4 nick change. Affected file lib/silcclient/command.c.
5 Fixes the CUMODE command when regaining founder privileges,
6 and a little WHOIS problem.
8 * Fixed silc_net_gethostbyname to correctly call the
9 inet_ntop. Affected file lib/silcutil/silcnet.c.
11 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'

41 * Fixed LIST command reply sending in server. Affected file
44 * Server now sends the kicker's client ID in the KICK notify
45 to the kicked client. Affected file silcd/command.c.
47 * The client library now parses the kickers client ID and
48 UI displays it. Affected files lib/silcclient/client_notify.c
49 and irssi/src/silc/core/silc-channels.c, module-formats.c.
51 * Made all payload parsing function prototypes consistent.
52 They all take now const unsigned char * and uint32 pair as
53 the payload data instead of SilcBuffer. Changes all around
54 the source tree. Other unsigned char* -> const unsigned char*
55 changes around the tree as well.
57 * Optimized SFTP client and server packet sending not to
58 allocate new buffer for each packet but to recycle the
59 first allocated buffer. Affected files are
60 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
62 * Optimized the SFTP client to use SilcList instead of
63 SilcDList for requests, because it is faster. Affected file
64 is lib/silcsftp/sftp_client.c.
66 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
67 into lib/silccore/silcid.[ch].
69 Renamed silcpayload.[ch] into silcargument.[ch].

73 * If client entry is deleted with active key agreement
74 session, abort the session.
76 The silc_client_abort_key_agreement now calls the completion
77 callback with new SILC_KEY_AGREEMENT_ABORTED status.
79 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
82 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
84 * Don't use __restrict in older GCC's. Affected file is
85 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
87 * silc_net_localhost now attempts to reverse lookup the
88 IP/hostname. Affected file lib/silcutil/silcnet.c.
90 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
91 command. It can be used to gain founder privileges at
92 the same time when joining the channel.
94 Defined that the SILC_NOTIFY_TYPE_KICKED send the
95 kicker's client ID as well. Updated protocol specs.
97 Defined that the server must send SILC_COMMAND_IDENTIFY
98 command reply with error status to client who sent
99 private message with invalid client ID.
101 Updated the protocol specification.
103 * Added silc_server_send_command_reply to send any
104 command reply. Affected file silcd/packet_send.[ch].
106 * Added silc_id_payload_encode_data to encode ID payload
107 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
109 * The server now send IDENTIFY command reply with error
110 status if client ID in private message is invalid. Affected
111 file silcd/packet_receive.c.
113 * Save the server key file with server's IP address in
114 the filename instead of hostname. The affected file is
115 irssi/src/silc/core/client_ops.c.
117 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
119 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
122 * Added libtool support for compiling shared objects in
123 lib/silcsim. Affected file configure.in.pre and
124 lib/silcsim/Makefile.am. Original patch by cras.
126 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
128 * Pid file configuration, and server's config file fixes
129 patch by toma. Updated CREDITS file.
131 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
133 * Fixed silc_client_channel_message to not try to decrypt
134 the message twice if it resolved the destination client
135 information. This could cause of dropping one channel
136 message. Affected file lib/silcclient/client_channel.c.
138 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
140 * Added silc_client_run_one into lib/silcclient/silcapi.h and
141 lib/silcclient/client.c. This function is used when the SILC
142 Client is run under some other scheduler, or event loop or
143 main loop. On GUI applications, for example this may be
144 desired to used to run the client under the GUI application's
145 main loop. Typically the GUI application would register an
146 idle task that calls this function multiple times in a second
147 to quickly process the SILC specific data.
149 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
151 * Fixed silc_server_drop() for dropping the supplementary
152 groups as well, this could cause a security hole on some
155 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
157 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

165 file silcd/command.c.
167 * Added INFO command reply handling to the Irssi SILC Client.
168 Affected file irssi/src/silc/core/client_ops.c.
170 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
172 * Fixed the silc_idcache_list_* routines to really support
173 the dynamic list. Fixes a crash. Affected file is
174 lib/silccore/silcidcache.c.
176 * Fixed the LIST command reply to really call LIST command's
177 pending callbacks. Affected file silcd/command_reply.c.
179 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
181 * Update conn->local_entry->nickname after giving NICK
182 command. Affected file lib/silcclient/command.c.
184 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
186 * Added the [pid] option to the silcd configuration file
188 Affected files: serverconfig.[ch] and silcd.c

192 * Save fingerprint in WHOIS command reply in server.
193 Affected file silcd/command_reply.c.
195 * Fixed NICK commands pending callback registration.
196 Affected file lib/silcclient/command.c.
198 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
200 * Use ++server->cmd_ident when sending commands in server,
201 instead of random number. Affected file silcd/command.c.
203 * Fixed GETKEY command reply to call actually GETKEY pending
204 command callbacks. Affected file silcd/command_reply.c.
206 * A bit stricter check for nicknames. Check for same nickname
207 in NICK command also. Affected file silcd/command.c.
209 * Do not call INFO command everytime client ID changes, only
210 during first connecting. Affected file lib/silcclient/client.c.
212 * Set the new nickname only after successful command reply for
213 NICK command is returned by server. Affected file
214 lib/silcclient/command.c.
216 * Remove nicknames from nicklist during server_signoff notify.
217 Should fix /NAMES bit more. The affected file is
218 irssi/src/silc/core/silc-channels.c.
220 * Added `fingerprint' field to the SilcIDListData in the
221 silcd/idlist.h to hold the fingerprint of the client's
224 Send the fingerprint of the client's public key in WHOIS
227 Affected files silcd/command.c, and silcd/idlist.[ch].
229 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
230 create fingerprint from given data.
232 * Show the fingerprint of the client's public key in WHOIS.
233 Affected files irssi/src/module-formats.[ch] and
234 irssi/src/silc/core/client_ops.c.
236 * Format the multiple same nicknames also during JOIN and
237 NICK_CHANGE notifys. Affected file is
238 lib/silcclient/client_notify.c.
240 * Do not print error on screen for invalid private message
241 payload since it can come if someone is sending private
242 messages with wrong key. Affected file
243 lib/silccore/silcprivate.c.
245 * Fixed multiple concurrent /PING crash. Affected file
246 lib/silcclient/command.c.
248 * Changed the wrong ID encoding. All IP addresses must be
249 in MSB first order in encoded format. They were encoded
250 wrong and was in LSB format. Affected files are
251 silcd/serverid.c, lib/silcutil/silcutil.c.
253 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
255 * Call the `connect' client operation through the scheduler
256 in case of error. Affected file lib/silcclient/client.c.
258 * Call the `failure' client operation even if the error
259 occurred locally during a protocol. Affected file is
260 lib/silcclient/protocol.c.
262 * Added support of sending LIST command to router from normal
263 server. This way normal server can get list of all channels
264 in the network too. Fixed the channel list sending in the
265 server too. Affected files are silcd/command.c, and
266 silcd/command_reply.[ch].
268 * Added silc_server_update_channels_by_server and
269 silc_server_remove_channels_by_server. They are used during
270 disconnection of primary router and in backup router protocol.
271 Affected file silcd/server_util.[ch], silcd/server.c and
272 silcd/server_backup.c.
274 * Fixed channel adding to global list in IDENTIFY command
275 reply in server. Affected file silcd/command_reply.c.
277 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
279 * If the incoming packet type is REKEY or REKEY_DONE process
280 that packet always synchronously. Fixes yet another MAC
281 failed error on slow (dialup) connections. Affected file
282 lib/silcclient/client.c and silcd/server.c.
284 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
286 * Call check_version SKE callback for initiator too. Affected
287 file lib/silcske/silcske.c.
289 * Implemented fix for security hole found in the SKE that was
290 fixed in the specification few days back; the initiator's
291 public key is now added to the HASH value computation.
292 Added backwards support for the old way of doing it too, for
293 old clients and old servers. Affected file is
294 lib/silcske/silcske.c.
296 * Enabled mutual authentication by default in SKE. If initiator
297 is not providing mutual authentication the responder will
298 force it. This will provide the proof of posession of the
299 private key for responder. The affected files are
300 lib/silcclient/protocol.c and silcd/protocol.c.
302 * Do not cache anymore the server's public key during SKE.
303 We do mutual authentication so the proof of posession of
304 private key is done, and if the server is authenticated in
305 conn auth protocol with public key we must have the public
306 key already. Affected file silcd/protocol.c.
308 * Added new global debug variable: silc_debug_hexdump. If
309 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
310 file lib/silcutil/silclog.[ch].
312 * Fixed compilation warning due to char * -> const char *.
313 Affected files lib/silcutil/silcnet.h, and
314 lib/silccore/silcauth.[ch].
316 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Fixed CMODE command when new channel key was created. If
319 the creation failed the old key was removed. Next time giving
320 same command would crash the server since the old key was
321 freed already. Affected file silcd/command.c.
323 * Fixed the silc_server_announce_get_channels to not crash
324 on reconnect. Affected file silcd/server.c.
326 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
328 * Added silc_log_set_debug_string function to set a regex
329 string to match for debug output. Only the function names,
330 or filenames matching the given debug string is actually
331 printed. This way it is possible to filter out those debug
332 strings that user is not interested in.
334 Fixed a bug in silc_string_regexify.
336 Affected files lib/silcutil/silclog.[ch], and
337 lib/silcutil/unix/silcunixutil.c.
339 * Changed the -d options in both server and Irssi SILC client
340 to take the debug string as argument. Affected files
341 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
343 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
345 * Added silc_hash_babbleprint to create a Bubble Babble
346 Encoded fingerprint. The encoding is developed by Antti
347 Huima (draft-huima-babble-01.txt), and it creates human
348 readable strings out of binary data. Affected file
349 lib/silccrypt/silchash.[ch].
351 * Print the babble print now in addition of fingerprint as well
352 in Irssi SILC client. Affected files are
353 irssi/src/fe-common/silc/module-formats.[ch],
354 irssi/src/fe-common/silc/core/client_ops.c.
356 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Fixed a security problem found in SKE. The initiator's
359 public key too is now added to the HASH hash value creation
360 which is signed by the responder to create the SIGN value.
361 This will prevent anyone in the middle to lie to the responder
362 about the initiator's public key. If this is done now, the
363 man in the middle will get caught. Updated the protocol
366 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
368 * Better installation directory handling. Configure module
369 paths and other paths automatically to example_silc* files
370 in doc/. A patch by toma.
372 * Fixed compiler warning from MPI library, and from SILC RNG.
375 * Added SILC_SERVER_PID_FILE to define the pid file for server.
376 It can be configured with ./configure. A patch by toma.
378 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
380 * Find correct make to use in prepare-clean. A patch by
381 toma. Affected file prepare-clean.
383 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
385 * Added irssi variables use_auto_addr, auto_bind_ip,
386 auto_bind_port and auto_public_ip.
388 * Changed the interface for silc_client_send_key_agreement
389 in lib/silcclient/silcapi.h
393 irssi/src/silc/core/silc-core.c
395 lib/silcclient/silcapi.h
396 irssi/src/silc/core/silc-channels.c
397 lib/silcclient/client_keyagr.c
400 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
402 * Added silc_pkcs_public_key_compare to compare two
403 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
405 * Check that the client who set the founder mode on the
406 channel is the same client that is giving the founder
407 mode to itself. It is done by comparing the saved public
408 key (it is saved even in the authentication is passphrase).
409 Affected file silcd/command.c.
411 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
413 * Do not process packet for disconnected socket connection.
414 Affected file lib/silccore/silcpacket.c.
416 * Process the DISCONNECT packet through scheduler in the
417 client library. Affected file lib/silcclient/client.c.
419 * Fixed the silc_client_packet_parse to not to increase
420 the packet sequence number if the conn->sock and the
421 current socket connection is not same. This can happen
422 for example during key agreement when the conn includes
423 multiple socket connections (listeners). Affected file
424 lib/silcclient/client.c.
426 * The sender of the file transfer request now provides also
427 the pointer (listener) for the key exchange protocol. If
428 the listener cannot be created then it sends empty key
429 agreement and lets the receiver provide the listener.
431 Added `local_ip' and `local_port' arguments to the
432 silc_client_file_send. If they are provided they are used,
433 if not then it will attempt to find local IP address, if
434 not found or bind fails then the remote client will provide
437 Affected files are lib/silcclient/client_ftp.c and
438 lib/silcclient/silcapi.h.
440 * Extended the FILE SEND command to support defining the
441 local IP and port for key exchange listener. They are
442 optional. Affected file irssi/src/silc/core/silc-servers.c.
444 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
446 * Defined to WHOIS command reply the sending of fingerprint
447 of the client's public key (if the proof of posession of the
448 corresponding private key is verified by the server).
449 Updated to the protocol specification.
451 * Added support of receiving the client's public key's
452 fingerprint in command reply in client library. Affected
453 file is lib/silcclient/command_reply.c, and
454 lib/silcclient/idlist.[ch].
456 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
458 * Do not send over 128 chars long nickname to the server
459 in NICK command. Affected file lib/silcclient/command.c.
461 * Do not send over 256 chars long channel names to the server
462 in JOIN command. Affected file lib/silcclient/command.c.
464 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
466 * Assure that silc_server_close_connection cannot be called
467 twice for same socket context. Affected file is
470 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
472 * Send error message to application if opening file for
473 writing during file transfer fails. Affected file is
474 lib/silcclient/client_ftp.c.
476 Remove all file transfer sessions for a client that we're
477 removing from ID cache.
479 Affected file is lib/silcclient/client_ftp.c.
481 * Fixed silc_net_addr2bin to return correct address. Affected
482 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
484 * Fixed file transfer session removing on signoff notify.
485 Affected file irssi/src/silc/core/silc-servers.c.
487 * Added the SilcClientFileError to be returned in the monitor
488 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
489 Affected file lib/silcclient/silcapi.h.
491 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Fixed a crash in silc_client_ftp_free_sessions and
494 silc_client_ftp_session_free_client. Affected file
495 lib/silcclient/client_ftp.c.
497 * Added `disabled' field in the SilcChannelEntry in the server
498 to indicate if the server entry is disabled. Affected file
499 silcd/idlist.h, silcd/command[_reply].c.
501 * SILC server adds now /var/run/silcd.pid everytime it is
502 started. Affected file silcd/silcd.c.
504 * Added silc_server_packet_send_clients to send a packet to
505 the provided table of client entries. Affected file
506 silcd/packet_send.[ch].
508 * Fixed a crash in client resolving in client_prvmsg.c in
509 client library. Affected file lib/silcclient/client_prvmsg.c.
511 * Do not actually remove the client directly from ID cache
512 during SERVER_SIGNOFF, but invalidate it. This way we
513 preserve the WHOWAS info for the client. Affected file
516 * Fixed SERVER_SIGNOFF notify handling in the server. The
517 server is now able to process incoming SERVER_SIGNOFF notify
518 for a server that it doesn't even know about. It will remove
519 the clients provided in the notify. Affected file
520 silcd/packet_receive.c.
522 * Check for partial packet in data queue after every packet that
523 was found from the queue. Return and wait for more data if
524 there is partial data in queue. Affected file is
525 lib/silccore/silcpacket.c.
527 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
529 * Added SilcClietFileError enum to indicate error in
530 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
531 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
532 Affected files lib/silcclient/silcapi.h and
533 lib/silcclient/client_ftp.c.
535 * Check that newsize in silc_buffer_realloc is larger than
536 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
538 * Added better monitor of file transfers. It now monitors
539 key agreement protocol during the file transfer too. Added
540 error reporting too. Affected files
541 irssi/src/silc/core/silc-servers.c,
542 irssi/src/fe-common/silc/module-formats.[ch].
544 * Wrote a help file for FILE command.
546 * Added silc_rng_global_get_byte_fast to get not-so-secure
547 random data as fast as possible. Random data is read from
548 /dev/urandom if available and from the SILC RNG if not
549 available. It is used in padding generation. Affected file
550 lib/silccrypt/silcrng.[ch].
552 * All packets in client library are now processed synchronously.
553 Optimized packet processing a lot. Affected file
554 lib/silcclient/client.c.
556 * All server connection packets are processing synchronously
557 now in server, to optimize packet processing. Affected file
560 * Include files are installed now only in Toolkit distribution
561 if make install is given. Affected files: all Makefile.am's.
563 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Assure that silc_client_notify_by_server_resolve does not
566 resolve the client information multiple times. If it cannot
567 be found by the first it cannot be found at all. Affected

571 lib/silcclient/command_reply.c.
573 * Removed all references to silc_idlist_get_client from the
574 Irssi SILC client since that call is internal call used by
575 the library. The Irssi SILC client will use now client
576 retrieval functions found in silcapi.h.
578 * Fixed a bug in resolving nickname info before sending
579 private message. It used freed memory. Affected file
580 irssi/src/silc/core/silc-servers.c.

645 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Resolve the client info when received private message or
648 channel message for a client which nickname we don't know.
649 Affected files lib/silcclient/client_prvmsg.c and
650 lib/silcclient/client_channel.c.
652 * Do not crash in /KEY if client is not connected. Affected
653 file irssi/src/silc/core/silc-channels.c.
655 * Added SilcClientStatus field to the SilcClientEntry in the
656 lib/silcclient/idlist.h.
658 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
659 is incomplete and is being resolved, it won't be resolved
662 Make sure also that USERS command reply does not resolve
663 twice information. Affected file is
664 lib/silcclient/command_reply.c.
666 Make sure that silc_client_get_clients_by_list does not
667 resolve twice same information.
669 * Check for valid client->id in the silc_server_free_client_data.
670 Affected file silcd/server.c.
672 * Fixed /GETKEY nick@server not to crash if the server entry

695 * Redefined the SILC packet header to include the padding
696 length. Affected file lib/silccore/silcpacket.[ch].
698 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
699 length for maximum padding up to 128 bytes). Affected
700 file lib/silccore/silcpacket.h.
702 * Removed all backwards support for old 0.5.x MAC thingies.
703 The SILC packet header change makes it impossible to be
704 backwards compatible.
706 * Send the ENDING packet with timeout in the backup resuming
707 protocol. This is to assure that all routers has connected
708 to the primary router. Affected file silcd/server_backup.c.
710 * Changed the RNG to take the first IV from random data. It
711 used to take it from zero actually. Changed the RNG also
712 to use /dev/urandom during session. /dev/random is used
713 in initialization. Affected file lib/silccrypt/silcrng.[ch].
715 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
717 * Changed the SILC packet header to have the first two bytes
718 (the packet length) encrypted. Affected files aroung the
719 code tree, lib/silccore/silcpacket.[ch]. Removed the
720 SilcPacketCheckDecrypt callback. It is not needed anymore
721 since the silc_packet_receive_process will determine now
722 whether the packet is normal or special.
724 * Implemented the unidirectional MAC keys. Affected files
725 lib/silcske/silcske.c, silcd/protocol.c and
726 lib/silcclient/protocol.c.
728 * Implemented the packet sequence number to the MAC computation.
729 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
730 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
731 lib/silcclient/protocol.c.
733 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Allow backup router to announce servers. All servers
736 announced by backup router are added to the global list
737 automatically. Update hte server's socket to our primary
738 router also when backup router announces a server.
739 Affected file silcd/packet_receive.c.
741 * Do not update the client->router in the function
742 silc_server_udpate_clients_by_server if the client is on
743 global list. We might fail to find any specific server
744 for locally connected clients and local cell clients. They
745 should still use the `from' and not `to' as client->router.
746 This fixes backup router resuming protocol. Affected file
749 * Decrease channel statistics count only if the channel
750 deletion worked. Affected files are silcd/server.c and
753 * Added silc_server_update_servers_by_server to update origin
754 of all server entries. Used during backup router protocol.
755 Affected files silcd/server_util.[ch], silcd/server.c. and
756 silcd/backup_router.c.
758 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
759 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
760 silc_hmac_get_hash and silc_hmac_get_name. Affected file
761 lib/silccrypt/silchmac.c.
763 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Assure that router cannot reroute the same channel message
766 to the sender. Affected file silcd/packet_receive.c.
768 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Made better checks that the channel message is not sent
771 to the router it came from. Affected file is
772 silcd/packet_send.c. Fixed memory leak too.

775 only after checking if it is replaced by backup router.
776 Affected file silcd/packet_receive.c.
778 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
780 * Fixed the backup resuming protocol to work in multiple
781 router environment. Affected file silcd/server_backup.c.
783 * Route packet only to one router in the function
784 silc_server_packet_send_to_channel. Affected file is
787 * Fixed silc_server_send_notify_dest to set the broadcast
788 flag. Fixed the silc_server_send_notify_topic to actually
789 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
790 Affected file silcd/packet_send.c.
792 * Changed the SFTP Filesystem interface. Changed the
793 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
794 the filesystem operation function. The SilcSFTPFilesystem
795 is now a context that is allocated by all filesystem allocation
796 functions and it already includes the operations structure
797 and filesystem specific context. It is given as argument
798 now to the silc_sftp_server_start. This made the interface
799 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
800 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
802 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
804 * Changed the backup router adding and getting interfaces
805 in the server. The router that will be replaced by the
806 specified backup router is now sent as argument. Affected
807 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
810 * Added silc_net_addr2bin_ne to return the binary form of
811 the IP address in network byte order. Affected files
812 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
814 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

828 protocol specification.
830 * Removed one redundant channel key generation from normal
831 server during joining procedure. Removed one redundant
832 channel key sending from server to router during joining
833 procedure. Affected file silcd/command.c.
835 * Made minor bugfixes to the backup router resuming protocol.
836 Affected file silcd/server_backup.c, server.c.

841 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
844 * Implemented the backup resuming protocol that is used to
845 resume the primary router position in the cell after the
846 primary router comes back online. Affected files
847 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
848 and silcd/server_util.[ch].

858 * Assure that if outgoing data buffer is pending do not force
859 send any data. Affected file lib/silcclient/client.c.
861 * Implemented the backup router support when the primary router
862 goes down. The servers and routers can now use the backup
863 router as new primary router without loosing connectivity.

867 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
868 in the server to indicate disabled entry. All data read
869 from the connection will be ignored and no data is sent
870 for entry that is disabled. Affected files are
871 silcd/idlist.h, silcd/server.c.
873 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
875 * Created SFTP client and server test programs in the
876 lib/silcsftp/tests directory.
878 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Implemented memory filesystem (virtual filesystem) for
881 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
884 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
886 * Implemented the SFTP (SSH File Transfer Protocol) to the
887 lib/silcsftp. It includes SFTP client and SFTP server
890 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Moved lib/silccore/silcprotocol.[ch] to the
893 lib/silcutil library.
895 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
896 take variable argument list pointer as argument. Affected
897 file lib/silcutil/silcbuffmt.[ch].
899 * Added silc_buffer_set function that is used to set data
900 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
901 Affected file lib/silcutil/silcbuffer.h.
903 * Changed various routines in the core library to use the new
904 silc_buffer_set instead of allocating new buffer only for
907 * Added 64-bit value formatting and unformatting support to the
908 silc_buffer_[un]format routines. Affected file is
909 lib/silcutil/silcbuffmt.[ch].
911 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
912 to includes/bitmove.h.
914 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
916 * Fixed channel user mode saving in client library. Affected
917 file lib/silcclient/command[_reply].c.
919 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
921 * Defined the file transfer to the SILC Protocol. Added
922 new packet type SILC_PACKET_FTP and defined File Transfer
923 Payload. The mandatory file transfer protocol is SFTP
924 (SSH File Transfer Protocol). Affected file in addition
925 of the internet draft is lib/silccore/silcpacket.h.
927 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
928 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
929 is used as part of backup router protocol when the primary
930 router of the cell is back online and wishes to resume
931 the position as primary router.
933 * Redefined the MAC generation keys in the protocol. The
934 same key is not used anymore in both direction. Both
935 direction will now use different keys for sending and
936 receiving. This fixes a potential security flaw. This
937 change causes incompatibilities in the protocol.
939 * Redefined also the MAC computation from the packet.
940 An packet sequence number is now added to the MAC
941 computation. This prevents possible replay attacks against
942 the protocol. This change too causes incompatibilities
945 Added `sequence' field to the SilcPacketContext to hold
946 the current sequence number for the packet.
948 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Added `created' field to the SilcIDListData in the file
951 silcd/idlist.h to indicate the time when the entry was
954 * Added `created' field to the SilcChannelEntry too. Affected
957 * Added `creation_time' aguments to all the announcement functions
958 in the server. If it is provided then only the entries that
959 was created after the provided time frame are actually
960 announced. Affected file silcd/server.[ch].
962 * The protocol says that the Channel ID's IP address must be
963 based on the router's IP address. Added check for this in
964 the silc_server_new_channel when processing incoming New Channel
965 Payload. Affected file silcd/packet_receive.c.
967 * Print out the correct version with --version in SILC client.
968 Affected file irssi/src/silc/core/silc-core.c.
970 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

973 entry always, not just when the command is coming from client.
974 Affected file silcd/command.c.
976 * Added new function silc_server_packet_queue_purge to purge the
977 outgoing data queue to the network. After the function returns
978 it is guaranteed that the outgoing packet queue is empty.
979 Affected file silcd/packet_send.[ch].
981 * Purge the outgoing packet queue in the rekey protocol's final
982 callback to assure that all rekey packets go to the network
983 before quitting the protocol. Affected file silcd/server.c.
985 * Added silc_client_packet_queue_parse as similar function as
986 in server to the client library. The affected file is
987 lib/silcclient/client.c.
989 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Splitted silcd/server.c and created silcd/server_util.[ch]
992 for utility functions.
994 * Added new socket flag SILC_SF_DISABLED to indicate that the
995 connection is open but nothing can be sent to or received from
996 the connection. Affected file lib/silcutil/silsockconn.[ch].
997 The checking for disabled socket is checked in the low level
998 silc_socket_write and silc_socket_read functions.
1000 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Allow only nicknames and channel names that fits into the
1003 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1005 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1007 * When processing JOIN command reply in server check that if
1008 the channel exists in our global list we'll move it the local
1009 list. Affected file silcd/command_reply.c.
1011 * Fixed the check whether client is joined on the channel already
1012 in JOIN command. Affected file lib/silcclient/command.c.
1014 * Fixed the JOIN command reply to check whether the channel
1015 already exists. Affected file lib/silcclient/command_reply.c.
1017 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1019 * Added silc_ske_status_string to map the SKE error numbers
1020 to readable strings. The affected files are
1021 lib/silcske/silcske[_status].[ch].
1023 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1025 * Do not show the private channels on the WHOIS channel list
1026 as it is not allowed by the protocol. The affected file is
1029 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * Assure that the packet length digged from the actual packet
1032 is something sensible in the silc_packet_decrypt_rest_special
1033 in lib/silccrypt/silcpacket.c.
1035 * Free and NULL the allocated pointer in silc_hmac_alloc if
1036 the HMAC allocation fails. The affected file is
1037 lib/silccrypt/silchmac.c.
1039 * Print the selected security properties to the log files in
1040 the server. Affected file silcd/protocol.c.
1042 * Add SKE's reference counter even if calling the completion
1043 callback manually. Otherwise it goes negative, although it
1044 does not cause any problems. The affected file is
1045 lib/silcske/silcske.c.
1047 * Remove the client entry with short timeout after giving the
1048 KILL command. Affected file lib/silcclient/command.c.
1050 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1051 case all found clients are already disconnected (WHOWAS would
1052 found them) in the server. Affected file silcd/command.c.
1054 * Update the last_receive (time of last data received) to be
1055 updated only when received private or channel message so that
1056 the idle time showed in WHOIS makes more sense.
1058 * Added boolean field `valid' in to the SilcClientEntry in the
1059 client library to indicate whether the entry is valid or not.
1060 This fixes the nickname change bug on channel when changing
1061 the nickname to be same than the old (like nick to Nick) the
1062 nickname formatter doesn't set the new nick anymore to Nick@host.
1063 Affected file lib/silcclient/idlist.[ch].
1065 * Now actually fixed the nickname changing on disconnection.
1066 Added new function silc_change_nick to the Irssi SILC Client.
1067 Affected file irssi/src/silc/core/client_ops.c,
1068 irssi/src/silc/core/silc-nicklist.[ch].
1070 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1072 * Check that the public key exists in the GETKEY command before
1073 trying to encode it. Affected file silcd/command.c.
1075 * Print some notifications on received public keys with GETKEY
1076 command in the Irssi SILC Client. Affected files are
1077 irssi/src/fe-common/silc/module-formats.[ch],
1078 irssi/src/silc/core/client_ops.c.
1080 * Use IDENTIFY command to resolve the server information in the
1081 GETKEY command instead of INFO command. Affected file
1082 lib/silcclient/command.c.
1084 * All command reply functions in the client library now calls
1085 the pending command reply callbacks even if an error has
1086 occurred. The server has done this a long time and now it was
1087 time to move the client library to this as well. Now all
1088 errors can be delivered back to the pending command reply
1089 callbacks if necessary. Affected files are
1090 lib/silcclient/command[_reply].[ch].
1092 * Change the nickname on disconnection back to the username
1093 because in reconnect the server will enforce it to it anyway.
1094 Affected file irssi/src/silc/core/silc-servers.c.
1096 * Fixed a config file parsing bug in the Irssi SILC client.
1097 Affected file irssi/src/silc/core/clientconfig.c.
1099 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * When printing the channel mode on JOIN, verify that the
1102 channel key and channel's HMAC are valid. Affected file
1103 irssi/src/silc/core/client_ops.c.
1105 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1108 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1109 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1111 * Removed channel key rekey task deleting from the function
1112 silc_server_save_channel_key. Affected file silcd/server.c.
1113 Added explicit timeout task context instead that is used to
1114 delete the task if we are registering a new task before the
1115 new task has elapsed.
1117 * When channel key rekey occurs the client library now saves
1118 the old channel key for a short period of time (10 seconds) and
1119 is able to use it in case some is still sending channel
1120 messages encrypted with the old key after the rekey. Affected
1121 file lib/silcclient/[idlist.h|client_channel.c].
1123 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Added check to the silc_server_new_id_real to not accept
1126 new ID if it is the sender's own ID. Affected file is
1127 silcd/packet_receive.c.
1129 * Assure that we do not announce ourself or the one we've
1130 sending our announcements when we're router and are announcing
1131 servers to our primary router. Affected file silcd/server.c.
1133 * Fixed silc_server_command_identify_check_client to assemble
1134 correct WHOIS packet. It send corrupted WHOIS packet and
1135 caused problem with router to router connections. Affected
1136 file silcd/command.c.
1138 Fixed also silc_server_command_whois_check the same way
1139 as for the IDENTIFY command.
1141 * Added new SilcIDListStatus to the server in the SilcIDListData
1142 structure. The status now includes the current status of
1143 the entry (like registered, resolved etc.). Affected file
1144 silcd/idlist.[ch]. Defined a bunch of different status types
1145 as well. This replaced the old boolean registered field as well.
1147 Added resolve_cmd_ident field to the SilcClientEntry structure
1148 too so that if the entry is for example being resolved so
1149 another command may attach to the same pending command reply
1150 without requiring to resolve the same entry again. This concept
1151 should optimize the WHOIS and the IDENTIFY resolving under
1152 heavy load by taking away unnecessary resolving for entries
1153 that are being resolved already.
1155 Added support for adding multiple pending commands for one
1156 command idenfier. Affected file silcd/command[_reply].[ch].
1158 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1159 before deleting the data. Otherwise the hash table will have
1160 freed data in comparison functions. Affected file is
1161 silcd/command_reply.c.
1163 * Fixed silc_idlist_replace_client_id to add the new entry to
1164 the cache with NULL nickname. Otherwise there will be invalid
1165 memory as the nickname after the nickname is freed. Affected
1166 file silcd/packet_receive.c.
1168 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1169 saved into wrong slots because the previous number of entries
1170 was not taken into account. Affected file silcd/idlist.c.
1171 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1173 * If we are router and we receive JOIN notify to a channel that
1174 does not have any users then notified client is marked as the
1175 channel founder, as it is it. The affected file is
1176 silcd/packet_receive.c
1178 * Added to the extended hash table API's table_del_*ext functions
1179 the destructor as argument too, so that the caller can decide
1180 which destructor to use or whether to use destructor at all.
1181 Affected file lib/silcutil/silchashtable.[ch].
1183 * Fixed ID Cache purging. It actually deleted the entries from
1184 the hash table after the data was freed. The hash table ended
1185 up comparing freed memory. The affected file is
1186 lib/silccore/silcidcache.c.
1188 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1190 * Fixed Irssi SILC client's KILL command's HELP syntax.
1192 * The USERS command now resolves the detailed user information
1193 if the userinfo field is missing. Affected file is
1194 lib/silcclient/command_reply.c.
1196 * Do not print error in silc_file_read if the read file does
1197 not exist. Just silently return NULL. Affected file is
1198 lib/silcutil/silcutil.c.
1200 * Fixed the silc_log_output to not wine about NULL filename
1201 and to not create some bogus " " filename. Affected file is
1202 lib/silcutil/silclog.c.
1204 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Fixed various printing bugs on the user interface in the
1207 Irssi SILC Client. Minor changes that were forgotten from
1210 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Fixed the configure.in.pre and the compilation and distribution
1213 environment to support the new autoconf 2.52. That version is
1214 now required to compile the CVS trunk.
1216 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1218 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1219 to generally parse user@fqdn format strings. Affected file
1220 lib/silcutil/silcutil.c.
1222 * Added nickname_format and nickname_force_format fields to the
1223 SilcClientParams structure. The first one defines the format
1224 for the nicknames that the library will enforce if the receives
1225 multiple same nicknames. The second one is boolean value and
1226 can be used to force the library to always enforce the format
1227 to the nicknames regardles whether there are multiple nicknames
1228 or not. This configurable formatting was employed to flexibly
1229 support accessing multiple nicknames from the user interface.
1230 The userinterface can now set the nicknames to what ever format
1231 they prefer. Affected file lib/silcclient/silcapi.h.
1233 Added function silc_client_nickname_format to the file
1234 lib/silcclient/idlist.c. It performs the nickname formatting.
1236 Added new field `hostname´ to the SilcClientEntry context.
1237 It holds the hostname of the client. Affected file is
1238 lib/silcclient/idlist.h.
1240 * Irssi SILC Client sets the nicknames in nick@hostn format.
1241 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1242 irssi/src/silc/core/silc-core.c.
1244 The WHOIS printing now also shows both the real nickname and
1245 the formatted nickname so that user knows how to access the
1246 user if there are multiple same nicknames cached. Affected
1247 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1248 printing formatting too to take the hostname now as a separate
1249 argument. The Affected file is
1250 irssi/src/fe-common/silc/modules-formats.[ch].
1252 * Changed the silc_client_get_clients_local to accept the formatted
1253 nickname as argument. It accepts the real nickname too but the
1254 formatted nickname can be used to find the true entry from
1255 multiple entries. Affected file lib/silcclient/silcapi.h and
1256 lib/silcclient/idlist.c.
1258 * Added nickname_format_parse field to the SilcClientParams.
1259 It is a callback function provided by the application to parse
1260 the nickname out of the formatted nickname string. The library
1261 calls it to get the nickname from the formatted string. Since
1262 the application generally knows better the format of the nickname
1263 string it parses it instead of the library, even though library
1264 encodes the formatted string. If the callback function is not
1265 provided then the library will use the string as is. The
1266 affected file is lib/silcclient/silcapi.h.
1268 * All the nickname strings passed to the client library in
1269 commands are now expected to be formatted nickname strings.
1270 If the command does not support the formatted nickname string
1271 it will assume that the sent string is the actual nickname.
1272 Affected file lib/silcclient/command.c.
1274 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1276 * Added public key authentication support to OPER and SILCOPER
1277 commands in the client library. Affected file is
1278 lib/silcclient/command.c.
1280 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Changed the get_auth_methdod client operation to be asynchronous.
1283 It can be async if the application resolves the authentication
1284 method from the server during the negotiation. Added new
1285 SilcGetAuthMeth completion callback that the application will
1286 call after resolving the authentication method.
1288 Added function silc_client_request_authentication_method that
1289 the application can use to resolve the authentication method
1290 from the server. Added also SilcConnectionAuthRequest callback
1291 that the library will call after the server has replied. The
1292 application can call this function if it does not know the
1293 current authentication method.
1295 Affected files are lib/silcclient/client.c and
1296 lib/silcclient/silcapi.h.
1298 * The Irssi SILC client now automatically resolves the authentication
1299 method incase any configuration information is not present (and
1300 currently there never is). The affected file is
1301 irssi/src/silc/core/client_ops.c.
1303 * Fixed public key authentication from the client library.
1304 Affected file lib/silcclient/protocol.c. Changed also the
1305 protocol specification about the public key authentication in
1306 the connection authentication protocol. The actual data to be
1307 signed is now computed with a hash function before signing.
1309 * Fixed the public key authentication from the server as well.
1310 Affected file silcd/protocol.c.
1312 * Removed the mlock()'s from the memory allocation routines.
1313 Affected file lib/silcutil/silcmemory.c. The ./configure does
1314 not check anymore for the mlock(). Affected file is
1317 * Fixed USERS command in server to allow the execution of the
1318 command for private and secret channels if the client sending
1319 the command is on the channel. Affected file silcd/command.c.
1321 * Fixed silc_client_get_clients_local to return the clients
1322 count correctly. It could return wrong value. Affected file
1323 lib/silcclient/idlist.c.
1325 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1328 types. The assembler optimizations seemed not to like 64-bit
1329 data types. The assmebler optimizations thus are now enabled
1330 also for BSD systems as opposed to only enable them for Linux.
1332 * Do not check for threads at all on BSD systems. Affected
1333 file configure.in.pre.
1335 * Removed -n and -h options from the Irssi SILC Client since
1336 they are not used in silc.
1338 * Fixed the prime generation to assure that the first digit
1339 of the generated random number is not zero since our conversion
1340 routines does not like number strings that starts with zero
1341 digit. If zero digit is seen the random number is regenerated.
1342 This caused some corrupted RSA keys when the zero first digit
1343 was met. Affected file lib/silcmath/silcprimegen.c.
1345 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Fixed WIN32 configuration in the ./configure script.
1348 Fixed to include xti.h on environments that has it.
1349 Patches by Carsten Ilchmann and andrew.
1351 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1353 * Changed the silc_id_create_client_id to be collision
1354 resistant. It is now assured that there cannot be created
1355 two same client ID's. I suspect that some weird bugs in
1356 the server were actually caused by duplicate Client IDs.
1357 Affected file silcd/serverid.[ch]. A router receiving
1358 new ID now also assures and informs the sending server
1359 if the ID caused collision.
1361 * Changed the silc_id_create_channel_id to also assure that
1362 there are no collisions.
1364 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Statement about ignoring the Mutual Authentication flag when
1367 performing rekey with PFS was a bit misleading. It is ignored
1368 if it was set in the initial negotiation, it cannot be even
1369 set in the rekey. Fixed in the ke-auth draft. Started the
1370 new versions of the protocol drafts in the doc/.
1372 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Fixed a bug in silc_client_command_identify_save when saving
1375 new channel information. The channel name was no duplicated
1376 and caused crash on exit. Affected file is
1377 lib/silcclient/command_reply.c.
1379 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Fixed the getkey command handling in the server. Send just
1382 empty OK reply to the sender if the key could not be fetched
1383 (but everything else was ok, like the key just was not available).
1384 Changed the public key parameter to optional in the protocol
1385 specs so that empty OK reply can be sent. Affected file
1388 Added a message to Irssi SILC client to tell to user if the
1389 server did not return a public key.
1391 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Fixed a channel key regeneration bug. It registered new
1394 timeout tasks exponentially until all system resources were
1395 used. Affected file silcd/server.c.
1397 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1399 * Added the SILC Document generator to the scripts/silcdoc.
1400 It can be used to generate the Toolkit Reference Manual out
1401 of the source tree. Internally it will also use the RoboDoc
1402 generator now imported in util/robodoc.
1404 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1406 * Added couple of return's in rekey protocol if error orccurred
1407 during the protocol. The execution must be terminated.
1408 Affected file silcd/protocol.c. Also, terminate the protocol
1409 always with timeout.
1411 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * The client's Client ID was created initally from the wrong
1414 nickname (it could have been in format nick@host) in the
1415 silc_server_new_client. Affected file silcd/packet_receive.c
1417 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Added some SILC_LOG_ERROR's to various error conditions
1420 if client could not be added to ID cache. Affected files
1421 silcd/packet_receive.c and silcd/server.c.
1423 * When client's sock->user_data is freed, NULL also the
1424 client->router and client->connection pointers. Added check
1425 for these pointers being NULL to various places around the
1426 code. Affected file silcd/server.c.
1428 * Added client->data.registered == TRUE checks to various
1429 places around the code to assure that unregistered client's
1430 are not handled when it is not allowed. Affected file
1433 * Added `bool registered' fields to all
1434 silc_idlist_[server|client]_get_* routines to indicate whether
1435 the fetched client needs to be registered or not. Affected
1436 file silcd/idlist.[ch].
1438 * Add your own entry as registered to the ID cache in the
1439 server. Affected file server.c.
1441 * Fixed a bug in silc_server_new_server. The SilcServer was
1442 set as the new server's context instead of SilcServerEntry.
1443 This naturally caused some weird bugs.
1445 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1447 * Do not delete the channel rekey task when adding it
1448 for in silc_server_create_channel_key.
1450 * Changed the silc_server_create_channel_key to return
1451 TRUE or FALSE to indicate the success of the channel key
1454 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Fixed MSVC++ project files and added missing files to
1457 Makefiles under win32/.
1459 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Do not add TCP_NODELAY flag if the operating system
1462 does not have it defined. Affected files are
1463 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1465 * Fixed buffer overflow from Irssi SILC Client. Affected
1466 file irssi/src/fe-common/core/themes.c.
1468 * Fixed double free in client library in the file
1469 lib/silcclient/client.c when disconnecting from server.
1471 * Applied double free patch from cras to Irssi SILC client.
1472 Affected files irssi/src/core/[modules/expandos].c
1474 * Fixed the disconnection handling to Irssi SILC Client.
1475 The application must call silc_client_close_connection
1476 in ops->connect client operation in case of failure of
1477 the connection. Affected file is
1478 irssi/src/silc/core/client_ops.c.
1480 * Do not set sock->protocol to NULL in the function
1481 silc_client_close_connection after executing the protocol's
1482 final callback since the sock might not be valid anymore.
1483 Affected file lib/silcclient/client.c.
1485 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1487 * Do not enable SILC_THREADS if the linking with libpthread
1488 did not happen. Affected file configure.in.pre.
1490 * Added notion to protocol specification that server must
1491 verify the sent authentication payload with CMODE when
1492 setting the channel founder key. Implemented it to the
1493 server. Affected file silcd/command.c.
1495 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Added _EXTRA_DIST SILC distribution variable to the
1498 distributions file. It is used to conditionally add extra
1499 files or directories to the specific distribution. Affected
1500 files ./prepare, Makefile.am.pre and distributions.
1502 Removed the `_' from the start of the distribution names.
1505 * Added README.WIN32 for instructions to compile the Toolkit
1508 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Fixed a double free in disconnection in the server. Affected
1511 file is silcd/server.c.
1513 * Fixed the lib/silcske/groups.c to work now also with GMP
1514 MP library. The string conversion did not work when using
1515 specific base and the base is indicated in the string as well.
1517 * Created win32/ directory which now includes MSVC++ specific
1518 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1519 It will appear only in the toolkit distribution
1521 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Changed the key material distribution function in case when
1524 the hash output is too short. The data is now concatenated
1525 a bit differently than it used to. Made the change to the
1526 SKE protocol specification.
1528 * Added better GMP detection to configure.in.pre. A patch
1531 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1533 * Fixed a minor bug in SKE that might cause some problem on
1534 some platforms. Affected file lib/silcske/silcske.c.
1536 * Added the cookie checking for initiator in the SKE. It checks
1537 that the responder returns the sent cookie unmodified. The
1538 affected file is lib/silcske/silcske.c. Added new SKE
1539 error type INVALID_COOKIE that can be sent during the
1540 negotiation. Fixed some memory leaks as well.
1542 * Added the "invalid cookie" error message to Irssi SILC client's
1545 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Added `task_max' field to the SilcClientParams to indicate
1548 the maximum tasks the scheduler can handle. If set to zero,
1549 default values are used. Affected file lib/silcclient/silcapi.h.
1551 * Fixed memory leaks in silc_client_close_connection. Affected
1552 file lib/silcclient/client.c.
1554 * Added silc_client_del_client_entry to client library to free
1555 all memory of given client entry. Affected file is
1556 lib/silcclient/idlist.[ch].
1558 * Added new functions silc_client_del_channel and
1559 silc_client_del_server to delete channel and server entries.
1560 Affected file lib/silcclient/[silcapi.h/idlist.c].
1562 * Removed silc_client_del_client_by_id from silcapi.h.
1564 * Fixed the INFO command to return the server's own info
1565 correctly when querying by Server ID. Affected file is
1568 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1570 * Removed the non-blocking settings in WIN32 code in the
1571 silc_sock_[read/write] and added SleepEx instead. Affected
1572 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1573 of input data is now checked with FIONREAD and ioctlsocket.
1575 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * Call silc_schedule_task_del_by_context in the
1578 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1579 Affected file lib/silccore/silcprotocol.c.
1581 * Call silc_protocol_cancel for active protocols in the
1582 silc_server_close_connection if the funtion
1583 silc_server_free_sock_user_data has not been called.
1584 Affected file silcd/server.c.
1586 * Generic tasks cannot be deleted using the del_by_fd
1587 task deleting function since generic tasks does not match
1588 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1590 * Added a notion to SILCOPER help file that the SILCOPER works
1591 only on router server, not on normal server.
1593 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Added for WIN32 support for the new scheduler as well.
1596 Affected file lib/silcutil/win32/silcwin32schedule.c.
1598 * Fixed the SHA1 implementation to work on various platforms.
1600 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1602 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1603 API. It is part of the scheduler now. Everything else is
1604 as previously but some functions has changed their names.
1605 Checkout the lib/silcutil/silcschedule.h for the interface.
1606 Updated all applications to use the new interface. Affected
1607 files are lib/silcutil/silcschedule.[ch].
1609 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Found a bug in the SKE implementation. The HASH value,
1612 specified by the protocol, was not computed correctly. The
1613 public key of the responder was not added to the computation
1614 even though it is mandatory. Affected file lib/silcske/silcske.c.
1615 This unfortunately causes incompatibilities with older
1616 clients and servers.
1618 * Added WIN32 specific network init and uninit functions:
1619 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1620 the Winsock2. Affected file lib/silcutil/silcnet.h and
1621 lib/silcutil/win32/silcwin32net.c.
1623 * Set the socket always to nonblocking mode on WIN32 after
1624 reading data or writing data. Affected file is
1625 lib/silcutil/win32/silcwin32sockconn.c.
1627 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1629 * Fixed various compilation problems under WIN32. Affected
1630 files lib/silcutil/win32/silcwin32thread.c and
1631 lib/silcutil/win32/silcwin32schedule.c.
1633 * Removed all _internal.h #includes from public header
1634 files. Internal headers must never be included from
1637 Removed also the lib/silcske/payload_internal.h file.
1639 * All include files that may be needed (public and some others
1640 included by the public headers) by application developers are
1641 now copied to the ./includes directory. It does not copy any
1642 internal headers. Affected file Makefile.defines.pre and all
1643 Makefile.am's under lib/ and subdirs.
1645 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Do not change the ~/.silc directory's permissions automatically.
1648 Affected file irssi/src/silc/core/clientutil.c.
1650 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1652 * Do not cancel the protocol in silc_server_close_connection
1653 it might cause recursion. Now cancelled in the function
1654 silc_server_free_sock_user_data. Affected file silcd/server.c.
1656 * Fixed the silc_server_remove_clients_by_server to regenerate
1657 the channel keys correctly finally. Added also new function
1658 silc_server_remove_clients_channels to actually do it.
1659 Affected file silcd/server.c.
1661 * Fixed the silc_server_new_channel to not crash by giving
1662 wrong router to the new channel. Affected file is
1663 silcd/packet_receive.c.
1665 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1667 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1668 which is given as argument to the silc_client_alloc now.
1669 It can be used to configure the client and set various parameters
1670 that affect the function of the client.
1672 * The USERS command in server did not check whether the channel
1673 is private or secret. Affected file silcd/command.c.
1675 * Added new argument to the USERS command in protocol specification.
1676 The USERS command now can take the channel name as argument
1677 as well. Added support for this in client and server and
1678 updated the protocol specs.
1680 * Completed the GETKEY command in client. It can be now used
1681 to fetch also servers public key not only some clients.
1682 Affected files lib/silcclient/command[_reply].c.
1684 * Added silc_client_get_server to return server entry by the
1685 server name. Affected files lib/silcclient/silcapi.h and
1688 * Redefined the IDENTIFY command in protocol specification to be
1689 more generic. It now can be used to query information about
1690 any entity in the SILC Network, including clients, servers and
1691 channels. The query may be based either the entity's name
1692 or the ID. Added support for this in both client and server.
1694 Affected files silcd/command.c and lib/silcclient/command.c
1695 and command_reply.c.
1697 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1698 the _from_client and _from_server functions. Affected file
1701 * Added silc_client_get_channel_by_id_resolve to the file
1702 lib/silcclient/silcapi.h to resolve channel information by
1703 its ID. Added also silc_client_get_channel_by_id that
1704 does not resolve it from the server.
1706 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Added SilcServerEntry context into the client library
1709 to represent one server. The INFO command now allocates
1710 these to save the resolved server info. For now on the
1711 client library will also keep information about servers,
1712 connected and resolved with INFO.
1714 The INFO command now allocates the SilcServerEntry context
1715 and saves the server info there. The COMMAND_REPLY in
1716 the INFO now returns the parameters to application in
1717 same order as defined in the protocol specification.
1719 The entries are cached in the client->server_cache.
1721 * The INFO command is now issued after received the Client ID
1722 from the server. Affected file lib/silcclient/client.c.
1724 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1725 to the application as the mode changer might be server.
1726 It is guaranteed that NULL is not returned anymore to the
1727 application. Affected file lib/silcclient/client_notify.c.
1729 The ID Type is now also passed to the application so that
1730 it can check whether the returned entry is SilcClientEntry
1733 Added new function silc_client_get_server_by_id to return
1734 the server entry by ID. Affected files are the
1735 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1737 * Do not create the channel in the Irssi SILC Client when issuing
1738 the JOIN command but when received the sucessful JOIN command
1739 reply. Otherwise the channel might get created even though we
1740 could not join it. The Affected file is
1741 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1743 * Fixed a channel joining bug in router. The router must also
1744 check the channel modes, invite and ban lists etc. when serving
1745 the JOIN command sent by normal server. Affected file is
1746 silcd/command.c. The router now resolves the client's
1747 information from the server who sent the JOIN command if it
1748 does not know it, and processes the JOIN command only after
1751 * Changed the SilcCommandCb to take new argument; void *context2.
1752 Affected file lib/silccore/silccommand.h
1754 The second argument in the command callbacks in the server now
1755 includes the SilcServerCommandReplyContext if the command was
1756 called as pending command callback from the command reply.
1757 Otherwise it is NULL. When called as pending the status of the
1758 command reply will be checked and if it was erronous the
1759 error will be sent to the original sender of the command.
1760 This way the client always receives the error messages even
1761 though the server was actually the one who received the error
1762 when it resent the command to router, for example. Affected
1763 files silcd/command[_reply].[ch].
1765 * Fixed sending WHOWAS command's error message to client if
1766 the requested client could not be found. It was missing.
1769 * Changed the CMODE and CUMODE commands reply arguments in the
1770 protocol specification. The Channel ID is now sent in both
1771 of the commands to identify the channel. Implemented this
1772 new feature to the client and server. Affected files
1773 lib/silcclient/command_reply.c and silcd/command.c.
1775 * Made better checks for invite and ban lists in the JOIN
1776 command in server. Affected file silcd/command.c.
1778 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1780 * The server now performs the incoming host IP/DNS lookup
1781 using the silc_socket_host_lookup and thus does not block
1782 the server anymore. Affected file silcd/server.c.
1784 * Completed the multi-thread support for SILC Scheduler in
1785 the lib/silcutil/silcschedule.c.
1787 * Fixed the configure.in.pre to detect the pthread correctly
1790 * Fixed a deadlock in silc_task_queue_wakeup in the file
1791 lib/silcutil/silctask.c.
1793 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Added new function silc_schedule_wakeup that is used in
1796 multi-threaded environment to wakeup the main thread's
1797 schduler. It needs to be used when a thread adds a new task
1798 or removes a task from task queues. After waking up, the
1799 scheduler will detect the task queue changes. If threads
1800 support is not compiled in this function has no effect.
1801 Implemented the wakeup mechanism to both Unix and WIN32
1802 systems. Affected files are lib/silcutil/silcschedule.[ch],
1803 lib/silcutil/unix/silcunixschedule.c and the
1804 lib/silcutil/win32/silcwin32schedule.c.
1806 * Added new function silc_task_queue_wakeup to wakeup the
1807 scheduler by the specified task queue. Affected file
1808 lib/silcutil/silctask.[ch].
1810 * The silc_socket_host_lookup_start now wakes up the scheduler
1811 after adding the timeout task. Affected file is
1812 lib/silcutil/silcsockconn.c.
1814 * The silc_socket_host_lookup is synchronous now if the threads
1815 support is not compiled in. However, the callback is still
1816 called asyncronously through the scheduler, anyway. Affected
1817 file lib/silcutil/silcsockconn.c.
1819 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * Added new function silc_socket_host_lookup to perform
1822 asynchronous IP and FQDN lookups for the socket connection.
1823 Affected files lib/silcutil/silcsockconn.[ch].
1825 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1827 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1828 that may or may not compile the mutex support in.
1830 Changed the silc_mutex_alloc interface. It allocates the
1831 mutex now to the sent pointer and returns TRUE or FALSE.
1833 Affected file lib/silcutil/silcmutex.h.
1835 * Wrote the SILC Task Queue interface to support multi-threads.
1836 Affected file lib/silcutil/silctask.[ch].
1838 * Wrote the SILC Scheduler to support multi-threads. Affected
1839 file lib/silcutil/silcschedule.c.
1841 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1844 in lib/silcutil/win32/.
1846 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Defined SILC Mutex API and SILC Thread API and implemented
1849 them for Unix. Affected files are
1850 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1851 lib/silcutil/unix/silcunixmutex.c and
1852 lib/silcutil/unix/silcunixthread.c.
1854 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed the silc_server_remove_clients_by_server's channel
1857 key re-generation. The hash table handling was incorrect
1858 and would not work with many channels. Affected file is
1861 * Fixed some memory leaks around the server code.
1863 * Rewrote the silc_server_get_users_on_channel to support IPv6
1864 based Client ID's. Affected file silcd/server.c.
1866 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1867 specification. However, a separate document must be written
1868 to define the detailed signing procedure and the payload
1869 associated with the flag. Defined the flag to the
1870 lib/silccore/silcchannel.h as well.
1872 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Changed the dynamic tables to static size tables in the
1875 lib/silccrypt/silchmac.c.
1877 * Removed GCC dependencies from the code. A patch by cras.
1879 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Do not show the error "Error receiving packet bla bla"
1882 in server if it really was not an error (-2 means that reading
1883 is pending). Affected file silcd/server.c.
1885 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Fixed a possible crash in silc_server_remove_clients_by_server
1888 in silcd/server.c. Fixed there also some memory leaks.
1890 * Fixed the silc_idlist_replace_client_id. It could replace
1891 wrong key in the hash table. Affected file silcd/idlist.c.
1893 * Do not check whether there are global users on the channel
1894 if the channel->global_users is FALSE. Affected functions
1895 silc_server_remove_from_one_channel and
1896 silc_server_remove_from_channels in silcd/server.c. Also,
1897 do not check if the removed client is local as we can be
1898 sure that global client was not removed from the channel
1899 and checking for global users is not needed.
1901 * The silc_server_remove_clients_by_server now re-generates
1902 the channel keys correctly for those channels that had
1903 clients removed from them. Affected file silcd/server.c.
1905 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Found the reason of random crashes in the server. We weren't
1908 ignoring the SIGPIPE signal (which can be sent in write())
1909 and it crashed the server. Affected file silcd/silcd.c.
1911 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1913 * Assure that sock->user_data is not NULL in the function
1914 silc_server_packet_send in silcd/packet_send.c.
1916 * Disconnect the remote connection if it could not be added
1917 to any ID lists in the server. The affected file is
1920 * Check in silc_server_packet_send[_real/dest] that the
1921 socket is not disconnecting and ignore the data if it is.
1922 Affected file silcd/packet_send.c.
1924 * Define inline to __inline on native WIN32 compilation.
1925 Affected file includes/silcwin32.h.
1927 * Added some explicit type casts for inline code since MSVC
1928 require them. Affected files lib/silcutil/silcbuffer.h,
1929 lib/trq/silcdlist.h and lib/trq/silclist.h.
1931 * Print warning in log files from now on if the packet
1932 decryption fails. Affected file silcd/server.c.
1934 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Changed the `say' client operation's interface to accept
1937 new `type' argument to indicate the type of the message sent
1938 by the library. The application may filter the library's
1939 messages according the type. The affected file is the
1940 lib/silcclient/silcapi.h.
1942 * Added two new functions to lib/silcclient/silcapi.h:
1943 silc_client_del_client and silc_client_del_client_by_id.
1944 Affected file lib/silcclient/idlist.c.
1946 * Moved the clientincludes.h from includes/ to silc/ and
1947 serverincludes.h from includes/ to silcd/.
1949 * The modes for the CMODE and CUMODE are now passed as
1950 uint32 for application with COMMAND_REPLY. The affected
1951 file is lib/silcclient/command_reply.c.
1953 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1955 * /WHOIS without arguments shows client's own information.
1956 Affected file lib/silcclient/command.c.
1958 * Changed PING to not accept any arguments. The specs
1959 says that client can ping only the connected server so
1960 requiring an argument is not needed. Affected file is
1961 lib/silcclient/command.c.
1963 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Fixed a fatal bug in private message sending and reception
1966 encryption and decryption when using private message keys.
1967 The implementation was incorrect and did not follow the
1968 specification. It causd that some of the message were
1969 lost since it did not use the sending and receiving keys
1970 as the protocol suggests. This has been fixed and will cause
1971 incompatibilities with older clients when sending private
1972 message encrypted with private message keys. Affected files
1973 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1974 and various other in Irssi SILC Client.
1976 Added `responder' boolean argument to the functions
1977 silc_client_add_private_message_key[_ske] to indicate when
1978 the key is added as responder or initiator of the key
1981 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1983 * Removed the silc_ske_check_version function and created
1984 a SilcSKECheckVersion callback. Added also a function
1985 silc_ske_set_callbacks that is now used to set all SKE
1986 callbacks. The callback functions are not given to
1987 the SKE functions anymore, but this function is used to
1990 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1992 * Added `silc_version' argument to the silc_client_alloc
1993 to define the version of the application for the library.
1994 The library will use the version string to compare it
1995 against the remote host's (usually a server) version
1996 string. Affected file lib/silcclient/silcapi.h
1998 * Added the KE protocol context to Key Agreement context
1999 in client library so that we can abort the SKE if it
2000 is in process when we get timeout. Affected file is
2001 lib/silcclient/client_keyagr.c.
2003 * Do not resolve the client ID forever if it returns in the
2004 first time that such client does not exist. This was done
2005 for example with private message. Affected file is
2006 lib/silcclient/client_prvmsg.c.
2008 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Do not add regex.h for WIN32. The affected file
2011 includes/silcincludes.h.
2013 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2014 not work yet 100%. It generates the DLL's automatically
2015 when compiling with --with-win32 under cygwin.
2017 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2019 * lib/contrib/regex.c is not compiled on WIN32.
2021 * Added silc_net_get_socket_opt function to the
2022 lib/silcutil/silcnet.h.
2024 * Added includes/silcwin32.h for WIN32 specific includes
2027 * Do not use ptime structure or any of the posix process
2028 functions on WIN32 in lib/silccrypt/silrng.c.
2030 * Added silc_gettimeofday to provide generic function
2031 for struct timeval on all platforms. Added the function
2032 to lib/silcutil/silcutil.h.
2034 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2036 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2037 library as they clearly belong there. As a plus side we
2038 can make the actual socket connection routines platform
2041 Added also new generic function silc_socket_read and
2042 silc_socket_write (that used to be silc_packet_[read/write].
2043 The implementation of these are platform specific.
2045 * Added WIN32 specific routines of silc_socket_[read/write]
2046 to lib/silcutil/win32/silcwin32sockconn.c.
2048 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2050 * Added preliminary support for native WIN32 compilation under
2051 cygwin (using the -mno-cygwin option for GCC) to the
2052 ./configure.in.pre. The --with-win32 now prepares the
2053 compilation for native WIN32.
2055 * Rewrote the SILC Scheduler interface in the file
2056 lib/silcutil/silcschedule.h. The scheduler is now context
2057 based and does not have anymore any global static scheduler.
2058 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2059 and created lib/silcutil/win32 directory for WIN32 based
2062 * Added Unix specific network routines to the
2063 lib/silcutil/unix/silcunixnet.c and the old
2064 lib/silcutil/silcnet.c includes now only generic routines.
2066 Added WIN32 specific network routines to the
2067 lib/silcutil/win32/silcwin32net.c.
2069 * Added Unix specific utility functions from the
2070 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2072 * Added WIN32 SILC Scheduler to the file
2073 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2076 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Do not handle JOIN notify in the server if the target client
2079 is not registered (idata->registered == FALSE). The affected
2080 file is silcd/packet_receive.c.
2082 * Update the nickrec->founder in event_cumode in the Irssi SILC
2083 client. Affected file irssi/src/silc/core/silc-channels.c.
2085 * Fixed the CUMODE_CHANGE notify handling in the server when
2086 server and router are announcing their clients on channels.
2087 Now the mode changes are saved and notified correctly. The
2088 affected file is /silcd/packet_receive.c.
2090 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2091 They really did not replace the cache entry in the ID Cache.
2092 Now they do that. Affected file silcd/idlist.c.
2094 * Fixed the KICK notify handling in the Irssi SILC client to
2095 update the channel records so that the kicked client does not
2096 appear to be on the channel. The affected file is
2097 irssi/src/silc/core/silc-channels.c.
2099 * Always update the conn->current_channel when executing command
2100 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2102 * Fixed the KILL notify handling in Irssi SILC client to remove
2103 the killed client on all channels.
2105 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Fixed the silc_parse_command_line to remove extra spaces
2108 from the start and end of the arguments. Affected file is
2109 lib/silcutil/silcutil.c.
2111 * Cancel and free any active protocol in the function
2112 silc_server_close_connection. Affected file silcd/server.c.
2114 * Cancel and free any active protocol in the function
2115 silc_client_close_connction. Affected file is
2116 lib/silcclient/client.c.
2118 * Do not execute the KILL command for clients that are in
2119 history (ie. they are not in the network). Affected file is
2122 * Fixed KILL notify handling, client does not crash anymore.
2123 Affected file irssi/src/silc/core/silc-channels.c.
2125 * Reduced the default packet buffer size from 2048 to 1024 in
2126 lib/silccore/silcpacket.c.
2128 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2129 counter to the SKE context that is incresed when the SKE library
2130 performs async operation outside the library. If the outside
2131 process frees the SKE context and FREED status will be set
2132 and the library will detect after the sync operation that the
2133 libary is freed. The affected files are
2134 lib/silcske/silcske[_status].[ch].
2136 * Resolve the client entry information in the function
2137 silc_client_channel_message to assure that NULL pointer is not
2138 passed as client entry to the application. */
2140 * Fixed the task timeout calculation to assure that there is
2141 never negative timeouts. The affected file is
2142 lib/silcutil/silcschedule.c.
2144 * Fixed the channel user mode notification sending in server.
2145 It was sent point-to-point to the router (or to server by router)
2146 but it needs to be destined to a channel. The routines now
2147 supports sending the channel user mode notifys to the channels
2148 when announcing clients and channels. Affected files are
2149 silcd/server.c and silcd/packet_receive.c.
2151 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2152 It did not actually replace the old channel entry in the cache.
2153 Affected file lib/silcclient/client_notify.c.
2155 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Fixed a possible crash in silc_packet_send_prepare. It now
2158 assures always that there is enough space in the buffer and
2159 at the tail area of the buffer (for MAC).
2161 Fixed the inbound buffer reallocation in silc_packet_read.
2162 It was old code and did not handle the reallocation correctly.
2165 The affected file is lib/silccore/silcpacket.c.
2167 * Fixed buffer overflow in silc_parse_nickname in the file
2168 lib/silcutil/silcutil.c.
2170 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * make install generates new server keys only if there is not
2175 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2177 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2178 Added check that if the NOREPLY is set then we will not send
2179 the away message. This avoids infinite loop of away messages
2180 if both clients are away. The affected file is
2181 lib/silcclient/client_prvmsg.c.
2183 * Fixed client crash if /NICK was given without arguments.
2184 Affected file lib/silcclient/command.c.
2186 * Server does not send the invite list in INVITE command back
2187 to the client if the list was not altered. Added this notion
2188 to the protocol spec as well. Affected file silcd/command.c.
2190 Fixed possible crash in INVITE command by checking the
2191 value of silc_server_get_client_route command.
2193 * Fixed the INVITE notify type handling. The arguments are now
2194 taken in correct order and client does not crash. The affected
2195 file is irssi/src/silc/core/silc-channels.c.
2197 Removed the "Inviting xxx to channel" message from the
2198 client library away and let the application handle it.
2199 Affected file lib/silcclient/command.c. Added that message
2200 to Irssi SILC client's message formats.
2202 * Fixed CMODE command crash in client. It now checks the
2203 amount of arguments correctly and does not crash. The affected
2204 file is lib/silcclient/command.c.
2206 * Do not create new channel automatically in silc_channels_join
2207 but check whether the channel by that name already exists.
2208 Affected file irssi/silc/core/silc-channels.c.
2210 * Do not send the SERVER_SIGNOFF to router if the disconnected
2211 entity was the router. Affected file silcd/server.c.
2213 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2214 SILC client as it was missing from there.
2216 Added the handling of the KICK notify to the Irssi SILC client
2217 as it was missing. Added "you have been kicked" message to
2218 Irssi SILC client's message modules formats.
2220 Added the handing of the KILL notify to the Irssi SILC client
2221 as it was missing. Added the kill message module formats
2224 The affected file is irssi/src/silc/core/silc-channels.c.
2226 * The router did not save the channel mode the server announced.
2227 Affected file silcd/packet_receive.c.
2229 * Fixed a possible crash in INFO command in server. If the
2230 server did not provide the server info it crashed. Affected
2231 file silcd/command.c.
2233 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Fixed the GETKEY command in the server to check also the
2236 global list. Otherwise the GETKEY would not work correctly
2237 in normal SILC server. Affected file silcd/command.c.
2239 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2241 * Fixed GETKEY crash, it crashed if the command did not succseed.
2243 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2245 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2246 is now real and not just an macro interface to GMP.
2248 Removed the entire GMP from the source tree and imported new
2249 NSS MPI library instead. Reason for removing GMP is that it is
2250 extremely large and compiles extremely slow. The NSS MPI
2251 is only a few files and compiles in less than 10 seconds.
2252 The speed is also about the same as GMP. The MPI is imported
2253 to lib/silcmath/mpi.
2255 If the system has GMP installed we will still use the GMP.
2256 If it is not then the NSS MPI will be compiled.
2258 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2260 * Merged a long nickname (127 characters long) crash bugfix from
2261 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2263 * Merged a freed memory reference bugfix from Irssi CVS tree.
2264 Affected file irssi/src/core/commands.c.
2266 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2268 * Added the server's public key sving and verification to the
2269 server when performing the SKE. This was missing and the
2270 remote server's (or router's) public key was accepted without
2271 checking whether we have it previously or trust it at all.
2272 Affected file silcd/protocol.c.
2274 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Check in the silc_server_timeout_remote if protocol is active
2277 and make sure that the protocol's final callback is called so
2278 that all memory if freed. Affected file silcd/server.c.
2280 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2282 * silc_server_whois_send_reply crashed the server if the nickname
2283 was 127 characters long. Affected file silcd/command.c.
2285 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Added sanity check to the silc_server_new_client. If the hostname
2288 is provided inside username then check that the provided hostname
2289 really is the same as the resolved one. If the hostname was not
2290 resolved then check it from the public key. Affected file is
2291 silcd/packet_receive.c.
2293 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2294 if the server disconnected us and the connection is not valid
2295 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2297 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2298 the library to the lib/silcutil/silcutil.[ch].
2300 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Close log file after open. Affected file
2303 lib/silcutil/silclog.c.
2305 * Check whether sock == NULL in silc_client_send_packet and return
2306 if it is. Affected file lib/silcclient/silcclient.c.
2308 * Check rec->entry == NULL in the Irssi SILC Client before
2309 sending the channel message. Affecte file is
2310 irssi/src/silc/core/silc-servers.c.
2312 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Merged a splitted window bugfix from Irssi CVS tree. The
2315 affected file is irssi/src/fe-text/textbuffer-view.c.
2317 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2318 It did not print nickname.
2320 * Improved the distributions system a bit.
2322 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2325 irssi/src/fe-text/gui-window.c.
2327 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2328 to in-active server. The affected file is
2329 irssi/src/silc/core/client_ops.c.
2331 * Resolve the client in USERS command reply if the entry does
2332 not have username resolved. The affected file is
2333 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2334 command to WHOIS command to really resolve stuff. The USERS
2335 is not used any more in any critical section so WHOIS can
2336 be used even though it might be slower than IDENTIFY.
2338 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2341 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2343 * Changed the protocol API a bit more consistent in the
2344 lib/silccore/silcprotocol.[ch].
2346 * Changed the following headers to ROBODoc format:
2348 lib/silccore/silcpayload.h
2349 lib/silccore/silcprotocol.h
2350 lib/silccore/silcsockconn.h
2352 All core library headers are now formatted.
2354 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Fixed a bug in Irssi SILC client; do not show that you are
2357 server/router operator if you really are not. Affected file is
2358 irssi/src/silc/core/client_ops.c.
2360 * Renamed silc_command_free_payload to silc_command_payload_free.
2361 Affected file lib/silccore/silccommand.h
2363 * Added silcmath.h to include the prototoypes of various routines
2364 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2367 * Changed the following headers to ROBODoc format:
2369 lib/silccore/silcchannel.h
2370 lib/silccore/silccommand.h
2371 lib/silccore/silcid.h
2372 lib/silccore/silcidcache.h
2373 lib/silccore/silcmode.h
2374 lib/silccore/silcnotify.h
2375 lib/silccore/silcpacket.h
2376 lib/silcmath/silcmath.h
2378 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2380 * Added checking to the server code not to start the server if
2381 ciphers and stuff are not configured properly. Affected files
2382 silcd/serverconfig.[h] and silcd/server.c.
2384 * Changed the layout of the header files of the public interfaces
2385 in the SILC libraries. The new layout supports ROBODoc
2386 documentation tool (and some others) so that it is easy to create
2387 a library reference manual. All the other headers and source
2388 code must still follow the CodingStyle document. Also source
2389 code must not include these ROBODoc stuffs, only the headers.
2390 Furthermore, all public interface headers must now be named
2391 by using `silc' prefix, example: silcapi.h, silccipher.h.
2392 Some files were renamed due to this. All the other headers
2393 must not be used as public interfaces. I will update the
2394 CodingStyle document later. Changed following headers, so far:
2396 lib/silcclient/silcapi.h
2397 lib/silccore/silcauth.h
2398 lib/silccore/silcprivate.h
2399 lib/silccrypt/silcdh.h
2401 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Removed silc_client_packet_send_flush from the client library
2406 as it is not needed. Affected file lib/silcclient/client.[ch].
2408 * Added printing of message of unresolved authentication method
2409 to the Irssi SILC client. Added it to the module formats.
2410 Removed the same message from the client library.
2412 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2414 * Added new distribution feature, DISTLABEL. Every distribution
2415 can define own preprocessor label that can be used in the
2416 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2417 file distributions, acconfig.h.pre and prepare.
2419 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Added Makefile.defines_int to include the actual definitions
2422 for Makefile.defines.in. Tested the new distribution system,
2423 created distributions and tested installation.
2425 * Added AWAY message printing to the Irssi SILC client. Added
2426 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2428 * Added SCONNECT command to call the SILC's CONNECT command.
2429 Cannot use CONNECT directly since Irssi uses that internally.
2430 Affected file irssi/src/silc/core/silc-servers.c.
2432 Added ACTION local command. It is same as ME command but takes
2433 the channel as mandatory argument.
2435 Rewrote some of the Irssi's help files to suite for SILC
2438 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Added Makefile.defines[.in] that should for now on be included
2441 in all Makefile.am file in the source tree. That file includes
2442 all common compilation definitions for SILC source tree.
2444 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Minor changes to the ./prepare script to change the package
2447 name according the distribution name to the configure.in.
2449 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Created new distribution system. Added file `distributions'
2452 that defines all the distributions that can be created out of
2453 the SILC source tree. The ./prepare script now reads that
2454 file to determine how to prepare the distributions. The
2455 first argument to the ./prepare is the name of the distribution
2456 and second is the version of the distribution. If given
2457 without arguments it creates the default (toolkit) distribution
2458 with the default version (defined in ./prepare).
2460 All Makefile.am files that are subject to the distributions
2461 are now named as Makefile.am.pre. These are ./Makefile.am
2462 and lib/Makefile.am. Others may be changed later.
2464 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Added invite list, ban list, some key management and connection
2467 error message printing to module formats in the Irssi SILC client.
2469 * Added new silc_client_set_away_message to set the away message
2470 that is back to the person who sent private message. The
2471 affected file lib/silcclient/silcapi.h and the
2472 lib/silcclient/client_prvmsg.c.
2474 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Fixed the private message sending in the Irssi SILC client,
2477 added local command KEY to the Irssi SILC client.
2479 Added key management and key agreement message formats to the
2480 irssi/src/fe-common/silc/module-formats.[ch].
2482 Added USERS (alias WHO) printing, server/router operator
2483 indication and LIST command printing to the module formats.
2485 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2487 * Fixed channel joining notify handling, cumode notify handling
2488 from Irssi SILC client.
2490 * Added SILC specific module-formats to the Irssi SILC client so
2491 that SILC specific message hilighting, colors etc is possible.
2492 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2494 Added channel mode, channel user mode, actions, notices,
2495 whois and whowas printing to the the module-formats.c.
2497 * Fixed a bug in channel deletion in the server. The channel
2498 is not left to the cache even if the channel founder auth mode
2499 is set when there are no users anymore on the channel. Affected
2500 file silcd/server.c.
2502 * The silc_net_localhost now resolves the entire hostname including
2503 the domain name. Affected file lib/silcutil/silcnet.c.
2505 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Changed the ask_passphrase client operation to be ascynchronous.
2508 It has now a completion callback and a context that the
2509 application must call after it has got the passphrase from
2510 the user. Affected files lib/silcclient/silcapi.h,
2511 lib/silcclient/protocol.c, lib/silcclient/command.c and
2514 Added SilcAskPassphrase callback that the application calls
2515 to deliver the passphrase to the library.
2517 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2518 The public key verification and especially a certificate
2519 verification is asynchronous procedure.
2521 Added new SILC_SKE_STATUS_PENDING status to indicate the
2522 request is pending and a callback will be called to finalize
2525 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2526 indicate that remote end did not send its public key (or
2527 certificate), even though we require it. Added check for this
2528 condition in the SKE. This was a security bug, now fixed.
2530 Defined new SilcSKEVerifyCbCompletion callback that is called
2531 when the verification process is completed.
2533 The affected files lib/silcske/silcske_status.h and
2534 lib/silcske/silcske.[ch].
2536 * Changed the verify_public_key client operation to be async
2537 as well. Defined SilcVerifyPublicKey callback that is used to
2538 indicate the success of the public key verification process.
2540 Changed the server and client to use the new async client
2543 * Changed the Irssi SILC client's internal scheduler to be called
2544 twice as many times as it used to be. As a result the client
2545 should be a bit faster now. Affected file is
2546 irssi/src/silc/core/silc-core.c.
2548 * Added support to Irssi SILC client of asynchronous public key
2549 verification and passphrase inquiry. Affected file is
2550 irssi/src/silc/core/silc-core.c.
2552 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2554 * Do not say "You have left channel %s" in client library.
2555 Moved it to the application. Affected files are
2556 lib/silcclient/command.c and silc/client_ops.c.
2558 * Fixed silc_client_get_clients. Command context was not
2559 duplicated and was freed memory in the callback. Affected
2560 file lib/silcclient/idlist.c.
2562 * Do not say "you are now talking..." on JOIN command in the
2563 client library. The appliation must handle it.
2565 * Do not say ".. changed topic to" in command reply in the
2566 client libary. The application must handle it.
2568 * Fixed TOPIC command sending in the client library.
2570 * Fixed a memory leak in silc_client_command_free in the file
2571 lib/silcclient/command.c.
2573 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Imported a modified version of Irssi client to the source tree.
2576 The Irssi will be used to create a new client called
2577 Irssi SILC. Imported to irssi/.
2579 Added silc_core_init_finish function to the Irssi. Affected
2580 file irssi/configure.in.
2582 A lot changes in the Makefile.ams around the irssi tree.
2584 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Do not rehash if the new size is same as the old size of the
2587 hash table, in the silc_hash_table_rehash*. The affected file
2588 lib/silcutil/silchashtable.c.
2590 * Replaced hash_table_del_by_context calls from the server
2591 (when channel->user_list and client->channels) to the
2592 hash_table_del as it is sufficient and faster.
2594 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2596 * Added silc_hash_table_list, silc_hash_table_get and the
2597 SilcHashTableList structure to provide an alternative way to
2598 traverse the hash table. The affected files are
2599 lib/silcutil/silchashtable.[ch].
2601 * Changed the server's idlist routines to use the hash table
2602 routines to optimize the code.
2604 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Replaced the client entry's `channel' list and channel entry's
2607 `user_list' list to hash tables for optimized lookup. Changed
2608 the code to use the hash table interface around the code.
2609 Affected file lib/silcd/idlist.[ch].
2611 * Added `auto_rehash' boolean argument to the function
2612 silc_hash_table_alloc to indicate whether the hash table should
2613 auto-rehash when it thinks is appropriate time. It will
2614 increase the hash table size if the there is twice as much
2615 entries in the table than the size of the table, and will
2616 decrease the size if there are twice as less entries than
2617 the size of the table.
2619 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2621 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2623 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2625 * silc_idcache_purge_by_context deletes the entry now by context
2626 as it is supposed to do. Affected file lib/silccore/idcache.c.
2628 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2629 client is not anymore valid (WHOWAS givens the info) and not
2630 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2632 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Removed the `data' and `data_len' arguments from the ID Cache
2635 interfaces and added `name' argument. ID Cache does not handle
2636 anymore the binary data only a names associated with given ID.
2638 * When hashing a Client ID with silc_hash_id the entire ID is
2639 not hashed anymore, instead only the hash of the Client ID is
2640 hashed. This way we can access the Client ID from the cache
2641 with Client ID but with the hash of the ID (which is a hash of
2642 the nickname) as well without any difference in performance.
2644 Added also silc_idcache_find_by_id_one_ext to do one on one
2645 searching when we have the actual ID. Added also function
2646 silc_hash_client_id_compare. The affected files are
2647 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2649 * When hashing the name associated with a ID it is always done
2650 in lowercase. This way we can access the cache without worrying
2651 about case-sensitivity, even though, for example nicknames are
2654 * Fixed a bug in server with channel message sending. It put
2655 wrong ID type as destination ID. The affected file
2656 silcd/packet_send.c.
2658 * silc_idcache_del_by_context now deletes from all hash tables
2659 by context. Affected file lib/silccore/idcache.c.
2661 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Changed the client library to use the new ID Cache interface.
2664 Changes around the source tree.
2666 * Added silc_hash_table_rehash_ext to rehash with specific
2667 hash function. Affected file lib/silcutil/silchashtable.[ch].
2669 * Added silc_hash_string_compare to compare two strings in the
2670 hash table. Affected file lib/silcutil/silcutil.[ch].
2672 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2674 * Added new function silc_idcache_del_by_context into the
2675 lib/silccore/idcache.[ch].
2677 * Changed the server's ID list routines to use the new ID Cache
2678 interface. Changes around the source tree.
2680 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2682 * Added silc_hash_table_del[_by_context]_ext functions in to the
2683 lib/silcutil/silchashtable.[ch].
2685 Removed silc_hash_table_find_all* routines and added new
2686 silc_hash_table_find_foreach to replace them.
2688 Added silc_hash_table_replace_ext function as extended
2689 replacing function. Separated the simple hash table interface
2690 from the extended hash table interface in the file
2691 lib/silcutil/silchashtable.h.
2693 * Fixed minor bugs and changed it to use some of the new
2694 hash table functions in lib/silccore/idcache.c
2696 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2698 * Added new function silc_hash_table_find_all to return all keys
2699 in the hash table by the specified key. As the hash table is
2700 collision resistant it also makes it possible to have several
2701 duplicate keys in the hash table. This function may be used to
2702 find all of the keys from the hash.
2704 Added user_context arguments to the SilcHashFunction,
2705 SilcHashCompare and SilcHashDestructor to deliver user specified
2708 Added new fuctions silc_hash_table_find[_all]_ext to do
2709 extended lookup with specified hash and compare functions and
2710 specified user contexts.
2712 Added new function silc_hash_table_add_ext to add the key
2713 with specified hash function and user context.
2715 Added new function silc_hash_table_foreach to traverse all
2716 entrys in the hash table. Added SilcHashForeach callback
2719 Added new function silc_hash_table_del_by_context to delete
2720 the entry only if the context associated with the key matches.
2722 Affected files are lib/silcutil/silchashtable.[ch].
2724 * Removed silc_hash_[server/client/channel]_id and added just
2725 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2726 silc_hash_id_compare to compare two ID's using as the hash table
2727 comparison function. Added also silc_hash_data to hash
2728 binary data and silc_hash_data_compare to compare it.
2730 * Removed silc_idlist_find_client_by_hash as it is not needed
2731 anymore. Affected file silcd/idlist.[ch].
2733 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2734 to use internally the SilcHashTable. The new ID Cache is a lot
2735 faster than the old one. Some of the ID Cache interface was also
2736 rewritten and obsolete and stupid functions were removed.
2738 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2740 * Added entry_count field to the SilcHashTable to keep the number
2741 of the entries in the table. Implemented the function
2742 silc_hash_table_rehash. Added new function
2743 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2745 Fixed a minor bug in silc_hash_table_free.
2747 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2748 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2749 into the lib/silcutil/silcutil.[ch].
2751 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Implemented a collision resistant hash table into the
2754 lib/silcutil/silchashtable[ch]. See the header and the source
2755 for the SilcHashTable API.
2757 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2759 * Merged dotconf version 1.0.2 into lib/dotconf.
2761 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2763 * Do not compile anything in lib/silcsim/* if the SIM support
2764 is not enabled. The tree should now compile without problems
2767 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Compiled the SILC under cygwin. Compiled and tested briefly
2770 without problems. More tests needed. The SIMs didn't compile
2773 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2775 * Fixed possible crash in silc_get_username in the
2776 lib/silcutil/silcutil.c.
2778 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Fixed a va_arg in silc/client_ops.c.
2782 * Oops, RC5 routines were named AES and caused some problems
2783 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2785 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Added new SilcIDIP structure into the lib/silccore/id.h and
2788 replaced the old `ip' fields from all SILC ID's to that type.
2789 This is a step towards IPv6 support.
2791 The silc_id_get_len takes now the ID as an extra argument.
2792 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2793 both IPv4 and IPv6 based ID's.
2795 The affected files are lib/silccore/id.[ch] and other files
2796 around the tree using these routines.
2798 * Removed the ID length arguments in server from various
2799 silc_server_send_notify_* routines -> they are not needed
2802 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Fixed memory leak in silc_encode_pem_file in the file
2805 lib/silcutil/silcutil.c.
2807 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Check minor version as well in the SKE. Affected files are
2810 silcd/protocol.c and lib/silcclient/protocol.c.
2812 * Added --identifier option to the server so that an identifier
2813 can be when creating the public key for the server. Affected
2814 file is silcd/silcd.c.
2816 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2817 lib/silccrypt/silcpkcs.c.
2819 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2821 * Register default ciphers and stuff when using -C option with
2822 the server. Affected file sildc/silcd.c.
2824 * Put back the servers public key filename format, it is better
2825 than the new one. For now, the client keys are saved with the
2826 new filename format. The affected file silc/client_ops.c.
2828 * Implemented the Cipher API for the rest of the ciphers that
2829 did not implement it or implemented it the wrong way.
2831 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2833 * Register default ciphers and stuff when using the -S option
2834 in the client. Affected file silc/silc.c. Same also when
2835 creating new key pair with -C option.
2837 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2839 * Fixed the silc_verify_public_key client operation function to
2840 save the public keys differently. The fingerprint is now
2841 used as filename and not the hostname. This way also the
2842 client keys are saved uniquely and not with hostnames. The
2843 affected file is silc/client_ops.c.
2845 * Trimmed the silc_hash_fingerprint function to remove extra
2846 whitespaces from the end of the fingerprint. The affected
2847 file is lib/silccrypt/silchash.c.
2851 * Added silc_cipher_register_default function to register all
2852 default ciphers. It can be used when configuration files
2853 does not exist and the application does not want any specific
2854 ciphers in any specific order.
2856 The SilcDList is now used as silc_cipher_list dynamically
2857 allocated cipher list. Removed the static list all together
2858 and now all ciphers must be allocated to the dynamic list.
2859 The silc_cipher_alloc routine was changed to check only the
2862 All silc_cipher_* routines that used to return int returns
2865 The affected files lib/silccrypt/silccrypt.[ch].
2867 * The same thing was done to silc_hash_* as for silc_cipher_*
2868 routines. Affected files lib/silccrypt/silchash.[ch].
2870 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2871 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2872 Added also silc_pkcs_[un]register[_default] functions.
2873 Removed the data_context from the PKCS API.
2875 * Added silc_hmac_register_default function to register default
2876 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2877 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2878 to unregister all hmacs at once.
2880 * Register the default ciphers, hash functions, PKCSs and HMACs
2881 if client's configuration file does not exist. The affected
2884 * The client did not load the hash functions from the SIM
2885 modules at all. Added support for this. Affected file is
2886 silc/clientconfig.c.
2888 * When decoding public key with silc_pkcs_public_key_decode, check
2889 the supported algorithm only if PKCS are registered. Affected
2890 file lib/silccrypt/silcpkcs.c. The same was done with the
2891 silc_pkcs_private_key_decode.
2893 * Fixed the SILC List routines to keep the list always in order.
2894 It used to change the list's order when traversing the list but
2895 not it preserves the order. Affected file lib/trq/silclist.h.
2897 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2899 * Added the client library to use the SilcSocketConnection's
2900 reference counter (by silc_socket_dup) to prevent the bug that
2901 the socket object may be freed underneath async operation.
2903 * The name resolv library checking fixes in the configure.in.pre.
2906 * Created new version of the protocol drafts for future
2907 development. The -03 drafts are the ones that will be changed
2908 in the trunk now and the -02 will remain as they are.
2910 * Send list of CUMODE notifys to the router when announcing
2911 the channel users to the router. Affected file silcd/server.c.
2912 If the router receiving channel founder CUMODE for a channel
2913 that already has channel founder it will send CUMODE notify
2914 to the sender to remove the channel founder rights from the
2915 announced client. Affected file silcd/packet_receive.c.
2917 * The CUMODE notify may now use Server ID as well as the entity
2918 who changes the mode. Updated protocool specs.
2920 * Updated INSTALL and README files.
2922 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * New web pages in the http://silc.pspt.fi. The pages was
2929 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Implemented the [DenyConnectin] config section in the server.
2932 Added silc_server_config_denied_conn to check whether incoming
2933 connection is denied. Affected file silcd/serverconfig.[ch].
2935 * Do not check the ports when checking the incoming configuration
2936 data if the port is 0, meaning any. Affected file is
2937 silcd/serverconfig.c.
2939 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Fixed buffer overflow in silc_string_compare in the file
2942 lib/silcutil/silcutil.c.
2944 * Fixed double free in silc_server_command_leave in the file
2947 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Fixed the version checking in the server. Affected file is
2952 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2954 * Fixed the configuration data fetching when accepting new
2955 connections in the server. Affected file silcd/server.c.
2957 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2959 * Added `sender_entry' argument to the function
2960 silc_server_packet_relay_to_channel so that we can check
2961 whether some destination actually belongs to the same route
2962 the sender belongs (ie, we must not resend the packet to the
2963 sender). Affected file silcd/packet_send.[ch].
2965 * Added `servername' field to the SilcClientEntry in the server
2966 to hold the name of the server where client is from. Affected
2967 file is silcd/idlist.h.
2969 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Moved the channel message encrypting in the router betwen
2972 router connections from silc_server_channel_message to the
2973 silc_server_packet_relay_to_channel since we want to check
2974 whether we have anybody channel before encrypting anything.
2975 Affected files silcd/packet_[receive/send].c.
2977 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2979 * Fixed the [AdminConnection] server config section to support
2980 multiple entries. Affected file silcd/serverconfig.c.
2982 * Added support into the server to check the validity of the
2983 incoming connection before executing any KE or authentication
2986 * The connection configuration is now saved to the KE and
2987 connection auth protocol contexts and not fetched anymore in
2988 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2990 * The local hosts listenning address and port is also resolved
2991 now when starting the server. We want to have the socket object
2992 to include the real address and port for the listener. Added
2993 new function silc_net_check_local_by_sock into the files
2994 lib/silcutil/silcnet.[ch].
2996 * Fixed a broadcast bug in server -> do not broadcast if we
2999 * Fixed a routing bug. Do not route broadcast packets ever.
3000 Broadcast packets must be processed always and not routed since
3001 they may be destined to some other host than yourself and thus
3002 would get routed without no good reason. Affected file is
3005 * Added function silc_server_config_is_primary_route to check
3006 whether primary router connection has been configured (a router
3007 configuration that we are initiating). If there is not, we
3008 will assume that there is only two routers in the SILC network
3009 and we will use the incoming router connection as our primary
3010 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3012 * Changed the order of the broadcasting. Broadcast _after_ the
3013 packet has been processed not before. Affected file is
3016 * Fixed a [ClientConnection] parsing bug. The port was never
3017 parsed correctly thus resulting to port 0. Affected file
3018 silcd/serverconfig.c.
3020 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3021 argument and did not set the broadcast packet flag. Affected
3022 file silcd/packet_send.c. Fixed same bug in the function
3023 silc_server_send_notify as well.
3025 * If we receive NEW_ID packet for our own ID in the server, ignore
3028 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Removed the nickname from the Private Message Payload.
3033 Updated the code and the protocol specs.
3035 * Updated protocol specs for submitting to the IETF.
3037 * Tweaked the Random Number Generator a bit. Affected file
3038 lib/silccrypt/silcrng.c. Exported a new function
3039 silc_rng_[global]_add_noise which can be used to add more
3042 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Do not parse packets with different timeout when protocol
3045 is active -> may cause problem with rekey. Affected file
3048 * When server receives signoff notify it must not create
3049 new channel key if the client is on any channels since the
3050 sender of the signoff notify will create it.
3052 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3054 * Added printing of error messages during SKE protocol from the
3055 failure packet sent by server during SKE. Affected file
3058 * Removed the client's failure_callback handling with timeout
3059 and handle it immediately when received.
3061 * The SKE library returned wrong type in SUCCESS and FAILURE
3062 packets. They must be 32 bit MSB not 16 bit MSB.
3064 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Ok, rewrote the logic of the re-key and now it seems to work.
3067 I tested it on high traffic with frequent re-keys without
3068 problems. Added hmac_receive (and renamed hmac to hmac_send)
3069 in SilcClientConnection in lib/silcclient/client.h and
3070 in SilcIDListData in silcd/idlist.h. Also, removed the
3071 SilcPacketParserContext's cipher and hmac fields as they are
3072 not needed anymore and actually caused some problems when
3073 the ciphers and hmac's changed underneath the packet parser.
3075 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * If re-key protocol is active then process the incoming packets
3078 synchronously since we must assure that icoming packets encrypted
3079 with the old key is processed before the new keys is set to
3080 use. This is true other packets than for REKEY packets.
3081 Affected file silcd/server.c. The same was done to client library
3082 as well, affected file lib/silcclient/client.c.
3084 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Fixed bug in client and server to accept the force send if
3087 the packet is send from silc_[server/client]_packet_process
3088 function. Otherwise the packets are never delivered, oops.
3090 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Disable force sending of packets when REKEY protocol is active.
3093 We must assure that no packet is sent directly when rekey is
3094 performed. All packets must be sent through packet queue.
3095 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3096 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3097 function is silc_[server/client]_packet_send_real to check
3100 * Replaced the SIM paths from example config files to
3101 /usr/local/modules. Also, make install creates now
3102 /usr/local/silc/logs directory to hold all the SILC server
3105 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Made the configure.in.pre work on Solaris. Patch by salo.
3109 * Made all ciphers compatible with non-x86 machines. Defined
3110 CBC mode macros into lib/silccrypt/ciphers_def.h.
3112 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Fixed the make install.
3116 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * When MAC computation fails the silc_packet_decrypt returned 0
3119 even though it was supposed to return -1. Fixed this. The
3120 affected file is lib/silccore/silcpacket.c.
3122 * Do not replace the config files in /etc/silc (in make install)
3123 if they already exist. Affected file ./Makefile.am.
3125 * Do not send re-key packets immediately but through packet queue.
3126 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3128 * Changed silc_net_check_host_by_sock to return FALSE if the
3129 IP/DNS could not be resolved. Though, it returns the IP address
3130 now even if it could not resolve it (but returns also FALSE).
3131 Affected file lib/silcutil/silcnet.[ch].
3133 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3135 * Added silc_pkcs_decode_identifier to decode the public key's
3136 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3137 Added also silc_pkcs_free_identifier. Added also new context
3138 SilcPublicKeyIdentifier.
3140 * Added -S option to the silc client. It is used to dump the
3141 contents of the specified public key file.
3143 * Changed the PKCS api to return the public key length when
3144 setting the public key.
3146 * Fixed a fatal bug in the public and private key file loading.
3147 Affected file lib/silccrypt/silcpkcs.c.
3149 * Execute the packet parsing for client with zero (0) timeout
3150 if the protocol is active. Affected file silcd/server.c.
3152 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Made the key generation options to the silcd program. Added
3155 -C option, equivalent to client's option.
3157 * Added new [ServerKeys] config section to the server. It
3158 configures the server's public and private key.
3160 * Defined generic Public Key Payload into the protocol
3161 specification to send specific type of public keys and
3164 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3165 public key or certificate.
3167 * Implemented the GETKEY command to the server and to the
3168 client library and on user interface.
3170 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3172 * Made preliminary `make install' work.
3174 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Added SilcServerRekey context into silcd/idlist.h.
3178 * Added the PFS support as defined in the specification to the
3179 SKE protocol. Affected files lib/silcske/*.c.
3181 * Added `ske_group' field to the SilcServerRekey context to hold
3182 the number of the SKE group that is used with PFS in re-key.
3183 Affected file silcd/idlist.h.
3185 * Added PFS re-key support to the server. Affected file is
3188 * Added silc_protocol_cancel to cancel execution of the next
3189 state of the protocol. Affected file is
3190 lib/silccore/silcprotocol.[ch].
3192 * Added the re-key support with and without PFS to the client
3193 library. Re-key is performed once in an hour, by default.
3195 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3196 Added silc_client_rekey_callback and silc_client_rekey_final.
3197 Affected files are lib/silcclient/protocol.[ch] and
3198 lib/silcclient/client.[ch].
3200 * Removed the `hmac_key' and `hmac_key_len' fields from the
3201 SilcClientConnection structure; not needed. Affected file is

3206 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Do not ask whether user wants to use the negotiated private key
3209 for private messages, just use it. Affected file is
3210 silc/local_command.c.
3212 * Added `send_enc_key' and `enc_key_len' fields to the
3213 SilcIDListData structure since they are needed in the re-key
3214 phase. Affected file is silcd/idlist.[ch].
3216 * Implemented the simple re-key protocol into the server.
3217 Affected files silcd/server.c and silcd/protocol.[ch]. The
3218 re-key will be performed once in an hour, by default.
3220 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3221 Added silc_server_rekey, silc_server_rekey_callback and
3222 silc_server_rekey_final.
3224 * Removed Tunneled flag from the protocol. Updated the code
3225 and the specifications.
3227 * Adde `pfs' field to the SilcIDListData to indicate whether
3228 the PFS is to be performed in the re-key. Affected file is
3231 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3234 int64 of at least the xintXX size. If void * is less that 4
3235 bytes uint32 * will be used. Defined bool as boolean.
3237 * Changed _ALL_ unsigned long and unsigned int to uint32,
3238 unsgined short to uint16 in the source tree.
3240 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3241 not handle clients that has entry->data.registered == FALSE.
3242 They are not in the network anymore. Affected file is
3245 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Implemented the sending of the SERVER_SIGNOFF notify in the
3248 server. Affected file is silcd/server.c.
3250 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3251 Added also silc_notify_payload_encode_args into the
3252 lib/silccore/silcnotify.[ch].
3254 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3255 Affected file silcd/packet_receive.c.
3257 * Implemented the SERVER_SIGNOFF notify handling in the client
3258 library. Affected file lib/silcclient/client_notify.c. Also,
3259 implemnted the printing of the SERVER_SIGNOFF info to the
3260 application. Affected file silc/client_ops.c.
3262 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3263 if the deleting was successful. Affected file silcd/idlist.[ch].
3265 * Added support for public key authentication in the connection
3266 authentication protocol in the client library. Affected file
3267 lib/silcclient/protocol.c.
3269 * Changed the server's silc_idlist_get_clients_by_* interface
3270 to support already allocated array so that new entries may be
3271 added to pre-allocated array. Affected file silcd/idlist.[ch].
3272 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3273 and command replies.
3275 * All command reply functions in the server now calls the
3276 pending command callback even if error occured. This way the
3277 error will be delivered to the client as well. Affected files
3278 silcd/command.c and silcd/command_reply.c.
3280 * Fixed INFO command to return local server's info if no server
3281 was provided. Affected file lib/silcclient/command.c.
3283 * Removed RESTART command for good. Updated the code and the
3286 * Rewrote parts of the task system. It is a bit simpler now.
3287 Removed unsued task priorities. The affected files are
3288 lib/silcutil/silctask.[ch].
3290 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Moved the USERS printing from the library to the application.
3293 Affected files lib/silcclient/command.c and silc/client_ops.c.
3295 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Added channel key re-key support. The re-key is perfomed
3300 only by the router and is done once in an hour. Added `rekey'
3301 field to the SilcChannelEntry in the server. Affected files
3302 silcd/server.c and silcd/idlist.h.
3304 * Added silc_task_unregister_by_context into the file
3305 lib/silcutil/silctask.[ch].
3307 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Added SILC_UMODE_GONE mode to indicate when the client is not
3310 present in the SILC network. Added also support to the local
3311 command AWAY that will set this mode. Added support of showing
3312 "xxx is gone" in WHOIS command. The USERS command shows the
3313 gone status as well.
3315 * Fixed setting server and router operator privileges in the
3316 server's UMODE command. Affected file silcd/command.c.
3318 * Merged the SKE KE1 and KE2 payloads into one payload. The
3319 new KE payload is equivalent to the old KE2 payload.
3321 Cleaned up the SKE Start Payload parsing. It now uses the
3322 simple buffer unformatting to do the parsing. A lot faster
3325 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3326 to the SKE that is used to indicate whether both of the SKE
3327 parties should perform authentication. By default only the
3328 responder performs authentication. By setting this flag also
3329 the initiator must do authentication. By default it is unset
3330 since in normal SKE case, client to server connection, only
3331 the responder should do authentication. When doing SKE between
3332 two clients both should perform authentication. Updated the
3333 code and the protocol specs.
3335 * A little fix to IDENTIFY command in the server. Search the
3336 client first by hash not nickname. Affected file is
3339 * Fixed the silc_client_close_connection to support closing
3340 the client to client connections wihtout deleting too much
3341 data. Affected file lib/silcclient/client.c.
3343 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3344 are received if protocol used to be active but is not anymore
3345 the application would crash due to NULL pointer dereference.
3346 Affected files silcd/server.c and lib/silcclient/client.c.
3348 * Added `hash' field to the SilcClientConnection to include
3349 the hash function negotiated in the SKE protocol.
3351 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3352 to set the channel founder authentication data. A client can
3353 claim the founder rights later by providing the authentication
3354 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3355 This way the channel founder can regain the channel founder
3356 privileges even it is left the channel. This works only on
3357 local server and the client must be connected to the same
3358 server to be able to regain the founder rights. Updated the
3359 protocol specs accordingly.
3361 Added support to the CMODE command in the client to set the
3362 founder auth data. Read the README to see how to set it.
3364 Added support to the CUMODE command to claim the founder
3365 rights. Read the README to see how to do it.
3367 Added support for the founder authentication to the Channel
3368 Entry in the server. Affected file silcd/idlist.h.
3370 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3371 server's CMODE command. Affected file silcd/command.c.
3373 * Added the following new functions into lib/silccore/silcauth.[ch]:
3374 silc_auth_get_method and silc_auth_get_data.
3376 * The server now saves the remote hosts public key to the
3377 SilcIDListData pointer. Affected file silcd/protocol.c.
3379 * The normal server now does not remove the channel entry from
3380 the cache if the founder authentication data is set. It used
3381 to remove it if the founder was the last one on the channel on
3382 the server and left the channel. The auth data is saved and
3383 if the channel is re-joined later the old entry is used with
3384 the old auth data. Affected files silcd/command_reply.c and
3387 * Removed the `pkcs' field from the SilcIDListData structure
3388 in the server; it is not used. Affected file silcd/idlist.h.
3390 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3392 * Fixed packet processing on slow links. Partial packets were
3393 never re-processed because the incoming data buffer was cleared
3394 by the application. Application must not directly clear the
3395 sock->inbuf, the packet processing routines handle it. Fixed
3396 this in client library and in server.
3398 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Fixed the WHOIS and IDENTIFY send reply function to really
3401 check whether to send list or just one entry. Affected file
3404 * Cleaned up the LEAVE command's channel key distribution. The
3405 affected file silcd/command.c.
3407 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3408 can enforce the channel mode as well. In that case the ID
3409 includes the ID of the server. The code now enforces the
3410 mode change if the router have different mode than the server.
3412 * The notify client operation with CMODE_CHANGE notify can now
3413 return NULL client_entry pointer if the CMODE was not changed
3414 by client. Application must check for this.
3416 * Added <Server ID> argument to INFO command to support server
3417 info fetching by Server ID.
3419 * Added silc_server_announce_get_channel_users to get assembled
3420 packets of channel users of the specified channel. Affected
3421 file silcd/server.[ch].
3423 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3424 was freed underneath the ID Cache.
3426 * Re-announce clients when the server received CHANNEL_CHANGE
3427 notify from the router. Affected file silcd/packet_send.c.
3429 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3431 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3432 crashed since it did not handle the fact that there is no cipher
3433 called "3" and didn't check the error condition. Now fixed.
3435 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3436 flag. It can be used to send message requests.
3438 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Implemented the RESTART command in the client.
3442 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3443 notice type messages. Added notice printing to the user
3446 * The channel keys are not re-generated if the channel's mode
3447 is PRIVKEY, ie private key on the channel exists. Affected
3448 files silcd/server.c and silcd/command.c.
3450 * Fixed a little bug in channel message delivery when channel
3451 private keys are set in the server. Affected file is
3452 silcd/packet_send.c.
3454 * Changed the setting on channel->on_channel = TRUE from the
3455 silc_client_save_channel_key to the JOIN command reply. The
3456 key payload is not received if the private channel key is set.
3457 Affected file lib/silcclient/command_reply.c and the
3458 lib/silcclient/client_channel.c.
3460 * When the CMODE_CHANGE notify is sent and the channel private
3461 key mode is removed the channel key must be re-generated in
3462 other cells as well. Added this support for the router in the
3463 silcd/packet_receive.c.
3465 * Added new local command NOTICE to send notice message on
3466 channel. Affected file silc/local_command.[ch].
3468 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Added new local command ME to the client. It is used to send
3471 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3472 some action. Affected file silc/local_command.[ch].
3474 * Changed channel_message and private_message client operations
3475 to deliver the message flags to the application. Added also
3476 the `flags' arguments to the silc_client_send_channel_message
3477 and silc_client_send_private_message functions. Affected file
3480 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Redefined the Private Message Payload to support private message
3483 keys and to support the new private message flags. Updated
3484 the protocol specs. Flags makes it possible to have for example
3485 CTCP style messages.
3487 * Added new type SilcPrivateMessagePayload and defined an API
3488 for it in the lib/silcclient/silcprivate.[ch].
3490 * Tested private message private keys successfully. Tested the
3491 private message key set, unset and list commands with the new
3494 * Redefined the Channel Message Payload to include the channel
3495 message flags (equal with private message flags) to support
3496 for example CTCP style messages.
3498 * Defined some of the message (for channel and private message)
3499 flags. Updated the protocol specs and added the flags to the
3500 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3502 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Added SilcKeyAgreementStatus type to the key agreement routines
3505 to indicate the current status and error if one occured.
3506 The status types are defined in the lib/silcclient/silcapi.h.
3508 * Added new local command KEY that is used to set and unset private
3509 keys for channels, set and unset private keys for private messages
3510 with remote clients and to send key agreement requests and
3511 negotiate the key agreement protocol with remote client. The
3512 key agreement is supported only to negotiate private message keys,
3513 it currently cannot be used to negotiate private keys for channels,
3514 as it is not convenient for that purpose.
3516 * Fixed a minor pending callback setting bug in the function
3517 silc_client_get_client_by_id_resolve, now the function works.
3518 Affected file lib/silcclient/idlist.c.
3520 * Added function silc_net_get_local_port to get local bound
3521 port by socket. Added to lib/silcutil/silcnet.[ch].
3523 * Added `sockets' and `sockets_count' fields to the SilcClient
3524 object. They hold the sockets of the listenning sockets in
3525 the client. Listenning sockets may be for example the key
3526 agreement server. Affected file lib/silcclient/client.[ch].
3527 Added functions the silc_client_add_socket and the
3528 silc_client_del_socket. They are exported to the application
3531 * Added ~./silc/clientkeys to support other client's public keys.
3533 * Renamed verify_server_key client operation to verify_public_key
3534 and added one argument to indicate the type of the connection
3535 (server, client etc.).
3537 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3539 * Added silc_server_connection_auth_request to handle the
3540 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3541 silcd/packet_receive.[ch].
3543 * Added silc_server_send_connection_auth_request into the
3544 silcd/packet_send.c to send the connection auth request packet.
3546 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3549 * Fixed the public key authentication in responder side in the
3550 server. The `auth_data' pointer includes the SilcPublicKey
3551 not the path to the public key. Affected file silcd/protocol.c.
3553 * Implemented the public key authentication in the initiator side
3554 in the server. Affected file silcd/protocol.c.
3556 * Removed the [RedirectClient] config section from the server
3557 configuration. Is not needed and I don't want to implement it.
3559 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3561 * Cleaned up the CMODE command in the server. It now works
3562 correctly and supports all the modes defined in the protocol.
3563 Affected file is silcd/command.c.
3565 * Added `hmac_name' field to the SilcChannelEntry in the server
3566 to hold the default HMAC of the channel. It can be set when
3567 creating the channel (with JOIN command). Affected files
3570 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3571 type to indicate the change of the current cipher and hmac
3572 on the channel. Client can safely ignore the <cipher> argument
3573 (if it chooses to do so) since the CHANNEL_KEY packet will
3574 force the channel key change anyway. The <hmac> argument is
3575 important since the client is responsible of setting the new
3576 HMAC and the hmac key into use.
3578 * Fixed the CMODE command in the client library as well.
3580 * Tested CMODE command in router environment successfully.
3582 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Show the version of the remote client (or server) when connecting
3585 to the server. It is logged to the log file. Affected file
3586 is silcd/protocol.c.
3588 * Fixed the KILLED notify handling in the client library. The
3589 client must be removed from all channels when receiving the
3592 Also, do not remove the client entry when giving the KILL
3593 command but when the KILLED notify is received.
3595 * Removed silc_idlist_find_client_by_nickname from the server.
3596 Not needed anymore. Affected files silcd/idlist.[ch].
3598 * Implemented the CHANNEL_CHANGE notify type handling to the
3599 server. Affected file silcd/server.c.
3603 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Added silc_server_send_notify_invite to send the INVITE
3606 notify between routers.
3608 * Implemented the INVITE command correctly to the server.
3610 * Implemented the INVITE notify type handling in the server.
3612 * Implemented the INVITE command to the client library and on the
3615 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3617 * Added function silc_server_get_client_resolve to find the
3618 client entry by ID from all ID lists and then resolve it
3619 (using WHOIS) if it cannot be found. Affected file is
3622 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Implemented the BAN command to the client library.
3626 * The JOIN command in the server now checks the invite list
3629 * Changed the silc_command_reply_payload_encode_va and the
3630 silc_command_payload_encode_va to support that if argument is
3631 NULL it ignores and checks the next argument. Affected file
3632 lib/silccore/silccommand.c.
3634 * Added silc_server_send_notify_ban to send the BAN notify
3635 type between routers.
3637 * Chaned the silc_notify_payload_encode to support that if
3638 argument is NULL it ignores and checks the next argument.
3639 Affected file lib/silccore/silcnotify.c.
3641 * Tested ban lists in router environment successfully.
3643 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3645 * Implemented BAN command to the server, in silcd/command.[ch].
3647 * Removed the BAN and INVITE_LIST modes from the CMODE command
3650 * Added function silc_string_match to regex match two strings.
3651 Affected files lib/silcutil/silcutil.[ch].
3653 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Redefined parts of the SilcChannelEntry in the server to support
3656 the new ban and invite lists.
3658 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Redefined the INVITE command. The same command can be used to
3661 invite individuals to the channel but also to manage the invite
3662 list of the channel (to add to and remove from the invite list).
3663 Updated the protocol specs.
3665 * Added new command SILC_COMMAND_BAN that can be used to manage
3666 the ban list of the channel. Updated the protocol specs.
3668 * Removed the channel modes: the SILC_CMODE_BAN and the
3669 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3670 in the CMODE command. The equivalent features are now available
3671 using INVITE and BAN commands. Updated the protocol specs.
3673 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3674 in the network about change in the current ban list. The notify
3675 type is not used by the client.
3677 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3678 support the invite lists.
3680 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3682 * Added new function silc_string_regexify that converts string
3683 including wildcard characters into regex string that can
3684 be used by the GNU regex library. Added into the file
3685 lib/silcutil/silcutil.[ch].
3687 Added silc_string_regex_combine to combine to regex strings
3688 into one so that they can be used as one regex string by
3689 the GNU regex library. Added into the file
3690 lib/silcutil/silcutil.[ch].
3692 Added silc_string_regex_match to match two strings. It returns
3693 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3695 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Imported GNU regex to the soruce tree into lib/contrib.
3698 Fixed some compiler warning from the regex.c.
3700 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3702 * Fixed MOTD command in the server to work in router environment.
3704 * Fixed the MOTD command in the client library to support
3705 the server argument in the command.
3707 * Added `nickname_len' argument to the silc_idlist_add_client
3708 in the server, as the `nickname' argument may be binary data
3711 * Added silc_idlist_get_channels to return all channels from
3714 * Implemented LIST command to the server. Affected file is
3717 * Implemented the LIST command to the client library and on the
3720 * Added [<user count>] argument to the LIST command reply.
3721 With private channels the user count is not shown.
3723 * Updated TODO and README.
3725 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3727 * The client entry's data.registered must be TRUE even with
3728 global client entry on global client list. The data.registered
3729 is used to check whether the client is anymore in the network,
3730 for example with WHOWAS command so it must be valid.
3732 * Fixed the WHOWAS command in the server. It now actually works
3733 in router environment. Added function into silcd/command_reply.c
3734 silc_server_command_reply_whowas_save.
3736 * Added silc_idlist_purge function to the silcd/idlist.c
3737 to periodically purge the ID Cache.
3739 * Fixed INFO command in the server. It works now in router
3740 environment. Added <server name> argument to the INFO command
3741 reply. Updated the protocol specs.
3743 * Fixed minor bug in silc_idcache_purge to not purge if the
3744 expire value is zero.
3746 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3747 they were buggy because of the WHOWAS information.
3749 * Fixed local command MSG to handle the async resolving of
3750 the remote client properly. It used to fail the first MSG.
3751 Affected file silc/local_command.c.
3753 * Added `data_len' field to SilcIDCache context.
3755 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Update TODO. Todo in commands in the server.
3759 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3762 used by routers as broadcast packet to inform other routers
3763 about the changed user mode.
3765 Implemented the notify handling in the server. Affected file is
3766 silcd/packet_receive.c. Added the function
3767 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3769 * Added new generic Channel Payload and deprecated the New Channel
3770 Payload. The New Channel Payload is now the generic Channel
3773 * Added new argument `mode' to the silc_server_send_new_channel
3774 as it is required in the Channel Payload now.
3776 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3777 and created a new and real SilChannelPayload to represent the
3778 new generic Channel Payload. Implemented the encode/decode
3779 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3781 * Added silc_server_get_client_channel_list to return the list
3782 of channels the client has joined for WHOIS command reply.
3783 Affected file silcd/server.[ch].
3785 * Implemented the channel list sending in the WHOIS command reply
3786 in server and in the client.
3788 Implemented the channel list displaying on the user interface
3789 as well. Affected file silc/client_ops.c.
3791 * Added silc_channel_payload_parse_list to parse list of Channel
3792 Payloads. It returns SilcDList list of SilcChannelPayloads.
3793 Client for example can use this function to parse the list of
3794 channels it receives in the WHOIS command reply. The caller
3795 must free the list by calling silc_channel_payload_list_free.
3796 Affected files lib/silccore/silcchannel.[ch].
3798 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Added one new argument <user mode> to the WHOIS command reply
3801 to return the mode of the user in SILC. Updated the protocol
3804 Implemented it to the server and client.
3806 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Fixed the mode printing on the user interface on joining.
3809 Affected file silc/client_ops.c.
3811 * Implemented the UMODE command and user modes in general to the
3812 client library and to the user interface.
3814 * Implemented the UMODE command to the server.
3816 * The server now sends UNKNOWN_COMMAND error status if client sends
3817 unknown command. Affected file silcd/command.c.
3819 * All server commands now handle the command identifier the right
3820 way when sending the command reply to the client. The client can
3821 use to identify the command replies with the identifier.
3823 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Added silc_server_get_client_route to resolve the route to
3826 the client indicated by the client ID. Affected file is
3829 * Added silc_server_relay_packet as general function to relay
3830 packet to arbitrary destination. This deprecates functions
3831 like _send_private_message_key, _relay_notify etc. Affected
3832 file is silcd/packet_send.[ch].
3834 Removed silc_server_send_key_agreement,
3835 silc_server_send_private_message_key and
3836 silc_server_packet_relay_notify functions from the file
3837 silcd/packet_send.[ch].
3841 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3842 server. Affected file silcd/packet_receive.[ch].
3844 * Implemented the KILL command to the client. Implemented the
3845 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3846 Affected files lib/silcclient/command[_reply].c and
3847 lib/silcclient/client_notify.c. Implemented the KILL notify
3848 printing in the user inteface.
3850 * Fixed a lot silc_parse_nick memory leaks from the client
3851 library in the file lib/silcclient/command.c.
3853 * Changed the silc_server_send_notify_on_channels's `sender'
3854 argument from SilcSocketConnection to SilcClientEntry to
3855 check the sender as entry and not as connection object and not
3856 to send to the client provided as argument. The affected file
3857 is silcd/packet_send.[ch].
3859 * The notify packets that are destined directly to the client used
3860 to not to be processed by the server. Now changed that and the
3861 server processes all notify packets. After relaying the packet
3862 to the client the notify packet is processed in the server.
3864 * The silc_server_free_client_data now checks whether there is
3865 pending outgoing traffic for the client and purges the data to
3866 the network before removing the client entry.
3868 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3871 an client is killed from the SILC Network. Updated the protocol
3874 Added new function silc_server_send_notify_killed to the
3875 silcd/packet_send.[ch].
3877 * Added function silc_server_packet_relay_notify to relay notify
3878 packets that are destined directly to a client. In this case
3879 the server does not process the notify packets but merely relays
3880 it to the client. Affected file silcd/packet_send.[ch].
3882 Added also silc_server_packet_process_relay_notify to check
3883 whereto relay the notify. Affected file is
3884 silcd/packet_receive.[ch].
3886 * Implemented the KILL command to the server.
3890 * Added the backup schema desgined last fall to the protocol
3891 specs for everyone to see. The specification is in the
3892 *-spec-xx.txt draft and the packet type definitions for the
3893 backup routers is in *-pp-xx.txt draft. Thusly, added also
3894 new packet type SILC_PACKET_CELL_ROUTERS.
3896 * A big security problem in the implementation discovered. The
3897 signoff of an client did not cause new channel key generation
3898 which it of course should've done. The channel keys must be
3899 always re-generated when client leaves (or signoffs) the channel.
3900 The silc_server_remove_from_channels funtion now handles
3901 the channel key re-generation.
3903 * Added `sender' argument to the silc_server_send_notify_on_channels
3904 to not to send the client provided as argument. Affected file
3905 silcd/packet_send.[ch].
3907 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Implemented OPER and SILCOPER commands into the server and
3912 * Added silc_auth_verify and silc_auth_verify_data to verify
3913 the authentication directly from the authentication payload.
3914 It supports verifying both passphrase and public key based
3915 authentication. Affected file lib/silccore/silcauth.[ch].
3917 * Added `hash' field to the SilcIDListData structure. It is the
3918 hash negotiated in the SKE protocol. Affected file is
3921 * Slight redesigning of the SilcAuthPayload handling routines.
3922 Do not send SilcPKCS but SilcPublicKey as argument.
3924 * Implemented the public key authentication support to the
3925 serverconfig. The public key is loaded from the provided path
3926 and saved as authentication data to void * pointer. Thus,
3927 changed the unsigned char *auth_data to void *auth_data;
3929 * Fixed SHUTDOWN command to send the reply before the server
3930 is shutdown. :) Affected file silcd/command.c.
3932 * Fixed fatal bug in CONNECT command. The hostname was invalid
3933 memory and server crashed. Affected file silcd/command.c.
3935 * Fixed fatal bug in CLOSE command. The server_entry became
3936 invalid but was referenced later in the command. Affected file
3939 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Fixed fatal bug in failure packet handling. Server ignored
3942 the failure and thus crashed when it came.
3946 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3949 that the command may be executed only once in (about) 2 seconds.
3950 The old SILC_CF_LAG flag is same but allows command bursts up
3951 to five before limiting.
3953 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3954 server code. Various commands now includes the CF_LAG_STRICT
3955 flag to disallow any kind of miss-use of the command.
3957 * Fixed the silc_buffer_unformat to not to allocate any data
3958 if the length of the data is zero. It used to allocate the
3959 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3961 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Changed the format of AdminConnection configuration section
3964 in the server. Added username of the admin to the format.
3965 Affected files silcd/serverconfig.[ch].
3967 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3968 to return admin configuration data by host, username and/or
3971 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Implemented WHOWAS command to the server. Added the functions:
3975 silc_server_command_whowas_parse,
3976 silc_server_command_whowas_send_reply,
3977 silc_server_command_whowas_from_client and
3978 silc_server_command_whowas_from_server
3980 * Added <Client ID> argument to the WHOWAS command reply. Updated
3981 the protocol specs accordingly.
3983 * Implemented WHOWAS command and command_reply to the client
3986 Implemented the WHOWAS printing on the user interface.
3988 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Added new argument to the WHOWAS command reply, the real name.
3991 It is an optional argument. Updated the protocol specs.
3993 * Added SilcIDCacheDestructor callback that is registered when
3994 the SilcIDCache is allocated. The callback is called when
3995 an cache entry in the ID Cache expires, or is purged from the
3996 cache. Added into lib/silccore/idcache.[ch].
3998 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3999 to destruct the client entries when the cache entry expires.
4000 Other ID Cache's in server and in the client library ignores
4003 * If the ID Cache entry's `expire' field is zero then the entry
4004 never expires. Added boolean `expire' argument to the
4005 silc_idcache_add function in the lib/silccore/idcache.[ch].
4006 If it is TRUE the default expiry value is used.
4008 * Added silc_server_free_client_data_timeout that is registered
4009 when client disconnects. By default for 5 minutes we preserve
4010 the client entry for history - for WHOWAS command.
4012 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Added support to the server to enforce that commands are not
4015 executed more than once in 2 seconds. If server receives
4016 commands from client more frequently, timeout is registered
4017 to process the commands. Affected file silcd/command.c.
4018 Added new function silc_server_command_process_timeout.
4020 * Changed NICK_NOTIFY handling in client library to check that
4021 if the client's nickname was changed, so there is no need to
4022 resolve anything from the server.
4024 * Removed error printing from the WHOIS and IDENTIFY commands.
4025 If error occurs then it is ignored silently in the client library.
4026 The application, however, may map the received error to
4027 human readable error string. The application currently maps
4028 the NO_SUCH_NICKNAME error to string.
4030 * Made the command status message public to the application. Moved
4031 them from lib/silcclient/command_reply.c to
4032 lib/silcclient/command_reply.h. The application can map the
4033 received command status to the string with the
4034 silc_client_command_status_message function.
4036 * Added check to the server to check that client's ID is same
4037 as the Source ID in the packet the client sent. They must
4040 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added dist-bzip hook to the Makefile.am to make bzip2
4043 compressed distributions.
4045 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Server now enforces the maximum length for the nickname and
4048 the channel as protocol specification dictates. 128 bytes for
4049 nickname and 256 bytes for channel name.
4051 * Moved the WHOIS printing to the application. The client libary
4052 does not print out the WHOIS information anymore, the application
4053 must do it. Renamed silc_client_command_reply_whois_print to
4054 the silc_client_command_reply_whois_save.
4056 The client's idle time is also sent to the application now, and
4057 the idle is shown on screen.
4059 * Added silc_client_command_reply_identify_save to save the
4060 received IDENTIFY entries.
4062 * Do not check for channel private keys in message sending and
4063 reception if the channel does not have the PRIVKEY mode set.
4064 Affected file lib/silclient/client_channel.c.
4066 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4069 just surfaced after chaning the JOIN procedure.
4071 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Added silc_client_get_clients_by_list to get client entries
4074 from Client ID list, that is returned for example by JOIN
4075 and USERS command replies. The application should use this
4076 function for example when JOIN command reply is received to
4077 resolve the clients already on the channel (library does not
4078 do that anymore as USERS command reply is not used in the JOIN
4079 procedure anymore). Affected files lib/silcclient/silcapi.h and
4080 lib/silcclient/idlist.c.
4082 * JOIN command reply and USERS command reply returns now SilcBuffer
4083 pointers instead of unsigned char pointers when returning
4084 the client list and mode list.
4086 * Added <Client ID> argument to the JOIN command reply, mainly
4087 for the server to identify for which client the command was
4088 originally sent. Updated protocol specs accordingly.
4090 * Added SilcDlist private_key pointer to the SilcChannelEntry
4091 in the client to support the channel private keys. Affected
4092 file is lib/silcclient/idlist.h.
4094 * Added SilcChannelPrivateKey argument to the function
4095 silc_client_send_channel_message so that application can choose
4096 to use specific private ke if it wants to. If it is not provided,
4097 the normal channel key is used, unless private keys are set.
4098 In this case the first (key that was added first) is used
4099 as the encryption key.
4101 * Implemented the support for channel private key handling.
4102 Implemented the following functions:
4104 silc_client_add_channel_private_key,
4105 silc_client_del_channel_private_keys,
4106 silc_client_del_channel_private_key,
4107 silc_client_list_channel_private_keys and
4108 silc_client_free_channel_private_keys
4110 Affected file lib/silcclient/client_channel.c.
4112 * Added the support for the private keys in the channel message
4113 sending and encryption and in the message reception and
4114 decryption. Affected funtions are
4115 silc_client_send_channel_message and silc_client_channel_message.
4117 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Added SKE's key verify callback to the client library's
4120 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4122 * Removed the statement that server (or router) must send USERS
4123 command reply when joining to the channel so that the client
4124 knows who are on the channel. Instead, the client list and
4125 client's mode list is now sent in the JOIN command reply to the
4126 client who joined channel. This is better solution.
4128 * Added function silc_server_get_users_on_channel and function
4129 silc_server_save_users_on_channel to the silcd/server.[ch].
4131 * Removed function silc_server_command_send_users from the
4134 * Do not show topic on the client library anymore. The topic is
4135 sent in the command reply notify to the application and the
4136 application must show the topic now.
4138 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Added client searching by nickname hash into the IDENTIFY and
4141 WHOIS commands in the server as they were clearly missing from
4142 them. Affected file is silcd/command.c.
4144 * Fixed a bug in private message receiving in the client library.
4145 The remote ID was freed and it wasn't supposed, now it is
4148 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Minor fix to the channel payload; allocate the data area, as it
4151 needs to be of specific length.
4153 * If the key agreement port is zero then the operating
4154 system will define the bound port. Affected files are
4155 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4157 * Added new function silc_channel_payload_decrypt into the file
4158 lib/silccore/silcchannel.[ch].
4160 * Moved the channel message etc, check from silc_packet_decrypt
4161 to applications. The library calls now a generic
4162 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4163 when the packet is either normal or special. This was done to
4164 allow more wide range of checking that was not allowed when
4165 the code was in library. Now applications can do virtually any
4166 checks to the packet and return to the library the decision how
4167 the packet should be processed. Affected files are
4168 lib/silccore/silcpacket.[ch].
4170 Added silc_server_packet_decrypt_check to the server and
4171 silc_client_packet_decrypt_check to the client library.
4173 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4174 to send with specified source and destination information.
4176 * Channel message delivery between routers was broken after the
4177 channel key distribution was fixed earlier. The channel key
4178 was used be to distributed to other routers as well which is not
4179 allowed by the protocol. Now this is fixed and channel keys
4180 really are cell specific and the channel message delivery between
4181 routers comply with the protocol specification.
4183 * Fixed various commands in server to check also the global list
4184 for the channel entry and not just the local list. The affected
4185 file silcd/command.c.
4187 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Added assert()s to buffer formatting and unformatting routines
4190 to assert (if --enable-debug) when error occurs. Affected
4191 file: lib/silcutil/silcbuffmt.c.
4193 * Changed to auto-reconnect to check whether the remote host is
4194 router and register the re-connect timeout if it is. It used
4195 to check that whether we are normal server, but router must do
4196 auto-reconnect with another router as well. Affected file
4199 * Removed the [<key len>] option from CMODE command as the cipher
4200 name decides the key length, nowadays. See the defined ciphers
4201 from the protocol specification.
4203 * Added [<hmac>] option to the CMODE command to define the HMAC
4204 for the channel. Added SILC_CMODE_HMAC channel mode.
4206 * Added [<hmac>] option for the JOIN command so that user can
4207 select which HMAC is used to compute the MACs of the channel
4210 * Added Hmac field to the Channel Message Payload. The integrity
4211 of plaintext channel messages are now protected by computing
4212 MAC of the message and attaching the MAC to the payload. The
4213 MAC is encrypted. Now, it is clear that this causes some
4214 overhead to the size of the packet but rationale for this is that
4215 now the receiver can verify whether the channel message decrypted
4216 correctly and also when private keys are set for the channel the
4217 receiver can decrypt the packet with several keys and check from
4218 the MAC which key decrypted the message correctly.
4220 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4221 lib/silccrypt/silccipher.[ch].
4223 * Added silc_hash_len to return the digest length into the
4224 lib/silcrypt/silchash.[ch].
4226 * Rewrote parts of Silc Channel Payload interface in the
4227 lib/silccore/silcchannel.[ch]. The encode function now also
4228 encrypts the packet and parse function decrypts it.
4230 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Fixed a minor formatting bug in the SKE's key material processing.
4233 It actually might have processed the keys wrong way resulting
4236 * Redefined the mandatory HMAC algorithms and added new algorithms.
4237 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4238 and hmac-md5 truncated to 96 bits. The mandatory is now
4239 hmac-sha1-96. Rest are optional (including the one that used
4240 to be mandatory). Rationale for this is that the truncated HMAC
4241 length is sufficient from security point of view and can actually
4242 make the attack against the HMAC harder. Also, the truncated
4243 HMAC causes less overhead to the packets. See the RFC2104 for
4246 * Added new [hmac] configuration section. The SKE used to use
4247 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4248 is of course wrong. The official names that must be proposed in
4249 the SKE are the ones defined in the protocol specification
4250 (hmac-sha1-96 for example). The user can configure any hmac
4251 using any hash function configured in the [hash] section. At
4252 least, the mandatory must be configured.
4254 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4256 * Added HMAC list to the SKE proposal list. It has now both
4257 hash algorithm list and HMAC list. This makes the protocol
4258 incompatible with previous versions. The SKE now seems to work
4259 the way it is supposed to work, for the first time actually.
4261 * Defined plain Hash algorithms to the protocol specification.
4264 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Implemented support for key agreement packets into the server.
4267 Added functions silc_server_key_agreement and
4268 silc_server_send_key_agreement. Other than these functions,
4269 server has nothing to do with this packet.
4271 * Added support for private message key packets into the server.
4272 Added functions silc_server_private_message_key and
4273 silc_server_send_private_message_key.
4277 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4278 called in the protocol's final callback instead in the END
4279 protocol state. This makes a little more sense and in the same
4280 time in client we can use the same protocol routines for normal
4281 key exchange and to key agreement packet handling as well.
4283 * Added to both client's and server's KE protocol context the
4284 SilcSKEKeyMaterial pointer to save the key material. We will
4285 bring the key material to the protocol's final callback by doing
4286 this. The final callback must free the key material.
4288 * Added SKE's packet_send callback into client's KE protocol
4289 context so that the caller can choose what packet sending function
4290 is used. This way we can use different packet sending when
4291 doing normal SKE when doing key agreement packet handling (in
4292 the key agreement packet handling we do not want to encrypt
4295 * Implemented the responder side of the key agreement routines
4296 in the client. The client can now bind to specified port and
4297 accept incoming key negotiation. The key material is passed
4298 to the application after the protocol is over.
4300 * Implemented the processing of incoming Key Agreement packet
4301 in the client. Added function silc_client_key_agreement to
4304 * Implemented the intiator side of the key agreement routines
4305 in the client. The client can now initiate key agreement with
4306 another remote client. The key material is passed to the
4307 application after the protocol is over.
4309 * Created client_keyagr.c to include all the key agreement
4312 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4313 SILC_TASK_CALLBACK except that it is not static.
4315 * Created client_notify.c and moved the Notify packet handling
4316 from the client.[ch] into that file.
4318 * Created client_prvmsg.c and moved all private message and
4319 private message key routines from the client.[ch] into that file.
4321 * Create client_channel.c and moved all channel message and
4322 channel private key routines from the client.[ch] into that file.
4324 * Changed silc_client_get_client_by_id_resolve to resolve with
4325 WHOIS command instead of IDENTIFY command, in the file
4326 lib/silclient/idlist.c.
4328 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Implemented the SKE's responder side to the Client library.
4332 * When FAILURE is received to the protocol do not trust it
4333 blindly. Register a timeout to wait whether the remote closes
4334 the connection as it should do it, only after that process the
4335 actual failure. This was changed to both client and server.
4337 * Added client_internal.h to include some of the structures
4338 there instead of client.h in lib/silcclient/.
4340 * Added function silc_task_unregister_by_callback to unregister
4341 timeouts by the callback function.
4343 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Some "Incomplete WHOIS info" errors has been appearing on the
4346 log files. Took away the entry->userinfo check from WHOIS
4347 reply sending. The entry->userinfo is now " " if client did not
4348 provide one. I thought this was fixed earlier but something
4349 is wrong still. Let's see if the error still appears.
4351 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Fixed a minor bug in the login when the channel key is
4354 re-generated in the server. It used to generate the key in
4355 wrong order and thus caused problems in the channel traffic.
4357 * Fixed a minor bug in channel key distsribution after
4358 KICK command. The key was not sent to the router even though
4361 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Added silc_ske_process_key_material_data as generic routine
4364 to process any key material as the SILC protocol dictates. The
4365 function is used by the actual SKE library but can be used by
4366 applications as well. This relates to the private message keys
4367 and the channel private keys since they must be processed the
4368 same way the normal SILC session keys. The protocol dictates
4369 this. Affected files: lib/silcske/silcske.[ch].
4371 Added also silc_ske_free_key_material to free the
4372 SilcSKEKeyMaterial structure.
4374 * Defined silc_cipher_set_key function to set the key for
4375 cipher without using the object's method function. The affected
4376 files: lib/silccrypt/silccipher.[ch].
4378 * Implemented silc silc_client_add_private_message_key,
4379 silc_client_add_private_message_key_ske,
4380 silc_client_del_private_message_key,
4381 silc_client_list_private_message_keys and
4382 silc_client_free_private_message_keys functions in the
4385 Added functions silc_client_send_private_message_key to send
4386 the Private Message Key payload and silc_client_private_message_key
4387 to handle incoming Private Message Key payload.
4389 * Added Cipher field to the Private Message Key payload to set
4390 the cipher to be used. If ignored, the default cipher defined
4391 in the SILC protocol (aes-256-cbc) is used.
4393 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Removed lib/silcclient/ops.h file.
4397 Redefined parts of the SILC Client Library API. Created new
4398 file silcapi.h that deprecates the ops.h file and defines the
4399 published Client Library API. Defined also private message key
4400 API and channel private key API into the file.
4402 This is the file that the application must include from the
4403 SILC Client Library. Other files need not be included by
4404 the application anymore.
4406 * Added new key_agreement client operation callback and also
4407 defined the Key Agreement library API for the application.
4409 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4411 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4412 is used by clients to request key negotiation between another
4413 client in the SILC network. If the negotiation is started it
4414 is performed using the SKE protocol. The result of the
4415 negotiation, the secret key material, can be used for example
4416 as private message key.
4418 Implemented the Key Agreement payload into the files
4419 lib/silccore/silauth.[ch].
4421 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Redefined ciphers for the SILC protocol. Added some new ciphers
4424 and defined the key lengths for the algorithms. Changed the
4425 code accordingly. The default key length is now 256 bits.
4427 * Fixed SKE key distribution function silc_ske_process_key_material
4428 when the key length is more than 128 bits. The default key
4429 length in SILC is now 256 bits.
4431 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4432 to indicate unsupported algorithm.
4434 * Renamed rijndael.c to aes.c and all functions as well.
4436 * Fixed a long standing channel key setting bug in client library.
4437 Weird that it has never surfaced before.
4439 * Fixed bug in channel deletion. If the entire channel is removed
4440 then it must also delete the references of the channel entry
4441 from the client's channel list as the client's channel entry and
4442 the channel's client entry share same memory.
4444 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Implemented CONNECT and SHUTDOWN commands in the client.
4448 * Implemented CLOSE command to the client.
4450 * Added the function silc_idlist_find_server_by_name into the
4451 files silcd/idlist.[ch].
4453 Added the function silc_idlist_find_server_by_conn into the
4454 files silcd/idlist.[ch].
4456 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * DIE command was renamed to SHUTDOWN. Updated the both code
4461 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4462 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4464 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4467 * Added function silc_server_create_connection function to create
4468 connection to remote router. My server implementation actually
4469 does not allow router to connect to normal server (it expects
4470 that normal server always initiates the connection to the router)
4471 so the CONNECT command is only good for connecting to another
4474 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4477 or some other client was kicked from the channel.
4479 Implemented the handling of the notify type to both client
4482 Implemented silc_server_send_notify_kicked to send the KICKED
4483 notify. It is used to send it to the server's primary router.
4485 * Implemented the KICK command into server and client.
4487 * Added `query' argument to the silc_idlist_get_client function
4488 to indicate whether to query the client from server or not if
4491 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4492 to indicate that the client is not channel founder.
4496 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Removed the rng context from SilcPacketContext structure and
4499 changed that the packet routine uses the Global RNG API.
4501 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Added support for quit message that client can "leave" on the
4504 channel when it quits the SILC. It is ditributed inside the
4505 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4507 Added silc_server_free_client_data that will take the
4508 signoff message as argument.
4510 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4512 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Updated parts of the protocol specification to keep it up
4517 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4520 payloads in one packet.
4522 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4523 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4524 use now the new List flag.
4526 * Also deprecated the following packet types: REPLACE_ID,
4527 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4529 * Added list support for Notify packet in server.
4531 * Added silc_server_send_notify_channel_change to send the
4532 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4533 the silc_server_send_replace_id.
4535 * Added silc_server_send_notify_nick_change to send the
4536 NICK_CHANGE notify type. Deprecates the function
4537 silc_server_send_replace_id.
4539 * Added silc_server_send_notify_join to send the JOIN notify type.
4540 Deprecates the function silc_server_send_new_channel_user.
4542 * Added silc_server_send_notify_leave to send LEAVE notify type.
4543 Deprecates the function silc_server_send_remove_channel_user.
4545 * Added silc_server_send_notify_cmode and
4546 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4547 types. Deprecates the silc_server_send_set_mode function.
4549 * Added SERVER_SIGNOFF notify type to indicate that server has
4550 quit. This means that all clients on the channel from that
4551 server will drop. This can be also used when netsplit happens.
4553 Deprecated REMOVE_ID packet type since it is not needed anymore
4556 Added silc_server_send_notify_server_signoff to send the
4557 SERVER_SIGNOFF notify type. Deprecates the function
4558 silc_server_send_remove_id.
4560 Added also silc_server_send_notify_signoff to send the
4561 SIGNOFF notify type.
4563 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4564 SILC protocol from this day on. Changed the protocol
4565 specification as well.
4567 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4568 notify type. It is used between routers to notify about
4569 topic changes on a channel.
4571 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4574 * Partly updated the protocol specification to comply with the
4575 changes now made. It is still though a bit outdated.
4577 * The JOIN notify type now takes one extra argument <Channel ID>.
4578 The packet used to be destined to the channel but now the
4579 JOIN type may be sent as list thus it is impossible to
4580 destine it to any specific channel. By adding this argument
4581 it is again possible.
4583 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added CREDITS file. The CHANGES and CREDITS file will appear
4586 in the distribution as well.
4588 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4591 types in the server's silcd/packet_receive.c.
4593 * Implemented CMODE and CUMODE to work in router environment.
4595 * Fixed minor encoding and decoding buglet from the
4596 lib/silccore/silcmode.c.
4598 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4601 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4603 * Changed all SilcConfigServer* and silc_config_server* to
4604 SilcServerConfig* and silc_server_config*, respectively.
4607 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4609 * Associated the ID (client or server ID) to the Authentication
4610 Payload to avoid any possibility of forging. Updated the
4611 protocol specification and the code accordingly.
4613 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * The RSA key length is now save to the RsaKey context in the
4616 key generation process in lib/silccrypt/rsa.c. The key length
4617 is now used to figure out the maximum size of the block allowed
4618 to be encrypted/signed.
4620 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4621 is equivalent to the silc_mp_mp2bin but does not allocate any
4624 * Changed silc_mp_mp2bin API to take length argument. If it is
4625 non-zero then the buffer is allocated that large. If zero, then
4626 the size is approximated using silc_mp_sizeinbase, which however
4629 * Created Global RNG API which is global RNG that application can
4630 initialize. After initializing, any routine anywhere in the
4631 code (including library) can use RNG without allocating a new
4632 RNG object. This was done to allow this sort of use of the
4633 RNG in code that has no chance to allocate RNG object. All
4634 applications currently allocate this and many routines in the
4635 library use this. Affected file lib/silccrypt/silcrng.[ch].
4637 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4638 it to use the Global RNG API.
4640 * Defined Authentication Payload into protocol specification that
4641 is used during SILC session to authenticate entities. It is
4642 used for example by client to authenticate itself to the server
4643 to obtain server operator privileges.
4645 Implemented this payload into the lib/silccore/silcauth.[ch].
4646 Implemented also routines for public key based authentication
4647 as the new protocol specification dictates.
4649 Moved definitions of different authentication methods from
4650 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4652 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4653 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4654 silc_pkcs_verify_with_hash functions into the file
4655 lib/silccrypt/silcpkcs.[ch].
4657 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4659 * The client entry's userinfo pointer must be always valid.
4660 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4661 will fail since it requires the userinfo. Now, the userinfo
4662 is allocated as "" if actual userinfo does not exist. Actually,
4663 it must exist and it is totally Ok to drop client connections
4664 that does not announce the userinfo. However, we will make
4665 this workaround for now.
4667 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4668 to return the remote port by socket.
4670 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4673 SILC_SERVER_PENDING_EXEC and added an new macro
4674 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4675 data or when error occurs while processing the pending command.
4677 Added new argument `destructor' into silc_server_command_pending
4678 and to the SilcServerCommandPending object. This destructor is
4679 now called after calling the pending callback or if error occurs
4680 immediately. If error occurs the actual pending callback won't
4681 be called at all - only the destructor. The destructor may be
4682 NULL if destructor is not needed.
4684 All this applies for client library code as well. Similar
4685 changes were made there as well for the pending commands.
4687 In the client, the application must now allocate the
4688 SilcClientCommandContext with the silc_client_command_alloc
4691 * Added reference counter to the SilcServerCommandContext. Added
4692 function silc_server_command_alloc and silc_server_command_dup
4695 Same type of functions added to the client library for the same
4698 * Removed the cmd_ident from IDListData away since it is now
4699 global for all connections. It is the command identifier used
4700 in command sending and with pending commands. The affected file
4703 * Added reference counter to the SilcSocketConnection objecet to
4704 indicate the usage count of the object. The object won't be
4705 freed untill the reference counter hits zero. Currently only
4706 server uses this, and client ignores it. The client must be
4707 set to use this too later. The affected files are
4708 lib/silccore/silcsockconn.[ch]. Added also the function
4709 silc_socket_dup to increase the reference counter.
4711 This was mainly added because it is possible that the socket
4712 is removed underneath of pending command or other async
4713 operation. Now it won't be free'd and proper DISCONNECTING
4714 flags, etc. can be set to avoid sending data to connection that
4715 is not valid anymore.
4717 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4718 the connection. After that it sets SILC_SET_DISCONNECTED.
4719 It is, however, possible that the socket data is not still freed.
4720 The silc_server_packet_process now checks that data is not
4721 read or written to connection that is DISCONNECTED. The socket
4722 get's freed when the reference counter hits zero.
4724 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Changed the client operation API: channel_message operation's
4727 `sender' is now the client entry of the sender, not the nickname
4728 and the `channel' is the channel entry, not the channel name.
4730 In the private_message operation the `sender' is now also the
4731 client entry of the sender not the nickname.
4733 Affected file is lib/silcclient/ops.h and all applications
4734 using the client operations.
4736 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Moved the calling of ops->connect() from connect_to_server_final
4739 into receive_new_id functin since that is the point when the
4740 client is actually allowed to send traffic to network. The
4741 affected file is lib/silcclient/client.c.
4743 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4746 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4747 (if needs broadcasting) instead of broadcasting the packets one
4748 by one which would make a burst in the network traffic.
4750 * Added `broadcast' argument to the functions in silcd/server.[ch]
4751 silc_server_create_new_channel[_with_id] to indicate whether
4752 to send New Channel packet to primary router.
4754 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Added new function into the silcd/server.[ch] files:
4757 silc_server_create_new_channel_with_id to create new channel with
4758 already existing Channel ID.
4760 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4761 lib/silccore/silcpacket.h. This packet is used t send list of
4762 Set Mode payloads inside one packet. Server uses this to set
4763 the modes for the channels and clients on those channels, that it
4764 announced to the router when it connected to it. The protocol
4765 specification has been updated accordingly.
4767 * The silc_server_new_channel did not handle the packet coming
4768 from normal server as it normally does not send that. However,
4769 when it announces its channels it does send it. Implemented
4770 the support for that.
4772 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4773 into the file lib/silccore/id.h.
4775 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Fixed memory leaks in the functions silc_idlist_del_client,
4778 silc_idlist_del_channel and silc_idlist_del_server in the file
4779 silcd/idlist.c. All of those leaked like a sieve.
4781 * Fixed some small memory leaks in the client's function
4782 silc_client_notify_by_server.
4784 * Added functions into silcd/server.c: silc_server_announce_clients,
4785 silc_server_announce_channels and silc_server_announce_server.
4786 These functions are used by normal and router server to announce
4787 to its primary router about clients, channels and servers (when
4788 router) that we own. This is done after we've connected to the
4791 These functions effectively implements the following packet types:
4792 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4793 and SILC_PACKET_NEW_ID_LIST.
4795 * Added new functions into the silcd/packet_receive.[ch]:
4796 silc_server_new_id_list, silc_server_new_channel_list and
4797 silc_server_new_channel_user_list to handle the incoming
4798 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4800 * Added support of changing Channel ID in the function
4801 silc_server_replace_id. If the server that announces a channel
4802 to the router already exists in the router (with same name but
4803 with different Channel ID), router is responsible to send
4804 Replace ID packet to the server and force the server to change
4805 the Channel ID to the one router has.
4807 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4808 client that the Channel ID has been changed by the router. The
4809 normal server sends this to the client. Client must start using
4810 the new Channel ID as the channel's ID.
4812 Implemented handling of this new type into lib/silcclient/client.c
4813 into the function silc_client_notify_by_server.
4815 * Added new function silc_idlist_replace_channel_id into the files
4816 silcd/idlist.[ch] to replace the Channel ID.
4818 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Call silc_server_command_identify_check always when processing
4821 the IDENTIFY command in silcd/command.c
4823 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4826 send keepalive packets. The packet can be sent by clients,
4827 servers and routers.
4829 Added function silc_socket_set_heartbeat into the file
4830 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4831 If not set, the heartbeat is not performed. The actual
4832 heartbeat is implemented in the low level socket connection
4833 library. However, application is responsible of actually
4836 Added silc_server_send_heartbeat to send the actual heartbeat
4837 packet into silcd/packet_send.[ch]. Server now performs
4838 keepalive with all connections.
4840 * Added silc_task_get_first function into lib/silcutil/silctask.c
4841 to return the timeout task with shortest timeout. There was a bug
4842 in task unregistration that caused problems. TODO has been
4843 updated to include that task system must be rewritten.
4845 * The client library will now resolve the client information when
4846 receiving JOIN notify from server for client that we know but
4847 have incomplete information.
4849 * Rewrote parts of silc_server_remove_from_channels and
4850 silc_server_remove_from_one_channel as they did not remove the
4851 channel in some circumstances even though they should've.
4853 * Encryption problem encountered in server:
4855 The LEAVE command used to send the Channel Key packet to the
4856 router immediately after generating it. However, the code
4857 had earlier sent Remove Channel user packet but not immediately,
4858 ie. it was put to queue. The order of packets in the router
4859 was that Channel Key packet was first and Remove Channel User
4860 packet was second, even though they were encrypted in the
4861 reverse order. For this reason, MAC check failed. Now, this
4862 is fixed by not sending the Channel Key packet immediately but
4863 putting it to queue. However, this is more fundamental problem:
4864 packets that are in queue should actually not be encrypted
4865 because packets that are sent immediately gets encrypted
4866 actually with wrong IV (and thus MAC check fails). So, packets
4867 that are in queue should be encrypted when they are sent to
4868 the wire and not when they put to the queue.
4870 However, the problem is that the current system has not been
4871 designed to work that way. Instead, the packet is encrypted
4872 as soon as possible and left to the queue. The queue is then
4873 just purged into wire. There won't be any fixes for this
4874 any time soon. So, the current semantic for packet sending
4877 o If you send packet to remote host and do not force the send
4878 (the packet will be in queue) then all subsequent packets to the
4879 same remote host must also be put to the queue. Only after the
4880 queue has been purged is it safe again to force the packet
4883 o If you send all packets immediately then it safe to send
4884 any of subsequent packets through the queue, however, after
4885 the first packet is put to queue then any subsequent packets
4886 must also be put to the queue.
4888 Follow these rules and everything works fine.
4890 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added new function silc_server_remove_clients_by_server to
4893 remove all client entries from ID list when the server connection
4894 is lost. In this case it is also important to invalidate all
4895 client entires as they hold the invalid server entry. This
4896 fixes fatal bug when server has lost connection and will reconnect
4899 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Made some sanity checks to silc_server_daemonise like to check
4902 whether the requested user and group actually exists.
4904 * Added sanity check to SKE's silc_ske_responder_finish to check
4905 that the public and private key actually is valid.
4907 * Invalidate the client's nickname when receiving Replace ID
4908 packet and the Client ID is being replaced. This means that the
4909 server will query the nickname if someone needs it (client)
4912 * Sort the ID Cache in client library when the ID Cache data
4913 has changed (needs sorting).
4915 * Do not allow for SILC client to create several connections to
4916 several servers. The client does not support windows right now
4917 and generating multiple connections causes weird behaviour.
4919 Irssi-silc client does support windows and can handle several
4920 connections without problems, see: www.irssi.org and SILC plugin.
4922 * Fixed some places where client was added to the IDList. The
4923 rule of thumb is following (in order to get everything right):
4924 If the client is directly connected local client then the
4925 `connection' argument must be set and `router' argument must be
4926 NULL to silc_idlist_add_client function. If the client is not
4927 directly connected client then the `router' argument must
4928 bet set and the `connection' argument must be NULL to the
4929 silc_idlist_add_client function.
4931 * The funtion silc_server_packet_send_local_channel actually did
4932 not check whether the client was locally connected or not. It
4933 does that now. Fixed a bug related to LEAVE command.
4935 * Fixed Remove Channel User payload parsing bug in server's
4936 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4938 * The server's silc_server_save_channel_key now checks also the
4939 global ID list for the channel as it might not be in the local
4940 list. Fixed a bug related to LEAVE command.
4942 * Is this the end of the [<unknown>] buglet that has been lurking
4943 around for a long time? A little for loop fix in server's
4944 silc_server_command_whois_parse that is used by both IDENTIFY
4945 and WHOIS command. At least, this was a clear bug and a cause
4946 of one type of [<unknown>] buglet.
4948 * WHOIS and IDENTIFY commands call the function
4949 silc_server_command_[whois/identify]_check function even if
4950 we are not router server.
4952 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Added --with-gmp configuration option. If set the GMP
4955 is always compiled in the SILC source tree. If not set then
4956 it is checked whether the system has the GMP3 installed. If
4957 it has then the GMP won't be compiled (the system's headers
4958 and library is used), if it doesn't have it then the GMP is
4959 compiled in the SILC source tree.
4961 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Changed RSA private exponent generation to what PKCS #1
4964 suggests. We try to find the smallest possible d by doing
4965 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4966 not security fix but optimization.
4968 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Added new config entry [Identity] to fork the server and run
4971 it as specific user and group. A patch from Bostik.
4973 * Imported Dotconf configuration library into lib/dotconf.
4974 This will be used to create the SILC configuration files later.
4975 It will appear in the distsribution after this commit.
4977 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * A big code auditing weekend happening. Auditing code for
4980 obvious mistakes, bugs and errors. Also, removing any code
4983 Removed files for being obsolete:
4985 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4986 inline in the file lib/silcutil/silcbuffer.h)
4988 o lib/silcutil/silcbufutil.c (the header has inline versions)
4990 Changed code to fix possible error conditions:
4992 o The buffer formatting routines now check that the destination
4993 buffer really has enough space to add the data. This applies for
4994 both buffer formatting and unformatting
4995 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4996 unformatting was changed to accomodate following rules:
4997 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4998 sent to the function while XXX_*STRING will not allocate or copy
4999 the data into the buffer. Instead it sets the pointer from the
5000 buffer into the pointer sent as argument (XXX_*STRING used to
5001 require that the pointer must be allocated already). This change
5002 makes this whole thing a bit more consistent and more optimized
5003 (note that the data returned in the unformatting with XXX_*STRING
5004 must not be freed now). The routines return now -1 on error.
5006 o Tried to find all code that use buffer_format and buffer_unformat
5007 and added return value checking to prevent formatting and
5008 especially unformatting errors and possible subsequent fatal
5011 o Changed ske->x and ske->KEY to mallocated pointers in
5012 lib/silcske/silcske.h. Fixed possible data and memory leak.
5014 o Added return value checking to all *_parse* functions. Fixed
5015 many memory leaks as well.
5017 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5018 so that buffer overflows would not happen. All code now also
5019 checks the return value as it can fail.
5021 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Added reconnection support to server if the normal server looses
5024 its connection to the router (for example if router is rebooted).
5025 The server performs normal reconnection strategy implemented
5026 to the server. Affected file silcd/server.c.
5028 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added new packet type SILC_PACKET_SET_MODE that is used to
5031 distribute the information about changed modes (for clients,
5032 channels and clients channel modes) to all routers in the
5033 network. Updated the protocol specification accordingly.
5035 Added functions into silcd/packet_send.c and
5036 silcd/packet_receive.c: silc_server_send_set_mode,
5037 silc_server_set_mode.
5039 Added new files silcmode.[ch] into lib/silccore that implements
5040 the encoding and decoding of Set Mode Payload. Added new type
5041 SilcSetModePayload. Moved the definitions of different modes
5042 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5044 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Oops, a little mistake in server's connection authentication
5047 protocol. The protocol is not ended with FAILURE but with
5048 SUCCESS if the authentication is Ok. :) Affected file is
5051 * Implemented NICK_CHANGE notify handling in server in the file
5052 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5053 the local clients on the channel. After the changing nickname
5054 in router environment snhould work and the [<unknown>] nickname
5055 should appear no more.
5057 The silc_server_replace_id function that receives the Replace ID
5058 payload now sends the NICK_CHANGE notify type also in the file
5059 silcd/packet_receive.c
5061 * Changed WHOIS and IDENTIFY command to support the maximum amount
5062 of arguments defined in protocol specs (3328 arguments). This
5063 fixed a bug that caused problems when there were more than three
5066 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Added extra parameter, command identifier, to the
5069 silc_client_send_command so that explicit command identifier
5072 Changed that ID list routines uses specific command identifier
5073 when sending WHOIS/IDENTIFY requests to the server so that they
5074 can be identified when the reply comes back.
5076 Affected files lib/silcclient/command.[ch],
5077 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5079 * Added `sender' argument to silc_server_packet_send_to_channel
5080 to indicaet the sender who originally sent the packet to us
5081 that we are now re-sending. Ignored if NULL. Affected file
5082 silcd/packet_send.[ch].
5084 * Added some server statistics support in silcd/server_internal.h
5085 SilcServerStatistics structure and around the server code. Also
5086 send some nice statistics information when client is connecting
5089 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Fixed channel ID decoding in server's JOIN command reply in
5092 silcd/command_reply.c
5094 * Fixed braodcasting of replace ID payload to not to send it if
5095 we are standalone server in silcd/packet_receive.c.
5097 * Fixed all channel message sending routines to not to send
5098 packets to clients that has router set, since they are routed
5099 separately in the same function earlier. Affects file
5100 silcd/packet_send.c and all channel packet sending functions.
5102 * In USERS reply, res_argv[i] are not allocated, the table
5103 is allocated. Thus changed that free the table, not its
5106 * In server's whois_check and identify_check if the client is
5107 locally connected do not send any WHOIS commands - they are not
5110 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Fixed some minor bugs in client when sending WHOIS command. The
5113 arguments was in wrong order.
5115 * Removed statis function add_to_channel from server in
5116 silcd/command.c that was previously used with the joining but
5119 * Tested USERS command in router environment successfully with two
5120 routers, two servers and two clients.
5122 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Reorganized the USERS command and command reply in client library
5125 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5126 When the command is given by user we register a pending command
5127 callback that will reprocess the command after the reply has been
5128 received from the server. When reprocessing the packet we then
5129 display the information. Thus, the USERS information is displayed
5130 now in the command callback instead of in the command reply
5131 callback. The processing of the command is same as previously
5132 when server has sent the command reply in the JOINing process.
5134 * Added to USERS command in silcd/command_reply.c to join the client,
5135 we didn't use to know about, to the channel after we've created
5136 a client entry for it. Also, for clienet we did know already still
5137 check whether it is on the channel or not and add it if not.
5139 * Removed silc_server_command_join_notify as the function and its
5142 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Changed the client's pending command handling to the same as the
5145 server's pending command handling. It is also now possible to
5146 execute command reply functions from other command reply
5147 function as the function callbacks for commands and command
5148 replies are one and same. The pending commands are not static
5149 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5150 in client connection context. Thus, pending commands are server
5151 connection specific as it is convenient.
5153 Changed the function silc_client_command_pending and
5154 silc_client_command_pending_del and added new function
5155 silc_client_command_pending_check. Removed the
5156 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5159 * Added cmd_ident, current command identifier, to the client
5160 connection context in lib/silcclient/client.h to keep track on
5161 command identifiers used in command sending. Client's command reply
5162 function handling now supports the mandatory command identifiers.
5164 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5165 funtions in client to fully support pending command callbacks.
5167 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5168 as one of the arguments to the application in the command reply
5171 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5172 before first releasing SILC but came back. Now it is removed again
5173 and should come back nomore. The FORWARDED flag was used only
5174 by the JOINing procedure by forwarding the command packet to router.
5175 Now, the JOINing procedure has been changed to more generic (due
5176 to various router environment issues) and FORWARDED is not needed
5177 anymore for anything. The protocol specification is yet to be
5180 Now, removed silc_server_packet_forward from server and the flag
5181 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5183 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Renamed NAMES command to USERS command. The NAMES was named that
5186 due to historical reasons. Now it is renamed. Also, rewrote
5187 parts of the USERS command. The nickname list is not sent anymore
5188 by the server. Only Client ID and mode lists are sent in the USERS
5189 command. Changed this also to the protocol specification.
5191 The client now resolves the names and stuff after it receives
5192 the USERS list from the server when joining to the channel.
5194 * WHOIS and IDENTIFY commands has been changed to support multiple
5195 Client ID's per command. One can now search for multiple users
5196 in the network by sending only one WHOIS or IDENTIFY command.
5197 Changed the code and the protocol specifications.
5199 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5200 uses silc_server_command_whois_parse to parse the request. */
5202 * If normal server, do not parse the WHOIS and IDENTIFY requests
5203 before sending it to the router. Saves some time.
5205 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Fixed JOIN command on client library. Wrong number of arguments
5208 used to crash the client.
5210 * Added silc_server_channel_has_global function to check whether
5211 channel has global users or not.
5213 * Added silc_server_channel_has_local function to check whether channel
5214 has locally connected clients on the channel.
5216 * The silc_server_remove_from_one_channel now checks whether the
5217 channel has global users or not after given client was removed from
5218 the channel. It also checks whether the channel has local clients
5219 on the channel anymore. If it does not have then the channel entry
5220 is removed as it is not needed anymore.
5222 * The silc_server_notify now checks on JOIN notify whether the joining
5223 client is one of locally connected or global. If it is global then
5224 the channel has now global users on the channel and that is marked
5225 to the channel entry. Also, it now saves the global client to
5226 global list who is joining and JOINs it to the channel. This is
5227 for normal server, that is.
5229 Changed silc_server_send_notify_on_channel,
5230 silc_server_packet_relay_to_channel and
5231 silc_server_packet_send_to_channel check if we are normal server
5232 and client has router set (ie. global client) do not send the
5233 message to that client, as it is already routed to our router.
5235 * Implemented LEAVE notify type handling in silc_server_notify
5238 * Tested LEAVE command in router environment successfully. Tested
5239 with two routers, two servers and two clients.
5243 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5245 * Implemented SIGNOFF notify type handling in silc_server_notify
5248 * silc_server_remove_id now removes the client entry from all channels
5249 it has joined and thusly sends SIGNOFF notify type.
5251 * Rewrote the NAMES list generation in server by removing two excess
5252 loops. The lists are created now inside one loop.
5254 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * silc_server_remove_channel_user checks now also global list
5257 for channel and client.
5259 * silc_server_new_channel_user checks now both local and global
5260 list for channel and client. Fixed a bug in client id decoding.
5261 Used to decode wrong buffer.
5263 * silc_server_channel_message checks now both local and global
5264 list for channel entry.
5266 * Tested channel joining (hence JOIN) in router environment
5267 successfully. Tested with two routers, two servers and two
5270 * Tested channel message sending in router environment successfully.
5272 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Added silc_server_save_channel_key into server.[ch] to save the
5275 received channel key in Channel Key payload processing. It is
5276 also used in JOIN command reply handling.
5278 Equivalent function silc_client_save_channel_key added into
5279 client.[ch] into client library.
5281 * Changed JOIN command reply to send information whether the channel
5282 was created or not (is existing already) and the channel key
5283 payload. Changed protocol specs accordingly.
5285 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5286 the request was sent by ID and not by nickname. Crashed on
5289 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5292 now correctly save the received data.
5294 * silc_server_free_sock_user_data now notifies routers in the
5295 network about entities leaving the network.
5297 At the same time implemented functions silc_server_remove_id
5298 and silc_server_send_remove_id to receive and send REMOVE_ID
5299 packets. The packet is used to notify routers in the network
5300 about leaving entities. The ID removed will become invalid in
5303 * Added function silc_idlist_del_server into server. Removes and
5304 free's server entry from ID list.
5306 * silc_server_private_message function now checks, if we are router,
5307 that the destination ID really is valid ID, naturally.
5309 * In router when NEW_ID packet is received (for new client) the
5310 hash of the Client ID is saved in the ID Cache but the
5311 client->nickname is set to NULL, instead of putting the hash
5314 IDENTIFY command now also checks that client->nickname must be
5315 valid. If it is not if will request the data from the server who
5316 owns the client. Added new function
5317 silc_server_command_identify_check.
5319 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5320 to set the command to already allocated Command Payload.
5322 * Tested private message sending in router environment with two
5323 routers, two servers and two clients. Fixed minor bugs and now
5326 * Fixed segfault from client's NAMES command. Used to crash if
5329 * Forwarded packets must not be routed even if it is not destined
5330 to the receiver. Changed server code comply with this.
5332 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5334 * Added `require_reverse_mapping' boolean value to ServerParams
5335 structure. If TRUE (not default) the server will require that
5336 the connecting host has fully qualified domain name.
5338 If the reverse mapping is not required and hostname could not be
5339 found the IP address is used as hostname.
5341 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Implemented version string checking to both client and server.
5344 The check is incomplete currently due to the abnormal version
5345 strings used in development version of SILC.
5347 * Changed all command functions in server to use the new
5350 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5352 * Changed char *data to unsigned char *data in ID Cache system to
5353 support binary data as ID Cache data. Changed code to support
5354 binary data in lib/silccore/idcache.c.
5356 * Renamed silc_server_packet_relay_command_reply to
5357 silc_server_command_reply as it is normal packet receiving
5358 function. Rewrote the function to accept command replys for
5359 servers and not only for clients.
5361 * Mark remote router always as registered server if we are connecting
5362 to it. Otherwise, commands sent by the router to us are ignored.
5364 * All ID List find routines now returns the ID Cache Entry pointer
5365 as well if requested.
5367 * WHOIS command works now in router environment, tested with two
5368 routers, two servers and two clients.
5370 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5371 in router environment (as it is almost equivalent to WHOIS) but
5372 hasn't been tested thoroughly. Added new functions:
5374 silc_server_command_identify_parse
5375 silc_server_command_identify_send_reply
5376 silc_server_command_identify_from_client
5377 silc_server_command_identify_from_server
5379 * Disabled route cache adding because adding two different ID's with
5380 same IP replaces the old cache entry thus giving wrong route.
5381 The entry->router->connection is always the fastest route anyway
5382 so route cache may not be needed. Of course, new routes maybe
5383 established after receiving the ID when the entry->router->connection
5384 might not be anymore the most optimal.
5386 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5388 * Add route cache for received ID for fast routing.
5390 * Added silc_server_packet_route to route received packet on router
5391 that is not destined to us.
5393 * Renamed silc_server_get_route to silc_server_route_get.
5395 * Added id_string and id_string_len fields into SilcServer to
5396 include encoded ServerID for fast comparing without excess
5397 encoding of the ID's.
5399 * Cleaned up WHOIS command on server side. Added following static
5402 silc_server_command_whois_parse
5403 silc_server_command_whois_check
5404 silc_server_command_whois_send_reply
5405 silc_server_command_whois_from_client
5406 silc_server_command_whois_from_server
5408 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5409 arguments in command replies. All command functions should be
5410 updated to use this macro.
5412 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Minor typo fixes on command reply handling on server.
5416 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Added silc_server_command_add_to_channel internal routine to add
5419 the client to the channel after router has created the channel and
5420 sent command reply to the server.
5422 * Added generic silc_server_send_command to send any command from
5425 * Use static buffer with ID rendering instead of duplicating data.
5427 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Fixed a channel user mode bug when joining to a channel server gave
5430 everybody channel founder rights, oops.
5432 * We mark ourselves as the router of the incoming server connection
5433 if we are router ourselves. This way we can check in some packet
5434 sending functions whether it is locally connected server. For
5435 incoming router connections we put NULL.
5437 * For router sending packets locally means now always sending the
5438 packet cell wide; to local clients and local servers. For normal
5439 server sending packet locally means sending it to only local
5442 * Fixed the JOIN command to really work in router environment. If the
5443 channel is created it is always created by the router. Router is
5444 also responsible of making the initial joining to the channel,
5445 sending JOIN notify to the sending server and distributing
5446 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5447 does not exist server doesn't do anything else but forward the
5448 command to the router which performs everything.
5450 * Added silc_server_send_channel_key function to send the Channel Key
5453 * Added silc_server_create_channel_key to create new channel key. The
5454 channel key is now re-generated everytime someone joins or leaves
5455 a channel, as protocol dictates. Note: channel->key_len is the
5458 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5461 packet_receive.[ch] to separate packet sending and receiving
5462 routines. The server.[ch] now includes everything else including
5463 actual packet processing (writing and reading data) and other
5466 Renamed silc_server_private_message_send_internal to
5467 silc_server_send_private_message. The routine is still though
5468 used only to relay private messages as server does not send
5469 private messages itself.
5471 Renamed silc_server_new_channel to silc_server_create_new_channel
5472 and added new function sicl_server_new_channel that handles the
5473 incoming New Channel packet. Added also new sending function
5474 silc_server_send_new_channel to send New Channel Payload.
5476 * Added new function silc_server_notify to process incoming notify
5477 packet to the server/router. Server may then relay the notify
5478 to clients if needed.
5480 * Added new function silc_server_new_channel_user to process incoming
5481 New Channel User packet. Router will redistribute the packet and
5482 send JOIN notify to its local clients and locally connected servers
5483 if needed. Normal server will send JOIN notify to its local client
5484 on same channel when received this packet. Added also corresponding
5485 sending function silc_server_send_new_channel_user to sent the
5488 * Added boolean route argument to send_notif_to_channel and
5489 packet_send_to_channel functions to attempt to route the packet
5490 if it is TRUE and send only locally if it is FALSE.
5492 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * silc_server_replace_id now broadcasts the received replace ID
5495 packet if it is not broadcast packet already. The router must
5496 broadcast to inform other routers about changed ID.
5498 * Added backpointer to server's router into SilcServer context in
5499 silcd/server_internal.h.
5501 * Fixed silc_server_packet_broadcast to send correct broadcast
5504 * The channel key is now distributed to the local client as soon
5505 as it is received from the router (in router environment) so that
5506 no other packet may be sent for the channel until client has
5509 * silc_server_remove_channel_user now broadcasts the received
5510 Remove Channel User packet if it is not broadcast packet already.
5511 The router must broadcast to inform other routers about removed
5514 * Added users field into SilcPacketContext that is a reference count
5515 of the context. One can increase the reference count by calling
5516 silc_packet_context_dup which is now changed to just increase the
5517 reference count instead of duplicating the data. The reference
5518 count is decresed by calling silc_packet_context_free that will
5519 free the data after the reference count hits zero.
5521 For now on the packet context and everything allocated into it
5522 (including the raw packet from network) must be freed by calling
5523 the new silc_packet_context_free function. Added also new function
5524 silc_packet_context_alloc that must be used now to allocate the
5525 context. This also means that if a routine is asynchronous from
5526 silc_[client/server]_packet_parse_type the packet context must
5527 be duplicated by calling silc_packet_context_dup. Otherwise it
5528 gets free'd after silc_[client/server]_packet_parse_type returns.
5529 Also, one must remember that if packet is duplicated then its
5530 reference count must be decresed by calling the free function as
5531 many times as it was duplicated.
5533 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5534 from both client and server.
5536 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Made joining to a channel working in router environment.
5540 * Cleaned up JOIN command on server side and create function
5541 silc_server_command_join_channel internal routine to make the
5544 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Changed silc_command_pending list to SilcDList. Also, added
5547 `ident' field to SilcServerCommandPending structure to identify
5548 the reply and to call correct callback.
5550 Added silc_server_command_pending_check function to replace the
5551 corresnponding macro. The silc_command_pending list is not
5554 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5555 to set identifier to previously allocated Command Payload. It
5556 is used to set identifier for command when resending Command
5559 * Added silc_command_payload_encode_payload to encode Command
5560 Payload buffer from SilcCommandPayload structure.
5562 * Added silc_argument_payload_encode_payload to encode Argument
5563 payload buffer from SilcArgumentPayload structure.
5565 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Changed WHOIS command to support router connection on server side.
5568 The whois request is always sent to router unless the server is
5569 standalone server. After server has received the reply from the
5570 router will it send the reply to the client.
5572 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5573 broadcast received broadcast packet. The function is used only
5574 by router. The broadcast packet is always sent to the router's
5577 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5578 render given ID to printable string, for log files for example.
5580 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Made basic router to router connections working. At least they
5583 can now connect to each other but nothing really works the way
5584 they are supposed - yet.
5586 * Added new initiator token to RouterConnection configuration
5587 file in silcd/serverconfig.[ch]. It is used to tell whether we
5588 are the initiator to the remote router or whether we'll expect
5589 the other end to connect.
5591 * Moved registering of listener task to silc_server_init, hence
5592 the server starts listenning as soon as it is run, even if it
5593 does not have connections to other routers. Let's see how well
5596 * Changed default connection retry timeouts for more suitable in
5599 * Removed cipher and such arguments from silc_idlist_add_client
5600 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5601 Added new function silc_idlist_add_data to add the keys and stuff
5604 * Added SilcIDListData structure and added it to SilcClientEntry
5605 and SilcServerEntry as their first field in the structure. This
5606 way we can explicitly cast the ID entries to the SilcIDListData
5607 structure and get common data for the entries. In past, we had
5608 to first check what type of connection it is and then cast it to
5609 correct ID entry type. Now, we can directly cast the opaque
5610 pointer to the SilcIDListData (no matter what ID entry it actually
5611 is) and get the data needed.
5613 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5616 in some circumstances even if threre were timeout tasks, though not
5617 IO tasks, but tasks anyway. Now fixed.
5619 * Defined SilcServerConnection structure to hold connection specific
5620 stuff about directly connected servers and routers. The definition
5621 is currently in silcd/server_internal.h. I thought about having
5622 a bit more important role fro this struct but for now it is used
5623 only when connecting to other server (or router actually).
5625 * Added connecting retry support in server when connecting to
5626 router(s). The retry feature implement exponential backoff
5627 algorithm. Also, added SilcServerParams structure to hold default
5628 parameters for server. For now, it include these retry settings
5629 and are hard coded. After server is moded to be as Silc Server
5630 Library this structure will be more important.
5632 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Changed client librarys channel->clients table to SilcList and
5635 changed code accordingly.
5637 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Changed client's channel table to SilcList and changed code
5640 accordingly. Also changed SilcChannelClientEntry to include back-
5641 pointer to the channel so that client entry can use that structure
5642 as list as well and we have fast cross-reference to the channel.
5643 This change dramatically decreased the complexity of channel
5644 handling with client entry and vice versa (removed one extra
5645 loop when searching for channel entry from many functions).
5647 * Changed server->sim from table to SilcDList and changed code
5650 * NAMES command can now be used from user interface. It will show
5651 the user list on the channel, neatly.
5653 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5654 Code now saves realname of the user if it becomes available.
5656 * Renamed configure.in to configure.in.pre and made ./prepare
5657 script to automatically add correct version string to
5658 configure.in which it creates from configure.in.pre.
5660 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * NAMES command reply now shows users mode with the nickname when
5665 * Moved silc_client_ch[u]mode[_char] functions from
5666 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5667 place sucks, they are utility functions and should be in some
5670 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5672 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5675 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5679 * Added TRQ (efficient deque and list library) into lib/trq. This is
5680 a very good list library that is currently used in the SILC. Defined
5681 SilcList API over the library because I didn't like the API very
5682 much. See lib/trq/silclist.h for the API and examples of how to
5683 use the API. Fixed various places in the code to use the new
5684 SilcList API. The SilcList is meant for lists that has a structure
5685 already defined as a list. It is not suitable to add just some
5686 context to the list (in TRQ, the context is the list actually).
5688 So, I defined SilcDList that can be used for the purpose where
5689 predefined list structure does not exit. This can be used as
5690 such list. Now some context just can be added to the SilcDList.
5691 Currently this list is not used in the SILC just yet, though there
5692 are a lot places where this can replace dynamically allocated
5693 tables and I will fix these places, later, to use SilcDList.
5694 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5695 and use TRQ internally).
5697 Also fixed some annoying warning messages that the original TRQ
5698 code generated. Also minor changes to TRQ's Makefile.in.
5700 * Added support for querying by Client ID to both WHOIS and
5701 IDENTIFY commands into server, as required by the protocol.
5703 * Removed method function pointers from SilcBuffer structure. They
5704 weren't used to anything and just increased the context size for
5705 no good reason. This change also made silc_buffer_alloc and
5706 silc_buffer_free functions inline functions.
5708 * Disabled command flooding detection support until it's fixed so
5709 that it accepts commands in but does not execute them more than once
5712 * Added silc_net_localhost(), to return local hostname, into
5713 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5714 that must be initialized before calling silc_client_init.
5716 * Added new function: silc_server_send_notify_on_channels to send
5717 notify messages to all channels client has joined. It is assured
5718 that the message is sent only once per client.
5720 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5721 lib/silcutil/silcutil.[ch] as silc_format function. The new
5722 function is generic and is used by server as well, not only by
5723 the logging routines.
5725 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5726 the provided version string was not acceptable. Added new function:
5727 silc_ske_check_version into lib/silcske/silcske.h. The function
5728 must be implemented by the application (client or server) and it
5729 does not reside in the SKE library. The function checks the version
5730 string remote end sent.
5732 * Added back pointers (to opaque context and to SilcSocketConnection)
5733 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5735 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5736 duplicate packet context structure.
5738 * Changed `notify' client operation to send same arguments as client
5739 receives from server except for ID's. ID's are mapped to correct
5740 ID entry and that is returned. Also, if channel entry is not sent
5741 by server but the notify is for channel the channel entry is sent
5742 to application (otherwise application doesn't know that it is for
5743 channel (library gets it from packet's Destination ID)).
5745 * Added silc_client_remove_from_channels into client library to
5746 remove a client from all channels it has joined to. Used when
5747 received SIGNOFF notify from server. Added also new function
5748 silc_client_replace_from_channels to replace old ID entry with
5749 new ID entry on all channels. Used when received NICK_CHANGE
5752 * Fixed ID Cache list handling in silc_idlist_get_client in
5753 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5754 to get (or query) client by ID.
5756 * Updated TODO list.
5758 * Added connection authentication status message defined by the
5759 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5760 support for these into the code in client and server side.
5762 * Added generic function silc_client_send_command to send any command
5763 with variable argument list. Application should use this function
5764 to send commands if the command functions provided by the library
5765 does not suite for the application's user interface needs.
5767 * Added new `failure' client operation. Application is notified about
5768 received failure packet if client is executing a protocol. In this
5769 case the protocol's execution has failed.
5771 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5772 is required by the protocol.
5774 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5775 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5778 * Added status flag to SilcSKE object to indicate realtime status
5779 of the SKE protocol.
5781 * Application receives now exactly same command reply arguments as
5782 the library receives from server. However, if ID is received the
5783 corresponding ID entry is returned to the application (eg. Client
5784 ID is mapped to correct SilcClientEntry entry and that is returned).
5785 Changed command_reply client operation due to this change.
5787 * Changed all ID's in commands and in command replys as ID Payloads.
5788 Change affected both client and server side codes.
5790 All ID's sent in SILC network (with execption of ID's in SILC
5791 Packet header) are sent in ID Payload to support variable length
5794 * Server now notifies nick changes and notifies all clients on
5795 the channels about the new nickname (about the new Client ID,
5798 * Implemented CMODE command to change channel modes. Supports all
5799 channel modes defined by the protocol specs except ban and invite
5800 lists. (Also, private channel key mode is supported but support for
5801 setting private channel key in client is missing, thus, this mode
5802 has no effect on client side (except that server requires that the
5803 client uses private channel key and normal channel traffic does not
5806 Also, invite mode works per se, but INVITE command does not work
5807 yet correctly, so you can set channel as invite only channel but
5808 inviting clients to the channel does not work (it is yet to be
5809 thought what's the best way to do it).
5811 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5812 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5813 Implemented CUMODE command to change user's mode on the channel.
5814 Supports all modes defined by the protocol specs.
5816 * Added NAMES command reply to return users modes on the channel.
5818 * Removed unnecessary and slow ciphers from lib/silccrypt.
5820 * Set SO_KEEPALIVE option to connection sockets by default.
5822 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5824 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5825 redefined the Notify Payload into protocol specs.
5827 * Added silc_id_payload_parse_id to get ID directly from raw
5830 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5833 accept searching by Client ID as well.
5835 * Added support for LEAVE and SIGNOFF notify types in client library.
5837 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5838 to parse ID Payload from raw data.
5840 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added flags parameter into silc_ske_assemble_security_properties
5843 function in lib/silcske/silcske.[ch].
5845 * Changed notify client operation to fit better for notify messages
5846 sent by server. The notify payload received from server is now
5847 passed to the application (after parsing it to SilcNotifyPayload).
5848 It is application's responsibility to retrieve the arguments
5849 from the payload and show the message the way it wants. The message
5850 sent by server is implementation specific.
5852 * Changed public keys to comply with the protocol specification.
5853 Old public keys are not supported anymore and are not compatible.
5855 * Removed nickname from Channel Payload as the latest draft removed
5856 it. The client must resolve the nickname from the NAMES command
5857 reply received when it joined the channel.
5859 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5861 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Fixed some errors in protocol specification drafts.
5865 * Created lib/silccore/silcnotify.c to implement Notify Payload
5866 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5867 generic payloads described by protocol specifications. The file
5868 includes implementations for ID Payload and Argument Payload.
5870 * Changed Command Payload implementation to use the new Argument
5871 Payload. Changed command_xxxx_payload to command_payload_xxxx
5872 to comply with SILC coding conventions.
5874 * Added suppport for Argument Payload handling in Notify Payload
5875 implementation as protocol requires it. Added the new support
5876 into server and client lib as well.
5878 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5880 * Added support for multiple nicknames on same channel. [n] is
5881 added locally to the nickname if there are more than one same
5882 nicknames on the channel.
5884 * Server now sends all nicknames that matched WHOIS request.
5885 Client also shows the list received from server.
5887 * Added TOPIC command to client side. User can now set and show
5888 current topic on channel.
5890 * Added MOTD command to client and server. Also, server sends the
5891 motd when client connects to the server.
5893 * Changed version strings to comply ISO 8601.
5895 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Fixed protocol error handling in client library. It should now
5898 cope even if the SKE fails for some reason.
5900 * Made new protocol specification drafts for submitting to IETF.
5902 * Implemented TOPIC command to server in silcd/command.c.
5904 * Added two new notify types into lib/silccore/silcnotify.h:
5905 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5906 notify nickname change and topic setting/change on a channel.
5908 * API change of command_reply operation in client library. The
5909 application gets now the status type received from server as well.
5911 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5915 * Cras fixed and optimized the packet handling even further and
5916 it should work now. Minor change to the prototype of function
5917 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5919 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added new function into lib/silcutil/silcschedule.[ch]:
5922 silc_schedule_with_fd to select() a specified fd. The function
5923 returns after timeout expires or data arrives or goes. The
5924 function is used by packet routines to wait that all data is
5925 received from network.
5927 * Fixed data reading from network in lib/silccore/silcpacket.c.
5928 The code now assures that all data is read from the fd and then
5929 continues packet processing. This was a bug fix since the code
5930 used to drop some data in some circumstances.
5932 * Added new function into lib/silcclient/client.[ch]:
5933 silc_client_start_key_exchange to start key exchange after
5934 connection has been established to server. The code internally
5935 now uses this funtion but its main purpose was to provide it
5936 for applications that perform their own connecting. After
5937 application has created a connection it merely calls this
5938 function to start the key exchange between client and server.
5939 The library takes care of everything else after that.
5941 Updated also lib/silcclient/README to explain the usage of
5944 * Do not send to application information that connection has
5945 been established. Application gets notified it by connect
5948 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Applied cras's patch to add silc_schedule_one function. The
5951 function runs scheduler once and returns.
5953 * Fixed the scheduler after cras messed it up. The timeout
5954 handling works now as it's supposed to work.
5956 * Added into lib/silccore/ silcnotify.h to include notify
5957 message types support. Changed silc_server_send_notify*
5958 functions, in server.[ch], to support those new notify types.
5959 Added the support for the notify types into client library,
5960 as well. Added new notify client operation into ops.h in
5963 * Changed silc_server_packet_send_to_channel to send normal
5964 packets instead of just channel message packets. The function
5965 is now used to send the notify packets to channels. It is not
5966 used to send channel message packets anymore, as server never
5969 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5970 va_arg()s as it seems to require it nowadays. I guess, if SILC
5971 is compiled with older va_arg() the new code should work anyway.
5973 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Splitted core library. Core library (lib/silccore) includes
5976 now only SILC protocol specific core (and common) components.
5977 Created new utility library (lib/silcutil) that includes more
5978 generic purpose stuff. The stuff for util library was taken
5979 from the old core library. This was minor and easy split.
5981 * Created SILC Client Library (lib/silcclient) that includes
5982 implementation of the SILC client without user interface. This
5983 was major move from silc/ directory. The code has been changed
5984 so that it is transparent towards the user interface. The
5985 silc/ directory includes now the same user interface as before
5986 and it uses the new client library. Read lib/silcclient/README.
5987 Basicly, the client library performs everything else related
5988 to SILC except user interface handling. Also, configuration
5989 files are considered to be part of user interface and library
5990 does not handle them.
5992 This change also changed a lot of structures, function naming etc.
5993 Most important change was that SilcClientWindow object was
5994 renamed to SilcClientConnection in the client library. Created
5995 also new file lib/silcclient/ops.h. Also added new files
5996 silc/local_command.[ch] and silc/client_ops.[ch].
5998 All these changes were made to make it easier for user interface
5999 designers to create what ever user interface for the SILC client
6002 It is also expected that the server will be moved to lib
6003 directory as well and SILC Server Library will be created;
6004 sometimes in the future.
6006 * Removed Local commands from lib/silccore/silccommand.h as
6007 they are application specific and new client library does not
6008 handle any of those anymore.
6010 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6011 old client implementation in silc/.
6013 * Added support for callback functions in SILC_LOG_* macros.
6014 Application can now set its own callbacks that will be called
6015 instead of using the default functions that will always print
6016 the debug messages to stderr (or stdout). Also, debugging can
6017 now be disabled by setting silc_debug to FALSE and re-enabled by
6018 setting it to TRUE. Note, that logging will still work even
6019 if debugging is disabled.
6021 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6022 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6023 silc_log_reset_debug_callbacks.
6025 * To enable debugging in silc client one must give now -d
6026 option on command line.
6028 * Changed silc_schedule_init to automatically allocate task queues
6029 if they are not allocated before calling it.
6031 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6033 * Added GMP 3.1 into math library.
6035 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6037 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6038 a channel in SILC network. The packet is used by servers and
6039 routers to notify other routers that user has left a channel.
6040 This little feature was missing until now. Added the feature
6041 to protocol specification as well.
6043 Added functions: silc_server_send_remove_channel_user and
6044 silc_server_remove_channel_user into server.[ch].
6046 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6047 lib/silccore/silcpacket.h. However, they are not implemented
6050 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6052 * Fixed joining to a channel and sending channel messages
6053 between server and router. The channel message sending should
6054 now work inside a cell.
6056 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Fixed the private message sending between server and router.
6059 The private message sending should now work inside a cell.
6061 * Added silc_server_replace_id into server.[ch] to replace
6062 existing ID in the SILC network.
6064 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6065 and silc_idlist_replace_server_id into idlist.[ch] in server.
6067 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Fixed the server to server connections. Server can again now
6070 connect to router. Router to router connections probably does
6073 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Added dynamic protocol registering support. Now protocols can
6076 registered and unregistered on the fly. Patch by cras.
6078 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added lib/contrib directory to hold routines that some platforms
6081 don't have but are needed by SILC.
6083 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6084 into lin/contrib to provide getopt() and getopt_long() for
6085 those who don't have it.
6087 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Added AWAY command to client. When away message is set and
6090 client receives a private message packet the client automatically
6091 replies to the sender with the away message.
6093 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6094 bug seemed to be the cause of recent problems when compiling
6097 * Added version detection support to SKE protocol specification
6098 and added the new changes to the SKE implementation as well.
6099 There were other minor changes in the SKE protocol as well.
6101 Many changes in lib/silcske/silcske.[ch] and in
6102 lib/silcske/payload.[ch].
6104 * Added ^U functionality, clear input line. Patch from cras.
6106 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6108 * Mainly small bugfixes on core library. Fixed some debugging
6109 logging and buffer overflow in silclog.c.
6111 * Updated config.sub and config.guess on the distribution tree.
6113 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Added command lagging support in server. Client may execute
6116 commands now only once in two seconds.
6118 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Optimized packet reception. MAC computation and checking is now
6121 also more optimized. A lot previously duplicated code is now
6122 used as generic by both client and server.
6124 * Fixed key pair generation in clientutil.c
6126 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Added into lib/silccore/silcbufutil.[ch] new function;
6129 silc_buffer_realloc.
6131 * Moved generic packet sending/encryption functions to
6132 lib/silccore/silcpacket.[ch] from client and server. Some
6133 rewriting of the functions.
6135 * Moved all generic packet reception/decryption functions to
6136 lib/silccore/silcpacket.[ch] from client and server. The
6137 packet processing is now much cleaner in both client and server.
6138 These were major changes in both client and server.
6140 * Created many common functions in server to do packet sending.
6141 Previously code were duplicated a lot, this has been removed
6144 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6146 * Rewrote major parts of the ID cache system. Don't know
6147 whether it is better now or not but at least the API is more
6150 * Major rewrite on ID cache stuff on client because of the ID
6151 cache API changes. Added idlist.c to client.
6153 * Also major rewrite on ID cache stuff on server as well.
6154 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6155 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6156 in hand, instead they are all put into the ID cache system now.
6157 All server_idlist_* routines uses ID cache now instead of
6158 traversing its own lists (those lists does not exist anymore).
6159 SilcIDList though still exists. Also, SilcXXXEntry's are
6162 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Finally made the SKE implementation compliant to the protocol
6165 specification. All mp integers are now binary encoded as
6166 opposed being HEX encoded.
6168 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6171 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6172 functions: silc_[encode/decode]_pem. Also added function
6173 silc_encode_pem_file to PEM encode with newlines ('\n') for
6176 * SILC public keys are now encoded either PEM or binary. Same
6177 option is for private keys as well. By default private keys
6178 are binary encoded and public keys PEM encoded. Silly HEX
6179 encoding were removed.
6181 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6182 function to create fingerprints.
6184 * Fixed a bug in SHA1; does not change the original data anymore.
6186 * Partly implemented INFO command on client and server side.
6187 Fixed CLEAR command. Changes to SERVER command; show current
6188 server(s) when giving command without arguments. Added
6189 VERSION command to client.
6191 * Added check to server that unregistered connections cannot
6192 execute commands (unless it is specificly allowed).
6194 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Fixed screen refresh.
6198 * Fixed channel joining bug from client. On some circumstances
6199 client tried to join to a channel it had already joined.
6201 * Added public key verification process into client's protocol.c.
6202 The client now verifies the public key from user and saves
6203 it into ~./silc/serverkeys/ directory.
6205 Added into: clientutil.[ch]: silc_client_verify_server_key.
6207 * Changed SKE protocol's silc_ske_initiator_finish function
6208 to accept callback function that verifies the received public
6209 key. Removed old silc_ske_verify_public_key function.
6211 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6214 silc_pkcs_private_key[_data]_set.
6216 * Made the password and public authentication more cleaner in
6217 server's protocol.c.
6219 * Removed historic and obsolete protocol `channel_auth' from
6220 both client and server.
6222 * Removed wrong way of sending command status messages from
6223 server to client in server's command.c. The old way violated
6224 protocol specification.
6226 Changes to silccore/silccommand.[ch]: removed
6227 silc_command_encode_status_payload -> not needed anymore,
6228 changed silc_command_encode_payload_va to accept extra
6229 argument on variable argument list. The argument type must
6230 now be provided to the function. Also, added new function:
6231 silc_command_encode_reply_payload_va which is same as
6232 normal command_encode_payload_va except command status type
6233 is provided as extra argument.
6235 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Added ~./silc directory handling. The directory includes the
6238 public and private keys for the client.
6240 Added silc_client_check_silc_dir, silc_client_create_identifier
6241 and silc_client_load_keys.
6243 * Implemented SILC protocol compliant public key. Added public
6244 and private key saving to and loading from files.
6246 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6247 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6248 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6249 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6250 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6252 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6253 silc_pkcs_load_[public/private]_key.
6255 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6257 * Added silc_server_get_route (route.[ch]) to get connection
6258 data for the fastest route for given ID.
6260 * Implemented INVITE command on client and server. The command
6261 were re-defined in the SILC Protocol Specification and the
6262 implementation now complies with the specification.
6264 * Implemented PING command on client and server.
6266 * Implemented NAMES command on client and server. The server side
6267 supports currently only normal server not router server yet.
6268 Some changes to NAMES definition in SILC protocol specification.
6270 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Implemented LEAVE command on client and server.
6274 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6275 again. This change was made to the protocol as well. Server
6276 should not violate the protocol specification anymore.
6278 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6281 was tested. SOCKS4 was not but should work anyway.
