43 during SERVER_SIGNOFF, but invalidate it. This way we
44 preserve the WHOWAS info for the client. Affected file
47 * Fixed SERVER_SIGNOFF notify handling in the server. The
48 server is now able to process incoming SERVER_SIGNOFF notify
49 for a server that it doesn't even know about. It will remove
50 the clients provided in the notify. Affected file
51 silcd/packet_receive.c.

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

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

226 * Redefined the SILC packet header to include the padding
227 length. Affected file lib/silccore/silcpacket.[ch].
229 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
230 length for maximum padding up to 128 bytes). Affected
231 file lib/silccore/silcpacket.h.

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

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

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

504 entry always, not just when the command is coming from client.
505 Affected file silcd/command.c.
507 * Added new function silc_server_packet_queue_purge to purge the
508 outgoing data queue to the network. After the function returns
509 it is guaranteed that the outgoing packet queue is empty.
510 Affected file silcd/packet_send.[ch].
512 * Purge the outgoing packet queue in the rekey protocol's final
513 callback to assure that all rekey packets go to the network
514 before quitting the protocol. Affected file silcd/server.c.
516 * Added silc_client_packet_queue_parse as similar function as
517 in server to the client library. The affected file is
518 lib/silcclient/client.c.
520 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
522 * Splitted silcd/server.c and created silcd/server_util.[ch]
523 for utility functions.
525 * Added new socket flag SILC_SF_DISABLED to indicate that the
526 connection is open but nothing can be sent to or received from
527 the connection. Affected file lib/silcutil/silsockconn.[ch].
528 The checking for disabled socket is checked in the low level
529 silc_socket_write and silc_socket_read functions.
531 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
533 * Allow only nicknames and channel names that fits into the
534 7-bit unsigned char ASCII set. Affected file silcd/command.c.
536 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
538 * When processing JOIN command reply in server check that if
539 the channel exists in our global list we'll move it the local
540 list. Affected file silcd/command_reply.c.
542 * Fixed the check whether client is joined on the channel already
543 in JOIN command. Affected file lib/silcclient/command.c.
545 * Fixed the JOIN command reply to check whether the channel
546 already exists. Affected file lib/silcclient/command_reply.c.
548 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
550 * Added silc_ske_status_string to map the SKE error numbers
551 to readable strings. The affected files are
552 lib/silcske/silcske[_status].[ch].
554 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
556 * Do not show the private channels on the WHOIS channel list
557 as it is not allowed by the protocol. The affected file is
560 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
562 * Assure that the packet length digged from the actual packet
563 is something sensible in the silc_packet_decrypt_rest_special
564 in lib/silccrypt/silcpacket.c.
566 * Free and NULL the allocated pointer in silc_hmac_alloc if
567 the HMAC allocation fails. The affected file is
568 lib/silccrypt/silchmac.c.
570 * Print the selected security properties to the log files in
571 the server. Affected file silcd/protocol.c.
573 * Add SKE's reference counter even if calling the completion
574 callback manually. Otherwise it goes negative, although it
575 does not cause any problems. The affected file is
576 lib/silcske/silcske.c.
578 * Remove the client entry with short timeout after giving the
579 KILL command. Affected file lib/silcclient/command.c.
581 * Fixed to send error reply in WHOIS and IDENTIFY commands in
582 case all found clients are already disconnected (WHOWAS would
583 found them) in the server. Affected file silcd/command.c.
585 * Update the last_receive (time of last data received) to be
586 updated only when received private or channel message so that
587 the idle time showed in WHOIS makes more sense.
589 * Added boolean field `valid' in to the SilcClientEntry in the
590 client library to indicate whether the entry is valid or not.
591 This fixes the nickname change bug on channel when changing
592 the nickname to be same than the old (like nick to Nick) the
593 nickname formatter doesn't set the new nick anymore to Nick@host.
594 Affected file lib/silcclient/idlist.[ch].
596 * Now actually fixed the nickname changing on disconnection.
597 Added new function silc_change_nick to the Irssi SILC Client.
598 Affected file irssi/src/silc/core/client_ops.c,
599 irssi/src/silc/core/silc-nicklist.[ch].
601 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
603 * Check that the public key exists in the GETKEY command before
604 trying to encode it. Affected file silcd/command.c.
606 * Print some notifications on received public keys with GETKEY
607 command in the Irssi SILC Client. Affected files are
608 irssi/src/fe-common/silc/module-formats.[ch],
609 irssi/src/silc/core/client_ops.c.
611 * Use IDENTIFY command to resolve the server information in the
612 GETKEY command instead of INFO command. Affected file
613 lib/silcclient/command.c.
615 * All command reply functions in the client library now calls
616 the pending command reply callbacks even if an error has
617 occurred. The server has done this a long time and now it was
618 time to move the client library to this as well. Now all
619 errors can be delivered back to the pending command reply
620 callbacks if necessary. Affected files are
621 lib/silcclient/command[_reply].[ch].
623 * Change the nickname on disconnection back to the username
624 because in reconnect the server will enforce it to it anyway.
625 Affected file irssi/src/silc/core/silc-servers.c.
627 * Fixed a config file parsing bug in the Irssi SILC client.
628 Affected file irssi/src/silc/core/clientconfig.c.
630 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
632 * When printing the channel mode on JOIN, verify that the
633 channel key and channel's HMAC are valid. Affected file
634 irssi/src/silc/core/client_ops.c.
636 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
638 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
639 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
640 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
642 * Removed channel key rekey task deleting from the function
643 silc_server_save_channel_key. Affected file silcd/server.c.
644 Added explicit timeout task context instead that is used to
645 delete the task if we are registering a new task before the
646 new task has elapsed.
648 * When channel key rekey occurs the client library now saves
649 the old channel key for a short period of time (10 seconds) and
650 is able to use it in case some is still sending channel
651 messages encrypted with the old key after the rekey. Affected
652 file lib/silcclient/[idlist.h|client_channel.c].
654 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
656 * Added check to the silc_server_new_id_real to not accept
657 new ID if it is the sender's own ID. Affected file is
658 silcd/packet_receive.c.
660 * Assure that we do not announce ourself or the one we've
661 sending our announcements when we're router and are announcing
662 servers to our primary router. Affected file silcd/server.c.
664 * Fixed silc_server_command_identify_check_client to assemble
665 correct WHOIS packet. It send corrupted WHOIS packet and
666 caused problem with router to router connections. Affected
667 file silcd/command.c.
669 Fixed also silc_server_command_whois_check the same way
670 as for the IDENTIFY command.
672 * Added new SilcIDListStatus to the server in the SilcIDListData
673 structure. The status now includes the current status of
674 the entry (like registered, resolved etc.). Affected file
675 silcd/idlist.[ch]. Defined a bunch of different status types
676 as well. This replaced the old boolean registered field as well.
678 Added resolve_cmd_ident field to the SilcClientEntry structure
679 too so that if the entry is for example being resolved so
680 another command may attach to the same pending command reply
681 without requiring to resolve the same entry again. This concept
682 should optimize the WHOIS and the IDENTIFY resolving under
683 heavy load by taking away unnecessary resolving for entries
684 that are being resolved already.
686 Added support for adding multiple pending commands for one
687 command idenfier. Affected file silcd/command[_reply].[ch].
689 * Fixed WHOIS and IDENTIFY save to remove the cache entry
690 before deleting the data. Otherwise the hash table will have
691 freed data in comparison functions. Affected file is
692 silcd/command_reply.c.
694 * Fixed silc_idlist_replace_client_id to add the new entry to
695 the cache with NULL nickname. Otherwise there will be invalid
696 memory as the nickname after the nickname is freed. Affected
697 file silcd/packet_receive.c.
699 * Fixed the silc_idlist_get_clients_by_hash. The entries was
700 saved into wrong slots because the previous number of entries
701 was not taken into account. Affected file silcd/idlist.c.
702 Fixed same thing in silc_idlist_get_clients_by_nickname too.
704 * If we are router and we receive JOIN notify to a channel that
705 does not have any users then notified client is marked as the
706 channel founder, as it is it. The affected file is
707 silcd/packet_receive.c
709 * Added to the extended hash table API's table_del_*ext functions
710 the destructor as argument too, so that the caller can decide
711 which destructor to use or whether to use destructor at all.
712 Affected file lib/silcutil/silchashtable.[ch].
714 * Fixed ID Cache purging. It actually deleted the entries from
715 the hash table after the data was freed. The hash table ended
716 up comparing freed memory. The affected file is
717 lib/silccore/silcidcache.c.
719 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
721 * Fixed Irssi SILC client's KILL command's HELP syntax.
723 * The USERS command now resolves the detailed user information
724 if the userinfo field is missing. Affected file is
725 lib/silcclient/command_reply.c.
727 * Do not print error in silc_file_read if the read file does
728 not exist. Just silently return NULL. Affected file is
729 lib/silcutil/silcutil.c.
731 * Fixed the silc_log_output to not wine about NULL filename
732 and to not create some bogus " " filename. Affected file is
733 lib/silcutil/silclog.c.
735 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
737 * Fixed various printing bugs on the user interface in the
738 Irssi SILC Client. Minor changes that were forgotten from
741 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
743 * Fixed the configure.in.pre and the compilation and distribution
744 environment to support the new autoconf 2.52. That version is
745 now required to compile the CVS trunk.
747 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
749 * Renamed function silc_parse_nickname to silc_parse_userfqdn
750 to generally parse user@fqdn format strings. Affected file
751 lib/silcutil/silcutil.c.
753 * Added nickname_format and nickname_force_format fields to the
754 SilcClientParams structure. The first one defines the format
755 for the nicknames that the library will enforce if the receives
756 multiple same nicknames. The second one is boolean value and
757 can be used to force the library to always enforce the format
758 to the nicknames regardles whether there are multiple nicknames
759 or not. This configurable formatting was employed to flexibly
760 support accessing multiple nicknames from the user interface.
761 The userinterface can now set the nicknames to what ever format
762 they prefer. Affected file lib/silcclient/silcapi.h.
764 Added function silc_client_nickname_format to the file
765 lib/silcclient/idlist.c. It performs the nickname formatting.
767 Added new field `hostname´ to the SilcClientEntry context.
768 It holds the hostname of the client. Affected file is
769 lib/silcclient/idlist.h.
771 * Irssi SILC Client sets the nicknames in nick@hostn format.
772 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
773 irssi/src/silc/core/silc-core.c.
775 The WHOIS printing now also shows both the real nickname and
776 the formatted nickname so that user knows how to access the
777 user if there are multiple same nicknames cached. Affected
778 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
779 printing formatting too to take the hostname now as a separate
780 argument. The Affected file is
781 irssi/src/fe-common/silc/modules-formats.[ch].
783 * Changed the silc_client_get_clients_local to accept the formatted
784 nickname as argument. It accepts the real nickname too but the
785 formatted nickname can be used to find the true entry from
786 multiple entries. Affected file lib/silcclient/silcapi.h and
787 lib/silcclient/idlist.c.
789 * Added nickname_format_parse field to the SilcClientParams.
790 It is a callback function provided by the application to parse
791 the nickname out of the formatted nickname string. The library
792 calls it to get the nickname from the formatted string. Since
793 the application generally knows better the format of the nickname
794 string it parses it instead of the library, even though library
795 encodes the formatted string. If the callback function is not
796 provided then the library will use the string as is. The
797 affected file is lib/silcclient/silcapi.h.
799 * All the nickname strings passed to the client library in
800 commands are now expected to be formatted nickname strings.
801 If the command does not support the formatted nickname string
802 it will assume that the sent string is the actual nickname.
803 Affected file lib/silcclient/command.c.
805 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Added public key authentication support to OPER and SILCOPER
808 commands in the client library. Affected file is
809 lib/silcclient/command.c.
811 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Changed the get_auth_methdod client operation to be asynchronous.
814 It can be async if the application resolves the authentication
815 method from the server during the negotiation. Added new
816 SilcGetAuthMeth completion callback that the application will
817 call after resolving the authentication method.
819 Added function silc_client_request_authentication_method that
820 the application can use to resolve the authentication method
821 from the server. Added also SilcConnectionAuthRequest callback
822 that the library will call after the server has replied. The
823 application can call this function if it does not know the
824 current authentication method.
826 Affected files are lib/silcclient/client.c and
827 lib/silcclient/silcapi.h.
829 * The Irssi SILC client now automatically resolves the authentication
830 method incase any configuration information is not present (and
831 currently there never is). The affected file is
832 irssi/src/silc/core/client_ops.c.
834 * Fixed public key authentication from the client library.
835 Affected file lib/silcclient/protocol.c. Changed also the
836 protocol specification about the public key authentication in
837 the connection authentication protocol. The actual data to be
838 signed is now computed with a hash function before signing.
840 * Fixed the public key authentication from the server as well.
841 Affected file silcd/protocol.c.
843 * Removed the mlock()'s from the memory allocation routines.
844 Affected file lib/silcutil/silcmemory.c. The ./configure does
845 not check anymore for the mlock(). Affected file is
848 * Fixed USERS command in server to allow the execution of the
849 command for private and secret channels if the client sending
850 the command is on the channel. Affected file silcd/command.c.
852 * Fixed silc_client_get_clients_local to return the clients
853 count correctly. It could return wrong value. Affected file
854 lib/silcclient/idlist.c.
856 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
859 types. The assembler optimizations seemed not to like 64-bit
860 data types. The assmebler optimizations thus are now enabled
861 also for BSD systems as opposed to only enable them for Linux.
863 * Do not check for threads at all on BSD systems. Affected
864 file configure.in.pre.
866 * Removed -n and -h options from the Irssi SILC Client since
867 they are not used in silc.
869 * Fixed the prime generation to assure that the first digit
870 of the generated random number is not zero since our conversion
871 routines does not like number strings that starts with zero
872 digit. If zero digit is seen the random number is regenerated.
873 This caused some corrupted RSA keys when the zero first digit
874 was met. Affected file lib/silcmath/silcprimegen.c.
876 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
878 * Fixed WIN32 configuration in the ./configure script.
879 Fixed to include xti.h on environments that has it.
880 Patches by Carsten Ilchmann and andrew.
882 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
884 * Changed the silc_id_create_client_id to be collision
885 resistant. It is now assured that there cannot be created
886 two same client ID's. I suspect that some weird bugs in
887 the server were actually caused by duplicate Client IDs.
888 Affected file silcd/serverid.[ch]. A router receiving
889 new ID now also assures and informs the sending server
890 if the ID caused collision.
892 * Changed the silc_id_create_channel_id to also assure that
893 there are no collisions.
895 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Statement about ignoring the Mutual Authentication flag when
898 performing rekey with PFS was a bit misleading. It is ignored
899 if it was set in the initial negotiation, it cannot be even
900 set in the rekey. Fixed in the ke-auth draft. Started the
901 new versions of the protocol drafts in the doc/.
903 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
905 * Fixed a bug in silc_client_command_identify_save when saving
906 new channel information. The channel name was no duplicated
907 and caused crash on exit. Affected file is
908 lib/silcclient/command_reply.c.
910 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
912 * Fixed the getkey command handling in the server. Send just
913 empty OK reply to the sender if the key could not be fetched
914 (but everything else was ok, like the key just was not available).
915 Changed the public key parameter to optional in the protocol
916 specs so that empty OK reply can be sent. Affected file
919 Added a message to Irssi SILC client to tell to user if the
920 server did not return a public key.
922 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
924 * Fixed a channel key regeneration bug. It registered new
925 timeout tasks exponentially until all system resources were
926 used. Affected file silcd/server.c.
928 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
930 * Added the SILC Document generator to the scripts/silcdoc.
931 It can be used to generate the Toolkit Reference Manual out
932 of the source tree. Internally it will also use the RoboDoc
933 generator now imported in util/robodoc.
935 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
937 * Added couple of return's in rekey protocol if error orccurred
938 during the protocol. The execution must be terminated.
939 Affected file silcd/protocol.c. Also, terminate the protocol
942 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
944 * The client's Client ID was created initally from the wrong
945 nickname (it could have been in format nick@host) in the
946 silc_server_new_client. Affected file silcd/packet_receive.c
948 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Added some SILC_LOG_ERROR's to various error conditions
951 if client could not be added to ID cache. Affected files
952 silcd/packet_receive.c and silcd/server.c.
954 * When client's sock->user_data is freed, NULL also the
955 client->router and client->connection pointers. Added check
956 for these pointers being NULL to various places around the
957 code. Affected file silcd/server.c.
959 * Added client->data.registered == TRUE checks to various
960 places around the code to assure that unregistered client's
961 are not handled when it is not allowed. Affected file
964 * Added `bool registered' fields to all
965 silc_idlist_[server|client]_get_* routines to indicate whether
966 the fetched client needs to be registered or not. Affected
967 file silcd/idlist.[ch].
969 * Add your own entry as registered to the ID cache in the
970 server. Affected file server.c.
972 * Fixed a bug in silc_server_new_server. The SilcServer was
973 set as the new server's context instead of SilcServerEntry.
974 This naturally caused some weird bugs.
976 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
978 * Do not delete the channel rekey task when adding it
979 for in silc_server_create_channel_key.
981 * Changed the silc_server_create_channel_key to return
982 TRUE or FALSE to indicate the success of the channel key
985 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
987 * Fixed MSVC++ project files and added missing files to
988 Makefiles under win32/.
990 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
992 * Do not add TCP_NODELAY flag if the operating system
993 does not have it defined. Affected files are
994 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
996 * Fixed buffer overflow from Irssi SILC Client. Affected
997 file irssi/src/fe-common/core/themes.c.
999 * Fixed double free in client library in the file
1000 lib/silcclient/client.c when disconnecting from server.
1002 * Applied double free patch from cras to Irssi SILC client.
1003 Affected files irssi/src/core/[modules/expandos].c
1005 * Fixed the disconnection handling to Irssi SILC Client.
1006 The application must call silc_client_close_connection
1007 in ops->connect client operation in case of failure of
1008 the connection. Affected file is
1009 irssi/src/silc/core/client_ops.c.
1011 * Do not set sock->protocol to NULL in the function
1012 silc_client_close_connection after executing the protocol's
1013 final callback since the sock might not be valid anymore.
1014 Affected file lib/silcclient/client.c.
1016 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Do not enable SILC_THREADS if the linking with libpthread
1019 did not happen. Affected file configure.in.pre.
1021 * Added notion to protocol specification that server must
1022 verify the sent authentication payload with CMODE when
1023 setting the channel founder key. Implemented it to the
1024 server. Affected file silcd/command.c.
1026 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Added _EXTRA_DIST SILC distribution variable to the
1029 distributions file. It is used to conditionally add extra
1030 files or directories to the specific distribution. Affected
1031 files ./prepare, Makefile.am.pre and distributions.
1033 Removed the `_' from the start of the distribution names.
1036 * Added README.WIN32 for instructions to compile the Toolkit
1039 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Fixed a double free in disconnection in the server. Affected
1042 file is silcd/server.c.
1044 * Fixed the lib/silcske/groups.c to work now also with GMP
1045 MP library. The string conversion did not work when using
1046 specific base and the base is indicated in the string as well.
1048 * Created win32/ directory which now includes MSVC++ specific
1049 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1050 It will appear only in the toolkit distribution
1052 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Changed the key material distribution function in case when
1055 the hash output is too short. The data is now concatenated
1056 a bit differently than it used to. Made the change to the
1057 SKE protocol specification.
1059 * Added better GMP detection to configure.in.pre. A patch
1062 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Fixed a minor bug in SKE that might cause some problem on
1065 some platforms. Affected file lib/silcske/silcske.c.
1067 * Added the cookie checking for initiator in the SKE. It checks
1068 that the responder returns the sent cookie unmodified. The
1069 affected file is lib/silcske/silcske.c. Added new SKE
1070 error type INVALID_COOKIE that can be sent during the
1071 negotiation. Fixed some memory leaks as well.
1073 * Added the "invalid cookie" error message to Irssi SILC client's
1076 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1078 * Added `task_max' field to the SilcClientParams to indicate
1079 the maximum tasks the scheduler can handle. If set to zero,
1080 default values are used. Affected file lib/silcclient/silcapi.h.
1082 * Fixed memory leaks in silc_client_close_connection. Affected
1083 file lib/silcclient/client.c.
1085 * Added silc_client_del_client_entry to client library to free
1086 all memory of given client entry. Affected file is
1087 lib/silcclient/idlist.[ch].
1089 * Added new functions silc_client_del_channel and
1090 silc_client_del_server to delete channel and server entries.
1091 Affected file lib/silcclient/[silcapi.h/idlist.c].
1093 * Removed silc_client_del_client_by_id from silcapi.h.
1095 * Fixed the INFO command to return the server's own info
1096 correctly when querying by Server ID. Affected file is
1099 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1101 * Removed the non-blocking settings in WIN32 code in the
1102 silc_sock_[read/write] and added SleepEx instead. Affected
1103 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1104 of input data is now checked with FIONREAD and ioctlsocket.
1106 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1108 * Call silc_schedule_task_del_by_context in the
1109 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1110 Affected file lib/silccore/silcprotocol.c.
1112 * Call silc_protocol_cancel for active protocols in the
1113 silc_server_close_connection if the funtion
1114 silc_server_free_sock_user_data has not been called.
1115 Affected file silcd/server.c.
1117 * Generic tasks cannot be deleted using the del_by_fd
1118 task deleting function since generic tasks does not match
1119 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1121 * Added a notion to SILCOPER help file that the SILCOPER works
1122 only on router server, not on normal server.
1124 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1126 * Added for WIN32 support for the new scheduler as well.
1127 Affected file lib/silcutil/win32/silcwin32schedule.c.
1129 * Fixed the SHA1 implementation to work on various platforms.
1131 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1133 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1134 API. It is part of the scheduler now. Everything else is
1135 as previously but some functions has changed their names.
1136 Checkout the lib/silcutil/silcschedule.h for the interface.
1137 Updated all applications to use the new interface. Affected
1138 files are lib/silcutil/silcschedule.[ch].
1140 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Found a bug in the SKE implementation. The HASH value,
1143 specified by the protocol, was not computed correctly. The
1144 public key of the responder was not added to the computation
1145 even though it is mandatory. Affected file lib/silcske/silcske.c.
1146 This unfortunately causes incompatibilities with older
1147 clients and servers.
1149 * Added WIN32 specific network init and uninit functions:
1150 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1151 the Winsock2. Affected file lib/silcutil/silcnet.h and
1152 lib/silcutil/win32/silcwin32net.c.
1154 * Set the socket always to nonblocking mode on WIN32 after
1155 reading data or writing data. Affected file is
1156 lib/silcutil/win32/silcwin32sockconn.c.
1158 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1160 * Fixed various compilation problems under WIN32. Affected
1161 files lib/silcutil/win32/silcwin32thread.c and
1162 lib/silcutil/win32/silcwin32schedule.c.
1164 * Removed all _internal.h #includes from public header
1165 files. Internal headers must never be included from
1168 Removed also the lib/silcske/payload_internal.h file.
1170 * All include files that may be needed (public and some others
1171 included by the public headers) by application developers are
1172 now copied to the ./includes directory. It does not copy any
1173 internal headers. Affected file Makefile.defines.pre and all
1174 Makefile.am's under lib/ and subdirs.
1176 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1178 * Do not change the ~/.silc directory's permissions automatically.
1179 Affected file irssi/src/silc/core/clientutil.c.
1181 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1183 * Do not cancel the protocol in silc_server_close_connection
1184 it might cause recursion. Now cancelled in the function
1185 silc_server_free_sock_user_data. Affected file silcd/server.c.
1187 * Fixed the silc_server_remove_clients_by_server to regenerate
1188 the channel keys correctly finally. Added also new function
1189 silc_server_remove_clients_channels to actually do it.
1190 Affected file silcd/server.c.
1192 * Fixed the silc_server_new_channel to not crash by giving
1193 wrong router to the new channel. Affected file is
1194 silcd/packet_receive.c.
1196 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1198 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1199 which is given as argument to the silc_client_alloc now.
1200 It can be used to configure the client and set various parameters
1201 that affect the function of the client.
1203 * The USERS command in server did not check whether the channel
1204 is private or secret. Affected file silcd/command.c.
1206 * Added new argument to the USERS command in protocol specification.
1207 The USERS command now can take the channel name as argument
1208 as well. Added support for this in client and server and
1209 updated the protocol specs.
1211 * Completed the GETKEY command in client. It can be now used
1212 to fetch also servers public key not only some clients.
1213 Affected files lib/silcclient/command[_reply].c.
1215 * Added silc_client_get_server to return server entry by the
1216 server name. Affected files lib/silcclient/silcapi.h and
1219 * Redefined the IDENTIFY command in protocol specification to be
1220 more generic. It now can be used to query information about
1221 any entity in the SILC Network, including clients, servers and
1222 channels. The query may be based either the entity's name
1223 or the ID. Added support for this in both client and server.
1225 Affected files silcd/command.c and lib/silcclient/command.c
1226 and command_reply.c.
1228 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1229 the _from_client and _from_server functions. Affected file
1232 * Added silc_client_get_channel_by_id_resolve to the file
1233 lib/silcclient/silcapi.h to resolve channel information by
1234 its ID. Added also silc_client_get_channel_by_id that
1235 does not resolve it from the server.
1237 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1239 * Added SilcServerEntry context into the client library
1240 to represent one server. The INFO command now allocates
1241 these to save the resolved server info. For now on the
1242 client library will also keep information about servers,
1243 connected and resolved with INFO.
1245 The INFO command now allocates the SilcServerEntry context
1246 and saves the server info there. The COMMAND_REPLY in
1247 the INFO now returns the parameters to application in
1248 same order as defined in the protocol specification.
1250 The entries are cached in the client->server_cache.
1252 * The INFO command is now issued after received the Client ID
1253 from the server. Affected file lib/silcclient/client.c.
1255 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1256 to the application as the mode changer might be server.
1257 It is guaranteed that NULL is not returned anymore to the
1258 application. Affected file lib/silcclient/client_notify.c.
1260 The ID Type is now also passed to the application so that
1261 it can check whether the returned entry is SilcClientEntry
1264 Added new function silc_client_get_server_by_id to return
1265 the server entry by ID. Affected files are the
1266 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1268 * Do not create the channel in the Irssi SILC Client when issuing
1269 the JOIN command but when received the sucessful JOIN command
1270 reply. Otherwise the channel might get created even though we
1271 could not join it. The Affected file is
1272 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1274 * Fixed a channel joining bug in router. The router must also
1275 check the channel modes, invite and ban lists etc. when serving
1276 the JOIN command sent by normal server. Affected file is
1277 silcd/command.c. The router now resolves the client's
1278 information from the server who sent the JOIN command if it
1279 does not know it, and processes the JOIN command only after
1282 * Changed the SilcCommandCb to take new argument; void *context2.
1283 Affected file lib/silccore/silccommand.h
1285 The second argument in the command callbacks in the server now
1286 includes the SilcServerCommandReplyContext if the command was
1287 called as pending command callback from the command reply.
1288 Otherwise it is NULL. When called as pending the status of the
1289 command reply will be checked and if it was erronous the
1290 error will be sent to the original sender of the command.
1291 This way the client always receives the error messages even
1292 though the server was actually the one who received the error
1293 when it resent the command to router, for example. Affected
1294 files silcd/command[_reply].[ch].
1296 * Fixed sending WHOWAS command's error message to client if
1297 the requested client could not be found. It was missing.
1300 * Changed the CMODE and CUMODE commands reply arguments in the
1301 protocol specification. The Channel ID is now sent in both
1302 of the commands to identify the channel. Implemented this
1303 new feature to the client and server. Affected files
1304 lib/silcclient/command_reply.c and silcd/command.c.
1306 * Made better checks for invite and ban lists in the JOIN
1307 command in server. Affected file silcd/command.c.
1309 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1311 * The server now performs the incoming host IP/DNS lookup
1312 using the silc_socket_host_lookup and thus does not block
1313 the server anymore. Affected file silcd/server.c.
1315 * Completed the multi-thread support for SILC Scheduler in
1316 the lib/silcutil/silcschedule.c.
1318 * Fixed the configure.in.pre to detect the pthread correctly
1321 * Fixed a deadlock in silc_task_queue_wakeup in the file
1322 lib/silcutil/silctask.c.
1324 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Added new function silc_schedule_wakeup that is used in
1327 multi-threaded environment to wakeup the main thread's
1328 schduler. It needs to be used when a thread adds a new task
1329 or removes a task from task queues. After waking up, the
1330 scheduler will detect the task queue changes. If threads
1331 support is not compiled in this function has no effect.
1332 Implemented the wakeup mechanism to both Unix and WIN32
1333 systems. Affected files are lib/silcutil/silcschedule.[ch],
1334 lib/silcutil/unix/silcunixschedule.c and the
1335 lib/silcutil/win32/silcwin32schedule.c.
1337 * Added new function silc_task_queue_wakeup to wakeup the
1338 scheduler by the specified task queue. Affected file
1339 lib/silcutil/silctask.[ch].
1341 * The silc_socket_host_lookup_start now wakes up the scheduler
1342 after adding the timeout task. Affected file is
1343 lib/silcutil/silcsockconn.c.
1345 * The silc_socket_host_lookup is synchronous now if the threads
1346 support is not compiled in. However, the callback is still
1347 called asyncronously through the scheduler, anyway. Affected
1348 file lib/silcutil/silcsockconn.c.
1350 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Added new function silc_socket_host_lookup to perform
1353 asynchronous IP and FQDN lookups for the socket connection.
1354 Affected files lib/silcutil/silcsockconn.[ch].
1356 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1359 that may or may not compile the mutex support in.
1361 Changed the silc_mutex_alloc interface. It allocates the
1362 mutex now to the sent pointer and returns TRUE or FALSE.
1364 Affected file lib/silcutil/silcmutex.h.
1366 * Wrote the SILC Task Queue interface to support multi-threads.
1367 Affected file lib/silcutil/silctask.[ch].
1369 * Wrote the SILC Scheduler to support multi-threads. Affected
1370 file lib/silcutil/silcschedule.c.
1372 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1374 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1375 in lib/silcutil/win32/.
1377 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1379 * Defined SILC Mutex API and SILC Thread API and implemented
1380 them for Unix. Affected files are
1381 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1382 lib/silcutil/unix/silcunixmutex.c and
1383 lib/silcutil/unix/silcunixthread.c.
1385 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Fixed the silc_server_remove_clients_by_server's channel
1388 key re-generation. The hash table handling was incorrect
1389 and would not work with many channels. Affected file is
1392 * Fixed some memory leaks around the server code.
1394 * Rewrote the silc_server_get_users_on_channel to support IPv6
1395 based Client ID's. Affected file silcd/server.c.
1397 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1398 specification. However, a separate document must be written
1399 to define the detailed signing procedure and the payload
1400 associated with the flag. Defined the flag to the
1401 lib/silccore/silcchannel.h as well.
1403 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Changed the dynamic tables to static size tables in the
1406 lib/silccrypt/silchmac.c.
1408 * Removed GCC dependencies from the code. A patch by cras.
1410 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * Do not show the error "Error receiving packet bla bla"
1413 in server if it really was not an error (-2 means that reading
1414 is pending). Affected file silcd/server.c.
1416 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1418 * Fixed a possible crash in silc_server_remove_clients_by_server
1419 in silcd/server.c. Fixed there also some memory leaks.
1421 * Fixed the silc_idlist_replace_client_id. It could replace
1422 wrong key in the hash table. Affected file silcd/idlist.c.
1424 * Do not check whether there are global users on the channel
1425 if the channel->global_users is FALSE. Affected functions
1426 silc_server_remove_from_one_channel and
1427 silc_server_remove_from_channels in silcd/server.c. Also,
1428 do not check if the removed client is local as we can be
1429 sure that global client was not removed from the channel
1430 and checking for global users is not needed.
1432 * The silc_server_remove_clients_by_server now re-generates
1433 the channel keys correctly for those channels that had
1434 clients removed from them. Affected file silcd/server.c.
1436 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Found the reason of random crashes in the server. We weren't
1439 ignoring the SIGPIPE signal (which can be sent in write())
1440 and it crashed the server. Affected file silcd/silcd.c.
1442 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Assure that sock->user_data is not NULL in the function
1445 silc_server_packet_send in silcd/packet_send.c.
1447 * Disconnect the remote connection if it could not be added
1448 to any ID lists in the server. The affected file is
1451 * Check in silc_server_packet_send[_real/dest] that the
1452 socket is not disconnecting and ignore the data if it is.
1453 Affected file silcd/packet_send.c.
1455 * Define inline to __inline on native WIN32 compilation.
1456 Affected file includes/silcwin32.h.
1458 * Added some explicit type casts for inline code since MSVC
1459 require them. Affected files lib/silcutil/silcbuffer.h,
1460 lib/trq/silcdlist.h and lib/trq/silclist.h.
1462 * Print warning in log files from now on if the packet
1463 decryption fails. Affected file silcd/server.c.
1465 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1467 * Changed the `say' client operation's interface to accept
1468 new `type' argument to indicate the type of the message sent
1469 by the library. The application may filter the library's
1470 messages according the type. The affected file is the
1471 lib/silcclient/silcapi.h.
1473 * Added two new functions to lib/silcclient/silcapi.h:
1474 silc_client_del_client and silc_client_del_client_by_id.
1475 Affected file lib/silcclient/idlist.c.
1477 * Moved the clientincludes.h from includes/ to silc/ and
1478 serverincludes.h from includes/ to silcd/.
1480 * The modes for the CMODE and CUMODE are now passed as
1481 uint32 for application with COMMAND_REPLY. The affected
1482 file is lib/silcclient/command_reply.c.
1484 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1486 * /WHOIS without arguments shows client's own information.
1487 Affected file lib/silcclient/command.c.
1489 * Changed PING to not accept any arguments. The specs
1490 says that client can ping only the connected server so
1491 requiring an argument is not needed. Affected file is
1492 lib/silcclient/command.c.
1494 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Fixed a fatal bug in private message sending and reception
1497 encryption and decryption when using private message keys.
1498 The implementation was incorrect and did not follow the
1499 specification. It causd that some of the message were
1500 lost since it did not use the sending and receiving keys
1501 as the protocol suggests. This has been fixed and will cause
1502 incompatibilities with older clients when sending private
1503 message encrypted with private message keys. Affected files
1504 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1505 and various other in Irssi SILC Client.
1507 Added `responder' boolean argument to the functions
1508 silc_client_add_private_message_key[_ske] to indicate when
1509 the key is added as responder or initiator of the key
1512 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Removed the silc_ske_check_version function and created
1515 a SilcSKECheckVersion callback. Added also a function
1516 silc_ske_set_callbacks that is now used to set all SKE
1517 callbacks. The callback functions are not given to
1518 the SKE functions anymore, but this function is used to
1521 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1523 * Added `silc_version' argument to the silc_client_alloc
1524 to define the version of the application for the library.
1525 The library will use the version string to compare it
1526 against the remote host's (usually a server) version
1527 string. Affected file lib/silcclient/silcapi.h
1529 * Added the KE protocol context to Key Agreement context
1530 in client library so that we can abort the SKE if it
1531 is in process when we get timeout. Affected file is
1532 lib/silcclient/client_keyagr.c.
1534 * Do not resolve the client ID forever if it returns in the
1535 first time that such client does not exist. This was done
1536 for example with private message. Affected file is
1537 lib/silcclient/client_prvmsg.c.
1539 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1541 * Do not add regex.h for WIN32. The affected file
1542 includes/silcincludes.h.
1544 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1545 not work yet 100%. It generates the DLL's automatically
1546 when compiling with --with-win32 under cygwin.
1548 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1550 * lib/contrib/regex.c is not compiled on WIN32.
1552 * Added silc_net_get_socket_opt function to the
1553 lib/silcutil/silcnet.h.
1555 * Added includes/silcwin32.h for WIN32 specific includes
1558 * Do not use ptime structure or any of the posix process
1559 functions on WIN32 in lib/silccrypt/silrng.c.
1561 * Added silc_gettimeofday to provide generic function
1562 for struct timeval on all platforms. Added the function
1563 to lib/silcutil/silcutil.h.
1565 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1568 library as they clearly belong there. As a plus side we
1569 can make the actual socket connection routines platform
1572 Added also new generic function silc_socket_read and
1573 silc_socket_write (that used to be silc_packet_[read/write].
1574 The implementation of these are platform specific.
1576 * Added WIN32 specific routines of silc_socket_[read/write]
1577 to lib/silcutil/win32/silcwin32sockconn.c.
1579 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1581 * Added preliminary support for native WIN32 compilation under
1582 cygwin (using the -mno-cygwin option for GCC) to the
1583 ./configure.in.pre. The --with-win32 now prepares the
1584 compilation for native WIN32.
1586 * Rewrote the SILC Scheduler interface in the file
1587 lib/silcutil/silcschedule.h. The scheduler is now context
1588 based and does not have anymore any global static scheduler.
1589 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1590 and created lib/silcutil/win32 directory for WIN32 based
1593 * Added Unix specific network routines to the
1594 lib/silcutil/unix/silcunixnet.c and the old
1595 lib/silcutil/silcnet.c includes now only generic routines.
1597 Added WIN32 specific network routines to the
1598 lib/silcutil/win32/silcwin32net.c.
1600 * Added Unix specific utility functions from the
1601 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1603 * Added WIN32 SILC Scheduler to the file
1604 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1607 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1609 * Do not handle JOIN notify in the server if the target client
1610 is not registered (idata->registered == FALSE). The affected
1611 file is silcd/packet_receive.c.
1613 * Update the nickrec->founder in event_cumode in the Irssi SILC
1614 client. Affected file irssi/src/silc/core/silc-channels.c.
1616 * Fixed the CUMODE_CHANGE notify handling in the server when
1617 server and router are announcing their clients on channels.
1618 Now the mode changes are saved and notified correctly. The
1619 affected file is /silcd/packet_receive.c.
1621 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1622 They really did not replace the cache entry in the ID Cache.
1623 Now they do that. Affected file silcd/idlist.c.
1625 * Fixed the KICK notify handling in the Irssi SILC client to
1626 update the channel records so that the kicked client does not
1627 appear to be on the channel. The affected file is
1628 irssi/src/silc/core/silc-channels.c.
1630 * Always update the conn->current_channel when executing command
1631 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1633 * Fixed the KILL notify handling in Irssi SILC client to remove
1634 the killed client on all channels.
1636 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1638 * Fixed the silc_parse_command_line to remove extra spaces
1639 from the start and end of the arguments. Affected file is
1640 lib/silcutil/silcutil.c.
1642 * Cancel and free any active protocol in the function
1643 silc_server_close_connection. Affected file silcd/server.c.
1645 * Cancel and free any active protocol in the function
1646 silc_client_close_connction. Affected file is
1647 lib/silcclient/client.c.
1649 * Do not execute the KILL command for clients that are in
1650 history (ie. they are not in the network). Affected file is
1653 * Fixed KILL notify handling, client does not crash anymore.
1654 Affected file irssi/src/silc/core/silc-channels.c.
1656 * Reduced the default packet buffer size from 2048 to 1024 in
1657 lib/silccore/silcpacket.c.
1659 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1660 counter to the SKE context that is incresed when the SKE library
1661 performs async operation outside the library. If the outside
1662 process frees the SKE context and FREED status will be set
1663 and the library will detect after the sync operation that the
1664 libary is freed. The affected files are
1665 lib/silcske/silcske[_status].[ch].
1667 * Resolve the client entry information in the function
1668 silc_client_channel_message to assure that NULL pointer is not
1669 passed as client entry to the application. */
1671 * Fixed the task timeout calculation to assure that there is
1672 never negative timeouts. The affected file is
1673 lib/silcutil/silcschedule.c.
1675 * Fixed the channel user mode notification sending in server.
1676 It was sent point-to-point to the router (or to server by router)
1677 but it needs to be destined to a channel. The routines now
1678 supports sending the channel user mode notifys to the channels
1679 when announcing clients and channels. Affected files are
1680 silcd/server.c and silcd/packet_receive.c.
1682 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1683 It did not actually replace the old channel entry in the cache.
1684 Affected file lib/silcclient/client_notify.c.
1686 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1688 * Fixed a possible crash in silc_packet_send_prepare. It now
1689 assures always that there is enough space in the buffer and
1690 at the tail area of the buffer (for MAC).
1692 Fixed the inbound buffer reallocation in silc_packet_read.
1693 It was old code and did not handle the reallocation correctly.
1696 The affected file is lib/silccore/silcpacket.c.
1698 * Fixed buffer overflow in silc_parse_nickname in the file
1699 lib/silcutil/silcutil.c.
1701 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1703 * make install generates new server keys only if there is not
1706 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1709 Added check that if the NOREPLY is set then we will not send
1710 the away message. This avoids infinite loop of away messages
1711 if both clients are away. The affected file is
1712 lib/silcclient/client_prvmsg.c.
1714 * Fixed client crash if /NICK was given without arguments.
1715 Affected file lib/silcclient/command.c.
1717 * Server does not send the invite list in INVITE command back
1718 to the client if the list was not altered. Added this notion
1719 to the protocol spec as well. Affected file silcd/command.c.
1721 Fixed possible crash in INVITE command by checking the
1722 value of silc_server_get_client_route command.
1724 * Fixed the INVITE notify type handling. The arguments are now
1725 taken in correct order and client does not crash. The affected
1726 file is irssi/src/silc/core/silc-channels.c.
1728 Removed the "Inviting xxx to channel" message from the
1729 client library away and let the application handle it.
1730 Affected file lib/silcclient/command.c. Added that message
1731 to Irssi SILC client's message formats.
1733 * Fixed CMODE command crash in client. It now checks the
1734 amount of arguments correctly and does not crash. The affected
1735 file is lib/silcclient/command.c.
1737 * Do not create new channel automatically in silc_channels_join
1738 but check whether the channel by that name already exists.
1739 Affected file irssi/silc/core/silc-channels.c.
1741 * Do not send the SERVER_SIGNOFF to router if the disconnected
1742 entity was the router. Affected file silcd/server.c.
1744 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1745 SILC client as it was missing from there.
1747 Added the handling of the KICK notify to the Irssi SILC client
1748 as it was missing. Added "you have been kicked" message to
1749 Irssi SILC client's message modules formats.
1751 Added the handing of the KILL notify to the Irssi SILC client
1752 as it was missing. Added the kill message module formats
1755 The affected file is irssi/src/silc/core/silc-channels.c.
1757 * The router did not save the channel mode the server announced.
1758 Affected file silcd/packet_receive.c.
1760 * Fixed a possible crash in INFO command in server. If the
1761 server did not provide the server info it crashed. Affected
1762 file silcd/command.c.
1764 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1766 * Fixed the GETKEY command in the server to check also the
1767 global list. Otherwise the GETKEY would not work correctly
1768 in normal SILC server. Affected file silcd/command.c.
1770 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Fixed GETKEY crash, it crashed if the command did not succseed.
1774 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1777 is now real and not just an macro interface to GMP.
1779 Removed the entire GMP from the source tree and imported new
1780 NSS MPI library instead. Reason for removing GMP is that it is
1781 extremely large and compiles extremely slow. The NSS MPI
1782 is only a few files and compiles in less than 10 seconds.
1783 The speed is also about the same as GMP. The MPI is imported
1784 to lib/silcmath/mpi.
1786 If the system has GMP installed we will still use the GMP.
1787 If it is not then the NSS MPI will be compiled.
1789 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1791 * Merged a long nickname (127 characters long) crash bugfix from
1792 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1794 * Merged a freed memory reference bugfix from Irssi CVS tree.
1795 Affected file irssi/src/core/commands.c.
1797 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Added the server's public key sving and verification to the
1800 server when performing the SKE. This was missing and the
1801 remote server's (or router's) public key was accepted without
1802 checking whether we have it previously or trust it at all.
1803 Affected file silcd/protocol.c.
1805 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1807 * Check in the silc_server_timeout_remote if protocol is active
1808 and make sure that the protocol's final callback is called so
1809 that all memory if freed. Affected file silcd/server.c.
1811 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * silc_server_whois_send_reply crashed the server if the nickname
1814 was 127 characters long. Affected file silcd/command.c.
1816 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Added sanity check to the silc_server_new_client. If the hostname
1819 is provided inside username then check that the provided hostname
1820 really is the same as the resolved one. If the hostname was not
1821 resolved then check it from the public key. Affected file is
1822 silcd/packet_receive.c.
1824 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1825 if the server disconnected us and the connection is not valid
1826 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1828 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1829 the library to the lib/silcutil/silcutil.[ch].
1831 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Close log file after open. Affected file
1834 lib/silcutil/silclog.c.
1836 * Check whether sock == NULL in silc_client_send_packet and return
1837 if it is. Affected file lib/silcclient/silcclient.c.
1839 * Check rec->entry == NULL in the Irssi SILC Client before
1840 sending the channel message. Affecte file is
1841 irssi/src/silc/core/silc-servers.c.
1843 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1845 * Merged a splitted window bugfix from Irssi CVS tree. The
1846 affected file is irssi/src/fe-text/textbuffer-view.c.
1848 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1849 It did not print nickname.
1851 * Improved the distributions system a bit.
1853 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1856 irssi/src/fe-text/gui-window.c.
1858 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1859 to in-active server. The affected file is
1860 irssi/src/silc/core/client_ops.c.
1862 * Resolve the client in USERS command reply if the entry does
1863 not have username resolved. The affected file is
1864 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1865 command to WHOIS command to really resolve stuff. The USERS
1866 is not used any more in any critical section so WHOIS can
1867 be used even though it might be slower than IDENTIFY.
1869 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1872 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Changed the protocol API a bit more consistent in the
1875 lib/silccore/silcprotocol.[ch].
1877 * Changed the following headers to ROBODoc format:
1879 lib/silccore/silcpayload.h
1880 lib/silccore/silcprotocol.h
1881 lib/silccore/silcsockconn.h
1883 All core library headers are now formatted.
1885 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1887 * Fixed a bug in Irssi SILC client; do not show that you are
1888 server/router operator if you really are not. Affected file is
1889 irssi/src/silc/core/client_ops.c.
1891 * Renamed silc_command_free_payload to silc_command_payload_free.
1892 Affected file lib/silccore/silccommand.h
1894 * Added silcmath.h to include the prototoypes of various routines
1895 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1898 * Changed the following headers to ROBODoc format:
1900 lib/silccore/silcchannel.h
1901 lib/silccore/silccommand.h
1902 lib/silccore/silcid.h
1903 lib/silccore/silcidcache.h
1904 lib/silccore/silcmode.h
1905 lib/silccore/silcnotify.h
1906 lib/silccore/silcpacket.h
1907 lib/silcmath/silcmath.h
1909 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Added checking to the server code not to start the server if
1912 ciphers and stuff are not configured properly. Affected files
1913 silcd/serverconfig.[h] and silcd/server.c.
1915 * Changed the layout of the header files of the public interfaces
1916 in the SILC libraries. The new layout supports ROBODoc
1917 documentation tool (and some others) so that it is easy to create
1918 a library reference manual. All the other headers and source
1919 code must still follow the CodingStyle document. Also source
1920 code must not include these ROBODoc stuffs, only the headers.
1921 Furthermore, all public interface headers must now be named
1922 by using `silc' prefix, example: silcapi.h, silccipher.h.
1923 Some files were renamed due to this. All the other headers
1924 must not be used as public interfaces. I will update the
1925 CodingStyle document later. Changed following headers, so far:
1927 lib/silcclient/silcapi.h
1928 lib/silccore/silcauth.h
1929 lib/silccore/silcprivate.h
1930 lib/silccrypt/silcdh.h
1932 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Removed silc_client_packet_send_flush from the client library
1937 as it is not needed. Affected file lib/silcclient/client.[ch].
1939 * Added printing of message of unresolved authentication method
1940 to the Irssi SILC client. Added it to the module formats.
1941 Removed the same message from the client library.
1943 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Added new distribution feature, DISTLABEL. Every distribution
1946 can define own preprocessor label that can be used in the
1947 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1948 file distributions, acconfig.h.pre and prepare.
1950 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Added Makefile.defines_int to include the actual definitions
1953 for Makefile.defines.in. Tested the new distribution system,
1954 created distributions and tested installation.
1956 * Added AWAY message printing to the Irssi SILC client. Added
1957 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1959 * Added SCONNECT command to call the SILC's CONNECT command.
1960 Cannot use CONNECT directly since Irssi uses that internally.
1961 Affected file irssi/src/silc/core/silc-servers.c.
1963 Added ACTION local command. It is same as ME command but takes
1964 the channel as mandatory argument.
1966 Rewrote some of the Irssi's help files to suite for SILC
1969 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Added Makefile.defines[.in] that should for now on be included
1972 in all Makefile.am file in the source tree. That file includes
1973 all common compilation definitions for SILC source tree.
1975 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Minor changes to the ./prepare script to change the package
1978 name according the distribution name to the configure.in.
1980 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Created new distribution system. Added file `distributions'
1983 that defines all the distributions that can be created out of
1984 the SILC source tree. The ./prepare script now reads that
1985 file to determine how to prepare the distributions. The
1986 first argument to the ./prepare is the name of the distribution
1987 and second is the version of the distribution. If given
1988 without arguments it creates the default (toolkit) distribution
1989 with the default version (defined in ./prepare).
1991 All Makefile.am files that are subject to the distributions
1992 are now named as Makefile.am.pre. These are ./Makefile.am
1993 and lib/Makefile.am. Others may be changed later.
1995 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Added invite list, ban list, some key management and connection
1998 error message printing to module formats in the Irssi SILC client.
2000 * Added new silc_client_set_away_message to set the away message
2001 that is back to the person who sent private message. The
2002 affected file lib/silcclient/silcapi.h and the
2003 lib/silcclient/client_prvmsg.c.
2005 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Fixed the private message sending in the Irssi SILC client,
2008 added local command KEY to the Irssi SILC client.
2010 Added key management and key agreement message formats to the
2011 irssi/src/fe-common/silc/module-formats.[ch].
2013 Added USERS (alias WHO) printing, server/router operator
2014 indication and LIST command printing to the module formats.
2016 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Fixed channel joining notify handling, cumode notify handling
2019 from Irssi SILC client.
2021 * Added SILC specific module-formats to the Irssi SILC client so
2022 that SILC specific message hilighting, colors etc is possible.
2023 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2025 Added channel mode, channel user mode, actions, notices,
2026 whois and whowas printing to the the module-formats.c.
2028 * Fixed a bug in channel deletion in the server. The channel
2029 is not left to the cache even if the channel founder auth mode
2030 is set when there are no users anymore on the channel. Affected
2031 file silcd/server.c.
2033 * The silc_net_localhost now resolves the entire hostname including
2034 the domain name. Affected file lib/silcutil/silcnet.c.
2036 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Changed the ask_passphrase client operation to be ascynchronous.
2039 It has now a completion callback and a context that the
2040 application must call after it has got the passphrase from
2041 the user. Affected files lib/silcclient/silcapi.h,
2042 lib/silcclient/protocol.c, lib/silcclient/command.c and
2045 Added SilcAskPassphrase callback that the application calls
2046 to deliver the passphrase to the library.
2048 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2049 The public key verification and especially a certificate
2050 verification is asynchronous procedure.
2052 Added new SILC_SKE_STATUS_PENDING status to indicate the
2053 request is pending and a callback will be called to finalize
2056 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2057 indicate that remote end did not send its public key (or
2058 certificate), even though we require it. Added check for this
2059 condition in the SKE. This was a security bug, now fixed.
2061 Defined new SilcSKEVerifyCbCompletion callback that is called
2062 when the verification process is completed.
2064 The affected files lib/silcske/silcske_status.h and
2065 lib/silcske/silcske.[ch].
2067 * Changed the verify_public_key client operation to be async
2068 as well. Defined SilcVerifyPublicKey callback that is used to
2069 indicate the success of the public key verification process.
2071 Changed the server and client to use the new async client
2074 * Changed the Irssi SILC client's internal scheduler to be called
2075 twice as many times as it used to be. As a result the client
2076 should be a bit faster now. Affected file is
2077 irssi/src/silc/core/silc-core.c.
2079 * Added support to Irssi SILC client of asynchronous public key
2080 verification and passphrase inquiry. Affected file is
2081 irssi/src/silc/core/silc-core.c.
2083 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Do not say "You have left channel %s" in client library.
2086 Moved it to the application. Affected files are
2087 lib/silcclient/command.c and silc/client_ops.c.
2089 * Fixed silc_client_get_clients. Command context was not
2090 duplicated and was freed memory in the callback. Affected
2091 file lib/silcclient/idlist.c.
2093 * Do not say "you are now talking..." on JOIN command in the
2094 client library. The appliation must handle it.
2096 * Do not say ".. changed topic to" in command reply in the
2097 client libary. The application must handle it.
2099 * Fixed TOPIC command sending in the client library.
2101 * Fixed a memory leak in silc_client_command_free in the file
2102 lib/silcclient/command.c.
2104 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Imported a modified version of Irssi client to the source tree.
2107 The Irssi will be used to create a new client called
2108 Irssi SILC. Imported to irssi/.
2110 Added silc_core_init_finish function to the Irssi. Affected
2111 file irssi/configure.in.
2113 A lot changes in the Makefile.ams around the irssi tree.
2115 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Do not rehash if the new size is same as the old size of the
2118 hash table, in the silc_hash_table_rehash*. The affected file
2119 lib/silcutil/silchashtable.c.
2121 * Replaced hash_table_del_by_context calls from the server
2122 (when channel->user_list and client->channels) to the
2123 hash_table_del as it is sufficient and faster.
2125 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Added silc_hash_table_list, silc_hash_table_get and the
2128 SilcHashTableList structure to provide an alternative way to
2129 traverse the hash table. The affected files are
2130 lib/silcutil/silchashtable.[ch].
2132 * Changed the server's idlist routines to use the hash table
2133 routines to optimize the code.
2135 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2137 * Replaced the client entry's `channel' list and channel entry's
2138 `user_list' list to hash tables for optimized lookup. Changed
2139 the code to use the hash table interface around the code.
2140 Affected file lib/silcd/idlist.[ch].
2142 * Added `auto_rehash' boolean argument to the function
2143 silc_hash_table_alloc to indicate whether the hash table should
2144 auto-rehash when it thinks is appropriate time. It will
2145 increase the hash table size if the there is twice as much
2146 entries in the table than the size of the table, and will
2147 decrease the size if there are twice as less entries than
2148 the size of the table.
2150 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2154 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * silc_idcache_purge_by_context deletes the entry now by context
2157 as it is supposed to do. Affected file lib/silccore/idcache.c.
2159 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2160 client is not anymore valid (WHOWAS givens the info) and not
2161 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2163 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Removed the `data' and `data_len' arguments from the ID Cache
2166 interfaces and added `name' argument. ID Cache does not handle
2167 anymore the binary data only a names associated with given ID.
2169 * When hashing a Client ID with silc_hash_id the entire ID is
2170 not hashed anymore, instead only the hash of the Client ID is
2171 hashed. This way we can access the Client ID from the cache
2172 with Client ID but with the hash of the ID (which is a hash of
2173 the nickname) as well without any difference in performance.
2175 Added also silc_idcache_find_by_id_one_ext to do one on one
2176 searching when we have the actual ID. Added also function
2177 silc_hash_client_id_compare. The affected files are
2178 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2180 * When hashing the name associated with a ID it is always done
2181 in lowercase. This way we can access the cache without worrying
2182 about case-sensitivity, even though, for example nicknames are
2185 * Fixed a bug in server with channel message sending. It put
2186 wrong ID type as destination ID. The affected file
2187 silcd/packet_send.c.
2189 * silc_idcache_del_by_context now deletes from all hash tables
2190 by context. Affected file lib/silccore/idcache.c.
2192 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Changed the client library to use the new ID Cache interface.
2195 Changes around the source tree.
2197 * Added silc_hash_table_rehash_ext to rehash with specific
2198 hash function. Affected file lib/silcutil/silchashtable.[ch].
2200 * Added silc_hash_string_compare to compare two strings in the
2201 hash table. Affected file lib/silcutil/silcutil.[ch].
2203 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2205 * Added new function silc_idcache_del_by_context into the
2206 lib/silccore/idcache.[ch].
2208 * Changed the server's ID list routines to use the new ID Cache
2209 interface. Changes around the source tree.
2211 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Added silc_hash_table_del[_by_context]_ext functions in to the
2214 lib/silcutil/silchashtable.[ch].
2216 Removed silc_hash_table_find_all* routines and added new
2217 silc_hash_table_find_foreach to replace them.
2219 Added silc_hash_table_replace_ext function as extended
2220 replacing function. Separated the simple hash table interface
2221 from the extended hash table interface in the file
2222 lib/silcutil/silchashtable.h.
2224 * Fixed minor bugs and changed it to use some of the new
2225 hash table functions in lib/silccore/idcache.c
2227 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Added new function silc_hash_table_find_all to return all keys
2230 in the hash table by the specified key. As the hash table is
2231 collision resistant it also makes it possible to have several
2232 duplicate keys in the hash table. This function may be used to
2233 find all of the keys from the hash.
2235 Added user_context arguments to the SilcHashFunction,
2236 SilcHashCompare and SilcHashDestructor to deliver user specified
2239 Added new fuctions silc_hash_table_find[_all]_ext to do
2240 extended lookup with specified hash and compare functions and
2241 specified user contexts.
2243 Added new function silc_hash_table_add_ext to add the key
2244 with specified hash function and user context.
2246 Added new function silc_hash_table_foreach to traverse all
2247 entrys in the hash table. Added SilcHashForeach callback
2250 Added new function silc_hash_table_del_by_context to delete
2251 the entry only if the context associated with the key matches.
2253 Affected files are lib/silcutil/silchashtable.[ch].
2255 * Removed silc_hash_[server/client/channel]_id and added just
2256 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2257 silc_hash_id_compare to compare two ID's using as the hash table
2258 comparison function. Added also silc_hash_data to hash
2259 binary data and silc_hash_data_compare to compare it.
2261 * Removed silc_idlist_find_client_by_hash as it is not needed
2262 anymore. Affected file silcd/idlist.[ch].
2264 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2265 to use internally the SilcHashTable. The new ID Cache is a lot
2266 faster than the old one. Some of the ID Cache interface was also
2267 rewritten and obsolete and stupid functions were removed.
2269 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Added entry_count field to the SilcHashTable to keep the number
2272 of the entries in the table. Implemented the function
2273 silc_hash_table_rehash. Added new function
2274 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2276 Fixed a minor bug in silc_hash_table_free.
2278 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2279 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2280 into the lib/silcutil/silcutil.[ch].
2282 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Implemented a collision resistant hash table into the
2285 lib/silcutil/silchashtable[ch]. See the header and the source
2286 for the SilcHashTable API.
2288 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2290 * Merged dotconf version 1.0.2 into lib/dotconf.
2292 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2294 * Do not compile anything in lib/silcsim/* if the SIM support
2295 is not enabled. The tree should now compile without problems
2298 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * Compiled the SILC under cygwin. Compiled and tested briefly
2301 without problems. More tests needed. The SIMs didn't compile
2304 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2306 * Fixed possible crash in silc_get_username in the
2307 lib/silcutil/silcutil.c.
2309 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Fixed a va_arg in silc/client_ops.c.
2313 * Oops, RC5 routines were named AES and caused some problems
2314 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2316 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Added new SilcIDIP structure into the lib/silccore/id.h and
2319 replaced the old `ip' fields from all SILC ID's to that type.
2320 This is a step towards IPv6 support.
2322 The silc_id_get_len takes now the ID as an extra argument.
2323 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2324 both IPv4 and IPv6 based ID's.
2326 The affected files are lib/silccore/id.[ch] and other files
2327 around the tree using these routines.
2329 * Removed the ID length arguments in server from various
2330 silc_server_send_notify_* routines -> they are not needed
2333 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2335 * Fixed memory leak in silc_encode_pem_file in the file
2336 lib/silcutil/silcutil.c.
2338 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Check minor version as well in the SKE. Affected files are
2341 silcd/protocol.c and lib/silcclient/protocol.c.
2343 * Added --identifier option to the server so that an identifier
2344 can be when creating the public key for the server. Affected
2345 file is silcd/silcd.c.
2347 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2348 lib/silccrypt/silcpkcs.c.
2350 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Register default ciphers and stuff when using -C option with
2353 the server. Affected file sildc/silcd.c.
2355 * Put back the servers public key filename format, it is better
2356 than the new one. For now, the client keys are saved with the
2357 new filename format. The affected file silc/client_ops.c.
2359 * Implemented the Cipher API for the rest of the ciphers that
2360 did not implement it or implemented it the wrong way.
2362 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Register default ciphers and stuff when using the -S option
2365 in the client. Affected file silc/silc.c. Same also when
2366 creating new key pair with -C option.
2368 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Fixed the silc_verify_public_key client operation function to
2371 save the public keys differently. The fingerprint is now
2372 used as filename and not the hostname. This way also the
2373 client keys are saved uniquely and not with hostnames. The
2374 affected file is silc/client_ops.c.
2376 * Trimmed the silc_hash_fingerprint function to remove extra
2377 whitespaces from the end of the fingerprint. The affected
2378 file is lib/silccrypt/silchash.c.
2382 * Added silc_cipher_register_default function to register all
2383 default ciphers. It can be used when configuration files
2384 does not exist and the application does not want any specific
2385 ciphers in any specific order.
2387 The SilcDList is now used as silc_cipher_list dynamically
2388 allocated cipher list. Removed the static list all together
2389 and now all ciphers must be allocated to the dynamic list.
2390 The silc_cipher_alloc routine was changed to check only the
2393 All silc_cipher_* routines that used to return int returns
2396 The affected files lib/silccrypt/silccrypt.[ch].
2398 * The same thing was done to silc_hash_* as for silc_cipher_*
2399 routines. Affected files lib/silccrypt/silchash.[ch].
2401 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2402 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2403 Added also silc_pkcs_[un]register[_default] functions.
2404 Removed the data_context from the PKCS API.
2406 * Added silc_hmac_register_default function to register default
2407 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2408 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2409 to unregister all hmacs at once.
2411 * Register the default ciphers, hash functions, PKCSs and HMACs
2412 if client's configuration file does not exist. The affected
2415 * The client did not load the hash functions from the SIM
2416 modules at all. Added support for this. Affected file is
2417 silc/clientconfig.c.
2419 * When decoding public key with silc_pkcs_public_key_decode, check
2420 the supported algorithm only if PKCS are registered. Affected
2421 file lib/silccrypt/silcpkcs.c. The same was done with the
2422 silc_pkcs_private_key_decode.
2424 * Fixed the SILC List routines to keep the list always in order.
2425 It used to change the list's order when traversing the list but
2426 not it preserves the order. Affected file lib/trq/silclist.h.
2428 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2430 * Added the client library to use the SilcSocketConnection's
2431 reference counter (by silc_socket_dup) to prevent the bug that
2432 the socket object may be freed underneath async operation.
2434 * The name resolv library checking fixes in the configure.in.pre.
2437 * Created new version of the protocol drafts for future
2438 development. The -03 drafts are the ones that will be changed
2439 in the trunk now and the -02 will remain as they are.
2441 * Send list of CUMODE notifys to the router when announcing
2442 the channel users to the router. Affected file silcd/server.c.
2443 If the router receiving channel founder CUMODE for a channel
2444 that already has channel founder it will send CUMODE notify
2445 to the sender to remove the channel founder rights from the
2446 announced client. Affected file silcd/packet_receive.c.
2448 * The CUMODE notify may now use Server ID as well as the entity
2449 who changes the mode. Updated protocool specs.
2451 * Updated INSTALL and README files.
2453 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * New web pages in the http://silc.pspt.fi. The pages was
2460 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Implemented the [DenyConnectin] config section in the server.
2463 Added silc_server_config_denied_conn to check whether incoming
2464 connection is denied. Affected file silcd/serverconfig.[ch].
2466 * Do not check the ports when checking the incoming configuration
2467 data if the port is 0, meaning any. Affected file is
2468 silcd/serverconfig.c.
2470 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2472 * Fixed buffer overflow in silc_string_compare in the file
2473 lib/silcutil/silcutil.c.
2475 * Fixed double free in silc_server_command_leave in the file
2478 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2480 * Fixed the version checking in the server. Affected file is
2483 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Fixed the configuration data fetching when accepting new
2486 connections in the server. Affected file silcd/server.c.
2488 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Added `sender_entry' argument to the function
2491 silc_server_packet_relay_to_channel so that we can check
2492 whether some destination actually belongs to the same route
2493 the sender belongs (ie, we must not resend the packet to the
2494 sender). Affected file silcd/packet_send.[ch].
2496 * Added `servername' field to the SilcClientEntry in the server
2497 to hold the name of the server where client is from. Affected
2498 file is silcd/idlist.h.
2500 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2502 * Moved the channel message encrypting in the router betwen
2503 router connections from silc_server_channel_message to the
2504 silc_server_packet_relay_to_channel since we want to check
2505 whether we have anybody channel before encrypting anything.
2506 Affected files silcd/packet_[receive/send].c.
2508 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2510 * Fixed the [AdminConnection] server config section to support
2511 multiple entries. Affected file silcd/serverconfig.c.
2513 * Added support into the server to check the validity of the
2514 incoming connection before executing any KE or authentication
2517 * The connection configuration is now saved to the KE and
2518 connection auth protocol contexts and not fetched anymore in
2519 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2521 * The local hosts listenning address and port is also resolved
2522 now when starting the server. We want to have the socket object
2523 to include the real address and port for the listener. Added
2524 new function silc_net_check_local_by_sock into the files
2525 lib/silcutil/silcnet.[ch].
2527 * Fixed a broadcast bug in server -> do not broadcast if we
2530 * Fixed a routing bug. Do not route broadcast packets ever.
2531 Broadcast packets must be processed always and not routed since
2532 they may be destined to some other host than yourself and thus
2533 would get routed without no good reason. Affected file is
2536 * Added function silc_server_config_is_primary_route to check
2537 whether primary router connection has been configured (a router
2538 configuration that we are initiating). If there is not, we
2539 will assume that there is only two routers in the SILC network
2540 and we will use the incoming router connection as our primary
2541 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2543 * Changed the order of the broadcasting. Broadcast _after_ the
2544 packet has been processed not before. Affected file is
2547 * Fixed a [ClientConnection] parsing bug. The port was never
2548 parsed correctly thus resulting to port 0. Affected file
2549 silcd/serverconfig.c.
2551 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2552 argument and did not set the broadcast packet flag. Affected
2553 file silcd/packet_send.c. Fixed same bug in the function
2554 silc_server_send_notify as well.
2556 * If we receive NEW_ID packet for our own ID in the server, ignore
2559 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2563 * Removed the nickname from the Private Message Payload.
2564 Updated the code and the protocol specs.
2566 * Updated protocol specs for submitting to the IETF.
2568 * Tweaked the Random Number Generator a bit. Affected file
2569 lib/silccrypt/silcrng.c. Exported a new function
2570 silc_rng_[global]_add_noise which can be used to add more
2573 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Do not parse packets with different timeout when protocol
2576 is active -> may cause problem with rekey. Affected file
2579 * When server receives signoff notify it must not create
2580 new channel key if the client is on any channels since the
2581 sender of the signoff notify will create it.
2583 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2585 * Added printing of error messages during SKE protocol from the
2586 failure packet sent by server during SKE. Affected file
2589 * Removed the client's failure_callback handling with timeout
2590 and handle it immediately when received.
2592 * The SKE library returned wrong type in SUCCESS and FAILURE
2593 packets. They must be 32 bit MSB not 16 bit MSB.
2595 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2597 * Ok, rewrote the logic of the re-key and now it seems to work.
2598 I tested it on high traffic with frequent re-keys without
2599 problems. Added hmac_receive (and renamed hmac to hmac_send)
2600 in SilcClientConnection in lib/silcclient/client.h and
2601 in SilcIDListData in silcd/idlist.h. Also, removed the
2602 SilcPacketParserContext's cipher and hmac fields as they are
2603 not needed anymore and actually caused some problems when
2604 the ciphers and hmac's changed underneath the packet parser.
2606 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * If re-key protocol is active then process the incoming packets
2609 synchronously since we must assure that icoming packets encrypted
2610 with the old key is processed before the new keys is set to
2611 use. This is true other packets than for REKEY packets.
2612 Affected file silcd/server.c. The same was done to client library
2613 as well, affected file lib/silcclient/client.c.
2615 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Fixed bug in client and server to accept the force send if
2618 the packet is send from silc_[server/client]_packet_process
2619 function. Otherwise the packets are never delivered, oops.
2621 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Disable force sending of packets when REKEY protocol is active.
2624 We must assure that no packet is sent directly when rekey is
2625 performed. All packets must be sent through packet queue.
2626 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2627 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2628 function is silc_[server/client]_packet_send_real to check
2631 * Replaced the SIM paths from example config files to
2632 /usr/local/modules. Also, make install creates now
2633 /usr/local/silc/logs directory to hold all the SILC server
2636 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Made the configure.in.pre work on Solaris. Patch by salo.
2640 * Made all ciphers compatible with non-x86 machines. Defined
2641 CBC mode macros into lib/silccrypt/ciphers_def.h.
2643 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2645 * Fixed the make install.
2647 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * When MAC computation fails the silc_packet_decrypt returned 0
2650 even though it was supposed to return -1. Fixed this. The
2651 affected file is lib/silccore/silcpacket.c.
2653 * Do not replace the config files in /etc/silc (in make install)
2654 if they already exist. Affected file ./Makefile.am.
2656 * Do not send re-key packets immediately but through packet queue.
2657 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2659 * Changed silc_net_check_host_by_sock to return FALSE if the
2660 IP/DNS could not be resolved. Though, it returns the IP address
2661 now even if it could not resolve it (but returns also FALSE).
2662 Affected file lib/silcutil/silcnet.[ch].
2664 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2672 contents of the specified public key file.
2674 * Changed the PKCS api to return the public key length when
2675 setting the public key.
2677 * Fixed a fatal bug in the public and private key file loading.
2678 Affected file lib/silccrypt/silcpkcs.c.
2680 * Execute the packet parsing for client with zero (0) timeout
2681 if the protocol is active. Affected file silcd/server.c.
2683 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2685 * Made the key generation options to the silcd program. Added
2686 -C option, equivalent to client's option.
2688 * Added new [ServerKeys] config section to the server. It
2689 configures the server's public and private key.
2691 * Defined generic Public Key Payload into the protocol
2692 specification to send specific type of public keys and
2695 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2696 public key or certificate.
2698 * Implemented the GETKEY command to the server and to the
2699 client library and on user interface.
2701 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

2705 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Added SilcServerRekey context into silcd/idlist.h.
2709 * Added the PFS support as defined in the specification to the
2710 SKE protocol. Affected files lib/silcske/*.c.
2712 * Added `ske_group' field to the SilcServerRekey context to hold
2713 the number of the SKE group that is used with PFS in re-key.
2714 Affected file silcd/idlist.h.
2716 * Added PFS re-key support to the server. Affected file is
2719 * Added silc_protocol_cancel to cancel execution of the next
2720 state of the protocol. Affected file is
2721 lib/silccore/silcprotocol.[ch].
2723 * Added the re-key support with and without PFS to the client
2724 library. Re-key is performed once in an hour, by default.
2726 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2727 Added silc_client_rekey_callback and silc_client_rekey_final.
2728 Affected files are lib/silcclient/protocol.[ch] and
2729 lib/silcclient/client.[ch].
2731 * Removed the `hmac_key' and `hmac_key_len' fields from the
2732 SilcClientConnection structure; not needed. Affected file is
2733 lib/silcclient/client.h.
2737 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Do not ask whether user wants to use the negotiated private key
2740 for private messages, just use it. Affected file is
2741 silc/local_command.c.
2743 * Added `send_enc_key' and `enc_key_len' fields to the
2744 SilcIDListData structure since they are needed in the re-key
2745 phase. Affected file is silcd/idlist.[ch].
2747 * Implemented the simple re-key protocol into the server.
2748 Affected files silcd/server.c and silcd/protocol.[ch]. The
2749 re-key will be performed once in an hour, by default.
2751 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2752 Added silc_server_rekey, silc_server_rekey_callback and
2753 silc_server_rekey_final.
2755 * Removed Tunneled flag from the protocol. Updated the code
2756 and the specifications.
2758 * Adde `pfs' field to the SilcIDListData to indicate whether
2759 the PFS is to be performed in the re-key. Affected file is
2762 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2764 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2765 int64 of at least the xintXX size. If void * is less that 4
2766 bytes uint32 * will be used. Defined bool as boolean.
2768 * Changed _ALL_ unsigned long and unsigned int to uint32,
2769 unsgined short to uint16 in the source tree.
2771 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2772 not handle clients that has entry->data.registered == FALSE.
2773 They are not in the network anymore. Affected file is
2776 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Implemented the sending of the SERVER_SIGNOFF notify in the
2779 server. Affected file is silcd/server.c.
2781 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2782 Added also silc_notify_payload_encode_args into the
2783 lib/silccore/silcnotify.[ch].
2785 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2786 Affected file silcd/packet_receive.c.
2788 * Implemented the SERVER_SIGNOFF notify handling in the client
2789 library. Affected file lib/silcclient/client_notify.c. Also,
2790 implemnted the printing of the SERVER_SIGNOFF info to the
2791 application. Affected file silc/client_ops.c.
2793 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2794 if the deleting was successful. Affected file silcd/idlist.[ch].
2796 * Added support for public key authentication in the connection
2797 authentication protocol in the client library. Affected file
2798 lib/silcclient/protocol.c.
2800 * Changed the server's silc_idlist_get_clients_by_* interface
2801 to support already allocated array so that new entries may be
2802 added to pre-allocated array. Affected file silcd/idlist.[ch].
2803 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2804 and command replies.
2806 * All command reply functions in the server now calls the
2807 pending command callback even if error occured. This way the
2808 error will be delivered to the client as well. Affected files
2809 silcd/command.c and silcd/command_reply.c.
2811 * Fixed INFO command to return local server's info if no server
2812 was provided. Affected file lib/silcclient/command.c.
2814 * Removed RESTART command for good. Updated the code and the
2817 * Rewrote parts of the task system. It is a bit simpler now.
2818 Removed unsued task priorities. The affected files are
2819 lib/silcutil/silctask.[ch].
2821 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Moved the USERS printing from the library to the application.
2824 Affected files lib/silcclient/command.c and silc/client_ops.c.
2826 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Added channel key re-key support. The re-key is perfomed
2831 only by the router and is done once in an hour. Added `rekey'
2832 field to the SilcChannelEntry in the server. Affected files
2833 silcd/server.c and silcd/idlist.h.
2835 * Added silc_task_unregister_by_context into the file
2836 lib/silcutil/silctask.[ch].
2838 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Added SILC_UMODE_GONE mode to indicate when the client is not
2841 present in the SILC network. Added also support to the local
2842 command AWAY that will set this mode. Added support of showing
2843 "xxx is gone" in WHOIS command. The USERS command shows the
2844 gone status as well.
2846 * Fixed setting server and router operator privileges in the
2847 server's UMODE command. Affected file silcd/command.c.
2849 * Merged the SKE KE1 and KE2 payloads into one payload. The
2850 new KE payload is equivalent to the old KE2 payload.
2852 Cleaned up the SKE Start Payload parsing. It now uses the
2853 simple buffer unformatting to do the parsing. A lot faster
2856 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2857 to the SKE that is used to indicate whether both of the SKE
2858 parties should perform authentication. By default only the
2859 responder performs authentication. By setting this flag also
2860 the initiator must do authentication. By default it is unset
2861 since in normal SKE case, client to server connection, only
2862 the responder should do authentication. When doing SKE between
2863 two clients both should perform authentication. Updated the
2864 code and the protocol specs.
2866 * A little fix to IDENTIFY command in the server. Search the
2867 client first by hash not nickname. Affected file is
2870 * Fixed the silc_client_close_connection to support closing
2871 the client to client connections wihtout deleting too much
2872 data. Affected file lib/silcclient/client.c.
2874 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2875 are received if protocol used to be active but is not anymore
2876 the application would crash due to NULL pointer dereference.
2877 Affected files silcd/server.c and lib/silcclient/client.c.
2879 * Added `hash' field to the SilcClientConnection to include
2880 the hash function negotiated in the SKE protocol.
2882 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2883 to set the channel founder authentication data. A client can
2884 claim the founder rights later by providing the authentication
2885 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2886 This way the channel founder can regain the channel founder
2887 privileges even it is left the channel. This works only on
2888 local server and the client must be connected to the same
2889 server to be able to regain the founder rights. Updated the
2890 protocol specs accordingly.
2892 Added support to the CMODE command in the client to set the
2893 founder auth data. Read the README to see how to set it.
2895 Added support to the CUMODE command to claim the founder
2896 rights. Read the README to see how to do it.
2898 Added support for the founder authentication to the Channel
2899 Entry in the server. Affected file silcd/idlist.h.
2901 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2902 server's CMODE command. Affected file silcd/command.c.
2904 * Added the following new functions into lib/silccore/silcauth.[ch]:
2905 silc_auth_get_method and silc_auth_get_data.
2907 * The server now saves the remote hosts public key to the
2908 SilcIDListData pointer. Affected file silcd/protocol.c.
2910 * The normal server now does not remove the channel entry from
2911 the cache if the founder authentication data is set. It used
2912 to remove it if the founder was the last one on the channel on
2913 the server and left the channel. The auth data is saved and
2914 if the channel is re-joined later the old entry is used with
2915 the old auth data. Affected files silcd/command_reply.c and
2918 * Removed the `pkcs' field from the SilcIDListData structure
2919 in the server; it is not used. Affected file silcd/idlist.h.
2921 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2923 * Fixed packet processing on slow links. Partial packets were
2924 never re-processed because the incoming data buffer was cleared
2925 by the application. Application must not directly clear the
2926 sock->inbuf, the packet processing routines handle it. Fixed
2927 this in client library and in server.
2929 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2931 * Fixed the WHOIS and IDENTIFY send reply function to really
2932 check whether to send list or just one entry. Affected file
2935 * Cleaned up the LEAVE command's channel key distribution. The
2936 affected file silcd/command.c.
2938 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2939 can enforce the channel mode as well. In that case the ID
2940 includes the ID of the server. The code now enforces the
2941 mode change if the router have different mode than the server.
2943 * The notify client operation with CMODE_CHANGE notify can now
2944 return NULL client_entry pointer if the CMODE was not changed
2945 by client. Application must check for this.
2947 * Added <Server ID> argument to INFO command to support server
2948 info fetching by Server ID.
2950 * Added silc_server_announce_get_channel_users to get assembled
2951 packets of channel users of the specified channel. Affected
2952 file silcd/server.[ch].
2954 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2955 was freed underneath the ID Cache.
2957 * Re-announce clients when the server received CHANNEL_CHANGE
2958 notify from the router. Affected file silcd/packet_send.c.
2960 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2962 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2963 crashed since it did not handle the fact that there is no cipher
2964 called "3" and didn't check the error condition. Now fixed.
2966 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2967 flag. It can be used to send message requests.
2969 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2971 * Implemented the RESTART command in the client.
2973 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2974 notice type messages. Added notice printing to the user
2977 * The channel keys are not re-generated if the channel's mode
2978 is PRIVKEY, ie private key on the channel exists. Affected
2979 files silcd/server.c and silcd/command.c.
2981 * Fixed a little bug in channel message delivery when channel
2982 private keys are set in the server. Affected file is
2983 silcd/packet_send.c.
2985 * Changed the setting on channel->on_channel = TRUE from the
2986 silc_client_save_channel_key to the JOIN command reply. The
2987 key payload is not received if the private channel key is set.
2988 Affected file lib/silcclient/command_reply.c and the
2989 lib/silcclient/client_channel.c.
2991 * When the CMODE_CHANGE notify is sent and the channel private
2992 key mode is removed the channel key must be re-generated in
2993 other cells as well. Added this support for the router in the
2994 silcd/packet_receive.c.
2996 * Added new local command NOTICE to send notice message on
2997 channel. Affected file silc/local_command.[ch].
2999 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3001 * Added new local command ME to the client. It is used to send
3002 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3003 some action. Affected file silc/local_command.[ch].
3005 * Changed channel_message and private_message client operations
3006 to deliver the message flags to the application. Added also
3007 the `flags' arguments to the silc_client_send_channel_message
3008 and silc_client_send_private_message functions. Affected file
3011 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3013 * Redefined the Private Message Payload to support private message
3014 keys and to support the new private message flags. Updated
3015 the protocol specs. Flags makes it possible to have for example
3016 CTCP style messages.
3018 * Added new type SilcPrivateMessagePayload and defined an API
3019 for it in the lib/silcclient/silcprivate.[ch].
3021 * Tested private message private keys successfully. Tested the
3022 private message key set, unset and list commands with the new
3025 * Redefined the Channel Message Payload to include the channel
3026 message flags (equal with private message flags) to support
3027 for example CTCP style messages.
3029 * Defined some of the message (for channel and private message)
3030 flags. Updated the protocol specs and added the flags to the
3031 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3033 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Added SilcKeyAgreementStatus type to the key agreement routines
3036 to indicate the current status and error if one occured.
3037 The status types are defined in the lib/silcclient/silcapi.h.
3039 * Added new local command KEY that is used to set and unset private
3040 keys for channels, set and unset private keys for private messages
3041 with remote clients and to send key agreement requests and
3042 negotiate the key agreement protocol with remote client. The
3043 key agreement is supported only to negotiate private message keys,
3044 it currently cannot be used to negotiate private keys for channels,
3045 as it is not convenient for that purpose.
3047 * Fixed a minor pending callback setting bug in the function
3048 silc_client_get_client_by_id_resolve, now the function works.
3049 Affected file lib/silcclient/idlist.c.
3051 * Added function silc_net_get_local_port to get local bound
3052 port by socket. Added to lib/silcutil/silcnet.[ch].
3054 * Added `sockets' and `sockets_count' fields to the SilcClient
3055 object. They hold the sockets of the listenning sockets in
3056 the client. Listenning sockets may be for example the key
3057 agreement server. Affected file lib/silcclient/client.[ch].
3058 Added functions the silc_client_add_socket and the
3059 silc_client_del_socket. They are exported to the application
3062 * Added ~./silc/clientkeys to support other client's public keys.
3064 * Renamed verify_server_key client operation to verify_public_key
3065 and added one argument to indicate the type of the connection
3066 (server, client etc.).
3068 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Added silc_server_connection_auth_request to handle the
3071 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3072 silcd/packet_receive.[ch].
3074 * Added silc_server_send_connection_auth_request into the
3075 silcd/packet_send.c to send the connection auth request packet.
3077 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3080 * Fixed the public key authentication in responder side in the
3081 server. The `auth_data' pointer includes the SilcPublicKey
3082 not the path to the public key. Affected file silcd/protocol.c.
3084 * Implemented the public key authentication in the initiator side
3085 in the server. Affected file silcd/protocol.c.
3087 * Removed the [RedirectClient] config section from the server
3088 configuration. Is not needed and I don't want to implement it.
3090 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Cleaned up the CMODE command in the server. It now works
3093 correctly and supports all the modes defined in the protocol.
3094 Affected file is silcd/command.c.
3096 * Added `hmac_name' field to the SilcChannelEntry in the server
3097 to hold the default HMAC of the channel. It can be set when
3098 creating the channel (with JOIN command). Affected files
3101 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3102 type to indicate the change of the current cipher and hmac
3103 on the channel. Client can safely ignore the <cipher> argument
3104 (if it chooses to do so) since the CHANNEL_KEY packet will
3105 force the channel key change anyway. The <hmac> argument is
3106 important since the client is responsible of setting the new
3107 HMAC and the hmac key into use.
3109 * Fixed the CMODE command in the client library as well.
3111 * Tested CMODE command in router environment successfully.
3113 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Show the version of the remote client (or server) when connecting
3116 to the server. It is logged to the log file. Affected file
3117 is silcd/protocol.c.
3119 * Fixed the KILLED notify handling in the client library. The
3120 client must be removed from all channels when receiving the
3123 Also, do not remove the client entry when giving the KILL
3124 command but when the KILLED notify is received.
3126 * Removed silc_idlist_find_client_by_nickname from the server.
3127 Not needed anymore. Affected files silcd/idlist.[ch].
3129 * Implemented the CHANNEL_CHANGE notify type handling to the
3130 server. Affected file silcd/server.c.
3134 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3136 * Added silc_server_send_notify_invite to send the INVITE
3137 notify between routers.
3139 * Implemented the INVITE command correctly to the server.
3141 * Implemented the INVITE notify type handling in the server.
3143 * Implemented the INVITE command to the client library and on the
3146 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3148 * Added function silc_server_get_client_resolve to find the
3149 client entry by ID from all ID lists and then resolve it
3150 (using WHOIS) if it cannot be found. Affected file is
3153 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Implemented the BAN command to the client library.
3157 * The JOIN command in the server now checks the invite list
3160 * Changed the silc_command_reply_payload_encode_va and the
3161 silc_command_payload_encode_va to support that if argument is
3162 NULL it ignores and checks the next argument. Affected file
3163 lib/silccore/silccommand.c.
3165 * Added silc_server_send_notify_ban to send the BAN notify
3166 type between routers.
3168 * Chaned the silc_notify_payload_encode to support that if
3169 argument is NULL it ignores and checks the next argument.
3170 Affected file lib/silccore/silcnotify.c.
3172 * Tested ban lists in router environment successfully.
3174 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Implemented BAN command to the server, in silcd/command.[ch].
3178 * Removed the BAN and INVITE_LIST modes from the CMODE command
3181 * Added function silc_string_match to regex match two strings.
3182 Affected files lib/silcutil/silcutil.[ch].
3184 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3186 * Redefined parts of the SilcChannelEntry in the server to support
3187 the new ban and invite lists.
3189 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Redefined the INVITE command. The same command can be used to
3192 invite individuals to the channel but also to manage the invite
3193 list of the channel (to add to and remove from the invite list).
3194 Updated the protocol specs.
3196 * Added new command SILC_COMMAND_BAN that can be used to manage
3197 the ban list of the channel. Updated the protocol specs.
3199 * Removed the channel modes: the SILC_CMODE_BAN and the
3200 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3201 in the CMODE command. The equivalent features are now available
3202 using INVITE and BAN commands. Updated the protocol specs.
3204 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3205 in the network about change in the current ban list. The notify
3206 type is not used by the client.
3208 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3209 support the invite lists.
3211 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3213 * Added new function silc_string_regexify that converts string
3214 including wildcard characters into regex string that can
3215 be used by the GNU regex library. Added into the file
3216 lib/silcutil/silcutil.[ch].
3218 Added silc_string_regex_combine to combine to regex strings
3219 into one so that they can be used as one regex string by
3220 the GNU regex library. Added into the file
3221 lib/silcutil/silcutil.[ch].
3223 Added silc_string_regex_match to match two strings. It returns
3224 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3226 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Imported GNU regex to the soruce tree into lib/contrib.
3229 Fixed some compiler warning from the regex.c.
3231 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Fixed MOTD command in the server to work in router environment.
3235 * Fixed the MOTD command in the client library to support
3236 the server argument in the command.
3238 * Added `nickname_len' argument to the silc_idlist_add_client
3239 in the server, as the `nickname' argument may be binary data
3242 * Added silc_idlist_get_channels to return all channels from
3245 * Implemented LIST command to the server. Affected file is
3248 * Implemented the LIST command to the client library and on the
3251 * Added [<user count>] argument to the LIST command reply.
3252 With private channels the user count is not shown.
3254 * Updated TODO and README.
3256 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3258 * The client entry's data.registered must be TRUE even with
3259 global client entry on global client list. The data.registered
3260 is used to check whether the client is anymore in the network,
3261 for example with WHOWAS command so it must be valid.
3263 * Fixed the WHOWAS command in the server. It now actually works
3264 in router environment. Added function into silcd/command_reply.c
3265 silc_server_command_reply_whowas_save.
3267 * Added silc_idlist_purge function to the silcd/idlist.c
3268 to periodically purge the ID Cache.
3270 * Fixed INFO command in the server. It works now in router
3271 environment. Added <server name> argument to the INFO command
3272 reply. Updated the protocol specs.
3274 * Fixed minor bug in silc_idcache_purge to not purge if the
3275 expire value is zero.
3277 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3278 they were buggy because of the WHOWAS information.
3280 * Fixed local command MSG to handle the async resolving of
3281 the remote client properly. It used to fail the first MSG.
3282 Affected file silc/local_command.c.
3284 * Added `data_len' field to SilcIDCache context.
3286 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3288 * Update TODO. Todo in commands in the server.
3290 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3293 used by routers as broadcast packet to inform other routers
3294 about the changed user mode.
3296 Implemented the notify handling in the server. Affected file is
3297 silcd/packet_receive.c. Added the function
3298 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3300 * Added new generic Channel Payload and deprecated the New Channel
3301 Payload. The New Channel Payload is now the generic Channel
3304 * Added new argument `mode' to the silc_server_send_new_channel
3305 as it is required in the Channel Payload now.
3307 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3308 and created a new and real SilChannelPayload to represent the
3309 new generic Channel Payload. Implemented the encode/decode
3310 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3312 * Added silc_server_get_client_channel_list to return the list
3313 of channels the client has joined for WHOIS command reply.
3314 Affected file silcd/server.[ch].
3316 * Implemented the channel list sending in the WHOIS command reply
3317 in server and in the client.
3319 Implemented the channel list displaying on the user interface
3320 as well. Affected file silc/client_ops.c.
3322 * Added silc_channel_payload_parse_list to parse list of Channel
3323 Payloads. It returns SilcDList list of SilcChannelPayloads.
3324 Client for example can use this function to parse the list of
3325 channels it receives in the WHOIS command reply. The caller
3326 must free the list by calling silc_channel_payload_list_free.
3327 Affected files lib/silccore/silcchannel.[ch].
3329 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Added one new argument <user mode> to the WHOIS command reply
3332 to return the mode of the user in SILC. Updated the protocol
3335 Implemented it to the server and client.
3337 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Fixed the mode printing on the user interface on joining.
3340 Affected file silc/client_ops.c.
3342 * Implemented the UMODE command and user modes in general to the
3343 client library and to the user interface.
3345 * Implemented the UMODE command to the server.
3347 * The server now sends UNKNOWN_COMMAND error status if client sends
3348 unknown command. Affected file silcd/command.c.
3350 * All server commands now handle the command identifier the right
3351 way when sending the command reply to the client. The client can
3352 use to identify the command replies with the identifier.
3354 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3356 * Added silc_server_get_client_route to resolve the route to
3357 the client indicated by the client ID. Affected file is
3360 * Added silc_server_relay_packet as general function to relay
3361 packet to arbitrary destination. This deprecates functions
3362 like _send_private_message_key, _relay_notify etc. Affected
3363 file is silcd/packet_send.[ch].
3365 Removed silc_server_send_key_agreement,
3366 silc_server_send_private_message_key and
3367 silc_server_packet_relay_notify functions from the file
3368 silcd/packet_send.[ch].
3372 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3373 server. Affected file silcd/packet_receive.[ch].
3375 * Implemented the KILL command to the client. Implemented the
3376 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3377 Affected files lib/silcclient/command[_reply].c and
3378 lib/silcclient/client_notify.c. Implemented the KILL notify
3379 printing in the user inteface.
3381 * Fixed a lot silc_parse_nick memory leaks from the client
3382 library in the file lib/silcclient/command.c.
3384 * Changed the silc_server_send_notify_on_channels's `sender'
3385 argument from SilcSocketConnection to SilcClientEntry to
3386 check the sender as entry and not as connection object and not
3387 to send to the client provided as argument. The affected file
3388 is silcd/packet_send.[ch].
3390 * The notify packets that are destined directly to the client used
3391 to not to be processed by the server. Now changed that and the
3392 server processes all notify packets. After relaying the packet
3393 to the client the notify packet is processed in the server.
3395 * The silc_server_free_client_data now checks whether there is
3396 pending outgoing traffic for the client and purges the data to
3397 the network before removing the client entry.
3399 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3402 an client is killed from the SILC Network. Updated the protocol
3405 Added new function silc_server_send_notify_killed to the
3406 silcd/packet_send.[ch].
3408 * Added function silc_server_packet_relay_notify to relay notify
3409 packets that are destined directly to a client. In this case
3410 the server does not process the notify packets but merely relays
3411 it to the client. Affected file silcd/packet_send.[ch].
3413 Added also silc_server_packet_process_relay_notify to check
3414 whereto relay the notify. Affected file is
3415 silcd/packet_receive.[ch].
3417 * Implemented the KILL command to the server.
3421 * Added the backup schema desgined last fall to the protocol
3422 specs for everyone to see. The specification is in the
3423 *-spec-xx.txt draft and the packet type definitions for the
3424 backup routers is in *-pp-xx.txt draft. Thusly, added also
3425 new packet type SILC_PACKET_CELL_ROUTERS.
3427 * A big security problem in the implementation discovered. The
3428 signoff of an client did not cause new channel key generation
3429 which it of course should've done. The channel keys must be
3430 always re-generated when client leaves (or signoffs) the channel.
3431 The silc_server_remove_from_channels funtion now handles
3432 the channel key re-generation.
3434 * Added `sender' argument to the silc_server_send_notify_on_channels
3435 to not to send the client provided as argument. Affected file
3436 silcd/packet_send.[ch].
3438 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Implemented OPER and SILCOPER commands into the server and
3443 * Added silc_auth_verify and silc_auth_verify_data to verify
3444 the authentication directly from the authentication payload.
3445 It supports verifying both passphrase and public key based
3446 authentication. Affected file lib/silccore/silcauth.[ch].
3448 * Added `hash' field to the SilcIDListData structure. It is the
3449 hash negotiated in the SKE protocol. Affected file is
3452 * Slight redesigning of the SilcAuthPayload handling routines.
3453 Do not send SilcPKCS but SilcPublicKey as argument.
3455 * Implemented the public key authentication support to the
3456 serverconfig. The public key is loaded from the provided path
3457 and saved as authentication data to void * pointer. Thus,
3458 changed the unsigned char *auth_data to void *auth_data;
3460 * Fixed SHUTDOWN command to send the reply before the server
3461 is shutdown. :) Affected file silcd/command.c.
3463 * Fixed fatal bug in CONNECT command. The hostname was invalid
3464 memory and server crashed. Affected file silcd/command.c.
3466 * Fixed fatal bug in CLOSE command. The server_entry became
3467 invalid but was referenced later in the command. Affected file
3470 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3472 * Fixed fatal bug in failure packet handling. Server ignored
3473 the failure and thus crashed when it came.
3477 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3479 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3480 that the command may be executed only once in (about) 2 seconds.
3481 The old SILC_CF_LAG flag is same but allows command bursts up
3482 to five before limiting.
3484 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3485 server code. Various commands now includes the CF_LAG_STRICT
3486 flag to disallow any kind of miss-use of the command.
3488 * Fixed the silc_buffer_unformat to not to allocate any data
3489 if the length of the data is zero. It used to allocate the
3490 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3492 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3494 * Changed the format of AdminConnection configuration section
3495 in the server. Added username of the admin to the format.
3496 Affected files silcd/serverconfig.[ch].
3498 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3499 to return admin configuration data by host, username and/or
3502 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Implemented WHOWAS command to the server. Added the functions:
3506 silc_server_command_whowas_parse,
3507 silc_server_command_whowas_send_reply,
3508 silc_server_command_whowas_from_client and
3509 silc_server_command_whowas_from_server
3511 * Added <Client ID> argument to the WHOWAS command reply. Updated
3512 the protocol specs accordingly.
3514 * Implemented WHOWAS command and command_reply to the client
3517 Implemented the WHOWAS printing on the user interface.
3519 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Added new argument to the WHOWAS command reply, the real name.
3522 It is an optional argument. Updated the protocol specs.
3524 * Added SilcIDCacheDestructor callback that is registered when
3525 the SilcIDCache is allocated. The callback is called when
3526 an cache entry in the ID Cache expires, or is purged from the
3527 cache. Added into lib/silccore/idcache.[ch].
3529 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3530 to destruct the client entries when the cache entry expires.
3531 Other ID Cache's in server and in the client library ignores
3534 * If the ID Cache entry's `expire' field is zero then the entry
3535 never expires. Added boolean `expire' argument to the
3536 silc_idcache_add function in the lib/silccore/idcache.[ch].
3537 If it is TRUE the default expiry value is used.
3539 * Added silc_server_free_client_data_timeout that is registered
3540 when client disconnects. By default for 5 minutes we preserve
3541 the client entry for history - for WHOWAS command.
3543 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Added support to the server to enforce that commands are not
3546 executed more than once in 2 seconds. If server receives
3547 commands from client more frequently, timeout is registered
3548 to process the commands. Affected file silcd/command.c.
3549 Added new function silc_server_command_process_timeout.
3551 * Changed NICK_NOTIFY handling in client library to check that
3552 if the client's nickname was changed, so there is no need to
3553 resolve anything from the server.
3555 * Removed error printing from the WHOIS and IDENTIFY commands.
3556 If error occurs then it is ignored silently in the client library.
3557 The application, however, may map the received error to
3558 human readable error string. The application currently maps
3559 the NO_SUCH_NICKNAME error to string.
3561 * Made the command status message public to the application. Moved
3562 them from lib/silcclient/command_reply.c to
3563 lib/silcclient/command_reply.h. The application can map the
3564 received command status to the string with the
3565 silc_client_command_status_message function.
3567 * Added check to the server to check that client's ID is same
3568 as the Source ID in the packet the client sent. They must
3571 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3573 * Added dist-bzip hook to the Makefile.am to make bzip2
3574 compressed distributions.
3576 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Server now enforces the maximum length for the nickname and
3579 the channel as protocol specification dictates. 128 bytes for
3580 nickname and 256 bytes for channel name.
3582 * Moved the WHOIS printing to the application. The client libary
3583 does not print out the WHOIS information anymore, the application
3584 must do it. Renamed silc_client_command_reply_whois_print to
3585 the silc_client_command_reply_whois_save.
3587 The client's idle time is also sent to the application now, and
3588 the idle is shown on screen.
3590 * Added silc_client_command_reply_identify_save to save the
3591 received IDENTIFY entries.
3593 * Do not check for channel private keys in message sending and
3594 reception if the channel does not have the PRIVKEY mode set.
3595 Affected file lib/silclient/client_channel.c.
3597 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3600 just surfaced after chaning the JOIN procedure.
3602 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Added silc_client_get_clients_by_list to get client entries
3605 from Client ID list, that is returned for example by JOIN
3606 and USERS command replies. The application should use this
3607 function for example when JOIN command reply is received to
3608 resolve the clients already on the channel (library does not
3609 do that anymore as USERS command reply is not used in the JOIN
3610 procedure anymore). Affected files lib/silcclient/silcapi.h and
3611 lib/silcclient/idlist.c.
3613 * JOIN command reply and USERS command reply returns now SilcBuffer
3614 pointers instead of unsigned char pointers when returning
3615 the client list and mode list.
3617 * Added <Client ID> argument to the JOIN command reply, mainly
3618 for the server to identify for which client the command was
3619 originally sent. Updated protocol specs accordingly.
3621 * Added SilcDlist private_key pointer to the SilcChannelEntry
3622 in the client to support the channel private keys. Affected
3623 file is lib/silcclient/idlist.h.
3625 * Added SilcChannelPrivateKey argument to the function
3626 silc_client_send_channel_message so that application can choose
3627 to use specific private ke if it wants to. If it is not provided,
3628 the normal channel key is used, unless private keys are set.
3629 In this case the first (key that was added first) is used
3630 as the encryption key.
3632 * Implemented the support for channel private key handling.
3633 Implemented the following functions:
3635 silc_client_add_channel_private_key,
3636 silc_client_del_channel_private_keys,
3637 silc_client_del_channel_private_key,
3638 silc_client_list_channel_private_keys and
3639 silc_client_free_channel_private_keys
3641 Affected file lib/silcclient/client_channel.c.
3643 * Added the support for the private keys in the channel message
3644 sending and encryption and in the message reception and
3645 decryption. Affected funtions are
3646 silc_client_send_channel_message and silc_client_channel_message.
3648 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Added SKE's key verify callback to the client library's
3651 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3653 * Removed the statement that server (or router) must send USERS
3654 command reply when joining to the channel so that the client
3655 knows who are on the channel. Instead, the client list and
3656 client's mode list is now sent in the JOIN command reply to the
3657 client who joined channel. This is better solution.
3659 * Added function silc_server_get_users_on_channel and function
3660 silc_server_save_users_on_channel to the silcd/server.[ch].
3662 * Removed function silc_server_command_send_users from the
3665 * Do not show topic on the client library anymore. The topic is
3666 sent in the command reply notify to the application and the
3667 application must show the topic now.
3669 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3671 * Added client searching by nickname hash into the IDENTIFY and
3672 WHOIS commands in the server as they were clearly missing from
3673 them. Affected file is silcd/command.c.
3675 * Fixed a bug in private message receiving in the client library.
3676 The remote ID was freed and it wasn't supposed, now it is
3679 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Minor fix to the channel payload; allocate the data area, as it
3682 needs to be of specific length.
3684 * If the key agreement port is zero then the operating
3685 system will define the bound port. Affected files are
3686 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3688 * Added new function silc_channel_payload_decrypt into the file
3689 lib/silccore/silcchannel.[ch].
3691 * Moved the channel message etc, check from silc_packet_decrypt
3692 to applications. The library calls now a generic
3693 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3694 when the packet is either normal or special. This was done to
3695 allow more wide range of checking that was not allowed when
3696 the code was in library. Now applications can do virtually any
3697 checks to the packet and return to the library the decision how
3698 the packet should be processed. Affected files are
3699 lib/silccore/silcpacket.[ch].
3701 Added silc_server_packet_decrypt_check to the server and
3702 silc_client_packet_decrypt_check to the client library.
3704 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3705 to send with specified source and destination information.
3707 * Channel message delivery between routers was broken after the
3708 channel key distribution was fixed earlier. The channel key
3709 was used be to distributed to other routers as well which is not
3710 allowed by the protocol. Now this is fixed and channel keys
3711 really are cell specific and the channel message delivery between
3712 routers comply with the protocol specification.
3714 * Fixed various commands in server to check also the global list
3715 for the channel entry and not just the local list. The affected
3716 file silcd/command.c.
3718 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Added assert()s to buffer formatting and unformatting routines
3721 to assert (if --enable-debug) when error occurs. Affected
3722 file: lib/silcutil/silcbuffmt.c.
3724 * Changed to auto-reconnect to check whether the remote host is
3725 router and register the re-connect timeout if it is. It used
3726 to check that whether we are normal server, but router must do
3727 auto-reconnect with another router as well. Affected file
3730 * Removed the [<key len>] option from CMODE command as the cipher
3731 name decides the key length, nowadays. See the defined ciphers
3732 from the protocol specification.
3734 * Added [<hmac>] option to the CMODE command to define the HMAC
3735 for the channel. Added SILC_CMODE_HMAC channel mode.
3737 * Added [<hmac>] option for the JOIN command so that user can
3738 select which HMAC is used to compute the MACs of the channel
3741 * Added Hmac field to the Channel Message Payload. The integrity
3742 of plaintext channel messages are now protected by computing
3743 MAC of the message and attaching the MAC to the payload. The
3744 MAC is encrypted. Now, it is clear that this causes some
3745 overhead to the size of the packet but rationale for this is that
3746 now the receiver can verify whether the channel message decrypted
3747 correctly and also when private keys are set for the channel the
3748 receiver can decrypt the packet with several keys and check from
3749 the MAC which key decrypted the message correctly.
3751 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3752 lib/silccrypt/silccipher.[ch].
3754 * Added silc_hash_len to return the digest length into the
3755 lib/silcrypt/silchash.[ch].
3757 * Rewrote parts of Silc Channel Payload interface in the
3758 lib/silccore/silcchannel.[ch]. The encode function now also
3759 encrypts the packet and parse function decrypts it.
3761 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3763 * Fixed a minor formatting bug in the SKE's key material processing.
3764 It actually might have processed the keys wrong way resulting
3767 * Redefined the mandatory HMAC algorithms and added new algorithms.
3768 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3769 and hmac-md5 truncated to 96 bits. The mandatory is now
3770 hmac-sha1-96. Rest are optional (including the one that used
3771 to be mandatory). Rationale for this is that the truncated HMAC
3772 length is sufficient from security point of view and can actually
3773 make the attack against the HMAC harder. Also, the truncated
3774 HMAC causes less overhead to the packets. See the RFC2104 for
3777 * Added new [hmac] configuration section. The SKE used to use
3778 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3779 is of course wrong. The official names that must be proposed in
3780 the SKE are the ones defined in the protocol specification
3781 (hmac-sha1-96 for example). The user can configure any hmac
3782 using any hash function configured in the [hash] section. At
3783 least, the mandatory must be configured.
3785 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3787 * Added HMAC list to the SKE proposal list. It has now both
3788 hash algorithm list and HMAC list. This makes the protocol
3789 incompatible with previous versions. The SKE now seems to work
3790 the way it is supposed to work, for the first time actually.
3792 * Defined plain Hash algorithms to the protocol specification.
3795 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3797 * Implemented support for key agreement packets into the server.
3798 Added functions silc_server_key_agreement and
3799 silc_server_send_key_agreement. Other than these functions,
3800 server has nothing to do with this packet.
3802 * Added support for private message key packets into the server.
3803 Added functions silc_server_private_message_key and
3804 silc_server_send_private_message_key.
3808 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3809 called in the protocol's final callback instead in the END
3810 protocol state. This makes a little more sense and in the same
3811 time in client we can use the same protocol routines for normal
3812 key exchange and to key agreement packet handling as well.
3814 * Added to both client's and server's KE protocol context the
3815 SilcSKEKeyMaterial pointer to save the key material. We will
3816 bring the key material to the protocol's final callback by doing
3817 this. The final callback must free the key material.
3819 * Added SKE's packet_send callback into client's KE protocol
3820 context so that the caller can choose what packet sending function
3821 is used. This way we can use different packet sending when
3822 doing normal SKE when doing key agreement packet handling (in
3823 the key agreement packet handling we do not want to encrypt
3826 * Implemented the responder side of the key agreement routines
3827 in the client. The client can now bind to specified port and
3828 accept incoming key negotiation. The key material is passed
3829 to the application after the protocol is over.
3831 * Implemented the processing of incoming Key Agreement packet
3832 in the client. Added function silc_client_key_agreement to
3835 * Implemented the intiator side of the key agreement routines
3836 in the client. The client can now initiate key agreement with
3837 another remote client. The key material is passed to the
3838 application after the protocol is over.
3840 * Created client_keyagr.c to include all the key agreement
3843 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3844 SILC_TASK_CALLBACK except that it is not static.
3846 * Created client_notify.c and moved the Notify packet handling
3847 from the client.[ch] into that file.
3849 * Created client_prvmsg.c and moved all private message and
3850 private message key routines from the client.[ch] into that file.
3852 * Create client_channel.c and moved all channel message and
3853 channel private key routines from the client.[ch] into that file.
3855 * Changed silc_client_get_client_by_id_resolve to resolve with
3856 WHOIS command instead of IDENTIFY command, in the file
3857 lib/silclient/idlist.c.
3859 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3861 * Implemented the SKE's responder side to the Client library.
3863 * When FAILURE is received to the protocol do not trust it
3864 blindly. Register a timeout to wait whether the remote closes
3865 the connection as it should do it, only after that process the
3866 actual failure. This was changed to both client and server.
3868 * Added client_internal.h to include some of the structures
3869 there instead of client.h in lib/silcclient/.
3871 * Added function silc_task_unregister_by_callback to unregister
3872 timeouts by the callback function.
3874 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Some "Incomplete WHOIS info" errors has been appearing on the
3877 log files. Took away the entry->userinfo check from WHOIS
3878 reply sending. The entry->userinfo is now " " if client did not
3879 provide one. I thought this was fixed earlier but something
3880 is wrong still. Let's see if the error still appears.
3882 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Fixed a minor bug in the login when the channel key is
3885 re-generated in the server. It used to generate the key in
3886 wrong order and thus caused problems in the channel traffic.
3888 * Fixed a minor bug in channel key distsribution after
3889 KICK command. The key was not sent to the router even though
3892 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Added silc_ske_process_key_material_data as generic routine
3895 to process any key material as the SILC protocol dictates. The
3896 function is used by the actual SKE library but can be used by
3897 applications as well. This relates to the private message keys
3898 and the channel private keys since they must be processed the
3899 same way the normal SILC session keys. The protocol dictates
3900 this. Affected files: lib/silcske/silcske.[ch].
3902 Added also silc_ske_free_key_material to free the
3903 SilcSKEKeyMaterial structure.
3905 * Defined silc_cipher_set_key function to set the key for
3906 cipher without using the object's method function. The affected
3907 files: lib/silccrypt/silccipher.[ch].
3909 * Implemented silc silc_client_add_private_message_key,
3910 silc_client_add_private_message_key_ske,
3911 silc_client_del_private_message_key,
3912 silc_client_list_private_message_keys and
3913 silc_client_free_private_message_keys functions in the
3916 Added functions silc_client_send_private_message_key to send
3917 the Private Message Key payload and silc_client_private_message_key
3918 to handle incoming Private Message Key payload.
3920 * Added Cipher field to the Private Message Key payload to set
3921 the cipher to be used. If ignored, the default cipher defined
3922 in the SILC protocol (aes-256-cbc) is used.
3924 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3926 * Removed lib/silcclient/ops.h file.
3928 Redefined parts of the SILC Client Library API. Created new
3929 file silcapi.h that deprecates the ops.h file and defines the
3930 published Client Library API. Defined also private message key
3931 API and channel private key API into the file.
3933 This is the file that the application must include from the
3934 SILC Client Library. Other files need not be included by
3935 the application anymore.
3937 * Added new key_agreement client operation callback and also
3938 defined the Key Agreement library API for the application.
3940 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3942 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3943 is used by clients to request key negotiation between another
3944 client in the SILC network. If the negotiation is started it
3945 is performed using the SKE protocol. The result of the
3946 negotiation, the secret key material, can be used for example
3947 as private message key.
3949 Implemented the Key Agreement payload into the files
3950 lib/silccore/silauth.[ch].
3952 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Redefined ciphers for the SILC protocol. Added some new ciphers
3955 and defined the key lengths for the algorithms. Changed the
3956 code accordingly. The default key length is now 256 bits.
3958 * Fixed SKE key distribution function silc_ske_process_key_material
3959 when the key length is more than 128 bits. The default key
3960 length in SILC is now 256 bits.
3962 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3963 to indicate unsupported algorithm.
3965 * Renamed rijndael.c to aes.c and all functions as well.
3967 * Fixed a long standing channel key setting bug in client library.
3968 Weird that it has never surfaced before.
3970 * Fixed bug in channel deletion. If the entire channel is removed
3971 then it must also delete the references of the channel entry
3972 from the client's channel list as the client's channel entry and
3973 the channel's client entry share same memory.
3975 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Implemented CONNECT and SHUTDOWN commands in the client.
3979 * Implemented CLOSE command to the client.
3981 * Added the function silc_idlist_find_server_by_name into the
3982 files silcd/idlist.[ch].
3984 Added the function silc_idlist_find_server_by_conn into the
3985 files silcd/idlist.[ch].
3987 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3989 * DIE command was renamed to SHUTDOWN. Updated the both code
3992 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3993 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3995 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3998 * Added function silc_server_create_connection function to create
3999 connection to remote router. My server implementation actually
4000 does not allow router to connect to normal server (it expects
4001 that normal server always initiates the connection to the router)
4002 so the CONNECT command is only good for connecting to another
4005 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4008 or some other client was kicked from the channel.
4010 Implemented the handling of the notify type to both client
4013 Implemented silc_server_send_notify_kicked to send the KICKED
4014 notify. It is used to send it to the server's primary router.
4016 * Implemented the KICK command into server and client.
4018 * Added `query' argument to the silc_idlist_get_client function
4019 to indicate whether to query the client from server or not if
4022 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4023 to indicate that the client is not channel founder.
4027 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Removed the rng context from SilcPacketContext structure and
4030 changed that the packet routine uses the Global RNG API.
4032 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4034 * Added support for quit message that client can "leave" on the
4035 channel when it quits the SILC. It is ditributed inside the
4036 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4038 Added silc_server_free_client_data that will take the
4039 signoff message as argument.
4041 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4043 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Updated parts of the protocol specification to keep it up
4048 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4050 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4051 payloads in one packet.
4053 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4054 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4055 use now the new List flag.
4057 * Also deprecated the following packet types: REPLACE_ID,
4058 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4060 * Added list support for Notify packet in server.
4062 * Added silc_server_send_notify_channel_change to send the
4063 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4064 the silc_server_send_replace_id.
4066 * Added silc_server_send_notify_nick_change to send the
4067 NICK_CHANGE notify type. Deprecates the function
4068 silc_server_send_replace_id.
4070 * Added silc_server_send_notify_join to send the JOIN notify type.
4071 Deprecates the function silc_server_send_new_channel_user.
4073 * Added silc_server_send_notify_leave to send LEAVE notify type.
4074 Deprecates the function silc_server_send_remove_channel_user.
4076 * Added silc_server_send_notify_cmode and
4077 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4078 types. Deprecates the silc_server_send_set_mode function.
4080 * Added SERVER_SIGNOFF notify type to indicate that server has
4081 quit. This means that all clients on the channel from that
4082 server will drop. This can be also used when netsplit happens.
4084 Deprecated REMOVE_ID packet type since it is not needed anymore
4087 Added silc_server_send_notify_server_signoff to send the
4088 SERVER_SIGNOFF notify type. Deprecates the function
4089 silc_server_send_remove_id.
4091 Added also silc_server_send_notify_signoff to send the
4092 SIGNOFF notify type.
4094 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4095 SILC protocol from this day on. Changed the protocol
4096 specification as well.
4098 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4099 notify type. It is used between routers to notify about
4100 topic changes on a channel.
4102 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4105 * Partly updated the protocol specification to comply with the
4106 changes now made. It is still though a bit outdated.
4108 * The JOIN notify type now takes one extra argument <Channel ID>.
4109 The packet used to be destined to the channel but now the
4110 JOIN type may be sent as list thus it is impossible to
4111 destine it to any specific channel. By adding this argument
4112 it is again possible.
4114 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Added CREDITS file. The CHANGES and CREDITS file will appear
4117 in the distribution as well.
4119 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4122 types in the server's silcd/packet_receive.c.
4124 * Implemented CMODE and CUMODE to work in router environment.
4126 * Fixed minor encoding and decoding buglet from the
4127 lib/silccore/silcmode.c.
4129 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4132 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4134 * Changed all SilcConfigServer* and silc_config_server* to
4135 SilcServerConfig* and silc_server_config*, respectively.
4138 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Associated the ID (client or server ID) to the Authentication
4141 Payload to avoid any possibility of forging. Updated the
4142 protocol specification and the code accordingly.
4144 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4146 * The RSA key length is now save to the RsaKey context in the
4147 key generation process in lib/silccrypt/rsa.c. The key length
4148 is now used to figure out the maximum size of the block allowed
4149 to be encrypted/signed.
4151 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4152 is equivalent to the silc_mp_mp2bin but does not allocate any
4155 * Changed silc_mp_mp2bin API to take length argument. If it is
4156 non-zero then the buffer is allocated that large. If zero, then
4157 the size is approximated using silc_mp_sizeinbase, which however
4160 * Created Global RNG API which is global RNG that application can
4161 initialize. After initializing, any routine anywhere in the
4162 code (including library) can use RNG without allocating a new
4163 RNG object. This was done to allow this sort of use of the
4164 RNG in code that has no chance to allocate RNG object. All
4165 applications currently allocate this and many routines in the
4166 library use this. Affected file lib/silccrypt/silcrng.[ch].
4168 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4169 it to use the Global RNG API.
4171 * Defined Authentication Payload into protocol specification that
4172 is used during SILC session to authenticate entities. It is
4173 used for example by client to authenticate itself to the server
4174 to obtain server operator privileges.
4176 Implemented this payload into the lib/silccore/silcauth.[ch].
4177 Implemented also routines for public key based authentication
4178 as the new protocol specification dictates.
4180 Moved definitions of different authentication methods from
4181 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4183 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4184 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4185 silc_pkcs_verify_with_hash functions into the file
4186 lib/silccrypt/silcpkcs.[ch].
4188 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * The client entry's userinfo pointer must be always valid.
4191 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4192 will fail since it requires the userinfo. Now, the userinfo
4193 is allocated as "" if actual userinfo does not exist. Actually,
4194 it must exist and it is totally Ok to drop client connections
4195 that does not announce the userinfo. However, we will make
4196 this workaround for now.
4198 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4199 to return the remote port by socket.
4201 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4204 SILC_SERVER_PENDING_EXEC and added an new macro
4205 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4206 data or when error occurs while processing the pending command.
4208 Added new argument `destructor' into silc_server_command_pending
4209 and to the SilcServerCommandPending object. This destructor is
4210 now called after calling the pending callback or if error occurs
4211 immediately. If error occurs the actual pending callback won't
4212 be called at all - only the destructor. The destructor may be
4213 NULL if destructor is not needed.
4215 All this applies for client library code as well. Similar
4216 changes were made there as well for the pending commands.
4218 In the client, the application must now allocate the
4219 SilcClientCommandContext with the silc_client_command_alloc
4222 * Added reference counter to the SilcServerCommandContext. Added
4223 function silc_server_command_alloc and silc_server_command_dup
4226 Same type of functions added to the client library for the same
4229 * Removed the cmd_ident from IDListData away since it is now
4230 global for all connections. It is the command identifier used
4231 in command sending and with pending commands. The affected file
4234 * Added reference counter to the SilcSocketConnection objecet to
4235 indicate the usage count of the object. The object won't be
4236 freed untill the reference counter hits zero. Currently only
4237 server uses this, and client ignores it. The client must be
4238 set to use this too later. The affected files are
4239 lib/silccore/silcsockconn.[ch]. Added also the function
4240 silc_socket_dup to increase the reference counter.
4242 This was mainly added because it is possible that the socket
4243 is removed underneath of pending command or other async
4244 operation. Now it won't be free'd and proper DISCONNECTING
4245 flags, etc. can be set to avoid sending data to connection that
4246 is not valid anymore.
4248 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4249 the connection. After that it sets SILC_SET_DISCONNECTED.
4250 It is, however, possible that the socket data is not still freed.
4251 The silc_server_packet_process now checks that data is not
4252 read or written to connection that is DISCONNECTED. The socket
4253 get's freed when the reference counter hits zero.
4255 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Changed the client operation API: channel_message operation's
4258 `sender' is now the client entry of the sender, not the nickname
4259 and the `channel' is the channel entry, not the channel name.
4261 In the private_message operation the `sender' is now also the
4262 client entry of the sender not the nickname.
4264 Affected file is lib/silcclient/ops.h and all applications
4265 using the client operations.
4267 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Moved the calling of ops->connect() from connect_to_server_final
4270 into receive_new_id functin since that is the point when the
4271 client is actually allowed to send traffic to network. The
4272 affected file is lib/silcclient/client.c.
4274 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4277 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4278 (if needs broadcasting) instead of broadcasting the packets one
4279 by one which would make a burst in the network traffic.
4281 * Added `broadcast' argument to the functions in silcd/server.[ch]
4282 silc_server_create_new_channel[_with_id] to indicate whether
4283 to send New Channel packet to primary router.
4285 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added new function into the silcd/server.[ch] files:
4288 silc_server_create_new_channel_with_id to create new channel with
4289 already existing Channel ID.
4291 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4292 lib/silccore/silcpacket.h. This packet is used t send list of
4293 Set Mode payloads inside one packet. Server uses this to set
4294 the modes for the channels and clients on those channels, that it
4295 announced to the router when it connected to it. The protocol
4296 specification has been updated accordingly.
4298 * The silc_server_new_channel did not handle the packet coming
4299 from normal server as it normally does not send that. However,
4300 when it announces its channels it does send it. Implemented
4301 the support for that.
4303 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4304 into the file lib/silccore/id.h.
4306 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Fixed memory leaks in the functions silc_idlist_del_client,
4309 silc_idlist_del_channel and silc_idlist_del_server in the file
4310 silcd/idlist.c. All of those leaked like a sieve.
4312 * Fixed some small memory leaks in the client's function
4313 silc_client_notify_by_server.
4315 * Added functions into silcd/server.c: silc_server_announce_clients,
4316 silc_server_announce_channels and silc_server_announce_server.
4317 These functions are used by normal and router server to announce
4318 to its primary router about clients, channels and servers (when
4319 router) that we own. This is done after we've connected to the
4322 These functions effectively implements the following packet types:
4323 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4324 and SILC_PACKET_NEW_ID_LIST.
4326 * Added new functions into the silcd/packet_receive.[ch]:
4327 silc_server_new_id_list, silc_server_new_channel_list and
4328 silc_server_new_channel_user_list to handle the incoming
4329 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4331 * Added support of changing Channel ID in the function
4332 silc_server_replace_id. If the server that announces a channel
4333 to the router already exists in the router (with same name but
4334 with different Channel ID), router is responsible to send
4335 Replace ID packet to the server and force the server to change
4336 the Channel ID to the one router has.
4338 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4339 client that the Channel ID has been changed by the router. The
4340 normal server sends this to the client. Client must start using
4341 the new Channel ID as the channel's ID.
4343 Implemented handling of this new type into lib/silcclient/client.c
4344 into the function silc_client_notify_by_server.
4346 * Added new function silc_idlist_replace_channel_id into the files
4347 silcd/idlist.[ch] to replace the Channel ID.
4349 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Call silc_server_command_identify_check always when processing
4352 the IDENTIFY command in silcd/command.c
4354 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4357 send keepalive packets. The packet can be sent by clients,
4358 servers and routers.
4360 Added function silc_socket_set_heartbeat into the file
4361 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4362 If not set, the heartbeat is not performed. The actual
4363 heartbeat is implemented in the low level socket connection
4364 library. However, application is responsible of actually
4367 Added silc_server_send_heartbeat to send the actual heartbeat
4368 packet into silcd/packet_send.[ch]. Server now performs
4369 keepalive with all connections.
4371 * Added silc_task_get_first function into lib/silcutil/silctask.c
4372 to return the timeout task with shortest timeout. There was a bug
4373 in task unregistration that caused problems. TODO has been
4374 updated to include that task system must be rewritten.
4376 * The client library will now resolve the client information when
4377 receiving JOIN notify from server for client that we know but
4378 have incomplete information.
4380 * Rewrote parts of silc_server_remove_from_channels and
4381 silc_server_remove_from_one_channel as they did not remove the
4382 channel in some circumstances even though they should've.
4384 * Encryption problem encountered in server:
4386 The LEAVE command used to send the Channel Key packet to the
4387 router immediately after generating it. However, the code
4388 had earlier sent Remove Channel user packet but not immediately,
4389 ie. it was put to queue. The order of packets in the router
4390 was that Channel Key packet was first and Remove Channel User
4391 packet was second, even though they were encrypted in the
4392 reverse order. For this reason, MAC check failed. Now, this
4393 is fixed by not sending the Channel Key packet immediately but
4394 putting it to queue. However, this is more fundamental problem:
4395 packets that are in queue should actually not be encrypted
4396 because packets that are sent immediately gets encrypted
4397 actually with wrong IV (and thus MAC check fails). So, packets
4398 that are in queue should be encrypted when they are sent to
4399 the wire and not when they put to the queue.
4401 However, the problem is that the current system has not been
4402 designed to work that way. Instead, the packet is encrypted
4403 as soon as possible and left to the queue. The queue is then
4404 just purged into wire. There won't be any fixes for this
4405 any time soon. So, the current semantic for packet sending
4408 o If you send packet to remote host and do not force the send
4409 (the packet will be in queue) then all subsequent packets to the
4410 same remote host must also be put to the queue. Only after the
4411 queue has been purged is it safe again to force the packet
4414 o If you send all packets immediately then it safe to send
4415 any of subsequent packets through the queue, however, after
4416 the first packet is put to queue then any subsequent packets
4417 must also be put to the queue.
4419 Follow these rules and everything works fine.
4421 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Added new function silc_server_remove_clients_by_server to
4424 remove all client entries from ID list when the server connection
4425 is lost. In this case it is also important to invalidate all
4426 client entires as they hold the invalid server entry. This
4427 fixes fatal bug when server has lost connection and will reconnect
4430 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Made some sanity checks to silc_server_daemonise like to check
4433 whether the requested user and group actually exists.
4435 * Added sanity check to SKE's silc_ske_responder_finish to check
4436 that the public and private key actually is valid.
4438 * Invalidate the client's nickname when receiving Replace ID
4439 packet and the Client ID is being replaced. This means that the
4440 server will query the nickname if someone needs it (client)
4443 * Sort the ID Cache in client library when the ID Cache data
4444 has changed (needs sorting).
4446 * Do not allow for SILC client to create several connections to
4447 several servers. The client does not support windows right now
4448 and generating multiple connections causes weird behaviour.
4450 Irssi-silc client does support windows and can handle several
4451 connections without problems, see: www.irssi.org and SILC plugin.
4453 * Fixed some places where client was added to the IDList. The
4454 rule of thumb is following (in order to get everything right):
4455 If the client is directly connected local client then the
4456 `connection' argument must be set and `router' argument must be
4457 NULL to silc_idlist_add_client function. If the client is not
4458 directly connected client then the `router' argument must
4459 bet set and the `connection' argument must be NULL to the
4460 silc_idlist_add_client function.
4462 * The funtion silc_server_packet_send_local_channel actually did
4463 not check whether the client was locally connected or not. It
4464 does that now. Fixed a bug related to LEAVE command.
4466 * Fixed Remove Channel User payload parsing bug in server's
4467 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4469 * The server's silc_server_save_channel_key now checks also the
4470 global ID list for the channel as it might not be in the local
4471 list. Fixed a bug related to LEAVE command.
4473 * Is this the end of the [<unknown>] buglet that has been lurking
4474 around for a long time? A little for loop fix in server's
4475 silc_server_command_whois_parse that is used by both IDENTIFY
4476 and WHOIS command. At least, this was a clear bug and a cause
4477 of one type of [<unknown>] buglet.
4479 * WHOIS and IDENTIFY commands call the function
4480 silc_server_command_[whois/identify]_check function even if
4481 we are not router server.
4483 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Added --with-gmp configuration option. If set the GMP
4486 is always compiled in the SILC source tree. If not set then
4487 it is checked whether the system has the GMP3 installed. If
4488 it has then the GMP won't be compiled (the system's headers
4489 and library is used), if it doesn't have it then the GMP is
4490 compiled in the SILC source tree.
4492 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Changed RSA private exponent generation to what PKCS #1
4495 suggests. We try to find the smallest possible d by doing
4496 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4497 not security fix but optimization.
4499 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Added new config entry [Identity] to fork the server and run
4502 it as specific user and group. A patch from Bostik.
4504 * Imported Dotconf configuration library into lib/dotconf.
4505 This will be used to create the SILC configuration files later.
4506 It will appear in the distsribution after this commit.
4508 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * A big code auditing weekend happening. Auditing code for
4511 obvious mistakes, bugs and errors. Also, removing any code
4514 Removed files for being obsolete:
4516 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4517 inline in the file lib/silcutil/silcbuffer.h)
4519 o lib/silcutil/silcbufutil.c (the header has inline versions)
4521 Changed code to fix possible error conditions:
4523 o The buffer formatting routines now check that the destination
4524 buffer really has enough space to add the data. This applies for
4525 both buffer formatting and unformatting
4526 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4527 unformatting was changed to accomodate following rules:
4528 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4529 sent to the function while XXX_*STRING will not allocate or copy
4530 the data into the buffer. Instead it sets the pointer from the
4531 buffer into the pointer sent as argument (XXX_*STRING used to
4532 require that the pointer must be allocated already). This change
4533 makes this whole thing a bit more consistent and more optimized
4534 (note that the data returned in the unformatting with XXX_*STRING
4535 must not be freed now). The routines return now -1 on error.
4537 o Tried to find all code that use buffer_format and buffer_unformat
4538 and added return value checking to prevent formatting and
4539 especially unformatting errors and possible subsequent fatal
4542 o Changed ske->x and ske->KEY to mallocated pointers in
4543 lib/silcske/silcske.h. Fixed possible data and memory leak.
4545 o Added return value checking to all *_parse* functions. Fixed
4546 many memory leaks as well.
4548 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4549 so that buffer overflows would not happen. All code now also
4550 checks the return value as it can fail.
4552 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Added reconnection support to server if the normal server looses
4555 its connection to the router (for example if router is rebooted).
4556 The server performs normal reconnection strategy implemented
4557 to the server. Affected file silcd/server.c.
4559 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Added new packet type SILC_PACKET_SET_MODE that is used to
4562 distribute the information about changed modes (for clients,
4563 channels and clients channel modes) to all routers in the
4564 network. Updated the protocol specification accordingly.
4566 Added functions into silcd/packet_send.c and
4567 silcd/packet_receive.c: silc_server_send_set_mode,
4568 silc_server_set_mode.
4570 Added new files silcmode.[ch] into lib/silccore that implements
4571 the encoding and decoding of Set Mode Payload. Added new type
4572 SilcSetModePayload. Moved the definitions of different modes
4573 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4575 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4577 * Oops, a little mistake in server's connection authentication
4578 protocol. The protocol is not ended with FAILURE but with
4579 SUCCESS if the authentication is Ok. :) Affected file is
4582 * Implemented NICK_CHANGE notify handling in server in the file
4583 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4584 the local clients on the channel. After the changing nickname
4585 in router environment snhould work and the [<unknown>] nickname
4586 should appear no more.
4588 The silc_server_replace_id function that receives the Replace ID
4589 payload now sends the NICK_CHANGE notify type also in the file
4590 silcd/packet_receive.c
4592 * Changed WHOIS and IDENTIFY command to support the maximum amount
4593 of arguments defined in protocol specs (3328 arguments). This
4594 fixed a bug that caused problems when there were more than three
4597 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Added extra parameter, command identifier, to the
4600 silc_client_send_command so that explicit command identifier
4603 Changed that ID list routines uses specific command identifier
4604 when sending WHOIS/IDENTIFY requests to the server so that they
4605 can be identified when the reply comes back.
4607 Affected files lib/silcclient/command.[ch],
4608 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4610 * Added `sender' argument to silc_server_packet_send_to_channel
4611 to indicaet the sender who originally sent the packet to us
4612 that we are now re-sending. Ignored if NULL. Affected file
4613 silcd/packet_send.[ch].
4615 * Added some server statistics support in silcd/server_internal.h
4616 SilcServerStatistics structure and around the server code. Also
4617 send some nice statistics information when client is connecting
4620 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * Fixed channel ID decoding in server's JOIN command reply in
4623 silcd/command_reply.c
4625 * Fixed braodcasting of replace ID payload to not to send it if
4626 we are standalone server in silcd/packet_receive.c.
4628 * Fixed all channel message sending routines to not to send
4629 packets to clients that has router set, since they are routed
4630 separately in the same function earlier. Affects file
4631 silcd/packet_send.c and all channel packet sending functions.
4633 * In USERS reply, res_argv[i] are not allocated, the table
4634 is allocated. Thus changed that free the table, not its
4637 * In server's whois_check and identify_check if the client is
4638 locally connected do not send any WHOIS commands - they are not
4641 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Fixed some minor bugs in client when sending WHOIS command. The
4644 arguments was in wrong order.
4646 * Removed statis function add_to_channel from server in
4647 silcd/command.c that was previously used with the joining but
4650 * Tested USERS command in router environment successfully with two
4651 routers, two servers and two clients.
4653 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Reorganized the USERS command and command reply in client library
4656 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4657 When the command is given by user we register a pending command
4658 callback that will reprocess the command after the reply has been
4659 received from the server. When reprocessing the packet we then
4660 display the information. Thus, the USERS information is displayed
4661 now in the command callback instead of in the command reply
4662 callback. The processing of the command is same as previously
4663 when server has sent the command reply in the JOINing process.
4665 * Added to USERS command in silcd/command_reply.c to join the client,
4666 we didn't use to know about, to the channel after we've created
4667 a client entry for it. Also, for clienet we did know already still
4668 check whether it is on the channel or not and add it if not.
4670 * Removed silc_server_command_join_notify as the function and its
4673 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4675 * Changed the client's pending command handling to the same as the
4676 server's pending command handling. It is also now possible to
4677 execute command reply functions from other command reply
4678 function as the function callbacks for commands and command
4679 replies are one and same. The pending commands are not static
4680 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4681 in client connection context. Thus, pending commands are server
4682 connection specific as it is convenient.
4684 Changed the function silc_client_command_pending and
4685 silc_client_command_pending_del and added new function
4686 silc_client_command_pending_check. Removed the
4687 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4690 * Added cmd_ident, current command identifier, to the client
4691 connection context in lib/silcclient/client.h to keep track on
4692 command identifiers used in command sending. Client's command reply
4693 function handling now supports the mandatory command identifiers.
4695 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4696 funtions in client to fully support pending command callbacks.
4698 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4699 as one of the arguments to the application in the command reply
4702 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4703 before first releasing SILC but came back. Now it is removed again
4704 and should come back nomore. The FORWARDED flag was used only
4705 by the JOINing procedure by forwarding the command packet to router.
4706 Now, the JOINing procedure has been changed to more generic (due
4707 to various router environment issues) and FORWARDED is not needed
4708 anymore for anything. The protocol specification is yet to be
4711 Now, removed silc_server_packet_forward from server and the flag
4712 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4714 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Renamed NAMES command to USERS command. The NAMES was named that
4717 due to historical reasons. Now it is renamed. Also, rewrote
4718 parts of the USERS command. The nickname list is not sent anymore
4719 by the server. Only Client ID and mode lists are sent in the USERS
4720 command. Changed this also to the protocol specification.
4722 The client now resolves the names and stuff after it receives
4723 the USERS list from the server when joining to the channel.
4725 * WHOIS and IDENTIFY commands has been changed to support multiple
4726 Client ID's per command. One can now search for multiple users
4727 in the network by sending only one WHOIS or IDENTIFY command.
4728 Changed the code and the protocol specifications.
4730 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4731 uses silc_server_command_whois_parse to parse the request. */
4733 * If normal server, do not parse the WHOIS and IDENTIFY requests
4734 before sending it to the router. Saves some time.
4736 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4738 * Fixed JOIN command on client library. Wrong number of arguments
4739 used to crash the client.
4741 * Added silc_server_channel_has_global function to check whether
4742 channel has global users or not.
4744 * Added silc_server_channel_has_local function to check whether channel
4745 has locally connected clients on the channel.
4747 * The silc_server_remove_from_one_channel now checks whether the
4748 channel has global users or not after given client was removed from
4749 the channel. It also checks whether the channel has local clients
4750 on the channel anymore. If it does not have then the channel entry
4751 is removed as it is not needed anymore.
4753 * The silc_server_notify now checks on JOIN notify whether the joining
4754 client is one of locally connected or global. If it is global then
4755 the channel has now global users on the channel and that is marked
4756 to the channel entry. Also, it now saves the global client to
4757 global list who is joining and JOINs it to the channel. This is
4758 for normal server, that is.
4760 Changed silc_server_send_notify_on_channel,
4761 silc_server_packet_relay_to_channel and
4762 silc_server_packet_send_to_channel check if we are normal server
4763 and client has router set (ie. global client) do not send the
4764 message to that client, as it is already routed to our router.
4766 * Implemented LEAVE notify type handling in silc_server_notify
4769 * Tested LEAVE command in router environment successfully. Tested
4770 with two routers, two servers and two clients.
4774 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4776 * Implemented SIGNOFF notify type handling in silc_server_notify
4779 * silc_server_remove_id now removes the client entry from all channels
4780 it has joined and thusly sends SIGNOFF notify type.
4782 * Rewrote the NAMES list generation in server by removing two excess
4783 loops. The lists are created now inside one loop.
4785 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * silc_server_remove_channel_user checks now also global list
4788 for channel and client.
4790 * silc_server_new_channel_user checks now both local and global
4791 list for channel and client. Fixed a bug in client id decoding.
4792 Used to decode wrong buffer.
4794 * silc_server_channel_message checks now both local and global
4795 list for channel entry.
4797 * Tested channel joining (hence JOIN) in router environment
4798 successfully. Tested with two routers, two servers and two
4801 * Tested channel message sending in router environment successfully.
4803 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Added silc_server_save_channel_key into server.[ch] to save the
4806 received channel key in Channel Key payload processing. It is
4807 also used in JOIN command reply handling.
4809 Equivalent function silc_client_save_channel_key added into
4810 client.[ch] into client library.
4812 * Changed JOIN command reply to send information whether the channel
4813 was created or not (is existing already) and the channel key
4814 payload. Changed protocol specs accordingly.
4816 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4817 the request was sent by ID and not by nickname. Crashed on
4820 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4823 now correctly save the received data.
4825 * silc_server_free_sock_user_data now notifies routers in the
4826 network about entities leaving the network.
4828 At the same time implemented functions silc_server_remove_id
4829 and silc_server_send_remove_id to receive and send REMOVE_ID
4830 packets. The packet is used to notify routers in the network
4831 about leaving entities. The ID removed will become invalid in
4834 * Added function silc_idlist_del_server into server. Removes and
4835 free's server entry from ID list.
4837 * silc_server_private_message function now checks, if we are router,
4838 that the destination ID really is valid ID, naturally.
4840 * In router when NEW_ID packet is received (for new client) the
4841 hash of the Client ID is saved in the ID Cache but the
4842 client->nickname is set to NULL, instead of putting the hash
4845 IDENTIFY command now also checks that client->nickname must be
4846 valid. If it is not if will request the data from the server who
4847 owns the client. Added new function
4848 silc_server_command_identify_check.
4850 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4851 to set the command to already allocated Command Payload.
4853 * Tested private message sending in router environment with two
4854 routers, two servers and two clients. Fixed minor bugs and now
4857 * Fixed segfault from client's NAMES command. Used to crash if
4860 * Forwarded packets must not be routed even if it is not destined
4861 to the receiver. Changed server code comply with this.
4863 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Added `require_reverse_mapping' boolean value to ServerParams
4866 structure. If TRUE (not default) the server will require that
4867 the connecting host has fully qualified domain name.
4869 If the reverse mapping is not required and hostname could not be
4870 found the IP address is used as hostname.
4872 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4874 * Implemented version string checking to both client and server.
4875 The check is incomplete currently due to the abnormal version
4876 strings used in development version of SILC.
4878 * Changed all command functions in server to use the new
4881 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Changed char *data to unsigned char *data in ID Cache system to
4884 support binary data as ID Cache data. Changed code to support
4885 binary data in lib/silccore/idcache.c.
4887 * Renamed silc_server_packet_relay_command_reply to
4888 silc_server_command_reply as it is normal packet receiving
4889 function. Rewrote the function to accept command replys for
4890 servers and not only for clients.
4892 * Mark remote router always as registered server if we are connecting
4893 to it. Otherwise, commands sent by the router to us are ignored.
4895 * All ID List find routines now returns the ID Cache Entry pointer
4896 as well if requested.
4898 * WHOIS command works now in router environment, tested with two
4899 routers, two servers and two clients.
4901 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4902 in router environment (as it is almost equivalent to WHOIS) but
4903 hasn't been tested thoroughly. Added new functions:
4905 silc_server_command_identify_parse
4906 silc_server_command_identify_send_reply
4907 silc_server_command_identify_from_client
4908 silc_server_command_identify_from_server
4910 * Disabled route cache adding because adding two different ID's with
4911 same IP replaces the old cache entry thus giving wrong route.
4912 The entry->router->connection is always the fastest route anyway
4913 so route cache may not be needed. Of course, new routes maybe
4914 established after receiving the ID when the entry->router->connection
4915 might not be anymore the most optimal.
4917 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4919 * Add route cache for received ID for fast routing.
4921 * Added silc_server_packet_route to route received packet on router
4922 that is not destined to us.
4924 * Renamed silc_server_get_route to silc_server_route_get.
4926 * Added id_string and id_string_len fields into SilcServer to
4927 include encoded ServerID for fast comparing without excess
4928 encoding of the ID's.
4930 * Cleaned up WHOIS command on server side. Added following static
4933 silc_server_command_whois_parse
4934 silc_server_command_whois_check
4935 silc_server_command_whois_send_reply
4936 silc_server_command_whois_from_client
4937 silc_server_command_whois_from_server
4939 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4940 arguments in command replies. All command functions should be
4941 updated to use this macro.
4943 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Minor typo fixes on command reply handling on server.
4947 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added silc_server_command_add_to_channel internal routine to add
4950 the client to the channel after router has created the channel and
4951 sent command reply to the server.
4953 * Added generic silc_server_send_command to send any command from
4956 * Use static buffer with ID rendering instead of duplicating data.
4958 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Fixed a channel user mode bug when joining to a channel server gave
4961 everybody channel founder rights, oops.
4963 * We mark ourselves as the router of the incoming server connection
4964 if we are router ourselves. This way we can check in some packet
4965 sending functions whether it is locally connected server. For
4966 incoming router connections we put NULL.
4968 * For router sending packets locally means now always sending the
4969 packet cell wide; to local clients and local servers. For normal
4970 server sending packet locally means sending it to only local
4973 * Fixed the JOIN command to really work in router environment. If the
4974 channel is created it is always created by the router. Router is
4975 also responsible of making the initial joining to the channel,
4976 sending JOIN notify to the sending server and distributing
4977 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4978 does not exist server doesn't do anything else but forward the
4979 command to the router which performs everything.
4981 * Added silc_server_send_channel_key function to send the Channel Key
4984 * Added silc_server_create_channel_key to create new channel key. The
4985 channel key is now re-generated everytime someone joins or leaves
4986 a channel, as protocol dictates. Note: channel->key_len is the
4989 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4991 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4992 packet_receive.[ch] to separate packet sending and receiving
4993 routines. The server.[ch] now includes everything else including
4994 actual packet processing (writing and reading data) and other
4997 Renamed silc_server_private_message_send_internal to
4998 silc_server_send_private_message. The routine is still though
4999 used only to relay private messages as server does not send
5000 private messages itself.
5002 Renamed silc_server_new_channel to silc_server_create_new_channel
5003 and added new function sicl_server_new_channel that handles the
5004 incoming New Channel packet. Added also new sending function
5005 silc_server_send_new_channel to send New Channel Payload.
5007 * Added new function silc_server_notify to process incoming notify
5008 packet to the server/router. Server may then relay the notify
5009 to clients if needed.
5011 * Added new function silc_server_new_channel_user to process incoming
5012 New Channel User packet. Router will redistribute the packet and
5013 send JOIN notify to its local clients and locally connected servers
5014 if needed. Normal server will send JOIN notify to its local client
5015 on same channel when received this packet. Added also corresponding
5016 sending function silc_server_send_new_channel_user to sent the
5019 * Added boolean route argument to send_notif_to_channel and
5020 packet_send_to_channel functions to attempt to route the packet
5021 if it is TRUE and send only locally if it is FALSE.
5023 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * silc_server_replace_id now broadcasts the received replace ID
5026 packet if it is not broadcast packet already. The router must
5027 broadcast to inform other routers about changed ID.
5029 * Added backpointer to server's router into SilcServer context in
5030 silcd/server_internal.h.
5032 * Fixed silc_server_packet_broadcast to send correct broadcast
5035 * The channel key is now distributed to the local client as soon
5036 as it is received from the router (in router environment) so that
5037 no other packet may be sent for the channel until client has
5040 * silc_server_remove_channel_user now broadcasts the received
5041 Remove Channel User packet if it is not broadcast packet already.
5042 The router must broadcast to inform other routers about removed
5045 * Added users field into SilcPacketContext that is a reference count
5046 of the context. One can increase the reference count by calling
5047 silc_packet_context_dup which is now changed to just increase the
5048 reference count instead of duplicating the data. The reference
5049 count is decresed by calling silc_packet_context_free that will
5050 free the data after the reference count hits zero.
5052 For now on the packet context and everything allocated into it
5053 (including the raw packet from network) must be freed by calling
5054 the new silc_packet_context_free function. Added also new function
5055 silc_packet_context_alloc that must be used now to allocate the
5056 context. This also means that if a routine is asynchronous from
5057 silc_[client/server]_packet_parse_type the packet context must
5058 be duplicated by calling silc_packet_context_dup. Otherwise it
5059 gets free'd after silc_[client/server]_packet_parse_type returns.
5060 Also, one must remember that if packet is duplicated then its
5061 reference count must be decresed by calling the free function as
5062 many times as it was duplicated.
5064 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5065 from both client and server.
5067 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Made joining to a channel working in router environment.
5071 * Cleaned up JOIN command on server side and create function
5072 silc_server_command_join_channel internal routine to make the
5075 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Changed silc_command_pending list to SilcDList. Also, added
5078 `ident' field to SilcServerCommandPending structure to identify
5079 the reply and to call correct callback.
5081 Added silc_server_command_pending_check function to replace the
5082 corresnponding macro. The silc_command_pending list is not
5085 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5086 to set identifier to previously allocated Command Payload. It
5087 is used to set identifier for command when resending Command
5090 * Added silc_command_payload_encode_payload to encode Command
5091 Payload buffer from SilcCommandPayload structure.
5093 * Added silc_argument_payload_encode_payload to encode Argument
5094 payload buffer from SilcArgumentPayload structure.
5096 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Changed WHOIS command to support router connection on server side.
5099 The whois request is always sent to router unless the server is
5100 standalone server. After server has received the reply from the
5101 router will it send the reply to the client.
5103 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5104 broadcast received broadcast packet. The function is used only
5105 by router. The broadcast packet is always sent to the router's
5108 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5109 render given ID to printable string, for log files for example.
5111 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Made basic router to router connections working. At least they
5114 can now connect to each other but nothing really works the way
5115 they are supposed - yet.
5117 * Added new initiator token to RouterConnection configuration
5118 file in silcd/serverconfig.[ch]. It is used to tell whether we
5119 are the initiator to the remote router or whether we'll expect
5120 the other end to connect.
5122 * Moved registering of listener task to silc_server_init, hence
5123 the server starts listenning as soon as it is run, even if it
5124 does not have connections to other routers. Let's see how well
5127 * Changed default connection retry timeouts for more suitable in
5130 * Removed cipher and such arguments from silc_idlist_add_client
5131 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5132 Added new function silc_idlist_add_data to add the keys and stuff
5135 * Added SilcIDListData structure and added it to SilcClientEntry
5136 and SilcServerEntry as their first field in the structure. This
5137 way we can explicitly cast the ID entries to the SilcIDListData
5138 structure and get common data for the entries. In past, we had
5139 to first check what type of connection it is and then cast it to
5140 correct ID entry type. Now, we can directly cast the opaque
5141 pointer to the SilcIDListData (no matter what ID entry it actually
5142 is) and get the data needed.
5144 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5147 in some circumstances even if threre were timeout tasks, though not
5148 IO tasks, but tasks anyway. Now fixed.
5150 * Defined SilcServerConnection structure to hold connection specific
5151 stuff about directly connected servers and routers. The definition
5152 is currently in silcd/server_internal.h. I thought about having
5153 a bit more important role fro this struct but for now it is used
5154 only when connecting to other server (or router actually).
5156 * Added connecting retry support in server when connecting to
5157 router(s). The retry feature implement exponential backoff
5158 algorithm. Also, added SilcServerParams structure to hold default
5159 parameters for server. For now, it include these retry settings
5160 and are hard coded. After server is moded to be as Silc Server
5161 Library this structure will be more important.
5163 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5165 * Changed client librarys channel->clients table to SilcList and
5166 changed code accordingly.
5168 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Changed client's channel table to SilcList and changed code
5171 accordingly. Also changed SilcChannelClientEntry to include back-
5172 pointer to the channel so that client entry can use that structure
5173 as list as well and we have fast cross-reference to the channel.
5174 This change dramatically decreased the complexity of channel
5175 handling with client entry and vice versa (removed one extra
5176 loop when searching for channel entry from many functions).
5178 * Changed server->sim from table to SilcDList and changed code
5181 * NAMES command can now be used from user interface. It will show
5182 the user list on the channel, neatly.
5184 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5185 Code now saves realname of the user if it becomes available.
5187 * Renamed configure.in to configure.in.pre and made ./prepare
5188 script to automatically add correct version string to
5189 configure.in which it creates from configure.in.pre.
5191 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * NAMES command reply now shows users mode with the nickname when
5196 * Moved silc_client_ch[u]mode[_char] functions from
5197 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5198 place sucks, they are utility functions and should be in some
5201 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5203 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5206 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Added TRQ (efficient deque and list library) into lib/trq. This is
5211 a very good list library that is currently used in the SILC. Defined
5212 SilcList API over the library because I didn't like the API very
5213 much. See lib/trq/silclist.h for the API and examples of how to
5214 use the API. Fixed various places in the code to use the new
5215 SilcList API. The SilcList is meant for lists that has a structure
5216 already defined as a list. It is not suitable to add just some
5217 context to the list (in TRQ, the context is the list actually).
5219 So, I defined SilcDList that can be used for the purpose where
5220 predefined list structure does not exit. This can be used as
5221 such list. Now some context just can be added to the SilcDList.
5222 Currently this list is not used in the SILC just yet, though there
5223 are a lot places where this can replace dynamically allocated
5224 tables and I will fix these places, later, to use SilcDList.
5225 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5226 and use TRQ internally).
5228 Also fixed some annoying warning messages that the original TRQ
5229 code generated. Also minor changes to TRQ's Makefile.in.
5231 * Added support for querying by Client ID to both WHOIS and
5232 IDENTIFY commands into server, as required by the protocol.
5234 * Removed method function pointers from SilcBuffer structure. They
5235 weren't used to anything and just increased the context size for
5236 no good reason. This change also made silc_buffer_alloc and
5237 silc_buffer_free functions inline functions.
5239 * Disabled command flooding detection support until it's fixed so
5240 that it accepts commands in but does not execute them more than once
5243 * Added silc_net_localhost(), to return local hostname, into
5244 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5245 that must be initialized before calling silc_client_init.
5247 * Added new function: silc_server_send_notify_on_channels to send
5248 notify messages to all channels client has joined. It is assured
5249 that the message is sent only once per client.
5251 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5252 lib/silcutil/silcutil.[ch] as silc_format function. The new
5253 function is generic and is used by server as well, not only by
5254 the logging routines.
5256 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5257 the provided version string was not acceptable. Added new function:
5258 silc_ske_check_version into lib/silcske/silcske.h. The function
5259 must be implemented by the application (client or server) and it
5260 does not reside in the SKE library. The function checks the version
5261 string remote end sent.
5263 * Added back pointers (to opaque context and to SilcSocketConnection)
5264 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5266 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5267 duplicate packet context structure.
5269 * Changed `notify' client operation to send same arguments as client
5270 receives from server except for ID's. ID's are mapped to correct
5271 ID entry and that is returned. Also, if channel entry is not sent
5272 by server but the notify is for channel the channel entry is sent
5273 to application (otherwise application doesn't know that it is for
5274 channel (library gets it from packet's Destination ID)).
5276 * Added silc_client_remove_from_channels into client library to
5277 remove a client from all channels it has joined to. Used when
5278 received SIGNOFF notify from server. Added also new function
5279 silc_client_replace_from_channels to replace old ID entry with
5280 new ID entry on all channels. Used when received NICK_CHANGE
5283 * Fixed ID Cache list handling in silc_idlist_get_client in
5284 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5285 to get (or query) client by ID.
5287 * Updated TODO list.
5289 * Added connection authentication status message defined by the
5290 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5291 support for these into the code in client and server side.
5293 * Added generic function silc_client_send_command to send any command
5294 with variable argument list. Application should use this function
5295 to send commands if the command functions provided by the library
5296 does not suite for the application's user interface needs.
5298 * Added new `failure' client operation. Application is notified about
5299 received failure packet if client is executing a protocol. In this
5300 case the protocol's execution has failed.
5302 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5303 is required by the protocol.
5305 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5306 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5309 * Added status flag to SilcSKE object to indicate realtime status
5310 of the SKE protocol.
5312 * Application receives now exactly same command reply arguments as
5313 the library receives from server. However, if ID is received the
5314 corresponding ID entry is returned to the application (eg. Client
5315 ID is mapped to correct SilcClientEntry entry and that is returned).
5316 Changed command_reply client operation due to this change.
5318 * Changed all ID's in commands and in command replys as ID Payloads.
5319 Change affected both client and server side codes.
5321 All ID's sent in SILC network (with execption of ID's in SILC
5322 Packet header) are sent in ID Payload to support variable length
5325 * Server now notifies nick changes and notifies all clients on
5326 the channels about the new nickname (about the new Client ID,
5329 * Implemented CMODE command to change channel modes. Supports all
5330 channel modes defined by the protocol specs except ban and invite
5331 lists. (Also, private channel key mode is supported but support for
5332 setting private channel key in client is missing, thus, this mode
5333 has no effect on client side (except that server requires that the
5334 client uses private channel key and normal channel traffic does not
5337 Also, invite mode works per se, but INVITE command does not work
5338 yet correctly, so you can set channel as invite only channel but
5339 inviting clients to the channel does not work (it is yet to be
5340 thought what's the best way to do it).
5342 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5343 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5344 Implemented CUMODE command to change user's mode on the channel.
5345 Supports all modes defined by the protocol specs.
5347 * Added NAMES command reply to return users modes on the channel.
5349 * Removed unnecessary and slow ciphers from lib/silccrypt.
5351 * Set SO_KEEPALIVE option to connection sockets by default.
5353 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5355 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5356 redefined the Notify Payload into protocol specs.
5358 * Added silc_id_payload_parse_id to get ID directly from raw
5361 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5364 accept searching by Client ID as well.
5366 * Added support for LEAVE and SIGNOFF notify types in client library.
5368 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5369 to parse ID Payload from raw data.
5371 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Added flags parameter into silc_ske_assemble_security_properties
5374 function in lib/silcske/silcske.[ch].
5376 * Changed notify client operation to fit better for notify messages
5377 sent by server. The notify payload received from server is now
5378 passed to the application (after parsing it to SilcNotifyPayload).
5379 It is application's responsibility to retrieve the arguments
5380 from the payload and show the message the way it wants. The message
5381 sent by server is implementation specific.
5383 * Changed public keys to comply with the protocol specification.
5384 Old public keys are not supported anymore and are not compatible.
5386 * Removed nickname from Channel Payload as the latest draft removed
5387 it. The client must resolve the nickname from the NAMES command
5388 reply received when it joined the channel.
5390 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5392 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Fixed some errors in protocol specification drafts.
5396 * Created lib/silccore/silcnotify.c to implement Notify Payload
5397 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5398 generic payloads described by protocol specifications. The file
5399 includes implementations for ID Payload and Argument Payload.
5401 * Changed Command Payload implementation to use the new Argument
5402 Payload. Changed command_xxxx_payload to command_payload_xxxx
5403 to comply with SILC coding conventions.
5405 * Added suppport for Argument Payload handling in Notify Payload
5406 implementation as protocol requires it. Added the new support
5407 into server and client lib as well.
5409 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Added support for multiple nicknames on same channel. [n] is
5412 added locally to the nickname if there are more than one same
5413 nicknames on the channel.
5415 * Server now sends all nicknames that matched WHOIS request.
5416 Client also shows the list received from server.
5418 * Added TOPIC command to client side. User can now set and show
5419 current topic on channel.
5421 * Added MOTD command to client and server. Also, server sends the
5422 motd when client connects to the server.
5424 * Changed version strings to comply ISO 8601.
5426 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Fixed protocol error handling in client library. It should now
5429 cope even if the SKE fails for some reason.
5431 * Made new protocol specification drafts for submitting to IETF.
5433 * Implemented TOPIC command to server in silcd/command.c.
5435 * Added two new notify types into lib/silccore/silcnotify.h:
5436 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5437 notify nickname change and topic setting/change on a channel.
5439 * API change of command_reply operation in client library. The
5440 application gets now the status type received from server as well.
5442 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5446 * Cras fixed and optimized the packet handling even further and
5447 it should work now. Minor change to the prototype of function
5448 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5450 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added new function into lib/silcutil/silcschedule.[ch]:
5453 silc_schedule_with_fd to select() a specified fd. The function
5454 returns after timeout expires or data arrives or goes. The
5455 function is used by packet routines to wait that all data is
5456 received from network.
5458 * Fixed data reading from network in lib/silccore/silcpacket.c.
5459 The code now assures that all data is read from the fd and then
5460 continues packet processing. This was a bug fix since the code
5461 used to drop some data in some circumstances.
5463 * Added new function into lib/silcclient/client.[ch]:
5464 silc_client_start_key_exchange to start key exchange after
5465 connection has been established to server. The code internally
5466 now uses this funtion but its main purpose was to provide it
5467 for applications that perform their own connecting. After
5468 application has created a connection it merely calls this
5469 function to start the key exchange between client and server.
5470 The library takes care of everything else after that.
5472 Updated also lib/silcclient/README to explain the usage of
5475 * Do not send to application information that connection has
5476 been established. Application gets notified it by connect
5479 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Applied cras's patch to add silc_schedule_one function. The
5482 function runs scheduler once and returns.
5484 * Fixed the scheduler after cras messed it up. The timeout
5485 handling works now as it's supposed to work.
5487 * Added into lib/silccore/ silcnotify.h to include notify
5488 message types support. Changed silc_server_send_notify*
5489 functions, in server.[ch], to support those new notify types.
5490 Added the support for the notify types into client library,
5491 as well. Added new notify client operation into ops.h in
5494 * Changed silc_server_packet_send_to_channel to send normal
5495 packets instead of just channel message packets. The function
5496 is now used to send the notify packets to channels. It is not
5497 used to send channel message packets anymore, as server never
5500 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5501 va_arg()s as it seems to require it nowadays. I guess, if SILC
5502 is compiled with older va_arg() the new code should work anyway.
5504 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Splitted core library. Core library (lib/silccore) includes
5507 now only SILC protocol specific core (and common) components.
5508 Created new utility library (lib/silcutil) that includes more
5509 generic purpose stuff. The stuff for util library was taken
5510 from the old core library. This was minor and easy split.
5512 * Created SILC Client Library (lib/silcclient) that includes
5513 implementation of the SILC client without user interface. This
5514 was major move from silc/ directory. The code has been changed
5515 so that it is transparent towards the user interface. The
5516 silc/ directory includes now the same user interface as before
5517 and it uses the new client library. Read lib/silcclient/README.
5518 Basicly, the client library performs everything else related
5519 to SILC except user interface handling. Also, configuration
5520 files are considered to be part of user interface and library
5521 does not handle them.
5523 This change also changed a lot of structures, function naming etc.
5524 Most important change was that SilcClientWindow object was
5525 renamed to SilcClientConnection in the client library. Created
5526 also new file lib/silcclient/ops.h. Also added new files
5527 silc/local_command.[ch] and silc/client_ops.[ch].
5529 All these changes were made to make it easier for user interface
5530 designers to create what ever user interface for the SILC client
5533 It is also expected that the server will be moved to lib
5534 directory as well and SILC Server Library will be created;
5535 sometimes in the future.
5537 * Removed Local commands from lib/silccore/silccommand.h as
5538 they are application specific and new client library does not
5539 handle any of those anymore.
5541 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5542 old client implementation in silc/.
5544 * Added support for callback functions in SILC_LOG_* macros.
5545 Application can now set its own callbacks that will be called
5546 instead of using the default functions that will always print
5547 the debug messages to stderr (or stdout). Also, debugging can
5548 now be disabled by setting silc_debug to FALSE and re-enabled by
5549 setting it to TRUE. Note, that logging will still work even
5550 if debugging is disabled.
5552 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5553 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5554 silc_log_reset_debug_callbacks.
5556 * To enable debugging in silc client one must give now -d
5557 option on command line.
5559 * Changed silc_schedule_init to automatically allocate task queues
5560 if they are not allocated before calling it.
5562 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Added GMP 3.1 into math library.
5566 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5569 a channel in SILC network. The packet is used by servers and
5570 routers to notify other routers that user has left a channel.
5571 This little feature was missing until now. Added the feature
5572 to protocol specification as well.
5574 Added functions: silc_server_send_remove_channel_user and
5575 silc_server_remove_channel_user into server.[ch].
5577 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5578 lib/silccore/silcpacket.h. However, they are not implemented
5581 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Fixed joining to a channel and sending channel messages
5584 between server and router. The channel message sending should
5585 now work inside a cell.
5587 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5589 * Fixed the private message sending between server and router.
5590 The private message sending should now work inside a cell.
5592 * Added silc_server_replace_id into server.[ch] to replace
5593 existing ID in the SILC network.
5595 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5596 and silc_idlist_replace_server_id into idlist.[ch] in server.
5598 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Fixed the server to server connections. Server can again now
5601 connect to router. Router to router connections probably does
5604 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Added dynamic protocol registering support. Now protocols can
5607 registered and unregistered on the fly. Patch by cras.
5609 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added lib/contrib directory to hold routines that some platforms
5612 don't have but are needed by SILC.
5614 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5615 into lin/contrib to provide getopt() and getopt_long() for
5616 those who don't have it.
5618 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added AWAY command to client. When away message is set and
5621 client receives a private message packet the client automatically
5622 replies to the sender with the away message.
5624 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5625 bug seemed to be the cause of recent problems when compiling
5628 * Added version detection support to SKE protocol specification
5629 and added the new changes to the SKE implementation as well.
5630 There were other minor changes in the SKE protocol as well.
5632 Many changes in lib/silcske/silcske.[ch] and in
5633 lib/silcske/payload.[ch].
5635 * Added ^U functionality, clear input line. Patch from cras.
5637 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Mainly small bugfixes on core library. Fixed some debugging
5640 logging and buffer overflow in silclog.c.
5642 * Updated config.sub and config.guess on the distribution tree.
5644 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Added command lagging support in server. Client may execute
5647 commands now only once in two seconds.
5649 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Optimized packet reception. MAC computation and checking is now
5652 also more optimized. A lot previously duplicated code is now
5653 used as generic by both client and server.
5655 * Fixed key pair generation in clientutil.c
5657 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added into lib/silccore/silcbufutil.[ch] new function;
5660 silc_buffer_realloc.
5662 * Moved generic packet sending/encryption functions to
5663 lib/silccore/silcpacket.[ch] from client and server. Some
5664 rewriting of the functions.
5666 * Moved all generic packet reception/decryption functions to
5667 lib/silccore/silcpacket.[ch] from client and server. The
5668 packet processing is now much cleaner in both client and server.
5669 These were major changes in both client and server.
5671 * Created many common functions in server to do packet sending.
5672 Previously code were duplicated a lot, this has been removed
5675 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Rewrote major parts of the ID cache system. Don't know
5678 whether it is better now or not but at least the API is more
5681 * Major rewrite on ID cache stuff on client because of the ID
5682 cache API changes. Added idlist.c to client.
5684 * Also major rewrite on ID cache stuff on server as well.
5685 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5686 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5687 in hand, instead they are all put into the ID cache system now.
5688 All server_idlist_* routines uses ID cache now instead of
5689 traversing its own lists (those lists does not exist anymore).
5690 SilcIDList though still exists. Also, SilcXXXEntry's are
5693 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Finally made the SKE implementation compliant to the protocol
5696 specification. All mp integers are now binary encoded as
5697 opposed being HEX encoded.
5699 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5702 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5703 functions: silc_[encode/decode]_pem. Also added function
5704 silc_encode_pem_file to PEM encode with newlines ('\n') for
5707 * SILC public keys are now encoded either PEM or binary. Same
5708 option is for private keys as well. By default private keys
5709 are binary encoded and public keys PEM encoded. Silly HEX
5710 encoding were removed.
5712 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5713 function to create fingerprints.
5715 * Fixed a bug in SHA1; does not change the original data anymore.
5717 * Partly implemented INFO command on client and server side.
5718 Fixed CLEAR command. Changes to SERVER command; show current
5719 server(s) when giving command without arguments. Added
5720 VERSION command to client.
5722 * Added check to server that unregistered connections cannot
5723 execute commands (unless it is specificly allowed).
5725 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed screen refresh.
5729 * Fixed channel joining bug from client. On some circumstances
5730 client tried to join to a channel it had already joined.
5732 * Added public key verification process into client's protocol.c.
5733 The client now verifies the public key from user and saves
5734 it into ~./silc/serverkeys/ directory.
5736 Added into: clientutil.[ch]: silc_client_verify_server_key.
5738 * Changed SKE protocol's silc_ske_initiator_finish function
5739 to accept callback function that verifies the received public
5740 key. Removed old silc_ske_verify_public_key function.
5742 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5745 silc_pkcs_private_key[_data]_set.
5747 * Made the password and public authentication more cleaner in
5748 server's protocol.c.
5750 * Removed historic and obsolete protocol `channel_auth' from
5751 both client and server.
5753 * Removed wrong way of sending command status messages from
5754 server to client in server's command.c. The old way violated
5755 protocol specification.
5757 Changes to silccore/silccommand.[ch]: removed
5758 silc_command_encode_status_payload -> not needed anymore,
5759 changed silc_command_encode_payload_va to accept extra
5760 argument on variable argument list. The argument type must
5761 now be provided to the function. Also, added new function:
5762 silc_command_encode_reply_payload_va which is same as
5763 normal command_encode_payload_va except command status type
5764 is provided as extra argument.
5766 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Added ~./silc directory handling. The directory includes the
5769 public and private keys for the client.
5771 Added silc_client_check_silc_dir, silc_client_create_identifier
5772 and silc_client_load_keys.
5774 * Implemented SILC protocol compliant public key. Added public
5775 and private key saving to and loading from files.
5777 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5778 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5779 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5780 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5781 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5783 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5784 silc_pkcs_load_[public/private]_key.
5786 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Added silc_server_get_route (route.[ch]) to get connection
5789 data for the fastest route for given ID.
5791 * Implemented INVITE command on client and server. The command
5792 were re-defined in the SILC Protocol Specification and the
5793 implementation now complies with the specification.
5795 * Implemented PING command on client and server.
5797 * Implemented NAMES command on client and server. The server side
5798 supports currently only normal server not router server yet.
5799 Some changes to NAMES definition in SILC protocol specification.
5801 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Implemented LEAVE command on client and server.
5805 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5806 again. This change was made to the protocol as well. Server
5807 should not violate the protocol specification anymore.
5809 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5812 was tested. SOCKS4 was not but should work anyway.
