1 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added silc_pkcs_public_key_compare to compare two
4 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
6 * Check that the client who set the founder mode on the
7 channel is the same client that is giving the founder
8 mode to itself. It is done by comparing the saved public
9 key (it is saved even in the authentication is passphrase).
10 Affected file silcd/command.c.
12 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
14 * Do not process packet for disconnected socket connection.
15 Affected file lib/silccore/silcpacket.c.
17 * Process the DISCONNECT packet through scheduler in the
18 client library. Affected file lib/silcclient/client.c.
20 * Fixed the silc_client_packet_parse to not to increase
21 the packet sequence number if the conn->sock and the
22 current socket connection is not same. This can happen
23 for example during key agreement when the conn includes
24 multiple socket connections (listeners). Affected file
25 lib/silcclient/client.c.
27 * The sender of the file transfer request now provides also
28 the pointer (listener) for the key exchange protocol. If
29 the listener cannot be created then it sends empty key
30 agreement and lets the receiver provide the listener.
32 Added `local_ip' and `local_port' arguments to the
33 silc_client_file_send. If they are provided they are used,
34 if not then it will attempt to find local IP address, if
35 not found or bind fails then the remote client will provide
38 Affected files are lib/silcclient/client_ftp.c and
39 lib/silcclient/silcapi.h.
41 * Extended the FILE SEND command to support defining the
42 local IP and port for key exchange listener. They are

47 * Defined to WHOIS command reply the sending of fingerprint
48 of the client's public key (if the proof of posession of the
49 corresponding private key is verified by the server).
50 Updated to the protocol specification.
52 * Added support of receiving the client's public key's
53 fingerprint in command reply in client library. Affected
54 file is lib/silcclient/command_reply.c, and
55 lib/silcclient/idlist.[ch].
57 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

113 during SERVER_SIGNOFF, but invalidate it. This way we
114 preserve the WHOWAS info for the client. Affected file
117 * Fixed SERVER_SIGNOFF notify handling in the server. The
118 server is now able to process incoming SERVER_SIGNOFF notify
119 for a server that it doesn't even know about. It will remove
120 the clients provided in the notify. Affected file
121 silcd/packet_receive.c.
123 * Check for partial packet in data queue after every packet that
124 was found from the queue. Return and wait for more data if
125 there is partial data in queue. Affected file is

150 available. It is used in padding generation. Affected file
151 lib/silccrypt/silcrng.[ch].
153 * All packets in client library are now processed synchronously.
154 Optimized packet processing a lot. Affected file
155 lib/silcclient/client.c.
157 * All server connection packets are processing synchronously
158 now in server, to optimize packet processing. Affected file
161 * Include files are installed now only in Toolkit distribution
162 if make install is given. Affected files: all Makefile.am's.
164 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
166 * Assure that silc_client_notify_by_server_resolve does not
167 resolve the client information multiple times. If it cannot
168 be found by the first it cannot be found at all. Affected
169 file lib/silcclient/client_notify.c.
171 * Fixed WHOWAS command reply calling. Affected file
172 lib/silcclient/command_reply.c.
174 * Removed all references to silc_idlist_get_client from the
175 Irssi SILC client since that call is internal call used by
176 the library. The Irssi SILC client will use now client
177 retrieval functions found in silcapi.h.
179 * Fixed a bug in resolving nickname info before sending
180 private message. It used freed memory. Affected file
181 irssi/src/silc/core/silc-servers.c.
183 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

202 * Added silc_net_localip to return local host's IP address.
203 Affected file lib/silcutil/silcnet.[ch].
205 * If key exchange or rekey protocol is active for a connection
206 parse all packets syncronously since there might be packets
207 in packet queue that we are not able to process without first
208 processing packets before them. Affected file silcd/server,
209 lib/silcclient/client.c.
211 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
212 whether library should continue processing the packet.
213 Affected file lib/silccore/silcpacket.h.

246 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
248 * Resolve the client info when received private message or
249 channel message for a client which nickname we don't know.
250 Affected files lib/silcclient/client_prvmsg.c and
251 lib/silcclient/client_channel.c.
253 * Do not crash in /KEY if client is not connected. Affected
254 file irssi/src/silc/core/silc-channels.c.
256 * Added SilcClientStatus field to the SilcClientEntry in the
257 lib/silcclient/idlist.h.
259 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
260 is incomplete and is being resolved, it won't be resolved
263 Make sure also that USERS command reply does not resolve
264 twice information. Affected file is
265 lib/silcclient/command_reply.c.
267 Make sure that silc_client_get_clients_by_list does not
268 resolve twice same information.
270 * Check for valid client->id in the silc_server_free_client_data.

286 * Call the silc_server_udpate_servers_by_server in the
287 primary router that comes back online in the backup resuming
288 protocol. Otherwise it routes packets wrong. Affected file
289 silcd/server_util.[ch], silcd/server_backup.c.
291 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
293 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
294 lib/silcutil/silcbuffmt.[ch].
296 * Redefined the SILC packet header to include the padding
297 length. Affected file lib/silccore/silcpacket.[ch].
299 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
300 length for maximum padding up to 128 bytes). Affected
301 file lib/silccore/silcpacket.h.
303 * Removed all backwards support for old 0.5.x MAC thingies.
304 The SILC packet header change makes it impossible to be
305 backwards compatible.
307 * Send the ENDING packet with timeout in the backup resuming
308 protocol. This is to assure that all routers has connected
309 to the primary router. Affected file silcd/server_backup.c.
311 * Changed the RNG to take the first IV from random data. It
312 used to take it from zero actually. Changed the RNG also
313 to use /dev/urandom during session. /dev/random is used
314 in initialization. Affected file lib/silccrypt/silcrng.[ch].
316 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
318 * Changed the SILC packet header to have the first two bytes
319 (the packet length) encrypted. Affected files aroung the
320 code tree, lib/silccore/silcpacket.[ch]. Removed the
321 SilcPacketCheckDecrypt callback. It is not needed anymore
322 since the silc_packet_receive_process will determine now
323 whether the packet is normal or special.
325 * Implemented the unidirectional MAC keys. Affected files
326 lib/silcske/silcske.c, silcd/protocol.c and
327 lib/silcclient/protocol.c.
329 * Implemented the packet sequence number to the MAC computation.
330 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
331 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
332 lib/silcclient/protocol.c.
334 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
336 * Allow backup router to announce servers. All servers
337 announced by backup router are added to the global list
338 automatically. Update hte server's socket to our primary
339 router also when backup router announces a server.
340 Affected file silcd/packet_receive.c.
342 * Do not update the client->router in the function
343 silc_server_udpate_clients_by_server if the client is on
344 global list. We might fail to find any specific server
345 for locally connected clients and local cell clients. They
346 should still use the `from' and not `to' as client->router.
347 This fixes backup router resuming protocol. Affected file
350 * Decrease channel statistics count only if the channel
351 deletion worked. Affected files are silcd/server.c and
354 * Added silc_server_update_servers_by_server to update origin
355 of all server entries. Used during backup router protocol.
356 Affected files silcd/server_util.[ch], silcd/server.c. and
357 silcd/backup_router.c.
359 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
360 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
361 silc_hmac_get_hash and silc_hmac_get_name. Affected file
362 lib/silccrypt/silchmac.c.
364 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Assure that router cannot reroute the same channel message
367 to the sender. Affected file silcd/packet_receive.c.
369 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Made better checks that the channel message is not sent
372 to the router it came from. Affected file is
373 silcd/packet_send.c. Fixed memory leak too.
375 * Announce informations for incoming router connection, but
376 only after checking if it is replaced by backup router.
377 Affected file silcd/packet_receive.c.
379 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
381 * Fixed the backup resuming protocol to work in multiple
382 router environment. Affected file silcd/server_backup.c.
384 * Route packet only to one router in the function
385 silc_server_packet_send_to_channel. Affected file is
388 * Fixed silc_server_send_notify_dest to set the broadcast
389 flag. Fixed the silc_server_send_notify_topic to actually
390 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
391 Affected file silcd/packet_send.c.
393 * Changed the SFTP Filesystem interface. Changed the
394 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
395 the filesystem operation function. The SilcSFTPFilesystem
396 is now a context that is allocated by all filesystem allocation
397 functions and it already includes the operations structure
398 and filesystem specific context. It is given as argument
399 now to the silc_sftp_server_start. This made the interface
400 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
401 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
403 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
405 * Changed the backup router adding and getting interfaces
406 in the server. The router that will be replaced by the
407 specified backup router is now sent as argument. Affected
408 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
411 * Added silc_net_addr2bin_ne to return the binary form of
412 the IP address in network byte order. Affected files
413 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
415 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
417 * Check for existing server ID in silc_server_new_server
418 and in silc_server_connect_to_router_final and remove the
419 old entry if it exists. Affected file silcd/packet_receive.c,
422 * Send the channel message always to only one router, either
423 in upstream or downstream. Affected file is
426 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Wrote the definition of the backup resuming protocol to the
429 protocol specification.
431 * Removed one redundant channel key generation from normal
432 server during joining procedure. Removed one redundant
433 channel key sending from server to router during joining
434 procedure. Affected file silcd/command.c.
436 * Made minor bugfixes to the backup router resuming protocol.
437 Affected file silcd/server_backup.c, server.c.
439 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
441 * Added --disable-asm configuration option. Affected files
442 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
445 * Implemented the backup resuming protocol that is used to
446 resume the primary router position in the cell after the
447 primary router comes back online. Affected files
448 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
449 and silcd/server_util.[ch].
451 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
453 * Sleep two (2) seconds after sending QUIT command to server.
454 Affected file lib/silcclient/command.c.
456 * Assure that if outgoing data buffer is pending do not force
457 send any data. Affected file silcd/packet_send.c.
459 * Assure that if outgoing data buffer is pending do not force
460 send any data. Affected file lib/silcclient/client.c.
462 * Implemented the backup router support when the primary router
463 goes down. The servers and routers can now use the backup
464 router as new primary router without loosing connectivity.
466 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
468 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
469 in the server to indicate disabled entry. All data read
470 from the connection will be ignored and no data is sent
471 for entry that is disabled. Affected files are
472 silcd/idlist.h, silcd/server.c.
474 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
476 * Created SFTP client and server test programs in the
477 lib/silcsftp/tests directory.
479 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
481 * Implemented memory filesystem (virtual filesystem) for
482 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
485 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
487 * Implemented the SFTP (SSH File Transfer Protocol) to the
488 lib/silcsftp. It includes SFTP client and SFTP server
491 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Moved lib/silccore/silcprotocol.[ch] to the
494 lib/silcutil library.
496 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
497 take variable argument list pointer as argument. Affected
498 file lib/silcutil/silcbuffmt.[ch].
500 * Added silc_buffer_set function that is used to set data
501 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
502 Affected file lib/silcutil/silcbuffer.h.
504 * Changed various routines in the core library to use the new
505 silc_buffer_set instead of allocating new buffer only for
508 * Added 64-bit value formatting and unformatting support to the
509 silc_buffer_[un]format routines. Affected file is
510 lib/silcutil/silcbuffmt.[ch].
512 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
513 to includes/bitmove.h.
515 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Fixed channel user mode saving in client library. Affected
518 file lib/silcclient/command[_reply].c.
520 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
522 * Defined the file transfer to the SILC Protocol. Added
523 new packet type SILC_PACKET_FTP and defined File Transfer
524 Payload. The mandatory file transfer protocol is SFTP
525 (SSH File Transfer Protocol). Affected file in addition
526 of the internet draft is lib/silccore/silcpacket.h.
528 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
529 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
530 is used as part of backup router protocol when the primary
531 router of the cell is back online and wishes to resume
532 the position as primary router.
534 * Redefined the MAC generation keys in the protocol. The
535 same key is not used anymore in both direction. Both
536 direction will now use different keys for sending and
537 receiving. This fixes a potential security flaw. This
538 change causes incompatibilities in the protocol.
540 * Redefined also the MAC computation from the packet.
541 An packet sequence number is now added to the MAC
542 computation. This prevents possible replay attacks against
543 the protocol. This change too causes incompatibilities
546 Added `sequence' field to the SilcPacketContext to hold
547 the current sequence number for the packet.
549 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
551 * Added `created' field to the SilcIDListData in the file
552 silcd/idlist.h to indicate the time when the entry was
555 * Added `created' field to the SilcChannelEntry too. Affected
558 * Added `creation_time' aguments to all the announcement functions
559 in the server. If it is provided then only the entries that
560 was created after the provided time frame are actually
561 announced. Affected file silcd/server.[ch].
563 * The protocol says that the Channel ID's IP address must be
564 based on the router's IP address. Added check for this in
565 the silc_server_new_channel when processing incoming New Channel
566 Payload. Affected file silcd/packet_receive.c.
568 * Print out the correct version with --version in SILC client.
569 Affected file irssi/src/silc/core/silc-core.c.
571 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
573 * Fixed WHOWAS command to check for completnes of the client
574 entry always, not just when the command is coming from client.
575 Affected file silcd/command.c.
577 * Added new function silc_server_packet_queue_purge to purge the
578 outgoing data queue to the network. After the function returns
579 it is guaranteed that the outgoing packet queue is empty.
580 Affected file silcd/packet_send.[ch].
582 * Purge the outgoing packet queue in the rekey protocol's final
583 callback to assure that all rekey packets go to the network
584 before quitting the protocol. Affected file silcd/server.c.
586 * Added silc_client_packet_queue_parse as similar function as
587 in server to the client library. The affected file is
588 lib/silcclient/client.c.
590 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
592 * Splitted silcd/server.c and created silcd/server_util.[ch]
593 for utility functions.
595 * Added new socket flag SILC_SF_DISABLED to indicate that the
596 connection is open but nothing can be sent to or received from
597 the connection. Affected file lib/silcutil/silsockconn.[ch].
598 The checking for disabled socket is checked in the low level
599 silc_socket_write and silc_socket_read functions.
601 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Allow only nicknames and channel names that fits into the
604 7-bit unsigned char ASCII set. Affected file silcd/command.c.
606 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
608 * When processing JOIN command reply in server check that if
609 the channel exists in our global list we'll move it the local
610 list. Affected file silcd/command_reply.c.
612 * Fixed the check whether client is joined on the channel already
613 in JOIN command. Affected file lib/silcclient/command.c.
615 * Fixed the JOIN command reply to check whether the channel
616 already exists. Affected file lib/silcclient/command_reply.c.
618 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Added silc_ske_status_string to map the SKE error numbers
621 to readable strings. The affected files are
622 lib/silcske/silcske[_status].[ch].
624 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
626 * Do not show the private channels on the WHOIS channel list
627 as it is not allowed by the protocol. The affected file is
630 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
632 * Assure that the packet length digged from the actual packet
633 is something sensible in the silc_packet_decrypt_rest_special
634 in lib/silccrypt/silcpacket.c.
636 * Free and NULL the allocated pointer in silc_hmac_alloc if
637 the HMAC allocation fails. The affected file is
638 lib/silccrypt/silchmac.c.
640 * Print the selected security properties to the log files in
641 the server. Affected file silcd/protocol.c.
643 * Add SKE's reference counter even if calling the completion
644 callback manually. Otherwise it goes negative, although it
645 does not cause any problems. The affected file is
646 lib/silcske/silcske.c.
648 * Remove the client entry with short timeout after giving the
649 KILL command. Affected file lib/silcclient/command.c.
651 * Fixed to send error reply in WHOIS and IDENTIFY commands in
652 case all found clients are already disconnected (WHOWAS would
653 found them) in the server. Affected file silcd/command.c.
655 * Update the last_receive (time of last data received) to be
656 updated only when received private or channel message so that
657 the idle time showed in WHOIS makes more sense.
659 * Added boolean field `valid' in to the SilcClientEntry in the
660 client library to indicate whether the entry is valid or not.
661 This fixes the nickname change bug on channel when changing
662 the nickname to be same than the old (like nick to Nick) the
663 nickname formatter doesn't set the new nick anymore to Nick@host.
664 Affected file lib/silcclient/idlist.[ch].
666 * Now actually fixed the nickname changing on disconnection.
667 Added new function silc_change_nick to the Irssi SILC Client.
668 Affected file irssi/src/silc/core/client_ops.c,
669 irssi/src/silc/core/silc-nicklist.[ch].
671 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
673 * Check that the public key exists in the GETKEY command before
674 trying to encode it. Affected file silcd/command.c.
676 * Print some notifications on received public keys with GETKEY
677 command in the Irssi SILC Client. Affected files are
678 irssi/src/fe-common/silc/module-formats.[ch],
679 irssi/src/silc/core/client_ops.c.
681 * Use IDENTIFY command to resolve the server information in the
682 GETKEY command instead of INFO command. Affected file
683 lib/silcclient/command.c.
685 * All command reply functions in the client library now calls
686 the pending command reply callbacks even if an error has
687 occurred. The server has done this a long time and now it was
688 time to move the client library to this as well. Now all
689 errors can be delivered back to the pending command reply
690 callbacks if necessary. Affected files are
691 lib/silcclient/command[_reply].[ch].
693 * Change the nickname on disconnection back to the username
694 because in reconnect the server will enforce it to it anyway.
695 Affected file irssi/src/silc/core/silc-servers.c.
697 * Fixed a config file parsing bug in the Irssi SILC client.
698 Affected file irssi/src/silc/core/clientconfig.c.
700 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
702 * When printing the channel mode on JOIN, verify that the
703 channel key and channel's HMAC are valid. Affected file
704 irssi/src/silc/core/client_ops.c.
706 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
708 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
709 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
710 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
712 * Removed channel key rekey task deleting from the function
713 silc_server_save_channel_key. Affected file silcd/server.c.
714 Added explicit timeout task context instead that is used to
715 delete the task if we are registering a new task before the
716 new task has elapsed.
718 * When channel key rekey occurs the client library now saves
719 the old channel key for a short period of time (10 seconds) and
720 is able to use it in case some is still sending channel
721 messages encrypted with the old key after the rekey. Affected
722 file lib/silcclient/[idlist.h|client_channel.c].
724 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Added check to the silc_server_new_id_real to not accept
727 new ID if it is the sender's own ID. Affected file is
728 silcd/packet_receive.c.
730 * Assure that we do not announce ourself or the one we've
731 sending our announcements when we're router and are announcing
732 servers to our primary router. Affected file silcd/server.c.
734 * Fixed silc_server_command_identify_check_client to assemble
735 correct WHOIS packet. It send corrupted WHOIS packet and
736 caused problem with router to router connections. Affected
737 file silcd/command.c.
739 Fixed also silc_server_command_whois_check the same way
740 as for the IDENTIFY command.
742 * Added new SilcIDListStatus to the server in the SilcIDListData
743 structure. The status now includes the current status of
744 the entry (like registered, resolved etc.). Affected file
745 silcd/idlist.[ch]. Defined a bunch of different status types
746 as well. This replaced the old boolean registered field as well.
748 Added resolve_cmd_ident field to the SilcClientEntry structure
749 too so that if the entry is for example being resolved so
750 another command may attach to the same pending command reply
751 without requiring to resolve the same entry again. This concept
752 should optimize the WHOIS and the IDENTIFY resolving under
753 heavy load by taking away unnecessary resolving for entries
754 that are being resolved already.
756 Added support for adding multiple pending commands for one
757 command idenfier. Affected file silcd/command[_reply].[ch].
759 * Fixed WHOIS and IDENTIFY save to remove the cache entry
760 before deleting the data. Otherwise the hash table will have
761 freed data in comparison functions. Affected file is
762 silcd/command_reply.c.
764 * Fixed silc_idlist_replace_client_id to add the new entry to
765 the cache with NULL nickname. Otherwise there will be invalid
766 memory as the nickname after the nickname is freed. Affected
767 file silcd/packet_receive.c.
769 * Fixed the silc_idlist_get_clients_by_hash. The entries was
770 saved into wrong slots because the previous number of entries
771 was not taken into account. Affected file silcd/idlist.c.
772 Fixed same thing in silc_idlist_get_clients_by_nickname too.
774 * If we are router and we receive JOIN notify to a channel that
775 does not have any users then notified client is marked as the
776 channel founder, as it is it. The affected file is
777 silcd/packet_receive.c
779 * Added to the extended hash table API's table_del_*ext functions
780 the destructor as argument too, so that the caller can decide
781 which destructor to use or whether to use destructor at all.
782 Affected file lib/silcutil/silchashtable.[ch].
784 * Fixed ID Cache purging. It actually deleted the entries from
785 the hash table after the data was freed. The hash table ended
786 up comparing freed memory. The affected file is
787 lib/silccore/silcidcache.c.
789 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
791 * Fixed Irssi SILC client's KILL command's HELP syntax.
793 * The USERS command now resolves the detailed user information
794 if the userinfo field is missing. Affected file is
795 lib/silcclient/command_reply.c.
797 * Do not print error in silc_file_read if the read file does
798 not exist. Just silently return NULL. Affected file is
799 lib/silcutil/silcutil.c.
801 * Fixed the silc_log_output to not wine about NULL filename
802 and to not create some bogus " " filename. Affected file is
803 lib/silcutil/silclog.c.
805 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Fixed various printing bugs on the user interface in the
808 Irssi SILC Client. Minor changes that were forgotten from
811 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Fixed the configure.in.pre and the compilation and distribution
814 environment to support the new autoconf 2.52. That version is
815 now required to compile the CVS trunk.
817 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Renamed function silc_parse_nickname to silc_parse_userfqdn
820 to generally parse user@fqdn format strings. Affected file
821 lib/silcutil/silcutil.c.
823 * Added nickname_format and nickname_force_format fields to the
824 SilcClientParams structure. The first one defines the format
825 for the nicknames that the library will enforce if the receives
826 multiple same nicknames. The second one is boolean value and
827 can be used to force the library to always enforce the format
828 to the nicknames regardles whether there are multiple nicknames
829 or not. This configurable formatting was employed to flexibly
830 support accessing multiple nicknames from the user interface.
831 The userinterface can now set the nicknames to what ever format
832 they prefer. Affected file lib/silcclient/silcapi.h.
834 Added function silc_client_nickname_format to the file
835 lib/silcclient/idlist.c. It performs the nickname formatting.
837 Added new field `hostname´ to the SilcClientEntry context.
838 It holds the hostname of the client. Affected file is
839 lib/silcclient/idlist.h.
841 * Irssi SILC Client sets the nicknames in nick@hostn format.
842 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
843 irssi/src/silc/core/silc-core.c.
845 The WHOIS printing now also shows both the real nickname and
846 the formatted nickname so that user knows how to access the
847 user if there are multiple same nicknames cached. Affected
848 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
849 printing formatting too to take the hostname now as a separate
850 argument. The Affected file is
851 irssi/src/fe-common/silc/modules-formats.[ch].
853 * Changed the silc_client_get_clients_local to accept the formatted
854 nickname as argument. It accepts the real nickname too but the
855 formatted nickname can be used to find the true entry from
856 multiple entries. Affected file lib/silcclient/silcapi.h and
857 lib/silcclient/idlist.c.
859 * Added nickname_format_parse field to the SilcClientParams.
860 It is a callback function provided by the application to parse
861 the nickname out of the formatted nickname string. The library
862 calls it to get the nickname from the formatted string. Since
863 the application generally knows better the format of the nickname
864 string it parses it instead of the library, even though library
865 encodes the formatted string. If the callback function is not
866 provided then the library will use the string as is. The
867 affected file is lib/silcclient/silcapi.h.
869 * All the nickname strings passed to the client library in
870 commands are now expected to be formatted nickname strings.
871 If the command does not support the formatted nickname string
872 it will assume that the sent string is the actual nickname.
873 Affected file lib/silcclient/command.c.
875 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
877 * Added public key authentication support to OPER and SILCOPER
878 commands in the client library. Affected file is
879 lib/silcclient/command.c.
881 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
883 * Changed the get_auth_methdod client operation to be asynchronous.
884 It can be async if the application resolves the authentication
885 method from the server during the negotiation. Added new
886 SilcGetAuthMeth completion callback that the application will
887 call after resolving the authentication method.
889 Added function silc_client_request_authentication_method that
890 the application can use to resolve the authentication method
891 from the server. Added also SilcConnectionAuthRequest callback
892 that the library will call after the server has replied. The
893 application can call this function if it does not know the
894 current authentication method.
896 Affected files are lib/silcclient/client.c and
897 lib/silcclient/silcapi.h.
899 * The Irssi SILC client now automatically resolves the authentication
900 method incase any configuration information is not present (and
901 currently there never is). The affected file is
902 irssi/src/silc/core/client_ops.c.
904 * Fixed public key authentication from the client library.
905 Affected file lib/silcclient/protocol.c. Changed also the
906 protocol specification about the public key authentication in
907 the connection authentication protocol. The actual data to be
908 signed is now computed with a hash function before signing.
910 * Fixed the public key authentication from the server as well.
911 Affected file silcd/protocol.c.
913 * Removed the mlock()'s from the memory allocation routines.
914 Affected file lib/silcutil/silcmemory.c. The ./configure does
915 not check anymore for the mlock(). Affected file is
918 * Fixed USERS command in server to allow the execution of the
919 command for private and secret channels if the client sending
920 the command is on the channel. Affected file silcd/command.c.
922 * Fixed silc_client_get_clients_local to return the clients
923 count correctly. It could return wrong value. Affected file
924 lib/silcclient/idlist.c.
926 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
928 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
929 types. The assembler optimizations seemed not to like 64-bit
930 data types. The assmebler optimizations thus are now enabled
931 also for BSD systems as opposed to only enable them for Linux.
933 * Do not check for threads at all on BSD systems. Affected
934 file configure.in.pre.
936 * Removed -n and -h options from the Irssi SILC Client since
937 they are not used in silc.
939 * Fixed the prime generation to assure that the first digit
940 of the generated random number is not zero since our conversion
941 routines does not like number strings that starts with zero
942 digit. If zero digit is seen the random number is regenerated.
943 This caused some corrupted RSA keys when the zero first digit
944 was met. Affected file lib/silcmath/silcprimegen.c.
946 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
948 * Fixed WIN32 configuration in the ./configure script.
949 Fixed to include xti.h on environments that has it.
950 Patches by Carsten Ilchmann and andrew.
952 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
954 * Changed the silc_id_create_client_id to be collision
955 resistant. It is now assured that there cannot be created
956 two same client ID's. I suspect that some weird bugs in
957 the server were actually caused by duplicate Client IDs.
958 Affected file silcd/serverid.[ch]. A router receiving
959 new ID now also assures and informs the sending server
960 if the ID caused collision.
962 * Changed the silc_id_create_channel_id to also assure that
963 there are no collisions.
965 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Statement about ignoring the Mutual Authentication flag when
968 performing rekey with PFS was a bit misleading. It is ignored
969 if it was set in the initial negotiation, it cannot be even
970 set in the rekey. Fixed in the ke-auth draft. Started the
971 new versions of the protocol drafts in the doc/.
973 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
975 * Fixed a bug in silc_client_command_identify_save when saving
976 new channel information. The channel name was no duplicated
977 and caused crash on exit. Affected file is
978 lib/silcclient/command_reply.c.
980 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
982 * Fixed the getkey command handling in the server. Send just
983 empty OK reply to the sender if the key could not be fetched
984 (but everything else was ok, like the key just was not available).
985 Changed the public key parameter to optional in the protocol
986 specs so that empty OK reply can be sent. Affected file
989 Added a message to Irssi SILC client to tell to user if the
990 server did not return a public key.
992 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Fixed a channel key regeneration bug. It registered new
995 timeout tasks exponentially until all system resources were
996 used. Affected file silcd/server.c.
998 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1000 * Added the SILC Document generator to the scripts/silcdoc.
1001 It can be used to generate the Toolkit Reference Manual out
1002 of the source tree. Internally it will also use the RoboDoc
1003 generator now imported in util/robodoc.
1005 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1007 * Added couple of return's in rekey protocol if error orccurred
1008 during the protocol. The execution must be terminated.
1009 Affected file silcd/protocol.c. Also, terminate the protocol
1010 always with timeout.
1012 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * The client's Client ID was created initally from the wrong
1015 nickname (it could have been in format nick@host) in the
1016 silc_server_new_client. Affected file silcd/packet_receive.c
1018 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * Added some SILC_LOG_ERROR's to various error conditions
1021 if client could not be added to ID cache. Affected files
1022 silcd/packet_receive.c and silcd/server.c.
1024 * When client's sock->user_data is freed, NULL also the
1025 client->router and client->connection pointers. Added check
1026 for these pointers being NULL to various places around the
1027 code. Affected file silcd/server.c.
1029 * Added client->data.registered == TRUE checks to various
1030 places around the code to assure that unregistered client's
1031 are not handled when it is not allowed. Affected file
1034 * Added `bool registered' fields to all
1035 silc_idlist_[server|client]_get_* routines to indicate whether
1036 the fetched client needs to be registered or not. Affected
1037 file silcd/idlist.[ch].
1039 * Add your own entry as registered to the ID cache in the
1040 server. Affected file server.c.
1042 * Fixed a bug in silc_server_new_server. The SilcServer was
1043 set as the new server's context instead of SilcServerEntry.
1044 This naturally caused some weird bugs.
1046 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1048 * Do not delete the channel rekey task when adding it
1049 for in silc_server_create_channel_key.
1051 * Changed the silc_server_create_channel_key to return
1052 TRUE or FALSE to indicate the success of the channel key
1055 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1057 * Fixed MSVC++ project files and added missing files to
1058 Makefiles under win32/.
1060 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Do not add TCP_NODELAY flag if the operating system
1063 does not have it defined. Affected files are
1064 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1066 * Fixed buffer overflow from Irssi SILC Client. Affected
1067 file irssi/src/fe-common/core/themes.c.
1069 * Fixed double free in client library in the file
1070 lib/silcclient/client.c when disconnecting from server.
1072 * Applied double free patch from cras to Irssi SILC client.
1073 Affected files irssi/src/core/[modules/expandos].c
1075 * Fixed the disconnection handling to Irssi SILC Client.
1076 The application must call silc_client_close_connection
1077 in ops->connect client operation in case of failure of
1078 the connection. Affected file is
1079 irssi/src/silc/core/client_ops.c.
1081 * Do not set sock->protocol to NULL in the function
1082 silc_client_close_connection after executing the protocol's
1083 final callback since the sock might not be valid anymore.
1084 Affected file lib/silcclient/client.c.
1086 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Do not enable SILC_THREADS if the linking with libpthread
1089 did not happen. Affected file configure.in.pre.
1091 * Added notion to protocol specification that server must
1092 verify the sent authentication payload with CMODE when
1093 setting the channel founder key. Implemented it to the
1094 server. Affected file silcd/command.c.
1096 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Added _EXTRA_DIST SILC distribution variable to the
1099 distributions file. It is used to conditionally add extra
1100 files or directories to the specific distribution. Affected
1101 files ./prepare, Makefile.am.pre and distributions.
1103 Removed the `_' from the start of the distribution names.
1106 * Added README.WIN32 for instructions to compile the Toolkit
1109 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1111 * Fixed a double free in disconnection in the server. Affected
1112 file is silcd/server.c.
1114 * Fixed the lib/silcske/groups.c to work now also with GMP
1115 MP library. The string conversion did not work when using
1116 specific base and the base is indicated in the string as well.
1118 * Created win32/ directory which now includes MSVC++ specific
1119 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1120 It will appear only in the toolkit distribution
1122 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1124 * Changed the key material distribution function in case when
1125 the hash output is too short. The data is now concatenated
1126 a bit differently than it used to. Made the change to the
1127 SKE protocol specification.
1129 * Added better GMP detection to configure.in.pre. A patch
1132 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Fixed a minor bug in SKE that might cause some problem on
1135 some platforms. Affected file lib/silcske/silcske.c.
1137 * Added the cookie checking for initiator in the SKE. It checks
1138 that the responder returns the sent cookie unmodified. The
1139 affected file is lib/silcske/silcske.c. Added new SKE
1140 error type INVALID_COOKIE that can be sent during the
1141 negotiation. Fixed some memory leaks as well.
1143 * Added the "invalid cookie" error message to Irssi SILC client's
1146 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Added `task_max' field to the SilcClientParams to indicate
1149 the maximum tasks the scheduler can handle. If set to zero,
1150 default values are used. Affected file lib/silcclient/silcapi.h.
1152 * Fixed memory leaks in silc_client_close_connection. Affected
1153 file lib/silcclient/client.c.
1155 * Added silc_client_del_client_entry to client library to free
1156 all memory of given client entry. Affected file is
1157 lib/silcclient/idlist.[ch].
1159 * Added new functions silc_client_del_channel and
1160 silc_client_del_server to delete channel and server entries.
1161 Affected file lib/silcclient/[silcapi.h/idlist.c].
1163 * Removed silc_client_del_client_by_id from silcapi.h.
1165 * Fixed the INFO command to return the server's own info
1166 correctly when querying by Server ID. Affected file is
1169 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1171 * Removed the non-blocking settings in WIN32 code in the
1172 silc_sock_[read/write] and added SleepEx instead. Affected
1173 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1174 of input data is now checked with FIONREAD and ioctlsocket.
1176 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Call silc_schedule_task_del_by_context in the
1179 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1180 Affected file lib/silccore/silcprotocol.c.
1182 * Call silc_protocol_cancel for active protocols in the
1183 silc_server_close_connection if the funtion
1184 silc_server_free_sock_user_data has not been called.
1185 Affected file silcd/server.c.
1187 * Generic tasks cannot be deleted using the del_by_fd
1188 task deleting function since generic tasks does not match
1189 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1191 * Added a notion to SILCOPER help file that the SILCOPER works
1192 only on router server, not on normal server.
1194 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1196 * Added for WIN32 support for the new scheduler as well.
1197 Affected file lib/silcutil/win32/silcwin32schedule.c.
1199 * Fixed the SHA1 implementation to work on various platforms.
1201 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1203 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1204 API. It is part of the scheduler now. Everything else is
1205 as previously but some functions has changed their names.
1206 Checkout the lib/silcutil/silcschedule.h for the interface.
1207 Updated all applications to use the new interface. Affected
1208 files are lib/silcutil/silcschedule.[ch].
1210 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Found a bug in the SKE implementation. The HASH value,
1213 specified by the protocol, was not computed correctly. The
1214 public key of the responder was not added to the computation
1215 even though it is mandatory. Affected file lib/silcske/silcske.c.
1216 This unfortunately causes incompatibilities with older
1217 clients and servers.
1219 * Added WIN32 specific network init and uninit functions:
1220 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1221 the Winsock2. Affected file lib/silcutil/silcnet.h and
1222 lib/silcutil/win32/silcwin32net.c.
1224 * Set the socket always to nonblocking mode on WIN32 after
1225 reading data or writing data. Affected file is
1226 lib/silcutil/win32/silcwin32sockconn.c.
1228 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1230 * Fixed various compilation problems under WIN32. Affected
1231 files lib/silcutil/win32/silcwin32thread.c and
1232 lib/silcutil/win32/silcwin32schedule.c.
1234 * Removed all _internal.h #includes from public header
1235 files. Internal headers must never be included from
1238 Removed also the lib/silcske/payload_internal.h file.
1240 * All include files that may be needed (public and some others
1241 included by the public headers) by application developers are
1242 now copied to the ./includes directory. It does not copy any
1243 internal headers. Affected file Makefile.defines.pre and all
1244 Makefile.am's under lib/ and subdirs.
1246 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1248 * Do not change the ~/.silc directory's permissions automatically.
1249 Affected file irssi/src/silc/core/clientutil.c.
1251 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Do not cancel the protocol in silc_server_close_connection
1254 it might cause recursion. Now cancelled in the function
1255 silc_server_free_sock_user_data. Affected file silcd/server.c.
1257 * Fixed the silc_server_remove_clients_by_server to regenerate
1258 the channel keys correctly finally. Added also new function
1259 silc_server_remove_clients_channels to actually do it.
1260 Affected file silcd/server.c.
1262 * Fixed the silc_server_new_channel to not crash by giving
1263 wrong router to the new channel. Affected file is
1264 silcd/packet_receive.c.
1266 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1268 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1269 which is given as argument to the silc_client_alloc now.
1270 It can be used to configure the client and set various parameters
1271 that affect the function of the client.
1273 * The USERS command in server did not check whether the channel
1274 is private or secret. Affected file silcd/command.c.
1276 * Added new argument to the USERS command in protocol specification.
1277 The USERS command now can take the channel name as argument
1278 as well. Added support for this in client and server and
1279 updated the protocol specs.
1281 * Completed the GETKEY command in client. It can be now used
1282 to fetch also servers public key not only some clients.
1283 Affected files lib/silcclient/command[_reply].c.
1285 * Added silc_client_get_server to return server entry by the
1286 server name. Affected files lib/silcclient/silcapi.h and
1289 * Redefined the IDENTIFY command in protocol specification to be
1290 more generic. It now can be used to query information about
1291 any entity in the SILC Network, including clients, servers and
1292 channels. The query may be based either the entity's name
1293 or the ID. Added support for this in both client and server.
1295 Affected files silcd/command.c and lib/silcclient/command.c
1296 and command_reply.c.
1298 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1299 the _from_client and _from_server functions. Affected file
1302 * Added silc_client_get_channel_by_id_resolve to the file
1303 lib/silcclient/silcapi.h to resolve channel information by
1304 its ID. Added also silc_client_get_channel_by_id that
1305 does not resolve it from the server.
1307 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Added SilcServerEntry context into the client library
1310 to represent one server. The INFO command now allocates
1311 these to save the resolved server info. For now on the
1312 client library will also keep information about servers,
1313 connected and resolved with INFO.
1315 The INFO command now allocates the SilcServerEntry context
1316 and saves the server info there. The COMMAND_REPLY in
1317 the INFO now returns the parameters to application in
1318 same order as defined in the protocol specification.
1320 The entries are cached in the client->server_cache.
1322 * The INFO command is now issued after received the Client ID
1323 from the server. Affected file lib/silcclient/client.c.
1325 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1326 to the application as the mode changer might be server.
1327 It is guaranteed that NULL is not returned anymore to the
1328 application. Affected file lib/silcclient/client_notify.c.
1330 The ID Type is now also passed to the application so that
1331 it can check whether the returned entry is SilcClientEntry
1334 Added new function silc_client_get_server_by_id to return
1335 the server entry by ID. Affected files are the
1336 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1338 * Do not create the channel in the Irssi SILC Client when issuing
1339 the JOIN command but when received the sucessful JOIN command
1340 reply. Otherwise the channel might get created even though we
1341 could not join it. The Affected file is
1342 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1344 * Fixed a channel joining bug in router. The router must also
1345 check the channel modes, invite and ban lists etc. when serving
1346 the JOIN command sent by normal server. Affected file is
1347 silcd/command.c. The router now resolves the client's
1348 information from the server who sent the JOIN command if it
1349 does not know it, and processes the JOIN command only after
1352 * Changed the SilcCommandCb to take new argument; void *context2.
1353 Affected file lib/silccore/silccommand.h
1355 The second argument in the command callbacks in the server now
1356 includes the SilcServerCommandReplyContext if the command was
1357 called as pending command callback from the command reply.
1358 Otherwise it is NULL. When called as pending the status of the
1359 command reply will be checked and if it was erronous the
1360 error will be sent to the original sender of the command.
1361 This way the client always receives the error messages even
1362 though the server was actually the one who received the error
1363 when it resent the command to router, for example. Affected
1364 files silcd/command[_reply].[ch].
1366 * Fixed sending WHOWAS command's error message to client if
1367 the requested client could not be found. It was missing.
1370 * Changed the CMODE and CUMODE commands reply arguments in the
1371 protocol specification. The Channel ID is now sent in both
1372 of the commands to identify the channel. Implemented this
1373 new feature to the client and server. Affected files
1374 lib/silcclient/command_reply.c and silcd/command.c.
1376 * Made better checks for invite and ban lists in the JOIN
1377 command in server. Affected file silcd/command.c.
1379 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * The server now performs the incoming host IP/DNS lookup
1382 using the silc_socket_host_lookup and thus does not block
1383 the server anymore. Affected file silcd/server.c.
1385 * Completed the multi-thread support for SILC Scheduler in
1386 the lib/silcutil/silcschedule.c.
1388 * Fixed the configure.in.pre to detect the pthread correctly
1391 * Fixed a deadlock in silc_task_queue_wakeup in the file
1392 lib/silcutil/silctask.c.
1394 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1396 * Added new function silc_schedule_wakeup that is used in
1397 multi-threaded environment to wakeup the main thread's
1398 schduler. It needs to be used when a thread adds a new task
1399 or removes a task from task queues. After waking up, the
1400 scheduler will detect the task queue changes. If threads
1401 support is not compiled in this function has no effect.
1402 Implemented the wakeup mechanism to both Unix and WIN32
1403 systems. Affected files are lib/silcutil/silcschedule.[ch],
1404 lib/silcutil/unix/silcunixschedule.c and the
1405 lib/silcutil/win32/silcwin32schedule.c.
1407 * Added new function silc_task_queue_wakeup to wakeup the
1408 scheduler by the specified task queue. Affected file
1409 lib/silcutil/silctask.[ch].
1411 * The silc_socket_host_lookup_start now wakes up the scheduler
1412 after adding the timeout task. Affected file is
1413 lib/silcutil/silcsockconn.c.
1415 * The silc_socket_host_lookup is synchronous now if the threads
1416 support is not compiled in. However, the callback is still
1417 called asyncronously through the scheduler, anyway. Affected
1418 file lib/silcutil/silcsockconn.c.
1420 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1422 * Added new function silc_socket_host_lookup to perform
1423 asynchronous IP and FQDN lookups for the socket connection.
1424 Affected files lib/silcutil/silcsockconn.[ch].
1426 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1429 that may or may not compile the mutex support in.
1431 Changed the silc_mutex_alloc interface. It allocates the
1432 mutex now to the sent pointer and returns TRUE or FALSE.
1434 Affected file lib/silcutil/silcmutex.h.
1436 * Wrote the SILC Task Queue interface to support multi-threads.
1437 Affected file lib/silcutil/silctask.[ch].
1439 * Wrote the SILC Scheduler to support multi-threads. Affected
1440 file lib/silcutil/silcschedule.c.
1442 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1445 in lib/silcutil/win32/.
1447 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * Defined SILC Mutex API and SILC Thread API and implemented
1450 them for Unix. Affected files are
1451 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1452 lib/silcutil/unix/silcunixmutex.c and
1453 lib/silcutil/unix/silcunixthread.c.
1455 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1457 * Fixed the silc_server_remove_clients_by_server's channel
1458 key re-generation. The hash table handling was incorrect
1459 and would not work with many channels. Affected file is
1462 * Fixed some memory leaks around the server code.
1464 * Rewrote the silc_server_get_users_on_channel to support IPv6
1465 based Client ID's. Affected file silcd/server.c.
1467 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1468 specification. However, a separate document must be written
1469 to define the detailed signing procedure and the payload
1470 associated with the flag. Defined the flag to the
1471 lib/silccore/silcchannel.h as well.
1473 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1475 * Changed the dynamic tables to static size tables in the
1476 lib/silccrypt/silchmac.c.
1478 * Removed GCC dependencies from the code. A patch by cras.
1480 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1482 * Do not show the error "Error receiving packet bla bla"
1483 in server if it really was not an error (-2 means that reading
1484 is pending). Affected file silcd/server.c.
1486 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1488 * Fixed a possible crash in silc_server_remove_clients_by_server
1489 in silcd/server.c. Fixed there also some memory leaks.
1491 * Fixed the silc_idlist_replace_client_id. It could replace
1492 wrong key in the hash table. Affected file silcd/idlist.c.
1494 * Do not check whether there are global users on the channel
1495 if the channel->global_users is FALSE. Affected functions
1496 silc_server_remove_from_one_channel and
1497 silc_server_remove_from_channels in silcd/server.c. Also,
1498 do not check if the removed client is local as we can be
1499 sure that global client was not removed from the channel
1500 and checking for global users is not needed.
1502 * The silc_server_remove_clients_by_server now re-generates
1503 the channel keys correctly for those channels that had
1504 clients removed from them. Affected file silcd/server.c.
1506 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1508 * Found the reason of random crashes in the server. We weren't
1509 ignoring the SIGPIPE signal (which can be sent in write())
1510 and it crashed the server. Affected file silcd/silcd.c.
1512 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Assure that sock->user_data is not NULL in the function
1515 silc_server_packet_send in silcd/packet_send.c.
1517 * Disconnect the remote connection if it could not be added
1518 to any ID lists in the server. The affected file is
1521 * Check in silc_server_packet_send[_real/dest] that the
1522 socket is not disconnecting and ignore the data if it is.
1523 Affected file silcd/packet_send.c.
1525 * Define inline to __inline on native WIN32 compilation.
1526 Affected file includes/silcwin32.h.
1528 * Added some explicit type casts for inline code since MSVC
1529 require them. Affected files lib/silcutil/silcbuffer.h,
1530 lib/trq/silcdlist.h and lib/trq/silclist.h.
1532 * Print warning in log files from now on if the packet
1533 decryption fails. Affected file silcd/server.c.
1535 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Changed the `say' client operation's interface to accept
1538 new `type' argument to indicate the type of the message sent
1539 by the library. The application may filter the library's
1540 messages according the type. The affected file is the
1541 lib/silcclient/silcapi.h.
1543 * Added two new functions to lib/silcclient/silcapi.h:
1544 silc_client_del_client and silc_client_del_client_by_id.
1545 Affected file lib/silcclient/idlist.c.
1547 * Moved the clientincludes.h from includes/ to silc/ and
1548 serverincludes.h from includes/ to silcd/.
1550 * The modes for the CMODE and CUMODE are now passed as
1551 uint32 for application with COMMAND_REPLY. The affected
1552 file is lib/silcclient/command_reply.c.
1554 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * /WHOIS without arguments shows client's own information.
1557 Affected file lib/silcclient/command.c.
1559 * Changed PING to not accept any arguments. The specs
1560 says that client can ping only the connected server so
1561 requiring an argument is not needed. Affected file is
1562 lib/silcclient/command.c.
1564 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1566 * Fixed a fatal bug in private message sending and reception
1567 encryption and decryption when using private message keys.
1568 The implementation was incorrect and did not follow the
1569 specification. It causd that some of the message were
1570 lost since it did not use the sending and receiving keys
1571 as the protocol suggests. This has been fixed and will cause
1572 incompatibilities with older clients when sending private
1573 message encrypted with private message keys. Affected files
1574 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1575 and various other in Irssi SILC Client.
1577 Added `responder' boolean argument to the functions
1578 silc_client_add_private_message_key[_ske] to indicate when
1579 the key is added as responder or initiator of the key
1582 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * Removed the silc_ske_check_version function and created
1585 a SilcSKECheckVersion callback. Added also a function
1586 silc_ske_set_callbacks that is now used to set all SKE
1587 callbacks. The callback functions are not given to
1588 the SKE functions anymore, but this function is used to
1591 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1593 * Added `silc_version' argument to the silc_client_alloc
1594 to define the version of the application for the library.
1595 The library will use the version string to compare it
1596 against the remote host's (usually a server) version
1597 string. Affected file lib/silcclient/silcapi.h
1599 * Added the KE protocol context to Key Agreement context
1600 in client library so that we can abort the SKE if it
1601 is in process when we get timeout. Affected file is
1602 lib/silcclient/client_keyagr.c.
1604 * Do not resolve the client ID forever if it returns in the
1605 first time that such client does not exist. This was done
1606 for example with private message. Affected file is
1607 lib/silcclient/client_prvmsg.c.
1609 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Do not add regex.h for WIN32. The affected file
1612 includes/silcincludes.h.
1614 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1615 not work yet 100%. It generates the DLL's automatically
1616 when compiling with --with-win32 under cygwin.
1618 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1620 * lib/contrib/regex.c is not compiled on WIN32.
1622 * Added silc_net_get_socket_opt function to the
1623 lib/silcutil/silcnet.h.
1625 * Added includes/silcwin32.h for WIN32 specific includes
1628 * Do not use ptime structure or any of the posix process
1629 functions on WIN32 in lib/silccrypt/silrng.c.
1631 * Added silc_gettimeofday to provide generic function
1632 for struct timeval on all platforms. Added the function
1633 to lib/silcutil/silcutil.h.
1635 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1638 library as they clearly belong there. As a plus side we
1639 can make the actual socket connection routines platform
1642 Added also new generic function silc_socket_read and
1643 silc_socket_write (that used to be silc_packet_[read/write].
1644 The implementation of these are platform specific.
1646 * Added WIN32 specific routines of silc_socket_[read/write]
1647 to lib/silcutil/win32/silcwin32sockconn.c.
1649 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * Added preliminary support for native WIN32 compilation under
1652 cygwin (using the -mno-cygwin option for GCC) to the
1653 ./configure.in.pre. The --with-win32 now prepares the
1654 compilation for native WIN32.
1656 * Rewrote the SILC Scheduler interface in the file
1657 lib/silcutil/silcschedule.h. The scheduler is now context
1658 based and does not have anymore any global static scheduler.
1659 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1660 and created lib/silcutil/win32 directory for WIN32 based
1663 * Added Unix specific network routines to the
1664 lib/silcutil/unix/silcunixnet.c and the old
1665 lib/silcutil/silcnet.c includes now only generic routines.
1667 Added WIN32 specific network routines to the
1668 lib/silcutil/win32/silcwin32net.c.
1670 * Added Unix specific utility functions from the
1671 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1673 * Added WIN32 SILC Scheduler to the file
1674 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1677 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Do not handle JOIN notify in the server if the target client
1680 is not registered (idata->registered == FALSE). The affected
1681 file is silcd/packet_receive.c.
1683 * Update the nickrec->founder in event_cumode in the Irssi SILC
1684 client. Affected file irssi/src/silc/core/silc-channels.c.
1686 * Fixed the CUMODE_CHANGE notify handling in the server when
1687 server and router are announcing their clients on channels.
1688 Now the mode changes are saved and notified correctly. The
1689 affected file is /silcd/packet_receive.c.
1691 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1692 They really did not replace the cache entry in the ID Cache.
1693 Now they do that. Affected file silcd/idlist.c.
1695 * Fixed the KICK notify handling in the Irssi SILC client to
1696 update the channel records so that the kicked client does not
1697 appear to be on the channel. The affected file is
1698 irssi/src/silc/core/silc-channels.c.
1700 * Always update the conn->current_channel when executing command
1701 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1703 * Fixed the KILL notify handling in Irssi SILC client to remove
1704 the killed client on all channels.
1706 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Fixed the silc_parse_command_line to remove extra spaces
1709 from the start and end of the arguments. Affected file is
1710 lib/silcutil/silcutil.c.
1712 * Cancel and free any active protocol in the function
1713 silc_server_close_connection. Affected file silcd/server.c.
1715 * Cancel and free any active protocol in the function
1716 silc_client_close_connction. Affected file is
1717 lib/silcclient/client.c.
1719 * Do not execute the KILL command for clients that are in
1720 history (ie. they are not in the network). Affected file is
1723 * Fixed KILL notify handling, client does not crash anymore.
1724 Affected file irssi/src/silc/core/silc-channels.c.
1726 * Reduced the default packet buffer size from 2048 to 1024 in
1727 lib/silccore/silcpacket.c.
1729 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1730 counter to the SKE context that is incresed when the SKE library
1731 performs async operation outside the library. If the outside
1732 process frees the SKE context and FREED status will be set
1733 and the library will detect after the sync operation that the
1734 libary is freed. The affected files are
1735 lib/silcske/silcske[_status].[ch].
1737 * Resolve the client entry information in the function
1738 silc_client_channel_message to assure that NULL pointer is not
1739 passed as client entry to the application. */
1741 * Fixed the task timeout calculation to assure that there is
1742 never negative timeouts. The affected file is
1743 lib/silcutil/silcschedule.c.
1745 * Fixed the channel user mode notification sending in server.
1746 It was sent point-to-point to the router (or to server by router)
1747 but it needs to be destined to a channel. The routines now
1748 supports sending the channel user mode notifys to the channels
1749 when announcing clients and channels. Affected files are
1750 silcd/server.c and silcd/packet_receive.c.
1752 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1753 It did not actually replace the old channel entry in the cache.
1754 Affected file lib/silcclient/client_notify.c.
1756 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Fixed a possible crash in silc_packet_send_prepare. It now
1759 assures always that there is enough space in the buffer and
1760 at the tail area of the buffer (for MAC).
1762 Fixed the inbound buffer reallocation in silc_packet_read.
1763 It was old code and did not handle the reallocation correctly.
1766 The affected file is lib/silccore/silcpacket.c.
1768 * Fixed buffer overflow in silc_parse_nickname in the file
1769 lib/silcutil/silcutil.c.
1771 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * make install generates new server keys only if there is not
1776 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1779 Added check that if the NOREPLY is set then we will not send
1780 the away message. This avoids infinite loop of away messages
1781 if both clients are away. The affected file is
1782 lib/silcclient/client_prvmsg.c.
1784 * Fixed client crash if /NICK was given without arguments.
1785 Affected file lib/silcclient/command.c.
1787 * Server does not send the invite list in INVITE command back
1788 to the client if the list was not altered. Added this notion
1789 to the protocol spec as well. Affected file silcd/command.c.
1791 Fixed possible crash in INVITE command by checking the
1792 value of silc_server_get_client_route command.
1794 * Fixed the INVITE notify type handling. The arguments are now
1795 taken in correct order and client does not crash. The affected
1796 file is irssi/src/silc/core/silc-channels.c.
1798 Removed the "Inviting xxx to channel" message from the
1799 client library away and let the application handle it.
1800 Affected file lib/silcclient/command.c. Added that message
1801 to Irssi SILC client's message formats.
1803 * Fixed CMODE command crash in client. It now checks the
1804 amount of arguments correctly and does not crash. The affected
1805 file is lib/silcclient/command.c.
1807 * Do not create new channel automatically in silc_channels_join
1808 but check whether the channel by that name already exists.
1809 Affected file irssi/silc/core/silc-channels.c.
1811 * Do not send the SERVER_SIGNOFF to router if the disconnected
1812 entity was the router. Affected file silcd/server.c.
1814 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1815 SILC client as it was missing from there.
1817 Added the handling of the KICK notify to the Irssi SILC client
1818 as it was missing. Added "you have been kicked" message to
1819 Irssi SILC client's message modules formats.
1821 Added the handing of the KILL notify to the Irssi SILC client
1822 as it was missing. Added the kill message module formats
1825 The affected file is irssi/src/silc/core/silc-channels.c.
1827 * The router did not save the channel mode the server announced.
1828 Affected file silcd/packet_receive.c.
1830 * Fixed a possible crash in INFO command in server. If the
1831 server did not provide the server info it crashed. Affected
1832 file silcd/command.c.
1834 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Fixed the GETKEY command in the server to check also the
1837 global list. Otherwise the GETKEY would not work correctly
1838 in normal SILC server. Affected file silcd/command.c.
1840 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1842 * Fixed GETKEY crash, it crashed if the command did not succseed.
1844 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1847 is now real and not just an macro interface to GMP.
1849 Removed the entire GMP from the source tree and imported new
1850 NSS MPI library instead. Reason for removing GMP is that it is
1851 extremely large and compiles extremely slow. The NSS MPI
1852 is only a few files and compiles in less than 10 seconds.
1853 The speed is also about the same as GMP. The MPI is imported
1854 to lib/silcmath/mpi.
1856 If the system has GMP installed we will still use the GMP.
1857 If it is not then the NSS MPI will be compiled.
1859 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Merged a long nickname (127 characters long) crash bugfix from
1862 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1864 * Merged a freed memory reference bugfix from Irssi CVS tree.
1865 Affected file irssi/src/core/commands.c.
1867 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Added the server's public key sving and verification to the
1870 server when performing the SKE. This was missing and the
1871 remote server's (or router's) public key was accepted without
1872 checking whether we have it previously or trust it at all.
1873 Affected file silcd/protocol.c.
1875 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Check in the silc_server_timeout_remote if protocol is active
1878 and make sure that the protocol's final callback is called so
1879 that all memory if freed. Affected file silcd/server.c.
1881 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * silc_server_whois_send_reply crashed the server if the nickname
1884 was 127 characters long. Affected file silcd/command.c.
1886 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Added sanity check to the silc_server_new_client. If the hostname
1889 is provided inside username then check that the provided hostname
1890 really is the same as the resolved one. If the hostname was not
1891 resolved then check it from the public key. Affected file is
1892 silcd/packet_receive.c.
1894 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1895 if the server disconnected us and the connection is not valid
1896 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1898 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1899 the library to the lib/silcutil/silcutil.[ch].
1901 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Close log file after open. Affected file
1904 lib/silcutil/silclog.c.
1906 * Check whether sock == NULL in silc_client_send_packet and return
1907 if it is. Affected file lib/silcclient/silcclient.c.
1909 * Check rec->entry == NULL in the Irssi SILC Client before
1910 sending the channel message. Affecte file is
1911 irssi/src/silc/core/silc-servers.c.
1913 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Merged a splitted window bugfix from Irssi CVS tree. The
1916 affected file is irssi/src/fe-text/textbuffer-view.c.
1918 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1919 It did not print nickname.
1921 * Improved the distributions system a bit.
1923 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1926 irssi/src/fe-text/gui-window.c.
1928 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1929 to in-active server. The affected file is
1930 irssi/src/silc/core/client_ops.c.
1932 * Resolve the client in USERS command reply if the entry does
1933 not have username resolved. The affected file is
1934 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1935 command to WHOIS command to really resolve stuff. The USERS
1936 is not used any more in any critical section so WHOIS can
1937 be used even though it might be slower than IDENTIFY.
1939 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1942 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1944 * Changed the protocol API a bit more consistent in the
1945 lib/silccore/silcprotocol.[ch].
1947 * Changed the following headers to ROBODoc format:
1949 lib/silccore/silcpayload.h
1950 lib/silccore/silcprotocol.h
1951 lib/silccore/silcsockconn.h
1953 All core library headers are now formatted.
1955 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Fixed a bug in Irssi SILC client; do not show that you are
1958 server/router operator if you really are not. Affected file is
1959 irssi/src/silc/core/client_ops.c.
1961 * Renamed silc_command_free_payload to silc_command_payload_free.
1962 Affected file lib/silccore/silccommand.h
1964 * Added silcmath.h to include the prototoypes of various routines
1965 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1968 * Changed the following headers to ROBODoc format:
1970 lib/silccore/silcchannel.h
1971 lib/silccore/silccommand.h
1972 lib/silccore/silcid.h
1973 lib/silccore/silcidcache.h
1974 lib/silccore/silcmode.h
1975 lib/silccore/silcnotify.h
1976 lib/silccore/silcpacket.h
1977 lib/silcmath/silcmath.h
1979 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Added checking to the server code not to start the server if
1982 ciphers and stuff are not configured properly. Affected files
1983 silcd/serverconfig.[h] and silcd/server.c.
1985 * Changed the layout of the header files of the public interfaces
1986 in the SILC libraries. The new layout supports ROBODoc
1987 documentation tool (and some others) so that it is easy to create
1988 a library reference manual. All the other headers and source
1989 code must still follow the CodingStyle document. Also source
1990 code must not include these ROBODoc stuffs, only the headers.
1991 Furthermore, all public interface headers must now be named
1992 by using `silc' prefix, example: silcapi.h, silccipher.h.
1993 Some files were renamed due to this. All the other headers
1994 must not be used as public interfaces. I will update the
1995 CodingStyle document later. Changed following headers, so far:
1997 lib/silcclient/silcapi.h
1998 lib/silccore/silcauth.h
1999 lib/silccore/silcprivate.h
2000 lib/silccrypt/silcdh.h
2002 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Removed silc_client_packet_send_flush from the client library
2007 as it is not needed. Affected file lib/silcclient/client.[ch].
2009 * Added printing of message of unresolved authentication method
2010 to the Irssi SILC client. Added it to the module formats.
2011 Removed the same message from the client library.
2013 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Added new distribution feature, DISTLABEL. Every distribution
2016 can define own preprocessor label that can be used in the
2017 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2018 file distributions, acconfig.h.pre and prepare.
2020 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Added Makefile.defines_int to include the actual definitions
2023 for Makefile.defines.in. Tested the new distribution system,
2024 created distributions and tested installation.
2026 * Added AWAY message printing to the Irssi SILC client. Added
2027 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2029 * Added SCONNECT command to call the SILC's CONNECT command.
2030 Cannot use CONNECT directly since Irssi uses that internally.
2031 Affected file irssi/src/silc/core/silc-servers.c.
2033 Added ACTION local command. It is same as ME command but takes
2034 the channel as mandatory argument.
2036 Rewrote some of the Irssi's help files to suite for SILC
2039 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Added Makefile.defines[.in] that should for now on be included
2042 in all Makefile.am file in the source tree. That file includes
2043 all common compilation definitions for SILC source tree.
2045 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Minor changes to the ./prepare script to change the package
2048 name according the distribution name to the configure.in.
2050 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Created new distribution system. Added file `distributions'
2053 that defines all the distributions that can be created out of
2054 the SILC source tree. The ./prepare script now reads that
2055 file to determine how to prepare the distributions. The
2056 first argument to the ./prepare is the name of the distribution
2057 and second is the version of the distribution. If given
2058 without arguments it creates the default (toolkit) distribution
2059 with the default version (defined in ./prepare).
2061 All Makefile.am files that are subject to the distributions
2062 are now named as Makefile.am.pre. These are ./Makefile.am
2063 and lib/Makefile.am. Others may be changed later.
2065 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Added invite list, ban list, some key management and connection
2068 error message printing to module formats in the Irssi SILC client.
2070 * Added new silc_client_set_away_message to set the away message
2071 that is back to the person who sent private message. The
2072 affected file lib/silcclient/silcapi.h and the
2073 lib/silcclient/client_prvmsg.c.
2075 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2077 * Fixed the private message sending in the Irssi SILC client,
2078 added local command KEY to the Irssi SILC client.
2080 Added key management and key agreement message formats to the
2081 irssi/src/fe-common/silc/module-formats.[ch].
2083 Added USERS (alias WHO) printing, server/router operator
2084 indication and LIST command printing to the module formats.
2086 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Fixed channel joining notify handling, cumode notify handling
2089 from Irssi SILC client.
2091 * Added SILC specific module-formats to the Irssi SILC client so
2092 that SILC specific message hilighting, colors etc is possible.
2093 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2095 Added channel mode, channel user mode, actions, notices,
2096 whois and whowas printing to the the module-formats.c.
2098 * Fixed a bug in channel deletion in the server. The channel
2099 is not left to the cache even if the channel founder auth mode
2100 is set when there are no users anymore on the channel. Affected
2101 file silcd/server.c.
2103 * The silc_net_localhost now resolves the entire hostname including
2104 the domain name. Affected file lib/silcutil/silcnet.c.
2106 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Changed the ask_passphrase client operation to be ascynchronous.
2109 It has now a completion callback and a context that the
2110 application must call after it has got the passphrase from
2111 the user. Affected files lib/silcclient/silcapi.h,
2112 lib/silcclient/protocol.c, lib/silcclient/command.c and
2115 Added SilcAskPassphrase callback that the application calls
2116 to deliver the passphrase to the library.
2118 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2119 The public key verification and especially a certificate
2120 verification is asynchronous procedure.
2122 Added new SILC_SKE_STATUS_PENDING status to indicate the
2123 request is pending and a callback will be called to finalize
2126 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2127 indicate that remote end did not send its public key (or
2128 certificate), even though we require it. Added check for this
2129 condition in the SKE. This was a security bug, now fixed.
2131 Defined new SilcSKEVerifyCbCompletion callback that is called
2132 when the verification process is completed.
2134 The affected files lib/silcske/silcske_status.h and
2135 lib/silcske/silcske.[ch].
2137 * Changed the verify_public_key client operation to be async
2138 as well. Defined SilcVerifyPublicKey callback that is used to
2139 indicate the success of the public key verification process.
2141 Changed the server and client to use the new async client
2144 * Changed the Irssi SILC client's internal scheduler to be called
2145 twice as many times as it used to be. As a result the client
2146 should be a bit faster now. Affected file is
2147 irssi/src/silc/core/silc-core.c.
2149 * Added support to Irssi SILC client of asynchronous public key
2150 verification and passphrase inquiry. Affected file is
2151 irssi/src/silc/core/silc-core.c.
2153 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2155 * Do not say "You have left channel %s" in client library.
2156 Moved it to the application. Affected files are
2157 lib/silcclient/command.c and silc/client_ops.c.
2159 * Fixed silc_client_get_clients. Command context was not
2160 duplicated and was freed memory in the callback. Affected
2161 file lib/silcclient/idlist.c.
2163 * Do not say "you are now talking..." on JOIN command in the
2164 client library. The appliation must handle it.
2166 * Do not say ".. changed topic to" in command reply in the
2167 client libary. The application must handle it.
2169 * Fixed TOPIC command sending in the client library.
2171 * Fixed a memory leak in silc_client_command_free in the file
2172 lib/silcclient/command.c.
2174 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Imported a modified version of Irssi client to the source tree.
2177 The Irssi will be used to create a new client called
2178 Irssi SILC. Imported to irssi/.
2180 Added silc_core_init_finish function to the Irssi. Affected
2181 file irssi/configure.in.
2183 A lot changes in the Makefile.ams around the irssi tree.
2185 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Do not rehash if the new size is same as the old size of the
2188 hash table, in the silc_hash_table_rehash*. The affected file
2189 lib/silcutil/silchashtable.c.
2191 * Replaced hash_table_del_by_context calls from the server
2192 (when channel->user_list and client->channels) to the
2193 hash_table_del as it is sufficient and faster.
2195 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Added silc_hash_table_list, silc_hash_table_get and the
2198 SilcHashTableList structure to provide an alternative way to
2199 traverse the hash table. The affected files are
2200 lib/silcutil/silchashtable.[ch].
2202 * Changed the server's idlist routines to use the hash table
2203 routines to optimize the code.
2205 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Replaced the client entry's `channel' list and channel entry's
2208 `user_list' list to hash tables for optimized lookup. Changed
2209 the code to use the hash table interface around the code.
2210 Affected file lib/silcd/idlist.[ch].
2212 * Added `auto_rehash' boolean argument to the function
2213 silc_hash_table_alloc to indicate whether the hash table should
2214 auto-rehash when it thinks is appropriate time. It will
2215 increase the hash table size if the there is twice as much
2216 entries in the table than the size of the table, and will
2217 decrease the size if there are twice as less entries than
2218 the size of the table.
2220 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2222 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2224 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * silc_idcache_purge_by_context deletes the entry now by context
2227 as it is supposed to do. Affected file lib/silccore/idcache.c.
2229 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2230 client is not anymore valid (WHOWAS givens the info) and not
2231 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2233 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Removed the `data' and `data_len' arguments from the ID Cache
2236 interfaces and added `name' argument. ID Cache does not handle
2237 anymore the binary data only a names associated with given ID.
2239 * When hashing a Client ID with silc_hash_id the entire ID is
2240 not hashed anymore, instead only the hash of the Client ID is
2241 hashed. This way we can access the Client ID from the cache
2242 with Client ID but with the hash of the ID (which is a hash of
2243 the nickname) as well without any difference in performance.
2245 Added also silc_idcache_find_by_id_one_ext to do one on one
2246 searching when we have the actual ID. Added also function
2247 silc_hash_client_id_compare. The affected files are
2248 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2250 * When hashing the name associated with a ID it is always done
2251 in lowercase. This way we can access the cache without worrying
2252 about case-sensitivity, even though, for example nicknames are
2255 * Fixed a bug in server with channel message sending. It put
2256 wrong ID type as destination ID. The affected file
2257 silcd/packet_send.c.
2259 * silc_idcache_del_by_context now deletes from all hash tables
2260 by context. Affected file lib/silccore/idcache.c.
2262 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Changed the client library to use the new ID Cache interface.
2265 Changes around the source tree.
2267 * Added silc_hash_table_rehash_ext to rehash with specific
2268 hash function. Affected file lib/silcutil/silchashtable.[ch].
2270 * Added silc_hash_string_compare to compare two strings in the
2271 hash table. Affected file lib/silcutil/silcutil.[ch].
2273 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * Added new function silc_idcache_del_by_context into the
2276 lib/silccore/idcache.[ch].
2278 * Changed the server's ID list routines to use the new ID Cache
2279 interface. Changes around the source tree.
2281 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added silc_hash_table_del[_by_context]_ext functions in to the
2284 lib/silcutil/silchashtable.[ch].
2286 Removed silc_hash_table_find_all* routines and added new
2287 silc_hash_table_find_foreach to replace them.
2289 Added silc_hash_table_replace_ext function as extended
2290 replacing function. Separated the simple hash table interface
2291 from the extended hash table interface in the file
2292 lib/silcutil/silchashtable.h.
2294 * Fixed minor bugs and changed it to use some of the new
2295 hash table functions in lib/silccore/idcache.c
2297 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Added new function silc_hash_table_find_all to return all keys
2300 in the hash table by the specified key. As the hash table is
2301 collision resistant it also makes it possible to have several
2302 duplicate keys in the hash table. This function may be used to
2303 find all of the keys from the hash.
2305 Added user_context arguments to the SilcHashFunction,
2306 SilcHashCompare and SilcHashDestructor to deliver user specified
2309 Added new fuctions silc_hash_table_find[_all]_ext to do
2310 extended lookup with specified hash and compare functions and
2311 specified user contexts.
2313 Added new function silc_hash_table_add_ext to add the key
2314 with specified hash function and user context.
2316 Added new function silc_hash_table_foreach to traverse all
2317 entrys in the hash table. Added SilcHashForeach callback
2320 Added new function silc_hash_table_del_by_context to delete
2321 the entry only if the context associated with the key matches.
2323 Affected files are lib/silcutil/silchashtable.[ch].
2325 * Removed silc_hash_[server/client/channel]_id and added just
2326 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2327 silc_hash_id_compare to compare two ID's using as the hash table
2328 comparison function. Added also silc_hash_data to hash
2329 binary data and silc_hash_data_compare to compare it.
2331 * Removed silc_idlist_find_client_by_hash as it is not needed
2332 anymore. Affected file silcd/idlist.[ch].
2334 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2335 to use internally the SilcHashTable. The new ID Cache is a lot
2336 faster than the old one. Some of the ID Cache interface was also
2337 rewritten and obsolete and stupid functions were removed.
2339 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Added entry_count field to the SilcHashTable to keep the number
2342 of the entries in the table. Implemented the function
2343 silc_hash_table_rehash. Added new function
2344 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2346 Fixed a minor bug in silc_hash_table_free.
2348 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2349 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2350 into the lib/silcutil/silcutil.[ch].
2352 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Implemented a collision resistant hash table into the
2355 lib/silcutil/silchashtable[ch]. See the header and the source
2356 for the SilcHashTable API.
2358 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2360 * Merged dotconf version 1.0.2 into lib/dotconf.
2362 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Do not compile anything in lib/silcsim/* if the SIM support
2365 is not enabled. The tree should now compile without problems
2368 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Compiled the SILC under cygwin. Compiled and tested briefly
2371 without problems. More tests needed. The SIMs didn't compile
2374 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2376 * Fixed possible crash in silc_get_username in the
2377 lib/silcutil/silcutil.c.
2379 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Fixed a va_arg in silc/client_ops.c.
2383 * Oops, RC5 routines were named AES and caused some problems
2384 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2386 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2388 * Added new SilcIDIP structure into the lib/silccore/id.h and
2389 replaced the old `ip' fields from all SILC ID's to that type.
2390 This is a step towards IPv6 support.
2392 The silc_id_get_len takes now the ID as an extra argument.
2393 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2394 both IPv4 and IPv6 based ID's.
2396 The affected files are lib/silccore/id.[ch] and other files
2397 around the tree using these routines.
2399 * Removed the ID length arguments in server from various
2400 silc_server_send_notify_* routines -> they are not needed
2403 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Fixed memory leak in silc_encode_pem_file in the file
2406 lib/silcutil/silcutil.c.
2408 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Check minor version as well in the SKE. Affected files are
2411 silcd/protocol.c and lib/silcclient/protocol.c.
2413 * Added --identifier option to the server so that an identifier
2414 can be when creating the public key for the server. Affected
2415 file is silcd/silcd.c.
2417 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2418 lib/silccrypt/silcpkcs.c.
2420 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Register default ciphers and stuff when using -C option with
2423 the server. Affected file sildc/silcd.c.
2425 * Put back the servers public key filename format, it is better
2426 than the new one. For now, the client keys are saved with the
2427 new filename format. The affected file silc/client_ops.c.
2429 * Implemented the Cipher API for the rest of the ciphers that
2430 did not implement it or implemented it the wrong way.
2432 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Register default ciphers and stuff when using the -S option
2435 in the client. Affected file silc/silc.c. Same also when
2436 creating new key pair with -C option.
2438 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Fixed the silc_verify_public_key client operation function to
2441 save the public keys differently. The fingerprint is now
2442 used as filename and not the hostname. This way also the
2443 client keys are saved uniquely and not with hostnames. The
2444 affected file is silc/client_ops.c.
2446 * Trimmed the silc_hash_fingerprint function to remove extra
2447 whitespaces from the end of the fingerprint. The affected
2448 file is lib/silccrypt/silchash.c.
2452 * Added silc_cipher_register_default function to register all
2453 default ciphers. It can be used when configuration files
2454 does not exist and the application does not want any specific
2455 ciphers in any specific order.
2457 The SilcDList is now used as silc_cipher_list dynamically
2458 allocated cipher list. Removed the static list all together
2459 and now all ciphers must be allocated to the dynamic list.
2460 The silc_cipher_alloc routine was changed to check only the
2463 All silc_cipher_* routines that used to return int returns
2466 The affected files lib/silccrypt/silccrypt.[ch].
2468 * The same thing was done to silc_hash_* as for silc_cipher_*
2469 routines. Affected files lib/silccrypt/silchash.[ch].
2471 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2472 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2473 Added also silc_pkcs_[un]register[_default] functions.
2474 Removed the data_context from the PKCS API.
2476 * Added silc_hmac_register_default function to register default
2477 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2478 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2479 to unregister all hmacs at once.
2481 * Register the default ciphers, hash functions, PKCSs and HMACs
2482 if client's configuration file does not exist. The affected
2485 * The client did not load the hash functions from the SIM
2486 modules at all. Added support for this. Affected file is
2487 silc/clientconfig.c.
2489 * When decoding public key with silc_pkcs_public_key_decode, check
2490 the supported algorithm only if PKCS are registered. Affected
2491 file lib/silccrypt/silcpkcs.c. The same was done with the
2492 silc_pkcs_private_key_decode.
2494 * Fixed the SILC List routines to keep the list always in order.
2495 It used to change the list's order when traversing the list but
2496 not it preserves the order. Affected file lib/trq/silclist.h.
2498 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2500 * Added the client library to use the SilcSocketConnection's
2501 reference counter (by silc_socket_dup) to prevent the bug that
2502 the socket object may be freed underneath async operation.
2504 * The name resolv library checking fixes in the configure.in.pre.
2507 * Created new version of the protocol drafts for future
2508 development. The -03 drafts are the ones that will be changed
2509 in the trunk now and the -02 will remain as they are.
2511 * Send list of CUMODE notifys to the router when announcing
2512 the channel users to the router. Affected file silcd/server.c.
2513 If the router receiving channel founder CUMODE for a channel
2514 that already has channel founder it will send CUMODE notify
2515 to the sender to remove the channel founder rights from the
2516 announced client. Affected file silcd/packet_receive.c.
2518 * The CUMODE notify may now use Server ID as well as the entity
2519 who changes the mode. Updated protocool specs.
2521 * Updated INSTALL and README files.
2523 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * New web pages in the http://silc.pspt.fi. The pages was
2530 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2532 * Implemented the [DenyConnectin] config section in the server.
2533 Added silc_server_config_denied_conn to check whether incoming
2534 connection is denied. Affected file silcd/serverconfig.[ch].
2536 * Do not check the ports when checking the incoming configuration
2537 data if the port is 0, meaning any. Affected file is
2538 silcd/serverconfig.c.
2540 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * Fixed buffer overflow in silc_string_compare in the file
2543 lib/silcutil/silcutil.c.
2545 * Fixed double free in silc_server_command_leave in the file
2548 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Fixed the version checking in the server. Affected file is
2553 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2555 * Fixed the configuration data fetching when accepting new
2556 connections in the server. Affected file silcd/server.c.
2558 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Added `sender_entry' argument to the function
2561 silc_server_packet_relay_to_channel so that we can check
2562 whether some destination actually belongs to the same route
2563 the sender belongs (ie, we must not resend the packet to the
2564 sender). Affected file silcd/packet_send.[ch].
2566 * Added `servername' field to the SilcClientEntry in the server
2567 to hold the name of the server where client is from. Affected
2568 file is silcd/idlist.h.
2570 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Moved the channel message encrypting in the router betwen
2573 router connections from silc_server_channel_message to the
2574 silc_server_packet_relay_to_channel since we want to check
2575 whether we have anybody channel before encrypting anything.
2576 Affected files silcd/packet_[receive/send].c.
2578 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2580 * Fixed the [AdminConnection] server config section to support
2581 multiple entries. Affected file silcd/serverconfig.c.
2583 * Added support into the server to check the validity of the
2584 incoming connection before executing any KE or authentication
2587 * The connection configuration is now saved to the KE and
2588 connection auth protocol contexts and not fetched anymore in
2589 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2591 * The local hosts listenning address and port is also resolved
2592 now when starting the server. We want to have the socket object
2593 to include the real address and port for the listener. Added
2594 new function silc_net_check_local_by_sock into the files
2595 lib/silcutil/silcnet.[ch].
2597 * Fixed a broadcast bug in server -> do not broadcast if we
2600 * Fixed a routing bug. Do not route broadcast packets ever.
2601 Broadcast packets must be processed always and not routed since
2602 they may be destined to some other host than yourself and thus
2603 would get routed without no good reason. Affected file is
2606 * Added function silc_server_config_is_primary_route to check
2607 whether primary router connection has been configured (a router
2608 configuration that we are initiating). If there is not, we
2609 will assume that there is only two routers in the SILC network
2610 and we will use the incoming router connection as our primary
2611 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2613 * Changed the order of the broadcasting. Broadcast _after_ the
2614 packet has been processed not before. Affected file is
2617 * Fixed a [ClientConnection] parsing bug. The port was never
2618 parsed correctly thus resulting to port 0. Affected file
2619 silcd/serverconfig.c.
2621 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2622 argument and did not set the broadcast packet flag. Affected
2623 file silcd/packet_send.c. Fixed same bug in the function
2624 silc_server_send_notify as well.
2626 * If we receive NEW_ID packet for our own ID in the server, ignore
2629 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Removed the nickname from the Private Message Payload.
2634 Updated the code and the protocol specs.
2636 * Updated protocol specs for submitting to the IETF.
2638 * Tweaked the Random Number Generator a bit. Affected file
2639 lib/silccrypt/silcrng.c. Exported a new function
2640 silc_rng_[global]_add_noise which can be used to add more
2643 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2645 * Do not parse packets with different timeout when protocol
2646 is active -> may cause problem with rekey. Affected file
2649 * When server receives signoff notify it must not create
2650 new channel key if the client is on any channels since the
2651 sender of the signoff notify will create it.
2653 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * Added printing of error messages during SKE protocol from the
2656 failure packet sent by server during SKE. Affected file
2659 * Removed the client's failure_callback handling with timeout
2660 and handle it immediately when received.
2662 * The SKE library returned wrong type in SUCCESS and FAILURE
2663 packets. They must be 32 bit MSB not 16 bit MSB.
2665 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2667 * Ok, rewrote the logic of the re-key and now it seems to work.
2668 I tested it on high traffic with frequent re-keys without
2669 problems. Added hmac_receive (and renamed hmac to hmac_send)
2670 in SilcClientConnection in lib/silcclient/client.h and
2671 in SilcIDListData in silcd/idlist.h. Also, removed the
2672 SilcPacketParserContext's cipher and hmac fields as they are
2673 not needed anymore and actually caused some problems when
2674 the ciphers and hmac's changed underneath the packet parser.
2676 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2678 * If re-key protocol is active then process the incoming packets
2679 synchronously since we must assure that icoming packets encrypted
2680 with the old key is processed before the new keys is set to
2681 use. This is true other packets than for REKEY packets.
2682 Affected file silcd/server.c. The same was done to client library
2683 as well, affected file lib/silcclient/client.c.
2685 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2687 * Fixed bug in client and server to accept the force send if
2688 the packet is send from silc_[server/client]_packet_process
2689 function. Otherwise the packets are never delivered, oops.
2691 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2693 * Disable force sending of packets when REKEY protocol is active.
2694 We must assure that no packet is sent directly when rekey is
2695 performed. All packets must be sent through packet queue.
2696 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2697 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2698 function is silc_[server/client]_packet_send_real to check
2701 * Replaced the SIM paths from example config files to
2702 /usr/local/modules. Also, make install creates now
2703 /usr/local/silc/logs directory to hold all the SILC server
2706 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2708 * Made the configure.in.pre work on Solaris. Patch by salo.
2710 * Made all ciphers compatible with non-x86 machines. Defined
2711 CBC mode macros into lib/silccrypt/ciphers_def.h.
2713 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2715 * Fixed the make install.
2717 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * When MAC computation fails the silc_packet_decrypt returned 0
2720 even though it was supposed to return -1. Fixed this. The
2721 affected file is lib/silccore/silcpacket.c.
2723 * Do not replace the config files in /etc/silc (in make install)
2724 if they already exist. Affected file ./Makefile.am.
2726 * Do not send re-key packets immediately but through packet queue.
2727 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2729 * Changed silc_net_check_host_by_sock to return FALSE if the
2730 IP/DNS could not be resolved. Though, it returns the IP address
2731 now even if it could not resolve it (but returns also FALSE).
2732 Affected file lib/silcutil/silcnet.[ch].
2734 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * Added silc_pkcs_decode_identifier to decode the public key's
2737 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2738 Added also silc_pkcs_free_identifier. Added also new context
2739 SilcPublicKeyIdentifier.
2741 * Added -S option to the silc client. It is used to dump the
2742 contents of the specified public key file.
2744 * Changed the PKCS api to return the public key length when
2745 setting the public key.
2747 * Fixed a fatal bug in the public and private key file loading.
2748 Affected file lib/silccrypt/silcpkcs.c.
2750 * Execute the packet parsing for client with zero (0) timeout
2751 if the protocol is active. Affected file silcd/server.c.
2753 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * Made the key generation options to the silcd program. Added
2756 -C option, equivalent to client's option.
2758 * Added new [ServerKeys] config section to the server. It
2759 configures the server's public and private key.
2761 * Defined generic Public Key Payload into the protocol
2762 specification to send specific type of public keys and
2765 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2766 public key or certificate.
2768 * Implemented the GETKEY command to the server and to the
2769 client library and on user interface.
2771 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Made preliminary `make install' work.
2775 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2777 * Added SilcServerRekey context into silcd/idlist.h.
2779 * Added the PFS support as defined in the specification to the
2780 SKE protocol. Affected files lib/silcske/*.c.
2782 * Added `ske_group' field to the SilcServerRekey context to hold
2783 the number of the SKE group that is used with PFS in re-key.
2784 Affected file silcd/idlist.h.
2786 * Added PFS re-key support to the server. Affected file is
2789 * Added silc_protocol_cancel to cancel execution of the next
2790 state of the protocol. Affected file is
2791 lib/silccore/silcprotocol.[ch].
2793 * Added the re-key support with and without PFS to the client
2794 library. Re-key is performed once in an hour, by default.
2796 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2797 Added silc_client_rekey_callback and silc_client_rekey_final.
2798 Affected files are lib/silcclient/protocol.[ch] and
2799 lib/silcclient/client.[ch].
2801 * Removed the `hmac_key' and `hmac_key_len' fields from the
2802 SilcClientConnection structure; not needed. Affected file is
2803 lib/silcclient/client.h.
2807 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Do not ask whether user wants to use the negotiated private key
2810 for private messages, just use it. Affected file is
2811 silc/local_command.c.
2813 * Added `send_enc_key' and `enc_key_len' fields to the
2814 SilcIDListData structure since they are needed in the re-key
2815 phase. Affected file is silcd/idlist.[ch].
2817 * Implemented the simple re-key protocol into the server.
2818 Affected files silcd/server.c and silcd/protocol.[ch]. The
2819 re-key will be performed once in an hour, by default.
2821 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2822 Added silc_server_rekey, silc_server_rekey_callback and
2823 silc_server_rekey_final.
2825 * Removed Tunneled flag from the protocol. Updated the code
2826 and the specifications.
2828 * Adde `pfs' field to the SilcIDListData to indicate whether
2829 the PFS is to be performed in the re-key. Affected file is
2832 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2835 int64 of at least the xintXX size. If void * is less that 4
2836 bytes uint32 * will be used. Defined bool as boolean.
2838 * Changed _ALL_ unsigned long and unsigned int to uint32,
2839 unsgined short to uint16 in the source tree.
2841 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2842 not handle clients that has entry->data.registered == FALSE.
2843 They are not in the network anymore. Affected file is
2846 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Implemented the sending of the SERVER_SIGNOFF notify in the
2849 server. Affected file is silcd/server.c.
2851 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2852 Added also silc_notify_payload_encode_args into the
2853 lib/silccore/silcnotify.[ch].
2855 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2856 Affected file silcd/packet_receive.c.
2858 * Implemented the SERVER_SIGNOFF notify handling in the client
2859 library. Affected file lib/silcclient/client_notify.c. Also,
2860 implemnted the printing of the SERVER_SIGNOFF info to the
2861 application. Affected file silc/client_ops.c.
2863 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2864 if the deleting was successful. Affected file silcd/idlist.[ch].
2866 * Added support for public key authentication in the connection
2867 authentication protocol in the client library. Affected file
2868 lib/silcclient/protocol.c.
2870 * Changed the server's silc_idlist_get_clients_by_* interface
2871 to support already allocated array so that new entries may be
2872 added to pre-allocated array. Affected file silcd/idlist.[ch].
2873 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2874 and command replies.
2876 * All command reply functions in the server now calls the
2877 pending command callback even if error occured. This way the
2878 error will be delivered to the client as well. Affected files
2879 silcd/command.c and silcd/command_reply.c.
2881 * Fixed INFO command to return local server's info if no server
2882 was provided. Affected file lib/silcclient/command.c.
2884 * Removed RESTART command for good. Updated the code and the
2887 * Rewrote parts of the task system. It is a bit simpler now.
2888 Removed unsued task priorities. The affected files are
2889 lib/silcutil/silctask.[ch].
2891 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Moved the USERS printing from the library to the application.
2894 Affected files lib/silcclient/command.c and silc/client_ops.c.
2896 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2900 * Added channel key re-key support. The re-key is perfomed
2901 only by the router and is done once in an hour. Added `rekey'
2902 field to the SilcChannelEntry in the server. Affected files
2903 silcd/server.c and silcd/idlist.h.
2905 * Added silc_task_unregister_by_context into the file
2906 lib/silcutil/silctask.[ch].
2908 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Added SILC_UMODE_GONE mode to indicate when the client is not
2911 present in the SILC network. Added also support to the local
2912 command AWAY that will set this mode. Added support of showing
2913 "xxx is gone" in WHOIS command. The USERS command shows the
2914 gone status as well.
2916 * Fixed setting server and router operator privileges in the
2917 server's UMODE command. Affected file silcd/command.c.
2919 * Merged the SKE KE1 and KE2 payloads into one payload. The
2920 new KE payload is equivalent to the old KE2 payload.
2922 Cleaned up the SKE Start Payload parsing. It now uses the
2923 simple buffer unformatting to do the parsing. A lot faster
2926 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2927 to the SKE that is used to indicate whether both of the SKE
2928 parties should perform authentication. By default only the
2929 responder performs authentication. By setting this flag also
2930 the initiator must do authentication. By default it is unset
2931 since in normal SKE case, client to server connection, only
2932 the responder should do authentication. When doing SKE between
2933 two clients both should perform authentication. Updated the
2934 code and the protocol specs.
2936 * A little fix to IDENTIFY command in the server. Search the
2937 client first by hash not nickname. Affected file is
2940 * Fixed the silc_client_close_connection to support closing
2941 the client to client connections wihtout deleting too much
2942 data. Affected file lib/silcclient/client.c.
2944 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2945 are received if protocol used to be active but is not anymore
2946 the application would crash due to NULL pointer dereference.
2947 Affected files silcd/server.c and lib/silcclient/client.c.
2949 * Added `hash' field to the SilcClientConnection to include
2950 the hash function negotiated in the SKE protocol.
2952 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2953 to set the channel founder authentication data. A client can
2954 claim the founder rights later by providing the authentication
2955 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2956 This way the channel founder can regain the channel founder
2957 privileges even it is left the channel. This works only on
2958 local server and the client must be connected to the same
2959 server to be able to regain the founder rights. Updated the
2960 protocol specs accordingly.
2962 Added support to the CMODE command in the client to set the
2963 founder auth data. Read the README to see how to set it.
2965 Added support to the CUMODE command to claim the founder
2966 rights. Read the README to see how to do it.
2968 Added support for the founder authentication to the Channel
2969 Entry in the server. Affected file silcd/idlist.h.
2971 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2972 server's CMODE command. Affected file silcd/command.c.
2974 * Added the following new functions into lib/silccore/silcauth.[ch]:
2975 silc_auth_get_method and silc_auth_get_data.
2977 * The server now saves the remote hosts public key to the
2978 SilcIDListData pointer. Affected file silcd/protocol.c.
2980 * The normal server now does not remove the channel entry from
2981 the cache if the founder authentication data is set. It used
2982 to remove it if the founder was the last one on the channel on
2983 the server and left the channel. The auth data is saved and
2984 if the channel is re-joined later the old entry is used with
2985 the old auth data. Affected files silcd/command_reply.c and
2988 * Removed the `pkcs' field from the SilcIDListData structure
2989 in the server; it is not used. Affected file silcd/idlist.h.
2991 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2993 * Fixed packet processing on slow links. Partial packets were
2994 never re-processed because the incoming data buffer was cleared
2995 by the application. Application must not directly clear the
2996 sock->inbuf, the packet processing routines handle it. Fixed
2997 this in client library and in server.
2999 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Fixed the WHOIS and IDENTIFY send reply function to really
3002 check whether to send list or just one entry. Affected file
3005 * Cleaned up the LEAVE command's channel key distribution. The
3006 affected file silcd/command.c.
3008 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3009 can enforce the channel mode as well. In that case the ID
3010 includes the ID of the server. The code now enforces the
3011 mode change if the router have different mode than the server.
3013 * The notify client operation with CMODE_CHANGE notify can now
3014 return NULL client_entry pointer if the CMODE was not changed
3015 by client. Application must check for this.
3017 * Added <Server ID> argument to INFO command to support server
3018 info fetching by Server ID.
3020 * Added silc_server_announce_get_channel_users to get assembled
3021 packets of channel users of the specified channel. Affected
3022 file silcd/server.[ch].
3024 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3025 was freed underneath the ID Cache.
3027 * Re-announce clients when the server received CHANNEL_CHANGE
3028 notify from the router. Affected file silcd/packet_send.c.
3030 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3032 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3033 crashed since it did not handle the fact that there is no cipher
3034 called "3" and didn't check the error condition. Now fixed.
3036 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3037 flag. It can be used to send message requests.
3039 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Implemented the RESTART command in the client.
3043 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3044 notice type messages. Added notice printing to the user
3047 * The channel keys are not re-generated if the channel's mode
3048 is PRIVKEY, ie private key on the channel exists. Affected
3049 files silcd/server.c and silcd/command.c.
3051 * Fixed a little bug in channel message delivery when channel
3052 private keys are set in the server. Affected file is
3053 silcd/packet_send.c.
3055 * Changed the setting on channel->on_channel = TRUE from the
3056 silc_client_save_channel_key to the JOIN command reply. The
3057 key payload is not received if the private channel key is set.
3058 Affected file lib/silcclient/command_reply.c and the
3059 lib/silcclient/client_channel.c.
3061 * When the CMODE_CHANGE notify is sent and the channel private
3062 key mode is removed the channel key must be re-generated in
3063 other cells as well. Added this support for the router in the
3064 silcd/packet_receive.c.
3066 * Added new local command NOTICE to send notice message on
3067 channel. Affected file silc/local_command.[ch].
3069 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Added new local command ME to the client. It is used to send
3072 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3073 some action. Affected file silc/local_command.[ch].
3075 * Changed channel_message and private_message client operations
3076 to deliver the message flags to the application. Added also
3077 the `flags' arguments to the silc_client_send_channel_message
3078 and silc_client_send_private_message functions. Affected file
3081 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3083 * Redefined the Private Message Payload to support private message
3084 keys and to support the new private message flags. Updated
3085 the protocol specs. Flags makes it possible to have for example
3086 CTCP style messages.
3088 * Added new type SilcPrivateMessagePayload and defined an API
3089 for it in the lib/silcclient/silcprivate.[ch].
3091 * Tested private message private keys successfully. Tested the
3092 private message key set, unset and list commands with the new
3095 * Redefined the Channel Message Payload to include the channel
3096 message flags (equal with private message flags) to support
3097 for example CTCP style messages.
3099 * Defined some of the message (for channel and private message)
3100 flags. Updated the protocol specs and added the flags to the
3101 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3103 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3105 * Added SilcKeyAgreementStatus type to the key agreement routines
3106 to indicate the current status and error if one occured.
3107 The status types are defined in the lib/silcclient/silcapi.h.
3109 * Added new local command KEY that is used to set and unset private
3110 keys for channels, set and unset private keys for private messages
3111 with remote clients and to send key agreement requests and
3112 negotiate the key agreement protocol with remote client. The
3113 key agreement is supported only to negotiate private message keys,
3114 it currently cannot be used to negotiate private keys for channels,
3115 as it is not convenient for that purpose.
3117 * Fixed a minor pending callback setting bug in the function
3118 silc_client_get_client_by_id_resolve, now the function works.
3119 Affected file lib/silcclient/idlist.c.
3121 * Added function silc_net_get_local_port to get local bound
3122 port by socket. Added to lib/silcutil/silcnet.[ch].
3124 * Added `sockets' and `sockets_count' fields to the SilcClient
3125 object. They hold the sockets of the listenning sockets in
3126 the client. Listenning sockets may be for example the key
3127 agreement server. Affected file lib/silcclient/client.[ch].
3128 Added functions the silc_client_add_socket and the
3129 silc_client_del_socket. They are exported to the application
3132 * Added ~./silc/clientkeys to support other client's public keys.
3134 * Renamed verify_server_key client operation to verify_public_key
3135 and added one argument to indicate the type of the connection
3136 (server, client etc.).
3138 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Added silc_server_connection_auth_request to handle the
3141 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3142 silcd/packet_receive.[ch].
3144 * Added silc_server_send_connection_auth_request into the
3145 silcd/packet_send.c to send the connection auth request packet.
3147 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3150 * Fixed the public key authentication in responder side in the
3151 server. The `auth_data' pointer includes the SilcPublicKey
3152 not the path to the public key. Affected file silcd/protocol.c.
3154 * Implemented the public key authentication in the initiator side
3155 in the server. Affected file silcd/protocol.c.
3157 * Removed the [RedirectClient] config section from the server
3158 configuration. Is not needed and I don't want to implement it.
3160 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Cleaned up the CMODE command in the server. It now works
3163 correctly and supports all the modes defined in the protocol.
3164 Affected file is silcd/command.c.
3166 * Added `hmac_name' field to the SilcChannelEntry in the server
3167 to hold the default HMAC of the channel. It can be set when
3168 creating the channel (with JOIN command). Affected files
3171 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3172 type to indicate the change of the current cipher and hmac
3173 on the channel. Client can safely ignore the <cipher> argument
3174 (if it chooses to do so) since the CHANNEL_KEY packet will
3175 force the channel key change anyway. The <hmac> argument is
3176 important since the client is responsible of setting the new
3177 HMAC and the hmac key into use.
3179 * Fixed the CMODE command in the client library as well.
3181 * Tested CMODE command in router environment successfully.
3183 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3185 * Show the version of the remote client (or server) when connecting
3186 to the server. It is logged to the log file. Affected file
3187 is silcd/protocol.c.
3189 * Fixed the KILLED notify handling in the client library. The
3190 client must be removed from all channels when receiving the
3193 Also, do not remove the client entry when giving the KILL
3194 command but when the KILLED notify is received.
3196 * Removed silc_idlist_find_client_by_nickname from the server.
3197 Not needed anymore. Affected files silcd/idlist.[ch].
3199 * Implemented the CHANNEL_CHANGE notify type handling to the
3200 server. Affected file silcd/server.c.
3204 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added silc_server_send_notify_invite to send the INVITE
3207 notify between routers.
3209 * Implemented the INVITE command correctly to the server.
3211 * Implemented the INVITE notify type handling in the server.
3213 * Implemented the INVITE command to the client library and on the
3216 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3218 * Added function silc_server_get_client_resolve to find the
3219 client entry by ID from all ID lists and then resolve it
3220 (using WHOIS) if it cannot be found. Affected file is
3223 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Implemented the BAN command to the client library.
3227 * The JOIN command in the server now checks the invite list
3230 * Changed the silc_command_reply_payload_encode_va and the
3231 silc_command_payload_encode_va to support that if argument is
3232 NULL it ignores and checks the next argument. Affected file
3233 lib/silccore/silccommand.c.
3235 * Added silc_server_send_notify_ban to send the BAN notify
3236 type between routers.
3238 * Chaned the silc_notify_payload_encode to support that if
3239 argument is NULL it ignores and checks the next argument.
3240 Affected file lib/silccore/silcnotify.c.
3242 * Tested ban lists in router environment successfully.
3244 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Implemented BAN command to the server, in silcd/command.[ch].
3248 * Removed the BAN and INVITE_LIST modes from the CMODE command
3251 * Added function silc_string_match to regex match two strings.
3252 Affected files lib/silcutil/silcutil.[ch].
3254 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Redefined parts of the SilcChannelEntry in the server to support
3257 the new ban and invite lists.
3259 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Redefined the INVITE command. The same command can be used to
3262 invite individuals to the channel but also to manage the invite
3263 list of the channel (to add to and remove from the invite list).
3264 Updated the protocol specs.
3266 * Added new command SILC_COMMAND_BAN that can be used to manage
3267 the ban list of the channel. Updated the protocol specs.
3269 * Removed the channel modes: the SILC_CMODE_BAN and the
3270 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3271 in the CMODE command. The equivalent features are now available
3272 using INVITE and BAN commands. Updated the protocol specs.
3274 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3275 in the network about change in the current ban list. The notify
3276 type is not used by the client.
3278 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3279 support the invite lists.
3281 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Added new function silc_string_regexify that converts string
3284 including wildcard characters into regex string that can
3285 be used by the GNU regex library. Added into the file
3286 lib/silcutil/silcutil.[ch].
3288 Added silc_string_regex_combine to combine to regex strings
3289 into one so that they can be used as one regex string by
3290 the GNU regex library. Added into the file
3291 lib/silcutil/silcutil.[ch].
3293 Added silc_string_regex_match to match two strings. It returns
3294 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3296 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Imported GNU regex to the soruce tree into lib/contrib.
3299 Fixed some compiler warning from the regex.c.
3301 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Fixed MOTD command in the server to work in router environment.
3305 * Fixed the MOTD command in the client library to support
3306 the server argument in the command.
3308 * Added `nickname_len' argument to the silc_idlist_add_client
3309 in the server, as the `nickname' argument may be binary data
3312 * Added silc_idlist_get_channels to return all channels from
3315 * Implemented LIST command to the server. Affected file is
3318 * Implemented the LIST command to the client library and on the
3321 * Added [<user count>] argument to the LIST command reply.
3322 With private channels the user count is not shown.
3324 * Updated TODO and README.
3326 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * The client entry's data.registered must be TRUE even with
3329 global client entry on global client list. The data.registered
3330 is used to check whether the client is anymore in the network,
3331 for example with WHOWAS command so it must be valid.
3333 * Fixed the WHOWAS command in the server. It now actually works
3334 in router environment. Added function into silcd/command_reply.c
3335 silc_server_command_reply_whowas_save.
3337 * Added silc_idlist_purge function to the silcd/idlist.c
3338 to periodically purge the ID Cache.
3340 * Fixed INFO command in the server. It works now in router
3341 environment. Added <server name> argument to the INFO command
3342 reply. Updated the protocol specs.
3344 * Fixed minor bug in silc_idcache_purge to not purge if the
3345 expire value is zero.
3347 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3348 they were buggy because of the WHOWAS information.
3350 * Fixed local command MSG to handle the async resolving of
3351 the remote client properly. It used to fail the first MSG.
3352 Affected file silc/local_command.c.
3354 * Added `data_len' field to SilcIDCache context.
3356 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Update TODO. Todo in commands in the server.
3360 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3363 used by routers as broadcast packet to inform other routers
3364 about the changed user mode.
3366 Implemented the notify handling in the server. Affected file is
3367 silcd/packet_receive.c. Added the function
3368 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3370 * Added new generic Channel Payload and deprecated the New Channel
3371 Payload. The New Channel Payload is now the generic Channel
3374 * Added new argument `mode' to the silc_server_send_new_channel
3375 as it is required in the Channel Payload now.
3377 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3378 and created a new and real SilChannelPayload to represent the
3379 new generic Channel Payload. Implemented the encode/decode
3380 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3382 * Added silc_server_get_client_channel_list to return the list
3383 of channels the client has joined for WHOIS command reply.
3384 Affected file silcd/server.[ch].
3386 * Implemented the channel list sending in the WHOIS command reply
3387 in server and in the client.
3389 Implemented the channel list displaying on the user interface
3390 as well. Affected file silc/client_ops.c.
3392 * Added silc_channel_payload_parse_list to parse list of Channel
3393 Payloads. It returns SilcDList list of SilcChannelPayloads.
3394 Client for example can use this function to parse the list of
3395 channels it receives in the WHOIS command reply. The caller
3396 must free the list by calling silc_channel_payload_list_free.
3397 Affected files lib/silccore/silcchannel.[ch].
3399 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Added one new argument <user mode> to the WHOIS command reply
3402 to return the mode of the user in SILC. Updated the protocol
3405 Implemented it to the server and client.
3407 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3409 * Fixed the mode printing on the user interface on joining.
3410 Affected file silc/client_ops.c.
3412 * Implemented the UMODE command and user modes in general to the
3413 client library and to the user interface.
3415 * Implemented the UMODE command to the server.
3417 * The server now sends UNKNOWN_COMMAND error status if client sends
3418 unknown command. Affected file silcd/command.c.
3420 * All server commands now handle the command identifier the right
3421 way when sending the command reply to the client. The client can
3422 use to identify the command replies with the identifier.
3424 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Added silc_server_get_client_route to resolve the route to
3427 the client indicated by the client ID. Affected file is
3430 * Added silc_server_relay_packet as general function to relay
3431 packet to arbitrary destination. This deprecates functions
3432 like _send_private_message_key, _relay_notify etc. Affected
3433 file is silcd/packet_send.[ch].
3435 Removed silc_server_send_key_agreement,
3436 silc_server_send_private_message_key and
3437 silc_server_packet_relay_notify functions from the file
3438 silcd/packet_send.[ch].
3442 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3443 server. Affected file silcd/packet_receive.[ch].
3445 * Implemented the KILL command to the client. Implemented the
3446 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3447 Affected files lib/silcclient/command[_reply].c and
3448 lib/silcclient/client_notify.c. Implemented the KILL notify
3449 printing in the user inteface.
3451 * Fixed a lot silc_parse_nick memory leaks from the client
3452 library in the file lib/silcclient/command.c.
3454 * Changed the silc_server_send_notify_on_channels's `sender'
3455 argument from SilcSocketConnection to SilcClientEntry to
3456 check the sender as entry and not as connection object and not
3457 to send to the client provided as argument. The affected file
3458 is silcd/packet_send.[ch].
3460 * The notify packets that are destined directly to the client used
3461 to not to be processed by the server. Now changed that and the
3462 server processes all notify packets. After relaying the packet
3463 to the client the notify packet is processed in the server.
3465 * The silc_server_free_client_data now checks whether there is
3466 pending outgoing traffic for the client and purges the data to
3467 the network before removing the client entry.
3469 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3472 an client is killed from the SILC Network. Updated the protocol
3475 Added new function silc_server_send_notify_killed to the
3476 silcd/packet_send.[ch].
3478 * Added function silc_server_packet_relay_notify to relay notify
3479 packets that are destined directly to a client. In this case
3480 the server does not process the notify packets but merely relays
3481 it to the client. Affected file silcd/packet_send.[ch].
3483 Added also silc_server_packet_process_relay_notify to check
3484 whereto relay the notify. Affected file is
3485 silcd/packet_receive.[ch].
3487 * Implemented the KILL command to the server.
3491 * Added the backup schema desgined last fall to the protocol
3492 specs for everyone to see. The specification is in the
3493 *-spec-xx.txt draft and the packet type definitions for the
3494 backup routers is in *-pp-xx.txt draft. Thusly, added also
3495 new packet type SILC_PACKET_CELL_ROUTERS.
3497 * A big security problem in the implementation discovered. The
3498 signoff of an client did not cause new channel key generation
3499 which it of course should've done. The channel keys must be
3500 always re-generated when client leaves (or signoffs) the channel.
3501 The silc_server_remove_from_channels funtion now handles
3502 the channel key re-generation.
3504 * Added `sender' argument to the silc_server_send_notify_on_channels
3505 to not to send the client provided as argument. Affected file
3506 silcd/packet_send.[ch].
3508 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Implemented OPER and SILCOPER commands into the server and
3513 * Added silc_auth_verify and silc_auth_verify_data to verify
3514 the authentication directly from the authentication payload.
3515 It supports verifying both passphrase and public key based
3516 authentication. Affected file lib/silccore/silcauth.[ch].
3518 * Added `hash' field to the SilcIDListData structure. It is the
3519 hash negotiated in the SKE protocol. Affected file is
3522 * Slight redesigning of the SilcAuthPayload handling routines.
3523 Do not send SilcPKCS but SilcPublicKey as argument.
3525 * Implemented the public key authentication support to the
3526 serverconfig. The public key is loaded from the provided path
3527 and saved as authentication data to void * pointer. Thus,
3528 changed the unsigned char *auth_data to void *auth_data;
3530 * Fixed SHUTDOWN command to send the reply before the server
3531 is shutdown. :) Affected file silcd/command.c.
3533 * Fixed fatal bug in CONNECT command. The hostname was invalid
3534 memory and server crashed. Affected file silcd/command.c.
3536 * Fixed fatal bug in CLOSE command. The server_entry became
3537 invalid but was referenced later in the command. Affected file
3540 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3542 * Fixed fatal bug in failure packet handling. Server ignored
3543 the failure and thus crashed when it came.
3547 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3549 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3550 that the command may be executed only once in (about) 2 seconds.
3551 The old SILC_CF_LAG flag is same but allows command bursts up
3552 to five before limiting.
3554 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3555 server code. Various commands now includes the CF_LAG_STRICT
3556 flag to disallow any kind of miss-use of the command.
3558 * Fixed the silc_buffer_unformat to not to allocate any data
3559 if the length of the data is zero. It used to allocate the
3560 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3562 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Changed the format of AdminConnection configuration section
3565 in the server. Added username of the admin to the format.
3566 Affected files silcd/serverconfig.[ch].
3568 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3569 to return admin configuration data by host, username and/or
3572 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Implemented WHOWAS command to the server. Added the functions:
3576 silc_server_command_whowas_parse,
3577 silc_server_command_whowas_send_reply,
3578 silc_server_command_whowas_from_client and
3579 silc_server_command_whowas_from_server
3581 * Added <Client ID> argument to the WHOWAS command reply. Updated
3582 the protocol specs accordingly.
3584 * Implemented WHOWAS command and command_reply to the client
3587 Implemented the WHOWAS printing on the user interface.
3589 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Added new argument to the WHOWAS command reply, the real name.
3592 It is an optional argument. Updated the protocol specs.
3594 * Added SilcIDCacheDestructor callback that is registered when
3595 the SilcIDCache is allocated. The callback is called when
3596 an cache entry in the ID Cache expires, or is purged from the
3597 cache. Added into lib/silccore/idcache.[ch].
3599 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3600 to destruct the client entries when the cache entry expires.
3601 Other ID Cache's in server and in the client library ignores
3604 * If the ID Cache entry's `expire' field is zero then the entry
3605 never expires. Added boolean `expire' argument to the
3606 silc_idcache_add function in the lib/silccore/idcache.[ch].
3607 If it is TRUE the default expiry value is used.
3609 * Added silc_server_free_client_data_timeout that is registered
3610 when client disconnects. By default for 5 minutes we preserve
3611 the client entry for history - for WHOWAS command.
3613 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3615 * Added support to the server to enforce that commands are not
3616 executed more than once in 2 seconds. If server receives
3617 commands from client more frequently, timeout is registered
3618 to process the commands. Affected file silcd/command.c.
3619 Added new function silc_server_command_process_timeout.
3621 * Changed NICK_NOTIFY handling in client library to check that
3622 if the client's nickname was changed, so there is no need to
3623 resolve anything from the server.
3625 * Removed error printing from the WHOIS and IDENTIFY commands.
3626 If error occurs then it is ignored silently in the client library.
3627 The application, however, may map the received error to
3628 human readable error string. The application currently maps
3629 the NO_SUCH_NICKNAME error to string.
3631 * Made the command status message public to the application. Moved
3632 them from lib/silcclient/command_reply.c to
3633 lib/silcclient/command_reply.h. The application can map the
3634 received command status to the string with the
3635 silc_client_command_status_message function.
3637 * Added check to the server to check that client's ID is same
3638 as the Source ID in the packet the client sent. They must
3641 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * Added dist-bzip hook to the Makefile.am to make bzip2
3644 compressed distributions.
3646 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Server now enforces the maximum length for the nickname and
3649 the channel as protocol specification dictates. 128 bytes for
3650 nickname and 256 bytes for channel name.
3652 * Moved the WHOIS printing to the application. The client libary
3653 does not print out the WHOIS information anymore, the application
3654 must do it. Renamed silc_client_command_reply_whois_print to
3655 the silc_client_command_reply_whois_save.
3657 The client's idle time is also sent to the application now, and
3658 the idle is shown on screen.
3660 * Added silc_client_command_reply_identify_save to save the
3661 received IDENTIFY entries.
3663 * Do not check for channel private keys in message sending and
3664 reception if the channel does not have the PRIVKEY mode set.
3665 Affected file lib/silclient/client_channel.c.
3667 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3670 just surfaced after chaning the JOIN procedure.
3672 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3674 * Added silc_client_get_clients_by_list to get client entries
3675 from Client ID list, that is returned for example by JOIN
3676 and USERS command replies. The application should use this
3677 function for example when JOIN command reply is received to
3678 resolve the clients already on the channel (library does not
3679 do that anymore as USERS command reply is not used in the JOIN
3680 procedure anymore). Affected files lib/silcclient/silcapi.h and
3681 lib/silcclient/idlist.c.
3683 * JOIN command reply and USERS command reply returns now SilcBuffer
3684 pointers instead of unsigned char pointers when returning
3685 the client list and mode list.
3687 * Added <Client ID> argument to the JOIN command reply, mainly
3688 for the server to identify for which client the command was
3689 originally sent. Updated protocol specs accordingly.
3691 * Added SilcDlist private_key pointer to the SilcChannelEntry
3692 in the client to support the channel private keys. Affected
3693 file is lib/silcclient/idlist.h.
3695 * Added SilcChannelPrivateKey argument to the function
3696 silc_client_send_channel_message so that application can choose
3697 to use specific private ke if it wants to. If it is not provided,
3698 the normal channel key is used, unless private keys are set.
3699 In this case the first (key that was added first) is used
3700 as the encryption key.
3702 * Implemented the support for channel private key handling.
3703 Implemented the following functions:
3705 silc_client_add_channel_private_key,
3706 silc_client_del_channel_private_keys,
3707 silc_client_del_channel_private_key,
3708 silc_client_list_channel_private_keys and
3709 silc_client_free_channel_private_keys
3711 Affected file lib/silcclient/client_channel.c.
3713 * Added the support for the private keys in the channel message
3714 sending and encryption and in the message reception and
3715 decryption. Affected funtions are
3716 silc_client_send_channel_message and silc_client_channel_message.
3718 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Added SKE's key verify callback to the client library's
3721 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3723 * Removed the statement that server (or router) must send USERS
3724 command reply when joining to the channel so that the client
3725 knows who are on the channel. Instead, the client list and
3726 client's mode list is now sent in the JOIN command reply to the
3727 client who joined channel. This is better solution.
3729 * Added function silc_server_get_users_on_channel and function
3730 silc_server_save_users_on_channel to the silcd/server.[ch].
3732 * Removed function silc_server_command_send_users from the
3735 * Do not show topic on the client library anymore. The topic is
3736 sent in the command reply notify to the application and the
3737 application must show the topic now.
3739 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3741 * Added client searching by nickname hash into the IDENTIFY and
3742 WHOIS commands in the server as they were clearly missing from
3743 them. Affected file is silcd/command.c.
3745 * Fixed a bug in private message receiving in the client library.
3746 The remote ID was freed and it wasn't supposed, now it is
3749 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Minor fix to the channel payload; allocate the data area, as it
3752 needs to be of specific length.
3754 * If the key agreement port is zero then the operating
3755 system will define the bound port. Affected files are
3756 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3758 * Added new function silc_channel_payload_decrypt into the file
3759 lib/silccore/silcchannel.[ch].
3761 * Moved the channel message etc, check from silc_packet_decrypt
3762 to applications. The library calls now a generic
3763 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3764 when the packet is either normal or special. This was done to
3765 allow more wide range of checking that was not allowed when
3766 the code was in library. Now applications can do virtually any
3767 checks to the packet and return to the library the decision how
3768 the packet should be processed. Affected files are
3769 lib/silccore/silcpacket.[ch].
3771 Added silc_server_packet_decrypt_check to the server and
3772 silc_client_packet_decrypt_check to the client library.
3774 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3775 to send with specified source and destination information.
3777 * Channel message delivery between routers was broken after the
3778 channel key distribution was fixed earlier. The channel key
3779 was used be to distributed to other routers as well which is not
3780 allowed by the protocol. Now this is fixed and channel keys
3781 really are cell specific and the channel message delivery between
3782 routers comply with the protocol specification.
3784 * Fixed various commands in server to check also the global list
3785 for the channel entry and not just the local list. The affected
3786 file silcd/command.c.
3788 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3790 * Added assert()s to buffer formatting and unformatting routines
3791 to assert (if --enable-debug) when error occurs. Affected
3792 file: lib/silcutil/silcbuffmt.c.
3794 * Changed to auto-reconnect to check whether the remote host is
3795 router and register the re-connect timeout if it is. It used
3796 to check that whether we are normal server, but router must do
3797 auto-reconnect with another router as well. Affected file
3800 * Removed the [<key len>] option from CMODE command as the cipher
3801 name decides the key length, nowadays. See the defined ciphers
3802 from the protocol specification.
3804 * Added [<hmac>] option to the CMODE command to define the HMAC
3805 for the channel. Added SILC_CMODE_HMAC channel mode.
3807 * Added [<hmac>] option for the JOIN command so that user can
3808 select which HMAC is used to compute the MACs of the channel
3811 * Added Hmac field to the Channel Message Payload. The integrity
3812 of plaintext channel messages are now protected by computing
3813 MAC of the message and attaching the MAC to the payload. The
3814 MAC is encrypted. Now, it is clear that this causes some
3815 overhead to the size of the packet but rationale for this is that
3816 now the receiver can verify whether the channel message decrypted
3817 correctly and also when private keys are set for the channel the
3818 receiver can decrypt the packet with several keys and check from
3819 the MAC which key decrypted the message correctly.
3821 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3822 lib/silccrypt/silccipher.[ch].
3824 * Added silc_hash_len to return the digest length into the
3825 lib/silcrypt/silchash.[ch].
3827 * Rewrote parts of Silc Channel Payload interface in the
3828 lib/silccore/silcchannel.[ch]. The encode function now also
3829 encrypts the packet and parse function decrypts it.
3831 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3833 * Fixed a minor formatting bug in the SKE's key material processing.
3834 It actually might have processed the keys wrong way resulting
3837 * Redefined the mandatory HMAC algorithms and added new algorithms.
3838 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3839 and hmac-md5 truncated to 96 bits. The mandatory is now
3840 hmac-sha1-96. Rest are optional (including the one that used
3841 to be mandatory). Rationale for this is that the truncated HMAC
3842 length is sufficient from security point of view and can actually
3843 make the attack against the HMAC harder. Also, the truncated
3844 HMAC causes less overhead to the packets. See the RFC2104 for
3847 * Added new [hmac] configuration section. The SKE used to use
3848 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3849 is of course wrong. The official names that must be proposed in
3850 the SKE are the ones defined in the protocol specification
3851 (hmac-sha1-96 for example). The user can configure any hmac
3852 using any hash function configured in the [hash] section. At
3853 least, the mandatory must be configured.
3855 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3857 * Added HMAC list to the SKE proposal list. It has now both
3858 hash algorithm list and HMAC list. This makes the protocol
3859 incompatible with previous versions. The SKE now seems to work
3860 the way it is supposed to work, for the first time actually.
3862 * Defined plain Hash algorithms to the protocol specification.
3865 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Implemented support for key agreement packets into the server.
3868 Added functions silc_server_key_agreement and
3869 silc_server_send_key_agreement. Other than these functions,
3870 server has nothing to do with this packet.
3872 * Added support for private message key packets into the server.
3873 Added functions silc_server_private_message_key and
3874 silc_server_send_private_message_key.
3878 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3879 called in the protocol's final callback instead in the END
3880 protocol state. This makes a little more sense and in the same
3881 time in client we can use the same protocol routines for normal
3882 key exchange and to key agreement packet handling as well.
3884 * Added to both client's and server's KE protocol context the
3885 SilcSKEKeyMaterial pointer to save the key material. We will
3886 bring the key material to the protocol's final callback by doing
3887 this. The final callback must free the key material.
3889 * Added SKE's packet_send callback into client's KE protocol
3890 context so that the caller can choose what packet sending function
3891 is used. This way we can use different packet sending when
3892 doing normal SKE when doing key agreement packet handling (in
3893 the key agreement packet handling we do not want to encrypt
3896 * Implemented the responder side of the key agreement routines
3897 in the client. The client can now bind to specified port and
3898 accept incoming key negotiation. The key material is passed
3899 to the application after the protocol is over.
3901 * Implemented the processing of incoming Key Agreement packet
3902 in the client. Added function silc_client_key_agreement to
3905 * Implemented the intiator side of the key agreement routines
3906 in the client. The client can now initiate key agreement with
3907 another remote client. The key material is passed to the
3908 application after the protocol is over.
3910 * Created client_keyagr.c to include all the key agreement
3913 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3914 SILC_TASK_CALLBACK except that it is not static.
3916 * Created client_notify.c and moved the Notify packet handling
3917 from the client.[ch] into that file.
3919 * Created client_prvmsg.c and moved all private message and
3920 private message key routines from the client.[ch] into that file.
3922 * Create client_channel.c and moved all channel message and
3923 channel private key routines from the client.[ch] into that file.
3925 * Changed silc_client_get_client_by_id_resolve to resolve with
3926 WHOIS command instead of IDENTIFY command, in the file
3927 lib/silclient/idlist.c.
3929 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3931 * Implemented the SKE's responder side to the Client library.
3933 * When FAILURE is received to the protocol do not trust it
3934 blindly. Register a timeout to wait whether the remote closes
3935 the connection as it should do it, only after that process the
3936 actual failure. This was changed to both client and server.
3938 * Added client_internal.h to include some of the structures
3939 there instead of client.h in lib/silcclient/.
3941 * Added function silc_task_unregister_by_callback to unregister
3942 timeouts by the callback function.
3944 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * Some "Incomplete WHOIS info" errors has been appearing on the
3947 log files. Took away the entry->userinfo check from WHOIS
3948 reply sending. The entry->userinfo is now " " if client did not
3949 provide one. I thought this was fixed earlier but something
3950 is wrong still. Let's see if the error still appears.
3952 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Fixed a minor bug in the login when the channel key is
3955 re-generated in the server. It used to generate the key in
3956 wrong order and thus caused problems in the channel traffic.
3958 * Fixed a minor bug in channel key distsribution after
3959 KICK command. The key was not sent to the router even though
3962 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Added silc_ske_process_key_material_data as generic routine
3965 to process any key material as the SILC protocol dictates. The
3966 function is used by the actual SKE library but can be used by
3967 applications as well. This relates to the private message keys
3968 and the channel private keys since they must be processed the
3969 same way the normal SILC session keys. The protocol dictates
3970 this. Affected files: lib/silcske/silcske.[ch].
3972 Added also silc_ske_free_key_material to free the
3973 SilcSKEKeyMaterial structure.
3975 * Defined silc_cipher_set_key function to set the key for
3976 cipher without using the object's method function. The affected
3977 files: lib/silccrypt/silccipher.[ch].
3979 * Implemented silc silc_client_add_private_message_key,
3980 silc_client_add_private_message_key_ske,
3981 silc_client_del_private_message_key,
3982 silc_client_list_private_message_keys and
3983 silc_client_free_private_message_keys functions in the
3986 Added functions silc_client_send_private_message_key to send
3987 the Private Message Key payload and silc_client_private_message_key
3988 to handle incoming Private Message Key payload.
3990 * Added Cipher field to the Private Message Key payload to set
3991 the cipher to be used. If ignored, the default cipher defined
3992 in the SILC protocol (aes-256-cbc) is used.
3994 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Removed lib/silcclient/ops.h file.
3998 Redefined parts of the SILC Client Library API. Created new
3999 file silcapi.h that deprecates the ops.h file and defines the
4000 published Client Library API. Defined also private message key
4001 API and channel private key API into the file.
4003 This is the file that the application must include from the
4004 SILC Client Library. Other files need not be included by
4005 the application anymore.
4007 * Added new key_agreement client operation callback and also
4008 defined the Key Agreement library API for the application.
4010 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4012 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4013 is used by clients to request key negotiation between another
4014 client in the SILC network. If the negotiation is started it
4015 is performed using the SKE protocol. The result of the
4016 negotiation, the secret key material, can be used for example
4017 as private message key.
4019 Implemented the Key Agreement payload into the files
4020 lib/silccore/silauth.[ch].
4022 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Redefined ciphers for the SILC protocol. Added some new ciphers
4025 and defined the key lengths for the algorithms. Changed the
4026 code accordingly. The default key length is now 256 bits.
4028 * Fixed SKE key distribution function silc_ske_process_key_material
4029 when the key length is more than 128 bits. The default key
4030 length in SILC is now 256 bits.
4032 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4033 to indicate unsupported algorithm.
4035 * Renamed rijndael.c to aes.c and all functions as well.
4037 * Fixed a long standing channel key setting bug in client library.
4038 Weird that it has never surfaced before.
4040 * Fixed bug in channel deletion. If the entire channel is removed
4041 then it must also delete the references of the channel entry
4042 from the client's channel list as the client's channel entry and
4043 the channel's client entry share same memory.
4045 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * Implemented CONNECT and SHUTDOWN commands in the client.
4049 * Implemented CLOSE command to the client.
4051 * Added the function silc_idlist_find_server_by_name into the
4052 files silcd/idlist.[ch].
4054 Added the function silc_idlist_find_server_by_conn into the
4055 files silcd/idlist.[ch].
4057 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * DIE command was renamed to SHUTDOWN. Updated the both code
4062 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4063 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4065 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4068 * Added function silc_server_create_connection function to create
4069 connection to remote router. My server implementation actually
4070 does not allow router to connect to normal server (it expects
4071 that normal server always initiates the connection to the router)
4072 so the CONNECT command is only good for connecting to another
4075 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4078 or some other client was kicked from the channel.
4080 Implemented the handling of the notify type to both client
4083 Implemented silc_server_send_notify_kicked to send the KICKED
4084 notify. It is used to send it to the server's primary router.
4086 * Implemented the KICK command into server and client.
4088 * Added `query' argument to the silc_idlist_get_client function
4089 to indicate whether to query the client from server or not if
4092 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4093 to indicate that the client is not channel founder.
4097 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Removed the rng context from SilcPacketContext structure and
4100 changed that the packet routine uses the Global RNG API.
4102 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added support for quit message that client can "leave" on the
4105 channel when it quits the SILC. It is ditributed inside the
4106 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4108 Added silc_server_free_client_data that will take the
4109 signoff message as argument.
4111 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4113 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Updated parts of the protocol specification to keep it up
4118 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4121 payloads in one packet.
4123 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4124 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4125 use now the new List flag.
4127 * Also deprecated the following packet types: REPLACE_ID,
4128 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4130 * Added list support for Notify packet in server.
4132 * Added silc_server_send_notify_channel_change to send the
4133 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4134 the silc_server_send_replace_id.
4136 * Added silc_server_send_notify_nick_change to send the
4137 NICK_CHANGE notify type. Deprecates the function
4138 silc_server_send_replace_id.
4140 * Added silc_server_send_notify_join to send the JOIN notify type.
4141 Deprecates the function silc_server_send_new_channel_user.
4143 * Added silc_server_send_notify_leave to send LEAVE notify type.
4144 Deprecates the function silc_server_send_remove_channel_user.
4146 * Added silc_server_send_notify_cmode and
4147 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4148 types. Deprecates the silc_server_send_set_mode function.
4150 * Added SERVER_SIGNOFF notify type to indicate that server has
4151 quit. This means that all clients on the channel from that
4152 server will drop. This can be also used when netsplit happens.
4154 Deprecated REMOVE_ID packet type since it is not needed anymore
4157 Added silc_server_send_notify_server_signoff to send the
4158 SERVER_SIGNOFF notify type. Deprecates the function
4159 silc_server_send_remove_id.
4161 Added also silc_server_send_notify_signoff to send the
4162 SIGNOFF notify type.
4164 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4165 SILC protocol from this day on. Changed the protocol
4166 specification as well.
4168 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4169 notify type. It is used between routers to notify about
4170 topic changes on a channel.
4172 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4175 * Partly updated the protocol specification to comply with the
4176 changes now made. It is still though a bit outdated.
4178 * The JOIN notify type now takes one extra argument <Channel ID>.
4179 The packet used to be destined to the channel but now the
4180 JOIN type may be sent as list thus it is impossible to
4181 destine it to any specific channel. By adding this argument
4182 it is again possible.
4184 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added CREDITS file. The CHANGES and CREDITS file will appear
4187 in the distribution as well.
4189 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4192 types in the server's silcd/packet_receive.c.
4194 * Implemented CMODE and CUMODE to work in router environment.
4196 * Fixed minor encoding and decoding buglet from the
4197 lib/silccore/silcmode.c.
4199 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4202 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4204 * Changed all SilcConfigServer* and silc_config_server* to
4205 SilcServerConfig* and silc_server_config*, respectively.
4208 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4210 * Associated the ID (client or server ID) to the Authentication
4211 Payload to avoid any possibility of forging. Updated the
4212 protocol specification and the code accordingly.
4214 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * The RSA key length is now save to the RsaKey context in the
4217 key generation process in lib/silccrypt/rsa.c. The key length
4218 is now used to figure out the maximum size of the block allowed
4219 to be encrypted/signed.
4221 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4222 is equivalent to the silc_mp_mp2bin but does not allocate any
4225 * Changed silc_mp_mp2bin API to take length argument. If it is
4226 non-zero then the buffer is allocated that large. If zero, then
4227 the size is approximated using silc_mp_sizeinbase, which however
4230 * Created Global RNG API which is global RNG that application can
4231 initialize. After initializing, any routine anywhere in the
4232 code (including library) can use RNG without allocating a new
4233 RNG object. This was done to allow this sort of use of the
4234 RNG in code that has no chance to allocate RNG object. All
4235 applications currently allocate this and many routines in the
4236 library use this. Affected file lib/silccrypt/silcrng.[ch].
4238 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4239 it to use the Global RNG API.
4241 * Defined Authentication Payload into protocol specification that
4242 is used during SILC session to authenticate entities. It is
4243 used for example by client to authenticate itself to the server
4244 to obtain server operator privileges.
4246 Implemented this payload into the lib/silccore/silcauth.[ch].
4247 Implemented also routines for public key based authentication
4248 as the new protocol specification dictates.
4250 Moved definitions of different authentication methods from
4251 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4253 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4254 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4255 silc_pkcs_verify_with_hash functions into the file
4256 lib/silccrypt/silcpkcs.[ch].
4258 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * The client entry's userinfo pointer must be always valid.
4261 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4262 will fail since it requires the userinfo. Now, the userinfo
4263 is allocated as "" if actual userinfo does not exist. Actually,
4264 it must exist and it is totally Ok to drop client connections
4265 that does not announce the userinfo. However, we will make
4266 this workaround for now.
4268 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4269 to return the remote port by socket.
4271 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4274 SILC_SERVER_PENDING_EXEC and added an new macro
4275 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4276 data or when error occurs while processing the pending command.
4278 Added new argument `destructor' into silc_server_command_pending
4279 and to the SilcServerCommandPending object. This destructor is
4280 now called after calling the pending callback or if error occurs
4281 immediately. If error occurs the actual pending callback won't
4282 be called at all - only the destructor. The destructor may be
4283 NULL if destructor is not needed.
4285 All this applies for client library code as well. Similar
4286 changes were made there as well for the pending commands.
4288 In the client, the application must now allocate the
4289 SilcClientCommandContext with the silc_client_command_alloc
4292 * Added reference counter to the SilcServerCommandContext. Added
4293 function silc_server_command_alloc and silc_server_command_dup
4296 Same type of functions added to the client library for the same
4299 * Removed the cmd_ident from IDListData away since it is now
4300 global for all connections. It is the command identifier used
4301 in command sending and with pending commands. The affected file
4304 * Added reference counter to the SilcSocketConnection objecet to
4305 indicate the usage count of the object. The object won't be
4306 freed untill the reference counter hits zero. Currently only
4307 server uses this, and client ignores it. The client must be
4308 set to use this too later. The affected files are
4309 lib/silccore/silcsockconn.[ch]. Added also the function
4310 silc_socket_dup to increase the reference counter.
4312 This was mainly added because it is possible that the socket
4313 is removed underneath of pending command or other async
4314 operation. Now it won't be free'd and proper DISCONNECTING
4315 flags, etc. can be set to avoid sending data to connection that
4316 is not valid anymore.
4318 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4319 the connection. After that it sets SILC_SET_DISCONNECTED.
4320 It is, however, possible that the socket data is not still freed.
4321 The silc_server_packet_process now checks that data is not
4322 read or written to connection that is DISCONNECTED. The socket
4323 get's freed when the reference counter hits zero.
4325 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Changed the client operation API: channel_message operation's
4328 `sender' is now the client entry of the sender, not the nickname
4329 and the `channel' is the channel entry, not the channel name.
4331 In the private_message operation the `sender' is now also the
4332 client entry of the sender not the nickname.
4334 Affected file is lib/silcclient/ops.h and all applications
4335 using the client operations.
4337 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Moved the calling of ops->connect() from connect_to_server_final
4340 into receive_new_id functin since that is the point when the
4341 client is actually allowed to send traffic to network. The
4342 affected file is lib/silcclient/client.c.
4344 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4347 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4348 (if needs broadcasting) instead of broadcasting the packets one
4349 by one which would make a burst in the network traffic.
4351 * Added `broadcast' argument to the functions in silcd/server.[ch]
4352 silc_server_create_new_channel[_with_id] to indicate whether
4353 to send New Channel packet to primary router.
4355 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Added new function into the silcd/server.[ch] files:
4358 silc_server_create_new_channel_with_id to create new channel with
4359 already existing Channel ID.
4361 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4362 lib/silccore/silcpacket.h. This packet is used t send list of
4363 Set Mode payloads inside one packet. Server uses this to set
4364 the modes for the channels and clients on those channels, that it
4365 announced to the router when it connected to it. The protocol
4366 specification has been updated accordingly.
4368 * The silc_server_new_channel did not handle the packet coming
4369 from normal server as it normally does not send that. However,
4370 when it announces its channels it does send it. Implemented
4371 the support for that.
4373 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4374 into the file lib/silccore/id.h.
4376 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4378 * Fixed memory leaks in the functions silc_idlist_del_client,
4379 silc_idlist_del_channel and silc_idlist_del_server in the file
4380 silcd/idlist.c. All of those leaked like a sieve.
4382 * Fixed some small memory leaks in the client's function
4383 silc_client_notify_by_server.
4385 * Added functions into silcd/server.c: silc_server_announce_clients,
4386 silc_server_announce_channels and silc_server_announce_server.
4387 These functions are used by normal and router server to announce
4388 to its primary router about clients, channels and servers (when
4389 router) that we own. This is done after we've connected to the
4392 These functions effectively implements the following packet types:
4393 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4394 and SILC_PACKET_NEW_ID_LIST.
4396 * Added new functions into the silcd/packet_receive.[ch]:
4397 silc_server_new_id_list, silc_server_new_channel_list and
4398 silc_server_new_channel_user_list to handle the incoming
4399 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4401 * Added support of changing Channel ID in the function
4402 silc_server_replace_id. If the server that announces a channel
4403 to the router already exists in the router (with same name but
4404 with different Channel ID), router is responsible to send
4405 Replace ID packet to the server and force the server to change
4406 the Channel ID to the one router has.
4408 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4409 client that the Channel ID has been changed by the router. The
4410 normal server sends this to the client. Client must start using
4411 the new Channel ID as the channel's ID.
4413 Implemented handling of this new type into lib/silcclient/client.c
4414 into the function silc_client_notify_by_server.
4416 * Added new function silc_idlist_replace_channel_id into the files
4417 silcd/idlist.[ch] to replace the Channel ID.
4419 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Call silc_server_command_identify_check always when processing
4422 the IDENTIFY command in silcd/command.c
4424 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4427 send keepalive packets. The packet can be sent by clients,
4428 servers and routers.
4430 Added function silc_socket_set_heartbeat into the file
4431 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4432 If not set, the heartbeat is not performed. The actual
4433 heartbeat is implemented in the low level socket connection
4434 library. However, application is responsible of actually
4437 Added silc_server_send_heartbeat to send the actual heartbeat
4438 packet into silcd/packet_send.[ch]. Server now performs
4439 keepalive with all connections.
4441 * Added silc_task_get_first function into lib/silcutil/silctask.c
4442 to return the timeout task with shortest timeout. There was a bug
4443 in task unregistration that caused problems. TODO has been
4444 updated to include that task system must be rewritten.
4446 * The client library will now resolve the client information when
4447 receiving JOIN notify from server for client that we know but
4448 have incomplete information.
4450 * Rewrote parts of silc_server_remove_from_channels and
4451 silc_server_remove_from_one_channel as they did not remove the
4452 channel in some circumstances even though they should've.
4454 * Encryption problem encountered in server:
4456 The LEAVE command used to send the Channel Key packet to the
4457 router immediately after generating it. However, the code
4458 had earlier sent Remove Channel user packet but not immediately,
4459 ie. it was put to queue. The order of packets in the router
4460 was that Channel Key packet was first and Remove Channel User
4461 packet was second, even though they were encrypted in the
4462 reverse order. For this reason, MAC check failed. Now, this
4463 is fixed by not sending the Channel Key packet immediately but
4464 putting it to queue. However, this is more fundamental problem:
4465 packets that are in queue should actually not be encrypted
4466 because packets that are sent immediately gets encrypted
4467 actually with wrong IV (and thus MAC check fails). So, packets
4468 that are in queue should be encrypted when they are sent to
4469 the wire and not when they put to the queue.
4471 However, the problem is that the current system has not been
4472 designed to work that way. Instead, the packet is encrypted
4473 as soon as possible and left to the queue. The queue is then
4474 just purged into wire. There won't be any fixes for this
4475 any time soon. So, the current semantic for packet sending
4478 o If you send packet to remote host and do not force the send
4479 (the packet will be in queue) then all subsequent packets to the
4480 same remote host must also be put to the queue. Only after the
4481 queue has been purged is it safe again to force the packet
4484 o If you send all packets immediately then it safe to send
4485 any of subsequent packets through the queue, however, after
4486 the first packet is put to queue then any subsequent packets
4487 must also be put to the queue.
4489 Follow these rules and everything works fine.
4491 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Added new function silc_server_remove_clients_by_server to
4494 remove all client entries from ID list when the server connection
4495 is lost. In this case it is also important to invalidate all
4496 client entires as they hold the invalid server entry. This
4497 fixes fatal bug when server has lost connection and will reconnect
4500 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Made some sanity checks to silc_server_daemonise like to check
4503 whether the requested user and group actually exists.
4505 * Added sanity check to SKE's silc_ske_responder_finish to check
4506 that the public and private key actually is valid.
4508 * Invalidate the client's nickname when receiving Replace ID
4509 packet and the Client ID is being replaced. This means that the
4510 server will query the nickname if someone needs it (client)
4513 * Sort the ID Cache in client library when the ID Cache data
4514 has changed (needs sorting).
4516 * Do not allow for SILC client to create several connections to
4517 several servers. The client does not support windows right now
4518 and generating multiple connections causes weird behaviour.
4520 Irssi-silc client does support windows and can handle several
4521 connections without problems, see: www.irssi.org and SILC plugin.
4523 * Fixed some places where client was added to the IDList. The
4524 rule of thumb is following (in order to get everything right):
4525 If the client is directly connected local client then the
4526 `connection' argument must be set and `router' argument must be
4527 NULL to silc_idlist_add_client function. If the client is not
4528 directly connected client then the `router' argument must
4529 bet set and the `connection' argument must be NULL to the
4530 silc_idlist_add_client function.
4532 * The funtion silc_server_packet_send_local_channel actually did
4533 not check whether the client was locally connected or not. It
4534 does that now. Fixed a bug related to LEAVE command.
4536 * Fixed Remove Channel User payload parsing bug in server's
4537 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4539 * The server's silc_server_save_channel_key now checks also the
4540 global ID list for the channel as it might not be in the local
4541 list. Fixed a bug related to LEAVE command.
4543 * Is this the end of the [<unknown>] buglet that has been lurking
4544 around for a long time? A little for loop fix in server's
4545 silc_server_command_whois_parse that is used by both IDENTIFY
4546 and WHOIS command. At least, this was a clear bug and a cause
4547 of one type of [<unknown>] buglet.
4549 * WHOIS and IDENTIFY commands call the function
4550 silc_server_command_[whois/identify]_check function even if
4551 we are not router server.
4553 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * Added --with-gmp configuration option. If set the GMP
4556 is always compiled in the SILC source tree. If not set then
4557 it is checked whether the system has the GMP3 installed. If
4558 it has then the GMP won't be compiled (the system's headers
4559 and library is used), if it doesn't have it then the GMP is
4560 compiled in the SILC source tree.
4562 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Changed RSA private exponent generation to what PKCS #1
4565 suggests. We try to find the smallest possible d by doing
4566 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4567 not security fix but optimization.
4569 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Added new config entry [Identity] to fork the server and run
4572 it as specific user and group. A patch from Bostik.
4574 * Imported Dotconf configuration library into lib/dotconf.
4575 This will be used to create the SILC configuration files later.
4576 It will appear in the distsribution after this commit.
4578 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * A big code auditing weekend happening. Auditing code for
4581 obvious mistakes, bugs and errors. Also, removing any code
4584 Removed files for being obsolete:
4586 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4587 inline in the file lib/silcutil/silcbuffer.h)
4589 o lib/silcutil/silcbufutil.c (the header has inline versions)
4591 Changed code to fix possible error conditions:
4593 o The buffer formatting routines now check that the destination
4594 buffer really has enough space to add the data. This applies for
4595 both buffer formatting and unformatting
4596 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4597 unformatting was changed to accomodate following rules:
4598 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4599 sent to the function while XXX_*STRING will not allocate or copy
4600 the data into the buffer. Instead it sets the pointer from the
4601 buffer into the pointer sent as argument (XXX_*STRING used to
4602 require that the pointer must be allocated already). This change
4603 makes this whole thing a bit more consistent and more optimized
4604 (note that the data returned in the unformatting with XXX_*STRING
4605 must not be freed now). The routines return now -1 on error.
4607 o Tried to find all code that use buffer_format and buffer_unformat
4608 and added return value checking to prevent formatting and
4609 especially unformatting errors and possible subsequent fatal
4612 o Changed ske->x and ske->KEY to mallocated pointers in
4613 lib/silcske/silcske.h. Fixed possible data and memory leak.
4615 o Added return value checking to all *_parse* functions. Fixed
4616 many memory leaks as well.
4618 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4619 so that buffer overflows would not happen. All code now also
4620 checks the return value as it can fail.
4622 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Added reconnection support to server if the normal server looses
4625 its connection to the router (for example if router is rebooted).
4626 The server performs normal reconnection strategy implemented
4627 to the server. Affected file silcd/server.c.
4629 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Added new packet type SILC_PACKET_SET_MODE that is used to
4632 distribute the information about changed modes (for clients,
4633 channels and clients channel modes) to all routers in the
4634 network. Updated the protocol specification accordingly.
4636 Added functions into silcd/packet_send.c and
4637 silcd/packet_receive.c: silc_server_send_set_mode,
4638 silc_server_set_mode.
4640 Added new files silcmode.[ch] into lib/silccore that implements
4641 the encoding and decoding of Set Mode Payload. Added new type
4642 SilcSetModePayload. Moved the definitions of different modes
4643 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4645 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4647 * Oops, a little mistake in server's connection authentication
4648 protocol. The protocol is not ended with FAILURE but with
4649 SUCCESS if the authentication is Ok. :) Affected file is
4652 * Implemented NICK_CHANGE notify handling in server in the file
4653 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4654 the local clients on the channel. After the changing nickname
4655 in router environment snhould work and the [<unknown>] nickname
4656 should appear no more.
4658 The silc_server_replace_id function that receives the Replace ID
4659 payload now sends the NICK_CHANGE notify type also in the file
4660 silcd/packet_receive.c
4662 * Changed WHOIS and IDENTIFY command to support the maximum amount
4663 of arguments defined in protocol specs (3328 arguments). This
4664 fixed a bug that caused problems when there were more than three
4667 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Added extra parameter, command identifier, to the
4670 silc_client_send_command so that explicit command identifier
4673 Changed that ID list routines uses specific command identifier
4674 when sending WHOIS/IDENTIFY requests to the server so that they
4675 can be identified when the reply comes back.
4677 Affected files lib/silcclient/command.[ch],
4678 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4680 * Added `sender' argument to silc_server_packet_send_to_channel
4681 to indicaet the sender who originally sent the packet to us
4682 that we are now re-sending. Ignored if NULL. Affected file
4683 silcd/packet_send.[ch].
4685 * Added some server statistics support in silcd/server_internal.h
4686 SilcServerStatistics structure and around the server code. Also
4687 send some nice statistics information when client is connecting
4690 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Fixed channel ID decoding in server's JOIN command reply in
4693 silcd/command_reply.c
4695 * Fixed braodcasting of replace ID payload to not to send it if
4696 we are standalone server in silcd/packet_receive.c.
4698 * Fixed all channel message sending routines to not to send
4699 packets to clients that has router set, since they are routed
4700 separately in the same function earlier. Affects file
4701 silcd/packet_send.c and all channel packet sending functions.
4703 * In USERS reply, res_argv[i] are not allocated, the table
4704 is allocated. Thus changed that free the table, not its
4707 * In server's whois_check and identify_check if the client is
4708 locally connected do not send any WHOIS commands - they are not
4711 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4713 * Fixed some minor bugs in client when sending WHOIS command. The
4714 arguments was in wrong order.
4716 * Removed statis function add_to_channel from server in
4717 silcd/command.c that was previously used with the joining but
4720 * Tested USERS command in router environment successfully with two
4721 routers, two servers and two clients.
4723 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Reorganized the USERS command and command reply in client library
4726 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4727 When the command is given by user we register a pending command
4728 callback that will reprocess the command after the reply has been
4729 received from the server. When reprocessing the packet we then
4730 display the information. Thus, the USERS information is displayed
4731 now in the command callback instead of in the command reply
4732 callback. The processing of the command is same as previously
4733 when server has sent the command reply in the JOINing process.
4735 * Added to USERS command in silcd/command_reply.c to join the client,
4736 we didn't use to know about, to the channel after we've created
4737 a client entry for it. Also, for clienet we did know already still
4738 check whether it is on the channel or not and add it if not.
4740 * Removed silc_server_command_join_notify as the function and its
4743 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Changed the client's pending command handling to the same as the
4746 server's pending command handling. It is also now possible to
4747 execute command reply functions from other command reply
4748 function as the function callbacks for commands and command
4749 replies are one and same. The pending commands are not static
4750 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4751 in client connection context. Thus, pending commands are server
4752 connection specific as it is convenient.
4754 Changed the function silc_client_command_pending and
4755 silc_client_command_pending_del and added new function
4756 silc_client_command_pending_check. Removed the
4757 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4760 * Added cmd_ident, current command identifier, to the client
4761 connection context in lib/silcclient/client.h to keep track on
4762 command identifiers used in command sending. Client's command reply
4763 function handling now supports the mandatory command identifiers.
4765 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4766 funtions in client to fully support pending command callbacks.
4768 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4769 as one of the arguments to the application in the command reply
4772 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4773 before first releasing SILC but came back. Now it is removed again
4774 and should come back nomore. The FORWARDED flag was used only
4775 by the JOINing procedure by forwarding the command packet to router.
4776 Now, the JOINing procedure has been changed to more generic (due
4777 to various router environment issues) and FORWARDED is not needed
4778 anymore for anything. The protocol specification is yet to be
4781 Now, removed silc_server_packet_forward from server and the flag
4782 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4784 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Renamed NAMES command to USERS command. The NAMES was named that
4787 due to historical reasons. Now it is renamed. Also, rewrote
4788 parts of the USERS command. The nickname list is not sent anymore
4789 by the server. Only Client ID and mode lists are sent in the USERS
4790 command. Changed this also to the protocol specification.
4792 The client now resolves the names and stuff after it receives
4793 the USERS list from the server when joining to the channel.
4795 * WHOIS and IDENTIFY commands has been changed to support multiple
4796 Client ID's per command. One can now search for multiple users
4797 in the network by sending only one WHOIS or IDENTIFY command.
4798 Changed the code and the protocol specifications.
4800 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4801 uses silc_server_command_whois_parse to parse the request. */
4803 * If normal server, do not parse the WHOIS and IDENTIFY requests
4804 before sending it to the router. Saves some time.
4806 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4808 * Fixed JOIN command on client library. Wrong number of arguments
4809 used to crash the client.
4811 * Added silc_server_channel_has_global function to check whether
4812 channel has global users or not.
4814 * Added silc_server_channel_has_local function to check whether channel
4815 has locally connected clients on the channel.
4817 * The silc_server_remove_from_one_channel now checks whether the
4818 channel has global users or not after given client was removed from
4819 the channel. It also checks whether the channel has local clients
4820 on the channel anymore. If it does not have then the channel entry
4821 is removed as it is not needed anymore.
4823 * The silc_server_notify now checks on JOIN notify whether the joining
4824 client is one of locally connected or global. If it is global then
4825 the channel has now global users on the channel and that is marked
4826 to the channel entry. Also, it now saves the global client to
4827 global list who is joining and JOINs it to the channel. This is
4828 for normal server, that is.
4830 Changed silc_server_send_notify_on_channel,
4831 silc_server_packet_relay_to_channel and
4832 silc_server_packet_send_to_channel check if we are normal server
4833 and client has router set (ie. global client) do not send the
4834 message to that client, as it is already routed to our router.
4836 * Implemented LEAVE notify type handling in silc_server_notify
4839 * Tested LEAVE command in router environment successfully. Tested
4840 with two routers, two servers and two clients.
4844 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4846 * Implemented SIGNOFF notify type handling in silc_server_notify
4849 * silc_server_remove_id now removes the client entry from all channels
4850 it has joined and thusly sends SIGNOFF notify type.
4852 * Rewrote the NAMES list generation in server by removing two excess
4853 loops. The lists are created now inside one loop.
4855 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * silc_server_remove_channel_user checks now also global list
4858 for channel and client.
4860 * silc_server_new_channel_user checks now both local and global
4861 list for channel and client. Fixed a bug in client id decoding.
4862 Used to decode wrong buffer.
4864 * silc_server_channel_message checks now both local and global
4865 list for channel entry.
4867 * Tested channel joining (hence JOIN) in router environment
4868 successfully. Tested with two routers, two servers and two
4871 * Tested channel message sending in router environment successfully.
4873 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added silc_server_save_channel_key into server.[ch] to save the
4876 received channel key in Channel Key payload processing. It is
4877 also used in JOIN command reply handling.
4879 Equivalent function silc_client_save_channel_key added into
4880 client.[ch] into client library.
4882 * Changed JOIN command reply to send information whether the channel
4883 was created or not (is existing already) and the channel key
4884 payload. Changed protocol specs accordingly.
4886 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4887 the request was sent by ID and not by nickname. Crashed on
4890 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4893 now correctly save the received data.
4895 * silc_server_free_sock_user_data now notifies routers in the
4896 network about entities leaving the network.
4898 At the same time implemented functions silc_server_remove_id
4899 and silc_server_send_remove_id to receive and send REMOVE_ID
4900 packets. The packet is used to notify routers in the network
4901 about leaving entities. The ID removed will become invalid in
4904 * Added function silc_idlist_del_server into server. Removes and
4905 free's server entry from ID list.
4907 * silc_server_private_message function now checks, if we are router,
4908 that the destination ID really is valid ID, naturally.
4910 * In router when NEW_ID packet is received (for new client) the
4911 hash of the Client ID is saved in the ID Cache but the
4912 client->nickname is set to NULL, instead of putting the hash
4915 IDENTIFY command now also checks that client->nickname must be
4916 valid. If it is not if will request the data from the server who
4917 owns the client. Added new function
4918 silc_server_command_identify_check.
4920 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4921 to set the command to already allocated Command Payload.
4923 * Tested private message sending in router environment with two
4924 routers, two servers and two clients. Fixed minor bugs and now
4927 * Fixed segfault from client's NAMES command. Used to crash if
4930 * Forwarded packets must not be routed even if it is not destined
4931 to the receiver. Changed server code comply with this.
4933 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added `require_reverse_mapping' boolean value to ServerParams
4936 structure. If TRUE (not default) the server will require that
4937 the connecting host has fully qualified domain name.
4939 If the reverse mapping is not required and hostname could not be
4940 found the IP address is used as hostname.
4942 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Implemented version string checking to both client and server.
4945 The check is incomplete currently due to the abnormal version
4946 strings used in development version of SILC.
4948 * Changed all command functions in server to use the new
4951 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Changed char *data to unsigned char *data in ID Cache system to
4954 support binary data as ID Cache data. Changed code to support
4955 binary data in lib/silccore/idcache.c.
4957 * Renamed silc_server_packet_relay_command_reply to
4958 silc_server_command_reply as it is normal packet receiving
4959 function. Rewrote the function to accept command replys for
4960 servers and not only for clients.
4962 * Mark remote router always as registered server if we are connecting
4963 to it. Otherwise, commands sent by the router to us are ignored.
4965 * All ID List find routines now returns the ID Cache Entry pointer
4966 as well if requested.
4968 * WHOIS command works now in router environment, tested with two
4969 routers, two servers and two clients.
4971 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4972 in router environment (as it is almost equivalent to WHOIS) but
4973 hasn't been tested thoroughly. Added new functions:
4975 silc_server_command_identify_parse
4976 silc_server_command_identify_send_reply
4977 silc_server_command_identify_from_client
4978 silc_server_command_identify_from_server
4980 * Disabled route cache adding because adding two different ID's with
4981 same IP replaces the old cache entry thus giving wrong route.
4982 The entry->router->connection is always the fastest route anyway
4983 so route cache may not be needed. Of course, new routes maybe
4984 established after receiving the ID when the entry->router->connection
4985 might not be anymore the most optimal.
4987 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Add route cache for received ID for fast routing.
4991 * Added silc_server_packet_route to route received packet on router
4992 that is not destined to us.
4994 * Renamed silc_server_get_route to silc_server_route_get.
4996 * Added id_string and id_string_len fields into SilcServer to
4997 include encoded ServerID for fast comparing without excess
4998 encoding of the ID's.
5000 * Cleaned up WHOIS command on server side. Added following static
5003 silc_server_command_whois_parse
5004 silc_server_command_whois_check
5005 silc_server_command_whois_send_reply
5006 silc_server_command_whois_from_client
5007 silc_server_command_whois_from_server
5009 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5010 arguments in command replies. All command functions should be
5011 updated to use this macro.
5013 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Minor typo fixes on command reply handling on server.
5017 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Added silc_server_command_add_to_channel internal routine to add
5020 the client to the channel after router has created the channel and
5021 sent command reply to the server.
5023 * Added generic silc_server_send_command to send any command from
5026 * Use static buffer with ID rendering instead of duplicating data.
5028 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Fixed a channel user mode bug when joining to a channel server gave
5031 everybody channel founder rights, oops.
5033 * We mark ourselves as the router of the incoming server connection
5034 if we are router ourselves. This way we can check in some packet
5035 sending functions whether it is locally connected server. For
5036 incoming router connections we put NULL.
5038 * For router sending packets locally means now always sending the
5039 packet cell wide; to local clients and local servers. For normal
5040 server sending packet locally means sending it to only local
5043 * Fixed the JOIN command to really work in router environment. If the
5044 channel is created it is always created by the router. Router is
5045 also responsible of making the initial joining to the channel,
5046 sending JOIN notify to the sending server and distributing
5047 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5048 does not exist server doesn't do anything else but forward the
5049 command to the router which performs everything.
5051 * Added silc_server_send_channel_key function to send the Channel Key
5054 * Added silc_server_create_channel_key to create new channel key. The
5055 channel key is now re-generated everytime someone joins or leaves
5056 a channel, as protocol dictates. Note: channel->key_len is the
5059 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5062 packet_receive.[ch] to separate packet sending and receiving
5063 routines. The server.[ch] now includes everything else including
5064 actual packet processing (writing and reading data) and other
5067 Renamed silc_server_private_message_send_internal to
5068 silc_server_send_private_message. The routine is still though
5069 used only to relay private messages as server does not send
5070 private messages itself.
5072 Renamed silc_server_new_channel to silc_server_create_new_channel
5073 and added new function sicl_server_new_channel that handles the
5074 incoming New Channel packet. Added also new sending function
5075 silc_server_send_new_channel to send New Channel Payload.
5077 * Added new function silc_server_notify to process incoming notify
5078 packet to the server/router. Server may then relay the notify
5079 to clients if needed.
5081 * Added new function silc_server_new_channel_user to process incoming
5082 New Channel User packet. Router will redistribute the packet and
5083 send JOIN notify to its local clients and locally connected servers
5084 if needed. Normal server will send JOIN notify to its local client
5085 on same channel when received this packet. Added also corresponding
5086 sending function silc_server_send_new_channel_user to sent the
5089 * Added boolean route argument to send_notif_to_channel and
5090 packet_send_to_channel functions to attempt to route the packet
5091 if it is TRUE and send only locally if it is FALSE.
5093 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * silc_server_replace_id now broadcasts the received replace ID
5096 packet if it is not broadcast packet already. The router must
5097 broadcast to inform other routers about changed ID.
5099 * Added backpointer to server's router into SilcServer context in
5100 silcd/server_internal.h.
5102 * Fixed silc_server_packet_broadcast to send correct broadcast
5105 * The channel key is now distributed to the local client as soon
5106 as it is received from the router (in router environment) so that
5107 no other packet may be sent for the channel until client has
5110 * silc_server_remove_channel_user now broadcasts the received
5111 Remove Channel User packet if it is not broadcast packet already.
5112 The router must broadcast to inform other routers about removed
5115 * Added users field into SilcPacketContext that is a reference count
5116 of the context. One can increase the reference count by calling
5117 silc_packet_context_dup which is now changed to just increase the
5118 reference count instead of duplicating the data. The reference
5119 count is decresed by calling silc_packet_context_free that will
5120 free the data after the reference count hits zero.
5122 For now on the packet context and everything allocated into it
5123 (including the raw packet from network) must be freed by calling
5124 the new silc_packet_context_free function. Added also new function
5125 silc_packet_context_alloc that must be used now to allocate the
5126 context. This also means that if a routine is asynchronous from
5127 silc_[client/server]_packet_parse_type the packet context must
5128 be duplicated by calling silc_packet_context_dup. Otherwise it
5129 gets free'd after silc_[client/server]_packet_parse_type returns.
5130 Also, one must remember that if packet is duplicated then its
5131 reference count must be decresed by calling the free function as
5132 many times as it was duplicated.
5134 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5135 from both client and server.
5137 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Made joining to a channel working in router environment.
5141 * Cleaned up JOIN command on server side and create function
5142 silc_server_command_join_channel internal routine to make the
5145 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Changed silc_command_pending list to SilcDList. Also, added
5148 `ident' field to SilcServerCommandPending structure to identify
5149 the reply and to call correct callback.
5151 Added silc_server_command_pending_check function to replace the
5152 corresnponding macro. The silc_command_pending list is not
5155 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5156 to set identifier to previously allocated Command Payload. It
5157 is used to set identifier for command when resending Command
5160 * Added silc_command_payload_encode_payload to encode Command
5161 Payload buffer from SilcCommandPayload structure.
5163 * Added silc_argument_payload_encode_payload to encode Argument
5164 payload buffer from SilcArgumentPayload structure.
5166 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Changed WHOIS command to support router connection on server side.
5169 The whois request is always sent to router unless the server is
5170 standalone server. After server has received the reply from the
5171 router will it send the reply to the client.
5173 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5174 broadcast received broadcast packet. The function is used only
5175 by router. The broadcast packet is always sent to the router's
5178 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5179 render given ID to printable string, for log files for example.
5181 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * Made basic router to router connections working. At least they
5184 can now connect to each other but nothing really works the way
5185 they are supposed - yet.
5187 * Added new initiator token to RouterConnection configuration
5188 file in silcd/serverconfig.[ch]. It is used to tell whether we
5189 are the initiator to the remote router or whether we'll expect
5190 the other end to connect.
5192 * Moved registering of listener task to silc_server_init, hence
5193 the server starts listenning as soon as it is run, even if it
5194 does not have connections to other routers. Let's see how well
5197 * Changed default connection retry timeouts for more suitable in
5200 * Removed cipher and such arguments from silc_idlist_add_client
5201 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5202 Added new function silc_idlist_add_data to add the keys and stuff
5205 * Added SilcIDListData structure and added it to SilcClientEntry
5206 and SilcServerEntry as their first field in the structure. This
5207 way we can explicitly cast the ID entries to the SilcIDListData
5208 structure and get common data for the entries. In past, we had
5209 to first check what type of connection it is and then cast it to
5210 correct ID entry type. Now, we can directly cast the opaque
5211 pointer to the SilcIDListData (no matter what ID entry it actually
5212 is) and get the data needed.
5214 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5217 in some circumstances even if threre were timeout tasks, though not
5218 IO tasks, but tasks anyway. Now fixed.
5220 * Defined SilcServerConnection structure to hold connection specific
5221 stuff about directly connected servers and routers. The definition
5222 is currently in silcd/server_internal.h. I thought about having
5223 a bit more important role fro this struct but for now it is used
5224 only when connecting to other server (or router actually).
5226 * Added connecting retry support in server when connecting to
5227 router(s). The retry feature implement exponential backoff
5228 algorithm. Also, added SilcServerParams structure to hold default
5229 parameters for server. For now, it include these retry settings
5230 and are hard coded. After server is moded to be as Silc Server
5231 Library this structure will be more important.
5233 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Changed client librarys channel->clients table to SilcList and
5236 changed code accordingly.
5238 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Changed client's channel table to SilcList and changed code
5241 accordingly. Also changed SilcChannelClientEntry to include back-
5242 pointer to the channel so that client entry can use that structure
5243 as list as well and we have fast cross-reference to the channel.
5244 This change dramatically decreased the complexity of channel
5245 handling with client entry and vice versa (removed one extra
5246 loop when searching for channel entry from many functions).
5248 * Changed server->sim from table to SilcDList and changed code
5251 * NAMES command can now be used from user interface. It will show
5252 the user list on the channel, neatly.
5254 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5255 Code now saves realname of the user if it becomes available.
5257 * Renamed configure.in to configure.in.pre and made ./prepare
5258 script to automatically add correct version string to
5259 configure.in which it creates from configure.in.pre.
5261 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5263 * NAMES command reply now shows users mode with the nickname when
5266 * Moved silc_client_ch[u]mode[_char] functions from
5267 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5268 place sucks, they are utility functions and should be in some
5271 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5273 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5276 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added TRQ (efficient deque and list library) into lib/trq. This is
5281 a very good list library that is currently used in the SILC. Defined
5282 SilcList API over the library because I didn't like the API very
5283 much. See lib/trq/silclist.h for the API and examples of how to
5284 use the API. Fixed various places in the code to use the new
5285 SilcList API. The SilcList is meant for lists that has a structure
5286 already defined as a list. It is not suitable to add just some
5287 context to the list (in TRQ, the context is the list actually).
5289 So, I defined SilcDList that can be used for the purpose where
5290 predefined list structure does not exit. This can be used as
5291 such list. Now some context just can be added to the SilcDList.
5292 Currently this list is not used in the SILC just yet, though there
5293 are a lot places where this can replace dynamically allocated
5294 tables and I will fix these places, later, to use SilcDList.
5295 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5296 and use TRQ internally).
5298 Also fixed some annoying warning messages that the original TRQ
5299 code generated. Also minor changes to TRQ's Makefile.in.
5301 * Added support for querying by Client ID to both WHOIS and
5302 IDENTIFY commands into server, as required by the protocol.
5304 * Removed method function pointers from SilcBuffer structure. They
5305 weren't used to anything and just increased the context size for
5306 no good reason. This change also made silc_buffer_alloc and
5307 silc_buffer_free functions inline functions.
5309 * Disabled command flooding detection support until it's fixed so
5310 that it accepts commands in but does not execute them more than once
5313 * Added silc_net_localhost(), to return local hostname, into
5314 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5315 that must be initialized before calling silc_client_init.
5317 * Added new function: silc_server_send_notify_on_channels to send
5318 notify messages to all channels client has joined. It is assured
5319 that the message is sent only once per client.
5321 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5322 lib/silcutil/silcutil.[ch] as silc_format function. The new
5323 function is generic and is used by server as well, not only by
5324 the logging routines.
5326 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5327 the provided version string was not acceptable. Added new function:
5328 silc_ske_check_version into lib/silcske/silcske.h. The function
5329 must be implemented by the application (client or server) and it
5330 does not reside in the SKE library. The function checks the version
5331 string remote end sent.
5333 * Added back pointers (to opaque context and to SilcSocketConnection)
5334 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5336 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5337 duplicate packet context structure.
5339 * Changed `notify' client operation to send same arguments as client
5340 receives from server except for ID's. ID's are mapped to correct
5341 ID entry and that is returned. Also, if channel entry is not sent
5342 by server but the notify is for channel the channel entry is sent
5343 to application (otherwise application doesn't know that it is for
5344 channel (library gets it from packet's Destination ID)).
5346 * Added silc_client_remove_from_channels into client library to
5347 remove a client from all channels it has joined to. Used when
5348 received SIGNOFF notify from server. Added also new function
5349 silc_client_replace_from_channels to replace old ID entry with
5350 new ID entry on all channels. Used when received NICK_CHANGE
5353 * Fixed ID Cache list handling in silc_idlist_get_client in
5354 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5355 to get (or query) client by ID.
5357 * Updated TODO list.
5359 * Added connection authentication status message defined by the
5360 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5361 support for these into the code in client and server side.
5363 * Added generic function silc_client_send_command to send any command
5364 with variable argument list. Application should use this function
5365 to send commands if the command functions provided by the library
5366 does not suite for the application's user interface needs.
5368 * Added new `failure' client operation. Application is notified about
5369 received failure packet if client is executing a protocol. In this
5370 case the protocol's execution has failed.
5372 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5373 is required by the protocol.
5375 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5376 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5379 * Added status flag to SilcSKE object to indicate realtime status
5380 of the SKE protocol.
5382 * Application receives now exactly same command reply arguments as
5383 the library receives from server. However, if ID is received the
5384 corresponding ID entry is returned to the application (eg. Client
5385 ID is mapped to correct SilcClientEntry entry and that is returned).
5386 Changed command_reply client operation due to this change.
5388 * Changed all ID's in commands and in command replys as ID Payloads.
5389 Change affected both client and server side codes.
5391 All ID's sent in SILC network (with execption of ID's in SILC
5392 Packet header) are sent in ID Payload to support variable length
5395 * Server now notifies nick changes and notifies all clients on
5396 the channels about the new nickname (about the new Client ID,
5399 * Implemented CMODE command to change channel modes. Supports all
5400 channel modes defined by the protocol specs except ban and invite
5401 lists. (Also, private channel key mode is supported but support for
5402 setting private channel key in client is missing, thus, this mode
5403 has no effect on client side (except that server requires that the
5404 client uses private channel key and normal channel traffic does not
5407 Also, invite mode works per se, but INVITE command does not work
5408 yet correctly, so you can set channel as invite only channel but
5409 inviting clients to the channel does not work (it is yet to be
5410 thought what's the best way to do it).
5412 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5413 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5414 Implemented CUMODE command to change user's mode on the channel.
5415 Supports all modes defined by the protocol specs.
5417 * Added NAMES command reply to return users modes on the channel.
5419 * Removed unnecessary and slow ciphers from lib/silccrypt.
5421 * Set SO_KEEPALIVE option to connection sockets by default.
5423 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5425 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5426 redefined the Notify Payload into protocol specs.
5428 * Added silc_id_payload_parse_id to get ID directly from raw
5431 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5434 accept searching by Client ID as well.
5436 * Added support for LEAVE and SIGNOFF notify types in client library.
5438 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5439 to parse ID Payload from raw data.
5441 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5443 * Added flags parameter into silc_ske_assemble_security_properties
5444 function in lib/silcske/silcske.[ch].
5446 * Changed notify client operation to fit better for notify messages
5447 sent by server. The notify payload received from server is now
5448 passed to the application (after parsing it to SilcNotifyPayload).
5449 It is application's responsibility to retrieve the arguments
5450 from the payload and show the message the way it wants. The message
5451 sent by server is implementation specific.
5453 * Changed public keys to comply with the protocol specification.
5454 Old public keys are not supported anymore and are not compatible.
5456 * Removed nickname from Channel Payload as the latest draft removed
5457 it. The client must resolve the nickname from the NAMES command
5458 reply received when it joined the channel.
5460 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5462 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Fixed some errors in protocol specification drafts.
5466 * Created lib/silccore/silcnotify.c to implement Notify Payload
5467 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5468 generic payloads described by protocol specifications. The file
5469 includes implementations for ID Payload and Argument Payload.
5471 * Changed Command Payload implementation to use the new Argument
5472 Payload. Changed command_xxxx_payload to command_payload_xxxx
5473 to comply with SILC coding conventions.
5475 * Added suppport for Argument Payload handling in Notify Payload
5476 implementation as protocol requires it. Added the new support
5477 into server and client lib as well.
5479 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Added support for multiple nicknames on same channel. [n] is
5482 added locally to the nickname if there are more than one same
5483 nicknames on the channel.
5485 * Server now sends all nicknames that matched WHOIS request.
5486 Client also shows the list received from server.
5488 * Added TOPIC command to client side. User can now set and show
5489 current topic on channel.
5491 * Added MOTD command to client and server. Also, server sends the
5492 motd when client connects to the server.
5494 * Changed version strings to comply ISO 8601.
5496 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed protocol error handling in client library. It should now
5499 cope even if the SKE fails for some reason.
5501 * Made new protocol specification drafts for submitting to IETF.
5503 * Implemented TOPIC command to server in silcd/command.c.
5505 * Added two new notify types into lib/silccore/silcnotify.h:
5506 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5507 notify nickname change and topic setting/change on a channel.
5509 * API change of command_reply operation in client library. The
5510 application gets now the status type received from server as well.
5512 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5516 * Cras fixed and optimized the packet handling even further and
5517 it should work now. Minor change to the prototype of function
5518 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5520 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Added new function into lib/silcutil/silcschedule.[ch]:
5523 silc_schedule_with_fd to select() a specified fd. The function
5524 returns after timeout expires or data arrives or goes. The
5525 function is used by packet routines to wait that all data is
5526 received from network.
5528 * Fixed data reading from network in lib/silccore/silcpacket.c.
5529 The code now assures that all data is read from the fd and then
5530 continues packet processing. This was a bug fix since the code
5531 used to drop some data in some circumstances.
5533 * Added new function into lib/silcclient/client.[ch]:
5534 silc_client_start_key_exchange to start key exchange after
5535 connection has been established to server. The code internally
5536 now uses this funtion but its main purpose was to provide it
5537 for applications that perform their own connecting. After
5538 application has created a connection it merely calls this
5539 function to start the key exchange between client and server.
5540 The library takes care of everything else after that.
5542 Updated also lib/silcclient/README to explain the usage of
5545 * Do not send to application information that connection has
5546 been established. Application gets notified it by connect
5549 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Applied cras's patch to add silc_schedule_one function. The
5552 function runs scheduler once and returns.
5554 * Fixed the scheduler after cras messed it up. The timeout
5555 handling works now as it's supposed to work.
5557 * Added into lib/silccore/ silcnotify.h to include notify
5558 message types support. Changed silc_server_send_notify*
5559 functions, in server.[ch], to support those new notify types.
5560 Added the support for the notify types into client library,
5561 as well. Added new notify client operation into ops.h in
5564 * Changed silc_server_packet_send_to_channel to send normal
5565 packets instead of just channel message packets. The function
5566 is now used to send the notify packets to channels. It is not
5567 used to send channel message packets anymore, as server never
5570 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5571 va_arg()s as it seems to require it nowadays. I guess, if SILC
5572 is compiled with older va_arg() the new code should work anyway.
5574 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Splitted core library. Core library (lib/silccore) includes
5577 now only SILC protocol specific core (and common) components.
5578 Created new utility library (lib/silcutil) that includes more
5579 generic purpose stuff. The stuff for util library was taken
5580 from the old core library. This was minor and easy split.
5582 * Created SILC Client Library (lib/silcclient) that includes
5583 implementation of the SILC client without user interface. This
5584 was major move from silc/ directory. The code has been changed
5585 so that it is transparent towards the user interface. The
5586 silc/ directory includes now the same user interface as before
5587 and it uses the new client library. Read lib/silcclient/README.
5588 Basicly, the client library performs everything else related
5589 to SILC except user interface handling. Also, configuration
5590 files are considered to be part of user interface and library
5591 does not handle them.
5593 This change also changed a lot of structures, function naming etc.
5594 Most important change was that SilcClientWindow object was
5595 renamed to SilcClientConnection in the client library. Created
5596 also new file lib/silcclient/ops.h. Also added new files
5597 silc/local_command.[ch] and silc/client_ops.[ch].
5599 All these changes were made to make it easier for user interface
5600 designers to create what ever user interface for the SILC client
5603 It is also expected that the server will be moved to lib
5604 directory as well and SILC Server Library will be created;
5605 sometimes in the future.
5607 * Removed Local commands from lib/silccore/silccommand.h as
5608 they are application specific and new client library does not
5609 handle any of those anymore.
5611 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5612 old client implementation in silc/.
5614 * Added support for callback functions in SILC_LOG_* macros.
5615 Application can now set its own callbacks that will be called
5616 instead of using the default functions that will always print
5617 the debug messages to stderr (or stdout). Also, debugging can
5618 now be disabled by setting silc_debug to FALSE and re-enabled by
5619 setting it to TRUE. Note, that logging will still work even
5620 if debugging is disabled.
5622 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5623 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5624 silc_log_reset_debug_callbacks.
5626 * To enable debugging in silc client one must give now -d
5627 option on command line.
5629 * Changed silc_schedule_init to automatically allocate task queues
5630 if they are not allocated before calling it.
5632 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Added GMP 3.1 into math library.
5636 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5639 a channel in SILC network. The packet is used by servers and
5640 routers to notify other routers that user has left a channel.
5641 This little feature was missing until now. Added the feature
5642 to protocol specification as well.
5644 Added functions: silc_server_send_remove_channel_user and
5645 silc_server_remove_channel_user into server.[ch].
5647 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5648 lib/silccore/silcpacket.h. However, they are not implemented
5651 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Fixed joining to a channel and sending channel messages
5654 between server and router. The channel message sending should
5655 now work inside a cell.
5657 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Fixed the private message sending between server and router.
5660 The private message sending should now work inside a cell.
5662 * Added silc_server_replace_id into server.[ch] to replace
5663 existing ID in the SILC network.
5665 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5666 and silc_idlist_replace_server_id into idlist.[ch] in server.
5668 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Fixed the server to server connections. Server can again now
5671 connect to router. Router to router connections probably does
5674 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added dynamic protocol registering support. Now protocols can
5677 registered and unregistered on the fly. Patch by cras.
5679 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5681 * Added lib/contrib directory to hold routines that some platforms
5682 don't have but are needed by SILC.
5684 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5685 into lin/contrib to provide getopt() and getopt_long() for
5686 those who don't have it.
5688 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added AWAY command to client. When away message is set and
5691 client receives a private message packet the client automatically
5692 replies to the sender with the away message.
5694 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5695 bug seemed to be the cause of recent problems when compiling
5698 * Added version detection support to SKE protocol specification
5699 and added the new changes to the SKE implementation as well.
5700 There were other minor changes in the SKE protocol as well.
5702 Many changes in lib/silcske/silcske.[ch] and in
5703 lib/silcske/payload.[ch].
5705 * Added ^U functionality, clear input line. Patch from cras.
5707 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Mainly small bugfixes on core library. Fixed some debugging
5710 logging and buffer overflow in silclog.c.
5712 * Updated config.sub and config.guess on the distribution tree.
5714 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Added command lagging support in server. Client may execute
5717 commands now only once in two seconds.
5719 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Optimized packet reception. MAC computation and checking is now
5722 also more optimized. A lot previously duplicated code is now
5723 used as generic by both client and server.
5725 * Fixed key pair generation in clientutil.c
5727 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Added into lib/silccore/silcbufutil.[ch] new function;
5730 silc_buffer_realloc.
5732 * Moved generic packet sending/encryption functions to
5733 lib/silccore/silcpacket.[ch] from client and server. Some
5734 rewriting of the functions.
5736 * Moved all generic packet reception/decryption functions to
5737 lib/silccore/silcpacket.[ch] from client and server. The
5738 packet processing is now much cleaner in both client and server.
5739 These were major changes in both client and server.
5741 * Created many common functions in server to do packet sending.
5742 Previously code were duplicated a lot, this has been removed
5745 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Rewrote major parts of the ID cache system. Don't know
5748 whether it is better now or not but at least the API is more
5751 * Major rewrite on ID cache stuff on client because of the ID
5752 cache API changes. Added idlist.c to client.
5754 * Also major rewrite on ID cache stuff on server as well.
5755 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5756 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5757 in hand, instead they are all put into the ID cache system now.
5758 All server_idlist_* routines uses ID cache now instead of
5759 traversing its own lists (those lists does not exist anymore).
5760 SilcIDList though still exists. Also, SilcXXXEntry's are
5763 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Finally made the SKE implementation compliant to the protocol
5766 specification. All mp integers are now binary encoded as
5767 opposed being HEX encoded.
5769 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5772 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5773 functions: silc_[encode/decode]_pem. Also added function
5774 silc_encode_pem_file to PEM encode with newlines ('\n') for
5777 * SILC public keys are now encoded either PEM or binary. Same
5778 option is for private keys as well. By default private keys
5779 are binary encoded and public keys PEM encoded. Silly HEX
5780 encoding were removed.
5782 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5783 function to create fingerprints.
5785 * Fixed a bug in SHA1; does not change the original data anymore.
5787 * Partly implemented INFO command on client and server side.
5788 Fixed CLEAR command. Changes to SERVER command; show current
5789 server(s) when giving command without arguments. Added
5790 VERSION command to client.
5792 * Added check to server that unregistered connections cannot
5793 execute commands (unless it is specificly allowed).
5795 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Fixed screen refresh.
5799 * Fixed channel joining bug from client. On some circumstances
5800 client tried to join to a channel it had already joined.
5802 * Added public key verification process into client's protocol.c.
5803 The client now verifies the public key from user and saves
5804 it into ~./silc/serverkeys/ directory.
5806 Added into: clientutil.[ch]: silc_client_verify_server_key.
5808 * Changed SKE protocol's silc_ske_initiator_finish function
5809 to accept callback function that verifies the received public
5810 key. Removed old silc_ske_verify_public_key function.
5812 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5815 silc_pkcs_private_key[_data]_set.
5817 * Made the password and public authentication more cleaner in
5818 server's protocol.c.
5820 * Removed historic and obsolete protocol `channel_auth' from
5821 both client and server.
5823 * Removed wrong way of sending command status messages from
5824 server to client in server's command.c. The old way violated
5825 protocol specification.
5827 Changes to silccore/silccommand.[ch]: removed
5828 silc_command_encode_status_payload -> not needed anymore,
5829 changed silc_command_encode_payload_va to accept extra
5830 argument on variable argument list. The argument type must
5831 now be provided to the function. Also, added new function:
5832 silc_command_encode_reply_payload_va which is same as
5833 normal command_encode_payload_va except command status type
5834 is provided as extra argument.
5836 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Added ~./silc directory handling. The directory includes the
5839 public and private keys for the client.
5841 Added silc_client_check_silc_dir, silc_client_create_identifier
5842 and silc_client_load_keys.
5844 * Implemented SILC protocol compliant public key. Added public
5845 and private key saving to and loading from files.
5847 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5848 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5849 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5850 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5851 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5853 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5854 silc_pkcs_load_[public/private]_key.
5856 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Added silc_server_get_route (route.[ch]) to get connection
5859 data for the fastest route for given ID.
5861 * Implemented INVITE command on client and server. The command
5862 were re-defined in the SILC Protocol Specification and the
5863 implementation now complies with the specification.
5865 * Implemented PING command on client and server.
5867 * Implemented NAMES command on client and server. The server side
5868 supports currently only normal server not router server yet.
5869 Some changes to NAMES definition in SILC protocol specification.
5871 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Implemented LEAVE command on client and server.
5875 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5876 again. This change was made to the protocol as well. Server
5877 should not violate the protocol specification anymore.
5879 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5882 was tested. SOCKS4 was not but should work anyway.
