69 during SERVER_SIGNOFF, but invalidate it. This way we
70 preserve the WHOWAS info for the client. Affected file
73 * Fixed SERVER_SIGNOFF notify handling in the server. The
74 server is now able to process incoming SERVER_SIGNOFF notify
75 for a server that it doesn't even know about. It will remove
76 the clients provided in the notify. Affected file
77 silcd/packet_receive.c.
79 * Check for partial packet in data queue after every packet that
80 was found from the queue. Return and wait for more data if

114 now in server, to optimize packet processing. Affected file
117 * Include files are installed now only in Toolkit distribution
118 if make install is given. Affected files: all Makefile.am's.
120 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
122 * Assure that silc_client_notify_by_server_resolve does not
123 resolve the client information multiple times. If it cannot
124 be found by the first it cannot be found at all. Affected
125 file lib/silcclient/client_notify.c.
127 * Fixed WHOWAS command reply calling. Affected file
128 lib/silcclient/command_reply.c.
130 * Removed all references to silc_idlist_get_client from the
131 Irssi SILC client since that call is internal call used by
132 the library. The Irssi SILC client will use now client
133 retrieval functions found in silcapi.h.
135 * Fixed a bug in resolving nickname info before sending
136 private message. It used freed memory. Affected file
137 irssi/src/silc/core/silc-servers.c.
139 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

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

202 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
204 * Resolve the client info when received private message or
205 channel message for a client which nickname we don't know.
206 Affected files lib/silcclient/client_prvmsg.c and
207 lib/silcclient/client_channel.c.
209 * Do not crash in /KEY if client is not connected. Affected
210 file irssi/src/silc/core/silc-channels.c.
212 * Added SilcClientStatus field to the SilcClientEntry in the

215 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
216 is incomplete and is being resolved, it won't be resolved
219 Make sure also that USERS command reply does not resolve
220 twice information. Affected file is
221 lib/silcclient/command_reply.c.
223 Make sure that silc_client_get_clients_by_list does not
224 resolve twice same information.

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

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

379 in upstream or downstream. Affected file is
382 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
384 * Wrote the definition of the backup resuming protocol to the
385 protocol specification.
387 * Removed one redundant channel key generation from normal
388 server during joining procedure. Removed one redundant
389 channel key sending from server to router during joining
390 procedure. Affected file silcd/command.c.
392 * Made minor bugfixes to the backup router resuming protocol.
393 Affected file silcd/server_backup.c, server.c.
395 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
397 * Added --disable-asm configuration option. Affected files
398 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
401 * Implemented the backup resuming protocol that is used to
402 resume the primary router position in the cell after the
403 primary router comes back online. Affected files
404 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
405 and silcd/server_util.[ch].
407 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
409 * Sleep two (2) seconds after sending QUIT command to server.
410 Affected file lib/silcclient/command.c.
412 * Assure that if outgoing data buffer is pending do not force
413 send any data. Affected file silcd/packet_send.c.
415 * Assure that if outgoing data buffer is pending do not force
416 send any data. Affected file lib/silcclient/client.c.
418 * Implemented the backup router support when the primary router
419 goes down. The servers and routers can now use the backup
420 router as new primary router without loosing connectivity.
422 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
424 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
425 in the server to indicate disabled entry. All data read
426 from the connection will be ignored and no data is sent
427 for entry that is disabled. Affected files are
428 silcd/idlist.h, silcd/server.c.
430 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
432 * Created SFTP client and server test programs in the
433 lib/silcsftp/tests directory.
435 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
437 * Implemented memory filesystem (virtual filesystem) for
438 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
441 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
443 * Implemented the SFTP (SSH File Transfer Protocol) to the
444 lib/silcsftp. It includes SFTP client and SFTP server
447 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
449 * Moved lib/silccore/silcprotocol.[ch] to the
450 lib/silcutil library.
452 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
453 take variable argument list pointer as argument. Affected
454 file lib/silcutil/silcbuffmt.[ch].
456 * Added silc_buffer_set function that is used to set data
457 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
458 Affected file lib/silcutil/silcbuffer.h.
460 * Changed various routines in the core library to use the new
461 silc_buffer_set instead of allocating new buffer only for
464 * Added 64-bit value formatting and unformatting support to the
465 silc_buffer_[un]format routines. Affected file is
466 lib/silcutil/silcbuffmt.[ch].
468 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
469 to includes/bitmove.h.
471 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
473 * Fixed channel user mode saving in client library. Affected
474 file lib/silcclient/command[_reply].c.
476 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
478 * Defined the file transfer to the SILC Protocol. Added
479 new packet type SILC_PACKET_FTP and defined File Transfer
480 Payload. The mandatory file transfer protocol is SFTP
481 (SSH File Transfer Protocol). Affected file in addition
482 of the internet draft is lib/silccore/silcpacket.h.
484 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
485 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
486 is used as part of backup router protocol when the primary
487 router of the cell is back online and wishes to resume
488 the position as primary router.
490 * Redefined the MAC generation keys in the protocol. The
491 same key is not used anymore in both direction. Both
492 direction will now use different keys for sending and
493 receiving. This fixes a potential security flaw. This
494 change causes incompatibilities in the protocol.
496 * Redefined also the MAC computation from the packet.
497 An packet sequence number is now added to the MAC
498 computation. This prevents possible replay attacks against
499 the protocol. This change too causes incompatibilities
502 Added `sequence' field to the SilcPacketContext to hold
503 the current sequence number for the packet.
505 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Added `created' field to the SilcIDListData in the file
508 silcd/idlist.h to indicate the time when the entry was
511 * Added `created' field to the SilcChannelEntry too. Affected
514 * Added `creation_time' aguments to all the announcement functions
515 in the server. If it is provided then only the entries that
516 was created after the provided time frame are actually
517 announced. Affected file silcd/server.[ch].
519 * The protocol says that the Channel ID's IP address must be
520 based on the router's IP address. Added check for this in
521 the silc_server_new_channel when processing incoming New Channel
522 Payload. Affected file silcd/packet_receive.c.
524 * Print out the correct version with --version in SILC client.
525 Affected file irssi/src/silc/core/silc-core.c.
527 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

530 entry always, not just when the command is coming from client.
531 Affected file silcd/command.c.
533 * Added new function silc_server_packet_queue_purge to purge the
534 outgoing data queue to the network. After the function returns
535 it is guaranteed that the outgoing packet queue is empty.
536 Affected file silcd/packet_send.[ch].
538 * Purge the outgoing packet queue in the rekey protocol's final
539 callback to assure that all rekey packets go to the network
540 before quitting the protocol. Affected file silcd/server.c.
542 * Added silc_client_packet_queue_parse as similar function as
543 in server to the client library. The affected file is
544 lib/silcclient/client.c.
546 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
548 * Splitted silcd/server.c and created silcd/server_util.[ch]
549 for utility functions.
551 * Added new socket flag SILC_SF_DISABLED to indicate that the
552 connection is open but nothing can be sent to or received from
553 the connection. Affected file lib/silcutil/silsockconn.[ch].
554 The checking for disabled socket is checked in the low level
555 silc_socket_write and silc_socket_read functions.
557 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
559 * Allow only nicknames and channel names that fits into the
560 7-bit unsigned char ASCII set. Affected file silcd/command.c.
562 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
564 * When processing JOIN command reply in server check that if
565 the channel exists in our global list we'll move it the local
566 list. Affected file silcd/command_reply.c.
568 * Fixed the check whether client is joined on the channel already
569 in JOIN command. Affected file lib/silcclient/command.c.
571 * Fixed the JOIN command reply to check whether the channel
572 already exists. Affected file lib/silcclient/command_reply.c.
574 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
576 * Added silc_ske_status_string to map the SKE error numbers
577 to readable strings. The affected files are
578 lib/silcske/silcske[_status].[ch].
580 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
582 * Do not show the private channels on the WHOIS channel list
583 as it is not allowed by the protocol. The affected file is
586 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
588 * Assure that the packet length digged from the actual packet
589 is something sensible in the silc_packet_decrypt_rest_special
590 in lib/silccrypt/silcpacket.c.
592 * Free and NULL the allocated pointer in silc_hmac_alloc if
593 the HMAC allocation fails. The affected file is
594 lib/silccrypt/silchmac.c.
596 * Print the selected security properties to the log files in
597 the server. Affected file silcd/protocol.c.
599 * Add SKE's reference counter even if calling the completion
600 callback manually. Otherwise it goes negative, although it
601 does not cause any problems. The affected file is
602 lib/silcske/silcske.c.
604 * Remove the client entry with short timeout after giving the
605 KILL command. Affected file lib/silcclient/command.c.
607 * Fixed to send error reply in WHOIS and IDENTIFY commands in
608 case all found clients are already disconnected (WHOWAS would
609 found them) in the server. Affected file silcd/command.c.
611 * Update the last_receive (time of last data received) to be
612 updated only when received private or channel message so that
613 the idle time showed in WHOIS makes more sense.
615 * Added boolean field `valid' in to the SilcClientEntry in the
616 client library to indicate whether the entry is valid or not.
617 This fixes the nickname change bug on channel when changing
618 the nickname to be same than the old (like nick to Nick) the
619 nickname formatter doesn't set the new nick anymore to Nick@host.
620 Affected file lib/silcclient/idlist.[ch].
622 * Now actually fixed the nickname changing on disconnection.
623 Added new function silc_change_nick to the Irssi SILC Client.
624 Affected file irssi/src/silc/core/client_ops.c,
625 irssi/src/silc/core/silc-nicklist.[ch].
627 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
629 * Check that the public key exists in the GETKEY command before
630 trying to encode it. Affected file silcd/command.c.
632 * Print some notifications on received public keys with GETKEY
633 command in the Irssi SILC Client. Affected files are
634 irssi/src/fe-common/silc/module-formats.[ch],
635 irssi/src/silc/core/client_ops.c.
637 * Use IDENTIFY command to resolve the server information in the
638 GETKEY command instead of INFO command. Affected file
639 lib/silcclient/command.c.
641 * All command reply functions in the client library now calls
642 the pending command reply callbacks even if an error has
643 occurred. The server has done this a long time and now it was
644 time to move the client library to this as well. Now all
645 errors can be delivered back to the pending command reply
646 callbacks if necessary. Affected files are
647 lib/silcclient/command[_reply].[ch].
649 * Change the nickname on disconnection back to the username
650 because in reconnect the server will enforce it to it anyway.
651 Affected file irssi/src/silc/core/silc-servers.c.
653 * Fixed a config file parsing bug in the Irssi SILC client.
654 Affected file irssi/src/silc/core/clientconfig.c.
656 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
658 * When printing the channel mode on JOIN, verify that the
659 channel key and channel's HMAC are valid. Affected file
660 irssi/src/silc/core/client_ops.c.
662 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
664 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
665 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
666 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
668 * Removed channel key rekey task deleting from the function
669 silc_server_save_channel_key. Affected file silcd/server.c.
670 Added explicit timeout task context instead that is used to
671 delete the task if we are registering a new task before the
672 new task has elapsed.
674 * When channel key rekey occurs the client library now saves
675 the old channel key for a short period of time (10 seconds) and
676 is able to use it in case some is still sending channel
677 messages encrypted with the old key after the rekey. Affected
678 file lib/silcclient/[idlist.h|client_channel.c].
680 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
682 * Added check to the silc_server_new_id_real to not accept
683 new ID if it is the sender's own ID. Affected file is
684 silcd/packet_receive.c.
686 * Assure that we do not announce ourself or the one we've
687 sending our announcements when we're router and are announcing
688 servers to our primary router. Affected file silcd/server.c.
690 * Fixed silc_server_command_identify_check_client to assemble
691 correct WHOIS packet. It send corrupted WHOIS packet and
692 caused problem with router to router connections. Affected
693 file silcd/command.c.
695 Fixed also silc_server_command_whois_check the same way
696 as for the IDENTIFY command.
698 * Added new SilcIDListStatus to the server in the SilcIDListData
699 structure. The status now includes the current status of
700 the entry (like registered, resolved etc.). Affected file
701 silcd/idlist.[ch]. Defined a bunch of different status types
702 as well. This replaced the old boolean registered field as well.
704 Added resolve_cmd_ident field to the SilcClientEntry structure
705 too so that if the entry is for example being resolved so
706 another command may attach to the same pending command reply
707 without requiring to resolve the same entry again. This concept
708 should optimize the WHOIS and the IDENTIFY resolving under
709 heavy load by taking away unnecessary resolving for entries
710 that are being resolved already.
712 Added support for adding multiple pending commands for one
713 command idenfier. Affected file silcd/command[_reply].[ch].
715 * Fixed WHOIS and IDENTIFY save to remove the cache entry
716 before deleting the data. Otherwise the hash table will have
717 freed data in comparison functions. Affected file is
718 silcd/command_reply.c.
720 * Fixed silc_idlist_replace_client_id to add the new entry to
721 the cache with NULL nickname. Otherwise there will be invalid
722 memory as the nickname after the nickname is freed. Affected
723 file silcd/packet_receive.c.
725 * Fixed the silc_idlist_get_clients_by_hash. The entries was
726 saved into wrong slots because the previous number of entries
727 was not taken into account. Affected file silcd/idlist.c.
728 Fixed same thing in silc_idlist_get_clients_by_nickname too.
730 * If we are router and we receive JOIN notify to a channel that
731 does not have any users then notified client is marked as the
732 channel founder, as it is it. The affected file is
733 silcd/packet_receive.c
735 * Added to the extended hash table API's table_del_*ext functions
736 the destructor as argument too, so that the caller can decide
737 which destructor to use or whether to use destructor at all.
738 Affected file lib/silcutil/silchashtable.[ch].
740 * Fixed ID Cache purging. It actually deleted the entries from
741 the hash table after the data was freed. The hash table ended
742 up comparing freed memory. The affected file is
743 lib/silccore/silcidcache.c.
745 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
747 * Fixed Irssi SILC client's KILL command's HELP syntax.
749 * The USERS command now resolves the detailed user information
750 if the userinfo field is missing. Affected file is
751 lib/silcclient/command_reply.c.
753 * Do not print error in silc_file_read if the read file does
754 not exist. Just silently return NULL. Affected file is
755 lib/silcutil/silcutil.c.
757 * Fixed the silc_log_output to not wine about NULL filename
758 and to not create some bogus " " filename. Affected file is
759 lib/silcutil/silclog.c.
761 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
763 * Fixed various printing bugs on the user interface in the
764 Irssi SILC Client. Minor changes that were forgotten from
767 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
769 * Fixed the configure.in.pre and the compilation and distribution
770 environment to support the new autoconf 2.52. That version is
771 now required to compile the CVS trunk.
773 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
775 * Renamed function silc_parse_nickname to silc_parse_userfqdn
776 to generally parse user@fqdn format strings. Affected file
777 lib/silcutil/silcutil.c.
779 * Added nickname_format and nickname_force_format fields to the
780 SilcClientParams structure. The first one defines the format
781 for the nicknames that the library will enforce if the receives
782 multiple same nicknames. The second one is boolean value and
783 can be used to force the library to always enforce the format
784 to the nicknames regardles whether there are multiple nicknames
785 or not. This configurable formatting was employed to flexibly
786 support accessing multiple nicknames from the user interface.
787 The userinterface can now set the nicknames to what ever format
788 they prefer. Affected file lib/silcclient/silcapi.h.
790 Added function silc_client_nickname_format to the file
791 lib/silcclient/idlist.c. It performs the nickname formatting.
793 Added new field `hostname´ to the SilcClientEntry context.
794 It holds the hostname of the client. Affected file is
795 lib/silcclient/idlist.h.
797 * Irssi SILC Client sets the nicknames in nick@hostn format.
798 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
799 irssi/src/silc/core/silc-core.c.
801 The WHOIS printing now also shows both the real nickname and
802 the formatted nickname so that user knows how to access the
803 user if there are multiple same nicknames cached. Affected
804 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
805 printing formatting too to take the hostname now as a separate
806 argument. The Affected file is
807 irssi/src/fe-common/silc/modules-formats.[ch].
809 * Changed the silc_client_get_clients_local to accept the formatted
810 nickname as argument. It accepts the real nickname too but the
811 formatted nickname can be used to find the true entry from
812 multiple entries. Affected file lib/silcclient/silcapi.h and
813 lib/silcclient/idlist.c.
815 * Added nickname_format_parse field to the SilcClientParams.
816 It is a callback function provided by the application to parse
817 the nickname out of the formatted nickname string. The library
818 calls it to get the nickname from the formatted string. Since
819 the application generally knows better the format of the nickname
820 string it parses it instead of the library, even though library
821 encodes the formatted string. If the callback function is not
822 provided then the library will use the string as is. The
823 affected file is lib/silcclient/silcapi.h.
825 * All the nickname strings passed to the client library in
826 commands are now expected to be formatted nickname strings.
827 If the command does not support the formatted nickname string
828 it will assume that the sent string is the actual nickname.
829 Affected file lib/silcclient/command.c.
831 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
833 * Added public key authentication support to OPER and SILCOPER
834 commands in the client library. Affected file is
835 lib/silcclient/command.c.
837 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
839 * Changed the get_auth_methdod client operation to be asynchronous.
840 It can be async if the application resolves the authentication
841 method from the server during the negotiation. Added new
842 SilcGetAuthMeth completion callback that the application will
843 call after resolving the authentication method.
845 Added function silc_client_request_authentication_method that
846 the application can use to resolve the authentication method
847 from the server. Added also SilcConnectionAuthRequest callback
848 that the library will call after the server has replied. The
849 application can call this function if it does not know the
850 current authentication method.
852 Affected files are lib/silcclient/client.c and
853 lib/silcclient/silcapi.h.
855 * The Irssi SILC client now automatically resolves the authentication
856 method incase any configuration information is not present (and
857 currently there never is). The affected file is
858 irssi/src/silc/core/client_ops.c.
860 * Fixed public key authentication from the client library.
861 Affected file lib/silcclient/protocol.c. Changed also the
862 protocol specification about the public key authentication in
863 the connection authentication protocol. The actual data to be
864 signed is now computed with a hash function before signing.
866 * Fixed the public key authentication from the server as well.
867 Affected file silcd/protocol.c.
869 * Removed the mlock()'s from the memory allocation routines.
870 Affected file lib/silcutil/silcmemory.c. The ./configure does
871 not check anymore for the mlock(). Affected file is
874 * Fixed USERS command in server to allow the execution of the
875 command for private and secret channels if the client sending
876 the command is on the channel. Affected file silcd/command.c.
878 * Fixed silc_client_get_clients_local to return the clients
879 count correctly. It could return wrong value. Affected file
880 lib/silcclient/idlist.c.
882 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
884 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
885 types. The assembler optimizations seemed not to like 64-bit
886 data types. The assmebler optimizations thus are now enabled
887 also for BSD systems as opposed to only enable them for Linux.
889 * Do not check for threads at all on BSD systems. Affected
890 file configure.in.pre.
892 * Removed -n and -h options from the Irssi SILC Client since
893 they are not used in silc.
895 * Fixed the prime generation to assure that the first digit
896 of the generated random number is not zero since our conversion
897 routines does not like number strings that starts with zero
898 digit. If zero digit is seen the random number is regenerated.
899 This caused some corrupted RSA keys when the zero first digit
900 was met. Affected file lib/silcmath/silcprimegen.c.
902 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
904 * Fixed WIN32 configuration in the ./configure script.
905 Fixed to include xti.h on environments that has it.
906 Patches by Carsten Ilchmann and andrew.
908 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
910 * Changed the silc_id_create_client_id to be collision
911 resistant. It is now assured that there cannot be created
912 two same client ID's. I suspect that some weird bugs in
913 the server were actually caused by duplicate Client IDs.
914 Affected file silcd/serverid.[ch]. A router receiving
915 new ID now also assures and informs the sending server
916 if the ID caused collision.
918 * Changed the silc_id_create_channel_id to also assure that
919 there are no collisions.
921 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
923 * Statement about ignoring the Mutual Authentication flag when
924 performing rekey with PFS was a bit misleading. It is ignored
925 if it was set in the initial negotiation, it cannot be even
926 set in the rekey. Fixed in the ke-auth draft. Started the
927 new versions of the protocol drafts in the doc/.
929 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
931 * Fixed a bug in silc_client_command_identify_save when saving
932 new channel information. The channel name was no duplicated
933 and caused crash on exit. Affected file is
934 lib/silcclient/command_reply.c.
936 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
938 * Fixed the getkey command handling in the server. Send just
939 empty OK reply to the sender if the key could not be fetched
940 (but everything else was ok, like the key just was not available).
941 Changed the public key parameter to optional in the protocol
942 specs so that empty OK reply can be sent. Affected file
945 Added a message to Irssi SILC client to tell to user if the
946 server did not return a public key.
948 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Fixed a channel key regeneration bug. It registered new
951 timeout tasks exponentially until all system resources were
952 used. Affected file silcd/server.c.
954 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
956 * Added the SILC Document generator to the scripts/silcdoc.
957 It can be used to generate the Toolkit Reference Manual out
958 of the source tree. Internally it will also use the RoboDoc
959 generator now imported in util/robodoc.
961 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
963 * Added couple of return's in rekey protocol if error orccurred
964 during the protocol. The execution must be terminated.
965 Affected file silcd/protocol.c. Also, terminate the protocol
968 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
970 * The client's Client ID was created initally from the wrong
971 nickname (it could have been in format nick@host) in the
972 silc_server_new_client. Affected file silcd/packet_receive.c
974 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
976 * Added some SILC_LOG_ERROR's to various error conditions
977 if client could not be added to ID cache. Affected files
978 silcd/packet_receive.c and silcd/server.c.
980 * When client's sock->user_data is freed, NULL also the
981 client->router and client->connection pointers. Added check
982 for these pointers being NULL to various places around the
983 code. Affected file silcd/server.c.
985 * Added client->data.registered == TRUE checks to various
986 places around the code to assure that unregistered client's
987 are not handled when it is not allowed. Affected file
990 * Added `bool registered' fields to all
991 silc_idlist_[server|client]_get_* routines to indicate whether
992 the fetched client needs to be registered or not. Affected
993 file silcd/idlist.[ch].
995 * Add your own entry as registered to the ID cache in the
996 server. Affected file server.c.
998 * Fixed a bug in silc_server_new_server. The SilcServer was
999 set as the new server's context instead of SilcServerEntry.
1000 This naturally caused some weird bugs.
1002 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1004 * Do not delete the channel rekey task when adding it
1005 for in silc_server_create_channel_key.
1007 * Changed the silc_server_create_channel_key to return
1008 TRUE or FALSE to indicate the success of the channel key
1011 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1013 * Fixed MSVC++ project files and added missing files to
1014 Makefiles under win32/.
1016 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1018 * Do not add TCP_NODELAY flag if the operating system
1019 does not have it defined. Affected files are
1020 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1022 * Fixed buffer overflow from Irssi SILC Client. Affected
1023 file irssi/src/fe-common/core/themes.c.
1025 * Fixed double free in client library in the file
1026 lib/silcclient/client.c when disconnecting from server.
1028 * Applied double free patch from cras to Irssi SILC client.
1029 Affected files irssi/src/core/[modules/expandos].c
1031 * Fixed the disconnection handling to Irssi SILC Client.
1032 The application must call silc_client_close_connection
1033 in ops->connect client operation in case of failure of
1034 the connection. Affected file is
1035 irssi/src/silc/core/client_ops.c.
1037 * Do not set sock->protocol to NULL in the function
1038 silc_client_close_connection after executing the protocol's
1039 final callback since the sock might not be valid anymore.
1040 Affected file lib/silcclient/client.c.
1042 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1044 * Do not enable SILC_THREADS if the linking with libpthread
1045 did not happen. Affected file configure.in.pre.
1047 * Added notion to protocol specification that server must
1048 verify the sent authentication payload with CMODE when
1049 setting the channel founder key. Implemented it to the
1050 server. Affected file silcd/command.c.
1052 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Added _EXTRA_DIST SILC distribution variable to the
1055 distributions file. It is used to conditionally add extra
1056 files or directories to the specific distribution. Affected
1057 files ./prepare, Makefile.am.pre and distributions.
1059 Removed the `_' from the start of the distribution names.
1062 * Added README.WIN32 for instructions to compile the Toolkit
1065 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1067 * Fixed a double free in disconnection in the server. Affected
1068 file is silcd/server.c.
1070 * Fixed the lib/silcske/groups.c to work now also with GMP
1071 MP library. The string conversion did not work when using
1072 specific base and the base is indicated in the string as well.
1074 * Created win32/ directory which now includes MSVC++ specific
1075 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1076 It will appear only in the toolkit distribution
1078 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1080 * Changed the key material distribution function in case when
1081 the hash output is too short. The data is now concatenated
1082 a bit differently than it used to. Made the change to the
1083 SKE protocol specification.
1085 * Added better GMP detection to configure.in.pre. A patch
1088 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1090 * Fixed a minor bug in SKE that might cause some problem on
1091 some platforms. Affected file lib/silcske/silcske.c.
1093 * Added the cookie checking for initiator in the SKE. It checks
1094 that the responder returns the sent cookie unmodified. The
1095 affected file is lib/silcske/silcske.c. Added new SKE
1096 error type INVALID_COOKIE that can be sent during the
1097 negotiation. Fixed some memory leaks as well.
1099 * Added the "invalid cookie" error message to Irssi SILC client's
1102 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1104 * Added `task_max' field to the SilcClientParams to indicate
1105 the maximum tasks the scheduler can handle. If set to zero,
1106 default values are used. Affected file lib/silcclient/silcapi.h.
1108 * Fixed memory leaks in silc_client_close_connection. Affected
1109 file lib/silcclient/client.c.
1111 * Added silc_client_del_client_entry to client library to free
1112 all memory of given client entry. Affected file is
1113 lib/silcclient/idlist.[ch].
1115 * Added new functions silc_client_del_channel and
1116 silc_client_del_server to delete channel and server entries.
1117 Affected file lib/silcclient/[silcapi.h/idlist.c].
1119 * Removed silc_client_del_client_by_id from silcapi.h.
1121 * Fixed the INFO command to return the server's own info
1122 correctly when querying by Server ID. Affected file is
1125 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * Removed the non-blocking settings in WIN32 code in the
1128 silc_sock_[read/write] and added SleepEx instead. Affected
1129 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1130 of input data is now checked with FIONREAD and ioctlsocket.
1132 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1134 * Call silc_schedule_task_del_by_context in the
1135 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1136 Affected file lib/silccore/silcprotocol.c.
1138 * Call silc_protocol_cancel for active protocols in the
1139 silc_server_close_connection if the funtion
1140 silc_server_free_sock_user_data has not been called.
1141 Affected file silcd/server.c.
1143 * Generic tasks cannot be deleted using the del_by_fd
1144 task deleting function since generic tasks does not match
1145 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1147 * Added a notion to SILCOPER help file that the SILCOPER works
1148 only on router server, not on normal server.
1150 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1152 * Added for WIN32 support for the new scheduler as well.
1153 Affected file lib/silcutil/win32/silcwin32schedule.c.
1155 * Fixed the SHA1 implementation to work on various platforms.
1157 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1159 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1160 API. It is part of the scheduler now. Everything else is
1161 as previously but some functions has changed their names.
1162 Checkout the lib/silcutil/silcschedule.h for the interface.
1163 Updated all applications to use the new interface. Affected
1164 files are lib/silcutil/silcschedule.[ch].
1166 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Found a bug in the SKE implementation. The HASH value,
1169 specified by the protocol, was not computed correctly. The
1170 public key of the responder was not added to the computation
1171 even though it is mandatory. Affected file lib/silcske/silcske.c.
1172 This unfortunately causes incompatibilities with older
1173 clients and servers.
1175 * Added WIN32 specific network init and uninit functions:
1176 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1177 the Winsock2. Affected file lib/silcutil/silcnet.h and
1178 lib/silcutil/win32/silcwin32net.c.
1180 * Set the socket always to nonblocking mode on WIN32 after
1181 reading data or writing data. Affected file is
1182 lib/silcutil/win32/silcwin32sockconn.c.
1184 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1186 * Fixed various compilation problems under WIN32. Affected
1187 files lib/silcutil/win32/silcwin32thread.c and
1188 lib/silcutil/win32/silcwin32schedule.c.
1190 * Removed all _internal.h #includes from public header
1191 files. Internal headers must never be included from
1194 Removed also the lib/silcske/payload_internal.h file.
1196 * All include files that may be needed (public and some others
1197 included by the public headers) by application developers are
1198 now copied to the ./includes directory. It does not copy any
1199 internal headers. Affected file Makefile.defines.pre and all
1200 Makefile.am's under lib/ and subdirs.
1202 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1204 * Do not change the ~/.silc directory's permissions automatically.
1205 Affected file irssi/src/silc/core/clientutil.c.
1207 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1209 * Do not cancel the protocol in silc_server_close_connection
1210 it might cause recursion. Now cancelled in the function
1211 silc_server_free_sock_user_data. Affected file silcd/server.c.
1213 * Fixed the silc_server_remove_clients_by_server to regenerate
1214 the channel keys correctly finally. Added also new function
1215 silc_server_remove_clients_channels to actually do it.
1216 Affected file silcd/server.c.
1218 * Fixed the silc_server_new_channel to not crash by giving
1219 wrong router to the new channel. Affected file is
1220 silcd/packet_receive.c.
1222 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1224 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1225 which is given as argument to the silc_client_alloc now.
1226 It can be used to configure the client and set various parameters
1227 that affect the function of the client.
1229 * The USERS command in server did not check whether the channel
1230 is private or secret. Affected file silcd/command.c.
1232 * Added new argument to the USERS command in protocol specification.
1233 The USERS command now can take the channel name as argument
1234 as well. Added support for this in client and server and
1235 updated the protocol specs.
1237 * Completed the GETKEY command in client. It can be now used
1238 to fetch also servers public key not only some clients.
1239 Affected files lib/silcclient/command[_reply].c.
1241 * Added silc_client_get_server to return server entry by the
1242 server name. Affected files lib/silcclient/silcapi.h and
1245 * Redefined the IDENTIFY command in protocol specification to be
1246 more generic. It now can be used to query information about
1247 any entity in the SILC Network, including clients, servers and
1248 channels. The query may be based either the entity's name
1249 or the ID. Added support for this in both client and server.
1251 Affected files silcd/command.c and lib/silcclient/command.c
1252 and command_reply.c.
1254 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1255 the _from_client and _from_server functions. Affected file
1258 * Added silc_client_get_channel_by_id_resolve to the file
1259 lib/silcclient/silcapi.h to resolve channel information by
1260 its ID. Added also silc_client_get_channel_by_id that
1261 does not resolve it from the server.
1263 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1265 * Added SilcServerEntry context into the client library
1266 to represent one server. The INFO command now allocates
1267 these to save the resolved server info. For now on the
1268 client library will also keep information about servers,
1269 connected and resolved with INFO.
1271 The INFO command now allocates the SilcServerEntry context
1272 and saves the server info there. The COMMAND_REPLY in
1273 the INFO now returns the parameters to application in
1274 same order as defined in the protocol specification.
1276 The entries are cached in the client->server_cache.
1278 * The INFO command is now issued after received the Client ID
1279 from the server. Affected file lib/silcclient/client.c.
1281 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1282 to the application as the mode changer might be server.
1283 It is guaranteed that NULL is not returned anymore to the
1284 application. Affected file lib/silcclient/client_notify.c.
1286 The ID Type is now also passed to the application so that
1287 it can check whether the returned entry is SilcClientEntry
1290 Added new function silc_client_get_server_by_id to return
1291 the server entry by ID. Affected files are the
1292 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1294 * Do not create the channel in the Irssi SILC Client when issuing
1295 the JOIN command but when received the sucessful JOIN command
1296 reply. Otherwise the channel might get created even though we
1297 could not join it. The Affected file is
1298 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1300 * Fixed a channel joining bug in router. The router must also
1301 check the channel modes, invite and ban lists etc. when serving
1302 the JOIN command sent by normal server. Affected file is
1303 silcd/command.c. The router now resolves the client's
1304 information from the server who sent the JOIN command if it
1305 does not know it, and processes the JOIN command only after
1308 * Changed the SilcCommandCb to take new argument; void *context2.
1309 Affected file lib/silccore/silccommand.h
1311 The second argument in the command callbacks in the server now
1312 includes the SilcServerCommandReplyContext if the command was
1313 called as pending command callback from the command reply.
1314 Otherwise it is NULL. When called as pending the status of the
1315 command reply will be checked and if it was erronous the
1316 error will be sent to the original sender of the command.
1317 This way the client always receives the error messages even
1318 though the server was actually the one who received the error
1319 when it resent the command to router, for example. Affected
1320 files silcd/command[_reply].[ch].
1322 * Fixed sending WHOWAS command's error message to client if
1323 the requested client could not be found. It was missing.
1326 * Changed the CMODE and CUMODE commands reply arguments in the
1327 protocol specification. The Channel ID is now sent in both
1328 of the commands to identify the channel. Implemented this
1329 new feature to the client and server. Affected files
1330 lib/silcclient/command_reply.c and silcd/command.c.
1332 * Made better checks for invite and ban lists in the JOIN
1333 command in server. Affected file silcd/command.c.
1335 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * The server now performs the incoming host IP/DNS lookup
1338 using the silc_socket_host_lookup and thus does not block
1339 the server anymore. Affected file silcd/server.c.
1341 * Completed the multi-thread support for SILC Scheduler in
1342 the lib/silcutil/silcschedule.c.
1344 * Fixed the configure.in.pre to detect the pthread correctly
1347 * Fixed a deadlock in silc_task_queue_wakeup in the file
1348 lib/silcutil/silctask.c.
1350 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1352 * Added new function silc_schedule_wakeup that is used in
1353 multi-threaded environment to wakeup the main thread's
1354 schduler. It needs to be used when a thread adds a new task
1355 or removes a task from task queues. After waking up, the
1356 scheduler will detect the task queue changes. If threads
1357 support is not compiled in this function has no effect.
1358 Implemented the wakeup mechanism to both Unix and WIN32
1359 systems. Affected files are lib/silcutil/silcschedule.[ch],
1360 lib/silcutil/unix/silcunixschedule.c and the
1361 lib/silcutil/win32/silcwin32schedule.c.
1363 * Added new function silc_task_queue_wakeup to wakeup the
1364 scheduler by the specified task queue. Affected file
1365 lib/silcutil/silctask.[ch].
1367 * The silc_socket_host_lookup_start now wakes up the scheduler
1368 after adding the timeout task. Affected file is
1369 lib/silcutil/silcsockconn.c.
1371 * The silc_socket_host_lookup is synchronous now if the threads
1372 support is not compiled in. However, the callback is still
1373 called asyncronously through the scheduler, anyway. Affected
1374 file lib/silcutil/silcsockconn.c.
1376 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Added new function silc_socket_host_lookup to perform
1379 asynchronous IP and FQDN lookups for the socket connection.
1380 Affected files lib/silcutil/silcsockconn.[ch].
1382 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1385 that may or may not compile the mutex support in.
1387 Changed the silc_mutex_alloc interface. It allocates the
1388 mutex now to the sent pointer and returns TRUE or FALSE.
1390 Affected file lib/silcutil/silcmutex.h.
1392 * Wrote the SILC Task Queue interface to support multi-threads.
1393 Affected file lib/silcutil/silctask.[ch].
1395 * Wrote the SILC Scheduler to support multi-threads. Affected
1396 file lib/silcutil/silcschedule.c.
1398 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1400 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1401 in lib/silcutil/win32/.
1403 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1405 * Defined SILC Mutex API and SILC Thread API and implemented
1406 them for Unix. Affected files are
1407 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1408 lib/silcutil/unix/silcunixmutex.c and
1409 lib/silcutil/unix/silcunixthread.c.
1411 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1413 * Fixed the silc_server_remove_clients_by_server's channel
1414 key re-generation. The hash table handling was incorrect
1415 and would not work with many channels. Affected file is
1418 * Fixed some memory leaks around the server code.
1420 * Rewrote the silc_server_get_users_on_channel to support IPv6
1421 based Client ID's. Affected file silcd/server.c.
1423 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1424 specification. However, a separate document must be written
1425 to define the detailed signing procedure and the payload
1426 associated with the flag. Defined the flag to the
1427 lib/silccore/silcchannel.h as well.
1429 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * Changed the dynamic tables to static size tables in the
1432 lib/silccrypt/silchmac.c.
1434 * Removed GCC dependencies from the code. A patch by cras.
1436 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Do not show the error "Error receiving packet bla bla"
1439 in server if it really was not an error (-2 means that reading
1440 is pending). Affected file silcd/server.c.
1442 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1444 * Fixed a possible crash in silc_server_remove_clients_by_server
1445 in silcd/server.c. Fixed there also some memory leaks.
1447 * Fixed the silc_idlist_replace_client_id. It could replace
1448 wrong key in the hash table. Affected file silcd/idlist.c.
1450 * Do not check whether there are global users on the channel
1451 if the channel->global_users is FALSE. Affected functions
1452 silc_server_remove_from_one_channel and
1453 silc_server_remove_from_channels in silcd/server.c. Also,
1454 do not check if the removed client is local as we can be
1455 sure that global client was not removed from the channel
1456 and checking for global users is not needed.
1458 * The silc_server_remove_clients_by_server now re-generates
1459 the channel keys correctly for those channels that had
1460 clients removed from them. Affected file silcd/server.c.
1462 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1464 * Found the reason of random crashes in the server. We weren't
1465 ignoring the SIGPIPE signal (which can be sent in write())
1466 and it crashed the server. Affected file silcd/silcd.c.
1468 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Assure that sock->user_data is not NULL in the function
1471 silc_server_packet_send in silcd/packet_send.c.
1473 * Disconnect the remote connection if it could not be added
1474 to any ID lists in the server. The affected file is
1477 * Check in silc_server_packet_send[_real/dest] that the
1478 socket is not disconnecting and ignore the data if it is.
1479 Affected file silcd/packet_send.c.
1481 * Define inline to __inline on native WIN32 compilation.
1482 Affected file includes/silcwin32.h.
1484 * Added some explicit type casts for inline code since MSVC
1485 require them. Affected files lib/silcutil/silcbuffer.h,
1486 lib/trq/silcdlist.h and lib/trq/silclist.h.
1488 * Print warning in log files from now on if the packet
1489 decryption fails. Affected file silcd/server.c.
1491 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1493 * Changed the `say' client operation's interface to accept
1494 new `type' argument to indicate the type of the message sent
1495 by the library. The application may filter the library's
1496 messages according the type. The affected file is the
1497 lib/silcclient/silcapi.h.
1499 * Added two new functions to lib/silcclient/silcapi.h:
1500 silc_client_del_client and silc_client_del_client_by_id.
1501 Affected file lib/silcclient/idlist.c.
1503 * Moved the clientincludes.h from includes/ to silc/ and
1504 serverincludes.h from includes/ to silcd/.
1506 * The modes for the CMODE and CUMODE are now passed as
1507 uint32 for application with COMMAND_REPLY. The affected
1508 file is lib/silcclient/command_reply.c.
1510 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1512 * /WHOIS without arguments shows client's own information.
1513 Affected file lib/silcclient/command.c.
1515 * Changed PING to not accept any arguments. The specs
1516 says that client can ping only the connected server so
1517 requiring an argument is not needed. Affected file is
1518 lib/silcclient/command.c.
1520 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1522 * Fixed a fatal bug in private message sending and reception
1523 encryption and decryption when using private message keys.
1524 The implementation was incorrect and did not follow the
1525 specification. It causd that some of the message were
1526 lost since it did not use the sending and receiving keys
1527 as the protocol suggests. This has been fixed and will cause
1528 incompatibilities with older clients when sending private
1529 message encrypted with private message keys. Affected files
1530 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1531 and various other in Irssi SILC Client.
1533 Added `responder' boolean argument to the functions
1534 silc_client_add_private_message_key[_ske] to indicate when
1535 the key is added as responder or initiator of the key
1538 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1540 * Removed the silc_ske_check_version function and created
1541 a SilcSKECheckVersion callback. Added also a function
1542 silc_ske_set_callbacks that is now used to set all SKE
1543 callbacks. The callback functions are not given to
1544 the SKE functions anymore, but this function is used to
1547 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1549 * Added `silc_version' argument to the silc_client_alloc
1550 to define the version of the application for the library.
1551 The library will use the version string to compare it
1552 against the remote host's (usually a server) version
1553 string. Affected file lib/silcclient/silcapi.h
1555 * Added the KE protocol context to Key Agreement context
1556 in client library so that we can abort the SKE if it
1557 is in process when we get timeout. Affected file is
1558 lib/silcclient/client_keyagr.c.
1560 * Do not resolve the client ID forever if it returns in the
1561 first time that such client does not exist. This was done
1562 for example with private message. Affected file is
1563 lib/silcclient/client_prvmsg.c.
1565 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1567 * Do not add regex.h for WIN32. The affected file
1568 includes/silcincludes.h.
1570 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1571 not work yet 100%. It generates the DLL's automatically
1572 when compiling with --with-win32 under cygwin.
1574 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1576 * lib/contrib/regex.c is not compiled on WIN32.
1578 * Added silc_net_get_socket_opt function to the
1579 lib/silcutil/silcnet.h.
1581 * Added includes/silcwin32.h for WIN32 specific includes
1584 * Do not use ptime structure or any of the posix process
1585 functions on WIN32 in lib/silccrypt/silrng.c.
1587 * Added silc_gettimeofday to provide generic function
1588 for struct timeval on all platforms. Added the function
1589 to lib/silcutil/silcutil.h.
1591 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1593 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1594 library as they clearly belong there. As a plus side we
1595 can make the actual socket connection routines platform
1598 Added also new generic function silc_socket_read and
1599 silc_socket_write (that used to be silc_packet_[read/write].
1600 The implementation of these are platform specific.
1602 * Added WIN32 specific routines of silc_socket_[read/write]
1603 to lib/silcutil/win32/silcwin32sockconn.c.
1605 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1607 * Added preliminary support for native WIN32 compilation under
1608 cygwin (using the -mno-cygwin option for GCC) to the
1609 ./configure.in.pre. The --with-win32 now prepares the
1610 compilation for native WIN32.
1612 * Rewrote the SILC Scheduler interface in the file
1613 lib/silcutil/silcschedule.h. The scheduler is now context
1614 based and does not have anymore any global static scheduler.
1615 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1616 and created lib/silcutil/win32 directory for WIN32 based
1619 * Added Unix specific network routines to the
1620 lib/silcutil/unix/silcunixnet.c and the old
1621 lib/silcutil/silcnet.c includes now only generic routines.
1623 Added WIN32 specific network routines to the
1624 lib/silcutil/win32/silcwin32net.c.
1626 * Added Unix specific utility functions from the
1627 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1629 * Added WIN32 SILC Scheduler to the file
1630 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1633 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Do not handle JOIN notify in the server if the target client
1636 is not registered (idata->registered == FALSE). The affected
1637 file is silcd/packet_receive.c.
1639 * Update the nickrec->founder in event_cumode in the Irssi SILC
1640 client. Affected file irssi/src/silc/core/silc-channels.c.
1642 * Fixed the CUMODE_CHANGE notify handling in the server when
1643 server and router are announcing their clients on channels.
1644 Now the mode changes are saved and notified correctly. The
1645 affected file is /silcd/packet_receive.c.
1647 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1648 They really did not replace the cache entry in the ID Cache.
1649 Now they do that. Affected file silcd/idlist.c.
1651 * Fixed the KICK notify handling in the Irssi SILC client to
1652 update the channel records so that the kicked client does not
1653 appear to be on the channel. The affected file is
1654 irssi/src/silc/core/silc-channels.c.
1656 * Always update the conn->current_channel when executing command
1657 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1659 * Fixed the KILL notify handling in Irssi SILC client to remove
1660 the killed client on all channels.
1662 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Fixed the silc_parse_command_line to remove extra spaces
1665 from the start and end of the arguments. Affected file is
1666 lib/silcutil/silcutil.c.
1668 * Cancel and free any active protocol in the function
1669 silc_server_close_connection. Affected file silcd/server.c.
1671 * Cancel and free any active protocol in the function
1672 silc_client_close_connction. Affected file is
1673 lib/silcclient/client.c.
1675 * Do not execute the KILL command for clients that are in
1676 history (ie. they are not in the network). Affected file is
1679 * Fixed KILL notify handling, client does not crash anymore.
1680 Affected file irssi/src/silc/core/silc-channels.c.
1682 * Reduced the default packet buffer size from 2048 to 1024 in
1683 lib/silccore/silcpacket.c.
1685 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1686 counter to the SKE context that is incresed when the SKE library
1687 performs async operation outside the library. If the outside
1688 process frees the SKE context and FREED status will be set
1689 and the library will detect after the sync operation that the
1690 libary is freed. The affected files are
1691 lib/silcske/silcske[_status].[ch].
1693 * Resolve the client entry information in the function
1694 silc_client_channel_message to assure that NULL pointer is not
1695 passed as client entry to the application. */
1697 * Fixed the task timeout calculation to assure that there is
1698 never negative timeouts. The affected file is
1699 lib/silcutil/silcschedule.c.
1701 * Fixed the channel user mode notification sending in server.
1702 It was sent point-to-point to the router (or to server by router)
1703 but it needs to be destined to a channel. The routines now
1704 supports sending the channel user mode notifys to the channels
1705 when announcing clients and channels. Affected files are
1706 silcd/server.c and silcd/packet_receive.c.
1708 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1709 It did not actually replace the old channel entry in the cache.
1710 Affected file lib/silcclient/client_notify.c.
1712 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1714 * Fixed a possible crash in silc_packet_send_prepare. It now
1715 assures always that there is enough space in the buffer and
1716 at the tail area of the buffer (for MAC).
1718 Fixed the inbound buffer reallocation in silc_packet_read.
1719 It was old code and did not handle the reallocation correctly.
1722 The affected file is lib/silccore/silcpacket.c.
1724 * Fixed buffer overflow in silc_parse_nickname in the file
1725 lib/silcutil/silcutil.c.
1727 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * make install generates new server keys only if there is not
1732 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1735 Added check that if the NOREPLY is set then we will not send
1736 the away message. This avoids infinite loop of away messages
1737 if both clients are away. The affected file is
1738 lib/silcclient/client_prvmsg.c.
1740 * Fixed client crash if /NICK was given without arguments.
1741 Affected file lib/silcclient/command.c.
1743 * Server does not send the invite list in INVITE command back
1744 to the client if the list was not altered. Added this notion
1745 to the protocol spec as well. Affected file silcd/command.c.
1747 Fixed possible crash in INVITE command by checking the
1748 value of silc_server_get_client_route command.
1750 * Fixed the INVITE notify type handling. The arguments are now
1751 taken in correct order and client does not crash. The affected
1752 file is irssi/src/silc/core/silc-channels.c.
1754 Removed the "Inviting xxx to channel" message from the
1755 client library away and let the application handle it.
1756 Affected file lib/silcclient/command.c. Added that message
1757 to Irssi SILC client's message formats.
1759 * Fixed CMODE command crash in client. It now checks the
1760 amount of arguments correctly and does not crash. The affected
1761 file is lib/silcclient/command.c.
1763 * Do not create new channel automatically in silc_channels_join
1764 but check whether the channel by that name already exists.
1765 Affected file irssi/silc/core/silc-channels.c.
1767 * Do not send the SERVER_SIGNOFF to router if the disconnected
1768 entity was the router. Affected file silcd/server.c.
1770 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1771 SILC client as it was missing from there.
1773 Added the handling of the KICK notify to the Irssi SILC client
1774 as it was missing. Added "you have been kicked" message to
1775 Irssi SILC client's message modules formats.
1777 Added the handing of the KILL notify to the Irssi SILC client
1778 as it was missing. Added the kill message module formats
1781 The affected file is irssi/src/silc/core/silc-channels.c.
1783 * The router did not save the channel mode the server announced.
1784 Affected file silcd/packet_receive.c.
1786 * Fixed a possible crash in INFO command in server. If the
1787 server did not provide the server info it crashed. Affected
1788 file silcd/command.c.
1790 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Fixed the GETKEY command in the server to check also the
1793 global list. Otherwise the GETKEY would not work correctly
1794 in normal SILC server. Affected file silcd/command.c.
1796 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Fixed GETKEY crash, it crashed if the command did not succseed.
1800 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1803 is now real and not just an macro interface to GMP.
1805 Removed the entire GMP from the source tree and imported new
1806 NSS MPI library instead. Reason for removing GMP is that it is
1807 extremely large and compiles extremely slow. The NSS MPI
1808 is only a few files and compiles in less than 10 seconds.
1809 The speed is also about the same as GMP. The MPI is imported
1810 to lib/silcmath/mpi.
1812 If the system has GMP installed we will still use the GMP.
1813 If it is not then the NSS MPI will be compiled.
1815 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Merged a long nickname (127 characters long) crash bugfix from
1818 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1820 * Merged a freed memory reference bugfix from Irssi CVS tree.
1821 Affected file irssi/src/core/commands.c.
1823 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Added the server's public key sving and verification to the
1826 server when performing the SKE. This was missing and the
1827 remote server's (or router's) public key was accepted without
1828 checking whether we have it previously or trust it at all.
1829 Affected file silcd/protocol.c.
1831 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1833 * Check in the silc_server_timeout_remote if protocol is active
1834 and make sure that the protocol's final callback is called so
1835 that all memory if freed. Affected file silcd/server.c.
1837 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1839 * silc_server_whois_send_reply crashed the server if the nickname
1840 was 127 characters long. Affected file silcd/command.c.
1842 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1844 * Added sanity check to the silc_server_new_client. If the hostname
1845 is provided inside username then check that the provided hostname
1846 really is the same as the resolved one. If the hostname was not
1847 resolved then check it from the public key. Affected file is
1848 silcd/packet_receive.c.
1850 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1851 if the server disconnected us and the connection is not valid
1852 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1854 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1855 the library to the lib/silcutil/silcutil.[ch].
1857 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Close log file after open. Affected file
1860 lib/silcutil/silclog.c.
1862 * Check whether sock == NULL in silc_client_send_packet and return
1863 if it is. Affected file lib/silcclient/silcclient.c.
1865 * Check rec->entry == NULL in the Irssi SILC Client before
1866 sending the channel message. Affecte file is
1867 irssi/src/silc/core/silc-servers.c.
1869 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1871 * Merged a splitted window bugfix from Irssi CVS tree. The
1872 affected file is irssi/src/fe-text/textbuffer-view.c.
1874 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1875 It did not print nickname.
1877 * Improved the distributions system a bit.
1879 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1881 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1882 irssi/src/fe-text/gui-window.c.
1884 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1885 to in-active server. The affected file is
1886 irssi/src/silc/core/client_ops.c.
1888 * Resolve the client in USERS command reply if the entry does
1889 not have username resolved. The affected file is
1890 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1891 command to WHOIS command to really resolve stuff. The USERS
1892 is not used any more in any critical section so WHOIS can
1893 be used even though it might be slower than IDENTIFY.
1895 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1898 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Changed the protocol API a bit more consistent in the
1901 lib/silccore/silcprotocol.[ch].
1903 * Changed the following headers to ROBODoc format:
1905 lib/silccore/silcpayload.h
1906 lib/silccore/silcprotocol.h
1907 lib/silccore/silcsockconn.h
1909 All core library headers are now formatted.
1911 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Fixed a bug in Irssi SILC client; do not show that you are
1914 server/router operator if you really are not. Affected file is
1915 irssi/src/silc/core/client_ops.c.
1917 * Renamed silc_command_free_payload to silc_command_payload_free.
1918 Affected file lib/silccore/silccommand.h
1920 * Added silcmath.h to include the prototoypes of various routines
1921 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1924 * Changed the following headers to ROBODoc format:
1926 lib/silccore/silcchannel.h
1927 lib/silccore/silccommand.h
1928 lib/silccore/silcid.h
1929 lib/silccore/silcidcache.h
1930 lib/silccore/silcmode.h
1931 lib/silccore/silcnotify.h
1932 lib/silccore/silcpacket.h
1933 lib/silcmath/silcmath.h
1935 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Added checking to the server code not to start the server if
1938 ciphers and stuff are not configured properly. Affected files
1939 silcd/serverconfig.[h] and silcd/server.c.
1941 * Changed the layout of the header files of the public interfaces
1942 in the SILC libraries. The new layout supports ROBODoc
1943 documentation tool (and some others) so that it is easy to create
1944 a library reference manual. All the other headers and source
1945 code must still follow the CodingStyle document. Also source
1946 code must not include these ROBODoc stuffs, only the headers.
1947 Furthermore, all public interface headers must now be named
1948 by using `silc' prefix, example: silcapi.h, silccipher.h.
1949 Some files were renamed due to this. All the other headers
1950 must not be used as public interfaces. I will update the
1951 CodingStyle document later. Changed following headers, so far:
1953 lib/silcclient/silcapi.h
1954 lib/silccore/silcauth.h
1955 lib/silccore/silcprivate.h
1956 lib/silccrypt/silcdh.h
1958 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Removed silc_client_packet_send_flush from the client library
1963 as it is not needed. Affected file lib/silcclient/client.[ch].
1965 * Added printing of message of unresolved authentication method
1966 to the Irssi SILC client. Added it to the module formats.
1967 Removed the same message from the client library.
1969 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Added new distribution feature, DISTLABEL. Every distribution
1972 can define own preprocessor label that can be used in the
1973 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1974 file distributions, acconfig.h.pre and prepare.
1976 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Added Makefile.defines_int to include the actual definitions
1979 for Makefile.defines.in. Tested the new distribution system,
1980 created distributions and tested installation.
1982 * Added AWAY message printing to the Irssi SILC client. Added
1983 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1985 * Added SCONNECT command to call the SILC's CONNECT command.
1986 Cannot use CONNECT directly since Irssi uses that internally.
1987 Affected file irssi/src/silc/core/silc-servers.c.
1989 Added ACTION local command. It is same as ME command but takes
1990 the channel as mandatory argument.
1992 Rewrote some of the Irssi's help files to suite for SILC
1995 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Added Makefile.defines[.in] that should for now on be included
1998 in all Makefile.am file in the source tree. That file includes
1999 all common compilation definitions for SILC source tree.
2001 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Minor changes to the ./prepare script to change the package
2004 name according the distribution name to the configure.in.
2006 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Created new distribution system. Added file `distributions'
2009 that defines all the distributions that can be created out of
2010 the SILC source tree. The ./prepare script now reads that
2011 file to determine how to prepare the distributions. The
2012 first argument to the ./prepare is the name of the distribution
2013 and second is the version of the distribution. If given
2014 without arguments it creates the default (toolkit) distribution
2015 with the default version (defined in ./prepare).
2017 All Makefile.am files that are subject to the distributions
2018 are now named as Makefile.am.pre. These are ./Makefile.am
2019 and lib/Makefile.am. Others may be changed later.
2021 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Added invite list, ban list, some key management and connection
2024 error message printing to module formats in the Irssi SILC client.
2026 * Added new silc_client_set_away_message to set the away message
2027 that is back to the person who sent private message. The
2028 affected file lib/silcclient/silcapi.h and the
2029 lib/silcclient/client_prvmsg.c.
2031 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2033 * Fixed the private message sending in the Irssi SILC client,
2034 added local command KEY to the Irssi SILC client.
2036 Added key management and key agreement message formats to the
2037 irssi/src/fe-common/silc/module-formats.[ch].
2039 Added USERS (alias WHO) printing, server/router operator
2040 indication and LIST command printing to the module formats.
2042 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Fixed channel joining notify handling, cumode notify handling
2045 from Irssi SILC client.
2047 * Added SILC specific module-formats to the Irssi SILC client so
2048 that SILC specific message hilighting, colors etc is possible.
2049 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2051 Added channel mode, channel user mode, actions, notices,
2052 whois and whowas printing to the the module-formats.c.
2054 * Fixed a bug in channel deletion in the server. The channel
2055 is not left to the cache even if the channel founder auth mode
2056 is set when there are no users anymore on the channel. Affected
2057 file silcd/server.c.
2059 * The silc_net_localhost now resolves the entire hostname including
2060 the domain name. Affected file lib/silcutil/silcnet.c.
2062 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Changed the ask_passphrase client operation to be ascynchronous.
2065 It has now a completion callback and a context that the
2066 application must call after it has got the passphrase from
2067 the user. Affected files lib/silcclient/silcapi.h,
2068 lib/silcclient/protocol.c, lib/silcclient/command.c and
2071 Added SilcAskPassphrase callback that the application calls
2072 to deliver the passphrase to the library.
2074 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2075 The public key verification and especially a certificate
2076 verification is asynchronous procedure.
2078 Added new SILC_SKE_STATUS_PENDING status to indicate the
2079 request is pending and a callback will be called to finalize
2082 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2083 indicate that remote end did not send its public key (or
2084 certificate), even though we require it. Added check for this
2085 condition in the SKE. This was a security bug, now fixed.
2087 Defined new SilcSKEVerifyCbCompletion callback that is called
2088 when the verification process is completed.
2090 The affected files lib/silcske/silcske_status.h and
2091 lib/silcske/silcske.[ch].
2093 * Changed the verify_public_key client operation to be async
2094 as well. Defined SilcVerifyPublicKey callback that is used to
2095 indicate the success of the public key verification process.
2097 Changed the server and client to use the new async client
2100 * Changed the Irssi SILC client's internal scheduler to be called
2101 twice as many times as it used to be. As a result the client
2102 should be a bit faster now. Affected file is
2103 irssi/src/silc/core/silc-core.c.
2105 * Added support to Irssi SILC client of asynchronous public key
2106 verification and passphrase inquiry. Affected file is
2107 irssi/src/silc/core/silc-core.c.
2109 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2111 * Do not say "You have left channel %s" in client library.
2112 Moved it to the application. Affected files are
2113 lib/silcclient/command.c and silc/client_ops.c.
2115 * Fixed silc_client_get_clients. Command context was not
2116 duplicated and was freed memory in the callback. Affected
2117 file lib/silcclient/idlist.c.
2119 * Do not say "you are now talking..." on JOIN command in the
2120 client library. The appliation must handle it.
2122 * Do not say ".. changed topic to" in command reply in the
2123 client libary. The application must handle it.
2125 * Fixed TOPIC command sending in the client library.
2127 * Fixed a memory leak in silc_client_command_free in the file
2128 lib/silcclient/command.c.
2130 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Imported a modified version of Irssi client to the source tree.
2133 The Irssi will be used to create a new client called
2134 Irssi SILC. Imported to irssi/.
2136 Added silc_core_init_finish function to the Irssi. Affected
2137 file irssi/configure.in.
2139 A lot changes in the Makefile.ams around the irssi tree.
2141 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Do not rehash if the new size is same as the old size of the
2144 hash table, in the silc_hash_table_rehash*. The affected file
2145 lib/silcutil/silchashtable.c.
2147 * Replaced hash_table_del_by_context calls from the server
2148 (when channel->user_list and client->channels) to the
2149 hash_table_del as it is sufficient and faster.
2151 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Added silc_hash_table_list, silc_hash_table_get and the
2154 SilcHashTableList structure to provide an alternative way to
2155 traverse the hash table. The affected files are
2156 lib/silcutil/silchashtable.[ch].
2158 * Changed the server's idlist routines to use the hash table
2159 routines to optimize the code.
2161 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Replaced the client entry's `channel' list and channel entry's
2164 `user_list' list to hash tables for optimized lookup. Changed
2165 the code to use the hash table interface around the code.
2166 Affected file lib/silcd/idlist.[ch].
2168 * Added `auto_rehash' boolean argument to the function
2169 silc_hash_table_alloc to indicate whether the hash table should
2170 auto-rehash when it thinks is appropriate time. It will
2171 increase the hash table size if the there is twice as much
2172 entries in the table than the size of the table, and will
2173 decrease the size if there are twice as less entries than
2174 the size of the table.
2176 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2180 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * silc_idcache_purge_by_context deletes the entry now by context
2183 as it is supposed to do. Affected file lib/silccore/idcache.c.
2185 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2186 client is not anymore valid (WHOWAS givens the info) and not
2187 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2189 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2191 * Removed the `data' and `data_len' arguments from the ID Cache
2192 interfaces and added `name' argument. ID Cache does not handle
2193 anymore the binary data only a names associated with given ID.
2195 * When hashing a Client ID with silc_hash_id the entire ID is
2196 not hashed anymore, instead only the hash of the Client ID is
2197 hashed. This way we can access the Client ID from the cache
2198 with Client ID but with the hash of the ID (which is a hash of
2199 the nickname) as well without any difference in performance.
2201 Added also silc_idcache_find_by_id_one_ext to do one on one
2202 searching when we have the actual ID. Added also function
2203 silc_hash_client_id_compare. The affected files are
2204 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2206 * When hashing the name associated with a ID it is always done
2207 in lowercase. This way we can access the cache without worrying
2208 about case-sensitivity, even though, for example nicknames are
2211 * Fixed a bug in server with channel message sending. It put
2212 wrong ID type as destination ID. The affected file
2213 silcd/packet_send.c.
2215 * silc_idcache_del_by_context now deletes from all hash tables
2216 by context. Affected file lib/silccore/idcache.c.
2218 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Changed the client library to use the new ID Cache interface.
2221 Changes around the source tree.
2223 * Added silc_hash_table_rehash_ext to rehash with specific
2224 hash function. Affected file lib/silcutil/silchashtable.[ch].
2226 * Added silc_hash_string_compare to compare two strings in the
2227 hash table. Affected file lib/silcutil/silcutil.[ch].
2229 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Added new function silc_idcache_del_by_context into the
2232 lib/silccore/idcache.[ch].
2234 * Changed the server's ID list routines to use the new ID Cache
2235 interface. Changes around the source tree.
2237 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2239 * Added silc_hash_table_del[_by_context]_ext functions in to the
2240 lib/silcutil/silchashtable.[ch].
2242 Removed silc_hash_table_find_all* routines and added new
2243 silc_hash_table_find_foreach to replace them.
2245 Added silc_hash_table_replace_ext function as extended
2246 replacing function. Separated the simple hash table interface
2247 from the extended hash table interface in the file
2248 lib/silcutil/silchashtable.h.
2250 * Fixed minor bugs and changed it to use some of the new
2251 hash table functions in lib/silccore/idcache.c
2253 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Added new function silc_hash_table_find_all to return all keys
2256 in the hash table by the specified key. As the hash table is
2257 collision resistant it also makes it possible to have several
2258 duplicate keys in the hash table. This function may be used to
2259 find all of the keys from the hash.
2261 Added user_context arguments to the SilcHashFunction,
2262 SilcHashCompare and SilcHashDestructor to deliver user specified
2265 Added new fuctions silc_hash_table_find[_all]_ext to do
2266 extended lookup with specified hash and compare functions and
2267 specified user contexts.
2269 Added new function silc_hash_table_add_ext to add the key
2270 with specified hash function and user context.
2272 Added new function silc_hash_table_foreach to traverse all
2273 entrys in the hash table. Added SilcHashForeach callback
2276 Added new function silc_hash_table_del_by_context to delete
2277 the entry only if the context associated with the key matches.
2279 Affected files are lib/silcutil/silchashtable.[ch].
2281 * Removed silc_hash_[server/client/channel]_id and added just
2282 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2283 silc_hash_id_compare to compare two ID's using as the hash table
2284 comparison function. Added also silc_hash_data to hash
2285 binary data and silc_hash_data_compare to compare it.
2287 * Removed silc_idlist_find_client_by_hash as it is not needed
2288 anymore. Affected file silcd/idlist.[ch].
2290 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2291 to use internally the SilcHashTable. The new ID Cache is a lot
2292 faster than the old one. Some of the ID Cache interface was also
2293 rewritten and obsolete and stupid functions were removed.
2295 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Added entry_count field to the SilcHashTable to keep the number
2298 of the entries in the table. Implemented the function
2299 silc_hash_table_rehash. Added new function
2300 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2302 Fixed a minor bug in silc_hash_table_free.
2304 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2305 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2306 into the lib/silcutil/silcutil.[ch].
2308 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Implemented a collision resistant hash table into the
2311 lib/silcutil/silchashtable[ch]. See the header and the source
2312 for the SilcHashTable API.
2314 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2316 * Merged dotconf version 1.0.2 into lib/dotconf.
2318 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2320 * Do not compile anything in lib/silcsim/* if the SIM support
2321 is not enabled. The tree should now compile without problems
2324 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2326 * Compiled the SILC under cygwin. Compiled and tested briefly
2327 without problems. More tests needed. The SIMs didn't compile
2330 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2332 * Fixed possible crash in silc_get_username in the
2333 lib/silcutil/silcutil.c.
2335 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2337 * Fixed a va_arg in silc/client_ops.c.
2339 * Oops, RC5 routines were named AES and caused some problems
2340 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2342 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2344 * Added new SilcIDIP structure into the lib/silccore/id.h and
2345 replaced the old `ip' fields from all SILC ID's to that type.
2346 This is a step towards IPv6 support.
2348 The silc_id_get_len takes now the ID as an extra argument.
2349 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2350 both IPv4 and IPv6 based ID's.
2352 The affected files are lib/silccore/id.[ch] and other files
2353 around the tree using these routines.
2355 * Removed the ID length arguments in server from various
2356 silc_server_send_notify_* routines -> they are not needed
2359 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2361 * Fixed memory leak in silc_encode_pem_file in the file
2362 lib/silcutil/silcutil.c.
2364 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2366 * Check minor version as well in the SKE. Affected files are
2367 silcd/protocol.c and lib/silcclient/protocol.c.
2369 * Added --identifier option to the server so that an identifier
2370 can be when creating the public key for the server. Affected
2371 file is silcd/silcd.c.
2373 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2374 lib/silccrypt/silcpkcs.c.
2376 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Register default ciphers and stuff when using -C option with
2379 the server. Affected file sildc/silcd.c.
2381 * Put back the servers public key filename format, it is better
2382 than the new one. For now, the client keys are saved with the
2383 new filename format. The affected file silc/client_ops.c.
2385 * Implemented the Cipher API for the rest of the ciphers that
2386 did not implement it or implemented it the wrong way.
2388 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Register default ciphers and stuff when using the -S option
2391 in the client. Affected file silc/silc.c. Same also when
2392 creating new key pair with -C option.
2394 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Fixed the silc_verify_public_key client operation function to
2397 save the public keys differently. The fingerprint is now
2398 used as filename and not the hostname. This way also the
2399 client keys are saved uniquely and not with hostnames. The
2400 affected file is silc/client_ops.c.
2402 * Trimmed the silc_hash_fingerprint function to remove extra
2403 whitespaces from the end of the fingerprint. The affected
2404 file is lib/silccrypt/silchash.c.
2408 * Added silc_cipher_register_default function to register all
2409 default ciphers. It can be used when configuration files
2410 does not exist and the application does not want any specific
2411 ciphers in any specific order.
2413 The SilcDList is now used as silc_cipher_list dynamically
2414 allocated cipher list. Removed the static list all together
2415 and now all ciphers must be allocated to the dynamic list.
2416 The silc_cipher_alloc routine was changed to check only the
2419 All silc_cipher_* routines that used to return int returns
2422 The affected files lib/silccrypt/silccrypt.[ch].
2424 * The same thing was done to silc_hash_* as for silc_cipher_*
2425 routines. Affected files lib/silccrypt/silchash.[ch].
2427 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2428 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2429 Added also silc_pkcs_[un]register[_default] functions.
2430 Removed the data_context from the PKCS API.
2432 * Added silc_hmac_register_default function to register default
2433 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2434 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2435 to unregister all hmacs at once.
2437 * Register the default ciphers, hash functions, PKCSs and HMACs
2438 if client's configuration file does not exist. The affected
2441 * The client did not load the hash functions from the SIM
2442 modules at all. Added support for this. Affected file is
2443 silc/clientconfig.c.
2445 * When decoding public key with silc_pkcs_public_key_decode, check
2446 the supported algorithm only if PKCS are registered. Affected
2447 file lib/silccrypt/silcpkcs.c. The same was done with the
2448 silc_pkcs_private_key_decode.
2450 * Fixed the SILC List routines to keep the list always in order.
2451 It used to change the list's order when traversing the list but
2452 not it preserves the order. Affected file lib/trq/silclist.h.
2454 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2456 * Added the client library to use the SilcSocketConnection's
2457 reference counter (by silc_socket_dup) to prevent the bug that
2458 the socket object may be freed underneath async operation.
2460 * The name resolv library checking fixes in the configure.in.pre.
2463 * Created new version of the protocol drafts for future
2464 development. The -03 drafts are the ones that will be changed
2465 in the trunk now and the -02 will remain as they are.
2467 * Send list of CUMODE notifys to the router when announcing
2468 the channel users to the router. Affected file silcd/server.c.
2469 If the router receiving channel founder CUMODE for a channel
2470 that already has channel founder it will send CUMODE notify
2471 to the sender to remove the channel founder rights from the
2472 announced client. Affected file silcd/packet_receive.c.
2474 * The CUMODE notify may now use Server ID as well as the entity
2475 who changes the mode. Updated protocool specs.
2477 * Updated INSTALL and README files.
2479 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * New web pages in the http://silc.pspt.fi. The pages was
2486 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * Implemented the [DenyConnectin] config section in the server.
2489 Added silc_server_config_denied_conn to check whether incoming
2490 connection is denied. Affected file silcd/serverconfig.[ch].
2492 * Do not check the ports when checking the incoming configuration
2493 data if the port is 0, meaning any. Affected file is
2494 silcd/serverconfig.c.
2496 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Fixed buffer overflow in silc_string_compare in the file
2499 lib/silcutil/silcutil.c.
2501 * Fixed double free in silc_server_command_leave in the file
2504 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Fixed the version checking in the server. Affected file is
2509 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Fixed the configuration data fetching when accepting new
2512 connections in the server. Affected file silcd/server.c.
2514 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Added `sender_entry' argument to the function
2517 silc_server_packet_relay_to_channel so that we can check
2518 whether some destination actually belongs to the same route
2519 the sender belongs (ie, we must not resend the packet to the
2520 sender). Affected file silcd/packet_send.[ch].
2522 * Added `servername' field to the SilcClientEntry in the server
2523 to hold the name of the server where client is from. Affected
2524 file is silcd/idlist.h.
2526 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Moved the channel message encrypting in the router betwen
2529 router connections from silc_server_channel_message to the
2530 silc_server_packet_relay_to_channel since we want to check
2531 whether we have anybody channel before encrypting anything.
2532 Affected files silcd/packet_[receive/send].c.
2534 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Fixed the [AdminConnection] server config section to support
2537 multiple entries. Affected file silcd/serverconfig.c.
2539 * Added support into the server to check the validity of the
2540 incoming connection before executing any KE or authentication
2543 * The connection configuration is now saved to the KE and
2544 connection auth protocol contexts and not fetched anymore in
2545 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2547 * The local hosts listenning address and port is also resolved
2548 now when starting the server. We want to have the socket object
2549 to include the real address and port for the listener. Added
2550 new function silc_net_check_local_by_sock into the files
2551 lib/silcutil/silcnet.[ch].
2553 * Fixed a broadcast bug in server -> do not broadcast if we
2556 * Fixed a routing bug. Do not route broadcast packets ever.
2557 Broadcast packets must be processed always and not routed since
2558 they may be destined to some other host than yourself and thus
2559 would get routed without no good reason. Affected file is
2562 * Added function silc_server_config_is_primary_route to check
2563 whether primary router connection has been configured (a router
2564 configuration that we are initiating). If there is not, we
2565 will assume that there is only two routers in the SILC network
2566 and we will use the incoming router connection as our primary
2567 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2569 * Changed the order of the broadcasting. Broadcast _after_ the
2570 packet has been processed not before. Affected file is
2573 * Fixed a [ClientConnection] parsing bug. The port was never
2574 parsed correctly thus resulting to port 0. Affected file
2575 silcd/serverconfig.c.
2577 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2578 argument and did not set the broadcast packet flag. Affected
2579 file silcd/packet_send.c. Fixed same bug in the function
2580 silc_server_send_notify as well.
2582 * If we receive NEW_ID packet for our own ID in the server, ignore
2585 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Removed the nickname from the Private Message Payload.
2590 Updated the code and the protocol specs.
2592 * Updated protocol specs for submitting to the IETF.
2594 * Tweaked the Random Number Generator a bit. Affected file
2595 lib/silccrypt/silcrng.c. Exported a new function
2596 silc_rng_[global]_add_noise which can be used to add more
2599 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Do not parse packets with different timeout when protocol
2602 is active -> may cause problem with rekey. Affected file
2605 * When server receives signoff notify it must not create
2606 new channel key if the client is on any channels since the
2607 sender of the signoff notify will create it.
2609 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2611 * Added printing of error messages during SKE protocol from the
2612 failure packet sent by server during SKE. Affected file
2615 * Removed the client's failure_callback handling with timeout
2616 and handle it immediately when received.
2618 * The SKE library returned wrong type in SUCCESS and FAILURE
2619 packets. They must be 32 bit MSB not 16 bit MSB.
2621 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Ok, rewrote the logic of the re-key and now it seems to work.
2624 I tested it on high traffic with frequent re-keys without
2625 problems. Added hmac_receive (and renamed hmac to hmac_send)
2626 in SilcClientConnection in lib/silcclient/client.h and
2627 in SilcIDListData in silcd/idlist.h. Also, removed the
2628 SilcPacketParserContext's cipher and hmac fields as they are
2629 not needed anymore and actually caused some problems when
2630 the ciphers and hmac's changed underneath the packet parser.
2632 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * If re-key protocol is active then process the incoming packets
2635 synchronously since we must assure that icoming packets encrypted
2636 with the old key is processed before the new keys is set to
2637 use. This is true other packets than for REKEY packets.
2638 Affected file silcd/server.c. The same was done to client library
2639 as well, affected file lib/silcclient/client.c.
2641 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2643 * Fixed bug in client and server to accept the force send if
2644 the packet is send from silc_[server/client]_packet_process
2645 function. Otherwise the packets are never delivered, oops.
2647 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Disable force sending of packets when REKEY protocol is active.
2650 We must assure that no packet is sent directly when rekey is
2651 performed. All packets must be sent through packet queue.
2652 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2653 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2654 function is silc_[server/client]_packet_send_real to check
2657 * Replaced the SIM paths from example config files to
2658 /usr/local/modules. Also, make install creates now
2659 /usr/local/silc/logs directory to hold all the SILC server
2662 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Made the configure.in.pre work on Solaris. Patch by salo.

2673 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * When MAC computation fails the silc_packet_decrypt returned 0
2676 even though it was supposed to return -1. Fixed this. The
2677 affected file is lib/silccore/silcpacket.c.
2679 * Do not replace the config files in /etc/silc (in make install)
2680 if they already exist. Affected file ./Makefile.am.
2682 * Do not send re-key packets immediately but through packet queue.
2683 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2685 * Changed silc_net_check_host_by_sock to return FALSE if the
2686 IP/DNS could not be resolved. Though, it returns the IP address
2687 now even if it could not resolve it (but returns also FALSE).
2688 Affected file lib/silcutil/silcnet.[ch].
2690 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Added silc_pkcs_decode_identifier to decode the public key's
2693 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2694 Added also silc_pkcs_free_identifier. Added also new context
2695 SilcPublicKeyIdentifier.
2697 * Added -S option to the silc client. It is used to dump the
2698 contents of the specified public key file.
2700 * Changed the PKCS api to return the public key length when
2701 setting the public key.
2703 * Fixed a fatal bug in the public and private key file loading.
2704 Affected file lib/silccrypt/silcpkcs.c.
2706 * Execute the packet parsing for client with zero (0) timeout
2707 if the protocol is active. Affected file silcd/server.c.
2709 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * Made the key generation options to the silcd program. Added
2712 -C option, equivalent to client's option.
2714 * Added new [ServerKeys] config section to the server. It
2715 configures the server's public and private key.
2717 * Defined generic Public Key Payload into the protocol
2718 specification to send specific type of public keys and
2721 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2722 public key or certificate.
2724 * Implemented the GETKEY command to the server and to the
2725 client library and on user interface.
2727 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Made preliminary `make install' work.
2731 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Added SilcServerRekey context into silcd/idlist.h.
2735 * Added the PFS support as defined in the specification to the
2736 SKE protocol. Affected files lib/silcske/*.c.
2738 * Added `ske_group' field to the SilcServerRekey context to hold
2739 the number of the SKE group that is used with PFS in re-key.
2740 Affected file silcd/idlist.h.
2742 * Added PFS re-key support to the server. Affected file is
2745 * Added silc_protocol_cancel to cancel execution of the next
2746 state of the protocol. Affected file is
2747 lib/silccore/silcprotocol.[ch].
2749 * Added the re-key support with and without PFS to the client
2750 library. Re-key is performed once in an hour, by default.
2752 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2753 Added silc_client_rekey_callback and silc_client_rekey_final.
2754 Affected files are lib/silcclient/protocol.[ch] and
2755 lib/silcclient/client.[ch].
2757 * Removed the `hmac_key' and `hmac_key_len' fields from the
2758 SilcClientConnection structure; not needed. Affected file is
2759 lib/silcclient/client.h.
2763 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * Do not ask whether user wants to use the negotiated private key
2766 for private messages, just use it. Affected file is
2767 silc/local_command.c.
2769 * Added `send_enc_key' and `enc_key_len' fields to the
2770 SilcIDListData structure since they are needed in the re-key
2771 phase. Affected file is silcd/idlist.[ch].
2773 * Implemented the simple re-key protocol into the server.
2774 Affected files silcd/server.c and silcd/protocol.[ch]. The
2775 re-key will be performed once in an hour, by default.
2777 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2778 Added silc_server_rekey, silc_server_rekey_callback and
2779 silc_server_rekey_final.
2781 * Removed Tunneled flag from the protocol. Updated the code
2782 and the specifications.
2784 * Adde `pfs' field to the SilcIDListData to indicate whether
2785 the PFS is to be performed in the re-key. Affected file is
2788 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2790 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2791 int64 of at least the xintXX size. If void * is less that 4
2792 bytes uint32 * will be used. Defined bool as boolean.
2794 * Changed _ALL_ unsigned long and unsigned int to uint32,
2795 unsgined short to uint16 in the source tree.
2797 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2798 not handle clients that has entry->data.registered == FALSE.
2799 They are not in the network anymore. Affected file is
2802 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2804 * Implemented the sending of the SERVER_SIGNOFF notify in the
2805 server. Affected file is silcd/server.c.
2807 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2808 Added also silc_notify_payload_encode_args into the
2809 lib/silccore/silcnotify.[ch].
2811 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2812 Affected file silcd/packet_receive.c.
2814 * Implemented the SERVER_SIGNOFF notify handling in the client
2815 library. Affected file lib/silcclient/client_notify.c. Also,
2816 implemnted the printing of the SERVER_SIGNOFF info to the
2817 application. Affected file silc/client_ops.c.
2819 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2820 if the deleting was successful. Affected file silcd/idlist.[ch].
2822 * Added support for public key authentication in the connection
2823 authentication protocol in the client library. Affected file
2824 lib/silcclient/protocol.c.
2826 * Changed the server's silc_idlist_get_clients_by_* interface
2827 to support already allocated array so that new entries may be
2828 added to pre-allocated array. Affected file silcd/idlist.[ch].
2829 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2830 and command replies.
2832 * All command reply functions in the server now calls the
2833 pending command callback even if error occured. This way the
2834 error will be delivered to the client as well. Affected files
2835 silcd/command.c and silcd/command_reply.c.
2837 * Fixed INFO command to return local server's info if no server
2838 was provided. Affected file lib/silcclient/command.c.
2840 * Removed RESTART command for good. Updated the code and the
2843 * Rewrote parts of the task system. It is a bit simpler now.
2844 Removed unsued task priorities. The affected files are
2845 lib/silcutil/silctask.[ch].
2847 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2849 * Moved the USERS printing from the library to the application.
2850 Affected files lib/silcclient/command.c and silc/client_ops.c.
2852 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2856 * Added channel key re-key support. The re-key is perfomed
2857 only by the router and is done once in an hour. Added `rekey'
2858 field to the SilcChannelEntry in the server. Affected files
2859 silcd/server.c and silcd/idlist.h.
2861 * Added silc_task_unregister_by_context into the file
2862 lib/silcutil/silctask.[ch].
2864 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Added SILC_UMODE_GONE mode to indicate when the client is not
2867 present in the SILC network. Added also support to the local
2868 command AWAY that will set this mode. Added support of showing
2869 "xxx is gone" in WHOIS command. The USERS command shows the
2870 gone status as well.
2872 * Fixed setting server and router operator privileges in the
2873 server's UMODE command. Affected file silcd/command.c.
2875 * Merged the SKE KE1 and KE2 payloads into one payload. The
2876 new KE payload is equivalent to the old KE2 payload.
2878 Cleaned up the SKE Start Payload parsing. It now uses the
2879 simple buffer unformatting to do the parsing. A lot faster
2882 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2883 to the SKE that is used to indicate whether both of the SKE
2884 parties should perform authentication. By default only the
2885 responder performs authentication. By setting this flag also
2886 the initiator must do authentication. By default it is unset
2887 since in normal SKE case, client to server connection, only
2888 the responder should do authentication. When doing SKE between
2889 two clients both should perform authentication. Updated the
2890 code and the protocol specs.
2892 * A little fix to IDENTIFY command in the server. Search the
2893 client first by hash not nickname. Affected file is
2896 * Fixed the silc_client_close_connection to support closing
2897 the client to client connections wihtout deleting too much
2898 data. Affected file lib/silcclient/client.c.
2900 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2901 are received if protocol used to be active but is not anymore
2902 the application would crash due to NULL pointer dereference.
2903 Affected files silcd/server.c and lib/silcclient/client.c.
2905 * Added `hash' field to the SilcClientConnection to include
2906 the hash function negotiated in the SKE protocol.
2908 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2909 to set the channel founder authentication data. A client can
2910 claim the founder rights later by providing the authentication
2911 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2912 This way the channel founder can regain the channel founder
2913 privileges even it is left the channel. This works only on
2914 local server and the client must be connected to the same
2915 server to be able to regain the founder rights. Updated the
2916 protocol specs accordingly.
2918 Added support to the CMODE command in the client to set the
2919 founder auth data. Read the README to see how to set it.
2921 Added support to the CUMODE command to claim the founder
2922 rights. Read the README to see how to do it.
2924 Added support for the founder authentication to the Channel
2925 Entry in the server. Affected file silcd/idlist.h.
2927 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2928 server's CMODE command. Affected file silcd/command.c.
2930 * Added the following new functions into lib/silccore/silcauth.[ch]:
2931 silc_auth_get_method and silc_auth_get_data.
2933 * The server now saves the remote hosts public key to the
2934 SilcIDListData pointer. Affected file silcd/protocol.c.
2936 * The normal server now does not remove the channel entry from
2937 the cache if the founder authentication data is set. It used
2938 to remove it if the founder was the last one on the channel on
2939 the server and left the channel. The auth data is saved and
2940 if the channel is re-joined later the old entry is used with
2941 the old auth data. Affected files silcd/command_reply.c and
2944 * Removed the `pkcs' field from the SilcIDListData structure
2945 in the server; it is not used. Affected file silcd/idlist.h.
2947 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2949 * Fixed packet processing on slow links. Partial packets were
2950 never re-processed because the incoming data buffer was cleared
2951 by the application. Application must not directly clear the
2952 sock->inbuf, the packet processing routines handle it. Fixed
2953 this in client library and in server.
2955 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Fixed the WHOIS and IDENTIFY send reply function to really
2958 check whether to send list or just one entry. Affected file
2961 * Cleaned up the LEAVE command's channel key distribution. The
2962 affected file silcd/command.c.
2964 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2965 can enforce the channel mode as well. In that case the ID
2966 includes the ID of the server. The code now enforces the
2967 mode change if the router have different mode than the server.
2969 * The notify client operation with CMODE_CHANGE notify can now
2970 return NULL client_entry pointer if the CMODE was not changed
2971 by client. Application must check for this.
2973 * Added <Server ID> argument to INFO command to support server
2974 info fetching by Server ID.
2976 * Added silc_server_announce_get_channel_users to get assembled
2977 packets of channel users of the specified channel. Affected
2978 file silcd/server.[ch].
2980 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2981 was freed underneath the ID Cache.
2983 * Re-announce clients when the server received CHANNEL_CHANGE
2984 notify from the router. Affected file silcd/packet_send.c.
2986 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2989 crashed since it did not handle the fact that there is no cipher
2990 called "3" and didn't check the error condition. Now fixed.
2992 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2993 flag. It can be used to send message requests.
2995 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Implemented the RESTART command in the client.
2999 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3000 notice type messages. Added notice printing to the user
3003 * The channel keys are not re-generated if the channel's mode
3004 is PRIVKEY, ie private key on the channel exists. Affected
3005 files silcd/server.c and silcd/command.c.
3007 * Fixed a little bug in channel message delivery when channel
3008 private keys are set in the server. Affected file is
3009 silcd/packet_send.c.
3011 * Changed the setting on channel->on_channel = TRUE from the
3012 silc_client_save_channel_key to the JOIN command reply. The
3013 key payload is not received if the private channel key is set.
3014 Affected file lib/silcclient/command_reply.c and the
3015 lib/silcclient/client_channel.c.
3017 * When the CMODE_CHANGE notify is sent and the channel private
3018 key mode is removed the channel key must be re-generated in
3019 other cells as well. Added this support for the router in the
3020 silcd/packet_receive.c.
3022 * Added new local command NOTICE to send notice message on
3023 channel. Affected file silc/local_command.[ch].
3025 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Added new local command ME to the client. It is used to send
3028 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3029 some action. Affected file silc/local_command.[ch].
3031 * Changed channel_message and private_message client operations
3032 to deliver the message flags to the application. Added also
3033 the `flags' arguments to the silc_client_send_channel_message
3034 and silc_client_send_private_message functions. Affected file
3037 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3039 * Redefined the Private Message Payload to support private message
3040 keys and to support the new private message flags. Updated
3041 the protocol specs. Flags makes it possible to have for example
3042 CTCP style messages.
3044 * Added new type SilcPrivateMessagePayload and defined an API
3045 for it in the lib/silcclient/silcprivate.[ch].
3047 * Tested private message private keys successfully. Tested the
3048 private message key set, unset and list commands with the new
3051 * Redefined the Channel Message Payload to include the channel
3052 message flags (equal with private message flags) to support
3053 for example CTCP style messages.
3055 * Defined some of the message (for channel and private message)
3056 flags. Updated the protocol specs and added the flags to the
3057 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3059 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Added SilcKeyAgreementStatus type to the key agreement routines
3062 to indicate the current status and error if one occured.
3063 The status types are defined in the lib/silcclient/silcapi.h.
3065 * Added new local command KEY that is used to set and unset private
3066 keys for channels, set and unset private keys for private messages
3067 with remote clients and to send key agreement requests and
3068 negotiate the key agreement protocol with remote client. The
3069 key agreement is supported only to negotiate private message keys,
3070 it currently cannot be used to negotiate private keys for channels,
3071 as it is not convenient for that purpose.
3073 * Fixed a minor pending callback setting bug in the function
3074 silc_client_get_client_by_id_resolve, now the function works.
3075 Affected file lib/silcclient/idlist.c.
3077 * Added function silc_net_get_local_port to get local bound
3078 port by socket. Added to lib/silcutil/silcnet.[ch].
3080 * Added `sockets' and `sockets_count' fields to the SilcClient
3081 object. They hold the sockets of the listenning sockets in
3082 the client. Listenning sockets may be for example the key
3083 agreement server. Affected file lib/silcclient/client.[ch].
3084 Added functions the silc_client_add_socket and the
3085 silc_client_del_socket. They are exported to the application
3088 * Added ~./silc/clientkeys to support other client's public keys.
3090 * Renamed verify_server_key client operation to verify_public_key
3091 and added one argument to indicate the type of the connection
3092 (server, client etc.).
3094 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3096 * Added silc_server_connection_auth_request to handle the
3097 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3098 silcd/packet_receive.[ch].
3100 * Added silc_server_send_connection_auth_request into the
3101 silcd/packet_send.c to send the connection auth request packet.
3103 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3106 * Fixed the public key authentication in responder side in the
3107 server. The `auth_data' pointer includes the SilcPublicKey
3108 not the path to the public key. Affected file silcd/protocol.c.
3110 * Implemented the public key authentication in the initiator side
3111 in the server. Affected file silcd/protocol.c.
3113 * Removed the [RedirectClient] config section from the server
3114 configuration. Is not needed and I don't want to implement it.
3116 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Cleaned up the CMODE command in the server. It now works
3119 correctly and supports all the modes defined in the protocol.
3120 Affected file is silcd/command.c.
3122 * Added `hmac_name' field to the SilcChannelEntry in the server
3123 to hold the default HMAC of the channel. It can be set when
3124 creating the channel (with JOIN command). Affected files
3127 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3128 type to indicate the change of the current cipher and hmac
3129 on the channel. Client can safely ignore the <cipher> argument
3130 (if it chooses to do so) since the CHANNEL_KEY packet will
3131 force the channel key change anyway. The <hmac> argument is
3132 important since the client is responsible of setting the new
3133 HMAC and the hmac key into use.
3135 * Fixed the CMODE command in the client library as well.
3137 * Tested CMODE command in router environment successfully.
3139 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3141 * Show the version of the remote client (or server) when connecting
3142 to the server. It is logged to the log file. Affected file
3143 is silcd/protocol.c.
3145 * Fixed the KILLED notify handling in the client library. The
3146 client must be removed from all channels when receiving the
3149 Also, do not remove the client entry when giving the KILL
3150 command but when the KILLED notify is received.
3152 * Removed silc_idlist_find_client_by_nickname from the server.
3153 Not needed anymore. Affected files silcd/idlist.[ch].
3155 * Implemented the CHANNEL_CHANGE notify type handling to the
3156 server. Affected file silcd/server.c.
3160 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Added silc_server_send_notify_invite to send the INVITE
3163 notify between routers.
3165 * Implemented the INVITE command correctly to the server.
3167 * Implemented the INVITE notify type handling in the server.
3169 * Implemented the INVITE command to the client library and on the
3172 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3174 * Added function silc_server_get_client_resolve to find the
3175 client entry by ID from all ID lists and then resolve it
3176 (using WHOIS) if it cannot be found. Affected file is
3179 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3181 * Implemented the BAN command to the client library.
3183 * The JOIN command in the server now checks the invite list
3186 * Changed the silc_command_reply_payload_encode_va and the
3187 silc_command_payload_encode_va to support that if argument is
3188 NULL it ignores and checks the next argument. Affected file
3189 lib/silccore/silccommand.c.
3191 * Added silc_server_send_notify_ban to send the BAN notify
3192 type between routers.
3194 * Chaned the silc_notify_payload_encode to support that if
3195 argument is NULL it ignores and checks the next argument.
3196 Affected file lib/silccore/silcnotify.c.
3198 * Tested ban lists in router environment successfully.
3200 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3202 * Implemented BAN command to the server, in silcd/command.[ch].
3204 * Removed the BAN and INVITE_LIST modes from the CMODE command
3207 * Added function silc_string_match to regex match two strings.
3208 Affected files lib/silcutil/silcutil.[ch].
3210 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3212 * Redefined parts of the SilcChannelEntry in the server to support
3213 the new ban and invite lists.
3215 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3217 * Redefined the INVITE command. The same command can be used to
3218 invite individuals to the channel but also to manage the invite
3219 list of the channel (to add to and remove from the invite list).
3220 Updated the protocol specs.
3222 * Added new command SILC_COMMAND_BAN that can be used to manage
3223 the ban list of the channel. Updated the protocol specs.
3225 * Removed the channel modes: the SILC_CMODE_BAN and the
3226 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3227 in the CMODE command. The equivalent features are now available
3228 using INVITE and BAN commands. Updated the protocol specs.
3230 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3231 in the network about change in the current ban list. The notify
3232 type is not used by the client.
3234 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3235 support the invite lists.
3237 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Added new function silc_string_regexify that converts string
3240 including wildcard characters into regex string that can
3241 be used by the GNU regex library. Added into the file
3242 lib/silcutil/silcutil.[ch].
3244 Added silc_string_regex_combine to combine to regex strings
3245 into one so that they can be used as one regex string by
3246 the GNU regex library. Added into the file
3247 lib/silcutil/silcutil.[ch].
3249 Added silc_string_regex_match to match two strings. It returns
3250 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3252 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3254 * Imported GNU regex to the soruce tree into lib/contrib.
3255 Fixed some compiler warning from the regex.c.
3257 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Fixed MOTD command in the server to work in router environment.
3261 * Fixed the MOTD command in the client library to support
3262 the server argument in the command.
3264 * Added `nickname_len' argument to the silc_idlist_add_client
3265 in the server, as the `nickname' argument may be binary data
3268 * Added silc_idlist_get_channels to return all channels from
3271 * Implemented LIST command to the server. Affected file is
3274 * Implemented the LIST command to the client library and on the
3277 * Added [<user count>] argument to the LIST command reply.
3278 With private channels the user count is not shown.
3280 * Updated TODO and README.
3282 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * The client entry's data.registered must be TRUE even with
3285 global client entry on global client list. The data.registered
3286 is used to check whether the client is anymore in the network,
3287 for example with WHOWAS command so it must be valid.
3289 * Fixed the WHOWAS command in the server. It now actually works
3290 in router environment. Added function into silcd/command_reply.c
3291 silc_server_command_reply_whowas_save.
3293 * Added silc_idlist_purge function to the silcd/idlist.c
3294 to periodically purge the ID Cache.
3296 * Fixed INFO command in the server. It works now in router
3297 environment. Added <server name> argument to the INFO command
3298 reply. Updated the protocol specs.
3300 * Fixed minor bug in silc_idcache_purge to not purge if the
3301 expire value is zero.
3303 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3304 they were buggy because of the WHOWAS information.
3306 * Fixed local command MSG to handle the async resolving of
3307 the remote client properly. It used to fail the first MSG.
3308 Affected file silc/local_command.c.
3310 * Added `data_len' field to SilcIDCache context.
3312 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Update TODO. Todo in commands in the server.
3316 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3319 used by routers as broadcast packet to inform other routers
3320 about the changed user mode.
3322 Implemented the notify handling in the server. Affected file is
3323 silcd/packet_receive.c. Added the function
3324 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3326 * Added new generic Channel Payload and deprecated the New Channel
3327 Payload. The New Channel Payload is now the generic Channel
3330 * Added new argument `mode' to the silc_server_send_new_channel
3331 as it is required in the Channel Payload now.
3333 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3334 and created a new and real SilChannelPayload to represent the
3335 new generic Channel Payload. Implemented the encode/decode
3336 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3338 * Added silc_server_get_client_channel_list to return the list
3339 of channels the client has joined for WHOIS command reply.
3340 Affected file silcd/server.[ch].
3342 * Implemented the channel list sending in the WHOIS command reply
3343 in server and in the client.
3345 Implemented the channel list displaying on the user interface
3346 as well. Affected file silc/client_ops.c.
3348 * Added silc_channel_payload_parse_list to parse list of Channel
3349 Payloads. It returns SilcDList list of SilcChannelPayloads.
3350 Client for example can use this function to parse the list of
3351 channels it receives in the WHOIS command reply. The caller
3352 must free the list by calling silc_channel_payload_list_free.
3353 Affected files lib/silccore/silcchannel.[ch].
3355 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Added one new argument <user mode> to the WHOIS command reply
3358 to return the mode of the user in SILC. Updated the protocol
3361 Implemented it to the server and client.
3363 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Fixed the mode printing on the user interface on joining.
3366 Affected file silc/client_ops.c.
3368 * Implemented the UMODE command and user modes in general to the
3369 client library and to the user interface.
3371 * Implemented the UMODE command to the server.
3373 * The server now sends UNKNOWN_COMMAND error status if client sends
3374 unknown command. Affected file silcd/command.c.
3376 * All server commands now handle the command identifier the right
3377 way when sending the command reply to the client. The client can
3378 use to identify the command replies with the identifier.
3380 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3382 * Added silc_server_get_client_route to resolve the route to
3383 the client indicated by the client ID. Affected file is
3386 * Added silc_server_relay_packet as general function to relay
3387 packet to arbitrary destination. This deprecates functions
3388 like _send_private_message_key, _relay_notify etc. Affected
3389 file is silcd/packet_send.[ch].
3391 Removed silc_server_send_key_agreement,
3392 silc_server_send_private_message_key and
3393 silc_server_packet_relay_notify functions from the file
3394 silcd/packet_send.[ch].
3398 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3399 server. Affected file silcd/packet_receive.[ch].
3401 * Implemented the KILL command to the client. Implemented the
3402 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3403 Affected files lib/silcclient/command[_reply].c and
3404 lib/silcclient/client_notify.c. Implemented the KILL notify
3405 printing in the user inteface.
3407 * Fixed a lot silc_parse_nick memory leaks from the client
3408 library in the file lib/silcclient/command.c.
3410 * Changed the silc_server_send_notify_on_channels's `sender'
3411 argument from SilcSocketConnection to SilcClientEntry to
3412 check the sender as entry and not as connection object and not
3413 to send to the client provided as argument. The affected file
3414 is silcd/packet_send.[ch].
3416 * The notify packets that are destined directly to the client used
3417 to not to be processed by the server. Now changed that and the
3418 server processes all notify packets. After relaying the packet
3419 to the client the notify packet is processed in the server.
3421 * The silc_server_free_client_data now checks whether there is
3422 pending outgoing traffic for the client and purges the data to
3423 the network before removing the client entry.
3425 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3427 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3428 an client is killed from the SILC Network. Updated the protocol
3431 Added new function silc_server_send_notify_killed to the
3432 silcd/packet_send.[ch].
3434 * Added function silc_server_packet_relay_notify to relay notify
3435 packets that are destined directly to a client. In this case
3436 the server does not process the notify packets but merely relays
3437 it to the client. Affected file silcd/packet_send.[ch].
3439 Added also silc_server_packet_process_relay_notify to check
3440 whereto relay the notify. Affected file is
3441 silcd/packet_receive.[ch].
3443 * Implemented the KILL command to the server.
3447 * Added the backup schema desgined last fall to the protocol
3448 specs for everyone to see. The specification is in the
3449 *-spec-xx.txt draft and the packet type definitions for the
3450 backup routers is in *-pp-xx.txt draft. Thusly, added also
3451 new packet type SILC_PACKET_CELL_ROUTERS.
3453 * A big security problem in the implementation discovered. The
3454 signoff of an client did not cause new channel key generation
3455 which it of course should've done. The channel keys must be
3456 always re-generated when client leaves (or signoffs) the channel.
3457 The silc_server_remove_from_channels funtion now handles
3458 the channel key re-generation.
3460 * Added `sender' argument to the silc_server_send_notify_on_channels
3461 to not to send the client provided as argument. Affected file
3462 silcd/packet_send.[ch].
3464 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Implemented OPER and SILCOPER commands into the server and
3469 * Added silc_auth_verify and silc_auth_verify_data to verify
3470 the authentication directly from the authentication payload.
3471 It supports verifying both passphrase and public key based
3472 authentication. Affected file lib/silccore/silcauth.[ch].
3474 * Added `hash' field to the SilcIDListData structure. It is the
3475 hash negotiated in the SKE protocol. Affected file is
3478 * Slight redesigning of the SilcAuthPayload handling routines.
3479 Do not send SilcPKCS but SilcPublicKey as argument.
3481 * Implemented the public key authentication support to the
3482 serverconfig. The public key is loaded from the provided path
3483 and saved as authentication data to void * pointer. Thus,
3484 changed the unsigned char *auth_data to void *auth_data;
3486 * Fixed SHUTDOWN command to send the reply before the server
3487 is shutdown. :) Affected file silcd/command.c.
3489 * Fixed fatal bug in CONNECT command. The hostname was invalid
3490 memory and server crashed. Affected file silcd/command.c.
3492 * Fixed fatal bug in CLOSE command. The server_entry became
3493 invalid but was referenced later in the command. Affected file
3496 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Fixed fatal bug in failure packet handling. Server ignored
3499 the failure and thus crashed when it came.
3503 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3505 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3506 that the command may be executed only once in (about) 2 seconds.
3507 The old SILC_CF_LAG flag is same but allows command bursts up
3508 to five before limiting.
3510 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3511 server code. Various commands now includes the CF_LAG_STRICT
3512 flag to disallow any kind of miss-use of the command.
3514 * Fixed the silc_buffer_unformat to not to allocate any data
3515 if the length of the data is zero. It used to allocate the
3516 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3518 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Changed the format of AdminConnection configuration section
3521 in the server. Added username of the admin to the format.
3522 Affected files silcd/serverconfig.[ch].
3524 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3525 to return admin configuration data by host, username and/or
3528 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Implemented WHOWAS command to the server. Added the functions:
3532 silc_server_command_whowas_parse,
3533 silc_server_command_whowas_send_reply,
3534 silc_server_command_whowas_from_client and
3535 silc_server_command_whowas_from_server
3537 * Added <Client ID> argument to the WHOWAS command reply. Updated
3538 the protocol specs accordingly.
3540 * Implemented WHOWAS command and command_reply to the client
3543 Implemented the WHOWAS printing on the user interface.
3545 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3547 * Added new argument to the WHOWAS command reply, the real name.
3548 It is an optional argument. Updated the protocol specs.
3550 * Added SilcIDCacheDestructor callback that is registered when
3551 the SilcIDCache is allocated. The callback is called when
3552 an cache entry in the ID Cache expires, or is purged from the
3553 cache. Added into lib/silccore/idcache.[ch].
3555 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3556 to destruct the client entries when the cache entry expires.
3557 Other ID Cache's in server and in the client library ignores
3560 * If the ID Cache entry's `expire' field is zero then the entry
3561 never expires. Added boolean `expire' argument to the
3562 silc_idcache_add function in the lib/silccore/idcache.[ch].
3563 If it is TRUE the default expiry value is used.
3565 * Added silc_server_free_client_data_timeout that is registered
3566 when client disconnects. By default for 5 minutes we preserve
3567 the client entry for history - for WHOWAS command.
3569 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3571 * Added support to the server to enforce that commands are not
3572 executed more than once in 2 seconds. If server receives
3573 commands from client more frequently, timeout is registered
3574 to process the commands. Affected file silcd/command.c.
3575 Added new function silc_server_command_process_timeout.
3577 * Changed NICK_NOTIFY handling in client library to check that
3578 if the client's nickname was changed, so there is no need to
3579 resolve anything from the server.
3581 * Removed error printing from the WHOIS and IDENTIFY commands.
3582 If error occurs then it is ignored silently in the client library.
3583 The application, however, may map the received error to
3584 human readable error string. The application currently maps
3585 the NO_SUCH_NICKNAME error to string.
3587 * Made the command status message public to the application. Moved
3588 them from lib/silcclient/command_reply.c to
3589 lib/silcclient/command_reply.h. The application can map the
3590 received command status to the string with the
3591 silc_client_command_status_message function.
3593 * Added check to the server to check that client's ID is same
3594 as the Source ID in the packet the client sent. They must
3597 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Added dist-bzip hook to the Makefile.am to make bzip2
3600 compressed distributions.
3602 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Server now enforces the maximum length for the nickname and
3605 the channel as protocol specification dictates. 128 bytes for
3606 nickname and 256 bytes for channel name.
3608 * Moved the WHOIS printing to the application. The client libary
3609 does not print out the WHOIS information anymore, the application
3610 must do it. Renamed silc_client_command_reply_whois_print to
3611 the silc_client_command_reply_whois_save.
3613 The client's idle time is also sent to the application now, and
3614 the idle is shown on screen.
3616 * Added silc_client_command_reply_identify_save to save the
3617 received IDENTIFY entries.
3619 * Do not check for channel private keys in message sending and
3620 reception if the channel does not have the PRIVKEY mode set.
3621 Affected file lib/silclient/client_channel.c.
3623 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3625 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3626 just surfaced after chaning the JOIN procedure.
3628 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3630 * Added silc_client_get_clients_by_list to get client entries
3631 from Client ID list, that is returned for example by JOIN
3632 and USERS command replies. The application should use this
3633 function for example when JOIN command reply is received to
3634 resolve the clients already on the channel (library does not
3635 do that anymore as USERS command reply is not used in the JOIN
3636 procedure anymore). Affected files lib/silcclient/silcapi.h and
3637 lib/silcclient/idlist.c.
3639 * JOIN command reply and USERS command reply returns now SilcBuffer
3640 pointers instead of unsigned char pointers when returning
3641 the client list and mode list.
3643 * Added <Client ID> argument to the JOIN command reply, mainly
3644 for the server to identify for which client the command was
3645 originally sent. Updated protocol specs accordingly.
3647 * Added SilcDlist private_key pointer to the SilcChannelEntry
3648 in the client to support the channel private keys. Affected
3649 file is lib/silcclient/idlist.h.
3651 * Added SilcChannelPrivateKey argument to the function
3652 silc_client_send_channel_message so that application can choose
3653 to use specific private ke if it wants to. If it is not provided,
3654 the normal channel key is used, unless private keys are set.
3655 In this case the first (key that was added first) is used
3656 as the encryption key.
3658 * Implemented the support for channel private key handling.
3659 Implemented the following functions:
3661 silc_client_add_channel_private_key,
3662 silc_client_del_channel_private_keys,
3663 silc_client_del_channel_private_key,
3664 silc_client_list_channel_private_keys and
3665 silc_client_free_channel_private_keys
3667 Affected file lib/silcclient/client_channel.c.
3669 * Added the support for the private keys in the channel message
3670 sending and encryption and in the message reception and
3671 decryption. Affected funtions are
3672 silc_client_send_channel_message and silc_client_channel_message.
3674 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * Added SKE's key verify callback to the client library's
3677 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3679 * Removed the statement that server (or router) must send USERS
3680 command reply when joining to the channel so that the client
3681 knows who are on the channel. Instead, the client list and
3682 client's mode list is now sent in the JOIN command reply to the
3683 client who joined channel. This is better solution.
3685 * Added function silc_server_get_users_on_channel and function
3686 silc_server_save_users_on_channel to the silcd/server.[ch].
3688 * Removed function silc_server_command_send_users from the
3691 * Do not show topic on the client library anymore. The topic is
3692 sent in the command reply notify to the application and the
3693 application must show the topic now.
3695 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3697 * Added client searching by nickname hash into the IDENTIFY and
3698 WHOIS commands in the server as they were clearly missing from
3699 them. Affected file is silcd/command.c.
3701 * Fixed a bug in private message receiving in the client library.
3702 The remote ID was freed and it wasn't supposed, now it is
3705 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Minor fix to the channel payload; allocate the data area, as it
3708 needs to be of specific length.
3710 * If the key agreement port is zero then the operating
3711 system will define the bound port. Affected files are
3712 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3714 * Added new function silc_channel_payload_decrypt into the file
3715 lib/silccore/silcchannel.[ch].
3717 * Moved the channel message etc, check from silc_packet_decrypt
3718 to applications. The library calls now a generic
3719 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3720 when the packet is either normal or special. This was done to
3721 allow more wide range of checking that was not allowed when
3722 the code was in library. Now applications can do virtually any
3723 checks to the packet and return to the library the decision how
3724 the packet should be processed. Affected files are
3725 lib/silccore/silcpacket.[ch].
3727 Added silc_server_packet_decrypt_check to the server and
3728 silc_client_packet_decrypt_check to the client library.
3730 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3731 to send with specified source and destination information.
3733 * Channel message delivery between routers was broken after the
3734 channel key distribution was fixed earlier. The channel key
3735 was used be to distributed to other routers as well which is not
3736 allowed by the protocol. Now this is fixed and channel keys
3737 really are cell specific and the channel message delivery between
3738 routers comply with the protocol specification.
3740 * Fixed various commands in server to check also the global list
3741 for the channel entry and not just the local list. The affected
3742 file silcd/command.c.
3744 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Added assert()s to buffer formatting and unformatting routines
3747 to assert (if --enable-debug) when error occurs. Affected
3748 file: lib/silcutil/silcbuffmt.c.
3750 * Changed to auto-reconnect to check whether the remote host is
3751 router and register the re-connect timeout if it is. It used
3752 to check that whether we are normal server, but router must do
3753 auto-reconnect with another router as well. Affected file
3756 * Removed the [<key len>] option from CMODE command as the cipher
3757 name decides the key length, nowadays. See the defined ciphers
3758 from the protocol specification.
3760 * Added [<hmac>] option to the CMODE command to define the HMAC
3761 for the channel. Added SILC_CMODE_HMAC channel mode.
3763 * Added [<hmac>] option for the JOIN command so that user can
3764 select which HMAC is used to compute the MACs of the channel
3767 * Added Hmac field to the Channel Message Payload. The integrity
3768 of plaintext channel messages are now protected by computing
3769 MAC of the message and attaching the MAC to the payload. The
3770 MAC is encrypted. Now, it is clear that this causes some
3771 overhead to the size of the packet but rationale for this is that
3772 now the receiver can verify whether the channel message decrypted
3773 correctly and also when private keys are set for the channel the
3774 receiver can decrypt the packet with several keys and check from
3775 the MAC which key decrypted the message correctly.
3777 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3778 lib/silccrypt/silccipher.[ch].
3780 * Added silc_hash_len to return the digest length into the
3781 lib/silcrypt/silchash.[ch].
3783 * Rewrote parts of Silc Channel Payload interface in the
3784 lib/silccore/silcchannel.[ch]. The encode function now also
3785 encrypts the packet and parse function decrypts it.
3787 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Fixed a minor formatting bug in the SKE's key material processing.
3790 It actually might have processed the keys wrong way resulting
3793 * Redefined the mandatory HMAC algorithms and added new algorithms.
3794 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3795 and hmac-md5 truncated to 96 bits. The mandatory is now
3796 hmac-sha1-96. Rest are optional (including the one that used
3797 to be mandatory). Rationale for this is that the truncated HMAC
3798 length is sufficient from security point of view and can actually
3799 make the attack against the HMAC harder. Also, the truncated
3800 HMAC causes less overhead to the packets. See the RFC2104 for
3803 * Added new [hmac] configuration section. The SKE used to use
3804 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3805 is of course wrong. The official names that must be proposed in
3806 the SKE are the ones defined in the protocol specification
3807 (hmac-sha1-96 for example). The user can configure any hmac
3808 using any hash function configured in the [hash] section. At
3809 least, the mandatory must be configured.
3811 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3813 * Added HMAC list to the SKE proposal list. It has now both
3814 hash algorithm list and HMAC list. This makes the protocol
3815 incompatible with previous versions. The SKE now seems to work
3816 the way it is supposed to work, for the first time actually.
3818 * Defined plain Hash algorithms to the protocol specification.
3821 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Implemented support for key agreement packets into the server.
3824 Added functions silc_server_key_agreement and
3825 silc_server_send_key_agreement. Other than these functions,
3826 server has nothing to do with this packet.
3828 * Added support for private message key packets into the server.
3829 Added functions silc_server_private_message_key and
3830 silc_server_send_private_message_key.
3834 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3835 called in the protocol's final callback instead in the END
3836 protocol state. This makes a little more sense and in the same
3837 time in client we can use the same protocol routines for normal
3838 key exchange and to key agreement packet handling as well.
3840 * Added to both client's and server's KE protocol context the
3841 SilcSKEKeyMaterial pointer to save the key material. We will
3842 bring the key material to the protocol's final callback by doing
3843 this. The final callback must free the key material.
3845 * Added SKE's packet_send callback into client's KE protocol
3846 context so that the caller can choose what packet sending function
3847 is used. This way we can use different packet sending when
3848 doing normal SKE when doing key agreement packet handling (in
3849 the key agreement packet handling we do not want to encrypt
3852 * Implemented the responder side of the key agreement routines
3853 in the client. The client can now bind to specified port and
3854 accept incoming key negotiation. The key material is passed
3855 to the application after the protocol is over.
3857 * Implemented the processing of incoming Key Agreement packet
3858 in the client. Added function silc_client_key_agreement to
3861 * Implemented the intiator side of the key agreement routines
3862 in the client. The client can now initiate key agreement with
3863 another remote client. The key material is passed to the
3864 application after the protocol is over.
3866 * Created client_keyagr.c to include all the key agreement
3869 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3870 SILC_TASK_CALLBACK except that it is not static.
3872 * Created client_notify.c and moved the Notify packet handling
3873 from the client.[ch] into that file.
3875 * Created client_prvmsg.c and moved all private message and
3876 private message key routines from the client.[ch] into that file.
3878 * Create client_channel.c and moved all channel message and
3879 channel private key routines from the client.[ch] into that file.
3881 * Changed silc_client_get_client_by_id_resolve to resolve with
3882 WHOIS command instead of IDENTIFY command, in the file
3883 lib/silclient/idlist.c.
3885 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Implemented the SKE's responder side to the Client library.
3889 * When FAILURE is received to the protocol do not trust it
3890 blindly. Register a timeout to wait whether the remote closes
3891 the connection as it should do it, only after that process the
3892 actual failure. This was changed to both client and server.
3894 * Added client_internal.h to include some of the structures
3895 there instead of client.h in lib/silcclient/.
3897 * Added function silc_task_unregister_by_callback to unregister
3898 timeouts by the callback function.
3900 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3902 * Some "Incomplete WHOIS info" errors has been appearing on the
3903 log files. Took away the entry->userinfo check from WHOIS
3904 reply sending. The entry->userinfo is now " " if client did not
3905 provide one. I thought this was fixed earlier but something
3906 is wrong still. Let's see if the error still appears.
3908 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * Fixed a minor bug in the login when the channel key is
3911 re-generated in the server. It used to generate the key in
3912 wrong order and thus caused problems in the channel traffic.
3914 * Fixed a minor bug in channel key distsribution after
3915 KICK command. The key was not sent to the router even though
3918 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3920 * Added silc_ske_process_key_material_data as generic routine
3921 to process any key material as the SILC protocol dictates. The
3922 function is used by the actual SKE library but can be used by
3923 applications as well. This relates to the private message keys
3924 and the channel private keys since they must be processed the
3925 same way the normal SILC session keys. The protocol dictates
3926 this. Affected files: lib/silcske/silcske.[ch].
3928 Added also silc_ske_free_key_material to free the
3929 SilcSKEKeyMaterial structure.
3931 * Defined silc_cipher_set_key function to set the key for
3932 cipher without using the object's method function. The affected
3933 files: lib/silccrypt/silccipher.[ch].
3935 * Implemented silc silc_client_add_private_message_key,
3936 silc_client_add_private_message_key_ske,
3937 silc_client_del_private_message_key,
3938 silc_client_list_private_message_keys and
3939 silc_client_free_private_message_keys functions in the
3942 Added functions silc_client_send_private_message_key to send
3943 the Private Message Key payload and silc_client_private_message_key
3944 to handle incoming Private Message Key payload.
3946 * Added Cipher field to the Private Message Key payload to set
3947 the cipher to be used. If ignored, the default cipher defined
3948 in the SILC protocol (aes-256-cbc) is used.
3950 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * Removed lib/silcclient/ops.h file.
3954 Redefined parts of the SILC Client Library API. Created new
3955 file silcapi.h that deprecates the ops.h file and defines the
3956 published Client Library API. Defined also private message key
3957 API and channel private key API into the file.
3959 This is the file that the application must include from the
3960 SILC Client Library. Other files need not be included by
3961 the application anymore.
3963 * Added new key_agreement client operation callback and also
3964 defined the Key Agreement library API for the application.
3966 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3969 is used by clients to request key negotiation between another
3970 client in the SILC network. If the negotiation is started it
3971 is performed using the SKE protocol. The result of the
3972 negotiation, the secret key material, can be used for example
3973 as private message key.
3975 Implemented the Key Agreement payload into the files
3976 lib/silccore/silauth.[ch].
3978 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Redefined ciphers for the SILC protocol. Added some new ciphers
3981 and defined the key lengths for the algorithms. Changed the
3982 code accordingly. The default key length is now 256 bits.
3984 * Fixed SKE key distribution function silc_ske_process_key_material
3985 when the key length is more than 128 bits. The default key
3986 length in SILC is now 256 bits.
3988 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3989 to indicate unsupported algorithm.
3991 * Renamed rijndael.c to aes.c and all functions as well.
3993 * Fixed a long standing channel key setting bug in client library.
3994 Weird that it has never surfaced before.
3996 * Fixed bug in channel deletion. If the entire channel is removed
3997 then it must also delete the references of the channel entry
3998 from the client's channel list as the client's channel entry and
3999 the channel's client entry share same memory.
4001 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Implemented CONNECT and SHUTDOWN commands in the client.
4005 * Implemented CLOSE command to the client.
4007 * Added the function silc_idlist_find_server_by_name into the
4008 files silcd/idlist.[ch].
4010 Added the function silc_idlist_find_server_by_conn into the
4011 files silcd/idlist.[ch].
4013 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4015 * DIE command was renamed to SHUTDOWN. Updated the both code
4018 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4019 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4021 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4024 * Added function silc_server_create_connection function to create
4025 connection to remote router. My server implementation actually
4026 does not allow router to connect to normal server (it expects
4027 that normal server always initiates the connection to the router)
4028 so the CONNECT command is only good for connecting to another
4031 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4033 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4034 or some other client was kicked from the channel.
4036 Implemented the handling of the notify type to both client
4039 Implemented silc_server_send_notify_kicked to send the KICKED
4040 notify. It is used to send it to the server's primary router.
4042 * Implemented the KICK command into server and client.
4044 * Added `query' argument to the silc_idlist_get_client function
4045 to indicate whether to query the client from server or not if
4048 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4049 to indicate that the client is not channel founder.
4053 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Removed the rng context from SilcPacketContext structure and
4056 changed that the packet routine uses the Global RNG API.
4058 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4060 * Added support for quit message that client can "leave" on the
4061 channel when it quits the SILC. It is ditributed inside the
4062 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4064 Added silc_server_free_client_data that will take the
4065 signoff message as argument.
4067 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4069 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Updated parts of the protocol specification to keep it up
4074 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4076 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4077 payloads in one packet.
4079 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4080 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4081 use now the new List flag.
4083 * Also deprecated the following packet types: REPLACE_ID,
4084 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4086 * Added list support for Notify packet in server.
4088 * Added silc_server_send_notify_channel_change to send the
4089 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4090 the silc_server_send_replace_id.
4092 * Added silc_server_send_notify_nick_change to send the
4093 NICK_CHANGE notify type. Deprecates the function
4094 silc_server_send_replace_id.
4096 * Added silc_server_send_notify_join to send the JOIN notify type.
4097 Deprecates the function silc_server_send_new_channel_user.
4099 * Added silc_server_send_notify_leave to send LEAVE notify type.
4100 Deprecates the function silc_server_send_remove_channel_user.
4102 * Added silc_server_send_notify_cmode and
4103 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4104 types. Deprecates the silc_server_send_set_mode function.
4106 * Added SERVER_SIGNOFF notify type to indicate that server has
4107 quit. This means that all clients on the channel from that
4108 server will drop. This can be also used when netsplit happens.
4110 Deprecated REMOVE_ID packet type since it is not needed anymore
4113 Added silc_server_send_notify_server_signoff to send the
4114 SERVER_SIGNOFF notify type. Deprecates the function
4115 silc_server_send_remove_id.
4117 Added also silc_server_send_notify_signoff to send the
4118 SIGNOFF notify type.
4120 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4121 SILC protocol from this day on. Changed the protocol
4122 specification as well.
4124 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4125 notify type. It is used between routers to notify about
4126 topic changes on a channel.
4128 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4131 * Partly updated the protocol specification to comply with the
4132 changes now made. It is still though a bit outdated.
4134 * The JOIN notify type now takes one extra argument <Channel ID>.
4135 The packet used to be destined to the channel but now the
4136 JOIN type may be sent as list thus it is impossible to
4137 destine it to any specific channel. By adding this argument
4138 it is again possible.
4140 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Added CREDITS file. The CHANGES and CREDITS file will appear
4143 in the distribution as well.
4145 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4147 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4148 types in the server's silcd/packet_receive.c.
4150 * Implemented CMODE and CUMODE to work in router environment.
4152 * Fixed minor encoding and decoding buglet from the
4153 lib/silccore/silcmode.c.
4155 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4158 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4160 * Changed all SilcConfigServer* and silc_config_server* to
4161 SilcServerConfig* and silc_server_config*, respectively.
4164 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Associated the ID (client or server ID) to the Authentication
4167 Payload to avoid any possibility of forging. Updated the
4168 protocol specification and the code accordingly.
4170 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * The RSA key length is now save to the RsaKey context in the
4173 key generation process in lib/silccrypt/rsa.c. The key length
4174 is now used to figure out the maximum size of the block allowed
4175 to be encrypted/signed.
4177 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4178 is equivalent to the silc_mp_mp2bin but does not allocate any
4181 * Changed silc_mp_mp2bin API to take length argument. If it is
4182 non-zero then the buffer is allocated that large. If zero, then
4183 the size is approximated using silc_mp_sizeinbase, which however
4186 * Created Global RNG API which is global RNG that application can
4187 initialize. After initializing, any routine anywhere in the
4188 code (including library) can use RNG without allocating a new
4189 RNG object. This was done to allow this sort of use of the
4190 RNG in code that has no chance to allocate RNG object. All
4191 applications currently allocate this and many routines in the
4192 library use this. Affected file lib/silccrypt/silcrng.[ch].
4194 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4195 it to use the Global RNG API.
4197 * Defined Authentication Payload into protocol specification that
4198 is used during SILC session to authenticate entities. It is
4199 used for example by client to authenticate itself to the server
4200 to obtain server operator privileges.
4202 Implemented this payload into the lib/silccore/silcauth.[ch].
4203 Implemented also routines for public key based authentication
4204 as the new protocol specification dictates.
4206 Moved definitions of different authentication methods from
4207 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4209 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4210 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4211 silc_pkcs_verify_with_hash functions into the file
4212 lib/silccrypt/silcpkcs.[ch].
4214 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * The client entry's userinfo pointer must be always valid.
4217 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4218 will fail since it requires the userinfo. Now, the userinfo
4219 is allocated as "" if actual userinfo does not exist. Actually,
4220 it must exist and it is totally Ok to drop client connections
4221 that does not announce the userinfo. However, we will make
4222 this workaround for now.
4224 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4225 to return the remote port by socket.
4227 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4230 SILC_SERVER_PENDING_EXEC and added an new macro
4231 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4232 data or when error occurs while processing the pending command.
4234 Added new argument `destructor' into silc_server_command_pending
4235 and to the SilcServerCommandPending object. This destructor is
4236 now called after calling the pending callback or if error occurs
4237 immediately. If error occurs the actual pending callback won't
4238 be called at all - only the destructor. The destructor may be
4239 NULL if destructor is not needed.
4241 All this applies for client library code as well. Similar
4242 changes were made there as well for the pending commands.
4244 In the client, the application must now allocate the
4245 SilcClientCommandContext with the silc_client_command_alloc
4248 * Added reference counter to the SilcServerCommandContext. Added
4249 function silc_server_command_alloc and silc_server_command_dup
4252 Same type of functions added to the client library for the same
4255 * Removed the cmd_ident from IDListData away since it is now
4256 global for all connections. It is the command identifier used
4257 in command sending and with pending commands. The affected file
4260 * Added reference counter to the SilcSocketConnection objecet to
4261 indicate the usage count of the object. The object won't be
4262 freed untill the reference counter hits zero. Currently only
4263 server uses this, and client ignores it. The client must be
4264 set to use this too later. The affected files are
4265 lib/silccore/silcsockconn.[ch]. Added also the function
4266 silc_socket_dup to increase the reference counter.
4268 This was mainly added because it is possible that the socket
4269 is removed underneath of pending command or other async
4270 operation. Now it won't be free'd and proper DISCONNECTING
4271 flags, etc. can be set to avoid sending data to connection that
4272 is not valid anymore.
4274 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4275 the connection. After that it sets SILC_SET_DISCONNECTED.
4276 It is, however, possible that the socket data is not still freed.
4277 The silc_server_packet_process now checks that data is not
4278 read or written to connection that is DISCONNECTED. The socket
4279 get's freed when the reference counter hits zero.
4281 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Changed the client operation API: channel_message operation's
4284 `sender' is now the client entry of the sender, not the nickname
4285 and the `channel' is the channel entry, not the channel name.
4287 In the private_message operation the `sender' is now also the
4288 client entry of the sender not the nickname.
4290 Affected file is lib/silcclient/ops.h and all applications
4291 using the client operations.
4293 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Moved the calling of ops->connect() from connect_to_server_final
4296 into receive_new_id functin since that is the point when the
4297 client is actually allowed to send traffic to network. The
4298 affected file is lib/silcclient/client.c.
4300 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4303 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4304 (if needs broadcasting) instead of broadcasting the packets one
4305 by one which would make a burst in the network traffic.
4307 * Added `broadcast' argument to the functions in silcd/server.[ch]
4308 silc_server_create_new_channel[_with_id] to indicate whether
4309 to send New Channel packet to primary router.
4311 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Added new function into the silcd/server.[ch] files:
4314 silc_server_create_new_channel_with_id to create new channel with
4315 already existing Channel ID.
4317 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4318 lib/silccore/silcpacket.h. This packet is used t send list of
4319 Set Mode payloads inside one packet. Server uses this to set
4320 the modes for the channels and clients on those channels, that it
4321 announced to the router when it connected to it. The protocol
4322 specification has been updated accordingly.
4324 * The silc_server_new_channel did not handle the packet coming
4325 from normal server as it normally does not send that. However,
4326 when it announces its channels it does send it. Implemented
4327 the support for that.
4329 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4330 into the file lib/silccore/id.h.
4332 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * Fixed memory leaks in the functions silc_idlist_del_client,
4335 silc_idlist_del_channel and silc_idlist_del_server in the file
4336 silcd/idlist.c. All of those leaked like a sieve.
4338 * Fixed some small memory leaks in the client's function
4339 silc_client_notify_by_server.
4341 * Added functions into silcd/server.c: silc_server_announce_clients,
4342 silc_server_announce_channels and silc_server_announce_server.
4343 These functions are used by normal and router server to announce
4344 to its primary router about clients, channels and servers (when
4345 router) that we own. This is done after we've connected to the
4348 These functions effectively implements the following packet types:
4349 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4350 and SILC_PACKET_NEW_ID_LIST.
4352 * Added new functions into the silcd/packet_receive.[ch]:
4353 silc_server_new_id_list, silc_server_new_channel_list and
4354 silc_server_new_channel_user_list to handle the incoming
4355 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4357 * Added support of changing Channel ID in the function
4358 silc_server_replace_id. If the server that announces a channel
4359 to the router already exists in the router (with same name but
4360 with different Channel ID), router is responsible to send
4361 Replace ID packet to the server and force the server to change
4362 the Channel ID to the one router has.
4364 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4365 client that the Channel ID has been changed by the router. The
4366 normal server sends this to the client. Client must start using
4367 the new Channel ID as the channel's ID.
4369 Implemented handling of this new type into lib/silcclient/client.c
4370 into the function silc_client_notify_by_server.
4372 * Added new function silc_idlist_replace_channel_id into the files
4373 silcd/idlist.[ch] to replace the Channel ID.
4375 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Call silc_server_command_identify_check always when processing
4378 the IDENTIFY command in silcd/command.c
4380 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4383 send keepalive packets. The packet can be sent by clients,
4384 servers and routers.
4386 Added function silc_socket_set_heartbeat into the file
4387 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4388 If not set, the heartbeat is not performed. The actual
4389 heartbeat is implemented in the low level socket connection
4390 library. However, application is responsible of actually
4393 Added silc_server_send_heartbeat to send the actual heartbeat
4394 packet into silcd/packet_send.[ch]. Server now performs
4395 keepalive with all connections.
4397 * Added silc_task_get_first function into lib/silcutil/silctask.c
4398 to return the timeout task with shortest timeout. There was a bug
4399 in task unregistration that caused problems. TODO has been
4400 updated to include that task system must be rewritten.
4402 * The client library will now resolve the client information when
4403 receiving JOIN notify from server for client that we know but
4404 have incomplete information.
4406 * Rewrote parts of silc_server_remove_from_channels and
4407 silc_server_remove_from_one_channel as they did not remove the
4408 channel in some circumstances even though they should've.
4410 * Encryption problem encountered in server:
4412 The LEAVE command used to send the Channel Key packet to the
4413 router immediately after generating it. However, the code
4414 had earlier sent Remove Channel user packet but not immediately,
4415 ie. it was put to queue. The order of packets in the router
4416 was that Channel Key packet was first and Remove Channel User
4417 packet was second, even though they were encrypted in the
4418 reverse order. For this reason, MAC check failed. Now, this
4419 is fixed by not sending the Channel Key packet immediately but
4420 putting it to queue. However, this is more fundamental problem:
4421 packets that are in queue should actually not be encrypted
4422 because packets that are sent immediately gets encrypted
4423 actually with wrong IV (and thus MAC check fails). So, packets
4424 that are in queue should be encrypted when they are sent to
4425 the wire and not when they put to the queue.
4427 However, the problem is that the current system has not been
4428 designed to work that way. Instead, the packet is encrypted
4429 as soon as possible and left to the queue. The queue is then
4430 just purged into wire. There won't be any fixes for this
4431 any time soon. So, the current semantic for packet sending
4434 o If you send packet to remote host and do not force the send
4435 (the packet will be in queue) then all subsequent packets to the
4436 same remote host must also be put to the queue. Only after the
4437 queue has been purged is it safe again to force the packet
4440 o If you send all packets immediately then it safe to send
4441 any of subsequent packets through the queue, however, after
4442 the first packet is put to queue then any subsequent packets
4443 must also be put to the queue.
4445 Follow these rules and everything works fine.
4447 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added new function silc_server_remove_clients_by_server to
4450 remove all client entries from ID list when the server connection
4451 is lost. In this case it is also important to invalidate all
4452 client entires as they hold the invalid server entry. This
4453 fixes fatal bug when server has lost connection and will reconnect
4456 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Made some sanity checks to silc_server_daemonise like to check
4459 whether the requested user and group actually exists.
4461 * Added sanity check to SKE's silc_ske_responder_finish to check
4462 that the public and private key actually is valid.
4464 * Invalidate the client's nickname when receiving Replace ID
4465 packet and the Client ID is being replaced. This means that the
4466 server will query the nickname if someone needs it (client)
4469 * Sort the ID Cache in client library when the ID Cache data
4470 has changed (needs sorting).
4472 * Do not allow for SILC client to create several connections to
4473 several servers. The client does not support windows right now
4474 and generating multiple connections causes weird behaviour.
4476 Irssi-silc client does support windows and can handle several
4477 connections without problems, see: www.irssi.org and SILC plugin.
4479 * Fixed some places where client was added to the IDList. The
4480 rule of thumb is following (in order to get everything right):
4481 If the client is directly connected local client then the
4482 `connection' argument must be set and `router' argument must be
4483 NULL to silc_idlist_add_client function. If the client is not
4484 directly connected client then the `router' argument must
4485 bet set and the `connection' argument must be NULL to the
4486 silc_idlist_add_client function.
4488 * The funtion silc_server_packet_send_local_channel actually did
4489 not check whether the client was locally connected or not. It
4490 does that now. Fixed a bug related to LEAVE command.
4492 * Fixed Remove Channel User payload parsing bug in server's
4493 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4495 * The server's silc_server_save_channel_key now checks also the
4496 global ID list for the channel as it might not be in the local
4497 list. Fixed a bug related to LEAVE command.
4499 * Is this the end of the [<unknown>] buglet that has been lurking
4500 around for a long time? A little for loop fix in server's
4501 silc_server_command_whois_parse that is used by both IDENTIFY
4502 and WHOIS command. At least, this was a clear bug and a cause
4503 of one type of [<unknown>] buglet.
4505 * WHOIS and IDENTIFY commands call the function
4506 silc_server_command_[whois/identify]_check function even if
4507 we are not router server.
4509 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Added --with-gmp configuration option. If set the GMP
4512 is always compiled in the SILC source tree. If not set then
4513 it is checked whether the system has the GMP3 installed. If
4514 it has then the GMP won't be compiled (the system's headers
4515 and library is used), if it doesn't have it then the GMP is
4516 compiled in the SILC source tree.
4518 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Changed RSA private exponent generation to what PKCS #1
4521 suggests. We try to find the smallest possible d by doing
4522 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4523 not security fix but optimization.
4525 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added new config entry [Identity] to fork the server and run
4528 it as specific user and group. A patch from Bostik.
4530 * Imported Dotconf configuration library into lib/dotconf.
4531 This will be used to create the SILC configuration files later.
4532 It will appear in the distsribution after this commit.
4534 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * A big code auditing weekend happening. Auditing code for
4537 obvious mistakes, bugs and errors. Also, removing any code
4540 Removed files for being obsolete:
4542 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4543 inline in the file lib/silcutil/silcbuffer.h)
4545 o lib/silcutil/silcbufutil.c (the header has inline versions)
4547 Changed code to fix possible error conditions:
4549 o The buffer formatting routines now check that the destination
4550 buffer really has enough space to add the data. This applies for
4551 both buffer formatting and unformatting
4552 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4553 unformatting was changed to accomodate following rules:
4554 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4555 sent to the function while XXX_*STRING will not allocate or copy
4556 the data into the buffer. Instead it sets the pointer from the
4557 buffer into the pointer sent as argument (XXX_*STRING used to
4558 require that the pointer must be allocated already). This change
4559 makes this whole thing a bit more consistent and more optimized
4560 (note that the data returned in the unformatting with XXX_*STRING
4561 must not be freed now). The routines return now -1 on error.
4563 o Tried to find all code that use buffer_format and buffer_unformat
4564 and added return value checking to prevent formatting and
4565 especially unformatting errors and possible subsequent fatal
4568 o Changed ske->x and ske->KEY to mallocated pointers in
4569 lib/silcske/silcske.h. Fixed possible data and memory leak.
4571 o Added return value checking to all *_parse* functions. Fixed
4572 many memory leaks as well.
4574 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4575 so that buffer overflows would not happen. All code now also
4576 checks the return value as it can fail.
4578 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Added reconnection support to server if the normal server looses
4581 its connection to the router (for example if router is rebooted).
4582 The server performs normal reconnection strategy implemented
4583 to the server. Affected file silcd/server.c.
4585 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4587 * Added new packet type SILC_PACKET_SET_MODE that is used to
4588 distribute the information about changed modes (for clients,
4589 channels and clients channel modes) to all routers in the
4590 network. Updated the protocol specification accordingly.
4592 Added functions into silcd/packet_send.c and
4593 silcd/packet_receive.c: silc_server_send_set_mode,
4594 silc_server_set_mode.
4596 Added new files silcmode.[ch] into lib/silccore that implements
4597 the encoding and decoding of Set Mode Payload. Added new type
4598 SilcSetModePayload. Moved the definitions of different modes
4599 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4601 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Oops, a little mistake in server's connection authentication
4604 protocol. The protocol is not ended with FAILURE but with
4605 SUCCESS if the authentication is Ok. :) Affected file is
4608 * Implemented NICK_CHANGE notify handling in server in the file
4609 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4610 the local clients on the channel. After the changing nickname
4611 in router environment snhould work and the [<unknown>] nickname
4612 should appear no more.
4614 The silc_server_replace_id function that receives the Replace ID
4615 payload now sends the NICK_CHANGE notify type also in the file
4616 silcd/packet_receive.c
4618 * Changed WHOIS and IDENTIFY command to support the maximum amount
4619 of arguments defined in protocol specs (3328 arguments). This
4620 fixed a bug that caused problems when there were more than three
4623 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Added extra parameter, command identifier, to the
4626 silc_client_send_command so that explicit command identifier
4629 Changed that ID list routines uses specific command identifier
4630 when sending WHOIS/IDENTIFY requests to the server so that they
4631 can be identified when the reply comes back.
4633 Affected files lib/silcclient/command.[ch],
4634 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4636 * Added `sender' argument to silc_server_packet_send_to_channel
4637 to indicaet the sender who originally sent the packet to us
4638 that we are now re-sending. Ignored if NULL. Affected file
4639 silcd/packet_send.[ch].
4641 * Added some server statistics support in silcd/server_internal.h
4642 SilcServerStatistics structure and around the server code. Also
4643 send some nice statistics information when client is connecting
4646 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4648 * Fixed channel ID decoding in server's JOIN command reply in
4649 silcd/command_reply.c
4651 * Fixed braodcasting of replace ID payload to not to send it if
4652 we are standalone server in silcd/packet_receive.c.
4654 * Fixed all channel message sending routines to not to send
4655 packets to clients that has router set, since they are routed
4656 separately in the same function earlier. Affects file
4657 silcd/packet_send.c and all channel packet sending functions.
4659 * In USERS reply, res_argv[i] are not allocated, the table
4660 is allocated. Thus changed that free the table, not its
4663 * In server's whois_check and identify_check if the client is
4664 locally connected do not send any WHOIS commands - they are not
4667 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4669 * Fixed some minor bugs in client when sending WHOIS command. The
4670 arguments was in wrong order.
4672 * Removed statis function add_to_channel from server in
4673 silcd/command.c that was previously used with the joining but
4676 * Tested USERS command in router environment successfully with two
4677 routers, two servers and two clients.
4679 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Reorganized the USERS command and command reply in client library
4682 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4683 When the command is given by user we register a pending command
4684 callback that will reprocess the command after the reply has been
4685 received from the server. When reprocessing the packet we then
4686 display the information. Thus, the USERS information is displayed
4687 now in the command callback instead of in the command reply
4688 callback. The processing of the command is same as previously
4689 when server has sent the command reply in the JOINing process.
4691 * Added to USERS command in silcd/command_reply.c to join the client,
4692 we didn't use to know about, to the channel after we've created
4693 a client entry for it. Also, for clienet we did know already still
4694 check whether it is on the channel or not and add it if not.
4696 * Removed silc_server_command_join_notify as the function and its
4699 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Changed the client's pending command handling to the same as the
4702 server's pending command handling. It is also now possible to
4703 execute command reply functions from other command reply
4704 function as the function callbacks for commands and command
4705 replies are one and same. The pending commands are not static
4706 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4707 in client connection context. Thus, pending commands are server
4708 connection specific as it is convenient.
4710 Changed the function silc_client_command_pending and
4711 silc_client_command_pending_del and added new function
4712 silc_client_command_pending_check. Removed the
4713 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4716 * Added cmd_ident, current command identifier, to the client
4717 connection context in lib/silcclient/client.h to keep track on
4718 command identifiers used in command sending. Client's command reply
4719 function handling now supports the mandatory command identifiers.
4721 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4722 funtions in client to fully support pending command callbacks.
4724 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4725 as one of the arguments to the application in the command reply
4728 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4729 before first releasing SILC but came back. Now it is removed again
4730 and should come back nomore. The FORWARDED flag was used only
4731 by the JOINing procedure by forwarding the command packet to router.
4732 Now, the JOINing procedure has been changed to more generic (due
4733 to various router environment issues) and FORWARDED is not needed
4734 anymore for anything. The protocol specification is yet to be
4737 Now, removed silc_server_packet_forward from server and the flag
4738 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4740 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Renamed NAMES command to USERS command. The NAMES was named that
4743 due to historical reasons. Now it is renamed. Also, rewrote
4744 parts of the USERS command. The nickname list is not sent anymore
4745 by the server. Only Client ID and mode lists are sent in the USERS
4746 command. Changed this also to the protocol specification.
4748 The client now resolves the names and stuff after it receives
4749 the USERS list from the server when joining to the channel.
4751 * WHOIS and IDENTIFY commands has been changed to support multiple
4752 Client ID's per command. One can now search for multiple users
4753 in the network by sending only one WHOIS or IDENTIFY command.
4754 Changed the code and the protocol specifications.
4756 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4757 uses silc_server_command_whois_parse to parse the request. */
4759 * If normal server, do not parse the WHOIS and IDENTIFY requests
4760 before sending it to the router. Saves some time.
4762 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Fixed JOIN command on client library. Wrong number of arguments
4765 used to crash the client.
4767 * Added silc_server_channel_has_global function to check whether
4768 channel has global users or not.
4770 * Added silc_server_channel_has_local function to check whether channel
4771 has locally connected clients on the channel.
4773 * The silc_server_remove_from_one_channel now checks whether the
4774 channel has global users or not after given client was removed from
4775 the channel. It also checks whether the channel has local clients
4776 on the channel anymore. If it does not have then the channel entry
4777 is removed as it is not needed anymore.
4779 * The silc_server_notify now checks on JOIN notify whether the joining
4780 client is one of locally connected or global. If it is global then
4781 the channel has now global users on the channel and that is marked
4782 to the channel entry. Also, it now saves the global client to
4783 global list who is joining and JOINs it to the channel. This is
4784 for normal server, that is.
4786 Changed silc_server_send_notify_on_channel,
4787 silc_server_packet_relay_to_channel and
4788 silc_server_packet_send_to_channel check if we are normal server
4789 and client has router set (ie. global client) do not send the
4790 message to that client, as it is already routed to our router.
4792 * Implemented LEAVE notify type handling in silc_server_notify
4795 * Tested LEAVE command in router environment successfully. Tested
4796 with two routers, two servers and two clients.
4800 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4802 * Implemented SIGNOFF notify type handling in silc_server_notify
4805 * silc_server_remove_id now removes the client entry from all channels
4806 it has joined and thusly sends SIGNOFF notify type.
4808 * Rewrote the NAMES list generation in server by removing two excess
4809 loops. The lists are created now inside one loop.
4811 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * silc_server_remove_channel_user checks now also global list
4814 for channel and client.
4816 * silc_server_new_channel_user checks now both local and global
4817 list for channel and client. Fixed a bug in client id decoding.
4818 Used to decode wrong buffer.
4820 * silc_server_channel_message checks now both local and global
4821 list for channel entry.
4823 * Tested channel joining (hence JOIN) in router environment
4824 successfully. Tested with two routers, two servers and two
4827 * Tested channel message sending in router environment successfully.
4829 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4831 * Added silc_server_save_channel_key into server.[ch] to save the
4832 received channel key in Channel Key payload processing. It is
4833 also used in JOIN command reply handling.
4835 Equivalent function silc_client_save_channel_key added into
4836 client.[ch] into client library.
4838 * Changed JOIN command reply to send information whether the channel
4839 was created or not (is existing already) and the channel key
4840 payload. Changed protocol specs accordingly.
4842 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4843 the request was sent by ID and not by nickname. Crashed on
4846 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4848 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4849 now correctly save the received data.
4851 * silc_server_free_sock_user_data now notifies routers in the
4852 network about entities leaving the network.
4854 At the same time implemented functions silc_server_remove_id
4855 and silc_server_send_remove_id to receive and send REMOVE_ID
4856 packets. The packet is used to notify routers in the network
4857 about leaving entities. The ID removed will become invalid in
4860 * Added function silc_idlist_del_server into server. Removes and
4861 free's server entry from ID list.
4863 * silc_server_private_message function now checks, if we are router,
4864 that the destination ID really is valid ID, naturally.
4866 * In router when NEW_ID packet is received (for new client) the
4867 hash of the Client ID is saved in the ID Cache but the
4868 client->nickname is set to NULL, instead of putting the hash
4871 IDENTIFY command now also checks that client->nickname must be
4872 valid. If it is not if will request the data from the server who
4873 owns the client. Added new function
4874 silc_server_command_identify_check.
4876 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4877 to set the command to already allocated Command Payload.
4879 * Tested private message sending in router environment with two
4880 routers, two servers and two clients. Fixed minor bugs and now
4883 * Fixed segfault from client's NAMES command. Used to crash if
4886 * Forwarded packets must not be routed even if it is not destined
4887 to the receiver. Changed server code comply with this.
4889 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Added `require_reverse_mapping' boolean value to ServerParams
4892 structure. If TRUE (not default) the server will require that
4893 the connecting host has fully qualified domain name.
4895 If the reverse mapping is not required and hostname could not be
4896 found the IP address is used as hostname.
4898 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * Implemented version string checking to both client and server.
4901 The check is incomplete currently due to the abnormal version
4902 strings used in development version of SILC.
4904 * Changed all command functions in server to use the new
4907 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Changed char *data to unsigned char *data in ID Cache system to
4910 support binary data as ID Cache data. Changed code to support
4911 binary data in lib/silccore/idcache.c.
4913 * Renamed silc_server_packet_relay_command_reply to
4914 silc_server_command_reply as it is normal packet receiving
4915 function. Rewrote the function to accept command replys for
4916 servers and not only for clients.
4918 * Mark remote router always as registered server if we are connecting
4919 to it. Otherwise, commands sent by the router to us are ignored.
4921 * All ID List find routines now returns the ID Cache Entry pointer
4922 as well if requested.
4924 * WHOIS command works now in router environment, tested with two
4925 routers, two servers and two clients.
4927 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4928 in router environment (as it is almost equivalent to WHOIS) but
4929 hasn't been tested thoroughly. Added new functions:
4931 silc_server_command_identify_parse
4932 silc_server_command_identify_send_reply
4933 silc_server_command_identify_from_client
4934 silc_server_command_identify_from_server
4936 * Disabled route cache adding because adding two different ID's with
4937 same IP replaces the old cache entry thus giving wrong route.
4938 The entry->router->connection is always the fastest route anyway
4939 so route cache may not be needed. Of course, new routes maybe
4940 established after receiving the ID when the entry->router->connection
4941 might not be anymore the most optimal.
4943 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Add route cache for received ID for fast routing.
4947 * Added silc_server_packet_route to route received packet on router
4948 that is not destined to us.
4950 * Renamed silc_server_get_route to silc_server_route_get.
4952 * Added id_string and id_string_len fields into SilcServer to
4953 include encoded ServerID for fast comparing without excess
4954 encoding of the ID's.
4956 * Cleaned up WHOIS command on server side. Added following static
4959 silc_server_command_whois_parse
4960 silc_server_command_whois_check
4961 silc_server_command_whois_send_reply
4962 silc_server_command_whois_from_client
4963 silc_server_command_whois_from_server
4965 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4966 arguments in command replies. All command functions should be
4967 updated to use this macro.
4969 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Minor typo fixes on command reply handling on server.
4973 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * Added silc_server_command_add_to_channel internal routine to add
4976 the client to the channel after router has created the channel and
4977 sent command reply to the server.
4979 * Added generic silc_server_send_command to send any command from
4982 * Use static buffer with ID rendering instead of duplicating data.
4984 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Fixed a channel user mode bug when joining to a channel server gave
4987 everybody channel founder rights, oops.
4989 * We mark ourselves as the router of the incoming server connection
4990 if we are router ourselves. This way we can check in some packet
4991 sending functions whether it is locally connected server. For
4992 incoming router connections we put NULL.
4994 * For router sending packets locally means now always sending the
4995 packet cell wide; to local clients and local servers. For normal
4996 server sending packet locally means sending it to only local
4999 * Fixed the JOIN command to really work in router environment. If the
5000 channel is created it is always created by the router. Router is
5001 also responsible of making the initial joining to the channel,
5002 sending JOIN notify to the sending server and distributing
5003 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5004 does not exist server doesn't do anything else but forward the
5005 command to the router which performs everything.
5007 * Added silc_server_send_channel_key function to send the Channel Key
5010 * Added silc_server_create_channel_key to create new channel key. The
5011 channel key is now re-generated everytime someone joins or leaves
5012 a channel, as protocol dictates. Note: channel->key_len is the
5015 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5018 packet_receive.[ch] to separate packet sending and receiving
5019 routines. The server.[ch] now includes everything else including
5020 actual packet processing (writing and reading data) and other
5023 Renamed silc_server_private_message_send_internal to
5024 silc_server_send_private_message. The routine is still though
5025 used only to relay private messages as server does not send
5026 private messages itself.
5028 Renamed silc_server_new_channel to silc_server_create_new_channel
5029 and added new function sicl_server_new_channel that handles the
5030 incoming New Channel packet. Added also new sending function
5031 silc_server_send_new_channel to send New Channel Payload.
5033 * Added new function silc_server_notify to process incoming notify
5034 packet to the server/router. Server may then relay the notify
5035 to clients if needed.
5037 * Added new function silc_server_new_channel_user to process incoming
5038 New Channel User packet. Router will redistribute the packet and
5039 send JOIN notify to its local clients and locally connected servers
5040 if needed. Normal server will send JOIN notify to its local client
5041 on same channel when received this packet. Added also corresponding
5042 sending function silc_server_send_new_channel_user to sent the
5045 * Added boolean route argument to send_notif_to_channel and
5046 packet_send_to_channel functions to attempt to route the packet
5047 if it is TRUE and send only locally if it is FALSE.
5049 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * silc_server_replace_id now broadcasts the received replace ID
5052 packet if it is not broadcast packet already. The router must
5053 broadcast to inform other routers about changed ID.
5055 * Added backpointer to server's router into SilcServer context in
5056 silcd/server_internal.h.
5058 * Fixed silc_server_packet_broadcast to send correct broadcast
5061 * The channel key is now distributed to the local client as soon
5062 as it is received from the router (in router environment) so that
5063 no other packet may be sent for the channel until client has
5066 * silc_server_remove_channel_user now broadcasts the received
5067 Remove Channel User packet if it is not broadcast packet already.
5068 The router must broadcast to inform other routers about removed
5071 * Added users field into SilcPacketContext that is a reference count
5072 of the context. One can increase the reference count by calling
5073 silc_packet_context_dup which is now changed to just increase the
5074 reference count instead of duplicating the data. The reference
5075 count is decresed by calling silc_packet_context_free that will
5076 free the data after the reference count hits zero.
5078 For now on the packet context and everything allocated into it
5079 (including the raw packet from network) must be freed by calling
5080 the new silc_packet_context_free function. Added also new function
5081 silc_packet_context_alloc that must be used now to allocate the
5082 context. This also means that if a routine is asynchronous from
5083 silc_[client/server]_packet_parse_type the packet context must
5084 be duplicated by calling silc_packet_context_dup. Otherwise it
5085 gets free'd after silc_[client/server]_packet_parse_type returns.
5086 Also, one must remember that if packet is duplicated then its
5087 reference count must be decresed by calling the free function as
5088 many times as it was duplicated.
5090 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5091 from both client and server.
5093 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Made joining to a channel working in router environment.
5097 * Cleaned up JOIN command on server side and create function
5098 silc_server_command_join_channel internal routine to make the
5101 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Changed silc_command_pending list to SilcDList. Also, added
5104 `ident' field to SilcServerCommandPending structure to identify
5105 the reply and to call correct callback.
5107 Added silc_server_command_pending_check function to replace the
5108 corresnponding macro. The silc_command_pending list is not
5111 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5112 to set identifier to previously allocated Command Payload. It
5113 is used to set identifier for command when resending Command
5116 * Added silc_command_payload_encode_payload to encode Command
5117 Payload buffer from SilcCommandPayload structure.
5119 * Added silc_argument_payload_encode_payload to encode Argument
5120 payload buffer from SilcArgumentPayload structure.
5122 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Changed WHOIS command to support router connection on server side.
5125 The whois request is always sent to router unless the server is
5126 standalone server. After server has received the reply from the
5127 router will it send the reply to the client.
5129 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5130 broadcast received broadcast packet. The function is used only
5131 by router. The broadcast packet is always sent to the router's
5134 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5135 render given ID to printable string, for log files for example.
5137 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5139 * Made basic router to router connections working. At least they
5140 can now connect to each other but nothing really works the way
5141 they are supposed - yet.
5143 * Added new initiator token to RouterConnection configuration
5144 file in silcd/serverconfig.[ch]. It is used to tell whether we
5145 are the initiator to the remote router or whether we'll expect
5146 the other end to connect.
5148 * Moved registering of listener task to silc_server_init, hence
5149 the server starts listenning as soon as it is run, even if it
5150 does not have connections to other routers. Let's see how well
5153 * Changed default connection retry timeouts for more suitable in
5156 * Removed cipher and such arguments from silc_idlist_add_client
5157 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5158 Added new function silc_idlist_add_data to add the keys and stuff
5161 * Added SilcIDListData structure and added it to SilcClientEntry
5162 and SilcServerEntry as their first field in the structure. This
5163 way we can explicitly cast the ID entries to the SilcIDListData
5164 structure and get common data for the entries. In past, we had
5165 to first check what type of connection it is and then cast it to
5166 correct ID entry type. Now, we can directly cast the opaque
5167 pointer to the SilcIDListData (no matter what ID entry it actually
5168 is) and get the data needed.
5170 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5173 in some circumstances even if threre were timeout tasks, though not
5174 IO tasks, but tasks anyway. Now fixed.
5176 * Defined SilcServerConnection structure to hold connection specific
5177 stuff about directly connected servers and routers. The definition
5178 is currently in silcd/server_internal.h. I thought about having
5179 a bit more important role fro this struct but for now it is used
5180 only when connecting to other server (or router actually).
5182 * Added connecting retry support in server when connecting to
5183 router(s). The retry feature implement exponential backoff
5184 algorithm. Also, added SilcServerParams structure to hold default
5185 parameters for server. For now, it include these retry settings
5186 and are hard coded. After server is moded to be as Silc Server
5187 Library this structure will be more important.
5189 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Changed client librarys channel->clients table to SilcList and
5192 changed code accordingly.
5194 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Changed client's channel table to SilcList and changed code
5197 accordingly. Also changed SilcChannelClientEntry to include back-
5198 pointer to the channel so that client entry can use that structure
5199 as list as well and we have fast cross-reference to the channel.
5200 This change dramatically decreased the complexity of channel
5201 handling with client entry and vice versa (removed one extra
5202 loop when searching for channel entry from many functions).
5204 * Changed server->sim from table to SilcDList and changed code
5207 * NAMES command can now be used from user interface. It will show
5208 the user list on the channel, neatly.
5210 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5211 Code now saves realname of the user if it becomes available.
5213 * Renamed configure.in to configure.in.pre and made ./prepare
5214 script to automatically add correct version string to
5215 configure.in which it creates from configure.in.pre.
5217 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5219 * NAMES command reply now shows users mode with the nickname when
5222 * Moved silc_client_ch[u]mode[_char] functions from
5223 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5224 place sucks, they are utility functions and should be in some
5227 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5229 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5232 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Added TRQ (efficient deque and list library) into lib/trq. This is
5237 a very good list library that is currently used in the SILC. Defined
5238 SilcList API over the library because I didn't like the API very
5239 much. See lib/trq/silclist.h for the API and examples of how to
5240 use the API. Fixed various places in the code to use the new
5241 SilcList API. The SilcList is meant for lists that has a structure
5242 already defined as a list. It is not suitable to add just some
5243 context to the list (in TRQ, the context is the list actually).
5245 So, I defined SilcDList that can be used for the purpose where
5246 predefined list structure does not exit. This can be used as
5247 such list. Now some context just can be added to the SilcDList.
5248 Currently this list is not used in the SILC just yet, though there
5249 are a lot places where this can replace dynamically allocated
5250 tables and I will fix these places, later, to use SilcDList.
5251 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5252 and use TRQ internally).
5254 Also fixed some annoying warning messages that the original TRQ
5255 code generated. Also minor changes to TRQ's Makefile.in.
5257 * Added support for querying by Client ID to both WHOIS and
5258 IDENTIFY commands into server, as required by the protocol.
5260 * Removed method function pointers from SilcBuffer structure. They
5261 weren't used to anything and just increased the context size for
5262 no good reason. This change also made silc_buffer_alloc and
5263 silc_buffer_free functions inline functions.
5265 * Disabled command flooding detection support until it's fixed so
5266 that it accepts commands in but does not execute them more than once
5269 * Added silc_net_localhost(), to return local hostname, into
5270 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5271 that must be initialized before calling silc_client_init.
5273 * Added new function: silc_server_send_notify_on_channels to send
5274 notify messages to all channels client has joined. It is assured
5275 that the message is sent only once per client.
5277 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5278 lib/silcutil/silcutil.[ch] as silc_format function. The new
5279 function is generic and is used by server as well, not only by
5280 the logging routines.
5282 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5283 the provided version string was not acceptable. Added new function:
5284 silc_ske_check_version into lib/silcske/silcske.h. The function
5285 must be implemented by the application (client or server) and it
5286 does not reside in the SKE library. The function checks the version
5287 string remote end sent.
5289 * Added back pointers (to opaque context and to SilcSocketConnection)
5290 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5292 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5293 duplicate packet context structure.
5295 * Changed `notify' client operation to send same arguments as client
5296 receives from server except for ID's. ID's are mapped to correct
5297 ID entry and that is returned. Also, if channel entry is not sent
5298 by server but the notify is for channel the channel entry is sent
5299 to application (otherwise application doesn't know that it is for
5300 channel (library gets it from packet's Destination ID)).
5302 * Added silc_client_remove_from_channels into client library to
5303 remove a client from all channels it has joined to. Used when
5304 received SIGNOFF notify from server. Added also new function
5305 silc_client_replace_from_channels to replace old ID entry with
5306 new ID entry on all channels. Used when received NICK_CHANGE
5309 * Fixed ID Cache list handling in silc_idlist_get_client in
5310 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5311 to get (or query) client by ID.
5313 * Updated TODO list.
5315 * Added connection authentication status message defined by the
5316 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5317 support for these into the code in client and server side.
5319 * Added generic function silc_client_send_command to send any command
5320 with variable argument list. Application should use this function
5321 to send commands if the command functions provided by the library
5322 does not suite for the application's user interface needs.
5324 * Added new `failure' client operation. Application is notified about
5325 received failure packet if client is executing a protocol. In this
5326 case the protocol's execution has failed.
5328 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5329 is required by the protocol.
5331 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5332 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5335 * Added status flag to SilcSKE object to indicate realtime status
5336 of the SKE protocol.
5338 * Application receives now exactly same command reply arguments as
5339 the library receives from server. However, if ID is received the
5340 corresponding ID entry is returned to the application (eg. Client
5341 ID is mapped to correct SilcClientEntry entry and that is returned).
5342 Changed command_reply client operation due to this change.
5344 * Changed all ID's in commands and in command replys as ID Payloads.
5345 Change affected both client and server side codes.
5347 All ID's sent in SILC network (with execption of ID's in SILC
5348 Packet header) are sent in ID Payload to support variable length
5351 * Server now notifies nick changes and notifies all clients on
5352 the channels about the new nickname (about the new Client ID,
5355 * Implemented CMODE command to change channel modes. Supports all
5356 channel modes defined by the protocol specs except ban and invite
5357 lists. (Also, private channel key mode is supported but support for
5358 setting private channel key in client is missing, thus, this mode
5359 has no effect on client side (except that server requires that the
5360 client uses private channel key and normal channel traffic does not
5363 Also, invite mode works per se, but INVITE command does not work
5364 yet correctly, so you can set channel as invite only channel but
5365 inviting clients to the channel does not work (it is yet to be
5366 thought what's the best way to do it).
5368 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5369 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5370 Implemented CUMODE command to change user's mode on the channel.
5371 Supports all modes defined by the protocol specs.
5373 * Added NAMES command reply to return users modes on the channel.
5375 * Removed unnecessary and slow ciphers from lib/silccrypt.
5377 * Set SO_KEEPALIVE option to connection sockets by default.
5379 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5381 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5382 redefined the Notify Payload into protocol specs.
5384 * Added silc_id_payload_parse_id to get ID directly from raw
5387 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5389 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5390 accept searching by Client ID as well.
5392 * Added support for LEAVE and SIGNOFF notify types in client library.
5394 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5395 to parse ID Payload from raw data.
5397 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5399 * Added flags parameter into silc_ske_assemble_security_properties
5400 function in lib/silcske/silcske.[ch].
5402 * Changed notify client operation to fit better for notify messages
5403 sent by server. The notify payload received from server is now
5404 passed to the application (after parsing it to SilcNotifyPayload).
5405 It is application's responsibility to retrieve the arguments
5406 from the payload and show the message the way it wants. The message
5407 sent by server is implementation specific.
5409 * Changed public keys to comply with the protocol specification.
5410 Old public keys are not supported anymore and are not compatible.
5412 * Removed nickname from Channel Payload as the latest draft removed
5413 it. The client must resolve the nickname from the NAMES command
5414 reply received when it joined the channel.
5416 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5418 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Fixed some errors in protocol specification drafts.
5422 * Created lib/silccore/silcnotify.c to implement Notify Payload
5423 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5424 generic payloads described by protocol specifications. The file
5425 includes implementations for ID Payload and Argument Payload.
5427 * Changed Command Payload implementation to use the new Argument
5428 Payload. Changed command_xxxx_payload to command_payload_xxxx
5429 to comply with SILC coding conventions.
5431 * Added suppport for Argument Payload handling in Notify Payload
5432 implementation as protocol requires it. Added the new support
5433 into server and client lib as well.
5435 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Added support for multiple nicknames on same channel. [n] is
5438 added locally to the nickname if there are more than one same
5439 nicknames on the channel.
5441 * Server now sends all nicknames that matched WHOIS request.
5442 Client also shows the list received from server.
5444 * Added TOPIC command to client side. User can now set and show
5445 current topic on channel.
5447 * Added MOTD command to client and server. Also, server sends the
5448 motd when client connects to the server.
5450 * Changed version strings to comply ISO 8601.
5452 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Fixed protocol error handling in client library. It should now
5455 cope even if the SKE fails for some reason.
5457 * Made new protocol specification drafts for submitting to IETF.
5459 * Implemented TOPIC command to server in silcd/command.c.
5461 * Added two new notify types into lib/silccore/silcnotify.h:
5462 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5463 notify nickname change and topic setting/change on a channel.
5465 * API change of command_reply operation in client library. The
5466 application gets now the status type received from server as well.
5468 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5472 * Cras fixed and optimized the packet handling even further and
5473 it should work now. Minor change to the prototype of function
5474 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5476 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Added new function into lib/silcutil/silcschedule.[ch]:
5479 silc_schedule_with_fd to select() a specified fd. The function
5480 returns after timeout expires or data arrives or goes. The
5481 function is used by packet routines to wait that all data is
5482 received from network.
5484 * Fixed data reading from network in lib/silccore/silcpacket.c.
5485 The code now assures that all data is read from the fd and then
5486 continues packet processing. This was a bug fix since the code
5487 used to drop some data in some circumstances.
5489 * Added new function into lib/silcclient/client.[ch]:
5490 silc_client_start_key_exchange to start key exchange after
5491 connection has been established to server. The code internally
5492 now uses this funtion but its main purpose was to provide it
5493 for applications that perform their own connecting. After
5494 application has created a connection it merely calls this
5495 function to start the key exchange between client and server.
5496 The library takes care of everything else after that.
5498 Updated also lib/silcclient/README to explain the usage of
5501 * Do not send to application information that connection has
5502 been established. Application gets notified it by connect
5505 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Applied cras's patch to add silc_schedule_one function. The
5508 function runs scheduler once and returns.
5510 * Fixed the scheduler after cras messed it up. The timeout
5511 handling works now as it's supposed to work.
5513 * Added into lib/silccore/ silcnotify.h to include notify
5514 message types support. Changed silc_server_send_notify*
5515 functions, in server.[ch], to support those new notify types.
5516 Added the support for the notify types into client library,
5517 as well. Added new notify client operation into ops.h in
5520 * Changed silc_server_packet_send_to_channel to send normal
5521 packets instead of just channel message packets. The function
5522 is now used to send the notify packets to channels. It is not
5523 used to send channel message packets anymore, as server never
5526 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5527 va_arg()s as it seems to require it nowadays. I guess, if SILC
5528 is compiled with older va_arg() the new code should work anyway.
5530 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Splitted core library. Core library (lib/silccore) includes
5533 now only SILC protocol specific core (and common) components.
5534 Created new utility library (lib/silcutil) that includes more
5535 generic purpose stuff. The stuff for util library was taken
5536 from the old core library. This was minor and easy split.
5538 * Created SILC Client Library (lib/silcclient) that includes
5539 implementation of the SILC client without user interface. This
5540 was major move from silc/ directory. The code has been changed
5541 so that it is transparent towards the user interface. The
5542 silc/ directory includes now the same user interface as before
5543 and it uses the new client library. Read lib/silcclient/README.
5544 Basicly, the client library performs everything else related
5545 to SILC except user interface handling. Also, configuration
5546 files are considered to be part of user interface and library
5547 does not handle them.
5549 This change also changed a lot of structures, function naming etc.
5550 Most important change was that SilcClientWindow object was
5551 renamed to SilcClientConnection in the client library. Created
5552 also new file lib/silcclient/ops.h. Also added new files
5553 silc/local_command.[ch] and silc/client_ops.[ch].
5555 All these changes were made to make it easier for user interface
5556 designers to create what ever user interface for the SILC client
5559 It is also expected that the server will be moved to lib
5560 directory as well and SILC Server Library will be created;
5561 sometimes in the future.
5563 * Removed Local commands from lib/silccore/silccommand.h as
5564 they are application specific and new client library does not
5565 handle any of those anymore.
5567 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5568 old client implementation in silc/.
5570 * Added support for callback functions in SILC_LOG_* macros.
5571 Application can now set its own callbacks that will be called
5572 instead of using the default functions that will always print
5573 the debug messages to stderr (or stdout). Also, debugging can
5574 now be disabled by setting silc_debug to FALSE and re-enabled by
5575 setting it to TRUE. Note, that logging will still work even
5576 if debugging is disabled.
5578 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5579 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5580 silc_log_reset_debug_callbacks.
5582 * To enable debugging in silc client one must give now -d
5583 option on command line.
5585 * Changed silc_schedule_init to automatically allocate task queues
5586 if they are not allocated before calling it.
5588 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Added GMP 3.1 into math library.
5592 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5594 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5595 a channel in SILC network. The packet is used by servers and
5596 routers to notify other routers that user has left a channel.
5597 This little feature was missing until now. Added the feature
5598 to protocol specification as well.
5600 Added functions: silc_server_send_remove_channel_user and
5601 silc_server_remove_channel_user into server.[ch].
5603 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5604 lib/silccore/silcpacket.h. However, they are not implemented
5607 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Fixed joining to a channel and sending channel messages
5610 between server and router. The channel message sending should
5611 now work inside a cell.
5613 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5615 * Fixed the private message sending between server and router.
5616 The private message sending should now work inside a cell.
5618 * Added silc_server_replace_id into server.[ch] to replace
5619 existing ID in the SILC network.
5621 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5622 and silc_idlist_replace_server_id into idlist.[ch] in server.
5624 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Fixed the server to server connections. Server can again now
5627 connect to router. Router to router connections probably does
5630 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Added dynamic protocol registering support. Now protocols can
5633 registered and unregistered on the fly. Patch by cras.
5635 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Added lib/contrib directory to hold routines that some platforms
5638 don't have but are needed by SILC.
5640 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5641 into lin/contrib to provide getopt() and getopt_long() for
5642 those who don't have it.
5644 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5646 * Added AWAY command to client. When away message is set and
5647 client receives a private message packet the client automatically
5648 replies to the sender with the away message.
5650 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5651 bug seemed to be the cause of recent problems when compiling
5654 * Added version detection support to SKE protocol specification
5655 and added the new changes to the SKE implementation as well.
5656 There were other minor changes in the SKE protocol as well.
5658 Many changes in lib/silcske/silcske.[ch] and in
5659 lib/silcske/payload.[ch].
5661 * Added ^U functionality, clear input line. Patch from cras.
5663 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Mainly small bugfixes on core library. Fixed some debugging
5666 logging and buffer overflow in silclog.c.
5668 * Updated config.sub and config.guess on the distribution tree.
5670 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Added command lagging support in server. Client may execute
5673 commands now only once in two seconds.
5675 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Optimized packet reception. MAC computation and checking is now
5678 also more optimized. A lot previously duplicated code is now
5679 used as generic by both client and server.
5681 * Fixed key pair generation in clientutil.c
5683 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Added into lib/silccore/silcbufutil.[ch] new function;
5686 silc_buffer_realloc.
5688 * Moved generic packet sending/encryption functions to
5689 lib/silccore/silcpacket.[ch] from client and server. Some
5690 rewriting of the functions.
5692 * Moved all generic packet reception/decryption functions to
5693 lib/silccore/silcpacket.[ch] from client and server. The
5694 packet processing is now much cleaner in both client and server.
5695 These were major changes in both client and server.
5697 * Created many common functions in server to do packet sending.
5698 Previously code were duplicated a lot, this has been removed
5701 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Rewrote major parts of the ID cache system. Don't know
5704 whether it is better now or not but at least the API is more
5707 * Major rewrite on ID cache stuff on client because of the ID
5708 cache API changes. Added idlist.c to client.
5710 * Also major rewrite on ID cache stuff on server as well.
5711 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5712 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5713 in hand, instead they are all put into the ID cache system now.
5714 All server_idlist_* routines uses ID cache now instead of
5715 traversing its own lists (those lists does not exist anymore).
5716 SilcIDList though still exists. Also, SilcXXXEntry's are
5719 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Finally made the SKE implementation compliant to the protocol
5722 specification. All mp integers are now binary encoded as
5723 opposed being HEX encoded.
5725 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5728 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5729 functions: silc_[encode/decode]_pem. Also added function
5730 silc_encode_pem_file to PEM encode with newlines ('\n') for
5733 * SILC public keys are now encoded either PEM or binary. Same
5734 option is for private keys as well. By default private keys
5735 are binary encoded and public keys PEM encoded. Silly HEX
5736 encoding were removed.
5738 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5739 function to create fingerprints.
5741 * Fixed a bug in SHA1; does not change the original data anymore.
5743 * Partly implemented INFO command on client and server side.
5744 Fixed CLEAR command. Changes to SERVER command; show current
5745 server(s) when giving command without arguments. Added
5746 VERSION command to client.
5748 * Added check to server that unregistered connections cannot
5749 execute commands (unless it is specificly allowed).
5751 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Fixed screen refresh.
5755 * Fixed channel joining bug from client. On some circumstances
5756 client tried to join to a channel it had already joined.
5758 * Added public key verification process into client's protocol.c.
5759 The client now verifies the public key from user and saves
5760 it into ~./silc/serverkeys/ directory.
5762 Added into: clientutil.[ch]: silc_client_verify_server_key.
5764 * Changed SKE protocol's silc_ske_initiator_finish function
5765 to accept callback function that verifies the received public
5766 key. Removed old silc_ske_verify_public_key function.
5768 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5771 silc_pkcs_private_key[_data]_set.
5773 * Made the password and public authentication more cleaner in
5774 server's protocol.c.
5776 * Removed historic and obsolete protocol `channel_auth' from
5777 both client and server.
5779 * Removed wrong way of sending command status messages from
5780 server to client in server's command.c. The old way violated
5781 protocol specification.
5783 Changes to silccore/silccommand.[ch]: removed
5784 silc_command_encode_status_payload -> not needed anymore,
5785 changed silc_command_encode_payload_va to accept extra
5786 argument on variable argument list. The argument type must
5787 now be provided to the function. Also, added new function:
5788 silc_command_encode_reply_payload_va which is same as
5789 normal command_encode_payload_va except command status type
5790 is provided as extra argument.
5792 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Added ~./silc directory handling. The directory includes the
5795 public and private keys for the client.
5797 Added silc_client_check_silc_dir, silc_client_create_identifier
5798 and silc_client_load_keys.
5800 * Implemented SILC protocol compliant public key. Added public
5801 and private key saving to and loading from files.
5803 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5804 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5805 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5806 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5807 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5809 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5810 silc_pkcs_load_[public/private]_key.
5812 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Added silc_server_get_route (route.[ch]) to get connection
5815 data for the fastest route for given ID.
5817 * Implemented INVITE command on client and server. The command
5818 were re-defined in the SILC Protocol Specification and the
5819 implementation now complies with the specification.
5821 * Implemented PING command on client and server.
5823 * Implemented NAMES command on client and server. The server side
5824 supports currently only normal server not router server yet.
5825 Some changes to NAMES definition in SILC protocol specification.
5827 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Implemented LEAVE command on client and server.
5831 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5832 again. This change was made to the protocol as well. Server
5833 should not violate the protocol specification anymore.
5835 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5838 was tested. SOCKS4 was not but should work anyway.
