57 during SERVER_SIGNOFF, but invalidate it. This way we
58 preserve the WHOWAS info for the client. Affected file
61 * Fixed SERVER_SIGNOFF notify handling in the server. The
62 server is now able to process incoming SERVER_SIGNOFF notify
63 for a server that it doesn't even know about. It will remove
64 the clients provided in the notify. Affected file
65 silcd/packet_receive.c.
67 * Check for partial packet in data queue after every packet that

108 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
110 * Assure that silc_client_notify_by_server_resolve does not
111 resolve the client information multiple times. If it cannot
112 be found by the first it cannot be found at all. Affected
113 file lib/silcclient/client_notify.c.
115 * Fixed WHOWAS command reply calling. Affected file
116 lib/silcclient/command_reply.c.
118 * Removed all references to silc_idlist_get_client from the
119 Irssi SILC client since that call is internal call used by
120 the library. The Irssi SILC client will use now client
121 retrieval functions found in silcapi.h.
123 * Fixed a bug in resolving nickname info before sending
124 private message. It used freed memory. Affected file
125 irssi/src/silc/core/silc-servers.c.

151 in packet queue that we are not able to process without first
152 processing packets before them. Affected file silcd/server,
153 lib/silcclient/client.c.
155 * SilcPacketParserCallback now returns TRUE or FALSE to indicate

240 * Redefined the SILC packet header to include the padding
241 length. Affected file lib/silccore/silcpacket.[ch].
243 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
244 length for maximum padding up to 128 bytes). Affected
245 file lib/silccore/silcpacket.h.
247 * Removed all backwards support for old 0.5.x MAC thingies.
248 The SILC packet header change makes it impossible to be
249 backwards compatible.

252 protocol. This is to assure that all routers has connected
253 to the primary router. Affected file silcd/server_backup.c.
255 * Changed the RNG to take the first IV from random data. It
256 used to take it from zero actually. Changed the RNG also
257 to use /dev/urandom during session. /dev/random is used
258 in initialization. Affected file lib/silccrypt/silcrng.[ch].
260 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Changed the SILC packet header to have the first two bytes
263 (the packet length) encrypted. Affected files aroung the
264 code tree, lib/silccore/silcpacket.[ch]. Removed the
265 SilcPacketCheckDecrypt callback. It is not needed anymore
266 since the silc_packet_receive_process will determine now
267 whether the packet is normal or special.
269 * Implemented the unidirectional MAC keys. Affected files
270 lib/silcske/silcske.c, silcd/protocol.c and
271 lib/silcclient/protocol.c.
273 * Implemented the packet sequence number to the MAC computation.
274 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
275 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
276 lib/silcclient/protocol.c.
278 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
280 * Allow backup router to announce servers. All servers
281 announced by backup router are added to the global list
282 automatically. Update hte server's socket to our primary
283 router also when backup router announces a server.
284 Affected file silcd/packet_receive.c.
286 * Do not update the client->router in the function
287 silc_server_udpate_clients_by_server if the client is on
288 global list. We might fail to find any specific server
289 for locally connected clients and local cell clients. They
290 should still use the `from' and not `to' as client->router.
291 This fixes backup router resuming protocol. Affected file
294 * Decrease channel statistics count only if the channel
295 deletion worked. Affected files are silcd/server.c and
298 * Added silc_server_update_servers_by_server to update origin
299 of all server entries. Used during backup router protocol.
300 Affected files silcd/server_util.[ch], silcd/server.c. and
301 silcd/backup_router.c.
303 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
304 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
305 silc_hmac_get_hash and silc_hmac_get_name. Affected file
306 lib/silccrypt/silchmac.c.
308 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
310 * Assure that router cannot reroute the same channel message
311 to the sender. Affected file silcd/packet_receive.c.
313 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
315 * Made better checks that the channel message is not sent
316 to the router it came from. Affected file is
317 silcd/packet_send.c. Fixed memory leak too.

326 router environment. Affected file silcd/server_backup.c.
328 * Route packet only to one router in the function
329 silc_server_packet_send_to_channel. Affected file is
332 * Fixed silc_server_send_notify_dest to set the broadcast
333 flag. Fixed the silc_server_send_notify_topic to actually
334 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
335 Affected file silcd/packet_send.c.
337 * Changed the SFTP Filesystem interface. Changed the
338 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
339 the filesystem operation function. The SilcSFTPFilesystem
340 is now a context that is allocated by all filesystem allocation
341 functions and it already includes the operations structure
342 and filesystem specific context. It is given as argument
343 now to the silc_sftp_server_start. This made the interface
344 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
345 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
347 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
349 * Changed the backup router adding and getting interfaces
350 in the server. The router that will be replaced by the
351 specified backup router is now sent as argument. Affected
352 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
355 * Added silc_net_addr2bin_ne to return the binary form of
356 the IP address in network byte order. Affected files
357 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
359 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

386 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
389 * Implemented the backup resuming protocol that is used to
390 resume the primary router position in the cell after the
391 primary router comes back online. Affected files
392 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
393 and silcd/server_util.[ch].

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

412 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
413 in the server to indicate disabled entry. All data read
414 from the connection will be ignored and no data is sent
415 for entry that is disabled. Affected files are
416 silcd/idlist.h, silcd/server.c.
418 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
420 * Created SFTP client and server test programs in the
421 lib/silcsftp/tests directory.
423 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
425 * Implemented memory filesystem (virtual filesystem) for
426 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
429 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Implemented the SFTP (SSH File Transfer Protocol) to the
432 lib/silcsftp. It includes SFTP client and SFTP server
435 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
437 * Moved lib/silccore/silcprotocol.[ch] to the
438 lib/silcutil library.
440 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
441 take variable argument list pointer as argument. Affected
442 file lib/silcutil/silcbuffmt.[ch].
444 * Added silc_buffer_set function that is used to set data
445 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
446 Affected file lib/silcutil/silcbuffer.h.
448 * Changed various routines in the core library to use the new
449 silc_buffer_set instead of allocating new buffer only for
452 * Added 64-bit value formatting and unformatting support to the
453 silc_buffer_[un]format routines. Affected file is
454 lib/silcutil/silcbuffmt.[ch].
456 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
457 to includes/bitmove.h.
459 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
461 * Fixed channel user mode saving in client library. Affected
462 file lib/silcclient/command[_reply].c.
464 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
466 * Defined the file transfer to the SILC Protocol. Added
467 new packet type SILC_PACKET_FTP and defined File Transfer
468 Payload. The mandatory file transfer protocol is SFTP
469 (SSH File Transfer Protocol). Affected file in addition
470 of the internet draft is lib/silccore/silcpacket.h.
472 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
473 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
474 is used as part of backup router protocol when the primary
475 router of the cell is back online and wishes to resume
476 the position as primary router.
478 * Redefined the MAC generation keys in the protocol. The
479 same key is not used anymore in both direction. Both
480 direction will now use different keys for sending and
481 receiving. This fixes a potential security flaw. This
482 change causes incompatibilities in the protocol.
484 * Redefined also the MAC computation from the packet.
485 An packet sequence number is now added to the MAC
486 computation. This prevents possible replay attacks against
487 the protocol. This change too causes incompatibilities
490 Added `sequence' field to the SilcPacketContext to hold
491 the current sequence number for the packet.
493 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Added `created' field to the SilcIDListData in the file
496 silcd/idlist.h to indicate the time when the entry was
499 * Added `created' field to the SilcChannelEntry too. Affected
502 * Added `creation_time' aguments to all the announcement functions
503 in the server. If it is provided then only the entries that
504 was created after the provided time frame are actually
505 announced. Affected file silcd/server.[ch].
507 * The protocol says that the Channel ID's IP address must be
508 based on the router's IP address. Added check for this in
509 the silc_server_new_channel when processing incoming New Channel
510 Payload. Affected file silcd/packet_receive.c.
512 * Print out the correct version with --version in SILC client.
513 Affected file irssi/src/silc/core/silc-core.c.
515 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

518 entry always, not just when the command is coming from client.
519 Affected file silcd/command.c.
521 * Added new function silc_server_packet_queue_purge to purge the
522 outgoing data queue to the network. After the function returns
523 it is guaranteed that the outgoing packet queue is empty.
524 Affected file silcd/packet_send.[ch].
526 * Purge the outgoing packet queue in the rekey protocol's final
527 callback to assure that all rekey packets go to the network
528 before quitting the protocol. Affected file silcd/server.c.
530 * Added silc_client_packet_queue_parse as similar function as
531 in server to the client library. The affected file is
532 lib/silcclient/client.c.
534 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Splitted silcd/server.c and created silcd/server_util.[ch]
537 for utility functions.
539 * Added new socket flag SILC_SF_DISABLED to indicate that the
540 connection is open but nothing can be sent to or received from
541 the connection. Affected file lib/silcutil/silsockconn.[ch].
542 The checking for disabled socket is checked in the low level
543 silc_socket_write and silc_socket_read functions.
545 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
547 * Allow only nicknames and channel names that fits into the
548 7-bit unsigned char ASCII set. Affected file silcd/command.c.
550 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
552 * When processing JOIN command reply in server check that if
553 the channel exists in our global list we'll move it the local
554 list. Affected file silcd/command_reply.c.
556 * Fixed the check whether client is joined on the channel already
557 in JOIN command. Affected file lib/silcclient/command.c.
559 * Fixed the JOIN command reply to check whether the channel
560 already exists. Affected file lib/silcclient/command_reply.c.
562 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
564 * Added silc_ske_status_string to map the SKE error numbers
565 to readable strings. The affected files are
566 lib/silcske/silcske[_status].[ch].
568 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
570 * Do not show the private channels on the WHOIS channel list
571 as it is not allowed by the protocol. The affected file is
574 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
576 * Assure that the packet length digged from the actual packet
577 is something sensible in the silc_packet_decrypt_rest_special
578 in lib/silccrypt/silcpacket.c.
580 * Free and NULL the allocated pointer in silc_hmac_alloc if
581 the HMAC allocation fails. The affected file is
582 lib/silccrypt/silchmac.c.
584 * Print the selected security properties to the log files in
585 the server. Affected file silcd/protocol.c.
587 * Add SKE's reference counter even if calling the completion
588 callback manually. Otherwise it goes negative, although it
589 does not cause any problems. The affected file is
590 lib/silcske/silcske.c.
592 * Remove the client entry with short timeout after giving the
593 KILL command. Affected file lib/silcclient/command.c.
595 * Fixed to send error reply in WHOIS and IDENTIFY commands in
596 case all found clients are already disconnected (WHOWAS would
597 found them) in the server. Affected file silcd/command.c.
599 * Update the last_receive (time of last data received) to be
600 updated only when received private or channel message so that
601 the idle time showed in WHOIS makes more sense.
603 * Added boolean field `valid' in to the SilcClientEntry in the
604 client library to indicate whether the entry is valid or not.
605 This fixes the nickname change bug on channel when changing
606 the nickname to be same than the old (like nick to Nick) the
607 nickname formatter doesn't set the new nick anymore to Nick@host.
608 Affected file lib/silcclient/idlist.[ch].
610 * Now actually fixed the nickname changing on disconnection.
611 Added new function silc_change_nick to the Irssi SILC Client.
612 Affected file irssi/src/silc/core/client_ops.c,
613 irssi/src/silc/core/silc-nicklist.[ch].
615 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
617 * Check that the public key exists in the GETKEY command before
618 trying to encode it. Affected file silcd/command.c.
620 * Print some notifications on received public keys with GETKEY
621 command in the Irssi SILC Client. Affected files are
622 irssi/src/fe-common/silc/module-formats.[ch],
623 irssi/src/silc/core/client_ops.c.
625 * Use IDENTIFY command to resolve the server information in the
626 GETKEY command instead of INFO command. Affected file
627 lib/silcclient/command.c.
629 * All command reply functions in the client library now calls
630 the pending command reply callbacks even if an error has
631 occurred. The server has done this a long time and now it was
632 time to move the client library to this as well. Now all
633 errors can be delivered back to the pending command reply
634 callbacks if necessary. Affected files are
635 lib/silcclient/command[_reply].[ch].
637 * Change the nickname on disconnection back to the username
638 because in reconnect the server will enforce it to it anyway.
639 Affected file irssi/src/silc/core/silc-servers.c.
641 * Fixed a config file parsing bug in the Irssi SILC client.
642 Affected file irssi/src/silc/core/clientconfig.c.
644 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
646 * When printing the channel mode on JOIN, verify that the
647 channel key and channel's HMAC are valid. Affected file
648 irssi/src/silc/core/client_ops.c.
650 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
652 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
653 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
654 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
656 * Removed channel key rekey task deleting from the function
657 silc_server_save_channel_key. Affected file silcd/server.c.
658 Added explicit timeout task context instead that is used to
659 delete the task if we are registering a new task before the
660 new task has elapsed.
662 * When channel key rekey occurs the client library now saves
663 the old channel key for a short period of time (10 seconds) and
664 is able to use it in case some is still sending channel
665 messages encrypted with the old key after the rekey. Affected
666 file lib/silcclient/[idlist.h|client_channel.c].
668 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
670 * Added check to the silc_server_new_id_real to not accept
671 new ID if it is the sender's own ID. Affected file is
672 silcd/packet_receive.c.
674 * Assure that we do not announce ourself or the one we've
675 sending our announcements when we're router and are announcing
676 servers to our primary router. Affected file silcd/server.c.
678 * Fixed silc_server_command_identify_check_client to assemble
679 correct WHOIS packet. It send corrupted WHOIS packet and
680 caused problem with router to router connections. Affected
681 file silcd/command.c.
683 Fixed also silc_server_command_whois_check the same way
684 as for the IDENTIFY command.
686 * Added new SilcIDListStatus to the server in the SilcIDListData
687 structure. The status now includes the current status of
688 the entry (like registered, resolved etc.). Affected file
689 silcd/idlist.[ch]. Defined a bunch of different status types
690 as well. This replaced the old boolean registered field as well.
692 Added resolve_cmd_ident field to the SilcClientEntry structure
693 too so that if the entry is for example being resolved so
694 another command may attach to the same pending command reply
695 without requiring to resolve the same entry again. This concept
696 should optimize the WHOIS and the IDENTIFY resolving under
697 heavy load by taking away unnecessary resolving for entries
698 that are being resolved already.
700 Added support for adding multiple pending commands for one
701 command idenfier. Affected file silcd/command[_reply].[ch].
703 * Fixed WHOIS and IDENTIFY save to remove the cache entry
704 before deleting the data. Otherwise the hash table will have
705 freed data in comparison functions. Affected file is
706 silcd/command_reply.c.
708 * Fixed silc_idlist_replace_client_id to add the new entry to
709 the cache with NULL nickname. Otherwise there will be invalid
710 memory as the nickname after the nickname is freed. Affected
711 file silcd/packet_receive.c.
713 * Fixed the silc_idlist_get_clients_by_hash. The entries was
714 saved into wrong slots because the previous number of entries
715 was not taken into account. Affected file silcd/idlist.c.
716 Fixed same thing in silc_idlist_get_clients_by_nickname too.
718 * If we are router and we receive JOIN notify to a channel that
719 does not have any users then notified client is marked as the
720 channel founder, as it is it. The affected file is
721 silcd/packet_receive.c
723 * Added to the extended hash table API's table_del_*ext functions
724 the destructor as argument too, so that the caller can decide
725 which destructor to use or whether to use destructor at all.
726 Affected file lib/silcutil/silchashtable.[ch].
728 * Fixed ID Cache purging. It actually deleted the entries from
729 the hash table after the data was freed. The hash table ended
730 up comparing freed memory. The affected file is
731 lib/silccore/silcidcache.c.
733 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
735 * Fixed Irssi SILC client's KILL command's HELP syntax.
737 * The USERS command now resolves the detailed user information
738 if the userinfo field is missing. Affected file is
739 lib/silcclient/command_reply.c.
741 * Do not print error in silc_file_read if the read file does
742 not exist. Just silently return NULL. Affected file is
743 lib/silcutil/silcutil.c.
745 * Fixed the silc_log_output to not wine about NULL filename
746 and to not create some bogus " " filename. Affected file is
747 lib/silcutil/silclog.c.
749 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
751 * Fixed various printing bugs on the user interface in the
752 Irssi SILC Client. Minor changes that were forgotten from
755 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
757 * Fixed the configure.in.pre and the compilation and distribution
758 environment to support the new autoconf 2.52. That version is
759 now required to compile the CVS trunk.
761 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
763 * Renamed function silc_parse_nickname to silc_parse_userfqdn
764 to generally parse user@fqdn format strings. Affected file
765 lib/silcutil/silcutil.c.
767 * Added nickname_format and nickname_force_format fields to the
768 SilcClientParams structure. The first one defines the format
769 for the nicknames that the library will enforce if the receives
770 multiple same nicknames. The second one is boolean value and
771 can be used to force the library to always enforce the format
772 to the nicknames regardles whether there are multiple nicknames
773 or not. This configurable formatting was employed to flexibly
774 support accessing multiple nicknames from the user interface.
775 The userinterface can now set the nicknames to what ever format
776 they prefer. Affected file lib/silcclient/silcapi.h.
778 Added function silc_client_nickname_format to the file
779 lib/silcclient/idlist.c. It performs the nickname formatting.
781 Added new field `hostname´ to the SilcClientEntry context.
782 It holds the hostname of the client. Affected file is
783 lib/silcclient/idlist.h.
785 * Irssi SILC Client sets the nicknames in nick@hostn format.
786 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
787 irssi/src/silc/core/silc-core.c.
789 The WHOIS printing now also shows both the real nickname and
790 the formatted nickname so that user knows how to access the
791 user if there are multiple same nicknames cached. Affected
792 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
793 printing formatting too to take the hostname now as a separate
794 argument. The Affected file is
795 irssi/src/fe-common/silc/modules-formats.[ch].
797 * Changed the silc_client_get_clients_local to accept the formatted
798 nickname as argument. It accepts the real nickname too but the
799 formatted nickname can be used to find the true entry from
800 multiple entries. Affected file lib/silcclient/silcapi.h and
801 lib/silcclient/idlist.c.
803 * Added nickname_format_parse field to the SilcClientParams.
804 It is a callback function provided by the application to parse
805 the nickname out of the formatted nickname string. The library
806 calls it to get the nickname from the formatted string. Since
807 the application generally knows better the format of the nickname
808 string it parses it instead of the library, even though library
809 encodes the formatted string. If the callback function is not
810 provided then the library will use the string as is. The
811 affected file is lib/silcclient/silcapi.h.
813 * All the nickname strings passed to the client library in
814 commands are now expected to be formatted nickname strings.
815 If the command does not support the formatted nickname string
816 it will assume that the sent string is the actual nickname.
817 Affected file lib/silcclient/command.c.
819 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Added public key authentication support to OPER and SILCOPER
822 commands in the client library. Affected file is
823 lib/silcclient/command.c.
825 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Changed the get_auth_methdod client operation to be asynchronous.
828 It can be async if the application resolves the authentication
829 method from the server during the negotiation. Added new
830 SilcGetAuthMeth completion callback that the application will
831 call after resolving the authentication method.
833 Added function silc_client_request_authentication_method that
834 the application can use to resolve the authentication method
835 from the server. Added also SilcConnectionAuthRequest callback
836 that the library will call after the server has replied. The
837 application can call this function if it does not know the
838 current authentication method.
840 Affected files are lib/silcclient/client.c and
841 lib/silcclient/silcapi.h.
843 * The Irssi SILC client now automatically resolves the authentication
844 method incase any configuration information is not present (and
845 currently there never is). The affected file is
846 irssi/src/silc/core/client_ops.c.
848 * Fixed public key authentication from the client library.
849 Affected file lib/silcclient/protocol.c. Changed also the
850 protocol specification about the public key authentication in
851 the connection authentication protocol. The actual data to be
852 signed is now computed with a hash function before signing.
854 * Fixed the public key authentication from the server as well.
855 Affected file silcd/protocol.c.
857 * Removed the mlock()'s from the memory allocation routines.
858 Affected file lib/silcutil/silcmemory.c. The ./configure does
859 not check anymore for the mlock(). Affected file is
862 * Fixed USERS command in server to allow the execution of the
863 command for private and secret channels if the client sending
864 the command is on the channel. Affected file silcd/command.c.
866 * Fixed silc_client_get_clients_local to return the clients
867 count correctly. It could return wrong value. Affected file
868 lib/silcclient/idlist.c.
870 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
872 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
873 types. The assembler optimizations seemed not to like 64-bit
874 data types. The assmebler optimizations thus are now enabled
875 also for BSD systems as opposed to only enable them for Linux.
877 * Do not check for threads at all on BSD systems. Affected
878 file configure.in.pre.
880 * Removed -n and -h options from the Irssi SILC Client since
881 they are not used in silc.
883 * Fixed the prime generation to assure that the first digit
884 of the generated random number is not zero since our conversion
885 routines does not like number strings that starts with zero
886 digit. If zero digit is seen the random number is regenerated.
887 This caused some corrupted RSA keys when the zero first digit
888 was met. Affected file lib/silcmath/silcprimegen.c.
890 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
892 * Fixed WIN32 configuration in the ./configure script.
893 Fixed to include xti.h on environments that has it.
894 Patches by Carsten Ilchmann and andrew.
896 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
898 * Changed the silc_id_create_client_id to be collision
899 resistant. It is now assured that there cannot be created
900 two same client ID's. I suspect that some weird bugs in
901 the server were actually caused by duplicate Client IDs.
902 Affected file silcd/serverid.[ch]. A router receiving
903 new ID now also assures and informs the sending server
904 if the ID caused collision.
906 * Changed the silc_id_create_channel_id to also assure that
907 there are no collisions.
909 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Statement about ignoring the Mutual Authentication flag when
912 performing rekey with PFS was a bit misleading. It is ignored
913 if it was set in the initial negotiation, it cannot be even
914 set in the rekey. Fixed in the ke-auth draft. Started the
915 new versions of the protocol drafts in the doc/.
917 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
919 * Fixed a bug in silc_client_command_identify_save when saving
920 new channel information. The channel name was no duplicated
921 and caused crash on exit. Affected file is
922 lib/silcclient/command_reply.c.
924 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
926 * Fixed the getkey command handling in the server. Send just
927 empty OK reply to the sender if the key could not be fetched
928 (but everything else was ok, like the key just was not available).
929 Changed the public key parameter to optional in the protocol
930 specs so that empty OK reply can be sent. Affected file
933 Added a message to Irssi SILC client to tell to user if the
934 server did not return a public key.
936 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Fixed a channel key regeneration bug. It registered new
939 timeout tasks exponentially until all system resources were
940 used. Affected file silcd/server.c.
942 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
944 * Added the SILC Document generator to the scripts/silcdoc.
945 It can be used to generate the Toolkit Reference Manual out
946 of the source tree. Internally it will also use the RoboDoc
947 generator now imported in util/robodoc.
949 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Added couple of return's in rekey protocol if error orccurred
952 during the protocol. The execution must be terminated.
953 Affected file silcd/protocol.c. Also, terminate the protocol
956 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
958 * The client's Client ID was created initally from the wrong
959 nickname (it could have been in format nick@host) in the
960 silc_server_new_client. Affected file silcd/packet_receive.c
962 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
964 * Added some SILC_LOG_ERROR's to various error conditions
965 if client could not be added to ID cache. Affected files
966 silcd/packet_receive.c and silcd/server.c.
968 * When client's sock->user_data is freed, NULL also the
969 client->router and client->connection pointers. Added check
970 for these pointers being NULL to various places around the
971 code. Affected file silcd/server.c.
973 * Added client->data.registered == TRUE checks to various
974 places around the code to assure that unregistered client's
975 are not handled when it is not allowed. Affected file
978 * Added `bool registered' fields to all
979 silc_idlist_[server|client]_get_* routines to indicate whether
980 the fetched client needs to be registered or not. Affected
981 file silcd/idlist.[ch].
983 * Add your own entry as registered to the ID cache in the
984 server. Affected file server.c.
986 * Fixed a bug in silc_server_new_server. The SilcServer was
987 set as the new server's context instead of SilcServerEntry.
988 This naturally caused some weird bugs.
990 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Do not delete the channel rekey task when adding it
993 for in silc_server_create_channel_key.
995 * Changed the silc_server_create_channel_key to return
996 TRUE or FALSE to indicate the success of the channel key
999 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1001 * Fixed MSVC++ project files and added missing files to
1002 Makefiles under win32/.
1004 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1006 * Do not add TCP_NODELAY flag if the operating system
1007 does not have it defined. Affected files are
1008 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1010 * Fixed buffer overflow from Irssi SILC Client. Affected
1011 file irssi/src/fe-common/core/themes.c.
1013 * Fixed double free in client library in the file
1014 lib/silcclient/client.c when disconnecting from server.
1016 * Applied double free patch from cras to Irssi SILC client.
1017 Affected files irssi/src/core/[modules/expandos].c
1019 * Fixed the disconnection handling to Irssi SILC Client.
1020 The application must call silc_client_close_connection
1021 in ops->connect client operation in case of failure of
1022 the connection. Affected file is
1023 irssi/src/silc/core/client_ops.c.
1025 * Do not set sock->protocol to NULL in the function
1026 silc_client_close_connection after executing the protocol's
1027 final callback since the sock might not be valid anymore.
1028 Affected file lib/silcclient/client.c.
1030 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * Do not enable SILC_THREADS if the linking with libpthread
1033 did not happen. Affected file configure.in.pre.
1035 * Added notion to protocol specification that server must
1036 verify the sent authentication payload with CMODE when
1037 setting the channel founder key. Implemented it to the
1038 server. Affected file silcd/command.c.
1040 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1042 * Added _EXTRA_DIST SILC distribution variable to the
1043 distributions file. It is used to conditionally add extra
1044 files or directories to the specific distribution. Affected
1045 files ./prepare, Makefile.am.pre and distributions.
1047 Removed the `_' from the start of the distribution names.
1050 * Added README.WIN32 for instructions to compile the Toolkit
1053 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1055 * Fixed a double free in disconnection in the server. Affected
1056 file is silcd/server.c.
1058 * Fixed the lib/silcske/groups.c to work now also with GMP
1059 MP library. The string conversion did not work when using
1060 specific base and the base is indicated in the string as well.
1062 * Created win32/ directory which now includes MSVC++ specific
1063 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1064 It will appear only in the toolkit distribution
1066 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1068 * Changed the key material distribution function in case when
1069 the hash output is too short. The data is now concatenated
1070 a bit differently than it used to. Made the change to the
1071 SKE protocol specification.
1073 * Added better GMP detection to configure.in.pre. A patch
1076 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Fixed a minor bug in SKE that might cause some problem on
1079 some platforms. Affected file lib/silcske/silcske.c.
1081 * Added the cookie checking for initiator in the SKE. It checks
1082 that the responder returns the sent cookie unmodified. The
1083 affected file is lib/silcske/silcske.c. Added new SKE
1084 error type INVALID_COOKIE that can be sent during the
1085 negotiation. Fixed some memory leaks as well.
1087 * Added the "invalid cookie" error message to Irssi SILC client's
1090 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Added `task_max' field to the SilcClientParams to indicate
1093 the maximum tasks the scheduler can handle. If set to zero,
1094 default values are used. Affected file lib/silcclient/silcapi.h.
1096 * Fixed memory leaks in silc_client_close_connection. Affected
1097 file lib/silcclient/client.c.
1099 * Added silc_client_del_client_entry to client library to free
1100 all memory of given client entry. Affected file is
1101 lib/silcclient/idlist.[ch].
1103 * Added new functions silc_client_del_channel and
1104 silc_client_del_server to delete channel and server entries.
1105 Affected file lib/silcclient/[silcapi.h/idlist.c].
1107 * Removed silc_client_del_client_by_id from silcapi.h.
1109 * Fixed the INFO command to return the server's own info
1110 correctly when querying by Server ID. Affected file is
1113 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1115 * Removed the non-blocking settings in WIN32 code in the
1116 silc_sock_[read/write] and added SleepEx instead. Affected
1117 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1118 of input data is now checked with FIONREAD and ioctlsocket.
1120 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Call silc_schedule_task_del_by_context in the
1123 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1124 Affected file lib/silccore/silcprotocol.c.
1126 * Call silc_protocol_cancel for active protocols in the
1127 silc_server_close_connection if the funtion
1128 silc_server_free_sock_user_data has not been called.
1129 Affected file silcd/server.c.
1131 * Generic tasks cannot be deleted using the del_by_fd
1132 task deleting function since generic tasks does not match
1133 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1135 * Added a notion to SILCOPER help file that the SILCOPER works
1136 only on router server, not on normal server.
1138 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1140 * Added for WIN32 support for the new scheduler as well.
1141 Affected file lib/silcutil/win32/silcwin32schedule.c.
1143 * Fixed the SHA1 implementation to work on various platforms.
1145 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1147 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1148 API. It is part of the scheduler now. Everything else is
1149 as previously but some functions has changed their names.
1150 Checkout the lib/silcutil/silcschedule.h for the interface.
1151 Updated all applications to use the new interface. Affected
1152 files are lib/silcutil/silcschedule.[ch].
1154 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1156 * Found a bug in the SKE implementation. The HASH value,
1157 specified by the protocol, was not computed correctly. The
1158 public key of the responder was not added to the computation
1159 even though it is mandatory. Affected file lib/silcske/silcske.c.
1160 This unfortunately causes incompatibilities with older
1161 clients and servers.
1163 * Added WIN32 specific network init and uninit functions:
1164 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1165 the Winsock2. Affected file lib/silcutil/silcnet.h and
1166 lib/silcutil/win32/silcwin32net.c.
1168 * Set the socket always to nonblocking mode on WIN32 after
1169 reading data or writing data. Affected file is
1170 lib/silcutil/win32/silcwin32sockconn.c.
1172 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Fixed various compilation problems under WIN32. Affected
1175 files lib/silcutil/win32/silcwin32thread.c and
1176 lib/silcutil/win32/silcwin32schedule.c.
1178 * Removed all _internal.h #includes from public header
1179 files. Internal headers must never be included from
1182 Removed also the lib/silcske/payload_internal.h file.
1184 * All include files that may be needed (public and some others
1185 included by the public headers) by application developers are
1186 now copied to the ./includes directory. It does not copy any
1187 internal headers. Affected file Makefile.defines.pre and all
1188 Makefile.am's under lib/ and subdirs.
1190 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Do not change the ~/.silc directory's permissions automatically.
1193 Affected file irssi/src/silc/core/clientutil.c.
1195 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1197 * Do not cancel the protocol in silc_server_close_connection
1198 it might cause recursion. Now cancelled in the function
1199 silc_server_free_sock_user_data. Affected file silcd/server.c.
1201 * Fixed the silc_server_remove_clients_by_server to regenerate
1202 the channel keys correctly finally. Added also new function
1203 silc_server_remove_clients_channels to actually do it.
1204 Affected file silcd/server.c.
1206 * Fixed the silc_server_new_channel to not crash by giving
1207 wrong router to the new channel. Affected file is
1208 silcd/packet_receive.c.
1210 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1212 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1213 which is given as argument to the silc_client_alloc now.
1214 It can be used to configure the client and set various parameters
1215 that affect the function of the client.
1217 * The USERS command in server did not check whether the channel
1218 is private or secret. Affected file silcd/command.c.
1220 * Added new argument to the USERS command in protocol specification.
1221 The USERS command now can take the channel name as argument
1222 as well. Added support for this in client and server and
1223 updated the protocol specs.
1225 * Completed the GETKEY command in client. It can be now used
1226 to fetch also servers public key not only some clients.
1227 Affected files lib/silcclient/command[_reply].c.
1229 * Added silc_client_get_server to return server entry by the
1230 server name. Affected files lib/silcclient/silcapi.h and
1233 * Redefined the IDENTIFY command in protocol specification to be
1234 more generic. It now can be used to query information about
1235 any entity in the SILC Network, including clients, servers and
1236 channels. The query may be based either the entity's name
1237 or the ID. Added support for this in both client and server.
1239 Affected files silcd/command.c and lib/silcclient/command.c
1240 and command_reply.c.
1242 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1243 the _from_client and _from_server functions. Affected file
1246 * Added silc_client_get_channel_by_id_resolve to the file
1247 lib/silcclient/silcapi.h to resolve channel information by
1248 its ID. Added also silc_client_get_channel_by_id that
1249 does not resolve it from the server.
1251 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Added SilcServerEntry context into the client library
1254 to represent one server. The INFO command now allocates
1255 these to save the resolved server info. For now on the
1256 client library will also keep information about servers,
1257 connected and resolved with INFO.
1259 The INFO command now allocates the SilcServerEntry context
1260 and saves the server info there. The COMMAND_REPLY in
1261 the INFO now returns the parameters to application in
1262 same order as defined in the protocol specification.
1264 The entries are cached in the client->server_cache.
1266 * The INFO command is now issued after received the Client ID
1267 from the server. Affected file lib/silcclient/client.c.
1269 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1270 to the application as the mode changer might be server.
1271 It is guaranteed that NULL is not returned anymore to the
1272 application. Affected file lib/silcclient/client_notify.c.
1274 The ID Type is now also passed to the application so that
1275 it can check whether the returned entry is SilcClientEntry
1278 Added new function silc_client_get_server_by_id to return
1279 the server entry by ID. Affected files are the
1280 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1282 * Do not create the channel in the Irssi SILC Client when issuing
1283 the JOIN command but when received the sucessful JOIN command
1284 reply. Otherwise the channel might get created even though we
1285 could not join it. The Affected file is
1286 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1288 * Fixed a channel joining bug in router. The router must also
1289 check the channel modes, invite and ban lists etc. when serving
1290 the JOIN command sent by normal server. Affected file is
1291 silcd/command.c. The router now resolves the client's
1292 information from the server who sent the JOIN command if it
1293 does not know it, and processes the JOIN command only after
1296 * Changed the SilcCommandCb to take new argument; void *context2.
1297 Affected file lib/silccore/silccommand.h
1299 The second argument in the command callbacks in the server now
1300 includes the SilcServerCommandReplyContext if the command was
1301 called as pending command callback from the command reply.
1302 Otherwise it is NULL. When called as pending the status of the
1303 command reply will be checked and if it was erronous the
1304 error will be sent to the original sender of the command.
1305 This way the client always receives the error messages even
1306 though the server was actually the one who received the error
1307 when it resent the command to router, for example. Affected
1308 files silcd/command[_reply].[ch].
1310 * Fixed sending WHOWAS command's error message to client if
1311 the requested client could not be found. It was missing.
1314 * Changed the CMODE and CUMODE commands reply arguments in the
1315 protocol specification. The Channel ID is now sent in both
1316 of the commands to identify the channel. Implemented this
1317 new feature to the client and server. Affected files
1318 lib/silcclient/command_reply.c and silcd/command.c.
1320 * Made better checks for invite and ban lists in the JOIN
1321 command in server. Affected file silcd/command.c.
1323 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * The server now performs the incoming host IP/DNS lookup
1326 using the silc_socket_host_lookup and thus does not block
1327 the server anymore. Affected file silcd/server.c.
1329 * Completed the multi-thread support for SILC Scheduler in
1330 the lib/silcutil/silcschedule.c.
1332 * Fixed the configure.in.pre to detect the pthread correctly
1335 * Fixed a deadlock in silc_task_queue_wakeup in the file
1336 lib/silcutil/silctask.c.
1338 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1340 * Added new function silc_schedule_wakeup that is used in
1341 multi-threaded environment to wakeup the main thread's
1342 schduler. It needs to be used when a thread adds a new task
1343 or removes a task from task queues. After waking up, the
1344 scheduler will detect the task queue changes. If threads
1345 support is not compiled in this function has no effect.
1346 Implemented the wakeup mechanism to both Unix and WIN32
1347 systems. Affected files are lib/silcutil/silcschedule.[ch],
1348 lib/silcutil/unix/silcunixschedule.c and the
1349 lib/silcutil/win32/silcwin32schedule.c.
1351 * Added new function silc_task_queue_wakeup to wakeup the
1352 scheduler by the specified task queue. Affected file
1353 lib/silcutil/silctask.[ch].
1355 * The silc_socket_host_lookup_start now wakes up the scheduler
1356 after adding the timeout task. Affected file is
1357 lib/silcutil/silcsockconn.c.
1359 * The silc_socket_host_lookup is synchronous now if the threads
1360 support is not compiled in. However, the callback is still
1361 called asyncronously through the scheduler, anyway. Affected
1362 file lib/silcutil/silcsockconn.c.
1364 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Added new function silc_socket_host_lookup to perform
1367 asynchronous IP and FQDN lookups for the socket connection.
1368 Affected files lib/silcutil/silcsockconn.[ch].
1370 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1373 that may or may not compile the mutex support in.
1375 Changed the silc_mutex_alloc interface. It allocates the
1376 mutex now to the sent pointer and returns TRUE or FALSE.
1378 Affected file lib/silcutil/silcmutex.h.
1380 * Wrote the SILC Task Queue interface to support multi-threads.
1381 Affected file lib/silcutil/silctask.[ch].
1383 * Wrote the SILC Scheduler to support multi-threads. Affected
1384 file lib/silcutil/silcschedule.c.
1386 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1388 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1389 in lib/silcutil/win32/.
1391 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Defined SILC Mutex API and SILC Thread API and implemented
1394 them for Unix. Affected files are
1395 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1396 lib/silcutil/unix/silcunixmutex.c and
1397 lib/silcutil/unix/silcunixthread.c.
1399 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * Fixed the silc_server_remove_clients_by_server's channel
1402 key re-generation. The hash table handling was incorrect
1403 and would not work with many channels. Affected file is
1406 * Fixed some memory leaks around the server code.
1408 * Rewrote the silc_server_get_users_on_channel to support IPv6
1409 based Client ID's. Affected file silcd/server.c.
1411 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1412 specification. However, a separate document must be written
1413 to define the detailed signing procedure and the payload
1414 associated with the flag. Defined the flag to the
1415 lib/silccore/silcchannel.h as well.
1417 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1419 * Changed the dynamic tables to static size tables in the
1420 lib/silccrypt/silchmac.c.
1422 * Removed GCC dependencies from the code. A patch by cras.
1424 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1426 * Do not show the error "Error receiving packet bla bla"
1427 in server if it really was not an error (-2 means that reading
1428 is pending). Affected file silcd/server.c.
1430 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1432 * Fixed a possible crash in silc_server_remove_clients_by_server
1433 in silcd/server.c. Fixed there also some memory leaks.
1435 * Fixed the silc_idlist_replace_client_id. It could replace
1436 wrong key in the hash table. Affected file silcd/idlist.c.
1438 * Do not check whether there are global users on the channel
1439 if the channel->global_users is FALSE. Affected functions
1440 silc_server_remove_from_one_channel and
1441 silc_server_remove_from_channels in silcd/server.c. Also,
1442 do not check if the removed client is local as we can be
1443 sure that global client was not removed from the channel
1444 and checking for global users is not needed.
1446 * The silc_server_remove_clients_by_server now re-generates
1447 the channel keys correctly for those channels that had
1448 clients removed from them. Affected file silcd/server.c.
1450 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1452 * Found the reason of random crashes in the server. We weren't
1453 ignoring the SIGPIPE signal (which can be sent in write())
1454 and it crashed the server. Affected file silcd/silcd.c.
1456 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Assure that sock->user_data is not NULL in the function
1459 silc_server_packet_send in silcd/packet_send.c.
1461 * Disconnect the remote connection if it could not be added
1462 to any ID lists in the server. The affected file is
1465 * Check in silc_server_packet_send[_real/dest] that the
1466 socket is not disconnecting and ignore the data if it is.
1467 Affected file silcd/packet_send.c.
1469 * Define inline to __inline on native WIN32 compilation.
1470 Affected file includes/silcwin32.h.
1472 * Added some explicit type casts for inline code since MSVC
1473 require them. Affected files lib/silcutil/silcbuffer.h,
1474 lib/trq/silcdlist.h and lib/trq/silclist.h.
1476 * Print warning in log files from now on if the packet
1477 decryption fails. Affected file silcd/server.c.
1479 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1481 * Changed the `say' client operation's interface to accept
1482 new `type' argument to indicate the type of the message sent
1483 by the library. The application may filter the library's
1484 messages according the type. The affected file is the
1485 lib/silcclient/silcapi.h.
1487 * Added two new functions to lib/silcclient/silcapi.h:
1488 silc_client_del_client and silc_client_del_client_by_id.
1489 Affected file lib/silcclient/idlist.c.
1491 * Moved the clientincludes.h from includes/ to silc/ and
1492 serverincludes.h from includes/ to silcd/.
1494 * The modes for the CMODE and CUMODE are now passed as
1495 uint32 for application with COMMAND_REPLY. The affected
1496 file is lib/silcclient/command_reply.c.
1498 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1500 * /WHOIS without arguments shows client's own information.
1501 Affected file lib/silcclient/command.c.
1503 * Changed PING to not accept any arguments. The specs
1504 says that client can ping only the connected server so
1505 requiring an argument is not needed. Affected file is
1506 lib/silcclient/command.c.
1508 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1510 * Fixed a fatal bug in private message sending and reception
1511 encryption and decryption when using private message keys.
1512 The implementation was incorrect and did not follow the
1513 specification. It causd that some of the message were
1514 lost since it did not use the sending and receiving keys
1515 as the protocol suggests. This has been fixed and will cause
1516 incompatibilities with older clients when sending private
1517 message encrypted with private message keys. Affected files
1518 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1519 and various other in Irssi SILC Client.
1521 Added `responder' boolean argument to the functions
1522 silc_client_add_private_message_key[_ske] to indicate when
1523 the key is added as responder or initiator of the key
1526 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Removed the silc_ske_check_version function and created
1529 a SilcSKECheckVersion callback. Added also a function
1530 silc_ske_set_callbacks that is now used to set all SKE
1531 callbacks. The callback functions are not given to
1532 the SKE functions anymore, but this function is used to
1535 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1537 * Added `silc_version' argument to the silc_client_alloc
1538 to define the version of the application for the library.
1539 The library will use the version string to compare it
1540 against the remote host's (usually a server) version
1541 string. Affected file lib/silcclient/silcapi.h
1543 * Added the KE protocol context to Key Agreement context
1544 in client library so that we can abort the SKE if it
1545 is in process when we get timeout. Affected file is
1546 lib/silcclient/client_keyagr.c.
1548 * Do not resolve the client ID forever if it returns in the
1549 first time that such client does not exist. This was done
1550 for example with private message. Affected file is
1551 lib/silcclient/client_prvmsg.c.
1553 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1555 * Do not add regex.h for WIN32. The affected file
1556 includes/silcincludes.h.
1558 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1559 not work yet 100%. It generates the DLL's automatically
1560 when compiling with --with-win32 under cygwin.
1562 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * lib/contrib/regex.c is not compiled on WIN32.
1566 * Added silc_net_get_socket_opt function to the
1567 lib/silcutil/silcnet.h.
1569 * Added includes/silcwin32.h for WIN32 specific includes
1572 * Do not use ptime structure or any of the posix process
1573 functions on WIN32 in lib/silccrypt/silrng.c.
1575 * Added silc_gettimeofday to provide generic function
1576 for struct timeval on all platforms. Added the function
1577 to lib/silcutil/silcutil.h.
1579 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1582 library as they clearly belong there. As a plus side we
1583 can make the actual socket connection routines platform
1586 Added also new generic function silc_socket_read and
1587 silc_socket_write (that used to be silc_packet_[read/write].
1588 The implementation of these are platform specific.
1590 * Added WIN32 specific routines of silc_socket_[read/write]
1591 to lib/silcutil/win32/silcwin32sockconn.c.
1593 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Added preliminary support for native WIN32 compilation under
1596 cygwin (using the -mno-cygwin option for GCC) to the
1597 ./configure.in.pre. The --with-win32 now prepares the
1598 compilation for native WIN32.
1600 * Rewrote the SILC Scheduler interface in the file
1601 lib/silcutil/silcschedule.h. The scheduler is now context
1602 based and does not have anymore any global static scheduler.
1603 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1604 and created lib/silcutil/win32 directory for WIN32 based
1607 * Added Unix specific network routines to the
1608 lib/silcutil/unix/silcunixnet.c and the old
1609 lib/silcutil/silcnet.c includes now only generic routines.
1611 Added WIN32 specific network routines to the
1612 lib/silcutil/win32/silcwin32net.c.
1614 * Added Unix specific utility functions from the
1615 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1617 * Added WIN32 SILC Scheduler to the file
1618 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1621 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Do not handle JOIN notify in the server if the target client
1624 is not registered (idata->registered == FALSE). The affected
1625 file is silcd/packet_receive.c.
1627 * Update the nickrec->founder in event_cumode in the Irssi SILC
1628 client. Affected file irssi/src/silc/core/silc-channels.c.
1630 * Fixed the CUMODE_CHANGE notify handling in the server when
1631 server and router are announcing their clients on channels.
1632 Now the mode changes are saved and notified correctly. The
1633 affected file is /silcd/packet_receive.c.
1635 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1636 They really did not replace the cache entry in the ID Cache.
1637 Now they do that. Affected file silcd/idlist.c.
1639 * Fixed the KICK notify handling in the Irssi SILC client to
1640 update the channel records so that the kicked client does not
1641 appear to be on the channel. The affected file is
1642 irssi/src/silc/core/silc-channels.c.
1644 * Always update the conn->current_channel when executing command
1645 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1647 * Fixed the KILL notify handling in Irssi SILC client to remove
1648 the killed client on all channels.
1650 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Fixed the silc_parse_command_line to remove extra spaces
1653 from the start and end of the arguments. Affected file is
1654 lib/silcutil/silcutil.c.
1656 * Cancel and free any active protocol in the function
1657 silc_server_close_connection. Affected file silcd/server.c.
1659 * Cancel and free any active protocol in the function
1660 silc_client_close_connction. Affected file is
1661 lib/silcclient/client.c.
1663 * Do not execute the KILL command for clients that are in
1664 history (ie. they are not in the network). Affected file is
1667 * Fixed KILL notify handling, client does not crash anymore.
1668 Affected file irssi/src/silc/core/silc-channels.c.
1670 * Reduced the default packet buffer size from 2048 to 1024 in
1671 lib/silccore/silcpacket.c.
1673 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1674 counter to the SKE context that is incresed when the SKE library
1675 performs async operation outside the library. If the outside
1676 process frees the SKE context and FREED status will be set
1677 and the library will detect after the sync operation that the
1678 libary is freed. The affected files are
1679 lib/silcske/silcske[_status].[ch].
1681 * Resolve the client entry information in the function
1682 silc_client_channel_message to assure that NULL pointer is not
1683 passed as client entry to the application. */
1685 * Fixed the task timeout calculation to assure that there is
1686 never negative timeouts. The affected file is
1687 lib/silcutil/silcschedule.c.
1689 * Fixed the channel user mode notification sending in server.
1690 It was sent point-to-point to the router (or to server by router)
1691 but it needs to be destined to a channel. The routines now
1692 supports sending the channel user mode notifys to the channels
1693 when announcing clients and channels. Affected files are
1694 silcd/server.c and silcd/packet_receive.c.
1696 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1697 It did not actually replace the old channel entry in the cache.
1698 Affected file lib/silcclient/client_notify.c.
1700 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1702 * Fixed a possible crash in silc_packet_send_prepare. It now
1703 assures always that there is enough space in the buffer and
1704 at the tail area of the buffer (for MAC).
1706 Fixed the inbound buffer reallocation in silc_packet_read.
1707 It was old code and did not handle the reallocation correctly.
1710 The affected file is lib/silccore/silcpacket.c.
1712 * Fixed buffer overflow in silc_parse_nickname in the file
1713 lib/silcutil/silcutil.c.
1715 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1717 * make install generates new server keys only if there is not
1720 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1723 Added check that if the NOREPLY is set then we will not send
1724 the away message. This avoids infinite loop of away messages
1725 if both clients are away. The affected file is
1726 lib/silcclient/client_prvmsg.c.
1728 * Fixed client crash if /NICK was given without arguments.
1729 Affected file lib/silcclient/command.c.
1731 * Server does not send the invite list in INVITE command back
1732 to the client if the list was not altered. Added this notion
1733 to the protocol spec as well. Affected file silcd/command.c.
1735 Fixed possible crash in INVITE command by checking the
1736 value of silc_server_get_client_route command.
1738 * Fixed the INVITE notify type handling. The arguments are now
1739 taken in correct order and client does not crash. The affected
1740 file is irssi/src/silc/core/silc-channels.c.
1742 Removed the "Inviting xxx to channel" message from the
1743 client library away and let the application handle it.
1744 Affected file lib/silcclient/command.c. Added that message
1745 to Irssi SILC client's message formats.
1747 * Fixed CMODE command crash in client. It now checks the
1748 amount of arguments correctly and does not crash. The affected
1749 file is lib/silcclient/command.c.
1751 * Do not create new channel automatically in silc_channels_join
1752 but check whether the channel by that name already exists.
1753 Affected file irssi/silc/core/silc-channels.c.
1755 * Do not send the SERVER_SIGNOFF to router if the disconnected
1756 entity was the router. Affected file silcd/server.c.
1758 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1759 SILC client as it was missing from there.
1761 Added the handling of the KICK notify to the Irssi SILC client
1762 as it was missing. Added "you have been kicked" message to
1763 Irssi SILC client's message modules formats.
1765 Added the handing of the KILL notify to the Irssi SILC client
1766 as it was missing. Added the kill message module formats
1769 The affected file is irssi/src/silc/core/silc-channels.c.
1771 * The router did not save the channel mode the server announced.
1772 Affected file silcd/packet_receive.c.
1774 * Fixed a possible crash in INFO command in server. If the
1775 server did not provide the server info it crashed. Affected
1776 file silcd/command.c.
1778 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Fixed the GETKEY command in the server to check also the
1781 global list. Otherwise the GETKEY would not work correctly
1782 in normal SILC server. Affected file silcd/command.c.
1784 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1786 * Fixed GETKEY crash, it crashed if the command did not succseed.
1788 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1790 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1791 is now real and not just an macro interface to GMP.
1793 Removed the entire GMP from the source tree and imported new
1794 NSS MPI library instead. Reason for removing GMP is that it is
1795 extremely large and compiles extremely slow. The NSS MPI
1796 is only a few files and compiles in less than 10 seconds.
1797 The speed is also about the same as GMP. The MPI is imported
1798 to lib/silcmath/mpi.
1800 If the system has GMP installed we will still use the GMP.
1801 If it is not then the NSS MPI will be compiled.
1803 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Merged a long nickname (127 characters long) crash bugfix from
1806 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1808 * Merged a freed memory reference bugfix from Irssi CVS tree.
1809 Affected file irssi/src/core/commands.c.
1811 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Added the server's public key sving and verification to the
1814 server when performing the SKE. This was missing and the
1815 remote server's (or router's) public key was accepted without
1816 checking whether we have it previously or trust it at all.
1817 Affected file silcd/protocol.c.
1819 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Check in the silc_server_timeout_remote if protocol is active
1822 and make sure that the protocol's final callback is called so
1823 that all memory if freed. Affected file silcd/server.c.
1825 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * silc_server_whois_send_reply crashed the server if the nickname
1828 was 127 characters long. Affected file silcd/command.c.
1830 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * Added sanity check to the silc_server_new_client. If the hostname
1833 is provided inside username then check that the provided hostname
1834 really is the same as the resolved one. If the hostname was not
1835 resolved then check it from the public key. Affected file is
1836 silcd/packet_receive.c.
1838 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1839 if the server disconnected us and the connection is not valid
1840 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1842 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1843 the library to the lib/silcutil/silcutil.[ch].
1845 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * Close log file after open. Affected file
1848 lib/silcutil/silclog.c.
1850 * Check whether sock == NULL in silc_client_send_packet and return
1851 if it is. Affected file lib/silcclient/silcclient.c.
1853 * Check rec->entry == NULL in the Irssi SILC Client before
1854 sending the channel message. Affecte file is
1855 irssi/src/silc/core/silc-servers.c.
1857 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Merged a splitted window bugfix from Irssi CVS tree. The
1860 affected file is irssi/src/fe-text/textbuffer-view.c.
1862 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1863 It did not print nickname.
1865 * Improved the distributions system a bit.
1867 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1870 irssi/src/fe-text/gui-window.c.
1872 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1873 to in-active server. The affected file is
1874 irssi/src/silc/core/client_ops.c.
1876 * Resolve the client in USERS command reply if the entry does
1877 not have username resolved. The affected file is
1878 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1879 command to WHOIS command to really resolve stuff. The USERS
1880 is not used any more in any critical section so WHOIS can
1881 be used even though it might be slower than IDENTIFY.
1883 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1886 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Changed the protocol API a bit more consistent in the
1889 lib/silccore/silcprotocol.[ch].
1891 * Changed the following headers to ROBODoc format:
1893 lib/silccore/silcpayload.h
1894 lib/silccore/silcprotocol.h
1895 lib/silccore/silcsockconn.h
1897 All core library headers are now formatted.
1899 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1901 * Fixed a bug in Irssi SILC client; do not show that you are
1902 server/router operator if you really are not. Affected file is
1903 irssi/src/silc/core/client_ops.c.
1905 * Renamed silc_command_free_payload to silc_command_payload_free.
1906 Affected file lib/silccore/silccommand.h
1908 * Added silcmath.h to include the prototoypes of various routines
1909 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1912 * Changed the following headers to ROBODoc format:
1914 lib/silccore/silcchannel.h
1915 lib/silccore/silccommand.h
1916 lib/silccore/silcid.h
1917 lib/silccore/silcidcache.h
1918 lib/silccore/silcmode.h
1919 lib/silccore/silcnotify.h
1920 lib/silccore/silcpacket.h
1921 lib/silcmath/silcmath.h
1923 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Added checking to the server code not to start the server if
1926 ciphers and stuff are not configured properly. Affected files
1927 silcd/serverconfig.[h] and silcd/server.c.
1929 * Changed the layout of the header files of the public interfaces
1930 in the SILC libraries. The new layout supports ROBODoc
1931 documentation tool (and some others) so that it is easy to create
1932 a library reference manual. All the other headers and source
1933 code must still follow the CodingStyle document. Also source
1934 code must not include these ROBODoc stuffs, only the headers.
1935 Furthermore, all public interface headers must now be named
1936 by using `silc' prefix, example: silcapi.h, silccipher.h.
1937 Some files were renamed due to this. All the other headers
1938 must not be used as public interfaces. I will update the
1939 CodingStyle document later. Changed following headers, so far:
1941 lib/silcclient/silcapi.h
1942 lib/silccore/silcauth.h
1943 lib/silccore/silcprivate.h
1944 lib/silccrypt/silcdh.h
1946 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Removed silc_client_packet_send_flush from the client library
1951 as it is not needed. Affected file lib/silcclient/client.[ch].
1953 * Added printing of message of unresolved authentication method
1954 to the Irssi SILC client. Added it to the module formats.
1955 Removed the same message from the client library.
1957 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1959 * Added new distribution feature, DISTLABEL. Every distribution
1960 can define own preprocessor label that can be used in the
1961 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1962 file distributions, acconfig.h.pre and prepare.
1964 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1966 * Added Makefile.defines_int to include the actual definitions
1967 for Makefile.defines.in. Tested the new distribution system,
1968 created distributions and tested installation.
1970 * Added AWAY message printing to the Irssi SILC client. Added
1971 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1973 * Added SCONNECT command to call the SILC's CONNECT command.
1974 Cannot use CONNECT directly since Irssi uses that internally.
1975 Affected file irssi/src/silc/core/silc-servers.c.
1977 Added ACTION local command. It is same as ME command but takes
1978 the channel as mandatory argument.
1980 Rewrote some of the Irssi's help files to suite for SILC
1983 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Added Makefile.defines[.in] that should for now on be included
1986 in all Makefile.am file in the source tree. That file includes
1987 all common compilation definitions for SILC source tree.
1989 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Minor changes to the ./prepare script to change the package
1992 name according the distribution name to the configure.in.
1994 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Created new distribution system. Added file `distributions'
1997 that defines all the distributions that can be created out of
1998 the SILC source tree. The ./prepare script now reads that
1999 file to determine how to prepare the distributions. The
2000 first argument to the ./prepare is the name of the distribution
2001 and second is the version of the distribution. If given
2002 without arguments it creates the default (toolkit) distribution
2003 with the default version (defined in ./prepare).
2005 All Makefile.am files that are subject to the distributions
2006 are now named as Makefile.am.pre. These are ./Makefile.am
2007 and lib/Makefile.am. Others may be changed later.
2009 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Added invite list, ban list, some key management and connection
2012 error message printing to module formats in the Irssi SILC client.
2014 * Added new silc_client_set_away_message to set the away message
2015 that is back to the person who sent private message. The
2016 affected file lib/silcclient/silcapi.h and the
2017 lib/silcclient/client_prvmsg.c.
2019 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Fixed the private message sending in the Irssi SILC client,
2022 added local command KEY to the Irssi SILC client.
2024 Added key management and key agreement message formats to the
2025 irssi/src/fe-common/silc/module-formats.[ch].
2027 Added USERS (alias WHO) printing, server/router operator
2028 indication and LIST command printing to the module formats.
2030 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Fixed channel joining notify handling, cumode notify handling
2033 from Irssi SILC client.
2035 * Added SILC specific module-formats to the Irssi SILC client so
2036 that SILC specific message hilighting, colors etc is possible.
2037 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2039 Added channel mode, channel user mode, actions, notices,
2040 whois and whowas printing to the the module-formats.c.
2042 * Fixed a bug in channel deletion in the server. The channel
2043 is not left to the cache even if the channel founder auth mode
2044 is set when there are no users anymore on the channel. Affected
2045 file silcd/server.c.
2047 * The silc_net_localhost now resolves the entire hostname including
2048 the domain name. Affected file lib/silcutil/silcnet.c.
2050 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2052 * Changed the ask_passphrase client operation to be ascynchronous.
2053 It has now a completion callback and a context that the
2054 application must call after it has got the passphrase from
2055 the user. Affected files lib/silcclient/silcapi.h,
2056 lib/silcclient/protocol.c, lib/silcclient/command.c and
2059 Added SilcAskPassphrase callback that the application calls
2060 to deliver the passphrase to the library.
2062 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2063 The public key verification and especially a certificate
2064 verification is asynchronous procedure.
2066 Added new SILC_SKE_STATUS_PENDING status to indicate the
2067 request is pending and a callback will be called to finalize
2070 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2071 indicate that remote end did not send its public key (or
2072 certificate), even though we require it. Added check for this
2073 condition in the SKE. This was a security bug, now fixed.
2075 Defined new SilcSKEVerifyCbCompletion callback that is called
2076 when the verification process is completed.
2078 The affected files lib/silcske/silcske_status.h and
2079 lib/silcske/silcske.[ch].
2081 * Changed the verify_public_key client operation to be async
2082 as well. Defined SilcVerifyPublicKey callback that is used to
2083 indicate the success of the public key verification process.
2085 Changed the server and client to use the new async client
2088 * Changed the Irssi SILC client's internal scheduler to be called
2089 twice as many times as it used to be. As a result the client
2090 should be a bit faster now. Affected file is
2091 irssi/src/silc/core/silc-core.c.
2093 * Added support to Irssi SILC client of asynchronous public key
2094 verification and passphrase inquiry. Affected file is
2095 irssi/src/silc/core/silc-core.c.
2097 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Do not say "You have left channel %s" in client library.
2100 Moved it to the application. Affected files are
2101 lib/silcclient/command.c and silc/client_ops.c.
2103 * Fixed silc_client_get_clients. Command context was not
2104 duplicated and was freed memory in the callback. Affected
2105 file lib/silcclient/idlist.c.
2107 * Do not say "you are now talking..." on JOIN command in the
2108 client library. The appliation must handle it.
2110 * Do not say ".. changed topic to" in command reply in the
2111 client libary. The application must handle it.
2113 * Fixed TOPIC command sending in the client library.
2115 * Fixed a memory leak in silc_client_command_free in the file
2116 lib/silcclient/command.c.
2118 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Imported a modified version of Irssi client to the source tree.
2121 The Irssi will be used to create a new client called
2122 Irssi SILC. Imported to irssi/.
2124 Added silc_core_init_finish function to the Irssi. Affected
2125 file irssi/configure.in.
2127 A lot changes in the Makefile.ams around the irssi tree.
2129 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Do not rehash if the new size is same as the old size of the
2132 hash table, in the silc_hash_table_rehash*. The affected file
2133 lib/silcutil/silchashtable.c.
2135 * Replaced hash_table_del_by_context calls from the server
2136 (when channel->user_list and client->channels) to the
2137 hash_table_del as it is sufficient and faster.
2139 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Added silc_hash_table_list, silc_hash_table_get and the
2142 SilcHashTableList structure to provide an alternative way to
2143 traverse the hash table. The affected files are
2144 lib/silcutil/silchashtable.[ch].
2146 * Changed the server's idlist routines to use the hash table
2147 routines to optimize the code.
2149 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Replaced the client entry's `channel' list and channel entry's
2152 `user_list' list to hash tables for optimized lookup. Changed
2153 the code to use the hash table interface around the code.
2154 Affected file lib/silcd/idlist.[ch].
2156 * Added `auto_rehash' boolean argument to the function
2157 silc_hash_table_alloc to indicate whether the hash table should
2158 auto-rehash when it thinks is appropriate time. It will
2159 increase the hash table size if the there is twice as much
2160 entries in the table than the size of the table, and will
2161 decrease the size if there are twice as less entries than
2162 the size of the table.
2164 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2168 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * silc_idcache_purge_by_context deletes the entry now by context
2171 as it is supposed to do. Affected file lib/silccore/idcache.c.
2173 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2174 client is not anymore valid (WHOWAS givens the info) and not
2175 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2177 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2179 * Removed the `data' and `data_len' arguments from the ID Cache
2180 interfaces and added `name' argument. ID Cache does not handle
2181 anymore the binary data only a names associated with given ID.
2183 * When hashing a Client ID with silc_hash_id the entire ID is
2184 not hashed anymore, instead only the hash of the Client ID is
2185 hashed. This way we can access the Client ID from the cache
2186 with Client ID but with the hash of the ID (which is a hash of
2187 the nickname) as well without any difference in performance.
2189 Added also silc_idcache_find_by_id_one_ext to do one on one
2190 searching when we have the actual ID. Added also function
2191 silc_hash_client_id_compare. The affected files are
2192 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2194 * When hashing the name associated with a ID it is always done
2195 in lowercase. This way we can access the cache without worrying
2196 about case-sensitivity, even though, for example nicknames are
2199 * Fixed a bug in server with channel message sending. It put
2200 wrong ID type as destination ID. The affected file
2201 silcd/packet_send.c.
2203 * silc_idcache_del_by_context now deletes from all hash tables
2204 by context. Affected file lib/silccore/idcache.c.
2206 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2208 * Changed the client library to use the new ID Cache interface.
2209 Changes around the source tree.
2211 * Added silc_hash_table_rehash_ext to rehash with specific
2212 hash function. Affected file lib/silcutil/silchashtable.[ch].
2214 * Added silc_hash_string_compare to compare two strings in the
2215 hash table. Affected file lib/silcutil/silcutil.[ch].
2217 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Added new function silc_idcache_del_by_context into the
2220 lib/silccore/idcache.[ch].
2222 * Changed the server's ID list routines to use the new ID Cache
2223 interface. Changes around the source tree.
2225 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2227 * Added silc_hash_table_del[_by_context]_ext functions in to the
2228 lib/silcutil/silchashtable.[ch].
2230 Removed silc_hash_table_find_all* routines and added new
2231 silc_hash_table_find_foreach to replace them.
2233 Added silc_hash_table_replace_ext function as extended
2234 replacing function. Separated the simple hash table interface
2235 from the extended hash table interface in the file
2236 lib/silcutil/silchashtable.h.
2238 * Fixed minor bugs and changed it to use some of the new
2239 hash table functions in lib/silccore/idcache.c
2241 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2243 * Added new function silc_hash_table_find_all to return all keys
2244 in the hash table by the specified key. As the hash table is
2245 collision resistant it also makes it possible to have several
2246 duplicate keys in the hash table. This function may be used to
2247 find all of the keys from the hash.
2249 Added user_context arguments to the SilcHashFunction,
2250 SilcHashCompare and SilcHashDestructor to deliver user specified
2253 Added new fuctions silc_hash_table_find[_all]_ext to do
2254 extended lookup with specified hash and compare functions and
2255 specified user contexts.
2257 Added new function silc_hash_table_add_ext to add the key
2258 with specified hash function and user context.
2260 Added new function silc_hash_table_foreach to traverse all
2261 entrys in the hash table. Added SilcHashForeach callback
2264 Added new function silc_hash_table_del_by_context to delete
2265 the entry only if the context associated with the key matches.
2267 Affected files are lib/silcutil/silchashtable.[ch].
2269 * Removed silc_hash_[server/client/channel]_id and added just
2270 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2271 silc_hash_id_compare to compare two ID's using as the hash table
2272 comparison function. Added also silc_hash_data to hash
2273 binary data and silc_hash_data_compare to compare it.
2275 * Removed silc_idlist_find_client_by_hash as it is not needed
2276 anymore. Affected file silcd/idlist.[ch].
2278 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2279 to use internally the SilcHashTable. The new ID Cache is a lot
2280 faster than the old one. Some of the ID Cache interface was also
2281 rewritten and obsolete and stupid functions were removed.
2283 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Added entry_count field to the SilcHashTable to keep the number
2286 of the entries in the table. Implemented the function
2287 silc_hash_table_rehash. Added new function
2288 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2290 Fixed a minor bug in silc_hash_table_free.
2292 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2293 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2294 into the lib/silcutil/silcutil.[ch].
2296 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Implemented a collision resistant hash table into the
2299 lib/silcutil/silchashtable[ch]. See the header and the source
2300 for the SilcHashTable API.
2302 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Merged dotconf version 1.0.2 into lib/dotconf.
2306 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Do not compile anything in lib/silcsim/* if the SIM support
2309 is not enabled. The tree should now compile without problems
2312 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2314 * Compiled the SILC under cygwin. Compiled and tested briefly
2315 without problems. More tests needed. The SIMs didn't compile
2318 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2320 * Fixed possible crash in silc_get_username in the
2321 lib/silcutil/silcutil.c.
2323 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Fixed a va_arg in silc/client_ops.c.
2327 * Oops, RC5 routines were named AES and caused some problems
2328 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2330 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Added new SilcIDIP structure into the lib/silccore/id.h and
2333 replaced the old `ip' fields from all SILC ID's to that type.
2334 This is a step towards IPv6 support.
2336 The silc_id_get_len takes now the ID as an extra argument.
2337 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2338 both IPv4 and IPv6 based ID's.
2340 The affected files are lib/silccore/id.[ch] and other files
2341 around the tree using these routines.
2343 * Removed the ID length arguments in server from various
2344 silc_server_send_notify_* routines -> they are not needed
2347 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Fixed memory leak in silc_encode_pem_file in the file
2350 lib/silcutil/silcutil.c.
2352 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Check minor version as well in the SKE. Affected files are
2355 silcd/protocol.c and lib/silcclient/protocol.c.
2357 * Added --identifier option to the server so that an identifier
2358 can be when creating the public key for the server. Affected
2359 file is silcd/silcd.c.
2361 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2362 lib/silccrypt/silcpkcs.c.
2364 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Register default ciphers and stuff when using -C option with
2367 the server. Affected file sildc/silcd.c.
2369 * Put back the servers public key filename format, it is better
2370 than the new one. For now, the client keys are saved with the
2371 new filename format. The affected file silc/client_ops.c.
2373 * Implemented the Cipher API for the rest of the ciphers that
2374 did not implement it or implemented it the wrong way.
2376 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Register default ciphers and stuff when using the -S option
2379 in the client. Affected file silc/silc.c. Same also when
2380 creating new key pair with -C option.
2382 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Fixed the silc_verify_public_key client operation function to
2385 save the public keys differently. The fingerprint is now
2386 used as filename and not the hostname. This way also the
2387 client keys are saved uniquely and not with hostnames. The
2388 affected file is silc/client_ops.c.
2390 * Trimmed the silc_hash_fingerprint function to remove extra
2391 whitespaces from the end of the fingerprint. The affected
2392 file is lib/silccrypt/silchash.c.
2396 * Added silc_cipher_register_default function to register all
2397 default ciphers. It can be used when configuration files
2398 does not exist and the application does not want any specific
2399 ciphers in any specific order.
2401 The SilcDList is now used as silc_cipher_list dynamically
2402 allocated cipher list. Removed the static list all together
2403 and now all ciphers must be allocated to the dynamic list.
2404 The silc_cipher_alloc routine was changed to check only the
2407 All silc_cipher_* routines that used to return int returns
2410 The affected files lib/silccrypt/silccrypt.[ch].
2412 * The same thing was done to silc_hash_* as for silc_cipher_*
2413 routines. Affected files lib/silccrypt/silchash.[ch].
2415 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2416 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2417 Added also silc_pkcs_[un]register[_default] functions.
2418 Removed the data_context from the PKCS API.
2420 * Added silc_hmac_register_default function to register default
2421 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2422 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2423 to unregister all hmacs at once.
2425 * Register the default ciphers, hash functions, PKCSs and HMACs
2426 if client's configuration file does not exist. The affected
2429 * The client did not load the hash functions from the SIM
2430 modules at all. Added support for this. Affected file is
2431 silc/clientconfig.c.
2433 * When decoding public key with silc_pkcs_public_key_decode, check
2434 the supported algorithm only if PKCS are registered. Affected
2435 file lib/silccrypt/silcpkcs.c. The same was done with the
2436 silc_pkcs_private_key_decode.
2438 * Fixed the SILC List routines to keep the list always in order.
2439 It used to change the list's order when traversing the list but
2440 not it preserves the order. Affected file lib/trq/silclist.h.
2442 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Added the client library to use the SilcSocketConnection's
2445 reference counter (by silc_socket_dup) to prevent the bug that
2446 the socket object may be freed underneath async operation.
2448 * The name resolv library checking fixes in the configure.in.pre.
2451 * Created new version of the protocol drafts for future
2452 development. The -03 drafts are the ones that will be changed
2453 in the trunk now and the -02 will remain as they are.
2455 * Send list of CUMODE notifys to the router when announcing
2456 the channel users to the router. Affected file silcd/server.c.
2457 If the router receiving channel founder CUMODE for a channel
2458 that already has channel founder it will send CUMODE notify
2459 to the sender to remove the channel founder rights from the
2460 announced client. Affected file silcd/packet_receive.c.
2462 * The CUMODE notify may now use Server ID as well as the entity
2463 who changes the mode. Updated protocool specs.
2465 * Updated INSTALL and README files.
2467 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * New web pages in the http://silc.pspt.fi. The pages was
2474 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2476 * Implemented the [DenyConnectin] config section in the server.
2477 Added silc_server_config_denied_conn to check whether incoming
2478 connection is denied. Affected file silcd/serverconfig.[ch].
2480 * Do not check the ports when checking the incoming configuration
2481 data if the port is 0, meaning any. Affected file is
2482 silcd/serverconfig.c.
2484 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Fixed buffer overflow in silc_string_compare in the file
2487 lib/silcutil/silcutil.c.
2489 * Fixed double free in silc_server_command_leave in the file
2492 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2494 * Fixed the version checking in the server. Affected file is
2497 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2499 * Fixed the configuration data fetching when accepting new
2500 connections in the server. Affected file silcd/server.c.
2502 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2504 * Added `sender_entry' argument to the function
2505 silc_server_packet_relay_to_channel so that we can check
2506 whether some destination actually belongs to the same route
2507 the sender belongs (ie, we must not resend the packet to the
2508 sender). Affected file silcd/packet_send.[ch].
2510 * Added `servername' field to the SilcClientEntry in the server
2511 to hold the name of the server where client is from. Affected
2512 file is silcd/idlist.h.
2514 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Moved the channel message encrypting in the router betwen
2517 router connections from silc_server_channel_message to the
2518 silc_server_packet_relay_to_channel since we want to check
2519 whether we have anybody channel before encrypting anything.
2520 Affected files silcd/packet_[receive/send].c.
2522 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Fixed the [AdminConnection] server config section to support
2525 multiple entries. Affected file silcd/serverconfig.c.
2527 * Added support into the server to check the validity of the
2528 incoming connection before executing any KE or authentication
2531 * The connection configuration is now saved to the KE and
2532 connection auth protocol contexts and not fetched anymore in
2533 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2535 * The local hosts listenning address and port is also resolved
2536 now when starting the server. We want to have the socket object
2537 to include the real address and port for the listener. Added
2538 new function silc_net_check_local_by_sock into the files
2539 lib/silcutil/silcnet.[ch].
2541 * Fixed a broadcast bug in server -> do not broadcast if we
2544 * Fixed a routing bug. Do not route broadcast packets ever.
2545 Broadcast packets must be processed always and not routed since
2546 they may be destined to some other host than yourself and thus
2547 would get routed without no good reason. Affected file is
2550 * Added function silc_server_config_is_primary_route to check
2551 whether primary router connection has been configured (a router
2552 configuration that we are initiating). If there is not, we
2553 will assume that there is only two routers in the SILC network
2554 and we will use the incoming router connection as our primary
2555 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2557 * Changed the order of the broadcasting. Broadcast _after_ the
2558 packet has been processed not before. Affected file is
2561 * Fixed a [ClientConnection] parsing bug. The port was never
2562 parsed correctly thus resulting to port 0. Affected file
2563 silcd/serverconfig.c.
2565 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2566 argument and did not set the broadcast packet flag. Affected
2567 file silcd/packet_send.c. Fixed same bug in the function
2568 silc_server_send_notify as well.
2570 * If we receive NEW_ID packet for our own ID in the server, ignore
2573 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Removed the nickname from the Private Message Payload.
2578 Updated the code and the protocol specs.
2580 * Updated protocol specs for submitting to the IETF.
2582 * Tweaked the Random Number Generator a bit. Affected file
2583 lib/silccrypt/silcrng.c. Exported a new function
2584 silc_rng_[global]_add_noise which can be used to add more
2587 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Do not parse packets with different timeout when protocol
2590 is active -> may cause problem with rekey. Affected file
2593 * When server receives signoff notify it must not create
2594 new channel key if the client is on any channels since the
2595 sender of the signoff notify will create it.
2597 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Added printing of error messages during SKE protocol from the
2600 failure packet sent by server during SKE. Affected file
2603 * Removed the client's failure_callback handling with timeout
2604 and handle it immediately when received.
2606 * The SKE library returned wrong type in SUCCESS and FAILURE
2607 packets. They must be 32 bit MSB not 16 bit MSB.
2609 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Ok, rewrote the logic of the re-key and now it seems to work.
2612 I tested it on high traffic with frequent re-keys without
2613 problems. Added hmac_receive (and renamed hmac to hmac_send)
2614 in SilcClientConnection in lib/silcclient/client.h and
2615 in SilcIDListData in silcd/idlist.h. Also, removed the
2616 SilcPacketParserContext's cipher and hmac fields as they are
2617 not needed anymore and actually caused some problems when
2618 the ciphers and hmac's changed underneath the packet parser.
2620 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * If re-key protocol is active then process the incoming packets
2623 synchronously since we must assure that icoming packets encrypted
2624 with the old key is processed before the new keys is set to
2625 use. This is true other packets than for REKEY packets.
2626 Affected file silcd/server.c. The same was done to client library
2627 as well, affected file lib/silcclient/client.c.
2629 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2631 * Fixed bug in client and server to accept the force send if
2632 the packet is send from silc_[server/client]_packet_process
2633 function. Otherwise the packets are never delivered, oops.
2635 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Disable force sending of packets when REKEY protocol is active.
2638 We must assure that no packet is sent directly when rekey is
2639 performed. All packets must be sent through packet queue.
2640 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2641 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2642 function is silc_[server/client]_packet_send_real to check
2645 * Replaced the SIM paths from example config files to
2646 /usr/local/modules. Also, make install creates now
2647 /usr/local/silc/logs directory to hold all the SILC server
2650 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Made the configure.in.pre work on Solaris. Patch by salo.
2654 * Made all ciphers compatible with non-x86 machines. Defined
2655 CBC mode macros into lib/silccrypt/ciphers_def.h.
2657 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Fixed the make install.
2661 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * When MAC computation fails the silc_packet_decrypt returned 0
2664 even though it was supposed to return -1. Fixed this. The
2665 affected file is lib/silccore/silcpacket.c.
2667 * Do not replace the config files in /etc/silc (in make install)
2668 if they already exist. Affected file ./Makefile.am.
2670 * Do not send re-key packets immediately but through packet queue.
2671 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2673 * Changed silc_net_check_host_by_sock to return FALSE if the
2674 IP/DNS could not be resolved. Though, it returns the IP address
2675 now even if it could not resolve it (but returns also FALSE).
2676 Affected file lib/silcutil/silcnet.[ch].
2678 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Added silc_pkcs_decode_identifier to decode the public key's
2681 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2682 Added also silc_pkcs_free_identifier. Added also new context
2683 SilcPublicKeyIdentifier.
2685 * Added -S option to the silc client. It is used to dump the
2686 contents of the specified public key file.
2688 * Changed the PKCS api to return the public key length when
2689 setting the public key.
2691 * Fixed a fatal bug in the public and private key file loading.
2692 Affected file lib/silccrypt/silcpkcs.c.
2694 * Execute the packet parsing for client with zero (0) timeout
2695 if the protocol is active. Affected file silcd/server.c.
2697 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2699 * Made the key generation options to the silcd program. Added
2700 -C option, equivalent to client's option.
2702 * Added new [ServerKeys] config section to the server. It
2703 configures the server's public and private key.
2705 * Defined generic Public Key Payload into the protocol
2706 specification to send specific type of public keys and
2709 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2710 public key or certificate.
2712 * Implemented the GETKEY command to the server and to the
2713 client library and on user interface.
2715 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2717 * Made preliminary `make install' work.
2719 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2721 * Added SilcServerRekey context into silcd/idlist.h.
2723 * Added the PFS support as defined in the specification to the
2724 SKE protocol. Affected files lib/silcske/*.c.
2726 * Added `ske_group' field to the SilcServerRekey context to hold
2727 the number of the SKE group that is used with PFS in re-key.
2728 Affected file silcd/idlist.h.
2730 * Added PFS re-key support to the server. Affected file is
2733 * Added silc_protocol_cancel to cancel execution of the next
2734 state of the protocol. Affected file is
2735 lib/silccore/silcprotocol.[ch].
2737 * Added the re-key support with and without PFS to the client
2738 library. Re-key is performed once in an hour, by default.
2740 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2741 Added silc_client_rekey_callback and silc_client_rekey_final.
2742 Affected files are lib/silcclient/protocol.[ch] and
2743 lib/silcclient/client.[ch].
2745 * Removed the `hmac_key' and `hmac_key_len' fields from the
2746 SilcClientConnection structure; not needed. Affected file is
2747 lib/silcclient/client.h.
2751 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2753 * Do not ask whether user wants to use the negotiated private key
2754 for private messages, just use it. Affected file is
2755 silc/local_command.c.
2757 * Added `send_enc_key' and `enc_key_len' fields to the
2758 SilcIDListData structure since they are needed in the re-key
2759 phase. Affected file is silcd/idlist.[ch].
2761 * Implemented the simple re-key protocol into the server.
2762 Affected files silcd/server.c and silcd/protocol.[ch]. The
2763 re-key will be performed once in an hour, by default.
2765 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2766 Added silc_server_rekey, silc_server_rekey_callback and
2767 silc_server_rekey_final.
2769 * Removed Tunneled flag from the protocol. Updated the code
2770 and the specifications.
2772 * Adde `pfs' field to the SilcIDListData to indicate whether
2773 the PFS is to be performed in the re-key. Affected file is
2776 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2779 int64 of at least the xintXX size. If void * is less that 4
2780 bytes uint32 * will be used. Defined bool as boolean.
2782 * Changed _ALL_ unsigned long and unsigned int to uint32,
2783 unsgined short to uint16 in the source tree.
2785 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2786 not handle clients that has entry->data.registered == FALSE.
2787 They are not in the network anymore. Affected file is
2790 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Implemented the sending of the SERVER_SIGNOFF notify in the
2793 server. Affected file is silcd/server.c.
2795 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2796 Added also silc_notify_payload_encode_args into the
2797 lib/silccore/silcnotify.[ch].
2799 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2800 Affected file silcd/packet_receive.c.
2802 * Implemented the SERVER_SIGNOFF notify handling in the client
2803 library. Affected file lib/silcclient/client_notify.c. Also,
2804 implemnted the printing of the SERVER_SIGNOFF info to the
2805 application. Affected file silc/client_ops.c.
2807 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2808 if the deleting was successful. Affected file silcd/idlist.[ch].
2810 * Added support for public key authentication in the connection
2811 authentication protocol in the client library. Affected file
2812 lib/silcclient/protocol.c.
2814 * Changed the server's silc_idlist_get_clients_by_* interface
2815 to support already allocated array so that new entries may be
2816 added to pre-allocated array. Affected file silcd/idlist.[ch].
2817 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2818 and command replies.
2820 * All command reply functions in the server now calls the
2821 pending command callback even if error occured. This way the
2822 error will be delivered to the client as well. Affected files
2823 silcd/command.c and silcd/command_reply.c.
2825 * Fixed INFO command to return local server's info if no server
2826 was provided. Affected file lib/silcclient/command.c.
2828 * Removed RESTART command for good. Updated the code and the
2831 * Rewrote parts of the task system. It is a bit simpler now.
2832 Removed unsued task priorities. The affected files are
2833 lib/silcutil/silctask.[ch].
2835 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Moved the USERS printing from the library to the application.
2838 Affected files lib/silcclient/command.c and silc/client_ops.c.
2840 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2844 * Added channel key re-key support. The re-key is perfomed
2845 only by the router and is done once in an hour. Added `rekey'
2846 field to the SilcChannelEntry in the server. Affected files
2847 silcd/server.c and silcd/idlist.h.
2849 * Added silc_task_unregister_by_context into the file
2850 lib/silcutil/silctask.[ch].
2852 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Added SILC_UMODE_GONE mode to indicate when the client is not
2855 present in the SILC network. Added also support to the local
2856 command AWAY that will set this mode. Added support of showing
2857 "xxx is gone" in WHOIS command. The USERS command shows the
2858 gone status as well.
2860 * Fixed setting server and router operator privileges in the
2861 server's UMODE command. Affected file silcd/command.c.
2863 * Merged the SKE KE1 and KE2 payloads into one payload. The
2864 new KE payload is equivalent to the old KE2 payload.
2866 Cleaned up the SKE Start Payload parsing. It now uses the
2867 simple buffer unformatting to do the parsing. A lot faster
2870 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2871 to the SKE that is used to indicate whether both of the SKE
2872 parties should perform authentication. By default only the
2873 responder performs authentication. By setting this flag also
2874 the initiator must do authentication. By default it is unset
2875 since in normal SKE case, client to server connection, only
2876 the responder should do authentication. When doing SKE between
2877 two clients both should perform authentication. Updated the
2878 code and the protocol specs.
2880 * A little fix to IDENTIFY command in the server. Search the
2881 client first by hash not nickname. Affected file is
2884 * Fixed the silc_client_close_connection to support closing
2885 the client to client connections wihtout deleting too much
2886 data. Affected file lib/silcclient/client.c.
2888 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2889 are received if protocol used to be active but is not anymore
2890 the application would crash due to NULL pointer dereference.
2891 Affected files silcd/server.c and lib/silcclient/client.c.
2893 * Added `hash' field to the SilcClientConnection to include
2894 the hash function negotiated in the SKE protocol.
2896 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2897 to set the channel founder authentication data. A client can
2898 claim the founder rights later by providing the authentication
2899 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2900 This way the channel founder can regain the channel founder
2901 privileges even it is left the channel. This works only on
2902 local server and the client must be connected to the same
2903 server to be able to regain the founder rights. Updated the
2904 protocol specs accordingly.
2906 Added support to the CMODE command in the client to set the
2907 founder auth data. Read the README to see how to set it.
2909 Added support to the CUMODE command to claim the founder
2910 rights. Read the README to see how to do it.
2912 Added support for the founder authentication to the Channel
2913 Entry in the server. Affected file silcd/idlist.h.
2915 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2916 server's CMODE command. Affected file silcd/command.c.
2918 * Added the following new functions into lib/silccore/silcauth.[ch]:
2919 silc_auth_get_method and silc_auth_get_data.
2921 * The server now saves the remote hosts public key to the
2922 SilcIDListData pointer. Affected file silcd/protocol.c.
2924 * The normal server now does not remove the channel entry from
2925 the cache if the founder authentication data is set. It used
2926 to remove it if the founder was the last one on the channel on
2927 the server and left the channel. The auth data is saved and
2928 if the channel is re-joined later the old entry is used with
2929 the old auth data. Affected files silcd/command_reply.c and
2932 * Removed the `pkcs' field from the SilcIDListData structure
2933 in the server; it is not used. Affected file silcd/idlist.h.
2935 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Fixed packet processing on slow links. Partial packets were
2938 never re-processed because the incoming data buffer was cleared
2939 by the application. Application must not directly clear the
2940 sock->inbuf, the packet processing routines handle it. Fixed
2941 this in client library and in server.
2943 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Fixed the WHOIS and IDENTIFY send reply function to really
2946 check whether to send list or just one entry. Affected file
2949 * Cleaned up the LEAVE command's channel key distribution. The
2950 affected file silcd/command.c.
2952 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2953 can enforce the channel mode as well. In that case the ID
2954 includes the ID of the server. The code now enforces the
2955 mode change if the router have different mode than the server.
2957 * The notify client operation with CMODE_CHANGE notify can now
2958 return NULL client_entry pointer if the CMODE was not changed
2959 by client. Application must check for this.
2961 * Added <Server ID> argument to INFO command to support server
2962 info fetching by Server ID.
2964 * Added silc_server_announce_get_channel_users to get assembled
2965 packets of channel users of the specified channel. Affected
2966 file silcd/server.[ch].
2968 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2969 was freed underneath the ID Cache.
2971 * Re-announce clients when the server received CHANNEL_CHANGE
2972 notify from the router. Affected file silcd/packet_send.c.
2974 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2977 crashed since it did not handle the fact that there is no cipher
2978 called "3" and didn't check the error condition. Now fixed.
2980 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2981 flag. It can be used to send message requests.
2983 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2985 * Implemented the RESTART command in the client.
2987 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2988 notice type messages. Added notice printing to the user
2991 * The channel keys are not re-generated if the channel's mode
2992 is PRIVKEY, ie private key on the channel exists. Affected
2993 files silcd/server.c and silcd/command.c.
2995 * Fixed a little bug in channel message delivery when channel
2996 private keys are set in the server. Affected file is
2997 silcd/packet_send.c.
2999 * Changed the setting on channel->on_channel = TRUE from the
3000 silc_client_save_channel_key to the JOIN command reply. The
3001 key payload is not received if the private channel key is set.
3002 Affected file lib/silcclient/command_reply.c and the
3003 lib/silcclient/client_channel.c.
3005 * When the CMODE_CHANGE notify is sent and the channel private
3006 key mode is removed the channel key must be re-generated in
3007 other cells as well. Added this support for the router in the
3008 silcd/packet_receive.c.
3010 * Added new local command NOTICE to send notice message on
3011 channel. Affected file silc/local_command.[ch].
3013 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Added new local command ME to the client. It is used to send
3016 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3017 some action. Affected file silc/local_command.[ch].
3019 * Changed channel_message and private_message client operations
3020 to deliver the message flags to the application. Added also
3021 the `flags' arguments to the silc_client_send_channel_message
3022 and silc_client_send_private_message functions. Affected file
3025 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Redefined the Private Message Payload to support private message
3028 keys and to support the new private message flags. Updated
3029 the protocol specs. Flags makes it possible to have for example
3030 CTCP style messages.
3032 * Added new type SilcPrivateMessagePayload and defined an API
3033 for it in the lib/silcclient/silcprivate.[ch].
3035 * Tested private message private keys successfully. Tested the
3036 private message key set, unset and list commands with the new
3039 * Redefined the Channel Message Payload to include the channel
3040 message flags (equal with private message flags) to support
3041 for example CTCP style messages.
3043 * Defined some of the message (for channel and private message)
3044 flags. Updated the protocol specs and added the flags to the
3045 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3047 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3049 * Added SilcKeyAgreementStatus type to the key agreement routines
3050 to indicate the current status and error if one occured.
3051 The status types are defined in the lib/silcclient/silcapi.h.
3053 * Added new local command KEY that is used to set and unset private
3054 keys for channels, set and unset private keys for private messages
3055 with remote clients and to send key agreement requests and
3056 negotiate the key agreement protocol with remote client. The
3057 key agreement is supported only to negotiate private message keys,
3058 it currently cannot be used to negotiate private keys for channels,
3059 as it is not convenient for that purpose.
3061 * Fixed a minor pending callback setting bug in the function
3062 silc_client_get_client_by_id_resolve, now the function works.
3063 Affected file lib/silcclient/idlist.c.
3065 * Added function silc_net_get_local_port to get local bound
3066 port by socket. Added to lib/silcutil/silcnet.[ch].
3068 * Added `sockets' and `sockets_count' fields to the SilcClient
3069 object. They hold the sockets of the listenning sockets in
3070 the client. Listenning sockets may be for example the key
3071 agreement server. Affected file lib/silcclient/client.[ch].
3072 Added functions the silc_client_add_socket and the
3073 silc_client_del_socket. They are exported to the application
3076 * Added ~./silc/clientkeys to support other client's public keys.
3078 * Renamed verify_server_key client operation to verify_public_key
3079 and added one argument to indicate the type of the connection
3080 (server, client etc.).
3082 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Added silc_server_connection_auth_request to handle the
3085 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3086 silcd/packet_receive.[ch].
3088 * Added silc_server_send_connection_auth_request into the
3089 silcd/packet_send.c to send the connection auth request packet.
3091 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3094 * Fixed the public key authentication in responder side in the
3095 server. The `auth_data' pointer includes the SilcPublicKey
3096 not the path to the public key. Affected file silcd/protocol.c.
3098 * Implemented the public key authentication in the initiator side
3099 in the server. Affected file silcd/protocol.c.
3101 * Removed the [RedirectClient] config section from the server
3102 configuration. Is not needed and I don't want to implement it.
3104 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Cleaned up the CMODE command in the server. It now works
3107 correctly and supports all the modes defined in the protocol.
3108 Affected file is silcd/command.c.
3110 * Added `hmac_name' field to the SilcChannelEntry in the server
3111 to hold the default HMAC of the channel. It can be set when
3112 creating the channel (with JOIN command). Affected files
3115 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3116 type to indicate the change of the current cipher and hmac
3117 on the channel. Client can safely ignore the <cipher> argument
3118 (if it chooses to do so) since the CHANNEL_KEY packet will
3119 force the channel key change anyway. The <hmac> argument is
3120 important since the client is responsible of setting the new
3121 HMAC and the hmac key into use.
3123 * Fixed the CMODE command in the client library as well.
3125 * Tested CMODE command in router environment successfully.
3127 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3129 * Show the version of the remote client (or server) when connecting
3130 to the server. It is logged to the log file. Affected file
3131 is silcd/protocol.c.
3133 * Fixed the KILLED notify handling in the client library. The
3134 client must be removed from all channels when receiving the
3137 Also, do not remove the client entry when giving the KILL
3138 command but when the KILLED notify is received.
3140 * Removed silc_idlist_find_client_by_nickname from the server.
3141 Not needed anymore. Affected files silcd/idlist.[ch].
3143 * Implemented the CHANNEL_CHANGE notify type handling to the
3144 server. Affected file silcd/server.c.
3148 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3150 * Added silc_server_send_notify_invite to send the INVITE
3151 notify between routers.
3153 * Implemented the INVITE command correctly to the server.
3155 * Implemented the INVITE notify type handling in the server.
3157 * Implemented the INVITE command to the client library and on the
3160 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Added function silc_server_get_client_resolve to find the
3163 client entry by ID from all ID lists and then resolve it
3164 (using WHOIS) if it cannot be found. Affected file is
3167 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3169 * Implemented the BAN command to the client library.
3171 * The JOIN command in the server now checks the invite list
3174 * Changed the silc_command_reply_payload_encode_va and the
3175 silc_command_payload_encode_va to support that if argument is
3176 NULL it ignores and checks the next argument. Affected file
3177 lib/silccore/silccommand.c.
3179 * Added silc_server_send_notify_ban to send the BAN notify
3180 type between routers.
3182 * Chaned the silc_notify_payload_encode to support that if
3183 argument is NULL it ignores and checks the next argument.
3184 Affected file lib/silccore/silcnotify.c.
3186 * Tested ban lists in router environment successfully.
3188 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Implemented BAN command to the server, in silcd/command.[ch].
3192 * Removed the BAN and INVITE_LIST modes from the CMODE command
3195 * Added function silc_string_match to regex match two strings.
3196 Affected files lib/silcutil/silcutil.[ch].
3198 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Redefined parts of the SilcChannelEntry in the server to support
3201 the new ban and invite lists.
3203 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Redefined the INVITE command. The same command can be used to
3206 invite individuals to the channel but also to manage the invite
3207 list of the channel (to add to and remove from the invite list).
3208 Updated the protocol specs.
3210 * Added new command SILC_COMMAND_BAN that can be used to manage
3211 the ban list of the channel. Updated the protocol specs.
3213 * Removed the channel modes: the SILC_CMODE_BAN and the
3214 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3215 in the CMODE command. The equivalent features are now available
3216 using INVITE and BAN commands. Updated the protocol specs.
3218 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3219 in the network about change in the current ban list. The notify
3220 type is not used by the client.
3222 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3223 support the invite lists.
3225 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3227 * Added new function silc_string_regexify that converts string
3228 including wildcard characters into regex string that can
3229 be used by the GNU regex library. Added into the file
3230 lib/silcutil/silcutil.[ch].
3232 Added silc_string_regex_combine to combine to regex strings
3233 into one so that they can be used as one regex string by
3234 the GNU regex library. Added into the file
3235 lib/silcutil/silcutil.[ch].
3237 Added silc_string_regex_match to match two strings. It returns
3238 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3240 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Imported GNU regex to the soruce tree into lib/contrib.
3243 Fixed some compiler warning from the regex.c.
3245 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3247 * Fixed MOTD command in the server to work in router environment.
3249 * Fixed the MOTD command in the client library to support
3250 the server argument in the command.
3252 * Added `nickname_len' argument to the silc_idlist_add_client
3253 in the server, as the `nickname' argument may be binary data
3256 * Added silc_idlist_get_channels to return all channels from
3259 * Implemented LIST command to the server. Affected file is
3262 * Implemented the LIST command to the client library and on the
3265 * Added [<user count>] argument to the LIST command reply.
3266 With private channels the user count is not shown.
3268 * Updated TODO and README.
3270 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * The client entry's data.registered must be TRUE even with
3273 global client entry on global client list. The data.registered
3274 is used to check whether the client is anymore in the network,
3275 for example with WHOWAS command so it must be valid.
3277 * Fixed the WHOWAS command in the server. It now actually works
3278 in router environment. Added function into silcd/command_reply.c
3279 silc_server_command_reply_whowas_save.
3281 * Added silc_idlist_purge function to the silcd/idlist.c
3282 to periodically purge the ID Cache.
3284 * Fixed INFO command in the server. It works now in router
3285 environment. Added <server name> argument to the INFO command
3286 reply. Updated the protocol specs.
3288 * Fixed minor bug in silc_idcache_purge to not purge if the
3289 expire value is zero.
3291 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3292 they were buggy because of the WHOWAS information.
3294 * Fixed local command MSG to handle the async resolving of
3295 the remote client properly. It used to fail the first MSG.
3296 Affected file silc/local_command.c.
3298 * Added `data_len' field to SilcIDCache context.
3300 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Update TODO. Todo in commands in the server.
3304 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3306 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3307 used by routers as broadcast packet to inform other routers
3308 about the changed user mode.
3310 Implemented the notify handling in the server. Affected file is
3311 silcd/packet_receive.c. Added the function
3312 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3314 * Added new generic Channel Payload and deprecated the New Channel
3315 Payload. The New Channel Payload is now the generic Channel
3318 * Added new argument `mode' to the silc_server_send_new_channel
3319 as it is required in the Channel Payload now.
3321 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3322 and created a new and real SilChannelPayload to represent the
3323 new generic Channel Payload. Implemented the encode/decode
3324 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3326 * Added silc_server_get_client_channel_list to return the list
3327 of channels the client has joined for WHOIS command reply.
3328 Affected file silcd/server.[ch].
3330 * Implemented the channel list sending in the WHOIS command reply
3331 in server and in the client.
3333 Implemented the channel list displaying on the user interface
3334 as well. Affected file silc/client_ops.c.
3336 * Added silc_channel_payload_parse_list to parse list of Channel
3337 Payloads. It returns SilcDList list of SilcChannelPayloads.
3338 Client for example can use this function to parse the list of
3339 channels it receives in the WHOIS command reply. The caller
3340 must free the list by calling silc_channel_payload_list_free.
3341 Affected files lib/silccore/silcchannel.[ch].
3343 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Added one new argument <user mode> to the WHOIS command reply
3346 to return the mode of the user in SILC. Updated the protocol
3349 Implemented it to the server and client.
3351 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3353 * Fixed the mode printing on the user interface on joining.
3354 Affected file silc/client_ops.c.
3356 * Implemented the UMODE command and user modes in general to the
3357 client library and to the user interface.
3359 * Implemented the UMODE command to the server.
3361 * The server now sends UNKNOWN_COMMAND error status if client sends
3362 unknown command. Affected file silcd/command.c.
3364 * All server commands now handle the command identifier the right
3365 way when sending the command reply to the client. The client can
3366 use to identify the command replies with the identifier.
3368 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Added silc_server_get_client_route to resolve the route to
3371 the client indicated by the client ID. Affected file is
3374 * Added silc_server_relay_packet as general function to relay
3375 packet to arbitrary destination. This deprecates functions
3376 like _send_private_message_key, _relay_notify etc. Affected
3377 file is silcd/packet_send.[ch].
3379 Removed silc_server_send_key_agreement,
3380 silc_server_send_private_message_key and
3381 silc_server_packet_relay_notify functions from the file
3382 silcd/packet_send.[ch].
3386 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3387 server. Affected file silcd/packet_receive.[ch].
3389 * Implemented the KILL command to the client. Implemented the
3390 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3391 Affected files lib/silcclient/command[_reply].c and
3392 lib/silcclient/client_notify.c. Implemented the KILL notify
3393 printing in the user inteface.
3395 * Fixed a lot silc_parse_nick memory leaks from the client
3396 library in the file lib/silcclient/command.c.
3398 * Changed the silc_server_send_notify_on_channels's `sender'
3399 argument from SilcSocketConnection to SilcClientEntry to
3400 check the sender as entry and not as connection object and not
3401 to send to the client provided as argument. The affected file
3402 is silcd/packet_send.[ch].
3404 * The notify packets that are destined directly to the client used
3405 to not to be processed by the server. Now changed that and the
3406 server processes all notify packets. After relaying the packet
3407 to the client the notify packet is processed in the server.
3409 * The silc_server_free_client_data now checks whether there is
3410 pending outgoing traffic for the client and purges the data to
3411 the network before removing the client entry.
3413 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3416 an client is killed from the SILC Network. Updated the protocol
3419 Added new function silc_server_send_notify_killed to the
3420 silcd/packet_send.[ch].
3422 * Added function silc_server_packet_relay_notify to relay notify
3423 packets that are destined directly to a client. In this case
3424 the server does not process the notify packets but merely relays
3425 it to the client. Affected file silcd/packet_send.[ch].
3427 Added also silc_server_packet_process_relay_notify to check
3428 whereto relay the notify. Affected file is
3429 silcd/packet_receive.[ch].
3431 * Implemented the KILL command to the server.
3435 * Added the backup schema desgined last fall to the protocol
3436 specs for everyone to see. The specification is in the
3437 *-spec-xx.txt draft and the packet type definitions for the
3438 backup routers is in *-pp-xx.txt draft. Thusly, added also
3439 new packet type SILC_PACKET_CELL_ROUTERS.
3441 * A big security problem in the implementation discovered. The
3442 signoff of an client did not cause new channel key generation
3443 which it of course should've done. The channel keys must be
3444 always re-generated when client leaves (or signoffs) the channel.
3445 The silc_server_remove_from_channels funtion now handles
3446 the channel key re-generation.
3448 * Added `sender' argument to the silc_server_send_notify_on_channels
3449 to not to send the client provided as argument. Affected file
3450 silcd/packet_send.[ch].
3452 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Implemented OPER and SILCOPER commands into the server and
3457 * Added silc_auth_verify and silc_auth_verify_data to verify
3458 the authentication directly from the authentication payload.
3459 It supports verifying both passphrase and public key based
3460 authentication. Affected file lib/silccore/silcauth.[ch].
3462 * Added `hash' field to the SilcIDListData structure. It is the
3463 hash negotiated in the SKE protocol. Affected file is
3466 * Slight redesigning of the SilcAuthPayload handling routines.
3467 Do not send SilcPKCS but SilcPublicKey as argument.
3469 * Implemented the public key authentication support to the
3470 serverconfig. The public key is loaded from the provided path
3471 and saved as authentication data to void * pointer. Thus,
3472 changed the unsigned char *auth_data to void *auth_data;
3474 * Fixed SHUTDOWN command to send the reply before the server
3475 is shutdown. :) Affected file silcd/command.c.
3477 * Fixed fatal bug in CONNECT command. The hostname was invalid
3478 memory and server crashed. Affected file silcd/command.c.
3480 * Fixed fatal bug in CLOSE command. The server_entry became
3481 invalid but was referenced later in the command. Affected file
3484 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Fixed fatal bug in failure packet handling. Server ignored
3487 the failure and thus crashed when it came.
3491 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3493 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3494 that the command may be executed only once in (about) 2 seconds.
3495 The old SILC_CF_LAG flag is same but allows command bursts up
3496 to five before limiting.
3498 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3499 server code. Various commands now includes the CF_LAG_STRICT
3500 flag to disallow any kind of miss-use of the command.
3502 * Fixed the silc_buffer_unformat to not to allocate any data
3503 if the length of the data is zero. It used to allocate the
3504 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3506 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Changed the format of AdminConnection configuration section
3509 in the server. Added username of the admin to the format.
3510 Affected files silcd/serverconfig.[ch].
3512 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3513 to return admin configuration data by host, username and/or
3516 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3518 * Implemented WHOWAS command to the server. Added the functions:
3520 silc_server_command_whowas_parse,
3521 silc_server_command_whowas_send_reply,
3522 silc_server_command_whowas_from_client and
3523 silc_server_command_whowas_from_server
3525 * Added <Client ID> argument to the WHOWAS command reply. Updated
3526 the protocol specs accordingly.
3528 * Implemented WHOWAS command and command_reply to the client
3531 Implemented the WHOWAS printing on the user interface.
3533 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3535 * Added new argument to the WHOWAS command reply, the real name.
3536 It is an optional argument. Updated the protocol specs.
3538 * Added SilcIDCacheDestructor callback that is registered when
3539 the SilcIDCache is allocated. The callback is called when
3540 an cache entry in the ID Cache expires, or is purged from the
3541 cache. Added into lib/silccore/idcache.[ch].
3543 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3544 to destruct the client entries when the cache entry expires.
3545 Other ID Cache's in server and in the client library ignores
3548 * If the ID Cache entry's `expire' field is zero then the entry
3549 never expires. Added boolean `expire' argument to the
3550 silc_idcache_add function in the lib/silccore/idcache.[ch].
3551 If it is TRUE the default expiry value is used.
3553 * Added silc_server_free_client_data_timeout that is registered
3554 when client disconnects. By default for 5 minutes we preserve
3555 the client entry for history - for WHOWAS command.
3557 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3559 * Added support to the server to enforce that commands are not
3560 executed more than once in 2 seconds. If server receives
3561 commands from client more frequently, timeout is registered
3562 to process the commands. Affected file silcd/command.c.
3563 Added new function silc_server_command_process_timeout.
3565 * Changed NICK_NOTIFY handling in client library to check that
3566 if the client's nickname was changed, so there is no need to
3567 resolve anything from the server.
3569 * Removed error printing from the WHOIS and IDENTIFY commands.
3570 If error occurs then it is ignored silently in the client library.
3571 The application, however, may map the received error to
3572 human readable error string. The application currently maps
3573 the NO_SUCH_NICKNAME error to string.
3575 * Made the command status message public to the application. Moved
3576 them from lib/silcclient/command_reply.c to
3577 lib/silcclient/command_reply.h. The application can map the
3578 received command status to the string with the
3579 silc_client_command_status_message function.
3581 * Added check to the server to check that client's ID is same
3582 as the Source ID in the packet the client sent. They must
3585 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Added dist-bzip hook to the Makefile.am to make bzip2
3588 compressed distributions.
3590 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3592 * Server now enforces the maximum length for the nickname and
3593 the channel as protocol specification dictates. 128 bytes for
3594 nickname and 256 bytes for channel name.
3596 * Moved the WHOIS printing to the application. The client libary
3597 does not print out the WHOIS information anymore, the application
3598 must do it. Renamed silc_client_command_reply_whois_print to
3599 the silc_client_command_reply_whois_save.
3601 The client's idle time is also sent to the application now, and
3602 the idle is shown on screen.
3604 * Added silc_client_command_reply_identify_save to save the
3605 received IDENTIFY entries.
3607 * Do not check for channel private keys in message sending and
3608 reception if the channel does not have the PRIVKEY mode set.
3609 Affected file lib/silclient/client_channel.c.
3611 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3614 just surfaced after chaning the JOIN procedure.
3616 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * Added silc_client_get_clients_by_list to get client entries
3619 from Client ID list, that is returned for example by JOIN
3620 and USERS command replies. The application should use this
3621 function for example when JOIN command reply is received to
3622 resolve the clients already on the channel (library does not
3623 do that anymore as USERS command reply is not used in the JOIN
3624 procedure anymore). Affected files lib/silcclient/silcapi.h and
3625 lib/silcclient/idlist.c.
3627 * JOIN command reply and USERS command reply returns now SilcBuffer
3628 pointers instead of unsigned char pointers when returning
3629 the client list and mode list.
3631 * Added <Client ID> argument to the JOIN command reply, mainly
3632 for the server to identify for which client the command was
3633 originally sent. Updated protocol specs accordingly.
3635 * Added SilcDlist private_key pointer to the SilcChannelEntry
3636 in the client to support the channel private keys. Affected
3637 file is lib/silcclient/idlist.h.
3639 * Added SilcChannelPrivateKey argument to the function
3640 silc_client_send_channel_message so that application can choose
3641 to use specific private ke if it wants to. If it is not provided,
3642 the normal channel key is used, unless private keys are set.
3643 In this case the first (key that was added first) is used
3644 as the encryption key.
3646 * Implemented the support for channel private key handling.
3647 Implemented the following functions:
3649 silc_client_add_channel_private_key,
3650 silc_client_del_channel_private_keys,
3651 silc_client_del_channel_private_key,
3652 silc_client_list_channel_private_keys and
3653 silc_client_free_channel_private_keys
3655 Affected file lib/silcclient/client_channel.c.
3657 * Added the support for the private keys in the channel message
3658 sending and encryption and in the message reception and
3659 decryption. Affected funtions are
3660 silc_client_send_channel_message and silc_client_channel_message.
3662 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Added SKE's key verify callback to the client library's
3665 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3667 * Removed the statement that server (or router) must send USERS
3668 command reply when joining to the channel so that the client
3669 knows who are on the channel. Instead, the client list and
3670 client's mode list is now sent in the JOIN command reply to the
3671 client who joined channel. This is better solution.
3673 * Added function silc_server_get_users_on_channel and function
3674 silc_server_save_users_on_channel to the silcd/server.[ch].
3676 * Removed function silc_server_command_send_users from the
3679 * Do not show topic on the client library anymore. The topic is
3680 sent in the command reply notify to the application and the
3681 application must show the topic now.
3683 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3685 * Added client searching by nickname hash into the IDENTIFY and
3686 WHOIS commands in the server as they were clearly missing from
3687 them. Affected file is silcd/command.c.
3689 * Fixed a bug in private message receiving in the client library.
3690 The remote ID was freed and it wasn't supposed, now it is
3693 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3695 * Minor fix to the channel payload; allocate the data area, as it
3696 needs to be of specific length.
3698 * If the key agreement port is zero then the operating
3699 system will define the bound port. Affected files are
3700 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3702 * Added new function silc_channel_payload_decrypt into the file
3703 lib/silccore/silcchannel.[ch].
3705 * Moved the channel message etc, check from silc_packet_decrypt
3706 to applications. The library calls now a generic
3707 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3708 when the packet is either normal or special. This was done to
3709 allow more wide range of checking that was not allowed when
3710 the code was in library. Now applications can do virtually any
3711 checks to the packet and return to the library the decision how
3712 the packet should be processed. Affected files are
3713 lib/silccore/silcpacket.[ch].
3715 Added silc_server_packet_decrypt_check to the server and
3716 silc_client_packet_decrypt_check to the client library.
3718 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3719 to send with specified source and destination information.
3721 * Channel message delivery between routers was broken after the
3722 channel key distribution was fixed earlier. The channel key
3723 was used be to distributed to other routers as well which is not
3724 allowed by the protocol. Now this is fixed and channel keys
3725 really are cell specific and the channel message delivery between
3726 routers comply with the protocol specification.
3728 * Fixed various commands in server to check also the global list
3729 for the channel entry and not just the local list. The affected
3730 file silcd/command.c.
3732 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added assert()s to buffer formatting and unformatting routines
3735 to assert (if --enable-debug) when error occurs. Affected
3736 file: lib/silcutil/silcbuffmt.c.
3738 * Changed to auto-reconnect to check whether the remote host is
3739 router and register the re-connect timeout if it is. It used
3740 to check that whether we are normal server, but router must do
3741 auto-reconnect with another router as well. Affected file
3744 * Removed the [<key len>] option from CMODE command as the cipher
3745 name decides the key length, nowadays. See the defined ciphers
3746 from the protocol specification.
3748 * Added [<hmac>] option to the CMODE command to define the HMAC
3749 for the channel. Added SILC_CMODE_HMAC channel mode.
3751 * Added [<hmac>] option for the JOIN command so that user can
3752 select which HMAC is used to compute the MACs of the channel
3755 * Added Hmac field to the Channel Message Payload. The integrity
3756 of plaintext channel messages are now protected by computing
3757 MAC of the message and attaching the MAC to the payload. The
3758 MAC is encrypted. Now, it is clear that this causes some
3759 overhead to the size of the packet but rationale for this is that
3760 now the receiver can verify whether the channel message decrypted
3761 correctly and also when private keys are set for the channel the
3762 receiver can decrypt the packet with several keys and check from
3763 the MAC which key decrypted the message correctly.
3765 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3766 lib/silccrypt/silccipher.[ch].
3768 * Added silc_hash_len to return the digest length into the
3769 lib/silcrypt/silchash.[ch].
3771 * Rewrote parts of Silc Channel Payload interface in the
3772 lib/silccore/silcchannel.[ch]. The encode function now also
3773 encrypts the packet and parse function decrypts it.
3775 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Fixed a minor formatting bug in the SKE's key material processing.
3778 It actually might have processed the keys wrong way resulting
3781 * Redefined the mandatory HMAC algorithms and added new algorithms.
3782 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3783 and hmac-md5 truncated to 96 bits. The mandatory is now
3784 hmac-sha1-96. Rest are optional (including the one that used
3785 to be mandatory). Rationale for this is that the truncated HMAC
3786 length is sufficient from security point of view and can actually
3787 make the attack against the HMAC harder. Also, the truncated
3788 HMAC causes less overhead to the packets. See the RFC2104 for
3791 * Added new [hmac] configuration section. The SKE used to use
3792 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3793 is of course wrong. The official names that must be proposed in
3794 the SKE are the ones defined in the protocol specification
3795 (hmac-sha1-96 for example). The user can configure any hmac
3796 using any hash function configured in the [hash] section. At
3797 least, the mandatory must be configured.
3799 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3801 * Added HMAC list to the SKE proposal list. It has now both
3802 hash algorithm list and HMAC list. This makes the protocol
3803 incompatible with previous versions. The SKE now seems to work
3804 the way it is supposed to work, for the first time actually.
3806 * Defined plain Hash algorithms to the protocol specification.
3809 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3811 * Implemented support for key agreement packets into the server.
3812 Added functions silc_server_key_agreement and
3813 silc_server_send_key_agreement. Other than these functions,
3814 server has nothing to do with this packet.
3816 * Added support for private message key packets into the server.
3817 Added functions silc_server_private_message_key and
3818 silc_server_send_private_message_key.
3822 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3823 called in the protocol's final callback instead in the END
3824 protocol state. This makes a little more sense and in the same
3825 time in client we can use the same protocol routines for normal
3826 key exchange and to key agreement packet handling as well.
3828 * Added to both client's and server's KE protocol context the
3829 SilcSKEKeyMaterial pointer to save the key material. We will
3830 bring the key material to the protocol's final callback by doing
3831 this. The final callback must free the key material.
3833 * Added SKE's packet_send callback into client's KE protocol
3834 context so that the caller can choose what packet sending function
3835 is used. This way we can use different packet sending when
3836 doing normal SKE when doing key agreement packet handling (in
3837 the key agreement packet handling we do not want to encrypt
3840 * Implemented the responder side of the key agreement routines
3841 in the client. The client can now bind to specified port and
3842 accept incoming key negotiation. The key material is passed
3843 to the application after the protocol is over.
3845 * Implemented the processing of incoming Key Agreement packet
3846 in the client. Added function silc_client_key_agreement to
3849 * Implemented the intiator side of the key agreement routines
3850 in the client. The client can now initiate key agreement with
3851 another remote client. The key material is passed to the
3852 application after the protocol is over.
3854 * Created client_keyagr.c to include all the key agreement
3857 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3858 SILC_TASK_CALLBACK except that it is not static.
3860 * Created client_notify.c and moved the Notify packet handling
3861 from the client.[ch] into that file.
3863 * Created client_prvmsg.c and moved all private message and
3864 private message key routines from the client.[ch] into that file.
3866 * Create client_channel.c and moved all channel message and
3867 channel private key routines from the client.[ch] into that file.
3869 * Changed silc_client_get_client_by_id_resolve to resolve with
3870 WHOIS command instead of IDENTIFY command, in the file
3871 lib/silclient/idlist.c.
3873 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3875 * Implemented the SKE's responder side to the Client library.
3877 * When FAILURE is received to the protocol do not trust it
3878 blindly. Register a timeout to wait whether the remote closes
3879 the connection as it should do it, only after that process the
3880 actual failure. This was changed to both client and server.
3882 * Added client_internal.h to include some of the structures
3883 there instead of client.h in lib/silcclient/.
3885 * Added function silc_task_unregister_by_callback to unregister
3886 timeouts by the callback function.
3888 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Some "Incomplete WHOIS info" errors has been appearing on the
3891 log files. Took away the entry->userinfo check from WHOIS
3892 reply sending. The entry->userinfo is now " " if client did not
3893 provide one. I thought this was fixed earlier but something
3894 is wrong still. Let's see if the error still appears.
3896 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3898 * Fixed a minor bug in the login when the channel key is
3899 re-generated in the server. It used to generate the key in
3900 wrong order and thus caused problems in the channel traffic.
3902 * Fixed a minor bug in channel key distsribution after
3903 KICK command. The key was not sent to the router even though
3906 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3908 * Added silc_ske_process_key_material_data as generic routine
3909 to process any key material as the SILC protocol dictates. The
3910 function is used by the actual SKE library but can be used by
3911 applications as well. This relates to the private message keys
3912 and the channel private keys since they must be processed the
3913 same way the normal SILC session keys. The protocol dictates
3914 this. Affected files: lib/silcske/silcske.[ch].
3916 Added also silc_ske_free_key_material to free the
3917 SilcSKEKeyMaterial structure.
3919 * Defined silc_cipher_set_key function to set the key for
3920 cipher without using the object's method function. The affected
3921 files: lib/silccrypt/silccipher.[ch].
3923 * Implemented silc silc_client_add_private_message_key,
3924 silc_client_add_private_message_key_ske,
3925 silc_client_del_private_message_key,
3926 silc_client_list_private_message_keys and
3927 silc_client_free_private_message_keys functions in the
3930 Added functions silc_client_send_private_message_key to send
3931 the Private Message Key payload and silc_client_private_message_key
3932 to handle incoming Private Message Key payload.
3934 * Added Cipher field to the Private Message Key payload to set
3935 the cipher to be used. If ignored, the default cipher defined
3936 in the SILC protocol (aes-256-cbc) is used.
3938 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Removed lib/silcclient/ops.h file.
3942 Redefined parts of the SILC Client Library API. Created new
3943 file silcapi.h that deprecates the ops.h file and defines the
3944 published Client Library API. Defined also private message key
3945 API and channel private key API into the file.
3947 This is the file that the application must include from the
3948 SILC Client Library. Other files need not be included by
3949 the application anymore.
3951 * Added new key_agreement client operation callback and also
3952 defined the Key Agreement library API for the application.
3954 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3956 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3957 is used by clients to request key negotiation between another
3958 client in the SILC network. If the negotiation is started it
3959 is performed using the SKE protocol. The result of the
3960 negotiation, the secret key material, can be used for example
3961 as private message key.
3963 Implemented the Key Agreement payload into the files
3964 lib/silccore/silauth.[ch].
3966 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Redefined ciphers for the SILC protocol. Added some new ciphers
3969 and defined the key lengths for the algorithms. Changed the
3970 code accordingly. The default key length is now 256 bits.
3972 * Fixed SKE key distribution function silc_ske_process_key_material
3973 when the key length is more than 128 bits. The default key
3974 length in SILC is now 256 bits.
3976 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3977 to indicate unsupported algorithm.
3979 * Renamed rijndael.c to aes.c and all functions as well.
3981 * Fixed a long standing channel key setting bug in client library.
3982 Weird that it has never surfaced before.
3984 * Fixed bug in channel deletion. If the entire channel is removed
3985 then it must also delete the references of the channel entry
3986 from the client's channel list as the client's channel entry and
3987 the channel's client entry share same memory.
3989 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Implemented CONNECT and SHUTDOWN commands in the client.
3993 * Implemented CLOSE command to the client.
3995 * Added the function silc_idlist_find_server_by_name into the
3996 files silcd/idlist.[ch].
3998 Added the function silc_idlist_find_server_by_conn into the
3999 files silcd/idlist.[ch].
4001 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * DIE command was renamed to SHUTDOWN. Updated the both code
4006 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4007 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4009 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4012 * Added function silc_server_create_connection function to create
4013 connection to remote router. My server implementation actually
4014 does not allow router to connect to normal server (it expects
4015 that normal server always initiates the connection to the router)
4016 so the CONNECT command is only good for connecting to another
4019 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4022 or some other client was kicked from the channel.
4024 Implemented the handling of the notify type to both client
4027 Implemented silc_server_send_notify_kicked to send the KICKED
4028 notify. It is used to send it to the server's primary router.
4030 * Implemented the KICK command into server and client.
4032 * Added `query' argument to the silc_idlist_get_client function
4033 to indicate whether to query the client from server or not if
4036 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4037 to indicate that the client is not channel founder.
4041 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Removed the rng context from SilcPacketContext structure and
4044 changed that the packet routine uses the Global RNG API.
4046 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4048 * Added support for quit message that client can "leave" on the
4049 channel when it quits the SILC. It is ditributed inside the
4050 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4052 Added silc_server_free_client_data that will take the
4053 signoff message as argument.
4055 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4057 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4059 * Updated parts of the protocol specification to keep it up
4062 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4065 payloads in one packet.
4067 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4068 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4069 use now the new List flag.
4071 * Also deprecated the following packet types: REPLACE_ID,
4072 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4074 * Added list support for Notify packet in server.
4076 * Added silc_server_send_notify_channel_change to send the
4077 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4078 the silc_server_send_replace_id.
4080 * Added silc_server_send_notify_nick_change to send the
4081 NICK_CHANGE notify type. Deprecates the function
4082 silc_server_send_replace_id.
4084 * Added silc_server_send_notify_join to send the JOIN notify type.
4085 Deprecates the function silc_server_send_new_channel_user.
4087 * Added silc_server_send_notify_leave to send LEAVE notify type.
4088 Deprecates the function silc_server_send_remove_channel_user.
4090 * Added silc_server_send_notify_cmode and
4091 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4092 types. Deprecates the silc_server_send_set_mode function.
4094 * Added SERVER_SIGNOFF notify type to indicate that server has
4095 quit. This means that all clients on the channel from that
4096 server will drop. This can be also used when netsplit happens.
4098 Deprecated REMOVE_ID packet type since it is not needed anymore
4101 Added silc_server_send_notify_server_signoff to send the
4102 SERVER_SIGNOFF notify type. Deprecates the function
4103 silc_server_send_remove_id.
4105 Added also silc_server_send_notify_signoff to send the
4106 SIGNOFF notify type.
4108 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4109 SILC protocol from this day on. Changed the protocol
4110 specification as well.
4112 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4113 notify type. It is used between routers to notify about
4114 topic changes on a channel.
4116 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4119 * Partly updated the protocol specification to comply with the
4120 changes now made. It is still though a bit outdated.
4122 * The JOIN notify type now takes one extra argument <Channel ID>.
4123 The packet used to be destined to the channel but now the
4124 JOIN type may be sent as list thus it is impossible to
4125 destine it to any specific channel. By adding this argument
4126 it is again possible.
4128 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added CREDITS file. The CHANGES and CREDITS file will appear
4131 in the distribution as well.
4133 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4135 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4136 types in the server's silcd/packet_receive.c.
4138 * Implemented CMODE and CUMODE to work in router environment.
4140 * Fixed minor encoding and decoding buglet from the
4141 lib/silccore/silcmode.c.
4143 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4146 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4148 * Changed all SilcConfigServer* and silc_config_server* to
4149 SilcServerConfig* and silc_server_config*, respectively.
4152 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Associated the ID (client or server ID) to the Authentication
4155 Payload to avoid any possibility of forging. Updated the
4156 protocol specification and the code accordingly.
4158 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * The RSA key length is now save to the RsaKey context in the
4161 key generation process in lib/silccrypt/rsa.c. The key length
4162 is now used to figure out the maximum size of the block allowed
4163 to be encrypted/signed.
4165 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4166 is equivalent to the silc_mp_mp2bin but does not allocate any
4169 * Changed silc_mp_mp2bin API to take length argument. If it is
4170 non-zero then the buffer is allocated that large. If zero, then
4171 the size is approximated using silc_mp_sizeinbase, which however
4174 * Created Global RNG API which is global RNG that application can
4175 initialize. After initializing, any routine anywhere in the
4176 code (including library) can use RNG without allocating a new
4177 RNG object. This was done to allow this sort of use of the
4178 RNG in code that has no chance to allocate RNG object. All
4179 applications currently allocate this and many routines in the
4180 library use this. Affected file lib/silccrypt/silcrng.[ch].
4182 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4183 it to use the Global RNG API.
4185 * Defined Authentication Payload into protocol specification that
4186 is used during SILC session to authenticate entities. It is
4187 used for example by client to authenticate itself to the server
4188 to obtain server operator privileges.
4190 Implemented this payload into the lib/silccore/silcauth.[ch].
4191 Implemented also routines for public key based authentication
4192 as the new protocol specification dictates.
4194 Moved definitions of different authentication methods from
4195 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4197 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4198 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4199 silc_pkcs_verify_with_hash functions into the file
4200 lib/silccrypt/silcpkcs.[ch].
4202 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * The client entry's userinfo pointer must be always valid.
4205 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4206 will fail since it requires the userinfo. Now, the userinfo
4207 is allocated as "" if actual userinfo does not exist. Actually,
4208 it must exist and it is totally Ok to drop client connections
4209 that does not announce the userinfo. However, we will make
4210 this workaround for now.
4212 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4213 to return the remote port by socket.
4215 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4218 SILC_SERVER_PENDING_EXEC and added an new macro
4219 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4220 data or when error occurs while processing the pending command.
4222 Added new argument `destructor' into silc_server_command_pending
4223 and to the SilcServerCommandPending object. This destructor is
4224 now called after calling the pending callback or if error occurs
4225 immediately. If error occurs the actual pending callback won't
4226 be called at all - only the destructor. The destructor may be
4227 NULL if destructor is not needed.
4229 All this applies for client library code as well. Similar
4230 changes were made there as well for the pending commands.
4232 In the client, the application must now allocate the
4233 SilcClientCommandContext with the silc_client_command_alloc
4236 * Added reference counter to the SilcServerCommandContext. Added
4237 function silc_server_command_alloc and silc_server_command_dup
4240 Same type of functions added to the client library for the same
4243 * Removed the cmd_ident from IDListData away since it is now
4244 global for all connections. It is the command identifier used
4245 in command sending and with pending commands. The affected file
4248 * Added reference counter to the SilcSocketConnection objecet to
4249 indicate the usage count of the object. The object won't be
4250 freed untill the reference counter hits zero. Currently only
4251 server uses this, and client ignores it. The client must be
4252 set to use this too later. The affected files are
4253 lib/silccore/silcsockconn.[ch]. Added also the function
4254 silc_socket_dup to increase the reference counter.
4256 This was mainly added because it is possible that the socket
4257 is removed underneath of pending command or other async
4258 operation. Now it won't be free'd and proper DISCONNECTING
4259 flags, etc. can be set to avoid sending data to connection that
4260 is not valid anymore.
4262 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4263 the connection. After that it sets SILC_SET_DISCONNECTED.
4264 It is, however, possible that the socket data is not still freed.
4265 The silc_server_packet_process now checks that data is not
4266 read or written to connection that is DISCONNECTED. The socket
4267 get's freed when the reference counter hits zero.
4269 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Changed the client operation API: channel_message operation's
4272 `sender' is now the client entry of the sender, not the nickname
4273 and the `channel' is the channel entry, not the channel name.
4275 In the private_message operation the `sender' is now also the
4276 client entry of the sender not the nickname.
4278 Affected file is lib/silcclient/ops.h and all applications
4279 using the client operations.
4281 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Moved the calling of ops->connect() from connect_to_server_final
4284 into receive_new_id functin since that is the point when the
4285 client is actually allowed to send traffic to network. The
4286 affected file is lib/silcclient/client.c.
4288 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4291 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4292 (if needs broadcasting) instead of broadcasting the packets one
4293 by one which would make a burst in the network traffic.
4295 * Added `broadcast' argument to the functions in silcd/server.[ch]
4296 silc_server_create_new_channel[_with_id] to indicate whether
4297 to send New Channel packet to primary router.
4299 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Added new function into the silcd/server.[ch] files:
4302 silc_server_create_new_channel_with_id to create new channel with
4303 already existing Channel ID.
4305 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4306 lib/silccore/silcpacket.h. This packet is used t send list of
4307 Set Mode payloads inside one packet. Server uses this to set
4308 the modes for the channels and clients on those channels, that it
4309 announced to the router when it connected to it. The protocol
4310 specification has been updated accordingly.
4312 * The silc_server_new_channel did not handle the packet coming
4313 from normal server as it normally does not send that. However,
4314 when it announces its channels it does send it. Implemented
4315 the support for that.
4317 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4318 into the file lib/silccore/id.h.
4320 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Fixed memory leaks in the functions silc_idlist_del_client,
4323 silc_idlist_del_channel and silc_idlist_del_server in the file
4324 silcd/idlist.c. All of those leaked like a sieve.
4326 * Fixed some small memory leaks in the client's function
4327 silc_client_notify_by_server.
4329 * Added functions into silcd/server.c: silc_server_announce_clients,
4330 silc_server_announce_channels and silc_server_announce_server.
4331 These functions are used by normal and router server to announce
4332 to its primary router about clients, channels and servers (when
4333 router) that we own. This is done after we've connected to the
4336 These functions effectively implements the following packet types:
4337 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4338 and SILC_PACKET_NEW_ID_LIST.
4340 * Added new functions into the silcd/packet_receive.[ch]:
4341 silc_server_new_id_list, silc_server_new_channel_list and
4342 silc_server_new_channel_user_list to handle the incoming
4343 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4345 * Added support of changing Channel ID in the function
4346 silc_server_replace_id. If the server that announces a channel
4347 to the router already exists in the router (with same name but
4348 with different Channel ID), router is responsible to send
4349 Replace ID packet to the server and force the server to change
4350 the Channel ID to the one router has.
4352 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4353 client that the Channel ID has been changed by the router. The
4354 normal server sends this to the client. Client must start using
4355 the new Channel ID as the channel's ID.
4357 Implemented handling of this new type into lib/silcclient/client.c
4358 into the function silc_client_notify_by_server.
4360 * Added new function silc_idlist_replace_channel_id into the files
4361 silcd/idlist.[ch] to replace the Channel ID.
4363 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4365 * Call silc_server_command_identify_check always when processing
4366 the IDENTIFY command in silcd/command.c
4368 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4371 send keepalive packets. The packet can be sent by clients,
4372 servers and routers.
4374 Added function silc_socket_set_heartbeat into the file
4375 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4376 If not set, the heartbeat is not performed. The actual
4377 heartbeat is implemented in the low level socket connection
4378 library. However, application is responsible of actually
4381 Added silc_server_send_heartbeat to send the actual heartbeat
4382 packet into silcd/packet_send.[ch]. Server now performs
4383 keepalive with all connections.
4385 * Added silc_task_get_first function into lib/silcutil/silctask.c
4386 to return the timeout task with shortest timeout. There was a bug
4387 in task unregistration that caused problems. TODO has been
4388 updated to include that task system must be rewritten.
4390 * The client library will now resolve the client information when
4391 receiving JOIN notify from server for client that we know but
4392 have incomplete information.
4394 * Rewrote parts of silc_server_remove_from_channels and
4395 silc_server_remove_from_one_channel as they did not remove the
4396 channel in some circumstances even though they should've.
4398 * Encryption problem encountered in server:
4400 The LEAVE command used to send the Channel Key packet to the
4401 router immediately after generating it. However, the code
4402 had earlier sent Remove Channel user packet but not immediately,
4403 ie. it was put to queue. The order of packets in the router
4404 was that Channel Key packet was first and Remove Channel User
4405 packet was second, even though they were encrypted in the
4406 reverse order. For this reason, MAC check failed. Now, this
4407 is fixed by not sending the Channel Key packet immediately but
4408 putting it to queue. However, this is more fundamental problem:
4409 packets that are in queue should actually not be encrypted
4410 because packets that are sent immediately gets encrypted
4411 actually with wrong IV (and thus MAC check fails). So, packets
4412 that are in queue should be encrypted when they are sent to
4413 the wire and not when they put to the queue.
4415 However, the problem is that the current system has not been
4416 designed to work that way. Instead, the packet is encrypted
4417 as soon as possible and left to the queue. The queue is then
4418 just purged into wire. There won't be any fixes for this
4419 any time soon. So, the current semantic for packet sending
4422 o If you send packet to remote host and do not force the send
4423 (the packet will be in queue) then all subsequent packets to the
4424 same remote host must also be put to the queue. Only after the
4425 queue has been purged is it safe again to force the packet
4428 o If you send all packets immediately then it safe to send
4429 any of subsequent packets through the queue, however, after
4430 the first packet is put to queue then any subsequent packets
4431 must also be put to the queue.
4433 Follow these rules and everything works fine.
4435 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Added new function silc_server_remove_clients_by_server to
4438 remove all client entries from ID list when the server connection
4439 is lost. In this case it is also important to invalidate all
4440 client entires as they hold the invalid server entry. This
4441 fixes fatal bug when server has lost connection and will reconnect
4444 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Made some sanity checks to silc_server_daemonise like to check
4447 whether the requested user and group actually exists.
4449 * Added sanity check to SKE's silc_ske_responder_finish to check
4450 that the public and private key actually is valid.
4452 * Invalidate the client's nickname when receiving Replace ID
4453 packet and the Client ID is being replaced. This means that the
4454 server will query the nickname if someone needs it (client)
4457 * Sort the ID Cache in client library when the ID Cache data
4458 has changed (needs sorting).
4460 * Do not allow for SILC client to create several connections to
4461 several servers. The client does not support windows right now
4462 and generating multiple connections causes weird behaviour.
4464 Irssi-silc client does support windows and can handle several
4465 connections without problems, see: www.irssi.org and SILC plugin.
4467 * Fixed some places where client was added to the IDList. The
4468 rule of thumb is following (in order to get everything right):
4469 If the client is directly connected local client then the
4470 `connection' argument must be set and `router' argument must be
4471 NULL to silc_idlist_add_client function. If the client is not
4472 directly connected client then the `router' argument must
4473 bet set and the `connection' argument must be NULL to the
4474 silc_idlist_add_client function.
4476 * The funtion silc_server_packet_send_local_channel actually did
4477 not check whether the client was locally connected or not. It
4478 does that now. Fixed a bug related to LEAVE command.
4480 * Fixed Remove Channel User payload parsing bug in server's
4481 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4483 * The server's silc_server_save_channel_key now checks also the
4484 global ID list for the channel as it might not be in the local
4485 list. Fixed a bug related to LEAVE command.
4487 * Is this the end of the [<unknown>] buglet that has been lurking
4488 around for a long time? A little for loop fix in server's
4489 silc_server_command_whois_parse that is used by both IDENTIFY
4490 and WHOIS command. At least, this was a clear bug and a cause
4491 of one type of [<unknown>] buglet.
4493 * WHOIS and IDENTIFY commands call the function
4494 silc_server_command_[whois/identify]_check function even if
4495 we are not router server.
4497 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Added --with-gmp configuration option. If set the GMP
4500 is always compiled in the SILC source tree. If not set then
4501 it is checked whether the system has the GMP3 installed. If
4502 it has then the GMP won't be compiled (the system's headers
4503 and library is used), if it doesn't have it then the GMP is
4504 compiled in the SILC source tree.
4506 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Changed RSA private exponent generation to what PKCS #1
4509 suggests. We try to find the smallest possible d by doing
4510 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4511 not security fix but optimization.
4513 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Added new config entry [Identity] to fork the server and run
4516 it as specific user and group. A patch from Bostik.
4518 * Imported Dotconf configuration library into lib/dotconf.
4519 This will be used to create the SILC configuration files later.
4520 It will appear in the distsribution after this commit.
4522 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * A big code auditing weekend happening. Auditing code for
4525 obvious mistakes, bugs and errors. Also, removing any code
4528 Removed files for being obsolete:
4530 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4531 inline in the file lib/silcutil/silcbuffer.h)
4533 o lib/silcutil/silcbufutil.c (the header has inline versions)
4535 Changed code to fix possible error conditions:
4537 o The buffer formatting routines now check that the destination
4538 buffer really has enough space to add the data. This applies for
4539 both buffer formatting and unformatting
4540 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4541 unformatting was changed to accomodate following rules:
4542 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4543 sent to the function while XXX_*STRING will not allocate or copy
4544 the data into the buffer. Instead it sets the pointer from the
4545 buffer into the pointer sent as argument (XXX_*STRING used to
4546 require that the pointer must be allocated already). This change
4547 makes this whole thing a bit more consistent and more optimized
4548 (note that the data returned in the unformatting with XXX_*STRING
4549 must not be freed now). The routines return now -1 on error.
4551 o Tried to find all code that use buffer_format and buffer_unformat
4552 and added return value checking to prevent formatting and
4553 especially unformatting errors and possible subsequent fatal
4556 o Changed ske->x and ske->KEY to mallocated pointers in
4557 lib/silcske/silcske.h. Fixed possible data and memory leak.
4559 o Added return value checking to all *_parse* functions. Fixed
4560 many memory leaks as well.
4562 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4563 so that buffer overflows would not happen. All code now also
4564 checks the return value as it can fail.
4566 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Added reconnection support to server if the normal server looses
4569 its connection to the router (for example if router is rebooted).
4570 The server performs normal reconnection strategy implemented
4571 to the server. Affected file silcd/server.c.
4573 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added new packet type SILC_PACKET_SET_MODE that is used to
4576 distribute the information about changed modes (for clients,
4577 channels and clients channel modes) to all routers in the
4578 network. Updated the protocol specification accordingly.
4580 Added functions into silcd/packet_send.c and
4581 silcd/packet_receive.c: silc_server_send_set_mode,
4582 silc_server_set_mode.
4584 Added new files silcmode.[ch] into lib/silccore that implements
4585 the encoding and decoding of Set Mode Payload. Added new type
4586 SilcSetModePayload. Moved the definitions of different modes
4587 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4589 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Oops, a little mistake in server's connection authentication
4592 protocol. The protocol is not ended with FAILURE but with
4593 SUCCESS if the authentication is Ok. :) Affected file is
4596 * Implemented NICK_CHANGE notify handling in server in the file
4597 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4598 the local clients on the channel. After the changing nickname
4599 in router environment snhould work and the [<unknown>] nickname
4600 should appear no more.
4602 The silc_server_replace_id function that receives the Replace ID
4603 payload now sends the NICK_CHANGE notify type also in the file
4604 silcd/packet_receive.c
4606 * Changed WHOIS and IDENTIFY command to support the maximum amount
4607 of arguments defined in protocol specs (3328 arguments). This
4608 fixed a bug that caused problems when there were more than three
4611 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Added extra parameter, command identifier, to the
4614 silc_client_send_command so that explicit command identifier
4617 Changed that ID list routines uses specific command identifier
4618 when sending WHOIS/IDENTIFY requests to the server so that they
4619 can be identified when the reply comes back.
4621 Affected files lib/silcclient/command.[ch],
4622 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4624 * Added `sender' argument to silc_server_packet_send_to_channel
4625 to indicaet the sender who originally sent the packet to us
4626 that we are now re-sending. Ignored if NULL. Affected file
4627 silcd/packet_send.[ch].
4629 * Added some server statistics support in silcd/server_internal.h
4630 SilcServerStatistics structure and around the server code. Also
4631 send some nice statistics information when client is connecting
4634 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4636 * Fixed channel ID decoding in server's JOIN command reply in
4637 silcd/command_reply.c
4639 * Fixed braodcasting of replace ID payload to not to send it if
4640 we are standalone server in silcd/packet_receive.c.
4642 * Fixed all channel message sending routines to not to send
4643 packets to clients that has router set, since they are routed
4644 separately in the same function earlier. Affects file
4645 silcd/packet_send.c and all channel packet sending functions.
4647 * In USERS reply, res_argv[i] are not allocated, the table
4648 is allocated. Thus changed that free the table, not its
4651 * In server's whois_check and identify_check if the client is
4652 locally connected do not send any WHOIS commands - they are not
4655 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Fixed some minor bugs in client when sending WHOIS command. The
4658 arguments was in wrong order.
4660 * Removed statis function add_to_channel from server in
4661 silcd/command.c that was previously used with the joining but
4664 * Tested USERS command in router environment successfully with two
4665 routers, two servers and two clients.
4667 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Reorganized the USERS command and command reply in client library
4670 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4671 When the command is given by user we register a pending command
4672 callback that will reprocess the command after the reply has been
4673 received from the server. When reprocessing the packet we then
4674 display the information. Thus, the USERS information is displayed
4675 now in the command callback instead of in the command reply
4676 callback. The processing of the command is same as previously
4677 when server has sent the command reply in the JOINing process.
4679 * Added to USERS command in silcd/command_reply.c to join the client,
4680 we didn't use to know about, to the channel after we've created
4681 a client entry for it. Also, for clienet we did know already still
4682 check whether it is on the channel or not and add it if not.
4684 * Removed silc_server_command_join_notify as the function and its
4687 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4689 * Changed the client's pending command handling to the same as the
4690 server's pending command handling. It is also now possible to
4691 execute command reply functions from other command reply
4692 function as the function callbacks for commands and command
4693 replies are one and same. The pending commands are not static
4694 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4695 in client connection context. Thus, pending commands are server
4696 connection specific as it is convenient.
4698 Changed the function silc_client_command_pending and
4699 silc_client_command_pending_del and added new function
4700 silc_client_command_pending_check. Removed the
4701 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4704 * Added cmd_ident, current command identifier, to the client
4705 connection context in lib/silcclient/client.h to keep track on
4706 command identifiers used in command sending. Client's command reply
4707 function handling now supports the mandatory command identifiers.
4709 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4710 funtions in client to fully support pending command callbacks.
4712 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4713 as one of the arguments to the application in the command reply
4716 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4717 before first releasing SILC but came back. Now it is removed again
4718 and should come back nomore. The FORWARDED flag was used only
4719 by the JOINing procedure by forwarding the command packet to router.
4720 Now, the JOINing procedure has been changed to more generic (due
4721 to various router environment issues) and FORWARDED is not needed
4722 anymore for anything. The protocol specification is yet to be
4725 Now, removed silc_server_packet_forward from server and the flag
4726 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4728 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Renamed NAMES command to USERS command. The NAMES was named that
4731 due to historical reasons. Now it is renamed. Also, rewrote
4732 parts of the USERS command. The nickname list is not sent anymore
4733 by the server. Only Client ID and mode lists are sent in the USERS
4734 command. Changed this also to the protocol specification.
4736 The client now resolves the names and stuff after it receives
4737 the USERS list from the server when joining to the channel.
4739 * WHOIS and IDENTIFY commands has been changed to support multiple
4740 Client ID's per command. One can now search for multiple users
4741 in the network by sending only one WHOIS or IDENTIFY command.
4742 Changed the code and the protocol specifications.
4744 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4745 uses silc_server_command_whois_parse to parse the request. */
4747 * If normal server, do not parse the WHOIS and IDENTIFY requests
4748 before sending it to the router. Saves some time.
4750 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Fixed JOIN command on client library. Wrong number of arguments
4753 used to crash the client.
4755 * Added silc_server_channel_has_global function to check whether
4756 channel has global users or not.
4758 * Added silc_server_channel_has_local function to check whether channel
4759 has locally connected clients on the channel.
4761 * The silc_server_remove_from_one_channel now checks whether the
4762 channel has global users or not after given client was removed from
4763 the channel. It also checks whether the channel has local clients
4764 on the channel anymore. If it does not have then the channel entry
4765 is removed as it is not needed anymore.
4767 * The silc_server_notify now checks on JOIN notify whether the joining
4768 client is one of locally connected or global. If it is global then
4769 the channel has now global users on the channel and that is marked
4770 to the channel entry. Also, it now saves the global client to
4771 global list who is joining and JOINs it to the channel. This is
4772 for normal server, that is.
4774 Changed silc_server_send_notify_on_channel,
4775 silc_server_packet_relay_to_channel and
4776 silc_server_packet_send_to_channel check if we are normal server
4777 and client has router set (ie. global client) do not send the
4778 message to that client, as it is already routed to our router.
4780 * Implemented LEAVE notify type handling in silc_server_notify
4783 * Tested LEAVE command in router environment successfully. Tested
4784 with two routers, two servers and two clients.
4788 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4790 * Implemented SIGNOFF notify type handling in silc_server_notify
4793 * silc_server_remove_id now removes the client entry from all channels
4794 it has joined and thusly sends SIGNOFF notify type.
4796 * Rewrote the NAMES list generation in server by removing two excess
4797 loops. The lists are created now inside one loop.
4799 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4801 * silc_server_remove_channel_user checks now also global list
4802 for channel and client.
4804 * silc_server_new_channel_user checks now both local and global
4805 list for channel and client. Fixed a bug in client id decoding.
4806 Used to decode wrong buffer.
4808 * silc_server_channel_message checks now both local and global
4809 list for channel entry.
4811 * Tested channel joining (hence JOIN) in router environment
4812 successfully. Tested with two routers, two servers and two
4815 * Tested channel message sending in router environment successfully.
4817 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Added silc_server_save_channel_key into server.[ch] to save the
4820 received channel key in Channel Key payload processing. It is
4821 also used in JOIN command reply handling.
4823 Equivalent function silc_client_save_channel_key added into
4824 client.[ch] into client library.
4826 * Changed JOIN command reply to send information whether the channel
4827 was created or not (is existing already) and the channel key
4828 payload. Changed protocol specs accordingly.
4830 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4831 the request was sent by ID and not by nickname. Crashed on
4834 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4837 now correctly save the received data.
4839 * silc_server_free_sock_user_data now notifies routers in the
4840 network about entities leaving the network.
4842 At the same time implemented functions silc_server_remove_id
4843 and silc_server_send_remove_id to receive and send REMOVE_ID
4844 packets. The packet is used to notify routers in the network
4845 about leaving entities. The ID removed will become invalid in
4848 * Added function silc_idlist_del_server into server. Removes and
4849 free's server entry from ID list.
4851 * silc_server_private_message function now checks, if we are router,
4852 that the destination ID really is valid ID, naturally.
4854 * In router when NEW_ID packet is received (for new client) the
4855 hash of the Client ID is saved in the ID Cache but the
4856 client->nickname is set to NULL, instead of putting the hash
4859 IDENTIFY command now also checks that client->nickname must be
4860 valid. If it is not if will request the data from the server who
4861 owns the client. Added new function
4862 silc_server_command_identify_check.
4864 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4865 to set the command to already allocated Command Payload.
4867 * Tested private message sending in router environment with two
4868 routers, two servers and two clients. Fixed minor bugs and now
4871 * Fixed segfault from client's NAMES command. Used to crash if
4874 * Forwarded packets must not be routed even if it is not destined
4875 to the receiver. Changed server code comply with this.
4877 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Added `require_reverse_mapping' boolean value to ServerParams
4880 structure. If TRUE (not default) the server will require that
4881 the connecting host has fully qualified domain name.
4883 If the reverse mapping is not required and hostname could not be
4884 found the IP address is used as hostname.
4886 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Implemented version string checking to both client and server.
4889 The check is incomplete currently due to the abnormal version
4890 strings used in development version of SILC.
4892 * Changed all command functions in server to use the new
4895 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Changed char *data to unsigned char *data in ID Cache system to
4898 support binary data as ID Cache data. Changed code to support
4899 binary data in lib/silccore/idcache.c.
4901 * Renamed silc_server_packet_relay_command_reply to
4902 silc_server_command_reply as it is normal packet receiving
4903 function. Rewrote the function to accept command replys for
4904 servers and not only for clients.
4906 * Mark remote router always as registered server if we are connecting
4907 to it. Otherwise, commands sent by the router to us are ignored.
4909 * All ID List find routines now returns the ID Cache Entry pointer
4910 as well if requested.
4912 * WHOIS command works now in router environment, tested with two
4913 routers, two servers and two clients.
4915 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4916 in router environment (as it is almost equivalent to WHOIS) but
4917 hasn't been tested thoroughly. Added new functions:
4919 silc_server_command_identify_parse
4920 silc_server_command_identify_send_reply
4921 silc_server_command_identify_from_client
4922 silc_server_command_identify_from_server
4924 * Disabled route cache adding because adding two different ID's with
4925 same IP replaces the old cache entry thus giving wrong route.
4926 The entry->router->connection is always the fastest route anyway
4927 so route cache may not be needed. Of course, new routes maybe
4928 established after receiving the ID when the entry->router->connection
4929 might not be anymore the most optimal.
4931 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Add route cache for received ID for fast routing.
4935 * Added silc_server_packet_route to route received packet on router
4936 that is not destined to us.
4938 * Renamed silc_server_get_route to silc_server_route_get.
4940 * Added id_string and id_string_len fields into SilcServer to
4941 include encoded ServerID for fast comparing without excess
4942 encoding of the ID's.
4944 * Cleaned up WHOIS command on server side. Added following static
4947 silc_server_command_whois_parse
4948 silc_server_command_whois_check
4949 silc_server_command_whois_send_reply
4950 silc_server_command_whois_from_client
4951 silc_server_command_whois_from_server
4953 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4954 arguments in command replies. All command functions should be
4955 updated to use this macro.
4957 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Minor typo fixes on command reply handling on server.
4961 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Added silc_server_command_add_to_channel internal routine to add
4964 the client to the channel after router has created the channel and
4965 sent command reply to the server.
4967 * Added generic silc_server_send_command to send any command from
4970 * Use static buffer with ID rendering instead of duplicating data.
4972 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Fixed a channel user mode bug when joining to a channel server gave
4975 everybody channel founder rights, oops.
4977 * We mark ourselves as the router of the incoming server connection
4978 if we are router ourselves. This way we can check in some packet
4979 sending functions whether it is locally connected server. For
4980 incoming router connections we put NULL.
4982 * For router sending packets locally means now always sending the
4983 packet cell wide; to local clients and local servers. For normal
4984 server sending packet locally means sending it to only local
4987 * Fixed the JOIN command to really work in router environment. If the
4988 channel is created it is always created by the router. Router is
4989 also responsible of making the initial joining to the channel,
4990 sending JOIN notify to the sending server and distributing
4991 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4992 does not exist server doesn't do anything else but forward the
4993 command to the router which performs everything.
4995 * Added silc_server_send_channel_key function to send the Channel Key
4998 * Added silc_server_create_channel_key to create new channel key. The
4999 channel key is now re-generated everytime someone joins or leaves
5000 a channel, as protocol dictates. Note: channel->key_len is the
5003 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5006 packet_receive.[ch] to separate packet sending and receiving
5007 routines. The server.[ch] now includes everything else including
5008 actual packet processing (writing and reading data) and other
5011 Renamed silc_server_private_message_send_internal to
5012 silc_server_send_private_message. The routine is still though
5013 used only to relay private messages as server does not send
5014 private messages itself.
5016 Renamed silc_server_new_channel to silc_server_create_new_channel
5017 and added new function sicl_server_new_channel that handles the
5018 incoming New Channel packet. Added also new sending function
5019 silc_server_send_new_channel to send New Channel Payload.
5021 * Added new function silc_server_notify to process incoming notify
5022 packet to the server/router. Server may then relay the notify
5023 to clients if needed.
5025 * Added new function silc_server_new_channel_user to process incoming
5026 New Channel User packet. Router will redistribute the packet and
5027 send JOIN notify to its local clients and locally connected servers
5028 if needed. Normal server will send JOIN notify to its local client
5029 on same channel when received this packet. Added also corresponding
5030 sending function silc_server_send_new_channel_user to sent the
5033 * Added boolean route argument to send_notif_to_channel and
5034 packet_send_to_channel functions to attempt to route the packet
5035 if it is TRUE and send only locally if it is FALSE.
5037 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * silc_server_replace_id now broadcasts the received replace ID
5040 packet if it is not broadcast packet already. The router must
5041 broadcast to inform other routers about changed ID.
5043 * Added backpointer to server's router into SilcServer context in
5044 silcd/server_internal.h.
5046 * Fixed silc_server_packet_broadcast to send correct broadcast
5049 * The channel key is now distributed to the local client as soon
5050 as it is received from the router (in router environment) so that
5051 no other packet may be sent for the channel until client has
5054 * silc_server_remove_channel_user now broadcasts the received
5055 Remove Channel User packet if it is not broadcast packet already.
5056 The router must broadcast to inform other routers about removed
5059 * Added users field into SilcPacketContext that is a reference count
5060 of the context. One can increase the reference count by calling
5061 silc_packet_context_dup which is now changed to just increase the
5062 reference count instead of duplicating the data. The reference
5063 count is decresed by calling silc_packet_context_free that will
5064 free the data after the reference count hits zero.
5066 For now on the packet context and everything allocated into it
5067 (including the raw packet from network) must be freed by calling
5068 the new silc_packet_context_free function. Added also new function
5069 silc_packet_context_alloc that must be used now to allocate the
5070 context. This also means that if a routine is asynchronous from
5071 silc_[client/server]_packet_parse_type the packet context must
5072 be duplicated by calling silc_packet_context_dup. Otherwise it
5073 gets free'd after silc_[client/server]_packet_parse_type returns.
5074 Also, one must remember that if packet is duplicated then its
5075 reference count must be decresed by calling the free function as
5076 many times as it was duplicated.
5078 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5079 from both client and server.
5081 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Made joining to a channel working in router environment.
5085 * Cleaned up JOIN command on server side and create function
5086 silc_server_command_join_channel internal routine to make the
5089 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Changed silc_command_pending list to SilcDList. Also, added
5092 `ident' field to SilcServerCommandPending structure to identify
5093 the reply and to call correct callback.
5095 Added silc_server_command_pending_check function to replace the
5096 corresnponding macro. The silc_command_pending list is not
5099 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5100 to set identifier to previously allocated Command Payload. It
5101 is used to set identifier for command when resending Command
5104 * Added silc_command_payload_encode_payload to encode Command
5105 Payload buffer from SilcCommandPayload structure.
5107 * Added silc_argument_payload_encode_payload to encode Argument
5108 payload buffer from SilcArgumentPayload structure.
5110 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Changed WHOIS command to support router connection on server side.
5113 The whois request is always sent to router unless the server is
5114 standalone server. After server has received the reply from the
5115 router will it send the reply to the client.
5117 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5118 broadcast received broadcast packet. The function is used only
5119 by router. The broadcast packet is always sent to the router's
5122 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5123 render given ID to printable string, for log files for example.
5125 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Made basic router to router connections working. At least they
5128 can now connect to each other but nothing really works the way
5129 they are supposed - yet.
5131 * Added new initiator token to RouterConnection configuration
5132 file in silcd/serverconfig.[ch]. It is used to tell whether we
5133 are the initiator to the remote router or whether we'll expect
5134 the other end to connect.
5136 * Moved registering of listener task to silc_server_init, hence
5137 the server starts listenning as soon as it is run, even if it
5138 does not have connections to other routers. Let's see how well
5141 * Changed default connection retry timeouts for more suitable in
5144 * Removed cipher and such arguments from silc_idlist_add_client
5145 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5146 Added new function silc_idlist_add_data to add the keys and stuff
5149 * Added SilcIDListData structure and added it to SilcClientEntry
5150 and SilcServerEntry as their first field in the structure. This
5151 way we can explicitly cast the ID entries to the SilcIDListData
5152 structure and get common data for the entries. In past, we had
5153 to first check what type of connection it is and then cast it to
5154 correct ID entry type. Now, we can directly cast the opaque
5155 pointer to the SilcIDListData (no matter what ID entry it actually
5156 is) and get the data needed.
5158 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5161 in some circumstances even if threre were timeout tasks, though not
5162 IO tasks, but tasks anyway. Now fixed.
5164 * Defined SilcServerConnection structure to hold connection specific
5165 stuff about directly connected servers and routers. The definition
5166 is currently in silcd/server_internal.h. I thought about having
5167 a bit more important role fro this struct but for now it is used
5168 only when connecting to other server (or router actually).
5170 * Added connecting retry support in server when connecting to
5171 router(s). The retry feature implement exponential backoff
5172 algorithm. Also, added SilcServerParams structure to hold default
5173 parameters for server. For now, it include these retry settings
5174 and are hard coded. After server is moded to be as Silc Server
5175 Library this structure will be more important.
5177 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5179 * Changed client librarys channel->clients table to SilcList and
5180 changed code accordingly.
5182 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Changed client's channel table to SilcList and changed code
5185 accordingly. Also changed SilcChannelClientEntry to include back-
5186 pointer to the channel so that client entry can use that structure
5187 as list as well and we have fast cross-reference to the channel.
5188 This change dramatically decreased the complexity of channel
5189 handling with client entry and vice versa (removed one extra
5190 loop when searching for channel entry from many functions).
5192 * Changed server->sim from table to SilcDList and changed code
5195 * NAMES command can now be used from user interface. It will show
5196 the user list on the channel, neatly.
5198 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5199 Code now saves realname of the user if it becomes available.
5201 * Renamed configure.in to configure.in.pre and made ./prepare
5202 script to automatically add correct version string to
5203 configure.in which it creates from configure.in.pre.
5205 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * NAMES command reply now shows users mode with the nickname when
5210 * Moved silc_client_ch[u]mode[_char] functions from
5211 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5212 place sucks, they are utility functions and should be in some
5215 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5217 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5220 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Added TRQ (efficient deque and list library) into lib/trq. This is
5225 a very good list library that is currently used in the SILC. Defined
5226 SilcList API over the library because I didn't like the API very
5227 much. See lib/trq/silclist.h for the API and examples of how to
5228 use the API. Fixed various places in the code to use the new
5229 SilcList API. The SilcList is meant for lists that has a structure
5230 already defined as a list. It is not suitable to add just some
5231 context to the list (in TRQ, the context is the list actually).
5233 So, I defined SilcDList that can be used for the purpose where
5234 predefined list structure does not exit. This can be used as
5235 such list. Now some context just can be added to the SilcDList.
5236 Currently this list is not used in the SILC just yet, though there
5237 are a lot places where this can replace dynamically allocated
5238 tables and I will fix these places, later, to use SilcDList.
5239 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5240 and use TRQ internally).
5242 Also fixed some annoying warning messages that the original TRQ
5243 code generated. Also minor changes to TRQ's Makefile.in.
5245 * Added support for querying by Client ID to both WHOIS and
5246 IDENTIFY commands into server, as required by the protocol.
5248 * Removed method function pointers from SilcBuffer structure. They
5249 weren't used to anything and just increased the context size for
5250 no good reason. This change also made silc_buffer_alloc and
5251 silc_buffer_free functions inline functions.
5253 * Disabled command flooding detection support until it's fixed so
5254 that it accepts commands in but does not execute them more than once
5257 * Added silc_net_localhost(), to return local hostname, into
5258 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5259 that must be initialized before calling silc_client_init.
5261 * Added new function: silc_server_send_notify_on_channels to send
5262 notify messages to all channels client has joined. It is assured
5263 that the message is sent only once per client.
5265 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5266 lib/silcutil/silcutil.[ch] as silc_format function. The new
5267 function is generic and is used by server as well, not only by
5268 the logging routines.
5270 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5271 the provided version string was not acceptable. Added new function:
5272 silc_ske_check_version into lib/silcske/silcske.h. The function
5273 must be implemented by the application (client or server) and it
5274 does not reside in the SKE library. The function checks the version
5275 string remote end sent.
5277 * Added back pointers (to opaque context and to SilcSocketConnection)
5278 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5280 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5281 duplicate packet context structure.
5283 * Changed `notify' client operation to send same arguments as client
5284 receives from server except for ID's. ID's are mapped to correct
5285 ID entry and that is returned. Also, if channel entry is not sent
5286 by server but the notify is for channel the channel entry is sent
5287 to application (otherwise application doesn't know that it is for
5288 channel (library gets it from packet's Destination ID)).
5290 * Added silc_client_remove_from_channels into client library to
5291 remove a client from all channels it has joined to. Used when
5292 received SIGNOFF notify from server. Added also new function
5293 silc_client_replace_from_channels to replace old ID entry with
5294 new ID entry on all channels. Used when received NICK_CHANGE
5297 * Fixed ID Cache list handling in silc_idlist_get_client in
5298 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5299 to get (or query) client by ID.
5301 * Updated TODO list.
5303 * Added connection authentication status message defined by the
5304 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5305 support for these into the code in client and server side.
5307 * Added generic function silc_client_send_command to send any command
5308 with variable argument list. Application should use this function
5309 to send commands if the command functions provided by the library
5310 does not suite for the application's user interface needs.
5312 * Added new `failure' client operation. Application is notified about
5313 received failure packet if client is executing a protocol. In this
5314 case the protocol's execution has failed.
5316 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5317 is required by the protocol.
5319 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5320 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5323 * Added status flag to SilcSKE object to indicate realtime status
5324 of the SKE protocol.
5326 * Application receives now exactly same command reply arguments as
5327 the library receives from server. However, if ID is received the
5328 corresponding ID entry is returned to the application (eg. Client
5329 ID is mapped to correct SilcClientEntry entry and that is returned).
5330 Changed command_reply client operation due to this change.
5332 * Changed all ID's in commands and in command replys as ID Payloads.
5333 Change affected both client and server side codes.
5335 All ID's sent in SILC network (with execption of ID's in SILC
5336 Packet header) are sent in ID Payload to support variable length
5339 * Server now notifies nick changes and notifies all clients on
5340 the channels about the new nickname (about the new Client ID,
5343 * Implemented CMODE command to change channel modes. Supports all
5344 channel modes defined by the protocol specs except ban and invite
5345 lists. (Also, private channel key mode is supported but support for
5346 setting private channel key in client is missing, thus, this mode
5347 has no effect on client side (except that server requires that the
5348 client uses private channel key and normal channel traffic does not
5351 Also, invite mode works per se, but INVITE command does not work
5352 yet correctly, so you can set channel as invite only channel but
5353 inviting clients to the channel does not work (it is yet to be
5354 thought what's the best way to do it).
5356 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5357 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5358 Implemented CUMODE command to change user's mode on the channel.
5359 Supports all modes defined by the protocol specs.
5361 * Added NAMES command reply to return users modes on the channel.
5363 * Removed unnecessary and slow ciphers from lib/silccrypt.
5365 * Set SO_KEEPALIVE option to connection sockets by default.
5367 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5369 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5370 redefined the Notify Payload into protocol specs.
5372 * Added silc_id_payload_parse_id to get ID directly from raw
5375 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5378 accept searching by Client ID as well.
5380 * Added support for LEAVE and SIGNOFF notify types in client library.
5382 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5383 to parse ID Payload from raw data.
5385 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Added flags parameter into silc_ske_assemble_security_properties
5388 function in lib/silcske/silcske.[ch].
5390 * Changed notify client operation to fit better for notify messages
5391 sent by server. The notify payload received from server is now
5392 passed to the application (after parsing it to SilcNotifyPayload).
5393 It is application's responsibility to retrieve the arguments
5394 from the payload and show the message the way it wants. The message
5395 sent by server is implementation specific.
5397 * Changed public keys to comply with the protocol specification.
5398 Old public keys are not supported anymore and are not compatible.
5400 * Removed nickname from Channel Payload as the latest draft removed
5401 it. The client must resolve the nickname from the NAMES command
5402 reply received when it joined the channel.
5404 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5406 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Fixed some errors in protocol specification drafts.
5410 * Created lib/silccore/silcnotify.c to implement Notify Payload
5411 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5412 generic payloads described by protocol specifications. The file
5413 includes implementations for ID Payload and Argument Payload.
5415 * Changed Command Payload implementation to use the new Argument
5416 Payload. Changed command_xxxx_payload to command_payload_xxxx
5417 to comply with SILC coding conventions.
5419 * Added suppport for Argument Payload handling in Notify Payload
5420 implementation as protocol requires it. Added the new support
5421 into server and client lib as well.
5423 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Added support for multiple nicknames on same channel. [n] is
5426 added locally to the nickname if there are more than one same
5427 nicknames on the channel.
5429 * Server now sends all nicknames that matched WHOIS request.
5430 Client also shows the list received from server.
5432 * Added TOPIC command to client side. User can now set and show
5433 current topic on channel.
5435 * Added MOTD command to client and server. Also, server sends the
5436 motd when client connects to the server.
5438 * Changed version strings to comply ISO 8601.
5440 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Fixed protocol error handling in client library. It should now
5443 cope even if the SKE fails for some reason.
5445 * Made new protocol specification drafts for submitting to IETF.
5447 * Implemented TOPIC command to server in silcd/command.c.
5449 * Added two new notify types into lib/silccore/silcnotify.h:
5450 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5451 notify nickname change and topic setting/change on a channel.
5453 * API change of command_reply operation in client library. The
5454 application gets now the status type received from server as well.
5456 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5460 * Cras fixed and optimized the packet handling even further and
5461 it should work now. Minor change to the prototype of function
5462 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5464 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Added new function into lib/silcutil/silcschedule.[ch]:
5467 silc_schedule_with_fd to select() a specified fd. The function
5468 returns after timeout expires or data arrives or goes. The
5469 function is used by packet routines to wait that all data is
5470 received from network.
5472 * Fixed data reading from network in lib/silccore/silcpacket.c.
5473 The code now assures that all data is read from the fd and then
5474 continues packet processing. This was a bug fix since the code
5475 used to drop some data in some circumstances.
5477 * Added new function into lib/silcclient/client.[ch]:
5478 silc_client_start_key_exchange to start key exchange after
5479 connection has been established to server. The code internally
5480 now uses this funtion but its main purpose was to provide it
5481 for applications that perform their own connecting. After
5482 application has created a connection it merely calls this
5483 function to start the key exchange between client and server.
5484 The library takes care of everything else after that.
5486 Updated also lib/silcclient/README to explain the usage of
5489 * Do not send to application information that connection has
5490 been established. Application gets notified it by connect
5493 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Applied cras's patch to add silc_schedule_one function. The
5496 function runs scheduler once and returns.
5498 * Fixed the scheduler after cras messed it up. The timeout
5499 handling works now as it's supposed to work.
5501 * Added into lib/silccore/ silcnotify.h to include notify
5502 message types support. Changed silc_server_send_notify*
5503 functions, in server.[ch], to support those new notify types.
5504 Added the support for the notify types into client library,
5505 as well. Added new notify client operation into ops.h in
5508 * Changed silc_server_packet_send_to_channel to send normal
5509 packets instead of just channel message packets. The function
5510 is now used to send the notify packets to channels. It is not
5511 used to send channel message packets anymore, as server never
5514 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5515 va_arg()s as it seems to require it nowadays. I guess, if SILC
5516 is compiled with older va_arg() the new code should work anyway.
5518 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Splitted core library. Core library (lib/silccore) includes
5521 now only SILC protocol specific core (and common) components.
5522 Created new utility library (lib/silcutil) that includes more
5523 generic purpose stuff. The stuff for util library was taken
5524 from the old core library. This was minor and easy split.
5526 * Created SILC Client Library (lib/silcclient) that includes
5527 implementation of the SILC client without user interface. This
5528 was major move from silc/ directory. The code has been changed
5529 so that it is transparent towards the user interface. The
5530 silc/ directory includes now the same user interface as before
5531 and it uses the new client library. Read lib/silcclient/README.
5532 Basicly, the client library performs everything else related
5533 to SILC except user interface handling. Also, configuration
5534 files are considered to be part of user interface and library
5535 does not handle them.
5537 This change also changed a lot of structures, function naming etc.
5538 Most important change was that SilcClientWindow object was
5539 renamed to SilcClientConnection in the client library. Created
5540 also new file lib/silcclient/ops.h. Also added new files
5541 silc/local_command.[ch] and silc/client_ops.[ch].
5543 All these changes were made to make it easier for user interface
5544 designers to create what ever user interface for the SILC client
5547 It is also expected that the server will be moved to lib
5548 directory as well and SILC Server Library will be created;
5549 sometimes in the future.
5551 * Removed Local commands from lib/silccore/silccommand.h as
5552 they are application specific and new client library does not
5553 handle any of those anymore.
5555 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5556 old client implementation in silc/.
5558 * Added support for callback functions in SILC_LOG_* macros.
5559 Application can now set its own callbacks that will be called
5560 instead of using the default functions that will always print
5561 the debug messages to stderr (or stdout). Also, debugging can
5562 now be disabled by setting silc_debug to FALSE and re-enabled by
5563 setting it to TRUE. Note, that logging will still work even
5564 if debugging is disabled.
5566 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5567 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5568 silc_log_reset_debug_callbacks.
5570 * To enable debugging in silc client one must give now -d
5571 option on command line.
5573 * Changed silc_schedule_init to automatically allocate task queues
5574 if they are not allocated before calling it.
5576 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Added GMP 3.1 into math library.
5580 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5583 a channel in SILC network. The packet is used by servers and
5584 routers to notify other routers that user has left a channel.
5585 This little feature was missing until now. Added the feature
5586 to protocol specification as well.
5588 Added functions: silc_server_send_remove_channel_user and
5589 silc_server_remove_channel_user into server.[ch].
5591 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5592 lib/silccore/silcpacket.h. However, they are not implemented
5595 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Fixed joining to a channel and sending channel messages
5598 between server and router. The channel message sending should
5599 now work inside a cell.
5601 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Fixed the private message sending between server and router.
5604 The private message sending should now work inside a cell.
5606 * Added silc_server_replace_id into server.[ch] to replace
5607 existing ID in the SILC network.
5609 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5610 and silc_idlist_replace_server_id into idlist.[ch] in server.
5612 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Fixed the server to server connections. Server can again now
5615 connect to router. Router to router connections probably does
5618 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added dynamic protocol registering support. Now protocols can
5621 registered and unregistered on the fly. Patch by cras.
5623 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Added lib/contrib directory to hold routines that some platforms
5626 don't have but are needed by SILC.
5628 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5629 into lin/contrib to provide getopt() and getopt_long() for
5630 those who don't have it.
5632 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Added AWAY command to client. When away message is set and
5635 client receives a private message packet the client automatically
5636 replies to the sender with the away message.
5638 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5639 bug seemed to be the cause of recent problems when compiling
5642 * Added version detection support to SKE protocol specification
5643 and added the new changes to the SKE implementation as well.
5644 There were other minor changes in the SKE protocol as well.
5646 Many changes in lib/silcske/silcske.[ch] and in
5647 lib/silcske/payload.[ch].
5649 * Added ^U functionality, clear input line. Patch from cras.
5651 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Mainly small bugfixes on core library. Fixed some debugging
5654 logging and buffer overflow in silclog.c.
5656 * Updated config.sub and config.guess on the distribution tree.
5658 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Added command lagging support in server. Client may execute
5661 commands now only once in two seconds.
5663 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Optimized packet reception. MAC computation and checking is now
5666 also more optimized. A lot previously duplicated code is now
5667 used as generic by both client and server.
5669 * Fixed key pair generation in clientutil.c
5671 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Added into lib/silccore/silcbufutil.[ch] new function;
5674 silc_buffer_realloc.
5676 * Moved generic packet sending/encryption functions to
5677 lib/silccore/silcpacket.[ch] from client and server. Some
5678 rewriting of the functions.
5680 * Moved all generic packet reception/decryption functions to
5681 lib/silccore/silcpacket.[ch] from client and server. The
5682 packet processing is now much cleaner in both client and server.
5683 These were major changes in both client and server.
5685 * Created many common functions in server to do packet sending.
5686 Previously code were duplicated a lot, this has been removed
5689 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Rewrote major parts of the ID cache system. Don't know
5692 whether it is better now or not but at least the API is more
5695 * Major rewrite on ID cache stuff on client because of the ID
5696 cache API changes. Added idlist.c to client.
5698 * Also major rewrite on ID cache stuff on server as well.
5699 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5700 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5701 in hand, instead they are all put into the ID cache system now.
5702 All server_idlist_* routines uses ID cache now instead of
5703 traversing its own lists (those lists does not exist anymore).
5704 SilcIDList though still exists. Also, SilcXXXEntry's are
5707 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Finally made the SKE implementation compliant to the protocol
5710 specification. All mp integers are now binary encoded as
5711 opposed being HEX encoded.
5713 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5716 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5717 functions: silc_[encode/decode]_pem. Also added function
5718 silc_encode_pem_file to PEM encode with newlines ('\n') for
5721 * SILC public keys are now encoded either PEM or binary. Same
5722 option is for private keys as well. By default private keys
5723 are binary encoded and public keys PEM encoded. Silly HEX
5724 encoding were removed.
5726 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5727 function to create fingerprints.
5729 * Fixed a bug in SHA1; does not change the original data anymore.
5731 * Partly implemented INFO command on client and server side.
5732 Fixed CLEAR command. Changes to SERVER command; show current
5733 server(s) when giving command without arguments. Added
5734 VERSION command to client.
5736 * Added check to server that unregistered connections cannot
5737 execute commands (unless it is specificly allowed).
5739 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Fixed screen refresh.
5743 * Fixed channel joining bug from client. On some circumstances
5744 client tried to join to a channel it had already joined.
5746 * Added public key verification process into client's protocol.c.
5747 The client now verifies the public key from user and saves
5748 it into ~./silc/serverkeys/ directory.
5750 Added into: clientutil.[ch]: silc_client_verify_server_key.
5752 * Changed SKE protocol's silc_ske_initiator_finish function
5753 to accept callback function that verifies the received public
5754 key. Removed old silc_ske_verify_public_key function.
5756 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5759 silc_pkcs_private_key[_data]_set.
5761 * Made the password and public authentication more cleaner in
5762 server's protocol.c.
5764 * Removed historic and obsolete protocol `channel_auth' from
5765 both client and server.
5767 * Removed wrong way of sending command status messages from
5768 server to client in server's command.c. The old way violated
5769 protocol specification.
5771 Changes to silccore/silccommand.[ch]: removed
5772 silc_command_encode_status_payload -> not needed anymore,
5773 changed silc_command_encode_payload_va to accept extra
5774 argument on variable argument list. The argument type must
5775 now be provided to the function. Also, added new function:
5776 silc_command_encode_reply_payload_va which is same as
5777 normal command_encode_payload_va except command status type
5778 is provided as extra argument.
5780 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Added ~./silc directory handling. The directory includes the
5783 public and private keys for the client.
5785 Added silc_client_check_silc_dir, silc_client_create_identifier
5786 and silc_client_load_keys.
5788 * Implemented SILC protocol compliant public key. Added public
5789 and private key saving to and loading from files.
5791 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5792 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5793 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5794 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5795 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5797 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5798 silc_pkcs_load_[public/private]_key.
5800 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Added silc_server_get_route (route.[ch]) to get connection
5803 data for the fastest route for given ID.
5805 * Implemented INVITE command on client and server. The command
5806 were re-defined in the SILC Protocol Specification and the
5807 implementation now complies with the specification.
5809 * Implemented PING command on client and server.
5811 * Implemented NAMES command on client and server. The server side
5812 supports currently only normal server not router server yet.
5813 Some changes to NAMES definition in SILC protocol specification.
5815 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Implemented LEAVE command on client and server.
5819 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5820 again. This change was made to the protocol as well. Server
5821 should not violate the protocol specification anymore.
5823 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5826 was tested. SOCKS4 was not but should work anyway.
