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

631 to run server on foreground. A patch by debolaz.
632 Affected files silcd/server.c, silcd/silcd.c.
634 * Fixed MOTD to return the MOTD file server name. Affected
635 file silcd/command.c.
637 * Added INFO command reply handling to the Irssi SILC Client.
638 Affected file irssi/src/silc/core/client_ops.c.
640 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
642 * Fixed the silc_idcache_list_* routines to really support
643 the dynamic list. Fixes a crash. Affected file is
644 lib/silccore/silcidcache.c.
646 * Fixed the LIST command reply to really call LIST command's
647 pending callbacks. Affected file silcd/command_reply.c.
649 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
651 * Update conn->local_entry->nickname after giving NICK
652 command. Affected file lib/silcclient/command.c.
654 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
656 * Added the [pid] option to the silcd configuration file
658 Affected files: serverconfig.[ch] and silcd.c
660 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Save fingerprint in WHOIS command reply in server.
663 Affected file silcd/command_reply.c.
665 * Fixed NICK commands pending callback registration.
666 Affected file lib/silcclient/command.c.
668 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
670 * Use ++server->cmd_ident when sending commands in server,
671 instead of random number. Affected file silcd/command.c.
673 * Fixed GETKEY command reply to call actually GETKEY pending
674 command callbacks. Affected file silcd/command_reply.c.
676 * A bit stricter check for nicknames. Check for same nickname
677 in NICK command also. Affected file silcd/command.c.
679 * Do not call INFO command everytime client ID changes, only
680 during first connecting. Affected file lib/silcclient/client.c.
682 * Set the new nickname only after successful command reply for
683 NICK command is returned by server. Affected file
684 lib/silcclient/command.c.
686 * Remove nicknames from nicklist during server_signoff notify.
687 Should fix /NAMES bit more. The affected file is
688 irssi/src/silc/core/silc-channels.c.
690 * Added `fingerprint' field to the SilcIDListData in the
691 silcd/idlist.h to hold the fingerprint of the client's
694 Send the fingerprint of the client's public key in WHOIS
697 Affected files silcd/command.c, and silcd/idlist.[ch].
699 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
700 create fingerprint from given data.
702 * Show the fingerprint of the client's public key in WHOIS.
703 Affected files irssi/src/module-formats.[ch] and
704 irssi/src/silc/core/client_ops.c.
706 * Format the multiple same nicknames also during JOIN and
707 NICK_CHANGE notifys. Affected file is
708 lib/silcclient/client_notify.c.
710 * Do not print error on screen for invalid private message
711 payload since it can come if someone is sending private
712 messages with wrong key. Affected file
713 lib/silccore/silcprivate.c.
715 * Fixed multiple concurrent /PING crash. Affected file
716 lib/silcclient/command.c.
718 * Changed the wrong ID encoding. All IP addresses must be
719 in MSB first order in encoded format. They were encoded
720 wrong and was in LSB format. Affected files are
721 silcd/serverid.c, lib/silcutil/silcutil.c.
723 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
725 * Call the `connect' client operation through the scheduler
726 in case of error. Affected file lib/silcclient/client.c.
728 * Call the `failure' client operation even if the error
729 occurred locally during a protocol. Affected file is
730 lib/silcclient/protocol.c.
732 * Added support of sending LIST command to router from normal
733 server. This way normal server can get list of all channels
734 in the network too. Fixed the channel list sending in the
735 server too. Affected files are silcd/command.c, and
736 silcd/command_reply.[ch].
738 * Added silc_server_update_channels_by_server and
739 silc_server_remove_channels_by_server. They are used during
740 disconnection of primary router and in backup router protocol.
741 Affected file silcd/server_util.[ch], silcd/server.c and
742 silcd/server_backup.c.
744 * Fixed channel adding to global list in IDENTIFY command
745 reply in server. Affected file silcd/command_reply.c.
747 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
749 * If the incoming packet type is REKEY or REKEY_DONE process
750 that packet always synchronously. Fixes yet another MAC
751 failed error on slow (dialup) connections. Affected file
752 lib/silcclient/client.c and silcd/server.c.
754 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
756 * Call check_version SKE callback for initiator too. Affected
757 file lib/silcske/silcske.c.
759 * Implemented fix for security hole found in the SKE that was
760 fixed in the specification few days back; the initiator's
761 public key is now added to the HASH value computation.
762 Added backwards support for the old way of doing it too, for
763 old clients and old servers. Affected file is
764 lib/silcske/silcske.c.
766 * Enabled mutual authentication by default in SKE. If initiator
767 is not providing mutual authentication the responder will
768 force it. This will provide the proof of posession of the
769 private key for responder. The affected files are
770 lib/silcclient/protocol.c and silcd/protocol.c.
772 * Do not cache anymore the server's public key during SKE.
773 We do mutual authentication so the proof of posession of
774 private key is done, and if the server is authenticated in
775 conn auth protocol with public key we must have the public
776 key already. Affected file silcd/protocol.c.
778 * Added new global debug variable: silc_debug_hexdump. If
779 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
780 file lib/silcutil/silclog.[ch].
782 * Fixed compilation warning due to char * -> const char *.
783 Affected files lib/silcutil/silcnet.h, and
784 lib/silccore/silcauth.[ch].
786 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Fixed CMODE command when new channel key was created. If
789 the creation failed the old key was removed. Next time giving
790 same command would crash the server since the old key was
791 freed already. Affected file silcd/command.c.
793 * Fixed the silc_server_announce_get_channels to not crash
794 on reconnect. Affected file silcd/server.c.
796 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
798 * Added silc_log_set_debug_string function to set a regex
799 string to match for debug output. Only the function names,
800 or filenames matching the given debug string is actually
801 printed. This way it is possible to filter out those debug
802 strings that user is not interested in.
804 Fixed a bug in silc_string_regexify.
806 Affected files lib/silcutil/silclog.[ch], and
807 lib/silcutil/unix/silcunixutil.c.
809 * Changed the -d options in both server and Irssi SILC client
810 to take the debug string as argument. Affected files
811 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
813 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Added silc_hash_babbleprint to create a Bubble Babble
816 Encoded fingerprint. The encoding is developed by Antti
817 Huima (draft-huima-babble-01.txt), and it creates human
818 readable strings out of binary data. Affected file
819 lib/silccrypt/silchash.[ch].
821 * Print the babble print now in addition of fingerprint as well
822 in Irssi SILC client. Affected files are
823 irssi/src/fe-common/silc/module-formats.[ch],
824 irssi/src/fe-common/silc/core/client_ops.c.
826 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
828 * Fixed a security problem found in SKE. The initiator's
829 public key too is now added to the HASH hash value creation
830 which is signed by the responder to create the SIGN value.
831 This will prevent anyone in the middle to lie to the responder
832 about the initiator's public key. If this is done now, the
833 man in the middle will get caught. Updated the protocol
836 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Better installation directory handling. Configure module
839 paths and other paths automatically to example_silc* files
840 in doc/. A patch by toma.
842 * Fixed compiler warning from MPI library, and from SILC RNG.
845 * Added SILC_SERVER_PID_FILE to define the pid file for server.
846 It can be configured with ./configure. A patch by toma.
848 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Find correct make to use in prepare-clean. A patch by
851 toma. Affected file prepare-clean.
853 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
855 * Added irssi variables use_auto_addr, auto_bind_ip,
856 auto_bind_port and auto_public_ip.
858 * Changed the interface for silc_client_send_key_agreement
859 in lib/silcclient/silcapi.h
863 irssi/src/silc/core/silc-core.c
865 lib/silcclient/silcapi.h
866 irssi/src/silc/core/silc-channels.c
867 lib/silcclient/client_keyagr.c
870 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
872 * Added silc_pkcs_public_key_compare to compare two
873 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
875 * Check that the client who set the founder mode on the
876 channel is the same client that is giving the founder
877 mode to itself. It is done by comparing the saved public
878 key (it is saved even in the authentication is passphrase).
879 Affected file silcd/command.c.
881 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Do not process packet for disconnected socket connection.
884 Affected file lib/silccore/silcpacket.c.
886 * Process the DISCONNECT packet through scheduler in the
887 client library. Affected file lib/silcclient/client.c.
889 * Fixed the silc_client_packet_parse to not to increase
890 the packet sequence number if the conn->sock and the
891 current socket connection is not same. This can happen
892 for example during key agreement when the conn includes
893 multiple socket connections (listeners). Affected file
894 lib/silcclient/client.c.
896 * The sender of the file transfer request now provides also
897 the pointer (listener) for the key exchange protocol. If
898 the listener cannot be created then it sends empty key
899 agreement and lets the receiver provide the listener.
901 Added `local_ip' and `local_port' arguments to the
902 silc_client_file_send. If they are provided they are used,
903 if not then it will attempt to find local IP address, if
904 not found or bind fails then the remote client will provide
907 Affected files are lib/silcclient/client_ftp.c and
908 lib/silcclient/silcapi.h.
910 * Extended the FILE SEND command to support defining the
911 local IP and port for key exchange listener. They are
912 optional. Affected file irssi/src/silc/core/silc-servers.c.
914 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
916 * Defined to WHOIS command reply the sending of fingerprint
917 of the client's public key (if the proof of posession of the
918 corresponding private key is verified by the server).
919 Updated to the protocol specification.
921 * Added support of receiving the client's public key's
922 fingerprint in command reply in client library. Affected
923 file is lib/silcclient/command_reply.c, and
924 lib/silcclient/idlist.[ch].
926 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Do not send over 128 chars long nickname to the server
929 in NICK command. Affected file lib/silcclient/command.c.
931 * Do not send over 256 chars long channel names to the server
932 in JOIN command. Affected file lib/silcclient/command.c.
934 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Assure that silc_server_close_connection cannot be called
937 twice for same socket context. Affected file is
940 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Send error message to application if opening file for
943 writing during file transfer fails. Affected file is
944 lib/silcclient/client_ftp.c.
946 Remove all file transfer sessions for a client that we're
947 removing from ID cache.
949 Affected file is lib/silcclient/client_ftp.c.
951 * Fixed silc_net_addr2bin to return correct address. Affected
952 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
954 * Fixed file transfer session removing on signoff notify.
955 Affected file irssi/src/silc/core/silc-servers.c.
957 * Added the SilcClientFileError to be returned in the monitor
958 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
959 Affected file lib/silcclient/silcapi.h.
961 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
963 * Fixed a crash in silc_client_ftp_free_sessions and
964 silc_client_ftp_session_free_client. Affected file
965 lib/silcclient/client_ftp.c.
967 * Added `disabled' field in the SilcChannelEntry in the server
968 to indicate if the server entry is disabled. Affected file
969 silcd/idlist.h, silcd/command[_reply].c.
971 * SILC server adds now /var/run/silcd.pid everytime it is
972 started. Affected file silcd/silcd.c.
974 * Added silc_server_packet_send_clients to send a packet to
975 the provided table of client entries. Affected file
976 silcd/packet_send.[ch].
978 * Fixed a crash in client resolving in client_prvmsg.c in
979 client library. Affected file lib/silcclient/client_prvmsg.c.
981 * Do not actually remove the client directly from ID cache
982 during SERVER_SIGNOFF, but invalidate it. This way we
983 preserve the WHOWAS info for the client. Affected file
986 * Fixed SERVER_SIGNOFF notify handling in the server. The
987 server is now able to process incoming SERVER_SIGNOFF notify
988 for a server that it doesn't even know about. It will remove
989 the clients provided in the notify. Affected file
990 silcd/packet_receive.c.
992 * Check for partial packet in data queue after every packet that
993 was found from the queue. Return and wait for more data if
994 there is partial data in queue. Affected file is
995 lib/silccore/silcpacket.c.
997 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Added SilcClietFileError enum to indicate error in
1000 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1001 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1002 Affected files lib/silcclient/silcapi.h and
1003 lib/silcclient/client_ftp.c.
1005 * Check that newsize in silc_buffer_realloc is larger than
1006 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1008 * Added better monitor of file transfers. It now monitors
1009 key agreement protocol during the file transfer too. Added
1010 error reporting too. Affected files
1011 irssi/src/silc/core/silc-servers.c,
1012 irssi/src/fe-common/silc/module-formats.[ch].
1014 * Wrote a help file for FILE command.
1016 * Added silc_rng_global_get_byte_fast to get not-so-secure
1017 random data as fast as possible. Random data is read from
1018 /dev/urandom if available and from the SILC RNG if not
1019 available. It is used in padding generation. Affected file
1020 lib/silccrypt/silcrng.[ch].
1022 * All packets in client library are now processed synchronously.
1023 Optimized packet processing a lot. Affected file
1024 lib/silcclient/client.c.
1026 * All server connection packets are processing synchronously
1027 now in server, to optimize packet processing. Affected file
1030 * Include files are installed now only in Toolkit distribution
1031 if make install is given. Affected files: all Makefile.am's.
1033 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1035 * Assure that silc_client_notify_by_server_resolve does not
1036 resolve the client information multiple times. If it cannot
1037 be found by the first it cannot be found at all. Affected
1038 file lib/silcclient/client_notify.c.
1040 * Fixed WHOWAS command reply calling. Affected file
1041 lib/silcclient/command_reply.c.
1043 * Removed all references to silc_idlist_get_client from the
1044 Irssi SILC client since that call is internal call used by
1045 the library. The Irssi SILC client will use now client
1046 retrieval functions found in silcapi.h.
1048 * Fixed a bug in resolving nickname info before sending
1049 private message. It used freed memory. Affected file
1050 irssi/src/silc/core/silc-servers.c.
1052 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Assure my_channels statistics cannot go negative in server.
1055 Affected files silcd/server.c, silcd/server_util.c.
1057 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1059 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1061 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1063 * Win32 Toolkit changes. Affected files
1064 win32/silc.dsw, win32/libsilc/libsilc.def,
1065 win32/libsilcclient/libsilc.def,
1066 lib/silcutil/silcutil.c, and
1067 lib/sftp/sftp_fs_memory.c.
1069 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Added silc_net_localip to return local host's IP address.
1072 Affected file lib/silcutil/silcnet.[ch].
1074 * If key exchange or rekey protocol is active for a connection
1075 parse all packets syncronously since there might be packets
1076 in packet queue that we are not able to process without first
1077 processing packets before them. Affected file silcd/server,
1078 lib/silcclient/client.c.
1080 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1081 whether library should continue processing the packet.
1082 Affected file lib/silccore/silcpacket.h.
1084 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1085 SilcSFTPMonitorData to SFTP server to monitor various
1086 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

1089 * Added silc_file_size to return file size. Affected file
1090 lib/silcutil/silcutil.[ch].
1092 * Implemented the file transfer support for the client library.
1093 Added preliminary support for simple client to client one-file
1094 transmission. Affected file lib/silcclient/client_ftp.c,
1095 lib/silccilent/client.[ch].
1097 * Added new local command FILE to the Irssi SILC Client.
1098 It is used to perform the file transfer. It has subcommands
1099 SEND, RECEIVE, SHOW and CLOSE. Affected files
1100 irssi/src/silc/core/client_ops.c,
1101 irssi/src/silc/core/silc-server.[ch].
1103 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Relay the SILC_PACKET_FTP in the server. Affected files
1106 silcd/server.c and silcd/packet_receive.c.

1110 * Renamed silc_file_read and silc_file_write to functions
1111 silc_file_readfile and silc_file_writefile. Added function
1112 silc_file_open and silc_file_close. Affected files
1113 lib/silcutil/silcutil.[ch].
1115 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1117 * Resolve the client info when received private message or
1118 channel message for a client which nickname we don't know.
1119 Affected files lib/silcclient/client_prvmsg.c and
1120 lib/silcclient/client_channel.c.
1122 * Do not crash in /KEY if client is not connected. Affected
1123 file irssi/src/silc/core/silc-channels.c.
1125 * Added SilcClientStatus field to the SilcClientEntry in the
1126 lib/silcclient/idlist.h.
1128 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1129 is incomplete and is being resolved, it won't be resolved
1132 Make sure also that USERS command reply does not resolve
1133 twice information. Affected file is
1134 lib/silcclient/command_reply.c.
1136 Make sure that silc_client_get_clients_by_list does not
1137 resolve twice same information.
1139 * Check for valid client->id in the silc_server_free_client_data.
1140 Affected file silcd/server.c.
1142 * Fixed /GETKEY nick@server not to crash if the server entry
1143 is not found. Affected file lib/silcclient/command.c.
1145 * Fixed the silc_server_check_cmode_rights to check the
1146 requested modes correctly. Affected file silcd/command.c.
1148 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1150 * Better checks for non-printable chars in nick added.
1151 Affected file silcd/command.c.
1153 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Call the silc_server_udpate_servers_by_server in the
1156 primary router that comes back online in the backup resuming
1157 protocol. Otherwise it routes packets wrong. Affected file
1158 silcd/server_util.[ch], silcd/server_backup.c.
1160 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1163 lib/silcutil/silcbuffmt.[ch].
1165 * Redefined the SILC packet header to include the padding
1166 length. Affected file lib/silccore/silcpacket.[ch].
1168 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1169 length for maximum padding up to 128 bytes). Affected
1170 file lib/silccore/silcpacket.h.
1172 * Removed all backwards support for old 0.5.x MAC thingies.
1173 The SILC packet header change makes it impossible to be
1174 backwards compatible.
1176 * Send the ENDING packet with timeout in the backup resuming
1177 protocol. This is to assure that all routers has connected
1178 to the primary router. Affected file silcd/server_backup.c.
1180 * Changed the RNG to take the first IV from random data. It
1181 used to take it from zero actually. Changed the RNG also
1182 to use /dev/urandom during session. /dev/random is used
1183 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1185 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Changed the SILC packet header to have the first two bytes
1188 (the packet length) encrypted. Affected files aroung the
1189 code tree, lib/silccore/silcpacket.[ch]. Removed the
1190 SilcPacketCheckDecrypt callback. It is not needed anymore
1191 since the silc_packet_receive_process will determine now
1192 whether the packet is normal or special.
1194 * Implemented the unidirectional MAC keys. Affected files
1195 lib/silcske/silcske.c, silcd/protocol.c and
1196 lib/silcclient/protocol.c.
1198 * Implemented the packet sequence number to the MAC computation.
1199 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1200 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1201 lib/silcclient/protocol.c.
1203 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Allow backup router to announce servers. All servers
1206 announced by backup router are added to the global list
1207 automatically. Update hte server's socket to our primary
1208 router also when backup router announces a server.
1209 Affected file silcd/packet_receive.c.
1211 * Do not update the client->router in the function
1212 silc_server_udpate_clients_by_server if the client is on
1213 global list. We might fail to find any specific server
1214 for locally connected clients and local cell clients. They
1215 should still use the `from' and not `to' as client->router.
1216 This fixes backup router resuming protocol. Affected file
1217 silcd/server_util.c.
1219 * Decrease channel statistics count only if the channel
1220 deletion worked. Affected files are silcd/server.c and
1221 silcd/server_util.c.
1223 * Added silc_server_update_servers_by_server to update origin
1224 of all server entries. Used during backup router protocol.
1225 Affected files silcd/server_util.[ch], silcd/server.c. and
1226 silcd/backup_router.c.
1228 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1229 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1230 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1231 lib/silccrypt/silchmac.c.
1233 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Assure that router cannot reroute the same channel message
1236 to the sender. Affected file silcd/packet_receive.c.
1238 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1240 * Made better checks that the channel message is not sent
1241 to the router it came from. Affected file is
1242 silcd/packet_send.c. Fixed memory leak too.
1244 * Announce informations for incoming router connection, but
1245 only after checking if it is replaced by backup router.
1246 Affected file silcd/packet_receive.c.
1248 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1250 * Fixed the backup resuming protocol to work in multiple
1251 router environment. Affected file silcd/server_backup.c.
1253 * Route packet only to one router in the function
1254 silc_server_packet_send_to_channel. Affected file is
1255 silcd/packet_send.c.
1257 * Fixed silc_server_send_notify_dest to set the broadcast
1258 flag. Fixed the silc_server_send_notify_topic to actually
1259 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1260 Affected file silcd/packet_send.c.
1262 * Changed the SFTP Filesystem interface. Changed the
1263 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1264 the filesystem operation function. The SilcSFTPFilesystem
1265 is now a context that is allocated by all filesystem allocation
1266 functions and it already includes the operations structure
1267 and filesystem specific context. It is given as argument
1268 now to the silc_sftp_server_start. This made the interface
1269 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1270 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1272 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * Changed the backup router adding and getting interfaces
1275 in the server. The router that will be replaced by the
1276 specified backup router is now sent as argument. Affected
1277 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1280 * Added silc_net_addr2bin_ne to return the binary form of
1281 the IP address in network byte order. Affected files
1282 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1284 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Check for existing server ID in silc_server_new_server
1287 and in silc_server_connect_to_router_final and remove the
1288 old entry if it exists. Affected file silcd/packet_receive.c,
1291 * Send the channel message always to only one router, either
1292 in upstream or downstream. Affected file is
1293 silcd/packet_send.c.
1295 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1297 * Wrote the definition of the backup resuming protocol to the
1298 protocol specification.
1300 * Removed one redundant channel key generation from normal
1301 server during joining procedure. Removed one redundant
1302 channel key sending from server to router during joining
1303 procedure. Affected file silcd/command.c.
1305 * Made minor bugfixes to the backup router resuming protocol.
1306 Affected file silcd/server_backup.c, server.c.
1308 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Added --disable-asm configuration option. Affected files
1311 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1314 * Implemented the backup resuming protocol that is used to
1315 resume the primary router position in the cell after the
1316 primary router comes back online. Affected files
1317 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1318 and silcd/server_util.[ch].
1320 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Sleep two (2) seconds after sending QUIT command to server.
1323 Affected file lib/silcclient/command.c.
1325 * Assure that if outgoing data buffer is pending do not force
1326 send any data. Affected file silcd/packet_send.c.
1328 * Assure that if outgoing data buffer is pending do not force
1329 send any data. Affected file lib/silcclient/client.c.
1331 * Implemented the backup router support when the primary router
1332 goes down. The servers and routers can now use the backup
1333 router as new primary router without loosing connectivity.
1335 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1338 in the server to indicate disabled entry. All data read
1339 from the connection will be ignored and no data is sent
1340 for entry that is disabled. Affected files are
1341 silcd/idlist.h, silcd/server.c.
1343 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * Created SFTP client and server test programs in the
1346 lib/silcsftp/tests directory.
1348 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Implemented memory filesystem (virtual filesystem) for
1351 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1354 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1356 * Implemented the SFTP (SSH File Transfer Protocol) to the
1357 lib/silcsftp. It includes SFTP client and SFTP server
1360 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1362 * Moved lib/silccore/silcprotocol.[ch] to the
1363 lib/silcutil library.
1365 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1366 take variable argument list pointer as argument. Affected
1367 file lib/silcutil/silcbuffmt.[ch].
1369 * Added silc_buffer_set function that is used to set data
1370 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1371 Affected file lib/silcutil/silcbuffer.h.
1373 * Changed various routines in the core library to use the new
1374 silc_buffer_set instead of allocating new buffer only for
1377 * Added 64-bit value formatting and unformatting support to the
1378 silc_buffer_[un]format routines. Affected file is
1379 lib/silcutil/silcbuffmt.[ch].
1381 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1382 to includes/bitmove.h.
1384 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Fixed channel user mode saving in client library. Affected
1387 file lib/silcclient/command[_reply].c.
1389 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1391 * Defined the file transfer to the SILC Protocol. Added
1392 new packet type SILC_PACKET_FTP and defined File Transfer
1393 Payload. The mandatory file transfer protocol is SFTP
1394 (SSH File Transfer Protocol). Affected file in addition
1395 of the internet draft is lib/silccore/silcpacket.h.
1397 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1398 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1399 is used as part of backup router protocol when the primary
1400 router of the cell is back online and wishes to resume
1401 the position as primary router.
1403 * Redefined the MAC generation keys in the protocol. The
1404 same key is not used anymore in both direction. Both
1405 direction will now use different keys for sending and
1406 receiving. This fixes a potential security flaw. This
1407 change causes incompatibilities in the protocol.
1409 * Redefined also the MAC computation from the packet.
1410 An packet sequence number is now added to the MAC
1411 computation. This prevents possible replay attacks against
1412 the protocol. This change too causes incompatibilities
1415 Added `sequence' field to the SilcPacketContext to hold
1416 the current sequence number for the packet.
1418 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1420 * Added `created' field to the SilcIDListData in the file
1421 silcd/idlist.h to indicate the time when the entry was
1424 * Added `created' field to the SilcChannelEntry too. Affected
1425 file silcd/idlist.h.
1427 * Added `creation_time' aguments to all the announcement functions
1428 in the server. If it is provided then only the entries that
1429 was created after the provided time frame are actually
1430 announced. Affected file silcd/server.[ch].
1432 * The protocol says that the Channel ID's IP address must be
1433 based on the router's IP address. Added check for this in
1434 the silc_server_new_channel when processing incoming New Channel
1435 Payload. Affected file silcd/packet_receive.c.
1437 * Print out the correct version with --version in SILC client.
1438 Affected file irssi/src/silc/core/silc-core.c.
1440 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Fixed WHOWAS command to check for completnes of the client
1443 entry always, not just when the command is coming from client.
1444 Affected file silcd/command.c.
1446 * Added new function silc_server_packet_queue_purge to purge the
1447 outgoing data queue to the network. After the function returns
1448 it is guaranteed that the outgoing packet queue is empty.
1449 Affected file silcd/packet_send.[ch].
1451 * Purge the outgoing packet queue in the rekey protocol's final
1452 callback to assure that all rekey packets go to the network
1453 before quitting the protocol. Affected file silcd/server.c.
1455 * Added silc_client_packet_queue_parse as similar function as
1456 in server to the client library. The affected file is
1457 lib/silcclient/client.c.
1459 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Splitted silcd/server.c and created silcd/server_util.[ch]
1462 for utility functions.
1464 * Added new socket flag SILC_SF_DISABLED to indicate that the
1465 connection is open but nothing can be sent to or received from
1466 the connection. Affected file lib/silcutil/silsockconn.[ch].
1467 The checking for disabled socket is checked in the low level
1468 silc_socket_write and silc_socket_read functions.
1470 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Allow only nicknames and channel names that fits into the
1473 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1475 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * When processing JOIN command reply in server check that if
1478 the channel exists in our global list we'll move it the local
1479 list. Affected file silcd/command_reply.c.
1481 * Fixed the check whether client is joined on the channel already
1482 in JOIN command. Affected file lib/silcclient/command.c.
1484 * Fixed the JOIN command reply to check whether the channel
1485 already exists. Affected file lib/silcclient/command_reply.c.
1487 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Added silc_ske_status_string to map the SKE error numbers
1490 to readable strings. The affected files are
1491 lib/silcske/silcske[_status].[ch].
1493 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1495 * Do not show the private channels on the WHOIS channel list
1496 as it is not allowed by the protocol. The affected file is
1499 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Assure that the packet length digged from the actual packet
1502 is something sensible in the silc_packet_decrypt_rest_special
1503 in lib/silccrypt/silcpacket.c.
1505 * Free and NULL the allocated pointer in silc_hmac_alloc if
1506 the HMAC allocation fails. The affected file is
1507 lib/silccrypt/silchmac.c.
1509 * Print the selected security properties to the log files in
1510 the server. Affected file silcd/protocol.c.
1512 * Add SKE's reference counter even if calling the completion
1513 callback manually. Otherwise it goes negative, although it
1514 does not cause any problems. The affected file is
1515 lib/silcske/silcske.c.
1517 * Remove the client entry with short timeout after giving the
1518 KILL command. Affected file lib/silcclient/command.c.
1520 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1521 case all found clients are already disconnected (WHOWAS would
1522 found them) in the server. Affected file silcd/command.c.
1524 * Update the last_receive (time of last data received) to be
1525 updated only when received private or channel message so that
1526 the idle time showed in WHOIS makes more sense.
1528 * Added boolean field `valid' in to the SilcClientEntry in the
1529 client library to indicate whether the entry is valid or not.
1530 This fixes the nickname change bug on channel when changing
1531 the nickname to be same than the old (like nick to Nick) the
1532 nickname formatter doesn't set the new nick anymore to Nick@host.
1533 Affected file lib/silcclient/idlist.[ch].
1535 * Now actually fixed the nickname changing on disconnection.
1536 Added new function silc_change_nick to the Irssi SILC Client.
1537 Affected file irssi/src/silc/core/client_ops.c,
1538 irssi/src/silc/core/silc-nicklist.[ch].
1540 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1542 * Check that the public key exists in the GETKEY command before
1543 trying to encode it. Affected file silcd/command.c.
1545 * Print some notifications on received public keys with GETKEY
1546 command in the Irssi SILC Client. Affected files are
1547 irssi/src/fe-common/silc/module-formats.[ch],
1548 irssi/src/silc/core/client_ops.c.
1550 * Use IDENTIFY command to resolve the server information in the
1551 GETKEY command instead of INFO command. Affected file
1552 lib/silcclient/command.c.
1554 * All command reply functions in the client library now calls
1555 the pending command reply callbacks even if an error has
1556 occurred. The server has done this a long time and now it was
1557 time to move the client library to this as well. Now all
1558 errors can be delivered back to the pending command reply
1559 callbacks if necessary. Affected files are
1560 lib/silcclient/command[_reply].[ch].
1562 * Change the nickname on disconnection back to the username
1563 because in reconnect the server will enforce it to it anyway.
1564 Affected file irssi/src/silc/core/silc-servers.c.
1566 * Fixed a config file parsing bug in the Irssi SILC client.
1567 Affected file irssi/src/silc/core/clientconfig.c.
1569 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * When printing the channel mode on JOIN, verify that the
1572 channel key and channel's HMAC are valid. Affected file
1573 irssi/src/silc/core/client_ops.c.
1575 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1578 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1579 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1581 * Removed channel key rekey task deleting from the function
1582 silc_server_save_channel_key. Affected file silcd/server.c.
1583 Added explicit timeout task context instead that is used to
1584 delete the task if we are registering a new task before the
1585 new task has elapsed.
1587 * When channel key rekey occurs the client library now saves
1588 the old channel key for a short period of time (10 seconds) and
1589 is able to use it in case some is still sending channel
1590 messages encrypted with the old key after the rekey. Affected
1591 file lib/silcclient/[idlist.h|client_channel.c].
1593 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Added check to the silc_server_new_id_real to not accept
1596 new ID if it is the sender's own ID. Affected file is
1597 silcd/packet_receive.c.
1599 * Assure that we do not announce ourself or the one we've
1600 sending our announcements when we're router and are announcing
1601 servers to our primary router. Affected file silcd/server.c.
1603 * Fixed silc_server_command_identify_check_client to assemble
1604 correct WHOIS packet. It send corrupted WHOIS packet and
1605 caused problem with router to router connections. Affected
1606 file silcd/command.c.
1608 Fixed also silc_server_command_whois_check the same way
1609 as for the IDENTIFY command.
1611 * Added new SilcIDListStatus to the server in the SilcIDListData
1612 structure. The status now includes the current status of
1613 the entry (like registered, resolved etc.). Affected file
1614 silcd/idlist.[ch]. Defined a bunch of different status types
1615 as well. This replaced the old boolean registered field as well.
1617 Added resolve_cmd_ident field to the SilcClientEntry structure
1618 too so that if the entry is for example being resolved so
1619 another command may attach to the same pending command reply
1620 without requiring to resolve the same entry again. This concept
1621 should optimize the WHOIS and the IDENTIFY resolving under
1622 heavy load by taking away unnecessary resolving for entries
1623 that are being resolved already.
1625 Added support for adding multiple pending commands for one
1626 command idenfier. Affected file silcd/command[_reply].[ch].
1628 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1629 before deleting the data. Otherwise the hash table will have
1630 freed data in comparison functions. Affected file is
1631 silcd/command_reply.c.
1633 * Fixed silc_idlist_replace_client_id to add the new entry to
1634 the cache with NULL nickname. Otherwise there will be invalid
1635 memory as the nickname after the nickname is freed. Affected
1636 file silcd/packet_receive.c.
1638 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1639 saved into wrong slots because the previous number of entries
1640 was not taken into account. Affected file silcd/idlist.c.
1641 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1643 * If we are router and we receive JOIN notify to a channel that
1644 does not have any users then notified client is marked as the
1645 channel founder, as it is it. The affected file is
1646 silcd/packet_receive.c
1648 * Added to the extended hash table API's table_del_*ext functions
1649 the destructor as argument too, so that the caller can decide
1650 which destructor to use or whether to use destructor at all.
1651 Affected file lib/silcutil/silchashtable.[ch].
1653 * Fixed ID Cache purging. It actually deleted the entries from
1654 the hash table after the data was freed. The hash table ended
1655 up comparing freed memory. The affected file is
1656 lib/silccore/silcidcache.c.
1658 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1660 * Fixed Irssi SILC client's KILL command's HELP syntax.
1662 * The USERS command now resolves the detailed user information
1663 if the userinfo field is missing. Affected file is
1664 lib/silcclient/command_reply.c.
1666 * Do not print error in silc_file_read if the read file does
1667 not exist. Just silently return NULL. Affected file is
1668 lib/silcutil/silcutil.c.
1670 * Fixed the silc_log_output to not wine about NULL filename
1671 and to not create some bogus " " filename. Affected file is
1672 lib/silcutil/silclog.c.
1674 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Fixed various printing bugs on the user interface in the
1677 Irssi SILC Client. Minor changes that were forgotten from
1680 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Fixed the configure.in.pre and the compilation and distribution
1683 environment to support the new autoconf 2.52. That version is
1684 now required to compile the CVS trunk.
1686 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1689 to generally parse user@fqdn format strings. Affected file
1690 lib/silcutil/silcutil.c.
1692 * Added nickname_format and nickname_force_format fields to the
1693 SilcClientParams structure. The first one defines the format
1694 for the nicknames that the library will enforce if the receives
1695 multiple same nicknames. The second one is boolean value and
1696 can be used to force the library to always enforce the format
1697 to the nicknames regardles whether there are multiple nicknames
1698 or not. This configurable formatting was employed to flexibly
1699 support accessing multiple nicknames from the user interface.
1700 The userinterface can now set the nicknames to what ever format
1701 they prefer. Affected file lib/silcclient/silcapi.h.
1703 Added function silc_client_nickname_format to the file
1704 lib/silcclient/idlist.c. It performs the nickname formatting.
1706 Added new field `hostname´ to the SilcClientEntry context.
1707 It holds the hostname of the client. Affected file is
1708 lib/silcclient/idlist.h.
1710 * Irssi SILC Client sets the nicknames in nick@hostn format.
1711 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1712 irssi/src/silc/core/silc-core.c.
1714 The WHOIS printing now also shows both the real nickname and
1715 the formatted nickname so that user knows how to access the
1716 user if there are multiple same nicknames cached. Affected
1717 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1718 printing formatting too to take the hostname now as a separate
1719 argument. The Affected file is
1720 irssi/src/fe-common/silc/modules-formats.[ch].
1722 * Changed the silc_client_get_clients_local to accept the formatted
1723 nickname as argument. It accepts the real nickname too but the
1724 formatted nickname can be used to find the true entry from
1725 multiple entries. Affected file lib/silcclient/silcapi.h and
1726 lib/silcclient/idlist.c.
1728 * Added nickname_format_parse field to the SilcClientParams.
1729 It is a callback function provided by the application to parse
1730 the nickname out of the formatted nickname string. The library
1731 calls it to get the nickname from the formatted string. Since
1732 the application generally knows better the format of the nickname
1733 string it parses it instead of the library, even though library
1734 encodes the formatted string. If the callback function is not
1735 provided then the library will use the string as is. The
1736 affected file is lib/silcclient/silcapi.h.
1738 * All the nickname strings passed to the client library in
1739 commands are now expected to be formatted nickname strings.
1740 If the command does not support the formatted nickname string
1741 it will assume that the sent string is the actual nickname.
1742 Affected file lib/silcclient/command.c.
1744 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1746 * Added public key authentication support to OPER and SILCOPER
1747 commands in the client library. Affected file is
1748 lib/silcclient/command.c.
1750 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1752 * Changed the get_auth_methdod client operation to be asynchronous.
1753 It can be async if the application resolves the authentication
1754 method from the server during the negotiation. Added new
1755 SilcGetAuthMeth completion callback that the application will
1756 call after resolving the authentication method.
1758 Added function silc_client_request_authentication_method that
1759 the application can use to resolve the authentication method
1760 from the server. Added also SilcConnectionAuthRequest callback
1761 that the library will call after the server has replied. The
1762 application can call this function if it does not know the
1763 current authentication method.
1765 Affected files are lib/silcclient/client.c and
1766 lib/silcclient/silcapi.h.
1768 * The Irssi SILC client now automatically resolves the authentication
1769 method incase any configuration information is not present (and
1770 currently there never is). The affected file is
1771 irssi/src/silc/core/client_ops.c.
1773 * Fixed public key authentication from the client library.
1774 Affected file lib/silcclient/protocol.c. Changed also the
1775 protocol specification about the public key authentication in
1776 the connection authentication protocol. The actual data to be
1777 signed is now computed with a hash function before signing.
1779 * Fixed the public key authentication from the server as well.
1780 Affected file silcd/protocol.c.
1782 * Removed the mlock()'s from the memory allocation routines.
1783 Affected file lib/silcutil/silcmemory.c. The ./configure does
1784 not check anymore for the mlock(). Affected file is
1787 * Fixed USERS command in server to allow the execution of the
1788 command for private and secret channels if the client sending
1789 the command is on the channel. Affected file silcd/command.c.
1791 * Fixed silc_client_get_clients_local to return the clients
1792 count correctly. It could return wrong value. Affected file
1793 lib/silcclient/idlist.c.
1795 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1798 types. The assembler optimizations seemed not to like 64-bit
1799 data types. The assmebler optimizations thus are now enabled
1800 also for BSD systems as opposed to only enable them for Linux.
1802 * Do not check for threads at all on BSD systems. Affected
1803 file configure.in.pre.
1805 * Removed -n and -h options from the Irssi SILC Client since
1806 they are not used in silc.
1808 * Fixed the prime generation to assure that the first digit
1809 of the generated random number is not zero since our conversion
1810 routines does not like number strings that starts with zero
1811 digit. If zero digit is seen the random number is regenerated.
1812 This caused some corrupted RSA keys when the zero first digit
1813 was met. Affected file lib/silcmath/silcprimegen.c.
1815 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1817 * Fixed WIN32 configuration in the ./configure script.
1818 Fixed to include xti.h on environments that has it.
1819 Patches by Carsten Ilchmann and andrew.
1821 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Changed the silc_id_create_client_id to be collision
1824 resistant. It is now assured that there cannot be created
1825 two same client ID's. I suspect that some weird bugs in
1826 the server were actually caused by duplicate Client IDs.
1827 Affected file silcd/serverid.[ch]. A router receiving
1828 new ID now also assures and informs the sending server
1829 if the ID caused collision.
1831 * Changed the silc_id_create_channel_id to also assure that
1832 there are no collisions.
1834 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Statement about ignoring the Mutual Authentication flag when
1837 performing rekey with PFS was a bit misleading. It is ignored
1838 if it was set in the initial negotiation, it cannot be even
1839 set in the rekey. Fixed in the ke-auth draft. Started the
1840 new versions of the protocol drafts in the doc/.
1842 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1844 * Fixed a bug in silc_client_command_identify_save when saving
1845 new channel information. The channel name was no duplicated
1846 and caused crash on exit. Affected file is
1847 lib/silcclient/command_reply.c.
1849 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Fixed the getkey command handling in the server. Send just
1852 empty OK reply to the sender if the key could not be fetched
1853 (but everything else was ok, like the key just was not available).
1854 Changed the public key parameter to optional in the protocol
1855 specs so that empty OK reply can be sent. Affected file
1858 Added a message to Irssi SILC client to tell to user if the
1859 server did not return a public key.
1861 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Fixed a channel key regeneration bug. It registered new
1864 timeout tasks exponentially until all system resources were
1865 used. Affected file silcd/server.c.
1867 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Added the SILC Document generator to the scripts/silcdoc.
1870 It can be used to generate the Toolkit Reference Manual out
1871 of the source tree. Internally it will also use the RoboDoc
1872 generator now imported in util/robodoc.
1874 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Added couple of return's in rekey protocol if error orccurred
1877 during the protocol. The execution must be terminated.
1878 Affected file silcd/protocol.c. Also, terminate the protocol
1879 always with timeout.
1881 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * The client's Client ID was created initally from the wrong
1884 nickname (it could have been in format nick@host) in the
1885 silc_server_new_client. Affected file silcd/packet_receive.c
1887 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1889 * Added some SILC_LOG_ERROR's to various error conditions
1890 if client could not be added to ID cache. Affected files
1891 silcd/packet_receive.c and silcd/server.c.
1893 * When client's sock->user_data is freed, NULL also the
1894 client->router and client->connection pointers. Added check
1895 for these pointers being NULL to various places around the
1896 code. Affected file silcd/server.c.
1898 * Added client->data.registered == TRUE checks to various
1899 places around the code to assure that unregistered client's
1900 are not handled when it is not allowed. Affected file
1903 * Added `bool registered' fields to all
1904 silc_idlist_[server|client]_get_* routines to indicate whether
1905 the fetched client needs to be registered or not. Affected
1906 file silcd/idlist.[ch].
1908 * Add your own entry as registered to the ID cache in the
1909 server. Affected file server.c.
1911 * Fixed a bug in silc_server_new_server. The SilcServer was
1912 set as the new server's context instead of SilcServerEntry.
1913 This naturally caused some weird bugs.
1915 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Do not delete the channel rekey task when adding it
1918 for in silc_server_create_channel_key.
1920 * Changed the silc_server_create_channel_key to return
1921 TRUE or FALSE to indicate the success of the channel key
1924 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1926 * Fixed MSVC++ project files and added missing files to
1927 Makefiles under win32/.
1929 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Do not add TCP_NODELAY flag if the operating system
1932 does not have it defined. Affected files are
1933 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1935 * Fixed buffer overflow from Irssi SILC Client. Affected
1936 file irssi/src/fe-common/core/themes.c.
1938 * Fixed double free in client library in the file
1939 lib/silcclient/client.c when disconnecting from server.
1941 * Applied double free patch from cras to Irssi SILC client.
1942 Affected files irssi/src/core/[modules/expandos].c
1944 * Fixed the disconnection handling to Irssi SILC Client.
1945 The application must call silc_client_close_connection
1946 in ops->connect client operation in case of failure of
1947 the connection. Affected file is
1948 irssi/src/silc/core/client_ops.c.
1950 * Do not set sock->protocol to NULL in the function
1951 silc_client_close_connection after executing the protocol's
1952 final callback since the sock might not be valid anymore.
1953 Affected file lib/silcclient/client.c.
1955 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1957 * Do not enable SILC_THREADS if the linking with libpthread
1958 did not happen. Affected file configure.in.pre.
1960 * Added notion to protocol specification that server must
1961 verify the sent authentication payload with CMODE when
1962 setting the channel founder key. Implemented it to the
1963 server. Affected file silcd/command.c.
1965 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * Added _EXTRA_DIST SILC distribution variable to the
1968 distributions file. It is used to conditionally add extra
1969 files or directories to the specific distribution. Affected
1970 files ./prepare, Makefile.am.pre and distributions.
1972 Removed the `_' from the start of the distribution names.
1975 * Added README.WIN32 for instructions to compile the Toolkit
1978 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Fixed a double free in disconnection in the server. Affected
1981 file is silcd/server.c.
1983 * Fixed the lib/silcske/groups.c to work now also with GMP
1984 MP library. The string conversion did not work when using
1985 specific base and the base is indicated in the string as well.
1987 * Created win32/ directory which now includes MSVC++ specific
1988 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1989 It will appear only in the toolkit distribution
1991 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Changed the key material distribution function in case when
1994 the hash output is too short. The data is now concatenated
1995 a bit differently than it used to. Made the change to the
1996 SKE protocol specification.
1998 * Added better GMP detection to configure.in.pre. A patch
2001 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * Fixed a minor bug in SKE that might cause some problem on
2004 some platforms. Affected file lib/silcske/silcske.c.
2006 * Added the cookie checking for initiator in the SKE. It checks
2007 that the responder returns the sent cookie unmodified. The
2008 affected file is lib/silcske/silcske.c. Added new SKE
2009 error type INVALID_COOKIE that can be sent during the
2010 negotiation. Fixed some memory leaks as well.
2012 * Added the "invalid cookie" error message to Irssi SILC client's
2015 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Added `task_max' field to the SilcClientParams to indicate
2018 the maximum tasks the scheduler can handle. If set to zero,
2019 default values are used. Affected file lib/silcclient/silcapi.h.
2021 * Fixed memory leaks in silc_client_close_connection. Affected
2022 file lib/silcclient/client.c.
2024 * Added silc_client_del_client_entry to client library to free
2025 all memory of given client entry. Affected file is
2026 lib/silcclient/idlist.[ch].
2028 * Added new functions silc_client_del_channel and
2029 silc_client_del_server to delete channel and server entries.
2030 Affected file lib/silcclient/[silcapi.h/idlist.c].
2032 * Removed silc_client_del_client_by_id from silcapi.h.
2034 * Fixed the INFO command to return the server's own info
2035 correctly when querying by Server ID. Affected file is
2038 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2040 * Removed the non-blocking settings in WIN32 code in the
2041 silc_sock_[read/write] and added SleepEx instead. Affected
2042 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2043 of input data is now checked with FIONREAD and ioctlsocket.
2045 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Call silc_schedule_task_del_by_context in the
2048 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2049 Affected file lib/silccore/silcprotocol.c.
2051 * Call silc_protocol_cancel for active protocols in the
2052 silc_server_close_connection if the funtion
2053 silc_server_free_sock_user_data has not been called.
2054 Affected file silcd/server.c.
2056 * Generic tasks cannot be deleted using the del_by_fd
2057 task deleting function since generic tasks does not match
2058 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2060 * Added a notion to SILCOPER help file that the SILCOPER works
2061 only on router server, not on normal server.
2063 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2065 * Added for WIN32 support for the new scheduler as well.
2066 Affected file lib/silcutil/win32/silcwin32schedule.c.
2068 * Fixed the SHA1 implementation to work on various platforms.
2070 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2073 API. It is part of the scheduler now. Everything else is
2074 as previously but some functions has changed their names.
2075 Checkout the lib/silcutil/silcschedule.h for the interface.
2076 Updated all applications to use the new interface. Affected
2077 files are lib/silcutil/silcschedule.[ch].
2079 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Found a bug in the SKE implementation. The HASH value,
2082 specified by the protocol, was not computed correctly. The
2083 public key of the responder was not added to the computation
2084 even though it is mandatory. Affected file lib/silcske/silcske.c.
2085 This unfortunately causes incompatibilities with older
2086 clients and servers.
2088 * Added WIN32 specific network init and uninit functions:
2089 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2090 the Winsock2. Affected file lib/silcutil/silcnet.h and
2091 lib/silcutil/win32/silcwin32net.c.
2093 * Set the socket always to nonblocking mode on WIN32 after
2094 reading data or writing data. Affected file is
2095 lib/silcutil/win32/silcwin32sockconn.c.
2097 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed various compilation problems under WIN32. Affected
2100 files lib/silcutil/win32/silcwin32thread.c and
2101 lib/silcutil/win32/silcwin32schedule.c.
2103 * Removed all _internal.h #includes from public header
2104 files. Internal headers must never be included from
2107 Removed also the lib/silcske/payload_internal.h file.
2109 * All include files that may be needed (public and some others
2110 included by the public headers) by application developers are
2111 now copied to the ./includes directory. It does not copy any
2112 internal headers. Affected file Makefile.defines.pre and all
2113 Makefile.am's under lib/ and subdirs.
2115 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2117 * Do not change the ~/.silc directory's permissions automatically.
2118 Affected file irssi/src/silc/core/clientutil.c.
2120 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * Do not cancel the protocol in silc_server_close_connection
2123 it might cause recursion. Now cancelled in the function
2124 silc_server_free_sock_user_data. Affected file silcd/server.c.
2126 * Fixed the silc_server_remove_clients_by_server to regenerate
2127 the channel keys correctly finally. Added also new function
2128 silc_server_remove_clients_channels to actually do it.
2129 Affected file silcd/server.c.
2131 * Fixed the silc_server_new_channel to not crash by giving
2132 wrong router to the new channel. Affected file is
2133 silcd/packet_receive.c.
2135 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2138 which is given as argument to the silc_client_alloc now.
2139 It can be used to configure the client and set various parameters
2140 that affect the function of the client.
2142 * The USERS command in server did not check whether the channel
2143 is private or secret. Affected file silcd/command.c.
2145 * Added new argument to the USERS command in protocol specification.
2146 The USERS command now can take the channel name as argument
2147 as well. Added support for this in client and server and
2148 updated the protocol specs.
2150 * Completed the GETKEY command in client. It can be now used
2151 to fetch also servers public key not only some clients.
2152 Affected files lib/silcclient/command[_reply].c.
2154 * Added silc_client_get_server to return server entry by the
2155 server name. Affected files lib/silcclient/silcapi.h and
2158 * Redefined the IDENTIFY command in protocol specification to be
2159 more generic. It now can be used to query information about
2160 any entity in the SILC Network, including clients, servers and
2161 channels. The query may be based either the entity's name
2162 or the ID. Added support for this in both client and server.
2164 Affected files silcd/command.c and lib/silcclient/command.c
2165 and command_reply.c.
2167 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2168 the _from_client and _from_server functions. Affected file
2171 * Added silc_client_get_channel_by_id_resolve to the file
2172 lib/silcclient/silcapi.h to resolve channel information by
2173 its ID. Added also silc_client_get_channel_by_id that
2174 does not resolve it from the server.
2176 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Added SilcServerEntry context into the client library
2179 to represent one server. The INFO command now allocates
2180 these to save the resolved server info. For now on the
2181 client library will also keep information about servers,
2182 connected and resolved with INFO.
2184 The INFO command now allocates the SilcServerEntry context
2185 and saves the server info there. The COMMAND_REPLY in
2186 the INFO now returns the parameters to application in
2187 same order as defined in the protocol specification.
2189 The entries are cached in the client->server_cache.
2191 * The INFO command is now issued after received the Client ID
2192 from the server. Affected file lib/silcclient/client.c.
2194 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2195 to the application as the mode changer might be server.
2196 It is guaranteed that NULL is not returned anymore to the
2197 application. Affected file lib/silcclient/client_notify.c.
2199 The ID Type is now also passed to the application so that
2200 it can check whether the returned entry is SilcClientEntry
2203 Added new function silc_client_get_server_by_id to return
2204 the server entry by ID. Affected files are the
2205 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2207 * Do not create the channel in the Irssi SILC Client when issuing
2208 the JOIN command but when received the sucessful JOIN command
2209 reply. Otherwise the channel might get created even though we
2210 could not join it. The Affected file is
2211 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2213 * Fixed a channel joining bug in router. The router must also
2214 check the channel modes, invite and ban lists etc. when serving
2215 the JOIN command sent by normal server. Affected file is
2216 silcd/command.c. The router now resolves the client's
2217 information from the server who sent the JOIN command if it
2218 does not know it, and processes the JOIN command only after
2221 * Changed the SilcCommandCb to take new argument; void *context2.
2222 Affected file lib/silccore/silccommand.h
2224 The second argument in the command callbacks in the server now
2225 includes the SilcServerCommandReplyContext if the command was
2226 called as pending command callback from the command reply.
2227 Otherwise it is NULL. When called as pending the status of the
2228 command reply will be checked and if it was erronous the
2229 error will be sent to the original sender of the command.
2230 This way the client always receives the error messages even
2231 though the server was actually the one who received the error
2232 when it resent the command to router, for example. Affected
2233 files silcd/command[_reply].[ch].
2235 * Fixed sending WHOWAS command's error message to client if
2236 the requested client could not be found. It was missing.
2239 * Changed the CMODE and CUMODE commands reply arguments in the
2240 protocol specification. The Channel ID is now sent in both
2241 of the commands to identify the channel. Implemented this
2242 new feature to the client and server. Affected files
2243 lib/silcclient/command_reply.c and silcd/command.c.
2245 * Made better checks for invite and ban lists in the JOIN
2246 command in server. Affected file silcd/command.c.
2248 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * The server now performs the incoming host IP/DNS lookup
2251 using the silc_socket_host_lookup and thus does not block
2252 the server anymore. Affected file silcd/server.c.
2254 * Completed the multi-thread support for SILC Scheduler in
2255 the lib/silcutil/silcschedule.c.
2257 * Fixed the configure.in.pre to detect the pthread correctly
2260 * Fixed a deadlock in silc_task_queue_wakeup in the file
2261 lib/silcutil/silctask.c.
2263 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2265 * Added new function silc_schedule_wakeup that is used in
2266 multi-threaded environment to wakeup the main thread's
2267 schduler. It needs to be used when a thread adds a new task
2268 or removes a task from task queues. After waking up, the
2269 scheduler will detect the task queue changes. If threads
2270 support is not compiled in this function has no effect.
2271 Implemented the wakeup mechanism to both Unix and WIN32
2272 systems. Affected files are lib/silcutil/silcschedule.[ch],
2273 lib/silcutil/unix/silcunixschedule.c and the
2274 lib/silcutil/win32/silcwin32schedule.c.
2276 * Added new function silc_task_queue_wakeup to wakeup the
2277 scheduler by the specified task queue. Affected file
2278 lib/silcutil/silctask.[ch].
2280 * The silc_socket_host_lookup_start now wakes up the scheduler
2281 after adding the timeout task. Affected file is
2282 lib/silcutil/silcsockconn.c.
2284 * The silc_socket_host_lookup is synchronous now if the threads
2285 support is not compiled in. However, the callback is still
2286 called asyncronously through the scheduler, anyway. Affected
2287 file lib/silcutil/silcsockconn.c.
2289 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2291 * Added new function silc_socket_host_lookup to perform
2292 asynchronous IP and FQDN lookups for the socket connection.
2293 Affected files lib/silcutil/silcsockconn.[ch].
2295 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2298 that may or may not compile the mutex support in.
2300 Changed the silc_mutex_alloc interface. It allocates the
2301 mutex now to the sent pointer and returns TRUE or FALSE.
2303 Affected file lib/silcutil/silcmutex.h.
2305 * Wrote the SILC Task Queue interface to support multi-threads.
2306 Affected file lib/silcutil/silctask.[ch].
2308 * Wrote the SILC Scheduler to support multi-threads. Affected
2309 file lib/silcutil/silcschedule.c.
2311 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2314 in lib/silcutil/win32/.
2316 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Defined SILC Mutex API and SILC Thread API and implemented
2319 them for Unix. Affected files are
2320 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2321 lib/silcutil/unix/silcunixmutex.c and
2322 lib/silcutil/unix/silcunixthread.c.
2324 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Fixed the silc_server_remove_clients_by_server's channel
2327 key re-generation. The hash table handling was incorrect
2328 and would not work with many channels. Affected file is
2331 * Fixed some memory leaks around the server code.
2333 * Rewrote the silc_server_get_users_on_channel to support IPv6
2334 based Client ID's. Affected file silcd/server.c.
2336 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2337 specification. However, a separate document must be written
2338 to define the detailed signing procedure and the payload
2339 associated with the flag. Defined the flag to the
2340 lib/silccore/silcchannel.h as well.
2342 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Changed the dynamic tables to static size tables in the
2345 lib/silccrypt/silchmac.c.
2347 * Removed GCC dependencies from the code. A patch by cras.
2349 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Do not show the error "Error receiving packet bla bla"
2352 in server if it really was not an error (-2 means that reading
2353 is pending). Affected file silcd/server.c.
2355 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2357 * Fixed a possible crash in silc_server_remove_clients_by_server
2358 in silcd/server.c. Fixed there also some memory leaks.
2360 * Fixed the silc_idlist_replace_client_id. It could replace
2361 wrong key in the hash table. Affected file silcd/idlist.c.
2363 * Do not check whether there are global users on the channel
2364 if the channel->global_users is FALSE. Affected functions
2365 silc_server_remove_from_one_channel and
2366 silc_server_remove_from_channels in silcd/server.c. Also,
2367 do not check if the removed client is local as we can be
2368 sure that global client was not removed from the channel
2369 and checking for global users is not needed.
2371 * The silc_server_remove_clients_by_server now re-generates
2372 the channel keys correctly for those channels that had
2373 clients removed from them. Affected file silcd/server.c.
2375 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2377 * Found the reason of random crashes in the server. We weren't
2378 ignoring the SIGPIPE signal (which can be sent in write())
2379 and it crashed the server. Affected file silcd/silcd.c.
2381 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Assure that sock->user_data is not NULL in the function
2384 silc_server_packet_send in silcd/packet_send.c.
2386 * Disconnect the remote connection if it could not be added
2387 to any ID lists in the server. The affected file is
2390 * Check in silc_server_packet_send[_real/dest] that the
2391 socket is not disconnecting and ignore the data if it is.
2392 Affected file silcd/packet_send.c.
2394 * Define inline to __inline on native WIN32 compilation.
2395 Affected file includes/silcwin32.h.
2397 * Added some explicit type casts for inline code since MSVC
2398 require them. Affected files lib/silcutil/silcbuffer.h,
2399 lib/trq/silcdlist.h and lib/trq/silclist.h.
2401 * Print warning in log files from now on if the packet
2402 decryption fails. Affected file silcd/server.c.
2404 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2406 * Changed the `say' client operation's interface to accept
2407 new `type' argument to indicate the type of the message sent
2408 by the library. The application may filter the library's
2409 messages according the type. The affected file is the
2410 lib/silcclient/silcapi.h.
2412 * Added two new functions to lib/silcclient/silcapi.h:
2413 silc_client_del_client and silc_client_del_client_by_id.
2414 Affected file lib/silcclient/idlist.c.
2416 * Moved the clientincludes.h from includes/ to silc/ and
2417 serverincludes.h from includes/ to silcd/.
2419 * The modes for the CMODE and CUMODE are now passed as
2420 uint32 for application with COMMAND_REPLY. The affected
2421 file is lib/silcclient/command_reply.c.
2423 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * /WHOIS without arguments shows client's own information.
2426 Affected file lib/silcclient/command.c.
2428 * Changed PING to not accept any arguments. The specs
2429 says that client can ping only the connected server so
2430 requiring an argument is not needed. Affected file is
2431 lib/silcclient/command.c.
2433 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Fixed a fatal bug in private message sending and reception
2436 encryption and decryption when using private message keys.
2437 The implementation was incorrect and did not follow the
2438 specification. It causd that some of the message were
2439 lost since it did not use the sending and receiving keys
2440 as the protocol suggests. This has been fixed and will cause
2441 incompatibilities with older clients when sending private
2442 message encrypted with private message keys. Affected files
2443 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2444 and various other in Irssi SILC Client.
2446 Added `responder' boolean argument to the functions
2447 silc_client_add_private_message_key[_ske] to indicate when
2448 the key is added as responder or initiator of the key
2451 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * Removed the silc_ske_check_version function and created
2454 a SilcSKECheckVersion callback. Added also a function
2455 silc_ske_set_callbacks that is now used to set all SKE
2456 callbacks. The callback functions are not given to
2457 the SKE functions anymore, but this function is used to
2460 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2462 * Added `silc_version' argument to the silc_client_alloc
2463 to define the version of the application for the library.
2464 The library will use the version string to compare it
2465 against the remote host's (usually a server) version
2466 string. Affected file lib/silcclient/silcapi.h
2468 * Added the KE protocol context to Key Agreement context
2469 in client library so that we can abort the SKE if it
2470 is in process when we get timeout. Affected file is
2471 lib/silcclient/client_keyagr.c.
2473 * Do not resolve the client ID forever if it returns in the
2474 first time that such client does not exist. This was done
2475 for example with private message. Affected file is
2476 lib/silcclient/client_prvmsg.c.
2478 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Do not add regex.h for WIN32. The affected file
2481 includes/silcincludes.h.
2483 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2484 not work yet 100%. It generates the DLL's automatically
2485 when compiling with --with-win32 under cygwin.
2487 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * lib/contrib/regex.c is not compiled on WIN32.
2491 * Added silc_net_get_socket_opt function to the
2492 lib/silcutil/silcnet.h.
2494 * Added includes/silcwin32.h for WIN32 specific includes
2497 * Do not use ptime structure or any of the posix process
2498 functions on WIN32 in lib/silccrypt/silrng.c.
2500 * Added silc_gettimeofday to provide generic function
2501 for struct timeval on all platforms. Added the function
2502 to lib/silcutil/silcutil.h.
2504 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2507 library as they clearly belong there. As a plus side we
2508 can make the actual socket connection routines platform
2511 Added also new generic function silc_socket_read and
2512 silc_socket_write (that used to be silc_packet_[read/write].
2513 The implementation of these are platform specific.
2515 * Added WIN32 specific routines of silc_socket_[read/write]
2516 to lib/silcutil/win32/silcwin32sockconn.c.
2518 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2520 * Added preliminary support for native WIN32 compilation under
2521 cygwin (using the -mno-cygwin option for GCC) to the
2522 ./configure.in.pre. The --with-win32 now prepares the
2523 compilation for native WIN32.
2525 * Rewrote the SILC Scheduler interface in the file
2526 lib/silcutil/silcschedule.h. The scheduler is now context
2527 based and does not have anymore any global static scheduler.
2528 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2529 and created lib/silcutil/win32 directory for WIN32 based
2532 * Added Unix specific network routines to the
2533 lib/silcutil/unix/silcunixnet.c and the old
2534 lib/silcutil/silcnet.c includes now only generic routines.
2536 Added WIN32 specific network routines to the
2537 lib/silcutil/win32/silcwin32net.c.
2539 * Added Unix specific utility functions from the
2540 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2542 * Added WIN32 SILC Scheduler to the file
2543 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2546 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Do not handle JOIN notify in the server if the target client
2549 is not registered (idata->registered == FALSE). The affected
2550 file is silcd/packet_receive.c.
2552 * Update the nickrec->founder in event_cumode in the Irssi SILC
2553 client. Affected file irssi/src/silc/core/silc-channels.c.
2555 * Fixed the CUMODE_CHANGE notify handling in the server when
2556 server and router are announcing their clients on channels.
2557 Now the mode changes are saved and notified correctly. The
2558 affected file is /silcd/packet_receive.c.
2560 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2561 They really did not replace the cache entry in the ID Cache.
2562 Now they do that. Affected file silcd/idlist.c.
2564 * Fixed the KICK notify handling in the Irssi SILC client to
2565 update the channel records so that the kicked client does not
2566 appear to be on the channel. The affected file is
2567 irssi/src/silc/core/silc-channels.c.
2569 * Always update the conn->current_channel when executing command
2570 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2572 * Fixed the KILL notify handling in Irssi SILC client to remove
2573 the killed client on all channels.
2575 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Fixed the silc_parse_command_line to remove extra spaces
2578 from the start and end of the arguments. Affected file is
2579 lib/silcutil/silcutil.c.
2581 * Cancel and free any active protocol in the function
2582 silc_server_close_connection. Affected file silcd/server.c.
2584 * Cancel and free any active protocol in the function
2585 silc_client_close_connction. Affected file is
2586 lib/silcclient/client.c.
2588 * Do not execute the KILL command for clients that are in
2589 history (ie. they are not in the network). Affected file is
2592 * Fixed KILL notify handling, client does not crash anymore.
2593 Affected file irssi/src/silc/core/silc-channels.c.
2595 * Reduced the default packet buffer size from 2048 to 1024 in
2596 lib/silccore/silcpacket.c.
2598 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2599 counter to the SKE context that is incresed when the SKE library
2600 performs async operation outside the library. If the outside
2601 process frees the SKE context and FREED status will be set
2602 and the library will detect after the sync operation that the
2603 libary is freed. The affected files are
2604 lib/silcske/silcske[_status].[ch].
2606 * Resolve the client entry information in the function
2607 silc_client_channel_message to assure that NULL pointer is not
2608 passed as client entry to the application. */
2610 * Fixed the task timeout calculation to assure that there is
2611 never negative timeouts. The affected file is
2612 lib/silcutil/silcschedule.c.
2614 * Fixed the channel user mode notification sending in server.
2615 It was sent point-to-point to the router (or to server by router)
2616 but it needs to be destined to a channel. The routines now
2617 supports sending the channel user mode notifys to the channels
2618 when announcing clients and channels. Affected files are
2619 silcd/server.c and silcd/packet_receive.c.
2621 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2622 It did not actually replace the old channel entry in the cache.
2623 Affected file lib/silcclient/client_notify.c.
2625 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Fixed a possible crash in silc_packet_send_prepare. It now
2628 assures always that there is enough space in the buffer and
2629 at the tail area of the buffer (for MAC).
2631 Fixed the inbound buffer reallocation in silc_packet_read.
2632 It was old code and did not handle the reallocation correctly.
2635 The affected file is lib/silccore/silcpacket.c.
2637 * Fixed buffer overflow in silc_parse_nickname in the file
2638 lib/silcutil/silcutil.c.
2640 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2642 * make install generates new server keys only if there is not
2645 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2648 Added check that if the NOREPLY is set then we will not send
2649 the away message. This avoids infinite loop of away messages
2650 if both clients are away. The affected file is
2651 lib/silcclient/client_prvmsg.c.
2653 * Fixed client crash if /NICK was given without arguments.
2654 Affected file lib/silcclient/command.c.
2656 * Server does not send the invite list in INVITE command back
2657 to the client if the list was not altered. Added this notion
2658 to the protocol spec as well. Affected file silcd/command.c.
2660 Fixed possible crash in INVITE command by checking the
2661 value of silc_server_get_client_route command.
2663 * Fixed the INVITE notify type handling. The arguments are now
2664 taken in correct order and client does not crash. The affected
2665 file is irssi/src/silc/core/silc-channels.c.
2667 Removed the "Inviting xxx to channel" message from the
2668 client library away and let the application handle it.
2669 Affected file lib/silcclient/command.c. Added that message
2670 to Irssi SILC client's message formats.
2672 * Fixed CMODE command crash in client. It now checks the
2673 amount of arguments correctly and does not crash. The affected
2674 file is lib/silcclient/command.c.
2676 * Do not create new channel automatically in silc_channels_join
2677 but check whether the channel by that name already exists.
2678 Affected file irssi/silc/core/silc-channels.c.
2680 * Do not send the SERVER_SIGNOFF to router if the disconnected
2681 entity was the router. Affected file silcd/server.c.
2683 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2684 SILC client as it was missing from there.
2686 Added the handling of the KICK notify to the Irssi SILC client
2687 as it was missing. Added "you have been kicked" message to
2688 Irssi SILC client's message modules formats.
2690 Added the handing of the KILL notify to the Irssi SILC client
2691 as it was missing. Added the kill message module formats
2694 The affected file is irssi/src/silc/core/silc-channels.c.
2696 * The router did not save the channel mode the server announced.
2697 Affected file silcd/packet_receive.c.
2699 * Fixed a possible crash in INFO command in server. If the
2700 server did not provide the server info it crashed. Affected
2701 file silcd/command.c.
2703 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * Fixed the GETKEY command in the server to check also the
2706 global list. Otherwise the GETKEY would not work correctly
2707 in normal SILC server. Affected file silcd/command.c.
2709 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Fixed GETKEY crash, it crashed if the command did not succseed.
2713 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2716 is now real and not just an macro interface to GMP.
2718 Removed the entire GMP from the source tree and imported new
2719 NSS MPI library instead. Reason for removing GMP is that it is
2720 extremely large and compiles extremely slow. The NSS MPI
2721 is only a few files and compiles in less than 10 seconds.
2722 The speed is also about the same as GMP. The MPI is imported
2723 to lib/silcmath/mpi.
2725 If the system has GMP installed we will still use the GMP.
2726 If it is not then the NSS MPI will be compiled.
2728 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2730 * Merged a long nickname (127 characters long) crash bugfix from
2731 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2733 * Merged a freed memory reference bugfix from Irssi CVS tree.
2734 Affected file irssi/src/core/commands.c.
2736 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Added the server's public key sving and verification to the
2739 server when performing the SKE. This was missing and the
2740 remote server's (or router's) public key was accepted without
2741 checking whether we have it previously or trust it at all.
2742 Affected file silcd/protocol.c.
2744 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * Check in the silc_server_timeout_remote if protocol is active
2747 and make sure that the protocol's final callback is called so
2748 that all memory if freed. Affected file silcd/server.c.
2750 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * silc_server_whois_send_reply crashed the server if the nickname
2753 was 127 characters long. Affected file silcd/command.c.
2755 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2757 * Added sanity check to the silc_server_new_client. If the hostname
2758 is provided inside username then check that the provided hostname
2759 really is the same as the resolved one. If the hostname was not
2760 resolved then check it from the public key. Affected file is
2761 silcd/packet_receive.c.
2763 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2764 if the server disconnected us and the connection is not valid
2765 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2767 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2768 the library to the lib/silcutil/silcutil.[ch].
2770 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Close log file after open. Affected file
2773 lib/silcutil/silclog.c.
2775 * Check whether sock == NULL in silc_client_send_packet and return
2776 if it is. Affected file lib/silcclient/silcclient.c.
2778 * Check rec->entry == NULL in the Irssi SILC Client before
2779 sending the channel message. Affecte file is
2780 irssi/src/silc/core/silc-servers.c.
2782 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Merged a splitted window bugfix from Irssi CVS tree. The
2785 affected file is irssi/src/fe-text/textbuffer-view.c.
2787 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2788 It did not print nickname.
2790 * Improved the distributions system a bit.
2792 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2795 irssi/src/fe-text/gui-window.c.
2797 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2798 to in-active server. The affected file is
2799 irssi/src/silc/core/client_ops.c.
2801 * Resolve the client in USERS command reply if the entry does
2802 not have username resolved. The affected file is
2803 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2804 command to WHOIS command to really resolve stuff. The USERS
2805 is not used any more in any critical section so WHOIS can
2806 be used even though it might be slower than IDENTIFY.
2808 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2811 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2813 * Changed the protocol API a bit more consistent in the
2814 lib/silccore/silcprotocol.[ch].
2816 * Changed the following headers to ROBODoc format:
2818 lib/silccore/silcpayload.h
2819 lib/silccore/silcprotocol.h
2820 lib/silccore/silcsockconn.h
2822 All core library headers are now formatted.
2824 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Fixed a bug in Irssi SILC client; do not show that you are
2827 server/router operator if you really are not. Affected file is
2828 irssi/src/silc/core/client_ops.c.
2830 * Renamed silc_command_free_payload to silc_command_payload_free.
2831 Affected file lib/silccore/silccommand.h
2833 * Added silcmath.h to include the prototoypes of various routines
2834 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2837 * Changed the following headers to ROBODoc format:
2839 lib/silccore/silcchannel.h
2840 lib/silccore/silccommand.h
2841 lib/silccore/silcid.h
2842 lib/silccore/silcidcache.h
2843 lib/silccore/silcmode.h
2844 lib/silccore/silcnotify.h
2845 lib/silccore/silcpacket.h
2846 lib/silcmath/silcmath.h
2848 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Added checking to the server code not to start the server if
2851 ciphers and stuff are not configured properly. Affected files
2852 silcd/serverconfig.[h] and silcd/server.c.
2854 * Changed the layout of the header files of the public interfaces
2855 in the SILC libraries. The new layout supports ROBODoc
2856 documentation tool (and some others) so that it is easy to create
2857 a library reference manual. All the other headers and source
2858 code must still follow the CodingStyle document. Also source
2859 code must not include these ROBODoc stuffs, only the headers.
2860 Furthermore, all public interface headers must now be named
2861 by using `silc' prefix, example: silcapi.h, silccipher.h.
2862 Some files were renamed due to this. All the other headers
2863 must not be used as public interfaces. I will update the
2864 CodingStyle document later. Changed following headers, so far:
2866 lib/silcclient/silcapi.h
2867 lib/silccore/silcauth.h
2868 lib/silccore/silcprivate.h
2869 lib/silccrypt/silcdh.h
2871 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2875 * Removed silc_client_packet_send_flush from the client library
2876 as it is not needed. Affected file lib/silcclient/client.[ch].
2878 * Added printing of message of unresolved authentication method
2879 to the Irssi SILC client. Added it to the module formats.
2880 Removed the same message from the client library.
2882 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Added new distribution feature, DISTLABEL. Every distribution
2885 can define own preprocessor label that can be used in the
2886 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2887 file distributions, acconfig.h.pre and prepare.
2889 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Added Makefile.defines_int to include the actual definitions
2892 for Makefile.defines.in. Tested the new distribution system,
2893 created distributions and tested installation.
2895 * Added AWAY message printing to the Irssi SILC client. Added
2896 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2898 * Added SCONNECT command to call the SILC's CONNECT command.
2899 Cannot use CONNECT directly since Irssi uses that internally.
2900 Affected file irssi/src/silc/core/silc-servers.c.
2902 Added ACTION local command. It is same as ME command but takes
2903 the channel as mandatory argument.
2905 Rewrote some of the Irssi's help files to suite for SILC
2908 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added Makefile.defines[.in] that should for now on be included
2911 in all Makefile.am file in the source tree. That file includes
2912 all common compilation definitions for SILC source tree.
2914 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Minor changes to the ./prepare script to change the package
2917 name according the distribution name to the configure.in.
2919 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Created new distribution system. Added file `distributions'
2922 that defines all the distributions that can be created out of
2923 the SILC source tree. The ./prepare script now reads that
2924 file to determine how to prepare the distributions. The
2925 first argument to the ./prepare is the name of the distribution
2926 and second is the version of the distribution. If given
2927 without arguments it creates the default (toolkit) distribution
2928 with the default version (defined in ./prepare).
2930 All Makefile.am files that are subject to the distributions
2931 are now named as Makefile.am.pre. These are ./Makefile.am
2932 and lib/Makefile.am. Others may be changed later.
2934 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Added invite list, ban list, some key management and connection
2937 error message printing to module formats in the Irssi SILC client.
2939 * Added new silc_client_set_away_message to set the away message
2940 that is back to the person who sent private message. The
2941 affected file lib/silcclient/silcapi.h and the
2942 lib/silcclient/client_prvmsg.c.
2944 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Fixed the private message sending in the Irssi SILC client,
2947 added local command KEY to the Irssi SILC client.
2949 Added key management and key agreement message formats to the
2950 irssi/src/fe-common/silc/module-formats.[ch].
2952 Added USERS (alias WHO) printing, server/router operator
2953 indication and LIST command printing to the module formats.
2955 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Fixed channel joining notify handling, cumode notify handling
2958 from Irssi SILC client.
2960 * Added SILC specific module-formats to the Irssi SILC client so
2961 that SILC specific message hilighting, colors etc is possible.
2962 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2964 Added channel mode, channel user mode, actions, notices,
2965 whois and whowas printing to the the module-formats.c.
2967 * Fixed a bug in channel deletion in the server. The channel
2968 is not left to the cache even if the channel founder auth mode
2969 is set when there are no users anymore on the channel. Affected
2970 file silcd/server.c.
2972 * The silc_net_localhost now resolves the entire hostname including
2973 the domain name. Affected file lib/silcutil/silcnet.c.
2975 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Changed the ask_passphrase client operation to be ascynchronous.
2978 It has now a completion callback and a context that the
2979 application must call after it has got the passphrase from
2980 the user. Affected files lib/silcclient/silcapi.h,
2981 lib/silcclient/protocol.c, lib/silcclient/command.c and
2984 Added SilcAskPassphrase callback that the application calls
2985 to deliver the passphrase to the library.
2987 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2988 The public key verification and especially a certificate
2989 verification is asynchronous procedure.
2991 Added new SILC_SKE_STATUS_PENDING status to indicate the
2992 request is pending and a callback will be called to finalize
2995 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2996 indicate that remote end did not send its public key (or
2997 certificate), even though we require it. Added check for this
2998 condition in the SKE. This was a security bug, now fixed.
3000 Defined new SilcSKEVerifyCbCompletion callback that is called
3001 when the verification process is completed.
3003 The affected files lib/silcske/silcske_status.h and
3004 lib/silcske/silcske.[ch].
3006 * Changed the verify_public_key client operation to be async
3007 as well. Defined SilcVerifyPublicKey callback that is used to
3008 indicate the success of the public key verification process.
3010 Changed the server and client to use the new async client
3013 * Changed the Irssi SILC client's internal scheduler to be called
3014 twice as many times as it used to be. As a result the client
3015 should be a bit faster now. Affected file is
3016 irssi/src/silc/core/silc-core.c.
3018 * Added support to Irssi SILC client of asynchronous public key
3019 verification and passphrase inquiry. Affected file is
3020 irssi/src/silc/core/silc-core.c.
3022 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3024 * Do not say "You have left channel %s" in client library.
3025 Moved it to the application. Affected files are
3026 lib/silcclient/command.c and silc/client_ops.c.
3028 * Fixed silc_client_get_clients. Command context was not
3029 duplicated and was freed memory in the callback. Affected
3030 file lib/silcclient/idlist.c.
3032 * Do not say "you are now talking..." on JOIN command in the
3033 client library. The appliation must handle it.
3035 * Do not say ".. changed topic to" in command reply in the
3036 client libary. The application must handle it.
3038 * Fixed TOPIC command sending in the client library.
3040 * Fixed a memory leak in silc_client_command_free in the file
3041 lib/silcclient/command.c.
3043 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3045 * Imported a modified version of Irssi client to the source tree.
3046 The Irssi will be used to create a new client called
3047 Irssi SILC. Imported to irssi/.
3049 Added silc_core_init_finish function to the Irssi. Affected
3050 file irssi/configure.in.
3052 A lot changes in the Makefile.ams around the irssi tree.
3054 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Do not rehash if the new size is same as the old size of the
3057 hash table, in the silc_hash_table_rehash*. The affected file
3058 lib/silcutil/silchashtable.c.
3060 * Replaced hash_table_del_by_context calls from the server
3061 (when channel->user_list and client->channels) to the
3062 hash_table_del as it is sufficient and faster.
3064 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Added silc_hash_table_list, silc_hash_table_get and the
3067 SilcHashTableList structure to provide an alternative way to
3068 traverse the hash table. The affected files are
3069 lib/silcutil/silchashtable.[ch].
3071 * Changed the server's idlist routines to use the hash table
3072 routines to optimize the code.
3074 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Replaced the client entry's `channel' list and channel entry's
3077 `user_list' list to hash tables for optimized lookup. Changed
3078 the code to use the hash table interface around the code.
3079 Affected file lib/silcd/idlist.[ch].
3081 * Added `auto_rehash' boolean argument to the function
3082 silc_hash_table_alloc to indicate whether the hash table should
3083 auto-rehash when it thinks is appropriate time. It will
3084 increase the hash table size if the there is twice as much
3085 entries in the table than the size of the table, and will
3086 decrease the size if there are twice as less entries than
3087 the size of the table.
3089 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3091 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3093 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * silc_idcache_purge_by_context deletes the entry now by context
3096 as it is supposed to do. Affected file lib/silccore/idcache.c.
3098 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3099 client is not anymore valid (WHOWAS givens the info) and not
3100 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3102 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Removed the `data' and `data_len' arguments from the ID Cache
3105 interfaces and added `name' argument. ID Cache does not handle
3106 anymore the binary data only a names associated with given ID.
3108 * When hashing a Client ID with silc_hash_id the entire ID is
3109 not hashed anymore, instead only the hash of the Client ID is
3110 hashed. This way we can access the Client ID from the cache
3111 with Client ID but with the hash of the ID (which is a hash of
3112 the nickname) as well without any difference in performance.
3114 Added also silc_idcache_find_by_id_one_ext to do one on one
3115 searching when we have the actual ID. Added also function
3116 silc_hash_client_id_compare. The affected files are
3117 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3119 * When hashing the name associated with a ID it is always done
3120 in lowercase. This way we can access the cache without worrying
3121 about case-sensitivity, even though, for example nicknames are
3124 * Fixed a bug in server with channel message sending. It put
3125 wrong ID type as destination ID. The affected file
3126 silcd/packet_send.c.
3128 * silc_idcache_del_by_context now deletes from all hash tables
3129 by context. Affected file lib/silccore/idcache.c.
3131 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3133 * Changed the client library to use the new ID Cache interface.
3134 Changes around the source tree.
3136 * Added silc_hash_table_rehash_ext to rehash with specific
3137 hash function. Affected file lib/silcutil/silchashtable.[ch].
3139 * Added silc_hash_string_compare to compare two strings in the
3140 hash table. Affected file lib/silcutil/silcutil.[ch].
3142 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Added new function silc_idcache_del_by_context into the
3145 lib/silccore/idcache.[ch].
3147 * Changed the server's ID list routines to use the new ID Cache
3148 interface. Changes around the source tree.
3150 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3152 * Added silc_hash_table_del[_by_context]_ext functions in to the
3153 lib/silcutil/silchashtable.[ch].
3155 Removed silc_hash_table_find_all* routines and added new
3156 silc_hash_table_find_foreach to replace them.
3158 Added silc_hash_table_replace_ext function as extended
3159 replacing function. Separated the simple hash table interface
3160 from the extended hash table interface in the file
3161 lib/silcutil/silchashtable.h.
3163 * Fixed minor bugs and changed it to use some of the new
3164 hash table functions in lib/silccore/idcache.c
3166 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3168 * Added new function silc_hash_table_find_all to return all keys
3169 in the hash table by the specified key. As the hash table is
3170 collision resistant it also makes it possible to have several
3171 duplicate keys in the hash table. This function may be used to
3172 find all of the keys from the hash.
3174 Added user_context arguments to the SilcHashFunction,
3175 SilcHashCompare and SilcHashDestructor to deliver user specified
3178 Added new fuctions silc_hash_table_find[_all]_ext to do
3179 extended lookup with specified hash and compare functions and
3180 specified user contexts.
3182 Added new function silc_hash_table_add_ext to add the key
3183 with specified hash function and user context.
3185 Added new function silc_hash_table_foreach to traverse all
3186 entrys in the hash table. Added SilcHashForeach callback
3189 Added new function silc_hash_table_del_by_context to delete
3190 the entry only if the context associated with the key matches.
3192 Affected files are lib/silcutil/silchashtable.[ch].
3194 * Removed silc_hash_[server/client/channel]_id and added just
3195 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3196 silc_hash_id_compare to compare two ID's using as the hash table
3197 comparison function. Added also silc_hash_data to hash
3198 binary data and silc_hash_data_compare to compare it.
3200 * Removed silc_idlist_find_client_by_hash as it is not needed
3201 anymore. Affected file silcd/idlist.[ch].
3203 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3204 to use internally the SilcHashTable. The new ID Cache is a lot
3205 faster than the old one. Some of the ID Cache interface was also
3206 rewritten and obsolete and stupid functions were removed.
3208 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Added entry_count field to the SilcHashTable to keep the number
3211 of the entries in the table. Implemented the function
3212 silc_hash_table_rehash. Added new function
3213 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3215 Fixed a minor bug in silc_hash_table_free.
3217 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3218 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3219 into the lib/silcutil/silcutil.[ch].
3221 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3223 * Implemented a collision resistant hash table into the
3224 lib/silcutil/silchashtable[ch]. See the header and the source
3225 for the SilcHashTable API.
3227 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3229 * Merged dotconf version 1.0.2 into lib/dotconf.
3231 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Do not compile anything in lib/silcsim/* if the SIM support
3234 is not enabled. The tree should now compile without problems
3237 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Compiled the SILC under cygwin. Compiled and tested briefly
3240 without problems. More tests needed. The SIMs didn't compile
3243 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3245 * Fixed possible crash in silc_get_username in the
3246 lib/silcutil/silcutil.c.
3248 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Fixed a va_arg in silc/client_ops.c.
3252 * Oops, RC5 routines were named AES and caused some problems
3253 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3255 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Added new SilcIDIP structure into the lib/silccore/id.h and
3258 replaced the old `ip' fields from all SILC ID's to that type.
3259 This is a step towards IPv6 support.
3261 The silc_id_get_len takes now the ID as an extra argument.
3262 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3263 both IPv4 and IPv6 based ID's.
3265 The affected files are lib/silccore/id.[ch] and other files
3266 around the tree using these routines.
3268 * Removed the ID length arguments in server from various
3269 silc_server_send_notify_* routines -> they are not needed
3272 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3274 * Fixed memory leak in silc_encode_pem_file in the file
3275 lib/silcutil/silcutil.c.
3277 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Check minor version as well in the SKE. Affected files are
3280 silcd/protocol.c and lib/silcclient/protocol.c.
3282 * Added --identifier option to the server so that an identifier
3283 can be when creating the public key for the server. Affected
3284 file is silcd/silcd.c.
3286 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3287 lib/silccrypt/silcpkcs.c.
3289 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3291 * Register default ciphers and stuff when using -C option with
3292 the server. Affected file sildc/silcd.c.
3294 * Put back the servers public key filename format, it is better
3295 than the new one. For now, the client keys are saved with the
3296 new filename format. The affected file silc/client_ops.c.
3298 * Implemented the Cipher API for the rest of the ciphers that
3299 did not implement it or implemented it the wrong way.
3301 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Register default ciphers and stuff when using the -S option
3304 in the client. Affected file silc/silc.c. Same also when
3305 creating new key pair with -C option.
3307 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Fixed the silc_verify_public_key client operation function to
3310 save the public keys differently. The fingerprint is now
3311 used as filename and not the hostname. This way also the
3312 client keys are saved uniquely and not with hostnames. The
3313 affected file is silc/client_ops.c.
3315 * Trimmed the silc_hash_fingerprint function to remove extra
3316 whitespaces from the end of the fingerprint. The affected
3317 file is lib/silccrypt/silchash.c.
3321 * Added silc_cipher_register_default function to register all
3322 default ciphers. It can be used when configuration files
3323 does not exist and the application does not want any specific
3324 ciphers in any specific order.
3326 The SilcDList is now used as silc_cipher_list dynamically
3327 allocated cipher list. Removed the static list all together
3328 and now all ciphers must be allocated to the dynamic list.
3329 The silc_cipher_alloc routine was changed to check only the
3332 All silc_cipher_* routines that used to return int returns
3335 The affected files lib/silccrypt/silccrypt.[ch].
3337 * The same thing was done to silc_hash_* as for silc_cipher_*
3338 routines. Affected files lib/silccrypt/silchash.[ch].
3340 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3341 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3342 Added also silc_pkcs_[un]register[_default] functions.
3343 Removed the data_context from the PKCS API.
3345 * Added silc_hmac_register_default function to register default
3346 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3347 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3348 to unregister all hmacs at once.
3350 * Register the default ciphers, hash functions, PKCSs and HMACs
3351 if client's configuration file does not exist. The affected
3354 * The client did not load the hash functions from the SIM
3355 modules at all. Added support for this. Affected file is
3356 silc/clientconfig.c.
3358 * When decoding public key with silc_pkcs_public_key_decode, check
3359 the supported algorithm only if PKCS are registered. Affected
3360 file lib/silccrypt/silcpkcs.c. The same was done with the
3361 silc_pkcs_private_key_decode.
3363 * Fixed the SILC List routines to keep the list always in order.
3364 It used to change the list's order when traversing the list but
3365 not it preserves the order. Affected file lib/trq/silclist.h.
3367 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Added the client library to use the SilcSocketConnection's
3370 reference counter (by silc_socket_dup) to prevent the bug that
3371 the socket object may be freed underneath async operation.
3373 * The name resolv library checking fixes in the configure.in.pre.
3376 * Created new version of the protocol drafts for future
3377 development. The -03 drafts are the ones that will be changed
3378 in the trunk now and the -02 will remain as they are.
3380 * Send list of CUMODE notifys to the router when announcing
3381 the channel users to the router. Affected file silcd/server.c.
3382 If the router receiving channel founder CUMODE for a channel
3383 that already has channel founder it will send CUMODE notify
3384 to the sender to remove the channel founder rights from the
3385 announced client. Affected file silcd/packet_receive.c.
3387 * The CUMODE notify may now use Server ID as well as the entity
3388 who changes the mode. Updated protocool specs.
3390 * Updated INSTALL and README files.
3392 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * New web pages in the http://silc.pspt.fi. The pages was
3399 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Implemented the [DenyConnectin] config section in the server.
3402 Added silc_server_config_denied_conn to check whether incoming
3403 connection is denied. Affected file silcd/serverconfig.[ch].
3405 * Do not check the ports when checking the incoming configuration
3406 data if the port is 0, meaning any. Affected file is
3407 silcd/serverconfig.c.
3409 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Fixed buffer overflow in silc_string_compare in the file
3412 lib/silcutil/silcutil.c.
3414 * Fixed double free in silc_server_command_leave in the file
3417 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Fixed the version checking in the server. Affected file is
3422 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Fixed the configuration data fetching when accepting new
3425 connections in the server. Affected file silcd/server.c.
3427 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Added `sender_entry' argument to the function
3430 silc_server_packet_relay_to_channel so that we can check
3431 whether some destination actually belongs to the same route
3432 the sender belongs (ie, we must not resend the packet to the
3433 sender). Affected file silcd/packet_send.[ch].
3435 * Added `servername' field to the SilcClientEntry in the server
3436 to hold the name of the server where client is from. Affected
3437 file is silcd/idlist.h.
3439 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3441 * Moved the channel message encrypting in the router betwen
3442 router connections from silc_server_channel_message to the
3443 silc_server_packet_relay_to_channel since we want to check
3444 whether we have anybody channel before encrypting anything.
3445 Affected files silcd/packet_[receive/send].c.
3447 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3449 * Fixed the [AdminConnection] server config section to support
3450 multiple entries. Affected file silcd/serverconfig.c.
3452 * Added support into the server to check the validity of the
3453 incoming connection before executing any KE or authentication
3456 * The connection configuration is now saved to the KE and
3457 connection auth protocol contexts and not fetched anymore in
3458 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3460 * The local hosts listenning address and port is also resolved
3461 now when starting the server. We want to have the socket object
3462 to include the real address and port for the listener. Added
3463 new function silc_net_check_local_by_sock into the files
3464 lib/silcutil/silcnet.[ch].
3466 * Fixed a broadcast bug in server -> do not broadcast if we
3469 * Fixed a routing bug. Do not route broadcast packets ever.
3470 Broadcast packets must be processed always and not routed since
3471 they may be destined to some other host than yourself and thus
3472 would get routed without no good reason. Affected file is
3475 * Added function silc_server_config_is_primary_route to check
3476 whether primary router connection has been configured (a router
3477 configuration that we are initiating). If there is not, we
3478 will assume that there is only two routers in the SILC network
3479 and we will use the incoming router connection as our primary
3480 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3482 * Changed the order of the broadcasting. Broadcast _after_ the
3483 packet has been processed not before. Affected file is
3486 * Fixed a [ClientConnection] parsing bug. The port was never
3487 parsed correctly thus resulting to port 0. Affected file
3488 silcd/serverconfig.c.
3490 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3491 argument and did not set the broadcast packet flag. Affected
3492 file silcd/packet_send.c. Fixed same bug in the function
3493 silc_server_send_notify as well.
3495 * If we receive NEW_ID packet for our own ID in the server, ignore
3498 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Removed the nickname from the Private Message Payload.
3503 Updated the code and the protocol specs.
3505 * Updated protocol specs for submitting to the IETF.
3507 * Tweaked the Random Number Generator a bit. Affected file
3508 lib/silccrypt/silcrng.c. Exported a new function
3509 silc_rng_[global]_add_noise which can be used to add more
3512 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Do not parse packets with different timeout when protocol
3515 is active -> may cause problem with rekey. Affected file
3518 * When server receives signoff notify it must not create
3519 new channel key if the client is on any channels since the
3520 sender of the signoff notify will create it.
3522 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Added printing of error messages during SKE protocol from the
3525 failure packet sent by server during SKE. Affected file
3528 * Removed the client's failure_callback handling with timeout
3529 and handle it immediately when received.
3531 * The SKE library returned wrong type in SUCCESS and FAILURE
3532 packets. They must be 32 bit MSB not 16 bit MSB.
3534 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Ok, rewrote the logic of the re-key and now it seems to work.
3537 I tested it on high traffic with frequent re-keys without
3538 problems. Added hmac_receive (and renamed hmac to hmac_send)
3539 in SilcClientConnection in lib/silcclient/client.h and
3540 in SilcIDListData in silcd/idlist.h. Also, removed the
3541 SilcPacketParserContext's cipher and hmac fields as they are
3542 not needed anymore and actually caused some problems when
3543 the ciphers and hmac's changed underneath the packet parser.
3545 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * If re-key protocol is active then process the incoming packets
3548 synchronously since we must assure that icoming packets encrypted
3549 with the old key is processed before the new keys is set to
3550 use. This is true other packets than for REKEY packets.
3551 Affected file silcd/server.c. The same was done to client library
3552 as well, affected file lib/silcclient/client.c.
3554 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Fixed bug in client and server to accept the force send if
3557 the packet is send from silc_[server/client]_packet_process
3558 function. Otherwise the packets are never delivered, oops.
3560 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Disable force sending of packets when REKEY protocol is active.
3563 We must assure that no packet is sent directly when rekey is
3564 performed. All packets must be sent through packet queue.
3565 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3566 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3567 function is silc_[server/client]_packet_send_real to check
3570 * Replaced the SIM paths from example config files to
3571 /usr/local/modules. Also, make install creates now
3572 /usr/local/silc/logs directory to hold all the SILC server
3575 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3577 * Made the configure.in.pre work on Solaris. Patch by salo.

3584 * Fixed the make install.
3586 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * When MAC computation fails the silc_packet_decrypt returned 0
3589 even though it was supposed to return -1. Fixed this. The
3590 affected file is lib/silccore/silcpacket.c.
3592 * Do not replace the config files in /etc/silc (in make install)
3593 if they already exist. Affected file ./Makefile.am.
3595 * Do not send re-key packets immediately but through packet queue.
3596 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3598 * Changed silc_net_check_host_by_sock to return FALSE if the
3599 IP/DNS could not be resolved. Though, it returns the IP address
3600 now even if it could not resolve it (but returns also FALSE).
3601 Affected file lib/silcutil/silcnet.[ch].
3603 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Added silc_pkcs_decode_identifier to decode the public key's
3606 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3607 Added also silc_pkcs_free_identifier. Added also new context
3608 SilcPublicKeyIdentifier.
3610 * Added -S option to the silc client. It is used to dump the
3611 contents of the specified public key file.
3613 * Changed the PKCS api to return the public key length when
3614 setting the public key.
3616 * Fixed a fatal bug in the public and private key file loading.
3617 Affected file lib/silccrypt/silcpkcs.c.
3619 * Execute the packet parsing for client with zero (0) timeout
3620 if the protocol is active. Affected file silcd/server.c.
3622 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Made the key generation options to the silcd program. Added
3625 -C option, equivalent to client's option.
3627 * Added new [ServerKeys] config section to the server. It
3628 configures the server's public and private key.
3630 * Defined generic Public Key Payload into the protocol
3631 specification to send specific type of public keys and
3634 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3635 public key or certificate.
3637 * Implemented the GETKEY command to the server and to the
3638 client library and on user interface.
3640 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Made preliminary `make install' work.

3671 SilcClientConnection structure; not needed. Affected file is
3672 lib/silcclient/client.h.
3676 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Do not ask whether user wants to use the negotiated private key
3679 for private messages, just use it. Affected file is
3680 silc/local_command.c.
3682 * Added `send_enc_key' and `enc_key_len' fields to the
3683 SilcIDListData structure since they are needed in the re-key

3707 * Changed _ALL_ unsigned long and unsigned int to uint32,
3708 unsgined short to uint16 in the source tree.
3710 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3711 not handle clients that has entry->data.registered == FALSE.
3712 They are not in the network anymore. Affected file is
3715 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3730 application. Affected file silc/client_ops.c.
3732 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3733 if the deleting was successful. Affected file silcd/idlist.[ch].
3735 * Added support for public key authentication in the connection
3736 authentication protocol in the client library. Affected file
3737 lib/silcclient/protocol.c.
3739 * Changed the server's silc_idlist_get_clients_by_* interface
3740 to support already allocated array so that new entries may be
3741 added to pre-allocated array. Affected file silcd/idlist.[ch].
3742 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3743 and command replies.
3745 * All command reply functions in the server now calls the
3746 pending command callback even if error occured. This way the
3747 error will be delivered to the client as well. Affected files
3748 silcd/command.c and silcd/command_reply.c.
3750 * Fixed INFO command to return local server's info if no server
3751 was provided. Affected file lib/silcclient/command.c.
3753 * Removed RESTART command for good. Updated the code and the
3756 * Rewrote parts of the task system. It is a bit simpler now.
3757 Removed unsued task priorities. The affected files are
3758 lib/silcutil/silctask.[ch].
3760 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Moved the USERS printing from the library to the application.
3763 Affected files lib/silcclient/command.c and silc/client_ops.c.
3765 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Added channel key re-key support. The re-key is perfomed
3770 only by the router and is done once in an hour. Added `rekey'
3771 field to the SilcChannelEntry in the server. Affected files
3772 silcd/server.c and silcd/idlist.h.
3774 * Added silc_task_unregister_by_context into the file
3775 lib/silcutil/silctask.[ch].
3777 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Added SILC_UMODE_GONE mode to indicate when the client is not
3780 present in the SILC network. Added also support to the local
3781 command AWAY that will set this mode. Added support of showing
3782 "xxx is gone" in WHOIS command. The USERS command shows the
3783 gone status as well.
3785 * Fixed setting server and router operator privileges in the
3786 server's UMODE command. Affected file silcd/command.c.
3788 * Merged the SKE KE1 and KE2 payloads into one payload. The
3789 new KE payload is equivalent to the old KE2 payload.
3791 Cleaned up the SKE Start Payload parsing. It now uses the
3792 simple buffer unformatting to do the parsing. A lot faster
3795 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3796 to the SKE that is used to indicate whether both of the SKE
3797 parties should perform authentication. By default only the
3798 responder performs authentication. By setting this flag also
3799 the initiator must do authentication. By default it is unset
3800 since in normal SKE case, client to server connection, only
3801 the responder should do authentication. When doing SKE between
3802 two clients both should perform authentication. Updated the
3803 code and the protocol specs.
3805 * A little fix to IDENTIFY command in the server. Search the
3806 client first by hash not nickname. Affected file is
3809 * Fixed the silc_client_close_connection to support closing
3810 the client to client connections wihtout deleting too much
3811 data. Affected file lib/silcclient/client.c.
3813 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3814 are received if protocol used to be active but is not anymore
3815 the application would crash due to NULL pointer dereference.
3816 Affected files silcd/server.c and lib/silcclient/client.c.
3818 * Added `hash' field to the SilcClientConnection to include
3819 the hash function negotiated in the SKE protocol.
3821 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3822 to set the channel founder authentication data. A client can
3823 claim the founder rights later by providing the authentication
3824 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3825 This way the channel founder can regain the channel founder
3826 privileges even it is left the channel. This works only on
3827 local server and the client must be connected to the same
3828 server to be able to regain the founder rights. Updated the
3829 protocol specs accordingly.
3831 Added support to the CMODE command in the client to set the
3832 founder auth data. Read the README to see how to set it.
3834 Added support to the CUMODE command to claim the founder
3835 rights. Read the README to see how to do it.
3837 Added support for the founder authentication to the Channel
3838 Entry in the server. Affected file silcd/idlist.h.
3840 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3841 server's CMODE command. Affected file silcd/command.c.
3843 * Added the following new functions into lib/silccore/silcauth.[ch]:
3844 silc_auth_get_method and silc_auth_get_data.
3846 * The server now saves the remote hosts public key to the
3847 SilcIDListData pointer. Affected file silcd/protocol.c.
3849 * The normal server now does not remove the channel entry from
3850 the cache if the founder authentication data is set. It used
3851 to remove it if the founder was the last one on the channel on
3852 the server and left the channel. The auth data is saved and
3853 if the channel is re-joined later the old entry is used with
3854 the old auth data. Affected files silcd/command_reply.c and
3857 * Removed the `pkcs' field from the SilcIDListData structure
3858 in the server; it is not used. Affected file silcd/idlist.h.
3860 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3862 * Fixed packet processing on slow links. Partial packets were
3863 never re-processed because the incoming data buffer was cleared
3864 by the application. Application must not directly clear the
3865 sock->inbuf, the packet processing routines handle it. Fixed
3866 this in client library and in server.
3868 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Fixed the WHOIS and IDENTIFY send reply function to really
3871 check whether to send list or just one entry. Affected file
3874 * Cleaned up the LEAVE command's channel key distribution. The
3875 affected file silcd/command.c.
3877 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3878 can enforce the channel mode as well. In that case the ID
3879 includes the ID of the server. The code now enforces the
3880 mode change if the router have different mode than the server.
3882 * The notify client operation with CMODE_CHANGE notify can now
3883 return NULL client_entry pointer if the CMODE was not changed
3884 by client. Application must check for this.
3886 * Added <Server ID> argument to INFO command to support server
3887 info fetching by Server ID.
3889 * Added silc_server_announce_get_channel_users to get assembled
3890 packets of channel users of the specified channel. Affected
3891 file silcd/server.[ch].
3893 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3894 was freed underneath the ID Cache.
3896 * Re-announce clients when the server received CHANNEL_CHANGE
3897 notify from the router. Affected file silcd/packet_send.c.
3899 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3902 crashed since it did not handle the fact that there is no cipher
3903 called "3" and didn't check the error condition. Now fixed.
3905 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3906 flag. It can be used to send message requests.
3908 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Implemented the RESTART command in the client.
3912 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3913 notice type messages. Added notice printing to the user
3916 * The channel keys are not re-generated if the channel's mode
3917 is PRIVKEY, ie private key on the channel exists. Affected
3918 files silcd/server.c and silcd/command.c.
3920 * Fixed a little bug in channel message delivery when channel
3921 private keys are set in the server. Affected file is
3922 silcd/packet_send.c.
3924 * Changed the setting on channel->on_channel = TRUE from the
3925 silc_client_save_channel_key to the JOIN command reply. The
3926 key payload is not received if the private channel key is set.
3927 Affected file lib/silcclient/command_reply.c and the
3928 lib/silcclient/client_channel.c.
3930 * When the CMODE_CHANGE notify is sent and the channel private
3931 key mode is removed the channel key must be re-generated in
3932 other cells as well. Added this support for the router in the
3933 silcd/packet_receive.c.
3935 * Added new local command NOTICE to send notice message on
3936 channel. Affected file silc/local_command.[ch].
3938 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Added new local command ME to the client. It is used to send
3941 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3942 some action. Affected file silc/local_command.[ch].
3944 * Changed channel_message and private_message client operations
3945 to deliver the message flags to the application. Added also
3946 the `flags' arguments to the silc_client_send_channel_message
3947 and silc_client_send_private_message functions. Affected file
3950 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Redefined the Private Message Payload to support private message
3953 keys and to support the new private message flags. Updated
3954 the protocol specs. Flags makes it possible to have for example
3955 CTCP style messages.
3957 * Added new type SilcPrivateMessagePayload and defined an API
3958 for it in the lib/silcclient/silcprivate.[ch].
3960 * Tested private message private keys successfully. Tested the
3961 private message key set, unset and list commands with the new
3964 * Redefined the Channel Message Payload to include the channel
3965 message flags (equal with private message flags) to support
3966 for example CTCP style messages.
3968 * Defined some of the message (for channel and private message)
3969 flags. Updated the protocol specs and added the flags to the
3970 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3972 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Added SilcKeyAgreementStatus type to the key agreement routines
3975 to indicate the current status and error if one occured.
3976 The status types are defined in the lib/silcclient/silcapi.h.
3978 * Added new local command KEY that is used to set and unset private
3979 keys for channels, set and unset private keys for private messages
3980 with remote clients and to send key agreement requests and
3981 negotiate the key agreement protocol with remote client. The
3982 key agreement is supported only to negotiate private message keys,
3983 it currently cannot be used to negotiate private keys for channels,
3984 as it is not convenient for that purpose.
3986 * Fixed a minor pending callback setting bug in the function
3987 silc_client_get_client_by_id_resolve, now the function works.
3988 Affected file lib/silcclient/idlist.c.
3990 * Added function silc_net_get_local_port to get local bound
3991 port by socket. Added to lib/silcutil/silcnet.[ch].
3993 * Added `sockets' and `sockets_count' fields to the SilcClient
3994 object. They hold the sockets of the listenning sockets in
3995 the client. Listenning sockets may be for example the key
3996 agreement server. Affected file lib/silcclient/client.[ch].
3997 Added functions the silc_client_add_socket and the
3998 silc_client_del_socket. They are exported to the application
4001 * Added ~./silc/clientkeys to support other client's public keys.
4003 * Renamed verify_server_key client operation to verify_public_key
4004 and added one argument to indicate the type of the connection
4005 (server, client etc.).
4007 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Added silc_server_connection_auth_request to handle the
4010 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4011 silcd/packet_receive.[ch].
4013 * Added silc_server_send_connection_auth_request into the
4014 silcd/packet_send.c to send the connection auth request packet.
4016 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4019 * Fixed the public key authentication in responder side in the
4020 server. The `auth_data' pointer includes the SilcPublicKey
4021 not the path to the public key. Affected file silcd/protocol.c.
4023 * Implemented the public key authentication in the initiator side
4024 in the server. Affected file silcd/protocol.c.
4026 * Removed the [RedirectClient] config section from the server
4027 configuration. Is not needed and I don't want to implement it.
4029 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4031 * Cleaned up the CMODE command in the server. It now works
4032 correctly and supports all the modes defined in the protocol.
4033 Affected file is silcd/command.c.
4035 * Added `hmac_name' field to the SilcChannelEntry in the server
4036 to hold the default HMAC of the channel. It can be set when
4037 creating the channel (with JOIN command). Affected files
4040 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4041 type to indicate the change of the current cipher and hmac
4042 on the channel. Client can safely ignore the <cipher> argument
4043 (if it chooses to do so) since the CHANNEL_KEY packet will
4044 force the channel key change anyway. The <hmac> argument is
4045 important since the client is responsible of setting the new
4046 HMAC and the hmac key into use.
4048 * Fixed the CMODE command in the client library as well.
4050 * Tested CMODE command in router environment successfully.
4052 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4054 * Show the version of the remote client (or server) when connecting
4055 to the server. It is logged to the log file. Affected file
4056 is silcd/protocol.c.
4058 * Fixed the KILLED notify handling in the client library. The
4059 client must be removed from all channels when receiving the
4062 Also, do not remove the client entry when giving the KILL
4063 command but when the KILLED notify is received.
4065 * Removed silc_idlist_find_client_by_nickname from the server.
4066 Not needed anymore. Affected files silcd/idlist.[ch].
4068 * Implemented the CHANNEL_CHANGE notify type handling to the
4069 server. Affected file silcd/server.c.
4073 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Added silc_server_send_notify_invite to send the INVITE
4076 notify between routers.
4078 * Implemented the INVITE command correctly to the server.
4080 * Implemented the INVITE notify type handling in the server.
4082 * Implemented the INVITE command to the client library and on the
4085 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4087 * Added function silc_server_get_client_resolve to find the
4088 client entry by ID from all ID lists and then resolve it
4089 (using WHOIS) if it cannot be found. Affected file is
4092 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Implemented the BAN command to the client library.
4096 * The JOIN command in the server now checks the invite list
4099 * Changed the silc_command_reply_payload_encode_va and the
4100 silc_command_payload_encode_va to support that if argument is
4101 NULL it ignores and checks the next argument. Affected file
4102 lib/silccore/silccommand.c.
4104 * Added silc_server_send_notify_ban to send the BAN notify
4105 type between routers.
4107 * Chaned the silc_notify_payload_encode to support that if
4108 argument is NULL it ignores and checks the next argument.
4109 Affected file lib/silccore/silcnotify.c.
4111 * Tested ban lists in router environment successfully.
4113 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Implemented BAN command to the server, in silcd/command.[ch].
4117 * Removed the BAN and INVITE_LIST modes from the CMODE command
4120 * Added function silc_string_match to regex match two strings.
4121 Affected files lib/silcutil/silcutil.[ch].
4123 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Redefined parts of the SilcChannelEntry in the server to support
4126 the new ban and invite lists.
4128 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Redefined the INVITE command. The same command can be used to
4131 invite individuals to the channel but also to manage the invite
4132 list of the channel (to add to and remove from the invite list).
4133 Updated the protocol specs.
4135 * Added new command SILC_COMMAND_BAN that can be used to manage
4136 the ban list of the channel. Updated the protocol specs.
4138 * Removed the channel modes: the SILC_CMODE_BAN and the
4139 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4140 in the CMODE command. The equivalent features are now available
4141 using INVITE and BAN commands. Updated the protocol specs.
4143 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4144 in the network about change in the current ban list. The notify
4145 type is not used by the client.
4147 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4148 support the invite lists.
4150 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Added new function silc_string_regexify that converts string
4153 including wildcard characters into regex string that can
4154 be used by the GNU regex library. Added into the file
4155 lib/silcutil/silcutil.[ch].
4157 Added silc_string_regex_combine to combine to regex strings
4158 into one so that they can be used as one regex string by
4159 the GNU regex library. Added into the file
4160 lib/silcutil/silcutil.[ch].
4162 Added silc_string_regex_match to match two strings. It returns
4163 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4165 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Imported GNU regex to the soruce tree into lib/contrib.
4168 Fixed some compiler warning from the regex.c.
4170 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Fixed MOTD command in the server to work in router environment.
4174 * Fixed the MOTD command in the client library to support
4175 the server argument in the command.
4177 * Added `nickname_len' argument to the silc_idlist_add_client
4178 in the server, as the `nickname' argument may be binary data
4181 * Added silc_idlist_get_channels to return all channels from
4184 * Implemented LIST command to the server. Affected file is
4187 * Implemented the LIST command to the client library and on the
4190 * Added [<user count>] argument to the LIST command reply.
4191 With private channels the user count is not shown.
4193 * Updated TODO and README.
4195 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * The client entry's data.registered must be TRUE even with
4198 global client entry on global client list. The data.registered
4199 is used to check whether the client is anymore in the network,
4200 for example with WHOWAS command so it must be valid.
4202 * Fixed the WHOWAS command in the server. It now actually works
4203 in router environment. Added function into silcd/command_reply.c
4204 silc_server_command_reply_whowas_save.
4206 * Added silc_idlist_purge function to the silcd/idlist.c
4207 to periodically purge the ID Cache.
4209 * Fixed INFO command in the server. It works now in router
4210 environment. Added <server name> argument to the INFO command
4211 reply. Updated the protocol specs.
4213 * Fixed minor bug in silc_idcache_purge to not purge if the
4214 expire value is zero.
4216 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4217 they were buggy because of the WHOWAS information.
4219 * Fixed local command MSG to handle the async resolving of
4220 the remote client properly. It used to fail the first MSG.
4221 Affected file silc/local_command.c.
4223 * Added `data_len' field to SilcIDCache context.
4225 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Update TODO. Todo in commands in the server.
4229 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4232 used by routers as broadcast packet to inform other routers
4233 about the changed user mode.
4235 Implemented the notify handling in the server. Affected file is
4236 silcd/packet_receive.c. Added the function
4237 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4239 * Added new generic Channel Payload and deprecated the New Channel
4240 Payload. The New Channel Payload is now the generic Channel
4243 * Added new argument `mode' to the silc_server_send_new_channel
4244 as it is required in the Channel Payload now.
4246 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4247 and created a new and real SilChannelPayload to represent the
4248 new generic Channel Payload. Implemented the encode/decode
4249 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4251 * Added silc_server_get_client_channel_list to return the list
4252 of channels the client has joined for WHOIS command reply.
4253 Affected file silcd/server.[ch].
4255 * Implemented the channel list sending in the WHOIS command reply
4256 in server and in the client.
4258 Implemented the channel list displaying on the user interface
4259 as well. Affected file silc/client_ops.c.
4261 * Added silc_channel_payload_parse_list to parse list of Channel
4262 Payloads. It returns SilcDList list of SilcChannelPayloads.
4263 Client for example can use this function to parse the list of
4264 channels it receives in the WHOIS command reply. The caller
4265 must free the list by calling silc_channel_payload_list_free.
4266 Affected files lib/silccore/silcchannel.[ch].
4268 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Added one new argument <user mode> to the WHOIS command reply
4271 to return the mode of the user in SILC. Updated the protocol
4274 Implemented it to the server and client.
4276 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Fixed the mode printing on the user interface on joining.
4279 Affected file silc/client_ops.c.
4281 * Implemented the UMODE command and user modes in general to the
4282 client library and to the user interface.
4284 * Implemented the UMODE command to the server.
4286 * The server now sends UNKNOWN_COMMAND error status if client sends
4287 unknown command. Affected file silcd/command.c.
4289 * All server commands now handle the command identifier the right
4290 way when sending the command reply to the client. The client can
4291 use to identify the command replies with the identifier.
4293 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Added silc_server_get_client_route to resolve the route to
4296 the client indicated by the client ID. Affected file is
4299 * Added silc_server_relay_packet as general function to relay
4300 packet to arbitrary destination. This deprecates functions
4301 like _send_private_message_key, _relay_notify etc. Affected
4302 file is silcd/packet_send.[ch].
4304 Removed silc_server_send_key_agreement,
4305 silc_server_send_private_message_key and
4306 silc_server_packet_relay_notify functions from the file
4307 silcd/packet_send.[ch].
4311 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4312 server. Affected file silcd/packet_receive.[ch].
4314 * Implemented the KILL command to the client. Implemented the
4315 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4316 Affected files lib/silcclient/command[_reply].c and
4317 lib/silcclient/client_notify.c. Implemented the KILL notify
4318 printing in the user inteface.
4320 * Fixed a lot silc_parse_nick memory leaks from the client
4321 library in the file lib/silcclient/command.c.
4323 * Changed the silc_server_send_notify_on_channels's `sender'
4324 argument from SilcSocketConnection to SilcClientEntry to
4325 check the sender as entry and not as connection object and not
4326 to send to the client provided as argument. The affected file
4327 is silcd/packet_send.[ch].
4329 * The notify packets that are destined directly to the client used
4330 to not to be processed by the server. Now changed that and the
4331 server processes all notify packets. After relaying the packet
4332 to the client the notify packet is processed in the server.
4334 * The silc_server_free_client_data now checks whether there is
4335 pending outgoing traffic for the client and purges the data to
4336 the network before removing the client entry.
4338 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4341 an client is killed from the SILC Network. Updated the protocol
4344 Added new function silc_server_send_notify_killed to the
4345 silcd/packet_send.[ch].
4347 * Added function silc_server_packet_relay_notify to relay notify
4348 packets that are destined directly to a client. In this case
4349 the server does not process the notify packets but merely relays
4350 it to the client. Affected file silcd/packet_send.[ch].
4352 Added also silc_server_packet_process_relay_notify to check
4353 whereto relay the notify. Affected file is
4354 silcd/packet_receive.[ch].
4356 * Implemented the KILL command to the server.
4360 * Added the backup schema desgined last fall to the protocol
4361 specs for everyone to see. The specification is in the
4362 *-spec-xx.txt draft and the packet type definitions for the
4363 backup routers is in *-pp-xx.txt draft. Thusly, added also
4364 new packet type SILC_PACKET_CELL_ROUTERS.
4366 * A big security problem in the implementation discovered. The
4367 signoff of an client did not cause new channel key generation
4368 which it of course should've done. The channel keys must be
4369 always re-generated when client leaves (or signoffs) the channel.
4370 The silc_server_remove_from_channels funtion now handles
4371 the channel key re-generation.
4373 * Added `sender' argument to the silc_server_send_notify_on_channels
4374 to not to send the client provided as argument. Affected file
4375 silcd/packet_send.[ch].
4377 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4379 * Implemented OPER and SILCOPER commands into the server and
4382 * Added silc_auth_verify and silc_auth_verify_data to verify
4383 the authentication directly from the authentication payload.
4384 It supports verifying both passphrase and public key based
4385 authentication. Affected file lib/silccore/silcauth.[ch].
4387 * Added `hash' field to the SilcIDListData structure. It is the
4388 hash negotiated in the SKE protocol. Affected file is
4391 * Slight redesigning of the SilcAuthPayload handling routines.
4392 Do not send SilcPKCS but SilcPublicKey as argument.
4394 * Implemented the public key authentication support to the
4395 serverconfig. The public key is loaded from the provided path
4396 and saved as authentication data to void * pointer. Thus,
4397 changed the unsigned char *auth_data to void *auth_data;
4399 * Fixed SHUTDOWN command to send the reply before the server
4400 is shutdown. :) Affected file silcd/command.c.
4402 * Fixed fatal bug in CONNECT command. The hostname was invalid
4403 memory and server crashed. Affected file silcd/command.c.
4405 * Fixed fatal bug in CLOSE command. The server_entry became
4406 invalid but was referenced later in the command. Affected file
4409 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Fixed fatal bug in failure packet handling. Server ignored
4412 the failure and thus crashed when it came.
4416 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4419 that the command may be executed only once in (about) 2 seconds.
4420 The old SILC_CF_LAG flag is same but allows command bursts up
4421 to five before limiting.
4423 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4424 server code. Various commands now includes the CF_LAG_STRICT
4425 flag to disallow any kind of miss-use of the command.
4427 * Fixed the silc_buffer_unformat to not to allocate any data
4428 if the length of the data is zero. It used to allocate the
4429 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4431 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Changed the format of AdminConnection configuration section
4434 in the server. Added username of the admin to the format.
4435 Affected files silcd/serverconfig.[ch].
4437 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4438 to return admin configuration data by host, username and/or
4441 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Implemented WHOWAS command to the server. Added the functions:
4445 silc_server_command_whowas_parse,
4446 silc_server_command_whowas_send_reply,
4447 silc_server_command_whowas_from_client and
4448 silc_server_command_whowas_from_server
4450 * Added <Client ID> argument to the WHOWAS command reply. Updated
4451 the protocol specs accordingly.
4453 * Implemented WHOWAS command and command_reply to the client
4456 Implemented the WHOWAS printing on the user interface.
4458 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added new argument to the WHOWAS command reply, the real name.
4461 It is an optional argument. Updated the protocol specs.
4463 * Added SilcIDCacheDestructor callback that is registered when
4464 the SilcIDCache is allocated. The callback is called when
4465 an cache entry in the ID Cache expires, or is purged from the
4466 cache. Added into lib/silccore/idcache.[ch].
4468 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4469 to destruct the client entries when the cache entry expires.
4470 Other ID Cache's in server and in the client library ignores
4473 * If the ID Cache entry's `expire' field is zero then the entry
4474 never expires. Added boolean `expire' argument to the
4475 silc_idcache_add function in the lib/silccore/idcache.[ch].
4476 If it is TRUE the default expiry value is used.
4478 * Added silc_server_free_client_data_timeout that is registered
4479 when client disconnects. By default for 5 minutes we preserve
4480 the client entry for history - for WHOWAS command.
4482 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Added support to the server to enforce that commands are not
4485 executed more than once in 2 seconds. If server receives
4486 commands from client more frequently, timeout is registered
4487 to process the commands. Affected file silcd/command.c.
4488 Added new function silc_server_command_process_timeout.
4490 * Changed NICK_NOTIFY handling in client library to check that
4491 if the client's nickname was changed, so there is no need to
4492 resolve anything from the server.
4494 * Removed error printing from the WHOIS and IDENTIFY commands.
4495 If error occurs then it is ignored silently in the client library.
4496 The application, however, may map the received error to
4497 human readable error string. The application currently maps
4498 the NO_SUCH_NICKNAME error to string.
4500 * Made the command status message public to the application. Moved
4501 them from lib/silcclient/command_reply.c to
4502 lib/silcclient/command_reply.h. The application can map the
4503 received command status to the string with the
4504 silc_client_command_status_message function.
4506 * Added check to the server to check that client's ID is same
4507 as the Source ID in the packet the client sent. They must
4510 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Added dist-bzip hook to the Makefile.am to make bzip2
4513 compressed distributions.
4515 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Server now enforces the maximum length for the nickname and
4518 the channel as protocol specification dictates. 128 bytes for
4519 nickname and 256 bytes for channel name.
4521 * Moved the WHOIS printing to the application. The client libary
4522 does not print out the WHOIS information anymore, the application
4523 must do it. Renamed silc_client_command_reply_whois_print to
4524 the silc_client_command_reply_whois_save.
4526 The client's idle time is also sent to the application now, and
4527 the idle is shown on screen.
4529 * Added silc_client_command_reply_identify_save to save the
4530 received IDENTIFY entries.
4532 * Do not check for channel private keys in message sending and
4533 reception if the channel does not have the PRIVKEY mode set.
4534 Affected file lib/silclient/client_channel.c.
4536 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4539 just surfaced after chaning the JOIN procedure.
4541 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4543 * Added silc_client_get_clients_by_list to get client entries
4544 from Client ID list, that is returned for example by JOIN
4545 and USERS command replies. The application should use this
4546 function for example when JOIN command reply is received to
4547 resolve the clients already on the channel (library does not
4548 do that anymore as USERS command reply is not used in the JOIN
4549 procedure anymore). Affected files lib/silcclient/silcapi.h and
4550 lib/silcclient/idlist.c.
4552 * JOIN command reply and USERS command reply returns now SilcBuffer
4553 pointers instead of unsigned char pointers when returning
4554 the client list and mode list.
4556 * Added <Client ID> argument to the JOIN command reply, mainly
4557 for the server to identify for which client the command was
4558 originally sent. Updated protocol specs accordingly.
4560 * Added SilcDlist private_key pointer to the SilcChannelEntry
4561 in the client to support the channel private keys. Affected
4562 file is lib/silcclient/idlist.h.
4564 * Added SilcChannelPrivateKey argument to the function
4565 silc_client_send_channel_message so that application can choose
4566 to use specific private ke if it wants to. If it is not provided,
4567 the normal channel key is used, unless private keys are set.
4568 In this case the first (key that was added first) is used
4569 as the encryption key.
4571 * Implemented the support for channel private key handling.
4572 Implemented the following functions:
4574 silc_client_add_channel_private_key,
4575 silc_client_del_channel_private_keys,
4576 silc_client_del_channel_private_key,
4577 silc_client_list_channel_private_keys and
4578 silc_client_free_channel_private_keys
4580 Affected file lib/silcclient/client_channel.c.
4582 * Added the support for the private keys in the channel message
4583 sending and encryption and in the message reception and
4584 decryption. Affected funtions are
4585 silc_client_send_channel_message and silc_client_channel_message.
4587 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Added SKE's key verify callback to the client library's
4590 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4592 * Removed the statement that server (or router) must send USERS
4593 command reply when joining to the channel so that the client
4594 knows who are on the channel. Instead, the client list and
4595 client's mode list is now sent in the JOIN command reply to the
4596 client who joined channel. This is better solution.
4598 * Added function silc_server_get_users_on_channel and function
4599 silc_server_save_users_on_channel to the silcd/server.[ch].
4601 * Removed function silc_server_command_send_users from the
4604 * Do not show topic on the client library anymore. The topic is
4605 sent in the command reply notify to the application and the
4606 application must show the topic now.
4608 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Added client searching by nickname hash into the IDENTIFY and
4611 WHOIS commands in the server as they were clearly missing from
4612 them. Affected file is silcd/command.c.
4614 * Fixed a bug in private message receiving in the client library.
4615 The remote ID was freed and it wasn't supposed, now it is
4618 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Minor fix to the channel payload; allocate the data area, as it
4621 needs to be of specific length.
4623 * If the key agreement port is zero then the operating
4624 system will define the bound port. Affected files are
4625 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4627 * Added new function silc_channel_payload_decrypt into the file
4628 lib/silccore/silcchannel.[ch].
4630 * Moved the channel message etc, check from silc_packet_decrypt
4631 to applications. The library calls now a generic
4632 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4633 when the packet is either normal or special. This was done to
4634 allow more wide range of checking that was not allowed when
4635 the code was in library. Now applications can do virtually any
4636 checks to the packet and return to the library the decision how
4637 the packet should be processed. Affected files are
4638 lib/silccore/silcpacket.[ch].
4640 Added silc_server_packet_decrypt_check to the server and
4641 silc_client_packet_decrypt_check to the client library.
4643 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4644 to send with specified source and destination information.
4646 * Channel message delivery between routers was broken after the
4647 channel key distribution was fixed earlier. The channel key
4648 was used be to distributed to other routers as well which is not
4649 allowed by the protocol. Now this is fixed and channel keys
4650 really are cell specific and the channel message delivery between
4651 routers comply with the protocol specification.
4653 * Fixed various commands in server to check also the global list
4654 for the channel entry and not just the local list. The affected
4655 file silcd/command.c.
4657 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * Added assert()s to buffer formatting and unformatting routines
4660 to assert (if --enable-debug) when error occurs. Affected
4661 file: lib/silcutil/silcbuffmt.c.
4663 * Changed to auto-reconnect to check whether the remote host is
4664 router and register the re-connect timeout if it is. It used
4665 to check that whether we are normal server, but router must do
4666 auto-reconnect with another router as well. Affected file
4669 * Removed the [<key len>] option from CMODE command as the cipher
4670 name decides the key length, nowadays. See the defined ciphers
4671 from the protocol specification.
4673 * Added [<hmac>] option to the CMODE command to define the HMAC
4674 for the channel. Added SILC_CMODE_HMAC channel mode.
4676 * Added [<hmac>] option for the JOIN command so that user can
4677 select which HMAC is used to compute the MACs of the channel
4680 * Added Hmac field to the Channel Message Payload. The integrity
4681 of plaintext channel messages are now protected by computing
4682 MAC of the message and attaching the MAC to the payload. The
4683 MAC is encrypted. Now, it is clear that this causes some
4684 overhead to the size of the packet but rationale for this is that
4685 now the receiver can verify whether the channel message decrypted
4686 correctly and also when private keys are set for the channel the
4687 receiver can decrypt the packet with several keys and check from
4688 the MAC which key decrypted the message correctly.
4690 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4691 lib/silccrypt/silccipher.[ch].
4693 * Added silc_hash_len to return the digest length into the
4694 lib/silcrypt/silchash.[ch].
4696 * Rewrote parts of Silc Channel Payload interface in the
4697 lib/silccore/silcchannel.[ch]. The encode function now also
4698 encrypts the packet and parse function decrypts it.
4700 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed a minor formatting bug in the SKE's key material processing.
4703 It actually might have processed the keys wrong way resulting
4706 * Redefined the mandatory HMAC algorithms and added new algorithms.
4707 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4708 and hmac-md5 truncated to 96 bits. The mandatory is now
4709 hmac-sha1-96. Rest are optional (including the one that used
4710 to be mandatory). Rationale for this is that the truncated HMAC
4711 length is sufficient from security point of view and can actually
4712 make the attack against the HMAC harder. Also, the truncated
4713 HMAC causes less overhead to the packets. See the RFC2104 for
4716 * Added new [hmac] configuration section. The SKE used to use
4717 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4718 is of course wrong. The official names that must be proposed in
4719 the SKE are the ones defined in the protocol specification
4720 (hmac-sha1-96 for example). The user can configure any hmac
4721 using any hash function configured in the [hash] section. At
4722 least, the mandatory must be configured.
4724 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4726 * Added HMAC list to the SKE proposal list. It has now both
4727 hash algorithm list and HMAC list. This makes the protocol
4728 incompatible with previous versions. The SKE now seems to work
4729 the way it is supposed to work, for the first time actually.
4731 * Defined plain Hash algorithms to the protocol specification.
4734 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Implemented support for key agreement packets into the server.
4737 Added functions silc_server_key_agreement and
4738 silc_server_send_key_agreement. Other than these functions,
4739 server has nothing to do with this packet.
4741 * Added support for private message key packets into the server.
4742 Added functions silc_server_private_message_key and
4743 silc_server_send_private_message_key.
4747 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4748 called in the protocol's final callback instead in the END
4749 protocol state. This makes a little more sense and in the same
4750 time in client we can use the same protocol routines for normal
4751 key exchange and to key agreement packet handling as well.
4753 * Added to both client's and server's KE protocol context the
4754 SilcSKEKeyMaterial pointer to save the key material. We will
4755 bring the key material to the protocol's final callback by doing
4756 this. The final callback must free the key material.
4758 * Added SKE's packet_send callback into client's KE protocol
4759 context so that the caller can choose what packet sending function
4760 is used. This way we can use different packet sending when
4761 doing normal SKE when doing key agreement packet handling (in
4762 the key agreement packet handling we do not want to encrypt
4765 * Implemented the responder side of the key agreement routines
4766 in the client. The client can now bind to specified port and
4767 accept incoming key negotiation. The key material is passed
4768 to the application after the protocol is over.
4770 * Implemented the processing of incoming Key Agreement packet
4771 in the client. Added function silc_client_key_agreement to
4774 * Implemented the intiator side of the key agreement routines
4775 in the client. The client can now initiate key agreement with
4776 another remote client. The key material is passed to the
4777 application after the protocol is over.
4779 * Created client_keyagr.c to include all the key agreement
4782 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4783 SILC_TASK_CALLBACK except that it is not static.
4785 * Created client_notify.c and moved the Notify packet handling
4786 from the client.[ch] into that file.
4788 * Created client_prvmsg.c and moved all private message and
4789 private message key routines from the client.[ch] into that file.
4791 * Create client_channel.c and moved all channel message and
4792 channel private key routines from the client.[ch] into that file.
4794 * Changed silc_client_get_client_by_id_resolve to resolve with
4795 WHOIS command instead of IDENTIFY command, in the file
4796 lib/silclient/idlist.c.
4798 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Implemented the SKE's responder side to the Client library.
4802 * When FAILURE is received to the protocol do not trust it
4803 blindly. Register a timeout to wait whether the remote closes
4804 the connection as it should do it, only after that process the
4805 actual failure. This was changed to both client and server.
4807 * Added client_internal.h to include some of the structures
4808 there instead of client.h in lib/silcclient/.
4810 * Added function silc_task_unregister_by_callback to unregister
4811 timeouts by the callback function.
4813 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Some "Incomplete WHOIS info" errors has been appearing on the
4816 log files. Took away the entry->userinfo check from WHOIS
4817 reply sending. The entry->userinfo is now " " if client did not
4818 provide one. I thought this was fixed earlier but something
4819 is wrong still. Let's see if the error still appears.
4821 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4823 * Fixed a minor bug in the login when the channel key is
4824 re-generated in the server. It used to generate the key in
4825 wrong order and thus caused problems in the channel traffic.
4827 * Fixed a minor bug in channel key distsribution after
4828 KICK command. The key was not sent to the router even though
4831 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Added silc_ske_process_key_material_data as generic routine
4834 to process any key material as the SILC protocol dictates. The
4835 function is used by the actual SKE library but can be used by
4836 applications as well. This relates to the private message keys
4837 and the channel private keys since they must be processed the
4838 same way the normal SILC session keys. The protocol dictates
4839 this. Affected files: lib/silcske/silcske.[ch].
4841 Added also silc_ske_free_key_material to free the
4842 SilcSKEKeyMaterial structure.
4844 * Defined silc_cipher_set_key function to set the key for
4845 cipher without using the object's method function. The affected
4846 files: lib/silccrypt/silccipher.[ch].
4848 * Implemented silc silc_client_add_private_message_key,
4849 silc_client_add_private_message_key_ske,
4850 silc_client_del_private_message_key,
4851 silc_client_list_private_message_keys and
4852 silc_client_free_private_message_keys functions in the
4855 Added functions silc_client_send_private_message_key to send
4856 the Private Message Key payload and silc_client_private_message_key
4857 to handle incoming Private Message Key payload.
4859 * Added Cipher field to the Private Message Key payload to set
4860 the cipher to be used. If ignored, the default cipher defined
4861 in the SILC protocol (aes-256-cbc) is used.
4863 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Removed lib/silcclient/ops.h file.
4867 Redefined parts of the SILC Client Library API. Created new
4868 file silcapi.h that deprecates the ops.h file and defines the
4869 published Client Library API. Defined also private message key
4870 API and channel private key API into the file.
4872 This is the file that the application must include from the
4873 SILC Client Library. Other files need not be included by
4874 the application anymore.
4876 * Added new key_agreement client operation callback and also
4877 defined the Key Agreement library API for the application.
4879 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4882 is used by clients to request key negotiation between another
4883 client in the SILC network. If the negotiation is started it
4884 is performed using the SKE protocol. The result of the
4885 negotiation, the secret key material, can be used for example
4886 as private message key.
4888 Implemented the Key Agreement payload into the files
4889 lib/silccore/silauth.[ch].
4891 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Redefined ciphers for the SILC protocol. Added some new ciphers
4894 and defined the key lengths for the algorithms. Changed the
4895 code accordingly. The default key length is now 256 bits.
4897 * Fixed SKE key distribution function silc_ske_process_key_material
4898 when the key length is more than 128 bits. The default key
4899 length in SILC is now 256 bits.
4901 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4902 to indicate unsupported algorithm.
4904 * Renamed rijndael.c to aes.c and all functions as well.
4906 * Fixed a long standing channel key setting bug in client library.
4907 Weird that it has never surfaced before.
4909 * Fixed bug in channel deletion. If the entire channel is removed
4910 then it must also delete the references of the channel entry
4911 from the client's channel list as the client's channel entry and
4912 the channel's client entry share same memory.
4914 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Implemented CONNECT and SHUTDOWN commands in the client.
4918 * Implemented CLOSE command to the client.
4920 * Added the function silc_idlist_find_server_by_name into the
4921 files silcd/idlist.[ch].
4923 Added the function silc_idlist_find_server_by_conn into the
4924 files silcd/idlist.[ch].
4926 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * DIE command was renamed to SHUTDOWN. Updated the both code
4931 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4932 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4934 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4937 * Added function silc_server_create_connection function to create
4938 connection to remote router. My server implementation actually
4939 does not allow router to connect to normal server (it expects
4940 that normal server always initiates the connection to the router)
4941 so the CONNECT command is only good for connecting to another
4944 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4946 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4947 or some other client was kicked from the channel.
4949 Implemented the handling of the notify type to both client
4952 Implemented silc_server_send_notify_kicked to send the KICKED
4953 notify. It is used to send it to the server's primary router.
4955 * Implemented the KICK command into server and client.
4957 * Added `query' argument to the silc_idlist_get_client function
4958 to indicate whether to query the client from server or not if
4961 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4962 to indicate that the client is not channel founder.
4966 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Removed the rng context from SilcPacketContext structure and
4969 changed that the packet routine uses the Global RNG API.
4971 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Added support for quit message that client can "leave" on the
4974 channel when it quits the SILC. It is ditributed inside the
4975 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4977 Added silc_server_free_client_data that will take the
4978 signoff message as argument.
4980 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4982 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Updated parts of the protocol specification to keep it up
4987 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4990 payloads in one packet.
4992 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4993 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4994 use now the new List flag.
4996 * Also deprecated the following packet types: REPLACE_ID,
4997 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4999 * Added list support for Notify packet in server.
5001 * Added silc_server_send_notify_channel_change to send the
5002 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5003 the silc_server_send_replace_id.
5005 * Added silc_server_send_notify_nick_change to send the
5006 NICK_CHANGE notify type. Deprecates the function
5007 silc_server_send_replace_id.
5009 * Added silc_server_send_notify_join to send the JOIN notify type.
5010 Deprecates the function silc_server_send_new_channel_user.
5012 * Added silc_server_send_notify_leave to send LEAVE notify type.
5013 Deprecates the function silc_server_send_remove_channel_user.
5015 * Added silc_server_send_notify_cmode and
5016 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5017 types. Deprecates the silc_server_send_set_mode function.
5019 * Added SERVER_SIGNOFF notify type to indicate that server has
5020 quit. This means that all clients on the channel from that
5021 server will drop. This can be also used when netsplit happens.
5023 Deprecated REMOVE_ID packet type since it is not needed anymore
5026 Added silc_server_send_notify_server_signoff to send the
5027 SERVER_SIGNOFF notify type. Deprecates the function
5028 silc_server_send_remove_id.
5030 Added also silc_server_send_notify_signoff to send the
5031 SIGNOFF notify type.
5033 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5034 SILC protocol from this day on. Changed the protocol
5035 specification as well.
5037 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5038 notify type. It is used between routers to notify about
5039 topic changes on a channel.
5041 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5044 * Partly updated the protocol specification to comply with the
5045 changes now made. It is still though a bit outdated.
5047 * The JOIN notify type now takes one extra argument <Channel ID>.
5048 The packet used to be destined to the channel but now the
5049 JOIN type may be sent as list thus it is impossible to
5050 destine it to any specific channel. By adding this argument
5051 it is again possible.
5053 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Added CREDITS file. The CHANGES and CREDITS file will appear
5056 in the distribution as well.
5058 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5061 types in the server's silcd/packet_receive.c.
5063 * Implemented CMODE and CUMODE to work in router environment.
5065 * Fixed minor encoding and decoding buglet from the
5066 lib/silccore/silcmode.c.
5068 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5071 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5073 * Changed all SilcConfigServer* and silc_config_server* to
5074 SilcServerConfig* and silc_server_config*, respectively.
5077 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Associated the ID (client or server ID) to the Authentication
5080 Payload to avoid any possibility of forging. Updated the
5081 protocol specification and the code accordingly.
5083 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * The RSA key length is now save to the RsaKey context in the
5086 key generation process in lib/silccrypt/rsa.c. The key length
5087 is now used to figure out the maximum size of the block allowed
5088 to be encrypted/signed.
5090 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5091 is equivalent to the silc_mp_mp2bin but does not allocate any
5094 * Changed silc_mp_mp2bin API to take length argument. If it is
5095 non-zero then the buffer is allocated that large. If zero, then
5096 the size is approximated using silc_mp_sizeinbase, which however
5099 * Created Global RNG API which is global RNG that application can
5100 initialize. After initializing, any routine anywhere in the
5101 code (including library) can use RNG without allocating a new
5102 RNG object. This was done to allow this sort of use of the
5103 RNG in code that has no chance to allocate RNG object. All
5104 applications currently allocate this and many routines in the
5105 library use this. Affected file lib/silccrypt/silcrng.[ch].
5107 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5108 it to use the Global RNG API.
5110 * Defined Authentication Payload into protocol specification that
5111 is used during SILC session to authenticate entities. It is
5112 used for example by client to authenticate itself to the server
5113 to obtain server operator privileges.
5115 Implemented this payload into the lib/silccore/silcauth.[ch].
5116 Implemented also routines for public key based authentication
5117 as the new protocol specification dictates.
5119 Moved definitions of different authentication methods from
5120 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5122 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5123 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5124 silc_pkcs_verify_with_hash functions into the file
5125 lib/silccrypt/silcpkcs.[ch].
5127 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * The client entry's userinfo pointer must be always valid.
5130 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5131 will fail since it requires the userinfo. Now, the userinfo
5132 is allocated as "" if actual userinfo does not exist. Actually,
5133 it must exist and it is totally Ok to drop client connections
5134 that does not announce the userinfo. However, we will make
5135 this workaround for now.
5137 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5138 to return the remote port by socket.
5140 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5143 SILC_SERVER_PENDING_EXEC and added an new macro
5144 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5145 data or when error occurs while processing the pending command.
5147 Added new argument `destructor' into silc_server_command_pending
5148 and to the SilcServerCommandPending object. This destructor is
5149 now called after calling the pending callback or if error occurs
5150 immediately. If error occurs the actual pending callback won't
5151 be called at all - only the destructor. The destructor may be
5152 NULL if destructor is not needed.
5154 All this applies for client library code as well. Similar
5155 changes were made there as well for the pending commands.
5157 In the client, the application must now allocate the
5158 SilcClientCommandContext with the silc_client_command_alloc
5161 * Added reference counter to the SilcServerCommandContext. Added
5162 function silc_server_command_alloc and silc_server_command_dup
5165 Same type of functions added to the client library for the same
5168 * Removed the cmd_ident from IDListData away since it is now
5169 global for all connections. It is the command identifier used
5170 in command sending and with pending commands. The affected file
5173 * Added reference counter to the SilcSocketConnection objecet to
5174 indicate the usage count of the object. The object won't be
5175 freed untill the reference counter hits zero. Currently only
5176 server uses this, and client ignores it. The client must be
5177 set to use this too later. The affected files are
5178 lib/silccore/silcsockconn.[ch]. Added also the function
5179 silc_socket_dup to increase the reference counter.
5181 This was mainly added because it is possible that the socket
5182 is removed underneath of pending command or other async
5183 operation. Now it won't be free'd and proper DISCONNECTING
5184 flags, etc. can be set to avoid sending data to connection that
5185 is not valid anymore.
5187 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5188 the connection. After that it sets SILC_SET_DISCONNECTED.
5189 It is, however, possible that the socket data is not still freed.
5190 The silc_server_packet_process now checks that data is not
5191 read or written to connection that is DISCONNECTED. The socket
5192 get's freed when the reference counter hits zero.
5194 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Changed the client operation API: channel_message operation's
5197 `sender' is now the client entry of the sender, not the nickname
5198 and the `channel' is the channel entry, not the channel name.
5200 In the private_message operation the `sender' is now also the
5201 client entry of the sender not the nickname.
5203 Affected file is lib/silcclient/ops.h and all applications
5204 using the client operations.
5206 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Moved the calling of ops->connect() from connect_to_server_final
5209 into receive_new_id functin since that is the point when the
5210 client is actually allowed to send traffic to network. The
5211 affected file is lib/silcclient/client.c.
5213 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5216 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5217 (if needs broadcasting) instead of broadcasting the packets one
5218 by one which would make a burst in the network traffic.
5220 * Added `broadcast' argument to the functions in silcd/server.[ch]
5221 silc_server_create_new_channel[_with_id] to indicate whether
5222 to send New Channel packet to primary router.
5224 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5226 * Added new function into the silcd/server.[ch] files:
5227 silc_server_create_new_channel_with_id to create new channel with
5228 already existing Channel ID.
5230 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5231 lib/silccore/silcpacket.h. This packet is used t send list of
5232 Set Mode payloads inside one packet. Server uses this to set
5233 the modes for the channels and clients on those channels, that it
5234 announced to the router when it connected to it. The protocol
5235 specification has been updated accordingly.
5237 * The silc_server_new_channel did not handle the packet coming
5238 from normal server as it normally does not send that. However,
5239 when it announces its channels it does send it. Implemented
5240 the support for that.
5242 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5243 into the file lib/silccore/id.h.
5245 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Fixed memory leaks in the functions silc_idlist_del_client,
5248 silc_idlist_del_channel and silc_idlist_del_server in the file
5249 silcd/idlist.c. All of those leaked like a sieve.
5251 * Fixed some small memory leaks in the client's function
5252 silc_client_notify_by_server.
5254 * Added functions into silcd/server.c: silc_server_announce_clients,
5255 silc_server_announce_channels and silc_server_announce_server.
5256 These functions are used by normal and router server to announce
5257 to its primary router about clients, channels and servers (when
5258 router) that we own. This is done after we've connected to the
5261 These functions effectively implements the following packet types:
5262 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5263 and SILC_PACKET_NEW_ID_LIST.
5265 * Added new functions into the silcd/packet_receive.[ch]:
5266 silc_server_new_id_list, silc_server_new_channel_list and
5267 silc_server_new_channel_user_list to handle the incoming
5268 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5270 * Added support of changing Channel ID in the function
5271 silc_server_replace_id. If the server that announces a channel
5272 to the router already exists in the router (with same name but
5273 with different Channel ID), router is responsible to send
5274 Replace ID packet to the server and force the server to change
5275 the Channel ID to the one router has.
5277 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5278 client that the Channel ID has been changed by the router. The
5279 normal server sends this to the client. Client must start using
5280 the new Channel ID as the channel's ID.
5282 Implemented handling of this new type into lib/silcclient/client.c
5283 into the function silc_client_notify_by_server.
5285 * Added new function silc_idlist_replace_channel_id into the files
5286 silcd/idlist.[ch] to replace the Channel ID.
5288 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Call silc_server_command_identify_check always when processing
5291 the IDENTIFY command in silcd/command.c
5293 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5296 send keepalive packets. The packet can be sent by clients,
5297 servers and routers.
5299 Added function silc_socket_set_heartbeat into the file
5300 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5301 If not set, the heartbeat is not performed. The actual
5302 heartbeat is implemented in the low level socket connection
5303 library. However, application is responsible of actually
5306 Added silc_server_send_heartbeat to send the actual heartbeat
5307 packet into silcd/packet_send.[ch]. Server now performs
5308 keepalive with all connections.
5310 * Added silc_task_get_first function into lib/silcutil/silctask.c
5311 to return the timeout task with shortest timeout. There was a bug
5312 in task unregistration that caused problems. TODO has been
5313 updated to include that task system must be rewritten.
5315 * The client library will now resolve the client information when
5316 receiving JOIN notify from server for client that we know but
5317 have incomplete information.
5319 * Rewrote parts of silc_server_remove_from_channels and
5320 silc_server_remove_from_one_channel as they did not remove the
5321 channel in some circumstances even though they should've.
5323 * Encryption problem encountered in server:
5325 The LEAVE command used to send the Channel Key packet to the
5326 router immediately after generating it. However, the code
5327 had earlier sent Remove Channel user packet but not immediately,
5328 ie. it was put to queue. The order of packets in the router
5329 was that Channel Key packet was first and Remove Channel User
5330 packet was second, even though they were encrypted in the
5331 reverse order. For this reason, MAC check failed. Now, this
5332 is fixed by not sending the Channel Key packet immediately but
5333 putting it to queue. However, this is more fundamental problem:
5334 packets that are in queue should actually not be encrypted
5335 because packets that are sent immediately gets encrypted
5336 actually with wrong IV (and thus MAC check fails). So, packets
5337 that are in queue should be encrypted when they are sent to
5338 the wire and not when they put to the queue.
5340 However, the problem is that the current system has not been
5341 designed to work that way. Instead, the packet is encrypted
5342 as soon as possible and left to the queue. The queue is then
5343 just purged into wire. There won't be any fixes for this
5344 any time soon. So, the current semantic for packet sending
5347 o If you send packet to remote host and do not force the send
5348 (the packet will be in queue) then all subsequent packets to the
5349 same remote host must also be put to the queue. Only after the
5350 queue has been purged is it safe again to force the packet
5353 o If you send all packets immediately then it safe to send
5354 any of subsequent packets through the queue, however, after
5355 the first packet is put to queue then any subsequent packets
5356 must also be put to the queue.
5358 Follow these rules and everything works fine.
5360 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5362 * Added new function silc_server_remove_clients_by_server to
5363 remove all client entries from ID list when the server connection
5364 is lost. In this case it is also important to invalidate all
5365 client entires as they hold the invalid server entry. This
5366 fixes fatal bug when server has lost connection and will reconnect
5369 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Made some sanity checks to silc_server_daemonise like to check
5372 whether the requested user and group actually exists.
5374 * Added sanity check to SKE's silc_ske_responder_finish to check
5375 that the public and private key actually is valid.
5377 * Invalidate the client's nickname when receiving Replace ID
5378 packet and the Client ID is being replaced. This means that the
5379 server will query the nickname if someone needs it (client)
5382 * Sort the ID Cache in client library when the ID Cache data
5383 has changed (needs sorting).
5385 * Do not allow for SILC client to create several connections to
5386 several servers. The client does not support windows right now
5387 and generating multiple connections causes weird behaviour.
5389 Irssi-silc client does support windows and can handle several
5390 connections without problems, see: www.irssi.org and SILC plugin.
5392 * Fixed some places where client was added to the IDList. The
5393 rule of thumb is following (in order to get everything right):
5394 If the client is directly connected local client then the
5395 `connection' argument must be set and `router' argument must be
5396 NULL to silc_idlist_add_client function. If the client is not
5397 directly connected client then the `router' argument must
5398 bet set and the `connection' argument must be NULL to the
5399 silc_idlist_add_client function.
5401 * The funtion silc_server_packet_send_local_channel actually did
5402 not check whether the client was locally connected or not. It
5403 does that now. Fixed a bug related to LEAVE command.
5405 * Fixed Remove Channel User payload parsing bug in server's
5406 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5408 * The server's silc_server_save_channel_key now checks also the
5409 global ID list for the channel as it might not be in the local
5410 list. Fixed a bug related to LEAVE command.
5412 * Is this the end of the [<unknown>] buglet that has been lurking
5413 around for a long time? A little for loop fix in server's
5414 silc_server_command_whois_parse that is used by both IDENTIFY
5415 and WHOIS command. At least, this was a clear bug and a cause
5416 of one type of [<unknown>] buglet.
5418 * WHOIS and IDENTIFY commands call the function
5419 silc_server_command_[whois/identify]_check function even if
5420 we are not router server.
5422 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * Added --with-gmp configuration option. If set the GMP
5425 is always compiled in the SILC source tree. If not set then
5426 it is checked whether the system has the GMP3 installed. If
5427 it has then the GMP won't be compiled (the system's headers
5428 and library is used), if it doesn't have it then the GMP is
5429 compiled in the SILC source tree.
5431 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Changed RSA private exponent generation to what PKCS #1
5434 suggests. We try to find the smallest possible d by doing
5435 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5436 not security fix but optimization.
5438 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Added new config entry [Identity] to fork the server and run
5441 it as specific user and group. A patch from Bostik.
5443 * Imported Dotconf configuration library into lib/dotconf.
5444 This will be used to create the SILC configuration files later.
5445 It will appear in the distsribution after this commit.
5447 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * A big code auditing weekend happening. Auditing code for
5450 obvious mistakes, bugs and errors. Also, removing any code
5453 Removed files for being obsolete:
5455 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5456 inline in the file lib/silcutil/silcbuffer.h)
5458 o lib/silcutil/silcbufutil.c (the header has inline versions)
5460 Changed code to fix possible error conditions:
5462 o The buffer formatting routines now check that the destination
5463 buffer really has enough space to add the data. This applies for
5464 both buffer formatting and unformatting
5465 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5466 unformatting was changed to accomodate following rules:
5467 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5468 sent to the function while XXX_*STRING will not allocate or copy
5469 the data into the buffer. Instead it sets the pointer from the
5470 buffer into the pointer sent as argument (XXX_*STRING used to
5471 require that the pointer must be allocated already). This change
5472 makes this whole thing a bit more consistent and more optimized
5473 (note that the data returned in the unformatting with XXX_*STRING
5474 must not be freed now). The routines return now -1 on error.
5476 o Tried to find all code that use buffer_format and buffer_unformat
5477 and added return value checking to prevent formatting and
5478 especially unformatting errors and possible subsequent fatal
5481 o Changed ske->x and ske->KEY to mallocated pointers in
5482 lib/silcske/silcske.h. Fixed possible data and memory leak.
5484 o Added return value checking to all *_parse* functions. Fixed
5485 many memory leaks as well.
5487 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5488 so that buffer overflows would not happen. All code now also
5489 checks the return value as it can fail.
5491 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added reconnection support to server if the normal server looses
5494 its connection to the router (for example if router is rebooted).
5495 The server performs normal reconnection strategy implemented
5496 to the server. Affected file silcd/server.c.
5498 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added new packet type SILC_PACKET_SET_MODE that is used to
5501 distribute the information about changed modes (for clients,
5502 channels and clients channel modes) to all routers in the
5503 network. Updated the protocol specification accordingly.
5505 Added functions into silcd/packet_send.c and
5506 silcd/packet_receive.c: silc_server_send_set_mode,
5507 silc_server_set_mode.
5509 Added new files silcmode.[ch] into lib/silccore that implements
5510 the encoding and decoding of Set Mode Payload. Added new type
5511 SilcSetModePayload. Moved the definitions of different modes
5512 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5514 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Oops, a little mistake in server's connection authentication
5517 protocol. The protocol is not ended with FAILURE but with
5518 SUCCESS if the authentication is Ok. :) Affected file is
5521 * Implemented NICK_CHANGE notify handling in server in the file
5522 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5523 the local clients on the channel. After the changing nickname
5524 in router environment snhould work and the [<unknown>] nickname
5525 should appear no more.
5527 The silc_server_replace_id function that receives the Replace ID
5528 payload now sends the NICK_CHANGE notify type also in the file
5529 silcd/packet_receive.c
5531 * Changed WHOIS and IDENTIFY command to support the maximum amount
5532 of arguments defined in protocol specs (3328 arguments). This
5533 fixed a bug that caused problems when there were more than three
5536 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added extra parameter, command identifier, to the
5539 silc_client_send_command so that explicit command identifier
5542 Changed that ID list routines uses specific command identifier
5543 when sending WHOIS/IDENTIFY requests to the server so that they
5544 can be identified when the reply comes back.
5546 Affected files lib/silcclient/command.[ch],
5547 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5549 * Added `sender' argument to silc_server_packet_send_to_channel
5550 to indicaet the sender who originally sent the packet to us
5551 that we are now re-sending. Ignored if NULL. Affected file
5552 silcd/packet_send.[ch].
5554 * Added some server statistics support in silcd/server_internal.h
5555 SilcServerStatistics structure and around the server code. Also
5556 send some nice statistics information when client is connecting
5559 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Fixed channel ID decoding in server's JOIN command reply in
5562 silcd/command_reply.c
5564 * Fixed braodcasting of replace ID payload to not to send it if
5565 we are standalone server in silcd/packet_receive.c.
5567 * Fixed all channel message sending routines to not to send
5568 packets to clients that has router set, since they are routed
5569 separately in the same function earlier. Affects file
5570 silcd/packet_send.c and all channel packet sending functions.
5572 * In USERS reply, res_argv[i] are not allocated, the table
5573 is allocated. Thus changed that free the table, not its
5576 * In server's whois_check and identify_check if the client is
5577 locally connected do not send any WHOIS commands - they are not
5580 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Fixed some minor bugs in client when sending WHOIS command. The
5583 arguments was in wrong order.
5585 * Removed statis function add_to_channel from server in
5586 silcd/command.c that was previously used with the joining but
5589 * Tested USERS command in router environment successfully with two
5590 routers, two servers and two clients.
5592 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Reorganized the USERS command and command reply in client library
5595 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5596 When the command is given by user we register a pending command
5597 callback that will reprocess the command after the reply has been
5598 received from the server. When reprocessing the packet we then
5599 display the information. Thus, the USERS information is displayed
5600 now in the command callback instead of in the command reply
5601 callback. The processing of the command is same as previously
5602 when server has sent the command reply in the JOINing process.
5604 * Added to USERS command in silcd/command_reply.c to join the client,
5605 we didn't use to know about, to the channel after we've created
5606 a client entry for it. Also, for clienet we did know already still
5607 check whether it is on the channel or not and add it if not.
5609 * Removed silc_server_command_join_notify as the function and its
5612 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Changed the client's pending command handling to the same as the
5615 server's pending command handling. It is also now possible to
5616 execute command reply functions from other command reply
5617 function as the function callbacks for commands and command
5618 replies are one and same. The pending commands are not static
5619 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5620 in client connection context. Thus, pending commands are server
5621 connection specific as it is convenient.
5623 Changed the function silc_client_command_pending and
5624 silc_client_command_pending_del and added new function
5625 silc_client_command_pending_check. Removed the
5626 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5629 * Added cmd_ident, current command identifier, to the client
5630 connection context in lib/silcclient/client.h to keep track on
5631 command identifiers used in command sending. Client's command reply
5632 function handling now supports the mandatory command identifiers.
5634 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5635 funtions in client to fully support pending command callbacks.
5637 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5638 as one of the arguments to the application in the command reply
5641 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5642 before first releasing SILC but came back. Now it is removed again
5643 and should come back nomore. The FORWARDED flag was used only
5644 by the JOINing procedure by forwarding the command packet to router.
5645 Now, the JOINing procedure has been changed to more generic (due
5646 to various router environment issues) and FORWARDED is not needed
5647 anymore for anything. The protocol specification is yet to be
5650 Now, removed silc_server_packet_forward from server and the flag
5651 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5653 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Renamed NAMES command to USERS command. The NAMES was named that
5656 due to historical reasons. Now it is renamed. Also, rewrote
5657 parts of the USERS command. The nickname list is not sent anymore
5658 by the server. Only Client ID and mode lists are sent in the USERS
5659 command. Changed this also to the protocol specification.
5661 The client now resolves the names and stuff after it receives
5662 the USERS list from the server when joining to the channel.
5664 * WHOIS and IDENTIFY commands has been changed to support multiple
5665 Client ID's per command. One can now search for multiple users
5666 in the network by sending only one WHOIS or IDENTIFY command.
5667 Changed the code and the protocol specifications.
5669 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5670 uses silc_server_command_whois_parse to parse the request. */
5672 * If normal server, do not parse the WHOIS and IDENTIFY requests
5673 before sending it to the router. Saves some time.
5675 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Fixed JOIN command on client library. Wrong number of arguments
5678 used to crash the client.
5680 * Added silc_server_channel_has_global function to check whether
5681 channel has global users or not.
5683 * Added silc_server_channel_has_local function to check whether channel
5684 has locally connected clients on the channel.
5686 * The silc_server_remove_from_one_channel now checks whether the
5687 channel has global users or not after given client was removed from
5688 the channel. It also checks whether the channel has local clients
5689 on the channel anymore. If it does not have then the channel entry
5690 is removed as it is not needed anymore.
5692 * The silc_server_notify now checks on JOIN notify whether the joining
5693 client is one of locally connected or global. If it is global then
5694 the channel has now global users on the channel and that is marked
5695 to the channel entry. Also, it now saves the global client to
5696 global list who is joining and JOINs it to the channel. This is
5697 for normal server, that is.
5699 Changed silc_server_send_notify_on_channel,
5700 silc_server_packet_relay_to_channel and
5701 silc_server_packet_send_to_channel check if we are normal server
5702 and client has router set (ie. global client) do not send the
5703 message to that client, as it is already routed to our router.
5705 * Implemented LEAVE notify type handling in silc_server_notify
5708 * Tested LEAVE command in router environment successfully. Tested
5709 with two routers, two servers and two clients.
5713 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5715 * Implemented SIGNOFF notify type handling in silc_server_notify
5718 * silc_server_remove_id now removes the client entry from all channels
5719 it has joined and thusly sends SIGNOFF notify type.
5721 * Rewrote the NAMES list generation in server by removing two excess
5722 loops. The lists are created now inside one loop.
5724 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * silc_server_remove_channel_user checks now also global list
5727 for channel and client.
5729 * silc_server_new_channel_user checks now both local and global
5730 list for channel and client. Fixed a bug in client id decoding.
5731 Used to decode wrong buffer.
5733 * silc_server_channel_message checks now both local and global
5734 list for channel entry.
5736 * Tested channel joining (hence JOIN) in router environment
5737 successfully. Tested with two routers, two servers and two
5740 * Tested channel message sending in router environment successfully.
5742 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Added silc_server_save_channel_key into server.[ch] to save the
5745 received channel key in Channel Key payload processing. It is
5746 also used in JOIN command reply handling.
5748 Equivalent function silc_client_save_channel_key added into
5749 client.[ch] into client library.
5751 * Changed JOIN command reply to send information whether the channel
5752 was created or not (is existing already) and the channel key
5753 payload. Changed protocol specs accordingly.
5755 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5756 the request was sent by ID and not by nickname. Crashed on
5759 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5762 now correctly save the received data.
5764 * silc_server_free_sock_user_data now notifies routers in the
5765 network about entities leaving the network.
5767 At the same time implemented functions silc_server_remove_id
5768 and silc_server_send_remove_id to receive and send REMOVE_ID
5769 packets. The packet is used to notify routers in the network
5770 about leaving entities. The ID removed will become invalid in
5773 * Added function silc_idlist_del_server into server. Removes and
5774 free's server entry from ID list.
5776 * silc_server_private_message function now checks, if we are router,
5777 that the destination ID really is valid ID, naturally.
5779 * In router when NEW_ID packet is received (for new client) the
5780 hash of the Client ID is saved in the ID Cache but the
5781 client->nickname is set to NULL, instead of putting the hash
5784 IDENTIFY command now also checks that client->nickname must be
5785 valid. If it is not if will request the data from the server who
5786 owns the client. Added new function
5787 silc_server_command_identify_check.
5789 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5790 to set the command to already allocated Command Payload.
5792 * Tested private message sending in router environment with two
5793 routers, two servers and two clients. Fixed minor bugs and now
5796 * Fixed segfault from client's NAMES command. Used to crash if
5799 * Forwarded packets must not be routed even if it is not destined
5800 to the receiver. Changed server code comply with this.
5802 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Added `require_reverse_mapping' boolean value to ServerParams
5805 structure. If TRUE (not default) the server will require that
5806 the connecting host has fully qualified domain name.
5808 If the reverse mapping is not required and hostname could not be
5809 found the IP address is used as hostname.
5811 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * Implemented version string checking to both client and server.
5814 The check is incomplete currently due to the abnormal version
5815 strings used in development version of SILC.
5817 * Changed all command functions in server to use the new
5820 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Changed char *data to unsigned char *data in ID Cache system to
5823 support binary data as ID Cache data. Changed code to support
5824 binary data in lib/silccore/idcache.c.
5826 * Renamed silc_server_packet_relay_command_reply to
5827 silc_server_command_reply as it is normal packet receiving
5828 function. Rewrote the function to accept command replys for
5829 servers and not only for clients.
5831 * Mark remote router always as registered server if we are connecting
5832 to it. Otherwise, commands sent by the router to us are ignored.
5834 * All ID List find routines now returns the ID Cache Entry pointer
5835 as well if requested.
5837 * WHOIS command works now in router environment, tested with two
5838 routers, two servers and two clients.
5840 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5841 in router environment (as it is almost equivalent to WHOIS) but
5842 hasn't been tested thoroughly. Added new functions:
5844 silc_server_command_identify_parse
5845 silc_server_command_identify_send_reply
5846 silc_server_command_identify_from_client
5847 silc_server_command_identify_from_server
5849 * Disabled route cache adding because adding two different ID's with
5850 same IP replaces the old cache entry thus giving wrong route.
5851 The entry->router->connection is always the fastest route anyway
5852 so route cache may not be needed. Of course, new routes maybe
5853 established after receiving the ID when the entry->router->connection
5854 might not be anymore the most optimal.
5856 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Add route cache for received ID for fast routing.
5860 * Added silc_server_packet_route to route received packet on router
5861 that is not destined to us.
5863 * Renamed silc_server_get_route to silc_server_route_get.
5865 * Added id_string and id_string_len fields into SilcServer to
5866 include encoded ServerID for fast comparing without excess
5867 encoding of the ID's.
5869 * Cleaned up WHOIS command on server side. Added following static
5872 silc_server_command_whois_parse
5873 silc_server_command_whois_check
5874 silc_server_command_whois_send_reply
5875 silc_server_command_whois_from_client
5876 silc_server_command_whois_from_server
5878 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5879 arguments in command replies. All command functions should be
5880 updated to use this macro.
5882 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Minor typo fixes on command reply handling on server.
5886 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Added silc_server_command_add_to_channel internal routine to add
5889 the client to the channel after router has created the channel and
5890 sent command reply to the server.
5892 * Added generic silc_server_send_command to send any command from
5895 * Use static buffer with ID rendering instead of duplicating data.
5897 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Fixed a channel user mode bug when joining to a channel server gave
5900 everybody channel founder rights, oops.
5902 * We mark ourselves as the router of the incoming server connection
5903 if we are router ourselves. This way we can check in some packet
5904 sending functions whether it is locally connected server. For
5905 incoming router connections we put NULL.
5907 * For router sending packets locally means now always sending the
5908 packet cell wide; to local clients and local servers. For normal
5909 server sending packet locally means sending it to only local
5912 * Fixed the JOIN command to really work in router environment. If the
5913 channel is created it is always created by the router. Router is
5914 also responsible of making the initial joining to the channel,
5915 sending JOIN notify to the sending server and distributing
5916 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5917 does not exist server doesn't do anything else but forward the
5918 command to the router which performs everything.
5920 * Added silc_server_send_channel_key function to send the Channel Key
5923 * Added silc_server_create_channel_key to create new channel key. The
5924 channel key is now re-generated everytime someone joins or leaves
5925 a channel, as protocol dictates. Note: channel->key_len is the
5928 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5931 packet_receive.[ch] to separate packet sending and receiving
5932 routines. The server.[ch] now includes everything else including
5933 actual packet processing (writing and reading data) and other
5936 Renamed silc_server_private_message_send_internal to
5937 silc_server_send_private_message. The routine is still though
5938 used only to relay private messages as server does not send
5939 private messages itself.
5941 Renamed silc_server_new_channel to silc_server_create_new_channel
5942 and added new function sicl_server_new_channel that handles the
5943 incoming New Channel packet. Added also new sending function
5944 silc_server_send_new_channel to send New Channel Payload.
5946 * Added new function silc_server_notify to process incoming notify
5947 packet to the server/router. Server may then relay the notify
5948 to clients if needed.
5950 * Added new function silc_server_new_channel_user to process incoming
5951 New Channel User packet. Router will redistribute the packet and
5952 send JOIN notify to its local clients and locally connected servers
5953 if needed. Normal server will send JOIN notify to its local client
5954 on same channel when received this packet. Added also corresponding
5955 sending function silc_server_send_new_channel_user to sent the
5958 * Added boolean route argument to send_notif_to_channel and
5959 packet_send_to_channel functions to attempt to route the packet
5960 if it is TRUE and send only locally if it is FALSE.
5962 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * silc_server_replace_id now broadcasts the received replace ID
5965 packet if it is not broadcast packet already. The router must
5966 broadcast to inform other routers about changed ID.
5968 * Added backpointer to server's router into SilcServer context in
5969 silcd/server_internal.h.
5971 * Fixed silc_server_packet_broadcast to send correct broadcast
5974 * The channel key is now distributed to the local client as soon
5975 as it is received from the router (in router environment) so that
5976 no other packet may be sent for the channel until client has
5979 * silc_server_remove_channel_user now broadcasts the received
5980 Remove Channel User packet if it is not broadcast packet already.
5981 The router must broadcast to inform other routers about removed
5984 * Added users field into SilcPacketContext that is a reference count
5985 of the context. One can increase the reference count by calling
5986 silc_packet_context_dup which is now changed to just increase the
5987 reference count instead of duplicating the data. The reference
5988 count is decresed by calling silc_packet_context_free that will
5989 free the data after the reference count hits zero.
5991 For now on the packet context and everything allocated into it
5992 (including the raw packet from network) must be freed by calling
5993 the new silc_packet_context_free function. Added also new function
5994 silc_packet_context_alloc that must be used now to allocate the
5995 context. This also means that if a routine is asynchronous from
5996 silc_[client/server]_packet_parse_type the packet context must
5997 be duplicated by calling silc_packet_context_dup. Otherwise it
5998 gets free'd after silc_[client/server]_packet_parse_type returns.
5999 Also, one must remember that if packet is duplicated then its
6000 reference count must be decresed by calling the free function as
6001 many times as it was duplicated.
6003 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6004 from both client and server.
6006 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Made joining to a channel working in router environment.
6010 * Cleaned up JOIN command on server side and create function
6011 silc_server_command_join_channel internal routine to make the
6014 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Changed silc_command_pending list to SilcDList. Also, added
6017 `ident' field to SilcServerCommandPending structure to identify
6018 the reply and to call correct callback.
6020 Added silc_server_command_pending_check function to replace the
6021 corresnponding macro. The silc_command_pending list is not
6024 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6025 to set identifier to previously allocated Command Payload. It
6026 is used to set identifier for command when resending Command
6029 * Added silc_command_payload_encode_payload to encode Command
6030 Payload buffer from SilcCommandPayload structure.
6032 * Added silc_argument_payload_encode_payload to encode Argument
6033 payload buffer from SilcArgumentPayload structure.
6035 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Changed WHOIS command to support router connection on server side.
6038 The whois request is always sent to router unless the server is
6039 standalone server. After server has received the reply from the
6040 router will it send the reply to the client.
6042 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6043 broadcast received broadcast packet. The function is used only
6044 by router. The broadcast packet is always sent to the router's
6047 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6048 render given ID to printable string, for log files for example.
6050 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Made basic router to router connections working. At least they
6053 can now connect to each other but nothing really works the way
6054 they are supposed - yet.
6056 * Added new initiator token to RouterConnection configuration
6057 file in silcd/serverconfig.[ch]. It is used to tell whether we
6058 are the initiator to the remote router or whether we'll expect
6059 the other end to connect.
6061 * Moved registering of listener task to silc_server_init, hence
6062 the server starts listenning as soon as it is run, even if it
6063 does not have connections to other routers. Let's see how well
6066 * Changed default connection retry timeouts for more suitable in
6069 * Removed cipher and such arguments from silc_idlist_add_client
6070 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6071 Added new function silc_idlist_add_data to add the keys and stuff
6074 * Added SilcIDListData structure and added it to SilcClientEntry
6075 and SilcServerEntry as their first field in the structure. This
6076 way we can explicitly cast the ID entries to the SilcIDListData
6077 structure and get common data for the entries. In past, we had
6078 to first check what type of connection it is and then cast it to
6079 correct ID entry type. Now, we can directly cast the opaque
6080 pointer to the SilcIDListData (no matter what ID entry it actually
6081 is) and get the data needed.
6083 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6086 in some circumstances even if threre were timeout tasks, though not
6087 IO tasks, but tasks anyway. Now fixed.
6089 * Defined SilcServerConnection structure to hold connection specific
6090 stuff about directly connected servers and routers. The definition
6091 is currently in silcd/server_internal.h. I thought about having
6092 a bit more important role fro this struct but for now it is used
6093 only when connecting to other server (or router actually).
6095 * Added connecting retry support in server when connecting to
6096 router(s). The retry feature implement exponential backoff
6097 algorithm. Also, added SilcServerParams structure to hold default
6098 parameters for server. For now, it include these retry settings
6099 and are hard coded. After server is moded to be as Silc Server
6100 Library this structure will be more important.
6102 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Changed client librarys channel->clients table to SilcList and
6105 changed code accordingly.
6107 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * Changed client's channel table to SilcList and changed code
6110 accordingly. Also changed SilcChannelClientEntry to include back-
6111 pointer to the channel so that client entry can use that structure
6112 as list as well and we have fast cross-reference to the channel.
6113 This change dramatically decreased the complexity of channel
6114 handling with client entry and vice versa (removed one extra
6115 loop when searching for channel entry from many functions).
6117 * Changed server->sim from table to SilcDList and changed code
6120 * NAMES command can now be used from user interface. It will show
6121 the user list on the channel, neatly.
6123 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6124 Code now saves realname of the user if it becomes available.
6126 * Renamed configure.in to configure.in.pre and made ./prepare
6127 script to automatically add correct version string to
6128 configure.in which it creates from configure.in.pre.
6130 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6132 * NAMES command reply now shows users mode with the nickname when
6135 * Moved silc_client_ch[u]mode[_char] functions from
6136 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6137 place sucks, they are utility functions and should be in some
6140 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6142 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6145 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Added TRQ (efficient deque and list library) into lib/trq. This is
6150 a very good list library that is currently used in the SILC. Defined
6151 SilcList API over the library because I didn't like the API very
6152 much. See lib/trq/silclist.h for the API and examples of how to
6153 use the API. Fixed various places in the code to use the new
6154 SilcList API. The SilcList is meant for lists that has a structure
6155 already defined as a list. It is not suitable to add just some
6156 context to the list (in TRQ, the context is the list actually).
6158 So, I defined SilcDList that can be used for the purpose where
6159 predefined list structure does not exit. This can be used as
6160 such list. Now some context just can be added to the SilcDList.
6161 Currently this list is not used in the SILC just yet, though there
6162 are a lot places where this can replace dynamically allocated
6163 tables and I will fix these places, later, to use SilcDList.
6164 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6165 and use TRQ internally).
6167 Also fixed some annoying warning messages that the original TRQ
6168 code generated. Also minor changes to TRQ's Makefile.in.
6170 * Added support for querying by Client ID to both WHOIS and
6171 IDENTIFY commands into server, as required by the protocol.
6173 * Removed method function pointers from SilcBuffer structure. They
6174 weren't used to anything and just increased the context size for
6175 no good reason. This change also made silc_buffer_alloc and
6176 silc_buffer_free functions inline functions.
6178 * Disabled command flooding detection support until it's fixed so
6179 that it accepts commands in but does not execute them more than once
6182 * Added silc_net_localhost(), to return local hostname, into
6183 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6184 that must be initialized before calling silc_client_init.
6186 * Added new function: silc_server_send_notify_on_channels to send
6187 notify messages to all channels client has joined. It is assured
6188 that the message is sent only once per client.
6190 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6191 lib/silcutil/silcutil.[ch] as silc_format function. The new
6192 function is generic and is used by server as well, not only by
6193 the logging routines.
6195 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6196 the provided version string was not acceptable. Added new function:
6197 silc_ske_check_version into lib/silcske/silcske.h. The function
6198 must be implemented by the application (client or server) and it
6199 does not reside in the SKE library. The function checks the version
6200 string remote end sent.
6202 * Added back pointers (to opaque context and to SilcSocketConnection)
6203 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6205 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6206 duplicate packet context structure.
6208 * Changed `notify' client operation to send same arguments as client
6209 receives from server except for ID's. ID's are mapped to correct
6210 ID entry and that is returned. Also, if channel entry is not sent
6211 by server but the notify is for channel the channel entry is sent
6212 to application (otherwise application doesn't know that it is for
6213 channel (library gets it from packet's Destination ID)).
6215 * Added silc_client_remove_from_channels into client library to
6216 remove a client from all channels it has joined to. Used when
6217 received SIGNOFF notify from server. Added also new function
6218 silc_client_replace_from_channels to replace old ID entry with
6219 new ID entry on all channels. Used when received NICK_CHANGE
6222 * Fixed ID Cache list handling in silc_idlist_get_client in
6223 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6224 to get (or query) client by ID.
6226 * Updated TODO list.
6228 * Added connection authentication status message defined by the
6229 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6230 support for these into the code in client and server side.
6232 * Added generic function silc_client_send_command to send any command
6233 with variable argument list. Application should use this function
6234 to send commands if the command functions provided by the library
6235 does not suite for the application's user interface needs.
6237 * Added new `failure' client operation. Application is notified about
6238 received failure packet if client is executing a protocol. In this
6239 case the protocol's execution has failed.
6241 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6242 is required by the protocol.
6244 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6245 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6248 * Added status flag to SilcSKE object to indicate realtime status
6249 of the SKE protocol.
6251 * Application receives now exactly same command reply arguments as
6252 the library receives from server. However, if ID is received the
6253 corresponding ID entry is returned to the application (eg. Client
6254 ID is mapped to correct SilcClientEntry entry and that is returned).
6255 Changed command_reply client operation due to this change.
6257 * Changed all ID's in commands and in command replys as ID Payloads.
6258 Change affected both client and server side codes.
6260 All ID's sent in SILC network (with execption of ID's in SILC
6261 Packet header) are sent in ID Payload to support variable length
6264 * Server now notifies nick changes and notifies all clients on
6265 the channels about the new nickname (about the new Client ID,
6268 * Implemented CMODE command to change channel modes. Supports all
6269 channel modes defined by the protocol specs except ban and invite
6270 lists. (Also, private channel key mode is supported but support for
6271 setting private channel key in client is missing, thus, this mode
6272 has no effect on client side (except that server requires that the
6273 client uses private channel key and normal channel traffic does not
6276 Also, invite mode works per se, but INVITE command does not work
6277 yet correctly, so you can set channel as invite only channel but
6278 inviting clients to the channel does not work (it is yet to be
6279 thought what's the best way to do it).
6281 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6282 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6283 Implemented CUMODE command to change user's mode on the channel.
6284 Supports all modes defined by the protocol specs.
6286 * Added NAMES command reply to return users modes on the channel.
6288 * Removed unnecessary and slow ciphers from lib/silccrypt.
6290 * Set SO_KEEPALIVE option to connection sockets by default.
6292 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6294 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6295 redefined the Notify Payload into protocol specs.
6297 * Added silc_id_payload_parse_id to get ID directly from raw
6300 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6303 accept searching by Client ID as well.
6305 * Added support for LEAVE and SIGNOFF notify types in client library.
6307 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6308 to parse ID Payload from raw data.
6310 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Added flags parameter into silc_ske_assemble_security_properties
6313 function in lib/silcske/silcske.[ch].
6315 * Changed notify client operation to fit better for notify messages
6316 sent by server. The notify payload received from server is now
6317 passed to the application (after parsing it to SilcNotifyPayload).
6318 It is application's responsibility to retrieve the arguments
6319 from the payload and show the message the way it wants. The message
6320 sent by server is implementation specific.
6322 * Changed public keys to comply with the protocol specification.
6323 Old public keys are not supported anymore and are not compatible.
6325 * Removed nickname from Channel Payload as the latest draft removed
6326 it. The client must resolve the nickname from the NAMES command
6327 reply received when it joined the channel.
6329 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6331 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6333 * Fixed some errors in protocol specification drafts.
6335 * Created lib/silccore/silcnotify.c to implement Notify Payload
6336 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6337 generic payloads described by protocol specifications. The file
6338 includes implementations for ID Payload and Argument Payload.
6340 * Changed Command Payload implementation to use the new Argument
6341 Payload. Changed command_xxxx_payload to command_payload_xxxx
6342 to comply with SILC coding conventions.
6344 * Added suppport for Argument Payload handling in Notify Payload
6345 implementation as protocol requires it. Added the new support
6346 into server and client lib as well.
6348 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Added support for multiple nicknames on same channel. [n] is
6351 added locally to the nickname if there are more than one same
6352 nicknames on the channel.
6354 * Server now sends all nicknames that matched WHOIS request.
6355 Client also shows the list received from server.
6357 * Added TOPIC command to client side. User can now set and show
6358 current topic on channel.
6360 * Added MOTD command to client and server. Also, server sends the
6361 motd when client connects to the server.
6363 * Changed version strings to comply ISO 8601.
6365 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6367 * Fixed protocol error handling in client library. It should now
6368 cope even if the SKE fails for some reason.
6370 * Made new protocol specification drafts for submitting to IETF.
6372 * Implemented TOPIC command to server in silcd/command.c.
6374 * Added two new notify types into lib/silccore/silcnotify.h:
6375 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6376 notify nickname change and topic setting/change on a channel.
6378 * API change of command_reply operation in client library. The
6379 application gets now the status type received from server as well.
6381 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6385 * Cras fixed and optimized the packet handling even further and
6386 it should work now. Minor change to the prototype of function
6387 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6389 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6391 * Added new function into lib/silcutil/silcschedule.[ch]:
6392 silc_schedule_with_fd to select() a specified fd. The function
6393 returns after timeout expires or data arrives or goes. The
6394 function is used by packet routines to wait that all data is
6395 received from network.
6397 * Fixed data reading from network in lib/silccore/silcpacket.c.
6398 The code now assures that all data is read from the fd and then
6399 continues packet processing. This was a bug fix since the code
6400 used to drop some data in some circumstances.
6402 * Added new function into lib/silcclient/client.[ch]:
6403 silc_client_start_key_exchange to start key exchange after
6404 connection has been established to server. The code internally
6405 now uses this funtion but its main purpose was to provide it
6406 for applications that perform their own connecting. After
6407 application has created a connection it merely calls this
6408 function to start the key exchange between client and server.
6409 The library takes care of everything else after that.
6411 Updated also lib/silcclient/README to explain the usage of
6414 * Do not send to application information that connection has
6415 been established. Application gets notified it by connect
6418 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Applied cras's patch to add silc_schedule_one function. The
6421 function runs scheduler once and returns.
6423 * Fixed the scheduler after cras messed it up. The timeout
6424 handling works now as it's supposed to work.
6426 * Added into lib/silccore/ silcnotify.h to include notify
6427 message types support. Changed silc_server_send_notify*
6428 functions, in server.[ch], to support those new notify types.
6429 Added the support for the notify types into client library,
6430 as well. Added new notify client operation into ops.h in
6433 * Changed silc_server_packet_send_to_channel to send normal
6434 packets instead of just channel message packets. The function
6435 is now used to send the notify packets to channels. It is not
6436 used to send channel message packets anymore, as server never
6439 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6440 va_arg()s as it seems to require it nowadays. I guess, if SILC
6441 is compiled with older va_arg() the new code should work anyway.
6443 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Splitted core library. Core library (lib/silccore) includes
6446 now only SILC protocol specific core (and common) components.
6447 Created new utility library (lib/silcutil) that includes more
6448 generic purpose stuff. The stuff for util library was taken
6449 from the old core library. This was minor and easy split.
6451 * Created SILC Client Library (lib/silcclient) that includes
6452 implementation of the SILC client without user interface. This
6453 was major move from silc/ directory. The code has been changed
6454 so that it is transparent towards the user interface. The
6455 silc/ directory includes now the same user interface as before
6456 and it uses the new client library. Read lib/silcclient/README.
6457 Basicly, the client library performs everything else related
6458 to SILC except user interface handling. Also, configuration
6459 files are considered to be part of user interface and library
6460 does not handle them.
6462 This change also changed a lot of structures, function naming etc.
6463 Most important change was that SilcClientWindow object was
6464 renamed to SilcClientConnection in the client library. Created
6465 also new file lib/silcclient/ops.h. Also added new files
6466 silc/local_command.[ch] and silc/client_ops.[ch].
6468 All these changes were made to make it easier for user interface
6469 designers to create what ever user interface for the SILC client
6472 It is also expected that the server will be moved to lib
6473 directory as well and SILC Server Library will be created;
6474 sometimes in the future.
6476 * Removed Local commands from lib/silccore/silccommand.h as
6477 they are application specific and new client library does not
6478 handle any of those anymore.
6480 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6481 old client implementation in silc/.
6483 * Added support for callback functions in SILC_LOG_* macros.
6484 Application can now set its own callbacks that will be called
6485 instead of using the default functions that will always print
6486 the debug messages to stderr (or stdout). Also, debugging can
6487 now be disabled by setting silc_debug to FALSE and re-enabled by
6488 setting it to TRUE. Note, that logging will still work even
6489 if debugging is disabled.
6491 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6492 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6493 silc_log_reset_debug_callbacks.
6495 * To enable debugging in silc client one must give now -d
6496 option on command line.
6498 * Changed silc_schedule_init to automatically allocate task queues
6499 if they are not allocated before calling it.
6501 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Added GMP 3.1 into math library.
6505 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6508 a channel in SILC network. The packet is used by servers and
6509 routers to notify other routers that user has left a channel.
6510 This little feature was missing until now. Added the feature
6511 to protocol specification as well.
6513 Added functions: silc_server_send_remove_channel_user and
6514 silc_server_remove_channel_user into server.[ch].
6516 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6517 lib/silccore/silcpacket.h. However, they are not implemented
6520 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Fixed joining to a channel and sending channel messages
6523 between server and router. The channel message sending should
6524 now work inside a cell.
6526 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Fixed the private message sending between server and router.
6529 The private message sending should now work inside a cell.
6531 * Added silc_server_replace_id into server.[ch] to replace
6532 existing ID in the SILC network.
6534 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6535 and silc_idlist_replace_server_id into idlist.[ch] in server.
6537 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * Fixed the server to server connections. Server can again now
6540 connect to router. Router to router connections probably does
6543 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6545 * Added dynamic protocol registering support. Now protocols can
6546 registered and unregistered on the fly. Patch by cras.
6548 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Added lib/contrib directory to hold routines that some platforms
6551 don't have but are needed by SILC.
6553 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6554 into lin/contrib to provide getopt() and getopt_long() for
6555 those who don't have it.
6557 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Added AWAY command to client. When away message is set and
6560 client receives a private message packet the client automatically
6561 replies to the sender with the away message.
6563 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6564 bug seemed to be the cause of recent problems when compiling
6567 * Added version detection support to SKE protocol specification
6568 and added the new changes to the SKE implementation as well.
6569 There were other minor changes in the SKE protocol as well.
6571 Many changes in lib/silcske/silcske.[ch] and in
6572 lib/silcske/payload.[ch].
6574 * Added ^U functionality, clear input line. Patch from cras.
6576 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Mainly small bugfixes on core library. Fixed some debugging
6579 logging and buffer overflow in silclog.c.
6581 * Updated config.sub and config.guess on the distribution tree.
6583 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Added command lagging support in server. Client may execute
6586 commands now only once in two seconds.
6588 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Optimized packet reception. MAC computation and checking is now
6591 also more optimized. A lot previously duplicated code is now
6592 used as generic by both client and server.
6594 * Fixed key pair generation in clientutil.c
6596 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Added into lib/silccore/silcbufutil.[ch] new function;
6599 silc_buffer_realloc.
6601 * Moved generic packet sending/encryption functions to
6602 lib/silccore/silcpacket.[ch] from client and server. Some
6603 rewriting of the functions.
6605 * Moved all generic packet reception/decryption functions to
6606 lib/silccore/silcpacket.[ch] from client and server. The
6607 packet processing is now much cleaner in both client and server.
6608 These were major changes in both client and server.
6610 * Created many common functions in server to do packet sending.
6611 Previously code were duplicated a lot, this has been removed
6614 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6616 * Rewrote major parts of the ID cache system. Don't know
6617 whether it is better now or not but at least the API is more
6620 * Major rewrite on ID cache stuff on client because of the ID
6621 cache API changes. Added idlist.c to client.
6623 * Also major rewrite on ID cache stuff on server as well.
6624 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6625 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6626 in hand, instead they are all put into the ID cache system now.
6627 All server_idlist_* routines uses ID cache now instead of
6628 traversing its own lists (those lists does not exist anymore).
6629 SilcIDList though still exists. Also, SilcXXXEntry's are
6632 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Finally made the SKE implementation compliant to the protocol
6635 specification. All mp integers are now binary encoded as
6636 opposed being HEX encoded.
6638 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6641 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6642 functions: silc_[encode/decode]_pem. Also added function
6643 silc_encode_pem_file to PEM encode with newlines ('\n') for
6646 * SILC public keys are now encoded either PEM or binary. Same
6647 option is for private keys as well. By default private keys
6648 are binary encoded and public keys PEM encoded. Silly HEX
6649 encoding were removed.
6651 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6652 function to create fingerprints.
6654 * Fixed a bug in SHA1; does not change the original data anymore.
6656 * Partly implemented INFO command on client and server side.
6657 Fixed CLEAR command. Changes to SERVER command; show current
6658 server(s) when giving command without arguments. Added
6659 VERSION command to client.
6661 * Added check to server that unregistered connections cannot
6662 execute commands (unless it is specificly allowed).
6664 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Fixed screen refresh.
6668 * Fixed channel joining bug from client. On some circumstances
6669 client tried to join to a channel it had already joined.
6671 * Added public key verification process into client's protocol.c.
6672 The client now verifies the public key from user and saves
6673 it into ~./silc/serverkeys/ directory.
6675 Added into: clientutil.[ch]: silc_client_verify_server_key.
6677 * Changed SKE protocol's silc_ske_initiator_finish function
6678 to accept callback function that verifies the received public
6679 key. Removed old silc_ske_verify_public_key function.
6681 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6684 silc_pkcs_private_key[_data]_set.
6686 * Made the password and public authentication more cleaner in
6687 server's protocol.c.
6689 * Removed historic and obsolete protocol `channel_auth' from
6690 both client and server.
6692 * Removed wrong way of sending command status messages from
6693 server to client in server's command.c. The old way violated
6694 protocol specification.
6696 Changes to silccore/silccommand.[ch]: removed
6697 silc_command_encode_status_payload -> not needed anymore,
6698 changed silc_command_encode_payload_va to accept extra
6699 argument on variable argument list. The argument type must
6700 now be provided to the function. Also, added new function:
6701 silc_command_encode_reply_payload_va which is same as
6702 normal command_encode_payload_va except command status type
6703 is provided as extra argument.
6705 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Added ~./silc directory handling. The directory includes the
6708 public and private keys for the client.
6710 Added silc_client_check_silc_dir, silc_client_create_identifier
6711 and silc_client_load_keys.
6713 * Implemented SILC protocol compliant public key. Added public
6714 and private key saving to and loading from files.
6716 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6717 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6718 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6719 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6720 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6722 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6723 silc_pkcs_load_[public/private]_key.
6725 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6727 * Added silc_server_get_route (route.[ch]) to get connection
6728 data for the fastest route for given ID.
6730 * Implemented INVITE command on client and server. The command
6731 were re-defined in the SILC Protocol Specification and the
6732 implementation now complies with the specification.
6734 * Implemented PING command on client and server.
6736 * Implemented NAMES command on client and server. The server side
6737 supports currently only normal server not router server yet.
6738 Some changes to NAMES definition in SILC protocol specification.
6740 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Implemented LEAVE command on client and server.
6744 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6745 again. This change was made to the protocol as well. Server
6746 should not violate the protocol specification anymore.
6748 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6751 was tested. SOCKS4 was not but should work anyway.
