36 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
38 * Fixed LIST command reply sending in server. Affected file
41 * Server now sends the kicker's client ID in the KICK notify
42 to the kicked client. Affected file silcd/command.c.
44 * The client library now parses the kickers client ID and
45 UI displays it. Affected files lib/silcclient/client_notify.c
46 and irssi/src/silc/core/silc-channels.c, module-formats.c.
48 * Made all payload parsing function prototypes consistent.
49 They all take now const unsigned char * and uint32 pair as
50 the payload data instead of SilcBuffer. Changes all around
51 the source tree. Other unsigned char* -> const unsigned char*
52 changes around the tree as well.
54 * Optimized SFTP client and server packet sending not to
55 allocate new buffer for each packet but to recycle the
56 first allocated buffer. Affected files are
57 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
59 * Optimized the SFTP client to use SilcList instead of
60 SilcDList for requests, because it is faster. Affected file
61 is lib/silcsftp/sftp_client.c.
63 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
64 into lib/silccore/silcid.[ch].
66 Renamed silcpayload.[ch] into silcargument.[ch].
68 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
70 * If client entry is deleted with active key agreement
71 session, abort the session.
73 The silc_client_abort_key_agreement now calls the completion
74 callback with new SILC_KEY_AGREEMENT_ABORTED status.
76 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
79 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
81 * Don't use __restrict in older GCC's. Affected file is
82 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
84 * silc_net_localhost now attempts to reverse lookup the
85 IP/hostname. Affected file lib/silcutil/silcnet.c.
87 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
88 command. It can be used to gain founder privileges at
89 the same time when joining the channel.
91 Defined that the SILC_NOTIFY_TYPE_KICKED send the
92 kicker's client ID as well. Updated protocol specs.
94 Defined that the server must send SILC_COMMAND_IDENTIFY
95 command reply with error status to client who sent
96 private message with invalid client ID.
98 Updated the protocol specification.
100 * Added silc_server_send_command_reply to send any
101 command reply. Affected file silcd/packet_send.[ch].
103 * Added silc_id_payload_encode_data to encode ID payload
104 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
106 * The server now send IDENTIFY command reply with error
107 status if client ID in private message is invalid. Affected
108 file silcd/packet_receive.c.
110 * Save the server key file with server's IP address in
111 the filename instead of hostname. The affected file is
112 irssi/src/silc/core/client_ops.c.
114 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
116 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
119 * Added libtool support for compiling shared objects in
120 lib/silcsim. Affected file configure.in.pre and
121 lib/silcsim/Makefile.am. Original patch by cras.
123 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
125 * Pid file configuration, and server's config file fixes
126 patch by toma. Updated CREDITS file.
128 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Fixed silc_client_channel_message to not try to decrypt
131 the message twice if it resolved the destination client
132 information. This could cause of dropping one channel
133 message. Affected file lib/silcclient/client_channel.c.
135 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Added silc_client_run_one into lib/silcclient/silcapi.h and
138 lib/silcclient/client.c. This function is used when the SILC
139 Client is run under some other scheduler, or event loop or
140 main loop. On GUI applications, for example this may be
141 desired to used to run the client under the GUI application's
142 main loop. Typically the GUI application would register an
143 idle task that calls this function multiple times in a second
144 to quickly process the SILC specific data.
146 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
148 * Fixed silc_server_drop() for dropping the supplementary
149 groups as well, this could cause a security hole on some
152 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
154 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

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

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

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

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

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

825 protocol specification.
827 * Removed one redundant channel key generation from normal
828 server during joining procedure. Removed one redundant
829 channel key sending from server to router during joining
830 procedure. Affected file silcd/command.c.
832 * Made minor bugfixes to the backup router resuming protocol.
833 Affected file silcd/server_backup.c, server.c.
835 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

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

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

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

970 entry always, not just when the command is coming from client.
971 Affected file silcd/command.c.
973 * Added new function silc_server_packet_queue_purge to purge the
974 outgoing data queue to the network. After the function returns
975 it is guaranteed that the outgoing packet queue is empty.
976 Affected file silcd/packet_send.[ch].
978 * Purge the outgoing packet queue in the rekey protocol's final
979 callback to assure that all rekey packets go to the network
980 before quitting the protocol. Affected file silcd/server.c.
982 * Added silc_client_packet_queue_parse as similar function as
983 in server to the client library. The affected file is
984 lib/silcclient/client.c.
986 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Splitted silcd/server.c and created silcd/server_util.[ch]
989 for utility functions.
991 * Added new socket flag SILC_SF_DISABLED to indicate that the
992 connection is open but nothing can be sent to or received from
993 the connection. Affected file lib/silcutil/silsockconn.[ch].
994 The checking for disabled socket is checked in the low level
995 silc_socket_write and silc_socket_read functions.
997 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Allow only nicknames and channel names that fits into the
1000 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1002 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1004 * When processing JOIN command reply in server check that if
1005 the channel exists in our global list we'll move it the local
1006 list. Affected file silcd/command_reply.c.
1008 * Fixed the check whether client is joined on the channel already
1009 in JOIN command. Affected file lib/silcclient/command.c.
1011 * Fixed the JOIN command reply to check whether the channel
1012 already exists. Affected file lib/silcclient/command_reply.c.
1014 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1016 * Added silc_ske_status_string to map the SKE error numbers
1017 to readable strings. The affected files are
1018 lib/silcske/silcske[_status].[ch].
1020 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Do not show the private channels on the WHOIS channel list
1023 as it is not allowed by the protocol. The affected file is
1026 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Assure that the packet length digged from the actual packet
1029 is something sensible in the silc_packet_decrypt_rest_special
1030 in lib/silccrypt/silcpacket.c.
1032 * Free and NULL the allocated pointer in silc_hmac_alloc if
1033 the HMAC allocation fails. The affected file is
1034 lib/silccrypt/silchmac.c.
1036 * Print the selected security properties to the log files in
1037 the server. Affected file silcd/protocol.c.
1039 * Add SKE's reference counter even if calling the completion
1040 callback manually. Otherwise it goes negative, although it
1041 does not cause any problems. The affected file is
1042 lib/silcske/silcske.c.
1044 * Remove the client entry with short timeout after giving the
1045 KILL command. Affected file lib/silcclient/command.c.
1047 * Fixed to send error reply in WHOIS and IDENTIFY commands in
1048 case all found clients are already disconnected (WHOWAS would
1049 found them) in the server. Affected file silcd/command.c.
1051 * Update the last_receive (time of last data received) to be
1052 updated only when received private or channel message so that
1053 the idle time showed in WHOIS makes more sense.
1055 * Added boolean field `valid' in to the SilcClientEntry in the
1056 client library to indicate whether the entry is valid or not.
1057 This fixes the nickname change bug on channel when changing
1058 the nickname to be same than the old (like nick to Nick) the
1059 nickname formatter doesn't set the new nick anymore to Nick@host.
1060 Affected file lib/silcclient/idlist.[ch].
1062 * Now actually fixed the nickname changing on disconnection.
1063 Added new function silc_change_nick to the Irssi SILC Client.
1064 Affected file irssi/src/silc/core/client_ops.c,
1065 irssi/src/silc/core/silc-nicklist.[ch].
1067 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1069 * Check that the public key exists in the GETKEY command before
1070 trying to encode it. Affected file silcd/command.c.
1072 * Print some notifications on received public keys with GETKEY
1073 command in the Irssi SILC Client. Affected files are
1074 irssi/src/fe-common/silc/module-formats.[ch],
1075 irssi/src/silc/core/client_ops.c.
1077 * Use IDENTIFY command to resolve the server information in the
1078 GETKEY command instead of INFO command. Affected file
1079 lib/silcclient/command.c.
1081 * All command reply functions in the client library now calls
1082 the pending command reply callbacks even if an error has
1083 occurred. The server has done this a long time and now it was
1084 time to move the client library to this as well. Now all
1085 errors can be delivered back to the pending command reply
1086 callbacks if necessary. Affected files are
1087 lib/silcclient/command[_reply].[ch].
1089 * Change the nickname on disconnection back to the username
1090 because in reconnect the server will enforce it to it anyway.
1091 Affected file irssi/src/silc/core/silc-servers.c.
1093 * Fixed a config file parsing bug in the Irssi SILC client.
1094 Affected file irssi/src/silc/core/clientconfig.c.
1096 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * When printing the channel mode on JOIN, verify that the
1099 channel key and channel's HMAC are valid. Affected file
1100 irssi/src/silc/core/client_ops.c.
1102 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
1105 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
1106 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
1108 * Removed channel key rekey task deleting from the function
1109 silc_server_save_channel_key. Affected file silcd/server.c.
1110 Added explicit timeout task context instead that is used to
1111 delete the task if we are registering a new task before the
1112 new task has elapsed.
1114 * When channel key rekey occurs the client library now saves
1115 the old channel key for a short period of time (10 seconds) and
1116 is able to use it in case some is still sending channel
1117 messages encrypted with the old key after the rekey. Affected
1118 file lib/silcclient/[idlist.h|client_channel.c].
1120 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Added check to the silc_server_new_id_real to not accept
1123 new ID if it is the sender's own ID. Affected file is
1124 silcd/packet_receive.c.
1126 * Assure that we do not announce ourself or the one we've
1127 sending our announcements when we're router and are announcing
1128 servers to our primary router. Affected file silcd/server.c.
1130 * Fixed silc_server_command_identify_check_client to assemble
1131 correct WHOIS packet. It send corrupted WHOIS packet and
1132 caused problem with router to router connections. Affected
1133 file silcd/command.c.
1135 Fixed also silc_server_command_whois_check the same way
1136 as for the IDENTIFY command.
1138 * Added new SilcIDListStatus to the server in the SilcIDListData
1139 structure. The status now includes the current status of
1140 the entry (like registered, resolved etc.). Affected file
1141 silcd/idlist.[ch]. Defined a bunch of different status types
1142 as well. This replaced the old boolean registered field as well.
1144 Added resolve_cmd_ident field to the SilcClientEntry structure
1145 too so that if the entry is for example being resolved so
1146 another command may attach to the same pending command reply
1147 without requiring to resolve the same entry again. This concept
1148 should optimize the WHOIS and the IDENTIFY resolving under
1149 heavy load by taking away unnecessary resolving for entries
1150 that are being resolved already.
1152 Added support for adding multiple pending commands for one
1153 command idenfier. Affected file silcd/command[_reply].[ch].
1155 * Fixed WHOIS and IDENTIFY save to remove the cache entry
1156 before deleting the data. Otherwise the hash table will have
1157 freed data in comparison functions. Affected file is
1158 silcd/command_reply.c.
1160 * Fixed silc_idlist_replace_client_id to add the new entry to
1161 the cache with NULL nickname. Otherwise there will be invalid
1162 memory as the nickname after the nickname is freed. Affected
1163 file silcd/packet_receive.c.
1165 * Fixed the silc_idlist_get_clients_by_hash. The entries was
1166 saved into wrong slots because the previous number of entries
1167 was not taken into account. Affected file silcd/idlist.c.
1168 Fixed same thing in silc_idlist_get_clients_by_nickname too.
1170 * If we are router and we receive JOIN notify to a channel that
1171 does not have any users then notified client is marked as the
1172 channel founder, as it is it. The affected file is
1173 silcd/packet_receive.c
1175 * Added to the extended hash table API's table_del_*ext functions
1176 the destructor as argument too, so that the caller can decide
1177 which destructor to use or whether to use destructor at all.
1178 Affected file lib/silcutil/silchashtable.[ch].
1180 * Fixed ID Cache purging. It actually deleted the entries from
1181 the hash table after the data was freed. The hash table ended
1182 up comparing freed memory. The affected file is
1183 lib/silccore/silcidcache.c.
1185 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1187 * Fixed Irssi SILC client's KILL command's HELP syntax.
1189 * The USERS command now resolves the detailed user information
1190 if the userinfo field is missing. Affected file is
1191 lib/silcclient/command_reply.c.
1193 * Do not print error in silc_file_read if the read file does
1194 not exist. Just silently return NULL. Affected file is
1195 lib/silcutil/silcutil.c.
1197 * Fixed the silc_log_output to not wine about NULL filename
1198 and to not create some bogus " " filename. Affected file is
1199 lib/silcutil/silclog.c.
1201 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Fixed various printing bugs on the user interface in the
1204 Irssi SILC Client. Minor changes that were forgotten from
1207 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Fixed the configure.in.pre and the compilation and distribution
1210 environment to support the new autoconf 2.52. That version is
1211 now required to compile the CVS trunk.
1213 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1215 * Renamed function silc_parse_nickname to silc_parse_userfqdn
1216 to generally parse user@fqdn format strings. Affected file
1217 lib/silcutil/silcutil.c.
1219 * Added nickname_format and nickname_force_format fields to the
1220 SilcClientParams structure. The first one defines the format
1221 for the nicknames that the library will enforce if the receives
1222 multiple same nicknames. The second one is boolean value and
1223 can be used to force the library to always enforce the format
1224 to the nicknames regardles whether there are multiple nicknames
1225 or not. This configurable formatting was employed to flexibly
1226 support accessing multiple nicknames from the user interface.
1227 The userinterface can now set the nicknames to what ever format
1228 they prefer. Affected file lib/silcclient/silcapi.h.
1230 Added function silc_client_nickname_format to the file
1231 lib/silcclient/idlist.c. It performs the nickname formatting.
1233 Added new field `hostname´ to the SilcClientEntry context.
1234 It holds the hostname of the client. Affected file is
1235 lib/silcclient/idlist.h.
1237 * Irssi SILC Client sets the nicknames in nick@hostn format.
1238 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
1239 irssi/src/silc/core/silc-core.c.
1241 The WHOIS printing now also shows both the real nickname and
1242 the formatted nickname so that user knows how to access the
1243 user if there are multiple same nicknames cached. Affected
1244 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
1245 printing formatting too to take the hostname now as a separate
1246 argument. The Affected file is
1247 irssi/src/fe-common/silc/modules-formats.[ch].
1249 * Changed the silc_client_get_clients_local to accept the formatted
1250 nickname as argument. It accepts the real nickname too but the
1251 formatted nickname can be used to find the true entry from
1252 multiple entries. Affected file lib/silcclient/silcapi.h and
1253 lib/silcclient/idlist.c.
1255 * Added nickname_format_parse field to the SilcClientParams.
1256 It is a callback function provided by the application to parse
1257 the nickname out of the formatted nickname string. The library
1258 calls it to get the nickname from the formatted string. Since
1259 the application generally knows better the format of the nickname
1260 string it parses it instead of the library, even though library
1261 encodes the formatted string. If the callback function is not
1262 provided then the library will use the string as is. The
1263 affected file is lib/silcclient/silcapi.h.
1265 * All the nickname strings passed to the client library in
1266 commands are now expected to be formatted nickname strings.
1267 If the command does not support the formatted nickname string
1268 it will assume that the sent string is the actual nickname.
1269 Affected file lib/silcclient/command.c.
1271 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Added public key authentication support to OPER and SILCOPER
1274 commands in the client library. Affected file is
1275 lib/silcclient/command.c.
1277 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1279 * Changed the get_auth_methdod client operation to be asynchronous.
1280 It can be async if the application resolves the authentication
1281 method from the server during the negotiation. Added new
1282 SilcGetAuthMeth completion callback that the application will
1283 call after resolving the authentication method.
1285 Added function silc_client_request_authentication_method that
1286 the application can use to resolve the authentication method
1287 from the server. Added also SilcConnectionAuthRequest callback
1288 that the library will call after the server has replied. The
1289 application can call this function if it does not know the
1290 current authentication method.
1292 Affected files are lib/silcclient/client.c and
1293 lib/silcclient/silcapi.h.
1295 * The Irssi SILC client now automatically resolves the authentication
1296 method incase any configuration information is not present (and
1297 currently there never is). The affected file is
1298 irssi/src/silc/core/client_ops.c.
1300 * Fixed public key authentication from the client library.
1301 Affected file lib/silcclient/protocol.c. Changed also the
1302 protocol specification about the public key authentication in
1303 the connection authentication protocol. The actual data to be
1304 signed is now computed with a hash function before signing.
1306 * Fixed the public key authentication from the server as well.
1307 Affected file silcd/protocol.c.
1309 * Removed the mlock()'s from the memory allocation routines.
1310 Affected file lib/silcutil/silcmemory.c. The ./configure does
1311 not check anymore for the mlock(). Affected file is
1314 * Fixed USERS command in server to allow the execution of the
1315 command for private and secret channels if the client sending
1316 the command is on the channel. Affected file silcd/command.c.
1318 * Fixed silc_client_get_clients_local to return the clients
1319 count correctly. It could return wrong value. Affected file
1320 lib/silcclient/idlist.c.
1322 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1324 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1325 types. The assembler optimizations seemed not to like 64-bit
1326 data types. The assmebler optimizations thus are now enabled
1327 also for BSD systems as opposed to only enable them for Linux.
1329 * Do not check for threads at all on BSD systems. Affected
1330 file configure.in.pre.
1332 * Removed -n and -h options from the Irssi SILC Client since
1333 they are not used in silc.
1335 * Fixed the prime generation to assure that the first digit
1336 of the generated random number is not zero since our conversion
1337 routines does not like number strings that starts with zero
1338 digit. If zero digit is seen the random number is regenerated.
1339 This caused some corrupted RSA keys when the zero first digit
1340 was met. Affected file lib/silcmath/silcprimegen.c.
1342 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Fixed WIN32 configuration in the ./configure script.
1345 Fixed to include xti.h on environments that has it.
1346 Patches by Carsten Ilchmann and andrew.
1348 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Changed the silc_id_create_client_id to be collision
1351 resistant. It is now assured that there cannot be created
1352 two same client ID's. I suspect that some weird bugs in
1353 the server were actually caused by duplicate Client IDs.
1354 Affected file silcd/serverid.[ch]. A router receiving
1355 new ID now also assures and informs the sending server
1356 if the ID caused collision.
1358 * Changed the silc_id_create_channel_id to also assure that
1359 there are no collisions.
1361 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * Statement about ignoring the Mutual Authentication flag when
1364 performing rekey with PFS was a bit misleading. It is ignored
1365 if it was set in the initial negotiation, it cannot be even
1366 set in the rekey. Fixed in the ke-auth draft. Started the
1367 new versions of the protocol drafts in the doc/.
1369 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Fixed a bug in silc_client_command_identify_save when saving
1372 new channel information. The channel name was no duplicated
1373 and caused crash on exit. Affected file is
1374 lib/silcclient/command_reply.c.
1376 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Fixed the getkey command handling in the server. Send just
1379 empty OK reply to the sender if the key could not be fetched
1380 (but everything else was ok, like the key just was not available).
1381 Changed the public key parameter to optional in the protocol
1382 specs so that empty OK reply can be sent. Affected file
1385 Added a message to Irssi SILC client to tell to user if the
1386 server did not return a public key.
1388 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1390 * Fixed a channel key regeneration bug. It registered new
1391 timeout tasks exponentially until all system resources were
1392 used. Affected file silcd/server.c.
1394 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Added the SILC Document generator to the scripts/silcdoc.
1397 It can be used to generate the Toolkit Reference Manual out
1398 of the source tree. Internally it will also use the RoboDoc
1399 generator now imported in util/robodoc.
1401 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1403 * Added couple of return's in rekey protocol if error orccurred
1404 during the protocol. The execution must be terminated.
1405 Affected file silcd/protocol.c. Also, terminate the protocol
1406 always with timeout.
1408 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * The client's Client ID was created initally from the wrong
1411 nickname (it could have been in format nick@host) in the
1412 silc_server_new_client. Affected file silcd/packet_receive.c
1414 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Added some SILC_LOG_ERROR's to various error conditions
1417 if client could not be added to ID cache. Affected files
1418 silcd/packet_receive.c and silcd/server.c.
1420 * When client's sock->user_data is freed, NULL also the
1421 client->router and client->connection pointers. Added check
1422 for these pointers being NULL to various places around the
1423 code. Affected file silcd/server.c.
1425 * Added client->data.registered == TRUE checks to various
1426 places around the code to assure that unregistered client's
1427 are not handled when it is not allowed. Affected file
1430 * Added `bool registered' fields to all
1431 silc_idlist_[server|client]_get_* routines to indicate whether
1432 the fetched client needs to be registered or not. Affected
1433 file silcd/idlist.[ch].
1435 * Add your own entry as registered to the ID cache in the
1436 server. Affected file server.c.
1438 * Fixed a bug in silc_server_new_server. The SilcServer was
1439 set as the new server's context instead of SilcServerEntry.
1440 This naturally caused some weird bugs.
1442 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Do not delete the channel rekey task when adding it
1445 for in silc_server_create_channel_key.
1447 * Changed the silc_server_create_channel_key to return
1448 TRUE or FALSE to indicate the success of the channel key
1451 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Fixed MSVC++ project files and added missing files to
1454 Makefiles under win32/.
1456 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Do not add TCP_NODELAY flag if the operating system
1459 does not have it defined. Affected files are
1460 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1462 * Fixed buffer overflow from Irssi SILC Client. Affected
1463 file irssi/src/fe-common/core/themes.c.
1465 * Fixed double free in client library in the file
1466 lib/silcclient/client.c when disconnecting from server.
1468 * Applied double free patch from cras to Irssi SILC client.
1469 Affected files irssi/src/core/[modules/expandos].c
1471 * Fixed the disconnection handling to Irssi SILC Client.
1472 The application must call silc_client_close_connection
1473 in ops->connect client operation in case of failure of
1474 the connection. Affected file is
1475 irssi/src/silc/core/client_ops.c.
1477 * Do not set sock->protocol to NULL in the function
1478 silc_client_close_connection after executing the protocol's
1479 final callback since the sock might not be valid anymore.
1480 Affected file lib/silcclient/client.c.
1482 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1484 * Do not enable SILC_THREADS if the linking with libpthread
1485 did not happen. Affected file configure.in.pre.
1487 * Added notion to protocol specification that server must
1488 verify the sent authentication payload with CMODE when
1489 setting the channel founder key. Implemented it to the
1490 server. Affected file silcd/command.c.
1492 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1494 * Added _EXTRA_DIST SILC distribution variable to the
1495 distributions file. It is used to conditionally add extra
1496 files or directories to the specific distribution. Affected
1497 files ./prepare, Makefile.am.pre and distributions.
1499 Removed the `_' from the start of the distribution names.
1502 * Added README.WIN32 for instructions to compile the Toolkit
1505 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Fixed a double free in disconnection in the server. Affected
1508 file is silcd/server.c.
1510 * Fixed the lib/silcske/groups.c to work now also with GMP
1511 MP library. The string conversion did not work when using
1512 specific base and the base is indicated in the string as well.
1514 * Created win32/ directory which now includes MSVC++ specific
1515 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1516 It will appear only in the toolkit distribution
1518 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Changed the key material distribution function in case when
1521 the hash output is too short. The data is now concatenated
1522 a bit differently than it used to. Made the change to the
1523 SKE protocol specification.
1525 * Added better GMP detection to configure.in.pre. A patch
1528 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Fixed a minor bug in SKE that might cause some problem on
1531 some platforms. Affected file lib/silcske/silcske.c.
1533 * Added the cookie checking for initiator in the SKE. It checks
1534 that the responder returns the sent cookie unmodified. The
1535 affected file is lib/silcske/silcske.c. Added new SKE
1536 error type INVALID_COOKIE that can be sent during the
1537 negotiation. Fixed some memory leaks as well.
1539 * Added the "invalid cookie" error message to Irssi SILC client's
1542 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Added `task_max' field to the SilcClientParams to indicate
1545 the maximum tasks the scheduler can handle. If set to zero,
1546 default values are used. Affected file lib/silcclient/silcapi.h.
1548 * Fixed memory leaks in silc_client_close_connection. Affected
1549 file lib/silcclient/client.c.
1551 * Added silc_client_del_client_entry to client library to free
1552 all memory of given client entry. Affected file is
1553 lib/silcclient/idlist.[ch].
1555 * Added new functions silc_client_del_channel and
1556 silc_client_del_server to delete channel and server entries.
1557 Affected file lib/silcclient/[silcapi.h/idlist.c].
1559 * Removed silc_client_del_client_by_id from silcapi.h.
1561 * Fixed the INFO command to return the server's own info
1562 correctly when querying by Server ID. Affected file is
1565 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Removed the non-blocking settings in WIN32 code in the
1568 silc_sock_[read/write] and added SleepEx instead. Affected
1569 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1570 of input data is now checked with FIONREAD and ioctlsocket.
1572 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Call silc_schedule_task_del_by_context in the
1575 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1576 Affected file lib/silccore/silcprotocol.c.
1578 * Call silc_protocol_cancel for active protocols in the
1579 silc_server_close_connection if the funtion
1580 silc_server_free_sock_user_data has not been called.
1581 Affected file silcd/server.c.
1583 * Generic tasks cannot be deleted using the del_by_fd
1584 task deleting function since generic tasks does not match
1585 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1587 * Added a notion to SILCOPER help file that the SILCOPER works
1588 only on router server, not on normal server.
1590 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Added for WIN32 support for the new scheduler as well.
1593 Affected file lib/silcutil/win32/silcwin32schedule.c.
1595 * Fixed the SHA1 implementation to work on various platforms.
1597 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1600 API. It is part of the scheduler now. Everything else is
1601 as previously but some functions has changed their names.
1602 Checkout the lib/silcutil/silcschedule.h for the interface.
1603 Updated all applications to use the new interface. Affected
1604 files are lib/silcutil/silcschedule.[ch].
1606 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1608 * Found a bug in the SKE implementation. The HASH value,
1609 specified by the protocol, was not computed correctly. The
1610 public key of the responder was not added to the computation
1611 even though it is mandatory. Affected file lib/silcske/silcske.c.
1612 This unfortunately causes incompatibilities with older
1613 clients and servers.
1615 * Added WIN32 specific network init and uninit functions:
1616 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1617 the Winsock2. Affected file lib/silcutil/silcnet.h and
1618 lib/silcutil/win32/silcwin32net.c.
1620 * Set the socket always to nonblocking mode on WIN32 after
1621 reading data or writing data. Affected file is
1622 lib/silcutil/win32/silcwin32sockconn.c.
1624 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Fixed various compilation problems under WIN32. Affected
1627 files lib/silcutil/win32/silcwin32thread.c and
1628 lib/silcutil/win32/silcwin32schedule.c.
1630 * Removed all _internal.h #includes from public header
1631 files. Internal headers must never be included from
1634 Removed also the lib/silcske/payload_internal.h file.
1636 * All include files that may be needed (public and some others
1637 included by the public headers) by application developers are
1638 now copied to the ./includes directory. It does not copy any
1639 internal headers. Affected file Makefile.defines.pre and all
1640 Makefile.am's under lib/ and subdirs.
1642 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Do not change the ~/.silc directory's permissions automatically.
1645 Affected file irssi/src/silc/core/clientutil.c.
1647 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Do not cancel the protocol in silc_server_close_connection
1650 it might cause recursion. Now cancelled in the function
1651 silc_server_free_sock_user_data. Affected file silcd/server.c.
1653 * Fixed the silc_server_remove_clients_by_server to regenerate
1654 the channel keys correctly finally. Added also new function
1655 silc_server_remove_clients_channels to actually do it.
1656 Affected file silcd/server.c.
1658 * Fixed the silc_server_new_channel to not crash by giving
1659 wrong router to the new channel. Affected file is
1660 silcd/packet_receive.c.
1662 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1665 which is given as argument to the silc_client_alloc now.
1666 It can be used to configure the client and set various parameters
1667 that affect the function of the client.
1669 * The USERS command in server did not check whether the channel
1670 is private or secret. Affected file silcd/command.c.
1672 * Added new argument to the USERS command in protocol specification.
1673 The USERS command now can take the channel name as argument
1674 as well. Added support for this in client and server and
1675 updated the protocol specs.
1677 * Completed the GETKEY command in client. It can be now used
1678 to fetch also servers public key not only some clients.
1679 Affected files lib/silcclient/command[_reply].c.
1681 * Added silc_client_get_server to return server entry by the
1682 server name. Affected files lib/silcclient/silcapi.h and
1685 * Redefined the IDENTIFY command in protocol specification to be
1686 more generic. It now can be used to query information about
1687 any entity in the SILC Network, including clients, servers and
1688 channels. The query may be based either the entity's name
1689 or the ID. Added support for this in both client and server.
1691 Affected files silcd/command.c and lib/silcclient/command.c
1692 and command_reply.c.
1694 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1695 the _from_client and _from_server functions. Affected file
1698 * Added silc_client_get_channel_by_id_resolve to the file
1699 lib/silcclient/silcapi.h to resolve channel information by
1700 its ID. Added also silc_client_get_channel_by_id that
1701 does not resolve it from the server.
1703 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Added SilcServerEntry context into the client library
1706 to represent one server. The INFO command now allocates
1707 these to save the resolved server info. For now on the
1708 client library will also keep information about servers,
1709 connected and resolved with INFO.
1711 The INFO command now allocates the SilcServerEntry context
1712 and saves the server info there. The COMMAND_REPLY in
1713 the INFO now returns the parameters to application in
1714 same order as defined in the protocol specification.
1716 The entries are cached in the client->server_cache.
1718 * The INFO command is now issued after received the Client ID
1719 from the server. Affected file lib/silcclient/client.c.
1721 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1722 to the application as the mode changer might be server.
1723 It is guaranteed that NULL is not returned anymore to the
1724 application. Affected file lib/silcclient/client_notify.c.
1726 The ID Type is now also passed to the application so that
1727 it can check whether the returned entry is SilcClientEntry
1730 Added new function silc_client_get_server_by_id to return
1731 the server entry by ID. Affected files are the
1732 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1734 * Do not create the channel in the Irssi SILC Client when issuing
1735 the JOIN command but when received the sucessful JOIN command
1736 reply. Otherwise the channel might get created even though we
1737 could not join it. The Affected file is
1738 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1740 * Fixed a channel joining bug in router. The router must also
1741 check the channel modes, invite and ban lists etc. when serving
1742 the JOIN command sent by normal server. Affected file is
1743 silcd/command.c. The router now resolves the client's
1744 information from the server who sent the JOIN command if it
1745 does not know it, and processes the JOIN command only after
1748 * Changed the SilcCommandCb to take new argument; void *context2.
1749 Affected file lib/silccore/silccommand.h
1751 The second argument in the command callbacks in the server now
1752 includes the SilcServerCommandReplyContext if the command was
1753 called as pending command callback from the command reply.
1754 Otherwise it is NULL. When called as pending the status of the
1755 command reply will be checked and if it was erronous the
1756 error will be sent to the original sender of the command.
1757 This way the client always receives the error messages even
1758 though the server was actually the one who received the error
1759 when it resent the command to router, for example. Affected
1760 files silcd/command[_reply].[ch].
1762 * Fixed sending WHOWAS command's error message to client if
1763 the requested client could not be found. It was missing.
1766 * Changed the CMODE and CUMODE commands reply arguments in the
1767 protocol specification. The Channel ID is now sent in both
1768 of the commands to identify the channel. Implemented this
1769 new feature to the client and server. Affected files
1770 lib/silcclient/command_reply.c and silcd/command.c.
1772 * Made better checks for invite and ban lists in the JOIN
1773 command in server. Affected file silcd/command.c.
1775 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * The server now performs the incoming host IP/DNS lookup
1778 using the silc_socket_host_lookup and thus does not block
1779 the server anymore. Affected file silcd/server.c.
1781 * Completed the multi-thread support for SILC Scheduler in
1782 the lib/silcutil/silcschedule.c.
1784 * Fixed the configure.in.pre to detect the pthread correctly
1787 * Fixed a deadlock in silc_task_queue_wakeup in the file
1788 lib/silcutil/silctask.c.
1790 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Added new function silc_schedule_wakeup that is used in
1793 multi-threaded environment to wakeup the main thread's
1794 schduler. It needs to be used when a thread adds a new task
1795 or removes a task from task queues. After waking up, the
1796 scheduler will detect the task queue changes. If threads
1797 support is not compiled in this function has no effect.
1798 Implemented the wakeup mechanism to both Unix and WIN32
1799 systems. Affected files are lib/silcutil/silcschedule.[ch],
1800 lib/silcutil/unix/silcunixschedule.c and the
1801 lib/silcutil/win32/silcwin32schedule.c.
1803 * Added new function silc_task_queue_wakeup to wakeup the
1804 scheduler by the specified task queue. Affected file
1805 lib/silcutil/silctask.[ch].
1807 * The silc_socket_host_lookup_start now wakes up the scheduler
1808 after adding the timeout task. Affected file is
1809 lib/silcutil/silcsockconn.c.
1811 * The silc_socket_host_lookup is synchronous now if the threads
1812 support is not compiled in. However, the callback is still
1813 called asyncronously through the scheduler, anyway. Affected
1814 file lib/silcutil/silcsockconn.c.
1816 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1818 * Added new function silc_socket_host_lookup to perform
1819 asynchronous IP and FQDN lookups for the socket connection.
1820 Affected files lib/silcutil/silcsockconn.[ch].
1822 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1824 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1825 that may or may not compile the mutex support in.
1827 Changed the silc_mutex_alloc interface. It allocates the
1828 mutex now to the sent pointer and returns TRUE or FALSE.
1830 Affected file lib/silcutil/silcmutex.h.
1832 * Wrote the SILC Task Queue interface to support multi-threads.
1833 Affected file lib/silcutil/silctask.[ch].
1835 * Wrote the SILC Scheduler to support multi-threads. Affected
1836 file lib/silcutil/silcschedule.c.
1838 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1841 in lib/silcutil/win32/.
1843 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Defined SILC Mutex API and SILC Thread API and implemented
1846 them for Unix. Affected files are
1847 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1848 lib/silcutil/unix/silcunixmutex.c and
1849 lib/silcutil/unix/silcunixthread.c.
1851 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1853 * Fixed the silc_server_remove_clients_by_server's channel
1854 key re-generation. The hash table handling was incorrect
1855 and would not work with many channels. Affected file is
1858 * Fixed some memory leaks around the server code.
1860 * Rewrote the silc_server_get_users_on_channel to support IPv6
1861 based Client ID's. Affected file silcd/server.c.
1863 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1864 specification. However, a separate document must be written
1865 to define the detailed signing procedure and the payload
1866 associated with the flag. Defined the flag to the
1867 lib/silccore/silcchannel.h as well.
1869 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1871 * Changed the dynamic tables to static size tables in the
1872 lib/silccrypt/silchmac.c.
1874 * Removed GCC dependencies from the code. A patch by cras.
1876 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Do not show the error "Error receiving packet bla bla"
1879 in server if it really was not an error (-2 means that reading
1880 is pending). Affected file silcd/server.c.
1882 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Fixed a possible crash in silc_server_remove_clients_by_server
1885 in silcd/server.c. Fixed there also some memory leaks.
1887 * Fixed the silc_idlist_replace_client_id. It could replace
1888 wrong key in the hash table. Affected file silcd/idlist.c.
1890 * Do not check whether there are global users on the channel
1891 if the channel->global_users is FALSE. Affected functions
1892 silc_server_remove_from_one_channel and
1893 silc_server_remove_from_channels in silcd/server.c. Also,
1894 do not check if the removed client is local as we can be
1895 sure that global client was not removed from the channel
1896 and checking for global users is not needed.
1898 * The silc_server_remove_clients_by_server now re-generates
1899 the channel keys correctly for those channels that had
1900 clients removed from them. Affected file silcd/server.c.
1902 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Found the reason of random crashes in the server. We weren't
1905 ignoring the SIGPIPE signal (which can be sent in write())
1906 and it crashed the server. Affected file silcd/silcd.c.
1908 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1910 * Assure that sock->user_data is not NULL in the function
1911 silc_server_packet_send in silcd/packet_send.c.
1913 * Disconnect the remote connection if it could not be added
1914 to any ID lists in the server. The affected file is
1917 * Check in silc_server_packet_send[_real/dest] that the
1918 socket is not disconnecting and ignore the data if it is.
1919 Affected file silcd/packet_send.c.
1921 * Define inline to __inline on native WIN32 compilation.
1922 Affected file includes/silcwin32.h.
1924 * Added some explicit type casts for inline code since MSVC
1925 require them. Affected files lib/silcutil/silcbuffer.h,
1926 lib/trq/silcdlist.h and lib/trq/silclist.h.
1928 * Print warning in log files from now on if the packet
1929 decryption fails. Affected file silcd/server.c.
1931 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * Changed the `say' client operation's interface to accept
1934 new `type' argument to indicate the type of the message sent
1935 by the library. The application may filter the library's
1936 messages according the type. The affected file is the
1937 lib/silcclient/silcapi.h.
1939 * Added two new functions to lib/silcclient/silcapi.h:
1940 silc_client_del_client and silc_client_del_client_by_id.
1941 Affected file lib/silcclient/idlist.c.
1943 * Moved the clientincludes.h from includes/ to silc/ and
1944 serverincludes.h from includes/ to silcd/.
1946 * The modes for the CMODE and CUMODE are now passed as
1947 uint32 for application with COMMAND_REPLY. The affected
1948 file is lib/silcclient/command_reply.c.
1950 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * /WHOIS without arguments shows client's own information.
1953 Affected file lib/silcclient/command.c.
1955 * Changed PING to not accept any arguments. The specs
1956 says that client can ping only the connected server so
1957 requiring an argument is not needed. Affected file is
1958 lib/silcclient/command.c.
1960 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Fixed a fatal bug in private message sending and reception
1963 encryption and decryption when using private message keys.
1964 The implementation was incorrect and did not follow the
1965 specification. It causd that some of the message were
1966 lost since it did not use the sending and receiving keys
1967 as the protocol suggests. This has been fixed and will cause
1968 incompatibilities with older clients when sending private
1969 message encrypted with private message keys. Affected files
1970 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1971 and various other in Irssi SILC Client.
1973 Added `responder' boolean argument to the functions
1974 silc_client_add_private_message_key[_ske] to indicate when
1975 the key is added as responder or initiator of the key
1978 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1980 * Removed the silc_ske_check_version function and created
1981 a SilcSKECheckVersion callback. Added also a function
1982 silc_ske_set_callbacks that is now used to set all SKE
1983 callbacks. The callback functions are not given to
1984 the SKE functions anymore, but this function is used to
1987 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1989 * Added `silc_version' argument to the silc_client_alloc
1990 to define the version of the application for the library.
1991 The library will use the version string to compare it
1992 against the remote host's (usually a server) version
1993 string. Affected file lib/silcclient/silcapi.h
1995 * Added the KE protocol context to Key Agreement context
1996 in client library so that we can abort the SKE if it
1997 is in process when we get timeout. Affected file is
1998 lib/silcclient/client_keyagr.c.
2000 * Do not resolve the client ID forever if it returns in the
2001 first time that such client does not exist. This was done
2002 for example with private message. Affected file is
2003 lib/silcclient/client_prvmsg.c.
2005 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Do not add regex.h for WIN32. The affected file
2008 includes/silcincludes.h.
2010 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2011 not work yet 100%. It generates the DLL's automatically
2012 when compiling with --with-win32 under cygwin.
2014 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2016 * lib/contrib/regex.c is not compiled on WIN32.
2018 * Added silc_net_get_socket_opt function to the
2019 lib/silcutil/silcnet.h.
2021 * Added includes/silcwin32.h for WIN32 specific includes
2024 * Do not use ptime structure or any of the posix process
2025 functions on WIN32 in lib/silccrypt/silrng.c.
2027 * Added silc_gettimeofday to provide generic function
2028 for struct timeval on all platforms. Added the function
2029 to lib/silcutil/silcutil.h.
2031 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Moved the lib/silccore/silcsockconn.[ch] to the utility
2034 library as they clearly belong there. As a plus side we
2035 can make the actual socket connection routines platform
2038 Added also new generic function silc_socket_read and
2039 silc_socket_write (that used to be silc_packet_[read/write].
2040 The implementation of these are platform specific.
2042 * Added WIN32 specific routines of silc_socket_[read/write]
2043 to lib/silcutil/win32/silcwin32sockconn.c.
2045 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2047 * Added preliminary support for native WIN32 compilation under
2048 cygwin (using the -mno-cygwin option for GCC) to the
2049 ./configure.in.pre. The --with-win32 now prepares the
2050 compilation for native WIN32.
2052 * Rewrote the SILC Scheduler interface in the file
2053 lib/silcutil/silcschedule.h. The scheduler is now context
2054 based and does not have anymore any global static scheduler.
2055 Moved the Unix scheduler to the lib/silcutil/unix/ directory
2056 and created lib/silcutil/win32 directory for WIN32 based
2059 * Added Unix specific network routines to the
2060 lib/silcutil/unix/silcunixnet.c and the old
2061 lib/silcutil/silcnet.c includes now only generic routines.
2063 Added WIN32 specific network routines to the
2064 lib/silcutil/win32/silcwin32net.c.
2066 * Added Unix specific utility functions from the
2067 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
2069 * Added WIN32 SILC Scheduler to the file
2070 lib/silcutil/win32/silcwin32schedule.c. The code is of course
2073 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2075 * Do not handle JOIN notify in the server if the target client
2076 is not registered (idata->registered == FALSE). The affected
2077 file is silcd/packet_receive.c.
2079 * Update the nickrec->founder in event_cumode in the Irssi SILC
2080 client. Affected file irssi/src/silc/core/silc-channels.c.
2082 * Fixed the CUMODE_CHANGE notify handling in the server when
2083 server and router are announcing their clients on channels.
2084 Now the mode changes are saved and notified correctly. The
2085 affected file is /silcd/packet_receive.c.
2087 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
2088 They really did not replace the cache entry in the ID Cache.
2089 Now they do that. Affected file silcd/idlist.c.
2091 * Fixed the KICK notify handling in the Irssi SILC client to
2092 update the channel records so that the kicked client does not
2093 appear to be on the channel. The affected file is
2094 irssi/src/silc/core/silc-channels.c.
2096 * Always update the conn->current_channel when executing command
2097 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
2099 * Fixed the KILL notify handling in Irssi SILC client to remove
2100 the killed client on all channels.
2102 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Fixed the silc_parse_command_line to remove extra spaces
2105 from the start and end of the arguments. Affected file is
2106 lib/silcutil/silcutil.c.
2108 * Cancel and free any active protocol in the function
2109 silc_server_close_connection. Affected file silcd/server.c.
2111 * Cancel and free any active protocol in the function
2112 silc_client_close_connction. Affected file is
2113 lib/silcclient/client.c.
2115 * Do not execute the KILL command for clients that are in
2116 history (ie. they are not in the network). Affected file is
2119 * Fixed KILL notify handling, client does not crash anymore.
2120 Affected file irssi/src/silc/core/silc-channels.c.
2122 * Reduced the default packet buffer size from 2048 to 1024 in
2123 lib/silccore/silcpacket.c.
2125 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
2126 counter to the SKE context that is incresed when the SKE library
2127 performs async operation outside the library. If the outside
2128 process frees the SKE context and FREED status will be set
2129 and the library will detect after the sync operation that the
2130 libary is freed. The affected files are
2131 lib/silcske/silcske[_status].[ch].
2133 * Resolve the client entry information in the function
2134 silc_client_channel_message to assure that NULL pointer is not
2135 passed as client entry to the application. */
2137 * Fixed the task timeout calculation to assure that there is
2138 never negative timeouts. The affected file is
2139 lib/silcutil/silcschedule.c.
2141 * Fixed the channel user mode notification sending in server.
2142 It was sent point-to-point to the router (or to server by router)
2143 but it needs to be destined to a channel. The routines now
2144 supports sending the channel user mode notifys to the channels
2145 when announcing clients and channels. Affected files are
2146 silcd/server.c and silcd/packet_receive.c.
2148 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
2149 It did not actually replace the old channel entry in the cache.
2150 Affected file lib/silcclient/client_notify.c.
2152 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2154 * Fixed a possible crash in silc_packet_send_prepare. It now
2155 assures always that there is enough space in the buffer and
2156 at the tail area of the buffer (for MAC).
2158 Fixed the inbound buffer reallocation in silc_packet_read.
2159 It was old code and did not handle the reallocation correctly.
2162 The affected file is lib/silccore/silcpacket.c.
2164 * Fixed buffer overflow in silc_parse_nickname in the file
2165 lib/silcutil/silcutil.c.
2167 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * make install generates new server keys only if there is not
2172 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
2175 Added check that if the NOREPLY is set then we will not send
2176 the away message. This avoids infinite loop of away messages
2177 if both clients are away. The affected file is
2178 lib/silcclient/client_prvmsg.c.
2180 * Fixed client crash if /NICK was given without arguments.
2181 Affected file lib/silcclient/command.c.
2183 * Server does not send the invite list in INVITE command back
2184 to the client if the list was not altered. Added this notion
2185 to the protocol spec as well. Affected file silcd/command.c.
2187 Fixed possible crash in INVITE command by checking the
2188 value of silc_server_get_client_route command.
2190 * Fixed the INVITE notify type handling. The arguments are now
2191 taken in correct order and client does not crash. The affected
2192 file is irssi/src/silc/core/silc-channels.c.
2194 Removed the "Inviting xxx to channel" message from the
2195 client library away and let the application handle it.
2196 Affected file lib/silcclient/command.c. Added that message
2197 to Irssi SILC client's message formats.
2199 * Fixed CMODE command crash in client. It now checks the
2200 amount of arguments correctly and does not crash. The affected
2201 file is lib/silcclient/command.c.
2203 * Do not create new channel automatically in silc_channels_join
2204 but check whether the channel by that name already exists.
2205 Affected file irssi/silc/core/silc-channels.c.
2207 * Do not send the SERVER_SIGNOFF to router if the disconnected
2208 entity was the router. Affected file silcd/server.c.
2210 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
2211 SILC client as it was missing from there.
2213 Added the handling of the KICK notify to the Irssi SILC client
2214 as it was missing. Added "you have been kicked" message to
2215 Irssi SILC client's message modules formats.
2217 Added the handing of the KILL notify to the Irssi SILC client
2218 as it was missing. Added the kill message module formats
2221 The affected file is irssi/src/silc/core/silc-channels.c.
2223 * The router did not save the channel mode the server announced.
2224 Affected file silcd/packet_receive.c.
2226 * Fixed a possible crash in INFO command in server. If the
2227 server did not provide the server info it crashed. Affected
2228 file silcd/command.c.
2230 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Fixed the GETKEY command in the server to check also the
2233 global list. Otherwise the GETKEY would not work correctly
2234 in normal SILC server. Affected file silcd/command.c.
2236 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2238 * Fixed GETKEY crash, it crashed if the command did not succseed.
2240 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
2243 is now real and not just an macro interface to GMP.
2245 Removed the entire GMP from the source tree and imported new
2246 NSS MPI library instead. Reason for removing GMP is that it is
2247 extremely large and compiles extremely slow. The NSS MPI
2248 is only a few files and compiles in less than 10 seconds.
2249 The speed is also about the same as GMP. The MPI is imported
2250 to lib/silcmath/mpi.
2252 If the system has GMP installed we will still use the GMP.
2253 If it is not then the NSS MPI will be compiled.
2255 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Merged a long nickname (127 characters long) crash bugfix from
2258 Irssi CVS tree. Affected file irssi/src/core/misc.c.
2260 * Merged a freed memory reference bugfix from Irssi CVS tree.
2261 Affected file irssi/src/core/commands.c.
2263 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * Added the server's public key sving and verification to the
2266 server when performing the SKE. This was missing and the
2267 remote server's (or router's) public key was accepted without
2268 checking whether we have it previously or trust it at all.
2269 Affected file silcd/protocol.c.
2271 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Check in the silc_server_timeout_remote if protocol is active
2274 and make sure that the protocol's final callback is called so
2275 that all memory if freed. Affected file silcd/server.c.
2277 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * silc_server_whois_send_reply crashed the server if the nickname
2280 was 127 characters long. Affected file silcd/command.c.
2282 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Added sanity check to the silc_server_new_client. If the hostname
2285 is provided inside username then check that the provided hostname
2286 really is the same as the resolved one. If the hostname was not
2287 resolved then check it from the public key. Affected file is
2288 silcd/packet_receive.c.
2290 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
2291 if the server disconnected us and the connection is not valid
2292 anymore. Affected file irssi/src/silc/core/silc-channels.c.
2294 * Moved the silc_client_[chmode|chumode|chumode_char] away from
2295 the library to the lib/silcutil/silcutil.[ch].
2297 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Close log file after open. Affected file
2300 lib/silcutil/silclog.c.
2302 * Check whether sock == NULL in silc_client_send_packet and return
2303 if it is. Affected file lib/silcclient/silcclient.c.
2305 * Check rec->entry == NULL in the Irssi SILC Client before
2306 sending the channel message. Affecte file is
2307 irssi/src/silc/core/silc-servers.c.
2309 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Merged a splitted window bugfix from Irssi CVS tree. The
2312 affected file is irssi/src/fe-text/textbuffer-view.c.
2314 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
2315 It did not print nickname.
2317 * Improved the distributions system a bit.
2319 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2321 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2322 irssi/src/fe-text/gui-window.c.
2324 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2325 to in-active server. The affected file is
2326 irssi/src/silc/core/client_ops.c.
2328 * Resolve the client in USERS command reply if the entry does
2329 not have username resolved. The affected file is
2330 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2331 command to WHOIS command to really resolve stuff. The USERS
2332 is not used any more in any critical section so WHOIS can
2333 be used even though it might be slower than IDENTIFY.
2335 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2338 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Changed the protocol API a bit more consistent in the
2341 lib/silccore/silcprotocol.[ch].
2343 * Changed the following headers to ROBODoc format:
2345 lib/silccore/silcpayload.h
2346 lib/silccore/silcprotocol.h
2347 lib/silccore/silcsockconn.h
2349 All core library headers are now formatted.
2351 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2353 * Fixed a bug in Irssi SILC client; do not show that you are
2354 server/router operator if you really are not. Affected file is
2355 irssi/src/silc/core/client_ops.c.
2357 * Renamed silc_command_free_payload to silc_command_payload_free.
2358 Affected file lib/silccore/silccommand.h
2360 * Added silcmath.h to include the prototoypes of various routines
2361 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2364 * Changed the following headers to ROBODoc format:
2366 lib/silccore/silcchannel.h
2367 lib/silccore/silccommand.h
2368 lib/silccore/silcid.h
2369 lib/silccore/silcidcache.h
2370 lib/silccore/silcmode.h
2371 lib/silccore/silcnotify.h
2372 lib/silccore/silcpacket.h
2373 lib/silcmath/silcmath.h
2375 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Added checking to the server code not to start the server if
2378 ciphers and stuff are not configured properly. Affected files
2379 silcd/serverconfig.[h] and silcd/server.c.
2381 * Changed the layout of the header files of the public interfaces
2382 in the SILC libraries. The new layout supports ROBODoc
2383 documentation tool (and some others) so that it is easy to create
2384 a library reference manual. All the other headers and source
2385 code must still follow the CodingStyle document. Also source
2386 code must not include these ROBODoc stuffs, only the headers.
2387 Furthermore, all public interface headers must now be named
2388 by using `silc' prefix, example: silcapi.h, silccipher.h.
2389 Some files were renamed due to this. All the other headers
2390 must not be used as public interfaces. I will update the
2391 CodingStyle document later. Changed following headers, so far:
2393 lib/silcclient/silcapi.h
2394 lib/silccore/silcauth.h
2395 lib/silccore/silcprivate.h
2396 lib/silccrypt/silcdh.h
2398 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Removed silc_client_packet_send_flush from the client library
2403 as it is not needed. Affected file lib/silcclient/client.[ch].
2405 * Added printing of message of unresolved authentication method
2406 to the Irssi SILC client. Added it to the module formats.
2407 Removed the same message from the client library.
2409 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Added new distribution feature, DISTLABEL. Every distribution
2412 can define own preprocessor label that can be used in the
2413 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2414 file distributions, acconfig.h.pre and prepare.
2416 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Added Makefile.defines_int to include the actual definitions
2419 for Makefile.defines.in. Tested the new distribution system,
2420 created distributions and tested installation.
2422 * Added AWAY message printing to the Irssi SILC client. Added
2423 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2425 * Added SCONNECT command to call the SILC's CONNECT command.
2426 Cannot use CONNECT directly since Irssi uses that internally.
2427 Affected file irssi/src/silc/core/silc-servers.c.
2429 Added ACTION local command. It is same as ME command but takes
2430 the channel as mandatory argument.
2432 Rewrote some of the Irssi's help files to suite for SILC
2435 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Added Makefile.defines[.in] that should for now on be included
2438 in all Makefile.am file in the source tree. That file includes
2439 all common compilation definitions for SILC source tree.
2441 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Minor changes to the ./prepare script to change the package
2444 name according the distribution name to the configure.in.
2446 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Created new distribution system. Added file `distributions'
2449 that defines all the distributions that can be created out of
2450 the SILC source tree. The ./prepare script now reads that
2451 file to determine how to prepare the distributions. The
2452 first argument to the ./prepare is the name of the distribution
2453 and second is the version of the distribution. If given
2454 without arguments it creates the default (toolkit) distribution
2455 with the default version (defined in ./prepare).
2457 All Makefile.am files that are subject to the distributions
2458 are now named as Makefile.am.pre. These are ./Makefile.am
2459 and lib/Makefile.am. Others may be changed later.
2461 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2463 * Added invite list, ban list, some key management and connection
2464 error message printing to module formats in the Irssi SILC client.
2466 * Added new silc_client_set_away_message to set the away message
2467 that is back to the person who sent private message. The
2468 affected file lib/silcclient/silcapi.h and the
2469 lib/silcclient/client_prvmsg.c.
2471 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Fixed the private message sending in the Irssi SILC client,
2474 added local command KEY to the Irssi SILC client.
2476 Added key management and key agreement message formats to the
2477 irssi/src/fe-common/silc/module-formats.[ch].
2479 Added USERS (alias WHO) printing, server/router operator
2480 indication and LIST command printing to the module formats.
2482 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Fixed channel joining notify handling, cumode notify handling
2485 from Irssi SILC client.
2487 * Added SILC specific module-formats to the Irssi SILC client so
2488 that SILC specific message hilighting, colors etc is possible.
2489 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2491 Added channel mode, channel user mode, actions, notices,
2492 whois and whowas printing to the the module-formats.c.
2494 * Fixed a bug in channel deletion in the server. The channel
2495 is not left to the cache even if the channel founder auth mode
2496 is set when there are no users anymore on the channel. Affected
2497 file silcd/server.c.
2499 * The silc_net_localhost now resolves the entire hostname including
2500 the domain name. Affected file lib/silcutil/silcnet.c.
2502 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Changed the ask_passphrase client operation to be ascynchronous.
2505 It has now a completion callback and a context that the
2506 application must call after it has got the passphrase from
2507 the user. Affected files lib/silcclient/silcapi.h,
2508 lib/silcclient/protocol.c, lib/silcclient/command.c and
2511 Added SilcAskPassphrase callback that the application calls
2512 to deliver the passphrase to the library.
2514 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2515 The public key verification and especially a certificate
2516 verification is asynchronous procedure.
2518 Added new SILC_SKE_STATUS_PENDING status to indicate the
2519 request is pending and a callback will be called to finalize
2522 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2523 indicate that remote end did not send its public key (or
2524 certificate), even though we require it. Added check for this
2525 condition in the SKE. This was a security bug, now fixed.
2527 Defined new SilcSKEVerifyCbCompletion callback that is called
2528 when the verification process is completed.
2530 The affected files lib/silcske/silcske_status.h and
2531 lib/silcske/silcske.[ch].
2533 * Changed the verify_public_key client operation to be async
2534 as well. Defined SilcVerifyPublicKey callback that is used to
2535 indicate the success of the public key verification process.
2537 Changed the server and client to use the new async client
2540 * Changed the Irssi SILC client's internal scheduler to be called
2541 twice as many times as it used to be. As a result the client
2542 should be a bit faster now. Affected file is
2543 irssi/src/silc/core/silc-core.c.
2545 * Added support to Irssi SILC client of asynchronous public key
2546 verification and passphrase inquiry. Affected file is
2547 irssi/src/silc/core/silc-core.c.
2549 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Do not say "You have left channel %s" in client library.
2552 Moved it to the application. Affected files are
2553 lib/silcclient/command.c and silc/client_ops.c.
2555 * Fixed silc_client_get_clients. Command context was not
2556 duplicated and was freed memory in the callback. Affected
2557 file lib/silcclient/idlist.c.
2559 * Do not say "you are now talking..." on JOIN command in the
2560 client library. The appliation must handle it.
2562 * Do not say ".. changed topic to" in command reply in the
2563 client libary. The application must handle it.
2565 * Fixed TOPIC command sending in the client library.
2567 * Fixed a memory leak in silc_client_command_free in the file
2568 lib/silcclient/command.c.
2570 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Imported a modified version of Irssi client to the source tree.
2573 The Irssi will be used to create a new client called
2574 Irssi SILC. Imported to irssi/.
2576 Added silc_core_init_finish function to the Irssi. Affected
2577 file irssi/configure.in.
2579 A lot changes in the Makefile.ams around the irssi tree.
2581 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Do not rehash if the new size is same as the old size of the
2584 hash table, in the silc_hash_table_rehash*. The affected file
2585 lib/silcutil/silchashtable.c.
2587 * Replaced hash_table_del_by_context calls from the server
2588 (when channel->user_list and client->channels) to the
2589 hash_table_del as it is sufficient and faster.
2591 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Added silc_hash_table_list, silc_hash_table_get and the
2594 SilcHashTableList structure to provide an alternative way to
2595 traverse the hash table. The affected files are
2596 lib/silcutil/silchashtable.[ch].
2598 * Changed the server's idlist routines to use the hash table
2599 routines to optimize the code.
2601 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Replaced the client entry's `channel' list and channel entry's
2604 `user_list' list to hash tables for optimized lookup. Changed
2605 the code to use the hash table interface around the code.
2606 Affected file lib/silcd/idlist.[ch].
2608 * Added `auto_rehash' boolean argument to the function
2609 silc_hash_table_alloc to indicate whether the hash table should
2610 auto-rehash when it thinks is appropriate time. It will
2611 increase the hash table size if the there is twice as much
2612 entries in the table than the size of the table, and will
2613 decrease the size if there are twice as less entries than
2614 the size of the table.
2616 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2620 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * silc_idcache_purge_by_context deletes the entry now by context
2623 as it is supposed to do. Affected file lib/silccore/idcache.c.
2625 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2626 client is not anymore valid (WHOWAS givens the info) and not
2627 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2629 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Removed the `data' and `data_len' arguments from the ID Cache
2632 interfaces and added `name' argument. ID Cache does not handle
2633 anymore the binary data only a names associated with given ID.
2635 * When hashing a Client ID with silc_hash_id the entire ID is
2636 not hashed anymore, instead only the hash of the Client ID is
2637 hashed. This way we can access the Client ID from the cache
2638 with Client ID but with the hash of the ID (which is a hash of
2639 the nickname) as well without any difference in performance.
2641 Added also silc_idcache_find_by_id_one_ext to do one on one
2642 searching when we have the actual ID. Added also function
2643 silc_hash_client_id_compare. The affected files are
2644 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2646 * When hashing the name associated with a ID it is always done
2647 in lowercase. This way we can access the cache without worrying
2648 about case-sensitivity, even though, for example nicknames are
2651 * Fixed a bug in server with channel message sending. It put
2652 wrong ID type as destination ID. The affected file
2653 silcd/packet_send.c.
2655 * silc_idcache_del_by_context now deletes from all hash tables
2656 by context. Affected file lib/silccore/idcache.c.
2658 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Changed the client library to use the new ID Cache interface.
2661 Changes around the source tree.
2663 * Added silc_hash_table_rehash_ext to rehash with specific
2664 hash function. Affected file lib/silcutil/silchashtable.[ch].
2666 * Added silc_hash_string_compare to compare two strings in the
2667 hash table. Affected file lib/silcutil/silcutil.[ch].
2669 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Added new function silc_idcache_del_by_context into the
2672 lib/silccore/idcache.[ch].
2674 * Changed the server's ID list routines to use the new ID Cache
2675 interface. Changes around the source tree.
2677 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Added silc_hash_table_del[_by_context]_ext functions in to the
2680 lib/silcutil/silchashtable.[ch].
2682 Removed silc_hash_table_find_all* routines and added new
2683 silc_hash_table_find_foreach to replace them.
2685 Added silc_hash_table_replace_ext function as extended
2686 replacing function. Separated the simple hash table interface
2687 from the extended hash table interface in the file
2688 lib/silcutil/silchashtable.h.
2690 * Fixed minor bugs and changed it to use some of the new
2691 hash table functions in lib/silccore/idcache.c
2693 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * Added new function silc_hash_table_find_all to return all keys
2696 in the hash table by the specified key. As the hash table is
2697 collision resistant it also makes it possible to have several
2698 duplicate keys in the hash table. This function may be used to
2699 find all of the keys from the hash.
2701 Added user_context arguments to the SilcHashFunction,
2702 SilcHashCompare and SilcHashDestructor to deliver user specified
2705 Added new fuctions silc_hash_table_find[_all]_ext to do
2706 extended lookup with specified hash and compare functions and
2707 specified user contexts.
2709 Added new function silc_hash_table_add_ext to add the key
2710 with specified hash function and user context.
2712 Added new function silc_hash_table_foreach to traverse all
2713 entrys in the hash table. Added SilcHashForeach callback
2716 Added new function silc_hash_table_del_by_context to delete
2717 the entry only if the context associated with the key matches.
2719 Affected files are lib/silcutil/silchashtable.[ch].
2721 * Removed silc_hash_[server/client/channel]_id and added just
2722 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2723 silc_hash_id_compare to compare two ID's using as the hash table
2724 comparison function. Added also silc_hash_data to hash
2725 binary data and silc_hash_data_compare to compare it.
2727 * Removed silc_idlist_find_client_by_hash as it is not needed
2728 anymore. Affected file silcd/idlist.[ch].
2730 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2731 to use internally the SilcHashTable. The new ID Cache is a lot
2732 faster than the old one. Some of the ID Cache interface was also
2733 rewritten and obsolete and stupid functions were removed.
2735 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Added entry_count field to the SilcHashTable to keep the number
2738 of the entries in the table. Implemented the function
2739 silc_hash_table_rehash. Added new function
2740 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2742 Fixed a minor bug in silc_hash_table_free.
2744 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2745 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2746 into the lib/silcutil/silcutil.[ch].
2748 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Implemented a collision resistant hash table into the
2751 lib/silcutil/silchashtable[ch]. See the header and the source
2752 for the SilcHashTable API.
2754 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * Merged dotconf version 1.0.2 into lib/dotconf.
2758 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2760 * Do not compile anything in lib/silcsim/* if the SIM support
2761 is not enabled. The tree should now compile without problems
2764 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2766 * Compiled the SILC under cygwin. Compiled and tested briefly
2767 without problems. More tests needed. The SIMs didn't compile
2770 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2772 * Fixed possible crash in silc_get_username in the
2773 lib/silcutil/silcutil.c.
2775 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Fixed a va_arg in silc/client_ops.c.
2779 * Oops, RC5 routines were named AES and caused some problems
2780 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2782 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Added new SilcIDIP structure into the lib/silccore/id.h and
2785 replaced the old `ip' fields from all SILC ID's to that type.
2786 This is a step towards IPv6 support.
2788 The silc_id_get_len takes now the ID as an extra argument.
2789 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2790 both IPv4 and IPv6 based ID's.
2792 The affected files are lib/silccore/id.[ch] and other files
2793 around the tree using these routines.
2795 * Removed the ID length arguments in server from various
2796 silc_server_send_notify_* routines -> they are not needed
2799 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Fixed memory leak in silc_encode_pem_file in the file
2802 lib/silcutil/silcutil.c.
2804 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2806 * Check minor version as well in the SKE. Affected files are
2807 silcd/protocol.c and lib/silcclient/protocol.c.
2809 * Added --identifier option to the server so that an identifier
2810 can be when creating the public key for the server. Affected
2811 file is silcd/silcd.c.
2813 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2814 lib/silccrypt/silcpkcs.c.
2816 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Register default ciphers and stuff when using -C option with
2819 the server. Affected file sildc/silcd.c.
2821 * Put back the servers public key filename format, it is better
2822 than the new one. For now, the client keys are saved with the
2823 new filename format. The affected file silc/client_ops.c.
2825 * Implemented the Cipher API for the rest of the ciphers that
2826 did not implement it or implemented it the wrong way.
2828 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Register default ciphers and stuff when using the -S option
2831 in the client. Affected file silc/silc.c. Same also when
2832 creating new key pair with -C option.
2834 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Fixed the silc_verify_public_key client operation function to
2837 save the public keys differently. The fingerprint is now
2838 used as filename and not the hostname. This way also the
2839 client keys are saved uniquely and not with hostnames. The
2840 affected file is silc/client_ops.c.
2842 * Trimmed the silc_hash_fingerprint function to remove extra
2843 whitespaces from the end of the fingerprint. The affected
2844 file is lib/silccrypt/silchash.c.
2848 * Added silc_cipher_register_default function to register all
2849 default ciphers. It can be used when configuration files
2850 does not exist and the application does not want any specific
2851 ciphers in any specific order.
2853 The SilcDList is now used as silc_cipher_list dynamically
2854 allocated cipher list. Removed the static list all together
2855 and now all ciphers must be allocated to the dynamic list.
2856 The silc_cipher_alloc routine was changed to check only the
2859 All silc_cipher_* routines that used to return int returns
2862 The affected files lib/silccrypt/silccrypt.[ch].
2864 * The same thing was done to silc_hash_* as for silc_cipher_*
2865 routines. Affected files lib/silccrypt/silchash.[ch].
2867 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2868 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2869 Added also silc_pkcs_[un]register[_default] functions.
2870 Removed the data_context from the PKCS API.
2872 * Added silc_hmac_register_default function to register default
2873 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2874 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2875 to unregister all hmacs at once.
2877 * Register the default ciphers, hash functions, PKCSs and HMACs
2878 if client's configuration file does not exist. The affected
2881 * The client did not load the hash functions from the SIM
2882 modules at all. Added support for this. Affected file is
2883 silc/clientconfig.c.
2885 * When decoding public key with silc_pkcs_public_key_decode, check
2886 the supported algorithm only if PKCS are registered. Affected
2887 file lib/silccrypt/silcpkcs.c. The same was done with the
2888 silc_pkcs_private_key_decode.
2890 * Fixed the SILC List routines to keep the list always in order.
2891 It used to change the list's order when traversing the list but
2892 not it preserves the order. Affected file lib/trq/silclist.h.
2894 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * Added the client library to use the SilcSocketConnection's
2897 reference counter (by silc_socket_dup) to prevent the bug that
2898 the socket object may be freed underneath async operation.
2900 * The name resolv library checking fixes in the configure.in.pre.
2903 * Created new version of the protocol drafts for future
2904 development. The -03 drafts are the ones that will be changed
2905 in the trunk now and the -02 will remain as they are.
2907 * Send list of CUMODE notifys to the router when announcing
2908 the channel users to the router. Affected file silcd/server.c.
2909 If the router receiving channel founder CUMODE for a channel
2910 that already has channel founder it will send CUMODE notify
2911 to the sender to remove the channel founder rights from the
2912 announced client. Affected file silcd/packet_receive.c.
2914 * The CUMODE notify may now use Server ID as well as the entity
2915 who changes the mode. Updated protocool specs.
2917 * Updated INSTALL and README files.
2919 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * New web pages in the http://silc.pspt.fi. The pages was
2926 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2928 * Implemented the [DenyConnectin] config section in the server.
2929 Added silc_server_config_denied_conn to check whether incoming
2930 connection is denied. Affected file silcd/serverconfig.[ch].
2932 * Do not check the ports when checking the incoming configuration
2933 data if the port is 0, meaning any. Affected file is
2934 silcd/serverconfig.c.
2936 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2938 * Fixed buffer overflow in silc_string_compare in the file
2939 lib/silcutil/silcutil.c.
2941 * Fixed double free in silc_server_command_leave in the file
2944 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2946 * Fixed the version checking in the server. Affected file is
2949 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Fixed the configuration data fetching when accepting new
2952 connections in the server. Affected file silcd/server.c.
2954 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Added `sender_entry' argument to the function
2957 silc_server_packet_relay_to_channel so that we can check
2958 whether some destination actually belongs to the same route
2959 the sender belongs (ie, we must not resend the packet to the
2960 sender). Affected file silcd/packet_send.[ch].
2962 * Added `servername' field to the SilcClientEntry in the server
2963 to hold the name of the server where client is from. Affected
2964 file is silcd/idlist.h.
2966 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Moved the channel message encrypting in the router betwen
2969 router connections from silc_server_channel_message to the
2970 silc_server_packet_relay_to_channel since we want to check
2971 whether we have anybody channel before encrypting anything.
2972 Affected files silcd/packet_[receive/send].c.
2974 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Fixed the [AdminConnection] server config section to support
2977 multiple entries. Affected file silcd/serverconfig.c.
2979 * Added support into the server to check the validity of the
2980 incoming connection before executing any KE or authentication
2983 * The connection configuration is now saved to the KE and
2984 connection auth protocol contexts and not fetched anymore in
2985 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2987 * The local hosts listenning address and port is also resolved
2988 now when starting the server. We want to have the socket object
2989 to include the real address and port for the listener. Added
2990 new function silc_net_check_local_by_sock into the files
2991 lib/silcutil/silcnet.[ch].
2993 * Fixed a broadcast bug in server -> do not broadcast if we
2996 * Fixed a routing bug. Do not route broadcast packets ever.
2997 Broadcast packets must be processed always and not routed since
2998 they may be destined to some other host than yourself and thus
2999 would get routed without no good reason. Affected file is
3002 * Added function silc_server_config_is_primary_route to check
3003 whether primary router connection has been configured (a router
3004 configuration that we are initiating). If there is not, we
3005 will assume that there is only two routers in the SILC network
3006 and we will use the incoming router connection as our primary
3007 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3009 * Changed the order of the broadcasting. Broadcast _after_ the
3010 packet has been processed not before. Affected file is
3013 * Fixed a [ClientConnection] parsing bug. The port was never
3014 parsed correctly thus resulting to port 0. Affected file
3015 silcd/serverconfig.c.
3017 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3018 argument and did not set the broadcast packet flag. Affected
3019 file silcd/packet_send.c. Fixed same bug in the function
3020 silc_server_send_notify as well.
3022 * If we receive NEW_ID packet for our own ID in the server, ignore
3025 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Removed the nickname from the Private Message Payload.
3030 Updated the code and the protocol specs.
3032 * Updated protocol specs for submitting to the IETF.
3034 * Tweaked the Random Number Generator a bit. Affected file
3035 lib/silccrypt/silcrng.c. Exported a new function
3036 silc_rng_[global]_add_noise which can be used to add more
3039 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Do not parse packets with different timeout when protocol
3042 is active -> may cause problem with rekey. Affected file
3045 * When server receives signoff notify it must not create
3046 new channel key if the client is on any channels since the
3047 sender of the signoff notify will create it.
3049 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Added printing of error messages during SKE protocol from the
3052 failure packet sent by server during SKE. Affected file
3055 * Removed the client's failure_callback handling with timeout
3056 and handle it immediately when received.
3058 * The SKE library returned wrong type in SUCCESS and FAILURE
3059 packets. They must be 32 bit MSB not 16 bit MSB.
3061 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3063 * Ok, rewrote the logic of the re-key and now it seems to work.
3064 I tested it on high traffic with frequent re-keys without
3065 problems. Added hmac_receive (and renamed hmac to hmac_send)
3066 in SilcClientConnection in lib/silcclient/client.h and
3067 in SilcIDListData in silcd/idlist.h. Also, removed the
3068 SilcPacketParserContext's cipher and hmac fields as they are
3069 not needed anymore and actually caused some problems when
3070 the ciphers and hmac's changed underneath the packet parser.
3072 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3074 * If re-key protocol is active then process the incoming packets
3075 synchronously since we must assure that icoming packets encrypted
3076 with the old key is processed before the new keys is set to
3077 use. This is true other packets than for REKEY packets.
3078 Affected file silcd/server.c. The same was done to client library
3079 as well, affected file lib/silcclient/client.c.
3081 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Fixed bug in client and server to accept the force send if
3084 the packet is send from silc_[server/client]_packet_process
3085 function. Otherwise the packets are never delivered, oops.
3087 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Disable force sending of packets when REKEY protocol is active.
3090 We must assure that no packet is sent directly when rekey is
3091 performed. All packets must be sent through packet queue.
3092 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
3093 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
3094 function is silc_[server/client]_packet_send_real to check
3097 * Replaced the SIM paths from example config files to
3098 /usr/local/modules. Also, make install creates now
3099 /usr/local/silc/logs directory to hold all the SILC server
3102 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Made the configure.in.pre work on Solaris. Patch by salo.
3106 * Made all ciphers compatible with non-x86 machines. Defined
3107 CBC mode macros into lib/silccrypt/ciphers_def.h.
3109 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Fixed the make install.
3113 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * When MAC computation fails the silc_packet_decrypt returned 0
3116 even though it was supposed to return -1. Fixed this. The
3117 affected file is lib/silccore/silcpacket.c.
3119 * Do not replace the config files in /etc/silc (in make install)
3120 if they already exist. Affected file ./Makefile.am.
3122 * Do not send re-key packets immediately but through packet queue.
3123 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
3125 * Changed silc_net_check_host_by_sock to return FALSE if the
3126 IP/DNS could not be resolved. Though, it returns the IP address
3127 now even if it could not resolve it (but returns also FALSE).
3128 Affected file lib/silcutil/silcnet.[ch].
3130 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3132 * Added silc_pkcs_decode_identifier to decode the public key's
3133 identifier. Affected file lib/silccrypt/silpkcs.[ch].
3134 Added also silc_pkcs_free_identifier. Added also new context
3135 SilcPublicKeyIdentifier.
3137 * Added -S option to the silc client. It is used to dump the
3138 contents of the specified public key file.
3140 * Changed the PKCS api to return the public key length when
3141 setting the public key.
3143 * Fixed a fatal bug in the public and private key file loading.
3144 Affected file lib/silccrypt/silcpkcs.c.
3146 * Execute the packet parsing for client with zero (0) timeout
3147 if the protocol is active. Affected file silcd/server.c.
3149 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3151 * Made the key generation options to the silcd program. Added
3152 -C option, equivalent to client's option.
3154 * Added new [ServerKeys] config section to the server. It
3155 configures the server's public and private key.
3157 * Defined generic Public Key Payload into the protocol
3158 specification to send specific type of public keys and
3161 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
3162 public key or certificate.
3164 * Implemented the GETKEY command to the server and to the
3165 client library and on user interface.
3167 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Made preliminary `make install' work.
3171 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * Added SilcServerRekey context into silcd/idlist.h.
3175 * Added the PFS support as defined in the specification to the
3176 SKE protocol. Affected files lib/silcske/*.c.
3178 * Added `ske_group' field to the SilcServerRekey context to hold
3179 the number of the SKE group that is used with PFS in re-key.
3180 Affected file silcd/idlist.h.
3182 * Added PFS re-key support to the server. Affected file is
3185 * Added silc_protocol_cancel to cancel execution of the next
3186 state of the protocol. Affected file is
3187 lib/silccore/silcprotocol.[ch].
3189 * Added the re-key support with and without PFS to the client
3190 library. Re-key is performed once in an hour, by default.
3192 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
3193 Added silc_client_rekey_callback and silc_client_rekey_final.
3194 Affected files are lib/silcclient/protocol.[ch] and
3195 lib/silcclient/client.[ch].
3197 * Removed the `hmac_key' and `hmac_key_len' fields from the
3198 SilcClientConnection structure; not needed. Affected file is
3199 lib/silcclient/client.h.
3203 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Do not ask whether user wants to use the negotiated private key
3206 for private messages, just use it. Affected file is
3207 silc/local_command.c.
3209 * Added `send_enc_key' and `enc_key_len' fields to the
3210 SilcIDListData structure since they are needed in the re-key
3211 phase. Affected file is silcd/idlist.[ch].
3213 * Implemented the simple re-key protocol into the server.
3214 Affected files silcd/server.c and silcd/protocol.[ch]. The
3215 re-key will be performed once in an hour, by default.
3217 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
3218 Added silc_server_rekey, silc_server_rekey_callback and
3219 silc_server_rekey_final.
3221 * Removed Tunneled flag from the protocol. Updated the code
3222 and the specifications.
3224 * Adde `pfs' field to the SilcIDListData to indicate whether
3225 the PFS is to be performed in the re-key. Affected file is
3228 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
3231 int64 of at least the xintXX size. If void * is less that 4
3232 bytes uint32 * will be used. Defined bool as boolean.
3234 * Changed _ALL_ unsigned long and unsigned int to uint32,
3235 unsgined short to uint16 in the source tree.
3237 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
3238 not handle clients that has entry->data.registered == FALSE.
3239 They are not in the network anymore. Affected file is
3242 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Implemented the sending of the SERVER_SIGNOFF notify in the
3245 server. Affected file is silcd/server.c.
3247 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
3248 Added also silc_notify_payload_encode_args into the
3249 lib/silccore/silcnotify.[ch].
3251 * Implemented ther SERVER_SIGNOFF notify handling in the server.
3252 Affected file silcd/packet_receive.c.
3254 * Implemented the SERVER_SIGNOFF notify handling in the client
3255 library. Affected file lib/silcclient/client_notify.c. Also,
3256 implemnted the printing of the SERVER_SIGNOFF info to the
3257 application. Affected file silc/client_ops.c.
3259 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
3260 if the deleting was successful. Affected file silcd/idlist.[ch].
3262 * Added support for public key authentication in the connection
3263 authentication protocol in the client library. Affected file
3264 lib/silcclient/protocol.c.
3266 * Changed the server's silc_idlist_get_clients_by_* interface
3267 to support already allocated array so that new entries may be
3268 added to pre-allocated array. Affected file silcd/idlist.[ch].
3269 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
3270 and command replies.
3272 * All command reply functions in the server now calls the
3273 pending command callback even if error occured. This way the
3274 error will be delivered to the client as well. Affected files
3275 silcd/command.c and silcd/command_reply.c.
3277 * Fixed INFO command to return local server's info if no server
3278 was provided. Affected file lib/silcclient/command.c.
3280 * Removed RESTART command for good. Updated the code and the
3283 * Rewrote parts of the task system. It is a bit simpler now.
3284 Removed unsued task priorities. The affected files are
3285 lib/silcutil/silctask.[ch].
3287 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3289 * Moved the USERS printing from the library to the application.
3290 Affected files lib/silcclient/command.c and silc/client_ops.c.
3292 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3296 * Added channel key re-key support. The re-key is perfomed
3297 only by the router and is done once in an hour. Added `rekey'
3298 field to the SilcChannelEntry in the server. Affected files
3299 silcd/server.c and silcd/idlist.h.
3301 * Added silc_task_unregister_by_context into the file
3302 lib/silcutil/silctask.[ch].
3304 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added SILC_UMODE_GONE mode to indicate when the client is not
3307 present in the SILC network. Added also support to the local
3308 command AWAY that will set this mode. Added support of showing
3309 "xxx is gone" in WHOIS command. The USERS command shows the
3310 gone status as well.
3312 * Fixed setting server and router operator privileges in the
3313 server's UMODE command. Affected file silcd/command.c.
3315 * Merged the SKE KE1 and KE2 payloads into one payload. The
3316 new KE payload is equivalent to the old KE2 payload.
3318 Cleaned up the SKE Start Payload parsing. It now uses the
3319 simple buffer unformatting to do the parsing. A lot faster
3322 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3323 to the SKE that is used to indicate whether both of the SKE
3324 parties should perform authentication. By default only the
3325 responder performs authentication. By setting this flag also
3326 the initiator must do authentication. By default it is unset
3327 since in normal SKE case, client to server connection, only
3328 the responder should do authentication. When doing SKE between
3329 two clients both should perform authentication. Updated the
3330 code and the protocol specs.
3332 * A little fix to IDENTIFY command in the server. Search the
3333 client first by hash not nickname. Affected file is
3336 * Fixed the silc_client_close_connection to support closing
3337 the client to client connections wihtout deleting too much
3338 data. Affected file lib/silcclient/client.c.
3340 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3341 are received if protocol used to be active but is not anymore
3342 the application would crash due to NULL pointer dereference.
3343 Affected files silcd/server.c and lib/silcclient/client.c.
3345 * Added `hash' field to the SilcClientConnection to include
3346 the hash function negotiated in the SKE protocol.
3348 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3349 to set the channel founder authentication data. A client can
3350 claim the founder rights later by providing the authentication
3351 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3352 This way the channel founder can regain the channel founder
3353 privileges even it is left the channel. This works only on
3354 local server and the client must be connected to the same
3355 server to be able to regain the founder rights. Updated the
3356 protocol specs accordingly.
3358 Added support to the CMODE command in the client to set the
3359 founder auth data. Read the README to see how to set it.
3361 Added support to the CUMODE command to claim the founder
3362 rights. Read the README to see how to do it.
3364 Added support for the founder authentication to the Channel
3365 Entry in the server. Affected file silcd/idlist.h.
3367 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3368 server's CMODE command. Affected file silcd/command.c.
3370 * Added the following new functions into lib/silccore/silcauth.[ch]:
3371 silc_auth_get_method and silc_auth_get_data.
3373 * The server now saves the remote hosts public key to the
3374 SilcIDListData pointer. Affected file silcd/protocol.c.
3376 * The normal server now does not remove the channel entry from
3377 the cache if the founder authentication data is set. It used
3378 to remove it if the founder was the last one on the channel on
3379 the server and left the channel. The auth data is saved and
3380 if the channel is re-joined later the old entry is used with
3381 the old auth data. Affected files silcd/command_reply.c and
3384 * Removed the `pkcs' field from the SilcIDListData structure
3385 in the server; it is not used. Affected file silcd/idlist.h.
3387 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Fixed packet processing on slow links. Partial packets were
3390 never re-processed because the incoming data buffer was cleared
3391 by the application. Application must not directly clear the
3392 sock->inbuf, the packet processing routines handle it. Fixed
3393 this in client library and in server.
3395 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3397 * Fixed the WHOIS and IDENTIFY send reply function to really
3398 check whether to send list or just one entry. Affected file
3401 * Cleaned up the LEAVE command's channel key distribution. The
3402 affected file silcd/command.c.
3404 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3405 can enforce the channel mode as well. In that case the ID
3406 includes the ID of the server. The code now enforces the
3407 mode change if the router have different mode than the server.
3409 * The notify client operation with CMODE_CHANGE notify can now
3410 return NULL client_entry pointer if the CMODE was not changed
3411 by client. Application must check for this.
3413 * Added <Server ID> argument to INFO command to support server
3414 info fetching by Server ID.
3416 * Added silc_server_announce_get_channel_users to get assembled
3417 packets of channel users of the specified channel. Affected
3418 file silcd/server.[ch].
3420 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3421 was freed underneath the ID Cache.
3423 * Re-announce clients when the server received CHANNEL_CHANGE
3424 notify from the router. Affected file silcd/packet_send.c.
3426 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3428 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3429 crashed since it did not handle the fact that there is no cipher
3430 called "3" and didn't check the error condition. Now fixed.
3432 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3433 flag. It can be used to send message requests.
3435 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3437 * Implemented the RESTART command in the client.
3439 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3440 notice type messages. Added notice printing to the user
3443 * The channel keys are not re-generated if the channel's mode
3444 is PRIVKEY, ie private key on the channel exists. Affected
3445 files silcd/server.c and silcd/command.c.
3447 * Fixed a little bug in channel message delivery when channel
3448 private keys are set in the server. Affected file is
3449 silcd/packet_send.c.
3451 * Changed the setting on channel->on_channel = TRUE from the
3452 silc_client_save_channel_key to the JOIN command reply. The
3453 key payload is not received if the private channel key is set.
3454 Affected file lib/silcclient/command_reply.c and the
3455 lib/silcclient/client_channel.c.
3457 * When the CMODE_CHANGE notify is sent and the channel private
3458 key mode is removed the channel key must be re-generated in
3459 other cells as well. Added this support for the router in the
3460 silcd/packet_receive.c.
3462 * Added new local command NOTICE to send notice message on
3463 channel. Affected file silc/local_command.[ch].
3465 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Added new local command ME to the client. It is used to send
3468 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3469 some action. Affected file silc/local_command.[ch].
3471 * Changed channel_message and private_message client operations
3472 to deliver the message flags to the application. Added also
3473 the `flags' arguments to the silc_client_send_channel_message
3474 and silc_client_send_private_message functions. Affected file
3477 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Redefined the Private Message Payload to support private message
3480 keys and to support the new private message flags. Updated
3481 the protocol specs. Flags makes it possible to have for example
3482 CTCP style messages.
3484 * Added new type SilcPrivateMessagePayload and defined an API
3485 for it in the lib/silcclient/silcprivate.[ch].
3487 * Tested private message private keys successfully. Tested the
3488 private message key set, unset and list commands with the new
3491 * Redefined the Channel Message Payload to include the channel
3492 message flags (equal with private message flags) to support
3493 for example CTCP style messages.
3495 * Defined some of the message (for channel and private message)
3496 flags. Updated the protocol specs and added the flags to the
3497 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3499 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3501 * Added SilcKeyAgreementStatus type to the key agreement routines
3502 to indicate the current status and error if one occured.
3503 The status types are defined in the lib/silcclient/silcapi.h.
3505 * Added new local command KEY that is used to set and unset private
3506 keys for channels, set and unset private keys for private messages
3507 with remote clients and to send key agreement requests and
3508 negotiate the key agreement protocol with remote client. The
3509 key agreement is supported only to negotiate private message keys,
3510 it currently cannot be used to negotiate private keys for channels,
3511 as it is not convenient for that purpose.
3513 * Fixed a minor pending callback setting bug in the function
3514 silc_client_get_client_by_id_resolve, now the function works.
3515 Affected file lib/silcclient/idlist.c.
3517 * Added function silc_net_get_local_port to get local bound
3518 port by socket. Added to lib/silcutil/silcnet.[ch].
3520 * Added `sockets' and `sockets_count' fields to the SilcClient
3521 object. They hold the sockets of the listenning sockets in
3522 the client. Listenning sockets may be for example the key
3523 agreement server. Affected file lib/silcclient/client.[ch].
3524 Added functions the silc_client_add_socket and the
3525 silc_client_del_socket. They are exported to the application
3528 * Added ~./silc/clientkeys to support other client's public keys.
3530 * Renamed verify_server_key client operation to verify_public_key
3531 and added one argument to indicate the type of the connection
3532 (server, client etc.).
3534 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Added silc_server_connection_auth_request to handle the
3537 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3538 silcd/packet_receive.[ch].
3540 * Added silc_server_send_connection_auth_request into the
3541 silcd/packet_send.c to send the connection auth request packet.
3543 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3546 * Fixed the public key authentication in responder side in the
3547 server. The `auth_data' pointer includes the SilcPublicKey
3548 not the path to the public key. Affected file silcd/protocol.c.
3550 * Implemented the public key authentication in the initiator side
3551 in the server. Affected file silcd/protocol.c.
3553 * Removed the [RedirectClient] config section from the server
3554 configuration. Is not needed and I don't want to implement it.
3556 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3558 * Cleaned up the CMODE command in the server. It now works
3559 correctly and supports all the modes defined in the protocol.
3560 Affected file is silcd/command.c.
3562 * Added `hmac_name' field to the SilcChannelEntry in the server
3563 to hold the default HMAC of the channel. It can be set when
3564 creating the channel (with JOIN command). Affected files
3567 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3568 type to indicate the change of the current cipher and hmac
3569 on the channel. Client can safely ignore the <cipher> argument
3570 (if it chooses to do so) since the CHANNEL_KEY packet will
3571 force the channel key change anyway. The <hmac> argument is
3572 important since the client is responsible of setting the new
3573 HMAC and the hmac key into use.
3575 * Fixed the CMODE command in the client library as well.
3577 * Tested CMODE command in router environment successfully.
3579 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Show the version of the remote client (or server) when connecting
3582 to the server. It is logged to the log file. Affected file
3583 is silcd/protocol.c.
3585 * Fixed the KILLED notify handling in the client library. The
3586 client must be removed from all channels when receiving the
3589 Also, do not remove the client entry when giving the KILL
3590 command but when the KILLED notify is received.
3592 * Removed silc_idlist_find_client_by_nickname from the server.
3593 Not needed anymore. Affected files silcd/idlist.[ch].
3595 * Implemented the CHANNEL_CHANGE notify type handling to the
3596 server. Affected file silcd/server.c.
3600 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Added silc_server_send_notify_invite to send the INVITE
3603 notify between routers.
3605 * Implemented the INVITE command correctly to the server.
3607 * Implemented the INVITE notify type handling in the server.
3609 * Implemented the INVITE command to the client library and on the
3612 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Added function silc_server_get_client_resolve to find the
3615 client entry by ID from all ID lists and then resolve it
3616 (using WHOIS) if it cannot be found. Affected file is
3619 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Implemented the BAN command to the client library.
3623 * The JOIN command in the server now checks the invite list
3626 * Changed the silc_command_reply_payload_encode_va and the
3627 silc_command_payload_encode_va to support that if argument is
3628 NULL it ignores and checks the next argument. Affected file
3629 lib/silccore/silccommand.c.
3631 * Added silc_server_send_notify_ban to send the BAN notify
3632 type between routers.
3634 * Chaned the silc_notify_payload_encode to support that if
3635 argument is NULL it ignores and checks the next argument.
3636 Affected file lib/silccore/silcnotify.c.
3638 * Tested ban lists in router environment successfully.
3640 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Implemented BAN command to the server, in silcd/command.[ch].
3644 * Removed the BAN and INVITE_LIST modes from the CMODE command
3647 * Added function silc_string_match to regex match two strings.
3648 Affected files lib/silcutil/silcutil.[ch].
3650 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Redefined parts of the SilcChannelEntry in the server to support
3653 the new ban and invite lists.
3655 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Redefined the INVITE command. The same command can be used to
3658 invite individuals to the channel but also to manage the invite
3659 list of the channel (to add to and remove from the invite list).
3660 Updated the protocol specs.
3662 * Added new command SILC_COMMAND_BAN that can be used to manage
3663 the ban list of the channel. Updated the protocol specs.
3665 * Removed the channel modes: the SILC_CMODE_BAN and the
3666 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3667 in the CMODE command. The equivalent features are now available
3668 using INVITE and BAN commands. Updated the protocol specs.
3670 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3671 in the network about change in the current ban list. The notify
3672 type is not used by the client.
3674 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3675 support the invite lists.
3677 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * Added new function silc_string_regexify that converts string
3680 including wildcard characters into regex string that can
3681 be used by the GNU regex library. Added into the file
3682 lib/silcutil/silcutil.[ch].
3684 Added silc_string_regex_combine to combine to regex strings
3685 into one so that they can be used as one regex string by
3686 the GNU regex library. Added into the file
3687 lib/silcutil/silcutil.[ch].
3689 Added silc_string_regex_match to match two strings. It returns
3690 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3692 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3694 * Imported GNU regex to the soruce tree into lib/contrib.
3695 Fixed some compiler warning from the regex.c.
3697 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3699 * Fixed MOTD command in the server to work in router environment.
3701 * Fixed the MOTD command in the client library to support
3702 the server argument in the command.
3704 * Added `nickname_len' argument to the silc_idlist_add_client
3705 in the server, as the `nickname' argument may be binary data
3708 * Added silc_idlist_get_channels to return all channels from
3711 * Implemented LIST command to the server. Affected file is
3714 * Implemented the LIST command to the client library and on the
3717 * Added [<user count>] argument to the LIST command reply.
3718 With private channels the user count is not shown.
3720 * Updated TODO and README.
3722 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3724 * The client entry's data.registered must be TRUE even with
3725 global client entry on global client list. The data.registered
3726 is used to check whether the client is anymore in the network,
3727 for example with WHOWAS command so it must be valid.
3729 * Fixed the WHOWAS command in the server. It now actually works
3730 in router environment. Added function into silcd/command_reply.c
3731 silc_server_command_reply_whowas_save.
3733 * Added silc_idlist_purge function to the silcd/idlist.c
3734 to periodically purge the ID Cache.
3736 * Fixed INFO command in the server. It works now in router
3737 environment. Added <server name> argument to the INFO command
3738 reply. Updated the protocol specs.
3740 * Fixed minor bug in silc_idcache_purge to not purge if the
3741 expire value is zero.
3743 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3744 they were buggy because of the WHOWAS information.
3746 * Fixed local command MSG to handle the async resolving of
3747 the remote client properly. It used to fail the first MSG.
3748 Affected file silc/local_command.c.
3750 * Added `data_len' field to SilcIDCache context.
3752 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Update TODO. Todo in commands in the server.
3756 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3759 used by routers as broadcast packet to inform other routers
3760 about the changed user mode.
3762 Implemented the notify handling in the server. Affected file is
3763 silcd/packet_receive.c. Added the function
3764 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3766 * Added new generic Channel Payload and deprecated the New Channel
3767 Payload. The New Channel Payload is now the generic Channel
3770 * Added new argument `mode' to the silc_server_send_new_channel
3771 as it is required in the Channel Payload now.
3773 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3774 and created a new and real SilChannelPayload to represent the
3775 new generic Channel Payload. Implemented the encode/decode
3776 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3778 * Added silc_server_get_client_channel_list to return the list
3779 of channels the client has joined for WHOIS command reply.
3780 Affected file silcd/server.[ch].
3782 * Implemented the channel list sending in the WHOIS command reply
3783 in server and in the client.
3785 Implemented the channel list displaying on the user interface
3786 as well. Affected file silc/client_ops.c.
3788 * Added silc_channel_payload_parse_list to parse list of Channel
3789 Payloads. It returns SilcDList list of SilcChannelPayloads.
3790 Client for example can use this function to parse the list of
3791 channels it receives in the WHOIS command reply. The caller
3792 must free the list by calling silc_channel_payload_list_free.
3793 Affected files lib/silccore/silcchannel.[ch].
3795 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Added one new argument <user mode> to the WHOIS command reply
3798 to return the mode of the user in SILC. Updated the protocol
3801 Implemented it to the server and client.
3803 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3805 * Fixed the mode printing on the user interface on joining.
3806 Affected file silc/client_ops.c.
3808 * Implemented the UMODE command and user modes in general to the
3809 client library and to the user interface.
3811 * Implemented the UMODE command to the server.
3813 * The server now sends UNKNOWN_COMMAND error status if client sends
3814 unknown command. Affected file silcd/command.c.
3816 * All server commands now handle the command identifier the right
3817 way when sending the command reply to the client. The client can
3818 use to identify the command replies with the identifier.
3820 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Added silc_server_get_client_route to resolve the route to
3823 the client indicated by the client ID. Affected file is
3826 * Added silc_server_relay_packet as general function to relay
3827 packet to arbitrary destination. This deprecates functions
3828 like _send_private_message_key, _relay_notify etc. Affected
3829 file is silcd/packet_send.[ch].
3831 Removed silc_server_send_key_agreement,
3832 silc_server_send_private_message_key and
3833 silc_server_packet_relay_notify functions from the file
3834 silcd/packet_send.[ch].
3838 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3839 server. Affected file silcd/packet_receive.[ch].
3841 * Implemented the KILL command to the client. Implemented the
3842 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3843 Affected files lib/silcclient/command[_reply].c and
3844 lib/silcclient/client_notify.c. Implemented the KILL notify
3845 printing in the user inteface.
3847 * Fixed a lot silc_parse_nick memory leaks from the client
3848 library in the file lib/silcclient/command.c.
3850 * Changed the silc_server_send_notify_on_channels's `sender'
3851 argument from SilcSocketConnection to SilcClientEntry to
3852 check the sender as entry and not as connection object and not
3853 to send to the client provided as argument. The affected file
3854 is silcd/packet_send.[ch].
3856 * The notify packets that are destined directly to the client used
3857 to not to be processed by the server. Now changed that and the
3858 server processes all notify packets. After relaying the packet
3859 to the client the notify packet is processed in the server.
3861 * The silc_server_free_client_data now checks whether there is
3862 pending outgoing traffic for the client and purges the data to
3863 the network before removing the client entry.
3865 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3868 an client is killed from the SILC Network. Updated the protocol
3871 Added new function silc_server_send_notify_killed to the
3872 silcd/packet_send.[ch].
3874 * Added function silc_server_packet_relay_notify to relay notify
3875 packets that are destined directly to a client. In this case
3876 the server does not process the notify packets but merely relays
3877 it to the client. Affected file silcd/packet_send.[ch].
3879 Added also silc_server_packet_process_relay_notify to check
3880 whereto relay the notify. Affected file is
3881 silcd/packet_receive.[ch].
3883 * Implemented the KILL command to the server.
3887 * Added the backup schema desgined last fall to the protocol
3888 specs for everyone to see. The specification is in the
3889 *-spec-xx.txt draft and the packet type definitions for the
3890 backup routers is in *-pp-xx.txt draft. Thusly, added also
3891 new packet type SILC_PACKET_CELL_ROUTERS.
3893 * A big security problem in the implementation discovered. The
3894 signoff of an client did not cause new channel key generation
3895 which it of course should've done. The channel keys must be
3896 always re-generated when client leaves (or signoffs) the channel.
3897 The silc_server_remove_from_channels funtion now handles
3898 the channel key re-generation.
3900 * Added `sender' argument to the silc_server_send_notify_on_channels
3901 to not to send the client provided as argument. Affected file
3902 silcd/packet_send.[ch].
3904 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3906 * Implemented OPER and SILCOPER commands into the server and
3909 * Added silc_auth_verify and silc_auth_verify_data to verify
3910 the authentication directly from the authentication payload.
3911 It supports verifying both passphrase and public key based
3912 authentication. Affected file lib/silccore/silcauth.[ch].
3914 * Added `hash' field to the SilcIDListData structure. It is the
3915 hash negotiated in the SKE protocol. Affected file is
3918 * Slight redesigning of the SilcAuthPayload handling routines.
3919 Do not send SilcPKCS but SilcPublicKey as argument.
3921 * Implemented the public key authentication support to the
3922 serverconfig. The public key is loaded from the provided path
3923 and saved as authentication data to void * pointer. Thus,
3924 changed the unsigned char *auth_data to void *auth_data;
3926 * Fixed SHUTDOWN command to send the reply before the server
3927 is shutdown. :) Affected file silcd/command.c.
3929 * Fixed fatal bug in CONNECT command. The hostname was invalid
3930 memory and server crashed. Affected file silcd/command.c.
3932 * Fixed fatal bug in CLOSE command. The server_entry became
3933 invalid but was referenced later in the command. Affected file
3936 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Fixed fatal bug in failure packet handling. Server ignored
3939 the failure and thus crashed when it came.
3943 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3946 that the command may be executed only once in (about) 2 seconds.
3947 The old SILC_CF_LAG flag is same but allows command bursts up
3948 to five before limiting.
3950 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3951 server code. Various commands now includes the CF_LAG_STRICT
3952 flag to disallow any kind of miss-use of the command.
3954 * Fixed the silc_buffer_unformat to not to allocate any data
3955 if the length of the data is zero. It used to allocate the
3956 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3958 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Changed the format of AdminConnection configuration section
3961 in the server. Added username of the admin to the format.
3962 Affected files silcd/serverconfig.[ch].
3964 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3965 to return admin configuration data by host, username and/or
3968 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Implemented WHOWAS command to the server. Added the functions:
3972 silc_server_command_whowas_parse,
3973 silc_server_command_whowas_send_reply,
3974 silc_server_command_whowas_from_client and
3975 silc_server_command_whowas_from_server
3977 * Added <Client ID> argument to the WHOWAS command reply. Updated
3978 the protocol specs accordingly.
3980 * Implemented WHOWAS command and command_reply to the client
3983 Implemented the WHOWAS printing on the user interface.
3985 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Added new argument to the WHOWAS command reply, the real name.
3988 It is an optional argument. Updated the protocol specs.
3990 * Added SilcIDCacheDestructor callback that is registered when
3991 the SilcIDCache is allocated. The callback is called when
3992 an cache entry in the ID Cache expires, or is purged from the
3993 cache. Added into lib/silccore/idcache.[ch].
3995 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3996 to destruct the client entries when the cache entry expires.
3997 Other ID Cache's in server and in the client library ignores
4000 * If the ID Cache entry's `expire' field is zero then the entry
4001 never expires. Added boolean `expire' argument to the
4002 silc_idcache_add function in the lib/silccore/idcache.[ch].
4003 If it is TRUE the default expiry value is used.
4005 * Added silc_server_free_client_data_timeout that is registered
4006 when client disconnects. By default for 5 minutes we preserve
4007 the client entry for history - for WHOWAS command.
4009 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Added support to the server to enforce that commands are not
4012 executed more than once in 2 seconds. If server receives
4013 commands from client more frequently, timeout is registered
4014 to process the commands. Affected file silcd/command.c.
4015 Added new function silc_server_command_process_timeout.
4017 * Changed NICK_NOTIFY handling in client library to check that
4018 if the client's nickname was changed, so there is no need to
4019 resolve anything from the server.
4021 * Removed error printing from the WHOIS and IDENTIFY commands.
4022 If error occurs then it is ignored silently in the client library.
4023 The application, however, may map the received error to
4024 human readable error string. The application currently maps
4025 the NO_SUCH_NICKNAME error to string.
4027 * Made the command status message public to the application. Moved
4028 them from lib/silcclient/command_reply.c to
4029 lib/silcclient/command_reply.h. The application can map the
4030 received command status to the string with the
4031 silc_client_command_status_message function.
4033 * Added check to the server to check that client's ID is same
4034 as the Source ID in the packet the client sent. They must
4037 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4039 * Added dist-bzip hook to the Makefile.am to make bzip2
4040 compressed distributions.
4042 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Server now enforces the maximum length for the nickname and
4045 the channel as protocol specification dictates. 128 bytes for
4046 nickname and 256 bytes for channel name.
4048 * Moved the WHOIS printing to the application. The client libary
4049 does not print out the WHOIS information anymore, the application
4050 must do it. Renamed silc_client_command_reply_whois_print to
4051 the silc_client_command_reply_whois_save.
4053 The client's idle time is also sent to the application now, and
4054 the idle is shown on screen.
4056 * Added silc_client_command_reply_identify_save to save the
4057 received IDENTIFY entries.
4059 * Do not check for channel private keys in message sending and
4060 reception if the channel does not have the PRIVKEY mode set.
4061 Affected file lib/silclient/client_channel.c.
4063 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4065 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4066 just surfaced after chaning the JOIN procedure.
4068 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Added silc_client_get_clients_by_list to get client entries
4071 from Client ID list, that is returned for example by JOIN
4072 and USERS command replies. The application should use this
4073 function for example when JOIN command reply is received to
4074 resolve the clients already on the channel (library does not
4075 do that anymore as USERS command reply is not used in the JOIN
4076 procedure anymore). Affected files lib/silcclient/silcapi.h and
4077 lib/silcclient/idlist.c.
4079 * JOIN command reply and USERS command reply returns now SilcBuffer
4080 pointers instead of unsigned char pointers when returning
4081 the client list and mode list.
4083 * Added <Client ID> argument to the JOIN command reply, mainly
4084 for the server to identify for which client the command was
4085 originally sent. Updated protocol specs accordingly.
4087 * Added SilcDlist private_key pointer to the SilcChannelEntry
4088 in the client to support the channel private keys. Affected
4089 file is lib/silcclient/idlist.h.
4091 * Added SilcChannelPrivateKey argument to the function
4092 silc_client_send_channel_message so that application can choose
4093 to use specific private ke if it wants to. If it is not provided,
4094 the normal channel key is used, unless private keys are set.
4095 In this case the first (key that was added first) is used
4096 as the encryption key.
4098 * Implemented the support for channel private key handling.
4099 Implemented the following functions:
4101 silc_client_add_channel_private_key,
4102 silc_client_del_channel_private_keys,
4103 silc_client_del_channel_private_key,
4104 silc_client_list_channel_private_keys and
4105 silc_client_free_channel_private_keys
4107 Affected file lib/silcclient/client_channel.c.
4109 * Added the support for the private keys in the channel message
4110 sending and encryption and in the message reception and
4111 decryption. Affected funtions are
4112 silc_client_send_channel_message and silc_client_channel_message.
4114 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Added SKE's key verify callback to the client library's
4117 KE protocol context. Affected files lib/silcclient/protocol.[ch].
4119 * Removed the statement that server (or router) must send USERS
4120 command reply when joining to the channel so that the client
4121 knows who are on the channel. Instead, the client list and
4122 client's mode list is now sent in the JOIN command reply to the
4123 client who joined channel. This is better solution.
4125 * Added function silc_server_get_users_on_channel and function
4126 silc_server_save_users_on_channel to the silcd/server.[ch].
4128 * Removed function silc_server_command_send_users from the
4131 * Do not show topic on the client library anymore. The topic is
4132 sent in the command reply notify to the application and the
4133 application must show the topic now.
4135 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added client searching by nickname hash into the IDENTIFY and
4138 WHOIS commands in the server as they were clearly missing from
4139 them. Affected file is silcd/command.c.
4141 * Fixed a bug in private message receiving in the client library.
4142 The remote ID was freed and it wasn't supposed, now it is
4145 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Minor fix to the channel payload; allocate the data area, as it
4148 needs to be of specific length.
4150 * If the key agreement port is zero then the operating
4151 system will define the bound port. Affected files are
4152 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
4154 * Added new function silc_channel_payload_decrypt into the file
4155 lib/silccore/silcchannel.[ch].
4157 * Moved the channel message etc, check from silc_packet_decrypt
4158 to applications. The library calls now a generic
4159 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
4160 when the packet is either normal or special. This was done to
4161 allow more wide range of checking that was not allowed when
4162 the code was in library. Now applications can do virtually any
4163 checks to the packet and return to the library the decision how
4164 the packet should be processed. Affected files are
4165 lib/silccore/silcpacket.[ch].
4167 Added silc_server_packet_decrypt_check to the server and
4168 silc_client_packet_decrypt_check to the client library.
4170 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
4171 to send with specified source and destination information.
4173 * Channel message delivery between routers was broken after the
4174 channel key distribution was fixed earlier. The channel key
4175 was used be to distributed to other routers as well which is not
4176 allowed by the protocol. Now this is fixed and channel keys
4177 really are cell specific and the channel message delivery between
4178 routers comply with the protocol specification.
4180 * Fixed various commands in server to check also the global list
4181 for the channel entry and not just the local list. The affected
4182 file silcd/command.c.
4184 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added assert()s to buffer formatting and unformatting routines
4187 to assert (if --enable-debug) when error occurs. Affected
4188 file: lib/silcutil/silcbuffmt.c.
4190 * Changed to auto-reconnect to check whether the remote host is
4191 router and register the re-connect timeout if it is. It used
4192 to check that whether we are normal server, but router must do
4193 auto-reconnect with another router as well. Affected file
4196 * Removed the [<key len>] option from CMODE command as the cipher
4197 name decides the key length, nowadays. See the defined ciphers
4198 from the protocol specification.
4200 * Added [<hmac>] option to the CMODE command to define the HMAC
4201 for the channel. Added SILC_CMODE_HMAC channel mode.
4203 * Added [<hmac>] option for the JOIN command so that user can
4204 select which HMAC is used to compute the MACs of the channel
4207 * Added Hmac field to the Channel Message Payload. The integrity
4208 of plaintext channel messages are now protected by computing
4209 MAC of the message and attaching the MAC to the payload. The
4210 MAC is encrypted. Now, it is clear that this causes some
4211 overhead to the size of the packet but rationale for this is that
4212 now the receiver can verify whether the channel message decrypted
4213 correctly and also when private keys are set for the channel the
4214 receiver can decrypt the packet with several keys and check from
4215 the MAC which key decrypted the message correctly.
4217 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
4218 lib/silccrypt/silccipher.[ch].
4220 * Added silc_hash_len to return the digest length into the
4221 lib/silcrypt/silchash.[ch].
4223 * Rewrote parts of Silc Channel Payload interface in the
4224 lib/silccore/silcchannel.[ch]. The encode function now also
4225 encrypts the packet and parse function decrypts it.
4227 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Fixed a minor formatting bug in the SKE's key material processing.
4230 It actually might have processed the keys wrong way resulting
4233 * Redefined the mandatory HMAC algorithms and added new algorithms.
4234 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
4235 and hmac-md5 truncated to 96 bits. The mandatory is now
4236 hmac-sha1-96. Rest are optional (including the one that used
4237 to be mandatory). Rationale for this is that the truncated HMAC
4238 length is sufficient from security point of view and can actually
4239 make the attack against the HMAC harder. Also, the truncated
4240 HMAC causes less overhead to the packets. See the RFC2104 for
4243 * Added new [hmac] configuration section. The SKE used to use
4244 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
4245 is of course wrong. The official names that must be proposed in
4246 the SKE are the ones defined in the protocol specification
4247 (hmac-sha1-96 for example). The user can configure any hmac
4248 using any hash function configured in the [hash] section. At
4249 least, the mandatory must be configured.
4251 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
4253 * Added HMAC list to the SKE proposal list. It has now both
4254 hash algorithm list and HMAC list. This makes the protocol
4255 incompatible with previous versions. The SKE now seems to work
4256 the way it is supposed to work, for the first time actually.
4258 * Defined plain Hash algorithms to the protocol specification.
4261 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Implemented support for key agreement packets into the server.
4264 Added functions silc_server_key_agreement and
4265 silc_server_send_key_agreement. Other than these functions,
4266 server has nothing to do with this packet.
4268 * Added support for private message key packets into the server.
4269 Added functions silc_server_private_message_key and
4270 silc_server_send_private_message_key.
4274 * Changed the silc_[client|server]_protocol_ke_set_keys to be
4275 called in the protocol's final callback instead in the END
4276 protocol state. This makes a little more sense and in the same
4277 time in client we can use the same protocol routines for normal
4278 key exchange and to key agreement packet handling as well.
4280 * Added to both client's and server's KE protocol context the
4281 SilcSKEKeyMaterial pointer to save the key material. We will
4282 bring the key material to the protocol's final callback by doing
4283 this. The final callback must free the key material.
4285 * Added SKE's packet_send callback into client's KE protocol
4286 context so that the caller can choose what packet sending function
4287 is used. This way we can use different packet sending when
4288 doing normal SKE when doing key agreement packet handling (in
4289 the key agreement packet handling we do not want to encrypt
4292 * Implemented the responder side of the key agreement routines
4293 in the client. The client can now bind to specified port and
4294 accept incoming key negotiation. The key material is passed
4295 to the application after the protocol is over.
4297 * Implemented the processing of incoming Key Agreement packet
4298 in the client. Added function silc_client_key_agreement to
4301 * Implemented the intiator side of the key agreement routines
4302 in the client. The client can now initiate key agreement with
4303 another remote client. The key material is passed to the
4304 application after the protocol is over.
4306 * Created client_keyagr.c to include all the key agreement
4309 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
4310 SILC_TASK_CALLBACK except that it is not static.
4312 * Created client_notify.c and moved the Notify packet handling
4313 from the client.[ch] into that file.
4315 * Created client_prvmsg.c and moved all private message and
4316 private message key routines from the client.[ch] into that file.
4318 * Create client_channel.c and moved all channel message and
4319 channel private key routines from the client.[ch] into that file.
4321 * Changed silc_client_get_client_by_id_resolve to resolve with
4322 WHOIS command instead of IDENTIFY command, in the file
4323 lib/silclient/idlist.c.
4325 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Implemented the SKE's responder side to the Client library.
4329 * When FAILURE is received to the protocol do not trust it
4330 blindly. Register a timeout to wait whether the remote closes
4331 the connection as it should do it, only after that process the
4332 actual failure. This was changed to both client and server.
4334 * Added client_internal.h to include some of the structures
4335 there instead of client.h in lib/silcclient/.
4337 * Added function silc_task_unregister_by_callback to unregister
4338 timeouts by the callback function.
4340 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Some "Incomplete WHOIS info" errors has been appearing on the
4343 log files. Took away the entry->userinfo check from WHOIS
4344 reply sending. The entry->userinfo is now " " if client did not
4345 provide one. I thought this was fixed earlier but something
4346 is wrong still. Let's see if the error still appears.
4348 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Fixed a minor bug in the login when the channel key is
4351 re-generated in the server. It used to generate the key in
4352 wrong order and thus caused problems in the channel traffic.
4354 * Fixed a minor bug in channel key distsribution after
4355 KICK command. The key was not sent to the router even though
4358 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Added silc_ske_process_key_material_data as generic routine
4361 to process any key material as the SILC protocol dictates. The
4362 function is used by the actual SKE library but can be used by
4363 applications as well. This relates to the private message keys
4364 and the channel private keys since they must be processed the
4365 same way the normal SILC session keys. The protocol dictates
4366 this. Affected files: lib/silcske/silcske.[ch].
4368 Added also silc_ske_free_key_material to free the
4369 SilcSKEKeyMaterial structure.
4371 * Defined silc_cipher_set_key function to set the key for
4372 cipher without using the object's method function. The affected
4373 files: lib/silccrypt/silccipher.[ch].
4375 * Implemented silc silc_client_add_private_message_key,
4376 silc_client_add_private_message_key_ske,
4377 silc_client_del_private_message_key,
4378 silc_client_list_private_message_keys and
4379 silc_client_free_private_message_keys functions in the
4382 Added functions silc_client_send_private_message_key to send
4383 the Private Message Key payload and silc_client_private_message_key
4384 to handle incoming Private Message Key payload.
4386 * Added Cipher field to the Private Message Key payload to set
4387 the cipher to be used. If ignored, the default cipher defined
4388 in the SILC protocol (aes-256-cbc) is used.
4390 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Removed lib/silcclient/ops.h file.
4394 Redefined parts of the SILC Client Library API. Created new
4395 file silcapi.h that deprecates the ops.h file and defines the
4396 published Client Library API. Defined also private message key
4397 API and channel private key API into the file.
4399 This is the file that the application must include from the
4400 SILC Client Library. Other files need not be included by
4401 the application anymore.
4403 * Added new key_agreement client operation callback and also
4404 defined the Key Agreement library API for the application.
4406 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4409 is used by clients to request key negotiation between another
4410 client in the SILC network. If the negotiation is started it
4411 is performed using the SKE protocol. The result of the
4412 negotiation, the secret key material, can be used for example
4413 as private message key.
4415 Implemented the Key Agreement payload into the files
4416 lib/silccore/silauth.[ch].
4418 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Redefined ciphers for the SILC protocol. Added some new ciphers
4421 and defined the key lengths for the algorithms. Changed the
4422 code accordingly. The default key length is now 256 bits.
4424 * Fixed SKE key distribution function silc_ske_process_key_material
4425 when the key length is more than 128 bits. The default key
4426 length in SILC is now 256 bits.
4428 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4429 to indicate unsupported algorithm.
4431 * Renamed rijndael.c to aes.c and all functions as well.
4433 * Fixed a long standing channel key setting bug in client library.
4434 Weird that it has never surfaced before.
4436 * Fixed bug in channel deletion. If the entire channel is removed
4437 then it must also delete the references of the channel entry
4438 from the client's channel list as the client's channel entry and
4439 the channel's client entry share same memory.
4441 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Implemented CONNECT and SHUTDOWN commands in the client.
4445 * Implemented CLOSE command to the client.
4447 * Added the function silc_idlist_find_server_by_name into the
4448 files silcd/idlist.[ch].
4450 Added the function silc_idlist_find_server_by_conn into the
4451 files silcd/idlist.[ch].
4453 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4455 * DIE command was renamed to SHUTDOWN. Updated the both code
4458 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4459 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4461 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4464 * Added function silc_server_create_connection function to create
4465 connection to remote router. My server implementation actually
4466 does not allow router to connect to normal server (it expects
4467 that normal server always initiates the connection to the router)
4468 so the CONNECT command is only good for connecting to another
4471 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4474 or some other client was kicked from the channel.
4476 Implemented the handling of the notify type to both client
4479 Implemented silc_server_send_notify_kicked to send the KICKED
4480 notify. It is used to send it to the server's primary router.
4482 * Implemented the KICK command into server and client.
4484 * Added `query' argument to the silc_idlist_get_client function
4485 to indicate whether to query the client from server or not if
4488 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4489 to indicate that the client is not channel founder.
4493 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Removed the rng context from SilcPacketContext structure and
4496 changed that the packet routine uses the Global RNG API.
4498 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Added support for quit message that client can "leave" on the
4501 channel when it quits the SILC. It is ditributed inside the
4502 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4504 Added silc_server_free_client_data that will take the
4505 signoff message as argument.
4507 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4509 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Updated parts of the protocol specification to keep it up
4514 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4517 payloads in one packet.
4519 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4520 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4521 use now the new List flag.
4523 * Also deprecated the following packet types: REPLACE_ID,
4524 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4526 * Added list support for Notify packet in server.
4528 * Added silc_server_send_notify_channel_change to send the
4529 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4530 the silc_server_send_replace_id.
4532 * Added silc_server_send_notify_nick_change to send the
4533 NICK_CHANGE notify type. Deprecates the function
4534 silc_server_send_replace_id.
4536 * Added silc_server_send_notify_join to send the JOIN notify type.
4537 Deprecates the function silc_server_send_new_channel_user.
4539 * Added silc_server_send_notify_leave to send LEAVE notify type.
4540 Deprecates the function silc_server_send_remove_channel_user.
4542 * Added silc_server_send_notify_cmode and
4543 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4544 types. Deprecates the silc_server_send_set_mode function.
4546 * Added SERVER_SIGNOFF notify type to indicate that server has
4547 quit. This means that all clients on the channel from that
4548 server will drop. This can be also used when netsplit happens.
4550 Deprecated REMOVE_ID packet type since it is not needed anymore
4553 Added silc_server_send_notify_server_signoff to send the
4554 SERVER_SIGNOFF notify type. Deprecates the function
4555 silc_server_send_remove_id.
4557 Added also silc_server_send_notify_signoff to send the
4558 SIGNOFF notify type.
4560 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4561 SILC protocol from this day on. Changed the protocol
4562 specification as well.
4564 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4565 notify type. It is used between routers to notify about
4566 topic changes on a channel.
4568 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4571 * Partly updated the protocol specification to comply with the
4572 changes now made. It is still though a bit outdated.
4574 * The JOIN notify type now takes one extra argument <Channel ID>.
4575 The packet used to be destined to the channel but now the
4576 JOIN type may be sent as list thus it is impossible to
4577 destine it to any specific channel. By adding this argument
4578 it is again possible.
4580 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Added CREDITS file. The CHANGES and CREDITS file will appear
4583 in the distribution as well.
4585 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4588 types in the server's silcd/packet_receive.c.
4590 * Implemented CMODE and CUMODE to work in router environment.
4592 * Fixed minor encoding and decoding buglet from the
4593 lib/silccore/silcmode.c.
4595 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4598 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4600 * Changed all SilcConfigServer* and silc_config_server* to
4601 SilcServerConfig* and silc_server_config*, respectively.
4604 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Associated the ID (client or server ID) to the Authentication
4607 Payload to avoid any possibility of forging. Updated the
4608 protocol specification and the code accordingly.
4610 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * The RSA key length is now save to the RsaKey context in the
4613 key generation process in lib/silccrypt/rsa.c. The key length
4614 is now used to figure out the maximum size of the block allowed
4615 to be encrypted/signed.
4617 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4618 is equivalent to the silc_mp_mp2bin but does not allocate any
4621 * Changed silc_mp_mp2bin API to take length argument. If it is
4622 non-zero then the buffer is allocated that large. If zero, then
4623 the size is approximated using silc_mp_sizeinbase, which however
4626 * Created Global RNG API which is global RNG that application can
4627 initialize. After initializing, any routine anywhere in the
4628 code (including library) can use RNG without allocating a new
4629 RNG object. This was done to allow this sort of use of the
4630 RNG in code that has no chance to allocate RNG object. All
4631 applications currently allocate this and many routines in the
4632 library use this. Affected file lib/silccrypt/silcrng.[ch].
4634 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4635 it to use the Global RNG API.
4637 * Defined Authentication Payload into protocol specification that
4638 is used during SILC session to authenticate entities. It is
4639 used for example by client to authenticate itself to the server
4640 to obtain server operator privileges.
4642 Implemented this payload into the lib/silccore/silcauth.[ch].
4643 Implemented also routines for public key based authentication
4644 as the new protocol specification dictates.
4646 Moved definitions of different authentication methods from
4647 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4649 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4650 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4651 silc_pkcs_verify_with_hash functions into the file
4652 lib/silccrypt/silcpkcs.[ch].
4654 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * The client entry's userinfo pointer must be always valid.
4657 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4658 will fail since it requires the userinfo. Now, the userinfo
4659 is allocated as "" if actual userinfo does not exist. Actually,
4660 it must exist and it is totally Ok to drop client connections
4661 that does not announce the userinfo. However, we will make
4662 this workaround for now.
4664 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4665 to return the remote port by socket.
4667 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4670 SILC_SERVER_PENDING_EXEC and added an new macro
4671 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4672 data or when error occurs while processing the pending command.
4674 Added new argument `destructor' into silc_server_command_pending
4675 and to the SilcServerCommandPending object. This destructor is
4676 now called after calling the pending callback or if error occurs
4677 immediately. If error occurs the actual pending callback won't
4678 be called at all - only the destructor. The destructor may be
4679 NULL if destructor is not needed.
4681 All this applies for client library code as well. Similar
4682 changes were made there as well for the pending commands.
4684 In the client, the application must now allocate the
4685 SilcClientCommandContext with the silc_client_command_alloc
4688 * Added reference counter to the SilcServerCommandContext. Added
4689 function silc_server_command_alloc and silc_server_command_dup
4692 Same type of functions added to the client library for the same
4695 * Removed the cmd_ident from IDListData away since it is now
4696 global for all connections. It is the command identifier used
4697 in command sending and with pending commands. The affected file
4700 * Added reference counter to the SilcSocketConnection objecet to
4701 indicate the usage count of the object. The object won't be
4702 freed untill the reference counter hits zero. Currently only
4703 server uses this, and client ignores it. The client must be
4704 set to use this too later. The affected files are
4705 lib/silccore/silcsockconn.[ch]. Added also the function
4706 silc_socket_dup to increase the reference counter.
4708 This was mainly added because it is possible that the socket
4709 is removed underneath of pending command or other async
4710 operation. Now it won't be free'd and proper DISCONNECTING
4711 flags, etc. can be set to avoid sending data to connection that
4712 is not valid anymore.
4714 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4715 the connection. After that it sets SILC_SET_DISCONNECTED.
4716 It is, however, possible that the socket data is not still freed.
4717 The silc_server_packet_process now checks that data is not
4718 read or written to connection that is DISCONNECTED. The socket
4719 get's freed when the reference counter hits zero.
4721 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Changed the client operation API: channel_message operation's
4724 `sender' is now the client entry of the sender, not the nickname
4725 and the `channel' is the channel entry, not the channel name.
4727 In the private_message operation the `sender' is now also the
4728 client entry of the sender not the nickname.
4730 Affected file is lib/silcclient/ops.h and all applications
4731 using the client operations.
4733 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Moved the calling of ops->connect() from connect_to_server_final
4736 into receive_new_id functin since that is the point when the
4737 client is actually allowed to send traffic to network. The
4738 affected file is lib/silcclient/client.c.
4740 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4743 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4744 (if needs broadcasting) instead of broadcasting the packets one
4745 by one which would make a burst in the network traffic.
4747 * Added `broadcast' argument to the functions in silcd/server.[ch]
4748 silc_server_create_new_channel[_with_id] to indicate whether
4749 to send New Channel packet to primary router.
4751 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Added new function into the silcd/server.[ch] files:
4754 silc_server_create_new_channel_with_id to create new channel with
4755 already existing Channel ID.
4757 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4758 lib/silccore/silcpacket.h. This packet is used t send list of
4759 Set Mode payloads inside one packet. Server uses this to set
4760 the modes for the channels and clients on those channels, that it
4761 announced to the router when it connected to it. The protocol
4762 specification has been updated accordingly.
4764 * The silc_server_new_channel did not handle the packet coming
4765 from normal server as it normally does not send that. However,
4766 when it announces its channels it does send it. Implemented
4767 the support for that.
4769 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4770 into the file lib/silccore/id.h.
4772 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Fixed memory leaks in the functions silc_idlist_del_client,
4775 silc_idlist_del_channel and silc_idlist_del_server in the file
4776 silcd/idlist.c. All of those leaked like a sieve.
4778 * Fixed some small memory leaks in the client's function
4779 silc_client_notify_by_server.
4781 * Added functions into silcd/server.c: silc_server_announce_clients,
4782 silc_server_announce_channels and silc_server_announce_server.
4783 These functions are used by normal and router server to announce
4784 to its primary router about clients, channels and servers (when
4785 router) that we own. This is done after we've connected to the
4788 These functions effectively implements the following packet types:
4789 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4790 and SILC_PACKET_NEW_ID_LIST.
4792 * Added new functions into the silcd/packet_receive.[ch]:
4793 silc_server_new_id_list, silc_server_new_channel_list and
4794 silc_server_new_channel_user_list to handle the incoming
4795 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4797 * Added support of changing Channel ID in the function
4798 silc_server_replace_id. If the server that announces a channel
4799 to the router already exists in the router (with same name but
4800 with different Channel ID), router is responsible to send
4801 Replace ID packet to the server and force the server to change
4802 the Channel ID to the one router has.
4804 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4805 client that the Channel ID has been changed by the router. The
4806 normal server sends this to the client. Client must start using
4807 the new Channel ID as the channel's ID.
4809 Implemented handling of this new type into lib/silcclient/client.c
4810 into the function silc_client_notify_by_server.
4812 * Added new function silc_idlist_replace_channel_id into the files
4813 silcd/idlist.[ch] to replace the Channel ID.
4815 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Call silc_server_command_identify_check always when processing
4818 the IDENTIFY command in silcd/command.c
4820 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4823 send keepalive packets. The packet can be sent by clients,
4824 servers and routers.
4826 Added function silc_socket_set_heartbeat into the file
4827 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4828 If not set, the heartbeat is not performed. The actual
4829 heartbeat is implemented in the low level socket connection
4830 library. However, application is responsible of actually
4833 Added silc_server_send_heartbeat to send the actual heartbeat
4834 packet into silcd/packet_send.[ch]. Server now performs
4835 keepalive with all connections.
4837 * Added silc_task_get_first function into lib/silcutil/silctask.c
4838 to return the timeout task with shortest timeout. There was a bug
4839 in task unregistration that caused problems. TODO has been
4840 updated to include that task system must be rewritten.
4842 * The client library will now resolve the client information when
4843 receiving JOIN notify from server for client that we know but
4844 have incomplete information.
4846 * Rewrote parts of silc_server_remove_from_channels and
4847 silc_server_remove_from_one_channel as they did not remove the
4848 channel in some circumstances even though they should've.
4850 * Encryption problem encountered in server:
4852 The LEAVE command used to send the Channel Key packet to the
4853 router immediately after generating it. However, the code
4854 had earlier sent Remove Channel user packet but not immediately,
4855 ie. it was put to queue. The order of packets in the router
4856 was that Channel Key packet was first and Remove Channel User
4857 packet was second, even though they were encrypted in the
4858 reverse order. For this reason, MAC check failed. Now, this
4859 is fixed by not sending the Channel Key packet immediately but
4860 putting it to queue. However, this is more fundamental problem:
4861 packets that are in queue should actually not be encrypted
4862 because packets that are sent immediately gets encrypted
4863 actually with wrong IV (and thus MAC check fails). So, packets
4864 that are in queue should be encrypted when they are sent to
4865 the wire and not when they put to the queue.
4867 However, the problem is that the current system has not been
4868 designed to work that way. Instead, the packet is encrypted
4869 as soon as possible and left to the queue. The queue is then
4870 just purged into wire. There won't be any fixes for this
4871 any time soon. So, the current semantic for packet sending
4874 o If you send packet to remote host and do not force the send
4875 (the packet will be in queue) then all subsequent packets to the
4876 same remote host must also be put to the queue. Only after the
4877 queue has been purged is it safe again to force the packet
4880 o If you send all packets immediately then it safe to send
4881 any of subsequent packets through the queue, however, after
4882 the first packet is put to queue then any subsequent packets
4883 must also be put to the queue.
4885 Follow these rules and everything works fine.
4887 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added new function silc_server_remove_clients_by_server to
4890 remove all client entries from ID list when the server connection
4891 is lost. In this case it is also important to invalidate all
4892 client entires as they hold the invalid server entry. This
4893 fixes fatal bug when server has lost connection and will reconnect
4896 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Made some sanity checks to silc_server_daemonise like to check
4899 whether the requested user and group actually exists.
4901 * Added sanity check to SKE's silc_ske_responder_finish to check
4902 that the public and private key actually is valid.
4904 * Invalidate the client's nickname when receiving Replace ID
4905 packet and the Client ID is being replaced. This means that the
4906 server will query the nickname if someone needs it (client)
4909 * Sort the ID Cache in client library when the ID Cache data
4910 has changed (needs sorting).
4912 * Do not allow for SILC client to create several connections to
4913 several servers. The client does not support windows right now
4914 and generating multiple connections causes weird behaviour.
4916 Irssi-silc client does support windows and can handle several
4917 connections without problems, see: www.irssi.org and SILC plugin.
4919 * Fixed some places where client was added to the IDList. The
4920 rule of thumb is following (in order to get everything right):
4921 If the client is directly connected local client then the
4922 `connection' argument must be set and `router' argument must be
4923 NULL to silc_idlist_add_client function. If the client is not
4924 directly connected client then the `router' argument must
4925 bet set and the `connection' argument must be NULL to the
4926 silc_idlist_add_client function.
4928 * The funtion silc_server_packet_send_local_channel actually did
4929 not check whether the client was locally connected or not. It
4930 does that now. Fixed a bug related to LEAVE command.
4932 * Fixed Remove Channel User payload parsing bug in server's
4933 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4935 * The server's silc_server_save_channel_key now checks also the
4936 global ID list for the channel as it might not be in the local
4937 list. Fixed a bug related to LEAVE command.
4939 * Is this the end of the [<unknown>] buglet that has been lurking
4940 around for a long time? A little for loop fix in server's
4941 silc_server_command_whois_parse that is used by both IDENTIFY
4942 and WHOIS command. At least, this was a clear bug and a cause
4943 of one type of [<unknown>] buglet.
4945 * WHOIS and IDENTIFY commands call the function
4946 silc_server_command_[whois/identify]_check function even if
4947 we are not router server.
4949 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Added --with-gmp configuration option. If set the GMP
4952 is always compiled in the SILC source tree. If not set then
4953 it is checked whether the system has the GMP3 installed. If
4954 it has then the GMP won't be compiled (the system's headers
4955 and library is used), if it doesn't have it then the GMP is
4956 compiled in the SILC source tree.
4958 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Changed RSA private exponent generation to what PKCS #1
4961 suggests. We try to find the smallest possible d by doing
4962 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4963 not security fix but optimization.
4965 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Added new config entry [Identity] to fork the server and run
4968 it as specific user and group. A patch from Bostik.
4970 * Imported Dotconf configuration library into lib/dotconf.
4971 This will be used to create the SILC configuration files later.
4972 It will appear in the distsribution after this commit.
4974 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * A big code auditing weekend happening. Auditing code for
4977 obvious mistakes, bugs and errors. Also, removing any code
4980 Removed files for being obsolete:
4982 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4983 inline in the file lib/silcutil/silcbuffer.h)
4985 o lib/silcutil/silcbufutil.c (the header has inline versions)
4987 Changed code to fix possible error conditions:
4989 o The buffer formatting routines now check that the destination
4990 buffer really has enough space to add the data. This applies for
4991 both buffer formatting and unformatting
4992 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4993 unformatting was changed to accomodate following rules:
4994 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4995 sent to the function while XXX_*STRING will not allocate or copy
4996 the data into the buffer. Instead it sets the pointer from the
4997 buffer into the pointer sent as argument (XXX_*STRING used to
4998 require that the pointer must be allocated already). This change
4999 makes this whole thing a bit more consistent and more optimized
5000 (note that the data returned in the unformatting with XXX_*STRING
5001 must not be freed now). The routines return now -1 on error.
5003 o Tried to find all code that use buffer_format and buffer_unformat
5004 and added return value checking to prevent formatting and
5005 especially unformatting errors and possible subsequent fatal
5008 o Changed ske->x and ske->KEY to mallocated pointers in
5009 lib/silcske/silcske.h. Fixed possible data and memory leak.
5011 o Added return value checking to all *_parse* functions. Fixed
5012 many memory leaks as well.
5014 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5015 so that buffer overflows would not happen. All code now also
5016 checks the return value as it can fail.
5018 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Added reconnection support to server if the normal server looses
5021 its connection to the router (for example if router is rebooted).
5022 The server performs normal reconnection strategy implemented
5023 to the server. Affected file silcd/server.c.
5025 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Added new packet type SILC_PACKET_SET_MODE that is used to
5028 distribute the information about changed modes (for clients,
5029 channels and clients channel modes) to all routers in the
5030 network. Updated the protocol specification accordingly.
5032 Added functions into silcd/packet_send.c and
5033 silcd/packet_receive.c: silc_server_send_set_mode,
5034 silc_server_set_mode.
5036 Added new files silcmode.[ch] into lib/silccore that implements
5037 the encoding and decoding of Set Mode Payload. Added new type
5038 SilcSetModePayload. Moved the definitions of different modes
5039 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
5041 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Oops, a little mistake in server's connection authentication
5044 protocol. The protocol is not ended with FAILURE but with
5045 SUCCESS if the authentication is Ok. :) Affected file is
5048 * Implemented NICK_CHANGE notify handling in server in the file
5049 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
5050 the local clients on the channel. After the changing nickname
5051 in router environment snhould work and the [<unknown>] nickname
5052 should appear no more.
5054 The silc_server_replace_id function that receives the Replace ID
5055 payload now sends the NICK_CHANGE notify type also in the file
5056 silcd/packet_receive.c
5058 * Changed WHOIS and IDENTIFY command to support the maximum amount
5059 of arguments defined in protocol specs (3328 arguments). This
5060 fixed a bug that caused problems when there were more than three
5063 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Added extra parameter, command identifier, to the
5066 silc_client_send_command so that explicit command identifier
5069 Changed that ID list routines uses specific command identifier
5070 when sending WHOIS/IDENTIFY requests to the server so that they
5071 can be identified when the reply comes back.
5073 Affected files lib/silcclient/command.[ch],
5074 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
5076 * Added `sender' argument to silc_server_packet_send_to_channel
5077 to indicaet the sender who originally sent the packet to us
5078 that we are now re-sending. Ignored if NULL. Affected file
5079 silcd/packet_send.[ch].
5081 * Added some server statistics support in silcd/server_internal.h
5082 SilcServerStatistics structure and around the server code. Also
5083 send some nice statistics information when client is connecting
5086 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Fixed channel ID decoding in server's JOIN command reply in
5089 silcd/command_reply.c
5091 * Fixed braodcasting of replace ID payload to not to send it if
5092 we are standalone server in silcd/packet_receive.c.
5094 * Fixed all channel message sending routines to not to send
5095 packets to clients that has router set, since they are routed
5096 separately in the same function earlier. Affects file
5097 silcd/packet_send.c and all channel packet sending functions.
5099 * In USERS reply, res_argv[i] are not allocated, the table
5100 is allocated. Thus changed that free the table, not its
5103 * In server's whois_check and identify_check if the client is
5104 locally connected do not send any WHOIS commands - they are not
5107 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Fixed some minor bugs in client when sending WHOIS command. The
5110 arguments was in wrong order.
5112 * Removed statis function add_to_channel from server in
5113 silcd/command.c that was previously used with the joining but
5116 * Tested USERS command in router environment successfully with two
5117 routers, two servers and two clients.
5119 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Reorganized the USERS command and command reply in client library
5122 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
5123 When the command is given by user we register a pending command
5124 callback that will reprocess the command after the reply has been
5125 received from the server. When reprocessing the packet we then
5126 display the information. Thus, the USERS information is displayed
5127 now in the command callback instead of in the command reply
5128 callback. The processing of the command is same as previously
5129 when server has sent the command reply in the JOINing process.
5131 * Added to USERS command in silcd/command_reply.c to join the client,
5132 we didn't use to know about, to the channel after we've created
5133 a client entry for it. Also, for clienet we did know already still
5134 check whether it is on the channel or not and add it if not.
5136 * Removed silc_server_command_join_notify as the function and its
5139 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5141 * Changed the client's pending command handling to the same as the
5142 server's pending command handling. It is also now possible to
5143 execute command reply functions from other command reply
5144 function as the function callbacks for commands and command
5145 replies are one and same. The pending commands are not static
5146 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
5147 in client connection context. Thus, pending commands are server
5148 connection specific as it is convenient.
5150 Changed the function silc_client_command_pending and
5151 silc_client_command_pending_del and added new function
5152 silc_client_command_pending_check. Removed the
5153 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
5156 * Added cmd_ident, current command identifier, to the client
5157 connection context in lib/silcclient/client.h to keep track on
5158 command identifiers used in command sending. Client's command reply
5159 function handling now supports the mandatory command identifiers.
5161 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
5162 funtions in client to fully support pending command callbacks.
5164 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
5165 as one of the arguments to the application in the command reply
5168 * NOTE: The FORWARDED flag is depracated. It used to be depracated
5169 before first releasing SILC but came back. Now it is removed again
5170 and should come back nomore. The FORWARDED flag was used only
5171 by the JOINing procedure by forwarding the command packet to router.
5172 Now, the JOINing procedure has been changed to more generic (due
5173 to various router environment issues) and FORWARDED is not needed
5174 anymore for anything. The protocol specification is yet to be
5177 Now, removed silc_server_packet_forward from server and the flag
5178 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
5180 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Renamed NAMES command to USERS command. The NAMES was named that
5183 due to historical reasons. Now it is renamed. Also, rewrote
5184 parts of the USERS command. The nickname list is not sent anymore
5185 by the server. Only Client ID and mode lists are sent in the USERS
5186 command. Changed this also to the protocol specification.
5188 The client now resolves the names and stuff after it receives
5189 the USERS list from the server when joining to the channel.
5191 * WHOIS and IDENTIFY commands has been changed to support multiple
5192 Client ID's per command. One can now search for multiple users
5193 in the network by sending only one WHOIS or IDENTIFY command.
5194 Changed the code and the protocol specifications.
5196 * Removed silc_server_command_identify_parse and changed that IDENTIFY
5197 uses silc_server_command_whois_parse to parse the request. */
5199 * If normal server, do not parse the WHOIS and IDENTIFY requests
5200 before sending it to the router. Saves some time.
5202 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Fixed JOIN command on client library. Wrong number of arguments
5205 used to crash the client.
5207 * Added silc_server_channel_has_global function to check whether
5208 channel has global users or not.
5210 * Added silc_server_channel_has_local function to check whether channel
5211 has locally connected clients on the channel.
5213 * The silc_server_remove_from_one_channel now checks whether the
5214 channel has global users or not after given client was removed from
5215 the channel. It also checks whether the channel has local clients
5216 on the channel anymore. If it does not have then the channel entry
5217 is removed as it is not needed anymore.
5219 * The silc_server_notify now checks on JOIN notify whether the joining
5220 client is one of locally connected or global. If it is global then
5221 the channel has now global users on the channel and that is marked
5222 to the channel entry. Also, it now saves the global client to
5223 global list who is joining and JOINs it to the channel. This is
5224 for normal server, that is.
5226 Changed silc_server_send_notify_on_channel,
5227 silc_server_packet_relay_to_channel and
5228 silc_server_packet_send_to_channel check if we are normal server
5229 and client has router set (ie. global client) do not send the
5230 message to that client, as it is already routed to our router.
5232 * Implemented LEAVE notify type handling in silc_server_notify
5235 * Tested LEAVE command in router environment successfully. Tested
5236 with two routers, two servers and two clients.
5240 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
5242 * Implemented SIGNOFF notify type handling in silc_server_notify
5245 * silc_server_remove_id now removes the client entry from all channels
5246 it has joined and thusly sends SIGNOFF notify type.
5248 * Rewrote the NAMES list generation in server by removing two excess
5249 loops. The lists are created now inside one loop.
5251 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * silc_server_remove_channel_user checks now also global list
5254 for channel and client.
5256 * silc_server_new_channel_user checks now both local and global
5257 list for channel and client. Fixed a bug in client id decoding.
5258 Used to decode wrong buffer.
5260 * silc_server_channel_message checks now both local and global
5261 list for channel entry.
5263 * Tested channel joining (hence JOIN) in router environment
5264 successfully. Tested with two routers, two servers and two
5267 * Tested channel message sending in router environment successfully.
5269 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added silc_server_save_channel_key into server.[ch] to save the
5272 received channel key in Channel Key payload processing. It is
5273 also used in JOIN command reply handling.
5275 Equivalent function silc_client_save_channel_key added into
5276 client.[ch] into client library.
5278 * Changed JOIN command reply to send information whether the channel
5279 was created or not (is existing already) and the channel key
5280 payload. Changed protocol specs accordingly.
5282 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
5283 the request was sent by ID and not by nickname. Crashed on
5286 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
5289 now correctly save the received data.
5291 * silc_server_free_sock_user_data now notifies routers in the
5292 network about entities leaving the network.
5294 At the same time implemented functions silc_server_remove_id
5295 and silc_server_send_remove_id to receive and send REMOVE_ID
5296 packets. The packet is used to notify routers in the network
5297 about leaving entities. The ID removed will become invalid in
5300 * Added function silc_idlist_del_server into server. Removes and
5301 free's server entry from ID list.
5303 * silc_server_private_message function now checks, if we are router,
5304 that the destination ID really is valid ID, naturally.
5306 * In router when NEW_ID packet is received (for new client) the
5307 hash of the Client ID is saved in the ID Cache but the
5308 client->nickname is set to NULL, instead of putting the hash
5311 IDENTIFY command now also checks that client->nickname must be
5312 valid. If it is not if will request the data from the server who
5313 owns the client. Added new function
5314 silc_server_command_identify_check.
5316 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
5317 to set the command to already allocated Command Payload.
5319 * Tested private message sending in router environment with two
5320 routers, two servers and two clients. Fixed minor bugs and now
5323 * Fixed segfault from client's NAMES command. Used to crash if
5326 * Forwarded packets must not be routed even if it is not destined
5327 to the receiver. Changed server code comply with this.
5329 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5331 * Added `require_reverse_mapping' boolean value to ServerParams
5332 structure. If TRUE (not default) the server will require that
5333 the connecting host has fully qualified domain name.
5335 If the reverse mapping is not required and hostname could not be
5336 found the IP address is used as hostname.
5338 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Implemented version string checking to both client and server.
5341 The check is incomplete currently due to the abnormal version
5342 strings used in development version of SILC.
5344 * Changed all command functions in server to use the new
5347 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Changed char *data to unsigned char *data in ID Cache system to
5350 support binary data as ID Cache data. Changed code to support
5351 binary data in lib/silccore/idcache.c.
5353 * Renamed silc_server_packet_relay_command_reply to
5354 silc_server_command_reply as it is normal packet receiving
5355 function. Rewrote the function to accept command replys for
5356 servers and not only for clients.
5358 * Mark remote router always as registered server if we are connecting
5359 to it. Otherwise, commands sent by the router to us are ignored.
5361 * All ID List find routines now returns the ID Cache Entry pointer
5362 as well if requested.
5364 * WHOIS command works now in router environment, tested with two
5365 routers, two servers and two clients.
5367 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5368 in router environment (as it is almost equivalent to WHOIS) but
5369 hasn't been tested thoroughly. Added new functions:
5371 silc_server_command_identify_parse
5372 silc_server_command_identify_send_reply
5373 silc_server_command_identify_from_client
5374 silc_server_command_identify_from_server
5376 * Disabled route cache adding because adding two different ID's with
5377 same IP replaces the old cache entry thus giving wrong route.
5378 The entry->router->connection is always the fastest route anyway
5379 so route cache may not be needed. Of course, new routes maybe
5380 established after receiving the ID when the entry->router->connection
5381 might not be anymore the most optimal.
5383 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5385 * Add route cache for received ID for fast routing.
5387 * Added silc_server_packet_route to route received packet on router
5388 that is not destined to us.
5390 * Renamed silc_server_get_route to silc_server_route_get.
5392 * Added id_string and id_string_len fields into SilcServer to
5393 include encoded ServerID for fast comparing without excess
5394 encoding of the ID's.
5396 * Cleaned up WHOIS command on server side. Added following static

5402 silc_server_command_whois_from_client
5403 silc_server_command_whois_from_server
5405 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5406 arguments in command replies. All command functions should be
5407 updated to use this macro.
5409 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Minor typo fixes on command reply handling on server.
5413 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added silc_server_command_add_to_channel internal routine to add
5416 the client to the channel after router has created the channel and
5417 sent command reply to the server.
5419 * Added generic silc_server_send_command to send any command from
5422 * Use static buffer with ID rendering instead of duplicating data.
5424 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Fixed a channel user mode bug when joining to a channel server gave
5427 everybody channel founder rights, oops.
5429 * We mark ourselves as the router of the incoming server connection
5430 if we are router ourselves. This way we can check in some packet
5431 sending functions whether it is locally connected server. For
5432 incoming router connections we put NULL.
5434 * For router sending packets locally means now always sending the
5435 packet cell wide; to local clients and local servers. For normal
5436 server sending packet locally means sending it to only local
5439 * Fixed the JOIN command to really work in router environment. If the
5440 channel is created it is always created by the router. Router is
5441 also responsible of making the initial joining to the channel,
5442 sending JOIN notify to the sending server and distributing
5443 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5444 does not exist server doesn't do anything else but forward the
5445 command to the router which performs everything.
5447 * Added silc_server_send_channel_key function to send the Channel Key
5450 * Added silc_server_create_channel_key to create new channel key. The
5451 channel key is now re-generated everytime someone joins or leaves
5452 a channel, as protocol dictates. Note: channel->key_len is the
5455 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5458 packet_receive.[ch] to separate packet sending and receiving
5459 routines. The server.[ch] now includes everything else including
5460 actual packet processing (writing and reading data) and other
5463 Renamed silc_server_private_message_send_internal to
5464 silc_server_send_private_message. The routine is still though
5465 used only to relay private messages as server does not send
5466 private messages itself.
5468 Renamed silc_server_new_channel to silc_server_create_new_channel
5469 and added new function sicl_server_new_channel that handles the
5470 incoming New Channel packet. Added also new sending function
5471 silc_server_send_new_channel to send New Channel Payload.
5473 * Added new function silc_server_notify to process incoming notify
5474 packet to the server/router. Server may then relay the notify
5475 to clients if needed.
5477 * Added new function silc_server_new_channel_user to process incoming
5478 New Channel User packet. Router will redistribute the packet and
5479 send JOIN notify to its local clients and locally connected servers
5480 if needed. Normal server will send JOIN notify to its local client
5481 on same channel when received this packet. Added also corresponding
5482 sending function silc_server_send_new_channel_user to sent the
5485 * Added boolean route argument to send_notif_to_channel and
5486 packet_send_to_channel functions to attempt to route the packet
5487 if it is TRUE and send only locally if it is FALSE.
5489 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5491 * silc_server_replace_id now broadcasts the received replace ID
5492 packet if it is not broadcast packet already. The router must
5493 broadcast to inform other routers about changed ID.
5495 * Added backpointer to server's router into SilcServer context in
5496 silcd/server_internal.h.
5498 * Fixed silc_server_packet_broadcast to send correct broadcast
5501 * The channel key is now distributed to the local client as soon
5502 as it is received from the router (in router environment) so that
5503 no other packet may be sent for the channel until client has
5506 * silc_server_remove_channel_user now broadcasts the received
5507 Remove Channel User packet if it is not broadcast packet already.
5508 The router must broadcast to inform other routers about removed
5511 * Added users field into SilcPacketContext that is a reference count
5512 of the context. One can increase the reference count by calling
5513 silc_packet_context_dup which is now changed to just increase the
5514 reference count instead of duplicating the data. The reference
5515 count is decresed by calling silc_packet_context_free that will
5516 free the data after the reference count hits zero.
5518 For now on the packet context and everything allocated into it
5519 (including the raw packet from network) must be freed by calling
5520 the new silc_packet_context_free function. Added also new function
5521 silc_packet_context_alloc that must be used now to allocate the
5522 context. This also means that if a routine is asynchronous from
5523 silc_[client/server]_packet_parse_type the packet context must
5524 be duplicated by calling silc_packet_context_dup. Otherwise it
5525 gets free'd after silc_[client/server]_packet_parse_type returns.
5526 Also, one must remember that if packet is duplicated then its
5527 reference count must be decresed by calling the free function as
5528 many times as it was duplicated.
5530 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5531 from both client and server.
5533 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Made joining to a channel working in router environment.
5537 * Cleaned up JOIN command on server side and create function
5538 silc_server_command_join_channel internal routine to make the
5541 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Changed silc_command_pending list to SilcDList. Also, added
5544 `ident' field to SilcServerCommandPending structure to identify
5545 the reply and to call correct callback.
5547 Added silc_server_command_pending_check function to replace the
5548 corresnponding macro. The silc_command_pending list is not
5551 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5552 to set identifier to previously allocated Command Payload. It
5553 is used to set identifier for command when resending Command
5556 * Added silc_command_payload_encode_payload to encode Command
5557 Payload buffer from SilcCommandPayload structure.
5559 * Added silc_argument_payload_encode_payload to encode Argument
5560 payload buffer from SilcArgumentPayload structure.
5562 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Changed WHOIS command to support router connection on server side.
5565 The whois request is always sent to router unless the server is
5566 standalone server. After server has received the reply from the
5567 router will it send the reply to the client.
5569 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5570 broadcast received broadcast packet. The function is used only
5571 by router. The broadcast packet is always sent to the router's
5574 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5575 render given ID to printable string, for log files for example.
5577 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Made basic router to router connections working. At least they
5580 can now connect to each other but nothing really works the way
5581 they are supposed - yet.
5583 * Added new initiator token to RouterConnection configuration
5584 file in silcd/serverconfig.[ch]. It is used to tell whether we
5585 are the initiator to the remote router or whether we'll expect
5586 the other end to connect.
5588 * Moved registering of listener task to silc_server_init, hence
5589 the server starts listenning as soon as it is run, even if it
5590 does not have connections to other routers. Let's see how well
5593 * Changed default connection retry timeouts for more suitable in
5596 * Removed cipher and such arguments from silc_idlist_add_client
5597 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5598 Added new function silc_idlist_add_data to add the keys and stuff
5601 * Added SilcIDListData structure and added it to SilcClientEntry
5602 and SilcServerEntry as their first field in the structure. This
5603 way we can explicitly cast the ID entries to the SilcIDListData
5604 structure and get common data for the entries. In past, we had
5605 to first check what type of connection it is and then cast it to
5606 correct ID entry type. Now, we can directly cast the opaque
5607 pointer to the SilcIDListData (no matter what ID entry it actually
5608 is) and get the data needed.
5610 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5613 in some circumstances even if threre were timeout tasks, though not
5614 IO tasks, but tasks anyway. Now fixed.
5616 * Defined SilcServerConnection structure to hold connection specific
5617 stuff about directly connected servers and routers. The definition
5618 is currently in silcd/server_internal.h. I thought about having
5619 a bit more important role fro this struct but for now it is used
5620 only when connecting to other server (or router actually).
5622 * Added connecting retry support in server when connecting to
5623 router(s). The retry feature implement exponential backoff
5624 algorithm. Also, added SilcServerParams structure to hold default
5625 parameters for server. For now, it include these retry settings
5626 and are hard coded. After server is moded to be as Silc Server
5627 Library this structure will be more important.
5629 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Changed client librarys channel->clients table to SilcList and
5632 changed code accordingly.
5634 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Changed client's channel table to SilcList and changed code
5637 accordingly. Also changed SilcChannelClientEntry to include back-
5638 pointer to the channel so that client entry can use that structure
5639 as list as well and we have fast cross-reference to the channel.
5640 This change dramatically decreased the complexity of channel
5641 handling with client entry and vice versa (removed one extra
5642 loop when searching for channel entry from many functions).
5644 * Changed server->sim from table to SilcDList and changed code
5647 * NAMES command can now be used from user interface. It will show
5648 the user list on the channel, neatly.
5650 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5651 Code now saves realname of the user if it becomes available.
5653 * Renamed configure.in to configure.in.pre and made ./prepare
5654 script to automatically add correct version string to
5655 configure.in which it creates from configure.in.pre.
5657 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * NAMES command reply now shows users mode with the nickname when
5662 * Moved silc_client_ch[u]mode[_char] functions from
5663 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5664 place sucks, they are utility functions and should be in some
5667 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5669 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5672 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added TRQ (efficient deque and list library) into lib/trq. This is
5677 a very good list library that is currently used in the SILC. Defined
5678 SilcList API over the library because I didn't like the API very
5679 much. See lib/trq/silclist.h for the API and examples of how to
5680 use the API. Fixed various places in the code to use the new
5681 SilcList API. The SilcList is meant for lists that has a structure
5682 already defined as a list. It is not suitable to add just some
5683 context to the list (in TRQ, the context is the list actually).
5685 So, I defined SilcDList that can be used for the purpose where
5686 predefined list structure does not exit. This can be used as
5687 such list. Now some context just can be added to the SilcDList.
5688 Currently this list is not used in the SILC just yet, though there
5689 are a lot places where this can replace dynamically allocated
5690 tables and I will fix these places, later, to use SilcDList.
5691 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5692 and use TRQ internally).
5694 Also fixed some annoying warning messages that the original TRQ
5695 code generated. Also minor changes to TRQ's Makefile.in.
5697 * Added support for querying by Client ID to both WHOIS and
5698 IDENTIFY commands into server, as required by the protocol.
5700 * Removed method function pointers from SilcBuffer structure. They
5701 weren't used to anything and just increased the context size for
5702 no good reason. This change also made silc_buffer_alloc and
5703 silc_buffer_free functions inline functions.
5705 * Disabled command flooding detection support until it's fixed so
5706 that it accepts commands in but does not execute them more than once
5709 * Added silc_net_localhost(), to return local hostname, into
5710 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5711 that must be initialized before calling silc_client_init.
5713 * Added new function: silc_server_send_notify_on_channels to send
5714 notify messages to all channels client has joined. It is assured
5715 that the message is sent only once per client.
5717 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5718 lib/silcutil/silcutil.[ch] as silc_format function. The new
5719 function is generic and is used by server as well, not only by
5720 the logging routines.
5722 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5723 the provided version string was not acceptable. Added new function:
5724 silc_ske_check_version into lib/silcske/silcske.h. The function
5725 must be implemented by the application (client or server) and it
5726 does not reside in the SKE library. The function checks the version
5727 string remote end sent.
5729 * Added back pointers (to opaque context and to SilcSocketConnection)
5730 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5732 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5733 duplicate packet context structure.
5735 * Changed `notify' client operation to send same arguments as client
5736 receives from server except for ID's. ID's are mapped to correct
5737 ID entry and that is returned. Also, if channel entry is not sent
5738 by server but the notify is for channel the channel entry is sent
5739 to application (otherwise application doesn't know that it is for
5740 channel (library gets it from packet's Destination ID)).
5742 * Added silc_client_remove_from_channels into client library to
5743 remove a client from all channels it has joined to. Used when
5744 received SIGNOFF notify from server. Added also new function
5745 silc_client_replace_from_channels to replace old ID entry with
5746 new ID entry on all channels. Used when received NICK_CHANGE
5749 * Fixed ID Cache list handling in silc_idlist_get_client in
5750 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5751 to get (or query) client by ID.
5753 * Updated TODO list.
5755 * Added connection authentication status message defined by the
5756 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5757 support for these into the code in client and server side.
5759 * Added generic function silc_client_send_command to send any command
5760 with variable argument list. Application should use this function
5761 to send commands if the command functions provided by the library
5762 does not suite for the application's user interface needs.
5764 * Added new `failure' client operation. Application is notified about
5765 received failure packet if client is executing a protocol. In this
5766 case the protocol's execution has failed.
5768 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5769 is required by the protocol.
5771 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5772 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5775 * Added status flag to SilcSKE object to indicate realtime status
5776 of the SKE protocol.
5778 * Application receives now exactly same command reply arguments as
5779 the library receives from server. However, if ID is received the
5780 corresponding ID entry is returned to the application (eg. Client
5781 ID is mapped to correct SilcClientEntry entry and that is returned).
5782 Changed command_reply client operation due to this change.
5784 * Changed all ID's in commands and in command replys as ID Payloads.
5785 Change affected both client and server side codes.
5787 All ID's sent in SILC network (with execption of ID's in SILC
5788 Packet header) are sent in ID Payload to support variable length
5791 * Server now notifies nick changes and notifies all clients on
5792 the channels about the new nickname (about the new Client ID,
5795 * Implemented CMODE command to change channel modes. Supports all
5796 channel modes defined by the protocol specs except ban and invite
5797 lists. (Also, private channel key mode is supported but support for
5798 setting private channel key in client is missing, thus, this mode
5799 has no effect on client side (except that server requires that the
5800 client uses private channel key and normal channel traffic does not
5803 Also, invite mode works per se, but INVITE command does not work
5804 yet correctly, so you can set channel as invite only channel but
5805 inviting clients to the channel does not work (it is yet to be
5806 thought what's the best way to do it).
5808 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5809 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5810 Implemented CUMODE command to change user's mode on the channel.
5811 Supports all modes defined by the protocol specs.
5813 * Added NAMES command reply to return users modes on the channel.
5815 * Removed unnecessary and slow ciphers from lib/silccrypt.
5817 * Set SO_KEEPALIVE option to connection sockets by default.
5819 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5821 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5822 redefined the Notify Payload into protocol specs.
5824 * Added silc_id_payload_parse_id to get ID directly from raw
5827 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5830 accept searching by Client ID as well.
5832 * Added support for LEAVE and SIGNOFF notify types in client library.
5834 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5835 to parse ID Payload from raw data.
5837 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Added flags parameter into silc_ske_assemble_security_properties
5840 function in lib/silcske/silcske.[ch].
5842 * Changed notify client operation to fit better for notify messages
5843 sent by server. The notify payload received from server is now
5844 passed to the application (after parsing it to SilcNotifyPayload).
5845 It is application's responsibility to retrieve the arguments
5846 from the payload and show the message the way it wants. The message
5847 sent by server is implementation specific.
5849 * Changed public keys to comply with the protocol specification.
5850 Old public keys are not supported anymore and are not compatible.
5852 * Removed nickname from Channel Payload as the latest draft removed
5853 it. The client must resolve the nickname from the NAMES command
5854 reply received when it joined the channel.
5856 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5858 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Fixed some errors in protocol specification drafts.
5862 * Created lib/silccore/silcnotify.c to implement Notify Payload
5863 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5864 generic payloads described by protocol specifications. The file
5865 includes implementations for ID Payload and Argument Payload.
5867 * Changed Command Payload implementation to use the new Argument
5868 Payload. Changed command_xxxx_payload to command_payload_xxxx
5869 to comply with SILC coding conventions.
5871 * Added suppport for Argument Payload handling in Notify Payload
5872 implementation as protocol requires it. Added the new support
5873 into server and client lib as well.
5875 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5877 * Added support for multiple nicknames on same channel. [n] is
5878 added locally to the nickname if there are more than one same
5879 nicknames on the channel.
5881 * Server now sends all nicknames that matched WHOIS request.
5882 Client also shows the list received from server.
5884 * Added TOPIC command to client side. User can now set and show
5885 current topic on channel.
5887 * Added MOTD command to client and server. Also, server sends the
5888 motd when client connects to the server.
5890 * Changed version strings to comply ISO 8601.
5892 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5894 * Fixed protocol error handling in client library. It should now
5895 cope even if the SKE fails for some reason.
5897 * Made new protocol specification drafts for submitting to IETF.
5899 * Implemented TOPIC command to server in silcd/command.c.
5901 * Added two new notify types into lib/silccore/silcnotify.h:
5902 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5903 notify nickname change and topic setting/change on a channel.
5905 * API change of command_reply operation in client library. The
5906 application gets now the status type received from server as well.
5908 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5910 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5912 * Cras fixed and optimized the packet handling even further and
5913 it should work now. Minor change to the prototype of function
5914 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5916 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added new function into lib/silcutil/silcschedule.[ch]:
5919 silc_schedule_with_fd to select() a specified fd. The function
5920 returns after timeout expires or data arrives or goes. The
5921 function is used by packet routines to wait that all data is
5922 received from network.
5924 * Fixed data reading from network in lib/silccore/silcpacket.c.
5925 The code now assures that all data is read from the fd and then
5926 continues packet processing. This was a bug fix since the code
5927 used to drop some data in some circumstances.
5929 * Added new function into lib/silcclient/client.[ch]:
5930 silc_client_start_key_exchange to start key exchange after
5931 connection has been established to server. The code internally
5932 now uses this funtion but its main purpose was to provide it
5933 for applications that perform their own connecting. After
5934 application has created a connection it merely calls this
5935 function to start the key exchange between client and server.
5936 The library takes care of everything else after that.
5938 Updated also lib/silcclient/README to explain the usage of
5941 * Do not send to application information that connection has
5942 been established. Application gets notified it by connect
5945 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Applied cras's patch to add silc_schedule_one function. The
5948 function runs scheduler once and returns.
5950 * Fixed the scheduler after cras messed it up. The timeout
5951 handling works now as it's supposed to work.
5953 * Added into lib/silccore/ silcnotify.h to include notify
5954 message types support. Changed silc_server_send_notify*
5955 functions, in server.[ch], to support those new notify types.
5956 Added the support for the notify types into client library,
5957 as well. Added new notify client operation into ops.h in
5960 * Changed silc_server_packet_send_to_channel to send normal
5961 packets instead of just channel message packets. The function
5962 is now used to send the notify packets to channels. It is not
5963 used to send channel message packets anymore, as server never
5966 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5967 va_arg()s as it seems to require it nowadays. I guess, if SILC
5968 is compiled with older va_arg() the new code should work anyway.
5970 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Splitted core library. Core library (lib/silccore) includes
5973 now only SILC protocol specific core (and common) components.
5974 Created new utility library (lib/silcutil) that includes more
5975 generic purpose stuff. The stuff for util library was taken
5976 from the old core library. This was minor and easy split.
5978 * Created SILC Client Library (lib/silcclient) that includes
5979 implementation of the SILC client without user interface. This
5980 was major move from silc/ directory. The code has been changed
5981 so that it is transparent towards the user interface. The
5982 silc/ directory includes now the same user interface as before
5983 and it uses the new client library. Read lib/silcclient/README.
5984 Basicly, the client library performs everything else related
5985 to SILC except user interface handling. Also, configuration
5986 files are considered to be part of user interface and library
5987 does not handle them.
5989 This change also changed a lot of structures, function naming etc.
5990 Most important change was that SilcClientWindow object was
5991 renamed to SilcClientConnection in the client library. Created
5992 also new file lib/silcclient/ops.h. Also added new files
5993 silc/local_command.[ch] and silc/client_ops.[ch].
5995 All these changes were made to make it easier for user interface
5996 designers to create what ever user interface for the SILC client
5999 It is also expected that the server will be moved to lib
6000 directory as well and SILC Server Library will be created;
6001 sometimes in the future.
6003 * Removed Local commands from lib/silccore/silccommand.h as
6004 they are application specific and new client library does not
6005 handle any of those anymore.
6007 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6008 old client implementation in silc/.
6010 * Added support for callback functions in SILC_LOG_* macros.
6011 Application can now set its own callbacks that will be called
6012 instead of using the default functions that will always print
6013 the debug messages to stderr (or stdout). Also, debugging can
6014 now be disabled by setting silc_debug to FALSE and re-enabled by
6015 setting it to TRUE. Note, that logging will still work even
6016 if debugging is disabled.
6018 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6019 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6020 silc_log_reset_debug_callbacks.
6022 * To enable debugging in silc client one must give now -d
6023 option on command line.
6025 * Changed silc_schedule_init to automatically allocate task queues
6026 if they are not allocated before calling it.
6028 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Added GMP 3.1 into math library.
6032 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
6035 a channel in SILC network. The packet is used by servers and
6036 routers to notify other routers that user has left a channel.
6037 This little feature was missing until now. Added the feature
6038 to protocol specification as well.
6040 Added functions: silc_server_send_remove_channel_user and
6041 silc_server_remove_channel_user into server.[ch].
6043 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
6044 lib/silccore/silcpacket.h. However, they are not implemented
6047 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * Fixed joining to a channel and sending channel messages
6050 between server and router. The channel message sending should
6051 now work inside a cell.
6053 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Fixed the private message sending between server and router.
6056 The private message sending should now work inside a cell.
6058 * Added silc_server_replace_id into server.[ch] to replace
6059 existing ID in the SILC network.
6061 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
6062 and silc_idlist_replace_server_id into idlist.[ch] in server.
6064 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * Fixed the server to server connections. Server can again now
6067 connect to router. Router to router connections probably does
6070 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6072 * Added dynamic protocol registering support. Now protocols can
6073 registered and unregistered on the fly. Patch by cras.
6075 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Added lib/contrib directory to hold routines that some platforms
6078 don't have but are needed by SILC.
6080 * Added getopt.c, getopt1.c and getopt.h from GNU C library
6081 into lin/contrib to provide getopt() and getopt_long() for
6082 those who don't have it.
6084 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Added AWAY command to client. When away message is set and
6087 client receives a private message packet the client automatically
6088 replies to the sender with the away message.
6090 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
6091 bug seemed to be the cause of recent problems when compiling
6094 * Added version detection support to SKE protocol specification
6095 and added the new changes to the SKE implementation as well.
6096 There were other minor changes in the SKE protocol as well.
6098 Many changes in lib/silcske/silcske.[ch] and in
6099 lib/silcske/payload.[ch].
6101 * Added ^U functionality, clear input line. Patch from cras.
6103 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * Mainly small bugfixes on core library. Fixed some debugging
6106 logging and buffer overflow in silclog.c.
6108 * Updated config.sub and config.guess on the distribution tree.
6110 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Added command lagging support in server. Client may execute
6113 commands now only once in two seconds.
6115 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Optimized packet reception. MAC computation and checking is now
6118 also more optimized. A lot previously duplicated code is now
6119 used as generic by both client and server.
6121 * Fixed key pair generation in clientutil.c
6123 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6125 * Added into lib/silccore/silcbufutil.[ch] new function;
6126 silc_buffer_realloc.
6128 * Moved generic packet sending/encryption functions to
6129 lib/silccore/silcpacket.[ch] from client and server. Some
6130 rewriting of the functions.
6132 * Moved all generic packet reception/decryption functions to
6133 lib/silccore/silcpacket.[ch] from client and server. The
6134 packet processing is now much cleaner in both client and server.
6135 These were major changes in both client and server.
6137 * Created many common functions in server to do packet sending.
6138 Previously code were duplicated a lot, this has been removed
6141 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6143 * Rewrote major parts of the ID cache system. Don't know
6144 whether it is better now or not but at least the API is more
6147 * Major rewrite on ID cache stuff on client because of the ID
6148 cache API changes. Added idlist.c to client.
6150 * Also major rewrite on ID cache stuff on server as well.
6151 Major rewrite of idlist.[ch]. SilcXXXList's are now named
6152 SilcXXXEntry's. We won't keep anymore idlist specific pointers
6153 in hand, instead they are all put into the ID cache system now.
6154 All server_idlist_* routines uses ID cache now instead of
6155 traversing its own lists (those lists does not exist anymore).
6156 SilcIDList though still exists. Also, SilcXXXEntry's are
6159 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6161 * Finally made the SKE implementation compliant to the protocol
6162 specification. All mp integers are now binary encoded as
6163 opposed being HEX encoded.
6165 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
6168 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
6169 functions: silc_[encode/decode]_pem. Also added function
6170 silc_encode_pem_file to PEM encode with newlines ('\n') for
6173 * SILC public keys are now encoded either PEM or binary. Same
6174 option is for private keys as well. By default private keys
6175 are binary encoded and public keys PEM encoded. Silly HEX
6176 encoding were removed.
6178 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
6179 function to create fingerprints.
6181 * Fixed a bug in SHA1; does not change the original data anymore.
6183 * Partly implemented INFO command on client and server side.
6184 Fixed CLEAR command. Changes to SERVER command; show current
6185 server(s) when giving command without arguments. Added
6186 VERSION command to client.
6188 * Added check to server that unregistered connections cannot
6189 execute commands (unless it is specificly allowed).
6191 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Fixed screen refresh.
6195 * Fixed channel joining bug from client. On some circumstances
6196 client tried to join to a channel it had already joined.
6198 * Added public key verification process into client's protocol.c.
6199 The client now verifies the public key from user and saves
6200 it into ~./silc/serverkeys/ directory.
6202 Added into: clientutil.[ch]: silc_client_verify_server_key.
6204 * Changed SKE protocol's silc_ske_initiator_finish function
6205 to accept callback function that verifies the received public
6206 key. Removed old silc_ske_verify_public_key function.
6208 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
6211 silc_pkcs_private_key[_data]_set.
6213 * Made the password and public authentication more cleaner in
6214 server's protocol.c.
6216 * Removed historic and obsolete protocol `channel_auth' from
6217 both client and server.
6219 * Removed wrong way of sending command status messages from
6220 server to client in server's command.c. The old way violated
6221 protocol specification.
6223 Changes to silccore/silccommand.[ch]: removed
6224 silc_command_encode_status_payload -> not needed anymore,
6225 changed silc_command_encode_payload_va to accept extra
6226 argument on variable argument list. The argument type must
6227 now be provided to the function. Also, added new function:
6228 silc_command_encode_reply_payload_va which is same as
6229 normal command_encode_payload_va except command status type
6230 is provided as extra argument.
6232 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * Added ~./silc directory handling. The directory includes the
6235 public and private keys for the client.
6237 Added silc_client_check_silc_dir, silc_client_create_identifier
6238 and silc_client_load_keys.
6240 * Implemented SILC protocol compliant public key. Added public
6241 and private key saving to and loading from files.
6243 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
6244 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
6245 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
6246 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
6247 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
6249 Implemented: silc_pkcs_save_[public/private]_key[_data] and
6250 silc_pkcs_load_[public/private]_key.
6252 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Added silc_server_get_route (route.[ch]) to get connection
6255 data for the fastest route for given ID.
6257 * Implemented INVITE command on client and server. The command
6258 were re-defined in the SILC Protocol Specification and the
6259 implementation now complies with the specification.
6261 * Implemented PING command on client and server.
6263 * Implemented NAMES command on client and server. The server side
6264 supports currently only normal server not router server yet.
6265 Some changes to NAMES definition in SILC protocol specification.
6267 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6269 * Implemented LEAVE command on client and server.
6271 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
6272 again. This change was made to the protocol as well. Server
6273 should not violate the protocol specification anymore.
6275 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
6278 was tested. SOCKS4 was not but should work anyway.
