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

587 and a little WHOIS problem.
589 * Fixed silc_net_gethostbyname to correctly call the
590 inet_ntop. Affected file lib/silcutil/silcnet.c.
592 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
594 * Added IPv6 support checking to the configure.in.pre, added
595 also --enable-ipv6 option to override the check. Affected
596 file configure.in.pre.

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

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

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

779 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
781 * Use ++server->cmd_ident when sending commands in server,
782 instead of random number. Affected file silcd/command.c.
784 * Fixed GETKEY command reply to call actually GETKEY pending
785 command callbacks. Affected file silcd/command_reply.c.
787 * A bit stricter check for nicknames. Check for same nickname
788 in NICK command also. Affected file silcd/command.c.
790 * Do not call INFO command everytime client ID changes, only
791 during first connecting. Affected file lib/silcclient/client.c.
793 * Set the new nickname only after successful command reply for
794 NICK command is returned by server. Affected file
795 lib/silcclient/command.c.
797 * Remove nicknames from nicklist during server_signoff notify.
798 Should fix /NAMES bit more. The affected file is
799 irssi/src/silc/core/silc-channels.c.
801 * Added `fingerprint' field to the SilcIDListData in the
802 silcd/idlist.h to hold the fingerprint of the client's
805 Send the fingerprint of the client's public key in WHOIS
808 Affected files silcd/command.c, and silcd/idlist.[ch].
810 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
811 create fingerprint from given data.
813 * Show the fingerprint of the client's public key in WHOIS.
814 Affected files irssi/src/module-formats.[ch] and
815 irssi/src/silc/core/client_ops.c.
817 * Format the multiple same nicknames also during JOIN and
818 NICK_CHANGE notifys. Affected file is
819 lib/silcclient/client_notify.c.
821 * Do not print error on screen for invalid private message
822 payload since it can come if someone is sending private
823 messages with wrong key. Affected file
824 lib/silccore/silcprivate.c.
826 * Fixed multiple concurrent /PING crash. Affected file
827 lib/silcclient/command.c.
829 * Changed the wrong ID encoding. All IP addresses must be
830 in MSB first order in encoded format. They were encoded
831 wrong and was in LSB format. Affected files are
832 silcd/serverid.c, lib/silcutil/silcutil.c.
834 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
836 * Call the `connect' client operation through the scheduler
837 in case of error. Affected file lib/silcclient/client.c.
839 * Call the `failure' client operation even if the error
840 occurred locally during a protocol. Affected file is
841 lib/silcclient/protocol.c.
843 * Added support of sending LIST command to router from normal
844 server. This way normal server can get list of all channels
845 in the network too. Fixed the channel list sending in the
846 server too. Affected files are silcd/command.c, and
847 silcd/command_reply.[ch].
849 * Added silc_server_update_channels_by_server and
850 silc_server_remove_channels_by_server. They are used during
851 disconnection of primary router and in backup router protocol.
852 Affected file silcd/server_util.[ch], silcd/server.c and
853 silcd/server_backup.c.
855 * Fixed channel adding to global list in IDENTIFY command
856 reply in server. Affected file silcd/command_reply.c.
858 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
860 * If the incoming packet type is REKEY or REKEY_DONE process
861 that packet always synchronously. Fixes yet another MAC
862 failed error on slow (dialup) connections. Affected file
863 lib/silcclient/client.c and silcd/server.c.
865 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Call check_version SKE callback for initiator too. Affected
868 file lib/silcske/silcske.c.
870 * Implemented fix for security hole found in the SKE that was
871 fixed in the specification few days back; the initiator's
872 public key is now added to the HASH value computation.
873 Added backwards support for the old way of doing it too, for
874 old clients and old servers. Affected file is
875 lib/silcske/silcske.c.
877 * Enabled mutual authentication by default in SKE. If initiator
878 is not providing mutual authentication the responder will
879 force it. This will provide the proof of posession of the
880 private key for responder. The affected files are
881 lib/silcclient/protocol.c and silcd/protocol.c.
883 * Do not cache anymore the server's public key during SKE.
884 We do mutual authentication so the proof of posession of
885 private key is done, and if the server is authenticated in
886 conn auth protocol with public key we must have the public
887 key already. Affected file silcd/protocol.c.
889 * Added new global debug variable: silc_debug_hexdump. If
890 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
891 file lib/silcutil/silclog.[ch].
893 * Fixed compilation warning due to char * -> const char *.
894 Affected files lib/silcutil/silcnet.h, and
895 lib/silccore/silcauth.[ch].
897 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
899 * Fixed CMODE command when new channel key was created. If
900 the creation failed the old key was removed. Next time giving
901 same command would crash the server since the old key was
902 freed already. Affected file silcd/command.c.
904 * Fixed the silc_server_announce_get_channels to not crash
905 on reconnect. Affected file silcd/server.c.
907 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
909 * Added silc_log_set_debug_string function to set a regex
910 string to match for debug output. Only the function names,
911 or filenames matching the given debug string is actually
912 printed. This way it is possible to filter out those debug
913 strings that user is not interested in.
915 Fixed a bug in silc_string_regexify.
917 Affected files lib/silcutil/silclog.[ch], and
918 lib/silcutil/unix/silcunixutil.c.
920 * Changed the -d options in both server and Irssi SILC client
921 to take the debug string as argument. Affected files
922 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
924 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
926 * Added silc_hash_babbleprint to create a Bubble Babble
927 Encoded fingerprint. The encoding is developed by Antti
928 Huima (draft-huima-babble-01.txt), and it creates human
929 readable strings out of binary data. Affected file
930 lib/silccrypt/silchash.[ch].
932 * Print the babble print now in addition of fingerprint as well
933 in Irssi SILC client. Affected files are
934 irssi/src/fe-common/silc/module-formats.[ch],
935 irssi/src/fe-common/silc/core/client_ops.c.
937 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Fixed a security problem found in SKE. The initiator's
940 public key too is now added to the HASH hash value creation
941 which is signed by the responder to create the SIGN value.
942 This will prevent anyone in the middle to lie to the responder
943 about the initiator's public key. If this is done now, the
944 man in the middle will get caught. Updated the protocol
947 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
949 * Better installation directory handling. Configure module
950 paths and other paths automatically to example_silc* files
951 in doc/. A patch by toma.
953 * Fixed compiler warning from MPI library, and from SILC RNG.
956 * Added SILC_SERVER_PID_FILE to define the pid file for server.
957 It can be configured with ./configure. A patch by toma.
959 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Find correct make to use in prepare-clean. A patch by
962 toma. Affected file prepare-clean.
964 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
966 * Added irssi variables use_auto_addr, auto_bind_ip,
967 auto_bind_port and auto_public_ip.
969 * Changed the interface for silc_client_send_key_agreement
970 in lib/silcclient/silcapi.h
974 irssi/src/silc/core/silc-core.c
976 lib/silcclient/silcapi.h
977 irssi/src/silc/core/silc-channels.c
978 lib/silcclient/client_keyagr.c
981 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
983 * Added silc_pkcs_public_key_compare to compare two
984 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
986 * Check that the client who set the founder mode on the
987 channel is the same client that is giving the founder
988 mode to itself. It is done by comparing the saved public
989 key (it is saved even in the authentication is passphrase).
990 Affected file silcd/command.c.
992 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Do not process packet for disconnected socket connection.
995 Affected file lib/silccore/silcpacket.c.
997 * Process the DISCONNECT packet through scheduler in the
998 client library. Affected file lib/silcclient/client.c.
1000 * Fixed the silc_client_packet_parse to not to increase
1001 the packet sequence number if the conn->sock and the
1002 current socket connection is not same. This can happen
1003 for example during key agreement when the conn includes
1004 multiple socket connections (listeners). Affected file
1005 lib/silcclient/client.c.
1007 * The sender of the file transfer request now provides also
1008 the pointer (listener) for the key exchange protocol. If
1009 the listener cannot be created then it sends empty key
1010 agreement and lets the receiver provide the listener.
1012 Added `local_ip' and `local_port' arguments to the
1013 silc_client_file_send. If they are provided they are used,
1014 if not then it will attempt to find local IP address, if
1015 not found or bind fails then the remote client will provide
1018 Affected files are lib/silcclient/client_ftp.c and
1019 lib/silcclient/silcapi.h.
1021 * Extended the FILE SEND command to support defining the
1022 local IP and port for key exchange listener. They are
1023 optional. Affected file irssi/src/silc/core/silc-servers.c.
1025 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1027 * Defined to WHOIS command reply the sending of fingerprint
1028 of the client's public key (if the proof of posession of the
1029 corresponding private key is verified by the server).
1030 Updated to the protocol specification.
1032 * Added support of receiving the client's public key's
1033 fingerprint in command reply in client library. Affected
1034 file is lib/silcclient/command_reply.c, and
1035 lib/silcclient/idlist.[ch].
1037 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1039 * Do not send over 128 chars long nickname to the server
1040 in NICK command. Affected file lib/silcclient/command.c.
1042 * Do not send over 256 chars long channel names to the server
1043 in JOIN command. Affected file lib/silcclient/command.c.
1045 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Assure that silc_server_close_connection cannot be called
1048 twice for same socket context. Affected file is
1051 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1053 * Send error message to application if opening file for
1054 writing during file transfer fails. Affected file is
1055 lib/silcclient/client_ftp.c.
1057 Remove all file transfer sessions for a client that we're
1058 removing from ID cache.
1060 Affected file is lib/silcclient/client_ftp.c.
1062 * Fixed silc_net_addr2bin to return correct address. Affected
1063 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1065 * Fixed file transfer session removing on signoff notify.
1066 Affected file irssi/src/silc/core/silc-servers.c.
1068 * Added the SilcClientFileError to be returned in the monitor
1069 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1070 Affected file lib/silcclient/silcapi.h.
1072 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Fixed a crash in silc_client_ftp_free_sessions and
1075 silc_client_ftp_session_free_client. Affected file
1076 lib/silcclient/client_ftp.c.
1078 * Added `disabled' field in the SilcChannelEntry in the server
1079 to indicate if the server entry is disabled. Affected file
1080 silcd/idlist.h, silcd/command[_reply].c.
1082 * SILC server adds now /var/run/silcd.pid everytime it is
1083 started. Affected file silcd/silcd.c.
1085 * Added silc_server_packet_send_clients to send a packet to
1086 the provided table of client entries. Affected file
1087 silcd/packet_send.[ch].
1089 * Fixed a crash in client resolving in client_prvmsg.c in
1090 client library. Affected file lib/silcclient/client_prvmsg.c.
1092 * Do not actually remove the client directly from ID cache
1093 during SERVER_SIGNOFF, but invalidate it. This way we
1094 preserve the WHOWAS info for the client. Affected file
1095 silcd/server_util.c.
1097 * Fixed SERVER_SIGNOFF notify handling in the server. The
1098 server is now able to process incoming SERVER_SIGNOFF notify
1099 for a server that it doesn't even know about. It will remove
1100 the clients provided in the notify. Affected file
1101 silcd/packet_receive.c.
1103 * Check for partial packet in data queue after every packet that
1104 was found from the queue. Return and wait for more data if
1105 there is partial data in queue. Affected file is
1106 lib/silccore/silcpacket.c.
1108 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1110 * Added SilcClietFileError enum to indicate error in
1111 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

1116 * Check that newsize in silc_buffer_realloc is larger than
1117 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1119 * Added better monitor of file transfers. It now monitors
1120 key agreement protocol during the file transfer too. Added
1121 error reporting too. Affected files
1122 irssi/src/silc/core/silc-servers.c,
1123 irssi/src/fe-common/silc/module-formats.[ch].
1125 * Wrote a help file for FILE command.
1127 * Added silc_rng_global_get_byte_fast to get not-so-secure
1128 random data as fast as possible. Random data is read from
1129 /dev/urandom if available and from the SILC RNG if not
1130 available. It is used in padding generation. Affected file
1131 lib/silccrypt/silcrng.[ch].
1133 * All packets in client library are now processed synchronously.
1134 Optimized packet processing a lot. Affected file
1135 lib/silcclient/client.c.

1138 now in server, to optimize packet processing. Affected file
1141 * Include files are installed now only in Toolkit distribution
1142 if make install is given. Affected files: all Makefile.am's.
1144 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1146 * Assure that silc_client_notify_by_server_resolve does not
1147 resolve the client information multiple times. If it cannot
1148 be found by the first it cannot be found at all. Affected
1149 file lib/silcclient/client_notify.c.
1151 * Fixed WHOWAS command reply calling. Affected file
1152 lib/silcclient/command_reply.c.
1154 * Removed all references to silc_idlist_get_client from the
1155 Irssi SILC client since that call is internal call used by
1156 the library. The Irssi SILC client will use now client
1157 retrieval functions found in silcapi.h.
1159 * Fixed a bug in resolving nickname info before sending
1160 private message. It used freed memory. Affected file
1161 irssi/src/silc/core/silc-servers.c.
1163 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * Assure my_channels statistics cannot go negative in server.
1166 Affected files silcd/server.c, silcd/server_util.c.
1168 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1182 * Added silc_net_localip to return local host's IP address.
1183 Affected file lib/silcutil/silcnet.[ch].
1185 * If key exchange or rekey protocol is active for a connection
1186 parse all packets syncronously since there might be packets
1187 in packet queue that we are not able to process without first
1188 processing packets before them. Affected file silcd/server,
1189 lib/silcclient/client.c.
1191 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1192 whether library should continue processing the packet.
1193 Affected file lib/silccore/silcpacket.h.
1195 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1224 lib/silcutil/silcutil.[ch].
1226 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Resolve the client info when received private message or
1229 channel message for a client which nickname we don't know.
1230 Affected files lib/silcclient/client_prvmsg.c and
1231 lib/silcclient/client_channel.c.
1233 * Do not crash in /KEY if client is not connected. Affected
1234 file irssi/src/silc/core/silc-channels.c.
1236 * Added SilcClientStatus field to the SilcClientEntry in the
1237 lib/silcclient/idlist.h.
1239 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1240 is incomplete and is being resolved, it won't be resolved
1243 Make sure also that USERS command reply does not resolve
1244 twice information. Affected file is
1245 lib/silcclient/command_reply.c.
1247 Make sure that silc_client_get_clients_by_list does not
1248 resolve twice same information.
1250 * Check for valid client->id in the silc_server_free_client_data.
1251 Affected file silcd/server.c.
1253 * Fixed /GETKEY nick@server not to crash if the server entry
1254 is not found. Affected file lib/silcclient/command.c.
1256 * Fixed the silc_server_check_cmode_rights to check the
1257 requested modes correctly. Affected file silcd/command.c.

1261 * Better checks for non-printable chars in nick added.
1262 Affected file silcd/command.c.
1264 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Call the silc_server_udpate_servers_by_server in the
1267 primary router that comes back online in the backup resuming
1268 protocol. Otherwise it routes packets wrong. Affected file
1269 silcd/server_util.[ch], silcd/server_backup.c.
1271 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1274 lib/silcutil/silcbuffmt.[ch].
1276 * Redefined the SILC packet header to include the padding
1277 length. Affected file lib/silccore/silcpacket.[ch].
1279 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1280 length for maximum padding up to 128 bytes). Affected
1281 file lib/silccore/silcpacket.h.
1283 * Removed all backwards support for old 0.5.x MAC thingies.
1284 The SILC packet header change makes it impossible to be
1285 backwards compatible.
1287 * Send the ENDING packet with timeout in the backup resuming
1288 protocol. This is to assure that all routers has connected
1289 to the primary router. Affected file silcd/server_backup.c.
1291 * Changed the RNG to take the first IV from random data. It
1292 used to take it from zero actually. Changed the RNG also
1293 to use /dev/urandom during session. /dev/random is used
1294 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1296 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Changed the SILC packet header to have the first two bytes
1299 (the packet length) encrypted. Affected files aroung the
1300 code tree, lib/silccore/silcpacket.[ch]. Removed the
1301 SilcPacketCheckDecrypt callback. It is not needed anymore
1302 since the silc_packet_receive_process will determine now
1303 whether the packet is normal or special.
1305 * Implemented the unidirectional MAC keys. Affected files
1306 lib/silcske/silcske.c, silcd/protocol.c and
1307 lib/silcclient/protocol.c.
1309 * Implemented the packet sequence number to the MAC computation.
1310 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1311 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1312 lib/silcclient/protocol.c.
1314 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Allow backup router to announce servers. All servers
1317 announced by backup router are added to the global list
1318 automatically. Update hte server's socket to our primary
1319 router also when backup router announces a server.
1320 Affected file silcd/packet_receive.c.
1322 * Do not update the client->router in the function
1323 silc_server_udpate_clients_by_server if the client is on
1324 global list. We might fail to find any specific server
1325 for locally connected clients and local cell clients. They
1326 should still use the `from' and not `to' as client->router.
1327 This fixes backup router resuming protocol. Affected file
1328 silcd/server_util.c.
1330 * Decrease channel statistics count only if the channel
1331 deletion worked. Affected files are silcd/server.c and
1332 silcd/server_util.c.
1334 * Added silc_server_update_servers_by_server to update origin
1335 of all server entries. Used during backup router protocol.
1336 Affected files silcd/server_util.[ch], silcd/server.c. and
1337 silcd/backup_router.c.
1339 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1340 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1341 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1342 lib/silccrypt/silchmac.c.
1344 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Assure that router cannot reroute the same channel message
1347 to the sender. Affected file silcd/packet_receive.c.
1349 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Made better checks that the channel message is not sent
1352 to the router it came from. Affected file is
1353 silcd/packet_send.c. Fixed memory leak too.
1355 * Announce informations for incoming router connection, but
1356 only after checking if it is replaced by backup router.
1357 Affected file silcd/packet_receive.c.
1359 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1361 * Fixed the backup resuming protocol to work in multiple
1362 router environment. Affected file silcd/server_backup.c.
1364 * Route packet only to one router in the function
1365 silc_server_packet_send_to_channel. Affected file is
1366 silcd/packet_send.c.
1368 * Fixed silc_server_send_notify_dest to set the broadcast
1369 flag. Fixed the silc_server_send_notify_topic to actually
1370 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1371 Affected file silcd/packet_send.c.
1373 * Changed the SFTP Filesystem interface. Changed the
1374 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1375 the filesystem operation function. The SilcSFTPFilesystem
1376 is now a context that is allocated by all filesystem allocation
1377 functions and it already includes the operations structure
1378 and filesystem specific context. It is given as argument
1379 now to the silc_sftp_server_start. This made the interface
1380 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1381 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1383 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Changed the backup router adding and getting interfaces
1386 in the server. The router that will be replaced by the
1387 specified backup router is now sent as argument. Affected
1388 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1391 * Added silc_net_addr2bin_ne to return the binary form of
1392 the IP address in network byte order. Affected files
1393 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1395 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1397 * Check for existing server ID in silc_server_new_server
1398 and in silc_server_connect_to_router_final and remove the
1399 old entry if it exists. Affected file silcd/packet_receive.c,
1402 * Send the channel message always to only one router, either
1403 in upstream or downstream. Affected file is
1404 silcd/packet_send.c.
1406 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Wrote the definition of the backup resuming protocol to the
1409 protocol specification.
1411 * Removed one redundant channel key generation from normal
1412 server during joining procedure. Removed one redundant
1413 channel key sending from server to router during joining
1414 procedure. Affected file silcd/command.c.
1416 * Made minor bugfixes to the backup router resuming protocol.
1417 Affected file silcd/server_backup.c, server.c.

1421 * Added --disable-asm configuration option. Affected files
1422 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1425 * Implemented the backup resuming protocol that is used to
1426 resume the primary router position in the cell after the
1427 primary router comes back online. Affected files
1428 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1429 and silcd/server_util.[ch].
1431 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1433 * Sleep two (2) seconds after sending QUIT command to server.
1434 Affected file lib/silcclient/command.c.
1436 * Assure that if outgoing data buffer is pending do not force
1437 send any data. Affected file silcd/packet_send.c.
1439 * Assure that if outgoing data buffer is pending do not force
1440 send any data. Affected file lib/silcclient/client.c.
1442 * Implemented the backup router support when the primary router
1443 goes down. The servers and routers can now use the backup
1444 router as new primary router without loosing connectivity.
1446 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1449 in the server to indicate disabled entry. All data read
1450 from the connection will be ignored and no data is sent
1451 for entry that is disabled. Affected files are
1452 silcd/idlist.h, silcd/server.c.
1454 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Created SFTP client and server test programs in the
1457 lib/silcsftp/tests directory.
1459 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Implemented memory filesystem (virtual filesystem) for
1462 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1465 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Implemented the SFTP (SSH File Transfer Protocol) to the
1468 lib/silcsftp. It includes SFTP client and SFTP server
1471 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Moved lib/silccore/silcprotocol.[ch] to the
1474 lib/silcutil library.
1476 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1477 take variable argument list pointer as argument. Affected
1478 file lib/silcutil/silcbuffmt.[ch].
1480 * Added silc_buffer_set function that is used to set data
1481 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1482 Affected file lib/silcutil/silcbuffer.h.
1484 * Changed various routines in the core library to use the new
1485 silc_buffer_set instead of allocating new buffer only for
1488 * Added 64-bit value formatting and unformatting support to the
1489 silc_buffer_[un]format routines. Affected file is
1490 lib/silcutil/silcbuffmt.[ch].
1492 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1493 to includes/bitmove.h.
1495 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Fixed channel user mode saving in client library. Affected
1498 file lib/silcclient/command[_reply].c.
1500 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Defined the file transfer to the SILC Protocol. Added
1503 new packet type SILC_PACKET_FTP and defined File Transfer
1504 Payload. The mandatory file transfer protocol is SFTP
1505 (SSH File Transfer Protocol). Affected file in addition
1506 of the internet draft is lib/silccore/silcpacket.h.
1508 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1509 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1510 is used as part of backup router protocol when the primary
1511 router of the cell is back online and wishes to resume
1512 the position as primary router.
1514 * Redefined the MAC generation keys in the protocol. The
1515 same key is not used anymore in both direction. Both
1516 direction will now use different keys for sending and
1517 receiving. This fixes a potential security flaw. This
1518 change causes incompatibilities in the protocol.
1520 * Redefined also the MAC computation from the packet.
1521 An packet sequence number is now added to the MAC
1522 computation. This prevents possible replay attacks against
1523 the protocol. This change too causes incompatibilities
1526 Added `sequence' field to the SilcPacketContext to hold
1527 the current sequence number for the packet.
1529 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Added `created' field to the SilcIDListData in the file
1532 silcd/idlist.h to indicate the time when the entry was
1535 * Added `created' field to the SilcChannelEntry too. Affected
1536 file silcd/idlist.h.
1538 * Added `creation_time' aguments to all the announcement functions
1539 in the server. If it is provided then only the entries that
1540 was created after the provided time frame are actually
1541 announced. Affected file silcd/server.[ch].
1543 * The protocol says that the Channel ID's IP address must be
1544 based on the router's IP address. Added check for this in
1545 the silc_server_new_channel when processing incoming New Channel
1546 Payload. Affected file silcd/packet_receive.c.
1548 * Print out the correct version with --version in SILC client.
1549 Affected file irssi/src/silc/core/silc-core.c.
1551 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed WHOWAS command to check for completnes of the client
1554 entry always, not just when the command is coming from client.
1555 Affected file silcd/command.c.
1557 * Added new function silc_server_packet_queue_purge to purge the
1558 outgoing data queue to the network. After the function returns
1559 it is guaranteed that the outgoing packet queue is empty.
1560 Affected file silcd/packet_send.[ch].
1562 * Purge the outgoing packet queue in the rekey protocol's final
1563 callback to assure that all rekey packets go to the network
1564 before quitting the protocol. Affected file silcd/server.c.
1566 * Added silc_client_packet_queue_parse as similar function as
1567 in server to the client library. The affected file is
1568 lib/silcclient/client.c.
1570 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Splitted silcd/server.c and created silcd/server_util.[ch]
1573 for utility functions.
1575 * Added new socket flag SILC_SF_DISABLED to indicate that the
1576 connection is open but nothing can be sent to or received from
1577 the connection. Affected file lib/silcutil/silsockconn.[ch].
1578 The checking for disabled socket is checked in the low level
1579 silc_socket_write and silc_socket_read functions.
1581 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Allow only nicknames and channel names that fits into the
1584 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1586 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * When processing JOIN command reply in server check that if
1589 the channel exists in our global list we'll move it the local
1590 list. Affected file silcd/command_reply.c.
1592 * Fixed the check whether client is joined on the channel already
1593 in JOIN command. Affected file lib/silcclient/command.c.
1595 * Fixed the JOIN command reply to check whether the channel
1596 already exists. Affected file lib/silcclient/command_reply.c.
1598 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1600 * Added silc_ske_status_string to map the SKE error numbers
1601 to readable strings. The affected files are
1602 lib/silcske/silcske[_status].[ch].
1604 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Do not show the private channels on the WHOIS channel list
1607 as it is not allowed by the protocol. The affected file is
1610 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1612 * Assure that the packet length digged from the actual packet
1613 is something sensible in the silc_packet_decrypt_rest_special
1614 in lib/silccrypt/silcpacket.c.
1616 * Free and NULL the allocated pointer in silc_hmac_alloc if
1617 the HMAC allocation fails. The affected file is
1618 lib/silccrypt/silchmac.c.
1620 * Print the selected security properties to the log files in
1621 the server. Affected file silcd/protocol.c.
1623 * Add SKE's reference counter even if calling the completion
1624 callback manually. Otherwise it goes negative, although it
1625 does not cause any problems. The affected file is
1626 lib/silcske/silcske.c.
1628 * Remove the client entry with short timeout after giving the
1629 KILL command. Affected file lib/silcclient/command.c.
1631 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1632 case all found clients are already disconnected (WHOWAS would
1633 found them) in the server. Affected file silcd/command.c.
1635 * Update the last_receive (time of last data received) to be
1636 updated only when received private or channel message so that
1637 the idle time showed in WHOIS makes more sense.
1639 * Added boolean field `valid' in to the SilcClientEntry in the
1640 client library to indicate whether the entry is valid or not.
1641 This fixes the nickname change bug on channel when changing
1642 the nickname to be same than the old (like nick to Nick) the
1643 nickname formatter doesn't set the new nick anymore to Nick@host.
1644 Affected file lib/silcclient/idlist.[ch].
1646 * Now actually fixed the nickname changing on disconnection.
1647 Added new function silc_change_nick to the Irssi SILC Client.
1648 Affected file irssi/src/silc/core/client_ops.c,
1649 irssi/src/silc/core/silc-nicklist.[ch].
1651 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Check that the public key exists in the GETKEY command before
1654 trying to encode it. Affected file silcd/command.c.
1656 * Print some notifications on received public keys with GETKEY
1657 command in the Irssi SILC Client. Affected files are
1658 irssi/src/fe-common/silc/module-formats.[ch],
1659 irssi/src/silc/core/client_ops.c.
1661 * Use IDENTIFY command to resolve the server information in the
1662 GETKEY command instead of INFO command. Affected file
1663 lib/silcclient/command.c.
1665 * All command reply functions in the client library now calls
1666 the pending command reply callbacks even if an error has
1667 occurred. The server has done this a long time and now it was
1668 time to move the client library to this as well. Now all
1669 errors can be delivered back to the pending command reply
1670 callbacks if necessary. Affected files are
1671 lib/silcclient/command[_reply].[ch].
1673 * Change the nickname on disconnection back to the username
1674 because in reconnect the server will enforce it to it anyway.
1675 Affected file irssi/src/silc/core/silc-servers.c.
1677 * Fixed a config file parsing bug in the Irssi SILC client.
1678 Affected file irssi/src/silc/core/clientconfig.c.
1680 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * When printing the channel mode on JOIN, verify that the
1683 channel key and channel's HMAC are valid. Affected file
1684 irssi/src/silc/core/client_ops.c.
1686 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1689 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1690 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1692 * Removed channel key rekey task deleting from the function
1693 silc_server_save_channel_key. Affected file silcd/server.c.
1694 Added explicit timeout task context instead that is used to
1695 delete the task if we are registering a new task before the
1696 new task has elapsed.
1698 * When channel key rekey occurs the client library now saves
1699 the old channel key for a short period of time (10 seconds) and
1700 is able to use it in case some is still sending channel
1701 messages encrypted with the old key after the rekey. Affected
1702 file lib/silcclient/[idlist.h|client_channel.c].
1704 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1706 * Added check to the silc_server_new_id_real to not accept
1707 new ID if it is the sender's own ID. Affected file is
1708 silcd/packet_receive.c.
1710 * Assure that we do not announce ourself or the one we've
1711 sending our announcements when we're router and are announcing
1712 servers to our primary router. Affected file silcd/server.c.
1714 * Fixed silc_server_command_identify_check_client to assemble
1715 correct WHOIS packet. It send corrupted WHOIS packet and
1716 caused problem with router to router connections. Affected
1717 file silcd/command.c.
1719 Fixed also silc_server_command_whois_check the same way
1720 as for the IDENTIFY command.
1722 * Added new SilcIDListStatus to the server in the SilcIDListData
1723 structure. The status now includes the current status of
1724 the entry (like registered, resolved etc.). Affected file
1725 silcd/idlist.[ch]. Defined a bunch of different status types
1726 as well. This replaced the old boolean registered field as well.
1728 Added resolve_cmd_ident field to the SilcClientEntry structure
1729 too so that if the entry is for example being resolved so
1730 another command may attach to the same pending command reply
1731 without requiring to resolve the same entry again. This concept
1732 should optimize the WHOIS and the IDENTIFY resolving under
1733 heavy load by taking away unnecessary resolving for entries
1734 that are being resolved already.
1736 Added support for adding multiple pending commands for one
1737 command idenfier. Affected file silcd/command[_reply].[ch].
1739 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1740 before deleting the data. Otherwise the hash table will have
1741 freed data in comparison functions. Affected file is
1742 silcd/command_reply.c.
1744 * Fixed silc_idlist_replace_client_id to add the new entry to
1745 the cache with NULL nickname. Otherwise there will be invalid
1746 memory as the nickname after the nickname is freed. Affected
1747 file silcd/packet_receive.c.
1749 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1750 saved into wrong slots because the previous number of entries
1751 was not taken into account. Affected file silcd/idlist.c.
1752 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1754 * If we are router and we receive JOIN notify to a channel that
1755 does not have any users then notified client is marked as the
1756 channel founder, as it is it. The affected file is
1757 silcd/packet_receive.c
1759 * Added to the extended hash table API's table_del_*ext functions
1760 the destructor as argument too, so that the caller can decide
1761 which destructor to use or whether to use destructor at all.
1762 Affected file lib/silcutil/silchashtable.[ch].
1764 * Fixed ID Cache purging. It actually deleted the entries from
1765 the hash table after the data was freed. The hash table ended
1766 up comparing freed memory. The affected file is
1767 lib/silccore/silcidcache.c.
1769 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Fixed Irssi SILC client's KILL command's HELP syntax.
1773 * The USERS command now resolves the detailed user information
1774 if the userinfo field is missing. Affected file is
1775 lib/silcclient/command_reply.c.
1777 * Do not print error in silc_file_read if the read file does
1778 not exist. Just silently return NULL. Affected file is
1779 lib/silcutil/silcutil.c.
1781 * Fixed the silc_log_output to not wine about NULL filename
1782 and to not create some bogus " " filename. Affected file is
1783 lib/silcutil/silclog.c.
1785 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1787 * Fixed various printing bugs on the user interface in the
1788 Irssi SILC Client. Minor changes that were forgotten from
1791 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Fixed the configure.in.pre and the compilation and distribution
1794 environment to support the new autoconf 2.52. That version is
1795 now required to compile the CVS trunk.
1797 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1800 to generally parse user@fqdn format strings. Affected file
1801 lib/silcutil/silcutil.c.
1803 * Added nickname_format and nickname_force_format fields to the
1804 SilcClientParams structure. The first one defines the format
1805 for the nicknames that the library will enforce if the receives
1806 multiple same nicknames. The second one is boolean value and
1807 can be used to force the library to always enforce the format
1808 to the nicknames regardles whether there are multiple nicknames
1809 or not. This configurable formatting was employed to flexibly
1810 support accessing multiple nicknames from the user interface.
1811 The userinterface can now set the nicknames to what ever format
1812 they prefer. Affected file lib/silcclient/silcapi.h.
1814 Added function silc_client_nickname_format to the file
1815 lib/silcclient/idlist.c. It performs the nickname formatting.
1817 Added new field `hostname´ to the SilcClientEntry context.
1818 It holds the hostname of the client. Affected file is
1819 lib/silcclient/idlist.h.
1821 * Irssi SILC Client sets the nicknames in nick@hostn format.
1822 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1823 irssi/src/silc/core/silc-core.c.
1825 The WHOIS printing now also shows both the real nickname and
1826 the formatted nickname so that user knows how to access the
1827 user if there are multiple same nicknames cached. Affected
1828 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1829 printing formatting too to take the hostname now as a separate
1830 argument. The Affected file is
1831 irssi/src/fe-common/silc/modules-formats.[ch].
1833 * Changed the silc_client_get_clients_local to accept the formatted
1834 nickname as argument. It accepts the real nickname too but the
1835 formatted nickname can be used to find the true entry from
1836 multiple entries. Affected file lib/silcclient/silcapi.h and
1837 lib/silcclient/idlist.c.
1839 * Added nickname_format_parse field to the SilcClientParams.
1840 It is a callback function provided by the application to parse
1841 the nickname out of the formatted nickname string. The library
1842 calls it to get the nickname from the formatted string. Since
1843 the application generally knows better the format of the nickname
1844 string it parses it instead of the library, even though library
1845 encodes the formatted string. If the callback function is not
1846 provided then the library will use the string as is. The
1847 affected file is lib/silcclient/silcapi.h.
1849 * All the nickname strings passed to the client library in
1850 commands are now expected to be formatted nickname strings.
1851 If the command does not support the formatted nickname string
1852 it will assume that the sent string is the actual nickname.
1853 Affected file lib/silcclient/command.c.
1855 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Added public key authentication support to OPER and SILCOPER
1858 commands in the client library. Affected file is
1859 lib/silcclient/command.c.
1861 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Changed the get_auth_methdod client operation to be asynchronous.
1864 It can be async if the application resolves the authentication
1865 method from the server during the negotiation. Added new
1866 SilcGetAuthMeth completion callback that the application will
1867 call after resolving the authentication method.
1869 Added function silc_client_request_authentication_method that
1870 the application can use to resolve the authentication method
1871 from the server. Added also SilcConnectionAuthRequest callback
1872 that the library will call after the server has replied. The
1873 application can call this function if it does not know the
1874 current authentication method.
1876 Affected files are lib/silcclient/client.c and
1877 lib/silcclient/silcapi.h.
1879 * The Irssi SILC client now automatically resolves the authentication
1880 method incase any configuration information is not present (and
1881 currently there never is). The affected file is
1882 irssi/src/silc/core/client_ops.c.
1884 * Fixed public key authentication from the client library.
1885 Affected file lib/silcclient/protocol.c. Changed also the
1886 protocol specification about the public key authentication in
1887 the connection authentication protocol. The actual data to be
1888 signed is now computed with a hash function before signing.
1890 * Fixed the public key authentication from the server as well.
1891 Affected file silcd/protocol.c.
1893 * Removed the mlock()'s from the memory allocation routines.
1894 Affected file lib/silcutil/silcmemory.c. The ./configure does
1895 not check anymore for the mlock(). Affected file is
1898 * Fixed USERS command in server to allow the execution of the
1899 command for private and secret channels if the client sending
1900 the command is on the channel. Affected file silcd/command.c.
1902 * Fixed silc_client_get_clients_local to return the clients
1903 count correctly. It could return wrong value. Affected file
1904 lib/silcclient/idlist.c.
1906 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1909 types. The assembler optimizations seemed not to like 64-bit
1910 data types. The assmebler optimizations thus are now enabled
1911 also for BSD systems as opposed to only enable them for Linux.
1913 * Do not check for threads at all on BSD systems. Affected
1914 file configure.in.pre.
1916 * Removed -n and -h options from the Irssi SILC Client since
1917 they are not used in silc.
1919 * Fixed the prime generation to assure that the first digit
1920 of the generated random number is not zero since our conversion
1921 routines does not like number strings that starts with zero
1922 digit. If zero digit is seen the random number is regenerated.
1923 This caused some corrupted RSA keys when the zero first digit
1924 was met. Affected file lib/silcmath/silcprimegen.c.
1926 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Fixed WIN32 configuration in the ./configure script.
1929 Fixed to include xti.h on environments that has it.
1930 Patches by Carsten Ilchmann and andrew.
1932 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1934 * Changed the silc_id_create_client_id to be collision
1935 resistant. It is now assured that there cannot be created
1936 two same client ID's. I suspect that some weird bugs in
1937 the server were actually caused by duplicate Client IDs.
1938 Affected file silcd/serverid.[ch]. A router receiving
1939 new ID now also assures and informs the sending server
1940 if the ID caused collision.
1942 * Changed the silc_id_create_channel_id to also assure that
1943 there are no collisions.
1945 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * Statement about ignoring the Mutual Authentication flag when
1948 performing rekey with PFS was a bit misleading. It is ignored
1949 if it was set in the initial negotiation, it cannot be even
1950 set in the rekey. Fixed in the ke-auth draft. Started the
1951 new versions of the protocol drafts in the doc/.
1953 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * Fixed a bug in silc_client_command_identify_save when saving
1956 new channel information. The channel name was no duplicated
1957 and caused crash on exit. Affected file is
1958 lib/silcclient/command_reply.c.
1960 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Fixed the getkey command handling in the server. Send just
1963 empty OK reply to the sender if the key could not be fetched
1964 (but everything else was ok, like the key just was not available).
1965 Changed the public key parameter to optional in the protocol
1966 specs so that empty OK reply can be sent. Affected file
1969 Added a message to Irssi SILC client to tell to user if the
1970 server did not return a public key.
1972 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1974 * Fixed a channel key regeneration bug. It registered new
1975 timeout tasks exponentially until all system resources were
1976 used. Affected file silcd/server.c.
1978 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Added the SILC Document generator to the scripts/silcdoc.
1981 It can be used to generate the Toolkit Reference Manual out
1982 of the source tree. Internally it will also use the RoboDoc
1983 generator now imported in util/robodoc.
1985 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1987 * Added couple of return's in rekey protocol if error orccurred
1988 during the protocol. The execution must be terminated.
1989 Affected file silcd/protocol.c. Also, terminate the protocol
1990 always with timeout.
1992 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1994 * The client's Client ID was created initally from the wrong
1995 nickname (it could have been in format nick@host) in the
1996 silc_server_new_client. Affected file silcd/packet_receive.c
1998 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Added some SILC_LOG_ERROR's to various error conditions
2001 if client could not be added to ID cache. Affected files
2002 silcd/packet_receive.c and silcd/server.c.
2004 * When client's sock->user_data is freed, NULL also the
2005 client->router and client->connection pointers. Added check
2006 for these pointers being NULL to various places around the
2007 code. Affected file silcd/server.c.
2009 * Added client->data.registered == TRUE checks to various
2010 places around the code to assure that unregistered client's
2011 are not handled when it is not allowed. Affected file
2014 * Added `bool registered' fields to all
2015 silc_idlist_[server|client]_get_* routines to indicate whether
2016 the fetched client needs to be registered or not. Affected
2017 file silcd/idlist.[ch].
2019 * Add your own entry as registered to the ID cache in the
2020 server. Affected file server.c.
2022 * Fixed a bug in silc_server_new_server. The SilcServer was
2023 set as the new server's context instead of SilcServerEntry.
2024 This naturally caused some weird bugs.
2026 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Do not delete the channel rekey task when adding it
2029 for in silc_server_create_channel_key.
2031 * Changed the silc_server_create_channel_key to return
2032 TRUE or FALSE to indicate the success of the channel key
2035 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Fixed MSVC++ project files and added missing files to
2038 Makefiles under win32/.
2040 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Do not add TCP_NODELAY flag if the operating system
2043 does not have it defined. Affected files are
2044 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2046 * Fixed buffer overflow from Irssi SILC Client. Affected
2047 file irssi/src/fe-common/core/themes.c.
2049 * Fixed double free in client library in the file
2050 lib/silcclient/client.c when disconnecting from server.
2052 * Applied double free patch from cras to Irssi SILC client.
2053 Affected files irssi/src/core/[modules/expandos].c
2055 * Fixed the disconnection handling to Irssi SILC Client.
2056 The application must call silc_client_close_connection
2057 in ops->connect client operation in case of failure of
2058 the connection. Affected file is
2059 irssi/src/silc/core/client_ops.c.
2061 * Do not set sock->protocol to NULL in the function
2062 silc_client_close_connection after executing the protocol's
2063 final callback since the sock might not be valid anymore.
2064 Affected file lib/silcclient/client.c.
2066 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2068 * Do not enable SILC_THREADS if the linking with libpthread
2069 did not happen. Affected file configure.in.pre.
2071 * Added notion to protocol specification that server must
2072 verify the sent authentication payload with CMODE when
2073 setting the channel founder key. Implemented it to the
2074 server. Affected file silcd/command.c.
2076 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Added _EXTRA_DIST SILC distribution variable to the
2079 distributions file. It is used to conditionally add extra
2080 files or directories to the specific distribution. Affected
2081 files ./prepare, Makefile.am.pre and distributions.
2083 Removed the `_' from the start of the distribution names.
2086 * Added README.WIN32 for instructions to compile the Toolkit
2089 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Fixed a double free in disconnection in the server. Affected
2092 file is silcd/server.c.
2094 * Fixed the lib/silcske/groups.c to work now also with GMP
2095 MP library. The string conversion did not work when using
2096 specific base and the base is indicated in the string as well.
2098 * Created win32/ directory which now includes MSVC++ specific
2099 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2100 It will appear only in the toolkit distribution
2102 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Changed the key material distribution function in case when
2105 the hash output is too short. The data is now concatenated
2106 a bit differently than it used to. Made the change to the
2107 SKE protocol specification.
2109 * Added better GMP detection to configure.in.pre. A patch
2112 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2114 * Fixed a minor bug in SKE that might cause some problem on
2115 some platforms. Affected file lib/silcske/silcske.c.
2117 * Added the cookie checking for initiator in the SKE. It checks
2118 that the responder returns the sent cookie unmodified. The
2119 affected file is lib/silcske/silcske.c. Added new SKE
2120 error type INVALID_COOKIE that can be sent during the
2121 negotiation. Fixed some memory leaks as well.
2123 * Added the "invalid cookie" error message to Irssi SILC client's
2126 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Added `task_max' field to the SilcClientParams to indicate
2129 the maximum tasks the scheduler can handle. If set to zero,
2130 default values are used. Affected file lib/silcclient/silcapi.h.
2132 * Fixed memory leaks in silc_client_close_connection. Affected
2133 file lib/silcclient/client.c.
2135 * Added silc_client_del_client_entry to client library to free
2136 all memory of given client entry. Affected file is
2137 lib/silcclient/idlist.[ch].
2139 * Added new functions silc_client_del_channel and
2140 silc_client_del_server to delete channel and server entries.
2141 Affected file lib/silcclient/[silcapi.h/idlist.c].
2143 * Removed silc_client_del_client_by_id from silcapi.h.
2145 * Fixed the INFO command to return the server's own info
2146 correctly when querying by Server ID. Affected file is
2149 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2151 * Removed the non-blocking settings in WIN32 code in the
2152 silc_sock_[read/write] and added SleepEx instead. Affected
2153 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2154 of input data is now checked with FIONREAD and ioctlsocket.
2156 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Call silc_schedule_task_del_by_context in the
2159 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2160 Affected file lib/silccore/silcprotocol.c.
2162 * Call silc_protocol_cancel for active protocols in the
2163 silc_server_close_connection if the funtion
2164 silc_server_free_sock_user_data has not been called.
2165 Affected file silcd/server.c.
2167 * Generic tasks cannot be deleted using the del_by_fd
2168 task deleting function since generic tasks does not match
2169 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2171 * Added a notion to SILCOPER help file that the SILCOPER works
2172 only on router server, not on normal server.
2174 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Added for WIN32 support for the new scheduler as well.
2177 Affected file lib/silcutil/win32/silcwin32schedule.c.
2179 * Fixed the SHA1 implementation to work on various platforms.
2181 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2184 API. It is part of the scheduler now. Everything else is
2185 as previously but some functions has changed their names.
2186 Checkout the lib/silcutil/silcschedule.h for the interface.
2187 Updated all applications to use the new interface. Affected
2188 files are lib/silcutil/silcschedule.[ch].
2190 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Found a bug in the SKE implementation. The HASH value,
2193 specified by the protocol, was not computed correctly. The
2194 public key of the responder was not added to the computation
2195 even though it is mandatory. Affected file lib/silcske/silcske.c.
2196 This unfortunately causes incompatibilities with older
2197 clients and servers.
2199 * Added WIN32 specific network init and uninit functions:
2200 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2201 the Winsock2. Affected file lib/silcutil/silcnet.h and
2202 lib/silcutil/win32/silcwin32net.c.
2204 * Set the socket always to nonblocking mode on WIN32 after
2205 reading data or writing data. Affected file is
2206 lib/silcutil/win32/silcwin32sockconn.c.
2208 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2210 * Fixed various compilation problems under WIN32. Affected
2211 files lib/silcutil/win32/silcwin32thread.c and
2212 lib/silcutil/win32/silcwin32schedule.c.
2214 * Removed all _internal.h #includes from public header
2215 files. Internal headers must never be included from
2218 Removed also the lib/silcske/payload_internal.h file.
2220 * All include files that may be needed (public and some others
2221 included by the public headers) by application developers are
2222 now copied to the ./includes directory. It does not copy any
2223 internal headers. Affected file Makefile.defines.pre and all
2224 Makefile.am's under lib/ and subdirs.
2226 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2228 * Do not change the ~/.silc directory's permissions automatically.
2229 Affected file irssi/src/silc/core/clientutil.c.
2231 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Do not cancel the protocol in silc_server_close_connection
2234 it might cause recursion. Now cancelled in the function
2235 silc_server_free_sock_user_data. Affected file silcd/server.c.
2237 * Fixed the silc_server_remove_clients_by_server to regenerate
2238 the channel keys correctly finally. Added also new function
2239 silc_server_remove_clients_channels to actually do it.
2240 Affected file silcd/server.c.
2242 * Fixed the silc_server_new_channel to not crash by giving
2243 wrong router to the new channel. Affected file is
2244 silcd/packet_receive.c.
2246 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2249 which is given as argument to the silc_client_alloc now.
2250 It can be used to configure the client and set various parameters
2251 that affect the function of the client.
2253 * The USERS command in server did not check whether the channel
2254 is private or secret. Affected file silcd/command.c.
2256 * Added new argument to the USERS command in protocol specification.
2257 The USERS command now can take the channel name as argument
2258 as well. Added support for this in client and server and
2259 updated the protocol specs.
2261 * Completed the GETKEY command in client. It can be now used
2262 to fetch also servers public key not only some clients.
2263 Affected files lib/silcclient/command[_reply].c.
2265 * Added silc_client_get_server to return server entry by the
2266 server name. Affected files lib/silcclient/silcapi.h and
2269 * Redefined the IDENTIFY command in protocol specification to be
2270 more generic. It now can be used to query information about
2271 any entity in the SILC Network, including clients, servers and
2272 channels. The query may be based either the entity's name
2273 or the ID. Added support for this in both client and server.
2275 Affected files silcd/command.c and lib/silcclient/command.c
2276 and command_reply.c.
2278 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2279 the _from_client and _from_server functions. Affected file
2282 * Added silc_client_get_channel_by_id_resolve to the file
2283 lib/silcclient/silcapi.h to resolve channel information by
2284 its ID. Added also silc_client_get_channel_by_id that
2285 does not resolve it from the server.
2287 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2289 * Added SilcServerEntry context into the client library
2290 to represent one server. The INFO command now allocates
2291 these to save the resolved server info. For now on the
2292 client library will also keep information about servers,
2293 connected and resolved with INFO.
2295 The INFO command now allocates the SilcServerEntry context
2296 and saves the server info there. The COMMAND_REPLY in
2297 the INFO now returns the parameters to application in
2298 same order as defined in the protocol specification.
2300 The entries are cached in the client->server_cache.
2302 * The INFO command is now issued after received the Client ID
2303 from the server. Affected file lib/silcclient/client.c.
2305 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2306 to the application as the mode changer might be server.
2307 It is guaranteed that NULL is not returned anymore to the
2308 application. Affected file lib/silcclient/client_notify.c.
2310 The ID Type is now also passed to the application so that
2311 it can check whether the returned entry is SilcClientEntry
2314 Added new function silc_client_get_server_by_id to return
2315 the server entry by ID. Affected files are the
2316 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2318 * Do not create the channel in the Irssi SILC Client when issuing
2319 the JOIN command but when received the sucessful JOIN command
2320 reply. Otherwise the channel might get created even though we
2321 could not join it. The Affected file is
2322 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2324 * Fixed a channel joining bug in router. The router must also
2325 check the channel modes, invite and ban lists etc. when serving
2326 the JOIN command sent by normal server. Affected file is
2327 silcd/command.c. The router now resolves the client's
2328 information from the server who sent the JOIN command if it
2329 does not know it, and processes the JOIN command only after
2332 * Changed the SilcCommandCb to take new argument; void *context2.
2333 Affected file lib/silccore/silccommand.h
2335 The second argument in the command callbacks in the server now
2336 includes the SilcServerCommandReplyContext if the command was
2337 called as pending command callback from the command reply.
2338 Otherwise it is NULL. When called as pending the status of the
2339 command reply will be checked and if it was erronous the
2340 error will be sent to the original sender of the command.
2341 This way the client always receives the error messages even
2342 though the server was actually the one who received the error
2343 when it resent the command to router, for example. Affected
2344 files silcd/command[_reply].[ch].
2346 * Fixed sending WHOWAS command's error message to client if
2347 the requested client could not be found. It was missing.
2350 * Changed the CMODE and CUMODE commands reply arguments in the
2351 protocol specification. The Channel ID is now sent in both
2352 of the commands to identify the channel. Implemented this
2353 new feature to the client and server. Affected files
2354 lib/silcclient/command_reply.c and silcd/command.c.
2356 * Made better checks for invite and ban lists in the JOIN
2357 command in server. Affected file silcd/command.c.
2359 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2361 * The server now performs the incoming host IP/DNS lookup
2362 using the silc_socket_host_lookup and thus does not block
2363 the server anymore. Affected file silcd/server.c.
2365 * Completed the multi-thread support for SILC Scheduler in
2366 the lib/silcutil/silcschedule.c.
2368 * Fixed the configure.in.pre to detect the pthread correctly
2371 * Fixed a deadlock in silc_task_queue_wakeup in the file
2372 lib/silcutil/silctask.c.
2374 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Added new function silc_schedule_wakeup that is used in
2377 multi-threaded environment to wakeup the main thread's
2378 schduler. It needs to be used when a thread adds a new task
2379 or removes a task from task queues. After waking up, the
2380 scheduler will detect the task queue changes. If threads
2381 support is not compiled in this function has no effect.
2382 Implemented the wakeup mechanism to both Unix and WIN32
2383 systems. Affected files are lib/silcutil/silcschedule.[ch],
2384 lib/silcutil/unix/silcunixschedule.c and the
2385 lib/silcutil/win32/silcwin32schedule.c.
2387 * Added new function silc_task_queue_wakeup to wakeup the
2388 scheduler by the specified task queue. Affected file
2389 lib/silcutil/silctask.[ch].
2391 * The silc_socket_host_lookup_start now wakes up the scheduler
2392 after adding the timeout task. Affected file is
2393 lib/silcutil/silcsockconn.c.
2395 * The silc_socket_host_lookup is synchronous now if the threads
2396 support is not compiled in. However, the callback is still
2397 called asyncronously through the scheduler, anyway. Affected
2398 file lib/silcutil/silcsockconn.c.
2400 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Added new function silc_socket_host_lookup to perform
2403 asynchronous IP and FQDN lookups for the socket connection.
2404 Affected files lib/silcutil/silcsockconn.[ch].
2406 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2408 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2409 that may or may not compile the mutex support in.
2411 Changed the silc_mutex_alloc interface. It allocates the
2412 mutex now to the sent pointer and returns TRUE or FALSE.
2414 Affected file lib/silcutil/silcmutex.h.
2416 * Wrote the SILC Task Queue interface to support multi-threads.
2417 Affected file lib/silcutil/silctask.[ch].
2419 * Wrote the SILC Scheduler to support multi-threads. Affected
2420 file lib/silcutil/silcschedule.c.
2422 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2425 in lib/silcutil/win32/.
2427 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Defined SILC Mutex API and SILC Thread API and implemented
2430 them for Unix. Affected files are
2431 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2432 lib/silcutil/unix/silcunixmutex.c and
2433 lib/silcutil/unix/silcunixthread.c.
2435 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Fixed the silc_server_remove_clients_by_server's channel
2438 key re-generation. The hash table handling was incorrect
2439 and would not work with many channels. Affected file is
2442 * Fixed some memory leaks around the server code.
2444 * Rewrote the silc_server_get_users_on_channel to support IPv6
2445 based Client ID's. Affected file silcd/server.c.
2447 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2448 specification. However, a separate document must be written
2449 to define the detailed signing procedure and the payload
2450 associated with the flag. Defined the flag to the
2451 lib/silccore/silcchannel.h as well.
2453 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Changed the dynamic tables to static size tables in the
2456 lib/silccrypt/silchmac.c.
2458 * Removed GCC dependencies from the code. A patch by cras.
2460 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2462 * Do not show the error "Error receiving packet bla bla"
2463 in server if it really was not an error (-2 means that reading
2464 is pending). Affected file silcd/server.c.
2466 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Fixed a possible crash in silc_server_remove_clients_by_server
2469 in silcd/server.c. Fixed there also some memory leaks.
2471 * Fixed the silc_idlist_replace_client_id. It could replace
2472 wrong key in the hash table. Affected file silcd/idlist.c.
2474 * Do not check whether there are global users on the channel
2475 if the channel->global_users is FALSE. Affected functions
2476 silc_server_remove_from_one_channel and
2477 silc_server_remove_from_channels in silcd/server.c. Also,
2478 do not check if the removed client is local as we can be
2479 sure that global client was not removed from the channel
2480 and checking for global users is not needed.
2482 * The silc_server_remove_clients_by_server now re-generates
2483 the channel keys correctly for those channels that had
2484 clients removed from them. Affected file silcd/server.c.
2486 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2488 * Found the reason of random crashes in the server. We weren't
2489 ignoring the SIGPIPE signal (which can be sent in write())
2490 and it crashed the server. Affected file silcd/silcd.c.
2492 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * Assure that sock->user_data is not NULL in the function
2495 silc_server_packet_send in silcd/packet_send.c.
2497 * Disconnect the remote connection if it could not be added
2498 to any ID lists in the server. The affected file is
2501 * Check in silc_server_packet_send[_real/dest] that the
2502 socket is not disconnecting and ignore the data if it is.
2503 Affected file silcd/packet_send.c.
2505 * Define inline to __inline on native WIN32 compilation.
2506 Affected file includes/silcwin32.h.
2508 * Added some explicit type casts for inline code since MSVC
2509 require them. Affected files lib/silcutil/silcbuffer.h,
2510 lib/trq/silcdlist.h and lib/trq/silclist.h.
2512 * Print warning in log files from now on if the packet
2513 decryption fails. Affected file silcd/server.c.
2515 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Changed the `say' client operation's interface to accept
2518 new `type' argument to indicate the type of the message sent
2519 by the library. The application may filter the library's
2520 messages according the type. The affected file is the
2521 lib/silcclient/silcapi.h.
2523 * Added two new functions to lib/silcclient/silcapi.h:
2524 silc_client_del_client and silc_client_del_client_by_id.
2525 Affected file lib/silcclient/idlist.c.
2527 * Moved the clientincludes.h from includes/ to silc/ and
2528 serverincludes.h from includes/ to silcd/.
2530 * The modes for the CMODE and CUMODE are now passed as
2531 uint32 for application with COMMAND_REPLY. The affected
2532 file is lib/silcclient/command_reply.c.
2534 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * /WHOIS without arguments shows client's own information.
2537 Affected file lib/silcclient/command.c.
2539 * Changed PING to not accept any arguments. The specs
2540 says that client can ping only the connected server so
2541 requiring an argument is not needed. Affected file is
2542 lib/silcclient/command.c.
2544 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Fixed a fatal bug in private message sending and reception
2547 encryption and decryption when using private message keys.
2548 The implementation was incorrect and did not follow the
2549 specification. It causd that some of the message were
2550 lost since it did not use the sending and receiving keys
2551 as the protocol suggests. This has been fixed and will cause
2552 incompatibilities with older clients when sending private
2553 message encrypted with private message keys. Affected files
2554 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2555 and various other in Irssi SILC Client.
2557 Added `responder' boolean argument to the functions
2558 silc_client_add_private_message_key[_ske] to indicate when
2559 the key is added as responder or initiator of the key
2562 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Removed the silc_ske_check_version function and created
2565 a SilcSKECheckVersion callback. Added also a function
2566 silc_ske_set_callbacks that is now used to set all SKE
2567 callbacks. The callback functions are not given to
2568 the SKE functions anymore, but this function is used to
2571 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2573 * Added `silc_version' argument to the silc_client_alloc
2574 to define the version of the application for the library.
2575 The library will use the version string to compare it
2576 against the remote host's (usually a server) version
2577 string. Affected file lib/silcclient/silcapi.h
2579 * Added the KE protocol context to Key Agreement context
2580 in client library so that we can abort the SKE if it
2581 is in process when we get timeout. Affected file is
2582 lib/silcclient/client_keyagr.c.
2584 * Do not resolve the client ID forever if it returns in the
2585 first time that such client does not exist. This was done
2586 for example with private message. Affected file is
2587 lib/silcclient/client_prvmsg.c.
2589 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2591 * Do not add regex.h for WIN32. The affected file
2592 includes/silcincludes.h.
2594 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2595 not work yet 100%. It generates the DLL's automatically
2596 when compiling with --with-win32 under cygwin.
2598 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2600 * lib/contrib/regex.c is not compiled on WIN32.
2602 * Added silc_net_get_socket_opt function to the
2603 lib/silcutil/silcnet.h.
2605 * Added includes/silcwin32.h for WIN32 specific includes
2608 * Do not use ptime structure or any of the posix process
2609 functions on WIN32 in lib/silccrypt/silrng.c.
2611 * Added silc_gettimeofday to provide generic function
2612 for struct timeval on all platforms. Added the function
2613 to lib/silcutil/silcutil.h.
2615 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2618 library as they clearly belong there. As a plus side we
2619 can make the actual socket connection routines platform
2622 Added also new generic function silc_socket_read and
2623 silc_socket_write (that used to be silc_packet_[read/write].
2624 The implementation of these are platform specific.
2626 * Added WIN32 specific routines of silc_socket_[read/write]
2627 to lib/silcutil/win32/silcwin32sockconn.c.
2629 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2631 * Added preliminary support for native WIN32 compilation under
2632 cygwin (using the -mno-cygwin option for GCC) to the
2633 ./configure.in.pre. The --with-win32 now prepares the
2634 compilation for native WIN32.
2636 * Rewrote the SILC Scheduler interface in the file
2637 lib/silcutil/silcschedule.h. The scheduler is now context
2638 based and does not have anymore any global static scheduler.
2639 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2640 and created lib/silcutil/win32 directory for WIN32 based
2643 * Added Unix specific network routines to the
2644 lib/silcutil/unix/silcunixnet.c and the old
2645 lib/silcutil/silcnet.c includes now only generic routines.
2647 Added WIN32 specific network routines to the
2648 lib/silcutil/win32/silcwin32net.c.
2650 * Added Unix specific utility functions from the
2651 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2653 * Added WIN32 SILC Scheduler to the file
2654 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2657 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Do not handle JOIN notify in the server if the target client
2660 is not registered (idata->registered == FALSE). The affected
2661 file is silcd/packet_receive.c.
2663 * Update the nickrec->founder in event_cumode in the Irssi SILC
2664 client. Affected file irssi/src/silc/core/silc-channels.c.
2666 * Fixed the CUMODE_CHANGE notify handling in the server when
2667 server and router are announcing their clients on channels.
2668 Now the mode changes are saved and notified correctly. The
2669 affected file is /silcd/packet_receive.c.
2671 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2672 They really did not replace the cache entry in the ID Cache.
2673 Now they do that. Affected file silcd/idlist.c.
2675 * Fixed the KICK notify handling in the Irssi SILC client to
2676 update the channel records so that the kicked client does not
2677 appear to be on the channel. The affected file is
2678 irssi/src/silc/core/silc-channels.c.
2680 * Always update the conn->current_channel when executing command
2681 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2683 * Fixed the KILL notify handling in Irssi SILC client to remove
2684 the killed client on all channels.
2686 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Fixed the silc_parse_command_line to remove extra spaces
2689 from the start and end of the arguments. Affected file is
2690 lib/silcutil/silcutil.c.
2692 * Cancel and free any active protocol in the function
2693 silc_server_close_connection. Affected file silcd/server.c.
2695 * Cancel and free any active protocol in the function
2696 silc_client_close_connction. Affected file is
2697 lib/silcclient/client.c.
2699 * Do not execute the KILL command for clients that are in
2700 history (ie. they are not in the network). Affected file is
2703 * Fixed KILL notify handling, client does not crash anymore.
2704 Affected file irssi/src/silc/core/silc-channels.c.
2706 * Reduced the default packet buffer size from 2048 to 1024 in
2707 lib/silccore/silcpacket.c.
2709 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2710 counter to the SKE context that is incresed when the SKE library
2711 performs async operation outside the library. If the outside
2712 process frees the SKE context and FREED status will be set
2713 and the library will detect after the sync operation that the
2714 libary is freed. The affected files are
2715 lib/silcske/silcske[_status].[ch].
2717 * Resolve the client entry information in the function
2718 silc_client_channel_message to assure that NULL pointer is not
2719 passed as client entry to the application. */
2721 * Fixed the task timeout calculation to assure that there is
2722 never negative timeouts. The affected file is
2723 lib/silcutil/silcschedule.c.
2725 * Fixed the channel user mode notification sending in server.
2726 It was sent point-to-point to the router (or to server by router)
2727 but it needs to be destined to a channel. The routines now
2728 supports sending the channel user mode notifys to the channels
2729 when announcing clients and channels. Affected files are
2730 silcd/server.c and silcd/packet_receive.c.
2732 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2733 It did not actually replace the old channel entry in the cache.
2734 Affected file lib/silcclient/client_notify.c.
2736 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2738 * Fixed a possible crash in silc_packet_send_prepare. It now
2739 assures always that there is enough space in the buffer and
2740 at the tail area of the buffer (for MAC).
2742 Fixed the inbound buffer reallocation in silc_packet_read.
2743 It was old code and did not handle the reallocation correctly.
2746 The affected file is lib/silccore/silcpacket.c.
2748 * Fixed buffer overflow in silc_parse_nickname in the file
2749 lib/silcutil/silcutil.c.
2751 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * make install generates new server keys only if there is not
2756 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2758 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2759 Added check that if the NOREPLY is set then we will not send
2760 the away message. This avoids infinite loop of away messages
2761 if both clients are away. The affected file is
2762 lib/silcclient/client_prvmsg.c.
2764 * Fixed client crash if /NICK was given without arguments.
2765 Affected file lib/silcclient/command.c.
2767 * Server does not send the invite list in INVITE command back
2768 to the client if the list was not altered. Added this notion
2769 to the protocol spec as well. Affected file silcd/command.c.
2771 Fixed possible crash in INVITE command by checking the
2772 value of silc_server_get_client_route command.
2774 * Fixed the INVITE notify type handling. The arguments are now
2775 taken in correct order and client does not crash. The affected
2776 file is irssi/src/silc/core/silc-channels.c.
2778 Removed the "Inviting xxx to channel" message from the
2779 client library away and let the application handle it.
2780 Affected file lib/silcclient/command.c. Added that message
2781 to Irssi SILC client's message formats.
2783 * Fixed CMODE command crash in client. It now checks the
2784 amount of arguments correctly and does not crash. The affected
2785 file is lib/silcclient/command.c.
2787 * Do not create new channel automatically in silc_channels_join
2788 but check whether the channel by that name already exists.
2789 Affected file irssi/silc/core/silc-channels.c.
2791 * Do not send the SERVER_SIGNOFF to router if the disconnected
2792 entity was the router. Affected file silcd/server.c.
2794 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2795 SILC client as it was missing from there.
2797 Added the handling of the KICK notify to the Irssi SILC client
2798 as it was missing. Added "you have been kicked" message to
2799 Irssi SILC client's message modules formats.
2801 Added the handing of the KILL notify to the Irssi SILC client
2802 as it was missing. Added the kill message module formats
2805 The affected file is irssi/src/silc/core/silc-channels.c.
2807 * The router did not save the channel mode the server announced.
2808 Affected file silcd/packet_receive.c.
2810 * Fixed a possible crash in INFO command in server. If the
2811 server did not provide the server info it crashed. Affected
2812 file silcd/command.c.
2814 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Fixed the GETKEY command in the server to check also the
2817 global list. Otherwise the GETKEY would not work correctly
2818 in normal SILC server. Affected file silcd/command.c.
2820 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Fixed GETKEY crash, it crashed if the command did not succseed.
2824 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2827 is now real and not just an macro interface to GMP.
2829 Removed the entire GMP from the source tree and imported new
2830 NSS MPI library instead. Reason for removing GMP is that it is
2831 extremely large and compiles extremely slow. The NSS MPI
2832 is only a few files and compiles in less than 10 seconds.
2833 The speed is also about the same as GMP. The MPI is imported
2834 to lib/silcmath/mpi.
2836 If the system has GMP installed we will still use the GMP.
2837 If it is not then the NSS MPI will be compiled.
2839 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * Merged a long nickname (127 characters long) crash bugfix from
2842 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2844 * Merged a freed memory reference bugfix from Irssi CVS tree.
2845 Affected file irssi/src/core/commands.c.
2847 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2849 * Added the server's public key sving and verification to the
2850 server when performing the SKE. This was missing and the
2851 remote server's (or router's) public key was accepted without
2852 checking whether we have it previously or trust it at all.
2853 Affected file silcd/protocol.c.
2855 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Check in the silc_server_timeout_remote if protocol is active
2858 and make sure that the protocol's final callback is called so
2859 that all memory if freed. Affected file silcd/server.c.
2861 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2863 * silc_server_whois_send_reply crashed the server if the nickname
2864 was 127 characters long. Affected file silcd/command.c.
2866 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Added sanity check to the silc_server_new_client. If the hostname
2869 is provided inside username then check that the provided hostname
2870 really is the same as the resolved one. If the hostname was not
2871 resolved then check it from the public key. Affected file is
2872 silcd/packet_receive.c.
2874 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2875 if the server disconnected us and the connection is not valid
2876 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2878 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2879 the library to the lib/silcutil/silcutil.[ch].
2881 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Close log file after open. Affected file
2884 lib/silcutil/silclog.c.
2886 * Check whether sock == NULL in silc_client_send_packet and return
2887 if it is. Affected file lib/silcclient/silcclient.c.
2889 * Check rec->entry == NULL in the Irssi SILC Client before
2890 sending the channel message. Affecte file is
2891 irssi/src/silc/core/silc-servers.c.
2893 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2895 * Merged a splitted window bugfix from Irssi CVS tree. The
2896 affected file is irssi/src/fe-text/textbuffer-view.c.
2898 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2899 It did not print nickname.
2901 * Improved the distributions system a bit.
2903 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2906 irssi/src/fe-text/gui-window.c.
2908 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2909 to in-active server. The affected file is
2910 irssi/src/silc/core/client_ops.c.
2912 * Resolve the client in USERS command reply if the entry does
2913 not have username resolved. The affected file is
2914 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2915 command to WHOIS command to really resolve stuff. The USERS
2916 is not used any more in any critical section so WHOIS can
2917 be used even though it might be slower than IDENTIFY.
2919 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2922 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Changed the protocol API a bit more consistent in the
2925 lib/silccore/silcprotocol.[ch].
2927 * Changed the following headers to ROBODoc format:
2929 lib/silccore/silcpayload.h
2930 lib/silccore/silcprotocol.h
2931 lib/silccore/silcsockconn.h
2933 All core library headers are now formatted.
2935 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Fixed a bug in Irssi SILC client; do not show that you are
2938 server/router operator if you really are not. Affected file is
2939 irssi/src/silc/core/client_ops.c.
2941 * Renamed silc_command_free_payload to silc_command_payload_free.
2942 Affected file lib/silccore/silccommand.h
2944 * Added silcmath.h to include the prototoypes of various routines
2945 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2948 * Changed the following headers to ROBODoc format:
2950 lib/silccore/silcchannel.h
2951 lib/silccore/silccommand.h
2952 lib/silccore/silcid.h
2953 lib/silccore/silcidcache.h
2954 lib/silccore/silcmode.h
2955 lib/silccore/silcnotify.h
2956 lib/silccore/silcpacket.h
2957 lib/silcmath/silcmath.h
2959 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2961 * Added checking to the server code not to start the server if
2962 ciphers and stuff are not configured properly. Affected files
2963 silcd/serverconfig.[h] and silcd/server.c.
2965 * Changed the layout of the header files of the public interfaces
2966 in the SILC libraries. The new layout supports ROBODoc
2967 documentation tool (and some others) so that it is easy to create
2968 a library reference manual. All the other headers and source
2969 code must still follow the CodingStyle document. Also source
2970 code must not include these ROBODoc stuffs, only the headers.
2971 Furthermore, all public interface headers must now be named
2972 by using `silc' prefix, example: silcapi.h, silccipher.h.
2973 Some files were renamed due to this. All the other headers
2974 must not be used as public interfaces. I will update the
2975 CodingStyle document later. Changed following headers, so far:
2977 lib/silcclient/silcapi.h
2978 lib/silccore/silcauth.h
2979 lib/silccore/silcprivate.h
2980 lib/silccrypt/silcdh.h
2982 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2986 * Removed silc_client_packet_send_flush from the client library
2987 as it is not needed. Affected file lib/silcclient/client.[ch].
2989 * Added printing of message of unresolved authentication method
2990 to the Irssi SILC client. Added it to the module formats.
2991 Removed the same message from the client library.
2993 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2995 * Added new distribution feature, DISTLABEL. Every distribution
2996 can define own preprocessor label that can be used in the
2997 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2998 file distributions, acconfig.h.pre and prepare.
3000 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3002 * Added Makefile.defines_int to include the actual definitions
3003 for Makefile.defines.in. Tested the new distribution system,
3004 created distributions and tested installation.
3006 * Added AWAY message printing to the Irssi SILC client. Added
3007 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3009 * Added SCONNECT command to call the SILC's CONNECT command.
3010 Cannot use CONNECT directly since Irssi uses that internally.
3011 Affected file irssi/src/silc/core/silc-servers.c.
3013 Added ACTION local command. It is same as ME command but takes
3014 the channel as mandatory argument.
3016 Rewrote some of the Irssi's help files to suite for SILC
3019 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * Added Makefile.defines[.in] that should for now on be included
3022 in all Makefile.am file in the source tree. That file includes
3023 all common compilation definitions for SILC source tree.
3025 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Minor changes to the ./prepare script to change the package
3028 name according the distribution name to the configure.in.
3030 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Created new distribution system. Added file `distributions'
3033 that defines all the distributions that can be created out of
3034 the SILC source tree. The ./prepare script now reads that
3035 file to determine how to prepare the distributions. The
3036 first argument to the ./prepare is the name of the distribution
3037 and second is the version of the distribution. If given
3038 without arguments it creates the default (toolkit) distribution
3039 with the default version (defined in ./prepare).
3041 All Makefile.am files that are subject to the distributions
3042 are now named as Makefile.am.pre. These are ./Makefile.am
3043 and lib/Makefile.am. Others may be changed later.
3045 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Added invite list, ban list, some key management and connection
3048 error message printing to module formats in the Irssi SILC client.
3050 * Added new silc_client_set_away_message to set the away message
3051 that is back to the person who sent private message. The
3052 affected file lib/silcclient/silcapi.h and the
3053 lib/silcclient/client_prvmsg.c.
3055 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Fixed the private message sending in the Irssi SILC client,
3058 added local command KEY to the Irssi SILC client.
3060 Added key management and key agreement message formats to the
3061 irssi/src/fe-common/silc/module-formats.[ch].
3063 Added USERS (alias WHO) printing, server/router operator
3064 indication and LIST command printing to the module formats.
3066 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3068 * Fixed channel joining notify handling, cumode notify handling
3069 from Irssi SILC client.
3071 * Added SILC specific module-formats to the Irssi SILC client so
3072 that SILC specific message hilighting, colors etc is possible.
3073 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3075 Added channel mode, channel user mode, actions, notices,
3076 whois and whowas printing to the the module-formats.c.
3078 * Fixed a bug in channel deletion in the server. The channel
3079 is not left to the cache even if the channel founder auth mode
3080 is set when there are no users anymore on the channel. Affected
3081 file silcd/server.c.
3083 * The silc_net_localhost now resolves the entire hostname including
3084 the domain name. Affected file lib/silcutil/silcnet.c.
3086 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Changed the ask_passphrase client operation to be ascynchronous.
3089 It has now a completion callback and a context that the
3090 application must call after it has got the passphrase from
3091 the user. Affected files lib/silcclient/silcapi.h,
3092 lib/silcclient/protocol.c, lib/silcclient/command.c and
3095 Added SilcAskPassphrase callback that the application calls
3096 to deliver the passphrase to the library.
3098 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3099 The public key verification and especially a certificate
3100 verification is asynchronous procedure.
3102 Added new SILC_SKE_STATUS_PENDING status to indicate the
3103 request is pending and a callback will be called to finalize
3106 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3107 indicate that remote end did not send its public key (or
3108 certificate), even though we require it. Added check for this
3109 condition in the SKE. This was a security bug, now fixed.
3111 Defined new SilcSKEVerifyCbCompletion callback that is called
3112 when the verification process is completed.
3114 The affected files lib/silcske/silcske_status.h and
3115 lib/silcske/silcske.[ch].
3117 * Changed the verify_public_key client operation to be async
3118 as well. Defined SilcVerifyPublicKey callback that is used to
3119 indicate the success of the public key verification process.
3121 Changed the server and client to use the new async client
3124 * Changed the Irssi SILC client's internal scheduler to be called
3125 twice as many times as it used to be. As a result the client
3126 should be a bit faster now. Affected file is
3127 irssi/src/silc/core/silc-core.c.
3129 * Added support to Irssi SILC client of asynchronous public key
3130 verification and passphrase inquiry. Affected file is
3131 irssi/src/silc/core/silc-core.c.
3133 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Do not say "You have left channel %s" in client library.
3136 Moved it to the application. Affected files are
3137 lib/silcclient/command.c and silc/client_ops.c.
3139 * Fixed silc_client_get_clients. Command context was not
3140 duplicated and was freed memory in the callback. Affected
3141 file lib/silcclient/idlist.c.
3143 * Do not say "you are now talking..." on JOIN command in the
3144 client library. The appliation must handle it.
3146 * Do not say ".. changed topic to" in command reply in the
3147 client libary. The application must handle it.
3149 * Fixed TOPIC command sending in the client library.
3151 * Fixed a memory leak in silc_client_command_free in the file
3152 lib/silcclient/command.c.
3154 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Imported a modified version of Irssi client to the source tree.
3157 The Irssi will be used to create a new client called
3158 Irssi SILC. Imported to irssi/.
3160 Added silc_core_init_finish function to the Irssi. Affected
3161 file irssi/configure.in.
3163 A lot changes in the Makefile.ams around the irssi tree.
3165 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Do not rehash if the new size is same as the old size of the
3168 hash table, in the silc_hash_table_rehash*. The affected file
3169 lib/silcutil/silchashtable.c.
3171 * Replaced hash_table_del_by_context calls from the server
3172 (when channel->user_list and client->channels) to the
3173 hash_table_del as it is sufficient and faster.
3175 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3177 * Added silc_hash_table_list, silc_hash_table_get and the
3178 SilcHashTableList structure to provide an alternative way to
3179 traverse the hash table. The affected files are
3180 lib/silcutil/silchashtable.[ch].
3182 * Changed the server's idlist routines to use the hash table
3183 routines to optimize the code.
3185 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Replaced the client entry's `channel' list and channel entry's
3188 `user_list' list to hash tables for optimized lookup. Changed
3189 the code to use the hash table interface around the code.
3190 Affected file lib/silcd/idlist.[ch].
3192 * Added `auto_rehash' boolean argument to the function
3193 silc_hash_table_alloc to indicate whether the hash table should
3194 auto-rehash when it thinks is appropriate time. It will
3195 increase the hash table size if the there is twice as much
3196 entries in the table than the size of the table, and will
3197 decrease the size if there are twice as less entries than
3198 the size of the table.
3200 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3204 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * silc_idcache_purge_by_context deletes the entry now by context
3207 as it is supposed to do. Affected file lib/silccore/idcache.c.
3209 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3210 client is not anymore valid (WHOWAS givens the info) and not
3211 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3213 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Removed the `data' and `data_len' arguments from the ID Cache
3216 interfaces and added `name' argument. ID Cache does not handle
3217 anymore the binary data only a names associated with given ID.
3219 * When hashing a Client ID with silc_hash_id the entire ID is
3220 not hashed anymore, instead only the hash of the Client ID is
3221 hashed. This way we can access the Client ID from the cache
3222 with Client ID but with the hash of the ID (which is a hash of
3223 the nickname) as well without any difference in performance.
3225 Added also silc_idcache_find_by_id_one_ext to do one on one
3226 searching when we have the actual ID. Added also function
3227 silc_hash_client_id_compare. The affected files are
3228 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3230 * When hashing the name associated with a ID it is always done
3231 in lowercase. This way we can access the cache without worrying
3232 about case-sensitivity, even though, for example nicknames are
3235 * Fixed a bug in server with channel message sending. It put
3236 wrong ID type as destination ID. The affected file
3237 silcd/packet_send.c.
3239 * silc_idcache_del_by_context now deletes from all hash tables
3240 by context. Affected file lib/silccore/idcache.c.
3242 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Changed the client library to use the new ID Cache interface.
3245 Changes around the source tree.
3247 * Added silc_hash_table_rehash_ext to rehash with specific
3248 hash function. Affected file lib/silcutil/silchashtable.[ch].
3250 * Added silc_hash_string_compare to compare two strings in the
3251 hash table. Affected file lib/silcutil/silcutil.[ch].
3253 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Added new function silc_idcache_del_by_context into the
3256 lib/silccore/idcache.[ch].
3258 * Changed the server's ID list routines to use the new ID Cache
3259 interface. Changes around the source tree.
3261 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added silc_hash_table_del[_by_context]_ext functions in to the
3264 lib/silcutil/silchashtable.[ch].
3266 Removed silc_hash_table_find_all* routines and added new
3267 silc_hash_table_find_foreach to replace them.
3269 Added silc_hash_table_replace_ext function as extended
3270 replacing function. Separated the simple hash table interface
3271 from the extended hash table interface in the file
3272 lib/silcutil/silchashtable.h.
3274 * Fixed minor bugs and changed it to use some of the new
3275 hash table functions in lib/silccore/idcache.c
3277 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Added new function silc_hash_table_find_all to return all keys
3280 in the hash table by the specified key. As the hash table is
3281 collision resistant it also makes it possible to have several
3282 duplicate keys in the hash table. This function may be used to
3283 find all of the keys from the hash.
3285 Added user_context arguments to the SilcHashFunction,
3286 SilcHashCompare and SilcHashDestructor to deliver user specified
3289 Added new fuctions silc_hash_table_find[_all]_ext to do
3290 extended lookup with specified hash and compare functions and
3291 specified user contexts.
3293 Added new function silc_hash_table_add_ext to add the key
3294 with specified hash function and user context.
3296 Added new function silc_hash_table_foreach to traverse all
3297 entrys in the hash table. Added SilcHashForeach callback
3300 Added new function silc_hash_table_del_by_context to delete
3301 the entry only if the context associated with the key matches.
3303 Affected files are lib/silcutil/silchashtable.[ch].
3305 * Removed silc_hash_[server/client/channel]_id and added just
3306 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3307 silc_hash_id_compare to compare two ID's using as the hash table
3308 comparison function. Added also silc_hash_data to hash
3309 binary data and silc_hash_data_compare to compare it.
3311 * Removed silc_idlist_find_client_by_hash as it is not needed
3312 anymore. Affected file silcd/idlist.[ch].
3314 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3315 to use internally the SilcHashTable. The new ID Cache is a lot
3316 faster than the old one. Some of the ID Cache interface was also
3317 rewritten and obsolete and stupid functions were removed.
3319 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3321 * Added entry_count field to the SilcHashTable to keep the number
3322 of the entries in the table. Implemented the function
3323 silc_hash_table_rehash. Added new function
3324 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3326 Fixed a minor bug in silc_hash_table_free.
3328 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3329 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3330 into the lib/silcutil/silcutil.[ch].
3332 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3334 * Implemented a collision resistant hash table into the
3335 lib/silcutil/silchashtable[ch]. See the header and the source
3336 for the SilcHashTable API.
3338 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Merged dotconf version 1.0.2 into lib/dotconf.
3342 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3344 * Do not compile anything in lib/silcsim/* if the SIM support
3345 is not enabled. The tree should now compile without problems
3348 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Compiled the SILC under cygwin. Compiled and tested briefly
3351 without problems. More tests needed. The SIMs didn't compile
3354 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3356 * Fixed possible crash in silc_get_username in the
3357 lib/silcutil/silcutil.c.
3359 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3361 * Fixed a va_arg in silc/client_ops.c.
3363 * Oops, RC5 routines were named AES and caused some problems
3364 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3366 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Added new SilcIDIP structure into the lib/silccore/id.h and
3369 replaced the old `ip' fields from all SILC ID's to that type.
3370 This is a step towards IPv6 support.
3372 The silc_id_get_len takes now the ID as an extra argument.
3373 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3374 both IPv4 and IPv6 based ID's.
3376 The affected files are lib/silccore/id.[ch] and other files
3377 around the tree using these routines.
3379 * Removed the ID length arguments in server from various
3380 silc_server_send_notify_* routines -> they are not needed
3383 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * Fixed memory leak in silc_encode_pem_file in the file
3386 lib/silcutil/silcutil.c.
3388 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Check minor version as well in the SKE. Affected files are
3391 silcd/protocol.c and lib/silcclient/protocol.c.
3393 * Added --identifier option to the server so that an identifier
3394 can be when creating the public key for the server. Affected
3395 file is silcd/silcd.c.
3397 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3398 lib/silccrypt/silcpkcs.c.
3400 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * Register default ciphers and stuff when using -C option with
3403 the server. Affected file sildc/silcd.c.
3405 * Put back the servers public key filename format, it is better
3406 than the new one. For now, the client keys are saved with the
3407 new filename format. The affected file silc/client_ops.c.
3409 * Implemented the Cipher API for the rest of the ciphers that
3410 did not implement it or implemented it the wrong way.
3412 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Register default ciphers and stuff when using the -S option
3415 in the client. Affected file silc/silc.c. Same also when
3416 creating new key pair with -C option.
3418 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3420 * Fixed the silc_verify_public_key client operation function to
3421 save the public keys differently. The fingerprint is now
3422 used as filename and not the hostname. This way also the
3423 client keys are saved uniquely and not with hostnames. The
3424 affected file is silc/client_ops.c.
3426 * Trimmed the silc_hash_fingerprint function to remove extra
3427 whitespaces from the end of the fingerprint. The affected
3428 file is lib/silccrypt/silchash.c.
3432 * Added silc_cipher_register_default function to register all
3433 default ciphers. It can be used when configuration files
3434 does not exist and the application does not want any specific
3435 ciphers in any specific order.
3437 The SilcDList is now used as silc_cipher_list dynamically
3438 allocated cipher list. Removed the static list all together
3439 and now all ciphers must be allocated to the dynamic list.
3440 The silc_cipher_alloc routine was changed to check only the
3443 All silc_cipher_* routines that used to return int returns
3446 The affected files lib/silccrypt/silccrypt.[ch].
3448 * The same thing was done to silc_hash_* as for silc_cipher_*
3449 routines. Affected files lib/silccrypt/silchash.[ch].
3451 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3452 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3453 Added also silc_pkcs_[un]register[_default] functions.
3454 Removed the data_context from the PKCS API.
3456 * Added silc_hmac_register_default function to register default
3457 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3458 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3459 to unregister all hmacs at once.
3461 * Register the default ciphers, hash functions, PKCSs and HMACs
3462 if client's configuration file does not exist. The affected
3465 * The client did not load the hash functions from the SIM
3466 modules at all. Added support for this. Affected file is
3467 silc/clientconfig.c.
3469 * When decoding public key with silc_pkcs_public_key_decode, check
3470 the supported algorithm only if PKCS are registered. Affected
3471 file lib/silccrypt/silcpkcs.c. The same was done with the
3472 silc_pkcs_private_key_decode.
3474 * Fixed the SILC List routines to keep the list always in order.
3475 It used to change the list's order when traversing the list but
3476 not it preserves the order. Affected file lib/trq/silclist.h.
3478 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3480 * Added the client library to use the SilcSocketConnection's
3481 reference counter (by silc_socket_dup) to prevent the bug that
3482 the socket object may be freed underneath async operation.
3484 * The name resolv library checking fixes in the configure.in.pre.
3487 * Created new version of the protocol drafts for future
3488 development. The -03 drafts are the ones that will be changed
3489 in the trunk now and the -02 will remain as they are.
3491 * Send list of CUMODE notifys to the router when announcing
3492 the channel users to the router. Affected file silcd/server.c.
3493 If the router receiving channel founder CUMODE for a channel
3494 that already has channel founder it will send CUMODE notify
3495 to the sender to remove the channel founder rights from the
3496 announced client. Affected file silcd/packet_receive.c.
3498 * The CUMODE notify may now use Server ID as well as the entity
3499 who changes the mode. Updated protocool specs.
3501 * Updated INSTALL and README files.
3503 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * New web pages in the http://silc.pspt.fi. The pages was
3510 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Implemented the [DenyConnectin] config section in the server.
3513 Added silc_server_config_denied_conn to check whether incoming
3514 connection is denied. Affected file silcd/serverconfig.[ch].
3516 * Do not check the ports when checking the incoming configuration
3517 data if the port is 0, meaning any. Affected file is
3518 silcd/serverconfig.c.
3520 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Fixed buffer overflow in silc_string_compare in the file
3523 lib/silcutil/silcutil.c.
3525 * Fixed double free in silc_server_command_leave in the file
3528 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Fixed the version checking in the server. Affected file is
3533 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Fixed the configuration data fetching when accepting new
3536 connections in the server. Affected file silcd/server.c.
3538 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Added `sender_entry' argument to the function
3541 silc_server_packet_relay_to_channel so that we can check
3542 whether some destination actually belongs to the same route
3543 the sender belongs (ie, we must not resend the packet to the
3544 sender). Affected file silcd/packet_send.[ch].
3546 * Added `servername' field to the SilcClientEntry in the server
3547 to hold the name of the server where client is from. Affected
3548 file is silcd/idlist.h.
3550 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Moved the channel message encrypting in the router betwen
3553 router connections from silc_server_channel_message to the
3554 silc_server_packet_relay_to_channel since we want to check
3555 whether we have anybody channel before encrypting anything.
3556 Affected files silcd/packet_[receive/send].c.
3558 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Fixed the [AdminConnection] server config section to support
3561 multiple entries. Affected file silcd/serverconfig.c.
3563 * Added support into the server to check the validity of the
3564 incoming connection before executing any KE or authentication
3567 * The connection configuration is now saved to the KE and
3568 connection auth protocol contexts and not fetched anymore in
3569 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3571 * The local hosts listenning address and port is also resolved
3572 now when starting the server. We want to have the socket object
3573 to include the real address and port for the listener. Added
3574 new function silc_net_check_local_by_sock into the files
3575 lib/silcutil/silcnet.[ch].
3577 * Fixed a broadcast bug in server -> do not broadcast if we
3580 * Fixed a routing bug. Do not route broadcast packets ever.
3581 Broadcast packets must be processed always and not routed since
3582 they may be destined to some other host than yourself and thus
3583 would get routed without no good reason. Affected file is
3586 * Added function silc_server_config_is_primary_route to check
3587 whether primary router connection has been configured (a router
3588 configuration that we are initiating). If there is not, we
3589 will assume that there is only two routers in the SILC network
3590 and we will use the incoming router connection as our primary
3591 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3593 * Changed the order of the broadcasting. Broadcast _after_ the
3594 packet has been processed not before. Affected file is
3597 * Fixed a [ClientConnection] parsing bug. The port was never
3598 parsed correctly thus resulting to port 0. Affected file
3599 silcd/serverconfig.c.
3601 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3602 argument and did not set the broadcast packet flag. Affected
3603 file silcd/packet_send.c. Fixed same bug in the function
3604 silc_server_send_notify as well.
3606 * If we receive NEW_ID packet for our own ID in the server, ignore
3609 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Removed the nickname from the Private Message Payload.
3614 Updated the code and the protocol specs.
3616 * Updated protocol specs for submitting to the IETF.
3618 * Tweaked the Random Number Generator a bit. Affected file
3619 lib/silccrypt/silcrng.c. Exported a new function
3620 silc_rng_[global]_add_noise which can be used to add more
3623 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Do not parse packets with different timeout when protocol
3626 is active -> may cause problem with rekey. Affected file
3629 * When server receives signoff notify it must not create
3630 new channel key if the client is on any channels since the
3631 sender of the signoff notify will create it.
3633 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Added printing of error messages during SKE protocol from the
3636 failure packet sent by server during SKE. Affected file
3639 * Removed the client's failure_callback handling with timeout
3640 and handle it immediately when received.
3642 * The SKE library returned wrong type in SUCCESS and FAILURE
3643 packets. They must be 32 bit MSB not 16 bit MSB.
3645 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Ok, rewrote the logic of the re-key and now it seems to work.
3648 I tested it on high traffic with frequent re-keys without
3649 problems. Added hmac_receive (and renamed hmac to hmac_send)
3650 in SilcClientConnection in lib/silcclient/client.h and
3651 in SilcIDListData in silcd/idlist.h. Also, removed the
3652 SilcPacketParserContext's cipher and hmac fields as they are
3653 not needed anymore and actually caused some problems when
3654 the ciphers and hmac's changed underneath the packet parser.
3656 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3658 * If re-key protocol is active then process the incoming packets
3659 synchronously since we must assure that icoming packets encrypted
3660 with the old key is processed before the new keys is set to
3661 use. This is true other packets than for REKEY packets.
3662 Affected file silcd/server.c. The same was done to client library
3663 as well, affected file lib/silcclient/client.c.
3665 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3667 * Fixed bug in client and server to accept the force send if
3668 the packet is send from silc_[server/client]_packet_process
3669 function. Otherwise the packets are never delivered, oops.
3671 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Disable force sending of packets when REKEY protocol is active.
3674 We must assure that no packet is sent directly when rekey is
3675 performed. All packets must be sent through packet queue.
3676 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3677 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3678 function is silc_[server/client]_packet_send_real to check
3681 * Replaced the SIM paths from example config files to
3682 /usr/local/modules. Also, make install creates now
3683 /usr/local/silc/logs directory to hold all the SILC server
3686 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Made the configure.in.pre work on Solaris. Patch by salo.
3690 * Made all ciphers compatible with non-x86 machines. Defined
3691 CBC mode macros into lib/silccrypt/ciphers_def.h.
3693 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Fixed the make install.
3697 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * When MAC computation fails the silc_packet_decrypt returned 0
3700 even though it was supposed to return -1. Fixed this. The
3701 affected file is lib/silccore/silcpacket.c.
3703 * Do not replace the config files in /etc/silc (in make install)
3704 if they already exist. Affected file ./Makefile.am.
3706 * Do not send re-key packets immediately but through packet queue.
3707 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3709 * Changed silc_net_check_host_by_sock to return FALSE if the
3710 IP/DNS could not be resolved. Though, it returns the IP address
3711 now even if it could not resolve it (but returns also FALSE).
3712 Affected file lib/silcutil/silcnet.[ch].
3714 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Added silc_pkcs_decode_identifier to decode the public key's
3717 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3718 Added also silc_pkcs_free_identifier. Added also new context
3719 SilcPublicKeyIdentifier.
3721 * Added -S option to the silc client. It is used to dump the
3722 contents of the specified public key file.
3724 * Changed the PKCS api to return the public key length when
3725 setting the public key.
3727 * Fixed a fatal bug in the public and private key file loading.
3728 Affected file lib/silccrypt/silcpkcs.c.
3730 * Execute the packet parsing for client with zero (0) timeout
3731 if the protocol is active. Affected file silcd/server.c.
3733 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Made the key generation options to the silcd program. Added
3736 -C option, equivalent to client's option.
3738 * Added new [ServerKeys] config section to the server. It
3739 configures the server's public and private key.
3741 * Defined generic Public Key Payload into the protocol
3742 specification to send specific type of public keys and
3745 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3746 public key or certificate.
3748 * Implemented the GETKEY command to the server and to the
3749 client library and on user interface.
3751 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3753 * Made preliminary `make install' work.
3755 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Added SilcServerRekey context into silcd/idlist.h.
3759 * Added the PFS support as defined in the specification to the
3760 SKE protocol. Affected files lib/silcske/*.c.
3762 * Added `ske_group' field to the SilcServerRekey context to hold
3763 the number of the SKE group that is used with PFS in re-key.
3764 Affected file silcd/idlist.h.
3766 * Added PFS re-key support to the server. Affected file is
3769 * Added silc_protocol_cancel to cancel execution of the next
3770 state of the protocol. Affected file is
3771 lib/silccore/silcprotocol.[ch].
3773 * Added the re-key support with and without PFS to the client
3774 library. Re-key is performed once in an hour, by default.
3776 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3777 Added silc_client_rekey_callback and silc_client_rekey_final.
3778 Affected files are lib/silcclient/protocol.[ch] and
3779 lib/silcclient/client.[ch].
3781 * Removed the `hmac_key' and `hmac_key_len' fields from the
3782 SilcClientConnection structure; not needed. Affected file is
3783 lib/silcclient/client.h.
3787 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Do not ask whether user wants to use the negotiated private key
3790 for private messages, just use it. Affected file is
3791 silc/local_command.c.
3793 * Added `send_enc_key' and `enc_key_len' fields to the
3794 SilcIDListData structure since they are needed in the re-key
3795 phase. Affected file is silcd/idlist.[ch].
3797 * Implemented the simple re-key protocol into the server.
3798 Affected files silcd/server.c and silcd/protocol.[ch]. The
3799 re-key will be performed once in an hour, by default.
3801 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3802 Added silc_server_rekey, silc_server_rekey_callback and
3803 silc_server_rekey_final.
3805 * Removed Tunneled flag from the protocol. Updated the code
3806 and the specifications.
3808 * Adde `pfs' field to the SilcIDListData to indicate whether
3809 the PFS is to be performed in the re-key. Affected file is
3812 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3814 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3815 int64 of at least the xintXX size. If void * is less that 4
3816 bytes uint32 * will be used. Defined bool as boolean.
3818 * Changed _ALL_ unsigned long and unsigned int to uint32,
3819 unsgined short to uint16 in the source tree.
3821 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3822 not handle clients that has entry->data.registered == FALSE.
3823 They are not in the network anymore. Affected file is
3826 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Implemented the sending of the SERVER_SIGNOFF notify in the
3829 server. Affected file is silcd/server.c.
3831 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3832 Added also silc_notify_payload_encode_args into the
3833 lib/silccore/silcnotify.[ch].
3835 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3836 Affected file silcd/packet_receive.c.
3838 * Implemented the SERVER_SIGNOFF notify handling in the client
3839 library. Affected file lib/silcclient/client_notify.c. Also,
3840 implemnted the printing of the SERVER_SIGNOFF info to the
3841 application. Affected file silc/client_ops.c.
3843 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3844 if the deleting was successful. Affected file silcd/idlist.[ch].
3846 * Added support for public key authentication in the connection
3847 authentication protocol in the client library. Affected file
3848 lib/silcclient/protocol.c.
3850 * Changed the server's silc_idlist_get_clients_by_* interface
3851 to support already allocated array so that new entries may be
3852 added to pre-allocated array. Affected file silcd/idlist.[ch].
3853 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3854 and command replies.
3856 * All command reply functions in the server now calls the
3857 pending command callback even if error occured. This way the
3858 error will be delivered to the client as well. Affected files
3859 silcd/command.c and silcd/command_reply.c.
3861 * Fixed INFO command to return local server's info if no server
3862 was provided. Affected file lib/silcclient/command.c.
3864 * Removed RESTART command for good. Updated the code and the
3867 * Rewrote parts of the task system. It is a bit simpler now.
3868 Removed unsued task priorities. The affected files are
3869 lib/silcutil/silctask.[ch].
3871 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3873 * Moved the USERS printing from the library to the application.
3874 Affected files lib/silcclient/command.c and silc/client_ops.c.
3876 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3880 * Added channel key re-key support. The re-key is perfomed
3881 only by the router and is done once in an hour. Added `rekey'
3882 field to the SilcChannelEntry in the server. Affected files
3883 silcd/server.c and silcd/idlist.h.
3885 * Added silc_task_unregister_by_context into the file
3886 lib/silcutil/silctask.[ch].
3888 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Added SILC_UMODE_GONE mode to indicate when the client is not
3891 present in the SILC network. Added also support to the local
3892 command AWAY that will set this mode. Added support of showing
3893 "xxx is gone" in WHOIS command. The USERS command shows the
3894 gone status as well.
3896 * Fixed setting server and router operator privileges in the
3897 server's UMODE command. Affected file silcd/command.c.
3899 * Merged the SKE KE1 and KE2 payloads into one payload. The
3900 new KE payload is equivalent to the old KE2 payload.
3902 Cleaned up the SKE Start Payload parsing. It now uses the
3903 simple buffer unformatting to do the parsing. A lot faster
3906 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3907 to the SKE that is used to indicate whether both of the SKE
3908 parties should perform authentication. By default only the
3909 responder performs authentication. By setting this flag also
3910 the initiator must do authentication. By default it is unset
3911 since in normal SKE case, client to server connection, only
3912 the responder should do authentication. When doing SKE between
3913 two clients both should perform authentication. Updated the
3914 code and the protocol specs.
3916 * A little fix to IDENTIFY command in the server. Search the
3917 client first by hash not nickname. Affected file is
3920 * Fixed the silc_client_close_connection to support closing
3921 the client to client connections wihtout deleting too much
3922 data. Affected file lib/silcclient/client.c.
3924 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3925 are received if protocol used to be active but is not anymore
3926 the application would crash due to NULL pointer dereference.
3927 Affected files silcd/server.c and lib/silcclient/client.c.
3929 * Added `hash' field to the SilcClientConnection to include
3930 the hash function negotiated in the SKE protocol.
3932 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3933 to set the channel founder authentication data. A client can
3934 claim the founder rights later by providing the authentication
3935 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3936 This way the channel founder can regain the channel founder
3937 privileges even it is left the channel. This works only on
3938 local server and the client must be connected to the same
3939 server to be able to regain the founder rights. Updated the
3940 protocol specs accordingly.
3942 Added support to the CMODE command in the client to set the
3943 founder auth data. Read the README to see how to set it.
3945 Added support to the CUMODE command to claim the founder
3946 rights. Read the README to see how to do it.
3948 Added support for the founder authentication to the Channel
3949 Entry in the server. Affected file silcd/idlist.h.
3951 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3952 server's CMODE command. Affected file silcd/command.c.
3954 * Added the following new functions into lib/silccore/silcauth.[ch]:
3955 silc_auth_get_method and silc_auth_get_data.
3957 * The server now saves the remote hosts public key to the
3958 SilcIDListData pointer. Affected file silcd/protocol.c.
3960 * The normal server now does not remove the channel entry from
3961 the cache if the founder authentication data is set. It used
3962 to remove it if the founder was the last one on the channel on
3963 the server and left the channel. The auth data is saved and
3964 if the channel is re-joined later the old entry is used with
3965 the old auth data. Affected files silcd/command_reply.c and
3968 * Removed the `pkcs' field from the SilcIDListData structure
3969 in the server; it is not used. Affected file silcd/idlist.h.
3971 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Fixed packet processing on slow links. Partial packets were
3974 never re-processed because the incoming data buffer was cleared
3975 by the application. Application must not directly clear the
3976 sock->inbuf, the packet processing routines handle it. Fixed
3977 this in client library and in server.
3979 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Fixed the WHOIS and IDENTIFY send reply function to really
3982 check whether to send list or just one entry. Affected file
3985 * Cleaned up the LEAVE command's channel key distribution. The
3986 affected file silcd/command.c.
3988 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3989 can enforce the channel mode as well. In that case the ID
3990 includes the ID of the server. The code now enforces the
3991 mode change if the router have different mode than the server.
3993 * The notify client operation with CMODE_CHANGE notify can now
3994 return NULL client_entry pointer if the CMODE was not changed
3995 by client. Application must check for this.
3997 * Added <Server ID> argument to INFO command to support server
3998 info fetching by Server ID.
4000 * Added silc_server_announce_get_channel_users to get assembled
4001 packets of channel users of the specified channel. Affected
4002 file silcd/server.[ch].
4004 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4005 was freed underneath the ID Cache.
4007 * Re-announce clients when the server received CHANNEL_CHANGE
4008 notify from the router. Affected file silcd/packet_send.c.
4010 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4013 crashed since it did not handle the fact that there is no cipher
4014 called "3" and didn't check the error condition. Now fixed.
4016 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4017 flag. It can be used to send message requests.
4019 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Implemented the RESTART command in the client.
4023 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4024 notice type messages. Added notice printing to the user
4027 * The channel keys are not re-generated if the channel's mode
4028 is PRIVKEY, ie private key on the channel exists. Affected
4029 files silcd/server.c and silcd/command.c.
4031 * Fixed a little bug in channel message delivery when channel
4032 private keys are set in the server. Affected file is
4033 silcd/packet_send.c.
4035 * Changed the setting on channel->on_channel = TRUE from the
4036 silc_client_save_channel_key to the JOIN command reply. The
4037 key payload is not received if the private channel key is set.
4038 Affected file lib/silcclient/command_reply.c and the
4039 lib/silcclient/client_channel.c.
4041 * When the CMODE_CHANGE notify is sent and the channel private
4042 key mode is removed the channel key must be re-generated in
4043 other cells as well. Added this support for the router in the
4044 silcd/packet_receive.c.
4046 * Added new local command NOTICE to send notice message on
4047 channel. Affected file silc/local_command.[ch].
4049 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Added new local command ME to the client. It is used to send
4052 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4053 some action. Affected file silc/local_command.[ch].
4055 * Changed channel_message and private_message client operations
4056 to deliver the message flags to the application. Added also
4057 the `flags' arguments to the silc_client_send_channel_message
4058 and silc_client_send_private_message functions. Affected file
4061 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Redefined the Private Message Payload to support private message
4064 keys and to support the new private message flags. Updated
4065 the protocol specs. Flags makes it possible to have for example
4066 CTCP style messages.
4068 * Added new type SilcPrivateMessagePayload and defined an API
4069 for it in the lib/silcclient/silcprivate.[ch].
4071 * Tested private message private keys successfully. Tested the
4072 private message key set, unset and list commands with the new
4075 * Redefined the Channel Message Payload to include the channel
4076 message flags (equal with private message flags) to support
4077 for example CTCP style messages.
4079 * Defined some of the message (for channel and private message)
4080 flags. Updated the protocol specs and added the flags to the
4081 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4083 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Added SilcKeyAgreementStatus type to the key agreement routines
4086 to indicate the current status and error if one occured.
4087 The status types are defined in the lib/silcclient/silcapi.h.
4089 * Added new local command KEY that is used to set and unset private
4090 keys for channels, set and unset private keys for private messages
4091 with remote clients and to send key agreement requests and
4092 negotiate the key agreement protocol with remote client. The
4093 key agreement is supported only to negotiate private message keys,
4094 it currently cannot be used to negotiate private keys for channels,
4095 as it is not convenient for that purpose.
4097 * Fixed a minor pending callback setting bug in the function
4098 silc_client_get_client_by_id_resolve, now the function works.
4099 Affected file lib/silcclient/idlist.c.
4101 * Added function silc_net_get_local_port to get local bound
4102 port by socket. Added to lib/silcutil/silcnet.[ch].
4104 * Added `sockets' and `sockets_count' fields to the SilcClient
4105 object. They hold the sockets of the listenning sockets in
4106 the client. Listenning sockets may be for example the key
4107 agreement server. Affected file lib/silcclient/client.[ch].
4108 Added functions the silc_client_add_socket and the
4109 silc_client_del_socket. They are exported to the application
4112 * Added ~./silc/clientkeys to support other client's public keys.
4114 * Renamed verify_server_key client operation to verify_public_key
4115 and added one argument to indicate the type of the connection
4116 (server, client etc.).
4118 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Added silc_server_connection_auth_request to handle the
4121 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4122 silcd/packet_receive.[ch].
4124 * Added silc_server_send_connection_auth_request into the
4125 silcd/packet_send.c to send the connection auth request packet.
4127 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4130 * Fixed the public key authentication in responder side in the
4131 server. The `auth_data' pointer includes the SilcPublicKey
4132 not the path to the public key. Affected file silcd/protocol.c.
4134 * Implemented the public key authentication in the initiator side
4135 in the server. Affected file silcd/protocol.c.
4137 * Removed the [RedirectClient] config section from the server
4138 configuration. Is not needed and I don't want to implement it.
4140 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Cleaned up the CMODE command in the server. It now works
4143 correctly and supports all the modes defined in the protocol.
4144 Affected file is silcd/command.c.
4146 * Added `hmac_name' field to the SilcChannelEntry in the server
4147 to hold the default HMAC of the channel. It can be set when
4148 creating the channel (with JOIN command). Affected files
4151 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4152 type to indicate the change of the current cipher and hmac
4153 on the channel. Client can safely ignore the <cipher> argument
4154 (if it chooses to do so) since the CHANNEL_KEY packet will
4155 force the channel key change anyway. The <hmac> argument is
4156 important since the client is responsible of setting the new
4157 HMAC and the hmac key into use.
4159 * Fixed the CMODE command in the client library as well.
4161 * Tested CMODE command in router environment successfully.
4163 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Show the version of the remote client (or server) when connecting
4166 to the server. It is logged to the log file. Affected file
4167 is silcd/protocol.c.
4169 * Fixed the KILLED notify handling in the client library. The
4170 client must be removed from all channels when receiving the
4173 Also, do not remove the client entry when giving the KILL
4174 command but when the KILLED notify is received.
4176 * Removed silc_idlist_find_client_by_nickname from the server.
4177 Not needed anymore. Affected files silcd/idlist.[ch].
4179 * Implemented the CHANNEL_CHANGE notify type handling to the
4180 server. Affected file silcd/server.c.
4184 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added silc_server_send_notify_invite to send the INVITE
4187 notify between routers.
4189 * Implemented the INVITE command correctly to the server.
4191 * Implemented the INVITE notify type handling in the server.
4193 * Implemented the INVITE command to the client library and on the
4196 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4198 * Added function silc_server_get_client_resolve to find the
4199 client entry by ID from all ID lists and then resolve it
4200 (using WHOIS) if it cannot be found. Affected file is
4203 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Implemented the BAN command to the client library.
4207 * The JOIN command in the server now checks the invite list
4210 * Changed the silc_command_reply_payload_encode_va and the
4211 silc_command_payload_encode_va to support that if argument is
4212 NULL it ignores and checks the next argument. Affected file
4213 lib/silccore/silccommand.c.
4215 * Added silc_server_send_notify_ban to send the BAN notify
4216 type between routers.
4218 * Chaned the silc_notify_payload_encode to support that if
4219 argument is NULL it ignores and checks the next argument.
4220 Affected file lib/silccore/silcnotify.c.
4222 * Tested ban lists in router environment successfully.
4224 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Implemented BAN command to the server, in silcd/command.[ch].
4228 * Removed the BAN and INVITE_LIST modes from the CMODE command
4231 * Added function silc_string_match to regex match two strings.
4232 Affected files lib/silcutil/silcutil.[ch].
4234 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Redefined parts of the SilcChannelEntry in the server to support
4237 the new ban and invite lists.
4239 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Redefined the INVITE command. The same command can be used to
4242 invite individuals to the channel but also to manage the invite
4243 list of the channel (to add to and remove from the invite list).
4244 Updated the protocol specs.
4246 * Added new command SILC_COMMAND_BAN that can be used to manage
4247 the ban list of the channel. Updated the protocol specs.
4249 * Removed the channel modes: the SILC_CMODE_BAN and the
4250 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4251 in the CMODE command. The equivalent features are now available
4252 using INVITE and BAN commands. Updated the protocol specs.
4254 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4255 in the network about change in the current ban list. The notify
4256 type is not used by the client.
4258 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4259 support the invite lists.
4261 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added new function silc_string_regexify that converts string
4264 including wildcard characters into regex string that can
4265 be used by the GNU regex library. Added into the file
4266 lib/silcutil/silcutil.[ch].
4268 Added silc_string_regex_combine to combine to regex strings
4269 into one so that they can be used as one regex string by
4270 the GNU regex library. Added into the file
4271 lib/silcutil/silcutil.[ch].
4273 Added silc_string_regex_match to match two strings. It returns
4274 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4276 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Imported GNU regex to the soruce tree into lib/contrib.
4279 Fixed some compiler warning from the regex.c.
4281 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Fixed MOTD command in the server to work in router environment.
4285 * Fixed the MOTD command in the client library to support
4286 the server argument in the command.
4288 * Added `nickname_len' argument to the silc_idlist_add_client
4289 in the server, as the `nickname' argument may be binary data
4292 * Added silc_idlist_get_channels to return all channels from
4295 * Implemented LIST command to the server. Affected file is
4298 * Implemented the LIST command to the client library and on the
4301 * Added [<user count>] argument to the LIST command reply.
4302 With private channels the user count is not shown.
4304 * Updated TODO and README.
4306 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * The client entry's data.registered must be TRUE even with
4309 global client entry on global client list. The data.registered
4310 is used to check whether the client is anymore in the network,
4311 for example with WHOWAS command so it must be valid.
4313 * Fixed the WHOWAS command in the server. It now actually works
4314 in router environment. Added function into silcd/command_reply.c
4315 silc_server_command_reply_whowas_save.
4317 * Added silc_idlist_purge function to the silcd/idlist.c
4318 to periodically purge the ID Cache.
4320 * Fixed INFO command in the server. It works now in router
4321 environment. Added <server name> argument to the INFO command
4322 reply. Updated the protocol specs.
4324 * Fixed minor bug in silc_idcache_purge to not purge if the
4325 expire value is zero.
4327 * Fixed various bugs in WHOIS and IDENTIFY command handling as
4328 they were buggy because of the WHOWAS information.
4330 * Fixed local command MSG to handle the async resolving of
4331 the remote client properly. It used to fail the first MSG.
4332 Affected file silc/local_command.c.
4334 * Added `data_len' field to SilcIDCache context.
4336 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Update TODO. Todo in commands in the server.
4340 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
4343 used by routers as broadcast packet to inform other routers
4344 about the changed user mode.
4346 Implemented the notify handling in the server. Affected file is
4347 silcd/packet_receive.c. Added the function
4348 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4350 * Added new generic Channel Payload and deprecated the New Channel
4351 Payload. The New Channel Payload is now the generic Channel
4354 * Added new argument `mode' to the silc_server_send_new_channel
4355 as it is required in the Channel Payload now.
4357 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4358 and created a new and real SilChannelPayload to represent the
4359 new generic Channel Payload. Implemented the encode/decode
4360 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4362 * Added silc_server_get_client_channel_list to return the list
4363 of channels the client has joined for WHOIS command reply.
4364 Affected file silcd/server.[ch].
4366 * Implemented the channel list sending in the WHOIS command reply
4367 in server and in the client.
4369 Implemented the channel list displaying on the user interface
4370 as well. Affected file silc/client_ops.c.
4372 * Added silc_channel_payload_parse_list to parse list of Channel
4373 Payloads. It returns SilcDList list of SilcChannelPayloads.
4374 Client for example can use this function to parse the list of
4375 channels it receives in the WHOIS command reply. The caller
4376 must free the list by calling silc_channel_payload_list_free.
4377 Affected files lib/silccore/silcchannel.[ch].
4379 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Added one new argument <user mode> to the WHOIS command reply
4382 to return the mode of the user in SILC. Updated the protocol
4385 Implemented it to the server and client.
4387 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Fixed the mode printing on the user interface on joining.
4390 Affected file silc/client_ops.c.
4392 * Implemented the UMODE command and user modes in general to the
4393 client library and to the user interface.
4395 * Implemented the UMODE command to the server.
4397 * The server now sends UNKNOWN_COMMAND error status if client sends
4398 unknown command. Affected file silcd/command.c.
4400 * All server commands now handle the command identifier the right
4401 way when sending the command reply to the client. The client can
4402 use to identify the command replies with the identifier.
4404 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Added silc_server_get_client_route to resolve the route to
4407 the client indicated by the client ID. Affected file is
4410 * Added silc_server_relay_packet as general function to relay
4411 packet to arbitrary destination. This deprecates functions
4412 like _send_private_message_key, _relay_notify etc. Affected
4413 file is silcd/packet_send.[ch].
4415 Removed silc_server_send_key_agreement,
4416 silc_server_send_private_message_key and
4417 silc_server_packet_relay_notify functions from the file
4418 silcd/packet_send.[ch].
4422 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4423 server. Affected file silcd/packet_receive.[ch].
4425 * Implemented the KILL command to the client. Implemented the
4426 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4427 Affected files lib/silcclient/command[_reply].c and
4428 lib/silcclient/client_notify.c. Implemented the KILL notify
4429 printing in the user inteface.
4431 * Fixed a lot silc_parse_nick memory leaks from the client
4432 library in the file lib/silcclient/command.c.
4434 * Changed the silc_server_send_notify_on_channels's `sender'
4435 argument from SilcSocketConnection to SilcClientEntry to
4436 check the sender as entry and not as connection object and not
4437 to send to the client provided as argument. The affected file
4438 is silcd/packet_send.[ch].
4440 * The notify packets that are destined directly to the client used
4441 to not to be processed by the server. Now changed that and the
4442 server processes all notify packets. After relaying the packet
4443 to the client the notify packet is processed in the server.
4445 * The silc_server_free_client_data now checks whether there is
4446 pending outgoing traffic for the client and purges the data to
4447 the network before removing the client entry.
4449 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4452 an client is killed from the SILC Network. Updated the protocol
4455 Added new function silc_server_send_notify_killed to the
4456 silcd/packet_send.[ch].
4458 * Added function silc_server_packet_relay_notify to relay notify
4459 packets that are destined directly to a client. In this case
4460 the server does not process the notify packets but merely relays
4461 it to the client. Affected file silcd/packet_send.[ch].
4463 Added also silc_server_packet_process_relay_notify to check
4464 whereto relay the notify. Affected file is
4465 silcd/packet_receive.[ch].
4467 * Implemented the KILL command to the server.
4471 * Added the backup schema desgined last fall to the protocol
4472 specs for everyone to see. The specification is in the
4473 *-spec-xx.txt draft and the packet type definitions for the
4474 backup routers is in *-pp-xx.txt draft. Thusly, added also
4475 new packet type SILC_PACKET_CELL_ROUTERS.
4477 * A big security problem in the implementation discovered. The
4478 signoff of an client did not cause new channel key generation
4479 which it of course should've done. The channel keys must be
4480 always re-generated when client leaves (or signoffs) the channel.
4481 The silc_server_remove_from_channels funtion now handles
4482 the channel key re-generation.
4484 * Added `sender' argument to the silc_server_send_notify_on_channels
4485 to not to send the client provided as argument. Affected file
4486 silcd/packet_send.[ch].
4488 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Implemented OPER and SILCOPER commands into the server and
4493 * Added silc_auth_verify and silc_auth_verify_data to verify
4494 the authentication directly from the authentication payload.
4495 It supports verifying both passphrase and public key based
4496 authentication. Affected file lib/silccore/silcauth.[ch].
4498 * Added `hash' field to the SilcIDListData structure. It is the
4499 hash negotiated in the SKE protocol. Affected file is
4502 * Slight redesigning of the SilcAuthPayload handling routines.
4503 Do not send SilcPKCS but SilcPublicKey as argument.
4505 * Implemented the public key authentication support to the
4506 serverconfig. The public key is loaded from the provided path
4507 and saved as authentication data to void * pointer. Thus,
4508 changed the unsigned char *auth_data to void *auth_data;
4510 * Fixed SHUTDOWN command to send the reply before the server
4511 is shutdown. :) Affected file silcd/command.c.
4513 * Fixed fatal bug in CONNECT command. The hostname was invalid
4514 memory and server crashed. Affected file silcd/command.c.
4516 * Fixed fatal bug in CLOSE command. The server_entry became
4517 invalid but was referenced later in the command. Affected file
4520 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Fixed fatal bug in failure packet handling. Server ignored
4523 the failure and thus crashed when it came.
4527 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4529 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4530 that the command may be executed only once in (about) 2 seconds.
4531 The old SILC_CF_LAG flag is same but allows command bursts up
4532 to five before limiting.
4534 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4535 server code. Various commands now includes the CF_LAG_STRICT
4536 flag to disallow any kind of miss-use of the command.
4538 * Fixed the silc_buffer_unformat to not to allocate any data
4539 if the length of the data is zero. It used to allocate the
4540 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4542 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Changed the format of AdminConnection configuration section
4545 in the server. Added username of the admin to the format.
4546 Affected files silcd/serverconfig.[ch].
4548 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4549 to return admin configuration data by host, username and/or
4552 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Implemented WHOWAS command to the server. Added the functions:
4556 silc_server_command_whowas_parse,
4557 silc_server_command_whowas_send_reply,
4558 silc_server_command_whowas_from_client and
4559 silc_server_command_whowas_from_server
4561 * Added <Client ID> argument to the WHOWAS command reply. Updated
4562 the protocol specs accordingly.
4564 * Implemented WHOWAS command and command_reply to the client
4567 Implemented the WHOWAS printing on the user interface.
4569 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added new argument to the WHOWAS command reply, the real name.
4572 It is an optional argument. Updated the protocol specs.
4574 * Added SilcIDCacheDestructor callback that is registered when
4575 the SilcIDCache is allocated. The callback is called when
4576 an cache entry in the ID Cache expires, or is purged from the
4577 cache. Added into lib/silccore/idcache.[ch].
4579 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4580 to destruct the client entries when the cache entry expires.
4581 Other ID Cache's in server and in the client library ignores
4584 * If the ID Cache entry's `expire' field is zero then the entry
4585 never expires. Added boolean `expire' argument to the
4586 silc_idcache_add function in the lib/silccore/idcache.[ch].
4587 If it is TRUE the default expiry value is used.
4589 * Added silc_server_free_client_data_timeout that is registered
4590 when client disconnects. By default for 5 minutes we preserve
4591 the client entry for history - for WHOWAS command.
4593 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Added support to the server to enforce that commands are not
4596 executed more than once in 2 seconds. If server receives
4597 commands from client more frequently, timeout is registered
4598 to process the commands. Affected file silcd/command.c.
4599 Added new function silc_server_command_process_timeout.
4601 * Changed NICK_NOTIFY handling in client library to check that
4602 if the client's nickname was changed, so there is no need to
4603 resolve anything from the server.
4605 * Removed error printing from the WHOIS and IDENTIFY commands.
4606 If error occurs then it is ignored silently in the client library.
4607 The application, however, may map the received error to
4608 human readable error string. The application currently maps
4609 the NO_SUCH_NICKNAME error to string.
4611 * Made the command status message public to the application. Moved
4612 them from lib/silcclient/command_reply.c to
4613 lib/silcclient/command_reply.h. The application can map the
4614 received command status to the string with the
4615 silc_client_command_status_message function.
4617 * Added check to the server to check that client's ID is same
4618 as the Source ID in the packet the client sent. They must
4621 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Added dist-bzip hook to the Makefile.am to make bzip2
4624 compressed distributions.
4626 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Server now enforces the maximum length for the nickname and
4629 the channel as protocol specification dictates. 128 bytes for
4630 nickname and 256 bytes for channel name.
4632 * Moved the WHOIS printing to the application. The client libary
4633 does not print out the WHOIS information anymore, the application
4634 must do it. Renamed silc_client_command_reply_whois_print to
4635 the silc_client_command_reply_whois_save.
4637 The client's idle time is also sent to the application now, and
4638 the idle is shown on screen.
4640 * Added silc_client_command_reply_identify_save to save the
4641 received IDENTIFY entries.
4643 * Do not check for channel private keys in message sending and
4644 reception if the channel does not have the PRIVKEY mode set.
4645 Affected file lib/silclient/client_channel.c.
4647 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4650 just surfaced after chaning the JOIN procedure.
4652 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Added silc_client_get_clients_by_list to get client entries
4655 from Client ID list, that is returned for example by JOIN
4656 and USERS command replies. The application should use this
4657 function for example when JOIN command reply is received to
4658 resolve the clients already on the channel (library does not
4659 do that anymore as USERS command reply is not used in the JOIN
4660 procedure anymore). Affected files lib/silcclient/silcapi.h and
4661 lib/silcclient/idlist.c.
4663 * JOIN command reply and USERS command reply returns now SilcBuffer
4664 pointers instead of unsigned char pointers when returning
4665 the client list and mode list.
4667 * Added <Client ID> argument to the JOIN command reply, mainly
4668 for the server to identify for which client the command was
4669 originally sent. Updated protocol specs accordingly.
4671 * Added SilcDlist private_key pointer to the SilcChannelEntry
4672 in the client to support the channel private keys. Affected
4673 file is lib/silcclient/idlist.h.
4675 * Added SilcChannelPrivateKey argument to the function
4676 silc_client_send_channel_message so that application can choose
4677 to use specific private ke if it wants to. If it is not provided,
4678 the normal channel key is used, unless private keys are set.
4679 In this case the first (key that was added first) is used
4680 as the encryption key.
4682 * Implemented the support for channel private key handling.
4683 Implemented the following functions:
4685 silc_client_add_channel_private_key,
4686 silc_client_del_channel_private_keys,
4687 silc_client_del_channel_private_key,
4688 silc_client_list_channel_private_keys and
4689 silc_client_free_channel_private_keys
4691 Affected file lib/silcclient/client_channel.c.
4693 * Added the support for the private keys in the channel message
4694 sending and encryption and in the message reception and
4695 decryption. Affected funtions are
4696 silc_client_send_channel_message and silc_client_channel_message.
4698 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4700 * Added SKE's key verify callback to the client library's
4701 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4703 * Removed the statement that server (or router) must send USERS
4704 command reply when joining to the channel so that the client
4705 knows who are on the channel. Instead, the client list and
4706 client's mode list is now sent in the JOIN command reply to the
4707 client who joined channel. This is better solution.
4709 * Added function silc_server_get_users_on_channel and function
4710 silc_server_save_users_on_channel to the silcd/server.[ch].
4712 * Removed function silc_server_command_send_users from the
4715 * Do not show topic on the client library anymore. The topic is
4716 sent in the command reply notify to the application and the
4717 application must show the topic now.
4719 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Added client searching by nickname hash into the IDENTIFY and
4722 WHOIS commands in the server as they were clearly missing from
4723 them. Affected file is silcd/command.c.
4725 * Fixed a bug in private message receiving in the client library.
4726 The remote ID was freed and it wasn't supposed, now it is
4729 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Minor fix to the channel payload; allocate the data area, as it
4732 needs to be of specific length.
4734 * If the key agreement port is zero then the operating
4735 system will define the bound port. Affected files are
4736 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4738 * Added new function silc_channel_payload_decrypt into the file
4739 lib/silccore/silcchannel.[ch].
4741 * Moved the channel message etc, check from silc_packet_decrypt
4742 to applications. The library calls now a generic
4743 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4744 when the packet is either normal or special. This was done to
4745 allow more wide range of checking that was not allowed when
4746 the code was in library. Now applications can do virtually any
4747 checks to the packet and return to the library the decision how
4748 the packet should be processed. Affected files are
4749 lib/silccore/silcpacket.[ch].
4751 Added silc_server_packet_decrypt_check to the server and
4752 silc_client_packet_decrypt_check to the client library.
4754 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4755 to send with specified source and destination information.
4757 * Channel message delivery between routers was broken after the
4758 channel key distribution was fixed earlier. The channel key
4759 was used be to distributed to other routers as well which is not
4760 allowed by the protocol. Now this is fixed and channel keys
4761 really are cell specific and the channel message delivery between
4762 routers comply with the protocol specification.
4764 * Fixed various commands in server to check also the global list
4765 for the channel entry and not just the local list. The affected
4766 file silcd/command.c.
4768 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added assert()s to buffer formatting and unformatting routines
4771 to assert (if --enable-debug) when error occurs. Affected
4772 file: lib/silcutil/silcbuffmt.c.
4774 * Changed to auto-reconnect to check whether the remote host is
4775 router and register the re-connect timeout if it is. It used
4776 to check that whether we are normal server, but router must do
4777 auto-reconnect with another router as well. Affected file
4780 * Removed the [<key len>] option from CMODE command as the cipher
4781 name decides the key length, nowadays. See the defined ciphers
4782 from the protocol specification.
4784 * Added [<hmac>] option to the CMODE command to define the HMAC
4785 for the channel. Added SILC_CMODE_HMAC channel mode.
4787 * Added [<hmac>] option for the JOIN command so that user can
4788 select which HMAC is used to compute the MACs of the channel
4791 * Added Hmac field to the Channel Message Payload. The integrity
4792 of plaintext channel messages are now protected by computing
4793 MAC of the message and attaching the MAC to the payload. The
4794 MAC is encrypted. Now, it is clear that this causes some
4795 overhead to the size of the packet but rationale for this is that
4796 now the receiver can verify whether the channel message decrypted
4797 correctly and also when private keys are set for the channel the
4798 receiver can decrypt the packet with several keys and check from
4799 the MAC which key decrypted the message correctly.
4801 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4802 lib/silccrypt/silccipher.[ch].
4804 * Added silc_hash_len to return the digest length into the
4805 lib/silcrypt/silchash.[ch].
4807 * Rewrote parts of Silc Channel Payload interface in the
4808 lib/silccore/silcchannel.[ch]. The encode function now also
4809 encrypts the packet and parse function decrypts it.
4811 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Fixed a minor formatting bug in the SKE's key material processing.
4814 It actually might have processed the keys wrong way resulting
4817 * Redefined the mandatory HMAC algorithms and added new algorithms.
4818 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4819 and hmac-md5 truncated to 96 bits. The mandatory is now
4820 hmac-sha1-96. Rest are optional (including the one that used
4821 to be mandatory). Rationale for this is that the truncated HMAC
4822 length is sufficient from security point of view and can actually
4823 make the attack against the HMAC harder. Also, the truncated
4824 HMAC causes less overhead to the packets. See the RFC2104 for
4827 * Added new [hmac] configuration section. The SKE used to use
4828 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4829 is of course wrong. The official names that must be proposed in
4830 the SKE are the ones defined in the protocol specification
4831 (hmac-sha1-96 for example). The user can configure any hmac
4832 using any hash function configured in the [hash] section. At
4833 least, the mandatory must be configured.
4835 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4837 * Added HMAC list to the SKE proposal list. It has now both
4838 hash algorithm list and HMAC list. This makes the protocol
4839 incompatible with previous versions. The SKE now seems to work
4840 the way it is supposed to work, for the first time actually.
4842 * Defined plain Hash algorithms to the protocol specification.
4845 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Implemented support for key agreement packets into the server.
4848 Added functions silc_server_key_agreement and
4849 silc_server_send_key_agreement. Other than these functions,
4850 server has nothing to do with this packet.
4852 * Added support for private message key packets into the server.
4853 Added functions silc_server_private_message_key and
4854 silc_server_send_private_message_key.
4858 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4859 called in the protocol's final callback instead in the END
4860 protocol state. This makes a little more sense and in the same
4861 time in client we can use the same protocol routines for normal
4862 key exchange and to key agreement packet handling as well.
4864 * Added to both client's and server's KE protocol context the
4865 SilcSKEKeyMaterial pointer to save the key material. We will
4866 bring the key material to the protocol's final callback by doing
4867 this. The final callback must free the key material.
4869 * Added SKE's packet_send callback into client's KE protocol
4870 context so that the caller can choose what packet sending function
4871 is used. This way we can use different packet sending when
4872 doing normal SKE when doing key agreement packet handling (in
4873 the key agreement packet handling we do not want to encrypt
4876 * Implemented the responder side of the key agreement routines
4877 in the client. The client can now bind to specified port and
4878 accept incoming key negotiation. The key material is passed
4879 to the application after the protocol is over.
4881 * Implemented the processing of incoming Key Agreement packet
4882 in the client. Added function silc_client_key_agreement to
4885 * Implemented the intiator side of the key agreement routines
4886 in the client. The client can now initiate key agreement with
4887 another remote client. The key material is passed to the
4888 application after the protocol is over.
4890 * Created client_keyagr.c to include all the key agreement
4893 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4894 SILC_TASK_CALLBACK except that it is not static.
4896 * Created client_notify.c and moved the Notify packet handling
4897 from the client.[ch] into that file.
4899 * Created client_prvmsg.c and moved all private message and
4900 private message key routines from the client.[ch] into that file.
4902 * Create client_channel.c and moved all channel message and
4903 channel private key routines from the client.[ch] into that file.
4905 * Changed silc_client_get_client_by_id_resolve to resolve with
4906 WHOIS command instead of IDENTIFY command, in the file
4907 lib/silclient/idlist.c.
4909 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Implemented the SKE's responder side to the Client library.
4913 * When FAILURE is received to the protocol do not trust it
4914 blindly. Register a timeout to wait whether the remote closes
4915 the connection as it should do it, only after that process the
4916 actual failure. This was changed to both client and server.
4918 * Added client_internal.h to include some of the structures
4919 there instead of client.h in lib/silcclient/.
4921 * Added function silc_task_unregister_by_callback to unregister
4922 timeouts by the callback function.
4924 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4926 * Some "Incomplete WHOIS info" errors has been appearing on the
4927 log files. Took away the entry->userinfo check from WHOIS
4928 reply sending. The entry->userinfo is now " " if client did not
4929 provide one. I thought this was fixed earlier but something
4930 is wrong still. Let's see if the error still appears.
4932 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Fixed a minor bug in the login when the channel key is
4935 re-generated in the server. It used to generate the key in
4936 wrong order and thus caused problems in the channel traffic.
4938 * Fixed a minor bug in channel key distsribution after
4939 KICK command. The key was not sent to the router even though
4942 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Added silc_ske_process_key_material_data as generic routine
4945 to process any key material as the SILC protocol dictates. The
4946 function is used by the actual SKE library but can be used by
4947 applications as well. This relates to the private message keys
4948 and the channel private keys since they must be processed the
4949 same way the normal SILC session keys. The protocol dictates
4950 this. Affected files: lib/silcske/silcske.[ch].
4952 Added also silc_ske_free_key_material to free the
4953 SilcSKEKeyMaterial structure.
4955 * Defined silc_cipher_set_key function to set the key for
4956 cipher without using the object's method function. The affected
4957 files: lib/silccrypt/silccipher.[ch].
4959 * Implemented silc silc_client_add_private_message_key,
4960 silc_client_add_private_message_key_ske,
4961 silc_client_del_private_message_key,
4962 silc_client_list_private_message_keys and
4963 silc_client_free_private_message_keys functions in the
4966 Added functions silc_client_send_private_message_key to send
4967 the Private Message Key payload and silc_client_private_message_key
4968 to handle incoming Private Message Key payload.
4970 * Added Cipher field to the Private Message Key payload to set
4971 the cipher to be used. If ignored, the default cipher defined
4972 in the SILC protocol (aes-256-cbc) is used.
4974 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Removed lib/silcclient/ops.h file.
4978 Redefined parts of the SILC Client Library API. Created new
4979 file silcapi.h that deprecates the ops.h file and defines the
4980 published Client Library API. Defined also private message key
4981 API and channel private key API into the file.
4983 This is the file that the application must include from the
4984 SILC Client Library. Other files need not be included by
4985 the application anymore.
4987 * Added new key_agreement client operation callback and also
4988 defined the Key Agreement library API for the application.
4990 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4993 is used by clients to request key negotiation between another
4994 client in the SILC network. If the negotiation is started it
4995 is performed using the SKE protocol. The result of the
4996 negotiation, the secret key material, can be used for example
4997 as private message key.
4999 Implemented the Key Agreement payload into the files
5000 lib/silccore/silauth.[ch].
5002 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Redefined ciphers for the SILC protocol. Added some new ciphers
5005 and defined the key lengths for the algorithms. Changed the
5006 code accordingly. The default key length is now 256 bits.
5008 * Fixed SKE key distribution function silc_ske_process_key_material
5009 when the key length is more than 128 bits. The default key
5010 length in SILC is now 256 bits.
5012 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5013 to indicate unsupported algorithm.
5015 * Renamed rijndael.c to aes.c and all functions as well.
5017 * Fixed a long standing channel key setting bug in client library.
5018 Weird that it has never surfaced before.
5020 * Fixed bug in channel deletion. If the entire channel is removed
5021 then it must also delete the references of the channel entry
5022 from the client's channel list as the client's channel entry and
5023 the channel's client entry share same memory.
5025 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Implemented CONNECT and SHUTDOWN commands in the client.
5029 * Implemented CLOSE command to the client.
5031 * Added the function silc_idlist_find_server_by_name into the
5032 files silcd/idlist.[ch].
5034 Added the function silc_idlist_find_server_by_conn into the
5035 files silcd/idlist.[ch].
5037 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * DIE command was renamed to SHUTDOWN. Updated the both code
5042 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5043 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5045 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5048 * Added function silc_server_create_connection function to create
5049 connection to remote router. My server implementation actually
5050 does not allow router to connect to normal server (it expects
5051 that normal server always initiates the connection to the router)
5052 so the CONNECT command is only good for connecting to another
5055 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5058 or some other client was kicked from the channel.
5060 Implemented the handling of the notify type to both client
5063 Implemented silc_server_send_notify_kicked to send the KICKED
5064 notify. It is used to send it to the server's primary router.
5066 * Implemented the KICK command into server and client.
5068 * Added `query' argument to the silc_idlist_get_client function
5069 to indicate whether to query the client from server or not if
5072 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5073 to indicate that the client is not channel founder.
5077 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Removed the rng context from SilcPacketContext structure and
5080 changed that the packet routine uses the Global RNG API.
5082 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Added support for quit message that client can "leave" on the
5085 channel when it quits the SILC. It is ditributed inside the
5086 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5088 Added silc_server_free_client_data that will take the
5089 signoff message as argument.
5091 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5093 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Updated parts of the protocol specification to keep it up
5098 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5101 payloads in one packet.
5103 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5104 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5105 use now the new List flag.
5107 * Also deprecated the following packet types: REPLACE_ID,
5108 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5110 * Added list support for Notify packet in server.
5112 * Added silc_server_send_notify_channel_change to send the
5113 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5114 the silc_server_send_replace_id.
5116 * Added silc_server_send_notify_nick_change to send the
5117 NICK_CHANGE notify type. Deprecates the function
5118 silc_server_send_replace_id.
5120 * Added silc_server_send_notify_join to send the JOIN notify type.
5121 Deprecates the function silc_server_send_new_channel_user.
5123 * Added silc_server_send_notify_leave to send LEAVE notify type.
5124 Deprecates the function silc_server_send_remove_channel_user.
5126 * Added silc_server_send_notify_cmode and
5127 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5128 types. Deprecates the silc_server_send_set_mode function.
5130 * Added SERVER_SIGNOFF notify type to indicate that server has
5131 quit. This means that all clients on the channel from that
5132 server will drop. This can be also used when netsplit happens.
5134 Deprecated REMOVE_ID packet type since it is not needed anymore
5137 Added silc_server_send_notify_server_signoff to send the
5138 SERVER_SIGNOFF notify type. Deprecates the function
5139 silc_server_send_remove_id.
5141 Added also silc_server_send_notify_signoff to send the
5142 SIGNOFF notify type.
5144 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5145 SILC protocol from this day on. Changed the protocol
5146 specification as well.
5148 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5149 notify type. It is used between routers to notify about
5150 topic changes on a channel.
5152 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5155 * Partly updated the protocol specification to comply with the
5156 changes now made. It is still though a bit outdated.
5158 * The JOIN notify type now takes one extra argument <Channel ID>.
5159 The packet used to be destined to the channel but now the
5160 JOIN type may be sent as list thus it is impossible to
5161 destine it to any specific channel. By adding this argument
5162 it is again possible.
5164 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Added CREDITS file. The CHANGES and CREDITS file will appear
5167 in the distribution as well.
5169 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5172 types in the server's silcd/packet_receive.c.
5174 * Implemented CMODE and CUMODE to work in router environment.
5176 * Fixed minor encoding and decoding buglet from the
5177 lib/silccore/silcmode.c.
5179 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5182 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5184 * Changed all SilcConfigServer* and silc_config_server* to
5185 SilcServerConfig* and silc_server_config*, respectively.
5188 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Associated the ID (client or server ID) to the Authentication
5191 Payload to avoid any possibility of forging. Updated the
5192 protocol specification and the code accordingly.
5194 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * The RSA key length is now save to the RsaKey context in the
5197 key generation process in lib/silccrypt/rsa.c. The key length
5198 is now used to figure out the maximum size of the block allowed
5199 to be encrypted/signed.
5201 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5202 is equivalent to the silc_mp_mp2bin but does not allocate any
5205 * Changed silc_mp_mp2bin API to take length argument. If it is
5206 non-zero then the buffer is allocated that large. If zero, then
5207 the size is approximated using silc_mp_sizeinbase, which however
5210 * Created Global RNG API which is global RNG that application can
5211 initialize. After initializing, any routine anywhere in the
5212 code (including library) can use RNG without allocating a new
5213 RNG object. This was done to allow this sort of use of the
5214 RNG in code that has no chance to allocate RNG object. All
5215 applications currently allocate this and many routines in the
5216 library use this. Affected file lib/silccrypt/silcrng.[ch].
5218 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5219 it to use the Global RNG API.
5221 * Defined Authentication Payload into protocol specification that
5222 is used during SILC session to authenticate entities. It is
5223 used for example by client to authenticate itself to the server
5224 to obtain server operator privileges.
5226 Implemented this payload into the lib/silccore/silcauth.[ch].
5227 Implemented also routines for public key based authentication
5228 as the new protocol specification dictates.
5230 Moved definitions of different authentication methods from
5231 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5233 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5234 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5235 silc_pkcs_verify_with_hash functions into the file
5236 lib/silccrypt/silcpkcs.[ch].
5238 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * The client entry's userinfo pointer must be always valid.
5241 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5242 will fail since it requires the userinfo. Now, the userinfo
5243 is allocated as "" if actual userinfo does not exist. Actually,
5244 it must exist and it is totally Ok to drop client connections
5245 that does not announce the userinfo. However, we will make
5246 this workaround for now.
5248 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5249 to return the remote port by socket.
5251 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5254 SILC_SERVER_PENDING_EXEC and added an new macro
5255 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5256 data or when error occurs while processing the pending command.
5258 Added new argument `destructor' into silc_server_command_pending
5259 and to the SilcServerCommandPending object. This destructor is
5260 now called after calling the pending callback or if error occurs
5261 immediately. If error occurs the actual pending callback won't
5262 be called at all - only the destructor. The destructor may be
5263 NULL if destructor is not needed.
5265 All this applies for client library code as well. Similar
5266 changes were made there as well for the pending commands.
5268 In the client, the application must now allocate the
5269 SilcClientCommandContext with the silc_client_command_alloc
5272 * Added reference counter to the SilcServerCommandContext. Added
5273 function silc_server_command_alloc and silc_server_command_dup
5276 Same type of functions added to the client library for the same
5279 * Removed the cmd_ident from IDListData away since it is now
5280 global for all connections. It is the command identifier used
5281 in command sending and with pending commands. The affected file
5284 * Added reference counter to the SilcSocketConnection objecet to
5285 indicate the usage count of the object. The object won't be
5286 freed untill the reference counter hits zero. Currently only
5287 server uses this, and client ignores it. The client must be
5288 set to use this too later. The affected files are
5289 lib/silccore/silcsockconn.[ch]. Added also the function
5290 silc_socket_dup to increase the reference counter.
5292 This was mainly added because it is possible that the socket
5293 is removed underneath of pending command or other async
5294 operation. Now it won't be free'd and proper DISCONNECTING
5295 flags, etc. can be set to avoid sending data to connection that
5296 is not valid anymore.
5298 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5299 the connection. After that it sets SILC_SET_DISCONNECTED.
5300 It is, however, possible that the socket data is not still freed.
5301 The silc_server_packet_process now checks that data is not
5302 read or written to connection that is DISCONNECTED. The socket
5303 get's freed when the reference counter hits zero.
5305 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Changed the client operation API: channel_message operation's
5308 `sender' is now the client entry of the sender, not the nickname
5309 and the `channel' is the channel entry, not the channel name.
5311 In the private_message operation the `sender' is now also the
5312 client entry of the sender not the nickname.
5314 Affected file is lib/silcclient/ops.h and all applications
5315 using the client operations.
5317 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Moved the calling of ops->connect() from connect_to_server_final
5320 into receive_new_id functin since that is the point when the
5321 client is actually allowed to send traffic to network. The
5322 affected file is lib/silcclient/client.c.
5324 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5327 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5328 (if needs broadcasting) instead of broadcasting the packets one
5329 by one which would make a burst in the network traffic.
5331 * Added `broadcast' argument to the functions in silcd/server.[ch]
5332 silc_server_create_new_channel[_with_id] to indicate whether
5333 to send New Channel packet to primary router.
5335 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added new function into the silcd/server.[ch] files:
5338 silc_server_create_new_channel_with_id to create new channel with
5339 already existing Channel ID.
5341 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5342 lib/silccore/silcpacket.h. This packet is used t send list of
5343 Set Mode payloads inside one packet. Server uses this to set
5344 the modes for the channels and clients on those channels, that it
5345 announced to the router when it connected to it. The protocol
5346 specification has been updated accordingly.
5348 * The silc_server_new_channel did not handle the packet coming
5349 from normal server as it normally does not send that. However,
5350 when it announces its channels it does send it. Implemented
5351 the support for that.
5353 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5354 into the file lib/silccore/id.h.
5356 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Fixed memory leaks in the functions silc_idlist_del_client,
5359 silc_idlist_del_channel and silc_idlist_del_server in the file
5360 silcd/idlist.c. All of those leaked like a sieve.
5362 * Fixed some small memory leaks in the client's function
5363 silc_client_notify_by_server.
5365 * Added functions into silcd/server.c: silc_server_announce_clients,
5366 silc_server_announce_channels and silc_server_announce_server.
5367 These functions are used by normal and router server to announce
5368 to its primary router about clients, channels and servers (when
5369 router) that we own. This is done after we've connected to the
5372 These functions effectively implements the following packet types:
5373 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5374 and SILC_PACKET_NEW_ID_LIST.
5376 * Added new functions into the silcd/packet_receive.[ch]:
5377 silc_server_new_id_list, silc_server_new_channel_list and
5378 silc_server_new_channel_user_list to handle the incoming
5379 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5381 * Added support of changing Channel ID in the function
5382 silc_server_replace_id. If the server that announces a channel
5383 to the router already exists in the router (with same name but
5384 with different Channel ID), router is responsible to send
5385 Replace ID packet to the server and force the server to change
5386 the Channel ID to the one router has.
5388 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5389 client that the Channel ID has been changed by the router. The
5390 normal server sends this to the client. Client must start using
5391 the new Channel ID as the channel's ID.
5393 Implemented handling of this new type into lib/silcclient/client.c
5394 into the function silc_client_notify_by_server.
5396 * Added new function silc_idlist_replace_channel_id into the files
5397 silcd/idlist.[ch] to replace the Channel ID.
5399 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Call silc_server_command_identify_check always when processing
5402 the IDENTIFY command in silcd/command.c
5404 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5407 send keepalive packets. The packet can be sent by clients,
5408 servers and routers.
5410 Added function silc_socket_set_heartbeat into the file
5411 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5412 If not set, the heartbeat is not performed. The actual
5413 heartbeat is implemented in the low level socket connection
5414 library. However, application is responsible of actually
5417 Added silc_server_send_heartbeat to send the actual heartbeat
5418 packet into silcd/packet_send.[ch]. Server now performs
5419 keepalive with all connections.
5421 * Added silc_task_get_first function into lib/silcutil/silctask.c
5422 to return the timeout task with shortest timeout. There was a bug
5423 in task unregistration that caused problems. TODO has been
5424 updated to include that task system must be rewritten.
5426 * The client library will now resolve the client information when
5427 receiving JOIN notify from server for client that we know but
5428 have incomplete information.
5430 * Rewrote parts of silc_server_remove_from_channels and
5431 silc_server_remove_from_one_channel as they did not remove the
5432 channel in some circumstances even though they should've.
5434 * Encryption problem encountered in server:
5436 The LEAVE command used to send the Channel Key packet to the
5437 router immediately after generating it. However, the code
5438 had earlier sent Remove Channel user packet but not immediately,
5439 ie. it was put to queue. The order of packets in the router
5440 was that Channel Key packet was first and Remove Channel User
5441 packet was second, even though they were encrypted in the
5442 reverse order. For this reason, MAC check failed. Now, this
5443 is fixed by not sending the Channel Key packet immediately but
5444 putting it to queue. However, this is more fundamental problem:
5445 packets that are in queue should actually not be encrypted
5446 because packets that are sent immediately gets encrypted
5447 actually with wrong IV (and thus MAC check fails). So, packets
5448 that are in queue should be encrypted when they are sent to
5449 the wire and not when they put to the queue.
5451 However, the problem is that the current system has not been
5452 designed to work that way. Instead, the packet is encrypted
5453 as soon as possible and left to the queue. The queue is then
5454 just purged into wire. There won't be any fixes for this
5455 any time soon. So, the current semantic for packet sending
5458 o If you send packet to remote host and do not force the send
5459 (the packet will be in queue) then all subsequent packets to the
5460 same remote host must also be put to the queue. Only after the
5461 queue has been purged is it safe again to force the packet
5464 o If you send all packets immediately then it safe to send
5465 any of subsequent packets through the queue, however, after
5466 the first packet is put to queue then any subsequent packets
5467 must also be put to the queue.
5469 Follow these rules and everything works fine.
5471 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Added new function silc_server_remove_clients_by_server to
5474 remove all client entries from ID list when the server connection
5475 is lost. In this case it is also important to invalidate all
5476 client entires as they hold the invalid server entry. This
5477 fixes fatal bug when server has lost connection and will reconnect
5480 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Made some sanity checks to silc_server_daemonise like to check
5483 whether the requested user and group actually exists.
5485 * Added sanity check to SKE's silc_ske_responder_finish to check
5486 that the public and private key actually is valid.
5488 * Invalidate the client's nickname when receiving Replace ID
5489 packet and the Client ID is being replaced. This means that the
5490 server will query the nickname if someone needs it (client)
5493 * Sort the ID Cache in client library when the ID Cache data
5494 has changed (needs sorting).
5496 * Do not allow for SILC client to create several connections to
5497 several servers. The client does not support windows right now
5498 and generating multiple connections causes weird behaviour.
5500 Irssi-silc client does support windows and can handle several
5501 connections without problems, see: www.irssi.org and SILC plugin.
5503 * Fixed some places where client was added to the IDList. The
5504 rule of thumb is following (in order to get everything right):
5505 If the client is directly connected local client then the
5506 `connection' argument must be set and `router' argument must be
5507 NULL to silc_idlist_add_client function. If the client is not
5508 directly connected client then the `router' argument must
5509 bet set and the `connection' argument must be NULL to the
5510 silc_idlist_add_client function.
5512 * The funtion silc_server_packet_send_local_channel actually did
5513 not check whether the client was locally connected or not. It
5514 does that now. Fixed a bug related to LEAVE command.
5516 * Fixed Remove Channel User payload parsing bug in server's
5517 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5519 * The server's silc_server_save_channel_key now checks also the
5520 global ID list for the channel as it might not be in the local
5521 list. Fixed a bug related to LEAVE command.
5523 * Is this the end of the [<unknown>] buglet that has been lurking
5524 around for a long time? A little for loop fix in server's
5525 silc_server_command_whois_parse that is used by both IDENTIFY
5526 and WHOIS command. At least, this was a clear bug and a cause
5527 of one type of [<unknown>] buglet.
5529 * WHOIS and IDENTIFY commands call the function
5530 silc_server_command_[whois/identify]_check function even if
5531 we are not router server.
5533 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added --with-gmp configuration option. If set the GMP
5536 is always compiled in the SILC source tree. If not set then
5537 it is checked whether the system has the GMP3 installed. If
5538 it has then the GMP won't be compiled (the system's headers
5539 and library is used), if it doesn't have it then the GMP is
5540 compiled in the SILC source tree.
5542 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Changed RSA private exponent generation to what PKCS #1
5545 suggests. We try to find the smallest possible d by doing
5546 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5547 not security fix but optimization.
5549 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Added new config entry [Identity] to fork the server and run
5552 it as specific user and group. A patch from Bostik.
5554 * Imported Dotconf configuration library into lib/dotconf.
5555 This will be used to create the SILC configuration files later.
5556 It will appear in the distsribution after this commit.
5558 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * A big code auditing weekend happening. Auditing code for
5561 obvious mistakes, bugs and errors. Also, removing any code
5564 Removed files for being obsolete:
5566 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5567 inline in the file lib/silcutil/silcbuffer.h)
5569 o lib/silcutil/silcbufutil.c (the header has inline versions)
5571 Changed code to fix possible error conditions:
5573 o The buffer formatting routines now check that the destination
5574 buffer really has enough space to add the data. This applies for
5575 both buffer formatting and unformatting
5576 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5577 unformatting was changed to accomodate following rules:
5578 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5579 sent to the function while XXX_*STRING will not allocate or copy
5580 the data into the buffer. Instead it sets the pointer from the
5581 buffer into the pointer sent as argument (XXX_*STRING used to
5582 require that the pointer must be allocated already). This change
5583 makes this whole thing a bit more consistent and more optimized
5584 (note that the data returned in the unformatting with XXX_*STRING
5585 must not be freed now). The routines return now -1 on error.
5587 o Tried to find all code that use buffer_format and buffer_unformat
5588 and added return value checking to prevent formatting and
5589 especially unformatting errors and possible subsequent fatal
5592 o Changed ske->x and ske->KEY to mallocated pointers in
5593 lib/silcske/silcske.h. Fixed possible data and memory leak.
5595 o Added return value checking to all *_parse* functions. Fixed
5596 many memory leaks as well.
5598 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5599 so that buffer overflows would not happen. All code now also
5600 checks the return value as it can fail.
5602 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Added reconnection support to server if the normal server looses
5605 its connection to the router (for example if router is rebooted).
5606 The server performs normal reconnection strategy implemented
5607 to the server. Affected file silcd/server.c.
5609 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added new packet type SILC_PACKET_SET_MODE that is used to
5612 distribute the information about changed modes (for clients,
5613 channels and clients channel modes) to all routers in the
5614 network. Updated the protocol specification accordingly.
5616 Added functions into silcd/packet_send.c and
5617 silcd/packet_receive.c: silc_server_send_set_mode,
5618 silc_server_set_mode.
5620 Added new files silcmode.[ch] into lib/silccore that implements
5621 the encoding and decoding of Set Mode Payload. Added new type
5622 SilcSetModePayload. Moved the definitions of different modes
5623 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5625 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Oops, a little mistake in server's connection authentication
5628 protocol. The protocol is not ended with FAILURE but with
5629 SUCCESS if the authentication is Ok. :) Affected file is
5632 * Implemented NICK_CHANGE notify handling in server in the file
5633 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5634 the local clients on the channel. After the changing nickname
5635 in router environment snhould work and the [<unknown>] nickname
5636 should appear no more.
5638 The silc_server_replace_id function that receives the Replace ID
5639 payload now sends the NICK_CHANGE notify type also in the file
5640 silcd/packet_receive.c
5642 * Changed WHOIS and IDENTIFY command to support the maximum amount
5643 of arguments defined in protocol specs (3328 arguments). This
5644 fixed a bug that caused problems when there were more than three
5647 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Added extra parameter, command identifier, to the
5650 silc_client_send_command so that explicit command identifier
5653 Changed that ID list routines uses specific command identifier
5654 when sending WHOIS/IDENTIFY requests to the server so that they
5655 can be identified when the reply comes back.
5657 Affected files lib/silcclient/command.[ch],
5658 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5660 * Added `sender' argument to silc_server_packet_send_to_channel
5661 to indicaet the sender who originally sent the packet to us
5662 that we are now re-sending. Ignored if NULL. Affected file
5663 silcd/packet_send.[ch].
5665 * Added some server statistics support in silcd/server_internal.h
5666 SilcServerStatistics structure and around the server code. Also
5667 send some nice statistics information when client is connecting
5670 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Fixed channel ID decoding in server's JOIN command reply in
5673 silcd/command_reply.c
5675 * Fixed braodcasting of replace ID payload to not to send it if
5676 we are standalone server in silcd/packet_receive.c.
5678 * Fixed all channel message sending routines to not to send
5679 packets to clients that has router set, since they are routed
5680 separately in the same function earlier. Affects file
5681 silcd/packet_send.c and all channel packet sending functions.
5683 * In USERS reply, res_argv[i] are not allocated, the table
5684 is allocated. Thus changed that free the table, not its
5687 * In server's whois_check and identify_check if the client is
5688 locally connected do not send any WHOIS commands - they are not
5691 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Fixed some minor bugs in client when sending WHOIS command. The
5694 arguments was in wrong order.
5696 * Removed statis function add_to_channel from server in
5697 silcd/command.c that was previously used with the joining but
5700 * Tested USERS command in router environment successfully with two
5701 routers, two servers and two clients.
5703 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Reorganized the USERS command and command reply in client library
5706 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5707 When the command is given by user we register a pending command
5708 callback that will reprocess the command after the reply has been
5709 received from the server. When reprocessing the packet we then
5710 display the information. Thus, the USERS information is displayed
5711 now in the command callback instead of in the command reply
5712 callback. The processing of the command is same as previously
5713 when server has sent the command reply in the JOINing process.
5715 * Added to USERS command in silcd/command_reply.c to join the client,
5716 we didn't use to know about, to the channel after we've created
5717 a client entry for it. Also, for clienet we did know already still
5718 check whether it is on the channel or not and add it if not.
5720 * Removed silc_server_command_join_notify as the function and its
5723 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5725 * Changed the client's pending command handling to the same as the
5726 server's pending command handling. It is also now possible to
5727 execute command reply functions from other command reply
5728 function as the function callbacks for commands and command
5729 replies are one and same. The pending commands are not static
5730 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5731 in client connection context. Thus, pending commands are server
5732 connection specific as it is convenient.
5734 Changed the function silc_client_command_pending and
5735 silc_client_command_pending_del and added new function
5736 silc_client_command_pending_check. Removed the
5737 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5740 * Added cmd_ident, current command identifier, to the client
5741 connection context in lib/silcclient/client.h to keep track on
5742 command identifiers used in command sending. Client's command reply
5743 function handling now supports the mandatory command identifiers.
5745 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5746 funtions in client to fully support pending command callbacks.
5748 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5749 as one of the arguments to the application in the command reply
5752 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5753 before first releasing SILC but came back. Now it is removed again
5754 and should come back nomore. The FORWARDED flag was used only
5755 by the JOINing procedure by forwarding the command packet to router.
5756 Now, the JOINing procedure has been changed to more generic (due
5757 to various router environment issues) and FORWARDED is not needed
5758 anymore for anything. The protocol specification is yet to be
5761 Now, removed silc_server_packet_forward from server and the flag
5762 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5764 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Renamed NAMES command to USERS command. The NAMES was named that
5767 due to historical reasons. Now it is renamed. Also, rewrote
5768 parts of the USERS command. The nickname list is not sent anymore
5769 by the server. Only Client ID and mode lists are sent in the USERS
5770 command. Changed this also to the protocol specification.
5772 The client now resolves the names and stuff after it receives
5773 the USERS list from the server when joining to the channel.
5775 * WHOIS and IDENTIFY commands has been changed to support multiple
5776 Client ID's per command. One can now search for multiple users
5777 in the network by sending only one WHOIS or IDENTIFY command.
5778 Changed the code and the protocol specifications.
5780 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5781 uses silc_server_command_whois_parse to parse the request. */
5783 * If normal server, do not parse the WHOIS and IDENTIFY requests
5784 before sending it to the router. Saves some time.
5786 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Fixed JOIN command on client library. Wrong number of arguments
5789 used to crash the client.
5791 * Added silc_server_channel_has_global function to check whether
5792 channel has global users or not.
5794 * Added silc_server_channel_has_local function to check whether channel
5795 has locally connected clients on the channel.
5797 * The silc_server_remove_from_one_channel now checks whether the
5798 channel has global users or not after given client was removed from
5799 the channel. It also checks whether the channel has local clients
5800 on the channel anymore. If it does not have then the channel entry
5801 is removed as it is not needed anymore.
5803 * The silc_server_notify now checks on JOIN notify whether the joining
5804 client is one of locally connected or global. If it is global then
5805 the channel has now global users on the channel and that is marked
5806 to the channel entry. Also, it now saves the global client to
5807 global list who is joining and JOINs it to the channel. This is
5808 for normal server, that is.
5810 Changed silc_server_send_notify_on_channel,
5811 silc_server_packet_relay_to_channel and
5812 silc_server_packet_send_to_channel check if we are normal server
5813 and client has router set (ie. global client) do not send the
5814 message to that client, as it is already routed to our router.
5816 * Implemented LEAVE notify type handling in silc_server_notify
5819 * Tested LEAVE command in router environment successfully. Tested
5820 with two routers, two servers and two clients.
5824 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5826 * Implemented SIGNOFF notify type handling in silc_server_notify
5829 * silc_server_remove_id now removes the client entry from all channels
5830 it has joined and thusly sends SIGNOFF notify type.
5832 * Rewrote the NAMES list generation in server by removing two excess
5833 loops. The lists are created now inside one loop.
5835 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * silc_server_remove_channel_user checks now also global list
5838 for channel and client.
5840 * silc_server_new_channel_user checks now both local and global
5841 list for channel and client. Fixed a bug in client id decoding.
5842 Used to decode wrong buffer.
5844 * silc_server_channel_message checks now both local and global
5845 list for channel entry.
5847 * Tested channel joining (hence JOIN) in router environment
5848 successfully. Tested with two routers, two servers and two
5851 * Tested channel message sending in router environment successfully.
5853 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Added silc_server_save_channel_key into server.[ch] to save the
5856 received channel key in Channel Key payload processing. It is
5857 also used in JOIN command reply handling.
5859 Equivalent function silc_client_save_channel_key added into
5860 client.[ch] into client library.
5862 * Changed JOIN command reply to send information whether the channel
5863 was created or not (is existing already) and the channel key
5864 payload. Changed protocol specs accordingly.
5866 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5867 the request was sent by ID and not by nickname. Crashed on
5870 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5873 now correctly save the received data.
5875 * silc_server_free_sock_user_data now notifies routers in the
5876 network about entities leaving the network.
5878 At the same time implemented functions silc_server_remove_id
5879 and silc_server_send_remove_id to receive and send REMOVE_ID
5880 packets. The packet is used to notify routers in the network
5881 about leaving entities. The ID removed will become invalid in
5884 * Added function silc_idlist_del_server into server. Removes and
5885 free's server entry from ID list.
5887 * silc_server_private_message function now checks, if we are router,
5888 that the destination ID really is valid ID, naturally.
5890 * In router when NEW_ID packet is received (for new client) the
5891 hash of the Client ID is saved in the ID Cache but the
5892 client->nickname is set to NULL, instead of putting the hash
5895 IDENTIFY command now also checks that client->nickname must be
5896 valid. If it is not if will request the data from the server who
5897 owns the client. Added new function
5898 silc_server_command_identify_check.
5900 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5901 to set the command to already allocated Command Payload.
5903 * Tested private message sending in router environment with two
5904 routers, two servers and two clients. Fixed minor bugs and now
5907 * Fixed segfault from client's NAMES command. Used to crash if
5910 * Forwarded packets must not be routed even if it is not destined
5911 to the receiver. Changed server code comply with this.
5913 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added `require_reverse_mapping' boolean value to ServerParams
5916 structure. If TRUE (not default) the server will require that
5917 the connecting host has fully qualified domain name.
5919 If the reverse mapping is not required and hostname could not be
5920 found the IP address is used as hostname.
5922 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Implemented version string checking to both client and server.
5925 The check is incomplete currently due to the abnormal version
5926 strings used in development version of SILC.
5928 * Changed all command functions in server to use the new
5931 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Changed char *data to unsigned char *data in ID Cache system to
5934 support binary data as ID Cache data. Changed code to support
5935 binary data in lib/silccore/idcache.c.
5937 * Renamed silc_server_packet_relay_command_reply to
5938 silc_server_command_reply as it is normal packet receiving
5939 function. Rewrote the function to accept command replys for
5940 servers and not only for clients.
5942 * Mark remote router always as registered server if we are connecting
5943 to it. Otherwise, commands sent by the router to us are ignored.
5945 * All ID List find routines now returns the ID Cache Entry pointer
5946 as well if requested.
5948 * WHOIS command works now in router environment, tested with two
5949 routers, two servers and two clients.
5951 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5952 in router environment (as it is almost equivalent to WHOIS) but
5953 hasn't been tested thoroughly. Added new functions:
5955 silc_server_command_identify_parse
5956 silc_server_command_identify_send_reply
5957 silc_server_command_identify_from_client
5958 silc_server_command_identify_from_server
5960 * Disabled route cache adding because adding two different ID's with
5961 same IP replaces the old cache entry thus giving wrong route.
5962 The entry->router->connection is always the fastest route anyway
5963 so route cache may not be needed. Of course, new routes maybe
5964 established after receiving the ID when the entry->router->connection
5965 might not be anymore the most optimal.
5967 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Add route cache for received ID for fast routing.
5971 * Added silc_server_packet_route to route received packet on router
5972 that is not destined to us.
5974 * Renamed silc_server_get_route to silc_server_route_get.
5976 * Added id_string and id_string_len fields into SilcServer to
5977 include encoded ServerID for fast comparing without excess
5978 encoding of the ID's.
5980 * Cleaned up WHOIS command on server side. Added following static
5983 silc_server_command_whois_parse
5984 silc_server_command_whois_check
5985 silc_server_command_whois_send_reply
5986 silc_server_command_whois_from_client
5987 silc_server_command_whois_from_server
5989 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5990 arguments in command replies. All command functions should be
5991 updated to use this macro.
5993 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Minor typo fixes on command reply handling on server.
5997 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added silc_server_command_add_to_channel internal routine to add
6000 the client to the channel after router has created the channel and
6001 sent command reply to the server.
6003 * Added generic silc_server_send_command to send any command from
6006 * Use static buffer with ID rendering instead of duplicating data.
6008 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Fixed a channel user mode bug when joining to a channel server gave
6011 everybody channel founder rights, oops.
6013 * We mark ourselves as the router of the incoming server connection
6014 if we are router ourselves. This way we can check in some packet
6015 sending functions whether it is locally connected server. For
6016 incoming router connections we put NULL.
6018 * For router sending packets locally means now always sending the
6019 packet cell wide; to local clients and local servers. For normal
6020 server sending packet locally means sending it to only local
6023 * Fixed the JOIN command to really work in router environment. If the
6024 channel is created it is always created by the router. Router is
6025 also responsible of making the initial joining to the channel,
6026 sending JOIN notify to the sending server and distributing
6027 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6028 does not exist server doesn't do anything else but forward the
6029 command to the router which performs everything.
6031 * Added silc_server_send_channel_key function to send the Channel Key
6034 * Added silc_server_create_channel_key to create new channel key. The
6035 channel key is now re-generated everytime someone joins or leaves
6036 a channel, as protocol dictates. Note: channel->key_len is the
6039 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6042 packet_receive.[ch] to separate packet sending and receiving
6043 routines. The server.[ch] now includes everything else including
6044 actual packet processing (writing and reading data) and other
6047 Renamed silc_server_private_message_send_internal to
6048 silc_server_send_private_message. The routine is still though
6049 used only to relay private messages as server does not send
6050 private messages itself.
6052 Renamed silc_server_new_channel to silc_server_create_new_channel
6053 and added new function sicl_server_new_channel that handles the
6054 incoming New Channel packet. Added also new sending function
6055 silc_server_send_new_channel to send New Channel Payload.
6057 * Added new function silc_server_notify to process incoming notify
6058 packet to the server/router. Server may then relay the notify
6059 to clients if needed.
6061 * Added new function silc_server_new_channel_user to process incoming
6062 New Channel User packet. Router will redistribute the packet and
6063 send JOIN notify to its local clients and locally connected servers
6064 if needed. Normal server will send JOIN notify to its local client
6065 on same channel when received this packet. Added also corresponding
6066 sending function silc_server_send_new_channel_user to sent the
6069 * Added boolean route argument to send_notif_to_channel and
6070 packet_send_to_channel functions to attempt to route the packet
6071 if it is TRUE and send only locally if it is FALSE.
6073 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * silc_server_replace_id now broadcasts the received replace ID
6076 packet if it is not broadcast packet already. The router must
6077 broadcast to inform other routers about changed ID.
6079 * Added backpointer to server's router into SilcServer context in
6080 silcd/server_internal.h.
6082 * Fixed silc_server_packet_broadcast to send correct broadcast
6085 * The channel key is now distributed to the local client as soon
6086 as it is received from the router (in router environment) so that
6087 no other packet may be sent for the channel until client has
6090 * silc_server_remove_channel_user now broadcasts the received
6091 Remove Channel User packet if it is not broadcast packet already.
6092 The router must broadcast to inform other routers about removed
6095 * Added users field into SilcPacketContext that is a reference count
6096 of the context. One can increase the reference count by calling
6097 silc_packet_context_dup which is now changed to just increase the
6098 reference count instead of duplicating the data. The reference
6099 count is decresed by calling silc_packet_context_free that will
6100 free the data after the reference count hits zero.
6102 For now on the packet context and everything allocated into it
6103 (including the raw packet from network) must be freed by calling
6104 the new silc_packet_context_free function. Added also new function
6105 silc_packet_context_alloc that must be used now to allocate the
6106 context. This also means that if a routine is asynchronous from
6107 silc_[client/server]_packet_parse_type the packet context must
6108 be duplicated by calling silc_packet_context_dup. Otherwise it
6109 gets free'd after silc_[client/server]_packet_parse_type returns.
6110 Also, one must remember that if packet is duplicated then its
6111 reference count must be decresed by calling the free function as
6112 many times as it was duplicated.
6114 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6115 from both client and server.
6117 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Made joining to a channel working in router environment.
6121 * Cleaned up JOIN command on server side and create function
6122 silc_server_command_join_channel internal routine to make the
6125 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Changed silc_command_pending list to SilcDList. Also, added
6128 `ident' field to SilcServerCommandPending structure to identify
6129 the reply and to call correct callback.
6131 Added silc_server_command_pending_check function to replace the
6132 corresnponding macro. The silc_command_pending list is not
6135 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6136 to set identifier to previously allocated Command Payload. It
6137 is used to set identifier for command when resending Command
6140 * Added silc_command_payload_encode_payload to encode Command
6141 Payload buffer from SilcCommandPayload structure.
6143 * Added silc_argument_payload_encode_payload to encode Argument
6144 payload buffer from SilcArgumentPayload structure.
6146 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Changed WHOIS command to support router connection on server side.
6149 The whois request is always sent to router unless the server is
6150 standalone server. After server has received the reply from the
6151 router will it send the reply to the client.
6153 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6154 broadcast received broadcast packet. The function is used only
6155 by router. The broadcast packet is always sent to the router's
6158 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6159 render given ID to printable string, for log files for example.
6161 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Made basic router to router connections working. At least they
6164 can now connect to each other but nothing really works the way
6165 they are supposed - yet.
6167 * Added new initiator token to RouterConnection configuration
6168 file in silcd/serverconfig.[ch]. It is used to tell whether we
6169 are the initiator to the remote router or whether we'll expect
6170 the other end to connect.
6172 * Moved registering of listener task to silc_server_init, hence
6173 the server starts listenning as soon as it is run, even if it
6174 does not have connections to other routers. Let's see how well
6177 * Changed default connection retry timeouts for more suitable in
6180 * Removed cipher and such arguments from silc_idlist_add_client
6181 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6182 Added new function silc_idlist_add_data to add the keys and stuff
6185 * Added SilcIDListData structure and added it to SilcClientEntry
6186 and SilcServerEntry as their first field in the structure. This
6187 way we can explicitly cast the ID entries to the SilcIDListData
6188 structure and get common data for the entries. In past, we had
6189 to first check what type of connection it is and then cast it to
6190 correct ID entry type. Now, we can directly cast the opaque
6191 pointer to the SilcIDListData (no matter what ID entry it actually
6192 is) and get the data needed.
6194 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6197 in some circumstances even if threre were timeout tasks, though not
6198 IO tasks, but tasks anyway. Now fixed.
6200 * Defined SilcServerConnection structure to hold connection specific
6201 stuff about directly connected servers and routers. The definition
6202 is currently in silcd/server_internal.h. I thought about having
6203 a bit more important role fro this struct but for now it is used
6204 only when connecting to other server (or router actually).
6206 * Added connecting retry support in server when connecting to
6207 router(s). The retry feature implement exponential backoff
6208 algorithm. Also, added SilcServerParams structure to hold default
6209 parameters for server. For now, it include these retry settings
6210 and are hard coded. After server is moded to be as Silc Server
6211 Library this structure will be more important.
6213 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Changed client librarys channel->clients table to SilcList and
6216 changed code accordingly.
6218 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6220 * Changed client's channel table to SilcList and changed code
6221 accordingly. Also changed SilcChannelClientEntry to include back-
6222 pointer to the channel so that client entry can use that structure
6223 as list as well and we have fast cross-reference to the channel.
6224 This change dramatically decreased the complexity of channel
6225 handling with client entry and vice versa (removed one extra
6226 loop when searching for channel entry from many functions).
6228 * Changed server->sim from table to SilcDList and changed code
6231 * NAMES command can now be used from user interface. It will show
6232 the user list on the channel, neatly.
6234 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6235 Code now saves realname of the user if it becomes available.
6237 * Renamed configure.in to configure.in.pre and made ./prepare
6238 script to automatically add correct version string to
6239 configure.in which it creates from configure.in.pre.
6241 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * NAMES command reply now shows users mode with the nickname when
6246 * Moved silc_client_ch[u]mode[_char] functions from
6247 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6248 place sucks, they are utility functions and should be in some
6251 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6253 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6256 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Added TRQ (efficient deque and list library) into lib/trq. This is
6261 a very good list library that is currently used in the SILC. Defined
6262 SilcList API over the library because I didn't like the API very
6263 much. See lib/trq/silclist.h for the API and examples of how to
6264 use the API. Fixed various places in the code to use the new
6265 SilcList API. The SilcList is meant for lists that has a structure
6266 already defined as a list. It is not suitable to add just some
6267 context to the list (in TRQ, the context is the list actually).
6269 So, I defined SilcDList that can be used for the purpose where
6270 predefined list structure does not exit. This can be used as
6271 such list. Now some context just can be added to the SilcDList.
6272 Currently this list is not used in the SILC just yet, though there
6273 are a lot places where this can replace dynamically allocated
6274 tables and I will fix these places, later, to use SilcDList.
6275 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6276 and use TRQ internally).
6278 Also fixed some annoying warning messages that the original TRQ
6279 code generated. Also minor changes to TRQ's Makefile.in.
6281 * Added support for querying by Client ID to both WHOIS and
6282 IDENTIFY commands into server, as required by the protocol.
6284 * Removed method function pointers from SilcBuffer structure. They
6285 weren't used to anything and just increased the context size for
6286 no good reason. This change also made silc_buffer_alloc and
6287 silc_buffer_free functions inline functions.
6289 * Disabled command flooding detection support until it's fixed so
6290 that it accepts commands in but does not execute them more than once
6293 * Added silc_net_localhost(), to return local hostname, into
6294 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6295 that must be initialized before calling silc_client_init.
6297 * Added new function: silc_server_send_notify_on_channels to send
6298 notify messages to all channels client has joined. It is assured
6299 that the message is sent only once per client.
6301 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6302 lib/silcutil/silcutil.[ch] as silc_format function. The new
6303 function is generic and is used by server as well, not only by
6304 the logging routines.
6306 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6307 the provided version string was not acceptable. Added new function:
6308 silc_ske_check_version into lib/silcske/silcske.h. The function
6309 must be implemented by the application (client or server) and it
6310 does not reside in the SKE library. The function checks the version
6311 string remote end sent.
6313 * Added back pointers (to opaque context and to SilcSocketConnection)
6314 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6316 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6317 duplicate packet context structure.
6319 * Changed `notify' client operation to send same arguments as client
6320 receives from server except for ID's. ID's are mapped to correct
6321 ID entry and that is returned. Also, if channel entry is not sent
6322 by server but the notify is for channel the channel entry is sent
6323 to application (otherwise application doesn't know that it is for
6324 channel (library gets it from packet's Destination ID)).
6326 * Added silc_client_remove_from_channels into client library to
6327 remove a client from all channels it has joined to. Used when
6328 received SIGNOFF notify from server. Added also new function
6329 silc_client_replace_from_channels to replace old ID entry with
6330 new ID entry on all channels. Used when received NICK_CHANGE
6333 * Fixed ID Cache list handling in silc_idlist_get_client in
6334 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6335 to get (or query) client by ID.
6337 * Updated TODO list.
6339 * Added connection authentication status message defined by the
6340 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6341 support for these into the code in client and server side.
6343 * Added generic function silc_client_send_command to send any command
6344 with variable argument list. Application should use this function
6345 to send commands if the command functions provided by the library
6346 does not suite for the application's user interface needs.
6348 * Added new `failure' client operation. Application is notified about
6349 received failure packet if client is executing a protocol. In this
6350 case the protocol's execution has failed.
6352 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6353 is required by the protocol.
6355 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6356 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6359 * Added status flag to SilcSKE object to indicate realtime status
6360 of the SKE protocol.
6362 * Application receives now exactly same command reply arguments as
6363 the library receives from server. However, if ID is received the
6364 corresponding ID entry is returned to the application (eg. Client
6365 ID is mapped to correct SilcClientEntry entry and that is returned).
6366 Changed command_reply client operation due to this change.
6368 * Changed all ID's in commands and in command replys as ID Payloads.
6369 Change affected both client and server side codes.
6371 All ID's sent in SILC network (with execption of ID's in SILC
6372 Packet header) are sent in ID Payload to support variable length
6375 * Server now notifies nick changes and notifies all clients on
6376 the channels about the new nickname (about the new Client ID,
6379 * Implemented CMODE command to change channel modes. Supports all
6380 channel modes defined by the protocol specs except ban and invite
6381 lists. (Also, private channel key mode is supported but support for
6382 setting private channel key in client is missing, thus, this mode
6383 has no effect on client side (except that server requires that the
6384 client uses private channel key and normal channel traffic does not
6387 Also, invite mode works per se, but INVITE command does not work
6388 yet correctly, so you can set channel as invite only channel but
6389 inviting clients to the channel does not work (it is yet to be
6390 thought what's the best way to do it).
6392 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6393 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6394 Implemented CUMODE command to change user's mode on the channel.
6395 Supports all modes defined by the protocol specs.
6397 * Added NAMES command reply to return users modes on the channel.
6399 * Removed unnecessary and slow ciphers from lib/silccrypt.
6401 * Set SO_KEEPALIVE option to connection sockets by default.
6403 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6405 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6406 redefined the Notify Payload into protocol specs.
6408 * Added silc_id_payload_parse_id to get ID directly from raw
6411 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6413 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6414 accept searching by Client ID as well.
6416 * Added support for LEAVE and SIGNOFF notify types in client library.
6418 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6419 to parse ID Payload from raw data.
6421 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Added flags parameter into silc_ske_assemble_security_properties
6424 function in lib/silcske/silcske.[ch].
6426 * Changed notify client operation to fit better for notify messages
6427 sent by server. The notify payload received from server is now
6428 passed to the application (after parsing it to SilcNotifyPayload).
6429 It is application's responsibility to retrieve the arguments
6430 from the payload and show the message the way it wants. The message
6431 sent by server is implementation specific.
6433 * Changed public keys to comply with the protocol specification.
6434 Old public keys are not supported anymore and are not compatible.
6436 * Removed nickname from Channel Payload as the latest draft removed
6437 it. The client must resolve the nickname from the NAMES command
6438 reply received when it joined the channel.
6440 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6442 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Fixed some errors in protocol specification drafts.
6446 * Created lib/silccore/silcnotify.c to implement Notify Payload
6447 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6448 generic payloads described by protocol specifications. The file
6449 includes implementations for ID Payload and Argument Payload.
6451 * Changed Command Payload implementation to use the new Argument
6452 Payload. Changed command_xxxx_payload to command_payload_xxxx
6453 to comply with SILC coding conventions.
6455 * Added suppport for Argument Payload handling in Notify Payload
6456 implementation as protocol requires it. Added the new support
6457 into server and client lib as well.
6459 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Added support for multiple nicknames on same channel. [n] is
6462 added locally to the nickname if there are more than one same
6463 nicknames on the channel.
6465 * Server now sends all nicknames that matched WHOIS request.
6466 Client also shows the list received from server.
6468 * Added TOPIC command to client side. User can now set and show
6469 current topic on channel.
6471 * Added MOTD command to client and server. Also, server sends the
6472 motd when client connects to the server.
6474 * Changed version strings to comply ISO 8601.
6476 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Fixed protocol error handling in client library. It should now
6479 cope even if the SKE fails for some reason.
6481 * Made new protocol specification drafts for submitting to IETF.
6483 * Implemented TOPIC command to server in silcd/command.c.
6485 * Added two new notify types into lib/silccore/silcnotify.h:
6486 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6487 notify nickname change and topic setting/change on a channel.
6489 * API change of command_reply operation in client library. The
6490 application gets now the status type received from server as well.
6492 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6494 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6496 * Cras fixed and optimized the packet handling even further and
6497 it should work now. Minor change to the prototype of function
6498 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6500 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Added new function into lib/silcutil/silcschedule.[ch]:
6503 silc_schedule_with_fd to select() a specified fd. The function
6504 returns after timeout expires or data arrives or goes. The
6505 function is used by packet routines to wait that all data is
6506 received from network.
6508 * Fixed data reading from network in lib/silccore/silcpacket.c.
6509 The code now assures that all data is read from the fd and then
6510 continues packet processing. This was a bug fix since the code
6511 used to drop some data in some circumstances.
6513 * Added new function into lib/silcclient/client.[ch]:
6514 silc_client_start_key_exchange to start key exchange after
6515 connection has been established to server. The code internally
6516 now uses this funtion but its main purpose was to provide it
6517 for applications that perform their own connecting. After
6518 application has created a connection it merely calls this
6519 function to start the key exchange between client and server.
6520 The library takes care of everything else after that.
6522 Updated also lib/silcclient/README to explain the usage of
6525 * Do not send to application information that connection has
6526 been established. Application gets notified it by connect
6529 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Applied cras's patch to add silc_schedule_one function. The
6532 function runs scheduler once and returns.
6534 * Fixed the scheduler after cras messed it up. The timeout
6535 handling works now as it's supposed to work.
6537 * Added into lib/silccore/ silcnotify.h to include notify
6538 message types support. Changed silc_server_send_notify*
6539 functions, in server.[ch], to support those new notify types.
6540 Added the support for the notify types into client library,
6541 as well. Added new notify client operation into ops.h in
6544 * Changed silc_server_packet_send_to_channel to send normal
6545 packets instead of just channel message packets. The function
6546 is now used to send the notify packets to channels. It is not
6547 used to send channel message packets anymore, as server never
6550 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6551 va_arg()s as it seems to require it nowadays. I guess, if SILC
6552 is compiled with older va_arg() the new code should work anyway.
6554 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Splitted core library. Core library (lib/silccore) includes
6557 now only SILC protocol specific core (and common) components.
6558 Created new utility library (lib/silcutil) that includes more
6559 generic purpose stuff. The stuff for util library was taken
6560 from the old core library. This was minor and easy split.
6562 * Created SILC Client Library (lib/silcclient) that includes
6563 implementation of the SILC client without user interface. This
6564 was major move from silc/ directory. The code has been changed
6565 so that it is transparent towards the user interface. The
6566 silc/ directory includes now the same user interface as before
6567 and it uses the new client library. Read lib/silcclient/README.
6568 Basicly, the client library performs everything else related
6569 to SILC except user interface handling. Also, configuration
6570 files are considered to be part of user interface and library
6571 does not handle them.
6573 This change also changed a lot of structures, function naming etc.
6574 Most important change was that SilcClientWindow object was
6575 renamed to SilcClientConnection in the client library. Created
6576 also new file lib/silcclient/ops.h. Also added new files
6577 silc/local_command.[ch] and silc/client_ops.[ch].
6579 All these changes were made to make it easier for user interface
6580 designers to create what ever user interface for the SILC client
6583 It is also expected that the server will be moved to lib
6584 directory as well and SILC Server Library will be created;
6585 sometimes in the future.
6587 * Removed Local commands from lib/silccore/silccommand.h as
6588 they are application specific and new client library does not
6589 handle any of those anymore.
6591 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6592 old client implementation in silc/.
6594 * Added support for callback functions in SILC_LOG_* macros.
6595 Application can now set its own callbacks that will be called
6596 instead of using the default functions that will always print
6597 the debug messages to stderr (or stdout). Also, debugging can
6598 now be disabled by setting silc_debug to FALSE and re-enabled by
6599 setting it to TRUE. Note, that logging will still work even
6600 if debugging is disabled.
6602 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6603 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6604 silc_log_reset_debug_callbacks.
6606 * To enable debugging in silc client one must give now -d
6607 option on command line.
6609 * Changed silc_schedule_init to automatically allocate task queues
6610 if they are not allocated before calling it.
6612 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added GMP 3.1 into math library.
6616 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6619 a channel in SILC network. The packet is used by servers and
6620 routers to notify other routers that user has left a channel.
6621 This little feature was missing until now. Added the feature
6622 to protocol specification as well.
6624 Added functions: silc_server_send_remove_channel_user and
6625 silc_server_remove_channel_user into server.[ch].
6627 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6628 lib/silccore/silcpacket.h. However, they are not implemented
6631 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Fixed joining to a channel and sending channel messages
6634 between server and router. The channel message sending should
6635 now work inside a cell.
6637 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6639 * Fixed the private message sending between server and router.
6640 The private message sending should now work inside a cell.
6642 * Added silc_server_replace_id into server.[ch] to replace
6643 existing ID in the SILC network.
6645 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6646 and silc_idlist_replace_server_id into idlist.[ch] in server.
6648 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6650 * Fixed the server to server connections. Server can again now
6651 connect to router. Router to router connections probably does
6654 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Added dynamic protocol registering support. Now protocols can
6657 registered and unregistered on the fly. Patch by cras.
6659 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Added lib/contrib directory to hold routines that some platforms
6662 don't have but are needed by SILC.
6664 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6665 into lin/contrib to provide getopt() and getopt_long() for
6666 those who don't have it.
6668 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Added AWAY command to client. When away message is set and
6671 client receives a private message packet the client automatically
6672 replies to the sender with the away message.
6674 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6675 bug seemed to be the cause of recent problems when compiling
6678 * Added version detection support to SKE protocol specification
6679 and added the new changes to the SKE implementation as well.
6680 There were other minor changes in the SKE protocol as well.
6682 Many changes in lib/silcske/silcske.[ch] and in
6683 lib/silcske/payload.[ch].
6685 * Added ^U functionality, clear input line. Patch from cras.
6687 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Mainly small bugfixes on core library. Fixed some debugging
6690 logging and buffer overflow in silclog.c.
6692 * Updated config.sub and config.guess on the distribution tree.
6694 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * Added command lagging support in server. Client may execute
6697 commands now only once in two seconds.
6699 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6701 * Optimized packet reception. MAC computation and checking is now
6702 also more optimized. A lot previously duplicated code is now
6703 used as generic by both client and server.
6705 * Fixed key pair generation in clientutil.c
6707 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Added into lib/silccore/silcbufutil.[ch] new function;
6710 silc_buffer_realloc.
6712 * Moved generic packet sending/encryption functions to
6713 lib/silccore/silcpacket.[ch] from client and server. Some
6714 rewriting of the functions.
6716 * Moved all generic packet reception/decryption functions to
6717 lib/silccore/silcpacket.[ch] from client and server. The
6718 packet processing is now much cleaner in both client and server.
6719 These were major changes in both client and server.
6721 * Created many common functions in server to do packet sending.
6722 Previously code were duplicated a lot, this has been removed
6725 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6727 * Rewrote major parts of the ID cache system. Don't know
6728 whether it is better now or not but at least the API is more
6731 * Major rewrite on ID cache stuff on client because of the ID
6732 cache API changes. Added idlist.c to client.
6734 * Also major rewrite on ID cache stuff on server as well.
6735 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6736 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6737 in hand, instead they are all put into the ID cache system now.
6738 All server_idlist_* routines uses ID cache now instead of
6739 traversing its own lists (those lists does not exist anymore).
6740 SilcIDList though still exists. Also, SilcXXXEntry's are
6743 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * Finally made the SKE implementation compliant to the protocol
6746 specification. All mp integers are now binary encoded as
6747 opposed being HEX encoded.
6749 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6752 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6753 functions: silc_[encode/decode]_pem. Also added function
6754 silc_encode_pem_file to PEM encode with newlines ('\n') for
6757 * SILC public keys are now encoded either PEM or binary. Same
6758 option is for private keys as well. By default private keys
6759 are binary encoded and public keys PEM encoded. Silly HEX
6760 encoding were removed.
6762 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6763 function to create fingerprints.
6765 * Fixed a bug in SHA1; does not change the original data anymore.
6767 * Partly implemented INFO command on client and server side.
6768 Fixed CLEAR command. Changes to SERVER command; show current
6769 server(s) when giving command without arguments. Added
6770 VERSION command to client.
6772 * Added check to server that unregistered connections cannot
6773 execute commands (unless it is specificly allowed).
6775 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6777 * Fixed screen refresh.
6779 * Fixed channel joining bug from client. On some circumstances
6780 client tried to join to a channel it had already joined.
6782 * Added public key verification process into client's protocol.c.
6783 The client now verifies the public key from user and saves
6784 it into ~./silc/serverkeys/ directory.
6786 Added into: clientutil.[ch]: silc_client_verify_server_key.
6788 * Changed SKE protocol's silc_ske_initiator_finish function
6789 to accept callback function that verifies the received public
6790 key. Removed old silc_ske_verify_public_key function.
6792 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6795 silc_pkcs_private_key[_data]_set.
6797 * Made the password and public authentication more cleaner in
6798 server's protocol.c.
6800 * Removed historic and obsolete protocol `channel_auth' from
6801 both client and server.
6803 * Removed wrong way of sending command status messages from
6804 server to client in server's command.c. The old way violated
6805 protocol specification.
6807 Changes to silccore/silccommand.[ch]: removed
6808 silc_command_encode_status_payload -> not needed anymore,
6809 changed silc_command_encode_payload_va to accept extra
6810 argument on variable argument list. The argument type must
6811 now be provided to the function. Also, added new function:
6812 silc_command_encode_reply_payload_va which is same as
6813 normal command_encode_payload_va except command status type
6814 is provided as extra argument.
6816 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Added ~./silc directory handling. The directory includes the
6819 public and private keys for the client.
6821 Added silc_client_check_silc_dir, silc_client_create_identifier
6822 and silc_client_load_keys.
6824 * Implemented SILC protocol compliant public key. Added public
6825 and private key saving to and loading from files.
6827 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6828 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6829 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6830 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6831 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6833 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6834 silc_pkcs_load_[public/private]_key.
6836 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Added silc_server_get_route (route.[ch]) to get connection
6839 data for the fastest route for given ID.
6841 * Implemented INVITE command on client and server. The command
6842 were re-defined in the SILC Protocol Specification and the
6843 implementation now complies with the specification.
6845 * Implemented PING command on client and server.
6847 * Implemented NAMES command on client and server. The server side
6848 supports currently only normal server not router server yet.
6849 Some changes to NAMES definition in SILC protocol specification.
6851 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Implemented LEAVE command on client and server.
6855 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6856 again. This change was made to the protocol as well. Server
6857 should not violate the protocol specification anymore.
6859 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6862 was tested. SOCKS4 was not but should work anyway.
