160 another command may attach to the same pending command reply
161 without requiring to resolve the same entry again. Added
162 support for adding multiple pending commands for one
163 command idenfier. Affected files lib/silcclient/command.[ch],
164 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

241 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Redefined the Status Payload to include now two 8 bit fields,
244 instead of one 16 bit field. This now makes it possible to
245 send list of errors. Updated the protocol specs and the code
246 in core library, client library and server. Protocol TODO #1.
247 Affected files are lib/silccore/silccommand.[ch],
248 lib/silcclient/command_reply.[ch], silcd/command.c,

278 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
280 * Added STATS command to the protocol after all, to return
281 various statistical information about the network. It can
282 be used by clients to retrieve statistical information, and
283 servers may use it to to fetch cell and network wide
284 statistics from router. Updated the protocol specs and
285 implemented it to the server. Protocol TODO #16.
286 Affected files are lib/silccore/silccommand, silcd/command.[ch],
287 silcd/command_reply.[ch].
289 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
291 * The LIST command reply in client libary now adds new channel
292 entry if the returned channel doesn't exist yet in cache,
293 and returns the channel entry to the application in the
294 command_reply client operation. Affected file is
295 lib/silcclient/command_reply.c.
297 * Changed the channel message payload's MAC generation to
298 include the IV in the MAC as well. This way all relevant
299 parts of the channel message payload are authenticated also
300 with the channel message MAC (and not only by packet MAC).
301 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
302 Affected file is lib/silccore/silcchannel.c.
304 * Fixed the SKE to save the remote version, since the
305 silc_ske_parse_version mistakenly checked wrong version,
306 after it replaced the start payload. Affected files are

330 need the SilcSocketConnection which should not be visible
331 to application. Affected files are lib/silcclient/client.c
332 and lib/silcclient/silcclient.h.
334 * Rewrote the text for Private Message Key Payload in the
335 protocol specification. Protocol TODO #11.

353 The killer's client entry is now returned to application in
354 the `notify' client operation.
356 * Fixed the Max Argument fields that had too large value set
357 in the protocol specs. Protocol TODO #14.
359 * Added the LEAVE command reply to return the ID of parted
360 channel. Updated protocol specs and implemented it to the
361 client and server. Protocol TODO #15. Affected files are
362 silcd/command.c, lib/silcclient/command_reply.c. The channel
363 entry is now returned to application in the `command_reply'

373 file is silcd/command.c.
375 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
376 generic reply to a generic request (REQUEST flag), and
377 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
378 way. A draft-riikonen-silc-flags-payloads-00.txt is written
379 to define the payload for DATA flag. Added the flags to
380 the implementation. Protocol TODO #9. Affected file is

423 Affected file silcd/protocol.c.
425 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Some client implementations quit network by doing first LEAVE
428 and then immediately SIGNOFF (like Bombyx). We now do check
429 after a short time after LEAVE notify and check whether the
430 client is still valid after LEAVE, and if not we remove it from
431 cache. Affected file is lib/silcclient/client_notify.c.
433 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
435 * Merged version 1.1.4 of zlib. Even if it not currently in use,

459 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
461 * Changed the silc_get_username and silc_get_real_name to
462 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
464 * Fixed the Irssi SILC Client to use the silc_get_username and
465 silc_get_real_name insted of glib routines since the glib
466 routines only corrupt stack. Fixes the Irssi SILC to work in
467 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
469 * Fixed the Irssi to not use g_get_home_dir since it crashes

481 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
483 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
485 * And yet again reverted back the config thing since Johnny
486 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
489 * Fixed memory leaks from config object. Affected files are
490 silcd/serverconfig.[ch].
492 * Added support for adding new connections to the server in rehash.

506 public/private key and removed further checks in the code.
507 Affected files are silcd/serverconfig.[ch], server.c.
509 * Moved functions silc_server_drop() and silc_server_daemonise()
510 from server.c to silcd.c since they are stricly related to
511 the application activity.
513 * Reverted a small part of the automatic ref/unref since
514 it caused a double unref in some situations. Affected
515 files are silcd/silcd.[ch], server.c, serverconfig.c.
517 * Added some .cvsignore files in the lib directory.
519 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Fixed silc_net_gethostbyaddr to correctly resolve by
522 address. Affected file lib/silcutil/silcnet.c.
524 * Fixed the notify relaying to client. The HMAC to be used
525 with relayed packets ws wrong and caused decryption failure
526 at the client end. Affected file is silcd/packet_receive.c.
528 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
530 * Created new branch silc_protocol_1_0_branch.
532 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
534 * Changed the silc_server_config_* routines to be SilcServer
535 independent. They are now officially application specific code
536 and not part of generic server implementation. Affected files
537 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
539 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Added automatic referencing of config context in the
542 silc_server_config_alloc, and automatic unreferencing in the
543 silc_server_config_destroy. Affected files are
544 silcd/serverconfig.[ch], silcd/silcd.c.
546 * Fixed the silc_log_quick handling in the logging routines.
547 It didn't log quickly when it was TRUE. Affected file is
548 lib/silcutil/silclog.c. Also the flush delay was set even
549 if it was 0 in config file. Affected file is
550 silcd/serverconfig.c.
552 * Added support for changing key pair of the server in rehash.
553 Affected file silcd/server.c.
555 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Fixed the TOPIC_SET notify to not cras. It changed the topic
558 too early, before getting the channel entry. Affected file
559 is silcd/packet_receive.c.
561 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
563 * Added functions silc_server_config_[ref/unref], these are used
564 to prevent that the config object is destroyed.
566 No longer directly affect global variables silc_log_quick and
567 silc_log_delay, they are first cached inside the config object
568 and then applied with silc_server_config_setlogfiles().
570 silc_server_config_set_defaults() is now internal to
571 serverconfig.c, there are no reasons to show this internal stuff
574 Affected files are silcd/serverconfig.[ch].
576 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
577 fprintf's to stderr, since some code may be executed again after
578 the server went into the background. Affected files are
581 * Added rehash support. Added function silc_server_rehash() that
582 will perform all the basic tasks of the rehashing procedure.
584 * Added command line option `-x, --hexdump'. This will enable the
585 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
586 The option `--hexdump' implies `--debug'.
588 * Fixed a bad bug in the logging APIs (silcutil library) where
589 the application would crash after calling silc_log_reset_all().
591 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
593 * Fixed the KICKED notify handling in client library to
594 correctly remove the channel and all entries from the
595 channel when I was kicked. This bug crashed the client.
597 Fixed yet another but in KICKED notify handling to remove
598 the kicked client correctly from the channel.
600 Affected file is lib/silcclient/client_notify.c.
602 * Fixed a minor bug in looking up correct client entry
603 in KICKED notify in server. Affected file is
604 silcd/packet_receive.c.
606 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
607 sources correctly to distribution. Fixes --with-gmp option.
609 * Removed the manual rehashing from ID Cache, and changed it
610 to use the SILC Hash Table's auto rehash feature. Affected
611 file is lib/silccore/silcidcache.c.
613 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Fixed a bug in the silc_client_nickname_format function that
616 handles the multiple same nickname formatting. Two clients
617 with same nickname caused problems after the first one left
618 and rejoined. It didn't format the nickname correctly.
619 Affected file is lib/silcclient/idlist.c.
621 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
623 * Don't change the topic if olod topic is same as new one.
624 Affected file is silcd/packet_receive.c.
626 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Added cross-reference support to the SILC Documentation
629 generator. All types across all HTML files are now cross-
630 referenced. Affected files util/robodoc/generator.c and
631 scripts/silcdoc/silcdoc.
633 * Added file lib/silcutil/silctypes.h to include all the
634 arithmetic type definitions and some macros. Removed
635 includes/bitmove.h and moved macros to silctypes.h.
637 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
639 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
641 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Added `type' argument to silc_id_payload_parse_id function which
644 now returns the type of the ID to the sent pointer. Affected
645 file is lib/silccore/silcid.[ch].
647 * Added check for CMODE_CHANGE notify type that mode change is
648 allowed by the sender. Affected file silcd/packet_receive.c.
650 * Added check for CUMODE_CHANGE notify type that mode change is
651 allowed by the sender. Affected file silcd/packet_receive.c.
652 Added the ID type as CUMODE_CHANGE notify type as argument
653 to the `notify' client operation. Affected files are
654 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
656 * Added function silc_client_add_server to the client library.
657 Added support for resolving also channel and server info when
658 received unknown entity in notify packet. Affected files are
659 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
661 * Added function silc_command_get_status to return the command
662 status from the command reply's argument payload. Affected files
663 are lib/silccore/silccommand.[ch].
665 * Added check for KICKED notify type that the kicking is
666 allowed by the client. Affected file silcd/packet_receive.c.
668 * Created function silc_get_input which can be used to get input
669 (echo on or off) from user on command line. Affected files are
670 lib/silcutil/silcutil.[ch].
672 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Optimized silc_server_packet_relay_to_channel function.
675 Added new function silc_channel_message_payload_encrypt which
676 can be called directly if channel message payload needs to
677 be encrypted and is already encoded (no need to call _encode
678 function). Packet relaying is now done by router without any
679 extra memory allocations. Affected files are
680 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
683 * Fixed the INVITE notify handling. It took wrong arguments
684 as invite list and invite delete. Affected file is
685 silcd/packet_receive.c.
687 * Added check for TOPIC_SET notify type that the topic change is
688 allowed by the client. Affected file silcd/packet_receive.c.
690 * Added check for INVITE notify type that inviting is allowed by
691 the client. Affected file silcd/packet_receive.c.
693 * Changed the silc_server_client_on_channel to return the
694 SilcChannelClientEntry as well. Moved the function
695 silc_server_check_cmode_rights to server_util.[ch].
696 Affected files are silcd/server_util.[ch], silcd/command.c.
698 * Added function silc_server_check_umode_rights to check whether
699 changing client's user mode is allowed. Added check for
700 UMODE_CHANGE notify type that the umode change is allowed
701 by the client. Affected files are silcd/server_util.[ch],
702 silcd/packet_receive.c and silcd/command.c.
704 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
707 ID length. It ignored that ID can be IPv6 based as well.
708 Affected file lib/silccore/silcpacket.h.
710 * Fixed the silc_id_id2str and silc_id_str2id to take the
711 IPv6 address offset's into consideration. Affecte file is
712 lib/silccore/silcid.c.
714 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
716 * Fixed the internal Unix scheduler functions to check for
717 NULL context they may receive. The affected file is
718 lib/silcutil/unix/silcunixschedule.c.
720 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
722 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
723 can specify different directory with --home command line
724 parameter. Affected files irssi/src/silc/core/client_ops.c,
727 * SILC-specific commands aren't now executed if the active server
728 isn't of SILC-type, so there won't be problems with having
729 IRC and SILC protocol support in same client. Affected files
730 irssi/src/silc/core/silc-channels.c, silc-servers.c,
733 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
735 * Improved the signal support in SILC Schedule. Added new
736 function silc_schedule_signal_call which is used by application
737 to mark a signal to be called. It is now safe to perform
738 any kind of tasks in signal callbacks since it is guaranteed
739 that the application specified signal callback is called
740 after the signal is over. Affected files are
741 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
743 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Added `name' field to SilcChannelPrivateKey to represent
746 application given name for the key. Moved also the context from
747 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
748 Added the `name' argument also to the function
749 silc_client_add_channel_private_key.
751 Added function silc_client_current_channel_private_key to set the
752 current channel private key in use.
754 Added "change" command to KEY command which can be used to change
755 the current channel private key. Bound the command also to
758 Also affected files lib/silcclient/client_channel.c,
759 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
761 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Added silc_rng_get_byte_fast function in to the
764 lib/silccrypt/silcrng.[ch].
766 * Changed the interface of silc_packet_assemble and the
767 silc_packet_send_prepare. If silc_packet_assmble is now
768 called the application does not call silc_packet_send_prepare
769 because the library will call it automatically. These
770 interfaces now also return a reference to the outgoing buffer
771 which includes the assembled packet, which the application can
772 use to encrypt the packet.
774 Affected files are lib/silccore/silcpacket.[ch],
775 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
776 silcd/packet_send.c, server_backup.c and packet_receive.c.
778 * Fixed a packet sending bug on very high load, where outgoing
779 packet queue wasn't handled correctly and packets got corrupted.
780 Affected files are lib/silcutil/*/silc*sockconn.c,
781 lib/silcclient/client.c and silcd/server.c.
783 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
785 * Added macro SILC_PACKET_DATALEN which can be used during
786 packet assembling to check whether the data to be added to
787 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
788 len is truncated until it fits it.
790 Added checks for maximum length of channel message payload and
791 private message payload also.
793 Added checks for maximum packet length in server and in
796 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
797 lib/silcclient/client.c, lib/silccore/silcchannel.c and
798 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
799 lib/silcclient/client_prvmsg.c.
801 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
803 * Added silc_server_packet_queue_purge call to the
804 silc_server_disconnect_remote to assure that all data in the
805 queue before disconnecting is sent to the network. Affected
808 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Added the deleting of server's own ID cache entry to the
811 silc_server_free function. Free also everything else that
812 has been allocated in silc_server_init. The affected file
815 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
817 * Added functions silc_parse_version_string, silc_version_to_num,
818 and silc_ske_parse_version to parse SILC protocol style version
819 strings. Affected files lib/silcutil/silcutil.[ch] and
820 lib/silcske/silcske.[ch].
822 * Added new configuration params: version_protocol, version_software
823 and version_software_vendor to specify what version the remote
824 host must at least be to be able to connect to server. The vendor
825 string can be regex matched too. Added new function
826 silc_server_connection_allowed to check maximum number of allowed
827 connections, and allowed versions for incoming connections.
828 Affected files are silcd/server.c, server_util.[ch] and
831 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
833 * Added preliminary support for signals in scheduler. The
834 signals we care about are now blocked always when the scheduler
835 is locked. This way we can synchronise the use of signal with
836 scheduler. It is guaranteed that when signal occurs the scheduler
837 is not locked, and thus new tasks can be safely added to the
840 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
841 to silc_schedule_internal_init and silc_schedule_internal_uninit.
842 Added new platform specific routines
843 silc_schedule_internal_signals_[un]block and
844 silc_schedule_internal_signal_[un]register.
846 Added new functions to SILC Schedule API:
847 silc_schedule_signal_[un]register. Each signal that application
848 is going to use should be registered to the scheduler.
850 Affected files are lib/silcutil/silcschedule.[ch],
851 lib/silcutil/*/silc*schedule.c.
853 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
855 * Check for unauthenticated client and server in the
856 silc_server_new_client and silc_server_new_server functions.
857 Affected file silcd/packet_receive.c.
859 * Added function silc_string_is_ascii to check whether given
860 string is 7-bit ASCII string. Affected files are
861 lib/silcutil/silcutil.[ch].
863 * Added function silc_id_is_valid_server_id into the
864 silcd/serverid.c and added checking for valid Server ID's in
865 silc_server_new_server. The Server ID must always be based
866 on the server's public IP address.
868 * Added logging of DISCONNECT packet message in the server.
869 Affected file silcd/server.c.
871 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Changed all library interfaces that use Global RNG to also
874 accept SilcRng as argument. Affected files are
875 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
876 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
877 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
878 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
881 * Added function silc_pkcs_generate_key to the
882 lib/silccrypt/silcpkcs.[ch] for applications so that they
883 don't need to do pkcs->pkcs->init calls anymore.
885 * Remove SilcSocketConnection from the SFTP API since it really
886 wasn't needed there. The application has the information
887 saved in its contexts anyway and the SFTP layer doesn't need
888 know about it. Affected files lib/silcsft/silcsftp.h and
889 lib/silcsftp/sftp_[server/client].c.
891 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
892 The SilcSimContext is not SilcSim.
894 * Fixed possible buffer overflows in silc_id_render in the
895 lib/silcutil/silcutil.c.
897 * On EPOC the global crypto module lists are not used at all
898 in the crypto library. Added support for using the constant
899 algorithm list on EPOC. Affected files are
900 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
903 * Fixed the handling of third parameter of KICKED notify, since
904 it was mistakenly updated to SILC Protocol 1.0 even though it
905 is to be included in 1.1. Since it is not in 1.0 it is not
906 mandatory, and this fix now handles it only if it is provided,
907 and it is not error if it is not provided. Affected file
908 lib/silcclient/client_notify.c.
910 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
912 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
913 client. Affected file irssi/src/silc/core/client_ops.c.
915 * Merged with Irssi 0.8.4 from irssi.org CVS.
917 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
919 * Check for valid socket connection in client entries before
920 sending any messages. Fixes a crash, but doesn't fix some
921 other underlaying bug that is lurking there. Affected
922 file silcd/packet_send.c.
924 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
926 * $usermode, $cumode and $cumode_space expandos shouldn't do
927 anything with non-SILC server records. Affected file
928 irssi/src/silc/core/silc-expandos.c
930 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
932 * Fixed the silc_net_check_[host/local]_by_sock to support
933 IPv6 bound sockets as well. Now they can return IPv6 addresses
934 as well. Affected file lib/silcutil/silcnet.c.
936 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
937 Affected lib/silcutil/unix/silcunixnet.c.
939 * Fixed ID rendering (at least on some platforms, not NetBSD)
940 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
942 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
944 * Added silc_hash_public_key and silc_hash_public_key_compare
945 functions to be used with SilcHashTable. They can be used to
946 hash public keys and compare public keys in hash table. Affected
947 file lib/silcutil/silcutil.[ch].
949 * Added support for specifying multiple public keys for Client
950 connection section in server configuration file. This makes it
951 possible to accept multiple public keys from same host, or to
952 make a section that accepts any incoming host, and have the
953 accepted public keys listed in the section.
955 Added functions silc_sever_[find/get]_public_key, added the
956 support for this actually to all connection sections but only
957 the Client section is currently allowed to specify multiple
960 Affected files are silcd/server.c, server_internal.h,
961 command.c, protocol.c, server_util.[ch], packet_receive.c.
963 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
965 * Merged Irssi 0.8.2 from irssi.org CVS.
967 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
969 * If silc_debug is TRUE, also output standard logging messages
970 to stderr with the debug output.
972 Made silc_log_reset_all() flushing all channels before returning.
973 Also fixed some documentation typos.
975 Affected files are lib/silcutil/silclog.[ch].
977 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * Fixed the server to check correctly the amount of connections
980 from single host, by checking also the type of the connection.
981 Fixed also the comparison of number of connections and number
982 of allowed connections. Affected files are silcd/server.c,
985 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Fixed the USERS command reply to save the user's mode on the
988 channel as well. Fixed JOIN command reply to check whether a
989 client is on channel already and not join it twice. Affected
990 file lib/silcclient/command_reply.c.
992 * Added new file silc-expandos.c into irssi/silc/core/ to return
993 various stuff for various signal for the statusbar etc. updating.
994 Now Irssi SILC client prints channel user modes etc. on the
997 * The user mode (like server/router operator changes) is now shown
998 on the Irssi SILC client's statusbar. The affected files are
999 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1001 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1003 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1004 to SILC_SCHEDULE_[UN]LOCK macros.
1006 * Added more error printing to logs in server code. Affected
1007 files silcd/server.c and silcd/protocol.c.
1009 * Fixed -S option parsing in Irssi SILC Client. Affected file
1010 irssi/src/silc/core/silc-core.c.
1012 * Added silc_buffer_alloc_size function. Affected file is
1013 lib/silcutil/silcbuffer.h.
1015 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1017 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1018 constants. Affected files in
1019 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1022 * Changed the internal SFTP Memory FS table to const. Affected
1023 file lib/silcsftp/sftp_fs_memory.c.
1025 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1027 * Fixed the buffer formatting and unformatting routines to
1028 check the size of 64 bits types with sizeof(). Affected

1045 silc_net_gethostbyname[_async]. If it is TRUE it will return
1046 IPv6 address over IPv4. If FALSE IPv4 address is returned
1047 even if IPv6 address was found. Affected files
1048 lib/silcutil/silcnet.[ch].
1050 * Added support silc_net_create_connection[_async] to fallback
1051 to IPv4 address if IPv6 address could not be used (like if
1052 it doesn't work on a specific system). Affected file in
1053 lib/silcutil/unix/silcunixnet.c.
1055 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1064 application does not need to define them. Affected file
1065 includes/silcincludes.h.
1067 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1068 old name went against naming convention. Applications now
1069 include "silcclient.h" instead of "clientlibincludes.h".
1070 Removed includes/clientlibincludes.h, it is redundant now.
1072 * Renamed includes/version.h to silcversion.h.
1074 * Added really preliminary support for OS/2 into the util
1075 library. Only thread & mutex API is implemented, others
1076 are still to be implemented. Created the lib/silcutil/os2/
1077 directory. Created also file includes/silcos2.h.
1079 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1110 * Added `user_count' to the SilcChannelEntry which now tells the
1111 number of users on the channel. The user count is now saved
1112 in normal server of global channels as well. Affected files
1113 silcd/server.c, idlist.h, packet_receive.c and command.c.
1115 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1116 include file utility functions.
1118 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1119 instead of calling directly OS routines.
1121 * Fixed NICK change printing in Irssi SILC Client. Fixed
1122 KICKED notify printing in Irssi SILC Client. Affected file
1123 irssi/src/silc/core/client_ops.c.

1131 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1132 the SKE interface a bit.
1134 * Fixed padding problem in PKCS#1. The padding was not actually
1135 random since the random number generator was used incorrectly.
1136 This security bug affects only when encrypting with PKCS#1, and
1137 it is not currently used at all in SILC. SILC only use signing
1138 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1140 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1198 is now done in silc_core_init() which also fixes autoconnecting
1201 Affected files irssi/src/silc/core/silc-core.c,
1202 irssi/src/fe-text/silc.c.
1204 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1206 * Added new configuration options and blocks:
1207 keepalive_secs, reconnect_count, reconnect_interval,
1208 reconnect_interval_max, reconnect_keep_trying and
1209 require_reverser_lookup. Added ConnectionParam block, and
1210 implemented the connection parameters when connecting as
1211 initiator and when accepting connections as responder.

1223 the connection configuration object from the SilcServerConnection
1224 object instead of finding it during the connecting phase.
1225 Added the configuration object to SilcServerConnection struct.
1226 Affected files silcd/server_internal.h, server.c.
1228 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1230 * Add the client on channel after it was resolved at the
1231 channel message receiving, and it was not already on the
1232 channel. Affected file lib/silcclient/client_channel.c.
1234 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1250 authentication to be set at the same time.
1252 Added `prefer_passphrase_auth' setting in config file which
1253 can be used to set to prefer passwd auth if both passwd and
1254 public key is set. If not set, public key is preferred.
1255 This has effect only when being initiator (responder will try
1258 Added support for authentication with passphrase and public key
1259 at the same time. The passphrase is tried first always since
1260 it is faster to check.
1262 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1264 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1310 * Fixed the file transfer's key agreement payload to include
1311 zero port also if the hostname is NULL because it could not
1314 Call file transfer monitor callback now also if error occurs
1315 during key agreement protocol.
1317 Changed the silc_client_file_send interface to return the
1318 SilcClientFileError instead of session id. The session ID
1319 is returned into pointer provided as argument.
1321 Check that the file exists locally before sending the
1322 file transfer request at all.
1324 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1326 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1338 * Fixed the channel message payload decryption in the function
1339 silc_channel_message_payload_decrypt to not modify the original
1340 buffer before it is verified that the message decrypted
1341 correctly. Otherwise, next time it is called with correct
1342 channel key it won't encrypt since the payload is corrupted.
1343 Affected file lib/silccore/silcchannel.c.
1345 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1358 the table with foreach callback. The current entry may
1359 become invalid in the callback but it was referenced after
1360 the callback returned.
1362 Do not allow auto rehashing of hash table during the
1363 silc_hash_table_foreach operation, for same reasons as it is
1364 not allowed for SilcHashTableList. Affected files are
1365 lib/silcutil/silchashtable.[ch].
1367 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1377 lib/silcclient/client_prvmsg.c.
1379 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1381 * Added function silc_client_add_channel,
1382 silc_client_replace_channel_id, and removed functions
1383 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1384 from client library.
1386 * Added cross reference of the joined channels to the

1388 users list to SilcHashTable. The affected files are
1389 lib/silcclient/idlist.[ch].
1391 * Fixed a bug in hash table tarversing. While the hash table
1392 is traversed with SilcHashTableList the table must not be
1393 rehashed. It is now guaranteed that auto rehashable tables
1394 are not rehashed while tarversing the list. Also defined that
1395 silc_hash_table_rehash must not be called while tarversing
1396 the table. Added function silc_hash_table_list_reset that must
1397 be called after the tarversing is over. The affected files are
1398 lib/silcutil/silchashtable.[ch].
1400 * Changed all hash table traversing to call the new
1401 silc_hash_table_list_reset in server and in client library.
1403 * Added function silc_client_on_channel to return the
1404 SilcChannelUser entry if the specified client entry is joined
1405 on the specified channel. This is exported to application as
1406 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1408 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1411 server. The notify for mode change must be sent always and
1412 not only if !cmd->pending. Affected file silcd/command.c.
1414 * Fixed the WHOWAS command's reply sending to support the
1415 lists correctly. Affected file silcd/command.c.
1417 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1419 * When sending JOIN command to router for processing the
1420 sender's old command identifier was not saved back to the
1421 sender's command context, fixed now. The affected file is
1424 * Create the key in JOIN command of the router did not return
1425 the channel key, added check for this. Affected file is
1428 * Fixed a channel ID update bug in JOIN command reply. Do
1429 not directly upgrade the ID but call the function
1430 silc_idlist_replace_channel_id if the ID was changed.
1431 Affected file silcd/command_reply.c.
1433 * Fixed memory leaks from command calling if it would fail.
1434 Affected file silcd/command.c.

1461 functions. Affected file silcd/server.c.
1463 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1464 which ID was changed. This way the router will send the
1465 user list for the channel again, and server won't be in
1466 desync in some rare circumstances. Affected file is
1467 silcd/packet_receive.c.
1469 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1516 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1518 * Fixed the NICK command to always give the unformatted
1519 nickname to the one giving the NICK command. If unformatted
1520 nickname is cached already it will be formatted and the
1521 local entry will always get the unformatted nickname.
1522 Affected file lib/silcclient/idlist.c.
1524 * Fixed some double frees from client library commands.
1525 Affected file is lib/silcclient/command.c.
1527 * Fixed CUMODE command in server to assure that no one can
1528 change founder's mode than the founder itself, there was a
1529 little bug. Affected file silcd/command.c.
1531 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1533 * Removed the SilcClientCommandDestructor from the client
1534 libary, it is not needed anymore. Affected files are
1535 lib/silcclient/silcapi.h, command[_reply].[ch],
1536 client_notify, idlist.c.
1538 * Fixed GETKEY command to first resolve client, and then

1541 lib/silcclient/command.c.
1543 * Added silc_client_start_key_exchange_cb and lookup the
1544 remote hostname and IP address before starting the key
1545 exchange with server. The affected file is
1546 lib/silcclient/client.c.
1548 * The server's public key is now saved using the IP address
1549 of the server and not the servername for the filename.
1550 The hostname public key filename is checked as an fall back
1551 method if the IP address based filename is not found.
1553 Fixed the GETKEY command to save the fetched server key
1554 in correct filename.
1556 Print the remote server's hostname now when new key is
1557 received during connection process. Affected file is
1558 irssi/src/silc/core/client_ops.c.
1560 * Return always our own public key to the client if it asks
1561 for it with GETKEY command. Affected file silcd/command.c.
1563 * Removed the use_auto_addr variable from default config
1564 file since it was in wrong section. Affected file is
1567 * Fixed TOPIC_CHANGE notification to not route it when it
1568 was sent using silc_server_send_notify_to_channel function.
1569 Affected file silcd/command.c.
1571 * Fixed silc_server_send_notify_kicked to send the kicker's
1572 Client ID also, it was missing. Affected files are
1573 silcd/command.c, silcd/packet_send.[ch].
1575 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1577 * Do not save client history information in SERVER_SIGNOFF.
1578 Fixes the bug in normal server that it does not detect
1579 the client becoming valid after the server becomes back
1580 online. Affected file silcd/server_util.c.
1582 * Added `sock_error' field into the SilcSocketConnection
1583 context. When error occurs during socket operation (read
1584 or write) the error is saved. Added also new function
1585 silc_socket_get_error to return human readable socket error
1586 message. Affected files are lib/silcutil/silcsockconn.[ch],
1587 lib/silcutil/unix/silcunixsockconn.c, and
1588 lib/silcutil/win32/silcwin32sockconn.c.
1590 * The server now prints the socket error message in the
1591 signoff for client. Affected file silcd/server.c.
1593 * Fixed the `created' channel information sending from router
1594 to server in JOIN command. Checks now whether the channel
1595 really was created or not and set it according that.
1597 Fixed the JOIN command to use the client entry's current
1598 ID during the joining procedure instead of the one it sent
1599 in the command (it is checked though), since it can change
1600 between the packet processing and command processing, and
1601 would just case unnecessary pain in the client end. Affected
1602 file silcd/command.c.
1604 * Fixed a channel key payload sending to use correct channel
1605 ID when the server was forced to change the channel's ID by
1606 router. Router sent the key payload with the old Channel ID.
1607 Affected file silcd/packet_receive.c.
1609 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Call silc_server_save_channel_key only if the key payload
1612 was provided in the JOIN command's command reply. Affected
1613 file silcd/command_reply.c.
1615 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1617 * Fixed silc_mp_sizeinbase to return the value correctly with
1618 MPI. Affected file lib/silcmath/mp_mpi.c.
1620 * Fixed the stop_server signal to correctly stop the scheduler
1621 and gracefully stop the server when SIGTERM or SIGINT signals
1622 are received. Affected file silcd/silcd.c.
1624 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1626 * Simple handling of TERM and HUP signals. Also added some log
1627 flushing call around. Affected file is
1630 * Fixed small bugs in silclog.c. Now buffering output will take
1631 effect after 10 seconds since startup: This will ensure that
1632 no important startup messages are lost. Also output redirection
1633 will preserve original format ([Date] [Type] message).
1634 Affected file is lib/silcutil/silclog.c.
1636 * Added two options to the config file, in the logging section:
1637 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1638 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1640 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1642 * Do not print the warning about log files not being initialized
1643 more than once to avoid excess logging. Affected file is
1644 lib/silcutil/silclog.c.
1646 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1647 the SIM copying in make install in Makefile.am.pre.
1649 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1651 * Rewritten silclog APIs. Globally interesting changes follows:
1652 silc_log_set_files() changed to silc_log_set_file().
1653 silc_log_set_callbacks() changed to silc_log_set_callback().
1654 ROBOdoc documented silclog header file.
1655 SilcLogCb now returns bool to wether inihibit the default
1656 handler or not (to keep the old behaviour return always TRUE).
1657 The new APIs should also fix the problem of the
1658 silcd_error.log file that was written in the current directory.
1661 Log files streams will remain opened after silc_log_set_file()
1662 call, means less CPU usage notably on high traffic servers.
1663 File streams are now full buffered, and flushed to the disk
1664 every 5 minutes, lesses HD activity and CPU usage.
1665 Messages can be redirected, allowing admins to configure
1666 one single logfile for all server messages.
1667 the silc_log_quick global variable to activate fast-logging.
1668 Affected files lib/silcutil/silclog.[ch]
1670 * Changed some code to conform new silclog APIs. Affected
1671 files are doc/example_silcd.conf.in, silcd/server.c
1672 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1675 * Fixed a memory leak that could occur in some situations.
1676 Affected file silcd/serverconfig.c.
1678 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1680 * Added the silc_client_del_client to remove the client from
1681 all channels as well. Affected file lib/silcclient/idlist.c.
1683 * Fixed the client library to correctly remove the client
1684 from all channels when the client entry is being destroyed.
1685 Affected file lib/silcclient/client_notify.c, command.c.
1687 * Added auto-nicking support to the client library. If the
1688 applicatio now sets client->nickname it will be sent to the
1689 server after connecting by the library. This way for example
1690 SILCNICK (or IRCNICK) environment variables will have effect
1691 and always change the nickname automatically to whatever
1692 it is wanted. Affected file lib/silcclient/client.[ch].
1694 * Renamed silc_server_command_bad_chars to the
1695 silc_server_name_bad_chars and moved it to the
1696 silcd/server_util.[ch]. Added also new function
1697 silc_server_name_modify_bad to return nickname that
1698 includes bad characters as new nickname without those
1699 bad characters. This check and modify is now used in
1700 silc_server_new_client when the username is initially set
1701 as nickname, so it must be checked to be valid nickname.
1702 Affected file silcd/packet_receive.c.
1704 * The nickname length is now taken from the packet for real
1705 and not trusted to strlen() since it clearly can return
1706 wrong length for nickname including bad characters. This
1707 also applies to channel names. Affected file silcd/command.c.
1709 * Removed the lib/silcsilm/modules directory. Modules are now
1710 compiled into the lib/silcsim. Fixed the copying of the
1711 modules to follow symbolic links in Makefile.am.pre.
1713 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1715 * Fixed silc_string_regexify list creation. Fixes bugs with
1716 BAN and INVITE commands in server. The affected file is
1717 lib/silcutil/unix/silcunixutil.c.
1719 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1721 * Removed the command destructor entirely from the server's
1722 command and command reply routines. It is not needed, and
1723 its usage was buggy and caused crashes. Affected files are
1724 silcd/command[_reply].[ch].
1726 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1728 * Cancel protocol and NULL sock->protocol if timeout
1729 occurred during protocol. Affected file silcd/server.c.
1731 * Cancel protocol timeouts always before calling the final
1732 callback, to assure that after final callback is called
1733 no other state will be called for the protocol anymore.
1734 Affected file silcd/protocol.c.
1736 * Print error log if incoming connection configuration could
1737 not be found. Affected file silcd/server.c.
1739 * Fixed JOIN command to correctly save the founder mode
1740 to the client on normal SILC server, when the channel
1741 was created by the router. Affected file silcd/command.c.
1743 * Fixed LIST command (hopefully) to send correct reply
1744 packets. Affected file silcd/command.c.
1746 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * The silc_packet_receive_process now returns FALSE if the
1749 read data was invalid packet, and TRUE if it was ok.
1751 The server now checks that if unauthenticated connection
1752 sends data and its processing fails the server will close
1753 the connection since it could be a malicious flooder.
1755 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1757 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1759 * Make sure the warning about error opening a log file is
1760 printed only once and not everytime it fails (produces
1761 too much useless log). Affected file lib/silcutil/silclog.c.
1763 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1765 * Made the silc_server_daemonise() function more readable.
1766 Affected file silcd/server.c.
1768 * Pid file is now optional, the user may comment it out from
1769 the config file. Removed define SILC_SERVER_PID_FILE, we
1770 don't need a default any longer. Affected file
1771 configure.in.pre, lib/Makefile.am.pre.
1773 * Make some use of the pid file. The server now dies at startup
1774 if it detects a valid pid file on his path. The server would
1775 die anyway in this circumstance, because of the bind() failure.
1776 Affected file silcd/silcd.c.
1778 * No longer compiling lib/dotconf.
1780 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Fixed JOIN command parsing not to crash. Affected file
1783 lib/silcclient/command.c.
1785 * Fied the NICK_CHANGE notify to add the new client entry
1786 even it is resolved. This removes an <[unknown]> nick
1787 thingy bug in the client. Affected file is
1788 lib/silcclient/client_notify.c.
1790 * Do not try to allocate 0 bytes (efence does not like it)
1791 in lib/silccore/silccomand.c when encoding payload.
1793 * Do not take IRCNICK as nickname in Irssi SILC client since
1794 it is not possible to set nickname before hand connecting
1795 the server (TODO has an entry about adding auto-nicking
1798 * Changed the silc_server_command_pending to check whether
1799 there already exists an pending entry with the specified
1800 command, command identifier and pending callback. This is
1801 to fix IDENTIFY and WHOIS related crashes that may register
1802 multiple pending commands with same identifier. Affected
1803 file silcd/command.c.
1805 * Fixed the server to reconnect to the router even if it
1806 was already reconnecting and EOF was received. This to
1807 fix a possibility that the server wouldn't ever try to
1808 auto-reconnect to the router. Affected file silcd/server.c.
1810 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1812 * Fixed the server's password authentication to use the
1813 length of the locally saved password, and not the one
1814 sent in the packet. Affected file silcd/protocol.c.
1816 * Fixed same password authentication problem in the
1817 Authentication Payload handling routines in
1818 lib/silccore/silcauth.c.
1820 * Yet another password authentication problem fixed with
1821 channel password handling in silcd/command.c.
1823 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * If first character of string in silc_parse_userfqdn is '@'
1826 then do not parse it. Affected file is
1827 lib/silcutil/silcutil.c.
1829 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Fixed minor bug in IDENTIFY command reply sending, which
1832 caused various weird problems during JOIN when it was
1833 resolving names for users. Affected file silcd/command.c.
1835 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1837 * Fixed the IDENTIFY command reply sending to chech better valid
1838 clients. It was possible to send incomplete list of replies.
1839 Affected file silcd/command.c.
1841 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Added silc_client_command[s]_[un]register functions now to
1844 dynamically register the commands in client library. Removed
1845 the static table of commands. This allows the client library
1846 to call commands without causing the application to know about
1847 what commands library has called.
1849 Removed the INFO command reply kludge to detect when the command
1850 was called by library. Now library use its own command reply
1851 function for INFO command.
1853 Added function silc_client_command_call to call a command.
1854 Application can use it to call command, not access the structure
1857 Now all commands that are sent by the client library (not
1858 explicitly sent by application) use own command reply functions.
1860 Affected files around lib/silcclient/ and in
1861 irssi/src/silc/core/.
1863 * Fixed the WHOIS command reply sending to chech better valid
1864 clients. It was possible to send incomplete list of replies.
1866 Fixed the WHOIS and IDENTIFY to send the request to router
1867 if normal server did not do it and did not find any results.
1869 Affected file silcd/command.c.
1871 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1873 * Moved the internal data from SilcClient context into its
1874 own file, not accesible to application. Affected files
1875 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1876 and other files in client library.
1878 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Added doc/examples installation target in Makefile.am.pre.
1883 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1885 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1886 commands the found client entry will be removed from the
1887 cache, after notifying application about the error. Affected
1888 file lib/silcclient/command_reply.c.
1890 * Changed the /MSG to check for exact nickname user gave, and
1891 not let `nick' match `nick@host' if it is only one found. Now,
1892 user must type the exact nickname (like nick@host2) even if
1893 there are no more than one same nicks found. This is to avoid
1894 a possibility of sending nickname to wrong nickname since
1895 `nick' could match `nick@host'. Affected file is
1896 irssi/src/core/silc-servers.c.
1898 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Do not print "you are now server operator" or similar when
1901 giving /away command. Affected files are
1902 irssi/src/silc/core/client_ops.c, silc-servers.h.
1904 * Made the silc_server_command_pending_error_check to send
1905 the same command reply payload it received back to the
1906 original sender of the command. This way all arguments
1907 that was received by the server will be received by the
1908 client too. Affected file silcd/command.c.
1910 * Added the silc_idcache_add to return the created cache entry
1911 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1913 * Add global clients to expire if they are not on any channel.
1914 This is because normal server will never know if they signoff
1915 if they are not on any channel. The cache expiry will take
1916 case of these entries. This is done by normal servers only.
1917 The affected files are silcd/command_reply.c,
1918 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1920 * If server receives invalid ID notification for WHOIS or
1921 IDENTIFY and the ID exists in the lists, it is removed.
1922 Affected file silcd/command_reply.c.
1924 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1925 in client then client entry that it matches is searched and
1926 the nickname is printed on the screen for user. Affected
1927 file irssi/src/silc/core/client_ops.c.
1929 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * Use cache entry expire time in the LIST command reply to
1932 purge old entries from the cache after the LIST command
1933 reply has been received. This way we don't have non-existent
1934 entries in the cache for too long. Affected file is
1935 silcd/command_reply.c.
1937 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * If we are normal server, and we've not resolved client info
1940 in WHOIS or IDENTIFY from router, and it is global client,
1941 we'll check whether it is on some channel. If it is not
1942 then we cannot be sure about its validity and will resolve it
1943 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1944 file silcd/command.c.
1946 * Search channel by name (if possible) rather than by ID
1947 in IDENTIFY command's command reply. Affected file is
1948 silcd/command_reply.c.
1950 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1952 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1953 Updated specs and implemented it. Affected file silcd/command.c,
1954 silcd/packet_send.c and silcd/packet_receive.c.
1956 * Implemented the <founder auth> payload handling in the JOIN
1957 command. If provided all conditions for channel joining
1958 except requirement to provide correct passphrase can be
1959 overrided by the channel founder. Updated the protocol specs.
1960 Affected file silcd/command.c.
1962 Added support for founder auth in JOIN command in client
1963 library. Fixed the parsing of the JOIN command now to support
1964 all options as they should be. The affected file is
1965 lib/silcclient/command.c.
1967 * Optimized the WHOIS and IDENTIFY commands to send the request
1968 to router only if it includes nicknames or other names. If
1969 they include only IDs then check the local cache first before
1970 routing. Affected file is silcd/command.c.
1972 * Added channels topic announcements. Affected file is
1973 silcd/packet_receive.c and silcd/server.c.
1975 * Fixed the silc_server_send_notify_topic_set to really destine
1976 the packet to channel. Affected file silcd/packet_send.c.
1978 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1979 library. Affected file lib/silcclient/client_notify.c.
1981 * Added UMODE announcements. Affected file silcd/server.c.
1983 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Memory leak fixes in:
1987 lib/silcutil/silcsockconn.c
1988 lib/silcske/silcske.c
1989 lib/silcske/groups.c
1991 lib/silccrypt/silcpkcs.c
1992 lib/silccore/silccommand.c
1993 lib/silccore/silcidcache.c
1998 * ROBOdoc documented the lib/silcske/groups.h file and a
1999 bit changed the interface for better.
2001 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2003 * Update the client entry context in the ID cache after
2004 nick change. Affected file lib/silcclient/command.c.
2005 Fixes the CUMODE command when regaining founder privileges,
2006 and a little WHOIS problem.
2008 * Fixed silc_net_gethostbyname to correctly call the
2009 inet_ntop. Affected file lib/silcutil/silcnet.c.
2011 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2013 * Added IPv6 support checking to the configure.in.pre, added
2014 also --enable-ipv6 option to override the check. Affected
2015 file configure.in.pre.
2017 * The silc_thread_create now calls the start function
2018 directly if threads support is not compiled in. Removes
2019 ugly #ifdef's from generic code. Affected files are
2020 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2022 * Added silc_net_gethostby[name/addr]_async to asynchronously
2023 resolve. Affected files are lib/silcutil/silcnet.[ch].
2025 * Added support for rendering IPv6 based server, client and
2026 channel IDs. Affected file lib/silcutil/silcutil.c.
2028 * Added support for creating IPv6 based server IDs. Affected
2029 file is silcd/serverid.c.
2031 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2033 * Added silc_net_gethostby[addr/name] into the
2034 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2035 routines. Added silc_net_is_ip[4/6]. Affected file is
2036 lib/silcutil/unix/silcunixnet.c. All routines that take
2037 address as argument now supports both IPv4 and IPv6 addresses.
2039 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2041 * Fixed LIST command reply sending in server. Affected file
2044 * Server now sends the kicker's client ID in the KICK notify
2045 to the kicked client. Affected file silcd/command.c.
2047 * The client library now parses the kickers client ID and
2048 UI displays it. Affected files lib/silcclient/client_notify.c
2049 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2051 * Made all payload parsing function prototypes consistent.
2052 They all take now const unsigned char * and uint32 pair as
2053 the payload data instead of SilcBuffer. Changes all around
2054 the source tree. Other unsigned char* -> const unsigned char*
2055 changes around the tree as well.
2057 * Optimized SFTP client and server packet sending not to
2058 allocate new buffer for each packet but to recycle the
2059 first allocated buffer. Affected files are
2060 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2062 * Optimized the SFTP client to use SilcList instead of
2063 SilcDList for requests, because it is faster. Affected file
2064 is lib/silcsftp/sftp_client.c.
2066 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2067 into lib/silccore/silcid.[ch].
2069 Renamed silcpayload.[ch] into silcargument.[ch].
2071 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2073 * If client entry is deleted with active key agreement
2074 session, abort the session.
2076 The silc_client_abort_key_agreement now calls the completion
2077 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2079 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2082 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2084 * Don't use __restrict in older GCC's. Affected file is
2085 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2087 * silc_net_localhost now attempts to reverse lookup the
2088 IP/hostname. Affected file lib/silcutil/silcnet.c.
2090 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2091 command. It can be used to gain founder privileges at
2092 the same time when joining the channel.
2094 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2095 kicker's client ID as well. Updated protocol specs.
2097 Defined that the server must send SILC_COMMAND_IDENTIFY
2098 command reply with error status to client who sent
2099 private message with invalid client ID.
2101 Updated the protocol specification.
2103 * Added silc_server_send_command_reply to send any
2104 command reply. Affected file silcd/packet_send.[ch].
2106 * Added silc_id_payload_encode_data to encode ID payload
2107 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2109 * The server now send IDENTIFY command reply with error
2110 status if client ID in private message is invalid. Affected
2111 file silcd/packet_receive.c.
2113 * Save the server key file with server's IP address in
2114 the filename instead of hostname. The affected file is
2115 irssi/src/silc/core/client_ops.c.
2117 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2119 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2122 * Added libtool support for compiling shared objects in
2123 lib/silcsim. Affected file configure.in.pre and
2124 lib/silcsim/Makefile.am. Original patch by cras.
2126 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Pid file configuration, and server's config file fixes
2129 patch by toma. Updated CREDITS file.
2131 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Fixed silc_client_channel_message to not try to decrypt
2134 the message twice if it resolved the destination client
2135 information. This could cause of dropping one channel
2136 message. Affected file lib/silcclient/client_channel.c.
2138 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2141 lib/silcclient/client.c. This function is used when the SILC
2142 Client is run under some other scheduler, or event loop or
2143 main loop. On GUI applications, for example this may be
2144 desired to used to run the client under the GUI application's
2145 main loop. Typically the GUI application would register an
2146 idle task that calls this function multiple times in a second
2147 to quickly process the SILC specific data.
2149 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2151 * Fixed silc_server_drop() for dropping the supplementary
2152 groups as well, this could cause a security hole on some
2155 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2160 * Write PID file after dropping privileges. Added -F option
2161 to run server on foreground. A patch by debolaz.
2162 Affected files silcd/server.c, silcd/silcd.c.
2164 * Fixed MOTD to return the MOTD file server name. Affected
2165 file silcd/command.c.
2167 * Added INFO command reply handling to the Irssi SILC Client.
2168 Affected file irssi/src/silc/core/client_ops.c.
2170 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2172 * Fixed the silc_idcache_list_* routines to really support
2173 the dynamic list. Fixes a crash. Affected file is
2174 lib/silccore/silcidcache.c.
2176 * Fixed the LIST command reply to really call LIST command's
2177 pending callbacks. Affected file silcd/command_reply.c.
2179 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Update conn->local_entry->nickname after giving NICK
2182 command. Affected file lib/silcclient/command.c.
2184 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2186 * Added the [pid] option to the silcd configuration file
2188 Affected files: serverconfig.[ch] and silcd.c
2190 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Save fingerprint in WHOIS command reply in server.
2193 Affected file silcd/command_reply.c.
2195 * Fixed NICK commands pending callback registration.
2196 Affected file lib/silcclient/command.c.
2198 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Use ++server->cmd_ident when sending commands in server,
2201 instead of random number. Affected file silcd/command.c.
2203 * Fixed GETKEY command reply to call actually GETKEY pending
2204 command callbacks. Affected file silcd/command_reply.c.
2206 * A bit stricter check for nicknames. Check for same nickname
2207 in NICK command also. Affected file silcd/command.c.
2209 * Do not call INFO command everytime client ID changes, only
2210 during first connecting. Affected file lib/silcclient/client.c.
2212 * Set the new nickname only after successful command reply for
2213 NICK command is returned by server. Affected file
2214 lib/silcclient/command.c.
2216 * Remove nicknames from nicklist during server_signoff notify.
2217 Should fix /NAMES bit more. The affected file is
2218 irssi/src/silc/core/silc-channels.c.
2220 * Added `fingerprint' field to the SilcIDListData in the
2221 silcd/idlist.h to hold the fingerprint of the client's
2224 Send the fingerprint of the client's public key in WHOIS
2227 Affected files silcd/command.c, and silcd/idlist.[ch].
2229 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2230 create fingerprint from given data.
2232 * Show the fingerprint of the client's public key in WHOIS.
2233 Affected files irssi/src/module-formats.[ch] and
2234 irssi/src/silc/core/client_ops.c.
2236 * Format the multiple same nicknames also during JOIN and
2237 NICK_CHANGE notifys. Affected file is
2238 lib/silcclient/client_notify.c.
2240 * Do not print error on screen for invalid private message
2241 payload since it can come if someone is sending private
2242 messages with wrong key. Affected file
2243 lib/silccore/silcprivate.c.
2245 * Fixed multiple concurrent /PING crash. Affected file
2246 lib/silcclient/command.c.
2248 * Changed the wrong ID encoding. All IP addresses must be
2249 in MSB first order in encoded format. They were encoded
2250 wrong and was in LSB format. Affected files are
2251 silcd/serverid.c, lib/silcutil/silcutil.c.
2253 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2255 * Call the `connect' client operation through the scheduler
2256 in case of error. Affected file lib/silcclient/client.c.
2258 * Call the `failure' client operation even if the error
2259 occurred locally during a protocol. Affected file is
2260 lib/silcclient/protocol.c.
2262 * Added support of sending LIST command to router from normal
2263 server. This way normal server can get list of all channels
2264 in the network too. Fixed the channel list sending in the
2265 server too. Affected files are silcd/command.c, and
2266 silcd/command_reply.[ch].
2268 * Added silc_server_update_channels_by_server and
2269 silc_server_remove_channels_by_server. They are used during
2270 disconnection of primary router and in backup router protocol.
2271 Affected file silcd/server_util.[ch], silcd/server.c and
2272 silcd/server_backup.c.
2274 * Fixed channel adding to global list in IDENTIFY command
2275 reply in server. Affected file silcd/command_reply.c.
2277 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2279 * If the incoming packet type is REKEY or REKEY_DONE process
2280 that packet always synchronously. Fixes yet another MAC
2281 failed error on slow (dialup) connections. Affected file
2282 lib/silcclient/client.c and silcd/server.c.
2284 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Call check_version SKE callback for initiator too. Affected
2287 file lib/silcske/silcske.c.
2289 * Implemented fix for security hole found in the SKE that was
2290 fixed in the specification few days back; the initiator's
2291 public key is now added to the HASH value computation.
2292 Added backwards support for the old way of doing it too, for
2293 old clients and old servers. Affected file is
2294 lib/silcske/silcske.c.
2296 * Enabled mutual authentication by default in SKE. If initiator
2297 is not providing mutual authentication the responder will
2298 force it. This will provide the proof of posession of the
2299 private key for responder. The affected files are
2300 lib/silcclient/protocol.c and silcd/protocol.c.
2302 * Do not cache anymore the server's public key during SKE.
2303 We do mutual authentication so the proof of posession of
2304 private key is done, and if the server is authenticated in
2305 conn auth protocol with public key we must have the public
2306 key already. Affected file silcd/protocol.c.
2308 * Added new global debug variable: silc_debug_hexdump. If
2309 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2310 file lib/silcutil/silclog.[ch].
2312 * Fixed compilation warning due to char * -> const char *.
2313 Affected files lib/silcutil/silcnet.h, and
2314 lib/silccore/silcauth.[ch].
2316 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Fixed CMODE command when new channel key was created. If
2319 the creation failed the old key was removed. Next time giving
2320 same command would crash the server since the old key was
2321 freed already. Affected file silcd/command.c.
2323 * Fixed the silc_server_announce_get_channels to not crash
2324 on reconnect. Affected file silcd/server.c.
2326 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Added silc_log_set_debug_string function to set a regex
2329 string to match for debug output. Only the function names,
2330 or filenames matching the given debug string is actually
2331 printed. This way it is possible to filter out those debug
2332 strings that user is not interested in.
2334 Fixed a bug in silc_string_regexify.
2336 Affected files lib/silcutil/silclog.[ch], and
2337 lib/silcutil/unix/silcunixutil.c.
2339 * Changed the -d options in both server and Irssi SILC client
2340 to take the debug string as argument. Affected files
2341 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2343 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Added silc_hash_babbleprint to create a Bubble Babble
2346 Encoded fingerprint. The encoding is developed by Antti
2347 Huima (draft-huima-babble-01.txt), and it creates human
2348 readable strings out of binary data. Affected file
2349 lib/silccrypt/silchash.[ch].
2351 * Print the babble print now in addition of fingerprint as well
2352 in Irssi SILC client. Affected files are
2353 irssi/src/fe-common/silc/module-formats.[ch],
2354 irssi/src/fe-common/silc/core/client_ops.c.
2356 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Fixed a security problem found in SKE. The initiator's
2359 public key too is now added to the HASH hash value creation
2360 which is signed by the responder to create the SIGN value.
2361 This will prevent anyone in the middle to lie to the responder
2362 about the initiator's public key. If this is done now, the
2363 man in the middle will get caught. Updated the protocol
2366 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2368 * Better installation directory handling. Configure module
2369 paths and other paths automatically to example_silc* files
2370 in doc/. A patch by toma.
2372 * Fixed compiler warning from MPI library, and from SILC RNG.
2375 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2376 It can be configured with ./configure. A patch by toma.
2378 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Find correct make to use in prepare-clean. A patch by
2381 toma. Affected file prepare-clean.
2383 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2385 * Added irssi variables use_auto_addr, auto_bind_ip,
2386 auto_bind_port and auto_public_ip.
2388 * Changed the interface for silc_client_send_key_agreement
2389 in lib/silcclient/silcapi.h
2393 irssi/src/silc/core/silc-core.c
2395 lib/silcclient/silcapi.h
2396 irssi/src/silc/core/silc-channels.c
2397 lib/silcclient/client_keyagr.c
2400 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2402 * Added silc_pkcs_public_key_compare to compare two
2403 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2405 * Check that the client who set the founder mode on the
2406 channel is the same client that is giving the founder
2407 mode to itself. It is done by comparing the saved public
2408 key (it is saved even in the authentication is passphrase).
2409 Affected file silcd/command.c.
2411 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2413 * Do not process packet for disconnected socket connection.
2414 Affected file lib/silccore/silcpacket.c.
2416 * Process the DISCONNECT packet through scheduler in the
2417 client library. Affected file lib/silcclient/client.c.
2419 * Fixed the silc_client_packet_parse to not to increase
2420 the packet sequence number if the conn->sock and the
2421 current socket connection is not same. This can happen
2422 for example during key agreement when the conn includes
2423 multiple socket connections (listeners). Affected file
2424 lib/silcclient/client.c.
2426 * The sender of the file transfer request now provides also
2427 the pointer (listener) for the key exchange protocol. If
2428 the listener cannot be created then it sends empty key
2429 agreement and lets the receiver provide the listener.
2431 Added `local_ip' and `local_port' arguments to the
2432 silc_client_file_send. If they are provided they are used,
2433 if not then it will attempt to find local IP address, if
2434 not found or bind fails then the remote client will provide
2437 Affected files are lib/silcclient/client_ftp.c and
2438 lib/silcclient/silcapi.h.
2440 * Extended the FILE SEND command to support defining the
2441 local IP and port for key exchange listener. They are
2442 optional. Affected file irssi/src/silc/core/silc-servers.c.
2444 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2446 * Defined to WHOIS command reply the sending of fingerprint
2447 of the client's public key (if the proof of posession of the
2448 corresponding private key is verified by the server).
2449 Updated to the protocol specification.
2451 * Added support of receiving the client's public key's
2452 fingerprint in command reply in client library. Affected
2453 file is lib/silcclient/command_reply.c, and
2454 lib/silcclient/idlist.[ch].
2456 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2458 * Do not send over 128 chars long nickname to the server
2459 in NICK command. Affected file lib/silcclient/command.c.
2461 * Do not send over 256 chars long channel names to the server
2462 in JOIN command. Affected file lib/silcclient/command.c.
2464 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Assure that silc_server_close_connection cannot be called
2467 twice for same socket context. Affected file is
2470 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2472 * Send error message to application if opening file for
2473 writing during file transfer fails. Affected file is
2474 lib/silcclient/client_ftp.c.
2476 Remove all file transfer sessions for a client that we're
2477 removing from ID cache.
2479 Affected file is lib/silcclient/client_ftp.c.
2481 * Fixed silc_net_addr2bin to return correct address. Affected
2482 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2484 * Fixed file transfer session removing on signoff notify.
2485 Affected file irssi/src/silc/core/silc-servers.c.
2487 * Added the SilcClientFileError to be returned in the monitor
2488 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2489 Affected file lib/silcclient/silcapi.h.
2491 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Fixed a crash in silc_client_ftp_free_sessions and
2494 silc_client_ftp_session_free_client. Affected file
2495 lib/silcclient/client_ftp.c.
2497 * Added `disabled' field in the SilcChannelEntry in the server
2498 to indicate if the server entry is disabled. Affected file
2499 silcd/idlist.h, silcd/command[_reply].c.
2501 * SILC server adds now /var/run/silcd.pid everytime it is
2502 started. Affected file silcd/silcd.c.
2504 * Added silc_server_packet_send_clients to send a packet to
2505 the provided table of client entries. Affected file
2506 silcd/packet_send.[ch].
2508 * Fixed a crash in client resolving in client_prvmsg.c in
2509 client library. Affected file lib/silcclient/client_prvmsg.c.
2511 * Do not actually remove the client directly from ID cache
2512 during SERVER_SIGNOFF, but invalidate it. This way we
2513 preserve the WHOWAS info for the client. Affected file
2514 silcd/server_util.c.
2516 * Fixed SERVER_SIGNOFF notify handling in the server. The
2517 server is now able to process incoming SERVER_SIGNOFF notify
2518 for a server that it doesn't even know about. It will remove
2519 the clients provided in the notify. Affected file
2520 silcd/packet_receive.c.
2522 * Check for partial packet in data queue after every packet that
2523 was found from the queue. Return and wait for more data if
2524 there is partial data in queue. Affected file is
2525 lib/silccore/silcpacket.c.
2527 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Added SilcClietFileError enum to indicate error in
2530 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2531 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2532 Affected files lib/silcclient/silcapi.h and
2533 lib/silcclient/client_ftp.c.
2535 * Check that newsize in silc_buffer_realloc is larger than
2536 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2538 * Added better monitor of file transfers. It now monitors
2539 key agreement protocol during the file transfer too. Added
2540 error reporting too. Affected files
2541 irssi/src/silc/core/silc-servers.c,
2542 irssi/src/fe-common/silc/module-formats.[ch].
2544 * Wrote a help file for FILE command.
2546 * Added silc_rng_global_get_byte_fast to get not-so-secure
2547 random data as fast as possible. Random data is read from
2548 /dev/urandom if available and from the SILC RNG if not
2549 available. It is used in padding generation. Affected file
2550 lib/silccrypt/silcrng.[ch].
2552 * All packets in client library are now processed synchronously.
2553 Optimized packet processing a lot. Affected file
2554 lib/silcclient/client.c.
2556 * All server connection packets are processing synchronously
2557 now in server, to optimize packet processing. Affected file
2560 * Include files are installed now only in Toolkit distribution
2561 if make install is given. Affected files: all Makefile.am's.
2563 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Assure that silc_client_notify_by_server_resolve does not
2566 resolve the client information multiple times. If it cannot
2567 be found by the first it cannot be found at all. Affected
2568 file lib/silcclient/client_notify.c.
2570 * Fixed WHOWAS command reply calling. Affected file
2571 lib/silcclient/command_reply.c.
2573 * Removed all references to silc_idlist_get_client from the
2574 Irssi SILC client since that call is internal call used by
2575 the library. The Irssi SILC client will use now client
2576 retrieval functions found in silcapi.h.
2578 * Fixed a bug in resolving nickname info before sending
2579 private message. It used freed memory. Affected file
2580 irssi/src/silc/core/silc-servers.c.
2582 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Assure my_channels statistics cannot go negative in server.
2585 Affected files silcd/server.c, silcd/server_util.c.
2587 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2591 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2593 * Win32 Toolkit changes. Affected files
2594 win32/silc.dsw, win32/libsilc/libsilc.def,
2595 win32/libsilcclient/libsilc.def,
2596 lib/silcutil/silcutil.c, and
2597 lib/sftp/sftp_fs_memory.c.
2599 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Added silc_net_localip to return local host's IP address.
2602 Affected file lib/silcutil/silcnet.[ch].
2604 * If key exchange or rekey protocol is active for a connection
2605 parse all packets syncronously since there might be packets
2606 in packet queue that we are not able to process without first
2607 processing packets before them. Affected file silcd/server,
2608 lib/silcclient/client.c.
2610 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2611 whether library should continue processing the packet.
2612 Affected file lib/silccore/silcpacket.h.

2643 lib/silcutil/silcutil.[ch].
2645 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2647 * Resolve the client info when received private message or
2648 channel message for a client which nickname we don't know.
2649 Affected files lib/silcclient/client_prvmsg.c and
2650 lib/silcclient/client_channel.c.
2652 * Do not crash in /KEY if client is not connected. Affected
2653 file irssi/src/silc/core/silc-channels.c.
2655 * Added SilcClientStatus field to the SilcClientEntry in the
2656 lib/silcclient/idlist.h.
2658 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2659 is incomplete and is being resolved, it won't be resolved
2662 Make sure also that USERS command reply does not resolve
2663 twice information. Affected file is
2664 lib/silcclient/command_reply.c.
2666 Make sure that silc_client_get_clients_by_list does not
2667 resolve twice same information.
2669 * Check for valid client->id in the silc_server_free_client_data.
2670 Affected file silcd/server.c.
2672 * Fixed /GETKEY nick@server not to crash if the server entry
2673 is not found. Affected file lib/silcclient/command.c.
2675 * Fixed the silc_server_check_cmode_rights to check the
2676 requested modes correctly. Affected file silcd/command.c.
2678 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2680 * Better checks for non-printable chars in nick added.
2681 Affected file silcd/command.c.
2683 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Call the silc_server_udpate_servers_by_server in the
2686 primary router that comes back online in the backup resuming
2687 protocol. Otherwise it routes packets wrong. Affected file
2688 silcd/server_util.[ch], silcd/server_backup.c.
2690 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2693 lib/silcutil/silcbuffmt.[ch].
2695 * Redefined the SILC packet header to include the padding
2696 length. Affected file lib/silccore/silcpacket.[ch].
2698 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2699 length for maximum padding up to 128 bytes). Affected
2700 file lib/silccore/silcpacket.h.
2702 * Removed all backwards support for old 0.5.x MAC thingies.
2703 The SILC packet header change makes it impossible to be
2704 backwards compatible.
2706 * Send the ENDING packet with timeout in the backup resuming
2707 protocol. This is to assure that all routers has connected
2708 to the primary router. Affected file silcd/server_backup.c.
2710 * Changed the RNG to take the first IV from random data. It
2711 used to take it from zero actually. Changed the RNG also
2712 to use /dev/urandom during session. /dev/random is used
2713 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2715 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Changed the SILC packet header to have the first two bytes
2718 (the packet length) encrypted. Affected files aroung the
2719 code tree, lib/silccore/silcpacket.[ch]. Removed the
2720 SilcPacketCheckDecrypt callback. It is not needed anymore
2721 since the silc_packet_receive_process will determine now
2722 whether the packet is normal or special.
2724 * Implemented the unidirectional MAC keys. Affected files
2725 lib/silcske/silcske.c, silcd/protocol.c and
2726 lib/silcclient/protocol.c.
2728 * Implemented the packet sequence number to the MAC computation.
2729 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2730 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2731 lib/silcclient/protocol.c.
2733 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2735 * Allow backup router to announce servers. All servers
2736 announced by backup router are added to the global list
2737 automatically. Update hte server's socket to our primary
2738 router also when backup router announces a server.
2739 Affected file silcd/packet_receive.c.
2741 * Do not update the client->router in the function
2742 silc_server_udpate_clients_by_server if the client is on
2743 global list. We might fail to find any specific server
2744 for locally connected clients and local cell clients. They
2745 should still use the `from' and not `to' as client->router.
2746 This fixes backup router resuming protocol. Affected file
2747 silcd/server_util.c.
2749 * Decrease channel statistics count only if the channel
2750 deletion worked. Affected files are silcd/server.c and
2751 silcd/server_util.c.
2753 * Added silc_server_update_servers_by_server to update origin
2754 of all server entries. Used during backup router protocol.
2755 Affected files silcd/server_util.[ch], silcd/server.c. and
2756 silcd/backup_router.c.
2758 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2759 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2760 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2761 lib/silccrypt/silchmac.c.
2763 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Assure that router cannot reroute the same channel message
2766 to the sender. Affected file silcd/packet_receive.c.
2768 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Made better checks that the channel message is not sent
2771 to the router it came from. Affected file is
2772 silcd/packet_send.c. Fixed memory leak too.
2774 * Announce informations for incoming router connection, but
2775 only after checking if it is replaced by backup router.
2776 Affected file silcd/packet_receive.c.
2778 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Fixed the backup resuming protocol to work in multiple
2781 router environment. Affected file silcd/server_backup.c.
2783 * Route packet only to one router in the function
2784 silc_server_packet_send_to_channel. Affected file is
2785 silcd/packet_send.c.
2787 * Fixed silc_server_send_notify_dest to set the broadcast
2788 flag. Fixed the silc_server_send_notify_topic to actually
2789 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2790 Affected file silcd/packet_send.c.
2792 * Changed the SFTP Filesystem interface. Changed the
2793 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2794 the filesystem operation function. The SilcSFTPFilesystem
2795 is now a context that is allocated by all filesystem allocation
2796 functions and it already includes the operations structure
2797 and filesystem specific context. It is given as argument
2798 now to the silc_sftp_server_start. This made the interface
2799 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2800 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2802 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2804 * Changed the backup router adding and getting interfaces
2805 in the server. The router that will be replaced by the
2806 specified backup router is now sent as argument. Affected
2807 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2810 * Added silc_net_addr2bin_ne to return the binary form of
2811 the IP address in network byte order. Affected files
2812 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2814 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * Check for existing server ID in silc_server_new_server
2817 and in silc_server_connect_to_router_final and remove the
2818 old entry if it exists. Affected file silcd/packet_receive.c,
2821 * Send the channel message always to only one router, either
2822 in upstream or downstream. Affected file is
2823 silcd/packet_send.c.
2825 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Wrote the definition of the backup resuming protocol to the
2828 protocol specification.
2830 * Removed one redundant channel key generation from normal
2831 server during joining procedure. Removed one redundant
2832 channel key sending from server to router during joining
2833 procedure. Affected file silcd/command.c.
2835 * Made minor bugfixes to the backup router resuming protocol.
2836 Affected file silcd/server_backup.c, server.c.
2838 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * Added --disable-asm configuration option. Affected files
2841 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2844 * Implemented the backup resuming protocol that is used to
2845 resume the primary router position in the cell after the
2846 primary router comes back online. Affected files
2847 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2848 and silcd/server_util.[ch].
2850 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * Sleep two (2) seconds after sending QUIT command to server.
2853 Affected file lib/silcclient/command.c.
2855 * Assure that if outgoing data buffer is pending do not force
2856 send any data. Affected file silcd/packet_send.c.
2858 * Assure that if outgoing data buffer is pending do not force
2859 send any data. Affected file lib/silcclient/client.c.
2861 * Implemented the backup router support when the primary router
2862 goes down. The servers and routers can now use the backup
2863 router as new primary router without loosing connectivity.
2865 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2868 in the server to indicate disabled entry. All data read
2869 from the connection will be ignored and no data is sent
2870 for entry that is disabled. Affected files are
2871 silcd/idlist.h, silcd/server.c.
2873 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Created SFTP client and server test programs in the
2876 lib/silcsftp/tests directory.
2878 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Implemented memory filesystem (virtual filesystem) for
2881 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2884 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Implemented the SFTP (SSH File Transfer Protocol) to the
2887 lib/silcsftp. It includes SFTP client and SFTP server
2890 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Moved lib/silccore/silcprotocol.[ch] to the
2893 lib/silcutil library.
2895 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2896 take variable argument list pointer as argument. Affected
2897 file lib/silcutil/silcbuffmt.[ch].
2899 * Added silc_buffer_set function that is used to set data
2900 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2901 Affected file lib/silcutil/silcbuffer.h.
2903 * Changed various routines in the core library to use the new
2904 silc_buffer_set instead of allocating new buffer only for
2907 * Added 64-bit value formatting and unformatting support to the
2908 silc_buffer_[un]format routines. Affected file is
2909 lib/silcutil/silcbuffmt.[ch].
2911 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2912 to includes/bitmove.h.
2914 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Fixed channel user mode saving in client library. Affected
2917 file lib/silcclient/command[_reply].c.
2919 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2921 * Defined the file transfer to the SILC Protocol. Added
2922 new packet type SILC_PACKET_FTP and defined File Transfer
2923 Payload. The mandatory file transfer protocol is SFTP
2924 (SSH File Transfer Protocol). Affected file in addition
2925 of the internet draft is lib/silccore/silcpacket.h.
2927 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2928 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2929 is used as part of backup router protocol when the primary
2930 router of the cell is back online and wishes to resume
2931 the position as primary router.
2933 * Redefined the MAC generation keys in the protocol. The
2934 same key is not used anymore in both direction. Both
2935 direction will now use different keys for sending and
2936 receiving. This fixes a potential security flaw. This
2937 change causes incompatibilities in the protocol.
2939 * Redefined also the MAC computation from the packet.
2940 An packet sequence number is now added to the MAC
2941 computation. This prevents possible replay attacks against
2942 the protocol. This change too causes incompatibilities
2945 Added `sequence' field to the SilcPacketContext to hold
2946 the current sequence number for the packet.
2948 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2950 * Added `created' field to the SilcIDListData in the file
2951 silcd/idlist.h to indicate the time when the entry was
2954 * Added `created' field to the SilcChannelEntry too. Affected
2955 file silcd/idlist.h.
2957 * Added `creation_time' aguments to all the announcement functions
2958 in the server. If it is provided then only the entries that
2959 was created after the provided time frame are actually
2960 announced. Affected file silcd/server.[ch].
2962 * The protocol says that the Channel ID's IP address must be
2963 based on the router's IP address. Added check for this in
2964 the silc_server_new_channel when processing incoming New Channel
2965 Payload. Affected file silcd/packet_receive.c.
2967 * Print out the correct version with --version in SILC client.
2968 Affected file irssi/src/silc/core/silc-core.c.
2970 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2972 * Fixed WHOWAS command to check for completnes of the client
2973 entry always, not just when the command is coming from client.
2974 Affected file silcd/command.c.
2976 * Added new function silc_server_packet_queue_purge to purge the
2977 outgoing data queue to the network. After the function returns
2978 it is guaranteed that the outgoing packet queue is empty.
2979 Affected file silcd/packet_send.[ch].
2981 * Purge the outgoing packet queue in the rekey protocol's final
2982 callback to assure that all rekey packets go to the network
2983 before quitting the protocol. Affected file silcd/server.c.
2985 * Added silc_client_packet_queue_parse as similar function as
2986 in server to the client library. The affected file is
2987 lib/silcclient/client.c.
2989 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Splitted silcd/server.c and created silcd/server_util.[ch]
2992 for utility functions.
2994 * Added new socket flag SILC_SF_DISABLED to indicate that the
2995 connection is open but nothing can be sent to or received from
2996 the connection. Affected file lib/silcutil/silsockconn.[ch].
2997 The checking for disabled socket is checked in the low level
2998 silc_socket_write and silc_socket_read functions.
3000 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Allow only nicknames and channel names that fits into the
3003 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3005 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * When processing JOIN command reply in server check that if
3008 the channel exists in our global list we'll move it the local
3009 list. Affected file silcd/command_reply.c.
3011 * Fixed the check whether client is joined on the channel already
3012 in JOIN command. Affected file lib/silcclient/command.c.
3014 * Fixed the JOIN command reply to check whether the channel
3015 already exists. Affected file lib/silcclient/command_reply.c.
3017 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Added silc_ske_status_string to map the SKE error numbers
3020 to readable strings. The affected files are
3021 lib/silcske/silcske[_status].[ch].
3023 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Do not show the private channels on the WHOIS channel list
3026 as it is not allowed by the protocol. The affected file is
3029 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Assure that the packet length digged from the actual packet
3032 is something sensible in the silc_packet_decrypt_rest_special
3033 in lib/silccrypt/silcpacket.c.
3035 * Free and NULL the allocated pointer in silc_hmac_alloc if
3036 the HMAC allocation fails. The affected file is
3037 lib/silccrypt/silchmac.c.
3039 * Print the selected security properties to the log files in
3040 the server. Affected file silcd/protocol.c.
3042 * Add SKE's reference counter even if calling the completion
3043 callback manually. Otherwise it goes negative, although it
3044 does not cause any problems. The affected file is
3045 lib/silcske/silcske.c.
3047 * Remove the client entry with short timeout after giving the
3048 KILL command. Affected file lib/silcclient/command.c.
3050 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3051 case all found clients are already disconnected (WHOWAS would
3052 found them) in the server. Affected file silcd/command.c.
3054 * Update the last_receive (time of last data received) to be
3055 updated only when received private or channel message so that
3056 the idle time showed in WHOIS makes more sense.
3058 * Added boolean field `valid' in to the SilcClientEntry in the
3059 client library to indicate whether the entry is valid or not.
3060 This fixes the nickname change bug on channel when changing
3061 the nickname to be same than the old (like nick to Nick) the
3062 nickname formatter doesn't set the new nick anymore to Nick@host.
3063 Affected file lib/silcclient/idlist.[ch].
3065 * Now actually fixed the nickname changing on disconnection.
3066 Added new function silc_change_nick to the Irssi SILC Client.
3067 Affected file irssi/src/silc/core/client_ops.c,
3068 irssi/src/silc/core/silc-nicklist.[ch].
3070 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Check that the public key exists in the GETKEY command before
3073 trying to encode it. Affected file silcd/command.c.
3075 * Print some notifications on received public keys with GETKEY
3076 command in the Irssi SILC Client. Affected files are
3077 irssi/src/fe-common/silc/module-formats.[ch],
3078 irssi/src/silc/core/client_ops.c.
3080 * Use IDENTIFY command to resolve the server information in the
3081 GETKEY command instead of INFO command. Affected file
3082 lib/silcclient/command.c.
3084 * All command reply functions in the client library now calls
3085 the pending command reply callbacks even if an error has
3086 occurred. The server has done this a long time and now it was
3087 time to move the client library to this as well. Now all
3088 errors can be delivered back to the pending command reply
3089 callbacks if necessary. Affected files are
3090 lib/silcclient/command[_reply].[ch].
3092 * Change the nickname on disconnection back to the username
3093 because in reconnect the server will enforce it to it anyway.
3094 Affected file irssi/src/silc/core/silc-servers.c.
3096 * Fixed a config file parsing bug in the Irssi SILC client.
3097 Affected file irssi/src/silc/core/clientconfig.c.
3099 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * When printing the channel mode on JOIN, verify that the
3102 channel key and channel's HMAC are valid. Affected file
3103 irssi/src/silc/core/client_ops.c.
3105 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3108 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3109 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3111 * Removed channel key rekey task deleting from the function
3112 silc_server_save_channel_key. Affected file silcd/server.c.
3113 Added explicit timeout task context instead that is used to
3114 delete the task if we are registering a new task before the
3115 new task has elapsed.
3117 * When channel key rekey occurs the client library now saves
3118 the old channel key for a short period of time (10 seconds) and
3119 is able to use it in case some is still sending channel
3120 messages encrypted with the old key after the rekey. Affected
3121 file lib/silcclient/[idlist.h|client_channel.c].
3123 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Added check to the silc_server_new_id_real to not accept
3126 new ID if it is the sender's own ID. Affected file is
3127 silcd/packet_receive.c.
3129 * Assure that we do not announce ourself or the one we've
3130 sending our announcements when we're router and are announcing
3131 servers to our primary router. Affected file silcd/server.c.
3133 * Fixed silc_server_command_identify_check_client to assemble
3134 correct WHOIS packet. It send corrupted WHOIS packet and
3135 caused problem with router to router connections. Affected
3136 file silcd/command.c.
3138 Fixed also silc_server_command_whois_check the same way
3139 as for the IDENTIFY command.
3141 * Added new SilcIDListStatus to the server in the SilcIDListData
3142 structure. The status now includes the current status of
3143 the entry (like registered, resolved etc.). Affected file
3144 silcd/idlist.[ch]. Defined a bunch of different status types
3145 as well. This replaced the old boolean registered field as well.
3147 Added resolve_cmd_ident field to the SilcClientEntry structure
3148 too so that if the entry is for example being resolved so
3149 another command may attach to the same pending command reply
3150 without requiring to resolve the same entry again. This concept
3151 should optimize the WHOIS and the IDENTIFY resolving under
3152 heavy load by taking away unnecessary resolving for entries
3153 that are being resolved already.
3155 Added support for adding multiple pending commands for one
3156 command idenfier. Affected file silcd/command[_reply].[ch].
3158 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3159 before deleting the data. Otherwise the hash table will have
3160 freed data in comparison functions. Affected file is
3161 silcd/command_reply.c.
3163 * Fixed silc_idlist_replace_client_id to add the new entry to
3164 the cache with NULL nickname. Otherwise there will be invalid
3165 memory as the nickname after the nickname is freed. Affected
3166 file silcd/packet_receive.c.
3168 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3169 saved into wrong slots because the previous number of entries
3170 was not taken into account. Affected file silcd/idlist.c.
3171 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3173 * If we are router and we receive JOIN notify to a channel that
3174 does not have any users then notified client is marked as the
3175 channel founder, as it is it. The affected file is
3176 silcd/packet_receive.c
3178 * Added to the extended hash table API's table_del_*ext functions
3179 the destructor as argument too, so that the caller can decide
3180 which destructor to use or whether to use destructor at all.
3181 Affected file lib/silcutil/silchashtable.[ch].
3183 * Fixed ID Cache purging. It actually deleted the entries from
3184 the hash table after the data was freed. The hash table ended
3185 up comparing freed memory. The affected file is
3186 lib/silccore/silcidcache.c.
3188 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * Fixed Irssi SILC client's KILL command's HELP syntax.
3192 * The USERS command now resolves the detailed user information
3193 if the userinfo field is missing. Affected file is
3194 lib/silcclient/command_reply.c.
3196 * Do not print error in silc_file_read if the read file does
3197 not exist. Just silently return NULL. Affected file is
3198 lib/silcutil/silcutil.c.
3200 * Fixed the silc_log_output to not wine about NULL filename
3201 and to not create some bogus " " filename. Affected file is
3202 lib/silcutil/silclog.c.
3204 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Fixed various printing bugs on the user interface in the
3207 Irssi SILC Client. Minor changes that were forgotten from
3210 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Fixed the configure.in.pre and the compilation and distribution
3213 environment to support the new autoconf 2.52. That version is
3214 now required to compile the CVS trunk.
3216 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3218 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3219 to generally parse user@fqdn format strings. Affected file
3220 lib/silcutil/silcutil.c.
3222 * Added nickname_format and nickname_force_format fields to the
3223 SilcClientParams structure. The first one defines the format
3224 for the nicknames that the library will enforce if the receives
3225 multiple same nicknames. The second one is boolean value and
3226 can be used to force the library to always enforce the format
3227 to the nicknames regardles whether there are multiple nicknames
3228 or not. This configurable formatting was employed to flexibly
3229 support accessing multiple nicknames from the user interface.
3230 The userinterface can now set the nicknames to what ever format
3231 they prefer. Affected file lib/silcclient/silcapi.h.
3233 Added function silc_client_nickname_format to the file
3234 lib/silcclient/idlist.c. It performs the nickname formatting.
3236 Added new field `hostname´ to the SilcClientEntry context.
3237 It holds the hostname of the client. Affected file is
3238 lib/silcclient/idlist.h.
3240 * Irssi SILC Client sets the nicknames in nick@hostn format.
3241 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3242 irssi/src/silc/core/silc-core.c.
3244 The WHOIS printing now also shows both the real nickname and
3245 the formatted nickname so that user knows how to access the
3246 user if there are multiple same nicknames cached. Affected
3247 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3248 printing formatting too to take the hostname now as a separate
3249 argument. The Affected file is
3250 irssi/src/fe-common/silc/modules-formats.[ch].
3252 * Changed the silc_client_get_clients_local to accept the formatted
3253 nickname as argument. It accepts the real nickname too but the
3254 formatted nickname can be used to find the true entry from
3255 multiple entries. Affected file lib/silcclient/silcapi.h and
3256 lib/silcclient/idlist.c.
3258 * Added nickname_format_parse field to the SilcClientParams.
3259 It is a callback function provided by the application to parse
3260 the nickname out of the formatted nickname string. The library
3261 calls it to get the nickname from the formatted string. Since
3262 the application generally knows better the format of the nickname
3263 string it parses it instead of the library, even though library
3264 encodes the formatted string. If the callback function is not
3265 provided then the library will use the string as is. The
3266 affected file is lib/silcclient/silcapi.h.
3268 * All the nickname strings passed to the client library in
3269 commands are now expected to be formatted nickname strings.
3270 If the command does not support the formatted nickname string
3271 it will assume that the sent string is the actual nickname.
3272 Affected file lib/silcclient/command.c.
3274 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Added public key authentication support to OPER and SILCOPER
3277 commands in the client library. Affected file is
3278 lib/silcclient/command.c.
3280 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Changed the get_auth_methdod client operation to be asynchronous.
3283 It can be async if the application resolves the authentication
3284 method from the server during the negotiation. Added new
3285 SilcGetAuthMeth completion callback that the application will
3286 call after resolving the authentication method.
3288 Added function silc_client_request_authentication_method that
3289 the application can use to resolve the authentication method
3290 from the server. Added also SilcConnectionAuthRequest callback
3291 that the library will call after the server has replied. The
3292 application can call this function if it does not know the
3293 current authentication method.
3295 Affected files are lib/silcclient/client.c and
3296 lib/silcclient/silcapi.h.
3298 * The Irssi SILC client now automatically resolves the authentication
3299 method incase any configuration information is not present (and
3300 currently there never is). The affected file is
3301 irssi/src/silc/core/client_ops.c.
3303 * Fixed public key authentication from the client library.
3304 Affected file lib/silcclient/protocol.c. Changed also the
3305 protocol specification about the public key authentication in
3306 the connection authentication protocol. The actual data to be
3307 signed is now computed with a hash function before signing.
3309 * Fixed the public key authentication from the server as well.
3310 Affected file silcd/protocol.c.
3312 * Removed the mlock()'s from the memory allocation routines.
3313 Affected file lib/silcutil/silcmemory.c. The ./configure does
3314 not check anymore for the mlock(). Affected file is
3317 * Fixed USERS command in server to allow the execution of the
3318 command for private and secret channels if the client sending
3319 the command is on the channel. Affected file silcd/command.c.
3321 * Fixed silc_client_get_clients_local to return the clients
3322 count correctly. It could return wrong value. Affected file
3323 lib/silcclient/idlist.c.
3325 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3328 types. The assembler optimizations seemed not to like 64-bit
3329 data types. The assmebler optimizations thus are now enabled
3330 also for BSD systems as opposed to only enable them for Linux.
3332 * Do not check for threads at all on BSD systems. Affected
3333 file configure.in.pre.
3335 * Removed -n and -h options from the Irssi SILC Client since
3336 they are not used in silc.
3338 * Fixed the prime generation to assure that the first digit
3339 of the generated random number is not zero since our conversion
3340 routines does not like number strings that starts with zero
3341 digit. If zero digit is seen the random number is regenerated.
3342 This caused some corrupted RSA keys when the zero first digit
3343 was met. Affected file lib/silcmath/silcprimegen.c.
3345 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Fixed WIN32 configuration in the ./configure script.
3348 Fixed to include xti.h on environments that has it.
3349 Patches by Carsten Ilchmann and andrew.
3351 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3353 * Changed the silc_id_create_client_id to be collision
3354 resistant. It is now assured that there cannot be created
3355 two same client ID's. I suspect that some weird bugs in
3356 the server were actually caused by duplicate Client IDs.
3357 Affected file silcd/serverid.[ch]. A router receiving
3358 new ID now also assures and informs the sending server
3359 if the ID caused collision.
3361 * Changed the silc_id_create_channel_id to also assure that
3362 there are no collisions.
3364 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3366 * Statement about ignoring the Mutual Authentication flag when
3367 performing rekey with PFS was a bit misleading. It is ignored
3368 if it was set in the initial negotiation, it cannot be even
3369 set in the rekey. Fixed in the ke-auth draft. Started the
3370 new versions of the protocol drafts in the doc/.
3372 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Fixed a bug in silc_client_command_identify_save when saving
3375 new channel information. The channel name was no duplicated
3376 and caused crash on exit. Affected file is
3377 lib/silcclient/command_reply.c.
3379 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Fixed the getkey command handling in the server. Send just
3382 empty OK reply to the sender if the key could not be fetched
3383 (but everything else was ok, like the key just was not available).
3384 Changed the public key parameter to optional in the protocol
3385 specs so that empty OK reply can be sent. Affected file
3388 Added a message to Irssi SILC client to tell to user if the
3389 server did not return a public key.
3391 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Fixed a channel key regeneration bug. It registered new
3394 timeout tasks exponentially until all system resources were
3395 used. Affected file silcd/server.c.
3397 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3399 * Added the SILC Document generator to the scripts/silcdoc.
3400 It can be used to generate the Toolkit Reference Manual out
3401 of the source tree. Internally it will also use the RoboDoc
3402 generator now imported in util/robodoc.
3404 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3406 * Added couple of return's in rekey protocol if error orccurred
3407 during the protocol. The execution must be terminated.
3408 Affected file silcd/protocol.c. Also, terminate the protocol
3409 always with timeout.
3411 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * The client's Client ID was created initally from the wrong
3414 nickname (it could have been in format nick@host) in the
3415 silc_server_new_client. Affected file silcd/packet_receive.c
3417 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3419 * Added some SILC_LOG_ERROR's to various error conditions
3420 if client could not be added to ID cache. Affected files
3421 silcd/packet_receive.c and silcd/server.c.
3423 * When client's sock->user_data is freed, NULL also the
3424 client->router and client->connection pointers. Added check
3425 for these pointers being NULL to various places around the
3426 code. Affected file silcd/server.c.
3428 * Added client->data.registered == TRUE checks to various
3429 places around the code to assure that unregistered client's
3430 are not handled when it is not allowed. Affected file
3433 * Added `bool registered' fields to all
3434 silc_idlist_[server|client]_get_* routines to indicate whether
3435 the fetched client needs to be registered or not. Affected
3436 file silcd/idlist.[ch].
3438 * Add your own entry as registered to the ID cache in the
3439 server. Affected file server.c.
3441 * Fixed a bug in silc_server_new_server. The SilcServer was
3442 set as the new server's context instead of SilcServerEntry.
3443 This naturally caused some weird bugs.
3445 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Do not delete the channel rekey task when adding it
3448 for in silc_server_create_channel_key.
3450 * Changed the silc_server_create_channel_key to return
3451 TRUE or FALSE to indicate the success of the channel key
3454 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Fixed MSVC++ project files and added missing files to
3457 Makefiles under win32/.
3459 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Do not add TCP_NODELAY flag if the operating system
3462 does not have it defined. Affected files are
3463 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3465 * Fixed buffer overflow from Irssi SILC Client. Affected
3466 file irssi/src/fe-common/core/themes.c.
3468 * Fixed double free in client library in the file
3469 lib/silcclient/client.c when disconnecting from server.
3471 * Applied double free patch from cras to Irssi SILC client.
3472 Affected files irssi/src/core/[modules/expandos].c
3474 * Fixed the disconnection handling to Irssi SILC Client.
3475 The application must call silc_client_close_connection
3476 in ops->connect client operation in case of failure of
3477 the connection. Affected file is
3478 irssi/src/silc/core/client_ops.c.
3480 * Do not set sock->protocol to NULL in the function
3481 silc_client_close_connection after executing the protocol's
3482 final callback since the sock might not be valid anymore.
3483 Affected file lib/silcclient/client.c.
3485 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Do not enable SILC_THREADS if the linking with libpthread
3488 did not happen. Affected file configure.in.pre.
3490 * Added notion to protocol specification that server must
3491 verify the sent authentication payload with CMODE when
3492 setting the channel founder key. Implemented it to the
3493 server. Affected file silcd/command.c.
3495 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * Added _EXTRA_DIST SILC distribution variable to the
3498 distributions file. It is used to conditionally add extra
3499 files or directories to the specific distribution. Affected
3500 files ./prepare, Makefile.am.pre and distributions.
3502 Removed the `_' from the start of the distribution names.
3505 * Added README.WIN32 for instructions to compile the Toolkit
3508 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Fixed a double free in disconnection in the server. Affected
3511 file is silcd/server.c.
3513 * Fixed the lib/silcske/groups.c to work now also with GMP
3514 MP library. The string conversion did not work when using
3515 specific base and the base is indicated in the string as well.
3517 * Created win32/ directory which now includes MSVC++ specific
3518 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3519 It will appear only in the toolkit distribution
3521 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * Changed the key material distribution function in case when
3524 the hash output is too short. The data is now concatenated
3525 a bit differently than it used to. Made the change to the
3526 SKE protocol specification.
3528 * Added better GMP detection to configure.in.pre. A patch
3531 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Fixed a minor bug in SKE that might cause some problem on
3534 some platforms. Affected file lib/silcske/silcske.c.
3536 * Added the cookie checking for initiator in the SKE. It checks
3537 that the responder returns the sent cookie unmodified. The
3538 affected file is lib/silcske/silcske.c. Added new SKE
3539 error type INVALID_COOKIE that can be sent during the
3540 negotiation. Fixed some memory leaks as well.
3542 * Added the "invalid cookie" error message to Irssi SILC client's
3545 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * Added `task_max' field to the SilcClientParams to indicate
3548 the maximum tasks the scheduler can handle. If set to zero,
3549 default values are used. Affected file lib/silcclient/silcapi.h.
3551 * Fixed memory leaks in silc_client_close_connection. Affected
3552 file lib/silcclient/client.c.
3554 * Added silc_client_del_client_entry to client library to free
3555 all memory of given client entry. Affected file is
3556 lib/silcclient/idlist.[ch].
3558 * Added new functions silc_client_del_channel and
3559 silc_client_del_server to delete channel and server entries.
3560 Affected file lib/silcclient/[silcapi.h/idlist.c].
3562 * Removed silc_client_del_client_by_id from silcapi.h.
3564 * Fixed the INFO command to return the server's own info
3565 correctly when querying by Server ID. Affected file is
3568 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Removed the non-blocking settings in WIN32 code in the
3571 silc_sock_[read/write] and added SleepEx instead. Affected
3572 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3573 of input data is now checked with FIONREAD and ioctlsocket.
3575 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3577 * Call silc_schedule_task_del_by_context in the
3578 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3579 Affected file lib/silccore/silcprotocol.c.
3581 * Call silc_protocol_cancel for active protocols in the
3582 silc_server_close_connection if the funtion
3583 silc_server_free_sock_user_data has not been called.
3584 Affected file silcd/server.c.
3586 * Generic tasks cannot be deleted using the del_by_fd
3587 task deleting function since generic tasks does not match
3588 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3590 * Added a notion to SILCOPER help file that the SILCOPER works
3591 only on router server, not on normal server.
3593 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Added for WIN32 support for the new scheduler as well.
3596 Affected file lib/silcutil/win32/silcwin32schedule.c.
3598 * Fixed the SHA1 implementation to work on various platforms.
3600 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3603 API. It is part of the scheduler now. Everything else is
3604 as previously but some functions has changed their names.
3605 Checkout the lib/silcutil/silcschedule.h for the interface.
3606 Updated all applications to use the new interface. Affected
3607 files are lib/silcutil/silcschedule.[ch].
3609 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3611 * Found a bug in the SKE implementation. The HASH value,
3612 specified by the protocol, was not computed correctly. The
3613 public key of the responder was not added to the computation
3614 even though it is mandatory. Affected file lib/silcske/silcske.c.
3615 This unfortunately causes incompatibilities with older
3616 clients and servers.
3618 * Added WIN32 specific network init and uninit functions:
3619 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3620 the Winsock2. Affected file lib/silcutil/silcnet.h and
3621 lib/silcutil/win32/silcwin32net.c.
3623 * Set the socket always to nonblocking mode on WIN32 after
3624 reading data or writing data. Affected file is
3625 lib/silcutil/win32/silcwin32sockconn.c.
3627 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Fixed various compilation problems under WIN32. Affected
3630 files lib/silcutil/win32/silcwin32thread.c and
3631 lib/silcutil/win32/silcwin32schedule.c.
3633 * Removed all _internal.h #includes from public header
3634 files. Internal headers must never be included from
3637 Removed also the lib/silcske/payload_internal.h file.
3639 * All include files that may be needed (public and some others
3640 included by the public headers) by application developers are
3641 now copied to the ./includes directory. It does not copy any
3642 internal headers. Affected file Makefile.defines.pre and all
3643 Makefile.am's under lib/ and subdirs.
3645 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3647 * Do not change the ~/.silc directory's permissions automatically.
3648 Affected file irssi/src/silc/core/clientutil.c.
3650 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3652 * Do not cancel the protocol in silc_server_close_connection
3653 it might cause recursion. Now cancelled in the function
3654 silc_server_free_sock_user_data. Affected file silcd/server.c.
3656 * Fixed the silc_server_remove_clients_by_server to regenerate
3657 the channel keys correctly finally. Added also new function
3658 silc_server_remove_clients_channels to actually do it.
3659 Affected file silcd/server.c.
3661 * Fixed the silc_server_new_channel to not crash by giving
3662 wrong router to the new channel. Affected file is
3663 silcd/packet_receive.c.
3665 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3667 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3668 which is given as argument to the silc_client_alloc now.
3669 It can be used to configure the client and set various parameters
3670 that affect the function of the client.
3672 * The USERS command in server did not check whether the channel
3673 is private or secret. Affected file silcd/command.c.
3675 * Added new argument to the USERS command in protocol specification.
3676 The USERS command now can take the channel name as argument
3677 as well. Added support for this in client and server and
3678 updated the protocol specs.
3680 * Completed the GETKEY command in client. It can be now used
3681 to fetch also servers public key not only some clients.
3682 Affected files lib/silcclient/command[_reply].c.
3684 * Added silc_client_get_server to return server entry by the
3685 server name. Affected files lib/silcclient/silcapi.h and
3688 * Redefined the IDENTIFY command in protocol specification to be
3689 more generic. It now can be used to query information about
3690 any entity in the SILC Network, including clients, servers and
3691 channels. The query may be based either the entity's name
3692 or the ID. Added support for this in both client and server.
3694 Affected files silcd/command.c and lib/silcclient/command.c
3695 and command_reply.c.
3697 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3698 the _from_client and _from_server functions. Affected file
3701 * Added silc_client_get_channel_by_id_resolve to the file
3702 lib/silcclient/silcapi.h to resolve channel information by
3703 its ID. Added also silc_client_get_channel_by_id that
3704 does not resolve it from the server.
3706 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Added SilcServerEntry context into the client library
3709 to represent one server. The INFO command now allocates
3710 these to save the resolved server info. For now on the
3711 client library will also keep information about servers,
3712 connected and resolved with INFO.
3714 The INFO command now allocates the SilcServerEntry context
3715 and saves the server info there. The COMMAND_REPLY in
3716 the INFO now returns the parameters to application in
3717 same order as defined in the protocol specification.
3719 The entries are cached in the client->server_cache.
3721 * The INFO command is now issued after received the Client ID
3722 from the server. Affected file lib/silcclient/client.c.
3724 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3725 to the application as the mode changer might be server.
3726 It is guaranteed that NULL is not returned anymore to the
3727 application. Affected file lib/silcclient/client_notify.c.
3729 The ID Type is now also passed to the application so that
3730 it can check whether the returned entry is SilcClientEntry
3733 Added new function silc_client_get_server_by_id to return
3734 the server entry by ID. Affected files are the
3735 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3737 * Do not create the channel in the Irssi SILC Client when issuing
3738 the JOIN command but when received the sucessful JOIN command
3739 reply. Otherwise the channel might get created even though we
3740 could not join it. The Affected file is
3741 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3743 * Fixed a channel joining bug in router. The router must also
3744 check the channel modes, invite and ban lists etc. when serving
3745 the JOIN command sent by normal server. Affected file is
3746 silcd/command.c. The router now resolves the client's
3747 information from the server who sent the JOIN command if it
3748 does not know it, and processes the JOIN command only after
3751 * Changed the SilcCommandCb to take new argument; void *context2.
3752 Affected file lib/silccore/silccommand.h
3754 The second argument in the command callbacks in the server now
3755 includes the SilcServerCommandReplyContext if the command was
3756 called as pending command callback from the command reply.
3757 Otherwise it is NULL. When called as pending the status of the
3758 command reply will be checked and if it was erronous the
3759 error will be sent to the original sender of the command.
3760 This way the client always receives the error messages even
3761 though the server was actually the one who received the error
3762 when it resent the command to router, for example. Affected
3763 files silcd/command[_reply].[ch].
3765 * Fixed sending WHOWAS command's error message to client if
3766 the requested client could not be found. It was missing.
3769 * Changed the CMODE and CUMODE commands reply arguments in the
3770 protocol specification. The Channel ID is now sent in both
3771 of the commands to identify the channel. Implemented this
3772 new feature to the client and server. Affected files
3773 lib/silcclient/command_reply.c and silcd/command.c.
3775 * Made better checks for invite and ban lists in the JOIN
3776 command in server. Affected file silcd/command.c.
3778 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3780 * The server now performs the incoming host IP/DNS lookup
3781 using the silc_socket_host_lookup and thus does not block
3782 the server anymore. Affected file silcd/server.c.
3784 * Completed the multi-thread support for SILC Scheduler in
3785 the lib/silcutil/silcschedule.c.
3787 * Fixed the configure.in.pre to detect the pthread correctly
3790 * Fixed a deadlock in silc_task_queue_wakeup in the file
3791 lib/silcutil/silctask.c.
3793 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Added new function silc_schedule_wakeup that is used in
3796 multi-threaded environment to wakeup the main thread's
3797 schduler. It needs to be used when a thread adds a new task
3798 or removes a task from task queues. After waking up, the
3799 scheduler will detect the task queue changes. If threads
3800 support is not compiled in this function has no effect.
3801 Implemented the wakeup mechanism to both Unix and WIN32
3802 systems. Affected files are lib/silcutil/silcschedule.[ch],
3803 lib/silcutil/unix/silcunixschedule.c and the
3804 lib/silcutil/win32/silcwin32schedule.c.
3806 * Added new function silc_task_queue_wakeup to wakeup the
3807 scheduler by the specified task queue. Affected file
3808 lib/silcutil/silctask.[ch].
3810 * The silc_socket_host_lookup_start now wakes up the scheduler
3811 after adding the timeout task. Affected file is
3812 lib/silcutil/silcsockconn.c.
3814 * The silc_socket_host_lookup is synchronous now if the threads
3815 support is not compiled in. However, the callback is still
3816 called asyncronously through the scheduler, anyway. Affected
3817 file lib/silcutil/silcsockconn.c.
3819 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Added new function silc_socket_host_lookup to perform
3822 asynchronous IP and FQDN lookups for the socket connection.
3823 Affected files lib/silcutil/silcsockconn.[ch].
3825 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3827 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3828 that may or may not compile the mutex support in.
3830 Changed the silc_mutex_alloc interface. It allocates the
3831 mutex now to the sent pointer and returns TRUE or FALSE.
3833 Affected file lib/silcutil/silcmutex.h.
3835 * Wrote the SILC Task Queue interface to support multi-threads.
3836 Affected file lib/silcutil/silctask.[ch].
3838 * Wrote the SILC Scheduler to support multi-threads. Affected
3839 file lib/silcutil/silcschedule.c.
3841 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3843 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3844 in lib/silcutil/win32/.
3846 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3848 * Defined SILC Mutex API and SILC Thread API and implemented
3849 them for Unix. Affected files are
3850 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3851 lib/silcutil/unix/silcunixmutex.c and
3852 lib/silcutil/unix/silcunixthread.c.
3854 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Fixed the silc_server_remove_clients_by_server's channel
3857 key re-generation. The hash table handling was incorrect
3858 and would not work with many channels. Affected file is
3861 * Fixed some memory leaks around the server code.
3863 * Rewrote the silc_server_get_users_on_channel to support IPv6
3864 based Client ID's. Affected file silcd/server.c.
3866 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3867 specification. However, a separate document must be written
3868 to define the detailed signing procedure and the payload
3869 associated with the flag. Defined the flag to the
3870 lib/silccore/silcchannel.h as well.
3872 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Changed the dynamic tables to static size tables in the
3875 lib/silccrypt/silchmac.c.
3877 * Removed GCC dependencies from the code. A patch by cras.
3879 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Do not show the error "Error receiving packet bla bla"
3882 in server if it really was not an error (-2 means that reading
3883 is pending). Affected file silcd/server.c.
3885 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * Fixed a possible crash in silc_server_remove_clients_by_server
3888 in silcd/server.c. Fixed there also some memory leaks.
3890 * Fixed the silc_idlist_replace_client_id. It could replace
3891 wrong key in the hash table. Affected file silcd/idlist.c.
3893 * Do not check whether there are global users on the channel
3894 if the channel->global_users is FALSE. Affected functions
3895 silc_server_remove_from_one_channel and
3896 silc_server_remove_from_channels in silcd/server.c. Also,
3897 do not check if the removed client is local as we can be
3898 sure that global client was not removed from the channel
3899 and checking for global users is not needed.
3901 * The silc_server_remove_clients_by_server now re-generates
3902 the channel keys correctly for those channels that had
3903 clients removed from them. Affected file silcd/server.c.
3905 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3907 * Found the reason of random crashes in the server. We weren't
3908 ignoring the SIGPIPE signal (which can be sent in write())
3909 and it crashed the server. Affected file silcd/silcd.c.
3911 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3913 * Assure that sock->user_data is not NULL in the function
3914 silc_server_packet_send in silcd/packet_send.c.
3916 * Disconnect the remote connection if it could not be added
3917 to any ID lists in the server. The affected file is
3920 * Check in silc_server_packet_send[_real/dest] that the
3921 socket is not disconnecting and ignore the data if it is.
3922 Affected file silcd/packet_send.c.
3924 * Define inline to __inline on native WIN32 compilation.
3925 Affected file includes/silcwin32.h.
3927 * Added some explicit type casts for inline code since MSVC
3928 require them. Affected files lib/silcutil/silcbuffer.h,
3929 lib/trq/silcdlist.h and lib/trq/silclist.h.
3931 * Print warning in log files from now on if the packet
3932 decryption fails. Affected file silcd/server.c.
3934 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3936 * Changed the `say' client operation's interface to accept
3937 new `type' argument to indicate the type of the message sent
3938 by the library. The application may filter the library's
3939 messages according the type. The affected file is the
3940 lib/silcclient/silcapi.h.
3942 * Added two new functions to lib/silcclient/silcapi.h:
3943 silc_client_del_client and silc_client_del_client_by_id.
3944 Affected file lib/silcclient/idlist.c.
3946 * Moved the clientincludes.h from includes/ to silc/ and
3947 serverincludes.h from includes/ to silcd/.
3949 * The modes for the CMODE and CUMODE are now passed as
3950 uint32 for application with COMMAND_REPLY. The affected
3951 file is lib/silcclient/command_reply.c.
3953 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3955 * /WHOIS without arguments shows client's own information.
3956 Affected file lib/silcclient/command.c.
3958 * Changed PING to not accept any arguments. The specs
3959 says that client can ping only the connected server so
3960 requiring an argument is not needed. Affected file is
3961 lib/silcclient/command.c.
3963 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3965 * Fixed a fatal bug in private message sending and reception
3966 encryption and decryption when using private message keys.
3967 The implementation was incorrect and did not follow the
3968 specification. It causd that some of the message were
3969 lost since it did not use the sending and receiving keys
3970 as the protocol suggests. This has been fixed and will cause
3971 incompatibilities with older clients when sending private
3972 message encrypted with private message keys. Affected files
3973 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3974 and various other in Irssi SILC Client.
3976 Added `responder' boolean argument to the functions
3977 silc_client_add_private_message_key[_ske] to indicate when
3978 the key is added as responder or initiator of the key
3981 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3983 * Removed the silc_ske_check_version function and created
3984 a SilcSKECheckVersion callback. Added also a function
3985 silc_ske_set_callbacks that is now used to set all SKE
3986 callbacks. The callback functions are not given to
3987 the SKE functions anymore, but this function is used to
3990 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3992 * Added `silc_version' argument to the silc_client_alloc
3993 to define the version of the application for the library.
3994 The library will use the version string to compare it
3995 against the remote host's (usually a server) version
3996 string. Affected file lib/silcclient/silcapi.h
3998 * Added the KE protocol context to Key Agreement context
3999 in client library so that we can abort the SKE if it
4000 is in process when we get timeout. Affected file is
4001 lib/silcclient/client_keyagr.c.
4003 * Do not resolve the client ID forever if it returns in the
4004 first time that such client does not exist. This was done
4005 for example with private message. Affected file is
4006 lib/silcclient/client_prvmsg.c.
4008 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4010 * Do not add regex.h for WIN32. The affected file
4011 includes/silcincludes.h.
4013 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4014 not work yet 100%. It generates the DLL's automatically
4015 when compiling with --with-win32 under cygwin.
4017 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * lib/contrib/regex.c is not compiled on WIN32.
4021 * Added silc_net_get_socket_opt function to the
4022 lib/silcutil/silcnet.h.
4024 * Added includes/silcwin32.h for WIN32 specific includes
4027 * Do not use ptime structure or any of the posix process
4028 functions on WIN32 in lib/silccrypt/silrng.c.
4030 * Added silc_gettimeofday to provide generic function
4031 for struct timeval on all platforms. Added the function
4032 to lib/silcutil/silcutil.h.
4034 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4036 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4037 library as they clearly belong there. As a plus side we
4038 can make the actual socket connection routines platform
4041 Added also new generic function silc_socket_read and
4042 silc_socket_write (that used to be silc_packet_[read/write].
4043 The implementation of these are platform specific.
4045 * Added WIN32 specific routines of silc_socket_[read/write]
4046 to lib/silcutil/win32/silcwin32sockconn.c.
4048 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4050 * Added preliminary support for native WIN32 compilation under
4051 cygwin (using the -mno-cygwin option for GCC) to the
4052 ./configure.in.pre. The --with-win32 now prepares the
4053 compilation for native WIN32.
4055 * Rewrote the SILC Scheduler interface in the file
4056 lib/silcutil/silcschedule.h. The scheduler is now context
4057 based and does not have anymore any global static scheduler.
4058 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4059 and created lib/silcutil/win32 directory for WIN32 based
4062 * Added Unix specific network routines to the
4063 lib/silcutil/unix/silcunixnet.c and the old
4064 lib/silcutil/silcnet.c includes now only generic routines.
4066 Added WIN32 specific network routines to the
4067 lib/silcutil/win32/silcwin32net.c.
4069 * Added Unix specific utility functions from the
4070 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4072 * Added WIN32 SILC Scheduler to the file
4073 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4076 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * Do not handle JOIN notify in the server if the target client
4079 is not registered (idata->registered == FALSE). The affected
4080 file is silcd/packet_receive.c.
4082 * Update the nickrec->founder in event_cumode in the Irssi SILC
4083 client. Affected file irssi/src/silc/core/silc-channels.c.
4085 * Fixed the CUMODE_CHANGE notify handling in the server when
4086 server and router are announcing their clients on channels.
4087 Now the mode changes are saved and notified correctly. The
4088 affected file is /silcd/packet_receive.c.
4090 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4091 They really did not replace the cache entry in the ID Cache.
4092 Now they do that. Affected file silcd/idlist.c.
4094 * Fixed the KICK notify handling in the Irssi SILC client to
4095 update the channel records so that the kicked client does not
4096 appear to be on the channel. The affected file is
4097 irssi/src/silc/core/silc-channels.c.
4099 * Always update the conn->current_channel when executing command
4100 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4102 * Fixed the KILL notify handling in Irssi SILC client to remove
4103 the killed client on all channels.
4105 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4107 * Fixed the silc_parse_command_line to remove extra spaces
4108 from the start and end of the arguments. Affected file is
4109 lib/silcutil/silcutil.c.
4111 * Cancel and free any active protocol in the function
4112 silc_server_close_connection. Affected file silcd/server.c.
4114 * Cancel and free any active protocol in the function
4115 silc_client_close_connction. Affected file is
4116 lib/silcclient/client.c.
4118 * Do not execute the KILL command for clients that are in
4119 history (ie. they are not in the network). Affected file is
4122 * Fixed KILL notify handling, client does not crash anymore.
4123 Affected file irssi/src/silc/core/silc-channels.c.
4125 * Reduced the default packet buffer size from 2048 to 1024 in
4126 lib/silccore/silcpacket.c.
4128 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4129 counter to the SKE context that is incresed when the SKE library
4130 performs async operation outside the library. If the outside
4131 process frees the SKE context and FREED status will be set
4132 and the library will detect after the sync operation that the
4133 libary is freed. The affected files are
4134 lib/silcske/silcske[_status].[ch].
4136 * Resolve the client entry information in the function
4137 silc_client_channel_message to assure that NULL pointer is not
4138 passed as client entry to the application. */
4140 * Fixed the task timeout calculation to assure that there is
4141 never negative timeouts. The affected file is
4142 lib/silcutil/silcschedule.c.
4144 * Fixed the channel user mode notification sending in server.
4145 It was sent point-to-point to the router (or to server by router)
4146 but it needs to be destined to a channel. The routines now
4147 supports sending the channel user mode notifys to the channels
4148 when announcing clients and channels. Affected files are
4149 silcd/server.c and silcd/packet_receive.c.
4151 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4152 It did not actually replace the old channel entry in the cache.
4153 Affected file lib/silcclient/client_notify.c.
4155 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4157 * Fixed a possible crash in silc_packet_send_prepare. It now
4158 assures always that there is enough space in the buffer and
4159 at the tail area of the buffer (for MAC).
4161 Fixed the inbound buffer reallocation in silc_packet_read.
4162 It was old code and did not handle the reallocation correctly.
4165 The affected file is lib/silccore/silcpacket.c.
4167 * Fixed buffer overflow in silc_parse_nickname in the file
4168 lib/silcutil/silcutil.c.
4170 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * make install generates new server keys only if there is not
4175 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4177 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4178 Added check that if the NOREPLY is set then we will not send
4179 the away message. This avoids infinite loop of away messages
4180 if both clients are away. The affected file is
4181 lib/silcclient/client_prvmsg.c.
4183 * Fixed client crash if /NICK was given without arguments.
4184 Affected file lib/silcclient/command.c.
4186 * Server does not send the invite list in INVITE command back
4187 to the client if the list was not altered. Added this notion
4188 to the protocol spec as well. Affected file silcd/command.c.
4190 Fixed possible crash in INVITE command by checking the
4191 value of silc_server_get_client_route command.
4193 * Fixed the INVITE notify type handling. The arguments are now
4194 taken in correct order and client does not crash. The affected
4195 file is irssi/src/silc/core/silc-channels.c.
4197 Removed the "Inviting xxx to channel" message from the
4198 client library away and let the application handle it.
4199 Affected file lib/silcclient/command.c. Added that message
4200 to Irssi SILC client's message formats.
4202 * Fixed CMODE command crash in client. It now checks the
4203 amount of arguments correctly and does not crash. The affected
4204 file is lib/silcclient/command.c.
4206 * Do not create new channel automatically in silc_channels_join
4207 but check whether the channel by that name already exists.
4208 Affected file irssi/silc/core/silc-channels.c.
4210 * Do not send the SERVER_SIGNOFF to router if the disconnected
4211 entity was the router. Affected file silcd/server.c.
4213 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4214 SILC client as it was missing from there.
4216 Added the handling of the KICK notify to the Irssi SILC client
4217 as it was missing. Added "you have been kicked" message to
4218 Irssi SILC client's message modules formats.
4220 Added the handing of the KILL notify to the Irssi SILC client
4221 as it was missing. Added the kill message module formats
4224 The affected file is irssi/src/silc/core/silc-channels.c.
4226 * The router did not save the channel mode the server announced.
4227 Affected file silcd/packet_receive.c.
4229 * Fixed a possible crash in INFO command in server. If the
4230 server did not provide the server info it crashed. Affected
4231 file silcd/command.c.
4233 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Fixed the GETKEY command in the server to check also the
4236 global list. Otherwise the GETKEY would not work correctly
4237 in normal SILC server. Affected file silcd/command.c.
4239 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Fixed GETKEY crash, it crashed if the command did not succseed.
4243 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4245 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4246 is now real and not just an macro interface to GMP.
4248 Removed the entire GMP from the source tree and imported new
4249 NSS MPI library instead. Reason for removing GMP is that it is
4250 extremely large and compiles extremely slow. The NSS MPI
4251 is only a few files and compiles in less than 10 seconds.
4252 The speed is also about the same as GMP. The MPI is imported
4253 to lib/silcmath/mpi.
4255 If the system has GMP installed we will still use the GMP.
4256 If it is not then the NSS MPI will be compiled.
4258 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Merged a long nickname (127 characters long) crash bugfix from
4261 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4263 * Merged a freed memory reference bugfix from Irssi CVS tree.
4264 Affected file irssi/src/core/commands.c.
4266 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Added the server's public key sving and verification to the
4269 server when performing the SKE. This was missing and the
4270 remote server's (or router's) public key was accepted without
4271 checking whether we have it previously or trust it at all.
4272 Affected file silcd/protocol.c.
4274 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Check in the silc_server_timeout_remote if protocol is active
4277 and make sure that the protocol's final callback is called so
4278 that all memory if freed. Affected file silcd/server.c.
4280 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * silc_server_whois_send_reply crashed the server if the nickname
4283 was 127 characters long. Affected file silcd/command.c.
4285 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Added sanity check to the silc_server_new_client. If the hostname
4288 is provided inside username then check that the provided hostname
4289 really is the same as the resolved one. If the hostname was not
4290 resolved then check it from the public key. Affected file is
4291 silcd/packet_receive.c.
4293 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4294 if the server disconnected us and the connection is not valid
4295 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4297 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4298 the library to the lib/silcutil/silcutil.[ch].
4300 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Close log file after open. Affected file
4303 lib/silcutil/silclog.c.
4305 * Check whether sock == NULL in silc_client_send_packet and return
4306 if it is. Affected file lib/silcclient/silcclient.c.
4308 * Check rec->entry == NULL in the Irssi SILC Client before
4309 sending the channel message. Affecte file is
4310 irssi/src/silc/core/silc-servers.c.
4312 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4314 * Merged a splitted window bugfix from Irssi CVS tree. The
4315 affected file is irssi/src/fe-text/textbuffer-view.c.
4317 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4318 It did not print nickname.
4320 * Improved the distributions system a bit.
4322 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4324 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4325 irssi/src/fe-text/gui-window.c.
4327 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4328 to in-active server. The affected file is
4329 irssi/src/silc/core/client_ops.c.
4331 * Resolve the client in USERS command reply if the entry does
4332 not have username resolved. The affected file is
4333 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4334 command to WHOIS command to really resolve stuff. The USERS
4335 is not used any more in any critical section so WHOIS can
4336 be used even though it might be slower than IDENTIFY.
4338 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4341 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Changed the protocol API a bit more consistent in the
4344 lib/silccore/silcprotocol.[ch].
4346 * Changed the following headers to ROBODoc format:
4348 lib/silccore/silcpayload.h
4349 lib/silccore/silcprotocol.h
4350 lib/silccore/silcsockconn.h
4352 All core library headers are now formatted.
4354 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Fixed a bug in Irssi SILC client; do not show that you are
4357 server/router operator if you really are not. Affected file is
4358 irssi/src/silc/core/client_ops.c.
4360 * Renamed silc_command_free_payload to silc_command_payload_free.
4361 Affected file lib/silccore/silccommand.h
4363 * Added silcmath.h to include the prototoypes of various routines
4364 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4367 * Changed the following headers to ROBODoc format:
4369 lib/silccore/silcchannel.h
4370 lib/silccore/silccommand.h
4371 lib/silccore/silcid.h
4372 lib/silccore/silcidcache.h
4373 lib/silccore/silcmode.h
4374 lib/silccore/silcnotify.h
4375 lib/silccore/silcpacket.h
4376 lib/silcmath/silcmath.h
4378 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4380 * Added checking to the server code not to start the server if
4381 ciphers and stuff are not configured properly. Affected files
4382 silcd/serverconfig.[h] and silcd/server.c.
4384 * Changed the layout of the header files of the public interfaces
4385 in the SILC libraries. The new layout supports ROBODoc
4386 documentation tool (and some others) so that it is easy to create
4387 a library reference manual. All the other headers and source
4388 code must still follow the CodingStyle document. Also source
4389 code must not include these ROBODoc stuffs, only the headers.
4390 Furthermore, all public interface headers must now be named
4391 by using `silc' prefix, example: silcapi.h, silccipher.h.
4392 Some files were renamed due to this. All the other headers
4393 must not be used as public interfaces. I will update the
4394 CodingStyle document later. Changed following headers, so far:
4396 lib/silcclient/silcapi.h
4397 lib/silccore/silcauth.h
4398 lib/silccore/silcprivate.h
4399 lib/silccrypt/silcdh.h
4401 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Removed silc_client_packet_send_flush from the client library
4406 as it is not needed. Affected file lib/silcclient/client.[ch].
4408 * Added printing of message of unresolved authentication method
4409 to the Irssi SILC client. Added it to the module formats.
4410 Removed the same message from the client library.
4412 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4414 * Added new distribution feature, DISTLABEL. Every distribution
4415 can define own preprocessor label that can be used in the
4416 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4417 file distributions, acconfig.h.pre and prepare.
4419 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4421 * Added Makefile.defines_int to include the actual definitions
4422 for Makefile.defines.in. Tested the new distribution system,
4423 created distributions and tested installation.
4425 * Added AWAY message printing to the Irssi SILC client. Added
4426 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4428 * Added SCONNECT command to call the SILC's CONNECT command.
4429 Cannot use CONNECT directly since Irssi uses that internally.
4430 Affected file irssi/src/silc/core/silc-servers.c.
4432 Added ACTION local command. It is same as ME command but takes
4433 the channel as mandatory argument.
4435 Rewrote some of the Irssi's help files to suite for SILC
4438 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Added Makefile.defines[.in] that should for now on be included
4441 in all Makefile.am file in the source tree. That file includes
4442 all common compilation definitions for SILC source tree.
4444 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4446 * Minor changes to the ./prepare script to change the package
4447 name according the distribution name to the configure.in.
4449 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Created new distribution system. Added file `distributions'
4452 that defines all the distributions that can be created out of
4453 the SILC source tree. The ./prepare script now reads that
4454 file to determine how to prepare the distributions. The
4455 first argument to the ./prepare is the name of the distribution
4456 and second is the version of the distribution. If given
4457 without arguments it creates the default (toolkit) distribution
4458 with the default version (defined in ./prepare).
4460 All Makefile.am files that are subject to the distributions
4461 are now named as Makefile.am.pre. These are ./Makefile.am
4462 and lib/Makefile.am. Others may be changed later.
4464 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added invite list, ban list, some key management and connection
4467 error message printing to module formats in the Irssi SILC client.
4469 * Added new silc_client_set_away_message to set the away message
4470 that is back to the person who sent private message. The
4471 affected file lib/silcclient/silcapi.h and the
4472 lib/silcclient/client_prvmsg.c.
4474 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * Fixed the private message sending in the Irssi SILC client,
4477 added local command KEY to the Irssi SILC client.
4479 Added key management and key agreement message formats to the
4480 irssi/src/fe-common/silc/module-formats.[ch].
4482 Added USERS (alias WHO) printing, server/router operator
4483 indication and LIST command printing to the module formats.
4485 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4487 * Fixed channel joining notify handling, cumode notify handling
4488 from Irssi SILC client.
4490 * Added SILC specific module-formats to the Irssi SILC client so
4491 that SILC specific message hilighting, colors etc is possible.
4492 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4494 Added channel mode, channel user mode, actions, notices,
4495 whois and whowas printing to the the module-formats.c.
4497 * Fixed a bug in channel deletion in the server. The channel
4498 is not left to the cache even if the channel founder auth mode
4499 is set when there are no users anymore on the channel. Affected
4500 file silcd/server.c.
4502 * The silc_net_localhost now resolves the entire hostname including
4503 the domain name. Affected file lib/silcutil/silcnet.c.
4505 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4507 * Changed the ask_passphrase client operation to be ascynchronous.
4508 It has now a completion callback and a context that the
4509 application must call after it has got the passphrase from
4510 the user. Affected files lib/silcclient/silcapi.h,
4511 lib/silcclient/protocol.c, lib/silcclient/command.c and
4514 Added SilcAskPassphrase callback that the application calls
4515 to deliver the passphrase to the library.
4517 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4518 The public key verification and especially a certificate
4519 verification is asynchronous procedure.
4521 Added new SILC_SKE_STATUS_PENDING status to indicate the
4522 request is pending and a callback will be called to finalize
4525 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4526 indicate that remote end did not send its public key (or
4527 certificate), even though we require it. Added check for this
4528 condition in the SKE. This was a security bug, now fixed.
4530 Defined new SilcSKEVerifyCbCompletion callback that is called
4531 when the verification process is completed.
4533 The affected files lib/silcske/silcske_status.h and
4534 lib/silcske/silcske.[ch].
4536 * Changed the verify_public_key client operation to be async
4537 as well. Defined SilcVerifyPublicKey callback that is used to
4538 indicate the success of the public key verification process.
4540 Changed the server and client to use the new async client
4543 * Changed the Irssi SILC client's internal scheduler to be called
4544 twice as many times as it used to be. As a result the client
4545 should be a bit faster now. Affected file is
4546 irssi/src/silc/core/silc-core.c.
4548 * Added support to Irssi SILC client of asynchronous public key
4549 verification and passphrase inquiry. Affected file is
4550 irssi/src/silc/core/silc-core.c.
4552 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Do not say "You have left channel %s" in client library.
4555 Moved it to the application. Affected files are
4556 lib/silcclient/command.c and silc/client_ops.c.
4558 * Fixed silc_client_get_clients. Command context was not
4559 duplicated and was freed memory in the callback. Affected
4560 file lib/silcclient/idlist.c.
4562 * Do not say "you are now talking..." on JOIN command in the
4563 client library. The appliation must handle it.
4565 * Do not say ".. changed topic to" in command reply in the
4566 client libary. The application must handle it.
4568 * Fixed TOPIC command sending in the client library.
4570 * Fixed a memory leak in silc_client_command_free in the file
4571 lib/silcclient/command.c.
4573 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Imported a modified version of Irssi client to the source tree.
4576 The Irssi will be used to create a new client called
4577 Irssi SILC. Imported to irssi/.
4579 Added silc_core_init_finish function to the Irssi. Affected
4580 file irssi/configure.in.
4582 A lot changes in the Makefile.ams around the irssi tree.
4584 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4586 * Do not rehash if the new size is same as the old size of the
4587 hash table, in the silc_hash_table_rehash*. The affected file
4588 lib/silcutil/silchashtable.c.
4590 * Replaced hash_table_del_by_context calls from the server
4591 (when channel->user_list and client->channels) to the
4592 hash_table_del as it is sufficient and faster.
4594 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Added silc_hash_table_list, silc_hash_table_get and the
4597 SilcHashTableList structure to provide an alternative way to
4598 traverse the hash table. The affected files are
4599 lib/silcutil/silchashtable.[ch].
4601 * Changed the server's idlist routines to use the hash table
4602 routines to optimize the code.
4604 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Replaced the client entry's `channel' list and channel entry's
4607 `user_list' list to hash tables for optimized lookup. Changed
4608 the code to use the hash table interface around the code.
4609 Affected file lib/silcd/idlist.[ch].
4611 * Added `auto_rehash' boolean argument to the function
4612 silc_hash_table_alloc to indicate whether the hash table should
4613 auto-rehash when it thinks is appropriate time. It will
4614 increase the hash table size if the there is twice as much
4615 entries in the table than the size of the table, and will
4616 decrease the size if there are twice as less entries than
4617 the size of the table.
4619 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4623 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * silc_idcache_purge_by_context deletes the entry now by context
4626 as it is supposed to do. Affected file lib/silccore/idcache.c.
4628 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4629 client is not anymore valid (WHOWAS givens the info) and not
4630 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4632 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4634 * Removed the `data' and `data_len' arguments from the ID Cache
4635 interfaces and added `name' argument. ID Cache does not handle
4636 anymore the binary data only a names associated with given ID.
4638 * When hashing a Client ID with silc_hash_id the entire ID is
4639 not hashed anymore, instead only the hash of the Client ID is
4640 hashed. This way we can access the Client ID from the cache
4641 with Client ID but with the hash of the ID (which is a hash of
4642 the nickname) as well without any difference in performance.
4644 Added also silc_idcache_find_by_id_one_ext to do one on one
4645 searching when we have the actual ID. Added also function
4646 silc_hash_client_id_compare. The affected files are
4647 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4649 * When hashing the name associated with a ID it is always done
4650 in lowercase. This way we can access the cache without worrying
4651 about case-sensitivity, even though, for example nicknames are
4654 * Fixed a bug in server with channel message sending. It put
4655 wrong ID type as destination ID. The affected file
4656 silcd/packet_send.c.
4658 * silc_idcache_del_by_context now deletes from all hash tables
4659 by context. Affected file lib/silccore/idcache.c.
4661 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Changed the client library to use the new ID Cache interface.
4664 Changes around the source tree.
4666 * Added silc_hash_table_rehash_ext to rehash with specific
4667 hash function. Affected file lib/silcutil/silchashtable.[ch].
4669 * Added silc_hash_string_compare to compare two strings in the
4670 hash table. Affected file lib/silcutil/silcutil.[ch].
4672 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Added new function silc_idcache_del_by_context into the
4675 lib/silccore/idcache.[ch].
4677 * Changed the server's ID list routines to use the new ID Cache
4678 interface. Changes around the source tree.
4680 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Added silc_hash_table_del[_by_context]_ext functions in to the
4683 lib/silcutil/silchashtable.[ch].
4685 Removed silc_hash_table_find_all* routines and added new
4686 silc_hash_table_find_foreach to replace them.
4688 Added silc_hash_table_replace_ext function as extended
4689 replacing function. Separated the simple hash table interface
4690 from the extended hash table interface in the file
4691 lib/silcutil/silchashtable.h.
4693 * Fixed minor bugs and changed it to use some of the new
4694 hash table functions in lib/silccore/idcache.c
4696 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4698 * Added new function silc_hash_table_find_all to return all keys
4699 in the hash table by the specified key. As the hash table is
4700 collision resistant it also makes it possible to have several
4701 duplicate keys in the hash table. This function may be used to
4702 find all of the keys from the hash.
4704 Added user_context arguments to the SilcHashFunction,
4705 SilcHashCompare and SilcHashDestructor to deliver user specified
4708 Added new fuctions silc_hash_table_find[_all]_ext to do
4709 extended lookup with specified hash and compare functions and
4710 specified user contexts.
4712 Added new function silc_hash_table_add_ext to add the key
4713 with specified hash function and user context.
4715 Added new function silc_hash_table_foreach to traverse all
4716 entrys in the hash table. Added SilcHashForeach callback
4719 Added new function silc_hash_table_del_by_context to delete
4720 the entry only if the context associated with the key matches.
4722 Affected files are lib/silcutil/silchashtable.[ch].
4724 * Removed silc_hash_[server/client/channel]_id and added just
4725 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4726 silc_hash_id_compare to compare two ID's using as the hash table
4727 comparison function. Added also silc_hash_data to hash
4728 binary data and silc_hash_data_compare to compare it.
4730 * Removed silc_idlist_find_client_by_hash as it is not needed
4731 anymore. Affected file silcd/idlist.[ch].
4733 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4734 to use internally the SilcHashTable. The new ID Cache is a lot
4735 faster than the old one. Some of the ID Cache interface was also
4736 rewritten and obsolete and stupid functions were removed.
4738 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Added entry_count field to the SilcHashTable to keep the number
4741 of the entries in the table. Implemented the function
4742 silc_hash_table_rehash. Added new function
4743 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4745 Fixed a minor bug in silc_hash_table_free.
4747 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4748 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4749 into the lib/silcutil/silcutil.[ch].
4751 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Implemented a collision resistant hash table into the
4754 lib/silcutil/silchashtable[ch]. See the header and the source
4755 for the SilcHashTable API.
4757 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Merged dotconf version 1.0.2 into lib/dotconf.
4761 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Do not compile anything in lib/silcsim/* if the SIM support
4764 is not enabled. The tree should now compile without problems
4767 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Compiled the SILC under cygwin. Compiled and tested briefly
4770 without problems. More tests needed. The SIMs didn't compile
4773 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4775 * Fixed possible crash in silc_get_username in the
4776 lib/silcutil/silcutil.c.
4778 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Fixed a va_arg in silc/client_ops.c.
4782 * Oops, RC5 routines were named AES and caused some problems
4783 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4785 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Added new SilcIDIP structure into the lib/silccore/id.h and
4788 replaced the old `ip' fields from all SILC ID's to that type.
4789 This is a step towards IPv6 support.
4791 The silc_id_get_len takes now the ID as an extra argument.
4792 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4793 both IPv4 and IPv6 based ID's.
4795 The affected files are lib/silccore/id.[ch] and other files
4796 around the tree using these routines.
4798 * Removed the ID length arguments in server from various
4799 silc_server_send_notify_* routines -> they are not needed
4802 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Fixed memory leak in silc_encode_pem_file in the file
4805 lib/silcutil/silcutil.c.
4807 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Check minor version as well in the SKE. Affected files are
4810 silcd/protocol.c and lib/silcclient/protocol.c.
4812 * Added --identifier option to the server so that an identifier
4813 can be when creating the public key for the server. Affected
4814 file is silcd/silcd.c.
4816 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4817 lib/silccrypt/silcpkcs.c.
4819 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Register default ciphers and stuff when using -C option with
4822 the server. Affected file sildc/silcd.c.
4824 * Put back the servers public key filename format, it is better
4825 than the new one. For now, the client keys are saved with the
4826 new filename format. The affected file silc/client_ops.c.
4828 * Implemented the Cipher API for the rest of the ciphers that
4829 did not implement it or implemented it the wrong way.
4831 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Register default ciphers and stuff when using the -S option
4834 in the client. Affected file silc/silc.c. Same also when
4835 creating new key pair with -C option.
4837 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Fixed the silc_verify_public_key client operation function to
4840 save the public keys differently. The fingerprint is now
4841 used as filename and not the hostname. This way also the
4842 client keys are saved uniquely and not with hostnames. The
4843 affected file is silc/client_ops.c.
4845 * Trimmed the silc_hash_fingerprint function to remove extra
4846 whitespaces from the end of the fingerprint. The affected
4847 file is lib/silccrypt/silchash.c.
4851 * Added silc_cipher_register_default function to register all
4852 default ciphers. It can be used when configuration files
4853 does not exist and the application does not want any specific
4854 ciphers in any specific order.
4856 The SilcDList is now used as silc_cipher_list dynamically
4857 allocated cipher list. Removed the static list all together
4858 and now all ciphers must be allocated to the dynamic list.
4859 The silc_cipher_alloc routine was changed to check only the
4862 All silc_cipher_* routines that used to return int returns
4865 The affected files lib/silccrypt/silccrypt.[ch].
4867 * The same thing was done to silc_hash_* as for silc_cipher_*
4868 routines. Affected files lib/silccrypt/silchash.[ch].
4870 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4871 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4872 Added also silc_pkcs_[un]register[_default] functions.
4873 Removed the data_context from the PKCS API.
4875 * Added silc_hmac_register_default function to register default
4876 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4877 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4878 to unregister all hmacs at once.
4880 * Register the default ciphers, hash functions, PKCSs and HMACs
4881 if client's configuration file does not exist. The affected
4884 * The client did not load the hash functions from the SIM
4885 modules at all. Added support for this. Affected file is
4886 silc/clientconfig.c.
4888 * When decoding public key with silc_pkcs_public_key_decode, check
4889 the supported algorithm only if PKCS are registered. Affected
4890 file lib/silccrypt/silcpkcs.c. The same was done with the
4891 silc_pkcs_private_key_decode.
4893 * Fixed the SILC List routines to keep the list always in order.
4894 It used to change the list's order when traversing the list but
4895 not it preserves the order. Affected file lib/trq/silclist.h.
4897 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added the client library to use the SilcSocketConnection's
4900 reference counter (by silc_socket_dup) to prevent the bug that
4901 the socket object may be freed underneath async operation.
4903 * The name resolv library checking fixes in the configure.in.pre.
4906 * Created new version of the protocol drafts for future
4907 development. The -03 drafts are the ones that will be changed
4908 in the trunk now and the -02 will remain as they are.
4910 * Send list of CUMODE notifys to the router when announcing
4911 the channel users to the router. Affected file silcd/server.c.
4912 If the router receiving channel founder CUMODE for a channel
4913 that already has channel founder it will send CUMODE notify
4914 to the sender to remove the channel founder rights from the
4915 announced client. Affected file silcd/packet_receive.c.
4917 * The CUMODE notify may now use Server ID as well as the entity
4918 who changes the mode. Updated protocool specs.
4920 * Updated INSTALL and README files.
4922 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * New web pages in the http://silc.pspt.fi. The pages was
4929 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4931 * Implemented the [DenyConnectin] config section in the server.
4932 Added silc_server_config_denied_conn to check whether incoming
4933 connection is denied. Affected file silcd/serverconfig.[ch].
4935 * Do not check the ports when checking the incoming configuration
4936 data if the port is 0, meaning any. Affected file is
4937 silcd/serverconfig.c.
4939 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * Fixed buffer overflow in silc_string_compare in the file
4942 lib/silcutil/silcutil.c.
4944 * Fixed double free in silc_server_command_leave in the file
4947 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed the version checking in the server. Affected file is
4952 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Fixed the configuration data fetching when accepting new
4955 connections in the server. Affected file silcd/server.c.
4957 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Added `sender_entry' argument to the function
4960 silc_server_packet_relay_to_channel so that we can check
4961 whether some destination actually belongs to the same route
4962 the sender belongs (ie, we must not resend the packet to the
4963 sender). Affected file silcd/packet_send.[ch].
4965 * Added `servername' field to the SilcClientEntry in the server
4966 to hold the name of the server where client is from. Affected
4967 file is silcd/idlist.h.
4969 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Moved the channel message encrypting in the router betwen
4972 router connections from silc_server_channel_message to the
4973 silc_server_packet_relay_to_channel since we want to check
4974 whether we have anybody channel before encrypting anything.
4975 Affected files silcd/packet_[receive/send].c.
4977 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Fixed the [AdminConnection] server config section to support
4980 multiple entries. Affected file silcd/serverconfig.c.
4982 * Added support into the server to check the validity of the
4983 incoming connection before executing any KE or authentication
4986 * The connection configuration is now saved to the KE and
4987 connection auth protocol contexts and not fetched anymore in
4988 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4990 * The local hosts listenning address and port is also resolved
4991 now when starting the server. We want to have the socket object
4992 to include the real address and port for the listener. Added
4993 new function silc_net_check_local_by_sock into the files
4994 lib/silcutil/silcnet.[ch].
4996 * Fixed a broadcast bug in server -> do not broadcast if we
4999 * Fixed a routing bug. Do not route broadcast packets ever.
5000 Broadcast packets must be processed always and not routed since
5001 they may be destined to some other host than yourself and thus
5002 would get routed without no good reason. Affected file is
5005 * Added function silc_server_config_is_primary_route to check
5006 whether primary router connection has been configured (a router
5007 configuration that we are initiating). If there is not, we
5008 will assume that there is only two routers in the SILC network
5009 and we will use the incoming router connection as our primary
5010 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5012 * Changed the order of the broadcasting. Broadcast _after_ the
5013 packet has been processed not before. Affected file is
5016 * Fixed a [ClientConnection] parsing bug. The port was never
5017 parsed correctly thus resulting to port 0. Affected file
5018 silcd/serverconfig.c.
5020 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5021 argument and did not set the broadcast packet flag. Affected
5022 file silcd/packet_send.c. Fixed same bug in the function
5023 silc_server_send_notify as well.
5025 * If we receive NEW_ID packet for our own ID in the server, ignore
5028 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5032 * Removed the nickname from the Private Message Payload.
5033 Updated the code and the protocol specs.
5035 * Updated protocol specs for submitting to the IETF.
5037 * Tweaked the Random Number Generator a bit. Affected file
5038 lib/silccrypt/silcrng.c. Exported a new function
5039 silc_rng_[global]_add_noise which can be used to add more
5042 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Do not parse packets with different timeout when protocol
5045 is active -> may cause problem with rekey. Affected file
5048 * When server receives signoff notify it must not create
5049 new channel key if the client is on any channels since the
5050 sender of the signoff notify will create it.
5052 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5054 * Added printing of error messages during SKE protocol from the
5055 failure packet sent by server during SKE. Affected file
5058 * Removed the client's failure_callback handling with timeout
5059 and handle it immediately when received.
5061 * The SKE library returned wrong type in SUCCESS and FAILURE
5062 packets. They must be 32 bit MSB not 16 bit MSB.
5064 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Ok, rewrote the logic of the re-key and now it seems to work.
5067 I tested it on high traffic with frequent re-keys without
5068 problems. Added hmac_receive (and renamed hmac to hmac_send)
5069 in SilcClientConnection in lib/silcclient/client.h and
5070 in SilcIDListData in silcd/idlist.h. Also, removed the
5071 SilcPacketParserContext's cipher and hmac fields as they are
5072 not needed anymore and actually caused some problems when
5073 the ciphers and hmac's changed underneath the packet parser.
5075 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * If re-key protocol is active then process the incoming packets
5078 synchronously since we must assure that icoming packets encrypted
5079 with the old key is processed before the new keys is set to
5080 use. This is true other packets than for REKEY packets.
5081 Affected file silcd/server.c. The same was done to client library
5082 as well, affected file lib/silcclient/client.c.
5084 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Fixed bug in client and server to accept the force send if
5087 the packet is send from silc_[server/client]_packet_process
5088 function. Otherwise the packets are never delivered, oops.
5090 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Disable force sending of packets when REKEY protocol is active.
5093 We must assure that no packet is sent directly when rekey is
5094 performed. All packets must be sent through packet queue.
5095 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5096 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5097 function is silc_[server/client]_packet_send_real to check
5100 * Replaced the SIM paths from example config files to
5101 /usr/local/modules. Also, make install creates now
5102 /usr/local/silc/logs directory to hold all the SILC server
5105 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Made the configure.in.pre work on Solaris. Patch by salo.
5109 * Made all ciphers compatible with non-x86 machines. Defined
5110 CBC mode macros into lib/silccrypt/ciphers_def.h.
5112 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5114 * Fixed the make install.
5116 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * When MAC computation fails the silc_packet_decrypt returned 0
5119 even though it was supposed to return -1. Fixed this. The
5120 affected file is lib/silccore/silcpacket.c.
5122 * Do not replace the config files in /etc/silc (in make install)
5123 if they already exist. Affected file ./Makefile.am.
5125 * Do not send re-key packets immediately but through packet queue.
5126 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5128 * Changed silc_net_check_host_by_sock to return FALSE if the
5129 IP/DNS could not be resolved. Though, it returns the IP address
5130 now even if it could not resolve it (but returns also FALSE).
5131 Affected file lib/silcutil/silcnet.[ch].
5133 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added silc_pkcs_decode_identifier to decode the public key's
5136 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5137 Added also silc_pkcs_free_identifier. Added also new context
5138 SilcPublicKeyIdentifier.
5140 * Added -S option to the silc client. It is used to dump the
5141 contents of the specified public key file.
5143 * Changed the PKCS api to return the public key length when
5144 setting the public key.
5146 * Fixed a fatal bug in the public and private key file loading.
5147 Affected file lib/silccrypt/silcpkcs.c.
5149 * Execute the packet parsing for client with zero (0) timeout
5150 if the protocol is active. Affected file silcd/server.c.
5152 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Made the key generation options to the silcd program. Added
5155 -C option, equivalent to client's option.
5157 * Added new [ServerKeys] config section to the server. It
5158 configures the server's public and private key.
5160 * Defined generic Public Key Payload into the protocol
5161 specification to send specific type of public keys and
5164 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5165 public key or certificate.
5167 * Implemented the GETKEY command to the server and to the
5168 client library and on user interface.
5170 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Made preliminary `make install' work.
5174 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5176 * Added SilcServerRekey context into silcd/idlist.h.
5178 * Added the PFS support as defined in the specification to the
5179 SKE protocol. Affected files lib/silcske/*.c.
5181 * Added `ske_group' field to the SilcServerRekey context to hold
5182 the number of the SKE group that is used with PFS in re-key.
5183 Affected file silcd/idlist.h.
5185 * Added PFS re-key support to the server. Affected file is
5188 * Added silc_protocol_cancel to cancel execution of the next
5189 state of the protocol. Affected file is
5190 lib/silccore/silcprotocol.[ch].
5192 * Added the re-key support with and without PFS to the client
5193 library. Re-key is performed once in an hour, by default.
5195 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5196 Added silc_client_rekey_callback and silc_client_rekey_final.
5197 Affected files are lib/silcclient/protocol.[ch] and
5198 lib/silcclient/client.[ch].
5200 * Removed the `hmac_key' and `hmac_key_len' fields from the
5201 SilcClientConnection structure; not needed. Affected file is
5202 lib/silcclient/client.h.
5206 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5208 * Do not ask whether user wants to use the negotiated private key
5209 for private messages, just use it. Affected file is
5210 silc/local_command.c.
5212 * Added `send_enc_key' and `enc_key_len' fields to the
5213 SilcIDListData structure since they are needed in the re-key
5214 phase. Affected file is silcd/idlist.[ch].
5216 * Implemented the simple re-key protocol into the server.
5217 Affected files silcd/server.c and silcd/protocol.[ch]. The
5218 re-key will be performed once in an hour, by default.
5220 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5221 Added silc_server_rekey, silc_server_rekey_callback and
5222 silc_server_rekey_final.
5224 * Removed Tunneled flag from the protocol. Updated the code
5225 and the specifications.
5227 * Adde `pfs' field to the SilcIDListData to indicate whether
5228 the PFS is to be performed in the re-key. Affected file is
5231 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5234 int64 of at least the xintXX size. If void * is less that 4
5235 bytes uint32 * will be used. Defined bool as boolean.
5237 * Changed _ALL_ unsigned long and unsigned int to uint32,
5238 unsgined short to uint16 in the source tree.
5240 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5241 not handle clients that has entry->data.registered == FALSE.
5242 They are not in the network anymore. Affected file is
5245 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Implemented the sending of the SERVER_SIGNOFF notify in the
5248 server. Affected file is silcd/server.c.
5250 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5251 Added also silc_notify_payload_encode_args into the
5252 lib/silccore/silcnotify.[ch].
5254 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5255 Affected file silcd/packet_receive.c.
5257 * Implemented the SERVER_SIGNOFF notify handling in the client
5258 library. Affected file lib/silcclient/client_notify.c. Also,
5259 implemnted the printing of the SERVER_SIGNOFF info to the
5260 application. Affected file silc/client_ops.c.
5262 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5263 if the deleting was successful. Affected file silcd/idlist.[ch].
5265 * Added support for public key authentication in the connection
5266 authentication protocol in the client library. Affected file
5267 lib/silcclient/protocol.c.
5269 * Changed the server's silc_idlist_get_clients_by_* interface
5270 to support already allocated array so that new entries may be
5271 added to pre-allocated array. Affected file silcd/idlist.[ch].
5272 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5273 and command replies.
5275 * All command reply functions in the server now calls the
5276 pending command callback even if error occured. This way the
5277 error will be delivered to the client as well. Affected files
5278 silcd/command.c and silcd/command_reply.c.
5280 * Fixed INFO command to return local server's info if no server
5281 was provided. Affected file lib/silcclient/command.c.
5283 * Removed RESTART command for good. Updated the code and the
5286 * Rewrote parts of the task system. It is a bit simpler now.
5287 Removed unsued task priorities. The affected files are
5288 lib/silcutil/silctask.[ch].
5290 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Moved the USERS printing from the library to the application.
5293 Affected files lib/silcclient/command.c and silc/client_ops.c.
5295 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Added channel key re-key support. The re-key is perfomed
5300 only by the router and is done once in an hour. Added `rekey'
5301 field to the SilcChannelEntry in the server. Affected files
5302 silcd/server.c and silcd/idlist.h.
5304 * Added silc_task_unregister_by_context into the file
5305 lib/silcutil/silctask.[ch].
5307 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Added SILC_UMODE_GONE mode to indicate when the client is not
5310 present in the SILC network. Added also support to the local
5311 command AWAY that will set this mode. Added support of showing
5312 "xxx is gone" in WHOIS command. The USERS command shows the
5313 gone status as well.
5315 * Fixed setting server and router operator privileges in the
5316 server's UMODE command. Affected file silcd/command.c.
5318 * Merged the SKE KE1 and KE2 payloads into one payload. The
5319 new KE payload is equivalent to the old KE2 payload.
5321 Cleaned up the SKE Start Payload parsing. It now uses the
5322 simple buffer unformatting to do the parsing. A lot faster
5325 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5326 to the SKE that is used to indicate whether both of the SKE
5327 parties should perform authentication. By default only the
5328 responder performs authentication. By setting this flag also
5329 the initiator must do authentication. By default it is unset
5330 since in normal SKE case, client to server connection, only
5331 the responder should do authentication. When doing SKE between
5332 two clients both should perform authentication. Updated the
5333 code and the protocol specs.
5335 * A little fix to IDENTIFY command in the server. Search the
5336 client first by hash not nickname. Affected file is
5339 * Fixed the silc_client_close_connection to support closing
5340 the client to client connections wihtout deleting too much
5341 data. Affected file lib/silcclient/client.c.
5343 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5344 are received if protocol used to be active but is not anymore
5345 the application would crash due to NULL pointer dereference.
5346 Affected files silcd/server.c and lib/silcclient/client.c.
5348 * Added `hash' field to the SilcClientConnection to include
5349 the hash function negotiated in the SKE protocol.
5351 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5352 to set the channel founder authentication data. A client can
5353 claim the founder rights later by providing the authentication
5354 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5355 This way the channel founder can regain the channel founder
5356 privileges even it is left the channel. This works only on
5357 local server and the client must be connected to the same
5358 server to be able to regain the founder rights. Updated the
5359 protocol specs accordingly.
5361 Added support to the CMODE command in the client to set the
5362 founder auth data. Read the README to see how to set it.
5364 Added support to the CUMODE command to claim the founder
5365 rights. Read the README to see how to do it.
5367 Added support for the founder authentication to the Channel
5368 Entry in the server. Affected file silcd/idlist.h.
5370 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5371 server's CMODE command. Affected file silcd/command.c.
5373 * Added the following new functions into lib/silccore/silcauth.[ch]:
5374 silc_auth_get_method and silc_auth_get_data.
5376 * The server now saves the remote hosts public key to the
5377 SilcIDListData pointer. Affected file silcd/protocol.c.
5379 * The normal server now does not remove the channel entry from
5380 the cache if the founder authentication data is set. It used
5381 to remove it if the founder was the last one on the channel on
5382 the server and left the channel. The auth data is saved and
5383 if the channel is re-joined later the old entry is used with
5384 the old auth data. Affected files silcd/command_reply.c and
5387 * Removed the `pkcs' field from the SilcIDListData structure
5388 in the server; it is not used. Affected file silcd/idlist.h.
5390 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5392 * Fixed packet processing on slow links. Partial packets were
5393 never re-processed because the incoming data buffer was cleared
5394 by the application. Application must not directly clear the
5395 sock->inbuf, the packet processing routines handle it. Fixed
5396 this in client library and in server.
5398 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Fixed the WHOIS and IDENTIFY send reply function to really
5401 check whether to send list or just one entry. Affected file
5404 * Cleaned up the LEAVE command's channel key distribution. The
5405 affected file silcd/command.c.
5407 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5408 can enforce the channel mode as well. In that case the ID
5409 includes the ID of the server. The code now enforces the
5410 mode change if the router have different mode than the server.
5412 * The notify client operation with CMODE_CHANGE notify can now
5413 return NULL client_entry pointer if the CMODE was not changed
5414 by client. Application must check for this.
5416 * Added <Server ID> argument to INFO command to support server
5417 info fetching by Server ID.
5419 * Added silc_server_announce_get_channel_users to get assembled
5420 packets of channel users of the specified channel. Affected
5421 file silcd/server.[ch].
5423 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5424 was freed underneath the ID Cache.
5426 * Re-announce clients when the server received CHANNEL_CHANGE
5427 notify from the router. Affected file silcd/packet_send.c.
5429 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5432 crashed since it did not handle the fact that there is no cipher
5433 called "3" and didn't check the error condition. Now fixed.
5435 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5436 flag. It can be used to send message requests.
5438 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Implemented the RESTART command in the client.
5442 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5443 notice type messages. Added notice printing to the user
5446 * The channel keys are not re-generated if the channel's mode
5447 is PRIVKEY, ie private key on the channel exists. Affected
5448 files silcd/server.c and silcd/command.c.
5450 * Fixed a little bug in channel message delivery when channel
5451 private keys are set in the server. Affected file is
5452 silcd/packet_send.c.
5454 * Changed the setting on channel->on_channel = TRUE from the
5455 silc_client_save_channel_key to the JOIN command reply. The
5456 key payload is not received if the private channel key is set.
5457 Affected file lib/silcclient/command_reply.c and the
5458 lib/silcclient/client_channel.c.
5460 * When the CMODE_CHANGE notify is sent and the channel private
5461 key mode is removed the channel key must be re-generated in
5462 other cells as well. Added this support for the router in the
5463 silcd/packet_receive.c.
5465 * Added new local command NOTICE to send notice message on
5466 channel. Affected file silc/local_command.[ch].
5468 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Added new local command ME to the client. It is used to send
5471 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5472 some action. Affected file silc/local_command.[ch].
5474 * Changed channel_message and private_message client operations
5475 to deliver the message flags to the application. Added also
5476 the `flags' arguments to the silc_client_send_channel_message
5477 and silc_client_send_private_message functions. Affected file
5480 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Redefined the Private Message Payload to support private message
5483 keys and to support the new private message flags. Updated
5484 the protocol specs. Flags makes it possible to have for example
5485 CTCP style messages.
5487 * Added new type SilcPrivateMessagePayload and defined an API
5488 for it in the lib/silcclient/silcprivate.[ch].
5490 * Tested private message private keys successfully. Tested the
5491 private message key set, unset and list commands with the new
5494 * Redefined the Channel Message Payload to include the channel
5495 message flags (equal with private message flags) to support
5496 for example CTCP style messages.
5498 * Defined some of the message (for channel and private message)
5499 flags. Updated the protocol specs and added the flags to the
5500 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5502 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added SilcKeyAgreementStatus type to the key agreement routines
5505 to indicate the current status and error if one occured.
5506 The status types are defined in the lib/silcclient/silcapi.h.
5508 * Added new local command KEY that is used to set and unset private
5509 keys for channels, set and unset private keys for private messages
5510 with remote clients and to send key agreement requests and
5511 negotiate the key agreement protocol with remote client. The
5512 key agreement is supported only to negotiate private message keys,
5513 it currently cannot be used to negotiate private keys for channels,
5514 as it is not convenient for that purpose.
5516 * Fixed a minor pending callback setting bug in the function
5517 silc_client_get_client_by_id_resolve, now the function works.
5518 Affected file lib/silcclient/idlist.c.
5520 * Added function silc_net_get_local_port to get local bound
5521 port by socket. Added to lib/silcutil/silcnet.[ch].
5523 * Added `sockets' and `sockets_count' fields to the SilcClient
5524 object. They hold the sockets of the listenning sockets in
5525 the client. Listenning sockets may be for example the key
5526 agreement server. Affected file lib/silcclient/client.[ch].
5527 Added functions the silc_client_add_socket and the
5528 silc_client_del_socket. They are exported to the application
5531 * Added ~./silc/clientkeys to support other client's public keys.
5533 * Renamed verify_server_key client operation to verify_public_key
5534 and added one argument to indicate the type of the connection
5535 (server, client etc.).
5537 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5539 * Added silc_server_connection_auth_request to handle the
5540 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5541 silcd/packet_receive.[ch].
5543 * Added silc_server_send_connection_auth_request into the
5544 silcd/packet_send.c to send the connection auth request packet.
5546 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5549 * Fixed the public key authentication in responder side in the
5550 server. The `auth_data' pointer includes the SilcPublicKey
5551 not the path to the public key. Affected file silcd/protocol.c.
5553 * Implemented the public key authentication in the initiator side
5554 in the server. Affected file silcd/protocol.c.
5556 * Removed the [RedirectClient] config section from the server
5557 configuration. Is not needed and I don't want to implement it.
5559 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Cleaned up the CMODE command in the server. It now works
5562 correctly and supports all the modes defined in the protocol.
5563 Affected file is silcd/command.c.
5565 * Added `hmac_name' field to the SilcChannelEntry in the server
5566 to hold the default HMAC of the channel. It can be set when
5567 creating the channel (with JOIN command). Affected files
5570 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5571 type to indicate the change of the current cipher and hmac
5572 on the channel. Client can safely ignore the <cipher> argument
5573 (if it chooses to do so) since the CHANNEL_KEY packet will
5574 force the channel key change anyway. The <hmac> argument is
5575 important since the client is responsible of setting the new
5576 HMAC and the hmac key into use.
5578 * Fixed the CMODE command in the client library as well.
5580 * Tested CMODE command in router environment successfully.
5582 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Show the version of the remote client (or server) when connecting
5585 to the server. It is logged to the log file. Affected file
5586 is silcd/protocol.c.
5588 * Fixed the KILLED notify handling in the client library. The
5589 client must be removed from all channels when receiving the
5592 Also, do not remove the client entry when giving the KILL
5593 command but when the KILLED notify is received.
5595 * Removed silc_idlist_find_client_by_nickname from the server.
5596 Not needed anymore. Affected files silcd/idlist.[ch].
5598 * Implemented the CHANNEL_CHANGE notify type handling to the
5599 server. Affected file silcd/server.c.
5603 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Added silc_server_send_notify_invite to send the INVITE
5606 notify between routers.
5608 * Implemented the INVITE command correctly to the server.
5610 * Implemented the INVITE notify type handling in the server.
5612 * Implemented the INVITE command to the client library and on the
5615 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Added function silc_server_get_client_resolve to find the
5618 client entry by ID from all ID lists and then resolve it
5619 (using WHOIS) if it cannot be found. Affected file is
5622 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5624 * Implemented the BAN command to the client library.
5626 * The JOIN command in the server now checks the invite list
5629 * Changed the silc_command_reply_payload_encode_va and the
5630 silc_command_payload_encode_va to support that if argument is
5631 NULL it ignores and checks the next argument. Affected file
5632 lib/silccore/silccommand.c.
5634 * Added silc_server_send_notify_ban to send the BAN notify
5635 type between routers.
5637 * Chaned the silc_notify_payload_encode to support that if
5638 argument is NULL it ignores and checks the next argument.
5639 Affected file lib/silccore/silcnotify.c.
5641 * Tested ban lists in router environment successfully.
5643 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Implemented BAN command to the server, in silcd/command.[ch].
5647 * Removed the BAN and INVITE_LIST modes from the CMODE command
5650 * Added function silc_string_match to regex match two strings.
5651 Affected files lib/silcutil/silcutil.[ch].
5653 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Redefined parts of the SilcChannelEntry in the server to support
5656 the new ban and invite lists.
5658 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5660 * Redefined the INVITE command. The same command can be used to
5661 invite individuals to the channel but also to manage the invite
5662 list of the channel (to add to and remove from the invite list).
5663 Updated the protocol specs.
5665 * Added new command SILC_COMMAND_BAN that can be used to manage
5666 the ban list of the channel. Updated the protocol specs.
5668 * Removed the channel modes: the SILC_CMODE_BAN and the
5669 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5670 in the CMODE command. The equivalent features are now available
5671 using INVITE and BAN commands. Updated the protocol specs.
5673 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5674 in the network about change in the current ban list. The notify
5675 type is not used by the client.
5677 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5678 support the invite lists.
5680 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5682 * Added new function silc_string_regexify that converts string
5683 including wildcard characters into regex string that can
5684 be used by the GNU regex library. Added into the file
5685 lib/silcutil/silcutil.[ch].
5687 Added silc_string_regex_combine to combine to regex strings
5688 into one so that they can be used as one regex string by
5689 the GNU regex library. Added into the file
5690 lib/silcutil/silcutil.[ch].
5692 Added silc_string_regex_match to match two strings. It returns
5693 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5695 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5697 * Imported GNU regex to the soruce tree into lib/contrib.
5698 Fixed some compiler warning from the regex.c.
5700 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5702 * Fixed MOTD command in the server to work in router environment.
5704 * Fixed the MOTD command in the client library to support
5705 the server argument in the command.
5707 * Added `nickname_len' argument to the silc_idlist_add_client
5708 in the server, as the `nickname' argument may be binary data
5711 * Added silc_idlist_get_channels to return all channels from
5714 * Implemented LIST command to the server. Affected file is
5717 * Implemented the LIST command to the client library and on the
5720 * Added [<user count>] argument to the LIST command reply.
5721 With private channels the user count is not shown.
5723 * Updated TODO and README.
5725 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * The client entry's data.registered must be TRUE even with
5728 global client entry on global client list. The data.registered
5729 is used to check whether the client is anymore in the network,
5730 for example with WHOWAS command so it must be valid.
5732 * Fixed the WHOWAS command in the server. It now actually works
5733 in router environment. Added function into silcd/command_reply.c
5734 silc_server_command_reply_whowas_save.
5736 * Added silc_idlist_purge function to the silcd/idlist.c
5737 to periodically purge the ID Cache.
5739 * Fixed INFO command in the server. It works now in router
5740 environment. Added <server name> argument to the INFO command
5741 reply. Updated the protocol specs.
5743 * Fixed minor bug in silc_idcache_purge to not purge if the
5744 expire value is zero.
5746 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5747 they were buggy because of the WHOWAS information.
5749 * Fixed local command MSG to handle the async resolving of
5750 the remote client properly. It used to fail the first MSG.
5751 Affected file silc/local_command.c.
5753 * Added `data_len' field to SilcIDCache context.
5755 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Update TODO. Todo in commands in the server.
5759 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5762 used by routers as broadcast packet to inform other routers
5763 about the changed user mode.
5765 Implemented the notify handling in the server. Affected file is
5766 silcd/packet_receive.c. Added the function
5767 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5769 * Added new generic Channel Payload and deprecated the New Channel
5770 Payload. The New Channel Payload is now the generic Channel
5773 * Added new argument `mode' to the silc_server_send_new_channel
5774 as it is required in the Channel Payload now.
5776 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5777 and created a new and real SilChannelPayload to represent the
5778 new generic Channel Payload. Implemented the encode/decode
5779 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5781 * Added silc_server_get_client_channel_list to return the list
5782 of channels the client has joined for WHOIS command reply.
5783 Affected file silcd/server.[ch].
5785 * Implemented the channel list sending in the WHOIS command reply
5786 in server and in the client.
5788 Implemented the channel list displaying on the user interface
5789 as well. Affected file silc/client_ops.c.
5791 * Added silc_channel_payload_parse_list to parse list of Channel
5792 Payloads. It returns SilcDList list of SilcChannelPayloads.
5793 Client for example can use this function to parse the list of
5794 channels it receives in the WHOIS command reply. The caller
5795 must free the list by calling silc_channel_payload_list_free.
5796 Affected files lib/silccore/silcchannel.[ch].
5798 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added one new argument <user mode> to the WHOIS command reply
5801 to return the mode of the user in SILC. Updated the protocol
5804 Implemented it to the server and client.
5806 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed the mode printing on the user interface on joining.
5809 Affected file silc/client_ops.c.
5811 * Implemented the UMODE command and user modes in general to the
5812 client library and to the user interface.
5814 * Implemented the UMODE command to the server.
5816 * The server now sends UNKNOWN_COMMAND error status if client sends
5817 unknown command. Affected file silcd/command.c.
5819 * All server commands now handle the command identifier the right
5820 way when sending the command reply to the client. The client can
5821 use to identify the command replies with the identifier.
5823 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Added silc_server_get_client_route to resolve the route to
5826 the client indicated by the client ID. Affected file is
5829 * Added silc_server_relay_packet as general function to relay
5830 packet to arbitrary destination. This deprecates functions
5831 like _send_private_message_key, _relay_notify etc. Affected
5832 file is silcd/packet_send.[ch].
5834 Removed silc_server_send_key_agreement,
5835 silc_server_send_private_message_key and
5836 silc_server_packet_relay_notify functions from the file
5837 silcd/packet_send.[ch].
5841 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5842 server. Affected file silcd/packet_receive.[ch].
5844 * Implemented the KILL command to the client. Implemented the
5845 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5846 Affected files lib/silcclient/command[_reply].c and
5847 lib/silcclient/client_notify.c. Implemented the KILL notify
5848 printing in the user inteface.
5850 * Fixed a lot silc_parse_nick memory leaks from the client
5851 library in the file lib/silcclient/command.c.
5853 * Changed the silc_server_send_notify_on_channels's `sender'
5854 argument from SilcSocketConnection to SilcClientEntry to
5855 check the sender as entry and not as connection object and not
5856 to send to the client provided as argument. The affected file
5857 is silcd/packet_send.[ch].
5859 * The notify packets that are destined directly to the client used
5860 to not to be processed by the server. Now changed that and the
5861 server processes all notify packets. After relaying the packet
5862 to the client the notify packet is processed in the server.
5864 * The silc_server_free_client_data now checks whether there is
5865 pending outgoing traffic for the client and purges the data to
5866 the network before removing the client entry.
5868 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5871 an client is killed from the SILC Network. Updated the protocol
5874 Added new function silc_server_send_notify_killed to the
5875 silcd/packet_send.[ch].
5877 * Added function silc_server_packet_relay_notify to relay notify
5878 packets that are destined directly to a client. In this case
5879 the server does not process the notify packets but merely relays
5880 it to the client. Affected file silcd/packet_send.[ch].
5882 Added also silc_server_packet_process_relay_notify to check
5883 whereto relay the notify. Affected file is
5884 silcd/packet_receive.[ch].
5886 * Implemented the KILL command to the server.
5890 * Added the backup schema desgined last fall to the protocol
5891 specs for everyone to see. The specification is in the
5892 *-spec-xx.txt draft and the packet type definitions for the
5893 backup routers is in *-pp-xx.txt draft. Thusly, added also
5894 new packet type SILC_PACKET_CELL_ROUTERS.
5896 * A big security problem in the implementation discovered. The
5897 signoff of an client did not cause new channel key generation
5898 which it of course should've done. The channel keys must be
5899 always re-generated when client leaves (or signoffs) the channel.
5900 The silc_server_remove_from_channels funtion now handles
5901 the channel key re-generation.
5903 * Added `sender' argument to the silc_server_send_notify_on_channels
5904 to not to send the client provided as argument. Affected file
5905 silcd/packet_send.[ch].
5907 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Implemented OPER and SILCOPER commands into the server and
5912 * Added silc_auth_verify and silc_auth_verify_data to verify
5913 the authentication directly from the authentication payload.
5914 It supports verifying both passphrase and public key based
5915 authentication. Affected file lib/silccore/silcauth.[ch].
5917 * Added `hash' field to the SilcIDListData structure. It is the
5918 hash negotiated in the SKE protocol. Affected file is
5921 * Slight redesigning of the SilcAuthPayload handling routines.
5922 Do not send SilcPKCS but SilcPublicKey as argument.
5924 * Implemented the public key authentication support to the
5925 serverconfig. The public key is loaded from the provided path
5926 and saved as authentication data to void * pointer. Thus,
5927 changed the unsigned char *auth_data to void *auth_data;
5929 * Fixed SHUTDOWN command to send the reply before the server
5930 is shutdown. :) Affected file silcd/command.c.
5932 * Fixed fatal bug in CONNECT command. The hostname was invalid
5933 memory and server crashed. Affected file silcd/command.c.
5935 * Fixed fatal bug in CLOSE command. The server_entry became
5936 invalid but was referenced later in the command. Affected file
5939 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Fixed fatal bug in failure packet handling. Server ignored
5942 the failure and thus crashed when it came.
5946 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5949 that the command may be executed only once in (about) 2 seconds.
5950 The old SILC_CF_LAG flag is same but allows command bursts up
5951 to five before limiting.
5953 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5954 server code. Various commands now includes the CF_LAG_STRICT
5955 flag to disallow any kind of miss-use of the command.
5957 * Fixed the silc_buffer_unformat to not to allocate any data
5958 if the length of the data is zero. It used to allocate the
5959 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5961 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Changed the format of AdminConnection configuration section
5964 in the server. Added username of the admin to the format.
5965 Affected files silcd/serverconfig.[ch].
5967 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5968 to return admin configuration data by host, username and/or
5971 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Implemented WHOWAS command to the server. Added the functions:
5975 silc_server_command_whowas_parse,
5976 silc_server_command_whowas_send_reply,
5977 silc_server_command_whowas_from_client and
5978 silc_server_command_whowas_from_server
5980 * Added <Client ID> argument to the WHOWAS command reply. Updated
5981 the protocol specs accordingly.
5983 * Implemented WHOWAS command and command_reply to the client
5986 Implemented the WHOWAS printing on the user interface.
5988 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added new argument to the WHOWAS command reply, the real name.
5991 It is an optional argument. Updated the protocol specs.
5993 * Added SilcIDCacheDestructor callback that is registered when
5994 the SilcIDCache is allocated. The callback is called when
5995 an cache entry in the ID Cache expires, or is purged from the
5996 cache. Added into lib/silccore/idcache.[ch].
5998 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5999 to destruct the client entries when the cache entry expires.
6000 Other ID Cache's in server and in the client library ignores
6003 * If the ID Cache entry's `expire' field is zero then the entry
6004 never expires. Added boolean `expire' argument to the
6005 silc_idcache_add function in the lib/silccore/idcache.[ch].
6006 If it is TRUE the default expiry value is used.
6008 * Added silc_server_free_client_data_timeout that is registered
6009 when client disconnects. By default for 5 minutes we preserve
6010 the client entry for history - for WHOWAS command.
6012 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Added support to the server to enforce that commands are not
6015 executed more than once in 2 seconds. If server receives
6016 commands from client more frequently, timeout is registered
6017 to process the commands. Affected file silcd/command.c.
6018 Added new function silc_server_command_process_timeout.
6020 * Changed NICK_NOTIFY handling in client library to check that
6021 if the client's nickname was changed, so there is no need to
6022 resolve anything from the server.
6024 * Removed error printing from the WHOIS and IDENTIFY commands.
6025 If error occurs then it is ignored silently in the client library.
6026 The application, however, may map the received error to
6027 human readable error string. The application currently maps
6028 the NO_SUCH_NICKNAME error to string.
6030 * Made the command status message public to the application. Moved
6031 them from lib/silcclient/command_reply.c to
6032 lib/silcclient/command_reply.h. The application can map the
6033 received command status to the string with the
6034 silc_client_command_status_message function.
6036 * Added check to the server to check that client's ID is same
6037 as the Source ID in the packet the client sent. They must
6040 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Added dist-bzip hook to the Makefile.am to make bzip2
6043 compressed distributions.
6045 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Server now enforces the maximum length for the nickname and
6048 the channel as protocol specification dictates. 128 bytes for
6049 nickname and 256 bytes for channel name.
6051 * Moved the WHOIS printing to the application. The client libary
6052 does not print out the WHOIS information anymore, the application
6053 must do it. Renamed silc_client_command_reply_whois_print to
6054 the silc_client_command_reply_whois_save.
6056 The client's idle time is also sent to the application now, and
6057 the idle is shown on screen.
6059 * Added silc_client_command_reply_identify_save to save the
6060 received IDENTIFY entries.
6062 * Do not check for channel private keys in message sending and
6063 reception if the channel does not have the PRIVKEY mode set.
6064 Affected file lib/silclient/client_channel.c.
6066 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6069 just surfaced after chaning the JOIN procedure.
6071 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6073 * Added silc_client_get_clients_by_list to get client entries
6074 from Client ID list, that is returned for example by JOIN
6075 and USERS command replies. The application should use this
6076 function for example when JOIN command reply is received to
6077 resolve the clients already on the channel (library does not
6078 do that anymore as USERS command reply is not used in the JOIN
6079 procedure anymore). Affected files lib/silcclient/silcapi.h and
6080 lib/silcclient/idlist.c.
6082 * JOIN command reply and USERS command reply returns now SilcBuffer
6083 pointers instead of unsigned char pointers when returning
6084 the client list and mode list.
6086 * Added <Client ID> argument to the JOIN command reply, mainly
6087 for the server to identify for which client the command was
6088 originally sent. Updated protocol specs accordingly.
6090 * Added SilcDlist private_key pointer to the SilcChannelEntry
6091 in the client to support the channel private keys. Affected
6092 file is lib/silcclient/idlist.h.
6094 * Added SilcChannelPrivateKey argument to the function
6095 silc_client_send_channel_message so that application can choose
6096 to use specific private ke if it wants to. If it is not provided,
6097 the normal channel key is used, unless private keys are set.
6098 In this case the first (key that was added first) is used
6099 as the encryption key.
6101 * Implemented the support for channel private key handling.
6102 Implemented the following functions:
6104 silc_client_add_channel_private_key,
6105 silc_client_del_channel_private_keys,
6106 silc_client_del_channel_private_key,
6107 silc_client_list_channel_private_keys and
6108 silc_client_free_channel_private_keys
6110 Affected file lib/silcclient/client_channel.c.
6112 * Added the support for the private keys in the channel message
6113 sending and encryption and in the message reception and
6114 decryption. Affected funtions are
6115 silc_client_send_channel_message and silc_client_channel_message.
6117 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Added SKE's key verify callback to the client library's
6120 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6122 * Removed the statement that server (or router) must send USERS
6123 command reply when joining to the channel so that the client
6124 knows who are on the channel. Instead, the client list and
6125 client's mode list is now sent in the JOIN command reply to the
6126 client who joined channel. This is better solution.
6128 * Added function silc_server_get_users_on_channel and function
6129 silc_server_save_users_on_channel to the silcd/server.[ch].
6131 * Removed function silc_server_command_send_users from the
6134 * Do not show topic on the client library anymore. The topic is
6135 sent in the command reply notify to the application and the
6136 application must show the topic now.
6138 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added client searching by nickname hash into the IDENTIFY and
6141 WHOIS commands in the server as they were clearly missing from
6142 them. Affected file is silcd/command.c.
6144 * Fixed a bug in private message receiving in the client library.
6145 The remote ID was freed and it wasn't supposed, now it is
6148 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Minor fix to the channel payload; allocate the data area, as it
6151 needs to be of specific length.
6153 * If the key agreement port is zero then the operating
6154 system will define the bound port. Affected files are
6155 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6157 * Added new function silc_channel_payload_decrypt into the file
6158 lib/silccore/silcchannel.[ch].
6160 * Moved the channel message etc, check from silc_packet_decrypt
6161 to applications. The library calls now a generic
6162 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6163 when the packet is either normal or special. This was done to
6164 allow more wide range of checking that was not allowed when
6165 the code was in library. Now applications can do virtually any
6166 checks to the packet and return to the library the decision how
6167 the packet should be processed. Affected files are
6168 lib/silccore/silcpacket.[ch].
6170 Added silc_server_packet_decrypt_check to the server and
6171 silc_client_packet_decrypt_check to the client library.
6173 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6174 to send with specified source and destination information.
6176 * Channel message delivery between routers was broken after the
6177 channel key distribution was fixed earlier. The channel key
6178 was used be to distributed to other routers as well which is not
6179 allowed by the protocol. Now this is fixed and channel keys
6180 really are cell specific and the channel message delivery between
6181 routers comply with the protocol specification.
6183 * Fixed various commands in server to check also the global list
6184 for the channel entry and not just the local list. The affected
6185 file silcd/command.c.
6187 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Added assert()s to buffer formatting and unformatting routines
6190 to assert (if --enable-debug) when error occurs. Affected
6191 file: lib/silcutil/silcbuffmt.c.
6193 * Changed to auto-reconnect to check whether the remote host is
6194 router and register the re-connect timeout if it is. It used
6195 to check that whether we are normal server, but router must do
6196 auto-reconnect with another router as well. Affected file
6199 * Removed the [<key len>] option from CMODE command as the cipher
6200 name decides the key length, nowadays. See the defined ciphers
6201 from the protocol specification.
6203 * Added [<hmac>] option to the CMODE command to define the HMAC
6204 for the channel. Added SILC_CMODE_HMAC channel mode.
6206 * Added [<hmac>] option for the JOIN command so that user can
6207 select which HMAC is used to compute the MACs of the channel
6210 * Added Hmac field to the Channel Message Payload. The integrity
6211 of plaintext channel messages are now protected by computing
6212 MAC of the message and attaching the MAC to the payload. The
6213 MAC is encrypted. Now, it is clear that this causes some
6214 overhead to the size of the packet but rationale for this is that
6215 now the receiver can verify whether the channel message decrypted
6216 correctly and also when private keys are set for the channel the
6217 receiver can decrypt the packet with several keys and check from
6218 the MAC which key decrypted the message correctly.
6220 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6221 lib/silccrypt/silccipher.[ch].
6223 * Added silc_hash_len to return the digest length into the
6224 lib/silcrypt/silchash.[ch].
6226 * Rewrote parts of Silc Channel Payload interface in the
6227 lib/silccore/silcchannel.[ch]. The encode function now also
6228 encrypts the packet and parse function decrypts it.
6230 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Fixed a minor formatting bug in the SKE's key material processing.
6233 It actually might have processed the keys wrong way resulting
6236 * Redefined the mandatory HMAC algorithms and added new algorithms.
6237 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6238 and hmac-md5 truncated to 96 bits. The mandatory is now
6239 hmac-sha1-96. Rest are optional (including the one that used
6240 to be mandatory). Rationale for this is that the truncated HMAC
6241 length is sufficient from security point of view and can actually
6242 make the attack against the HMAC harder. Also, the truncated
6243 HMAC causes less overhead to the packets. See the RFC2104 for
6246 * Added new [hmac] configuration section. The SKE used to use
6247 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6248 is of course wrong. The official names that must be proposed in
6249 the SKE are the ones defined in the protocol specification
6250 (hmac-sha1-96 for example). The user can configure any hmac
6251 using any hash function configured in the [hash] section. At
6252 least, the mandatory must be configured.
6254 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6256 * Added HMAC list to the SKE proposal list. It has now both
6257 hash algorithm list and HMAC list. This makes the protocol
6258 incompatible with previous versions. The SKE now seems to work
6259 the way it is supposed to work, for the first time actually.
6261 * Defined plain Hash algorithms to the protocol specification.
6264 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Implemented support for key agreement packets into the server.
6267 Added functions silc_server_key_agreement and
6268 silc_server_send_key_agreement. Other than these functions,
6269 server has nothing to do with this packet.
6271 * Added support for private message key packets into the server.
6272 Added functions silc_server_private_message_key and
6273 silc_server_send_private_message_key.
6277 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6278 called in the protocol's final callback instead in the END
6279 protocol state. This makes a little more sense and in the same
6280 time in client we can use the same protocol routines for normal
6281 key exchange and to key agreement packet handling as well.
6283 * Added to both client's and server's KE protocol context the
6284 SilcSKEKeyMaterial pointer to save the key material. We will
6285 bring the key material to the protocol's final callback by doing
6286 this. The final callback must free the key material.
6288 * Added SKE's packet_send callback into client's KE protocol
6289 context so that the caller can choose what packet sending function
6290 is used. This way we can use different packet sending when
6291 doing normal SKE when doing key agreement packet handling (in
6292 the key agreement packet handling we do not want to encrypt
6295 * Implemented the responder side of the key agreement routines
6296 in the client. The client can now bind to specified port and
6297 accept incoming key negotiation. The key material is passed
6298 to the application after the protocol is over.
6300 * Implemented the processing of incoming Key Agreement packet
6301 in the client. Added function silc_client_key_agreement to
6304 * Implemented the intiator side of the key agreement routines
6305 in the client. The client can now initiate key agreement with
6306 another remote client. The key material is passed to the
6307 application after the protocol is over.
6309 * Created client_keyagr.c to include all the key agreement
6312 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6313 SILC_TASK_CALLBACK except that it is not static.
6315 * Created client_notify.c and moved the Notify packet handling
6316 from the client.[ch] into that file.
6318 * Created client_prvmsg.c and moved all private message and
6319 private message key routines from the client.[ch] into that file.
6321 * Create client_channel.c and moved all channel message and
6322 channel private key routines from the client.[ch] into that file.
6324 * Changed silc_client_get_client_by_id_resolve to resolve with
6325 WHOIS command instead of IDENTIFY command, in the file
6326 lib/silclient/idlist.c.
6328 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Implemented the SKE's responder side to the Client library.
6332 * When FAILURE is received to the protocol do not trust it
6333 blindly. Register a timeout to wait whether the remote closes
6334 the connection as it should do it, only after that process the
6335 actual failure. This was changed to both client and server.
6337 * Added client_internal.h to include some of the structures
6338 there instead of client.h in lib/silcclient/.
6340 * Added function silc_task_unregister_by_callback to unregister
6341 timeouts by the callback function.
6343 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6345 * Some "Incomplete WHOIS info" errors has been appearing on the
6346 log files. Took away the entry->userinfo check from WHOIS
6347 reply sending. The entry->userinfo is now " " if client did not
6348 provide one. I thought this was fixed earlier but something
6349 is wrong still. Let's see if the error still appears.
6351 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Fixed a minor bug in the login when the channel key is
6354 re-generated in the server. It used to generate the key in
6355 wrong order and thus caused problems in the channel traffic.
6357 * Fixed a minor bug in channel key distsribution after
6358 KICK command. The key was not sent to the router even though
6361 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Added silc_ske_process_key_material_data as generic routine
6364 to process any key material as the SILC protocol dictates. The
6365 function is used by the actual SKE library but can be used by
6366 applications as well. This relates to the private message keys
6367 and the channel private keys since they must be processed the
6368 same way the normal SILC session keys. The protocol dictates
6369 this. Affected files: lib/silcske/silcske.[ch].
6371 Added also silc_ske_free_key_material to free the
6372 SilcSKEKeyMaterial structure.
6374 * Defined silc_cipher_set_key function to set the key for
6375 cipher without using the object's method function. The affected
6376 files: lib/silccrypt/silccipher.[ch].
6378 * Implemented silc silc_client_add_private_message_key,
6379 silc_client_add_private_message_key_ske,
6380 silc_client_del_private_message_key,
6381 silc_client_list_private_message_keys and
6382 silc_client_free_private_message_keys functions in the
6385 Added functions silc_client_send_private_message_key to send
6386 the Private Message Key payload and silc_client_private_message_key
6387 to handle incoming Private Message Key payload.
6389 * Added Cipher field to the Private Message Key payload to set
6390 the cipher to be used. If ignored, the default cipher defined
6391 in the SILC protocol (aes-256-cbc) is used.
6393 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Removed lib/silcclient/ops.h file.
6397 Redefined parts of the SILC Client Library API. Created new
6398 file silcapi.h that deprecates the ops.h file and defines the
6399 published Client Library API. Defined also private message key
6400 API and channel private key API into the file.
6402 This is the file that the application must include from the
6403 SILC Client Library. Other files need not be included by
6404 the application anymore.
6406 * Added new key_agreement client operation callback and also
6407 defined the Key Agreement library API for the application.
6409 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6412 is used by clients to request key negotiation between another
6413 client in the SILC network. If the negotiation is started it
6414 is performed using the SKE protocol. The result of the
6415 negotiation, the secret key material, can be used for example
6416 as private message key.
6418 Implemented the Key Agreement payload into the files
6419 lib/silccore/silauth.[ch].
6421 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6423 * Redefined ciphers for the SILC protocol. Added some new ciphers
6424 and defined the key lengths for the algorithms. Changed the
6425 code accordingly. The default key length is now 256 bits.
6427 * Fixed SKE key distribution function silc_ske_process_key_material
6428 when the key length is more than 128 bits. The default key
6429 length in SILC is now 256 bits.
6431 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6432 to indicate unsupported algorithm.
6434 * Renamed rijndael.c to aes.c and all functions as well.
6436 * Fixed a long standing channel key setting bug in client library.
6437 Weird that it has never surfaced before.
6439 * Fixed bug in channel deletion. If the entire channel is removed
6440 then it must also delete the references of the channel entry
6441 from the client's channel list as the client's channel entry and
6442 the channel's client entry share same memory.
6444 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Implemented CONNECT and SHUTDOWN commands in the client.
6448 * Implemented CLOSE command to the client.
6450 * Added the function silc_idlist_find_server_by_name into the
6451 files silcd/idlist.[ch].
6453 Added the function silc_idlist_find_server_by_conn into the
6454 files silcd/idlist.[ch].
6456 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6458 * DIE command was renamed to SHUTDOWN. Updated the both code
6461 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6462 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6464 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6467 * Added function silc_server_create_connection function to create
6468 connection to remote router. My server implementation actually
6469 does not allow router to connect to normal server (it expects
6470 that normal server always initiates the connection to the router)
6471 so the CONNECT command is only good for connecting to another
6474 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6477 or some other client was kicked from the channel.
6479 Implemented the handling of the notify type to both client
6482 Implemented silc_server_send_notify_kicked to send the KICKED
6483 notify. It is used to send it to the server's primary router.
6485 * Implemented the KICK command into server and client.
6487 * Added `query' argument to the silc_idlist_get_client function
6488 to indicate whether to query the client from server or not if
6491 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6492 to indicate that the client is not channel founder.
6496 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Removed the rng context from SilcPacketContext structure and
6499 changed that the packet routine uses the Global RNG API.
6501 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6503 * Added support for quit message that client can "leave" on the
6504 channel when it quits the SILC. It is ditributed inside the
6505 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6507 Added silc_server_free_client_data that will take the
6508 signoff message as argument.
6510 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6512 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Updated parts of the protocol specification to keep it up
6517 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6519 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6520 payloads in one packet.
6522 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6523 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6524 use now the new List flag.
6526 * Also deprecated the following packet types: REPLACE_ID,
6527 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6529 * Added list support for Notify packet in server.
6531 * Added silc_server_send_notify_channel_change to send the
6532 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6533 the silc_server_send_replace_id.
6535 * Added silc_server_send_notify_nick_change to send the
6536 NICK_CHANGE notify type. Deprecates the function
6537 silc_server_send_replace_id.
6539 * Added silc_server_send_notify_join to send the JOIN notify type.
6540 Deprecates the function silc_server_send_new_channel_user.
6542 * Added silc_server_send_notify_leave to send LEAVE notify type.
6543 Deprecates the function silc_server_send_remove_channel_user.
6545 * Added silc_server_send_notify_cmode and
6546 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6547 types. Deprecates the silc_server_send_set_mode function.
6549 * Added SERVER_SIGNOFF notify type to indicate that server has
6550 quit. This means that all clients on the channel from that
6551 server will drop. This can be also used when netsplit happens.
6553 Deprecated REMOVE_ID packet type since it is not needed anymore
6556 Added silc_server_send_notify_server_signoff to send the
6557 SERVER_SIGNOFF notify type. Deprecates the function
6558 silc_server_send_remove_id.
6560 Added also silc_server_send_notify_signoff to send the
6561 SIGNOFF notify type.
6563 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6564 SILC protocol from this day on. Changed the protocol
6565 specification as well.
6567 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6568 notify type. It is used between routers to notify about
6569 topic changes on a channel.
6571 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6574 * Partly updated the protocol specification to comply with the
6575 changes now made. It is still though a bit outdated.
6577 * The JOIN notify type now takes one extra argument <Channel ID>.
6578 The packet used to be destined to the channel but now the
6579 JOIN type may be sent as list thus it is impossible to
6580 destine it to any specific channel. By adding this argument
6581 it is again possible.
6583 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Added CREDITS file. The CHANGES and CREDITS file will appear
6586 in the distribution as well.
6588 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6591 types in the server's silcd/packet_receive.c.
6593 * Implemented CMODE and CUMODE to work in router environment.
6595 * Fixed minor encoding and decoding buglet from the
6596 lib/silccore/silcmode.c.
6598 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6601 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6603 * Changed all SilcConfigServer* and silc_config_server* to
6604 SilcServerConfig* and silc_server_config*, respectively.
6607 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Associated the ID (client or server ID) to the Authentication
6610 Payload to avoid any possibility of forging. Updated the
6611 protocol specification and the code accordingly.
6613 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6615 * The RSA key length is now save to the RsaKey context in the
6616 key generation process in lib/silccrypt/rsa.c. The key length
6617 is now used to figure out the maximum size of the block allowed
6618 to be encrypted/signed.
6620 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6621 is equivalent to the silc_mp_mp2bin but does not allocate any
6624 * Changed silc_mp_mp2bin API to take length argument. If it is
6625 non-zero then the buffer is allocated that large. If zero, then
6626 the size is approximated using silc_mp_sizeinbase, which however
6629 * Created Global RNG API which is global RNG that application can
6630 initialize. After initializing, any routine anywhere in the
6631 code (including library) can use RNG without allocating a new
6632 RNG object. This was done to allow this sort of use of the
6633 RNG in code that has no chance to allocate RNG object. All
6634 applications currently allocate this and many routines in the
6635 library use this. Affected file lib/silccrypt/silcrng.[ch].
6637 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6638 it to use the Global RNG API.
6640 * Defined Authentication Payload into protocol specification that
6641 is used during SILC session to authenticate entities. It is
6642 used for example by client to authenticate itself to the server
6643 to obtain server operator privileges.
6645 Implemented this payload into the lib/silccore/silcauth.[ch].
6646 Implemented also routines for public key based authentication
6647 as the new protocol specification dictates.
6649 Moved definitions of different authentication methods from
6650 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6652 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6653 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6654 silc_pkcs_verify_with_hash functions into the file
6655 lib/silccrypt/silcpkcs.[ch].
6657 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * The client entry's userinfo pointer must be always valid.
6660 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6661 will fail since it requires the userinfo. Now, the userinfo
6662 is allocated as "" if actual userinfo does not exist. Actually,
6663 it must exist and it is totally Ok to drop client connections
6664 that does not announce the userinfo. However, we will make
6665 this workaround for now.
6667 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6668 to return the remote port by socket.
6670 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6672 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6673 SILC_SERVER_PENDING_EXEC and added an new macro
6674 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6675 data or when error occurs while processing the pending command.
6677 Added new argument `destructor' into silc_server_command_pending
6678 and to the SilcServerCommandPending object. This destructor is
6679 now called after calling the pending callback or if error occurs
6680 immediately. If error occurs the actual pending callback won't
6681 be called at all - only the destructor. The destructor may be
6682 NULL if destructor is not needed.
6684 All this applies for client library code as well. Similar
6685 changes were made there as well for the pending commands.
6687 In the client, the application must now allocate the
6688 SilcClientCommandContext with the silc_client_command_alloc
6691 * Added reference counter to the SilcServerCommandContext. Added
6692 function silc_server_command_alloc and silc_server_command_dup
6695 Same type of functions added to the client library for the same
6698 * Removed the cmd_ident from IDListData away since it is now
6699 global for all connections. It is the command identifier used
6700 in command sending and with pending commands. The affected file
6703 * Added reference counter to the SilcSocketConnection objecet to
6704 indicate the usage count of the object. The object won't be
6705 freed untill the reference counter hits zero. Currently only
6706 server uses this, and client ignores it. The client must be
6707 set to use this too later. The affected files are
6708 lib/silccore/silcsockconn.[ch]. Added also the function
6709 silc_socket_dup to increase the reference counter.
6711 This was mainly added because it is possible that the socket
6712 is removed underneath of pending command or other async
6713 operation. Now it won't be free'd and proper DISCONNECTING
6714 flags, etc. can be set to avoid sending data to connection that
6715 is not valid anymore.
6717 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6718 the connection. After that it sets SILC_SET_DISCONNECTED.
6719 It is, however, possible that the socket data is not still freed.
6720 The silc_server_packet_process now checks that data is not
6721 read or written to connection that is DISCONNECTED. The socket
6722 get's freed when the reference counter hits zero.
6724 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Changed the client operation API: channel_message operation's
6727 `sender' is now the client entry of the sender, not the nickname
6728 and the `channel' is the channel entry, not the channel name.
6730 In the private_message operation the `sender' is now also the
6731 client entry of the sender not the nickname.
6733 Affected file is lib/silcclient/ops.h and all applications
6734 using the client operations.
6736 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Moved the calling of ops->connect() from connect_to_server_final
6739 into receive_new_id functin since that is the point when the
6740 client is actually allowed to send traffic to network. The
6741 affected file is lib/silcclient/client.c.
6743 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6745 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6746 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6747 (if needs broadcasting) instead of broadcasting the packets one
6748 by one which would make a burst in the network traffic.
6750 * Added `broadcast' argument to the functions in silcd/server.[ch]
6751 silc_server_create_new_channel[_with_id] to indicate whether
6752 to send New Channel packet to primary router.
6754 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6756 * Added new function into the silcd/server.[ch] files:
6757 silc_server_create_new_channel_with_id to create new channel with
6758 already existing Channel ID.
6760 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6761 lib/silccore/silcpacket.h. This packet is used t send list of
6762 Set Mode payloads inside one packet. Server uses this to set
6763 the modes for the channels and clients on those channels, that it
6764 announced to the router when it connected to it. The protocol
6765 specification has been updated accordingly.
6767 * The silc_server_new_channel did not handle the packet coming
6768 from normal server as it normally does not send that. However,
6769 when it announces its channels it does send it. Implemented
6770 the support for that.
6772 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6773 into the file lib/silccore/id.h.
6775 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6777 * Fixed memory leaks in the functions silc_idlist_del_client,
6778 silc_idlist_del_channel and silc_idlist_del_server in the file
6779 silcd/idlist.c. All of those leaked like a sieve.
6781 * Fixed some small memory leaks in the client's function
6782 silc_client_notify_by_server.
6784 * Added functions into silcd/server.c: silc_server_announce_clients,
6785 silc_server_announce_channels and silc_server_announce_server.
6786 These functions are used by normal and router server to announce
6787 to its primary router about clients, channels and servers (when
6788 router) that we own. This is done after we've connected to the
6791 These functions effectively implements the following packet types:
6792 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6793 and SILC_PACKET_NEW_ID_LIST.
6795 * Added new functions into the silcd/packet_receive.[ch]:
6796 silc_server_new_id_list, silc_server_new_channel_list and
6797 silc_server_new_channel_user_list to handle the incoming
6798 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6800 * Added support of changing Channel ID in the function
6801 silc_server_replace_id. If the server that announces a channel
6802 to the router already exists in the router (with same name but
6803 with different Channel ID), router is responsible to send
6804 Replace ID packet to the server and force the server to change
6805 the Channel ID to the one router has.
6807 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6808 client that the Channel ID has been changed by the router. The
6809 normal server sends this to the client. Client must start using
6810 the new Channel ID as the channel's ID.
6812 Implemented handling of this new type into lib/silcclient/client.c
6813 into the function silc_client_notify_by_server.
6815 * Added new function silc_idlist_replace_channel_id into the files
6816 silcd/idlist.[ch] to replace the Channel ID.
6818 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Call silc_server_command_identify_check always when processing
6821 the IDENTIFY command in silcd/command.c
6823 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6825 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6826 send keepalive packets. The packet can be sent by clients,
6827 servers and routers.
6829 Added function silc_socket_set_heartbeat into the file
6830 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6831 If not set, the heartbeat is not performed. The actual
6832 heartbeat is implemented in the low level socket connection
6833 library. However, application is responsible of actually
6836 Added silc_server_send_heartbeat to send the actual heartbeat
6837 packet into silcd/packet_send.[ch]. Server now performs
6838 keepalive with all connections.
6840 * Added silc_task_get_first function into lib/silcutil/silctask.c
6841 to return the timeout task with shortest timeout. There was a bug
6842 in task unregistration that caused problems. TODO has been
6843 updated to include that task system must be rewritten.
6845 * The client library will now resolve the client information when
6846 receiving JOIN notify from server for client that we know but
6847 have incomplete information.
6849 * Rewrote parts of silc_server_remove_from_channels and
6850 silc_server_remove_from_one_channel as they did not remove the
6851 channel in some circumstances even though they should've.
6853 * Encryption problem encountered in server:
6855 The LEAVE command used to send the Channel Key packet to the
6856 router immediately after generating it. However, the code
6857 had earlier sent Remove Channel user packet but not immediately,
6858 ie. it was put to queue. The order of packets in the router
6859 was that Channel Key packet was first and Remove Channel User
6860 packet was second, even though they were encrypted in the
6861 reverse order. For this reason, MAC check failed. Now, this
6862 is fixed by not sending the Channel Key packet immediately but
6863 putting it to queue. However, this is more fundamental problem:
6864 packets that are in queue should actually not be encrypted
6865 because packets that are sent immediately gets encrypted
6866 actually with wrong IV (and thus MAC check fails). So, packets
6867 that are in queue should be encrypted when they are sent to
6868 the wire and not when they put to the queue.
6870 However, the problem is that the current system has not been
6871 designed to work that way. Instead, the packet is encrypted
6872 as soon as possible and left to the queue. The queue is then
6873 just purged into wire. There won't be any fixes for this
6874 any time soon. So, the current semantic for packet sending
6877 o If you send packet to remote host and do not force the send
6878 (the packet will be in queue) then all subsequent packets to the
6879 same remote host must also be put to the queue. Only after the
6880 queue has been purged is it safe again to force the packet
6883 o If you send all packets immediately then it safe to send
6884 any of subsequent packets through the queue, however, after
6885 the first packet is put to queue then any subsequent packets
6886 must also be put to the queue.
6888 Follow these rules and everything works fine.
6890 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Added new function silc_server_remove_clients_by_server to
6893 remove all client entries from ID list when the server connection
6894 is lost. In this case it is also important to invalidate all
6895 client entires as they hold the invalid server entry. This
6896 fixes fatal bug when server has lost connection and will reconnect
6899 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Made some sanity checks to silc_server_daemonise like to check
6902 whether the requested user and group actually exists.
6904 * Added sanity check to SKE's silc_ske_responder_finish to check
6905 that the public and private key actually is valid.
6907 * Invalidate the client's nickname when receiving Replace ID
6908 packet and the Client ID is being replaced. This means that the
6909 server will query the nickname if someone needs it (client)
6912 * Sort the ID Cache in client library when the ID Cache data
6913 has changed (needs sorting).
6915 * Do not allow for SILC client to create several connections to
6916 several servers. The client does not support windows right now
6917 and generating multiple connections causes weird behaviour.
6919 Irssi-silc client does support windows and can handle several
6920 connections without problems, see: www.irssi.org and SILC plugin.
6922 * Fixed some places where client was added to the IDList. The
6923 rule of thumb is following (in order to get everything right):
6924 If the client is directly connected local client then the
6925 `connection' argument must be set and `router' argument must be
6926 NULL to silc_idlist_add_client function. If the client is not
6927 directly connected client then the `router' argument must
6928 bet set and the `connection' argument must be NULL to the
6929 silc_idlist_add_client function.
6931 * The funtion silc_server_packet_send_local_channel actually did
6932 not check whether the client was locally connected or not. It
6933 does that now. Fixed a bug related to LEAVE command.
6935 * Fixed Remove Channel User payload parsing bug in server's
6936 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6938 * The server's silc_server_save_channel_key now checks also the
6939 global ID list for the channel as it might not be in the local
6940 list. Fixed a bug related to LEAVE command.
6942 * Is this the end of the [<unknown>] buglet that has been lurking
6943 around for a long time? A little for loop fix in server's
6944 silc_server_command_whois_parse that is used by both IDENTIFY
6945 and WHOIS command. At least, this was a clear bug and a cause
6946 of one type of [<unknown>] buglet.
6948 * WHOIS and IDENTIFY commands call the function
6949 silc_server_command_[whois/identify]_check function even if
6950 we are not router server.
6952 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Added --with-gmp configuration option. If set the GMP
6955 is always compiled in the SILC source tree. If not set then
6956 it is checked whether the system has the GMP3 installed. If
6957 it has then the GMP won't be compiled (the system's headers
6958 and library is used), if it doesn't have it then the GMP is
6959 compiled in the SILC source tree.
6961 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Changed RSA private exponent generation to what PKCS #1
6964 suggests. We try to find the smallest possible d by doing
6965 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6966 not security fix but optimization.
6968 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6970 * Added new config entry [Identity] to fork the server and run
6971 it as specific user and group. A patch from Bostik.
6973 * Imported Dotconf configuration library into lib/dotconf.
6974 This will be used to create the SILC configuration files later.
6975 It will appear in the distsribution after this commit.
6977 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * A big code auditing weekend happening. Auditing code for
6980 obvious mistakes, bugs and errors. Also, removing any code
6983 Removed files for being obsolete:
6985 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6986 inline in the file lib/silcutil/silcbuffer.h)
6988 o lib/silcutil/silcbufutil.c (the header has inline versions)
6990 Changed code to fix possible error conditions:
6992 o The buffer formatting routines now check that the destination
6993 buffer really has enough space to add the data. This applies for
6994 both buffer formatting and unformatting
6995 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6996 unformatting was changed to accomodate following rules:
6997 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6998 sent to the function while XXX_*STRING will not allocate or copy
6999 the data into the buffer. Instead it sets the pointer from the
7000 buffer into the pointer sent as argument (XXX_*STRING used to
7001 require that the pointer must be allocated already). This change
7002 makes this whole thing a bit more consistent and more optimized
7003 (note that the data returned in the unformatting with XXX_*STRING
7004 must not be freed now). The routines return now -1 on error.
7006 o Tried to find all code that use buffer_format and buffer_unformat
7007 and added return value checking to prevent formatting and
7008 especially unformatting errors and possible subsequent fatal
7011 o Changed ske->x and ske->KEY to mallocated pointers in
7012 lib/silcske/silcske.h. Fixed possible data and memory leak.
7014 o Added return value checking to all *_parse* functions. Fixed
7015 many memory leaks as well.
7017 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7018 so that buffer overflows would not happen. All code now also
7019 checks the return value as it can fail.
7021 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7023 * Added reconnection support to server if the normal server looses
7024 its connection to the router (for example if router is rebooted).
7025 The server performs normal reconnection strategy implemented
7026 to the server. Affected file silcd/server.c.
7028 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7030 * Added new packet type SILC_PACKET_SET_MODE that is used to
7031 distribute the information about changed modes (for clients,
7032 channels and clients channel modes) to all routers in the
7033 network. Updated the protocol specification accordingly.
7035 Added functions into silcd/packet_send.c and
7036 silcd/packet_receive.c: silc_server_send_set_mode,
7037 silc_server_set_mode.
7039 Added new files silcmode.[ch] into lib/silccore that implements
7040 the encoding and decoding of Set Mode Payload. Added new type
7041 SilcSetModePayload. Moved the definitions of different modes
7042 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7044 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7046 * Oops, a little mistake in server's connection authentication
7047 protocol. The protocol is not ended with FAILURE but with
7048 SUCCESS if the authentication is Ok. :) Affected file is
7051 * Implemented NICK_CHANGE notify handling in server in the file
7052 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7053 the local clients on the channel. After the changing nickname
7054 in router environment snhould work and the [<unknown>] nickname
7055 should appear no more.
7057 The silc_server_replace_id function that receives the Replace ID
7058 payload now sends the NICK_CHANGE notify type also in the file
7059 silcd/packet_receive.c
7061 * Changed WHOIS and IDENTIFY command to support the maximum amount
7062 of arguments defined in protocol specs (3328 arguments). This
7063 fixed a bug that caused problems when there were more than three
7066 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Added extra parameter, command identifier, to the
7069 silc_client_send_command so that explicit command identifier
7072 Changed that ID list routines uses specific command identifier
7073 when sending WHOIS/IDENTIFY requests to the server so that they
7074 can be identified when the reply comes back.
7076 Affected files lib/silcclient/command.[ch],
7077 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7079 * Added `sender' argument to silc_server_packet_send_to_channel
7080 to indicaet the sender who originally sent the packet to us
7081 that we are now re-sending. Ignored if NULL. Affected file
7082 silcd/packet_send.[ch].
7084 * Added some server statistics support in silcd/server_internal.h
7085 SilcServerStatistics structure and around the server code. Also
7086 send some nice statistics information when client is connecting
7089 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7091 * Fixed channel ID decoding in server's JOIN command reply in
7092 silcd/command_reply.c
7094 * Fixed braodcasting of replace ID payload to not to send it if
7095 we are standalone server in silcd/packet_receive.c.
7097 * Fixed all channel message sending routines to not to send
7098 packets to clients that has router set, since they are routed
7099 separately in the same function earlier. Affects file
7100 silcd/packet_send.c and all channel packet sending functions.
7102 * In USERS reply, res_argv[i] are not allocated, the table
7103 is allocated. Thus changed that free the table, not its
7106 * In server's whois_check and identify_check if the client is
7107 locally connected do not send any WHOIS commands - they are not
7110 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Fixed some minor bugs in client when sending WHOIS command. The
7113 arguments was in wrong order.
7115 * Removed statis function add_to_channel from server in
7116 silcd/command.c that was previously used with the joining but
7119 * Tested USERS command in router environment successfully with two
7120 routers, two servers and two clients.
7122 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Reorganized the USERS command and command reply in client library
7125 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7126 When the command is given by user we register a pending command
7127 callback that will reprocess the command after the reply has been
7128 received from the server. When reprocessing the packet we then
7129 display the information. Thus, the USERS information is displayed
7130 now in the command callback instead of in the command reply
7131 callback. The processing of the command is same as previously
7132 when server has sent the command reply in the JOINing process.
7134 * Added to USERS command in silcd/command_reply.c to join the client,
7135 we didn't use to know about, to the channel after we've created
7136 a client entry for it. Also, for clienet we did know already still
7137 check whether it is on the channel or not and add it if not.
7139 * Removed silc_server_command_join_notify as the function and its
7142 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Changed the client's pending command handling to the same as the
7145 server's pending command handling. It is also now possible to
7146 execute command reply functions from other command reply
7147 function as the function callbacks for commands and command
7148 replies are one and same. The pending commands are not static
7149 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7150 in client connection context. Thus, pending commands are server
7151 connection specific as it is convenient.
7153 Changed the function silc_client_command_pending and
7154 silc_client_command_pending_del and added new function
7155 silc_client_command_pending_check. Removed the
7156 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7159 * Added cmd_ident, current command identifier, to the client
7160 connection context in lib/silcclient/client.h to keep track on
7161 command identifiers used in command sending. Client's command reply
7162 function handling now supports the mandatory command identifiers.
7164 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7165 funtions in client to fully support pending command callbacks.
7167 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7168 as one of the arguments to the application in the command reply
7171 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7172 before first releasing SILC but came back. Now it is removed again
7173 and should come back nomore. The FORWARDED flag was used only
7174 by the JOINing procedure by forwarding the command packet to router.
7175 Now, the JOINing procedure has been changed to more generic (due
7176 to various router environment issues) and FORWARDED is not needed
7177 anymore for anything. The protocol specification is yet to be
7180 Now, removed silc_server_packet_forward from server and the flag
7181 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7183 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Renamed NAMES command to USERS command. The NAMES was named that
7186 due to historical reasons. Now it is renamed. Also, rewrote
7187 parts of the USERS command. The nickname list is not sent anymore
7188 by the server. Only Client ID and mode lists are sent in the USERS
7189 command. Changed this also to the protocol specification.
7191 The client now resolves the names and stuff after it receives
7192 the USERS list from the server when joining to the channel.
7194 * WHOIS and IDENTIFY commands has been changed to support multiple
7195 Client ID's per command. One can now search for multiple users
7196 in the network by sending only one WHOIS or IDENTIFY command.
7197 Changed the code and the protocol specifications.
7199 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7200 uses silc_server_command_whois_parse to parse the request. */
7202 * If normal server, do not parse the WHOIS and IDENTIFY requests
7203 before sending it to the router. Saves some time.
7205 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Fixed JOIN command on client library. Wrong number of arguments
7208 used to crash the client.
7210 * Added silc_server_channel_has_global function to check whether
7211 channel has global users or not.
7213 * Added silc_server_channel_has_local function to check whether channel
7214 has locally connected clients on the channel.
7216 * The silc_server_remove_from_one_channel now checks whether the
7217 channel has global users or not after given client was removed from
7218 the channel. It also checks whether the channel has local clients
7219 on the channel anymore. If it does not have then the channel entry
7220 is removed as it is not needed anymore.
7222 * The silc_server_notify now checks on JOIN notify whether the joining
7223 client is one of locally connected or global. If it is global then
7224 the channel has now global users on the channel and that is marked
7225 to the channel entry. Also, it now saves the global client to
7226 global list who is joining and JOINs it to the channel. This is
7227 for normal server, that is.
7229 Changed silc_server_send_notify_on_channel,
7230 silc_server_packet_relay_to_channel and
7231 silc_server_packet_send_to_channel check if we are normal server
7232 and client has router set (ie. global client) do not send the
7233 message to that client, as it is already routed to our router.
7235 * Implemented LEAVE notify type handling in silc_server_notify
7238 * Tested LEAVE command in router environment successfully. Tested
7239 with two routers, two servers and two clients.
7243 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7245 * Implemented SIGNOFF notify type handling in silc_server_notify
7248 * silc_server_remove_id now removes the client entry from all channels
7249 it has joined and thusly sends SIGNOFF notify type.
7251 * Rewrote the NAMES list generation in server by removing two excess
7252 loops. The lists are created now inside one loop.
7254 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * silc_server_remove_channel_user checks now also global list
7257 for channel and client.
7259 * silc_server_new_channel_user checks now both local and global
7260 list for channel and client. Fixed a bug in client id decoding.
7261 Used to decode wrong buffer.
7263 * silc_server_channel_message checks now both local and global
7264 list for channel entry.
7266 * Tested channel joining (hence JOIN) in router environment
7267 successfully. Tested with two routers, two servers and two
7270 * Tested channel message sending in router environment successfully.
7272 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Added silc_server_save_channel_key into server.[ch] to save the
7275 received channel key in Channel Key payload processing. It is
7276 also used in JOIN command reply handling.
7278 Equivalent function silc_client_save_channel_key added into
7279 client.[ch] into client library.
7281 * Changed JOIN command reply to send information whether the channel
7282 was created or not (is existing already) and the channel key
7283 payload. Changed protocol specs accordingly.
7285 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7286 the request was sent by ID and not by nickname. Crashed on
7289 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7292 now correctly save the received data.
7294 * silc_server_free_sock_user_data now notifies routers in the
7295 network about entities leaving the network.
7297 At the same time implemented functions silc_server_remove_id
7298 and silc_server_send_remove_id to receive and send REMOVE_ID
7299 packets. The packet is used to notify routers in the network
7300 about leaving entities. The ID removed will become invalid in
7303 * Added function silc_idlist_del_server into server. Removes and
7304 free's server entry from ID list.
7306 * silc_server_private_message function now checks, if we are router,
7307 that the destination ID really is valid ID, naturally.
7309 * In router when NEW_ID packet is received (for new client) the
7310 hash of the Client ID is saved in the ID Cache but the
7311 client->nickname is set to NULL, instead of putting the hash
7314 IDENTIFY command now also checks that client->nickname must be
7315 valid. If it is not if will request the data from the server who
7316 owns the client. Added new function
7317 silc_server_command_identify_check.
7319 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7320 to set the command to already allocated Command Payload.
7322 * Tested private message sending in router environment with two
7323 routers, two servers and two clients. Fixed minor bugs and now
7326 * Fixed segfault from client's NAMES command. Used to crash if
7329 * Forwarded packets must not be routed even if it is not destined
7330 to the receiver. Changed server code comply with this.
7332 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Added `require_reverse_mapping' boolean value to ServerParams
7335 structure. If TRUE (not default) the server will require that
7336 the connecting host has fully qualified domain name.
7338 If the reverse mapping is not required and hostname could not be
7339 found the IP address is used as hostname.
7341 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Implemented version string checking to both client and server.
7344 The check is incomplete currently due to the abnormal version
7345 strings used in development version of SILC.
7347 * Changed all command functions in server to use the new
7350 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7352 * Changed char *data to unsigned char *data in ID Cache system to
7353 support binary data as ID Cache data. Changed code to support
7354 binary data in lib/silccore/idcache.c.
7356 * Renamed silc_server_packet_relay_command_reply to
7357 silc_server_command_reply as it is normal packet receiving
7358 function. Rewrote the function to accept command replys for
7359 servers and not only for clients.
7361 * Mark remote router always as registered server if we are connecting
7362 to it. Otherwise, commands sent by the router to us are ignored.
7364 * All ID List find routines now returns the ID Cache Entry pointer
7365 as well if requested.
7367 * WHOIS command works now in router environment, tested with two
7368 routers, two servers and two clients.
7370 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7371 in router environment (as it is almost equivalent to WHOIS) but
7372 hasn't been tested thoroughly. Added new functions:
7374 silc_server_command_identify_parse
7375 silc_server_command_identify_send_reply
7376 silc_server_command_identify_from_client
7377 silc_server_command_identify_from_server
7379 * Disabled route cache adding because adding two different ID's with
7380 same IP replaces the old cache entry thus giving wrong route.
7381 The entry->router->connection is always the fastest route anyway
7382 so route cache may not be needed. Of course, new routes maybe
7383 established after receiving the ID when the entry->router->connection
7384 might not be anymore the most optimal.
7386 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7388 * Add route cache for received ID for fast routing.
7390 * Added silc_server_packet_route to route received packet on router
7391 that is not destined to us.
7393 * Renamed silc_server_get_route to silc_server_route_get.
7395 * Added id_string and id_string_len fields into SilcServer to
7396 include encoded ServerID for fast comparing without excess
7397 encoding of the ID's.
7399 * Cleaned up WHOIS command on server side. Added following static
7402 silc_server_command_whois_parse
7403 silc_server_command_whois_check
7404 silc_server_command_whois_send_reply
7405 silc_server_command_whois_from_client
7406 silc_server_command_whois_from_server
7408 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7409 arguments in command replies. All command functions should be
7410 updated to use this macro.
7412 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7414 * Minor typo fixes on command reply handling on server.
7416 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Added silc_server_command_add_to_channel internal routine to add
7419 the client to the channel after router has created the channel and
7420 sent command reply to the server.
7422 * Added generic silc_server_send_command to send any command from
7425 * Use static buffer with ID rendering instead of duplicating data.
7427 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7429 * Fixed a channel user mode bug when joining to a channel server gave
7430 everybody channel founder rights, oops.
7432 * We mark ourselves as the router of the incoming server connection
7433 if we are router ourselves. This way we can check in some packet
7434 sending functions whether it is locally connected server. For
7435 incoming router connections we put NULL.
7437 * For router sending packets locally means now always sending the
7438 packet cell wide; to local clients and local servers. For normal
7439 server sending packet locally means sending it to only local
7442 * Fixed the JOIN command to really work in router environment. If the
7443 channel is created it is always created by the router. Router is
7444 also responsible of making the initial joining to the channel,
7445 sending JOIN notify to the sending server and distributing
7446 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7447 does not exist server doesn't do anything else but forward the
7448 command to the router which performs everything.
7450 * Added silc_server_send_channel_key function to send the Channel Key
7453 * Added silc_server_create_channel_key to create new channel key. The
7454 channel key is now re-generated everytime someone joins or leaves
7455 a channel, as protocol dictates. Note: channel->key_len is the
7458 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7460 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7461 packet_receive.[ch] to separate packet sending and receiving
7462 routines. The server.[ch] now includes everything else including
7463 actual packet processing (writing and reading data) and other
7466 Renamed silc_server_private_message_send_internal to
7467 silc_server_send_private_message. The routine is still though
7468 used only to relay private messages as server does not send
7469 private messages itself.
7471 Renamed silc_server_new_channel to silc_server_create_new_channel
7472 and added new function sicl_server_new_channel that handles the
7473 incoming New Channel packet. Added also new sending function
7474 silc_server_send_new_channel to send New Channel Payload.
7476 * Added new function silc_server_notify to process incoming notify
7477 packet to the server/router. Server may then relay the notify
7478 to clients if needed.
7480 * Added new function silc_server_new_channel_user to process incoming
7481 New Channel User packet. Router will redistribute the packet and
7482 send JOIN notify to its local clients and locally connected servers
7483 if needed. Normal server will send JOIN notify to its local client
7484 on same channel when received this packet. Added also corresponding
7485 sending function silc_server_send_new_channel_user to sent the
7488 * Added boolean route argument to send_notif_to_channel and
7489 packet_send_to_channel functions to attempt to route the packet
7490 if it is TRUE and send only locally if it is FALSE.
7492 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7494 * silc_server_replace_id now broadcasts the received replace ID
7495 packet if it is not broadcast packet already. The router must
7496 broadcast to inform other routers about changed ID.
7498 * Added backpointer to server's router into SilcServer context in
7499 silcd/server_internal.h.
7501 * Fixed silc_server_packet_broadcast to send correct broadcast
7504 * The channel key is now distributed to the local client as soon
7505 as it is received from the router (in router environment) so that
7506 no other packet may be sent for the channel until client has
7509 * silc_server_remove_channel_user now broadcasts the received
7510 Remove Channel User packet if it is not broadcast packet already.
7511 The router must broadcast to inform other routers about removed
7514 * Added users field into SilcPacketContext that is a reference count
7515 of the context. One can increase the reference count by calling
7516 silc_packet_context_dup which is now changed to just increase the
7517 reference count instead of duplicating the data. The reference
7518 count is decresed by calling silc_packet_context_free that will
7519 free the data after the reference count hits zero.
7521 For now on the packet context and everything allocated into it
7522 (including the raw packet from network) must be freed by calling
7523 the new silc_packet_context_free function. Added also new function
7524 silc_packet_context_alloc that must be used now to allocate the
7525 context. This also means that if a routine is asynchronous from
7526 silc_[client/server]_packet_parse_type the packet context must
7527 be duplicated by calling silc_packet_context_dup. Otherwise it
7528 gets free'd after silc_[client/server]_packet_parse_type returns.
7529 Also, one must remember that if packet is duplicated then its
7530 reference count must be decresed by calling the free function as
7531 many times as it was duplicated.
7533 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7534 from both client and server.
7536 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Made joining to a channel working in router environment.
7540 * Cleaned up JOIN command on server side and create function
7541 silc_server_command_join_channel internal routine to make the
7544 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7546 * Changed silc_command_pending list to SilcDList. Also, added
7547 `ident' field to SilcServerCommandPending structure to identify
7548 the reply and to call correct callback.
7550 Added silc_server_command_pending_check function to replace the
7551 corresnponding macro. The silc_command_pending list is not
7554 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7555 to set identifier to previously allocated Command Payload. It
7556 is used to set identifier for command when resending Command
7559 * Added silc_command_payload_encode_payload to encode Command
7560 Payload buffer from SilcCommandPayload structure.
7562 * Added silc_argument_payload_encode_payload to encode Argument
7563 payload buffer from SilcArgumentPayload structure.
7565 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7567 * Changed WHOIS command to support router connection on server side.
7568 The whois request is always sent to router unless the server is
7569 standalone server. After server has received the reply from the
7570 router will it send the reply to the client.
7572 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7573 broadcast received broadcast packet. The function is used only
7574 by router. The broadcast packet is always sent to the router's
7577 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7578 render given ID to printable string, for log files for example.
7580 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Made basic router to router connections working. At least they
7583 can now connect to each other but nothing really works the way
7584 they are supposed - yet.
7586 * Added new initiator token to RouterConnection configuration
7587 file in silcd/serverconfig.[ch]. It is used to tell whether we
7588 are the initiator to the remote router or whether we'll expect
7589 the other end to connect.
7591 * Moved registering of listener task to silc_server_init, hence
7592 the server starts listenning as soon as it is run, even if it
7593 does not have connections to other routers. Let's see how well
7596 * Changed default connection retry timeouts for more suitable in
7599 * Removed cipher and such arguments from silc_idlist_add_client
7600 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7601 Added new function silc_idlist_add_data to add the keys and stuff
7604 * Added SilcIDListData structure and added it to SilcClientEntry
7605 and SilcServerEntry as their first field in the structure. This
7606 way we can explicitly cast the ID entries to the SilcIDListData
7607 structure and get common data for the entries. In past, we had
7608 to first check what type of connection it is and then cast it to
7609 correct ID entry type. Now, we can directly cast the opaque
7610 pointer to the SilcIDListData (no matter what ID entry it actually
7611 is) and get the data needed.
7613 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7616 in some circumstances even if threre were timeout tasks, though not
7617 IO tasks, but tasks anyway. Now fixed.
7619 * Defined SilcServerConnection structure to hold connection specific
7620 stuff about directly connected servers and routers. The definition
7621 is currently in silcd/server_internal.h. I thought about having
7622 a bit more important role fro this struct but for now it is used
7623 only when connecting to other server (or router actually).
7625 * Added connecting retry support in server when connecting to
7626 router(s). The retry feature implement exponential backoff
7627 algorithm. Also, added SilcServerParams structure to hold default
7628 parameters for server. For now, it include these retry settings
7629 and are hard coded. After server is moded to be as Silc Server
7630 Library this structure will be more important.
7632 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Changed client librarys channel->clients table to SilcList and
7635 changed code accordingly.
7637 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Changed client's channel table to SilcList and changed code
7640 accordingly. Also changed SilcChannelClientEntry to include back-
7641 pointer to the channel so that client entry can use that structure
7642 as list as well and we have fast cross-reference to the channel.
7643 This change dramatically decreased the complexity of channel
7644 handling with client entry and vice versa (removed one extra
7645 loop when searching for channel entry from many functions).
7647 * Changed server->sim from table to SilcDList and changed code
7650 * NAMES command can now be used from user interface. It will show
7651 the user list on the channel, neatly.
7653 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7654 Code now saves realname of the user if it becomes available.
7656 * Renamed configure.in to configure.in.pre and made ./prepare
7657 script to automatically add correct version string to
7658 configure.in which it creates from configure.in.pre.
7660 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * NAMES command reply now shows users mode with the nickname when
7665 * Moved silc_client_ch[u]mode[_char] functions from
7666 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7667 place sucks, they are utility functions and should be in some
7670 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7672 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7675 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7679 * Added TRQ (efficient deque and list library) into lib/trq. This is
7680 a very good list library that is currently used in the SILC. Defined
7681 SilcList API over the library because I didn't like the API very
7682 much. See lib/trq/silclist.h for the API and examples of how to
7683 use the API. Fixed various places in the code to use the new
7684 SilcList API. The SilcList is meant for lists that has a structure
7685 already defined as a list. It is not suitable to add just some
7686 context to the list (in TRQ, the context is the list actually).
7688 So, I defined SilcDList that can be used for the purpose where
7689 predefined list structure does not exit. This can be used as
7690 such list. Now some context just can be added to the SilcDList.
7691 Currently this list is not used in the SILC just yet, though there
7692 are a lot places where this can replace dynamically allocated
7693 tables and I will fix these places, later, to use SilcDList.
7694 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7695 and use TRQ internally).
7697 Also fixed some annoying warning messages that the original TRQ
7698 code generated. Also minor changes to TRQ's Makefile.in.
7700 * Added support for querying by Client ID to both WHOIS and
7701 IDENTIFY commands into server, as required by the protocol.
7703 * Removed method function pointers from SilcBuffer structure. They
7704 weren't used to anything and just increased the context size for
7705 no good reason. This change also made silc_buffer_alloc and
7706 silc_buffer_free functions inline functions.
7708 * Disabled command flooding detection support until it's fixed so
7709 that it accepts commands in but does not execute them more than once
7712 * Added silc_net_localhost(), to return local hostname, into
7713 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7714 that must be initialized before calling silc_client_init.
7716 * Added new function: silc_server_send_notify_on_channels to send
7717 notify messages to all channels client has joined. It is assured
7718 that the message is sent only once per client.
7720 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7721 lib/silcutil/silcutil.[ch] as silc_format function. The new
7722 function is generic and is used by server as well, not only by
7723 the logging routines.
7725 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7726 the provided version string was not acceptable. Added new function:
7727 silc_ske_check_version into lib/silcske/silcske.h. The function
7728 must be implemented by the application (client or server) and it
7729 does not reside in the SKE library. The function checks the version
7730 string remote end sent.
7732 * Added back pointers (to opaque context and to SilcSocketConnection)
7733 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7735 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7736 duplicate packet context structure.
7738 * Changed `notify' client operation to send same arguments as client
7739 receives from server except for ID's. ID's are mapped to correct
7740 ID entry and that is returned. Also, if channel entry is not sent
7741 by server but the notify is for channel the channel entry is sent
7742 to application (otherwise application doesn't know that it is for
7743 channel (library gets it from packet's Destination ID)).
7745 * Added silc_client_remove_from_channels into client library to
7746 remove a client from all channels it has joined to. Used when
7747 received SIGNOFF notify from server. Added also new function
7748 silc_client_replace_from_channels to replace old ID entry with
7749 new ID entry on all channels. Used when received NICK_CHANGE
7752 * Fixed ID Cache list handling in silc_idlist_get_client in
7753 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7754 to get (or query) client by ID.
7756 * Updated TODO list.
7758 * Added connection authentication status message defined by the
7759 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7760 support for these into the code in client and server side.
7762 * Added generic function silc_client_send_command to send any command
7763 with variable argument list. Application should use this function
7764 to send commands if the command functions provided by the library
7765 does not suite for the application's user interface needs.
7767 * Added new `failure' client operation. Application is notified about
7768 received failure packet if client is executing a protocol. In this
7769 case the protocol's execution has failed.
7771 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7772 is required by the protocol.
7774 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7775 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7778 * Added status flag to SilcSKE object to indicate realtime status
7779 of the SKE protocol.
7781 * Application receives now exactly same command reply arguments as
7782 the library receives from server. However, if ID is received the
7783 corresponding ID entry is returned to the application (eg. Client
7784 ID is mapped to correct SilcClientEntry entry and that is returned).
7785 Changed command_reply client operation due to this change.
7787 * Changed all ID's in commands and in command replys as ID Payloads.
7788 Change affected both client and server side codes.
7790 All ID's sent in SILC network (with execption of ID's in SILC
7791 Packet header) are sent in ID Payload to support variable length
7794 * Server now notifies nick changes and notifies all clients on
7795 the channels about the new nickname (about the new Client ID,
7798 * Implemented CMODE command to change channel modes. Supports all
7799 channel modes defined by the protocol specs except ban and invite
7800 lists. (Also, private channel key mode is supported but support for
7801 setting private channel key in client is missing, thus, this mode
7802 has no effect on client side (except that server requires that the
7803 client uses private channel key and normal channel traffic does not
7806 Also, invite mode works per se, but INVITE command does not work
7807 yet correctly, so you can set channel as invite only channel but
7808 inviting clients to the channel does not work (it is yet to be
7809 thought what's the best way to do it).
7811 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7812 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7813 Implemented CUMODE command to change user's mode on the channel.
7814 Supports all modes defined by the protocol specs.
7816 * Added NAMES command reply to return users modes on the channel.
7818 * Removed unnecessary and slow ciphers from lib/silccrypt.
7820 * Set SO_KEEPALIVE option to connection sockets by default.
7822 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7824 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7825 redefined the Notify Payload into protocol specs.
7827 * Added silc_id_payload_parse_id to get ID directly from raw
7830 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7833 accept searching by Client ID as well.
7835 * Added support for LEAVE and SIGNOFF notify types in client library.
7837 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7838 to parse ID Payload from raw data.
7840 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7842 * Added flags parameter into silc_ske_assemble_security_properties
7843 function in lib/silcske/silcske.[ch].
7845 * Changed notify client operation to fit better for notify messages
7846 sent by server. The notify payload received from server is now
7847 passed to the application (after parsing it to SilcNotifyPayload).
7848 It is application's responsibility to retrieve the arguments
7849 from the payload and show the message the way it wants. The message
7850 sent by server is implementation specific.
7852 * Changed public keys to comply with the protocol specification.
7853 Old public keys are not supported anymore and are not compatible.
7855 * Removed nickname from Channel Payload as the latest draft removed
7856 it. The client must resolve the nickname from the NAMES command
7857 reply received when it joined the channel.
7859 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7861 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Fixed some errors in protocol specification drafts.
7865 * Created lib/silccore/silcnotify.c to implement Notify Payload
7866 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7867 generic payloads described by protocol specifications. The file
7868 includes implementations for ID Payload and Argument Payload.
7870 * Changed Command Payload implementation to use the new Argument
7871 Payload. Changed command_xxxx_payload to command_payload_xxxx
7872 to comply with SILC coding conventions.
7874 * Added suppport for Argument Payload handling in Notify Payload
7875 implementation as protocol requires it. Added the new support
7876 into server and client lib as well.
7878 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Added support for multiple nicknames on same channel. [n] is
7881 added locally to the nickname if there are more than one same
7882 nicknames on the channel.
7884 * Server now sends all nicknames that matched WHOIS request.
7885 Client also shows the list received from server.
7887 * Added TOPIC command to client side. User can now set and show
7888 current topic on channel.
7890 * Added MOTD command to client and server. Also, server sends the
7891 motd when client connects to the server.
7893 * Changed version strings to comply ISO 8601.
7895 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Fixed protocol error handling in client library. It should now
7898 cope even if the SKE fails for some reason.
7900 * Made new protocol specification drafts for submitting to IETF.
7902 * Implemented TOPIC command to server in silcd/command.c.
7904 * Added two new notify types into lib/silccore/silcnotify.h:
7905 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7906 notify nickname change and topic setting/change on a channel.
7908 * API change of command_reply operation in client library. The
7909 application gets now the status type received from server as well.
7911 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7913 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7915 * Cras fixed and optimized the packet handling even further and
7916 it should work now. Minor change to the prototype of function
7917 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7919 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7921 * Added new function into lib/silcutil/silcschedule.[ch]:
7922 silc_schedule_with_fd to select() a specified fd. The function
7923 returns after timeout expires or data arrives or goes. The
7924 function is used by packet routines to wait that all data is
7925 received from network.
7927 * Fixed data reading from network in lib/silccore/silcpacket.c.
7928 The code now assures that all data is read from the fd and then
7929 continues packet processing. This was a bug fix since the code
7930 used to drop some data in some circumstances.
7932 * Added new function into lib/silcclient/client.[ch]:
7933 silc_client_start_key_exchange to start key exchange after
7934 connection has been established to server. The code internally
7935 now uses this funtion but its main purpose was to provide it
7936 for applications that perform their own connecting. After
7937 application has created a connection it merely calls this
7938 function to start the key exchange between client and server.
7939 The library takes care of everything else after that.
7941 Updated also lib/silcclient/README to explain the usage of
7944 * Do not send to application information that connection has
7945 been established. Application gets notified it by connect
7948 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7950 * Applied cras's patch to add silc_schedule_one function. The
7951 function runs scheduler once and returns.
7953 * Fixed the scheduler after cras messed it up. The timeout
7954 handling works now as it's supposed to work.
7956 * Added into lib/silccore/ silcnotify.h to include notify
7957 message types support. Changed silc_server_send_notify*
7958 functions, in server.[ch], to support those new notify types.
7959 Added the support for the notify types into client library,
7960 as well. Added new notify client operation into ops.h in
7963 * Changed silc_server_packet_send_to_channel to send normal
7964 packets instead of just channel message packets. The function
7965 is now used to send the notify packets to channels. It is not
7966 used to send channel message packets anymore, as server never
7969 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7970 va_arg()s as it seems to require it nowadays. I guess, if SILC
7971 is compiled with older va_arg() the new code should work anyway.
7973 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7975 * Splitted core library. Core library (lib/silccore) includes
7976 now only SILC protocol specific core (and common) components.
7977 Created new utility library (lib/silcutil) that includes more
7978 generic purpose stuff. The stuff for util library was taken
7979 from the old core library. This was minor and easy split.
7981 * Created SILC Client Library (lib/silcclient) that includes
7982 implementation of the SILC client without user interface. This
7983 was major move from silc/ directory. The code has been changed
7984 so that it is transparent towards the user interface. The
7985 silc/ directory includes now the same user interface as before
7986 and it uses the new client library. Read lib/silcclient/README.
7987 Basicly, the client library performs everything else related
7988 to SILC except user interface handling. Also, configuration
7989 files are considered to be part of user interface and library
7990 does not handle them.
7992 This change also changed a lot of structures, function naming etc.
7993 Most important change was that SilcClientWindow object was
7994 renamed to SilcClientConnection in the client library. Created
7995 also new file lib/silcclient/ops.h. Also added new files
7996 silc/local_command.[ch] and silc/client_ops.[ch].
7998 All these changes were made to make it easier for user interface
7999 designers to create what ever user interface for the SILC client
8002 It is also expected that the server will be moved to lib
8003 directory as well and SILC Server Library will be created;
8004 sometimes in the future.
8006 * Removed Local commands from lib/silccore/silccommand.h as
8007 they are application specific and new client library does not
8008 handle any of those anymore.
8010 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8011 old client implementation in silc/.
8013 * Added support for callback functions in SILC_LOG_* macros.
8014 Application can now set its own callbacks that will be called
8015 instead of using the default functions that will always print
8016 the debug messages to stderr (or stdout). Also, debugging can
8017 now be disabled by setting silc_debug to FALSE and re-enabled by
8018 setting it to TRUE. Note, that logging will still work even
8019 if debugging is disabled.
8021 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8022 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8023 silc_log_reset_debug_callbacks.
8025 * To enable debugging in silc client one must give now -d
8026 option on command line.
8028 * Changed silc_schedule_init to automatically allocate task queues
8029 if they are not allocated before calling it.
8031 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8033 * Added GMP 3.1 into math library.
8035 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8037 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8038 a channel in SILC network. The packet is used by servers and
8039 routers to notify other routers that user has left a channel.
8040 This little feature was missing until now. Added the feature
8041 to protocol specification as well.
8043 Added functions: silc_server_send_remove_channel_user and
8044 silc_server_remove_channel_user into server.[ch].
8046 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8047 lib/silccore/silcpacket.h. However, they are not implemented
8050 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8052 * Fixed joining to a channel and sending channel messages
8053 between server and router. The channel message sending should
8054 now work inside a cell.
8056 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8058 * Fixed the private message sending between server and router.
8059 The private message sending should now work inside a cell.
8061 * Added silc_server_replace_id into server.[ch] to replace
8062 existing ID in the SILC network.
8064 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8065 and silc_idlist_replace_server_id into idlist.[ch] in server.
8067 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Fixed the server to server connections. Server can again now
8070 connect to router. Router to router connections probably does
8073 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8075 * Added dynamic protocol registering support. Now protocols can
8076 registered and unregistered on the fly. Patch by cras.
8078 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Added lib/contrib directory to hold routines that some platforms
8081 don't have but are needed by SILC.
8083 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8084 into lin/contrib to provide getopt() and getopt_long() for
8085 those who don't have it.
8087 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8089 * Added AWAY command to client. When away message is set and
8090 client receives a private message packet the client automatically
8091 replies to the sender with the away message.
8093 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8094 bug seemed to be the cause of recent problems when compiling
8097 * Added version detection support to SKE protocol specification
8098 and added the new changes to the SKE implementation as well.
8099 There were other minor changes in the SKE protocol as well.
8101 Many changes in lib/silcske/silcske.[ch] and in
8102 lib/silcske/payload.[ch].
8104 * Added ^U functionality, clear input line. Patch from cras.
8106 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8108 * Mainly small bugfixes on core library. Fixed some debugging
8109 logging and buffer overflow in silclog.c.
8111 * Updated config.sub and config.guess on the distribution tree.
8113 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Added command lagging support in server. Client may execute
8116 commands now only once in two seconds.
8118 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8120 * Optimized packet reception. MAC computation and checking is now
8121 also more optimized. A lot previously duplicated code is now
8122 used as generic by both client and server.
8124 * Fixed key pair generation in clientutil.c
8126 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8128 * Added into lib/silccore/silcbufutil.[ch] new function;
8129 silc_buffer_realloc.
8131 * Moved generic packet sending/encryption functions to
8132 lib/silccore/silcpacket.[ch] from client and server. Some
8133 rewriting of the functions.
8135 * Moved all generic packet reception/decryption functions to
8136 lib/silccore/silcpacket.[ch] from client and server. The
8137 packet processing is now much cleaner in both client and server.
8138 These were major changes in both client and server.
8140 * Created many common functions in server to do packet sending.
8141 Previously code were duplicated a lot, this has been removed
8144 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8146 * Rewrote major parts of the ID cache system. Don't know
8147 whether it is better now or not but at least the API is more
8150 * Major rewrite on ID cache stuff on client because of the ID
8151 cache API changes. Added idlist.c to client.
8153 * Also major rewrite on ID cache stuff on server as well.
8154 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8155 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8156 in hand, instead they are all put into the ID cache system now.
8157 All server_idlist_* routines uses ID cache now instead of
8158 traversing its own lists (those lists does not exist anymore).
8159 SilcIDList though still exists. Also, SilcXXXEntry's are
8162 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8164 * Finally made the SKE implementation compliant to the protocol
8165 specification. All mp integers are now binary encoded as
8166 opposed being HEX encoded.
8168 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8171 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8172 functions: silc_[encode/decode]_pem. Also added function
8173 silc_encode_pem_file to PEM encode with newlines ('\n') for
8176 * SILC public keys are now encoded either PEM or binary. Same
8177 option is for private keys as well. By default private keys
8178 are binary encoded and public keys PEM encoded. Silly HEX
8179 encoding were removed.
8181 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8182 function to create fingerprints.
8184 * Fixed a bug in SHA1; does not change the original data anymore.
8186 * Partly implemented INFO command on client and server side.
8187 Fixed CLEAR command. Changes to SERVER command; show current
8188 server(s) when giving command without arguments. Added
8189 VERSION command to client.
8191 * Added check to server that unregistered connections cannot
8192 execute commands (unless it is specificly allowed).
8194 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Fixed screen refresh.
8198 * Fixed channel joining bug from client. On some circumstances
8199 client tried to join to a channel it had already joined.
8201 * Added public key verification process into client's protocol.c.
8202 The client now verifies the public key from user and saves
8203 it into ~./silc/serverkeys/ directory.
8205 Added into: clientutil.[ch]: silc_client_verify_server_key.
8207 * Changed SKE protocol's silc_ske_initiator_finish function
8208 to accept callback function that verifies the received public
8209 key. Removed old silc_ske_verify_public_key function.
8211 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8214 silc_pkcs_private_key[_data]_set.
8216 * Made the password and public authentication more cleaner in
8217 server's protocol.c.
8219 * Removed historic and obsolete protocol `channel_auth' from
8220 both client and server.
8222 * Removed wrong way of sending command status messages from
8223 server to client in server's command.c. The old way violated
8224 protocol specification.
8226 Changes to silccore/silccommand.[ch]: removed
8227 silc_command_encode_status_payload -> not needed anymore,
8228 changed silc_command_encode_payload_va to accept extra
8229 argument on variable argument list. The argument type must
8230 now be provided to the function. Also, added new function:
8231 silc_command_encode_reply_payload_va which is same as
8232 normal command_encode_payload_va except command status type
8233 is provided as extra argument.
8235 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8237 * Added ~./silc directory handling. The directory includes the
8238 public and private keys for the client.
8240 Added silc_client_check_silc_dir, silc_client_create_identifier
8241 and silc_client_load_keys.
8243 * Implemented SILC protocol compliant public key. Added public
8244 and private key saving to and loading from files.
8246 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8247 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8248 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8249 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8250 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8252 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8253 silc_pkcs_load_[public/private]_key.
8255 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8257 * Added silc_server_get_route (route.[ch]) to get connection
8258 data for the fastest route for given ID.
8260 * Implemented INVITE command on client and server. The command
8261 were re-defined in the SILC Protocol Specification and the
8262 implementation now complies with the specification.
8264 * Implemented PING command on client and server.
8266 * Implemented NAMES command on client and server. The server side
8267 supports currently only normal server not router server yet.
8268 Some changes to NAMES definition in SILC protocol specification.
8270 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8272 * Implemented LEAVE command on client and server.
8274 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8275 again. This change was made to the protocol as well. Server
8276 should not violate the protocol specification anymore.
8278 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8281 was tested. SOCKS4 was not but should work anyway.
