78 preserve the WHOWAS info for the client. Affected file
81 * Fixed SERVER_SIGNOFF notify handling in the server. The
82 server is now able to process incoming SERVER_SIGNOFF notify
83 for a server that it doesn't even know about. It will remove
84 the clients provided in the notify. Affected file
85 silcd/packet_receive.c.
87 * Check for partial packet in data queue after every packet that

128 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
130 * Assure that silc_client_notify_by_server_resolve does not
131 resolve the client information multiple times. If it cannot
132 be found by the first it cannot be found at all. Affected
133 file lib/silcclient/client_notify.c.
135 * Fixed WHOWAS command reply calling. Affected file
136 lib/silcclient/command_reply.c.
138 * Removed all references to silc_idlist_get_client from the
139 Irssi SILC client since that call is internal call used by
140 the library. The Irssi SILC client will use now client
141 retrieval functions found in silcapi.h.
143 * Fixed a bug in resolving nickname info before sending
144 private message. It used freed memory. Affected file
145 irssi/src/silc/core/silc-servers.c.
147 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

260 * Redefined the SILC packet header to include the padding
261 length. Affected file lib/silccore/silcpacket.[ch].
263 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
264 length for maximum padding up to 128 bytes). Affected
265 file lib/silccore/silcpacket.h.
267 * Removed all backwards support for old 0.5.x MAC thingies.
268 The SILC packet header change makes it impossible to be
269 backwards compatible.
271 * Send the ENDING packet with timeout in the backup resuming
272 protocol. This is to assure that all routers has connected
273 to the primary router. Affected file silcd/server_backup.c.
275 * Changed the RNG to take the first IV from random data. It
276 used to take it from zero actually. Changed the RNG also
277 to use /dev/urandom during session. /dev/random is used
278 in initialization. Affected file lib/silccrypt/silcrng.[ch].
280 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
282 * Changed the SILC packet header to have the first two bytes
283 (the packet length) encrypted. Affected files aroung the
284 code tree, lib/silccore/silcpacket.[ch]. Removed the
285 SilcPacketCheckDecrypt callback. It is not needed anymore
286 since the silc_packet_receive_process will determine now
287 whether the packet is normal or special.
289 * Implemented the unidirectional MAC keys. Affected files
290 lib/silcske/silcske.c, silcd/protocol.c and
291 lib/silcclient/protocol.c.
293 * Implemented the packet sequence number to the MAC computation.
294 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
295 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
296 lib/silcclient/protocol.c.
298 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
300 * Allow backup router to announce servers. All servers
301 announced by backup router are added to the global list
302 automatically. Update hte server's socket to our primary
303 router also when backup router announces a server.
304 Affected file silcd/packet_receive.c.
306 * Do not update the client->router in the function
307 silc_server_udpate_clients_by_server if the client is on
308 global list. We might fail to find any specific server
309 for locally connected clients and local cell clients. They
310 should still use the `from' and not `to' as client->router.
311 This fixes backup router resuming protocol. Affected file
314 * Decrease channel statistics count only if the channel
315 deletion worked. Affected files are silcd/server.c and
318 * Added silc_server_update_servers_by_server to update origin
319 of all server entries. Used during backup router protocol.
320 Affected files silcd/server_util.[ch], silcd/server.c. and
321 silcd/backup_router.c.
323 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
324 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
325 silc_hmac_get_hash and silc_hmac_get_name. Affected file
326 lib/silccrypt/silchmac.c.
328 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Assure that router cannot reroute the same channel message
331 to the sender. Affected file silcd/packet_receive.c.
333 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
335 * Made better checks that the channel message is not sent
336 to the router it came from. Affected file is
337 silcd/packet_send.c. Fixed memory leak too.
339 * Announce informations for incoming router connection, but
340 only after checking if it is replaced by backup router.
341 Affected file silcd/packet_receive.c.
343 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
345 * Fixed the backup resuming protocol to work in multiple
346 router environment. Affected file silcd/server_backup.c.
348 * Route packet only to one router in the function
349 silc_server_packet_send_to_channel. Affected file is
352 * Fixed silc_server_send_notify_dest to set the broadcast
353 flag. Fixed the silc_server_send_notify_topic to actually
354 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
355 Affected file silcd/packet_send.c.
357 * Changed the SFTP Filesystem interface. Changed the
358 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
359 the filesystem operation function. The SilcSFTPFilesystem
360 is now a context that is allocated by all filesystem allocation
361 functions and it already includes the operations structure
362 and filesystem specific context. It is given as argument
363 now to the silc_sftp_server_start. This made the interface
364 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
365 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
367 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Changed the backup router adding and getting interfaces
370 in the server. The router that will be replaced by the
371 specified backup router is now sent as argument. Affected
372 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
375 * Added silc_net_addr2bin_ne to return the binary form of
376 the IP address in network byte order. Affected files
377 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
379 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
381 * Check for existing server ID in silc_server_new_server
382 and in silc_server_connect_to_router_final and remove the
383 old entry if it exists. Affected file silcd/packet_receive.c,

387 in upstream or downstream. Affected file is
390 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
392 * Wrote the definition of the backup resuming protocol to the
393 protocol specification.
395 * Removed one redundant channel key generation from normal
396 server during joining procedure. Removed one redundant
397 channel key sending from server to router during joining
398 procedure. Affected file silcd/command.c.
400 * Made minor bugfixes to the backup router resuming protocol.
401 Affected file silcd/server_backup.c, server.c.
403 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

406 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
409 * Implemented the backup resuming protocol that is used to
410 resume the primary router position in the cell after the
411 primary router comes back online. Affected files
412 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
413 and silcd/server_util.[ch].

421 send any data. Affected file silcd/packet_send.c.
423 * Assure that if outgoing data buffer is pending do not force
424 send any data. Affected file lib/silcclient/client.c.
426 * Implemented the backup router support when the primary router
427 goes down. The servers and routers can now use the backup
428 router as new primary router without loosing connectivity.
430 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
432 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
433 in the server to indicate disabled entry. All data read
434 from the connection will be ignored and no data is sent
435 for entry that is disabled. Affected files are
436 silcd/idlist.h, silcd/server.c.
438 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Created SFTP client and server test programs in the
441 lib/silcsftp/tests directory.
443 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Implemented memory filesystem (virtual filesystem) for
446 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
449 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
451 * Implemented the SFTP (SSH File Transfer Protocol) to the
452 lib/silcsftp. It includes SFTP client and SFTP server
455 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
457 * Moved lib/silccore/silcprotocol.[ch] to the
458 lib/silcutil library.
460 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
461 take variable argument list pointer as argument. Affected
462 file lib/silcutil/silcbuffmt.[ch].
464 * Added silc_buffer_set function that is used to set data
465 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
466 Affected file lib/silcutil/silcbuffer.h.
468 * Changed various routines in the core library to use the new
469 silc_buffer_set instead of allocating new buffer only for
472 * Added 64-bit value formatting and unformatting support to the
473 silc_buffer_[un]format routines. Affected file is
474 lib/silcutil/silcbuffmt.[ch].
476 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
477 to includes/bitmove.h.
479 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
481 * Fixed channel user mode saving in client library. Affected
482 file lib/silcclient/command[_reply].c.
484 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
486 * Defined the file transfer to the SILC Protocol. Added
487 new packet type SILC_PACKET_FTP and defined File Transfer
488 Payload. The mandatory file transfer protocol is SFTP
489 (SSH File Transfer Protocol). Affected file in addition
490 of the internet draft is lib/silccore/silcpacket.h.
492 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
493 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
494 is used as part of backup router protocol when the primary
495 router of the cell is back online and wishes to resume
496 the position as primary router.
498 * Redefined the MAC generation keys in the protocol. The
499 same key is not used anymore in both direction. Both
500 direction will now use different keys for sending and
501 receiving. This fixes a potential security flaw. This
502 change causes incompatibilities in the protocol.
504 * Redefined also the MAC computation from the packet.
505 An packet sequence number is now added to the MAC
506 computation. This prevents possible replay attacks against
507 the protocol. This change too causes incompatibilities
510 Added `sequence' field to the SilcPacketContext to hold
511 the current sequence number for the packet.
513 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
515 * Added `created' field to the SilcIDListData in the file
516 silcd/idlist.h to indicate the time when the entry was
519 * Added `created' field to the SilcChannelEntry too. Affected
522 * Added `creation_time' aguments to all the announcement functions
523 in the server. If it is provided then only the entries that
524 was created after the provided time frame are actually
525 announced. Affected file silcd/server.[ch].
527 * The protocol says that the Channel ID's IP address must be
528 based on the router's IP address. Added check for this in
529 the silc_server_new_channel when processing incoming New Channel
530 Payload. Affected file silcd/packet_receive.c.
532 * Print out the correct version with --version in SILC client.
533 Affected file irssi/src/silc/core/silc-core.c.
535 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

538 entry always, not just when the command is coming from client.
539 Affected file silcd/command.c.
541 * Added new function silc_server_packet_queue_purge to purge the
542 outgoing data queue to the network. After the function returns
543 it is guaranteed that the outgoing packet queue is empty.
544 Affected file silcd/packet_send.[ch].
546 * Purge the outgoing packet queue in the rekey protocol's final
547 callback to assure that all rekey packets go to the network
548 before quitting the protocol. Affected file silcd/server.c.
550 * Added silc_client_packet_queue_parse as similar function as
551 in server to the client library. The affected file is
552 lib/silcclient/client.c.
554 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Splitted silcd/server.c and created silcd/server_util.[ch]
557 for utility functions.
559 * Added new socket flag SILC_SF_DISABLED to indicate that the
560 connection is open but nothing can be sent to or received from
561 the connection. Affected file lib/silcutil/silsockconn.[ch].
562 The checking for disabled socket is checked in the low level
563 silc_socket_write and silc_socket_read functions.
565 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Allow only nicknames and channel names that fits into the
568 7-bit unsigned char ASCII set. Affected file silcd/command.c.
570 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
572 * When processing JOIN command reply in server check that if
573 the channel exists in our global list we'll move it the local
574 list. Affected file silcd/command_reply.c.
576 * Fixed the check whether client is joined on the channel already
577 in JOIN command. Affected file lib/silcclient/command.c.
579 * Fixed the JOIN command reply to check whether the channel
580 already exists. Affected file lib/silcclient/command_reply.c.
582 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
584 * Added silc_ske_status_string to map the SKE error numbers
585 to readable strings. The affected files are
586 lib/silcske/silcske[_status].[ch].
588 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
590 * Do not show the private channels on the WHOIS channel list
591 as it is not allowed by the protocol. The affected file is
594 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
596 * Assure that the packet length digged from the actual packet
597 is something sensible in the silc_packet_decrypt_rest_special
598 in lib/silccrypt/silcpacket.c.
600 * Free and NULL the allocated pointer in silc_hmac_alloc if
601 the HMAC allocation fails. The affected file is
602 lib/silccrypt/silchmac.c.
604 * Print the selected security properties to the log files in
605 the server. Affected file silcd/protocol.c.
607 * Add SKE's reference counter even if calling the completion
608 callback manually. Otherwise it goes negative, although it
609 does not cause any problems. The affected file is
610 lib/silcske/silcske.c.
612 * Remove the client entry with short timeout after giving the
613 KILL command. Affected file lib/silcclient/command.c.
615 * Fixed to send error reply in WHOIS and IDENTIFY commands in
616 case all found clients are already disconnected (WHOWAS would
617 found them) in the server. Affected file silcd/command.c.
619 * Update the last_receive (time of last data received) to be
620 updated only when received private or channel message so that
621 the idle time showed in WHOIS makes more sense.
623 * Added boolean field `valid' in to the SilcClientEntry in the
624 client library to indicate whether the entry is valid or not.
625 This fixes the nickname change bug on channel when changing
626 the nickname to be same than the old (like nick to Nick) the
627 nickname formatter doesn't set the new nick anymore to Nick@host.
628 Affected file lib/silcclient/idlist.[ch].
630 * Now actually fixed the nickname changing on disconnection.
631 Added new function silc_change_nick to the Irssi SILC Client.
632 Affected file irssi/src/silc/core/client_ops.c,
633 irssi/src/silc/core/silc-nicklist.[ch].
635 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
637 * Check that the public key exists in the GETKEY command before
638 trying to encode it. Affected file silcd/command.c.
640 * Print some notifications on received public keys with GETKEY
641 command in the Irssi SILC Client. Affected files are
642 irssi/src/fe-common/silc/module-formats.[ch],
643 irssi/src/silc/core/client_ops.c.
645 * Use IDENTIFY command to resolve the server information in the
646 GETKEY command instead of INFO command. Affected file
647 lib/silcclient/command.c.
649 * All command reply functions in the client library now calls
650 the pending command reply callbacks even if an error has
651 occurred. The server has done this a long time and now it was
652 time to move the client library to this as well. Now all
653 errors can be delivered back to the pending command reply
654 callbacks if necessary. Affected files are
655 lib/silcclient/command[_reply].[ch].
657 * Change the nickname on disconnection back to the username
658 because in reconnect the server will enforce it to it anyway.
659 Affected file irssi/src/silc/core/silc-servers.c.
661 * Fixed a config file parsing bug in the Irssi SILC client.
662 Affected file irssi/src/silc/core/clientconfig.c.
664 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
666 * When printing the channel mode on JOIN, verify that the
667 channel key and channel's HMAC are valid. Affected file
668 irssi/src/silc/core/client_ops.c.
670 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
672 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
673 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
674 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
676 * Removed channel key rekey task deleting from the function
677 silc_server_save_channel_key. Affected file silcd/server.c.
678 Added explicit timeout task context instead that is used to
679 delete the task if we are registering a new task before the
680 new task has elapsed.
682 * When channel key rekey occurs the client library now saves
683 the old channel key for a short period of time (10 seconds) and
684 is able to use it in case some is still sending channel
685 messages encrypted with the old key after the rekey. Affected
686 file lib/silcclient/[idlist.h|client_channel.c].
688 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
690 * Added check to the silc_server_new_id_real to not accept
691 new ID if it is the sender's own ID. Affected file is
692 silcd/packet_receive.c.
694 * Assure that we do not announce ourself or the one we've
695 sending our announcements when we're router and are announcing
696 servers to our primary router. Affected file silcd/server.c.
698 * Fixed silc_server_command_identify_check_client to assemble
699 correct WHOIS packet. It send corrupted WHOIS packet and
700 caused problem with router to router connections. Affected
701 file silcd/command.c.
703 Fixed also silc_server_command_whois_check the same way
704 as for the IDENTIFY command.
706 * Added new SilcIDListStatus to the server in the SilcIDListData
707 structure. The status now includes the current status of
708 the entry (like registered, resolved etc.). Affected file
709 silcd/idlist.[ch]. Defined a bunch of different status types
710 as well. This replaced the old boolean registered field as well.
712 Added resolve_cmd_ident field to the SilcClientEntry structure
713 too so that if the entry is for example being resolved so
714 another command may attach to the same pending command reply
715 without requiring to resolve the same entry again. This concept
716 should optimize the WHOIS and the IDENTIFY resolving under
717 heavy load by taking away unnecessary resolving for entries
718 that are being resolved already.
720 Added support for adding multiple pending commands for one
721 command idenfier. Affected file silcd/command[_reply].[ch].
723 * Fixed WHOIS and IDENTIFY save to remove the cache entry
724 before deleting the data. Otherwise the hash table will have
725 freed data in comparison functions. Affected file is
726 silcd/command_reply.c.
728 * Fixed silc_idlist_replace_client_id to add the new entry to
729 the cache with NULL nickname. Otherwise there will be invalid
730 memory as the nickname after the nickname is freed. Affected
731 file silcd/packet_receive.c.
733 * Fixed the silc_idlist_get_clients_by_hash. The entries was
734 saved into wrong slots because the previous number of entries
735 was not taken into account. Affected file silcd/idlist.c.
736 Fixed same thing in silc_idlist_get_clients_by_nickname too.
738 * If we are router and we receive JOIN notify to a channel that
739 does not have any users then notified client is marked as the
740 channel founder, as it is it. The affected file is
741 silcd/packet_receive.c
743 * Added to the extended hash table API's table_del_*ext functions
744 the destructor as argument too, so that the caller can decide
745 which destructor to use or whether to use destructor at all.
746 Affected file lib/silcutil/silchashtable.[ch].
748 * Fixed ID Cache purging. It actually deleted the entries from
749 the hash table after the data was freed. The hash table ended
750 up comparing freed memory. The affected file is
751 lib/silccore/silcidcache.c.
753 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Fixed Irssi SILC client's KILL command's HELP syntax.
757 * The USERS command now resolves the detailed user information
758 if the userinfo field is missing. Affected file is
759 lib/silcclient/command_reply.c.
761 * Do not print error in silc_file_read if the read file does
762 not exist. Just silently return NULL. Affected file is
763 lib/silcutil/silcutil.c.
765 * Fixed the silc_log_output to not wine about NULL filename
766 and to not create some bogus " " filename. Affected file is
767 lib/silcutil/silclog.c.
769 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
771 * Fixed various printing bugs on the user interface in the
772 Irssi SILC Client. Minor changes that were forgotten from
775 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
777 * Fixed the configure.in.pre and the compilation and distribution
778 environment to support the new autoconf 2.52. That version is
779 now required to compile the CVS trunk.
781 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Renamed function silc_parse_nickname to silc_parse_userfqdn
784 to generally parse user@fqdn format strings. Affected file
785 lib/silcutil/silcutil.c.
787 * Added nickname_format and nickname_force_format fields to the
788 SilcClientParams structure. The first one defines the format
789 for the nicknames that the library will enforce if the receives
790 multiple same nicknames. The second one is boolean value and
791 can be used to force the library to always enforce the format
792 to the nicknames regardles whether there are multiple nicknames
793 or not. This configurable formatting was employed to flexibly
794 support accessing multiple nicknames from the user interface.
795 The userinterface can now set the nicknames to what ever format
796 they prefer. Affected file lib/silcclient/silcapi.h.
798 Added function silc_client_nickname_format to the file
799 lib/silcclient/idlist.c. It performs the nickname formatting.
801 Added new field `hostname´ to the SilcClientEntry context.
802 It holds the hostname of the client. Affected file is
803 lib/silcclient/idlist.h.
805 * Irssi SILC Client sets the nicknames in nick@hostn format.
806 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
807 irssi/src/silc/core/silc-core.c.
809 The WHOIS printing now also shows both the real nickname and
810 the formatted nickname so that user knows how to access the
811 user if there are multiple same nicknames cached. Affected
812 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
813 printing formatting too to take the hostname now as a separate
814 argument. The Affected file is
815 irssi/src/fe-common/silc/modules-formats.[ch].
817 * Changed the silc_client_get_clients_local to accept the formatted
818 nickname as argument. It accepts the real nickname too but the
819 formatted nickname can be used to find the true entry from
820 multiple entries. Affected file lib/silcclient/silcapi.h and
821 lib/silcclient/idlist.c.
823 * Added nickname_format_parse field to the SilcClientParams.
824 It is a callback function provided by the application to parse
825 the nickname out of the formatted nickname string. The library
826 calls it to get the nickname from the formatted string. Since
827 the application generally knows better the format of the nickname
828 string it parses it instead of the library, even though library
829 encodes the formatted string. If the callback function is not
830 provided then the library will use the string as is. The
831 affected file is lib/silcclient/silcapi.h.
833 * All the nickname strings passed to the client library in
834 commands are now expected to be formatted nickname strings.
835 If the command does not support the formatted nickname string
836 it will assume that the sent string is the actual nickname.
837 Affected file lib/silcclient/command.c.
839 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Added public key authentication support to OPER and SILCOPER
842 commands in the client library. Affected file is
843 lib/silcclient/command.c.
845 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Changed the get_auth_methdod client operation to be asynchronous.
848 It can be async if the application resolves the authentication
849 method from the server during the negotiation. Added new
850 SilcGetAuthMeth completion callback that the application will
851 call after resolving the authentication method.
853 Added function silc_client_request_authentication_method that
854 the application can use to resolve the authentication method
855 from the server. Added also SilcConnectionAuthRequest callback
856 that the library will call after the server has replied. The
857 application can call this function if it does not know the
858 current authentication method.
860 Affected files are lib/silcclient/client.c and
861 lib/silcclient/silcapi.h.
863 * The Irssi SILC client now automatically resolves the authentication
864 method incase any configuration information is not present (and
865 currently there never is). The affected file is
866 irssi/src/silc/core/client_ops.c.
868 * Fixed public key authentication from the client library.
869 Affected file lib/silcclient/protocol.c. Changed also the
870 protocol specification about the public key authentication in
871 the connection authentication protocol. The actual data to be
872 signed is now computed with a hash function before signing.
874 * Fixed the public key authentication from the server as well.
875 Affected file silcd/protocol.c.
877 * Removed the mlock()'s from the memory allocation routines.
878 Affected file lib/silcutil/silcmemory.c. The ./configure does
879 not check anymore for the mlock(). Affected file is
882 * Fixed USERS command in server to allow the execution of the
883 command for private and secret channels if the client sending
884 the command is on the channel. Affected file silcd/command.c.
886 * Fixed silc_client_get_clients_local to return the clients
887 count correctly. It could return wrong value. Affected file
888 lib/silcclient/idlist.c.
890 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
893 types. The assembler optimizations seemed not to like 64-bit
894 data types. The assmebler optimizations thus are now enabled
895 also for BSD systems as opposed to only enable them for Linux.
897 * Do not check for threads at all on BSD systems. Affected
898 file configure.in.pre.
900 * Removed -n and -h options from the Irssi SILC Client since
901 they are not used in silc.
903 * Fixed the prime generation to assure that the first digit
904 of the generated random number is not zero since our conversion
905 routines does not like number strings that starts with zero
906 digit. If zero digit is seen the random number is regenerated.
907 This caused some corrupted RSA keys when the zero first digit
908 was met. Affected file lib/silcmath/silcprimegen.c.
910 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Fixed WIN32 configuration in the ./configure script.
913 Fixed to include xti.h on environments that has it.
914 Patches by Carsten Ilchmann and andrew.
916 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Changed the silc_id_create_client_id to be collision
919 resistant. It is now assured that there cannot be created
920 two same client ID's. I suspect that some weird bugs in
921 the server were actually caused by duplicate Client IDs.
922 Affected file silcd/serverid.[ch]. A router receiving
923 new ID now also assures and informs the sending server
924 if the ID caused collision.
926 * Changed the silc_id_create_channel_id to also assure that
927 there are no collisions.
929 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Statement about ignoring the Mutual Authentication flag when
932 performing rekey with PFS was a bit misleading. It is ignored
933 if it was set in the initial negotiation, it cannot be even
934 set in the rekey. Fixed in the ke-auth draft. Started the
935 new versions of the protocol drafts in the doc/.
937 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
939 * Fixed a bug in silc_client_command_identify_save when saving
940 new channel information. The channel name was no duplicated
941 and caused crash on exit. Affected file is
942 lib/silcclient/command_reply.c.
944 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
946 * Fixed the getkey command handling in the server. Send just
947 empty OK reply to the sender if the key could not be fetched
948 (but everything else was ok, like the key just was not available).
949 Changed the public key parameter to optional in the protocol
950 specs so that empty OK reply can be sent. Affected file
953 Added a message to Irssi SILC client to tell to user if the
954 server did not return a public key.
956 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * Fixed a channel key regeneration bug. It registered new
959 timeout tasks exponentially until all system resources were
960 used. Affected file silcd/server.c.
962 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Added the SILC Document generator to the scripts/silcdoc.
965 It can be used to generate the Toolkit Reference Manual out
966 of the source tree. Internally it will also use the RoboDoc
967 generator now imported in util/robodoc.
969 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
971 * Added couple of return's in rekey protocol if error orccurred
972 during the protocol. The execution must be terminated.
973 Affected file silcd/protocol.c. Also, terminate the protocol
976 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
978 * The client's Client ID was created initally from the wrong
979 nickname (it could have been in format nick@host) in the
980 silc_server_new_client. Affected file silcd/packet_receive.c
982 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Added some SILC_LOG_ERROR's to various error conditions
985 if client could not be added to ID cache. Affected files
986 silcd/packet_receive.c and silcd/server.c.
988 * When client's sock->user_data is freed, NULL also the
989 client->router and client->connection pointers. Added check
990 for these pointers being NULL to various places around the
991 code. Affected file silcd/server.c.
993 * Added client->data.registered == TRUE checks to various
994 places around the code to assure that unregistered client's
995 are not handled when it is not allowed. Affected file
998 * Added `bool registered' fields to all
999 silc_idlist_[server|client]_get_* routines to indicate whether
1000 the fetched client needs to be registered or not. Affected
1001 file silcd/idlist.[ch].
1003 * Add your own entry as registered to the ID cache in the
1004 server. Affected file server.c.
1006 * Fixed a bug in silc_server_new_server. The SilcServer was
1007 set as the new server's context instead of SilcServerEntry.
1008 This naturally caused some weird bugs.
1010 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1012 * Do not delete the channel rekey task when adding it
1013 for in silc_server_create_channel_key.
1015 * Changed the silc_server_create_channel_key to return
1016 TRUE or FALSE to indicate the success of the channel key
1019 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Fixed MSVC++ project files and added missing files to
1022 Makefiles under win32/.
1024 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1026 * Do not add TCP_NODELAY flag if the operating system
1027 does not have it defined. Affected files are
1028 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1030 * Fixed buffer overflow from Irssi SILC Client. Affected
1031 file irssi/src/fe-common/core/themes.c.
1033 * Fixed double free in client library in the file
1034 lib/silcclient/client.c when disconnecting from server.
1036 * Applied double free patch from cras to Irssi SILC client.
1037 Affected files irssi/src/core/[modules/expandos].c
1039 * Fixed the disconnection handling to Irssi SILC Client.
1040 The application must call silc_client_close_connection
1041 in ops->connect client operation in case of failure of
1042 the connection. Affected file is
1043 irssi/src/silc/core/client_ops.c.
1045 * Do not set sock->protocol to NULL in the function
1046 silc_client_close_connection after executing the protocol's
1047 final callback since the sock might not be valid anymore.
1048 Affected file lib/silcclient/client.c.
1050 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1052 * Do not enable SILC_THREADS if the linking with libpthread
1053 did not happen. Affected file configure.in.pre.
1055 * Added notion to protocol specification that server must
1056 verify the sent authentication payload with CMODE when
1057 setting the channel founder key. Implemented it to the
1058 server. Affected file silcd/command.c.
1060 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Added _EXTRA_DIST SILC distribution variable to the
1063 distributions file. It is used to conditionally add extra
1064 files or directories to the specific distribution. Affected
1065 files ./prepare, Makefile.am.pre and distributions.
1067 Removed the `_' from the start of the distribution names.
1070 * Added README.WIN32 for instructions to compile the Toolkit
1073 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1075 * Fixed a double free in disconnection in the server. Affected
1076 file is silcd/server.c.
1078 * Fixed the lib/silcske/groups.c to work now also with GMP
1079 MP library. The string conversion did not work when using
1080 specific base and the base is indicated in the string as well.
1082 * Created win32/ directory which now includes MSVC++ specific
1083 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1084 It will appear only in the toolkit distribution
1086 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * Changed the key material distribution function in case when
1089 the hash output is too short. The data is now concatenated
1090 a bit differently than it used to. Made the change to the
1091 SKE protocol specification.
1093 * Added better GMP detection to configure.in.pre. A patch
1096 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Fixed a minor bug in SKE that might cause some problem on
1099 some platforms. Affected file lib/silcske/silcske.c.
1101 * Added the cookie checking for initiator in the SKE. It checks
1102 that the responder returns the sent cookie unmodified. The
1103 affected file is lib/silcske/silcske.c. Added new SKE
1104 error type INVALID_COOKIE that can be sent during the
1105 negotiation. Fixed some memory leaks as well.
1107 * Added the "invalid cookie" error message to Irssi SILC client's
1110 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Added `task_max' field to the SilcClientParams to indicate
1113 the maximum tasks the scheduler can handle. If set to zero,
1114 default values are used. Affected file lib/silcclient/silcapi.h.
1116 * Fixed memory leaks in silc_client_close_connection. Affected
1117 file lib/silcclient/client.c.
1119 * Added silc_client_del_client_entry to client library to free
1120 all memory of given client entry. Affected file is
1121 lib/silcclient/idlist.[ch].
1123 * Added new functions silc_client_del_channel and
1124 silc_client_del_server to delete channel and server entries.
1125 Affected file lib/silcclient/[silcapi.h/idlist.c].
1127 * Removed silc_client_del_client_by_id from silcapi.h.
1129 * Fixed the INFO command to return the server's own info
1130 correctly when querying by Server ID. Affected file is
1133 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1135 * Removed the non-blocking settings in WIN32 code in the
1136 silc_sock_[read/write] and added SleepEx instead. Affected
1137 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1138 of input data is now checked with FIONREAD and ioctlsocket.
1140 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Call silc_schedule_task_del_by_context in the
1143 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1144 Affected file lib/silccore/silcprotocol.c.
1146 * Call silc_protocol_cancel for active protocols in the
1147 silc_server_close_connection if the funtion
1148 silc_server_free_sock_user_data has not been called.
1149 Affected file silcd/server.c.
1151 * Generic tasks cannot be deleted using the del_by_fd
1152 task deleting function since generic tasks does not match
1153 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1155 * Added a notion to SILCOPER help file that the SILCOPER works
1156 only on router server, not on normal server.
1158 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1160 * Added for WIN32 support for the new scheduler as well.
1161 Affected file lib/silcutil/win32/silcwin32schedule.c.
1163 * Fixed the SHA1 implementation to work on various platforms.
1165 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1168 API. It is part of the scheduler now. Everything else is
1169 as previously but some functions has changed their names.
1170 Checkout the lib/silcutil/silcschedule.h for the interface.
1171 Updated all applications to use the new interface. Affected
1172 files are lib/silcutil/silcschedule.[ch].
1174 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1176 * Found a bug in the SKE implementation. The HASH value,
1177 specified by the protocol, was not computed correctly. The
1178 public key of the responder was not added to the computation
1179 even though it is mandatory. Affected file lib/silcske/silcske.c.
1180 This unfortunately causes incompatibilities with older
1181 clients and servers.
1183 * Added WIN32 specific network init and uninit functions:
1184 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1185 the Winsock2. Affected file lib/silcutil/silcnet.h and
1186 lib/silcutil/win32/silcwin32net.c.
1188 * Set the socket always to nonblocking mode on WIN32 after
1189 reading data or writing data. Affected file is
1190 lib/silcutil/win32/silcwin32sockconn.c.
1192 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * Fixed various compilation problems under WIN32. Affected
1195 files lib/silcutil/win32/silcwin32thread.c and
1196 lib/silcutil/win32/silcwin32schedule.c.
1198 * Removed all _internal.h #includes from public header
1199 files. Internal headers must never be included from
1202 Removed also the lib/silcske/payload_internal.h file.
1204 * All include files that may be needed (public and some others
1205 included by the public headers) by application developers are
1206 now copied to the ./includes directory. It does not copy any
1207 internal headers. Affected file Makefile.defines.pre and all
1208 Makefile.am's under lib/ and subdirs.
1210 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Do not change the ~/.silc directory's permissions automatically.
1213 Affected file irssi/src/silc/core/clientutil.c.
1215 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Do not cancel the protocol in silc_server_close_connection
1218 it might cause recursion. Now cancelled in the function
1219 silc_server_free_sock_user_data. Affected file silcd/server.c.
1221 * Fixed the silc_server_remove_clients_by_server to regenerate
1222 the channel keys correctly finally. Added also new function
1223 silc_server_remove_clients_channels to actually do it.
1224 Affected file silcd/server.c.
1226 * Fixed the silc_server_new_channel to not crash by giving
1227 wrong router to the new channel. Affected file is
1228 silcd/packet_receive.c.
1230 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1233 which is given as argument to the silc_client_alloc now.
1234 It can be used to configure the client and set various parameters
1235 that affect the function of the client.
1237 * The USERS command in server did not check whether the channel
1238 is private or secret. Affected file silcd/command.c.
1240 * Added new argument to the USERS command in protocol specification.
1241 The USERS command now can take the channel name as argument
1242 as well. Added support for this in client and server and
1243 updated the protocol specs.
1245 * Completed the GETKEY command in client. It can be now used
1246 to fetch also servers public key not only some clients.
1247 Affected files lib/silcclient/command[_reply].c.
1249 * Added silc_client_get_server to return server entry by the
1250 server name. Affected files lib/silcclient/silcapi.h and
1253 * Redefined the IDENTIFY command in protocol specification to be
1254 more generic. It now can be used to query information about
1255 any entity in the SILC Network, including clients, servers and
1256 channels. The query may be based either the entity's name
1257 or the ID. Added support for this in both client and server.
1259 Affected files silcd/command.c and lib/silcclient/command.c
1260 and command_reply.c.
1262 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1263 the _from_client and _from_server functions. Affected file
1266 * Added silc_client_get_channel_by_id_resolve to the file
1267 lib/silcclient/silcapi.h to resolve channel information by
1268 its ID. Added also silc_client_get_channel_by_id that
1269 does not resolve it from the server.
1271 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1273 * Added SilcServerEntry context into the client library
1274 to represent one server. The INFO command now allocates
1275 these to save the resolved server info. For now on the
1276 client library will also keep information about servers,
1277 connected and resolved with INFO.
1279 The INFO command now allocates the SilcServerEntry context
1280 and saves the server info there. The COMMAND_REPLY in
1281 the INFO now returns the parameters to application in
1282 same order as defined in the protocol specification.
1284 The entries are cached in the client->server_cache.
1286 * The INFO command is now issued after received the Client ID
1287 from the server. Affected file lib/silcclient/client.c.
1289 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1290 to the application as the mode changer might be server.
1291 It is guaranteed that NULL is not returned anymore to the
1292 application. Affected file lib/silcclient/client_notify.c.
1294 The ID Type is now also passed to the application so that
1295 it can check whether the returned entry is SilcClientEntry
1298 Added new function silc_client_get_server_by_id to return
1299 the server entry by ID. Affected files are the
1300 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1302 * Do not create the channel in the Irssi SILC Client when issuing
1303 the JOIN command but when received the sucessful JOIN command
1304 reply. Otherwise the channel might get created even though we
1305 could not join it. The Affected file is
1306 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1308 * Fixed a channel joining bug in router. The router must also
1309 check the channel modes, invite and ban lists etc. when serving
1310 the JOIN command sent by normal server. Affected file is
1311 silcd/command.c. The router now resolves the client's
1312 information from the server who sent the JOIN command if it
1313 does not know it, and processes the JOIN command only after
1316 * Changed the SilcCommandCb to take new argument; void *context2.
1317 Affected file lib/silccore/silccommand.h
1319 The second argument in the command callbacks in the server now
1320 includes the SilcServerCommandReplyContext if the command was
1321 called as pending command callback from the command reply.
1322 Otherwise it is NULL. When called as pending the status of the
1323 command reply will be checked and if it was erronous the
1324 error will be sent to the original sender of the command.
1325 This way the client always receives the error messages even
1326 though the server was actually the one who received the error
1327 when it resent the command to router, for example. Affected
1328 files silcd/command[_reply].[ch].
1330 * Fixed sending WHOWAS command's error message to client if
1331 the requested client could not be found. It was missing.
1334 * Changed the CMODE and CUMODE commands reply arguments in the
1335 protocol specification. The Channel ID is now sent in both
1336 of the commands to identify the channel. Implemented this
1337 new feature to the client and server. Affected files
1338 lib/silcclient/command_reply.c and silcd/command.c.
1340 * Made better checks for invite and ban lists in the JOIN
1341 command in server. Affected file silcd/command.c.
1343 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1345 * The server now performs the incoming host IP/DNS lookup
1346 using the silc_socket_host_lookup and thus does not block
1347 the server anymore. Affected file silcd/server.c.
1349 * Completed the multi-thread support for SILC Scheduler in
1350 the lib/silcutil/silcschedule.c.
1352 * Fixed the configure.in.pre to detect the pthread correctly
1355 * Fixed a deadlock in silc_task_queue_wakeup in the file
1356 lib/silcutil/silctask.c.
1358 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1360 * Added new function silc_schedule_wakeup that is used in
1361 multi-threaded environment to wakeup the main thread's
1362 schduler. It needs to be used when a thread adds a new task
1363 or removes a task from task queues. After waking up, the
1364 scheduler will detect the task queue changes. If threads
1365 support is not compiled in this function has no effect.
1366 Implemented the wakeup mechanism to both Unix and WIN32
1367 systems. Affected files are lib/silcutil/silcschedule.[ch],
1368 lib/silcutil/unix/silcunixschedule.c and the
1369 lib/silcutil/win32/silcwin32schedule.c.
1371 * Added new function silc_task_queue_wakeup to wakeup the
1372 scheduler by the specified task queue. Affected file
1373 lib/silcutil/silctask.[ch].
1375 * The silc_socket_host_lookup_start now wakes up the scheduler
1376 after adding the timeout task. Affected file is
1377 lib/silcutil/silcsockconn.c.
1379 * The silc_socket_host_lookup is synchronous now if the threads
1380 support is not compiled in. However, the callback is still
1381 called asyncronously through the scheduler, anyway. Affected
1382 file lib/silcutil/silcsockconn.c.
1384 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1386 * Added new function silc_socket_host_lookup to perform
1387 asynchronous IP and FQDN lookups for the socket connection.
1388 Affected files lib/silcutil/silcsockconn.[ch].
1390 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1393 that may or may not compile the mutex support in.
1395 Changed the silc_mutex_alloc interface. It allocates the
1396 mutex now to the sent pointer and returns TRUE or FALSE.
1398 Affected file lib/silcutil/silcmutex.h.
1400 * Wrote the SILC Task Queue interface to support multi-threads.
1401 Affected file lib/silcutil/silctask.[ch].
1403 * Wrote the SILC Scheduler to support multi-threads. Affected
1404 file lib/silcutil/silcschedule.c.
1406 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1408 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1409 in lib/silcutil/win32/.
1411 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Defined SILC Mutex API and SILC Thread API and implemented
1414 them for Unix. Affected files are
1415 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1416 lib/silcutil/unix/silcunixmutex.c and
1417 lib/silcutil/unix/silcunixthread.c.
1419 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1421 * Fixed the silc_server_remove_clients_by_server's channel
1422 key re-generation. The hash table handling was incorrect
1423 and would not work with many channels. Affected file is
1426 * Fixed some memory leaks around the server code.
1428 * Rewrote the silc_server_get_users_on_channel to support IPv6
1429 based Client ID's. Affected file silcd/server.c.
1431 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1432 specification. However, a separate document must be written
1433 to define the detailed signing procedure and the payload
1434 associated with the flag. Defined the flag to the
1435 lib/silccore/silcchannel.h as well.
1437 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1439 * Changed the dynamic tables to static size tables in the
1440 lib/silccrypt/silchmac.c.
1442 * Removed GCC dependencies from the code. A patch by cras.
1444 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Do not show the error "Error receiving packet bla bla"
1447 in server if it really was not an error (-2 means that reading
1448 is pending). Affected file silcd/server.c.
1450 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Fixed a possible crash in silc_server_remove_clients_by_server
1453 in silcd/server.c. Fixed there also some memory leaks.
1455 * Fixed the silc_idlist_replace_client_id. It could replace
1456 wrong key in the hash table. Affected file silcd/idlist.c.
1458 * Do not check whether there are global users on the channel
1459 if the channel->global_users is FALSE. Affected functions
1460 silc_server_remove_from_one_channel and
1461 silc_server_remove_from_channels in silcd/server.c. Also,
1462 do not check if the removed client is local as we can be
1463 sure that global client was not removed from the channel
1464 and checking for global users is not needed.
1466 * The silc_server_remove_clients_by_server now re-generates
1467 the channel keys correctly for those channels that had
1468 clients removed from them. Affected file silcd/server.c.
1470 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1472 * Found the reason of random crashes in the server. We weren't
1473 ignoring the SIGPIPE signal (which can be sent in write())
1474 and it crashed the server. Affected file silcd/silcd.c.
1476 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1478 * Assure that sock->user_data is not NULL in the function
1479 silc_server_packet_send in silcd/packet_send.c.
1481 * Disconnect the remote connection if it could not be added
1482 to any ID lists in the server. The affected file is
1485 * Check in silc_server_packet_send[_real/dest] that the
1486 socket is not disconnecting and ignore the data if it is.
1487 Affected file silcd/packet_send.c.
1489 * Define inline to __inline on native WIN32 compilation.
1490 Affected file includes/silcwin32.h.
1492 * Added some explicit type casts for inline code since MSVC
1493 require them. Affected files lib/silcutil/silcbuffer.h,
1494 lib/trq/silcdlist.h and lib/trq/silclist.h.
1496 * Print warning in log files from now on if the packet
1497 decryption fails. Affected file silcd/server.c.
1499 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Changed the `say' client operation's interface to accept
1502 new `type' argument to indicate the type of the message sent
1503 by the library. The application may filter the library's
1504 messages according the type. The affected file is the
1505 lib/silcclient/silcapi.h.
1507 * Added two new functions to lib/silcclient/silcapi.h:
1508 silc_client_del_client and silc_client_del_client_by_id.
1509 Affected file lib/silcclient/idlist.c.
1511 * Moved the clientincludes.h from includes/ to silc/ and
1512 serverincludes.h from includes/ to silcd/.
1514 * The modes for the CMODE and CUMODE are now passed as
1515 uint32 for application with COMMAND_REPLY. The affected
1516 file is lib/silcclient/command_reply.c.
1518 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * /WHOIS without arguments shows client's own information.
1521 Affected file lib/silcclient/command.c.
1523 * Changed PING to not accept any arguments. The specs
1524 says that client can ping only the connected server so
1525 requiring an argument is not needed. Affected file is
1526 lib/silcclient/command.c.
1528 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Fixed a fatal bug in private message sending and reception
1531 encryption and decryption when using private message keys.
1532 The implementation was incorrect and did not follow the
1533 specification. It causd that some of the message were
1534 lost since it did not use the sending and receiving keys
1535 as the protocol suggests. This has been fixed and will cause
1536 incompatibilities with older clients when sending private
1537 message encrypted with private message keys. Affected files
1538 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1539 and various other in Irssi SILC Client.
1541 Added `responder' boolean argument to the functions
1542 silc_client_add_private_message_key[_ske] to indicate when
1543 the key is added as responder or initiator of the key
1546 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1548 * Removed the silc_ske_check_version function and created
1549 a SilcSKECheckVersion callback. Added also a function
1550 silc_ske_set_callbacks that is now used to set all SKE
1551 callbacks. The callback functions are not given to
1552 the SKE functions anymore, but this function is used to
1555 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1557 * Added `silc_version' argument to the silc_client_alloc
1558 to define the version of the application for the library.
1559 The library will use the version string to compare it
1560 against the remote host's (usually a server) version
1561 string. Affected file lib/silcclient/silcapi.h
1563 * Added the KE protocol context to Key Agreement context
1564 in client library so that we can abort the SKE if it
1565 is in process when we get timeout. Affected file is
1566 lib/silcclient/client_keyagr.c.
1568 * Do not resolve the client ID forever if it returns in the
1569 first time that such client does not exist. This was done
1570 for example with private message. Affected file is
1571 lib/silcclient/client_prvmsg.c.
1573 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1575 * Do not add regex.h for WIN32. The affected file
1576 includes/silcincludes.h.
1578 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1579 not work yet 100%. It generates the DLL's automatically
1580 when compiling with --with-win32 under cygwin.
1582 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1584 * lib/contrib/regex.c is not compiled on WIN32.
1586 * Added silc_net_get_socket_opt function to the
1587 lib/silcutil/silcnet.h.
1589 * Added includes/silcwin32.h for WIN32 specific includes
1592 * Do not use ptime structure or any of the posix process
1593 functions on WIN32 in lib/silccrypt/silrng.c.
1595 * Added silc_gettimeofday to provide generic function
1596 for struct timeval on all platforms. Added the function
1597 to lib/silcutil/silcutil.h.
1599 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1601 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1602 library as they clearly belong there. As a plus side we
1603 can make the actual socket connection routines platform
1606 Added also new generic function silc_socket_read and
1607 silc_socket_write (that used to be silc_packet_[read/write].
1608 The implementation of these are platform specific.
1610 * Added WIN32 specific routines of silc_socket_[read/write]
1611 to lib/silcutil/win32/silcwin32sockconn.c.
1613 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Added preliminary support for native WIN32 compilation under
1616 cygwin (using the -mno-cygwin option for GCC) to the
1617 ./configure.in.pre. The --with-win32 now prepares the
1618 compilation for native WIN32.
1620 * Rewrote the SILC Scheduler interface in the file
1621 lib/silcutil/silcschedule.h. The scheduler is now context
1622 based and does not have anymore any global static scheduler.
1623 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1624 and created lib/silcutil/win32 directory for WIN32 based
1627 * Added Unix specific network routines to the
1628 lib/silcutil/unix/silcunixnet.c and the old
1629 lib/silcutil/silcnet.c includes now only generic routines.
1631 Added WIN32 specific network routines to the
1632 lib/silcutil/win32/silcwin32net.c.
1634 * Added Unix specific utility functions from the
1635 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1637 * Added WIN32 SILC Scheduler to the file
1638 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1641 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * Do not handle JOIN notify in the server if the target client
1644 is not registered (idata->registered == FALSE). The affected
1645 file is silcd/packet_receive.c.
1647 * Update the nickrec->founder in event_cumode in the Irssi SILC
1648 client. Affected file irssi/src/silc/core/silc-channels.c.
1650 * Fixed the CUMODE_CHANGE notify handling in the server when
1651 server and router are announcing their clients on channels.
1652 Now the mode changes are saved and notified correctly. The
1653 affected file is /silcd/packet_receive.c.
1655 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1656 They really did not replace the cache entry in the ID Cache.
1657 Now they do that. Affected file silcd/idlist.c.
1659 * Fixed the KICK notify handling in the Irssi SILC client to
1660 update the channel records so that the kicked client does not
1661 appear to be on the channel. The affected file is
1662 irssi/src/silc/core/silc-channels.c.
1664 * Always update the conn->current_channel when executing command
1665 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1667 * Fixed the KILL notify handling in Irssi SILC client to remove
1668 the killed client on all channels.
1670 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Fixed the silc_parse_command_line to remove extra spaces
1673 from the start and end of the arguments. Affected file is
1674 lib/silcutil/silcutil.c.
1676 * Cancel and free any active protocol in the function
1677 silc_server_close_connection. Affected file silcd/server.c.
1679 * Cancel and free any active protocol in the function
1680 silc_client_close_connction. Affected file is
1681 lib/silcclient/client.c.
1683 * Do not execute the KILL command for clients that are in
1684 history (ie. they are not in the network). Affected file is
1687 * Fixed KILL notify handling, client does not crash anymore.
1688 Affected file irssi/src/silc/core/silc-channels.c.
1690 * Reduced the default packet buffer size from 2048 to 1024 in
1691 lib/silccore/silcpacket.c.
1693 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1694 counter to the SKE context that is incresed when the SKE library
1695 performs async operation outside the library. If the outside
1696 process frees the SKE context and FREED status will be set
1697 and the library will detect after the sync operation that the
1698 libary is freed. The affected files are
1699 lib/silcske/silcske[_status].[ch].
1701 * Resolve the client entry information in the function
1702 silc_client_channel_message to assure that NULL pointer is not
1703 passed as client entry to the application. */
1705 * Fixed the task timeout calculation to assure that there is
1706 never negative timeouts. The affected file is
1707 lib/silcutil/silcschedule.c.
1709 * Fixed the channel user mode notification sending in server.
1710 It was sent point-to-point to the router (or to server by router)
1711 but it needs to be destined to a channel. The routines now
1712 supports sending the channel user mode notifys to the channels
1713 when announcing clients and channels. Affected files are
1714 silcd/server.c and silcd/packet_receive.c.
1716 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1717 It did not actually replace the old channel entry in the cache.
1718 Affected file lib/silcclient/client_notify.c.
1720 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Fixed a possible crash in silc_packet_send_prepare. It now
1723 assures always that there is enough space in the buffer and
1724 at the tail area of the buffer (for MAC).
1726 Fixed the inbound buffer reallocation in silc_packet_read.
1727 It was old code and did not handle the reallocation correctly.
1730 The affected file is lib/silccore/silcpacket.c.
1732 * Fixed buffer overflow in silc_parse_nickname in the file
1733 lib/silcutil/silcutil.c.
1735 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * make install generates new server keys only if there is not
1740 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1743 Added check that if the NOREPLY is set then we will not send
1744 the away message. This avoids infinite loop of away messages
1745 if both clients are away. The affected file is
1746 lib/silcclient/client_prvmsg.c.
1748 * Fixed client crash if /NICK was given without arguments.
1749 Affected file lib/silcclient/command.c.
1751 * Server does not send the invite list in INVITE command back
1752 to the client if the list was not altered. Added this notion
1753 to the protocol spec as well. Affected file silcd/command.c.
1755 Fixed possible crash in INVITE command by checking the
1756 value of silc_server_get_client_route command.
1758 * Fixed the INVITE notify type handling. The arguments are now
1759 taken in correct order and client does not crash. The affected
1760 file is irssi/src/silc/core/silc-channels.c.
1762 Removed the "Inviting xxx to channel" message from the
1763 client library away and let the application handle it.
1764 Affected file lib/silcclient/command.c. Added that message
1765 to Irssi SILC client's message formats.
1767 * Fixed CMODE command crash in client. It now checks the
1768 amount of arguments correctly and does not crash. The affected
1769 file is lib/silcclient/command.c.
1771 * Do not create new channel automatically in silc_channels_join
1772 but check whether the channel by that name already exists.
1773 Affected file irssi/silc/core/silc-channels.c.
1775 * Do not send the SERVER_SIGNOFF to router if the disconnected
1776 entity was the router. Affected file silcd/server.c.
1778 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1779 SILC client as it was missing from there.
1781 Added the handling of the KICK notify to the Irssi SILC client
1782 as it was missing. Added "you have been kicked" message to
1783 Irssi SILC client's message modules formats.
1785 Added the handing of the KILL notify to the Irssi SILC client
1786 as it was missing. Added the kill message module formats
1789 The affected file is irssi/src/silc/core/silc-channels.c.
1791 * The router did not save the channel mode the server announced.
1792 Affected file silcd/packet_receive.c.
1794 * Fixed a possible crash in INFO command in server. If the
1795 server did not provide the server info it crashed. Affected
1796 file silcd/command.c.
1798 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Fixed the GETKEY command in the server to check also the
1801 global list. Otherwise the GETKEY would not work correctly
1802 in normal SILC server. Affected file silcd/command.c.
1804 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Fixed GETKEY crash, it crashed if the command did not succseed.
1808 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1811 is now real and not just an macro interface to GMP.
1813 Removed the entire GMP from the source tree and imported new
1814 NSS MPI library instead. Reason for removing GMP is that it is
1815 extremely large and compiles extremely slow. The NSS MPI
1816 is only a few files and compiles in less than 10 seconds.
1817 The speed is also about the same as GMP. The MPI is imported
1818 to lib/silcmath/mpi.
1820 If the system has GMP installed we will still use the GMP.
1821 If it is not then the NSS MPI will be compiled.
1823 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Merged a long nickname (127 characters long) crash bugfix from
1826 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1828 * Merged a freed memory reference bugfix from Irssi CVS tree.
1829 Affected file irssi/src/core/commands.c.
1831 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Added the server's public key sving and verification to the
1834 server when performing the SKE. This was missing and the
1835 remote server's (or router's) public key was accepted without
1836 checking whether we have it previously or trust it at all.
1837 Affected file silcd/protocol.c.
1839 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Check in the silc_server_timeout_remote if protocol is active
1842 and make sure that the protocol's final callback is called so
1843 that all memory if freed. Affected file silcd/server.c.
1845 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * silc_server_whois_send_reply crashed the server if the nickname
1848 was 127 characters long. Affected file silcd/command.c.
1850 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Added sanity check to the silc_server_new_client. If the hostname
1853 is provided inside username then check that the provided hostname
1854 really is the same as the resolved one. If the hostname was not
1855 resolved then check it from the public key. Affected file is
1856 silcd/packet_receive.c.
1858 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1859 if the server disconnected us and the connection is not valid
1860 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1862 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1863 the library to the lib/silcutil/silcutil.[ch].
1865 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Close log file after open. Affected file
1868 lib/silcutil/silclog.c.
1870 * Check whether sock == NULL in silc_client_send_packet and return
1871 if it is. Affected file lib/silcclient/silcclient.c.
1873 * Check rec->entry == NULL in the Irssi SILC Client before
1874 sending the channel message. Affecte file is
1875 irssi/src/silc/core/silc-servers.c.
1877 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Merged a splitted window bugfix from Irssi CVS tree. The
1880 affected file is irssi/src/fe-text/textbuffer-view.c.
1882 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1883 It did not print nickname.
1885 * Improved the distributions system a bit.
1887 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1889 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1890 irssi/src/fe-text/gui-window.c.
1892 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1893 to in-active server. The affected file is
1894 irssi/src/silc/core/client_ops.c.
1896 * Resolve the client in USERS command reply if the entry does
1897 not have username resolved. The affected file is
1898 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1899 command to WHOIS command to really resolve stuff. The USERS
1900 is not used any more in any critical section so WHOIS can
1901 be used even though it might be slower than IDENTIFY.
1903 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1906 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Changed the protocol API a bit more consistent in the
1909 lib/silccore/silcprotocol.[ch].
1911 * Changed the following headers to ROBODoc format:
1913 lib/silccore/silcpayload.h
1914 lib/silccore/silcprotocol.h
1915 lib/silccore/silcsockconn.h
1917 All core library headers are now formatted.
1919 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Fixed a bug in Irssi SILC client; do not show that you are
1922 server/router operator if you really are not. Affected file is
1923 irssi/src/silc/core/client_ops.c.
1925 * Renamed silc_command_free_payload to silc_command_payload_free.
1926 Affected file lib/silccore/silccommand.h
1928 * Added silcmath.h to include the prototoypes of various routines
1929 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1932 * Changed the following headers to ROBODoc format:
1934 lib/silccore/silcchannel.h
1935 lib/silccore/silccommand.h
1936 lib/silccore/silcid.h
1937 lib/silccore/silcidcache.h
1938 lib/silccore/silcmode.h
1939 lib/silccore/silcnotify.h
1940 lib/silccore/silcpacket.h
1941 lib/silcmath/silcmath.h
1943 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Added checking to the server code not to start the server if
1946 ciphers and stuff are not configured properly. Affected files
1947 silcd/serverconfig.[h] and silcd/server.c.
1949 * Changed the layout of the header files of the public interfaces
1950 in the SILC libraries. The new layout supports ROBODoc
1951 documentation tool (and some others) so that it is easy to create
1952 a library reference manual. All the other headers and source
1953 code must still follow the CodingStyle document. Also source
1954 code must not include these ROBODoc stuffs, only the headers.
1955 Furthermore, all public interface headers must now be named
1956 by using `silc' prefix, example: silcapi.h, silccipher.h.
1957 Some files were renamed due to this. All the other headers
1958 must not be used as public interfaces. I will update the
1959 CodingStyle document later. Changed following headers, so far:
1961 lib/silcclient/silcapi.h
1962 lib/silccore/silcauth.h
1963 lib/silccore/silcprivate.h
1964 lib/silccrypt/silcdh.h
1966 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1970 * Removed silc_client_packet_send_flush from the client library
1971 as it is not needed. Affected file lib/silcclient/client.[ch].
1973 * Added printing of message of unresolved authentication method
1974 to the Irssi SILC client. Added it to the module formats.
1975 Removed the same message from the client library.
1977 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * Added new distribution feature, DISTLABEL. Every distribution
1980 can define own preprocessor label that can be used in the
1981 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1982 file distributions, acconfig.h.pre and prepare.
1984 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Added Makefile.defines_int to include the actual definitions
1987 for Makefile.defines.in. Tested the new distribution system,
1988 created distributions and tested installation.
1990 * Added AWAY message printing to the Irssi SILC client. Added
1991 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1993 * Added SCONNECT command to call the SILC's CONNECT command.
1994 Cannot use CONNECT directly since Irssi uses that internally.
1995 Affected file irssi/src/silc/core/silc-servers.c.
1997 Added ACTION local command. It is same as ME command but takes
1998 the channel as mandatory argument.
2000 Rewrote some of the Irssi's help files to suite for SILC
2003 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Added Makefile.defines[.in] that should for now on be included
2006 in all Makefile.am file in the source tree. That file includes
2007 all common compilation definitions for SILC source tree.
2009 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Minor changes to the ./prepare script to change the package
2012 name according the distribution name to the configure.in.
2014 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Created new distribution system. Added file `distributions'
2017 that defines all the distributions that can be created out of
2018 the SILC source tree. The ./prepare script now reads that
2019 file to determine how to prepare the distributions. The
2020 first argument to the ./prepare is the name of the distribution
2021 and second is the version of the distribution. If given
2022 without arguments it creates the default (toolkit) distribution
2023 with the default version (defined in ./prepare).
2025 All Makefile.am files that are subject to the distributions
2026 are now named as Makefile.am.pre. These are ./Makefile.am
2027 and lib/Makefile.am. Others may be changed later.
2029 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Added invite list, ban list, some key management and connection
2032 error message printing to module formats in the Irssi SILC client.
2034 * Added new silc_client_set_away_message to set the away message
2035 that is back to the person who sent private message. The
2036 affected file lib/silcclient/silcapi.h and the
2037 lib/silcclient/client_prvmsg.c.
2039 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Fixed the private message sending in the Irssi SILC client,
2042 added local command KEY to the Irssi SILC client.
2044 Added key management and key agreement message formats to the
2045 irssi/src/fe-common/silc/module-formats.[ch].
2047 Added USERS (alias WHO) printing, server/router operator
2048 indication and LIST command printing to the module formats.
2050 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Fixed channel joining notify handling, cumode notify handling
2053 from Irssi SILC client.
2055 * Added SILC specific module-formats to the Irssi SILC client so
2056 that SILC specific message hilighting, colors etc is possible.
2057 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2059 Added channel mode, channel user mode, actions, notices,
2060 whois and whowas printing to the the module-formats.c.
2062 * Fixed a bug in channel deletion in the server. The channel
2063 is not left to the cache even if the channel founder auth mode
2064 is set when there are no users anymore on the channel. Affected
2065 file silcd/server.c.
2067 * The silc_net_localhost now resolves the entire hostname including
2068 the domain name. Affected file lib/silcutil/silcnet.c.
2070 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2072 * Changed the ask_passphrase client operation to be ascynchronous.
2073 It has now a completion callback and a context that the
2074 application must call after it has got the passphrase from
2075 the user. Affected files lib/silcclient/silcapi.h,
2076 lib/silcclient/protocol.c, lib/silcclient/command.c and
2079 Added SilcAskPassphrase callback that the application calls
2080 to deliver the passphrase to the library.
2082 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2083 The public key verification and especially a certificate
2084 verification is asynchronous procedure.
2086 Added new SILC_SKE_STATUS_PENDING status to indicate the
2087 request is pending and a callback will be called to finalize
2090 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2091 indicate that remote end did not send its public key (or
2092 certificate), even though we require it. Added check for this
2093 condition in the SKE. This was a security bug, now fixed.
2095 Defined new SilcSKEVerifyCbCompletion callback that is called
2096 when the verification process is completed.
2098 The affected files lib/silcske/silcske_status.h and
2099 lib/silcske/silcske.[ch].
2101 * Changed the verify_public_key client operation to be async
2102 as well. Defined SilcVerifyPublicKey callback that is used to
2103 indicate the success of the public key verification process.
2105 Changed the server and client to use the new async client
2108 * Changed the Irssi SILC client's internal scheduler to be called
2109 twice as many times as it used to be. As a result the client
2110 should be a bit faster now. Affected file is
2111 irssi/src/silc/core/silc-core.c.
2113 * Added support to Irssi SILC client of asynchronous public key
2114 verification and passphrase inquiry. Affected file is
2115 irssi/src/silc/core/silc-core.c.
2117 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Do not say "You have left channel %s" in client library.
2120 Moved it to the application. Affected files are
2121 lib/silcclient/command.c and silc/client_ops.c.
2123 * Fixed silc_client_get_clients. Command context was not
2124 duplicated and was freed memory in the callback. Affected
2125 file lib/silcclient/idlist.c.
2127 * Do not say "you are now talking..." on JOIN command in the
2128 client library. The appliation must handle it.
2130 * Do not say ".. changed topic to" in command reply in the
2131 client libary. The application must handle it.
2133 * Fixed TOPIC command sending in the client library.
2135 * Fixed a memory leak in silc_client_command_free in the file
2136 lib/silcclient/command.c.
2138 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2140 * Imported a modified version of Irssi client to the source tree.
2141 The Irssi will be used to create a new client called
2142 Irssi SILC. Imported to irssi/.
2144 Added silc_core_init_finish function to the Irssi. Affected
2145 file irssi/configure.in.
2147 A lot changes in the Makefile.ams around the irssi tree.
2149 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Do not rehash if the new size is same as the old size of the
2152 hash table, in the silc_hash_table_rehash*. The affected file
2153 lib/silcutil/silchashtable.c.
2155 * Replaced hash_table_del_by_context calls from the server
2156 (when channel->user_list and client->channels) to the
2157 hash_table_del as it is sufficient and faster.
2159 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2161 * Added silc_hash_table_list, silc_hash_table_get and the
2162 SilcHashTableList structure to provide an alternative way to
2163 traverse the hash table. The affected files are
2164 lib/silcutil/silchashtable.[ch].
2166 * Changed the server's idlist routines to use the hash table
2167 routines to optimize the code.
2169 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Replaced the client entry's `channel' list and channel entry's
2172 `user_list' list to hash tables for optimized lookup. Changed
2173 the code to use the hash table interface around the code.
2174 Affected file lib/silcd/idlist.[ch].
2176 * Added `auto_rehash' boolean argument to the function
2177 silc_hash_table_alloc to indicate whether the hash table should
2178 auto-rehash when it thinks is appropriate time. It will
2179 increase the hash table size if the there is twice as much
2180 entries in the table than the size of the table, and will
2181 decrease the size if there are twice as less entries than
2182 the size of the table.
2184 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2188 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * silc_idcache_purge_by_context deletes the entry now by context
2191 as it is supposed to do. Affected file lib/silccore/idcache.c.
2193 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2194 client is not anymore valid (WHOWAS givens the info) and not
2195 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2197 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Removed the `data' and `data_len' arguments from the ID Cache
2200 interfaces and added `name' argument. ID Cache does not handle
2201 anymore the binary data only a names associated with given ID.
2203 * When hashing a Client ID with silc_hash_id the entire ID is
2204 not hashed anymore, instead only the hash of the Client ID is
2205 hashed. This way we can access the Client ID from the cache
2206 with Client ID but with the hash of the ID (which is a hash of
2207 the nickname) as well without any difference in performance.
2209 Added also silc_idcache_find_by_id_one_ext to do one on one
2210 searching when we have the actual ID. Added also function
2211 silc_hash_client_id_compare. The affected files are
2212 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2214 * When hashing the name associated with a ID it is always done
2215 in lowercase. This way we can access the cache without worrying
2216 about case-sensitivity, even though, for example nicknames are
2219 * Fixed a bug in server with channel message sending. It put
2220 wrong ID type as destination ID. The affected file
2221 silcd/packet_send.c.
2223 * silc_idcache_del_by_context now deletes from all hash tables
2224 by context. Affected file lib/silccore/idcache.c.
2226 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Changed the client library to use the new ID Cache interface.
2229 Changes around the source tree.
2231 * Added silc_hash_table_rehash_ext to rehash with specific
2232 hash function. Affected file lib/silcutil/silchashtable.[ch].
2234 * Added silc_hash_string_compare to compare two strings in the
2235 hash table. Affected file lib/silcutil/silcutil.[ch].
2237 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Added new function silc_idcache_del_by_context into the
2240 lib/silccore/idcache.[ch].
2242 * Changed the server's ID list routines to use the new ID Cache
2243 interface. Changes around the source tree.
2245 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Added silc_hash_table_del[_by_context]_ext functions in to the
2248 lib/silcutil/silchashtable.[ch].
2250 Removed silc_hash_table_find_all* routines and added new
2251 silc_hash_table_find_foreach to replace them.
2253 Added silc_hash_table_replace_ext function as extended
2254 replacing function. Separated the simple hash table interface
2255 from the extended hash table interface in the file
2256 lib/silcutil/silchashtable.h.
2258 * Fixed minor bugs and changed it to use some of the new
2259 hash table functions in lib/silccore/idcache.c
2261 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2263 * Added new function silc_hash_table_find_all to return all keys
2264 in the hash table by the specified key. As the hash table is
2265 collision resistant it also makes it possible to have several
2266 duplicate keys in the hash table. This function may be used to
2267 find all of the keys from the hash.
2269 Added user_context arguments to the SilcHashFunction,
2270 SilcHashCompare and SilcHashDestructor to deliver user specified
2273 Added new fuctions silc_hash_table_find[_all]_ext to do
2274 extended lookup with specified hash and compare functions and
2275 specified user contexts.
2277 Added new function silc_hash_table_add_ext to add the key
2278 with specified hash function and user context.
2280 Added new function silc_hash_table_foreach to traverse all
2281 entrys in the hash table. Added SilcHashForeach callback
2284 Added new function silc_hash_table_del_by_context to delete
2285 the entry only if the context associated with the key matches.
2287 Affected files are lib/silcutil/silchashtable.[ch].
2289 * Removed silc_hash_[server/client/channel]_id and added just
2290 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2291 silc_hash_id_compare to compare two ID's using as the hash table
2292 comparison function. Added also silc_hash_data to hash
2293 binary data and silc_hash_data_compare to compare it.
2295 * Removed silc_idlist_find_client_by_hash as it is not needed
2296 anymore. Affected file silcd/idlist.[ch].
2298 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2299 to use internally the SilcHashTable. The new ID Cache is a lot
2300 faster than the old one. Some of the ID Cache interface was also
2301 rewritten and obsolete and stupid functions were removed.
2303 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Added entry_count field to the SilcHashTable to keep the number
2306 of the entries in the table. Implemented the function
2307 silc_hash_table_rehash. Added new function
2308 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2310 Fixed a minor bug in silc_hash_table_free.
2312 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2313 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2314 into the lib/silcutil/silcutil.[ch].
2316 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Implemented a collision resistant hash table into the
2319 lib/silcutil/silchashtable[ch]. See the header and the source
2320 for the SilcHashTable API.
2322 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Merged dotconf version 1.0.2 into lib/dotconf.
2326 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Do not compile anything in lib/silcsim/* if the SIM support
2329 is not enabled. The tree should now compile without problems
2332 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2334 * Compiled the SILC under cygwin. Compiled and tested briefly
2335 without problems. More tests needed. The SIMs didn't compile
2338 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2340 * Fixed possible crash in silc_get_username in the
2341 lib/silcutil/silcutil.c.
2343 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2345 * Fixed a va_arg in silc/client_ops.c.
2347 * Oops, RC5 routines were named AES and caused some problems
2348 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2350 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Added new SilcIDIP structure into the lib/silccore/id.h and
2353 replaced the old `ip' fields from all SILC ID's to that type.
2354 This is a step towards IPv6 support.
2356 The silc_id_get_len takes now the ID as an extra argument.
2357 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2358 both IPv4 and IPv6 based ID's.
2360 The affected files are lib/silccore/id.[ch] and other files
2361 around the tree using these routines.
2363 * Removed the ID length arguments in server from various
2364 silc_server_send_notify_* routines -> they are not needed
2367 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2369 * Fixed memory leak in silc_encode_pem_file in the file
2370 lib/silcutil/silcutil.c.
2372 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Check minor version as well in the SKE. Affected files are
2375 silcd/protocol.c and lib/silcclient/protocol.c.
2377 * Added --identifier option to the server so that an identifier
2378 can be when creating the public key for the server. Affected
2379 file is silcd/silcd.c.
2381 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2382 lib/silccrypt/silcpkcs.c.
2384 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2386 * Register default ciphers and stuff when using -C option with
2387 the server. Affected file sildc/silcd.c.
2389 * Put back the servers public key filename format, it is better
2390 than the new one. For now, the client keys are saved with the
2391 new filename format. The affected file silc/client_ops.c.
2393 * Implemented the Cipher API for the rest of the ciphers that
2394 did not implement it or implemented it the wrong way.
2396 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Register default ciphers and stuff when using the -S option
2399 in the client. Affected file silc/silc.c. Same also when
2400 creating new key pair with -C option.
2402 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2404 * Fixed the silc_verify_public_key client operation function to
2405 save the public keys differently. The fingerprint is now
2406 used as filename and not the hostname. This way also the
2407 client keys are saved uniquely and not with hostnames. The
2408 affected file is silc/client_ops.c.
2410 * Trimmed the silc_hash_fingerprint function to remove extra
2411 whitespaces from the end of the fingerprint. The affected
2412 file is lib/silccrypt/silchash.c.
2416 * Added silc_cipher_register_default function to register all
2417 default ciphers. It can be used when configuration files
2418 does not exist and the application does not want any specific
2419 ciphers in any specific order.
2421 The SilcDList is now used as silc_cipher_list dynamically
2422 allocated cipher list. Removed the static list all together
2423 and now all ciphers must be allocated to the dynamic list.
2424 The silc_cipher_alloc routine was changed to check only the
2427 All silc_cipher_* routines that used to return int returns
2430 The affected files lib/silccrypt/silccrypt.[ch].
2432 * The same thing was done to silc_hash_* as for silc_cipher_*
2433 routines. Affected files lib/silccrypt/silchash.[ch].
2435 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2436 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2437 Added also silc_pkcs_[un]register[_default] functions.
2438 Removed the data_context from the PKCS API.
2440 * Added silc_hmac_register_default function to register default
2441 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2442 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2443 to unregister all hmacs at once.
2445 * Register the default ciphers, hash functions, PKCSs and HMACs
2446 if client's configuration file does not exist. The affected
2449 * The client did not load the hash functions from the SIM
2450 modules at all. Added support for this. Affected file is
2451 silc/clientconfig.c.
2453 * When decoding public key with silc_pkcs_public_key_decode, check
2454 the supported algorithm only if PKCS are registered. Affected
2455 file lib/silccrypt/silcpkcs.c. The same was done with the
2456 silc_pkcs_private_key_decode.
2458 * Fixed the SILC List routines to keep the list always in order.
2459 It used to change the list's order when traversing the list but
2460 not it preserves the order. Affected file lib/trq/silclist.h.
2462 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2464 * Added the client library to use the SilcSocketConnection's
2465 reference counter (by silc_socket_dup) to prevent the bug that
2466 the socket object may be freed underneath async operation.
2468 * The name resolv library checking fixes in the configure.in.pre.
2471 * Created new version of the protocol drafts for future
2472 development. The -03 drafts are the ones that will be changed
2473 in the trunk now and the -02 will remain as they are.
2475 * Send list of CUMODE notifys to the router when announcing
2476 the channel users to the router. Affected file silcd/server.c.
2477 If the router receiving channel founder CUMODE for a channel
2478 that already has channel founder it will send CUMODE notify
2479 to the sender to remove the channel founder rights from the
2480 announced client. Affected file silcd/packet_receive.c.
2482 * The CUMODE notify may now use Server ID as well as the entity
2483 who changes the mode. Updated protocool specs.
2485 * Updated INSTALL and README files.
2487 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2489 * New web pages in the http://silc.pspt.fi. The pages was
2494 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Implemented the [DenyConnectin] config section in the server.
2497 Added silc_server_config_denied_conn to check whether incoming
2498 connection is denied. Affected file silcd/serverconfig.[ch].
2500 * Do not check the ports when checking the incoming configuration
2501 data if the port is 0, meaning any. Affected file is
2502 silcd/serverconfig.c.
2504 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Fixed buffer overflow in silc_string_compare in the file
2507 lib/silcutil/silcutil.c.
2509 * Fixed double free in silc_server_command_leave in the file
2512 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Fixed the version checking in the server. Affected file is
2517 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Fixed the configuration data fetching when accepting new
2520 connections in the server. Affected file silcd/server.c.
2522 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Added `sender_entry' argument to the function
2525 silc_server_packet_relay_to_channel so that we can check
2526 whether some destination actually belongs to the same route
2527 the sender belongs (ie, we must not resend the packet to the
2528 sender). Affected file silcd/packet_send.[ch].
2530 * Added `servername' field to the SilcClientEntry in the server
2531 to hold the name of the server where client is from. Affected
2532 file is silcd/idlist.h.
2534 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Moved the channel message encrypting in the router betwen
2537 router connections from silc_server_channel_message to the
2538 silc_server_packet_relay_to_channel since we want to check
2539 whether we have anybody channel before encrypting anything.
2540 Affected files silcd/packet_[receive/send].c.
2542 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2544 * Fixed the [AdminConnection] server config section to support
2545 multiple entries. Affected file silcd/serverconfig.c.
2547 * Added support into the server to check the validity of the
2548 incoming connection before executing any KE or authentication
2551 * The connection configuration is now saved to the KE and
2552 connection auth protocol contexts and not fetched anymore in
2553 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2555 * The local hosts listenning address and port is also resolved
2556 now when starting the server. We want to have the socket object
2557 to include the real address and port for the listener. Added
2558 new function silc_net_check_local_by_sock into the files
2559 lib/silcutil/silcnet.[ch].
2561 * Fixed a broadcast bug in server -> do not broadcast if we
2564 * Fixed a routing bug. Do not route broadcast packets ever.
2565 Broadcast packets must be processed always and not routed since
2566 they may be destined to some other host than yourself and thus
2567 would get routed without no good reason. Affected file is
2570 * Added function silc_server_config_is_primary_route to check
2571 whether primary router connection has been configured (a router
2572 configuration that we are initiating). If there is not, we
2573 will assume that there is only two routers in the SILC network
2574 and we will use the incoming router connection as our primary
2575 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2577 * Changed the order of the broadcasting. Broadcast _after_ the
2578 packet has been processed not before. Affected file is
2581 * Fixed a [ClientConnection] parsing bug. The port was never
2582 parsed correctly thus resulting to port 0. Affected file
2583 silcd/serverconfig.c.
2585 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2586 argument and did not set the broadcast packet flag. Affected
2587 file silcd/packet_send.c. Fixed same bug in the function
2588 silc_server_send_notify as well.
2590 * If we receive NEW_ID packet for our own ID in the server, ignore
2593 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2597 * Removed the nickname from the Private Message Payload.
2598 Updated the code and the protocol specs.
2600 * Updated protocol specs for submitting to the IETF.
2602 * Tweaked the Random Number Generator a bit. Affected file
2603 lib/silccrypt/silcrng.c. Exported a new function
2604 silc_rng_[global]_add_noise which can be used to add more
2607 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2609 * Do not parse packets with different timeout when protocol
2610 is active -> may cause problem with rekey. Affected file
2613 * When server receives signoff notify it must not create
2614 new channel key if the client is on any channels since the
2615 sender of the signoff notify will create it.
2617 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Added printing of error messages during SKE protocol from the
2620 failure packet sent by server during SKE. Affected file
2623 * Removed the client's failure_callback handling with timeout
2624 and handle it immediately when received.
2626 * The SKE library returned wrong type in SUCCESS and FAILURE
2627 packets. They must be 32 bit MSB not 16 bit MSB.
2629 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Ok, rewrote the logic of the re-key and now it seems to work.
2632 I tested it on high traffic with frequent re-keys without
2633 problems. Added hmac_receive (and renamed hmac to hmac_send)
2634 in SilcClientConnection in lib/silcclient/client.h and
2635 in SilcIDListData in silcd/idlist.h. Also, removed the
2636 SilcPacketParserContext's cipher and hmac fields as they are
2637 not needed anymore and actually caused some problems when
2638 the ciphers and hmac's changed underneath the packet parser.
2640 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2642 * If re-key protocol is active then process the incoming packets
2643 synchronously since we must assure that icoming packets encrypted
2644 with the old key is processed before the new keys is set to
2645 use. This is true other packets than for REKEY packets.
2646 Affected file silcd/server.c. The same was done to client library
2647 as well, affected file lib/silcclient/client.c.
2649 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Fixed bug in client and server to accept the force send if
2652 the packet is send from silc_[server/client]_packet_process
2653 function. Otherwise the packets are never delivered, oops.
2655 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2657 * Disable force sending of packets when REKEY protocol is active.
2658 We must assure that no packet is sent directly when rekey is
2659 performed. All packets must be sent through packet queue.
2660 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2661 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2662 function is silc_[server/client]_packet_send_real to check
2665 * Replaced the SIM paths from example config files to
2666 /usr/local/modules. Also, make install creates now
2667 /usr/local/silc/logs directory to hold all the SILC server
2670 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Made the configure.in.pre work on Solaris. Patch by salo.

2681 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2683 * When MAC computation fails the silc_packet_decrypt returned 0
2684 even though it was supposed to return -1. Fixed this. The
2685 affected file is lib/silccore/silcpacket.c.
2687 * Do not replace the config files in /etc/silc (in make install)
2688 if they already exist. Affected file ./Makefile.am.
2690 * Do not send re-key packets immediately but through packet queue.
2691 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2693 * Changed silc_net_check_host_by_sock to return FALSE if the
2694 IP/DNS could not be resolved. Though, it returns the IP address
2695 now even if it could not resolve it (but returns also FALSE).
2696 Affected file lib/silcutil/silcnet.[ch].
2698 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Added silc_pkcs_decode_identifier to decode the public key's
2701 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2702 Added also silc_pkcs_free_identifier. Added also new context
2703 SilcPublicKeyIdentifier.
2705 * Added -S option to the silc client. It is used to dump the
2706 contents of the specified public key file.
2708 * Changed the PKCS api to return the public key length when
2709 setting the public key.
2711 * Fixed a fatal bug in the public and private key file loading.
2712 Affected file lib/silccrypt/silcpkcs.c.
2714 * Execute the packet parsing for client with zero (0) timeout
2715 if the protocol is active. Affected file silcd/server.c.
2717 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Made the key generation options to the silcd program. Added
2720 -C option, equivalent to client's option.
2722 * Added new [ServerKeys] config section to the server. It
2723 configures the server's public and private key.
2725 * Defined generic Public Key Payload into the protocol
2726 specification to send specific type of public keys and
2729 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2730 public key or certificate.
2732 * Implemented the GETKEY command to the server and to the
2733 client library and on user interface.
2735 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2737 * Made preliminary `make install' work.
2739 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Added SilcServerRekey context into silcd/idlist.h.
2743 * Added the PFS support as defined in the specification to the
2744 SKE protocol. Affected files lib/silcske/*.c.
2746 * Added `ske_group' field to the SilcServerRekey context to hold
2747 the number of the SKE group that is used with PFS in re-key.
2748 Affected file silcd/idlist.h.
2750 * Added PFS re-key support to the server. Affected file is
2753 * Added silc_protocol_cancel to cancel execution of the next
2754 state of the protocol. Affected file is
2755 lib/silccore/silcprotocol.[ch].
2757 * Added the re-key support with and without PFS to the client
2758 library. Re-key is performed once in an hour, by default.
2760 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2761 Added silc_client_rekey_callback and silc_client_rekey_final.
2762 Affected files are lib/silcclient/protocol.[ch] and
2763 lib/silcclient/client.[ch].
2765 * Removed the `hmac_key' and `hmac_key_len' fields from the
2766 SilcClientConnection structure; not needed. Affected file is
2767 lib/silcclient/client.h.
2771 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2773 * Do not ask whether user wants to use the negotiated private key
2774 for private messages, just use it. Affected file is
2775 silc/local_command.c.
2777 * Added `send_enc_key' and `enc_key_len' fields to the
2778 SilcIDListData structure since they are needed in the re-key
2779 phase. Affected file is silcd/idlist.[ch].
2781 * Implemented the simple re-key protocol into the server.
2782 Affected files silcd/server.c and silcd/protocol.[ch]. The
2783 re-key will be performed once in an hour, by default.
2785 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2786 Added silc_server_rekey, silc_server_rekey_callback and
2787 silc_server_rekey_final.
2789 * Removed Tunneled flag from the protocol. Updated the code
2790 and the specifications.
2792 * Adde `pfs' field to the SilcIDListData to indicate whether
2793 the PFS is to be performed in the re-key. Affected file is
2796 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2799 int64 of at least the xintXX size. If void * is less that 4
2800 bytes uint32 * will be used. Defined bool as boolean.
2802 * Changed _ALL_ unsigned long and unsigned int to uint32,
2803 unsgined short to uint16 in the source tree.
2805 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2806 not handle clients that has entry->data.registered == FALSE.
2807 They are not in the network anymore. Affected file is
2810 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Implemented the sending of the SERVER_SIGNOFF notify in the
2813 server. Affected file is silcd/server.c.
2815 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2816 Added also silc_notify_payload_encode_args into the
2817 lib/silccore/silcnotify.[ch].
2819 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2820 Affected file silcd/packet_receive.c.
2822 * Implemented the SERVER_SIGNOFF notify handling in the client
2823 library. Affected file lib/silcclient/client_notify.c. Also,
2824 implemnted the printing of the SERVER_SIGNOFF info to the
2825 application. Affected file silc/client_ops.c.
2827 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2828 if the deleting was successful. Affected file silcd/idlist.[ch].
2830 * Added support for public key authentication in the connection
2831 authentication protocol in the client library. Affected file
2832 lib/silcclient/protocol.c.
2834 * Changed the server's silc_idlist_get_clients_by_* interface
2835 to support already allocated array so that new entries may be
2836 added to pre-allocated array. Affected file silcd/idlist.[ch].
2837 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2838 and command replies.
2840 * All command reply functions in the server now calls the
2841 pending command callback even if error occured. This way the
2842 error will be delivered to the client as well. Affected files
2843 silcd/command.c and silcd/command_reply.c.
2845 * Fixed INFO command to return local server's info if no server
2846 was provided. Affected file lib/silcclient/command.c.
2848 * Removed RESTART command for good. Updated the code and the
2851 * Rewrote parts of the task system. It is a bit simpler now.
2852 Removed unsued task priorities. The affected files are
2853 lib/silcutil/silctask.[ch].
2855 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2857 * Moved the USERS printing from the library to the application.
2858 Affected files lib/silcclient/command.c and silc/client_ops.c.
2860 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2864 * Added channel key re-key support. The re-key is perfomed
2865 only by the router and is done once in an hour. Added `rekey'
2866 field to the SilcChannelEntry in the server. Affected files
2867 silcd/server.c and silcd/idlist.h.
2869 * Added silc_task_unregister_by_context into the file
2870 lib/silcutil/silctask.[ch].
2872 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Added SILC_UMODE_GONE mode to indicate when the client is not
2875 present in the SILC network. Added also support to the local
2876 command AWAY that will set this mode. Added support of showing
2877 "xxx is gone" in WHOIS command. The USERS command shows the
2878 gone status as well.
2880 * Fixed setting server and router operator privileges in the
2881 server's UMODE command. Affected file silcd/command.c.
2883 * Merged the SKE KE1 and KE2 payloads into one payload. The
2884 new KE payload is equivalent to the old KE2 payload.
2886 Cleaned up the SKE Start Payload parsing. It now uses the
2887 simple buffer unformatting to do the parsing. A lot faster
2890 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2891 to the SKE that is used to indicate whether both of the SKE
2892 parties should perform authentication. By default only the
2893 responder performs authentication. By setting this flag also
2894 the initiator must do authentication. By default it is unset
2895 since in normal SKE case, client to server connection, only
2896 the responder should do authentication. When doing SKE between
2897 two clients both should perform authentication. Updated the
2898 code and the protocol specs.
2900 * A little fix to IDENTIFY command in the server. Search the
2901 client first by hash not nickname. Affected file is
2904 * Fixed the silc_client_close_connection to support closing
2905 the client to client connections wihtout deleting too much
2906 data. Affected file lib/silcclient/client.c.
2908 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2909 are received if protocol used to be active but is not anymore
2910 the application would crash due to NULL pointer dereference.
2911 Affected files silcd/server.c and lib/silcclient/client.c.
2913 * Added `hash' field to the SilcClientConnection to include
2914 the hash function negotiated in the SKE protocol.
2916 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2917 to set the channel founder authentication data. A client can
2918 claim the founder rights later by providing the authentication
2919 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2920 This way the channel founder can regain the channel founder
2921 privileges even it is left the channel. This works only on
2922 local server and the client must be connected to the same
2923 server to be able to regain the founder rights. Updated the
2924 protocol specs accordingly.
2926 Added support to the CMODE command in the client to set the
2927 founder auth data. Read the README to see how to set it.
2929 Added support to the CUMODE command to claim the founder
2930 rights. Read the README to see how to do it.
2932 Added support for the founder authentication to the Channel
2933 Entry in the server. Affected file silcd/idlist.h.
2935 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2936 server's CMODE command. Affected file silcd/command.c.
2938 * Added the following new functions into lib/silccore/silcauth.[ch]:
2939 silc_auth_get_method and silc_auth_get_data.
2941 * The server now saves the remote hosts public key to the
2942 SilcIDListData pointer. Affected file silcd/protocol.c.
2944 * The normal server now does not remove the channel entry from
2945 the cache if the founder authentication data is set. It used
2946 to remove it if the founder was the last one on the channel on
2947 the server and left the channel. The auth data is saved and
2948 if the channel is re-joined later the old entry is used with
2949 the old auth data. Affected files silcd/command_reply.c and
2952 * Removed the `pkcs' field from the SilcIDListData structure
2953 in the server; it is not used. Affected file silcd/idlist.h.
2955 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Fixed packet processing on slow links. Partial packets were
2958 never re-processed because the incoming data buffer was cleared
2959 by the application. Application must not directly clear the
2960 sock->inbuf, the packet processing routines handle it. Fixed
2961 this in client library and in server.
2963 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2965 * Fixed the WHOIS and IDENTIFY send reply function to really
2966 check whether to send list or just one entry. Affected file
2969 * Cleaned up the LEAVE command's channel key distribution. The
2970 affected file silcd/command.c.
2972 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2973 can enforce the channel mode as well. In that case the ID
2974 includes the ID of the server. The code now enforces the
2975 mode change if the router have different mode than the server.
2977 * The notify client operation with CMODE_CHANGE notify can now
2978 return NULL client_entry pointer if the CMODE was not changed
2979 by client. Application must check for this.
2981 * Added <Server ID> argument to INFO command to support server
2982 info fetching by Server ID.
2984 * Added silc_server_announce_get_channel_users to get assembled
2985 packets of channel users of the specified channel. Affected
2986 file silcd/server.[ch].
2988 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2989 was freed underneath the ID Cache.
2991 * Re-announce clients when the server received CHANNEL_CHANGE
2992 notify from the router. Affected file silcd/packet_send.c.
2994 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2997 crashed since it did not handle the fact that there is no cipher
2998 called "3" and didn't check the error condition. Now fixed.
3000 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3001 flag. It can be used to send message requests.
3003 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3005 * Implemented the RESTART command in the client.
3007 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3008 notice type messages. Added notice printing to the user
3011 * The channel keys are not re-generated if the channel's mode
3012 is PRIVKEY, ie private key on the channel exists. Affected
3013 files silcd/server.c and silcd/command.c.
3015 * Fixed a little bug in channel message delivery when channel
3016 private keys are set in the server. Affected file is
3017 silcd/packet_send.c.
3019 * Changed the setting on channel->on_channel = TRUE from the
3020 silc_client_save_channel_key to the JOIN command reply. The
3021 key payload is not received if the private channel key is set.
3022 Affected file lib/silcclient/command_reply.c and the
3023 lib/silcclient/client_channel.c.
3025 * When the CMODE_CHANGE notify is sent and the channel private
3026 key mode is removed the channel key must be re-generated in
3027 other cells as well. Added this support for the router in the
3028 silcd/packet_receive.c.
3030 * Added new local command NOTICE to send notice message on
3031 channel. Affected file silc/local_command.[ch].
3033 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added new local command ME to the client. It is used to send
3036 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3037 some action. Affected file silc/local_command.[ch].
3039 * Changed channel_message and private_message client operations
3040 to deliver the message flags to the application. Added also
3041 the `flags' arguments to the silc_client_send_channel_message
3042 and silc_client_send_private_message functions. Affected file
3045 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3047 * Redefined the Private Message Payload to support private message
3048 keys and to support the new private message flags. Updated
3049 the protocol specs. Flags makes it possible to have for example
3050 CTCP style messages.
3052 * Added new type SilcPrivateMessagePayload and defined an API
3053 for it in the lib/silcclient/silcprivate.[ch].
3055 * Tested private message private keys successfully. Tested the
3056 private message key set, unset and list commands with the new
3059 * Redefined the Channel Message Payload to include the channel
3060 message flags (equal with private message flags) to support
3061 for example CTCP style messages.
3063 * Defined some of the message (for channel and private message)
3064 flags. Updated the protocol specs and added the flags to the
3065 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3067 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3069 * Added SilcKeyAgreementStatus type to the key agreement routines
3070 to indicate the current status and error if one occured.
3071 The status types are defined in the lib/silcclient/silcapi.h.
3073 * Added new local command KEY that is used to set and unset private
3074 keys for channels, set and unset private keys for private messages
3075 with remote clients and to send key agreement requests and
3076 negotiate the key agreement protocol with remote client. The
3077 key agreement is supported only to negotiate private message keys,
3078 it currently cannot be used to negotiate private keys for channels,
3079 as it is not convenient for that purpose.
3081 * Fixed a minor pending callback setting bug in the function
3082 silc_client_get_client_by_id_resolve, now the function works.
3083 Affected file lib/silcclient/idlist.c.
3085 * Added function silc_net_get_local_port to get local bound
3086 port by socket. Added to lib/silcutil/silcnet.[ch].
3088 * Added `sockets' and `sockets_count' fields to the SilcClient
3089 object. They hold the sockets of the listenning sockets in
3090 the client. Listenning sockets may be for example the key
3091 agreement server. Affected file lib/silcclient/client.[ch].
3092 Added functions the silc_client_add_socket and the
3093 silc_client_del_socket. They are exported to the application
3096 * Added ~./silc/clientkeys to support other client's public keys.
3098 * Renamed verify_server_key client operation to verify_public_key
3099 and added one argument to indicate the type of the connection
3100 (server, client etc.).
3102 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3104 * Added silc_server_connection_auth_request to handle the
3105 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3106 silcd/packet_receive.[ch].
3108 * Added silc_server_send_connection_auth_request into the
3109 silcd/packet_send.c to send the connection auth request packet.
3111 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3114 * Fixed the public key authentication in responder side in the
3115 server. The `auth_data' pointer includes the SilcPublicKey
3116 not the path to the public key. Affected file silcd/protocol.c.
3118 * Implemented the public key authentication in the initiator side
3119 in the server. Affected file silcd/protocol.c.
3121 * Removed the [RedirectClient] config section from the server
3122 configuration. Is not needed and I don't want to implement it.
3124 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Cleaned up the CMODE command in the server. It now works
3127 correctly and supports all the modes defined in the protocol.
3128 Affected file is silcd/command.c.
3130 * Added `hmac_name' field to the SilcChannelEntry in the server
3131 to hold the default HMAC of the channel. It can be set when
3132 creating the channel (with JOIN command). Affected files
3135 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3136 type to indicate the change of the current cipher and hmac
3137 on the channel. Client can safely ignore the <cipher> argument
3138 (if it chooses to do so) since the CHANNEL_KEY packet will
3139 force the channel key change anyway. The <hmac> argument is
3140 important since the client is responsible of setting the new
3141 HMAC and the hmac key into use.
3143 * Fixed the CMODE command in the client library as well.
3145 * Tested CMODE command in router environment successfully.
3147 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Show the version of the remote client (or server) when connecting
3150 to the server. It is logged to the log file. Affected file
3151 is silcd/protocol.c.
3153 * Fixed the KILLED notify handling in the client library. The
3154 client must be removed from all channels when receiving the
3157 Also, do not remove the client entry when giving the KILL
3158 command but when the KILLED notify is received.
3160 * Removed silc_idlist_find_client_by_nickname from the server.
3161 Not needed anymore. Affected files silcd/idlist.[ch].
3163 * Implemented the CHANNEL_CHANGE notify type handling to the
3164 server. Affected file silcd/server.c.
3168 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3170 * Added silc_server_send_notify_invite to send the INVITE
3171 notify between routers.
3173 * Implemented the INVITE command correctly to the server.
3175 * Implemented the INVITE notify type handling in the server.
3177 * Implemented the INVITE command to the client library and on the
3180 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Added function silc_server_get_client_resolve to find the
3183 client entry by ID from all ID lists and then resolve it
3184 (using WHOIS) if it cannot be found. Affected file is
3187 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * Implemented the BAN command to the client library.
3191 * The JOIN command in the server now checks the invite list
3194 * Changed the silc_command_reply_payload_encode_va and the
3195 silc_command_payload_encode_va to support that if argument is
3196 NULL it ignores and checks the next argument. Affected file
3197 lib/silccore/silccommand.c.
3199 * Added silc_server_send_notify_ban to send the BAN notify
3200 type between routers.
3202 * Chaned the silc_notify_payload_encode to support that if
3203 argument is NULL it ignores and checks the next argument.
3204 Affected file lib/silccore/silcnotify.c.
3206 * Tested ban lists in router environment successfully.
3208 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Implemented BAN command to the server, in silcd/command.[ch].
3212 * Removed the BAN and INVITE_LIST modes from the CMODE command
3215 * Added function silc_string_match to regex match two strings.
3216 Affected files lib/silcutil/silcutil.[ch].
3218 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Redefined parts of the SilcChannelEntry in the server to support
3221 the new ban and invite lists.
3223 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Redefined the INVITE command. The same command can be used to
3226 invite individuals to the channel but also to manage the invite
3227 list of the channel (to add to and remove from the invite list).
3228 Updated the protocol specs.
3230 * Added new command SILC_COMMAND_BAN that can be used to manage
3231 the ban list of the channel. Updated the protocol specs.
3233 * Removed the channel modes: the SILC_CMODE_BAN and the
3234 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3235 in the CMODE command. The equivalent features are now available
3236 using INVITE and BAN commands. Updated the protocol specs.
3238 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3239 in the network about change in the current ban list. The notify
3240 type is not used by the client.
3242 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3243 support the invite lists.
3245 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Added new function silc_string_regexify that converts string
3248 including wildcard characters into regex string that can
3249 be used by the GNU regex library. Added into the file
3250 lib/silcutil/silcutil.[ch].
3252 Added silc_string_regex_combine to combine to regex strings
3253 into one so that they can be used as one regex string by
3254 the GNU regex library. Added into the file
3255 lib/silcutil/silcutil.[ch].
3257 Added silc_string_regex_match to match two strings. It returns
3258 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3260 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Imported GNU regex to the soruce tree into lib/contrib.
3263 Fixed some compiler warning from the regex.c.
3265 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Fixed MOTD command in the server to work in router environment.
3269 * Fixed the MOTD command in the client library to support
3270 the server argument in the command.
3272 * Added `nickname_len' argument to the silc_idlist_add_client
3273 in the server, as the `nickname' argument may be binary data
3276 * Added silc_idlist_get_channels to return all channels from
3279 * Implemented LIST command to the server. Affected file is
3282 * Implemented the LIST command to the client library and on the
3285 * Added [<user count>] argument to the LIST command reply.
3286 With private channels the user count is not shown.
3288 * Updated TODO and README.
3290 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * The client entry's data.registered must be TRUE even with
3293 global client entry on global client list. The data.registered
3294 is used to check whether the client is anymore in the network,
3295 for example with WHOWAS command so it must be valid.
3297 * Fixed the WHOWAS command in the server. It now actually works
3298 in router environment. Added function into silcd/command_reply.c
3299 silc_server_command_reply_whowas_save.
3301 * Added silc_idlist_purge function to the silcd/idlist.c
3302 to periodically purge the ID Cache.
3304 * Fixed INFO command in the server. It works now in router
3305 environment. Added <server name> argument to the INFO command
3306 reply. Updated the protocol specs.
3308 * Fixed minor bug in silc_idcache_purge to not purge if the
3309 expire value is zero.
3311 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3312 they were buggy because of the WHOWAS information.
3314 * Fixed local command MSG to handle the async resolving of
3315 the remote client properly. It used to fail the first MSG.
3316 Affected file silc/local_command.c.
3318 * Added `data_len' field to SilcIDCache context.
3320 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3322 * Update TODO. Todo in commands in the server.
3324 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3327 used by routers as broadcast packet to inform other routers
3328 about the changed user mode.
3330 Implemented the notify handling in the server. Affected file is
3331 silcd/packet_receive.c. Added the function
3332 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3334 * Added new generic Channel Payload and deprecated the New Channel
3335 Payload. The New Channel Payload is now the generic Channel
3338 * Added new argument `mode' to the silc_server_send_new_channel
3339 as it is required in the Channel Payload now.
3341 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3342 and created a new and real SilChannelPayload to represent the
3343 new generic Channel Payload. Implemented the encode/decode
3344 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3346 * Added silc_server_get_client_channel_list to return the list
3347 of channels the client has joined for WHOIS command reply.
3348 Affected file silcd/server.[ch].
3350 * Implemented the channel list sending in the WHOIS command reply
3351 in server and in the client.
3353 Implemented the channel list displaying on the user interface
3354 as well. Affected file silc/client_ops.c.
3356 * Added silc_channel_payload_parse_list to parse list of Channel
3357 Payloads. It returns SilcDList list of SilcChannelPayloads.
3358 Client for example can use this function to parse the list of
3359 channels it receives in the WHOIS command reply. The caller
3360 must free the list by calling silc_channel_payload_list_free.
3361 Affected files lib/silccore/silcchannel.[ch].
3363 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Added one new argument <user mode> to the WHOIS command reply
3366 to return the mode of the user in SILC. Updated the protocol
3369 Implemented it to the server and client.
3371 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Fixed the mode printing on the user interface on joining.
3374 Affected file silc/client_ops.c.
3376 * Implemented the UMODE command and user modes in general to the
3377 client library and to the user interface.
3379 * Implemented the UMODE command to the server.
3381 * The server now sends UNKNOWN_COMMAND error status if client sends
3382 unknown command. Affected file silcd/command.c.
3384 * All server commands now handle the command identifier the right
3385 way when sending the command reply to the client. The client can
3386 use to identify the command replies with the identifier.
3388 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Added silc_server_get_client_route to resolve the route to
3391 the client indicated by the client ID. Affected file is
3394 * Added silc_server_relay_packet as general function to relay
3395 packet to arbitrary destination. This deprecates functions
3396 like _send_private_message_key, _relay_notify etc. Affected
3397 file is silcd/packet_send.[ch].
3399 Removed silc_server_send_key_agreement,
3400 silc_server_send_private_message_key and
3401 silc_server_packet_relay_notify functions from the file
3402 silcd/packet_send.[ch].
3406 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3407 server. Affected file silcd/packet_receive.[ch].
3409 * Implemented the KILL command to the client. Implemented the
3410 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3411 Affected files lib/silcclient/command[_reply].c and
3412 lib/silcclient/client_notify.c. Implemented the KILL notify
3413 printing in the user inteface.
3415 * Fixed a lot silc_parse_nick memory leaks from the client
3416 library in the file lib/silcclient/command.c.
3418 * Changed the silc_server_send_notify_on_channels's `sender'
3419 argument from SilcSocketConnection to SilcClientEntry to
3420 check the sender as entry and not as connection object and not
3421 to send to the client provided as argument. The affected file
3422 is silcd/packet_send.[ch].
3424 * The notify packets that are destined directly to the client used
3425 to not to be processed by the server. Now changed that and the
3426 server processes all notify packets. After relaying the packet
3427 to the client the notify packet is processed in the server.
3429 * The silc_server_free_client_data now checks whether there is
3430 pending outgoing traffic for the client and purges the data to
3431 the network before removing the client entry.
3433 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3436 an client is killed from the SILC Network. Updated the protocol
3439 Added new function silc_server_send_notify_killed to the
3440 silcd/packet_send.[ch].
3442 * Added function silc_server_packet_relay_notify to relay notify
3443 packets that are destined directly to a client. In this case
3444 the server does not process the notify packets but merely relays
3445 it to the client. Affected file silcd/packet_send.[ch].
3447 Added also silc_server_packet_process_relay_notify to check
3448 whereto relay the notify. Affected file is
3449 silcd/packet_receive.[ch].
3451 * Implemented the KILL command to the server.
3455 * Added the backup schema desgined last fall to the protocol
3456 specs for everyone to see. The specification is in the
3457 *-spec-xx.txt draft and the packet type definitions for the
3458 backup routers is in *-pp-xx.txt draft. Thusly, added also
3459 new packet type SILC_PACKET_CELL_ROUTERS.
3461 * A big security problem in the implementation discovered. The
3462 signoff of an client did not cause new channel key generation
3463 which it of course should've done. The channel keys must be
3464 always re-generated when client leaves (or signoffs) the channel.
3465 The silc_server_remove_from_channels funtion now handles
3466 the channel key re-generation.
3468 * Added `sender' argument to the silc_server_send_notify_on_channels
3469 to not to send the client provided as argument. Affected file
3470 silcd/packet_send.[ch].
3472 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3474 * Implemented OPER and SILCOPER commands into the server and
3477 * Added silc_auth_verify and silc_auth_verify_data to verify
3478 the authentication directly from the authentication payload.
3479 It supports verifying both passphrase and public key based
3480 authentication. Affected file lib/silccore/silcauth.[ch].
3482 * Added `hash' field to the SilcIDListData structure. It is the
3483 hash negotiated in the SKE protocol. Affected file is
3486 * Slight redesigning of the SilcAuthPayload handling routines.
3487 Do not send SilcPKCS but SilcPublicKey as argument.
3489 * Implemented the public key authentication support to the
3490 serverconfig. The public key is loaded from the provided path
3491 and saved as authentication data to void * pointer. Thus,
3492 changed the unsigned char *auth_data to void *auth_data;
3494 * Fixed SHUTDOWN command to send the reply before the server
3495 is shutdown. :) Affected file silcd/command.c.
3497 * Fixed fatal bug in CONNECT command. The hostname was invalid
3498 memory and server crashed. Affected file silcd/command.c.
3500 * Fixed fatal bug in CLOSE command. The server_entry became
3501 invalid but was referenced later in the command. Affected file
3504 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Fixed fatal bug in failure packet handling. Server ignored
3507 the failure and thus crashed when it came.
3511 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3513 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3514 that the command may be executed only once in (about) 2 seconds.
3515 The old SILC_CF_LAG flag is same but allows command bursts up
3516 to five before limiting.
3518 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3519 server code. Various commands now includes the CF_LAG_STRICT
3520 flag to disallow any kind of miss-use of the command.
3522 * Fixed the silc_buffer_unformat to not to allocate any data
3523 if the length of the data is zero. It used to allocate the
3524 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3526 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Changed the format of AdminConnection configuration section
3529 in the server. Added username of the admin to the format.
3530 Affected files silcd/serverconfig.[ch].
3532 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3533 to return admin configuration data by host, username and/or
3536 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3538 * Implemented WHOWAS command to the server. Added the functions:
3540 silc_server_command_whowas_parse,
3541 silc_server_command_whowas_send_reply,
3542 silc_server_command_whowas_from_client and
3543 silc_server_command_whowas_from_server
3545 * Added <Client ID> argument to the WHOWAS command reply. Updated
3546 the protocol specs accordingly.
3548 * Implemented WHOWAS command and command_reply to the client
3551 Implemented the WHOWAS printing on the user interface.
3553 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3555 * Added new argument to the WHOWAS command reply, the real name.
3556 It is an optional argument. Updated the protocol specs.
3558 * Added SilcIDCacheDestructor callback that is registered when
3559 the SilcIDCache is allocated. The callback is called when
3560 an cache entry in the ID Cache expires, or is purged from the
3561 cache. Added into lib/silccore/idcache.[ch].
3563 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3564 to destruct the client entries when the cache entry expires.
3565 Other ID Cache's in server and in the client library ignores
3568 * If the ID Cache entry's `expire' field is zero then the entry
3569 never expires. Added boolean `expire' argument to the
3570 silc_idcache_add function in the lib/silccore/idcache.[ch].
3571 If it is TRUE the default expiry value is used.
3573 * Added silc_server_free_client_data_timeout that is registered
3574 when client disconnects. By default for 5 minutes we preserve
3575 the client entry for history - for WHOWAS command.
3577 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Added support to the server to enforce that commands are not
3580 executed more than once in 2 seconds. If server receives
3581 commands from client more frequently, timeout is registered
3582 to process the commands. Affected file silcd/command.c.
3583 Added new function silc_server_command_process_timeout.
3585 * Changed NICK_NOTIFY handling in client library to check that
3586 if the client's nickname was changed, so there is no need to
3587 resolve anything from the server.
3589 * Removed error printing from the WHOIS and IDENTIFY commands.
3590 If error occurs then it is ignored silently in the client library.
3591 The application, however, may map the received error to
3592 human readable error string. The application currently maps
3593 the NO_SUCH_NICKNAME error to string.
3595 * Made the command status message public to the application. Moved
3596 them from lib/silcclient/command_reply.c to
3597 lib/silcclient/command_reply.h. The application can map the
3598 received command status to the string with the
3599 silc_client_command_status_message function.
3601 * Added check to the server to check that client's ID is same
3602 as the Source ID in the packet the client sent. They must
3605 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added dist-bzip hook to the Makefile.am to make bzip2
3608 compressed distributions.
3610 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3612 * Server now enforces the maximum length for the nickname and
3613 the channel as protocol specification dictates. 128 bytes for
3614 nickname and 256 bytes for channel name.
3616 * Moved the WHOIS printing to the application. The client libary
3617 does not print out the WHOIS information anymore, the application
3618 must do it. Renamed silc_client_command_reply_whois_print to
3619 the silc_client_command_reply_whois_save.
3621 The client's idle time is also sent to the application now, and
3622 the idle is shown on screen.
3624 * Added silc_client_command_reply_identify_save to save the
3625 received IDENTIFY entries.
3627 * Do not check for channel private keys in message sending and
3628 reception if the channel does not have the PRIVKEY mode set.
3629 Affected file lib/silclient/client_channel.c.
3631 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3634 just surfaced after chaning the JOIN procedure.
3636 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Added silc_client_get_clients_by_list to get client entries
3639 from Client ID list, that is returned for example by JOIN
3640 and USERS command replies. The application should use this
3641 function for example when JOIN command reply is received to
3642 resolve the clients already on the channel (library does not
3643 do that anymore as USERS command reply is not used in the JOIN
3644 procedure anymore). Affected files lib/silcclient/silcapi.h and
3645 lib/silcclient/idlist.c.
3647 * JOIN command reply and USERS command reply returns now SilcBuffer
3648 pointers instead of unsigned char pointers when returning
3649 the client list and mode list.
3651 * Added <Client ID> argument to the JOIN command reply, mainly
3652 for the server to identify for which client the command was
3653 originally sent. Updated protocol specs accordingly.
3655 * Added SilcDlist private_key pointer to the SilcChannelEntry
3656 in the client to support the channel private keys. Affected
3657 file is lib/silcclient/idlist.h.
3659 * Added SilcChannelPrivateKey argument to the function
3660 silc_client_send_channel_message so that application can choose
3661 to use specific private ke if it wants to. If it is not provided,
3662 the normal channel key is used, unless private keys are set.
3663 In this case the first (key that was added first) is used
3664 as the encryption key.
3666 * Implemented the support for channel private key handling.
3667 Implemented the following functions:
3669 silc_client_add_channel_private_key,
3670 silc_client_del_channel_private_keys,
3671 silc_client_del_channel_private_key,
3672 silc_client_list_channel_private_keys and
3673 silc_client_free_channel_private_keys
3675 Affected file lib/silcclient/client_channel.c.
3677 * Added the support for the private keys in the channel message
3678 sending and encryption and in the message reception and
3679 decryption. Affected funtions are
3680 silc_client_send_channel_message and silc_client_channel_message.
3682 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Added SKE's key verify callback to the client library's
3685 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3687 * Removed the statement that server (or router) must send USERS
3688 command reply when joining to the channel so that the client
3689 knows who are on the channel. Instead, the client list and
3690 client's mode list is now sent in the JOIN command reply to the
3691 client who joined channel. This is better solution.
3693 * Added function silc_server_get_users_on_channel and function
3694 silc_server_save_users_on_channel to the silcd/server.[ch].
3696 * Removed function silc_server_command_send_users from the
3699 * Do not show topic on the client library anymore. The topic is
3700 sent in the command reply notify to the application and the
3701 application must show the topic now.
3703 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Added client searching by nickname hash into the IDENTIFY and
3706 WHOIS commands in the server as they were clearly missing from
3707 them. Affected file is silcd/command.c.
3709 * Fixed a bug in private message receiving in the client library.
3710 The remote ID was freed and it wasn't supposed, now it is
3713 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3715 * Minor fix to the channel payload; allocate the data area, as it
3716 needs to be of specific length.
3718 * If the key agreement port is zero then the operating
3719 system will define the bound port. Affected files are
3720 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3722 * Added new function silc_channel_payload_decrypt into the file
3723 lib/silccore/silcchannel.[ch].
3725 * Moved the channel message etc, check from silc_packet_decrypt
3726 to applications. The library calls now a generic
3727 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3728 when the packet is either normal or special. This was done to
3729 allow more wide range of checking that was not allowed when
3730 the code was in library. Now applications can do virtually any
3731 checks to the packet and return to the library the decision how
3732 the packet should be processed. Affected files are
3733 lib/silccore/silcpacket.[ch].
3735 Added silc_server_packet_decrypt_check to the server and
3736 silc_client_packet_decrypt_check to the client library.
3738 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3739 to send with specified source and destination information.
3741 * Channel message delivery between routers was broken after the
3742 channel key distribution was fixed earlier. The channel key
3743 was used be to distributed to other routers as well which is not
3744 allowed by the protocol. Now this is fixed and channel keys
3745 really are cell specific and the channel message delivery between
3746 routers comply with the protocol specification.
3748 * Fixed various commands in server to check also the global list
3749 for the channel entry and not just the local list. The affected
3750 file silcd/command.c.
3752 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Added assert()s to buffer formatting and unformatting routines
3755 to assert (if --enable-debug) when error occurs. Affected
3756 file: lib/silcutil/silcbuffmt.c.
3758 * Changed to auto-reconnect to check whether the remote host is
3759 router and register the re-connect timeout if it is. It used
3760 to check that whether we are normal server, but router must do
3761 auto-reconnect with another router as well. Affected file
3764 * Removed the [<key len>] option from CMODE command as the cipher
3765 name decides the key length, nowadays. See the defined ciphers
3766 from the protocol specification.
3768 * Added [<hmac>] option to the CMODE command to define the HMAC
3769 for the channel. Added SILC_CMODE_HMAC channel mode.
3771 * Added [<hmac>] option for the JOIN command so that user can
3772 select which HMAC is used to compute the MACs of the channel
3775 * Added Hmac field to the Channel Message Payload. The integrity
3776 of plaintext channel messages are now protected by computing
3777 MAC of the message and attaching the MAC to the payload. The
3778 MAC is encrypted. Now, it is clear that this causes some
3779 overhead to the size of the packet but rationale for this is that
3780 now the receiver can verify whether the channel message decrypted
3781 correctly and also when private keys are set for the channel the
3782 receiver can decrypt the packet with several keys and check from
3783 the MAC which key decrypted the message correctly.
3785 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3786 lib/silccrypt/silccipher.[ch].
3788 * Added silc_hash_len to return the digest length into the
3789 lib/silcrypt/silchash.[ch].
3791 * Rewrote parts of Silc Channel Payload interface in the
3792 lib/silccore/silcchannel.[ch]. The encode function now also
3793 encrypts the packet and parse function decrypts it.
3795 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Fixed a minor formatting bug in the SKE's key material processing.
3798 It actually might have processed the keys wrong way resulting
3801 * Redefined the mandatory HMAC algorithms and added new algorithms.
3802 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3803 and hmac-md5 truncated to 96 bits. The mandatory is now
3804 hmac-sha1-96. Rest are optional (including the one that used
3805 to be mandatory). Rationale for this is that the truncated HMAC
3806 length is sufficient from security point of view and can actually
3807 make the attack against the HMAC harder. Also, the truncated
3808 HMAC causes less overhead to the packets. See the RFC2104 for
3811 * Added new [hmac] configuration section. The SKE used to use
3812 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3813 is of course wrong. The official names that must be proposed in
3814 the SKE are the ones defined in the protocol specification
3815 (hmac-sha1-96 for example). The user can configure any hmac
3816 using any hash function configured in the [hash] section. At
3817 least, the mandatory must be configured.
3819 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3821 * Added HMAC list to the SKE proposal list. It has now both
3822 hash algorithm list and HMAC list. This makes the protocol
3823 incompatible with previous versions. The SKE now seems to work
3824 the way it is supposed to work, for the first time actually.
3826 * Defined plain Hash algorithms to the protocol specification.
3829 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Implemented support for key agreement packets into the server.
3832 Added functions silc_server_key_agreement and
3833 silc_server_send_key_agreement. Other than these functions,
3834 server has nothing to do with this packet.
3836 * Added support for private message key packets into the server.
3837 Added functions silc_server_private_message_key and
3838 silc_server_send_private_message_key.
3842 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3843 called in the protocol's final callback instead in the END
3844 protocol state. This makes a little more sense and in the same
3845 time in client we can use the same protocol routines for normal
3846 key exchange and to key agreement packet handling as well.
3848 * Added to both client's and server's KE protocol context the
3849 SilcSKEKeyMaterial pointer to save the key material. We will
3850 bring the key material to the protocol's final callback by doing
3851 this. The final callback must free the key material.
3853 * Added SKE's packet_send callback into client's KE protocol
3854 context so that the caller can choose what packet sending function
3855 is used. This way we can use different packet sending when
3856 doing normal SKE when doing key agreement packet handling (in
3857 the key agreement packet handling we do not want to encrypt
3860 * Implemented the responder side of the key agreement routines
3861 in the client. The client can now bind to specified port and
3862 accept incoming key negotiation. The key material is passed
3863 to the application after the protocol is over.
3865 * Implemented the processing of incoming Key Agreement packet
3866 in the client. Added function silc_client_key_agreement to
3869 * Implemented the intiator side of the key agreement routines
3870 in the client. The client can now initiate key agreement with
3871 another remote client. The key material is passed to the
3872 application after the protocol is over.
3874 * Created client_keyagr.c to include all the key agreement
3877 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3878 SILC_TASK_CALLBACK except that it is not static.
3880 * Created client_notify.c and moved the Notify packet handling
3881 from the client.[ch] into that file.
3883 * Created client_prvmsg.c and moved all private message and
3884 private message key routines from the client.[ch] into that file.
3886 * Create client_channel.c and moved all channel message and
3887 channel private key routines from the client.[ch] into that file.
3889 * Changed silc_client_get_client_by_id_resolve to resolve with
3890 WHOIS command instead of IDENTIFY command, in the file
3891 lib/silclient/idlist.c.
3893 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3895 * Implemented the SKE's responder side to the Client library.
3897 * When FAILURE is received to the protocol do not trust it
3898 blindly. Register a timeout to wait whether the remote closes
3899 the connection as it should do it, only after that process the
3900 actual failure. This was changed to both client and server.
3902 * Added client_internal.h to include some of the structures
3903 there instead of client.h in lib/silcclient/.
3905 * Added function silc_task_unregister_by_callback to unregister
3906 timeouts by the callback function.
3908 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Some "Incomplete WHOIS info" errors has been appearing on the
3911 log files. Took away the entry->userinfo check from WHOIS
3912 reply sending. The entry->userinfo is now " " if client did not
3913 provide one. I thought this was fixed earlier but something
3914 is wrong still. Let's see if the error still appears.
3916 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Fixed a minor bug in the login when the channel key is
3919 re-generated in the server. It used to generate the key in
3920 wrong order and thus caused problems in the channel traffic.
3922 * Fixed a minor bug in channel key distsribution after
3923 KICK command. The key was not sent to the router even though
3926 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Added silc_ske_process_key_material_data as generic routine
3929 to process any key material as the SILC protocol dictates. The
3930 function is used by the actual SKE library but can be used by
3931 applications as well. This relates to the private message keys
3932 and the channel private keys since they must be processed the
3933 same way the normal SILC session keys. The protocol dictates
3934 this. Affected files: lib/silcske/silcske.[ch].
3936 Added also silc_ske_free_key_material to free the
3937 SilcSKEKeyMaterial structure.
3939 * Defined silc_cipher_set_key function to set the key for
3940 cipher without using the object's method function. The affected
3941 files: lib/silccrypt/silccipher.[ch].
3943 * Implemented silc silc_client_add_private_message_key,
3944 silc_client_add_private_message_key_ske,
3945 silc_client_del_private_message_key,
3946 silc_client_list_private_message_keys and
3947 silc_client_free_private_message_keys functions in the
3950 Added functions silc_client_send_private_message_key to send
3951 the Private Message Key payload and silc_client_private_message_key
3952 to handle incoming Private Message Key payload.
3954 * Added Cipher field to the Private Message Key payload to set
3955 the cipher to be used. If ignored, the default cipher defined
3956 in the SILC protocol (aes-256-cbc) is used.
3958 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Removed lib/silcclient/ops.h file.
3962 Redefined parts of the SILC Client Library API. Created new
3963 file silcapi.h that deprecates the ops.h file and defines the
3964 published Client Library API. Defined also private message key
3965 API and channel private key API into the file.
3967 This is the file that the application must include from the
3968 SILC Client Library. Other files need not be included by
3969 the application anymore.
3971 * Added new key_agreement client operation callback and also
3972 defined the Key Agreement library API for the application.
3974 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3977 is used by clients to request key negotiation between another
3978 client in the SILC network. If the negotiation is started it
3979 is performed using the SKE protocol. The result of the
3980 negotiation, the secret key material, can be used for example
3981 as private message key.
3983 Implemented the Key Agreement payload into the files
3984 lib/silccore/silauth.[ch].
3986 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Redefined ciphers for the SILC protocol. Added some new ciphers
3989 and defined the key lengths for the algorithms. Changed the
3990 code accordingly. The default key length is now 256 bits.
3992 * Fixed SKE key distribution function silc_ske_process_key_material
3993 when the key length is more than 128 bits. The default key
3994 length in SILC is now 256 bits.
3996 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3997 to indicate unsupported algorithm.
3999 * Renamed rijndael.c to aes.c and all functions as well.
4001 * Fixed a long standing channel key setting bug in client library.
4002 Weird that it has never surfaced before.
4004 * Fixed bug in channel deletion. If the entire channel is removed
4005 then it must also delete the references of the channel entry
4006 from the client's channel list as the client's channel entry and
4007 the channel's client entry share same memory.
4009 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Implemented CONNECT and SHUTDOWN commands in the client.
4013 * Implemented CLOSE command to the client.
4015 * Added the function silc_idlist_find_server_by_name into the
4016 files silcd/idlist.[ch].
4018 Added the function silc_idlist_find_server_by_conn into the
4019 files silcd/idlist.[ch].
4021 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * DIE command was renamed to SHUTDOWN. Updated the both code
4026 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4027 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4029 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4032 * Added function silc_server_create_connection function to create
4033 connection to remote router. My server implementation actually
4034 does not allow router to connect to normal server (it expects
4035 that normal server always initiates the connection to the router)
4036 so the CONNECT command is only good for connecting to another
4039 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4041 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4042 or some other client was kicked from the channel.
4044 Implemented the handling of the notify type to both client
4047 Implemented silc_server_send_notify_kicked to send the KICKED
4048 notify. It is used to send it to the server's primary router.
4050 * Implemented the KICK command into server and client.
4052 * Added `query' argument to the silc_idlist_get_client function
4053 to indicate whether to query the client from server or not if
4056 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4057 to indicate that the client is not channel founder.
4061 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4063 * Removed the rng context from SilcPacketContext structure and
4064 changed that the packet routine uses the Global RNG API.
4066 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4068 * Added support for quit message that client can "leave" on the
4069 channel when it quits the SILC. It is ditributed inside the
4070 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4072 Added silc_server_free_client_data that will take the
4073 signoff message as argument.
4075 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4077 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Updated parts of the protocol specification to keep it up
4082 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4085 payloads in one packet.
4087 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4088 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4089 use now the new List flag.
4091 * Also deprecated the following packet types: REPLACE_ID,
4092 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4094 * Added list support for Notify packet in server.
4096 * Added silc_server_send_notify_channel_change to send the
4097 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4098 the silc_server_send_replace_id.
4100 * Added silc_server_send_notify_nick_change to send the
4101 NICK_CHANGE notify type. Deprecates the function
4102 silc_server_send_replace_id.
4104 * Added silc_server_send_notify_join to send the JOIN notify type.
4105 Deprecates the function silc_server_send_new_channel_user.
4107 * Added silc_server_send_notify_leave to send LEAVE notify type.
4108 Deprecates the function silc_server_send_remove_channel_user.
4110 * Added silc_server_send_notify_cmode and
4111 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4112 types. Deprecates the silc_server_send_set_mode function.
4114 * Added SERVER_SIGNOFF notify type to indicate that server has
4115 quit. This means that all clients on the channel from that
4116 server will drop. This can be also used when netsplit happens.
4118 Deprecated REMOVE_ID packet type since it is not needed anymore
4121 Added silc_server_send_notify_server_signoff to send the
4122 SERVER_SIGNOFF notify type. Deprecates the function
4123 silc_server_send_remove_id.
4125 Added also silc_server_send_notify_signoff to send the
4126 SIGNOFF notify type.
4128 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4129 SILC protocol from this day on. Changed the protocol
4130 specification as well.
4132 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4133 notify type. It is used between routers to notify about
4134 topic changes on a channel.
4136 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4139 * Partly updated the protocol specification to comply with the
4140 changes now made. It is still though a bit outdated.
4142 * The JOIN notify type now takes one extra argument <Channel ID>.
4143 The packet used to be destined to the channel but now the
4144 JOIN type may be sent as list thus it is impossible to
4145 destine it to any specific channel. By adding this argument
4146 it is again possible.
4148 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4150 * Added CREDITS file. The CHANGES and CREDITS file will appear
4151 in the distribution as well.
4153 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4156 types in the server's silcd/packet_receive.c.
4158 * Implemented CMODE and CUMODE to work in router environment.
4160 * Fixed minor encoding and decoding buglet from the
4161 lib/silccore/silcmode.c.
4163 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4166 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4168 * Changed all SilcConfigServer* and silc_config_server* to
4169 SilcServerConfig* and silc_server_config*, respectively.
4172 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Associated the ID (client or server ID) to the Authentication
4175 Payload to avoid any possibility of forging. Updated the
4176 protocol specification and the code accordingly.
4178 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * The RSA key length is now save to the RsaKey context in the
4181 key generation process in lib/silccrypt/rsa.c. The key length
4182 is now used to figure out the maximum size of the block allowed
4183 to be encrypted/signed.
4185 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4186 is equivalent to the silc_mp_mp2bin but does not allocate any
4189 * Changed silc_mp_mp2bin API to take length argument. If it is
4190 non-zero then the buffer is allocated that large. If zero, then
4191 the size is approximated using silc_mp_sizeinbase, which however
4194 * Created Global RNG API which is global RNG that application can
4195 initialize. After initializing, any routine anywhere in the
4196 code (including library) can use RNG without allocating a new
4197 RNG object. This was done to allow this sort of use of the
4198 RNG in code that has no chance to allocate RNG object. All
4199 applications currently allocate this and many routines in the
4200 library use this. Affected file lib/silccrypt/silcrng.[ch].
4202 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4203 it to use the Global RNG API.
4205 * Defined Authentication Payload into protocol specification that
4206 is used during SILC session to authenticate entities. It is
4207 used for example by client to authenticate itself to the server
4208 to obtain server operator privileges.
4210 Implemented this payload into the lib/silccore/silcauth.[ch].
4211 Implemented also routines for public key based authentication
4212 as the new protocol specification dictates.
4214 Moved definitions of different authentication methods from
4215 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4217 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4218 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4219 silc_pkcs_verify_with_hash functions into the file
4220 lib/silccrypt/silcpkcs.[ch].
4222 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * The client entry's userinfo pointer must be always valid.
4225 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4226 will fail since it requires the userinfo. Now, the userinfo
4227 is allocated as "" if actual userinfo does not exist. Actually,
4228 it must exist and it is totally Ok to drop client connections
4229 that does not announce the userinfo. However, we will make
4230 this workaround for now.
4232 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4233 to return the remote port by socket.
4235 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4238 SILC_SERVER_PENDING_EXEC and added an new macro
4239 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4240 data or when error occurs while processing the pending command.
4242 Added new argument `destructor' into silc_server_command_pending
4243 and to the SilcServerCommandPending object. This destructor is
4244 now called after calling the pending callback or if error occurs
4245 immediately. If error occurs the actual pending callback won't
4246 be called at all - only the destructor. The destructor may be
4247 NULL if destructor is not needed.
4249 All this applies for client library code as well. Similar
4250 changes were made there as well for the pending commands.
4252 In the client, the application must now allocate the
4253 SilcClientCommandContext with the silc_client_command_alloc
4256 * Added reference counter to the SilcServerCommandContext. Added
4257 function silc_server_command_alloc and silc_server_command_dup
4260 Same type of functions added to the client library for the same
4263 * Removed the cmd_ident from IDListData away since it is now
4264 global for all connections. It is the command identifier used
4265 in command sending and with pending commands. The affected file
4268 * Added reference counter to the SilcSocketConnection objecet to
4269 indicate the usage count of the object. The object won't be
4270 freed untill the reference counter hits zero. Currently only
4271 server uses this, and client ignores it. The client must be
4272 set to use this too later. The affected files are
4273 lib/silccore/silcsockconn.[ch]. Added also the function
4274 silc_socket_dup to increase the reference counter.
4276 This was mainly added because it is possible that the socket
4277 is removed underneath of pending command or other async
4278 operation. Now it won't be free'd and proper DISCONNECTING
4279 flags, etc. can be set to avoid sending data to connection that
4280 is not valid anymore.
4282 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4283 the connection. After that it sets SILC_SET_DISCONNECTED.
4284 It is, however, possible that the socket data is not still freed.
4285 The silc_server_packet_process now checks that data is not
4286 read or written to connection that is DISCONNECTED. The socket
4287 get's freed when the reference counter hits zero.
4289 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Changed the client operation API: channel_message operation's
4292 `sender' is now the client entry of the sender, not the nickname
4293 and the `channel' is the channel entry, not the channel name.
4295 In the private_message operation the `sender' is now also the
4296 client entry of the sender not the nickname.
4298 Affected file is lib/silcclient/ops.h and all applications
4299 using the client operations.
4301 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Moved the calling of ops->connect() from connect_to_server_final
4304 into receive_new_id functin since that is the point when the
4305 client is actually allowed to send traffic to network. The
4306 affected file is lib/silcclient/client.c.
4308 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4311 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4312 (if needs broadcasting) instead of broadcasting the packets one
4313 by one which would make a burst in the network traffic.
4315 * Added `broadcast' argument to the functions in silcd/server.[ch]
4316 silc_server_create_new_channel[_with_id] to indicate whether
4317 to send New Channel packet to primary router.
4319 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Added new function into the silcd/server.[ch] files:
4322 silc_server_create_new_channel_with_id to create new channel with
4323 already existing Channel ID.
4325 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4326 lib/silccore/silcpacket.h. This packet is used t send list of
4327 Set Mode payloads inside one packet. Server uses this to set
4328 the modes for the channels and clients on those channels, that it
4329 announced to the router when it connected to it. The protocol
4330 specification has been updated accordingly.
4332 * The silc_server_new_channel did not handle the packet coming
4333 from normal server as it normally does not send that. However,
4334 when it announces its channels it does send it. Implemented
4335 the support for that.
4337 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4338 into the file lib/silccore/id.h.
4340 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4342 * Fixed memory leaks in the functions silc_idlist_del_client,
4343 silc_idlist_del_channel and silc_idlist_del_server in the file
4344 silcd/idlist.c. All of those leaked like a sieve.
4346 * Fixed some small memory leaks in the client's function
4347 silc_client_notify_by_server.
4349 * Added functions into silcd/server.c: silc_server_announce_clients,
4350 silc_server_announce_channels and silc_server_announce_server.
4351 These functions are used by normal and router server to announce
4352 to its primary router about clients, channels and servers (when
4353 router) that we own. This is done after we've connected to the
4356 These functions effectively implements the following packet types:
4357 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4358 and SILC_PACKET_NEW_ID_LIST.
4360 * Added new functions into the silcd/packet_receive.[ch]:
4361 silc_server_new_id_list, silc_server_new_channel_list and
4362 silc_server_new_channel_user_list to handle the incoming
4363 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4365 * Added support of changing Channel ID in the function
4366 silc_server_replace_id. If the server that announces a channel
4367 to the router already exists in the router (with same name but
4368 with different Channel ID), router is responsible to send
4369 Replace ID packet to the server and force the server to change
4370 the Channel ID to the one router has.
4372 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4373 client that the Channel ID has been changed by the router. The
4374 normal server sends this to the client. Client must start using
4375 the new Channel ID as the channel's ID.
4377 Implemented handling of this new type into lib/silcclient/client.c
4378 into the function silc_client_notify_by_server.
4380 * Added new function silc_idlist_replace_channel_id into the files
4381 silcd/idlist.[ch] to replace the Channel ID.
4383 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Call silc_server_command_identify_check always when processing
4386 the IDENTIFY command in silcd/command.c
4388 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4391 send keepalive packets. The packet can be sent by clients,
4392 servers and routers.
4394 Added function silc_socket_set_heartbeat into the file
4395 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4396 If not set, the heartbeat is not performed. The actual
4397 heartbeat is implemented in the low level socket connection
4398 library. However, application is responsible of actually
4401 Added silc_server_send_heartbeat to send the actual heartbeat
4402 packet into silcd/packet_send.[ch]. Server now performs
4403 keepalive with all connections.
4405 * Added silc_task_get_first function into lib/silcutil/silctask.c
4406 to return the timeout task with shortest timeout. There was a bug
4407 in task unregistration that caused problems. TODO has been
4408 updated to include that task system must be rewritten.
4410 * The client library will now resolve the client information when
4411 receiving JOIN notify from server for client that we know but
4412 have incomplete information.
4414 * Rewrote parts of silc_server_remove_from_channels and
4415 silc_server_remove_from_one_channel as they did not remove the
4416 channel in some circumstances even though they should've.
4418 * Encryption problem encountered in server:
4420 The LEAVE command used to send the Channel Key packet to the
4421 router immediately after generating it. However, the code
4422 had earlier sent Remove Channel user packet but not immediately,
4423 ie. it was put to queue. The order of packets in the router
4424 was that Channel Key packet was first and Remove Channel User
4425 packet was second, even though they were encrypted in the
4426 reverse order. For this reason, MAC check failed. Now, this
4427 is fixed by not sending the Channel Key packet immediately but
4428 putting it to queue. However, this is more fundamental problem:
4429 packets that are in queue should actually not be encrypted
4430 because packets that are sent immediately gets encrypted
4431 actually with wrong IV (and thus MAC check fails). So, packets
4432 that are in queue should be encrypted when they are sent to
4433 the wire and not when they put to the queue.
4435 However, the problem is that the current system has not been
4436 designed to work that way. Instead, the packet is encrypted
4437 as soon as possible and left to the queue. The queue is then
4438 just purged into wire. There won't be any fixes for this
4439 any time soon. So, the current semantic for packet sending
4442 o If you send packet to remote host and do not force the send
4443 (the packet will be in queue) then all subsequent packets to the
4444 same remote host must also be put to the queue. Only after the
4445 queue has been purged is it safe again to force the packet
4448 o If you send all packets immediately then it safe to send
4449 any of subsequent packets through the queue, however, after
4450 the first packet is put to queue then any subsequent packets
4451 must also be put to the queue.
4453 Follow these rules and everything works fine.
4455 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Added new function silc_server_remove_clients_by_server to
4458 remove all client entries from ID list when the server connection
4459 is lost. In this case it is also important to invalidate all
4460 client entires as they hold the invalid server entry. This
4461 fixes fatal bug when server has lost connection and will reconnect
4464 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Made some sanity checks to silc_server_daemonise like to check
4467 whether the requested user and group actually exists.
4469 * Added sanity check to SKE's silc_ske_responder_finish to check
4470 that the public and private key actually is valid.
4472 * Invalidate the client's nickname when receiving Replace ID
4473 packet and the Client ID is being replaced. This means that the
4474 server will query the nickname if someone needs it (client)
4477 * Sort the ID Cache in client library when the ID Cache data
4478 has changed (needs sorting).
4480 * Do not allow for SILC client to create several connections to
4481 several servers. The client does not support windows right now
4482 and generating multiple connections causes weird behaviour.
4484 Irssi-silc client does support windows and can handle several
4485 connections without problems, see: www.irssi.org and SILC plugin.
4487 * Fixed some places where client was added to the IDList. The
4488 rule of thumb is following (in order to get everything right):
4489 If the client is directly connected local client then the
4490 `connection' argument must be set and `router' argument must be
4491 NULL to silc_idlist_add_client function. If the client is not
4492 directly connected client then the `router' argument must
4493 bet set and the `connection' argument must be NULL to the
4494 silc_idlist_add_client function.
4496 * The funtion silc_server_packet_send_local_channel actually did
4497 not check whether the client was locally connected or not. It
4498 does that now. Fixed a bug related to LEAVE command.
4500 * Fixed Remove Channel User payload parsing bug in server's
4501 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4503 * The server's silc_server_save_channel_key now checks also the
4504 global ID list for the channel as it might not be in the local
4505 list. Fixed a bug related to LEAVE command.
4507 * Is this the end of the [<unknown>] buglet that has been lurking
4508 around for a long time? A little for loop fix in server's
4509 silc_server_command_whois_parse that is used by both IDENTIFY
4510 and WHOIS command. At least, this was a clear bug and a cause
4511 of one type of [<unknown>] buglet.
4513 * WHOIS and IDENTIFY commands call the function
4514 silc_server_command_[whois/identify]_check function even if
4515 we are not router server.
4517 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Added --with-gmp configuration option. If set the GMP
4520 is always compiled in the SILC source tree. If not set then
4521 it is checked whether the system has the GMP3 installed. If
4522 it has then the GMP won't be compiled (the system's headers
4523 and library is used), if it doesn't have it then the GMP is
4524 compiled in the SILC source tree.
4526 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Changed RSA private exponent generation to what PKCS #1
4529 suggests. We try to find the smallest possible d by doing
4530 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4531 not security fix but optimization.
4533 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4535 * Added new config entry [Identity] to fork the server and run
4536 it as specific user and group. A patch from Bostik.
4538 * Imported Dotconf configuration library into lib/dotconf.
4539 This will be used to create the SILC configuration files later.
4540 It will appear in the distsribution after this commit.
4542 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * A big code auditing weekend happening. Auditing code for
4545 obvious mistakes, bugs and errors. Also, removing any code
4548 Removed files for being obsolete:
4550 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4551 inline in the file lib/silcutil/silcbuffer.h)
4553 o lib/silcutil/silcbufutil.c (the header has inline versions)
4555 Changed code to fix possible error conditions:
4557 o The buffer formatting routines now check that the destination
4558 buffer really has enough space to add the data. This applies for
4559 both buffer formatting and unformatting
4560 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4561 unformatting was changed to accomodate following rules:
4562 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4563 sent to the function while XXX_*STRING will not allocate or copy
4564 the data into the buffer. Instead it sets the pointer from the
4565 buffer into the pointer sent as argument (XXX_*STRING used to
4566 require that the pointer must be allocated already). This change
4567 makes this whole thing a bit more consistent and more optimized
4568 (note that the data returned in the unformatting with XXX_*STRING
4569 must not be freed now). The routines return now -1 on error.
4571 o Tried to find all code that use buffer_format and buffer_unformat
4572 and added return value checking to prevent formatting and
4573 especially unformatting errors and possible subsequent fatal
4576 o Changed ske->x and ske->KEY to mallocated pointers in
4577 lib/silcske/silcske.h. Fixed possible data and memory leak.
4579 o Added return value checking to all *_parse* functions. Fixed
4580 many memory leaks as well.
4582 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4583 so that buffer overflows would not happen. All code now also
4584 checks the return value as it can fail.
4586 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Added reconnection support to server if the normal server looses
4589 its connection to the router (for example if router is rebooted).
4590 The server performs normal reconnection strategy implemented
4591 to the server. Affected file silcd/server.c.
4593 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Added new packet type SILC_PACKET_SET_MODE that is used to
4596 distribute the information about changed modes (for clients,
4597 channels and clients channel modes) to all routers in the
4598 network. Updated the protocol specification accordingly.
4600 Added functions into silcd/packet_send.c and
4601 silcd/packet_receive.c: silc_server_send_set_mode,
4602 silc_server_set_mode.
4604 Added new files silcmode.[ch] into lib/silccore that implements
4605 the encoding and decoding of Set Mode Payload. Added new type
4606 SilcSetModePayload. Moved the definitions of different modes
4607 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4609 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Oops, a little mistake in server's connection authentication
4612 protocol. The protocol is not ended with FAILURE but with
4613 SUCCESS if the authentication is Ok. :) Affected file is
4616 * Implemented NICK_CHANGE notify handling in server in the file
4617 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4618 the local clients on the channel. After the changing nickname
4619 in router environment snhould work and the [<unknown>] nickname
4620 should appear no more.
4622 The silc_server_replace_id function that receives the Replace ID
4623 payload now sends the NICK_CHANGE notify type also in the file
4624 silcd/packet_receive.c
4626 * Changed WHOIS and IDENTIFY command to support the maximum amount
4627 of arguments defined in protocol specs (3328 arguments). This
4628 fixed a bug that caused problems when there were more than three
4631 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added extra parameter, command identifier, to the
4634 silc_client_send_command so that explicit command identifier
4637 Changed that ID list routines uses specific command identifier
4638 when sending WHOIS/IDENTIFY requests to the server so that they
4639 can be identified when the reply comes back.
4641 Affected files lib/silcclient/command.[ch],
4642 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4644 * Added `sender' argument to silc_server_packet_send_to_channel
4645 to indicaet the sender who originally sent the packet to us
4646 that we are now re-sending. Ignored if NULL. Affected file
4647 silcd/packet_send.[ch].
4649 * Added some server statistics support in silcd/server_internal.h
4650 SilcServerStatistics structure and around the server code. Also
4651 send some nice statistics information when client is connecting
4654 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Fixed channel ID decoding in server's JOIN command reply in
4657 silcd/command_reply.c
4659 * Fixed braodcasting of replace ID payload to not to send it if
4660 we are standalone server in silcd/packet_receive.c.
4662 * Fixed all channel message sending routines to not to send
4663 packets to clients that has router set, since they are routed
4664 separately in the same function earlier. Affects file
4665 silcd/packet_send.c and all channel packet sending functions.
4667 * In USERS reply, res_argv[i] are not allocated, the table
4668 is allocated. Thus changed that free the table, not its
4671 * In server's whois_check and identify_check if the client is
4672 locally connected do not send any WHOIS commands - they are not
4675 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Fixed some minor bugs in client when sending WHOIS command. The
4678 arguments was in wrong order.
4680 * Removed statis function add_to_channel from server in
4681 silcd/command.c that was previously used with the joining but
4684 * Tested USERS command in router environment successfully with two
4685 routers, two servers and two clients.
4687 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Reorganized the USERS command and command reply in client library
4690 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4691 When the command is given by user we register a pending command
4692 callback that will reprocess the command after the reply has been
4693 received from the server. When reprocessing the packet we then
4694 display the information. Thus, the USERS information is displayed
4695 now in the command callback instead of in the command reply
4696 callback. The processing of the command is same as previously
4697 when server has sent the command reply in the JOINing process.
4699 * Added to USERS command in silcd/command_reply.c to join the client,
4700 we didn't use to know about, to the channel after we've created
4701 a client entry for it. Also, for clienet we did know already still
4702 check whether it is on the channel or not and add it if not.
4704 * Removed silc_server_command_join_notify as the function and its
4707 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Changed the client's pending command handling to the same as the
4710 server's pending command handling. It is also now possible to
4711 execute command reply functions from other command reply
4712 function as the function callbacks for commands and command
4713 replies are one and same. The pending commands are not static
4714 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4715 in client connection context. Thus, pending commands are server
4716 connection specific as it is convenient.
4718 Changed the function silc_client_command_pending and
4719 silc_client_command_pending_del and added new function
4720 silc_client_command_pending_check. Removed the
4721 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4724 * Added cmd_ident, current command identifier, to the client
4725 connection context in lib/silcclient/client.h to keep track on
4726 command identifiers used in command sending. Client's command reply
4727 function handling now supports the mandatory command identifiers.
4729 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4730 funtions in client to fully support pending command callbacks.
4732 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4733 as one of the arguments to the application in the command reply
4736 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4737 before first releasing SILC but came back. Now it is removed again
4738 and should come back nomore. The FORWARDED flag was used only
4739 by the JOINing procedure by forwarding the command packet to router.
4740 Now, the JOINing procedure has been changed to more generic (due
4741 to various router environment issues) and FORWARDED is not needed
4742 anymore for anything. The protocol specification is yet to be
4745 Now, removed silc_server_packet_forward from server and the flag
4746 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4748 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Renamed NAMES command to USERS command. The NAMES was named that
4751 due to historical reasons. Now it is renamed. Also, rewrote
4752 parts of the USERS command. The nickname list is not sent anymore
4753 by the server. Only Client ID and mode lists are sent in the USERS
4754 command. Changed this also to the protocol specification.
4756 The client now resolves the names and stuff after it receives
4757 the USERS list from the server when joining to the channel.
4759 * WHOIS and IDENTIFY commands has been changed to support multiple
4760 Client ID's per command. One can now search for multiple users
4761 in the network by sending only one WHOIS or IDENTIFY command.
4762 Changed the code and the protocol specifications.
4764 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4765 uses silc_server_command_whois_parse to parse the request. */
4767 * If normal server, do not parse the WHOIS and IDENTIFY requests
4768 before sending it to the router. Saves some time.
4770 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4772 * Fixed JOIN command on client library. Wrong number of arguments
4773 used to crash the client.
4775 * Added silc_server_channel_has_global function to check whether
4776 channel has global users or not.
4778 * Added silc_server_channel_has_local function to check whether channel
4779 has locally connected clients on the channel.
4781 * The silc_server_remove_from_one_channel now checks whether the
4782 channel has global users or not after given client was removed from
4783 the channel. It also checks whether the channel has local clients
4784 on the channel anymore. If it does not have then the channel entry
4785 is removed as it is not needed anymore.
4787 * The silc_server_notify now checks on JOIN notify whether the joining
4788 client is one of locally connected or global. If it is global then
4789 the channel has now global users on the channel and that is marked
4790 to the channel entry. Also, it now saves the global client to
4791 global list who is joining and JOINs it to the channel. This is
4792 for normal server, that is.
4794 Changed silc_server_send_notify_on_channel,
4795 silc_server_packet_relay_to_channel and
4796 silc_server_packet_send_to_channel check if we are normal server
4797 and client has router set (ie. global client) do not send the
4798 message to that client, as it is already routed to our router.
4800 * Implemented LEAVE notify type handling in silc_server_notify
4803 * Tested LEAVE command in router environment successfully. Tested
4804 with two routers, two servers and two clients.
4808 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4810 * Implemented SIGNOFF notify type handling in silc_server_notify
4813 * silc_server_remove_id now removes the client entry from all channels
4814 it has joined and thusly sends SIGNOFF notify type.
4816 * Rewrote the NAMES list generation in server by removing two excess
4817 loops. The lists are created now inside one loop.
4819 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * silc_server_remove_channel_user checks now also global list
4822 for channel and client.
4824 * silc_server_new_channel_user checks now both local and global
4825 list for channel and client. Fixed a bug in client id decoding.
4826 Used to decode wrong buffer.
4828 * silc_server_channel_message checks now both local and global
4829 list for channel entry.
4831 * Tested channel joining (hence JOIN) in router environment
4832 successfully. Tested with two routers, two servers and two
4835 * Tested channel message sending in router environment successfully.
4837 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Added silc_server_save_channel_key into server.[ch] to save the
4840 received channel key in Channel Key payload processing. It is
4841 also used in JOIN command reply handling.
4843 Equivalent function silc_client_save_channel_key added into
4844 client.[ch] into client library.
4846 * Changed JOIN command reply to send information whether the channel
4847 was created or not (is existing already) and the channel key
4848 payload. Changed protocol specs accordingly.
4850 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4851 the request was sent by ID and not by nickname. Crashed on
4854 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4857 now correctly save the received data.
4859 * silc_server_free_sock_user_data now notifies routers in the
4860 network about entities leaving the network.
4862 At the same time implemented functions silc_server_remove_id
4863 and silc_server_send_remove_id to receive and send REMOVE_ID
4864 packets. The packet is used to notify routers in the network
4865 about leaving entities. The ID removed will become invalid in
4868 * Added function silc_idlist_del_server into server. Removes and
4869 free's server entry from ID list.
4871 * silc_server_private_message function now checks, if we are router,
4872 that the destination ID really is valid ID, naturally.
4874 * In router when NEW_ID packet is received (for new client) the
4875 hash of the Client ID is saved in the ID Cache but the
4876 client->nickname is set to NULL, instead of putting the hash
4879 IDENTIFY command now also checks that client->nickname must be
4880 valid. If it is not if will request the data from the server who
4881 owns the client. Added new function
4882 silc_server_command_identify_check.
4884 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4885 to set the command to already allocated Command Payload.
4887 * Tested private message sending in router environment with two
4888 routers, two servers and two clients. Fixed minor bugs and now
4891 * Fixed segfault from client's NAMES command. Used to crash if
4894 * Forwarded packets must not be routed even if it is not destined
4895 to the receiver. Changed server code comply with this.
4897 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added `require_reverse_mapping' boolean value to ServerParams
4900 structure. If TRUE (not default) the server will require that
4901 the connecting host has fully qualified domain name.
4903 If the reverse mapping is not required and hostname could not be
4904 found the IP address is used as hostname.
4906 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Implemented version string checking to both client and server.
4909 The check is incomplete currently due to the abnormal version
4910 strings used in development version of SILC.
4912 * Changed all command functions in server to use the new
4915 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Changed char *data to unsigned char *data in ID Cache system to
4918 support binary data as ID Cache data. Changed code to support
4919 binary data in lib/silccore/idcache.c.
4921 * Renamed silc_server_packet_relay_command_reply to
4922 silc_server_command_reply as it is normal packet receiving
4923 function. Rewrote the function to accept command replys for
4924 servers and not only for clients.
4926 * Mark remote router always as registered server if we are connecting
4927 to it. Otherwise, commands sent by the router to us are ignored.
4929 * All ID List find routines now returns the ID Cache Entry pointer
4930 as well if requested.
4932 * WHOIS command works now in router environment, tested with two
4933 routers, two servers and two clients.
4935 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4936 in router environment (as it is almost equivalent to WHOIS) but
4937 hasn't been tested thoroughly. Added new functions:
4939 silc_server_command_identify_parse
4940 silc_server_command_identify_send_reply
4941 silc_server_command_identify_from_client
4942 silc_server_command_identify_from_server
4944 * Disabled route cache adding because adding two different ID's with
4945 same IP replaces the old cache entry thus giving wrong route.
4946 The entry->router->connection is always the fastest route anyway
4947 so route cache may not be needed. Of course, new routes maybe
4948 established after receiving the ID when the entry->router->connection
4949 might not be anymore the most optimal.
4951 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Add route cache for received ID for fast routing.
4955 * Added silc_server_packet_route to route received packet on router
4956 that is not destined to us.
4958 * Renamed silc_server_get_route to silc_server_route_get.
4960 * Added id_string and id_string_len fields into SilcServer to
4961 include encoded ServerID for fast comparing without excess
4962 encoding of the ID's.
4964 * Cleaned up WHOIS command on server side. Added following static
4967 silc_server_command_whois_parse
4968 silc_server_command_whois_check
4969 silc_server_command_whois_send_reply
4970 silc_server_command_whois_from_client
4971 silc_server_command_whois_from_server
4973 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4974 arguments in command replies. All command functions should be
4975 updated to use this macro.
4977 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Minor typo fixes on command reply handling on server.
4981 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Added silc_server_command_add_to_channel internal routine to add
4984 the client to the channel after router has created the channel and
4985 sent command reply to the server.
4987 * Added generic silc_server_send_command to send any command from
4990 * Use static buffer with ID rendering instead of duplicating data.
4992 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4994 * Fixed a channel user mode bug when joining to a channel server gave
4995 everybody channel founder rights, oops.
4997 * We mark ourselves as the router of the incoming server connection
4998 if we are router ourselves. This way we can check in some packet
4999 sending functions whether it is locally connected server. For
5000 incoming router connections we put NULL.
5002 * For router sending packets locally means now always sending the
5003 packet cell wide; to local clients and local servers. For normal
5004 server sending packet locally means sending it to only local
5007 * Fixed the JOIN command to really work in router environment. If the
5008 channel is created it is always created by the router. Router is
5009 also responsible of making the initial joining to the channel,
5010 sending JOIN notify to the sending server and distributing
5011 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5012 does not exist server doesn't do anything else but forward the
5013 command to the router which performs everything.
5015 * Added silc_server_send_channel_key function to send the Channel Key
5018 * Added silc_server_create_channel_key to create new channel key. The
5019 channel key is now re-generated everytime someone joins or leaves
5020 a channel, as protocol dictates. Note: channel->key_len is the
5023 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5026 packet_receive.[ch] to separate packet sending and receiving
5027 routines. The server.[ch] now includes everything else including
5028 actual packet processing (writing and reading data) and other
5031 Renamed silc_server_private_message_send_internal to
5032 silc_server_send_private_message. The routine is still though
5033 used only to relay private messages as server does not send
5034 private messages itself.
5036 Renamed silc_server_new_channel to silc_server_create_new_channel
5037 and added new function sicl_server_new_channel that handles the
5038 incoming New Channel packet. Added also new sending function
5039 silc_server_send_new_channel to send New Channel Payload.
5041 * Added new function silc_server_notify to process incoming notify
5042 packet to the server/router. Server may then relay the notify
5043 to clients if needed.
5045 * Added new function silc_server_new_channel_user to process incoming
5046 New Channel User packet. Router will redistribute the packet and
5047 send JOIN notify to its local clients and locally connected servers
5048 if needed. Normal server will send JOIN notify to its local client
5049 on same channel when received this packet. Added also corresponding
5050 sending function silc_server_send_new_channel_user to sent the
5053 * Added boolean route argument to send_notif_to_channel and
5054 packet_send_to_channel functions to attempt to route the packet
5055 if it is TRUE and send only locally if it is FALSE.
5057 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * silc_server_replace_id now broadcasts the received replace ID
5060 packet if it is not broadcast packet already. The router must
5061 broadcast to inform other routers about changed ID.
5063 * Added backpointer to server's router into SilcServer context in
5064 silcd/server_internal.h.
5066 * Fixed silc_server_packet_broadcast to send correct broadcast
5069 * The channel key is now distributed to the local client as soon
5070 as it is received from the router (in router environment) so that
5071 no other packet may be sent for the channel until client has
5074 * silc_server_remove_channel_user now broadcasts the received
5075 Remove Channel User packet if it is not broadcast packet already.
5076 The router must broadcast to inform other routers about removed
5079 * Added users field into SilcPacketContext that is a reference count
5080 of the context. One can increase the reference count by calling
5081 silc_packet_context_dup which is now changed to just increase the
5082 reference count instead of duplicating the data. The reference
5083 count is decresed by calling silc_packet_context_free that will
5084 free the data after the reference count hits zero.
5086 For now on the packet context and everything allocated into it
5087 (including the raw packet from network) must be freed by calling
5088 the new silc_packet_context_free function. Added also new function
5089 silc_packet_context_alloc that must be used now to allocate the
5090 context. This also means that if a routine is asynchronous from
5091 silc_[client/server]_packet_parse_type the packet context must
5092 be duplicated by calling silc_packet_context_dup. Otherwise it
5093 gets free'd after silc_[client/server]_packet_parse_type returns.
5094 Also, one must remember that if packet is duplicated then its
5095 reference count must be decresed by calling the free function as
5096 many times as it was duplicated.
5098 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5099 from both client and server.
5101 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Made joining to a channel working in router environment.
5105 * Cleaned up JOIN command on server side and create function
5106 silc_server_command_join_channel internal routine to make the
5109 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Changed silc_command_pending list to SilcDList. Also, added
5112 `ident' field to SilcServerCommandPending structure to identify
5113 the reply and to call correct callback.
5115 Added silc_server_command_pending_check function to replace the
5116 corresnponding macro. The silc_command_pending list is not
5119 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5120 to set identifier to previously allocated Command Payload. It
5121 is used to set identifier for command when resending Command
5124 * Added silc_command_payload_encode_payload to encode Command
5125 Payload buffer from SilcCommandPayload structure.
5127 * Added silc_argument_payload_encode_payload to encode Argument
5128 payload buffer from SilcArgumentPayload structure.
5130 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5132 * Changed WHOIS command to support router connection on server side.
5133 The whois request is always sent to router unless the server is
5134 standalone server. After server has received the reply from the
5135 router will it send the reply to the client.
5137 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5138 broadcast received broadcast packet. The function is used only
5139 by router. The broadcast packet is always sent to the router's
5142 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5143 render given ID to printable string, for log files for example.
5145 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Made basic router to router connections working. At least they
5148 can now connect to each other but nothing really works the way
5149 they are supposed - yet.
5151 * Added new initiator token to RouterConnection configuration
5152 file in silcd/serverconfig.[ch]. It is used to tell whether we
5153 are the initiator to the remote router or whether we'll expect
5154 the other end to connect.
5156 * Moved registering of listener task to silc_server_init, hence
5157 the server starts listenning as soon as it is run, even if it
5158 does not have connections to other routers. Let's see how well
5161 * Changed default connection retry timeouts for more suitable in
5164 * Removed cipher and such arguments from silc_idlist_add_client
5165 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5166 Added new function silc_idlist_add_data to add the keys and stuff
5169 * Added SilcIDListData structure and added it to SilcClientEntry
5170 and SilcServerEntry as their first field in the structure. This
5171 way we can explicitly cast the ID entries to the SilcIDListData
5172 structure and get common data for the entries. In past, we had
5173 to first check what type of connection it is and then cast it to
5174 correct ID entry type. Now, we can directly cast the opaque
5175 pointer to the SilcIDListData (no matter what ID entry it actually
5176 is) and get the data needed.
5178 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5181 in some circumstances even if threre were timeout tasks, though not
5182 IO tasks, but tasks anyway. Now fixed.
5184 * Defined SilcServerConnection structure to hold connection specific
5185 stuff about directly connected servers and routers. The definition
5186 is currently in silcd/server_internal.h. I thought about having
5187 a bit more important role fro this struct but for now it is used
5188 only when connecting to other server (or router actually).
5190 * Added connecting retry support in server when connecting to
5191 router(s). The retry feature implement exponential backoff
5192 algorithm. Also, added SilcServerParams structure to hold default
5193 parameters for server. For now, it include these retry settings
5194 and are hard coded. After server is moded to be as Silc Server
5195 Library this structure will be more important.
5197 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * Changed client librarys channel->clients table to SilcList and
5200 changed code accordingly.
5202 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Changed client's channel table to SilcList and changed code
5205 accordingly. Also changed SilcChannelClientEntry to include back-
5206 pointer to the channel so that client entry can use that structure
5207 as list as well and we have fast cross-reference to the channel.
5208 This change dramatically decreased the complexity of channel
5209 handling with client entry and vice versa (removed one extra
5210 loop when searching for channel entry from many functions).
5212 * Changed server->sim from table to SilcDList and changed code
5215 * NAMES command can now be used from user interface. It will show
5216 the user list on the channel, neatly.
5218 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5219 Code now saves realname of the user if it becomes available.
5221 * Renamed configure.in to configure.in.pre and made ./prepare
5222 script to automatically add correct version string to
5223 configure.in which it creates from configure.in.pre.
5225 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * NAMES command reply now shows users mode with the nickname when
5230 * Moved silc_client_ch[u]mode[_char] functions from
5231 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5232 place sucks, they are utility functions and should be in some
5235 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5237 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5240 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5244 * Added TRQ (efficient deque and list library) into lib/trq. This is
5245 a very good list library that is currently used in the SILC. Defined
5246 SilcList API over the library because I didn't like the API very
5247 much. See lib/trq/silclist.h for the API and examples of how to
5248 use the API. Fixed various places in the code to use the new
5249 SilcList API. The SilcList is meant for lists that has a structure
5250 already defined as a list. It is not suitable to add just some
5251 context to the list (in TRQ, the context is the list actually).
5253 So, I defined SilcDList that can be used for the purpose where
5254 predefined list structure does not exit. This can be used as
5255 such list. Now some context just can be added to the SilcDList.
5256 Currently this list is not used in the SILC just yet, though there
5257 are a lot places where this can replace dynamically allocated
5258 tables and I will fix these places, later, to use SilcDList.
5259 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5260 and use TRQ internally).
5262 Also fixed some annoying warning messages that the original TRQ
5263 code generated. Also minor changes to TRQ's Makefile.in.
5265 * Added support for querying by Client ID to both WHOIS and
5266 IDENTIFY commands into server, as required by the protocol.
5268 * Removed method function pointers from SilcBuffer structure. They
5269 weren't used to anything and just increased the context size for
5270 no good reason. This change also made silc_buffer_alloc and
5271 silc_buffer_free functions inline functions.
5273 * Disabled command flooding detection support until it's fixed so
5274 that it accepts commands in but does not execute them more than once
5277 * Added silc_net_localhost(), to return local hostname, into
5278 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5279 that must be initialized before calling silc_client_init.
5281 * Added new function: silc_server_send_notify_on_channels to send
5282 notify messages to all channels client has joined. It is assured
5283 that the message is sent only once per client.
5285 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5286 lib/silcutil/silcutil.[ch] as silc_format function. The new
5287 function is generic and is used by server as well, not only by
5288 the logging routines.
5290 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5291 the provided version string was not acceptable. Added new function:
5292 silc_ske_check_version into lib/silcske/silcske.h. The function
5293 must be implemented by the application (client or server) and it
5294 does not reside in the SKE library. The function checks the version
5295 string remote end sent.
5297 * Added back pointers (to opaque context and to SilcSocketConnection)
5298 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5300 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5301 duplicate packet context structure.
5303 * Changed `notify' client operation to send same arguments as client
5304 receives from server except for ID's. ID's are mapped to correct
5305 ID entry and that is returned. Also, if channel entry is not sent
5306 by server but the notify is for channel the channel entry is sent
5307 to application (otherwise application doesn't know that it is for
5308 channel (library gets it from packet's Destination ID)).
5310 * Added silc_client_remove_from_channels into client library to
5311 remove a client from all channels it has joined to. Used when
5312 received SIGNOFF notify from server. Added also new function
5313 silc_client_replace_from_channels to replace old ID entry with
5314 new ID entry on all channels. Used when received NICK_CHANGE
5317 * Fixed ID Cache list handling in silc_idlist_get_client in
5318 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5319 to get (or query) client by ID.
5321 * Updated TODO list.
5323 * Added connection authentication status message defined by the
5324 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5325 support for these into the code in client and server side.
5327 * Added generic function silc_client_send_command to send any command
5328 with variable argument list. Application should use this function
5329 to send commands if the command functions provided by the library
5330 does not suite for the application's user interface needs.
5332 * Added new `failure' client operation. Application is notified about
5333 received failure packet if client is executing a protocol. In this
5334 case the protocol's execution has failed.
5336 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5337 is required by the protocol.
5339 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5340 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5343 * Added status flag to SilcSKE object to indicate realtime status
5344 of the SKE protocol.
5346 * Application receives now exactly same command reply arguments as
5347 the library receives from server. However, if ID is received the
5348 corresponding ID entry is returned to the application (eg. Client
5349 ID is mapped to correct SilcClientEntry entry and that is returned).
5350 Changed command_reply client operation due to this change.
5352 * Changed all ID's in commands and in command replys as ID Payloads.
5353 Change affected both client and server side codes.
5355 All ID's sent in SILC network (with execption of ID's in SILC
5356 Packet header) are sent in ID Payload to support variable length
5359 * Server now notifies nick changes and notifies all clients on
5360 the channels about the new nickname (about the new Client ID,
5363 * Implemented CMODE command to change channel modes. Supports all
5364 channel modes defined by the protocol specs except ban and invite
5365 lists. (Also, private channel key mode is supported but support for
5366 setting private channel key in client is missing, thus, this mode
5367 has no effect on client side (except that server requires that the
5368 client uses private channel key and normal channel traffic does not
5371 Also, invite mode works per se, but INVITE command does not work
5372 yet correctly, so you can set channel as invite only channel but
5373 inviting clients to the channel does not work (it is yet to be
5374 thought what's the best way to do it).
5376 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5377 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5378 Implemented CUMODE command to change user's mode on the channel.
5379 Supports all modes defined by the protocol specs.
5381 * Added NAMES command reply to return users modes on the channel.
5383 * Removed unnecessary and slow ciphers from lib/silccrypt.
5385 * Set SO_KEEPALIVE option to connection sockets by default.
5387 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5389 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5390 redefined the Notify Payload into protocol specs.
5392 * Added silc_id_payload_parse_id to get ID directly from raw
5395 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5398 accept searching by Client ID as well.
5400 * Added support for LEAVE and SIGNOFF notify types in client library.
5402 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5403 to parse ID Payload from raw data.
5405 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Added flags parameter into silc_ske_assemble_security_properties
5408 function in lib/silcske/silcske.[ch].
5410 * Changed notify client operation to fit better for notify messages
5411 sent by server. The notify payload received from server is now
5412 passed to the application (after parsing it to SilcNotifyPayload).
5413 It is application's responsibility to retrieve the arguments
5414 from the payload and show the message the way it wants. The message
5415 sent by server is implementation specific.
5417 * Changed public keys to comply with the protocol specification.
5418 Old public keys are not supported anymore and are not compatible.
5420 * Removed nickname from Channel Payload as the latest draft removed
5421 it. The client must resolve the nickname from the NAMES command
5422 reply received when it joined the channel.
5424 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5426 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Fixed some errors in protocol specification drafts.
5430 * Created lib/silccore/silcnotify.c to implement Notify Payload
5431 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5432 generic payloads described by protocol specifications. The file
5433 includes implementations for ID Payload and Argument Payload.
5435 * Changed Command Payload implementation to use the new Argument
5436 Payload. Changed command_xxxx_payload to command_payload_xxxx
5437 to comply with SILC coding conventions.
5439 * Added suppport for Argument Payload handling in Notify Payload
5440 implementation as protocol requires it. Added the new support
5441 into server and client lib as well.
5443 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Added support for multiple nicknames on same channel. [n] is
5446 added locally to the nickname if there are more than one same
5447 nicknames on the channel.
5449 * Server now sends all nicknames that matched WHOIS request.
5450 Client also shows the list received from server.
5452 * Added TOPIC command to client side. User can now set and show
5453 current topic on channel.
5455 * Added MOTD command to client and server. Also, server sends the
5456 motd when client connects to the server.
5458 * Changed version strings to comply ISO 8601.
5460 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Fixed protocol error handling in client library. It should now
5463 cope even if the SKE fails for some reason.
5465 * Made new protocol specification drafts for submitting to IETF.
5467 * Implemented TOPIC command to server in silcd/command.c.
5469 * Added two new notify types into lib/silccore/silcnotify.h:
5470 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5471 notify nickname change and topic setting/change on a channel.
5473 * API change of command_reply operation in client library. The
5474 application gets now the status type received from server as well.
5476 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5480 * Cras fixed and optimized the packet handling even further and
5481 it should work now. Minor change to the prototype of function
5482 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5484 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5486 * Added new function into lib/silcutil/silcschedule.[ch]:
5487 silc_schedule_with_fd to select() a specified fd. The function
5488 returns after timeout expires or data arrives or goes. The
5489 function is used by packet routines to wait that all data is
5490 received from network.
5492 * Fixed data reading from network in lib/silccore/silcpacket.c.
5493 The code now assures that all data is read from the fd and then
5494 continues packet processing. This was a bug fix since the code
5495 used to drop some data in some circumstances.
5497 * Added new function into lib/silcclient/client.[ch]:
5498 silc_client_start_key_exchange to start key exchange after
5499 connection has been established to server. The code internally
5500 now uses this funtion but its main purpose was to provide it
5501 for applications that perform their own connecting. After
5502 application has created a connection it merely calls this
5503 function to start the key exchange between client and server.
5504 The library takes care of everything else after that.
5506 Updated also lib/silcclient/README to explain the usage of
5509 * Do not send to application information that connection has
5510 been established. Application gets notified it by connect
5513 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Applied cras's patch to add silc_schedule_one function. The
5516 function runs scheduler once and returns.
5518 * Fixed the scheduler after cras messed it up. The timeout
5519 handling works now as it's supposed to work.
5521 * Added into lib/silccore/ silcnotify.h to include notify
5522 message types support. Changed silc_server_send_notify*
5523 functions, in server.[ch], to support those new notify types.
5524 Added the support for the notify types into client library,
5525 as well. Added new notify client operation into ops.h in
5528 * Changed silc_server_packet_send_to_channel to send normal
5529 packets instead of just channel message packets. The function
5530 is now used to send the notify packets to channels. It is not
5531 used to send channel message packets anymore, as server never
5534 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5535 va_arg()s as it seems to require it nowadays. I guess, if SILC
5536 is compiled with older va_arg() the new code should work anyway.
5538 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Splitted core library. Core library (lib/silccore) includes
5541 now only SILC protocol specific core (and common) components.
5542 Created new utility library (lib/silcutil) that includes more
5543 generic purpose stuff. The stuff for util library was taken
5544 from the old core library. This was minor and easy split.
5546 * Created SILC Client Library (lib/silcclient) that includes
5547 implementation of the SILC client without user interface. This
5548 was major move from silc/ directory. The code has been changed
5549 so that it is transparent towards the user interface. The
5550 silc/ directory includes now the same user interface as before
5551 and it uses the new client library. Read lib/silcclient/README.
5552 Basicly, the client library performs everything else related
5553 to SILC except user interface handling. Also, configuration
5554 files are considered to be part of user interface and library
5555 does not handle them.
5557 This change also changed a lot of structures, function naming etc.
5558 Most important change was that SilcClientWindow object was
5559 renamed to SilcClientConnection in the client library. Created
5560 also new file lib/silcclient/ops.h. Also added new files
5561 silc/local_command.[ch] and silc/client_ops.[ch].
5563 All these changes were made to make it easier for user interface
5564 designers to create what ever user interface for the SILC client
5567 It is also expected that the server will be moved to lib
5568 directory as well and SILC Server Library will be created;
5569 sometimes in the future.
5571 * Removed Local commands from lib/silccore/silccommand.h as
5572 they are application specific and new client library does not
5573 handle any of those anymore.
5575 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5576 old client implementation in silc/.
5578 * Added support for callback functions in SILC_LOG_* macros.
5579 Application can now set its own callbacks that will be called
5580 instead of using the default functions that will always print
5581 the debug messages to stderr (or stdout). Also, debugging can
5582 now be disabled by setting silc_debug to FALSE and re-enabled by
5583 setting it to TRUE. Note, that logging will still work even
5584 if debugging is disabled.
5586 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5587 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5588 silc_log_reset_debug_callbacks.
5590 * To enable debugging in silc client one must give now -d
5591 option on command line.
5593 * Changed silc_schedule_init to automatically allocate task queues
5594 if they are not allocated before calling it.
5596 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Added GMP 3.1 into math library.
5600 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5603 a channel in SILC network. The packet is used by servers and
5604 routers to notify other routers that user has left a channel.
5605 This little feature was missing until now. Added the feature
5606 to protocol specification as well.
5608 Added functions: silc_server_send_remove_channel_user and
5609 silc_server_remove_channel_user into server.[ch].
5611 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5612 lib/silccore/silcpacket.h. However, they are not implemented
5615 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Fixed joining to a channel and sending channel messages
5618 between server and router. The channel message sending should
5619 now work inside a cell.
5621 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Fixed the private message sending between server and router.
5624 The private message sending should now work inside a cell.
5626 * Added silc_server_replace_id into server.[ch] to replace
5627 existing ID in the SILC network.
5629 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5630 and silc_idlist_replace_server_id into idlist.[ch] in server.
5632 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Fixed the server to server connections. Server can again now
5635 connect to router. Router to router connections probably does
5638 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Added dynamic protocol registering support. Now protocols can
5641 registered and unregistered on the fly. Patch by cras.
5643 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added lib/contrib directory to hold routines that some platforms
5646 don't have but are needed by SILC.
5648 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5649 into lin/contrib to provide getopt() and getopt_long() for
5650 those who don't have it.
5652 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Added AWAY command to client. When away message is set and
5655 client receives a private message packet the client automatically
5656 replies to the sender with the away message.
5658 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5659 bug seemed to be the cause of recent problems when compiling
5662 * Added version detection support to SKE protocol specification
5663 and added the new changes to the SKE implementation as well.
5664 There were other minor changes in the SKE protocol as well.
5666 Many changes in lib/silcske/silcske.[ch] and in
5667 lib/silcske/payload.[ch].
5669 * Added ^U functionality, clear input line. Patch from cras.
5671 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Mainly small bugfixes on core library. Fixed some debugging
5674 logging and buffer overflow in silclog.c.
5676 * Updated config.sub and config.guess on the distribution tree.
5678 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Added command lagging support in server. Client may execute
5681 commands now only once in two seconds.
5683 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Optimized packet reception. MAC computation and checking is now
5686 also more optimized. A lot previously duplicated code is now
5687 used as generic by both client and server.
5689 * Fixed key pair generation in clientutil.c
5691 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Added into lib/silccore/silcbufutil.[ch] new function;
5694 silc_buffer_realloc.
5696 * Moved generic packet sending/encryption functions to
5697 lib/silccore/silcpacket.[ch] from client and server. Some
5698 rewriting of the functions.
5700 * Moved all generic packet reception/decryption functions to
5701 lib/silccore/silcpacket.[ch] from client and server. The
5702 packet processing is now much cleaner in both client and server.
5703 These were major changes in both client and server.
5705 * Created many common functions in server to do packet sending.
5706 Previously code were duplicated a lot, this has been removed
5709 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Rewrote major parts of the ID cache system. Don't know
5712 whether it is better now or not but at least the API is more
5715 * Major rewrite on ID cache stuff on client because of the ID
5716 cache API changes. Added idlist.c to client.
5718 * Also major rewrite on ID cache stuff on server as well.
5719 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5720 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5721 in hand, instead they are all put into the ID cache system now.
5722 All server_idlist_* routines uses ID cache now instead of
5723 traversing its own lists (those lists does not exist anymore).
5724 SilcIDList though still exists. Also, SilcXXXEntry's are
5727 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5729 * Finally made the SKE implementation compliant to the protocol
5730 specification. All mp integers are now binary encoded as
5731 opposed being HEX encoded.
5733 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5736 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5737 functions: silc_[encode/decode]_pem. Also added function
5738 silc_encode_pem_file to PEM encode with newlines ('\n') for
5741 * SILC public keys are now encoded either PEM or binary. Same
5742 option is for private keys as well. By default private keys
5743 are binary encoded and public keys PEM encoded. Silly HEX
5744 encoding were removed.
5746 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5747 function to create fingerprints.
5749 * Fixed a bug in SHA1; does not change the original data anymore.
5751 * Partly implemented INFO command on client and server side.
5752 Fixed CLEAR command. Changes to SERVER command; show current
5753 server(s) when giving command without arguments. Added
5754 VERSION command to client.
5756 * Added check to server that unregistered connections cannot
5757 execute commands (unless it is specificly allowed).
5759 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Fixed screen refresh.
5763 * Fixed channel joining bug from client. On some circumstances
5764 client tried to join to a channel it had already joined.
5766 * Added public key verification process into client's protocol.c.
5767 The client now verifies the public key from user and saves
5768 it into ~./silc/serverkeys/ directory.
5770 Added into: clientutil.[ch]: silc_client_verify_server_key.
5772 * Changed SKE protocol's silc_ske_initiator_finish function
5773 to accept callback function that verifies the received public
5774 key. Removed old silc_ske_verify_public_key function.
5776 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5779 silc_pkcs_private_key[_data]_set.
5781 * Made the password and public authentication more cleaner in
5782 server's protocol.c.
5784 * Removed historic and obsolete protocol `channel_auth' from
5785 both client and server.
5787 * Removed wrong way of sending command status messages from
5788 server to client in server's command.c. The old way violated
5789 protocol specification.
5791 Changes to silccore/silccommand.[ch]: removed
5792 silc_command_encode_status_payload -> not needed anymore,
5793 changed silc_command_encode_payload_va to accept extra
5794 argument on variable argument list. The argument type must
5795 now be provided to the function. Also, added new function:
5796 silc_command_encode_reply_payload_va which is same as
5797 normal command_encode_payload_va except command status type
5798 is provided as extra argument.
5800 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Added ~./silc directory handling. The directory includes the
5803 public and private keys for the client.
5805 Added silc_client_check_silc_dir, silc_client_create_identifier
5806 and silc_client_load_keys.
5808 * Implemented SILC protocol compliant public key. Added public
5809 and private key saving to and loading from files.
5811 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5812 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5813 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5814 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5815 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5817 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5818 silc_pkcs_load_[public/private]_key.
5820 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Added silc_server_get_route (route.[ch]) to get connection
5823 data for the fastest route for given ID.
5825 * Implemented INVITE command on client and server. The command
5826 were re-defined in the SILC Protocol Specification and the
5827 implementation now complies with the specification.
5829 * Implemented PING command on client and server.
5831 * Implemented NAMES command on client and server. The server side
5832 supports currently only normal server not router server yet.
5833 Some changes to NAMES definition in SILC protocol specification.
5835 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Implemented LEAVE command on client and server.
5839 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5840 again. This change was made to the protocol as well. Server
5841 should not violate the protocol specification anymore.
5843 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5846 was tested. SOCKS4 was not but should work anyway.
