57 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
59 * Assure that silc_client_notify_by_server_resolve does not
60 resolve the client information multiple times. If it cannot
61 be found by the first it cannot be found at all. Affected
62 file lib/silcclient/client_notify.c.
64 * Fixed WHOWAS command reply calling. Affected file
65 lib/silcclient/command_reply.c.
67 * Removed all references to silc_idlist_get_client from the
68 Irssi SILC client since that call is internal call used by
69 the library. The Irssi SILC client will use now client
70 retrieval functions found in silcapi.h.
72 * Fixed a bug in resolving nickname info before sending
73 private message. It used freed memory. Affected file
74 irssi/src/silc/core/silc-servers.c.

156 Make sure also that USERS command reply does not resolve
157 twice information. Affected file is
158 lib/silcclient/command_reply.c.
160 Make sure that silc_client_get_clients_by_list does not
161 resolve twice same information.
163 * Check for valid client->id in the silc_server_free_client_data.

189 * Redefined the SILC packet header to include the padding
190 length. Affected file lib/silccore/silcpacket.[ch].
192 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
193 length for maximum padding up to 128 bytes). Affected
194 file lib/silccore/silcpacket.h.
196 * Removed all backwards support for old 0.5.x MAC thingies.
197 The SILC packet header change makes it impossible to be
198 backwards compatible.
200 * Send the ENDING packet with timeout in the backup resuming
201 protocol. This is to assure that all routers has connected
202 to the primary router. Affected file silcd/server_backup.c.
204 * Changed the RNG to take the first IV from random data. It
205 used to take it from zero actually. Changed the RNG also
206 to use /dev/urandom during session. /dev/random is used
207 in initialization. Affected file lib/silccrypt/silcrng.[ch].
209 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
211 * Changed the SILC packet header to have the first two bytes
212 (the packet length) encrypted. Affected files aroung the
213 code tree, lib/silccore/silcpacket.[ch]. Removed the
214 SilcPacketCheckDecrypt callback. It is not needed anymore
215 since the silc_packet_receive_process will determine now
216 whether the packet is normal or special.
218 * Implemented the unidirectional MAC keys. Affected files
219 lib/silcske/silcske.c, silcd/protocol.c and
220 lib/silcclient/protocol.c.
222 * Implemented the packet sequence number to the MAC computation.
223 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
224 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
225 lib/silcclient/protocol.c.
227 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
229 * Allow backup router to announce servers. All servers
230 announced by backup router are added to the global list
231 automatically. Update hte server's socket to our primary
232 router also when backup router announces a server.
233 Affected file silcd/packet_receive.c.
235 * Do not update the client->router in the function
236 silc_server_udpate_clients_by_server if the client is on
237 global list. We might fail to find any specific server
238 for locally connected clients and local cell clients. They
239 should still use the `from' and not `to' as client->router.
240 This fixes backup router resuming protocol. Affected file
243 * Decrease channel statistics count only if the channel
244 deletion worked. Affected files are silcd/server.c and
247 * Added silc_server_update_servers_by_server to update origin
248 of all server entries. Used during backup router protocol.
249 Affected files silcd/server_util.[ch], silcd/server.c. and
250 silcd/backup_router.c.
252 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
253 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
254 silc_hmac_get_hash and silc_hmac_get_name. Affected file
255 lib/silccrypt/silchmac.c.
257 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
259 * Assure that router cannot reroute the same channel message
260 to the sender. Affected file silcd/packet_receive.c.
262 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
264 * Made better checks that the channel message is not sent
265 to the router it came from. Affected file is
266 silcd/packet_send.c. Fixed memory leak too.
268 * Announce informations for incoming router connection, but
269 only after checking if it is replaced by backup router.
270 Affected file silcd/packet_receive.c.
272 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
274 * Fixed the backup resuming protocol to work in multiple
275 router environment. Affected file silcd/server_backup.c.
277 * Route packet only to one router in the function
278 silc_server_packet_send_to_channel. Affected file is
281 * Fixed silc_server_send_notify_dest to set the broadcast
282 flag. Fixed the silc_server_send_notify_topic to actually
283 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
284 Affected file silcd/packet_send.c.
286 * Changed the SFTP Filesystem interface. Changed the
287 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
288 the filesystem operation function. The SilcSFTPFilesystem
289 is now a context that is allocated by all filesystem allocation
290 functions and it already includes the operations structure
291 and filesystem specific context. It is given as argument
292 now to the silc_sftp_server_start. This made the interface
293 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
294 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
296 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
298 * Changed the backup router adding and getting interfaces
299 in the server. The router that will be replaced by the
300 specified backup router is now sent as argument. Affected
301 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
304 * Added silc_net_addr2bin_ne to return the binary form of
305 the IP address in network byte order. Affected files
306 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
308 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

322 protocol specification.
324 * Removed one redundant channel key generation from normal
325 server during joining procedure. Removed one redundant
326 channel key sending from server to router during joining
327 procedure. Affected file silcd/command.c.
329 * Made minor bugfixes to the backup router resuming protocol.
330 Affected file silcd/server_backup.c, server.c.
332 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

335 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
338 * Implemented the backup resuming protocol that is used to
339 resume the primary router position in the cell after the
340 primary router comes back online. Affected files
341 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
342 and silcd/server_util.[ch].

350 send any data. Affected file silcd/packet_send.c.
352 * Assure that if outgoing data buffer is pending do not force
353 send any data. Affected file lib/silcclient/client.c.
355 * Implemented the backup router support when the primary router
356 goes down. The servers and routers can now use the backup
357 router as new primary router without loosing connectivity.
359 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
361 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
362 in the server to indicate disabled entry. All data read
363 from the connection will be ignored and no data is sent
364 for entry that is disabled. Affected files are
365 silcd/idlist.h, silcd/server.c.
367 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
369 * Created SFTP client and server test programs in the
370 lib/silcsftp/tests directory.
372 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
374 * Implemented memory filesystem (virtual filesystem) for
375 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
378 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
380 * Implemented the SFTP (SSH File Transfer Protocol) to the
381 lib/silcsftp. It includes SFTP client and SFTP server
384 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
386 * Moved lib/silccore/silcprotocol.[ch] to the
387 lib/silcutil library.
389 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
390 take variable argument list pointer as argument. Affected
391 file lib/silcutil/silcbuffmt.[ch].
393 * Added silc_buffer_set function that is used to set data
394 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
395 Affected file lib/silcutil/silcbuffer.h.
397 * Changed various routines in the core library to use the new
398 silc_buffer_set instead of allocating new buffer only for
401 * Added 64-bit value formatting and unformatting support to the
402 silc_buffer_[un]format routines. Affected file is
403 lib/silcutil/silcbuffmt.[ch].
405 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
406 to includes/bitmove.h.
408 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
410 * Fixed channel user mode saving in client library. Affected
411 file lib/silcclient/command[_reply].c.
413 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
415 * Defined the file transfer to the SILC Protocol. Added
416 new packet type SILC_PACKET_FTP and defined File Transfer
417 Payload. The mandatory file transfer protocol is SFTP
418 (SSH File Transfer Protocol). Affected file in addition
419 of the internet draft is lib/silccore/silcpacket.h.
421 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
422 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
423 is used as part of backup router protocol when the primary
424 router of the cell is back online and wishes to resume
425 the position as primary router.
427 * Redefined the MAC generation keys in the protocol. The
428 same key is not used anymore in both direction. Both
429 direction will now use different keys for sending and
430 receiving. This fixes a potential security flaw. This
431 change causes incompatibilities in the protocol.
433 * Redefined also the MAC computation from the packet.
434 An packet sequence number is now added to the MAC
435 computation. This prevents possible replay attacks against
436 the protocol. This change too causes incompatibilities
439 Added `sequence' field to the SilcPacketContext to hold
440 the current sequence number for the packet.
442 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
444 * Added `created' field to the SilcIDListData in the file
445 silcd/idlist.h to indicate the time when the entry was
448 * Added `created' field to the SilcChannelEntry too. Affected
451 * Added `creation_time' aguments to all the announcement functions
452 in the server. If it is provided then only the entries that
453 was created after the provided time frame are actually
454 announced. Affected file silcd/server.[ch].
456 * The protocol says that the Channel ID's IP address must be
457 based on the router's IP address. Added check for this in
458 the silc_server_new_channel when processing incoming New Channel
459 Payload. Affected file silcd/packet_receive.c.
461 * Print out the correct version with --version in SILC client.
462 Affected file irssi/src/silc/core/silc-core.c.
464 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

467 entry always, not just when the command is coming from client.
468 Affected file silcd/command.c.
470 * Added new function silc_server_packet_queue_purge to purge the
471 outgoing data queue to the network. After the function returns
472 it is guaranteed that the outgoing packet queue is empty.
473 Affected file silcd/packet_send.[ch].
475 * Purge the outgoing packet queue in the rekey protocol's final
476 callback to assure that all rekey packets go to the network
477 before quitting the protocol. Affected file silcd/server.c.
479 * Added silc_client_packet_queue_parse as similar function as
480 in server to the client library. The affected file is
481 lib/silcclient/client.c.
483 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
485 * Splitted silcd/server.c and created silcd/server_util.[ch]
486 for utility functions.
488 * Added new socket flag SILC_SF_DISABLED to indicate that the
489 connection is open but nothing can be sent to or received from
490 the connection. Affected file lib/silcutil/silsockconn.[ch].
491 The checking for disabled socket is checked in the low level
492 silc_socket_write and silc_socket_read functions.
494 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
496 * Allow only nicknames and channel names that fits into the
497 7-bit unsigned char ASCII set. Affected file silcd/command.c.
499 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
501 * When processing JOIN command reply in server check that if
502 the channel exists in our global list we'll move it the local
503 list. Affected file silcd/command_reply.c.
505 * Fixed the check whether client is joined on the channel already
506 in JOIN command. Affected file lib/silcclient/command.c.
508 * Fixed the JOIN command reply to check whether the channel
509 already exists. Affected file lib/silcclient/command_reply.c.
511 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
513 * Added silc_ske_status_string to map the SKE error numbers
514 to readable strings. The affected files are
515 lib/silcske/silcske[_status].[ch].
517 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
519 * Do not show the private channels on the WHOIS channel list
520 as it is not allowed by the protocol. The affected file is
523 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Assure that the packet length digged from the actual packet
526 is something sensible in the silc_packet_decrypt_rest_special
527 in lib/silccrypt/silcpacket.c.
529 * Free and NULL the allocated pointer in silc_hmac_alloc if
530 the HMAC allocation fails. The affected file is
531 lib/silccrypt/silchmac.c.
533 * Print the selected security properties to the log files in
534 the server. Affected file silcd/protocol.c.
536 * Add SKE's reference counter even if calling the completion
537 callback manually. Otherwise it goes negative, although it
538 does not cause any problems. The affected file is
539 lib/silcske/silcske.c.
541 * Remove the client entry with short timeout after giving the
542 KILL command. Affected file lib/silcclient/command.c.
544 * Fixed to send error reply in WHOIS and IDENTIFY commands in
545 case all found clients are already disconnected (WHOWAS would
546 found them) in the server. Affected file silcd/command.c.
548 * Update the last_receive (time of last data received) to be
549 updated only when received private or channel message so that
550 the idle time showed in WHOIS makes more sense.
552 * Added boolean field `valid' in to the SilcClientEntry in the
553 client library to indicate whether the entry is valid or not.
554 This fixes the nickname change bug on channel when changing
555 the nickname to be same than the old (like nick to Nick) the
556 nickname formatter doesn't set the new nick anymore to Nick@host.
557 Affected file lib/silcclient/idlist.[ch].
559 * Now actually fixed the nickname changing on disconnection.
560 Added new function silc_change_nick to the Irssi SILC Client.
561 Affected file irssi/src/silc/core/client_ops.c,
562 irssi/src/silc/core/silc-nicklist.[ch].
564 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
566 * Check that the public key exists in the GETKEY command before
567 trying to encode it. Affected file silcd/command.c.
569 * Print some notifications on received public keys with GETKEY
570 command in the Irssi SILC Client. Affected files are
571 irssi/src/fe-common/silc/module-formats.[ch],
572 irssi/src/silc/core/client_ops.c.
574 * Use IDENTIFY command to resolve the server information in the
575 GETKEY command instead of INFO command. Affected file
576 lib/silcclient/command.c.
578 * All command reply functions in the client library now calls
579 the pending command reply callbacks even if an error has
580 occurred. The server has done this a long time and now it was
581 time to move the client library to this as well. Now all
582 errors can be delivered back to the pending command reply
583 callbacks if necessary. Affected files are
584 lib/silcclient/command[_reply].[ch].
586 * Change the nickname on disconnection back to the username
587 because in reconnect the server will enforce it to it anyway.
588 Affected file irssi/src/silc/core/silc-servers.c.
590 * Fixed a config file parsing bug in the Irssi SILC client.
591 Affected file irssi/src/silc/core/clientconfig.c.
593 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
595 * When printing the channel mode on JOIN, verify that the
596 channel key and channel's HMAC are valid. Affected file
597 irssi/src/silc/core/client_ops.c.
599 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
601 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
602 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
603 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
605 * Removed channel key rekey task deleting from the function
606 silc_server_save_channel_key. Affected file silcd/server.c.
607 Added explicit timeout task context instead that is used to
608 delete the task if we are registering a new task before the
609 new task has elapsed.
611 * When channel key rekey occurs the client library now saves
612 the old channel key for a short period of time (10 seconds) and
613 is able to use it in case some is still sending channel
614 messages encrypted with the old key after the rekey. Affected
615 file lib/silcclient/[idlist.h|client_channel.c].
617 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Added check to the silc_server_new_id_real to not accept
620 new ID if it is the sender's own ID. Affected file is
621 silcd/packet_receive.c.
623 * Assure that we do not announce ourself or the one we've
624 sending our announcements when we're router and are announcing
625 servers to our primary router. Affected file silcd/server.c.
627 * Fixed silc_server_command_identify_check_client to assemble
628 correct WHOIS packet. It send corrupted WHOIS packet and
629 caused problem with router to router connections. Affected
630 file silcd/command.c.
632 Fixed also silc_server_command_whois_check the same way
633 as for the IDENTIFY command.
635 * Added new SilcIDListStatus to the server in the SilcIDListData
636 structure. The status now includes the current status of
637 the entry (like registered, resolved etc.). Affected file
638 silcd/idlist.[ch]. Defined a bunch of different status types
639 as well. This replaced the old boolean registered field as well.
641 Added resolve_cmd_ident field to the SilcClientEntry structure
642 too so that if the entry is for example being resolved so
643 another command may attach to the same pending command reply
644 without requiring to resolve the same entry again. This concept
645 should optimize the WHOIS and the IDENTIFY resolving under
646 heavy load by taking away unnecessary resolving for entries
647 that are being resolved already.
649 Added support for adding multiple pending commands for one
650 command idenfier. Affected file silcd/command[_reply].[ch].
652 * Fixed WHOIS and IDENTIFY save to remove the cache entry
653 before deleting the data. Otherwise the hash table will have
654 freed data in comparison functions. Affected file is
655 silcd/command_reply.c.
657 * Fixed silc_idlist_replace_client_id to add the new entry to
658 the cache with NULL nickname. Otherwise there will be invalid
659 memory as the nickname after the nickname is freed. Affected
660 file silcd/packet_receive.c.
662 * Fixed the silc_idlist_get_clients_by_hash. The entries was
663 saved into wrong slots because the previous number of entries
664 was not taken into account. Affected file silcd/idlist.c.
665 Fixed same thing in silc_idlist_get_clients_by_nickname too.
667 * If we are router and we receive JOIN notify to a channel that
668 does not have any users then notified client is marked as the
669 channel founder, as it is it. The affected file is
670 silcd/packet_receive.c
672 * Added to the extended hash table API's table_del_*ext functions
673 the destructor as argument too, so that the caller can decide
674 which destructor to use or whether to use destructor at all.
675 Affected file lib/silcutil/silchashtable.[ch].
677 * Fixed ID Cache purging. It actually deleted the entries from
678 the hash table after the data was freed. The hash table ended
679 up comparing freed memory. The affected file is
680 lib/silccore/silcidcache.c.
682 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
684 * Fixed Irssi SILC client's KILL command's HELP syntax.
686 * The USERS command now resolves the detailed user information
687 if the userinfo field is missing. Affected file is
688 lib/silcclient/command_reply.c.
690 * Do not print error in silc_file_read if the read file does
691 not exist. Just silently return NULL. Affected file is
692 lib/silcutil/silcutil.c.
694 * Fixed the silc_log_output to not wine about NULL filename
695 and to not create some bogus " " filename. Affected file is
696 lib/silcutil/silclog.c.
698 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Fixed various printing bugs on the user interface in the
701 Irssi SILC Client. Minor changes that were forgotten from
704 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
706 * Fixed the configure.in.pre and the compilation and distribution
707 environment to support the new autoconf 2.52. That version is
708 now required to compile the CVS trunk.
710 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
712 * Renamed function silc_parse_nickname to silc_parse_userfqdn
713 to generally parse user@fqdn format strings. Affected file
714 lib/silcutil/silcutil.c.
716 * Added nickname_format and nickname_force_format fields to the
717 SilcClientParams structure. The first one defines the format
718 for the nicknames that the library will enforce if the receives
719 multiple same nicknames. The second one is boolean value and
720 can be used to force the library to always enforce the format
721 to the nicknames regardles whether there are multiple nicknames
722 or not. This configurable formatting was employed to flexibly
723 support accessing multiple nicknames from the user interface.
724 The userinterface can now set the nicknames to what ever format
725 they prefer. Affected file lib/silcclient/silcapi.h.
727 Added function silc_client_nickname_format to the file
728 lib/silcclient/idlist.c. It performs the nickname formatting.
730 Added new field `hostname´ to the SilcClientEntry context.
731 It holds the hostname of the client. Affected file is
732 lib/silcclient/idlist.h.
734 * Irssi SILC Client sets the nicknames in nick@hostn format.
735 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
736 irssi/src/silc/core/silc-core.c.
738 The WHOIS printing now also shows both the real nickname and
739 the formatted nickname so that user knows how to access the
740 user if there are multiple same nicknames cached. Affected
741 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
742 printing formatting too to take the hostname now as a separate
743 argument. The Affected file is
744 irssi/src/fe-common/silc/modules-formats.[ch].
746 * Changed the silc_client_get_clients_local to accept the formatted
747 nickname as argument. It accepts the real nickname too but the
748 formatted nickname can be used to find the true entry from
749 multiple entries. Affected file lib/silcclient/silcapi.h and
750 lib/silcclient/idlist.c.
752 * Added nickname_format_parse field to the SilcClientParams.
753 It is a callback function provided by the application to parse
754 the nickname out of the formatted nickname string. The library
755 calls it to get the nickname from the formatted string. Since
756 the application generally knows better the format of the nickname
757 string it parses it instead of the library, even though library
758 encodes the formatted string. If the callback function is not
759 provided then the library will use the string as is. The
760 affected file is lib/silcclient/silcapi.h.
762 * All the nickname strings passed to the client library in
763 commands are now expected to be formatted nickname strings.
764 If the command does not support the formatted nickname string
765 it will assume that the sent string is the actual nickname.
766 Affected file lib/silcclient/command.c.
768 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
770 * Added public key authentication support to OPER and SILCOPER
771 commands in the client library. Affected file is
772 lib/silcclient/command.c.
774 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
776 * Changed the get_auth_methdod client operation to be asynchronous.
777 It can be async if the application resolves the authentication
778 method from the server during the negotiation. Added new
779 SilcGetAuthMeth completion callback that the application will
780 call after resolving the authentication method.
782 Added function silc_client_request_authentication_method that
783 the application can use to resolve the authentication method
784 from the server. Added also SilcConnectionAuthRequest callback
785 that the library will call after the server has replied. The
786 application can call this function if it does not know the
787 current authentication method.
789 Affected files are lib/silcclient/client.c and
790 lib/silcclient/silcapi.h.
792 * The Irssi SILC client now automatically resolves the authentication
793 method incase any configuration information is not present (and
794 currently there never is). The affected file is
795 irssi/src/silc/core/client_ops.c.
797 * Fixed public key authentication from the client library.
798 Affected file lib/silcclient/protocol.c. Changed also the
799 protocol specification about the public key authentication in
800 the connection authentication protocol. The actual data to be
801 signed is now computed with a hash function before signing.
803 * Fixed the public key authentication from the server as well.
804 Affected file silcd/protocol.c.
806 * Removed the mlock()'s from the memory allocation routines.
807 Affected file lib/silcutil/silcmemory.c. The ./configure does
808 not check anymore for the mlock(). Affected file is
811 * Fixed USERS command in server to allow the execution of the
812 command for private and secret channels if the client sending
813 the command is on the channel. Affected file silcd/command.c.
815 * Fixed silc_client_get_clients_local to return the clients
816 count correctly. It could return wrong value. Affected file
817 lib/silcclient/idlist.c.
819 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
822 types. The assembler optimizations seemed not to like 64-bit
823 data types. The assmebler optimizations thus are now enabled
824 also for BSD systems as opposed to only enable them for Linux.
826 * Do not check for threads at all on BSD systems. Affected
827 file configure.in.pre.
829 * Removed -n and -h options from the Irssi SILC Client since
830 they are not used in silc.
832 * Fixed the prime generation to assure that the first digit
833 of the generated random number is not zero since our conversion
834 routines does not like number strings that starts with zero
835 digit. If zero digit is seen the random number is regenerated.
836 This caused some corrupted RSA keys when the zero first digit
837 was met. Affected file lib/silcmath/silcprimegen.c.
839 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Fixed WIN32 configuration in the ./configure script.
842 Fixed to include xti.h on environments that has it.
843 Patches by Carsten Ilchmann and andrew.
845 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
847 * Changed the silc_id_create_client_id to be collision
848 resistant. It is now assured that there cannot be created
849 two same client ID's. I suspect that some weird bugs in
850 the server were actually caused by duplicate Client IDs.
851 Affected file silcd/serverid.[ch]. A router receiving
852 new ID now also assures and informs the sending server
853 if the ID caused collision.
855 * Changed the silc_id_create_channel_id to also assure that
856 there are no collisions.
858 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
860 * Statement about ignoring the Mutual Authentication flag when
861 performing rekey with PFS was a bit misleading. It is ignored
862 if it was set in the initial negotiation, it cannot be even
863 set in the rekey. Fixed in the ke-auth draft. Started the
864 new versions of the protocol drafts in the doc/.
866 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
868 * Fixed a bug in silc_client_command_identify_save when saving
869 new channel information. The channel name was no duplicated
870 and caused crash on exit. Affected file is
871 lib/silcclient/command_reply.c.
873 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
875 * Fixed the getkey command handling in the server. Send just
876 empty OK reply to the sender if the key could not be fetched
877 (but everything else was ok, like the key just was not available).
878 Changed the public key parameter to optional in the protocol
879 specs so that empty OK reply can be sent. Affected file
882 Added a message to Irssi SILC client to tell to user if the
883 server did not return a public key.
885 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
887 * Fixed a channel key regeneration bug. It registered new
888 timeout tasks exponentially until all system resources were
889 used. Affected file silcd/server.c.
891 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Added the SILC Document generator to the scripts/silcdoc.
894 It can be used to generate the Toolkit Reference Manual out
895 of the source tree. Internally it will also use the RoboDoc
896 generator now imported in util/robodoc.
898 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
900 * Added couple of return's in rekey protocol if error orccurred
901 during the protocol. The execution must be terminated.
902 Affected file silcd/protocol.c. Also, terminate the protocol
905 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
907 * The client's Client ID was created initally from the wrong
908 nickname (it could have been in format nick@host) in the
909 silc_server_new_client. Affected file silcd/packet_receive.c
911 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
913 * Added some SILC_LOG_ERROR's to various error conditions
914 if client could not be added to ID cache. Affected files
915 silcd/packet_receive.c and silcd/server.c.
917 * When client's sock->user_data is freed, NULL also the
918 client->router and client->connection pointers. Added check
919 for these pointers being NULL to various places around the
920 code. Affected file silcd/server.c.
922 * Added client->data.registered == TRUE checks to various
923 places around the code to assure that unregistered client's
924 are not handled when it is not allowed. Affected file
927 * Added `bool registered' fields to all
928 silc_idlist_[server|client]_get_* routines to indicate whether
929 the fetched client needs to be registered or not. Affected
930 file silcd/idlist.[ch].
932 * Add your own entry as registered to the ID cache in the
933 server. Affected file server.c.
935 * Fixed a bug in silc_server_new_server. The SilcServer was
936 set as the new server's context instead of SilcServerEntry.
937 This naturally caused some weird bugs.
939 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
941 * Do not delete the channel rekey task when adding it
942 for in silc_server_create_channel_key.
944 * Changed the silc_server_create_channel_key to return
945 TRUE or FALSE to indicate the success of the channel key
948 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Fixed MSVC++ project files and added missing files to
951 Makefiles under win32/.
953 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Do not add TCP_NODELAY flag if the operating system
956 does not have it defined. Affected files are
957 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
959 * Fixed buffer overflow from Irssi SILC Client. Affected
960 file irssi/src/fe-common/core/themes.c.
962 * Fixed double free in client library in the file
963 lib/silcclient/client.c when disconnecting from server.
965 * Applied double free patch from cras to Irssi SILC client.
966 Affected files irssi/src/core/[modules/expandos].c
968 * Fixed the disconnection handling to Irssi SILC Client.
969 The application must call silc_client_close_connection
970 in ops->connect client operation in case of failure of
971 the connection. Affected file is
972 irssi/src/silc/core/client_ops.c.
974 * Do not set sock->protocol to NULL in the function
975 silc_client_close_connection after executing the protocol's
976 final callback since the sock might not be valid anymore.
977 Affected file lib/silcclient/client.c.
979 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Do not enable SILC_THREADS if the linking with libpthread
982 did not happen. Affected file configure.in.pre.
984 * Added notion to protocol specification that server must
985 verify the sent authentication payload with CMODE when
986 setting the channel founder key. Implemented it to the
987 server. Affected file silcd/command.c.
989 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
991 * Added _EXTRA_DIST SILC distribution variable to the
992 distributions file. It is used to conditionally add extra
993 files or directories to the specific distribution. Affected
994 files ./prepare, Makefile.am.pre and distributions.
996 Removed the `_' from the start of the distribution names.
999 * Added README.WIN32 for instructions to compile the Toolkit
1002 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1004 * Fixed a double free in disconnection in the server. Affected
1005 file is silcd/server.c.
1007 * Fixed the lib/silcske/groups.c to work now also with GMP
1008 MP library. The string conversion did not work when using
1009 specific base and the base is indicated in the string as well.
1011 * Created win32/ directory which now includes MSVC++ specific
1012 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1013 It will appear only in the toolkit distribution
1015 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Changed the key material distribution function in case when
1018 the hash output is too short. The data is now concatenated
1019 a bit differently than it used to. Made the change to the
1020 SKE protocol specification.
1022 * Added better GMP detection to configure.in.pre. A patch
1025 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1027 * Fixed a minor bug in SKE that might cause some problem on
1028 some platforms. Affected file lib/silcske/silcske.c.
1030 * Added the cookie checking for initiator in the SKE. It checks
1031 that the responder returns the sent cookie unmodified. The
1032 affected file is lib/silcske/silcske.c. Added new SKE
1033 error type INVALID_COOKIE that can be sent during the
1034 negotiation. Fixed some memory leaks as well.
1036 * Added the "invalid cookie" error message to Irssi SILC client's
1039 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Added `task_max' field to the SilcClientParams to indicate
1042 the maximum tasks the scheduler can handle. If set to zero,
1043 default values are used. Affected file lib/silcclient/silcapi.h.
1045 * Fixed memory leaks in silc_client_close_connection. Affected
1046 file lib/silcclient/client.c.
1048 * Added silc_client_del_client_entry to client library to free
1049 all memory of given client entry. Affected file is
1050 lib/silcclient/idlist.[ch].
1052 * Added new functions silc_client_del_channel and
1053 silc_client_del_server to delete channel and server entries.
1054 Affected file lib/silcclient/[silcapi.h/idlist.c].
1056 * Removed silc_client_del_client_by_id from silcapi.h.
1058 * Fixed the INFO command to return the server's own info
1059 correctly when querying by Server ID. Affected file is
1062 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Removed the non-blocking settings in WIN32 code in the
1065 silc_sock_[read/write] and added SleepEx instead. Affected
1066 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1067 of input data is now checked with FIONREAD and ioctlsocket.
1069 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Call silc_schedule_task_del_by_context in the
1072 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1073 Affected file lib/silccore/silcprotocol.c.
1075 * Call silc_protocol_cancel for active protocols in the
1076 silc_server_close_connection if the funtion
1077 silc_server_free_sock_user_data has not been called.
1078 Affected file silcd/server.c.
1080 * Generic tasks cannot be deleted using the del_by_fd
1081 task deleting function since generic tasks does not match
1082 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1084 * Added a notion to SILCOPER help file that the SILCOPER works
1085 only on router server, not on normal server.
1087 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Added for WIN32 support for the new scheduler as well.
1090 Affected file lib/silcutil/win32/silcwin32schedule.c.
1092 * Fixed the SHA1 implementation to work on various platforms.
1094 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1096 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1097 API. It is part of the scheduler now. Everything else is
1098 as previously but some functions has changed their names.
1099 Checkout the lib/silcutil/silcschedule.h for the interface.
1100 Updated all applications to use the new interface. Affected
1101 files are lib/silcutil/silcschedule.[ch].
1103 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Found a bug in the SKE implementation. The HASH value,
1106 specified by the protocol, was not computed correctly. The
1107 public key of the responder was not added to the computation
1108 even though it is mandatory. Affected file lib/silcske/silcske.c.
1109 This unfortunately causes incompatibilities with older
1110 clients and servers.
1112 * Added WIN32 specific network init and uninit functions:
1113 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1114 the Winsock2. Affected file lib/silcutil/silcnet.h and
1115 lib/silcutil/win32/silcwin32net.c.
1117 * Set the socket always to nonblocking mode on WIN32 after
1118 reading data or writing data. Affected file is
1119 lib/silcutil/win32/silcwin32sockconn.c.
1121 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Fixed various compilation problems under WIN32. Affected
1124 files lib/silcutil/win32/silcwin32thread.c and
1125 lib/silcutil/win32/silcwin32schedule.c.
1127 * Removed all _internal.h #includes from public header
1128 files. Internal headers must never be included from
1131 Removed also the lib/silcske/payload_internal.h file.
1133 * All include files that may be needed (public and some others
1134 included by the public headers) by application developers are
1135 now copied to the ./includes directory. It does not copy any
1136 internal headers. Affected file Makefile.defines.pre and all
1137 Makefile.am's under lib/ and subdirs.
1139 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1141 * Do not change the ~/.silc directory's permissions automatically.
1142 Affected file irssi/src/silc/core/clientutil.c.
1144 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1146 * Do not cancel the protocol in silc_server_close_connection
1147 it might cause recursion. Now cancelled in the function
1148 silc_server_free_sock_user_data. Affected file silcd/server.c.
1150 * Fixed the silc_server_remove_clients_by_server to regenerate
1151 the channel keys correctly finally. Added also new function
1152 silc_server_remove_clients_channels to actually do it.
1153 Affected file silcd/server.c.
1155 * Fixed the silc_server_new_channel to not crash by giving
1156 wrong router to the new channel. Affected file is
1157 silcd/packet_receive.c.
1159 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1161 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1162 which is given as argument to the silc_client_alloc now.
1163 It can be used to configure the client and set various parameters
1164 that affect the function of the client.
1166 * The USERS command in server did not check whether the channel
1167 is private or secret. Affected file silcd/command.c.
1169 * Added new argument to the USERS command in protocol specification.
1170 The USERS command now can take the channel name as argument
1171 as well. Added support for this in client and server and
1172 updated the protocol specs.
1174 * Completed the GETKEY command in client. It can be now used
1175 to fetch also servers public key not only some clients.
1176 Affected files lib/silcclient/command[_reply].c.
1178 * Added silc_client_get_server to return server entry by the
1179 server name. Affected files lib/silcclient/silcapi.h and
1182 * Redefined the IDENTIFY command in protocol specification to be
1183 more generic. It now can be used to query information about
1184 any entity in the SILC Network, including clients, servers and
1185 channels. The query may be based either the entity's name
1186 or the ID. Added support for this in both client and server.
1188 Affected files silcd/command.c and lib/silcclient/command.c
1189 and command_reply.c.
1191 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1192 the _from_client and _from_server functions. Affected file
1195 * Added silc_client_get_channel_by_id_resolve to the file
1196 lib/silcclient/silcapi.h to resolve channel information by
1197 its ID. Added also silc_client_get_channel_by_id that
1198 does not resolve it from the server.
1200 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1202 * Added SilcServerEntry context into the client library
1203 to represent one server. The INFO command now allocates
1204 these to save the resolved server info. For now on the
1205 client library will also keep information about servers,
1206 connected and resolved with INFO.
1208 The INFO command now allocates the SilcServerEntry context
1209 and saves the server info there. The COMMAND_REPLY in
1210 the INFO now returns the parameters to application in
1211 same order as defined in the protocol specification.
1213 The entries are cached in the client->server_cache.
1215 * The INFO command is now issued after received the Client ID
1216 from the server. Affected file lib/silcclient/client.c.
1218 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1219 to the application as the mode changer might be server.
1220 It is guaranteed that NULL is not returned anymore to the
1221 application. Affected file lib/silcclient/client_notify.c.
1223 The ID Type is now also passed to the application so that
1224 it can check whether the returned entry is SilcClientEntry
1227 Added new function silc_client_get_server_by_id to return
1228 the server entry by ID. Affected files are the
1229 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1231 * Do not create the channel in the Irssi SILC Client when issuing
1232 the JOIN command but when received the sucessful JOIN command
1233 reply. Otherwise the channel might get created even though we
1234 could not join it. The Affected file is
1235 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1237 * Fixed a channel joining bug in router. The router must also
1238 check the channel modes, invite and ban lists etc. when serving
1239 the JOIN command sent by normal server. Affected file is
1240 silcd/command.c. The router now resolves the client's
1241 information from the server who sent the JOIN command if it
1242 does not know it, and processes the JOIN command only after
1245 * Changed the SilcCommandCb to take new argument; void *context2.
1246 Affected file lib/silccore/silccommand.h
1248 The second argument in the command callbacks in the server now
1249 includes the SilcServerCommandReplyContext if the command was
1250 called as pending command callback from the command reply.
1251 Otherwise it is NULL. When called as pending the status of the
1252 command reply will be checked and if it was erronous the
1253 error will be sent to the original sender of the command.
1254 This way the client always receives the error messages even
1255 though the server was actually the one who received the error
1256 when it resent the command to router, for example. Affected
1257 files silcd/command[_reply].[ch].
1259 * Fixed sending WHOWAS command's error message to client if
1260 the requested client could not be found. It was missing.
1263 * Changed the CMODE and CUMODE commands reply arguments in the
1264 protocol specification. The Channel ID is now sent in both
1265 of the commands to identify the channel. Implemented this
1266 new feature to the client and server. Affected files
1267 lib/silcclient/command_reply.c and silcd/command.c.
1269 * Made better checks for invite and ban lists in the JOIN
1270 command in server. Affected file silcd/command.c.
1272 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1274 * The server now performs the incoming host IP/DNS lookup
1275 using the silc_socket_host_lookup and thus does not block
1276 the server anymore. Affected file silcd/server.c.
1278 * Completed the multi-thread support for SILC Scheduler in
1279 the lib/silcutil/silcschedule.c.
1281 * Fixed the configure.in.pre to detect the pthread correctly
1284 * Fixed a deadlock in silc_task_queue_wakeup in the file
1285 lib/silcutil/silctask.c.
1287 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Added new function silc_schedule_wakeup that is used in
1290 multi-threaded environment to wakeup the main thread's
1291 schduler. It needs to be used when a thread adds a new task
1292 or removes a task from task queues. After waking up, the
1293 scheduler will detect the task queue changes. If threads
1294 support is not compiled in this function has no effect.
1295 Implemented the wakeup mechanism to both Unix and WIN32
1296 systems. Affected files are lib/silcutil/silcschedule.[ch],
1297 lib/silcutil/unix/silcunixschedule.c and the
1298 lib/silcutil/win32/silcwin32schedule.c.
1300 * Added new function silc_task_queue_wakeup to wakeup the
1301 scheduler by the specified task queue. Affected file
1302 lib/silcutil/silctask.[ch].
1304 * The silc_socket_host_lookup_start now wakes up the scheduler
1305 after adding the timeout task. Affected file is
1306 lib/silcutil/silcsockconn.c.
1308 * The silc_socket_host_lookup is synchronous now if the threads
1309 support is not compiled in. However, the callback is still
1310 called asyncronously through the scheduler, anyway. Affected
1311 file lib/silcutil/silcsockconn.c.
1313 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Added new function silc_socket_host_lookup to perform
1316 asynchronous IP and FQDN lookups for the socket connection.
1317 Affected files lib/silcutil/silcsockconn.[ch].
1319 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1322 that may or may not compile the mutex support in.
1324 Changed the silc_mutex_alloc interface. It allocates the
1325 mutex now to the sent pointer and returns TRUE or FALSE.
1327 Affected file lib/silcutil/silcmutex.h.
1329 * Wrote the SILC Task Queue interface to support multi-threads.
1330 Affected file lib/silcutil/silctask.[ch].
1332 * Wrote the SILC Scheduler to support multi-threads. Affected
1333 file lib/silcutil/silcschedule.c.
1335 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1337 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1338 in lib/silcutil/win32/.
1340 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Defined SILC Mutex API and SILC Thread API and implemented
1343 them for Unix. Affected files are
1344 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1345 lib/silcutil/unix/silcunixmutex.c and
1346 lib/silcutil/unix/silcunixthread.c.
1348 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Fixed the silc_server_remove_clients_by_server's channel
1351 key re-generation. The hash table handling was incorrect
1352 and would not work with many channels. Affected file is
1355 * Fixed some memory leaks around the server code.
1357 * Rewrote the silc_server_get_users_on_channel to support IPv6
1358 based Client ID's. Affected file silcd/server.c.
1360 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1361 specification. However, a separate document must be written
1362 to define the detailed signing procedure and the payload
1363 associated with the flag. Defined the flag to the
1364 lib/silccore/silcchannel.h as well.
1366 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1368 * Changed the dynamic tables to static size tables in the
1369 lib/silccrypt/silchmac.c.
1371 * Removed GCC dependencies from the code. A patch by cras.
1373 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1375 * Do not show the error "Error receiving packet bla bla"
1376 in server if it really was not an error (-2 means that reading
1377 is pending). Affected file silcd/server.c.
1379 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1381 * Fixed a possible crash in silc_server_remove_clients_by_server
1382 in silcd/server.c. Fixed there also some memory leaks.
1384 * Fixed the silc_idlist_replace_client_id. It could replace
1385 wrong key in the hash table. Affected file silcd/idlist.c.
1387 * Do not check whether there are global users on the channel
1388 if the channel->global_users is FALSE. Affected functions
1389 silc_server_remove_from_one_channel and
1390 silc_server_remove_from_channels in silcd/server.c. Also,
1391 do not check if the removed client is local as we can be
1392 sure that global client was not removed from the channel
1393 and checking for global users is not needed.
1395 * The silc_server_remove_clients_by_server now re-generates
1396 the channel keys correctly for those channels that had
1397 clients removed from them. Affected file silcd/server.c.
1399 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1401 * Found the reason of random crashes in the server. We weren't
1402 ignoring the SIGPIPE signal (which can be sent in write())
1403 and it crashed the server. Affected file silcd/silcd.c.
1405 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Assure that sock->user_data is not NULL in the function
1408 silc_server_packet_send in silcd/packet_send.c.
1410 * Disconnect the remote connection if it could not be added
1411 to any ID lists in the server. The affected file is
1414 * Check in silc_server_packet_send[_real/dest] that the
1415 socket is not disconnecting and ignore the data if it is.
1416 Affected file silcd/packet_send.c.
1418 * Define inline to __inline on native WIN32 compilation.
1419 Affected file includes/silcwin32.h.
1421 * Added some explicit type casts for inline code since MSVC
1422 require them. Affected files lib/silcutil/silcbuffer.h,
1423 lib/trq/silcdlist.h and lib/trq/silclist.h.
1425 * Print warning in log files from now on if the packet
1426 decryption fails. Affected file silcd/server.c.
1428 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Changed the `say' client operation's interface to accept
1431 new `type' argument to indicate the type of the message sent
1432 by the library. The application may filter the library's
1433 messages according the type. The affected file is the
1434 lib/silcclient/silcapi.h.
1436 * Added two new functions to lib/silcclient/silcapi.h:
1437 silc_client_del_client and silc_client_del_client_by_id.
1438 Affected file lib/silcclient/idlist.c.
1440 * Moved the clientincludes.h from includes/ to silc/ and
1441 serverincludes.h from includes/ to silcd/.
1443 * The modes for the CMODE and CUMODE are now passed as
1444 uint32 for application with COMMAND_REPLY. The affected
1445 file is lib/silcclient/command_reply.c.
1447 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1449 * /WHOIS without arguments shows client's own information.
1450 Affected file lib/silcclient/command.c.
1452 * Changed PING to not accept any arguments. The specs
1453 says that client can ping only the connected server so
1454 requiring an argument is not needed. Affected file is
1455 lib/silcclient/command.c.
1457 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Fixed a fatal bug in private message sending and reception
1460 encryption and decryption when using private message keys.
1461 The implementation was incorrect and did not follow the
1462 specification. It causd that some of the message were
1463 lost since it did not use the sending and receiving keys
1464 as the protocol suggests. This has been fixed and will cause
1465 incompatibilities with older clients when sending private
1466 message encrypted with private message keys. Affected files
1467 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1468 and various other in Irssi SILC Client.
1470 Added `responder' boolean argument to the functions
1471 silc_client_add_private_message_key[_ske] to indicate when
1472 the key is added as responder or initiator of the key
1475 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1477 * Removed the silc_ske_check_version function and created
1478 a SilcSKECheckVersion callback. Added also a function
1479 silc_ske_set_callbacks that is now used to set all SKE
1480 callbacks. The callback functions are not given to
1481 the SKE functions anymore, but this function is used to
1484 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1486 * Added `silc_version' argument to the silc_client_alloc
1487 to define the version of the application for the library.
1488 The library will use the version string to compare it
1489 against the remote host's (usually a server) version
1490 string. Affected file lib/silcclient/silcapi.h
1492 * Added the KE protocol context to Key Agreement context
1493 in client library so that we can abort the SKE if it
1494 is in process when we get timeout. Affected file is
1495 lib/silcclient/client_keyagr.c.
1497 * Do not resolve the client ID forever if it returns in the
1498 first time that such client does not exist. This was done
1499 for example with private message. Affected file is
1500 lib/silcclient/client_prvmsg.c.
1502 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Do not add regex.h for WIN32. The affected file
1505 includes/silcincludes.h.
1507 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1508 not work yet 100%. It generates the DLL's automatically
1509 when compiling with --with-win32 under cygwin.
1511 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1513 * lib/contrib/regex.c is not compiled on WIN32.
1515 * Added silc_net_get_socket_opt function to the
1516 lib/silcutil/silcnet.h.
1518 * Added includes/silcwin32.h for WIN32 specific includes
1521 * Do not use ptime structure or any of the posix process
1522 functions on WIN32 in lib/silccrypt/silrng.c.
1524 * Added silc_gettimeofday to provide generic function
1525 for struct timeval on all platforms. Added the function
1526 to lib/silcutil/silcutil.h.
1528 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1531 library as they clearly belong there. As a plus side we
1532 can make the actual socket connection routines platform
1535 Added also new generic function silc_socket_read and
1536 silc_socket_write (that used to be silc_packet_[read/write].
1537 The implementation of these are platform specific.
1539 * Added WIN32 specific routines of silc_socket_[read/write]
1540 to lib/silcutil/win32/silcwin32sockconn.c.
1542 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Added preliminary support for native WIN32 compilation under
1545 cygwin (using the -mno-cygwin option for GCC) to the
1546 ./configure.in.pre. The --with-win32 now prepares the
1547 compilation for native WIN32.
1549 * Rewrote the SILC Scheduler interface in the file
1550 lib/silcutil/silcschedule.h. The scheduler is now context
1551 based and does not have anymore any global static scheduler.
1552 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1553 and created lib/silcutil/win32 directory for WIN32 based
1556 * Added Unix specific network routines to the
1557 lib/silcutil/unix/silcunixnet.c and the old
1558 lib/silcutil/silcnet.c includes now only generic routines.
1560 Added WIN32 specific network routines to the
1561 lib/silcutil/win32/silcwin32net.c.
1563 * Added Unix specific utility functions from the
1564 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1566 * Added WIN32 SILC Scheduler to the file
1567 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1570 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Do not handle JOIN notify in the server if the target client
1573 is not registered (idata->registered == FALSE). The affected
1574 file is silcd/packet_receive.c.
1576 * Update the nickrec->founder in event_cumode in the Irssi SILC
1577 client. Affected file irssi/src/silc/core/silc-channels.c.
1579 * Fixed the CUMODE_CHANGE notify handling in the server when
1580 server and router are announcing their clients on channels.
1581 Now the mode changes are saved and notified correctly. The
1582 affected file is /silcd/packet_receive.c.
1584 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1585 They really did not replace the cache entry in the ID Cache.
1586 Now they do that. Affected file silcd/idlist.c.
1588 * Fixed the KICK notify handling in the Irssi SILC client to
1589 update the channel records so that the kicked client does not
1590 appear to be on the channel. The affected file is
1591 irssi/src/silc/core/silc-channels.c.
1593 * Always update the conn->current_channel when executing command
1594 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1596 * Fixed the KILL notify handling in Irssi SILC client to remove
1597 the killed client on all channels.
1599 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Fixed the silc_parse_command_line to remove extra spaces
1602 from the start and end of the arguments. Affected file is
1603 lib/silcutil/silcutil.c.
1605 * Cancel and free any active protocol in the function
1606 silc_server_close_connection. Affected file silcd/server.c.
1608 * Cancel and free any active protocol in the function
1609 silc_client_close_connction. Affected file is
1610 lib/silcclient/client.c.
1612 * Do not execute the KILL command for clients that are in
1613 history (ie. they are not in the network). Affected file is
1616 * Fixed KILL notify handling, client does not crash anymore.
1617 Affected file irssi/src/silc/core/silc-channels.c.
1619 * Reduced the default packet buffer size from 2048 to 1024 in
1620 lib/silccore/silcpacket.c.
1622 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1623 counter to the SKE context that is incresed when the SKE library
1624 performs async operation outside the library. If the outside
1625 process frees the SKE context and FREED status will be set
1626 and the library will detect after the sync operation that the
1627 libary is freed. The affected files are
1628 lib/silcske/silcske[_status].[ch].
1630 * Resolve the client entry information in the function
1631 silc_client_channel_message to assure that NULL pointer is not
1632 passed as client entry to the application. */
1634 * Fixed the task timeout calculation to assure that there is
1635 never negative timeouts. The affected file is
1636 lib/silcutil/silcschedule.c.
1638 * Fixed the channel user mode notification sending in server.
1639 It was sent point-to-point to the router (or to server by router)
1640 but it needs to be destined to a channel. The routines now
1641 supports sending the channel user mode notifys to the channels
1642 when announcing clients and channels. Affected files are
1643 silcd/server.c and silcd/packet_receive.c.
1645 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1646 It did not actually replace the old channel entry in the cache.
1647 Affected file lib/silcclient/client_notify.c.
1649 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Fixed a possible crash in silc_packet_send_prepare. It now
1652 assures always that there is enough space in the buffer and
1653 at the tail area of the buffer (for MAC).
1655 Fixed the inbound buffer reallocation in silc_packet_read.
1656 It was old code and did not handle the reallocation correctly.
1659 The affected file is lib/silccore/silcpacket.c.
1661 * Fixed buffer overflow in silc_parse_nickname in the file
1662 lib/silcutil/silcutil.c.
1664 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * make install generates new server keys only if there is not
1669 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1672 Added check that if the NOREPLY is set then we will not send
1673 the away message. This avoids infinite loop of away messages
1674 if both clients are away. The affected file is
1675 lib/silcclient/client_prvmsg.c.
1677 * Fixed client crash if /NICK was given without arguments.
1678 Affected file lib/silcclient/command.c.
1680 * Server does not send the invite list in INVITE command back
1681 to the client if the list was not altered. Added this notion
1682 to the protocol spec as well. Affected file silcd/command.c.
1684 Fixed possible crash in INVITE command by checking the
1685 value of silc_server_get_client_route command.
1687 * Fixed the INVITE notify type handling. The arguments are now
1688 taken in correct order and client does not crash. The affected
1689 file is irssi/src/silc/core/silc-channels.c.
1691 Removed the "Inviting xxx to channel" message from the
1692 client library away and let the application handle it.
1693 Affected file lib/silcclient/command.c. Added that message
1694 to Irssi SILC client's message formats.
1696 * Fixed CMODE command crash in client. It now checks the
1697 amount of arguments correctly and does not crash. The affected
1698 file is lib/silcclient/command.c.
1700 * Do not create new channel automatically in silc_channels_join
1701 but check whether the channel by that name already exists.
1702 Affected file irssi/silc/core/silc-channels.c.
1704 * Do not send the SERVER_SIGNOFF to router if the disconnected
1705 entity was the router. Affected file silcd/server.c.
1707 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1708 SILC client as it was missing from there.
1710 Added the handling of the KICK notify to the Irssi SILC client
1711 as it was missing. Added "you have been kicked" message to
1712 Irssi SILC client's message modules formats.
1714 Added the handing of the KILL notify to the Irssi SILC client
1715 as it was missing. Added the kill message module formats
1718 The affected file is irssi/src/silc/core/silc-channels.c.
1720 * The router did not save the channel mode the server announced.
1721 Affected file silcd/packet_receive.c.
1723 * Fixed a possible crash in INFO command in server. If the
1724 server did not provide the server info it crashed. Affected
1725 file silcd/command.c.
1727 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1729 * Fixed the GETKEY command in the server to check also the
1730 global list. Otherwise the GETKEY would not work correctly
1731 in normal SILC server. Affected file silcd/command.c.
1733 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Fixed GETKEY crash, it crashed if the command did not succseed.
1737 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1739 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1740 is now real and not just an macro interface to GMP.
1742 Removed the entire GMP from the source tree and imported new
1743 NSS MPI library instead. Reason for removing GMP is that it is
1744 extremely large and compiles extremely slow. The NSS MPI
1745 is only a few files and compiles in less than 10 seconds.
1746 The speed is also about the same as GMP. The MPI is imported
1747 to lib/silcmath/mpi.
1749 If the system has GMP installed we will still use the GMP.
1750 If it is not then the NSS MPI will be compiled.
1752 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Merged a long nickname (127 characters long) crash bugfix from
1755 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1757 * Merged a freed memory reference bugfix from Irssi CVS tree.
1758 Affected file irssi/src/core/commands.c.
1760 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Added the server's public key sving and verification to the
1763 server when performing the SKE. This was missing and the
1764 remote server's (or router's) public key was accepted without
1765 checking whether we have it previously or trust it at all.
1766 Affected file silcd/protocol.c.
1768 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Check in the silc_server_timeout_remote if protocol is active
1771 and make sure that the protocol's final callback is called so
1772 that all memory if freed. Affected file silcd/server.c.
1774 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * silc_server_whois_send_reply crashed the server if the nickname
1777 was 127 characters long. Affected file silcd/command.c.
1779 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Added sanity check to the silc_server_new_client. If the hostname
1782 is provided inside username then check that the provided hostname
1783 really is the same as the resolved one. If the hostname was not
1784 resolved then check it from the public key. Affected file is
1785 silcd/packet_receive.c.
1787 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1788 if the server disconnected us and the connection is not valid
1789 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1791 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1792 the library to the lib/silcutil/silcutil.[ch].
1794 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1796 * Close log file after open. Affected file
1797 lib/silcutil/silclog.c.
1799 * Check whether sock == NULL in silc_client_send_packet and return
1800 if it is. Affected file lib/silcclient/silcclient.c.
1802 * Check rec->entry == NULL in the Irssi SILC Client before
1803 sending the channel message. Affecte file is
1804 irssi/src/silc/core/silc-servers.c.
1806 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1808 * Merged a splitted window bugfix from Irssi CVS tree. The
1809 affected file is irssi/src/fe-text/textbuffer-view.c.
1811 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1812 It did not print nickname.
1814 * Improved the distributions system a bit.
1816 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1819 irssi/src/fe-text/gui-window.c.
1821 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1822 to in-active server. The affected file is
1823 irssi/src/silc/core/client_ops.c.
1825 * Resolve the client in USERS command reply if the entry does
1826 not have username resolved. The affected file is
1827 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1828 command to WHOIS command to really resolve stuff. The USERS
1829 is not used any more in any critical section so WHOIS can
1830 be used even though it might be slower than IDENTIFY.
1832 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1835 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Changed the protocol API a bit more consistent in the
1838 lib/silccore/silcprotocol.[ch].
1840 * Changed the following headers to ROBODoc format:
1842 lib/silccore/silcpayload.h
1843 lib/silccore/silcprotocol.h
1844 lib/silccore/silcsockconn.h
1846 All core library headers are now formatted.
1848 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Fixed a bug in Irssi SILC client; do not show that you are
1851 server/router operator if you really are not. Affected file is
1852 irssi/src/silc/core/client_ops.c.
1854 * Renamed silc_command_free_payload to silc_command_payload_free.
1855 Affected file lib/silccore/silccommand.h
1857 * Added silcmath.h to include the prototoypes of various routines
1858 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1861 * Changed the following headers to ROBODoc format:
1863 lib/silccore/silcchannel.h
1864 lib/silccore/silccommand.h
1865 lib/silccore/silcid.h
1866 lib/silccore/silcidcache.h
1867 lib/silccore/silcmode.h
1868 lib/silccore/silcnotify.h
1869 lib/silccore/silcpacket.h
1870 lib/silcmath/silcmath.h
1872 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Added checking to the server code not to start the server if
1875 ciphers and stuff are not configured properly. Affected files
1876 silcd/serverconfig.[h] and silcd/server.c.
1878 * Changed the layout of the header files of the public interfaces
1879 in the SILC libraries. The new layout supports ROBODoc
1880 documentation tool (and some others) so that it is easy to create
1881 a library reference manual. All the other headers and source
1882 code must still follow the CodingStyle document. Also source
1883 code must not include these ROBODoc stuffs, only the headers.
1884 Furthermore, all public interface headers must now be named
1885 by using `silc' prefix, example: silcapi.h, silccipher.h.
1886 Some files were renamed due to this. All the other headers
1887 must not be used as public interfaces. I will update the
1888 CodingStyle document later. Changed following headers, so far:
1890 lib/silcclient/silcapi.h
1891 lib/silccore/silcauth.h
1892 lib/silccore/silcprivate.h
1893 lib/silccrypt/silcdh.h
1895 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Removed silc_client_packet_send_flush from the client library
1900 as it is not needed. Affected file lib/silcclient/client.[ch].
1902 * Added printing of message of unresolved authentication method
1903 to the Irssi SILC client. Added it to the module formats.
1904 Removed the same message from the client library.
1906 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Added new distribution feature, DISTLABEL. Every distribution
1909 can define own preprocessor label that can be used in the
1910 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1911 file distributions, acconfig.h.pre and prepare.
1913 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Added Makefile.defines_int to include the actual definitions
1916 for Makefile.defines.in. Tested the new distribution system,
1917 created distributions and tested installation.
1919 * Added AWAY message printing to the Irssi SILC client. Added
1920 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1922 * Added SCONNECT command to call the SILC's CONNECT command.
1923 Cannot use CONNECT directly since Irssi uses that internally.
1924 Affected file irssi/src/silc/core/silc-servers.c.
1926 Added ACTION local command. It is same as ME command but takes
1927 the channel as mandatory argument.
1929 Rewrote some of the Irssi's help files to suite for SILC
1932 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * Added Makefile.defines[.in] that should for now on be included
1935 in all Makefile.am file in the source tree. That file includes
1936 all common compilation definitions for SILC source tree.
1938 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * Minor changes to the ./prepare script to change the package
1941 name according the distribution name to the configure.in.
1943 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Created new distribution system. Added file `distributions'
1946 that defines all the distributions that can be created out of
1947 the SILC source tree. The ./prepare script now reads that
1948 file to determine how to prepare the distributions. The
1949 first argument to the ./prepare is the name of the distribution
1950 and second is the version of the distribution. If given
1951 without arguments it creates the default (toolkit) distribution
1952 with the default version (defined in ./prepare).
1954 All Makefile.am files that are subject to the distributions
1955 are now named as Makefile.am.pre. These are ./Makefile.am
1956 and lib/Makefile.am. Others may be changed later.
1958 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Added invite list, ban list, some key management and connection
1961 error message printing to module formats in the Irssi SILC client.
1963 * Added new silc_client_set_away_message to set the away message
1964 that is back to the person who sent private message. The
1965 affected file lib/silcclient/silcapi.h and the
1966 lib/silcclient/client_prvmsg.c.
1968 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1970 * Fixed the private message sending in the Irssi SILC client,
1971 added local command KEY to the Irssi SILC client.
1973 Added key management and key agreement message formats to the
1974 irssi/src/fe-common/silc/module-formats.[ch].
1976 Added USERS (alias WHO) printing, server/router operator
1977 indication and LIST command printing to the module formats.
1979 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1981 * Fixed channel joining notify handling, cumode notify handling
1982 from Irssi SILC client.
1984 * Added SILC specific module-formats to the Irssi SILC client so
1985 that SILC specific message hilighting, colors etc is possible.
1986 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1988 Added channel mode, channel user mode, actions, notices,
1989 whois and whowas printing to the the module-formats.c.
1991 * Fixed a bug in channel deletion in the server. The channel
1992 is not left to the cache even if the channel founder auth mode
1993 is set when there are no users anymore on the channel. Affected
1994 file silcd/server.c.
1996 * The silc_net_localhost now resolves the entire hostname including
1997 the domain name. Affected file lib/silcutil/silcnet.c.
1999 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Changed the ask_passphrase client operation to be ascynchronous.
2002 It has now a completion callback and a context that the
2003 application must call after it has got the passphrase from
2004 the user. Affected files lib/silcclient/silcapi.h,
2005 lib/silcclient/protocol.c, lib/silcclient/command.c and
2008 Added SilcAskPassphrase callback that the application calls
2009 to deliver the passphrase to the library.
2011 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2012 The public key verification and especially a certificate
2013 verification is asynchronous procedure.
2015 Added new SILC_SKE_STATUS_PENDING status to indicate the
2016 request is pending and a callback will be called to finalize
2019 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2020 indicate that remote end did not send its public key (or
2021 certificate), even though we require it. Added check for this
2022 condition in the SKE. This was a security bug, now fixed.
2024 Defined new SilcSKEVerifyCbCompletion callback that is called
2025 when the verification process is completed.
2027 The affected files lib/silcske/silcske_status.h and
2028 lib/silcske/silcske.[ch].
2030 * Changed the verify_public_key client operation to be async
2031 as well. Defined SilcVerifyPublicKey callback that is used to
2032 indicate the success of the public key verification process.
2034 Changed the server and client to use the new async client
2037 * Changed the Irssi SILC client's internal scheduler to be called
2038 twice as many times as it used to be. As a result the client
2039 should be a bit faster now. Affected file is
2040 irssi/src/silc/core/silc-core.c.
2042 * Added support to Irssi SILC client of asynchronous public key
2043 verification and passphrase inquiry. Affected file is
2044 irssi/src/silc/core/silc-core.c.
2046 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2048 * Do not say "You have left channel %s" in client library.
2049 Moved it to the application. Affected files are
2050 lib/silcclient/command.c and silc/client_ops.c.
2052 * Fixed silc_client_get_clients. Command context was not
2053 duplicated and was freed memory in the callback. Affected
2054 file lib/silcclient/idlist.c.
2056 * Do not say "you are now talking..." on JOIN command in the
2057 client library. The appliation must handle it.
2059 * Do not say ".. changed topic to" in command reply in the
2060 client libary. The application must handle it.
2062 * Fixed TOPIC command sending in the client library.
2064 * Fixed a memory leak in silc_client_command_free in the file
2065 lib/silcclient/command.c.
2067 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Imported a modified version of Irssi client to the source tree.
2070 The Irssi will be used to create a new client called
2071 Irssi SILC. Imported to irssi/.
2073 Added silc_core_init_finish function to the Irssi. Affected
2074 file irssi/configure.in.
2076 A lot changes in the Makefile.ams around the irssi tree.
2078 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Do not rehash if the new size is same as the old size of the
2081 hash table, in the silc_hash_table_rehash*. The affected file
2082 lib/silcutil/silchashtable.c.
2084 * Replaced hash_table_del_by_context calls from the server
2085 (when channel->user_list and client->channels) to the
2086 hash_table_del as it is sufficient and faster.
2088 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2090 * Added silc_hash_table_list, silc_hash_table_get and the
2091 SilcHashTableList structure to provide an alternative way to
2092 traverse the hash table. The affected files are
2093 lib/silcutil/silchashtable.[ch].
2095 * Changed the server's idlist routines to use the hash table
2096 routines to optimize the code.
2098 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Replaced the client entry's `channel' list and channel entry's
2101 `user_list' list to hash tables for optimized lookup. Changed
2102 the code to use the hash table interface around the code.
2103 Affected file lib/silcd/idlist.[ch].
2105 * Added `auto_rehash' boolean argument to the function
2106 silc_hash_table_alloc to indicate whether the hash table should
2107 auto-rehash when it thinks is appropriate time. It will
2108 increase the hash table size if the there is twice as much
2109 entries in the table than the size of the table, and will
2110 decrease the size if there are twice as less entries than
2111 the size of the table.
2113 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2117 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * silc_idcache_purge_by_context deletes the entry now by context
2120 as it is supposed to do. Affected file lib/silccore/idcache.c.
2122 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2123 client is not anymore valid (WHOWAS givens the info) and not
2124 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2126 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2128 * Removed the `data' and `data_len' arguments from the ID Cache
2129 interfaces and added `name' argument. ID Cache does not handle
2130 anymore the binary data only a names associated with given ID.
2132 * When hashing a Client ID with silc_hash_id the entire ID is
2133 not hashed anymore, instead only the hash of the Client ID is
2134 hashed. This way we can access the Client ID from the cache
2135 with Client ID but with the hash of the ID (which is a hash of
2136 the nickname) as well without any difference in performance.
2138 Added also silc_idcache_find_by_id_one_ext to do one on one
2139 searching when we have the actual ID. Added also function
2140 silc_hash_client_id_compare. The affected files are
2141 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2143 * When hashing the name associated with a ID it is always done
2144 in lowercase. This way we can access the cache without worrying
2145 about case-sensitivity, even though, for example nicknames are
2148 * Fixed a bug in server with channel message sending. It put
2149 wrong ID type as destination ID. The affected file
2150 silcd/packet_send.c.
2152 * silc_idcache_del_by_context now deletes from all hash tables
2153 by context. Affected file lib/silccore/idcache.c.
2155 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Changed the client library to use the new ID Cache interface.
2158 Changes around the source tree.
2160 * Added silc_hash_table_rehash_ext to rehash with specific
2161 hash function. Affected file lib/silcutil/silchashtable.[ch].
2163 * Added silc_hash_string_compare to compare two strings in the
2164 hash table. Affected file lib/silcutil/silcutil.[ch].
2166 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2168 * Added new function silc_idcache_del_by_context into the
2169 lib/silccore/idcache.[ch].
2171 * Changed the server's ID list routines to use the new ID Cache
2172 interface. Changes around the source tree.
2174 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2176 * Added silc_hash_table_del[_by_context]_ext functions in to the
2177 lib/silcutil/silchashtable.[ch].
2179 Removed silc_hash_table_find_all* routines and added new
2180 silc_hash_table_find_foreach to replace them.
2182 Added silc_hash_table_replace_ext function as extended
2183 replacing function. Separated the simple hash table interface
2184 from the extended hash table interface in the file
2185 lib/silcutil/silchashtable.h.
2187 * Fixed minor bugs and changed it to use some of the new
2188 hash table functions in lib/silccore/idcache.c
2190 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Added new function silc_hash_table_find_all to return all keys
2193 in the hash table by the specified key. As the hash table is
2194 collision resistant it also makes it possible to have several
2195 duplicate keys in the hash table. This function may be used to
2196 find all of the keys from the hash.
2198 Added user_context arguments to the SilcHashFunction,
2199 SilcHashCompare and SilcHashDestructor to deliver user specified
2202 Added new fuctions silc_hash_table_find[_all]_ext to do
2203 extended lookup with specified hash and compare functions and
2204 specified user contexts.
2206 Added new function silc_hash_table_add_ext to add the key
2207 with specified hash function and user context.
2209 Added new function silc_hash_table_foreach to traverse all
2210 entrys in the hash table. Added SilcHashForeach callback
2213 Added new function silc_hash_table_del_by_context to delete
2214 the entry only if the context associated with the key matches.
2216 Affected files are lib/silcutil/silchashtable.[ch].
2218 * Removed silc_hash_[server/client/channel]_id and added just
2219 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2220 silc_hash_id_compare to compare two ID's using as the hash table
2221 comparison function. Added also silc_hash_data to hash
2222 binary data and silc_hash_data_compare to compare it.
2224 * Removed silc_idlist_find_client_by_hash as it is not needed
2225 anymore. Affected file silcd/idlist.[ch].
2227 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2228 to use internally the SilcHashTable. The new ID Cache is a lot
2229 faster than the old one. Some of the ID Cache interface was also
2230 rewritten and obsolete and stupid functions were removed.
2232 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Added entry_count field to the SilcHashTable to keep the number
2235 of the entries in the table. Implemented the function
2236 silc_hash_table_rehash. Added new function
2237 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2239 Fixed a minor bug in silc_hash_table_free.
2241 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2242 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2243 into the lib/silcutil/silcutil.[ch].
2245 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Implemented a collision resistant hash table into the
2248 lib/silcutil/silchashtable[ch]. See the header and the source
2249 for the SilcHashTable API.
2251 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Merged dotconf version 1.0.2 into lib/dotconf.
2255 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Do not compile anything in lib/silcsim/* if the SIM support
2258 is not enabled. The tree should now compile without problems
2261 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2263 * Compiled the SILC under cygwin. Compiled and tested briefly
2264 without problems. More tests needed. The SIMs didn't compile
2267 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2269 * Fixed possible crash in silc_get_username in the
2270 lib/silcutil/silcutil.c.
2272 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2274 * Fixed a va_arg in silc/client_ops.c.
2276 * Oops, RC5 routines were named AES and caused some problems
2277 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2279 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Added new SilcIDIP structure into the lib/silccore/id.h and
2282 replaced the old `ip' fields from all SILC ID's to that type.
2283 This is a step towards IPv6 support.
2285 The silc_id_get_len takes now the ID as an extra argument.
2286 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2287 both IPv4 and IPv6 based ID's.
2289 The affected files are lib/silccore/id.[ch] and other files
2290 around the tree using these routines.
2292 * Removed the ID length arguments in server from various
2293 silc_server_send_notify_* routines -> they are not needed
2296 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2298 * Fixed memory leak in silc_encode_pem_file in the file
2299 lib/silcutil/silcutil.c.
2301 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Check minor version as well in the SKE. Affected files are
2304 silcd/protocol.c and lib/silcclient/protocol.c.
2306 * Added --identifier option to the server so that an identifier
2307 can be when creating the public key for the server. Affected
2308 file is silcd/silcd.c.
2310 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2311 lib/silccrypt/silcpkcs.c.
2313 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Register default ciphers and stuff when using -C option with
2316 the server. Affected file sildc/silcd.c.
2318 * Put back the servers public key filename format, it is better
2319 than the new one. For now, the client keys are saved with the
2320 new filename format. The affected file silc/client_ops.c.
2322 * Implemented the Cipher API for the rest of the ciphers that
2323 did not implement it or implemented it the wrong way.
2325 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2327 * Register default ciphers and stuff when using the -S option
2328 in the client. Affected file silc/silc.c. Same also when
2329 creating new key pair with -C option.
2331 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2333 * Fixed the silc_verify_public_key client operation function to
2334 save the public keys differently. The fingerprint is now
2335 used as filename and not the hostname. This way also the
2336 client keys are saved uniquely and not with hostnames. The
2337 affected file is silc/client_ops.c.
2339 * Trimmed the silc_hash_fingerprint function to remove extra
2340 whitespaces from the end of the fingerprint. The affected
2341 file is lib/silccrypt/silchash.c.
2345 * Added silc_cipher_register_default function to register all
2346 default ciphers. It can be used when configuration files
2347 does not exist and the application does not want any specific
2348 ciphers in any specific order.
2350 The SilcDList is now used as silc_cipher_list dynamically
2351 allocated cipher list. Removed the static list all together
2352 and now all ciphers must be allocated to the dynamic list.
2353 The silc_cipher_alloc routine was changed to check only the
2356 All silc_cipher_* routines that used to return int returns
2359 The affected files lib/silccrypt/silccrypt.[ch].
2361 * The same thing was done to silc_hash_* as for silc_cipher_*
2362 routines. Affected files lib/silccrypt/silchash.[ch].
2364 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2365 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2366 Added also silc_pkcs_[un]register[_default] functions.
2367 Removed the data_context from the PKCS API.
2369 * Added silc_hmac_register_default function to register default
2370 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2371 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2372 to unregister all hmacs at once.
2374 * Register the default ciphers, hash functions, PKCSs and HMACs
2375 if client's configuration file does not exist. The affected
2378 * The client did not load the hash functions from the SIM
2379 modules at all. Added support for this. Affected file is
2380 silc/clientconfig.c.
2382 * When decoding public key with silc_pkcs_public_key_decode, check
2383 the supported algorithm only if PKCS are registered. Affected
2384 file lib/silccrypt/silcpkcs.c. The same was done with the
2385 silc_pkcs_private_key_decode.
2387 * Fixed the SILC List routines to keep the list always in order.
2388 It used to change the list's order when traversing the list but
2389 not it preserves the order. Affected file lib/trq/silclist.h.
2391 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2393 * Added the client library to use the SilcSocketConnection's
2394 reference counter (by silc_socket_dup) to prevent the bug that
2395 the socket object may be freed underneath async operation.
2397 * The name resolv library checking fixes in the configure.in.pre.
2400 * Created new version of the protocol drafts for future
2401 development. The -03 drafts are the ones that will be changed
2402 in the trunk now and the -02 will remain as they are.
2404 * Send list of CUMODE notifys to the router when announcing
2405 the channel users to the router. Affected file silcd/server.c.
2406 If the router receiving channel founder CUMODE for a channel
2407 that already has channel founder it will send CUMODE notify
2408 to the sender to remove the channel founder rights from the
2409 announced client. Affected file silcd/packet_receive.c.
2411 * The CUMODE notify may now use Server ID as well as the entity
2412 who changes the mode. Updated protocool specs.
2414 * Updated INSTALL and README files.
2416 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * New web pages in the http://silc.pspt.fi. The pages was
2423 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Implemented the [DenyConnectin] config section in the server.
2426 Added silc_server_config_denied_conn to check whether incoming
2427 connection is denied. Affected file silcd/serverconfig.[ch].
2429 * Do not check the ports when checking the incoming configuration
2430 data if the port is 0, meaning any. Affected file is
2431 silcd/serverconfig.c.
2433 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Fixed buffer overflow in silc_string_compare in the file
2436 lib/silcutil/silcutil.c.
2438 * Fixed double free in silc_server_command_leave in the file
2441 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * Fixed the version checking in the server. Affected file is
2446 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Fixed the configuration data fetching when accepting new
2449 connections in the server. Affected file silcd/server.c.
2451 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2453 * Added `sender_entry' argument to the function
2454 silc_server_packet_relay_to_channel so that we can check
2455 whether some destination actually belongs to the same route
2456 the sender belongs (ie, we must not resend the packet to the
2457 sender). Affected file silcd/packet_send.[ch].
2459 * Added `servername' field to the SilcClientEntry in the server
2460 to hold the name of the server where client is from. Affected
2461 file is silcd/idlist.h.
2463 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2465 * Moved the channel message encrypting in the router betwen
2466 router connections from silc_server_channel_message to the
2467 silc_server_packet_relay_to_channel since we want to check
2468 whether we have anybody channel before encrypting anything.
2469 Affected files silcd/packet_[receive/send].c.
2471 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2473 * Fixed the [AdminConnection] server config section to support
2474 multiple entries. Affected file silcd/serverconfig.c.
2476 * Added support into the server to check the validity of the
2477 incoming connection before executing any KE or authentication
2480 * The connection configuration is now saved to the KE and
2481 connection auth protocol contexts and not fetched anymore in
2482 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2484 * The local hosts listenning address and port is also resolved
2485 now when starting the server. We want to have the socket object
2486 to include the real address and port for the listener. Added
2487 new function silc_net_check_local_by_sock into the files
2488 lib/silcutil/silcnet.[ch].
2490 * Fixed a broadcast bug in server -> do not broadcast if we
2493 * Fixed a routing bug. Do not route broadcast packets ever.
2494 Broadcast packets must be processed always and not routed since
2495 they may be destined to some other host than yourself and thus
2496 would get routed without no good reason. Affected file is
2499 * Added function silc_server_config_is_primary_route to check
2500 whether primary router connection has been configured (a router
2501 configuration that we are initiating). If there is not, we
2502 will assume that there is only two routers in the SILC network
2503 and we will use the incoming router connection as our primary
2504 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2506 * Changed the order of the broadcasting. Broadcast _after_ the
2507 packet has been processed not before. Affected file is
2510 * Fixed a [ClientConnection] parsing bug. The port was never
2511 parsed correctly thus resulting to port 0. Affected file
2512 silcd/serverconfig.c.
2514 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2515 argument and did not set the broadcast packet flag. Affected
2516 file silcd/packet_send.c. Fixed same bug in the function
2517 silc_server_send_notify as well.
2519 * If we receive NEW_ID packet for our own ID in the server, ignore
2522 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2526 * Removed the nickname from the Private Message Payload.
2527 Updated the code and the protocol specs.
2529 * Updated protocol specs for submitting to the IETF.
2531 * Tweaked the Random Number Generator a bit. Affected file
2532 lib/silccrypt/silcrng.c. Exported a new function
2533 silc_rng_[global]_add_noise which can be used to add more
2536 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2538 * Do not parse packets with different timeout when protocol
2539 is active -> may cause problem with rekey. Affected file
2542 * When server receives signoff notify it must not create
2543 new channel key if the client is on any channels since the
2544 sender of the signoff notify will create it.
2546 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Added printing of error messages during SKE protocol from the
2549 failure packet sent by server during SKE. Affected file
2552 * Removed the client's failure_callback handling with timeout
2553 and handle it immediately when received.
2555 * The SKE library returned wrong type in SUCCESS and FAILURE
2556 packets. They must be 32 bit MSB not 16 bit MSB.
2558 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2560 * Ok, rewrote the logic of the re-key and now it seems to work.
2561 I tested it on high traffic with frequent re-keys without
2562 problems. Added hmac_receive (and renamed hmac to hmac_send)
2563 in SilcClientConnection in lib/silcclient/client.h and
2564 in SilcIDListData in silcd/idlist.h. Also, removed the
2565 SilcPacketParserContext's cipher and hmac fields as they are
2566 not needed anymore and actually caused some problems when
2567 the ciphers and hmac's changed underneath the packet parser.
2569 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2571 * If re-key protocol is active then process the incoming packets
2572 synchronously since we must assure that icoming packets encrypted
2573 with the old key is processed before the new keys is set to
2574 use. This is true other packets than for REKEY packets.
2575 Affected file silcd/server.c. The same was done to client library
2576 as well, affected file lib/silcclient/client.c.
2578 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2580 * Fixed bug in client and server to accept the force send if
2581 the packet is send from silc_[server/client]_packet_process
2582 function. Otherwise the packets are never delivered, oops.
2584 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Disable force sending of packets when REKEY protocol is active.
2587 We must assure that no packet is sent directly when rekey is
2588 performed. All packets must be sent through packet queue.
2589 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2590 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2591 function is silc_[server/client]_packet_send_real to check
2594 * Replaced the SIM paths from example config files to
2595 /usr/local/modules. Also, make install creates now
2596 /usr/local/silc/logs directory to hold all the SILC server
2599 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Made the configure.in.pre work on Solaris. Patch by salo.
2603 * Made all ciphers compatible with non-x86 machines. Defined
2604 CBC mode macros into lib/silccrypt/ciphers_def.h.
2606 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Fixed the make install.
2610 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * When MAC computation fails the silc_packet_decrypt returned 0
2613 even though it was supposed to return -1. Fixed this. The
2614 affected file is lib/silccore/silcpacket.c.
2616 * Do not replace the config files in /etc/silc (in make install)
2617 if they already exist. Affected file ./Makefile.am.
2619 * Do not send re-key packets immediately but through packet queue.
2620 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2622 * Changed silc_net_check_host_by_sock to return FALSE if the
2623 IP/DNS could not be resolved. Though, it returns the IP address
2624 now even if it could not resolve it (but returns also FALSE).
2625 Affected file lib/silcutil/silcnet.[ch].
2627 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Added silc_pkcs_decode_identifier to decode the public key's
2630 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2631 Added also silc_pkcs_free_identifier. Added also new context
2632 SilcPublicKeyIdentifier.
2634 * Added -S option to the silc client. It is used to dump the
2635 contents of the specified public key file.
2637 * Changed the PKCS api to return the public key length when
2638 setting the public key.
2640 * Fixed a fatal bug in the public and private key file loading.
2641 Affected file lib/silccrypt/silcpkcs.c.
2643 * Execute the packet parsing for client with zero (0) timeout
2644 if the protocol is active. Affected file silcd/server.c.
2646 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Made the key generation options to the silcd program. Added
2649 -C option, equivalent to client's option.
2651 * Added new [ServerKeys] config section to the server. It
2652 configures the server's public and private key.
2654 * Defined generic Public Key Payload into the protocol
2655 specification to send specific type of public keys and
2658 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2659 public key or certificate.
2661 * Implemented the GETKEY command to the server and to the
2662 client library and on user interface.

2670 * Added SilcServerRekey context into silcd/idlist.h.
2672 * Added the PFS support as defined in the specification to the
2673 SKE protocol. Affected files lib/silcske/*.c.
2675 * Added `ske_group' field to the SilcServerRekey context to hold
2676 the number of the SKE group that is used with PFS in re-key.
2677 Affected file silcd/idlist.h.
2679 * Added PFS re-key support to the server. Affected file is
2682 * Added silc_protocol_cancel to cancel execution of the next
2683 state of the protocol. Affected file is
2684 lib/silccore/silcprotocol.[ch].
2686 * Added the re-key support with and without PFS to the client
2687 library. Re-key is performed once in an hour, by default.
2689 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2690 Added silc_client_rekey_callback and silc_client_rekey_final.
2691 Affected files are lib/silcclient/protocol.[ch] and
2692 lib/silcclient/client.[ch].
2694 * Removed the `hmac_key' and `hmac_key_len' fields from the
2695 SilcClientConnection structure; not needed. Affected file is
2696 lib/silcclient/client.h.
2700 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Do not ask whether user wants to use the negotiated private key
2703 for private messages, just use it. Affected file is
2704 silc/local_command.c.
2706 * Added `send_enc_key' and `enc_key_len' fields to the
2707 SilcIDListData structure since they are needed in the re-key
2708 phase. Affected file is silcd/idlist.[ch].
2710 * Implemented the simple re-key protocol into the server.
2711 Affected files silcd/server.c and silcd/protocol.[ch]. The
2712 re-key will be performed once in an hour, by default.
2714 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2715 Added silc_server_rekey, silc_server_rekey_callback and
2716 silc_server_rekey_final.
2718 * Removed Tunneled flag from the protocol. Updated the code
2719 and the specifications.
2721 * Adde `pfs' field to the SilcIDListData to indicate whether
2722 the PFS is to be performed in the re-key. Affected file is
2725 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2727 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2728 int64 of at least the xintXX size. If void * is less that 4
2729 bytes uint32 * will be used. Defined bool as boolean.
2731 * Changed _ALL_ unsigned long and unsigned int to uint32,
2732 unsgined short to uint16 in the source tree.
2734 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2735 not handle clients that has entry->data.registered == FALSE.
2736 They are not in the network anymore. Affected file is
2739 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Implemented the sending of the SERVER_SIGNOFF notify in the
2742 server. Affected file is silcd/server.c.
2744 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2745 Added also silc_notify_payload_encode_args into the
2746 lib/silccore/silcnotify.[ch].
2748 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2749 Affected file silcd/packet_receive.c.
2751 * Implemented the SERVER_SIGNOFF notify handling in the client
2752 library. Affected file lib/silcclient/client_notify.c. Also,
2753 implemnted the printing of the SERVER_SIGNOFF info to the
2754 application. Affected file silc/client_ops.c.
2756 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2757 if the deleting was successful. Affected file silcd/idlist.[ch].
2759 * Added support for public key authentication in the connection
2760 authentication protocol in the client library. Affected file
2761 lib/silcclient/protocol.c.
2763 * Changed the server's silc_idlist_get_clients_by_* interface
2764 to support already allocated array so that new entries may be
2765 added to pre-allocated array. Affected file silcd/idlist.[ch].
2766 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2767 and command replies.
2769 * All command reply functions in the server now calls the
2770 pending command callback even if error occured. This way the
2771 error will be delivered to the client as well. Affected files
2772 silcd/command.c and silcd/command_reply.c.
2774 * Fixed INFO command to return local server's info if no server
2775 was provided. Affected file lib/silcclient/command.c.
2777 * Removed RESTART command for good. Updated the code and the
2780 * Rewrote parts of the task system. It is a bit simpler now.
2781 Removed unsued task priorities. The affected files are
2782 lib/silcutil/silctask.[ch].
2784 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Moved the USERS printing from the library to the application.
2787 Affected files lib/silcclient/command.c and silc/client_ops.c.
2789 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Added channel key re-key support. The re-key is perfomed
2794 only by the router and is done once in an hour. Added `rekey'
2795 field to the SilcChannelEntry in the server. Affected files
2796 silcd/server.c and silcd/idlist.h.
2798 * Added silc_task_unregister_by_context into the file
2799 lib/silcutil/silctask.[ch].
2801 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Added SILC_UMODE_GONE mode to indicate when the client is not
2804 present in the SILC network. Added also support to the local
2805 command AWAY that will set this mode. Added support of showing
2806 "xxx is gone" in WHOIS command. The USERS command shows the
2807 gone status as well.
2809 * Fixed setting server and router operator privileges in the
2810 server's UMODE command. Affected file silcd/command.c.
2812 * Merged the SKE KE1 and KE2 payloads into one payload. The
2813 new KE payload is equivalent to the old KE2 payload.
2815 Cleaned up the SKE Start Payload parsing. It now uses the
2816 simple buffer unformatting to do the parsing. A lot faster
2819 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2820 to the SKE that is used to indicate whether both of the SKE
2821 parties should perform authentication. By default only the
2822 responder performs authentication. By setting this flag also
2823 the initiator must do authentication. By default it is unset
2824 since in normal SKE case, client to server connection, only
2825 the responder should do authentication. When doing SKE between
2826 two clients both should perform authentication. Updated the
2827 code and the protocol specs.
2829 * A little fix to IDENTIFY command in the server. Search the
2830 client first by hash not nickname. Affected file is
2833 * Fixed the silc_client_close_connection to support closing
2834 the client to client connections wihtout deleting too much
2835 data. Affected file lib/silcclient/client.c.
2837 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2838 are received if protocol used to be active but is not anymore
2839 the application would crash due to NULL pointer dereference.
2840 Affected files silcd/server.c and lib/silcclient/client.c.
2842 * Added `hash' field to the SilcClientConnection to include
2843 the hash function negotiated in the SKE protocol.
2845 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2846 to set the channel founder authentication data. A client can
2847 claim the founder rights later by providing the authentication
2848 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2849 This way the channel founder can regain the channel founder
2850 privileges even it is left the channel. This works only on
2851 local server and the client must be connected to the same
2852 server to be able to regain the founder rights. Updated the
2853 protocol specs accordingly.
2855 Added support to the CMODE command in the client to set the
2856 founder auth data. Read the README to see how to set it.
2858 Added support to the CUMODE command to claim the founder
2859 rights. Read the README to see how to do it.
2861 Added support for the founder authentication to the Channel
2862 Entry in the server. Affected file silcd/idlist.h.
2864 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2865 server's CMODE command. Affected file silcd/command.c.
2867 * Added the following new functions into lib/silccore/silcauth.[ch]:
2868 silc_auth_get_method and silc_auth_get_data.
2870 * The server now saves the remote hosts public key to the
2871 SilcIDListData pointer. Affected file silcd/protocol.c.
2873 * The normal server now does not remove the channel entry from
2874 the cache if the founder authentication data is set. It used
2875 to remove it if the founder was the last one on the channel on
2876 the server and left the channel. The auth data is saved and
2877 if the channel is re-joined later the old entry is used with
2878 the old auth data. Affected files silcd/command_reply.c and
2881 * Removed the `pkcs' field from the SilcIDListData structure
2882 in the server; it is not used. Affected file silcd/idlist.h.
2884 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2886 * Fixed packet processing on slow links. Partial packets were
2887 never re-processed because the incoming data buffer was cleared
2888 by the application. Application must not directly clear the
2889 sock->inbuf, the packet processing routines handle it. Fixed
2890 this in client library and in server.
2892 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Fixed the WHOIS and IDENTIFY send reply function to really
2895 check whether to send list or just one entry. Affected file
2898 * Cleaned up the LEAVE command's channel key distribution. The
2899 affected file silcd/command.c.
2901 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2902 can enforce the channel mode as well. In that case the ID
2903 includes the ID of the server. The code now enforces the
2904 mode change if the router have different mode than the server.
2906 * The notify client operation with CMODE_CHANGE notify can now
2907 return NULL client_entry pointer if the CMODE was not changed
2908 by client. Application must check for this.
2910 * Added <Server ID> argument to INFO command to support server
2911 info fetching by Server ID.
2913 * Added silc_server_announce_get_channel_users to get assembled
2914 packets of channel users of the specified channel. Affected
2915 file silcd/server.[ch].
2917 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2918 was freed underneath the ID Cache.
2920 * Re-announce clients when the server received CHANNEL_CHANGE
2921 notify from the router. Affected file silcd/packet_send.c.
2923 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2926 crashed since it did not handle the fact that there is no cipher
2927 called "3" and didn't check the error condition. Now fixed.
2929 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2930 flag. It can be used to send message requests.
2932 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2934 * Implemented the RESTART command in the client.
2936 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2937 notice type messages. Added notice printing to the user
2940 * The channel keys are not re-generated if the channel's mode
2941 is PRIVKEY, ie private key on the channel exists. Affected
2942 files silcd/server.c and silcd/command.c.
2944 * Fixed a little bug in channel message delivery when channel
2945 private keys are set in the server. Affected file is
2946 silcd/packet_send.c.
2948 * Changed the setting on channel->on_channel = TRUE from the
2949 silc_client_save_channel_key to the JOIN command reply. The
2950 key payload is not received if the private channel key is set.
2951 Affected file lib/silcclient/command_reply.c and the
2952 lib/silcclient/client_channel.c.
2954 * When the CMODE_CHANGE notify is sent and the channel private
2955 key mode is removed the channel key must be re-generated in
2956 other cells as well. Added this support for the router in the
2957 silcd/packet_receive.c.
2959 * Added new local command NOTICE to send notice message on
2960 channel. Affected file silc/local_command.[ch].
2962 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2964 * Added new local command ME to the client. It is used to send
2965 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2966 some action. Affected file silc/local_command.[ch].
2968 * Changed channel_message and private_message client operations
2969 to deliver the message flags to the application. Added also
2970 the `flags' arguments to the silc_client_send_channel_message
2971 and silc_client_send_private_message functions. Affected file
2974 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2976 * Redefined the Private Message Payload to support private message
2977 keys and to support the new private message flags. Updated
2978 the protocol specs. Flags makes it possible to have for example
2979 CTCP style messages.
2981 * Added new type SilcPrivateMessagePayload and defined an API
2982 for it in the lib/silcclient/silcprivate.[ch].
2984 * Tested private message private keys successfully. Tested the
2985 private message key set, unset and list commands with the new
2988 * Redefined the Channel Message Payload to include the channel
2989 message flags (equal with private message flags) to support
2990 for example CTCP style messages.
2992 * Defined some of the message (for channel and private message)
2993 flags. Updated the protocol specs and added the flags to the
2994 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2996 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added SilcKeyAgreementStatus type to the key agreement routines
2999 to indicate the current status and error if one occured.
3000 The status types are defined in the lib/silcclient/silcapi.h.
3002 * Added new local command KEY that is used to set and unset private
3003 keys for channels, set and unset private keys for private messages
3004 with remote clients and to send key agreement requests and
3005 negotiate the key agreement protocol with remote client. The
3006 key agreement is supported only to negotiate private message keys,
3007 it currently cannot be used to negotiate private keys for channels,
3008 as it is not convenient for that purpose.
3010 * Fixed a minor pending callback setting bug in the function
3011 silc_client_get_client_by_id_resolve, now the function works.
3012 Affected file lib/silcclient/idlist.c.
3014 * Added function silc_net_get_local_port to get local bound
3015 port by socket. Added to lib/silcutil/silcnet.[ch].
3017 * Added `sockets' and `sockets_count' fields to the SilcClient
3018 object. They hold the sockets of the listenning sockets in
3019 the client. Listenning sockets may be for example the key
3020 agreement server. Affected file lib/silcclient/client.[ch].
3021 Added functions the silc_client_add_socket and the
3022 silc_client_del_socket. They are exported to the application
3025 * Added ~./silc/clientkeys to support other client's public keys.
3027 * Renamed verify_server_key client operation to verify_public_key
3028 and added one argument to indicate the type of the connection
3029 (server, client etc.).
3031 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3033 * Added silc_server_connection_auth_request to handle the
3034 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3035 silcd/packet_receive.[ch].
3037 * Added silc_server_send_connection_auth_request into the
3038 silcd/packet_send.c to send the connection auth request packet.
3040 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3043 * Fixed the public key authentication in responder side in the
3044 server. The `auth_data' pointer includes the SilcPublicKey
3045 not the path to the public key. Affected file silcd/protocol.c.
3047 * Implemented the public key authentication in the initiator side
3048 in the server. Affected file silcd/protocol.c.
3050 * Removed the [RedirectClient] config section from the server
3051 configuration. Is not needed and I don't want to implement it.
3053 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Cleaned up the CMODE command in the server. It now works
3056 correctly and supports all the modes defined in the protocol.
3057 Affected file is silcd/command.c.
3059 * Added `hmac_name' field to the SilcChannelEntry in the server
3060 to hold the default HMAC of the channel. It can be set when
3061 creating the channel (with JOIN command). Affected files
3064 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3065 type to indicate the change of the current cipher and hmac
3066 on the channel. Client can safely ignore the <cipher> argument
3067 (if it chooses to do so) since the CHANNEL_KEY packet will
3068 force the channel key change anyway. The <hmac> argument is
3069 important since the client is responsible of setting the new
3070 HMAC and the hmac key into use.
3072 * Fixed the CMODE command in the client library as well.
3074 * Tested CMODE command in router environment successfully.
3076 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3078 * Show the version of the remote client (or server) when connecting
3079 to the server. It is logged to the log file. Affected file
3080 is silcd/protocol.c.
3082 * Fixed the KILLED notify handling in the client library. The
3083 client must be removed from all channels when receiving the
3086 Also, do not remove the client entry when giving the KILL
3087 command but when the KILLED notify is received.
3089 * Removed silc_idlist_find_client_by_nickname from the server.
3090 Not needed anymore. Affected files silcd/idlist.[ch].
3092 * Implemented the CHANNEL_CHANGE notify type handling to the
3093 server. Affected file silcd/server.c.
3097 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3099 * Added silc_server_send_notify_invite to send the INVITE
3100 notify between routers.
3102 * Implemented the INVITE command correctly to the server.
3104 * Implemented the INVITE notify type handling in the server.
3106 * Implemented the INVITE command to the client library and on the
3109 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3111 * Added function silc_server_get_client_resolve to find the
3112 client entry by ID from all ID lists and then resolve it
3113 (using WHOIS) if it cannot be found. Affected file is
3116 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Implemented the BAN command to the client library.
3120 * The JOIN command in the server now checks the invite list
3123 * Changed the silc_command_reply_payload_encode_va and the
3124 silc_command_payload_encode_va to support that if argument is
3125 NULL it ignores and checks the next argument. Affected file
3126 lib/silccore/silccommand.c.
3128 * Added silc_server_send_notify_ban to send the BAN notify
3129 type between routers.
3131 * Chaned the silc_notify_payload_encode to support that if
3132 argument is NULL it ignores and checks the next argument.
3133 Affected file lib/silccore/silcnotify.c.
3135 * Tested ban lists in router environment successfully.
3137 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Implemented BAN command to the server, in silcd/command.[ch].
3141 * Removed the BAN and INVITE_LIST modes from the CMODE command
3144 * Added function silc_string_match to regex match two strings.
3145 Affected files lib/silcutil/silcutil.[ch].
3147 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3149 * Redefined parts of the SilcChannelEntry in the server to support
3150 the new ban and invite lists.
3152 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Redefined the INVITE command. The same command can be used to
3155 invite individuals to the channel but also to manage the invite
3156 list of the channel (to add to and remove from the invite list).
3157 Updated the protocol specs.
3159 * Added new command SILC_COMMAND_BAN that can be used to manage
3160 the ban list of the channel. Updated the protocol specs.
3162 * Removed the channel modes: the SILC_CMODE_BAN and the
3163 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3164 in the CMODE command. The equivalent features are now available
3165 using INVITE and BAN commands. Updated the protocol specs.
3167 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3168 in the network about change in the current ban list. The notify
3169 type is not used by the client.
3171 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3172 support the invite lists.
3174 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Added new function silc_string_regexify that converts string
3177 including wildcard characters into regex string that can
3178 be used by the GNU regex library. Added into the file
3179 lib/silcutil/silcutil.[ch].
3181 Added silc_string_regex_combine to combine to regex strings
3182 into one so that they can be used as one regex string by
3183 the GNU regex library. Added into the file
3184 lib/silcutil/silcutil.[ch].
3186 Added silc_string_regex_match to match two strings. It returns
3187 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3189 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3191 * Imported GNU regex to the soruce tree into lib/contrib.
3192 Fixed some compiler warning from the regex.c.
3194 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3196 * Fixed MOTD command in the server to work in router environment.
3198 * Fixed the MOTD command in the client library to support
3199 the server argument in the command.
3201 * Added `nickname_len' argument to the silc_idlist_add_client
3202 in the server, as the `nickname' argument may be binary data
3205 * Added silc_idlist_get_channels to return all channels from
3208 * Implemented LIST command to the server. Affected file is
3211 * Implemented the LIST command to the client library and on the
3214 * Added [<user count>] argument to the LIST command reply.
3215 With private channels the user count is not shown.
3217 * Updated TODO and README.
3219 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3221 * The client entry's data.registered must be TRUE even with
3222 global client entry on global client list. The data.registered
3223 is used to check whether the client is anymore in the network,
3224 for example with WHOWAS command so it must be valid.
3226 * Fixed the WHOWAS command in the server. It now actually works
3227 in router environment. Added function into silcd/command_reply.c
3228 silc_server_command_reply_whowas_save.
3230 * Added silc_idlist_purge function to the silcd/idlist.c
3231 to periodically purge the ID Cache.
3233 * Fixed INFO command in the server. It works now in router
3234 environment. Added <server name> argument to the INFO command
3235 reply. Updated the protocol specs.
3237 * Fixed minor bug in silc_idcache_purge to not purge if the
3238 expire value is zero.
3240 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3241 they were buggy because of the WHOWAS information.
3243 * Fixed local command MSG to handle the async resolving of
3244 the remote client properly. It used to fail the first MSG.
3245 Affected file silc/local_command.c.
3247 * Added `data_len' field to SilcIDCache context.
3249 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3251 * Update TODO. Todo in commands in the server.
3253 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3255 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3256 used by routers as broadcast packet to inform other routers
3257 about the changed user mode.
3259 Implemented the notify handling in the server. Affected file is
3260 silcd/packet_receive.c. Added the function
3261 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3263 * Added new generic Channel Payload and deprecated the New Channel
3264 Payload. The New Channel Payload is now the generic Channel
3267 * Added new argument `mode' to the silc_server_send_new_channel
3268 as it is required in the Channel Payload now.
3270 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3271 and created a new and real SilChannelPayload to represent the
3272 new generic Channel Payload. Implemented the encode/decode
3273 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3275 * Added silc_server_get_client_channel_list to return the list
3276 of channels the client has joined for WHOIS command reply.
3277 Affected file silcd/server.[ch].
3279 * Implemented the channel list sending in the WHOIS command reply
3280 in server and in the client.
3282 Implemented the channel list displaying on the user interface
3283 as well. Affected file silc/client_ops.c.
3285 * Added silc_channel_payload_parse_list to parse list of Channel
3286 Payloads. It returns SilcDList list of SilcChannelPayloads.
3287 Client for example can use this function to parse the list of
3288 channels it receives in the WHOIS command reply. The caller
3289 must free the list by calling silc_channel_payload_list_free.
3290 Affected files lib/silccore/silcchannel.[ch].
3292 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Added one new argument <user mode> to the WHOIS command reply
3295 to return the mode of the user in SILC. Updated the protocol
3298 Implemented it to the server and client.
3300 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Fixed the mode printing on the user interface on joining.
3303 Affected file silc/client_ops.c.
3305 * Implemented the UMODE command and user modes in general to the
3306 client library and to the user interface.
3308 * Implemented the UMODE command to the server.
3310 * The server now sends UNKNOWN_COMMAND error status if client sends
3311 unknown command. Affected file silcd/command.c.
3313 * All server commands now handle the command identifier the right
3314 way when sending the command reply to the client. The client can
3315 use to identify the command replies with the identifier.
3317 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Added silc_server_get_client_route to resolve the route to
3320 the client indicated by the client ID. Affected file is
3323 * Added silc_server_relay_packet as general function to relay
3324 packet to arbitrary destination. This deprecates functions
3325 like _send_private_message_key, _relay_notify etc. Affected
3326 file is silcd/packet_send.[ch].
3328 Removed silc_server_send_key_agreement,
3329 silc_server_send_private_message_key and
3330 silc_server_packet_relay_notify functions from the file
3331 silcd/packet_send.[ch].
3335 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3336 server. Affected file silcd/packet_receive.[ch].
3338 * Implemented the KILL command to the client. Implemented the
3339 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3340 Affected files lib/silcclient/command[_reply].c and
3341 lib/silcclient/client_notify.c. Implemented the KILL notify
3342 printing in the user inteface.
3344 * Fixed a lot silc_parse_nick memory leaks from the client
3345 library in the file lib/silcclient/command.c.
3347 * Changed the silc_server_send_notify_on_channels's `sender'
3348 argument from SilcSocketConnection to SilcClientEntry to
3349 check the sender as entry and not as connection object and not
3350 to send to the client provided as argument. The affected file
3351 is silcd/packet_send.[ch].
3353 * The notify packets that are destined directly to the client used
3354 to not to be processed by the server. Now changed that and the
3355 server processes all notify packets. After relaying the packet
3356 to the client the notify packet is processed in the server.
3358 * The silc_server_free_client_data now checks whether there is
3359 pending outgoing traffic for the client and purges the data to
3360 the network before removing the client entry.
3362 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3364 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3365 an client is killed from the SILC Network. Updated the protocol
3368 Added new function silc_server_send_notify_killed to the
3369 silcd/packet_send.[ch].
3371 * Added function silc_server_packet_relay_notify to relay notify
3372 packets that are destined directly to a client. In this case
3373 the server does not process the notify packets but merely relays
3374 it to the client. Affected file silcd/packet_send.[ch].
3376 Added also silc_server_packet_process_relay_notify to check
3377 whereto relay the notify. Affected file is
3378 silcd/packet_receive.[ch].
3380 * Implemented the KILL command to the server.
3384 * Added the backup schema desgined last fall to the protocol
3385 specs for everyone to see. The specification is in the
3386 *-spec-xx.txt draft and the packet type definitions for the
3387 backup routers is in *-pp-xx.txt draft. Thusly, added also
3388 new packet type SILC_PACKET_CELL_ROUTERS.
3390 * A big security problem in the implementation discovered. The
3391 signoff of an client did not cause new channel key generation
3392 which it of course should've done. The channel keys must be
3393 always re-generated when client leaves (or signoffs) the channel.
3394 The silc_server_remove_from_channels funtion now handles
3395 the channel key re-generation.
3397 * Added `sender' argument to the silc_server_send_notify_on_channels
3398 to not to send the client provided as argument. Affected file
3399 silcd/packet_send.[ch].
3401 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3403 * Implemented OPER and SILCOPER commands into the server and
3406 * Added silc_auth_verify and silc_auth_verify_data to verify
3407 the authentication directly from the authentication payload.
3408 It supports verifying both passphrase and public key based
3409 authentication. Affected file lib/silccore/silcauth.[ch].
3411 * Added `hash' field to the SilcIDListData structure. It is the
3412 hash negotiated in the SKE protocol. Affected file is
3415 * Slight redesigning of the SilcAuthPayload handling routines.
3416 Do not send SilcPKCS but SilcPublicKey as argument.
3418 * Implemented the public key authentication support to the
3419 serverconfig. The public key is loaded from the provided path
3420 and saved as authentication data to void * pointer. Thus,
3421 changed the unsigned char *auth_data to void *auth_data;
3423 * Fixed SHUTDOWN command to send the reply before the server
3424 is shutdown. :) Affected file silcd/command.c.
3426 * Fixed fatal bug in CONNECT command. The hostname was invalid
3427 memory and server crashed. Affected file silcd/command.c.
3429 * Fixed fatal bug in CLOSE command. The server_entry became
3430 invalid but was referenced later in the command. Affected file
3433 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3435 * Fixed fatal bug in failure packet handling. Server ignored
3436 the failure and thus crashed when it came.
3440 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3443 that the command may be executed only once in (about) 2 seconds.
3444 The old SILC_CF_LAG flag is same but allows command bursts up
3445 to five before limiting.
3447 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3448 server code. Various commands now includes the CF_LAG_STRICT
3449 flag to disallow any kind of miss-use of the command.
3451 * Fixed the silc_buffer_unformat to not to allocate any data
3452 if the length of the data is zero. It used to allocate the
3453 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3455 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Changed the format of AdminConnection configuration section
3458 in the server. Added username of the admin to the format.
3459 Affected files silcd/serverconfig.[ch].
3461 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3462 to return admin configuration data by host, username and/or
3465 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Implemented WHOWAS command to the server. Added the functions:
3469 silc_server_command_whowas_parse,
3470 silc_server_command_whowas_send_reply,
3471 silc_server_command_whowas_from_client and
3472 silc_server_command_whowas_from_server
3474 * Added <Client ID> argument to the WHOWAS command reply. Updated
3475 the protocol specs accordingly.
3477 * Implemented WHOWAS command and command_reply to the client
3480 Implemented the WHOWAS printing on the user interface.
3482 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Added new argument to the WHOWAS command reply, the real name.
3485 It is an optional argument. Updated the protocol specs.
3487 * Added SilcIDCacheDestructor callback that is registered when
3488 the SilcIDCache is allocated. The callback is called when
3489 an cache entry in the ID Cache expires, or is purged from the
3490 cache. Added into lib/silccore/idcache.[ch].
3492 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3493 to destruct the client entries when the cache entry expires.
3494 Other ID Cache's in server and in the client library ignores
3497 * If the ID Cache entry's `expire' field is zero then the entry
3498 never expires. Added boolean `expire' argument to the
3499 silc_idcache_add function in the lib/silccore/idcache.[ch].
3500 If it is TRUE the default expiry value is used.
3502 * Added silc_server_free_client_data_timeout that is registered
3503 when client disconnects. By default for 5 minutes we preserve
3504 the client entry for history - for WHOWAS command.
3506 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3508 * Added support to the server to enforce that commands are not
3509 executed more than once in 2 seconds. If server receives
3510 commands from client more frequently, timeout is registered
3511 to process the commands. Affected file silcd/command.c.
3512 Added new function silc_server_command_process_timeout.
3514 * Changed NICK_NOTIFY handling in client library to check that
3515 if the client's nickname was changed, so there is no need to
3516 resolve anything from the server.
3518 * Removed error printing from the WHOIS and IDENTIFY commands.
3519 If error occurs then it is ignored silently in the client library.
3520 The application, however, may map the received error to
3521 human readable error string. The application currently maps
3522 the NO_SUCH_NICKNAME error to string.
3524 * Made the command status message public to the application. Moved
3525 them from lib/silcclient/command_reply.c to
3526 lib/silcclient/command_reply.h. The application can map the
3527 received command status to the string with the
3528 silc_client_command_status_message function.
3530 * Added check to the server to check that client's ID is same
3531 as the Source ID in the packet the client sent. They must
3534 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * Added dist-bzip hook to the Makefile.am to make bzip2
3537 compressed distributions.
3539 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Server now enforces the maximum length for the nickname and
3542 the channel as protocol specification dictates. 128 bytes for
3543 nickname and 256 bytes for channel name.
3545 * Moved the WHOIS printing to the application. The client libary
3546 does not print out the WHOIS information anymore, the application
3547 must do it. Renamed silc_client_command_reply_whois_print to
3548 the silc_client_command_reply_whois_save.
3550 The client's idle time is also sent to the application now, and
3551 the idle is shown on screen.
3553 * Added silc_client_command_reply_identify_save to save the
3554 received IDENTIFY entries.
3556 * Do not check for channel private keys in message sending and
3557 reception if the channel does not have the PRIVKEY mode set.
3558 Affected file lib/silclient/client_channel.c.
3560 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3562 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3563 just surfaced after chaning the JOIN procedure.
3565 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Added silc_client_get_clients_by_list to get client entries
3568 from Client ID list, that is returned for example by JOIN
3569 and USERS command replies. The application should use this
3570 function for example when JOIN command reply is received to
3571 resolve the clients already on the channel (library does not
3572 do that anymore as USERS command reply is not used in the JOIN
3573 procedure anymore). Affected files lib/silcclient/silcapi.h and
3574 lib/silcclient/idlist.c.
3576 * JOIN command reply and USERS command reply returns now SilcBuffer
3577 pointers instead of unsigned char pointers when returning
3578 the client list and mode list.
3580 * Added <Client ID> argument to the JOIN command reply, mainly
3581 for the server to identify for which client the command was
3582 originally sent. Updated protocol specs accordingly.
3584 * Added SilcDlist private_key pointer to the SilcChannelEntry
3585 in the client to support the channel private keys. Affected
3586 file is lib/silcclient/idlist.h.
3588 * Added SilcChannelPrivateKey argument to the function
3589 silc_client_send_channel_message so that application can choose
3590 to use specific private ke if it wants to. If it is not provided,
3591 the normal channel key is used, unless private keys are set.
3592 In this case the first (key that was added first) is used
3593 as the encryption key.
3595 * Implemented the support for channel private key handling.
3596 Implemented the following functions:
3598 silc_client_add_channel_private_key,
3599 silc_client_del_channel_private_keys,
3600 silc_client_del_channel_private_key,
3601 silc_client_list_channel_private_keys and
3602 silc_client_free_channel_private_keys
3604 Affected file lib/silcclient/client_channel.c.
3606 * Added the support for the private keys in the channel message
3607 sending and encryption and in the message reception and
3608 decryption. Affected funtions are
3609 silc_client_send_channel_message and silc_client_channel_message.
3611 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3613 * Added SKE's key verify callback to the client library's
3614 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3616 * Removed the statement that server (or router) must send USERS
3617 command reply when joining to the channel so that the client
3618 knows who are on the channel. Instead, the client list and
3619 client's mode list is now sent in the JOIN command reply to the
3620 client who joined channel. This is better solution.
3622 * Added function silc_server_get_users_on_channel and function
3623 silc_server_save_users_on_channel to the silcd/server.[ch].
3625 * Removed function silc_server_command_send_users from the
3628 * Do not show topic on the client library anymore. The topic is
3629 sent in the command reply notify to the application and the
3630 application must show the topic now.
3632 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Added client searching by nickname hash into the IDENTIFY and
3635 WHOIS commands in the server as they were clearly missing from
3636 them. Affected file is silcd/command.c.
3638 * Fixed a bug in private message receiving in the client library.
3639 The remote ID was freed and it wasn't supposed, now it is
3642 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Minor fix to the channel payload; allocate the data area, as it
3645 needs to be of specific length.
3647 * If the key agreement port is zero then the operating
3648 system will define the bound port. Affected files are
3649 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3651 * Added new function silc_channel_payload_decrypt into the file
3652 lib/silccore/silcchannel.[ch].
3654 * Moved the channel message etc, check from silc_packet_decrypt
3655 to applications. The library calls now a generic
3656 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3657 when the packet is either normal or special. This was done to
3658 allow more wide range of checking that was not allowed when
3659 the code was in library. Now applications can do virtually any
3660 checks to the packet and return to the library the decision how
3661 the packet should be processed. Affected files are
3662 lib/silccore/silcpacket.[ch].
3664 Added silc_server_packet_decrypt_check to the server and
3665 silc_client_packet_decrypt_check to the client library.
3667 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3668 to send with specified source and destination information.
3670 * Channel message delivery between routers was broken after the
3671 channel key distribution was fixed earlier. The channel key
3672 was used be to distributed to other routers as well which is not
3673 allowed by the protocol. Now this is fixed and channel keys
3674 really are cell specific and the channel message delivery between
3675 routers comply with the protocol specification.
3677 * Fixed various commands in server to check also the global list
3678 for the channel entry and not just the local list. The affected
3679 file silcd/command.c.
3681 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Added assert()s to buffer formatting and unformatting routines
3684 to assert (if --enable-debug) when error occurs. Affected
3685 file: lib/silcutil/silcbuffmt.c.
3687 * Changed to auto-reconnect to check whether the remote host is
3688 router and register the re-connect timeout if it is. It used
3689 to check that whether we are normal server, but router must do
3690 auto-reconnect with another router as well. Affected file
3693 * Removed the [<key len>] option from CMODE command as the cipher
3694 name decides the key length, nowadays. See the defined ciphers
3695 from the protocol specification.
3697 * Added [<hmac>] option to the CMODE command to define the HMAC
3698 for the channel. Added SILC_CMODE_HMAC channel mode.
3700 * Added [<hmac>] option for the JOIN command so that user can
3701 select which HMAC is used to compute the MACs of the channel
3704 * Added Hmac field to the Channel Message Payload. The integrity
3705 of plaintext channel messages are now protected by computing
3706 MAC of the message and attaching the MAC to the payload. The
3707 MAC is encrypted. Now, it is clear that this causes some
3708 overhead to the size of the packet but rationale for this is that
3709 now the receiver can verify whether the channel message decrypted
3710 correctly and also when private keys are set for the channel the
3711 receiver can decrypt the packet with several keys and check from
3712 the MAC which key decrypted the message correctly.
3714 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3715 lib/silccrypt/silccipher.[ch].
3717 * Added silc_hash_len to return the digest length into the
3718 lib/silcrypt/silchash.[ch].
3720 * Rewrote parts of Silc Channel Payload interface in the
3721 lib/silccore/silcchannel.[ch]. The encode function now also
3722 encrypts the packet and parse function decrypts it.
3724 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Fixed a minor formatting bug in the SKE's key material processing.
3727 It actually might have processed the keys wrong way resulting
3730 * Redefined the mandatory HMAC algorithms and added new algorithms.
3731 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3732 and hmac-md5 truncated to 96 bits. The mandatory is now
3733 hmac-sha1-96. Rest are optional (including the one that used
3734 to be mandatory). Rationale for this is that the truncated HMAC
3735 length is sufficient from security point of view and can actually
3736 make the attack against the HMAC harder. Also, the truncated
3737 HMAC causes less overhead to the packets. See the RFC2104 for
3740 * Added new [hmac] configuration section. The SKE used to use
3741 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3742 is of course wrong. The official names that must be proposed in
3743 the SKE are the ones defined in the protocol specification
3744 (hmac-sha1-96 for example). The user can configure any hmac
3745 using any hash function configured in the [hash] section. At
3746 least, the mandatory must be configured.
3748 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3750 * Added HMAC list to the SKE proposal list. It has now both
3751 hash algorithm list and HMAC list. This makes the protocol
3752 incompatible with previous versions. The SKE now seems to work
3753 the way it is supposed to work, for the first time actually.
3755 * Defined plain Hash algorithms to the protocol specification.
3758 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Implemented support for key agreement packets into the server.
3761 Added functions silc_server_key_agreement and
3762 silc_server_send_key_agreement. Other than these functions,
3763 server has nothing to do with this packet.
3765 * Added support for private message key packets into the server.
3766 Added functions silc_server_private_message_key and
3767 silc_server_send_private_message_key.
3771 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3772 called in the protocol's final callback instead in the END
3773 protocol state. This makes a little more sense and in the same
3774 time in client we can use the same protocol routines for normal
3775 key exchange and to key agreement packet handling as well.
3777 * Added to both client's and server's KE protocol context the
3778 SilcSKEKeyMaterial pointer to save the key material. We will
3779 bring the key material to the protocol's final callback by doing
3780 this. The final callback must free the key material.
3782 * Added SKE's packet_send callback into client's KE protocol
3783 context so that the caller can choose what packet sending function
3784 is used. This way we can use different packet sending when
3785 doing normal SKE when doing key agreement packet handling (in
3786 the key agreement packet handling we do not want to encrypt
3789 * Implemented the responder side of the key agreement routines
3790 in the client. The client can now bind to specified port and
3791 accept incoming key negotiation. The key material is passed
3792 to the application after the protocol is over.
3794 * Implemented the processing of incoming Key Agreement packet
3795 in the client. Added function silc_client_key_agreement to
3798 * Implemented the intiator side of the key agreement routines
3799 in the client. The client can now initiate key agreement with
3800 another remote client. The key material is passed to the
3801 application after the protocol is over.
3803 * Created client_keyagr.c to include all the key agreement
3806 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3807 SILC_TASK_CALLBACK except that it is not static.
3809 * Created client_notify.c and moved the Notify packet handling
3810 from the client.[ch] into that file.
3812 * Created client_prvmsg.c and moved all private message and
3813 private message key routines from the client.[ch] into that file.
3815 * Create client_channel.c and moved all channel message and
3816 channel private key routines from the client.[ch] into that file.
3818 * Changed silc_client_get_client_by_id_resolve to resolve with
3819 WHOIS command instead of IDENTIFY command, in the file
3820 lib/silclient/idlist.c.
3822 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3824 * Implemented the SKE's responder side to the Client library.
3826 * When FAILURE is received to the protocol do not trust it
3827 blindly. Register a timeout to wait whether the remote closes
3828 the connection as it should do it, only after that process the
3829 actual failure. This was changed to both client and server.
3831 * Added client_internal.h to include some of the structures
3832 there instead of client.h in lib/silcclient/.
3834 * Added function silc_task_unregister_by_callback to unregister
3835 timeouts by the callback function.
3837 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3839 * Some "Incomplete WHOIS info" errors has been appearing on the
3840 log files. Took away the entry->userinfo check from WHOIS
3841 reply sending. The entry->userinfo is now " " if client did not
3842 provide one. I thought this was fixed earlier but something
3843 is wrong still. Let's see if the error still appears.
3845 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed a minor bug in the login when the channel key is
3848 re-generated in the server. It used to generate the key in
3849 wrong order and thus caused problems in the channel traffic.
3851 * Fixed a minor bug in channel key distsribution after
3852 KICK command. The key was not sent to the router even though
3855 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3857 * Added silc_ske_process_key_material_data as generic routine
3858 to process any key material as the SILC protocol dictates. The
3859 function is used by the actual SKE library but can be used by
3860 applications as well. This relates to the private message keys
3861 and the channel private keys since they must be processed the
3862 same way the normal SILC session keys. The protocol dictates
3863 this. Affected files: lib/silcske/silcske.[ch].
3865 Added also silc_ske_free_key_material to free the
3866 SilcSKEKeyMaterial structure.
3868 * Defined silc_cipher_set_key function to set the key for
3869 cipher without using the object's method function. The affected
3870 files: lib/silccrypt/silccipher.[ch].
3872 * Implemented silc silc_client_add_private_message_key,
3873 silc_client_add_private_message_key_ske,
3874 silc_client_del_private_message_key,
3875 silc_client_list_private_message_keys and
3876 silc_client_free_private_message_keys functions in the
3879 Added functions silc_client_send_private_message_key to send
3880 the Private Message Key payload and silc_client_private_message_key
3881 to handle incoming Private Message Key payload.
3883 * Added Cipher field to the Private Message Key payload to set
3884 the cipher to be used. If ignored, the default cipher defined
3885 in the SILC protocol (aes-256-cbc) is used.
3887 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3889 * Removed lib/silcclient/ops.h file.
3891 Redefined parts of the SILC Client Library API. Created new
3892 file silcapi.h that deprecates the ops.h file and defines the
3893 published Client Library API. Defined also private message key
3894 API and channel private key API into the file.
3896 This is the file that the application must include from the
3897 SILC Client Library. Other files need not be included by
3898 the application anymore.
3900 * Added new key_agreement client operation callback and also
3901 defined the Key Agreement library API for the application.
3903 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3906 is used by clients to request key negotiation between another
3907 client in the SILC network. If the negotiation is started it
3908 is performed using the SKE protocol. The result of the
3909 negotiation, the secret key material, can be used for example
3910 as private message key.
3912 Implemented the Key Agreement payload into the files
3913 lib/silccore/silauth.[ch].
3915 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Redefined ciphers for the SILC protocol. Added some new ciphers
3918 and defined the key lengths for the algorithms. Changed the
3919 code accordingly. The default key length is now 256 bits.
3921 * Fixed SKE key distribution function silc_ske_process_key_material
3922 when the key length is more than 128 bits. The default key
3923 length in SILC is now 256 bits.
3925 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3926 to indicate unsupported algorithm.
3928 * Renamed rijndael.c to aes.c and all functions as well.
3930 * Fixed a long standing channel key setting bug in client library.
3931 Weird that it has never surfaced before.
3933 * Fixed bug in channel deletion. If the entire channel is removed
3934 then it must also delete the references of the channel entry
3935 from the client's channel list as the client's channel entry and
3936 the channel's client entry share same memory.
3938 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Implemented CONNECT and SHUTDOWN commands in the client.
3942 * Implemented CLOSE command to the client.
3944 * Added the function silc_idlist_find_server_by_name into the
3945 files silcd/idlist.[ch].
3947 Added the function silc_idlist_find_server_by_conn into the
3948 files silcd/idlist.[ch].
3950 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3952 * DIE command was renamed to SHUTDOWN. Updated the both code
3955 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3956 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3958 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3961 * Added function silc_server_create_connection function to create
3962 connection to remote router. My server implementation actually
3963 does not allow router to connect to normal server (it expects
3964 that normal server always initiates the connection to the router)
3965 so the CONNECT command is only good for connecting to another
3968 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3971 or some other client was kicked from the channel.
3973 Implemented the handling of the notify type to both client
3976 Implemented silc_server_send_notify_kicked to send the KICKED
3977 notify. It is used to send it to the server's primary router.
3979 * Implemented the KICK command into server and client.
3981 * Added `query' argument to the silc_idlist_get_client function
3982 to indicate whether to query the client from server or not if
3985 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3986 to indicate that the client is not channel founder.
3990 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3992 * Removed the rng context from SilcPacketContext structure and
3993 changed that the packet routine uses the Global RNG API.
3995 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added support for quit message that client can "leave" on the
3998 channel when it quits the SILC. It is ditributed inside the
3999 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4001 Added silc_server_free_client_data that will take the
4002 signoff message as argument.
4004 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4006 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Updated parts of the protocol specification to keep it up
4011 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4014 payloads in one packet.
4016 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4017 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4018 use now the new List flag.
4020 * Also deprecated the following packet types: REPLACE_ID,
4021 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4023 * Added list support for Notify packet in server.
4025 * Added silc_server_send_notify_channel_change to send the
4026 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4027 the silc_server_send_replace_id.
4029 * Added silc_server_send_notify_nick_change to send the
4030 NICK_CHANGE notify type. Deprecates the function
4031 silc_server_send_replace_id.
4033 * Added silc_server_send_notify_join to send the JOIN notify type.
4034 Deprecates the function silc_server_send_new_channel_user.
4036 * Added silc_server_send_notify_leave to send LEAVE notify type.
4037 Deprecates the function silc_server_send_remove_channel_user.
4039 * Added silc_server_send_notify_cmode and
4040 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4041 types. Deprecates the silc_server_send_set_mode function.
4043 * Added SERVER_SIGNOFF notify type to indicate that server has
4044 quit. This means that all clients on the channel from that
4045 server will drop. This can be also used when netsplit happens.
4047 Deprecated REMOVE_ID packet type since it is not needed anymore
4050 Added silc_server_send_notify_server_signoff to send the
4051 SERVER_SIGNOFF notify type. Deprecates the function
4052 silc_server_send_remove_id.
4054 Added also silc_server_send_notify_signoff to send the
4055 SIGNOFF notify type.
4057 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4058 SILC protocol from this day on. Changed the protocol
4059 specification as well.
4061 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4062 notify type. It is used between routers to notify about
4063 topic changes on a channel.
4065 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4068 * Partly updated the protocol specification to comply with the
4069 changes now made. It is still though a bit outdated.
4071 * The JOIN notify type now takes one extra argument <Channel ID>.
4072 The packet used to be destined to the channel but now the
4073 JOIN type may be sent as list thus it is impossible to
4074 destine it to any specific channel. By adding this argument
4075 it is again possible.
4077 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Added CREDITS file. The CHANGES and CREDITS file will appear
4080 in the distribution as well.
4082 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4085 types in the server's silcd/packet_receive.c.
4087 * Implemented CMODE and CUMODE to work in router environment.
4089 * Fixed minor encoding and decoding buglet from the
4090 lib/silccore/silcmode.c.
4092 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4095 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4097 * Changed all SilcConfigServer* and silc_config_server* to
4098 SilcServerConfig* and silc_server_config*, respectively.
4101 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Associated the ID (client or server ID) to the Authentication
4104 Payload to avoid any possibility of forging. Updated the
4105 protocol specification and the code accordingly.
4107 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * The RSA key length is now save to the RsaKey context in the
4110 key generation process in lib/silccrypt/rsa.c. The key length
4111 is now used to figure out the maximum size of the block allowed
4112 to be encrypted/signed.
4114 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4115 is equivalent to the silc_mp_mp2bin but does not allocate any
4118 * Changed silc_mp_mp2bin API to take length argument. If it is
4119 non-zero then the buffer is allocated that large. If zero, then
4120 the size is approximated using silc_mp_sizeinbase, which however
4123 * Created Global RNG API which is global RNG that application can
4124 initialize. After initializing, any routine anywhere in the
4125 code (including library) can use RNG without allocating a new
4126 RNG object. This was done to allow this sort of use of the
4127 RNG in code that has no chance to allocate RNG object. All
4128 applications currently allocate this and many routines in the
4129 library use this. Affected file lib/silccrypt/silcrng.[ch].
4131 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4132 it to use the Global RNG API.
4134 * Defined Authentication Payload into protocol specification that
4135 is used during SILC session to authenticate entities. It is
4136 used for example by client to authenticate itself to the server
4137 to obtain server operator privileges.
4139 Implemented this payload into the lib/silccore/silcauth.[ch].
4140 Implemented also routines for public key based authentication
4141 as the new protocol specification dictates.
4143 Moved definitions of different authentication methods from
4144 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4146 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4147 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4148 silc_pkcs_verify_with_hash functions into the file
4149 lib/silccrypt/silcpkcs.[ch].
4151 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * The client entry's userinfo pointer must be always valid.
4154 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4155 will fail since it requires the userinfo. Now, the userinfo
4156 is allocated as "" if actual userinfo does not exist. Actually,
4157 it must exist and it is totally Ok to drop client connections
4158 that does not announce the userinfo. However, we will make
4159 this workaround for now.
4161 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4162 to return the remote port by socket.
4164 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4167 SILC_SERVER_PENDING_EXEC and added an new macro
4168 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4169 data or when error occurs while processing the pending command.
4171 Added new argument `destructor' into silc_server_command_pending
4172 and to the SilcServerCommandPending object. This destructor is
4173 now called after calling the pending callback or if error occurs
4174 immediately. If error occurs the actual pending callback won't
4175 be called at all - only the destructor. The destructor may be
4176 NULL if destructor is not needed.
4178 All this applies for client library code as well. Similar
4179 changes were made there as well for the pending commands.
4181 In the client, the application must now allocate the
4182 SilcClientCommandContext with the silc_client_command_alloc
4185 * Added reference counter to the SilcServerCommandContext. Added
4186 function silc_server_command_alloc and silc_server_command_dup
4189 Same type of functions added to the client library for the same
4192 * Removed the cmd_ident from IDListData away since it is now
4193 global for all connections. It is the command identifier used
4194 in command sending and with pending commands. The affected file
4197 * Added reference counter to the SilcSocketConnection objecet to
4198 indicate the usage count of the object. The object won't be
4199 freed untill the reference counter hits zero. Currently only
4200 server uses this, and client ignores it. The client must be
4201 set to use this too later. The affected files are
4202 lib/silccore/silcsockconn.[ch]. Added also the function
4203 silc_socket_dup to increase the reference counter.
4205 This was mainly added because it is possible that the socket
4206 is removed underneath of pending command or other async
4207 operation. Now it won't be free'd and proper DISCONNECTING
4208 flags, etc. can be set to avoid sending data to connection that
4209 is not valid anymore.
4211 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4212 the connection. After that it sets SILC_SET_DISCONNECTED.
4213 It is, however, possible that the socket data is not still freed.
4214 The silc_server_packet_process now checks that data is not
4215 read or written to connection that is DISCONNECTED. The socket
4216 get's freed when the reference counter hits zero.
4218 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4220 * Changed the client operation API: channel_message operation's
4221 `sender' is now the client entry of the sender, not the nickname
4222 and the `channel' is the channel entry, not the channel name.
4224 In the private_message operation the `sender' is now also the
4225 client entry of the sender not the nickname.
4227 Affected file is lib/silcclient/ops.h and all applications
4228 using the client operations.
4230 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4232 * Moved the calling of ops->connect() from connect_to_server_final
4233 into receive_new_id functin since that is the point when the
4234 client is actually allowed to send traffic to network. The
4235 affected file is lib/silcclient/client.c.
4237 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4240 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4241 (if needs broadcasting) instead of broadcasting the packets one
4242 by one which would make a burst in the network traffic.
4244 * Added `broadcast' argument to the functions in silcd/server.[ch]
4245 silc_server_create_new_channel[_with_id] to indicate whether
4246 to send New Channel packet to primary router.
4248 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Added new function into the silcd/server.[ch] files:
4251 silc_server_create_new_channel_with_id to create new channel with
4252 already existing Channel ID.
4254 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4255 lib/silccore/silcpacket.h. This packet is used t send list of
4256 Set Mode payloads inside one packet. Server uses this to set
4257 the modes for the channels and clients on those channels, that it
4258 announced to the router when it connected to it. The protocol
4259 specification has been updated accordingly.
4261 * The silc_server_new_channel did not handle the packet coming
4262 from normal server as it normally does not send that. However,
4263 when it announces its channels it does send it. Implemented
4264 the support for that.
4266 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4267 into the file lib/silccore/id.h.
4269 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4271 * Fixed memory leaks in the functions silc_idlist_del_client,
4272 silc_idlist_del_channel and silc_idlist_del_server in the file
4273 silcd/idlist.c. All of those leaked like a sieve.
4275 * Fixed some small memory leaks in the client's function
4276 silc_client_notify_by_server.
4278 * Added functions into silcd/server.c: silc_server_announce_clients,
4279 silc_server_announce_channels and silc_server_announce_server.
4280 These functions are used by normal and router server to announce
4281 to its primary router about clients, channels and servers (when
4282 router) that we own. This is done after we've connected to the
4285 These functions effectively implements the following packet types:
4286 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4287 and SILC_PACKET_NEW_ID_LIST.
4289 * Added new functions into the silcd/packet_receive.[ch]:
4290 silc_server_new_id_list, silc_server_new_channel_list and
4291 silc_server_new_channel_user_list to handle the incoming
4292 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4294 * Added support of changing Channel ID in the function
4295 silc_server_replace_id. If the server that announces a channel
4296 to the router already exists in the router (with same name but
4297 with different Channel ID), router is responsible to send
4298 Replace ID packet to the server and force the server to change
4299 the Channel ID to the one router has.
4301 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4302 client that the Channel ID has been changed by the router. The
4303 normal server sends this to the client. Client must start using
4304 the new Channel ID as the channel's ID.
4306 Implemented handling of this new type into lib/silcclient/client.c
4307 into the function silc_client_notify_by_server.
4309 * Added new function silc_idlist_replace_channel_id into the files
4310 silcd/idlist.[ch] to replace the Channel ID.
4312 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Call silc_server_command_identify_check always when processing
4315 the IDENTIFY command in silcd/command.c
4317 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4320 send keepalive packets. The packet can be sent by clients,
4321 servers and routers.
4323 Added function silc_socket_set_heartbeat into the file
4324 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4325 If not set, the heartbeat is not performed. The actual
4326 heartbeat is implemented in the low level socket connection
4327 library. However, application is responsible of actually
4330 Added silc_server_send_heartbeat to send the actual heartbeat
4331 packet into silcd/packet_send.[ch]. Server now performs
4332 keepalive with all connections.
4334 * Added silc_task_get_first function into lib/silcutil/silctask.c
4335 to return the timeout task with shortest timeout. There was a bug
4336 in task unregistration that caused problems. TODO has been
4337 updated to include that task system must be rewritten.
4339 * The client library will now resolve the client information when
4340 receiving JOIN notify from server for client that we know but
4341 have incomplete information.
4343 * Rewrote parts of silc_server_remove_from_channels and
4344 silc_server_remove_from_one_channel as they did not remove the
4345 channel in some circumstances even though they should've.
4347 * Encryption problem encountered in server:
4349 The LEAVE command used to send the Channel Key packet to the
4350 router immediately after generating it. However, the code
4351 had earlier sent Remove Channel user packet but not immediately,
4352 ie. it was put to queue. The order of packets in the router
4353 was that Channel Key packet was first and Remove Channel User
4354 packet was second, even though they were encrypted in the
4355 reverse order. For this reason, MAC check failed. Now, this
4356 is fixed by not sending the Channel Key packet immediately but
4357 putting it to queue. However, this is more fundamental problem:
4358 packets that are in queue should actually not be encrypted
4359 because packets that are sent immediately gets encrypted
4360 actually with wrong IV (and thus MAC check fails). So, packets
4361 that are in queue should be encrypted when they are sent to
4362 the wire and not when they put to the queue.
4364 However, the problem is that the current system has not been
4365 designed to work that way. Instead, the packet is encrypted
4366 as soon as possible and left to the queue. The queue is then
4367 just purged into wire. There won't be any fixes for this
4368 any time soon. So, the current semantic for packet sending
4371 o If you send packet to remote host and do not force the send
4372 (the packet will be in queue) then all subsequent packets to the
4373 same remote host must also be put to the queue. Only after the
4374 queue has been purged is it safe again to force the packet
4377 o If you send all packets immediately then it safe to send
4378 any of subsequent packets through the queue, however, after
4379 the first packet is put to queue then any subsequent packets
4380 must also be put to the queue.
4382 Follow these rules and everything works fine.
4384 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4386 * Added new function silc_server_remove_clients_by_server to
4387 remove all client entries from ID list when the server connection
4388 is lost. In this case it is also important to invalidate all
4389 client entires as they hold the invalid server entry. This
4390 fixes fatal bug when server has lost connection and will reconnect
4393 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Made some sanity checks to silc_server_daemonise like to check
4396 whether the requested user and group actually exists.
4398 * Added sanity check to SKE's silc_ske_responder_finish to check
4399 that the public and private key actually is valid.
4401 * Invalidate the client's nickname when receiving Replace ID
4402 packet and the Client ID is being replaced. This means that the
4403 server will query the nickname if someone needs it (client)
4406 * Sort the ID Cache in client library when the ID Cache data
4407 has changed (needs sorting).
4409 * Do not allow for SILC client to create several connections to
4410 several servers. The client does not support windows right now
4411 and generating multiple connections causes weird behaviour.
4413 Irssi-silc client does support windows and can handle several
4414 connections without problems, see: www.irssi.org and SILC plugin.
4416 * Fixed some places where client was added to the IDList. The
4417 rule of thumb is following (in order to get everything right):
4418 If the client is directly connected local client then the
4419 `connection' argument must be set and `router' argument must be
4420 NULL to silc_idlist_add_client function. If the client is not
4421 directly connected client then the `router' argument must
4422 bet set and the `connection' argument must be NULL to the
4423 silc_idlist_add_client function.
4425 * The funtion silc_server_packet_send_local_channel actually did
4426 not check whether the client was locally connected or not. It
4427 does that now. Fixed a bug related to LEAVE command.
4429 * Fixed Remove Channel User payload parsing bug in server's
4430 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4432 * The server's silc_server_save_channel_key now checks also the
4433 global ID list for the channel as it might not be in the local
4434 list. Fixed a bug related to LEAVE command.
4436 * Is this the end of the [<unknown>] buglet that has been lurking
4437 around for a long time? A little for loop fix in server's
4438 silc_server_command_whois_parse that is used by both IDENTIFY
4439 and WHOIS command. At least, this was a clear bug and a cause
4440 of one type of [<unknown>] buglet.
4442 * WHOIS and IDENTIFY commands call the function
4443 silc_server_command_[whois/identify]_check function even if
4444 we are not router server.
4446 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Added --with-gmp configuration option. If set the GMP
4449 is always compiled in the SILC source tree. If not set then
4450 it is checked whether the system has the GMP3 installed. If
4451 it has then the GMP won't be compiled (the system's headers
4452 and library is used), if it doesn't have it then the GMP is
4453 compiled in the SILC source tree.
4455 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Changed RSA private exponent generation to what PKCS #1
4458 suggests. We try to find the smallest possible d by doing
4459 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4460 not security fix but optimization.
4462 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4464 * Added new config entry [Identity] to fork the server and run
4465 it as specific user and group. A patch from Bostik.
4467 * Imported Dotconf configuration library into lib/dotconf.
4468 This will be used to create the SILC configuration files later.
4469 It will appear in the distsribution after this commit.
4471 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * A big code auditing weekend happening. Auditing code for
4474 obvious mistakes, bugs and errors. Also, removing any code
4477 Removed files for being obsolete:
4479 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4480 inline in the file lib/silcutil/silcbuffer.h)
4482 o lib/silcutil/silcbufutil.c (the header has inline versions)
4484 Changed code to fix possible error conditions:
4486 o The buffer formatting routines now check that the destination
4487 buffer really has enough space to add the data. This applies for
4488 both buffer formatting and unformatting
4489 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4490 unformatting was changed to accomodate following rules:
4491 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4492 sent to the function while XXX_*STRING will not allocate or copy
4493 the data into the buffer. Instead it sets the pointer from the
4494 buffer into the pointer sent as argument (XXX_*STRING used to
4495 require that the pointer must be allocated already). This change
4496 makes this whole thing a bit more consistent and more optimized
4497 (note that the data returned in the unformatting with XXX_*STRING
4498 must not be freed now). The routines return now -1 on error.
4500 o Tried to find all code that use buffer_format and buffer_unformat
4501 and added return value checking to prevent formatting and
4502 especially unformatting errors and possible subsequent fatal
4505 o Changed ske->x and ske->KEY to mallocated pointers in
4506 lib/silcske/silcske.h. Fixed possible data and memory leak.
4508 o Added return value checking to all *_parse* functions. Fixed
4509 many memory leaks as well.
4511 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4512 so that buffer overflows would not happen. All code now also
4513 checks the return value as it can fail.
4515 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4517 * Added reconnection support to server if the normal server looses
4518 its connection to the router (for example if router is rebooted).
4519 The server performs normal reconnection strategy implemented
4520 to the server. Affected file silcd/server.c.
4522 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Added new packet type SILC_PACKET_SET_MODE that is used to
4525 distribute the information about changed modes (for clients,
4526 channels and clients channel modes) to all routers in the
4527 network. Updated the protocol specification accordingly.
4529 Added functions into silcd/packet_send.c and
4530 silcd/packet_receive.c: silc_server_send_set_mode,
4531 silc_server_set_mode.
4533 Added new files silcmode.[ch] into lib/silccore that implements
4534 the encoding and decoding of Set Mode Payload. Added new type
4535 SilcSetModePayload. Moved the definitions of different modes
4536 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4538 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Oops, a little mistake in server's connection authentication
4541 protocol. The protocol is not ended with FAILURE but with
4542 SUCCESS if the authentication is Ok. :) Affected file is
4545 * Implemented NICK_CHANGE notify handling in server in the file
4546 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4547 the local clients on the channel. After the changing nickname
4548 in router environment snhould work and the [<unknown>] nickname
4549 should appear no more.
4551 The silc_server_replace_id function that receives the Replace ID
4552 payload now sends the NICK_CHANGE notify type also in the file
4553 silcd/packet_receive.c
4555 * Changed WHOIS and IDENTIFY command to support the maximum amount
4556 of arguments defined in protocol specs (3328 arguments). This
4557 fixed a bug that caused problems when there were more than three
4560 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Added extra parameter, command identifier, to the
4563 silc_client_send_command so that explicit command identifier
4566 Changed that ID list routines uses specific command identifier
4567 when sending WHOIS/IDENTIFY requests to the server so that they
4568 can be identified when the reply comes back.
4570 Affected files lib/silcclient/command.[ch],
4571 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4573 * Added `sender' argument to silc_server_packet_send_to_channel
4574 to indicaet the sender who originally sent the packet to us
4575 that we are now re-sending. Ignored if NULL. Affected file
4576 silcd/packet_send.[ch].
4578 * Added some server statistics support in silcd/server_internal.h
4579 SilcServerStatistics structure and around the server code. Also
4580 send some nice statistics information when client is connecting
4583 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Fixed channel ID decoding in server's JOIN command reply in
4586 silcd/command_reply.c
4588 * Fixed braodcasting of replace ID payload to not to send it if
4589 we are standalone server in silcd/packet_receive.c.
4591 * Fixed all channel message sending routines to not to send
4592 packets to clients that has router set, since they are routed
4593 separately in the same function earlier. Affects file
4594 silcd/packet_send.c and all channel packet sending functions.
4596 * In USERS reply, res_argv[i] are not allocated, the table
4597 is allocated. Thus changed that free the table, not its
4600 * In server's whois_check and identify_check if the client is
4601 locally connected do not send any WHOIS commands - they are not
4604 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Fixed some minor bugs in client when sending WHOIS command. The
4607 arguments was in wrong order.
4609 * Removed statis function add_to_channel from server in
4610 silcd/command.c that was previously used with the joining but
4613 * Tested USERS command in router environment successfully with two
4614 routers, two servers and two clients.
4616 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Reorganized the USERS command and command reply in client library
4619 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4620 When the command is given by user we register a pending command
4621 callback that will reprocess the command after the reply has been
4622 received from the server. When reprocessing the packet we then
4623 display the information. Thus, the USERS information is displayed
4624 now in the command callback instead of in the command reply
4625 callback. The processing of the command is same as previously
4626 when server has sent the command reply in the JOINing process.
4628 * Added to USERS command in silcd/command_reply.c to join the client,
4629 we didn't use to know about, to the channel after we've created
4630 a client entry for it. Also, for clienet we did know already still
4631 check whether it is on the channel or not and add it if not.
4633 * Removed silc_server_command_join_notify as the function and its
4636 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Changed the client's pending command handling to the same as the
4639 server's pending command handling. It is also now possible to
4640 execute command reply functions from other command reply
4641 function as the function callbacks for commands and command
4642 replies are one and same. The pending commands are not static
4643 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4644 in client connection context. Thus, pending commands are server
4645 connection specific as it is convenient.
4647 Changed the function silc_client_command_pending and
4648 silc_client_command_pending_del and added new function
4649 silc_client_command_pending_check. Removed the
4650 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4653 * Added cmd_ident, current command identifier, to the client
4654 connection context in lib/silcclient/client.h to keep track on
4655 command identifiers used in command sending. Client's command reply
4656 function handling now supports the mandatory command identifiers.
4658 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4659 funtions in client to fully support pending command callbacks.
4661 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4662 as one of the arguments to the application in the command reply
4665 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4666 before first releasing SILC but came back. Now it is removed again
4667 and should come back nomore. The FORWARDED flag was used only
4668 by the JOINing procedure by forwarding the command packet to router.
4669 Now, the JOINing procedure has been changed to more generic (due
4670 to various router environment issues) and FORWARDED is not needed
4671 anymore for anything. The protocol specification is yet to be
4674 Now, removed silc_server_packet_forward from server and the flag
4675 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4677 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Renamed NAMES command to USERS command. The NAMES was named that
4680 due to historical reasons. Now it is renamed. Also, rewrote
4681 parts of the USERS command. The nickname list is not sent anymore
4682 by the server. Only Client ID and mode lists are sent in the USERS
4683 command. Changed this also to the protocol specification.
4685 The client now resolves the names and stuff after it receives
4686 the USERS list from the server when joining to the channel.
4688 * WHOIS and IDENTIFY commands has been changed to support multiple
4689 Client ID's per command. One can now search for multiple users
4690 in the network by sending only one WHOIS or IDENTIFY command.
4691 Changed the code and the protocol specifications.
4693 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4694 uses silc_server_command_whois_parse to parse the request. */
4696 * If normal server, do not parse the WHOIS and IDENTIFY requests
4697 before sending it to the router. Saves some time.
4699 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4701 * Fixed JOIN command on client library. Wrong number of arguments
4702 used to crash the client.
4704 * Added silc_server_channel_has_global function to check whether
4705 channel has global users or not.
4707 * Added silc_server_channel_has_local function to check whether channel
4708 has locally connected clients on the channel.
4710 * The silc_server_remove_from_one_channel now checks whether the
4711 channel has global users or not after given client was removed from
4712 the channel. It also checks whether the channel has local clients
4713 on the channel anymore. If it does not have then the channel entry
4714 is removed as it is not needed anymore.
4716 * The silc_server_notify now checks on JOIN notify whether the joining
4717 client is one of locally connected or global. If it is global then
4718 the channel has now global users on the channel and that is marked
4719 to the channel entry. Also, it now saves the global client to
4720 global list who is joining and JOINs it to the channel. This is
4721 for normal server, that is.
4723 Changed silc_server_send_notify_on_channel,
4724 silc_server_packet_relay_to_channel and
4725 silc_server_packet_send_to_channel check if we are normal server
4726 and client has router set (ie. global client) do not send the
4727 message to that client, as it is already routed to our router.
4729 * Implemented LEAVE notify type handling in silc_server_notify
4732 * Tested LEAVE command in router environment successfully. Tested
4733 with two routers, two servers and two clients.
4737 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4739 * Implemented SIGNOFF notify type handling in silc_server_notify
4742 * silc_server_remove_id now removes the client entry from all channels
4743 it has joined and thusly sends SIGNOFF notify type.
4745 * Rewrote the NAMES list generation in server by removing two excess
4746 loops. The lists are created now inside one loop.
4748 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * silc_server_remove_channel_user checks now also global list
4751 for channel and client.
4753 * silc_server_new_channel_user checks now both local and global
4754 list for channel and client. Fixed a bug in client id decoding.
4755 Used to decode wrong buffer.
4757 * silc_server_channel_message checks now both local and global
4758 list for channel entry.
4760 * Tested channel joining (hence JOIN) in router environment
4761 successfully. Tested with two routers, two servers and two
4764 * Tested channel message sending in router environment successfully.
4766 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4768 * Added silc_server_save_channel_key into server.[ch] to save the
4769 received channel key in Channel Key payload processing. It is
4770 also used in JOIN command reply handling.
4772 Equivalent function silc_client_save_channel_key added into
4773 client.[ch] into client library.
4775 * Changed JOIN command reply to send information whether the channel
4776 was created or not (is existing already) and the channel key
4777 payload. Changed protocol specs accordingly.
4779 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4780 the request was sent by ID and not by nickname. Crashed on
4783 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4786 now correctly save the received data.
4788 * silc_server_free_sock_user_data now notifies routers in the
4789 network about entities leaving the network.
4791 At the same time implemented functions silc_server_remove_id
4792 and silc_server_send_remove_id to receive and send REMOVE_ID
4793 packets. The packet is used to notify routers in the network
4794 about leaving entities. The ID removed will become invalid in
4797 * Added function silc_idlist_del_server into server. Removes and
4798 free's server entry from ID list.
4800 * silc_server_private_message function now checks, if we are router,
4801 that the destination ID really is valid ID, naturally.
4803 * In router when NEW_ID packet is received (for new client) the
4804 hash of the Client ID is saved in the ID Cache but the
4805 client->nickname is set to NULL, instead of putting the hash
4808 IDENTIFY command now also checks that client->nickname must be
4809 valid. If it is not if will request the data from the server who
4810 owns the client. Added new function
4811 silc_server_command_identify_check.
4813 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4814 to set the command to already allocated Command Payload.
4816 * Tested private message sending in router environment with two
4817 routers, two servers and two clients. Fixed minor bugs and now
4820 * Fixed segfault from client's NAMES command. Used to crash if
4823 * Forwarded packets must not be routed even if it is not destined
4824 to the receiver. Changed server code comply with this.
4826 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Added `require_reverse_mapping' boolean value to ServerParams
4829 structure. If TRUE (not default) the server will require that
4830 the connecting host has fully qualified domain name.
4832 If the reverse mapping is not required and hostname could not be
4833 found the IP address is used as hostname.
4835 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4837 * Implemented version string checking to both client and server.
4838 The check is incomplete currently due to the abnormal version
4839 strings used in development version of SILC.
4841 * Changed all command functions in server to use the new
4844 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Changed char *data to unsigned char *data in ID Cache system to
4847 support binary data as ID Cache data. Changed code to support
4848 binary data in lib/silccore/idcache.c.
4850 * Renamed silc_server_packet_relay_command_reply to
4851 silc_server_command_reply as it is normal packet receiving
4852 function. Rewrote the function to accept command replys for
4853 servers and not only for clients.
4855 * Mark remote router always as registered server if we are connecting
4856 to it. Otherwise, commands sent by the router to us are ignored.
4858 * All ID List find routines now returns the ID Cache Entry pointer
4859 as well if requested.
4861 * WHOIS command works now in router environment, tested with two
4862 routers, two servers and two clients.
4864 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4865 in router environment (as it is almost equivalent to WHOIS) but
4866 hasn't been tested thoroughly. Added new functions:
4868 silc_server_command_identify_parse
4869 silc_server_command_identify_send_reply
4870 silc_server_command_identify_from_client
4871 silc_server_command_identify_from_server
4873 * Disabled route cache adding because adding two different ID's with
4874 same IP replaces the old cache entry thus giving wrong route.
4875 The entry->router->connection is always the fastest route anyway
4876 so route cache may not be needed. Of course, new routes maybe
4877 established after receiving the ID when the entry->router->connection
4878 might not be anymore the most optimal.
4880 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Add route cache for received ID for fast routing.
4884 * Added silc_server_packet_route to route received packet on router
4885 that is not destined to us.
4887 * Renamed silc_server_get_route to silc_server_route_get.
4889 * Added id_string and id_string_len fields into SilcServer to
4890 include encoded ServerID for fast comparing without excess
4891 encoding of the ID's.
4893 * Cleaned up WHOIS command on server side. Added following static
4896 silc_server_command_whois_parse
4897 silc_server_command_whois_check
4898 silc_server_command_whois_send_reply
4899 silc_server_command_whois_from_client
4900 silc_server_command_whois_from_server
4902 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4903 arguments in command replies. All command functions should be
4904 updated to use this macro.
4906 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4908 * Minor typo fixes on command reply handling on server.
4910 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4912 * Added silc_server_command_add_to_channel internal routine to add
4913 the client to the channel after router has created the channel and
4914 sent command reply to the server.
4916 * Added generic silc_server_send_command to send any command from
4919 * Use static buffer with ID rendering instead of duplicating data.
4921 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4923 * Fixed a channel user mode bug when joining to a channel server gave
4924 everybody channel founder rights, oops.
4926 * We mark ourselves as the router of the incoming server connection
4927 if we are router ourselves. This way we can check in some packet
4928 sending functions whether it is locally connected server. For
4929 incoming router connections we put NULL.
4931 * For router sending packets locally means now always sending the
4932 packet cell wide; to local clients and local servers. For normal
4933 server sending packet locally means sending it to only local
4936 * Fixed the JOIN command to really work in router environment. If the
4937 channel is created it is always created by the router. Router is
4938 also responsible of making the initial joining to the channel,
4939 sending JOIN notify to the sending server and distributing
4940 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4941 does not exist server doesn't do anything else but forward the
4942 command to the router which performs everything.
4944 * Added silc_server_send_channel_key function to send the Channel Key
4947 * Added silc_server_create_channel_key to create new channel key. The
4948 channel key is now re-generated everytime someone joins or leaves
4949 a channel, as protocol dictates. Note: channel->key_len is the
4952 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4955 packet_receive.[ch] to separate packet sending and receiving
4956 routines. The server.[ch] now includes everything else including
4957 actual packet processing (writing and reading data) and other
4960 Renamed silc_server_private_message_send_internal to
4961 silc_server_send_private_message. The routine is still though
4962 used only to relay private messages as server does not send
4963 private messages itself.
4965 Renamed silc_server_new_channel to silc_server_create_new_channel
4966 and added new function sicl_server_new_channel that handles the
4967 incoming New Channel packet. Added also new sending function
4968 silc_server_send_new_channel to send New Channel Payload.
4970 * Added new function silc_server_notify to process incoming notify
4971 packet to the server/router. Server may then relay the notify
4972 to clients if needed.
4974 * Added new function silc_server_new_channel_user to process incoming
4975 New Channel User packet. Router will redistribute the packet and
4976 send JOIN notify to its local clients and locally connected servers
4977 if needed. Normal server will send JOIN notify to its local client
4978 on same channel when received this packet. Added also corresponding
4979 sending function silc_server_send_new_channel_user to sent the
4982 * Added boolean route argument to send_notif_to_channel and
4983 packet_send_to_channel functions to attempt to route the packet
4984 if it is TRUE and send only locally if it is FALSE.
4986 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * silc_server_replace_id now broadcasts the received replace ID
4989 packet if it is not broadcast packet already. The router must
4990 broadcast to inform other routers about changed ID.
4992 * Added backpointer to server's router into SilcServer context in
4993 silcd/server_internal.h.
4995 * Fixed silc_server_packet_broadcast to send correct broadcast
4998 * The channel key is now distributed to the local client as soon
4999 as it is received from the router (in router environment) so that
5000 no other packet may be sent for the channel until client has
5003 * silc_server_remove_channel_user now broadcasts the received
5004 Remove Channel User packet if it is not broadcast packet already.
5005 The router must broadcast to inform other routers about removed
5008 * Added users field into SilcPacketContext that is a reference count
5009 of the context. One can increase the reference count by calling
5010 silc_packet_context_dup which is now changed to just increase the
5011 reference count instead of duplicating the data. The reference
5012 count is decresed by calling silc_packet_context_free that will
5013 free the data after the reference count hits zero.
5015 For now on the packet context and everything allocated into it
5016 (including the raw packet from network) must be freed by calling
5017 the new silc_packet_context_free function. Added also new function
5018 silc_packet_context_alloc that must be used now to allocate the
5019 context. This also means that if a routine is asynchronous from
5020 silc_[client/server]_packet_parse_type the packet context must
5021 be duplicated by calling silc_packet_context_dup. Otherwise it
5022 gets free'd after silc_[client/server]_packet_parse_type returns.
5023 Also, one must remember that if packet is duplicated then its
5024 reference count must be decresed by calling the free function as
5025 many times as it was duplicated.
5027 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5028 from both client and server.
5030 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Made joining to a channel working in router environment.
5034 * Cleaned up JOIN command on server side and create function
5035 silc_server_command_join_channel internal routine to make the
5038 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Changed silc_command_pending list to SilcDList. Also, added
5041 `ident' field to SilcServerCommandPending structure to identify
5042 the reply and to call correct callback.
5044 Added silc_server_command_pending_check function to replace the
5045 corresnponding macro. The silc_command_pending list is not
5048 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5049 to set identifier to previously allocated Command Payload. It
5050 is used to set identifier for command when resending Command
5053 * Added silc_command_payload_encode_payload to encode Command
5054 Payload buffer from SilcCommandPayload structure.
5056 * Added silc_argument_payload_encode_payload to encode Argument
5057 payload buffer from SilcArgumentPayload structure.
5059 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Changed WHOIS command to support router connection on server side.
5062 The whois request is always sent to router unless the server is
5063 standalone server. After server has received the reply from the
5064 router will it send the reply to the client.
5066 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5067 broadcast received broadcast packet. The function is used only
5068 by router. The broadcast packet is always sent to the router's
5071 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5072 render given ID to printable string, for log files for example.
5074 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Made basic router to router connections working. At least they
5077 can now connect to each other but nothing really works the way
5078 they are supposed - yet.
5080 * Added new initiator token to RouterConnection configuration
5081 file in silcd/serverconfig.[ch]. It is used to tell whether we
5082 are the initiator to the remote router or whether we'll expect
5083 the other end to connect.
5085 * Moved registering of listener task to silc_server_init, hence
5086 the server starts listenning as soon as it is run, even if it
5087 does not have connections to other routers. Let's see how well
5090 * Changed default connection retry timeouts for more suitable in
5093 * Removed cipher and such arguments from silc_idlist_add_client
5094 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5095 Added new function silc_idlist_add_data to add the keys and stuff
5098 * Added SilcIDListData structure and added it to SilcClientEntry
5099 and SilcServerEntry as their first field in the structure. This
5100 way we can explicitly cast the ID entries to the SilcIDListData
5101 structure and get common data for the entries. In past, we had
5102 to first check what type of connection it is and then cast it to
5103 correct ID entry type. Now, we can directly cast the opaque
5104 pointer to the SilcIDListData (no matter what ID entry it actually
5105 is) and get the data needed.
5107 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5110 in some circumstances even if threre were timeout tasks, though not
5111 IO tasks, but tasks anyway. Now fixed.
5113 * Defined SilcServerConnection structure to hold connection specific
5114 stuff about directly connected servers and routers. The definition
5115 is currently in silcd/server_internal.h. I thought about having
5116 a bit more important role fro this struct but for now it is used
5117 only when connecting to other server (or router actually).
5119 * Added connecting retry support in server when connecting to
5120 router(s). The retry feature implement exponential backoff
5121 algorithm. Also, added SilcServerParams structure to hold default
5122 parameters for server. For now, it include these retry settings
5123 and are hard coded. After server is moded to be as Silc Server
5124 Library this structure will be more important.
5126 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Changed client librarys channel->clients table to SilcList and
5129 changed code accordingly.
5131 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Changed client's channel table to SilcList and changed code
5134 accordingly. Also changed SilcChannelClientEntry to include back-
5135 pointer to the channel so that client entry can use that structure
5136 as list as well and we have fast cross-reference to the channel.
5137 This change dramatically decreased the complexity of channel
5138 handling with client entry and vice versa (removed one extra
5139 loop when searching for channel entry from many functions).
5141 * Changed server->sim from table to SilcDList and changed code
5144 * NAMES command can now be used from user interface. It will show
5145 the user list on the channel, neatly.
5147 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5148 Code now saves realname of the user if it becomes available.
5150 * Renamed configure.in to configure.in.pre and made ./prepare
5151 script to automatically add correct version string to
5152 configure.in which it creates from configure.in.pre.
5154 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5156 * NAMES command reply now shows users mode with the nickname when
5159 * Moved silc_client_ch[u]mode[_char] functions from
5160 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5161 place sucks, they are utility functions and should be in some
5164 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5166 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5169 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Added TRQ (efficient deque and list library) into lib/trq. This is
5174 a very good list library that is currently used in the SILC. Defined
5175 SilcList API over the library because I didn't like the API very
5176 much. See lib/trq/silclist.h for the API and examples of how to
5177 use the API. Fixed various places in the code to use the new
5178 SilcList API. The SilcList is meant for lists that has a structure
5179 already defined as a list. It is not suitable to add just some
5180 context to the list (in TRQ, the context is the list actually).
5182 So, I defined SilcDList that can be used for the purpose where
5183 predefined list structure does not exit. This can be used as
5184 such list. Now some context just can be added to the SilcDList.
5185 Currently this list is not used in the SILC just yet, though there
5186 are a lot places where this can replace dynamically allocated
5187 tables and I will fix these places, later, to use SilcDList.
5188 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5189 and use TRQ internally).
5191 Also fixed some annoying warning messages that the original TRQ
5192 code generated. Also minor changes to TRQ's Makefile.in.
5194 * Added support for querying by Client ID to both WHOIS and
5195 IDENTIFY commands into server, as required by the protocol.
5197 * Removed method function pointers from SilcBuffer structure. They
5198 weren't used to anything and just increased the context size for
5199 no good reason. This change also made silc_buffer_alloc and
5200 silc_buffer_free functions inline functions.
5202 * Disabled command flooding detection support until it's fixed so
5203 that it accepts commands in but does not execute them more than once
5206 * Added silc_net_localhost(), to return local hostname, into
5207 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5208 that must be initialized before calling silc_client_init.
5210 * Added new function: silc_server_send_notify_on_channels to send
5211 notify messages to all channels client has joined. It is assured
5212 that the message is sent only once per client.
5214 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5215 lib/silcutil/silcutil.[ch] as silc_format function. The new
5216 function is generic and is used by server as well, not only by
5217 the logging routines.
5219 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5220 the provided version string was not acceptable. Added new function:
5221 silc_ske_check_version into lib/silcske/silcske.h. The function
5222 must be implemented by the application (client or server) and it
5223 does not reside in the SKE library. The function checks the version
5224 string remote end sent.
5226 * Added back pointers (to opaque context and to SilcSocketConnection)
5227 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5229 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5230 duplicate packet context structure.
5232 * Changed `notify' client operation to send same arguments as client
5233 receives from server except for ID's. ID's are mapped to correct
5234 ID entry and that is returned. Also, if channel entry is not sent
5235 by server but the notify is for channel the channel entry is sent
5236 to application (otherwise application doesn't know that it is for
5237 channel (library gets it from packet's Destination ID)).
5239 * Added silc_client_remove_from_channels into client library to
5240 remove a client from all channels it has joined to. Used when
5241 received SIGNOFF notify from server. Added also new function
5242 silc_client_replace_from_channels to replace old ID entry with
5243 new ID entry on all channels. Used when received NICK_CHANGE
5246 * Fixed ID Cache list handling in silc_idlist_get_client in
5247 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5248 to get (or query) client by ID.
5250 * Updated TODO list.
5252 * Added connection authentication status message defined by the
5253 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5254 support for these into the code in client and server side.
5256 * Added generic function silc_client_send_command to send any command
5257 with variable argument list. Application should use this function
5258 to send commands if the command functions provided by the library
5259 does not suite for the application's user interface needs.
5261 * Added new `failure' client operation. Application is notified about
5262 received failure packet if client is executing a protocol. In this
5263 case the protocol's execution has failed.
5265 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5266 is required by the protocol.
5268 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5269 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5272 * Added status flag to SilcSKE object to indicate realtime status
5273 of the SKE protocol.
5275 * Application receives now exactly same command reply arguments as
5276 the library receives from server. However, if ID is received the
5277 corresponding ID entry is returned to the application (eg. Client
5278 ID is mapped to correct SilcClientEntry entry and that is returned).
5279 Changed command_reply client operation due to this change.
5281 * Changed all ID's in commands and in command replys as ID Payloads.
5282 Change affected both client and server side codes.
5284 All ID's sent in SILC network (with execption of ID's in SILC
5285 Packet header) are sent in ID Payload to support variable length
5288 * Server now notifies nick changes and notifies all clients on
5289 the channels about the new nickname (about the new Client ID,
5292 * Implemented CMODE command to change channel modes. Supports all
5293 channel modes defined by the protocol specs except ban and invite
5294 lists. (Also, private channel key mode is supported but support for
5295 setting private channel key in client is missing, thus, this mode
5296 has no effect on client side (except that server requires that the
5297 client uses private channel key and normal channel traffic does not
5300 Also, invite mode works per se, but INVITE command does not work
5301 yet correctly, so you can set channel as invite only channel but
5302 inviting clients to the channel does not work (it is yet to be
5303 thought what's the best way to do it).
5305 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5306 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5307 Implemented CUMODE command to change user's mode on the channel.
5308 Supports all modes defined by the protocol specs.
5310 * Added NAMES command reply to return users modes on the channel.
5312 * Removed unnecessary and slow ciphers from lib/silccrypt.
5314 * Set SO_KEEPALIVE option to connection sockets by default.
5316 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5318 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5319 redefined the Notify Payload into protocol specs.
5321 * Added silc_id_payload_parse_id to get ID directly from raw
5324 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5327 accept searching by Client ID as well.
5329 * Added support for LEAVE and SIGNOFF notify types in client library.
5331 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5332 to parse ID Payload from raw data.
5334 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5336 * Added flags parameter into silc_ske_assemble_security_properties
5337 function in lib/silcske/silcske.[ch].
5339 * Changed notify client operation to fit better for notify messages
5340 sent by server. The notify payload received from server is now
5341 passed to the application (after parsing it to SilcNotifyPayload).
5342 It is application's responsibility to retrieve the arguments
5343 from the payload and show the message the way it wants. The message
5344 sent by server is implementation specific.
5346 * Changed public keys to comply with the protocol specification.
5347 Old public keys are not supported anymore and are not compatible.
5349 * Removed nickname from Channel Payload as the latest draft removed
5350 it. The client must resolve the nickname from the NAMES command
5351 reply received when it joined the channel.
5353 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5355 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5357 * Fixed some errors in protocol specification drafts.
5359 * Created lib/silccore/silcnotify.c to implement Notify Payload
5360 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5361 generic payloads described by protocol specifications. The file
5362 includes implementations for ID Payload and Argument Payload.
5364 * Changed Command Payload implementation to use the new Argument
5365 Payload. Changed command_xxxx_payload to command_payload_xxxx
5366 to comply with SILC coding conventions.
5368 * Added suppport for Argument Payload handling in Notify Payload
5369 implementation as protocol requires it. Added the new support
5370 into server and client lib as well.
5372 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added support for multiple nicknames on same channel. [n] is
5375 added locally to the nickname if there are more than one same
5376 nicknames on the channel.
5378 * Server now sends all nicknames that matched WHOIS request.
5379 Client also shows the list received from server.
5381 * Added TOPIC command to client side. User can now set and show
5382 current topic on channel.
5384 * Added MOTD command to client and server. Also, server sends the
5385 motd when client connects to the server.
5387 * Changed version strings to comply ISO 8601.
5389 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Fixed protocol error handling in client library. It should now
5392 cope even if the SKE fails for some reason.
5394 * Made new protocol specification drafts for submitting to IETF.
5396 * Implemented TOPIC command to server in silcd/command.c.
5398 * Added two new notify types into lib/silccore/silcnotify.h:
5399 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5400 notify nickname change and topic setting/change on a channel.
5402 * API change of command_reply operation in client library. The
5403 application gets now the status type received from server as well.
5405 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5409 * Cras fixed and optimized the packet handling even further and
5410 it should work now. Minor change to the prototype of function
5411 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5413 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added new function into lib/silcutil/silcschedule.[ch]:
5416 silc_schedule_with_fd to select() a specified fd. The function
5417 returns after timeout expires or data arrives or goes. The
5418 function is used by packet routines to wait that all data is
5419 received from network.
5421 * Fixed data reading from network in lib/silccore/silcpacket.c.
5422 The code now assures that all data is read from the fd and then
5423 continues packet processing. This was a bug fix since the code
5424 used to drop some data in some circumstances.
5426 * Added new function into lib/silcclient/client.[ch]:
5427 silc_client_start_key_exchange to start key exchange after
5428 connection has been established to server. The code internally
5429 now uses this funtion but its main purpose was to provide it
5430 for applications that perform their own connecting. After
5431 application has created a connection it merely calls this
5432 function to start the key exchange between client and server.
5433 The library takes care of everything else after that.
5435 Updated also lib/silcclient/README to explain the usage of
5438 * Do not send to application information that connection has
5439 been established. Application gets notified it by connect
5442 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Applied cras's patch to add silc_schedule_one function. The
5445 function runs scheduler once and returns.
5447 * Fixed the scheduler after cras messed it up. The timeout
5448 handling works now as it's supposed to work.
5450 * Added into lib/silccore/ silcnotify.h to include notify
5451 message types support. Changed silc_server_send_notify*
5452 functions, in server.[ch], to support those new notify types.
5453 Added the support for the notify types into client library,
5454 as well. Added new notify client operation into ops.h in
5457 * Changed silc_server_packet_send_to_channel to send normal
5458 packets instead of just channel message packets. The function
5459 is now used to send the notify packets to channels. It is not
5460 used to send channel message packets anymore, as server never
5463 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5464 va_arg()s as it seems to require it nowadays. I guess, if SILC
5465 is compiled with older va_arg() the new code should work anyway.
5467 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Splitted core library. Core library (lib/silccore) includes
5470 now only SILC protocol specific core (and common) components.
5471 Created new utility library (lib/silcutil) that includes more
5472 generic purpose stuff. The stuff for util library was taken
5473 from the old core library. This was minor and easy split.
5475 * Created SILC Client Library (lib/silcclient) that includes
5476 implementation of the SILC client without user interface. This
5477 was major move from silc/ directory. The code has been changed
5478 so that it is transparent towards the user interface. The
5479 silc/ directory includes now the same user interface as before
5480 and it uses the new client library. Read lib/silcclient/README.
5481 Basicly, the client library performs everything else related
5482 to SILC except user interface handling. Also, configuration
5483 files are considered to be part of user interface and library
5484 does not handle them.
5486 This change also changed a lot of structures, function naming etc.
5487 Most important change was that SilcClientWindow object was
5488 renamed to SilcClientConnection in the client library. Created
5489 also new file lib/silcclient/ops.h. Also added new files
5490 silc/local_command.[ch] and silc/client_ops.[ch].
5492 All these changes were made to make it easier for user interface
5493 designers to create what ever user interface for the SILC client
5496 It is also expected that the server will be moved to lib
5497 directory as well and SILC Server Library will be created;
5498 sometimes in the future.
5500 * Removed Local commands from lib/silccore/silccommand.h as
5501 they are application specific and new client library does not
5502 handle any of those anymore.
5504 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5505 old client implementation in silc/.
5507 * Added support for callback functions in SILC_LOG_* macros.
5508 Application can now set its own callbacks that will be called
5509 instead of using the default functions that will always print
5510 the debug messages to stderr (or stdout). Also, debugging can
5511 now be disabled by setting silc_debug to FALSE and re-enabled by
5512 setting it to TRUE. Note, that logging will still work even
5513 if debugging is disabled.
5515 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5516 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5517 silc_log_reset_debug_callbacks.
5519 * To enable debugging in silc client one must give now -d
5520 option on command line.
5522 * Changed silc_schedule_init to automatically allocate task queues
5523 if they are not allocated before calling it.
5525 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added GMP 3.1 into math library.
5529 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5532 a channel in SILC network. The packet is used by servers and
5533 routers to notify other routers that user has left a channel.
5534 This little feature was missing until now. Added the feature
5535 to protocol specification as well.
5537 Added functions: silc_server_send_remove_channel_user and
5538 silc_server_remove_channel_user into server.[ch].
5540 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5541 lib/silccore/silcpacket.h. However, they are not implemented
5544 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed joining to a channel and sending channel messages
5547 between server and router. The channel message sending should
5548 now work inside a cell.
5550 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5552 * Fixed the private message sending between server and router.
5553 The private message sending should now work inside a cell.
5555 * Added silc_server_replace_id into server.[ch] to replace
5556 existing ID in the SILC network.
5558 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5559 and silc_idlist_replace_server_id into idlist.[ch] in server.
5561 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Fixed the server to server connections. Server can again now
5564 connect to router. Router to router connections probably does
5567 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Added dynamic protocol registering support. Now protocols can
5570 registered and unregistered on the fly. Patch by cras.
5572 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5574 * Added lib/contrib directory to hold routines that some platforms
5575 don't have but are needed by SILC.
5577 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5578 into lin/contrib to provide getopt() and getopt_long() for
5579 those who don't have it.
5581 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5583 * Added AWAY command to client. When away message is set and
5584 client receives a private message packet the client automatically
5585 replies to the sender with the away message.
5587 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5588 bug seemed to be the cause of recent problems when compiling
5591 * Added version detection support to SKE protocol specification
5592 and added the new changes to the SKE implementation as well.
5593 There were other minor changes in the SKE protocol as well.
5595 Many changes in lib/silcske/silcske.[ch] and in
5596 lib/silcske/payload.[ch].
5598 * Added ^U functionality, clear input line. Patch from cras.
5600 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Mainly small bugfixes on core library. Fixed some debugging
5603 logging and buffer overflow in silclog.c.
5605 * Updated config.sub and config.guess on the distribution tree.
5607 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added command lagging support in server. Client may execute
5610 commands now only once in two seconds.
5612 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Optimized packet reception. MAC computation and checking is now
5615 also more optimized. A lot previously duplicated code is now
5616 used as generic by both client and server.
5618 * Fixed key pair generation in clientutil.c
5620 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Added into lib/silccore/silcbufutil.[ch] new function;
5623 silc_buffer_realloc.
5625 * Moved generic packet sending/encryption functions to
5626 lib/silccore/silcpacket.[ch] from client and server. Some
5627 rewriting of the functions.
5629 * Moved all generic packet reception/decryption functions to
5630 lib/silccore/silcpacket.[ch] from client and server. The
5631 packet processing is now much cleaner in both client and server.
5632 These were major changes in both client and server.
5634 * Created many common functions in server to do packet sending.
5635 Previously code were duplicated a lot, this has been removed
5638 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Rewrote major parts of the ID cache system. Don't know
5641 whether it is better now or not but at least the API is more
5644 * Major rewrite on ID cache stuff on client because of the ID
5645 cache API changes. Added idlist.c to client.
5647 * Also major rewrite on ID cache stuff on server as well.
5648 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5649 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5650 in hand, instead they are all put into the ID cache system now.
5651 All server_idlist_* routines uses ID cache now instead of
5652 traversing its own lists (those lists does not exist anymore).
5653 SilcIDList though still exists. Also, SilcXXXEntry's are
5656 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Finally made the SKE implementation compliant to the protocol
5659 specification. All mp integers are now binary encoded as
5660 opposed being HEX encoded.
5662 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5665 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5666 functions: silc_[encode/decode]_pem. Also added function
5667 silc_encode_pem_file to PEM encode with newlines ('\n') for
5670 * SILC public keys are now encoded either PEM or binary. Same
5671 option is for private keys as well. By default private keys
5672 are binary encoded and public keys PEM encoded. Silly HEX
5673 encoding were removed.
5675 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5676 function to create fingerprints.
5678 * Fixed a bug in SHA1; does not change the original data anymore.
5680 * Partly implemented INFO command on client and server side.
5681 Fixed CLEAR command. Changes to SERVER command; show current
5682 server(s) when giving command without arguments. Added
5683 VERSION command to client.
5685 * Added check to server that unregistered connections cannot
5686 execute commands (unless it is specificly allowed).
5688 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Fixed screen refresh.
5692 * Fixed channel joining bug from client. On some circumstances
5693 client tried to join to a channel it had already joined.
5695 * Added public key verification process into client's protocol.c.
5696 The client now verifies the public key from user and saves
5697 it into ~./silc/serverkeys/ directory.
5699 Added into: clientutil.[ch]: silc_client_verify_server_key.
5701 * Changed SKE protocol's silc_ske_initiator_finish function
5702 to accept callback function that verifies the received public
5703 key. Removed old silc_ske_verify_public_key function.
5705 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5707 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5708 silc_pkcs_private_key[_data]_set.
5710 * Made the password and public authentication more cleaner in
5711 server's protocol.c.
5713 * Removed historic and obsolete protocol `channel_auth' from
5714 both client and server.
5716 * Removed wrong way of sending command status messages from
5717 server to client in server's command.c. The old way violated
5718 protocol specification.
5720 Changes to silccore/silccommand.[ch]: removed
5721 silc_command_encode_status_payload -> not needed anymore,
5722 changed silc_command_encode_payload_va to accept extra
5723 argument on variable argument list. The argument type must
5724 now be provided to the function. Also, added new function:
5725 silc_command_encode_reply_payload_va which is same as
5726 normal command_encode_payload_va except command status type
5727 is provided as extra argument.
5729 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5731 * Added ~./silc directory handling. The directory includes the
5732 public and private keys for the client.
5734 Added silc_client_check_silc_dir, silc_client_create_identifier
5735 and silc_client_load_keys.
5737 * Implemented SILC protocol compliant public key. Added public
5738 and private key saving to and loading from files.
5740 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5741 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5742 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5743 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5744 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5746 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5747 silc_pkcs_load_[public/private]_key.
5749 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added silc_server_get_route (route.[ch]) to get connection
5752 data for the fastest route for given ID.
5754 * Implemented INVITE command on client and server. The command
5755 were re-defined in the SILC Protocol Specification and the
5756 implementation now complies with the specification.
5758 * Implemented PING command on client and server.
5760 * Implemented NAMES command on client and server. The server side
5761 supports currently only normal server not router server yet.
5762 Some changes to NAMES definition in SILC protocol specification.
5764 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Implemented LEAVE command on client and server.
5768 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5769 again. This change was made to the protocol as well. Server
5770 should not violate the protocol specification anymore.
5772 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5775 was tested. SOCKS4 was not but should work anyway.
