20 * Added silc_pkcs_public_key_compare to compare two
21 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
23 * Check that the client who set the founder mode on the
24 channel is the same client that is giving the founder
25 mode to itself. It is done by comparing the saved public
26 key (it is saved even in the authentication is passphrase).
27 Affected file silcd/command.c.

37 * Fixed the silc_client_packet_parse to not to increase
38 the packet sequence number if the conn->sock and the
39 current socket connection is not same. This can happen
40 for example during key agreement when the conn includes
41 multiple socket connections (listeners). Affected file
42 lib/silcclient/client.c.
44 * The sender of the file transfer request now provides also
45 the pointer (listener) for the key exchange protocol. If
46 the listener cannot be created then it sends empty key
47 agreement and lets the receiver provide the listener.
49 Added `local_ip' and `local_port' arguments to the
50 silc_client_file_send. If they are provided they are used,
51 if not then it will attempt to find local IP address, if
52 not found or bind fails then the remote client will provide
55 Affected files are lib/silcclient/client_ftp.c and
56 lib/silcclient/silcapi.h.
58 * Extended the FILE SEND command to support defining the

65 of the client's public key (if the proof of posession of the
66 corresponding private key is verified by the server).
67 Updated to the protocol specification.
69 * Added support of receiving the client's public key's
70 fingerprint in command reply in client library. Affected
71 file is lib/silcclient/command_reply.c, and
72 lib/silcclient/idlist.[ch].
74 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

130 during SERVER_SIGNOFF, but invalidate it. This way we
131 preserve the WHOWAS info for the client. Affected file
134 * Fixed SERVER_SIGNOFF notify handling in the server. The
135 server is now able to process incoming SERVER_SIGNOFF notify
136 for a server that it doesn't even know about. It will remove
137 the clients provided in the notify. Affected file
138 silcd/packet_receive.c.
140 * Check for partial packet in data queue after every packet that
141 was found from the queue. Return and wait for more data if

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

219 * Added silc_net_localip to return local host's IP address.
220 Affected file lib/silcutil/silcnet.[ch].
222 * If key exchange or rekey protocol is active for a connection
223 parse all packets syncronously since there might be packets
224 in packet queue that we are not able to process without first
225 processing packets before them. Affected file silcd/server,
226 lib/silcclient/client.c.
228 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
229 whether library should continue processing the packet.
230 Affected file lib/silccore/silcpacket.h.

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

303 * Call the silc_server_udpate_servers_by_server in the
304 primary router that comes back online in the backup resuming
305 protocol. Otherwise it routes packets wrong. Affected file
306 silcd/server_util.[ch], silcd/server_backup.c.
308 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the

313 * Redefined the SILC packet header to include the padding
314 length. Affected file lib/silccore/silcpacket.[ch].
316 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
317 length for maximum padding up to 128 bytes). Affected
318 file lib/silccore/silcpacket.h.
320 * Removed all backwards support for old 0.5.x MAC thingies.
321 The SILC packet header change makes it impossible to be
322 backwards compatible.
324 * Send the ENDING packet with timeout in the backup resuming
325 protocol. This is to assure that all routers has connected
326 to the primary router. Affected file silcd/server_backup.c.
328 * Changed the RNG to take the first IV from random data. It
329 used to take it from zero actually. Changed the RNG also
330 to use /dev/urandom during session. /dev/random is used
331 in initialization. Affected file lib/silccrypt/silcrng.[ch].
333 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
335 * Changed the SILC packet header to have the first two bytes
336 (the packet length) encrypted. Affected files aroung the
337 code tree, lib/silccore/silcpacket.[ch]. Removed the
338 SilcPacketCheckDecrypt callback. It is not needed anymore
339 since the silc_packet_receive_process will determine now
340 whether the packet is normal or special.
342 * Implemented the unidirectional MAC keys. Affected files
343 lib/silcske/silcske.c, silcd/protocol.c and
344 lib/silcclient/protocol.c.
346 * Implemented the packet sequence number to the MAC computation.
347 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
348 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
349 lib/silcclient/protocol.c.
351 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
353 * Allow backup router to announce servers. All servers
354 announced by backup router are added to the global list
355 automatically. Update hte server's socket to our primary
356 router also when backup router announces a server.
357 Affected file silcd/packet_receive.c.
359 * Do not update the client->router in the function
360 silc_server_udpate_clients_by_server if the client is on
361 global list. We might fail to find any specific server
362 for locally connected clients and local cell clients. They
363 should still use the `from' and not `to' as client->router.
364 This fixes backup router resuming protocol. Affected file
367 * Decrease channel statistics count only if the channel
368 deletion worked. Affected files are silcd/server.c and
371 * Added silc_server_update_servers_by_server to update origin
372 of all server entries. Used during backup router protocol.
373 Affected files silcd/server_util.[ch], silcd/server.c. and
374 silcd/backup_router.c.
376 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
377 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
378 silc_hmac_get_hash and silc_hmac_get_name. Affected file
379 lib/silccrypt/silchmac.c.
381 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
383 * Assure that router cannot reroute the same channel message
384 to the sender. Affected file silcd/packet_receive.c.
386 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
388 * Made better checks that the channel message is not sent
389 to the router it came from. Affected file is
390 silcd/packet_send.c. Fixed memory leak too.
392 * Announce informations for incoming router connection, but
393 only after checking if it is replaced by backup router.
394 Affected file silcd/packet_receive.c.
396 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
398 * Fixed the backup resuming protocol to work in multiple
399 router environment. Affected file silcd/server_backup.c.
401 * Route packet only to one router in the function
402 silc_server_packet_send_to_channel. Affected file is
405 * Fixed silc_server_send_notify_dest to set the broadcast
406 flag. Fixed the silc_server_send_notify_topic to actually
407 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
408 Affected file silcd/packet_send.c.
410 * Changed the SFTP Filesystem interface. Changed the
411 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
412 the filesystem operation function. The SilcSFTPFilesystem
413 is now a context that is allocated by all filesystem allocation
414 functions and it already includes the operations structure
415 and filesystem specific context. It is given as argument
416 now to the silc_sftp_server_start. This made the interface
417 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
418 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
420 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
422 * Changed the backup router adding and getting interfaces
423 in the server. The router that will be replaced by the
424 specified backup router is now sent as argument. Affected
425 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
428 * Added silc_net_addr2bin_ne to return the binary form of
429 the IP address in network byte order. Affected files
430 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].

445 * Wrote the definition of the backup resuming protocol to the
446 protocol specification.
448 * Removed one redundant channel key generation from normal
449 server during joining procedure. Removed one redundant
450 channel key sending from server to router during joining
451 procedure. Affected file silcd/command.c.
453 * Made minor bugfixes to the backup router resuming protocol.
454 Affected file silcd/server_backup.c, server.c.
456 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

463 resume the primary router position in the cell after the
464 primary router comes back online. Affected files
465 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
466 and silcd/server_util.[ch].
468 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
470 * Sleep two (2) seconds after sending QUIT command to server.
471 Affected file lib/silcclient/command.c.

474 send any data. Affected file silcd/packet_send.c.
476 * Assure that if outgoing data buffer is pending do not force
477 send any data. Affected file lib/silcclient/client.c.
479 * Implemented the backup router support when the primary router
480 goes down. The servers and routers can now use the backup
481 router as new primary router without loosing connectivity.
483 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
485 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
486 in the server to indicate disabled entry. All data read
487 from the connection will be ignored and no data is sent
488 for entry that is disabled. Affected files are
489 silcd/idlist.h, silcd/server.c.
491 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
493 * Created SFTP client and server test programs in the
494 lib/silcsftp/tests directory.
496 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
498 * Implemented memory filesystem (virtual filesystem) for
499 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
502 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
504 * Implemented the SFTP (SSH File Transfer Protocol) to the
505 lib/silcsftp. It includes SFTP client and SFTP server
508 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
510 * Moved lib/silccore/silcprotocol.[ch] to the
511 lib/silcutil library.
513 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
514 take variable argument list pointer as argument. Affected
515 file lib/silcutil/silcbuffmt.[ch].
517 * Added silc_buffer_set function that is used to set data
518 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
519 Affected file lib/silcutil/silcbuffer.h.
521 * Changed various routines in the core library to use the new
522 silc_buffer_set instead of allocating new buffer only for
525 * Added 64-bit value formatting and unformatting support to the
526 silc_buffer_[un]format routines. Affected file is
527 lib/silcutil/silcbuffmt.[ch].
529 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
530 to includes/bitmove.h.
532 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
534 * Fixed channel user mode saving in client library. Affected
535 file lib/silcclient/command[_reply].c.
537 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
539 * Defined the file transfer to the SILC Protocol. Added
540 new packet type SILC_PACKET_FTP and defined File Transfer
541 Payload. The mandatory file transfer protocol is SFTP
542 (SSH File Transfer Protocol). Affected file in addition
543 of the internet draft is lib/silccore/silcpacket.h.
545 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
546 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
547 is used as part of backup router protocol when the primary
548 router of the cell is back online and wishes to resume
549 the position as primary router.
551 * Redefined the MAC generation keys in the protocol. The
552 same key is not used anymore in both direction. Both
553 direction will now use different keys for sending and
554 receiving. This fixes a potential security flaw. This
555 change causes incompatibilities in the protocol.
557 * Redefined also the MAC computation from the packet.
558 An packet sequence number is now added to the MAC
559 computation. This prevents possible replay attacks against
560 the protocol. This change too causes incompatibilities
563 Added `sequence' field to the SilcPacketContext to hold
564 the current sequence number for the packet.
566 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Added `created' field to the SilcIDListData in the file
569 silcd/idlist.h to indicate the time when the entry was
572 * Added `created' field to the SilcChannelEntry too. Affected
575 * Added `creation_time' aguments to all the announcement functions
576 in the server. If it is provided then only the entries that
577 was created after the provided time frame are actually
578 announced. Affected file silcd/server.[ch].
580 * The protocol says that the Channel ID's IP address must be
581 based on the router's IP address. Added check for this in
582 the silc_server_new_channel when processing incoming New Channel
583 Payload. Affected file silcd/packet_receive.c.
585 * Print out the correct version with --version in SILC client.
586 Affected file irssi/src/silc/core/silc-core.c.
588 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
590 * Fixed WHOWAS command to check for completnes of the client
591 entry always, not just when the command is coming from client.
592 Affected file silcd/command.c.
594 * Added new function silc_server_packet_queue_purge to purge the
595 outgoing data queue to the network. After the function returns
596 it is guaranteed that the outgoing packet queue is empty.
597 Affected file silcd/packet_send.[ch].
599 * Purge the outgoing packet queue in the rekey protocol's final
600 callback to assure that all rekey packets go to the network
601 before quitting the protocol. Affected file silcd/server.c.
603 * Added silc_client_packet_queue_parse as similar function as
604 in server to the client library. The affected file is
605 lib/silcclient/client.c.
607 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Splitted silcd/server.c and created silcd/server_util.[ch]
610 for utility functions.
612 * Added new socket flag SILC_SF_DISABLED to indicate that the
613 connection is open but nothing can be sent to or received from
614 the connection. Affected file lib/silcutil/silsockconn.[ch].
615 The checking for disabled socket is checked in the low level
616 silc_socket_write and silc_socket_read functions.
618 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
620 * Allow only nicknames and channel names that fits into the
621 7-bit unsigned char ASCII set. Affected file silcd/command.c.
623 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
625 * When processing JOIN command reply in server check that if
626 the channel exists in our global list we'll move it the local
627 list. Affected file silcd/command_reply.c.
629 * Fixed the check whether client is joined on the channel already
630 in JOIN command. Affected file lib/silcclient/command.c.
632 * Fixed the JOIN command reply to check whether the channel
633 already exists. Affected file lib/silcclient/command_reply.c.
635 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Added silc_ske_status_string to map the SKE error numbers
638 to readable strings. The affected files are
639 lib/silcske/silcske[_status].[ch].
641 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
643 * Do not show the private channels on the WHOIS channel list
644 as it is not allowed by the protocol. The affected file is
647 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
649 * Assure that the packet length digged from the actual packet
650 is something sensible in the silc_packet_decrypt_rest_special
651 in lib/silccrypt/silcpacket.c.
653 * Free and NULL the allocated pointer in silc_hmac_alloc if
654 the HMAC allocation fails. The affected file is
655 lib/silccrypt/silchmac.c.
657 * Print the selected security properties to the log files in
658 the server. Affected file silcd/protocol.c.
660 * Add SKE's reference counter even if calling the completion
661 callback manually. Otherwise it goes negative, although it
662 does not cause any problems. The affected file is
663 lib/silcske/silcske.c.
665 * Remove the client entry with short timeout after giving the
666 KILL command. Affected file lib/silcclient/command.c.
668 * Fixed to send error reply in WHOIS and IDENTIFY commands in
669 case all found clients are already disconnected (WHOWAS would
670 found them) in the server. Affected file silcd/command.c.
672 * Update the last_receive (time of last data received) to be
673 updated only when received private or channel message so that
674 the idle time showed in WHOIS makes more sense.
676 * Added boolean field `valid' in to the SilcClientEntry in the
677 client library to indicate whether the entry is valid or not.
678 This fixes the nickname change bug on channel when changing
679 the nickname to be same than the old (like nick to Nick) the
680 nickname formatter doesn't set the new nick anymore to Nick@host.
681 Affected file lib/silcclient/idlist.[ch].
683 * Now actually fixed the nickname changing on disconnection.
684 Added new function silc_change_nick to the Irssi SILC Client.
685 Affected file irssi/src/silc/core/client_ops.c,
686 irssi/src/silc/core/silc-nicklist.[ch].
688 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
690 * Check that the public key exists in the GETKEY command before
691 trying to encode it. Affected file silcd/command.c.
693 * Print some notifications on received public keys with GETKEY
694 command in the Irssi SILC Client. Affected files are
695 irssi/src/fe-common/silc/module-formats.[ch],
696 irssi/src/silc/core/client_ops.c.
698 * Use IDENTIFY command to resolve the server information in the
699 GETKEY command instead of INFO command. Affected file
700 lib/silcclient/command.c.
702 * All command reply functions in the client library now calls
703 the pending command reply callbacks even if an error has
704 occurred. The server has done this a long time and now it was
705 time to move the client library to this as well. Now all
706 errors can be delivered back to the pending command reply
707 callbacks if necessary. Affected files are
708 lib/silcclient/command[_reply].[ch].
710 * Change the nickname on disconnection back to the username
711 because in reconnect the server will enforce it to it anyway.
712 Affected file irssi/src/silc/core/silc-servers.c.
714 * Fixed a config file parsing bug in the Irssi SILC client.
715 Affected file irssi/src/silc/core/clientconfig.c.
717 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
719 * When printing the channel mode on JOIN, verify that the
720 channel key and channel's HMAC are valid. Affected file
721 irssi/src/silc/core/client_ops.c.
723 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
725 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
726 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
727 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
729 * Removed channel key rekey task deleting from the function
730 silc_server_save_channel_key. Affected file silcd/server.c.
731 Added explicit timeout task context instead that is used to
732 delete the task if we are registering a new task before the
733 new task has elapsed.
735 * When channel key rekey occurs the client library now saves
736 the old channel key for a short period of time (10 seconds) and
737 is able to use it in case some is still sending channel
738 messages encrypted with the old key after the rekey. Affected
739 file lib/silcclient/[idlist.h|client_channel.c].
741 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Added check to the silc_server_new_id_real to not accept
744 new ID if it is the sender's own ID. Affected file is
745 silcd/packet_receive.c.
747 * Assure that we do not announce ourself or the one we've
748 sending our announcements when we're router and are announcing
749 servers to our primary router. Affected file silcd/server.c.
751 * Fixed silc_server_command_identify_check_client to assemble
752 correct WHOIS packet. It send corrupted WHOIS packet and
753 caused problem with router to router connections. Affected
754 file silcd/command.c.
756 Fixed also silc_server_command_whois_check the same way
757 as for the IDENTIFY command.
759 * Added new SilcIDListStatus to the server in the SilcIDListData
760 structure. The status now includes the current status of
761 the entry (like registered, resolved etc.). Affected file
762 silcd/idlist.[ch]. Defined a bunch of different status types
763 as well. This replaced the old boolean registered field as well.
765 Added resolve_cmd_ident field to the SilcClientEntry structure
766 too so that if the entry is for example being resolved so
767 another command may attach to the same pending command reply
768 without requiring to resolve the same entry again. This concept
769 should optimize the WHOIS and the IDENTIFY resolving under
770 heavy load by taking away unnecessary resolving for entries
771 that are being resolved already.
773 Added support for adding multiple pending commands for one
774 command idenfier. Affected file silcd/command[_reply].[ch].
776 * Fixed WHOIS and IDENTIFY save to remove the cache entry
777 before deleting the data. Otherwise the hash table will have
778 freed data in comparison functions. Affected file is
779 silcd/command_reply.c.
781 * Fixed silc_idlist_replace_client_id to add the new entry to
782 the cache with NULL nickname. Otherwise there will be invalid
783 memory as the nickname after the nickname is freed. Affected
784 file silcd/packet_receive.c.
786 * Fixed the silc_idlist_get_clients_by_hash. The entries was
787 saved into wrong slots because the previous number of entries
788 was not taken into account. Affected file silcd/idlist.c.
789 Fixed same thing in silc_idlist_get_clients_by_nickname too.
791 * If we are router and we receive JOIN notify to a channel that
792 does not have any users then notified client is marked as the
793 channel founder, as it is it. The affected file is
794 silcd/packet_receive.c
796 * Added to the extended hash table API's table_del_*ext functions
797 the destructor as argument too, so that the caller can decide
798 which destructor to use or whether to use destructor at all.
799 Affected file lib/silcutil/silchashtable.[ch].
801 * Fixed ID Cache purging. It actually deleted the entries from
802 the hash table after the data was freed. The hash table ended
803 up comparing freed memory. The affected file is
804 lib/silccore/silcidcache.c.
806 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
808 * Fixed Irssi SILC client's KILL command's HELP syntax.
810 * The USERS command now resolves the detailed user information
811 if the userinfo field is missing. Affected file is
812 lib/silcclient/command_reply.c.
814 * Do not print error in silc_file_read if the read file does
815 not exist. Just silently return NULL. Affected file is
816 lib/silcutil/silcutil.c.
818 * Fixed the silc_log_output to not wine about NULL filename
819 and to not create some bogus " " filename. Affected file is
820 lib/silcutil/silclog.c.
822 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
824 * Fixed various printing bugs on the user interface in the
825 Irssi SILC Client. Minor changes that were forgotten from
828 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
830 * Fixed the configure.in.pre and the compilation and distribution
831 environment to support the new autoconf 2.52. That version is
832 now required to compile the CVS trunk.
834 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
836 * Renamed function silc_parse_nickname to silc_parse_userfqdn
837 to generally parse user@fqdn format strings. Affected file
838 lib/silcutil/silcutil.c.
840 * Added nickname_format and nickname_force_format fields to the
841 SilcClientParams structure. The first one defines the format
842 for the nicknames that the library will enforce if the receives
843 multiple same nicknames. The second one is boolean value and
844 can be used to force the library to always enforce the format
845 to the nicknames regardles whether there are multiple nicknames
846 or not. This configurable formatting was employed to flexibly
847 support accessing multiple nicknames from the user interface.
848 The userinterface can now set the nicknames to what ever format
849 they prefer. Affected file lib/silcclient/silcapi.h.
851 Added function silc_client_nickname_format to the file
852 lib/silcclient/idlist.c. It performs the nickname formatting.
854 Added new field `hostname´ to the SilcClientEntry context.
855 It holds the hostname of the client. Affected file is
856 lib/silcclient/idlist.h.
858 * Irssi SILC Client sets the nicknames in nick@hostn format.
859 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
860 irssi/src/silc/core/silc-core.c.
862 The WHOIS printing now also shows both the real nickname and
863 the formatted nickname so that user knows how to access the
864 user if there are multiple same nicknames cached. Affected
865 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
866 printing formatting too to take the hostname now as a separate
867 argument. The Affected file is
868 irssi/src/fe-common/silc/modules-formats.[ch].
870 * Changed the silc_client_get_clients_local to accept the formatted
871 nickname as argument. It accepts the real nickname too but the
872 formatted nickname can be used to find the true entry from
873 multiple entries. Affected file lib/silcclient/silcapi.h and
874 lib/silcclient/idlist.c.
876 * Added nickname_format_parse field to the SilcClientParams.
877 It is a callback function provided by the application to parse
878 the nickname out of the formatted nickname string. The library
879 calls it to get the nickname from the formatted string. Since
880 the application generally knows better the format of the nickname
881 string it parses it instead of the library, even though library
882 encodes the formatted string. If the callback function is not
883 provided then the library will use the string as is. The
884 affected file is lib/silcclient/silcapi.h.
886 * All the nickname strings passed to the client library in
887 commands are now expected to be formatted nickname strings.
888 If the command does not support the formatted nickname string
889 it will assume that the sent string is the actual nickname.
890 Affected file lib/silcclient/command.c.
892 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
894 * Added public key authentication support to OPER and SILCOPER
895 commands in the client library. Affected file is
896 lib/silcclient/command.c.
898 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Changed the get_auth_methdod client operation to be asynchronous.
901 It can be async if the application resolves the authentication
902 method from the server during the negotiation. Added new
903 SilcGetAuthMeth completion callback that the application will
904 call after resolving the authentication method.
906 Added function silc_client_request_authentication_method that
907 the application can use to resolve the authentication method
908 from the server. Added also SilcConnectionAuthRequest callback
909 that the library will call after the server has replied. The
910 application can call this function if it does not know the
911 current authentication method.
913 Affected files are lib/silcclient/client.c and
914 lib/silcclient/silcapi.h.
916 * The Irssi SILC client now automatically resolves the authentication
917 method incase any configuration information is not present (and
918 currently there never is). The affected file is
919 irssi/src/silc/core/client_ops.c.
921 * Fixed public key authentication from the client library.
922 Affected file lib/silcclient/protocol.c. Changed also the
923 protocol specification about the public key authentication in
924 the connection authentication protocol. The actual data to be
925 signed is now computed with a hash function before signing.
927 * Fixed the public key authentication from the server as well.
928 Affected file silcd/protocol.c.
930 * Removed the mlock()'s from the memory allocation routines.
931 Affected file lib/silcutil/silcmemory.c. The ./configure does
932 not check anymore for the mlock(). Affected file is
935 * Fixed USERS command in server to allow the execution of the
936 command for private and secret channels if the client sending
937 the command is on the channel. Affected file silcd/command.c.
939 * Fixed silc_client_get_clients_local to return the clients
940 count correctly. It could return wrong value. Affected file
941 lib/silcclient/idlist.c.
943 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
945 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
946 types. The assembler optimizations seemed not to like 64-bit
947 data types. The assmebler optimizations thus are now enabled
948 also for BSD systems as opposed to only enable them for Linux.
950 * Do not check for threads at all on BSD systems. Affected
951 file configure.in.pre.
953 * Removed -n and -h options from the Irssi SILC Client since
954 they are not used in silc.
956 * Fixed the prime generation to assure that the first digit
957 of the generated random number is not zero since our conversion
958 routines does not like number strings that starts with zero
959 digit. If zero digit is seen the random number is regenerated.
960 This caused some corrupted RSA keys when the zero first digit
961 was met. Affected file lib/silcmath/silcprimegen.c.
963 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
965 * Fixed WIN32 configuration in the ./configure script.
966 Fixed to include xti.h on environments that has it.
967 Patches by Carsten Ilchmann and andrew.
969 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Changed the silc_id_create_client_id to be collision
972 resistant. It is now assured that there cannot be created
973 two same client ID's. I suspect that some weird bugs in
974 the server were actually caused by duplicate Client IDs.
975 Affected file silcd/serverid.[ch]. A router receiving
976 new ID now also assures and informs the sending server
977 if the ID caused collision.
979 * Changed the silc_id_create_channel_id to also assure that
980 there are no collisions.
982 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Statement about ignoring the Mutual Authentication flag when
985 performing rekey with PFS was a bit misleading. It is ignored
986 if it was set in the initial negotiation, it cannot be even
987 set in the rekey. Fixed in the ke-auth draft. Started the
988 new versions of the protocol drafts in the doc/.
990 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Fixed a bug in silc_client_command_identify_save when saving
993 new channel information. The channel name was no duplicated
994 and caused crash on exit. Affected file is
995 lib/silcclient/command_reply.c.
997 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
999 * Fixed the getkey command handling in the server. Send just
1000 empty OK reply to the sender if the key could not be fetched
1001 (but everything else was ok, like the key just was not available).
1002 Changed the public key parameter to optional in the protocol
1003 specs so that empty OK reply can be sent. Affected file
1006 Added a message to Irssi SILC client to tell to user if the
1007 server did not return a public key.
1009 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * Fixed a channel key regeneration bug. It registered new
1012 timeout tasks exponentially until all system resources were
1013 used. Affected file silcd/server.c.
1015 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Added the SILC Document generator to the scripts/silcdoc.
1018 It can be used to generate the Toolkit Reference Manual out
1019 of the source tree. Internally it will also use the RoboDoc
1020 generator now imported in util/robodoc.
1022 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Added couple of return's in rekey protocol if error orccurred
1025 during the protocol. The execution must be terminated.
1026 Affected file silcd/protocol.c. Also, terminate the protocol
1027 always with timeout.
1029 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1031 * The client's Client ID was created initally from the wrong
1032 nickname (it could have been in format nick@host) in the
1033 silc_server_new_client. Affected file silcd/packet_receive.c
1035 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1037 * Added some SILC_LOG_ERROR's to various error conditions
1038 if client could not be added to ID cache. Affected files
1039 silcd/packet_receive.c and silcd/server.c.
1041 * When client's sock->user_data is freed, NULL also the
1042 client->router and client->connection pointers. Added check
1043 for these pointers being NULL to various places around the
1044 code. Affected file silcd/server.c.
1046 * Added client->data.registered == TRUE checks to various
1047 places around the code to assure that unregistered client's
1048 are not handled when it is not allowed. Affected file
1051 * Added `bool registered' fields to all
1052 silc_idlist_[server|client]_get_* routines to indicate whether
1053 the fetched client needs to be registered or not. Affected
1054 file silcd/idlist.[ch].
1056 * Add your own entry as registered to the ID cache in the
1057 server. Affected file server.c.
1059 * Fixed a bug in silc_server_new_server. The SilcServer was
1060 set as the new server's context instead of SilcServerEntry.
1061 This naturally caused some weird bugs.
1063 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1065 * Do not delete the channel rekey task when adding it
1066 for in silc_server_create_channel_key.
1068 * Changed the silc_server_create_channel_key to return
1069 TRUE or FALSE to indicate the success of the channel key
1072 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Fixed MSVC++ project files and added missing files to
1075 Makefiles under win32/.
1077 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1079 * Do not add TCP_NODELAY flag if the operating system
1080 does not have it defined. Affected files are
1081 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1083 * Fixed buffer overflow from Irssi SILC Client. Affected
1084 file irssi/src/fe-common/core/themes.c.
1086 * Fixed double free in client library in the file
1087 lib/silcclient/client.c when disconnecting from server.
1089 * Applied double free patch from cras to Irssi SILC client.
1090 Affected files irssi/src/core/[modules/expandos].c
1092 * Fixed the disconnection handling to Irssi SILC Client.
1093 The application must call silc_client_close_connection
1094 in ops->connect client operation in case of failure of
1095 the connection. Affected file is
1096 irssi/src/silc/core/client_ops.c.
1098 * Do not set sock->protocol to NULL in the function
1099 silc_client_close_connection after executing the protocol's
1100 final callback since the sock might not be valid anymore.
1101 Affected file lib/silcclient/client.c.
1103 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Do not enable SILC_THREADS if the linking with libpthread
1106 did not happen. Affected file configure.in.pre.
1108 * Added notion to protocol specification that server must
1109 verify the sent authentication payload with CMODE when
1110 setting the channel founder key. Implemented it to the
1111 server. Affected file silcd/command.c.
1113 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Added _EXTRA_DIST SILC distribution variable to the
1116 distributions file. It is used to conditionally add extra
1117 files or directories to the specific distribution. Affected
1118 files ./prepare, Makefile.am.pre and distributions.
1120 Removed the `_' from the start of the distribution names.
1123 * Added README.WIN32 for instructions to compile the Toolkit
1126 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1128 * Fixed a double free in disconnection in the server. Affected
1129 file is silcd/server.c.
1131 * Fixed the lib/silcske/groups.c to work now also with GMP
1132 MP library. The string conversion did not work when using
1133 specific base and the base is indicated in the string as well.
1135 * Created win32/ directory which now includes MSVC++ specific
1136 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1137 It will appear only in the toolkit distribution
1139 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Changed the key material distribution function in case when
1142 the hash output is too short. The data is now concatenated
1143 a bit differently than it used to. Made the change to the
1144 SKE protocol specification.
1146 * Added better GMP detection to configure.in.pre. A patch
1149 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * Fixed a minor bug in SKE that might cause some problem on
1152 some platforms. Affected file lib/silcske/silcske.c.
1154 * Added the cookie checking for initiator in the SKE. It checks
1155 that the responder returns the sent cookie unmodified. The
1156 affected file is lib/silcske/silcske.c. Added new SKE
1157 error type INVALID_COOKIE that can be sent during the
1158 negotiation. Fixed some memory leaks as well.
1160 * Added the "invalid cookie" error message to Irssi SILC client's
1163 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1165 * Added `task_max' field to the SilcClientParams to indicate
1166 the maximum tasks the scheduler can handle. If set to zero,
1167 default values are used. Affected file lib/silcclient/silcapi.h.
1169 * Fixed memory leaks in silc_client_close_connection. Affected
1170 file lib/silcclient/client.c.
1172 * Added silc_client_del_client_entry to client library to free
1173 all memory of given client entry. Affected file is
1174 lib/silcclient/idlist.[ch].
1176 * Added new functions silc_client_del_channel and
1177 silc_client_del_server to delete channel and server entries.
1178 Affected file lib/silcclient/[silcapi.h/idlist.c].
1180 * Removed silc_client_del_client_by_id from silcapi.h.
1182 * Fixed the INFO command to return the server's own info
1183 correctly when querying by Server ID. Affected file is
1186 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1188 * Removed the non-blocking settings in WIN32 code in the
1189 silc_sock_[read/write] and added SleepEx instead. Affected
1190 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1191 of input data is now checked with FIONREAD and ioctlsocket.
1193 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1195 * Call silc_schedule_task_del_by_context in the
1196 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1197 Affected file lib/silccore/silcprotocol.c.
1199 * Call silc_protocol_cancel for active protocols in the
1200 silc_server_close_connection if the funtion
1201 silc_server_free_sock_user_data has not been called.
1202 Affected file silcd/server.c.
1204 * Generic tasks cannot be deleted using the del_by_fd
1205 task deleting function since generic tasks does not match
1206 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1208 * Added a notion to SILCOPER help file that the SILCOPER works
1209 only on router server, not on normal server.
1211 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1213 * Added for WIN32 support for the new scheduler as well.
1214 Affected file lib/silcutil/win32/silcwin32schedule.c.
1216 * Fixed the SHA1 implementation to work on various platforms.
1218 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1220 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1221 API. It is part of the scheduler now. Everything else is
1222 as previously but some functions has changed their names.
1223 Checkout the lib/silcutil/silcschedule.h for the interface.
1224 Updated all applications to use the new interface. Affected
1225 files are lib/silcutil/silcschedule.[ch].
1227 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1229 * Found a bug in the SKE implementation. The HASH value,
1230 specified by the protocol, was not computed correctly. The
1231 public key of the responder was not added to the computation
1232 even though it is mandatory. Affected file lib/silcske/silcske.c.
1233 This unfortunately causes incompatibilities with older
1234 clients and servers.
1236 * Added WIN32 specific network init and uninit functions:
1237 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1238 the Winsock2. Affected file lib/silcutil/silcnet.h and
1239 lib/silcutil/win32/silcwin32net.c.
1241 * Set the socket always to nonblocking mode on WIN32 after
1242 reading data or writing data. Affected file is
1243 lib/silcutil/win32/silcwin32sockconn.c.
1245 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1247 * Fixed various compilation problems under WIN32. Affected
1248 files lib/silcutil/win32/silcwin32thread.c and
1249 lib/silcutil/win32/silcwin32schedule.c.
1251 * Removed all _internal.h #includes from public header
1252 files. Internal headers must never be included from
1255 Removed also the lib/silcske/payload_internal.h file.
1257 * All include files that may be needed (public and some others
1258 included by the public headers) by application developers are
1259 now copied to the ./includes directory. It does not copy any
1260 internal headers. Affected file Makefile.defines.pre and all
1261 Makefile.am's under lib/ and subdirs.
1263 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Do not change the ~/.silc directory's permissions automatically.
1266 Affected file irssi/src/silc/core/clientutil.c.
1268 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Do not cancel the protocol in silc_server_close_connection
1271 it might cause recursion. Now cancelled in the function
1272 silc_server_free_sock_user_data. Affected file silcd/server.c.
1274 * Fixed the silc_server_remove_clients_by_server to regenerate
1275 the channel keys correctly finally. Added also new function
1276 silc_server_remove_clients_channels to actually do it.
1277 Affected file silcd/server.c.
1279 * Fixed the silc_server_new_channel to not crash by giving
1280 wrong router to the new channel. Affected file is
1281 silcd/packet_receive.c.
1283 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1285 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1286 which is given as argument to the silc_client_alloc now.
1287 It can be used to configure the client and set various parameters
1288 that affect the function of the client.
1290 * The USERS command in server did not check whether the channel
1291 is private or secret. Affected file silcd/command.c.
1293 * Added new argument to the USERS command in protocol specification.
1294 The USERS command now can take the channel name as argument
1295 as well. Added support for this in client and server and
1296 updated the protocol specs.
1298 * Completed the GETKEY command in client. It can be now used
1299 to fetch also servers public key not only some clients.
1300 Affected files lib/silcclient/command[_reply].c.
1302 * Added silc_client_get_server to return server entry by the
1303 server name. Affected files lib/silcclient/silcapi.h and
1306 * Redefined the IDENTIFY command in protocol specification to be
1307 more generic. It now can be used to query information about
1308 any entity in the SILC Network, including clients, servers and
1309 channels. The query may be based either the entity's name
1310 or the ID. Added support for this in both client and server.
1312 Affected files silcd/command.c and lib/silcclient/command.c
1313 and command_reply.c.
1315 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1316 the _from_client and _from_server functions. Affected file
1319 * Added silc_client_get_channel_by_id_resolve to the file
1320 lib/silcclient/silcapi.h to resolve channel information by
1321 its ID. Added also silc_client_get_channel_by_id that
1322 does not resolve it from the server.
1324 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Added SilcServerEntry context into the client library
1327 to represent one server. The INFO command now allocates
1328 these to save the resolved server info. For now on the
1329 client library will also keep information about servers,
1330 connected and resolved with INFO.
1332 The INFO command now allocates the SilcServerEntry context
1333 and saves the server info there. The COMMAND_REPLY in
1334 the INFO now returns the parameters to application in
1335 same order as defined in the protocol specification.
1337 The entries are cached in the client->server_cache.
1339 * The INFO command is now issued after received the Client ID
1340 from the server. Affected file lib/silcclient/client.c.
1342 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1343 to the application as the mode changer might be server.
1344 It is guaranteed that NULL is not returned anymore to the
1345 application. Affected file lib/silcclient/client_notify.c.
1347 The ID Type is now also passed to the application so that
1348 it can check whether the returned entry is SilcClientEntry
1351 Added new function silc_client_get_server_by_id to return
1352 the server entry by ID. Affected files are the
1353 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1355 * Do not create the channel in the Irssi SILC Client when issuing
1356 the JOIN command but when received the sucessful JOIN command
1357 reply. Otherwise the channel might get created even though we
1358 could not join it. The Affected file is
1359 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1361 * Fixed a channel joining bug in router. The router must also
1362 check the channel modes, invite and ban lists etc. when serving
1363 the JOIN command sent by normal server. Affected file is
1364 silcd/command.c. The router now resolves the client's
1365 information from the server who sent the JOIN command if it
1366 does not know it, and processes the JOIN command only after
1369 * Changed the SilcCommandCb to take new argument; void *context2.
1370 Affected file lib/silccore/silccommand.h
1372 The second argument in the command callbacks in the server now
1373 includes the SilcServerCommandReplyContext if the command was
1374 called as pending command callback from the command reply.
1375 Otherwise it is NULL. When called as pending the status of the
1376 command reply will be checked and if it was erronous the
1377 error will be sent to the original sender of the command.
1378 This way the client always receives the error messages even
1379 though the server was actually the one who received the error
1380 when it resent the command to router, for example. Affected
1381 files silcd/command[_reply].[ch].
1383 * Fixed sending WHOWAS command's error message to client if
1384 the requested client could not be found. It was missing.
1387 * Changed the CMODE and CUMODE commands reply arguments in the
1388 protocol specification. The Channel ID is now sent in both
1389 of the commands to identify the channel. Implemented this
1390 new feature to the client and server. Affected files
1391 lib/silcclient/command_reply.c and silcd/command.c.
1393 * Made better checks for invite and ban lists in the JOIN
1394 command in server. Affected file silcd/command.c.
1396 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * The server now performs the incoming host IP/DNS lookup
1399 using the silc_socket_host_lookup and thus does not block
1400 the server anymore. Affected file silcd/server.c.
1402 * Completed the multi-thread support for SILC Scheduler in
1403 the lib/silcutil/silcschedule.c.
1405 * Fixed the configure.in.pre to detect the pthread correctly
1408 * Fixed a deadlock in silc_task_queue_wakeup in the file
1409 lib/silcutil/silctask.c.
1411 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Added new function silc_schedule_wakeup that is used in
1414 multi-threaded environment to wakeup the main thread's
1415 schduler. It needs to be used when a thread adds a new task
1416 or removes a task from task queues. After waking up, the
1417 scheduler will detect the task queue changes. If threads
1418 support is not compiled in this function has no effect.
1419 Implemented the wakeup mechanism to both Unix and WIN32
1420 systems. Affected files are lib/silcutil/silcschedule.[ch],
1421 lib/silcutil/unix/silcunixschedule.c and the
1422 lib/silcutil/win32/silcwin32schedule.c.
1424 * Added new function silc_task_queue_wakeup to wakeup the
1425 scheduler by the specified task queue. Affected file
1426 lib/silcutil/silctask.[ch].
1428 * The silc_socket_host_lookup_start now wakes up the scheduler
1429 after adding the timeout task. Affected file is
1430 lib/silcutil/silcsockconn.c.
1432 * The silc_socket_host_lookup is synchronous now if the threads
1433 support is not compiled in. However, the callback is still
1434 called asyncronously through the scheduler, anyway. Affected
1435 file lib/silcutil/silcsockconn.c.
1437 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Added new function silc_socket_host_lookup to perform
1440 asynchronous IP and FQDN lookups for the socket connection.
1441 Affected files lib/silcutil/silcsockconn.[ch].
1443 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1445 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1446 that may or may not compile the mutex support in.
1448 Changed the silc_mutex_alloc interface. It allocates the
1449 mutex now to the sent pointer and returns TRUE or FALSE.
1451 Affected file lib/silcutil/silcmutex.h.
1453 * Wrote the SILC Task Queue interface to support multi-threads.
1454 Affected file lib/silcutil/silctask.[ch].
1456 * Wrote the SILC Scheduler to support multi-threads. Affected
1457 file lib/silcutil/silcschedule.c.
1459 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1461 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1462 in lib/silcutil/win32/.
1464 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1466 * Defined SILC Mutex API and SILC Thread API and implemented
1467 them for Unix. Affected files are
1468 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1469 lib/silcutil/unix/silcunixmutex.c and
1470 lib/silcutil/unix/silcunixthread.c.
1472 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1474 * Fixed the silc_server_remove_clients_by_server's channel
1475 key re-generation. The hash table handling was incorrect
1476 and would not work with many channels. Affected file is
1479 * Fixed some memory leaks around the server code.
1481 * Rewrote the silc_server_get_users_on_channel to support IPv6
1482 based Client ID's. Affected file silcd/server.c.
1484 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1485 specification. However, a separate document must be written
1486 to define the detailed signing procedure and the payload
1487 associated with the flag. Defined the flag to the
1488 lib/silccore/silcchannel.h as well.
1490 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Changed the dynamic tables to static size tables in the
1493 lib/silccrypt/silchmac.c.
1495 * Removed GCC dependencies from the code. A patch by cras.
1497 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Do not show the error "Error receiving packet bla bla"
1500 in server if it really was not an error (-2 means that reading
1501 is pending). Affected file silcd/server.c.
1503 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed a possible crash in silc_server_remove_clients_by_server
1506 in silcd/server.c. Fixed there also some memory leaks.
1508 * Fixed the silc_idlist_replace_client_id. It could replace
1509 wrong key in the hash table. Affected file silcd/idlist.c.
1511 * Do not check whether there are global users on the channel
1512 if the channel->global_users is FALSE. Affected functions
1513 silc_server_remove_from_one_channel and
1514 silc_server_remove_from_channels in silcd/server.c. Also,
1515 do not check if the removed client is local as we can be
1516 sure that global client was not removed from the channel
1517 and checking for global users is not needed.
1519 * The silc_server_remove_clients_by_server now re-generates
1520 the channel keys correctly for those channels that had
1521 clients removed from them. Affected file silcd/server.c.
1523 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1525 * Found the reason of random crashes in the server. We weren't
1526 ignoring the SIGPIPE signal (which can be sent in write())
1527 and it crashed the server. Affected file silcd/silcd.c.
1529 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Assure that sock->user_data is not NULL in the function
1532 silc_server_packet_send in silcd/packet_send.c.
1534 * Disconnect the remote connection if it could not be added
1535 to any ID lists in the server. The affected file is
1538 * Check in silc_server_packet_send[_real/dest] that the
1539 socket is not disconnecting and ignore the data if it is.
1540 Affected file silcd/packet_send.c.
1542 * Define inline to __inline on native WIN32 compilation.
1543 Affected file includes/silcwin32.h.
1545 * Added some explicit type casts for inline code since MSVC
1546 require them. Affected files lib/silcutil/silcbuffer.h,
1547 lib/trq/silcdlist.h and lib/trq/silclist.h.
1549 * Print warning in log files from now on if the packet
1550 decryption fails. Affected file silcd/server.c.
1552 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Changed the `say' client operation's interface to accept
1555 new `type' argument to indicate the type of the message sent
1556 by the library. The application may filter the library's
1557 messages according the type. The affected file is the
1558 lib/silcclient/silcapi.h.
1560 * Added two new functions to lib/silcclient/silcapi.h:
1561 silc_client_del_client and silc_client_del_client_by_id.
1562 Affected file lib/silcclient/idlist.c.
1564 * Moved the clientincludes.h from includes/ to silc/ and
1565 serverincludes.h from includes/ to silcd/.
1567 * The modes for the CMODE and CUMODE are now passed as
1568 uint32 for application with COMMAND_REPLY. The affected
1569 file is lib/silcclient/command_reply.c.
1571 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * /WHOIS without arguments shows client's own information.
1574 Affected file lib/silcclient/command.c.
1576 * Changed PING to not accept any arguments. The specs
1577 says that client can ping only the connected server so
1578 requiring an argument is not needed. Affected file is
1579 lib/silcclient/command.c.
1581 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1583 * Fixed a fatal bug in private message sending and reception
1584 encryption and decryption when using private message keys.
1585 The implementation was incorrect and did not follow the
1586 specification. It causd that some of the message were
1587 lost since it did not use the sending and receiving keys
1588 as the protocol suggests. This has been fixed and will cause
1589 incompatibilities with older clients when sending private
1590 message encrypted with private message keys. Affected files
1591 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1592 and various other in Irssi SILC Client.
1594 Added `responder' boolean argument to the functions
1595 silc_client_add_private_message_key[_ske] to indicate when
1596 the key is added as responder or initiator of the key
1599 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Removed the silc_ske_check_version function and created
1602 a SilcSKECheckVersion callback. Added also a function
1603 silc_ske_set_callbacks that is now used to set all SKE
1604 callbacks. The callback functions are not given to
1605 the SKE functions anymore, but this function is used to
1608 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1610 * Added `silc_version' argument to the silc_client_alloc
1611 to define the version of the application for the library.
1612 The library will use the version string to compare it
1613 against the remote host's (usually a server) version
1614 string. Affected file lib/silcclient/silcapi.h
1616 * Added the KE protocol context to Key Agreement context
1617 in client library so that we can abort the SKE if it
1618 is in process when we get timeout. Affected file is
1619 lib/silcclient/client_keyagr.c.
1621 * Do not resolve the client ID forever if it returns in the
1622 first time that such client does not exist. This was done
1623 for example with private message. Affected file is
1624 lib/silcclient/client_prvmsg.c.
1626 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1628 * Do not add regex.h for WIN32. The affected file
1629 includes/silcincludes.h.
1631 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1632 not work yet 100%. It generates the DLL's automatically
1633 when compiling with --with-win32 under cygwin.
1635 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * lib/contrib/regex.c is not compiled on WIN32.
1639 * Added silc_net_get_socket_opt function to the
1640 lib/silcutil/silcnet.h.
1642 * Added includes/silcwin32.h for WIN32 specific includes
1645 * Do not use ptime structure or any of the posix process
1646 functions on WIN32 in lib/silccrypt/silrng.c.
1648 * Added silc_gettimeofday to provide generic function
1649 for struct timeval on all platforms. Added the function
1650 to lib/silcutil/silcutil.h.
1652 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1654 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1655 library as they clearly belong there. As a plus side we
1656 can make the actual socket connection routines platform
1659 Added also new generic function silc_socket_read and
1660 silc_socket_write (that used to be silc_packet_[read/write].
1661 The implementation of these are platform specific.
1663 * Added WIN32 specific routines of silc_socket_[read/write]
1664 to lib/silcutil/win32/silcwin32sockconn.c.
1666 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Added preliminary support for native WIN32 compilation under
1669 cygwin (using the -mno-cygwin option for GCC) to the
1670 ./configure.in.pre. The --with-win32 now prepares the
1671 compilation for native WIN32.
1673 * Rewrote the SILC Scheduler interface in the file
1674 lib/silcutil/silcschedule.h. The scheduler is now context
1675 based and does not have anymore any global static scheduler.
1676 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1677 and created lib/silcutil/win32 directory for WIN32 based
1680 * Added Unix specific network routines to the
1681 lib/silcutil/unix/silcunixnet.c and the old
1682 lib/silcutil/silcnet.c includes now only generic routines.
1684 Added WIN32 specific network routines to the
1685 lib/silcutil/win32/silcwin32net.c.
1687 * Added Unix specific utility functions from the
1688 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1690 * Added WIN32 SILC Scheduler to the file
1691 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1694 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Do not handle JOIN notify in the server if the target client
1697 is not registered (idata->registered == FALSE). The affected
1698 file is silcd/packet_receive.c.
1700 * Update the nickrec->founder in event_cumode in the Irssi SILC
1701 client. Affected file irssi/src/silc/core/silc-channels.c.
1703 * Fixed the CUMODE_CHANGE notify handling in the server when
1704 server and router are announcing their clients on channels.
1705 Now the mode changes are saved and notified correctly. The
1706 affected file is /silcd/packet_receive.c.
1708 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1709 They really did not replace the cache entry in the ID Cache.
1710 Now they do that. Affected file silcd/idlist.c.
1712 * Fixed the KICK notify handling in the Irssi SILC client to
1713 update the channel records so that the kicked client does not
1714 appear to be on the channel. The affected file is
1715 irssi/src/silc/core/silc-channels.c.
1717 * Always update the conn->current_channel when executing command
1718 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1720 * Fixed the KILL notify handling in Irssi SILC client to remove
1721 the killed client on all channels.
1723 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1725 * Fixed the silc_parse_command_line to remove extra spaces
1726 from the start and end of the arguments. Affected file is
1727 lib/silcutil/silcutil.c.
1729 * Cancel and free any active protocol in the function
1730 silc_server_close_connection. Affected file silcd/server.c.
1732 * Cancel and free any active protocol in the function
1733 silc_client_close_connction. Affected file is
1734 lib/silcclient/client.c.
1736 * Do not execute the KILL command for clients that are in
1737 history (ie. they are not in the network). Affected file is
1740 * Fixed KILL notify handling, client does not crash anymore.
1741 Affected file irssi/src/silc/core/silc-channels.c.
1743 * Reduced the default packet buffer size from 2048 to 1024 in
1744 lib/silccore/silcpacket.c.
1746 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1747 counter to the SKE context that is incresed when the SKE library
1748 performs async operation outside the library. If the outside
1749 process frees the SKE context and FREED status will be set
1750 and the library will detect after the sync operation that the
1751 libary is freed. The affected files are
1752 lib/silcske/silcske[_status].[ch].
1754 * Resolve the client entry information in the function
1755 silc_client_channel_message to assure that NULL pointer is not
1756 passed as client entry to the application. */
1758 * Fixed the task timeout calculation to assure that there is
1759 never negative timeouts. The affected file is
1760 lib/silcutil/silcschedule.c.
1762 * Fixed the channel user mode notification sending in server.
1763 It was sent point-to-point to the router (or to server by router)
1764 but it needs to be destined to a channel. The routines now
1765 supports sending the channel user mode notifys to the channels
1766 when announcing clients and channels. Affected files are
1767 silcd/server.c and silcd/packet_receive.c.
1769 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1770 It did not actually replace the old channel entry in the cache.
1771 Affected file lib/silcclient/client_notify.c.
1773 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1775 * Fixed a possible crash in silc_packet_send_prepare. It now
1776 assures always that there is enough space in the buffer and
1777 at the tail area of the buffer (for MAC).
1779 Fixed the inbound buffer reallocation in silc_packet_read.
1780 It was old code and did not handle the reallocation correctly.
1783 The affected file is lib/silccore/silcpacket.c.
1785 * Fixed buffer overflow in silc_parse_nickname in the file
1786 lib/silcutil/silcutil.c.
1788 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1790 * make install generates new server keys only if there is not
1793 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1795 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1796 Added check that if the NOREPLY is set then we will not send
1797 the away message. This avoids infinite loop of away messages
1798 if both clients are away. The affected file is
1799 lib/silcclient/client_prvmsg.c.
1801 * Fixed client crash if /NICK was given without arguments.
1802 Affected file lib/silcclient/command.c.
1804 * Server does not send the invite list in INVITE command back
1805 to the client if the list was not altered. Added this notion
1806 to the protocol spec as well. Affected file silcd/command.c.
1808 Fixed possible crash in INVITE command by checking the
1809 value of silc_server_get_client_route command.
1811 * Fixed the INVITE notify type handling. The arguments are now
1812 taken in correct order and client does not crash. The affected
1813 file is irssi/src/silc/core/silc-channels.c.
1815 Removed the "Inviting xxx to channel" message from the
1816 client library away and let the application handle it.
1817 Affected file lib/silcclient/command.c. Added that message
1818 to Irssi SILC client's message formats.
1820 * Fixed CMODE command crash in client. It now checks the
1821 amount of arguments correctly and does not crash. The affected
1822 file is lib/silcclient/command.c.
1824 * Do not create new channel automatically in silc_channels_join
1825 but check whether the channel by that name already exists.
1826 Affected file irssi/silc/core/silc-channels.c.
1828 * Do not send the SERVER_SIGNOFF to router if the disconnected
1829 entity was the router. Affected file silcd/server.c.
1831 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1832 SILC client as it was missing from there.
1834 Added the handling of the KICK notify to the Irssi SILC client
1835 as it was missing. Added "you have been kicked" message to
1836 Irssi SILC client's message modules formats.
1838 Added the handing of the KILL notify to the Irssi SILC client
1839 as it was missing. Added the kill message module formats
1842 The affected file is irssi/src/silc/core/silc-channels.c.
1844 * The router did not save the channel mode the server announced.
1845 Affected file silcd/packet_receive.c.
1847 * Fixed a possible crash in INFO command in server. If the
1848 server did not provide the server info it crashed. Affected
1849 file silcd/command.c.
1851 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1853 * Fixed the GETKEY command in the server to check also the
1854 global list. Otherwise the GETKEY would not work correctly
1855 in normal SILC server. Affected file silcd/command.c.
1857 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Fixed GETKEY crash, it crashed if the command did not succseed.
1861 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1863 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1864 is now real and not just an macro interface to GMP.
1866 Removed the entire GMP from the source tree and imported new
1867 NSS MPI library instead. Reason for removing GMP is that it is
1868 extremely large and compiles extremely slow. The NSS MPI
1869 is only a few files and compiles in less than 10 seconds.
1870 The speed is also about the same as GMP. The MPI is imported
1871 to lib/silcmath/mpi.
1873 If the system has GMP installed we will still use the GMP.
1874 If it is not then the NSS MPI will be compiled.
1876 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1878 * Merged a long nickname (127 characters long) crash bugfix from
1879 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1881 * Merged a freed memory reference bugfix from Irssi CVS tree.
1882 Affected file irssi/src/core/commands.c.
1884 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Added the server's public key sving and verification to the
1887 server when performing the SKE. This was missing and the
1888 remote server's (or router's) public key was accepted without
1889 checking whether we have it previously or trust it at all.
1890 Affected file silcd/protocol.c.
1892 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1894 * Check in the silc_server_timeout_remote if protocol is active
1895 and make sure that the protocol's final callback is called so
1896 that all memory if freed. Affected file silcd/server.c.
1898 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * silc_server_whois_send_reply crashed the server if the nickname
1901 was 127 characters long. Affected file silcd/command.c.
1903 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Added sanity check to the silc_server_new_client. If the hostname
1906 is provided inside username then check that the provided hostname
1907 really is the same as the resolved one. If the hostname was not
1908 resolved then check it from the public key. Affected file is
1909 silcd/packet_receive.c.
1911 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1912 if the server disconnected us and the connection is not valid
1913 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1915 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1916 the library to the lib/silcutil/silcutil.[ch].
1918 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Close log file after open. Affected file
1921 lib/silcutil/silclog.c.
1923 * Check whether sock == NULL in silc_client_send_packet and return
1924 if it is. Affected file lib/silcclient/silcclient.c.
1926 * Check rec->entry == NULL in the Irssi SILC Client before
1927 sending the channel message. Affecte file is
1928 irssi/src/silc/core/silc-servers.c.
1930 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Merged a splitted window bugfix from Irssi CVS tree. The
1933 affected file is irssi/src/fe-text/textbuffer-view.c.
1935 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1936 It did not print nickname.
1938 * Improved the distributions system a bit.
1940 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1943 irssi/src/fe-text/gui-window.c.
1945 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1946 to in-active server. The affected file is
1947 irssi/src/silc/core/client_ops.c.
1949 * Resolve the client in USERS command reply if the entry does
1950 not have username resolved. The affected file is
1951 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1952 command to WHOIS command to really resolve stuff. The USERS
1953 is not used any more in any critical section so WHOIS can
1954 be used even though it might be slower than IDENTIFY.
1956 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1959 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1961 * Changed the protocol API a bit more consistent in the
1962 lib/silccore/silcprotocol.[ch].
1964 * Changed the following headers to ROBODoc format:
1966 lib/silccore/silcpayload.h
1967 lib/silccore/silcprotocol.h
1968 lib/silccore/silcsockconn.h
1970 All core library headers are now formatted.
1972 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1974 * Fixed a bug in Irssi SILC client; do not show that you are
1975 server/router operator if you really are not. Affected file is
1976 irssi/src/silc/core/client_ops.c.
1978 * Renamed silc_command_free_payload to silc_command_payload_free.
1979 Affected file lib/silccore/silccommand.h
1981 * Added silcmath.h to include the prototoypes of various routines
1982 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1985 * Changed the following headers to ROBODoc format:
1987 lib/silccore/silcchannel.h
1988 lib/silccore/silccommand.h
1989 lib/silccore/silcid.h
1990 lib/silccore/silcidcache.h
1991 lib/silccore/silcmode.h
1992 lib/silccore/silcnotify.h
1993 lib/silccore/silcpacket.h
1994 lib/silcmath/silcmath.h
1996 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1998 * Added checking to the server code not to start the server if
1999 ciphers and stuff are not configured properly. Affected files
2000 silcd/serverconfig.[h] and silcd/server.c.
2002 * Changed the layout of the header files of the public interfaces
2003 in the SILC libraries. The new layout supports ROBODoc
2004 documentation tool (and some others) so that it is easy to create
2005 a library reference manual. All the other headers and source
2006 code must still follow the CodingStyle document. Also source
2007 code must not include these ROBODoc stuffs, only the headers.
2008 Furthermore, all public interface headers must now be named
2009 by using `silc' prefix, example: silcapi.h, silccipher.h.
2010 Some files were renamed due to this. All the other headers
2011 must not be used as public interfaces. I will update the
2012 CodingStyle document later. Changed following headers, so far:
2014 lib/silcclient/silcapi.h
2015 lib/silccore/silcauth.h
2016 lib/silccore/silcprivate.h
2017 lib/silccrypt/silcdh.h
2019 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Removed silc_client_packet_send_flush from the client library
2024 as it is not needed. Affected file lib/silcclient/client.[ch].
2026 * Added printing of message of unresolved authentication method
2027 to the Irssi SILC client. Added it to the module formats.
2028 Removed the same message from the client library.
2030 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Added new distribution feature, DISTLABEL. Every distribution
2033 can define own preprocessor label that can be used in the
2034 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2035 file distributions, acconfig.h.pre and prepare.
2037 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2039 * Added Makefile.defines_int to include the actual definitions
2040 for Makefile.defines.in. Tested the new distribution system,
2041 created distributions and tested installation.
2043 * Added AWAY message printing to the Irssi SILC client. Added
2044 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2046 * Added SCONNECT command to call the SILC's CONNECT command.
2047 Cannot use CONNECT directly since Irssi uses that internally.
2048 Affected file irssi/src/silc/core/silc-servers.c.
2050 Added ACTION local command. It is same as ME command but takes
2051 the channel as mandatory argument.
2053 Rewrote some of the Irssi's help files to suite for SILC
2056 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Added Makefile.defines[.in] that should for now on be included
2059 in all Makefile.am file in the source tree. That file includes
2060 all common compilation definitions for SILC source tree.
2062 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Minor changes to the ./prepare script to change the package
2065 name according the distribution name to the configure.in.
2067 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Created new distribution system. Added file `distributions'
2070 that defines all the distributions that can be created out of
2071 the SILC source tree. The ./prepare script now reads that
2072 file to determine how to prepare the distributions. The
2073 first argument to the ./prepare is the name of the distribution
2074 and second is the version of the distribution. If given
2075 without arguments it creates the default (toolkit) distribution
2076 with the default version (defined in ./prepare).
2078 All Makefile.am files that are subject to the distributions
2079 are now named as Makefile.am.pre. These are ./Makefile.am
2080 and lib/Makefile.am. Others may be changed later.
2082 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added invite list, ban list, some key management and connection
2085 error message printing to module formats in the Irssi SILC client.
2087 * Added new silc_client_set_away_message to set the away message
2088 that is back to the person who sent private message. The
2089 affected file lib/silcclient/silcapi.h and the
2090 lib/silcclient/client_prvmsg.c.
2092 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2094 * Fixed the private message sending in the Irssi SILC client,
2095 added local command KEY to the Irssi SILC client.
2097 Added key management and key agreement message formats to the
2098 irssi/src/fe-common/silc/module-formats.[ch].
2100 Added USERS (alias WHO) printing, server/router operator
2101 indication and LIST command printing to the module formats.
2103 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2105 * Fixed channel joining notify handling, cumode notify handling
2106 from Irssi SILC client.
2108 * Added SILC specific module-formats to the Irssi SILC client so
2109 that SILC specific message hilighting, colors etc is possible.
2110 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2112 Added channel mode, channel user mode, actions, notices,
2113 whois and whowas printing to the the module-formats.c.
2115 * Fixed a bug in channel deletion in the server. The channel
2116 is not left to the cache even if the channel founder auth mode
2117 is set when there are no users anymore on the channel. Affected
2118 file silcd/server.c.
2120 * The silc_net_localhost now resolves the entire hostname including
2121 the domain name. Affected file lib/silcutil/silcnet.c.
2123 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Changed the ask_passphrase client operation to be ascynchronous.
2126 It has now a completion callback and a context that the
2127 application must call after it has got the passphrase from
2128 the user. Affected files lib/silcclient/silcapi.h,
2129 lib/silcclient/protocol.c, lib/silcclient/command.c and
2132 Added SilcAskPassphrase callback that the application calls
2133 to deliver the passphrase to the library.
2135 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2136 The public key verification and especially a certificate
2137 verification is asynchronous procedure.
2139 Added new SILC_SKE_STATUS_PENDING status to indicate the
2140 request is pending and a callback will be called to finalize
2143 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2144 indicate that remote end did not send its public key (or
2145 certificate), even though we require it. Added check for this
2146 condition in the SKE. This was a security bug, now fixed.
2148 Defined new SilcSKEVerifyCbCompletion callback that is called
2149 when the verification process is completed.
2151 The affected files lib/silcske/silcske_status.h and
2152 lib/silcske/silcske.[ch].
2154 * Changed the verify_public_key client operation to be async
2155 as well. Defined SilcVerifyPublicKey callback that is used to
2156 indicate the success of the public key verification process.
2158 Changed the server and client to use the new async client
2161 * Changed the Irssi SILC client's internal scheduler to be called
2162 twice as many times as it used to be. As a result the client
2163 should be a bit faster now. Affected file is
2164 irssi/src/silc/core/silc-core.c.
2166 * Added support to Irssi SILC client of asynchronous public key
2167 verification and passphrase inquiry. Affected file is
2168 irssi/src/silc/core/silc-core.c.
2170 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Do not say "You have left channel %s" in client library.
2173 Moved it to the application. Affected files are
2174 lib/silcclient/command.c and silc/client_ops.c.
2176 * Fixed silc_client_get_clients. Command context was not
2177 duplicated and was freed memory in the callback. Affected
2178 file lib/silcclient/idlist.c.
2180 * Do not say "you are now talking..." on JOIN command in the
2181 client library. The appliation must handle it.
2183 * Do not say ".. changed topic to" in command reply in the
2184 client libary. The application must handle it.
2186 * Fixed TOPIC command sending in the client library.
2188 * Fixed a memory leak in silc_client_command_free in the file
2189 lib/silcclient/command.c.
2191 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Imported a modified version of Irssi client to the source tree.
2194 The Irssi will be used to create a new client called
2195 Irssi SILC. Imported to irssi/.
2197 Added silc_core_init_finish function to the Irssi. Affected
2198 file irssi/configure.in.
2200 A lot changes in the Makefile.ams around the irssi tree.
2202 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Do not rehash if the new size is same as the old size of the
2205 hash table, in the silc_hash_table_rehash*. The affected file
2206 lib/silcutil/silchashtable.c.
2208 * Replaced hash_table_del_by_context calls from the server
2209 (when channel->user_list and client->channels) to the
2210 hash_table_del as it is sufficient and faster.
2212 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Added silc_hash_table_list, silc_hash_table_get and the
2215 SilcHashTableList structure to provide an alternative way to
2216 traverse the hash table. The affected files are
2217 lib/silcutil/silchashtable.[ch].
2219 * Changed the server's idlist routines to use the hash table
2220 routines to optimize the code.
2222 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2224 * Replaced the client entry's `channel' list and channel entry's
2225 `user_list' list to hash tables for optimized lookup. Changed
2226 the code to use the hash table interface around the code.
2227 Affected file lib/silcd/idlist.[ch].
2229 * Added `auto_rehash' boolean argument to the function
2230 silc_hash_table_alloc to indicate whether the hash table should
2231 auto-rehash when it thinks is appropriate time. It will
2232 increase the hash table size if the there is twice as much
2233 entries in the table than the size of the table, and will
2234 decrease the size if there are twice as less entries than
2235 the size of the table.
2237 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2241 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * silc_idcache_purge_by_context deletes the entry now by context
2244 as it is supposed to do. Affected file lib/silccore/idcache.c.
2246 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2247 client is not anymore valid (WHOWAS givens the info) and not
2248 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2250 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2252 * Removed the `data' and `data_len' arguments from the ID Cache
2253 interfaces and added `name' argument. ID Cache does not handle
2254 anymore the binary data only a names associated with given ID.
2256 * When hashing a Client ID with silc_hash_id the entire ID is
2257 not hashed anymore, instead only the hash of the Client ID is
2258 hashed. This way we can access the Client ID from the cache
2259 with Client ID but with the hash of the ID (which is a hash of
2260 the nickname) as well without any difference in performance.
2262 Added also silc_idcache_find_by_id_one_ext to do one on one
2263 searching when we have the actual ID. Added also function
2264 silc_hash_client_id_compare. The affected files are
2265 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2267 * When hashing the name associated with a ID it is always done
2268 in lowercase. This way we can access the cache without worrying
2269 about case-sensitivity, even though, for example nicknames are
2272 * Fixed a bug in server with channel message sending. It put
2273 wrong ID type as destination ID. The affected file
2274 silcd/packet_send.c.
2276 * silc_idcache_del_by_context now deletes from all hash tables
2277 by context. Affected file lib/silccore/idcache.c.
2279 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Changed the client library to use the new ID Cache interface.
2282 Changes around the source tree.
2284 * Added silc_hash_table_rehash_ext to rehash with specific
2285 hash function. Affected file lib/silcutil/silchashtable.[ch].
2287 * Added silc_hash_string_compare to compare two strings in the
2288 hash table. Affected file lib/silcutil/silcutil.[ch].
2290 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Added new function silc_idcache_del_by_context into the
2293 lib/silccore/idcache.[ch].
2295 * Changed the server's ID list routines to use the new ID Cache
2296 interface. Changes around the source tree.
2298 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Added silc_hash_table_del[_by_context]_ext functions in to the
2301 lib/silcutil/silchashtable.[ch].
2303 Removed silc_hash_table_find_all* routines and added new
2304 silc_hash_table_find_foreach to replace them.
2306 Added silc_hash_table_replace_ext function as extended
2307 replacing function. Separated the simple hash table interface
2308 from the extended hash table interface in the file
2309 lib/silcutil/silchashtable.h.
2311 * Fixed minor bugs and changed it to use some of the new
2312 hash table functions in lib/silccore/idcache.c
2314 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Added new function silc_hash_table_find_all to return all keys
2317 in the hash table by the specified key. As the hash table is
2318 collision resistant it also makes it possible to have several
2319 duplicate keys in the hash table. This function may be used to
2320 find all of the keys from the hash.
2322 Added user_context arguments to the SilcHashFunction,
2323 SilcHashCompare and SilcHashDestructor to deliver user specified
2326 Added new fuctions silc_hash_table_find[_all]_ext to do
2327 extended lookup with specified hash and compare functions and
2328 specified user contexts.
2330 Added new function silc_hash_table_add_ext to add the key
2331 with specified hash function and user context.
2333 Added new function silc_hash_table_foreach to traverse all
2334 entrys in the hash table. Added SilcHashForeach callback
2337 Added new function silc_hash_table_del_by_context to delete
2338 the entry only if the context associated with the key matches.
2340 Affected files are lib/silcutil/silchashtable.[ch].
2342 * Removed silc_hash_[server/client/channel]_id and added just
2343 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2344 silc_hash_id_compare to compare two ID's using as the hash table
2345 comparison function. Added also silc_hash_data to hash
2346 binary data and silc_hash_data_compare to compare it.
2348 * Removed silc_idlist_find_client_by_hash as it is not needed
2349 anymore. Affected file silcd/idlist.[ch].
2351 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2352 to use internally the SilcHashTable. The new ID Cache is a lot
2353 faster than the old one. Some of the ID Cache interface was also
2354 rewritten and obsolete and stupid functions were removed.
2356 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Added entry_count field to the SilcHashTable to keep the number
2359 of the entries in the table. Implemented the function
2360 silc_hash_table_rehash. Added new function
2361 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2363 Fixed a minor bug in silc_hash_table_free.
2365 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2366 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2367 into the lib/silcutil/silcutil.[ch].
2369 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Implemented a collision resistant hash table into the
2372 lib/silcutil/silchashtable[ch]. See the header and the source
2373 for the SilcHashTable API.
2375 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2377 * Merged dotconf version 1.0.2 into lib/dotconf.
2379 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2381 * Do not compile anything in lib/silcsim/* if the SIM support
2382 is not enabled. The tree should now compile without problems
2385 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2387 * Compiled the SILC under cygwin. Compiled and tested briefly
2388 without problems. More tests needed. The SIMs didn't compile
2391 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2393 * Fixed possible crash in silc_get_username in the
2394 lib/silcutil/silcutil.c.
2396 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Fixed a va_arg in silc/client_ops.c.
2400 * Oops, RC5 routines were named AES and caused some problems
2401 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2403 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2405 * Added new SilcIDIP structure into the lib/silccore/id.h and
2406 replaced the old `ip' fields from all SILC ID's to that type.
2407 This is a step towards IPv6 support.
2409 The silc_id_get_len takes now the ID as an extra argument.
2410 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2411 both IPv4 and IPv6 based ID's.
2413 The affected files are lib/silccore/id.[ch] and other files
2414 around the tree using these routines.
2416 * Removed the ID length arguments in server from various
2417 silc_server_send_notify_* routines -> they are not needed
2420 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2422 * Fixed memory leak in silc_encode_pem_file in the file
2423 lib/silcutil/silcutil.c.
2425 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2427 * Check minor version as well in the SKE. Affected files are
2428 silcd/protocol.c and lib/silcclient/protocol.c.
2430 * Added --identifier option to the server so that an identifier
2431 can be when creating the public key for the server. Affected
2432 file is silcd/silcd.c.
2434 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2435 lib/silccrypt/silcpkcs.c.
2437 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2439 * Register default ciphers and stuff when using -C option with
2440 the server. Affected file sildc/silcd.c.
2442 * Put back the servers public key filename format, it is better
2443 than the new one. For now, the client keys are saved with the
2444 new filename format. The affected file silc/client_ops.c.
2446 * Implemented the Cipher API for the rest of the ciphers that
2447 did not implement it or implemented it the wrong way.
2449 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2451 * Register default ciphers and stuff when using the -S option
2452 in the client. Affected file silc/silc.c. Same also when
2453 creating new key pair with -C option.
2455 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Fixed the silc_verify_public_key client operation function to
2458 save the public keys differently. The fingerprint is now
2459 used as filename and not the hostname. This way also the
2460 client keys are saved uniquely and not with hostnames. The
2461 affected file is silc/client_ops.c.
2463 * Trimmed the silc_hash_fingerprint function to remove extra
2464 whitespaces from the end of the fingerprint. The affected
2465 file is lib/silccrypt/silchash.c.
2469 * Added silc_cipher_register_default function to register all
2470 default ciphers. It can be used when configuration files
2471 does not exist and the application does not want any specific
2472 ciphers in any specific order.
2474 The SilcDList is now used as silc_cipher_list dynamically
2475 allocated cipher list. Removed the static list all together
2476 and now all ciphers must be allocated to the dynamic list.
2477 The silc_cipher_alloc routine was changed to check only the
2480 All silc_cipher_* routines that used to return int returns
2483 The affected files lib/silccrypt/silccrypt.[ch].
2485 * The same thing was done to silc_hash_* as for silc_cipher_*
2486 routines. Affected files lib/silccrypt/silchash.[ch].
2488 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2489 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2490 Added also silc_pkcs_[un]register[_default] functions.
2491 Removed the data_context from the PKCS API.
2493 * Added silc_hmac_register_default function to register default
2494 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2495 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2496 to unregister all hmacs at once.
2498 * Register the default ciphers, hash functions, PKCSs and HMACs
2499 if client's configuration file does not exist. The affected
2502 * The client did not load the hash functions from the SIM
2503 modules at all. Added support for this. Affected file is
2504 silc/clientconfig.c.
2506 * When decoding public key with silc_pkcs_public_key_decode, check
2507 the supported algorithm only if PKCS are registered. Affected
2508 file lib/silccrypt/silcpkcs.c. The same was done with the
2509 silc_pkcs_private_key_decode.
2511 * Fixed the SILC List routines to keep the list always in order.
2512 It used to change the list's order when traversing the list but
2513 not it preserves the order. Affected file lib/trq/silclist.h.
2515 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added the client library to use the SilcSocketConnection's
2518 reference counter (by silc_socket_dup) to prevent the bug that
2519 the socket object may be freed underneath async operation.
2521 * The name resolv library checking fixes in the configure.in.pre.
2524 * Created new version of the protocol drafts for future
2525 development. The -03 drafts are the ones that will be changed
2526 in the trunk now and the -02 will remain as they are.
2528 * Send list of CUMODE notifys to the router when announcing
2529 the channel users to the router. Affected file silcd/server.c.
2530 If the router receiving channel founder CUMODE for a channel
2531 that already has channel founder it will send CUMODE notify
2532 to the sender to remove the channel founder rights from the
2533 announced client. Affected file silcd/packet_receive.c.
2535 * The CUMODE notify may now use Server ID as well as the entity
2536 who changes the mode. Updated protocool specs.
2538 * Updated INSTALL and README files.
2540 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * New web pages in the http://silc.pspt.fi. The pages was
2547 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2549 * Implemented the [DenyConnectin] config section in the server.
2550 Added silc_server_config_denied_conn to check whether incoming
2551 connection is denied. Affected file silcd/serverconfig.[ch].
2553 * Do not check the ports when checking the incoming configuration
2554 data if the port is 0, meaning any. Affected file is
2555 silcd/serverconfig.c.
2557 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2559 * Fixed buffer overflow in silc_string_compare in the file
2560 lib/silcutil/silcutil.c.
2562 * Fixed double free in silc_server_command_leave in the file
2565 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2567 * Fixed the version checking in the server. Affected file is
2570 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Fixed the configuration data fetching when accepting new
2573 connections in the server. Affected file silcd/server.c.
2575 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Added `sender_entry' argument to the function
2578 silc_server_packet_relay_to_channel so that we can check
2579 whether some destination actually belongs to the same route
2580 the sender belongs (ie, we must not resend the packet to the
2581 sender). Affected file silcd/packet_send.[ch].
2583 * Added `servername' field to the SilcClientEntry in the server
2584 to hold the name of the server where client is from. Affected
2585 file is silcd/idlist.h.
2587 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Moved the channel message encrypting in the router betwen
2590 router connections from silc_server_channel_message to the
2591 silc_server_packet_relay_to_channel since we want to check
2592 whether we have anybody channel before encrypting anything.
2593 Affected files silcd/packet_[receive/send].c.
2595 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2597 * Fixed the [AdminConnection] server config section to support
2598 multiple entries. Affected file silcd/serverconfig.c.
2600 * Added support into the server to check the validity of the
2601 incoming connection before executing any KE or authentication
2604 * The connection configuration is now saved to the KE and
2605 connection auth protocol contexts and not fetched anymore in
2606 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2608 * The local hosts listenning address and port is also resolved
2609 now when starting the server. We want to have the socket object
2610 to include the real address and port for the listener. Added
2611 new function silc_net_check_local_by_sock into the files
2612 lib/silcutil/silcnet.[ch].
2614 * Fixed a broadcast bug in server -> do not broadcast if we
2617 * Fixed a routing bug. Do not route broadcast packets ever.
2618 Broadcast packets must be processed always and not routed since
2619 they may be destined to some other host than yourself and thus
2620 would get routed without no good reason. Affected file is
2623 * Added function silc_server_config_is_primary_route to check
2624 whether primary router connection has been configured (a router
2625 configuration that we are initiating). If there is not, we
2626 will assume that there is only two routers in the SILC network
2627 and we will use the incoming router connection as our primary
2628 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2630 * Changed the order of the broadcasting. Broadcast _after_ the
2631 packet has been processed not before. Affected file is
2634 * Fixed a [ClientConnection] parsing bug. The port was never
2635 parsed correctly thus resulting to port 0. Affected file
2636 silcd/serverconfig.c.
2638 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2639 argument and did not set the broadcast packet flag. Affected
2640 file silcd/packet_send.c. Fixed same bug in the function
2641 silc_server_send_notify as well.
2643 * If we receive NEW_ID packet for our own ID in the server, ignore
2646 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2650 * Removed the nickname from the Private Message Payload.
2651 Updated the code and the protocol specs.
2653 * Updated protocol specs for submitting to the IETF.
2655 * Tweaked the Random Number Generator a bit. Affected file
2656 lib/silccrypt/silcrng.c. Exported a new function
2657 silc_rng_[global]_add_noise which can be used to add more
2660 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2662 * Do not parse packets with different timeout when protocol
2663 is active -> may cause problem with rekey. Affected file
2666 * When server receives signoff notify it must not create
2667 new channel key if the client is on any channels since the
2668 sender of the signoff notify will create it.
2670 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Added printing of error messages during SKE protocol from the
2673 failure packet sent by server during SKE. Affected file
2676 * Removed the client's failure_callback handling with timeout
2677 and handle it immediately when received.
2679 * The SKE library returned wrong type in SUCCESS and FAILURE
2680 packets. They must be 32 bit MSB not 16 bit MSB.
2682 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2684 * Ok, rewrote the logic of the re-key and now it seems to work.
2685 I tested it on high traffic with frequent re-keys without
2686 problems. Added hmac_receive (and renamed hmac to hmac_send)
2687 in SilcClientConnection in lib/silcclient/client.h and
2688 in SilcIDListData in silcd/idlist.h. Also, removed the
2689 SilcPacketParserContext's cipher and hmac fields as they are
2690 not needed anymore and actually caused some problems when
2691 the ciphers and hmac's changed underneath the packet parser.
2693 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2695 * If re-key protocol is active then process the incoming packets
2696 synchronously since we must assure that icoming packets encrypted
2697 with the old key is processed before the new keys is set to
2698 use. This is true other packets than for REKEY packets.
2699 Affected file silcd/server.c. The same was done to client library
2700 as well, affected file lib/silcclient/client.c.
2702 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2704 * Fixed bug in client and server to accept the force send if
2705 the packet is send from silc_[server/client]_packet_process
2706 function. Otherwise the packets are never delivered, oops.
2708 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Disable force sending of packets when REKEY protocol is active.
2711 We must assure that no packet is sent directly when rekey is
2712 performed. All packets must be sent through packet queue.
2713 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2714 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2715 function is silc_[server/client]_packet_send_real to check
2718 * Replaced the SIM paths from example config files to
2719 /usr/local/modules. Also, make install creates now
2720 /usr/local/silc/logs directory to hold all the SILC server
2723 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Made the configure.in.pre work on Solaris. Patch by salo.
2727 * Made all ciphers compatible with non-x86 machines. Defined
2728 CBC mode macros into lib/silccrypt/ciphers_def.h.
2730 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2732 * Fixed the make install.
2734 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2736 * When MAC computation fails the silc_packet_decrypt returned 0
2737 even though it was supposed to return -1. Fixed this. The
2738 affected file is lib/silccore/silcpacket.c.
2740 * Do not replace the config files in /etc/silc (in make install)
2741 if they already exist. Affected file ./Makefile.am.
2743 * Do not send re-key packets immediately but through packet queue.
2744 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2746 * Changed silc_net_check_host_by_sock to return FALSE if the
2747 IP/DNS could not be resolved. Though, it returns the IP address
2748 now even if it could not resolve it (but returns also FALSE).
2749 Affected file lib/silcutil/silcnet.[ch].
2751 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Added silc_pkcs_decode_identifier to decode the public key's
2754 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2755 Added also silc_pkcs_free_identifier. Added also new context
2756 SilcPublicKeyIdentifier.
2758 * Added -S option to the silc client. It is used to dump the
2759 contents of the specified public key file.
2761 * Changed the PKCS api to return the public key length when
2762 setting the public key.
2764 * Fixed a fatal bug in the public and private key file loading.
2765 Affected file lib/silccrypt/silcpkcs.c.
2767 * Execute the packet parsing for client with zero (0) timeout
2768 if the protocol is active. Affected file silcd/server.c.
2770 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Made the key generation options to the silcd program. Added
2773 -C option, equivalent to client's option.
2775 * Added new [ServerKeys] config section to the server. It
2776 configures the server's public and private key.
2778 * Defined generic Public Key Payload into the protocol
2779 specification to send specific type of public keys and
2782 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2783 public key or certificate.
2785 * Implemented the GETKEY command to the server and to the
2786 client library and on user interface.
2788 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Made preliminary `make install' work.
2792 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2794 * Added SilcServerRekey context into silcd/idlist.h.
2796 * Added the PFS support as defined in the specification to the
2797 SKE protocol. Affected files lib/silcske/*.c.
2799 * Added `ske_group' field to the SilcServerRekey context to hold
2800 the number of the SKE group that is used with PFS in re-key.
2801 Affected file silcd/idlist.h.
2803 * Added PFS re-key support to the server. Affected file is
2806 * Added silc_protocol_cancel to cancel execution of the next
2807 state of the protocol. Affected file is
2808 lib/silccore/silcprotocol.[ch].
2810 * Added the re-key support with and without PFS to the client
2811 library. Re-key is performed once in an hour, by default.
2813 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2814 Added silc_client_rekey_callback and silc_client_rekey_final.
2815 Affected files are lib/silcclient/protocol.[ch] and
2816 lib/silcclient/client.[ch].
2818 * Removed the `hmac_key' and `hmac_key_len' fields from the
2819 SilcClientConnection structure; not needed. Affected file is
2820 lib/silcclient/client.h.
2824 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Do not ask whether user wants to use the negotiated private key
2827 for private messages, just use it. Affected file is
2828 silc/local_command.c.
2830 * Added `send_enc_key' and `enc_key_len' fields to the
2831 SilcIDListData structure since they are needed in the re-key
2832 phase. Affected file is silcd/idlist.[ch].
2834 * Implemented the simple re-key protocol into the server.
2835 Affected files silcd/server.c and silcd/protocol.[ch]. The
2836 re-key will be performed once in an hour, by default.
2838 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2839 Added silc_server_rekey, silc_server_rekey_callback and
2840 silc_server_rekey_final.
2842 * Removed Tunneled flag from the protocol. Updated the code
2843 and the specifications.
2845 * Adde `pfs' field to the SilcIDListData to indicate whether
2846 the PFS is to be performed in the re-key. Affected file is
2849 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2852 int64 of at least the xintXX size. If void * is less that 4
2853 bytes uint32 * will be used. Defined bool as boolean.
2855 * Changed _ALL_ unsigned long and unsigned int to uint32,
2856 unsgined short to uint16 in the source tree.
2858 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2859 not handle clients that has entry->data.registered == FALSE.
2860 They are not in the network anymore. Affected file is
2863 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * Implemented the sending of the SERVER_SIGNOFF notify in the
2866 server. Affected file is silcd/server.c.
2868 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2869 Added also silc_notify_payload_encode_args into the
2870 lib/silccore/silcnotify.[ch].
2872 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2873 Affected file silcd/packet_receive.c.
2875 * Implemented the SERVER_SIGNOFF notify handling in the client
2876 library. Affected file lib/silcclient/client_notify.c. Also,
2877 implemnted the printing of the SERVER_SIGNOFF info to the
2878 application. Affected file silc/client_ops.c.
2880 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2881 if the deleting was successful. Affected file silcd/idlist.[ch].
2883 * Added support for public key authentication in the connection
2884 authentication protocol in the client library. Affected file
2885 lib/silcclient/protocol.c.
2887 * Changed the server's silc_idlist_get_clients_by_* interface
2888 to support already allocated array so that new entries may be
2889 added to pre-allocated array. Affected file silcd/idlist.[ch].
2890 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2891 and command replies.
2893 * All command reply functions in the server now calls the
2894 pending command callback even if error occured. This way the
2895 error will be delivered to the client as well. Affected files
2896 silcd/command.c and silcd/command_reply.c.
2898 * Fixed INFO command to return local server's info if no server
2899 was provided. Affected file lib/silcclient/command.c.
2901 * Removed RESTART command for good. Updated the code and the
2904 * Rewrote parts of the task system. It is a bit simpler now.
2905 Removed unsued task priorities. The affected files are
2906 lib/silcutil/silctask.[ch].
2908 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2910 * Moved the USERS printing from the library to the application.
2911 Affected files lib/silcclient/command.c and silc/client_ops.c.
2913 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2917 * Added channel key re-key support. The re-key is perfomed
2918 only by the router and is done once in an hour. Added `rekey'
2919 field to the SilcChannelEntry in the server. Affected files
2920 silcd/server.c and silcd/idlist.h.
2922 * Added silc_task_unregister_by_context into the file
2923 lib/silcutil/silctask.[ch].
2925 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2927 * Added SILC_UMODE_GONE mode to indicate when the client is not
2928 present in the SILC network. Added also support to the local
2929 command AWAY that will set this mode. Added support of showing
2930 "xxx is gone" in WHOIS command. The USERS command shows the
2931 gone status as well.
2933 * Fixed setting server and router operator privileges in the
2934 server's UMODE command. Affected file silcd/command.c.
2936 * Merged the SKE KE1 and KE2 payloads into one payload. The
2937 new KE payload is equivalent to the old KE2 payload.
2939 Cleaned up the SKE Start Payload parsing. It now uses the
2940 simple buffer unformatting to do the parsing. A lot faster
2943 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2944 to the SKE that is used to indicate whether both of the SKE
2945 parties should perform authentication. By default only the
2946 responder performs authentication. By setting this flag also
2947 the initiator must do authentication. By default it is unset
2948 since in normal SKE case, client to server connection, only
2949 the responder should do authentication. When doing SKE between
2950 two clients both should perform authentication. Updated the
2951 code and the protocol specs.
2953 * A little fix to IDENTIFY command in the server. Search the
2954 client first by hash not nickname. Affected file is
2957 * Fixed the silc_client_close_connection to support closing
2958 the client to client connections wihtout deleting too much
2959 data. Affected file lib/silcclient/client.c.
2961 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2962 are received if protocol used to be active but is not anymore
2963 the application would crash due to NULL pointer dereference.
2964 Affected files silcd/server.c and lib/silcclient/client.c.
2966 * Added `hash' field to the SilcClientConnection to include
2967 the hash function negotiated in the SKE protocol.
2969 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2970 to set the channel founder authentication data. A client can
2971 claim the founder rights later by providing the authentication
2972 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2973 This way the channel founder can regain the channel founder
2974 privileges even it is left the channel. This works only on
2975 local server and the client must be connected to the same
2976 server to be able to regain the founder rights. Updated the
2977 protocol specs accordingly.
2979 Added support to the CMODE command in the client to set the
2980 founder auth data. Read the README to see how to set it.
2982 Added support to the CUMODE command to claim the founder
2983 rights. Read the README to see how to do it.
2985 Added support for the founder authentication to the Channel
2986 Entry in the server. Affected file silcd/idlist.h.
2988 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2989 server's CMODE command. Affected file silcd/command.c.
2991 * Added the following new functions into lib/silccore/silcauth.[ch]:
2992 silc_auth_get_method and silc_auth_get_data.
2994 * The server now saves the remote hosts public key to the
2995 SilcIDListData pointer. Affected file silcd/protocol.c.
2997 * The normal server now does not remove the channel entry from
2998 the cache if the founder authentication data is set. It used
2999 to remove it if the founder was the last one on the channel on
3000 the server and left the channel. The auth data is saved and
3001 if the channel is re-joined later the old entry is used with
3002 the old auth data. Affected files silcd/command_reply.c and
3005 * Removed the `pkcs' field from the SilcIDListData structure
3006 in the server; it is not used. Affected file silcd/idlist.h.
3008 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3010 * Fixed packet processing on slow links. Partial packets were
3011 never re-processed because the incoming data buffer was cleared
3012 by the application. Application must not directly clear the
3013 sock->inbuf, the packet processing routines handle it. Fixed
3014 this in client library and in server.
3016 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3018 * Fixed the WHOIS and IDENTIFY send reply function to really
3019 check whether to send list or just one entry. Affected file
3022 * Cleaned up the LEAVE command's channel key distribution. The
3023 affected file silcd/command.c.
3025 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3026 can enforce the channel mode as well. In that case the ID
3027 includes the ID of the server. The code now enforces the
3028 mode change if the router have different mode than the server.
3030 * The notify client operation with CMODE_CHANGE notify can now
3031 return NULL client_entry pointer if the CMODE was not changed
3032 by client. Application must check for this.
3034 * Added <Server ID> argument to INFO command to support server
3035 info fetching by Server ID.
3037 * Added silc_server_announce_get_channel_users to get assembled
3038 packets of channel users of the specified channel. Affected
3039 file silcd/server.[ch].
3041 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3042 was freed underneath the ID Cache.
3044 * Re-announce clients when the server received CHANNEL_CHANGE
3045 notify from the router. Affected file silcd/packet_send.c.
3047 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3050 crashed since it did not handle the fact that there is no cipher
3051 called "3" and didn't check the error condition. Now fixed.
3053 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3054 flag. It can be used to send message requests.
3056 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Implemented the RESTART command in the client.
3060 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3061 notice type messages. Added notice printing to the user
3064 * The channel keys are not re-generated if the channel's mode
3065 is PRIVKEY, ie private key on the channel exists. Affected
3066 files silcd/server.c and silcd/command.c.
3068 * Fixed a little bug in channel message delivery when channel
3069 private keys are set in the server. Affected file is
3070 silcd/packet_send.c.
3072 * Changed the setting on channel->on_channel = TRUE from the
3073 silc_client_save_channel_key to the JOIN command reply. The
3074 key payload is not received if the private channel key is set.
3075 Affected file lib/silcclient/command_reply.c and the
3076 lib/silcclient/client_channel.c.
3078 * When the CMODE_CHANGE notify is sent and the channel private
3079 key mode is removed the channel key must be re-generated in
3080 other cells as well. Added this support for the router in the
3081 silcd/packet_receive.c.
3083 * Added new local command NOTICE to send notice message on
3084 channel. Affected file silc/local_command.[ch].
3086 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3088 * Added new local command ME to the client. It is used to send
3089 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3090 some action. Affected file silc/local_command.[ch].
3092 * Changed channel_message and private_message client operations
3093 to deliver the message flags to the application. Added also
3094 the `flags' arguments to the silc_client_send_channel_message
3095 and silc_client_send_private_message functions. Affected file
3098 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3100 * Redefined the Private Message Payload to support private message
3101 keys and to support the new private message flags. Updated
3102 the protocol specs. Flags makes it possible to have for example
3103 CTCP style messages.
3105 * Added new type SilcPrivateMessagePayload and defined an API
3106 for it in the lib/silcclient/silcprivate.[ch].
3108 * Tested private message private keys successfully. Tested the
3109 private message key set, unset and list commands with the new
3112 * Redefined the Channel Message Payload to include the channel
3113 message flags (equal with private message flags) to support
3114 for example CTCP style messages.
3116 * Defined some of the message (for channel and private message)
3117 flags. Updated the protocol specs and added the flags to the
3118 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3120 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3122 * Added SilcKeyAgreementStatus type to the key agreement routines
3123 to indicate the current status and error if one occured.
3124 The status types are defined in the lib/silcclient/silcapi.h.
3126 * Added new local command KEY that is used to set and unset private
3127 keys for channels, set and unset private keys for private messages
3128 with remote clients and to send key agreement requests and
3129 negotiate the key agreement protocol with remote client. The
3130 key agreement is supported only to negotiate private message keys,
3131 it currently cannot be used to negotiate private keys for channels,
3132 as it is not convenient for that purpose.
3134 * Fixed a minor pending callback setting bug in the function
3135 silc_client_get_client_by_id_resolve, now the function works.
3136 Affected file lib/silcclient/idlist.c.
3138 * Added function silc_net_get_local_port to get local bound
3139 port by socket. Added to lib/silcutil/silcnet.[ch].
3141 * Added `sockets' and `sockets_count' fields to the SilcClient
3142 object. They hold the sockets of the listenning sockets in
3143 the client. Listenning sockets may be for example the key
3144 agreement server. Affected file lib/silcclient/client.[ch].
3145 Added functions the silc_client_add_socket and the
3146 silc_client_del_socket. They are exported to the application
3149 * Added ~./silc/clientkeys to support other client's public keys.
3151 * Renamed verify_server_key client operation to verify_public_key
3152 and added one argument to indicate the type of the connection
3153 (server, client etc.).
3155 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Added silc_server_connection_auth_request to handle the
3158 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3159 silcd/packet_receive.[ch].
3161 * Added silc_server_send_connection_auth_request into the
3162 silcd/packet_send.c to send the connection auth request packet.
3164 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3167 * Fixed the public key authentication in responder side in the
3168 server. The `auth_data' pointer includes the SilcPublicKey
3169 not the path to the public key. Affected file silcd/protocol.c.
3171 * Implemented the public key authentication in the initiator side
3172 in the server. Affected file silcd/protocol.c.
3174 * Removed the [RedirectClient] config section from the server
3175 configuration. Is not needed and I don't want to implement it.
3177 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Cleaned up the CMODE command in the server. It now works
3180 correctly and supports all the modes defined in the protocol.
3181 Affected file is silcd/command.c.
3183 * Added `hmac_name' field to the SilcChannelEntry in the server
3184 to hold the default HMAC of the channel. It can be set when
3185 creating the channel (with JOIN command). Affected files
3188 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3189 type to indicate the change of the current cipher and hmac
3190 on the channel. Client can safely ignore the <cipher> argument
3191 (if it chooses to do so) since the CHANNEL_KEY packet will
3192 force the channel key change anyway. The <hmac> argument is
3193 important since the client is responsible of setting the new
3194 HMAC and the hmac key into use.
3196 * Fixed the CMODE command in the client library as well.
3198 * Tested CMODE command in router environment successfully.
3200 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Show the version of the remote client (or server) when connecting
3203 to the server. It is logged to the log file. Affected file
3204 is silcd/protocol.c.
3206 * Fixed the KILLED notify handling in the client library. The
3207 client must be removed from all channels when receiving the
3210 Also, do not remove the client entry when giving the KILL
3211 command but when the KILLED notify is received.
3213 * Removed silc_idlist_find_client_by_nickname from the server.
3214 Not needed anymore. Affected files silcd/idlist.[ch].
3216 * Implemented the CHANNEL_CHANGE notify type handling to the
3217 server. Affected file silcd/server.c.
3221 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3224 notify between routers.
3226 * Implemented the INVITE command correctly to the server.
3228 * Implemented the INVITE notify type handling in the server.
3230 * Implemented the INVITE command to the client library and on the
3233 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3235 * Added function silc_server_get_client_resolve to find the
3236 client entry by ID from all ID lists and then resolve it
3237 (using WHOIS) if it cannot be found. Affected file is
3240 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Implemented the BAN command to the client library.
3244 * The JOIN command in the server now checks the invite list
3247 * Changed the silc_command_reply_payload_encode_va and the
3248 silc_command_payload_encode_va to support that if argument is
3249 NULL it ignores and checks the next argument. Affected file
3250 lib/silccore/silccommand.c.
3252 * Added silc_server_send_notify_ban to send the BAN notify
3253 type between routers.
3255 * Chaned the silc_notify_payload_encode to support that if
3256 argument is NULL it ignores and checks the next argument.
3257 Affected file lib/silccore/silcnotify.c.
3259 * Tested ban lists in router environment successfully.
3261 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Implemented BAN command to the server, in silcd/command.[ch].
3265 * Removed the BAN and INVITE_LIST modes from the CMODE command
3268 * Added function silc_string_match to regex match two strings.
3269 Affected files lib/silcutil/silcutil.[ch].
3271 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Redefined parts of the SilcChannelEntry in the server to support
3274 the new ban and invite lists.
3276 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3278 * Redefined the INVITE command. The same command can be used to
3279 invite individuals to the channel but also to manage the invite
3280 list of the channel (to add to and remove from the invite list).
3281 Updated the protocol specs.
3283 * Added new command SILC_COMMAND_BAN that can be used to manage
3284 the ban list of the channel. Updated the protocol specs.
3286 * Removed the channel modes: the SILC_CMODE_BAN and the
3287 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3288 in the CMODE command. The equivalent features are now available
3289 using INVITE and BAN commands. Updated the protocol specs.
3291 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3292 in the network about change in the current ban list. The notify
3293 type is not used by the client.
3295 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3296 support the invite lists.
3298 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3300 * Added new function silc_string_regexify that converts string
3301 including wildcard characters into regex string that can
3302 be used by the GNU regex library. Added into the file
3303 lib/silcutil/silcutil.[ch].
3305 Added silc_string_regex_combine to combine to regex strings
3306 into one so that they can be used as one regex string by
3307 the GNU regex library. Added into the file
3308 lib/silcutil/silcutil.[ch].
3310 Added silc_string_regex_match to match two strings. It returns
3311 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3313 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Imported GNU regex to the soruce tree into lib/contrib.
3316 Fixed some compiler warning from the regex.c.
3318 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Fixed MOTD command in the server to work in router environment.
3322 * Fixed the MOTD command in the client library to support
3323 the server argument in the command.
3325 * Added `nickname_len' argument to the silc_idlist_add_client
3326 in the server, as the `nickname' argument may be binary data
3329 * Added silc_idlist_get_channels to return all channels from
3332 * Implemented LIST command to the server. Affected file is
3335 * Implemented the LIST command to the client library and on the
3338 * Added [<user count>] argument to the LIST command reply.
3339 With private channels the user count is not shown.
3341 * Updated TODO and README.
3343 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * The client entry's data.registered must be TRUE even with
3346 global client entry on global client list. The data.registered
3347 is used to check whether the client is anymore in the network,
3348 for example with WHOWAS command so it must be valid.
3350 * Fixed the WHOWAS command in the server. It now actually works
3351 in router environment. Added function into silcd/command_reply.c
3352 silc_server_command_reply_whowas_save.
3354 * Added silc_idlist_purge function to the silcd/idlist.c
3355 to periodically purge the ID Cache.
3357 * Fixed INFO command in the server. It works now in router
3358 environment. Added <server name> argument to the INFO command
3359 reply. Updated the protocol specs.
3361 * Fixed minor bug in silc_idcache_purge to not purge if the
3362 expire value is zero.
3364 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3365 they were buggy because of the WHOWAS information.
3367 * Fixed local command MSG to handle the async resolving of
3368 the remote client properly. It used to fail the first MSG.
3369 Affected file silc/local_command.c.
3371 * Added `data_len' field to SilcIDCache context.
3373 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Update TODO. Todo in commands in the server.
3377 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3380 used by routers as broadcast packet to inform other routers
3381 about the changed user mode.
3383 Implemented the notify handling in the server. Affected file is
3384 silcd/packet_receive.c. Added the function
3385 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3387 * Added new generic Channel Payload and deprecated the New Channel
3388 Payload. The New Channel Payload is now the generic Channel
3391 * Added new argument `mode' to the silc_server_send_new_channel
3392 as it is required in the Channel Payload now.
3394 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3395 and created a new and real SilChannelPayload to represent the
3396 new generic Channel Payload. Implemented the encode/decode
3397 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3399 * Added silc_server_get_client_channel_list to return the list
3400 of channels the client has joined for WHOIS command reply.
3401 Affected file silcd/server.[ch].
3403 * Implemented the channel list sending in the WHOIS command reply
3404 in server and in the client.
3406 Implemented the channel list displaying on the user interface
3407 as well. Affected file silc/client_ops.c.
3409 * Added silc_channel_payload_parse_list to parse list of Channel
3410 Payloads. It returns SilcDList list of SilcChannelPayloads.
3411 Client for example can use this function to parse the list of
3412 channels it receives in the WHOIS command reply. The caller
3413 must free the list by calling silc_channel_payload_list_free.
3414 Affected files lib/silccore/silcchannel.[ch].
3416 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3418 * Added one new argument <user mode> to the WHOIS command reply
3419 to return the mode of the user in SILC. Updated the protocol
3422 Implemented it to the server and client.
3424 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3426 * Fixed the mode printing on the user interface on joining.
3427 Affected file silc/client_ops.c.
3429 * Implemented the UMODE command and user modes in general to the
3430 client library and to the user interface.
3432 * Implemented the UMODE command to the server.
3434 * The server now sends UNKNOWN_COMMAND error status if client sends
3435 unknown command. Affected file silcd/command.c.
3437 * All server commands now handle the command identifier the right
3438 way when sending the command reply to the client. The client can
3439 use to identify the command replies with the identifier.
3441 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added silc_server_get_client_route to resolve the route to
3444 the client indicated by the client ID. Affected file is
3447 * Added silc_server_relay_packet as general function to relay
3448 packet to arbitrary destination. This deprecates functions
3449 like _send_private_message_key, _relay_notify etc. Affected
3450 file is silcd/packet_send.[ch].
3452 Removed silc_server_send_key_agreement,
3453 silc_server_send_private_message_key and
3454 silc_server_packet_relay_notify functions from the file
3455 silcd/packet_send.[ch].
3459 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3460 server. Affected file silcd/packet_receive.[ch].
3462 * Implemented the KILL command to the client. Implemented the
3463 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3464 Affected files lib/silcclient/command[_reply].c and
3465 lib/silcclient/client_notify.c. Implemented the KILL notify
3466 printing in the user inteface.
3468 * Fixed a lot silc_parse_nick memory leaks from the client
3469 library in the file lib/silcclient/command.c.
3471 * Changed the silc_server_send_notify_on_channels's `sender'
3472 argument from SilcSocketConnection to SilcClientEntry to
3473 check the sender as entry and not as connection object and not
3474 to send to the client provided as argument. The affected file
3475 is silcd/packet_send.[ch].
3477 * The notify packets that are destined directly to the client used
3478 to not to be processed by the server. Now changed that and the
3479 server processes all notify packets. After relaying the packet
3480 to the client the notify packet is processed in the server.
3482 * The silc_server_free_client_data now checks whether there is
3483 pending outgoing traffic for the client and purges the data to
3484 the network before removing the client entry.
3486 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3488 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3489 an client is killed from the SILC Network. Updated the protocol
3492 Added new function silc_server_send_notify_killed to the
3493 silcd/packet_send.[ch].
3495 * Added function silc_server_packet_relay_notify to relay notify
3496 packets that are destined directly to a client. In this case
3497 the server does not process the notify packets but merely relays
3498 it to the client. Affected file silcd/packet_send.[ch].
3500 Added also silc_server_packet_process_relay_notify to check
3501 whereto relay the notify. Affected file is
3502 silcd/packet_receive.[ch].
3504 * Implemented the KILL command to the server.
3508 * Added the backup schema desgined last fall to the protocol
3509 specs for everyone to see. The specification is in the
3510 *-spec-xx.txt draft and the packet type definitions for the
3511 backup routers is in *-pp-xx.txt draft. Thusly, added also
3512 new packet type SILC_PACKET_CELL_ROUTERS.
3514 * A big security problem in the implementation discovered. The
3515 signoff of an client did not cause new channel key generation
3516 which it of course should've done. The channel keys must be
3517 always re-generated when client leaves (or signoffs) the channel.
3518 The silc_server_remove_from_channels funtion now handles
3519 the channel key re-generation.
3521 * Added `sender' argument to the silc_server_send_notify_on_channels
3522 to not to send the client provided as argument. Affected file
3523 silcd/packet_send.[ch].
3525 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Implemented OPER and SILCOPER commands into the server and
3530 * Added silc_auth_verify and silc_auth_verify_data to verify
3531 the authentication directly from the authentication payload.
3532 It supports verifying both passphrase and public key based
3533 authentication. Affected file lib/silccore/silcauth.[ch].
3535 * Added `hash' field to the SilcIDListData structure. It is the
3536 hash negotiated in the SKE protocol. Affected file is
3539 * Slight redesigning of the SilcAuthPayload handling routines.
3540 Do not send SilcPKCS but SilcPublicKey as argument.
3542 * Implemented the public key authentication support to the
3543 serverconfig. The public key is loaded from the provided path
3544 and saved as authentication data to void * pointer. Thus,
3545 changed the unsigned char *auth_data to void *auth_data;
3547 * Fixed SHUTDOWN command to send the reply before the server
3548 is shutdown. :) Affected file silcd/command.c.
3550 * Fixed fatal bug in CONNECT command. The hostname was invalid
3551 memory and server crashed. Affected file silcd/command.c.
3553 * Fixed fatal bug in CLOSE command. The server_entry became
3554 invalid but was referenced later in the command. Affected file
3557 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3559 * Fixed fatal bug in failure packet handling. Server ignored
3560 the failure and thus crashed when it came.
3564 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3567 that the command may be executed only once in (about) 2 seconds.
3568 The old SILC_CF_LAG flag is same but allows command bursts up
3569 to five before limiting.
3571 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3572 server code. Various commands now includes the CF_LAG_STRICT
3573 flag to disallow any kind of miss-use of the command.
3575 * Fixed the silc_buffer_unformat to not to allocate any data
3576 if the length of the data is zero. It used to allocate the
3577 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3579 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3581 * Changed the format of AdminConnection configuration section
3582 in the server. Added username of the admin to the format.
3583 Affected files silcd/serverconfig.[ch].
3585 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3586 to return admin configuration data by host, username and/or
3589 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Implemented WHOWAS command to the server. Added the functions:
3593 silc_server_command_whowas_parse,
3594 silc_server_command_whowas_send_reply,
3595 silc_server_command_whowas_from_client and
3596 silc_server_command_whowas_from_server
3598 * Added <Client ID> argument to the WHOWAS command reply. Updated
3599 the protocol specs accordingly.
3601 * Implemented WHOWAS command and command_reply to the client
3604 Implemented the WHOWAS printing on the user interface.
3606 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3608 * Added new argument to the WHOWAS command reply, the real name.
3609 It is an optional argument. Updated the protocol specs.
3611 * Added SilcIDCacheDestructor callback that is registered when
3612 the SilcIDCache is allocated. The callback is called when
3613 an cache entry in the ID Cache expires, or is purged from the
3614 cache. Added into lib/silccore/idcache.[ch].
3616 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3617 to destruct the client entries when the cache entry expires.
3618 Other ID Cache's in server and in the client library ignores
3621 * If the ID Cache entry's `expire' field is zero then the entry
3622 never expires. Added boolean `expire' argument to the
3623 silc_idcache_add function in the lib/silccore/idcache.[ch].
3624 If it is TRUE the default expiry value is used.
3626 * Added silc_server_free_client_data_timeout that is registered
3627 when client disconnects. By default for 5 minutes we preserve
3628 the client entry for history - for WHOWAS command.
3630 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Added support to the server to enforce that commands are not
3633 executed more than once in 2 seconds. If server receives
3634 commands from client more frequently, timeout is registered
3635 to process the commands. Affected file silcd/command.c.
3636 Added new function silc_server_command_process_timeout.
3638 * Changed NICK_NOTIFY handling in client library to check that
3639 if the client's nickname was changed, so there is no need to
3640 resolve anything from the server.
3642 * Removed error printing from the WHOIS and IDENTIFY commands.
3643 If error occurs then it is ignored silently in the client library.
3644 The application, however, may map the received error to
3645 human readable error string. The application currently maps
3646 the NO_SUCH_NICKNAME error to string.
3648 * Made the command status message public to the application. Moved
3649 them from lib/silcclient/command_reply.c to
3650 lib/silcclient/command_reply.h. The application can map the
3651 received command status to the string with the
3652 silc_client_command_status_message function.
3654 * Added check to the server to check that client's ID is same
3655 as the Source ID in the packet the client sent. They must
3658 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3660 * Added dist-bzip hook to the Makefile.am to make bzip2
3661 compressed distributions.
3663 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Server now enforces the maximum length for the nickname and
3666 the channel as protocol specification dictates. 128 bytes for
3667 nickname and 256 bytes for channel name.
3669 * Moved the WHOIS printing to the application. The client libary
3670 does not print out the WHOIS information anymore, the application
3671 must do it. Renamed silc_client_command_reply_whois_print to
3672 the silc_client_command_reply_whois_save.
3674 The client's idle time is also sent to the application now, and
3675 the idle is shown on screen.
3677 * Added silc_client_command_reply_identify_save to save the
3678 received IDENTIFY entries.
3680 * Do not check for channel private keys in message sending and
3681 reception if the channel does not have the PRIVKEY mode set.
3682 Affected file lib/silclient/client_channel.c.
3684 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3686 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3687 just surfaced after chaning the JOIN procedure.
3689 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Added silc_client_get_clients_by_list to get client entries
3692 from Client ID list, that is returned for example by JOIN
3693 and USERS command replies. The application should use this
3694 function for example when JOIN command reply is received to
3695 resolve the clients already on the channel (library does not
3696 do that anymore as USERS command reply is not used in the JOIN
3697 procedure anymore). Affected files lib/silcclient/silcapi.h and
3698 lib/silcclient/idlist.c.
3700 * JOIN command reply and USERS command reply returns now SilcBuffer
3701 pointers instead of unsigned char pointers when returning
3702 the client list and mode list.
3704 * Added <Client ID> argument to the JOIN command reply, mainly
3705 for the server to identify for which client the command was
3706 originally sent. Updated protocol specs accordingly.
3708 * Added SilcDlist private_key pointer to the SilcChannelEntry
3709 in the client to support the channel private keys. Affected
3710 file is lib/silcclient/idlist.h.
3712 * Added SilcChannelPrivateKey argument to the function
3713 silc_client_send_channel_message so that application can choose
3714 to use specific private ke if it wants to. If it is not provided,
3715 the normal channel key is used, unless private keys are set.
3716 In this case the first (key that was added first) is used
3717 as the encryption key.
3719 * Implemented the support for channel private key handling.
3720 Implemented the following functions:
3722 silc_client_add_channel_private_key,
3723 silc_client_del_channel_private_keys,
3724 silc_client_del_channel_private_key,
3725 silc_client_list_channel_private_keys and
3726 silc_client_free_channel_private_keys
3728 Affected file lib/silcclient/client_channel.c.
3730 * Added the support for the private keys in the channel message
3731 sending and encryption and in the message reception and
3732 decryption. Affected funtions are
3733 silc_client_send_channel_message and silc_client_channel_message.
3735 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3737 * Added SKE's key verify callback to the client library's
3738 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3740 * Removed the statement that server (or router) must send USERS
3741 command reply when joining to the channel so that the client
3742 knows who are on the channel. Instead, the client list and
3743 client's mode list is now sent in the JOIN command reply to the
3744 client who joined channel. This is better solution.
3746 * Added function silc_server_get_users_on_channel and function
3747 silc_server_save_users_on_channel to the silcd/server.[ch].
3749 * Removed function silc_server_command_send_users from the
3752 * Do not show topic on the client library anymore. The topic is
3753 sent in the command reply notify to the application and the
3754 application must show the topic now.
3756 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Added client searching by nickname hash into the IDENTIFY and
3759 WHOIS commands in the server as they were clearly missing from
3760 them. Affected file is silcd/command.c.
3762 * Fixed a bug in private message receiving in the client library.
3763 The remote ID was freed and it wasn't supposed, now it is
3766 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3768 * Minor fix to the channel payload; allocate the data area, as it
3769 needs to be of specific length.
3771 * If the key agreement port is zero then the operating
3772 system will define the bound port. Affected files are
3773 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3775 * Added new function silc_channel_payload_decrypt into the file
3776 lib/silccore/silcchannel.[ch].
3778 * Moved the channel message etc, check from silc_packet_decrypt
3779 to applications. The library calls now a generic
3780 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3781 when the packet is either normal or special. This was done to
3782 allow more wide range of checking that was not allowed when
3783 the code was in library. Now applications can do virtually any
3784 checks to the packet and return to the library the decision how
3785 the packet should be processed. Affected files are
3786 lib/silccore/silcpacket.[ch].
3788 Added silc_server_packet_decrypt_check to the server and
3789 silc_client_packet_decrypt_check to the client library.
3791 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3792 to send with specified source and destination information.
3794 * Channel message delivery between routers was broken after the
3795 channel key distribution was fixed earlier. The channel key
3796 was used be to distributed to other routers as well which is not
3797 allowed by the protocol. Now this is fixed and channel keys
3798 really are cell specific and the channel message delivery between
3799 routers comply with the protocol specification.
3801 * Fixed various commands in server to check also the global list
3802 for the channel entry and not just the local list. The affected
3803 file silcd/command.c.
3805 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Added assert()s to buffer formatting and unformatting routines
3808 to assert (if --enable-debug) when error occurs. Affected
3809 file: lib/silcutil/silcbuffmt.c.
3811 * Changed to auto-reconnect to check whether the remote host is
3812 router and register the re-connect timeout if it is. It used
3813 to check that whether we are normal server, but router must do
3814 auto-reconnect with another router as well. Affected file
3817 * Removed the [<key len>] option from CMODE command as the cipher
3818 name decides the key length, nowadays. See the defined ciphers
3819 from the protocol specification.
3821 * Added [<hmac>] option to the CMODE command to define the HMAC
3822 for the channel. Added SILC_CMODE_HMAC channel mode.
3824 * Added [<hmac>] option for the JOIN command so that user can
3825 select which HMAC is used to compute the MACs of the channel
3828 * Added Hmac field to the Channel Message Payload. The integrity
3829 of plaintext channel messages are now protected by computing
3830 MAC of the message and attaching the MAC to the payload. The
3831 MAC is encrypted. Now, it is clear that this causes some
3832 overhead to the size of the packet but rationale for this is that
3833 now the receiver can verify whether the channel message decrypted
3834 correctly and also when private keys are set for the channel the
3835 receiver can decrypt the packet with several keys and check from
3836 the MAC which key decrypted the message correctly.
3838 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3839 lib/silccrypt/silccipher.[ch].
3841 * Added silc_hash_len to return the digest length into the
3842 lib/silcrypt/silchash.[ch].
3844 * Rewrote parts of Silc Channel Payload interface in the
3845 lib/silccore/silcchannel.[ch]. The encode function now also
3846 encrypts the packet and parse function decrypts it.
3848 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Fixed a minor formatting bug in the SKE's key material processing.
3851 It actually might have processed the keys wrong way resulting
3854 * Redefined the mandatory HMAC algorithms and added new algorithms.
3855 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3856 and hmac-md5 truncated to 96 bits. The mandatory is now
3857 hmac-sha1-96. Rest are optional (including the one that used
3858 to be mandatory). Rationale for this is that the truncated HMAC
3859 length is sufficient from security point of view and can actually
3860 make the attack against the HMAC harder. Also, the truncated
3861 HMAC causes less overhead to the packets. See the RFC2104 for
3864 * Added new [hmac] configuration section. The SKE used to use
3865 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3866 is of course wrong. The official names that must be proposed in
3867 the SKE are the ones defined in the protocol specification
3868 (hmac-sha1-96 for example). The user can configure any hmac
3869 using any hash function configured in the [hash] section. At
3870 least, the mandatory must be configured.
3872 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3874 * Added HMAC list to the SKE proposal list. It has now both
3875 hash algorithm list and HMAC list. This makes the protocol
3876 incompatible with previous versions. The SKE now seems to work
3877 the way it is supposed to work, for the first time actually.
3879 * Defined plain Hash algorithms to the protocol specification.
3882 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Implemented support for key agreement packets into the server.
3885 Added functions silc_server_key_agreement and
3886 silc_server_send_key_agreement. Other than these functions,
3887 server has nothing to do with this packet.
3889 * Added support for private message key packets into the server.
3890 Added functions silc_server_private_message_key and
3891 silc_server_send_private_message_key.
3895 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3896 called in the protocol's final callback instead in the END
3897 protocol state. This makes a little more sense and in the same
3898 time in client we can use the same protocol routines for normal
3899 key exchange and to key agreement packet handling as well.
3901 * Added to both client's and server's KE protocol context the
3902 SilcSKEKeyMaterial pointer to save the key material. We will
3903 bring the key material to the protocol's final callback by doing
3904 this. The final callback must free the key material.
3906 * Added SKE's packet_send callback into client's KE protocol
3907 context so that the caller can choose what packet sending function
3908 is used. This way we can use different packet sending when
3909 doing normal SKE when doing key agreement packet handling (in
3910 the key agreement packet handling we do not want to encrypt
3913 * Implemented the responder side of the key agreement routines
3914 in the client. The client can now bind to specified port and
3915 accept incoming key negotiation. The key material is passed
3916 to the application after the protocol is over.
3918 * Implemented the processing of incoming Key Agreement packet
3919 in the client. Added function silc_client_key_agreement to
3922 * Implemented the intiator side of the key agreement routines
3923 in the client. The client can now initiate key agreement with
3924 another remote client. The key material is passed to the
3925 application after the protocol is over.
3927 * Created client_keyagr.c to include all the key agreement
3930 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3931 SILC_TASK_CALLBACK except that it is not static.
3933 * Created client_notify.c and moved the Notify packet handling
3934 from the client.[ch] into that file.
3936 * Created client_prvmsg.c and moved all private message and
3937 private message key routines from the client.[ch] into that file.
3939 * Create client_channel.c and moved all channel message and
3940 channel private key routines from the client.[ch] into that file.
3942 * Changed silc_client_get_client_by_id_resolve to resolve with
3943 WHOIS command instead of IDENTIFY command, in the file
3944 lib/silclient/idlist.c.
3946 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Implemented the SKE's responder side to the Client library.
3950 * When FAILURE is received to the protocol do not trust it
3951 blindly. Register a timeout to wait whether the remote closes
3952 the connection as it should do it, only after that process the
3953 actual failure. This was changed to both client and server.
3955 * Added client_internal.h to include some of the structures
3956 there instead of client.h in lib/silcclient/.
3958 * Added function silc_task_unregister_by_callback to unregister
3959 timeouts by the callback function.
3961 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * Some "Incomplete WHOIS info" errors has been appearing on the
3964 log files. Took away the entry->userinfo check from WHOIS
3965 reply sending. The entry->userinfo is now " " if client did not
3966 provide one. I thought this was fixed earlier but something
3967 is wrong still. Let's see if the error still appears.
3969 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3971 * Fixed a minor bug in the login when the channel key is
3972 re-generated in the server. It used to generate the key in
3973 wrong order and thus caused problems in the channel traffic.
3975 * Fixed a minor bug in channel key distsribution after
3976 KICK command. The key was not sent to the router even though
3979 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3981 * Added silc_ske_process_key_material_data as generic routine
3982 to process any key material as the SILC protocol dictates. The
3983 function is used by the actual SKE library but can be used by
3984 applications as well. This relates to the private message keys
3985 and the channel private keys since they must be processed the
3986 same way the normal SILC session keys. The protocol dictates
3987 this. Affected files: lib/silcske/silcske.[ch].
3989 Added also silc_ske_free_key_material to free the
3990 SilcSKEKeyMaterial structure.
3992 * Defined silc_cipher_set_key function to set the key for
3993 cipher without using the object's method function. The affected
3994 files: lib/silccrypt/silccipher.[ch].
3996 * Implemented silc silc_client_add_private_message_key,
3997 silc_client_add_private_message_key_ske,
3998 silc_client_del_private_message_key,
3999 silc_client_list_private_message_keys and
4000 silc_client_free_private_message_keys functions in the
4003 Added functions silc_client_send_private_message_key to send
4004 the Private Message Key payload and silc_client_private_message_key
4005 to handle incoming Private Message Key payload.
4007 * Added Cipher field to the Private Message Key payload to set
4008 the cipher to be used. If ignored, the default cipher defined
4009 in the SILC protocol (aes-256-cbc) is used.
4011 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Removed lib/silcclient/ops.h file.
4015 Redefined parts of the SILC Client Library API. Created new
4016 file silcapi.h that deprecates the ops.h file and defines the
4017 published Client Library API. Defined also private message key
4018 API and channel private key API into the file.
4020 This is the file that the application must include from the
4021 SILC Client Library. Other files need not be included by
4022 the application anymore.
4024 * Added new key_agreement client operation callback and also
4025 defined the Key Agreement library API for the application.
4027 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4030 is used by clients to request key negotiation between another
4031 client in the SILC network. If the negotiation is started it
4032 is performed using the SKE protocol. The result of the
4033 negotiation, the secret key material, can be used for example
4034 as private message key.
4036 Implemented the Key Agreement payload into the files
4037 lib/silccore/silauth.[ch].
4039 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Redefined ciphers for the SILC protocol. Added some new ciphers
4042 and defined the key lengths for the algorithms. Changed the
4043 code accordingly. The default key length is now 256 bits.
4045 * Fixed SKE key distribution function silc_ske_process_key_material
4046 when the key length is more than 128 bits. The default key
4047 length in SILC is now 256 bits.
4049 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4050 to indicate unsupported algorithm.
4052 * Renamed rijndael.c to aes.c and all functions as well.
4054 * Fixed a long standing channel key setting bug in client library.
4055 Weird that it has never surfaced before.
4057 * Fixed bug in channel deletion. If the entire channel is removed
4058 then it must also delete the references of the channel entry
4059 from the client's channel list as the client's channel entry and
4060 the channel's client entry share same memory.
4062 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Implemented CONNECT and SHUTDOWN commands in the client.
4066 * Implemented CLOSE command to the client.
4068 * Added the function silc_idlist_find_server_by_name into the
4069 files silcd/idlist.[ch].
4071 Added the function silc_idlist_find_server_by_conn into the
4072 files silcd/idlist.[ch].
4074 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * DIE command was renamed to SHUTDOWN. Updated the both code
4079 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4080 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4082 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4085 * Added function silc_server_create_connection function to create
4086 connection to remote router. My server implementation actually
4087 does not allow router to connect to normal server (it expects
4088 that normal server always initiates the connection to the router)
4089 so the CONNECT command is only good for connecting to another
4092 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4095 or some other client was kicked from the channel.
4097 Implemented the handling of the notify type to both client
4100 Implemented silc_server_send_notify_kicked to send the KICKED
4101 notify. It is used to send it to the server's primary router.
4103 * Implemented the KICK command into server and client.
4105 * Added `query' argument to the silc_idlist_get_client function
4106 to indicate whether to query the client from server or not if
4109 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4110 to indicate that the client is not channel founder.
4114 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Removed the rng context from SilcPacketContext structure and
4117 changed that the packet routine uses the Global RNG API.
4119 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Added support for quit message that client can "leave" on the
4122 channel when it quits the SILC. It is ditributed inside the
4123 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4125 Added silc_server_free_client_data that will take the
4126 signoff message as argument.
4128 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4130 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Updated parts of the protocol specification to keep it up
4135 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4137 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4138 payloads in one packet.
4140 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4141 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4142 use now the new List flag.
4144 * Also deprecated the following packet types: REPLACE_ID,
4145 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4147 * Added list support for Notify packet in server.
4149 * Added silc_server_send_notify_channel_change to send the
4150 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4151 the silc_server_send_replace_id.
4153 * Added silc_server_send_notify_nick_change to send the
4154 NICK_CHANGE notify type. Deprecates the function
4155 silc_server_send_replace_id.
4157 * Added silc_server_send_notify_join to send the JOIN notify type.
4158 Deprecates the function silc_server_send_new_channel_user.
4160 * Added silc_server_send_notify_leave to send LEAVE notify type.
4161 Deprecates the function silc_server_send_remove_channel_user.
4163 * Added silc_server_send_notify_cmode and
4164 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4165 types. Deprecates the silc_server_send_set_mode function.
4167 * Added SERVER_SIGNOFF notify type to indicate that server has
4168 quit. This means that all clients on the channel from that
4169 server will drop. This can be also used when netsplit happens.
4171 Deprecated REMOVE_ID packet type since it is not needed anymore
4174 Added silc_server_send_notify_server_signoff to send the
4175 SERVER_SIGNOFF notify type. Deprecates the function
4176 silc_server_send_remove_id.
4178 Added also silc_server_send_notify_signoff to send the
4179 SIGNOFF notify type.
4181 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4182 SILC protocol from this day on. Changed the protocol
4183 specification as well.
4185 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4186 notify type. It is used between routers to notify about
4187 topic changes on a channel.
4189 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4192 * Partly updated the protocol specification to comply with the
4193 changes now made. It is still though a bit outdated.
4195 * The JOIN notify type now takes one extra argument <Channel ID>.
4196 The packet used to be destined to the channel but now the
4197 JOIN type may be sent as list thus it is impossible to
4198 destine it to any specific channel. By adding this argument
4199 it is again possible.
4201 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Added CREDITS file. The CHANGES and CREDITS file will appear
4204 in the distribution as well.
4206 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4208 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4209 types in the server's silcd/packet_receive.c.
4211 * Implemented CMODE and CUMODE to work in router environment.
4213 * Fixed minor encoding and decoding buglet from the
4214 lib/silccore/silcmode.c.
4216 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4219 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4221 * Changed all SilcConfigServer* and silc_config_server* to
4222 SilcServerConfig* and silc_server_config*, respectively.
4225 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4227 * Associated the ID (client or server ID) to the Authentication
4228 Payload to avoid any possibility of forging. Updated the
4229 protocol specification and the code accordingly.
4231 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * The RSA key length is now save to the RsaKey context in the
4234 key generation process in lib/silccrypt/rsa.c. The key length
4235 is now used to figure out the maximum size of the block allowed
4236 to be encrypted/signed.
4238 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4239 is equivalent to the silc_mp_mp2bin but does not allocate any
4242 * Changed silc_mp_mp2bin API to take length argument. If it is
4243 non-zero then the buffer is allocated that large. If zero, then
4244 the size is approximated using silc_mp_sizeinbase, which however
4247 * Created Global RNG API which is global RNG that application can
4248 initialize. After initializing, any routine anywhere in the
4249 code (including library) can use RNG without allocating a new
4250 RNG object. This was done to allow this sort of use of the
4251 RNG in code that has no chance to allocate RNG object. All
4252 applications currently allocate this and many routines in the
4253 library use this. Affected file lib/silccrypt/silcrng.[ch].
4255 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4256 it to use the Global RNG API.
4258 * Defined Authentication Payload into protocol specification that
4259 is used during SILC session to authenticate entities. It is
4260 used for example by client to authenticate itself to the server
4261 to obtain server operator privileges.
4263 Implemented this payload into the lib/silccore/silcauth.[ch].
4264 Implemented also routines for public key based authentication
4265 as the new protocol specification dictates.
4267 Moved definitions of different authentication methods from
4268 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4270 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4271 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4272 silc_pkcs_verify_with_hash functions into the file
4273 lib/silccrypt/silcpkcs.[ch].
4275 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * The client entry's userinfo pointer must be always valid.
4278 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4279 will fail since it requires the userinfo. Now, the userinfo
4280 is allocated as "" if actual userinfo does not exist. Actually,
4281 it must exist and it is totally Ok to drop client connections
4282 that does not announce the userinfo. However, we will make
4283 this workaround for now.
4285 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4286 to return the remote port by socket.
4288 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4291 SILC_SERVER_PENDING_EXEC and added an new macro
4292 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4293 data or when error occurs while processing the pending command.
4295 Added new argument `destructor' into silc_server_command_pending
4296 and to the SilcServerCommandPending object. This destructor is
4297 now called after calling the pending callback or if error occurs
4298 immediately. If error occurs the actual pending callback won't
4299 be called at all - only the destructor. The destructor may be
4300 NULL if destructor is not needed.
4302 All this applies for client library code as well. Similar
4303 changes were made there as well for the pending commands.
4305 In the client, the application must now allocate the
4306 SilcClientCommandContext with the silc_client_command_alloc
4309 * Added reference counter to the SilcServerCommandContext. Added
4310 function silc_server_command_alloc and silc_server_command_dup
4313 Same type of functions added to the client library for the same
4316 * Removed the cmd_ident from IDListData away since it is now
4317 global for all connections. It is the command identifier used
4318 in command sending and with pending commands. The affected file
4321 * Added reference counter to the SilcSocketConnection objecet to
4322 indicate the usage count of the object. The object won't be
4323 freed untill the reference counter hits zero. Currently only
4324 server uses this, and client ignores it. The client must be
4325 set to use this too later. The affected files are
4326 lib/silccore/silcsockconn.[ch]. Added also the function
4327 silc_socket_dup to increase the reference counter.
4329 This was mainly added because it is possible that the socket
4330 is removed underneath of pending command or other async
4331 operation. Now it won't be free'd and proper DISCONNECTING
4332 flags, etc. can be set to avoid sending data to connection that
4333 is not valid anymore.
4335 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4336 the connection. After that it sets SILC_SET_DISCONNECTED.
4337 It is, however, possible that the socket data is not still freed.
4338 The silc_server_packet_process now checks that data is not
4339 read or written to connection that is DISCONNECTED. The socket
4340 get's freed when the reference counter hits zero.
4342 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Changed the client operation API: channel_message operation's
4345 `sender' is now the client entry of the sender, not the nickname
4346 and the `channel' is the channel entry, not the channel name.
4348 In the private_message operation the `sender' is now also the
4349 client entry of the sender not the nickname.
4351 Affected file is lib/silcclient/ops.h and all applications
4352 using the client operations.
4354 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Moved the calling of ops->connect() from connect_to_server_final
4357 into receive_new_id functin since that is the point when the
4358 client is actually allowed to send traffic to network. The
4359 affected file is lib/silcclient/client.c.
4361 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4364 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4365 (if needs broadcasting) instead of broadcasting the packets one
4366 by one which would make a burst in the network traffic.
4368 * Added `broadcast' argument to the functions in silcd/server.[ch]
4369 silc_server_create_new_channel[_with_id] to indicate whether
4370 to send New Channel packet to primary router.
4372 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Added new function into the silcd/server.[ch] files:
4375 silc_server_create_new_channel_with_id to create new channel with
4376 already existing Channel ID.
4378 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4379 lib/silccore/silcpacket.h. This packet is used t send list of
4380 Set Mode payloads inside one packet. Server uses this to set
4381 the modes for the channels and clients on those channels, that it
4382 announced to the router when it connected to it. The protocol
4383 specification has been updated accordingly.
4385 * The silc_server_new_channel did not handle the packet coming
4386 from normal server as it normally does not send that. However,
4387 when it announces its channels it does send it. Implemented
4388 the support for that.
4390 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4391 into the file lib/silccore/id.h.
4393 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed memory leaks in the functions silc_idlist_del_client,
4396 silc_idlist_del_channel and silc_idlist_del_server in the file
4397 silcd/idlist.c. All of those leaked like a sieve.
4399 * Fixed some small memory leaks in the client's function
4400 silc_client_notify_by_server.
4402 * Added functions into silcd/server.c: silc_server_announce_clients,
4403 silc_server_announce_channels and silc_server_announce_server.
4404 These functions are used by normal and router server to announce
4405 to its primary router about clients, channels and servers (when
4406 router) that we own. This is done after we've connected to the
4409 These functions effectively implements the following packet types:
4410 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4411 and SILC_PACKET_NEW_ID_LIST.
4413 * Added new functions into the silcd/packet_receive.[ch]:
4414 silc_server_new_id_list, silc_server_new_channel_list and
4415 silc_server_new_channel_user_list to handle the incoming
4416 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4418 * Added support of changing Channel ID in the function
4419 silc_server_replace_id. If the server that announces a channel
4420 to the router already exists in the router (with same name but
4421 with different Channel ID), router is responsible to send
4422 Replace ID packet to the server and force the server to change
4423 the Channel ID to the one router has.
4425 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4426 client that the Channel ID has been changed by the router. The
4427 normal server sends this to the client. Client must start using
4428 the new Channel ID as the channel's ID.
4430 Implemented handling of this new type into lib/silcclient/client.c
4431 into the function silc_client_notify_by_server.
4433 * Added new function silc_idlist_replace_channel_id into the files
4434 silcd/idlist.[ch] to replace the Channel ID.
4436 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Call silc_server_command_identify_check always when processing
4439 the IDENTIFY command in silcd/command.c
4441 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4443 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4444 send keepalive packets. The packet can be sent by clients,
4445 servers and routers.
4447 Added function silc_socket_set_heartbeat into the file
4448 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4449 If not set, the heartbeat is not performed. The actual
4450 heartbeat is implemented in the low level socket connection
4451 library. However, application is responsible of actually
4454 Added silc_server_send_heartbeat to send the actual heartbeat
4455 packet into silcd/packet_send.[ch]. Server now performs
4456 keepalive with all connections.
4458 * Added silc_task_get_first function into lib/silcutil/silctask.c
4459 to return the timeout task with shortest timeout. There was a bug
4460 in task unregistration that caused problems. TODO has been
4461 updated to include that task system must be rewritten.
4463 * The client library will now resolve the client information when
4464 receiving JOIN notify from server for client that we know but
4465 have incomplete information.
4467 * Rewrote parts of silc_server_remove_from_channels and
4468 silc_server_remove_from_one_channel as they did not remove the
4469 channel in some circumstances even though they should've.
4471 * Encryption problem encountered in server:
4473 The LEAVE command used to send the Channel Key packet to the
4474 router immediately after generating it. However, the code
4475 had earlier sent Remove Channel user packet but not immediately,
4476 ie. it was put to queue. The order of packets in the router
4477 was that Channel Key packet was first and Remove Channel User
4478 packet was second, even though they were encrypted in the
4479 reverse order. For this reason, MAC check failed. Now, this
4480 is fixed by not sending the Channel Key packet immediately but
4481 putting it to queue. However, this is more fundamental problem:
4482 packets that are in queue should actually not be encrypted
4483 because packets that are sent immediately gets encrypted
4484 actually with wrong IV (and thus MAC check fails). So, packets
4485 that are in queue should be encrypted when they are sent to
4486 the wire and not when they put to the queue.
4488 However, the problem is that the current system has not been
4489 designed to work that way. Instead, the packet is encrypted
4490 as soon as possible and left to the queue. The queue is then
4491 just purged into wire. There won't be any fixes for this
4492 any time soon. So, the current semantic for packet sending
4495 o If you send packet to remote host and do not force the send
4496 (the packet will be in queue) then all subsequent packets to the
4497 same remote host must also be put to the queue. Only after the
4498 queue has been purged is it safe again to force the packet
4501 o If you send all packets immediately then it safe to send
4502 any of subsequent packets through the queue, however, after
4503 the first packet is put to queue then any subsequent packets
4504 must also be put to the queue.
4506 Follow these rules and everything works fine.
4508 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Added new function silc_server_remove_clients_by_server to
4511 remove all client entries from ID list when the server connection
4512 is lost. In this case it is also important to invalidate all
4513 client entires as they hold the invalid server entry. This
4514 fixes fatal bug when server has lost connection and will reconnect
4517 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Made some sanity checks to silc_server_daemonise like to check
4520 whether the requested user and group actually exists.
4522 * Added sanity check to SKE's silc_ske_responder_finish to check
4523 that the public and private key actually is valid.
4525 * Invalidate the client's nickname when receiving Replace ID
4526 packet and the Client ID is being replaced. This means that the
4527 server will query the nickname if someone needs it (client)
4530 * Sort the ID Cache in client library when the ID Cache data
4531 has changed (needs sorting).
4533 * Do not allow for SILC client to create several connections to
4534 several servers. The client does not support windows right now
4535 and generating multiple connections causes weird behaviour.
4537 Irssi-silc client does support windows and can handle several
4538 connections without problems, see: www.irssi.org and SILC plugin.
4540 * Fixed some places where client was added to the IDList. The
4541 rule of thumb is following (in order to get everything right):
4542 If the client is directly connected local client then the
4543 `connection' argument must be set and `router' argument must be
4544 NULL to silc_idlist_add_client function. If the client is not
4545 directly connected client then the `router' argument must
4546 bet set and the `connection' argument must be NULL to the
4547 silc_idlist_add_client function.
4549 * The funtion silc_server_packet_send_local_channel actually did
4550 not check whether the client was locally connected or not. It
4551 does that now. Fixed a bug related to LEAVE command.
4553 * Fixed Remove Channel User payload parsing bug in server's
4554 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4556 * The server's silc_server_save_channel_key now checks also the
4557 global ID list for the channel as it might not be in the local
4558 list. Fixed a bug related to LEAVE command.
4560 * Is this the end of the [<unknown>] buglet that has been lurking
4561 around for a long time? A little for loop fix in server's
4562 silc_server_command_whois_parse that is used by both IDENTIFY
4563 and WHOIS command. At least, this was a clear bug and a cause
4564 of one type of [<unknown>] buglet.
4566 * WHOIS and IDENTIFY commands call the function
4567 silc_server_command_[whois/identify]_check function even if
4568 we are not router server.
4570 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Added --with-gmp configuration option. If set the GMP
4573 is always compiled in the SILC source tree. If not set then
4574 it is checked whether the system has the GMP3 installed. If
4575 it has then the GMP won't be compiled (the system's headers
4576 and library is used), if it doesn't have it then the GMP is
4577 compiled in the SILC source tree.
4579 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Changed RSA private exponent generation to what PKCS #1
4582 suggests. We try to find the smallest possible d by doing
4583 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4584 not security fix but optimization.
4586 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Added new config entry [Identity] to fork the server and run
4589 it as specific user and group. A patch from Bostik.
4591 * Imported Dotconf configuration library into lib/dotconf.
4592 This will be used to create the SILC configuration files later.
4593 It will appear in the distsribution after this commit.
4595 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * A big code auditing weekend happening. Auditing code for
4598 obvious mistakes, bugs and errors. Also, removing any code
4601 Removed files for being obsolete:
4603 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4604 inline in the file lib/silcutil/silcbuffer.h)
4606 o lib/silcutil/silcbufutil.c (the header has inline versions)
4608 Changed code to fix possible error conditions:
4610 o The buffer formatting routines now check that the destination
4611 buffer really has enough space to add the data. This applies for
4612 both buffer formatting and unformatting
4613 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4614 unformatting was changed to accomodate following rules:
4615 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4616 sent to the function while XXX_*STRING will not allocate or copy
4617 the data into the buffer. Instead it sets the pointer from the
4618 buffer into the pointer sent as argument (XXX_*STRING used to
4619 require that the pointer must be allocated already). This change
4620 makes this whole thing a bit more consistent and more optimized
4621 (note that the data returned in the unformatting with XXX_*STRING
4622 must not be freed now). The routines return now -1 on error.
4624 o Tried to find all code that use buffer_format and buffer_unformat
4625 and added return value checking to prevent formatting and
4626 especially unformatting errors and possible subsequent fatal
4629 o Changed ske->x and ske->KEY to mallocated pointers in
4630 lib/silcske/silcske.h. Fixed possible data and memory leak.
4632 o Added return value checking to all *_parse* functions. Fixed
4633 many memory leaks as well.
4635 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4636 so that buffer overflows would not happen. All code now also
4637 checks the return value as it can fail.
4639 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4641 * Added reconnection support to server if the normal server looses
4642 its connection to the router (for example if router is rebooted).
4643 The server performs normal reconnection strategy implemented
4644 to the server. Affected file silcd/server.c.
4646 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Added new packet type SILC_PACKET_SET_MODE that is used to
4649 distribute the information about changed modes (for clients,
4650 channels and clients channel modes) to all routers in the
4651 network. Updated the protocol specification accordingly.
4653 Added functions into silcd/packet_send.c and
4654 silcd/packet_receive.c: silc_server_send_set_mode,
4655 silc_server_set_mode.
4657 Added new files silcmode.[ch] into lib/silccore that implements
4658 the encoding and decoding of Set Mode Payload. Added new type
4659 SilcSetModePayload. Moved the definitions of different modes
4660 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4662 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4664 * Oops, a little mistake in server's connection authentication
4665 protocol. The protocol is not ended with FAILURE but with
4666 SUCCESS if the authentication is Ok. :) Affected file is
4669 * Implemented NICK_CHANGE notify handling in server in the file
4670 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4671 the local clients on the channel. After the changing nickname
4672 in router environment snhould work and the [<unknown>] nickname
4673 should appear no more.
4675 The silc_server_replace_id function that receives the Replace ID
4676 payload now sends the NICK_CHANGE notify type also in the file
4677 silcd/packet_receive.c
4679 * Changed WHOIS and IDENTIFY command to support the maximum amount
4680 of arguments defined in protocol specs (3328 arguments). This
4681 fixed a bug that caused problems when there were more than three
4684 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Added extra parameter, command identifier, to the
4687 silc_client_send_command so that explicit command identifier
4690 Changed that ID list routines uses specific command identifier
4691 when sending WHOIS/IDENTIFY requests to the server so that they
4692 can be identified when the reply comes back.
4694 Affected files lib/silcclient/command.[ch],
4695 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4697 * Added `sender' argument to silc_server_packet_send_to_channel
4698 to indicaet the sender who originally sent the packet to us
4699 that we are now re-sending. Ignored if NULL. Affected file
4700 silcd/packet_send.[ch].
4702 * Added some server statistics support in silcd/server_internal.h
4703 SilcServerStatistics structure and around the server code. Also
4704 send some nice statistics information when client is connecting
4707 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Fixed channel ID decoding in server's JOIN command reply in
4710 silcd/command_reply.c
4712 * Fixed braodcasting of replace ID payload to not to send it if
4713 we are standalone server in silcd/packet_receive.c.
4715 * Fixed all channel message sending routines to not to send
4716 packets to clients that has router set, since they are routed
4717 separately in the same function earlier. Affects file
4718 silcd/packet_send.c and all channel packet sending functions.
4720 * In USERS reply, res_argv[i] are not allocated, the table
4721 is allocated. Thus changed that free the table, not its
4724 * In server's whois_check and identify_check if the client is
4725 locally connected do not send any WHOIS commands - they are not
4728 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Fixed some minor bugs in client when sending WHOIS command. The
4731 arguments was in wrong order.
4733 * Removed statis function add_to_channel from server in
4734 silcd/command.c that was previously used with the joining but
4737 * Tested USERS command in router environment successfully with two
4738 routers, two servers and two clients.
4740 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Reorganized the USERS command and command reply in client library
4743 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4744 When the command is given by user we register a pending command
4745 callback that will reprocess the command after the reply has been
4746 received from the server. When reprocessing the packet we then
4747 display the information. Thus, the USERS information is displayed
4748 now in the command callback instead of in the command reply
4749 callback. The processing of the command is same as previously
4750 when server has sent the command reply in the JOINing process.
4752 * Added to USERS command in silcd/command_reply.c to join the client,
4753 we didn't use to know about, to the channel after we've created
4754 a client entry for it. Also, for clienet we did know already still
4755 check whether it is on the channel or not and add it if not.
4757 * Removed silc_server_command_join_notify as the function and its
4760 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4762 * Changed the client's pending command handling to the same as the
4763 server's pending command handling. It is also now possible to
4764 execute command reply functions from other command reply
4765 function as the function callbacks for commands and command
4766 replies are one and same. The pending commands are not static
4767 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4768 in client connection context. Thus, pending commands are server
4769 connection specific as it is convenient.
4771 Changed the function silc_client_command_pending and
4772 silc_client_command_pending_del and added new function
4773 silc_client_command_pending_check. Removed the
4774 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4777 * Added cmd_ident, current command identifier, to the client
4778 connection context in lib/silcclient/client.h to keep track on
4779 command identifiers used in command sending. Client's command reply
4780 function handling now supports the mandatory command identifiers.
4782 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4783 funtions in client to fully support pending command callbacks.
4785 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4786 as one of the arguments to the application in the command reply
4789 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4790 before first releasing SILC but came back. Now it is removed again
4791 and should come back nomore. The FORWARDED flag was used only
4792 by the JOINing procedure by forwarding the command packet to router.
4793 Now, the JOINing procedure has been changed to more generic (due
4794 to various router environment issues) and FORWARDED is not needed
4795 anymore for anything. The protocol specification is yet to be
4798 Now, removed silc_server_packet_forward from server and the flag
4799 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4801 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Renamed NAMES command to USERS command. The NAMES was named that
4804 due to historical reasons. Now it is renamed. Also, rewrote
4805 parts of the USERS command. The nickname list is not sent anymore
4806 by the server. Only Client ID and mode lists are sent in the USERS
4807 command. Changed this also to the protocol specification.
4809 The client now resolves the names and stuff after it receives
4810 the USERS list from the server when joining to the channel.
4812 * WHOIS and IDENTIFY commands has been changed to support multiple
4813 Client ID's per command. One can now search for multiple users
4814 in the network by sending only one WHOIS or IDENTIFY command.
4815 Changed the code and the protocol specifications.
4817 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4818 uses silc_server_command_whois_parse to parse the request. */
4820 * If normal server, do not parse the WHOIS and IDENTIFY requests
4821 before sending it to the router. Saves some time.
4823 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4825 * Fixed JOIN command on client library. Wrong number of arguments
4826 used to crash the client.
4828 * Added silc_server_channel_has_global function to check whether
4829 channel has global users or not.
4831 * Added silc_server_channel_has_local function to check whether channel
4832 has locally connected clients on the channel.
4834 * The silc_server_remove_from_one_channel now checks whether the
4835 channel has global users or not after given client was removed from
4836 the channel. It also checks whether the channel has local clients
4837 on the channel anymore. If it does not have then the channel entry
4838 is removed as it is not needed anymore.
4840 * The silc_server_notify now checks on JOIN notify whether the joining
4841 client is one of locally connected or global. If it is global then
4842 the channel has now global users on the channel and that is marked
4843 to the channel entry. Also, it now saves the global client to
4844 global list who is joining and JOINs it to the channel. This is
4845 for normal server, that is.
4847 Changed silc_server_send_notify_on_channel,
4848 silc_server_packet_relay_to_channel and
4849 silc_server_packet_send_to_channel check if we are normal server
4850 and client has router set (ie. global client) do not send the
4851 message to that client, as it is already routed to our router.
4853 * Implemented LEAVE notify type handling in silc_server_notify
4856 * Tested LEAVE command in router environment successfully. Tested
4857 with two routers, two servers and two clients.
4861 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4863 * Implemented SIGNOFF notify type handling in silc_server_notify
4866 * silc_server_remove_id now removes the client entry from all channels
4867 it has joined and thusly sends SIGNOFF notify type.
4869 * Rewrote the NAMES list generation in server by removing two excess
4870 loops. The lists are created now inside one loop.
4872 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * silc_server_remove_channel_user checks now also global list
4875 for channel and client.
4877 * silc_server_new_channel_user checks now both local and global
4878 list for channel and client. Fixed a bug in client id decoding.
4879 Used to decode wrong buffer.
4881 * silc_server_channel_message checks now both local and global
4882 list for channel entry.
4884 * Tested channel joining (hence JOIN) in router environment
4885 successfully. Tested with two routers, two servers and two
4888 * Tested channel message sending in router environment successfully.
4890 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4892 * Added silc_server_save_channel_key into server.[ch] to save the
4893 received channel key in Channel Key payload processing. It is
4894 also used in JOIN command reply handling.
4896 Equivalent function silc_client_save_channel_key added into
4897 client.[ch] into client library.
4899 * Changed JOIN command reply to send information whether the channel
4900 was created or not (is existing already) and the channel key
4901 payload. Changed protocol specs accordingly.
4903 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4904 the request was sent by ID and not by nickname. Crashed on
4907 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4910 now correctly save the received data.
4912 * silc_server_free_sock_user_data now notifies routers in the
4913 network about entities leaving the network.
4915 At the same time implemented functions silc_server_remove_id
4916 and silc_server_send_remove_id to receive and send REMOVE_ID
4917 packets. The packet is used to notify routers in the network
4918 about leaving entities. The ID removed will become invalid in
4921 * Added function silc_idlist_del_server into server. Removes and
4922 free's server entry from ID list.
4924 * silc_server_private_message function now checks, if we are router,
4925 that the destination ID really is valid ID, naturally.
4927 * In router when NEW_ID packet is received (for new client) the
4928 hash of the Client ID is saved in the ID Cache but the
4929 client->nickname is set to NULL, instead of putting the hash
4932 IDENTIFY command now also checks that client->nickname must be
4933 valid. If it is not if will request the data from the server who
4934 owns the client. Added new function
4935 silc_server_command_identify_check.
4937 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4938 to set the command to already allocated Command Payload.
4940 * Tested private message sending in router environment with two
4941 routers, two servers and two clients. Fixed minor bugs and now
4944 * Fixed segfault from client's NAMES command. Used to crash if
4947 * Forwarded packets must not be routed even if it is not destined
4948 to the receiver. Changed server code comply with this.
4950 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Added `require_reverse_mapping' boolean value to ServerParams
4953 structure. If TRUE (not default) the server will require that
4954 the connecting host has fully qualified domain name.
4956 If the reverse mapping is not required and hostname could not be
4957 found the IP address is used as hostname.
4959 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4961 * Implemented version string checking to both client and server.
4962 The check is incomplete currently due to the abnormal version
4963 strings used in development version of SILC.
4965 * Changed all command functions in server to use the new
4968 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4970 * Changed char *data to unsigned char *data in ID Cache system to
4971 support binary data as ID Cache data. Changed code to support
4972 binary data in lib/silccore/idcache.c.
4974 * Renamed silc_server_packet_relay_command_reply to
4975 silc_server_command_reply as it is normal packet receiving
4976 function. Rewrote the function to accept command replys for
4977 servers and not only for clients.
4979 * Mark remote router always as registered server if we are connecting
4980 to it. Otherwise, commands sent by the router to us are ignored.
4982 * All ID List find routines now returns the ID Cache Entry pointer
4983 as well if requested.
4985 * WHOIS command works now in router environment, tested with two
4986 routers, two servers and two clients.
4988 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4989 in router environment (as it is almost equivalent to WHOIS) but
4990 hasn't been tested thoroughly. Added new functions:
4992 silc_server_command_identify_parse
4993 silc_server_command_identify_send_reply
4994 silc_server_command_identify_from_client
4995 silc_server_command_identify_from_server
4997 * Disabled route cache adding because adding two different ID's with
4998 same IP replaces the old cache entry thus giving wrong route.
4999 The entry->router->connection is always the fastest route anyway
5000 so route cache may not be needed. Of course, new routes maybe
5001 established after receiving the ID when the entry->router->connection
5002 might not be anymore the most optimal.
5004 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Add route cache for received ID for fast routing.
5008 * Added silc_server_packet_route to route received packet on router
5009 that is not destined to us.
5011 * Renamed silc_server_get_route to silc_server_route_get.
5013 * Added id_string and id_string_len fields into SilcServer to
5014 include encoded ServerID for fast comparing without excess
5015 encoding of the ID's.
5017 * Cleaned up WHOIS command on server side. Added following static
5020 silc_server_command_whois_parse
5021 silc_server_command_whois_check
5022 silc_server_command_whois_send_reply
5023 silc_server_command_whois_from_client
5024 silc_server_command_whois_from_server
5026 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5027 arguments in command replies. All command functions should be
5028 updated to use this macro.
5030 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Minor typo fixes on command reply handling on server.
5034 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Added silc_server_command_add_to_channel internal routine to add
5037 the client to the channel after router has created the channel and
5038 sent command reply to the server.
5040 * Added generic silc_server_send_command to send any command from
5043 * Use static buffer with ID rendering instead of duplicating data.
5045 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed a channel user mode bug when joining to a channel server gave
5048 everybody channel founder rights, oops.
5050 * We mark ourselves as the router of the incoming server connection
5051 if we are router ourselves. This way we can check in some packet
5052 sending functions whether it is locally connected server. For
5053 incoming router connections we put NULL.
5055 * For router sending packets locally means now always sending the
5056 packet cell wide; to local clients and local servers. For normal
5057 server sending packet locally means sending it to only local
5060 * Fixed the JOIN command to really work in router environment. If the
5061 channel is created it is always created by the router. Router is
5062 also responsible of making the initial joining to the channel,
5063 sending JOIN notify to the sending server and distributing
5064 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5065 does not exist server doesn't do anything else but forward the
5066 command to the router which performs everything.
5068 * Added silc_server_send_channel_key function to send the Channel Key
5071 * Added silc_server_create_channel_key to create new channel key. The
5072 channel key is now re-generated everytime someone joins or leaves
5073 a channel, as protocol dictates. Note: channel->key_len is the
5076 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5078 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5079 packet_receive.[ch] to separate packet sending and receiving
5080 routines. The server.[ch] now includes everything else including
5081 actual packet processing (writing and reading data) and other
5084 Renamed silc_server_private_message_send_internal to
5085 silc_server_send_private_message. The routine is still though
5086 used only to relay private messages as server does not send
5087 private messages itself.
5089 Renamed silc_server_new_channel to silc_server_create_new_channel
5090 and added new function sicl_server_new_channel that handles the
5091 incoming New Channel packet. Added also new sending function
5092 silc_server_send_new_channel to send New Channel Payload.
5094 * Added new function silc_server_notify to process incoming notify
5095 packet to the server/router. Server may then relay the notify
5096 to clients if needed.
5098 * Added new function silc_server_new_channel_user to process incoming
5099 New Channel User packet. Router will redistribute the packet and
5100 send JOIN notify to its local clients and locally connected servers
5101 if needed. Normal server will send JOIN notify to its local client
5102 on same channel when received this packet. Added also corresponding
5103 sending function silc_server_send_new_channel_user to sent the
5106 * Added boolean route argument to send_notif_to_channel and
5107 packet_send_to_channel functions to attempt to route the packet
5108 if it is TRUE and send only locally if it is FALSE.
5110 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * silc_server_replace_id now broadcasts the received replace ID
5113 packet if it is not broadcast packet already. The router must
5114 broadcast to inform other routers about changed ID.
5116 * Added backpointer to server's router into SilcServer context in
5117 silcd/server_internal.h.
5119 * Fixed silc_server_packet_broadcast to send correct broadcast
5122 * The channel key is now distributed to the local client as soon
5123 as it is received from the router (in router environment) so that
5124 no other packet may be sent for the channel until client has
5127 * silc_server_remove_channel_user now broadcasts the received
5128 Remove Channel User packet if it is not broadcast packet already.
5129 The router must broadcast to inform other routers about removed
5132 * Added users field into SilcPacketContext that is a reference count
5133 of the context. One can increase the reference count by calling
5134 silc_packet_context_dup which is now changed to just increase the
5135 reference count instead of duplicating the data. The reference
5136 count is decresed by calling silc_packet_context_free that will
5137 free the data after the reference count hits zero.
5139 For now on the packet context and everything allocated into it
5140 (including the raw packet from network) must be freed by calling
5141 the new silc_packet_context_free function. Added also new function
5142 silc_packet_context_alloc that must be used now to allocate the
5143 context. This also means that if a routine is asynchronous from
5144 silc_[client/server]_packet_parse_type the packet context must
5145 be duplicated by calling silc_packet_context_dup. Otherwise it
5146 gets free'd after silc_[client/server]_packet_parse_type returns.
5147 Also, one must remember that if packet is duplicated then its
5148 reference count must be decresed by calling the free function as
5149 many times as it was duplicated.
5151 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5152 from both client and server.
5154 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * Made joining to a channel working in router environment.
5158 * Cleaned up JOIN command on server side and create function
5159 silc_server_command_join_channel internal routine to make the
5162 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Changed silc_command_pending list to SilcDList. Also, added
5165 `ident' field to SilcServerCommandPending structure to identify
5166 the reply and to call correct callback.
5168 Added silc_server_command_pending_check function to replace the
5169 corresnponding macro. The silc_command_pending list is not
5172 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5173 to set identifier to previously allocated Command Payload. It
5174 is used to set identifier for command when resending Command
5177 * Added silc_command_payload_encode_payload to encode Command
5178 Payload buffer from SilcCommandPayload structure.
5180 * Added silc_argument_payload_encode_payload to encode Argument
5181 payload buffer from SilcArgumentPayload structure.
5183 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5185 * Changed WHOIS command to support router connection on server side.
5186 The whois request is always sent to router unless the server is
5187 standalone server. After server has received the reply from the
5188 router will it send the reply to the client.
5190 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5191 broadcast received broadcast packet. The function is used only
5192 by router. The broadcast packet is always sent to the router's
5195 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5196 render given ID to printable string, for log files for example.
5198 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Made basic router to router connections working. At least they
5201 can now connect to each other but nothing really works the way
5202 they are supposed - yet.
5204 * Added new initiator token to RouterConnection configuration
5205 file in silcd/serverconfig.[ch]. It is used to tell whether we
5206 are the initiator to the remote router or whether we'll expect
5207 the other end to connect.
5209 * Moved registering of listener task to silc_server_init, hence
5210 the server starts listenning as soon as it is run, even if it
5211 does not have connections to other routers. Let's see how well
5214 * Changed default connection retry timeouts for more suitable in
5217 * Removed cipher and such arguments from silc_idlist_add_client
5218 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5219 Added new function silc_idlist_add_data to add the keys and stuff
5222 * Added SilcIDListData structure and added it to SilcClientEntry
5223 and SilcServerEntry as their first field in the structure. This
5224 way we can explicitly cast the ID entries to the SilcIDListData
5225 structure and get common data for the entries. In past, we had
5226 to first check what type of connection it is and then cast it to
5227 correct ID entry type. Now, we can directly cast the opaque
5228 pointer to the SilcIDListData (no matter what ID entry it actually
5229 is) and get the data needed.
5231 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5234 in some circumstances even if threre were timeout tasks, though not
5235 IO tasks, but tasks anyway. Now fixed.
5237 * Defined SilcServerConnection structure to hold connection specific
5238 stuff about directly connected servers and routers. The definition
5239 is currently in silcd/server_internal.h. I thought about having
5240 a bit more important role fro this struct but for now it is used
5241 only when connecting to other server (or router actually).
5243 * Added connecting retry support in server when connecting to
5244 router(s). The retry feature implement exponential backoff
5245 algorithm. Also, added SilcServerParams structure to hold default
5246 parameters for server. For now, it include these retry settings
5247 and are hard coded. After server is moded to be as Silc Server
5248 Library this structure will be more important.
5250 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5252 * Changed client librarys channel->clients table to SilcList and
5253 changed code accordingly.
5255 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Changed client's channel table to SilcList and changed code
5258 accordingly. Also changed SilcChannelClientEntry to include back-
5259 pointer to the channel so that client entry can use that structure
5260 as list as well and we have fast cross-reference to the channel.
5261 This change dramatically decreased the complexity of channel
5262 handling with client entry and vice versa (removed one extra
5263 loop when searching for channel entry from many functions).
5265 * Changed server->sim from table to SilcDList and changed code
5268 * NAMES command can now be used from user interface. It will show
5269 the user list on the channel, neatly.
5271 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5272 Code now saves realname of the user if it becomes available.
5274 * Renamed configure.in to configure.in.pre and made ./prepare
5275 script to automatically add correct version string to
5276 configure.in which it creates from configure.in.pre.
5278 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * NAMES command reply now shows users mode with the nickname when
5283 * Moved silc_client_ch[u]mode[_char] functions from
5284 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5285 place sucks, they are utility functions and should be in some
5288 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5290 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5293 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Added TRQ (efficient deque and list library) into lib/trq. This is
5298 a very good list library that is currently used in the SILC. Defined
5299 SilcList API over the library because I didn't like the API very
5300 much. See lib/trq/silclist.h for the API and examples of how to
5301 use the API. Fixed various places in the code to use the new
5302 SilcList API. The SilcList is meant for lists that has a structure
5303 already defined as a list. It is not suitable to add just some
5304 context to the list (in TRQ, the context is the list actually).
5306 So, I defined SilcDList that can be used for the purpose where
5307 predefined list structure does not exit. This can be used as
5308 such list. Now some context just can be added to the SilcDList.
5309 Currently this list is not used in the SILC just yet, though there
5310 are a lot places where this can replace dynamically allocated
5311 tables and I will fix these places, later, to use SilcDList.
5312 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5313 and use TRQ internally).
5315 Also fixed some annoying warning messages that the original TRQ
5316 code generated. Also minor changes to TRQ's Makefile.in.
5318 * Added support for querying by Client ID to both WHOIS and
5319 IDENTIFY commands into server, as required by the protocol.
5321 * Removed method function pointers from SilcBuffer structure. They
5322 weren't used to anything and just increased the context size for
5323 no good reason. This change also made silc_buffer_alloc and
5324 silc_buffer_free functions inline functions.
5326 * Disabled command flooding detection support until it's fixed so
5327 that it accepts commands in but does not execute them more than once
5330 * Added silc_net_localhost(), to return local hostname, into
5331 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5332 that must be initialized before calling silc_client_init.
5334 * Added new function: silc_server_send_notify_on_channels to send
5335 notify messages to all channels client has joined. It is assured
5336 that the message is sent only once per client.
5338 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5339 lib/silcutil/silcutil.[ch] as silc_format function. The new
5340 function is generic and is used by server as well, not only by
5341 the logging routines.
5343 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5344 the provided version string was not acceptable. Added new function:
5345 silc_ske_check_version into lib/silcske/silcske.h. The function
5346 must be implemented by the application (client or server) and it
5347 does not reside in the SKE library. The function checks the version
5348 string remote end sent.
5350 * Added back pointers (to opaque context and to SilcSocketConnection)
5351 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5353 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5354 duplicate packet context structure.
5356 * Changed `notify' client operation to send same arguments as client
5357 receives from server except for ID's. ID's are mapped to correct
5358 ID entry and that is returned. Also, if channel entry is not sent
5359 by server but the notify is for channel the channel entry is sent
5360 to application (otherwise application doesn't know that it is for
5361 channel (library gets it from packet's Destination ID)).
5363 * Added silc_client_remove_from_channels into client library to
5364 remove a client from all channels it has joined to. Used when
5365 received SIGNOFF notify from server. Added also new function
5366 silc_client_replace_from_channels to replace old ID entry with
5367 new ID entry on all channels. Used when received NICK_CHANGE
5370 * Fixed ID Cache list handling in silc_idlist_get_client in
5371 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5372 to get (or query) client by ID.
5374 * Updated TODO list.
5376 * Added connection authentication status message defined by the
5377 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5378 support for these into the code in client and server side.
5380 * Added generic function silc_client_send_command to send any command
5381 with variable argument list. Application should use this function
5382 to send commands if the command functions provided by the library
5383 does not suite for the application's user interface needs.
5385 * Added new `failure' client operation. Application is notified about
5386 received failure packet if client is executing a protocol. In this
5387 case the protocol's execution has failed.
5389 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5390 is required by the protocol.
5392 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5393 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5396 * Added status flag to SilcSKE object to indicate realtime status
5397 of the SKE protocol.
5399 * Application receives now exactly same command reply arguments as
5400 the library receives from server. However, if ID is received the
5401 corresponding ID entry is returned to the application (eg. Client
5402 ID is mapped to correct SilcClientEntry entry and that is returned).
5403 Changed command_reply client operation due to this change.
5405 * Changed all ID's in commands and in command replys as ID Payloads.
5406 Change affected both client and server side codes.
5408 All ID's sent in SILC network (with execption of ID's in SILC
5409 Packet header) are sent in ID Payload to support variable length
5412 * Server now notifies nick changes and notifies all clients on
5413 the channels about the new nickname (about the new Client ID,
5416 * Implemented CMODE command to change channel modes. Supports all
5417 channel modes defined by the protocol specs except ban and invite
5418 lists. (Also, private channel key mode is supported but support for
5419 setting private channel key in client is missing, thus, this mode
5420 has no effect on client side (except that server requires that the
5421 client uses private channel key and normal channel traffic does not
5424 Also, invite mode works per se, but INVITE command does not work
5425 yet correctly, so you can set channel as invite only channel but
5426 inviting clients to the channel does not work (it is yet to be
5427 thought what's the best way to do it).
5429 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5430 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5431 Implemented CUMODE command to change user's mode on the channel.
5432 Supports all modes defined by the protocol specs.
5434 * Added NAMES command reply to return users modes on the channel.
5436 * Removed unnecessary and slow ciphers from lib/silccrypt.
5438 * Set SO_KEEPALIVE option to connection sockets by default.
5440 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5442 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5443 redefined the Notify Payload into protocol specs.
5445 * Added silc_id_payload_parse_id to get ID directly from raw
5448 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5451 accept searching by Client ID as well.
5453 * Added support for LEAVE and SIGNOFF notify types in client library.
5455 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5456 to parse ID Payload from raw data.
5458 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Added flags parameter into silc_ske_assemble_security_properties
5461 function in lib/silcske/silcske.[ch].
5463 * Changed notify client operation to fit better for notify messages
5464 sent by server. The notify payload received from server is now
5465 passed to the application (after parsing it to SilcNotifyPayload).
5466 It is application's responsibility to retrieve the arguments
5467 from the payload and show the message the way it wants. The message
5468 sent by server is implementation specific.
5470 * Changed public keys to comply with the protocol specification.
5471 Old public keys are not supported anymore and are not compatible.
5473 * Removed nickname from Channel Payload as the latest draft removed
5474 it. The client must resolve the nickname from the NAMES command
5475 reply received when it joined the channel.
5477 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5479 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Fixed some errors in protocol specification drafts.
5483 * Created lib/silccore/silcnotify.c to implement Notify Payload
5484 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5485 generic payloads described by protocol specifications. The file
5486 includes implementations for ID Payload and Argument Payload.
5488 * Changed Command Payload implementation to use the new Argument
5489 Payload. Changed command_xxxx_payload to command_payload_xxxx
5490 to comply with SILC coding conventions.
5492 * Added suppport for Argument Payload handling in Notify Payload
5493 implementation as protocol requires it. Added the new support
5494 into server and client lib as well.
5496 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Added support for multiple nicknames on same channel. [n] is
5499 added locally to the nickname if there are more than one same
5500 nicknames on the channel.
5502 * Server now sends all nicknames that matched WHOIS request.
5503 Client also shows the list received from server.
5505 * Added TOPIC command to client side. User can now set and show
5506 current topic on channel.
5508 * Added MOTD command to client and server. Also, server sends the
5509 motd when client connects to the server.
5511 * Changed version strings to comply ISO 8601.
5513 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Fixed protocol error handling in client library. It should now
5516 cope even if the SKE fails for some reason.
5518 * Made new protocol specification drafts for submitting to IETF.
5520 * Implemented TOPIC command to server in silcd/command.c.
5522 * Added two new notify types into lib/silccore/silcnotify.h:
5523 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5524 notify nickname change and topic setting/change on a channel.
5526 * API change of command_reply operation in client library. The
5527 application gets now the status type received from server as well.
5529 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5533 * Cras fixed and optimized the packet handling even further and
5534 it should work now. Minor change to the prototype of function
5535 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5537 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Added new function into lib/silcutil/silcschedule.[ch]:
5540 silc_schedule_with_fd to select() a specified fd. The function
5541 returns after timeout expires or data arrives or goes. The
5542 function is used by packet routines to wait that all data is
5543 received from network.
5545 * Fixed data reading from network in lib/silccore/silcpacket.c.
5546 The code now assures that all data is read from the fd and then
5547 continues packet processing. This was a bug fix since the code
5548 used to drop some data in some circumstances.
5550 * Added new function into lib/silcclient/client.[ch]:
5551 silc_client_start_key_exchange to start key exchange after
5552 connection has been established to server. The code internally
5553 now uses this funtion but its main purpose was to provide it
5554 for applications that perform their own connecting. After
5555 application has created a connection it merely calls this
5556 function to start the key exchange between client and server.
5557 The library takes care of everything else after that.
5559 Updated also lib/silcclient/README to explain the usage of
5562 * Do not send to application information that connection has
5563 been established. Application gets notified it by connect
5566 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Applied cras's patch to add silc_schedule_one function. The
5569 function runs scheduler once and returns.
5571 * Fixed the scheduler after cras messed it up. The timeout
5572 handling works now as it's supposed to work.
5574 * Added into lib/silccore/ silcnotify.h to include notify
5575 message types support. Changed silc_server_send_notify*
5576 functions, in server.[ch], to support those new notify types.
5577 Added the support for the notify types into client library,
5578 as well. Added new notify client operation into ops.h in
5581 * Changed silc_server_packet_send_to_channel to send normal
5582 packets instead of just channel message packets. The function
5583 is now used to send the notify packets to channels. It is not
5584 used to send channel message packets anymore, as server never
5587 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5588 va_arg()s as it seems to require it nowadays. I guess, if SILC
5589 is compiled with older va_arg() the new code should work anyway.
5591 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Splitted core library. Core library (lib/silccore) includes
5594 now only SILC protocol specific core (and common) components.
5595 Created new utility library (lib/silcutil) that includes more
5596 generic purpose stuff. The stuff for util library was taken
5597 from the old core library. This was minor and easy split.
5599 * Created SILC Client Library (lib/silcclient) that includes
5600 implementation of the SILC client without user interface. This
5601 was major move from silc/ directory. The code has been changed
5602 so that it is transparent towards the user interface. The
5603 silc/ directory includes now the same user interface as before
5604 and it uses the new client library. Read lib/silcclient/README.
5605 Basicly, the client library performs everything else related
5606 to SILC except user interface handling. Also, configuration
5607 files are considered to be part of user interface and library
5608 does not handle them.
5610 This change also changed a lot of structures, function naming etc.
5611 Most important change was that SilcClientWindow object was
5612 renamed to SilcClientConnection in the client library. Created
5613 also new file lib/silcclient/ops.h. Also added new files
5614 silc/local_command.[ch] and silc/client_ops.[ch].
5616 All these changes were made to make it easier for user interface
5617 designers to create what ever user interface for the SILC client
5620 It is also expected that the server will be moved to lib
5621 directory as well and SILC Server Library will be created;
5622 sometimes in the future.
5624 * Removed Local commands from lib/silccore/silccommand.h as
5625 they are application specific and new client library does not
5626 handle any of those anymore.
5628 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5629 old client implementation in silc/.
5631 * Added support for callback functions in SILC_LOG_* macros.
5632 Application can now set its own callbacks that will be called
5633 instead of using the default functions that will always print
5634 the debug messages to stderr (or stdout). Also, debugging can
5635 now be disabled by setting silc_debug to FALSE and re-enabled by
5636 setting it to TRUE. Note, that logging will still work even
5637 if debugging is disabled.
5639 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5640 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5641 silc_log_reset_debug_callbacks.
5643 * To enable debugging in silc client one must give now -d
5644 option on command line.
5646 * Changed silc_schedule_init to automatically allocate task queues
5647 if they are not allocated before calling it.
5649 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added GMP 3.1 into math library.
5653 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5656 a channel in SILC network. The packet is used by servers and
5657 routers to notify other routers that user has left a channel.
5658 This little feature was missing until now. Added the feature
5659 to protocol specification as well.
5661 Added functions: silc_server_send_remove_channel_user and
5662 silc_server_remove_channel_user into server.[ch].
5664 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5665 lib/silccore/silcpacket.h. However, they are not implemented
5668 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Fixed joining to a channel and sending channel messages
5671 between server and router. The channel message sending should
5672 now work inside a cell.
5674 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Fixed the private message sending between server and router.
5677 The private message sending should now work inside a cell.
5679 * Added silc_server_replace_id into server.[ch] to replace
5680 existing ID in the SILC network.
5682 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5683 and silc_idlist_replace_server_id into idlist.[ch] in server.
5685 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Fixed the server to server connections. Server can again now
5688 connect to router. Router to router connections probably does
5691 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Added dynamic protocol registering support. Now protocols can
5694 registered and unregistered on the fly. Patch by cras.
5696 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Added lib/contrib directory to hold routines that some platforms
5699 don't have but are needed by SILC.
5701 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5702 into lin/contrib to provide getopt() and getopt_long() for
5703 those who don't have it.
5705 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Added AWAY command to client. When away message is set and
5708 client receives a private message packet the client automatically
5709 replies to the sender with the away message.
5711 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5712 bug seemed to be the cause of recent problems when compiling
5715 * Added version detection support to SKE protocol specification
5716 and added the new changes to the SKE implementation as well.
5717 There were other minor changes in the SKE protocol as well.
5719 Many changes in lib/silcske/silcske.[ch] and in
5720 lib/silcske/payload.[ch].
5722 * Added ^U functionality, clear input line. Patch from cras.
5724 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Mainly small bugfixes on core library. Fixed some debugging
5727 logging and buffer overflow in silclog.c.
5729 * Updated config.sub and config.guess on the distribution tree.
5731 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Added command lagging support in server. Client may execute
5734 commands now only once in two seconds.
5736 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Optimized packet reception. MAC computation and checking is now
5739 also more optimized. A lot previously duplicated code is now
5740 used as generic by both client and server.
5742 * Fixed key pair generation in clientutil.c
5744 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5746 * Added into lib/silccore/silcbufutil.[ch] new function;
5747 silc_buffer_realloc.
5749 * Moved generic packet sending/encryption functions to
5750 lib/silccore/silcpacket.[ch] from client and server. Some
5751 rewriting of the functions.
5753 * Moved all generic packet reception/decryption functions to
5754 lib/silccore/silcpacket.[ch] from client and server. The
5755 packet processing is now much cleaner in both client and server.
5756 These were major changes in both client and server.
5758 * Created many common functions in server to do packet sending.
5759 Previously code were duplicated a lot, this has been removed
5762 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Rewrote major parts of the ID cache system. Don't know
5765 whether it is better now or not but at least the API is more
5768 * Major rewrite on ID cache stuff on client because of the ID
5769 cache API changes. Added idlist.c to client.
5771 * Also major rewrite on ID cache stuff on server as well.
5772 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5773 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5774 in hand, instead they are all put into the ID cache system now.
5775 All server_idlist_* routines uses ID cache now instead of
5776 traversing its own lists (those lists does not exist anymore).
5777 SilcIDList though still exists. Also, SilcXXXEntry's are
5780 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Finally made the SKE implementation compliant to the protocol
5783 specification. All mp integers are now binary encoded as
5784 opposed being HEX encoded.
5786 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5789 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5790 functions: silc_[encode/decode]_pem. Also added function
5791 silc_encode_pem_file to PEM encode with newlines ('\n') for
5794 * SILC public keys are now encoded either PEM or binary. Same
5795 option is for private keys as well. By default private keys
5796 are binary encoded and public keys PEM encoded. Silly HEX
5797 encoding were removed.
5799 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5800 function to create fingerprints.
5802 * Fixed a bug in SHA1; does not change the original data anymore.
5804 * Partly implemented INFO command on client and server side.
5805 Fixed CLEAR command. Changes to SERVER command; show current
5806 server(s) when giving command without arguments. Added
5807 VERSION command to client.
5809 * Added check to server that unregistered connections cannot
5810 execute commands (unless it is specificly allowed).
5812 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Fixed screen refresh.
5816 * Fixed channel joining bug from client. On some circumstances
5817 client tried to join to a channel it had already joined.
5819 * Added public key verification process into client's protocol.c.
5820 The client now verifies the public key from user and saves
5821 it into ~./silc/serverkeys/ directory.
5823 Added into: clientutil.[ch]: silc_client_verify_server_key.
5825 * Changed SKE protocol's silc_ske_initiator_finish function
5826 to accept callback function that verifies the received public
5827 key. Removed old silc_ske_verify_public_key function.
5829 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5832 silc_pkcs_private_key[_data]_set.
5834 * Made the password and public authentication more cleaner in
5835 server's protocol.c.
5837 * Removed historic and obsolete protocol `channel_auth' from
5838 both client and server.
5840 * Removed wrong way of sending command status messages from
5841 server to client in server's command.c. The old way violated
5842 protocol specification.
5844 Changes to silccore/silccommand.[ch]: removed
5845 silc_command_encode_status_payload -> not needed anymore,
5846 changed silc_command_encode_payload_va to accept extra
5847 argument on variable argument list. The argument type must
5848 now be provided to the function. Also, added new function:
5849 silc_command_encode_reply_payload_va which is same as
5850 normal command_encode_payload_va except command status type
5851 is provided as extra argument.
5853 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Added ~./silc directory handling. The directory includes the
5856 public and private keys for the client.
5858 Added silc_client_check_silc_dir, silc_client_create_identifier
5859 and silc_client_load_keys.
5861 * Implemented SILC protocol compliant public key. Added public
5862 and private key saving to and loading from files.
5864 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5865 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5866 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5867 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5868 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5870 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5871 silc_pkcs_load_[public/private]_key.
5873 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Added silc_server_get_route (route.[ch]) to get connection
5876 data for the fastest route for given ID.
5878 * Implemented INVITE command on client and server. The command
5879 were re-defined in the SILC Protocol Specification and the
5880 implementation now complies with the specification.
5882 * Implemented PING command on client and server.
5884 * Implemented NAMES command on client and server. The server side
5885 supports currently only normal server not router server yet.
5886 Some changes to NAMES definition in SILC protocol specification.
5888 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5890 * Implemented LEAVE command on client and server.
5892 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5893 again. This change was made to the protocol as well. Server
5894 should not violate the protocol specification anymore.
5896 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5899 was tested. SOCKS4 was not but should work anyway.
