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

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

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

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

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

788 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
790 * Use ++server->cmd_ident when sending commands in server,
791 instead of random number. Affected file silcd/command.c.
793 * Fixed GETKEY command reply to call actually GETKEY pending
794 command callbacks. Affected file silcd/command_reply.c.
796 * A bit stricter check for nicknames. Check for same nickname
797 in NICK command also. Affected file silcd/command.c.
799 * Do not call INFO command everytime client ID changes, only
800 during first connecting. Affected file lib/silcclient/client.c.
802 * Set the new nickname only after successful command reply for
803 NICK command is returned by server. Affected file
804 lib/silcclient/command.c.
806 * Remove nicknames from nicklist during server_signoff notify.
807 Should fix /NAMES bit more. The affected file is
808 irssi/src/silc/core/silc-channels.c.
810 * Added `fingerprint' field to the SilcIDListData in the
811 silcd/idlist.h to hold the fingerprint of the client's
814 Send the fingerprint of the client's public key in WHOIS
817 Affected files silcd/command.c, and silcd/idlist.[ch].
819 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
820 create fingerprint from given data.
822 * Show the fingerprint of the client's public key in WHOIS.
823 Affected files irssi/src/module-formats.[ch] and
824 irssi/src/silc/core/client_ops.c.
826 * Format the multiple same nicknames also during JOIN and
827 NICK_CHANGE notifys. Affected file is
828 lib/silcclient/client_notify.c.
830 * Do not print error on screen for invalid private message
831 payload since it can come if someone is sending private
832 messages with wrong key. Affected file
833 lib/silccore/silcprivate.c.
835 * Fixed multiple concurrent /PING crash. Affected file
836 lib/silcclient/command.c.
838 * Changed the wrong ID encoding. All IP addresses must be
839 in MSB first order in encoded format. They were encoded
840 wrong and was in LSB format. Affected files are
841 silcd/serverid.c, lib/silcutil/silcutil.c.
843 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
845 * Call the `connect' client operation through the scheduler
846 in case of error. Affected file lib/silcclient/client.c.
848 * Call the `failure' client operation even if the error
849 occurred locally during a protocol. Affected file is
850 lib/silcclient/protocol.c.
852 * Added support of sending LIST command to router from normal
853 server. This way normal server can get list of all channels
854 in the network too. Fixed the channel list sending in the
855 server too. Affected files are silcd/command.c, and
856 silcd/command_reply.[ch].
858 * Added silc_server_update_channels_by_server and
859 silc_server_remove_channels_by_server. They are used during
860 disconnection of primary router and in backup router protocol.
861 Affected file silcd/server_util.[ch], silcd/server.c and
862 silcd/server_backup.c.
864 * Fixed channel adding to global list in IDENTIFY command
865 reply in server. Affected file silcd/command_reply.c.
867 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
869 * If the incoming packet type is REKEY or REKEY_DONE process
870 that packet always synchronously. Fixes yet another MAC
871 failed error on slow (dialup) connections. Affected file
872 lib/silcclient/client.c and silcd/server.c.
874 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
876 * Call check_version SKE callback for initiator too. Affected
877 file lib/silcske/silcske.c.
879 * Implemented fix for security hole found in the SKE that was
880 fixed in the specification few days back; the initiator's
881 public key is now added to the HASH value computation.
882 Added backwards support for the old way of doing it too, for
883 old clients and old servers. Affected file is
884 lib/silcske/silcske.c.
886 * Enabled mutual authentication by default in SKE. If initiator
887 is not providing mutual authentication the responder will
888 force it. This will provide the proof of posession of the
889 private key for responder. The affected files are
890 lib/silcclient/protocol.c and silcd/protocol.c.
892 * Do not cache anymore the server's public key during SKE.
893 We do mutual authentication so the proof of posession of
894 private key is done, and if the server is authenticated in
895 conn auth protocol with public key we must have the public
896 key already. Affected file silcd/protocol.c.
898 * Added new global debug variable: silc_debug_hexdump. If
899 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
900 file lib/silcutil/silclog.[ch].
902 * Fixed compilation warning due to char * -> const char *.
903 Affected files lib/silcutil/silcnet.h, and
904 lib/silccore/silcauth.[ch].
906 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
908 * Fixed CMODE command when new channel key was created. If
909 the creation failed the old key was removed. Next time giving
910 same command would crash the server since the old key was
911 freed already. Affected file silcd/command.c.
913 * Fixed the silc_server_announce_get_channels to not crash
914 on reconnect. Affected file silcd/server.c.
916 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Added silc_log_set_debug_string function to set a regex
919 string to match for debug output. Only the function names,
920 or filenames matching the given debug string is actually
921 printed. This way it is possible to filter out those debug
922 strings that user is not interested in.
924 Fixed a bug in silc_string_regexify.
926 Affected files lib/silcutil/silclog.[ch], and
927 lib/silcutil/unix/silcunixutil.c.
929 * Changed the -d options in both server and Irssi SILC client
930 to take the debug string as argument. Affected files
931 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
933 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
935 * Added silc_hash_babbleprint to create a Bubble Babble
936 Encoded fingerprint. The encoding is developed by Antti
937 Huima (draft-huima-babble-01.txt), and it creates human
938 readable strings out of binary data. Affected file
939 lib/silccrypt/silchash.[ch].
941 * Print the babble print now in addition of fingerprint as well
942 in Irssi SILC client. Affected files are
943 irssi/src/fe-common/silc/module-formats.[ch],
944 irssi/src/fe-common/silc/core/client_ops.c.
946 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
948 * Fixed a security problem found in SKE. The initiator's
949 public key too is now added to the HASH hash value creation
950 which is signed by the responder to create the SIGN value.
951 This will prevent anyone in the middle to lie to the responder
952 about the initiator's public key. If this is done now, the
953 man in the middle will get caught. Updated the protocol
956 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Better installation directory handling. Configure module
959 paths and other paths automatically to example_silc* files
960 in doc/. A patch by toma.
962 * Fixed compiler warning from MPI library, and from SILC RNG.
965 * Added SILC_SERVER_PID_FILE to define the pid file for server.
966 It can be configured with ./configure. A patch by toma.
968 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
970 * Find correct make to use in prepare-clean. A patch by
971 toma. Affected file prepare-clean.
973 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
975 * Added irssi variables use_auto_addr, auto_bind_ip,
976 auto_bind_port and auto_public_ip.
978 * Changed the interface for silc_client_send_key_agreement
979 in lib/silcclient/silcapi.h
983 irssi/src/silc/core/silc-core.c
985 lib/silcclient/silcapi.h
986 irssi/src/silc/core/silc-channels.c
987 lib/silcclient/client_keyagr.c
990 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Added silc_pkcs_public_key_compare to compare two
993 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
995 * Check that the client who set the founder mode on the
996 channel is the same client that is giving the founder
997 mode to itself. It is done by comparing the saved public
998 key (it is saved even in the authentication is passphrase).
999 Affected file silcd/command.c.
1001 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Do not process packet for disconnected socket connection.
1004 Affected file lib/silccore/silcpacket.c.
1006 * Process the DISCONNECT packet through scheduler in the
1007 client library. Affected file lib/silcclient/client.c.
1009 * Fixed the silc_client_packet_parse to not to increase
1010 the packet sequence number if the conn->sock and the
1011 current socket connection is not same. This can happen
1012 for example during key agreement when the conn includes
1013 multiple socket connections (listeners). Affected file
1014 lib/silcclient/client.c.
1016 * The sender of the file transfer request now provides also
1017 the pointer (listener) for the key exchange protocol. If
1018 the listener cannot be created then it sends empty key
1019 agreement and lets the receiver provide the listener.
1021 Added `local_ip' and `local_port' arguments to the
1022 silc_client_file_send. If they are provided they are used,
1023 if not then it will attempt to find local IP address, if
1024 not found or bind fails then the remote client will provide
1027 Affected files are lib/silcclient/client_ftp.c and
1028 lib/silcclient/silcapi.h.
1030 * Extended the FILE SEND command to support defining the
1031 local IP and port for key exchange listener. They are
1032 optional. Affected file irssi/src/silc/core/silc-servers.c.
1034 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1036 * Defined to WHOIS command reply the sending of fingerprint
1037 of the client's public key (if the proof of posession of the
1038 corresponding private key is verified by the server).
1039 Updated to the protocol specification.
1041 * Added support of receiving the client's public key's
1042 fingerprint in command reply in client library. Affected
1043 file is lib/silcclient/command_reply.c, and
1044 lib/silcclient/idlist.[ch].
1046 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Do not send over 128 chars long nickname to the server
1049 in NICK command. Affected file lib/silcclient/command.c.
1051 * Do not send over 256 chars long channel names to the server
1052 in JOIN command. Affected file lib/silcclient/command.c.
1054 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Assure that silc_server_close_connection cannot be called
1057 twice for same socket context. Affected file is
1060 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Send error message to application if opening file for
1063 writing during file transfer fails. Affected file is
1064 lib/silcclient/client_ftp.c.
1066 Remove all file transfer sessions for a client that we're
1067 removing from ID cache.
1069 Affected file is lib/silcclient/client_ftp.c.
1071 * Fixed silc_net_addr2bin to return correct address. Affected
1072 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1074 * Fixed file transfer session removing on signoff notify.
1075 Affected file irssi/src/silc/core/silc-servers.c.
1077 * Added the SilcClientFileError to be returned in the monitor
1078 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1079 Affected file lib/silcclient/silcapi.h.
1081 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1083 * Fixed a crash in silc_client_ftp_free_sessions and
1084 silc_client_ftp_session_free_client. Affected file
1085 lib/silcclient/client_ftp.c.
1087 * Added `disabled' field in the SilcChannelEntry in the server
1088 to indicate if the server entry is disabled. Affected file
1089 silcd/idlist.h, silcd/command[_reply].c.
1091 * SILC server adds now /var/run/silcd.pid everytime it is
1092 started. Affected file silcd/silcd.c.
1094 * Added silc_server_packet_send_clients to send a packet to
1095 the provided table of client entries. Affected file
1096 silcd/packet_send.[ch].
1098 * Fixed a crash in client resolving in client_prvmsg.c in
1099 client library. Affected file lib/silcclient/client_prvmsg.c.
1101 * Do not actually remove the client directly from ID cache
1102 during SERVER_SIGNOFF, but invalidate it. This way we
1103 preserve the WHOWAS info for the client. Affected file
1104 silcd/server_util.c.
1106 * Fixed SERVER_SIGNOFF notify handling in the server. The
1107 server is now able to process incoming SERVER_SIGNOFF notify
1108 for a server that it doesn't even know about. It will remove
1109 the clients provided in the notify. Affected file
1110 silcd/packet_receive.c.
1112 * Check for partial packet in data queue after every packet that
1113 was found from the queue. Return and wait for more data if
1114 there is partial data in queue. Affected file is
1115 lib/silccore/silcpacket.c.
1117 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1119 * Added SilcClietFileError enum to indicate error in
1120 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1126 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1128 * Added better monitor of file transfers. It now monitors
1129 key agreement protocol during the file transfer too. Added
1130 error reporting too. Affected files
1131 irssi/src/silc/core/silc-servers.c,
1132 irssi/src/fe-common/silc/module-formats.[ch].
1134 * Wrote a help file for FILE command.
1136 * Added silc_rng_global_get_byte_fast to get not-so-secure
1137 random data as fast as possible. Random data is read from
1138 /dev/urandom if available and from the SILC RNG if not
1139 available. It is used in padding generation. Affected file
1140 lib/silccrypt/silcrng.[ch].
1142 * All packets in client library are now processed synchronously.

1155 * Assure that silc_client_notify_by_server_resolve does not
1156 resolve the client information multiple times. If it cannot
1157 be found by the first it cannot be found at all. Affected
1158 file lib/silcclient/client_notify.c.
1160 * Fixed WHOWAS command reply calling. Affected file
1161 lib/silcclient/command_reply.c.
1163 * Removed all references to silc_idlist_get_client from the
1164 Irssi SILC client since that call is internal call used by
1165 the library. The Irssi SILC client will use now client
1166 retrieval functions found in silcapi.h.
1168 * Fixed a bug in resolving nickname info before sending
1169 private message. It used freed memory. Affected file
1170 irssi/src/silc/core/silc-servers.c.

1191 * Added silc_net_localip to return local host's IP address.
1192 Affected file lib/silcutil/silcnet.[ch].
1194 * If key exchange or rekey protocol is active for a connection
1195 parse all packets syncronously since there might be packets
1196 in packet queue that we are not able to process without first
1197 processing packets before them. Affected file silcd/server,
1198 lib/silcclient/client.c.
1200 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1201 whether library should continue processing the packet.
1202 Affected file lib/silccore/silcpacket.h.

1248 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1249 is incomplete and is being resolved, it won't be resolved
1252 Make sure also that USERS command reply does not resolve
1253 twice information. Affected file is
1254 lib/silcclient/command_reply.c.
1256 Make sure that silc_client_get_clients_by_list does not
1257 resolve twice same information.
1259 * Check for valid client->id in the silc_server_free_client_data.
1260 Affected file silcd/server.c.
1262 * Fixed /GETKEY nick@server not to crash if the server entry
1263 is not found. Affected file lib/silcclient/command.c.
1265 * Fixed the silc_server_check_cmode_rights to check the
1266 requested modes correctly. Affected file silcd/command.c.

1271 Affected file silcd/command.c.
1273 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1275 * Call the silc_server_udpate_servers_by_server in the
1276 primary router that comes back online in the backup resuming
1277 protocol. Otherwise it routes packets wrong. Affected file
1278 silcd/server_util.[ch], silcd/server_backup.c.
1280 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1283 lib/silcutil/silcbuffmt.[ch].
1285 * Redefined the SILC packet header to include the padding
1286 length. Affected file lib/silccore/silcpacket.[ch].
1288 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1289 length for maximum padding up to 128 bytes). Affected
1290 file lib/silccore/silcpacket.h.
1292 * Removed all backwards support for old 0.5.x MAC thingies.
1293 The SILC packet header change makes it impossible to be
1294 backwards compatible.
1296 * Send the ENDING packet with timeout in the backup resuming
1297 protocol. This is to assure that all routers has connected
1298 to the primary router. Affected file silcd/server_backup.c.
1300 * Changed the RNG to take the first IV from random data. It
1301 used to take it from zero actually. Changed the RNG also
1302 to use /dev/urandom during session. /dev/random is used
1303 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1305 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1307 * Changed the SILC packet header to have the first two bytes
1308 (the packet length) encrypted. Affected files aroung the
1309 code tree, lib/silccore/silcpacket.[ch]. Removed the
1310 SilcPacketCheckDecrypt callback. It is not needed anymore
1311 since the silc_packet_receive_process will determine now
1312 whether the packet is normal or special.
1314 * Implemented the unidirectional MAC keys. Affected files
1315 lib/silcske/silcske.c, silcd/protocol.c and
1316 lib/silcclient/protocol.c.
1318 * Implemented the packet sequence number to the MAC computation.
1319 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1320 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1321 lib/silcclient/protocol.c.
1323 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Allow backup router to announce servers. All servers
1326 announced by backup router are added to the global list
1327 automatically. Update hte server's socket to our primary
1328 router also when backup router announces a server.
1329 Affected file silcd/packet_receive.c.
1331 * Do not update the client->router in the function
1332 silc_server_udpate_clients_by_server if the client is on
1333 global list. We might fail to find any specific server
1334 for locally connected clients and local cell clients. They
1335 should still use the `from' and not `to' as client->router.
1336 This fixes backup router resuming protocol. Affected file
1337 silcd/server_util.c.
1339 * Decrease channel statistics count only if the channel
1340 deletion worked. Affected files are silcd/server.c and
1341 silcd/server_util.c.
1343 * Added silc_server_update_servers_by_server to update origin
1344 of all server entries. Used during backup router protocol.
1345 Affected files silcd/server_util.[ch], silcd/server.c. and
1346 silcd/backup_router.c.
1348 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1349 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1350 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1351 lib/silccrypt/silchmac.c.
1353 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1355 * Assure that router cannot reroute the same channel message
1356 to the sender. Affected file silcd/packet_receive.c.
1358 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1360 * Made better checks that the channel message is not sent
1361 to the router it came from. Affected file is
1362 silcd/packet_send.c. Fixed memory leak too.
1364 * Announce informations for incoming router connection, but
1365 only after checking if it is replaced by backup router.
1366 Affected file silcd/packet_receive.c.
1368 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1370 * Fixed the backup resuming protocol to work in multiple
1371 router environment. Affected file silcd/server_backup.c.
1373 * Route packet only to one router in the function
1374 silc_server_packet_send_to_channel. Affected file is
1375 silcd/packet_send.c.
1377 * Fixed silc_server_send_notify_dest to set the broadcast
1378 flag. Fixed the silc_server_send_notify_topic to actually
1379 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1380 Affected file silcd/packet_send.c.
1382 * Changed the SFTP Filesystem interface. Changed the
1383 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1384 the filesystem operation function. The SilcSFTPFilesystem
1385 is now a context that is allocated by all filesystem allocation
1386 functions and it already includes the operations structure
1387 and filesystem specific context. It is given as argument
1388 now to the silc_sftp_server_start. This made the interface
1389 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1390 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1392 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1394 * Changed the backup router adding and getting interfaces
1395 in the server. The router that will be replaced by the
1396 specified backup router is now sent as argument. Affected
1397 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1400 * Added silc_net_addr2bin_ne to return the binary form of
1401 the IP address in network byte order. Affected files
1402 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1404 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Check for existing server ID in silc_server_new_server
1407 and in silc_server_connect_to_router_final and remove the
1408 old entry if it exists. Affected file silcd/packet_receive.c,
1411 * Send the channel message always to only one router, either
1412 in upstream or downstream. Affected file is
1413 silcd/packet_send.c.
1415 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * Wrote the definition of the backup resuming protocol to the
1418 protocol specification.
1420 * Removed one redundant channel key generation from normal
1421 server during joining procedure. Removed one redundant
1422 channel key sending from server to router during joining
1423 procedure. Affected file silcd/command.c.
1425 * Made minor bugfixes to the backup router resuming protocol.
1426 Affected file silcd/server_backup.c, server.c.

1431 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1434 * Implemented the backup resuming protocol that is used to
1435 resume the primary router position in the cell after the
1436 primary router comes back online. Affected files
1437 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1438 and silcd/server_util.[ch].
1440 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Sleep two (2) seconds after sending QUIT command to server.
1443 Affected file lib/silcclient/command.c.
1445 * Assure that if outgoing data buffer is pending do not force
1446 send any data. Affected file silcd/packet_send.c.
1448 * Assure that if outgoing data buffer is pending do not force
1449 send any data. Affected file lib/silcclient/client.c.
1451 * Implemented the backup router support when the primary router
1452 goes down. The servers and routers can now use the backup
1453 router as new primary router without loosing connectivity.
1455 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1458 in the server to indicate disabled entry. All data read
1459 from the connection will be ignored and no data is sent
1460 for entry that is disabled. Affected files are
1461 silcd/idlist.h, silcd/server.c.
1463 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1465 * Created SFTP client and server test programs in the
1466 lib/silcsftp/tests directory.
1468 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Implemented memory filesystem (virtual filesystem) for
1471 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1474 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Implemented the SFTP (SSH File Transfer Protocol) to the
1477 lib/silcsftp. It includes SFTP client and SFTP server
1480 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Moved lib/silccore/silcprotocol.[ch] to the
1483 lib/silcutil library.
1485 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1486 take variable argument list pointer as argument. Affected
1487 file lib/silcutil/silcbuffmt.[ch].
1489 * Added silc_buffer_set function that is used to set data
1490 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1491 Affected file lib/silcutil/silcbuffer.h.
1493 * Changed various routines in the core library to use the new
1494 silc_buffer_set instead of allocating new buffer only for
1497 * Added 64-bit value formatting and unformatting support to the
1498 silc_buffer_[un]format routines. Affected file is
1499 lib/silcutil/silcbuffmt.[ch].
1501 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1502 to includes/bitmove.h.
1504 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Fixed channel user mode saving in client library. Affected
1507 file lib/silcclient/command[_reply].c.
1509 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1511 * Defined the file transfer to the SILC Protocol. Added
1512 new packet type SILC_PACKET_FTP and defined File Transfer
1513 Payload. The mandatory file transfer protocol is SFTP
1514 (SSH File Transfer Protocol). Affected file in addition
1515 of the internet draft is lib/silccore/silcpacket.h.
1517 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1518 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1519 is used as part of backup router protocol when the primary
1520 router of the cell is back online and wishes to resume
1521 the position as primary router.
1523 * Redefined the MAC generation keys in the protocol. The
1524 same key is not used anymore in both direction. Both
1525 direction will now use different keys for sending and
1526 receiving. This fixes a potential security flaw. This
1527 change causes incompatibilities in the protocol.
1529 * Redefined also the MAC computation from the packet.
1530 An packet sequence number is now added to the MAC
1531 computation. This prevents possible replay attacks against
1532 the protocol. This change too causes incompatibilities
1535 Added `sequence' field to the SilcPacketContext to hold
1536 the current sequence number for the packet.
1538 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Added `created' field to the SilcIDListData in the file
1541 silcd/idlist.h to indicate the time when the entry was
1544 * Added `created' field to the SilcChannelEntry too. Affected
1545 file silcd/idlist.h.
1547 * Added `creation_time' aguments to all the announcement functions
1548 in the server. If it is provided then only the entries that
1549 was created after the provided time frame are actually
1550 announced. Affected file silcd/server.[ch].
1552 * The protocol says that the Channel ID's IP address must be
1553 based on the router's IP address. Added check for this in
1554 the silc_server_new_channel when processing incoming New Channel
1555 Payload. Affected file silcd/packet_receive.c.
1557 * Print out the correct version with --version in SILC client.
1558 Affected file irssi/src/silc/core/silc-core.c.
1560 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Fixed WHOWAS command to check for completnes of the client
1563 entry always, not just when the command is coming from client.
1564 Affected file silcd/command.c.
1566 * Added new function silc_server_packet_queue_purge to purge the
1567 outgoing data queue to the network. After the function returns
1568 it is guaranteed that the outgoing packet queue is empty.
1569 Affected file silcd/packet_send.[ch].
1571 * Purge the outgoing packet queue in the rekey protocol's final
1572 callback to assure that all rekey packets go to the network
1573 before quitting the protocol. Affected file silcd/server.c.
1575 * Added silc_client_packet_queue_parse as similar function as
1576 in server to the client library. The affected file is
1577 lib/silcclient/client.c.
1579 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Splitted silcd/server.c and created silcd/server_util.[ch]
1582 for utility functions.
1584 * Added new socket flag SILC_SF_DISABLED to indicate that the
1585 connection is open but nothing can be sent to or received from
1586 the connection. Affected file lib/silcutil/silsockconn.[ch].
1587 The checking for disabled socket is checked in the low level
1588 silc_socket_write and silc_socket_read functions.
1590 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Allow only nicknames and channel names that fits into the
1593 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1595 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * When processing JOIN command reply in server check that if
1598 the channel exists in our global list we'll move it the local
1599 list. Affected file silcd/command_reply.c.
1601 * Fixed the check whether client is joined on the channel already
1602 in JOIN command. Affected file lib/silcclient/command.c.
1604 * Fixed the JOIN command reply to check whether the channel
1605 already exists. Affected file lib/silcclient/command_reply.c.
1607 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Added silc_ske_status_string to map the SKE error numbers
1610 to readable strings. The affected files are
1611 lib/silcske/silcske[_status].[ch].
1613 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Do not show the private channels on the WHOIS channel list
1616 as it is not allowed by the protocol. The affected file is
1619 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1621 * Assure that the packet length digged from the actual packet
1622 is something sensible in the silc_packet_decrypt_rest_special
1623 in lib/silccrypt/silcpacket.c.
1625 * Free and NULL the allocated pointer in silc_hmac_alloc if
1626 the HMAC allocation fails. The affected file is
1627 lib/silccrypt/silchmac.c.
1629 * Print the selected security properties to the log files in
1630 the server. Affected file silcd/protocol.c.
1632 * Add SKE's reference counter even if calling the completion
1633 callback manually. Otherwise it goes negative, although it
1634 does not cause any problems. The affected file is
1635 lib/silcske/silcske.c.
1637 * Remove the client entry with short timeout after giving the
1638 KILL command. Affected file lib/silcclient/command.c.
1640 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1641 case all found clients are already disconnected (WHOWAS would
1642 found them) in the server. Affected file silcd/command.c.
1644 * Update the last_receive (time of last data received) to be
1645 updated only when received private or channel message so that
1646 the idle time showed in WHOIS makes more sense.
1648 * Added boolean field `valid' in to the SilcClientEntry in the
1649 client library to indicate whether the entry is valid or not.
1650 This fixes the nickname change bug on channel when changing
1651 the nickname to be same than the old (like nick to Nick) the
1652 nickname formatter doesn't set the new nick anymore to Nick@host.
1653 Affected file lib/silcclient/idlist.[ch].
1655 * Now actually fixed the nickname changing on disconnection.
1656 Added new function silc_change_nick to the Irssi SILC Client.
1657 Affected file irssi/src/silc/core/client_ops.c,
1658 irssi/src/silc/core/silc-nicklist.[ch].
1660 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Check that the public key exists in the GETKEY command before
1663 trying to encode it. Affected file silcd/command.c.
1665 * Print some notifications on received public keys with GETKEY
1666 command in the Irssi SILC Client. Affected files are
1667 irssi/src/fe-common/silc/module-formats.[ch],
1668 irssi/src/silc/core/client_ops.c.
1670 * Use IDENTIFY command to resolve the server information in the
1671 GETKEY command instead of INFO command. Affected file
1672 lib/silcclient/command.c.
1674 * All command reply functions in the client library now calls
1675 the pending command reply callbacks even if an error has
1676 occurred. The server has done this a long time and now it was
1677 time to move the client library to this as well. Now all
1678 errors can be delivered back to the pending command reply
1679 callbacks if necessary. Affected files are
1680 lib/silcclient/command[_reply].[ch].
1682 * Change the nickname on disconnection back to the username
1683 because in reconnect the server will enforce it to it anyway.
1684 Affected file irssi/src/silc/core/silc-servers.c.
1686 * Fixed a config file parsing bug in the Irssi SILC client.
1687 Affected file irssi/src/silc/core/clientconfig.c.
1689 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1691 * When printing the channel mode on JOIN, verify that the
1692 channel key and channel's HMAC are valid. Affected file
1693 irssi/src/silc/core/client_ops.c.
1695 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1698 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1699 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1701 * Removed channel key rekey task deleting from the function
1702 silc_server_save_channel_key. Affected file silcd/server.c.
1703 Added explicit timeout task context instead that is used to
1704 delete the task if we are registering a new task before the
1705 new task has elapsed.
1707 * When channel key rekey occurs the client library now saves
1708 the old channel key for a short period of time (10 seconds) and
1709 is able to use it in case some is still sending channel
1710 messages encrypted with the old key after the rekey. Affected
1711 file lib/silcclient/[idlist.h|client_channel.c].
1713 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Added check to the silc_server_new_id_real to not accept
1716 new ID if it is the sender's own ID. Affected file is
1717 silcd/packet_receive.c.
1719 * Assure that we do not announce ourself or the one we've
1720 sending our announcements when we're router and are announcing
1721 servers to our primary router. Affected file silcd/server.c.
1723 * Fixed silc_server_command_identify_check_client to assemble
1724 correct WHOIS packet. It send corrupted WHOIS packet and
1725 caused problem with router to router connections. Affected
1726 file silcd/command.c.
1728 Fixed also silc_server_command_whois_check the same way
1729 as for the IDENTIFY command.
1731 * Added new SilcIDListStatus to the server in the SilcIDListData
1732 structure. The status now includes the current status of
1733 the entry (like registered, resolved etc.). Affected file
1734 silcd/idlist.[ch]. Defined a bunch of different status types
1735 as well. This replaced the old boolean registered field as well.
1737 Added resolve_cmd_ident field to the SilcClientEntry structure
1738 too so that if the entry is for example being resolved so
1739 another command may attach to the same pending command reply
1740 without requiring to resolve the same entry again. This concept
1741 should optimize the WHOIS and the IDENTIFY resolving under
1742 heavy load by taking away unnecessary resolving for entries
1743 that are being resolved already.
1745 Added support for adding multiple pending commands for one
1746 command idenfier. Affected file silcd/command[_reply].[ch].
1748 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1749 before deleting the data. Otherwise the hash table will have
1750 freed data in comparison functions. Affected file is
1751 silcd/command_reply.c.
1753 * Fixed silc_idlist_replace_client_id to add the new entry to
1754 the cache with NULL nickname. Otherwise there will be invalid
1755 memory as the nickname after the nickname is freed. Affected
1756 file silcd/packet_receive.c.
1758 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1759 saved into wrong slots because the previous number of entries
1760 was not taken into account. Affected file silcd/idlist.c.
1761 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1763 * If we are router and we receive JOIN notify to a channel that
1764 does not have any users then notified client is marked as the
1765 channel founder, as it is it. The affected file is
1766 silcd/packet_receive.c
1768 * Added to the extended hash table API's table_del_*ext functions
1769 the destructor as argument too, so that the caller can decide
1770 which destructor to use or whether to use destructor at all.
1771 Affected file lib/silcutil/silchashtable.[ch].
1773 * Fixed ID Cache purging. It actually deleted the entries from
1774 the hash table after the data was freed. The hash table ended
1775 up comparing freed memory. The affected file is
1776 lib/silccore/silcidcache.c.
1778 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * Fixed Irssi SILC client's KILL command's HELP syntax.
1782 * The USERS command now resolves the detailed user information
1783 if the userinfo field is missing. Affected file is
1784 lib/silcclient/command_reply.c.
1786 * Do not print error in silc_file_read if the read file does
1787 not exist. Just silently return NULL. Affected file is
1788 lib/silcutil/silcutil.c.
1790 * Fixed the silc_log_output to not wine about NULL filename
1791 and to not create some bogus " " filename. Affected file is
1792 lib/silcutil/silclog.c.
1794 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Fixed various printing bugs on the user interface in the
1797 Irssi SILC Client. Minor changes that were forgotten from
1800 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Fixed the configure.in.pre and the compilation and distribution
1803 environment to support the new autoconf 2.52. That version is
1804 now required to compile the CVS trunk.
1806 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1809 to generally parse user@fqdn format strings. Affected file
1810 lib/silcutil/silcutil.c.
1812 * Added nickname_format and nickname_force_format fields to the
1813 SilcClientParams structure. The first one defines the format
1814 for the nicknames that the library will enforce if the receives
1815 multiple same nicknames. The second one is boolean value and
1816 can be used to force the library to always enforce the format
1817 to the nicknames regardles whether there are multiple nicknames
1818 or not. This configurable formatting was employed to flexibly
1819 support accessing multiple nicknames from the user interface.
1820 The userinterface can now set the nicknames to what ever format
1821 they prefer. Affected file lib/silcclient/silcapi.h.
1823 Added function silc_client_nickname_format to the file
1824 lib/silcclient/idlist.c. It performs the nickname formatting.
1826 Added new field `hostname´ to the SilcClientEntry context.
1827 It holds the hostname of the client. Affected file is
1828 lib/silcclient/idlist.h.
1830 * Irssi SILC Client sets the nicknames in nick@hostn format.
1831 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1832 irssi/src/silc/core/silc-core.c.
1834 The WHOIS printing now also shows both the real nickname and
1835 the formatted nickname so that user knows how to access the
1836 user if there are multiple same nicknames cached. Affected
1837 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1838 printing formatting too to take the hostname now as a separate
1839 argument. The Affected file is
1840 irssi/src/fe-common/silc/modules-formats.[ch].
1842 * Changed the silc_client_get_clients_local to accept the formatted
1843 nickname as argument. It accepts the real nickname too but the
1844 formatted nickname can be used to find the true entry from
1845 multiple entries. Affected file lib/silcclient/silcapi.h and
1846 lib/silcclient/idlist.c.
1848 * Added nickname_format_parse field to the SilcClientParams.
1849 It is a callback function provided by the application to parse
1850 the nickname out of the formatted nickname string. The library
1851 calls it to get the nickname from the formatted string. Since
1852 the application generally knows better the format of the nickname
1853 string it parses it instead of the library, even though library
1854 encodes the formatted string. If the callback function is not
1855 provided then the library will use the string as is. The
1856 affected file is lib/silcclient/silcapi.h.
1858 * All the nickname strings passed to the client library in
1859 commands are now expected to be formatted nickname strings.
1860 If the command does not support the formatted nickname string
1861 it will assume that the sent string is the actual nickname.
1862 Affected file lib/silcclient/command.c.
1864 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Added public key authentication support to OPER and SILCOPER
1867 commands in the client library. Affected file is
1868 lib/silcclient/command.c.
1870 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Changed the get_auth_methdod client operation to be asynchronous.
1873 It can be async if the application resolves the authentication
1874 method from the server during the negotiation. Added new
1875 SilcGetAuthMeth completion callback that the application will
1876 call after resolving the authentication method.
1878 Added function silc_client_request_authentication_method that
1879 the application can use to resolve the authentication method
1880 from the server. Added also SilcConnectionAuthRequest callback
1881 that the library will call after the server has replied. The
1882 application can call this function if it does not know the
1883 current authentication method.
1885 Affected files are lib/silcclient/client.c and
1886 lib/silcclient/silcapi.h.
1888 * The Irssi SILC client now automatically resolves the authentication
1889 method incase any configuration information is not present (and
1890 currently there never is). The affected file is
1891 irssi/src/silc/core/client_ops.c.
1893 * Fixed public key authentication from the client library.
1894 Affected file lib/silcclient/protocol.c. Changed also the
1895 protocol specification about the public key authentication in
1896 the connection authentication protocol. The actual data to be
1897 signed is now computed with a hash function before signing.
1899 * Fixed the public key authentication from the server as well.
1900 Affected file silcd/protocol.c.
1902 * Removed the mlock()'s from the memory allocation routines.
1903 Affected file lib/silcutil/silcmemory.c. The ./configure does
1904 not check anymore for the mlock(). Affected file is
1907 * Fixed USERS command in server to allow the execution of the
1908 command for private and secret channels if the client sending
1909 the command is on the channel. Affected file silcd/command.c.
1911 * Fixed silc_client_get_clients_local to return the clients
1912 count correctly. It could return wrong value. Affected file
1913 lib/silcclient/idlist.c.
1915 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1918 types. The assembler optimizations seemed not to like 64-bit
1919 data types. The assmebler optimizations thus are now enabled
1920 also for BSD systems as opposed to only enable them for Linux.
1922 * Do not check for threads at all on BSD systems. Affected
1923 file configure.in.pre.
1925 * Removed -n and -h options from the Irssi SILC Client since
1926 they are not used in silc.
1928 * Fixed the prime generation to assure that the first digit
1929 of the generated random number is not zero since our conversion
1930 routines does not like number strings that starts with zero
1931 digit. If zero digit is seen the random number is regenerated.
1932 This caused some corrupted RSA keys when the zero first digit
1933 was met. Affected file lib/silcmath/silcprimegen.c.
1935 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1937 * Fixed WIN32 configuration in the ./configure script.
1938 Fixed to include xti.h on environments that has it.
1939 Patches by Carsten Ilchmann and andrew.
1941 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Changed the silc_id_create_client_id to be collision
1944 resistant. It is now assured that there cannot be created
1945 two same client ID's. I suspect that some weird bugs in
1946 the server were actually caused by duplicate Client IDs.
1947 Affected file silcd/serverid.[ch]. A router receiving
1948 new ID now also assures and informs the sending server
1949 if the ID caused collision.
1951 * Changed the silc_id_create_channel_id to also assure that
1952 there are no collisions.
1954 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Statement about ignoring the Mutual Authentication flag when
1957 performing rekey with PFS was a bit misleading. It is ignored
1958 if it was set in the initial negotiation, it cannot be even
1959 set in the rekey. Fixed in the ke-auth draft. Started the
1960 new versions of the protocol drafts in the doc/.
1962 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Fixed a bug in silc_client_command_identify_save when saving
1965 new channel information. The channel name was no duplicated
1966 and caused crash on exit. Affected file is
1967 lib/silcclient/command_reply.c.
1969 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Fixed the getkey command handling in the server. Send just
1972 empty OK reply to the sender if the key could not be fetched
1973 (but everything else was ok, like the key just was not available).
1974 Changed the public key parameter to optional in the protocol
1975 specs so that empty OK reply can be sent. Affected file
1978 Added a message to Irssi SILC client to tell to user if the
1979 server did not return a public key.
1981 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Fixed a channel key regeneration bug. It registered new
1984 timeout tasks exponentially until all system resources were
1985 used. Affected file silcd/server.c.
1987 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * Added the SILC Document generator to the scripts/silcdoc.
1990 It can be used to generate the Toolkit Reference Manual out
1991 of the source tree. Internally it will also use the RoboDoc
1992 generator now imported in util/robodoc.
1994 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1996 * Added couple of return's in rekey protocol if error orccurred
1997 during the protocol. The execution must be terminated.
1998 Affected file silcd/protocol.c. Also, terminate the protocol
1999 always with timeout.
2001 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2003 * The client's Client ID was created initally from the wrong
2004 nickname (it could have been in format nick@host) in the
2005 silc_server_new_client. Affected file silcd/packet_receive.c
2007 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Added some SILC_LOG_ERROR's to various error conditions
2010 if client could not be added to ID cache. Affected files
2011 silcd/packet_receive.c and silcd/server.c.
2013 * When client's sock->user_data is freed, NULL also the
2014 client->router and client->connection pointers. Added check
2015 for these pointers being NULL to various places around the
2016 code. Affected file silcd/server.c.
2018 * Added client->data.registered == TRUE checks to various
2019 places around the code to assure that unregistered client's
2020 are not handled when it is not allowed. Affected file
2023 * Added `bool registered' fields to all
2024 silc_idlist_[server|client]_get_* routines to indicate whether
2025 the fetched client needs to be registered or not. Affected
2026 file silcd/idlist.[ch].
2028 * Add your own entry as registered to the ID cache in the
2029 server. Affected file server.c.
2031 * Fixed a bug in silc_server_new_server. The SilcServer was
2032 set as the new server's context instead of SilcServerEntry.
2033 This naturally caused some weird bugs.
2035 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Do not delete the channel rekey task when adding it
2038 for in silc_server_create_channel_key.
2040 * Changed the silc_server_create_channel_key to return
2041 TRUE or FALSE to indicate the success of the channel key
2044 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2046 * Fixed MSVC++ project files and added missing files to
2047 Makefiles under win32/.
2049 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Do not add TCP_NODELAY flag if the operating system
2052 does not have it defined. Affected files are
2053 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2055 * Fixed buffer overflow from Irssi SILC Client. Affected
2056 file irssi/src/fe-common/core/themes.c.
2058 * Fixed double free in client library in the file
2059 lib/silcclient/client.c when disconnecting from server.
2061 * Applied double free patch from cras to Irssi SILC client.
2062 Affected files irssi/src/core/[modules/expandos].c
2064 * Fixed the disconnection handling to Irssi SILC Client.
2065 The application must call silc_client_close_connection
2066 in ops->connect client operation in case of failure of
2067 the connection. Affected file is
2068 irssi/src/silc/core/client_ops.c.
2070 * Do not set sock->protocol to NULL in the function
2071 silc_client_close_connection after executing the protocol's
2072 final callback since the sock might not be valid anymore.
2073 Affected file lib/silcclient/client.c.
2075 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Do not enable SILC_THREADS if the linking with libpthread
2078 did not happen. Affected file configure.in.pre.
2080 * Added notion to protocol specification that server must
2081 verify the sent authentication payload with CMODE when
2082 setting the channel founder key. Implemented it to the
2083 server. Affected file silcd/command.c.
2085 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * Added _EXTRA_DIST SILC distribution variable to the
2088 distributions file. It is used to conditionally add extra
2089 files or directories to the specific distribution. Affected
2090 files ./prepare, Makefile.am.pre and distributions.
2092 Removed the `_' from the start of the distribution names.
2095 * Added README.WIN32 for instructions to compile the Toolkit
2098 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Fixed a double free in disconnection in the server. Affected
2101 file is silcd/server.c.
2103 * Fixed the lib/silcske/groups.c to work now also with GMP
2104 MP library. The string conversion did not work when using
2105 specific base and the base is indicated in the string as well.
2107 * Created win32/ directory which now includes MSVC++ specific
2108 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2109 It will appear only in the toolkit distribution
2111 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2113 * Changed the key material distribution function in case when
2114 the hash output is too short. The data is now concatenated
2115 a bit differently than it used to. Made the change to the
2116 SKE protocol specification.
2118 * Added better GMP detection to configure.in.pre. A patch
2121 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Fixed a minor bug in SKE that might cause some problem on
2124 some platforms. Affected file lib/silcske/silcske.c.
2126 * Added the cookie checking for initiator in the SKE. It checks
2127 that the responder returns the sent cookie unmodified. The
2128 affected file is lib/silcske/silcske.c. Added new SKE
2129 error type INVALID_COOKIE that can be sent during the
2130 negotiation. Fixed some memory leaks as well.
2132 * Added the "invalid cookie" error message to Irssi SILC client's
2135 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Added `task_max' field to the SilcClientParams to indicate
2138 the maximum tasks the scheduler can handle. If set to zero,
2139 default values are used. Affected file lib/silcclient/silcapi.h.
2141 * Fixed memory leaks in silc_client_close_connection. Affected
2142 file lib/silcclient/client.c.
2144 * Added silc_client_del_client_entry to client library to free
2145 all memory of given client entry. Affected file is
2146 lib/silcclient/idlist.[ch].
2148 * Added new functions silc_client_del_channel and
2149 silc_client_del_server to delete channel and server entries.
2150 Affected file lib/silcclient/[silcapi.h/idlist.c].
2152 * Removed silc_client_del_client_by_id from silcapi.h.
2154 * Fixed the INFO command to return the server's own info
2155 correctly when querying by Server ID. Affected file is
2158 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Removed the non-blocking settings in WIN32 code in the
2161 silc_sock_[read/write] and added SleepEx instead. Affected
2162 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2163 of input data is now checked with FIONREAD and ioctlsocket.
2165 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2167 * Call silc_schedule_task_del_by_context in the
2168 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2169 Affected file lib/silccore/silcprotocol.c.
2171 * Call silc_protocol_cancel for active protocols in the
2172 silc_server_close_connection if the funtion
2173 silc_server_free_sock_user_data has not been called.
2174 Affected file silcd/server.c.
2176 * Generic tasks cannot be deleted using the del_by_fd
2177 task deleting function since generic tasks does not match
2178 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2180 * Added a notion to SILCOPER help file that the SILCOPER works
2181 only on router server, not on normal server.
2183 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2185 * Added for WIN32 support for the new scheduler as well.
2186 Affected file lib/silcutil/win32/silcwin32schedule.c.
2188 * Fixed the SHA1 implementation to work on various platforms.
2190 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2193 API. It is part of the scheduler now. Everything else is
2194 as previously but some functions has changed their names.
2195 Checkout the lib/silcutil/silcschedule.h for the interface.
2196 Updated all applications to use the new interface. Affected
2197 files are lib/silcutil/silcschedule.[ch].
2199 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2201 * Found a bug in the SKE implementation. The HASH value,
2202 specified by the protocol, was not computed correctly. The
2203 public key of the responder was not added to the computation
2204 even though it is mandatory. Affected file lib/silcske/silcske.c.
2205 This unfortunately causes incompatibilities with older
2206 clients and servers.
2208 * Added WIN32 specific network init and uninit functions:
2209 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2210 the Winsock2. Affected file lib/silcutil/silcnet.h and
2211 lib/silcutil/win32/silcwin32net.c.
2213 * Set the socket always to nonblocking mode on WIN32 after
2214 reading data or writing data. Affected file is
2215 lib/silcutil/win32/silcwin32sockconn.c.
2217 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Fixed various compilation problems under WIN32. Affected
2220 files lib/silcutil/win32/silcwin32thread.c and
2221 lib/silcutil/win32/silcwin32schedule.c.
2223 * Removed all _internal.h #includes from public header
2224 files. Internal headers must never be included from
2227 Removed also the lib/silcske/payload_internal.h file.
2229 * All include files that may be needed (public and some others
2230 included by the public headers) by application developers are
2231 now copied to the ./includes directory. It does not copy any
2232 internal headers. Affected file Makefile.defines.pre and all
2233 Makefile.am's under lib/ and subdirs.
2235 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2237 * Do not change the ~/.silc directory's permissions automatically.
2238 Affected file irssi/src/silc/core/clientutil.c.
2240 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Do not cancel the protocol in silc_server_close_connection
2243 it might cause recursion. Now cancelled in the function
2244 silc_server_free_sock_user_data. Affected file silcd/server.c.
2246 * Fixed the silc_server_remove_clients_by_server to regenerate
2247 the channel keys correctly finally. Added also new function
2248 silc_server_remove_clients_channels to actually do it.
2249 Affected file silcd/server.c.
2251 * Fixed the silc_server_new_channel to not crash by giving
2252 wrong router to the new channel. Affected file is
2253 silcd/packet_receive.c.
2255 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2257 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2258 which is given as argument to the silc_client_alloc now.
2259 It can be used to configure the client and set various parameters
2260 that affect the function of the client.
2262 * The USERS command in server did not check whether the channel
2263 is private or secret. Affected file silcd/command.c.
2265 * Added new argument to the USERS command in protocol specification.
2266 The USERS command now can take the channel name as argument
2267 as well. Added support for this in client and server and
2268 updated the protocol specs.
2270 * Completed the GETKEY command in client. It can be now used
2271 to fetch also servers public key not only some clients.
2272 Affected files lib/silcclient/command[_reply].c.
2274 * Added silc_client_get_server to return server entry by the
2275 server name. Affected files lib/silcclient/silcapi.h and
2278 * Redefined the IDENTIFY command in protocol specification to be
2279 more generic. It now can be used to query information about
2280 any entity in the SILC Network, including clients, servers and
2281 channels. The query may be based either the entity's name
2282 or the ID. Added support for this in both client and server.
2284 Affected files silcd/command.c and lib/silcclient/command.c
2285 and command_reply.c.
2287 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2288 the _from_client and _from_server functions. Affected file
2291 * Added silc_client_get_channel_by_id_resolve to the file
2292 lib/silcclient/silcapi.h to resolve channel information by
2293 its ID. Added also silc_client_get_channel_by_id that
2294 does not resolve it from the server.
2296 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Added SilcServerEntry context into the client library
2299 to represent one server. The INFO command now allocates
2300 these to save the resolved server info. For now on the
2301 client library will also keep information about servers,
2302 connected and resolved with INFO.
2304 The INFO command now allocates the SilcServerEntry context
2305 and saves the server info there. The COMMAND_REPLY in
2306 the INFO now returns the parameters to application in
2307 same order as defined in the protocol specification.
2309 The entries are cached in the client->server_cache.
2311 * The INFO command is now issued after received the Client ID
2312 from the server. Affected file lib/silcclient/client.c.
2314 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2315 to the application as the mode changer might be server.
2316 It is guaranteed that NULL is not returned anymore to the
2317 application. Affected file lib/silcclient/client_notify.c.
2319 The ID Type is now also passed to the application so that
2320 it can check whether the returned entry is SilcClientEntry
2323 Added new function silc_client_get_server_by_id to return
2324 the server entry by ID. Affected files are the
2325 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2327 * Do not create the channel in the Irssi SILC Client when issuing
2328 the JOIN command but when received the sucessful JOIN command
2329 reply. Otherwise the channel might get created even though we
2330 could not join it. The Affected file is
2331 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2333 * Fixed a channel joining bug in router. The router must also
2334 check the channel modes, invite and ban lists etc. when serving
2335 the JOIN command sent by normal server. Affected file is
2336 silcd/command.c. The router now resolves the client's
2337 information from the server who sent the JOIN command if it
2338 does not know it, and processes the JOIN command only after
2341 * Changed the SilcCommandCb to take new argument; void *context2.
2342 Affected file lib/silccore/silccommand.h
2344 The second argument in the command callbacks in the server now
2345 includes the SilcServerCommandReplyContext if the command was
2346 called as pending command callback from the command reply.
2347 Otherwise it is NULL. When called as pending the status of the
2348 command reply will be checked and if it was erronous the
2349 error will be sent to the original sender of the command.
2350 This way the client always receives the error messages even
2351 though the server was actually the one who received the error
2352 when it resent the command to router, for example. Affected
2353 files silcd/command[_reply].[ch].
2355 * Fixed sending WHOWAS command's error message to client if
2356 the requested client could not be found. It was missing.
2359 * Changed the CMODE and CUMODE commands reply arguments in the
2360 protocol specification. The Channel ID is now sent in both
2361 of the commands to identify the channel. Implemented this
2362 new feature to the client and server. Affected files
2363 lib/silcclient/command_reply.c and silcd/command.c.
2365 * Made better checks for invite and ban lists in the JOIN
2366 command in server. Affected file silcd/command.c.
2368 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2370 * The server now performs the incoming host IP/DNS lookup
2371 using the silc_socket_host_lookup and thus does not block
2372 the server anymore. Affected file silcd/server.c.
2374 * Completed the multi-thread support for SILC Scheduler in
2375 the lib/silcutil/silcschedule.c.
2377 * Fixed the configure.in.pre to detect the pthread correctly
2380 * Fixed a deadlock in silc_task_queue_wakeup in the file
2381 lib/silcutil/silctask.c.
2383 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Added new function silc_schedule_wakeup that is used in
2386 multi-threaded environment to wakeup the main thread's
2387 schduler. It needs to be used when a thread adds a new task
2388 or removes a task from task queues. After waking up, the
2389 scheduler will detect the task queue changes. If threads
2390 support is not compiled in this function has no effect.
2391 Implemented the wakeup mechanism to both Unix and WIN32
2392 systems. Affected files are lib/silcutil/silcschedule.[ch],
2393 lib/silcutil/unix/silcunixschedule.c and the
2394 lib/silcutil/win32/silcwin32schedule.c.
2396 * Added new function silc_task_queue_wakeup to wakeup the
2397 scheduler by the specified task queue. Affected file
2398 lib/silcutil/silctask.[ch].
2400 * The silc_socket_host_lookup_start now wakes up the scheduler
2401 after adding the timeout task. Affected file is
2402 lib/silcutil/silcsockconn.c.
2404 * The silc_socket_host_lookup is synchronous now if the threads
2405 support is not compiled in. However, the callback is still
2406 called asyncronously through the scheduler, anyway. Affected
2407 file lib/silcutil/silcsockconn.c.
2409 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Added new function silc_socket_host_lookup to perform
2412 asynchronous IP and FQDN lookups for the socket connection.
2413 Affected files lib/silcutil/silcsockconn.[ch].
2415 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2418 that may or may not compile the mutex support in.
2420 Changed the silc_mutex_alloc interface. It allocates the
2421 mutex now to the sent pointer and returns TRUE or FALSE.
2423 Affected file lib/silcutil/silcmutex.h.
2425 * Wrote the SILC Task Queue interface to support multi-threads.
2426 Affected file lib/silcutil/silctask.[ch].
2428 * Wrote the SILC Scheduler to support multi-threads. Affected
2429 file lib/silcutil/silcschedule.c.
2431 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2433 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2434 in lib/silcutil/win32/.
2436 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2438 * Defined SILC Mutex API and SILC Thread API and implemented
2439 them for Unix. Affected files are
2440 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2441 lib/silcutil/unix/silcunixmutex.c and
2442 lib/silcutil/unix/silcunixthread.c.
2444 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Fixed the silc_server_remove_clients_by_server's channel
2447 key re-generation. The hash table handling was incorrect
2448 and would not work with many channels. Affected file is
2451 * Fixed some memory leaks around the server code.
2453 * Rewrote the silc_server_get_users_on_channel to support IPv6
2454 based Client ID's. Affected file silcd/server.c.
2456 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2457 specification. However, a separate document must be written
2458 to define the detailed signing procedure and the payload
2459 associated with the flag. Defined the flag to the
2460 lib/silccore/silcchannel.h as well.
2462 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Changed the dynamic tables to static size tables in the
2465 lib/silccrypt/silchmac.c.
2467 * Removed GCC dependencies from the code. A patch by cras.
2469 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Do not show the error "Error receiving packet bla bla"
2472 in server if it really was not an error (-2 means that reading
2473 is pending). Affected file silcd/server.c.
2475 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Fixed a possible crash in silc_server_remove_clients_by_server
2478 in silcd/server.c. Fixed there also some memory leaks.
2480 * Fixed the silc_idlist_replace_client_id. It could replace
2481 wrong key in the hash table. Affected file silcd/idlist.c.
2483 * Do not check whether there are global users on the channel
2484 if the channel->global_users is FALSE. Affected functions
2485 silc_server_remove_from_one_channel and
2486 silc_server_remove_from_channels in silcd/server.c. Also,
2487 do not check if the removed client is local as we can be
2488 sure that global client was not removed from the channel
2489 and checking for global users is not needed.
2491 * The silc_server_remove_clients_by_server now re-generates
2492 the channel keys correctly for those channels that had
2493 clients removed from them. Affected file silcd/server.c.
2495 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Found the reason of random crashes in the server. We weren't
2498 ignoring the SIGPIPE signal (which can be sent in write())
2499 and it crashed the server. Affected file silcd/silcd.c.
2501 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Assure that sock->user_data is not NULL in the function
2504 silc_server_packet_send in silcd/packet_send.c.
2506 * Disconnect the remote connection if it could not be added
2507 to any ID lists in the server. The affected file is
2510 * Check in silc_server_packet_send[_real/dest] that the
2511 socket is not disconnecting and ignore the data if it is.
2512 Affected file silcd/packet_send.c.
2514 * Define inline to __inline on native WIN32 compilation.
2515 Affected file includes/silcwin32.h.
2517 * Added some explicit type casts for inline code since MSVC
2518 require them. Affected files lib/silcutil/silcbuffer.h,
2519 lib/trq/silcdlist.h and lib/trq/silclist.h.
2521 * Print warning in log files from now on if the packet
2522 decryption fails. Affected file silcd/server.c.
2524 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Changed the `say' client operation's interface to accept
2527 new `type' argument to indicate the type of the message sent
2528 by the library. The application may filter the library's
2529 messages according the type. The affected file is the
2530 lib/silcclient/silcapi.h.
2532 * Added two new functions to lib/silcclient/silcapi.h:
2533 silc_client_del_client and silc_client_del_client_by_id.
2534 Affected file lib/silcclient/idlist.c.
2536 * Moved the clientincludes.h from includes/ to silc/ and
2537 serverincludes.h from includes/ to silcd/.
2539 * The modes for the CMODE and CUMODE are now passed as
2540 uint32 for application with COMMAND_REPLY. The affected
2541 file is lib/silcclient/command_reply.c.
2543 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * /WHOIS without arguments shows client's own information.
2546 Affected file lib/silcclient/command.c.
2548 * Changed PING to not accept any arguments. The specs
2549 says that client can ping only the connected server so
2550 requiring an argument is not needed. Affected file is
2551 lib/silcclient/command.c.
2553 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2555 * Fixed a fatal bug in private message sending and reception
2556 encryption and decryption when using private message keys.
2557 The implementation was incorrect and did not follow the
2558 specification. It causd that some of the message were
2559 lost since it did not use the sending and receiving keys
2560 as the protocol suggests. This has been fixed and will cause
2561 incompatibilities with older clients when sending private
2562 message encrypted with private message keys. Affected files
2563 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2564 and various other in Irssi SILC Client.
2566 Added `responder' boolean argument to the functions
2567 silc_client_add_private_message_key[_ske] to indicate when
2568 the key is added as responder or initiator of the key
2571 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Removed the silc_ske_check_version function and created
2574 a SilcSKECheckVersion callback. Added also a function
2575 silc_ske_set_callbacks that is now used to set all SKE
2576 callbacks. The callback functions are not given to
2577 the SKE functions anymore, but this function is used to
2580 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2582 * Added `silc_version' argument to the silc_client_alloc
2583 to define the version of the application for the library.
2584 The library will use the version string to compare it
2585 against the remote host's (usually a server) version
2586 string. Affected file lib/silcclient/silcapi.h
2588 * Added the KE protocol context to Key Agreement context
2589 in client library so that we can abort the SKE if it
2590 is in process when we get timeout. Affected file is
2591 lib/silcclient/client_keyagr.c.
2593 * Do not resolve the client ID forever if it returns in the
2594 first time that such client does not exist. This was done
2595 for example with private message. Affected file is
2596 lib/silcclient/client_prvmsg.c.
2598 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * Do not add regex.h for WIN32. The affected file
2601 includes/silcincludes.h.
2603 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2604 not work yet 100%. It generates the DLL's automatically
2605 when compiling with --with-win32 under cygwin.
2607 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * lib/contrib/regex.c is not compiled on WIN32.
2611 * Added silc_net_get_socket_opt function to the
2612 lib/silcutil/silcnet.h.
2614 * Added includes/silcwin32.h for WIN32 specific includes
2617 * Do not use ptime structure or any of the posix process
2618 functions on WIN32 in lib/silccrypt/silrng.c.
2620 * Added silc_gettimeofday to provide generic function
2621 for struct timeval on all platforms. Added the function
2622 to lib/silcutil/silcutil.h.
2624 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2627 library as they clearly belong there. As a plus side we
2628 can make the actual socket connection routines platform
2631 Added also new generic function silc_socket_read and
2632 silc_socket_write (that used to be silc_packet_[read/write].
2633 The implementation of these are platform specific.
2635 * Added WIN32 specific routines of silc_socket_[read/write]
2636 to lib/silcutil/win32/silcwin32sockconn.c.
2638 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Added preliminary support for native WIN32 compilation under
2641 cygwin (using the -mno-cygwin option for GCC) to the
2642 ./configure.in.pre. The --with-win32 now prepares the
2643 compilation for native WIN32.
2645 * Rewrote the SILC Scheduler interface in the file
2646 lib/silcutil/silcschedule.h. The scheduler is now context
2647 based and does not have anymore any global static scheduler.
2648 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2649 and created lib/silcutil/win32 directory for WIN32 based
2652 * Added Unix specific network routines to the
2653 lib/silcutil/unix/silcunixnet.c and the old
2654 lib/silcutil/silcnet.c includes now only generic routines.
2656 Added WIN32 specific network routines to the
2657 lib/silcutil/win32/silcwin32net.c.
2659 * Added Unix specific utility functions from the
2660 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2662 * Added WIN32 SILC Scheduler to the file
2663 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2666 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Do not handle JOIN notify in the server if the target client
2669 is not registered (idata->registered == FALSE). The affected
2670 file is silcd/packet_receive.c.
2672 * Update the nickrec->founder in event_cumode in the Irssi SILC
2673 client. Affected file irssi/src/silc/core/silc-channels.c.
2675 * Fixed the CUMODE_CHANGE notify handling in the server when
2676 server and router are announcing their clients on channels.
2677 Now the mode changes are saved and notified correctly. The
2678 affected file is /silcd/packet_receive.c.
2680 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2681 They really did not replace the cache entry in the ID Cache.
2682 Now they do that. Affected file silcd/idlist.c.
2684 * Fixed the KICK notify handling in the Irssi SILC client to
2685 update the channel records so that the kicked client does not
2686 appear to be on the channel. The affected file is
2687 irssi/src/silc/core/silc-channels.c.
2689 * Always update the conn->current_channel when executing command
2690 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2692 * Fixed the KILL notify handling in Irssi SILC client to remove
2693 the killed client on all channels.
2695 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2697 * Fixed the silc_parse_command_line to remove extra spaces
2698 from the start and end of the arguments. Affected file is
2699 lib/silcutil/silcutil.c.
2701 * Cancel and free any active protocol in the function
2702 silc_server_close_connection. Affected file silcd/server.c.
2704 * Cancel and free any active protocol in the function
2705 silc_client_close_connction. Affected file is
2706 lib/silcclient/client.c.
2708 * Do not execute the KILL command for clients that are in
2709 history (ie. they are not in the network). Affected file is
2712 * Fixed KILL notify handling, client does not crash anymore.
2713 Affected file irssi/src/silc/core/silc-channels.c.
2715 * Reduced the default packet buffer size from 2048 to 1024 in
2716 lib/silccore/silcpacket.c.
2718 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2719 counter to the SKE context that is incresed when the SKE library
2720 performs async operation outside the library. If the outside
2721 process frees the SKE context and FREED status will be set
2722 and the library will detect after the sync operation that the
2723 libary is freed. The affected files are
2724 lib/silcske/silcske[_status].[ch].
2726 * Resolve the client entry information in the function
2727 silc_client_channel_message to assure that NULL pointer is not
2728 passed as client entry to the application. */
2730 * Fixed the task timeout calculation to assure that there is
2731 never negative timeouts. The affected file is
2732 lib/silcutil/silcschedule.c.
2734 * Fixed the channel user mode notification sending in server.
2735 It was sent point-to-point to the router (or to server by router)
2736 but it needs to be destined to a channel. The routines now
2737 supports sending the channel user mode notifys to the channels
2738 when announcing clients and channels. Affected files are
2739 silcd/server.c and silcd/packet_receive.c.
2741 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2742 It did not actually replace the old channel entry in the cache.
2743 Affected file lib/silcclient/client_notify.c.
2745 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2747 * Fixed a possible crash in silc_packet_send_prepare. It now
2748 assures always that there is enough space in the buffer and
2749 at the tail area of the buffer (for MAC).
2751 Fixed the inbound buffer reallocation in silc_packet_read.
2752 It was old code and did not handle the reallocation correctly.
2755 The affected file is lib/silccore/silcpacket.c.
2757 * Fixed buffer overflow in silc_parse_nickname in the file
2758 lib/silcutil/silcutil.c.
2760 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2762 * make install generates new server keys only if there is not
2765 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2768 Added check that if the NOREPLY is set then we will not send
2769 the away message. This avoids infinite loop of away messages
2770 if both clients are away. The affected file is
2771 lib/silcclient/client_prvmsg.c.
2773 * Fixed client crash if /NICK was given without arguments.
2774 Affected file lib/silcclient/command.c.
2776 * Server does not send the invite list in INVITE command back
2777 to the client if the list was not altered. Added this notion
2778 to the protocol spec as well. Affected file silcd/command.c.
2780 Fixed possible crash in INVITE command by checking the
2781 value of silc_server_get_client_route command.
2783 * Fixed the INVITE notify type handling. The arguments are now
2784 taken in correct order and client does not crash. The affected
2785 file is irssi/src/silc/core/silc-channels.c.
2787 Removed the "Inviting xxx to channel" message from the
2788 client library away and let the application handle it.
2789 Affected file lib/silcclient/command.c. Added that message
2790 to Irssi SILC client's message formats.
2792 * Fixed CMODE command crash in client. It now checks the
2793 amount of arguments correctly and does not crash. The affected
2794 file is lib/silcclient/command.c.
2796 * Do not create new channel automatically in silc_channels_join
2797 but check whether the channel by that name already exists.
2798 Affected file irssi/silc/core/silc-channels.c.
2800 * Do not send the SERVER_SIGNOFF to router if the disconnected
2801 entity was the router. Affected file silcd/server.c.
2803 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2804 SILC client as it was missing from there.
2806 Added the handling of the KICK notify to the Irssi SILC client
2807 as it was missing. Added "you have been kicked" message to
2808 Irssi SILC client's message modules formats.
2810 Added the handing of the KILL notify to the Irssi SILC client
2811 as it was missing. Added the kill message module formats
2814 The affected file is irssi/src/silc/core/silc-channels.c.
2816 * The router did not save the channel mode the server announced.
2817 Affected file silcd/packet_receive.c.
2819 * Fixed a possible crash in INFO command in server. If the
2820 server did not provide the server info it crashed. Affected
2821 file silcd/command.c.
2823 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2825 * Fixed the GETKEY command in the server to check also the
2826 global list. Otherwise the GETKEY would not work correctly
2827 in normal SILC server. Affected file silcd/command.c.
2829 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2831 * Fixed GETKEY crash, it crashed if the command did not succseed.
2833 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2835 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2836 is now real and not just an macro interface to GMP.
2838 Removed the entire GMP from the source tree and imported new
2839 NSS MPI library instead. Reason for removing GMP is that it is
2840 extremely large and compiles extremely slow. The NSS MPI
2841 is only a few files and compiles in less than 10 seconds.
2842 The speed is also about the same as GMP. The MPI is imported
2843 to lib/silcmath/mpi.
2845 If the system has GMP installed we will still use the GMP.
2846 If it is not then the NSS MPI will be compiled.
2848 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2850 * Merged a long nickname (127 characters long) crash bugfix from
2851 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2853 * Merged a freed memory reference bugfix from Irssi CVS tree.
2854 Affected file irssi/src/core/commands.c.
2856 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2858 * Added the server's public key sving and verification to the
2859 server when performing the SKE. This was missing and the
2860 remote server's (or router's) public key was accepted without
2861 checking whether we have it previously or trust it at all.
2862 Affected file silcd/protocol.c.
2864 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Check in the silc_server_timeout_remote if protocol is active
2867 and make sure that the protocol's final callback is called so
2868 that all memory if freed. Affected file silcd/server.c.
2870 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * silc_server_whois_send_reply crashed the server if the nickname
2873 was 127 characters long. Affected file silcd/command.c.
2875 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2877 * Added sanity check to the silc_server_new_client. If the hostname
2878 is provided inside username then check that the provided hostname
2879 really is the same as the resolved one. If the hostname was not
2880 resolved then check it from the public key. Affected file is
2881 silcd/packet_receive.c.
2883 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2884 if the server disconnected us and the connection is not valid
2885 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2887 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2888 the library to the lib/silcutil/silcutil.[ch].
2890 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2892 * Close log file after open. Affected file
2893 lib/silcutil/silclog.c.
2895 * Check whether sock == NULL in silc_client_send_packet and return
2896 if it is. Affected file lib/silcclient/silcclient.c.
2898 * Check rec->entry == NULL in the Irssi SILC Client before
2899 sending the channel message. Affecte file is
2900 irssi/src/silc/core/silc-servers.c.
2902 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Merged a splitted window bugfix from Irssi CVS tree. The
2905 affected file is irssi/src/fe-text/textbuffer-view.c.
2907 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2908 It did not print nickname.
2910 * Improved the distributions system a bit.
2912 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2915 irssi/src/fe-text/gui-window.c.
2917 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2918 to in-active server. The affected file is
2919 irssi/src/silc/core/client_ops.c.
2921 * Resolve the client in USERS command reply if the entry does
2922 not have username resolved. The affected file is
2923 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2924 command to WHOIS command to really resolve stuff. The USERS
2925 is not used any more in any critical section so WHOIS can
2926 be used even though it might be slower than IDENTIFY.
2928 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2931 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2933 * Changed the protocol API a bit more consistent in the
2934 lib/silccore/silcprotocol.[ch].
2936 * Changed the following headers to ROBODoc format:
2938 lib/silccore/silcpayload.h
2939 lib/silccore/silcprotocol.h
2940 lib/silccore/silcsockconn.h
2942 All core library headers are now formatted.
2944 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Fixed a bug in Irssi SILC client; do not show that you are
2947 server/router operator if you really are not. Affected file is
2948 irssi/src/silc/core/client_ops.c.
2950 * Renamed silc_command_free_payload to silc_command_payload_free.
2951 Affected file lib/silccore/silccommand.h
2953 * Added silcmath.h to include the prototoypes of various routines
2954 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2957 * Changed the following headers to ROBODoc format:
2959 lib/silccore/silcchannel.h
2960 lib/silccore/silccommand.h
2961 lib/silccore/silcid.h
2962 lib/silccore/silcidcache.h
2963 lib/silccore/silcmode.h
2964 lib/silccore/silcnotify.h
2965 lib/silccore/silcpacket.h
2966 lib/silcmath/silcmath.h
2968 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2970 * Added checking to the server code not to start the server if
2971 ciphers and stuff are not configured properly. Affected files
2972 silcd/serverconfig.[h] and silcd/server.c.
2974 * Changed the layout of the header files of the public interfaces
2975 in the SILC libraries. The new layout supports ROBODoc
2976 documentation tool (and some others) so that it is easy to create
2977 a library reference manual. All the other headers and source
2978 code must still follow the CodingStyle document. Also source
2979 code must not include these ROBODoc stuffs, only the headers.
2980 Furthermore, all public interface headers must now be named
2981 by using `silc' prefix, example: silcapi.h, silccipher.h.
2982 Some files were renamed due to this. All the other headers
2983 must not be used as public interfaces. I will update the
2984 CodingStyle document later. Changed following headers, so far:
2986 lib/silcclient/silcapi.h
2987 lib/silccore/silcauth.h
2988 lib/silccore/silcprivate.h
2989 lib/silccrypt/silcdh.h
2991 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Removed silc_client_packet_send_flush from the client library
2996 as it is not needed. Affected file lib/silcclient/client.[ch].
2998 * Added printing of message of unresolved authentication method
2999 to the Irssi SILC client. Added it to the module formats.
3000 Removed the same message from the client library.
3002 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3004 * Added new distribution feature, DISTLABEL. Every distribution
3005 can define own preprocessor label that can be used in the
3006 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3007 file distributions, acconfig.h.pre and prepare.
3009 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3011 * Added Makefile.defines_int to include the actual definitions
3012 for Makefile.defines.in. Tested the new distribution system,
3013 created distributions and tested installation.
3015 * Added AWAY message printing to the Irssi SILC client. Added
3016 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3018 * Added SCONNECT command to call the SILC's CONNECT command.
3019 Cannot use CONNECT directly since Irssi uses that internally.
3020 Affected file irssi/src/silc/core/silc-servers.c.
3022 Added ACTION local command. It is same as ME command but takes
3023 the channel as mandatory argument.
3025 Rewrote some of the Irssi's help files to suite for SILC
3028 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3030 * Added Makefile.defines[.in] that should for now on be included
3031 in all Makefile.am file in the source tree. That file includes
3032 all common compilation definitions for SILC source tree.
3034 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3036 * Minor changes to the ./prepare script to change the package
3037 name according the distribution name to the configure.in.
3039 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Created new distribution system. Added file `distributions'
3042 that defines all the distributions that can be created out of
3043 the SILC source tree. The ./prepare script now reads that
3044 file to determine how to prepare the distributions. The
3045 first argument to the ./prepare is the name of the distribution
3046 and second is the version of the distribution. If given
3047 without arguments it creates the default (toolkit) distribution
3048 with the default version (defined in ./prepare).
3050 All Makefile.am files that are subject to the distributions
3051 are now named as Makefile.am.pre. These are ./Makefile.am
3052 and lib/Makefile.am. Others may be changed later.
3054 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3056 * Added invite list, ban list, some key management and connection
3057 error message printing to module formats in the Irssi SILC client.
3059 * Added new silc_client_set_away_message to set the away message
3060 that is back to the person who sent private message. The
3061 affected file lib/silcclient/silcapi.h and the
3062 lib/silcclient/client_prvmsg.c.
3064 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Fixed the private message sending in the Irssi SILC client,
3067 added local command KEY to the Irssi SILC client.
3069 Added key management and key agreement message formats to the
3070 irssi/src/fe-common/silc/module-formats.[ch].
3072 Added USERS (alias WHO) printing, server/router operator
3073 indication and LIST command printing to the module formats.
3075 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Fixed channel joining notify handling, cumode notify handling
3078 from Irssi SILC client.
3080 * Added SILC specific module-formats to the Irssi SILC client so
3081 that SILC specific message hilighting, colors etc is possible.
3082 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3084 Added channel mode, channel user mode, actions, notices,
3085 whois and whowas printing to the the module-formats.c.
3087 * Fixed a bug in channel deletion in the server. The channel
3088 is not left to the cache even if the channel founder auth mode
3089 is set when there are no users anymore on the channel. Affected
3090 file silcd/server.c.
3092 * The silc_net_localhost now resolves the entire hostname including
3093 the domain name. Affected file lib/silcutil/silcnet.c.
3095 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Changed the ask_passphrase client operation to be ascynchronous.
3098 It has now a completion callback and a context that the
3099 application must call after it has got the passphrase from
3100 the user. Affected files lib/silcclient/silcapi.h,
3101 lib/silcclient/protocol.c, lib/silcclient/command.c and
3104 Added SilcAskPassphrase callback that the application calls
3105 to deliver the passphrase to the library.
3107 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3108 The public key verification and especially a certificate
3109 verification is asynchronous procedure.
3111 Added new SILC_SKE_STATUS_PENDING status to indicate the
3112 request is pending and a callback will be called to finalize
3115 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3116 indicate that remote end did not send its public key (or
3117 certificate), even though we require it. Added check for this
3118 condition in the SKE. This was a security bug, now fixed.
3120 Defined new SilcSKEVerifyCbCompletion callback that is called
3121 when the verification process is completed.
3123 The affected files lib/silcske/silcske_status.h and
3124 lib/silcske/silcske.[ch].
3126 * Changed the verify_public_key client operation to be async
3127 as well. Defined SilcVerifyPublicKey callback that is used to
3128 indicate the success of the public key verification process.
3130 Changed the server and client to use the new async client
3133 * Changed the Irssi SILC client's internal scheduler to be called
3134 twice as many times as it used to be. As a result the client
3135 should be a bit faster now. Affected file is
3136 irssi/src/silc/core/silc-core.c.
3138 * Added support to Irssi SILC client of asynchronous public key
3139 verification and passphrase inquiry. Affected file is
3140 irssi/src/silc/core/silc-core.c.
3142 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3144 * Do not say "You have left channel %s" in client library.
3145 Moved it to the application. Affected files are
3146 lib/silcclient/command.c and silc/client_ops.c.
3148 * Fixed silc_client_get_clients. Command context was not
3149 duplicated and was freed memory in the callback. Affected
3150 file lib/silcclient/idlist.c.
3152 * Do not say "you are now talking..." on JOIN command in the
3153 client library. The appliation must handle it.
3155 * Do not say ".. changed topic to" in command reply in the
3156 client libary. The application must handle it.
3158 * Fixed TOPIC command sending in the client library.
3160 * Fixed a memory leak in silc_client_command_free in the file
3161 lib/silcclient/command.c.
3163 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3165 * Imported a modified version of Irssi client to the source tree.
3166 The Irssi will be used to create a new client called
3167 Irssi SILC. Imported to irssi/.
3169 Added silc_core_init_finish function to the Irssi. Affected
3170 file irssi/configure.in.
3172 A lot changes in the Makefile.ams around the irssi tree.
3174 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Do not rehash if the new size is same as the old size of the
3177 hash table, in the silc_hash_table_rehash*. The affected file
3178 lib/silcutil/silchashtable.c.
3180 * Replaced hash_table_del_by_context calls from the server
3181 (when channel->user_list and client->channels) to the
3182 hash_table_del as it is sufficient and faster.
3184 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Added silc_hash_table_list, silc_hash_table_get and the
3187 SilcHashTableList structure to provide an alternative way to
3188 traverse the hash table. The affected files are
3189 lib/silcutil/silchashtable.[ch].
3191 * Changed the server's idlist routines to use the hash table
3192 routines to optimize the code.
3194 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Replaced the client entry's `channel' list and channel entry's
3197 `user_list' list to hash tables for optimized lookup. Changed
3198 the code to use the hash table interface around the code.
3199 Affected file lib/silcd/idlist.[ch].
3201 * Added `auto_rehash' boolean argument to the function
3202 silc_hash_table_alloc to indicate whether the hash table should
3203 auto-rehash when it thinks is appropriate time. It will
3204 increase the hash table size if the there is twice as much
3205 entries in the table than the size of the table, and will
3206 decrease the size if there are twice as less entries than
3207 the size of the table.
3209 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3213 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * silc_idcache_purge_by_context deletes the entry now by context
3216 as it is supposed to do. Affected file lib/silccore/idcache.c.
3218 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3219 client is not anymore valid (WHOWAS givens the info) and not
3220 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3222 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Removed the `data' and `data_len' arguments from the ID Cache
3225 interfaces and added `name' argument. ID Cache does not handle
3226 anymore the binary data only a names associated with given ID.
3228 * When hashing a Client ID with silc_hash_id the entire ID is
3229 not hashed anymore, instead only the hash of the Client ID is
3230 hashed. This way we can access the Client ID from the cache
3231 with Client ID but with the hash of the ID (which is a hash of
3232 the nickname) as well without any difference in performance.
3234 Added also silc_idcache_find_by_id_one_ext to do one on one
3235 searching when we have the actual ID. Added also function
3236 silc_hash_client_id_compare. The affected files are
3237 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3239 * When hashing the name associated with a ID it is always done
3240 in lowercase. This way we can access the cache without worrying
3241 about case-sensitivity, even though, for example nicknames are
3244 * Fixed a bug in server with channel message sending. It put
3245 wrong ID type as destination ID. The affected file
3246 silcd/packet_send.c.
3248 * silc_idcache_del_by_context now deletes from all hash tables
3249 by context. Affected file lib/silccore/idcache.c.
3251 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Changed the client library to use the new ID Cache interface.
3254 Changes around the source tree.
3256 * Added silc_hash_table_rehash_ext to rehash with specific
3257 hash function. Affected file lib/silcutil/silchashtable.[ch].
3259 * Added silc_hash_string_compare to compare two strings in the
3260 hash table. Affected file lib/silcutil/silcutil.[ch].
3262 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * Added new function silc_idcache_del_by_context into the
3265 lib/silccore/idcache.[ch].
3267 * Changed the server's ID list routines to use the new ID Cache
3268 interface. Changes around the source tree.
3270 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Added silc_hash_table_del[_by_context]_ext functions in to the
3273 lib/silcutil/silchashtable.[ch].
3275 Removed silc_hash_table_find_all* routines and added new
3276 silc_hash_table_find_foreach to replace them.
3278 Added silc_hash_table_replace_ext function as extended
3279 replacing function. Separated the simple hash table interface
3280 from the extended hash table interface in the file
3281 lib/silcutil/silchashtable.h.
3283 * Fixed minor bugs and changed it to use some of the new
3284 hash table functions in lib/silccore/idcache.c
3286 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Added new function silc_hash_table_find_all to return all keys
3289 in the hash table by the specified key. As the hash table is
3290 collision resistant it also makes it possible to have several
3291 duplicate keys in the hash table. This function may be used to
3292 find all of the keys from the hash.
3294 Added user_context arguments to the SilcHashFunction,
3295 SilcHashCompare and SilcHashDestructor to deliver user specified
3298 Added new fuctions silc_hash_table_find[_all]_ext to do
3299 extended lookup with specified hash and compare functions and
3300 specified user contexts.
3302 Added new function silc_hash_table_add_ext to add the key
3303 with specified hash function and user context.
3305 Added new function silc_hash_table_foreach to traverse all
3306 entrys in the hash table. Added SilcHashForeach callback
3309 Added new function silc_hash_table_del_by_context to delete
3310 the entry only if the context associated with the key matches.
3312 Affected files are lib/silcutil/silchashtable.[ch].
3314 * Removed silc_hash_[server/client/channel]_id and added just
3315 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3316 silc_hash_id_compare to compare two ID's using as the hash table
3317 comparison function. Added also silc_hash_data to hash
3318 binary data and silc_hash_data_compare to compare it.
3320 * Removed silc_idlist_find_client_by_hash as it is not needed
3321 anymore. Affected file silcd/idlist.[ch].
3323 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3324 to use internally the SilcHashTable. The new ID Cache is a lot
3325 faster than the old one. Some of the ID Cache interface was also
3326 rewritten and obsolete and stupid functions were removed.
3328 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Added entry_count field to the SilcHashTable to keep the number
3331 of the entries in the table. Implemented the function
3332 silc_hash_table_rehash. Added new function
3333 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3335 Fixed a minor bug in silc_hash_table_free.
3337 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3338 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3339 into the lib/silcutil/silcutil.[ch].
3341 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3343 * Implemented a collision resistant hash table into the
3344 lib/silcutil/silchashtable[ch]. See the header and the source
3345 for the SilcHashTable API.
3347 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Merged dotconf version 1.0.2 into lib/dotconf.
3351 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Do not compile anything in lib/silcsim/* if the SIM support
3354 is not enabled. The tree should now compile without problems
3357 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Compiled the SILC under cygwin. Compiled and tested briefly
3360 without problems. More tests needed. The SIMs didn't compile
3363 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3365 * Fixed possible crash in silc_get_username in the
3366 lib/silcutil/silcutil.c.
3368 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Fixed a va_arg in silc/client_ops.c.
3372 * Oops, RC5 routines were named AES and caused some problems
3373 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3375 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Added new SilcIDIP structure into the lib/silccore/id.h and
3378 replaced the old `ip' fields from all SILC ID's to that type.
3379 This is a step towards IPv6 support.
3381 The silc_id_get_len takes now the ID as an extra argument.
3382 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3383 both IPv4 and IPv6 based ID's.
3385 The affected files are lib/silccore/id.[ch] and other files
3386 around the tree using these routines.
3388 * Removed the ID length arguments in server from various
3389 silc_server_send_notify_* routines -> they are not needed
3392 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3394 * Fixed memory leak in silc_encode_pem_file in the file
3395 lib/silcutil/silcutil.c.
3397 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3399 * Check minor version as well in the SKE. Affected files are
3400 silcd/protocol.c and lib/silcclient/protocol.c.
3402 * Added --identifier option to the server so that an identifier
3403 can be when creating the public key for the server. Affected
3404 file is silcd/silcd.c.
3406 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3407 lib/silccrypt/silcpkcs.c.
3409 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3411 * Register default ciphers and stuff when using -C option with
3412 the server. Affected file sildc/silcd.c.
3414 * Put back the servers public key filename format, it is better
3415 than the new one. For now, the client keys are saved with the
3416 new filename format. The affected file silc/client_ops.c.
3418 * Implemented the Cipher API for the rest of the ciphers that
3419 did not implement it or implemented it the wrong way.
3421 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Register default ciphers and stuff when using the -S option
3424 in the client. Affected file silc/silc.c. Same also when
3425 creating new key pair with -C option.
3427 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Fixed the silc_verify_public_key client operation function to
3430 save the public keys differently. The fingerprint is now
3431 used as filename and not the hostname. This way also the
3432 client keys are saved uniquely and not with hostnames. The
3433 affected file is silc/client_ops.c.
3435 * Trimmed the silc_hash_fingerprint function to remove extra
3436 whitespaces from the end of the fingerprint. The affected
3437 file is lib/silccrypt/silchash.c.
3441 * Added silc_cipher_register_default function to register all
3442 default ciphers. It can be used when configuration files
3443 does not exist and the application does not want any specific
3444 ciphers in any specific order.
3446 The SilcDList is now used as silc_cipher_list dynamically
3447 allocated cipher list. Removed the static list all together
3448 and now all ciphers must be allocated to the dynamic list.
3449 The silc_cipher_alloc routine was changed to check only the
3452 All silc_cipher_* routines that used to return int returns
3455 The affected files lib/silccrypt/silccrypt.[ch].
3457 * The same thing was done to silc_hash_* as for silc_cipher_*
3458 routines. Affected files lib/silccrypt/silchash.[ch].
3460 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3461 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3462 Added also silc_pkcs_[un]register[_default] functions.
3463 Removed the data_context from the PKCS API.
3465 * Added silc_hmac_register_default function to register default
3466 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3467 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3468 to unregister all hmacs at once.
3470 * Register the default ciphers, hash functions, PKCSs and HMACs
3471 if client's configuration file does not exist. The affected
3474 * The client did not load the hash functions from the SIM
3475 modules at all. Added support for this. Affected file is
3476 silc/clientconfig.c.
3478 * When decoding public key with silc_pkcs_public_key_decode, check
3479 the supported algorithm only if PKCS are registered. Affected
3480 file lib/silccrypt/silcpkcs.c. The same was done with the
3481 silc_pkcs_private_key_decode.
3483 * Fixed the SILC List routines to keep the list always in order.
3484 It used to change the list's order when traversing the list but
3485 not it preserves the order. Affected file lib/trq/silclist.h.
3487 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3489 * Added the client library to use the SilcSocketConnection's
3490 reference counter (by silc_socket_dup) to prevent the bug that
3491 the socket object may be freed underneath async operation.
3493 * The name resolv library checking fixes in the configure.in.pre.
3496 * Created new version of the protocol drafts for future
3497 development. The -03 drafts are the ones that will be changed
3498 in the trunk now and the -02 will remain as they are.
3500 * Send list of CUMODE notifys to the router when announcing
3501 the channel users to the router. Affected file silcd/server.c.
3502 If the router receiving channel founder CUMODE for a channel
3503 that already has channel founder it will send CUMODE notify
3504 to the sender to remove the channel founder rights from the
3505 announced client. Affected file silcd/packet_receive.c.
3507 * The CUMODE notify may now use Server ID as well as the entity
3508 who changes the mode. Updated protocool specs.
3510 * Updated INSTALL and README files.
3512 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * New web pages in the http://silc.pspt.fi. The pages was
3519 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Implemented the [DenyConnectin] config section in the server.
3522 Added silc_server_config_denied_conn to check whether incoming
3523 connection is denied. Affected file silcd/serverconfig.[ch].
3525 * Do not check the ports when checking the incoming configuration
3526 data if the port is 0, meaning any. Affected file is
3527 silcd/serverconfig.c.
3529 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3531 * Fixed buffer overflow in silc_string_compare in the file
3532 lib/silcutil/silcutil.c.
3534 * Fixed double free in silc_server_command_leave in the file
3537 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Fixed the version checking in the server. Affected file is
3542 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3544 * Fixed the configuration data fetching when accepting new
3545 connections in the server. Affected file silcd/server.c.
3547 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Added `sender_entry' argument to the function
3550 silc_server_packet_relay_to_channel so that we can check
3551 whether some destination actually belongs to the same route
3552 the sender belongs (ie, we must not resend the packet to the
3553 sender). Affected file silcd/packet_send.[ch].
3555 * Added `servername' field to the SilcClientEntry in the server
3556 to hold the name of the server where client is from. Affected
3557 file is silcd/idlist.h.
3559 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Moved the channel message encrypting in the router betwen
3562 router connections from silc_server_channel_message to the
3563 silc_server_packet_relay_to_channel since we want to check
3564 whether we have anybody channel before encrypting anything.
3565 Affected files silcd/packet_[receive/send].c.
3567 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Fixed the [AdminConnection] server config section to support
3570 multiple entries. Affected file silcd/serverconfig.c.
3572 * Added support into the server to check the validity of the
3573 incoming connection before executing any KE or authentication
3576 * The connection configuration is now saved to the KE and
3577 connection auth protocol contexts and not fetched anymore in
3578 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3580 * The local hosts listenning address and port is also resolved
3581 now when starting the server. We want to have the socket object
3582 to include the real address and port for the listener. Added
3583 new function silc_net_check_local_by_sock into the files
3584 lib/silcutil/silcnet.[ch].
3586 * Fixed a broadcast bug in server -> do not broadcast if we
3589 * Fixed a routing bug. Do not route broadcast packets ever.
3590 Broadcast packets must be processed always and not routed since
3591 they may be destined to some other host than yourself and thus
3592 would get routed without no good reason. Affected file is
3595 * Added function silc_server_config_is_primary_route to check
3596 whether primary router connection has been configured (a router
3597 configuration that we are initiating). If there is not, we
3598 will assume that there is only two routers in the SILC network
3599 and we will use the incoming router connection as our primary
3600 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3602 * Changed the order of the broadcasting. Broadcast _after_ the
3603 packet has been processed not before. Affected file is
3606 * Fixed a [ClientConnection] parsing bug. The port was never
3607 parsed correctly thus resulting to port 0. Affected file
3608 silcd/serverconfig.c.
3610 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3611 argument and did not set the broadcast packet flag. Affected
3612 file silcd/packet_send.c. Fixed same bug in the function
3613 silc_server_send_notify as well.
3615 * If we receive NEW_ID packet for our own ID in the server, ignore
3618 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3622 * Removed the nickname from the Private Message Payload.
3623 Updated the code and the protocol specs.
3625 * Updated protocol specs for submitting to the IETF.
3627 * Tweaked the Random Number Generator a bit. Affected file
3628 lib/silccrypt/silcrng.c. Exported a new function
3629 silc_rng_[global]_add_noise which can be used to add more
3632 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Do not parse packets with different timeout when protocol
3635 is active -> may cause problem with rekey. Affected file
3638 * When server receives signoff notify it must not create
3639 new channel key if the client is on any channels since the
3640 sender of the signoff notify will create it.
3642 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Added printing of error messages during SKE protocol from the
3645 failure packet sent by server during SKE. Affected file
3648 * Removed the client's failure_callback handling with timeout
3649 and handle it immediately when received.
3651 * The SKE library returned wrong type in SUCCESS and FAILURE
3652 packets. They must be 32 bit MSB not 16 bit MSB.
3654 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Ok, rewrote the logic of the re-key and now it seems to work.
3657 I tested it on high traffic with frequent re-keys without
3658 problems. Added hmac_receive (and renamed hmac to hmac_send)
3659 in SilcClientConnection in lib/silcclient/client.h and
3660 in SilcIDListData in silcd/idlist.h. Also, removed the
3661 SilcPacketParserContext's cipher and hmac fields as they are
3662 not needed anymore and actually caused some problems when
3663 the ciphers and hmac's changed underneath the packet parser.
3665 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * If re-key protocol is active then process the incoming packets
3668 synchronously since we must assure that icoming packets encrypted
3669 with the old key is processed before the new keys is set to
3670 use. This is true other packets than for REKEY packets.
3671 Affected file silcd/server.c. The same was done to client library
3672 as well, affected file lib/silcclient/client.c.
3674 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Fixed bug in client and server to accept the force send if
3677 the packet is send from silc_[server/client]_packet_process
3678 function. Otherwise the packets are never delivered, oops.
3680 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Disable force sending of packets when REKEY protocol is active.
3683 We must assure that no packet is sent directly when rekey is
3684 performed. All packets must be sent through packet queue.
3685 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3686 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3687 function is silc_[server/client]_packet_send_real to check
3690 * Replaced the SIM paths from example config files to
3691 /usr/local/modules. Also, make install creates now
3692 /usr/local/silc/logs directory to hold all the SILC server
3695 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Made the configure.in.pre work on Solaris. Patch by salo.
3699 * Made all ciphers compatible with non-x86 machines. Defined
3700 CBC mode macros into lib/silccrypt/ciphers_def.h.
3702 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Fixed the make install.
3706 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * When MAC computation fails the silc_packet_decrypt returned 0
3709 even though it was supposed to return -1. Fixed this. The
3710 affected file is lib/silccore/silcpacket.c.
3712 * Do not replace the config files in /etc/silc (in make install)
3713 if they already exist. Affected file ./Makefile.am.
3715 * Do not send re-key packets immediately but through packet queue.
3716 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3718 * Changed silc_net_check_host_by_sock to return FALSE if the
3719 IP/DNS could not be resolved. Though, it returns the IP address
3720 now even if it could not resolve it (but returns also FALSE).
3721 Affected file lib/silcutil/silcnet.[ch].
3723 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3725 * Added silc_pkcs_decode_identifier to decode the public key's
3726 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3727 Added also silc_pkcs_free_identifier. Added also new context
3728 SilcPublicKeyIdentifier.
3730 * Added -S option to the silc client. It is used to dump the
3731 contents of the specified public key file.
3733 * Changed the PKCS api to return the public key length when
3734 setting the public key.
3736 * Fixed a fatal bug in the public and private key file loading.
3737 Affected file lib/silccrypt/silcpkcs.c.
3739 * Execute the packet parsing for client with zero (0) timeout
3740 if the protocol is active. Affected file silcd/server.c.
3742 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Made the key generation options to the silcd program. Added
3745 -C option, equivalent to client's option.
3747 * Added new [ServerKeys] config section to the server. It
3748 configures the server's public and private key.
3750 * Defined generic Public Key Payload into the protocol
3751 specification to send specific type of public keys and
3754 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3755 public key or certificate.
3757 * Implemented the GETKEY command to the server and to the
3758 client library and on user interface.
3760 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3762 * Made preliminary `make install' work.
3764 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added SilcServerRekey context into silcd/idlist.h.
3768 * Added the PFS support as defined in the specification to the
3769 SKE protocol. Affected files lib/silcske/*.c.
3771 * Added `ske_group' field to the SilcServerRekey context to hold
3772 the number of the SKE group that is used with PFS in re-key.
3773 Affected file silcd/idlist.h.
3775 * Added PFS re-key support to the server. Affected file is
3778 * Added silc_protocol_cancel to cancel execution of the next
3779 state of the protocol. Affected file is
3780 lib/silccore/silcprotocol.[ch].
3782 * Added the re-key support with and without PFS to the client
3783 library. Re-key is performed once in an hour, by default.
3785 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3786 Added silc_client_rekey_callback and silc_client_rekey_final.
3787 Affected files are lib/silcclient/protocol.[ch] and
3788 lib/silcclient/client.[ch].
3790 * Removed the `hmac_key' and `hmac_key_len' fields from the
3791 SilcClientConnection structure; not needed. Affected file is
3792 lib/silcclient/client.h.
3796 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Do not ask whether user wants to use the negotiated private key
3799 for private messages, just use it. Affected file is
3800 silc/local_command.c.
3802 * Added `send_enc_key' and `enc_key_len' fields to the
3803 SilcIDListData structure since they are needed in the re-key
3804 phase. Affected file is silcd/idlist.[ch].
3806 * Implemented the simple re-key protocol into the server.
3807 Affected files silcd/server.c and silcd/protocol.[ch]. The
3808 re-key will be performed once in an hour, by default.
3810 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3811 Added silc_server_rekey, silc_server_rekey_callback and
3812 silc_server_rekey_final.
3814 * Removed Tunneled flag from the protocol. Updated the code
3815 and the specifications.
3817 * Adde `pfs' field to the SilcIDListData to indicate whether
3818 the PFS is to be performed in the re-key. Affected file is
3821 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3824 int64 of at least the xintXX size. If void * is less that 4
3825 bytes uint32 * will be used. Defined bool as boolean.
3827 * Changed _ALL_ unsigned long and unsigned int to uint32,
3828 unsgined short to uint16 in the source tree.
3830 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3831 not handle clients that has entry->data.registered == FALSE.
3832 They are not in the network anymore. Affected file is
3835 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3837 * Implemented the sending of the SERVER_SIGNOFF notify in the
3838 server. Affected file is silcd/server.c.
3840 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3841 Added also silc_notify_payload_encode_args into the
3842 lib/silccore/silcnotify.[ch].
3844 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3845 Affected file silcd/packet_receive.c.
3847 * Implemented the SERVER_SIGNOFF notify handling in the client
3848 library. Affected file lib/silcclient/client_notify.c. Also,
3849 implemnted the printing of the SERVER_SIGNOFF info to the
3850 application. Affected file silc/client_ops.c.
3852 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3853 if the deleting was successful. Affected file silcd/idlist.[ch].
3855 * Added support for public key authentication in the connection
3856 authentication protocol in the client library. Affected file
3857 lib/silcclient/protocol.c.
3859 * Changed the server's silc_idlist_get_clients_by_* interface
3860 to support already allocated array so that new entries may be
3861 added to pre-allocated array. Affected file silcd/idlist.[ch].
3862 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3863 and command replies.
3865 * All command reply functions in the server now calls the
3866 pending command callback even if error occured. This way the
3867 error will be delivered to the client as well. Affected files
3868 silcd/command.c and silcd/command_reply.c.
3870 * Fixed INFO command to return local server's info if no server
3871 was provided. Affected file lib/silcclient/command.c.
3873 * Removed RESTART command for good. Updated the code and the
3876 * Rewrote parts of the task system. It is a bit simpler now.
3877 Removed unsued task priorities. The affected files are
3878 lib/silcutil/silctask.[ch].
3880 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Moved the USERS printing from the library to the application.
3883 Affected files lib/silcclient/command.c and silc/client_ops.c.
3885 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Added channel key re-key support. The re-key is perfomed
3890 only by the router and is done once in an hour. Added `rekey'
3891 field to the SilcChannelEntry in the server. Affected files
3892 silcd/server.c and silcd/idlist.h.
3894 * Added silc_task_unregister_by_context into the file
3895 lib/silcutil/silctask.[ch].
3897 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Added SILC_UMODE_GONE mode to indicate when the client is not
3900 present in the SILC network. Added also support to the local
3901 command AWAY that will set this mode. Added support of showing
3902 "xxx is gone" in WHOIS command. The USERS command shows the
3903 gone status as well.
3905 * Fixed setting server and router operator privileges in the
3906 server's UMODE command. Affected file silcd/command.c.
3908 * Merged the SKE KE1 and KE2 payloads into one payload. The
3909 new KE payload is equivalent to the old KE2 payload.
3911 Cleaned up the SKE Start Payload parsing. It now uses the
3912 simple buffer unformatting to do the parsing. A lot faster
3915 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3916 to the SKE that is used to indicate whether both of the SKE
3917 parties should perform authentication. By default only the
3918 responder performs authentication. By setting this flag also
3919 the initiator must do authentication. By default it is unset
3920 since in normal SKE case, client to server connection, only
3921 the responder should do authentication. When doing SKE between
3922 two clients both should perform authentication. Updated the
3923 code and the protocol specs.
3925 * A little fix to IDENTIFY command in the server. Search the
3926 client first by hash not nickname. Affected file is
3929 * Fixed the silc_client_close_connection to support closing
3930 the client to client connections wihtout deleting too much
3931 data. Affected file lib/silcclient/client.c.
3933 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3934 are received if protocol used to be active but is not anymore
3935 the application would crash due to NULL pointer dereference.
3936 Affected files silcd/server.c and lib/silcclient/client.c.
3938 * Added `hash' field to the SilcClientConnection to include
3939 the hash function negotiated in the SKE protocol.
3941 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3942 to set the channel founder authentication data. A client can
3943 claim the founder rights later by providing the authentication
3944 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3945 This way the channel founder can regain the channel founder
3946 privileges even it is left the channel. This works only on
3947 local server and the client must be connected to the same
3948 server to be able to regain the founder rights. Updated the
3949 protocol specs accordingly.
3951 Added support to the CMODE command in the client to set the
3952 founder auth data. Read the README to see how to set it.
3954 Added support to the CUMODE command to claim the founder
3955 rights. Read the README to see how to do it.
3957 Added support for the founder authentication to the Channel
3958 Entry in the server. Affected file silcd/idlist.h.
3960 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3961 server's CMODE command. Affected file silcd/command.c.
3963 * Added the following new functions into lib/silccore/silcauth.[ch]:
3964 silc_auth_get_method and silc_auth_get_data.
3966 * The server now saves the remote hosts public key to the
3967 SilcIDListData pointer. Affected file silcd/protocol.c.
3969 * The normal server now does not remove the channel entry from
3970 the cache if the founder authentication data is set. It used
3971 to remove it if the founder was the last one on the channel on
3972 the server and left the channel. The auth data is saved and
3973 if the channel is re-joined later the old entry is used with
3974 the old auth data. Affected files silcd/command_reply.c and
3977 * Removed the `pkcs' field from the SilcIDListData structure
3978 in the server; it is not used. Affected file silcd/idlist.h.
3980 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * Fixed packet processing on slow links. Partial packets were
3983 never re-processed because the incoming data buffer was cleared
3984 by the application. Application must not directly clear the
3985 sock->inbuf, the packet processing routines handle it. Fixed
3986 this in client library and in server.
3988 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Fixed the WHOIS and IDENTIFY send reply function to really
3991 check whether to send list or just one entry. Affected file
3994 * Cleaned up the LEAVE command's channel key distribution. The
3995 affected file silcd/command.c.
3997 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3998 can enforce the channel mode as well. In that case the ID
3999 includes the ID of the server. The code now enforces the
4000 mode change if the router have different mode than the server.
4002 * The notify client operation with CMODE_CHANGE notify can now
4003 return NULL client_entry pointer if the CMODE was not changed
4004 by client. Application must check for this.
4006 * Added <Server ID> argument to INFO command to support server
4007 info fetching by Server ID.
4009 * Added silc_server_announce_get_channel_users to get assembled
4010 packets of channel users of the specified channel. Affected
4011 file silcd/server.[ch].
4013 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4014 was freed underneath the ID Cache.
4016 * Re-announce clients when the server received CHANNEL_CHANGE
4017 notify from the router. Affected file silcd/packet_send.c.
4019 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4022 crashed since it did not handle the fact that there is no cipher
4023 called "3" and didn't check the error condition. Now fixed.
4025 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4026 flag. It can be used to send message requests.
4028 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Implemented the RESTART command in the client.
4032 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4033 notice type messages. Added notice printing to the user
4036 * The channel keys are not re-generated if the channel's mode
4037 is PRIVKEY, ie private key on the channel exists. Affected
4038 files silcd/server.c and silcd/command.c.
4040 * Fixed a little bug in channel message delivery when channel
4041 private keys are set in the server. Affected file is
4042 silcd/packet_send.c.
4044 * Changed the setting on channel->on_channel = TRUE from the
4045 silc_client_save_channel_key to the JOIN command reply. The
4046 key payload is not received if the private channel key is set.
4047 Affected file lib/silcclient/command_reply.c and the
4048 lib/silcclient/client_channel.c.
4050 * When the CMODE_CHANGE notify is sent and the channel private
4051 key mode is removed the channel key must be re-generated in
4052 other cells as well. Added this support for the router in the
4053 silcd/packet_receive.c.
4055 * Added new local command NOTICE to send notice message on
4056 channel. Affected file silc/local_command.[ch].
4058 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Added new local command ME to the client. It is used to send
4061 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4062 some action. Affected file silc/local_command.[ch].
4064 * Changed channel_message and private_message client operations
4065 to deliver the message flags to the application. Added also
4066 the `flags' arguments to the silc_client_send_channel_message
4067 and silc_client_send_private_message functions. Affected file
4070 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4072 * Redefined the Private Message Payload to support private message
4073 keys and to support the new private message flags. Updated
4074 the protocol specs. Flags makes it possible to have for example
4075 CTCP style messages.
4077 * Added new type SilcPrivateMessagePayload and defined an API
4078 for it in the lib/silcclient/silcprivate.[ch].
4080 * Tested private message private keys successfully. Tested the
4081 private message key set, unset and list commands with the new
4084 * Redefined the Channel Message Payload to include the channel
4085 message flags (equal with private message flags) to support
4086 for example CTCP style messages.
4088 * Defined some of the message (for channel and private message)
4089 flags. Updated the protocol specs and added the flags to the
4090 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4092 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Added SilcKeyAgreementStatus type to the key agreement routines
4095 to indicate the current status and error if one occured.
4096 The status types are defined in the lib/silcclient/silcapi.h.
4098 * Added new local command KEY that is used to set and unset private
4099 keys for channels, set and unset private keys for private messages
4100 with remote clients and to send key agreement requests and
4101 negotiate the key agreement protocol with remote client. The
4102 key agreement is supported only to negotiate private message keys,
4103 it currently cannot be used to negotiate private keys for channels,
4104 as it is not convenient for that purpose.
4106 * Fixed a minor pending callback setting bug in the function
4107 silc_client_get_client_by_id_resolve, now the function works.
4108 Affected file lib/silcclient/idlist.c.
4110 * Added function silc_net_get_local_port to get local bound
4111 port by socket. Added to lib/silcutil/silcnet.[ch].
4113 * Added `sockets' and `sockets_count' fields to the SilcClient
4114 object. They hold the sockets of the listenning sockets in
4115 the client. Listenning sockets may be for example the key
4116 agreement server. Affected file lib/silcclient/client.[ch].
4117 Added functions the silc_client_add_socket and the
4118 silc_client_del_socket. They are exported to the application
4121 * Added ~./silc/clientkeys to support other client's public keys.
4123 * Renamed verify_server_key client operation to verify_public_key
4124 and added one argument to indicate the type of the connection
4125 (server, client etc.).
4127 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Added silc_server_connection_auth_request to handle the
4130 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4131 silcd/packet_receive.[ch].
4133 * Added silc_server_send_connection_auth_request into the
4134 silcd/packet_send.c to send the connection auth request packet.
4136 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4139 * Fixed the public key authentication in responder side in the
4140 server. The `auth_data' pointer includes the SilcPublicKey
4141 not the path to the public key. Affected file silcd/protocol.c.
4143 * Implemented the public key authentication in the initiator side
4144 in the server. Affected file silcd/protocol.c.
4146 * Removed the [RedirectClient] config section from the server
4147 configuration. Is not needed and I don't want to implement it.
4149 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Cleaned up the CMODE command in the server. It now works
4152 correctly and supports all the modes defined in the protocol.
4153 Affected file is silcd/command.c.
4155 * Added `hmac_name' field to the SilcChannelEntry in the server
4156 to hold the default HMAC of the channel. It can be set when
4157 creating the channel (with JOIN command). Affected files
4160 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4161 type to indicate the change of the current cipher and hmac
4162 on the channel. Client can safely ignore the <cipher> argument
4163 (if it chooses to do so) since the CHANNEL_KEY packet will
4164 force the channel key change anyway. The <hmac> argument is
4165 important since the client is responsible of setting the new
4166 HMAC and the hmac key into use.
4168 * Fixed the CMODE command in the client library as well.
4170 * Tested CMODE command in router environment successfully.
4172 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Show the version of the remote client (or server) when connecting
4175 to the server. It is logged to the log file. Affected file
4176 is silcd/protocol.c.
4178 * Fixed the KILLED notify handling in the client library. The
4179 client must be removed from all channels when receiving the
4182 Also, do not remove the client entry when giving the KILL
4183 command but when the KILLED notify is received.
4185 * Removed silc_idlist_find_client_by_nickname from the server.
4186 Not needed anymore. Affected files silcd/idlist.[ch].
4188 * Implemented the CHANNEL_CHANGE notify type handling to the
4189 server. Affected file silcd/server.c.
4193 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4195 * Added silc_server_send_notify_invite to send the INVITE
4196 notify between routers.
4198 * Implemented the INVITE command correctly to the server.
4200 * Implemented the INVITE notify type handling in the server.
4202 * Implemented the INVITE command to the client library and on the
4205 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Added function silc_server_get_client_resolve to find the
4208 client entry by ID from all ID lists and then resolve it
4209 (using WHOIS) if it cannot be found. Affected file is
4212 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4214 * Implemented the BAN command to the client library.
4216 * The JOIN command in the server now checks the invite list
4219 * Changed the silc_command_reply_payload_encode_va and the
4220 silc_command_payload_encode_va to support that if argument is
4221 NULL it ignores and checks the next argument. Affected file
4222 lib/silccore/silccommand.c.
4224 * Added silc_server_send_notify_ban to send the BAN notify
4225 type between routers.
4227 * Chaned the silc_notify_payload_encode to support that if
4228 argument is NULL it ignores and checks the next argument.
4229 Affected file lib/silccore/silcnotify.c.
4231 * Tested ban lists in router environment successfully.
4233 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Implemented BAN command to the server, in silcd/command.[ch].
4237 * Removed the BAN and INVITE_LIST modes from the CMODE command
4240 * Added function silc_string_match to regex match two strings.
4241 Affected files lib/silcutil/silcutil.[ch].
4243 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Redefined parts of the SilcChannelEntry in the server to support
4246 the new ban and invite lists.
4248 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Redefined the INVITE command. The same command can be used to
4251 invite individuals to the channel but also to manage the invite
4252 list of the channel (to add to and remove from the invite list).
4253 Updated the protocol specs.
4255 * Added new command SILC_COMMAND_BAN that can be used to manage
4256 the ban list of the channel. Updated the protocol specs.
4258 * Removed the channel modes: the SILC_CMODE_BAN and the
4259 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4260 in the CMODE command. The equivalent features are now available
4261 using INVITE and BAN commands. Updated the protocol specs.
4263 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4264 in the network about change in the current ban list. The notify
4265 type is not used by the client.
4267 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4268 support the invite lists.
4270 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added new function silc_string_regexify that converts string
4273 including wildcard characters into regex string that can
4274 be used by the GNU regex library. Added into the file
4275 lib/silcutil/silcutil.[ch].
4277 Added silc_string_regex_combine to combine to regex strings
4278 into one so that they can be used as one regex string by
4279 the GNU regex library. Added into the file
4280 lib/silcutil/silcutil.[ch].
4282 Added silc_string_regex_match to match two strings. It returns
4283 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4285 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Imported GNU regex to the soruce tree into lib/contrib.
4288 Fixed some compiler warning from the regex.c.
4290 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Fixed MOTD command in the server to work in router environment.
4294 * Fixed the MOTD command in the client library to support
4295 the server argument in the command.
4297 * Added `nickname_len' argument to the silc_idlist_add_client
4298 in the server, as the `nickname' argument may be binary data
4301 * Added silc_idlist_get_channels to return all channels from
4304 * Implemented LIST command to the server. Affected file is
4307 * Implemented the LIST command to the client library and on the
4310 * Added [<user count>] argument to the LIST command reply.
4311 With private channels the user count is not shown.
4313 * Updated TODO and README.
4315 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * The client entry's data.registered must be TRUE even with
4318 global client entry on global client list. The data.registered
4319 is used to check whether the client is anymore in the network,
4320 for example with WHOWAS command so it must be valid.
4322 * Fixed the WHOWAS command in the server. It now actually works
4323 in router environment. Added function into silcd/command_reply.c
4324 silc_server_command_reply_whowas_save.
4326 * Added silc_idlist_purge function to the silcd/idlist.c
4327 to periodically purge the ID Cache.
4329 * Fixed INFO command in the server. It works now in router
4330 environment. Added <server name> argument to the INFO command
4331 reply. Updated the protocol specs.
4333 * Fixed minor bug in silc_idcache_purge to not purge if the
4334 expire value is zero.
4336 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4337 they were buggy because of the WHOWAS information.
4339 * Fixed local command MSG to handle the async resolving of
4340 the remote client properly. It used to fail the first MSG.
4341 Affected file silc/local_command.c.
4343 * Added `data_len' field to SilcIDCache context.
4345 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Update TODO. Todo in commands in the server.
4349 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4352 used by routers as broadcast packet to inform other routers
4353 about the changed user mode.
4355 Implemented the notify handling in the server. Affected file is
4356 silcd/packet_receive.c. Added the function
4357 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4359 * Added new generic Channel Payload and deprecated the New Channel
4360 Payload. The New Channel Payload is now the generic Channel
4363 * Added new argument `mode' to the silc_server_send_new_channel
4364 as it is required in the Channel Payload now.
4366 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4367 and created a new and real SilChannelPayload to represent the
4368 new generic Channel Payload. Implemented the encode/decode
4369 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4371 * Added silc_server_get_client_channel_list to return the list
4372 of channels the client has joined for WHOIS command reply.
4373 Affected file silcd/server.[ch].
4375 * Implemented the channel list sending in the WHOIS command reply
4376 in server and in the client.
4378 Implemented the channel list displaying on the user interface
4379 as well. Affected file silc/client_ops.c.
4381 * Added silc_channel_payload_parse_list to parse list of Channel
4382 Payloads. It returns SilcDList list of SilcChannelPayloads.
4383 Client for example can use this function to parse the list of
4384 channels it receives in the WHOIS command reply. The caller
4385 must free the list by calling silc_channel_payload_list_free.
4386 Affected files lib/silccore/silcchannel.[ch].
4388 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added one new argument <user mode> to the WHOIS command reply
4391 to return the mode of the user in SILC. Updated the protocol
4394 Implemented it to the server and client.
4396 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Fixed the mode printing on the user interface on joining.
4399 Affected file silc/client_ops.c.
4401 * Implemented the UMODE command and user modes in general to the
4402 client library and to the user interface.
4404 * Implemented the UMODE command to the server.
4406 * The server now sends UNKNOWN_COMMAND error status if client sends
4407 unknown command. Affected file silcd/command.c.
4409 * All server commands now handle the command identifier the right
4410 way when sending the command reply to the client. The client can
4411 use to identify the command replies with the identifier.
4413 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Added silc_server_get_client_route to resolve the route to
4416 the client indicated by the client ID. Affected file is
4419 * Added silc_server_relay_packet as general function to relay
4420 packet to arbitrary destination. This deprecates functions
4421 like _send_private_message_key, _relay_notify etc. Affected
4422 file is silcd/packet_send.[ch].
4424 Removed silc_server_send_key_agreement,
4425 silc_server_send_private_message_key and
4426 silc_server_packet_relay_notify functions from the file
4427 silcd/packet_send.[ch].
4431 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4432 server. Affected file silcd/packet_receive.[ch].
4434 * Implemented the KILL command to the client. Implemented the
4435 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4436 Affected files lib/silcclient/command[_reply].c and
4437 lib/silcclient/client_notify.c. Implemented the KILL notify
4438 printing in the user inteface.
4440 * Fixed a lot silc_parse_nick memory leaks from the client
4441 library in the file lib/silcclient/command.c.
4443 * Changed the silc_server_send_notify_on_channels's `sender'
4444 argument from SilcSocketConnection to SilcClientEntry to
4445 check the sender as entry and not as connection object and not
4446 to send to the client provided as argument. The affected file
4447 is silcd/packet_send.[ch].
4449 * The notify packets that are destined directly to the client used
4450 to not to be processed by the server. Now changed that and the
4451 server processes all notify packets. After relaying the packet
4452 to the client the notify packet is processed in the server.
4454 * The silc_server_free_client_data now checks whether there is
4455 pending outgoing traffic for the client and purges the data to
4456 the network before removing the client entry.
4458 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4461 an client is killed from the SILC Network. Updated the protocol
4464 Added new function silc_server_send_notify_killed to the
4465 silcd/packet_send.[ch].
4467 * Added function silc_server_packet_relay_notify to relay notify
4468 packets that are destined directly to a client. In this case
4469 the server does not process the notify packets but merely relays
4470 it to the client. Affected file silcd/packet_send.[ch].
4472 Added also silc_server_packet_process_relay_notify to check
4473 whereto relay the notify. Affected file is
4474 silcd/packet_receive.[ch].
4476 * Implemented the KILL command to the server.
4480 * Added the backup schema desgined last fall to the protocol
4481 specs for everyone to see. The specification is in the
4482 *-spec-xx.txt draft and the packet type definitions for the
4483 backup routers is in *-pp-xx.txt draft. Thusly, added also
4484 new packet type SILC_PACKET_CELL_ROUTERS.
4486 * A big security problem in the implementation discovered. The
4487 signoff of an client did not cause new channel key generation
4488 which it of course should've done. The channel keys must be
4489 always re-generated when client leaves (or signoffs) the channel.
4490 The silc_server_remove_from_channels funtion now handles
4491 the channel key re-generation.
4493 * Added `sender' argument to the silc_server_send_notify_on_channels
4494 to not to send the client provided as argument. Affected file
4495 silcd/packet_send.[ch].
4497 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Implemented OPER and SILCOPER commands into the server and
4502 * Added silc_auth_verify and silc_auth_verify_data to verify
4503 the authentication directly from the authentication payload.
4504 It supports verifying both passphrase and public key based
4505 authentication. Affected file lib/silccore/silcauth.[ch].
4507 * Added `hash' field to the SilcIDListData structure. It is the
4508 hash negotiated in the SKE protocol. Affected file is
4511 * Slight redesigning of the SilcAuthPayload handling routines.
4512 Do not send SilcPKCS but SilcPublicKey as argument.
4514 * Implemented the public key authentication support to the
4515 serverconfig. The public key is loaded from the provided path
4516 and saved as authentication data to void * pointer. Thus,
4517 changed the unsigned char *auth_data to void *auth_data;
4519 * Fixed SHUTDOWN command to send the reply before the server
4520 is shutdown. :) Affected file silcd/command.c.
4522 * Fixed fatal bug in CONNECT command. The hostname was invalid
4523 memory and server crashed. Affected file silcd/command.c.
4525 * Fixed fatal bug in CLOSE command. The server_entry became
4526 invalid but was referenced later in the command. Affected file
4529 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Fixed fatal bug in failure packet handling. Server ignored
4532 the failure and thus crashed when it came.
4536 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4539 that the command may be executed only once in (about) 2 seconds.
4540 The old SILC_CF_LAG flag is same but allows command bursts up
4541 to five before limiting.
4543 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4544 server code. Various commands now includes the CF_LAG_STRICT
4545 flag to disallow any kind of miss-use of the command.
4547 * Fixed the silc_buffer_unformat to not to allocate any data
4548 if the length of the data is zero. It used to allocate the
4549 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4551 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Changed the format of AdminConnection configuration section
4554 in the server. Added username of the admin to the format.
4555 Affected files silcd/serverconfig.[ch].
4557 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4558 to return admin configuration data by host, username and/or
4561 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Implemented WHOWAS command to the server. Added the functions:
4565 silc_server_command_whowas_parse,
4566 silc_server_command_whowas_send_reply,
4567 silc_server_command_whowas_from_client and
4568 silc_server_command_whowas_from_server
4570 * Added <Client ID> argument to the WHOWAS command reply. Updated
4571 the protocol specs accordingly.
4573 * Implemented WHOWAS command and command_reply to the client
4576 Implemented the WHOWAS printing on the user interface.
4578 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Added new argument to the WHOWAS command reply, the real name.
4581 It is an optional argument. Updated the protocol specs.
4583 * Added SilcIDCacheDestructor callback that is registered when
4584 the SilcIDCache is allocated. The callback is called when
4585 an cache entry in the ID Cache expires, or is purged from the
4586 cache. Added into lib/silccore/idcache.[ch].
4588 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4589 to destruct the client entries when the cache entry expires.
4590 Other ID Cache's in server and in the client library ignores
4593 * If the ID Cache entry's `expire' field is zero then the entry
4594 never expires. Added boolean `expire' argument to the
4595 silc_idcache_add function in the lib/silccore/idcache.[ch].
4596 If it is TRUE the default expiry value is used.
4598 * Added silc_server_free_client_data_timeout that is registered
4599 when client disconnects. By default for 5 minutes we preserve
4600 the client entry for history - for WHOWAS command.
4602 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added support to the server to enforce that commands are not
4605 executed more than once in 2 seconds. If server receives
4606 commands from client more frequently, timeout is registered
4607 to process the commands. Affected file silcd/command.c.
4608 Added new function silc_server_command_process_timeout.
4610 * Changed NICK_NOTIFY handling in client library to check that
4611 if the client's nickname was changed, so there is no need to
4612 resolve anything from the server.
4614 * Removed error printing from the WHOIS and IDENTIFY commands.
4615 If error occurs then it is ignored silently in the client library.
4616 The application, however, may map the received error to
4617 human readable error string. The application currently maps
4618 the NO_SUCH_NICKNAME error to string.
4620 * Made the command status message public to the application. Moved
4621 them from lib/silcclient/command_reply.c to
4622 lib/silcclient/command_reply.h. The application can map the
4623 received command status to the string with the
4624 silc_client_command_status_message function.
4626 * Added check to the server to check that client's ID is same
4627 as the Source ID in the packet the client sent. They must
4630 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Added dist-bzip hook to the Makefile.am to make bzip2
4633 compressed distributions.
4635 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * Server now enforces the maximum length for the nickname and
4638 the channel as protocol specification dictates. 128 bytes for
4639 nickname and 256 bytes for channel name.
4641 * Moved the WHOIS printing to the application. The client libary
4642 does not print out the WHOIS information anymore, the application
4643 must do it. Renamed silc_client_command_reply_whois_print to
4644 the silc_client_command_reply_whois_save.
4646 The client's idle time is also sent to the application now, and
4647 the idle is shown on screen.
4649 * Added silc_client_command_reply_identify_save to save the
4650 received IDENTIFY entries.
4652 * Do not check for channel private keys in message sending and
4653 reception if the channel does not have the PRIVKEY mode set.
4654 Affected file lib/silclient/client_channel.c.
4656 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4659 just surfaced after chaning the JOIN procedure.
4661 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Added silc_client_get_clients_by_list to get client entries
4664 from Client ID list, that is returned for example by JOIN
4665 and USERS command replies. The application should use this
4666 function for example when JOIN command reply is received to
4667 resolve the clients already on the channel (library does not
4668 do that anymore as USERS command reply is not used in the JOIN
4669 procedure anymore). Affected files lib/silcclient/silcapi.h and
4670 lib/silcclient/idlist.c.
4672 * JOIN command reply and USERS command reply returns now SilcBuffer
4673 pointers instead of unsigned char pointers when returning
4674 the client list and mode list.
4676 * Added <Client ID> argument to the JOIN command reply, mainly
4677 for the server to identify for which client the command was
4678 originally sent. Updated protocol specs accordingly.
4680 * Added SilcDlist private_key pointer to the SilcChannelEntry
4681 in the client to support the channel private keys. Affected
4682 file is lib/silcclient/idlist.h.
4684 * Added SilcChannelPrivateKey argument to the function
4685 silc_client_send_channel_message so that application can choose
4686 to use specific private ke if it wants to. If it is not provided,
4687 the normal channel key is used, unless private keys are set.
4688 In this case the first (key that was added first) is used
4689 as the encryption key.
4691 * Implemented the support for channel private key handling.
4692 Implemented the following functions:
4694 silc_client_add_channel_private_key,
4695 silc_client_del_channel_private_keys,
4696 silc_client_del_channel_private_key,
4697 silc_client_list_channel_private_keys and
4698 silc_client_free_channel_private_keys
4700 Affected file lib/silcclient/client_channel.c.
4702 * Added the support for the private keys in the channel message
4703 sending and encryption and in the message reception and
4704 decryption. Affected funtions are
4705 silc_client_send_channel_message and silc_client_channel_message.
4707 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added SKE's key verify callback to the client library's
4710 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4712 * Removed the statement that server (or router) must send USERS
4713 command reply when joining to the channel so that the client
4714 knows who are on the channel. Instead, the client list and
4715 client's mode list is now sent in the JOIN command reply to the
4716 client who joined channel. This is better solution.
4718 * Added function silc_server_get_users_on_channel and function
4719 silc_server_save_users_on_channel to the silcd/server.[ch].
4721 * Removed function silc_server_command_send_users from the
4724 * Do not show topic on the client library anymore. The topic is
4725 sent in the command reply notify to the application and the
4726 application must show the topic now.
4728 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Added client searching by nickname hash into the IDENTIFY and
4731 WHOIS commands in the server as they were clearly missing from
4732 them. Affected file is silcd/command.c.
4734 * Fixed a bug in private message receiving in the client library.
4735 The remote ID was freed and it wasn't supposed, now it is
4738 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Minor fix to the channel payload; allocate the data area, as it
4741 needs to be of specific length.
4743 * If the key agreement port is zero then the operating
4744 system will define the bound port. Affected files are
4745 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4747 * Added new function silc_channel_payload_decrypt into the file
4748 lib/silccore/silcchannel.[ch].
4750 * Moved the channel message etc, check from silc_packet_decrypt
4751 to applications. The library calls now a generic
4752 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4753 when the packet is either normal or special. This was done to
4754 allow more wide range of checking that was not allowed when
4755 the code was in library. Now applications can do virtually any
4756 checks to the packet and return to the library the decision how
4757 the packet should be processed. Affected files are
4758 lib/silccore/silcpacket.[ch].
4760 Added silc_server_packet_decrypt_check to the server and
4761 silc_client_packet_decrypt_check to the client library.
4763 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4764 to send with specified source and destination information.
4766 * Channel message delivery between routers was broken after the
4767 channel key distribution was fixed earlier. The channel key
4768 was used be to distributed to other routers as well which is not
4769 allowed by the protocol. Now this is fixed and channel keys
4770 really are cell specific and the channel message delivery between
4771 routers comply with the protocol specification.
4773 * Fixed various commands in server to check also the global list
4774 for the channel entry and not just the local list. The affected
4775 file silcd/command.c.
4777 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added assert()s to buffer formatting and unformatting routines
4780 to assert (if --enable-debug) when error occurs. Affected
4781 file: lib/silcutil/silcbuffmt.c.
4783 * Changed to auto-reconnect to check whether the remote host is
4784 router and register the re-connect timeout if it is. It used
4785 to check that whether we are normal server, but router must do
4786 auto-reconnect with another router as well. Affected file
4789 * Removed the [<key len>] option from CMODE command as the cipher
4790 name decides the key length, nowadays. See the defined ciphers
4791 from the protocol specification.
4793 * Added [<hmac>] option to the CMODE command to define the HMAC
4794 for the channel. Added SILC_CMODE_HMAC channel mode.
4796 * Added [<hmac>] option for the JOIN command so that user can
4797 select which HMAC is used to compute the MACs of the channel
4800 * Added Hmac field to the Channel Message Payload. The integrity
4801 of plaintext channel messages are now protected by computing
4802 MAC of the message and attaching the MAC to the payload. The
4803 MAC is encrypted. Now, it is clear that this causes some
4804 overhead to the size of the packet but rationale for this is that
4805 now the receiver can verify whether the channel message decrypted
4806 correctly and also when private keys are set for the channel the
4807 receiver can decrypt the packet with several keys and check from
4808 the MAC which key decrypted the message correctly.
4810 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4811 lib/silccrypt/silccipher.[ch].
4813 * Added silc_hash_len to return the digest length into the
4814 lib/silcrypt/silchash.[ch].
4816 * Rewrote parts of Silc Channel Payload interface in the
4817 lib/silccore/silcchannel.[ch]. The encode function now also
4818 encrypts the packet and parse function decrypts it.
4820 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Fixed a minor formatting bug in the SKE's key material processing.
4823 It actually might have processed the keys wrong way resulting
4826 * Redefined the mandatory HMAC algorithms and added new algorithms.
4827 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4828 and hmac-md5 truncated to 96 bits. The mandatory is now
4829 hmac-sha1-96. Rest are optional (including the one that used
4830 to be mandatory). Rationale for this is that the truncated HMAC
4831 length is sufficient from security point of view and can actually
4832 make the attack against the HMAC harder. Also, the truncated
4833 HMAC causes less overhead to the packets. See the RFC2104 for
4836 * Added new [hmac] configuration section. The SKE used to use
4837 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4838 is of course wrong. The official names that must be proposed in
4839 the SKE are the ones defined in the protocol specification
4840 (hmac-sha1-96 for example). The user can configure any hmac
4841 using any hash function configured in the [hash] section. At
4842 least, the mandatory must be configured.
4844 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4846 * Added HMAC list to the SKE proposal list. It has now both
4847 hash algorithm list and HMAC list. This makes the protocol
4848 incompatible with previous versions. The SKE now seems to work
4849 the way it is supposed to work, for the first time actually.
4851 * Defined plain Hash algorithms to the protocol specification.
4854 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Implemented support for key agreement packets into the server.
4857 Added functions silc_server_key_agreement and
4858 silc_server_send_key_agreement. Other than these functions,
4859 server has nothing to do with this packet.
4861 * Added support for private message key packets into the server.
4862 Added functions silc_server_private_message_key and
4863 silc_server_send_private_message_key.
4867 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4868 called in the protocol's final callback instead in the END
4869 protocol state. This makes a little more sense and in the same
4870 time in client we can use the same protocol routines for normal
4871 key exchange and to key agreement packet handling as well.
4873 * Added to both client's and server's KE protocol context the
4874 SilcSKEKeyMaterial pointer to save the key material. We will
4875 bring the key material to the protocol's final callback by doing
4876 this. The final callback must free the key material.
4878 * Added SKE's packet_send callback into client's KE protocol
4879 context so that the caller can choose what packet sending function
4880 is used. This way we can use different packet sending when
4881 doing normal SKE when doing key agreement packet handling (in
4882 the key agreement packet handling we do not want to encrypt
4885 * Implemented the responder side of the key agreement routines
4886 in the client. The client can now bind to specified port and
4887 accept incoming key negotiation. The key material is passed
4888 to the application after the protocol is over.
4890 * Implemented the processing of incoming Key Agreement packet
4891 in the client. Added function silc_client_key_agreement to
4894 * Implemented the intiator side of the key agreement routines
4895 in the client. The client can now initiate key agreement with
4896 another remote client. The key material is passed to the
4897 application after the protocol is over.
4899 * Created client_keyagr.c to include all the key agreement
4902 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4903 SILC_TASK_CALLBACK except that it is not static.
4905 * Created client_notify.c and moved the Notify packet handling
4906 from the client.[ch] into that file.
4908 * Created client_prvmsg.c and moved all private message and
4909 private message key routines from the client.[ch] into that file.
4911 * Create client_channel.c and moved all channel message and
4912 channel private key routines from the client.[ch] into that file.
4914 * Changed silc_client_get_client_by_id_resolve to resolve with
4915 WHOIS command instead of IDENTIFY command, in the file
4916 lib/silclient/idlist.c.
4918 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Implemented the SKE's responder side to the Client library.
4922 * When FAILURE is received to the protocol do not trust it
4923 blindly. Register a timeout to wait whether the remote closes
4924 the connection as it should do it, only after that process the
4925 actual failure. This was changed to both client and server.
4927 * Added client_internal.h to include some of the structures
4928 there instead of client.h in lib/silcclient/.
4930 * Added function silc_task_unregister_by_callback to unregister
4931 timeouts by the callback function.
4933 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Some "Incomplete WHOIS info" errors has been appearing on the
4936 log files. Took away the entry->userinfo check from WHOIS
4937 reply sending. The entry->userinfo is now " " if client did not
4938 provide one. I thought this was fixed earlier but something
4939 is wrong still. Let's see if the error still appears.
4941 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Fixed a minor bug in the login when the channel key is
4944 re-generated in the server. It used to generate the key in
4945 wrong order and thus caused problems in the channel traffic.
4947 * Fixed a minor bug in channel key distsribution after
4948 KICK command. The key was not sent to the router even though
4951 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Added silc_ske_process_key_material_data as generic routine
4954 to process any key material as the SILC protocol dictates. The
4955 function is used by the actual SKE library but can be used by
4956 applications as well. This relates to the private message keys
4957 and the channel private keys since they must be processed the
4958 same way the normal SILC session keys. The protocol dictates
4959 this. Affected files: lib/silcske/silcske.[ch].
4961 Added also silc_ske_free_key_material to free the
4962 SilcSKEKeyMaterial structure.
4964 * Defined silc_cipher_set_key function to set the key for
4965 cipher without using the object's method function. The affected
4966 files: lib/silccrypt/silccipher.[ch].
4968 * Implemented silc silc_client_add_private_message_key,
4969 silc_client_add_private_message_key_ske,
4970 silc_client_del_private_message_key,
4971 silc_client_list_private_message_keys and
4972 silc_client_free_private_message_keys functions in the
4975 Added functions silc_client_send_private_message_key to send
4976 the Private Message Key payload and silc_client_private_message_key
4977 to handle incoming Private Message Key payload.
4979 * Added Cipher field to the Private Message Key payload to set
4980 the cipher to be used. If ignored, the default cipher defined
4981 in the SILC protocol (aes-256-cbc) is used.
4983 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Removed lib/silcclient/ops.h file.
4987 Redefined parts of the SILC Client Library API. Created new
4988 file silcapi.h that deprecates the ops.h file and defines the
4989 published Client Library API. Defined also private message key
4990 API and channel private key API into the file.
4992 This is the file that the application must include from the
4993 SILC Client Library. Other files need not be included by
4994 the application anymore.
4996 * Added new key_agreement client operation callback and also
4997 defined the Key Agreement library API for the application.
4999 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5002 is used by clients to request key negotiation between another
5003 client in the SILC network. If the negotiation is started it
5004 is performed using the SKE protocol. The result of the
5005 negotiation, the secret key material, can be used for example
5006 as private message key.
5008 Implemented the Key Agreement payload into the files
5009 lib/silccore/silauth.[ch].
5011 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5013 * Redefined ciphers for the SILC protocol. Added some new ciphers
5014 and defined the key lengths for the algorithms. Changed the
5015 code accordingly. The default key length is now 256 bits.
5017 * Fixed SKE key distribution function silc_ske_process_key_material
5018 when the key length is more than 128 bits. The default key
5019 length in SILC is now 256 bits.
5021 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5022 to indicate unsupported algorithm.
5024 * Renamed rijndael.c to aes.c and all functions as well.
5026 * Fixed a long standing channel key setting bug in client library.
5027 Weird that it has never surfaced before.
5029 * Fixed bug in channel deletion. If the entire channel is removed
5030 then it must also delete the references of the channel entry
5031 from the client's channel list as the client's channel entry and
5032 the channel's client entry share same memory.
5034 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Implemented CONNECT and SHUTDOWN commands in the client.
5038 * Implemented CLOSE command to the client.
5040 * Added the function silc_idlist_find_server_by_name into the
5041 files silcd/idlist.[ch].
5043 Added the function silc_idlist_find_server_by_conn into the
5044 files silcd/idlist.[ch].
5046 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * DIE command was renamed to SHUTDOWN. Updated the both code
5051 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5052 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5054 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5057 * Added function silc_server_create_connection function to create
5058 connection to remote router. My server implementation actually
5059 does not allow router to connect to normal server (it expects
5060 that normal server always initiates the connection to the router)
5061 so the CONNECT command is only good for connecting to another
5064 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5067 or some other client was kicked from the channel.
5069 Implemented the handling of the notify type to both client
5072 Implemented silc_server_send_notify_kicked to send the KICKED
5073 notify. It is used to send it to the server's primary router.
5075 * Implemented the KICK command into server and client.
5077 * Added `query' argument to the silc_idlist_get_client function
5078 to indicate whether to query the client from server or not if
5081 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5082 to indicate that the client is not channel founder.
5086 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Removed the rng context from SilcPacketContext structure and
5089 changed that the packet routine uses the Global RNG API.
5091 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added support for quit message that client can "leave" on the
5094 channel when it quits the SILC. It is ditributed inside the
5095 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5097 Added silc_server_free_client_data that will take the
5098 signoff message as argument.
5100 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5102 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Updated parts of the protocol specification to keep it up
5107 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5110 payloads in one packet.
5112 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5113 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5114 use now the new List flag.
5116 * Also deprecated the following packet types: REPLACE_ID,
5117 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5119 * Added list support for Notify packet in server.
5121 * Added silc_server_send_notify_channel_change to send the
5122 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5123 the silc_server_send_replace_id.
5125 * Added silc_server_send_notify_nick_change to send the
5126 NICK_CHANGE notify type. Deprecates the function
5127 silc_server_send_replace_id.
5129 * Added silc_server_send_notify_join to send the JOIN notify type.
5130 Deprecates the function silc_server_send_new_channel_user.
5132 * Added silc_server_send_notify_leave to send LEAVE notify type.
5133 Deprecates the function silc_server_send_remove_channel_user.
5135 * Added silc_server_send_notify_cmode and
5136 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5137 types. Deprecates the silc_server_send_set_mode function.
5139 * Added SERVER_SIGNOFF notify type to indicate that server has
5140 quit. This means that all clients on the channel from that
5141 server will drop. This can be also used when netsplit happens.
5143 Deprecated REMOVE_ID packet type since it is not needed anymore
5146 Added silc_server_send_notify_server_signoff to send the
5147 SERVER_SIGNOFF notify type. Deprecates the function
5148 silc_server_send_remove_id.
5150 Added also silc_server_send_notify_signoff to send the
5151 SIGNOFF notify type.
5153 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5154 SILC protocol from this day on. Changed the protocol
5155 specification as well.
5157 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5158 notify type. It is used between routers to notify about
5159 topic changes on a channel.
5161 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5164 * Partly updated the protocol specification to comply with the
5165 changes now made. It is still though a bit outdated.
5167 * The JOIN notify type now takes one extra argument <Channel ID>.
5168 The packet used to be destined to the channel but now the
5169 JOIN type may be sent as list thus it is impossible to
5170 destine it to any specific channel. By adding this argument
5171 it is again possible.
5173 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Added CREDITS file. The CHANGES and CREDITS file will appear
5176 in the distribution as well.
5178 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5181 types in the server's silcd/packet_receive.c.
5183 * Implemented CMODE and CUMODE to work in router environment.
5185 * Fixed minor encoding and decoding buglet from the
5186 lib/silccore/silcmode.c.
5188 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5191 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5193 * Changed all SilcConfigServer* and silc_config_server* to
5194 SilcServerConfig* and silc_server_config*, respectively.
5197 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Associated the ID (client or server ID) to the Authentication
5200 Payload to avoid any possibility of forging. Updated the
5201 protocol specification and the code accordingly.
5203 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * The RSA key length is now save to the RsaKey context in the
5206 key generation process in lib/silccrypt/rsa.c. The key length
5207 is now used to figure out the maximum size of the block allowed
5208 to be encrypted/signed.
5210 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5211 is equivalent to the silc_mp_mp2bin but does not allocate any
5214 * Changed silc_mp_mp2bin API to take length argument. If it is
5215 non-zero then the buffer is allocated that large. If zero, then
5216 the size is approximated using silc_mp_sizeinbase, which however
5219 * Created Global RNG API which is global RNG that application can
5220 initialize. After initializing, any routine anywhere in the
5221 code (including library) can use RNG without allocating a new
5222 RNG object. This was done to allow this sort of use of the
5223 RNG in code that has no chance to allocate RNG object. All
5224 applications currently allocate this and many routines in the
5225 library use this. Affected file lib/silccrypt/silcrng.[ch].
5227 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5228 it to use the Global RNG API.
5230 * Defined Authentication Payload into protocol specification that
5231 is used during SILC session to authenticate entities. It is
5232 used for example by client to authenticate itself to the server
5233 to obtain server operator privileges.
5235 Implemented this payload into the lib/silccore/silcauth.[ch].
5236 Implemented also routines for public key based authentication
5237 as the new protocol specification dictates.
5239 Moved definitions of different authentication methods from
5240 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5242 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5243 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5244 silc_pkcs_verify_with_hash functions into the file
5245 lib/silccrypt/silcpkcs.[ch].
5247 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * The client entry's userinfo pointer must be always valid.
5250 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5251 will fail since it requires the userinfo. Now, the userinfo
5252 is allocated as "" if actual userinfo does not exist. Actually,
5253 it must exist and it is totally Ok to drop client connections
5254 that does not announce the userinfo. However, we will make
5255 this workaround for now.
5257 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5258 to return the remote port by socket.
5260 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5263 SILC_SERVER_PENDING_EXEC and added an new macro
5264 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5265 data or when error occurs while processing the pending command.
5267 Added new argument `destructor' into silc_server_command_pending
5268 and to the SilcServerCommandPending object. This destructor is
5269 now called after calling the pending callback or if error occurs
5270 immediately. If error occurs the actual pending callback won't
5271 be called at all - only the destructor. The destructor may be
5272 NULL if destructor is not needed.
5274 All this applies for client library code as well. Similar
5275 changes were made there as well for the pending commands.
5277 In the client, the application must now allocate the
5278 SilcClientCommandContext with the silc_client_command_alloc
5281 * Added reference counter to the SilcServerCommandContext. Added
5282 function silc_server_command_alloc and silc_server_command_dup
5285 Same type of functions added to the client library for the same
5288 * Removed the cmd_ident from IDListData away since it is now
5289 global for all connections. It is the command identifier used
5290 in command sending and with pending commands. The affected file
5293 * Added reference counter to the SilcSocketConnection objecet to
5294 indicate the usage count of the object. The object won't be
5295 freed untill the reference counter hits zero. Currently only
5296 server uses this, and client ignores it. The client must be
5297 set to use this too later. The affected files are
5298 lib/silccore/silcsockconn.[ch]. Added also the function
5299 silc_socket_dup to increase the reference counter.
5301 This was mainly added because it is possible that the socket
5302 is removed underneath of pending command or other async
5303 operation. Now it won't be free'd and proper DISCONNECTING
5304 flags, etc. can be set to avoid sending data to connection that
5305 is not valid anymore.
5307 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5308 the connection. After that it sets SILC_SET_DISCONNECTED.
5309 It is, however, possible that the socket data is not still freed.
5310 The silc_server_packet_process now checks that data is not
5311 read or written to connection that is DISCONNECTED. The socket
5312 get's freed when the reference counter hits zero.
5314 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Changed the client operation API: channel_message operation's
5317 `sender' is now the client entry of the sender, not the nickname
5318 and the `channel' is the channel entry, not the channel name.
5320 In the private_message operation the `sender' is now also the
5321 client entry of the sender not the nickname.
5323 Affected file is lib/silcclient/ops.h and all applications
5324 using the client operations.
5326 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Moved the calling of ops->connect() from connect_to_server_final
5329 into receive_new_id functin since that is the point when the
5330 client is actually allowed to send traffic to network. The
5331 affected file is lib/silcclient/client.c.
5333 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5336 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5337 (if needs broadcasting) instead of broadcasting the packets one
5338 by one which would make a burst in the network traffic.
5340 * Added `broadcast' argument to the functions in silcd/server.[ch]
5341 silc_server_create_new_channel[_with_id] to indicate whether
5342 to send New Channel packet to primary router.
5344 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added new function into the silcd/server.[ch] files:
5347 silc_server_create_new_channel_with_id to create new channel with
5348 already existing Channel ID.
5350 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5351 lib/silccore/silcpacket.h. This packet is used t send list of
5352 Set Mode payloads inside one packet. Server uses this to set
5353 the modes for the channels and clients on those channels, that it
5354 announced to the router when it connected to it. The protocol
5355 specification has been updated accordingly.
5357 * The silc_server_new_channel did not handle the packet coming
5358 from normal server as it normally does not send that. However,
5359 when it announces its channels it does send it. Implemented
5360 the support for that.
5362 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5363 into the file lib/silccore/id.h.
5365 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5367 * Fixed memory leaks in the functions silc_idlist_del_client,
5368 silc_idlist_del_channel and silc_idlist_del_server in the file
5369 silcd/idlist.c. All of those leaked like a sieve.
5371 * Fixed some small memory leaks in the client's function
5372 silc_client_notify_by_server.
5374 * Added functions into silcd/server.c: silc_server_announce_clients,
5375 silc_server_announce_channels and silc_server_announce_server.
5376 These functions are used by normal and router server to announce
5377 to its primary router about clients, channels and servers (when
5378 router) that we own. This is done after we've connected to the
5381 These functions effectively implements the following packet types:
5382 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5383 and SILC_PACKET_NEW_ID_LIST.
5385 * Added new functions into the silcd/packet_receive.[ch]:
5386 silc_server_new_id_list, silc_server_new_channel_list and
5387 silc_server_new_channel_user_list to handle the incoming
5388 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5390 * Added support of changing Channel ID in the function
5391 silc_server_replace_id. If the server that announces a channel
5392 to the router already exists in the router (with same name but
5393 with different Channel ID), router is responsible to send
5394 Replace ID packet to the server and force the server to change
5395 the Channel ID to the one router has.
5397 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5398 client that the Channel ID has been changed by the router. The
5399 normal server sends this to the client. Client must start using
5400 the new Channel ID as the channel's ID.
5402 Implemented handling of this new type into lib/silcclient/client.c
5403 into the function silc_client_notify_by_server.
5405 * Added new function silc_idlist_replace_channel_id into the files
5406 silcd/idlist.[ch] to replace the Channel ID.
5408 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Call silc_server_command_identify_check always when processing
5411 the IDENTIFY command in silcd/command.c
5413 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5416 send keepalive packets. The packet can be sent by clients,
5417 servers and routers.
5419 Added function silc_socket_set_heartbeat into the file
5420 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5421 If not set, the heartbeat is not performed. The actual
5422 heartbeat is implemented in the low level socket connection
5423 library. However, application is responsible of actually
5426 Added silc_server_send_heartbeat to send the actual heartbeat
5427 packet into silcd/packet_send.[ch]. Server now performs
5428 keepalive with all connections.
5430 * Added silc_task_get_first function into lib/silcutil/silctask.c
5431 to return the timeout task with shortest timeout. There was a bug
5432 in task unregistration that caused problems. TODO has been
5433 updated to include that task system must be rewritten.
5435 * The client library will now resolve the client information when
5436 receiving JOIN notify from server for client that we know but
5437 have incomplete information.
5439 * Rewrote parts of silc_server_remove_from_channels and
5440 silc_server_remove_from_one_channel as they did not remove the
5441 channel in some circumstances even though they should've.
5443 * Encryption problem encountered in server:
5445 The LEAVE command used to send the Channel Key packet to the
5446 router immediately after generating it. However, the code
5447 had earlier sent Remove Channel user packet but not immediately,
5448 ie. it was put to queue. The order of packets in the router
5449 was that Channel Key packet was first and Remove Channel User
5450 packet was second, even though they were encrypted in the
5451 reverse order. For this reason, MAC check failed. Now, this
5452 is fixed by not sending the Channel Key packet immediately but
5453 putting it to queue. However, this is more fundamental problem:
5454 packets that are in queue should actually not be encrypted
5455 because packets that are sent immediately gets encrypted
5456 actually with wrong IV (and thus MAC check fails). So, packets
5457 that are in queue should be encrypted when they are sent to
5458 the wire and not when they put to the queue.
5460 However, the problem is that the current system has not been
5461 designed to work that way. Instead, the packet is encrypted
5462 as soon as possible and left to the queue. The queue is then
5463 just purged into wire. There won't be any fixes for this
5464 any time soon. So, the current semantic for packet sending
5467 o If you send packet to remote host and do not force the send
5468 (the packet will be in queue) then all subsequent packets to the
5469 same remote host must also be put to the queue. Only after the
5470 queue has been purged is it safe again to force the packet
5473 o If you send all packets immediately then it safe to send
5474 any of subsequent packets through the queue, however, after
5475 the first packet is put to queue then any subsequent packets
5476 must also be put to the queue.
5478 Follow these rules and everything works fine.
5480 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Added new function silc_server_remove_clients_by_server to
5483 remove all client entries from ID list when the server connection
5484 is lost. In this case it is also important to invalidate all
5485 client entires as they hold the invalid server entry. This
5486 fixes fatal bug when server has lost connection and will reconnect
5489 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * Made some sanity checks to silc_server_daemonise like to check
5492 whether the requested user and group actually exists.
5494 * Added sanity check to SKE's silc_ske_responder_finish to check
5495 that the public and private key actually is valid.
5497 * Invalidate the client's nickname when receiving Replace ID
5498 packet and the Client ID is being replaced. This means that the
5499 server will query the nickname if someone needs it (client)
5502 * Sort the ID Cache in client library when the ID Cache data
5503 has changed (needs sorting).
5505 * Do not allow for SILC client to create several connections to
5506 several servers. The client does not support windows right now
5507 and generating multiple connections causes weird behaviour.
5509 Irssi-silc client does support windows and can handle several
5510 connections without problems, see: www.irssi.org and SILC plugin.
5512 * Fixed some places where client was added to the IDList. The
5513 rule of thumb is following (in order to get everything right):
5514 If the client is directly connected local client then the
5515 `connection' argument must be set and `router' argument must be
5516 NULL to silc_idlist_add_client function. If the client is not
5517 directly connected client then the `router' argument must
5518 bet set and the `connection' argument must be NULL to the
5519 silc_idlist_add_client function.
5521 * The funtion silc_server_packet_send_local_channel actually did
5522 not check whether the client was locally connected or not. It
5523 does that now. Fixed a bug related to LEAVE command.
5525 * Fixed Remove Channel User payload parsing bug in server's
5526 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5528 * The server's silc_server_save_channel_key now checks also the
5529 global ID list for the channel as it might not be in the local
5530 list. Fixed a bug related to LEAVE command.
5532 * Is this the end of the [<unknown>] buglet that has been lurking
5533 around for a long time? A little for loop fix in server's
5534 silc_server_command_whois_parse that is used by both IDENTIFY
5535 and WHOIS command. At least, this was a clear bug and a cause
5536 of one type of [<unknown>] buglet.
5538 * WHOIS and IDENTIFY commands call the function
5539 silc_server_command_[whois/identify]_check function even if
5540 we are not router server.
5542 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Added --with-gmp configuration option. If set the GMP
5545 is always compiled in the SILC source tree. If not set then
5546 it is checked whether the system has the GMP3 installed. If
5547 it has then the GMP won't be compiled (the system's headers
5548 and library is used), if it doesn't have it then the GMP is
5549 compiled in the SILC source tree.
5551 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Changed RSA private exponent generation to what PKCS #1
5554 suggests. We try to find the smallest possible d by doing
5555 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5556 not security fix but optimization.
5558 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Added new config entry [Identity] to fork the server and run
5561 it as specific user and group. A patch from Bostik.
5563 * Imported Dotconf configuration library into lib/dotconf.
5564 This will be used to create the SILC configuration files later.
5565 It will appear in the distsribution after this commit.
5567 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * A big code auditing weekend happening. Auditing code for
5570 obvious mistakes, bugs and errors. Also, removing any code
5573 Removed files for being obsolete:
5575 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5576 inline in the file lib/silcutil/silcbuffer.h)
5578 o lib/silcutil/silcbufutil.c (the header has inline versions)
5580 Changed code to fix possible error conditions:
5582 o The buffer formatting routines now check that the destination
5583 buffer really has enough space to add the data. This applies for
5584 both buffer formatting and unformatting
5585 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5586 unformatting was changed to accomodate following rules:
5587 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5588 sent to the function while XXX_*STRING will not allocate or copy
5589 the data into the buffer. Instead it sets the pointer from the
5590 buffer into the pointer sent as argument (XXX_*STRING used to
5591 require that the pointer must be allocated already). This change
5592 makes this whole thing a bit more consistent and more optimized
5593 (note that the data returned in the unformatting with XXX_*STRING
5594 must not be freed now). The routines return now -1 on error.
5596 o Tried to find all code that use buffer_format and buffer_unformat
5597 and added return value checking to prevent formatting and
5598 especially unformatting errors and possible subsequent fatal
5601 o Changed ske->x and ske->KEY to mallocated pointers in
5602 lib/silcske/silcske.h. Fixed possible data and memory leak.
5604 o Added return value checking to all *_parse* functions. Fixed
5605 many memory leaks as well.
5607 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5608 so that buffer overflows would not happen. All code now also
5609 checks the return value as it can fail.
5611 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Added reconnection support to server if the normal server looses
5614 its connection to the router (for example if router is rebooted).
5615 The server performs normal reconnection strategy implemented
5616 to the server. Affected file silcd/server.c.
5618 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added new packet type SILC_PACKET_SET_MODE that is used to
5621 distribute the information about changed modes (for clients,
5622 channels and clients channel modes) to all routers in the
5623 network. Updated the protocol specification accordingly.
5625 Added functions into silcd/packet_send.c and
5626 silcd/packet_receive.c: silc_server_send_set_mode,
5627 silc_server_set_mode.
5629 Added new files silcmode.[ch] into lib/silccore that implements
5630 the encoding and decoding of Set Mode Payload. Added new type
5631 SilcSetModePayload. Moved the definitions of different modes
5632 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5634 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Oops, a little mistake in server's connection authentication
5637 protocol. The protocol is not ended with FAILURE but with
5638 SUCCESS if the authentication is Ok. :) Affected file is
5641 * Implemented NICK_CHANGE notify handling in server in the file
5642 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5643 the local clients on the channel. After the changing nickname
5644 in router environment snhould work and the [<unknown>] nickname
5645 should appear no more.
5647 The silc_server_replace_id function that receives the Replace ID
5648 payload now sends the NICK_CHANGE notify type also in the file
5649 silcd/packet_receive.c
5651 * Changed WHOIS and IDENTIFY command to support the maximum amount
5652 of arguments defined in protocol specs (3328 arguments). This
5653 fixed a bug that caused problems when there were more than three
5656 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added extra parameter, command identifier, to the
5659 silc_client_send_command so that explicit command identifier
5662 Changed that ID list routines uses specific command identifier
5663 when sending WHOIS/IDENTIFY requests to the server so that they
5664 can be identified when the reply comes back.
5666 Affected files lib/silcclient/command.[ch],
5667 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5669 * Added `sender' argument to silc_server_packet_send_to_channel
5670 to indicaet the sender who originally sent the packet to us
5671 that we are now re-sending. Ignored if NULL. Affected file
5672 silcd/packet_send.[ch].
5674 * Added some server statistics support in silcd/server_internal.h
5675 SilcServerStatistics structure and around the server code. Also
5676 send some nice statistics information when client is connecting
5679 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Fixed channel ID decoding in server's JOIN command reply in
5682 silcd/command_reply.c
5684 * Fixed braodcasting of replace ID payload to not to send it if
5685 we are standalone server in silcd/packet_receive.c.
5687 * Fixed all channel message sending routines to not to send
5688 packets to clients that has router set, since they are routed
5689 separately in the same function earlier. Affects file
5690 silcd/packet_send.c and all channel packet sending functions.
5692 * In USERS reply, res_argv[i] are not allocated, the table
5693 is allocated. Thus changed that free the table, not its
5696 * In server's whois_check and identify_check if the client is
5697 locally connected do not send any WHOIS commands - they are not
5700 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Fixed some minor bugs in client when sending WHOIS command. The
5703 arguments was in wrong order.
5705 * Removed statis function add_to_channel from server in
5706 silcd/command.c that was previously used with the joining but
5709 * Tested USERS command in router environment successfully with two
5710 routers, two servers and two clients.
5712 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Reorganized the USERS command and command reply in client library
5715 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5716 When the command is given by user we register a pending command
5717 callback that will reprocess the command after the reply has been
5718 received from the server. When reprocessing the packet we then
5719 display the information. Thus, the USERS information is displayed
5720 now in the command callback instead of in the command reply
5721 callback. The processing of the command is same as previously
5722 when server has sent the command reply in the JOINing process.
5724 * Added to USERS command in silcd/command_reply.c to join the client,
5725 we didn't use to know about, to the channel after we've created
5726 a client entry for it. Also, for clienet we did know already still
5727 check whether it is on the channel or not and add it if not.
5729 * Removed silc_server_command_join_notify as the function and its
5732 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5734 * Changed the client's pending command handling to the same as the
5735 server's pending command handling. It is also now possible to
5736 execute command reply functions from other command reply
5737 function as the function callbacks for commands and command
5738 replies are one and same. The pending commands are not static
5739 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5740 in client connection context. Thus, pending commands are server
5741 connection specific as it is convenient.
5743 Changed the function silc_client_command_pending and
5744 silc_client_command_pending_del and added new function
5745 silc_client_command_pending_check. Removed the
5746 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5749 * Added cmd_ident, current command identifier, to the client
5750 connection context in lib/silcclient/client.h to keep track on
5751 command identifiers used in command sending. Client's command reply
5752 function handling now supports the mandatory command identifiers.
5754 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5755 funtions in client to fully support pending command callbacks.
5757 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5758 as one of the arguments to the application in the command reply
5761 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5762 before first releasing SILC but came back. Now it is removed again
5763 and should come back nomore. The FORWARDED flag was used only
5764 by the JOINing procedure by forwarding the command packet to router.
5765 Now, the JOINing procedure has been changed to more generic (due
5766 to various router environment issues) and FORWARDED is not needed
5767 anymore for anything. The protocol specification is yet to be
5770 Now, removed silc_server_packet_forward from server and the flag
5771 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5773 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Renamed NAMES command to USERS command. The NAMES was named that
5776 due to historical reasons. Now it is renamed. Also, rewrote
5777 parts of the USERS command. The nickname list is not sent anymore
5778 by the server. Only Client ID and mode lists are sent in the USERS
5779 command. Changed this also to the protocol specification.
5781 The client now resolves the names and stuff after it receives
5782 the USERS list from the server when joining to the channel.
5784 * WHOIS and IDENTIFY commands has been changed to support multiple
5785 Client ID's per command. One can now search for multiple users
5786 in the network by sending only one WHOIS or IDENTIFY command.
5787 Changed the code and the protocol specifications.
5789 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5790 uses silc_server_command_whois_parse to parse the request. */
5792 * If normal server, do not parse the WHOIS and IDENTIFY requests
5793 before sending it to the router. Saves some time.
5795 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Fixed JOIN command on client library. Wrong number of arguments
5798 used to crash the client.
5800 * Added silc_server_channel_has_global function to check whether
5801 channel has global users or not.
5803 * Added silc_server_channel_has_local function to check whether channel
5804 has locally connected clients on the channel.
5806 * The silc_server_remove_from_one_channel now checks whether the
5807 channel has global users or not after given client was removed from
5808 the channel. It also checks whether the channel has local clients
5809 on the channel anymore. If it does not have then the channel entry
5810 is removed as it is not needed anymore.
5812 * The silc_server_notify now checks on JOIN notify whether the joining
5813 client is one of locally connected or global. If it is global then
5814 the channel has now global users on the channel and that is marked
5815 to the channel entry. Also, it now saves the global client to
5816 global list who is joining and JOINs it to the channel. This is
5817 for normal server, that is.
5819 Changed silc_server_send_notify_on_channel,
5820 silc_server_packet_relay_to_channel and
5821 silc_server_packet_send_to_channel check if we are normal server
5822 and client has router set (ie. global client) do not send the
5823 message to that client, as it is already routed to our router.
5825 * Implemented LEAVE notify type handling in silc_server_notify
5828 * Tested LEAVE command in router environment successfully. Tested
5829 with two routers, two servers and two clients.
5833 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5835 * Implemented SIGNOFF notify type handling in silc_server_notify
5838 * silc_server_remove_id now removes the client entry from all channels
5839 it has joined and thusly sends SIGNOFF notify type.
5841 * Rewrote the NAMES list generation in server by removing two excess
5842 loops. The lists are created now inside one loop.
5844 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * silc_server_remove_channel_user checks now also global list
5847 for channel and client.
5849 * silc_server_new_channel_user checks now both local and global
5850 list for channel and client. Fixed a bug in client id decoding.
5851 Used to decode wrong buffer.
5853 * silc_server_channel_message checks now both local and global
5854 list for channel entry.
5856 * Tested channel joining (hence JOIN) in router environment
5857 successfully. Tested with two routers, two servers and two
5860 * Tested channel message sending in router environment successfully.
5862 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Added silc_server_save_channel_key into server.[ch] to save the
5865 received channel key in Channel Key payload processing. It is
5866 also used in JOIN command reply handling.
5868 Equivalent function silc_client_save_channel_key added into
5869 client.[ch] into client library.
5871 * Changed JOIN command reply to send information whether the channel
5872 was created or not (is existing already) and the channel key
5873 payload. Changed protocol specs accordingly.
5875 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5876 the request was sent by ID and not by nickname. Crashed on
5879 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5882 now correctly save the received data.
5884 * silc_server_free_sock_user_data now notifies routers in the
5885 network about entities leaving the network.
5887 At the same time implemented functions silc_server_remove_id
5888 and silc_server_send_remove_id to receive and send REMOVE_ID
5889 packets. The packet is used to notify routers in the network
5890 about leaving entities. The ID removed will become invalid in
5893 * Added function silc_idlist_del_server into server. Removes and
5894 free's server entry from ID list.
5896 * silc_server_private_message function now checks, if we are router,
5897 that the destination ID really is valid ID, naturally.
5899 * In router when NEW_ID packet is received (for new client) the
5900 hash of the Client ID is saved in the ID Cache but the
5901 client->nickname is set to NULL, instead of putting the hash
5904 IDENTIFY command now also checks that client->nickname must be
5905 valid. If it is not if will request the data from the server who
5906 owns the client. Added new function
5907 silc_server_command_identify_check.
5909 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5910 to set the command to already allocated Command Payload.
5912 * Tested private message sending in router environment with two
5913 routers, two servers and two clients. Fixed minor bugs and now
5916 * Fixed segfault from client's NAMES command. Used to crash if
5919 * Forwarded packets must not be routed even if it is not destined
5920 to the receiver. Changed server code comply with this.
5922 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Added `require_reverse_mapping' boolean value to ServerParams
5925 structure. If TRUE (not default) the server will require that
5926 the connecting host has fully qualified domain name.
5928 If the reverse mapping is not required and hostname could not be
5929 found the IP address is used as hostname.
5931 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Implemented version string checking to both client and server.
5934 The check is incomplete currently due to the abnormal version
5935 strings used in development version of SILC.
5937 * Changed all command functions in server to use the new
5940 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Changed char *data to unsigned char *data in ID Cache system to
5943 support binary data as ID Cache data. Changed code to support
5944 binary data in lib/silccore/idcache.c.
5946 * Renamed silc_server_packet_relay_command_reply to
5947 silc_server_command_reply as it is normal packet receiving
5948 function. Rewrote the function to accept command replys for
5949 servers and not only for clients.
5951 * Mark remote router always as registered server if we are connecting
5952 to it. Otherwise, commands sent by the router to us are ignored.
5954 * All ID List find routines now returns the ID Cache Entry pointer
5955 as well if requested.
5957 * WHOIS command works now in router environment, tested with two
5958 routers, two servers and two clients.
5960 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5961 in router environment (as it is almost equivalent to WHOIS) but
5962 hasn't been tested thoroughly. Added new functions:
5964 silc_server_command_identify_parse
5965 silc_server_command_identify_send_reply
5966 silc_server_command_identify_from_client
5967 silc_server_command_identify_from_server
5969 * Disabled route cache adding because adding two different ID's with
5970 same IP replaces the old cache entry thus giving wrong route.
5971 The entry->router->connection is always the fastest route anyway
5972 so route cache may not be needed. Of course, new routes maybe
5973 established after receiving the ID when the entry->router->connection
5974 might not be anymore the most optimal.
5976 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5978 * Add route cache for received ID for fast routing.
5980 * Added silc_server_packet_route to route received packet on router
5981 that is not destined to us.
5983 * Renamed silc_server_get_route to silc_server_route_get.
5985 * Added id_string and id_string_len fields into SilcServer to
5986 include encoded ServerID for fast comparing without excess
5987 encoding of the ID's.
5989 * Cleaned up WHOIS command on server side. Added following static
5992 silc_server_command_whois_parse
5993 silc_server_command_whois_check
5994 silc_server_command_whois_send_reply
5995 silc_server_command_whois_from_client
5996 silc_server_command_whois_from_server
5998 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5999 arguments in command replies. All command functions should be
6000 updated to use this macro.
6002 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6004 * Minor typo fixes on command reply handling on server.
6006 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added silc_server_command_add_to_channel internal routine to add
6009 the client to the channel after router has created the channel and
6010 sent command reply to the server.
6012 * Added generic silc_server_send_command to send any command from
6015 * Use static buffer with ID rendering instead of duplicating data.
6017 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Fixed a channel user mode bug when joining to a channel server gave
6020 everybody channel founder rights, oops.
6022 * We mark ourselves as the router of the incoming server connection
6023 if we are router ourselves. This way we can check in some packet
6024 sending functions whether it is locally connected server. For
6025 incoming router connections we put NULL.
6027 * For router sending packets locally means now always sending the
6028 packet cell wide; to local clients and local servers. For normal
6029 server sending packet locally means sending it to only local
6032 * Fixed the JOIN command to really work in router environment. If the
6033 channel is created it is always created by the router. Router is
6034 also responsible of making the initial joining to the channel,
6035 sending JOIN notify to the sending server and distributing
6036 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6037 does not exist server doesn't do anything else but forward the
6038 command to the router which performs everything.
6040 * Added silc_server_send_channel_key function to send the Channel Key
6043 * Added silc_server_create_channel_key to create new channel key. The
6044 channel key is now re-generated everytime someone joins or leaves
6045 a channel, as protocol dictates. Note: channel->key_len is the
6048 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6051 packet_receive.[ch] to separate packet sending and receiving
6052 routines. The server.[ch] now includes everything else including
6053 actual packet processing (writing and reading data) and other
6056 Renamed silc_server_private_message_send_internal to
6057 silc_server_send_private_message. The routine is still though
6058 used only to relay private messages as server does not send
6059 private messages itself.
6061 Renamed silc_server_new_channel to silc_server_create_new_channel
6062 and added new function sicl_server_new_channel that handles the
6063 incoming New Channel packet. Added also new sending function
6064 silc_server_send_new_channel to send New Channel Payload.
6066 * Added new function silc_server_notify to process incoming notify
6067 packet to the server/router. Server may then relay the notify
6068 to clients if needed.
6070 * Added new function silc_server_new_channel_user to process incoming
6071 New Channel User packet. Router will redistribute the packet and
6072 send JOIN notify to its local clients and locally connected servers
6073 if needed. Normal server will send JOIN notify to its local client
6074 on same channel when received this packet. Added also corresponding
6075 sending function silc_server_send_new_channel_user to sent the
6078 * Added boolean route argument to send_notif_to_channel and
6079 packet_send_to_channel functions to attempt to route the packet
6080 if it is TRUE and send only locally if it is FALSE.
6082 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6084 * silc_server_replace_id now broadcasts the received replace ID
6085 packet if it is not broadcast packet already. The router must
6086 broadcast to inform other routers about changed ID.
6088 * Added backpointer to server's router into SilcServer context in
6089 silcd/server_internal.h.
6091 * Fixed silc_server_packet_broadcast to send correct broadcast
6094 * The channel key is now distributed to the local client as soon
6095 as it is received from the router (in router environment) so that
6096 no other packet may be sent for the channel until client has
6099 * silc_server_remove_channel_user now broadcasts the received
6100 Remove Channel User packet if it is not broadcast packet already.
6101 The router must broadcast to inform other routers about removed
6104 * Added users field into SilcPacketContext that is a reference count
6105 of the context. One can increase the reference count by calling
6106 silc_packet_context_dup which is now changed to just increase the
6107 reference count instead of duplicating the data. The reference
6108 count is decresed by calling silc_packet_context_free that will
6109 free the data after the reference count hits zero.
6111 For now on the packet context and everything allocated into it
6112 (including the raw packet from network) must be freed by calling
6113 the new silc_packet_context_free function. Added also new function
6114 silc_packet_context_alloc that must be used now to allocate the
6115 context. This also means that if a routine is asynchronous from
6116 silc_[client/server]_packet_parse_type the packet context must
6117 be duplicated by calling silc_packet_context_dup. Otherwise it
6118 gets free'd after silc_[client/server]_packet_parse_type returns.
6119 Also, one must remember that if packet is duplicated then its
6120 reference count must be decresed by calling the free function as
6121 many times as it was duplicated.
6123 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6124 from both client and server.
6126 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Made joining to a channel working in router environment.
6130 * Cleaned up JOIN command on server side and create function
6131 silc_server_command_join_channel internal routine to make the
6134 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Changed silc_command_pending list to SilcDList. Also, added
6137 `ident' field to SilcServerCommandPending structure to identify
6138 the reply and to call correct callback.
6140 Added silc_server_command_pending_check function to replace the
6141 corresnponding macro. The silc_command_pending list is not
6144 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6145 to set identifier to previously allocated Command Payload. It
6146 is used to set identifier for command when resending Command
6149 * Added silc_command_payload_encode_payload to encode Command
6150 Payload buffer from SilcCommandPayload structure.
6152 * Added silc_argument_payload_encode_payload to encode Argument
6153 payload buffer from SilcArgumentPayload structure.
6155 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Changed WHOIS command to support router connection on server side.
6158 The whois request is always sent to router unless the server is
6159 standalone server. After server has received the reply from the
6160 router will it send the reply to the client.
6162 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6163 broadcast received broadcast packet. The function is used only
6164 by router. The broadcast packet is always sent to the router's
6167 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6168 render given ID to printable string, for log files for example.
6170 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Made basic router to router connections working. At least they
6173 can now connect to each other but nothing really works the way
6174 they are supposed - yet.
6176 * Added new initiator token to RouterConnection configuration
6177 file in silcd/serverconfig.[ch]. It is used to tell whether we
6178 are the initiator to the remote router or whether we'll expect
6179 the other end to connect.
6181 * Moved registering of listener task to silc_server_init, hence
6182 the server starts listenning as soon as it is run, even if it
6183 does not have connections to other routers. Let's see how well
6186 * Changed default connection retry timeouts for more suitable in
6189 * Removed cipher and such arguments from silc_idlist_add_client
6190 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6191 Added new function silc_idlist_add_data to add the keys and stuff
6194 * Added SilcIDListData structure and added it to SilcClientEntry
6195 and SilcServerEntry as their first field in the structure. This
6196 way we can explicitly cast the ID entries to the SilcIDListData
6197 structure and get common data for the entries. In past, we had
6198 to first check what type of connection it is and then cast it to
6199 correct ID entry type. Now, we can directly cast the opaque
6200 pointer to the SilcIDListData (no matter what ID entry it actually
6201 is) and get the data needed.
6203 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6206 in some circumstances even if threre were timeout tasks, though not
6207 IO tasks, but tasks anyway. Now fixed.
6209 * Defined SilcServerConnection structure to hold connection specific
6210 stuff about directly connected servers and routers. The definition
6211 is currently in silcd/server_internal.h. I thought about having
6212 a bit more important role fro this struct but for now it is used
6213 only when connecting to other server (or router actually).
6215 * Added connecting retry support in server when connecting to
6216 router(s). The retry feature implement exponential backoff
6217 algorithm. Also, added SilcServerParams structure to hold default
6218 parameters for server. For now, it include these retry settings
6219 and are hard coded. After server is moded to be as Silc Server
6220 Library this structure will be more important.
6222 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Changed client librarys channel->clients table to SilcList and
6225 changed code accordingly.
6227 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Changed client's channel table to SilcList and changed code
6230 accordingly. Also changed SilcChannelClientEntry to include back-
6231 pointer to the channel so that client entry can use that structure
6232 as list as well and we have fast cross-reference to the channel.
6233 This change dramatically decreased the complexity of channel
6234 handling with client entry and vice versa (removed one extra
6235 loop when searching for channel entry from many functions).
6237 * Changed server->sim from table to SilcDList and changed code
6240 * NAMES command can now be used from user interface. It will show
6241 the user list on the channel, neatly.
6243 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6244 Code now saves realname of the user if it becomes available.
6246 * Renamed configure.in to configure.in.pre and made ./prepare
6247 script to automatically add correct version string to
6248 configure.in which it creates from configure.in.pre.
6250 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * NAMES command reply now shows users mode with the nickname when
6255 * Moved silc_client_ch[u]mode[_char] functions from
6256 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6257 place sucks, they are utility functions and should be in some
6260 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6262 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6265 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Added TRQ (efficient deque and list library) into lib/trq. This is
6270 a very good list library that is currently used in the SILC. Defined
6271 SilcList API over the library because I didn't like the API very
6272 much. See lib/trq/silclist.h for the API and examples of how to
6273 use the API. Fixed various places in the code to use the new
6274 SilcList API. The SilcList is meant for lists that has a structure
6275 already defined as a list. It is not suitable to add just some
6276 context to the list (in TRQ, the context is the list actually).
6278 So, I defined SilcDList that can be used for the purpose where
6279 predefined list structure does not exit. This can be used as
6280 such list. Now some context just can be added to the SilcDList.
6281 Currently this list is not used in the SILC just yet, though there
6282 are a lot places where this can replace dynamically allocated
6283 tables and I will fix these places, later, to use SilcDList.
6284 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6285 and use TRQ internally).
6287 Also fixed some annoying warning messages that the original TRQ
6288 code generated. Also minor changes to TRQ's Makefile.in.
6290 * Added support for querying by Client ID to both WHOIS and
6291 IDENTIFY commands into server, as required by the protocol.
6293 * Removed method function pointers from SilcBuffer structure. They
6294 weren't used to anything and just increased the context size for
6295 no good reason. This change also made silc_buffer_alloc and
6296 silc_buffer_free functions inline functions.
6298 * Disabled command flooding detection support until it's fixed so
6299 that it accepts commands in but does not execute them more than once
6302 * Added silc_net_localhost(), to return local hostname, into
6303 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6304 that must be initialized before calling silc_client_init.
6306 * Added new function: silc_server_send_notify_on_channels to send
6307 notify messages to all channels client has joined. It is assured
6308 that the message is sent only once per client.
6310 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6311 lib/silcutil/silcutil.[ch] as silc_format function. The new
6312 function is generic and is used by server as well, not only by
6313 the logging routines.
6315 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6316 the provided version string was not acceptable. Added new function:
6317 silc_ske_check_version into lib/silcske/silcske.h. The function
6318 must be implemented by the application (client or server) and it
6319 does not reside in the SKE library. The function checks the version
6320 string remote end sent.
6322 * Added back pointers (to opaque context and to SilcSocketConnection)
6323 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6325 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6326 duplicate packet context structure.
6328 * Changed `notify' client operation to send same arguments as client
6329 receives from server except for ID's. ID's are mapped to correct
6330 ID entry and that is returned. Also, if channel entry is not sent
6331 by server but the notify is for channel the channel entry is sent
6332 to application (otherwise application doesn't know that it is for
6333 channel (library gets it from packet's Destination ID)).
6335 * Added silc_client_remove_from_channels into client library to
6336 remove a client from all channels it has joined to. Used when
6337 received SIGNOFF notify from server. Added also new function
6338 silc_client_replace_from_channels to replace old ID entry with
6339 new ID entry on all channels. Used when received NICK_CHANGE
6342 * Fixed ID Cache list handling in silc_idlist_get_client in
6343 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6344 to get (or query) client by ID.
6346 * Updated TODO list.
6348 * Added connection authentication status message defined by the
6349 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6350 support for these into the code in client and server side.
6352 * Added generic function silc_client_send_command to send any command
6353 with variable argument list. Application should use this function
6354 to send commands if the command functions provided by the library
6355 does not suite for the application's user interface needs.
6357 * Added new `failure' client operation. Application is notified about
6358 received failure packet if client is executing a protocol. In this
6359 case the protocol's execution has failed.
6361 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6362 is required by the protocol.
6364 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6365 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6368 * Added status flag to SilcSKE object to indicate realtime status
6369 of the SKE protocol.
6371 * Application receives now exactly same command reply arguments as
6372 the library receives from server. However, if ID is received the
6373 corresponding ID entry is returned to the application (eg. Client
6374 ID is mapped to correct SilcClientEntry entry and that is returned).
6375 Changed command_reply client operation due to this change.
6377 * Changed all ID's in commands and in command replys as ID Payloads.
6378 Change affected both client and server side codes.
6380 All ID's sent in SILC network (with execption of ID's in SILC
6381 Packet header) are sent in ID Payload to support variable length
6384 * Server now notifies nick changes and notifies all clients on
6385 the channels about the new nickname (about the new Client ID,
6388 * Implemented CMODE command to change channel modes. Supports all
6389 channel modes defined by the protocol specs except ban and invite
6390 lists. (Also, private channel key mode is supported but support for
6391 setting private channel key in client is missing, thus, this mode
6392 has no effect on client side (except that server requires that the
6393 client uses private channel key and normal channel traffic does not
6396 Also, invite mode works per se, but INVITE command does not work
6397 yet correctly, so you can set channel as invite only channel but
6398 inviting clients to the channel does not work (it is yet to be
6399 thought what's the best way to do it).
6401 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6402 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6403 Implemented CUMODE command to change user's mode on the channel.
6404 Supports all modes defined by the protocol specs.
6406 * Added NAMES command reply to return users modes on the channel.
6408 * Removed unnecessary and slow ciphers from lib/silccrypt.
6410 * Set SO_KEEPALIVE option to connection sockets by default.
6412 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6414 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6415 redefined the Notify Payload into protocol specs.
6417 * Added silc_id_payload_parse_id to get ID directly from raw
6420 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6423 accept searching by Client ID as well.
6425 * Added support for LEAVE and SIGNOFF notify types in client library.
6427 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6428 to parse ID Payload from raw data.
6430 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Added flags parameter into silc_ske_assemble_security_properties
6433 function in lib/silcske/silcske.[ch].
6435 * Changed notify client operation to fit better for notify messages
6436 sent by server. The notify payload received from server is now
6437 passed to the application (after parsing it to SilcNotifyPayload).
6438 It is application's responsibility to retrieve the arguments
6439 from the payload and show the message the way it wants. The message
6440 sent by server is implementation specific.
6442 * Changed public keys to comply with the protocol specification.
6443 Old public keys are not supported anymore and are not compatible.
6445 * Removed nickname from Channel Payload as the latest draft removed
6446 it. The client must resolve the nickname from the NAMES command
6447 reply received when it joined the channel.
6449 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6451 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6453 * Fixed some errors in protocol specification drafts.
6455 * Created lib/silccore/silcnotify.c to implement Notify Payload
6456 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6457 generic payloads described by protocol specifications. The file
6458 includes implementations for ID Payload and Argument Payload.
6460 * Changed Command Payload implementation to use the new Argument
6461 Payload. Changed command_xxxx_payload to command_payload_xxxx
6462 to comply with SILC coding conventions.
6464 * Added suppport for Argument Payload handling in Notify Payload
6465 implementation as protocol requires it. Added the new support
6466 into server and client lib as well.
6468 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Added support for multiple nicknames on same channel. [n] is
6471 added locally to the nickname if there are more than one same
6472 nicknames on the channel.
6474 * Server now sends all nicknames that matched WHOIS request.
6475 Client also shows the list received from server.
6477 * Added TOPIC command to client side. User can now set and show
6478 current topic on channel.
6480 * Added MOTD command to client and server. Also, server sends the
6481 motd when client connects to the server.
6483 * Changed version strings to comply ISO 8601.
6485 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Fixed protocol error handling in client library. It should now
6488 cope even if the SKE fails for some reason.
6490 * Made new protocol specification drafts for submitting to IETF.
6492 * Implemented TOPIC command to server in silcd/command.c.
6494 * Added two new notify types into lib/silccore/silcnotify.h:
6495 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6496 notify nickname change and topic setting/change on a channel.
6498 * API change of command_reply operation in client library. The
6499 application gets now the status type received from server as well.
6501 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6505 * Cras fixed and optimized the packet handling even further and
6506 it should work now. Minor change to the prototype of function
6507 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6509 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Added new function into lib/silcutil/silcschedule.[ch]:
6512 silc_schedule_with_fd to select() a specified fd. The function
6513 returns after timeout expires or data arrives or goes. The
6514 function is used by packet routines to wait that all data is
6515 received from network.
6517 * Fixed data reading from network in lib/silccore/silcpacket.c.
6518 The code now assures that all data is read from the fd and then
6519 continues packet processing. This was a bug fix since the code
6520 used to drop some data in some circumstances.
6522 * Added new function into lib/silcclient/client.[ch]:
6523 silc_client_start_key_exchange to start key exchange after
6524 connection has been established to server. The code internally
6525 now uses this funtion but its main purpose was to provide it
6526 for applications that perform their own connecting. After
6527 application has created a connection it merely calls this
6528 function to start the key exchange between client and server.
6529 The library takes care of everything else after that.
6531 Updated also lib/silcclient/README to explain the usage of
6534 * Do not send to application information that connection has
6535 been established. Application gets notified it by connect
6538 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6540 * Applied cras's patch to add silc_schedule_one function. The
6541 function runs scheduler once and returns.
6543 * Fixed the scheduler after cras messed it up. The timeout
6544 handling works now as it's supposed to work.
6546 * Added into lib/silccore/ silcnotify.h to include notify
6547 message types support. Changed silc_server_send_notify*
6548 functions, in server.[ch], to support those new notify types.
6549 Added the support for the notify types into client library,
6550 as well. Added new notify client operation into ops.h in
6553 * Changed silc_server_packet_send_to_channel to send normal
6554 packets instead of just channel message packets. The function
6555 is now used to send the notify packets to channels. It is not
6556 used to send channel message packets anymore, as server never
6559 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6560 va_arg()s as it seems to require it nowadays. I guess, if SILC
6561 is compiled with older va_arg() the new code should work anyway.
6563 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * Splitted core library. Core library (lib/silccore) includes
6566 now only SILC protocol specific core (and common) components.
6567 Created new utility library (lib/silcutil) that includes more
6568 generic purpose stuff. The stuff for util library was taken
6569 from the old core library. This was minor and easy split.
6571 * Created SILC Client Library (lib/silcclient) that includes
6572 implementation of the SILC client without user interface. This
6573 was major move from silc/ directory. The code has been changed
6574 so that it is transparent towards the user interface. The
6575 silc/ directory includes now the same user interface as before
6576 and it uses the new client library. Read lib/silcclient/README.
6577 Basicly, the client library performs everything else related
6578 to SILC except user interface handling. Also, configuration
6579 files are considered to be part of user interface and library
6580 does not handle them.
6582 This change also changed a lot of structures, function naming etc.
6583 Most important change was that SilcClientWindow object was
6584 renamed to SilcClientConnection in the client library. Created
6585 also new file lib/silcclient/ops.h. Also added new files
6586 silc/local_command.[ch] and silc/client_ops.[ch].
6588 All these changes were made to make it easier for user interface
6589 designers to create what ever user interface for the SILC client
6592 It is also expected that the server will be moved to lib
6593 directory as well and SILC Server Library will be created;
6594 sometimes in the future.
6596 * Removed Local commands from lib/silccore/silccommand.h as
6597 they are application specific and new client library does not
6598 handle any of those anymore.
6600 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6601 old client implementation in silc/.
6603 * Added support for callback functions in SILC_LOG_* macros.
6604 Application can now set its own callbacks that will be called
6605 instead of using the default functions that will always print
6606 the debug messages to stderr (or stdout). Also, debugging can
6607 now be disabled by setting silc_debug to FALSE and re-enabled by
6608 setting it to TRUE. Note, that logging will still work even
6609 if debugging is disabled.
6611 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6612 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6613 silc_log_reset_debug_callbacks.
6615 * To enable debugging in silc client one must give now -d
6616 option on command line.
6618 * Changed silc_schedule_init to automatically allocate task queues
6619 if they are not allocated before calling it.
6621 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * Added GMP 3.1 into math library.
6625 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6628 a channel in SILC network. The packet is used by servers and
6629 routers to notify other routers that user has left a channel.
6630 This little feature was missing until now. Added the feature
6631 to protocol specification as well.
6633 Added functions: silc_server_send_remove_channel_user and
6634 silc_server_remove_channel_user into server.[ch].
6636 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6637 lib/silccore/silcpacket.h. However, they are not implemented
6640 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Fixed joining to a channel and sending channel messages
6643 between server and router. The channel message sending should
6644 now work inside a cell.
6646 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Fixed the private message sending between server and router.
6649 The private message sending should now work inside a cell.
6651 * Added silc_server_replace_id into server.[ch] to replace
6652 existing ID in the SILC network.
6654 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6655 and silc_idlist_replace_server_id into idlist.[ch] in server.
6657 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Fixed the server to server connections. Server can again now
6660 connect to router. Router to router connections probably does
6663 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Added dynamic protocol registering support. Now protocols can
6666 registered and unregistered on the fly. Patch by cras.
6668 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Added lib/contrib directory to hold routines that some platforms
6671 don't have but are needed by SILC.
6673 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6674 into lin/contrib to provide getopt() and getopt_long() for
6675 those who don't have it.
6677 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6679 * Added AWAY command to client. When away message is set and
6680 client receives a private message packet the client automatically
6681 replies to the sender with the away message.
6683 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6684 bug seemed to be the cause of recent problems when compiling
6687 * Added version detection support to SKE protocol specification
6688 and added the new changes to the SKE implementation as well.
6689 There were other minor changes in the SKE protocol as well.
6691 Many changes in lib/silcske/silcske.[ch] and in
6692 lib/silcske/payload.[ch].
6694 * Added ^U functionality, clear input line. Patch from cras.
6696 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Mainly small bugfixes on core library. Fixed some debugging
6699 logging and buffer overflow in silclog.c.
6701 * Updated config.sub and config.guess on the distribution tree.
6703 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Added command lagging support in server. Client may execute
6706 commands now only once in two seconds.
6708 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Optimized packet reception. MAC computation and checking is now
6711 also more optimized. A lot previously duplicated code is now
6712 used as generic by both client and server.
6714 * Fixed key pair generation in clientutil.c
6716 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Added into lib/silccore/silcbufutil.[ch] new function;
6719 silc_buffer_realloc.
6721 * Moved generic packet sending/encryption functions to
6722 lib/silccore/silcpacket.[ch] from client and server. Some
6723 rewriting of the functions.
6725 * Moved all generic packet reception/decryption functions to
6726 lib/silccore/silcpacket.[ch] from client and server. The
6727 packet processing is now much cleaner in both client and server.
6728 These were major changes in both client and server.
6730 * Created many common functions in server to do packet sending.
6731 Previously code were duplicated a lot, this has been removed
6734 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Rewrote major parts of the ID cache system. Don't know
6737 whether it is better now or not but at least the API is more
6740 * Major rewrite on ID cache stuff on client because of the ID
6741 cache API changes. Added idlist.c to client.
6743 * Also major rewrite on ID cache stuff on server as well.
6744 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6745 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6746 in hand, instead they are all put into the ID cache system now.
6747 All server_idlist_* routines uses ID cache now instead of
6748 traversing its own lists (those lists does not exist anymore).
6749 SilcIDList though still exists. Also, SilcXXXEntry's are
6752 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Finally made the SKE implementation compliant to the protocol
6755 specification. All mp integers are now binary encoded as
6756 opposed being HEX encoded.
6758 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6761 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6762 functions: silc_[encode/decode]_pem. Also added function
6763 silc_encode_pem_file to PEM encode with newlines ('\n') for
6766 * SILC public keys are now encoded either PEM or binary. Same
6767 option is for private keys as well. By default private keys
6768 are binary encoded and public keys PEM encoded. Silly HEX
6769 encoding were removed.
6771 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6772 function to create fingerprints.
6774 * Fixed a bug in SHA1; does not change the original data anymore.
6776 * Partly implemented INFO command on client and server side.
6777 Fixed CLEAR command. Changes to SERVER command; show current
6778 server(s) when giving command without arguments. Added
6779 VERSION command to client.
6781 * Added check to server that unregistered connections cannot
6782 execute commands (unless it is specificly allowed).
6784 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Fixed screen refresh.
6788 * Fixed channel joining bug from client. On some circumstances
6789 client tried to join to a channel it had already joined.
6791 * Added public key verification process into client's protocol.c.
6792 The client now verifies the public key from user and saves
6793 it into ~./silc/serverkeys/ directory.
6795 Added into: clientutil.[ch]: silc_client_verify_server_key.
6797 * Changed SKE protocol's silc_ske_initiator_finish function
6798 to accept callback function that verifies the received public
6799 key. Removed old silc_ske_verify_public_key function.
6801 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6804 silc_pkcs_private_key[_data]_set.
6806 * Made the password and public authentication more cleaner in
6807 server's protocol.c.
6809 * Removed historic and obsolete protocol `channel_auth' from
6810 both client and server.
6812 * Removed wrong way of sending command status messages from
6813 server to client in server's command.c. The old way violated
6814 protocol specification.
6816 Changes to silccore/silccommand.[ch]: removed
6817 silc_command_encode_status_payload -> not needed anymore,
6818 changed silc_command_encode_payload_va to accept extra
6819 argument on variable argument list. The argument type must
6820 now be provided to the function. Also, added new function:
6821 silc_command_encode_reply_payload_va which is same as
6822 normal command_encode_payload_va except command status type
6823 is provided as extra argument.
6825 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6827 * Added ~./silc directory handling. The directory includes the
6828 public and private keys for the client.
6830 Added silc_client_check_silc_dir, silc_client_create_identifier
6831 and silc_client_load_keys.
6833 * Implemented SILC protocol compliant public key. Added public
6834 and private key saving to and loading from files.
6836 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6837 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6838 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6839 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6840 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6842 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6843 silc_pkcs_load_[public/private]_key.
6845 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Added silc_server_get_route (route.[ch]) to get connection
6848 data for the fastest route for given ID.
6850 * Implemented INVITE command on client and server. The command
6851 were re-defined in the SILC Protocol Specification and the
6852 implementation now complies with the specification.
6854 * Implemented PING command on client and server.
6856 * Implemented NAMES command on client and server. The server side
6857 supports currently only normal server not router server yet.
6858 Some changes to NAMES definition in SILC protocol specification.
6860 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Implemented LEAVE command on client and server.
6864 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6865 again. This change was made to the protocol as well. Server
6866 should not violate the protocol specification anymore.
6868 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6871 was tested. SOCKS4 was not but should work anyway.
