lib/silccore/silcpacket.[ch] from client and server. The
6637 packet processing is now much cleaner in both client and server.
6638 These were major changes in both client and server.
6640 * Created many common functions in server to do packet sending.
6641 Previously code were duplicated a lot, this has been removed
6644 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Rewrote major parts of the ID cache system. Don't know
6647 whether it is better now or not but at least the API is more
6650 * Major rewrite on ID cache stuff on client because of the ID
6651 cache API changes. Added idlist.c to client.
6653 * Also major rewrite on ID cache stuff on server as well.
6654 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6655 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6656 in hand, instead they are all put into the ID cache system now.
6657 All server_idlist_* routines uses ID cache now instead of
6658 traversing its own lists (those lists does not exist anymore).
6659 SilcIDList though still exists. Also, SilcXXXEntry's are
6662 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6664 * Finally made the SKE implementation compliant to the protocol
6665 specification. All mp integers are now binary encoded as
6666 opposed being HEX encoded.
6668 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6671 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6672 functions: silc_[encode/decode]_pem. Also added function
6673 silc_encode_pem_file to PEM encode with newlines ('\n') for
6676 * SILC public keys are now encoded either PEM or binary. Same
6677 option is for private keys as well. By default private keys
6678 are binary encoded and public keys PEM encoded. Silly HEX
6679 encoding were removed.
6681 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6682 function to create fingerprints.
6684 * Fixed a bug in SHA1; does not change the original data anymore.
6686 * Partly implemented INFO command on client and server side.
6687 Fixed CLEAR command. Changes to SERVER command; show current
6688 server(s) when giving command without arguments. Added
6689 VERSION command to client.
6691 * Added check to server that unregistered connections cannot
6692 execute commands (unless it is specificly allowed).
6694 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * Fixed screen refresh.
6698 * Fixed channel joining bug from client. On some circumstances
6699 client tried to join to a channel it had already joined.
6701 * Added public key verification process into client's protocol.c.
6702 The client now verifies the public key from user and saves
6703 it into ~./silc/serverkeys/ directory.
6705 Added into: clientutil.[ch]: silc_client_verify_server_key.
6707 * Changed SKE protocol's silc_ske_initiator_finish function
6708 to accept callback function that verifies the received public
6709 key. Removed old silc_ske_verify_public_key function.
6711 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6714 silc_pkcs_private_key[_data]_set.
6716 * Made the password and public authentication more cleaner in
6717 server's protocol.c.
6719 * Removed historic and obsolete protocol `channel_auth' from
6720 both client and server.
6722 * Removed wrong way of sending command status messages from
6723 server to client in server's command.c. The old way violated
6724 protocol specification.
6726 Changes to silccore/silccommand.[ch]: removed
6727 silc_command_encode_status_payload -> not needed anymore,
6728 changed silc_command_encode_payload_va to accept extra
6729 argument on variable argument list. The argument type must
6730 now be provided to the function. Also, added new function:
6731 silc_command_encode_reply_payload_va which is same as
6732 normal command_encode_payload_va except command status type
6733 is provided as extra argument.
6735 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Added ~./silc directory handling. The directory includes the
6738 public and private keys for the client.
6740 Added silc_client_check_silc_dir, silc_client_create_identifier
6741 and silc_client_load_keys.
6743 * Implemented SILC protocol compliant public key. Added public
6744 and private key saving to and loading from files.
6746 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6747 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6748 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6749 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6750 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6752 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6753 silc_pkcs_load_[public/private]_key.
6755 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Added silc_server_get_route (route.[ch]) to get connection
6758 data for the fastest route for given ID.
6760 * Implemented INVITE command on client and server. The command
6761 were re-defined in the SILC Protocol Specification and the
6762 implementation now complies with the specification.
6764 * Implemented PING command on client and server.
6766 * Implemented NAMES command on client and server. The server side
6767 supports currently only normal server not router server yet.
6768 Some changes to NAMES definition in SILC protocol specification.
6770 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Implemented LEAVE command on client and server.
6774 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6775 again. This change was made to the protocol as well. Server
6776 should not violate the protocol specification anymore.
6778 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6781 was tested. SOCKS4 was not but should work anyway.
