3 * Added silc_log_set_debug_string function to set a regex
4 string to match for debug output. Only the function names,
5 or filenames matching the given debug string is actually
6 printed. This way it is possible to filter out those debug
7 strings that user is not interested in.
9 Fixed a bug in silc_string_regexify.
11 Affected files lib/silcutil/silclog.[ch], and
12 lib/silcutil/unix/silcunixutil.c.
14 * Changed the -d options in both server and Irssi SILC client
15 to take the debug string as argument. Affected files
16 silcd/silcd.c and irssi/src/silc/core/silc-core.c.

20 * Added silc_hash_babbleprint to create a Bubble Babble
21 Encoded fingerprint. The encoding is developed by Antti
22 Huima (draft-huima-babble-01.txt), and it creates human
23 readable strings out of binary data. Affected file
24 lib/silccrypt/silchash.[ch].
26 * Print the babble print now in addition of fingerprint as well
27 in Irssi SILC client. Affected files are
28 irssi/src/fe-common/silc/module-formats.[ch],
29 irssi/src/fe-common/silc/core/client_ops.c.
31 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
33 * Fixed a security problem found in SKE. The initiator's
34 public key too is now added to the HASH hash value creation
35 which is signed by the responder to create the SIGN value.
36 This will prevent anyone in the middle to lie to the responder
37 about the initiator's public key. If this is done now, the
38 man in the middle will get caught. Updated the protocol
41 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
43 * Better installation directory handling. Configure module
44 paths and other paths automatically to example_silc* files
45 in doc/. A patch by toma.
47 * Fixed compiler warning from MPI library, and from SILC RNG.
50 * Added SILC_SERVER_PID_FILE to define the pid file for server.
51 It can be configured with ./configure. A patch by toma.
53 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>

77 * Added silc_pkcs_public_key_compare to compare two
78 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
80 * Check that the client who set the founder mode on the
81 channel is the same client that is giving the founder
82 mode to itself. It is done by comparing the saved public
83 key (it is saved even in the authentication is passphrase).
84 Affected file silcd/command.c.
86 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
88 * Do not process packet for disconnected socket connection.
89 Affected file lib/silccore/silcpacket.c.
91 * Process the DISCONNECT packet through scheduler in the
92 client library. Affected file lib/silcclient/client.c.
94 * Fixed the silc_client_packet_parse to not to increase
95 the packet sequence number if the conn->sock and the
96 current socket connection is not same. This can happen
97 for example during key agreement when the conn includes
98 multiple socket connections (listeners). Affected file
99 lib/silcclient/client.c.
101 * The sender of the file transfer request now provides also
102 the pointer (listener) for the key exchange protocol. If
103 the listener cannot be created then it sends empty key
104 agreement and lets the receiver provide the listener.
106 Added `local_ip' and `local_port' arguments to the
107 silc_client_file_send. If they are provided they are used,
108 if not then it will attempt to find local IP address, if
109 not found or bind fails then the remote client will provide
112 Affected files are lib/silcclient/client_ftp.c and
113 lib/silcclient/silcapi.h.
115 * Extended the FILE SEND command to support defining the
116 local IP and port for key exchange listener. They are

121 * Defined to WHOIS command reply the sending of fingerprint
122 of the client's public key (if the proof of posession of the
123 corresponding private key is verified by the server).
124 Updated to the protocol specification.
126 * Added support of receiving the client's public key's
127 fingerprint in command reply in client library. Affected
128 file is lib/silcclient/command_reply.c, and
129 lib/silcclient/idlist.[ch].

184 client library. Affected file lib/silcclient/client_prvmsg.c.
186 * Do not actually remove the client directly from ID cache
187 during SERVER_SIGNOFF, but invalidate it. This way we
188 preserve the WHOWAS info for the client. Affected file
191 * Fixed SERVER_SIGNOFF notify handling in the server. The
192 server is now able to process incoming SERVER_SIGNOFF notify
193 for a server that it doesn't even know about. It will remove
194 the clients provided in the notify. Affected file
195 silcd/packet_receive.c.
197 * Check for partial packet in data queue after every packet that
198 was found from the queue. Return and wait for more data if
199 there is partial data in queue. Affected file is
200 lib/silccore/silcpacket.c.
202 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

217 irssi/src/fe-common/silc/module-formats.[ch].
219 * Wrote a help file for FILE command.
221 * Added silc_rng_global_get_byte_fast to get not-so-secure
222 random data as fast as possible. Random data is read from
223 /dev/urandom if available and from the SILC RNG if not
224 available. It is used in padding generation. Affected file
225 lib/silccrypt/silcrng.[ch].
227 * All packets in client library are now processed synchronously.
228 Optimized packet processing a lot. Affected file
229 lib/silcclient/client.c.
231 * All server connection packets are processing synchronously
232 now in server, to optimize packet processing. Affected file
235 * Include files are installed now only in Toolkit distribution
236 if make install is given. Affected files: all Makefile.am's.
238 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
240 * Assure that silc_client_notify_by_server_resolve does not
241 resolve the client information multiple times. If it cannot
242 be found by the first it cannot be found at all. Affected
243 file lib/silcclient/client_notify.c.
245 * Fixed WHOWAS command reply calling. Affected file
246 lib/silcclient/command_reply.c.
248 * Removed all references to silc_idlist_get_client from the
249 Irssi SILC client since that call is internal call used by
250 the library. The Irssi SILC client will use now client
251 retrieval functions found in silcapi.h.
253 * Fixed a bug in resolving nickname info before sending
254 private message. It used freed memory. Affected file
255 irssi/src/silc/core/silc-servers.c.
257 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

276 * Added silc_net_localip to return local host's IP address.
277 Affected file lib/silcutil/silcnet.[ch].
279 * If key exchange or rekey protocol is active for a connection
280 parse all packets syncronously since there might be packets
281 in packet queue that we are not able to process without first
282 processing packets before them. Affected file silcd/server,
283 lib/silcclient/client.c.
285 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
286 whether library should continue processing the packet.
287 Affected file lib/silccore/silcpacket.h.

333 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
334 is incomplete and is being resolved, it won't be resolved
337 Make sure also that USERS command reply does not resolve
338 twice information. Affected file is
339 lib/silcclient/command_reply.c.
341 Make sure that silc_client_get_clients_by_list does not
342 resolve twice same information.

370 * Redefined the SILC packet header to include the padding
371 length. Affected file lib/silccore/silcpacket.[ch].
373 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
374 length for maximum padding up to 128 bytes). Affected
375 file lib/silccore/silcpacket.h.
377 * Removed all backwards support for old 0.5.x MAC thingies.
378 The SILC packet header change makes it impossible to be
379 backwards compatible.
381 * Send the ENDING packet with timeout in the backup resuming
382 protocol. This is to assure that all routers has connected
383 to the primary router. Affected file silcd/server_backup.c.
385 * Changed the RNG to take the first IV from random data. It
386 used to take it from zero actually. Changed the RNG also
387 to use /dev/urandom during session. /dev/random is used
388 in initialization. Affected file lib/silccrypt/silcrng.[ch].
390 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
392 * Changed the SILC packet header to have the first two bytes
393 (the packet length) encrypted. Affected files aroung the
394 code tree, lib/silccore/silcpacket.[ch]. Removed the
395 SilcPacketCheckDecrypt callback. It is not needed anymore
396 since the silc_packet_receive_process will determine now
397 whether the packet is normal or special.
399 * Implemented the unidirectional MAC keys. Affected files
400 lib/silcske/silcske.c, silcd/protocol.c and
401 lib/silcclient/protocol.c.

408 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
410 * Allow backup router to announce servers. All servers
411 announced by backup router are added to the global list
412 automatically. Update hte server's socket to our primary
413 router also when backup router announces a server.
414 Affected file silcd/packet_receive.c.
416 * Do not update the client->router in the function
417 silc_server_udpate_clients_by_server if the client is on
418 global list. We might fail to find any specific server
419 for locally connected clients and local cell clients. They
420 should still use the `from' and not `to' as client->router.
421 This fixes backup router resuming protocol. Affected file
424 * Decrease channel statistics count only if the channel
425 deletion worked. Affected files are silcd/server.c and
428 * Added silc_server_update_servers_by_server to update origin
429 of all server entries. Used during backup router protocol.
430 Affected files silcd/server_util.[ch], silcd/server.c. and

441 to the sender. Affected file silcd/packet_receive.c.
443 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Made better checks that the channel message is not sent
446 to the router it came from. Affected file is
447 silcd/packet_send.c. Fixed memory leak too.
449 * Announce informations for incoming router connection, but
450 only after checking if it is replaced by backup router.
451 Affected file silcd/packet_receive.c.
453 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

456 router environment. Affected file silcd/server_backup.c.
458 * Route packet only to one router in the function
459 silc_server_packet_send_to_channel. Affected file is
462 * Fixed silc_server_send_notify_dest to set the broadcast
463 flag. Fixed the silc_server_send_notify_topic to actually
464 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
465 Affected file silcd/packet_send.c.
467 * Changed the SFTP Filesystem interface. Changed the
468 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
469 the filesystem operation function. The SilcSFTPFilesystem
470 is now a context that is allocated by all filesystem allocation
471 functions and it already includes the operations structure
472 and filesystem specific context. It is given as argument
473 now to the silc_sftp_server_start. This made the interface
474 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
475 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
477 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
479 * Changed the backup router adding and getting interfaces
480 in the server. The router that will be replaced by the
481 specified backup router is now sent as argument. Affected
482 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
485 * Added silc_net_addr2bin_ne to return the binary form of
486 the IP address in network byte order. Affected files
487 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].

551 lib/silcsftp/tests directory.
553 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
555 * Implemented memory filesystem (virtual filesystem) for
556 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
559 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Implemented the SFTP (SSH File Transfer Protocol) to the
562 lib/silcsftp. It includes SFTP client and SFTP server
565 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
567 * Moved lib/silccore/silcprotocol.[ch] to the
568 lib/silcutil library.
570 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
571 take variable argument list pointer as argument. Affected
572 file lib/silcutil/silcbuffmt.[ch].
574 * Added silc_buffer_set function that is used to set data
575 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
576 Affected file lib/silcutil/silcbuffer.h.
578 * Changed various routines in the core library to use the new
579 silc_buffer_set instead of allocating new buffer only for
582 * Added 64-bit value formatting and unformatting support to the
583 silc_buffer_[un]format routines. Affected file is
584 lib/silcutil/silcbuffmt.[ch].
586 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
587 to includes/bitmove.h.
589 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
591 * Fixed channel user mode saving in client library. Affected
592 file lib/silcclient/command[_reply].c.
594 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
596 * Defined the file transfer to the SILC Protocol. Added
597 new packet type SILC_PACKET_FTP and defined File Transfer
598 Payload. The mandatory file transfer protocol is SFTP
599 (SSH File Transfer Protocol). Affected file in addition
600 of the internet draft is lib/silccore/silcpacket.h.
602 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
603 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
604 is used as part of backup router protocol when the primary
605 router of the cell is back online and wishes to resume
606 the position as primary router.
608 * Redefined the MAC generation keys in the protocol. The
609 same key is not used anymore in both direction. Both
610 direction will now use different keys for sending and
611 receiving. This fixes a potential security flaw. This
612 change causes incompatibilities in the protocol.
614 * Redefined also the MAC computation from the packet.
615 An packet sequence number is now added to the MAC
616 computation. This prevents possible replay attacks against
617 the protocol. This change too causes incompatibilities
620 Added `sequence' field to the SilcPacketContext to hold
621 the current sequence number for the packet.
623 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
625 * Added `created' field to the SilcIDListData in the file
626 silcd/idlist.h to indicate the time when the entry was
629 * Added `created' field to the SilcChannelEntry too. Affected
632 * Added `creation_time' aguments to all the announcement functions
633 in the server. If it is provided then only the entries that
634 was created after the provided time frame are actually
635 announced. Affected file silcd/server.[ch].
637 * The protocol says that the Channel ID's IP address must be
638 based on the router's IP address. Added check for this in
639 the silc_server_new_channel when processing incoming New Channel
640 Payload. Affected file silcd/packet_receive.c.
642 * Print out the correct version with --version in SILC client.
643 Affected file irssi/src/silc/core/silc-core.c.
645 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
647 * Fixed WHOWAS command to check for completnes of the client
648 entry always, not just when the command is coming from client.
649 Affected file silcd/command.c.
651 * Added new function silc_server_packet_queue_purge to purge the
652 outgoing data queue to the network. After the function returns
653 it is guaranteed that the outgoing packet queue is empty.
654 Affected file silcd/packet_send.[ch].
656 * Purge the outgoing packet queue in the rekey protocol's final
657 callback to assure that all rekey packets go to the network
658 before quitting the protocol. Affected file silcd/server.c.
660 * Added silc_client_packet_queue_parse as similar function as
661 in server to the client library. The affected file is
662 lib/silcclient/client.c.
664 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
666 * Splitted silcd/server.c and created silcd/server_util.[ch]
667 for utility functions.
669 * Added new socket flag SILC_SF_DISABLED to indicate that the
670 connection is open but nothing can be sent to or received from
671 the connection. Affected file lib/silcutil/silsockconn.[ch].
672 The checking for disabled socket is checked in the low level
673 silc_socket_write and silc_socket_read functions.
675 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
677 * Allow only nicknames and channel names that fits into the
678 7-bit unsigned char ASCII set. Affected file silcd/command.c.
680 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
682 * When processing JOIN command reply in server check that if
683 the channel exists in our global list we'll move it the local
684 list. Affected file silcd/command_reply.c.
686 * Fixed the check whether client is joined on the channel already
687 in JOIN command. Affected file lib/silcclient/command.c.
689 * Fixed the JOIN command reply to check whether the channel
690 already exists. Affected file lib/silcclient/command_reply.c.
692 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
694 * Added silc_ske_status_string to map the SKE error numbers
695 to readable strings. The affected files are
696 lib/silcske/silcske[_status].[ch].
698 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
700 * Do not show the private channels on the WHOIS channel list
701 as it is not allowed by the protocol. The affected file is
704 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
706 * Assure that the packet length digged from the actual packet
707 is something sensible in the silc_packet_decrypt_rest_special
708 in lib/silccrypt/silcpacket.c.
710 * Free and NULL the allocated pointer in silc_hmac_alloc if
711 the HMAC allocation fails. The affected file is
712 lib/silccrypt/silchmac.c.
714 * Print the selected security properties to the log files in
715 the server. Affected file silcd/protocol.c.
717 * Add SKE's reference counter even if calling the completion
718 callback manually. Otherwise it goes negative, although it
719 does not cause any problems. The affected file is
720 lib/silcske/silcske.c.
722 * Remove the client entry with short timeout after giving the
723 KILL command. Affected file lib/silcclient/command.c.
725 * Fixed to send error reply in WHOIS and IDENTIFY commands in
726 case all found clients are already disconnected (WHOWAS would
727 found them) in the server. Affected file silcd/command.c.
729 * Update the last_receive (time of last data received) to be
730 updated only when received private or channel message so that
731 the idle time showed in WHOIS makes more sense.
733 * Added boolean field `valid' in to the SilcClientEntry in the
734 client library to indicate whether the entry is valid or not.
735 This fixes the nickname change bug on channel when changing
736 the nickname to be same than the old (like nick to Nick) the
737 nickname formatter doesn't set the new nick anymore to Nick@host.
738 Affected file lib/silcclient/idlist.[ch].
740 * Now actually fixed the nickname changing on disconnection.
741 Added new function silc_change_nick to the Irssi SILC Client.
742 Affected file irssi/src/silc/core/client_ops.c,
743 irssi/src/silc/core/silc-nicklist.[ch].
745 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
747 * Check that the public key exists in the GETKEY command before
748 trying to encode it. Affected file silcd/command.c.
750 * Print some notifications on received public keys with GETKEY
751 command in the Irssi SILC Client. Affected files are
752 irssi/src/fe-common/silc/module-formats.[ch],
753 irssi/src/silc/core/client_ops.c.
755 * Use IDENTIFY command to resolve the server information in the
756 GETKEY command instead of INFO command. Affected file
757 lib/silcclient/command.c.
759 * All command reply functions in the client library now calls
760 the pending command reply callbacks even if an error has
761 occurred. The server has done this a long time and now it was
762 time to move the client library to this as well. Now all
763 errors can be delivered back to the pending command reply
764 callbacks if necessary. Affected files are
765 lib/silcclient/command[_reply].[ch].
767 * Change the nickname on disconnection back to the username
768 because in reconnect the server will enforce it to it anyway.
769 Affected file irssi/src/silc/core/silc-servers.c.
771 * Fixed a config file parsing bug in the Irssi SILC client.
772 Affected file irssi/src/silc/core/clientconfig.c.
774 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
776 * When printing the channel mode on JOIN, verify that the
777 channel key and channel's HMAC are valid. Affected file
778 irssi/src/silc/core/client_ops.c.
780 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
783 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
784 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
786 * Removed channel key rekey task deleting from the function
787 silc_server_save_channel_key. Affected file silcd/server.c.
788 Added explicit timeout task context instead that is used to
789 delete the task if we are registering a new task before the
790 new task has elapsed.
792 * When channel key rekey occurs the client library now saves
793 the old channel key for a short period of time (10 seconds) and
794 is able to use it in case some is still sending channel
795 messages encrypted with the old key after the rekey. Affected
796 file lib/silcclient/[idlist.h|client_channel.c].
798 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
800 * Added check to the silc_server_new_id_real to not accept
801 new ID if it is the sender's own ID. Affected file is
802 silcd/packet_receive.c.
804 * Assure that we do not announce ourself or the one we've
805 sending our announcements when we're router and are announcing
806 servers to our primary router. Affected file silcd/server.c.
808 * Fixed silc_server_command_identify_check_client to assemble
809 correct WHOIS packet. It send corrupted WHOIS packet and
810 caused problem with router to router connections. Affected
811 file silcd/command.c.
813 Fixed also silc_server_command_whois_check the same way
814 as for the IDENTIFY command.
816 * Added new SilcIDListStatus to the server in the SilcIDListData
817 structure. The status now includes the current status of
818 the entry (like registered, resolved etc.). Affected file
819 silcd/idlist.[ch]. Defined a bunch of different status types
820 as well. This replaced the old boolean registered field as well.
822 Added resolve_cmd_ident field to the SilcClientEntry structure
823 too so that if the entry is for example being resolved so
824 another command may attach to the same pending command reply
825 without requiring to resolve the same entry again. This concept
826 should optimize the WHOIS and the IDENTIFY resolving under
827 heavy load by taking away unnecessary resolving for entries
828 that are being resolved already.
830 Added support for adding multiple pending commands for one
831 command idenfier. Affected file silcd/command[_reply].[ch].
833 * Fixed WHOIS and IDENTIFY save to remove the cache entry
834 before deleting the data. Otherwise the hash table will have
835 freed data in comparison functions. Affected file is
836 silcd/command_reply.c.
838 * Fixed silc_idlist_replace_client_id to add the new entry to
839 the cache with NULL nickname. Otherwise there will be invalid
840 memory as the nickname after the nickname is freed. Affected
841 file silcd/packet_receive.c.
843 * Fixed the silc_idlist_get_clients_by_hash. The entries was
844 saved into wrong slots because the previous number of entries
845 was not taken into account. Affected file silcd/idlist.c.
846 Fixed same thing in silc_idlist_get_clients_by_nickname too.
848 * If we are router and we receive JOIN notify to a channel that
849 does not have any users then notified client is marked as the
850 channel founder, as it is it. The affected file is
851 silcd/packet_receive.c
853 * Added to the extended hash table API's table_del_*ext functions
854 the destructor as argument too, so that the caller can decide
855 which destructor to use or whether to use destructor at all.
856 Affected file lib/silcutil/silchashtable.[ch].
858 * Fixed ID Cache purging. It actually deleted the entries from
859 the hash table after the data was freed. The hash table ended
860 up comparing freed memory. The affected file is
861 lib/silccore/silcidcache.c.
863 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Fixed Irssi SILC client's KILL command's HELP syntax.
867 * The USERS command now resolves the detailed user information
868 if the userinfo field is missing. Affected file is
869 lib/silcclient/command_reply.c.
871 * Do not print error in silc_file_read if the read file does
872 not exist. Just silently return NULL. Affected file is
873 lib/silcutil/silcutil.c.
875 * Fixed the silc_log_output to not wine about NULL filename
876 and to not create some bogus " " filename. Affected file is
877 lib/silcutil/silclog.c.
879 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
881 * Fixed various printing bugs on the user interface in the
882 Irssi SILC Client. Minor changes that were forgotten from
885 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
887 * Fixed the configure.in.pre and the compilation and distribution
888 environment to support the new autoconf 2.52. That version is
889 now required to compile the CVS trunk.
891 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
893 * Renamed function silc_parse_nickname to silc_parse_userfqdn
894 to generally parse user@fqdn format strings. Affected file
895 lib/silcutil/silcutil.c.
897 * Added nickname_format and nickname_force_format fields to the
898 SilcClientParams structure. The first one defines the format
899 for the nicknames that the library will enforce if the receives
900 multiple same nicknames. The second one is boolean value and
901 can be used to force the library to always enforce the format
902 to the nicknames regardles whether there are multiple nicknames
903 or not. This configurable formatting was employed to flexibly
904 support accessing multiple nicknames from the user interface.
905 The userinterface can now set the nicknames to what ever format
906 they prefer. Affected file lib/silcclient/silcapi.h.
908 Added function silc_client_nickname_format to the file
909 lib/silcclient/idlist.c. It performs the nickname formatting.
911 Added new field `hostname´ to the SilcClientEntry context.
912 It holds the hostname of the client. Affected file is
913 lib/silcclient/idlist.h.
915 * Irssi SILC Client sets the nicknames in nick@hostn format.
916 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
917 irssi/src/silc/core/silc-core.c.
919 The WHOIS printing now also shows both the real nickname and
920 the formatted nickname so that user knows how to access the
921 user if there are multiple same nicknames cached. Affected
922 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
923 printing formatting too to take the hostname now as a separate
924 argument. The Affected file is
925 irssi/src/fe-common/silc/modules-formats.[ch].
927 * Changed the silc_client_get_clients_local to accept the formatted
928 nickname as argument. It accepts the real nickname too but the
929 formatted nickname can be used to find the true entry from
930 multiple entries. Affected file lib/silcclient/silcapi.h and
931 lib/silcclient/idlist.c.
933 * Added nickname_format_parse field to the SilcClientParams.
934 It is a callback function provided by the application to parse
935 the nickname out of the formatted nickname string. The library
936 calls it to get the nickname from the formatted string. Since
937 the application generally knows better the format of the nickname
938 string it parses it instead of the library, even though library
939 encodes the formatted string. If the callback function is not
940 provided then the library will use the string as is. The
941 affected file is lib/silcclient/silcapi.h.
943 * All the nickname strings passed to the client library in
944 commands are now expected to be formatted nickname strings.
945 If the command does not support the formatted nickname string
946 it will assume that the sent string is the actual nickname.
947 Affected file lib/silcclient/command.c.
949 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
951 * Added public key authentication support to OPER and SILCOPER
952 commands in the client library. Affected file is
953 lib/silcclient/command.c.
955 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
957 * Changed the get_auth_methdod client operation to be asynchronous.
958 It can be async if the application resolves the authentication
959 method from the server during the negotiation. Added new
960 SilcGetAuthMeth completion callback that the application will
961 call after resolving the authentication method.
963 Added function silc_client_request_authentication_method that
964 the application can use to resolve the authentication method
965 from the server. Added also SilcConnectionAuthRequest callback
966 that the library will call after the server has replied. The
967 application can call this function if it does not know the
968 current authentication method.
970 Affected files are lib/silcclient/client.c and
971 lib/silcclient/silcapi.h.
973 * The Irssi SILC client now automatically resolves the authentication
974 method incase any configuration information is not present (and
975 currently there never is). The affected file is
976 irssi/src/silc/core/client_ops.c.
978 * Fixed public key authentication from the client library.
979 Affected file lib/silcclient/protocol.c. Changed also the
980 protocol specification about the public key authentication in
981 the connection authentication protocol. The actual data to be
982 signed is now computed with a hash function before signing.
984 * Fixed the public key authentication from the server as well.
985 Affected file silcd/protocol.c.
987 * Removed the mlock()'s from the memory allocation routines.
988 Affected file lib/silcutil/silcmemory.c. The ./configure does
989 not check anymore for the mlock(). Affected file is
992 * Fixed USERS command in server to allow the execution of the
993 command for private and secret channels if the client sending
994 the command is on the channel. Affected file silcd/command.c.
996 * Fixed silc_client_get_clients_local to return the clients
997 count correctly. It could return wrong value. Affected file
998 lib/silcclient/idlist.c.
1000 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1002 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
1003 types. The assembler optimizations seemed not to like 64-bit
1004 data types. The assmebler optimizations thus are now enabled
1005 also for BSD systems as opposed to only enable them for Linux.
1007 * Do not check for threads at all on BSD systems. Affected
1008 file configure.in.pre.
1010 * Removed -n and -h options from the Irssi SILC Client since
1011 they are not used in silc.
1013 * Fixed the prime generation to assure that the first digit
1014 of the generated random number is not zero since our conversion
1015 routines does not like number strings that starts with zero
1016 digit. If zero digit is seen the random number is regenerated.
1017 This caused some corrupted RSA keys when the zero first digit
1018 was met. Affected file lib/silcmath/silcprimegen.c.
1020 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1022 * Fixed WIN32 configuration in the ./configure script.
1023 Fixed to include xti.h on environments that has it.
1024 Patches by Carsten Ilchmann and andrew.
1026 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Changed the silc_id_create_client_id to be collision
1029 resistant. It is now assured that there cannot be created
1030 two same client ID's. I suspect that some weird bugs in
1031 the server were actually caused by duplicate Client IDs.
1032 Affected file silcd/serverid.[ch]. A router receiving
1033 new ID now also assures and informs the sending server
1034 if the ID caused collision.
1036 * Changed the silc_id_create_channel_id to also assure that
1037 there are no collisions.
1039 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1041 * Statement about ignoring the Mutual Authentication flag when
1042 performing rekey with PFS was a bit misleading. It is ignored
1043 if it was set in the initial negotiation, it cannot be even
1044 set in the rekey. Fixed in the ke-auth draft. Started the
1045 new versions of the protocol drafts in the doc/.
1047 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1049 * Fixed a bug in silc_client_command_identify_save when saving
1050 new channel information. The channel name was no duplicated
1051 and caused crash on exit. Affected file is
1052 lib/silcclient/command_reply.c.
1054 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Fixed the getkey command handling in the server. Send just
1057 empty OK reply to the sender if the key could not be fetched
1058 (but everything else was ok, like the key just was not available).
1059 Changed the public key parameter to optional in the protocol
1060 specs so that empty OK reply can be sent. Affected file
1063 Added a message to Irssi SILC client to tell to user if the
1064 server did not return a public key.
1066 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1068 * Fixed a channel key regeneration bug. It registered new
1069 timeout tasks exponentially until all system resources were
1070 used. Affected file silcd/server.c.
1072 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1074 * Added the SILC Document generator to the scripts/silcdoc.
1075 It can be used to generate the Toolkit Reference Manual out
1076 of the source tree. Internally it will also use the RoboDoc
1077 generator now imported in util/robodoc.
1079 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1081 * Added couple of return's in rekey protocol if error orccurred
1082 during the protocol. The execution must be terminated.
1083 Affected file silcd/protocol.c. Also, terminate the protocol
1084 always with timeout.
1086 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1088 * The client's Client ID was created initally from the wrong
1089 nickname (it could have been in format nick@host) in the
1090 silc_server_new_client. Affected file silcd/packet_receive.c
1092 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1094 * Added some SILC_LOG_ERROR's to various error conditions
1095 if client could not be added to ID cache. Affected files
1096 silcd/packet_receive.c and silcd/server.c.
1098 * When client's sock->user_data is freed, NULL also the
1099 client->router and client->connection pointers. Added check
1100 for these pointers being NULL to various places around the
1101 code. Affected file silcd/server.c.
1103 * Added client->data.registered == TRUE checks to various
1104 places around the code to assure that unregistered client's
1105 are not handled when it is not allowed. Affected file
1108 * Added `bool registered' fields to all
1109 silc_idlist_[server|client]_get_* routines to indicate whether
1110 the fetched client needs to be registered or not. Affected
1111 file silcd/idlist.[ch].
1113 * Add your own entry as registered to the ID cache in the
1114 server. Affected file server.c.
1116 * Fixed a bug in silc_server_new_server. The SilcServer was
1117 set as the new server's context instead of SilcServerEntry.
1118 This naturally caused some weird bugs.
1120 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1122 * Do not delete the channel rekey task when adding it
1123 for in silc_server_create_channel_key.
1125 * Changed the silc_server_create_channel_key to return
1126 TRUE or FALSE to indicate the success of the channel key
1129 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1131 * Fixed MSVC++ project files and added missing files to

1137 does not have it defined. Affected files are
1138 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1140 * Fixed buffer overflow from Irssi SILC Client. Affected
1141 file irssi/src/fe-common/core/themes.c.
1143 * Fixed double free in client library in the file
1144 lib/silcclient/client.c when disconnecting from server.
1146 * Applied double free patch from cras to Irssi SILC client.
1147 Affected files irssi/src/core/[modules/expandos].c
1149 * Fixed the disconnection handling to Irssi SILC Client.
1150 The application must call silc_client_close_connection
1151 in ops->connect client operation in case of failure of
1152 the connection. Affected file is
1153 irssi/src/silc/core/client_ops.c.
1155 * Do not set sock->protocol to NULL in the function
1156 silc_client_close_connection after executing the protocol's
1157 final callback since the sock might not be valid anymore.
1158 Affected file lib/silcclient/client.c.
1160 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Do not enable SILC_THREADS if the linking with libpthread
1163 did not happen. Affected file configure.in.pre.
1165 * Added notion to protocol specification that server must
1166 verify the sent authentication payload with CMODE when
1167 setting the channel founder key. Implemented it to the
1168 server. Affected file silcd/command.c.
1170 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1172 * Added _EXTRA_DIST SILC distribution variable to the
1173 distributions file. It is used to conditionally add extra
1174 files or directories to the specific distribution. Affected
1175 files ./prepare, Makefile.am.pre and distributions.
1177 Removed the `_' from the start of the distribution names.
1180 * Added README.WIN32 for instructions to compile the Toolkit
1183 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed a double free in disconnection in the server. Affected
1186 file is silcd/server.c.
1188 * Fixed the lib/silcske/groups.c to work now also with GMP
1189 MP library. The string conversion did not work when using
1190 specific base and the base is indicated in the string as well.
1192 * Created win32/ directory which now includes MSVC++ specific
1193 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1194 It will appear only in the toolkit distribution
1196 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1198 * Changed the key material distribution function in case when
1199 the hash output is too short. The data is now concatenated
1200 a bit differently than it used to. Made the change to the
1201 SKE protocol specification.
1203 * Added better GMP detection to configure.in.pre. A patch
1206 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1208 * Fixed a minor bug in SKE that might cause some problem on
1209 some platforms. Affected file lib/silcske/silcske.c.
1211 * Added the cookie checking for initiator in the SKE. It checks
1212 that the responder returns the sent cookie unmodified. The
1213 affected file is lib/silcske/silcske.c. Added new SKE
1214 error type INVALID_COOKIE that can be sent during the
1215 negotiation. Fixed some memory leaks as well.
1217 * Added the "invalid cookie" error message to Irssi SILC client's
1220 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1222 * Added `task_max' field to the SilcClientParams to indicate
1223 the maximum tasks the scheduler can handle. If set to zero,
1224 default values are used. Affected file lib/silcclient/silcapi.h.
1226 * Fixed memory leaks in silc_client_close_connection. Affected
1227 file lib/silcclient/client.c.
1229 * Added silc_client_del_client_entry to client library to free
1230 all memory of given client entry. Affected file is
1231 lib/silcclient/idlist.[ch].
1233 * Added new functions silc_client_del_channel and
1234 silc_client_del_server to delete channel and server entries.
1235 Affected file lib/silcclient/[silcapi.h/idlist.c].
1237 * Removed silc_client_del_client_by_id from silcapi.h.
1239 * Fixed the INFO command to return the server's own info
1240 correctly when querying by Server ID. Affected file is
1243 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1245 * Removed the non-blocking settings in WIN32 code in the
1246 silc_sock_[read/write] and added SleepEx instead. Affected
1247 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1248 of input data is now checked with FIONREAD and ioctlsocket.
1250 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * Call silc_schedule_task_del_by_context in the
1253 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1254 Affected file lib/silccore/silcprotocol.c.
1256 * Call silc_protocol_cancel for active protocols in the
1257 silc_server_close_connection if the funtion
1258 silc_server_free_sock_user_data has not been called.
1259 Affected file silcd/server.c.
1261 * Generic tasks cannot be deleted using the del_by_fd
1262 task deleting function since generic tasks does not match
1263 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1265 * Added a notion to SILCOPER help file that the SILCOPER works
1266 only on router server, not on normal server.
1268 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1270 * Added for WIN32 support for the new scheduler as well.
1271 Affected file lib/silcutil/win32/silcwin32schedule.c.
1273 * Fixed the SHA1 implementation to work on various platforms.
1275 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1278 API. It is part of the scheduler now. Everything else is
1279 as previously but some functions has changed their names.
1280 Checkout the lib/silcutil/silcschedule.h for the interface.
1281 Updated all applications to use the new interface. Affected
1282 files are lib/silcutil/silcschedule.[ch].
1284 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Found a bug in the SKE implementation. The HASH value,
1287 specified by the protocol, was not computed correctly. The
1288 public key of the responder was not added to the computation
1289 even though it is mandatory. Affected file lib/silcske/silcske.c.
1290 This unfortunately causes incompatibilities with older
1291 clients and servers.
1293 * Added WIN32 specific network init and uninit functions:
1294 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1295 the Winsock2. Affected file lib/silcutil/silcnet.h and
1296 lib/silcutil/win32/silcwin32net.c.
1298 * Set the socket always to nonblocking mode on WIN32 after
1299 reading data or writing data. Affected file is
1300 lib/silcutil/win32/silcwin32sockconn.c.
1302 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1304 * Fixed various compilation problems under WIN32. Affected
1305 files lib/silcutil/win32/silcwin32thread.c and
1306 lib/silcutil/win32/silcwin32schedule.c.
1308 * Removed all _internal.h #includes from public header
1309 files. Internal headers must never be included from
1312 Removed also the lib/silcske/payload_internal.h file.
1314 * All include files that may be needed (public and some others
1315 included by the public headers) by application developers are
1316 now copied to the ./includes directory. It does not copy any
1317 internal headers. Affected file Makefile.defines.pre and all
1318 Makefile.am's under lib/ and subdirs.
1320 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1322 * Do not change the ~/.silc directory's permissions automatically.
1323 Affected file irssi/src/silc/core/clientutil.c.
1325 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1327 * Do not cancel the protocol in silc_server_close_connection
1328 it might cause recursion. Now cancelled in the function
1329 silc_server_free_sock_user_data. Affected file silcd/server.c.
1331 * Fixed the silc_server_remove_clients_by_server to regenerate
1332 the channel keys correctly finally. Added also new function
1333 silc_server_remove_clients_channels to actually do it.
1334 Affected file silcd/server.c.
1336 * Fixed the silc_server_new_channel to not crash by giving
1337 wrong router to the new channel. Affected file is
1338 silcd/packet_receive.c.
1340 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1342 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1343 which is given as argument to the silc_client_alloc now.
1344 It can be used to configure the client and set various parameters
1345 that affect the function of the client.
1347 * The USERS command in server did not check whether the channel
1348 is private or secret. Affected file silcd/command.c.
1350 * Added new argument to the USERS command in protocol specification.
1351 The USERS command now can take the channel name as argument
1352 as well. Added support for this in client and server and
1353 updated the protocol specs.
1355 * Completed the GETKEY command in client. It can be now used
1356 to fetch also servers public key not only some clients.
1357 Affected files lib/silcclient/command[_reply].c.
1359 * Added silc_client_get_server to return server entry by the
1360 server name. Affected files lib/silcclient/silcapi.h and
1363 * Redefined the IDENTIFY command in protocol specification to be
1364 more generic. It now can be used to query information about
1365 any entity in the SILC Network, including clients, servers and
1366 channels. The query may be based either the entity's name
1367 or the ID. Added support for this in both client and server.
1369 Affected files silcd/command.c and lib/silcclient/command.c
1370 and command_reply.c.
1372 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1373 the _from_client and _from_server functions. Affected file
1376 * Added silc_client_get_channel_by_id_resolve to the file
1377 lib/silcclient/silcapi.h to resolve channel information by
1378 its ID. Added also silc_client_get_channel_by_id that
1379 does not resolve it from the server.
1381 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * Added SilcServerEntry context into the client library
1384 to represent one server. The INFO command now allocates
1385 these to save the resolved server info. For now on the
1386 client library will also keep information about servers,
1387 connected and resolved with INFO.
1389 The INFO command now allocates the SilcServerEntry context
1390 and saves the server info there. The COMMAND_REPLY in
1391 the INFO now returns the parameters to application in
1392 same order as defined in the protocol specification.
1394 The entries are cached in the client->server_cache.
1396 * The INFO command is now issued after received the Client ID
1397 from the server. Affected file lib/silcclient/client.c.
1399 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1400 to the application as the mode changer might be server.
1401 It is guaranteed that NULL is not returned anymore to the
1402 application. Affected file lib/silcclient/client_notify.c.
1404 The ID Type is now also passed to the application so that
1405 it can check whether the returned entry is SilcClientEntry
1408 Added new function silc_client_get_server_by_id to return
1409 the server entry by ID. Affected files are the
1410 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1412 * Do not create the channel in the Irssi SILC Client when issuing
1413 the JOIN command but when received the sucessful JOIN command
1414 reply. Otherwise the channel might get created even though we
1415 could not join it. The Affected file is
1416 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1418 * Fixed a channel joining bug in router. The router must also
1419 check the channel modes, invite and ban lists etc. when serving
1420 the JOIN command sent by normal server. Affected file is
1421 silcd/command.c. The router now resolves the client's
1422 information from the server who sent the JOIN command if it
1423 does not know it, and processes the JOIN command only after
1426 * Changed the SilcCommandCb to take new argument; void *context2.
1427 Affected file lib/silccore/silccommand.h
1429 The second argument in the command callbacks in the server now
1430 includes the SilcServerCommandReplyContext if the command was
1431 called as pending command callback from the command reply.
1432 Otherwise it is NULL. When called as pending the status of the
1433 command reply will be checked and if it was erronous the
1434 error will be sent to the original sender of the command.
1435 This way the client always receives the error messages even
1436 though the server was actually the one who received the error
1437 when it resent the command to router, for example. Affected
1438 files silcd/command[_reply].[ch].
1440 * Fixed sending WHOWAS command's error message to client if
1441 the requested client could not be found. It was missing.
1444 * Changed the CMODE and CUMODE commands reply arguments in the
1445 protocol specification. The Channel ID is now sent in both
1446 of the commands to identify the channel. Implemented this
1447 new feature to the client and server. Affected files
1448 lib/silcclient/command_reply.c and silcd/command.c.
1450 * Made better checks for invite and ban lists in the JOIN
1451 command in server. Affected file silcd/command.c.
1453 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1455 * The server now performs the incoming host IP/DNS lookup
1456 using the silc_socket_host_lookup and thus does not block
1457 the server anymore. Affected file silcd/server.c.
1459 * Completed the multi-thread support for SILC Scheduler in
1460 the lib/silcutil/silcschedule.c.
1462 * Fixed the configure.in.pre to detect the pthread correctly
1465 * Fixed a deadlock in silc_task_queue_wakeup in the file
1466 lib/silcutil/silctask.c.
1468 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1470 * Added new function silc_schedule_wakeup that is used in
1471 multi-threaded environment to wakeup the main thread's
1472 schduler. It needs to be used when a thread adds a new task
1473 or removes a task from task queues. After waking up, the
1474 scheduler will detect the task queue changes. If threads
1475 support is not compiled in this function has no effect.
1476 Implemented the wakeup mechanism to both Unix and WIN32
1477 systems. Affected files are lib/silcutil/silcschedule.[ch],
1478 lib/silcutil/unix/silcunixschedule.c and the
1479 lib/silcutil/win32/silcwin32schedule.c.
1481 * Added new function silc_task_queue_wakeup to wakeup the
1482 scheduler by the specified task queue. Affected file
1483 lib/silcutil/silctask.[ch].
1485 * The silc_socket_host_lookup_start now wakes up the scheduler
1486 after adding the timeout task. Affected file is
1487 lib/silcutil/silcsockconn.c.
1489 * The silc_socket_host_lookup is synchronous now if the threads
1490 support is not compiled in. However, the callback is still
1491 called asyncronously through the scheduler, anyway. Affected
1492 file lib/silcutil/silcsockconn.c.
1494 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1496 * Added new function silc_socket_host_lookup to perform
1497 asynchronous IP and FQDN lookups for the socket connection.
1498 Affected files lib/silcutil/silcsockconn.[ch].
1500 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1502 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1503 that may or may not compile the mutex support in.
1505 Changed the silc_mutex_alloc interface. It allocates the
1506 mutex now to the sent pointer and returns TRUE or FALSE.
1508 Affected file lib/silcutil/silcmutex.h.
1510 * Wrote the SILC Task Queue interface to support multi-threads.
1511 Affected file lib/silcutil/silctask.[ch].
1513 * Wrote the SILC Scheduler to support multi-threads. Affected
1514 file lib/silcutil/silcschedule.c.
1516 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1518 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1519 in lib/silcutil/win32/.
1521 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1523 * Defined SILC Mutex API and SILC Thread API and implemented
1524 them for Unix. Affected files are
1525 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1526 lib/silcutil/unix/silcunixmutex.c and
1527 lib/silcutil/unix/silcunixthread.c.
1529 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Fixed the silc_server_remove_clients_by_server's channel
1532 key re-generation. The hash table handling was incorrect
1533 and would not work with many channels. Affected file is
1536 * Fixed some memory leaks around the server code.
1538 * Rewrote the silc_server_get_users_on_channel to support IPv6
1539 based Client ID's. Affected file silcd/server.c.
1541 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1542 specification. However, a separate document must be written
1543 to define the detailed signing procedure and the payload
1544 associated with the flag. Defined the flag to the
1545 lib/silccore/silcchannel.h as well.
1547 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1549 * Changed the dynamic tables to static size tables in the
1550 lib/silccrypt/silchmac.c.
1552 * Removed GCC dependencies from the code. A patch by cras.
1554 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Do not show the error "Error receiving packet bla bla"
1557 in server if it really was not an error (-2 means that reading
1558 is pending). Affected file silcd/server.c.
1560 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Fixed a possible crash in silc_server_remove_clients_by_server
1563 in silcd/server.c. Fixed there also some memory leaks.
1565 * Fixed the silc_idlist_replace_client_id. It could replace
1566 wrong key in the hash table. Affected file silcd/idlist.c.
1568 * Do not check whether there are global users on the channel
1569 if the channel->global_users is FALSE. Affected functions
1570 silc_server_remove_from_one_channel and
1571 silc_server_remove_from_channels in silcd/server.c. Also,
1572 do not check if the removed client is local as we can be
1573 sure that global client was not removed from the channel
1574 and checking for global users is not needed.
1576 * The silc_server_remove_clients_by_server now re-generates
1577 the channel keys correctly for those channels that had
1578 clients removed from them. Affected file silcd/server.c.
1580 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Found the reason of random crashes in the server. We weren't
1583 ignoring the SIGPIPE signal (which can be sent in write())
1584 and it crashed the server. Affected file silcd/silcd.c.
1586 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Assure that sock->user_data is not NULL in the function
1589 silc_server_packet_send in silcd/packet_send.c.
1591 * Disconnect the remote connection if it could not be added
1592 to any ID lists in the server. The affected file is
1595 * Check in silc_server_packet_send[_real/dest] that the
1596 socket is not disconnecting and ignore the data if it is.
1597 Affected file silcd/packet_send.c.
1599 * Define inline to __inline on native WIN32 compilation.
1600 Affected file includes/silcwin32.h.
1602 * Added some explicit type casts for inline code since MSVC
1603 require them. Affected files lib/silcutil/silcbuffer.h,
1604 lib/trq/silcdlist.h and lib/trq/silclist.h.
1606 * Print warning in log files from now on if the packet
1607 decryption fails. Affected file silcd/server.c.
1609 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Changed the `say' client operation's interface to accept
1612 new `type' argument to indicate the type of the message sent
1613 by the library. The application may filter the library's
1614 messages according the type. The affected file is the
1615 lib/silcclient/silcapi.h.
1617 * Added two new functions to lib/silcclient/silcapi.h:
1618 silc_client_del_client and silc_client_del_client_by_id.
1619 Affected file lib/silcclient/idlist.c.
1621 * Moved the clientincludes.h from includes/ to silc/ and
1622 serverincludes.h from includes/ to silcd/.
1624 * The modes for the CMODE and CUMODE are now passed as
1625 uint32 for application with COMMAND_REPLY. The affected
1626 file is lib/silcclient/command_reply.c.
1628 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1630 * /WHOIS without arguments shows client's own information.
1631 Affected file lib/silcclient/command.c.
1633 * Changed PING to not accept any arguments. The specs
1634 says that client can ping only the connected server so
1635 requiring an argument is not needed. Affected file is
1636 lib/silcclient/command.c.
1638 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Fixed a fatal bug in private message sending and reception
1641 encryption and decryption when using private message keys.
1642 The implementation was incorrect and did not follow the
1643 specification. It causd that some of the message were
1644 lost since it did not use the sending and receiving keys
1645 as the protocol suggests. This has been fixed and will cause
1646 incompatibilities with older clients when sending private
1647 message encrypted with private message keys. Affected files
1648 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1649 and various other in Irssi SILC Client.
1651 Added `responder' boolean argument to the functions
1652 silc_client_add_private_message_key[_ske] to indicate when
1653 the key is added as responder or initiator of the key
1656 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1658 * Removed the silc_ske_check_version function and created
1659 a SilcSKECheckVersion callback. Added also a function
1660 silc_ske_set_callbacks that is now used to set all SKE
1661 callbacks. The callback functions are not given to
1662 the SKE functions anymore, but this function is used to
1665 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1667 * Added `silc_version' argument to the silc_client_alloc
1668 to define the version of the application for the library.
1669 The library will use the version string to compare it
1670 against the remote host's (usually a server) version
1671 string. Affected file lib/silcclient/silcapi.h
1673 * Added the KE protocol context to Key Agreement context
1674 in client library so that we can abort the SKE if it
1675 is in process when we get timeout. Affected file is
1676 lib/silcclient/client_keyagr.c.
1678 * Do not resolve the client ID forever if it returns in the
1679 first time that such client does not exist. This was done
1680 for example with private message. Affected file is
1681 lib/silcclient/client_prvmsg.c.
1683 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Do not add regex.h for WIN32. The affected file
1686 includes/silcincludes.h.
1688 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1689 not work yet 100%. It generates the DLL's automatically
1690 when compiling with --with-win32 under cygwin.
1692 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * lib/contrib/regex.c is not compiled on WIN32.
1696 * Added silc_net_get_socket_opt function to the
1697 lib/silcutil/silcnet.h.
1699 * Added includes/silcwin32.h for WIN32 specific includes
1702 * Do not use ptime structure or any of the posix process
1703 functions on WIN32 in lib/silccrypt/silrng.c.
1705 * Added silc_gettimeofday to provide generic function
1706 for struct timeval on all platforms. Added the function
1707 to lib/silcutil/silcutil.h.
1709 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1712 library as they clearly belong there. As a plus side we
1713 can make the actual socket connection routines platform
1716 Added also new generic function silc_socket_read and
1717 silc_socket_write (that used to be silc_packet_[read/write].
1718 The implementation of these are platform specific.
1720 * Added WIN32 specific routines of silc_socket_[read/write]
1721 to lib/silcutil/win32/silcwin32sockconn.c.
1723 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * Added preliminary support for native WIN32 compilation under
1726 cygwin (using the -mno-cygwin option for GCC) to the
1727 ./configure.in.pre. The --with-win32 now prepares the
1728 compilation for native WIN32.
1730 * Rewrote the SILC Scheduler interface in the file
1731 lib/silcutil/silcschedule.h. The scheduler is now context
1732 based and does not have anymore any global static scheduler.
1733 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1734 and created lib/silcutil/win32 directory for WIN32 based
1737 * Added Unix specific network routines to the
1738 lib/silcutil/unix/silcunixnet.c and the old
1739 lib/silcutil/silcnet.c includes now only generic routines.
1741 Added WIN32 specific network routines to the
1742 lib/silcutil/win32/silcwin32net.c.
1744 * Added Unix specific utility functions from the
1745 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1747 * Added WIN32 SILC Scheduler to the file
1748 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1751 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Do not handle JOIN notify in the server if the target client
1754 is not registered (idata->registered == FALSE). The affected
1755 file is silcd/packet_receive.c.
1757 * Update the nickrec->founder in event_cumode in the Irssi SILC
1758 client. Affected file irssi/src/silc/core/silc-channels.c.
1760 * Fixed the CUMODE_CHANGE notify handling in the server when
1761 server and router are announcing their clients on channels.
1762 Now the mode changes are saved and notified correctly. The
1763 affected file is /silcd/packet_receive.c.
1765 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1766 They really did not replace the cache entry in the ID Cache.
1767 Now they do that. Affected file silcd/idlist.c.
1769 * Fixed the KICK notify handling in the Irssi SILC client to
1770 update the channel records so that the kicked client does not
1771 appear to be on the channel. The affected file is
1772 irssi/src/silc/core/silc-channels.c.
1774 * Always update the conn->current_channel when executing command
1775 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1777 * Fixed the KILL notify handling in Irssi SILC client to remove
1778 the killed client on all channels.
1780 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Fixed the silc_parse_command_line to remove extra spaces
1783 from the start and end of the arguments. Affected file is
1784 lib/silcutil/silcutil.c.
1786 * Cancel and free any active protocol in the function
1787 silc_server_close_connection. Affected file silcd/server.c.
1789 * Cancel and free any active protocol in the function
1790 silc_client_close_connction. Affected file is
1791 lib/silcclient/client.c.
1793 * Do not execute the KILL command for clients that are in
1794 history (ie. they are not in the network). Affected file is
1797 * Fixed KILL notify handling, client does not crash anymore.
1798 Affected file irssi/src/silc/core/silc-channels.c.
1800 * Reduced the default packet buffer size from 2048 to 1024 in
1801 lib/silccore/silcpacket.c.
1803 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1804 counter to the SKE context that is incresed when the SKE library
1805 performs async operation outside the library. If the outside
1806 process frees the SKE context and FREED status will be set
1807 and the library will detect after the sync operation that the
1808 libary is freed. The affected files are
1809 lib/silcske/silcske[_status].[ch].
1811 * Resolve the client entry information in the function
1812 silc_client_channel_message to assure that NULL pointer is not
1813 passed as client entry to the application. */
1815 * Fixed the task timeout calculation to assure that there is
1816 never negative timeouts. The affected file is
1817 lib/silcutil/silcschedule.c.
1819 * Fixed the channel user mode notification sending in server.
1820 It was sent point-to-point to the router (or to server by router)
1821 but it needs to be destined to a channel. The routines now
1822 supports sending the channel user mode notifys to the channels
1823 when announcing clients and channels. Affected files are
1824 silcd/server.c and silcd/packet_receive.c.
1826 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1827 It did not actually replace the old channel entry in the cache.
1828 Affected file lib/silcclient/client_notify.c.
1830 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * Fixed a possible crash in silc_packet_send_prepare. It now
1833 assures always that there is enough space in the buffer and
1834 at the tail area of the buffer (for MAC).
1836 Fixed the inbound buffer reallocation in silc_packet_read.
1837 It was old code and did not handle the reallocation correctly.
1840 The affected file is lib/silccore/silcpacket.c.
1842 * Fixed buffer overflow in silc_parse_nickname in the file
1843 lib/silcutil/silcutil.c.
1845 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1847 * make install generates new server keys only if there is not
1850 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1853 Added check that if the NOREPLY is set then we will not send
1854 the away message. This avoids infinite loop of away messages
1855 if both clients are away. The affected file is
1856 lib/silcclient/client_prvmsg.c.
1858 * Fixed client crash if /NICK was given without arguments.
1859 Affected file lib/silcclient/command.c.
1861 * Server does not send the invite list in INVITE command back
1862 to the client if the list was not altered. Added this notion
1863 to the protocol spec as well. Affected file silcd/command.c.
1865 Fixed possible crash in INVITE command by checking the
1866 value of silc_server_get_client_route command.
1868 * Fixed the INVITE notify type handling. The arguments are now
1869 taken in correct order and client does not crash. The affected
1870 file is irssi/src/silc/core/silc-channels.c.
1872 Removed the "Inviting xxx to channel" message from the
1873 client library away and let the application handle it.
1874 Affected file lib/silcclient/command.c. Added that message
1875 to Irssi SILC client's message formats.
1877 * Fixed CMODE command crash in client. It now checks the
1878 amount of arguments correctly and does not crash. The affected
1879 file is lib/silcclient/command.c.
1881 * Do not create new channel automatically in silc_channels_join
1882 but check whether the channel by that name already exists.
1883 Affected file irssi/silc/core/silc-channels.c.
1885 * Do not send the SERVER_SIGNOFF to router if the disconnected
1886 entity was the router. Affected file silcd/server.c.
1888 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1889 SILC client as it was missing from there.
1891 Added the handling of the KICK notify to the Irssi SILC client
1892 as it was missing. Added "you have been kicked" message to
1893 Irssi SILC client's message modules formats.
1895 Added the handing of the KILL notify to the Irssi SILC client
1896 as it was missing. Added the kill message module formats
1899 The affected file is irssi/src/silc/core/silc-channels.c.
1901 * The router did not save the channel mode the server announced.
1902 Affected file silcd/packet_receive.c.
1904 * Fixed a possible crash in INFO command in server. If the
1905 server did not provide the server info it crashed. Affected
1906 file silcd/command.c.
1908 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Fixed the GETKEY command in the server to check also the
1911 global list. Otherwise the GETKEY would not work correctly
1912 in normal SILC server. Affected file silcd/command.c.
1914 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Fixed GETKEY crash, it crashed if the command did not succseed.
1918 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1921 is now real and not just an macro interface to GMP.
1923 Removed the entire GMP from the source tree and imported new
1924 NSS MPI library instead. Reason for removing GMP is that it is
1925 extremely large and compiles extremely slow. The NSS MPI
1926 is only a few files and compiles in less than 10 seconds.
1927 The speed is also about the same as GMP. The MPI is imported
1928 to lib/silcmath/mpi.
1930 If the system has GMP installed we will still use the GMP.
1931 If it is not then the NSS MPI will be compiled.
1933 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1935 * Merged a long nickname (127 characters long) crash bugfix from
1936 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1938 * Merged a freed memory reference bugfix from Irssi CVS tree.
1939 Affected file irssi/src/core/commands.c.
1941 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Added the server's public key sving and verification to the
1944 server when performing the SKE. This was missing and the
1945 remote server's (or router's) public key was accepted without
1946 checking whether we have it previously or trust it at all.
1947 Affected file silcd/protocol.c.
1949 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1951 * Check in the silc_server_timeout_remote if protocol is active
1952 and make sure that the protocol's final callback is called so
1953 that all memory if freed. Affected file silcd/server.c.
1955 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * silc_server_whois_send_reply crashed the server if the nickname
1958 was 127 characters long. Affected file silcd/command.c.
1960 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1962 * Added sanity check to the silc_server_new_client. If the hostname
1963 is provided inside username then check that the provided hostname
1964 really is the same as the resolved one. If the hostname was not
1965 resolved then check it from the public key. Affected file is
1966 silcd/packet_receive.c.
1968 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1969 if the server disconnected us and the connection is not valid
1970 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1972 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1973 the library to the lib/silcutil/silcutil.[ch].
1975 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1977 * Close log file after open. Affected file
1978 lib/silcutil/silclog.c.
1980 * Check whether sock == NULL in silc_client_send_packet and return
1981 if it is. Affected file lib/silcclient/silcclient.c.
1983 * Check rec->entry == NULL in the Irssi SILC Client before
1984 sending the channel message. Affecte file is
1985 irssi/src/silc/core/silc-servers.c.
1987 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Merged a splitted window bugfix from Irssi CVS tree. The
1990 affected file is irssi/src/fe-text/textbuffer-view.c.
1992 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1993 It did not print nickname.
1995 * Improved the distributions system a bit.
1997 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
2000 irssi/src/fe-text/gui-window.c.
2002 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
2003 to in-active server. The affected file is
2004 irssi/src/silc/core/client_ops.c.
2006 * Resolve the client in USERS command reply if the entry does
2007 not have username resolved. The affected file is
2008 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
2009 command to WHOIS command to really resolve stuff. The USERS
2010 is not used any more in any critical section so WHOIS can
2011 be used even though it might be slower than IDENTIFY.
2013 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
2016 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2018 * Changed the protocol API a bit more consistent in the
2019 lib/silccore/silcprotocol.[ch].
2021 * Changed the following headers to ROBODoc format:
2023 lib/silccore/silcpayload.h
2024 lib/silccore/silcprotocol.h
2025 lib/silccore/silcsockconn.h
2027 All core library headers are now formatted.
2029 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Fixed a bug in Irssi SILC client; do not show that you are
2032 server/router operator if you really are not. Affected file is
2033 irssi/src/silc/core/client_ops.c.
2035 * Renamed silc_command_free_payload to silc_command_payload_free.
2036 Affected file lib/silccore/silccommand.h
2038 * Added silcmath.h to include the prototoypes of various routines
2039 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2042 * Changed the following headers to ROBODoc format:
2044 lib/silccore/silcchannel.h
2045 lib/silccore/silccommand.h
2046 lib/silccore/silcid.h
2047 lib/silccore/silcidcache.h
2048 lib/silccore/silcmode.h
2049 lib/silccore/silcnotify.h
2050 lib/silccore/silcpacket.h
2051 lib/silcmath/silcmath.h
2053 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Added checking to the server code not to start the server if
2056 ciphers and stuff are not configured properly. Affected files
2057 silcd/serverconfig.[h] and silcd/server.c.
2059 * Changed the layout of the header files of the public interfaces
2060 in the SILC libraries. The new layout supports ROBODoc
2061 documentation tool (and some others) so that it is easy to create
2062 a library reference manual. All the other headers and source
2063 code must still follow the CodingStyle document. Also source
2064 code must not include these ROBODoc stuffs, only the headers.
2065 Furthermore, all public interface headers must now be named
2066 by using `silc' prefix, example: silcapi.h, silccipher.h.
2067 Some files were renamed due to this. All the other headers
2068 must not be used as public interfaces. I will update the
2069 CodingStyle document later. Changed following headers, so far:
2071 lib/silcclient/silcapi.h
2072 lib/silccore/silcauth.h
2073 lib/silccore/silcprivate.h
2074 lib/silccrypt/silcdh.h
2076 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2080 * Removed silc_client_packet_send_flush from the client library
2081 as it is not needed. Affected file lib/silcclient/client.[ch].
2083 * Added printing of message of unresolved authentication method
2084 to the Irssi SILC client. Added it to the module formats.
2085 Removed the same message from the client library.
2087 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2089 * Added new distribution feature, DISTLABEL. Every distribution
2090 can define own preprocessor label that can be used in the
2091 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2092 file distributions, acconfig.h.pre and prepare.
2094 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * Added Makefile.defines_int to include the actual definitions
2097 for Makefile.defines.in. Tested the new distribution system,
2098 created distributions and tested installation.
2100 * Added AWAY message printing to the Irssi SILC client. Added
2101 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2103 * Added SCONNECT command to call the SILC's CONNECT command.
2104 Cannot use CONNECT directly since Irssi uses that internally.
2105 Affected file irssi/src/silc/core/silc-servers.c.
2107 Added ACTION local command. It is same as ME command but takes
2108 the channel as mandatory argument.
2110 Rewrote some of the Irssi's help files to suite for SILC
2113 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2115 * Added Makefile.defines[.in] that should for now on be included
2116 in all Makefile.am file in the source tree. That file includes
2117 all common compilation definitions for SILC source tree.
2119 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Minor changes to the ./prepare script to change the package
2122 name according the distribution name to the configure.in.
2124 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Created new distribution system. Added file `distributions'
2127 that defines all the distributions that can be created out of
2128 the SILC source tree. The ./prepare script now reads that
2129 file to determine how to prepare the distributions. The
2130 first argument to the ./prepare is the name of the distribution
2131 and second is the version of the distribution. If given
2132 without arguments it creates the default (toolkit) distribution
2133 with the default version (defined in ./prepare).
2135 All Makefile.am files that are subject to the distributions
2136 are now named as Makefile.am.pre. These are ./Makefile.am
2137 and lib/Makefile.am. Others may be changed later.
2139 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Added invite list, ban list, some key management and connection
2142 error message printing to module formats in the Irssi SILC client.
2144 * Added new silc_client_set_away_message to set the away message
2145 that is back to the person who sent private message. The
2146 affected file lib/silcclient/silcapi.h and the
2147 lib/silcclient/client_prvmsg.c.
2149 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Fixed the private message sending in the Irssi SILC client,
2152 added local command KEY to the Irssi SILC client.
2154 Added key management and key agreement message formats to the
2155 irssi/src/fe-common/silc/module-formats.[ch].
2157 Added USERS (alias WHO) printing, server/router operator
2158 indication and LIST command printing to the module formats.
2160 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2162 * Fixed channel joining notify handling, cumode notify handling
2163 from Irssi SILC client.
2165 * Added SILC specific module-formats to the Irssi SILC client so
2166 that SILC specific message hilighting, colors etc is possible.
2167 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2169 Added channel mode, channel user mode, actions, notices,
2170 whois and whowas printing to the the module-formats.c.
2172 * Fixed a bug in channel deletion in the server. The channel
2173 is not left to the cache even if the channel founder auth mode
2174 is set when there are no users anymore on the channel. Affected
2175 file silcd/server.c.
2177 * The silc_net_localhost now resolves the entire hostname including
2178 the domain name. Affected file lib/silcutil/silcnet.c.
2180 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2182 * Changed the ask_passphrase client operation to be ascynchronous.
2183 It has now a completion callback and a context that the
2184 application must call after it has got the passphrase from
2185 the user. Affected files lib/silcclient/silcapi.h,
2186 lib/silcclient/protocol.c, lib/silcclient/command.c and
2189 Added SilcAskPassphrase callback that the application calls
2190 to deliver the passphrase to the library.
2192 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2193 The public key verification and especially a certificate
2194 verification is asynchronous procedure.
2196 Added new SILC_SKE_STATUS_PENDING status to indicate the
2197 request is pending and a callback will be called to finalize
2200 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2201 indicate that remote end did not send its public key (or
2202 certificate), even though we require it. Added check for this
2203 condition in the SKE. This was a security bug, now fixed.
2205 Defined new SilcSKEVerifyCbCompletion callback that is called
2206 when the verification process is completed.
2208 The affected files lib/silcske/silcske_status.h and
2209 lib/silcske/silcske.[ch].
2211 * Changed the verify_public_key client operation to be async
2212 as well. Defined SilcVerifyPublicKey callback that is used to
2213 indicate the success of the public key verification process.
2215 Changed the server and client to use the new async client
2218 * Changed the Irssi SILC client's internal scheduler to be called
2219 twice as many times as it used to be. As a result the client
2220 should be a bit faster now. Affected file is
2221 irssi/src/silc/core/silc-core.c.
2223 * Added support to Irssi SILC client of asynchronous public key
2224 verification and passphrase inquiry. Affected file is
2225 irssi/src/silc/core/silc-core.c.
2227 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * Do not say "You have left channel %s" in client library.
2230 Moved it to the application. Affected files are
2231 lib/silcclient/command.c and silc/client_ops.c.
2233 * Fixed silc_client_get_clients. Command context was not
2234 duplicated and was freed memory in the callback. Affected
2235 file lib/silcclient/idlist.c.
2237 * Do not say "you are now talking..." on JOIN command in the
2238 client library. The appliation must handle it.
2240 * Do not say ".. changed topic to" in command reply in the
2241 client libary. The application must handle it.
2243 * Fixed TOPIC command sending in the client library.
2245 * Fixed a memory leak in silc_client_command_free in the file
2246 lib/silcclient/command.c.
2248 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2250 * Imported a modified version of Irssi client to the source tree.
2251 The Irssi will be used to create a new client called
2252 Irssi SILC. Imported to irssi/.
2254 Added silc_core_init_finish function to the Irssi. Affected
2255 file irssi/configure.in.
2257 A lot changes in the Makefile.ams around the irssi tree.
2259 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Do not rehash if the new size is same as the old size of the
2262 hash table, in the silc_hash_table_rehash*. The affected file
2263 lib/silcutil/silchashtable.c.
2265 * Replaced hash_table_del_by_context calls from the server
2266 (when channel->user_list and client->channels) to the
2267 hash_table_del as it is sufficient and faster.
2269 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Added silc_hash_table_list, silc_hash_table_get and the
2272 SilcHashTableList structure to provide an alternative way to
2273 traverse the hash table. The affected files are
2274 lib/silcutil/silchashtable.[ch].
2276 * Changed the server's idlist routines to use the hash table
2277 routines to optimize the code.
2279 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2281 * Replaced the client entry's `channel' list and channel entry's
2282 `user_list' list to hash tables for optimized lookup. Changed
2283 the code to use the hash table interface around the code.
2284 Affected file lib/silcd/idlist.[ch].
2286 * Added `auto_rehash' boolean argument to the function
2287 silc_hash_table_alloc to indicate whether the hash table should
2288 auto-rehash when it thinks is appropriate time. It will
2289 increase the hash table size if the there is twice as much
2290 entries in the table than the size of the table, and will
2291 decrease the size if there are twice as less entries than
2292 the size of the table.
2294 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2298 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2300 * silc_idcache_purge_by_context deletes the entry now by context
2301 as it is supposed to do. Affected file lib/silccore/idcache.c.
2303 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2304 client is not anymore valid (WHOWAS givens the info) and not
2305 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2307 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2309 * Removed the `data' and `data_len' arguments from the ID Cache
2310 interfaces and added `name' argument. ID Cache does not handle
2311 anymore the binary data only a names associated with given ID.
2313 * When hashing a Client ID with silc_hash_id the entire ID is
2314 not hashed anymore, instead only the hash of the Client ID is
2315 hashed. This way we can access the Client ID from the cache
2316 with Client ID but with the hash of the ID (which is a hash of
2317 the nickname) as well without any difference in performance.
2319 Added also silc_idcache_find_by_id_one_ext to do one on one
2320 searching when we have the actual ID. Added also function
2321 silc_hash_client_id_compare. The affected files are
2322 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2324 * When hashing the name associated with a ID it is always done
2325 in lowercase. This way we can access the cache without worrying
2326 about case-sensitivity, even though, for example nicknames are
2329 * Fixed a bug in server with channel message sending. It put
2330 wrong ID type as destination ID. The affected file
2331 silcd/packet_send.c.
2333 * silc_idcache_del_by_context now deletes from all hash tables
2334 by context. Affected file lib/silccore/idcache.c.
2336 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2338 * Changed the client library to use the new ID Cache interface.
2339 Changes around the source tree.
2341 * Added silc_hash_table_rehash_ext to rehash with specific
2342 hash function. Affected file lib/silcutil/silchashtable.[ch].
2344 * Added silc_hash_string_compare to compare two strings in the
2345 hash table. Affected file lib/silcutil/silcutil.[ch].
2347 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Added new function silc_idcache_del_by_context into the
2350 lib/silccore/idcache.[ch].
2352 * Changed the server's ID list routines to use the new ID Cache
2353 interface. Changes around the source tree.
2355 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2357 * Added silc_hash_table_del[_by_context]_ext functions in to the
2358 lib/silcutil/silchashtable.[ch].
2360 Removed silc_hash_table_find_all* routines and added new
2361 silc_hash_table_find_foreach to replace them.
2363 Added silc_hash_table_replace_ext function as extended
2364 replacing function. Separated the simple hash table interface
2365 from the extended hash table interface in the file
2366 lib/silcutil/silchashtable.h.
2368 * Fixed minor bugs and changed it to use some of the new
2369 hash table functions in lib/silccore/idcache.c
2371 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Added new function silc_hash_table_find_all to return all keys
2374 in the hash table by the specified key. As the hash table is
2375 collision resistant it also makes it possible to have several
2376 duplicate keys in the hash table. This function may be used to
2377 find all of the keys from the hash.
2379 Added user_context arguments to the SilcHashFunction,
2380 SilcHashCompare and SilcHashDestructor to deliver user specified
2383 Added new fuctions silc_hash_table_find[_all]_ext to do
2384 extended lookup with specified hash and compare functions and
2385 specified user contexts.
2387 Added new function silc_hash_table_add_ext to add the key
2388 with specified hash function and user context.
2390 Added new function silc_hash_table_foreach to traverse all
2391 entrys in the hash table. Added SilcHashForeach callback
2394 Added new function silc_hash_table_del_by_context to delete
2395 the entry only if the context associated with the key matches.
2397 Affected files are lib/silcutil/silchashtable.[ch].
2399 * Removed silc_hash_[server/client/channel]_id and added just
2400 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2401 silc_hash_id_compare to compare two ID's using as the hash table
2402 comparison function. Added also silc_hash_data to hash
2403 binary data and silc_hash_data_compare to compare it.
2405 * Removed silc_idlist_find_client_by_hash as it is not needed
2406 anymore. Affected file silcd/idlist.[ch].
2408 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2409 to use internally the SilcHashTable. The new ID Cache is a lot
2410 faster than the old one. Some of the ID Cache interface was also
2411 rewritten and obsolete and stupid functions were removed.
2413 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Added entry_count field to the SilcHashTable to keep the number
2416 of the entries in the table. Implemented the function
2417 silc_hash_table_rehash. Added new function
2418 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2420 Fixed a minor bug in silc_hash_table_free.
2422 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2423 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2424 into the lib/silcutil/silcutil.[ch].
2426 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Implemented a collision resistant hash table into the
2429 lib/silcutil/silchashtable[ch]. See the header and the source
2430 for the SilcHashTable API.
2432 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2434 * Merged dotconf version 1.0.2 into lib/dotconf.
2436 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Do not compile anything in lib/silcsim/* if the SIM support
2439 is not enabled. The tree should now compile without problems
2442 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2444 * Compiled the SILC under cygwin. Compiled and tested briefly
2445 without problems. More tests needed. The SIMs didn't compile
2448 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2450 * Fixed possible crash in silc_get_username in the
2451 lib/silcutil/silcutil.c.
2453 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * Fixed a va_arg in silc/client_ops.c.
2457 * Oops, RC5 routines were named AES and caused some problems
2458 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2460 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Added new SilcIDIP structure into the lib/silccore/id.h and
2463 replaced the old `ip' fields from all SILC ID's to that type.
2464 This is a step towards IPv6 support.
2466 The silc_id_get_len takes now the ID as an extra argument.
2467 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2468 both IPv4 and IPv6 based ID's.
2470 The affected files are lib/silccore/id.[ch] and other files
2471 around the tree using these routines.
2473 * Removed the ID length arguments in server from various
2474 silc_server_send_notify_* routines -> they are not needed
2477 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Fixed memory leak in silc_encode_pem_file in the file
2480 lib/silcutil/silcutil.c.
2482 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2484 * Check minor version as well in the SKE. Affected files are
2485 silcd/protocol.c and lib/silcclient/protocol.c.
2487 * Added --identifier option to the server so that an identifier
2488 can be when creating the public key for the server. Affected
2489 file is silcd/silcd.c.
2491 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2492 lib/silccrypt/silcpkcs.c.
2494 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * Register default ciphers and stuff when using -C option with
2497 the server. Affected file sildc/silcd.c.
2499 * Put back the servers public key filename format, it is better
2500 than the new one. For now, the client keys are saved with the
2501 new filename format. The affected file silc/client_ops.c.
2503 * Implemented the Cipher API for the rest of the ciphers that
2504 did not implement it or implemented it the wrong way.
2506 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Register default ciphers and stuff when using the -S option
2509 in the client. Affected file silc/silc.c. Same also when
2510 creating new key pair with -C option.
2512 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Fixed the silc_verify_public_key client operation function to
2515 save the public keys differently. The fingerprint is now
2516 used as filename and not the hostname. This way also the
2517 client keys are saved uniquely and not with hostnames. The
2518 affected file is silc/client_ops.c.
2520 * Trimmed the silc_hash_fingerprint function to remove extra
2521 whitespaces from the end of the fingerprint. The affected
2522 file is lib/silccrypt/silchash.c.
2526 * Added silc_cipher_register_default function to register all
2527 default ciphers. It can be used when configuration files
2528 does not exist and the application does not want any specific
2529 ciphers in any specific order.
2531 The SilcDList is now used as silc_cipher_list dynamically
2532 allocated cipher list. Removed the static list all together
2533 and now all ciphers must be allocated to the dynamic list.
2534 The silc_cipher_alloc routine was changed to check only the
2537 All silc_cipher_* routines that used to return int returns
2540 The affected files lib/silccrypt/silccrypt.[ch].
2542 * The same thing was done to silc_hash_* as for silc_cipher_*
2543 routines. Affected files lib/silccrypt/silchash.[ch].
2545 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2546 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2547 Added also silc_pkcs_[un]register[_default] functions.
2548 Removed the data_context from the PKCS API.
2550 * Added silc_hmac_register_default function to register default
2551 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2552 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2553 to unregister all hmacs at once.
2555 * Register the default ciphers, hash functions, PKCSs and HMACs
2556 if client's configuration file does not exist. The affected
2559 * The client did not load the hash functions from the SIM
2560 modules at all. Added support for this. Affected file is
2561 silc/clientconfig.c.
2563 * When decoding public key with silc_pkcs_public_key_decode, check
2564 the supported algorithm only if PKCS are registered. Affected
2565 file lib/silccrypt/silcpkcs.c. The same was done with the
2566 silc_pkcs_private_key_decode.
2568 * Fixed the SILC List routines to keep the list always in order.
2569 It used to change the list's order when traversing the list but
2570 not it preserves the order. Affected file lib/trq/silclist.h.
2572 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Added the client library to use the SilcSocketConnection's
2575 reference counter (by silc_socket_dup) to prevent the bug that
2576 the socket object may be freed underneath async operation.
2578 * The name resolv library checking fixes in the configure.in.pre.
2581 * Created new version of the protocol drafts for future
2582 development. The -03 drafts are the ones that will be changed
2583 in the trunk now and the -02 will remain as they are.
2585 * Send list of CUMODE notifys to the router when announcing
2586 the channel users to the router. Affected file silcd/server.c.
2587 If the router receiving channel founder CUMODE for a channel
2588 that already has channel founder it will send CUMODE notify
2589 to the sender to remove the channel founder rights from the
2590 announced client. Affected file silcd/packet_receive.c.
2592 * The CUMODE notify may now use Server ID as well as the entity
2593 who changes the mode. Updated protocool specs.
2595 * Updated INSTALL and README files.
2597 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * New web pages in the http://silc.pspt.fi. The pages was
2604 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2606 * Implemented the [DenyConnectin] config section in the server.
2607 Added silc_server_config_denied_conn to check whether incoming
2608 connection is denied. Affected file silcd/serverconfig.[ch].
2610 * Do not check the ports when checking the incoming configuration
2611 data if the port is 0, meaning any. Affected file is
2612 silcd/serverconfig.c.
2614 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Fixed buffer overflow in silc_string_compare in the file
2617 lib/silcutil/silcutil.c.
2619 * Fixed double free in silc_server_command_leave in the file
2622 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Fixed the version checking in the server. Affected file is
2627 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Fixed the configuration data fetching when accepting new
2630 connections in the server. Affected file silcd/server.c.
2632 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2634 * Added `sender_entry' argument to the function
2635 silc_server_packet_relay_to_channel so that we can check
2636 whether some destination actually belongs to the same route
2637 the sender belongs (ie, we must not resend the packet to the
2638 sender). Affected file silcd/packet_send.[ch].
2640 * Added `servername' field to the SilcClientEntry in the server
2641 to hold the name of the server where client is from. Affected
2642 file is silcd/idlist.h.
2644 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2646 * Moved the channel message encrypting in the router betwen
2647 router connections from silc_server_channel_message to the
2648 silc_server_packet_relay_to_channel since we want to check
2649 whether we have anybody channel before encrypting anything.
2650 Affected files silcd/packet_[receive/send].c.
2652 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Fixed the [AdminConnection] server config section to support
2655 multiple entries. Affected file silcd/serverconfig.c.
2657 * Added support into the server to check the validity of the
2658 incoming connection before executing any KE or authentication
2661 * The connection configuration is now saved to the KE and
2662 connection auth protocol contexts and not fetched anymore in
2663 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2665 * The local hosts listenning address and port is also resolved
2666 now when starting the server. We want to have the socket object
2667 to include the real address and port for the listener. Added
2668 new function silc_net_check_local_by_sock into the files
2669 lib/silcutil/silcnet.[ch].
2671 * Fixed a broadcast bug in server -> do not broadcast if we
2674 * Fixed a routing bug. Do not route broadcast packets ever.
2675 Broadcast packets must be processed always and not routed since
2676 they may be destined to some other host than yourself and thus
2677 would get routed without no good reason. Affected file is
2680 * Added function silc_server_config_is_primary_route to check
2681 whether primary router connection has been configured (a router
2682 configuration that we are initiating). If there is not, we
2683 will assume that there is only two routers in the SILC network
2684 and we will use the incoming router connection as our primary
2685 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2687 * Changed the order of the broadcasting. Broadcast _after_ the
2688 packet has been processed not before. Affected file is
2691 * Fixed a [ClientConnection] parsing bug. The port was never
2692 parsed correctly thus resulting to port 0. Affected file
2693 silcd/serverconfig.c.
2695 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2696 argument and did not set the broadcast packet flag. Affected
2697 file silcd/packet_send.c. Fixed same bug in the function
2698 silc_server_send_notify as well.
2700 * If we receive NEW_ID packet for our own ID in the server, ignore
2703 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2707 * Removed the nickname from the Private Message Payload.
2708 Updated the code and the protocol specs.
2710 * Updated protocol specs for submitting to the IETF.
2712 * Tweaked the Random Number Generator a bit. Affected file
2713 lib/silccrypt/silcrng.c. Exported a new function
2714 silc_rng_[global]_add_noise which can be used to add more
2717 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2719 * Do not parse packets with different timeout when protocol
2720 is active -> may cause problem with rekey. Affected file
2723 * When server receives signoff notify it must not create
2724 new channel key if the client is on any channels since the
2725 sender of the signoff notify will create it.
2727 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2729 * Added printing of error messages during SKE protocol from the
2730 failure packet sent by server during SKE. Affected file
2733 * Removed the client's failure_callback handling with timeout
2734 and handle it immediately when received.
2736 * The SKE library returned wrong type in SUCCESS and FAILURE
2737 packets. They must be 32 bit MSB not 16 bit MSB.
2739 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Ok, rewrote the logic of the re-key and now it seems to work.
2742 I tested it on high traffic with frequent re-keys without
2743 problems. Added hmac_receive (and renamed hmac to hmac_send)
2744 in SilcClientConnection in lib/silcclient/client.h and
2745 in SilcIDListData in silcd/idlist.h. Also, removed the
2746 SilcPacketParserContext's cipher and hmac fields as they are
2747 not needed anymore and actually caused some problems when
2748 the ciphers and hmac's changed underneath the packet parser.
2750 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2752 * If re-key protocol is active then process the incoming packets
2753 synchronously since we must assure that icoming packets encrypted
2754 with the old key is processed before the new keys is set to
2755 use. This is true other packets than for REKEY packets.
2756 Affected file silcd/server.c. The same was done to client library
2757 as well, affected file lib/silcclient/client.c.
2759 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2761 * Fixed bug in client and server to accept the force send if
2762 the packet is send from silc_[server/client]_packet_process
2763 function. Otherwise the packets are never delivered, oops.
2765 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Disable force sending of packets when REKEY protocol is active.
2768 We must assure that no packet is sent directly when rekey is
2769 performed. All packets must be sent through packet queue.
2770 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2771 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2772 function is silc_[server/client]_packet_send_real to check
2775 * Replaced the SIM paths from example config files to
2776 /usr/local/modules. Also, make install creates now
2777 /usr/local/silc/logs directory to hold all the SILC server
2780 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2782 * Made the configure.in.pre work on Solaris. Patch by salo.
2784 * Made all ciphers compatible with non-x86 machines. Defined
2785 CBC mode macros into lib/silccrypt/ciphers_def.h.
2787 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2789 * Fixed the make install.
2791 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * When MAC computation fails the silc_packet_decrypt returned 0
2794 even though it was supposed to return -1. Fixed this. The
2795 affected file is lib/silccore/silcpacket.c.
2797 * Do not replace the config files in /etc/silc (in make install)
2798 if they already exist. Affected file ./Makefile.am.
2800 * Do not send re-key packets immediately but through packet queue.
2801 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2803 * Changed silc_net_check_host_by_sock to return FALSE if the
2804 IP/DNS could not be resolved. Though, it returns the IP address
2805 now even if it could not resolve it (but returns also FALSE).
2806 Affected file lib/silcutil/silcnet.[ch].
2808 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2810 * Added silc_pkcs_decode_identifier to decode the public key's
2811 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2812 Added also silc_pkcs_free_identifier. Added also new context
2813 SilcPublicKeyIdentifier.
2815 * Added -S option to the silc client. It is used to dump the
2816 contents of the specified public key file.
2818 * Changed the PKCS api to return the public key length when
2819 setting the public key.
2821 * Fixed a fatal bug in the public and private key file loading.
2822 Affected file lib/silccrypt/silcpkcs.c.
2824 * Execute the packet parsing for client with zero (0) timeout
2825 if the protocol is active. Affected file silcd/server.c.
2827 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2829 * Made the key generation options to the silcd program. Added
2830 -C option, equivalent to client's option.
2832 * Added new [ServerKeys] config section to the server. It
2833 configures the server's public and private key.
2835 * Defined generic Public Key Payload into the protocol
2836 specification to send specific type of public keys and
2839 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2840 public key or certificate.
2842 * Implemented the GETKEY command to the server and to the
2843 client library and on user interface.
2845 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2847 * Made preliminary `make install' work.
2849 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2851 * Added SilcServerRekey context into silcd/idlist.h.
2853 * Added the PFS support as defined in the specification to the
2854 SKE protocol. Affected files lib/silcske/*.c.
2856 * Added `ske_group' field to the SilcServerRekey context to hold
2857 the number of the SKE group that is used with PFS in re-key.
2858 Affected file silcd/idlist.h.
2860 * Added PFS re-key support to the server. Affected file is
2863 * Added silc_protocol_cancel to cancel execution of the next
2864 state of the protocol. Affected file is
2865 lib/silccore/silcprotocol.[ch].
2867 * Added the re-key support with and without PFS to the client
2868 library. Re-key is performed once in an hour, by default.
2870 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2871 Added silc_client_rekey_callback and silc_client_rekey_final.
2872 Affected files are lib/silcclient/protocol.[ch] and
2873 lib/silcclient/client.[ch].
2875 * Removed the `hmac_key' and `hmac_key_len' fields from the
2876 SilcClientConnection structure; not needed. Affected file is
2877 lib/silcclient/client.h.
2881 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2883 * Do not ask whether user wants to use the negotiated private key
2884 for private messages, just use it. Affected file is
2885 silc/local_command.c.
2887 * Added `send_enc_key' and `enc_key_len' fields to the
2888 SilcIDListData structure since they are needed in the re-key
2889 phase. Affected file is silcd/idlist.[ch].
2891 * Implemented the simple re-key protocol into the server.
2892 Affected files silcd/server.c and silcd/protocol.[ch]. The
2893 re-key will be performed once in an hour, by default.
2895 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2896 Added silc_server_rekey, silc_server_rekey_callback and
2897 silc_server_rekey_final.
2899 * Removed Tunneled flag from the protocol. Updated the code
2900 and the specifications.
2902 * Adde `pfs' field to the SilcIDListData to indicate whether
2903 the PFS is to be performed in the re-key. Affected file is
2906 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2909 int64 of at least the xintXX size. If void * is less that 4
2910 bytes uint32 * will be used. Defined bool as boolean.
2912 * Changed _ALL_ unsigned long and unsigned int to uint32,
2913 unsgined short to uint16 in the source tree.
2915 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2916 not handle clients that has entry->data.registered == FALSE.
2917 They are not in the network anymore. Affected file is
2920 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2922 * Implemented the sending of the SERVER_SIGNOFF notify in the
2923 server. Affected file is silcd/server.c.
2925 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2926 Added also silc_notify_payload_encode_args into the
2927 lib/silccore/silcnotify.[ch].
2929 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2930 Affected file silcd/packet_receive.c.
2932 * Implemented the SERVER_SIGNOFF notify handling in the client
2933 library. Affected file lib/silcclient/client_notify.c. Also,
2934 implemnted the printing of the SERVER_SIGNOFF info to the
2935 application. Affected file silc/client_ops.c.
2937 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2938 if the deleting was successful. Affected file silcd/idlist.[ch].
2940 * Added support for public key authentication in the connection
2941 authentication protocol in the client library. Affected file
2942 lib/silcclient/protocol.c.
2944 * Changed the server's silc_idlist_get_clients_by_* interface
2945 to support already allocated array so that new entries may be
2946 added to pre-allocated array. Affected file silcd/idlist.[ch].
2947 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2948 and command replies.
2950 * All command reply functions in the server now calls the
2951 pending command callback even if error occured. This way the
2952 error will be delivered to the client as well. Affected files
2953 silcd/command.c and silcd/command_reply.c.
2955 * Fixed INFO command to return local server's info if no server
2956 was provided. Affected file lib/silcclient/command.c.
2958 * Removed RESTART command for good. Updated the code and the
2961 * Rewrote parts of the task system. It is a bit simpler now.
2962 Removed unsued task priorities. The affected files are
2963 lib/silcutil/silctask.[ch].
2965 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Moved the USERS printing from the library to the application.
2968 Affected files lib/silcclient/command.c and silc/client_ops.c.
2970 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Added channel key re-key support. The re-key is perfomed
2975 only by the router and is done once in an hour. Added `rekey'
2976 field to the SilcChannelEntry in the server. Affected files
2977 silcd/server.c and silcd/idlist.h.
2979 * Added silc_task_unregister_by_context into the file
2980 lib/silcutil/silctask.[ch].
2982 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2984 * Added SILC_UMODE_GONE mode to indicate when the client is not
2985 present in the SILC network. Added also support to the local
2986 command AWAY that will set this mode. Added support of showing
2987 "xxx is gone" in WHOIS command. The USERS command shows the
2988 gone status as well.
2990 * Fixed setting server and router operator privileges in the
2991 server's UMODE command. Affected file silcd/command.c.
2993 * Merged the SKE KE1 and KE2 payloads into one payload. The
2994 new KE payload is equivalent to the old KE2 payload.
2996 Cleaned up the SKE Start Payload parsing. It now uses the
2997 simple buffer unformatting to do the parsing. A lot faster
3000 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
3001 to the SKE that is used to indicate whether both of the SKE
3002 parties should perform authentication. By default only the
3003 responder performs authentication. By setting this flag also
3004 the initiator must do authentication. By default it is unset
3005 since in normal SKE case, client to server connection, only
3006 the responder should do authentication. When doing SKE between
3007 two clients both should perform authentication. Updated the
3008 code and the protocol specs.
3010 * A little fix to IDENTIFY command in the server. Search the
3011 client first by hash not nickname. Affected file is
3014 * Fixed the silc_client_close_connection to support closing
3015 the client to client connections wihtout deleting too much
3016 data. Affected file lib/silcclient/client.c.
3018 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3019 are received if protocol used to be active but is not anymore
3020 the application would crash due to NULL pointer dereference.
3021 Affected files silcd/server.c and lib/silcclient/client.c.
3023 * Added `hash' field to the SilcClientConnection to include
3024 the hash function negotiated in the SKE protocol.
3026 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3027 to set the channel founder authentication data. A client can
3028 claim the founder rights later by providing the authentication
3029 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3030 This way the channel founder can regain the channel founder
3031 privileges even it is left the channel. This works only on
3032 local server and the client must be connected to the same
3033 server to be able to regain the founder rights. Updated the
3034 protocol specs accordingly.
3036 Added support to the CMODE command in the client to set the
3037 founder auth data. Read the README to see how to set it.
3039 Added support to the CUMODE command to claim the founder
3040 rights. Read the README to see how to do it.
3042 Added support for the founder authentication to the Channel
3043 Entry in the server. Affected file silcd/idlist.h.
3045 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3046 server's CMODE command. Affected file silcd/command.c.
3048 * Added the following new functions into lib/silccore/silcauth.[ch]:
3049 silc_auth_get_method and silc_auth_get_data.
3051 * The server now saves the remote hosts public key to the
3052 SilcIDListData pointer. Affected file silcd/protocol.c.
3054 * The normal server now does not remove the channel entry from
3055 the cache if the founder authentication data is set. It used
3056 to remove it if the founder was the last one on the channel on
3057 the server and left the channel. The auth data is saved and
3058 if the channel is re-joined later the old entry is used with
3059 the old auth data. Affected files silcd/command_reply.c and
3062 * Removed the `pkcs' field from the SilcIDListData structure
3063 in the server; it is not used. Affected file silcd/idlist.h.
3065 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Fixed packet processing on slow links. Partial packets were
3068 never re-processed because the incoming data buffer was cleared
3069 by the application. Application must not directly clear the
3070 sock->inbuf, the packet processing routines handle it. Fixed
3071 this in client library and in server.
3073 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * Fixed the WHOIS and IDENTIFY send reply function to really
3076 check whether to send list or just one entry. Affected file
3079 * Cleaned up the LEAVE command's channel key distribution. The
3080 affected file silcd/command.c.
3082 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3083 can enforce the channel mode as well. In that case the ID
3084 includes the ID of the server. The code now enforces the
3085 mode change if the router have different mode than the server.
3087 * The notify client operation with CMODE_CHANGE notify can now
3088 return NULL client_entry pointer if the CMODE was not changed
3089 by client. Application must check for this.
3091 * Added <Server ID> argument to INFO command to support server
3092 info fetching by Server ID.
3094 * Added silc_server_announce_get_channel_users to get assembled
3095 packets of channel users of the specified channel. Affected
3096 file silcd/server.[ch].
3098 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3099 was freed underneath the ID Cache.
3101 * Re-announce clients when the server received CHANNEL_CHANGE
3102 notify from the router. Affected file silcd/packet_send.c.
3104 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3106 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3107 crashed since it did not handle the fact that there is no cipher
3108 called "3" and didn't check the error condition. Now fixed.
3110 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3111 flag. It can be used to send message requests.
3113 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3115 * Implemented the RESTART command in the client.
3117 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3118 notice type messages. Added notice printing to the user
3121 * The channel keys are not re-generated if the channel's mode
3122 is PRIVKEY, ie private key on the channel exists. Affected
3123 files silcd/server.c and silcd/command.c.
3125 * Fixed a little bug in channel message delivery when channel
3126 private keys are set in the server. Affected file is
3127 silcd/packet_send.c.
3129 * Changed the setting on channel->on_channel = TRUE from the
3130 silc_client_save_channel_key to the JOIN command reply. The
3131 key payload is not received if the private channel key is set.
3132 Affected file lib/silcclient/command_reply.c and the
3133 lib/silcclient/client_channel.c.
3135 * When the CMODE_CHANGE notify is sent and the channel private
3136 key mode is removed the channel key must be re-generated in
3137 other cells as well. Added this support for the router in the
3138 silcd/packet_receive.c.
3140 * Added new local command NOTICE to send notice message on
3141 channel. Affected file silc/local_command.[ch].
3143 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3145 * Added new local command ME to the client. It is used to send
3146 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3147 some action. Affected file silc/local_command.[ch].
3149 * Changed channel_message and private_message client operations
3150 to deliver the message flags to the application. Added also
3151 the `flags' arguments to the silc_client_send_channel_message
3152 and silc_client_send_private_message functions. Affected file
3155 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3157 * Redefined the Private Message Payload to support private message
3158 keys and to support the new private message flags. Updated
3159 the protocol specs. Flags makes it possible to have for example
3160 CTCP style messages.
3162 * Added new type SilcPrivateMessagePayload and defined an API
3163 for it in the lib/silcclient/silcprivate.[ch].
3165 * Tested private message private keys successfully. Tested the
3166 private message key set, unset and list commands with the new
3169 * Redefined the Channel Message Payload to include the channel
3170 message flags (equal with private message flags) to support
3171 for example CTCP style messages.
3173 * Defined some of the message (for channel and private message)
3174 flags. Updated the protocol specs and added the flags to the
3175 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3177 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3179 * Added SilcKeyAgreementStatus type to the key agreement routines
3180 to indicate the current status and error if one occured.
3181 The status types are defined in the lib/silcclient/silcapi.h.
3183 * Added new local command KEY that is used to set and unset private
3184 keys for channels, set and unset private keys for private messages
3185 with remote clients and to send key agreement requests and
3186 negotiate the key agreement protocol with remote client. The
3187 key agreement is supported only to negotiate private message keys,
3188 it currently cannot be used to negotiate private keys for channels,
3189 as it is not convenient for that purpose.
3191 * Fixed a minor pending callback setting bug in the function
3192 silc_client_get_client_by_id_resolve, now the function works.
3193 Affected file lib/silcclient/idlist.c.
3195 * Added function silc_net_get_local_port to get local bound
3196 port by socket. Added to lib/silcutil/silcnet.[ch].
3198 * Added `sockets' and `sockets_count' fields to the SilcClient
3199 object. They hold the sockets of the listenning sockets in
3200 the client. Listenning sockets may be for example the key
3201 agreement server. Affected file lib/silcclient/client.[ch].
3202 Added functions the silc_client_add_socket and the
3203 silc_client_del_socket. They are exported to the application
3206 * Added ~./silc/clientkeys to support other client's public keys.
3208 * Renamed verify_server_key client operation to verify_public_key
3209 and added one argument to indicate the type of the connection
3210 (server, client etc.).
3212 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3214 * Added silc_server_connection_auth_request to handle the
3215 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3216 silcd/packet_receive.[ch].
3218 * Added silc_server_send_connection_auth_request into the
3219 silcd/packet_send.c to send the connection auth request packet.
3221 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3224 * Fixed the public key authentication in responder side in the
3225 server. The `auth_data' pointer includes the SilcPublicKey
3226 not the path to the public key. Affected file silcd/protocol.c.
3228 * Implemented the public key authentication in the initiator side
3229 in the server. Affected file silcd/protocol.c.
3231 * Removed the [RedirectClient] config section from the server
3232 configuration. Is not needed and I don't want to implement it.
3234 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3236 * Cleaned up the CMODE command in the server. It now works
3237 correctly and supports all the modes defined in the protocol.
3238 Affected file is silcd/command.c.
3240 * Added `hmac_name' field to the SilcChannelEntry in the server
3241 to hold the default HMAC of the channel. It can be set when
3242 creating the channel (with JOIN command). Affected files
3245 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3246 type to indicate the change of the current cipher and hmac
3247 on the channel. Client can safely ignore the <cipher> argument
3248 (if it chooses to do so) since the CHANNEL_KEY packet will
3249 force the channel key change anyway. The <hmac> argument is
3250 important since the client is responsible of setting the new
3251 HMAC and the hmac key into use.
3253 * Fixed the CMODE command in the client library as well.
3255 * Tested CMODE command in router environment successfully.
3257 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3259 * Show the version of the remote client (or server) when connecting
3260 to the server. It is logged to the log file. Affected file
3261 is silcd/protocol.c.
3263 * Fixed the KILLED notify handling in the client library. The
3264 client must be removed from all channels when receiving the
3267 Also, do not remove the client entry when giving the KILL
3268 command but when the KILLED notify is received.
3270 * Removed silc_idlist_find_client_by_nickname from the server.
3271 Not needed anymore. Affected files silcd/idlist.[ch].
3273 * Implemented the CHANNEL_CHANGE notify type handling to the
3274 server. Affected file silcd/server.c.
3278 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3280 * Added silc_server_send_notify_invite to send the INVITE
3281 notify between routers.
3283 * Implemented the INVITE command correctly to the server.
3285 * Implemented the INVITE notify type handling in the server.
3287 * Implemented the INVITE command to the client library and on the
3290 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added function silc_server_get_client_resolve to find the
3293 client entry by ID from all ID lists and then resolve it
3294 (using WHOIS) if it cannot be found. Affected file is
3297 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3299 * Implemented the BAN command to the client library.
3301 * The JOIN command in the server now checks the invite list
3304 * Changed the silc_command_reply_payload_encode_va and the
3305 silc_command_payload_encode_va to support that if argument is
3306 NULL it ignores and checks the next argument. Affected file
3307 lib/silccore/silccommand.c.
3309 * Added silc_server_send_notify_ban to send the BAN notify
3310 type between routers.
3312 * Chaned the silc_notify_payload_encode to support that if
3313 argument is NULL it ignores and checks the next argument.
3314 Affected file lib/silccore/silcnotify.c.
3316 * Tested ban lists in router environment successfully.
3318 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Implemented BAN command to the server, in silcd/command.[ch].
3322 * Removed the BAN and INVITE_LIST modes from the CMODE command
3325 * Added function silc_string_match to regex match two strings.
3326 Affected files lib/silcutil/silcutil.[ch].
3328 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Redefined parts of the SilcChannelEntry in the server to support
3331 the new ban and invite lists.
3333 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3335 * Redefined the INVITE command. The same command can be used to
3336 invite individuals to the channel but also to manage the invite
3337 list of the channel (to add to and remove from the invite list).
3338 Updated the protocol specs.
3340 * Added new command SILC_COMMAND_BAN that can be used to manage
3341 the ban list of the channel. Updated the protocol specs.
3343 * Removed the channel modes: the SILC_CMODE_BAN and the
3344 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3345 in the CMODE command. The equivalent features are now available
3346 using INVITE and BAN commands. Updated the protocol specs.
3348 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3349 in the network about change in the current ban list. The notify
3350 type is not used by the client.
3352 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3353 support the invite lists.
3355 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3357 * Added new function silc_string_regexify that converts string
3358 including wildcard characters into regex string that can
3359 be used by the GNU regex library. Added into the file
3360 lib/silcutil/silcutil.[ch].
3362 Added silc_string_regex_combine to combine to regex strings
3363 into one so that they can be used as one regex string by
3364 the GNU regex library. Added into the file
3365 lib/silcutil/silcutil.[ch].
3367 Added silc_string_regex_match to match two strings. It returns
3368 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3370 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * Imported GNU regex to the soruce tree into lib/contrib.
3373 Fixed some compiler warning from the regex.c.
3375 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Fixed MOTD command in the server to work in router environment.
3379 * Fixed the MOTD command in the client library to support
3380 the server argument in the command.
3382 * Added `nickname_len' argument to the silc_idlist_add_client
3383 in the server, as the `nickname' argument may be binary data
3386 * Added silc_idlist_get_channels to return all channels from
3389 * Implemented LIST command to the server. Affected file is
3392 * Implemented the LIST command to the client library and on the
3395 * Added [<user count>] argument to the LIST command reply.
3396 With private channels the user count is not shown.
3398 * Updated TODO and README.
3400 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3402 * The client entry's data.registered must be TRUE even with
3403 global client entry on global client list. The data.registered
3404 is used to check whether the client is anymore in the network,
3405 for example with WHOWAS command so it must be valid.
3407 * Fixed the WHOWAS command in the server. It now actually works
3408 in router environment. Added function into silcd/command_reply.c
3409 silc_server_command_reply_whowas_save.
3411 * Added silc_idlist_purge function to the silcd/idlist.c
3412 to periodically purge the ID Cache.
3414 * Fixed INFO command in the server. It works now in router
3415 environment. Added <server name> argument to the INFO command
3416 reply. Updated the protocol specs.
3418 * Fixed minor bug in silc_idcache_purge to not purge if the
3419 expire value is zero.
3421 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3422 they were buggy because of the WHOWAS information.
3424 * Fixed local command MSG to handle the async resolving of
3425 the remote client properly. It used to fail the first MSG.
3426 Affected file silc/local_command.c.
3428 * Added `data_len' field to SilcIDCache context.
3430 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3432 * Update TODO. Todo in commands in the server.
3434 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3437 used by routers as broadcast packet to inform other routers
3438 about the changed user mode.
3440 Implemented the notify handling in the server. Affected file is
3441 silcd/packet_receive.c. Added the function
3442 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3444 * Added new generic Channel Payload and deprecated the New Channel
3445 Payload. The New Channel Payload is now the generic Channel
3448 * Added new argument `mode' to the silc_server_send_new_channel
3449 as it is required in the Channel Payload now.
3451 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3452 and created a new and real SilChannelPayload to represent the
3453 new generic Channel Payload. Implemented the encode/decode
3454 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3456 * Added silc_server_get_client_channel_list to return the list
3457 of channels the client has joined for WHOIS command reply.
3458 Affected file silcd/server.[ch].
3460 * Implemented the channel list sending in the WHOIS command reply
3461 in server and in the client.
3463 Implemented the channel list displaying on the user interface
3464 as well. Affected file silc/client_ops.c.
3466 * Added silc_channel_payload_parse_list to parse list of Channel
3467 Payloads. It returns SilcDList list of SilcChannelPayloads.
3468 Client for example can use this function to parse the list of
3469 channels it receives in the WHOIS command reply. The caller
3470 must free the list by calling silc_channel_payload_list_free.
3471 Affected files lib/silccore/silcchannel.[ch].
3473 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3475 * Added one new argument <user mode> to the WHOIS command reply
3476 to return the mode of the user in SILC. Updated the protocol
3479 Implemented it to the server and client.
3481 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Fixed the mode printing on the user interface on joining.
3484 Affected file silc/client_ops.c.
3486 * Implemented the UMODE command and user modes in general to the
3487 client library and to the user interface.
3489 * Implemented the UMODE command to the server.
3491 * The server now sends UNKNOWN_COMMAND error status if client sends
3492 unknown command. Affected file silcd/command.c.
3494 * All server commands now handle the command identifier the right
3495 way when sending the command reply to the client. The client can
3496 use to identify the command replies with the identifier.
3498 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3500 * Added silc_server_get_client_route to resolve the route to
3501 the client indicated by the client ID. Affected file is
3504 * Added silc_server_relay_packet as general function to relay
3505 packet to arbitrary destination. This deprecates functions
3506 like _send_private_message_key, _relay_notify etc. Affected
3507 file is silcd/packet_send.[ch].
3509 Removed silc_server_send_key_agreement,
3510 silc_server_send_private_message_key and
3511 silc_server_packet_relay_notify functions from the file
3512 silcd/packet_send.[ch].
3516 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3517 server. Affected file silcd/packet_receive.[ch].
3519 * Implemented the KILL command to the client. Implemented the
3520 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3521 Affected files lib/silcclient/command[_reply].c and
3522 lib/silcclient/client_notify.c. Implemented the KILL notify
3523 printing in the user inteface.
3525 * Fixed a lot silc_parse_nick memory leaks from the client
3526 library in the file lib/silcclient/command.c.
3528 * Changed the silc_server_send_notify_on_channels's `sender'
3529 argument from SilcSocketConnection to SilcClientEntry to
3530 check the sender as entry and not as connection object and not
3531 to send to the client provided as argument. The affected file
3532 is silcd/packet_send.[ch].
3534 * The notify packets that are destined directly to the client used
3535 to not to be processed by the server. Now changed that and the
3536 server processes all notify packets. After relaying the packet
3537 to the client the notify packet is processed in the server.
3539 * The silc_server_free_client_data now checks whether there is
3540 pending outgoing traffic for the client and purges the data to
3541 the network before removing the client entry.
3543 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3546 an client is killed from the SILC Network. Updated the protocol
3549 Added new function silc_server_send_notify_killed to the
3550 silcd/packet_send.[ch].
3552 * Added function silc_server_packet_relay_notify to relay notify
3553 packets that are destined directly to a client. In this case
3554 the server does not process the notify packets but merely relays
3555 it to the client. Affected file silcd/packet_send.[ch].
3557 Added also silc_server_packet_process_relay_notify to check
3558 whereto relay the notify. Affected file is
3559 silcd/packet_receive.[ch].
3561 * Implemented the KILL command to the server.
3565 * Added the backup schema desgined last fall to the protocol
3566 specs for everyone to see. The specification is in the
3567 *-spec-xx.txt draft and the packet type definitions for the
3568 backup routers is in *-pp-xx.txt draft. Thusly, added also
3569 new packet type SILC_PACKET_CELL_ROUTERS.
3571 * A big security problem in the implementation discovered. The
3572 signoff of an client did not cause new channel key generation
3573 which it of course should've done. The channel keys must be
3574 always re-generated when client leaves (or signoffs) the channel.
3575 The silc_server_remove_from_channels funtion now handles
3576 the channel key re-generation.
3578 * Added `sender' argument to the silc_server_send_notify_on_channels
3579 to not to send the client provided as argument. Affected file
3580 silcd/packet_send.[ch].
3582 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3584 * Implemented OPER and SILCOPER commands into the server and
3587 * Added silc_auth_verify and silc_auth_verify_data to verify
3588 the authentication directly from the authentication payload.
3589 It supports verifying both passphrase and public key based
3590 authentication. Affected file lib/silccore/silcauth.[ch].
3592 * Added `hash' field to the SilcIDListData structure. It is the
3593 hash negotiated in the SKE protocol. Affected file is
3596 * Slight redesigning of the SilcAuthPayload handling routines.
3597 Do not send SilcPKCS but SilcPublicKey as argument.
3599 * Implemented the public key authentication support to the
3600 serverconfig. The public key is loaded from the provided path
3601 and saved as authentication data to void * pointer. Thus,
3602 changed the unsigned char *auth_data to void *auth_data;
3604 * Fixed SHUTDOWN command to send the reply before the server
3605 is shutdown. :) Affected file silcd/command.c.
3607 * Fixed fatal bug in CONNECT command. The hostname was invalid
3608 memory and server crashed. Affected file silcd/command.c.
3610 * Fixed fatal bug in CLOSE command. The server_entry became
3611 invalid but was referenced later in the command. Affected file
3614 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Fixed fatal bug in failure packet handling. Server ignored
3617 the failure and thus crashed when it came.
3621 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3624 that the command may be executed only once in (about) 2 seconds.
3625 The old SILC_CF_LAG flag is same but allows command bursts up
3626 to five before limiting.
3628 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3629 server code. Various commands now includes the CF_LAG_STRICT
3630 flag to disallow any kind of miss-use of the command.
3632 * Fixed the silc_buffer_unformat to not to allocate any data
3633 if the length of the data is zero. It used to allocate the
3634 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3636 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3638 * Changed the format of AdminConnection configuration section
3639 in the server. Added username of the admin to the format.
3640 Affected files silcd/serverconfig.[ch].
3642 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3643 to return admin configuration data by host, username and/or
3646 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Implemented WHOWAS command to the server. Added the functions:
3650 silc_server_command_whowas_parse,
3651 silc_server_command_whowas_send_reply,
3652 silc_server_command_whowas_from_client and
3653 silc_server_command_whowas_from_server
3655 * Added <Client ID> argument to the WHOWAS command reply. Updated
3656 the protocol specs accordingly.
3658 * Implemented WHOWAS command and command_reply to the client
3661 Implemented the WHOWAS printing on the user interface.
3663 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3665 * Added new argument to the WHOWAS command reply, the real name.
3666 It is an optional argument. Updated the protocol specs.
3668 * Added SilcIDCacheDestructor callback that is registered when
3669 the SilcIDCache is allocated. The callback is called when
3670 an cache entry in the ID Cache expires, or is purged from the
3671 cache. Added into lib/silccore/idcache.[ch].
3673 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3674 to destruct the client entries when the cache entry expires.
3675 Other ID Cache's in server and in the client library ignores
3678 * If the ID Cache entry's `expire' field is zero then the entry
3679 never expires. Added boolean `expire' argument to the
3680 silc_idcache_add function in the lib/silccore/idcache.[ch].
3681 If it is TRUE the default expiry value is used.
3683 * Added silc_server_free_client_data_timeout that is registered
3684 when client disconnects. By default for 5 minutes we preserve
3685 the client entry for history - for WHOWAS command.
3687 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3689 * Added support to the server to enforce that commands are not
3690 executed more than once in 2 seconds. If server receives
3691 commands from client more frequently, timeout is registered
3692 to process the commands. Affected file silcd/command.c.
3693 Added new function silc_server_command_process_timeout.
3695 * Changed NICK_NOTIFY handling in client library to check that
3696 if the client's nickname was changed, so there is no need to
3697 resolve anything from the server.
3699 * Removed error printing from the WHOIS and IDENTIFY commands.
3700 If error occurs then it is ignored silently in the client library.
3701 The application, however, may map the received error to
3702 human readable error string. The application currently maps
3703 the NO_SUCH_NICKNAME error to string.
3705 * Made the command status message public to the application. Moved
3706 them from lib/silcclient/command_reply.c to
3707 lib/silcclient/command_reply.h. The application can map the
3708 received command status to the string with the
3709 silc_client_command_status_message function.
3711 * Added check to the server to check that client's ID is same
3712 as the Source ID in the packet the client sent. They must
3715 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3717 * Added dist-bzip hook to the Makefile.am to make bzip2
3718 compressed distributions.
3720 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Server now enforces the maximum length for the nickname and
3723 the channel as protocol specification dictates. 128 bytes for
3724 nickname and 256 bytes for channel name.
3726 * Moved the WHOIS printing to the application. The client libary
3727 does not print out the WHOIS information anymore, the application
3728 must do it. Renamed silc_client_command_reply_whois_print to
3729 the silc_client_command_reply_whois_save.
3731 The client's idle time is also sent to the application now, and
3732 the idle is shown on screen.
3734 * Added silc_client_command_reply_identify_save to save the
3735 received IDENTIFY entries.
3737 * Do not check for channel private keys in message sending and
3738 reception if the channel does not have the PRIVKEY mode set.
3739 Affected file lib/silclient/client_channel.c.
3741 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3744 just surfaced after chaning the JOIN procedure.
3746 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Added silc_client_get_clients_by_list to get client entries
3749 from Client ID list, that is returned for example by JOIN
3750 and USERS command replies. The application should use this
3751 function for example when JOIN command reply is received to
3752 resolve the clients already on the channel (library does not
3753 do that anymore as USERS command reply is not used in the JOIN
3754 procedure anymore). Affected files lib/silcclient/silcapi.h and
3755 lib/silcclient/idlist.c.
3757 * JOIN command reply and USERS command reply returns now SilcBuffer
3758 pointers instead of unsigned char pointers when returning
3759 the client list and mode list.
3761 * Added <Client ID> argument to the JOIN command reply, mainly
3762 for the server to identify for which client the command was
3763 originally sent. Updated protocol specs accordingly.
3765 * Added SilcDlist private_key pointer to the SilcChannelEntry
3766 in the client to support the channel private keys. Affected
3767 file is lib/silcclient/idlist.h.
3769 * Added SilcChannelPrivateKey argument to the function
3770 silc_client_send_channel_message so that application can choose
3771 to use specific private ke if it wants to. If it is not provided,
3772 the normal channel key is used, unless private keys are set.
3773 In this case the first (key that was added first) is used
3774 as the encryption key.
3776 * Implemented the support for channel private key handling.
3777 Implemented the following functions:
3779 silc_client_add_channel_private_key,
3780 silc_client_del_channel_private_keys,
3781 silc_client_del_channel_private_key,
3782 silc_client_list_channel_private_keys and
3783 silc_client_free_channel_private_keys
3785 Affected file lib/silcclient/client_channel.c.
3787 * Added the support for the private keys in the channel message
3788 sending and encryption and in the message reception and
3789 decryption. Affected funtions are
3790 silc_client_send_channel_message and silc_client_channel_message.
3792 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Added SKE's key verify callback to the client library's
3795 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3797 * Removed the statement that server (or router) must send USERS
3798 command reply when joining to the channel so that the client
3799 knows who are on the channel. Instead, the client list and
3800 client's mode list is now sent in the JOIN command reply to the
3801 client who joined channel. This is better solution.
3803 * Added function silc_server_get_users_on_channel and function
3804 silc_server_save_users_on_channel to the silcd/server.[ch].
3806 * Removed function silc_server_command_send_users from the
3809 * Do not show topic on the client library anymore. The topic is
3810 sent in the command reply notify to the application and the
3811 application must show the topic now.
3813 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Added client searching by nickname hash into the IDENTIFY and
3816 WHOIS commands in the server as they were clearly missing from
3817 them. Affected file is silcd/command.c.
3819 * Fixed a bug in private message receiving in the client library.
3820 The remote ID was freed and it wasn't supposed, now it is
3823 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3825 * Minor fix to the channel payload; allocate the data area, as it
3826 needs to be of specific length.
3828 * If the key agreement port is zero then the operating
3829 system will define the bound port. Affected files are
3830 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3832 * Added new function silc_channel_payload_decrypt into the file
3833 lib/silccore/silcchannel.[ch].
3835 * Moved the channel message etc, check from silc_packet_decrypt
3836 to applications. The library calls now a generic
3837 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3838 when the packet is either normal or special. This was done to
3839 allow more wide range of checking that was not allowed when
3840 the code was in library. Now applications can do virtually any
3841 checks to the packet and return to the library the decision how
3842 the packet should be processed. Affected files are
3843 lib/silccore/silcpacket.[ch].
3845 Added silc_server_packet_decrypt_check to the server and
3846 silc_client_packet_decrypt_check to the client library.
3848 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3849 to send with specified source and destination information.
3851 * Channel message delivery between routers was broken after the
3852 channel key distribution was fixed earlier. The channel key
3853 was used be to distributed to other routers as well which is not
3854 allowed by the protocol. Now this is fixed and channel keys
3855 really are cell specific and the channel message delivery between
3856 routers comply with the protocol specification.
3858 * Fixed various commands in server to check also the global list
3859 for the channel entry and not just the local list. The affected
3860 file silcd/command.c.
3862 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3864 * Added assert()s to buffer formatting and unformatting routines
3865 to assert (if --enable-debug) when error occurs. Affected
3866 file: lib/silcutil/silcbuffmt.c.
3868 * Changed to auto-reconnect to check whether the remote host is
3869 router and register the re-connect timeout if it is. It used
3870 to check that whether we are normal server, but router must do
3871 auto-reconnect with another router as well. Affected file
3874 * Removed the [<key len>] option from CMODE command as the cipher
3875 name decides the key length, nowadays. See the defined ciphers
3876 from the protocol specification.
3878 * Added [<hmac>] option to the CMODE command to define the HMAC
3879 for the channel. Added SILC_CMODE_HMAC channel mode.
3881 * Added [<hmac>] option for the JOIN command so that user can
3882 select which HMAC is used to compute the MACs of the channel
3885 * Added Hmac field to the Channel Message Payload. The integrity
3886 of plaintext channel messages are now protected by computing
3887 MAC of the message and attaching the MAC to the payload. The
3888 MAC is encrypted. Now, it is clear that this causes some
3889 overhead to the size of the packet but rationale for this is that
3890 now the receiver can verify whether the channel message decrypted
3891 correctly and also when private keys are set for the channel the
3892 receiver can decrypt the packet with several keys and check from
3893 the MAC which key decrypted the message correctly.
3895 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3896 lib/silccrypt/silccipher.[ch].
3898 * Added silc_hash_len to return the digest length into the
3899 lib/silcrypt/silchash.[ch].
3901 * Rewrote parts of Silc Channel Payload interface in the
3902 lib/silccore/silcchannel.[ch]. The encode function now also
3903 encrypts the packet and parse function decrypts it.
3905 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3907 * Fixed a minor formatting bug in the SKE's key material processing.
3908 It actually might have processed the keys wrong way resulting
3911 * Redefined the mandatory HMAC algorithms and added new algorithms.
3912 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3913 and hmac-md5 truncated to 96 bits. The mandatory is now
3914 hmac-sha1-96. Rest are optional (including the one that used
3915 to be mandatory). Rationale for this is that the truncated HMAC
3916 length is sufficient from security point of view and can actually
3917 make the attack against the HMAC harder. Also, the truncated
3918 HMAC causes less overhead to the packets. See the RFC2104 for
3921 * Added new [hmac] configuration section. The SKE used to use
3922 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3923 is of course wrong. The official names that must be proposed in
3924 the SKE are the ones defined in the protocol specification
3925 (hmac-sha1-96 for example). The user can configure any hmac
3926 using any hash function configured in the [hash] section. At
3927 least, the mandatory must be configured.
3929 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3931 * Added HMAC list to the SKE proposal list. It has now both
3932 hash algorithm list and HMAC list. This makes the protocol
3933 incompatible with previous versions. The SKE now seems to work
3934 the way it is supposed to work, for the first time actually.
3936 * Defined plain Hash algorithms to the protocol specification.
3939 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Implemented support for key agreement packets into the server.
3942 Added functions silc_server_key_agreement and
3943 silc_server_send_key_agreement. Other than these functions,
3944 server has nothing to do with this packet.
3946 * Added support for private message key packets into the server.
3947 Added functions silc_server_private_message_key and
3948 silc_server_send_private_message_key.
3952 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3953 called in the protocol's final callback instead in the END
3954 protocol state. This makes a little more sense and in the same
3955 time in client we can use the same protocol routines for normal
3956 key exchange and to key agreement packet handling as well.
3958 * Added to both client's and server's KE protocol context the
3959 SilcSKEKeyMaterial pointer to save the key material. We will
3960 bring the key material to the protocol's final callback by doing
3961 this. The final callback must free the key material.
3963 * Added SKE's packet_send callback into client's KE protocol
3964 context so that the caller can choose what packet sending function
3965 is used. This way we can use different packet sending when
3966 doing normal SKE when doing key agreement packet handling (in
3967 the key agreement packet handling we do not want to encrypt
3970 * Implemented the responder side of the key agreement routines
3971 in the client. The client can now bind to specified port and
3972 accept incoming key negotiation. The key material is passed
3973 to the application after the protocol is over.
3975 * Implemented the processing of incoming Key Agreement packet
3976 in the client. Added function silc_client_key_agreement to
3979 * Implemented the intiator side of the key agreement routines
3980 in the client. The client can now initiate key agreement with
3981 another remote client. The key material is passed to the
3982 application after the protocol is over.
3984 * Created client_keyagr.c to include all the key agreement
3987 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3988 SILC_TASK_CALLBACK except that it is not static.
3990 * Created client_notify.c and moved the Notify packet handling
3991 from the client.[ch] into that file.
3993 * Created client_prvmsg.c and moved all private message and
3994 private message key routines from the client.[ch] into that file.
3996 * Create client_channel.c and moved all channel message and
3997 channel private key routines from the client.[ch] into that file.
3999 * Changed silc_client_get_client_by_id_resolve to resolve with
4000 WHOIS command instead of IDENTIFY command, in the file
4001 lib/silclient/idlist.c.
4003 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Implemented the SKE's responder side to the Client library.
4007 * When FAILURE is received to the protocol do not trust it
4008 blindly. Register a timeout to wait whether the remote closes
4009 the connection as it should do it, only after that process the
4010 actual failure. This was changed to both client and server.
4012 * Added client_internal.h to include some of the structures
4013 there instead of client.h in lib/silcclient/.
4015 * Added function silc_task_unregister_by_callback to unregister
4016 timeouts by the callback function.
4018 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Some "Incomplete WHOIS info" errors has been appearing on the
4021 log files. Took away the entry->userinfo check from WHOIS
4022 reply sending. The entry->userinfo is now " " if client did not
4023 provide one. I thought this was fixed earlier but something
4024 is wrong still. Let's see if the error still appears.
4026 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Fixed a minor bug in the login when the channel key is
4029 re-generated in the server. It used to generate the key in
4030 wrong order and thus caused problems in the channel traffic.
4032 * Fixed a minor bug in channel key distsribution after
4033 KICK command. The key was not sent to the router even though
4036 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Added silc_ske_process_key_material_data as generic routine
4039 to process any key material as the SILC protocol dictates. The
4040 function is used by the actual SKE library but can be used by
4041 applications as well. This relates to the private message keys
4042 and the channel private keys since they must be processed the
4043 same way the normal SILC session keys. The protocol dictates
4044 this. Affected files: lib/silcske/silcske.[ch].
4046 Added also silc_ske_free_key_material to free the
4047 SilcSKEKeyMaterial structure.
4049 * Defined silc_cipher_set_key function to set the key for
4050 cipher without using the object's method function. The affected
4051 files: lib/silccrypt/silccipher.[ch].
4053 * Implemented silc silc_client_add_private_message_key,
4054 silc_client_add_private_message_key_ske,
4055 silc_client_del_private_message_key,
4056 silc_client_list_private_message_keys and
4057 silc_client_free_private_message_keys functions in the
4060 Added functions silc_client_send_private_message_key to send
4061 the Private Message Key payload and silc_client_private_message_key
4062 to handle incoming Private Message Key payload.
4064 * Added Cipher field to the Private Message Key payload to set
4065 the cipher to be used. If ignored, the default cipher defined
4066 in the SILC protocol (aes-256-cbc) is used.
4068 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Removed lib/silcclient/ops.h file.
4072 Redefined parts of the SILC Client Library API. Created new
4073 file silcapi.h that deprecates the ops.h file and defines the
4074 published Client Library API. Defined also private message key
4075 API and channel private key API into the file.
4077 This is the file that the application must include from the
4078 SILC Client Library. Other files need not be included by
4079 the application anymore.
4081 * Added new key_agreement client operation callback and also
4082 defined the Key Agreement library API for the application.
4084 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4087 is used by clients to request key negotiation between another
4088 client in the SILC network. If the negotiation is started it
4089 is performed using the SKE protocol. The result of the
4090 negotiation, the secret key material, can be used for example
4091 as private message key.
4093 Implemented the Key Agreement payload into the files
4094 lib/silccore/silauth.[ch].
4096 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4098 * Redefined ciphers for the SILC protocol. Added some new ciphers
4099 and defined the key lengths for the algorithms. Changed the
4100 code accordingly. The default key length is now 256 bits.
4102 * Fixed SKE key distribution function silc_ske_process_key_material
4103 when the key length is more than 128 bits. The default key
4104 length in SILC is now 256 bits.
4106 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4107 to indicate unsupported algorithm.
4109 * Renamed rijndael.c to aes.c and all functions as well.
4111 * Fixed a long standing channel key setting bug in client library.
4112 Weird that it has never surfaced before.
4114 * Fixed bug in channel deletion. If the entire channel is removed
4115 then it must also delete the references of the channel entry
4116 from the client's channel list as the client's channel entry and
4117 the channel's client entry share same memory.
4119 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4121 * Implemented CONNECT and SHUTDOWN commands in the client.
4123 * Implemented CLOSE command to the client.
4125 * Added the function silc_idlist_find_server_by_name into the
4126 files silcd/idlist.[ch].
4128 Added the function silc_idlist_find_server_by_conn into the
4129 files silcd/idlist.[ch].
4131 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * DIE command was renamed to SHUTDOWN. Updated the both code
4136 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4137 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4139 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4142 * Added function silc_server_create_connection function to create
4143 connection to remote router. My server implementation actually
4144 does not allow router to connect to normal server (it expects
4145 that normal server always initiates the connection to the router)
4146 so the CONNECT command is only good for connecting to another
4149 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4152 or some other client was kicked from the channel.
4154 Implemented the handling of the notify type to both client
4157 Implemented silc_server_send_notify_kicked to send the KICKED
4158 notify. It is used to send it to the server's primary router.
4160 * Implemented the KICK command into server and client.
4162 * Added `query' argument to the silc_idlist_get_client function
4163 to indicate whether to query the client from server or not if
4166 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4167 to indicate that the client is not channel founder.
4171 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Removed the rng context from SilcPacketContext structure and
4174 changed that the packet routine uses the Global RNG API.
4176 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Added support for quit message that client can "leave" on the
4179 channel when it quits the SILC. It is ditributed inside the
4180 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4182 Added silc_server_free_client_data that will take the
4183 signoff message as argument.
4185 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4187 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Updated parts of the protocol specification to keep it up
4192 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4195 payloads in one packet.
4197 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4198 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4199 use now the new List flag.
4201 * Also deprecated the following packet types: REPLACE_ID,
4202 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4204 * Added list support for Notify packet in server.
4206 * Added silc_server_send_notify_channel_change to send the
4207 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4208 the silc_server_send_replace_id.
4210 * Added silc_server_send_notify_nick_change to send the
4211 NICK_CHANGE notify type. Deprecates the function
4212 silc_server_send_replace_id.
4214 * Added silc_server_send_notify_join to send the JOIN notify type.
4215 Deprecates the function silc_server_send_new_channel_user.
4217 * Added silc_server_send_notify_leave to send LEAVE notify type.
4218 Deprecates the function silc_server_send_remove_channel_user.
4220 * Added silc_server_send_notify_cmode and
4221 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4222 types. Deprecates the silc_server_send_set_mode function.
4224 * Added SERVER_SIGNOFF notify type to indicate that server has
4225 quit. This means that all clients on the channel from that
4226 server will drop. This can be also used when netsplit happens.
4228 Deprecated REMOVE_ID packet type since it is not needed anymore
4231 Added silc_server_send_notify_server_signoff to send the
4232 SERVER_SIGNOFF notify type. Deprecates the function
4233 silc_server_send_remove_id.
4235 Added also silc_server_send_notify_signoff to send the
4236 SIGNOFF notify type.
4238 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4239 SILC protocol from this day on. Changed the protocol
4240 specification as well.
4242 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4243 notify type. It is used between routers to notify about
4244 topic changes on a channel.
4246 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4249 * Partly updated the protocol specification to comply with the
4250 changes now made. It is still though a bit outdated.
4252 * The JOIN notify type now takes one extra argument <Channel ID>.
4253 The packet used to be destined to the channel but now the
4254 JOIN type may be sent as list thus it is impossible to
4255 destine it to any specific channel. By adding this argument
4256 it is again possible.
4258 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Added CREDITS file. The CHANGES and CREDITS file will appear
4261 in the distribution as well.
4263 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4266 types in the server's silcd/packet_receive.c.
4268 * Implemented CMODE and CUMODE to work in router environment.
4270 * Fixed minor encoding and decoding buglet from the
4271 lib/silccore/silcmode.c.
4273 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4276 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4278 * Changed all SilcConfigServer* and silc_config_server* to
4279 SilcServerConfig* and silc_server_config*, respectively.
4282 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Associated the ID (client or server ID) to the Authentication
4285 Payload to avoid any possibility of forging. Updated the
4286 protocol specification and the code accordingly.
4288 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * The RSA key length is now save to the RsaKey context in the
4291 key generation process in lib/silccrypt/rsa.c. The key length
4292 is now used to figure out the maximum size of the block allowed
4293 to be encrypted/signed.
4295 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4296 is equivalent to the silc_mp_mp2bin but does not allocate any
4299 * Changed silc_mp_mp2bin API to take length argument. If it is
4300 non-zero then the buffer is allocated that large. If zero, then
4301 the size is approximated using silc_mp_sizeinbase, which however
4304 * Created Global RNG API which is global RNG that application can
4305 initialize. After initializing, any routine anywhere in the
4306 code (including library) can use RNG without allocating a new
4307 RNG object. This was done to allow this sort of use of the
4308 RNG in code that has no chance to allocate RNG object. All
4309 applications currently allocate this and many routines in the
4310 library use this. Affected file lib/silccrypt/silcrng.[ch].
4312 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4313 it to use the Global RNG API.
4315 * Defined Authentication Payload into protocol specification that
4316 is used during SILC session to authenticate entities. It is
4317 used for example by client to authenticate itself to the server
4318 to obtain server operator privileges.
4320 Implemented this payload into the lib/silccore/silcauth.[ch].
4321 Implemented also routines for public key based authentication
4322 as the new protocol specification dictates.
4324 Moved definitions of different authentication methods from
4325 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4327 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4328 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4329 silc_pkcs_verify_with_hash functions into the file
4330 lib/silccrypt/silcpkcs.[ch].
4332 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4334 * The client entry's userinfo pointer must be always valid.
4335 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4336 will fail since it requires the userinfo. Now, the userinfo
4337 is allocated as "" if actual userinfo does not exist. Actually,
4338 it must exist and it is totally Ok to drop client connections
4339 that does not announce the userinfo. However, we will make
4340 this workaround for now.
4342 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4343 to return the remote port by socket.
4345 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4348 SILC_SERVER_PENDING_EXEC and added an new macro
4349 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4350 data or when error occurs while processing the pending command.
4352 Added new argument `destructor' into silc_server_command_pending
4353 and to the SilcServerCommandPending object. This destructor is
4354 now called after calling the pending callback or if error occurs
4355 immediately. If error occurs the actual pending callback won't
4356 be called at all - only the destructor. The destructor may be
4357 NULL if destructor is not needed.
4359 All this applies for client library code as well. Similar
4360 changes were made there as well for the pending commands.
4362 In the client, the application must now allocate the
4363 SilcClientCommandContext with the silc_client_command_alloc
4366 * Added reference counter to the SilcServerCommandContext. Added
4367 function silc_server_command_alloc and silc_server_command_dup
4370 Same type of functions added to the client library for the same
4373 * Removed the cmd_ident from IDListData away since it is now
4374 global for all connections. It is the command identifier used
4375 in command sending and with pending commands. The affected file
4378 * Added reference counter to the SilcSocketConnection objecet to
4379 indicate the usage count of the object. The object won't be
4380 freed untill the reference counter hits zero. Currently only
4381 server uses this, and client ignores it. The client must be
4382 set to use this too later. The affected files are
4383 lib/silccore/silcsockconn.[ch]. Added also the function
4384 silc_socket_dup to increase the reference counter.
4386 This was mainly added because it is possible that the socket
4387 is removed underneath of pending command or other async
4388 operation. Now it won't be free'd and proper DISCONNECTING
4389 flags, etc. can be set to avoid sending data to connection that
4390 is not valid anymore.
4392 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4393 the connection. After that it sets SILC_SET_DISCONNECTED.
4394 It is, however, possible that the socket data is not still freed.
4395 The silc_server_packet_process now checks that data is not
4396 read or written to connection that is DISCONNECTED. The socket
4397 get's freed when the reference counter hits zero.
4399 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Changed the client operation API: channel_message operation's
4402 `sender' is now the client entry of the sender, not the nickname
4403 and the `channel' is the channel entry, not the channel name.
4405 In the private_message operation the `sender' is now also the
4406 client entry of the sender not the nickname.
4408 Affected file is lib/silcclient/ops.h and all applications
4409 using the client operations.
4411 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Moved the calling of ops->connect() from connect_to_server_final
4414 into receive_new_id functin since that is the point when the
4415 client is actually allowed to send traffic to network. The
4416 affected file is lib/silcclient/client.c.
4418 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4421 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4422 (if needs broadcasting) instead of broadcasting the packets one
4423 by one which would make a burst in the network traffic.
4425 * Added `broadcast' argument to the functions in silcd/server.[ch]
4426 silc_server_create_new_channel[_with_id] to indicate whether
4427 to send New Channel packet to primary router.
4429 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added new function into the silcd/server.[ch] files:
4432 silc_server_create_new_channel_with_id to create new channel with
4433 already existing Channel ID.
4435 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4436 lib/silccore/silcpacket.h. This packet is used t send list of
4437 Set Mode payloads inside one packet. Server uses this to set
4438 the modes for the channels and clients on those channels, that it
4439 announced to the router when it connected to it. The protocol
4440 specification has been updated accordingly.
4442 * The silc_server_new_channel did not handle the packet coming
4443 from normal server as it normally does not send that. However,
4444 when it announces its channels it does send it. Implemented
4445 the support for that.
4447 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4448 into the file lib/silccore/id.h.
4450 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Fixed memory leaks in the functions silc_idlist_del_client,
4453 silc_idlist_del_channel and silc_idlist_del_server in the file
4454 silcd/idlist.c. All of those leaked like a sieve.
4456 * Fixed some small memory leaks in the client's function
4457 silc_client_notify_by_server.
4459 * Added functions into silcd/server.c: silc_server_announce_clients,
4460 silc_server_announce_channels and silc_server_announce_server.
4461 These functions are used by normal and router server to announce
4462 to its primary router about clients, channels and servers (when
4463 router) that we own. This is done after we've connected to the
4466 These functions effectively implements the following packet types:
4467 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4468 and SILC_PACKET_NEW_ID_LIST.
4470 * Added new functions into the silcd/packet_receive.[ch]:
4471 silc_server_new_id_list, silc_server_new_channel_list and
4472 silc_server_new_channel_user_list to handle the incoming
4473 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4475 * Added support of changing Channel ID in the function
4476 silc_server_replace_id. If the server that announces a channel
4477 to the router already exists in the router (with same name but
4478 with different Channel ID), router is responsible to send
4479 Replace ID packet to the server and force the server to change
4480 the Channel ID to the one router has.
4482 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4483 client that the Channel ID has been changed by the router. The
4484 normal server sends this to the client. Client must start using
4485 the new Channel ID as the channel's ID.
4487 Implemented handling of this new type into lib/silcclient/client.c
4488 into the function silc_client_notify_by_server.
4490 * Added new function silc_idlist_replace_channel_id into the files
4491 silcd/idlist.[ch] to replace the Channel ID.
4493 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Call silc_server_command_identify_check always when processing
4496 the IDENTIFY command in silcd/command.c
4498 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4501 send keepalive packets. The packet can be sent by clients,
4502 servers and routers.
4504 Added function silc_socket_set_heartbeat into the file
4505 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4506 If not set, the heartbeat is not performed. The actual
4507 heartbeat is implemented in the low level socket connection
4508 library. However, application is responsible of actually
4511 Added silc_server_send_heartbeat to send the actual heartbeat
4512 packet into silcd/packet_send.[ch]. Server now performs
4513 keepalive with all connections.
4515 * Added silc_task_get_first function into lib/silcutil/silctask.c
4516 to return the timeout task with shortest timeout. There was a bug
4517 in task unregistration that caused problems. TODO has been
4518 updated to include that task system must be rewritten.
4520 * The client library will now resolve the client information when
4521 receiving JOIN notify from server for client that we know but
4522 have incomplete information.
4524 * Rewrote parts of silc_server_remove_from_channels and
4525 silc_server_remove_from_one_channel as they did not remove the
4526 channel in some circumstances even though they should've.
4528 * Encryption problem encountered in server:
4530 The LEAVE command used to send the Channel Key packet to the
4531 router immediately after generating it. However, the code
4532 had earlier sent Remove Channel user packet but not immediately,
4533 ie. it was put to queue. The order of packets in the router
4534 was that Channel Key packet was first and Remove Channel User
4535 packet was second, even though they were encrypted in the
4536 reverse order. For this reason, MAC check failed. Now, this
4537 is fixed by not sending the Channel Key packet immediately but
4538 putting it to queue. However, this is more fundamental problem:
4539 packets that are in queue should actually not be encrypted
4540 because packets that are sent immediately gets encrypted
4541 actually with wrong IV (and thus MAC check fails). So, packets
4542 that are in queue should be encrypted when they are sent to
4543 the wire and not when they put to the queue.
4545 However, the problem is that the current system has not been
4546 designed to work that way. Instead, the packet is encrypted
4547 as soon as possible and left to the queue. The queue is then
4548 just purged into wire. There won't be any fixes for this
4549 any time soon. So, the current semantic for packet sending
4552 o If you send packet to remote host and do not force the send
4553 (the packet will be in queue) then all subsequent packets to the
4554 same remote host must also be put to the queue. Only after the
4555 queue has been purged is it safe again to force the packet
4558 o If you send all packets immediately then it safe to send
4559 any of subsequent packets through the queue, however, after
4560 the first packet is put to queue then any subsequent packets
4561 must also be put to the queue.
4563 Follow these rules and everything works fine.
4565 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4567 * Added new function silc_server_remove_clients_by_server to
4568 remove all client entries from ID list when the server connection
4569 is lost. In this case it is also important to invalidate all
4570 client entires as they hold the invalid server entry. This
4571 fixes fatal bug when server has lost connection and will reconnect
4574 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4576 * Made some sanity checks to silc_server_daemonise like to check
4577 whether the requested user and group actually exists.
4579 * Added sanity check to SKE's silc_ske_responder_finish to check
4580 that the public and private key actually is valid.
4582 * Invalidate the client's nickname when receiving Replace ID
4583 packet and the Client ID is being replaced. This means that the
4584 server will query the nickname if someone needs it (client)
4587 * Sort the ID Cache in client library when the ID Cache data
4588 has changed (needs sorting).
4590 * Do not allow for SILC client to create several connections to
4591 several servers. The client does not support windows right now
4592 and generating multiple connections causes weird behaviour.
4594 Irssi-silc client does support windows and can handle several
4595 connections without problems, see: www.irssi.org and SILC plugin.
4597 * Fixed some places where client was added to the IDList. The
4598 rule of thumb is following (in order to get everything right):
4599 If the client is directly connected local client then the
4600 `connection' argument must be set and `router' argument must be
4601 NULL to silc_idlist_add_client function. If the client is not
4602 directly connected client then the `router' argument must
4603 bet set and the `connection' argument must be NULL to the
4604 silc_idlist_add_client function.
4606 * The funtion silc_server_packet_send_local_channel actually did
4607 not check whether the client was locally connected or not. It
4608 does that now. Fixed a bug related to LEAVE command.
4610 * Fixed Remove Channel User payload parsing bug in server's
4611 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4613 * The server's silc_server_save_channel_key now checks also the
4614 global ID list for the channel as it might not be in the local
4615 list. Fixed a bug related to LEAVE command.
4617 * Is this the end of the [<unknown>] buglet that has been lurking
4618 around for a long time? A little for loop fix in server's
4619 silc_server_command_whois_parse that is used by both IDENTIFY
4620 and WHOIS command. At least, this was a clear bug and a cause
4621 of one type of [<unknown>] buglet.
4623 * WHOIS and IDENTIFY commands call the function
4624 silc_server_command_[whois/identify]_check function even if
4625 we are not router server.
4627 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Added --with-gmp configuration option. If set the GMP
4630 is always compiled in the SILC source tree. If not set then
4631 it is checked whether the system has the GMP3 installed. If
4632 it has then the GMP won't be compiled (the system's headers
4633 and library is used), if it doesn't have it then the GMP is
4634 compiled in the SILC source tree.
4636 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Changed RSA private exponent generation to what PKCS #1
4639 suggests. We try to find the smallest possible d by doing
4640 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4641 not security fix but optimization.
4643 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4645 * Added new config entry [Identity] to fork the server and run
4646 it as specific user and group. A patch from Bostik.
4648 * Imported Dotconf configuration library into lib/dotconf.
4649 This will be used to create the SILC configuration files later.
4650 It will appear in the distsribution after this commit.
4652 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * A big code auditing weekend happening. Auditing code for
4655 obvious mistakes, bugs and errors. Also, removing any code
4658 Removed files for being obsolete:
4660 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4661 inline in the file lib/silcutil/silcbuffer.h)
4663 o lib/silcutil/silcbufutil.c (the header has inline versions)
4665 Changed code to fix possible error conditions:
4667 o The buffer formatting routines now check that the destination
4668 buffer really has enough space to add the data. This applies for
4669 both buffer formatting and unformatting
4670 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4671 unformatting was changed to accomodate following rules:
4672 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4673 sent to the function while XXX_*STRING will not allocate or copy
4674 the data into the buffer. Instead it sets the pointer from the
4675 buffer into the pointer sent as argument (XXX_*STRING used to
4676 require that the pointer must be allocated already). This change
4677 makes this whole thing a bit more consistent and more optimized
4678 (note that the data returned in the unformatting with XXX_*STRING
4679 must not be freed now). The routines return now -1 on error.
4681 o Tried to find all code that use buffer_format and buffer_unformat
4682 and added return value checking to prevent formatting and
4683 especially unformatting errors and possible subsequent fatal
4686 o Changed ske->x and ske->KEY to mallocated pointers in
4687 lib/silcske/silcske.h. Fixed possible data and memory leak.
4689 o Added return value checking to all *_parse* functions. Fixed
4690 many memory leaks as well.
4692 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4693 so that buffer overflows would not happen. All code now also
4694 checks the return value as it can fail.
4696 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Added reconnection support to server if the normal server looses
4699 its connection to the router (for example if router is rebooted).
4700 The server performs normal reconnection strategy implemented
4701 to the server. Affected file silcd/server.c.
4703 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4705 * Added new packet type SILC_PACKET_SET_MODE that is used to
4706 distribute the information about changed modes (for clients,
4707 channels and clients channel modes) to all routers in the
4708 network. Updated the protocol specification accordingly.
4710 Added functions into silcd/packet_send.c and
4711 silcd/packet_receive.c: silc_server_send_set_mode,
4712 silc_server_set_mode.
4714 Added new files silcmode.[ch] into lib/silccore that implements
4715 the encoding and decoding of Set Mode Payload. Added new type
4716 SilcSetModePayload. Moved the definitions of different modes
4717 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4719 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4721 * Oops, a little mistake in server's connection authentication
4722 protocol. The protocol is not ended with FAILURE but with
4723 SUCCESS if the authentication is Ok. :) Affected file is
4726 * Implemented NICK_CHANGE notify handling in server in the file
4727 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4728 the local clients on the channel. After the changing nickname
4729 in router environment snhould work and the [<unknown>] nickname
4730 should appear no more.
4732 The silc_server_replace_id function that receives the Replace ID
4733 payload now sends the NICK_CHANGE notify type also in the file
4734 silcd/packet_receive.c
4736 * Changed WHOIS and IDENTIFY command to support the maximum amount
4737 of arguments defined in protocol specs (3328 arguments). This
4738 fixed a bug that caused problems when there were more than three
4741 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4743 * Added extra parameter, command identifier, to the
4744 silc_client_send_command so that explicit command identifier
4747 Changed that ID list routines uses specific command identifier
4748 when sending WHOIS/IDENTIFY requests to the server so that they
4749 can be identified when the reply comes back.
4751 Affected files lib/silcclient/command.[ch],
4752 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4754 * Added `sender' argument to silc_server_packet_send_to_channel
4755 to indicaet the sender who originally sent the packet to us
4756 that we are now re-sending. Ignored if NULL. Affected file
4757 silcd/packet_send.[ch].
4759 * Added some server statistics support in silcd/server_internal.h
4760 SilcServerStatistics structure and around the server code. Also
4761 send some nice statistics information when client is connecting
4764 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4766 * Fixed channel ID decoding in server's JOIN command reply in
4767 silcd/command_reply.c
4769 * Fixed braodcasting of replace ID payload to not to send it if
4770 we are standalone server in silcd/packet_receive.c.
4772 * Fixed all channel message sending routines to not to send
4773 packets to clients that has router set, since they are routed
4774 separately in the same function earlier. Affects file
4775 silcd/packet_send.c and all channel packet sending functions.
4777 * In USERS reply, res_argv[i] are not allocated, the table
4778 is allocated. Thus changed that free the table, not its
4781 * In server's whois_check and identify_check if the client is
4782 locally connected do not send any WHOIS commands - they are not
4785 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Fixed some minor bugs in client when sending WHOIS command. The
4788 arguments was in wrong order.
4790 * Removed statis function add_to_channel from server in
4791 silcd/command.c that was previously used with the joining but
4794 * Tested USERS command in router environment successfully with two
4795 routers, two servers and two clients.
4797 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Reorganized the USERS command and command reply in client library
4800 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4801 When the command is given by user we register a pending command
4802 callback that will reprocess the command after the reply has been
4803 received from the server. When reprocessing the packet we then
4804 display the information. Thus, the USERS information is displayed
4805 now in the command callback instead of in the command reply
4806 callback. The processing of the command is same as previously
4807 when server has sent the command reply in the JOINing process.
4809 * Added to USERS command in silcd/command_reply.c to join the client,
4810 we didn't use to know about, to the channel after we've created
4811 a client entry for it. Also, for clienet we did know already still
4812 check whether it is on the channel or not and add it if not.
4814 * Removed silc_server_command_join_notify as the function and its
4817 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4819 * Changed the client's pending command handling to the same as the
4820 server's pending command handling. It is also now possible to
4821 execute command reply functions from other command reply
4822 function as the function callbacks for commands and command
4823 replies are one and same. The pending commands are not static
4824 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4825 in client connection context. Thus, pending commands are server
4826 connection specific as it is convenient.
4828 Changed the function silc_client_command_pending and
4829 silc_client_command_pending_del and added new function
4830 silc_client_command_pending_check. Removed the
4831 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4834 * Added cmd_ident, current command identifier, to the client
4835 connection context in lib/silcclient/client.h to keep track on
4836 command identifiers used in command sending. Client's command reply
4837 function handling now supports the mandatory command identifiers.
4839 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4840 funtions in client to fully support pending command callbacks.
4842 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4843 as one of the arguments to the application in the command reply
4846 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4847 before first releasing SILC but came back. Now it is removed again
4848 and should come back nomore. The FORWARDED flag was used only
4849 by the JOINing procedure by forwarding the command packet to router.
4850 Now, the JOINing procedure has been changed to more generic (due
4851 to various router environment issues) and FORWARDED is not needed
4852 anymore for anything. The protocol specification is yet to be
4855 Now, removed silc_server_packet_forward from server and the flag
4856 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4858 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4860 * Renamed NAMES command to USERS command. The NAMES was named that
4861 due to historical reasons. Now it is renamed. Also, rewrote
4862 parts of the USERS command. The nickname list is not sent anymore
4863 by the server. Only Client ID and mode lists are sent in the USERS
4864 command. Changed this also to the protocol specification.
4866 The client now resolves the names and stuff after it receives
4867 the USERS list from the server when joining to the channel.
4869 * WHOIS and IDENTIFY commands has been changed to support multiple
4870 Client ID's per command. One can now search for multiple users
4871 in the network by sending only one WHOIS or IDENTIFY command.
4872 Changed the code and the protocol specifications.
4874 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4875 uses silc_server_command_whois_parse to parse the request. */
4877 * If normal server, do not parse the WHOIS and IDENTIFY requests
4878 before sending it to the router. Saves some time.
4880 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Fixed JOIN command on client library. Wrong number of arguments
4883 used to crash the client.
4885 * Added silc_server_channel_has_global function to check whether
4886 channel has global users or not.
4888 * Added silc_server_channel_has_local function to check whether channel
4889 has locally connected clients on the channel.
4891 * The silc_server_remove_from_one_channel now checks whether the
4892 channel has global users or not after given client was removed from
4893 the channel. It also checks whether the channel has local clients
4894 on the channel anymore. If it does not have then the channel entry
4895 is removed as it is not needed anymore.
4897 * The silc_server_notify now checks on JOIN notify whether the joining
4898 client is one of locally connected or global. If it is global then
4899 the channel has now global users on the channel and that is marked
4900 to the channel entry. Also, it now saves the global client to
4901 global list who is joining and JOINs it to the channel. This is
4902 for normal server, that is.
4904 Changed silc_server_send_notify_on_channel,
4905 silc_server_packet_relay_to_channel and
4906 silc_server_packet_send_to_channel check if we are normal server
4907 and client has router set (ie. global client) do not send the
4908 message to that client, as it is already routed to our router.
4910 * Implemented LEAVE notify type handling in silc_server_notify
4913 * Tested LEAVE command in router environment successfully. Tested
4914 with two routers, two servers and two clients.
4918 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4920 * Implemented SIGNOFF notify type handling in silc_server_notify
4923 * silc_server_remove_id now removes the client entry from all channels
4924 it has joined and thusly sends SIGNOFF notify type.
4926 * Rewrote the NAMES list generation in server by removing two excess
4927 loops. The lists are created now inside one loop.
4929 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * silc_server_remove_channel_user checks now also global list
4932 for channel and client.
4934 * silc_server_new_channel_user checks now both local and global
4935 list for channel and client. Fixed a bug in client id decoding.
4936 Used to decode wrong buffer.
4938 * silc_server_channel_message checks now both local and global
4939 list for channel entry.
4941 * Tested channel joining (hence JOIN) in router environment
4942 successfully. Tested with two routers, two servers and two
4945 * Tested channel message sending in router environment successfully.
4947 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Added silc_server_save_channel_key into server.[ch] to save the
4950 received channel key in Channel Key payload processing. It is
4951 also used in JOIN command reply handling.
4953 Equivalent function silc_client_save_channel_key added into
4954 client.[ch] into client library.
4956 * Changed JOIN command reply to send information whether the channel
4957 was created or not (is existing already) and the channel key
4958 payload. Changed protocol specs accordingly.
4960 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4961 the request was sent by ID and not by nickname. Crashed on
4964 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4967 now correctly save the received data.
4969 * silc_server_free_sock_user_data now notifies routers in the
4970 network about entities leaving the network.
4972 At the same time implemented functions silc_server_remove_id
4973 and silc_server_send_remove_id to receive and send REMOVE_ID
4974 packets. The packet is used to notify routers in the network
4975 about leaving entities. The ID removed will become invalid in
4978 * Added function silc_idlist_del_server into server. Removes and
4979 free's server entry from ID list.
4981 * silc_server_private_message function now checks, if we are router,
4982 that the destination ID really is valid ID, naturally.
4984 * In router when NEW_ID packet is received (for new client) the
4985 hash of the Client ID is saved in the ID Cache but the
4986 client->nickname is set to NULL, instead of putting the hash
4989 IDENTIFY command now also checks that client->nickname must be
4990 valid. If it is not if will request the data from the server who
4991 owns the client. Added new function
4992 silc_server_command_identify_check.
4994 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4995 to set the command to already allocated Command Payload.
4997 * Tested private message sending in router environment with two
4998 routers, two servers and two clients. Fixed minor bugs and now
5001 * Fixed segfault from client's NAMES command. Used to crash if
5004 * Forwarded packets must not be routed even if it is not destined
5005 to the receiver. Changed server code comply with this.
5007 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Added `require_reverse_mapping' boolean value to ServerParams
5010 structure. If TRUE (not default) the server will require that
5011 the connecting host has fully qualified domain name.
5013 If the reverse mapping is not required and hostname could not be
5014 found the IP address is used as hostname.
5016 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Implemented version string checking to both client and server.
5019 The check is incomplete currently due to the abnormal version
5020 strings used in development version of SILC.
5022 * Changed all command functions in server to use the new
5025 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Changed char *data to unsigned char *data in ID Cache system to
5028 support binary data as ID Cache data. Changed code to support
5029 binary data in lib/silccore/idcache.c.
5031 * Renamed silc_server_packet_relay_command_reply to
5032 silc_server_command_reply as it is normal packet receiving
5033 function. Rewrote the function to accept command replys for
5034 servers and not only for clients.
5036 * Mark remote router always as registered server if we are connecting
5037 to it. Otherwise, commands sent by the router to us are ignored.
5039 * All ID List find routines now returns the ID Cache Entry pointer
5040 as well if requested.
5042 * WHOIS command works now in router environment, tested with two
5043 routers, two servers and two clients.
5045 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5046 in router environment (as it is almost equivalent to WHOIS) but
5047 hasn't been tested thoroughly. Added new functions:
5049 silc_server_command_identify_parse
5050 silc_server_command_identify_send_reply
5051 silc_server_command_identify_from_client
5052 silc_server_command_identify_from_server
5054 * Disabled route cache adding because adding two different ID's with
5055 same IP replaces the old cache entry thus giving wrong route.
5056 The entry->router->connection is always the fastest route anyway
5057 so route cache may not be needed. Of course, new routes maybe
5058 established after receiving the ID when the entry->router->connection
5059 might not be anymore the most optimal.
5061 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Add route cache for received ID for fast routing.
5065 * Added silc_server_packet_route to route received packet on router
5066 that is not destined to us.
5068 * Renamed silc_server_get_route to silc_server_route_get.
5070 * Added id_string and id_string_len fields into SilcServer to
5071 include encoded ServerID for fast comparing without excess
5072 encoding of the ID's.
5074 * Cleaned up WHOIS command on server side. Added following static
5077 silc_server_command_whois_parse
5078 silc_server_command_whois_check
5079 silc_server_command_whois_send_reply
5080 silc_server_command_whois_from_client
5081 silc_server_command_whois_from_server
5083 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5084 arguments in command replies. All command functions should be
5085 updated to use this macro.
5087 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Minor typo fixes on command reply handling on server.
5091 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added silc_server_command_add_to_channel internal routine to add
5094 the client to the channel after router has created the channel and
5095 sent command reply to the server.
5097 * Added generic silc_server_send_command to send any command from
5100 * Use static buffer with ID rendering instead of duplicating data.
5102 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Fixed a channel user mode bug when joining to a channel server gave
5105 everybody channel founder rights, oops.
5107 * We mark ourselves as the router of the incoming server connection
5108 if we are router ourselves. This way we can check in some packet
5109 sending functions whether it is locally connected server. For
5110 incoming router connections we put NULL.
5112 * For router sending packets locally means now always sending the
5113 packet cell wide; to local clients and local servers. For normal
5114 server sending packet locally means sending it to only local
5117 * Fixed the JOIN command to really work in router environment. If the
5118 channel is created it is always created by the router. Router is
5119 also responsible of making the initial joining to the channel,
5120 sending JOIN notify to the sending server and distributing
5121 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5122 does not exist server doesn't do anything else but forward the
5123 command to the router which performs everything.
5125 * Added silc_server_send_channel_key function to send the Channel Key
5128 * Added silc_server_create_channel_key to create new channel key. The
5129 channel key is now re-generated everytime someone joins or leaves
5130 a channel, as protocol dictates. Note: channel->key_len is the
5133 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5136 packet_receive.[ch] to separate packet sending and receiving
5137 routines. The server.[ch] now includes everything else including
5138 actual packet processing (writing and reading data) and other
5141 Renamed silc_server_private_message_send_internal to
5142 silc_server_send_private_message. The routine is still though
5143 used only to relay private messages as server does not send
5144 private messages itself.
5146 Renamed silc_server_new_channel to silc_server_create_new_channel
5147 and added new function sicl_server_new_channel that handles the
5148 incoming New Channel packet. Added also new sending function
5149 silc_server_send_new_channel to send New Channel Payload.
5151 * Added new function silc_server_notify to process incoming notify
5152 packet to the server/router. Server may then relay the notify
5153 to clients if needed.
5155 * Added new function silc_server_new_channel_user to process incoming
5156 New Channel User packet. Router will redistribute the packet and
5157 send JOIN notify to its local clients and locally connected servers
5158 if needed. Normal server will send JOIN notify to its local client
5159 on same channel when received this packet. Added also corresponding
5160 sending function silc_server_send_new_channel_user to sent the
5163 * Added boolean route argument to send_notif_to_channel and
5164 packet_send_to_channel functions to attempt to route the packet
5165 if it is TRUE and send only locally if it is FALSE.
5167 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * silc_server_replace_id now broadcasts the received replace ID
5170 packet if it is not broadcast packet already. The router must
5171 broadcast to inform other routers about changed ID.
5173 * Added backpointer to server's router into SilcServer context in
5174 silcd/server_internal.h.
5176 * Fixed silc_server_packet_broadcast to send correct broadcast
5179 * The channel key is now distributed to the local client as soon
5180 as it is received from the router (in router environment) so that
5181 no other packet may be sent for the channel until client has
5184 * silc_server_remove_channel_user now broadcasts the received
5185 Remove Channel User packet if it is not broadcast packet already.
5186 The router must broadcast to inform other routers about removed
5189 * Added users field into SilcPacketContext that is a reference count
5190 of the context. One can increase the reference count by calling
5191 silc_packet_context_dup which is now changed to just increase the
5192 reference count instead of duplicating the data. The reference
5193 count is decresed by calling silc_packet_context_free that will
5194 free the data after the reference count hits zero.
5196 For now on the packet context and everything allocated into it
5197 (including the raw packet from network) must be freed by calling
5198 the new silc_packet_context_free function. Added also new function
5199 silc_packet_context_alloc that must be used now to allocate the
5200 context. This also means that if a routine is asynchronous from
5201 silc_[client/server]_packet_parse_type the packet context must
5202 be duplicated by calling silc_packet_context_dup. Otherwise it
5203 gets free'd after silc_[client/server]_packet_parse_type returns.
5204 Also, one must remember that if packet is duplicated then its
5205 reference count must be decresed by calling the free function as
5206 many times as it was duplicated.
5208 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5209 from both client and server.
5211 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Made joining to a channel working in router environment.
5215 * Cleaned up JOIN command on server side and create function
5216 silc_server_command_join_channel internal routine to make the
5219 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Changed silc_command_pending list to SilcDList. Also, added
5222 `ident' field to SilcServerCommandPending structure to identify
5223 the reply and to call correct callback.
5225 Added silc_server_command_pending_check function to replace the
5226 corresnponding macro. The silc_command_pending list is not
5229 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5230 to set identifier to previously allocated Command Payload. It
5231 is used to set identifier for command when resending Command
5234 * Added silc_command_payload_encode_payload to encode Command
5235 Payload buffer from SilcCommandPayload structure.
5237 * Added silc_argument_payload_encode_payload to encode Argument
5238 payload buffer from SilcArgumentPayload structure.
5240 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5242 * Changed WHOIS command to support router connection on server side.
5243 The whois request is always sent to router unless the server is
5244 standalone server. After server has received the reply from the
5245 router will it send the reply to the client.
5247 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5248 broadcast received broadcast packet. The function is used only
5249 by router. The broadcast packet is always sent to the router's
5252 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5253 render given ID to printable string, for log files for example.
5255 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Made basic router to router connections working. At least they
5258 can now connect to each other but nothing really works the way
5259 they are supposed - yet.
5261 * Added new initiator token to RouterConnection configuration
5262 file in silcd/serverconfig.[ch]. It is used to tell whether we
5263 are the initiator to the remote router or whether we'll expect
5264 the other end to connect.
5266 * Moved registering of listener task to silc_server_init, hence
5267 the server starts listenning as soon as it is run, even if it
5268 does not have connections to other routers. Let's see how well
5271 * Changed default connection retry timeouts for more suitable in
5274 * Removed cipher and such arguments from silc_idlist_add_client
5275 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5276 Added new function silc_idlist_add_data to add the keys and stuff
5279 * Added SilcIDListData structure and added it to SilcClientEntry
5280 and SilcServerEntry as their first field in the structure. This
5281 way we can explicitly cast the ID entries to the SilcIDListData
5282 structure and get common data for the entries. In past, we had
5283 to first check what type of connection it is and then cast it to
5284 correct ID entry type. Now, we can directly cast the opaque
5285 pointer to the SilcIDListData (no matter what ID entry it actually
5286 is) and get the data needed.
5288 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5291 in some circumstances even if threre were timeout tasks, though not
5292 IO tasks, but tasks anyway. Now fixed.
5294 * Defined SilcServerConnection structure to hold connection specific
5295 stuff about directly connected servers and routers. The definition
5296 is currently in silcd/server_internal.h. I thought about having
5297 a bit more important role fro this struct but for now it is used
5298 only when connecting to other server (or router actually).
5300 * Added connecting retry support in server when connecting to
5301 router(s). The retry feature implement exponential backoff
5302 algorithm. Also, added SilcServerParams structure to hold default
5303 parameters for server. For now, it include these retry settings
5304 and are hard coded. After server is moded to be as Silc Server
5305 Library this structure will be more important.
5307 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Changed client librarys channel->clients table to SilcList and
5310 changed code accordingly.
5312 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Changed client's channel table to SilcList and changed code
5315 accordingly. Also changed SilcChannelClientEntry to include back-
5316 pointer to the channel so that client entry can use that structure
5317 as list as well and we have fast cross-reference to the channel.
5318 This change dramatically decreased the complexity of channel
5319 handling with client entry and vice versa (removed one extra
5320 loop when searching for channel entry from many functions).
5322 * Changed server->sim from table to SilcDList and changed code
5325 * NAMES command can now be used from user interface. It will show
5326 the user list on the channel, neatly.
5328 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5329 Code now saves realname of the user if it becomes available.
5331 * Renamed configure.in to configure.in.pre and made ./prepare
5332 script to automatically add correct version string to
5333 configure.in which it creates from configure.in.pre.
5335 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * NAMES command reply now shows users mode with the nickname when
5340 * Moved silc_client_ch[u]mode[_char] functions from
5341 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5342 place sucks, they are utility functions and should be in some
5345 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5347 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5350 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Added TRQ (efficient deque and list library) into lib/trq. This is
5355 a very good list library that is currently used in the SILC. Defined
5356 SilcList API over the library because I didn't like the API very
5357 much. See lib/trq/silclist.h for the API and examples of how to
5358 use the API. Fixed various places in the code to use the new
5359 SilcList API. The SilcList is meant for lists that has a structure
5360 already defined as a list. It is not suitable to add just some
5361 context to the list (in TRQ, the context is the list actually).
5363 So, I defined SilcDList that can be used for the purpose where
5364 predefined list structure does not exit. This can be used as
5365 such list. Now some context just can be added to the SilcDList.
5366 Currently this list is not used in the SILC just yet, though there
5367 are a lot places where this can replace dynamically allocated
5368 tables and I will fix these places, later, to use SilcDList.
5369 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5370 and use TRQ internally).
5372 Also fixed some annoying warning messages that the original TRQ
5373 code generated. Also minor changes to TRQ's Makefile.in.
5375 * Added support for querying by Client ID to both WHOIS and
5376 IDENTIFY commands into server, as required by the protocol.
5378 * Removed method function pointers from SilcBuffer structure. They
5379 weren't used to anything and just increased the context size for
5380 no good reason. This change also made silc_buffer_alloc and
5381 silc_buffer_free functions inline functions.
5383 * Disabled command flooding detection support until it's fixed so
5384 that it accepts commands in but does not execute them more than once
5387 * Added silc_net_localhost(), to return local hostname, into
5388 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5389 that must be initialized before calling silc_client_init.
5391 * Added new function: silc_server_send_notify_on_channels to send
5392 notify messages to all channels client has joined. It is assured
5393 that the message is sent only once per client.
5395 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5396 lib/silcutil/silcutil.[ch] as silc_format function. The new
5397 function is generic and is used by server as well, not only by
5398 the logging routines.
5400 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5401 the provided version string was not acceptable. Added new function:
5402 silc_ske_check_version into lib/silcske/silcske.h. The function
5403 must be implemented by the application (client or server) and it
5404 does not reside in the SKE library. The function checks the version
5405 string remote end sent.
5407 * Added back pointers (to opaque context and to SilcSocketConnection)
5408 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5410 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5411 duplicate packet context structure.
5413 * Changed `notify' client operation to send same arguments as client
5414 receives from server except for ID's. ID's are mapped to correct
5415 ID entry and that is returned. Also, if channel entry is not sent
5416 by server but the notify is for channel the channel entry is sent
5417 to application (otherwise application doesn't know that it is for
5418 channel (library gets it from packet's Destination ID)).
5420 * Added silc_client_remove_from_channels into client library to
5421 remove a client from all channels it has joined to. Used when
5422 received SIGNOFF notify from server. Added also new function
5423 silc_client_replace_from_channels to replace old ID entry with
5424 new ID entry on all channels. Used when received NICK_CHANGE
5427 * Fixed ID Cache list handling in silc_idlist_get_client in
5428 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5429 to get (or query) client by ID.
5431 * Updated TODO list.
5433 * Added connection authentication status message defined by the
5434 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5435 support for these into the code in client and server side.
5437 * Added generic function silc_client_send_command to send any command
5438 with variable argument list. Application should use this function
5439 to send commands if the command functions provided by the library
5440 does not suite for the application's user interface needs.
5442 * Added new `failure' client operation. Application is notified about
5443 received failure packet if client is executing a protocol. In this
5444 case the protocol's execution has failed.
5446 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5447 is required by the protocol.
5449 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5450 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5453 * Added status flag to SilcSKE object to indicate realtime status
5454 of the SKE protocol.
5456 * Application receives now exactly same command reply arguments as
5457 the library receives from server. However, if ID is received the
5458 corresponding ID entry is returned to the application (eg. Client
5459 ID is mapped to correct SilcClientEntry entry and that is returned).
5460 Changed command_reply client operation due to this change.
5462 * Changed all ID's in commands and in command replys as ID Payloads.
5463 Change affected both client and server side codes.
5465 All ID's sent in SILC network (with execption of ID's in SILC
5466 Packet header) are sent in ID Payload to support variable length
5469 * Server now notifies nick changes and notifies all clients on
5470 the channels about the new nickname (about the new Client ID,
5473 * Implemented CMODE command to change channel modes. Supports all
5474 channel modes defined by the protocol specs except ban and invite
5475 lists. (Also, private channel key mode is supported but support for
5476 setting private channel key in client is missing, thus, this mode
5477 has no effect on client side (except that server requires that the
5478 client uses private channel key and normal channel traffic does not
5481 Also, invite mode works per se, but INVITE command does not work
5482 yet correctly, so you can set channel as invite only channel but
5483 inviting clients to the channel does not work (it is yet to be
5484 thought what's the best way to do it).
5486 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5487 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5488 Implemented CUMODE command to change user's mode on the channel.
5489 Supports all modes defined by the protocol specs.
5491 * Added NAMES command reply to return users modes on the channel.
5493 * Removed unnecessary and slow ciphers from lib/silccrypt.
5495 * Set SO_KEEPALIVE option to connection sockets by default.
5497 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5499 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5500 redefined the Notify Payload into protocol specs.
5502 * Added silc_id_payload_parse_id to get ID directly from raw
5505 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5508 accept searching by Client ID as well.
5510 * Added support for LEAVE and SIGNOFF notify types in client library.
5512 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5513 to parse ID Payload from raw data.
5515 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Added flags parameter into silc_ske_assemble_security_properties
5518 function in lib/silcske/silcske.[ch].
5520 * Changed notify client operation to fit better for notify messages
5521 sent by server. The notify payload received from server is now
5522 passed to the application (after parsing it to SilcNotifyPayload).
5523 It is application's responsibility to retrieve the arguments
5524 from the payload and show the message the way it wants. The message
5525 sent by server is implementation specific.
5527 * Changed public keys to comply with the protocol specification.
5528 Old public keys are not supported anymore and are not compatible.
5530 * Removed nickname from Channel Payload as the latest draft removed
5531 it. The client must resolve the nickname from the NAMES command
5532 reply received when it joined the channel.
5534 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5536 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Fixed some errors in protocol specification drafts.
5540 * Created lib/silccore/silcnotify.c to implement Notify Payload
5541 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5542 generic payloads described by protocol specifications. The file
5543 includes implementations for ID Payload and Argument Payload.
5545 * Changed Command Payload implementation to use the new Argument
5546 Payload. Changed command_xxxx_payload to command_payload_xxxx
5547 to comply with SILC coding conventions.
5549 * Added suppport for Argument Payload handling in Notify Payload
5550 implementation as protocol requires it. Added the new support
5551 into server and client lib as well.
5553 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added support for multiple nicknames on same channel. [n] is
5556 added locally to the nickname if there are more than one same
5557 nicknames on the channel.
5559 * Server now sends all nicknames that matched WHOIS request.
5560 Client also shows the list received from server.
5562 * Added TOPIC command to client side. User can now set and show
5563 current topic on channel.
5565 * Added MOTD command to client and server. Also, server sends the
5566 motd when client connects to the server.
5568 * Changed version strings to comply ISO 8601.
5570 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Fixed protocol error handling in client library. It should now
5573 cope even if the SKE fails for some reason.
5575 * Made new protocol specification drafts for submitting to IETF.
5577 * Implemented TOPIC command to server in silcd/command.c.
5579 * Added two new notify types into lib/silccore/silcnotify.h:
5580 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5581 notify nickname change and topic setting/change on a channel.
5583 * API change of command_reply operation in client library. The
5584 application gets now the status type received from server as well.
5586 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5590 * Cras fixed and optimized the packet handling even further and
5591 it should work now. Minor change to the prototype of function
5592 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5594 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Added new function into lib/silcutil/silcschedule.[ch]:
5597 silc_schedule_with_fd to select() a specified fd. The function
5598 returns after timeout expires or data arrives or goes. The
5599 function is used by packet routines to wait that all data is
5600 received from network.
5602 * Fixed data reading from network in lib/silccore/silcpacket.c.
5603 The code now assures that all data is read from the fd and then
5604 continues packet processing. This was a bug fix since the code
5605 used to drop some data in some circumstances.
5607 * Added new function into lib/silcclient/client.[ch]:
5608 silc_client_start_key_exchange to start key exchange after
5609 connection has been established to server. The code internally
5610 now uses this funtion but its main purpose was to provide it
5611 for applications that perform their own connecting. After
5612 application has created a connection it merely calls this
5613 function to start the key exchange between client and server.
5614 The library takes care of everything else after that.
5616 Updated also lib/silcclient/README to explain the usage of
5619 * Do not send to application information that connection has
5620 been established. Application gets notified it by connect
5623 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Applied cras's patch to add silc_schedule_one function. The
5626 function runs scheduler once and returns.
5628 * Fixed the scheduler after cras messed it up. The timeout
5629 handling works now as it's supposed to work.
5631 * Added into lib/silccore/ silcnotify.h to include notify
5632 message types support. Changed silc_server_send_notify*
5633 functions, in server.[ch], to support those new notify types.
5634 Added the support for the notify types into client library,
5635 as well. Added new notify client operation into ops.h in
5638 * Changed silc_server_packet_send_to_channel to send normal
5639 packets instead of just channel message packets. The function
5640 is now used to send the notify packets to channels. It is not
5641 used to send channel message packets anymore, as server never
5644 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5645 va_arg()s as it seems to require it nowadays. I guess, if SILC
5646 is compiled with older va_arg() the new code should work anyway.
5648 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Splitted core library. Core library (lib/silccore) includes
5651 now only SILC protocol specific core (and common) components.
5652 Created new utility library (lib/silcutil) that includes more
5653 generic purpose stuff. The stuff for util library was taken
5654 from the old core library. This was minor and easy split.
5656 * Created SILC Client Library (lib/silcclient) that includes
5657 implementation of the SILC client without user interface. This
5658 was major move from silc/ directory. The code has been changed
5659 so that it is transparent towards the user interface. The
5660 silc/ directory includes now the same user interface as before
5661 and it uses the new client library. Read lib/silcclient/README.
5662 Basicly, the client library performs everything else related
5663 to SILC except user interface handling. Also, configuration
5664 files are considered to be part of user interface and library
5665 does not handle them.
5667 This change also changed a lot of structures, function naming etc.
5668 Most important change was that SilcClientWindow object was
5669 renamed to SilcClientConnection in the client library. Created
5670 also new file lib/silcclient/ops.h. Also added new files
5671 silc/local_command.[ch] and silc/client_ops.[ch].
5673 All these changes were made to make it easier for user interface
5674 designers to create what ever user interface for the SILC client
5677 It is also expected that the server will be moved to lib
5678 directory as well and SILC Server Library will be created;
5679 sometimes in the future.
5681 * Removed Local commands from lib/silccore/silccommand.h as
5682 they are application specific and new client library does not
5683 handle any of those anymore.
5685 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5686 old client implementation in silc/.
5688 * Added support for callback functions in SILC_LOG_* macros.
5689 Application can now set its own callbacks that will be called
5690 instead of using the default functions that will always print
5691 the debug messages to stderr (or stdout). Also, debugging can
5692 now be disabled by setting silc_debug to FALSE and re-enabled by
5693 setting it to TRUE. Note, that logging will still work even
5694 if debugging is disabled.
5696 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5697 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5698 silc_log_reset_debug_callbacks.
5700 * To enable debugging in silc client one must give now -d
5701 option on command line.
5703 * Changed silc_schedule_init to automatically allocate task queues
5704 if they are not allocated before calling it.
5706 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Added GMP 3.1 into math library.
5710 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5713 a channel in SILC network. The packet is used by servers and
5714 routers to notify other routers that user has left a channel.
5715 This little feature was missing until now. Added the feature
5716 to protocol specification as well.
5718 Added functions: silc_server_send_remove_channel_user and
5719 silc_server_remove_channel_user into server.[ch].
5721 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5722 lib/silccore/silcpacket.h. However, they are not implemented
5725 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed joining to a channel and sending channel messages
5728 between server and router. The channel message sending should
5729 now work inside a cell.
5731 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Fixed the private message sending between server and router.
5734 The private message sending should now work inside a cell.
5736 * Added silc_server_replace_id into server.[ch] to replace
5737 existing ID in the SILC network.
5739 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5740 and silc_idlist_replace_server_id into idlist.[ch] in server.
5742 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Fixed the server to server connections. Server can again now
5745 connect to router. Router to router connections probably does
5748 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5750 * Added dynamic protocol registering support. Now protocols can
5751 registered and unregistered on the fly. Patch by cras.
5753 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Added lib/contrib directory to hold routines that some platforms
5756 don't have but are needed by SILC.
5758 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5759 into lin/contrib to provide getopt() and getopt_long() for
5760 those who don't have it.
5762 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Added AWAY command to client. When away message is set and
5765 client receives a private message packet the client automatically
5766 replies to the sender with the away message.
5768 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5769 bug seemed to be the cause of recent problems when compiling
5772 * Added version detection support to SKE protocol specification
5773 and added the new changes to the SKE implementation as well.
5774 There were other minor changes in the SKE protocol as well.
5776 Many changes in lib/silcske/silcske.[ch] and in
5777 lib/silcske/payload.[ch].
5779 * Added ^U functionality, clear input line. Patch from cras.
5781 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Mainly small bugfixes on core library. Fixed some debugging
5784 logging and buffer overflow in silclog.c.
5786 * Updated config.sub and config.guess on the distribution tree.
5788 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Added command lagging support in server. Client may execute
5791 commands now only once in two seconds.
5793 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Optimized packet reception. MAC computation and checking is now
5796 also more optimized. A lot previously duplicated code is now
5797 used as generic by both client and server.
5799 * Fixed key pair generation in clientutil.c
5801 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Added into lib/silccore/silcbufutil.[ch] new function;
5804 silc_buffer_realloc.
5806 * Moved generic packet sending/encryption functions to
5807 lib/silccore/silcpacket.[ch] from client and server. Some
5808 rewriting of the functions.
5810 * Moved all generic packet reception/decryption functions to
5811 lib/silccore/silcpacket.[ch] from client and server. The
5812 packet processing is now much cleaner in both client and server.
5813 These were major changes in both client and server.
5815 * Created many common functions in server to do packet sending.
5816 Previously code were duplicated a lot, this has been removed
5819 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Rewrote major parts of the ID cache system. Don't know
5822 whether it is better now or not but at least the API is more
5825 * Major rewrite on ID cache stuff on client because of the ID
5826 cache API changes. Added idlist.c to client.
5828 * Also major rewrite on ID cache stuff on server as well.
5829 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5830 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5831 in hand, instead they are all put into the ID cache system now.
5832 All server_idlist_* routines uses ID cache now instead of
5833 traversing its own lists (those lists does not exist anymore).
5834 SilcIDList though still exists. Also, SilcXXXEntry's are
5837 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Finally made the SKE implementation compliant to the protocol
5840 specification. All mp integers are now binary encoded as
5841 opposed being HEX encoded.
5843 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5846 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5847 functions: silc_[encode/decode]_pem. Also added function
5848 silc_encode_pem_file to PEM encode with newlines ('\n') for
5851 * SILC public keys are now encoded either PEM or binary. Same
5852 option is for private keys as well. By default private keys
5853 are binary encoded and public keys PEM encoded. Silly HEX
5854 encoding were removed.
5856 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5857 function to create fingerprints.
5859 * Fixed a bug in SHA1; does not change the original data anymore.
5861 * Partly implemented INFO command on client and server side.
5862 Fixed CLEAR command. Changes to SERVER command; show current
5863 server(s) when giving command without arguments. Added
5864 VERSION command to client.
5866 * Added check to server that unregistered connections cannot
5867 execute commands (unless it is specificly allowed).
5869 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Fixed screen refresh.
5873 * Fixed channel joining bug from client. On some circumstances
5874 client tried to join to a channel it had already joined.
5876 * Added public key verification process into client's protocol.c.
5877 The client now verifies the public key from user and saves
5878 it into ~./silc/serverkeys/ directory.
5880 Added into: clientutil.[ch]: silc_client_verify_server_key.
5882 * Changed SKE protocol's silc_ske_initiator_finish function
5883 to accept callback function that verifies the received public
5884 key. Removed old silc_ske_verify_public_key function.
5886 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5889 silc_pkcs_private_key[_data]_set.
5891 * Made the password and public authentication more cleaner in
5892 server's protocol.c.
5894 * Removed historic and obsolete protocol `channel_auth' from
5895 both client and server.
5897 * Removed wrong way of sending command status messages from
5898 server to client in server's command.c. The old way violated
5899 protocol specification.
5901 Changes to silccore/silccommand.[ch]: removed
5902 silc_command_encode_status_payload -> not needed anymore,
5903 changed silc_command_encode_payload_va to accept extra
5904 argument on variable argument list. The argument type must
5905 now be provided to the function. Also, added new function:
5906 silc_command_encode_reply_payload_va which is same as
5907 normal command_encode_payload_va except command status type
5908 is provided as extra argument.
5910 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Added ~./silc directory handling. The directory includes the
5913 public and private keys for the client.
5915 Added silc_client_check_silc_dir, silc_client_create_identifier
5916 and silc_client_load_keys.
5918 * Implemented SILC protocol compliant public key. Added public
5919 and private key saving to and loading from files.
5921 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5922 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5923 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5924 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5925 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5927 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5928 silc_pkcs_load_[public/private]_key.
5930 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Added silc_server_get_route (route.[ch]) to get connection
5933 data for the fastest route for given ID.
5935 * Implemented INVITE command on client and server. The command
5936 were re-defined in the SILC Protocol Specification and the
5937 implementation now complies with the specification.
5939 * Implemented PING command on client and server.
5941 * Implemented NAMES command on client and server. The server side
5942 supports currently only normal server not router server yet.
5943 Some changes to NAMES definition in SILC protocol specification.
5945 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Implemented LEAVE command on client and server.
5949 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
