260 * Redefined the Status Payload to include now two 8 bit fields,
261 instead of one 16 bit field. This now makes it possible to
262 send list of errors. Updated the protocol specs and the code
263 in core library, client library and server. Protocol TODO #1.
264 Affected files are lib/silccore/silccommand.[ch],
265 lib/silcclient/command_reply.[ch], silcd/command.c,

301 statistics from router. Updated the protocol specs and
302 implemented it to the server. Protocol TODO #16.
303 Affected files are lib/silccore/silccommand, silcd/command.[ch],
304 silcd/command_reply.[ch].
306 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
308 * The LIST command reply in client libary now adds new channel
309 entry if the returned channel doesn't exist yet in cache,
310 and returns the channel entry to the application in the
311 command_reply client operation. Affected file is
312 lib/silcclient/command_reply.c.
314 * Changed the channel message payload's MAC generation to
315 include the IV in the MAC as well. This way all relevant
316 parts of the channel message payload are authenticated also
317 with the channel message MAC (and not only by packet MAC).
318 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
319 Affected file is lib/silccore/silcchannel.c.
321 * Fixed the SKE to save the remote version, since the
322 silc_ske_parse_version mistakenly checked wrong version,
323 after it replaced the start payload. Affected files are

347 need the SilcSocketConnection which should not be visible
348 to application. Affected files are lib/silcclient/client.c
349 and lib/silcclient/silcclient.h.
351 * Rewrote the text for Private Message Key Payload in the
352 protocol specification. Protocol TODO #11.

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

478 * Changed the silc_get_username and silc_get_real_name to
479 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
481 * Fixed the Irssi SILC Client to use the silc_get_username and
482 silc_get_real_name insted of glib routines since the glib
483 routines only corrupt stack. Fixes the Irssi SILC to work in
484 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
486 * Fixed the Irssi to not use g_get_home_dir since it crashes

500 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
502 * And yet again reverted back the config thing since Johnny
503 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
506 * Fixed memory leaks from config object. Affected files are
507 silcd/serverconfig.[ch].
509 * Added support for adding new connections to the server in rehash.
510 After rehash they take effect.
512 Added support for changing the maximum allowed connections in
513 rehash. The number can grow but going smaller is not supported.
515 Added function silc_server_num_sockets_by_remote to the
516 silcd/server_util.[ch].
518 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
520 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
522 * Added preliminary checking during config parsing for a valid
523 public/private key and removed further checks in the code.
524 Affected files are silcd/serverconfig.[ch], server.c.
526 * Moved functions silc_server_drop() and silc_server_daemonise()
527 from server.c to silcd.c since they are stricly related to
528 the application activity.
530 * Reverted a small part of the automatic ref/unref since
531 it caused a double unref in some situations. Affected
532 files are silcd/silcd.[ch], server.c, serverconfig.c.
534 * Added some .cvsignore files in the lib directory.
536 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
538 * Fixed silc_net_gethostbyaddr to correctly resolve by
539 address. Affected file lib/silcutil/silcnet.c.
541 * Fixed the notify relaying to client. The HMAC to be used
542 with relayed packets ws wrong and caused decryption failure
543 at the client end. Affected file is silcd/packet_receive.c.
545 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
547 * Created new branch silc_protocol_1_0_branch.
549 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
551 * Changed the silc_server_config_* routines to be SilcServer
552 independent. They are now officially application specific code
553 and not part of generic server implementation. Affected files
554 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
556 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
558 * Added automatic referencing of config context in the
559 silc_server_config_alloc, and automatic unreferencing in the
560 silc_server_config_destroy. Affected files are
561 silcd/serverconfig.[ch], silcd/silcd.c.
563 * Fixed the silc_log_quick handling in the logging routines.
564 It didn't log quickly when it was TRUE. Affected file is
565 lib/silcutil/silclog.c. Also the flush delay was set even
566 if it was 0 in config file. Affected file is
567 silcd/serverconfig.c.
569 * Added support for changing key pair of the server in rehash.
570 Affected file silcd/server.c.
572 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
574 * Fixed the TOPIC_SET notify to not cras. It changed the topic
575 too early, before getting the channel entry. Affected file
576 is silcd/packet_receive.c.
578 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
580 * Added functions silc_server_config_[ref/unref], these are used
581 to prevent that the config object is destroyed.
583 No longer directly affect global variables silc_log_quick and
584 silc_log_delay, they are first cached inside the config object
585 and then applied with silc_server_config_setlogfiles().
587 silc_server_config_set_defaults() is now internal to
588 serverconfig.c, there are no reasons to show this internal stuff
591 Affected files are silcd/serverconfig.[ch].
593 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
594 fprintf's to stderr, since some code may be executed again after
595 the server went into the background. Affected files are
598 * Added rehash support. Added function silc_server_rehash() that
599 will perform all the basic tasks of the rehashing procedure.
601 * Added command line option `-x, --hexdump'. This will enable the
602 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
603 The option `--hexdump' implies `--debug'.
605 * Fixed a bad bug in the logging APIs (silcutil library) where
606 the application would crash after calling silc_log_reset_all().
608 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Fixed the KICKED notify handling in client library to
611 correctly remove the channel and all entries from the
612 channel when I was kicked. This bug crashed the client.
614 Fixed yet another but in KICKED notify handling to remove
615 the kicked client correctly from the channel.
617 Affected file is lib/silcclient/client_notify.c.
619 * Fixed a minor bug in looking up correct client entry
620 in KICKED notify in server. Affected file is
621 silcd/packet_receive.c.
623 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
624 sources correctly to distribution. Fixes --with-gmp option.
626 * Removed the manual rehashing from ID Cache, and changed it
627 to use the SILC Hash Table's auto rehash feature. Affected
628 file is lib/silccore/silcidcache.c.
630 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
632 * Fixed a bug in the silc_client_nickname_format function that
633 handles the multiple same nickname formatting. Two clients
634 with same nickname caused problems after the first one left
635 and rejoined. It didn't format the nickname correctly.
636 Affected file is lib/silcclient/idlist.c.
638 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
640 * Don't change the topic if olod topic is same as new one.
641 Affected file is silcd/packet_receive.c.
643 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
645 * Added cross-reference support to the SILC Documentation
646 generator. All types across all HTML files are now cross-
647 referenced. Affected files util/robodoc/generator.c and
648 scripts/silcdoc/silcdoc.
650 * Added file lib/silcutil/silctypes.h to include all the
651 arithmetic type definitions and some macros. Removed
652 includes/bitmove.h and moved macros to silctypes.h.
654 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
658 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Added `type' argument to silc_id_payload_parse_id function which
661 now returns the type of the ID to the sent pointer. Affected
662 file is lib/silccore/silcid.[ch].
664 * Added check for CMODE_CHANGE notify type that mode change is
665 allowed by the sender. Affected file silcd/packet_receive.c.
667 * Added check for CUMODE_CHANGE notify type that mode change is
668 allowed by the sender. Affected file silcd/packet_receive.c.
669 Added the ID type as CUMODE_CHANGE notify type as argument
670 to the `notify' client operation. Affected files are
671 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
673 * Added function silc_client_add_server to the client library.
674 Added support for resolving also channel and server info when
675 received unknown entity in notify packet. Affected files are
676 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
678 * Added function silc_command_get_status to return the command
679 status from the command reply's argument payload. Affected files
680 are lib/silccore/silccommand.[ch].
682 * Added check for KICKED notify type that the kicking is
683 allowed by the client. Affected file silcd/packet_receive.c.
685 * Created function silc_get_input which can be used to get input
686 (echo on or off) from user on command line. Affected files are
687 lib/silcutil/silcutil.[ch].
689 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
691 * Optimized silc_server_packet_relay_to_channel function.
692 Added new function silc_channel_message_payload_encrypt which
693 can be called directly if channel message payload needs to
694 be encrypted and is already encoded (no need to call _encode
695 function). Packet relaying is now done by router without any
696 extra memory allocations. Affected files are
697 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
700 * Fixed the INVITE notify handling. It took wrong arguments
701 as invite list and invite delete. Affected file is
702 silcd/packet_receive.c.
704 * Added check for TOPIC_SET notify type that the topic change is
705 allowed by the client. Affected file silcd/packet_receive.c.
707 * Added check for INVITE notify type that inviting is allowed by
708 the client. Affected file silcd/packet_receive.c.
710 * Changed the silc_server_client_on_channel to return the
711 SilcChannelClientEntry as well. Moved the function
712 silc_server_check_cmode_rights to server_util.[ch].
713 Affected files are silcd/server_util.[ch], silcd/command.c.
715 * Added function silc_server_check_umode_rights to check whether
716 changing client's user mode is allowed. Added check for
717 UMODE_CHANGE notify type that the umode change is allowed
718 by the client. Affected files are silcd/server_util.[ch],
719 silcd/packet_receive.c and silcd/command.c.
721 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
723 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
724 ID length. It ignored that ID can be IPv6 based as well.
725 Affected file lib/silccore/silcpacket.h.
727 * Fixed the silc_id_id2str and silc_id_str2id to take the
728 IPv6 address offset's into consideration. Affecte file is
729 lib/silccore/silcid.c.
731 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
733 * Fixed the internal Unix scheduler functions to check for
734 NULL context they may receive. The affected file is
735 lib/silcutil/unix/silcunixschedule.c.
737 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
739 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
740 can specify different directory with --home command line
741 parameter. Affected files irssi/src/silc/core/client_ops.c,
744 * SILC-specific commands aren't now executed if the active server
745 isn't of SILC-type, so there won't be problems with having
746 IRC and SILC protocol support in same client. Affected files
747 irssi/src/silc/core/silc-channels.c, silc-servers.c,
750 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
752 * Improved the signal support in SILC Schedule. Added new
753 function silc_schedule_signal_call which is used by application
754 to mark a signal to be called. It is now safe to perform
755 any kind of tasks in signal callbacks since it is guaranteed
756 that the application specified signal callback is called
757 after the signal is over. Affected files are
758 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
760 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
762 * Added `name' field to SilcChannelPrivateKey to represent
763 application given name for the key. Moved also the context from
764 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
765 Added the `name' argument also to the function
766 silc_client_add_channel_private_key.
768 Added function silc_client_current_channel_private_key to set the
769 current channel private key in use.
771 Added "change" command to KEY command which can be used to change
772 the current channel private key. Bound the command also to
775 Also affected files lib/silcclient/client_channel.c,
776 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
778 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
780 * Added silc_rng_get_byte_fast function in to the
781 lib/silccrypt/silcrng.[ch].
783 * Changed the interface of silc_packet_assemble and the
784 silc_packet_send_prepare. If silc_packet_assmble is now
785 called the application does not call silc_packet_send_prepare
786 because the library will call it automatically. These
787 interfaces now also return a reference to the outgoing buffer
788 which includes the assembled packet, which the application can
789 use to encrypt the packet.
791 Affected files are lib/silccore/silcpacket.[ch],
792 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
793 silcd/packet_send.c, server_backup.c and packet_receive.c.
795 * Fixed a packet sending bug on very high load, where outgoing
796 packet queue wasn't handled correctly and packets got corrupted.
797 Affected files are lib/silcutil/*/silc*sockconn.c,
798 lib/silcclient/client.c and silcd/server.c.
800 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
802 * Added macro SILC_PACKET_DATALEN which can be used during
803 packet assembling to check whether the data to be added to
804 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
805 len is truncated until it fits it.
807 Added checks for maximum length of channel message payload and
808 private message payload also.
810 Added checks for maximum packet length in server and in
813 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
814 lib/silcclient/client.c, lib/silccore/silcchannel.c and
815 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
816 lib/silcclient/client_prvmsg.c.
818 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
820 * Added silc_server_packet_queue_purge call to the
821 silc_server_disconnect_remote to assure that all data in the
822 queue before disconnecting is sent to the network. Affected
825 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
827 * Added the deleting of server's own ID cache entry to the
828 silc_server_free function. Free also everything else that
829 has been allocated in silc_server_init. The affected file
832 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
834 * Added functions silc_parse_version_string, silc_version_to_num,
835 and silc_ske_parse_version to parse SILC protocol style version
836 strings. Affected files lib/silcutil/silcutil.[ch] and
837 lib/silcske/silcske.[ch].
839 * Added new configuration params: version_protocol, version_software
840 and version_software_vendor to specify what version the remote
841 host must at least be to be able to connect to server. The vendor
842 string can be regex matched too. Added new function
843 silc_server_connection_allowed to check maximum number of allowed
844 connections, and allowed versions for incoming connections.
845 Affected files are silcd/server.c, server_util.[ch] and
848 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
850 * Added preliminary support for signals in scheduler. The
851 signals we care about are now blocked always when the scheduler
852 is locked. This way we can synchronise the use of signal with
853 scheduler. It is guaranteed that when signal occurs the scheduler
854 is not locked, and thus new tasks can be safely added to the
857 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
858 to silc_schedule_internal_init and silc_schedule_internal_uninit.
859 Added new platform specific routines
860 silc_schedule_internal_signals_[un]block and
861 silc_schedule_internal_signal_[un]register.
863 Added new functions to SILC Schedule API:
864 silc_schedule_signal_[un]register. Each signal that application
865 is going to use should be registered to the scheduler.
867 Affected files are lib/silcutil/silcschedule.[ch],
868 lib/silcutil/*/silc*schedule.c.
870 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
872 * Check for unauthenticated client and server in the
873 silc_server_new_client and silc_server_new_server functions.
874 Affected file silcd/packet_receive.c.
876 * Added function silc_string_is_ascii to check whether given
877 string is 7-bit ASCII string. Affected files are
878 lib/silcutil/silcutil.[ch].
880 * Added function silc_id_is_valid_server_id into the
881 silcd/serverid.c and added checking for valid Server ID's in
882 silc_server_new_server. The Server ID must always be based
883 on the server's public IP address.
885 * Added logging of DISCONNECT packet message in the server.
886 Affected file silcd/server.c.
888 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
890 * Changed all library interfaces that use Global RNG to also
891 accept SilcRng as argument. Affected files are
892 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
893 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
894 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
895 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
898 * Added function silc_pkcs_generate_key to the
899 lib/silccrypt/silcpkcs.[ch] for applications so that they
900 don't need to do pkcs->pkcs->init calls anymore.
902 * Remove SilcSocketConnection from the SFTP API since it really
903 wasn't needed there. The application has the information
904 saved in its contexts anyway and the SFTP layer doesn't need
905 know about it. Affected files lib/silcsft/silcsftp.h and
906 lib/silcsftp/sftp_[server/client].c.
908 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
909 The SilcSimContext is not SilcSim.
911 * Fixed possible buffer overflows in silc_id_render in the
912 lib/silcutil/silcutil.c.
914 * On EPOC the global crypto module lists are not used at all
915 in the crypto library. Added support for using the constant
916 algorithm list on EPOC. Affected files are
917 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
920 * Fixed the handling of third parameter of KICKED notify, since
921 it was mistakenly updated to SILC Protocol 1.0 even though it
922 is to be included in 1.1. Since it is not in 1.0 it is not
923 mandatory, and this fix now handles it only if it is provided,
924 and it is not error if it is not provided. Affected file
925 lib/silcclient/client_notify.c.
927 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
929 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
930 client. Affected file irssi/src/silc/core/client_ops.c.
932 * Merged with Irssi 0.8.4 from irssi.org CVS.
934 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
936 * Check for valid socket connection in client entries before
937 sending any messages. Fixes a crash, but doesn't fix some
938 other underlaying bug that is lurking there. Affected
939 file silcd/packet_send.c.
941 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
943 * $usermode, $cumode and $cumode_space expandos shouldn't do
944 anything with non-SILC server records. Affected file
945 irssi/src/silc/core/silc-expandos.c
947 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
949 * Fixed the silc_net_check_[host/local]_by_sock to support
950 IPv6 bound sockets as well. Now they can return IPv6 addresses
951 as well. Affected file lib/silcutil/silcnet.c.
953 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
954 Affected lib/silcutil/unix/silcunixnet.c.
956 * Fixed ID rendering (at least on some platforms, not NetBSD)
957 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
959 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Added silc_hash_public_key and silc_hash_public_key_compare
962 functions to be used with SilcHashTable. They can be used to
963 hash public keys and compare public keys in hash table. Affected
964 file lib/silcutil/silcutil.[ch].
966 * Added support for specifying multiple public keys for Client
967 connection section in server configuration file. This makes it
968 possible to accept multiple public keys from same host, or to
969 make a section that accepts any incoming host, and have the
970 accepted public keys listed in the section.
972 Added functions silc_sever_[find/get]_public_key, added the
973 support for this actually to all connection sections but only
974 the Client section is currently allowed to specify multiple
977 Affected files are silcd/server.c, server_internal.h,
978 command.c, protocol.c, server_util.[ch], packet_receive.c.
980 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
982 * Merged Irssi 0.8.2 from irssi.org CVS.
984 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
986 * If silc_debug is TRUE, also output standard logging messages
987 to stderr with the debug output.
989 Made silc_log_reset_all() flushing all channels before returning.
990 Also fixed some documentation typos.
992 Affected files are lib/silcutil/silclog.[ch].
994 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
996 * Fixed the server to check correctly the amount of connections
997 from single host, by checking also the type of the connection.
998 Fixed also the comparison of number of connections and number
999 of allowed connections. Affected files are silcd/server.c,
1002 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1004 * Fixed the USERS command reply to save the user's mode on the
1005 channel as well. Fixed JOIN command reply to check whether a
1006 client is on channel already and not join it twice. Affected
1007 file lib/silcclient/command_reply.c.
1009 * Added new file silc-expandos.c into irssi/silc/core/ to return
1010 various stuff for various signal for the statusbar etc. updating.
1011 Now Irssi SILC client prints channel user modes etc. on the
1014 * The user mode (like server/router operator changes) is now shown
1015 on the Irssi SILC client's statusbar. The affected files are
1016 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1018 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1021 to SILC_SCHEDULE_[UN]LOCK macros.

1081 application does not need to define them. Affected file
1082 includes/silcincludes.h.
1084 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1085 old name went against naming convention. Applications now
1086 include "silcclient.h" instead of "clientlibincludes.h".
1087 Removed includes/clientlibincludes.h, it is redundant now.
1089 * Renamed includes/version.h to silcversion.h.
1091 * Added really preliminary support for OS/2 into the util

1149 the SKE interface a bit.
1151 * Fixed padding problem in PKCS#1. The padding was not actually
1152 random since the random number generator was used incorrectly.
1153 This security bug affects only when encrypting with PKCS#1, and
1154 it is not currently used at all in SILC. SILC only use signing
1155 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1218 Affected files irssi/src/silc/core/silc-core.c,
1219 irssi/src/fe-text/silc.c.
1221 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1223 * Added new configuration options and blocks:
1224 keepalive_secs, reconnect_count, reconnect_interval,
1225 reconnect_interval_max, reconnect_keep_trying and

1240 the connection configuration object from the SilcServerConnection
1241 object instead of finding it during the connecting phase.
1242 Added the configuration object to SilcServerConnection struct.
1243 Affected files silcd/server_internal.h, server.c.
1245 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1247 * Add the client on channel after it was resolved at the
1248 channel message receiving, and it was not already on the
1249 channel. Affected file lib/silcclient/client_channel.c.

1269 Added `prefer_passphrase_auth' setting in config file which
1270 can be used to set to prefer passwd auth if both passwd and
1271 public key is set. If not set, public key is preferred.
1272 This has effect only when being initiator (responder will try
1275 Added support for authentication with passphrase and public key
1276 at the same time. The passphrase is tried first always since
1277 it is faster to check.
1279 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1281 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1327 * Fixed the file transfer's key agreement payload to include
1328 zero port also if the hostname is NULL because it could not
1331 Call file transfer monitor callback now also if error occurs
1332 during key agreement protocol.
1334 Changed the silc_client_file_send interface to return the
1335 SilcClientFileError instead of session id. The session ID
1336 is returned into pointer provided as argument.
1338 Check that the file exists locally before sending the
1339 file transfer request at all.
1341 Affected file lib/silcclient/client_ftp.c, silcapi.h.

1405 users list to SilcHashTable. The affected files are
1406 lib/silcclient/idlist.[ch].
1408 * Fixed a bug in hash table tarversing. While the hash table
1409 is traversed with SilcHashTableList the table must not be
1410 rehashed. It is now guaranteed that auto rehashable tables
1411 are not rehashed while tarversing the list. Also defined that
1412 silc_hash_table_rehash must not be called while tarversing
1413 the table. Added function silc_hash_table_list_reset that must
1414 be called after the tarversing is over. The affected files are
1415 lib/silcutil/silchashtable.[ch].
1417 * Changed all hash table traversing to call the new
1418 silc_hash_table_list_reset in server and in client library.
1420 * Added function silc_client_on_channel to return the
1421 SilcChannelUser entry if the specified client entry is joined
1422 on the specified channel. This is exported to application as
1423 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1432 lists correctly. Affected file silcd/command.c.
1434 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1436 * When sending JOIN command to router for processing the
1437 sender's old command identifier was not saved back to the
1438 sender's command context, fixed now. The affected file is
1441 * Create the key in JOIN command of the router did not return
1442 the channel key, added check for this. Affected file is
1445 * Fixed a channel ID update bug in JOIN command reply. Do
1446 not directly upgrade the ID but call the function
1447 silc_idlist_replace_channel_id if the ID was changed.
1448 Affected file silcd/command_reply.c.
1450 * Fixed memory leaks from command calling if it would fail.

1541 * Fixed some double frees from client library commands.
1542 Affected file is lib/silcclient/command.c.
1544 * Fixed CUMODE command in server to assure that no one can

1546 little bug. Affected file silcd/command.c.
1548 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1550 * Removed the SilcClientCommandDestructor from the client
1551 libary, it is not needed anymore. Affected files are
1552 lib/silcclient/silcapi.h, command[_reply].[ch],
1553 client_notify, idlist.c.
1555 * Fixed GETKEY command to first resolve client, and then
1556 resolve the server only if the client was not found, instead
1557 of resolving both at the same time. Affected file is
1558 lib/silcclient/command.c.
1560 * Added silc_client_start_key_exchange_cb and lookup the
1561 remote hostname and IP address before starting the key
1562 exchange with server. The affected file is
1563 lib/silcclient/client.c.
1565 * The server's public key is now saved using the IP address
1566 of the server and not the servername for the filename.
1567 The hostname public key filename is checked as an fall back
1568 method if the IP address based filename is not found.
1570 Fixed the GETKEY command to save the fetched server key
1571 in correct filename.
1573 Print the remote server's hostname now when new key is
1574 received during connection process. Affected file is
1575 irssi/src/silc/core/client_ops.c.
1577 * Return always our own public key to the client if it asks
1578 for it with GETKEY command. Affected file silcd/command.c.
1580 * Removed the use_auto_addr variable from default config
1581 file since it was in wrong section. Affected file is
1584 * Fixed TOPIC_CHANGE notification to not route it when it
1585 was sent using silc_server_send_notify_to_channel function.
1586 Affected file silcd/command.c.
1588 * Fixed silc_server_send_notify_kicked to send the kicker's
1589 Client ID also, it was missing. Affected files are
1590 silcd/command.c, silcd/packet_send.[ch].
1592 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1594 * Do not save client history information in SERVER_SIGNOFF.
1595 Fixes the bug in normal server that it does not detect
1596 the client becoming valid after the server becomes back
1597 online. Affected file silcd/server_util.c.
1599 * Added `sock_error' field into the SilcSocketConnection
1600 context. When error occurs during socket operation (read
1601 or write) the error is saved. Added also new function
1602 silc_socket_get_error to return human readable socket error
1603 message. Affected files are lib/silcutil/silcsockconn.[ch],
1604 lib/silcutil/unix/silcunixsockconn.c, and
1605 lib/silcutil/win32/silcwin32sockconn.c.
1607 * The server now prints the socket error message in the
1608 signoff for client. Affected file silcd/server.c.
1610 * Fixed the `created' channel information sending from router
1611 to server in JOIN command. Checks now whether the channel
1612 really was created or not and set it according that.
1614 Fixed the JOIN command to use the client entry's current
1615 ID during the joining procedure instead of the one it sent
1616 in the command (it is checked though), since it can change
1617 between the packet processing and command processing, and
1618 would just case unnecessary pain in the client end. Affected
1619 file silcd/command.c.
1621 * Fixed a channel key payload sending to use correct channel
1622 ID when the server was forced to change the channel's ID by
1623 router. Router sent the key payload with the old Channel ID.
1624 Affected file silcd/packet_receive.c.
1626 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Call silc_server_save_channel_key only if the key payload
1629 was provided in the JOIN command's command reply. Affected
1630 file silcd/command_reply.c.
1632 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Fixed silc_mp_sizeinbase to return the value correctly with
1635 MPI. Affected file lib/silcmath/mp_mpi.c.
1637 * Fixed the stop_server signal to correctly stop the scheduler
1638 and gracefully stop the server when SIGTERM or SIGINT signals
1639 are received. Affected file silcd/silcd.c.
1641 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1643 * Simple handling of TERM and HUP signals. Also added some log
1644 flushing call around. Affected file is
1647 * Fixed small bugs in silclog.c. Now buffering output will take
1648 effect after 10 seconds since startup: This will ensure that
1649 no important startup messages are lost. Also output redirection
1650 will preserve original format ([Date] [Type] message).
1651 Affected file is lib/silcutil/silclog.c.
1653 * Added two options to the config file, in the logging section:
1654 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1655 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1657 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1659 * Do not print the warning about log files not being initialized
1660 more than once to avoid excess logging. Affected file is
1661 lib/silcutil/silclog.c.
1663 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1664 the SIM copying in make install in Makefile.am.pre.
1666 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1668 * Rewritten silclog APIs. Globally interesting changes follows:
1669 silc_log_set_files() changed to silc_log_set_file().
1670 silc_log_set_callbacks() changed to silc_log_set_callback().
1671 ROBOdoc documented silclog header file.
1672 SilcLogCb now returns bool to wether inihibit the default
1673 handler or not (to keep the old behaviour return always TRUE).
1674 The new APIs should also fix the problem of the
1675 silcd_error.log file that was written in the current directory.
1678 Log files streams will remain opened after silc_log_set_file()
1679 call, means less CPU usage notably on high traffic servers.
1680 File streams are now full buffered, and flushed to the disk
1681 every 5 minutes, lesses HD activity and CPU usage.
1682 Messages can be redirected, allowing admins to configure
1683 one single logfile for all server messages.
1684 the silc_log_quick global variable to activate fast-logging.
1685 Affected files lib/silcutil/silclog.[ch]
1687 * Changed some code to conform new silclog APIs. Affected
1688 files are doc/example_silcd.conf.in, silcd/server.c
1689 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1692 * Fixed a memory leak that could occur in some situations.
1693 Affected file silcd/serverconfig.c.
1695 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1697 * Added the silc_client_del_client to remove the client from
1698 all channels as well. Affected file lib/silcclient/idlist.c.
1700 * Fixed the client library to correctly remove the client
1701 from all channels when the client entry is being destroyed.
1702 Affected file lib/silcclient/client_notify.c, command.c.
1704 * Added auto-nicking support to the client library. If the
1705 applicatio now sets client->nickname it will be sent to the
1706 server after connecting by the library. This way for example
1707 SILCNICK (or IRCNICK) environment variables will have effect
1708 and always change the nickname automatically to whatever
1709 it is wanted. Affected file lib/silcclient/client.[ch].
1711 * Renamed silc_server_command_bad_chars to the
1712 silc_server_name_bad_chars and moved it to the
1713 silcd/server_util.[ch]. Added also new function
1714 silc_server_name_modify_bad to return nickname that
1715 includes bad characters as new nickname without those
1716 bad characters. This check and modify is now used in
1717 silc_server_new_client when the username is initially set
1718 as nickname, so it must be checked to be valid nickname.
1719 Affected file silcd/packet_receive.c.
1721 * The nickname length is now taken from the packet for real
1722 and not trusted to strlen() since it clearly can return
1723 wrong length for nickname including bad characters. This
1724 also applies to channel names. Affected file silcd/command.c.
1726 * Removed the lib/silcsilm/modules directory. Modules are now
1727 compiled into the lib/silcsim. Fixed the copying of the
1728 modules to follow symbolic links in Makefile.am.pre.
1730 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1732 * Fixed silc_string_regexify list creation. Fixes bugs with
1733 BAN and INVITE commands in server. The affected file is
1734 lib/silcutil/unix/silcunixutil.c.
1736 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1738 * Removed the command destructor entirely from the server's
1739 command and command reply routines. It is not needed, and
1740 its usage was buggy and caused crashes. Affected files are
1741 silcd/command[_reply].[ch].
1743 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1745 * Cancel protocol and NULL sock->protocol if timeout
1746 occurred during protocol. Affected file silcd/server.c.
1748 * Cancel protocol timeouts always before calling the final
1749 callback, to assure that after final callback is called
1750 no other state will be called for the protocol anymore.
1751 Affected file silcd/protocol.c.
1753 * Print error log if incoming connection configuration could
1754 not be found. Affected file silcd/server.c.
1756 * Fixed JOIN command to correctly save the founder mode
1757 to the client on normal SILC server, when the channel
1758 was created by the router. Affected file silcd/command.c.
1760 * Fixed LIST command (hopefully) to send correct reply
1761 packets. Affected file silcd/command.c.
1763 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * The silc_packet_receive_process now returns FALSE if the
1766 read data was invalid packet, and TRUE if it was ok.
1768 The server now checks that if unauthenticated connection
1769 sends data and its processing fails the server will close
1770 the connection since it could be a malicious flooder.
1772 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1774 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Make sure the warning about error opening a log file is
1777 printed only once and not everytime it fails (produces
1778 too much useless log). Affected file lib/silcutil/silclog.c.
1780 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1782 * Made the silc_server_daemonise() function more readable.
1783 Affected file silcd/server.c.
1785 * Pid file is now optional, the user may comment it out from
1786 the config file. Removed define SILC_SERVER_PID_FILE, we
1787 don't need a default any longer. Affected file
1788 configure.in.pre, lib/Makefile.am.pre.
1790 * Make some use of the pid file. The server now dies at startup
1791 if it detects a valid pid file on his path. The server would
1792 die anyway in this circumstance, because of the bind() failure.
1793 Affected file silcd/silcd.c.
1795 * No longer compiling lib/dotconf.
1797 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1799 * Fixed JOIN command parsing not to crash. Affected file
1800 lib/silcclient/command.c.
1802 * Fied the NICK_CHANGE notify to add the new client entry
1803 even it is resolved. This removes an <[unknown]> nick
1804 thingy bug in the client. Affected file is
1805 lib/silcclient/client_notify.c.
1807 * Do not try to allocate 0 bytes (efence does not like it)
1808 in lib/silccore/silccomand.c when encoding payload.
1810 * Do not take IRCNICK as nickname in Irssi SILC client since
1811 it is not possible to set nickname before hand connecting
1812 the server (TODO has an entry about adding auto-nicking
1815 * Changed the silc_server_command_pending to check whether
1816 there already exists an pending entry with the specified
1817 command, command identifier and pending callback. This is
1818 to fix IDENTIFY and WHOIS related crashes that may register
1819 multiple pending commands with same identifier. Affected
1820 file silcd/command.c.
1822 * Fixed the server to reconnect to the router even if it
1823 was already reconnecting and EOF was received. This to
1824 fix a possibility that the server wouldn't ever try to
1825 auto-reconnect to the router. Affected file silcd/server.c.
1827 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Fixed the server's password authentication to use the
1830 length of the locally saved password, and not the one
1831 sent in the packet. Affected file silcd/protocol.c.
1833 * Fixed same password authentication problem in the
1834 Authentication Payload handling routines in
1835 lib/silccore/silcauth.c.
1837 * Yet another password authentication problem fixed with
1838 channel password handling in silcd/command.c.
1840 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1842 * If first character of string in silc_parse_userfqdn is '@'
1843 then do not parse it. Affected file is
1844 lib/silcutil/silcutil.c.
1846 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Fixed minor bug in IDENTIFY command reply sending, which
1849 caused various weird problems during JOIN when it was
1850 resolving names for users. Affected file silcd/command.c.
1852 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * Fixed the IDENTIFY command reply sending to chech better valid
1855 clients. It was possible to send incomplete list of replies.
1856 Affected file silcd/command.c.
1858 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1860 * Added silc_client_command[s]_[un]register functions now to
1861 dynamically register the commands in client library. Removed
1862 the static table of commands. This allows the client library
1863 to call commands without causing the application to know about
1864 what commands library has called.
1866 Removed the INFO command reply kludge to detect when the command
1867 was called by library. Now library use its own command reply
1868 function for INFO command.
1870 Added function silc_client_command_call to call a command.
1871 Application can use it to call command, not access the structure
1874 Now all commands that are sent by the client library (not
1875 explicitly sent by application) use own command reply functions.
1877 Affected files around lib/silcclient/ and in
1878 irssi/src/silc/core/.
1880 * Fixed the WHOIS command reply sending to chech better valid
1881 clients. It was possible to send incomplete list of replies.
1883 Fixed the WHOIS and IDENTIFY to send the request to router
1884 if normal server did not do it and did not find any results.
1886 Affected file silcd/command.c.
1888 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1890 * Moved the internal data from SilcClient context into its
1891 own file, not accesible to application. Affected files
1892 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1893 and other files in client library.
1895 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1897 * Added doc/examples installation target in Makefile.am.pre.
1900 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1902 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1903 commands the found client entry will be removed from the
1904 cache, after notifying application about the error. Affected
1905 file lib/silcclient/command_reply.c.
1907 * Changed the /MSG to check for exact nickname user gave, and
1908 not let `nick' match `nick@host' if it is only one found. Now,
1909 user must type the exact nickname (like nick@host2) even if
1910 there are no more than one same nicks found. This is to avoid
1911 a possibility of sending nickname to wrong nickname since
1912 `nick' could match `nick@host'. Affected file is
1913 irssi/src/core/silc-servers.c.
1915 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Do not print "you are now server operator" or similar when
1918 giving /away command. Affected files are
1919 irssi/src/silc/core/client_ops.c, silc-servers.h.
1921 * Made the silc_server_command_pending_error_check to send
1922 the same command reply payload it received back to the
1923 original sender of the command. This way all arguments
1924 that was received by the server will be received by the
1925 client too. Affected file silcd/command.c.
1927 * Added the silc_idcache_add to return the created cache entry
1928 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1930 * Add global clients to expire if they are not on any channel.
1931 This is because normal server will never know if they signoff
1932 if they are not on any channel. The cache expiry will take
1933 case of these entries. This is done by normal servers only.
1934 The affected files are silcd/command_reply.c,
1935 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1937 * If server receives invalid ID notification for WHOIS or
1938 IDENTIFY and the ID exists in the lists, it is removed.
1939 Affected file silcd/command_reply.c.
1941 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1942 in client then client entry that it matches is searched and
1943 the nickname is printed on the screen for user. Affected
1944 file irssi/src/silc/core/client_ops.c.
1946 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Use cache entry expire time in the LIST command reply to
1949 purge old entries from the cache after the LIST command
1950 reply has been received. This way we don't have non-existent
1951 entries in the cache for too long. Affected file is
1952 silcd/command_reply.c.
1954 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * If we are normal server, and we've not resolved client info
1957 in WHOIS or IDENTIFY from router, and it is global client,
1958 we'll check whether it is on some channel. If it is not
1959 then we cannot be sure about its validity and will resolve it
1960 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1961 file silcd/command.c.
1963 * Search channel by name (if possible) rather than by ID
1964 in IDENTIFY command's command reply. Affected file is
1965 silcd/command_reply.c.
1967 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1969 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1970 Updated specs and implemented it. Affected file silcd/command.c,
1971 silcd/packet_send.c and silcd/packet_receive.c.
1973 * Implemented the <founder auth> payload handling in the JOIN
1974 command. If provided all conditions for channel joining
1975 except requirement to provide correct passphrase can be
1976 overrided by the channel founder. Updated the protocol specs.
1977 Affected file silcd/command.c.
1979 Added support for founder auth in JOIN command in client
1980 library. Fixed the parsing of the JOIN command now to support
1981 all options as they should be. The affected file is
1982 lib/silcclient/command.c.
1984 * Optimized the WHOIS and IDENTIFY commands to send the request
1985 to router only if it includes nicknames or other names. If
1986 they include only IDs then check the local cache first before
1987 routing. Affected file is silcd/command.c.
1989 * Added channels topic announcements. Affected file is
1990 silcd/packet_receive.c and silcd/server.c.
1992 * Fixed the silc_server_send_notify_topic_set to really destine
1993 the packet to channel. Affected file silcd/packet_send.c.
1995 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1996 library. Affected file lib/silcclient/client_notify.c.
1998 * Added UMODE announcements. Affected file silcd/server.c.
2000 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Memory leak fixes in:
2004 lib/silcutil/silcsockconn.c
2005 lib/silcske/silcske.c
2006 lib/silcske/groups.c
2008 lib/silccrypt/silcpkcs.c
2009 lib/silccore/silccommand.c
2010 lib/silccore/silcidcache.c
2015 * ROBOdoc documented the lib/silcske/groups.h file and a
2016 bit changed the interface for better.
2018 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2020 * Update the client entry context in the ID cache after
2021 nick change. Affected file lib/silcclient/command.c.
2022 Fixes the CUMODE command when regaining founder privileges,
2023 and a little WHOIS problem.
2025 * Fixed silc_net_gethostbyname to correctly call the
2026 inet_ntop. Affected file lib/silcutil/silcnet.c.
2028 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2030 * Added IPv6 support checking to the configure.in.pre, added
2031 also --enable-ipv6 option to override the check. Affected
2032 file configure.in.pre.
2034 * The silc_thread_create now calls the start function
2035 directly if threads support is not compiled in. Removes
2036 ugly #ifdef's from generic code. Affected files are
2037 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2039 * Added silc_net_gethostby[name/addr]_async to asynchronously
2040 resolve. Affected files are lib/silcutil/silcnet.[ch].
2042 * Added support for rendering IPv6 based server, client and
2043 channel IDs. Affected file lib/silcutil/silcutil.c.
2045 * Added support for creating IPv6 based server IDs. Affected
2046 file is silcd/serverid.c.
2048 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2050 * Added silc_net_gethostby[addr/name] into the
2051 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2052 routines. Added silc_net_is_ip[4/6]. Affected file is
2053 lib/silcutil/unix/silcunixnet.c. All routines that take
2054 address as argument now supports both IPv4 and IPv6 addresses.
2056 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2058 * Fixed LIST command reply sending in server. Affected file
2061 * Server now sends the kicker's client ID in the KICK notify
2062 to the kicked client. Affected file silcd/command.c.
2064 * The client library now parses the kickers client ID and
2065 UI displays it. Affected files lib/silcclient/client_notify.c
2066 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2068 * Made all payload parsing function prototypes consistent.
2069 They all take now const unsigned char * and uint32 pair as
2070 the payload data instead of SilcBuffer. Changes all around
2071 the source tree. Other unsigned char* -> const unsigned char*
2072 changes around the tree as well.
2074 * Optimized SFTP client and server packet sending not to
2075 allocate new buffer for each packet but to recycle the
2076 first allocated buffer. Affected files are
2077 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2079 * Optimized the SFTP client to use SilcList instead of
2080 SilcDList for requests, because it is faster. Affected file
2081 is lib/silcsftp/sftp_client.c.
2083 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2084 into lib/silccore/silcid.[ch].
2086 Renamed silcpayload.[ch] into silcargument.[ch].
2088 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * If client entry is deleted with active key agreement
2091 session, abort the session.
2093 The silc_client_abort_key_agreement now calls the completion
2094 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2096 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2099 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2101 * Don't use __restrict in older GCC's. Affected file is
2102 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2104 * silc_net_localhost now attempts to reverse lookup the
2105 IP/hostname. Affected file lib/silcutil/silcnet.c.
2107 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2108 command. It can be used to gain founder privileges at
2109 the same time when joining the channel.
2111 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2112 kicker's client ID as well. Updated protocol specs.
2114 Defined that the server must send SILC_COMMAND_IDENTIFY
2115 command reply with error status to client who sent
2116 private message with invalid client ID.
2118 Updated the protocol specification.
2120 * Added silc_server_send_command_reply to send any
2121 command reply. Affected file silcd/packet_send.[ch].
2123 * Added silc_id_payload_encode_data to encode ID payload
2124 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2126 * The server now send IDENTIFY command reply with error
2127 status if client ID in private message is invalid. Affected
2128 file silcd/packet_receive.c.
2130 * Save the server key file with server's IP address in
2131 the filename instead of hostname. The affected file is
2132 irssi/src/silc/core/client_ops.c.
2134 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2139 * Added libtool support for compiling shared objects in
2140 lib/silcsim. Affected file configure.in.pre and
2141 lib/silcsim/Makefile.am. Original patch by cras.
2143 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Pid file configuration, and server's config file fixes
2146 patch by toma. Updated CREDITS file.
2148 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2150 * Fixed silc_client_channel_message to not try to decrypt
2151 the message twice if it resolved the destination client
2152 information. This could cause of dropping one channel
2153 message. Affected file lib/silcclient/client_channel.c.
2155 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2158 lib/silcclient/client.c. This function is used when the SILC
2159 Client is run under some other scheduler, or event loop or
2160 main loop. On GUI applications, for example this may be
2161 desired to used to run the client under the GUI application's
2162 main loop. Typically the GUI application would register an
2163 idle task that calls this function multiple times in a second
2164 to quickly process the SILC specific data.
2166 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2168 * Fixed silc_server_drop() for dropping the supplementary
2169 groups as well, this could cause a security hole on some
2172 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2174 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2177 * Write PID file after dropping privileges. Added -F option
2178 to run server on foreground. A patch by debolaz.
2179 Affected files silcd/server.c, silcd/silcd.c.
2181 * Fixed MOTD to return the MOTD file server name. Affected
2182 file silcd/command.c.
2184 * Added INFO command reply handling to the Irssi SILC Client.
2185 Affected file irssi/src/silc/core/client_ops.c.
2187 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Fixed the silc_idcache_list_* routines to really support
2190 the dynamic list. Fixes a crash. Affected file is
2191 lib/silccore/silcidcache.c.
2193 * Fixed the LIST command reply to really call LIST command's
2194 pending callbacks. Affected file silcd/command_reply.c.
2196 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2198 * Update conn->local_entry->nickname after giving NICK
2199 command. Affected file lib/silcclient/command.c.
2201 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2203 * Added the [pid] option to the silcd configuration file
2205 Affected files: serverconfig.[ch] and silcd.c
2207 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Save fingerprint in WHOIS command reply in server.
2210 Affected file silcd/command_reply.c.
2212 * Fixed NICK commands pending callback registration.
2213 Affected file lib/silcclient/command.c.
2215 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2217 * Use ++server->cmd_ident when sending commands in server,
2218 instead of random number. Affected file silcd/command.c.
2220 * Fixed GETKEY command reply to call actually GETKEY pending
2221 command callbacks. Affected file silcd/command_reply.c.
2223 * A bit stricter check for nicknames. Check for same nickname
2224 in NICK command also. Affected file silcd/command.c.
2226 * Do not call INFO command everytime client ID changes, only
2227 during first connecting. Affected file lib/silcclient/client.c.
2229 * Set the new nickname only after successful command reply for
2230 NICK command is returned by server. Affected file
2231 lib/silcclient/command.c.
2233 * Remove nicknames from nicklist during server_signoff notify.
2234 Should fix /NAMES bit more. The affected file is
2235 irssi/src/silc/core/silc-channels.c.
2237 * Added `fingerprint' field to the SilcIDListData in the
2238 silcd/idlist.h to hold the fingerprint of the client's
2241 Send the fingerprint of the client's public key in WHOIS
2244 Affected files silcd/command.c, and silcd/idlist.[ch].
2246 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2247 create fingerprint from given data.
2249 * Show the fingerprint of the client's public key in WHOIS.
2250 Affected files irssi/src/module-formats.[ch] and
2251 irssi/src/silc/core/client_ops.c.
2253 * Format the multiple same nicknames also during JOIN and
2254 NICK_CHANGE notifys. Affected file is
2255 lib/silcclient/client_notify.c.
2257 * Do not print error on screen for invalid private message
2258 payload since it can come if someone is sending private
2259 messages with wrong key. Affected file
2260 lib/silccore/silcprivate.c.
2262 * Fixed multiple concurrent /PING crash. Affected file
2263 lib/silcclient/command.c.
2265 * Changed the wrong ID encoding. All IP addresses must be
2266 in MSB first order in encoded format. They were encoded
2267 wrong and was in LSB format. Affected files are
2268 silcd/serverid.c, lib/silcutil/silcutil.c.
2270 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2272 * Call the `connect' client operation through the scheduler
2273 in case of error. Affected file lib/silcclient/client.c.
2275 * Call the `failure' client operation even if the error
2276 occurred locally during a protocol. Affected file is
2277 lib/silcclient/protocol.c.
2279 * Added support of sending LIST command to router from normal
2280 server. This way normal server can get list of all channels
2281 in the network too. Fixed the channel list sending in the
2282 server too. Affected files are silcd/command.c, and
2283 silcd/command_reply.[ch].
2285 * Added silc_server_update_channels_by_server and
2286 silc_server_remove_channels_by_server. They are used during
2287 disconnection of primary router and in backup router protocol.
2288 Affected file silcd/server_util.[ch], silcd/server.c and
2289 silcd/server_backup.c.
2291 * Fixed channel adding to global list in IDENTIFY command
2292 reply in server. Affected file silcd/command_reply.c.
2294 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2296 * If the incoming packet type is REKEY or REKEY_DONE process
2297 that packet always synchronously. Fixes yet another MAC
2298 failed error on slow (dialup) connections. Affected file
2299 lib/silcclient/client.c and silcd/server.c.
2301 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Call check_version SKE callback for initiator too. Affected
2304 file lib/silcske/silcske.c.
2306 * Implemented fix for security hole found in the SKE that was
2307 fixed in the specification few days back; the initiator's
2308 public key is now added to the HASH value computation.
2309 Added backwards support for the old way of doing it too, for
2310 old clients and old servers. Affected file is
2311 lib/silcske/silcske.c.
2313 * Enabled mutual authentication by default in SKE. If initiator
2314 is not providing mutual authentication the responder will
2315 force it. This will provide the proof of posession of the
2316 private key for responder. The affected files are
2317 lib/silcclient/protocol.c and silcd/protocol.c.
2319 * Do not cache anymore the server's public key during SKE.
2320 We do mutual authentication so the proof of posession of
2321 private key is done, and if the server is authenticated in
2322 conn auth protocol with public key we must have the public
2323 key already. Affected file silcd/protocol.c.
2325 * Added new global debug variable: silc_debug_hexdump. If
2326 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2327 file lib/silcutil/silclog.[ch].
2329 * Fixed compilation warning due to char * -> const char *.
2330 Affected files lib/silcutil/silcnet.h, and
2331 lib/silccore/silcauth.[ch].
2333 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2335 * Fixed CMODE command when new channel key was created. If
2336 the creation failed the old key was removed. Next time giving
2337 same command would crash the server since the old key was
2338 freed already. Affected file silcd/command.c.
2340 * Fixed the silc_server_announce_get_channels to not crash
2341 on reconnect. Affected file silcd/server.c.
2343 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Added silc_log_set_debug_string function to set a regex
2346 string to match for debug output. Only the function names,
2347 or filenames matching the given debug string is actually
2348 printed. This way it is possible to filter out those debug
2349 strings that user is not interested in.
2351 Fixed a bug in silc_string_regexify.
2353 Affected files lib/silcutil/silclog.[ch], and
2354 lib/silcutil/unix/silcunixutil.c.
2356 * Changed the -d options in both server and Irssi SILC client
2357 to take the debug string as argument. Affected files
2358 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2360 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Added silc_hash_babbleprint to create a Bubble Babble
2363 Encoded fingerprint. The encoding is developed by Antti
2364 Huima (draft-huima-babble-01.txt), and it creates human
2365 readable strings out of binary data. Affected file
2366 lib/silccrypt/silchash.[ch].
2368 * Print the babble print now in addition of fingerprint as well
2369 in Irssi SILC client. Affected files are
2370 irssi/src/fe-common/silc/module-formats.[ch],
2371 irssi/src/fe-common/silc/core/client_ops.c.
2373 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Fixed a security problem found in SKE. The initiator's
2376 public key too is now added to the HASH hash value creation
2377 which is signed by the responder to create the SIGN value.
2378 This will prevent anyone in the middle to lie to the responder
2379 about the initiator's public key. If this is done now, the
2380 man in the middle will get caught. Updated the protocol
2383 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Better installation directory handling. Configure module
2386 paths and other paths automatically to example_silc* files
2387 in doc/. A patch by toma.
2389 * Fixed compiler warning from MPI library, and from SILC RNG.
2392 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2393 It can be configured with ./configure. A patch by toma.
2395 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2397 * Find correct make to use in prepare-clean. A patch by
2398 toma. Affected file prepare-clean.
2400 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2402 * Added irssi variables use_auto_addr, auto_bind_ip,
2403 auto_bind_port and auto_public_ip.
2405 * Changed the interface for silc_client_send_key_agreement
2406 in lib/silcclient/silcapi.h
2410 irssi/src/silc/core/silc-core.c
2412 lib/silcclient/silcapi.h
2413 irssi/src/silc/core/silc-channels.c
2414 lib/silcclient/client_keyagr.c
2417 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Added silc_pkcs_public_key_compare to compare two
2420 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2422 * Check that the client who set the founder mode on the
2423 channel is the same client that is giving the founder
2424 mode to itself. It is done by comparing the saved public
2425 key (it is saved even in the authentication is passphrase).
2426 Affected file silcd/command.c.
2428 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2430 * Do not process packet for disconnected socket connection.
2431 Affected file lib/silccore/silcpacket.c.
2433 * Process the DISCONNECT packet through scheduler in the
2434 client library. Affected file lib/silcclient/client.c.
2436 * Fixed the silc_client_packet_parse to not to increase
2437 the packet sequence number if the conn->sock and the
2438 current socket connection is not same. This can happen
2439 for example during key agreement when the conn includes
2440 multiple socket connections (listeners). Affected file
2441 lib/silcclient/client.c.
2443 * The sender of the file transfer request now provides also
2444 the pointer (listener) for the key exchange protocol. If
2445 the listener cannot be created then it sends empty key
2446 agreement and lets the receiver provide the listener.
2448 Added `local_ip' and `local_port' arguments to the
2449 silc_client_file_send. If they are provided they are used,
2450 if not then it will attempt to find local IP address, if
2451 not found or bind fails then the remote client will provide
2454 Affected files are lib/silcclient/client_ftp.c and
2455 lib/silcclient/silcapi.h.
2457 * Extended the FILE SEND command to support defining the
2458 local IP and port for key exchange listener. They are
2459 optional. Affected file irssi/src/silc/core/silc-servers.c.
2461 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Defined to WHOIS command reply the sending of fingerprint
2464 of the client's public key (if the proof of posession of the
2465 corresponding private key is verified by the server).
2466 Updated to the protocol specification.
2468 * Added support of receiving the client's public key's
2469 fingerprint in command reply in client library. Affected
2470 file is lib/silcclient/command_reply.c, and
2471 lib/silcclient/idlist.[ch].
2473 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2475 * Do not send over 128 chars long nickname to the server
2476 in NICK command. Affected file lib/silcclient/command.c.
2478 * Do not send over 256 chars long channel names to the server
2479 in JOIN command. Affected file lib/silcclient/command.c.
2481 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Assure that silc_server_close_connection cannot be called
2484 twice for same socket context. Affected file is
2487 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Send error message to application if opening file for
2490 writing during file transfer fails. Affected file is
2491 lib/silcclient/client_ftp.c.
2493 Remove all file transfer sessions for a client that we're
2494 removing from ID cache.
2496 Affected file is lib/silcclient/client_ftp.c.
2498 * Fixed silc_net_addr2bin to return correct address. Affected
2499 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2501 * Fixed file transfer session removing on signoff notify.
2502 Affected file irssi/src/silc/core/silc-servers.c.
2504 * Added the SilcClientFileError to be returned in the monitor
2505 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2506 Affected file lib/silcclient/silcapi.h.
2508 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Fixed a crash in silc_client_ftp_free_sessions and
2511 silc_client_ftp_session_free_client. Affected file
2512 lib/silcclient/client_ftp.c.
2514 * Added `disabled' field in the SilcChannelEntry in the server
2515 to indicate if the server entry is disabled. Affected file
2516 silcd/idlist.h, silcd/command[_reply].c.
2518 * SILC server adds now /var/run/silcd.pid everytime it is
2519 started. Affected file silcd/silcd.c.
2521 * Added silc_server_packet_send_clients to send a packet to
2522 the provided table of client entries. Affected file
2523 silcd/packet_send.[ch].
2525 * Fixed a crash in client resolving in client_prvmsg.c in
2526 client library. Affected file lib/silcclient/client_prvmsg.c.
2528 * Do not actually remove the client directly from ID cache
2529 during SERVER_SIGNOFF, but invalidate it. This way we
2530 preserve the WHOWAS info for the client. Affected file
2531 silcd/server_util.c.
2533 * Fixed SERVER_SIGNOFF notify handling in the server. The
2534 server is now able to process incoming SERVER_SIGNOFF notify
2535 for a server that it doesn't even know about. It will remove
2536 the clients provided in the notify. Affected file
2537 silcd/packet_receive.c.
2539 * Check for partial packet in data queue after every packet that
2540 was found from the queue. Return and wait for more data if
2541 there is partial data in queue. Affected file is
2542 lib/silccore/silcpacket.c.
2544 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2546 * Added SilcClietFileError enum to indicate error in
2547 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2548 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2549 Affected files lib/silcclient/silcapi.h and
2550 lib/silcclient/client_ftp.c.
2552 * Check that newsize in silc_buffer_realloc is larger than
2553 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2555 * Added better monitor of file transfers. It now monitors
2556 key agreement protocol during the file transfer too. Added
2557 error reporting too. Affected files
2558 irssi/src/silc/core/silc-servers.c,
2559 irssi/src/fe-common/silc/module-formats.[ch].
2561 * Wrote a help file for FILE command.
2563 * Added silc_rng_global_get_byte_fast to get not-so-secure
2564 random data as fast as possible. Random data is read from
2565 /dev/urandom if available and from the SILC RNG if not
2566 available. It is used in padding generation. Affected file
2567 lib/silccrypt/silcrng.[ch].
2569 * All packets in client library are now processed synchronously.
2570 Optimized packet processing a lot. Affected file
2571 lib/silcclient/client.c.
2573 * All server connection packets are processing synchronously
2574 now in server, to optimize packet processing. Affected file
2577 * Include files are installed now only in Toolkit distribution
2578 if make install is given. Affected files: all Makefile.am's.
2580 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Assure that silc_client_notify_by_server_resolve does not
2583 resolve the client information multiple times. If it cannot
2584 be found by the first it cannot be found at all. Affected
2585 file lib/silcclient/client_notify.c.
2587 * Fixed WHOWAS command reply calling. Affected file
2588 lib/silcclient/command_reply.c.
2590 * Removed all references to silc_idlist_get_client from the
2591 Irssi SILC client since that call is internal call used by
2592 the library. The Irssi SILC client will use now client
2593 retrieval functions found in silcapi.h.
2595 * Fixed a bug in resolving nickname info before sending
2596 private message. It used freed memory. Affected file
2597 irssi/src/silc/core/silc-servers.c.
2599 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Assure my_channels statistics cannot go negative in server.
2602 Affected files silcd/server.c, silcd/server_util.c.
2604 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2608 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

2618 * Added silc_net_localip to return local host's IP address.
2619 Affected file lib/silcutil/silcnet.[ch].
2621 * If key exchange or rekey protocol is active for a connection
2622 parse all packets syncronously since there might be packets
2623 in packet queue that we are not able to process without first
2624 processing packets before them. Affected file silcd/server,
2625 lib/silcclient/client.c.
2627 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2628 whether library should continue processing the packet.
2629 Affected file lib/silccore/silcpacket.h.
2631 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2632 SilcSFTPMonitorData to SFTP server to monitor various

2664 * Resolve the client info when received private message or
2665 channel message for a client which nickname we don't know.
2666 Affected files lib/silcclient/client_prvmsg.c and
2667 lib/silcclient/client_channel.c.

2675 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2676 is incomplete and is being resolved, it won't be resolved
2679 Make sure also that USERS command reply does not resolve
2680 twice information. Affected file is
2681 lib/silcclient/command_reply.c.
2683 Make sure that silc_client_get_clients_by_list does not
2684 resolve twice same information.
2686 * Check for valid client->id in the silc_server_free_client_data.
2687 Affected file silcd/server.c.
2689 * Fixed /GETKEY nick@server not to crash if the server entry
2690 is not found. Affected file lib/silcclient/command.c.
2692 * Fixed the silc_server_check_cmode_rights to check the

2698 Affected file silcd/command.c.
2700 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Call the silc_server_udpate_servers_by_server in the
2703 primary router that comes back online in the backup resuming
2704 protocol. Otherwise it routes packets wrong. Affected file
2705 silcd/server_util.[ch], silcd/server_backup.c.
2707 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2709 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2710 lib/silcutil/silcbuffmt.[ch].
2712 * Redefined the SILC packet header to include the padding
2713 length. Affected file lib/silccore/silcpacket.[ch].
2715 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2716 length for maximum padding up to 128 bytes). Affected
2717 file lib/silccore/silcpacket.h.
2719 * Removed all backwards support for old 0.5.x MAC thingies.
2720 The SILC packet header change makes it impossible to be
2721 backwards compatible.
2723 * Send the ENDING packet with timeout in the backup resuming
2724 protocol. This is to assure that all routers has connected
2725 to the primary router. Affected file silcd/server_backup.c.
2727 * Changed the RNG to take the first IV from random data. It
2728 used to take it from zero actually. Changed the RNG also
2729 to use /dev/urandom during session. /dev/random is used
2730 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2732 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Changed the SILC packet header to have the first two bytes
2735 (the packet length) encrypted. Affected files aroung the
2736 code tree, lib/silccore/silcpacket.[ch]. Removed the
2737 SilcPacketCheckDecrypt callback. It is not needed anymore
2738 since the silc_packet_receive_process will determine now
2739 whether the packet is normal or special.
2741 * Implemented the unidirectional MAC keys. Affected files
2742 lib/silcske/silcske.c, silcd/protocol.c and
2743 lib/silcclient/protocol.c.
2745 * Implemented the packet sequence number to the MAC computation.
2746 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2747 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2748 lib/silcclient/protocol.c.
2750 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2752 * Allow backup router to announce servers. All servers
2753 announced by backup router are added to the global list
2754 automatically. Update hte server's socket to our primary
2755 router also when backup router announces a server.
2756 Affected file silcd/packet_receive.c.
2758 * Do not update the client->router in the function
2759 silc_server_udpate_clients_by_server if the client is on
2760 global list. We might fail to find any specific server
2761 for locally connected clients and local cell clients. They
2762 should still use the `from' and not `to' as client->router.
2763 This fixes backup router resuming protocol. Affected file
2764 silcd/server_util.c.
2766 * Decrease channel statistics count only if the channel
2767 deletion worked. Affected files are silcd/server.c and
2768 silcd/server_util.c.
2770 * Added silc_server_update_servers_by_server to update origin
2771 of all server entries. Used during backup router protocol.
2772 Affected files silcd/server_util.[ch], silcd/server.c. and
2773 silcd/backup_router.c.
2775 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2776 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2777 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2778 lib/silccrypt/silchmac.c.
2780 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Assure that router cannot reroute the same channel message
2783 to the sender. Affected file silcd/packet_receive.c.
2785 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Made better checks that the channel message is not sent
2788 to the router it came from. Affected file is
2789 silcd/packet_send.c. Fixed memory leak too.
2791 * Announce informations for incoming router connection, but
2792 only after checking if it is replaced by backup router.
2793 Affected file silcd/packet_receive.c.
2795 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Fixed the backup resuming protocol to work in multiple
2798 router environment. Affected file silcd/server_backup.c.
2800 * Route packet only to one router in the function
2801 silc_server_packet_send_to_channel. Affected file is
2802 silcd/packet_send.c.
2804 * Fixed silc_server_send_notify_dest to set the broadcast
2805 flag. Fixed the silc_server_send_notify_topic to actually
2806 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2807 Affected file silcd/packet_send.c.
2809 * Changed the SFTP Filesystem interface. Changed the
2810 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2811 the filesystem operation function. The SilcSFTPFilesystem
2812 is now a context that is allocated by all filesystem allocation
2813 functions and it already includes the operations structure
2814 and filesystem specific context. It is given as argument
2815 now to the silc_sftp_server_start. This made the interface
2816 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2817 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2819 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Changed the backup router adding and getting interfaces
2822 in the server. The router that will be replaced by the
2823 specified backup router is now sent as argument. Affected
2824 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2827 * Added silc_net_addr2bin_ne to return the binary form of
2828 the IP address in network byte order. Affected files
2829 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2831 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Check for existing server ID in silc_server_new_server
2834 and in silc_server_connect_to_router_final and remove the
2835 old entry if it exists. Affected file silcd/packet_receive.c,
2838 * Send the channel message always to only one router, either
2839 in upstream or downstream. Affected file is
2840 silcd/packet_send.c.
2842 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Wrote the definition of the backup resuming protocol to the
2845 protocol specification.
2847 * Removed one redundant channel key generation from normal
2848 server during joining procedure. Removed one redundant
2849 channel key sending from server to router during joining
2850 procedure. Affected file silcd/command.c.
2852 * Made minor bugfixes to the backup router resuming protocol.
2853 Affected file silcd/server_backup.c, server.c.
2855 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2858 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2861 * Implemented the backup resuming protocol that is used to
2862 resume the primary router position in the cell after the
2863 primary router comes back online. Affected files
2864 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2865 and silcd/server_util.[ch].
2867 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * Sleep two (2) seconds after sending QUIT command to server.
2870 Affected file lib/silcclient/command.c.
2872 * Assure that if outgoing data buffer is pending do not force
2873 send any data. Affected file silcd/packet_send.c.
2875 * Assure that if outgoing data buffer is pending do not force
2876 send any data. Affected file lib/silcclient/client.c.
2878 * Implemented the backup router support when the primary router
2879 goes down. The servers and routers can now use the backup
2880 router as new primary router without loosing connectivity.
2882 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2885 in the server to indicate disabled entry. All data read
2886 from the connection will be ignored and no data is sent
2887 for entry that is disabled. Affected files are
2888 silcd/idlist.h, silcd/server.c.
2890 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Created SFTP client and server test programs in the
2893 lib/silcsftp/tests directory.
2895 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Implemented memory filesystem (virtual filesystem) for
2898 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2901 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Implemented the SFTP (SSH File Transfer Protocol) to the
2904 lib/silcsftp. It includes SFTP client and SFTP server
2907 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2909 * Moved lib/silccore/silcprotocol.[ch] to the
2910 lib/silcutil library.
2912 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2913 take variable argument list pointer as argument. Affected
2914 file lib/silcutil/silcbuffmt.[ch].
2916 * Added silc_buffer_set function that is used to set data
2917 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2918 Affected file lib/silcutil/silcbuffer.h.
2920 * Changed various routines in the core library to use the new
2921 silc_buffer_set instead of allocating new buffer only for
2924 * Added 64-bit value formatting and unformatting support to the
2925 silc_buffer_[un]format routines. Affected file is
2926 lib/silcutil/silcbuffmt.[ch].
2928 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2929 to includes/bitmove.h.
2931 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Fixed channel user mode saving in client library. Affected
2934 file lib/silcclient/command[_reply].c.
2936 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2938 * Defined the file transfer to the SILC Protocol. Added
2939 new packet type SILC_PACKET_FTP and defined File Transfer
2940 Payload. The mandatory file transfer protocol is SFTP
2941 (SSH File Transfer Protocol). Affected file in addition
2942 of the internet draft is lib/silccore/silcpacket.h.
2944 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2945 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2946 is used as part of backup router protocol when the primary
2947 router of the cell is back online and wishes to resume
2948 the position as primary router.
2950 * Redefined the MAC generation keys in the protocol. The
2951 same key is not used anymore in both direction. Both
2952 direction will now use different keys for sending and
2953 receiving. This fixes a potential security flaw. This
2954 change causes incompatibilities in the protocol.
2956 * Redefined also the MAC computation from the packet.
2957 An packet sequence number is now added to the MAC
2958 computation. This prevents possible replay attacks against
2959 the protocol. This change too causes incompatibilities
2962 Added `sequence' field to the SilcPacketContext to hold
2963 the current sequence number for the packet.
2965 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Added `created' field to the SilcIDListData in the file
2968 silcd/idlist.h to indicate the time when the entry was
2971 * Added `created' field to the SilcChannelEntry too. Affected
2972 file silcd/idlist.h.
2974 * Added `creation_time' aguments to all the announcement functions
2975 in the server. If it is provided then only the entries that
2976 was created after the provided time frame are actually
2977 announced. Affected file silcd/server.[ch].
2979 * The protocol says that the Channel ID's IP address must be
2980 based on the router's IP address. Added check for this in
2981 the silc_server_new_channel when processing incoming New Channel
2982 Payload. Affected file silcd/packet_receive.c.
2984 * Print out the correct version with --version in SILC client.
2985 Affected file irssi/src/silc/core/silc-core.c.
2987 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Fixed WHOWAS command to check for completnes of the client
2990 entry always, not just when the command is coming from client.
2991 Affected file silcd/command.c.
2993 * Added new function silc_server_packet_queue_purge to purge the
2994 outgoing data queue to the network. After the function returns
2995 it is guaranteed that the outgoing packet queue is empty.
2996 Affected file silcd/packet_send.[ch].
2998 * Purge the outgoing packet queue in the rekey protocol's final
2999 callback to assure that all rekey packets go to the network
3000 before quitting the protocol. Affected file silcd/server.c.
3002 * Added silc_client_packet_queue_parse as similar function as
3003 in server to the client library. The affected file is
3004 lib/silcclient/client.c.
3006 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Splitted silcd/server.c and created silcd/server_util.[ch]
3009 for utility functions.
3011 * Added new socket flag SILC_SF_DISABLED to indicate that the
3012 connection is open but nothing can be sent to or received from
3013 the connection. Affected file lib/silcutil/silsockconn.[ch].
3014 The checking for disabled socket is checked in the low level
3015 silc_socket_write and silc_socket_read functions.
3017 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Allow only nicknames and channel names that fits into the
3020 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3022 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * When processing JOIN command reply in server check that if
3025 the channel exists in our global list we'll move it the local
3026 list. Affected file silcd/command_reply.c.
3028 * Fixed the check whether client is joined on the channel already
3029 in JOIN command. Affected file lib/silcclient/command.c.
3031 * Fixed the JOIN command reply to check whether the channel
3032 already exists. Affected file lib/silcclient/command_reply.c.
3034 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Added silc_ske_status_string to map the SKE error numbers
3037 to readable strings. The affected files are
3038 lib/silcske/silcske[_status].[ch].
3040 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Do not show the private channels on the WHOIS channel list
3043 as it is not allowed by the protocol. The affected file is
3046 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Assure that the packet length digged from the actual packet
3049 is something sensible in the silc_packet_decrypt_rest_special
3050 in lib/silccrypt/silcpacket.c.
3052 * Free and NULL the allocated pointer in silc_hmac_alloc if
3053 the HMAC allocation fails. The affected file is
3054 lib/silccrypt/silchmac.c.
3056 * Print the selected security properties to the log files in
3057 the server. Affected file silcd/protocol.c.
3059 * Add SKE's reference counter even if calling the completion
3060 callback manually. Otherwise it goes negative, although it
3061 does not cause any problems. The affected file is
3062 lib/silcske/silcske.c.
3064 * Remove the client entry with short timeout after giving the
3065 KILL command. Affected file lib/silcclient/command.c.
3067 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3068 case all found clients are already disconnected (WHOWAS would
3069 found them) in the server. Affected file silcd/command.c.
3071 * Update the last_receive (time of last data received) to be
3072 updated only when received private or channel message so that
3073 the idle time showed in WHOIS makes more sense.
3075 * Added boolean field `valid' in to the SilcClientEntry in the
3076 client library to indicate whether the entry is valid or not.
3077 This fixes the nickname change bug on channel when changing
3078 the nickname to be same than the old (like nick to Nick) the
3079 nickname formatter doesn't set the new nick anymore to Nick@host.
3080 Affected file lib/silcclient/idlist.[ch].
3082 * Now actually fixed the nickname changing on disconnection.
3083 Added new function silc_change_nick to the Irssi SILC Client.
3084 Affected file irssi/src/silc/core/client_ops.c,
3085 irssi/src/silc/core/silc-nicklist.[ch].
3087 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Check that the public key exists in the GETKEY command before
3090 trying to encode it. Affected file silcd/command.c.
3092 * Print some notifications on received public keys with GETKEY
3093 command in the Irssi SILC Client. Affected files are
3094 irssi/src/fe-common/silc/module-formats.[ch],
3095 irssi/src/silc/core/client_ops.c.
3097 * Use IDENTIFY command to resolve the server information in the
3098 GETKEY command instead of INFO command. Affected file
3099 lib/silcclient/command.c.
3101 * All command reply functions in the client library now calls
3102 the pending command reply callbacks even if an error has
3103 occurred. The server has done this a long time and now it was
3104 time to move the client library to this as well. Now all
3105 errors can be delivered back to the pending command reply
3106 callbacks if necessary. Affected files are
3107 lib/silcclient/command[_reply].[ch].
3109 * Change the nickname on disconnection back to the username
3110 because in reconnect the server will enforce it to it anyway.
3111 Affected file irssi/src/silc/core/silc-servers.c.
3113 * Fixed a config file parsing bug in the Irssi SILC client.
3114 Affected file irssi/src/silc/core/clientconfig.c.
3116 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * When printing the channel mode on JOIN, verify that the
3119 channel key and channel's HMAC are valid. Affected file
3120 irssi/src/silc/core/client_ops.c.
3122 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3125 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3126 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3128 * Removed channel key rekey task deleting from the function
3129 silc_server_save_channel_key. Affected file silcd/server.c.
3130 Added explicit timeout task context instead that is used to
3131 delete the task if we are registering a new task before the
3132 new task has elapsed.
3134 * When channel key rekey occurs the client library now saves
3135 the old channel key for a short period of time (10 seconds) and
3136 is able to use it in case some is still sending channel
3137 messages encrypted with the old key after the rekey. Affected
3138 file lib/silcclient/[idlist.h|client_channel.c].
3140 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3142 * Added check to the silc_server_new_id_real to not accept
3143 new ID if it is the sender's own ID. Affected file is
3144 silcd/packet_receive.c.
3146 * Assure that we do not announce ourself or the one we've
3147 sending our announcements when we're router and are announcing
3148 servers to our primary router. Affected file silcd/server.c.
3150 * Fixed silc_server_command_identify_check_client to assemble
3151 correct WHOIS packet. It send corrupted WHOIS packet and
3152 caused problem with router to router connections. Affected
3153 file silcd/command.c.
3155 Fixed also silc_server_command_whois_check the same way
3156 as for the IDENTIFY command.
3158 * Added new SilcIDListStatus to the server in the SilcIDListData
3159 structure. The status now includes the current status of
3160 the entry (like registered, resolved etc.). Affected file
3161 silcd/idlist.[ch]. Defined a bunch of different status types
3162 as well. This replaced the old boolean registered field as well.
3164 Added resolve_cmd_ident field to the SilcClientEntry structure
3165 too so that if the entry is for example being resolved so
3166 another command may attach to the same pending command reply
3167 without requiring to resolve the same entry again. This concept
3168 should optimize the WHOIS and the IDENTIFY resolving under
3169 heavy load by taking away unnecessary resolving for entries
3170 that are being resolved already.
3172 Added support for adding multiple pending commands for one
3173 command idenfier. Affected file silcd/command[_reply].[ch].
3175 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3176 before deleting the data. Otherwise the hash table will have
3177 freed data in comparison functions. Affected file is
3178 silcd/command_reply.c.
3180 * Fixed silc_idlist_replace_client_id to add the new entry to
3181 the cache with NULL nickname. Otherwise there will be invalid
3182 memory as the nickname after the nickname is freed. Affected
3183 file silcd/packet_receive.c.
3185 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3186 saved into wrong slots because the previous number of entries
3187 was not taken into account. Affected file silcd/idlist.c.
3188 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3190 * If we are router and we receive JOIN notify to a channel that
3191 does not have any users then notified client is marked as the
3192 channel founder, as it is it. The affected file is
3193 silcd/packet_receive.c
3195 * Added to the extended hash table API's table_del_*ext functions
3196 the destructor as argument too, so that the caller can decide
3197 which destructor to use or whether to use destructor at all.
3198 Affected file lib/silcutil/silchashtable.[ch].
3200 * Fixed ID Cache purging. It actually deleted the entries from
3201 the hash table after the data was freed. The hash table ended
3202 up comparing freed memory. The affected file is
3203 lib/silccore/silcidcache.c.
3205 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Fixed Irssi SILC client's KILL command's HELP syntax.
3209 * The USERS command now resolves the detailed user information
3210 if the userinfo field is missing. Affected file is
3211 lib/silcclient/command_reply.c.
3213 * Do not print error in silc_file_read if the read file does
3214 not exist. Just silently return NULL. Affected file is
3215 lib/silcutil/silcutil.c.
3217 * Fixed the silc_log_output to not wine about NULL filename
3218 and to not create some bogus " " filename. Affected file is
3219 lib/silcutil/silclog.c.
3221 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * Fixed various printing bugs on the user interface in the
3224 Irssi SILC Client. Minor changes that were forgotten from
3227 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Fixed the configure.in.pre and the compilation and distribution
3230 environment to support the new autoconf 2.52. That version is
3231 now required to compile the CVS trunk.
3233 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3235 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3236 to generally parse user@fqdn format strings. Affected file
3237 lib/silcutil/silcutil.c.
3239 * Added nickname_format and nickname_force_format fields to the
3240 SilcClientParams structure. The first one defines the format
3241 for the nicknames that the library will enforce if the receives
3242 multiple same nicknames. The second one is boolean value and
3243 can be used to force the library to always enforce the format
3244 to the nicknames regardles whether there are multiple nicknames
3245 or not. This configurable formatting was employed to flexibly
3246 support accessing multiple nicknames from the user interface.
3247 The userinterface can now set the nicknames to what ever format
3248 they prefer. Affected file lib/silcclient/silcapi.h.
3250 Added function silc_client_nickname_format to the file
3251 lib/silcclient/idlist.c. It performs the nickname formatting.
3253 Added new field `hostname´ to the SilcClientEntry context.
3254 It holds the hostname of the client. Affected file is
3255 lib/silcclient/idlist.h.
3257 * Irssi SILC Client sets the nicknames in nick@hostn format.
3258 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3259 irssi/src/silc/core/silc-core.c.
3261 The WHOIS printing now also shows both the real nickname and
3262 the formatted nickname so that user knows how to access the
3263 user if there are multiple same nicknames cached. Affected
3264 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3265 printing formatting too to take the hostname now as a separate
3266 argument. The Affected file is
3267 irssi/src/fe-common/silc/modules-formats.[ch].
3269 * Changed the silc_client_get_clients_local to accept the formatted
3270 nickname as argument. It accepts the real nickname too but the
3271 formatted nickname can be used to find the true entry from
3272 multiple entries. Affected file lib/silcclient/silcapi.h and
3273 lib/silcclient/idlist.c.
3275 * Added nickname_format_parse field to the SilcClientParams.
3276 It is a callback function provided by the application to parse
3277 the nickname out of the formatted nickname string. The library
3278 calls it to get the nickname from the formatted string. Since
3279 the application generally knows better the format of the nickname
3280 string it parses it instead of the library, even though library
3281 encodes the formatted string. If the callback function is not
3282 provided then the library will use the string as is. The
3283 affected file is lib/silcclient/silcapi.h.
3285 * All the nickname strings passed to the client library in
3286 commands are now expected to be formatted nickname strings.
3287 If the command does not support the formatted nickname string
3288 it will assume that the sent string is the actual nickname.
3289 Affected file lib/silcclient/command.c.
3291 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Added public key authentication support to OPER and SILCOPER
3294 commands in the client library. Affected file is
3295 lib/silcclient/command.c.
3297 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Changed the get_auth_methdod client operation to be asynchronous.
3300 It can be async if the application resolves the authentication
3301 method from the server during the negotiation. Added new
3302 SilcGetAuthMeth completion callback that the application will
3303 call after resolving the authentication method.
3305 Added function silc_client_request_authentication_method that
3306 the application can use to resolve the authentication method
3307 from the server. Added also SilcConnectionAuthRequest callback
3308 that the library will call after the server has replied. The
3309 application can call this function if it does not know the
3310 current authentication method.
3312 Affected files are lib/silcclient/client.c and
3313 lib/silcclient/silcapi.h.
3315 * The Irssi SILC client now automatically resolves the authentication
3316 method incase any configuration information is not present (and
3317 currently there never is). The affected file is
3318 irssi/src/silc/core/client_ops.c.
3320 * Fixed public key authentication from the client library.
3321 Affected file lib/silcclient/protocol.c. Changed also the
3322 protocol specification about the public key authentication in
3323 the connection authentication protocol. The actual data to be
3324 signed is now computed with a hash function before signing.
3326 * Fixed the public key authentication from the server as well.
3327 Affected file silcd/protocol.c.
3329 * Removed the mlock()'s from the memory allocation routines.
3330 Affected file lib/silcutil/silcmemory.c. The ./configure does
3331 not check anymore for the mlock(). Affected file is
3334 * Fixed USERS command in server to allow the execution of the
3335 command for private and secret channels if the client sending
3336 the command is on the channel. Affected file silcd/command.c.
3338 * Fixed silc_client_get_clients_local to return the clients
3339 count correctly. It could return wrong value. Affected file
3340 lib/silcclient/idlist.c.
3342 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3345 types. The assembler optimizations seemed not to like 64-bit
3346 data types. The assmebler optimizations thus are now enabled
3347 also for BSD systems as opposed to only enable them for Linux.
3349 * Do not check for threads at all on BSD systems. Affected
3350 file configure.in.pre.
3352 * Removed -n and -h options from the Irssi SILC Client since
3353 they are not used in silc.
3355 * Fixed the prime generation to assure that the first digit
3356 of the generated random number is not zero since our conversion
3357 routines does not like number strings that starts with zero
3358 digit. If zero digit is seen the random number is regenerated.
3359 This caused some corrupted RSA keys when the zero first digit
3360 was met. Affected file lib/silcmath/silcprimegen.c.
3362 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * Fixed WIN32 configuration in the ./configure script.
3365 Fixed to include xti.h on environments that has it.
3366 Patches by Carsten Ilchmann and andrew.
3368 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3370 * Changed the silc_id_create_client_id to be collision
3371 resistant. It is now assured that there cannot be created
3372 two same client ID's. I suspect that some weird bugs in
3373 the server were actually caused by duplicate Client IDs.
3374 Affected file silcd/serverid.[ch]. A router receiving
3375 new ID now also assures and informs the sending server
3376 if the ID caused collision.
3378 * Changed the silc_id_create_channel_id to also assure that
3379 there are no collisions.
3381 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * Statement about ignoring the Mutual Authentication flag when
3384 performing rekey with PFS was a bit misleading. It is ignored
3385 if it was set in the initial negotiation, it cannot be even
3386 set in the rekey. Fixed in the ke-auth draft. Started the
3387 new versions of the protocol drafts in the doc/.
3389 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3391 * Fixed a bug in silc_client_command_identify_save when saving
3392 new channel information. The channel name was no duplicated
3393 and caused crash on exit. Affected file is
3394 lib/silcclient/command_reply.c.
3396 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3398 * Fixed the getkey command handling in the server. Send just
3399 empty OK reply to the sender if the key could not be fetched
3400 (but everything else was ok, like the key just was not available).
3401 Changed the public key parameter to optional in the protocol
3402 specs so that empty OK reply can be sent. Affected file
3405 Added a message to Irssi SILC client to tell to user if the
3406 server did not return a public key.
3408 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3410 * Fixed a channel key regeneration bug. It registered new
3411 timeout tasks exponentially until all system resources were
3412 used. Affected file silcd/server.c.
3414 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Added the SILC Document generator to the scripts/silcdoc.
3417 It can be used to generate the Toolkit Reference Manual out
3418 of the source tree. Internally it will also use the RoboDoc
3419 generator now imported in util/robodoc.
3421 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Added couple of return's in rekey protocol if error orccurred
3424 during the protocol. The execution must be terminated.
3425 Affected file silcd/protocol.c. Also, terminate the protocol
3426 always with timeout.
3428 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * The client's Client ID was created initally from the wrong
3431 nickname (it could have been in format nick@host) in the
3432 silc_server_new_client. Affected file silcd/packet_receive.c
3434 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Added some SILC_LOG_ERROR's to various error conditions
3437 if client could not be added to ID cache. Affected files
3438 silcd/packet_receive.c and silcd/server.c.
3440 * When client's sock->user_data is freed, NULL also the
3441 client->router and client->connection pointers. Added check
3442 for these pointers being NULL to various places around the
3443 code. Affected file silcd/server.c.
3445 * Added client->data.registered == TRUE checks to various
3446 places around the code to assure that unregistered client's
3447 are not handled when it is not allowed. Affected file
3450 * Added `bool registered' fields to all
3451 silc_idlist_[server|client]_get_* routines to indicate whether
3452 the fetched client needs to be registered or not. Affected
3453 file silcd/idlist.[ch].
3455 * Add your own entry as registered to the ID cache in the
3456 server. Affected file server.c.
3458 * Fixed a bug in silc_server_new_server. The SilcServer was
3459 set as the new server's context instead of SilcServerEntry.
3460 This naturally caused some weird bugs.
3462 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Do not delete the channel rekey task when adding it
3465 for in silc_server_create_channel_key.
3467 * Changed the silc_server_create_channel_key to return
3468 TRUE or FALSE to indicate the success of the channel key
3471 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Fixed MSVC++ project files and added missing files to
3474 Makefiles under win32/.
3476 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3478 * Do not add TCP_NODELAY flag if the operating system
3479 does not have it defined. Affected files are
3480 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3482 * Fixed buffer overflow from Irssi SILC Client. Affected
3483 file irssi/src/fe-common/core/themes.c.
3485 * Fixed double free in client library in the file
3486 lib/silcclient/client.c when disconnecting from server.
3488 * Applied double free patch from cras to Irssi SILC client.
3489 Affected files irssi/src/core/[modules/expandos].c
3491 * Fixed the disconnection handling to Irssi SILC Client.
3492 The application must call silc_client_close_connection
3493 in ops->connect client operation in case of failure of
3494 the connection. Affected file is
3495 irssi/src/silc/core/client_ops.c.
3497 * Do not set sock->protocol to NULL in the function
3498 silc_client_close_connection after executing the protocol's
3499 final callback since the sock might not be valid anymore.
3500 Affected file lib/silcclient/client.c.
3502 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Do not enable SILC_THREADS if the linking with libpthread
3505 did not happen. Affected file configure.in.pre.
3507 * Added notion to protocol specification that server must
3508 verify the sent authentication payload with CMODE when
3509 setting the channel founder key. Implemented it to the
3510 server. Affected file silcd/command.c.
3512 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Added _EXTRA_DIST SILC distribution variable to the
3515 distributions file. It is used to conditionally add extra
3516 files or directories to the specific distribution. Affected
3517 files ./prepare, Makefile.am.pre and distributions.
3519 Removed the `_' from the start of the distribution names.
3522 * Added README.WIN32 for instructions to compile the Toolkit
3525 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Fixed a double free in disconnection in the server. Affected
3528 file is silcd/server.c.
3530 * Fixed the lib/silcske/groups.c to work now also with GMP
3531 MP library. The string conversion did not work when using
3532 specific base and the base is indicated in the string as well.
3534 * Created win32/ directory which now includes MSVC++ specific
3535 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3536 It will appear only in the toolkit distribution
3538 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Changed the key material distribution function in case when
3541 the hash output is too short. The data is now concatenated
3542 a bit differently than it used to. Made the change to the
3543 SKE protocol specification.
3545 * Added better GMP detection to configure.in.pre. A patch
3548 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Fixed a minor bug in SKE that might cause some problem on
3551 some platforms. Affected file lib/silcske/silcske.c.
3553 * Added the cookie checking for initiator in the SKE. It checks
3554 that the responder returns the sent cookie unmodified. The
3555 affected file is lib/silcske/silcske.c. Added new SKE
3556 error type INVALID_COOKIE that can be sent during the
3557 negotiation. Fixed some memory leaks as well.
3559 * Added the "invalid cookie" error message to Irssi SILC client's
3562 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Added `task_max' field to the SilcClientParams to indicate
3565 the maximum tasks the scheduler can handle. If set to zero,
3566 default values are used. Affected file lib/silcclient/silcapi.h.
3568 * Fixed memory leaks in silc_client_close_connection. Affected
3569 file lib/silcclient/client.c.
3571 * Added silc_client_del_client_entry to client library to free
3572 all memory of given client entry. Affected file is
3573 lib/silcclient/idlist.[ch].
3575 * Added new functions silc_client_del_channel and
3576 silc_client_del_server to delete channel and server entries.
3577 Affected file lib/silcclient/[silcapi.h/idlist.c].
3579 * Removed silc_client_del_client_by_id from silcapi.h.
3581 * Fixed the INFO command to return the server's own info
3582 correctly when querying by Server ID. Affected file is
3585 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Removed the non-blocking settings in WIN32 code in the
3588 silc_sock_[read/write] and added SleepEx instead. Affected
3589 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3590 of input data is now checked with FIONREAD and ioctlsocket.
3592 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Call silc_schedule_task_del_by_context in the
3595 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3596 Affected file lib/silccore/silcprotocol.c.
3598 * Call silc_protocol_cancel for active protocols in the
3599 silc_server_close_connection if the funtion
3600 silc_server_free_sock_user_data has not been called.
3601 Affected file silcd/server.c.
3603 * Generic tasks cannot be deleted using the del_by_fd
3604 task deleting function since generic tasks does not match
3605 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3607 * Added a notion to SILCOPER help file that the SILCOPER works
3608 only on router server, not on normal server.
3610 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Added for WIN32 support for the new scheduler as well.
3613 Affected file lib/silcutil/win32/silcwin32schedule.c.
3615 * Fixed the SHA1 implementation to work on various platforms.
3617 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3619 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3620 API. It is part of the scheduler now. Everything else is
3621 as previously but some functions has changed their names.
3622 Checkout the lib/silcutil/silcschedule.h for the interface.
3623 Updated all applications to use the new interface. Affected
3624 files are lib/silcutil/silcschedule.[ch].
3626 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Found a bug in the SKE implementation. The HASH value,
3629 specified by the protocol, was not computed correctly. The
3630 public key of the responder was not added to the computation
3631 even though it is mandatory. Affected file lib/silcske/silcske.c.
3632 This unfortunately causes incompatibilities with older
3633 clients and servers.
3635 * Added WIN32 specific network init and uninit functions:
3636 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3637 the Winsock2. Affected file lib/silcutil/silcnet.h and
3638 lib/silcutil/win32/silcwin32net.c.
3640 * Set the socket always to nonblocking mode on WIN32 after
3641 reading data or writing data. Affected file is
3642 lib/silcutil/win32/silcwin32sockconn.c.
3644 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Fixed various compilation problems under WIN32. Affected
3647 files lib/silcutil/win32/silcwin32thread.c and
3648 lib/silcutil/win32/silcwin32schedule.c.
3650 * Removed all _internal.h #includes from public header
3651 files. Internal headers must never be included from
3654 Removed also the lib/silcske/payload_internal.h file.
3656 * All include files that may be needed (public and some others
3657 included by the public headers) by application developers are
3658 now copied to the ./includes directory. It does not copy any
3659 internal headers. Affected file Makefile.defines.pre and all
3660 Makefile.am's under lib/ and subdirs.
3662 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3664 * Do not change the ~/.silc directory's permissions automatically.
3665 Affected file irssi/src/silc/core/clientutil.c.
3667 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3669 * Do not cancel the protocol in silc_server_close_connection
3670 it might cause recursion. Now cancelled in the function
3671 silc_server_free_sock_user_data. Affected file silcd/server.c.
3673 * Fixed the silc_server_remove_clients_by_server to regenerate
3674 the channel keys correctly finally. Added also new function
3675 silc_server_remove_clients_channels to actually do it.
3676 Affected file silcd/server.c.
3678 * Fixed the silc_server_new_channel to not crash by giving
3679 wrong router to the new channel. Affected file is
3680 silcd/packet_receive.c.
3682 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3684 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3685 which is given as argument to the silc_client_alloc now.
3686 It can be used to configure the client and set various parameters
3687 that affect the function of the client.
3689 * The USERS command in server did not check whether the channel
3690 is private or secret. Affected file silcd/command.c.
3692 * Added new argument to the USERS command in protocol specification.
3693 The USERS command now can take the channel name as argument
3694 as well. Added support for this in client and server and
3695 updated the protocol specs.
3697 * Completed the GETKEY command in client. It can be now used
3698 to fetch also servers public key not only some clients.
3699 Affected files lib/silcclient/command[_reply].c.
3701 * Added silc_client_get_server to return server entry by the
3702 server name. Affected files lib/silcclient/silcapi.h and
3705 * Redefined the IDENTIFY command in protocol specification to be
3706 more generic. It now can be used to query information about
3707 any entity in the SILC Network, including clients, servers and
3708 channels. The query may be based either the entity's name
3709 or the ID. Added support for this in both client and server.
3711 Affected files silcd/command.c and lib/silcclient/command.c
3712 and command_reply.c.
3714 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3715 the _from_client and _from_server functions. Affected file
3718 * Added silc_client_get_channel_by_id_resolve to the file
3719 lib/silcclient/silcapi.h to resolve channel information by
3720 its ID. Added also silc_client_get_channel_by_id that
3721 does not resolve it from the server.
3723 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3725 * Added SilcServerEntry context into the client library
3726 to represent one server. The INFO command now allocates
3727 these to save the resolved server info. For now on the
3728 client library will also keep information about servers,
3729 connected and resolved with INFO.
3731 The INFO command now allocates the SilcServerEntry context
3732 and saves the server info there. The COMMAND_REPLY in
3733 the INFO now returns the parameters to application in
3734 same order as defined in the protocol specification.
3736 The entries are cached in the client->server_cache.
3738 * The INFO command is now issued after received the Client ID
3739 from the server. Affected file lib/silcclient/client.c.
3741 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3742 to the application as the mode changer might be server.
3743 It is guaranteed that NULL is not returned anymore to the
3744 application. Affected file lib/silcclient/client_notify.c.
3746 The ID Type is now also passed to the application so that
3747 it can check whether the returned entry is SilcClientEntry
3750 Added new function silc_client_get_server_by_id to return
3751 the server entry by ID. Affected files are the
3752 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3754 * Do not create the channel in the Irssi SILC Client when issuing
3755 the JOIN command but when received the sucessful JOIN command
3756 reply. Otherwise the channel might get created even though we
3757 could not join it. The Affected file is
3758 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3760 * Fixed a channel joining bug in router. The router must also
3761 check the channel modes, invite and ban lists etc. when serving
3762 the JOIN command sent by normal server. Affected file is
3763 silcd/command.c. The router now resolves the client's
3764 information from the server who sent the JOIN command if it
3765 does not know it, and processes the JOIN command only after
3768 * Changed the SilcCommandCb to take new argument; void *context2.
3769 Affected file lib/silccore/silccommand.h
3771 The second argument in the command callbacks in the server now
3772 includes the SilcServerCommandReplyContext if the command was
3773 called as pending command callback from the command reply.
3774 Otherwise it is NULL. When called as pending the status of the
3775 command reply will be checked and if it was erronous the
3776 error will be sent to the original sender of the command.
3777 This way the client always receives the error messages even
3778 though the server was actually the one who received the error
3779 when it resent the command to router, for example. Affected
3780 files silcd/command[_reply].[ch].
3782 * Fixed sending WHOWAS command's error message to client if
3783 the requested client could not be found. It was missing.
3786 * Changed the CMODE and CUMODE commands reply arguments in the
3787 protocol specification. The Channel ID is now sent in both
3788 of the commands to identify the channel. Implemented this
3789 new feature to the client and server. Affected files
3790 lib/silcclient/command_reply.c and silcd/command.c.
3792 * Made better checks for invite and ban lists in the JOIN
3793 command in server. Affected file silcd/command.c.
3795 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3797 * The server now performs the incoming host IP/DNS lookup
3798 using the silc_socket_host_lookup and thus does not block
3799 the server anymore. Affected file silcd/server.c.
3801 * Completed the multi-thread support for SILC Scheduler in
3802 the lib/silcutil/silcschedule.c.
3804 * Fixed the configure.in.pre to detect the pthread correctly
3807 * Fixed a deadlock in silc_task_queue_wakeup in the file
3808 lib/silcutil/silctask.c.
3810 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Added new function silc_schedule_wakeup that is used in
3813 multi-threaded environment to wakeup the main thread's
3814 schduler. It needs to be used when a thread adds a new task
3815 or removes a task from task queues. After waking up, the
3816 scheduler will detect the task queue changes. If threads
3817 support is not compiled in this function has no effect.
3818 Implemented the wakeup mechanism to both Unix and WIN32
3819 systems. Affected files are lib/silcutil/silcschedule.[ch],
3820 lib/silcutil/unix/silcunixschedule.c and the
3821 lib/silcutil/win32/silcwin32schedule.c.
3823 * Added new function silc_task_queue_wakeup to wakeup the
3824 scheduler by the specified task queue. Affected file
3825 lib/silcutil/silctask.[ch].
3827 * The silc_socket_host_lookup_start now wakes up the scheduler
3828 after adding the timeout task. Affected file is
3829 lib/silcutil/silcsockconn.c.
3831 * The silc_socket_host_lookup is synchronous now if the threads
3832 support is not compiled in. However, the callback is still
3833 called asyncronously through the scheduler, anyway. Affected
3834 file lib/silcutil/silcsockconn.c.
3836 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Added new function silc_socket_host_lookup to perform
3839 asynchronous IP and FQDN lookups for the socket connection.
3840 Affected files lib/silcutil/silcsockconn.[ch].
3842 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3844 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3845 that may or may not compile the mutex support in.
3847 Changed the silc_mutex_alloc interface. It allocates the
3848 mutex now to the sent pointer and returns TRUE or FALSE.
3850 Affected file lib/silcutil/silcmutex.h.
3852 * Wrote the SILC Task Queue interface to support multi-threads.
3853 Affected file lib/silcutil/silctask.[ch].
3855 * Wrote the SILC Scheduler to support multi-threads. Affected
3856 file lib/silcutil/silcschedule.c.
3858 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3860 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3861 in lib/silcutil/win32/.
3863 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Defined SILC Mutex API and SILC Thread API and implemented
3866 them for Unix. Affected files are
3867 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3868 lib/silcutil/unix/silcunixmutex.c and
3869 lib/silcutil/unix/silcunixthread.c.
3871 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3873 * Fixed the silc_server_remove_clients_by_server's channel
3874 key re-generation. The hash table handling was incorrect
3875 and would not work with many channels. Affected file is
3878 * Fixed some memory leaks around the server code.
3880 * Rewrote the silc_server_get_users_on_channel to support IPv6
3881 based Client ID's. Affected file silcd/server.c.
3883 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3884 specification. However, a separate document must be written
3885 to define the detailed signing procedure and the payload
3886 associated with the flag. Defined the flag to the
3887 lib/silccore/silcchannel.h as well.
3889 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3891 * Changed the dynamic tables to static size tables in the
3892 lib/silccrypt/silchmac.c.
3894 * Removed GCC dependencies from the code. A patch by cras.
3896 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3898 * Do not show the error "Error receiving packet bla bla"
3899 in server if it really was not an error (-2 means that reading
3900 is pending). Affected file silcd/server.c.
3902 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3904 * Fixed a possible crash in silc_server_remove_clients_by_server
3905 in silcd/server.c. Fixed there also some memory leaks.
3907 * Fixed the silc_idlist_replace_client_id. It could replace
3908 wrong key in the hash table. Affected file silcd/idlist.c.
3910 * Do not check whether there are global users on the channel
3911 if the channel->global_users is FALSE. Affected functions
3912 silc_server_remove_from_one_channel and
3913 silc_server_remove_from_channels in silcd/server.c. Also,
3914 do not check if the removed client is local as we can be
3915 sure that global client was not removed from the channel
3916 and checking for global users is not needed.
3918 * The silc_server_remove_clients_by_server now re-generates
3919 the channel keys correctly for those channels that had
3920 clients removed from them. Affected file silcd/server.c.
3922 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3924 * Found the reason of random crashes in the server. We weren't
3925 ignoring the SIGPIPE signal (which can be sent in write())
3926 and it crashed the server. Affected file silcd/silcd.c.
3928 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Assure that sock->user_data is not NULL in the function
3931 silc_server_packet_send in silcd/packet_send.c.
3933 * Disconnect the remote connection if it could not be added
3934 to any ID lists in the server. The affected file is
3937 * Check in silc_server_packet_send[_real/dest] that the
3938 socket is not disconnecting and ignore the data if it is.
3939 Affected file silcd/packet_send.c.
3941 * Define inline to __inline on native WIN32 compilation.
3942 Affected file includes/silcwin32.h.
3944 * Added some explicit type casts for inline code since MSVC
3945 require them. Affected files lib/silcutil/silcbuffer.h,
3946 lib/trq/silcdlist.h and lib/trq/silclist.h.
3948 * Print warning in log files from now on if the packet
3949 decryption fails. Affected file silcd/server.c.
3951 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Changed the `say' client operation's interface to accept
3954 new `type' argument to indicate the type of the message sent
3955 by the library. The application may filter the library's
3956 messages according the type. The affected file is the
3957 lib/silcclient/silcapi.h.
3959 * Added two new functions to lib/silcclient/silcapi.h:
3960 silc_client_del_client and silc_client_del_client_by_id.
3961 Affected file lib/silcclient/idlist.c.
3963 * Moved the clientincludes.h from includes/ to silc/ and
3964 serverincludes.h from includes/ to silcd/.
3966 * The modes for the CMODE and CUMODE are now passed as
3967 uint32 for application with COMMAND_REPLY. The affected
3968 file is lib/silcclient/command_reply.c.
3970 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3972 * /WHOIS without arguments shows client's own information.
3973 Affected file lib/silcclient/command.c.
3975 * Changed PING to not accept any arguments. The specs
3976 says that client can ping only the connected server so
3977 requiring an argument is not needed. Affected file is
3978 lib/silcclient/command.c.
3980 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3982 * Fixed a fatal bug in private message sending and reception
3983 encryption and decryption when using private message keys.
3984 The implementation was incorrect and did not follow the
3985 specification. It causd that some of the message were
3986 lost since it did not use the sending and receiving keys
3987 as the protocol suggests. This has been fixed and will cause
3988 incompatibilities with older clients when sending private
3989 message encrypted with private message keys. Affected files
3990 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3991 and various other in Irssi SILC Client.
3993 Added `responder' boolean argument to the functions
3994 silc_client_add_private_message_key[_ske] to indicate when
3995 the key is added as responder or initiator of the key
3998 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Removed the silc_ske_check_version function and created
4001 a SilcSKECheckVersion callback. Added also a function
4002 silc_ske_set_callbacks that is now used to set all SKE
4003 callbacks. The callback functions are not given to
4004 the SKE functions anymore, but this function is used to
4007 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4009 * Added `silc_version' argument to the silc_client_alloc
4010 to define the version of the application for the library.
4011 The library will use the version string to compare it
4012 against the remote host's (usually a server) version
4013 string. Affected file lib/silcclient/silcapi.h
4015 * Added the KE protocol context to Key Agreement context
4016 in client library so that we can abort the SKE if it
4017 is in process when we get timeout. Affected file is
4018 lib/silcclient/client_keyagr.c.
4020 * Do not resolve the client ID forever if it returns in the
4021 first time that such client does not exist. This was done
4022 for example with private message. Affected file is
4023 lib/silcclient/client_prvmsg.c.
4025 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4027 * Do not add regex.h for WIN32. The affected file
4028 includes/silcincludes.h.
4030 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4031 not work yet 100%. It generates the DLL's automatically
4032 when compiling with --with-win32 under cygwin.
4034 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4036 * lib/contrib/regex.c is not compiled on WIN32.
4038 * Added silc_net_get_socket_opt function to the
4039 lib/silcutil/silcnet.h.
4041 * Added includes/silcwin32.h for WIN32 specific includes
4044 * Do not use ptime structure or any of the posix process
4045 functions on WIN32 in lib/silccrypt/silrng.c.
4047 * Added silc_gettimeofday to provide generic function
4048 for struct timeval on all platforms. Added the function
4049 to lib/silcutil/silcutil.h.
4051 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4053 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4054 library as they clearly belong there. As a plus side we
4055 can make the actual socket connection routines platform
4058 Added also new generic function silc_socket_read and
4059 silc_socket_write (that used to be silc_packet_[read/write].
4060 The implementation of these are platform specific.
4062 * Added WIN32 specific routines of silc_socket_[read/write]
4063 to lib/silcutil/win32/silcwin32sockconn.c.
4065 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Added preliminary support for native WIN32 compilation under
4068 cygwin (using the -mno-cygwin option for GCC) to the
4069 ./configure.in.pre. The --with-win32 now prepares the
4070 compilation for native WIN32.
4072 * Rewrote the SILC Scheduler interface in the file
4073 lib/silcutil/silcschedule.h. The scheduler is now context
4074 based and does not have anymore any global static scheduler.
4075 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4076 and created lib/silcutil/win32 directory for WIN32 based
4079 * Added Unix specific network routines to the
4080 lib/silcutil/unix/silcunixnet.c and the old
4081 lib/silcutil/silcnet.c includes now only generic routines.
4083 Added WIN32 specific network routines to the
4084 lib/silcutil/win32/silcwin32net.c.
4086 * Added Unix specific utility functions from the
4087 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4089 * Added WIN32 SILC Scheduler to the file
4090 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4093 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4095 * Do not handle JOIN notify in the server if the target client
4096 is not registered (idata->registered == FALSE). The affected
4097 file is silcd/packet_receive.c.
4099 * Update the nickrec->founder in event_cumode in the Irssi SILC
4100 client. Affected file irssi/src/silc/core/silc-channels.c.
4102 * Fixed the CUMODE_CHANGE notify handling in the server when
4103 server and router are announcing their clients on channels.
4104 Now the mode changes are saved and notified correctly. The
4105 affected file is /silcd/packet_receive.c.
4107 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4108 They really did not replace the cache entry in the ID Cache.
4109 Now they do that. Affected file silcd/idlist.c.
4111 * Fixed the KICK notify handling in the Irssi SILC client to
4112 update the channel records so that the kicked client does not
4113 appear to be on the channel. The affected file is
4114 irssi/src/silc/core/silc-channels.c.
4116 * Always update the conn->current_channel when executing command
4117 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4119 * Fixed the KILL notify handling in Irssi SILC client to remove
4120 the killed client on all channels.
4122 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Fixed the silc_parse_command_line to remove extra spaces
4125 from the start and end of the arguments. Affected file is
4126 lib/silcutil/silcutil.c.
4128 * Cancel and free any active protocol in the function
4129 silc_server_close_connection. Affected file silcd/server.c.
4131 * Cancel and free any active protocol in the function
4132 silc_client_close_connction. Affected file is
4133 lib/silcclient/client.c.
4135 * Do not execute the KILL command for clients that are in
4136 history (ie. they are not in the network). Affected file is
4139 * Fixed KILL notify handling, client does not crash anymore.
4140 Affected file irssi/src/silc/core/silc-channels.c.
4142 * Reduced the default packet buffer size from 2048 to 1024 in
4143 lib/silccore/silcpacket.c.
4145 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4146 counter to the SKE context that is incresed when the SKE library
4147 performs async operation outside the library. If the outside
4148 process frees the SKE context and FREED status will be set
4149 and the library will detect after the sync operation that the
4150 libary is freed. The affected files are
4151 lib/silcske/silcske[_status].[ch].
4153 * Resolve the client entry information in the function
4154 silc_client_channel_message to assure that NULL pointer is not
4155 passed as client entry to the application. */
4157 * Fixed the task timeout calculation to assure that there is
4158 never negative timeouts. The affected file is
4159 lib/silcutil/silcschedule.c.
4161 * Fixed the channel user mode notification sending in server.
4162 It was sent point-to-point to the router (or to server by router)
4163 but it needs to be destined to a channel. The routines now
4164 supports sending the channel user mode notifys to the channels
4165 when announcing clients and channels. Affected files are
4166 silcd/server.c and silcd/packet_receive.c.
4168 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4169 It did not actually replace the old channel entry in the cache.
4170 Affected file lib/silcclient/client_notify.c.
4172 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Fixed a possible crash in silc_packet_send_prepare. It now
4175 assures always that there is enough space in the buffer and
4176 at the tail area of the buffer (for MAC).
4178 Fixed the inbound buffer reallocation in silc_packet_read.
4179 It was old code and did not handle the reallocation correctly.
4182 The affected file is lib/silccore/silcpacket.c.
4184 * Fixed buffer overflow in silc_parse_nickname in the file
4185 lib/silcutil/silcutil.c.
4187 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * make install generates new server keys only if there is not
4192 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4195 Added check that if the NOREPLY is set then we will not send
4196 the away message. This avoids infinite loop of away messages
4197 if both clients are away. The affected file is
4198 lib/silcclient/client_prvmsg.c.
4200 * Fixed client crash if /NICK was given without arguments.
4201 Affected file lib/silcclient/command.c.
4203 * Server does not send the invite list in INVITE command back
4204 to the client if the list was not altered. Added this notion
4205 to the protocol spec as well. Affected file silcd/command.c.
4207 Fixed possible crash in INVITE command by checking the
4208 value of silc_server_get_client_route command.
4210 * Fixed the INVITE notify type handling. The arguments are now
4211 taken in correct order and client does not crash. The affected
4212 file is irssi/src/silc/core/silc-channels.c.
4214 Removed the "Inviting xxx to channel" message from the
4215 client library away and let the application handle it.
4216 Affected file lib/silcclient/command.c. Added that message
4217 to Irssi SILC client's message formats.
4219 * Fixed CMODE command crash in client. It now checks the
4220 amount of arguments correctly and does not crash. The affected
4221 file is lib/silcclient/command.c.
4223 * Do not create new channel automatically in silc_channels_join
4224 but check whether the channel by that name already exists.
4225 Affected file irssi/silc/core/silc-channels.c.
4227 * Do not send the SERVER_SIGNOFF to router if the disconnected
4228 entity was the router. Affected file silcd/server.c.
4230 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4231 SILC client as it was missing from there.
4233 Added the handling of the KICK notify to the Irssi SILC client
4234 as it was missing. Added "you have been kicked" message to
4235 Irssi SILC client's message modules formats.
4237 Added the handing of the KILL notify to the Irssi SILC client
4238 as it was missing. Added the kill message module formats
4241 The affected file is irssi/src/silc/core/silc-channels.c.
4243 * The router did not save the channel mode the server announced.
4244 Affected file silcd/packet_receive.c.
4246 * Fixed a possible crash in INFO command in server. If the
4247 server did not provide the server info it crashed. Affected
4248 file silcd/command.c.
4250 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Fixed the GETKEY command in the server to check also the
4253 global list. Otherwise the GETKEY would not work correctly
4254 in normal SILC server. Affected file silcd/command.c.
4256 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Fixed GETKEY crash, it crashed if the command did not succseed.
4260 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4263 is now real and not just an macro interface to GMP.
4265 Removed the entire GMP from the source tree and imported new
4266 NSS MPI library instead. Reason for removing GMP is that it is
4267 extremely large and compiles extremely slow. The NSS MPI
4268 is only a few files and compiles in less than 10 seconds.
4269 The speed is also about the same as GMP. The MPI is imported
4270 to lib/silcmath/mpi.
4272 If the system has GMP installed we will still use the GMP.
4273 If it is not then the NSS MPI will be compiled.
4275 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4277 * Merged a long nickname (127 characters long) crash bugfix from
4278 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4280 * Merged a freed memory reference bugfix from Irssi CVS tree.
4281 Affected file irssi/src/core/commands.c.
4283 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added the server's public key sving and verification to the
4286 server when performing the SKE. This was missing and the
4287 remote server's (or router's) public key was accepted without
4288 checking whether we have it previously or trust it at all.
4289 Affected file silcd/protocol.c.
4291 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4293 * Check in the silc_server_timeout_remote if protocol is active
4294 and make sure that the protocol's final callback is called so
4295 that all memory if freed. Affected file silcd/server.c.
4297 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * silc_server_whois_send_reply crashed the server if the nickname
4300 was 127 characters long. Affected file silcd/command.c.
4302 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4304 * Added sanity check to the silc_server_new_client. If the hostname
4305 is provided inside username then check that the provided hostname
4306 really is the same as the resolved one. If the hostname was not
4307 resolved then check it from the public key. Affected file is
4308 silcd/packet_receive.c.
4310 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4311 if the server disconnected us and the connection is not valid
4312 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4314 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4315 the library to the lib/silcutil/silcutil.[ch].
4317 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Close log file after open. Affected file
4320 lib/silcutil/silclog.c.
4322 * Check whether sock == NULL in silc_client_send_packet and return
4323 if it is. Affected file lib/silcclient/silcclient.c.
4325 * Check rec->entry == NULL in the Irssi SILC Client before
4326 sending the channel message. Affecte file is
4327 irssi/src/silc/core/silc-servers.c.
4329 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Merged a splitted window bugfix from Irssi CVS tree. The
4332 affected file is irssi/src/fe-text/textbuffer-view.c.
4334 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4335 It did not print nickname.
4337 * Improved the distributions system a bit.
4339 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4342 irssi/src/fe-text/gui-window.c.
4344 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4345 to in-active server. The affected file is
4346 irssi/src/silc/core/client_ops.c.
4348 * Resolve the client in USERS command reply if the entry does
4349 not have username resolved. The affected file is
4350 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4351 command to WHOIS command to really resolve stuff. The USERS
4352 is not used any more in any critical section so WHOIS can
4353 be used even though it might be slower than IDENTIFY.
4355 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4358 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Changed the protocol API a bit more consistent in the
4361 lib/silccore/silcprotocol.[ch].
4363 * Changed the following headers to ROBODoc format:
4365 lib/silccore/silcpayload.h
4366 lib/silccore/silcprotocol.h
4367 lib/silccore/silcsockconn.h
4369 All core library headers are now formatted.
4371 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Fixed a bug in Irssi SILC client; do not show that you are
4374 server/router operator if you really are not. Affected file is
4375 irssi/src/silc/core/client_ops.c.
4377 * Renamed silc_command_free_payload to silc_command_payload_free.
4378 Affected file lib/silccore/silccommand.h
4380 * Added silcmath.h to include the prototoypes of various routines
4381 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4384 * Changed the following headers to ROBODoc format:
4386 lib/silccore/silcchannel.h
4387 lib/silccore/silccommand.h
4388 lib/silccore/silcid.h
4389 lib/silccore/silcidcache.h
4390 lib/silccore/silcmode.h
4391 lib/silccore/silcnotify.h
4392 lib/silccore/silcpacket.h
4393 lib/silcmath/silcmath.h
4395 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added checking to the server code not to start the server if
4398 ciphers and stuff are not configured properly. Affected files
4399 silcd/serverconfig.[h] and silcd/server.c.
4401 * Changed the layout of the header files of the public interfaces
4402 in the SILC libraries. The new layout supports ROBODoc
4403 documentation tool (and some others) so that it is easy to create
4404 a library reference manual. All the other headers and source
4405 code must still follow the CodingStyle document. Also source
4406 code must not include these ROBODoc stuffs, only the headers.
4407 Furthermore, all public interface headers must now be named
4408 by using `silc' prefix, example: silcapi.h, silccipher.h.
4409 Some files were renamed due to this. All the other headers
4410 must not be used as public interfaces. I will update the
4411 CodingStyle document later. Changed following headers, so far:
4413 lib/silcclient/silcapi.h
4414 lib/silccore/silcauth.h
4415 lib/silccore/silcprivate.h
4416 lib/silccrypt/silcdh.h
4418 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Removed silc_client_packet_send_flush from the client library
4423 as it is not needed. Affected file lib/silcclient/client.[ch].
4425 * Added printing of message of unresolved authentication method
4426 to the Irssi SILC client. Added it to the module formats.
4427 Removed the same message from the client library.
4429 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Added new distribution feature, DISTLABEL. Every distribution
4432 can define own preprocessor label that can be used in the
4433 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4434 file distributions, acconfig.h.pre and prepare.
4436 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Added Makefile.defines_int to include the actual definitions
4439 for Makefile.defines.in. Tested the new distribution system,
4440 created distributions and tested installation.
4442 * Added AWAY message printing to the Irssi SILC client. Added
4443 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4445 * Added SCONNECT command to call the SILC's CONNECT command.
4446 Cannot use CONNECT directly since Irssi uses that internally.
4447 Affected file irssi/src/silc/core/silc-servers.c.
4449 Added ACTION local command. It is same as ME command but takes
4450 the channel as mandatory argument.
4452 Rewrote some of the Irssi's help files to suite for SILC
4455 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Added Makefile.defines[.in] that should for now on be included
4458 in all Makefile.am file in the source tree. That file includes
4459 all common compilation definitions for SILC source tree.
4461 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Minor changes to the ./prepare script to change the package
4464 name according the distribution name to the configure.in.
4466 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Created new distribution system. Added file `distributions'
4469 that defines all the distributions that can be created out of
4470 the SILC source tree. The ./prepare script now reads that
4471 file to determine how to prepare the distributions. The
4472 first argument to the ./prepare is the name of the distribution
4473 and second is the version of the distribution. If given
4474 without arguments it creates the default (toolkit) distribution
4475 with the default version (defined in ./prepare).
4477 All Makefile.am files that are subject to the distributions
4478 are now named as Makefile.am.pre. These are ./Makefile.am
4479 and lib/Makefile.am. Others may be changed later.
4481 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Added invite list, ban list, some key management and connection
4484 error message printing to module formats in the Irssi SILC client.
4486 * Added new silc_client_set_away_message to set the away message
4487 that is back to the person who sent private message. The
4488 affected file lib/silcclient/silcapi.h and the
4489 lib/silcclient/client_prvmsg.c.
4491 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4493 * Fixed the private message sending in the Irssi SILC client,
4494 added local command KEY to the Irssi SILC client.
4496 Added key management and key agreement message formats to the
4497 irssi/src/fe-common/silc/module-formats.[ch].
4499 Added USERS (alias WHO) printing, server/router operator
4500 indication and LIST command printing to the module formats.
4502 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Fixed channel joining notify handling, cumode notify handling
4505 from Irssi SILC client.
4507 * Added SILC specific module-formats to the Irssi SILC client so
4508 that SILC specific message hilighting, colors etc is possible.
4509 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4511 Added channel mode, channel user mode, actions, notices,
4512 whois and whowas printing to the the module-formats.c.
4514 * Fixed a bug in channel deletion in the server. The channel
4515 is not left to the cache even if the channel founder auth mode
4516 is set when there are no users anymore on the channel. Affected
4517 file silcd/server.c.
4519 * The silc_net_localhost now resolves the entire hostname including
4520 the domain name. Affected file lib/silcutil/silcnet.c.
4522 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Changed the ask_passphrase client operation to be ascynchronous.
4525 It has now a completion callback and a context that the
4526 application must call after it has got the passphrase from
4527 the user. Affected files lib/silcclient/silcapi.h,
4528 lib/silcclient/protocol.c, lib/silcclient/command.c and
4531 Added SilcAskPassphrase callback that the application calls
4532 to deliver the passphrase to the library.
4534 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4535 The public key verification and especially a certificate
4536 verification is asynchronous procedure.
4538 Added new SILC_SKE_STATUS_PENDING status to indicate the
4539 request is pending and a callback will be called to finalize
4542 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4543 indicate that remote end did not send its public key (or
4544 certificate), even though we require it. Added check for this
4545 condition in the SKE. This was a security bug, now fixed.
4547 Defined new SilcSKEVerifyCbCompletion callback that is called
4548 when the verification process is completed.
4550 The affected files lib/silcske/silcske_status.h and
4551 lib/silcske/silcske.[ch].
4553 * Changed the verify_public_key client operation to be async
4554 as well. Defined SilcVerifyPublicKey callback that is used to
4555 indicate the success of the public key verification process.
4557 Changed the server and client to use the new async client
4560 * Changed the Irssi SILC client's internal scheduler to be called
4561 twice as many times as it used to be. As a result the client
4562 should be a bit faster now. Affected file is
4563 irssi/src/silc/core/silc-core.c.
4565 * Added support to Irssi SILC client of asynchronous public key
4566 verification and passphrase inquiry. Affected file is
4567 irssi/src/silc/core/silc-core.c.
4569 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4571 * Do not say "You have left channel %s" in client library.
4572 Moved it to the application. Affected files are
4573 lib/silcclient/command.c and silc/client_ops.c.
4575 * Fixed silc_client_get_clients. Command context was not
4576 duplicated and was freed memory in the callback. Affected
4577 file lib/silcclient/idlist.c.
4579 * Do not say "you are now talking..." on JOIN command in the
4580 client library. The appliation must handle it.
4582 * Do not say ".. changed topic to" in command reply in the
4583 client libary. The application must handle it.
4585 * Fixed TOPIC command sending in the client library.
4587 * Fixed a memory leak in silc_client_command_free in the file
4588 lib/silcclient/command.c.
4590 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Imported a modified version of Irssi client to the source tree.
4593 The Irssi will be used to create a new client called
4594 Irssi SILC. Imported to irssi/.
4596 Added silc_core_init_finish function to the Irssi. Affected
4597 file irssi/configure.in.
4599 A lot changes in the Makefile.ams around the irssi tree.
4601 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4603 * Do not rehash if the new size is same as the old size of the
4604 hash table, in the silc_hash_table_rehash*. The affected file
4605 lib/silcutil/silchashtable.c.
4607 * Replaced hash_table_del_by_context calls from the server
4608 (when channel->user_list and client->channels) to the
4609 hash_table_del as it is sufficient and faster.
4611 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Added silc_hash_table_list, silc_hash_table_get and the
4614 SilcHashTableList structure to provide an alternative way to
4615 traverse the hash table. The affected files are
4616 lib/silcutil/silchashtable.[ch].
4618 * Changed the server's idlist routines to use the hash table
4619 routines to optimize the code.
4621 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Replaced the client entry's `channel' list and channel entry's
4624 `user_list' list to hash tables for optimized lookup. Changed
4625 the code to use the hash table interface around the code.
4626 Affected file lib/silcd/idlist.[ch].
4628 * Added `auto_rehash' boolean argument to the function
4629 silc_hash_table_alloc to indicate whether the hash table should
4630 auto-rehash when it thinks is appropriate time. It will
4631 increase the hash table size if the there is twice as much
4632 entries in the table than the size of the table, and will
4633 decrease the size if there are twice as less entries than
4634 the size of the table.
4636 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4640 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * silc_idcache_purge_by_context deletes the entry now by context
4643 as it is supposed to do. Affected file lib/silccore/idcache.c.
4645 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4646 client is not anymore valid (WHOWAS givens the info) and not
4647 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4649 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Removed the `data' and `data_len' arguments from the ID Cache
4652 interfaces and added `name' argument. ID Cache does not handle
4653 anymore the binary data only a names associated with given ID.
4655 * When hashing a Client ID with silc_hash_id the entire ID is
4656 not hashed anymore, instead only the hash of the Client ID is
4657 hashed. This way we can access the Client ID from the cache
4658 with Client ID but with the hash of the ID (which is a hash of
4659 the nickname) as well without any difference in performance.
4661 Added also silc_idcache_find_by_id_one_ext to do one on one
4662 searching when we have the actual ID. Added also function
4663 silc_hash_client_id_compare. The affected files are
4664 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4666 * When hashing the name associated with a ID it is always done
4667 in lowercase. This way we can access the cache without worrying
4668 about case-sensitivity, even though, for example nicknames are
4671 * Fixed a bug in server with channel message sending. It put
4672 wrong ID type as destination ID. The affected file
4673 silcd/packet_send.c.
4675 * silc_idcache_del_by_context now deletes from all hash tables
4676 by context. Affected file lib/silccore/idcache.c.
4678 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4680 * Changed the client library to use the new ID Cache interface.
4681 Changes around the source tree.
4683 * Added silc_hash_table_rehash_ext to rehash with specific
4684 hash function. Affected file lib/silcutil/silchashtable.[ch].
4686 * Added silc_hash_string_compare to compare two strings in the
4687 hash table. Affected file lib/silcutil/silcutil.[ch].
4689 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4691 * Added new function silc_idcache_del_by_context into the
4692 lib/silccore/idcache.[ch].
4694 * Changed the server's ID list routines to use the new ID Cache
4695 interface. Changes around the source tree.
4697 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4699 * Added silc_hash_table_del[_by_context]_ext functions in to the
4700 lib/silcutil/silchashtable.[ch].
4702 Removed silc_hash_table_find_all* routines and added new
4703 silc_hash_table_find_foreach to replace them.
4705 Added silc_hash_table_replace_ext function as extended
4706 replacing function. Separated the simple hash table interface
4707 from the extended hash table interface in the file
4708 lib/silcutil/silchashtable.h.
4710 * Fixed minor bugs and changed it to use some of the new
4711 hash table functions in lib/silccore/idcache.c
4713 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Added new function silc_hash_table_find_all to return all keys
4716 in the hash table by the specified key. As the hash table is
4717 collision resistant it also makes it possible to have several
4718 duplicate keys in the hash table. This function may be used to
4719 find all of the keys from the hash.
4721 Added user_context arguments to the SilcHashFunction,
4722 SilcHashCompare and SilcHashDestructor to deliver user specified
4725 Added new fuctions silc_hash_table_find[_all]_ext to do
4726 extended lookup with specified hash and compare functions and
4727 specified user contexts.
4729 Added new function silc_hash_table_add_ext to add the key
4730 with specified hash function and user context.
4732 Added new function silc_hash_table_foreach to traverse all
4733 entrys in the hash table. Added SilcHashForeach callback
4736 Added new function silc_hash_table_del_by_context to delete
4737 the entry only if the context associated with the key matches.
4739 Affected files are lib/silcutil/silchashtable.[ch].
4741 * Removed silc_hash_[server/client/channel]_id and added just
4742 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4743 silc_hash_id_compare to compare two ID's using as the hash table
4744 comparison function. Added also silc_hash_data to hash
4745 binary data and silc_hash_data_compare to compare it.
4747 * Removed silc_idlist_find_client_by_hash as it is not needed
4748 anymore. Affected file silcd/idlist.[ch].
4750 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4751 to use internally the SilcHashTable. The new ID Cache is a lot
4752 faster than the old one. Some of the ID Cache interface was also
4753 rewritten and obsolete and stupid functions were removed.
4755 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Added entry_count field to the SilcHashTable to keep the number
4758 of the entries in the table. Implemented the function
4759 silc_hash_table_rehash. Added new function
4760 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4762 Fixed a minor bug in silc_hash_table_free.
4764 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4765 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4766 into the lib/silcutil/silcutil.[ch].
4768 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Implemented a collision resistant hash table into the
4771 lib/silcutil/silchashtable[ch]. See the header and the source
4772 for the SilcHashTable API.
4774 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4776 * Merged dotconf version 1.0.2 into lib/dotconf.
4778 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Do not compile anything in lib/silcsim/* if the SIM support
4781 is not enabled. The tree should now compile without problems
4784 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4786 * Compiled the SILC under cygwin. Compiled and tested briefly
4787 without problems. More tests needed. The SIMs didn't compile
4790 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4792 * Fixed possible crash in silc_get_username in the
4793 lib/silcutil/silcutil.c.
4795 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Fixed a va_arg in silc/client_ops.c.
4799 * Oops, RC5 routines were named AES and caused some problems
4800 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4802 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Added new SilcIDIP structure into the lib/silccore/id.h and
4805 replaced the old `ip' fields from all SILC ID's to that type.
4806 This is a step towards IPv6 support.
4808 The silc_id_get_len takes now the ID as an extra argument.
4809 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4810 both IPv4 and IPv6 based ID's.
4812 The affected files are lib/silccore/id.[ch] and other files
4813 around the tree using these routines.
4815 * Removed the ID length arguments in server from various
4816 silc_server_send_notify_* routines -> they are not needed
4819 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Fixed memory leak in silc_encode_pem_file in the file
4822 lib/silcutil/silcutil.c.
4824 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Check minor version as well in the SKE. Affected files are
4827 silcd/protocol.c and lib/silcclient/protocol.c.
4829 * Added --identifier option to the server so that an identifier
4830 can be when creating the public key for the server. Affected
4831 file is silcd/silcd.c.
4833 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4834 lib/silccrypt/silcpkcs.c.
4836 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Register default ciphers and stuff when using -C option with
4839 the server. Affected file sildc/silcd.c.
4841 * Put back the servers public key filename format, it is better
4842 than the new one. For now, the client keys are saved with the
4843 new filename format. The affected file silc/client_ops.c.
4845 * Implemented the Cipher API for the rest of the ciphers that
4846 did not implement it or implemented it the wrong way.
4848 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Register default ciphers and stuff when using the -S option
4851 in the client. Affected file silc/silc.c. Same also when
4852 creating new key pair with -C option.
4854 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4856 * Fixed the silc_verify_public_key client operation function to
4857 save the public keys differently. The fingerprint is now
4858 used as filename and not the hostname. This way also the
4859 client keys are saved uniquely and not with hostnames. The
4860 affected file is silc/client_ops.c.
4862 * Trimmed the silc_hash_fingerprint function to remove extra
4863 whitespaces from the end of the fingerprint. The affected
4864 file is lib/silccrypt/silchash.c.
4868 * Added silc_cipher_register_default function to register all
4869 default ciphers. It can be used when configuration files
4870 does not exist and the application does not want any specific
4871 ciphers in any specific order.
4873 The SilcDList is now used as silc_cipher_list dynamically
4874 allocated cipher list. Removed the static list all together
4875 and now all ciphers must be allocated to the dynamic list.
4876 The silc_cipher_alloc routine was changed to check only the
4879 All silc_cipher_* routines that used to return int returns
4882 The affected files lib/silccrypt/silccrypt.[ch].
4884 * The same thing was done to silc_hash_* as for silc_cipher_*
4885 routines. Affected files lib/silccrypt/silchash.[ch].
4887 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4888 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4889 Added also silc_pkcs_[un]register[_default] functions.
4890 Removed the data_context from the PKCS API.
4892 * Added silc_hmac_register_default function to register default
4893 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4894 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4895 to unregister all hmacs at once.
4897 * Register the default ciphers, hash functions, PKCSs and HMACs
4898 if client's configuration file does not exist. The affected
4901 * The client did not load the hash functions from the SIM
4902 modules at all. Added support for this. Affected file is
4903 silc/clientconfig.c.
4905 * When decoding public key with silc_pkcs_public_key_decode, check
4906 the supported algorithm only if PKCS are registered. Affected
4907 file lib/silccrypt/silcpkcs.c. The same was done with the
4908 silc_pkcs_private_key_decode.
4910 * Fixed the SILC List routines to keep the list always in order.
4911 It used to change the list's order when traversing the list but
4912 not it preserves the order. Affected file lib/trq/silclist.h.
4914 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added the client library to use the SilcSocketConnection's
4917 reference counter (by silc_socket_dup) to prevent the bug that
4918 the socket object may be freed underneath async operation.
4920 * The name resolv library checking fixes in the configure.in.pre.
4923 * Created new version of the protocol drafts for future
4924 development. The -03 drafts are the ones that will be changed
4925 in the trunk now and the -02 will remain as they are.
4927 * Send list of CUMODE notifys to the router when announcing
4928 the channel users to the router. Affected file silcd/server.c.
4929 If the router receiving channel founder CUMODE for a channel
4930 that already has channel founder it will send CUMODE notify
4931 to the sender to remove the channel founder rights from the
4932 announced client. Affected file silcd/packet_receive.c.
4934 * The CUMODE notify may now use Server ID as well as the entity
4935 who changes the mode. Updated protocool specs.
4937 * Updated INSTALL and README files.
4939 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4941 * New web pages in the http://silc.pspt.fi. The pages was
4946 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Implemented the [DenyConnectin] config section in the server.
4949 Added silc_server_config_denied_conn to check whether incoming
4950 connection is denied. Affected file silcd/serverconfig.[ch].
4952 * Do not check the ports when checking the incoming configuration
4953 data if the port is 0, meaning any. Affected file is
4954 silcd/serverconfig.c.
4956 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Fixed buffer overflow in silc_string_compare in the file
4959 lib/silcutil/silcutil.c.
4961 * Fixed double free in silc_server_command_leave in the file
4964 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4966 * Fixed the version checking in the server. Affected file is
4969 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4971 * Fixed the configuration data fetching when accepting new
4972 connections in the server. Affected file silcd/server.c.
4974 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4976 * Added `sender_entry' argument to the function
4977 silc_server_packet_relay_to_channel so that we can check
4978 whether some destination actually belongs to the same route
4979 the sender belongs (ie, we must not resend the packet to the
4980 sender). Affected file silcd/packet_send.[ch].
4982 * Added `servername' field to the SilcClientEntry in the server
4983 to hold the name of the server where client is from. Affected
4984 file is silcd/idlist.h.
4986 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Moved the channel message encrypting in the router betwen
4989 router connections from silc_server_channel_message to the
4990 silc_server_packet_relay_to_channel since we want to check
4991 whether we have anybody channel before encrypting anything.
4992 Affected files silcd/packet_[receive/send].c.
4994 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4996 * Fixed the [AdminConnection] server config section to support
4997 multiple entries. Affected file silcd/serverconfig.c.
4999 * Added support into the server to check the validity of the
5000 incoming connection before executing any KE or authentication
5003 * The connection configuration is now saved to the KE and
5004 connection auth protocol contexts and not fetched anymore in
5005 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5007 * The local hosts listenning address and port is also resolved
5008 now when starting the server. We want to have the socket object
5009 to include the real address and port for the listener. Added
5010 new function silc_net_check_local_by_sock into the files
5011 lib/silcutil/silcnet.[ch].
5013 * Fixed a broadcast bug in server -> do not broadcast if we
5016 * Fixed a routing bug. Do not route broadcast packets ever.
5017 Broadcast packets must be processed always and not routed since
5018 they may be destined to some other host than yourself and thus
5019 would get routed without no good reason. Affected file is
5022 * Added function silc_server_config_is_primary_route to check
5023 whether primary router connection has been configured (a router
5024 configuration that we are initiating). If there is not, we
5025 will assume that there is only two routers in the SILC network
5026 and we will use the incoming router connection as our primary
5027 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5029 * Changed the order of the broadcasting. Broadcast _after_ the
5030 packet has been processed not before. Affected file is
5033 * Fixed a [ClientConnection] parsing bug. The port was never
5034 parsed correctly thus resulting to port 0. Affected file
5035 silcd/serverconfig.c.
5037 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5038 argument and did not set the broadcast packet flag. Affected
5039 file silcd/packet_send.c. Fixed same bug in the function
5040 silc_server_send_notify as well.
5042 * If we receive NEW_ID packet for our own ID in the server, ignore
5045 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Removed the nickname from the Private Message Payload.
5050 Updated the code and the protocol specs.
5052 * Updated protocol specs for submitting to the IETF.
5054 * Tweaked the Random Number Generator a bit. Affected file
5055 lib/silccrypt/silcrng.c. Exported a new function
5056 silc_rng_[global]_add_noise which can be used to add more
5059 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Do not parse packets with different timeout when protocol
5062 is active -> may cause problem with rekey. Affected file
5065 * When server receives signoff notify it must not create
5066 new channel key if the client is on any channels since the
5067 sender of the signoff notify will create it.
5069 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Added printing of error messages during SKE protocol from the
5072 failure packet sent by server during SKE. Affected file
5075 * Removed the client's failure_callback handling with timeout
5076 and handle it immediately when received.
5078 * The SKE library returned wrong type in SUCCESS and FAILURE
5079 packets. They must be 32 bit MSB not 16 bit MSB.
5081 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Ok, rewrote the logic of the re-key and now it seems to work.
5084 I tested it on high traffic with frequent re-keys without
5085 problems. Added hmac_receive (and renamed hmac to hmac_send)
5086 in SilcClientConnection in lib/silcclient/client.h and
5087 in SilcIDListData in silcd/idlist.h. Also, removed the
5088 SilcPacketParserContext's cipher and hmac fields as they are
5089 not needed anymore and actually caused some problems when
5090 the ciphers and hmac's changed underneath the packet parser.
5092 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * If re-key protocol is active then process the incoming packets
5095 synchronously since we must assure that icoming packets encrypted
5096 with the old key is processed before the new keys is set to
5097 use. This is true other packets than for REKEY packets.
5098 Affected file silcd/server.c. The same was done to client library
5099 as well, affected file lib/silcclient/client.c.
5101 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Fixed bug in client and server to accept the force send if
5104 the packet is send from silc_[server/client]_packet_process
5105 function. Otherwise the packets are never delivered, oops.
5107 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Disable force sending of packets when REKEY protocol is active.
5110 We must assure that no packet is sent directly when rekey is
5111 performed. All packets must be sent through packet queue.
5112 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5113 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5114 function is silc_[server/client]_packet_send_real to check
5117 * Replaced the SIM paths from example config files to
5118 /usr/local/modules. Also, make install creates now
5119 /usr/local/silc/logs directory to hold all the SILC server
5122 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Made the configure.in.pre work on Solaris. Patch by salo.
5126 * Made all ciphers compatible with non-x86 machines. Defined
5127 CBC mode macros into lib/silccrypt/ciphers_def.h.
5129 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Fixed the make install.
5133 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * When MAC computation fails the silc_packet_decrypt returned 0
5136 even though it was supposed to return -1. Fixed this. The
5137 affected file is lib/silccore/silcpacket.c.
5139 * Do not replace the config files in /etc/silc (in make install)
5140 if they already exist. Affected file ./Makefile.am.
5142 * Do not send re-key packets immediately but through packet queue.
5143 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5145 * Changed silc_net_check_host_by_sock to return FALSE if the
5146 IP/DNS could not be resolved. Though, it returns the IP address
5147 now even if it could not resolve it (but returns also FALSE).
5148 Affected file lib/silcutil/silcnet.[ch].
5150 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Added silc_pkcs_decode_identifier to decode the public key's
5153 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5154 Added also silc_pkcs_free_identifier. Added also new context
5155 SilcPublicKeyIdentifier.
5157 * Added -S option to the silc client. It is used to dump the
5158 contents of the specified public key file.
5160 * Changed the PKCS api to return the public key length when
5161 setting the public key.
5163 * Fixed a fatal bug in the public and private key file loading.
5164 Affected file lib/silccrypt/silcpkcs.c.
5166 * Execute the packet parsing for client with zero (0) timeout
5167 if the protocol is active. Affected file silcd/server.c.
5169 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5171 * Made the key generation options to the silcd program. Added
5172 -C option, equivalent to client's option.
5174 * Added new [ServerKeys] config section to the server. It
5175 configures the server's public and private key.
5177 * Defined generic Public Key Payload into the protocol
5178 specification to send specific type of public keys and
5181 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5182 public key or certificate.
5184 * Implemented the GETKEY command to the server and to the
5185 client library and on user interface.
5187 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Made preliminary `make install' work.
5191 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5193 * Added SilcServerRekey context into silcd/idlist.h.
5195 * Added the PFS support as defined in the specification to the
5196 SKE protocol. Affected files lib/silcske/*.c.
5198 * Added `ske_group' field to the SilcServerRekey context to hold
5199 the number of the SKE group that is used with PFS in re-key.
5200 Affected file silcd/idlist.h.
5202 * Added PFS re-key support to the server. Affected file is
5205 * Added silc_protocol_cancel to cancel execution of the next
5206 state of the protocol. Affected file is
5207 lib/silccore/silcprotocol.[ch].
5209 * Added the re-key support with and without PFS to the client
5210 library. Re-key is performed once in an hour, by default.
5212 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5213 Added silc_client_rekey_callback and silc_client_rekey_final.
5214 Affected files are lib/silcclient/protocol.[ch] and
5215 lib/silcclient/client.[ch].
5217 * Removed the `hmac_key' and `hmac_key_len' fields from the
5218 SilcClientConnection structure; not needed. Affected file is
5219 lib/silcclient/client.h.
5223 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Do not ask whether user wants to use the negotiated private key
5226 for private messages, just use it. Affected file is
5227 silc/local_command.c.
5229 * Added `send_enc_key' and `enc_key_len' fields to the
5230 SilcIDListData structure since they are needed in the re-key
5231 phase. Affected file is silcd/idlist.[ch].
5233 * Implemented the simple re-key protocol into the server.
5234 Affected files silcd/server.c and silcd/protocol.[ch]. The
5235 re-key will be performed once in an hour, by default.
5237 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5238 Added silc_server_rekey, silc_server_rekey_callback and
5239 silc_server_rekey_final.
5241 * Removed Tunneled flag from the protocol. Updated the code
5242 and the specifications.
5244 * Adde `pfs' field to the SilcIDListData to indicate whether
5245 the PFS is to be performed in the re-key. Affected file is
5248 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5251 int64 of at least the xintXX size. If void * is less that 4
5252 bytes uint32 * will be used. Defined bool as boolean.
5254 * Changed _ALL_ unsigned long and unsigned int to uint32,
5255 unsgined short to uint16 in the source tree.
5257 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5258 not handle clients that has entry->data.registered == FALSE.
5259 They are not in the network anymore. Affected file is
5262 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Implemented the sending of the SERVER_SIGNOFF notify in the
5265 server. Affected file is silcd/server.c.
5267 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5268 Added also silc_notify_payload_encode_args into the
5269 lib/silccore/silcnotify.[ch].
5271 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5272 Affected file silcd/packet_receive.c.
5274 * Implemented the SERVER_SIGNOFF notify handling in the client
5275 library. Affected file lib/silcclient/client_notify.c. Also,
5276 implemnted the printing of the SERVER_SIGNOFF info to the
5277 application. Affected file silc/client_ops.c.
5279 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5280 if the deleting was successful. Affected file silcd/idlist.[ch].
5282 * Added support for public key authentication in the connection
5283 authentication protocol in the client library. Affected file
5284 lib/silcclient/protocol.c.
5286 * Changed the server's silc_idlist_get_clients_by_* interface
5287 to support already allocated array so that new entries may be
5288 added to pre-allocated array. Affected file silcd/idlist.[ch].
5289 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5290 and command replies.
5292 * All command reply functions in the server now calls the
5293 pending command callback even if error occured. This way the
5294 error will be delivered to the client as well. Affected files
5295 silcd/command.c and silcd/command_reply.c.
5297 * Fixed INFO command to return local server's info if no server
5298 was provided. Affected file lib/silcclient/command.c.
5300 * Removed RESTART command for good. Updated the code and the
5303 * Rewrote parts of the task system. It is a bit simpler now.
5304 Removed unsued task priorities. The affected files are
5305 lib/silcutil/silctask.[ch].
5307 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Moved the USERS printing from the library to the application.
5310 Affected files lib/silcclient/command.c and silc/client_ops.c.
5312 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added channel key re-key support. The re-key is perfomed
5317 only by the router and is done once in an hour. Added `rekey'
5318 field to the SilcChannelEntry in the server. Affected files
5319 silcd/server.c and silcd/idlist.h.
5321 * Added silc_task_unregister_by_context into the file
5322 lib/silcutil/silctask.[ch].
5324 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5326 * Added SILC_UMODE_GONE mode to indicate when the client is not
5327 present in the SILC network. Added also support to the local
5328 command AWAY that will set this mode. Added support of showing
5329 "xxx is gone" in WHOIS command. The USERS command shows the
5330 gone status as well.
5332 * Fixed setting server and router operator privileges in the
5333 server's UMODE command. Affected file silcd/command.c.
5335 * Merged the SKE KE1 and KE2 payloads into one payload. The
5336 new KE payload is equivalent to the old KE2 payload.
5338 Cleaned up the SKE Start Payload parsing. It now uses the
5339 simple buffer unformatting to do the parsing. A lot faster
5342 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5343 to the SKE that is used to indicate whether both of the SKE
5344 parties should perform authentication. By default only the
5345 responder performs authentication. By setting this flag also
5346 the initiator must do authentication. By default it is unset
5347 since in normal SKE case, client to server connection, only
5348 the responder should do authentication. When doing SKE between
5349 two clients both should perform authentication. Updated the
5350 code and the protocol specs.
5352 * A little fix to IDENTIFY command in the server. Search the
5353 client first by hash not nickname. Affected file is
5356 * Fixed the silc_client_close_connection to support closing
5357 the client to client connections wihtout deleting too much
5358 data. Affected file lib/silcclient/client.c.
5360 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5361 are received if protocol used to be active but is not anymore
5362 the application would crash due to NULL pointer dereference.
5363 Affected files silcd/server.c and lib/silcclient/client.c.
5365 * Added `hash' field to the SilcClientConnection to include
5366 the hash function negotiated in the SKE protocol.
5368 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5369 to set the channel founder authentication data. A client can
5370 claim the founder rights later by providing the authentication
5371 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5372 This way the channel founder can regain the channel founder
5373 privileges even it is left the channel. This works only on
5374 local server and the client must be connected to the same
5375 server to be able to regain the founder rights. Updated the
5376 protocol specs accordingly.
5378 Added support to the CMODE command in the client to set the
5379 founder auth data. Read the README to see how to set it.
5381 Added support to the CUMODE command to claim the founder
5382 rights. Read the README to see how to do it.
5384 Added support for the founder authentication to the Channel
5385 Entry in the server. Affected file silcd/idlist.h.
5387 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5388 server's CMODE command. Affected file silcd/command.c.
5390 * Added the following new functions into lib/silccore/silcauth.[ch]:
5391 silc_auth_get_method and silc_auth_get_data.
5393 * The server now saves the remote hosts public key to the
5394 SilcIDListData pointer. Affected file silcd/protocol.c.
5396 * The normal server now does not remove the channel entry from
5397 the cache if the founder authentication data is set. It used
5398 to remove it if the founder was the last one on the channel on
5399 the server and left the channel. The auth data is saved and
5400 if the channel is re-joined later the old entry is used with
5401 the old auth data. Affected files silcd/command_reply.c and
5404 * Removed the `pkcs' field from the SilcIDListData structure
5405 in the server; it is not used. Affected file silcd/idlist.h.
5407 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Fixed packet processing on slow links. Partial packets were
5410 never re-processed because the incoming data buffer was cleared
5411 by the application. Application must not directly clear the
5412 sock->inbuf, the packet processing routines handle it. Fixed
5413 this in client library and in server.
5415 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5417 * Fixed the WHOIS and IDENTIFY send reply function to really
5418 check whether to send list or just one entry. Affected file
5421 * Cleaned up the LEAVE command's channel key distribution. The
5422 affected file silcd/command.c.
5424 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5425 can enforce the channel mode as well. In that case the ID
5426 includes the ID of the server. The code now enforces the
5427 mode change if the router have different mode than the server.
5429 * The notify client operation with CMODE_CHANGE notify can now
5430 return NULL client_entry pointer if the CMODE was not changed
5431 by client. Application must check for this.
5433 * Added <Server ID> argument to INFO command to support server
5434 info fetching by Server ID.
5436 * Added silc_server_announce_get_channel_users to get assembled
5437 packets of channel users of the specified channel. Affected
5438 file silcd/server.[ch].
5440 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5441 was freed underneath the ID Cache.
5443 * Re-announce clients when the server received CHANNEL_CHANGE
5444 notify from the router. Affected file silcd/packet_send.c.
5446 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5449 crashed since it did not handle the fact that there is no cipher
5450 called "3" and didn't check the error condition. Now fixed.
5452 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5453 flag. It can be used to send message requests.
5455 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Implemented the RESTART command in the client.
5459 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5460 notice type messages. Added notice printing to the user
5463 * The channel keys are not re-generated if the channel's mode
5464 is PRIVKEY, ie private key on the channel exists. Affected
5465 files silcd/server.c and silcd/command.c.
5467 * Fixed a little bug in channel message delivery when channel
5468 private keys are set in the server. Affected file is
5469 silcd/packet_send.c.
5471 * Changed the setting on channel->on_channel = TRUE from the
5472 silc_client_save_channel_key to the JOIN command reply. The
5473 key payload is not received if the private channel key is set.
5474 Affected file lib/silcclient/command_reply.c and the
5475 lib/silcclient/client_channel.c.
5477 * When the CMODE_CHANGE notify is sent and the channel private
5478 key mode is removed the channel key must be re-generated in
5479 other cells as well. Added this support for the router in the
5480 silcd/packet_receive.c.
5482 * Added new local command NOTICE to send notice message on
5483 channel. Affected file silc/local_command.[ch].
5485 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Added new local command ME to the client. It is used to send
5488 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5489 some action. Affected file silc/local_command.[ch].
5491 * Changed channel_message and private_message client operations
5492 to deliver the message flags to the application. Added also
5493 the `flags' arguments to the silc_client_send_channel_message
5494 and silc_client_send_private_message functions. Affected file
5497 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5499 * Redefined the Private Message Payload to support private message
5500 keys and to support the new private message flags. Updated
5501 the protocol specs. Flags makes it possible to have for example
5502 CTCP style messages.
5504 * Added new type SilcPrivateMessagePayload and defined an API
5505 for it in the lib/silcclient/silcprivate.[ch].
5507 * Tested private message private keys successfully. Tested the
5508 private message key set, unset and list commands with the new
5511 * Redefined the Channel Message Payload to include the channel
5512 message flags (equal with private message flags) to support
5513 for example CTCP style messages.
5515 * Defined some of the message (for channel and private message)
5516 flags. Updated the protocol specs and added the flags to the
5517 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5519 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Added SilcKeyAgreementStatus type to the key agreement routines
5522 to indicate the current status and error if one occured.
5523 The status types are defined in the lib/silcclient/silcapi.h.
5525 * Added new local command KEY that is used to set and unset private
5526 keys for channels, set and unset private keys for private messages
5527 with remote clients and to send key agreement requests and
5528 negotiate the key agreement protocol with remote client. The
5529 key agreement is supported only to negotiate private message keys,
5530 it currently cannot be used to negotiate private keys for channels,
5531 as it is not convenient for that purpose.
5533 * Fixed a minor pending callback setting bug in the function
5534 silc_client_get_client_by_id_resolve, now the function works.
5535 Affected file lib/silcclient/idlist.c.
5537 * Added function silc_net_get_local_port to get local bound
5538 port by socket. Added to lib/silcutil/silcnet.[ch].
5540 * Added `sockets' and `sockets_count' fields to the SilcClient
5541 object. They hold the sockets of the listenning sockets in
5542 the client. Listenning sockets may be for example the key
5543 agreement server. Affected file lib/silcclient/client.[ch].
5544 Added functions the silc_client_add_socket and the
5545 silc_client_del_socket. They are exported to the application
5548 * Added ~./silc/clientkeys to support other client's public keys.
5550 * Renamed verify_server_key client operation to verify_public_key
5551 and added one argument to indicate the type of the connection
5552 (server, client etc.).
5554 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Added silc_server_connection_auth_request to handle the
5557 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5558 silcd/packet_receive.[ch].
5560 * Added silc_server_send_connection_auth_request into the
5561 silcd/packet_send.c to send the connection auth request packet.
5563 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5566 * Fixed the public key authentication in responder side in the
5567 server. The `auth_data' pointer includes the SilcPublicKey
5568 not the path to the public key. Affected file silcd/protocol.c.
5570 * Implemented the public key authentication in the initiator side
5571 in the server. Affected file silcd/protocol.c.
5573 * Removed the [RedirectClient] config section from the server
5574 configuration. Is not needed and I don't want to implement it.
5576 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Cleaned up the CMODE command in the server. It now works
5579 correctly and supports all the modes defined in the protocol.
5580 Affected file is silcd/command.c.
5582 * Added `hmac_name' field to the SilcChannelEntry in the server
5583 to hold the default HMAC of the channel. It can be set when
5584 creating the channel (with JOIN command). Affected files
5587 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5588 type to indicate the change of the current cipher and hmac
5589 on the channel. Client can safely ignore the <cipher> argument
5590 (if it chooses to do so) since the CHANNEL_KEY packet will
5591 force the channel key change anyway. The <hmac> argument is
5592 important since the client is responsible of setting the new
5593 HMAC and the hmac key into use.
5595 * Fixed the CMODE command in the client library as well.
5597 * Tested CMODE command in router environment successfully.
5599 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Show the version of the remote client (or server) when connecting
5602 to the server. It is logged to the log file. Affected file
5603 is silcd/protocol.c.
5605 * Fixed the KILLED notify handling in the client library. The
5606 client must be removed from all channels when receiving the
5609 Also, do not remove the client entry when giving the KILL
5610 command but when the KILLED notify is received.
5612 * Removed silc_idlist_find_client_by_nickname from the server.
5613 Not needed anymore. Affected files silcd/idlist.[ch].
5615 * Implemented the CHANNEL_CHANGE notify type handling to the
5616 server. Affected file silcd/server.c.
5620 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Added silc_server_send_notify_invite to send the INVITE
5623 notify between routers.
5625 * Implemented the INVITE command correctly to the server.
5627 * Implemented the INVITE notify type handling in the server.
5629 * Implemented the INVITE command to the client library and on the
5632 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Added function silc_server_get_client_resolve to find the
5635 client entry by ID from all ID lists and then resolve it
5636 (using WHOIS) if it cannot be found. Affected file is
5639 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5641 * Implemented the BAN command to the client library.
5643 * The JOIN command in the server now checks the invite list
5646 * Changed the silc_command_reply_payload_encode_va and the
5647 silc_command_payload_encode_va to support that if argument is
5648 NULL it ignores and checks the next argument. Affected file
5649 lib/silccore/silccommand.c.
5651 * Added silc_server_send_notify_ban to send the BAN notify
5652 type between routers.
5654 * Chaned the silc_notify_payload_encode to support that if
5655 argument is NULL it ignores and checks the next argument.
5656 Affected file lib/silccore/silcnotify.c.
5658 * Tested ban lists in router environment successfully.
5660 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Implemented BAN command to the server, in silcd/command.[ch].
5664 * Removed the BAN and INVITE_LIST modes from the CMODE command
5667 * Added function silc_string_match to regex match two strings.
5668 Affected files lib/silcutil/silcutil.[ch].
5670 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5672 * Redefined parts of the SilcChannelEntry in the server to support
5673 the new ban and invite lists.
5675 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5677 * Redefined the INVITE command. The same command can be used to
5678 invite individuals to the channel but also to manage the invite
5679 list of the channel (to add to and remove from the invite list).
5680 Updated the protocol specs.
5682 * Added new command SILC_COMMAND_BAN that can be used to manage
5683 the ban list of the channel. Updated the protocol specs.
5685 * Removed the channel modes: the SILC_CMODE_BAN and the
5686 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5687 in the CMODE command. The equivalent features are now available
5688 using INVITE and BAN commands. Updated the protocol specs.
5690 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5691 in the network about change in the current ban list. The notify
5692 type is not used by the client.
5694 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5695 support the invite lists.
5697 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5699 * Added new function silc_string_regexify that converts string
5700 including wildcard characters into regex string that can
5701 be used by the GNU regex library. Added into the file
5702 lib/silcutil/silcutil.[ch].
5704 Added silc_string_regex_combine to combine to regex strings
5705 into one so that they can be used as one regex string by
5706 the GNU regex library. Added into the file
5707 lib/silcutil/silcutil.[ch].
5709 Added silc_string_regex_match to match two strings. It returns
5710 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5712 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Imported GNU regex to the soruce tree into lib/contrib.
5715 Fixed some compiler warning from the regex.c.
5717 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Fixed MOTD command in the server to work in router environment.
5721 * Fixed the MOTD command in the client library to support
5722 the server argument in the command.
5724 * Added `nickname_len' argument to the silc_idlist_add_client
5725 in the server, as the `nickname' argument may be binary data
5728 * Added silc_idlist_get_channels to return all channels from
5731 * Implemented LIST command to the server. Affected file is
5734 * Implemented the LIST command to the client library and on the
5737 * Added [<user count>] argument to the LIST command reply.
5738 With private channels the user count is not shown.
5740 * Updated TODO and README.
5742 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * The client entry's data.registered must be TRUE even with
5745 global client entry on global client list. The data.registered
5746 is used to check whether the client is anymore in the network,
5747 for example with WHOWAS command so it must be valid.
5749 * Fixed the WHOWAS command in the server. It now actually works
5750 in router environment. Added function into silcd/command_reply.c
5751 silc_server_command_reply_whowas_save.
5753 * Added silc_idlist_purge function to the silcd/idlist.c
5754 to periodically purge the ID Cache.
5756 * Fixed INFO command in the server. It works now in router
5757 environment. Added <server name> argument to the INFO command
5758 reply. Updated the protocol specs.
5760 * Fixed minor bug in silc_idcache_purge to not purge if the
5761 expire value is zero.
5763 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5764 they were buggy because of the WHOWAS information.
5766 * Fixed local command MSG to handle the async resolving of
5767 the remote client properly. It used to fail the first MSG.
5768 Affected file silc/local_command.c.
5770 * Added `data_len' field to SilcIDCache context.
5772 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Update TODO. Todo in commands in the server.
5776 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5779 used by routers as broadcast packet to inform other routers
5780 about the changed user mode.
5782 Implemented the notify handling in the server. Affected file is
5783 silcd/packet_receive.c. Added the function
5784 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5786 * Added new generic Channel Payload and deprecated the New Channel
5787 Payload. The New Channel Payload is now the generic Channel
5790 * Added new argument `mode' to the silc_server_send_new_channel
5791 as it is required in the Channel Payload now.
5793 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5794 and created a new and real SilChannelPayload to represent the
5795 new generic Channel Payload. Implemented the encode/decode
5796 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5798 * Added silc_server_get_client_channel_list to return the list
5799 of channels the client has joined for WHOIS command reply.
5800 Affected file silcd/server.[ch].
5802 * Implemented the channel list sending in the WHOIS command reply
5803 in server and in the client.
5805 Implemented the channel list displaying on the user interface
5806 as well. Affected file silc/client_ops.c.
5808 * Added silc_channel_payload_parse_list to parse list of Channel
5809 Payloads. It returns SilcDList list of SilcChannelPayloads.
5810 Client for example can use this function to parse the list of
5811 channels it receives in the WHOIS command reply. The caller
5812 must free the list by calling silc_channel_payload_list_free.
5813 Affected files lib/silccore/silcchannel.[ch].
5815 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Added one new argument <user mode> to the WHOIS command reply
5818 to return the mode of the user in SILC. Updated the protocol
5821 Implemented it to the server and client.
5823 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5825 * Fixed the mode printing on the user interface on joining.
5826 Affected file silc/client_ops.c.
5828 * Implemented the UMODE command and user modes in general to the
5829 client library and to the user interface.
5831 * Implemented the UMODE command to the server.
5833 * The server now sends UNKNOWN_COMMAND error status if client sends
5834 unknown command. Affected file silcd/command.c.
5836 * All server commands now handle the command identifier the right
5837 way when sending the command reply to the client. The client can
5838 use to identify the command replies with the identifier.
5840 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added silc_server_get_client_route to resolve the route to
5843 the client indicated by the client ID. Affected file is
5846 * Added silc_server_relay_packet as general function to relay
5847 packet to arbitrary destination. This deprecates functions
5848 like _send_private_message_key, _relay_notify etc. Affected
5849 file is silcd/packet_send.[ch].
5851 Removed silc_server_send_key_agreement,
5852 silc_server_send_private_message_key and
5853 silc_server_packet_relay_notify functions from the file
5854 silcd/packet_send.[ch].
5858 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5859 server. Affected file silcd/packet_receive.[ch].
5861 * Implemented the KILL command to the client. Implemented the
5862 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5863 Affected files lib/silcclient/command[_reply].c and
5864 lib/silcclient/client_notify.c. Implemented the KILL notify
5865 printing in the user inteface.
5867 * Fixed a lot silc_parse_nick memory leaks from the client
5868 library in the file lib/silcclient/command.c.
5870 * Changed the silc_server_send_notify_on_channels's `sender'
5871 argument from SilcSocketConnection to SilcClientEntry to
5872 check the sender as entry and not as connection object and not
5873 to send to the client provided as argument. The affected file
5874 is silcd/packet_send.[ch].
5876 * The notify packets that are destined directly to the client used
5877 to not to be processed by the server. Now changed that and the
5878 server processes all notify packets. After relaying the packet
5879 to the client the notify packet is processed in the server.
5881 * The silc_server_free_client_data now checks whether there is
5882 pending outgoing traffic for the client and purges the data to
5883 the network before removing the client entry.
5885 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5888 an client is killed from the SILC Network. Updated the protocol
5891 Added new function silc_server_send_notify_killed to the
5892 silcd/packet_send.[ch].
5894 * Added function silc_server_packet_relay_notify to relay notify
5895 packets that are destined directly to a client. In this case
5896 the server does not process the notify packets but merely relays
5897 it to the client. Affected file silcd/packet_send.[ch].
5899 Added also silc_server_packet_process_relay_notify to check
5900 whereto relay the notify. Affected file is
5901 silcd/packet_receive.[ch].
5903 * Implemented the KILL command to the server.
5907 * Added the backup schema desgined last fall to the protocol
5908 specs for everyone to see. The specification is in the
5909 *-spec-xx.txt draft and the packet type definitions for the
5910 backup routers is in *-pp-xx.txt draft. Thusly, added also
5911 new packet type SILC_PACKET_CELL_ROUTERS.
5913 * A big security problem in the implementation discovered. The
5914 signoff of an client did not cause new channel key generation
5915 which it of course should've done. The channel keys must be
5916 always re-generated when client leaves (or signoffs) the channel.
5917 The silc_server_remove_from_channels funtion now handles
5918 the channel key re-generation.
5920 * Added `sender' argument to the silc_server_send_notify_on_channels
5921 to not to send the client provided as argument. Affected file
5922 silcd/packet_send.[ch].
5924 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Implemented OPER and SILCOPER commands into the server and
5929 * Added silc_auth_verify and silc_auth_verify_data to verify
5930 the authentication directly from the authentication payload.
5931 It supports verifying both passphrase and public key based
5932 authentication. Affected file lib/silccore/silcauth.[ch].
5934 * Added `hash' field to the SilcIDListData structure. It is the
5935 hash negotiated in the SKE protocol. Affected file is
5938 * Slight redesigning of the SilcAuthPayload handling routines.
5939 Do not send SilcPKCS but SilcPublicKey as argument.
5941 * Implemented the public key authentication support to the
5942 serverconfig. The public key is loaded from the provided path
5943 and saved as authentication data to void * pointer. Thus,
5944 changed the unsigned char *auth_data to void *auth_data;
5946 * Fixed SHUTDOWN command to send the reply before the server
5947 is shutdown. :) Affected file silcd/command.c.
5949 * Fixed fatal bug in CONNECT command. The hostname was invalid
5950 memory and server crashed. Affected file silcd/command.c.
5952 * Fixed fatal bug in CLOSE command. The server_entry became
5953 invalid but was referenced later in the command. Affected file
5956 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5958 * Fixed fatal bug in failure packet handling. Server ignored
5959 the failure and thus crashed when it came.
5963 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5966 that the command may be executed only once in (about) 2 seconds.
5967 The old SILC_CF_LAG flag is same but allows command bursts up
5968 to five before limiting.
5970 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5971 server code. Various commands now includes the CF_LAG_STRICT
5972 flag to disallow any kind of miss-use of the command.
5974 * Fixed the silc_buffer_unformat to not to allocate any data
5975 if the length of the data is zero. It used to allocate the
5976 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5978 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Changed the format of AdminConnection configuration section
5981 in the server. Added username of the admin to the format.
5982 Affected files silcd/serverconfig.[ch].
5984 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5985 to return admin configuration data by host, username and/or
5988 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Implemented WHOWAS command to the server. Added the functions:
5992 silc_server_command_whowas_parse,
5993 silc_server_command_whowas_send_reply,
5994 silc_server_command_whowas_from_client and
5995 silc_server_command_whowas_from_server
5997 * Added <Client ID> argument to the WHOWAS command reply. Updated
5998 the protocol specs accordingly.
6000 * Implemented WHOWAS command and command_reply to the client
6003 Implemented the WHOWAS printing on the user interface.
6005 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Added new argument to the WHOWAS command reply, the real name.
6008 It is an optional argument. Updated the protocol specs.
6010 * Added SilcIDCacheDestructor callback that is registered when
6011 the SilcIDCache is allocated. The callback is called when
6012 an cache entry in the ID Cache expires, or is purged from the
6013 cache. Added into lib/silccore/idcache.[ch].
6015 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6016 to destruct the client entries when the cache entry expires.
6017 Other ID Cache's in server and in the client library ignores
6020 * If the ID Cache entry's `expire' field is zero then the entry
6021 never expires. Added boolean `expire' argument to the
6022 silc_idcache_add function in the lib/silccore/idcache.[ch].
6023 If it is TRUE the default expiry value is used.
6025 * Added silc_server_free_client_data_timeout that is registered
6026 when client disconnects. By default for 5 minutes we preserve
6027 the client entry for history - for WHOWAS command.
6029 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Added support to the server to enforce that commands are not
6032 executed more than once in 2 seconds. If server receives
6033 commands from client more frequently, timeout is registered
6034 to process the commands. Affected file silcd/command.c.
6035 Added new function silc_server_command_process_timeout.
6037 * Changed NICK_NOTIFY handling in client library to check that
6038 if the client's nickname was changed, so there is no need to
6039 resolve anything from the server.
6041 * Removed error printing from the WHOIS and IDENTIFY commands.
6042 If error occurs then it is ignored silently in the client library.
6043 The application, however, may map the received error to
6044 human readable error string. The application currently maps
6045 the NO_SUCH_NICKNAME error to string.
6047 * Made the command status message public to the application. Moved
6048 them from lib/silcclient/command_reply.c to
6049 lib/silcclient/command_reply.h. The application can map the
6050 received command status to the string with the
6051 silc_client_command_status_message function.
6053 * Added check to the server to check that client's ID is same
6054 as the Source ID in the packet the client sent. They must
6057 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Added dist-bzip hook to the Makefile.am to make bzip2
6060 compressed distributions.
6062 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6064 * Server now enforces the maximum length for the nickname and
6065 the channel as protocol specification dictates. 128 bytes for
6066 nickname and 256 bytes for channel name.
6068 * Moved the WHOIS printing to the application. The client libary
6069 does not print out the WHOIS information anymore, the application
6070 must do it. Renamed silc_client_command_reply_whois_print to
6071 the silc_client_command_reply_whois_save.
6073 The client's idle time is also sent to the application now, and
6074 the idle is shown on screen.
6076 * Added silc_client_command_reply_identify_save to save the
6077 received IDENTIFY entries.
6079 * Do not check for channel private keys in message sending and
6080 reception if the channel does not have the PRIVKEY mode set.
6081 Affected file lib/silclient/client_channel.c.
6083 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6086 just surfaced after chaning the JOIN procedure.
6088 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Added silc_client_get_clients_by_list to get client entries
6091 from Client ID list, that is returned for example by JOIN
6092 and USERS command replies. The application should use this
6093 function for example when JOIN command reply is received to
6094 resolve the clients already on the channel (library does not
6095 do that anymore as USERS command reply is not used in the JOIN
6096 procedure anymore). Affected files lib/silcclient/silcapi.h and
6097 lib/silcclient/idlist.c.
6099 * JOIN command reply and USERS command reply returns now SilcBuffer
6100 pointers instead of unsigned char pointers when returning
6101 the client list and mode list.
6103 * Added <Client ID> argument to the JOIN command reply, mainly
6104 for the server to identify for which client the command was
6105 originally sent. Updated protocol specs accordingly.
6107 * Added SilcDlist private_key pointer to the SilcChannelEntry
6108 in the client to support the channel private keys. Affected
6109 file is lib/silcclient/idlist.h.
6111 * Added SilcChannelPrivateKey argument to the function
6112 silc_client_send_channel_message so that application can choose
6113 to use specific private ke if it wants to. If it is not provided,
6114 the normal channel key is used, unless private keys are set.
6115 In this case the first (key that was added first) is used
6116 as the encryption key.
6118 * Implemented the support for channel private key handling.
6119 Implemented the following functions:
6121 silc_client_add_channel_private_key,
6122 silc_client_del_channel_private_keys,
6123 silc_client_del_channel_private_key,
6124 silc_client_list_channel_private_keys and
6125 silc_client_free_channel_private_keys
6127 Affected file lib/silcclient/client_channel.c.
6129 * Added the support for the private keys in the channel message
6130 sending and encryption and in the message reception and
6131 decryption. Affected funtions are
6132 silc_client_send_channel_message and silc_client_channel_message.
6134 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6136 * Added SKE's key verify callback to the client library's
6137 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6139 * Removed the statement that server (or router) must send USERS
6140 command reply when joining to the channel so that the client
6141 knows who are on the channel. Instead, the client list and
6142 client's mode list is now sent in the JOIN command reply to the
6143 client who joined channel. This is better solution.
6145 * Added function silc_server_get_users_on_channel and function
6146 silc_server_save_users_on_channel to the silcd/server.[ch].
6148 * Removed function silc_server_command_send_users from the
6151 * Do not show topic on the client library anymore. The topic is
6152 sent in the command reply notify to the application and the
6153 application must show the topic now.
6155 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Added client searching by nickname hash into the IDENTIFY and
6158 WHOIS commands in the server as they were clearly missing from
6159 them. Affected file is silcd/command.c.
6161 * Fixed a bug in private message receiving in the client library.
6162 The remote ID was freed and it wasn't supposed, now it is
6165 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Minor fix to the channel payload; allocate the data area, as it
6168 needs to be of specific length.
6170 * If the key agreement port is zero then the operating
6171 system will define the bound port. Affected files are
6172 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6174 * Added new function silc_channel_payload_decrypt into the file
6175 lib/silccore/silcchannel.[ch].
6177 * Moved the channel message etc, check from silc_packet_decrypt
6178 to applications. The library calls now a generic
6179 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6180 when the packet is either normal or special. This was done to
6181 allow more wide range of checking that was not allowed when
6182 the code was in library. Now applications can do virtually any
6183 checks to the packet and return to the library the decision how
6184 the packet should be processed. Affected files are
6185 lib/silccore/silcpacket.[ch].
6187 Added silc_server_packet_decrypt_check to the server and
6188 silc_client_packet_decrypt_check to the client library.
6190 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6191 to send with specified source and destination information.
6193 * Channel message delivery between routers was broken after the
6194 channel key distribution was fixed earlier. The channel key
6195 was used be to distributed to other routers as well which is not
6196 allowed by the protocol. Now this is fixed and channel keys
6197 really are cell specific and the channel message delivery between
6198 routers comply with the protocol specification.
6200 * Fixed various commands in server to check also the global list
6201 for the channel entry and not just the local list. The affected
6202 file silcd/command.c.
6204 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Added assert()s to buffer formatting and unformatting routines
6207 to assert (if --enable-debug) when error occurs. Affected
6208 file: lib/silcutil/silcbuffmt.c.
6210 * Changed to auto-reconnect to check whether the remote host is
6211 router and register the re-connect timeout if it is. It used
6212 to check that whether we are normal server, but router must do
6213 auto-reconnect with another router as well. Affected file
6216 * Removed the [<key len>] option from CMODE command as the cipher
6217 name decides the key length, nowadays. See the defined ciphers
6218 from the protocol specification.
6220 * Added [<hmac>] option to the CMODE command to define the HMAC
6221 for the channel. Added SILC_CMODE_HMAC channel mode.
6223 * Added [<hmac>] option for the JOIN command so that user can
6224 select which HMAC is used to compute the MACs of the channel
6227 * Added Hmac field to the Channel Message Payload. The integrity
6228 of plaintext channel messages are now protected by computing
6229 MAC of the message and attaching the MAC to the payload. The
6230 MAC is encrypted. Now, it is clear that this causes some
6231 overhead to the size of the packet but rationale for this is that
6232 now the receiver can verify whether the channel message decrypted
6233 correctly and also when private keys are set for the channel the
6234 receiver can decrypt the packet with several keys and check from
6235 the MAC which key decrypted the message correctly.
6237 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6238 lib/silccrypt/silccipher.[ch].
6240 * Added silc_hash_len to return the digest length into the
6241 lib/silcrypt/silchash.[ch].
6243 * Rewrote parts of Silc Channel Payload interface in the
6244 lib/silccore/silcchannel.[ch]. The encode function now also
6245 encrypts the packet and parse function decrypts it.
6247 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Fixed a minor formatting bug in the SKE's key material processing.
6250 It actually might have processed the keys wrong way resulting
6253 * Redefined the mandatory HMAC algorithms and added new algorithms.
6254 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6255 and hmac-md5 truncated to 96 bits. The mandatory is now
6256 hmac-sha1-96. Rest are optional (including the one that used
6257 to be mandatory). Rationale for this is that the truncated HMAC
6258 length is sufficient from security point of view and can actually
6259 make the attack against the HMAC harder. Also, the truncated
6260 HMAC causes less overhead to the packets. See the RFC2104 for
6263 * Added new [hmac] configuration section. The SKE used to use
6264 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6265 is of course wrong. The official names that must be proposed in
6266 the SKE are the ones defined in the protocol specification
6267 (hmac-sha1-96 for example). The user can configure any hmac
6268 using any hash function configured in the [hash] section. At
6269 least, the mandatory must be configured.
6271 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6273 * Added HMAC list to the SKE proposal list. It has now both
6274 hash algorithm list and HMAC list. This makes the protocol
6275 incompatible with previous versions. The SKE now seems to work
6276 the way it is supposed to work, for the first time actually.
6278 * Defined plain Hash algorithms to the protocol specification.
6281 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6283 * Implemented support for key agreement packets into the server.
6284 Added functions silc_server_key_agreement and
6285 silc_server_send_key_agreement. Other than these functions,
6286 server has nothing to do with this packet.
6288 * Added support for private message key packets into the server.
6289 Added functions silc_server_private_message_key and
6290 silc_server_send_private_message_key.
6294 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6295 called in the protocol's final callback instead in the END
6296 protocol state. This makes a little more sense and in the same
6297 time in client we can use the same protocol routines for normal
6298 key exchange and to key agreement packet handling as well.
6300 * Added to both client's and server's KE protocol context the
6301 SilcSKEKeyMaterial pointer to save the key material. We will
6302 bring the key material to the protocol's final callback by doing
6303 this. The final callback must free the key material.
6305 * Added SKE's packet_send callback into client's KE protocol
6306 context so that the caller can choose what packet sending function
6307 is used. This way we can use different packet sending when
6308 doing normal SKE when doing key agreement packet handling (in
6309 the key agreement packet handling we do not want to encrypt
6312 * Implemented the responder side of the key agreement routines
6313 in the client. The client can now bind to specified port and
6314 accept incoming key negotiation. The key material is passed
6315 to the application after the protocol is over.
6317 * Implemented the processing of incoming Key Agreement packet
6318 in the client. Added function silc_client_key_agreement to
6321 * Implemented the intiator side of the key agreement routines
6322 in the client. The client can now initiate key agreement with
6323 another remote client. The key material is passed to the
6324 application after the protocol is over.
6326 * Created client_keyagr.c to include all the key agreement
6329 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6330 SILC_TASK_CALLBACK except that it is not static.
6332 * Created client_notify.c and moved the Notify packet handling
6333 from the client.[ch] into that file.
6335 * Created client_prvmsg.c and moved all private message and
6336 private message key routines from the client.[ch] into that file.
6338 * Create client_channel.c and moved all channel message and
6339 channel private key routines from the client.[ch] into that file.
6341 * Changed silc_client_get_client_by_id_resolve to resolve with
6342 WHOIS command instead of IDENTIFY command, in the file
6343 lib/silclient/idlist.c.
6345 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Implemented the SKE's responder side to the Client library.
6349 * When FAILURE is received to the protocol do not trust it
6350 blindly. Register a timeout to wait whether the remote closes
6351 the connection as it should do it, only after that process the
6352 actual failure. This was changed to both client and server.
6354 * Added client_internal.h to include some of the structures
6355 there instead of client.h in lib/silcclient/.
6357 * Added function silc_task_unregister_by_callback to unregister
6358 timeouts by the callback function.
6360 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Some "Incomplete WHOIS info" errors has been appearing on the
6363 log files. Took away the entry->userinfo check from WHOIS
6364 reply sending. The entry->userinfo is now " " if client did not
6365 provide one. I thought this was fixed earlier but something
6366 is wrong still. Let's see if the error still appears.
6368 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Fixed a minor bug in the login when the channel key is
6371 re-generated in the server. It used to generate the key in
6372 wrong order and thus caused problems in the channel traffic.
6374 * Fixed a minor bug in channel key distsribution after
6375 KICK command. The key was not sent to the router even though
6378 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Added silc_ske_process_key_material_data as generic routine
6381 to process any key material as the SILC protocol dictates. The
6382 function is used by the actual SKE library but can be used by
6383 applications as well. This relates to the private message keys
6384 and the channel private keys since they must be processed the
6385 same way the normal SILC session keys. The protocol dictates
6386 this. Affected files: lib/silcske/silcske.[ch].
6388 Added also silc_ske_free_key_material to free the
6389 SilcSKEKeyMaterial structure.
6391 * Defined silc_cipher_set_key function to set the key for
6392 cipher without using the object's method function. The affected
6393 files: lib/silccrypt/silccipher.[ch].
6395 * Implemented silc silc_client_add_private_message_key,
6396 silc_client_add_private_message_key_ske,
6397 silc_client_del_private_message_key,
6398 silc_client_list_private_message_keys and
6399 silc_client_free_private_message_keys functions in the
6402 Added functions silc_client_send_private_message_key to send
6403 the Private Message Key payload and silc_client_private_message_key
6404 to handle incoming Private Message Key payload.
6406 * Added Cipher field to the Private Message Key payload to set
6407 the cipher to be used. If ignored, the default cipher defined
6408 in the SILC protocol (aes-256-cbc) is used.
6410 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Removed lib/silcclient/ops.h file.
6414 Redefined parts of the SILC Client Library API. Created new
6415 file silcapi.h that deprecates the ops.h file and defines the
6416 published Client Library API. Defined also private message key
6417 API and channel private key API into the file.
6419 This is the file that the application must include from the
6420 SILC Client Library. Other files need not be included by
6421 the application anymore.
6423 * Added new key_agreement client operation callback and also
6424 defined the Key Agreement library API for the application.
6426 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6429 is used by clients to request key negotiation between another
6430 client in the SILC network. If the negotiation is started it
6431 is performed using the SKE protocol. The result of the
6432 negotiation, the secret key material, can be used for example
6433 as private message key.
6435 Implemented the Key Agreement payload into the files
6436 lib/silccore/silauth.[ch].
6438 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Redefined ciphers for the SILC protocol. Added some new ciphers
6441 and defined the key lengths for the algorithms. Changed the
6442 code accordingly. The default key length is now 256 bits.
6444 * Fixed SKE key distribution function silc_ske_process_key_material
6445 when the key length is more than 128 bits. The default key
6446 length in SILC is now 256 bits.
6448 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6449 to indicate unsupported algorithm.
6451 * Renamed rijndael.c to aes.c and all functions as well.
6453 * Fixed a long standing channel key setting bug in client library.
6454 Weird that it has never surfaced before.
6456 * Fixed bug in channel deletion. If the entire channel is removed
6457 then it must also delete the references of the channel entry
6458 from the client's channel list as the client's channel entry and
6459 the channel's client entry share same memory.
6461 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Implemented CONNECT and SHUTDOWN commands in the client.
6465 * Implemented CLOSE command to the client.
6467 * Added the function silc_idlist_find_server_by_name into the
6468 files silcd/idlist.[ch].
6470 Added the function silc_idlist_find_server_by_conn into the
6471 files silcd/idlist.[ch].
6473 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6475 * DIE command was renamed to SHUTDOWN. Updated the both code
6478 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6479 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6481 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6484 * Added function silc_server_create_connection function to create
6485 connection to remote router. My server implementation actually
6486 does not allow router to connect to normal server (it expects
6487 that normal server always initiates the connection to the router)
6488 so the CONNECT command is only good for connecting to another
6491 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6494 or some other client was kicked from the channel.
6496 Implemented the handling of the notify type to both client
6499 Implemented silc_server_send_notify_kicked to send the KICKED
6500 notify. It is used to send it to the server's primary router.
6502 * Implemented the KICK command into server and client.
6504 * Added `query' argument to the silc_idlist_get_client function
6505 to indicate whether to query the client from server or not if
6508 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6509 to indicate that the client is not channel founder.
6513 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6515 * Removed the rng context from SilcPacketContext structure and
6516 changed that the packet routine uses the Global RNG API.
6518 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6520 * Added support for quit message that client can "leave" on the
6521 channel when it quits the SILC. It is ditributed inside the
6522 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6524 Added silc_server_free_client_data that will take the
6525 signoff message as argument.
6527 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6529 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6531 * Updated parts of the protocol specification to keep it up
6534 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6537 payloads in one packet.
6539 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6540 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6541 use now the new List flag.
6543 * Also deprecated the following packet types: REPLACE_ID,
6544 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6546 * Added list support for Notify packet in server.
6548 * Added silc_server_send_notify_channel_change to send the
6549 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6550 the silc_server_send_replace_id.
6552 * Added silc_server_send_notify_nick_change to send the
6553 NICK_CHANGE notify type. Deprecates the function
6554 silc_server_send_replace_id.
6556 * Added silc_server_send_notify_join to send the JOIN notify type.
6557 Deprecates the function silc_server_send_new_channel_user.
6559 * Added silc_server_send_notify_leave to send LEAVE notify type.
6560 Deprecates the function silc_server_send_remove_channel_user.
6562 * Added silc_server_send_notify_cmode and
6563 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6564 types. Deprecates the silc_server_send_set_mode function.
6566 * Added SERVER_SIGNOFF notify type to indicate that server has
6567 quit. This means that all clients on the channel from that
6568 server will drop. This can be also used when netsplit happens.
6570 Deprecated REMOVE_ID packet type since it is not needed anymore
6573 Added silc_server_send_notify_server_signoff to send the
6574 SERVER_SIGNOFF notify type. Deprecates the function
6575 silc_server_send_remove_id.
6577 Added also silc_server_send_notify_signoff to send the
6578 SIGNOFF notify type.
6580 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6581 SILC protocol from this day on. Changed the protocol
6582 specification as well.
6584 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6585 notify type. It is used between routers to notify about
6586 topic changes on a channel.
6588 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6591 * Partly updated the protocol specification to comply with the
6592 changes now made. It is still though a bit outdated.
6594 * The JOIN notify type now takes one extra argument <Channel ID>.
6595 The packet used to be destined to the channel but now the
6596 JOIN type may be sent as list thus it is impossible to
6597 destine it to any specific channel. By adding this argument
6598 it is again possible.
6600 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Added CREDITS file. The CHANGES and CREDITS file will appear
6603 in the distribution as well.
6605 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6608 types in the server's silcd/packet_receive.c.
6610 * Implemented CMODE and CUMODE to work in router environment.
6612 * Fixed minor encoding and decoding buglet from the
6613 lib/silccore/silcmode.c.
6615 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6618 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6620 * Changed all SilcConfigServer* and silc_config_server* to
6621 SilcServerConfig* and silc_server_config*, respectively.
6624 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Associated the ID (client or server ID) to the Authentication
6627 Payload to avoid any possibility of forging. Updated the
6628 protocol specification and the code accordingly.
6630 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6632 * The RSA key length is now save to the RsaKey context in the
6633 key generation process in lib/silccrypt/rsa.c. The key length
6634 is now used to figure out the maximum size of the block allowed
6635 to be encrypted/signed.
6637 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6638 is equivalent to the silc_mp_mp2bin but does not allocate any
6641 * Changed silc_mp_mp2bin API to take length argument. If it is
6642 non-zero then the buffer is allocated that large. If zero, then
6643 the size is approximated using silc_mp_sizeinbase, which however
6646 * Created Global RNG API which is global RNG that application can
6647 initialize. After initializing, any routine anywhere in the
6648 code (including library) can use RNG without allocating a new
6649 RNG object. This was done to allow this sort of use of the
6650 RNG in code that has no chance to allocate RNG object. All
6651 applications currently allocate this and many routines in the
6652 library use this. Affected file lib/silccrypt/silcrng.[ch].
6654 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6655 it to use the Global RNG API.
6657 * Defined Authentication Payload into protocol specification that
6658 is used during SILC session to authenticate entities. It is
6659 used for example by client to authenticate itself to the server
6660 to obtain server operator privileges.
6662 Implemented this payload into the lib/silccore/silcauth.[ch].
6663 Implemented also routines for public key based authentication
6664 as the new protocol specification dictates.
6666 Moved definitions of different authentication methods from
6667 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6669 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6670 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6671 silc_pkcs_verify_with_hash functions into the file
6672 lib/silccrypt/silcpkcs.[ch].
6674 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * The client entry's userinfo pointer must be always valid.
6677 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6678 will fail since it requires the userinfo. Now, the userinfo
6679 is allocated as "" if actual userinfo does not exist. Actually,
6680 it must exist and it is totally Ok to drop client connections
6681 that does not announce the userinfo. However, we will make
6682 this workaround for now.
6684 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6685 to return the remote port by socket.
6687 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6690 SILC_SERVER_PENDING_EXEC and added an new macro
6691 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6692 data or when error occurs while processing the pending command.
6694 Added new argument `destructor' into silc_server_command_pending
6695 and to the SilcServerCommandPending object. This destructor is
6696 now called after calling the pending callback or if error occurs
6697 immediately. If error occurs the actual pending callback won't
6698 be called at all - only the destructor. The destructor may be
6699 NULL if destructor is not needed.
6701 All this applies for client library code as well. Similar
6702 changes were made there as well for the pending commands.
6704 In the client, the application must now allocate the
6705 SilcClientCommandContext with the silc_client_command_alloc
6708 * Added reference counter to the SilcServerCommandContext. Added
6709 function silc_server_command_alloc and silc_server_command_dup
6712 Same type of functions added to the client library for the same
6715 * Removed the cmd_ident from IDListData away since it is now
6716 global for all connections. It is the command identifier used
6717 in command sending and with pending commands. The affected file
6720 * Added reference counter to the SilcSocketConnection objecet to
6721 indicate the usage count of the object. The object won't be
6722 freed untill the reference counter hits zero. Currently only
6723 server uses this, and client ignores it. The client must be
6724 set to use this too later. The affected files are
6725 lib/silccore/silcsockconn.[ch]. Added also the function
6726 silc_socket_dup to increase the reference counter.
6728 This was mainly added because it is possible that the socket
6729 is removed underneath of pending command or other async
6730 operation. Now it won't be free'd and proper DISCONNECTING
6731 flags, etc. can be set to avoid sending data to connection that
6732 is not valid anymore.
6734 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6735 the connection. After that it sets SILC_SET_DISCONNECTED.
6736 It is, however, possible that the socket data is not still freed.
6737 The silc_server_packet_process now checks that data is not
6738 read or written to connection that is DISCONNECTED. The socket
6739 get's freed when the reference counter hits zero.
6741 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Changed the client operation API: channel_message operation's
6744 `sender' is now the client entry of the sender, not the nickname
6745 and the `channel' is the channel entry, not the channel name.
6747 In the private_message operation the `sender' is now also the
6748 client entry of the sender not the nickname.
6750 Affected file is lib/silcclient/ops.h and all applications
6751 using the client operations.
6753 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Moved the calling of ops->connect() from connect_to_server_final
6756 into receive_new_id functin since that is the point when the
6757 client is actually allowed to send traffic to network. The
6758 affected file is lib/silcclient/client.c.
6760 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6763 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6764 (if needs broadcasting) instead of broadcasting the packets one
6765 by one which would make a burst in the network traffic.
6767 * Added `broadcast' argument to the functions in silcd/server.[ch]
6768 silc_server_create_new_channel[_with_id] to indicate whether
6769 to send New Channel packet to primary router.
6771 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Added new function into the silcd/server.[ch] files:
6774 silc_server_create_new_channel_with_id to create new channel with
6775 already existing Channel ID.
6777 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6778 lib/silccore/silcpacket.h. This packet is used t send list of
6779 Set Mode payloads inside one packet. Server uses this to set
6780 the modes for the channels and clients on those channels, that it
6781 announced to the router when it connected to it. The protocol
6782 specification has been updated accordingly.
6784 * The silc_server_new_channel did not handle the packet coming
6785 from normal server as it normally does not send that. However,
6786 when it announces its channels it does send it. Implemented
6787 the support for that.
6789 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6790 into the file lib/silccore/id.h.
6792 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Fixed memory leaks in the functions silc_idlist_del_client,
6795 silc_idlist_del_channel and silc_idlist_del_server in the file
6796 silcd/idlist.c. All of those leaked like a sieve.
6798 * Fixed some small memory leaks in the client's function
6799 silc_client_notify_by_server.
6801 * Added functions into silcd/server.c: silc_server_announce_clients,
6802 silc_server_announce_channels and silc_server_announce_server.
6803 These functions are used by normal and router server to announce
6804 to its primary router about clients, channels and servers (when
6805 router) that we own. This is done after we've connected to the
6808 These functions effectively implements the following packet types:
6809 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6810 and SILC_PACKET_NEW_ID_LIST.
6812 * Added new functions into the silcd/packet_receive.[ch]:
6813 silc_server_new_id_list, silc_server_new_channel_list and
6814 silc_server_new_channel_user_list to handle the incoming
6815 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6817 * Added support of changing Channel ID in the function
6818 silc_server_replace_id. If the server that announces a channel
6819 to the router already exists in the router (with same name but
6820 with different Channel ID), router is responsible to send
6821 Replace ID packet to the server and force the server to change
6822 the Channel ID to the one router has.
6824 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6825 client that the Channel ID has been changed by the router. The
6826 normal server sends this to the client. Client must start using
6827 the new Channel ID as the channel's ID.
6829 Implemented handling of this new type into lib/silcclient/client.c
6830 into the function silc_client_notify_by_server.
6832 * Added new function silc_idlist_replace_channel_id into the files
6833 silcd/idlist.[ch] to replace the Channel ID.
6835 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Call silc_server_command_identify_check always when processing
6838 the IDENTIFY command in silcd/command.c
6840 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6843 send keepalive packets. The packet can be sent by clients,
6844 servers and routers.
6846 Added function silc_socket_set_heartbeat into the file
6847 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6848 If not set, the heartbeat is not performed. The actual
6849 heartbeat is implemented in the low level socket connection
6850 library. However, application is responsible of actually
6853 Added silc_server_send_heartbeat to send the actual heartbeat
6854 packet into silcd/packet_send.[ch]. Server now performs
6855 keepalive with all connections.
6857 * Added silc_task_get_first function into lib/silcutil/silctask.c
6858 to return the timeout task with shortest timeout. There was a bug
6859 in task unregistration that caused problems. TODO has been
6860 updated to include that task system must be rewritten.
6862 * The client library will now resolve the client information when
6863 receiving JOIN notify from server for client that we know but
6864 have incomplete information.
6866 * Rewrote parts of silc_server_remove_from_channels and
6867 silc_server_remove_from_one_channel as they did not remove the
6868 channel in some circumstances even though they should've.
6870 * Encryption problem encountered in server:
6872 The LEAVE command used to send the Channel Key packet to the
6873 router immediately after generating it. However, the code
6874 had earlier sent Remove Channel user packet but not immediately,
6875 ie. it was put to queue. The order of packets in the router
6876 was that Channel Key packet was first and Remove Channel User
6877 packet was second, even though they were encrypted in the
6878 reverse order. For this reason, MAC check failed. Now, this
6879 is fixed by not sending the Channel Key packet immediately but
6880 putting it to queue. However, this is more fundamental problem:
6881 packets that are in queue should actually not be encrypted
6882 because packets that are sent immediately gets encrypted
6883 actually with wrong IV (and thus MAC check fails). So, packets
6884 that are in queue should be encrypted when they are sent to
6885 the wire and not when they put to the queue.
6887 However, the problem is that the current system has not been
6888 designed to work that way. Instead, the packet is encrypted
6889 as soon as possible and left to the queue. The queue is then
6890 just purged into wire. There won't be any fixes for this
6891 any time soon. So, the current semantic for packet sending
6894 o If you send packet to remote host and do not force the send
6895 (the packet will be in queue) then all subsequent packets to the
6896 same remote host must also be put to the queue. Only after the
6897 queue has been purged is it safe again to force the packet
6900 o If you send all packets immediately then it safe to send
6901 any of subsequent packets through the queue, however, after
6902 the first packet is put to queue then any subsequent packets
6903 must also be put to the queue.
6905 Follow these rules and everything works fine.
6907 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Added new function silc_server_remove_clients_by_server to
6910 remove all client entries from ID list when the server connection
6911 is lost. In this case it is also important to invalidate all
6912 client entires as they hold the invalid server entry. This
6913 fixes fatal bug when server has lost connection and will reconnect
6916 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Made some sanity checks to silc_server_daemonise like to check
6919 whether the requested user and group actually exists.
6921 * Added sanity check to SKE's silc_ske_responder_finish to check
6922 that the public and private key actually is valid.
6924 * Invalidate the client's nickname when receiving Replace ID
6925 packet and the Client ID is being replaced. This means that the
6926 server will query the nickname if someone needs it (client)
6929 * Sort the ID Cache in client library when the ID Cache data
6930 has changed (needs sorting).
6932 * Do not allow for SILC client to create several connections to
6933 several servers. The client does not support windows right now
6934 and generating multiple connections causes weird behaviour.
6936 Irssi-silc client does support windows and can handle several
6937 connections without problems, see: www.irssi.org and SILC plugin.
6939 * Fixed some places where client was added to the IDList. The
6940 rule of thumb is following (in order to get everything right):
6941 If the client is directly connected local client then the
6942 `connection' argument must be set and `router' argument must be
6943 NULL to silc_idlist_add_client function. If the client is not
6944 directly connected client then the `router' argument must
6945 bet set and the `connection' argument must be NULL to the
6946 silc_idlist_add_client function.
6948 * The funtion silc_server_packet_send_local_channel actually did
6949 not check whether the client was locally connected or not. It
6950 does that now. Fixed a bug related to LEAVE command.
6952 * Fixed Remove Channel User payload parsing bug in server's
6953 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6955 * The server's silc_server_save_channel_key now checks also the
6956 global ID list for the channel as it might not be in the local
6957 list. Fixed a bug related to LEAVE command.
6959 * Is this the end of the [<unknown>] buglet that has been lurking
6960 around for a long time? A little for loop fix in server's
6961 silc_server_command_whois_parse that is used by both IDENTIFY
6962 and WHOIS command. At least, this was a clear bug and a cause
6963 of one type of [<unknown>] buglet.
6965 * WHOIS and IDENTIFY commands call the function
6966 silc_server_command_[whois/identify]_check function even if
6967 we are not router server.
6969 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Added --with-gmp configuration option. If set the GMP
6972 is always compiled in the SILC source tree. If not set then
6973 it is checked whether the system has the GMP3 installed. If
6974 it has then the GMP won't be compiled (the system's headers
6975 and library is used), if it doesn't have it then the GMP is
6976 compiled in the SILC source tree.
6978 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Changed RSA private exponent generation to what PKCS #1
6981 suggests. We try to find the smallest possible d by doing
6982 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6983 not security fix but optimization.
6985 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * Added new config entry [Identity] to fork the server and run
6988 it as specific user and group. A patch from Bostik.
6990 * Imported Dotconf configuration library into lib/dotconf.
6991 This will be used to create the SILC configuration files later.
6992 It will appear in the distsribution after this commit.
6994 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * A big code auditing weekend happening. Auditing code for
6997 obvious mistakes, bugs and errors. Also, removing any code
7000 Removed files for being obsolete:
7002 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7003 inline in the file lib/silcutil/silcbuffer.h)
7005 o lib/silcutil/silcbufutil.c (the header has inline versions)
7007 Changed code to fix possible error conditions:
7009 o The buffer formatting routines now check that the destination
7010 buffer really has enough space to add the data. This applies for
7011 both buffer formatting and unformatting
7012 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7013 unformatting was changed to accomodate following rules:
7014 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7015 sent to the function while XXX_*STRING will not allocate or copy
7016 the data into the buffer. Instead it sets the pointer from the
7017 buffer into the pointer sent as argument (XXX_*STRING used to
7018 require that the pointer must be allocated already). This change
7019 makes this whole thing a bit more consistent and more optimized
7020 (note that the data returned in the unformatting with XXX_*STRING
7021 must not be freed now). The routines return now -1 on error.
7023 o Tried to find all code that use buffer_format and buffer_unformat
7024 and added return value checking to prevent formatting and
7025 especially unformatting errors and possible subsequent fatal
7028 o Changed ske->x and ske->KEY to mallocated pointers in
7029 lib/silcske/silcske.h. Fixed possible data and memory leak.
7031 o Added return value checking to all *_parse* functions. Fixed
7032 many memory leaks as well.
7034 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7035 so that buffer overflows would not happen. All code now also
7036 checks the return value as it can fail.
7038 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Added reconnection support to server if the normal server looses
7041 its connection to the router (for example if router is rebooted).
7042 The server performs normal reconnection strategy implemented
7043 to the server. Affected file silcd/server.c.
7045 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7047 * Added new packet type SILC_PACKET_SET_MODE that is used to
7048 distribute the information about changed modes (for clients,
7049 channels and clients channel modes) to all routers in the
7050 network. Updated the protocol specification accordingly.
7052 Added functions into silcd/packet_send.c and
7053 silcd/packet_receive.c: silc_server_send_set_mode,
7054 silc_server_set_mode.
7056 Added new files silcmode.[ch] into lib/silccore that implements
7057 the encoding and decoding of Set Mode Payload. Added new type
7058 SilcSetModePayload. Moved the definitions of different modes
7059 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7061 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Oops, a little mistake in server's connection authentication
7064 protocol. The protocol is not ended with FAILURE but with
7065 SUCCESS if the authentication is Ok. :) Affected file is
7068 * Implemented NICK_CHANGE notify handling in server in the file
7069 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7070 the local clients on the channel. After the changing nickname
7071 in router environment snhould work and the [<unknown>] nickname
7072 should appear no more.
7074 The silc_server_replace_id function that receives the Replace ID
7075 payload now sends the NICK_CHANGE notify type also in the file
7076 silcd/packet_receive.c
7078 * Changed WHOIS and IDENTIFY command to support the maximum amount
7079 of arguments defined in protocol specs (3328 arguments). This
7080 fixed a bug that caused problems when there were more than three
7083 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Added extra parameter, command identifier, to the
7086 silc_client_send_command so that explicit command identifier
7089 Changed that ID list routines uses specific command identifier
7090 when sending WHOIS/IDENTIFY requests to the server so that they
7091 can be identified when the reply comes back.
7093 Affected files lib/silcclient/command.[ch],
7094 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7096 * Added `sender' argument to silc_server_packet_send_to_channel
7097 to indicaet the sender who originally sent the packet to us
7098 that we are now re-sending. Ignored if NULL. Affected file
7099 silcd/packet_send.[ch].
7101 * Added some server statistics support in silcd/server_internal.h
7102 SilcServerStatistics structure and around the server code. Also
7103 send some nice statistics information when client is connecting
7106 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * Fixed channel ID decoding in server's JOIN command reply in
7109 silcd/command_reply.c
7111 * Fixed braodcasting of replace ID payload to not to send it if
7112 we are standalone server in silcd/packet_receive.c.
7114 * Fixed all channel message sending routines to not to send
7115 packets to clients that has router set, since they are routed
7116 separately in the same function earlier. Affects file
7117 silcd/packet_send.c and all channel packet sending functions.
7119 * In USERS reply, res_argv[i] are not allocated, the table
7120 is allocated. Thus changed that free the table, not its
7123 * In server's whois_check and identify_check if the client is
7124 locally connected do not send any WHOIS commands - they are not
7127 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Fixed some minor bugs in client when sending WHOIS command. The
7130 arguments was in wrong order.
7132 * Removed statis function add_to_channel from server in
7133 silcd/command.c that was previously used with the joining but
7136 * Tested USERS command in router environment successfully with two
7137 routers, two servers and two clients.
7139 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Reorganized the USERS command and command reply in client library
7142 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7143 When the command is given by user we register a pending command
7144 callback that will reprocess the command after the reply has been
7145 received from the server. When reprocessing the packet we then
7146 display the information. Thus, the USERS information is displayed
7147 now in the command callback instead of in the command reply
7148 callback. The processing of the command is same as previously
7149 when server has sent the command reply in the JOINing process.
7151 * Added to USERS command in silcd/command_reply.c to join the client,
7152 we didn't use to know about, to the channel after we've created
7153 a client entry for it. Also, for clienet we did know already still
7154 check whether it is on the channel or not and add it if not.
7156 * Removed silc_server_command_join_notify as the function and its
7159 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Changed the client's pending command handling to the same as the
7162 server's pending command handling. It is also now possible to
7163 execute command reply functions from other command reply
7164 function as the function callbacks for commands and command
7165 replies are one and same. The pending commands are not static
7166 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7167 in client connection context. Thus, pending commands are server
7168 connection specific as it is convenient.
7170 Changed the function silc_client_command_pending and
7171 silc_client_command_pending_del and added new function
7172 silc_client_command_pending_check. Removed the
7173 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7176 * Added cmd_ident, current command identifier, to the client
7177 connection context in lib/silcclient/client.h to keep track on
7178 command identifiers used in command sending. Client's command reply
7179 function handling now supports the mandatory command identifiers.
7181 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7182 funtions in client to fully support pending command callbacks.
7184 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7185 as one of the arguments to the application in the command reply
7188 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7189 before first releasing SILC but came back. Now it is removed again
7190 and should come back nomore. The FORWARDED flag was used only
7191 by the JOINing procedure by forwarding the command packet to router.
7192 Now, the JOINing procedure has been changed to more generic (due
7193 to various router environment issues) and FORWARDED is not needed
7194 anymore for anything. The protocol specification is yet to be
7197 Now, removed silc_server_packet_forward from server and the flag
7198 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7200 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Renamed NAMES command to USERS command. The NAMES was named that
7203 due to historical reasons. Now it is renamed. Also, rewrote
7204 parts of the USERS command. The nickname list is not sent anymore
7205 by the server. Only Client ID and mode lists are sent in the USERS
7206 command. Changed this also to the protocol specification.
7208 The client now resolves the names and stuff after it receives
7209 the USERS list from the server when joining to the channel.
7211 * WHOIS and IDENTIFY commands has been changed to support multiple
7212 Client ID's per command. One can now search for multiple users
7213 in the network by sending only one WHOIS or IDENTIFY command.
7214 Changed the code and the protocol specifications.
7216 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7217 uses silc_server_command_whois_parse to parse the request. */
7219 * If normal server, do not parse the WHOIS and IDENTIFY requests
7220 before sending it to the router. Saves some time.
7222 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7224 * Fixed JOIN command on client library. Wrong number of arguments
7225 used to crash the client.
7227 * Added silc_server_channel_has_global function to check whether
7228 channel has global users or not.
7230 * Added silc_server_channel_has_local function to check whether channel
7231 has locally connected clients on the channel.
7233 * The silc_server_remove_from_one_channel now checks whether the
7234 channel has global users or not after given client was removed from
7235 the channel. It also checks whether the channel has local clients
7236 on the channel anymore. If it does not have then the channel entry
7237 is removed as it is not needed anymore.
7239 * The silc_server_notify now checks on JOIN notify whether the joining
7240 client is one of locally connected or global. If it is global then
7241 the channel has now global users on the channel and that is marked
7242 to the channel entry. Also, it now saves the global client to
7243 global list who is joining and JOINs it to the channel. This is
7244 for normal server, that is.
7246 Changed silc_server_send_notify_on_channel,
7247 silc_server_packet_relay_to_channel and
7248 silc_server_packet_send_to_channel check if we are normal server
7249 and client has router set (ie. global client) do not send the
7250 message to that client, as it is already routed to our router.
7252 * Implemented LEAVE notify type handling in silc_server_notify
7255 * Tested LEAVE command in router environment successfully. Tested
7256 with two routers, two servers and two clients.
7260 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7262 * Implemented SIGNOFF notify type handling in silc_server_notify
7265 * silc_server_remove_id now removes the client entry from all channels
7266 it has joined and thusly sends SIGNOFF notify type.
7268 * Rewrote the NAMES list generation in server by removing two excess
7269 loops. The lists are created now inside one loop.
7271 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7273 * silc_server_remove_channel_user checks now also global list
7274 for channel and client.
7276 * silc_server_new_channel_user checks now both local and global
7277 list for channel and client. Fixed a bug in client id decoding.
7278 Used to decode wrong buffer.
7280 * silc_server_channel_message checks now both local and global
7281 list for channel entry.
7283 * Tested channel joining (hence JOIN) in router environment
7284 successfully. Tested with two routers, two servers and two
7287 * Tested channel message sending in router environment successfully.
7289 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Added silc_server_save_channel_key into server.[ch] to save the
7292 received channel key in Channel Key payload processing. It is
7293 also used in JOIN command reply handling.
7295 Equivalent function silc_client_save_channel_key added into
7296 client.[ch] into client library.
7298 * Changed JOIN command reply to send information whether the channel
7299 was created or not (is existing already) and the channel key
7300 payload. Changed protocol specs accordingly.
7302 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7303 the request was sent by ID and not by nickname. Crashed on
7306 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7309 now correctly save the received data.
7311 * silc_server_free_sock_user_data now notifies routers in the
7312 network about entities leaving the network.
7314 At the same time implemented functions silc_server_remove_id
7315 and silc_server_send_remove_id to receive and send REMOVE_ID
7316 packets. The packet is used to notify routers in the network
7317 about leaving entities. The ID removed will become invalid in
7320 * Added function silc_idlist_del_server into server. Removes and
7321 free's server entry from ID list.
7323 * silc_server_private_message function now checks, if we are router,
7324 that the destination ID really is valid ID, naturally.
7326 * In router when NEW_ID packet is received (for new client) the
7327 hash of the Client ID is saved in the ID Cache but the
7328 client->nickname is set to NULL, instead of putting the hash
7331 IDENTIFY command now also checks that client->nickname must be
7332 valid. If it is not if will request the data from the server who
7333 owns the client. Added new function
7334 silc_server_command_identify_check.
7336 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7337 to set the command to already allocated Command Payload.
7339 * Tested private message sending in router environment with two
7340 routers, two servers and two clients. Fixed minor bugs and now
7343 * Fixed segfault from client's NAMES command. Used to crash if
7346 * Forwarded packets must not be routed even if it is not destined
7347 to the receiver. Changed server code comply with this.
7349 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Added `require_reverse_mapping' boolean value to ServerParams
7352 structure. If TRUE (not default) the server will require that
7353 the connecting host has fully qualified domain name.
7355 If the reverse mapping is not required and hostname could not be
7356 found the IP address is used as hostname.
7358 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7360 * Implemented version string checking to both client and server.
7361 The check is incomplete currently due to the abnormal version
7362 strings used in development version of SILC.
7364 * Changed all command functions in server to use the new
7367 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7369 * Changed char *data to unsigned char *data in ID Cache system to
7370 support binary data as ID Cache data. Changed code to support
7371 binary data in lib/silccore/idcache.c.
7373 * Renamed silc_server_packet_relay_command_reply to
7374 silc_server_command_reply as it is normal packet receiving
7375 function. Rewrote the function to accept command replys for
7376 servers and not only for clients.
7378 * Mark remote router always as registered server if we are connecting
7379 to it. Otherwise, commands sent by the router to us are ignored.
7381 * All ID List find routines now returns the ID Cache Entry pointer
7382 as well if requested.
7384 * WHOIS command works now in router environment, tested with two
7385 routers, two servers and two clients.
7387 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7388 in router environment (as it is almost equivalent to WHOIS) but
7389 hasn't been tested thoroughly. Added new functions:
7391 silc_server_command_identify_parse
7392 silc_server_command_identify_send_reply
7393 silc_server_command_identify_from_client
7394 silc_server_command_identify_from_server
7396 * Disabled route cache adding because adding two different ID's with
7397 same IP replaces the old cache entry thus giving wrong route.
7398 The entry->router->connection is always the fastest route anyway
7399 so route cache may not be needed. Of course, new routes maybe
7400 established after receiving the ID when the entry->router->connection
7401 might not be anymore the most optimal.
7403 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Add route cache for received ID for fast routing.
7407 * Added silc_server_packet_route to route received packet on router
7408 that is not destined to us.
7410 * Renamed silc_server_get_route to silc_server_route_get.
7412 * Added id_string and id_string_len fields into SilcServer to
7413 include encoded ServerID for fast comparing without excess
7414 encoding of the ID's.
7416 * Cleaned up WHOIS command on server side. Added following static
7419 silc_server_command_whois_parse
7420 silc_server_command_whois_check
7421 silc_server_command_whois_send_reply
7422 silc_server_command_whois_from_client
7423 silc_server_command_whois_from_server
7425 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7426 arguments in command replies. All command functions should be
7427 updated to use this macro.
7429 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7431 * Minor typo fixes on command reply handling on server.
7433 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7435 * Added silc_server_command_add_to_channel internal routine to add
7436 the client to the channel after router has created the channel and
7437 sent command reply to the server.
7439 * Added generic silc_server_send_command to send any command from
7442 * Use static buffer with ID rendering instead of duplicating data.
7444 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7446 * Fixed a channel user mode bug when joining to a channel server gave
7447 everybody channel founder rights, oops.
7449 * We mark ourselves as the router of the incoming server connection
7450 if we are router ourselves. This way we can check in some packet
7451 sending functions whether it is locally connected server. For
7452 incoming router connections we put NULL.
7454 * For router sending packets locally means now always sending the
7455 packet cell wide; to local clients and local servers. For normal
7456 server sending packet locally means sending it to only local
7459 * Fixed the JOIN command to really work in router environment. If the
7460 channel is created it is always created by the router. Router is
7461 also responsible of making the initial joining to the channel,
7462 sending JOIN notify to the sending server and distributing
7463 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7464 does not exist server doesn't do anything else but forward the
7465 command to the router which performs everything.
7467 * Added silc_server_send_channel_key function to send the Channel Key
7470 * Added silc_server_create_channel_key to create new channel key. The
7471 channel key is now re-generated everytime someone joins or leaves
7472 a channel, as protocol dictates. Note: channel->key_len is the
7475 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7478 packet_receive.[ch] to separate packet sending and receiving
7479 routines. The server.[ch] now includes everything else including
7480 actual packet processing (writing and reading data) and other
7483 Renamed silc_server_private_message_send_internal to
7484 silc_server_send_private_message. The routine is still though
7485 used only to relay private messages as server does not send
7486 private messages itself.
7488 Renamed silc_server_new_channel to silc_server_create_new_channel
7489 and added new function sicl_server_new_channel that handles the
7490 incoming New Channel packet. Added also new sending function
7491 silc_server_send_new_channel to send New Channel Payload.
7493 * Added new function silc_server_notify to process incoming notify
7494 packet to the server/router. Server may then relay the notify
7495 to clients if needed.
7497 * Added new function silc_server_new_channel_user to process incoming
7498 New Channel User packet. Router will redistribute the packet and
7499 send JOIN notify to its local clients and locally connected servers
7500 if needed. Normal server will send JOIN notify to its local client
7501 on same channel when received this packet. Added also corresponding
7502 sending function silc_server_send_new_channel_user to sent the
7505 * Added boolean route argument to send_notif_to_channel and
7506 packet_send_to_channel functions to attempt to route the packet
7507 if it is TRUE and send only locally if it is FALSE.
7509 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * silc_server_replace_id now broadcasts the received replace ID
7512 packet if it is not broadcast packet already. The router must
7513 broadcast to inform other routers about changed ID.
7515 * Added backpointer to server's router into SilcServer context in
7516 silcd/server_internal.h.
7518 * Fixed silc_server_packet_broadcast to send correct broadcast
7521 * The channel key is now distributed to the local client as soon
7522 as it is received from the router (in router environment) so that
7523 no other packet may be sent for the channel until client has
7526 * silc_server_remove_channel_user now broadcasts the received
7527 Remove Channel User packet if it is not broadcast packet already.
7528 The router must broadcast to inform other routers about removed
7531 * Added users field into SilcPacketContext that is a reference count
7532 of the context. One can increase the reference count by calling
7533 silc_packet_context_dup which is now changed to just increase the
7534 reference count instead of duplicating the data. The reference
7535 count is decresed by calling silc_packet_context_free that will
7536 free the data after the reference count hits zero.
7538 For now on the packet context and everything allocated into it
7539 (including the raw packet from network) must be freed by calling
7540 the new silc_packet_context_free function. Added also new function
7541 silc_packet_context_alloc that must be used now to allocate the
7542 context. This also means that if a routine is asynchronous from
7543 silc_[client/server]_packet_parse_type the packet context must
7544 be duplicated by calling silc_packet_context_dup. Otherwise it
7545 gets free'd after silc_[client/server]_packet_parse_type returns.
7546 Also, one must remember that if packet is duplicated then its
7547 reference count must be decresed by calling the free function as
7548 many times as it was duplicated.
7550 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7551 from both client and server.
7553 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7555 * Made joining to a channel working in router environment.
7557 * Cleaned up JOIN command on server side and create function
7558 silc_server_command_join_channel internal routine to make the
7561 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Changed silc_command_pending list to SilcDList. Also, added
7564 `ident' field to SilcServerCommandPending structure to identify
7565 the reply and to call correct callback.
7567 Added silc_server_command_pending_check function to replace the
7568 corresnponding macro. The silc_command_pending list is not
7571 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7572 to set identifier to previously allocated Command Payload. It
7573 is used to set identifier for command when resending Command
7576 * Added silc_command_payload_encode_payload to encode Command
7577 Payload buffer from SilcCommandPayload structure.
7579 * Added silc_argument_payload_encode_payload to encode Argument
7580 payload buffer from SilcArgumentPayload structure.
7582 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * Changed WHOIS command to support router connection on server side.
7585 The whois request is always sent to router unless the server is
7586 standalone server. After server has received the reply from the
7587 router will it send the reply to the client.
7589 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7590 broadcast received broadcast packet. The function is used only
7591 by router. The broadcast packet is always sent to the router's
7594 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7595 render given ID to printable string, for log files for example.
7597 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7599 * Made basic router to router connections working. At least they
7600 can now connect to each other but nothing really works the way
7601 they are supposed - yet.
7603 * Added new initiator token to RouterConnection configuration
7604 file in silcd/serverconfig.[ch]. It is used to tell whether we
7605 are the initiator to the remote router or whether we'll expect
7606 the other end to connect.
7608 * Moved registering of listener task to silc_server_init, hence
7609 the server starts listenning as soon as it is run, even if it
7610 does not have connections to other routers. Let's see how well
7613 * Changed default connection retry timeouts for more suitable in
7616 * Removed cipher and such arguments from silc_idlist_add_client
7617 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7618 Added new function silc_idlist_add_data to add the keys and stuff
7621 * Added SilcIDListData structure and added it to SilcClientEntry
7622 and SilcServerEntry as their first field in the structure. This
7623 way we can explicitly cast the ID entries to the SilcIDListData
7624 structure and get common data for the entries. In past, we had
7625 to first check what type of connection it is and then cast it to
7626 correct ID entry type. Now, we can directly cast the opaque
7627 pointer to the SilcIDListData (no matter what ID entry it actually
7628 is) and get the data needed.
7630 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7633 in some circumstances even if threre were timeout tasks, though not
7634 IO tasks, but tasks anyway. Now fixed.
7636 * Defined SilcServerConnection structure to hold connection specific
7637 stuff about directly connected servers and routers. The definition
7638 is currently in silcd/server_internal.h. I thought about having
7639 a bit more important role fro this struct but for now it is used
7640 only when connecting to other server (or router actually).
7642 * Added connecting retry support in server when connecting to
7643 router(s). The retry feature implement exponential backoff
7644 algorithm. Also, added SilcServerParams structure to hold default
7645 parameters for server. For now, it include these retry settings
7646 and are hard coded. After server is moded to be as Silc Server
7647 Library this structure will be more important.
7649 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7651 * Changed client librarys channel->clients table to SilcList and
7652 changed code accordingly.
7654 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7656 * Changed client's channel table to SilcList and changed code
7657 accordingly. Also changed SilcChannelClientEntry to include back-
7658 pointer to the channel so that client entry can use that structure
7659 as list as well and we have fast cross-reference to the channel.
7660 This change dramatically decreased the complexity of channel
7661 handling with client entry and vice versa (removed one extra
7662 loop when searching for channel entry from many functions).
7664 * Changed server->sim from table to SilcDList and changed code
7667 * NAMES command can now be used from user interface. It will show
7668 the user list on the channel, neatly.
7670 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7671 Code now saves realname of the user if it becomes available.
7673 * Renamed configure.in to configure.in.pre and made ./prepare
7674 script to automatically add correct version string to
7675 configure.in which it creates from configure.in.pre.
7677 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7679 * NAMES command reply now shows users mode with the nickname when
7682 * Moved silc_client_ch[u]mode[_char] functions from
7683 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7684 place sucks, they are utility functions and should be in some
7687 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7689 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7692 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Added TRQ (efficient deque and list library) into lib/trq. This is
7697 a very good list library that is currently used in the SILC. Defined
7698 SilcList API over the library because I didn't like the API very
7699 much. See lib/trq/silclist.h for the API and examples of how to
7700 use the API. Fixed various places in the code to use the new
7701 SilcList API. The SilcList is meant for lists that has a structure
7702 already defined as a list. It is not suitable to add just some
7703 context to the list (in TRQ, the context is the list actually).
7705 So, I defined SilcDList that can be used for the purpose where
7706 predefined list structure does not exit. This can be used as
7707 such list. Now some context just can be added to the SilcDList.
7708 Currently this list is not used in the SILC just yet, though there
7709 are a lot places where this can replace dynamically allocated
7710 tables and I will fix these places, later, to use SilcDList.
7711 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7712 and use TRQ internally).
7714 Also fixed some annoying warning messages that the original TRQ
7715 code generated. Also minor changes to TRQ's Makefile.in.
7717 * Added support for querying by Client ID to both WHOIS and
7718 IDENTIFY commands into server, as required by the protocol.
7720 * Removed method function pointers from SilcBuffer structure. They
7721 weren't used to anything and just increased the context size for
7722 no good reason. This change also made silc_buffer_alloc and
7723 silc_buffer_free functions inline functions.
7725 * Disabled command flooding detection support until it's fixed so
7726 that it accepts commands in but does not execute them more than once
7729 * Added silc_net_localhost(), to return local hostname, into
7730 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7731 that must be initialized before calling silc_client_init.
7733 * Added new function: silc_server_send_notify_on_channels to send
7734 notify messages to all channels client has joined. It is assured
7735 that the message is sent only once per client.
7737 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7738 lib/silcutil/silcutil.[ch] as silc_format function. The new
7739 function is generic and is used by server as well, not only by
7740 the logging routines.
7742 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7743 the provided version string was not acceptable. Added new function:
7744 silc_ske_check_version into lib/silcske/silcske.h. The function
7745 must be implemented by the application (client or server) and it
7746 does not reside in the SKE library. The function checks the version
7747 string remote end sent.
7749 * Added back pointers (to opaque context and to SilcSocketConnection)
7750 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7752 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7753 duplicate packet context structure.
7755 * Changed `notify' client operation to send same arguments as client
7756 receives from server except for ID's. ID's are mapped to correct
7757 ID entry and that is returned. Also, if channel entry is not sent
7758 by server but the notify is for channel the channel entry is sent
7759 to application (otherwise application doesn't know that it is for
7760 channel (library gets it from packet's Destination ID)).
7762 * Added silc_client_remove_from_channels into client library to
7763 remove a client from all channels it has joined to. Used when
7764 received SIGNOFF notify from server. Added also new function
7765 silc_client_replace_from_channels to replace old ID entry with
7766 new ID entry on all channels. Used when received NICK_CHANGE
7769 * Fixed ID Cache list handling in silc_idlist_get_client in
7770 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7771 to get (or query) client by ID.
7773 * Updated TODO list.
7775 * Added connection authentication status message defined by the
7776 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7777 support for these into the code in client and server side.
7779 * Added generic function silc_client_send_command to send any command
7780 with variable argument list. Application should use this function
7781 to send commands if the command functions provided by the library
7782 does not suite for the application's user interface needs.
7784 * Added new `failure' client operation. Application is notified about
7785 received failure packet if client is executing a protocol. In this
7786 case the protocol's execution has failed.
7788 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7789 is required by the protocol.
7791 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7792 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7795 * Added status flag to SilcSKE object to indicate realtime status
7796 of the SKE protocol.
7798 * Application receives now exactly same command reply arguments as
7799 the library receives from server. However, if ID is received the
7800 corresponding ID entry is returned to the application (eg. Client
7801 ID is mapped to correct SilcClientEntry entry and that is returned).
7802 Changed command_reply client operation due to this change.
7804 * Changed all ID's in commands and in command replys as ID Payloads.
7805 Change affected both client and server side codes.
7807 All ID's sent in SILC network (with execption of ID's in SILC
7808 Packet header) are sent in ID Payload to support variable length
7811 * Server now notifies nick changes and notifies all clients on
7812 the channels about the new nickname (about the new Client ID,
7815 * Implemented CMODE command to change channel modes. Supports all
7816 channel modes defined by the protocol specs except ban and invite
7817 lists. (Also, private channel key mode is supported but support for
7818 setting private channel key in client is missing, thus, this mode
7819 has no effect on client side (except that server requires that the
7820 client uses private channel key and normal channel traffic does not
7823 Also, invite mode works per se, but INVITE command does not work
7824 yet correctly, so you can set channel as invite only channel but
7825 inviting clients to the channel does not work (it is yet to be
7826 thought what's the best way to do it).
7828 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7829 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7830 Implemented CUMODE command to change user's mode on the channel.
7831 Supports all modes defined by the protocol specs.
7833 * Added NAMES command reply to return users modes on the channel.
7835 * Removed unnecessary and slow ciphers from lib/silccrypt.
7837 * Set SO_KEEPALIVE option to connection sockets by default.
7839 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7841 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7842 redefined the Notify Payload into protocol specs.
7844 * Added silc_id_payload_parse_id to get ID directly from raw
7847 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7849 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7850 accept searching by Client ID as well.
7852 * Added support for LEAVE and SIGNOFF notify types in client library.
7854 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7855 to parse ID Payload from raw data.
7857 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7859 * Added flags parameter into silc_ske_assemble_security_properties
7860 function in lib/silcske/silcske.[ch].
7862 * Changed notify client operation to fit better for notify messages
7863 sent by server. The notify payload received from server is now
7864 passed to the application (after parsing it to SilcNotifyPayload).
7865 It is application's responsibility to retrieve the arguments
7866 from the payload and show the message the way it wants. The message
7867 sent by server is implementation specific.
7869 * Changed public keys to comply with the protocol specification.
7870 Old public keys are not supported anymore and are not compatible.
7872 * Removed nickname from Channel Payload as the latest draft removed
7873 it. The client must resolve the nickname from the NAMES command
7874 reply received when it joined the channel.
7876 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7878 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Fixed some errors in protocol specification drafts.
7882 * Created lib/silccore/silcnotify.c to implement Notify Payload
7883 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7884 generic payloads described by protocol specifications. The file
7885 includes implementations for ID Payload and Argument Payload.
7887 * Changed Command Payload implementation to use the new Argument
7888 Payload. Changed command_xxxx_payload to command_payload_xxxx
7889 to comply with SILC coding conventions.
7891 * Added suppport for Argument Payload handling in Notify Payload
7892 implementation as protocol requires it. Added the new support
7893 into server and client lib as well.
7895 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Added support for multiple nicknames on same channel. [n] is
7898 added locally to the nickname if there are more than one same
7899 nicknames on the channel.
7901 * Server now sends all nicknames that matched WHOIS request.
7902 Client also shows the list received from server.
7904 * Added TOPIC command to client side. User can now set and show
7905 current topic on channel.
7907 * Added MOTD command to client and server. Also, server sends the
7908 motd when client connects to the server.
7910 * Changed version strings to comply ISO 8601.
7912 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7914 * Fixed protocol error handling in client library. It should now
7915 cope even if the SKE fails for some reason.
7917 * Made new protocol specification drafts for submitting to IETF.
7919 * Implemented TOPIC command to server in silcd/command.c.
7921 * Added two new notify types into lib/silccore/silcnotify.h:
7922 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7923 notify nickname change and topic setting/change on a channel.
7925 * API change of command_reply operation in client library. The
7926 application gets now the status type received from server as well.
7928 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7930 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7932 * Cras fixed and optimized the packet handling even further and
7933 it should work now. Minor change to the prototype of function
7934 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7936 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * Added new function into lib/silcutil/silcschedule.[ch]:
7939 silc_schedule_with_fd to select() a specified fd. The function
7940 returns after timeout expires or data arrives or goes. The
7941 function is used by packet routines to wait that all data is
7942 received from network.
7944 * Fixed data reading from network in lib/silccore/silcpacket.c.
7945 The code now assures that all data is read from the fd and then
7946 continues packet processing. This was a bug fix since the code
7947 used to drop some data in some circumstances.
7949 * Added new function into lib/silcclient/client.[ch]:
7950 silc_client_start_key_exchange to start key exchange after
7951 connection has been established to server. The code internally
7952 now uses this funtion but its main purpose was to provide it
7953 for applications that perform their own connecting. After
7954 application has created a connection it merely calls this
7955 function to start the key exchange between client and server.
7956 The library takes care of everything else after that.
7958 Updated also lib/silcclient/README to explain the usage of
7961 * Do not send to application information that connection has
7962 been established. Application gets notified it by connect
7965 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7967 * Applied cras's patch to add silc_schedule_one function. The
7968 function runs scheduler once and returns.
7970 * Fixed the scheduler after cras messed it up. The timeout
7971 handling works now as it's supposed to work.
7973 * Added into lib/silccore/ silcnotify.h to include notify
7974 message types support. Changed silc_server_send_notify*
7975 functions, in server.[ch], to support those new notify types.
7976 Added the support for the notify types into client library,
7977 as well. Added new notify client operation into ops.h in
7980 * Changed silc_server_packet_send_to_channel to send normal
7981 packets instead of just channel message packets. The function
7982 is now used to send the notify packets to channels. It is not
7983 used to send channel message packets anymore, as server never
7986 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7987 va_arg()s as it seems to require it nowadays. I guess, if SILC
7988 is compiled with older va_arg() the new code should work anyway.
7990 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7992 * Splitted core library. Core library (lib/silccore) includes
7993 now only SILC protocol specific core (and common) components.
7994 Created new utility library (lib/silcutil) that includes more
7995 generic purpose stuff. The stuff for util library was taken
7996 from the old core library. This was minor and easy split.
7998 * Created SILC Client Library (lib/silcclient) that includes
7999 implementation of the SILC client without user interface. This
8000 was major move from silc/ directory. The code has been changed
8001 so that it is transparent towards the user interface. The
8002 silc/ directory includes now the same user interface as before
8003 and it uses the new client library. Read lib/silcclient/README.
8004 Basicly, the client library performs everything else related
8005 to SILC except user interface handling. Also, configuration
8006 files are considered to be part of user interface and library
8007 does not handle them.
8009 This change also changed a lot of structures, function naming etc.
8010 Most important change was that SilcClientWindow object was
8011 renamed to SilcClientConnection in the client library. Created
8012 also new file lib/silcclient/ops.h. Also added new files
8013 silc/local_command.[ch] and silc/client_ops.[ch].
8015 All these changes were made to make it easier for user interface
8016 designers to create what ever user interface for the SILC client
8019 It is also expected that the server will be moved to lib
8020 directory as well and SILC Server Library will be created;
8021 sometimes in the future.
8023 * Removed Local commands from lib/silccore/silccommand.h as
8024 they are application specific and new client library does not
8025 handle any of those anymore.
8027 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8028 old client implementation in silc/.
8030 * Added support for callback functions in SILC_LOG_* macros.
8031 Application can now set its own callbacks that will be called
8032 instead of using the default functions that will always print
8033 the debug messages to stderr (or stdout). Also, debugging can
8034 now be disabled by setting silc_debug to FALSE and re-enabled by
8035 setting it to TRUE. Note, that logging will still work even
8036 if debugging is disabled.
8038 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8039 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8040 silc_log_reset_debug_callbacks.
8042 * To enable debugging in silc client one must give now -d
8043 option on command line.
8045 * Changed silc_schedule_init to automatically allocate task queues
8046 if they are not allocated before calling it.
8048 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8050 * Added GMP 3.1 into math library.
8052 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8054 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8055 a channel in SILC network. The packet is used by servers and
8056 routers to notify other routers that user has left a channel.
8057 This little feature was missing until now. Added the feature
8058 to protocol specification as well.
8060 Added functions: silc_server_send_remove_channel_user and
8061 silc_server_remove_channel_user into server.[ch].
8063 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8064 lib/silccore/silcpacket.h. However, they are not implemented
8067 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Fixed joining to a channel and sending channel messages
8070 between server and router. The channel message sending should
8071 now work inside a cell.
8073 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8075 * Fixed the private message sending between server and router.
8076 The private message sending should now work inside a cell.
8078 * Added silc_server_replace_id into server.[ch] to replace
8079 existing ID in the SILC network.
8081 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8082 and silc_idlist_replace_server_id into idlist.[ch] in server.
8084 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8086 * Fixed the server to server connections. Server can again now
8087 connect to router. Router to router connections probably does
8090 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8092 * Added dynamic protocol registering support. Now protocols can
8093 registered and unregistered on the fly. Patch by cras.
8095 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8097 * Added lib/contrib directory to hold routines that some platforms
8098 don't have but are needed by SILC.
8100 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8101 into lin/contrib to provide getopt() and getopt_long() for
8102 those who don't have it.
8104 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8106 * Added AWAY command to client. When away message is set and
8107 client receives a private message packet the client automatically
8108 replies to the sender with the away message.
8110 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8111 bug seemed to be the cause of recent problems when compiling
8114 * Added version detection support to SKE protocol specification
8115 and added the new changes to the SKE implementation as well.
8116 There were other minor changes in the SKE protocol as well.
8118 Many changes in lib/silcske/silcske.[ch] and in
8119 lib/silcske/payload.[ch].
8121 * Added ^U functionality, clear input line. Patch from cras.
8123 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Mainly small bugfixes on core library. Fixed some debugging
8126 logging and buffer overflow in silclog.c.
8128 * Updated config.sub and config.guess on the distribution tree.
8130 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8132 * Added command lagging support in server. Client may execute
8133 commands now only once in two seconds.
8135 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8137 * Optimized packet reception. MAC computation and checking is now
8138 also more optimized. A lot previously duplicated code is now
8139 used as generic by both client and server.
8141 * Fixed key pair generation in clientutil.c
8143 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8145 * Added into lib/silccore/silcbufutil.[ch] new function;
8146 silc_buffer_realloc.
8148 * Moved generic packet sending/encryption functions to
8149 lib/silccore/silcpacket.[ch] from client and server. Some
8150 rewriting of the functions.
8152 * Moved all generic packet reception/decryption functions to
8153 lib/silccore/silcpacket.[ch] from client and server. The
8154 packet processing is now much cleaner in both client and server.
8155 These were major changes in both client and server.
8157 * Created many common functions in server to do packet sending.
8158 Previously code were duplicated a lot, this has been removed
8161 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Rewrote major parts of the ID cache system. Don't know
8164 whether it is better now or not but at least the API is more
8167 * Major rewrite on ID cache stuff on client because of the ID
8168 cache API changes. Added idlist.c to client.
8170 * Also major rewrite on ID cache stuff on server as well.
8171 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8172 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8173 in hand, instead they are all put into the ID cache system now.
8174 All server_idlist_* routines uses ID cache now instead of
8175 traversing its own lists (those lists does not exist anymore).
8176 SilcIDList though still exists. Also, SilcXXXEntry's are
8179 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8181 * Finally made the SKE implementation compliant to the protocol
8182 specification. All mp integers are now binary encoded as
8183 opposed being HEX encoded.
8185 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8188 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8189 functions: silc_[encode/decode]_pem. Also added function
8190 silc_encode_pem_file to PEM encode with newlines ('\n') for
8193 * SILC public keys are now encoded either PEM or binary. Same
8194 option is for private keys as well. By default private keys
8195 are binary encoded and public keys PEM encoded. Silly HEX
8196 encoding were removed.
8198 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8199 function to create fingerprints.
8201 * Fixed a bug in SHA1; does not change the original data anymore.
8203 * Partly implemented INFO command on client and server side.
8204 Fixed CLEAR command. Changes to SERVER command; show current
8205 server(s) when giving command without arguments. Added
8206 VERSION command to client.
8208 * Added check to server that unregistered connections cannot
8209 execute commands (unless it is specificly allowed).
8211 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Fixed screen refresh.
8215 * Fixed channel joining bug from client. On some circumstances
8216 client tried to join to a channel it had already joined.
8218 * Added public key verification process into client's protocol.c.
8219 The client now verifies the public key from user and saves
8220 it into ~./silc/serverkeys/ directory.
8222 Added into: clientutil.[ch]: silc_client_verify_server_key.
8224 * Changed SKE protocol's silc_ske_initiator_finish function
8225 to accept callback function that verifies the received public
8226 key. Removed old silc_ske_verify_public_key function.
8228 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8230 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8231 silc_pkcs_private_key[_data]_set.
8233 * Made the password and public authentication more cleaner in
8234 server's protocol.c.
8236 * Removed historic and obsolete protocol `channel_auth' from
8237 both client and server.
8239 * Removed wrong way of sending command status messages from
8240 server to client in server's command.c. The old way violated
8241 protocol specification.
8243 Changes to silccore/silccommand.[ch]: removed
8244 silc_command_encode_status_payload -> not needed anymore,
8245 changed silc_command_encode_payload_va to accept extra
8246 argument on variable argument list. The argument type must
8247 now be provided to the function. Also, added new function:
8248 silc_command_encode_reply_payload_va which is same as
8249 normal command_encode_payload_va except command status type
8250 is provided as extra argument.
8252 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Added ~./silc directory handling. The directory includes the
8255 public and private keys for the client.
8257 Added silc_client_check_silc_dir, silc_client_create_identifier
8258 and silc_client_load_keys.
8260 * Implemented SILC protocol compliant public key. Added public
8261 and private key saving to and loading from files.
8263 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8264 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8265 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8266 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8267 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8269 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8270 silc_pkcs_load_[public/private]_key.
8272 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Added silc_server_get_route (route.[ch]) to get connection
8275 data for the fastest route for given ID.
8277 * Implemented INVITE command on client and server. The command
8278 were re-defined in the SILC Protocol Specification and the
8279 implementation now complies with the specification.
8281 * Implemented PING command on client and server.
8283 * Implemented NAMES command on client and server. The server side
8284 supports currently only normal server not router server yet.
8285 Some changes to NAMES definition in SILC protocol specification.
8287 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * Implemented LEAVE command on client and server.
8291 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8292 again. This change was made to the protocol as well. Server
8293 should not violate the protocol specification anymore.
8295 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8297 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8298 was tested. SOCKS4 was not but should work anyway.
