17 * Added silc_pkcs_public_key_compare to compare two
18 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
20 * Check that the client who set the founder mode on the
21 channel is the same client that is giving the founder
22 mode to itself. It is done by comparing the saved public
23 key (it is saved even in the authentication is passphrase).
24 Affected file silcd/command.c.
26 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
28 * Do not process packet for disconnected socket connection.
29 Affected file lib/silccore/silcpacket.c.
31 * Process the DISCONNECT packet through scheduler in the
32 client library. Affected file lib/silcclient/client.c.
34 * Fixed the silc_client_packet_parse to not to increase
35 the packet sequence number if the conn->sock and the
36 current socket connection is not same. This can happen
37 for example during key agreement when the conn includes
38 multiple socket connections (listeners). Affected file
39 lib/silcclient/client.c.
41 * The sender of the file transfer request now provides also
42 the pointer (listener) for the key exchange protocol. If
43 the listener cannot be created then it sends empty key
44 agreement and lets the receiver provide the listener.
46 Added `local_ip' and `local_port' arguments to the
47 silc_client_file_send. If they are provided they are used,
48 if not then it will attempt to find local IP address, if
49 not found or bind fails then the remote client will provide
52 Affected files are lib/silcclient/client_ftp.c and
53 lib/silcclient/silcapi.h.
55 * Extended the FILE SEND command to support defining the

62 of the client's public key (if the proof of posession of the
63 corresponding private key is verified by the server).
64 Updated to the protocol specification.
66 * Added support of receiving the client's public key's
67 fingerprint in command reply in client library. Affected
68 file is lib/silcclient/command_reply.c, and
69 lib/silcclient/idlist.[ch].
71 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>

127 during SERVER_SIGNOFF, but invalidate it. This way we
128 preserve the WHOWAS info for the client. Affected file
131 * Fixed SERVER_SIGNOFF notify handling in the server. The
132 server is now able to process incoming SERVER_SIGNOFF notify
133 for a server that it doesn't even know about. It will remove
134 the clients provided in the notify. Affected file
135 silcd/packet_receive.c.
137 * Check for partial packet in data queue after every packet that
138 was found from the queue. Return and wait for more data if

164 available. It is used in padding generation. Affected file
165 lib/silccrypt/silcrng.[ch].
167 * All packets in client library are now processed synchronously.
168 Optimized packet processing a lot. Affected file
169 lib/silcclient/client.c.
171 * All server connection packets are processing synchronously
172 now in server, to optimize packet processing. Affected file
175 * Include files are installed now only in Toolkit distribution
176 if make install is given. Affected files: all Makefile.am's.
178 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
180 * Assure that silc_client_notify_by_server_resolve does not
181 resolve the client information multiple times. If it cannot
182 be found by the first it cannot be found at all. Affected
183 file lib/silcclient/client_notify.c.
185 * Fixed WHOWAS command reply calling. Affected file
186 lib/silcclient/command_reply.c.
188 * Removed all references to silc_idlist_get_client from the
189 Irssi SILC client since that call is internal call used by
190 the library. The Irssi SILC client will use now client
191 retrieval functions found in silcapi.h.
193 * Fixed a bug in resolving nickname info before sending
194 private message. It used freed memory. Affected file
195 irssi/src/silc/core/silc-servers.c.
197 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

216 * Added silc_net_localip to return local host's IP address.
217 Affected file lib/silcutil/silcnet.[ch].
219 * If key exchange or rekey protocol is active for a connection
220 parse all packets syncronously since there might be packets
221 in packet queue that we are not able to process without first
222 processing packets before them. Affected file silcd/server,
223 lib/silcclient/client.c.
225 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
226 whether library should continue processing the packet.
227 Affected file lib/silccore/silcpacket.h.

260 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
262 * Resolve the client info when received private message or
263 channel message for a client which nickname we don't know.
264 Affected files lib/silcclient/client_prvmsg.c and
265 lib/silcclient/client_channel.c.
267 * Do not crash in /KEY if client is not connected. Affected
268 file irssi/src/silc/core/silc-channels.c.
270 * Added SilcClientStatus field to the SilcClientEntry in the
271 lib/silcclient/idlist.h.
273 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
274 is incomplete and is being resolved, it won't be resolved
277 Make sure also that USERS command reply does not resolve
278 twice information. Affected file is
279 lib/silcclient/command_reply.c.
281 Make sure that silc_client_get_clients_by_list does not
282 resolve twice same information.
284 * Check for valid client->id in the silc_server_free_client_data.

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

310 * Redefined the SILC packet header to include the padding
311 length. Affected file lib/silccore/silcpacket.[ch].
313 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
314 length for maximum padding up to 128 bytes). Affected
315 file lib/silccore/silcpacket.h.
317 * Removed all backwards support for old 0.5.x MAC thingies.
318 The SILC packet header change makes it impossible to be
319 backwards compatible.
321 * Send the ENDING packet with timeout in the backup resuming
322 protocol. This is to assure that all routers has connected
323 to the primary router. Affected file silcd/server_backup.c.
325 * Changed the RNG to take the first IV from random data. It
326 used to take it from zero actually. Changed the RNG also
327 to use /dev/urandom during session. /dev/random is used
328 in initialization. Affected file lib/silccrypt/silcrng.[ch].
330 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
332 * Changed the SILC packet header to have the first two bytes
333 (the packet length) encrypted. Affected files aroung the
334 code tree, lib/silccore/silcpacket.[ch]. Removed the
335 SilcPacketCheckDecrypt callback. It is not needed anymore
336 since the silc_packet_receive_process will determine now
337 whether the packet is normal or special.
339 * Implemented the unidirectional MAC keys. Affected files
340 lib/silcske/silcske.c, silcd/protocol.c and
341 lib/silcclient/protocol.c.
343 * Implemented the packet sequence number to the MAC computation.
344 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
345 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
346 lib/silcclient/protocol.c.
348 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
350 * Allow backup router to announce servers. All servers
351 announced by backup router are added to the global list
352 automatically. Update hte server's socket to our primary
353 router also when backup router announces a server.
354 Affected file silcd/packet_receive.c.
356 * Do not update the client->router in the function
357 silc_server_udpate_clients_by_server if the client is on
358 global list. We might fail to find any specific server
359 for locally connected clients and local cell clients. They
360 should still use the `from' and not `to' as client->router.
361 This fixes backup router resuming protocol. Affected file
364 * Decrease channel statistics count only if the channel
365 deletion worked. Affected files are silcd/server.c and
368 * Added silc_server_update_servers_by_server to update origin
369 of all server entries. Used during backup router protocol.
370 Affected files silcd/server_util.[ch], silcd/server.c. and
371 silcd/backup_router.c.
373 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
374 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
375 silc_hmac_get_hash and silc_hmac_get_name. Affected file
376 lib/silccrypt/silchmac.c.
378 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
380 * Assure that router cannot reroute the same channel message
381 to the sender. Affected file silcd/packet_receive.c.
383 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
385 * Made better checks that the channel message is not sent
386 to the router it came from. Affected file is
387 silcd/packet_send.c. Fixed memory leak too.
389 * Announce informations for incoming router connection, but
390 only after checking if it is replaced by backup router.
391 Affected file silcd/packet_receive.c.
393 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
395 * Fixed the backup resuming protocol to work in multiple
396 router environment. Affected file silcd/server_backup.c.
398 * Route packet only to one router in the function
399 silc_server_packet_send_to_channel. Affected file is
402 * Fixed silc_server_send_notify_dest to set the broadcast
403 flag. Fixed the silc_server_send_notify_topic to actually
404 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
405 Affected file silcd/packet_send.c.
407 * Changed the SFTP Filesystem interface. Changed the
408 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
409 the filesystem operation function. The SilcSFTPFilesystem
410 is now a context that is allocated by all filesystem allocation
411 functions and it already includes the operations structure
412 and filesystem specific context. It is given as argument
413 now to the silc_sftp_server_start. This made the interface
414 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
415 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
417 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
419 * Changed the backup router adding and getting interfaces
420 in the server. The router that will be replaced by the
421 specified backup router is now sent as argument. Affected
422 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
425 * Added silc_net_addr2bin_ne to return the binary form of
426 the IP address in network byte order. Affected files
427 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
429 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Check for existing server ID in silc_server_new_server
432 and in silc_server_connect_to_router_final and remove the
433 old entry if it exists. Affected file silcd/packet_receive.c,

437 in upstream or downstream. Affected file is
440 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
442 * Wrote the definition of the backup resuming protocol to the
443 protocol specification.
445 * Removed one redundant channel key generation from normal
446 server during joining procedure. Removed one redundant
447 channel key sending from server to router during joining
448 procedure. Affected file silcd/command.c.
450 * Made minor bugfixes to the backup router resuming protocol.
451 Affected file silcd/server_backup.c, server.c.
453 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
455 * Added --disable-asm configuration option. Affected files
456 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
459 * Implemented the backup resuming protocol that is used to
460 resume the primary router position in the cell after the
461 primary router comes back online. Affected files
462 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
463 and silcd/server_util.[ch].
465 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
467 * Sleep two (2) seconds after sending QUIT command to server.
468 Affected file lib/silcclient/command.c.
470 * Assure that if outgoing data buffer is pending do not force
471 send any data. Affected file silcd/packet_send.c.
473 * Assure that if outgoing data buffer is pending do not force
474 send any data. Affected file lib/silcclient/client.c.
476 * Implemented the backup router support when the primary router
477 goes down. The servers and routers can now use the backup
478 router as new primary router without loosing connectivity.
480 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
482 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
483 in the server to indicate disabled entry. All data read
484 from the connection will be ignored and no data is sent
485 for entry that is disabled. Affected files are
486 silcd/idlist.h, silcd/server.c.
488 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
490 * Created SFTP client and server test programs in the
491 lib/silcsftp/tests directory.
493 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
495 * Implemented memory filesystem (virtual filesystem) for
496 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
499 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Implemented the SFTP (SSH File Transfer Protocol) to the
502 lib/silcsftp. It includes SFTP client and SFTP server
505 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Moved lib/silccore/silcprotocol.[ch] to the
508 lib/silcutil library.
510 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
511 take variable argument list pointer as argument. Affected
512 file lib/silcutil/silcbuffmt.[ch].
514 * Added silc_buffer_set function that is used to set data
515 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
516 Affected file lib/silcutil/silcbuffer.h.
518 * Changed various routines in the core library to use the new
519 silc_buffer_set instead of allocating new buffer only for
522 * Added 64-bit value formatting and unformatting support to the
523 silc_buffer_[un]format routines. Affected file is
524 lib/silcutil/silcbuffmt.[ch].
526 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
527 to includes/bitmove.h.
529 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
531 * Fixed channel user mode saving in client library. Affected
532 file lib/silcclient/command[_reply].c.
534 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
536 * Defined the file transfer to the SILC Protocol. Added
537 new packet type SILC_PACKET_FTP and defined File Transfer
538 Payload. The mandatory file transfer protocol is SFTP
539 (SSH File Transfer Protocol). Affected file in addition
540 of the internet draft is lib/silccore/silcpacket.h.
542 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
543 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
544 is used as part of backup router protocol when the primary
545 router of the cell is back online and wishes to resume
546 the position as primary router.
548 * Redefined the MAC generation keys in the protocol. The
549 same key is not used anymore in both direction. Both
550 direction will now use different keys for sending and
551 receiving. This fixes a potential security flaw. This
552 change causes incompatibilities in the protocol.
554 * Redefined also the MAC computation from the packet.
555 An packet sequence number is now added to the MAC
556 computation. This prevents possible replay attacks against
557 the protocol. This change too causes incompatibilities
560 Added `sequence' field to the SilcPacketContext to hold
561 the current sequence number for the packet.
563 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
565 * Added `created' field to the SilcIDListData in the file
566 silcd/idlist.h to indicate the time when the entry was
569 * Added `created' field to the SilcChannelEntry too. Affected
572 * Added `creation_time' aguments to all the announcement functions
573 in the server. If it is provided then only the entries that
574 was created after the provided time frame are actually
575 announced. Affected file silcd/server.[ch].
577 * The protocol says that the Channel ID's IP address must be
578 based on the router's IP address. Added check for this in
579 the silc_server_new_channel when processing incoming New Channel
580 Payload. Affected file silcd/packet_receive.c.
582 * Print out the correct version with --version in SILC client.
583 Affected file irssi/src/silc/core/silc-core.c.
585 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
587 * Fixed WHOWAS command to check for completnes of the client
588 entry always, not just when the command is coming from client.
589 Affected file silcd/command.c.
591 * Added new function silc_server_packet_queue_purge to purge the
592 outgoing data queue to the network. After the function returns
593 it is guaranteed that the outgoing packet queue is empty.
594 Affected file silcd/packet_send.[ch].
596 * Purge the outgoing packet queue in the rekey protocol's final
597 callback to assure that all rekey packets go to the network
598 before quitting the protocol. Affected file silcd/server.c.
600 * Added silc_client_packet_queue_parse as similar function as
601 in server to the client library. The affected file is
602 lib/silcclient/client.c.
604 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
606 * Splitted silcd/server.c and created silcd/server_util.[ch]
607 for utility functions.
609 * Added new socket flag SILC_SF_DISABLED to indicate that the
610 connection is open but nothing can be sent to or received from
611 the connection. Affected file lib/silcutil/silsockconn.[ch].
612 The checking for disabled socket is checked in the low level
613 silc_socket_write and silc_socket_read functions.
615 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
617 * Allow only nicknames and channel names that fits into the
618 7-bit unsigned char ASCII set. Affected file silcd/command.c.
620 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
622 * When processing JOIN command reply in server check that if
623 the channel exists in our global list we'll move it the local
624 list. Affected file silcd/command_reply.c.
626 * Fixed the check whether client is joined on the channel already
627 in JOIN command. Affected file lib/silcclient/command.c.
629 * Fixed the JOIN command reply to check whether the channel
630 already exists. Affected file lib/silcclient/command_reply.c.
632 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Added silc_ske_status_string to map the SKE error numbers
635 to readable strings. The affected files are
636 lib/silcske/silcske[_status].[ch].
638 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
640 * Do not show the private channels on the WHOIS channel list
641 as it is not allowed by the protocol. The affected file is
644 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
646 * Assure that the packet length digged from the actual packet
647 is something sensible in the silc_packet_decrypt_rest_special
648 in lib/silccrypt/silcpacket.c.
650 * Free and NULL the allocated pointer in silc_hmac_alloc if
651 the HMAC allocation fails. The affected file is
652 lib/silccrypt/silchmac.c.
654 * Print the selected security properties to the log files in
655 the server. Affected file silcd/protocol.c.
657 * Add SKE's reference counter even if calling the completion
658 callback manually. Otherwise it goes negative, although it
659 does not cause any problems. The affected file is
660 lib/silcske/silcske.c.
662 * Remove the client entry with short timeout after giving the
663 KILL command. Affected file lib/silcclient/command.c.
665 * Fixed to send error reply in WHOIS and IDENTIFY commands in
666 case all found clients are already disconnected (WHOWAS would
667 found them) in the server. Affected file silcd/command.c.
669 * Update the last_receive (time of last data received) to be
670 updated only when received private or channel message so that
671 the idle time showed in WHOIS makes more sense.
673 * Added boolean field `valid' in to the SilcClientEntry in the
674 client library to indicate whether the entry is valid or not.
675 This fixes the nickname change bug on channel when changing
676 the nickname to be same than the old (like nick to Nick) the
677 nickname formatter doesn't set the new nick anymore to Nick@host.
678 Affected file lib/silcclient/idlist.[ch].
680 * Now actually fixed the nickname changing on disconnection.
681 Added new function silc_change_nick to the Irssi SILC Client.
682 Affected file irssi/src/silc/core/client_ops.c,
683 irssi/src/silc/core/silc-nicklist.[ch].
685 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
687 * Check that the public key exists in the GETKEY command before
688 trying to encode it. Affected file silcd/command.c.
690 * Print some notifications on received public keys with GETKEY
691 command in the Irssi SILC Client. Affected files are
692 irssi/src/fe-common/silc/module-formats.[ch],
693 irssi/src/silc/core/client_ops.c.
695 * Use IDENTIFY command to resolve the server information in the
696 GETKEY command instead of INFO command. Affected file
697 lib/silcclient/command.c.
699 * All command reply functions in the client library now calls
700 the pending command reply callbacks even if an error has
701 occurred. The server has done this a long time and now it was
702 time to move the client library to this as well. Now all
703 errors can be delivered back to the pending command reply
704 callbacks if necessary. Affected files are
705 lib/silcclient/command[_reply].[ch].
707 * Change the nickname on disconnection back to the username
708 because in reconnect the server will enforce it to it anyway.
709 Affected file irssi/src/silc/core/silc-servers.c.
711 * Fixed a config file parsing bug in the Irssi SILC client.
712 Affected file irssi/src/silc/core/clientconfig.c.
714 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
716 * When printing the channel mode on JOIN, verify that the
717 channel key and channel's HMAC are valid. Affected file
718 irssi/src/silc/core/client_ops.c.
720 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
722 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
723 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
724 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
726 * Removed channel key rekey task deleting from the function
727 silc_server_save_channel_key. Affected file silcd/server.c.
728 Added explicit timeout task context instead that is used to
729 delete the task if we are registering a new task before the
730 new task has elapsed.
732 * When channel key rekey occurs the client library now saves
733 the old channel key for a short period of time (10 seconds) and
734 is able to use it in case some is still sending channel
735 messages encrypted with the old key after the rekey. Affected
736 file lib/silcclient/[idlist.h|client_channel.c].
738 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
740 * Added check to the silc_server_new_id_real to not accept
741 new ID if it is the sender's own ID. Affected file is
742 silcd/packet_receive.c.
744 * Assure that we do not announce ourself or the one we've
745 sending our announcements when we're router and are announcing
746 servers to our primary router. Affected file silcd/server.c.
748 * Fixed silc_server_command_identify_check_client to assemble
749 correct WHOIS packet. It send corrupted WHOIS packet and
750 caused problem with router to router connections. Affected
751 file silcd/command.c.
753 Fixed also silc_server_command_whois_check the same way
754 as for the IDENTIFY command.
756 * Added new SilcIDListStatus to the server in the SilcIDListData
757 structure. The status now includes the current status of
758 the entry (like registered, resolved etc.). Affected file
759 silcd/idlist.[ch]. Defined a bunch of different status types
760 as well. This replaced the old boolean registered field as well.
762 Added resolve_cmd_ident field to the SilcClientEntry structure
763 too so that if the entry is for example being resolved so
764 another command may attach to the same pending command reply
765 without requiring to resolve the same entry again. This concept
766 should optimize the WHOIS and the IDENTIFY resolving under
767 heavy load by taking away unnecessary resolving for entries
768 that are being resolved already.
770 Added support for adding multiple pending commands for one
771 command idenfier. Affected file silcd/command[_reply].[ch].
773 * Fixed WHOIS and IDENTIFY save to remove the cache entry
774 before deleting the data. Otherwise the hash table will have
775 freed data in comparison functions. Affected file is
776 silcd/command_reply.c.
778 * Fixed silc_idlist_replace_client_id to add the new entry to
779 the cache with NULL nickname. Otherwise there will be invalid
780 memory as the nickname after the nickname is freed. Affected
781 file silcd/packet_receive.c.
783 * Fixed the silc_idlist_get_clients_by_hash. The entries was
784 saved into wrong slots because the previous number of entries
785 was not taken into account. Affected file silcd/idlist.c.
786 Fixed same thing in silc_idlist_get_clients_by_nickname too.
788 * If we are router and we receive JOIN notify to a channel that
789 does not have any users then notified client is marked as the
790 channel founder, as it is it. The affected file is
791 silcd/packet_receive.c
793 * Added to the extended hash table API's table_del_*ext functions
794 the destructor as argument too, so that the caller can decide
795 which destructor to use or whether to use destructor at all.
796 Affected file lib/silcutil/silchashtable.[ch].
798 * Fixed ID Cache purging. It actually deleted the entries from
799 the hash table after the data was freed. The hash table ended
800 up comparing freed memory. The affected file is
801 lib/silccore/silcidcache.c.
803 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Fixed Irssi SILC client's KILL command's HELP syntax.
807 * The USERS command now resolves the detailed user information
808 if the userinfo field is missing. Affected file is
809 lib/silcclient/command_reply.c.
811 * Do not print error in silc_file_read if the read file does
812 not exist. Just silently return NULL. Affected file is
813 lib/silcutil/silcutil.c.
815 * Fixed the silc_log_output to not wine about NULL filename
816 and to not create some bogus " " filename. Affected file is
817 lib/silcutil/silclog.c.
819 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Fixed various printing bugs on the user interface in the
822 Irssi SILC Client. Minor changes that were forgotten from
825 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Fixed the configure.in.pre and the compilation and distribution
828 environment to support the new autoconf 2.52. That version is
829 now required to compile the CVS trunk.
831 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
833 * Renamed function silc_parse_nickname to silc_parse_userfqdn
834 to generally parse user@fqdn format strings. Affected file
835 lib/silcutil/silcutil.c.
837 * Added nickname_format and nickname_force_format fields to the
838 SilcClientParams structure. The first one defines the format
839 for the nicknames that the library will enforce if the receives
840 multiple same nicknames. The second one is boolean value and
841 can be used to force the library to always enforce the format
842 to the nicknames regardles whether there are multiple nicknames
843 or not. This configurable formatting was employed to flexibly
844 support accessing multiple nicknames from the user interface.
845 The userinterface can now set the nicknames to what ever format
846 they prefer. Affected file lib/silcclient/silcapi.h.
848 Added function silc_client_nickname_format to the file
849 lib/silcclient/idlist.c. It performs the nickname formatting.
851 Added new field `hostname´ to the SilcClientEntry context.
852 It holds the hostname of the client. Affected file is
853 lib/silcclient/idlist.h.
855 * Irssi SILC Client sets the nicknames in nick@hostn format.
856 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
857 irssi/src/silc/core/silc-core.c.
859 The WHOIS printing now also shows both the real nickname and
860 the formatted nickname so that user knows how to access the
861 user if there are multiple same nicknames cached. Affected
862 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
863 printing formatting too to take the hostname now as a separate
864 argument. The Affected file is
865 irssi/src/fe-common/silc/modules-formats.[ch].
867 * Changed the silc_client_get_clients_local to accept the formatted
868 nickname as argument. It accepts the real nickname too but the
869 formatted nickname can be used to find the true entry from
870 multiple entries. Affected file lib/silcclient/silcapi.h and
871 lib/silcclient/idlist.c.
873 * Added nickname_format_parse field to the SilcClientParams.
874 It is a callback function provided by the application to parse
875 the nickname out of the formatted nickname string. The library
876 calls it to get the nickname from the formatted string. Since
877 the application generally knows better the format of the nickname
878 string it parses it instead of the library, even though library
879 encodes the formatted string. If the callback function is not
880 provided then the library will use the string as is. The
881 affected file is lib/silcclient/silcapi.h.
883 * All the nickname strings passed to the client library in
884 commands are now expected to be formatted nickname strings.
885 If the command does not support the formatted nickname string
886 it will assume that the sent string is the actual nickname.
887 Affected file lib/silcclient/command.c.
889 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Added public key authentication support to OPER and SILCOPER
892 commands in the client library. Affected file is
893 lib/silcclient/command.c.
895 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Changed the get_auth_methdod client operation to be asynchronous.
898 It can be async if the application resolves the authentication
899 method from the server during the negotiation. Added new
900 SilcGetAuthMeth completion callback that the application will
901 call after resolving the authentication method.
903 Added function silc_client_request_authentication_method that
904 the application can use to resolve the authentication method
905 from the server. Added also SilcConnectionAuthRequest callback
906 that the library will call after the server has replied. The
907 application can call this function if it does not know the
908 current authentication method.
910 Affected files are lib/silcclient/client.c and
911 lib/silcclient/silcapi.h.
913 * The Irssi SILC client now automatically resolves the authentication
914 method incase any configuration information is not present (and
915 currently there never is). The affected file is
916 irssi/src/silc/core/client_ops.c.
918 * Fixed public key authentication from the client library.
919 Affected file lib/silcclient/protocol.c. Changed also the
920 protocol specification about the public key authentication in
921 the connection authentication protocol. The actual data to be
922 signed is now computed with a hash function before signing.
924 * Fixed the public key authentication from the server as well.
925 Affected file silcd/protocol.c.
927 * Removed the mlock()'s from the memory allocation routines.
928 Affected file lib/silcutil/silcmemory.c. The ./configure does
929 not check anymore for the mlock(). Affected file is
932 * Fixed USERS command in server to allow the execution of the
933 command for private and secret channels if the client sending
934 the command is on the channel. Affected file silcd/command.c.
936 * Fixed silc_client_get_clients_local to return the clients
937 count correctly. It could return wrong value. Affected file
938 lib/silcclient/idlist.c.
940 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
942 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
943 types. The assembler optimizations seemed not to like 64-bit
944 data types. The assmebler optimizations thus are now enabled
945 also for BSD systems as opposed to only enable them for Linux.
947 * Do not check for threads at all on BSD systems. Affected
948 file configure.in.pre.
950 * Removed -n and -h options from the Irssi SILC Client since
951 they are not used in silc.
953 * Fixed the prime generation to assure that the first digit
954 of the generated random number is not zero since our conversion
955 routines does not like number strings that starts with zero
956 digit. If zero digit is seen the random number is regenerated.
957 This caused some corrupted RSA keys when the zero first digit
958 was met. Affected file lib/silcmath/silcprimegen.c.
960 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
962 * Fixed WIN32 configuration in the ./configure script.
963 Fixed to include xti.h on environments that has it.
964 Patches by Carsten Ilchmann and andrew.
966 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
968 * Changed the silc_id_create_client_id to be collision
969 resistant. It is now assured that there cannot be created
970 two same client ID's. I suspect that some weird bugs in
971 the server were actually caused by duplicate Client IDs.
972 Affected file silcd/serverid.[ch]. A router receiving
973 new ID now also assures and informs the sending server
974 if the ID caused collision.
976 * Changed the silc_id_create_channel_id to also assure that
977 there are no collisions.
979 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Statement about ignoring the Mutual Authentication flag when
982 performing rekey with PFS was a bit misleading. It is ignored
983 if it was set in the initial negotiation, it cannot be even
984 set in the rekey. Fixed in the ke-auth draft. Started the
985 new versions of the protocol drafts in the doc/.
987 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
989 * Fixed a bug in silc_client_command_identify_save when saving
990 new channel information. The channel name was no duplicated
991 and caused crash on exit. Affected file is
992 lib/silcclient/command_reply.c.
994 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
996 * Fixed the getkey command handling in the server. Send just
997 empty OK reply to the sender if the key could not be fetched
998 (but everything else was ok, like the key just was not available).
999 Changed the public key parameter to optional in the protocol
1000 specs so that empty OK reply can be sent. Affected file
1003 Added a message to Irssi SILC client to tell to user if the
1004 server did not return a public key.
1006 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1008 * Fixed a channel key regeneration bug. It registered new
1009 timeout tasks exponentially until all system resources were
1010 used. Affected file silcd/server.c.
1012 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Added the SILC Document generator to the scripts/silcdoc.
1015 It can be used to generate the Toolkit Reference Manual out
1016 of the source tree. Internally it will also use the RoboDoc
1017 generator now imported in util/robodoc.
1019 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1021 * Added couple of return's in rekey protocol if error orccurred
1022 during the protocol. The execution must be terminated.
1023 Affected file silcd/protocol.c. Also, terminate the protocol
1024 always with timeout.
1026 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * The client's Client ID was created initally from the wrong
1029 nickname (it could have been in format nick@host) in the
1030 silc_server_new_client. Affected file silcd/packet_receive.c
1032 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Added some SILC_LOG_ERROR's to various error conditions
1035 if client could not be added to ID cache. Affected files
1036 silcd/packet_receive.c and silcd/server.c.
1038 * When client's sock->user_data is freed, NULL also the
1039 client->router and client->connection pointers. Added check
1040 for these pointers being NULL to various places around the
1041 code. Affected file silcd/server.c.
1043 * Added client->data.registered == TRUE checks to various
1044 places around the code to assure that unregistered client's
1045 are not handled when it is not allowed. Affected file
1048 * Added `bool registered' fields to all
1049 silc_idlist_[server|client]_get_* routines to indicate whether
1050 the fetched client needs to be registered or not. Affected
1051 file silcd/idlist.[ch].
1053 * Add your own entry as registered to the ID cache in the
1054 server. Affected file server.c.
1056 * Fixed a bug in silc_server_new_server. The SilcServer was
1057 set as the new server's context instead of SilcServerEntry.
1058 This naturally caused some weird bugs.
1060 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Do not delete the channel rekey task when adding it
1063 for in silc_server_create_channel_key.
1065 * Changed the silc_server_create_channel_key to return
1066 TRUE or FALSE to indicate the success of the channel key
1069 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * Fixed MSVC++ project files and added missing files to
1072 Makefiles under win32/.
1074 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1076 * Do not add TCP_NODELAY flag if the operating system
1077 does not have it defined. Affected files are
1078 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1080 * Fixed buffer overflow from Irssi SILC Client. Affected
1081 file irssi/src/fe-common/core/themes.c.
1083 * Fixed double free in client library in the file
1084 lib/silcclient/client.c when disconnecting from server.
1086 * Applied double free patch from cras to Irssi SILC client.
1087 Affected files irssi/src/core/[modules/expandos].c
1089 * Fixed the disconnection handling to Irssi SILC Client.
1090 The application must call silc_client_close_connection
1091 in ops->connect client operation in case of failure of
1092 the connection. Affected file is
1093 irssi/src/silc/core/client_ops.c.
1095 * Do not set sock->protocol to NULL in the function
1096 silc_client_close_connection after executing the protocol's
1097 final callback since the sock might not be valid anymore.
1098 Affected file lib/silcclient/client.c.
1100 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1102 * Do not enable SILC_THREADS if the linking with libpthread
1103 did not happen. Affected file configure.in.pre.
1105 * Added notion to protocol specification that server must
1106 verify the sent authentication payload with CMODE when
1107 setting the channel founder key. Implemented it to the
1108 server. Affected file silcd/command.c.
1110 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * Added _EXTRA_DIST SILC distribution variable to the
1113 distributions file. It is used to conditionally add extra
1114 files or directories to the specific distribution. Affected
1115 files ./prepare, Makefile.am.pre and distributions.
1117 Removed the `_' from the start of the distribution names.
1120 * Added README.WIN32 for instructions to compile the Toolkit
1123 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1125 * Fixed a double free in disconnection in the server. Affected
1126 file is silcd/server.c.
1128 * Fixed the lib/silcske/groups.c to work now also with GMP
1129 MP library. The string conversion did not work when using
1130 specific base and the base is indicated in the string as well.
1132 * Created win32/ directory which now includes MSVC++ specific
1133 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1134 It will appear only in the toolkit distribution
1136 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1138 * Changed the key material distribution function in case when
1139 the hash output is too short. The data is now concatenated
1140 a bit differently than it used to. Made the change to the
1141 SKE protocol specification.
1143 * Added better GMP detection to configure.in.pre. A patch
1146 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1148 * Fixed a minor bug in SKE that might cause some problem on
1149 some platforms. Affected file lib/silcske/silcske.c.
1151 * Added the cookie checking for initiator in the SKE. It checks
1152 that the responder returns the sent cookie unmodified. The
1153 affected file is lib/silcske/silcske.c. Added new SKE
1154 error type INVALID_COOKIE that can be sent during the
1155 negotiation. Fixed some memory leaks as well.
1157 * Added the "invalid cookie" error message to Irssi SILC client's
1160 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Added `task_max' field to the SilcClientParams to indicate
1163 the maximum tasks the scheduler can handle. If set to zero,
1164 default values are used. Affected file lib/silcclient/silcapi.h.
1166 * Fixed memory leaks in silc_client_close_connection. Affected
1167 file lib/silcclient/client.c.
1169 * Added silc_client_del_client_entry to client library to free
1170 all memory of given client entry. Affected file is
1171 lib/silcclient/idlist.[ch].
1173 * Added new functions silc_client_del_channel and
1174 silc_client_del_server to delete channel and server entries.
1175 Affected file lib/silcclient/[silcapi.h/idlist.c].
1177 * Removed silc_client_del_client_by_id from silcapi.h.
1179 * Fixed the INFO command to return the server's own info
1180 correctly when querying by Server ID. Affected file is
1183 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Removed the non-blocking settings in WIN32 code in the
1186 silc_sock_[read/write] and added SleepEx instead. Affected
1187 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1188 of input data is now checked with FIONREAD and ioctlsocket.
1190 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1192 * Call silc_schedule_task_del_by_context in the
1193 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1194 Affected file lib/silccore/silcprotocol.c.
1196 * Call silc_protocol_cancel for active protocols in the
1197 silc_server_close_connection if the funtion
1198 silc_server_free_sock_user_data has not been called.
1199 Affected file silcd/server.c.
1201 * Generic tasks cannot be deleted using the del_by_fd
1202 task deleting function since generic tasks does not match
1203 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1205 * Added a notion to SILCOPER help file that the SILCOPER works
1206 only on router server, not on normal server.
1208 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1210 * Added for WIN32 support for the new scheduler as well.
1211 Affected file lib/silcutil/win32/silcwin32schedule.c.
1213 * Fixed the SHA1 implementation to work on various platforms.
1215 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1217 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1218 API. It is part of the scheduler now. Everything else is
1219 as previously but some functions has changed their names.
1220 Checkout the lib/silcutil/silcschedule.h for the interface.
1221 Updated all applications to use the new interface. Affected
1222 files are lib/silcutil/silcschedule.[ch].
1224 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Found a bug in the SKE implementation. The HASH value,
1227 specified by the protocol, was not computed correctly. The
1228 public key of the responder was not added to the computation
1229 even though it is mandatory. Affected file lib/silcske/silcske.c.
1230 This unfortunately causes incompatibilities with older
1231 clients and servers.
1233 * Added WIN32 specific network init and uninit functions:
1234 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1235 the Winsock2. Affected file lib/silcutil/silcnet.h and
1236 lib/silcutil/win32/silcwin32net.c.
1238 * Set the socket always to nonblocking mode on WIN32 after
1239 reading data or writing data. Affected file is
1240 lib/silcutil/win32/silcwin32sockconn.c.
1242 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Fixed various compilation problems under WIN32. Affected
1245 files lib/silcutil/win32/silcwin32thread.c and
1246 lib/silcutil/win32/silcwin32schedule.c.
1248 * Removed all _internal.h #includes from public header
1249 files. Internal headers must never be included from
1252 Removed also the lib/silcske/payload_internal.h file.
1254 * All include files that may be needed (public and some others
1255 included by the public headers) by application developers are
1256 now copied to the ./includes directory. It does not copy any
1257 internal headers. Affected file Makefile.defines.pre and all
1258 Makefile.am's under lib/ and subdirs.
1260 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1262 * Do not change the ~/.silc directory's permissions automatically.
1263 Affected file irssi/src/silc/core/clientutil.c.
1265 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1267 * Do not cancel the protocol in silc_server_close_connection
1268 it might cause recursion. Now cancelled in the function
1269 silc_server_free_sock_user_data. Affected file silcd/server.c.
1271 * Fixed the silc_server_remove_clients_by_server to regenerate
1272 the channel keys correctly finally. Added also new function
1273 silc_server_remove_clients_channels to actually do it.
1274 Affected file silcd/server.c.
1276 * Fixed the silc_server_new_channel to not crash by giving
1277 wrong router to the new channel. Affected file is
1278 silcd/packet_receive.c.
1280 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1282 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1283 which is given as argument to the silc_client_alloc now.
1284 It can be used to configure the client and set various parameters
1285 that affect the function of the client.
1287 * The USERS command in server did not check whether the channel
1288 is private or secret. Affected file silcd/command.c.
1290 * Added new argument to the USERS command in protocol specification.
1291 The USERS command now can take the channel name as argument
1292 as well. Added support for this in client and server and
1293 updated the protocol specs.
1295 * Completed the GETKEY command in client. It can be now used
1296 to fetch also servers public key not only some clients.
1297 Affected files lib/silcclient/command[_reply].c.
1299 * Added silc_client_get_server to return server entry by the
1300 server name. Affected files lib/silcclient/silcapi.h and
1303 * Redefined the IDENTIFY command in protocol specification to be
1304 more generic. It now can be used to query information about
1305 any entity in the SILC Network, including clients, servers and
1306 channels. The query may be based either the entity's name
1307 or the ID. Added support for this in both client and server.
1309 Affected files silcd/command.c and lib/silcclient/command.c
1310 and command_reply.c.
1312 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1313 the _from_client and _from_server functions. Affected file
1316 * Added silc_client_get_channel_by_id_resolve to the file
1317 lib/silcclient/silcapi.h to resolve channel information by
1318 its ID. Added also silc_client_get_channel_by_id that
1319 does not resolve it from the server.
1321 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * Added SilcServerEntry context into the client library
1324 to represent one server. The INFO command now allocates
1325 these to save the resolved server info. For now on the
1326 client library will also keep information about servers,
1327 connected and resolved with INFO.
1329 The INFO command now allocates the SilcServerEntry context
1330 and saves the server info there. The COMMAND_REPLY in
1331 the INFO now returns the parameters to application in
1332 same order as defined in the protocol specification.
1334 The entries are cached in the client->server_cache.
1336 * The INFO command is now issued after received the Client ID
1337 from the server. Affected file lib/silcclient/client.c.
1339 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1340 to the application as the mode changer might be server.
1341 It is guaranteed that NULL is not returned anymore to the
1342 application. Affected file lib/silcclient/client_notify.c.
1344 The ID Type is now also passed to the application so that
1345 it can check whether the returned entry is SilcClientEntry
1348 Added new function silc_client_get_server_by_id to return
1349 the server entry by ID. Affected files are the
1350 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1352 * Do not create the channel in the Irssi SILC Client when issuing
1353 the JOIN command but when received the sucessful JOIN command
1354 reply. Otherwise the channel might get created even though we
1355 could not join it. The Affected file is
1356 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1358 * Fixed a channel joining bug in router. The router must also
1359 check the channel modes, invite and ban lists etc. when serving
1360 the JOIN command sent by normal server. Affected file is
1361 silcd/command.c. The router now resolves the client's
1362 information from the server who sent the JOIN command if it
1363 does not know it, and processes the JOIN command only after
1366 * Changed the SilcCommandCb to take new argument; void *context2.
1367 Affected file lib/silccore/silccommand.h
1369 The second argument in the command callbacks in the server now
1370 includes the SilcServerCommandReplyContext if the command was
1371 called as pending command callback from the command reply.
1372 Otherwise it is NULL. When called as pending the status of the
1373 command reply will be checked and if it was erronous the
1374 error will be sent to the original sender of the command.
1375 This way the client always receives the error messages even
1376 though the server was actually the one who received the error
1377 when it resent the command to router, for example. Affected
1378 files silcd/command[_reply].[ch].
1380 * Fixed sending WHOWAS command's error message to client if
1381 the requested client could not be found. It was missing.
1384 * Changed the CMODE and CUMODE commands reply arguments in the
1385 protocol specification. The Channel ID is now sent in both
1386 of the commands to identify the channel. Implemented this
1387 new feature to the client and server. Affected files
1388 lib/silcclient/command_reply.c and silcd/command.c.
1390 * Made better checks for invite and ban lists in the JOIN
1391 command in server. Affected file silcd/command.c.
1393 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1395 * The server now performs the incoming host IP/DNS lookup
1396 using the silc_socket_host_lookup and thus does not block
1397 the server anymore. Affected file silcd/server.c.
1399 * Completed the multi-thread support for SILC Scheduler in
1400 the lib/silcutil/silcschedule.c.
1402 * Fixed the configure.in.pre to detect the pthread correctly
1405 * Fixed a deadlock in silc_task_queue_wakeup in the file
1406 lib/silcutil/silctask.c.
1408 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1410 * Added new function silc_schedule_wakeup that is used in
1411 multi-threaded environment to wakeup the main thread's
1412 schduler. It needs to be used when a thread adds a new task
1413 or removes a task from task queues. After waking up, the
1414 scheduler will detect the task queue changes. If threads
1415 support is not compiled in this function has no effect.
1416 Implemented the wakeup mechanism to both Unix and WIN32
1417 systems. Affected files are lib/silcutil/silcschedule.[ch],
1418 lib/silcutil/unix/silcunixschedule.c and the
1419 lib/silcutil/win32/silcwin32schedule.c.
1421 * Added new function silc_task_queue_wakeup to wakeup the
1422 scheduler by the specified task queue. Affected file
1423 lib/silcutil/silctask.[ch].
1425 * The silc_socket_host_lookup_start now wakes up the scheduler
1426 after adding the timeout task. Affected file is
1427 lib/silcutil/silcsockconn.c.
1429 * The silc_socket_host_lookup is synchronous now if the threads
1430 support is not compiled in. However, the callback is still
1431 called asyncronously through the scheduler, anyway. Affected
1432 file lib/silcutil/silcsockconn.c.
1434 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Added new function silc_socket_host_lookup to perform
1437 asynchronous IP and FQDN lookups for the socket connection.
1438 Affected files lib/silcutil/silcsockconn.[ch].
1440 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1443 that may or may not compile the mutex support in.
1445 Changed the silc_mutex_alloc interface. It allocates the
1446 mutex now to the sent pointer and returns TRUE or FALSE.
1448 Affected file lib/silcutil/silcmutex.h.
1450 * Wrote the SILC Task Queue interface to support multi-threads.
1451 Affected file lib/silcutil/silctask.[ch].
1453 * Wrote the SILC Scheduler to support multi-threads. Affected
1454 file lib/silcutil/silcschedule.c.
1456 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1458 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1459 in lib/silcutil/win32/.
1461 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Defined SILC Mutex API and SILC Thread API and implemented
1464 them for Unix. Affected files are
1465 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1466 lib/silcutil/unix/silcunixmutex.c and
1467 lib/silcutil/unix/silcunixthread.c.
1469 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1471 * Fixed the silc_server_remove_clients_by_server's channel
1472 key re-generation. The hash table handling was incorrect
1473 and would not work with many channels. Affected file is
1476 * Fixed some memory leaks around the server code.
1478 * Rewrote the silc_server_get_users_on_channel to support IPv6
1479 based Client ID's. Affected file silcd/server.c.
1481 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1482 specification. However, a separate document must be written
1483 to define the detailed signing procedure and the payload
1484 associated with the flag. Defined the flag to the
1485 lib/silccore/silcchannel.h as well.
1487 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Changed the dynamic tables to static size tables in the
1490 lib/silccrypt/silchmac.c.
1492 * Removed GCC dependencies from the code. A patch by cras.
1494 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Do not show the error "Error receiving packet bla bla"
1497 in server if it really was not an error (-2 means that reading
1498 is pending). Affected file silcd/server.c.
1500 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Fixed a possible crash in silc_server_remove_clients_by_server
1503 in silcd/server.c. Fixed there also some memory leaks.
1505 * Fixed the silc_idlist_replace_client_id. It could replace
1506 wrong key in the hash table. Affected file silcd/idlist.c.
1508 * Do not check whether there are global users on the channel
1509 if the channel->global_users is FALSE. Affected functions
1510 silc_server_remove_from_one_channel and
1511 silc_server_remove_from_channels in silcd/server.c. Also,
1512 do not check if the removed client is local as we can be
1513 sure that global client was not removed from the channel
1514 and checking for global users is not needed.
1516 * The silc_server_remove_clients_by_server now re-generates
1517 the channel keys correctly for those channels that had
1518 clients removed from them. Affected file silcd/server.c.
1520 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1522 * Found the reason of random crashes in the server. We weren't
1523 ignoring the SIGPIPE signal (which can be sent in write())
1524 and it crashed the server. Affected file silcd/silcd.c.
1526 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1528 * Assure that sock->user_data is not NULL in the function
1529 silc_server_packet_send in silcd/packet_send.c.
1531 * Disconnect the remote connection if it could not be added
1532 to any ID lists in the server. The affected file is
1535 * Check in silc_server_packet_send[_real/dest] that the
1536 socket is not disconnecting and ignore the data if it is.
1537 Affected file silcd/packet_send.c.
1539 * Define inline to __inline on native WIN32 compilation.
1540 Affected file includes/silcwin32.h.
1542 * Added some explicit type casts for inline code since MSVC
1543 require them. Affected files lib/silcutil/silcbuffer.h,
1544 lib/trq/silcdlist.h and lib/trq/silclist.h.
1546 * Print warning in log files from now on if the packet
1547 decryption fails. Affected file silcd/server.c.
1549 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * Changed the `say' client operation's interface to accept
1552 new `type' argument to indicate the type of the message sent
1553 by the library. The application may filter the library's
1554 messages according the type. The affected file is the
1555 lib/silcclient/silcapi.h.
1557 * Added two new functions to lib/silcclient/silcapi.h:
1558 silc_client_del_client and silc_client_del_client_by_id.
1559 Affected file lib/silcclient/idlist.c.
1561 * Moved the clientincludes.h from includes/ to silc/ and
1562 serverincludes.h from includes/ to silcd/.
1564 * The modes for the CMODE and CUMODE are now passed as
1565 uint32 for application with COMMAND_REPLY. The affected
1566 file is lib/silcclient/command_reply.c.
1568 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1570 * /WHOIS without arguments shows client's own information.
1571 Affected file lib/silcclient/command.c.
1573 * Changed PING to not accept any arguments. The specs
1574 says that client can ping only the connected server so
1575 requiring an argument is not needed. Affected file is
1576 lib/silcclient/command.c.
1578 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * Fixed a fatal bug in private message sending and reception
1581 encryption and decryption when using private message keys.
1582 The implementation was incorrect and did not follow the
1583 specification. It causd that some of the message were
1584 lost since it did not use the sending and receiving keys
1585 as the protocol suggests. This has been fixed and will cause
1586 incompatibilities with older clients when sending private
1587 message encrypted with private message keys. Affected files
1588 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1589 and various other in Irssi SILC Client.
1591 Added `responder' boolean argument to the functions
1592 silc_client_add_private_message_key[_ske] to indicate when
1593 the key is added as responder or initiator of the key
1596 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1598 * Removed the silc_ske_check_version function and created
1599 a SilcSKECheckVersion callback. Added also a function
1600 silc_ske_set_callbacks that is now used to set all SKE
1601 callbacks. The callback functions are not given to
1602 the SKE functions anymore, but this function is used to
1605 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1607 * Added `silc_version' argument to the silc_client_alloc
1608 to define the version of the application for the library.
1609 The library will use the version string to compare it
1610 against the remote host's (usually a server) version
1611 string. Affected file lib/silcclient/silcapi.h
1613 * Added the KE protocol context to Key Agreement context
1614 in client library so that we can abort the SKE if it
1615 is in process when we get timeout. Affected file is
1616 lib/silcclient/client_keyagr.c.
1618 * Do not resolve the client ID forever if it returns in the
1619 first time that such client does not exist. This was done
1620 for example with private message. Affected file is
1621 lib/silcclient/client_prvmsg.c.
1623 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1625 * Do not add regex.h for WIN32. The affected file
1626 includes/silcincludes.h.
1628 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1629 not work yet 100%. It generates the DLL's automatically
1630 when compiling with --with-win32 under cygwin.
1632 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1634 * lib/contrib/regex.c is not compiled on WIN32.
1636 * Added silc_net_get_socket_opt function to the
1637 lib/silcutil/silcnet.h.
1639 * Added includes/silcwin32.h for WIN32 specific includes
1642 * Do not use ptime structure or any of the posix process
1643 functions on WIN32 in lib/silccrypt/silrng.c.
1645 * Added silc_gettimeofday to provide generic function
1646 for struct timeval on all platforms. Added the function
1647 to lib/silcutil/silcutil.h.
1649 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1651 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1652 library as they clearly belong there. As a plus side we
1653 can make the actual socket connection routines platform
1656 Added also new generic function silc_socket_read and
1657 silc_socket_write (that used to be silc_packet_[read/write].
1658 The implementation of these are platform specific.
1660 * Added WIN32 specific routines of silc_socket_[read/write]
1661 to lib/silcutil/win32/silcwin32sockconn.c.
1663 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1665 * Added preliminary support for native WIN32 compilation under
1666 cygwin (using the -mno-cygwin option for GCC) to the
1667 ./configure.in.pre. The --with-win32 now prepares the
1668 compilation for native WIN32.
1670 * Rewrote the SILC Scheduler interface in the file
1671 lib/silcutil/silcschedule.h. The scheduler is now context
1672 based and does not have anymore any global static scheduler.
1673 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1674 and created lib/silcutil/win32 directory for WIN32 based
1677 * Added Unix specific network routines to the
1678 lib/silcutil/unix/silcunixnet.c and the old
1679 lib/silcutil/silcnet.c includes now only generic routines.
1681 Added WIN32 specific network routines to the
1682 lib/silcutil/win32/silcwin32net.c.
1684 * Added Unix specific utility functions from the
1685 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1687 * Added WIN32 SILC Scheduler to the file
1688 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1691 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1693 * Do not handle JOIN notify in the server if the target client
1694 is not registered (idata->registered == FALSE). The affected
1695 file is silcd/packet_receive.c.
1697 * Update the nickrec->founder in event_cumode in the Irssi SILC
1698 client. Affected file irssi/src/silc/core/silc-channels.c.
1700 * Fixed the CUMODE_CHANGE notify handling in the server when
1701 server and router are announcing their clients on channels.
1702 Now the mode changes are saved and notified correctly. The
1703 affected file is /silcd/packet_receive.c.
1705 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1706 They really did not replace the cache entry in the ID Cache.
1707 Now they do that. Affected file silcd/idlist.c.
1709 * Fixed the KICK notify handling in the Irssi SILC client to
1710 update the channel records so that the kicked client does not
1711 appear to be on the channel. The affected file is
1712 irssi/src/silc/core/silc-channels.c.
1714 * Always update the conn->current_channel when executing command
1715 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1717 * Fixed the KILL notify handling in Irssi SILC client to remove
1718 the killed client on all channels.
1720 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1722 * Fixed the silc_parse_command_line to remove extra spaces
1723 from the start and end of the arguments. Affected file is
1724 lib/silcutil/silcutil.c.
1726 * Cancel and free any active protocol in the function
1727 silc_server_close_connection. Affected file silcd/server.c.
1729 * Cancel and free any active protocol in the function
1730 silc_client_close_connction. Affected file is
1731 lib/silcclient/client.c.
1733 * Do not execute the KILL command for clients that are in
1734 history (ie. they are not in the network). Affected file is
1737 * Fixed KILL notify handling, client does not crash anymore.
1738 Affected file irssi/src/silc/core/silc-channels.c.
1740 * Reduced the default packet buffer size from 2048 to 1024 in
1741 lib/silccore/silcpacket.c.
1743 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1744 counter to the SKE context that is incresed when the SKE library
1745 performs async operation outside the library. If the outside
1746 process frees the SKE context and FREED status will be set
1747 and the library will detect after the sync operation that the
1748 libary is freed. The affected files are
1749 lib/silcske/silcske[_status].[ch].
1751 * Resolve the client entry information in the function
1752 silc_client_channel_message to assure that NULL pointer is not
1753 passed as client entry to the application. */
1755 * Fixed the task timeout calculation to assure that there is
1756 never negative timeouts. The affected file is
1757 lib/silcutil/silcschedule.c.
1759 * Fixed the channel user mode notification sending in server.
1760 It was sent point-to-point to the router (or to server by router)
1761 but it needs to be destined to a channel. The routines now
1762 supports sending the channel user mode notifys to the channels
1763 when announcing clients and channels. Affected files are
1764 silcd/server.c and silcd/packet_receive.c.
1766 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1767 It did not actually replace the old channel entry in the cache.
1768 Affected file lib/silcclient/client_notify.c.
1770 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Fixed a possible crash in silc_packet_send_prepare. It now
1773 assures always that there is enough space in the buffer and
1774 at the tail area of the buffer (for MAC).
1776 Fixed the inbound buffer reallocation in silc_packet_read.
1777 It was old code and did not handle the reallocation correctly.
1780 The affected file is lib/silccore/silcpacket.c.
1782 * Fixed buffer overflow in silc_parse_nickname in the file
1783 lib/silcutil/silcutil.c.
1785 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * make install generates new server keys only if there is not
1790 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1792 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1793 Added check that if the NOREPLY is set then we will not send
1794 the away message. This avoids infinite loop of away messages
1795 if both clients are away. The affected file is
1796 lib/silcclient/client_prvmsg.c.
1798 * Fixed client crash if /NICK was given without arguments.
1799 Affected file lib/silcclient/command.c.
1801 * Server does not send the invite list in INVITE command back
1802 to the client if the list was not altered. Added this notion
1803 to the protocol spec as well. Affected file silcd/command.c.
1805 Fixed possible crash in INVITE command by checking the
1806 value of silc_server_get_client_route command.
1808 * Fixed the INVITE notify type handling. The arguments are now
1809 taken in correct order and client does not crash. The affected
1810 file is irssi/src/silc/core/silc-channels.c.
1812 Removed the "Inviting xxx to channel" message from the
1813 client library away and let the application handle it.
1814 Affected file lib/silcclient/command.c. Added that message
1815 to Irssi SILC client's message formats.
1817 * Fixed CMODE command crash in client. It now checks the
1818 amount of arguments correctly and does not crash. The affected
1819 file is lib/silcclient/command.c.
1821 * Do not create new channel automatically in silc_channels_join
1822 but check whether the channel by that name already exists.
1823 Affected file irssi/silc/core/silc-channels.c.
1825 * Do not send the SERVER_SIGNOFF to router if the disconnected
1826 entity was the router. Affected file silcd/server.c.
1828 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1829 SILC client as it was missing from there.
1831 Added the handling of the KICK notify to the Irssi SILC client
1832 as it was missing. Added "you have been kicked" message to
1833 Irssi SILC client's message modules formats.
1835 Added the handing of the KILL notify to the Irssi SILC client
1836 as it was missing. Added the kill message module formats
1839 The affected file is irssi/src/silc/core/silc-channels.c.
1841 * The router did not save the channel mode the server announced.
1842 Affected file silcd/packet_receive.c.
1844 * Fixed a possible crash in INFO command in server. If the
1845 server did not provide the server info it crashed. Affected
1846 file silcd/command.c.
1848 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1850 * Fixed the GETKEY command in the server to check also the
1851 global list. Otherwise the GETKEY would not work correctly
1852 in normal SILC server. Affected file silcd/command.c.
1854 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Fixed GETKEY crash, it crashed if the command did not succseed.
1858 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1860 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1861 is now real and not just an macro interface to GMP.
1863 Removed the entire GMP from the source tree and imported new
1864 NSS MPI library instead. Reason for removing GMP is that it is
1865 extremely large and compiles extremely slow. The NSS MPI
1866 is only a few files and compiles in less than 10 seconds.
1867 The speed is also about the same as GMP. The MPI is imported
1868 to lib/silcmath/mpi.
1870 If the system has GMP installed we will still use the GMP.
1871 If it is not then the NSS MPI will be compiled.
1873 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1875 * Merged a long nickname (127 characters long) crash bugfix from
1876 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1878 * Merged a freed memory reference bugfix from Irssi CVS tree.
1879 Affected file irssi/src/core/commands.c.
1881 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Added the server's public key sving and verification to the
1884 server when performing the SKE. This was missing and the
1885 remote server's (or router's) public key was accepted without
1886 checking whether we have it previously or trust it at all.
1887 Affected file silcd/protocol.c.
1889 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1891 * Check in the silc_server_timeout_remote if protocol is active
1892 and make sure that the protocol's final callback is called so
1893 that all memory if freed. Affected file silcd/server.c.
1895 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1897 * silc_server_whois_send_reply crashed the server if the nickname
1898 was 127 characters long. Affected file silcd/command.c.
1900 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Added sanity check to the silc_server_new_client. If the hostname
1903 is provided inside username then check that the provided hostname
1904 really is the same as the resolved one. If the hostname was not
1905 resolved then check it from the public key. Affected file is
1906 silcd/packet_receive.c.
1908 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1909 if the server disconnected us and the connection is not valid
1910 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1912 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1913 the library to the lib/silcutil/silcutil.[ch].
1915 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1917 * Close log file after open. Affected file
1918 lib/silcutil/silclog.c.
1920 * Check whether sock == NULL in silc_client_send_packet and return
1921 if it is. Affected file lib/silcclient/silcclient.c.
1923 * Check rec->entry == NULL in the Irssi SILC Client before
1924 sending the channel message. Affecte file is
1925 irssi/src/silc/core/silc-servers.c.
1927 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Merged a splitted window bugfix from Irssi CVS tree. The
1930 affected file is irssi/src/fe-text/textbuffer-view.c.
1932 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1933 It did not print nickname.
1935 * Improved the distributions system a bit.
1937 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1940 irssi/src/fe-text/gui-window.c.
1942 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1943 to in-active server. The affected file is
1944 irssi/src/silc/core/client_ops.c.
1946 * Resolve the client in USERS command reply if the entry does
1947 not have username resolved. The affected file is
1948 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1949 command to WHOIS command to really resolve stuff. The USERS
1950 is not used any more in any critical section so WHOIS can
1951 be used even though it might be slower than IDENTIFY.
1953 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1956 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Changed the protocol API a bit more consistent in the
1959 lib/silccore/silcprotocol.[ch].
1961 * Changed the following headers to ROBODoc format:
1963 lib/silccore/silcpayload.h
1964 lib/silccore/silcprotocol.h
1965 lib/silccore/silcsockconn.h
1967 All core library headers are now formatted.
1969 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Fixed a bug in Irssi SILC client; do not show that you are
1972 server/router operator if you really are not. Affected file is
1973 irssi/src/silc/core/client_ops.c.
1975 * Renamed silc_command_free_payload to silc_command_payload_free.
1976 Affected file lib/silccore/silccommand.h
1978 * Added silcmath.h to include the prototoypes of various routines
1979 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1982 * Changed the following headers to ROBODoc format:
1984 lib/silccore/silcchannel.h
1985 lib/silccore/silccommand.h
1986 lib/silccore/silcid.h
1987 lib/silccore/silcidcache.h
1988 lib/silccore/silcmode.h
1989 lib/silccore/silcnotify.h
1990 lib/silccore/silcpacket.h
1991 lib/silcmath/silcmath.h
1993 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * Added checking to the server code not to start the server if
1996 ciphers and stuff are not configured properly. Affected files
1997 silcd/serverconfig.[h] and silcd/server.c.
1999 * Changed the layout of the header files of the public interfaces
2000 in the SILC libraries. The new layout supports ROBODoc
2001 documentation tool (and some others) so that it is easy to create
2002 a library reference manual. All the other headers and source
2003 code must still follow the CodingStyle document. Also source
2004 code must not include these ROBODoc stuffs, only the headers.
2005 Furthermore, all public interface headers must now be named
2006 by using `silc' prefix, example: silcapi.h, silccipher.h.
2007 Some files were renamed due to this. All the other headers
2008 must not be used as public interfaces. I will update the
2009 CodingStyle document later. Changed following headers, so far:
2011 lib/silcclient/silcapi.h
2012 lib/silccore/silcauth.h
2013 lib/silccore/silcprivate.h
2014 lib/silccrypt/silcdh.h
2016 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2020 * Removed silc_client_packet_send_flush from the client library
2021 as it is not needed. Affected file lib/silcclient/client.[ch].
2023 * Added printing of message of unresolved authentication method
2024 to the Irssi SILC client. Added it to the module formats.
2025 Removed the same message from the client library.
2027 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2029 * Added new distribution feature, DISTLABEL. Every distribution
2030 can define own preprocessor label that can be used in the
2031 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2032 file distributions, acconfig.h.pre and prepare.
2034 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Added Makefile.defines_int to include the actual definitions
2037 for Makefile.defines.in. Tested the new distribution system,
2038 created distributions and tested installation.
2040 * Added AWAY message printing to the Irssi SILC client. Added
2041 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2043 * Added SCONNECT command to call the SILC's CONNECT command.
2044 Cannot use CONNECT directly since Irssi uses that internally.
2045 Affected file irssi/src/silc/core/silc-servers.c.
2047 Added ACTION local command. It is same as ME command but takes
2048 the channel as mandatory argument.
2050 Rewrote some of the Irssi's help files to suite for SILC
2053 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Added Makefile.defines[.in] that should for now on be included
2056 in all Makefile.am file in the source tree. That file includes
2057 all common compilation definitions for SILC source tree.
2059 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * Minor changes to the ./prepare script to change the package
2062 name according the distribution name to the configure.in.
2064 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Created new distribution system. Added file `distributions'
2067 that defines all the distributions that can be created out of
2068 the SILC source tree. The ./prepare script now reads that
2069 file to determine how to prepare the distributions. The
2070 first argument to the ./prepare is the name of the distribution
2071 and second is the version of the distribution. If given
2072 without arguments it creates the default (toolkit) distribution
2073 with the default version (defined in ./prepare).
2075 All Makefile.am files that are subject to the distributions
2076 are now named as Makefile.am.pre. These are ./Makefile.am
2077 and lib/Makefile.am. Others may be changed later.
2079 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Added invite list, ban list, some key management and connection
2082 error message printing to module formats in the Irssi SILC client.
2084 * Added new silc_client_set_away_message to set the away message
2085 that is back to the person who sent private message. The
2086 affected file lib/silcclient/silcapi.h and the
2087 lib/silcclient/client_prvmsg.c.
2089 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Fixed the private message sending in the Irssi SILC client,
2092 added local command KEY to the Irssi SILC client.
2094 Added key management and key agreement message formats to the
2095 irssi/src/fe-common/silc/module-formats.[ch].
2097 Added USERS (alias WHO) printing, server/router operator
2098 indication and LIST command printing to the module formats.
2100 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * Fixed channel joining notify handling, cumode notify handling
2103 from Irssi SILC client.
2105 * Added SILC specific module-formats to the Irssi SILC client so
2106 that SILC specific message hilighting, colors etc is possible.
2107 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2109 Added channel mode, channel user mode, actions, notices,
2110 whois and whowas printing to the the module-formats.c.
2112 * Fixed a bug in channel deletion in the server. The channel
2113 is not left to the cache even if the channel founder auth mode
2114 is set when there are no users anymore on the channel. Affected
2115 file silcd/server.c.
2117 * The silc_net_localhost now resolves the entire hostname including
2118 the domain name. Affected file lib/silcutil/silcnet.c.
2120 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2122 * Changed the ask_passphrase client operation to be ascynchronous.
2123 It has now a completion callback and a context that the
2124 application must call after it has got the passphrase from
2125 the user. Affected files lib/silcclient/silcapi.h,
2126 lib/silcclient/protocol.c, lib/silcclient/command.c and
2129 Added SilcAskPassphrase callback that the application calls
2130 to deliver the passphrase to the library.
2132 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2133 The public key verification and especially a certificate
2134 verification is asynchronous procedure.
2136 Added new SILC_SKE_STATUS_PENDING status to indicate the
2137 request is pending and a callback will be called to finalize
2140 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2141 indicate that remote end did not send its public key (or
2142 certificate), even though we require it. Added check for this
2143 condition in the SKE. This was a security bug, now fixed.
2145 Defined new SilcSKEVerifyCbCompletion callback that is called
2146 when the verification process is completed.
2148 The affected files lib/silcske/silcske_status.h and
2149 lib/silcske/silcske.[ch].
2151 * Changed the verify_public_key client operation to be async
2152 as well. Defined SilcVerifyPublicKey callback that is used to
2153 indicate the success of the public key verification process.
2155 Changed the server and client to use the new async client
2158 * Changed the Irssi SILC client's internal scheduler to be called
2159 twice as many times as it used to be. As a result the client
2160 should be a bit faster now. Affected file is
2161 irssi/src/silc/core/silc-core.c.
2163 * Added support to Irssi SILC client of asynchronous public key
2164 verification and passphrase inquiry. Affected file is
2165 irssi/src/silc/core/silc-core.c.
2167 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Do not say "You have left channel %s" in client library.
2170 Moved it to the application. Affected files are
2171 lib/silcclient/command.c and silc/client_ops.c.
2173 * Fixed silc_client_get_clients. Command context was not
2174 duplicated and was freed memory in the callback. Affected
2175 file lib/silcclient/idlist.c.
2177 * Do not say "you are now talking..." on JOIN command in the
2178 client library. The appliation must handle it.
2180 * Do not say ".. changed topic to" in command reply in the
2181 client libary. The application must handle it.
2183 * Fixed TOPIC command sending in the client library.
2185 * Fixed a memory leak in silc_client_command_free in the file
2186 lib/silcclient/command.c.
2188 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2190 * Imported a modified version of Irssi client to the source tree.
2191 The Irssi will be used to create a new client called
2192 Irssi SILC. Imported to irssi/.
2194 Added silc_core_init_finish function to the Irssi. Affected
2195 file irssi/configure.in.
2197 A lot changes in the Makefile.ams around the irssi tree.
2199 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Do not rehash if the new size is same as the old size of the
2202 hash table, in the silc_hash_table_rehash*. The affected file
2203 lib/silcutil/silchashtable.c.
2205 * Replaced hash_table_del_by_context calls from the server
2206 (when channel->user_list and client->channels) to the
2207 hash_table_del as it is sufficient and faster.
2209 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Added silc_hash_table_list, silc_hash_table_get and the
2212 SilcHashTableList structure to provide an alternative way to
2213 traverse the hash table. The affected files are
2214 lib/silcutil/silchashtable.[ch].
2216 * Changed the server's idlist routines to use the hash table
2217 routines to optimize the code.
2219 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2221 * Replaced the client entry's `channel' list and channel entry's
2222 `user_list' list to hash tables for optimized lookup. Changed
2223 the code to use the hash table interface around the code.
2224 Affected file lib/silcd/idlist.[ch].
2226 * Added `auto_rehash' boolean argument to the function
2227 silc_hash_table_alloc to indicate whether the hash table should
2228 auto-rehash when it thinks is appropriate time. It will
2229 increase the hash table size if the there is twice as much
2230 entries in the table than the size of the table, and will
2231 decrease the size if there are twice as less entries than
2232 the size of the table.
2234 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2238 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * silc_idcache_purge_by_context deletes the entry now by context
2241 as it is supposed to do. Affected file lib/silccore/idcache.c.
2243 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2244 client is not anymore valid (WHOWAS givens the info) and not
2245 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2247 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2249 * Removed the `data' and `data_len' arguments from the ID Cache
2250 interfaces and added `name' argument. ID Cache does not handle
2251 anymore the binary data only a names associated with given ID.
2253 * When hashing a Client ID with silc_hash_id the entire ID is
2254 not hashed anymore, instead only the hash of the Client ID is
2255 hashed. This way we can access the Client ID from the cache
2256 with Client ID but with the hash of the ID (which is a hash of
2257 the nickname) as well without any difference in performance.
2259 Added also silc_idcache_find_by_id_one_ext to do one on one
2260 searching when we have the actual ID. Added also function
2261 silc_hash_client_id_compare. The affected files are
2262 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2264 * When hashing the name associated with a ID it is always done
2265 in lowercase. This way we can access the cache without worrying
2266 about case-sensitivity, even though, for example nicknames are
2269 * Fixed a bug in server with channel message sending. It put
2270 wrong ID type as destination ID. The affected file
2271 silcd/packet_send.c.
2273 * silc_idcache_del_by_context now deletes from all hash tables
2274 by context. Affected file lib/silccore/idcache.c.
2276 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Changed the client library to use the new ID Cache interface.
2279 Changes around the source tree.
2281 * Added silc_hash_table_rehash_ext to rehash with specific
2282 hash function. Affected file lib/silcutil/silchashtable.[ch].
2284 * Added silc_hash_string_compare to compare two strings in the
2285 hash table. Affected file lib/silcutil/silcutil.[ch].
2287 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2289 * Added new function silc_idcache_del_by_context into the
2290 lib/silccore/idcache.[ch].
2292 * Changed the server's ID list routines to use the new ID Cache
2293 interface. Changes around the source tree.
2295 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2297 * Added silc_hash_table_del[_by_context]_ext functions in to the
2298 lib/silcutil/silchashtable.[ch].
2300 Removed silc_hash_table_find_all* routines and added new
2301 silc_hash_table_find_foreach to replace them.
2303 Added silc_hash_table_replace_ext function as extended
2304 replacing function. Separated the simple hash table interface
2305 from the extended hash table interface in the file
2306 lib/silcutil/silchashtable.h.
2308 * Fixed minor bugs and changed it to use some of the new
2309 hash table functions in lib/silccore/idcache.c
2311 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2313 * Added new function silc_hash_table_find_all to return all keys
2314 in the hash table by the specified key. As the hash table is
2315 collision resistant it also makes it possible to have several
2316 duplicate keys in the hash table. This function may be used to
2317 find all of the keys from the hash.
2319 Added user_context arguments to the SilcHashFunction,
2320 SilcHashCompare and SilcHashDestructor to deliver user specified
2323 Added new fuctions silc_hash_table_find[_all]_ext to do
2324 extended lookup with specified hash and compare functions and
2325 specified user contexts.
2327 Added new function silc_hash_table_add_ext to add the key
2328 with specified hash function and user context.
2330 Added new function silc_hash_table_foreach to traverse all
2331 entrys in the hash table. Added SilcHashForeach callback
2334 Added new function silc_hash_table_del_by_context to delete
2335 the entry only if the context associated with the key matches.
2337 Affected files are lib/silcutil/silchashtable.[ch].
2339 * Removed silc_hash_[server/client/channel]_id and added just
2340 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2341 silc_hash_id_compare to compare two ID's using as the hash table
2342 comparison function. Added also silc_hash_data to hash
2343 binary data and silc_hash_data_compare to compare it.
2345 * Removed silc_idlist_find_client_by_hash as it is not needed
2346 anymore. Affected file silcd/idlist.[ch].
2348 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2349 to use internally the SilcHashTable. The new ID Cache is a lot
2350 faster than the old one. Some of the ID Cache interface was also
2351 rewritten and obsolete and stupid functions were removed.
2353 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2355 * Added entry_count field to the SilcHashTable to keep the number
2356 of the entries in the table. Implemented the function
2357 silc_hash_table_rehash. Added new function
2358 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2360 Fixed a minor bug in silc_hash_table_free.
2362 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2363 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2364 into the lib/silcutil/silcutil.[ch].
2366 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2368 * Implemented a collision resistant hash table into the
2369 lib/silcutil/silchashtable[ch]. See the header and the source
2370 for the SilcHashTable API.
2372 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Merged dotconf version 1.0.2 into lib/dotconf.
2376 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Do not compile anything in lib/silcsim/* if the SIM support
2379 is not enabled. The tree should now compile without problems
2382 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Compiled the SILC under cygwin. Compiled and tested briefly
2385 without problems. More tests needed. The SIMs didn't compile
2388 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2390 * Fixed possible crash in silc_get_username in the
2391 lib/silcutil/silcutil.c.
2393 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2395 * Fixed a va_arg in silc/client_ops.c.
2397 * Oops, RC5 routines were named AES and caused some problems
2398 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2400 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2402 * Added new SilcIDIP structure into the lib/silccore/id.h and
2403 replaced the old `ip' fields from all SILC ID's to that type.
2404 This is a step towards IPv6 support.
2406 The silc_id_get_len takes now the ID as an extra argument.
2407 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2408 both IPv4 and IPv6 based ID's.
2410 The affected files are lib/silccore/id.[ch] and other files
2411 around the tree using these routines.
2413 * Removed the ID length arguments in server from various
2414 silc_server_send_notify_* routines -> they are not needed
2417 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Fixed memory leak in silc_encode_pem_file in the file
2420 lib/silcutil/silcutil.c.
2422 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Check minor version as well in the SKE. Affected files are
2425 silcd/protocol.c and lib/silcclient/protocol.c.
2427 * Added --identifier option to the server so that an identifier
2428 can be when creating the public key for the server. Affected
2429 file is silcd/silcd.c.
2431 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2432 lib/silccrypt/silcpkcs.c.
2434 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Register default ciphers and stuff when using -C option with
2437 the server. Affected file sildc/silcd.c.
2439 * Put back the servers public key filename format, it is better
2440 than the new one. For now, the client keys are saved with the
2441 new filename format. The affected file silc/client_ops.c.
2443 * Implemented the Cipher API for the rest of the ciphers that
2444 did not implement it or implemented it the wrong way.
2446 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Register default ciphers and stuff when using the -S option
2449 in the client. Affected file silc/silc.c. Same also when
2450 creating new key pair with -C option.
2452 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Fixed the silc_verify_public_key client operation function to
2455 save the public keys differently. The fingerprint is now
2456 used as filename and not the hostname. This way also the
2457 client keys are saved uniquely and not with hostnames. The
2458 affected file is silc/client_ops.c.
2460 * Trimmed the silc_hash_fingerprint function to remove extra
2461 whitespaces from the end of the fingerprint. The affected
2462 file is lib/silccrypt/silchash.c.
2466 * Added silc_cipher_register_default function to register all
2467 default ciphers. It can be used when configuration files
2468 does not exist and the application does not want any specific
2469 ciphers in any specific order.
2471 The SilcDList is now used as silc_cipher_list dynamically
2472 allocated cipher list. Removed the static list all together
2473 and now all ciphers must be allocated to the dynamic list.
2474 The silc_cipher_alloc routine was changed to check only the
2477 All silc_cipher_* routines that used to return int returns
2480 The affected files lib/silccrypt/silccrypt.[ch].
2482 * The same thing was done to silc_hash_* as for silc_cipher_*
2483 routines. Affected files lib/silccrypt/silchash.[ch].
2485 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2486 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2487 Added also silc_pkcs_[un]register[_default] functions.
2488 Removed the data_context from the PKCS API.
2490 * Added silc_hmac_register_default function to register default
2491 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2492 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2493 to unregister all hmacs at once.
2495 * Register the default ciphers, hash functions, PKCSs and HMACs
2496 if client's configuration file does not exist. The affected
2499 * The client did not load the hash functions from the SIM
2500 modules at all. Added support for this. Affected file is
2501 silc/clientconfig.c.
2503 * When decoding public key with silc_pkcs_public_key_decode, check
2504 the supported algorithm only if PKCS are registered. Affected
2505 file lib/silccrypt/silcpkcs.c. The same was done with the
2506 silc_pkcs_private_key_decode.
2508 * Fixed the SILC List routines to keep the list always in order.
2509 It used to change the list's order when traversing the list but
2510 not it preserves the order. Affected file lib/trq/silclist.h.
2512 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added the client library to use the SilcSocketConnection's
2515 reference counter (by silc_socket_dup) to prevent the bug that
2516 the socket object may be freed underneath async operation.
2518 * The name resolv library checking fixes in the configure.in.pre.
2521 * Created new version of the protocol drafts for future
2522 development. The -03 drafts are the ones that will be changed
2523 in the trunk now and the -02 will remain as they are.
2525 * Send list of CUMODE notifys to the router when announcing
2526 the channel users to the router. Affected file silcd/server.c.
2527 If the router receiving channel founder CUMODE for a channel
2528 that already has channel founder it will send CUMODE notify
2529 to the sender to remove the channel founder rights from the
2530 announced client. Affected file silcd/packet_receive.c.
2532 * The CUMODE notify may now use Server ID as well as the entity
2533 who changes the mode. Updated protocool specs.
2535 * Updated INSTALL and README files.
2537 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * New web pages in the http://silc.pspt.fi. The pages was
2544 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2546 * Implemented the [DenyConnectin] config section in the server.
2547 Added silc_server_config_denied_conn to check whether incoming
2548 connection is denied. Affected file silcd/serverconfig.[ch].
2550 * Do not check the ports when checking the incoming configuration
2551 data if the port is 0, meaning any. Affected file is
2552 silcd/serverconfig.c.
2554 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2556 * Fixed buffer overflow in silc_string_compare in the file
2557 lib/silcutil/silcutil.c.
2559 * Fixed double free in silc_server_command_leave in the file
2562 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2564 * Fixed the version checking in the server. Affected file is
2567 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2569 * Fixed the configuration data fetching when accepting new
2570 connections in the server. Affected file silcd/server.c.
2572 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Added `sender_entry' argument to the function
2575 silc_server_packet_relay_to_channel so that we can check
2576 whether some destination actually belongs to the same route
2577 the sender belongs (ie, we must not resend the packet to the
2578 sender). Affected file silcd/packet_send.[ch].
2580 * Added `servername' field to the SilcClientEntry in the server
2581 to hold the name of the server where client is from. Affected
2582 file is silcd/idlist.h.
2584 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Moved the channel message encrypting in the router betwen
2587 router connections from silc_server_channel_message to the
2588 silc_server_packet_relay_to_channel since we want to check
2589 whether we have anybody channel before encrypting anything.
2590 Affected files silcd/packet_[receive/send].c.
2592 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Fixed the [AdminConnection] server config section to support
2595 multiple entries. Affected file silcd/serverconfig.c.
2597 * Added support into the server to check the validity of the
2598 incoming connection before executing any KE or authentication
2601 * The connection configuration is now saved to the KE and
2602 connection auth protocol contexts and not fetched anymore in
2603 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2605 * The local hosts listenning address and port is also resolved
2606 now when starting the server. We want to have the socket object
2607 to include the real address and port for the listener. Added
2608 new function silc_net_check_local_by_sock into the files
2609 lib/silcutil/silcnet.[ch].
2611 * Fixed a broadcast bug in server -> do not broadcast if we
2614 * Fixed a routing bug. Do not route broadcast packets ever.
2615 Broadcast packets must be processed always and not routed since
2616 they may be destined to some other host than yourself and thus
2617 would get routed without no good reason. Affected file is
2620 * Added function silc_server_config_is_primary_route to check
2621 whether primary router connection has been configured (a router
2622 configuration that we are initiating). If there is not, we
2623 will assume that there is only two routers in the SILC network
2624 and we will use the incoming router connection as our primary
2625 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2627 * Changed the order of the broadcasting. Broadcast _after_ the
2628 packet has been processed not before. Affected file is
2631 * Fixed a [ClientConnection] parsing bug. The port was never
2632 parsed correctly thus resulting to port 0. Affected file
2633 silcd/serverconfig.c.
2635 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2636 argument and did not set the broadcast packet flag. Affected
2637 file silcd/packet_send.c. Fixed same bug in the function
2638 silc_server_send_notify as well.
2640 * If we receive NEW_ID packet for our own ID in the server, ignore
2643 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Removed the nickname from the Private Message Payload.
2648 Updated the code and the protocol specs.
2650 * Updated protocol specs for submitting to the IETF.
2652 * Tweaked the Random Number Generator a bit. Affected file
2653 lib/silccrypt/silcrng.c. Exported a new function
2654 silc_rng_[global]_add_noise which can be used to add more
2657 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2659 * Do not parse packets with different timeout when protocol
2660 is active -> may cause problem with rekey. Affected file
2663 * When server receives signoff notify it must not create
2664 new channel key if the client is on any channels since the
2665 sender of the signoff notify will create it.
2667 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Added printing of error messages during SKE protocol from the
2670 failure packet sent by server during SKE. Affected file
2673 * Removed the client's failure_callback handling with timeout
2674 and handle it immediately when received.
2676 * The SKE library returned wrong type in SUCCESS and FAILURE
2677 packets. They must be 32 bit MSB not 16 bit MSB.
2679 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Ok, rewrote the logic of the re-key and now it seems to work.
2682 I tested it on high traffic with frequent re-keys without
2683 problems. Added hmac_receive (and renamed hmac to hmac_send)
2684 in SilcClientConnection in lib/silcclient/client.h and
2685 in SilcIDListData in silcd/idlist.h. Also, removed the
2686 SilcPacketParserContext's cipher and hmac fields as they are
2687 not needed anymore and actually caused some problems when
2688 the ciphers and hmac's changed underneath the packet parser.
2690 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * If re-key protocol is active then process the incoming packets
2693 synchronously since we must assure that icoming packets encrypted
2694 with the old key is processed before the new keys is set to
2695 use. This is true other packets than for REKEY packets.
2696 Affected file silcd/server.c. The same was done to client library
2697 as well, affected file lib/silcclient/client.c.
2699 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Fixed bug in client and server to accept the force send if
2702 the packet is send from silc_[server/client]_packet_process
2703 function. Otherwise the packets are never delivered, oops.
2705 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Disable force sending of packets when REKEY protocol is active.
2708 We must assure that no packet is sent directly when rekey is
2709 performed. All packets must be sent through packet queue.
2710 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2711 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2712 function is silc_[server/client]_packet_send_real to check
2715 * Replaced the SIM paths from example config files to
2716 /usr/local/modules. Also, make install creates now
2717 /usr/local/silc/logs directory to hold all the SILC server
2720 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2722 * Made the configure.in.pre work on Solaris. Patch by salo.
2724 * Made all ciphers compatible with non-x86 machines. Defined
2725 CBC mode macros into lib/silccrypt/ciphers_def.h.
2727 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Fixed the make install.
2731 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * When MAC computation fails the silc_packet_decrypt returned 0
2734 even though it was supposed to return -1. Fixed this. The
2735 affected file is lib/silccore/silcpacket.c.
2737 * Do not replace the config files in /etc/silc (in make install)
2738 if they already exist. Affected file ./Makefile.am.
2740 * Do not send re-key packets immediately but through packet queue.
2741 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2743 * Changed silc_net_check_host_by_sock to return FALSE if the
2744 IP/DNS could not be resolved. Though, it returns the IP address
2745 now even if it could not resolve it (but returns also FALSE).
2746 Affected file lib/silcutil/silcnet.[ch].
2748 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Added silc_pkcs_decode_identifier to decode the public key's
2751 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2752 Added also silc_pkcs_free_identifier. Added also new context
2753 SilcPublicKeyIdentifier.
2755 * Added -S option to the silc client. It is used to dump the
2756 contents of the specified public key file.
2758 * Changed the PKCS api to return the public key length when
2759 setting the public key.
2761 * Fixed a fatal bug in the public and private key file loading.
2762 Affected file lib/silccrypt/silcpkcs.c.
2764 * Execute the packet parsing for client with zero (0) timeout
2765 if the protocol is active. Affected file silcd/server.c.
2767 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Made the key generation options to the silcd program. Added
2770 -C option, equivalent to client's option.
2772 * Added new [ServerKeys] config section to the server. It
2773 configures the server's public and private key.
2775 * Defined generic Public Key Payload into the protocol
2776 specification to send specific type of public keys and
2779 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2780 public key or certificate.
2782 * Implemented the GETKEY command to the server and to the
2783 client library and on user interface.
2785 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2787 * Made preliminary `make install' work.
2789 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2791 * Added SilcServerRekey context into silcd/idlist.h.
2793 * Added the PFS support as defined in the specification to the
2794 SKE protocol. Affected files lib/silcske/*.c.
2796 * Added `ske_group' field to the SilcServerRekey context to hold
2797 the number of the SKE group that is used with PFS in re-key.
2798 Affected file silcd/idlist.h.
2800 * Added PFS re-key support to the server. Affected file is
2803 * Added silc_protocol_cancel to cancel execution of the next
2804 state of the protocol. Affected file is
2805 lib/silccore/silcprotocol.[ch].
2807 * Added the re-key support with and without PFS to the client
2808 library. Re-key is performed once in an hour, by default.
2810 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2811 Added silc_client_rekey_callback and silc_client_rekey_final.
2812 Affected files are lib/silcclient/protocol.[ch] and
2813 lib/silcclient/client.[ch].
2815 * Removed the `hmac_key' and `hmac_key_len' fields from the
2816 SilcClientConnection structure; not needed. Affected file is
2817 lib/silcclient/client.h.
2821 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2823 * Do not ask whether user wants to use the negotiated private key
2824 for private messages, just use it. Affected file is
2825 silc/local_command.c.
2827 * Added `send_enc_key' and `enc_key_len' fields to the
2828 SilcIDListData structure since they are needed in the re-key
2829 phase. Affected file is silcd/idlist.[ch].
2831 * Implemented the simple re-key protocol into the server.
2832 Affected files silcd/server.c and silcd/protocol.[ch]. The
2833 re-key will be performed once in an hour, by default.
2835 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2836 Added silc_server_rekey, silc_server_rekey_callback and
2837 silc_server_rekey_final.
2839 * Removed Tunneled flag from the protocol. Updated the code
2840 and the specifications.
2842 * Adde `pfs' field to the SilcIDListData to indicate whether
2843 the PFS is to be performed in the re-key. Affected file is
2846 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2849 int64 of at least the xintXX size. If void * is less that 4
2850 bytes uint32 * will be used. Defined bool as boolean.
2852 * Changed _ALL_ unsigned long and unsigned int to uint32,
2853 unsgined short to uint16 in the source tree.
2855 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2856 not handle clients that has entry->data.registered == FALSE.
2857 They are not in the network anymore. Affected file is
2860 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2862 * Implemented the sending of the SERVER_SIGNOFF notify in the
2863 server. Affected file is silcd/server.c.
2865 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2866 Added also silc_notify_payload_encode_args into the
2867 lib/silccore/silcnotify.[ch].
2869 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2870 Affected file silcd/packet_receive.c.
2872 * Implemented the SERVER_SIGNOFF notify handling in the client
2873 library. Affected file lib/silcclient/client_notify.c. Also,
2874 implemnted the printing of the SERVER_SIGNOFF info to the
2875 application. Affected file silc/client_ops.c.
2877 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2878 if the deleting was successful. Affected file silcd/idlist.[ch].
2880 * Added support for public key authentication in the connection
2881 authentication protocol in the client library. Affected file
2882 lib/silcclient/protocol.c.
2884 * Changed the server's silc_idlist_get_clients_by_* interface
2885 to support already allocated array so that new entries may be
2886 added to pre-allocated array. Affected file silcd/idlist.[ch].
2887 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2888 and command replies.
2890 * All command reply functions in the server now calls the
2891 pending command callback even if error occured. This way the
2892 error will be delivered to the client as well. Affected files
2893 silcd/command.c and silcd/command_reply.c.
2895 * Fixed INFO command to return local server's info if no server
2896 was provided. Affected file lib/silcclient/command.c.
2898 * Removed RESTART command for good. Updated the code and the
2901 * Rewrote parts of the task system. It is a bit simpler now.
2902 Removed unsued task priorities. The affected files are
2903 lib/silcutil/silctask.[ch].
2905 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2907 * Moved the USERS printing from the library to the application.
2908 Affected files lib/silcclient/command.c and silc/client_ops.c.
2910 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2914 * Added channel key re-key support. The re-key is perfomed
2915 only by the router and is done once in an hour. Added `rekey'
2916 field to the SilcChannelEntry in the server. Affected files
2917 silcd/server.c and silcd/idlist.h.
2919 * Added silc_task_unregister_by_context into the file
2920 lib/silcutil/silctask.[ch].
2922 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2924 * Added SILC_UMODE_GONE mode to indicate when the client is not
2925 present in the SILC network. Added also support to the local
2926 command AWAY that will set this mode. Added support of showing
2927 "xxx is gone" in WHOIS command. The USERS command shows the
2928 gone status as well.
2930 * Fixed setting server and router operator privileges in the
2931 server's UMODE command. Affected file silcd/command.c.
2933 * Merged the SKE KE1 and KE2 payloads into one payload. The
2934 new KE payload is equivalent to the old KE2 payload.
2936 Cleaned up the SKE Start Payload parsing. It now uses the
2937 simple buffer unformatting to do the parsing. A lot faster
2940 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2941 to the SKE that is used to indicate whether both of the SKE
2942 parties should perform authentication. By default only the
2943 responder performs authentication. By setting this flag also
2944 the initiator must do authentication. By default it is unset
2945 since in normal SKE case, client to server connection, only
2946 the responder should do authentication. When doing SKE between
2947 two clients both should perform authentication. Updated the
2948 code and the protocol specs.
2950 * A little fix to IDENTIFY command in the server. Search the
2951 client first by hash not nickname. Affected file is
2954 * Fixed the silc_client_close_connection to support closing
2955 the client to client connections wihtout deleting too much
2956 data. Affected file lib/silcclient/client.c.
2958 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2959 are received if protocol used to be active but is not anymore
2960 the application would crash due to NULL pointer dereference.
2961 Affected files silcd/server.c and lib/silcclient/client.c.
2963 * Added `hash' field to the SilcClientConnection to include
2964 the hash function negotiated in the SKE protocol.
2966 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2967 to set the channel founder authentication data. A client can
2968 claim the founder rights later by providing the authentication
2969 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2970 This way the channel founder can regain the channel founder
2971 privileges even it is left the channel. This works only on
2972 local server and the client must be connected to the same
2973 server to be able to regain the founder rights. Updated the
2974 protocol specs accordingly.
2976 Added support to the CMODE command in the client to set the
2977 founder auth data. Read the README to see how to set it.
2979 Added support to the CUMODE command to claim the founder
2980 rights. Read the README to see how to do it.
2982 Added support for the founder authentication to the Channel
2983 Entry in the server. Affected file silcd/idlist.h.
2985 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2986 server's CMODE command. Affected file silcd/command.c.
2988 * Added the following new functions into lib/silccore/silcauth.[ch]:
2989 silc_auth_get_method and silc_auth_get_data.
2991 * The server now saves the remote hosts public key to the
2992 SilcIDListData pointer. Affected file silcd/protocol.c.
2994 * The normal server now does not remove the channel entry from
2995 the cache if the founder authentication data is set. It used
2996 to remove it if the founder was the last one on the channel on
2997 the server and left the channel. The auth data is saved and
2998 if the channel is re-joined later the old entry is used with
2999 the old auth data. Affected files silcd/command_reply.c and
3002 * Removed the `pkcs' field from the SilcIDListData structure
3003 in the server; it is not used. Affected file silcd/idlist.h.
3005 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3007 * Fixed packet processing on slow links. Partial packets were
3008 never re-processed because the incoming data buffer was cleared
3009 by the application. Application must not directly clear the
3010 sock->inbuf, the packet processing routines handle it. Fixed
3011 this in client library and in server.
3013 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3015 * Fixed the WHOIS and IDENTIFY send reply function to really
3016 check whether to send list or just one entry. Affected file
3019 * Cleaned up the LEAVE command's channel key distribution. The
3020 affected file silcd/command.c.
3022 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3023 can enforce the channel mode as well. In that case the ID
3024 includes the ID of the server. The code now enforces the
3025 mode change if the router have different mode than the server.
3027 * The notify client operation with CMODE_CHANGE notify can now
3028 return NULL client_entry pointer if the CMODE was not changed
3029 by client. Application must check for this.
3031 * Added <Server ID> argument to INFO command to support server
3032 info fetching by Server ID.
3034 * Added silc_server_announce_get_channel_users to get assembled
3035 packets of channel users of the specified channel. Affected
3036 file silcd/server.[ch].
3038 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3039 was freed underneath the ID Cache.
3041 * Re-announce clients when the server received CHANNEL_CHANGE
3042 notify from the router. Affected file silcd/packet_send.c.
3044 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3047 crashed since it did not handle the fact that there is no cipher
3048 called "3" and didn't check the error condition. Now fixed.
3050 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3051 flag. It can be used to send message requests.
3053 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3055 * Implemented the RESTART command in the client.
3057 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3058 notice type messages. Added notice printing to the user
3061 * The channel keys are not re-generated if the channel's mode
3062 is PRIVKEY, ie private key on the channel exists. Affected
3063 files silcd/server.c and silcd/command.c.
3065 * Fixed a little bug in channel message delivery when channel
3066 private keys are set in the server. Affected file is
3067 silcd/packet_send.c.
3069 * Changed the setting on channel->on_channel = TRUE from the
3070 silc_client_save_channel_key to the JOIN command reply. The
3071 key payload is not received if the private channel key is set.
3072 Affected file lib/silcclient/command_reply.c and the
3073 lib/silcclient/client_channel.c.
3075 * When the CMODE_CHANGE notify is sent and the channel private
3076 key mode is removed the channel key must be re-generated in
3077 other cells as well. Added this support for the router in the
3078 silcd/packet_receive.c.
3080 * Added new local command NOTICE to send notice message on
3081 channel. Affected file silc/local_command.[ch].
3083 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Added new local command ME to the client. It is used to send
3086 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3087 some action. Affected file silc/local_command.[ch].
3089 * Changed channel_message and private_message client operations
3090 to deliver the message flags to the application. Added also
3091 the `flags' arguments to the silc_client_send_channel_message
3092 and silc_client_send_private_message functions. Affected file
3095 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Redefined the Private Message Payload to support private message
3098 keys and to support the new private message flags. Updated
3099 the protocol specs. Flags makes it possible to have for example
3100 CTCP style messages.
3102 * Added new type SilcPrivateMessagePayload and defined an API
3103 for it in the lib/silcclient/silcprivate.[ch].
3105 * Tested private message private keys successfully. Tested the
3106 private message key set, unset and list commands with the new
3109 * Redefined the Channel Message Payload to include the channel
3110 message flags (equal with private message flags) to support
3111 for example CTCP style messages.
3113 * Defined some of the message (for channel and private message)
3114 flags. Updated the protocol specs and added the flags to the
3115 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3117 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added SilcKeyAgreementStatus type to the key agreement routines
3120 to indicate the current status and error if one occured.
3121 The status types are defined in the lib/silcclient/silcapi.h.
3123 * Added new local command KEY that is used to set and unset private
3124 keys for channels, set and unset private keys for private messages
3125 with remote clients and to send key agreement requests and
3126 negotiate the key agreement protocol with remote client. The
3127 key agreement is supported only to negotiate private message keys,
3128 it currently cannot be used to negotiate private keys for channels,
3129 as it is not convenient for that purpose.
3131 * Fixed a minor pending callback setting bug in the function
3132 silc_client_get_client_by_id_resolve, now the function works.
3133 Affected file lib/silcclient/idlist.c.
3135 * Added function silc_net_get_local_port to get local bound
3136 port by socket. Added to lib/silcutil/silcnet.[ch].
3138 * Added `sockets' and `sockets_count' fields to the SilcClient
3139 object. They hold the sockets of the listenning sockets in
3140 the client. Listenning sockets may be for example the key
3141 agreement server. Affected file lib/silcclient/client.[ch].
3142 Added functions the silc_client_add_socket and the
3143 silc_client_del_socket. They are exported to the application
3146 * Added ~./silc/clientkeys to support other client's public keys.
3148 * Renamed verify_server_key client operation to verify_public_key
3149 and added one argument to indicate the type of the connection
3150 (server, client etc.).
3152 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3154 * Added silc_server_connection_auth_request to handle the
3155 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3156 silcd/packet_receive.[ch].
3158 * Added silc_server_send_connection_auth_request into the
3159 silcd/packet_send.c to send the connection auth request packet.
3161 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3164 * Fixed the public key authentication in responder side in the
3165 server. The `auth_data' pointer includes the SilcPublicKey
3166 not the path to the public key. Affected file silcd/protocol.c.
3168 * Implemented the public key authentication in the initiator side
3169 in the server. Affected file silcd/protocol.c.
3171 * Removed the [RedirectClient] config section from the server
3172 configuration. Is not needed and I don't want to implement it.
3174 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3176 * Cleaned up the CMODE command in the server. It now works
3177 correctly and supports all the modes defined in the protocol.
3178 Affected file is silcd/command.c.
3180 * Added `hmac_name' field to the SilcChannelEntry in the server
3181 to hold the default HMAC of the channel. It can be set when
3182 creating the channel (with JOIN command). Affected files
3185 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3186 type to indicate the change of the current cipher and hmac
3187 on the channel. Client can safely ignore the <cipher> argument
3188 (if it chooses to do so) since the CHANNEL_KEY packet will
3189 force the channel key change anyway. The <hmac> argument is
3190 important since the client is responsible of setting the new
3191 HMAC and the hmac key into use.
3193 * Fixed the CMODE command in the client library as well.
3195 * Tested CMODE command in router environment successfully.
3197 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Show the version of the remote client (or server) when connecting
3200 to the server. It is logged to the log file. Affected file
3201 is silcd/protocol.c.
3203 * Fixed the KILLED notify handling in the client library. The
3204 client must be removed from all channels when receiving the
3207 Also, do not remove the client entry when giving the KILL
3208 command but when the KILLED notify is received.
3210 * Removed silc_idlist_find_client_by_nickname from the server.
3211 Not needed anymore. Affected files silcd/idlist.[ch].
3213 * Implemented the CHANNEL_CHANGE notify type handling to the
3214 server. Affected file silcd/server.c.
3218 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

3221 notify between routers.
3223 * Implemented the INVITE command correctly to the server.
3225 * Implemented the INVITE notify type handling in the server.
3227 * Implemented the INVITE command to the client library and on the
3230 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3232 * Added function silc_server_get_client_resolve to find the
3233 client entry by ID from all ID lists and then resolve it
3234 (using WHOIS) if it cannot be found. Affected file is
3237 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Implemented the BAN command to the client library.
3241 * The JOIN command in the server now checks the invite list
3244 * Changed the silc_command_reply_payload_encode_va and the
3245 silc_command_payload_encode_va to support that if argument is
3246 NULL it ignores and checks the next argument. Affected file
3247 lib/silccore/silccommand.c.
3249 * Added silc_server_send_notify_ban to send the BAN notify
3250 type between routers.
3252 * Chaned the silc_notify_payload_encode to support that if
3253 argument is NULL it ignores and checks the next argument.
3254 Affected file lib/silccore/silcnotify.c.
3256 * Tested ban lists in router environment successfully.
3258 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Implemented BAN command to the server, in silcd/command.[ch].
3262 * Removed the BAN and INVITE_LIST modes from the CMODE command
3265 * Added function silc_string_match to regex match two strings.
3266 Affected files lib/silcutil/silcutil.[ch].
3268 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3270 * Redefined parts of the SilcChannelEntry in the server to support
3271 the new ban and invite lists.
3273 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Redefined the INVITE command. The same command can be used to
3276 invite individuals to the channel but also to manage the invite
3277 list of the channel (to add to and remove from the invite list).
3278 Updated the protocol specs.
3280 * Added new command SILC_COMMAND_BAN that can be used to manage
3281 the ban list of the channel. Updated the protocol specs.
3283 * Removed the channel modes: the SILC_CMODE_BAN and the
3284 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3285 in the CMODE command. The equivalent features are now available
3286 using INVITE and BAN commands. Updated the protocol specs.
3288 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3289 in the network about change in the current ban list. The notify
3290 type is not used by the client.
3292 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3293 support the invite lists.
3295 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Added new function silc_string_regexify that converts string
3298 including wildcard characters into regex string that can
3299 be used by the GNU regex library. Added into the file
3300 lib/silcutil/silcutil.[ch].
3302 Added silc_string_regex_combine to combine to regex strings
3303 into one so that they can be used as one regex string by
3304 the GNU regex library. Added into the file
3305 lib/silcutil/silcutil.[ch].
3307 Added silc_string_regex_match to match two strings. It returns
3308 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3310 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Imported GNU regex to the soruce tree into lib/contrib.
3313 Fixed some compiler warning from the regex.c.
3315 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3317 * Fixed MOTD command in the server to work in router environment.
3319 * Fixed the MOTD command in the client library to support
3320 the server argument in the command.
3322 * Added `nickname_len' argument to the silc_idlist_add_client
3323 in the server, as the `nickname' argument may be binary data
3326 * Added silc_idlist_get_channels to return all channels from
3329 * Implemented LIST command to the server. Affected file is
3332 * Implemented the LIST command to the client library and on the
3335 * Added [<user count>] argument to the LIST command reply.
3336 With private channels the user count is not shown.
3338 * Updated TODO and README.
3340 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * The client entry's data.registered must be TRUE even with
3343 global client entry on global client list. The data.registered
3344 is used to check whether the client is anymore in the network,
3345 for example with WHOWAS command so it must be valid.
3347 * Fixed the WHOWAS command in the server. It now actually works
3348 in router environment. Added function into silcd/command_reply.c
3349 silc_server_command_reply_whowas_save.
3351 * Added silc_idlist_purge function to the silcd/idlist.c
3352 to periodically purge the ID Cache.
3354 * Fixed INFO command in the server. It works now in router
3355 environment. Added <server name> argument to the INFO command
3356 reply. Updated the protocol specs.
3358 * Fixed minor bug in silc_idcache_purge to not purge if the
3359 expire value is zero.
3361 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3362 they were buggy because of the WHOWAS information.
3364 * Fixed local command MSG to handle the async resolving of
3365 the remote client properly. It used to fail the first MSG.
3366 Affected file silc/local_command.c.
3368 * Added `data_len' field to SilcIDCache context.
3370 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Update TODO. Todo in commands in the server.
3374 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3376 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3377 used by routers as broadcast packet to inform other routers
3378 about the changed user mode.
3380 Implemented the notify handling in the server. Affected file is
3381 silcd/packet_receive.c. Added the function
3382 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3384 * Added new generic Channel Payload and deprecated the New Channel
3385 Payload. The New Channel Payload is now the generic Channel
3388 * Added new argument `mode' to the silc_server_send_new_channel
3389 as it is required in the Channel Payload now.
3391 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3392 and created a new and real SilChannelPayload to represent the
3393 new generic Channel Payload. Implemented the encode/decode
3394 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3396 * Added silc_server_get_client_channel_list to return the list
3397 of channels the client has joined for WHOIS command reply.
3398 Affected file silcd/server.[ch].
3400 * Implemented the channel list sending in the WHOIS command reply
3401 in server and in the client.
3403 Implemented the channel list displaying on the user interface
3404 as well. Affected file silc/client_ops.c.
3406 * Added silc_channel_payload_parse_list to parse list of Channel
3407 Payloads. It returns SilcDList list of SilcChannelPayloads.
3408 Client for example can use this function to parse the list of
3409 channels it receives in the WHOIS command reply. The caller
3410 must free the list by calling silc_channel_payload_list_free.
3411 Affected files lib/silccore/silcchannel.[ch].
3413 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Added one new argument <user mode> to the WHOIS command reply
3416 to return the mode of the user in SILC. Updated the protocol
3419 Implemented it to the server and client.
3421 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3423 * Fixed the mode printing on the user interface on joining.
3424 Affected file silc/client_ops.c.
3426 * Implemented the UMODE command and user modes in general to the
3427 client library and to the user interface.
3429 * Implemented the UMODE command to the server.
3431 * The server now sends UNKNOWN_COMMAND error status if client sends
3432 unknown command. Affected file silcd/command.c.
3434 * All server commands now handle the command identifier the right
3435 way when sending the command reply to the client. The client can
3436 use to identify the command replies with the identifier.
3438 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Added silc_server_get_client_route to resolve the route to
3441 the client indicated by the client ID. Affected file is
3444 * Added silc_server_relay_packet as general function to relay
3445 packet to arbitrary destination. This deprecates functions
3446 like _send_private_message_key, _relay_notify etc. Affected
3447 file is silcd/packet_send.[ch].
3449 Removed silc_server_send_key_agreement,
3450 silc_server_send_private_message_key and
3451 silc_server_packet_relay_notify functions from the file
3452 silcd/packet_send.[ch].
3456 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3457 server. Affected file silcd/packet_receive.[ch].
3459 * Implemented the KILL command to the client. Implemented the
3460 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3461 Affected files lib/silcclient/command[_reply].c and
3462 lib/silcclient/client_notify.c. Implemented the KILL notify
3463 printing in the user inteface.
3465 * Fixed a lot silc_parse_nick memory leaks from the client
3466 library in the file lib/silcclient/command.c.
3468 * Changed the silc_server_send_notify_on_channels's `sender'
3469 argument from SilcSocketConnection to SilcClientEntry to
3470 check the sender as entry and not as connection object and not
3471 to send to the client provided as argument. The affected file
3472 is silcd/packet_send.[ch].
3474 * The notify packets that are destined directly to the client used
3475 to not to be processed by the server. Now changed that and the
3476 server processes all notify packets. After relaying the packet
3477 to the client the notify packet is processed in the server.
3479 * The silc_server_free_client_data now checks whether there is
3480 pending outgoing traffic for the client and purges the data to
3481 the network before removing the client entry.
3483 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3485 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3486 an client is killed from the SILC Network. Updated the protocol
3489 Added new function silc_server_send_notify_killed to the
3490 silcd/packet_send.[ch].
3492 * Added function silc_server_packet_relay_notify to relay notify
3493 packets that are destined directly to a client. In this case
3494 the server does not process the notify packets but merely relays
3495 it to the client. Affected file silcd/packet_send.[ch].
3497 Added also silc_server_packet_process_relay_notify to check
3498 whereto relay the notify. Affected file is
3499 silcd/packet_receive.[ch].
3501 * Implemented the KILL command to the server.
3505 * Added the backup schema desgined last fall to the protocol
3506 specs for everyone to see. The specification is in the
3507 *-spec-xx.txt draft and the packet type definitions for the
3508 backup routers is in *-pp-xx.txt draft. Thusly, added also
3509 new packet type SILC_PACKET_CELL_ROUTERS.
3511 * A big security problem in the implementation discovered. The
3512 signoff of an client did not cause new channel key generation
3513 which it of course should've done. The channel keys must be
3514 always re-generated when client leaves (or signoffs) the channel.
3515 The silc_server_remove_from_channels funtion now handles
3516 the channel key re-generation.
3518 * Added `sender' argument to the silc_server_send_notify_on_channels
3519 to not to send the client provided as argument. Affected file
3520 silcd/packet_send.[ch].
3522 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Implemented OPER and SILCOPER commands into the server and
3527 * Added silc_auth_verify and silc_auth_verify_data to verify
3528 the authentication directly from the authentication payload.
3529 It supports verifying both passphrase and public key based
3530 authentication. Affected file lib/silccore/silcauth.[ch].
3532 * Added `hash' field to the SilcIDListData structure. It is the
3533 hash negotiated in the SKE protocol. Affected file is
3536 * Slight redesigning of the SilcAuthPayload handling routines.
3537 Do not send SilcPKCS but SilcPublicKey as argument.
3539 * Implemented the public key authentication support to the
3540 serverconfig. The public key is loaded from the provided path
3541 and saved as authentication data to void * pointer. Thus,
3542 changed the unsigned char *auth_data to void *auth_data;
3544 * Fixed SHUTDOWN command to send the reply before the server
3545 is shutdown. :) Affected file silcd/command.c.
3547 * Fixed fatal bug in CONNECT command. The hostname was invalid
3548 memory and server crashed. Affected file silcd/command.c.
3550 * Fixed fatal bug in CLOSE command. The server_entry became
3551 invalid but was referenced later in the command. Affected file
3554 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Fixed fatal bug in failure packet handling. Server ignored
3557 the failure and thus crashed when it came.
3561 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3564 that the command may be executed only once in (about) 2 seconds.
3565 The old SILC_CF_LAG flag is same but allows command bursts up
3566 to five before limiting.
3568 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3569 server code. Various commands now includes the CF_LAG_STRICT
3570 flag to disallow any kind of miss-use of the command.
3572 * Fixed the silc_buffer_unformat to not to allocate any data
3573 if the length of the data is zero. It used to allocate the
3574 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3576 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3578 * Changed the format of AdminConnection configuration section
3579 in the server. Added username of the admin to the format.
3580 Affected files silcd/serverconfig.[ch].
3582 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3583 to return admin configuration data by host, username and/or
3586 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3588 * Implemented WHOWAS command to the server. Added the functions:
3590 silc_server_command_whowas_parse,
3591 silc_server_command_whowas_send_reply,
3592 silc_server_command_whowas_from_client and
3593 silc_server_command_whowas_from_server
3595 * Added <Client ID> argument to the WHOWAS command reply. Updated
3596 the protocol specs accordingly.
3598 * Implemented WHOWAS command and command_reply to the client
3601 Implemented the WHOWAS printing on the user interface.
3603 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Added new argument to the WHOWAS command reply, the real name.
3606 It is an optional argument. Updated the protocol specs.
3608 * Added SilcIDCacheDestructor callback that is registered when
3609 the SilcIDCache is allocated. The callback is called when
3610 an cache entry in the ID Cache expires, or is purged from the
3611 cache. Added into lib/silccore/idcache.[ch].
3613 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3614 to destruct the client entries when the cache entry expires.
3615 Other ID Cache's in server and in the client library ignores
3618 * If the ID Cache entry's `expire' field is zero then the entry
3619 never expires. Added boolean `expire' argument to the
3620 silc_idcache_add function in the lib/silccore/idcache.[ch].
3621 If it is TRUE the default expiry value is used.
3623 * Added silc_server_free_client_data_timeout that is registered
3624 when client disconnects. By default for 5 minutes we preserve
3625 the client entry for history - for WHOWAS command.
3627 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3629 * Added support to the server to enforce that commands are not
3630 executed more than once in 2 seconds. If server receives
3631 commands from client more frequently, timeout is registered
3632 to process the commands. Affected file silcd/command.c.
3633 Added new function silc_server_command_process_timeout.
3635 * Changed NICK_NOTIFY handling in client library to check that
3636 if the client's nickname was changed, so there is no need to
3637 resolve anything from the server.
3639 * Removed error printing from the WHOIS and IDENTIFY commands.
3640 If error occurs then it is ignored silently in the client library.
3641 The application, however, may map the received error to
3642 human readable error string. The application currently maps
3643 the NO_SUCH_NICKNAME error to string.
3645 * Made the command status message public to the application. Moved
3646 them from lib/silcclient/command_reply.c to
3647 lib/silcclient/command_reply.h. The application can map the
3648 received command status to the string with the
3649 silc_client_command_status_message function.
3651 * Added check to the server to check that client's ID is same
3652 as the Source ID in the packet the client sent. They must
3655 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Added dist-bzip hook to the Makefile.am to make bzip2
3658 compressed distributions.
3660 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Server now enforces the maximum length for the nickname and
3663 the channel as protocol specification dictates. 128 bytes for
3664 nickname and 256 bytes for channel name.
3666 * Moved the WHOIS printing to the application. The client libary
3667 does not print out the WHOIS information anymore, the application
3668 must do it. Renamed silc_client_command_reply_whois_print to
3669 the silc_client_command_reply_whois_save.
3671 The client's idle time is also sent to the application now, and
3672 the idle is shown on screen.
3674 * Added silc_client_command_reply_identify_save to save the
3675 received IDENTIFY entries.
3677 * Do not check for channel private keys in message sending and
3678 reception if the channel does not have the PRIVKEY mode set.
3679 Affected file lib/silclient/client_channel.c.
3681 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3684 just surfaced after chaning the JOIN procedure.
3686 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Added silc_client_get_clients_by_list to get client entries
3689 from Client ID list, that is returned for example by JOIN
3690 and USERS command replies. The application should use this
3691 function for example when JOIN command reply is received to
3692 resolve the clients already on the channel (library does not
3693 do that anymore as USERS command reply is not used in the JOIN
3694 procedure anymore). Affected files lib/silcclient/silcapi.h and
3695 lib/silcclient/idlist.c.
3697 * JOIN command reply and USERS command reply returns now SilcBuffer
3698 pointers instead of unsigned char pointers when returning
3699 the client list and mode list.
3701 * Added <Client ID> argument to the JOIN command reply, mainly
3702 for the server to identify for which client the command was
3703 originally sent. Updated protocol specs accordingly.
3705 * Added SilcDlist private_key pointer to the SilcChannelEntry
3706 in the client to support the channel private keys. Affected
3707 file is lib/silcclient/idlist.h.
3709 * Added SilcChannelPrivateKey argument to the function
3710 silc_client_send_channel_message so that application can choose
3711 to use specific private ke if it wants to. If it is not provided,
3712 the normal channel key is used, unless private keys are set.
3713 In this case the first (key that was added first) is used
3714 as the encryption key.
3716 * Implemented the support for channel private key handling.
3717 Implemented the following functions:
3719 silc_client_add_channel_private_key,
3720 silc_client_del_channel_private_keys,
3721 silc_client_del_channel_private_key,
3722 silc_client_list_channel_private_keys and
3723 silc_client_free_channel_private_keys
3725 Affected file lib/silcclient/client_channel.c.
3727 * Added the support for the private keys in the channel message
3728 sending and encryption and in the message reception and
3729 decryption. Affected funtions are
3730 silc_client_send_channel_message and silc_client_channel_message.
3732 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added SKE's key verify callback to the client library's
3735 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3737 * Removed the statement that server (or router) must send USERS
3738 command reply when joining to the channel so that the client
3739 knows who are on the channel. Instead, the client list and
3740 client's mode list is now sent in the JOIN command reply to the
3741 client who joined channel. This is better solution.
3743 * Added function silc_server_get_users_on_channel and function
3744 silc_server_save_users_on_channel to the silcd/server.[ch].
3746 * Removed function silc_server_command_send_users from the
3749 * Do not show topic on the client library anymore. The topic is
3750 sent in the command reply notify to the application and the
3751 application must show the topic now.
3753 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Added client searching by nickname hash into the IDENTIFY and
3756 WHOIS commands in the server as they were clearly missing from
3757 them. Affected file is silcd/command.c.
3759 * Fixed a bug in private message receiving in the client library.
3760 The remote ID was freed and it wasn't supposed, now it is
3763 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Minor fix to the channel payload; allocate the data area, as it
3766 needs to be of specific length.
3768 * If the key agreement port is zero then the operating
3769 system will define the bound port. Affected files are
3770 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3772 * Added new function silc_channel_payload_decrypt into the file
3773 lib/silccore/silcchannel.[ch].
3775 * Moved the channel message etc, check from silc_packet_decrypt
3776 to applications. The library calls now a generic
3777 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3778 when the packet is either normal or special. This was done to
3779 allow more wide range of checking that was not allowed when
3780 the code was in library. Now applications can do virtually any
3781 checks to the packet and return to the library the decision how
3782 the packet should be processed. Affected files are
3783 lib/silccore/silcpacket.[ch].
3785 Added silc_server_packet_decrypt_check to the server and
3786 silc_client_packet_decrypt_check to the client library.
3788 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3789 to send with specified source and destination information.
3791 * Channel message delivery between routers was broken after the
3792 channel key distribution was fixed earlier. The channel key
3793 was used be to distributed to other routers as well which is not
3794 allowed by the protocol. Now this is fixed and channel keys
3795 really are cell specific and the channel message delivery between
3796 routers comply with the protocol specification.
3798 * Fixed various commands in server to check also the global list
3799 for the channel entry and not just the local list. The affected
3800 file silcd/command.c.
3802 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Added assert()s to buffer formatting and unformatting routines
3805 to assert (if --enable-debug) when error occurs. Affected
3806 file: lib/silcutil/silcbuffmt.c.
3808 * Changed to auto-reconnect to check whether the remote host is
3809 router and register the re-connect timeout if it is. It used
3810 to check that whether we are normal server, but router must do
3811 auto-reconnect with another router as well. Affected file
3814 * Removed the [<key len>] option from CMODE command as the cipher
3815 name decides the key length, nowadays. See the defined ciphers
3816 from the protocol specification.
3818 * Added [<hmac>] option to the CMODE command to define the HMAC
3819 for the channel. Added SILC_CMODE_HMAC channel mode.
3821 * Added [<hmac>] option for the JOIN command so that user can
3822 select which HMAC is used to compute the MACs of the channel
3825 * Added Hmac field to the Channel Message Payload. The integrity
3826 of plaintext channel messages are now protected by computing
3827 MAC of the message and attaching the MAC to the payload. The
3828 MAC is encrypted. Now, it is clear that this causes some
3829 overhead to the size of the packet but rationale for this is that
3830 now the receiver can verify whether the channel message decrypted
3831 correctly and also when private keys are set for the channel the
3832 receiver can decrypt the packet with several keys and check from
3833 the MAC which key decrypted the message correctly.
3835 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3836 lib/silccrypt/silccipher.[ch].
3838 * Added silc_hash_len to return the digest length into the
3839 lib/silcrypt/silchash.[ch].
3841 * Rewrote parts of Silc Channel Payload interface in the
3842 lib/silccore/silcchannel.[ch]. The encode function now also
3843 encrypts the packet and parse function decrypts it.
3845 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Fixed a minor formatting bug in the SKE's key material processing.
3848 It actually might have processed the keys wrong way resulting
3851 * Redefined the mandatory HMAC algorithms and added new algorithms.
3852 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3853 and hmac-md5 truncated to 96 bits. The mandatory is now
3854 hmac-sha1-96. Rest are optional (including the one that used
3855 to be mandatory). Rationale for this is that the truncated HMAC
3856 length is sufficient from security point of view and can actually
3857 make the attack against the HMAC harder. Also, the truncated
3858 HMAC causes less overhead to the packets. See the RFC2104 for
3861 * Added new [hmac] configuration section. The SKE used to use
3862 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3863 is of course wrong. The official names that must be proposed in
3864 the SKE are the ones defined in the protocol specification
3865 (hmac-sha1-96 for example). The user can configure any hmac
3866 using any hash function configured in the [hash] section. At
3867 least, the mandatory must be configured.
3869 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3871 * Added HMAC list to the SKE proposal list. It has now both
3872 hash algorithm list and HMAC list. This makes the protocol
3873 incompatible with previous versions. The SKE now seems to work
3874 the way it is supposed to work, for the first time actually.
3876 * Defined plain Hash algorithms to the protocol specification.
3879 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3881 * Implemented support for key agreement packets into the server.
3882 Added functions silc_server_key_agreement and
3883 silc_server_send_key_agreement. Other than these functions,
3884 server has nothing to do with this packet.
3886 * Added support for private message key packets into the server.
3887 Added functions silc_server_private_message_key and
3888 silc_server_send_private_message_key.
3892 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3893 called in the protocol's final callback instead in the END
3894 protocol state. This makes a little more sense and in the same
3895 time in client we can use the same protocol routines for normal
3896 key exchange and to key agreement packet handling as well.
3898 * Added to both client's and server's KE protocol context the
3899 SilcSKEKeyMaterial pointer to save the key material. We will
3900 bring the key material to the protocol's final callback by doing
3901 this. The final callback must free the key material.
3903 * Added SKE's packet_send callback into client's KE protocol
3904 context so that the caller can choose what packet sending function
3905 is used. This way we can use different packet sending when
3906 doing normal SKE when doing key agreement packet handling (in
3907 the key agreement packet handling we do not want to encrypt
3910 * Implemented the responder side of the key agreement routines
3911 in the client. The client can now bind to specified port and
3912 accept incoming key negotiation. The key material is passed
3913 to the application after the protocol is over.
3915 * Implemented the processing of incoming Key Agreement packet
3916 in the client. Added function silc_client_key_agreement to
3919 * Implemented the intiator side of the key agreement routines
3920 in the client. The client can now initiate key agreement with
3921 another remote client. The key material is passed to the
3922 application after the protocol is over.
3924 * Created client_keyagr.c to include all the key agreement
3927 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3928 SILC_TASK_CALLBACK except that it is not static.
3930 * Created client_notify.c and moved the Notify packet handling
3931 from the client.[ch] into that file.
3933 * Created client_prvmsg.c and moved all private message and
3934 private message key routines from the client.[ch] into that file.
3936 * Create client_channel.c and moved all channel message and
3937 channel private key routines from the client.[ch] into that file.
3939 * Changed silc_client_get_client_by_id_resolve to resolve with
3940 WHOIS command instead of IDENTIFY command, in the file
3941 lib/silclient/idlist.c.
3943 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3945 * Implemented the SKE's responder side to the Client library.
3947 * When FAILURE is received to the protocol do not trust it
3948 blindly. Register a timeout to wait whether the remote closes
3949 the connection as it should do it, only after that process the
3950 actual failure. This was changed to both client and server.
3952 * Added client_internal.h to include some of the structures
3953 there instead of client.h in lib/silcclient/.
3955 * Added function silc_task_unregister_by_callback to unregister
3956 timeouts by the callback function.
3958 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Some "Incomplete WHOIS info" errors has been appearing on the
3961 log files. Took away the entry->userinfo check from WHOIS
3962 reply sending. The entry->userinfo is now " " if client did not
3963 provide one. I thought this was fixed earlier but something
3964 is wrong still. Let's see if the error still appears.
3966 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3968 * Fixed a minor bug in the login when the channel key is
3969 re-generated in the server. It used to generate the key in
3970 wrong order and thus caused problems in the channel traffic.
3972 * Fixed a minor bug in channel key distsribution after
3973 KICK command. The key was not sent to the router even though
3976 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Added silc_ske_process_key_material_data as generic routine
3979 to process any key material as the SILC protocol dictates. The
3980 function is used by the actual SKE library but can be used by
3981 applications as well. This relates to the private message keys
3982 and the channel private keys since they must be processed the
3983 same way the normal SILC session keys. The protocol dictates
3984 this. Affected files: lib/silcske/silcske.[ch].
3986 Added also silc_ske_free_key_material to free the
3987 SilcSKEKeyMaterial structure.
3989 * Defined silc_cipher_set_key function to set the key for
3990 cipher without using the object's method function. The affected
3991 files: lib/silccrypt/silccipher.[ch].
3993 * Implemented silc silc_client_add_private_message_key,
3994 silc_client_add_private_message_key_ske,
3995 silc_client_del_private_message_key,
3996 silc_client_list_private_message_keys and
3997 silc_client_free_private_message_keys functions in the
4000 Added functions silc_client_send_private_message_key to send
4001 the Private Message Key payload and silc_client_private_message_key
4002 to handle incoming Private Message Key payload.
4004 * Added Cipher field to the Private Message Key payload to set
4005 the cipher to be used. If ignored, the default cipher defined
4006 in the SILC protocol (aes-256-cbc) is used.
4008 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4010 * Removed lib/silcclient/ops.h file.
4012 Redefined parts of the SILC Client Library API. Created new
4013 file silcapi.h that deprecates the ops.h file and defines the
4014 published Client Library API. Defined also private message key
4015 API and channel private key API into the file.
4017 This is the file that the application must include from the
4018 SILC Client Library. Other files need not be included by
4019 the application anymore.
4021 * Added new key_agreement client operation callback and also
4022 defined the Key Agreement library API for the application.
4024 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4026 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4027 is used by clients to request key negotiation between another
4028 client in the SILC network. If the negotiation is started it
4029 is performed using the SKE protocol. The result of the
4030 negotiation, the secret key material, can be used for example
4031 as private message key.
4033 Implemented the Key Agreement payload into the files
4034 lib/silccore/silauth.[ch].
4036 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Redefined ciphers for the SILC protocol. Added some new ciphers
4039 and defined the key lengths for the algorithms. Changed the
4040 code accordingly. The default key length is now 256 bits.
4042 * Fixed SKE key distribution function silc_ske_process_key_material
4043 when the key length is more than 128 bits. The default key
4044 length in SILC is now 256 bits.
4046 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4047 to indicate unsupported algorithm.
4049 * Renamed rijndael.c to aes.c and all functions as well.
4051 * Fixed a long standing channel key setting bug in client library.
4052 Weird that it has never surfaced before.
4054 * Fixed bug in channel deletion. If the entire channel is removed
4055 then it must also delete the references of the channel entry
4056 from the client's channel list as the client's channel entry and
4057 the channel's client entry share same memory.
4059 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Implemented CONNECT and SHUTDOWN commands in the client.
4063 * Implemented CLOSE command to the client.
4065 * Added the function silc_idlist_find_server_by_name into the
4066 files silcd/idlist.[ch].
4068 Added the function silc_idlist_find_server_by_conn into the
4069 files silcd/idlist.[ch].
4071 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * DIE command was renamed to SHUTDOWN. Updated the both code
4076 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4077 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4079 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4082 * Added function silc_server_create_connection function to create
4083 connection to remote router. My server implementation actually
4084 does not allow router to connect to normal server (it expects
4085 that normal server always initiates the connection to the router)
4086 so the CONNECT command is only good for connecting to another
4089 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4092 or some other client was kicked from the channel.
4094 Implemented the handling of the notify type to both client
4097 Implemented silc_server_send_notify_kicked to send the KICKED
4098 notify. It is used to send it to the server's primary router.
4100 * Implemented the KICK command into server and client.
4102 * Added `query' argument to the silc_idlist_get_client function
4103 to indicate whether to query the client from server or not if
4106 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4107 to indicate that the client is not channel founder.
4111 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Removed the rng context from SilcPacketContext structure and
4114 changed that the packet routine uses the Global RNG API.
4116 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4118 * Added support for quit message that client can "leave" on the
4119 channel when it quits the SILC. It is ditributed inside the
4120 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4122 Added silc_server_free_client_data that will take the
4123 signoff message as argument.
4125 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4127 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Updated parts of the protocol specification to keep it up
4132 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4135 payloads in one packet.
4137 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4138 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4139 use now the new List flag.
4141 * Also deprecated the following packet types: REPLACE_ID,
4142 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4144 * Added list support for Notify packet in server.
4146 * Added silc_server_send_notify_channel_change to send the
4147 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4148 the silc_server_send_replace_id.
4150 * Added silc_server_send_notify_nick_change to send the
4151 NICK_CHANGE notify type. Deprecates the function
4152 silc_server_send_replace_id.
4154 * Added silc_server_send_notify_join to send the JOIN notify type.
4155 Deprecates the function silc_server_send_new_channel_user.
4157 * Added silc_server_send_notify_leave to send LEAVE notify type.
4158 Deprecates the function silc_server_send_remove_channel_user.
4160 * Added silc_server_send_notify_cmode and
4161 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4162 types. Deprecates the silc_server_send_set_mode function.
4164 * Added SERVER_SIGNOFF notify type to indicate that server has
4165 quit. This means that all clients on the channel from that
4166 server will drop. This can be also used when netsplit happens.
4168 Deprecated REMOVE_ID packet type since it is not needed anymore
4171 Added silc_server_send_notify_server_signoff to send the
4172 SERVER_SIGNOFF notify type. Deprecates the function
4173 silc_server_send_remove_id.
4175 Added also silc_server_send_notify_signoff to send the
4176 SIGNOFF notify type.
4178 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4179 SILC protocol from this day on. Changed the protocol
4180 specification as well.
4182 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4183 notify type. It is used between routers to notify about
4184 topic changes on a channel.
4186 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4189 * Partly updated the protocol specification to comply with the
4190 changes now made. It is still though a bit outdated.
4192 * The JOIN notify type now takes one extra argument <Channel ID>.
4193 The packet used to be destined to the channel but now the
4194 JOIN type may be sent as list thus it is impossible to
4195 destine it to any specific channel. By adding this argument
4196 it is again possible.
4198 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Added CREDITS file. The CHANGES and CREDITS file will appear
4201 in the distribution as well.
4203 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4206 types in the server's silcd/packet_receive.c.
4208 * Implemented CMODE and CUMODE to work in router environment.
4210 * Fixed minor encoding and decoding buglet from the
4211 lib/silccore/silcmode.c.
4213 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4216 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4218 * Changed all SilcConfigServer* and silc_config_server* to
4219 SilcServerConfig* and silc_server_config*, respectively.
4222 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Associated the ID (client or server ID) to the Authentication
4225 Payload to avoid any possibility of forging. Updated the
4226 protocol specification and the code accordingly.
4228 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4230 * The RSA key length is now save to the RsaKey context in the
4231 key generation process in lib/silccrypt/rsa.c. The key length
4232 is now used to figure out the maximum size of the block allowed
4233 to be encrypted/signed.
4235 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4236 is equivalent to the silc_mp_mp2bin but does not allocate any
4239 * Changed silc_mp_mp2bin API to take length argument. If it is
4240 non-zero then the buffer is allocated that large. If zero, then
4241 the size is approximated using silc_mp_sizeinbase, which however
4244 * Created Global RNG API which is global RNG that application can
4245 initialize. After initializing, any routine anywhere in the
4246 code (including library) can use RNG without allocating a new
4247 RNG object. This was done to allow this sort of use of the
4248 RNG in code that has no chance to allocate RNG object. All
4249 applications currently allocate this and many routines in the
4250 library use this. Affected file lib/silccrypt/silcrng.[ch].
4252 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4253 it to use the Global RNG API.
4255 * Defined Authentication Payload into protocol specification that
4256 is used during SILC session to authenticate entities. It is
4257 used for example by client to authenticate itself to the server
4258 to obtain server operator privileges.
4260 Implemented this payload into the lib/silccore/silcauth.[ch].
4261 Implemented also routines for public key based authentication
4262 as the new protocol specification dictates.
4264 Moved definitions of different authentication methods from
4265 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4267 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4268 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4269 silc_pkcs_verify_with_hash functions into the file
4270 lib/silccrypt/silcpkcs.[ch].
4272 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * The client entry's userinfo pointer must be always valid.
4275 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4276 will fail since it requires the userinfo. Now, the userinfo
4277 is allocated as "" if actual userinfo does not exist. Actually,
4278 it must exist and it is totally Ok to drop client connections
4279 that does not announce the userinfo. However, we will make
4280 this workaround for now.
4282 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4283 to return the remote port by socket.
4285 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4288 SILC_SERVER_PENDING_EXEC and added an new macro
4289 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4290 data or when error occurs while processing the pending command.
4292 Added new argument `destructor' into silc_server_command_pending
4293 and to the SilcServerCommandPending object. This destructor is
4294 now called after calling the pending callback or if error occurs
4295 immediately. If error occurs the actual pending callback won't
4296 be called at all - only the destructor. The destructor may be
4297 NULL if destructor is not needed.
4299 All this applies for client library code as well. Similar
4300 changes were made there as well for the pending commands.
4302 In the client, the application must now allocate the
4303 SilcClientCommandContext with the silc_client_command_alloc
4306 * Added reference counter to the SilcServerCommandContext. Added
4307 function silc_server_command_alloc and silc_server_command_dup
4310 Same type of functions added to the client library for the same
4313 * Removed the cmd_ident from IDListData away since it is now
4314 global for all connections. It is the command identifier used
4315 in command sending and with pending commands. The affected file
4318 * Added reference counter to the SilcSocketConnection objecet to
4319 indicate the usage count of the object. The object won't be
4320 freed untill the reference counter hits zero. Currently only
4321 server uses this, and client ignores it. The client must be
4322 set to use this too later. The affected files are
4323 lib/silccore/silcsockconn.[ch]. Added also the function
4324 silc_socket_dup to increase the reference counter.
4326 This was mainly added because it is possible that the socket
4327 is removed underneath of pending command or other async
4328 operation. Now it won't be free'd and proper DISCONNECTING
4329 flags, etc. can be set to avoid sending data to connection that
4330 is not valid anymore.
4332 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4333 the connection. After that it sets SILC_SET_DISCONNECTED.
4334 It is, however, possible that the socket data is not still freed.
4335 The silc_server_packet_process now checks that data is not
4336 read or written to connection that is DISCONNECTED. The socket
4337 get's freed when the reference counter hits zero.
4339 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Changed the client operation API: channel_message operation's
4342 `sender' is now the client entry of the sender, not the nickname
4343 and the `channel' is the channel entry, not the channel name.
4345 In the private_message operation the `sender' is now also the
4346 client entry of the sender not the nickname.
4348 Affected file is lib/silcclient/ops.h and all applications
4349 using the client operations.
4351 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Moved the calling of ops->connect() from connect_to_server_final
4354 into receive_new_id functin since that is the point when the
4355 client is actually allowed to send traffic to network. The
4356 affected file is lib/silcclient/client.c.
4358 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4361 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4362 (if needs broadcasting) instead of broadcasting the packets one
4363 by one which would make a burst in the network traffic.
4365 * Added `broadcast' argument to the functions in silcd/server.[ch]
4366 silc_server_create_new_channel[_with_id] to indicate whether
4367 to send New Channel packet to primary router.
4369 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4371 * Added new function into the silcd/server.[ch] files:
4372 silc_server_create_new_channel_with_id to create new channel with
4373 already existing Channel ID.
4375 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4376 lib/silccore/silcpacket.h. This packet is used t send list of
4377 Set Mode payloads inside one packet. Server uses this to set
4378 the modes for the channels and clients on those channels, that it
4379 announced to the router when it connected to it. The protocol
4380 specification has been updated accordingly.
4382 * The silc_server_new_channel did not handle the packet coming
4383 from normal server as it normally does not send that. However,
4384 when it announces its channels it does send it. Implemented
4385 the support for that.
4387 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4388 into the file lib/silccore/id.h.
4390 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Fixed memory leaks in the functions silc_idlist_del_client,
4393 silc_idlist_del_channel and silc_idlist_del_server in the file
4394 silcd/idlist.c. All of those leaked like a sieve.
4396 * Fixed some small memory leaks in the client's function
4397 silc_client_notify_by_server.
4399 * Added functions into silcd/server.c: silc_server_announce_clients,
4400 silc_server_announce_channels and silc_server_announce_server.
4401 These functions are used by normal and router server to announce
4402 to its primary router about clients, channels and servers (when
4403 router) that we own. This is done after we've connected to the
4406 These functions effectively implements the following packet types:
4407 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4408 and SILC_PACKET_NEW_ID_LIST.
4410 * Added new functions into the silcd/packet_receive.[ch]:
4411 silc_server_new_id_list, silc_server_new_channel_list and
4412 silc_server_new_channel_user_list to handle the incoming
4413 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4415 * Added support of changing Channel ID in the function
4416 silc_server_replace_id. If the server that announces a channel
4417 to the router already exists in the router (with same name but
4418 with different Channel ID), router is responsible to send
4419 Replace ID packet to the server and force the server to change
4420 the Channel ID to the one router has.
4422 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4423 client that the Channel ID has been changed by the router. The
4424 normal server sends this to the client. Client must start using
4425 the new Channel ID as the channel's ID.
4427 Implemented handling of this new type into lib/silcclient/client.c
4428 into the function silc_client_notify_by_server.
4430 * Added new function silc_idlist_replace_channel_id into the files
4431 silcd/idlist.[ch] to replace the Channel ID.
4433 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Call silc_server_command_identify_check always when processing
4436 the IDENTIFY command in silcd/command.c
4438 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4441 send keepalive packets. The packet can be sent by clients,
4442 servers and routers.
4444 Added function silc_socket_set_heartbeat into the file
4445 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4446 If not set, the heartbeat is not performed. The actual
4447 heartbeat is implemented in the low level socket connection
4448 library. However, application is responsible of actually
4451 Added silc_server_send_heartbeat to send the actual heartbeat
4452 packet into silcd/packet_send.[ch]. Server now performs
4453 keepalive with all connections.
4455 * Added silc_task_get_first function into lib/silcutil/silctask.c
4456 to return the timeout task with shortest timeout. There was a bug
4457 in task unregistration that caused problems. TODO has been
4458 updated to include that task system must be rewritten.
4460 * The client library will now resolve the client information when
4461 receiving JOIN notify from server for client that we know but
4462 have incomplete information.
4464 * Rewrote parts of silc_server_remove_from_channels and
4465 silc_server_remove_from_one_channel as they did not remove the
4466 channel in some circumstances even though they should've.
4468 * Encryption problem encountered in server:
4470 The LEAVE command used to send the Channel Key packet to the
4471 router immediately after generating it. However, the code
4472 had earlier sent Remove Channel user packet but not immediately,
4473 ie. it was put to queue. The order of packets in the router
4474 was that Channel Key packet was first and Remove Channel User
4475 packet was second, even though they were encrypted in the
4476 reverse order. For this reason, MAC check failed. Now, this
4477 is fixed by not sending the Channel Key packet immediately but
4478 putting it to queue. However, this is more fundamental problem:
4479 packets that are in queue should actually not be encrypted
4480 because packets that are sent immediately gets encrypted
4481 actually with wrong IV (and thus MAC check fails). So, packets
4482 that are in queue should be encrypted when they are sent to
4483 the wire and not when they put to the queue.
4485 However, the problem is that the current system has not been
4486 designed to work that way. Instead, the packet is encrypted
4487 as soon as possible and left to the queue. The queue is then
4488 just purged into wire. There won't be any fixes for this
4489 any time soon. So, the current semantic for packet sending
4492 o If you send packet to remote host and do not force the send
4493 (the packet will be in queue) then all subsequent packets to the
4494 same remote host must also be put to the queue. Only after the
4495 queue has been purged is it safe again to force the packet
4498 o If you send all packets immediately then it safe to send
4499 any of subsequent packets through the queue, however, after
4500 the first packet is put to queue then any subsequent packets
4501 must also be put to the queue.
4503 Follow these rules and everything works fine.
4505 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Added new function silc_server_remove_clients_by_server to
4508 remove all client entries from ID list when the server connection
4509 is lost. In this case it is also important to invalidate all
4510 client entires as they hold the invalid server entry. This
4511 fixes fatal bug when server has lost connection and will reconnect
4514 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Made some sanity checks to silc_server_daemonise like to check
4517 whether the requested user and group actually exists.
4519 * Added sanity check to SKE's silc_ske_responder_finish to check
4520 that the public and private key actually is valid.
4522 * Invalidate the client's nickname when receiving Replace ID
4523 packet and the Client ID is being replaced. This means that the
4524 server will query the nickname if someone needs it (client)
4527 * Sort the ID Cache in client library when the ID Cache data
4528 has changed (needs sorting).
4530 * Do not allow for SILC client to create several connections to
4531 several servers. The client does not support windows right now
4532 and generating multiple connections causes weird behaviour.
4534 Irssi-silc client does support windows and can handle several
4535 connections without problems, see: www.irssi.org and SILC plugin.
4537 * Fixed some places where client was added to the IDList. The
4538 rule of thumb is following (in order to get everything right):
4539 If the client is directly connected local client then the
4540 `connection' argument must be set and `router' argument must be
4541 NULL to silc_idlist_add_client function. If the client is not
4542 directly connected client then the `router' argument must
4543 bet set and the `connection' argument must be NULL to the
4544 silc_idlist_add_client function.
4546 * The funtion silc_server_packet_send_local_channel actually did
4547 not check whether the client was locally connected or not. It
4548 does that now. Fixed a bug related to LEAVE command.
4550 * Fixed Remove Channel User payload parsing bug in server's
4551 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4553 * The server's silc_server_save_channel_key now checks also the
4554 global ID list for the channel as it might not be in the local
4555 list. Fixed a bug related to LEAVE command.
4557 * Is this the end of the [<unknown>] buglet that has been lurking
4558 around for a long time? A little for loop fix in server's
4559 silc_server_command_whois_parse that is used by both IDENTIFY
4560 and WHOIS command. At least, this was a clear bug and a cause
4561 of one type of [<unknown>] buglet.
4563 * WHOIS and IDENTIFY commands call the function
4564 silc_server_command_[whois/identify]_check function even if
4565 we are not router server.
4567 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Added --with-gmp configuration option. If set the GMP
4570 is always compiled in the SILC source tree. If not set then
4571 it is checked whether the system has the GMP3 installed. If
4572 it has then the GMP won't be compiled (the system's headers
4573 and library is used), if it doesn't have it then the GMP is
4574 compiled in the SILC source tree.
4576 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4578 * Changed RSA private exponent generation to what PKCS #1
4579 suggests. We try to find the smallest possible d by doing
4580 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4581 not security fix but optimization.
4583 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Added new config entry [Identity] to fork the server and run
4586 it as specific user and group. A patch from Bostik.
4588 * Imported Dotconf configuration library into lib/dotconf.
4589 This will be used to create the SILC configuration files later.
4590 It will appear in the distsribution after this commit.
4592 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * A big code auditing weekend happening. Auditing code for
4595 obvious mistakes, bugs and errors. Also, removing any code
4598 Removed files for being obsolete:
4600 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4601 inline in the file lib/silcutil/silcbuffer.h)
4603 o lib/silcutil/silcbufutil.c (the header has inline versions)
4605 Changed code to fix possible error conditions:
4607 o The buffer formatting routines now check that the destination
4608 buffer really has enough space to add the data. This applies for
4609 both buffer formatting and unformatting
4610 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4611 unformatting was changed to accomodate following rules:
4612 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4613 sent to the function while XXX_*STRING will not allocate or copy
4614 the data into the buffer. Instead it sets the pointer from the
4615 buffer into the pointer sent as argument (XXX_*STRING used to
4616 require that the pointer must be allocated already). This change
4617 makes this whole thing a bit more consistent and more optimized
4618 (note that the data returned in the unformatting with XXX_*STRING
4619 must not be freed now). The routines return now -1 on error.
4621 o Tried to find all code that use buffer_format and buffer_unformat
4622 and added return value checking to prevent formatting and
4623 especially unformatting errors and possible subsequent fatal
4626 o Changed ske->x and ske->KEY to mallocated pointers in
4627 lib/silcske/silcske.h. Fixed possible data and memory leak.
4629 o Added return value checking to all *_parse* functions. Fixed
4630 many memory leaks as well.
4632 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4633 so that buffer overflows would not happen. All code now also
4634 checks the return value as it can fail.
4636 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added reconnection support to server if the normal server looses
4639 its connection to the router (for example if router is rebooted).
4640 The server performs normal reconnection strategy implemented
4641 to the server. Affected file silcd/server.c.
4643 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added new packet type SILC_PACKET_SET_MODE that is used to
4646 distribute the information about changed modes (for clients,
4647 channels and clients channel modes) to all routers in the
4648 network. Updated the protocol specification accordingly.
4650 Added functions into silcd/packet_send.c and
4651 silcd/packet_receive.c: silc_server_send_set_mode,
4652 silc_server_set_mode.
4654 Added new files silcmode.[ch] into lib/silccore that implements
4655 the encoding and decoding of Set Mode Payload. Added new type
4656 SilcSetModePayload. Moved the definitions of different modes
4657 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4659 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Oops, a little mistake in server's connection authentication
4662 protocol. The protocol is not ended with FAILURE but with
4663 SUCCESS if the authentication is Ok. :) Affected file is
4666 * Implemented NICK_CHANGE notify handling in server in the file
4667 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4668 the local clients on the channel. After the changing nickname
4669 in router environment snhould work and the [<unknown>] nickname
4670 should appear no more.
4672 The silc_server_replace_id function that receives the Replace ID
4673 payload now sends the NICK_CHANGE notify type also in the file
4674 silcd/packet_receive.c
4676 * Changed WHOIS and IDENTIFY command to support the maximum amount
4677 of arguments defined in protocol specs (3328 arguments). This
4678 fixed a bug that caused problems when there were more than three
4681 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4683 * Added extra parameter, command identifier, to the
4684 silc_client_send_command so that explicit command identifier
4687 Changed that ID list routines uses specific command identifier
4688 when sending WHOIS/IDENTIFY requests to the server so that they
4689 can be identified when the reply comes back.
4691 Affected files lib/silcclient/command.[ch],
4692 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4694 * Added `sender' argument to silc_server_packet_send_to_channel
4695 to indicaet the sender who originally sent the packet to us
4696 that we are now re-sending. Ignored if NULL. Affected file
4697 silcd/packet_send.[ch].
4699 * Added some server statistics support in silcd/server_internal.h
4700 SilcServerStatistics structure and around the server code. Also
4701 send some nice statistics information when client is connecting
4704 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Fixed channel ID decoding in server's JOIN command reply in
4707 silcd/command_reply.c
4709 * Fixed braodcasting of replace ID payload to not to send it if
4710 we are standalone server in silcd/packet_receive.c.
4712 * Fixed all channel message sending routines to not to send
4713 packets to clients that has router set, since they are routed
4714 separately in the same function earlier. Affects file
4715 silcd/packet_send.c and all channel packet sending functions.
4717 * In USERS reply, res_argv[i] are not allocated, the table
4718 is allocated. Thus changed that free the table, not its
4721 * In server's whois_check and identify_check if the client is
4722 locally connected do not send any WHOIS commands - they are not
4725 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Fixed some minor bugs in client when sending WHOIS command. The
4728 arguments was in wrong order.
4730 * Removed statis function add_to_channel from server in
4731 silcd/command.c that was previously used with the joining but
4734 * Tested USERS command in router environment successfully with two
4735 routers, two servers and two clients.
4737 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Reorganized the USERS command and command reply in client library
4740 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4741 When the command is given by user we register a pending command
4742 callback that will reprocess the command after the reply has been
4743 received from the server. When reprocessing the packet we then
4744 display the information. Thus, the USERS information is displayed
4745 now in the command callback instead of in the command reply
4746 callback. The processing of the command is same as previously
4747 when server has sent the command reply in the JOINing process.
4749 * Added to USERS command in silcd/command_reply.c to join the client,
4750 we didn't use to know about, to the channel after we've created
4751 a client entry for it. Also, for clienet we did know already still
4752 check whether it is on the channel or not and add it if not.
4754 * Removed silc_server_command_join_notify as the function and its
4757 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Changed the client's pending command handling to the same as the
4760 server's pending command handling. It is also now possible to
4761 execute command reply functions from other command reply
4762 function as the function callbacks for commands and command
4763 replies are one and same. The pending commands are not static
4764 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4765 in client connection context. Thus, pending commands are server
4766 connection specific as it is convenient.
4768 Changed the function silc_client_command_pending and
4769 silc_client_command_pending_del and added new function
4770 silc_client_command_pending_check. Removed the
4771 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4774 * Added cmd_ident, current command identifier, to the client
4775 connection context in lib/silcclient/client.h to keep track on
4776 command identifiers used in command sending. Client's command reply
4777 function handling now supports the mandatory command identifiers.
4779 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4780 funtions in client to fully support pending command callbacks.
4782 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4783 as one of the arguments to the application in the command reply
4786 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4787 before first releasing SILC but came back. Now it is removed again
4788 and should come back nomore. The FORWARDED flag was used only
4789 by the JOINing procedure by forwarding the command packet to router.
4790 Now, the JOINing procedure has been changed to more generic (due
4791 to various router environment issues) and FORWARDED is not needed
4792 anymore for anything. The protocol specification is yet to be
4795 Now, removed silc_server_packet_forward from server and the flag
4796 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4798 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Renamed NAMES command to USERS command. The NAMES was named that
4801 due to historical reasons. Now it is renamed. Also, rewrote
4802 parts of the USERS command. The nickname list is not sent anymore
4803 by the server. Only Client ID and mode lists are sent in the USERS
4804 command. Changed this also to the protocol specification.
4806 The client now resolves the names and stuff after it receives
4807 the USERS list from the server when joining to the channel.
4809 * WHOIS and IDENTIFY commands has been changed to support multiple
4810 Client ID's per command. One can now search for multiple users
4811 in the network by sending only one WHOIS or IDENTIFY command.
4812 Changed the code and the protocol specifications.
4814 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4815 uses silc_server_command_whois_parse to parse the request. */
4817 * If normal server, do not parse the WHOIS and IDENTIFY requests
4818 before sending it to the router. Saves some time.
4820 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Fixed JOIN command on client library. Wrong number of arguments
4823 used to crash the client.
4825 * Added silc_server_channel_has_global function to check whether
4826 channel has global users or not.
4828 * Added silc_server_channel_has_local function to check whether channel
4829 has locally connected clients on the channel.
4831 * The silc_server_remove_from_one_channel now checks whether the
4832 channel has global users or not after given client was removed from
4833 the channel. It also checks whether the channel has local clients
4834 on the channel anymore. If it does not have then the channel entry
4835 is removed as it is not needed anymore.
4837 * The silc_server_notify now checks on JOIN notify whether the joining
4838 client is one of locally connected or global. If it is global then
4839 the channel has now global users on the channel and that is marked
4840 to the channel entry. Also, it now saves the global client to
4841 global list who is joining and JOINs it to the channel. This is
4842 for normal server, that is.
4844 Changed silc_server_send_notify_on_channel,
4845 silc_server_packet_relay_to_channel and
4846 silc_server_packet_send_to_channel check if we are normal server
4847 and client has router set (ie. global client) do not send the
4848 message to that client, as it is already routed to our router.
4850 * Implemented LEAVE notify type handling in silc_server_notify
4853 * Tested LEAVE command in router environment successfully. Tested
4854 with two routers, two servers and two clients.
4858 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4860 * Implemented SIGNOFF notify type handling in silc_server_notify
4863 * silc_server_remove_id now removes the client entry from all channels
4864 it has joined and thusly sends SIGNOFF notify type.
4866 * Rewrote the NAMES list generation in server by removing two excess
4867 loops. The lists are created now inside one loop.
4869 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4871 * silc_server_remove_channel_user checks now also global list
4872 for channel and client.
4874 * silc_server_new_channel_user checks now both local and global
4875 list for channel and client. Fixed a bug in client id decoding.
4876 Used to decode wrong buffer.
4878 * silc_server_channel_message checks now both local and global
4879 list for channel entry.
4881 * Tested channel joining (hence JOIN) in router environment
4882 successfully. Tested with two routers, two servers and two
4885 * Tested channel message sending in router environment successfully.
4887 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4889 * Added silc_server_save_channel_key into server.[ch] to save the
4890 received channel key in Channel Key payload processing. It is
4891 also used in JOIN command reply handling.
4893 Equivalent function silc_client_save_channel_key added into
4894 client.[ch] into client library.
4896 * Changed JOIN command reply to send information whether the channel
4897 was created or not (is existing already) and the channel key
4898 payload. Changed protocol specs accordingly.
4900 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4901 the request was sent by ID and not by nickname. Crashed on
4904 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4907 now correctly save the received data.
4909 * silc_server_free_sock_user_data now notifies routers in the
4910 network about entities leaving the network.
4912 At the same time implemented functions silc_server_remove_id
4913 and silc_server_send_remove_id to receive and send REMOVE_ID
4914 packets. The packet is used to notify routers in the network
4915 about leaving entities. The ID removed will become invalid in
4918 * Added function silc_idlist_del_server into server. Removes and
4919 free's server entry from ID list.
4921 * silc_server_private_message function now checks, if we are router,
4922 that the destination ID really is valid ID, naturally.
4924 * In router when NEW_ID packet is received (for new client) the
4925 hash of the Client ID is saved in the ID Cache but the
4926 client->nickname is set to NULL, instead of putting the hash
4929 IDENTIFY command now also checks that client->nickname must be
4930 valid. If it is not if will request the data from the server who
4931 owns the client. Added new function
4932 silc_server_command_identify_check.
4934 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4935 to set the command to already allocated Command Payload.
4937 * Tested private message sending in router environment with two
4938 routers, two servers and two clients. Fixed minor bugs and now
4941 * Fixed segfault from client's NAMES command. Used to crash if
4944 * Forwarded packets must not be routed even if it is not destined
4945 to the receiver. Changed server code comply with this.
4947 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added `require_reverse_mapping' boolean value to ServerParams
4950 structure. If TRUE (not default) the server will require that
4951 the connecting host has fully qualified domain name.
4953 If the reverse mapping is not required and hostname could not be
4954 found the IP address is used as hostname.
4956 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Implemented version string checking to both client and server.
4959 The check is incomplete currently due to the abnormal version
4960 strings used in development version of SILC.
4962 * Changed all command functions in server to use the new
4965 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Changed char *data to unsigned char *data in ID Cache system to
4968 support binary data as ID Cache data. Changed code to support
4969 binary data in lib/silccore/idcache.c.
4971 * Renamed silc_server_packet_relay_command_reply to
4972 silc_server_command_reply as it is normal packet receiving
4973 function. Rewrote the function to accept command replys for
4974 servers and not only for clients.
4976 * Mark remote router always as registered server if we are connecting
4977 to it. Otherwise, commands sent by the router to us are ignored.
4979 * All ID List find routines now returns the ID Cache Entry pointer
4980 as well if requested.
4982 * WHOIS command works now in router environment, tested with two
4983 routers, two servers and two clients.
4985 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4986 in router environment (as it is almost equivalent to WHOIS) but
4987 hasn't been tested thoroughly. Added new functions:
4989 silc_server_command_identify_parse
4990 silc_server_command_identify_send_reply
4991 silc_server_command_identify_from_client
4992 silc_server_command_identify_from_server
4994 * Disabled route cache adding because adding two different ID's with
4995 same IP replaces the old cache entry thus giving wrong route.
4996 The entry->router->connection is always the fastest route anyway
4997 so route cache may not be needed. Of course, new routes maybe
4998 established after receiving the ID when the entry->router->connection
4999 might not be anymore the most optimal.
5001 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5003 * Add route cache for received ID for fast routing.
5005 * Added silc_server_packet_route to route received packet on router
5006 that is not destined to us.
5008 * Renamed silc_server_get_route to silc_server_route_get.
5010 * Added id_string and id_string_len fields into SilcServer to
5011 include encoded ServerID for fast comparing without excess
5012 encoding of the ID's.
5014 * Cleaned up WHOIS command on server side. Added following static
5017 silc_server_command_whois_parse
5018 silc_server_command_whois_check
5019 silc_server_command_whois_send_reply
5020 silc_server_command_whois_from_client
5021 silc_server_command_whois_from_server
5023 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5024 arguments in command replies. All command functions should be
5025 updated to use this macro.
5027 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5029 * Minor typo fixes on command reply handling on server.
5031 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added silc_server_command_add_to_channel internal routine to add
5034 the client to the channel after router has created the channel and
5035 sent command reply to the server.
5037 * Added generic silc_server_send_command to send any command from
5040 * Use static buffer with ID rendering instead of duplicating data.
5042 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Fixed a channel user mode bug when joining to a channel server gave
5045 everybody channel founder rights, oops.
5047 * We mark ourselves as the router of the incoming server connection
5048 if we are router ourselves. This way we can check in some packet
5049 sending functions whether it is locally connected server. For
5050 incoming router connections we put NULL.
5052 * For router sending packets locally means now always sending the
5053 packet cell wide; to local clients and local servers. For normal
5054 server sending packet locally means sending it to only local
5057 * Fixed the JOIN command to really work in router environment. If the
5058 channel is created it is always created by the router. Router is
5059 also responsible of making the initial joining to the channel,
5060 sending JOIN notify to the sending server and distributing
5061 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5062 does not exist server doesn't do anything else but forward the
5063 command to the router which performs everything.
5065 * Added silc_server_send_channel_key function to send the Channel Key
5068 * Added silc_server_create_channel_key to create new channel key. The
5069 channel key is now re-generated everytime someone joins or leaves
5070 a channel, as protocol dictates. Note: channel->key_len is the
5073 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5076 packet_receive.[ch] to separate packet sending and receiving
5077 routines. The server.[ch] now includes everything else including
5078 actual packet processing (writing and reading data) and other
5081 Renamed silc_server_private_message_send_internal to
5082 silc_server_send_private_message. The routine is still though
5083 used only to relay private messages as server does not send
5084 private messages itself.
5086 Renamed silc_server_new_channel to silc_server_create_new_channel
5087 and added new function sicl_server_new_channel that handles the
5088 incoming New Channel packet. Added also new sending function
5089 silc_server_send_new_channel to send New Channel Payload.
5091 * Added new function silc_server_notify to process incoming notify
5092 packet to the server/router. Server may then relay the notify
5093 to clients if needed.
5095 * Added new function silc_server_new_channel_user to process incoming
5096 New Channel User packet. Router will redistribute the packet and
5097 send JOIN notify to its local clients and locally connected servers
5098 if needed. Normal server will send JOIN notify to its local client
5099 on same channel when received this packet. Added also corresponding
5100 sending function silc_server_send_new_channel_user to sent the
5103 * Added boolean route argument to send_notif_to_channel and
5104 packet_send_to_channel functions to attempt to route the packet
5105 if it is TRUE and send only locally if it is FALSE.
5107 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * silc_server_replace_id now broadcasts the received replace ID
5110 packet if it is not broadcast packet already. The router must
5111 broadcast to inform other routers about changed ID.
5113 * Added backpointer to server's router into SilcServer context in
5114 silcd/server_internal.h.
5116 * Fixed silc_server_packet_broadcast to send correct broadcast
5119 * The channel key is now distributed to the local client as soon
5120 as it is received from the router (in router environment) so that
5121 no other packet may be sent for the channel until client has
5124 * silc_server_remove_channel_user now broadcasts the received
5125 Remove Channel User packet if it is not broadcast packet already.
5126 The router must broadcast to inform other routers about removed
5129 * Added users field into SilcPacketContext that is a reference count
5130 of the context. One can increase the reference count by calling
5131 silc_packet_context_dup which is now changed to just increase the
5132 reference count instead of duplicating the data. The reference
5133 count is decresed by calling silc_packet_context_free that will
5134 free the data after the reference count hits zero.
5136 For now on the packet context and everything allocated into it
5137 (including the raw packet from network) must be freed by calling
5138 the new silc_packet_context_free function. Added also new function
5139 silc_packet_context_alloc that must be used now to allocate the
5140 context. This also means that if a routine is asynchronous from
5141 silc_[client/server]_packet_parse_type the packet context must
5142 be duplicated by calling silc_packet_context_dup. Otherwise it
5143 gets free'd after silc_[client/server]_packet_parse_type returns.
5144 Also, one must remember that if packet is duplicated then its
5145 reference count must be decresed by calling the free function as
5146 many times as it was duplicated.
5148 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5149 from both client and server.
5151 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Made joining to a channel working in router environment.
5155 * Cleaned up JOIN command on server side and create function
5156 silc_server_command_join_channel internal routine to make the
5159 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5161 * Changed silc_command_pending list to SilcDList. Also, added
5162 `ident' field to SilcServerCommandPending structure to identify
5163 the reply and to call correct callback.
5165 Added silc_server_command_pending_check function to replace the
5166 corresnponding macro. The silc_command_pending list is not
5169 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5170 to set identifier to previously allocated Command Payload. It
5171 is used to set identifier for command when resending Command
5174 * Added silc_command_payload_encode_payload to encode Command
5175 Payload buffer from SilcCommandPayload structure.
5177 * Added silc_argument_payload_encode_payload to encode Argument
5178 payload buffer from SilcArgumentPayload structure.
5180 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5182 * Changed WHOIS command to support router connection on server side.
5183 The whois request is always sent to router unless the server is
5184 standalone server. After server has received the reply from the
5185 router will it send the reply to the client.
5187 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5188 broadcast received broadcast packet. The function is used only
5189 by router. The broadcast packet is always sent to the router's
5192 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5193 render given ID to printable string, for log files for example.
5195 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Made basic router to router connections working. At least they
5198 can now connect to each other but nothing really works the way
5199 they are supposed - yet.
5201 * Added new initiator token to RouterConnection configuration
5202 file in silcd/serverconfig.[ch]. It is used to tell whether we
5203 are the initiator to the remote router or whether we'll expect
5204 the other end to connect.
5206 * Moved registering of listener task to silc_server_init, hence
5207 the server starts listenning as soon as it is run, even if it
5208 does not have connections to other routers. Let's see how well
5211 * Changed default connection retry timeouts for more suitable in
5214 * Removed cipher and such arguments from silc_idlist_add_client
5215 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5216 Added new function silc_idlist_add_data to add the keys and stuff
5219 * Added SilcIDListData structure and added it to SilcClientEntry
5220 and SilcServerEntry as their first field in the structure. This
5221 way we can explicitly cast the ID entries to the SilcIDListData
5222 structure and get common data for the entries. In past, we had
5223 to first check what type of connection it is and then cast it to
5224 correct ID entry type. Now, we can directly cast the opaque
5225 pointer to the SilcIDListData (no matter what ID entry it actually
5226 is) and get the data needed.
5228 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5231 in some circumstances even if threre were timeout tasks, though not
5232 IO tasks, but tasks anyway. Now fixed.
5234 * Defined SilcServerConnection structure to hold connection specific
5235 stuff about directly connected servers and routers. The definition
5236 is currently in silcd/server_internal.h. I thought about having
5237 a bit more important role fro this struct but for now it is used
5238 only when connecting to other server (or router actually).
5240 * Added connecting retry support in server when connecting to
5241 router(s). The retry feature implement exponential backoff
5242 algorithm. Also, added SilcServerParams structure to hold default
5243 parameters for server. For now, it include these retry settings
5244 and are hard coded. After server is moded to be as Silc Server
5245 Library this structure will be more important.
5247 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Changed client librarys channel->clients table to SilcList and
5250 changed code accordingly.
5252 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Changed client's channel table to SilcList and changed code
5255 accordingly. Also changed SilcChannelClientEntry to include back-
5256 pointer to the channel so that client entry can use that structure
5257 as list as well and we have fast cross-reference to the channel.
5258 This change dramatically decreased the complexity of channel
5259 handling with client entry and vice versa (removed one extra
5260 loop when searching for channel entry from many functions).
5262 * Changed server->sim from table to SilcDList and changed code
5265 * NAMES command can now be used from user interface. It will show
5266 the user list on the channel, neatly.
5268 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5269 Code now saves realname of the user if it becomes available.
5271 * Renamed configure.in to configure.in.pre and made ./prepare
5272 script to automatically add correct version string to
5273 configure.in which it creates from configure.in.pre.
5275 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5277 * NAMES command reply now shows users mode with the nickname when
5280 * Moved silc_client_ch[u]mode[_char] functions from
5281 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5282 place sucks, they are utility functions and should be in some
5285 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5287 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5290 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5294 * Added TRQ (efficient deque and list library) into lib/trq. This is
5295 a very good list library that is currently used in the SILC. Defined
5296 SilcList API over the library because I didn't like the API very
5297 much. See lib/trq/silclist.h for the API and examples of how to
5298 use the API. Fixed various places in the code to use the new
5299 SilcList API. The SilcList is meant for lists that has a structure
5300 already defined as a list. It is not suitable to add just some
5301 context to the list (in TRQ, the context is the list actually).
5303 So, I defined SilcDList that can be used for the purpose where
5304 predefined list structure does not exit. This can be used as
5305 such list. Now some context just can be added to the SilcDList.
5306 Currently this list is not used in the SILC just yet, though there
5307 are a lot places where this can replace dynamically allocated
5308 tables and I will fix these places, later, to use SilcDList.
5309 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5310 and use TRQ internally).
5312 Also fixed some annoying warning messages that the original TRQ
5313 code generated. Also minor changes to TRQ's Makefile.in.
5315 * Added support for querying by Client ID to both WHOIS and
5316 IDENTIFY commands into server, as required by the protocol.
5318 * Removed method function pointers from SilcBuffer structure. They
5319 weren't used to anything and just increased the context size for
5320 no good reason. This change also made silc_buffer_alloc and
5321 silc_buffer_free functions inline functions.
5323 * Disabled command flooding detection support until it's fixed so
5324 that it accepts commands in but does not execute them more than once
5327 * Added silc_net_localhost(), to return local hostname, into
5328 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5329 that must be initialized before calling silc_client_init.
5331 * Added new function: silc_server_send_notify_on_channels to send
5332 notify messages to all channels client has joined. It is assured
5333 that the message is sent only once per client.
5335 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5336 lib/silcutil/silcutil.[ch] as silc_format function. The new
5337 function is generic and is used by server as well, not only by
5338 the logging routines.
5340 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5341 the provided version string was not acceptable. Added new function:
5342 silc_ske_check_version into lib/silcske/silcske.h. The function
5343 must be implemented by the application (client or server) and it
5344 does not reside in the SKE library. The function checks the version
5345 string remote end sent.
5347 * Added back pointers (to opaque context and to SilcSocketConnection)
5348 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5350 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5351 duplicate packet context structure.
5353 * Changed `notify' client operation to send same arguments as client
5354 receives from server except for ID's. ID's are mapped to correct
5355 ID entry and that is returned. Also, if channel entry is not sent
5356 by server but the notify is for channel the channel entry is sent
5357 to application (otherwise application doesn't know that it is for
5358 channel (library gets it from packet's Destination ID)).
5360 * Added silc_client_remove_from_channels into client library to
5361 remove a client from all channels it has joined to. Used when
5362 received SIGNOFF notify from server. Added also new function
5363 silc_client_replace_from_channels to replace old ID entry with
5364 new ID entry on all channels. Used when received NICK_CHANGE
5367 * Fixed ID Cache list handling in silc_idlist_get_client in
5368 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5369 to get (or query) client by ID.
5371 * Updated TODO list.
5373 * Added connection authentication status message defined by the
5374 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5375 support for these into the code in client and server side.
5377 * Added generic function silc_client_send_command to send any command
5378 with variable argument list. Application should use this function
5379 to send commands if the command functions provided by the library
5380 does not suite for the application's user interface needs.
5382 * Added new `failure' client operation. Application is notified about
5383 received failure packet if client is executing a protocol. In this
5384 case the protocol's execution has failed.
5386 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5387 is required by the protocol.
5389 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5390 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5393 * Added status flag to SilcSKE object to indicate realtime status
5394 of the SKE protocol.
5396 * Application receives now exactly same command reply arguments as
5397 the library receives from server. However, if ID is received the
5398 corresponding ID entry is returned to the application (eg. Client
5399 ID is mapped to correct SilcClientEntry entry and that is returned).
5400 Changed command_reply client operation due to this change.
5402 * Changed all ID's in commands and in command replys as ID Payloads.
5403 Change affected both client and server side codes.
5405 All ID's sent in SILC network (with execption of ID's in SILC
5406 Packet header) are sent in ID Payload to support variable length
5409 * Server now notifies nick changes and notifies all clients on
5410 the channels about the new nickname (about the new Client ID,
5413 * Implemented CMODE command to change channel modes. Supports all
5414 channel modes defined by the protocol specs except ban and invite
5415 lists. (Also, private channel key mode is supported but support for
5416 setting private channel key in client is missing, thus, this mode
5417 has no effect on client side (except that server requires that the
5418 client uses private channel key and normal channel traffic does not
5421 Also, invite mode works per se, but INVITE command does not work
5422 yet correctly, so you can set channel as invite only channel but
5423 inviting clients to the channel does not work (it is yet to be
5424 thought what's the best way to do it).
5426 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5427 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5428 Implemented CUMODE command to change user's mode on the channel.
5429 Supports all modes defined by the protocol specs.
5431 * Added NAMES command reply to return users modes on the channel.
5433 * Removed unnecessary and slow ciphers from lib/silccrypt.
5435 * Set SO_KEEPALIVE option to connection sockets by default.
5437 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5439 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5440 redefined the Notify Payload into protocol specs.
5442 * Added silc_id_payload_parse_id to get ID directly from raw
5445 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5448 accept searching by Client ID as well.
5450 * Added support for LEAVE and SIGNOFF notify types in client library.
5452 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5453 to parse ID Payload from raw data.
5455 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added flags parameter into silc_ske_assemble_security_properties
5458 function in lib/silcske/silcske.[ch].
5460 * Changed notify client operation to fit better for notify messages
5461 sent by server. The notify payload received from server is now
5462 passed to the application (after parsing it to SilcNotifyPayload).
5463 It is application's responsibility to retrieve the arguments
5464 from the payload and show the message the way it wants. The message
5465 sent by server is implementation specific.
5467 * Changed public keys to comply with the protocol specification.
5468 Old public keys are not supported anymore and are not compatible.
5470 * Removed nickname from Channel Payload as the latest draft removed
5471 it. The client must resolve the nickname from the NAMES command
5472 reply received when it joined the channel.
5474 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5476 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Fixed some errors in protocol specification drafts.
5480 * Created lib/silccore/silcnotify.c to implement Notify Payload
5481 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5482 generic payloads described by protocol specifications. The file
5483 includes implementations for ID Payload and Argument Payload.
5485 * Changed Command Payload implementation to use the new Argument
5486 Payload. Changed command_xxxx_payload to command_payload_xxxx
5487 to comply with SILC coding conventions.
5489 * Added suppport for Argument Payload handling in Notify Payload
5490 implementation as protocol requires it. Added the new support
5491 into server and client lib as well.
5493 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Added support for multiple nicknames on same channel. [n] is
5496 added locally to the nickname if there are more than one same
5497 nicknames on the channel.
5499 * Server now sends all nicknames that matched WHOIS request.
5500 Client also shows the list received from server.
5502 * Added TOPIC command to client side. User can now set and show
5503 current topic on channel.
5505 * Added MOTD command to client and server. Also, server sends the
5506 motd when client connects to the server.
5508 * Changed version strings to comply ISO 8601.
5510 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Fixed protocol error handling in client library. It should now
5513 cope even if the SKE fails for some reason.
5515 * Made new protocol specification drafts for submitting to IETF.
5517 * Implemented TOPIC command to server in silcd/command.c.
5519 * Added two new notify types into lib/silccore/silcnotify.h:
5520 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5521 notify nickname change and topic setting/change on a channel.
5523 * API change of command_reply operation in client library. The
5524 application gets now the status type received from server as well.
5526 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5530 * Cras fixed and optimized the packet handling even further and
5531 it should work now. Minor change to the prototype of function
5532 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5534 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Added new function into lib/silcutil/silcschedule.[ch]:
5537 silc_schedule_with_fd to select() a specified fd. The function
5538 returns after timeout expires or data arrives or goes. The
5539 function is used by packet routines to wait that all data is
5540 received from network.
5542 * Fixed data reading from network in lib/silccore/silcpacket.c.
5543 The code now assures that all data is read from the fd and then
5544 continues packet processing. This was a bug fix since the code
5545 used to drop some data in some circumstances.
5547 * Added new function into lib/silcclient/client.[ch]:
5548 silc_client_start_key_exchange to start key exchange after
5549 connection has been established to server. The code internally
5550 now uses this funtion but its main purpose was to provide it
5551 for applications that perform their own connecting. After
5552 application has created a connection it merely calls this
5553 function to start the key exchange between client and server.
5554 The library takes care of everything else after that.
5556 Updated also lib/silcclient/README to explain the usage of
5559 * Do not send to application information that connection has
5560 been established. Application gets notified it by connect
5563 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Applied cras's patch to add silc_schedule_one function. The
5566 function runs scheduler once and returns.
5568 * Fixed the scheduler after cras messed it up. The timeout
5569 handling works now as it's supposed to work.
5571 * Added into lib/silccore/ silcnotify.h to include notify
5572 message types support. Changed silc_server_send_notify*
5573 functions, in server.[ch], to support those new notify types.
5574 Added the support for the notify types into client library,
5575 as well. Added new notify client operation into ops.h in
5578 * Changed silc_server_packet_send_to_channel to send normal
5579 packets instead of just channel message packets. The function
5580 is now used to send the notify packets to channels. It is not
5581 used to send channel message packets anymore, as server never
5584 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5585 va_arg()s as it seems to require it nowadays. I guess, if SILC
5586 is compiled with older va_arg() the new code should work anyway.
5588 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5590 * Splitted core library. Core library (lib/silccore) includes
5591 now only SILC protocol specific core (and common) components.
5592 Created new utility library (lib/silcutil) that includes more
5593 generic purpose stuff. The stuff for util library was taken
5594 from the old core library. This was minor and easy split.
5596 * Created SILC Client Library (lib/silcclient) that includes
5597 implementation of the SILC client without user interface. This
5598 was major move from silc/ directory. The code has been changed
5599 so that it is transparent towards the user interface. The
5600 silc/ directory includes now the same user interface as before
5601 and it uses the new client library. Read lib/silcclient/README.
5602 Basicly, the client library performs everything else related
5603 to SILC except user interface handling. Also, configuration
5604 files are considered to be part of user interface and library
5605 does not handle them.
5607 This change also changed a lot of structures, function naming etc.
5608 Most important change was that SilcClientWindow object was
5609 renamed to SilcClientConnection in the client library. Created
5610 also new file lib/silcclient/ops.h. Also added new files
5611 silc/local_command.[ch] and silc/client_ops.[ch].
5613 All these changes were made to make it easier for user interface
5614 designers to create what ever user interface for the SILC client
5617 It is also expected that the server will be moved to lib
5618 directory as well and SILC Server Library will be created;
5619 sometimes in the future.
5621 * Removed Local commands from lib/silccore/silccommand.h as
5622 they are application specific and new client library does not
5623 handle any of those anymore.
5625 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5626 old client implementation in silc/.
5628 * Added support for callback functions in SILC_LOG_* macros.
5629 Application can now set its own callbacks that will be called
5630 instead of using the default functions that will always print
5631 the debug messages to stderr (or stdout). Also, debugging can
5632 now be disabled by setting silc_debug to FALSE and re-enabled by
5633 setting it to TRUE. Note, that logging will still work even
5634 if debugging is disabled.
5636 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5637 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5638 silc_log_reset_debug_callbacks.
5640 * To enable debugging in silc client one must give now -d
5641 option on command line.
5643 * Changed silc_schedule_init to automatically allocate task queues
5644 if they are not allocated before calling it.
5646 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Added GMP 3.1 into math library.
5650 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5653 a channel in SILC network. The packet is used by servers and
5654 routers to notify other routers that user has left a channel.
5655 This little feature was missing until now. Added the feature
5656 to protocol specification as well.
5658 Added functions: silc_server_send_remove_channel_user and
5659 silc_server_remove_channel_user into server.[ch].
5661 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5662 lib/silccore/silcpacket.h. However, they are not implemented
5665 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Fixed joining to a channel and sending channel messages
5668 between server and router. The channel message sending should
5669 now work inside a cell.
5671 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Fixed the private message sending between server and router.
5674 The private message sending should now work inside a cell.
5676 * Added silc_server_replace_id into server.[ch] to replace
5677 existing ID in the SILC network.
5679 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5680 and silc_idlist_replace_server_id into idlist.[ch] in server.
5682 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Fixed the server to server connections. Server can again now
5685 connect to router. Router to router connections probably does
5688 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added dynamic protocol registering support. Now protocols can
5691 registered and unregistered on the fly. Patch by cras.
5693 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Added lib/contrib directory to hold routines that some platforms
5696 don't have but are needed by SILC.
5698 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5699 into lin/contrib to provide getopt() and getopt_long() for
5700 those who don't have it.
5702 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5704 * Added AWAY command to client. When away message is set and
5705 client receives a private message packet the client automatically
5706 replies to the sender with the away message.
5708 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5709 bug seemed to be the cause of recent problems when compiling
5712 * Added version detection support to SKE protocol specification
5713 and added the new changes to the SKE implementation as well.
5714 There were other minor changes in the SKE protocol as well.
5716 Many changes in lib/silcske/silcske.[ch] and in
5717 lib/silcske/payload.[ch].
5719 * Added ^U functionality, clear input line. Patch from cras.
5721 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Mainly small bugfixes on core library. Fixed some debugging
5724 logging and buffer overflow in silclog.c.
5726 * Updated config.sub and config.guess on the distribution tree.
5728 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Added command lagging support in server. Client may execute
5731 commands now only once in two seconds.
5733 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Optimized packet reception. MAC computation and checking is now
5736 also more optimized. A lot previously duplicated code is now
5737 used as generic by both client and server.
5739 * Fixed key pair generation in clientutil.c
5741 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5743 * Added into lib/silccore/silcbufutil.[ch] new function;
5744 silc_buffer_realloc.
5746 * Moved generic packet sending/encryption functions to
5747 lib/silccore/silcpacket.[ch] from client and server. Some
5748 rewriting of the functions.
5750 * Moved all generic packet reception/decryption functions to
5751 lib/silccore/silcpacket.[ch] from client and server. The
5752 packet processing is now much cleaner in both client and server.
5753 These were major changes in both client and server.
5755 * Created many common functions in server to do packet sending.
5756 Previously code were duplicated a lot, this has been removed
5759 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Rewrote major parts of the ID cache system. Don't know
5762 whether it is better now or not but at least the API is more
5765 * Major rewrite on ID cache stuff on client because of the ID
5766 cache API changes. Added idlist.c to client.
5768 * Also major rewrite on ID cache stuff on server as well.
5769 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5770 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5771 in hand, instead they are all put into the ID cache system now.
5772 All server_idlist_* routines uses ID cache now instead of
5773 traversing its own lists (those lists does not exist anymore).
5774 SilcIDList though still exists. Also, SilcXXXEntry's are
5777 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Finally made the SKE implementation compliant to the protocol
5780 specification. All mp integers are now binary encoded as
5781 opposed being HEX encoded.
5783 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5786 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5787 functions: silc_[encode/decode]_pem. Also added function
5788 silc_encode_pem_file to PEM encode with newlines ('\n') for
5791 * SILC public keys are now encoded either PEM or binary. Same
5792 option is for private keys as well. By default private keys
5793 are binary encoded and public keys PEM encoded. Silly HEX
5794 encoding were removed.
5796 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5797 function to create fingerprints.
5799 * Fixed a bug in SHA1; does not change the original data anymore.
5801 * Partly implemented INFO command on client and server side.
5802 Fixed CLEAR command. Changes to SERVER command; show current
5803 server(s) when giving command without arguments. Added
5804 VERSION command to client.
5806 * Added check to server that unregistered connections cannot
5807 execute commands (unless it is specificly allowed).
5809 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Fixed screen refresh.
5813 * Fixed channel joining bug from client. On some circumstances
5814 client tried to join to a channel it had already joined.
5816 * Added public key verification process into client's protocol.c.
5817 The client now verifies the public key from user and saves
5818 it into ~./silc/serverkeys/ directory.
5820 Added into: clientutil.[ch]: silc_client_verify_server_key.
5822 * Changed SKE protocol's silc_ske_initiator_finish function
5823 to accept callback function that verifies the received public
5824 key. Removed old silc_ske_verify_public_key function.
5826 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5829 silc_pkcs_private_key[_data]_set.
5831 * Made the password and public authentication more cleaner in
5832 server's protocol.c.
5834 * Removed historic and obsolete protocol `channel_auth' from
5835 both client and server.
5837 * Removed wrong way of sending command status messages from
5838 server to client in server's command.c. The old way violated
5839 protocol specification.
5841 Changes to silccore/silccommand.[ch]: removed
5842 silc_command_encode_status_payload -> not needed anymore,
5843 changed silc_command_encode_payload_va to accept extra
5844 argument on variable argument list. The argument type must
5845 now be provided to the function. Also, added new function:
5846 silc_command_encode_reply_payload_va which is same as
5847 normal command_encode_payload_va except command status type
5848 is provided as extra argument.
5850 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Added ~./silc directory handling. The directory includes the
5853 public and private keys for the client.
5855 Added silc_client_check_silc_dir, silc_client_create_identifier
5856 and silc_client_load_keys.
5858 * Implemented SILC protocol compliant public key. Added public
5859 and private key saving to and loading from files.
5861 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5862 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5863 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5864 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5865 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5867 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5868 silc_pkcs_load_[public/private]_key.
5870 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * Added silc_server_get_route (route.[ch]) to get connection
5873 data for the fastest route for given ID.
5875 * Implemented INVITE command on client and server. The command
5876 were re-defined in the SILC Protocol Specification and the
5877 implementation now complies with the specification.
5879 * Implemented PING command on client and server.
5881 * Implemented NAMES command on client and server. The server side
5882 supports currently only normal server not router server yet.
5883 Some changes to NAMES definition in SILC protocol specification.
5885 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Implemented LEAVE command on client and server.
5889 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5890 again. This change was made to the protocol as well. Server
5891 should not violate the protocol specification anymore.
5893 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5896 was tested. SOCKS4 was not but should work anyway.
