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

64 channel is the same client that is giving the founder
65 mode to itself. It is done by comparing the saved public
66 key (it is saved even in the authentication is passphrase).
67 Affected file silcd/command.c.
69 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
71 * Do not process packet for disconnected socket connection.
72 Affected file lib/silccore/silcpacket.c.
74 * Process the DISCONNECT packet through scheduler in the
75 client library. Affected file lib/silcclient/client.c.
77 * Fixed the silc_client_packet_parse to not to increase
78 the packet sequence number if the conn->sock and the
79 current socket connection is not same. This can happen
80 for example during key agreement when the conn includes
81 multiple socket connections (listeners). Affected file
82 lib/silcclient/client.c.
84 * The sender of the file transfer request now provides also
85 the pointer (listener) for the key exchange protocol. If
86 the listener cannot be created then it sends empty key
87 agreement and lets the receiver provide the listener.
89 Added `local_ip' and `local_port' arguments to the
90 silc_client_file_send. If they are provided they are used,
91 if not then it will attempt to find local IP address, if
92 not found or bind fails then the remote client will provide
95 Affected files are lib/silcclient/client_ftp.c and
96 lib/silcclient/silcapi.h.
98 * Extended the FILE SEND command to support defining the
99 local IP and port for key exchange listener. They are

105 of the client's public key (if the proof of posession of the
106 corresponding private key is verified by the server).
107 Updated to the protocol specification.
109 * Added support of receiving the client's public key's
110 fingerprint in command reply in client library. Affected
111 file is lib/silcclient/command_reply.c, and
112 lib/silcclient/idlist.[ch].

170 during SERVER_SIGNOFF, but invalidate it. This way we
171 preserve the WHOWAS info for the client. Affected file
174 * Fixed SERVER_SIGNOFF notify handling in the server. The
175 server is now able to process incoming SERVER_SIGNOFF notify
176 for a server that it doesn't even know about. It will remove
177 the clients provided in the notify. Affected file
178 silcd/packet_receive.c.
180 * Check for partial packet in data queue after every packet that
181 was found from the queue. Return and wait for more data if
182 there is partial data in queue. Affected file is

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

260 Affected file lib/silcutil/silcnet.[ch].
262 * If key exchange or rekey protocol is active for a connection
263 parse all packets syncronously since there might be packets
264 in packet queue that we are not able to process without first
265 processing packets before them. Affected file silcd/server,
266 lib/silcclient/client.c.
268 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
269 whether library should continue processing the packet.

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

393 * Allow backup router to announce servers. All servers
394 announced by backup router are added to the global list
395 automatically. Update hte server's socket to our primary
396 router also when backup router announces a server.
397 Affected file silcd/packet_receive.c.
399 * Do not update the client->router in the function
400 silc_server_udpate_clients_by_server if the client is on
401 global list. We might fail to find any specific server
402 for locally connected clients and local cell clients. They
403 should still use the `from' and not `to' as client->router.
404 This fixes backup router resuming protocol. Affected file
407 * Decrease channel statistics count only if the channel
408 deletion worked. Affected files are silcd/server.c and

426 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Made better checks that the channel message is not sent
429 to the router it came from. Affected file is
430 silcd/packet_send.c. Fixed memory leak too.
432 * Announce informations for incoming router connection, but
433 only after checking if it is replaced by backup router.
434 Affected file silcd/packet_receive.c.
436 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

439 router environment. Affected file silcd/server_backup.c.
441 * Route packet only to one router in the function
442 silc_server_packet_send_to_channel. Affected file is
445 * Fixed silc_server_send_notify_dest to set the broadcast
446 flag. Fixed the silc_server_send_notify_topic to actually
447 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
448 Affected file silcd/packet_send.c.
450 * Changed the SFTP Filesystem interface. Changed the
451 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
452 the filesystem operation function. The SilcSFTPFilesystem
453 is now a context that is allocated by all filesystem allocation
454 functions and it already includes the operations structure
455 and filesystem specific context. It is given as argument
456 now to the silc_sftp_server_start. This made the interface
457 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
458 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
460 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
462 * Changed the backup router adding and getting interfaces
463 in the server. The router that will be replaced by the
464 specified backup router is now sent as argument. Affected

558 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
559 Affected file lib/silcutil/silcbuffer.h.
561 * Changed various routines in the core library to use the new
562 silc_buffer_set instead of allocating new buffer only for
565 * Added 64-bit value formatting and unformatting support to the
566 silc_buffer_[un]format routines. Affected file is
567 lib/silcutil/silcbuffmt.[ch].
569 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
570 to includes/bitmove.h.
572 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
574 * Fixed channel user mode saving in client library. Affected
575 file lib/silcclient/command[_reply].c.
577 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Defined the file transfer to the SILC Protocol. Added
580 new packet type SILC_PACKET_FTP and defined File Transfer
581 Payload. The mandatory file transfer protocol is SFTP
582 (SSH File Transfer Protocol). Affected file in addition
583 of the internet draft is lib/silccore/silcpacket.h.
585 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
586 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
587 is used as part of backup router protocol when the primary
588 router of the cell is back online and wishes to resume
589 the position as primary router.
591 * Redefined the MAC generation keys in the protocol. The
592 same key is not used anymore in both direction. Both
593 direction will now use different keys for sending and
594 receiving. This fixes a potential security flaw. This
595 change causes incompatibilities in the protocol.
597 * Redefined also the MAC computation from the packet.
598 An packet sequence number is now added to the MAC
599 computation. This prevents possible replay attacks against
600 the protocol. This change too causes incompatibilities
603 Added `sequence' field to the SilcPacketContext to hold
604 the current sequence number for the packet.
606 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
608 * Added `created' field to the SilcIDListData in the file
609 silcd/idlist.h to indicate the time when the entry was
612 * Added `created' field to the SilcChannelEntry too. Affected
615 * Added `creation_time' aguments to all the announcement functions
616 in the server. If it is provided then only the entries that
617 was created after the provided time frame are actually
618 announced. Affected file silcd/server.[ch].
620 * The protocol says that the Channel ID's IP address must be
621 based on the router's IP address. Added check for this in
622 the silc_server_new_channel when processing incoming New Channel
623 Payload. Affected file silcd/packet_receive.c.
625 * Print out the correct version with --version in SILC client.
626 Affected file irssi/src/silc/core/silc-core.c.
628 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
630 * Fixed WHOWAS command to check for completnes of the client
631 entry always, not just when the command is coming from client.
632 Affected file silcd/command.c.
634 * Added new function silc_server_packet_queue_purge to purge the
635 outgoing data queue to the network. After the function returns
636 it is guaranteed that the outgoing packet queue is empty.
637 Affected file silcd/packet_send.[ch].
639 * Purge the outgoing packet queue in the rekey protocol's final
640 callback to assure that all rekey packets go to the network
641 before quitting the protocol. Affected file silcd/server.c.
643 * Added silc_client_packet_queue_parse as similar function as
644 in server to the client library. The affected file is
645 lib/silcclient/client.c.
647 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
649 * Splitted silcd/server.c and created silcd/server_util.[ch]
650 for utility functions.
652 * Added new socket flag SILC_SF_DISABLED to indicate that the
653 connection is open but nothing can be sent to or received from
654 the connection. Affected file lib/silcutil/silsockconn.[ch].
655 The checking for disabled socket is checked in the low level
656 silc_socket_write and silc_socket_read functions.
658 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
660 * Allow only nicknames and channel names that fits into the
661 7-bit unsigned char ASCII set. Affected file silcd/command.c.
663 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
665 * When processing JOIN command reply in server check that if
666 the channel exists in our global list we'll move it the local
667 list. Affected file silcd/command_reply.c.
669 * Fixed the check whether client is joined on the channel already
670 in JOIN command. Affected file lib/silcclient/command.c.
672 * Fixed the JOIN command reply to check whether the channel
673 already exists. Affected file lib/silcclient/command_reply.c.
675 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
677 * Added silc_ske_status_string to map the SKE error numbers
678 to readable strings. The affected files are
679 lib/silcske/silcske[_status].[ch].
681 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
683 * Do not show the private channels on the WHOIS channel list
684 as it is not allowed by the protocol. The affected file is
687 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
689 * Assure that the packet length digged from the actual packet
690 is something sensible in the silc_packet_decrypt_rest_special
691 in lib/silccrypt/silcpacket.c.
693 * Free and NULL the allocated pointer in silc_hmac_alloc if
694 the HMAC allocation fails. The affected file is
695 lib/silccrypt/silchmac.c.
697 * Print the selected security properties to the log files in
698 the server. Affected file silcd/protocol.c.
700 * Add SKE's reference counter even if calling the completion
701 callback manually. Otherwise it goes negative, although it
702 does not cause any problems. The affected file is
703 lib/silcske/silcske.c.
705 * Remove the client entry with short timeout after giving the
706 KILL command. Affected file lib/silcclient/command.c.
708 * Fixed to send error reply in WHOIS and IDENTIFY commands in
709 case all found clients are already disconnected (WHOWAS would
710 found them) in the server. Affected file silcd/command.c.
712 * Update the last_receive (time of last data received) to be
713 updated only when received private or channel message so that
714 the idle time showed in WHOIS makes more sense.
716 * Added boolean field `valid' in to the SilcClientEntry in the
717 client library to indicate whether the entry is valid or not.
718 This fixes the nickname change bug on channel when changing
719 the nickname to be same than the old (like nick to Nick) the
720 nickname formatter doesn't set the new nick anymore to Nick@host.
721 Affected file lib/silcclient/idlist.[ch].
723 * Now actually fixed the nickname changing on disconnection.
724 Added new function silc_change_nick to the Irssi SILC Client.
725 Affected file irssi/src/silc/core/client_ops.c,
726 irssi/src/silc/core/silc-nicklist.[ch].
728 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
730 * Check that the public key exists in the GETKEY command before
731 trying to encode it. Affected file silcd/command.c.
733 * Print some notifications on received public keys with GETKEY
734 command in the Irssi SILC Client. Affected files are
735 irssi/src/fe-common/silc/module-formats.[ch],
736 irssi/src/silc/core/client_ops.c.
738 * Use IDENTIFY command to resolve the server information in the
739 GETKEY command instead of INFO command. Affected file
740 lib/silcclient/command.c.
742 * All command reply functions in the client library now calls
743 the pending command reply callbacks even if an error has
744 occurred. The server has done this a long time and now it was
745 time to move the client library to this as well. Now all
746 errors can be delivered back to the pending command reply
747 callbacks if necessary. Affected files are
748 lib/silcclient/command[_reply].[ch].
750 * Change the nickname on disconnection back to the username
751 because in reconnect the server will enforce it to it anyway.
752 Affected file irssi/src/silc/core/silc-servers.c.
754 * Fixed a config file parsing bug in the Irssi SILC client.
755 Affected file irssi/src/silc/core/clientconfig.c.
757 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
759 * When printing the channel mode on JOIN, verify that the
760 channel key and channel's HMAC are valid. Affected file
761 irssi/src/silc/core/client_ops.c.
763 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
765 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
766 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
767 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
769 * Removed channel key rekey task deleting from the function
770 silc_server_save_channel_key. Affected file silcd/server.c.
771 Added explicit timeout task context instead that is used to
772 delete the task if we are registering a new task before the
773 new task has elapsed.
775 * When channel key rekey occurs the client library now saves
776 the old channel key for a short period of time (10 seconds) and
777 is able to use it in case some is still sending channel
778 messages encrypted with the old key after the rekey. Affected
779 file lib/silcclient/[idlist.h|client_channel.c].
781 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
783 * Added check to the silc_server_new_id_real to not accept
784 new ID if it is the sender's own ID. Affected file is
785 silcd/packet_receive.c.
787 * Assure that we do not announce ourself or the one we've
788 sending our announcements when we're router and are announcing
789 servers to our primary router. Affected file silcd/server.c.
791 * Fixed silc_server_command_identify_check_client to assemble
792 correct WHOIS packet. It send corrupted WHOIS packet and
793 caused problem with router to router connections. Affected
794 file silcd/command.c.
796 Fixed also silc_server_command_whois_check the same way
797 as for the IDENTIFY command.
799 * Added new SilcIDListStatus to the server in the SilcIDListData
800 structure. The status now includes the current status of
801 the entry (like registered, resolved etc.). Affected file
802 silcd/idlist.[ch]. Defined a bunch of different status types
803 as well. This replaced the old boolean registered field as well.
805 Added resolve_cmd_ident field to the SilcClientEntry structure
806 too so that if the entry is for example being resolved so
807 another command may attach to the same pending command reply
808 without requiring to resolve the same entry again. This concept
809 should optimize the WHOIS and the IDENTIFY resolving under
810 heavy load by taking away unnecessary resolving for entries
811 that are being resolved already.
813 Added support for adding multiple pending commands for one
814 command idenfier. Affected file silcd/command[_reply].[ch].
816 * Fixed WHOIS and IDENTIFY save to remove the cache entry
817 before deleting the data. Otherwise the hash table will have
818 freed data in comparison functions. Affected file is
819 silcd/command_reply.c.
821 * Fixed silc_idlist_replace_client_id to add the new entry to
822 the cache with NULL nickname. Otherwise there will be invalid
823 memory as the nickname after the nickname is freed. Affected
824 file silcd/packet_receive.c.
826 * Fixed the silc_idlist_get_clients_by_hash. The entries was
827 saved into wrong slots because the previous number of entries
828 was not taken into account. Affected file silcd/idlist.c.
829 Fixed same thing in silc_idlist_get_clients_by_nickname too.
831 * If we are router and we receive JOIN notify to a channel that
832 does not have any users then notified client is marked as the
833 channel founder, as it is it. The affected file is
834 silcd/packet_receive.c
836 * Added to the extended hash table API's table_del_*ext functions
837 the destructor as argument too, so that the caller can decide
838 which destructor to use or whether to use destructor at all.
839 Affected file lib/silcutil/silchashtable.[ch].
841 * Fixed ID Cache purging. It actually deleted the entries from
842 the hash table after the data was freed. The hash table ended
843 up comparing freed memory. The affected file is
844 lib/silccore/silcidcache.c.
846 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Fixed Irssi SILC client's KILL command's HELP syntax.
850 * The USERS command now resolves the detailed user information
851 if the userinfo field is missing. Affected file is
852 lib/silcclient/command_reply.c.
854 * Do not print error in silc_file_read if the read file does
855 not exist. Just silently return NULL. Affected file is
856 lib/silcutil/silcutil.c.
858 * Fixed the silc_log_output to not wine about NULL filename
859 and to not create some bogus " " filename. Affected file is
860 lib/silcutil/silclog.c.
862 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
864 * Fixed various printing bugs on the user interface in the
865 Irssi SILC Client. Minor changes that were forgotten from
868 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Fixed the configure.in.pre and the compilation and distribution
871 environment to support the new autoconf 2.52. That version is
872 now required to compile the CVS trunk.
874 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
876 * Renamed function silc_parse_nickname to silc_parse_userfqdn
877 to generally parse user@fqdn format strings. Affected file
878 lib/silcutil/silcutil.c.
880 * Added nickname_format and nickname_force_format fields to the
881 SilcClientParams structure. The first one defines the format
882 for the nicknames that the library will enforce if the receives
883 multiple same nicknames. The second one is boolean value and
884 can be used to force the library to always enforce the format
885 to the nicknames regardles whether there are multiple nicknames
886 or not. This configurable formatting was employed to flexibly
887 support accessing multiple nicknames from the user interface.
888 The userinterface can now set the nicknames to what ever format
889 they prefer. Affected file lib/silcclient/silcapi.h.
891 Added function silc_client_nickname_format to the file
892 lib/silcclient/idlist.c. It performs the nickname formatting.
894 Added new field `hostname´ to the SilcClientEntry context.
895 It holds the hostname of the client. Affected file is
896 lib/silcclient/idlist.h.
898 * Irssi SILC Client sets the nicknames in nick@hostn format.
899 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
900 irssi/src/silc/core/silc-core.c.
902 The WHOIS printing now also shows both the real nickname and
903 the formatted nickname so that user knows how to access the
904 user if there are multiple same nicknames cached. Affected
905 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
906 printing formatting too to take the hostname now as a separate
907 argument. The Affected file is
908 irssi/src/fe-common/silc/modules-formats.[ch].
910 * Changed the silc_client_get_clients_local to accept the formatted
911 nickname as argument. It accepts the real nickname too but the
912 formatted nickname can be used to find the true entry from
913 multiple entries. Affected file lib/silcclient/silcapi.h and
914 lib/silcclient/idlist.c.
916 * Added nickname_format_parse field to the SilcClientParams.
917 It is a callback function provided by the application to parse
918 the nickname out of the formatted nickname string. The library
919 calls it to get the nickname from the formatted string. Since
920 the application generally knows better the format of the nickname
921 string it parses it instead of the library, even though library
922 encodes the formatted string. If the callback function is not
923 provided then the library will use the string as is. The
924 affected file is lib/silcclient/silcapi.h.
926 * All the nickname strings passed to the client library in
927 commands are now expected to be formatted nickname strings.
928 If the command does not support the formatted nickname string
929 it will assume that the sent string is the actual nickname.
930 Affected file lib/silcclient/command.c.
932 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
934 * Added public key authentication support to OPER and SILCOPER
935 commands in the client library. Affected file is
936 lib/silcclient/command.c.
938 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
940 * Changed the get_auth_methdod client operation to be asynchronous.
941 It can be async if the application resolves the authentication
942 method from the server during the negotiation. Added new
943 SilcGetAuthMeth completion callback that the application will
944 call after resolving the authentication method.
946 Added function silc_client_request_authentication_method that
947 the application can use to resolve the authentication method
948 from the server. Added also SilcConnectionAuthRequest callback
949 that the library will call after the server has replied. The
950 application can call this function if it does not know the
951 current authentication method.
953 Affected files are lib/silcclient/client.c and
954 lib/silcclient/silcapi.h.
956 * The Irssi SILC client now automatically resolves the authentication
957 method incase any configuration information is not present (and
958 currently there never is). The affected file is
959 irssi/src/silc/core/client_ops.c.
961 * Fixed public key authentication from the client library.
962 Affected file lib/silcclient/protocol.c. Changed also the
963 protocol specification about the public key authentication in
964 the connection authentication protocol. The actual data to be
965 signed is now computed with a hash function before signing.
967 * Fixed the public key authentication from the server as well.
968 Affected file silcd/protocol.c.
970 * Removed the mlock()'s from the memory allocation routines.
971 Affected file lib/silcutil/silcmemory.c. The ./configure does
972 not check anymore for the mlock(). Affected file is
975 * Fixed USERS command in server to allow the execution of the
976 command for private and secret channels if the client sending
977 the command is on the channel. Affected file silcd/command.c.
979 * Fixed silc_client_get_clients_local to return the clients
980 count correctly. It could return wrong value. Affected file
981 lib/silcclient/idlist.c.
983 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
985 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
986 types. The assembler optimizations seemed not to like 64-bit
987 data types. The assmebler optimizations thus are now enabled
988 also for BSD systems as opposed to only enable them for Linux.
990 * Do not check for threads at all on BSD systems. Affected
991 file configure.in.pre.
993 * Removed -n and -h options from the Irssi SILC Client since
994 they are not used in silc.
996 * Fixed the prime generation to assure that the first digit
997 of the generated random number is not zero since our conversion
998 routines does not like number strings that starts with zero
999 digit. If zero digit is seen the random number is regenerated.
1000 This caused some corrupted RSA keys when the zero first digit
1001 was met. Affected file lib/silcmath/silcprimegen.c.
1003 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1005 * Fixed WIN32 configuration in the ./configure script.
1006 Fixed to include xti.h on environments that has it.
1007 Patches by Carsten Ilchmann and andrew.
1009 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1011 * Changed the silc_id_create_client_id to be collision
1012 resistant. It is now assured that there cannot be created
1013 two same client ID's. I suspect that some weird bugs in
1014 the server were actually caused by duplicate Client IDs.
1015 Affected file silcd/serverid.[ch]. A router receiving
1016 new ID now also assures and informs the sending server
1017 if the ID caused collision.
1019 * Changed the silc_id_create_channel_id to also assure that
1020 there are no collisions.
1022 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1024 * Statement about ignoring the Mutual Authentication flag when
1025 performing rekey with PFS was a bit misleading. It is ignored
1026 if it was set in the initial negotiation, it cannot be even
1027 set in the rekey. Fixed in the ke-auth draft. Started the
1028 new versions of the protocol drafts in the doc/.
1030 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1032 * Fixed a bug in silc_client_command_identify_save when saving
1033 new channel information. The channel name was no duplicated
1034 and caused crash on exit. Affected file is
1035 lib/silcclient/command_reply.c.
1037 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1039 * Fixed the getkey command handling in the server. Send just
1040 empty OK reply to the sender if the key could not be fetched
1041 (but everything else was ok, like the key just was not available).
1042 Changed the public key parameter to optional in the protocol
1043 specs so that empty OK reply can be sent. Affected file
1046 Added a message to Irssi SILC client to tell to user if the
1047 server did not return a public key.
1049 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1051 * Fixed a channel key regeneration bug. It registered new
1052 timeout tasks exponentially until all system resources were
1053 used. Affected file silcd/server.c.
1055 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1057 * Added the SILC Document generator to the scripts/silcdoc.
1058 It can be used to generate the Toolkit Reference Manual out
1059 of the source tree. Internally it will also use the RoboDoc
1060 generator now imported in util/robodoc.
1062 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1064 * Added couple of return's in rekey protocol if error orccurred
1065 during the protocol. The execution must be terminated.
1066 Affected file silcd/protocol.c. Also, terminate the protocol
1067 always with timeout.
1069 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1071 * The client's Client ID was created initally from the wrong
1072 nickname (it could have been in format nick@host) in the
1073 silc_server_new_client. Affected file silcd/packet_receive.c
1075 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1077 * Added some SILC_LOG_ERROR's to various error conditions
1078 if client could not be added to ID cache. Affected files
1079 silcd/packet_receive.c and silcd/server.c.
1081 * When client's sock->user_data is freed, NULL also the
1082 client->router and client->connection pointers. Added check
1083 for these pointers being NULL to various places around the
1084 code. Affected file silcd/server.c.
1086 * Added client->data.registered == TRUE checks to various
1087 places around the code to assure that unregistered client's
1088 are not handled when it is not allowed. Affected file
1091 * Added `bool registered' fields to all
1092 silc_idlist_[server|client]_get_* routines to indicate whether
1093 the fetched client needs to be registered or not. Affected
1094 file silcd/idlist.[ch].
1096 * Add your own entry as registered to the ID cache in the
1097 server. Affected file server.c.
1099 * Fixed a bug in silc_server_new_server. The SilcServer was
1100 set as the new server's context instead of SilcServerEntry.
1101 This naturally caused some weird bugs.
1103 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1105 * Do not delete the channel rekey task when adding it
1106 for in silc_server_create_channel_key.
1108 * Changed the silc_server_create_channel_key to return
1109 TRUE or FALSE to indicate the success of the channel key
1112 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1114 * Fixed MSVC++ project files and added missing files to

1120 does not have it defined. Affected files are
1121 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1123 * Fixed buffer overflow from Irssi SILC Client. Affected
1124 file irssi/src/fe-common/core/themes.c.
1126 * Fixed double free in client library in the file
1127 lib/silcclient/client.c when disconnecting from server.
1129 * Applied double free patch from cras to Irssi SILC client.
1130 Affected files irssi/src/core/[modules/expandos].c
1132 * Fixed the disconnection handling to Irssi SILC Client.
1133 The application must call silc_client_close_connection
1134 in ops->connect client operation in case of failure of
1135 the connection. Affected file is
1136 irssi/src/silc/core/client_ops.c.
1138 * Do not set sock->protocol to NULL in the function
1139 silc_client_close_connection after executing the protocol's
1140 final callback since the sock might not be valid anymore.
1141 Affected file lib/silcclient/client.c.
1143 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1145 * Do not enable SILC_THREADS if the linking with libpthread
1146 did not happen. Affected file configure.in.pre.
1148 * Added notion to protocol specification that server must
1149 verify the sent authentication payload with CMODE when
1150 setting the channel founder key. Implemented it to the
1151 server. Affected file silcd/command.c.
1153 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1155 * Added _EXTRA_DIST SILC distribution variable to the
1156 distributions file. It is used to conditionally add extra
1157 files or directories to the specific distribution. Affected
1158 files ./prepare, Makefile.am.pre and distributions.
1160 Removed the `_' from the start of the distribution names.
1163 * Added README.WIN32 for instructions to compile the Toolkit
1166 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1168 * Fixed a double free in disconnection in the server. Affected
1169 file is silcd/server.c.
1171 * Fixed the lib/silcske/groups.c to work now also with GMP
1172 MP library. The string conversion did not work when using
1173 specific base and the base is indicated in the string as well.
1175 * Created win32/ directory which now includes MSVC++ specific
1176 stuff so that toolkit (DLLs) may be compiled with MSVC++.
1177 It will appear only in the toolkit distribution
1179 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1181 * Changed the key material distribution function in case when
1182 the hash output is too short. The data is now concatenated
1183 a bit differently than it used to. Made the change to the
1184 SKE protocol specification.
1186 * Added better GMP detection to configure.in.pre. A patch
1189 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1191 * Fixed a minor bug in SKE that might cause some problem on
1192 some platforms. Affected file lib/silcske/silcske.c.
1194 * Added the cookie checking for initiator in the SKE. It checks
1195 that the responder returns the sent cookie unmodified. The
1196 affected file is lib/silcske/silcske.c. Added new SKE
1197 error type INVALID_COOKIE that can be sent during the
1198 negotiation. Fixed some memory leaks as well.
1200 * Added the "invalid cookie" error message to Irssi SILC client's
1203 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Added `task_max' field to the SilcClientParams to indicate
1206 the maximum tasks the scheduler can handle. If set to zero,
1207 default values are used. Affected file lib/silcclient/silcapi.h.
1209 * Fixed memory leaks in silc_client_close_connection. Affected
1210 file lib/silcclient/client.c.
1212 * Added silc_client_del_client_entry to client library to free
1213 all memory of given client entry. Affected file is
1214 lib/silcclient/idlist.[ch].
1216 * Added new functions silc_client_del_channel and
1217 silc_client_del_server to delete channel and server entries.
1218 Affected file lib/silcclient/[silcapi.h/idlist.c].
1220 * Removed silc_client_del_client_by_id from silcapi.h.
1222 * Fixed the INFO command to return the server's own info
1223 correctly when querying by Server ID. Affected file is
1226 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Removed the non-blocking settings in WIN32 code in the
1229 silc_sock_[read/write] and added SleepEx instead. Affected
1230 file lib/silcutil/win32/silcwin32sockconn.c. The availability
1231 of input data is now checked with FIONREAD and ioctlsocket.
1233 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Call silc_schedule_task_del_by_context in the
1236 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
1237 Affected file lib/silccore/silcprotocol.c.
1239 * Call silc_protocol_cancel for active protocols in the
1240 silc_server_close_connection if the funtion
1241 silc_server_free_sock_user_data has not been called.
1242 Affected file silcd/server.c.
1244 * Generic tasks cannot be deleted using the del_by_fd
1245 task deleting function since generic tasks does not match
1246 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
1248 * Added a notion to SILCOPER help file that the SILCOPER works
1249 only on router server, not on normal server.
1251 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1253 * Added for WIN32 support for the new scheduler as well.
1254 Affected file lib/silcutil/win32/silcwin32schedule.c.
1256 * Fixed the SHA1 implementation to work on various platforms.
1258 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
1261 API. It is part of the scheduler now. Everything else is
1262 as previously but some functions has changed their names.
1263 Checkout the lib/silcutil/silcschedule.h for the interface.
1264 Updated all applications to use the new interface. Affected
1265 files are lib/silcutil/silcschedule.[ch].
1267 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1269 * Found a bug in the SKE implementation. The HASH value,
1270 specified by the protocol, was not computed correctly. The
1271 public key of the responder was not added to the computation
1272 even though it is mandatory. Affected file lib/silcske/silcske.c.
1273 This unfortunately causes incompatibilities with older
1274 clients and servers.
1276 * Added WIN32 specific network init and uninit functions:
1277 silc_net_win32_init and silc_net_win32_uninit to init and uninit
1278 the Winsock2. Affected file lib/silcutil/silcnet.h and
1279 lib/silcutil/win32/silcwin32net.c.
1281 * Set the socket always to nonblocking mode on WIN32 after
1282 reading data or writing data. Affected file is
1283 lib/silcutil/win32/silcwin32sockconn.c.
1285 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1287 * Fixed various compilation problems under WIN32. Affected
1288 files lib/silcutil/win32/silcwin32thread.c and
1289 lib/silcutil/win32/silcwin32schedule.c.
1291 * Removed all _internal.h #includes from public header
1292 files. Internal headers must never be included from
1295 Removed also the lib/silcske/payload_internal.h file.
1297 * All include files that may be needed (public and some others
1298 included by the public headers) by application developers are
1299 now copied to the ./includes directory. It does not copy any
1300 internal headers. Affected file Makefile.defines.pre and all
1301 Makefile.am's under lib/ and subdirs.
1303 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1305 * Do not change the ~/.silc directory's permissions automatically.
1306 Affected file irssi/src/silc/core/clientutil.c.
1308 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Do not cancel the protocol in silc_server_close_connection
1311 it might cause recursion. Now cancelled in the function
1312 silc_server_free_sock_user_data. Affected file silcd/server.c.
1314 * Fixed the silc_server_remove_clients_by_server to regenerate
1315 the channel keys correctly finally. Added also new function
1316 silc_server_remove_clients_channels to actually do it.
1317 Affected file silcd/server.c.
1319 * Fixed the silc_server_new_channel to not crash by giving
1320 wrong router to the new channel. Affected file is
1321 silcd/packet_receive.c.
1323 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1325 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
1326 which is given as argument to the silc_client_alloc now.
1327 It can be used to configure the client and set various parameters
1328 that affect the function of the client.
1330 * The USERS command in server did not check whether the channel
1331 is private or secret. Affected file silcd/command.c.
1333 * Added new argument to the USERS command in protocol specification.
1334 The USERS command now can take the channel name as argument
1335 as well. Added support for this in client and server and
1336 updated the protocol specs.
1338 * Completed the GETKEY command in client. It can be now used
1339 to fetch also servers public key not only some clients.
1340 Affected files lib/silcclient/command[_reply].c.
1342 * Added silc_client_get_server to return server entry by the
1343 server name. Affected files lib/silcclient/silcapi.h and
1346 * Redefined the IDENTIFY command in protocol specification to be
1347 more generic. It now can be used to query information about
1348 any entity in the SILC Network, including clients, servers and
1349 channels. The query may be based either the entity's name
1350 or the ID. Added support for this in both client and server.
1352 Affected files silcd/command.c and lib/silcclient/command.c
1353 and command_reply.c.
1355 * Optimized the WHOIS and WHOWAS commands in the server. Removed
1356 the _from_client and _from_server functions. Affected file
1359 * Added silc_client_get_channel_by_id_resolve to the file
1360 lib/silcclient/silcapi.h to resolve channel information by
1361 its ID. Added also silc_client_get_channel_by_id that
1362 does not resolve it from the server.
1364 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1366 * Added SilcServerEntry context into the client library
1367 to represent one server. The INFO command now allocates
1368 these to save the resolved server info. For now on the
1369 client library will also keep information about servers,
1370 connected and resolved with INFO.
1372 The INFO command now allocates the SilcServerEntry context
1373 and saves the server info there. The COMMAND_REPLY in
1374 the INFO now returns the parameters to application in
1375 same order as defined in the protocol specification.
1377 The entries are cached in the client->server_cache.
1379 * The INFO command is now issued after received the Client ID
1380 from the server. Affected file lib/silcclient/client.c.
1382 * The CMODE_CHANGE notify may now return also an SilcServerEntry
1383 to the application as the mode changer might be server.
1384 It is guaranteed that NULL is not returned anymore to the
1385 application. Affected file lib/silcclient/client_notify.c.
1387 The ID Type is now also passed to the application so that
1388 it can check whether the returned entry is SilcClientEntry
1391 Added new function silc_client_get_server_by_id to return
1392 the server entry by ID. Affected files are the
1393 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
1395 * Do not create the channel in the Irssi SILC Client when issuing
1396 the JOIN command but when received the sucessful JOIN command
1397 reply. Otherwise the channel might get created even though we
1398 could not join it. The Affected file is
1399 irssi/src/silc/core/[silc-channels.c/client_ops.c].
1401 * Fixed a channel joining bug in router. The router must also
1402 check the channel modes, invite and ban lists etc. when serving
1403 the JOIN command sent by normal server. Affected file is
1404 silcd/command.c. The router now resolves the client's
1405 information from the server who sent the JOIN command if it
1406 does not know it, and processes the JOIN command only after
1409 * Changed the SilcCommandCb to take new argument; void *context2.
1410 Affected file lib/silccore/silccommand.h
1412 The second argument in the command callbacks in the server now
1413 includes the SilcServerCommandReplyContext if the command was
1414 called as pending command callback from the command reply.
1415 Otherwise it is NULL. When called as pending the status of the
1416 command reply will be checked and if it was erronous the
1417 error will be sent to the original sender of the command.
1418 This way the client always receives the error messages even
1419 though the server was actually the one who received the error
1420 when it resent the command to router, for example. Affected
1421 files silcd/command[_reply].[ch].
1423 * Fixed sending WHOWAS command's error message to client if
1424 the requested client could not be found. It was missing.
1427 * Changed the CMODE and CUMODE commands reply arguments in the
1428 protocol specification. The Channel ID is now sent in both
1429 of the commands to identify the channel. Implemented this
1430 new feature to the client and server. Affected files
1431 lib/silcclient/command_reply.c and silcd/command.c.
1433 * Made better checks for invite and ban lists in the JOIN
1434 command in server. Affected file silcd/command.c.
1436 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * The server now performs the incoming host IP/DNS lookup
1439 using the silc_socket_host_lookup and thus does not block
1440 the server anymore. Affected file silcd/server.c.
1442 * Completed the multi-thread support for SILC Scheduler in
1443 the lib/silcutil/silcschedule.c.
1445 * Fixed the configure.in.pre to detect the pthread correctly
1448 * Fixed a deadlock in silc_task_queue_wakeup in the file
1449 lib/silcutil/silctask.c.
1451 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1453 * Added new function silc_schedule_wakeup that is used in
1454 multi-threaded environment to wakeup the main thread's
1455 schduler. It needs to be used when a thread adds a new task
1456 or removes a task from task queues. After waking up, the
1457 scheduler will detect the task queue changes. If threads
1458 support is not compiled in this function has no effect.
1459 Implemented the wakeup mechanism to both Unix and WIN32
1460 systems. Affected files are lib/silcutil/silcschedule.[ch],
1461 lib/silcutil/unix/silcunixschedule.c and the
1462 lib/silcutil/win32/silcwin32schedule.c.
1464 * Added new function silc_task_queue_wakeup to wakeup the
1465 scheduler by the specified task queue. Affected file
1466 lib/silcutil/silctask.[ch].
1468 * The silc_socket_host_lookup_start now wakes up the scheduler
1469 after adding the timeout task. Affected file is
1470 lib/silcutil/silcsockconn.c.
1472 * The silc_socket_host_lookup is synchronous now if the threads
1473 support is not compiled in. However, the callback is still
1474 called asyncronously through the scheduler, anyway. Affected
1475 file lib/silcutil/silcsockconn.c.
1477 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1479 * Added new function silc_socket_host_lookup to perform
1480 asynchronous IP and FQDN lookups for the socket connection.
1481 Affected files lib/silcutil/silcsockconn.[ch].
1483 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1485 * Added SILC_MUTEX_DEFINE to define the mutex on environments
1486 that may or may not compile the mutex support in.
1488 Changed the silc_mutex_alloc interface. It allocates the
1489 mutex now to the sent pointer and returns TRUE or FALSE.
1491 Affected file lib/silcutil/silcmutex.h.
1493 * Wrote the SILC Task Queue interface to support multi-threads.
1494 Affected file lib/silcutil/silctask.[ch].
1496 * Wrote the SILC Scheduler to support multi-threads. Affected
1497 file lib/silcutil/silcschedule.c.
1499 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Implemented the SILC Mutex API and SILC Thread API for WIN32
1502 in lib/silcutil/win32/.
1504 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1506 * Defined SILC Mutex API and SILC Thread API and implemented
1507 them for Unix. Affected files are
1508 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
1509 lib/silcutil/unix/silcunixmutex.c and
1510 lib/silcutil/unix/silcunixthread.c.
1512 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1514 * Fixed the silc_server_remove_clients_by_server's channel
1515 key re-generation. The hash table handling was incorrect
1516 and would not work with many channels. Affected file is
1519 * Fixed some memory leaks around the server code.
1521 * Rewrote the silc_server_get_users_on_channel to support IPv6
1522 based Client ID's. Affected file silcd/server.c.
1524 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
1525 specification. However, a separate document must be written
1526 to define the detailed signing procedure and the payload
1527 associated with the flag. Defined the flag to the
1528 lib/silccore/silcchannel.h as well.
1530 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1532 * Changed the dynamic tables to static size tables in the
1533 lib/silccrypt/silchmac.c.
1535 * Removed GCC dependencies from the code. A patch by cras.
1537 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1539 * Do not show the error "Error receiving packet bla bla"
1540 in server if it really was not an error (-2 means that reading
1541 is pending). Affected file silcd/server.c.
1543 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Fixed a possible crash in silc_server_remove_clients_by_server
1546 in silcd/server.c. Fixed there also some memory leaks.
1548 * Fixed the silc_idlist_replace_client_id. It could replace
1549 wrong key in the hash table. Affected file silcd/idlist.c.
1551 * Do not check whether there are global users on the channel
1552 if the channel->global_users is FALSE. Affected functions
1553 silc_server_remove_from_one_channel and
1554 silc_server_remove_from_channels in silcd/server.c. Also,
1555 do not check if the removed client is local as we can be
1556 sure that global client was not removed from the channel
1557 and checking for global users is not needed.
1559 * The silc_server_remove_clients_by_server now re-generates
1560 the channel keys correctly for those channels that had
1561 clients removed from them. Affected file silcd/server.c.
1563 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Found the reason of random crashes in the server. We weren't
1566 ignoring the SIGPIPE signal (which can be sent in write())
1567 and it crashed the server. Affected file silcd/silcd.c.
1569 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Assure that sock->user_data is not NULL in the function
1572 silc_server_packet_send in silcd/packet_send.c.
1574 * Disconnect the remote connection if it could not be added
1575 to any ID lists in the server. The affected file is
1578 * Check in silc_server_packet_send[_real/dest] that the
1579 socket is not disconnecting and ignore the data if it is.
1580 Affected file silcd/packet_send.c.
1582 * Define inline to __inline on native WIN32 compilation.
1583 Affected file includes/silcwin32.h.
1585 * Added some explicit type casts for inline code since MSVC
1586 require them. Affected files lib/silcutil/silcbuffer.h,
1587 lib/trq/silcdlist.h and lib/trq/silclist.h.
1589 * Print warning in log files from now on if the packet
1590 decryption fails. Affected file silcd/server.c.
1592 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1594 * Changed the `say' client operation's interface to accept
1595 new `type' argument to indicate the type of the message sent
1596 by the library. The application may filter the library's
1597 messages according the type. The affected file is the
1598 lib/silcclient/silcapi.h.
1600 * Added two new functions to lib/silcclient/silcapi.h:
1601 silc_client_del_client and silc_client_del_client_by_id.
1602 Affected file lib/silcclient/idlist.c.
1604 * Moved the clientincludes.h from includes/ to silc/ and
1605 serverincludes.h from includes/ to silcd/.
1607 * The modes for the CMODE and CUMODE are now passed as
1608 uint32 for application with COMMAND_REPLY. The affected
1609 file is lib/silcclient/command_reply.c.
1611 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1613 * /WHOIS without arguments shows client's own information.
1614 Affected file lib/silcclient/command.c.
1616 * Changed PING to not accept any arguments. The specs
1617 says that client can ping only the connected server so
1618 requiring an argument is not needed. Affected file is
1619 lib/silcclient/command.c.
1621 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Fixed a fatal bug in private message sending and reception
1624 encryption and decryption when using private message keys.
1625 The implementation was incorrect and did not follow the
1626 specification. It causd that some of the message were
1627 lost since it did not use the sending and receiving keys
1628 as the protocol suggests. This has been fixed and will cause
1629 incompatibilities with older clients when sending private
1630 message encrypted with private message keys. Affected files
1631 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
1632 and various other in Irssi SILC Client.
1634 Added `responder' boolean argument to the functions
1635 silc_client_add_private_message_key[_ske] to indicate when
1636 the key is added as responder or initiator of the key
1639 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Removed the silc_ske_check_version function and created
1642 a SilcSKECheckVersion callback. Added also a function
1643 silc_ske_set_callbacks that is now used to set all SKE
1644 callbacks. The callback functions are not given to
1645 the SKE functions anymore, but this function is used to
1648 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
1650 * Added `silc_version' argument to the silc_client_alloc
1651 to define the version of the application for the library.
1652 The library will use the version string to compare it
1653 against the remote host's (usually a server) version
1654 string. Affected file lib/silcclient/silcapi.h
1656 * Added the KE protocol context to Key Agreement context
1657 in client library so that we can abort the SKE if it
1658 is in process when we get timeout. Affected file is
1659 lib/silcclient/client_keyagr.c.
1661 * Do not resolve the client ID forever if it returns in the
1662 first time that such client does not exist. This was done
1663 for example with private message. Affected file is
1664 lib/silcclient/client_prvmsg.c.
1666 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1668 * Do not add regex.h for WIN32. The affected file
1669 includes/silcincludes.h.
1671 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
1672 not work yet 100%. It generates the DLL's automatically
1673 when compiling with --with-win32 under cygwin.
1675 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1677 * lib/contrib/regex.c is not compiled on WIN32.
1679 * Added silc_net_get_socket_opt function to the
1680 lib/silcutil/silcnet.h.
1682 * Added includes/silcwin32.h for WIN32 specific includes
1685 * Do not use ptime structure or any of the posix process
1686 functions on WIN32 in lib/silccrypt/silrng.c.
1688 * Added silc_gettimeofday to provide generic function
1689 for struct timeval on all platforms. Added the function
1690 to lib/silcutil/silcutil.h.
1692 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1695 library as they clearly belong there. As a plus side we
1696 can make the actual socket connection routines platform
1699 Added also new generic function silc_socket_read and
1700 silc_socket_write (that used to be silc_packet_[read/write].
1701 The implementation of these are platform specific.
1703 * Added WIN32 specific routines of silc_socket_[read/write]
1704 to lib/silcutil/win32/silcwin32sockconn.c.
1706 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1708 * Added preliminary support for native WIN32 compilation under
1709 cygwin (using the -mno-cygwin option for GCC) to the
1710 ./configure.in.pre. The --with-win32 now prepares the
1711 compilation for native WIN32.
1713 * Rewrote the SILC Scheduler interface in the file
1714 lib/silcutil/silcschedule.h. The scheduler is now context
1715 based and does not have anymore any global static scheduler.
1716 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1717 and created lib/silcutil/win32 directory for WIN32 based
1720 * Added Unix specific network routines to the
1721 lib/silcutil/unix/silcunixnet.c and the old
1722 lib/silcutil/silcnet.c includes now only generic routines.
1724 Added WIN32 specific network routines to the
1725 lib/silcutil/win32/silcwin32net.c.
1727 * Added Unix specific utility functions from the
1728 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1730 * Added WIN32 SILC Scheduler to the file
1731 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1734 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Do not handle JOIN notify in the server if the target client
1737 is not registered (idata->registered == FALSE). The affected
1738 file is silcd/packet_receive.c.
1740 * Update the nickrec->founder in event_cumode in the Irssi SILC
1741 client. Affected file irssi/src/silc/core/silc-channels.c.
1743 * Fixed the CUMODE_CHANGE notify handling in the server when
1744 server and router are announcing their clients on channels.
1745 Now the mode changes are saved and notified correctly. The
1746 affected file is /silcd/packet_receive.c.
1748 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1749 They really did not replace the cache entry in the ID Cache.
1750 Now they do that. Affected file silcd/idlist.c.
1752 * Fixed the KICK notify handling in the Irssi SILC client to
1753 update the channel records so that the kicked client does not
1754 appear to be on the channel. The affected file is
1755 irssi/src/silc/core/silc-channels.c.
1757 * Always update the conn->current_channel when executing command
1758 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1760 * Fixed the KILL notify handling in Irssi SILC client to remove
1761 the killed client on all channels.
1763 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1765 * Fixed the silc_parse_command_line to remove extra spaces
1766 from the start and end of the arguments. Affected file is
1767 lib/silcutil/silcutil.c.
1769 * Cancel and free any active protocol in the function
1770 silc_server_close_connection. Affected file silcd/server.c.
1772 * Cancel and free any active protocol in the function
1773 silc_client_close_connction. Affected file is
1774 lib/silcclient/client.c.
1776 * Do not execute the KILL command for clients that are in
1777 history (ie. they are not in the network). Affected file is
1780 * Fixed KILL notify handling, client does not crash anymore.
1781 Affected file irssi/src/silc/core/silc-channels.c.
1783 * Reduced the default packet buffer size from 2048 to 1024 in
1784 lib/silccore/silcpacket.c.
1786 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1787 counter to the SKE context that is incresed when the SKE library
1788 performs async operation outside the library. If the outside
1789 process frees the SKE context and FREED status will be set
1790 and the library will detect after the sync operation that the
1791 libary is freed. The affected files are
1792 lib/silcske/silcske[_status].[ch].
1794 * Resolve the client entry information in the function
1795 silc_client_channel_message to assure that NULL pointer is not
1796 passed as client entry to the application. */
1798 * Fixed the task timeout calculation to assure that there is
1799 never negative timeouts. The affected file is
1800 lib/silcutil/silcschedule.c.
1802 * Fixed the channel user mode notification sending in server.
1803 It was sent point-to-point to the router (or to server by router)
1804 but it needs to be destined to a channel. The routines now
1805 supports sending the channel user mode notifys to the channels
1806 when announcing clients and channels. Affected files are
1807 silcd/server.c and silcd/packet_receive.c.
1809 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1810 It did not actually replace the old channel entry in the cache.
1811 Affected file lib/silcclient/client_notify.c.
1813 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Fixed a possible crash in silc_packet_send_prepare. It now
1816 assures always that there is enough space in the buffer and
1817 at the tail area of the buffer (for MAC).
1819 Fixed the inbound buffer reallocation in silc_packet_read.
1820 It was old code and did not handle the reallocation correctly.
1823 The affected file is lib/silccore/silcpacket.c.
1825 * Fixed buffer overflow in silc_parse_nickname in the file
1826 lib/silcutil/silcutil.c.
1828 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * make install generates new server keys only if there is not
1833 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1836 Added check that if the NOREPLY is set then we will not send
1837 the away message. This avoids infinite loop of away messages
1838 if both clients are away. The affected file is
1839 lib/silcclient/client_prvmsg.c.
1841 * Fixed client crash if /NICK was given without arguments.
1842 Affected file lib/silcclient/command.c.
1844 * Server does not send the invite list in INVITE command back
1845 to the client if the list was not altered. Added this notion
1846 to the protocol spec as well. Affected file silcd/command.c.
1848 Fixed possible crash in INVITE command by checking the
1849 value of silc_server_get_client_route command.
1851 * Fixed the INVITE notify type handling. The arguments are now
1852 taken in correct order and client does not crash. The affected
1853 file is irssi/src/silc/core/silc-channels.c.
1855 Removed the "Inviting xxx to channel" message from the
1856 client library away and let the application handle it.
1857 Affected file lib/silcclient/command.c. Added that message
1858 to Irssi SILC client's message formats.
1860 * Fixed CMODE command crash in client. It now checks the
1861 amount of arguments correctly and does not crash. The affected
1862 file is lib/silcclient/command.c.
1864 * Do not create new channel automatically in silc_channels_join
1865 but check whether the channel by that name already exists.
1866 Affected file irssi/silc/core/silc-channels.c.
1868 * Do not send the SERVER_SIGNOFF to router if the disconnected
1869 entity was the router. Affected file silcd/server.c.
1871 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1872 SILC client as it was missing from there.
1874 Added the handling of the KICK notify to the Irssi SILC client
1875 as it was missing. Added "you have been kicked" message to
1876 Irssi SILC client's message modules formats.
1878 Added the handing of the KILL notify to the Irssi SILC client
1879 as it was missing. Added the kill message module formats
1882 The affected file is irssi/src/silc/core/silc-channels.c.
1884 * The router did not save the channel mode the server announced.
1885 Affected file silcd/packet_receive.c.
1887 * Fixed a possible crash in INFO command in server. If the
1888 server did not provide the server info it crashed. Affected
1889 file silcd/command.c.
1891 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * Fixed the GETKEY command in the server to check also the
1894 global list. Otherwise the GETKEY would not work correctly
1895 in normal SILC server. Affected file silcd/command.c.
1897 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Fixed GETKEY crash, it crashed if the command did not succseed.
1901 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1904 is now real and not just an macro interface to GMP.
1906 Removed the entire GMP from the source tree and imported new
1907 NSS MPI library instead. Reason for removing GMP is that it is
1908 extremely large and compiles extremely slow. The NSS MPI
1909 is only a few files and compiles in less than 10 seconds.
1910 The speed is also about the same as GMP. The MPI is imported
1911 to lib/silcmath/mpi.
1913 If the system has GMP installed we will still use the GMP.
1914 If it is not then the NSS MPI will be compiled.
1916 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1918 * Merged a long nickname (127 characters long) crash bugfix from
1919 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1921 * Merged a freed memory reference bugfix from Irssi CVS tree.
1922 Affected file irssi/src/core/commands.c.
1924 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Added the server's public key sving and verification to the
1927 server when performing the SKE. This was missing and the
1928 remote server's (or router's) public key was accepted without
1929 checking whether we have it previously or trust it at all.
1930 Affected file silcd/protocol.c.
1932 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1934 * Check in the silc_server_timeout_remote if protocol is active
1935 and make sure that the protocol's final callback is called so
1936 that all memory if freed. Affected file silcd/server.c.
1938 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1940 * silc_server_whois_send_reply crashed the server if the nickname
1941 was 127 characters long. Affected file silcd/command.c.
1943 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Added sanity check to the silc_server_new_client. If the hostname
1946 is provided inside username then check that the provided hostname
1947 really is the same as the resolved one. If the hostname was not
1948 resolved then check it from the public key. Affected file is
1949 silcd/packet_receive.c.
1951 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1952 if the server disconnected us and the connection is not valid
1953 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1955 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1956 the library to the lib/silcutil/silcutil.[ch].
1958 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Close log file after open. Affected file
1961 lib/silcutil/silclog.c.
1963 * Check whether sock == NULL in silc_client_send_packet and return
1964 if it is. Affected file lib/silcclient/silcclient.c.
1966 * Check rec->entry == NULL in the Irssi SILC Client before
1967 sending the channel message. Affecte file is
1968 irssi/src/silc/core/silc-servers.c.
1970 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Merged a splitted window bugfix from Irssi CVS tree. The
1973 affected file is irssi/src/fe-text/textbuffer-view.c.
1975 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1976 It did not print nickname.
1978 * Improved the distributions system a bit.
1980 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1983 irssi/src/fe-text/gui-window.c.
1985 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1986 to in-active server. The affected file is
1987 irssi/src/silc/core/client_ops.c.
1989 * Resolve the client in USERS command reply if the entry does
1990 not have username resolved. The affected file is
1991 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1992 command to WHOIS command to really resolve stuff. The USERS
1993 is not used any more in any critical section so WHOIS can
1994 be used even though it might be slower than IDENTIFY.
1996 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1999 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2001 * Changed the protocol API a bit more consistent in the
2002 lib/silccore/silcprotocol.[ch].
2004 * Changed the following headers to ROBODoc format:
2006 lib/silccore/silcpayload.h
2007 lib/silccore/silcprotocol.h
2008 lib/silccore/silcsockconn.h
2010 All core library headers are now formatted.
2012 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Fixed a bug in Irssi SILC client; do not show that you are
2015 server/router operator if you really are not. Affected file is
2016 irssi/src/silc/core/client_ops.c.
2018 * Renamed silc_command_free_payload to silc_command_payload_free.
2019 Affected file lib/silccore/silccommand.h
2021 * Added silcmath.h to include the prototoypes of various routines
2022 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
2025 * Changed the following headers to ROBODoc format:
2027 lib/silccore/silcchannel.h
2028 lib/silccore/silccommand.h
2029 lib/silccore/silcid.h
2030 lib/silccore/silcidcache.h
2031 lib/silccore/silcmode.h
2032 lib/silccore/silcnotify.h
2033 lib/silccore/silcpacket.h
2034 lib/silcmath/silcmath.h
2036 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Added checking to the server code not to start the server if
2039 ciphers and stuff are not configured properly. Affected files
2040 silcd/serverconfig.[h] and silcd/server.c.
2042 * Changed the layout of the header files of the public interfaces
2043 in the SILC libraries. The new layout supports ROBODoc
2044 documentation tool (and some others) so that it is easy to create
2045 a library reference manual. All the other headers and source
2046 code must still follow the CodingStyle document. Also source
2047 code must not include these ROBODoc stuffs, only the headers.
2048 Furthermore, all public interface headers must now be named
2049 by using `silc' prefix, example: silcapi.h, silccipher.h.
2050 Some files were renamed due to this. All the other headers
2051 must not be used as public interfaces. I will update the
2052 CodingStyle document later. Changed following headers, so far:
2054 lib/silcclient/silcapi.h
2055 lib/silccore/silcauth.h
2056 lib/silccore/silcprivate.h
2057 lib/silccrypt/silcdh.h
2059 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Removed silc_client_packet_send_flush from the client library
2064 as it is not needed. Affected file lib/silcclient/client.[ch].
2066 * Added printing of message of unresolved authentication method
2067 to the Irssi SILC client. Added it to the module formats.
2068 Removed the same message from the client library.
2070 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2072 * Added new distribution feature, DISTLABEL. Every distribution
2073 can define own preprocessor label that can be used in the
2074 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
2075 file distributions, acconfig.h.pre and prepare.
2077 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Added Makefile.defines_int to include the actual definitions
2080 for Makefile.defines.in. Tested the new distribution system,
2081 created distributions and tested installation.
2083 * Added AWAY message printing to the Irssi SILC client. Added
2084 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
2086 * Added SCONNECT command to call the SILC's CONNECT command.
2087 Cannot use CONNECT directly since Irssi uses that internally.
2088 Affected file irssi/src/silc/core/silc-servers.c.
2090 Added ACTION local command. It is same as ME command but takes
2091 the channel as mandatory argument.
2093 Rewrote some of the Irssi's help files to suite for SILC
2096 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Added Makefile.defines[.in] that should for now on be included
2099 in all Makefile.am file in the source tree. That file includes
2100 all common compilation definitions for SILC source tree.
2102 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Minor changes to the ./prepare script to change the package
2105 name according the distribution name to the configure.in.
2107 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Created new distribution system. Added file `distributions'
2110 that defines all the distributions that can be created out of
2111 the SILC source tree. The ./prepare script now reads that
2112 file to determine how to prepare the distributions. The
2113 first argument to the ./prepare is the name of the distribution
2114 and second is the version of the distribution. If given
2115 without arguments it creates the default (toolkit) distribution
2116 with the default version (defined in ./prepare).
2118 All Makefile.am files that are subject to the distributions
2119 are now named as Makefile.am.pre. These are ./Makefile.am
2120 and lib/Makefile.am. Others may be changed later.
2122 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Added invite list, ban list, some key management and connection
2125 error message printing to module formats in the Irssi SILC client.
2127 * Added new silc_client_set_away_message to set the away message
2128 that is back to the person who sent private message. The
2129 affected file lib/silcclient/silcapi.h and the
2130 lib/silcclient/client_prvmsg.c.
2132 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Fixed the private message sending in the Irssi SILC client,
2135 added local command KEY to the Irssi SILC client.
2137 Added key management and key agreement message formats to the
2138 irssi/src/fe-common/silc/module-formats.[ch].
2140 Added USERS (alias WHO) printing, server/router operator
2141 indication and LIST command printing to the module formats.
2143 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Fixed channel joining notify handling, cumode notify handling
2146 from Irssi SILC client.
2148 * Added SILC specific module-formats to the Irssi SILC client so
2149 that SILC specific message hilighting, colors etc is possible.
2150 Affected file irssi/src/fe-common/silc/module-formats.[ch].
2152 Added channel mode, channel user mode, actions, notices,
2153 whois and whowas printing to the the module-formats.c.
2155 * Fixed a bug in channel deletion in the server. The channel
2156 is not left to the cache even if the channel founder auth mode
2157 is set when there are no users anymore on the channel. Affected
2158 file silcd/server.c.
2160 * The silc_net_localhost now resolves the entire hostname including
2161 the domain name. Affected file lib/silcutil/silcnet.c.
2163 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2165 * Changed the ask_passphrase client operation to be ascynchronous.
2166 It has now a completion callback and a context that the
2167 application must call after it has got the passphrase from
2168 the user. Affected files lib/silcclient/silcapi.h,
2169 lib/silcclient/protocol.c, lib/silcclient/command.c and
2172 Added SilcAskPassphrase callback that the application calls
2173 to deliver the passphrase to the library.
2175 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
2176 The public key verification and especially a certificate
2177 verification is asynchronous procedure.
2179 Added new SILC_SKE_STATUS_PENDING status to indicate the
2180 request is pending and a callback will be called to finalize
2183 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
2184 indicate that remote end did not send its public key (or
2185 certificate), even though we require it. Added check for this
2186 condition in the SKE. This was a security bug, now fixed.
2188 Defined new SilcSKEVerifyCbCompletion callback that is called
2189 when the verification process is completed.
2191 The affected files lib/silcske/silcske_status.h and
2192 lib/silcske/silcske.[ch].
2194 * Changed the verify_public_key client operation to be async
2195 as well. Defined SilcVerifyPublicKey callback that is used to
2196 indicate the success of the public key verification process.
2198 Changed the server and client to use the new async client
2201 * Changed the Irssi SILC client's internal scheduler to be called
2202 twice as many times as it used to be. As a result the client
2203 should be a bit faster now. Affected file is
2204 irssi/src/silc/core/silc-core.c.
2206 * Added support to Irssi SILC client of asynchronous public key
2207 verification and passphrase inquiry. Affected file is
2208 irssi/src/silc/core/silc-core.c.
2210 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2212 * Do not say "You have left channel %s" in client library.
2213 Moved it to the application. Affected files are
2214 lib/silcclient/command.c and silc/client_ops.c.
2216 * Fixed silc_client_get_clients. Command context was not
2217 duplicated and was freed memory in the callback. Affected
2218 file lib/silcclient/idlist.c.
2220 * Do not say "you are now talking..." on JOIN command in the
2221 client library. The appliation must handle it.
2223 * Do not say ".. changed topic to" in command reply in the
2224 client libary. The application must handle it.
2226 * Fixed TOPIC command sending in the client library.
2228 * Fixed a memory leak in silc_client_command_free in the file
2229 lib/silcclient/command.c.
2231 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Imported a modified version of Irssi client to the source tree.
2234 The Irssi will be used to create a new client called
2235 Irssi SILC. Imported to irssi/.
2237 Added silc_core_init_finish function to the Irssi. Affected
2238 file irssi/configure.in.
2240 A lot changes in the Makefile.ams around the irssi tree.
2242 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2244 * Do not rehash if the new size is same as the old size of the
2245 hash table, in the silc_hash_table_rehash*. The affected file
2246 lib/silcutil/silchashtable.c.
2248 * Replaced hash_table_del_by_context calls from the server
2249 (when channel->user_list and client->channels) to the
2250 hash_table_del as it is sufficient and faster.
2252 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2254 * Added silc_hash_table_list, silc_hash_table_get and the
2255 SilcHashTableList structure to provide an alternative way to
2256 traverse the hash table. The affected files are
2257 lib/silcutil/silchashtable.[ch].
2259 * Changed the server's idlist routines to use the hash table
2260 routines to optimize the code.
2262 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Replaced the client entry's `channel' list and channel entry's
2265 `user_list' list to hash tables for optimized lookup. Changed
2266 the code to use the hash table interface around the code.
2267 Affected file lib/silcd/idlist.[ch].
2269 * Added `auto_rehash' boolean argument to the function
2270 silc_hash_table_alloc to indicate whether the hash table should
2271 auto-rehash when it thinks is appropriate time. It will
2272 increase the hash table size if the there is twice as much
2273 entries in the table than the size of the table, and will
2274 decrease the size if there are twice as less entries than
2275 the size of the table.
2277 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2279 * Fixed silc_xxx_get_supported to not crash at some circumstances.
2281 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * silc_idcache_purge_by_context deletes the entry now by context
2284 as it is supposed to do. Affected file lib/silccore/idcache.c.
2286 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
2287 client is not anymore valid (WHOWAS givens the info) and not
2288 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
2290 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Removed the `data' and `data_len' arguments from the ID Cache
2293 interfaces and added `name' argument. ID Cache does not handle
2294 anymore the binary data only a names associated with given ID.
2296 * When hashing a Client ID with silc_hash_id the entire ID is
2297 not hashed anymore, instead only the hash of the Client ID is
2298 hashed. This way we can access the Client ID from the cache
2299 with Client ID but with the hash of the ID (which is a hash of
2300 the nickname) as well without any difference in performance.
2302 Added also silc_idcache_find_by_id_one_ext to do one on one
2303 searching when we have the actual ID. Added also function
2304 silc_hash_client_id_compare. The affected files are
2305 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
2307 * When hashing the name associated with a ID it is always done
2308 in lowercase. This way we can access the cache without worrying
2309 about case-sensitivity, even though, for example nicknames are
2312 * Fixed a bug in server with channel message sending. It put
2313 wrong ID type as destination ID. The affected file
2314 silcd/packet_send.c.
2316 * silc_idcache_del_by_context now deletes from all hash tables
2317 by context. Affected file lib/silccore/idcache.c.
2319 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2321 * Changed the client library to use the new ID Cache interface.
2322 Changes around the source tree.
2324 * Added silc_hash_table_rehash_ext to rehash with specific
2325 hash function. Affected file lib/silcutil/silchashtable.[ch].
2327 * Added silc_hash_string_compare to compare two strings in the
2328 hash table. Affected file lib/silcutil/silcutil.[ch].
2330 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2332 * Added new function silc_idcache_del_by_context into the
2333 lib/silccore/idcache.[ch].
2335 * Changed the server's ID list routines to use the new ID Cache
2336 interface. Changes around the source tree.
2338 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2340 * Added silc_hash_table_del[_by_context]_ext functions in to the
2341 lib/silcutil/silchashtable.[ch].
2343 Removed silc_hash_table_find_all* routines and added new
2344 silc_hash_table_find_foreach to replace them.
2346 Added silc_hash_table_replace_ext function as extended
2347 replacing function. Separated the simple hash table interface
2348 from the extended hash table interface in the file
2349 lib/silcutil/silchashtable.h.
2351 * Fixed minor bugs and changed it to use some of the new
2352 hash table functions in lib/silccore/idcache.c
2354 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2356 * Added new function silc_hash_table_find_all to return all keys
2357 in the hash table by the specified key. As the hash table is
2358 collision resistant it also makes it possible to have several
2359 duplicate keys in the hash table. This function may be used to
2360 find all of the keys from the hash.
2362 Added user_context arguments to the SilcHashFunction,
2363 SilcHashCompare and SilcHashDestructor to deliver user specified
2366 Added new fuctions silc_hash_table_find[_all]_ext to do
2367 extended lookup with specified hash and compare functions and
2368 specified user contexts.
2370 Added new function silc_hash_table_add_ext to add the key
2371 with specified hash function and user context.
2373 Added new function silc_hash_table_foreach to traverse all
2374 entrys in the hash table. Added SilcHashForeach callback
2377 Added new function silc_hash_table_del_by_context to delete
2378 the entry only if the context associated with the key matches.
2380 Affected files are lib/silcutil/silchashtable.[ch].
2382 * Removed silc_hash_[server/client/channel]_id and added just
2383 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
2384 silc_hash_id_compare to compare two ID's using as the hash table
2385 comparison function. Added also silc_hash_data to hash
2386 binary data and silc_hash_data_compare to compare it.
2388 * Removed silc_idlist_find_client_by_hash as it is not needed
2389 anymore. Affected file silcd/idlist.[ch].
2391 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
2392 to use internally the SilcHashTable. The new ID Cache is a lot
2393 faster than the old one. Some of the ID Cache interface was also
2394 rewritten and obsolete and stupid functions were removed.
2396 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Added entry_count field to the SilcHashTable to keep the number
2399 of the entries in the table. Implemented the function
2400 silc_hash_table_rehash. Added new function
2401 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
2403 Fixed a minor bug in silc_hash_table_free.
2405 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
2406 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
2407 into the lib/silcutil/silcutil.[ch].
2409 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2411 * Implemented a collision resistant hash table into the
2412 lib/silcutil/silchashtable[ch]. See the header and the source
2413 for the SilcHashTable API.
2415 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2417 * Merged dotconf version 1.0.2 into lib/dotconf.
2419 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2421 * Do not compile anything in lib/silcsim/* if the SIM support
2422 is not enabled. The tree should now compile without problems
2425 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2427 * Compiled the SILC under cygwin. Compiled and tested briefly
2428 without problems. More tests needed. The SIMs didn't compile
2431 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
2433 * Fixed possible crash in silc_get_username in the
2434 lib/silcutil/silcutil.c.
2436 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Fixed a va_arg in silc/client_ops.c.
2440 * Oops, RC5 routines were named AES and caused some problems
2441 when not using SIM's. Affected file lib/silccrypt/rc5.c.
2443 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2445 * Added new SilcIDIP structure into the lib/silccore/id.h and
2446 replaced the old `ip' fields from all SILC ID's to that type.
2447 This is a step towards IPv6 support.
2449 The silc_id_get_len takes now the ID as an extra argument.
2450 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
2451 both IPv4 and IPv6 based ID's.
2453 The affected files are lib/silccore/id.[ch] and other files
2454 around the tree using these routines.
2456 * Removed the ID length arguments in server from various
2457 silc_server_send_notify_* routines -> they are not needed
2460 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2462 * Fixed memory leak in silc_encode_pem_file in the file
2463 lib/silcutil/silcutil.c.
2465 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Check minor version as well in the SKE. Affected files are
2468 silcd/protocol.c and lib/silcclient/protocol.c.
2470 * Added --identifier option to the server so that an identifier
2471 can be when creating the public key for the server. Affected
2472 file is silcd/silcd.c.
2474 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
2475 lib/silccrypt/silcpkcs.c.
2477 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Register default ciphers and stuff when using -C option with
2480 the server. Affected file sildc/silcd.c.
2482 * Put back the servers public key filename format, it is better
2483 than the new one. For now, the client keys are saved with the
2484 new filename format. The affected file silc/client_ops.c.
2486 * Implemented the Cipher API for the rest of the ciphers that
2487 did not implement it or implemented it the wrong way.
2489 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Register default ciphers and stuff when using the -S option
2492 in the client. Affected file silc/silc.c. Same also when
2493 creating new key pair with -C option.
2495 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Fixed the silc_verify_public_key client operation function to
2498 save the public keys differently. The fingerprint is now
2499 used as filename and not the hostname. This way also the
2500 client keys are saved uniquely and not with hostnames. The
2501 affected file is silc/client_ops.c.
2503 * Trimmed the silc_hash_fingerprint function to remove extra
2504 whitespaces from the end of the fingerprint. The affected
2505 file is lib/silccrypt/silchash.c.
2509 * Added silc_cipher_register_default function to register all
2510 default ciphers. It can be used when configuration files
2511 does not exist and the application does not want any specific
2512 ciphers in any specific order.
2514 The SilcDList is now used as silc_cipher_list dynamically
2515 allocated cipher list. Removed the static list all together
2516 and now all ciphers must be allocated to the dynamic list.
2517 The silc_cipher_alloc routine was changed to check only the
2520 All silc_cipher_* routines that used to return int returns
2523 The affected files lib/silccrypt/silccrypt.[ch].
2525 * The same thing was done to silc_hash_* as for silc_cipher_*
2526 routines. Affected files lib/silccrypt/silchash.[ch].
2528 * The same thing was done to silc_pkcs_* as for silc_cipher_*
2529 routines. Affected files lib/silccrypt/silcpkcs.[ch].
2530 Added also silc_pkcs_[un]register[_default] functions.
2531 Removed the data_context from the PKCS API.
2533 * Added silc_hmac_register_default function to register default
2534 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
2535 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
2536 to unregister all hmacs at once.
2538 * Register the default ciphers, hash functions, PKCSs and HMACs
2539 if client's configuration file does not exist. The affected
2542 * The client did not load the hash functions from the SIM
2543 modules at all. Added support for this. Affected file is
2544 silc/clientconfig.c.
2546 * When decoding public key with silc_pkcs_public_key_decode, check
2547 the supported algorithm only if PKCS are registered. Affected
2548 file lib/silccrypt/silcpkcs.c. The same was done with the
2549 silc_pkcs_private_key_decode.
2551 * Fixed the SILC List routines to keep the list always in order.
2552 It used to change the list's order when traversing the list but
2553 not it preserves the order. Affected file lib/trq/silclist.h.
2555 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Added the client library to use the SilcSocketConnection's
2558 reference counter (by silc_socket_dup) to prevent the bug that
2559 the socket object may be freed underneath async operation.
2561 * The name resolv library checking fixes in the configure.in.pre.
2564 * Created new version of the protocol drafts for future
2565 development. The -03 drafts are the ones that will be changed
2566 in the trunk now and the -02 will remain as they are.
2568 * Send list of CUMODE notifys to the router when announcing
2569 the channel users to the router. Affected file silcd/server.c.
2570 If the router receiving channel founder CUMODE for a channel
2571 that already has channel founder it will send CUMODE notify
2572 to the sender to remove the channel founder rights from the
2573 announced client. Affected file silcd/packet_receive.c.
2575 * The CUMODE notify may now use Server ID as well as the entity
2576 who changes the mode. Updated protocool specs.
2578 * Updated INSTALL and README files.
2580 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * New web pages in the http://silc.pspt.fi. The pages was
2587 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Implemented the [DenyConnectin] config section in the server.
2590 Added silc_server_config_denied_conn to check whether incoming
2591 connection is denied. Affected file silcd/serverconfig.[ch].
2593 * Do not check the ports when checking the incoming configuration
2594 data if the port is 0, meaning any. Affected file is
2595 silcd/serverconfig.c.
2597 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Fixed buffer overflow in silc_string_compare in the file
2600 lib/silcutil/silcutil.c.
2602 * Fixed double free in silc_server_command_leave in the file
2605 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2607 * Fixed the version checking in the server. Affected file is
2610 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Fixed the configuration data fetching when accepting new
2613 connections in the server. Affected file silcd/server.c.
2615 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2617 * Added `sender_entry' argument to the function
2618 silc_server_packet_relay_to_channel so that we can check
2619 whether some destination actually belongs to the same route
2620 the sender belongs (ie, we must not resend the packet to the
2621 sender). Affected file silcd/packet_send.[ch].
2623 * Added `servername' field to the SilcClientEntry in the server
2624 to hold the name of the server where client is from. Affected
2625 file is silcd/idlist.h.
2627 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Moved the channel message encrypting in the router betwen
2630 router connections from silc_server_channel_message to the
2631 silc_server_packet_relay_to_channel since we want to check
2632 whether we have anybody channel before encrypting anything.
2633 Affected files silcd/packet_[receive/send].c.
2635 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2637 * Fixed the [AdminConnection] server config section to support
2638 multiple entries. Affected file silcd/serverconfig.c.
2640 * Added support into the server to check the validity of the
2641 incoming connection before executing any KE or authentication
2644 * The connection configuration is now saved to the KE and
2645 connection auth protocol contexts and not fetched anymore in
2646 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
2648 * The local hosts listenning address and port is also resolved
2649 now when starting the server. We want to have the socket object
2650 to include the real address and port for the listener. Added
2651 new function silc_net_check_local_by_sock into the files
2652 lib/silcutil/silcnet.[ch].
2654 * Fixed a broadcast bug in server -> do not broadcast if we
2657 * Fixed a routing bug. Do not route broadcast packets ever.
2658 Broadcast packets must be processed always and not routed since
2659 they may be destined to some other host than yourself and thus
2660 would get routed without no good reason. Affected file is
2663 * Added function silc_server_config_is_primary_route to check
2664 whether primary router connection has been configured (a router
2665 configuration that we are initiating). If there is not, we
2666 will assume that there is only two routers in the SILC network
2667 and we will use the incoming router connection as our primary
2668 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
2670 * Changed the order of the broadcasting. Broadcast _after_ the
2671 packet has been processed not before. Affected file is
2674 * Fixed a [ClientConnection] parsing bug. The port was never
2675 parsed correctly thus resulting to port 0. Affected file
2676 silcd/serverconfig.c.
2678 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2679 argument and did not set the broadcast packet flag. Affected
2680 file silcd/packet_send.c. Fixed same bug in the function
2681 silc_server_send_notify as well.
2683 * If we receive NEW_ID packet for our own ID in the server, ignore
2686 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2690 * Removed the nickname from the Private Message Payload.
2691 Updated the code and the protocol specs.
2693 * Updated protocol specs for submitting to the IETF.
2695 * Tweaked the Random Number Generator a bit. Affected file
2696 lib/silccrypt/silcrng.c. Exported a new function
2697 silc_rng_[global]_add_noise which can be used to add more
2700 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Do not parse packets with different timeout when protocol
2703 is active -> may cause problem with rekey. Affected file
2706 * When server receives signoff notify it must not create
2707 new channel key if the client is on any channels since the
2708 sender of the signoff notify will create it.
2710 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * Added printing of error messages during SKE protocol from the
2713 failure packet sent by server during SKE. Affected file
2716 * Removed the client's failure_callback handling with timeout
2717 and handle it immediately when received.
2719 * The SKE library returned wrong type in SUCCESS and FAILURE
2720 packets. They must be 32 bit MSB not 16 bit MSB.
2722 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Ok, rewrote the logic of the re-key and now it seems to work.
2725 I tested it on high traffic with frequent re-keys without
2726 problems. Added hmac_receive (and renamed hmac to hmac_send)
2727 in SilcClientConnection in lib/silcclient/client.h and
2728 in SilcIDListData in silcd/idlist.h. Also, removed the
2729 SilcPacketParserContext's cipher and hmac fields as they are
2730 not needed anymore and actually caused some problems when
2731 the ciphers and hmac's changed underneath the packet parser.
2733 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * If re-key protocol is active then process the incoming packets
2736 synchronously since we must assure that icoming packets encrypted
2737 with the old key is processed before the new keys is set to
2738 use. This is true other packets than for REKEY packets.
2739 Affected file silcd/server.c. The same was done to client library
2740 as well, affected file lib/silcclient/client.c.
2742 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * Fixed bug in client and server to accept the force send if
2745 the packet is send from silc_[server/client]_packet_process
2746 function. Otherwise the packets are never delivered, oops.
2748 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2750 * Disable force sending of packets when REKEY protocol is active.
2751 We must assure that no packet is sent directly when rekey is
2752 performed. All packets must be sent through packet queue.
2753 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2754 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2755 function is silc_[server/client]_packet_send_real to check
2758 * Replaced the SIM paths from example config files to
2759 /usr/local/modules. Also, make install creates now
2760 /usr/local/silc/logs directory to hold all the SILC server
2763 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2765 * Made the configure.in.pre work on Solaris. Patch by salo.
2767 * Made all ciphers compatible with non-x86 machines. Defined
2768 CBC mode macros into lib/silccrypt/ciphers_def.h.
2770 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Fixed the make install.
2774 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2776 * When MAC computation fails the silc_packet_decrypt returned 0
2777 even though it was supposed to return -1. Fixed this. The
2778 affected file is lib/silccore/silcpacket.c.
2780 * Do not replace the config files in /etc/silc (in make install)
2781 if they already exist. Affected file ./Makefile.am.
2783 * Do not send re-key packets immediately but through packet queue.
2784 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2786 * Changed silc_net_check_host_by_sock to return FALSE if the
2787 IP/DNS could not be resolved. Though, it returns the IP address
2788 now even if it could not resolve it (but returns also FALSE).
2789 Affected file lib/silcutil/silcnet.[ch].
2791 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2793 * Added silc_pkcs_decode_identifier to decode the public key's
2794 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2795 Added also silc_pkcs_free_identifier. Added also new context
2796 SilcPublicKeyIdentifier.
2798 * Added -S option to the silc client. It is used to dump the
2799 contents of the specified public key file.
2801 * Changed the PKCS api to return the public key length when
2802 setting the public key.
2804 * Fixed a fatal bug in the public and private key file loading.
2805 Affected file lib/silccrypt/silcpkcs.c.
2807 * Execute the packet parsing for client with zero (0) timeout
2808 if the protocol is active. Affected file silcd/server.c.
2810 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2812 * Made the key generation options to the silcd program. Added
2813 -C option, equivalent to client's option.
2815 * Added new [ServerKeys] config section to the server. It
2816 configures the server's public and private key.
2818 * Defined generic Public Key Payload into the protocol
2819 specification to send specific type of public keys and
2822 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2823 public key or certificate.
2825 * Implemented the GETKEY command to the server and to the
2826 client library and on user interface.
2828 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2830 * Made preliminary `make install' work.
2832 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Added SilcServerRekey context into silcd/idlist.h.
2836 * Added the PFS support as defined in the specification to the
2837 SKE protocol. Affected files lib/silcske/*.c.
2839 * Added `ske_group' field to the SilcServerRekey context to hold
2840 the number of the SKE group that is used with PFS in re-key.
2841 Affected file silcd/idlist.h.
2843 * Added PFS re-key support to the server. Affected file is
2846 * Added silc_protocol_cancel to cancel execution of the next
2847 state of the protocol. Affected file is
2848 lib/silccore/silcprotocol.[ch].
2850 * Added the re-key support with and without PFS to the client
2851 library. Re-key is performed once in an hour, by default.
2853 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2854 Added silc_client_rekey_callback and silc_client_rekey_final.
2855 Affected files are lib/silcclient/protocol.[ch] and
2856 lib/silcclient/client.[ch].
2858 * Removed the `hmac_key' and `hmac_key_len' fields from the
2859 SilcClientConnection structure; not needed. Affected file is
2860 lib/silcclient/client.h.
2864 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Do not ask whether user wants to use the negotiated private key
2867 for private messages, just use it. Affected file is
2868 silc/local_command.c.
2870 * Added `send_enc_key' and `enc_key_len' fields to the
2871 SilcIDListData structure since they are needed in the re-key
2872 phase. Affected file is silcd/idlist.[ch].
2874 * Implemented the simple re-key protocol into the server.
2875 Affected files silcd/server.c and silcd/protocol.[ch]. The
2876 re-key will be performed once in an hour, by default.
2878 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2879 Added silc_server_rekey, silc_server_rekey_callback and
2880 silc_server_rekey_final.
2882 * Removed Tunneled flag from the protocol. Updated the code
2883 and the specifications.
2885 * Adde `pfs' field to the SilcIDListData to indicate whether
2886 the PFS is to be performed in the re-key. Affected file is
2889 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2891 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2892 int64 of at least the xintXX size. If void * is less that 4
2893 bytes uint32 * will be used. Defined bool as boolean.
2895 * Changed _ALL_ unsigned long and unsigned int to uint32,
2896 unsgined short to uint16 in the source tree.
2898 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2899 not handle clients that has entry->data.registered == FALSE.
2900 They are not in the network anymore. Affected file is
2903 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2905 * Implemented the sending of the SERVER_SIGNOFF notify in the
2906 server. Affected file is silcd/server.c.
2908 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2909 Added also silc_notify_payload_encode_args into the
2910 lib/silccore/silcnotify.[ch].
2912 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2913 Affected file silcd/packet_receive.c.
2915 * Implemented the SERVER_SIGNOFF notify handling in the client
2916 library. Affected file lib/silcclient/client_notify.c. Also,
2917 implemnted the printing of the SERVER_SIGNOFF info to the
2918 application. Affected file silc/client_ops.c.
2920 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2921 if the deleting was successful. Affected file silcd/idlist.[ch].
2923 * Added support for public key authentication in the connection
2924 authentication protocol in the client library. Affected file
2925 lib/silcclient/protocol.c.
2927 * Changed the server's silc_idlist_get_clients_by_* interface
2928 to support already allocated array so that new entries may be
2929 added to pre-allocated array. Affected file silcd/idlist.[ch].
2930 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2931 and command replies.
2933 * All command reply functions in the server now calls the
2934 pending command callback even if error occured. This way the
2935 error will be delivered to the client as well. Affected files
2936 silcd/command.c and silcd/command_reply.c.
2938 * Fixed INFO command to return local server's info if no server
2939 was provided. Affected file lib/silcclient/command.c.
2941 * Removed RESTART command for good. Updated the code and the
2944 * Rewrote parts of the task system. It is a bit simpler now.
2945 Removed unsued task priorities. The affected files are
2946 lib/silcutil/silctask.[ch].
2948 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2950 * Moved the USERS printing from the library to the application.
2951 Affected files lib/silcclient/command.c and silc/client_ops.c.
2953 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added channel key re-key support. The re-key is perfomed
2958 only by the router and is done once in an hour. Added `rekey'
2959 field to the SilcChannelEntry in the server. Affected files
2960 silcd/server.c and silcd/idlist.h.
2962 * Added silc_task_unregister_by_context into the file
2963 lib/silcutil/silctask.[ch].
2965 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2967 * Added SILC_UMODE_GONE mode to indicate when the client is not
2968 present in the SILC network. Added also support to the local
2969 command AWAY that will set this mode. Added support of showing
2970 "xxx is gone" in WHOIS command. The USERS command shows the
2971 gone status as well.
2973 * Fixed setting server and router operator privileges in the
2974 server's UMODE command. Affected file silcd/command.c.
2976 * Merged the SKE KE1 and KE2 payloads into one payload. The
2977 new KE payload is equivalent to the old KE2 payload.
2979 Cleaned up the SKE Start Payload parsing. It now uses the
2980 simple buffer unformatting to do the parsing. A lot faster
2983 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2984 to the SKE that is used to indicate whether both of the SKE
2985 parties should perform authentication. By default only the
2986 responder performs authentication. By setting this flag also
2987 the initiator must do authentication. By default it is unset
2988 since in normal SKE case, client to server connection, only
2989 the responder should do authentication. When doing SKE between
2990 two clients both should perform authentication. Updated the
2991 code and the protocol specs.
2993 * A little fix to IDENTIFY command in the server. Search the
2994 client first by hash not nickname. Affected file is
2997 * Fixed the silc_client_close_connection to support closing
2998 the client to client connections wihtout deleting too much
2999 data. Affected file lib/silcclient/client.c.
3001 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
3002 are received if protocol used to be active but is not anymore
3003 the application would crash due to NULL pointer dereference.
3004 Affected files silcd/server.c and lib/silcclient/client.c.
3006 * Added `hash' field to the SilcClientConnection to include
3007 the hash function negotiated in the SKE protocol.
3009 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
3010 to set the channel founder authentication data. A client can
3011 claim the founder rights later by providing the authentication
3012 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
3013 This way the channel founder can regain the channel founder
3014 privileges even it is left the channel. This works only on
3015 local server and the client must be connected to the same
3016 server to be able to regain the founder rights. Updated the
3017 protocol specs accordingly.
3019 Added support to the CMODE command in the client to set the
3020 founder auth data. Read the README to see how to set it.
3022 Added support to the CUMODE command to claim the founder
3023 rights. Read the README to see how to do it.
3025 Added support for the founder authentication to the Channel
3026 Entry in the server. Affected file silcd/idlist.h.
3028 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
3029 server's CMODE command. Affected file silcd/command.c.
3031 * Added the following new functions into lib/silccore/silcauth.[ch]:
3032 silc_auth_get_method and silc_auth_get_data.
3034 * The server now saves the remote hosts public key to the
3035 SilcIDListData pointer. Affected file silcd/protocol.c.
3037 * The normal server now does not remove the channel entry from
3038 the cache if the founder authentication data is set. It used
3039 to remove it if the founder was the last one on the channel on
3040 the server and left the channel. The auth data is saved and
3041 if the channel is re-joined later the old entry is used with
3042 the old auth data. Affected files silcd/command_reply.c and
3045 * Removed the `pkcs' field from the SilcIDListData structure
3046 in the server; it is not used. Affected file silcd/idlist.h.
3048 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Fixed packet processing on slow links. Partial packets were
3051 never re-processed because the incoming data buffer was cleared
3052 by the application. Application must not directly clear the
3053 sock->inbuf, the packet processing routines handle it. Fixed
3054 this in client library and in server.
3056 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3058 * Fixed the WHOIS and IDENTIFY send reply function to really
3059 check whether to send list or just one entry. Affected file
3062 * Cleaned up the LEAVE command's channel key distribution. The
3063 affected file silcd/command.c.
3065 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
3066 can enforce the channel mode as well. In that case the ID
3067 includes the ID of the server. The code now enforces the
3068 mode change if the router have different mode than the server.
3070 * The notify client operation with CMODE_CHANGE notify can now
3071 return NULL client_entry pointer if the CMODE was not changed
3072 by client. Application must check for this.
3074 * Added <Server ID> argument to INFO command to support server
3075 info fetching by Server ID.
3077 * Added silc_server_announce_get_channel_users to get assembled
3078 packets of channel users of the specified channel. Affected
3079 file silcd/server.[ch].
3081 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
3082 was freed underneath the ID Cache.
3084 * Re-announce clients when the server received CHANNEL_CHANGE
3085 notify from the router. Affected file silcd/packet_send.c.
3087 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3089 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
3090 crashed since it did not handle the fact that there is no cipher
3091 called "3" and didn't check the error condition. Now fixed.
3093 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
3094 flag. It can be used to send message requests.
3096 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3098 * Implemented the RESTART command in the client.
3100 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
3101 notice type messages. Added notice printing to the user
3104 * The channel keys are not re-generated if the channel's mode
3105 is PRIVKEY, ie private key on the channel exists. Affected
3106 files silcd/server.c and silcd/command.c.
3108 * Fixed a little bug in channel message delivery when channel
3109 private keys are set in the server. Affected file is
3110 silcd/packet_send.c.
3112 * Changed the setting on channel->on_channel = TRUE from the
3113 silc_client_save_channel_key to the JOIN command reply. The
3114 key payload is not received if the private channel key is set.
3115 Affected file lib/silcclient/command_reply.c and the
3116 lib/silcclient/client_channel.c.
3118 * When the CMODE_CHANGE notify is sent and the channel private
3119 key mode is removed the channel key must be re-generated in
3120 other cells as well. Added this support for the router in the
3121 silcd/packet_receive.c.
3123 * Added new local command NOTICE to send notice message on
3124 channel. Affected file silc/local_command.[ch].
3126 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Added new local command ME to the client. It is used to send
3129 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
3130 some action. Affected file silc/local_command.[ch].
3132 * Changed channel_message and private_message client operations
3133 to deliver the message flags to the application. Added also
3134 the `flags' arguments to the silc_client_send_channel_message
3135 and silc_client_send_private_message functions. Affected file
3138 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3140 * Redefined the Private Message Payload to support private message
3141 keys and to support the new private message flags. Updated
3142 the protocol specs. Flags makes it possible to have for example
3143 CTCP style messages.
3145 * Added new type SilcPrivateMessagePayload and defined an API
3146 for it in the lib/silcclient/silcprivate.[ch].
3148 * Tested private message private keys successfully. Tested the
3149 private message key set, unset and list commands with the new
3152 * Redefined the Channel Message Payload to include the channel
3153 message flags (equal with private message flags) to support
3154 for example CTCP style messages.
3156 * Defined some of the message (for channel and private message)
3157 flags. Updated the protocol specs and added the flags to the
3158 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
3160 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Added SilcKeyAgreementStatus type to the key agreement routines
3163 to indicate the current status and error if one occured.
3164 The status types are defined in the lib/silcclient/silcapi.h.
3166 * Added new local command KEY that is used to set and unset private
3167 keys for channels, set and unset private keys for private messages
3168 with remote clients and to send key agreement requests and
3169 negotiate the key agreement protocol with remote client. The
3170 key agreement is supported only to negotiate private message keys,
3171 it currently cannot be used to negotiate private keys for channels,
3172 as it is not convenient for that purpose.
3174 * Fixed a minor pending callback setting bug in the function
3175 silc_client_get_client_by_id_resolve, now the function works.
3176 Affected file lib/silcclient/idlist.c.
3178 * Added function silc_net_get_local_port to get local bound
3179 port by socket. Added to lib/silcutil/silcnet.[ch].
3181 * Added `sockets' and `sockets_count' fields to the SilcClient
3182 object. They hold the sockets of the listenning sockets in
3183 the client. Listenning sockets may be for example the key
3184 agreement server. Affected file lib/silcclient/client.[ch].
3185 Added functions the silc_client_add_socket and the
3186 silc_client_del_socket. They are exported to the application
3189 * Added ~./silc/clientkeys to support other client's public keys.
3191 * Renamed verify_server_key client operation to verify_public_key
3192 and added one argument to indicate the type of the connection
3193 (server, client etc.).
3195 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Added silc_server_connection_auth_request to handle the
3198 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
3199 silcd/packet_receive.[ch].
3201 * Added silc_server_send_connection_auth_request into the
3202 silcd/packet_send.c to send the connection auth request packet.
3204 * Cleaned up the silcd/protocol.c a bit and fixed some memory
3207 * Fixed the public key authentication in responder side in the
3208 server. The `auth_data' pointer includes the SilcPublicKey
3209 not the path to the public key. Affected file silcd/protocol.c.
3211 * Implemented the public key authentication in the initiator side
3212 in the server. Affected file silcd/protocol.c.
3214 * Removed the [RedirectClient] config section from the server
3215 configuration. Is not needed and I don't want to implement it.
3217 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3219 * Cleaned up the CMODE command in the server. It now works
3220 correctly and supports all the modes defined in the protocol.
3221 Affected file is silcd/command.c.
3223 * Added `hmac_name' field to the SilcChannelEntry in the server
3224 to hold the default HMAC of the channel. It can be set when
3225 creating the channel (with JOIN command). Affected files
3228 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
3229 type to indicate the change of the current cipher and hmac
3230 on the channel. Client can safely ignore the <cipher> argument
3231 (if it chooses to do so) since the CHANNEL_KEY packet will
3232 force the channel key change anyway. The <hmac> argument is
3233 important since the client is responsible of setting the new
3234 HMAC and the hmac key into use.
3236 * Fixed the CMODE command in the client library as well.
3238 * Tested CMODE command in router environment successfully.
3240 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3242 * Show the version of the remote client (or server) when connecting
3243 to the server. It is logged to the log file. Affected file
3244 is silcd/protocol.c.
3246 * Fixed the KILLED notify handling in the client library. The
3247 client must be removed from all channels when receiving the
3250 Also, do not remove the client entry when giving the KILL
3251 command but when the KILLED notify is received.
3253 * Removed silc_idlist_find_client_by_nickname from the server.
3254 Not needed anymore. Affected files silcd/idlist.[ch].
3256 * Implemented the CHANNEL_CHANGE notify type handling to the
3257 server. Affected file silcd/server.c.
3261 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3263 * Added silc_server_send_notify_invite to send the INVITE
3264 notify between routers.
3266 * Implemented the INVITE command correctly to the server.
3268 * Implemented the INVITE notify type handling in the server.
3270 * Implemented the INVITE command to the client library and on the
3273 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3275 * Added function silc_server_get_client_resolve to find the
3276 client entry by ID from all ID lists and then resolve it
3277 (using WHOIS) if it cannot be found. Affected file is
3280 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3282 * Implemented the BAN command to the client library.
3284 * The JOIN command in the server now checks the invite list
3287 * Changed the silc_command_reply_payload_encode_va and the
3288 silc_command_payload_encode_va to support that if argument is
3289 NULL it ignores and checks the next argument. Affected file
3290 lib/silccore/silccommand.c.
3292 * Added silc_server_send_notify_ban to send the BAN notify
3293 type between routers.
3295 * Chaned the silc_notify_payload_encode to support that if
3296 argument is NULL it ignores and checks the next argument.
3297 Affected file lib/silccore/silcnotify.c.
3299 * Tested ban lists in router environment successfully.
3301 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Implemented BAN command to the server, in silcd/command.[ch].
3305 * Removed the BAN and INVITE_LIST modes from the CMODE command
3308 * Added function silc_string_match to regex match two strings.
3309 Affected files lib/silcutil/silcutil.[ch].
3311 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Redefined parts of the SilcChannelEntry in the server to support
3314 the new ban and invite lists.
3316 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3318 * Redefined the INVITE command. The same command can be used to
3319 invite individuals to the channel but also to manage the invite
3320 list of the channel (to add to and remove from the invite list).
3321 Updated the protocol specs.
3323 * Added new command SILC_COMMAND_BAN that can be used to manage
3324 the ban list of the channel. Updated the protocol specs.
3326 * Removed the channel modes: the SILC_CMODE_BAN and the
3327 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
3328 in the CMODE command. The equivalent features are now available
3329 using INVITE and BAN commands. Updated the protocol specs.
3331 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
3332 in the network about change in the current ban list. The notify
3333 type is not used by the client.
3335 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
3336 support the invite lists.
3338 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3340 * Added new function silc_string_regexify that converts string
3341 including wildcard characters into regex string that can
3342 be used by the GNU regex library. Added into the file
3343 lib/silcutil/silcutil.[ch].
3345 Added silc_string_regex_combine to combine to regex strings
3346 into one so that they can be used as one regex string by
3347 the GNU regex library. Added into the file
3348 lib/silcutil/silcutil.[ch].
3350 Added silc_string_regex_match to match two strings. It returns
3351 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
3353 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Imported GNU regex to the soruce tree into lib/contrib.
3356 Fixed some compiler warning from the regex.c.
3358 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Fixed MOTD command in the server to work in router environment.
3362 * Fixed the MOTD command in the client library to support
3363 the server argument in the command.
3365 * Added `nickname_len' argument to the silc_idlist_add_client
3366 in the server, as the `nickname' argument may be binary data
3369 * Added silc_idlist_get_channels to return all channels from
3372 * Implemented LIST command to the server. Affected file is
3375 * Implemented the LIST command to the client library and on the
3378 * Added [<user count>] argument to the LIST command reply.
3379 With private channels the user count is not shown.
3381 * Updated TODO and README.
3383 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3385 * The client entry's data.registered must be TRUE even with
3386 global client entry on global client list. The data.registered
3387 is used to check whether the client is anymore in the network,
3388 for example with WHOWAS command so it must be valid.
3390 * Fixed the WHOWAS command in the server. It now actually works
3391 in router environment. Added function into silcd/command_reply.c
3392 silc_server_command_reply_whowas_save.
3394 * Added silc_idlist_purge function to the silcd/idlist.c
3395 to periodically purge the ID Cache.
3397 * Fixed INFO command in the server. It works now in router
3398 environment. Added <server name> argument to the INFO command
3399 reply. Updated the protocol specs.
3401 * Fixed minor bug in silc_idcache_purge to not purge if the
3402 expire value is zero.
3404 * Fixed various bugs in WHOIS and IDENTIFY command handling as
3405 they were buggy because of the WHOWAS information.
3407 * Fixed local command MSG to handle the async resolving of
3408 the remote client properly. It used to fail the first MSG.
3409 Affected file silc/local_command.c.
3411 * Added `data_len' field to SilcIDCache context.
3413 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3415 * Update TODO. Todo in commands in the server.
3417 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3419 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
3420 used by routers as broadcast packet to inform other routers
3421 about the changed user mode.
3423 Implemented the notify handling in the server. Affected file is
3424 silcd/packet_receive.c. Added the function
3425 silc_server_send_notify_umode to the silcd/packet_send.[ch].
3427 * Added new generic Channel Payload and deprecated the New Channel
3428 Payload. The New Channel Payload is now the generic Channel
3431 * Added new argument `mode' to the silc_server_send_new_channel
3432 as it is required in the Channel Payload now.
3434 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
3435 and created a new and real SilChannelPayload to represent the
3436 new generic Channel Payload. Implemented the encode/decode
3437 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
3439 * Added silc_server_get_client_channel_list to return the list
3440 of channels the client has joined for WHOIS command reply.
3441 Affected file silcd/server.[ch].
3443 * Implemented the channel list sending in the WHOIS command reply
3444 in server and in the client.
3446 Implemented the channel list displaying on the user interface
3447 as well. Affected file silc/client_ops.c.
3449 * Added silc_channel_payload_parse_list to parse list of Channel
3450 Payloads. It returns SilcDList list of SilcChannelPayloads.
3451 Client for example can use this function to parse the list of
3452 channels it receives in the WHOIS command reply. The caller
3453 must free the list by calling silc_channel_payload_list_free.
3454 Affected files lib/silccore/silcchannel.[ch].
3456 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3458 * Added one new argument <user mode> to the WHOIS command reply
3459 to return the mode of the user in SILC. Updated the protocol
3462 Implemented it to the server and client.
3464 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3466 * Fixed the mode printing on the user interface on joining.
3467 Affected file silc/client_ops.c.
3469 * Implemented the UMODE command and user modes in general to the
3470 client library and to the user interface.
3472 * Implemented the UMODE command to the server.
3474 * The server now sends UNKNOWN_COMMAND error status if client sends
3475 unknown command. Affected file silcd/command.c.
3477 * All server commands now handle the command identifier the right
3478 way when sending the command reply to the client. The client can
3479 use to identify the command replies with the identifier.
3481 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3483 * Added silc_server_get_client_route to resolve the route to
3484 the client indicated by the client ID. Affected file is
3487 * Added silc_server_relay_packet as general function to relay
3488 packet to arbitrary destination. This deprecates functions
3489 like _send_private_message_key, _relay_notify etc. Affected
3490 file is silcd/packet_send.[ch].
3492 Removed silc_server_send_key_agreement,
3493 silc_server_send_private_message_key and
3494 silc_server_packet_relay_notify functions from the file
3495 silcd/packet_send.[ch].
3499 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
3500 server. Affected file silcd/packet_receive.[ch].
3502 * Implemented the KILL command to the client. Implemented the
3503 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
3504 Affected files lib/silcclient/command[_reply].c and
3505 lib/silcclient/client_notify.c. Implemented the KILL notify
3506 printing in the user inteface.
3508 * Fixed a lot silc_parse_nick memory leaks from the client
3509 library in the file lib/silcclient/command.c.
3511 * Changed the silc_server_send_notify_on_channels's `sender'
3512 argument from SilcSocketConnection to SilcClientEntry to
3513 check the sender as entry and not as connection object and not
3514 to send to the client provided as argument. The affected file
3515 is silcd/packet_send.[ch].
3517 * The notify packets that are destined directly to the client used
3518 to not to be processed by the server. Now changed that and the
3519 server processes all notify packets. After relaying the packet
3520 to the client the notify packet is processed in the server.
3522 * The silc_server_free_client_data now checks whether there is
3523 pending outgoing traffic for the client and purges the data to
3524 the network before removing the client entry.
3526 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3528 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
3529 an client is killed from the SILC Network. Updated the protocol
3532 Added new function silc_server_send_notify_killed to the
3533 silcd/packet_send.[ch].
3535 * Added function silc_server_packet_relay_notify to relay notify
3536 packets that are destined directly to a client. In this case
3537 the server does not process the notify packets but merely relays
3538 it to the client. Affected file silcd/packet_send.[ch].
3540 Added also silc_server_packet_process_relay_notify to check
3541 whereto relay the notify. Affected file is
3542 silcd/packet_receive.[ch].
3544 * Implemented the KILL command to the server.
3548 * Added the backup schema desgined last fall to the protocol
3549 specs for everyone to see. The specification is in the
3550 *-spec-xx.txt draft and the packet type definitions for the
3551 backup routers is in *-pp-xx.txt draft. Thusly, added also
3552 new packet type SILC_PACKET_CELL_ROUTERS.
3554 * A big security problem in the implementation discovered. The
3555 signoff of an client did not cause new channel key generation
3556 which it of course should've done. The channel keys must be
3557 always re-generated when client leaves (or signoffs) the channel.
3558 The silc_server_remove_from_channels funtion now handles
3559 the channel key re-generation.
3561 * Added `sender' argument to the silc_server_send_notify_on_channels
3562 to not to send the client provided as argument. Affected file
3563 silcd/packet_send.[ch].
3565 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3567 * Implemented OPER and SILCOPER commands into the server and
3570 * Added silc_auth_verify and silc_auth_verify_data to verify
3571 the authentication directly from the authentication payload.
3572 It supports verifying both passphrase and public key based
3573 authentication. Affected file lib/silccore/silcauth.[ch].
3575 * Added `hash' field to the SilcIDListData structure. It is the
3576 hash negotiated in the SKE protocol. Affected file is
3579 * Slight redesigning of the SilcAuthPayload handling routines.
3580 Do not send SilcPKCS but SilcPublicKey as argument.
3582 * Implemented the public key authentication support to the
3583 serverconfig. The public key is loaded from the provided path
3584 and saved as authentication data to void * pointer. Thus,
3585 changed the unsigned char *auth_data to void *auth_data;
3587 * Fixed SHUTDOWN command to send the reply before the server
3588 is shutdown. :) Affected file silcd/command.c.
3590 * Fixed fatal bug in CONNECT command. The hostname was invalid
3591 memory and server crashed. Affected file silcd/command.c.
3593 * Fixed fatal bug in CLOSE command. The server_entry became
3594 invalid but was referenced later in the command. Affected file
3597 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Fixed fatal bug in failure packet handling. Server ignored
3600 the failure and thus crashed when it came.
3604 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3606 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
3607 that the command may be executed only once in (about) 2 seconds.
3608 The old SILC_CF_LAG flag is same but allows command bursts up
3609 to five before limiting.
3611 Added the support for CF_LAG and CF_LAG_STRICT flags to the
3612 server code. Various commands now includes the CF_LAG_STRICT
3613 flag to disallow any kind of miss-use of the command.
3615 * Fixed the silc_buffer_unformat to not to allocate any data
3616 if the length of the data is zero. It used to allocate the
3617 length + 1. Affected file lib/silcutil/silcbuffmt.c.
3619 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3621 * Changed the format of AdminConnection configuration section
3622 in the server. Added username of the admin to the format.
3623 Affected files silcd/serverconfig.[ch].
3625 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
3626 to return admin configuration data by host, username and/or
3629 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3631 * Implemented WHOWAS command to the server. Added the functions:
3633 silc_server_command_whowas_parse,
3634 silc_server_command_whowas_send_reply,
3635 silc_server_command_whowas_from_client and
3636 silc_server_command_whowas_from_server
3638 * Added <Client ID> argument to the WHOWAS command reply. Updated
3639 the protocol specs accordingly.
3641 * Implemented WHOWAS command and command_reply to the client
3644 Implemented the WHOWAS printing on the user interface.
3646 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3648 * Added new argument to the WHOWAS command reply, the real name.
3649 It is an optional argument. Updated the protocol specs.
3651 * Added SilcIDCacheDestructor callback that is registered when
3652 the SilcIDCache is allocated. The callback is called when
3653 an cache entry in the ID Cache expires, or is purged from the
3654 cache. Added into lib/silccore/idcache.[ch].
3656 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
3657 to destruct the client entries when the cache entry expires.
3658 Other ID Cache's in server and in the client library ignores
3661 * If the ID Cache entry's `expire' field is zero then the entry
3662 never expires. Added boolean `expire' argument to the
3663 silc_idcache_add function in the lib/silccore/idcache.[ch].
3664 If it is TRUE the default expiry value is used.
3666 * Added silc_server_free_client_data_timeout that is registered
3667 when client disconnects. By default for 5 minutes we preserve
3668 the client entry for history - for WHOWAS command.
3670 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3672 * Added support to the server to enforce that commands are not
3673 executed more than once in 2 seconds. If server receives
3674 commands from client more frequently, timeout is registered
3675 to process the commands. Affected file silcd/command.c.
3676 Added new function silc_server_command_process_timeout.
3678 * Changed NICK_NOTIFY handling in client library to check that
3679 if the client's nickname was changed, so there is no need to
3680 resolve anything from the server.
3682 * Removed error printing from the WHOIS and IDENTIFY commands.
3683 If error occurs then it is ignored silently in the client library.
3684 The application, however, may map the received error to
3685 human readable error string. The application currently maps
3686 the NO_SUCH_NICKNAME error to string.
3688 * Made the command status message public to the application. Moved
3689 them from lib/silcclient/command_reply.c to
3690 lib/silcclient/command_reply.h. The application can map the
3691 received command status to the string with the
3692 silc_client_command_status_message function.
3694 * Added check to the server to check that client's ID is same
3695 as the Source ID in the packet the client sent. They must
3698 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3700 * Added dist-bzip hook to the Makefile.am to make bzip2
3701 compressed distributions.
3703 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Server now enforces the maximum length for the nickname and
3706 the channel as protocol specification dictates. 128 bytes for
3707 nickname and 256 bytes for channel name.
3709 * Moved the WHOIS printing to the application. The client libary
3710 does not print out the WHOIS information anymore, the application
3711 must do it. Renamed silc_client_command_reply_whois_print to
3712 the silc_client_command_reply_whois_save.
3714 The client's idle time is also sent to the application now, and
3715 the idle is shown on screen.
3717 * Added silc_client_command_reply_identify_save to save the
3718 received IDENTIFY entries.
3720 * Do not check for channel private keys in message sending and
3721 reception if the channel does not have the PRIVKEY mode set.
3722 Affected file lib/silclient/client_channel.c.
3724 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3726 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3727 just surfaced after chaning the JOIN procedure.
3729 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Added silc_client_get_clients_by_list to get client entries
3732 from Client ID list, that is returned for example by JOIN
3733 and USERS command replies. The application should use this
3734 function for example when JOIN command reply is received to
3735 resolve the clients already on the channel (library does not
3736 do that anymore as USERS command reply is not used in the JOIN
3737 procedure anymore). Affected files lib/silcclient/silcapi.h and
3738 lib/silcclient/idlist.c.
3740 * JOIN command reply and USERS command reply returns now SilcBuffer
3741 pointers instead of unsigned char pointers when returning
3742 the client list and mode list.
3744 * Added <Client ID> argument to the JOIN command reply, mainly
3745 for the server to identify for which client the command was
3746 originally sent. Updated protocol specs accordingly.
3748 * Added SilcDlist private_key pointer to the SilcChannelEntry
3749 in the client to support the channel private keys. Affected
3750 file is lib/silcclient/idlist.h.
3752 * Added SilcChannelPrivateKey argument to the function
3753 silc_client_send_channel_message so that application can choose
3754 to use specific private ke if it wants to. If it is not provided,
3755 the normal channel key is used, unless private keys are set.
3756 In this case the first (key that was added first) is used
3757 as the encryption key.
3759 * Implemented the support for channel private key handling.
3760 Implemented the following functions:
3762 silc_client_add_channel_private_key,
3763 silc_client_del_channel_private_keys,
3764 silc_client_del_channel_private_key,
3765 silc_client_list_channel_private_keys and
3766 silc_client_free_channel_private_keys
3768 Affected file lib/silcclient/client_channel.c.
3770 * Added the support for the private keys in the channel message
3771 sending and encryption and in the message reception and
3772 decryption. Affected funtions are
3773 silc_client_send_channel_message and silc_client_channel_message.
3775 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3777 * Added SKE's key verify callback to the client library's
3778 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3780 * Removed the statement that server (or router) must send USERS
3781 command reply when joining to the channel so that the client
3782 knows who are on the channel. Instead, the client list and
3783 client's mode list is now sent in the JOIN command reply to the
3784 client who joined channel. This is better solution.
3786 * Added function silc_server_get_users_on_channel and function
3787 silc_server_save_users_on_channel to the silcd/server.[ch].
3789 * Removed function silc_server_command_send_users from the
3792 * Do not show topic on the client library anymore. The topic is
3793 sent in the command reply notify to the application and the
3794 application must show the topic now.
3796 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Added client searching by nickname hash into the IDENTIFY and
3799 WHOIS commands in the server as they were clearly missing from
3800 them. Affected file is silcd/command.c.
3802 * Fixed a bug in private message receiving in the client library.
3803 The remote ID was freed and it wasn't supposed, now it is
3806 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3808 * Minor fix to the channel payload; allocate the data area, as it
3809 needs to be of specific length.
3811 * If the key agreement port is zero then the operating
3812 system will define the bound port. Affected files are
3813 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3815 * Added new function silc_channel_payload_decrypt into the file
3816 lib/silccore/silcchannel.[ch].
3818 * Moved the channel message etc, check from silc_packet_decrypt
3819 to applications. The library calls now a generic
3820 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3821 when the packet is either normal or special. This was done to
3822 allow more wide range of checking that was not allowed when
3823 the code was in library. Now applications can do virtually any
3824 checks to the packet and return to the library the decision how
3825 the packet should be processed. Affected files are
3826 lib/silccore/silcpacket.[ch].
3828 Added silc_server_packet_decrypt_check to the server and
3829 silc_client_packet_decrypt_check to the client library.
3831 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3832 to send with specified source and destination information.
3834 * Channel message delivery between routers was broken after the
3835 channel key distribution was fixed earlier. The channel key
3836 was used be to distributed to other routers as well which is not
3837 allowed by the protocol. Now this is fixed and channel keys
3838 really are cell specific and the channel message delivery between
3839 routers comply with the protocol specification.
3841 * Fixed various commands in server to check also the global list
3842 for the channel entry and not just the local list. The affected
3843 file silcd/command.c.
3845 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Added assert()s to buffer formatting and unformatting routines
3848 to assert (if --enable-debug) when error occurs. Affected
3849 file: lib/silcutil/silcbuffmt.c.
3851 * Changed to auto-reconnect to check whether the remote host is
3852 router and register the re-connect timeout if it is. It used
3853 to check that whether we are normal server, but router must do
3854 auto-reconnect with another router as well. Affected file
3857 * Removed the [<key len>] option from CMODE command as the cipher
3858 name decides the key length, nowadays. See the defined ciphers
3859 from the protocol specification.
3861 * Added [<hmac>] option to the CMODE command to define the HMAC
3862 for the channel. Added SILC_CMODE_HMAC channel mode.
3864 * Added [<hmac>] option for the JOIN command so that user can
3865 select which HMAC is used to compute the MACs of the channel
3868 * Added Hmac field to the Channel Message Payload. The integrity
3869 of plaintext channel messages are now protected by computing
3870 MAC of the message and attaching the MAC to the payload. The
3871 MAC is encrypted. Now, it is clear that this causes some
3872 overhead to the size of the packet but rationale for this is that
3873 now the receiver can verify whether the channel message decrypted
3874 correctly and also when private keys are set for the channel the
3875 receiver can decrypt the packet with several keys and check from
3876 the MAC which key decrypted the message correctly.
3878 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3879 lib/silccrypt/silccipher.[ch].
3881 * Added silc_hash_len to return the digest length into the
3882 lib/silcrypt/silchash.[ch].
3884 * Rewrote parts of Silc Channel Payload interface in the
3885 lib/silccore/silcchannel.[ch]. The encode function now also
3886 encrypts the packet and parse function decrypts it.
3888 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3890 * Fixed a minor formatting bug in the SKE's key material processing.
3891 It actually might have processed the keys wrong way resulting
3894 * Redefined the mandatory HMAC algorithms and added new algorithms.
3895 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3896 and hmac-md5 truncated to 96 bits. The mandatory is now
3897 hmac-sha1-96. Rest are optional (including the one that used
3898 to be mandatory). Rationale for this is that the truncated HMAC
3899 length is sufficient from security point of view and can actually
3900 make the attack against the HMAC harder. Also, the truncated
3901 HMAC causes less overhead to the packets. See the RFC2104 for
3904 * Added new [hmac] configuration section. The SKE used to use
3905 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3906 is of course wrong. The official names that must be proposed in
3907 the SKE are the ones defined in the protocol specification
3908 (hmac-sha1-96 for example). The user can configure any hmac
3909 using any hash function configured in the [hash] section. At
3910 least, the mandatory must be configured.
3912 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3914 * Added HMAC list to the SKE proposal list. It has now both
3915 hash algorithm list and HMAC list. This makes the protocol
3916 incompatible with previous versions. The SKE now seems to work
3917 the way it is supposed to work, for the first time actually.
3919 * Defined plain Hash algorithms to the protocol specification.
3922 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Implemented support for key agreement packets into the server.
3925 Added functions silc_server_key_agreement and
3926 silc_server_send_key_agreement. Other than these functions,
3927 server has nothing to do with this packet.
3929 * Added support for private message key packets into the server.
3930 Added functions silc_server_private_message_key and
3931 silc_server_send_private_message_key.
3935 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3936 called in the protocol's final callback instead in the END
3937 protocol state. This makes a little more sense and in the same
3938 time in client we can use the same protocol routines for normal
3939 key exchange and to key agreement packet handling as well.
3941 * Added to both client's and server's KE protocol context the
3942 SilcSKEKeyMaterial pointer to save the key material. We will
3943 bring the key material to the protocol's final callback by doing
3944 this. The final callback must free the key material.
3946 * Added SKE's packet_send callback into client's KE protocol
3947 context so that the caller can choose what packet sending function
3948 is used. This way we can use different packet sending when
3949 doing normal SKE when doing key agreement packet handling (in
3950 the key agreement packet handling we do not want to encrypt
3953 * Implemented the responder side of the key agreement routines
3954 in the client. The client can now bind to specified port and
3955 accept incoming key negotiation. The key material is passed
3956 to the application after the protocol is over.
3958 * Implemented the processing of incoming Key Agreement packet
3959 in the client. Added function silc_client_key_agreement to
3962 * Implemented the intiator side of the key agreement routines
3963 in the client. The client can now initiate key agreement with
3964 another remote client. The key material is passed to the
3965 application after the protocol is over.
3967 * Created client_keyagr.c to include all the key agreement
3970 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3971 SILC_TASK_CALLBACK except that it is not static.
3973 * Created client_notify.c and moved the Notify packet handling
3974 from the client.[ch] into that file.
3976 * Created client_prvmsg.c and moved all private message and
3977 private message key routines from the client.[ch] into that file.
3979 * Create client_channel.c and moved all channel message and
3980 channel private key routines from the client.[ch] into that file.
3982 * Changed silc_client_get_client_by_id_resolve to resolve with
3983 WHOIS command instead of IDENTIFY command, in the file
3984 lib/silclient/idlist.c.
3986 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Implemented the SKE's responder side to the Client library.
3990 * When FAILURE is received to the protocol do not trust it
3991 blindly. Register a timeout to wait whether the remote closes
3992 the connection as it should do it, only after that process the
3993 actual failure. This was changed to both client and server.
3995 * Added client_internal.h to include some of the structures
3996 there instead of client.h in lib/silcclient/.
3998 * Added function silc_task_unregister_by_callback to unregister
3999 timeouts by the callback function.
4001 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4003 * Some "Incomplete WHOIS info" errors has been appearing on the
4004 log files. Took away the entry->userinfo check from WHOIS
4005 reply sending. The entry->userinfo is now " " if client did not
4006 provide one. I thought this was fixed earlier but something
4007 is wrong still. Let's see if the error still appears.
4009 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Fixed a minor bug in the login when the channel key is
4012 re-generated in the server. It used to generate the key in
4013 wrong order and thus caused problems in the channel traffic.
4015 * Fixed a minor bug in channel key distsribution after
4016 KICK command. The key was not sent to the router even though
4019 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Added silc_ske_process_key_material_data as generic routine
4022 to process any key material as the SILC protocol dictates. The
4023 function is used by the actual SKE library but can be used by
4024 applications as well. This relates to the private message keys
4025 and the channel private keys since they must be processed the
4026 same way the normal SILC session keys. The protocol dictates
4027 this. Affected files: lib/silcske/silcske.[ch].
4029 Added also silc_ske_free_key_material to free the
4030 SilcSKEKeyMaterial structure.
4032 * Defined silc_cipher_set_key function to set the key for
4033 cipher without using the object's method function. The affected
4034 files: lib/silccrypt/silccipher.[ch].
4036 * Implemented silc silc_client_add_private_message_key,
4037 silc_client_add_private_message_key_ske,
4038 silc_client_del_private_message_key,
4039 silc_client_list_private_message_keys and
4040 silc_client_free_private_message_keys functions in the
4043 Added functions silc_client_send_private_message_key to send
4044 the Private Message Key payload and silc_client_private_message_key
4045 to handle incoming Private Message Key payload.
4047 * Added Cipher field to the Private Message Key payload to set
4048 the cipher to be used. If ignored, the default cipher defined
4049 in the SILC protocol (aes-256-cbc) is used.
4051 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * Removed lib/silcclient/ops.h file.
4055 Redefined parts of the SILC Client Library API. Created new
4056 file silcapi.h that deprecates the ops.h file and defines the
4057 published Client Library API. Defined also private message key
4058 API and channel private key API into the file.
4060 This is the file that the application must include from the
4061 SILC Client Library. Other files need not be included by
4062 the application anymore.
4064 * Added new key_agreement client operation callback and also
4065 defined the Key Agreement library API for the application.
4067 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
4070 is used by clients to request key negotiation between another
4071 client in the SILC network. If the negotiation is started it
4072 is performed using the SKE protocol. The result of the
4073 negotiation, the secret key material, can be used for example
4074 as private message key.
4076 Implemented the Key Agreement payload into the files
4077 lib/silccore/silauth.[ch].
4079 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4081 * Redefined ciphers for the SILC protocol. Added some new ciphers
4082 and defined the key lengths for the algorithms. Changed the
4083 code accordingly. The default key length is now 256 bits.
4085 * Fixed SKE key distribution function silc_ske_process_key_material
4086 when the key length is more than 128 bits. The default key
4087 length in SILC is now 256 bits.
4089 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
4090 to indicate unsupported algorithm.
4092 * Renamed rijndael.c to aes.c and all functions as well.
4094 * Fixed a long standing channel key setting bug in client library.
4095 Weird that it has never surfaced before.
4097 * Fixed bug in channel deletion. If the entire channel is removed
4098 then it must also delete the references of the channel entry
4099 from the client's channel list as the client's channel entry and
4100 the channel's client entry share same memory.
4102 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Implemented CONNECT and SHUTDOWN commands in the client.
4106 * Implemented CLOSE command to the client.
4108 * Added the function silc_idlist_find_server_by_name into the
4109 files silcd/idlist.[ch].
4111 Added the function silc_idlist_find_server_by_conn into the
4112 files silcd/idlist.[ch].
4114 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * DIE command was renamed to SHUTDOWN. Updated the both code
4119 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
4120 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
4122 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
4125 * Added function silc_server_create_connection function to create
4126 connection to remote router. My server implementation actually
4127 does not allow router to connect to normal server (it expects
4128 that normal server always initiates the connection to the router)
4129 so the CONNECT command is only good for connecting to another
4132 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
4135 or some other client was kicked from the channel.
4137 Implemented the handling of the notify type to both client
4140 Implemented silc_server_send_notify_kicked to send the KICKED
4141 notify. It is used to send it to the server's primary router.
4143 * Implemented the KICK command into server and client.
4145 * Added `query' argument to the silc_idlist_get_client function
4146 to indicate whether to query the client from server or not if
4149 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
4150 to indicate that the client is not channel founder.
4154 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4156 * Removed the rng context from SilcPacketContext structure and
4157 changed that the packet routine uses the Global RNG API.
4159 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Added support for quit message that client can "leave" on the
4162 channel when it quits the SILC. It is ditributed inside the
4163 SILC_NOTIFY_TYPE_SIGNOFF notify type.
4165 Added silc_server_free_client_data that will take the
4166 signoff message as argument.
4168 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
4170 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Updated parts of the protocol specification to keep it up
4175 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
4178 payloads in one packet.
4180 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
4181 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
4182 use now the new List flag.
4184 * Also deprecated the following packet types: REPLACE_ID,
4185 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
4187 * Added list support for Notify packet in server.
4189 * Added silc_server_send_notify_channel_change to send the
4190 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
4191 the silc_server_send_replace_id.
4193 * Added silc_server_send_notify_nick_change to send the
4194 NICK_CHANGE notify type. Deprecates the function
4195 silc_server_send_replace_id.
4197 * Added silc_server_send_notify_join to send the JOIN notify type.
4198 Deprecates the function silc_server_send_new_channel_user.
4200 * Added silc_server_send_notify_leave to send LEAVE notify type.
4201 Deprecates the function silc_server_send_remove_channel_user.
4203 * Added silc_server_send_notify_cmode and
4204 silc_server_send_notify_cumode to send CMODE and CUMODE notify
4205 types. Deprecates the silc_server_send_set_mode function.
4207 * Added SERVER_SIGNOFF notify type to indicate that server has
4208 quit. This means that all clients on the channel from that
4209 server will drop. This can be also used when netsplit happens.
4211 Deprecated REMOVE_ID packet type since it is not needed anymore
4214 Added silc_server_send_notify_server_signoff to send the
4215 SERVER_SIGNOFF notify type. Deprecates the function
4216 silc_server_send_remove_id.
4218 Added also silc_server_send_notify_signoff to send the
4219 SIGNOFF notify type.
4221 * Employed the PKCS #1. It is the mandatory way to do RSA in the
4222 SILC protocol from this day on. Changed the protocol
4223 specification as well.
4225 * Added silc_server_send_notify_topic_set to send TOPIC_SET
4226 notify type. It is used between routers to notify about
4227 topic changes on a channel.
4229 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
4232 * Partly updated the protocol specification to comply with the
4233 changes now made. It is still though a bit outdated.
4235 * The JOIN notify type now takes one extra argument <Channel ID>.
4236 The packet used to be destined to the channel but now the
4237 JOIN type may be sent as list thus it is impossible to
4238 destine it to any specific channel. By adding this argument
4239 it is again possible.
4241 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Added CREDITS file. The CHANGES and CREDITS file will appear
4244 in the distribution as well.
4246 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4248 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
4249 types in the server's silcd/packet_receive.c.
4251 * Implemented CMODE and CUMODE to work in router environment.
4253 * Fixed minor encoding and decoding buglet from the
4254 lib/silccore/silcmode.c.
4256 * Fixed buffer overflow from lib/silcclient/command.c in USERS
4259 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
4261 * Changed all SilcConfigServer* and silc_config_server* to
4262 SilcServerConfig* and silc_server_config*, respectively.
4265 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Associated the ID (client or server ID) to the Authentication
4268 Payload to avoid any possibility of forging. Updated the
4269 protocol specification and the code accordingly.
4271 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * The RSA key length is now save to the RsaKey context in the
4274 key generation process in lib/silccrypt/rsa.c. The key length
4275 is now used to figure out the maximum size of the block allowed
4276 to be encrypted/signed.
4278 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
4279 is equivalent to the silc_mp_mp2bin but does not allocate any
4282 * Changed silc_mp_mp2bin API to take length argument. If it is
4283 non-zero then the buffer is allocated that large. If zero, then
4284 the size is approximated using silc_mp_sizeinbase, which however
4287 * Created Global RNG API which is global RNG that application can
4288 initialize. After initializing, any routine anywhere in the
4289 code (including library) can use RNG without allocating a new
4290 RNG object. This was done to allow this sort of use of the
4291 RNG in code that has no chance to allocate RNG object. All
4292 applications currently allocate this and many routines in the
4293 library use this. Affected file lib/silccrypt/silcrng.[ch].
4295 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
4296 it to use the Global RNG API.
4298 * Defined Authentication Payload into protocol specification that
4299 is used during SILC session to authenticate entities. It is
4300 used for example by client to authenticate itself to the server
4301 to obtain server operator privileges.
4303 Implemented this payload into the lib/silccore/silcauth.[ch].
4304 Implemented also routines for public key based authentication
4305 as the new protocol specification dictates.
4307 Moved definitions of different authentication methods from
4308 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
4310 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
4311 silc_pkcs_verify and silc_pkcs_sign_with_hash and
4312 silc_pkcs_verify_with_hash functions into the file
4313 lib/silccrypt/silcpkcs.[ch].
4315 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * The client entry's userinfo pointer must be always valid.
4318 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
4319 will fail since it requires the userinfo. Now, the userinfo
4320 is allocated as "" if actual userinfo does not exist. Actually,
4321 it must exist and it is totally Ok to drop client connections
4322 that does not announce the userinfo. However, we will make
4323 this workaround for now.
4325 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
4326 to return the remote port by socket.
4328 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
4331 SILC_SERVER_PENDING_EXEC and added an new macro
4332 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
4333 data or when error occurs while processing the pending command.
4335 Added new argument `destructor' into silc_server_command_pending
4336 and to the SilcServerCommandPending object. This destructor is
4337 now called after calling the pending callback or if error occurs
4338 immediately. If error occurs the actual pending callback won't
4339 be called at all - only the destructor. The destructor may be
4340 NULL if destructor is not needed.
4342 All this applies for client library code as well. Similar
4343 changes were made there as well for the pending commands.
4345 In the client, the application must now allocate the
4346 SilcClientCommandContext with the silc_client_command_alloc
4349 * Added reference counter to the SilcServerCommandContext. Added
4350 function silc_server_command_alloc and silc_server_command_dup
4353 Same type of functions added to the client library for the same
4356 * Removed the cmd_ident from IDListData away since it is now
4357 global for all connections. It is the command identifier used
4358 in command sending and with pending commands. The affected file
4361 * Added reference counter to the SilcSocketConnection objecet to
4362 indicate the usage count of the object. The object won't be
4363 freed untill the reference counter hits zero. Currently only
4364 server uses this, and client ignores it. The client must be
4365 set to use this too later. The affected files are
4366 lib/silccore/silcsockconn.[ch]. Added also the function
4367 silc_socket_dup to increase the reference counter.
4369 This was mainly added because it is possible that the socket
4370 is removed underneath of pending command or other async
4371 operation. Now it won't be free'd and proper DISCONNECTING
4372 flags, etc. can be set to avoid sending data to connection that
4373 is not valid anymore.
4375 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
4376 the connection. After that it sets SILC_SET_DISCONNECTED.
4377 It is, however, possible that the socket data is not still freed.
4378 The silc_server_packet_process now checks that data is not
4379 read or written to connection that is DISCONNECTED. The socket
4380 get's freed when the reference counter hits zero.
4382 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4384 * Changed the client operation API: channel_message operation's
4385 `sender' is now the client entry of the sender, not the nickname
4386 and the `channel' is the channel entry, not the channel name.
4388 In the private_message operation the `sender' is now also the
4389 client entry of the sender not the nickname.
4391 Affected file is lib/silcclient/ops.h and all applications
4392 using the client operations.
4394 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Moved the calling of ops->connect() from connect_to_server_final
4397 into receive_new_id functin since that is the point when the
4398 client is actually allowed to send traffic to network. The
4399 affected file is lib/silcclient/client.c.
4401 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
4404 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
4405 (if needs broadcasting) instead of broadcasting the packets one
4406 by one which would make a burst in the network traffic.
4408 * Added `broadcast' argument to the functions in silcd/server.[ch]
4409 silc_server_create_new_channel[_with_id] to indicate whether
4410 to send New Channel packet to primary router.
4412 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Added new function into the silcd/server.[ch] files:
4415 silc_server_create_new_channel_with_id to create new channel with
4416 already existing Channel ID.
4418 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
4419 lib/silccore/silcpacket.h. This packet is used t send list of
4420 Set Mode payloads inside one packet. Server uses this to set
4421 the modes for the channels and clients on those channels, that it
4422 announced to the router when it connected to it. The protocol
4423 specification has been updated accordingly.
4425 * The silc_server_new_channel did not handle the packet coming
4426 from normal server as it normally does not send that. However,
4427 when it announces its channels it does send it. Implemented
4428 the support for that.
4430 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
4431 into the file lib/silccore/id.h.
4433 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Fixed memory leaks in the functions silc_idlist_del_client,
4436 silc_idlist_del_channel and silc_idlist_del_server in the file
4437 silcd/idlist.c. All of those leaked like a sieve.
4439 * Fixed some small memory leaks in the client's function
4440 silc_client_notify_by_server.
4442 * Added functions into silcd/server.c: silc_server_announce_clients,
4443 silc_server_announce_channels and silc_server_announce_server.
4444 These functions are used by normal and router server to announce
4445 to its primary router about clients, channels and servers (when
4446 router) that we own. This is done after we've connected to the
4449 These functions effectively implements the following packet types:
4450 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
4451 and SILC_PACKET_NEW_ID_LIST.
4453 * Added new functions into the silcd/packet_receive.[ch]:
4454 silc_server_new_id_list, silc_server_new_channel_list and
4455 silc_server_new_channel_user_list to handle the incoming
4456 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
4458 * Added support of changing Channel ID in the function
4459 silc_server_replace_id. If the server that announces a channel
4460 to the router already exists in the router (with same name but
4461 with different Channel ID), router is responsible to send
4462 Replace ID packet to the server and force the server to change
4463 the Channel ID to the one router has.
4465 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
4466 client that the Channel ID has been changed by the router. The
4467 normal server sends this to the client. Client must start using
4468 the new Channel ID as the channel's ID.
4470 Implemented handling of this new type into lib/silcclient/client.c
4471 into the function silc_client_notify_by_server.
4473 * Added new function silc_idlist_replace_channel_id into the files
4474 silcd/idlist.[ch] to replace the Channel ID.
4476 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Call silc_server_command_identify_check always when processing
4479 the IDENTIFY command in silcd/command.c
4481 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
4484 send keepalive packets. The packet can be sent by clients,
4485 servers and routers.
4487 Added function silc_socket_set_heartbeat into the file
4488 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
4489 If not set, the heartbeat is not performed. The actual
4490 heartbeat is implemented in the low level socket connection
4491 library. However, application is responsible of actually
4494 Added silc_server_send_heartbeat to send the actual heartbeat
4495 packet into silcd/packet_send.[ch]. Server now performs
4496 keepalive with all connections.
4498 * Added silc_task_get_first function into lib/silcutil/silctask.c
4499 to return the timeout task with shortest timeout. There was a bug
4500 in task unregistration that caused problems. TODO has been
4501 updated to include that task system must be rewritten.
4503 * The client library will now resolve the client information when
4504 receiving JOIN notify from server for client that we know but
4505 have incomplete information.
4507 * Rewrote parts of silc_server_remove_from_channels and
4508 silc_server_remove_from_one_channel as they did not remove the
4509 channel in some circumstances even though they should've.
4511 * Encryption problem encountered in server:
4513 The LEAVE command used to send the Channel Key packet to the
4514 router immediately after generating it. However, the code
4515 had earlier sent Remove Channel user packet but not immediately,
4516 ie. it was put to queue. The order of packets in the router
4517 was that Channel Key packet was first and Remove Channel User
4518 packet was second, even though they were encrypted in the
4519 reverse order. For this reason, MAC check failed. Now, this
4520 is fixed by not sending the Channel Key packet immediately but
4521 putting it to queue. However, this is more fundamental problem:
4522 packets that are in queue should actually not be encrypted
4523 because packets that are sent immediately gets encrypted
4524 actually with wrong IV (and thus MAC check fails). So, packets
4525 that are in queue should be encrypted when they are sent to
4526 the wire and not when they put to the queue.
4528 However, the problem is that the current system has not been
4529 designed to work that way. Instead, the packet is encrypted
4530 as soon as possible and left to the queue. The queue is then
4531 just purged into wire. There won't be any fixes for this
4532 any time soon. So, the current semantic for packet sending
4535 o If you send packet to remote host and do not force the send
4536 (the packet will be in queue) then all subsequent packets to the
4537 same remote host must also be put to the queue. Only after the
4538 queue has been purged is it safe again to force the packet
4541 o If you send all packets immediately then it safe to send
4542 any of subsequent packets through the queue, however, after
4543 the first packet is put to queue then any subsequent packets
4544 must also be put to the queue.
4546 Follow these rules and everything works fine.
4548 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added new function silc_server_remove_clients_by_server to
4551 remove all client entries from ID list when the server connection
4552 is lost. In this case it is also important to invalidate all
4553 client entires as they hold the invalid server entry. This
4554 fixes fatal bug when server has lost connection and will reconnect
4557 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4559 * Made some sanity checks to silc_server_daemonise like to check
4560 whether the requested user and group actually exists.
4562 * Added sanity check to SKE's silc_ske_responder_finish to check
4563 that the public and private key actually is valid.
4565 * Invalidate the client's nickname when receiving Replace ID
4566 packet and the Client ID is being replaced. This means that the
4567 server will query the nickname if someone needs it (client)
4570 * Sort the ID Cache in client library when the ID Cache data
4571 has changed (needs sorting).
4573 * Do not allow for SILC client to create several connections to
4574 several servers. The client does not support windows right now
4575 and generating multiple connections causes weird behaviour.
4577 Irssi-silc client does support windows and can handle several
4578 connections without problems, see: www.irssi.org and SILC plugin.
4580 * Fixed some places where client was added to the IDList. The
4581 rule of thumb is following (in order to get everything right):
4582 If the client is directly connected local client then the
4583 `connection' argument must be set and `router' argument must be
4584 NULL to silc_idlist_add_client function. If the client is not
4585 directly connected client then the `router' argument must
4586 bet set and the `connection' argument must be NULL to the
4587 silc_idlist_add_client function.
4589 * The funtion silc_server_packet_send_local_channel actually did
4590 not check whether the client was locally connected or not. It
4591 does that now. Fixed a bug related to LEAVE command.
4593 * Fixed Remove Channel User payload parsing bug in server's
4594 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
4596 * The server's silc_server_save_channel_key now checks also the
4597 global ID list for the channel as it might not be in the local
4598 list. Fixed a bug related to LEAVE command.
4600 * Is this the end of the [<unknown>] buglet that has been lurking
4601 around for a long time? A little for loop fix in server's
4602 silc_server_command_whois_parse that is used by both IDENTIFY
4603 and WHOIS command. At least, this was a clear bug and a cause
4604 of one type of [<unknown>] buglet.
4606 * WHOIS and IDENTIFY commands call the function
4607 silc_server_command_[whois/identify]_check function even if
4608 we are not router server.
4610 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Added --with-gmp configuration option. If set the GMP
4613 is always compiled in the SILC source tree. If not set then
4614 it is checked whether the system has the GMP3 installed. If
4615 it has then the GMP won't be compiled (the system's headers
4616 and library is used), if it doesn't have it then the GMP is
4617 compiled in the SILC source tree.
4619 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Changed RSA private exponent generation to what PKCS #1
4622 suggests. We try to find the smallest possible d by doing
4623 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
4624 not security fix but optimization.
4626 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Added new config entry [Identity] to fork the server and run
4629 it as specific user and group. A patch from Bostik.
4631 * Imported Dotconf configuration library into lib/dotconf.
4632 This will be used to create the SILC configuration files later.
4633 It will appear in the distsribution after this commit.
4635 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4637 * A big code auditing weekend happening. Auditing code for
4638 obvious mistakes, bugs and errors. Also, removing any code
4641 Removed files for being obsolete:
4643 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
4644 inline in the file lib/silcutil/silcbuffer.h)
4646 o lib/silcutil/silcbufutil.c (the header has inline versions)
4648 Changed code to fix possible error conditions:
4650 o The buffer formatting routines now check that the destination
4651 buffer really has enough space to add the data. This applies for
4652 both buffer formatting and unformatting
4653 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
4654 unformatting was changed to accomodate following rules:
4655 XXX_*STRING_ALLOC will allocate space for the data into the pointer
4656 sent to the function while XXX_*STRING will not allocate or copy
4657 the data into the buffer. Instead it sets the pointer from the
4658 buffer into the pointer sent as argument (XXX_*STRING used to
4659 require that the pointer must be allocated already). This change
4660 makes this whole thing a bit more consistent and more optimized
4661 (note that the data returned in the unformatting with XXX_*STRING
4662 must not be freed now). The routines return now -1 on error.
4664 o Tried to find all code that use buffer_format and buffer_unformat
4665 and added return value checking to prevent formatting and
4666 especially unformatting errors and possible subsequent fatal
4669 o Changed ske->x and ske->KEY to mallocated pointers in
4670 lib/silcske/silcske.h. Fixed possible data and memory leak.
4672 o Added return value checking to all *_parse* functions. Fixed
4673 many memory leaks as well.
4675 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4676 so that buffer overflows would not happen. All code now also
4677 checks the return value as it can fail.
4679 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Added reconnection support to server if the normal server looses
4682 its connection to the router (for example if router is rebooted).
4683 The server performs normal reconnection strategy implemented
4684 to the server. Affected file silcd/server.c.
4686 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4688 * Added new packet type SILC_PACKET_SET_MODE that is used to
4689 distribute the information about changed modes (for clients,
4690 channels and clients channel modes) to all routers in the
4691 network. Updated the protocol specification accordingly.
4693 Added functions into silcd/packet_send.c and
4694 silcd/packet_receive.c: silc_server_send_set_mode,
4695 silc_server_set_mode.
4697 Added new files silcmode.[ch] into lib/silccore that implements
4698 the encoding and decoding of Set Mode Payload. Added new type
4699 SilcSetModePayload. Moved the definitions of different modes
4700 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4702 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4704 * Oops, a little mistake in server's connection authentication
4705 protocol. The protocol is not ended with FAILURE but with
4706 SUCCESS if the authentication is Ok. :) Affected file is
4709 * Implemented NICK_CHANGE notify handling in server in the file
4710 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4711 the local clients on the channel. After the changing nickname
4712 in router environment snhould work and the [<unknown>] nickname
4713 should appear no more.
4715 The silc_server_replace_id function that receives the Replace ID
4716 payload now sends the NICK_CHANGE notify type also in the file
4717 silcd/packet_receive.c
4719 * Changed WHOIS and IDENTIFY command to support the maximum amount
4720 of arguments defined in protocol specs (3328 arguments). This
4721 fixed a bug that caused problems when there were more than three
4724 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4726 * Added extra parameter, command identifier, to the
4727 silc_client_send_command so that explicit command identifier
4730 Changed that ID list routines uses specific command identifier
4731 when sending WHOIS/IDENTIFY requests to the server so that they
4732 can be identified when the reply comes back.
4734 Affected files lib/silcclient/command.[ch],
4735 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4737 * Added `sender' argument to silc_server_packet_send_to_channel
4738 to indicaet the sender who originally sent the packet to us
4739 that we are now re-sending. Ignored if NULL. Affected file
4740 silcd/packet_send.[ch].
4742 * Added some server statistics support in silcd/server_internal.h
4743 SilcServerStatistics structure and around the server code. Also
4744 send some nice statistics information when client is connecting
4747 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4749 * Fixed channel ID decoding in server's JOIN command reply in
4750 silcd/command_reply.c
4752 * Fixed braodcasting of replace ID payload to not to send it if
4753 we are standalone server in silcd/packet_receive.c.
4755 * Fixed all channel message sending routines to not to send
4756 packets to clients that has router set, since they are routed
4757 separately in the same function earlier. Affects file
4758 silcd/packet_send.c and all channel packet sending functions.
4760 * In USERS reply, res_argv[i] are not allocated, the table
4761 is allocated. Thus changed that free the table, not its
4764 * In server's whois_check and identify_check if the client is
4765 locally connected do not send any WHOIS commands - they are not
4768 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Fixed some minor bugs in client when sending WHOIS command. The
4771 arguments was in wrong order.
4773 * Removed statis function add_to_channel from server in
4774 silcd/command.c that was previously used with the joining but
4777 * Tested USERS command in router environment successfully with two
4778 routers, two servers and two clients.
4780 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Reorganized the USERS command and command reply in client library
4783 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4784 When the command is given by user we register a pending command
4785 callback that will reprocess the command after the reply has been
4786 received from the server. When reprocessing the packet we then
4787 display the information. Thus, the USERS information is displayed
4788 now in the command callback instead of in the command reply
4789 callback. The processing of the command is same as previously
4790 when server has sent the command reply in the JOINing process.
4792 * Added to USERS command in silcd/command_reply.c to join the client,
4793 we didn't use to know about, to the channel after we've created
4794 a client entry for it. Also, for clienet we did know already still
4795 check whether it is on the channel or not and add it if not.
4797 * Removed silc_server_command_join_notify as the function and its
4800 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4802 * Changed the client's pending command handling to the same as the
4803 server's pending command handling. It is also now possible to
4804 execute command reply functions from other command reply
4805 function as the function callbacks for commands and command
4806 replies are one and same. The pending commands are not static
4807 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4808 in client connection context. Thus, pending commands are server
4809 connection specific as it is convenient.
4811 Changed the function silc_client_command_pending and
4812 silc_client_command_pending_del and added new function
4813 silc_client_command_pending_check. Removed the
4814 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4817 * Added cmd_ident, current command identifier, to the client
4818 connection context in lib/silcclient/client.h to keep track on
4819 command identifiers used in command sending. Client's command reply
4820 function handling now supports the mandatory command identifiers.
4822 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4823 funtions in client to fully support pending command callbacks.
4825 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4826 as one of the arguments to the application in the command reply
4829 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4830 before first releasing SILC but came back. Now it is removed again
4831 and should come back nomore. The FORWARDED flag was used only
4832 by the JOINing procedure by forwarding the command packet to router.
4833 Now, the JOINing procedure has been changed to more generic (due
4834 to various router environment issues) and FORWARDED is not needed
4835 anymore for anything. The protocol specification is yet to be
4838 Now, removed silc_server_packet_forward from server and the flag
4839 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4841 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4843 * Renamed NAMES command to USERS command. The NAMES was named that
4844 due to historical reasons. Now it is renamed. Also, rewrote
4845 parts of the USERS command. The nickname list is not sent anymore
4846 by the server. Only Client ID and mode lists are sent in the USERS
4847 command. Changed this also to the protocol specification.
4849 The client now resolves the names and stuff after it receives
4850 the USERS list from the server when joining to the channel.
4852 * WHOIS and IDENTIFY commands has been changed to support multiple
4853 Client ID's per command. One can now search for multiple users
4854 in the network by sending only one WHOIS or IDENTIFY command.
4855 Changed the code and the protocol specifications.
4857 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4858 uses silc_server_command_whois_parse to parse the request. */
4860 * If normal server, do not parse the WHOIS and IDENTIFY requests
4861 before sending it to the router. Saves some time.
4863 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Fixed JOIN command on client library. Wrong number of arguments
4866 used to crash the client.
4868 * Added silc_server_channel_has_global function to check whether
4869 channel has global users or not.
4871 * Added silc_server_channel_has_local function to check whether channel
4872 has locally connected clients on the channel.
4874 * The silc_server_remove_from_one_channel now checks whether the
4875 channel has global users or not after given client was removed from
4876 the channel. It also checks whether the channel has local clients
4877 on the channel anymore. If it does not have then the channel entry
4878 is removed as it is not needed anymore.
4880 * The silc_server_notify now checks on JOIN notify whether the joining
4881 client is one of locally connected or global. If it is global then
4882 the channel has now global users on the channel and that is marked
4883 to the channel entry. Also, it now saves the global client to
4884 global list who is joining and JOINs it to the channel. This is
4885 for normal server, that is.
4887 Changed silc_server_send_notify_on_channel,
4888 silc_server_packet_relay_to_channel and
4889 silc_server_packet_send_to_channel check if we are normal server
4890 and client has router set (ie. global client) do not send the
4891 message to that client, as it is already routed to our router.
4893 * Implemented LEAVE notify type handling in silc_server_notify
4896 * Tested LEAVE command in router environment successfully. Tested
4897 with two routers, two servers and two clients.
4901 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4903 * Implemented SIGNOFF notify type handling in silc_server_notify
4906 * silc_server_remove_id now removes the client entry from all channels
4907 it has joined and thusly sends SIGNOFF notify type.
4909 * Rewrote the NAMES list generation in server by removing two excess
4910 loops. The lists are created now inside one loop.
4912 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * silc_server_remove_channel_user checks now also global list
4915 for channel and client.
4917 * silc_server_new_channel_user checks now both local and global
4918 list for channel and client. Fixed a bug in client id decoding.
4919 Used to decode wrong buffer.
4921 * silc_server_channel_message checks now both local and global
4922 list for channel entry.
4924 * Tested channel joining (hence JOIN) in router environment
4925 successfully. Tested with two routers, two servers and two
4928 * Tested channel message sending in router environment successfully.
4930 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Added silc_server_save_channel_key into server.[ch] to save the
4933 received channel key in Channel Key payload processing. It is
4934 also used in JOIN command reply handling.
4936 Equivalent function silc_client_save_channel_key added into
4937 client.[ch] into client library.
4939 * Changed JOIN command reply to send information whether the channel
4940 was created or not (is existing already) and the channel key
4941 payload. Changed protocol specs accordingly.
4943 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4944 the request was sent by ID and not by nickname. Crashed on
4947 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4950 now correctly save the received data.
4952 * silc_server_free_sock_user_data now notifies routers in the
4953 network about entities leaving the network.
4955 At the same time implemented functions silc_server_remove_id
4956 and silc_server_send_remove_id to receive and send REMOVE_ID
4957 packets. The packet is used to notify routers in the network
4958 about leaving entities. The ID removed will become invalid in
4961 * Added function silc_idlist_del_server into server. Removes and
4962 free's server entry from ID list.
4964 * silc_server_private_message function now checks, if we are router,
4965 that the destination ID really is valid ID, naturally.
4967 * In router when NEW_ID packet is received (for new client) the
4968 hash of the Client ID is saved in the ID Cache but the
4969 client->nickname is set to NULL, instead of putting the hash
4972 IDENTIFY command now also checks that client->nickname must be
4973 valid. If it is not if will request the data from the server who
4974 owns the client. Added new function
4975 silc_server_command_identify_check.
4977 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4978 to set the command to already allocated Command Payload.
4980 * Tested private message sending in router environment with two
4981 routers, two servers and two clients. Fixed minor bugs and now
4984 * Fixed segfault from client's NAMES command. Used to crash if
4987 * Forwarded packets must not be routed even if it is not destined
4988 to the receiver. Changed server code comply with this.
4990 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4992 * Added `require_reverse_mapping' boolean value to ServerParams
4993 structure. If TRUE (not default) the server will require that
4994 the connecting host has fully qualified domain name.
4996 If the reverse mapping is not required and hostname could not be
4997 found the IP address is used as hostname.
4999 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5001 * Implemented version string checking to both client and server.
5002 The check is incomplete currently due to the abnormal version
5003 strings used in development version of SILC.
5005 * Changed all command functions in server to use the new
5008 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Changed char *data to unsigned char *data in ID Cache system to
5011 support binary data as ID Cache data. Changed code to support
5012 binary data in lib/silccore/idcache.c.
5014 * Renamed silc_server_packet_relay_command_reply to
5015 silc_server_command_reply as it is normal packet receiving
5016 function. Rewrote the function to accept command replys for
5017 servers and not only for clients.
5019 * Mark remote router always as registered server if we are connecting
5020 to it. Otherwise, commands sent by the router to us are ignored.
5022 * All ID List find routines now returns the ID Cache Entry pointer
5023 as well if requested.
5025 * WHOIS command works now in router environment, tested with two
5026 routers, two servers and two clients.
5028 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
5029 in router environment (as it is almost equivalent to WHOIS) but
5030 hasn't been tested thoroughly. Added new functions:
5032 silc_server_command_identify_parse
5033 silc_server_command_identify_send_reply
5034 silc_server_command_identify_from_client
5035 silc_server_command_identify_from_server
5037 * Disabled route cache adding because adding two different ID's with
5038 same IP replaces the old cache entry thus giving wrong route.
5039 The entry->router->connection is always the fastest route anyway
5040 so route cache may not be needed. Of course, new routes maybe
5041 established after receiving the ID when the entry->router->connection
5042 might not be anymore the most optimal.
5044 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Add route cache for received ID for fast routing.
5048 * Added silc_server_packet_route to route received packet on router
5049 that is not destined to us.
5051 * Renamed silc_server_get_route to silc_server_route_get.
5053 * Added id_string and id_string_len fields into SilcServer to
5054 include encoded ServerID for fast comparing without excess
5055 encoding of the ID's.
5057 * Cleaned up WHOIS command on server side. Added following static
5060 silc_server_command_whois_parse
5061 silc_server_command_whois_check
5062 silc_server_command_whois_send_reply
5063 silc_server_command_whois_from_client
5064 silc_server_command_whois_from_server
5066 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
5067 arguments in command replies. All command functions should be
5068 updated to use this macro.
5070 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * Minor typo fixes on command reply handling on server.
5074 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5076 * Added silc_server_command_add_to_channel internal routine to add
5077 the client to the channel after router has created the channel and
5078 sent command reply to the server.
5080 * Added generic silc_server_send_command to send any command from
5083 * Use static buffer with ID rendering instead of duplicating data.
5085 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Fixed a channel user mode bug when joining to a channel server gave
5088 everybody channel founder rights, oops.
5090 * We mark ourselves as the router of the incoming server connection
5091 if we are router ourselves. This way we can check in some packet
5092 sending functions whether it is locally connected server. For
5093 incoming router connections we put NULL.
5095 * For router sending packets locally means now always sending the
5096 packet cell wide; to local clients and local servers. For normal
5097 server sending packet locally means sending it to only local
5100 * Fixed the JOIN command to really work in router environment. If the
5101 channel is created it is always created by the router. Router is
5102 also responsible of making the initial joining to the channel,
5103 sending JOIN notify to the sending server and distributing
5104 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
5105 does not exist server doesn't do anything else but forward the
5106 command to the router which performs everything.
5108 * Added silc_server_send_channel_key function to send the Channel Key
5111 * Added silc_server_create_channel_key to create new channel key. The
5112 channel key is now re-generated everytime someone joins or leaves
5113 a channel, as protocol dictates. Note: channel->key_len is the
5116 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Splitted server.[ch] finally. Created now packet_send.[ch] and
5119 packet_receive.[ch] to separate packet sending and receiving
5120 routines. The server.[ch] now includes everything else including
5121 actual packet processing (writing and reading data) and other
5124 Renamed silc_server_private_message_send_internal to
5125 silc_server_send_private_message. The routine is still though
5126 used only to relay private messages as server does not send
5127 private messages itself.
5129 Renamed silc_server_new_channel to silc_server_create_new_channel
5130 and added new function sicl_server_new_channel that handles the
5131 incoming New Channel packet. Added also new sending function
5132 silc_server_send_new_channel to send New Channel Payload.
5134 * Added new function silc_server_notify to process incoming notify
5135 packet to the server/router. Server may then relay the notify
5136 to clients if needed.
5138 * Added new function silc_server_new_channel_user to process incoming
5139 New Channel User packet. Router will redistribute the packet and
5140 send JOIN notify to its local clients and locally connected servers
5141 if needed. Normal server will send JOIN notify to its local client
5142 on same channel when received this packet. Added also corresponding
5143 sending function silc_server_send_new_channel_user to sent the
5146 * Added boolean route argument to send_notif_to_channel and
5147 packet_send_to_channel functions to attempt to route the packet
5148 if it is TRUE and send only locally if it is FALSE.
5150 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * silc_server_replace_id now broadcasts the received replace ID
5153 packet if it is not broadcast packet already. The router must
5154 broadcast to inform other routers about changed ID.
5156 * Added backpointer to server's router into SilcServer context in
5157 silcd/server_internal.h.
5159 * Fixed silc_server_packet_broadcast to send correct broadcast
5162 * The channel key is now distributed to the local client as soon
5163 as it is received from the router (in router environment) so that
5164 no other packet may be sent for the channel until client has
5167 * silc_server_remove_channel_user now broadcasts the received
5168 Remove Channel User packet if it is not broadcast packet already.
5169 The router must broadcast to inform other routers about removed
5172 * Added users field into SilcPacketContext that is a reference count
5173 of the context. One can increase the reference count by calling
5174 silc_packet_context_dup which is now changed to just increase the
5175 reference count instead of duplicating the data. The reference
5176 count is decresed by calling silc_packet_context_free that will
5177 free the data after the reference count hits zero.
5179 For now on the packet context and everything allocated into it
5180 (including the raw packet from network) must be freed by calling
5181 the new silc_packet_context_free function. Added also new function
5182 silc_packet_context_alloc that must be used now to allocate the
5183 context. This also means that if a routine is asynchronous from
5184 silc_[client/server]_packet_parse_type the packet context must
5185 be duplicated by calling silc_packet_context_dup. Otherwise it
5186 gets free'd after silc_[client/server]_packet_parse_type returns.
5187 Also, one must remember that if packet is duplicated then its
5188 reference count must be decresed by calling the free function as
5189 many times as it was duplicated.
5191 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
5192 from both client and server.
5194 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Made joining to a channel working in router environment.
5198 * Cleaned up JOIN command on server side and create function
5199 silc_server_command_join_channel internal routine to make the
5202 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Changed silc_command_pending list to SilcDList. Also, added
5205 `ident' field to SilcServerCommandPending structure to identify
5206 the reply and to call correct callback.
5208 Added silc_server_command_pending_check function to replace the
5209 corresnponding macro. The silc_command_pending list is not
5212 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
5213 to set identifier to previously allocated Command Payload. It
5214 is used to set identifier for command when resending Command
5217 * Added silc_command_payload_encode_payload to encode Command
5218 Payload buffer from SilcCommandPayload structure.
5220 * Added silc_argument_payload_encode_payload to encode Argument
5221 payload buffer from SilcArgumentPayload structure.
5223 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Changed WHOIS command to support router connection on server side.
5226 The whois request is always sent to router unless the server is
5227 standalone server. After server has received the reply from the
5228 router will it send the reply to the client.
5230 * Added silc_server_packet_broadcast into silcd/server.[ch] to
5231 broadcast received broadcast packet. The function is used only
5232 by router. The broadcast packet is always sent to the router's
5235 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
5236 render given ID to printable string, for log files for example.
5238 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Made basic router to router connections working. At least they
5241 can now connect to each other but nothing really works the way
5242 they are supposed - yet.
5244 * Added new initiator token to RouterConnection configuration
5245 file in silcd/serverconfig.[ch]. It is used to tell whether we
5246 are the initiator to the remote router or whether we'll expect
5247 the other end to connect.
5249 * Moved registering of listener task to silc_server_init, hence
5250 the server starts listenning as soon as it is run, even if it
5251 does not have connections to other routers. Let's see how well
5254 * Changed default connection retry timeouts for more suitable in
5257 * Removed cipher and such arguments from silc_idlist_add_client
5258 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
5259 Added new function silc_idlist_add_data to add the keys and stuff
5262 * Added SilcIDListData structure and added it to SilcClientEntry
5263 and SilcServerEntry as their first field in the structure. This
5264 way we can explicitly cast the ID entries to the SilcIDListData
5265 structure and get common data for the entries. In past, we had
5266 to first check what type of connection it is and then cast it to
5267 correct ID entry type. Now, we can directly cast the opaque
5268 pointer to the SilcIDListData (no matter what ID entry it actually
5269 is) and get the data needed.
5271 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Wow, found a bug in scheduler. The scheduler uninitialized itself
5274 in some circumstances even if threre were timeout tasks, though not
5275 IO tasks, but tasks anyway. Now fixed.
5277 * Defined SilcServerConnection structure to hold connection specific
5278 stuff about directly connected servers and routers. The definition
5279 is currently in silcd/server_internal.h. I thought about having
5280 a bit more important role fro this struct but for now it is used
5281 only when connecting to other server (or router actually).
5283 * Added connecting retry support in server when connecting to
5284 router(s). The retry feature implement exponential backoff
5285 algorithm. Also, added SilcServerParams structure to hold default
5286 parameters for server. For now, it include these retry settings
5287 and are hard coded. After server is moded to be as Silc Server
5288 Library this structure will be more important.
5290 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Changed client librarys channel->clients table to SilcList and
5293 changed code accordingly.
5295 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5297 * Changed client's channel table to SilcList and changed code
5298 accordingly. Also changed SilcChannelClientEntry to include back-
5299 pointer to the channel so that client entry can use that structure
5300 as list as well and we have fast cross-reference to the channel.
5301 This change dramatically decreased the complexity of channel
5302 handling with client entry and vice versa (removed one extra
5303 loop when searching for channel entry from many functions).
5305 * Changed server->sim from table to SilcDList and changed code
5308 * NAMES command can now be used from user interface. It will show
5309 the user list on the channel, neatly.
5311 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
5312 Code now saves realname of the user if it becomes available.
5314 * Renamed configure.in to configure.in.pre and made ./prepare
5315 script to automatically add correct version string to
5316 configure.in which it creates from configure.in.pre.
5318 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * NAMES command reply now shows users mode with the nickname when
5323 * Moved silc_client_ch[u]mode[_char] functions from
5324 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
5325 place sucks, they are utility functions and should be in some
5328 * Fixed some unsigned int's to unsigned short's. Patch by cras.
5330 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
5333 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Added TRQ (efficient deque and list library) into lib/trq. This is
5338 a very good list library that is currently used in the SILC. Defined
5339 SilcList API over the library because I didn't like the API very
5340 much. See lib/trq/silclist.h for the API and examples of how to
5341 use the API. Fixed various places in the code to use the new
5342 SilcList API. The SilcList is meant for lists that has a structure
5343 already defined as a list. It is not suitable to add just some
5344 context to the list (in TRQ, the context is the list actually).
5346 So, I defined SilcDList that can be used for the purpose where
5347 predefined list structure does not exit. This can be used as
5348 such list. Now some context just can be added to the SilcDList.
5349 Currently this list is not used in the SILC just yet, though there
5350 are a lot places where this can replace dynamically allocated
5351 tables and I will fix these places, later, to use SilcDList.
5352 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
5353 and use TRQ internally).
5355 Also fixed some annoying warning messages that the original TRQ
5356 code generated. Also minor changes to TRQ's Makefile.in.
5358 * Added support for querying by Client ID to both WHOIS and
5359 IDENTIFY commands into server, as required by the protocol.
5361 * Removed method function pointers from SilcBuffer structure. They
5362 weren't used to anything and just increased the context size for
5363 no good reason. This change also made silc_buffer_alloc and
5364 silc_buffer_free functions inline functions.
5366 * Disabled command flooding detection support until it's fixed so
5367 that it accepts commands in but does not execute them more than once
5370 * Added silc_net_localhost(), to return local hostname, into
5371 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
5372 that must be initialized before calling silc_client_init.
5374 * Added new function: silc_server_send_notify_on_channels to send
5375 notify messages to all channels client has joined. It is assured
5376 that the message is sent only once per client.
5378 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
5379 lib/silcutil/silcutil.[ch] as silc_format function. The new
5380 function is generic and is used by server as well, not only by
5381 the logging routines.
5383 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
5384 the provided version string was not acceptable. Added new function:
5385 silc_ske_check_version into lib/silcske/silcske.h. The function
5386 must be implemented by the application (client or server) and it
5387 does not reside in the SKE library. The function checks the version
5388 string remote end sent.
5390 * Added back pointers (to opaque context and to SilcSocketConnection)
5391 into SilcPacketContext structure into lib/silccore/silcpacket.h.
5393 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
5394 duplicate packet context structure.
5396 * Changed `notify' client operation to send same arguments as client
5397 receives from server except for ID's. ID's are mapped to correct
5398 ID entry and that is returned. Also, if channel entry is not sent
5399 by server but the notify is for channel the channel entry is sent
5400 to application (otherwise application doesn't know that it is for
5401 channel (library gets it from packet's Destination ID)).
5403 * Added silc_client_remove_from_channels into client library to
5404 remove a client from all channels it has joined to. Used when
5405 received SIGNOFF notify from server. Added also new function
5406 silc_client_replace_from_channels to replace old ID entry with
5407 new ID entry on all channels. Used when received NICK_CHANGE
5410 * Fixed ID Cache list handling in silc_idlist_get_client in
5411 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
5412 to get (or query) client by ID.
5414 * Updated TODO list.
5416 * Added connection authentication status message defined by the
5417 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
5418 support for these into the code in client and server side.
5420 * Added generic function silc_client_send_command to send any command
5421 with variable argument list. Application should use this function
5422 to send commands if the command functions provided by the library
5423 does not suite for the application's user interface needs.
5425 * Added new `failure' client operation. Application is notified about
5426 received failure packet if client is executing a protocol. In this
5427 case the protocol's execution has failed.
5429 * Added SKE's end notify to send the SKE_SUCCESS notify message that
5430 is required by the protocol.
5432 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
5433 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
5436 * Added status flag to SilcSKE object to indicate realtime status
5437 of the SKE protocol.
5439 * Application receives now exactly same command reply arguments as
5440 the library receives from server. However, if ID is received the
5441 corresponding ID entry is returned to the application (eg. Client
5442 ID is mapped to correct SilcClientEntry entry and that is returned).
5443 Changed command_reply client operation due to this change.
5445 * Changed all ID's in commands and in command replys as ID Payloads.
5446 Change affected both client and server side codes.
5448 All ID's sent in SILC network (with execption of ID's in SILC
5449 Packet header) are sent in ID Payload to support variable length
5452 * Server now notifies nick changes and notifies all clients on
5453 the channels about the new nickname (about the new Client ID,
5456 * Implemented CMODE command to change channel modes. Supports all
5457 channel modes defined by the protocol specs except ban and invite
5458 lists. (Also, private channel key mode is supported but support for
5459 setting private channel key in client is missing, thus, this mode
5460 has no effect on client side (except that server requires that the
5461 client uses private channel key and normal channel traffic does not
5464 Also, invite mode works per se, but INVITE command does not work
5465 yet correctly, so you can set channel as invite only channel but
5466 inviting clients to the channel does not work (it is yet to be
5467 thought what's the best way to do it).
5469 * Added new command SILC_COMMAND_CUMODE to change user mode on the
5470 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
5471 Implemented CUMODE command to change user's mode on the channel.
5472 Supports all modes defined by the protocol specs.
5474 * Added NAMES command reply to return users modes on the channel.
5476 * Removed unnecessary and slow ciphers from lib/silccrypt.
5478 * Set SO_KEEPALIVE option to connection sockets by default.
5480 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
5482 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
5483 redefined the Notify Payload into protocol specs.
5485 * Added silc_id_payload_parse_id to get ID directly from raw
5488 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
5491 accept searching by Client ID as well.
5493 * Added support for LEAVE and SIGNOFF notify types in client library.
5495 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
5496 to parse ID Payload from raw data.
5498 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Added flags parameter into silc_ske_assemble_security_properties
5501 function in lib/silcske/silcske.[ch].
5503 * Changed notify client operation to fit better for notify messages
5504 sent by server. The notify payload received from server is now
5505 passed to the application (after parsing it to SilcNotifyPayload).
5506 It is application's responsibility to retrieve the arguments
5507 from the payload and show the message the way it wants. The message
5508 sent by server is implementation specific.
5510 * Changed public keys to comply with the protocol specification.
5511 Old public keys are not supported anymore and are not compatible.
5513 * Removed nickname from Channel Payload as the latest draft removed
5514 it. The client must resolve the nickname from the NAMES command
5515 reply received when it joined the channel.
5517 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
5519 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Fixed some errors in protocol specification drafts.
5523 * Created lib/silccore/silcnotify.c to implement Notify Payload
5524 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
5525 generic payloads described by protocol specifications. The file
5526 includes implementations for ID Payload and Argument Payload.
5528 * Changed Command Payload implementation to use the new Argument
5529 Payload. Changed command_xxxx_payload to command_payload_xxxx
5530 to comply with SILC coding conventions.
5532 * Added suppport for Argument Payload handling in Notify Payload
5533 implementation as protocol requires it. Added the new support
5534 into server and client lib as well.
5536 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5538 * Added support for multiple nicknames on same channel. [n] is
5539 added locally to the nickname if there are more than one same
5540 nicknames on the channel.
5542 * Server now sends all nicknames that matched WHOIS request.
5543 Client also shows the list received from server.
5545 * Added TOPIC command to client side. User can now set and show
5546 current topic on channel.
5548 * Added MOTD command to client and server. Also, server sends the
5549 motd when client connects to the server.
5551 * Changed version strings to comply ISO 8601.
5553 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Fixed protocol error handling in client library. It should now
5556 cope even if the SKE fails for some reason.
5558 * Made new protocol specification drafts for submitting to IETF.
5560 * Implemented TOPIC command to server in silcd/command.c.
5562 * Added two new notify types into lib/silccore/silcnotify.h:
5563 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
5564 notify nickname change and topic setting/change on a channel.
5566 * API change of command_reply operation in client library. The
5567 application gets now the status type received from server as well.
5569 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Removed the function just added to lib/silcutil/silcschedule.[ch].
5573 * Cras fixed and optimized the packet handling even further and
5574 it should work now. Minor change to the prototype of function
5575 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
5577 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Added new function into lib/silcutil/silcschedule.[ch]:
5580 silc_schedule_with_fd to select() a specified fd. The function
5581 returns after timeout expires or data arrives or goes. The
5582 function is used by packet routines to wait that all data is
5583 received from network.
5585 * Fixed data reading from network in lib/silccore/silcpacket.c.
5586 The code now assures that all data is read from the fd and then
5587 continues packet processing. This was a bug fix since the code
5588 used to drop some data in some circumstances.
5590 * Added new function into lib/silcclient/client.[ch]:
5591 silc_client_start_key_exchange to start key exchange after
5592 connection has been established to server. The code internally
5593 now uses this funtion but its main purpose was to provide it
5594 for applications that perform their own connecting. After
5595 application has created a connection it merely calls this
5596 function to start the key exchange between client and server.
5597 The library takes care of everything else after that.
5599 Updated also lib/silcclient/README to explain the usage of
5602 * Do not send to application information that connection has
5603 been established. Application gets notified it by connect
5606 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5608 * Applied cras's patch to add silc_schedule_one function. The
5609 function runs scheduler once and returns.
5611 * Fixed the scheduler after cras messed it up. The timeout
5612 handling works now as it's supposed to work.
5614 * Added into lib/silccore/ silcnotify.h to include notify
5615 message types support. Changed silc_server_send_notify*
5616 functions, in server.[ch], to support those new notify types.
5617 Added the support for the notify types into client library,
5618 as well. Added new notify client operation into ops.h in
5621 * Changed silc_server_packet_send_to_channel to send normal
5622 packets instead of just channel message packets. The function
5623 is now used to send the notify packets to channels. It is not
5624 used to send channel message packets anymore, as server never
5627 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
5628 va_arg()s as it seems to require it nowadays. I guess, if SILC
5629 is compiled with older va_arg() the new code should work anyway.
5631 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Splitted core library. Core library (lib/silccore) includes
5634 now only SILC protocol specific core (and common) components.
5635 Created new utility library (lib/silcutil) that includes more
5636 generic purpose stuff. The stuff for util library was taken
5637 from the old core library. This was minor and easy split.
5639 * Created SILC Client Library (lib/silcclient) that includes
5640 implementation of the SILC client without user interface. This
5641 was major move from silc/ directory. The code has been changed
5642 so that it is transparent towards the user interface. The
5643 silc/ directory includes now the same user interface as before
5644 and it uses the new client library. Read lib/silcclient/README.
5645 Basicly, the client library performs everything else related
5646 to SILC except user interface handling. Also, configuration
5647 files are considered to be part of user interface and library
5648 does not handle them.
5650 This change also changed a lot of structures, function naming etc.
5651 Most important change was that SilcClientWindow object was
5652 renamed to SilcClientConnection in the client library. Created
5653 also new file lib/silcclient/ops.h. Also added new files
5654 silc/local_command.[ch] and silc/client_ops.[ch].
5656 All these changes were made to make it easier for user interface
5657 designers to create what ever user interface for the SILC client
5660 It is also expected that the server will be moved to lib
5661 directory as well and SILC Server Library will be created;
5662 sometimes in the future.
5664 * Removed Local commands from lib/silccore/silccommand.h as
5665 they are application specific and new client library does not
5666 handle any of those anymore.
5668 * Several functions moved to lib/silcutil/silcutilc.[ch] from
5669 old client implementation in silc/.
5671 * Added support for callback functions in SILC_LOG_* macros.
5672 Application can now set its own callbacks that will be called
5673 instead of using the default functions that will always print
5674 the debug messages to stderr (or stdout). Also, debugging can
5675 now be disabled by setting silc_debug to FALSE and re-enabled by
5676 setting it to TRUE. Note, that logging will still work even
5677 if debugging is disabled.
5679 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5680 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5681 silc_log_reset_debug_callbacks.
5683 * To enable debugging in silc client one must give now -d
5684 option on command line.
5686 * Changed silc_schedule_init to automatically allocate task queues
5687 if they are not allocated before calling it.
5689 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Added GMP 3.1 into math library.
5693 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5696 a channel in SILC network. The packet is used by servers and
5697 routers to notify other routers that user has left a channel.
5698 This little feature was missing until now. Added the feature
5699 to protocol specification as well.
5701 Added functions: silc_server_send_remove_channel_user and
5702 silc_server_remove_channel_user into server.[ch].
5704 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5705 lib/silccore/silcpacket.h. However, they are not implemented
5708 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Fixed joining to a channel and sending channel messages
5711 between server and router. The channel message sending should
5712 now work inside a cell.
5714 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Fixed the private message sending between server and router.
5717 The private message sending should now work inside a cell.
5719 * Added silc_server_replace_id into server.[ch] to replace
5720 existing ID in the SILC network.
5722 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5723 and silc_idlist_replace_server_id into idlist.[ch] in server.
5725 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed the server to server connections. Server can again now
5728 connect to router. Router to router connections probably does
5731 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Added dynamic protocol registering support. Now protocols can
5734 registered and unregistered on the fly. Patch by cras.
5736 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Added lib/contrib directory to hold routines that some platforms
5739 don't have but are needed by SILC.
5741 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5742 into lin/contrib to provide getopt() and getopt_long() for
5743 those who don't have it.
5745 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Added AWAY command to client. When away message is set and
5748 client receives a private message packet the client automatically
5749 replies to the sender with the away message.
5751 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5752 bug seemed to be the cause of recent problems when compiling
5755 * Added version detection support to SKE protocol specification
5756 and added the new changes to the SKE implementation as well.
5757 There were other minor changes in the SKE protocol as well.
5759 Many changes in lib/silcske/silcske.[ch] and in
5760 lib/silcske/payload.[ch].
5762 * Added ^U functionality, clear input line. Patch from cras.
5764 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Mainly small bugfixes on core library. Fixed some debugging
5767 logging and buffer overflow in silclog.c.
5769 * Updated config.sub and config.guess on the distribution tree.
5771 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Added command lagging support in server. Client may execute
5774 commands now only once in two seconds.
5776 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Optimized packet reception. MAC computation and checking is now
5779 also more optimized. A lot previously duplicated code is now
5780 used as generic by both client and server.
5782 * Fixed key pair generation in clientutil.c
5784 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Added into lib/silccore/silcbufutil.[ch] new function;
5787 silc_buffer_realloc.
5789 * Moved generic packet sending/encryption functions to
5790 lib/silccore/silcpacket.[ch] from client and server. Some
5791 rewriting of the functions.
5793 * Moved all generic packet reception/decryption functions to
5794 lib/silccore/silcpacket.[ch] from client and server. The
5795 packet processing is now much cleaner in both client and server.
5796 These were major changes in both client and server.
5798 * Created many common functions in server to do packet sending.
5799 Previously code were duplicated a lot, this has been removed
5802 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Rewrote major parts of the ID cache system. Don't know
5805 whether it is better now or not but at least the API is more
5808 * Major rewrite on ID cache stuff on client because of the ID
5809 cache API changes. Added idlist.c to client.
5811 * Also major rewrite on ID cache stuff on server as well.
5812 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5813 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5814 in hand, instead they are all put into the ID cache system now.
5815 All server_idlist_* routines uses ID cache now instead of
5816 traversing its own lists (those lists does not exist anymore).
5817 SilcIDList though still exists. Also, SilcXXXEntry's are
5820 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Finally made the SKE implementation compliant to the protocol
5823 specification. All mp integers are now binary encoded as
5824 opposed being HEX encoded.
5826 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5829 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5830 functions: silc_[encode/decode]_pem. Also added function
5831 silc_encode_pem_file to PEM encode with newlines ('\n') for
5834 * SILC public keys are now encoded either PEM or binary. Same
5835 option is for private keys as well. By default private keys
5836 are binary encoded and public keys PEM encoded. Silly HEX
5837 encoding were removed.
5839 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5840 function to create fingerprints.
5842 * Fixed a bug in SHA1; does not change the original data anymore.
5844 * Partly implemented INFO command on client and server side.
5845 Fixed CLEAR command. Changes to SERVER command; show current
5846 server(s) when giving command without arguments. Added
5847 VERSION command to client.
5849 * Added check to server that unregistered connections cannot
5850 execute commands (unless it is specificly allowed).
5852 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5854 * Fixed screen refresh.
5856 * Fixed channel joining bug from client. On some circumstances
5857 client tried to join to a channel it had already joined.
5859 * Added public key verification process into client's protocol.c.
5860 The client now verifies the public key from user and saves
5861 it into ~./silc/serverkeys/ directory.
5863 Added into: clientutil.[ch]: silc_client_verify_server_key.
5865 * Changed SKE protocol's silc_ske_initiator_finish function
5866 to accept callback function that verifies the received public
5867 key. Removed old silc_ske_verify_public_key function.
5869 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5872 silc_pkcs_private_key[_data]_set.
5874 * Made the password and public authentication more cleaner in
5875 server's protocol.c.
5877 * Removed historic and obsolete protocol `channel_auth' from
5878 both client and server.
5880 * Removed wrong way of sending command status messages from
5881 server to client in server's command.c. The old way violated
5882 protocol specification.
5884 Changes to silccore/silccommand.[ch]: removed
5885 silc_command_encode_status_payload -> not needed anymore,
5886 changed silc_command_encode_payload_va to accept extra
5887 argument on variable argument list. The argument type must
5888 now be provided to the function. Also, added new function:
5889 silc_command_encode_reply_payload_va which is same as
5890 normal command_encode_payload_va except command status type
5891 is provided as extra argument.
5893 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added ~./silc directory handling. The directory includes the
5896 public and private keys for the client.
5898 Added silc_client_check_silc_dir, silc_client_create_identifier
5899 and silc_client_load_keys.
5901 * Implemented SILC protocol compliant public key. Added public
5902 and private key saving to and loading from files.
5904 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5905 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5906 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5907 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5908 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5910 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5911 silc_pkcs_load_[public/private]_key.
5913 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added silc_server_get_route (route.[ch]) to get connection
5916 data for the fastest route for given ID.
5918 * Implemented INVITE command on client and server. The command
5919 were re-defined in the SILC Protocol Specification and the
5920 implementation now complies with the specification.
5922 * Implemented PING command on client and server.
5924 * Implemented NAMES command on client and server. The server side
5925 supports currently only normal server not router server yet.
5926 Some changes to NAMES definition in SILC protocol specification.
5928 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Implemented LEAVE command on client and server.
5932 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5933 again. This change was made to the protocol as well. Server
5934 should not violate the protocol specification anymore.
5936 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5938 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5939 was tested. SOCKS4 was not but should work anyway.
