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

100 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
102 * Assure that silc_client_notify_by_server_resolve does not
103 resolve the client information multiple times. If it cannot
104 be found by the first it cannot be found at all. Affected
105 file lib/silcclient/client_notify.c.
107 * Fixed WHOWAS command reply calling. Affected file
108 lib/silcclient/command_reply.c.
110 * Removed all references to silc_idlist_get_client from the
111 Irssi SILC client since that call is internal call used by
112 the library. The Irssi SILC client will use now client
113 retrieval functions found in silcapi.h.
115 * Fixed a bug in resolving nickname info before sending
116 private message. It used freed memory. Affected file
117 irssi/src/silc/core/silc-servers.c.
119 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

143 in packet queue that we are not able to process without first
144 processing packets before them. Affected file silcd/server,
145 lib/silcclient/client.c.
147 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
148 whether library should continue processing the packet.

232 * Redefined the SILC packet header to include the padding
233 length. Affected file lib/silccore/silcpacket.[ch].
235 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
236 length for maximum padding up to 128 bytes). Affected
237 file lib/silccore/silcpacket.h.
239 * Removed all backwards support for old 0.5.x MAC thingies.
240 The SILC packet header change makes it impossible to be
241 backwards compatible.
243 * Send the ENDING packet with timeout in the backup resuming
244 protocol. This is to assure that all routers has connected
245 to the primary router. Affected file silcd/server_backup.c.
247 * Changed the RNG to take the first IV from random data. It
248 used to take it from zero actually. Changed the RNG also
249 to use /dev/urandom during session. /dev/random is used
250 in initialization. Affected file lib/silccrypt/silcrng.[ch].
252 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Changed the SILC packet header to have the first two bytes
255 (the packet length) encrypted. Affected files aroung the
256 code tree, lib/silccore/silcpacket.[ch]. Removed the
257 SilcPacketCheckDecrypt callback. It is not needed anymore
258 since the silc_packet_receive_process will determine now
259 whether the packet is normal or special.
261 * Implemented the unidirectional MAC keys. Affected files
262 lib/silcske/silcske.c, silcd/protocol.c and
263 lib/silcclient/protocol.c.
265 * Implemented the packet sequence number to the MAC computation.
266 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
267 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
268 lib/silcclient/protocol.c.
270 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
272 * Allow backup router to announce servers. All servers
273 announced by backup router are added to the global list
274 automatically. Update hte server's socket to our primary
275 router also when backup router announces a server.
276 Affected file silcd/packet_receive.c.
278 * Do not update the client->router in the function
279 silc_server_udpate_clients_by_server if the client is on
280 global list. We might fail to find any specific server
281 for locally connected clients and local cell clients. They
282 should still use the `from' and not `to' as client->router.
283 This fixes backup router resuming protocol. Affected file
286 * Decrease channel statistics count only if the channel
287 deletion worked. Affected files are silcd/server.c and
290 * Added silc_server_update_servers_by_server to update origin
291 of all server entries. Used during backup router protocol.
292 Affected files silcd/server_util.[ch], silcd/server.c. and
293 silcd/backup_router.c.
295 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
296 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
297 silc_hmac_get_hash and silc_hmac_get_name. Affected file
298 lib/silccrypt/silchmac.c.
300 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
302 * Assure that router cannot reroute the same channel message
303 to the sender. Affected file silcd/packet_receive.c.
305 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
307 * Made better checks that the channel message is not sent
308 to the router it came from. Affected file is
309 silcd/packet_send.c. Fixed memory leak too.

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

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

510 entry always, not just when the command is coming from client.
511 Affected file silcd/command.c.
513 * Added new function silc_server_packet_queue_purge to purge the
514 outgoing data queue to the network. After the function returns
515 it is guaranteed that the outgoing packet queue is empty.
516 Affected file silcd/packet_send.[ch].
518 * Purge the outgoing packet queue in the rekey protocol's final
519 callback to assure that all rekey packets go to the network
520 before quitting the protocol. Affected file silcd/server.c.
522 * Added silc_client_packet_queue_parse as similar function as
523 in server to the client library. The affected file is
524 lib/silcclient/client.c.
526 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
528 * Splitted silcd/server.c and created silcd/server_util.[ch]
529 for utility functions.
531 * Added new socket flag SILC_SF_DISABLED to indicate that the
532 connection is open but nothing can be sent to or received from
533 the connection. Affected file lib/silcutil/silsockconn.[ch].
534 The checking for disabled socket is checked in the low level
535 silc_socket_write and silc_socket_read functions.
537 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
539 * Allow only nicknames and channel names that fits into the
540 7-bit unsigned char ASCII set. Affected file silcd/command.c.
542 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
544 * When processing JOIN command reply in server check that if
545 the channel exists in our global list we'll move it the local
546 list. Affected file silcd/command_reply.c.
548 * Fixed the check whether client is joined on the channel already
549 in JOIN command. Affected file lib/silcclient/command.c.
551 * Fixed the JOIN command reply to check whether the channel
552 already exists. Affected file lib/silcclient/command_reply.c.
554 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Added silc_ske_status_string to map the SKE error numbers
557 to readable strings. The affected files are
558 lib/silcske/silcske[_status].[ch].
560 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
562 * Do not show the private channels on the WHOIS channel list
563 as it is not allowed by the protocol. The affected file is
566 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
568 * Assure that the packet length digged from the actual packet
569 is something sensible in the silc_packet_decrypt_rest_special
570 in lib/silccrypt/silcpacket.c.
572 * Free and NULL the allocated pointer in silc_hmac_alloc if
573 the HMAC allocation fails. The affected file is
574 lib/silccrypt/silchmac.c.
576 * Print the selected security properties to the log files in
577 the server. Affected file silcd/protocol.c.
579 * Add SKE's reference counter even if calling the completion
580 callback manually. Otherwise it goes negative, although it
581 does not cause any problems. The affected file is
582 lib/silcske/silcske.c.
584 * Remove the client entry with short timeout after giving the
585 KILL command. Affected file lib/silcclient/command.c.
587 * Fixed to send error reply in WHOIS and IDENTIFY commands in
588 case all found clients are already disconnected (WHOWAS would
589 found them) in the server. Affected file silcd/command.c.
591 * Update the last_receive (time of last data received) to be
592 updated only when received private or channel message so that
593 the idle time showed in WHOIS makes more sense.
595 * Added boolean field `valid' in to the SilcClientEntry in the
596 client library to indicate whether the entry is valid or not.
597 This fixes the nickname change bug on channel when changing
598 the nickname to be same than the old (like nick to Nick) the
599 nickname formatter doesn't set the new nick anymore to Nick@host.
600 Affected file lib/silcclient/idlist.[ch].
602 * Now actually fixed the nickname changing on disconnection.
603 Added new function silc_change_nick to the Irssi SILC Client.
604 Affected file irssi/src/silc/core/client_ops.c,
605 irssi/src/silc/core/silc-nicklist.[ch].
607 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
609 * Check that the public key exists in the GETKEY command before
610 trying to encode it. Affected file silcd/command.c.
612 * Print some notifications on received public keys with GETKEY
613 command in the Irssi SILC Client. Affected files are
614 irssi/src/fe-common/silc/module-formats.[ch],
615 irssi/src/silc/core/client_ops.c.
617 * Use IDENTIFY command to resolve the server information in the
618 GETKEY command instead of INFO command. Affected file
619 lib/silcclient/command.c.
621 * All command reply functions in the client library now calls
622 the pending command reply callbacks even if an error has
623 occurred. The server has done this a long time and now it was
624 time to move the client library to this as well. Now all
625 errors can be delivered back to the pending command reply
626 callbacks if necessary. Affected files are
627 lib/silcclient/command[_reply].[ch].
629 * Change the nickname on disconnection back to the username
630 because in reconnect the server will enforce it to it anyway.
631 Affected file irssi/src/silc/core/silc-servers.c.
633 * Fixed a config file parsing bug in the Irssi SILC client.
634 Affected file irssi/src/silc/core/clientconfig.c.
636 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
638 * When printing the channel mode on JOIN, verify that the
639 channel key and channel's HMAC are valid. Affected file
640 irssi/src/silc/core/client_ops.c.
642 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
644 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
645 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
646 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
648 * Removed channel key rekey task deleting from the function
649 silc_server_save_channel_key. Affected file silcd/server.c.
650 Added explicit timeout task context instead that is used to
651 delete the task if we are registering a new task before the
652 new task has elapsed.
654 * When channel key rekey occurs the client library now saves
655 the old channel key for a short period of time (10 seconds) and
656 is able to use it in case some is still sending channel
657 messages encrypted with the old key after the rekey. Affected
658 file lib/silcclient/[idlist.h|client_channel.c].
660 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
662 * Added check to the silc_server_new_id_real to not accept
663 new ID if it is the sender's own ID. Affected file is
664 silcd/packet_receive.c.
666 * Assure that we do not announce ourself or the one we've
667 sending our announcements when we're router and are announcing
668 servers to our primary router. Affected file silcd/server.c.
670 * Fixed silc_server_command_identify_check_client to assemble
671 correct WHOIS packet. It send corrupted WHOIS packet and
672 caused problem with router to router connections. Affected
673 file silcd/command.c.
675 Fixed also silc_server_command_whois_check the same way
676 as for the IDENTIFY command.
678 * Added new SilcIDListStatus to the server in the SilcIDListData
679 structure. The status now includes the current status of
680 the entry (like registered, resolved etc.). Affected file
681 silcd/idlist.[ch]. Defined a bunch of different status types
682 as well. This replaced the old boolean registered field as well.
684 Added resolve_cmd_ident field to the SilcClientEntry structure
685 too so that if the entry is for example being resolved so
686 another command may attach to the same pending command reply
687 without requiring to resolve the same entry again. This concept
688 should optimize the WHOIS and the IDENTIFY resolving under
689 heavy load by taking away unnecessary resolving for entries
690 that are being resolved already.
692 Added support for adding multiple pending commands for one
693 command idenfier. Affected file silcd/command[_reply].[ch].
695 * Fixed WHOIS and IDENTIFY save to remove the cache entry
696 before deleting the data. Otherwise the hash table will have
697 freed data in comparison functions. Affected file is
698 silcd/command_reply.c.
700 * Fixed silc_idlist_replace_client_id to add the new entry to
701 the cache with NULL nickname. Otherwise there will be invalid
702 memory as the nickname after the nickname is freed. Affected
703 file silcd/packet_receive.c.
705 * Fixed the silc_idlist_get_clients_by_hash. The entries was
706 saved into wrong slots because the previous number of entries
707 was not taken into account. Affected file silcd/idlist.c.
708 Fixed same thing in silc_idlist_get_clients_by_nickname too.
710 * If we are router and we receive JOIN notify to a channel that
711 does not have any users then notified client is marked as the
712 channel founder, as it is it. The affected file is
713 silcd/packet_receive.c
715 * Added to the extended hash table API's table_del_*ext functions
716 the destructor as argument too, so that the caller can decide
717 which destructor to use or whether to use destructor at all.
718 Affected file lib/silcutil/silchashtable.[ch].
720 * Fixed ID Cache purging. It actually deleted the entries from
721 the hash table after the data was freed. The hash table ended
722 up comparing freed memory. The affected file is
723 lib/silccore/silcidcache.c.
725 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
727 * Fixed Irssi SILC client's KILL command's HELP syntax.
729 * The USERS command now resolves the detailed user information
730 if the userinfo field is missing. Affected file is
731 lib/silcclient/command_reply.c.
733 * Do not print error in silc_file_read if the read file does
734 not exist. Just silently return NULL. Affected file is
735 lib/silcutil/silcutil.c.
737 * Fixed the silc_log_output to not wine about NULL filename
738 and to not create some bogus " " filename. Affected file is
739 lib/silcutil/silclog.c.
741 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Fixed various printing bugs on the user interface in the
744 Irssi SILC Client. Minor changes that were forgotten from
747 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
749 * Fixed the configure.in.pre and the compilation and distribution
750 environment to support the new autoconf 2.52. That version is
751 now required to compile the CVS trunk.
753 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
755 * Renamed function silc_parse_nickname to silc_parse_userfqdn
756 to generally parse user@fqdn format strings. Affected file
757 lib/silcutil/silcutil.c.
759 * Added nickname_format and nickname_force_format fields to the
760 SilcClientParams structure. The first one defines the format
761 for the nicknames that the library will enforce if the receives
762 multiple same nicknames. The second one is boolean value and
763 can be used to force the library to always enforce the format
764 to the nicknames regardles whether there are multiple nicknames
765 or not. This configurable formatting was employed to flexibly
766 support accessing multiple nicknames from the user interface.
767 The userinterface can now set the nicknames to what ever format
768 they prefer. Affected file lib/silcclient/silcapi.h.
770 Added function silc_client_nickname_format to the file
771 lib/silcclient/idlist.c. It performs the nickname formatting.
773 Added new field `hostname´ to the SilcClientEntry context.
774 It holds the hostname of the client. Affected file is
775 lib/silcclient/idlist.h.
777 * Irssi SILC Client sets the nicknames in nick@hostn format.
778 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
779 irssi/src/silc/core/silc-core.c.
781 The WHOIS printing now also shows both the real nickname and
782 the formatted nickname so that user knows how to access the
783 user if there are multiple same nicknames cached. Affected
784 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
785 printing formatting too to take the hostname now as a separate
786 argument. The Affected file is
787 irssi/src/fe-common/silc/modules-formats.[ch].
789 * Changed the silc_client_get_clients_local to accept the formatted
790 nickname as argument. It accepts the real nickname too but the
791 formatted nickname can be used to find the true entry from
792 multiple entries. Affected file lib/silcclient/silcapi.h and
793 lib/silcclient/idlist.c.
795 * Added nickname_format_parse field to the SilcClientParams.
796 It is a callback function provided by the application to parse
797 the nickname out of the formatted nickname string. The library
798 calls it to get the nickname from the formatted string. Since
799 the application generally knows better the format of the nickname
800 string it parses it instead of the library, even though library
801 encodes the formatted string. If the callback function is not
802 provided then the library will use the string as is. The
803 affected file is lib/silcclient/silcapi.h.
805 * All the nickname strings passed to the client library in
806 commands are now expected to be formatted nickname strings.
807 If the command does not support the formatted nickname string
808 it will assume that the sent string is the actual nickname.
809 Affected file lib/silcclient/command.c.
811 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Added public key authentication support to OPER and SILCOPER
814 commands in the client library. Affected file is
815 lib/silcclient/command.c.
817 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
819 * Changed the get_auth_methdod client operation to be asynchronous.
820 It can be async if the application resolves the authentication
821 method from the server during the negotiation. Added new
822 SilcGetAuthMeth completion callback that the application will
823 call after resolving the authentication method.
825 Added function silc_client_request_authentication_method that
826 the application can use to resolve the authentication method
827 from the server. Added also SilcConnectionAuthRequest callback
828 that the library will call after the server has replied. The
829 application can call this function if it does not know the
830 current authentication method.
832 Affected files are lib/silcclient/client.c and
833 lib/silcclient/silcapi.h.
835 * The Irssi SILC client now automatically resolves the authentication
836 method incase any configuration information is not present (and
837 currently there never is). The affected file is
838 irssi/src/silc/core/client_ops.c.
840 * Fixed public key authentication from the client library.
841 Affected file lib/silcclient/protocol.c. Changed also the
842 protocol specification about the public key authentication in
843 the connection authentication protocol. The actual data to be
844 signed is now computed with a hash function before signing.
846 * Fixed the public key authentication from the server as well.
847 Affected file silcd/protocol.c.
849 * Removed the mlock()'s from the memory allocation routines.
850 Affected file lib/silcutil/silcmemory.c. The ./configure does
851 not check anymore for the mlock(). Affected file is
854 * Fixed USERS command in server to allow the execution of the
855 command for private and secret channels if the client sending
856 the command is on the channel. Affected file silcd/command.c.
858 * Fixed silc_client_get_clients_local to return the clients
859 count correctly. It could return wrong value. Affected file
860 lib/silcclient/idlist.c.
862 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
864 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
865 types. The assembler optimizations seemed not to like 64-bit
866 data types. The assmebler optimizations thus are now enabled
867 also for BSD systems as opposed to only enable them for Linux.
869 * Do not check for threads at all on BSD systems. Affected
870 file configure.in.pre.
872 * Removed -n and -h options from the Irssi SILC Client since
873 they are not used in silc.
875 * Fixed the prime generation to assure that the first digit
876 of the generated random number is not zero since our conversion
877 routines does not like number strings that starts with zero
878 digit. If zero digit is seen the random number is regenerated.
879 This caused some corrupted RSA keys when the zero first digit
880 was met. Affected file lib/silcmath/silcprimegen.c.
882 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
884 * Fixed WIN32 configuration in the ./configure script.
885 Fixed to include xti.h on environments that has it.
886 Patches by Carsten Ilchmann and andrew.
888 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
890 * Changed the silc_id_create_client_id to be collision
891 resistant. It is now assured that there cannot be created
892 two same client ID's. I suspect that some weird bugs in
893 the server were actually caused by duplicate Client IDs.
894 Affected file silcd/serverid.[ch]. A router receiving
895 new ID now also assures and informs the sending server
896 if the ID caused collision.
898 * Changed the silc_id_create_channel_id to also assure that
899 there are no collisions.
901 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
903 * Statement about ignoring the Mutual Authentication flag when
904 performing rekey with PFS was a bit misleading. It is ignored
905 if it was set in the initial negotiation, it cannot be even
906 set in the rekey. Fixed in the ke-auth draft. Started the
907 new versions of the protocol drafts in the doc/.
909 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
911 * Fixed a bug in silc_client_command_identify_save when saving
912 new channel information. The channel name was no duplicated
913 and caused crash on exit. Affected file is
914 lib/silcclient/command_reply.c.
916 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
918 * Fixed the getkey command handling in the server. Send just
919 empty OK reply to the sender if the key could not be fetched
920 (but everything else was ok, like the key just was not available).
921 Changed the public key parameter to optional in the protocol
922 specs so that empty OK reply can be sent. Affected file
925 Added a message to Irssi SILC client to tell to user if the
926 server did not return a public key.
928 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Fixed a channel key regeneration bug. It registered new
931 timeout tasks exponentially until all system resources were
932 used. Affected file silcd/server.c.
934 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
936 * Added the SILC Document generator to the scripts/silcdoc.
937 It can be used to generate the Toolkit Reference Manual out
938 of the source tree. Internally it will also use the RoboDoc
939 generator now imported in util/robodoc.
941 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
943 * Added couple of return's in rekey protocol if error orccurred
944 during the protocol. The execution must be terminated.
945 Affected file silcd/protocol.c. Also, terminate the protocol
948 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * The client's Client ID was created initally from the wrong
951 nickname (it could have been in format nick@host) in the
952 silc_server_new_client. Affected file silcd/packet_receive.c
954 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Added some SILC_LOG_ERROR's to various error conditions
957 if client could not be added to ID cache. Affected files
958 silcd/packet_receive.c and silcd/server.c.
960 * When client's sock->user_data is freed, NULL also the
961 client->router and client->connection pointers. Added check
962 for these pointers being NULL to various places around the
963 code. Affected file silcd/server.c.
965 * Added client->data.registered == TRUE checks to various
966 places around the code to assure that unregistered client's
967 are not handled when it is not allowed. Affected file
970 * Added `bool registered' fields to all
971 silc_idlist_[server|client]_get_* routines to indicate whether
972 the fetched client needs to be registered or not. Affected
973 file silcd/idlist.[ch].
975 * Add your own entry as registered to the ID cache in the
976 server. Affected file server.c.
978 * Fixed a bug in silc_server_new_server. The SilcServer was
979 set as the new server's context instead of SilcServerEntry.
980 This naturally caused some weird bugs.
982 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
984 * Do not delete the channel rekey task when adding it
985 for in silc_server_create_channel_key.
987 * Changed the silc_server_create_channel_key to return
988 TRUE or FALSE to indicate the success of the channel key
991 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
993 * Fixed MSVC++ project files and added missing files to
994 Makefiles under win32/.
996 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
998 * Do not add TCP_NODELAY flag if the operating system
999 does not have it defined. Affected files are
1000 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1002 * Fixed buffer overflow from Irssi SILC Client. Affected
1003 file irssi/src/fe-common/core/themes.c.
1005 * Fixed double free in client library in the file
1006 lib/silcclient/client.c when disconnecting from server.
1008 * Applied double free patch from cras to Irssi SILC client.
1009 Affected files irssi/src/core/[modules/expandos].c
1011 * Fixed the disconnection handling to Irssi SILC Client.
1012 The application must call silc_client_close_connection
1013 in ops->connect client operation in case of failure of
1014 the connection. Affected file is
1015 irssi/src/silc/core/client_ops.c.
1017 * Do not set sock->protocol to NULL in the function
1018 silc_client_close_connection after executing the protocol's
1019 final callback since the sock might not be valid anymore.
1020 Affected file lib/silcclient/client.c.
1022 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Do not enable SILC_THREADS if the linking with libpthread
1025 did not happen. Affected file configure.in.pre.
1027 * Added notion to protocol specification that server must
1028 verify the sent authentication payload with CMODE when
1029 setting the channel founder key. Implemented it to the
1030 server. Affected file silcd/command.c.
1032 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Added _EXTRA_DIST SILC distribution variable to the
1035 distributions file. It is used to conditionally add extra
1036 files or directories to the specific distribution. Affected
1037 files ./prepare, Makefile.am.pre and distributions.
1039 Removed the `_' from the start of the distribution names.
1042 * Added README.WIN32 for instructions to compile the Toolkit
1045 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1047 * Fixed a double free in disconnection in the server. Affected
1048 file is silcd/server.c.
1050 * Fixed the lib/silcske/groups.c to work now also with GMP
1051 MP library. The string conversion did not work when using
1052 specific base and the base is indicated in the string as well.
1054 * Created win32/ directory which now includes MSVC++ specific
1055 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1056 It will appear only in the toolkit distribution
1058 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1060 * Changed the key material distribution function in case when
1061 the hash output is too short. The data is now concatenated
1062 a bit differently than it used to. Made the change to the
1063 SKE protocol specification.
1065 * Added better GMP detection to configure.in.pre. A patch
1068 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1070 * Fixed a minor bug in SKE that might cause some problem on
1071 some platforms. Affected file lib/silcske/silcske.c.
1073 * Added the cookie checking for initiator in the SKE. It checks
1074 that the responder returns the sent cookie unmodified. The
1075 affected file is lib/silcske/silcske.c. Added new SKE
1076 error type INVALID_COOKIE that can be sent during the
1077 negotiation. Fixed some memory leaks as well.
1079 * Added the "invalid cookie" error message to Irssi SILC client's
1082 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1084 * Added `task_max' field to the SilcClientParams to indicate
1085 the maximum tasks the scheduler can handle. If set to zero,
1086 default values are used. Affected file lib/silcclient/silcapi.h.
1088 * Fixed memory leaks in silc_client_close_connection. Affected
1089 file lib/silcclient/client.c.
1091 * Added silc_client_del_client_entry to client library to free
1092 all memory of given client entry. Affected file is
1093 lib/silcclient/idlist.[ch].
1095 * Added new functions silc_client_del_channel and
1096 silc_client_del_server to delete channel and server entries.
1097 Affected file lib/silcclient/[silcapi.h/idlist.c].
1099 * Removed silc_client_del_client_by_id from silcapi.h.
1101 * Fixed the INFO command to return the server's own info
1102 correctly when querying by Server ID. Affected file is
1105 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1107 * Removed the non-blocking settings in WIN32 code in the
1108 silc_sock_[read/write] and added SleepEx instead. Affected
1109 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1110 of input data is now checked with FIONREAD and ioctlsocket.
1112 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1114 * Call silc_schedule_task_del_by_context in the
1115 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1116 Affected file lib/silccore/silcprotocol.c.
1118 * Call silc_protocol_cancel for active protocols in the
1119 silc_server_close_connection if the funtion
1120 silc_server_free_sock_user_data has not been called.
1121 Affected file silcd/server.c.
1123 * Generic tasks cannot be deleted using the del_by_fd
1124 task deleting function since generic tasks does not match
1125 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1127 * Added a notion to SILCOPER help file that the SILCOPER works
1128 only on router server, not on normal server.
1130 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1132 * Added for WIN32 support for the new scheduler as well.
1133 Affected file lib/silcutil/win32/silcwin32schedule.c.
1135 * Fixed the SHA1 implementation to work on various platforms.
1137 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1139 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1140 API. It is part of the scheduler now. Everything else is
1141 as previously but some functions has changed their names.
1142 Checkout the lib/silcutil/silcschedule.h for the interface.
1143 Updated all applications to use the new interface. Affected
1144 files are lib/silcutil/silcschedule.[ch].
1146 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Found a bug in the SKE implementation. The HASH value,
1149 specified by the protocol, was not computed correctly. The
1150 public key of the responder was not added to the computation
1151 even though it is mandatory. Affected file lib/silcske/silcske.c.
1152 This unfortunately causes incompatibilities with older
1153 clients and servers.
1155 * Added WIN32 specific network init and uninit functions:
1156 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1157 the Winsock2. Affected file lib/silcutil/silcnet.h and
1158 lib/silcutil/win32/silcwin32net.c.
1160 * Set the socket always to nonblocking mode on WIN32 after
1161 reading data or writing data. Affected file is
1162 lib/silcutil/win32/silcwin32sockconn.c.
1164 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1166 * Fixed various compilation problems under WIN32. Affected
1167 files lib/silcutil/win32/silcwin32thread.c and
1168 lib/silcutil/win32/silcwin32schedule.c.
1170 * Removed all _internal.h #includes from public header
1171 files. Internal headers must never be included from
1174 Removed also the lib/silcske/payload_internal.h file.
1176 * All include files that may be needed (public and some others
1177 included by the public headers) by application developers are
1178 now copied to the ./includes directory. It does not copy any
1179 internal headers. Affected file Makefile.defines.pre and all
1180 Makefile.am's under lib/ and subdirs.
1182 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1184 * Do not change the ~/.silc directory's permissions automatically.
1185 Affected file irssi/src/silc/core/clientutil.c.
1187 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * Do not cancel the protocol in silc_server_close_connection
1190 it might cause recursion. Now cancelled in the function
1191 silc_server_free_sock_user_data. Affected file silcd/server.c.
1193 * Fixed the silc_server_remove_clients_by_server to regenerate
1194 the channel keys correctly finally. Added also new function
1195 silc_server_remove_clients_channels to actually do it.
1196 Affected file silcd/server.c.
1198 * Fixed the silc_server_new_channel to not crash by giving
1199 wrong router to the new channel. Affected file is
1200 silcd/packet_receive.c.
1202 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1205 which is given as argument to the silc_client_alloc now.
1206 It can be used to configure the client and set various parameters
1207 that affect the function of the client.
1209 * The USERS command in server did not check whether the channel
1210 is private or secret. Affected file silcd/command.c.
1212 * Added new argument to the USERS command in protocol specification.
1213 The USERS command now can take the channel name as argument
1214 as well. Added support for this in client and server and
1215 updated the protocol specs.
1217 * Completed the GETKEY command in client. It can be now used
1218 to fetch also servers public key not only some clients.
1219 Affected files lib/silcclient/command[_reply].c.
1221 * Added silc_client_get_server to return server entry by the
1222 server name. Affected files lib/silcclient/silcapi.h and
1225 * Redefined the IDENTIFY command in protocol specification to be
1226 more generic. It now can be used to query information about
1227 any entity in the SILC Network, including clients, servers and
1228 channels. The query may be based either the entity's name
1229 or the ID. Added support for this in both client and server.
1231 Affected files silcd/command.c and lib/silcclient/command.c
1232 and command_reply.c.
1234 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1235 the _from_client and _from_server functions. Affected file
1238 * Added silc_client_get_channel_by_id_resolve to the file
1239 lib/silcclient/silcapi.h to resolve channel information by
1240 its ID. Added also silc_client_get_channel_by_id that
1241 does not resolve it from the server.
1243 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * Added SilcServerEntry context into the client library
1246 to represent one server. The INFO command now allocates
1247 these to save the resolved server info. For now on the
1248 client library will also keep information about servers,
1249 connected and resolved with INFO.
1251 The INFO command now allocates the SilcServerEntry context
1252 and saves the server info there. The COMMAND_REPLY in
1253 the INFO now returns the parameters to application in
1254 same order as defined in the protocol specification.
1256 The entries are cached in the client->server_cache.
1258 * The INFO command is now issued after received the Client ID
1259 from the server. Affected file lib/silcclient/client.c.
1261 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1262 to the application as the mode changer might be server.
1263 It is guaranteed that NULL is not returned anymore to the
1264 application. Affected file lib/silcclient/client_notify.c.
1266 The ID Type is now also passed to the application so that
1267 it can check whether the returned entry is SilcClientEntry
1270 Added new function silc_client_get_server_by_id to return
1271 the server entry by ID. Affected files are the
1272 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1274 * Do not create the channel in the Irssi SILC Client when issuing
1275 the JOIN command but when received the sucessful JOIN command
1276 reply. Otherwise the channel might get created even though we
1277 could not join it. The Affected file is
1278 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1280 * Fixed a channel joining bug in router. The router must also
1281 check the channel modes, invite and ban lists etc. when serving
1282 the JOIN command sent by normal server. Affected file is
1283 silcd/command.c. The router now resolves the client's
1284 information from the server who sent the JOIN command if it
1285 does not know it, and processes the JOIN command only after
1288 * Changed the SilcCommandCb to take new argument; void *context2.
1289 Affected file lib/silccore/silccommand.h
1291 The second argument in the command callbacks in the server now
1292 includes the SilcServerCommandReplyContext if the command was
1293 called as pending command callback from the command reply.
1294 Otherwise it is NULL. When called as pending the status of the
1295 command reply will be checked and if it was erronous the
1296 error will be sent to the original sender of the command.
1297 This way the client always receives the error messages even
1298 though the server was actually the one who received the error
1299 when it resent the command to router, for example. Affected
1300 files silcd/command[_reply].[ch].
1302 * Fixed sending WHOWAS command's error message to client if
1303 the requested client could not be found. It was missing.
1306 * Changed the CMODE and CUMODE commands reply arguments in the
1307 protocol specification. The Channel ID is now sent in both
1308 of the commands to identify the channel. Implemented this
1309 new feature to the client and server. Affected files
1310 lib/silcclient/command_reply.c and silcd/command.c.
1312 * Made better checks for invite and ban lists in the JOIN
1313 command in server. Affected file silcd/command.c.
1315 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1317 * The server now performs the incoming host IP/DNS lookup
1318 using the silc_socket_host_lookup and thus does not block
1319 the server anymore. Affected file silcd/server.c.
1321 * Completed the multi-thread support for SILC Scheduler in
1322 the lib/silcutil/silcschedule.c.
1324 * Fixed the configure.in.pre to detect the pthread correctly
1327 * Fixed a deadlock in silc_task_queue_wakeup in the file
1328 lib/silcutil/silctask.c.
1330 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * Added new function silc_schedule_wakeup that is used in
1333 multi-threaded environment to wakeup the main thread's
1334 schduler. It needs to be used when a thread adds a new task
1335 or removes a task from task queues. After waking up, the
1336 scheduler will detect the task queue changes. If threads
1337 support is not compiled in this function has no effect.
1338 Implemented the wakeup mechanism to both Unix and WIN32
1339 systems. Affected files are lib/silcutil/silcschedule.[ch],
1340 lib/silcutil/unix/silcunixschedule.c and the
1341 lib/silcutil/win32/silcwin32schedule.c.
1343 * Added new function silc_task_queue_wakeup to wakeup the
1344 scheduler by the specified task queue. Affected file
1345 lib/silcutil/silctask.[ch].
1347 * The silc_socket_host_lookup_start now wakes up the scheduler
1348 after adding the timeout task. Affected file is
1349 lib/silcutil/silcsockconn.c.
1351 * The silc_socket_host_lookup is synchronous now if the threads
1352 support is not compiled in. However, the callback is still
1353 called asyncronously through the scheduler, anyway. Affected
1354 file lib/silcutil/silcsockconn.c.
1356 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Added new function silc_socket_host_lookup to perform
1359 asynchronous IP and FQDN lookups for the socket connection.
1360 Affected files lib/silcutil/silcsockconn.[ch].
1362 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1364 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1365 that may or may not compile the mutex support in.
1367 Changed the silc_mutex_alloc interface. It allocates the
1368 mutex now to the sent pointer and returns TRUE or FALSE.
1370 Affected file lib/silcutil/silcmutex.h.
1372 * Wrote the SILC Task Queue interface to support multi-threads.
1373 Affected file lib/silcutil/silctask.[ch].
1375 * Wrote the SILC Scheduler to support multi-threads. Affected
1376 file lib/silcutil/silcschedule.c.
1378 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1381 in lib/silcutil/win32/.
1383 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Defined SILC Mutex API and SILC Thread API and implemented
1386 them for Unix. Affected files are
1387 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1388 lib/silcutil/unix/silcunixmutex.c and
1389 lib/silcutil/unix/silcunixthread.c.
1391 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1393 * Fixed the silc_server_remove_clients_by_server's channel
1394 key re-generation. The hash table handling was incorrect
1395 and would not work with many channels. Affected file is
1398 * Fixed some memory leaks around the server code.
1400 * Rewrote the silc_server_get_users_on_channel to support IPv6
1401 based Client ID's. Affected file silcd/server.c.
1403 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1404 specification. However, a separate document must be written
1405 to define the detailed signing procedure and the payload
1406 associated with the flag. Defined the flag to the
1407 lib/silccore/silcchannel.h as well.
1409 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1411 * Changed the dynamic tables to static size tables in the
1412 lib/silccrypt/silchmac.c.
1414 * Removed GCC dependencies from the code. A patch by cras.
1416 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Do not show the error "Error receiving packet bla bla"
1419 in server if it really was not an error (-2 means that reading
1420 is pending). Affected file silcd/server.c.
1422 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1424 * Fixed a possible crash in silc_server_remove_clients_by_server
1425 in silcd/server.c. Fixed there also some memory leaks.
1427 * Fixed the silc_idlist_replace_client_id. It could replace
1428 wrong key in the hash table. Affected file silcd/idlist.c.
1430 * Do not check whether there are global users on the channel
1431 if the channel->global_users is FALSE. Affected functions
1432 silc_server_remove_from_one_channel and
1433 silc_server_remove_from_channels in silcd/server.c. Also,
1434 do not check if the removed client is local as we can be
1435 sure that global client was not removed from the channel
1436 and checking for global users is not needed.
1438 * The silc_server_remove_clients_by_server now re-generates
1439 the channel keys correctly for those channels that had
1440 clients removed from them. Affected file silcd/server.c.
1442 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Found the reason of random crashes in the server. We weren't
1445 ignoring the SIGPIPE signal (which can be sent in write())
1446 and it crashed the server. Affected file silcd/silcd.c.
1448 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Assure that sock->user_data is not NULL in the function
1451 silc_server_packet_send in silcd/packet_send.c.
1453 * Disconnect the remote connection if it could not be added
1454 to any ID lists in the server. The affected file is
1457 * Check in silc_server_packet_send[_real/dest] that the
1458 socket is not disconnecting and ignore the data if it is.
1459 Affected file silcd/packet_send.c.
1461 * Define inline to __inline on native WIN32 compilation.
1462 Affected file includes/silcwin32.h.
1464 * Added some explicit type casts for inline code since MSVC
1465 require them. Affected files lib/silcutil/silcbuffer.h,
1466 lib/trq/silcdlist.h and lib/trq/silclist.h.
1468 * Print warning in log files from now on if the packet
1469 decryption fails. Affected file silcd/server.c.
1471 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1473 * Changed the `say' client operation's interface to accept
1474 new `type' argument to indicate the type of the message sent
1475 by the library. The application may filter the library's
1476 messages according the type. The affected file is the
1477 lib/silcclient/silcapi.h.
1479 * Added two new functions to lib/silcclient/silcapi.h:
1480 silc_client_del_client and silc_client_del_client_by_id.
1481 Affected file lib/silcclient/idlist.c.
1483 * Moved the clientincludes.h from includes/ to silc/ and
1484 serverincludes.h from includes/ to silcd/.
1486 * The modes for the CMODE and CUMODE are now passed as
1487 uint32 for application with COMMAND_REPLY. The affected
1488 file is lib/silcclient/command_reply.c.
1490 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * /WHOIS without arguments shows client's own information.
1493 Affected file lib/silcclient/command.c.
1495 * Changed PING to not accept any arguments. The specs
1496 says that client can ping only the connected server so
1497 requiring an argument is not needed. Affected file is
1498 lib/silcclient/command.c.
1500 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Fixed a fatal bug in private message sending and reception
1503 encryption and decryption when using private message keys.
1504 The implementation was incorrect and did not follow the
1505 specification. It causd that some of the message were
1506 lost since it did not use the sending and receiving keys
1507 as the protocol suggests. This has been fixed and will cause
1508 incompatibilities with older clients when sending private
1509 message encrypted with private message keys. Affected files
1510 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1511 and various other in Irssi SILC Client.
1513 Added `responder' boolean argument to the functions
1514 silc_client_add_private_message_key[_ske] to indicate when
1515 the key is added as responder or initiator of the key
1518 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1520 * Removed the silc_ske_check_version function and created
1521 a SilcSKECheckVersion callback. Added also a function
1522 silc_ske_set_callbacks that is now used to set all SKE
1523 callbacks. The callback functions are not given to
1524 the SKE functions anymore, but this function is used to
1527 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1529 * Added `silc_version' argument to the silc_client_alloc
1530 to define the version of the application for the library.
1531 The library will use the version string to compare it
1532 against the remote host's (usually a server) version
1533 string. Affected file lib/silcclient/silcapi.h
1535 * Added the KE protocol context to Key Agreement context
1536 in client library so that we can abort the SKE if it
1537 is in process when we get timeout. Affected file is
1538 lib/silcclient/client_keyagr.c.
1540 * Do not resolve the client ID forever if it returns in the
1541 first time that such client does not exist. This was done
1542 for example with private message. Affected file is
1543 lib/silcclient/client_prvmsg.c.
1545 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1547 * Do not add regex.h for WIN32. The affected file
1548 includes/silcincludes.h.
1550 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1551 not work yet 100%. It generates the DLL's automatically
1552 when compiling with --with-win32 under cygwin.
1554 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * lib/contrib/regex.c is not compiled on WIN32.
1558 * Added silc_net_get_socket_opt function to the
1559 lib/silcutil/silcnet.h.
1561 * Added includes/silcwin32.h for WIN32 specific includes
1564 * Do not use ptime structure or any of the posix process
1565 functions on WIN32 in lib/silccrypt/silrng.c.
1567 * Added silc_gettimeofday to provide generic function
1568 for struct timeval on all platforms. Added the function
1569 to lib/silcutil/silcutil.h.
1571 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1573 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1574 library as they clearly belong there. As a plus side we
1575 can make the actual socket connection routines platform
1578 Added also new generic function silc_socket_read and
1579 silc_socket_write (that used to be silc_packet_[read/write].
1580 The implementation of these are platform specific.
1582 * Added WIN32 specific routines of silc_socket_[read/write]
1583 to lib/silcutil/win32/silcwin32sockconn.c.
1585 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1587 * Added preliminary support for native WIN32 compilation under
1588 cygwin (using the -mno-cygwin option for GCC) to the
1589 ./configure.in.pre. The --with-win32 now prepares the
1590 compilation for native WIN32.
1592 * Rewrote the SILC Scheduler interface in the file
1593 lib/silcutil/silcschedule.h. The scheduler is now context
1594 based and does not have anymore any global static scheduler.
1595 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1596 and created lib/silcutil/win32 directory for WIN32 based
1599 * Added Unix specific network routines to the
1600 lib/silcutil/unix/silcunixnet.c and the old
1601 lib/silcutil/silcnet.c includes now only generic routines.
1603 Added WIN32 specific network routines to the
1604 lib/silcutil/win32/silcwin32net.c.
1606 * Added Unix specific utility functions from the
1607 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1609 * Added WIN32 SILC Scheduler to the file
1610 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1613 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1615 * Do not handle JOIN notify in the server if the target client
1616 is not registered (idata->registered == FALSE). The affected
1617 file is silcd/packet_receive.c.
1619 * Update the nickrec->founder in event_cumode in the Irssi SILC
1620 client. Affected file irssi/src/silc/core/silc-channels.c.
1622 * Fixed the CUMODE_CHANGE notify handling in the server when
1623 server and router are announcing their clients on channels.
1624 Now the mode changes are saved and notified correctly. The
1625 affected file is /silcd/packet_receive.c.
1627 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1628 They really did not replace the cache entry in the ID Cache.
1629 Now they do that. Affected file silcd/idlist.c.
1631 * Fixed the KICK notify handling in the Irssi SILC client to
1632 update the channel records so that the kicked client does not
1633 appear to be on the channel. The affected file is
1634 irssi/src/silc/core/silc-channels.c.
1636 * Always update the conn->current_channel when executing command
1637 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1639 * Fixed the KILL notify handling in Irssi SILC client to remove
1640 the killed client on all channels.
1642 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1644 * Fixed the silc_parse_command_line to remove extra spaces
1645 from the start and end of the arguments. Affected file is
1646 lib/silcutil/silcutil.c.
1648 * Cancel and free any active protocol in the function
1649 silc_server_close_connection. Affected file silcd/server.c.
1651 * Cancel and free any active protocol in the function
1652 silc_client_close_connction. Affected file is
1653 lib/silcclient/client.c.
1655 * Do not execute the KILL command for clients that are in
1656 history (ie. they are not in the network). Affected file is
1659 * Fixed KILL notify handling, client does not crash anymore.
1660 Affected file irssi/src/silc/core/silc-channels.c.
1662 * Reduced the default packet buffer size from 2048 to 1024 in
1663 lib/silccore/silcpacket.c.
1665 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1666 counter to the SKE context that is incresed when the SKE library
1667 performs async operation outside the library. If the outside
1668 process frees the SKE context and FREED status will be set
1669 and the library will detect after the sync operation that the
1670 libary is freed. The affected files are
1671 lib/silcske/silcske[_status].[ch].
1673 * Resolve the client entry information in the function
1674 silc_client_channel_message to assure that NULL pointer is not
1675 passed as client entry to the application. */
1677 * Fixed the task timeout calculation to assure that there is
1678 never negative timeouts. The affected file is
1679 lib/silcutil/silcschedule.c.
1681 * Fixed the channel user mode notification sending in server.
1682 It was sent point-to-point to the router (or to server by router)
1683 but it needs to be destined to a channel. The routines now
1684 supports sending the channel user mode notifys to the channels
1685 when announcing clients and channels. Affected files are
1686 silcd/server.c and silcd/packet_receive.c.
1688 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1689 It did not actually replace the old channel entry in the cache.
1690 Affected file lib/silcclient/client_notify.c.
1692 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Fixed a possible crash in silc_packet_send_prepare. It now
1695 assures always that there is enough space in the buffer and
1696 at the tail area of the buffer (for MAC).
1698 Fixed the inbound buffer reallocation in silc_packet_read.
1699 It was old code and did not handle the reallocation correctly.
1702 The affected file is lib/silccore/silcpacket.c.
1704 * Fixed buffer overflow in silc_parse_nickname in the file
1705 lib/silcutil/silcutil.c.
1707 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * make install generates new server keys only if there is not
1712 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1715 Added check that if the NOREPLY is set then we will not send
1716 the away message. This avoids infinite loop of away messages
1717 if both clients are away. The affected file is
1718 lib/silcclient/client_prvmsg.c.
1720 * Fixed client crash if /NICK was given without arguments.
1721 Affected file lib/silcclient/command.c.
1723 * Server does not send the invite list in INVITE command back
1724 to the client if the list was not altered. Added this notion
1725 to the protocol spec as well. Affected file silcd/command.c.
1727 Fixed possible crash in INVITE command by checking the
1728 value of silc_server_get_client_route command.
1730 * Fixed the INVITE notify type handling. The arguments are now
1731 taken in correct order and client does not crash. The affected
1732 file is irssi/src/silc/core/silc-channels.c.
1734 Removed the "Inviting xxx to channel" message from the
1735 client library away and let the application handle it.
1736 Affected file lib/silcclient/command.c. Added that message
1737 to Irssi SILC client's message formats.
1739 * Fixed CMODE command crash in client. It now checks the
1740 amount of arguments correctly and does not crash. The affected
1741 file is lib/silcclient/command.c.
1743 * Do not create new channel automatically in silc_channels_join
1744 but check whether the channel by that name already exists.
1745 Affected file irssi/silc/core/silc-channels.c.
1747 * Do not send the SERVER_SIGNOFF to router if the disconnected
1748 entity was the router. Affected file silcd/server.c.
1750 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1751 SILC client as it was missing from there.
1753 Added the handling of the KICK notify to the Irssi SILC client
1754 as it was missing. Added "you have been kicked" message to
1755 Irssi SILC client's message modules formats.
1757 Added the handing of the KILL notify to the Irssi SILC client
1758 as it was missing. Added the kill message module formats
1761 The affected file is irssi/src/silc/core/silc-channels.c.
1763 * The router did not save the channel mode the server announced.
1764 Affected file silcd/packet_receive.c.
1766 * Fixed a possible crash in INFO command in server. If the
1767 server did not provide the server info it crashed. Affected
1768 file silcd/command.c.
1770 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Fixed the GETKEY command in the server to check also the
1773 global list. Otherwise the GETKEY would not work correctly
1774 in normal SILC server. Affected file silcd/command.c.
1776 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Fixed GETKEY crash, it crashed if the command did not succseed.
1780 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1783 is now real and not just an macro interface to GMP.
1785 Removed the entire GMP from the source tree and imported new
1786 NSS MPI library instead. Reason for removing GMP is that it is
1787 extremely large and compiles extremely slow. The NSS MPI
1788 is only a few files and compiles in less than 10 seconds.
1789 The speed is also about the same as GMP. The MPI is imported
1790 to lib/silcmath/mpi.
1792 If the system has GMP installed we will still use the GMP.
1793 If it is not then the NSS MPI will be compiled.
1795 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1797 * Merged a long nickname (127 characters long) crash bugfix from
1798 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1800 * Merged a freed memory reference bugfix from Irssi CVS tree.
1801 Affected file irssi/src/core/commands.c.
1803 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Added the server's public key sving and verification to the
1806 server when performing the SKE. This was missing and the
1807 remote server's (or router's) public key was accepted without
1808 checking whether we have it previously or trust it at all.
1809 Affected file silcd/protocol.c.
1811 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Check in the silc_server_timeout_remote if protocol is active
1814 and make sure that the protocol's final callback is called so
1815 that all memory if freed. Affected file silcd/server.c.
1817 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * silc_server_whois_send_reply crashed the server if the nickname
1820 was 127 characters long. Affected file silcd/command.c.
1822 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Added sanity check to the silc_server_new_client. If the hostname
1825 is provided inside username then check that the provided hostname
1826 really is the same as the resolved one. If the hostname was not
1827 resolved then check it from the public key. Affected file is
1828 silcd/packet_receive.c.
1830 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1831 if the server disconnected us and the connection is not valid
1832 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1834 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1835 the library to the lib/silcutil/silcutil.[ch].
1837 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * Close log file after open. Affected file
1840 lib/silcutil/silclog.c.
1842 * Check whether sock == NULL in silc_client_send_packet and return
1843 if it is. Affected file lib/silcclient/silcclient.c.
1845 * Check rec->entry == NULL in the Irssi SILC Client before
1846 sending the channel message. Affecte file is
1847 irssi/src/silc/core/silc-servers.c.
1849 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Merged a splitted window bugfix from Irssi CVS tree. The
1852 affected file is irssi/src/fe-text/textbuffer-view.c.
1854 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1855 It did not print nickname.
1857 * Improved the distributions system a bit.
1859 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1861 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1862 irssi/src/fe-text/gui-window.c.
1864 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1865 to in-active server. The affected file is
1866 irssi/src/silc/core/client_ops.c.
1868 * Resolve the client in USERS command reply if the entry does
1869 not have username resolved. The affected file is
1870 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1871 command to WHOIS command to really resolve stuff. The USERS
1872 is not used any more in any critical section so WHOIS can
1873 be used even though it might be slower than IDENTIFY.
1875 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1878 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Changed the protocol API a bit more consistent in the
1881 lib/silccore/silcprotocol.[ch].
1883 * Changed the following headers to ROBODoc format:
1885 lib/silccore/silcpayload.h
1886 lib/silccore/silcprotocol.h
1887 lib/silccore/silcsockconn.h
1889 All core library headers are now formatted.
1891 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Fixed a bug in Irssi SILC client; do not show that you are
1894 server/router operator if you really are not. Affected file is
1895 irssi/src/silc/core/client_ops.c.
1897 * Renamed silc_command_free_payload to silc_command_payload_free.
1898 Affected file lib/silccore/silccommand.h
1900 * Added silcmath.h to include the prototoypes of various routines
1901 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1904 * Changed the following headers to ROBODoc format:
1906 lib/silccore/silcchannel.h
1907 lib/silccore/silccommand.h
1908 lib/silccore/silcid.h
1909 lib/silccore/silcidcache.h
1910 lib/silccore/silcmode.h
1911 lib/silccore/silcnotify.h
1912 lib/silccore/silcpacket.h
1913 lib/silcmath/silcmath.h
1915 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * Added checking to the server code not to start the server if
1918 ciphers and stuff are not configured properly. Affected files
1919 silcd/serverconfig.[h] and silcd/server.c.
1921 * Changed the layout of the header files of the public interfaces
1922 in the SILC libraries. The new layout supports ROBODoc
1923 documentation tool (and some others) so that it is easy to create
1924 a library reference manual. All the other headers and source
1925 code must still follow the CodingStyle document. Also source
1926 code must not include these ROBODoc stuffs, only the headers.
1927 Furthermore, all public interface headers must now be named
1928 by using `silc' prefix, example: silcapi.h, silccipher.h.
1929 Some files were renamed due to this. All the other headers
1930 must not be used as public interfaces. I will update the
1931 CodingStyle document later. Changed following headers, so far:
1933 lib/silcclient/silcapi.h
1934 lib/silccore/silcauth.h
1935 lib/silccore/silcprivate.h
1936 lib/silccrypt/silcdh.h
1938 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1942 * Removed silc_client_packet_send_flush from the client library
1943 as it is not needed. Affected file lib/silcclient/client.[ch].
1945 * Added printing of message of unresolved authentication method
1946 to the Irssi SILC client. Added it to the module formats.
1947 Removed the same message from the client library.
1949 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Added new distribution feature, DISTLABEL. Every distribution
1952 can define own preprocessor label that can be used in the
1953 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1954 file distributions, acconfig.h.pre and prepare.
1956 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Added Makefile.defines_int to include the actual definitions
1959 for Makefile.defines.in. Tested the new distribution system,
1960 created distributions and tested installation.
1962 * Added AWAY message printing to the Irssi SILC client. Added
1963 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1965 * Added SCONNECT command to call the SILC's CONNECT command.
1966 Cannot use CONNECT directly since Irssi uses that internally.
1967 Affected file irssi/src/silc/core/silc-servers.c.
1969 Added ACTION local command. It is same as ME command but takes
1970 the channel as mandatory argument.
1972 Rewrote some of the Irssi's help files to suite for SILC
1975 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Added Makefile.defines[.in] that should for now on be included
1978 in all Makefile.am file in the source tree. That file includes
1979 all common compilation definitions for SILC source tree.
1981 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Minor changes to the ./prepare script to change the package
1984 name according the distribution name to the configure.in.
1986 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Created new distribution system. Added file `distributions'
1989 that defines all the distributions that can be created out of
1990 the SILC source tree. The ./prepare script now reads that
1991 file to determine how to prepare the distributions. The
1992 first argument to the ./prepare is the name of the distribution
1993 and second is the version of the distribution. If given
1994 without arguments it creates the default (toolkit) distribution
1995 with the default version (defined in ./prepare).
1997 All Makefile.am files that are subject to the distributions
1998 are now named as Makefile.am.pre. These are ./Makefile.am
1999 and lib/Makefile.am. Others may be changed later.
2001 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Added invite list, ban list, some key management and connection
2004 error message printing to module formats in the Irssi SILC client.
2006 * Added new silc_client_set_away_message to set the away message
2007 that is back to the person who sent private message. The
2008 affected file lib/silcclient/silcapi.h and the
2009 lib/silcclient/client_prvmsg.c.
2011 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Fixed the private message sending in the Irssi SILC client,
2014 added local command KEY to the Irssi SILC client.
2016 Added key management and key agreement message formats to the
2017 irssi/src/fe-common/silc/module-formats.[ch].
2019 Added USERS (alias WHO) printing, server/router operator
2020 indication and LIST command printing to the module formats.
2022 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Fixed channel joining notify handling, cumode notify handling
2025 from Irssi SILC client.
2027 * Added SILC specific module-formats to the Irssi SILC client so
2028 that SILC specific message hilighting, colors etc is possible.
2029 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2031 Added channel mode, channel user mode, actions, notices,
2032 whois and whowas printing to the the module-formats.c.
2034 * Fixed a bug in channel deletion in the server. The channel
2035 is not left to the cache even if the channel founder auth mode
2036 is set when there are no users anymore on the channel. Affected
2037 file silcd/server.c.
2039 * The silc_net_localhost now resolves the entire hostname including
2040 the domain name. Affected file lib/silcutil/silcnet.c.
2042 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Changed the ask_passphrase client operation to be ascynchronous.
2045 It has now a completion callback and a context that the
2046 application must call after it has got the passphrase from
2047 the user. Affected files lib/silcclient/silcapi.h,
2048 lib/silcclient/protocol.c, lib/silcclient/command.c and
2051 Added SilcAskPassphrase callback that the application calls
2052 to deliver the passphrase to the library.
2054 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2055 The public key verification and especially a certificate
2056 verification is asynchronous procedure.
2058 Added new SILC_SKE_STATUS_PENDING status to indicate the
2059 request is pending and a callback will be called to finalize
2062 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2063 indicate that remote end did not send its public key (or
2064 certificate), even though we require it. Added check for this
2065 condition in the SKE. This was a security bug, now fixed.
2067 Defined new SilcSKEVerifyCbCompletion callback that is called
2068 when the verification process is completed.
2070 The affected files lib/silcske/silcske_status.h and
2071 lib/silcske/silcske.[ch].
2073 * Changed the verify_public_key client operation to be async
2074 as well. Defined SilcVerifyPublicKey callback that is used to
2075 indicate the success of the public key verification process.
2077 Changed the server and client to use the new async client
2080 * Changed the Irssi SILC client's internal scheduler to be called
2081 twice as many times as it used to be. As a result the client
2082 should be a bit faster now. Affected file is
2083 irssi/src/silc/core/silc-core.c.
2085 * Added support to Irssi SILC client of asynchronous public key
2086 verification and passphrase inquiry. Affected file is
2087 irssi/src/silc/core/silc-core.c.
2089 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Do not say "You have left channel %s" in client library.
2092 Moved it to the application. Affected files are
2093 lib/silcclient/command.c and silc/client_ops.c.
2095 * Fixed silc_client_get_clients. Command context was not
2096 duplicated and was freed memory in the callback. Affected
2097 file lib/silcclient/idlist.c.
2099 * Do not say "you are now talking..." on JOIN command in the
2100 client library. The appliation must handle it.
2102 * Do not say ".. changed topic to" in command reply in the
2103 client libary. The application must handle it.
2105 * Fixed TOPIC command sending in the client library.
2107 * Fixed a memory leak in silc_client_command_free in the file
2108 lib/silcclient/command.c.
2110 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Imported a modified version of Irssi client to the source tree.
2113 The Irssi will be used to create a new client called
2114 Irssi SILC. Imported to irssi/.
2116 Added silc_core_init_finish function to the Irssi. Affected
2117 file irssi/configure.in.
2119 A lot changes in the Makefile.ams around the irssi tree.
2121 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2123 * Do not rehash if the new size is same as the old size of the
2124 hash table, in the silc_hash_table_rehash*. The affected file
2125 lib/silcutil/silchashtable.c.
2127 * Replaced hash_table_del_by_context calls from the server
2128 (when channel->user_list and client->channels) to the
2129 hash_table_del as it is sufficient and faster.
2131 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2133 * Added silc_hash_table_list, silc_hash_table_get and the
2134 SilcHashTableList structure to provide an alternative way to
2135 traverse the hash table. The affected files are
2136 lib/silcutil/silchashtable.[ch].
2138 * Changed the server's idlist routines to use the hash table
2139 routines to optimize the code.
2141 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Replaced the client entry's `channel' list and channel entry's
2144 `user_list' list to hash tables for optimized lookup. Changed
2145 the code to use the hash table interface around the code.
2146 Affected file lib/silcd/idlist.[ch].
2148 * Added `auto_rehash' boolean argument to the function
2149 silc_hash_table_alloc to indicate whether the hash table should
2150 auto-rehash when it thinks is appropriate time. It will
2151 increase the hash table size if the there is twice as much
2152 entries in the table than the size of the table, and will
2153 decrease the size if there are twice as less entries than
2154 the size of the table.
2156 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2160 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * silc_idcache_purge_by_context deletes the entry now by context
2163 as it is supposed to do. Affected file lib/silccore/idcache.c.
2165 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2166 client is not anymore valid (WHOWAS givens the info) and not
2167 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2169 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2171 * Removed the `data' and `data_len' arguments from the ID Cache
2172 interfaces and added `name' argument. ID Cache does not handle
2173 anymore the binary data only a names associated with given ID.
2175 * When hashing a Client ID with silc_hash_id the entire ID is
2176 not hashed anymore, instead only the hash of the Client ID is
2177 hashed. This way we can access the Client ID from the cache
2178 with Client ID but with the hash of the ID (which is a hash of
2179 the nickname) as well without any difference in performance.
2181 Added also silc_idcache_find_by_id_one_ext to do one on one
2182 searching when we have the actual ID. Added also function
2183 silc_hash_client_id_compare. The affected files are
2184 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2186 * When hashing the name associated with a ID it is always done
2187 in lowercase. This way we can access the cache without worrying
2188 about case-sensitivity, even though, for example nicknames are
2191 * Fixed a bug in server with channel message sending. It put
2192 wrong ID type as destination ID. The affected file
2193 silcd/packet_send.c.
2195 * silc_idcache_del_by_context now deletes from all hash tables
2196 by context. Affected file lib/silccore/idcache.c.
2198 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Changed the client library to use the new ID Cache interface.
2201 Changes around the source tree.
2203 * Added silc_hash_table_rehash_ext to rehash with specific
2204 hash function. Affected file lib/silcutil/silchashtable.[ch].
2206 * Added silc_hash_string_compare to compare two strings in the
2207 hash table. Affected file lib/silcutil/silcutil.[ch].
2209 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Added new function silc_idcache_del_by_context into the
2212 lib/silccore/idcache.[ch].
2214 * Changed the server's ID list routines to use the new ID Cache
2215 interface. Changes around the source tree.
2217 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * Added silc_hash_table_del[_by_context]_ext functions in to the
2220 lib/silcutil/silchashtable.[ch].
2222 Removed silc_hash_table_find_all* routines and added new
2223 silc_hash_table_find_foreach to replace them.
2225 Added silc_hash_table_replace_ext function as extended
2226 replacing function. Separated the simple hash table interface
2227 from the extended hash table interface in the file
2228 lib/silcutil/silchashtable.h.
2230 * Fixed minor bugs and changed it to use some of the new
2231 hash table functions in lib/silccore/idcache.c
2233 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Added new function silc_hash_table_find_all to return all keys
2236 in the hash table by the specified key. As the hash table is
2237 collision resistant it also makes it possible to have several
2238 duplicate keys in the hash table. This function may be used to
2239 find all of the keys from the hash.
2241 Added user_context arguments to the SilcHashFunction,
2242 SilcHashCompare and SilcHashDestructor to deliver user specified
2245 Added new fuctions silc_hash_table_find[_all]_ext to do
2246 extended lookup with specified hash and compare functions and
2247 specified user contexts.
2249 Added new function silc_hash_table_add_ext to add the key
2250 with specified hash function and user context.
2252 Added new function silc_hash_table_foreach to traverse all
2253 entrys in the hash table. Added SilcHashForeach callback
2256 Added new function silc_hash_table_del_by_context to delete
2257 the entry only if the context associated with the key matches.
2259 Affected files are lib/silcutil/silchashtable.[ch].
2261 * Removed silc_hash_[server/client/channel]_id and added just
2262 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2263 silc_hash_id_compare to compare two ID's using as the hash table
2264 comparison function. Added also silc_hash_data to hash
2265 binary data and silc_hash_data_compare to compare it.
2267 * Removed silc_idlist_find_client_by_hash as it is not needed
2268 anymore. Affected file silcd/idlist.[ch].
2270 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2271 to use internally the SilcHashTable. The new ID Cache is a lot
2272 faster than the old one. Some of the ID Cache interface was also
2273 rewritten and obsolete and stupid functions were removed.
2275 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Added entry_count field to the SilcHashTable to keep the number
2278 of the entries in the table. Implemented the function
2279 silc_hash_table_rehash. Added new function
2280 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2282 Fixed a minor bug in silc_hash_table_free.
2284 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2285 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2286 into the lib/silcutil/silcutil.[ch].
2288 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Implemented a collision resistant hash table into the
2291 lib/silcutil/silchashtable[ch]. See the header and the source
2292 for the SilcHashTable API.
2294 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Merged dotconf version 1.0.2 into lib/dotconf.
2298 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Do not compile anything in lib/silcsim/* if the SIM support
2301 is not enabled. The tree should now compile without problems
2304 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2306 * Compiled the SILC under cygwin. Compiled and tested briefly
2307 without problems. More tests needed. The SIMs didn't compile
2310 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2312 * Fixed possible crash in silc_get_username in the
2313 lib/silcutil/silcutil.c.
2315 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2317 * Fixed a va_arg in silc/client_ops.c.
2319 * Oops, RC5 routines were named AES and caused some problems
2320 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2322 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2324 * Added new SilcIDIP structure into the lib/silccore/id.h and
2325 replaced the old `ip' fields from all SILC ID's to that type.
2326 This is a step towards IPv6 support.
2328 The silc_id_get_len takes now the ID as an extra argument.
2329 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2330 both IPv4 and IPv6 based ID's.
2332 The affected files are lib/silccore/id.[ch] and other files
2333 around the tree using these routines.
2335 * Removed the ID length arguments in server from various
2336 silc_server_send_notify_* routines -> they are not needed
2339 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Fixed memory leak in silc_encode_pem_file in the file
2342 lib/silcutil/silcutil.c.
2344 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2346 * Check minor version as well in the SKE. Affected files are
2347 silcd/protocol.c and lib/silcclient/protocol.c.
2349 * Added --identifier option to the server so that an identifier
2350 can be when creating the public key for the server. Affected
2351 file is silcd/silcd.c.
2353 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2354 lib/silccrypt/silcpkcs.c.
2356 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Register default ciphers and stuff when using -C option with
2359 the server. Affected file sildc/silcd.c.
2361 * Put back the servers public key filename format, it is better
2362 than the new one. For now, the client keys are saved with the
2363 new filename format. The affected file silc/client_ops.c.
2365 * Implemented the Cipher API for the rest of the ciphers that
2366 did not implement it or implemented it the wrong way.
2368 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Register default ciphers and stuff when using the -S option
2371 in the client. Affected file silc/silc.c. Same also when
2372 creating new key pair with -C option.
2374 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Fixed the silc_verify_public_key client operation function to
2377 save the public keys differently. The fingerprint is now
2378 used as filename and not the hostname. This way also the
2379 client keys are saved uniquely and not with hostnames. The
2380 affected file is silc/client_ops.c.
2382 * Trimmed the silc_hash_fingerprint function to remove extra
2383 whitespaces from the end of the fingerprint. The affected
2384 file is lib/silccrypt/silchash.c.
2388 * Added silc_cipher_register_default function to register all
2389 default ciphers. It can be used when configuration files
2390 does not exist and the application does not want any specific
2391 ciphers in any specific order.
2393 The SilcDList is now used as silc_cipher_list dynamically
2394 allocated cipher list. Removed the static list all together
2395 and now all ciphers must be allocated to the dynamic list.
2396 The silc_cipher_alloc routine was changed to check only the
2399 All silc_cipher_* routines that used to return int returns
2402 The affected files lib/silccrypt/silccrypt.[ch].
2404 * The same thing was done to silc_hash_* as for silc_cipher_*
2405 routines. Affected files lib/silccrypt/silchash.[ch].
2407 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2408 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2409 Added also silc_pkcs_[un]register[_default] functions.
2410 Removed the data_context from the PKCS API.
2412 * Added silc_hmac_register_default function to register default
2413 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2414 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2415 to unregister all hmacs at once.
2417 * Register the default ciphers, hash functions, PKCSs and HMACs
2418 if client's configuration file does not exist. The affected
2421 * The client did not load the hash functions from the SIM
2422 modules at all. Added support for this. Affected file is
2423 silc/clientconfig.c.
2425 * When decoding public key with silc_pkcs_public_key_decode, check
2426 the supported algorithm only if PKCS are registered. Affected
2427 file lib/silccrypt/silcpkcs.c. The same was done with the
2428 silc_pkcs_private_key_decode.
2430 * Fixed the SILC List routines to keep the list always in order.
2431 It used to change the list's order when traversing the list but
2432 not it preserves the order. Affected file lib/trq/silclist.h.
2434 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Added the client library to use the SilcSocketConnection's
2437 reference counter (by silc_socket_dup) to prevent the bug that
2438 the socket object may be freed underneath async operation.
2440 * The name resolv library checking fixes in the configure.in.pre.
2443 * Created new version of the protocol drafts for future
2444 development. The -03 drafts are the ones that will be changed
2445 in the trunk now and the -02 will remain as they are.
2447 * Send list of CUMODE notifys to the router when announcing
2448 the channel users to the router. Affected file silcd/server.c.
2449 If the router receiving channel founder CUMODE for a channel
2450 that already has channel founder it will send CUMODE notify
2451 to the sender to remove the channel founder rights from the
2452 announced client. Affected file silcd/packet_receive.c.
2454 * The CUMODE notify may now use Server ID as well as the entity
2455 who changes the mode. Updated protocool specs.
2457 * Updated INSTALL and README files.
2459 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * New web pages in the http://silc.pspt.fi. The pages was
2466 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2468 * Implemented the [DenyConnectin] config section in the server.
2469 Added silc_server_config_denied_conn to check whether incoming
2470 connection is denied. Affected file silcd/serverconfig.[ch].
2472 * Do not check the ports when checking the incoming configuration
2473 data if the port is 0, meaning any. Affected file is
2474 silcd/serverconfig.c.
2476 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Fixed buffer overflow in silc_string_compare in the file
2479 lib/silcutil/silcutil.c.
2481 * Fixed double free in silc_server_command_leave in the file
2484 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2486 * Fixed the version checking in the server. Affected file is
2489 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Fixed the configuration data fetching when accepting new
2492 connections in the server. Affected file silcd/server.c.
2494 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Added `sender_entry' argument to the function
2497 silc_server_packet_relay_to_channel so that we can check
2498 whether some destination actually belongs to the same route
2499 the sender belongs (ie, we must not resend the packet to the
2500 sender). Affected file silcd/packet_send.[ch].
2502 * Added `servername' field to the SilcClientEntry in the server
2503 to hold the name of the server where client is from. Affected
2504 file is silcd/idlist.h.
2506 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Moved the channel message encrypting in the router betwen
2509 router connections from silc_server_channel_message to the
2510 silc_server_packet_relay_to_channel since we want to check
2511 whether we have anybody channel before encrypting anything.
2512 Affected files silcd/packet_[receive/send].c.
2514 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Fixed the [AdminConnection] server config section to support
2517 multiple entries. Affected file silcd/serverconfig.c.
2519 * Added support into the server to check the validity of the
2520 incoming connection before executing any KE or authentication
2523 * The connection configuration is now saved to the KE and
2524 connection auth protocol contexts and not fetched anymore in
2525 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2527 * The local hosts listenning address and port is also resolved
2528 now when starting the server. We want to have the socket object
2529 to include the real address and port for the listener. Added
2530 new function silc_net_check_local_by_sock into the files
2531 lib/silcutil/silcnet.[ch].
2533 * Fixed a broadcast bug in server -> do not broadcast if we
2536 * Fixed a routing bug. Do not route broadcast packets ever.
2537 Broadcast packets must be processed always and not routed since
2538 they may be destined to some other host than yourself and thus
2539 would get routed without no good reason. Affected file is
2542 * Added function silc_server_config_is_primary_route to check
2543 whether primary router connection has been configured (a router
2544 configuration that we are initiating). If there is not, we
2545 will assume that there is only two routers in the SILC network
2546 and we will use the incoming router connection as our primary
2547 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2549 * Changed the order of the broadcasting. Broadcast _after_ the
2550 packet has been processed not before. Affected file is
2553 * Fixed a [ClientConnection] parsing bug. The port was never
2554 parsed correctly thus resulting to port 0. Affected file
2555 silcd/serverconfig.c.
2557 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2558 argument and did not set the broadcast packet flag. Affected
2559 file silcd/packet_send.c. Fixed same bug in the function
2560 silc_server_send_notify as well.
2562 * If we receive NEW_ID packet for our own ID in the server, ignore
2565 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Removed the nickname from the Private Message Payload.
2570 Updated the code and the protocol specs.
2572 * Updated protocol specs for submitting to the IETF.
2574 * Tweaked the Random Number Generator a bit. Affected file
2575 lib/silccrypt/silcrng.c. Exported a new function
2576 silc_rng_[global]_add_noise which can be used to add more
2579 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2581 * Do not parse packets with different timeout when protocol
2582 is active -> may cause problem with rekey. Affected file
2585 * When server receives signoff notify it must not create
2586 new channel key if the client is on any channels since the
2587 sender of the signoff notify will create it.
2589 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Added printing of error messages during SKE protocol from the
2592 failure packet sent by server during SKE. Affected file
2595 * Removed the client's failure_callback handling with timeout
2596 and handle it immediately when received.
2598 * The SKE library returned wrong type in SUCCESS and FAILURE
2599 packets. They must be 32 bit MSB not 16 bit MSB.
2601 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2603 * Ok, rewrote the logic of the re-key and now it seems to work.
2604 I tested it on high traffic with frequent re-keys without
2605 problems. Added hmac_receive (and renamed hmac to hmac_send)
2606 in SilcClientConnection in lib/silcclient/client.h and
2607 in SilcIDListData in silcd/idlist.h. Also, removed the
2608 SilcPacketParserContext's cipher and hmac fields as they are
2609 not needed anymore and actually caused some problems when
2610 the ciphers and hmac's changed underneath the packet parser.
2612 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * If re-key protocol is active then process the incoming packets
2615 synchronously since we must assure that icoming packets encrypted
2616 with the old key is processed before the new keys is set to
2617 use. This is true other packets than for REKEY packets.
2618 Affected file silcd/server.c. The same was done to client library
2619 as well, affected file lib/silcclient/client.c.
2621 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Fixed bug in client and server to accept the force send if
2624 the packet is send from silc_[server/client]_packet_process
2625 function. Otherwise the packets are never delivered, oops.
2627 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Disable force sending of packets when REKEY protocol is active.
2630 We must assure that no packet is sent directly when rekey is
2631 performed. All packets must be sent through packet queue.
2632 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2633 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2634 function is silc_[server/client]_packet_send_real to check
2637 * Replaced the SIM paths from example config files to
2638 /usr/local/modules. Also, make install creates now
2639 /usr/local/silc/logs directory to hold all the SILC server
2642 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Made the configure.in.pre work on Solaris. Patch by salo.
2646 * Made all ciphers compatible with non-x86 machines. Defined
2647 CBC mode macros into lib/silccrypt/ciphers_def.h.
2649 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Fixed the make install.
2653 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2655 * When MAC computation fails the silc_packet_decrypt returned 0
2656 even though it was supposed to return -1. Fixed this. The
2657 affected file is lib/silccore/silcpacket.c.
2659 * Do not replace the config files in /etc/silc (in make install)
2660 if they already exist. Affected file ./Makefile.am.
2662 * Do not send re-key packets immediately but through packet queue.
2663 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2665 * Changed silc_net_check_host_by_sock to return FALSE if the
2666 IP/DNS could not be resolved. Though, it returns the IP address
2667 now even if it could not resolve it (but returns also FALSE).
2668 Affected file lib/silcutil/silcnet.[ch].
2670 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2672 * Added silc_pkcs_decode_identifier to decode the public key's
2673 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2674 Added also silc_pkcs_free_identifier. Added also new context
2675 SilcPublicKeyIdentifier.
2677 * Added -S option to the silc client. It is used to dump the
2678 contents of the specified public key file.
2680 * Changed the PKCS api to return the public key length when
2681 setting the public key.
2683 * Fixed a fatal bug in the public and private key file loading.
2684 Affected file lib/silccrypt/silcpkcs.c.
2686 * Execute the packet parsing for client with zero (0) timeout
2687 if the protocol is active. Affected file silcd/server.c.
2689 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2691 * Made the key generation options to the silcd program. Added
2692 -C option, equivalent to client's option.
2694 * Added new [ServerKeys] config section to the server. It
2695 configures the server's public and private key.
2697 * Defined generic Public Key Payload into the protocol
2698 specification to send specific type of public keys and
2701 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2702 public key or certificate.
2704 * Implemented the GETKEY command to the server and to the
2705 client library and on user interface.
2707 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2709 * Made preliminary `make install' work.
2711 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2713 * Added SilcServerRekey context into silcd/idlist.h.
2715 * Added the PFS support as defined in the specification to the
2716 SKE protocol. Affected files lib/silcske/*.c.
2718 * Added `ske_group' field to the SilcServerRekey context to hold
2719 the number of the SKE group that is used with PFS in re-key.
2720 Affected file silcd/idlist.h.
2722 * Added PFS re-key support to the server. Affected file is
2725 * Added silc_protocol_cancel to cancel execution of the next
2726 state of the protocol. Affected file is
2727 lib/silccore/silcprotocol.[ch].
2729 * Added the re-key support with and without PFS to the client
2730 library. Re-key is performed once in an hour, by default.
2732 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2733 Added silc_client_rekey_callback and silc_client_rekey_final.
2734 Affected files are lib/silcclient/protocol.[ch] and
2735 lib/silcclient/client.[ch].
2737 * Removed the `hmac_key' and `hmac_key_len' fields from the
2738 SilcClientConnection structure; not needed. Affected file is
2739 lib/silcclient/client.h.
2743 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Do not ask whether user wants to use the negotiated private key
2746 for private messages, just use it. Affected file is
2747 silc/local_command.c.
2749 * Added `send_enc_key' and `enc_key_len' fields to the
2750 SilcIDListData structure since they are needed in the re-key
2751 phase. Affected file is silcd/idlist.[ch].
2753 * Implemented the simple re-key protocol into the server.
2754 Affected files silcd/server.c and silcd/protocol.[ch]. The
2755 re-key will be performed once in an hour, by default.
2757 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2758 Added silc_server_rekey, silc_server_rekey_callback and
2759 silc_server_rekey_final.
2761 * Removed Tunneled flag from the protocol. Updated the code
2762 and the specifications.
2764 * Adde `pfs' field to the SilcIDListData to indicate whether
2765 the PFS is to be performed in the re-key. Affected file is
2768 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2770 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2771 int64 of at least the xintXX size. If void * is less that 4
2772 bytes uint32 * will be used. Defined bool as boolean.
2774 * Changed _ALL_ unsigned long and unsigned int to uint32,
2775 unsgined short to uint16 in the source tree.
2777 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2778 not handle clients that has entry->data.registered == FALSE.
2779 They are not in the network anymore. Affected file is
2782 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Implemented the sending of the SERVER_SIGNOFF notify in the
2785 server. Affected file is silcd/server.c.
2787 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2788 Added also silc_notify_payload_encode_args into the
2789 lib/silccore/silcnotify.[ch].
2791 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2792 Affected file silcd/packet_receive.c.
2794 * Implemented the SERVER_SIGNOFF notify handling in the client
2795 library. Affected file lib/silcclient/client_notify.c. Also,
2796 implemnted the printing of the SERVER_SIGNOFF info to the
2797 application. Affected file silc/client_ops.c.
2799 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2800 if the deleting was successful. Affected file silcd/idlist.[ch].
2802 * Added support for public key authentication in the connection
2803 authentication protocol in the client library. Affected file
2804 lib/silcclient/protocol.c.
2806 * Changed the server's silc_idlist_get_clients_by_* interface
2807 to support already allocated array so that new entries may be
2808 added to pre-allocated array. Affected file silcd/idlist.[ch].
2809 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2810 and command replies.
2812 * All command reply functions in the server now calls the
2813 pending command callback even if error occured. This way the
2814 error will be delivered to the client as well. Affected files
2815 silcd/command.c and silcd/command_reply.c.
2817 * Fixed INFO command to return local server's info if no server
2818 was provided. Affected file lib/silcclient/command.c.
2820 * Removed RESTART command for good. Updated the code and the
2823 * Rewrote parts of the task system. It is a bit simpler now.
2824 Removed unsued task priorities. The affected files are
2825 lib/silcutil/silctask.[ch].
2827 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Moved the USERS printing from the library to the application.
2830 Affected files lib/silcclient/command.c and silc/client_ops.c.
2832 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2836 * Added channel key re-key support. The re-key is perfomed
2837 only by the router and is done once in an hour. Added `rekey'
2838 field to the SilcChannelEntry in the server. Affected files
2839 silcd/server.c and silcd/idlist.h.
2841 * Added silc_task_unregister_by_context into the file
2842 lib/silcutil/silctask.[ch].
2844 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2846 * Added SILC_UMODE_GONE mode to indicate when the client is not
2847 present in the SILC network. Added also support to the local
2848 command AWAY that will set this mode. Added support of showing
2849 "xxx is gone" in WHOIS command. The USERS command shows the
2850 gone status as well.
2852 * Fixed setting server and router operator privileges in the
2853 server's UMODE command. Affected file silcd/command.c.
2855 * Merged the SKE KE1 and KE2 payloads into one payload. The
2856 new KE payload is equivalent to the old KE2 payload.
2858 Cleaned up the SKE Start Payload parsing. It now uses the
2859 simple buffer unformatting to do the parsing. A lot faster
2862 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2863 to the SKE that is used to indicate whether both of the SKE
2864 parties should perform authentication. By default only the
2865 responder performs authentication. By setting this flag also
2866 the initiator must do authentication. By default it is unset
2867 since in normal SKE case, client to server connection, only
2868 the responder should do authentication. When doing SKE between
2869 two clients both should perform authentication. Updated the
2870 code and the protocol specs.
2872 * A little fix to IDENTIFY command in the server. Search the
2873 client first by hash not nickname. Affected file is
2876 * Fixed the silc_client_close_connection to support closing
2877 the client to client connections wihtout deleting too much
2878 data. Affected file lib/silcclient/client.c.
2880 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2881 are received if protocol used to be active but is not anymore
2882 the application would crash due to NULL pointer dereference.
2883 Affected files silcd/server.c and lib/silcclient/client.c.
2885 * Added `hash' field to the SilcClientConnection to include
2886 the hash function negotiated in the SKE protocol.
2888 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2889 to set the channel founder authentication data. A client can
2890 claim the founder rights later by providing the authentication
2891 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2892 This way the channel founder can regain the channel founder
2893 privileges even it is left the channel. This works only on
2894 local server and the client must be connected to the same
2895 server to be able to regain the founder rights. Updated the
2896 protocol specs accordingly.
2898 Added support to the CMODE command in the client to set the
2899 founder auth data. Read the README to see how to set it.
2901 Added support to the CUMODE command to claim the founder
2902 rights. Read the README to see how to do it.
2904 Added support for the founder authentication to the Channel
2905 Entry in the server. Affected file silcd/idlist.h.
2907 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2908 server's CMODE command. Affected file silcd/command.c.
2910 * Added the following new functions into lib/silccore/silcauth.[ch]:
2911 silc_auth_get_method and silc_auth_get_data.
2913 * The server now saves the remote hosts public key to the
2914 SilcIDListData pointer. Affected file silcd/protocol.c.
2916 * The normal server now does not remove the channel entry from
2917 the cache if the founder authentication data is set. It used
2918 to remove it if the founder was the last one on the channel on
2919 the server and left the channel. The auth data is saved and
2920 if the channel is re-joined later the old entry is used with
2921 the old auth data. Affected files silcd/command_reply.c and
2924 * Removed the `pkcs' field from the SilcIDListData structure
2925 in the server; it is not used. Affected file silcd/idlist.h.
2927 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Fixed packet processing on slow links. Partial packets were
2930 never re-processed because the incoming data buffer was cleared
2931 by the application. Application must not directly clear the
2932 sock->inbuf, the packet processing routines handle it. Fixed
2933 this in client library and in server.
2935 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2937 * Fixed the WHOIS and IDENTIFY send reply function to really
2938 check whether to send list or just one entry. Affected file
2941 * Cleaned up the LEAVE command's channel key distribution. The
2942 affected file silcd/command.c.
2944 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2945 can enforce the channel mode as well. In that case the ID
2946 includes the ID of the server. The code now enforces the
2947 mode change if the router have different mode than the server.
2949 * The notify client operation with CMODE_CHANGE notify can now
2950 return NULL client_entry pointer if the CMODE was not changed
2951 by client. Application must check for this.
2953 * Added <Server ID> argument to INFO command to support server
2954 info fetching by Server ID.
2956 * Added silc_server_announce_get_channel_users to get assembled
2957 packets of channel users of the specified channel. Affected
2958 file silcd/server.[ch].
2960 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2961 was freed underneath the ID Cache.
2963 * Re-announce clients when the server received CHANNEL_CHANGE
2964 notify from the router. Affected file silcd/packet_send.c.
2966 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2969 crashed since it did not handle the fact that there is no cipher
2970 called "3" and didn't check the error condition. Now fixed.
2972 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2973 flag. It can be used to send message requests.
2975 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2977 * Implemented the RESTART command in the client.
2979 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2980 notice type messages. Added notice printing to the user
2983 * The channel keys are not re-generated if the channel's mode
2984 is PRIVKEY, ie private key on the channel exists. Affected
2985 files silcd/server.c and silcd/command.c.
2987 * Fixed a little bug in channel message delivery when channel
2988 private keys are set in the server. Affected file is
2989 silcd/packet_send.c.
2991 * Changed the setting on channel->on_channel = TRUE from the
2992 silc_client_save_channel_key to the JOIN command reply. The
2993 key payload is not received if the private channel key is set.
2994 Affected file lib/silcclient/command_reply.c and the
2995 lib/silcclient/client_channel.c.
2997 * When the CMODE_CHANGE notify is sent and the channel private
2998 key mode is removed the channel key must be re-generated in
2999 other cells as well. Added this support for the router in the
3000 silcd/packet_receive.c.
3002 * Added new local command NOTICE to send notice message on
3003 channel. Affected file silc/local_command.[ch].
3005 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Added new local command ME to the client. It is used to send
3008 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3009 some action. Affected file silc/local_command.[ch].
3011 * Changed channel_message and private_message client operations
3012 to deliver the message flags to the application. Added also
3013 the `flags' arguments to the silc_client_send_channel_message
3014 and silc_client_send_private_message functions. Affected file
3017 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Redefined the Private Message Payload to support private message
3020 keys and to support the new private message flags. Updated
3021 the protocol specs. Flags makes it possible to have for example
3022 CTCP style messages.
3024 * Added new type SilcPrivateMessagePayload and defined an API
3025 for it in the lib/silcclient/silcprivate.[ch].
3027 * Tested private message private keys successfully. Tested the
3028 private message key set, unset and list commands with the new
3031 * Redefined the Channel Message Payload to include the channel
3032 message flags (equal with private message flags) to support
3033 for example CTCP style messages.
3035 * Defined some of the message (for channel and private message)
3036 flags. Updated the protocol specs and added the flags to the
3037 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3039 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3041 * Added SilcKeyAgreementStatus type to the key agreement routines
3042 to indicate the current status and error if one occured.
3043 The status types are defined in the lib/silcclient/silcapi.h.
3045 * Added new local command KEY that is used to set and unset private
3046 keys for channels, set and unset private keys for private messages
3047 with remote clients and to send key agreement requests and
3048 negotiate the key agreement protocol with remote client. The
3049 key agreement is supported only to negotiate private message keys,
3050 it currently cannot be used to negotiate private keys for channels,
3051 as it is not convenient for that purpose.
3053 * Fixed a minor pending callback setting bug in the function
3054 silc_client_get_client_by_id_resolve, now the function works.
3055 Affected file lib/silcclient/idlist.c.
3057 * Added function silc_net_get_local_port to get local bound
3058 port by socket. Added to lib/silcutil/silcnet.[ch].
3060 * Added `sockets' and `sockets_count' fields to the SilcClient
3061 object. They hold the sockets of the listenning sockets in
3062 the client. Listenning sockets may be for example the key
3063 agreement server. Affected file lib/silcclient/client.[ch].
3064 Added functions the silc_client_add_socket and the
3065 silc_client_del_socket. They are exported to the application
3068 * Added ~./silc/clientkeys to support other client's public keys.
3070 * Renamed verify_server_key client operation to verify_public_key
3071 and added one argument to indicate the type of the connection
3072 (server, client etc.).
3074 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Added silc_server_connection_auth_request to handle the
3077 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3078 silcd/packet_receive.[ch].
3080 * Added silc_server_send_connection_auth_request into the
3081 silcd/packet_send.c to send the connection auth request packet.
3083 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3086 * Fixed the public key authentication in responder side in the
3087 server. The `auth_data' pointer includes the SilcPublicKey
3088 not the path to the public key. Affected file silcd/protocol.c.
3090 * Implemented the public key authentication in the initiator side
3091 in the server. Affected file silcd/protocol.c.
3093 * Removed the [RedirectClient] config section from the server
3094 configuration. Is not needed and I don't want to implement it.
3096 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Cleaned up the CMODE command in the server. It now works
3099 correctly and supports all the modes defined in the protocol.
3100 Affected file is silcd/command.c.
3102 * Added `hmac_name' field to the SilcChannelEntry in the server
3103 to hold the default HMAC of the channel. It can be set when
3104 creating the channel (with JOIN command). Affected files
3107 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3108 type to indicate the change of the current cipher and hmac
3109 on the channel. Client can safely ignore the <cipher> argument
3110 (if it chooses to do so) since the CHANNEL_KEY packet will
3111 force the channel key change anyway. The <hmac> argument is
3112 important since the client is responsible of setting the new
3113 HMAC and the hmac key into use.
3115 * Fixed the CMODE command in the client library as well.
3117 * Tested CMODE command in router environment successfully.
3119 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3121 * Show the version of the remote client (or server) when connecting
3122 to the server. It is logged to the log file. Affected file
3123 is silcd/protocol.c.
3125 * Fixed the KILLED notify handling in the client library. The
3126 client must be removed from all channels when receiving the
3129 Also, do not remove the client entry when giving the KILL
3130 command but when the KILLED notify is received.
3132 * Removed silc_idlist_find_client_by_nickname from the server.
3133 Not needed anymore. Affected files silcd/idlist.[ch].
3135 * Implemented the CHANNEL_CHANGE notify type handling to the
3136 server. Affected file silcd/server.c.
3140 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * Added silc_server_send_notify_invite to send the INVITE
3143 notify between routers.
3145 * Implemented the INVITE command correctly to the server.
3147 * Implemented the INVITE notify type handling in the server.
3149 * Implemented the INVITE command to the client library and on the
3152 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Added function silc_server_get_client_resolve to find the
3155 client entry by ID from all ID lists and then resolve it
3156 (using WHOIS) if it cannot be found. Affected file is
3159 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Implemented the BAN command to the client library.
3163 * The JOIN command in the server now checks the invite list
3166 * Changed the silc_command_reply_payload_encode_va and the
3167 silc_command_payload_encode_va to support that if argument is
3168 NULL it ignores and checks the next argument. Affected file
3169 lib/silccore/silccommand.c.
3171 * Added silc_server_send_notify_ban to send the BAN notify
3172 type between routers.
3174 * Chaned the silc_notify_payload_encode to support that if
3175 argument is NULL it ignores and checks the next argument.
3176 Affected file lib/silccore/silcnotify.c.
3178 * Tested ban lists in router environment successfully.
3180 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3182 * Implemented BAN command to the server, in silcd/command.[ch].
3184 * Removed the BAN and INVITE_LIST modes from the CMODE command
3187 * Added function silc_string_match to regex match two strings.
3188 Affected files lib/silcutil/silcutil.[ch].
3190 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3192 * Redefined parts of the SilcChannelEntry in the server to support
3193 the new ban and invite lists.
3195 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Redefined the INVITE command. The same command can be used to
3198 invite individuals to the channel but also to manage the invite
3199 list of the channel (to add to and remove from the invite list).
3200 Updated the protocol specs.
3202 * Added new command SILC_COMMAND_BAN that can be used to manage
3203 the ban list of the channel. Updated the protocol specs.
3205 * Removed the channel modes: the SILC_CMODE_BAN and the
3206 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3207 in the CMODE command. The equivalent features are now available
3208 using INVITE and BAN commands. Updated the protocol specs.
3210 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3211 in the network about change in the current ban list. The notify
3212 type is not used by the client.
3214 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3215 support the invite lists.
3217 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Added new function silc_string_regexify that converts string
3220 including wildcard characters into regex string that can
3221 be used by the GNU regex library. Added into the file
3222 lib/silcutil/silcutil.[ch].
3224 Added silc_string_regex_combine to combine to regex strings
3225 into one so that they can be used as one regex string by
3226 the GNU regex library. Added into the file
3227 lib/silcutil/silcutil.[ch].
3229 Added silc_string_regex_match to match two strings. It returns
3230 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3232 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3234 * Imported GNU regex to the soruce tree into lib/contrib.
3235 Fixed some compiler warning from the regex.c.
3237 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Fixed MOTD command in the server to work in router environment.
3241 * Fixed the MOTD command in the client library to support
3242 the server argument in the command.
3244 * Added `nickname_len' argument to the silc_idlist_add_client
3245 in the server, as the `nickname' argument may be binary data
3248 * Added silc_idlist_get_channels to return all channels from
3251 * Implemented LIST command to the server. Affected file is
3254 * Implemented the LIST command to the client library and on the
3257 * Added [<user count>] argument to the LIST command reply.
3258 With private channels the user count is not shown.
3260 * Updated TODO and README.
3262 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3264 * The client entry's data.registered must be TRUE even with
3265 global client entry on global client list. The data.registered
3266 is used to check whether the client is anymore in the network,
3267 for example with WHOWAS command so it must be valid.
3269 * Fixed the WHOWAS command in the server. It now actually works
3270 in router environment. Added function into silcd/command_reply.c
3271 silc_server_command_reply_whowas_save.
3273 * Added silc_idlist_purge function to the silcd/idlist.c
3274 to periodically purge the ID Cache.
3276 * Fixed INFO command in the server. It works now in router
3277 environment. Added <server name> argument to the INFO command
3278 reply. Updated the protocol specs.
3280 * Fixed minor bug in silc_idcache_purge to not purge if the
3281 expire value is zero.
3283 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3284 they were buggy because of the WHOWAS information.
3286 * Fixed local command MSG to handle the async resolving of
3287 the remote client properly. It used to fail the first MSG.
3288 Affected file silc/local_command.c.
3290 * Added `data_len' field to SilcIDCache context.
3292 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Update TODO. Todo in commands in the server.
3296 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3299 used by routers as broadcast packet to inform other routers
3300 about the changed user mode.
3302 Implemented the notify handling in the server. Affected file is
3303 silcd/packet_receive.c. Added the function
3304 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3306 * Added new generic Channel Payload and deprecated the New Channel
3307 Payload. The New Channel Payload is now the generic Channel
3310 * Added new argument `mode' to the silc_server_send_new_channel
3311 as it is required in the Channel Payload now.
3313 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3314 and created a new and real SilChannelPayload to represent the
3315 new generic Channel Payload. Implemented the encode/decode
3316 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3318 * Added silc_server_get_client_channel_list to return the list
3319 of channels the client has joined for WHOIS command reply.
3320 Affected file silcd/server.[ch].
3322 * Implemented the channel list sending in the WHOIS command reply
3323 in server and in the client.
3325 Implemented the channel list displaying on the user interface
3326 as well. Affected file silc/client_ops.c.
3328 * Added silc_channel_payload_parse_list to parse list of Channel
3329 Payloads. It returns SilcDList list of SilcChannelPayloads.
3330 Client for example can use this function to parse the list of
3331 channels it receives in the WHOIS command reply. The caller
3332 must free the list by calling silc_channel_payload_list_free.
3333 Affected files lib/silccore/silcchannel.[ch].
3335 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Added one new argument <user mode> to the WHOIS command reply
3338 to return the mode of the user in SILC. Updated the protocol
3341 Implemented it to the server and client.
3343 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3345 * Fixed the mode printing on the user interface on joining.
3346 Affected file silc/client_ops.c.
3348 * Implemented the UMODE command and user modes in general to the
3349 client library and to the user interface.
3351 * Implemented the UMODE command to the server.
3353 * The server now sends UNKNOWN_COMMAND error status if client sends
3354 unknown command. Affected file silcd/command.c.
3356 * All server commands now handle the command identifier the right
3357 way when sending the command reply to the client. The client can
3358 use to identify the command replies with the identifier.
3360 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added silc_server_get_client_route to resolve the route to
3363 the client indicated by the client ID. Affected file is
3366 * Added silc_server_relay_packet as general function to relay
3367 packet to arbitrary destination. This deprecates functions
3368 like _send_private_message_key, _relay_notify etc. Affected
3369 file is silcd/packet_send.[ch].
3371 Removed silc_server_send_key_agreement,
3372 silc_server_send_private_message_key and
3373 silc_server_packet_relay_notify functions from the file
3374 silcd/packet_send.[ch].
3378 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3379 server. Affected file silcd/packet_receive.[ch].
3381 * Implemented the KILL command to the client. Implemented the
3382 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3383 Affected files lib/silcclient/command[_reply].c and
3384 lib/silcclient/client_notify.c. Implemented the KILL notify
3385 printing in the user inteface.
3387 * Fixed a lot silc_parse_nick memory leaks from the client
3388 library in the file lib/silcclient/command.c.
3390 * Changed the silc_server_send_notify_on_channels's `sender'
3391 argument from SilcSocketConnection to SilcClientEntry to
3392 check the sender as entry and not as connection object and not
3393 to send to the client provided as argument. The affected file
3394 is silcd/packet_send.[ch].
3396 * The notify packets that are destined directly to the client used
3397 to not to be processed by the server. Now changed that and the
3398 server processes all notify packets. After relaying the packet
3399 to the client the notify packet is processed in the server.
3401 * The silc_server_free_client_data now checks whether there is
3402 pending outgoing traffic for the client and purges the data to
3403 the network before removing the client entry.
3405 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3408 an client is killed from the SILC Network. Updated the protocol
3411 Added new function silc_server_send_notify_killed to the
3412 silcd/packet_send.[ch].
3414 * Added function silc_server_packet_relay_notify to relay notify
3415 packets that are destined directly to a client. In this case
3416 the server does not process the notify packets but merely relays
3417 it to the client. Affected file silcd/packet_send.[ch].
3419 Added also silc_server_packet_process_relay_notify to check
3420 whereto relay the notify. Affected file is
3421 silcd/packet_receive.[ch].
3423 * Implemented the KILL command to the server.
3427 * Added the backup schema desgined last fall to the protocol
3428 specs for everyone to see. The specification is in the
3429 *-spec-xx.txt draft and the packet type definitions for the
3430 backup routers is in *-pp-xx.txt draft. Thusly, added also
3431 new packet type SILC_PACKET_CELL_ROUTERS.
3433 * A big security problem in the implementation discovered. The
3434 signoff of an client did not cause new channel key generation
3435 which it of course should've done. The channel keys must be
3436 always re-generated when client leaves (or signoffs) the channel.
3437 The silc_server_remove_from_channels funtion now handles
3438 the channel key re-generation.
3440 * Added `sender' argument to the silc_server_send_notify_on_channels
3441 to not to send the client provided as argument. Affected file
3442 silcd/packet_send.[ch].
3444 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Implemented OPER and SILCOPER commands into the server and
3449 * Added silc_auth_verify and silc_auth_verify_data to verify
3450 the authentication directly from the authentication payload.
3451 It supports verifying both passphrase and public key based
3452 authentication. Affected file lib/silccore/silcauth.[ch].
3454 * Added `hash' field to the SilcIDListData structure. It is the
3455 hash negotiated in the SKE protocol. Affected file is
3458 * Slight redesigning of the SilcAuthPayload handling routines.
3459 Do not send SilcPKCS but SilcPublicKey as argument.
3461 * Implemented the public key authentication support to the
3462 serverconfig. The public key is loaded from the provided path
3463 and saved as authentication data to void * pointer. Thus,
3464 changed the unsigned char *auth_data to void *auth_data;
3466 * Fixed SHUTDOWN command to send the reply before the server
3467 is shutdown. :) Affected file silcd/command.c.
3469 * Fixed fatal bug in CONNECT command. The hostname was invalid
3470 memory and server crashed. Affected file silcd/command.c.
3472 * Fixed fatal bug in CLOSE command. The server_entry became
3473 invalid but was referenced later in the command. Affected file
3476 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3478 * Fixed fatal bug in failure packet handling. Server ignored
3479 the failure and thus crashed when it came.
3483 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3486 that the command may be executed only once in (about) 2 seconds.
3487 The old SILC_CF_LAG flag is same but allows command bursts up
3488 to five before limiting.
3490 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3491 server code. Various commands now includes the CF_LAG_STRICT
3492 flag to disallow any kind of miss-use of the command.
3494 * Fixed the silc_buffer_unformat to not to allocate any data
3495 if the length of the data is zero. It used to allocate the
3496 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3498 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Changed the format of AdminConnection configuration section
3501 in the server. Added username of the admin to the format.
3502 Affected files silcd/serverconfig.[ch].
3504 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3505 to return admin configuration data by host, username and/or
3508 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Implemented WHOWAS command to the server. Added the functions:
3512 silc_server_command_whowas_parse,
3513 silc_server_command_whowas_send_reply,
3514 silc_server_command_whowas_from_client and
3515 silc_server_command_whowas_from_server
3517 * Added <Client ID> argument to the WHOWAS command reply. Updated
3518 the protocol specs accordingly.
3520 * Implemented WHOWAS command and command_reply to the client
3523 Implemented the WHOWAS printing on the user interface.
3525 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3527 * Added new argument to the WHOWAS command reply, the real name.
3528 It is an optional argument. Updated the protocol specs.
3530 * Added SilcIDCacheDestructor callback that is registered when
3531 the SilcIDCache is allocated. The callback is called when
3532 an cache entry in the ID Cache expires, or is purged from the
3533 cache. Added into lib/silccore/idcache.[ch].
3535 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3536 to destruct the client entries when the cache entry expires.
3537 Other ID Cache's in server and in the client library ignores
3540 * If the ID Cache entry's `expire' field is zero then the entry
3541 never expires. Added boolean `expire' argument to the
3542 silc_idcache_add function in the lib/silccore/idcache.[ch].
3543 If it is TRUE the default expiry value is used.
3545 * Added silc_server_free_client_data_timeout that is registered
3546 when client disconnects. By default for 5 minutes we preserve
3547 the client entry for history - for WHOWAS command.
3549 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3551 * Added support to the server to enforce that commands are not
3552 executed more than once in 2 seconds. If server receives
3553 commands from client more frequently, timeout is registered
3554 to process the commands. Affected file silcd/command.c.
3555 Added new function silc_server_command_process_timeout.
3557 * Changed NICK_NOTIFY handling in client library to check that
3558 if the client's nickname was changed, so there is no need to
3559 resolve anything from the server.
3561 * Removed error printing from the WHOIS and IDENTIFY commands.
3562 If error occurs then it is ignored silently in the client library.
3563 The application, however, may map the received error to
3564 human readable error string. The application currently maps
3565 the NO_SUCH_NICKNAME error to string.
3567 * Made the command status message public to the application. Moved
3568 them from lib/silcclient/command_reply.c to
3569 lib/silcclient/command_reply.h. The application can map the
3570 received command status to the string with the
3571 silc_client_command_status_message function.
3573 * Added check to the server to check that client's ID is same
3574 as the Source ID in the packet the client sent. They must
3577 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Added dist-bzip hook to the Makefile.am to make bzip2
3580 compressed distributions.
3582 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Server now enforces the maximum length for the nickname and
3585 the channel as protocol specification dictates. 128 bytes for
3586 nickname and 256 bytes for channel name.
3588 * Moved the WHOIS printing to the application. The client libary
3589 does not print out the WHOIS information anymore, the application
3590 must do it. Renamed silc_client_command_reply_whois_print to
3591 the silc_client_command_reply_whois_save.
3593 The client's idle time is also sent to the application now, and
3594 the idle is shown on screen.
3596 * Added silc_client_command_reply_identify_save to save the
3597 received IDENTIFY entries.
3599 * Do not check for channel private keys in message sending and
3600 reception if the channel does not have the PRIVKEY mode set.
3601 Affected file lib/silclient/client_channel.c.
3603 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3606 just surfaced after chaning the JOIN procedure.
3608 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * Added silc_client_get_clients_by_list to get client entries
3611 from Client ID list, that is returned for example by JOIN
3612 and USERS command replies. The application should use this
3613 function for example when JOIN command reply is received to
3614 resolve the clients already on the channel (library does not
3615 do that anymore as USERS command reply is not used in the JOIN
3616 procedure anymore). Affected files lib/silcclient/silcapi.h and
3617 lib/silcclient/idlist.c.
3619 * JOIN command reply and USERS command reply returns now SilcBuffer
3620 pointers instead of unsigned char pointers when returning
3621 the client list and mode list.
3623 * Added <Client ID> argument to the JOIN command reply, mainly
3624 for the server to identify for which client the command was
3625 originally sent. Updated protocol specs accordingly.
3627 * Added SilcDlist private_key pointer to the SilcChannelEntry
3628 in the client to support the channel private keys. Affected
3629 file is lib/silcclient/idlist.h.
3631 * Added SilcChannelPrivateKey argument to the function
3632 silc_client_send_channel_message so that application can choose
3633 to use specific private ke if it wants to. If it is not provided,
3634 the normal channel key is used, unless private keys are set.
3635 In this case the first (key that was added first) is used
3636 as the encryption key.
3638 * Implemented the support for channel private key handling.
3639 Implemented the following functions:
3641 silc_client_add_channel_private_key,
3642 silc_client_del_channel_private_keys,
3643 silc_client_del_channel_private_key,
3644 silc_client_list_channel_private_keys and
3645 silc_client_free_channel_private_keys
3647 Affected file lib/silcclient/client_channel.c.
3649 * Added the support for the private keys in the channel message
3650 sending and encryption and in the message reception and
3651 decryption. Affected funtions are
3652 silc_client_send_channel_message and silc_client_channel_message.
3654 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Added SKE's key verify callback to the client library's
3657 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3659 * Removed the statement that server (or router) must send USERS
3660 command reply when joining to the channel so that the client
3661 knows who are on the channel. Instead, the client list and
3662 client's mode list is now sent in the JOIN command reply to the
3663 client who joined channel. This is better solution.
3665 * Added function silc_server_get_users_on_channel and function
3666 silc_server_save_users_on_channel to the silcd/server.[ch].
3668 * Removed function silc_server_command_send_users from the
3671 * Do not show topic on the client library anymore. The topic is
3672 sent in the command reply notify to the application and the
3673 application must show the topic now.
3675 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3677 * Added client searching by nickname hash into the IDENTIFY and
3678 WHOIS commands in the server as they were clearly missing from
3679 them. Affected file is silcd/command.c.
3681 * Fixed a bug in private message receiving in the client library.
3682 The remote ID was freed and it wasn't supposed, now it is
3685 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Minor fix to the channel payload; allocate the data area, as it
3688 needs to be of specific length.
3690 * If the key agreement port is zero then the operating
3691 system will define the bound port. Affected files are
3692 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3694 * Added new function silc_channel_payload_decrypt into the file
3695 lib/silccore/silcchannel.[ch].
3697 * Moved the channel message etc, check from silc_packet_decrypt
3698 to applications. The library calls now a generic
3699 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3700 when the packet is either normal or special. This was done to
3701 allow more wide range of checking that was not allowed when
3702 the code was in library. Now applications can do virtually any
3703 checks to the packet and return to the library the decision how
3704 the packet should be processed. Affected files are
3705 lib/silccore/silcpacket.[ch].
3707 Added silc_server_packet_decrypt_check to the server and
3708 silc_client_packet_decrypt_check to the client library.
3710 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3711 to send with specified source and destination information.
3713 * Channel message delivery between routers was broken after the
3714 channel key distribution was fixed earlier. The channel key
3715 was used be to distributed to other routers as well which is not
3716 allowed by the protocol. Now this is fixed and channel keys
3717 really are cell specific and the channel message delivery between
3718 routers comply with the protocol specification.
3720 * Fixed various commands in server to check also the global list
3721 for the channel entry and not just the local list. The affected
3722 file silcd/command.c.
3724 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Added assert()s to buffer formatting and unformatting routines
3727 to assert (if --enable-debug) when error occurs. Affected
3728 file: lib/silcutil/silcbuffmt.c.
3730 * Changed to auto-reconnect to check whether the remote host is
3731 router and register the re-connect timeout if it is. It used
3732 to check that whether we are normal server, but router must do
3733 auto-reconnect with another router as well. Affected file
3736 * Removed the [<key len>] option from CMODE command as the cipher
3737 name decides the key length, nowadays. See the defined ciphers
3738 from the protocol specification.
3740 * Added [<hmac>] option to the CMODE command to define the HMAC
3741 for the channel. Added SILC_CMODE_HMAC channel mode.
3743 * Added [<hmac>] option for the JOIN command so that user can
3744 select which HMAC is used to compute the MACs of the channel
3747 * Added Hmac field to the Channel Message Payload. The integrity
3748 of plaintext channel messages are now protected by computing
3749 MAC of the message and attaching the MAC to the payload. The
3750 MAC is encrypted. Now, it is clear that this causes some
3751 overhead to the size of the packet but rationale for this is that
3752 now the receiver can verify whether the channel message decrypted
3753 correctly and also when private keys are set for the channel the
3754 receiver can decrypt the packet with several keys and check from
3755 the MAC which key decrypted the message correctly.
3757 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3758 lib/silccrypt/silccipher.[ch].
3760 * Added silc_hash_len to return the digest length into the
3761 lib/silcrypt/silchash.[ch].
3763 * Rewrote parts of Silc Channel Payload interface in the
3764 lib/silccore/silcchannel.[ch]. The encode function now also
3765 encrypts the packet and parse function decrypts it.
3767 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Fixed a minor formatting bug in the SKE's key material processing.
3770 It actually might have processed the keys wrong way resulting
3773 * Redefined the mandatory HMAC algorithms and added new algorithms.
3774 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3775 and hmac-md5 truncated to 96 bits. The mandatory is now
3776 hmac-sha1-96. Rest are optional (including the one that used
3777 to be mandatory). Rationale for this is that the truncated HMAC
3778 length is sufficient from security point of view and can actually
3779 make the attack against the HMAC harder. Also, the truncated
3780 HMAC causes less overhead to the packets. See the RFC2104 for
3783 * Added new [hmac] configuration section. The SKE used to use
3784 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3785 is of course wrong. The official names that must be proposed in
3786 the SKE are the ones defined in the protocol specification
3787 (hmac-sha1-96 for example). The user can configure any hmac
3788 using any hash function configured in the [hash] section. At
3789 least, the mandatory must be configured.
3791 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3793 * Added HMAC list to the SKE proposal list. It has now both
3794 hash algorithm list and HMAC list. This makes the protocol
3795 incompatible with previous versions. The SKE now seems to work
3796 the way it is supposed to work, for the first time actually.
3798 * Defined plain Hash algorithms to the protocol specification.
3801 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Implemented support for key agreement packets into the server.
3804 Added functions silc_server_key_agreement and
3805 silc_server_send_key_agreement. Other than these functions,
3806 server has nothing to do with this packet.
3808 * Added support for private message key packets into the server.
3809 Added functions silc_server_private_message_key and
3810 silc_server_send_private_message_key.
3814 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3815 called in the protocol's final callback instead in the END
3816 protocol state. This makes a little more sense and in the same
3817 time in client we can use the same protocol routines for normal
3818 key exchange and to key agreement packet handling as well.
3820 * Added to both client's and server's KE protocol context the
3821 SilcSKEKeyMaterial pointer to save the key material. We will
3822 bring the key material to the protocol's final callback by doing
3823 this. The final callback must free the key material.
3825 * Added SKE's packet_send callback into client's KE protocol
3826 context so that the caller can choose what packet sending function
3827 is used. This way we can use different packet sending when
3828 doing normal SKE when doing key agreement packet handling (in
3829 the key agreement packet handling we do not want to encrypt
3832 * Implemented the responder side of the key agreement routines
3833 in the client. The client can now bind to specified port and
3834 accept incoming key negotiation. The key material is passed
3835 to the application after the protocol is over.
3837 * Implemented the processing of incoming Key Agreement packet
3838 in the client. Added function silc_client_key_agreement to
3841 * Implemented the intiator side of the key agreement routines
3842 in the client. The client can now initiate key agreement with
3843 another remote client. The key material is passed to the
3844 application after the protocol is over.
3846 * Created client_keyagr.c to include all the key agreement
3849 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3850 SILC_TASK_CALLBACK except that it is not static.
3852 * Created client_notify.c and moved the Notify packet handling
3853 from the client.[ch] into that file.
3855 * Created client_prvmsg.c and moved all private message and
3856 private message key routines from the client.[ch] into that file.
3858 * Create client_channel.c and moved all channel message and
3859 channel private key routines from the client.[ch] into that file.
3861 * Changed silc_client_get_client_by_id_resolve to resolve with
3862 WHOIS command instead of IDENTIFY command, in the file
3863 lib/silclient/idlist.c.
3865 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Implemented the SKE's responder side to the Client library.
3869 * When FAILURE is received to the protocol do not trust it
3870 blindly. Register a timeout to wait whether the remote closes
3871 the connection as it should do it, only after that process the
3872 actual failure. This was changed to both client and server.
3874 * Added client_internal.h to include some of the structures
3875 there instead of client.h in lib/silcclient/.
3877 * Added function silc_task_unregister_by_callback to unregister
3878 timeouts by the callback function.
3880 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3882 * Some "Incomplete WHOIS info" errors has been appearing on the
3883 log files. Took away the entry->userinfo check from WHOIS
3884 reply sending. The entry->userinfo is now " " if client did not
3885 provide one. I thought this was fixed earlier but something
3886 is wrong still. Let's see if the error still appears.
3888 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Fixed a minor bug in the login when the channel key is
3891 re-generated in the server. It used to generate the key in
3892 wrong order and thus caused problems in the channel traffic.
3894 * Fixed a minor bug in channel key distsribution after
3895 KICK command. The key was not sent to the router even though
3898 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3900 * Added silc_ske_process_key_material_data as generic routine
3901 to process any key material as the SILC protocol dictates. The
3902 function is used by the actual SKE library but can be used by
3903 applications as well. This relates to the private message keys
3904 and the channel private keys since they must be processed the
3905 same way the normal SILC session keys. The protocol dictates
3906 this. Affected files: lib/silcske/silcske.[ch].
3908 Added also silc_ske_free_key_material to free the
3909 SilcSKEKeyMaterial structure.
3911 * Defined silc_cipher_set_key function to set the key for
3912 cipher without using the object's method function. The affected
3913 files: lib/silccrypt/silccipher.[ch].
3915 * Implemented silc silc_client_add_private_message_key,
3916 silc_client_add_private_message_key_ske,
3917 silc_client_del_private_message_key,
3918 silc_client_list_private_message_keys and
3919 silc_client_free_private_message_keys functions in the
3922 Added functions silc_client_send_private_message_key to send
3923 the Private Message Key payload and silc_client_private_message_key
3924 to handle incoming Private Message Key payload.
3926 * Added Cipher field to the Private Message Key payload to set
3927 the cipher to be used. If ignored, the default cipher defined
3928 in the SILC protocol (aes-256-cbc) is used.
3930 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Removed lib/silcclient/ops.h file.
3934 Redefined parts of the SILC Client Library API. Created new
3935 file silcapi.h that deprecates the ops.h file and defines the
3936 published Client Library API. Defined also private message key
3937 API and channel private key API into the file.
3939 This is the file that the application must include from the
3940 SILC Client Library. Other files need not be included by
3941 the application anymore.
3943 * Added new key_agreement client operation callback and also
3944 defined the Key Agreement library API for the application.
3946 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3949 is used by clients to request key negotiation between another
3950 client in the SILC network. If the negotiation is started it
3951 is performed using the SKE protocol. The result of the
3952 negotiation, the secret key material, can be used for example
3953 as private message key.
3955 Implemented the Key Agreement payload into the files
3956 lib/silccore/silauth.[ch].
3958 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Redefined ciphers for the SILC protocol. Added some new ciphers
3961 and defined the key lengths for the algorithms. Changed the
3962 code accordingly. The default key length is now 256 bits.
3964 * Fixed SKE key distribution function silc_ske_process_key_material
3965 when the key length is more than 128 bits. The default key
3966 length in SILC is now 256 bits.
3968 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3969 to indicate unsupported algorithm.
3971 * Renamed rijndael.c to aes.c and all functions as well.
3973 * Fixed a long standing channel key setting bug in client library.
3974 Weird that it has never surfaced before.
3976 * Fixed bug in channel deletion. If the entire channel is removed
3977 then it must also delete the references of the channel entry
3978 from the client's channel list as the client's channel entry and
3979 the channel's client entry share same memory.
3981 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Implemented CONNECT and SHUTDOWN commands in the client.
3985 * Implemented CLOSE command to the client.
3987 * Added the function silc_idlist_find_server_by_name into the
3988 files silcd/idlist.[ch].
3990 Added the function silc_idlist_find_server_by_conn into the
3991 files silcd/idlist.[ch].
3993 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3995 * DIE command was renamed to SHUTDOWN. Updated the both code
3998 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3999 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4001 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4004 * Added function silc_server_create_connection function to create
4005 connection to remote router. My server implementation actually
4006 does not allow router to connect to normal server (it expects
4007 that normal server always initiates the connection to the router)
4008 so the CONNECT command is only good for connecting to another
4011 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4014 or some other client was kicked from the channel.
4016 Implemented the handling of the notify type to both client
4019 Implemented silc_server_send_notify_kicked to send the KICKED
4020 notify. It is used to send it to the server's primary router.
4022 * Implemented the KICK command into server and client.
4024 * Added `query' argument to the silc_idlist_get_client function
4025 to indicate whether to query the client from server or not if
4028 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4029 to indicate that the client is not channel founder.
4033 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Removed the rng context from SilcPacketContext structure and
4036 changed that the packet routine uses the Global RNG API.
4038 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4040 * Added support for quit message that client can "leave" on the
4041 channel when it quits the SILC. It is ditributed inside the
4042 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4044 Added silc_server_free_client_data that will take the
4045 signoff message as argument.
4047 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4049 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Updated parts of the protocol specification to keep it up
4054 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4057 payloads in one packet.
4059 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4060 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4061 use now the new List flag.
4063 * Also deprecated the following packet types: REPLACE_ID,
4064 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4066 * Added list support for Notify packet in server.
4068 * Added silc_server_send_notify_channel_change to send the
4069 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4070 the silc_server_send_replace_id.
4072 * Added silc_server_send_notify_nick_change to send the
4073 NICK_CHANGE notify type. Deprecates the function
4074 silc_server_send_replace_id.
4076 * Added silc_server_send_notify_join to send the JOIN notify type.
4077 Deprecates the function silc_server_send_new_channel_user.
4079 * Added silc_server_send_notify_leave to send LEAVE notify type.
4080 Deprecates the function silc_server_send_remove_channel_user.
4082 * Added silc_server_send_notify_cmode and
4083 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4084 types. Deprecates the silc_server_send_set_mode function.
4086 * Added SERVER_SIGNOFF notify type to indicate that server has
4087 quit. This means that all clients on the channel from that
4088 server will drop. This can be also used when netsplit happens.
4090 Deprecated REMOVE_ID packet type since it is not needed anymore
4093 Added silc_server_send_notify_server_signoff to send the
4094 SERVER_SIGNOFF notify type. Deprecates the function
4095 silc_server_send_remove_id.
4097 Added also silc_server_send_notify_signoff to send the
4098 SIGNOFF notify type.
4100 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4101 SILC protocol from this day on. Changed the protocol
4102 specification as well.
4104 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4105 notify type. It is used between routers to notify about
4106 topic changes on a channel.
4108 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4111 * Partly updated the protocol specification to comply with the
4112 changes now made. It is still though a bit outdated.
4114 * The JOIN notify type now takes one extra argument <Channel ID>.
4115 The packet used to be destined to the channel but now the
4116 JOIN type may be sent as list thus it is impossible to
4117 destine it to any specific channel. By adding this argument
4118 it is again possible.
4120 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Added CREDITS file. The CHANGES and CREDITS file will appear
4123 in the distribution as well.
4125 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4128 types in the server's silcd/packet_receive.c.
4130 * Implemented CMODE and CUMODE to work in router environment.
4132 * Fixed minor encoding and decoding buglet from the
4133 lib/silccore/silcmode.c.
4135 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4138 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4140 * Changed all SilcConfigServer* and silc_config_server* to
4141 SilcServerConfig* and silc_server_config*, respectively.
4144 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * Associated the ID (client or server ID) to the Authentication
4147 Payload to avoid any possibility of forging. Updated the
4148 protocol specification and the code accordingly.
4150 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * The RSA key length is now save to the RsaKey context in the
4153 key generation process in lib/silccrypt/rsa.c. The key length
4154 is now used to figure out the maximum size of the block allowed
4155 to be encrypted/signed.
4157 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4158 is equivalent to the silc_mp_mp2bin but does not allocate any
4161 * Changed silc_mp_mp2bin API to take length argument. If it is
4162 non-zero then the buffer is allocated that large. If zero, then
4163 the size is approximated using silc_mp_sizeinbase, which however
4166 * Created Global RNG API which is global RNG that application can
4167 initialize. After initializing, any routine anywhere in the
4168 code (including library) can use RNG without allocating a new
4169 RNG object. This was done to allow this sort of use of the
4170 RNG in code that has no chance to allocate RNG object. All
4171 applications currently allocate this and many routines in the
4172 library use this. Affected file lib/silccrypt/silcrng.[ch].
4174 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4175 it to use the Global RNG API.
4177 * Defined Authentication Payload into protocol specification that
4178 is used during SILC session to authenticate entities. It is
4179 used for example by client to authenticate itself to the server
4180 to obtain server operator privileges.
4182 Implemented this payload into the lib/silccore/silcauth.[ch].
4183 Implemented also routines for public key based authentication
4184 as the new protocol specification dictates.
4186 Moved definitions of different authentication methods from
4187 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4189 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4190 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4191 silc_pkcs_verify_with_hash functions into the file
4192 lib/silccrypt/silcpkcs.[ch].
4194 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * The client entry's userinfo pointer must be always valid.
4197 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4198 will fail since it requires the userinfo. Now, the userinfo
4199 is allocated as "" if actual userinfo does not exist. Actually,
4200 it must exist and it is totally Ok to drop client connections
4201 that does not announce the userinfo. However, we will make
4202 this workaround for now.
4204 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4205 to return the remote port by socket.
4207 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4210 SILC_SERVER_PENDING_EXEC and added an new macro
4211 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4212 data or when error occurs while processing the pending command.
4214 Added new argument `destructor' into silc_server_command_pending
4215 and to the SilcServerCommandPending object. This destructor is
4216 now called after calling the pending callback or if error occurs
4217 immediately. If error occurs the actual pending callback won't
4218 be called at all - only the destructor. The destructor may be
4219 NULL if destructor is not needed.
4221 All this applies for client library code as well. Similar
4222 changes were made there as well for the pending commands.
4224 In the client, the application must now allocate the
4225 SilcClientCommandContext with the silc_client_command_alloc
4228 * Added reference counter to the SilcServerCommandContext. Added
4229 function silc_server_command_alloc and silc_server_command_dup
4232 Same type of functions added to the client library for the same
4235 * Removed the cmd_ident from IDListData away since it is now
4236 global for all connections. It is the command identifier used
4237 in command sending and with pending commands. The affected file
4240 * Added reference counter to the SilcSocketConnection objecet to
4241 indicate the usage count of the object. The object won't be
4242 freed untill the reference counter hits zero. Currently only
4243 server uses this, and client ignores it. The client must be
4244 set to use this too later. The affected files are
4245 lib/silccore/silcsockconn.[ch]. Added also the function
4246 silc_socket_dup to increase the reference counter.
4248 This was mainly added because it is possible that the socket
4249 is removed underneath of pending command or other async
4250 operation. Now it won't be free'd and proper DISCONNECTING
4251 flags, etc. can be set to avoid sending data to connection that
4252 is not valid anymore.
4254 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4255 the connection. After that it sets SILC_SET_DISCONNECTED.
4256 It is, however, possible that the socket data is not still freed.
4257 The silc_server_packet_process now checks that data is not
4258 read or written to connection that is DISCONNECTED. The socket
4259 get's freed when the reference counter hits zero.
4261 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Changed the client operation API: channel_message operation's
4264 `sender' is now the client entry of the sender, not the nickname
4265 and the `channel' is the channel entry, not the channel name.
4267 In the private_message operation the `sender' is now also the
4268 client entry of the sender not the nickname.
4270 Affected file is lib/silcclient/ops.h and all applications
4271 using the client operations.
4273 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Moved the calling of ops->connect() from connect_to_server_final
4276 into receive_new_id functin since that is the point when the
4277 client is actually allowed to send traffic to network. The
4278 affected file is lib/silcclient/client.c.
4280 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4283 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4284 (if needs broadcasting) instead of broadcasting the packets one
4285 by one which would make a burst in the network traffic.
4287 * Added `broadcast' argument to the functions in silcd/server.[ch]
4288 silc_server_create_new_channel[_with_id] to indicate whether
4289 to send New Channel packet to primary router.
4291 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Added new function into the silcd/server.[ch] files:
4294 silc_server_create_new_channel_with_id to create new channel with
4295 already existing Channel ID.
4297 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4298 lib/silccore/silcpacket.h. This packet is used t send list of
4299 Set Mode payloads inside one packet. Server uses this to set
4300 the modes for the channels and clients on those channels, that it
4301 announced to the router when it connected to it. The protocol
4302 specification has been updated accordingly.
4304 * The silc_server_new_channel did not handle the packet coming
4305 from normal server as it normally does not send that. However,
4306 when it announces its channels it does send it. Implemented
4307 the support for that.
4309 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4310 into the file lib/silccore/id.h.
4312 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Fixed memory leaks in the functions silc_idlist_del_client,
4315 silc_idlist_del_channel and silc_idlist_del_server in the file
4316 silcd/idlist.c. All of those leaked like a sieve.
4318 * Fixed some small memory leaks in the client's function
4319 silc_client_notify_by_server.
4321 * Added functions into silcd/server.c: silc_server_announce_clients,
4322 silc_server_announce_channels and silc_server_announce_server.
4323 These functions are used by normal and router server to announce
4324 to its primary router about clients, channels and servers (when
4325 router) that we own. This is done after we've connected to the
4328 These functions effectively implements the following packet types:
4329 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4330 and SILC_PACKET_NEW_ID_LIST.
4332 * Added new functions into the silcd/packet_receive.[ch]:
4333 silc_server_new_id_list, silc_server_new_channel_list and
4334 silc_server_new_channel_user_list to handle the incoming
4335 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4337 * Added support of changing Channel ID in the function
4338 silc_server_replace_id. If the server that announces a channel
4339 to the router already exists in the router (with same name but
4340 with different Channel ID), router is responsible to send
4341 Replace ID packet to the server and force the server to change
4342 the Channel ID to the one router has.
4344 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4345 client that the Channel ID has been changed by the router. The
4346 normal server sends this to the client. Client must start using
4347 the new Channel ID as the channel's ID.
4349 Implemented handling of this new type into lib/silcclient/client.c
4350 into the function silc_client_notify_by_server.
4352 * Added new function silc_idlist_replace_channel_id into the files
4353 silcd/idlist.[ch] to replace the Channel ID.
4355 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Call silc_server_command_identify_check always when processing
4358 the IDENTIFY command in silcd/command.c
4360 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4363 send keepalive packets. The packet can be sent by clients,
4364 servers and routers.
4366 Added function silc_socket_set_heartbeat into the file
4367 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4368 If not set, the heartbeat is not performed. The actual
4369 heartbeat is implemented in the low level socket connection
4370 library. However, application is responsible of actually
4373 Added silc_server_send_heartbeat to send the actual heartbeat
4374 packet into silcd/packet_send.[ch]. Server now performs
4375 keepalive with all connections.
4377 * Added silc_task_get_first function into lib/silcutil/silctask.c
4378 to return the timeout task with shortest timeout. There was a bug
4379 in task unregistration that caused problems. TODO has been
4380 updated to include that task system must be rewritten.
4382 * The client library will now resolve the client information when
4383 receiving JOIN notify from server for client that we know but
4384 have incomplete information.
4386 * Rewrote parts of silc_server_remove_from_channels and
4387 silc_server_remove_from_one_channel as they did not remove the
4388 channel in some circumstances even though they should've.
4390 * Encryption problem encountered in server:
4392 The LEAVE command used to send the Channel Key packet to the
4393 router immediately after generating it. However, the code
4394 had earlier sent Remove Channel user packet but not immediately,
4395 ie. it was put to queue. The order of packets in the router
4396 was that Channel Key packet was first and Remove Channel User
4397 packet was second, even though they were encrypted in the
4398 reverse order. For this reason, MAC check failed. Now, this
4399 is fixed by not sending the Channel Key packet immediately but
4400 putting it to queue. However, this is more fundamental problem:
4401 packets that are in queue should actually not be encrypted
4402 because packets that are sent immediately gets encrypted
4403 actually with wrong IV (and thus MAC check fails). So, packets
4404 that are in queue should be encrypted when they are sent to
4405 the wire and not when they put to the queue.
4407 However, the problem is that the current system has not been
4408 designed to work that way. Instead, the packet is encrypted
4409 as soon as possible and left to the queue. The queue is then
4410 just purged into wire. There won't be any fixes for this
4411 any time soon. So, the current semantic for packet sending
4414 o If you send packet to remote host and do not force the send
4415 (the packet will be in queue) then all subsequent packets to the
4416 same remote host must also be put to the queue. Only after the
4417 queue has been purged is it safe again to force the packet
4420 o If you send all packets immediately then it safe to send
4421 any of subsequent packets through the queue, however, after
4422 the first packet is put to queue then any subsequent packets
4423 must also be put to the queue.
4425 Follow these rules and everything works fine.
4427 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added new function silc_server_remove_clients_by_server to
4430 remove all client entries from ID list when the server connection
4431 is lost. In this case it is also important to invalidate all
4432 client entires as they hold the invalid server entry. This
4433 fixes fatal bug when server has lost connection and will reconnect
4436 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Made some sanity checks to silc_server_daemonise like to check
4439 whether the requested user and group actually exists.
4441 * Added sanity check to SKE's silc_ske_responder_finish to check
4442 that the public and private key actually is valid.
4444 * Invalidate the client's nickname when receiving Replace ID
4445 packet and the Client ID is being replaced. This means that the
4446 server will query the nickname if someone needs it (client)
4449 * Sort the ID Cache in client library when the ID Cache data
4450 has changed (needs sorting).
4452 * Do not allow for SILC client to create several connections to
4453 several servers. The client does not support windows right now
4454 and generating multiple connections causes weird behaviour.
4456 Irssi-silc client does support windows and can handle several
4457 connections without problems, see: www.irssi.org and SILC plugin.
4459 * Fixed some places where client was added to the IDList. The
4460 rule of thumb is following (in order to get everything right):
4461 If the client is directly connected local client then the
4462 `connection' argument must be set and `router' argument must be
4463 NULL to silc_idlist_add_client function. If the client is not
4464 directly connected client then the `router' argument must
4465 bet set and the `connection' argument must be NULL to the
4466 silc_idlist_add_client function.
4468 * The funtion silc_server_packet_send_local_channel actually did
4469 not check whether the client was locally connected or not. It
4470 does that now. Fixed a bug related to LEAVE command.
4472 * Fixed Remove Channel User payload parsing bug in server's
4473 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4475 * The server's silc_server_save_channel_key now checks also the
4476 global ID list for the channel as it might not be in the local
4477 list. Fixed a bug related to LEAVE command.
4479 * Is this the end of the [<unknown>] buglet that has been lurking
4480 around for a long time? A little for loop fix in server's
4481 silc_server_command_whois_parse that is used by both IDENTIFY
4482 and WHOIS command. At least, this was a clear bug and a cause
4483 of one type of [<unknown>] buglet.
4485 * WHOIS and IDENTIFY commands call the function
4486 silc_server_command_[whois/identify]_check function even if
4487 we are not router server.
4489 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Added --with-gmp configuration option. If set the GMP
4492 is always compiled in the SILC source tree. If not set then
4493 it is checked whether the system has the GMP3 installed. If
4494 it has then the GMP won't be compiled (the system's headers
4495 and library is used), if it doesn't have it then the GMP is
4496 compiled in the SILC source tree.
4498 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Changed RSA private exponent generation to what PKCS #1
4501 suggests. We try to find the smallest possible d by doing
4502 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4503 not security fix but optimization.
4505 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Added new config entry [Identity] to fork the server and run
4508 it as specific user and group. A patch from Bostik.
4510 * Imported Dotconf configuration library into lib/dotconf.
4511 This will be used to create the SILC configuration files later.
4512 It will appear in the distsribution after this commit.
4514 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * A big code auditing weekend happening. Auditing code for
4517 obvious mistakes, bugs and errors. Also, removing any code
4520 Removed files for being obsolete:
4522 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4523 inline in the file lib/silcutil/silcbuffer.h)
4525 o lib/silcutil/silcbufutil.c (the header has inline versions)
4527 Changed code to fix possible error conditions:
4529 o The buffer formatting routines now check that the destination
4530 buffer really has enough space to add the data. This applies for
4531 both buffer formatting and unformatting
4532 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4533 unformatting was changed to accomodate following rules:
4534 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4535 sent to the function while XXX_*STRING will not allocate or copy
4536 the data into the buffer. Instead it sets the pointer from the
4537 buffer into the pointer sent as argument (XXX_*STRING used to
4538 require that the pointer must be allocated already). This change
4539 makes this whole thing a bit more consistent and more optimized
4540 (note that the data returned in the unformatting with XXX_*STRING
4541 must not be freed now). The routines return now -1 on error.
4543 o Tried to find all code that use buffer_format and buffer_unformat
4544 and added return value checking to prevent formatting and
4545 especially unformatting errors and possible subsequent fatal
4548 o Changed ske->x and ske->KEY to mallocated pointers in
4549 lib/silcske/silcske.h. Fixed possible data and memory leak.
4551 o Added return value checking to all *_parse* functions. Fixed
4552 many memory leaks as well.
4554 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4555 so that buffer overflows would not happen. All code now also
4556 checks the return value as it can fail.
4558 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Added reconnection support to server if the normal server looses
4561 its connection to the router (for example if router is rebooted).
4562 The server performs normal reconnection strategy implemented
4563 to the server. Affected file silcd/server.c.
4565 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added new packet type SILC_PACKET_SET_MODE that is used to
4568 distribute the information about changed modes (for clients,
4569 channels and clients channel modes) to all routers in the
4570 network. Updated the protocol specification accordingly.
4572 Added functions into silcd/packet_send.c and
4573 silcd/packet_receive.c: silc_server_send_set_mode,
4574 silc_server_set_mode.
4576 Added new files silcmode.[ch] into lib/silccore that implements
4577 the encoding and decoding of Set Mode Payload. Added new type
4578 SilcSetModePayload. Moved the definitions of different modes
4579 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4581 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Oops, a little mistake in server's connection authentication
4584 protocol. The protocol is not ended with FAILURE but with
4585 SUCCESS if the authentication is Ok. :) Affected file is
4588 * Implemented NICK_CHANGE notify handling in server in the file
4589 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4590 the local clients on the channel. After the changing nickname
4591 in router environment snhould work and the [<unknown>] nickname
4592 should appear no more.
4594 The silc_server_replace_id function that receives the Replace ID
4595 payload now sends the NICK_CHANGE notify type also in the file
4596 silcd/packet_receive.c
4598 * Changed WHOIS and IDENTIFY command to support the maximum amount
4599 of arguments defined in protocol specs (3328 arguments). This
4600 fixed a bug that caused problems when there were more than three
4603 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Added extra parameter, command identifier, to the
4606 silc_client_send_command so that explicit command identifier
4609 Changed that ID list routines uses specific command identifier
4610 when sending WHOIS/IDENTIFY requests to the server so that they
4611 can be identified when the reply comes back.
4613 Affected files lib/silcclient/command.[ch],
4614 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4616 * Added `sender' argument to silc_server_packet_send_to_channel
4617 to indicaet the sender who originally sent the packet to us
4618 that we are now re-sending. Ignored if NULL. Affected file
4619 silcd/packet_send.[ch].
4621 * Added some server statistics support in silcd/server_internal.h
4622 SilcServerStatistics structure and around the server code. Also
4623 send some nice statistics information when client is connecting
4626 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Fixed channel ID decoding in server's JOIN command reply in
4629 silcd/command_reply.c
4631 * Fixed braodcasting of replace ID payload to not to send it if
4632 we are standalone server in silcd/packet_receive.c.
4634 * Fixed all channel message sending routines to not to send
4635 packets to clients that has router set, since they are routed
4636 separately in the same function earlier. Affects file
4637 silcd/packet_send.c and all channel packet sending functions.
4639 * In USERS reply, res_argv[i] are not allocated, the table
4640 is allocated. Thus changed that free the table, not its
4643 * In server's whois_check and identify_check if the client is
4644 locally connected do not send any WHOIS commands - they are not
4647 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Fixed some minor bugs in client when sending WHOIS command. The
4650 arguments was in wrong order.
4652 * Removed statis function add_to_channel from server in
4653 silcd/command.c that was previously used with the joining but
4656 * Tested USERS command in router environment successfully with two
4657 routers, two servers and two clients.
4659 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Reorganized the USERS command and command reply in client library
4662 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4663 When the command is given by user we register a pending command
4664 callback that will reprocess the command after the reply has been
4665 received from the server. When reprocessing the packet we then
4666 display the information. Thus, the USERS information is displayed
4667 now in the command callback instead of in the command reply
4668 callback. The processing of the command is same as previously
4669 when server has sent the command reply in the JOINing process.
4671 * Added to USERS command in silcd/command_reply.c to join the client,
4672 we didn't use to know about, to the channel after we've created
4673 a client entry for it. Also, for clienet we did know already still
4674 check whether it is on the channel or not and add it if not.
4676 * Removed silc_server_command_join_notify as the function and its
4679 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Changed the client's pending command handling to the same as the
4682 server's pending command handling. It is also now possible to
4683 execute command reply functions from other command reply
4684 function as the function callbacks for commands and command
4685 replies are one and same. The pending commands are not static
4686 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4687 in client connection context. Thus, pending commands are server
4688 connection specific as it is convenient.
4690 Changed the function silc_client_command_pending and
4691 silc_client_command_pending_del and added new function
4692 silc_client_command_pending_check. Removed the
4693 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4696 * Added cmd_ident, current command identifier, to the client
4697 connection context in lib/silcclient/client.h to keep track on
4698 command identifiers used in command sending. Client's command reply
4699 function handling now supports the mandatory command identifiers.
4701 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4702 funtions in client to fully support pending command callbacks.
4704 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4705 as one of the arguments to the application in the command reply
4708 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4709 before first releasing SILC but came back. Now it is removed again
4710 and should come back nomore. The FORWARDED flag was used only
4711 by the JOINing procedure by forwarding the command packet to router.
4712 Now, the JOINing procedure has been changed to more generic (due
4713 to various router environment issues) and FORWARDED is not needed
4714 anymore for anything. The protocol specification is yet to be
4717 Now, removed silc_server_packet_forward from server and the flag
4718 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4720 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4722 * Renamed NAMES command to USERS command. The NAMES was named that
4723 due to historical reasons. Now it is renamed. Also, rewrote
4724 parts of the USERS command. The nickname list is not sent anymore
4725 by the server. Only Client ID and mode lists are sent in the USERS
4726 command. Changed this also to the protocol specification.
4728 The client now resolves the names and stuff after it receives
4729 the USERS list from the server when joining to the channel.
4731 * WHOIS and IDENTIFY commands has been changed to support multiple
4732 Client ID's per command. One can now search for multiple users
4733 in the network by sending only one WHOIS or IDENTIFY command.
4734 Changed the code and the protocol specifications.
4736 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4737 uses silc_server_command_whois_parse to parse the request. */
4739 * If normal server, do not parse the WHOIS and IDENTIFY requests
4740 before sending it to the router. Saves some time.
4742 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Fixed JOIN command on client library. Wrong number of arguments
4745 used to crash the client.
4747 * Added silc_server_channel_has_global function to check whether
4748 channel has global users or not.
4750 * Added silc_server_channel_has_local function to check whether channel
4751 has locally connected clients on the channel.
4753 * The silc_server_remove_from_one_channel now checks whether the
4754 channel has global users or not after given client was removed from
4755 the channel. It also checks whether the channel has local clients
4756 on the channel anymore. If it does not have then the channel entry
4757 is removed as it is not needed anymore.
4759 * The silc_server_notify now checks on JOIN notify whether the joining
4760 client is one of locally connected or global. If it is global then
4761 the channel has now global users on the channel and that is marked
4762 to the channel entry. Also, it now saves the global client to
4763 global list who is joining and JOINs it to the channel. This is
4764 for normal server, that is.
4766 Changed silc_server_send_notify_on_channel,
4767 silc_server_packet_relay_to_channel and
4768 silc_server_packet_send_to_channel check if we are normal server
4769 and client has router set (ie. global client) do not send the
4770 message to that client, as it is already routed to our router.
4772 * Implemented LEAVE notify type handling in silc_server_notify
4775 * Tested LEAVE command in router environment successfully. Tested
4776 with two routers, two servers and two clients.
4780 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4782 * Implemented SIGNOFF notify type handling in silc_server_notify
4785 * silc_server_remove_id now removes the client entry from all channels
4786 it has joined and thusly sends SIGNOFF notify type.
4788 * Rewrote the NAMES list generation in server by removing two excess
4789 loops. The lists are created now inside one loop.
4791 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4793 * silc_server_remove_channel_user checks now also global list
4794 for channel and client.
4796 * silc_server_new_channel_user checks now both local and global
4797 list for channel and client. Fixed a bug in client id decoding.
4798 Used to decode wrong buffer.
4800 * silc_server_channel_message checks now both local and global
4801 list for channel entry.
4803 * Tested channel joining (hence JOIN) in router environment
4804 successfully. Tested with two routers, two servers and two
4807 * Tested channel message sending in router environment successfully.
4809 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added silc_server_save_channel_key into server.[ch] to save the
4812 received channel key in Channel Key payload processing. It is
4813 also used in JOIN command reply handling.
4815 Equivalent function silc_client_save_channel_key added into
4816 client.[ch] into client library.
4818 * Changed JOIN command reply to send information whether the channel
4819 was created or not (is existing already) and the channel key
4820 payload. Changed protocol specs accordingly.
4822 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4823 the request was sent by ID and not by nickname. Crashed on
4826 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4829 now correctly save the received data.
4831 * silc_server_free_sock_user_data now notifies routers in the
4832 network about entities leaving the network.
4834 At the same time implemented functions silc_server_remove_id
4835 and silc_server_send_remove_id to receive and send REMOVE_ID
4836 packets. The packet is used to notify routers in the network
4837 about leaving entities. The ID removed will become invalid in
4840 * Added function silc_idlist_del_server into server. Removes and
4841 free's server entry from ID list.
4843 * silc_server_private_message function now checks, if we are router,
4844 that the destination ID really is valid ID, naturally.
4846 * In router when NEW_ID packet is received (for new client) the
4847 hash of the Client ID is saved in the ID Cache but the
4848 client->nickname is set to NULL, instead of putting the hash
4851 IDENTIFY command now also checks that client->nickname must be
4852 valid. If it is not if will request the data from the server who
4853 owns the client. Added new function
4854 silc_server_command_identify_check.
4856 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4857 to set the command to already allocated Command Payload.
4859 * Tested private message sending in router environment with two
4860 routers, two servers and two clients. Fixed minor bugs and now
4863 * Fixed segfault from client's NAMES command. Used to crash if
4866 * Forwarded packets must not be routed even if it is not destined
4867 to the receiver. Changed server code comply with this.
4869 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * Added `require_reverse_mapping' boolean value to ServerParams
4872 structure. If TRUE (not default) the server will require that
4873 the connecting host has fully qualified domain name.
4875 If the reverse mapping is not required and hostname could not be
4876 found the IP address is used as hostname.
4878 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Implemented version string checking to both client and server.
4881 The check is incomplete currently due to the abnormal version
4882 strings used in development version of SILC.
4884 * Changed all command functions in server to use the new
4887 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Changed char *data to unsigned char *data in ID Cache system to
4890 support binary data as ID Cache data. Changed code to support
4891 binary data in lib/silccore/idcache.c.
4893 * Renamed silc_server_packet_relay_command_reply to
4894 silc_server_command_reply as it is normal packet receiving
4895 function. Rewrote the function to accept command replys for
4896 servers and not only for clients.
4898 * Mark remote router always as registered server if we are connecting
4899 to it. Otherwise, commands sent by the router to us are ignored.
4901 * All ID List find routines now returns the ID Cache Entry pointer
4902 as well if requested.
4904 * WHOIS command works now in router environment, tested with two
4905 routers, two servers and two clients.
4907 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4908 in router environment (as it is almost equivalent to WHOIS) but
4909 hasn't been tested thoroughly. Added new functions:
4911 silc_server_command_identify_parse
4912 silc_server_command_identify_send_reply
4913 silc_server_command_identify_from_client
4914 silc_server_command_identify_from_server
4916 * Disabled route cache adding because adding two different ID's with
4917 same IP replaces the old cache entry thus giving wrong route.
4918 The entry->router->connection is always the fastest route anyway
4919 so route cache may not be needed. Of course, new routes maybe
4920 established after receiving the ID when the entry->router->connection
4921 might not be anymore the most optimal.
4923 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Add route cache for received ID for fast routing.
4927 * Added silc_server_packet_route to route received packet on router
4928 that is not destined to us.
4930 * Renamed silc_server_get_route to silc_server_route_get.
4932 * Added id_string and id_string_len fields into SilcServer to
4933 include encoded ServerID for fast comparing without excess
4934 encoding of the ID's.
4936 * Cleaned up WHOIS command on server side. Added following static
4939 silc_server_command_whois_parse
4940 silc_server_command_whois_check
4941 silc_server_command_whois_send_reply
4942 silc_server_command_whois_from_client
4943 silc_server_command_whois_from_server
4945 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4946 arguments in command replies. All command functions should be
4947 updated to use this macro.
4949 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4951 * Minor typo fixes on command reply handling on server.
4953 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Added silc_server_command_add_to_channel internal routine to add
4956 the client to the channel after router has created the channel and
4957 sent command reply to the server.
4959 * Added generic silc_server_send_command to send any command from
4962 * Use static buffer with ID rendering instead of duplicating data.
4964 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Fixed a channel user mode bug when joining to a channel server gave
4967 everybody channel founder rights, oops.
4969 * We mark ourselves as the router of the incoming server connection
4970 if we are router ourselves. This way we can check in some packet
4971 sending functions whether it is locally connected server. For
4972 incoming router connections we put NULL.
4974 * For router sending packets locally means now always sending the
4975 packet cell wide; to local clients and local servers. For normal
4976 server sending packet locally means sending it to only local
4979 * Fixed the JOIN command to really work in router environment. If the
4980 channel is created it is always created by the router. Router is
4981 also responsible of making the initial joining to the channel,
4982 sending JOIN notify to the sending server and distributing
4983 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4984 does not exist server doesn't do anything else but forward the
4985 command to the router which performs everything.
4987 * Added silc_server_send_channel_key function to send the Channel Key
4990 * Added silc_server_create_channel_key to create new channel key. The
4991 channel key is now re-generated everytime someone joins or leaves
4992 a channel, as protocol dictates. Note: channel->key_len is the
4995 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4997 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4998 packet_receive.[ch] to separate packet sending and receiving
4999 routines. The server.[ch] now includes everything else including
5000 actual packet processing (writing and reading data) and other
5003 Renamed silc_server_private_message_send_internal to
5004 silc_server_send_private_message. The routine is still though
5005 used only to relay private messages as server does not send
5006 private messages itself.
5008 Renamed silc_server_new_channel to silc_server_create_new_channel
5009 and added new function sicl_server_new_channel that handles the
5010 incoming New Channel packet. Added also new sending function
5011 silc_server_send_new_channel to send New Channel Payload.
5013 * Added new function silc_server_notify to process incoming notify
5014 packet to the server/router. Server may then relay the notify
5015 to clients if needed.
5017 * Added new function silc_server_new_channel_user to process incoming
5018 New Channel User packet. Router will redistribute the packet and
5019 send JOIN notify to its local clients and locally connected servers
5020 if needed. Normal server will send JOIN notify to its local client
5021 on same channel when received this packet. Added also corresponding
5022 sending function silc_server_send_new_channel_user to sent the
5025 * Added boolean route argument to send_notif_to_channel and
5026 packet_send_to_channel functions to attempt to route the packet
5027 if it is TRUE and send only locally if it is FALSE.
5029 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5031 * silc_server_replace_id now broadcasts the received replace ID
5032 packet if it is not broadcast packet already. The router must
5033 broadcast to inform other routers about changed ID.
5035 * Added backpointer to server's router into SilcServer context in
5036 silcd/server_internal.h.
5038 * Fixed silc_server_packet_broadcast to send correct broadcast
5041 * The channel key is now distributed to the local client as soon
5042 as it is received from the router (in router environment) so that
5043 no other packet may be sent for the channel until client has
5046 * silc_server_remove_channel_user now broadcasts the received
5047 Remove Channel User packet if it is not broadcast packet already.
5048 The router must broadcast to inform other routers about removed
5051 * Added users field into SilcPacketContext that is a reference count
5052 of the context. One can increase the reference count by calling
5053 silc_packet_context_dup which is now changed to just increase the
5054 reference count instead of duplicating the data. The reference
5055 count is decresed by calling silc_packet_context_free that will
5056 free the data after the reference count hits zero.
5058 For now on the packet context and everything allocated into it
5059 (including the raw packet from network) must be freed by calling
5060 the new silc_packet_context_free function. Added also new function
5061 silc_packet_context_alloc that must be used now to allocate the
5062 context. This also means that if a routine is asynchronous from
5063 silc_[client/server]_packet_parse_type the packet context must
5064 be duplicated by calling silc_packet_context_dup. Otherwise it
5065 gets free'd after silc_[client/server]_packet_parse_type returns.
5066 Also, one must remember that if packet is duplicated then its
5067 reference count must be decresed by calling the free function as
5068 many times as it was duplicated.
5070 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5071 from both client and server.
5073 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Made joining to a channel working in router environment.
5077 * Cleaned up JOIN command on server side and create function
5078 silc_server_command_join_channel internal routine to make the
5081 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Changed silc_command_pending list to SilcDList. Also, added
5084 `ident' field to SilcServerCommandPending structure to identify
5085 the reply and to call correct callback.
5087 Added silc_server_command_pending_check function to replace the
5088 corresnponding macro. The silc_command_pending list is not
5091 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5092 to set identifier to previously allocated Command Payload. It
5093 is used to set identifier for command when resending Command
5096 * Added silc_command_payload_encode_payload to encode Command
5097 Payload buffer from SilcCommandPayload structure.
5099 * Added silc_argument_payload_encode_payload to encode Argument
5100 payload buffer from SilcArgumentPayload structure.
5102 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Changed WHOIS command to support router connection on server side.
5105 The whois request is always sent to router unless the server is
5106 standalone server. After server has received the reply from the
5107 router will it send the reply to the client.
5109 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5110 broadcast received broadcast packet. The function is used only
5111 by router. The broadcast packet is always sent to the router's
5114 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5115 render given ID to printable string, for log files for example.
5117 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Made basic router to router connections working. At least they
5120 can now connect to each other but nothing really works the way
5121 they are supposed - yet.
5123 * Added new initiator token to RouterConnection configuration
5124 file in silcd/serverconfig.[ch]. It is used to tell whether we
5125 are the initiator to the remote router or whether we'll expect
5126 the other end to connect.
5128 * Moved registering of listener task to silc_server_init, hence
5129 the server starts listenning as soon as it is run, even if it
5130 does not have connections to other routers. Let's see how well
5133 * Changed default connection retry timeouts for more suitable in
5136 * Removed cipher and such arguments from silc_idlist_add_client
5137 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5138 Added new function silc_idlist_add_data to add the keys and stuff
5141 * Added SilcIDListData structure and added it to SilcClientEntry
5142 and SilcServerEntry as their first field in the structure. This
5143 way we can explicitly cast the ID entries to the SilcIDListData
5144 structure and get common data for the entries. In past, we had
5145 to first check what type of connection it is and then cast it to
5146 correct ID entry type. Now, we can directly cast the opaque
5147 pointer to the SilcIDListData (no matter what ID entry it actually
5148 is) and get the data needed.
5150 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5153 in some circumstances even if threre were timeout tasks, though not
5154 IO tasks, but tasks anyway. Now fixed.
5156 * Defined SilcServerConnection structure to hold connection specific
5157 stuff about directly connected servers and routers. The definition
5158 is currently in silcd/server_internal.h. I thought about having
5159 a bit more important role fro this struct but for now it is used
5160 only when connecting to other server (or router actually).
5162 * Added connecting retry support in server when connecting to
5163 router(s). The retry feature implement exponential backoff
5164 algorithm. Also, added SilcServerParams structure to hold default
5165 parameters for server. For now, it include these retry settings
5166 and are hard coded. After server is moded to be as Silc Server
5167 Library this structure will be more important.
5169 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Changed client librarys channel->clients table to SilcList and
5172 changed code accordingly.
5174 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Changed client's channel table to SilcList and changed code
5177 accordingly. Also changed SilcChannelClientEntry to include back-
5178 pointer to the channel so that client entry can use that structure
5179 as list as well and we have fast cross-reference to the channel.
5180 This change dramatically decreased the complexity of channel
5181 handling with client entry and vice versa (removed one extra
5182 loop when searching for channel entry from many functions).
5184 * Changed server->sim from table to SilcDList and changed code
5187 * NAMES command can now be used from user interface. It will show
5188 the user list on the channel, neatly.
5190 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5191 Code now saves realname of the user if it becomes available.
5193 * Renamed configure.in to configure.in.pre and made ./prepare
5194 script to automatically add correct version string to
5195 configure.in which it creates from configure.in.pre.
5197 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * NAMES command reply now shows users mode with the nickname when
5202 * Moved silc_client_ch[u]mode[_char] functions from
5203 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5204 place sucks, they are utility functions and should be in some
5207 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5209 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5212 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Added TRQ (efficient deque and list library) into lib/trq. This is
5217 a very good list library that is currently used in the SILC. Defined
5218 SilcList API over the library because I didn't like the API very
5219 much. See lib/trq/silclist.h for the API and examples of how to
5220 use the API. Fixed various places in the code to use the new
5221 SilcList API. The SilcList is meant for lists that has a structure
5222 already defined as a list. It is not suitable to add just some
5223 context to the list (in TRQ, the context is the list actually).
5225 So, I defined SilcDList that can be used for the purpose where
5226 predefined list structure does not exit. This can be used as
5227 such list. Now some context just can be added to the SilcDList.
5228 Currently this list is not used in the SILC just yet, though there
5229 are a lot places where this can replace dynamically allocated
5230 tables and I will fix these places, later, to use SilcDList.
5231 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5232 and use TRQ internally).
5234 Also fixed some annoying warning messages that the original TRQ
5235 code generated. Also minor changes to TRQ's Makefile.in.
5237 * Added support for querying by Client ID to both WHOIS and
5238 IDENTIFY commands into server, as required by the protocol.
5240 * Removed method function pointers from SilcBuffer structure. They
5241 weren't used to anything and just increased the context size for
5242 no good reason. This change also made silc_buffer_alloc and
5243 silc_buffer_free functions inline functions.
5245 * Disabled command flooding detection support until it's fixed so
5246 that it accepts commands in but does not execute them more than once
5249 * Added silc_net_localhost(), to return local hostname, into
5250 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5251 that must be initialized before calling silc_client_init.
5253 * Added new function: silc_server_send_notify_on_channels to send
5254 notify messages to all channels client has joined. It is assured
5255 that the message is sent only once per client.
5257 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5258 lib/silcutil/silcutil.[ch] as silc_format function. The new
5259 function is generic and is used by server as well, not only by
5260 the logging routines.
5262 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5263 the provided version string was not acceptable. Added new function:
5264 silc_ske_check_version into lib/silcske/silcske.h. The function
5265 must be implemented by the application (client or server) and it
5266 does not reside in the SKE library. The function checks the version
5267 string remote end sent.
5269 * Added back pointers (to opaque context and to SilcSocketConnection)
5270 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5272 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5273 duplicate packet context structure.
5275 * Changed `notify' client operation to send same arguments as client
5276 receives from server except for ID's. ID's are mapped to correct
5277 ID entry and that is returned. Also, if channel entry is not sent
5278 by server but the notify is for channel the channel entry is sent
5279 to application (otherwise application doesn't know that it is for
5280 channel (library gets it from packet's Destination ID)).
5282 * Added silc_client_remove_from_channels into client library to
5283 remove a client from all channels it has joined to. Used when
5284 received SIGNOFF notify from server. Added also new function
5285 silc_client_replace_from_channels to replace old ID entry with
5286 new ID entry on all channels. Used when received NICK_CHANGE
5289 * Fixed ID Cache list handling in silc_idlist_get_client in
5290 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5291 to get (or query) client by ID.
5293 * Updated TODO list.
5295 * Added connection authentication status message defined by the
5296 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5297 support for these into the code in client and server side.
5299 * Added generic function silc_client_send_command to send any command
5300 with variable argument list. Application should use this function
5301 to send commands if the command functions provided by the library
5302 does not suite for the application's user interface needs.
5304 * Added new `failure' client operation. Application is notified about
5305 received failure packet if client is executing a protocol. In this
5306 case the protocol's execution has failed.
5308 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5309 is required by the protocol.
5311 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5312 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5315 * Added status flag to SilcSKE object to indicate realtime status
5316 of the SKE protocol.
5318 * Application receives now exactly same command reply arguments as
5319 the library receives from server. However, if ID is received the
5320 corresponding ID entry is returned to the application (eg. Client
5321 ID is mapped to correct SilcClientEntry entry and that is returned).
5322 Changed command_reply client operation due to this change.
5324 * Changed all ID's in commands and in command replys as ID Payloads.
5325 Change affected both client and server side codes.
5327 All ID's sent in SILC network (with execption of ID's in SILC
5328 Packet header) are sent in ID Payload to support variable length
5331 * Server now notifies nick changes and notifies all clients on
5332 the channels about the new nickname (about the new Client ID,
5335 * Implemented CMODE command to change channel modes. Supports all
5336 channel modes defined by the protocol specs except ban and invite
5337 lists. (Also, private channel key mode is supported but support for
5338 setting private channel key in client is missing, thus, this mode
5339 has no effect on client side (except that server requires that the
5340 client uses private channel key and normal channel traffic does not
5343 Also, invite mode works per se, but INVITE command does not work
5344 yet correctly, so you can set channel as invite only channel but
5345 inviting clients to the channel does not work (it is yet to be
5346 thought what's the best way to do it).
5348 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5349 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5350 Implemented CUMODE command to change user's mode on the channel.
5351 Supports all modes defined by the protocol specs.
5353 * Added NAMES command reply to return users modes on the channel.
5355 * Removed unnecessary and slow ciphers from lib/silccrypt.
5357 * Set SO_KEEPALIVE option to connection sockets by default.
5359 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5361 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5362 redefined the Notify Payload into protocol specs.
5364 * Added silc_id_payload_parse_id to get ID directly from raw
5367 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5369 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5370 accept searching by Client ID as well.
5372 * Added support for LEAVE and SIGNOFF notify types in client library.
5374 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5375 to parse ID Payload from raw data.
5377 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5379 * Added flags parameter into silc_ske_assemble_security_properties
5380 function in lib/silcske/silcske.[ch].
5382 * Changed notify client operation to fit better for notify messages
5383 sent by server. The notify payload received from server is now
5384 passed to the application (after parsing it to SilcNotifyPayload).
5385 It is application's responsibility to retrieve the arguments
5386 from the payload and show the message the way it wants. The message
5387 sent by server is implementation specific.
5389 * Changed public keys to comply with the protocol specification.
5390 Old public keys are not supported anymore and are not compatible.
5392 * Removed nickname from Channel Payload as the latest draft removed
5393 it. The client must resolve the nickname from the NAMES command
5394 reply received when it joined the channel.
5396 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5398 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Fixed some errors in protocol specification drafts.
5402 * Created lib/silccore/silcnotify.c to implement Notify Payload
5403 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5404 generic payloads described by protocol specifications. The file
5405 includes implementations for ID Payload and Argument Payload.
5407 * Changed Command Payload implementation to use the new Argument
5408 Payload. Changed command_xxxx_payload to command_payload_xxxx
5409 to comply with SILC coding conventions.
5411 * Added suppport for Argument Payload handling in Notify Payload
5412 implementation as protocol requires it. Added the new support
5413 into server and client lib as well.
5415 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Added support for multiple nicknames on same channel. [n] is
5418 added locally to the nickname if there are more than one same
5419 nicknames on the channel.
5421 * Server now sends all nicknames that matched WHOIS request.
5422 Client also shows the list received from server.
5424 * Added TOPIC command to client side. User can now set and show
5425 current topic on channel.
5427 * Added MOTD command to client and server. Also, server sends the
5428 motd when client connects to the server.
5430 * Changed version strings to comply ISO 8601.
5432 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Fixed protocol error handling in client library. It should now
5435 cope even if the SKE fails for some reason.
5437 * Made new protocol specification drafts for submitting to IETF.
5439 * Implemented TOPIC command to server in silcd/command.c.
5441 * Added two new notify types into lib/silccore/silcnotify.h:
5442 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5443 notify nickname change and topic setting/change on a channel.
5445 * API change of command_reply operation in client library. The
5446 application gets now the status type received from server as well.
5448 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5452 * Cras fixed and optimized the packet handling even further and
5453 it should work now. Minor change to the prototype of function
5454 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5456 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Added new function into lib/silcutil/silcschedule.[ch]:
5459 silc_schedule_with_fd to select() a specified fd. The function
5460 returns after timeout expires or data arrives or goes. The
5461 function is used by packet routines to wait that all data is
5462 received from network.
5464 * Fixed data reading from network in lib/silccore/silcpacket.c.
5465 The code now assures that all data is read from the fd and then
5466 continues packet processing. This was a bug fix since the code
5467 used to drop some data in some circumstances.
5469 * Added new function into lib/silcclient/client.[ch]:
5470 silc_client_start_key_exchange to start key exchange after
5471 connection has been established to server. The code internally
5472 now uses this funtion but its main purpose was to provide it
5473 for applications that perform their own connecting. After
5474 application has created a connection it merely calls this
5475 function to start the key exchange between client and server.
5476 The library takes care of everything else after that.
5478 Updated also lib/silcclient/README to explain the usage of
5481 * Do not send to application information that connection has
5482 been established. Application gets notified it by connect
5485 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Applied cras's patch to add silc_schedule_one function. The
5488 function runs scheduler once and returns.
5490 * Fixed the scheduler after cras messed it up. The timeout
5491 handling works now as it's supposed to work.
5493 * Added into lib/silccore/ silcnotify.h to include notify
5494 message types support. Changed silc_server_send_notify*
5495 functions, in server.[ch], to support those new notify types.
5496 Added the support for the notify types into client library,
5497 as well. Added new notify client operation into ops.h in
5500 * Changed silc_server_packet_send_to_channel to send normal
5501 packets instead of just channel message packets. The function
5502 is now used to send the notify packets to channels. It is not
5503 used to send channel message packets anymore, as server never
5506 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5507 va_arg()s as it seems to require it nowadays. I guess, if SILC
5508 is compiled with older va_arg() the new code should work anyway.
5510 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Splitted core library. Core library (lib/silccore) includes
5513 now only SILC protocol specific core (and common) components.
5514 Created new utility library (lib/silcutil) that includes more
5515 generic purpose stuff. The stuff for util library was taken
5516 from the old core library. This was minor and easy split.
5518 * Created SILC Client Library (lib/silcclient) that includes
5519 implementation of the SILC client without user interface. This
5520 was major move from silc/ directory. The code has been changed
5521 so that it is transparent towards the user interface. The
5522 silc/ directory includes now the same user interface as before
5523 and it uses the new client library. Read lib/silcclient/README.
5524 Basicly, the client library performs everything else related
5525 to SILC except user interface handling. Also, configuration
5526 files are considered to be part of user interface and library
5527 does not handle them.
5529 This change also changed a lot of structures, function naming etc.
5530 Most important change was that SilcClientWindow object was
5531 renamed to SilcClientConnection in the client library. Created
5532 also new file lib/silcclient/ops.h. Also added new files
5533 silc/local_command.[ch] and silc/client_ops.[ch].
5535 All these changes were made to make it easier for user interface
5536 designers to create what ever user interface for the SILC client
5539 It is also expected that the server will be moved to lib
5540 directory as well and SILC Server Library will be created;
5541 sometimes in the future.
5543 * Removed Local commands from lib/silccore/silccommand.h as
5544 they are application specific and new client library does not
5545 handle any of those anymore.
5547 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5548 old client implementation in silc/.
5550 * Added support for callback functions in SILC_LOG_* macros.
5551 Application can now set its own callbacks that will be called
5552 instead of using the default functions that will always print
5553 the debug messages to stderr (or stdout). Also, debugging can
5554 now be disabled by setting silc_debug to FALSE and re-enabled by
5555 setting it to TRUE. Note, that logging will still work even
5556 if debugging is disabled.
5558 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5559 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5560 silc_log_reset_debug_callbacks.
5562 * To enable debugging in silc client one must give now -d
5563 option on command line.
5565 * Changed silc_schedule_init to automatically allocate task queues
5566 if they are not allocated before calling it.
5568 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5570 * Added GMP 3.1 into math library.
5572 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5575 a channel in SILC network. The packet is used by servers and
5576 routers to notify other routers that user has left a channel.
5577 This little feature was missing until now. Added the feature
5578 to protocol specification as well.
5580 Added functions: silc_server_send_remove_channel_user and
5581 silc_server_remove_channel_user into server.[ch].
5583 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5584 lib/silccore/silcpacket.h. However, they are not implemented
5587 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Fixed joining to a channel and sending channel messages
5590 between server and router. The channel message sending should
5591 now work inside a cell.
5593 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Fixed the private message sending between server and router.
5596 The private message sending should now work inside a cell.
5598 * Added silc_server_replace_id into server.[ch] to replace
5599 existing ID in the SILC network.
5601 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5602 and silc_idlist_replace_server_id into idlist.[ch] in server.
5604 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Fixed the server to server connections. Server can again now
5607 connect to router. Router to router connections probably does
5610 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Added dynamic protocol registering support. Now protocols can
5613 registered and unregistered on the fly. Patch by cras.
5615 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Added lib/contrib directory to hold routines that some platforms
5618 don't have but are needed by SILC.
5620 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5621 into lin/contrib to provide getopt() and getopt_long() for
5622 those who don't have it.
5624 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added AWAY command to client. When away message is set and
5627 client receives a private message packet the client automatically
5628 replies to the sender with the away message.
5630 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5631 bug seemed to be the cause of recent problems when compiling
5634 * Added version detection support to SKE protocol specification
5635 and added the new changes to the SKE implementation as well.
5636 There were other minor changes in the SKE protocol as well.
5638 Many changes in lib/silcske/silcske.[ch] and in
5639 lib/silcske/payload.[ch].
5641 * Added ^U functionality, clear input line. Patch from cras.
5643 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Mainly small bugfixes on core library. Fixed some debugging
5646 logging and buffer overflow in silclog.c.
5648 * Updated config.sub and config.guess on the distribution tree.
5650 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added command lagging support in server. Client may execute
5653 commands now only once in two seconds.
5655 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Optimized packet reception. MAC computation and checking is now
5658 also more optimized. A lot previously duplicated code is now
5659 used as generic by both client and server.
5661 * Fixed key pair generation in clientutil.c
5663 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Added into lib/silccore/silcbufutil.[ch] new function;
5666 silc_buffer_realloc.
5668 * Moved generic packet sending/encryption functions to
5669 lib/silccore/silcpacket.[ch] from client and server. Some
5670 rewriting of the functions.
5672 * Moved all generic packet reception/decryption functions to
5673 lib/silccore/silcpacket.[ch] from client and server. The
5674 packet processing is now much cleaner in both client and server.
5675 These were major changes in both client and server.
5677 * Created many common functions in server to do packet sending.
5678 Previously code were duplicated a lot, this has been removed
5681 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5683 * Rewrote major parts of the ID cache system. Don't know
5684 whether it is better now or not but at least the API is more
5687 * Major rewrite on ID cache stuff on client because of the ID
5688 cache API changes. Added idlist.c to client.
5690 * Also major rewrite on ID cache stuff on server as well.
5691 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5692 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5693 in hand, instead they are all put into the ID cache system now.
5694 All server_idlist_* routines uses ID cache now instead of
5695 traversing its own lists (those lists does not exist anymore).
5696 SilcIDList though still exists. Also, SilcXXXEntry's are
5699 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5701 * Finally made the SKE implementation compliant to the protocol
5702 specification. All mp integers are now binary encoded as
5703 opposed being HEX encoded.
5705 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5708 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5709 functions: silc_[encode/decode]_pem. Also added function
5710 silc_encode_pem_file to PEM encode with newlines ('\n') for
5713 * SILC public keys are now encoded either PEM or binary. Same
5714 option is for private keys as well. By default private keys
5715 are binary encoded and public keys PEM encoded. Silly HEX
5716 encoding were removed.
5718 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5719 function to create fingerprints.
5721 * Fixed a bug in SHA1; does not change the original data anymore.
5723 * Partly implemented INFO command on client and server side.
5724 Fixed CLEAR command. Changes to SERVER command; show current
5725 server(s) when giving command without arguments. Added
5726 VERSION command to client.
5728 * Added check to server that unregistered connections cannot
5729 execute commands (unless it is specificly allowed).
5731 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Fixed screen refresh.
5735 * Fixed channel joining bug from client. On some circumstances
5736 client tried to join to a channel it had already joined.
5738 * Added public key verification process into client's protocol.c.
5739 The client now verifies the public key from user and saves
5740 it into ~./silc/serverkeys/ directory.
5742 Added into: clientutil.[ch]: silc_client_verify_server_key.
5744 * Changed SKE protocol's silc_ske_initiator_finish function
5745 to accept callback function that verifies the received public
5746 key. Removed old silc_ske_verify_public_key function.
5748 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5751 silc_pkcs_private_key[_data]_set.
5753 * Made the password and public authentication more cleaner in
5754 server's protocol.c.
5756 * Removed historic and obsolete protocol `channel_auth' from
5757 both client and server.
5759 * Removed wrong way of sending command status messages from
5760 server to client in server's command.c. The old way violated
5761 protocol specification.
5763 Changes to silccore/silccommand.[ch]: removed
5764 silc_command_encode_status_payload -> not needed anymore,
5765 changed silc_command_encode_payload_va to accept extra
5766 argument on variable argument list. The argument type must
5767 now be provided to the function. Also, added new function:
5768 silc_command_encode_reply_payload_va which is same as
5769 normal command_encode_payload_va except command status type
5770 is provided as extra argument.
5772 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added ~./silc directory handling. The directory includes the
5775 public and private keys for the client.
5777 Added silc_client_check_silc_dir, silc_client_create_identifier
5778 and silc_client_load_keys.
5780 * Implemented SILC protocol compliant public key. Added public
5781 and private key saving to and loading from files.
5783 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5784 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5785 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5786 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5787 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5789 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5790 silc_pkcs_load_[public/private]_key.
5792 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Added silc_server_get_route (route.[ch]) to get connection
5795 data for the fastest route for given ID.
5797 * Implemented INVITE command on client and server. The command
5798 were re-defined in the SILC Protocol Specification and the
5799 implementation now complies with the specification.
5801 * Implemented PING command on client and server.
5803 * Implemented NAMES command on client and server. The server side
5804 supports currently only normal server not router server yet.
5805 Some changes to NAMES definition in SILC protocol specification.
5807 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Implemented LEAVE command on client and server.
5811 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5812 again. This change was made to the protocol as well. Server
5813 should not violate the protocol specification anymore.
5815 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5818 was tested. SOCKS4 was not but should work anyway.
