507 since they are highly implementation specific commands.
508 Updated protocol specs. Moved the old commands in
509 implementations to private range of command types. Affected
510 files are silcd/command.c, lib/silcclient/command.c and
511 lib/silcclient/command_reply.c. Protocol TODO #8.
513 * Fixed a bug in server where sending unknown command crashes
514 the server. Affected file silcd/command.c.
516 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
518 * Added SILC_PROTOCOLVERSION macro to check protocol version
519 of a socket connection. The affected file is
520 lib/silcutil/silcsockconn.h.
522 * Added better error logging in rekey protocol. Affected file
525 * Do not check public key types in SKE during rekey. Affected
526 file lib/silcske/payload.c.
528 * Fixed the rekey protocol with PFS, which was totally broken.
529 Affected file silcd/protocol.c.
531 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Some client implementations quit network by doing first LEAVE
534 and then immediately SIGNOFF (like Bombyx). We now do check
535 after a short time after LEAVE notify and check whether the
536 client is still valid after LEAVE, and if not we remove it from
537 cache. Affected file is lib/silcclient/client_notify.c.
539 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
541 * Merged version 1.1.4 of zlib. Even if it not currently in use,
542 it's good not to have security holes here.
544 * Fixed a negative refcount situtuation for the config context.
545 Affected file is silcd/serverconfig.c.
547 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
549 * ROBOdoc documented lib/silcutil/silcutil.h.
551 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
553 * Optimized even more the SilcPacketContext structure. Now
554 totally saved 16 bytes of memory per context after optimization.
555 Affected files are lib/silccore/silcpacket.[ch].
557 * Made strict checks for valid SILC IDs. Affected file is
558 lib/silccore/silcid.c.
560 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Changed the object argument for silc_cipher_register,
563 silc_hash_register, silc_hmac_register and silc_pkcs_register
564 to const. Affected files are lib/silccrypt/silccipher.[ch],
565 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
567 * Changed the silc_get_username and silc_get_real_name to
568 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
570 * Fixed the Irssi SILC Client to use the silc_get_username and
571 silc_get_real_name insted of glib routines since the glib
572 routines only corrupt stack. Fixes the Irssi SILC to work in
573 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
575 * Fixed the Irssi to not use g_get_home_dir since it crashes
576 or returns garbage on cygwin and corrupts stack. Added function
577 get_home_dir to Irssi routines. Affected files are
578 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
580 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
582 * Made some structure optimizations. SFTP memory FS MemFSEntry
583 entry structure. Optimized SilcTask structure. Optimized
584 SilcPacketContext structure.
586 Affected files lib/silcsftp/sftp_fs_memory.c,
587 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
589 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
591 * And yet again reverted back the config thing since Johnny
592 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
595 * Fixed memory leaks from config object. Affected files are
596 silcd/serverconfig.[ch].
598 * Added support for adding new connections to the server in rehash.
599 After rehash they take effect.
601 Added support for changing the maximum allowed connections in
602 rehash. The number can grow but going smaller is not supported.
604 Added function silc_server_num_sockets_by_remote to the
605 silcd/server_util.[ch].
607 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
609 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
611 * Added preliminary checking during config parsing for a valid
612 public/private key and removed further checks in the code.
613 Affected files are silcd/serverconfig.[ch], server.c.
615 * Moved functions silc_server_drop() and silc_server_daemonise()
616 from server.c to silcd.c since they are stricly related to
617 the application activity.
619 * Reverted a small part of the automatic ref/unref since
620 it caused a double unref in some situations. Affected
621 files are silcd/silcd.[ch], server.c, serverconfig.c.
623 * Added some .cvsignore files in the lib directory.
625 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Fixed silc_net_gethostbyaddr to correctly resolve by
628 address. Affected file lib/silcutil/silcnet.c.
630 * Fixed the notify relaying to client. The HMAC to be used
631 with relayed packets ws wrong and caused decryption failure
632 at the client end. Affected file is silcd/packet_receive.c.
634 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Created new branch silc_protocol_1_0_branch.
638 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
640 * Changed the silc_server_config_* routines to be SilcServer
641 independent. They are now officially application specific code
642 and not part of generic server implementation. Affected files
643 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
645 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
647 * Added automatic referencing of config context in the
648 silc_server_config_alloc, and automatic unreferencing in the
649 silc_server_config_destroy. Affected files are
650 silcd/serverconfig.[ch], silcd/silcd.c.
652 * Fixed the silc_log_quick handling in the logging routines.
653 It didn't log quickly when it was TRUE. Affected file is
654 lib/silcutil/silclog.c. Also the flush delay was set even
655 if it was 0 in config file. Affected file is
656 silcd/serverconfig.c.
658 * Added support for changing key pair of the server in rehash.
659 Affected file silcd/server.c.
661 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
663 * Fixed the TOPIC_SET notify to not cras. It changed the topic
664 too early, before getting the channel entry. Affected file
665 is silcd/packet_receive.c.
667 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
669 * Added functions silc_server_config_[ref/unref], these are used
670 to prevent that the config object is destroyed.
672 No longer directly affect global variables silc_log_quick and
673 silc_log_delay, they are first cached inside the config object
674 and then applied with silc_server_config_setlogfiles().
676 silc_server_config_set_defaults() is now internal to
677 serverconfig.c, there are no reasons to show this internal stuff
680 Affected files are silcd/serverconfig.[ch].
682 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
683 fprintf's to stderr, since some code may be executed again after
684 the server went into the background. Affected files are
687 * Added rehash support. Added function silc_server_rehash() that
688 will perform all the basic tasks of the rehashing procedure.
690 * Added command line option `-x, --hexdump'. This will enable the
691 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
692 The option `--hexdump' implies `--debug'.
694 * Fixed a bad bug in the logging APIs (silcutil library) where
695 the application would crash after calling silc_log_reset_all().
697 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
699 * Fixed the KICKED notify handling in client library to
700 correctly remove the channel and all entries from the
701 channel when I was kicked. This bug crashed the client.
703 Fixed yet another but in KICKED notify handling to remove
704 the kicked client correctly from the channel.
706 Affected file is lib/silcclient/client_notify.c.
708 * Fixed a minor bug in looking up correct client entry
709 in KICKED notify in server. Affected file is
710 silcd/packet_receive.c.
712 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
713 sources correctly to distribution. Fixes --with-gmp option.
715 * Removed the manual rehashing from ID Cache, and changed it
716 to use the SILC Hash Table's auto rehash feature. Affected
717 file is lib/silccore/silcidcache.c.
719 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
721 * Fixed a bug in the silc_client_nickname_format function that
722 handles the multiple same nickname formatting. Two clients
723 with same nickname caused problems after the first one left
724 and rejoined. It didn't format the nickname correctly.
725 Affected file is lib/silcclient/idlist.c.
727 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Don't change the topic if olod topic is same as new one.
730 Affected file is silcd/packet_receive.c.
732 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
734 * Added cross-reference support to the SILC Documentation
735 generator. All types across all HTML files are now cross-
736 referenced. Affected files util/robodoc/generator.c and
737 scripts/silcdoc/silcdoc.
739 * Added file lib/silcutil/silctypes.h to include all the
740 arithmetic type definitions and some macros. Removed
741 includes/bitmove.h and moved macros to silctypes.h.
743 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
747 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
749 * Added `type' argument to silc_id_payload_parse_id function which
750 now returns the type of the ID to the sent pointer. Affected
751 file is lib/silccore/silcid.[ch].
753 * Added check for CMODE_CHANGE notify type that mode change is
754 allowed by the sender. Affected file silcd/packet_receive.c.
756 * Added check for CUMODE_CHANGE notify type that mode change is
757 allowed by the sender. Affected file silcd/packet_receive.c.
758 Added the ID type as CUMODE_CHANGE notify type as argument
759 to the `notify' client operation. Affected files are
760 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
762 * Added function silc_client_add_server to the client library.
763 Added support for resolving also channel and server info when
764 received unknown entity in notify packet. Affected files are
765 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
767 * Added function silc_command_get_status to return the command
768 status from the command reply's argument payload. Affected files
769 are lib/silccore/silccommand.[ch].
771 * Added check for KICKED notify type that the kicking is
772 allowed by the client. Affected file silcd/packet_receive.c.
774 * Created function silc_get_input which can be used to get input
775 (echo on or off) from user on command line. Affected files are
776 lib/silcutil/silcutil.[ch].
778 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
780 * Optimized silc_server_packet_relay_to_channel function.
781 Added new function silc_channel_message_payload_encrypt which
782 can be called directly if channel message payload needs to
783 be encrypted and is already encoded (no need to call _encode
784 function). Packet relaying is now done by router without any
785 extra memory allocations. Affected files are
786 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
789 * Fixed the INVITE notify handling. It took wrong arguments
790 as invite list and invite delete. Affected file is
791 silcd/packet_receive.c.
793 * Added check for TOPIC_SET notify type that the topic change is
794 allowed by the client. Affected file silcd/packet_receive.c.
796 * Added check for INVITE notify type that inviting is allowed by
797 the client. Affected file silcd/packet_receive.c.
799 * Changed the silc_server_client_on_channel to return the
800 SilcChannelClientEntry as well. Moved the function
801 silc_server_check_cmode_rights to server_util.[ch].
802 Affected files are silcd/server_util.[ch], silcd/command.c.
804 * Added function silc_server_check_umode_rights to check whether
805 changing client's user mode is allowed. Added check for
806 UMODE_CHANGE notify type that the umode change is allowed
807 by the client. Affected files are silcd/server_util.[ch],
808 silcd/packet_receive.c and silcd/command.c.
810 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
812 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
813 ID length. It ignored that ID can be IPv6 based as well.
814 Affected file lib/silccore/silcpacket.h.
816 * Fixed the silc_id_id2str and silc_id_str2id to take the
817 IPv6 address offset's into consideration. Affecte file is
818 lib/silccore/silcid.c.
820 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Fixed the internal Unix scheduler functions to check for
823 NULL context they may receive. The affected file is
824 lib/silcutil/unix/silcunixschedule.c.
826 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
828 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
829 can specify different directory with --home command line
830 parameter. Affected files irssi/src/silc/core/client_ops.c,
833 * SILC-specific commands aren't now executed if the active server
834 isn't of SILC-type, so there won't be problems with having
835 IRC and SILC protocol support in same client. Affected files
836 irssi/src/silc/core/silc-channels.c, silc-servers.c,
839 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
841 * Improved the signal support in SILC Schedule. Added new
842 function silc_schedule_signal_call which is used by application
843 to mark a signal to be called. It is now safe to perform
844 any kind of tasks in signal callbacks since it is guaranteed
845 that the application specified signal callback is called
846 after the signal is over. Affected files are
847 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
849 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
851 * Added `name' field to SilcChannelPrivateKey to represent
852 application given name for the key. Moved also the context from
853 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
854 Added the `name' argument also to the function
855 silc_client_add_channel_private_key.
857 Added function silc_client_current_channel_private_key to set the
858 current channel private key in use.
860 Added "change" command to KEY command which can be used to change
861 the current channel private key. Bound the command also to
864 Also affected files lib/silcclient/client_channel.c,
865 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
867 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
869 * Added silc_rng_get_byte_fast function in to the
870 lib/silccrypt/silcrng.[ch].
872 * Changed the interface of silc_packet_assemble and the
873 silc_packet_send_prepare. If silc_packet_assmble is now
874 called the application does not call silc_packet_send_prepare
875 because the library will call it automatically. These
876 interfaces now also return a reference to the outgoing buffer
877 which includes the assembled packet, which the application can
878 use to encrypt the packet.
880 Affected files are lib/silccore/silcpacket.[ch],
881 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
882 silcd/packet_send.c, server_backup.c and packet_receive.c.
884 * Fixed a packet sending bug on very high load, where outgoing
885 packet queue wasn't handled correctly and packets got corrupted.
886 Affected files are lib/silcutil/*/silc*sockconn.c,
887 lib/silcclient/client.c and silcd/server.c.
889 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Added macro SILC_PACKET_DATALEN which can be used during
892 packet assembling to check whether the data to be added to
893 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
894 len is truncated until it fits it.
896 Added checks for maximum length of channel message payload and
897 private message payload also.
899 Added checks for maximum packet length in server and in
902 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
903 lib/silcclient/client.c, lib/silccore/silcchannel.c and
904 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
905 lib/silcclient/client_prvmsg.c.
907 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
909 * Added silc_server_packet_queue_purge call to the
910 silc_server_disconnect_remote to assure that all data in the
911 queue before disconnecting is sent to the network. Affected
914 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
916 * Added the deleting of server's own ID cache entry to the
917 silc_server_free function. Free also everything else that
918 has been allocated in silc_server_init. The affected file
921 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
923 * Added functions silc_parse_version_string, silc_version_to_num,
924 and silc_ske_parse_version to parse SILC protocol style version
925 strings. Affected files lib/silcutil/silcutil.[ch] and
926 lib/silcske/silcske.[ch].
928 * Added new configuration params: version_protocol, version_software
929 and version_software_vendor to specify what version the remote
930 host must at least be to be able to connect to server. The vendor
931 string can be regex matched too. Added new function
932 silc_server_connection_allowed to check maximum number of allowed
933 connections, and allowed versions for incoming connections.
934 Affected files are silcd/server.c, server_util.[ch] and
937 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
939 * Added preliminary support for signals in scheduler. The
940 signals we care about are now blocked always when the scheduler
941 is locked. This way we can synchronise the use of signal with
942 scheduler. It is guaranteed that when signal occurs the scheduler
943 is not locked, and thus new tasks can be safely added to the
946 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
947 to silc_schedule_internal_init and silc_schedule_internal_uninit.
948 Added new platform specific routines
949 silc_schedule_internal_signals_[un]block and
950 silc_schedule_internal_signal_[un]register.
952 Added new functions to SILC Schedule API:
953 silc_schedule_signal_[un]register. Each signal that application
954 is going to use should be registered to the scheduler.
956 Affected files are lib/silcutil/silcschedule.[ch],
957 lib/silcutil/*/silc*schedule.c.
959 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Check for unauthenticated client and server in the
962 silc_server_new_client and silc_server_new_server functions.
963 Affected file silcd/packet_receive.c.
965 * Added function silc_string_is_ascii to check whether given
966 string is 7-bit ASCII string. Affected files are
967 lib/silcutil/silcutil.[ch].
969 * Added function silc_id_is_valid_server_id into the
970 silcd/serverid.c and added checking for valid Server ID's in
971 silc_server_new_server. The Server ID must always be based
972 on the server's public IP address.
974 * Added logging of DISCONNECT packet message in the server.
975 Affected file silcd/server.c.
977 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * Changed all library interfaces that use Global RNG to also
980 accept SilcRng as argument. Affected files are
981 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
982 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
983 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
984 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
987 * Added function silc_pkcs_generate_key to the
988 lib/silccrypt/silcpkcs.[ch] for applications so that they
989 don't need to do pkcs->pkcs->init calls anymore.
991 * Remove SilcSocketConnection from the SFTP API since it really
992 wasn't needed there. The application has the information
993 saved in its contexts anyway and the SFTP layer doesn't need
994 know about it. Affected files lib/silcsft/silcsftp.h and
995 lib/silcsftp/sftp_[server/client].c.
997 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
998 The SilcSimContext is not SilcSim.
1000 * Fixed possible buffer overflows in silc_id_render in the
1001 lib/silcutil/silcutil.c.
1003 * On EPOC the global crypto module lists are not used at all
1004 in the crypto library. Added support for using the constant
1005 algorithm list on EPOC. Affected files are
1006 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1009 * Fixed the handling of third parameter of KICKED notify, since
1010 it was mistakenly updated to SILC Protocol 1.0 even though it
1011 is to be included in 1.1. Since it is not in 1.0 it is not
1012 mandatory, and this fix now handles it only if it is provided,
1013 and it is not error if it is not provided. Affected file
1014 lib/silcclient/client_notify.c.
1016 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1018 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1019 client. Affected file irssi/src/silc/core/client_ops.c.
1021 * Merged with Irssi 0.8.4 from irssi.org CVS.
1023 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1025 * Check for valid socket connection in client entries before
1026 sending any messages. Fixes a crash, but doesn't fix some
1027 other underlaying bug that is lurking there. Affected
1028 file silcd/packet_send.c.
1030 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>

1053 file lib/silcutil/silcutil.[ch].
1055 * Added support for specifying multiple public keys for Client
1056 connection section in server configuration file. This makes it
1057 possible to accept multiple public keys from same host, or to
1058 make a section that accepts any incoming host, and have the
1059 accepted public keys listed in the section.
1061 Added functions silc_sever_[find/get]_public_key, added the

1174 old name went against naming convention. Applications now
1175 include "silcclient.h" instead of "clientlibincludes.h".
1176 Removed includes/clientlibincludes.h, it is redundant now.
1178 * Renamed includes/version.h to silcversion.h.
1180 * Added really preliminary support for OS/2 into the util
1181 library. Only thread & mutex API is implemented, others
1182 are still to be implemented. Created the lib/silcutil/os2/

1216 * Added `user_count' to the SilcChannelEntry which now tells the
1217 number of users on the channel. The user count is now saved
1218 in normal server of global channels as well. Affected files
1219 silcd/server.c, idlist.h, packet_receive.c and command.c.
1221 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1222 include file utility functions.

1237 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1238 the SKE interface a bit.
1240 * Fixed padding problem in PKCS#1. The padding was not actually
1241 random since the random number generator was used incorrectly.
1242 This security bug affects only when encrypting with PKCS#1, and
1243 it is not currently used at all in SILC. SILC only use signing
1244 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1307 Affected files irssi/src/silc/core/silc-core.c,
1308 irssi/src/fe-text/silc.c.
1310 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1312 * Added new configuration options and blocks:
1313 keepalive_secs, reconnect_count, reconnect_interval,
1314 reconnect_interval_max, reconnect_keep_trying and

1329 the connection configuration object from the SilcServerConnection
1330 object instead of finding it during the connecting phase.
1331 Added the configuration object to SilcServerConnection struct.
1332 Affected files silcd/server_internal.h, server.c.
1334 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Add the client on channel after it was resolved at the
1337 channel message receiving, and it was not already on the
1338 channel. Affected file lib/silcclient/client_channel.c.
1340 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1356 authentication to be set at the same time.
1358 Added `prefer_passphrase_auth' setting in config file which
1359 can be used to set to prefer passwd auth if both passwd and
1360 public key is set. If not set, public key is preferred.
1361 This has effect only when being initiator (responder will try
1364 Added support for authentication with passphrase and public key
1365 at the same time. The passphrase is tried first always since
1366 it is faster to check.
1368 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1370 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1417 zero port also if the hostname is NULL because it could not
1420 Call file transfer monitor callback now also if error occurs
1421 during key agreement protocol.
1423 Changed the silc_client_file_send interface to return the
1424 SilcClientFileError instead of session id. The session ID
1425 is returned into pointer provided as argument.

1442 file lib/silcutil/silclog.c.
1444 * Fixed the channel message payload decryption in the function
1445 silc_channel_message_payload_decrypt to not modify the original
1446 buffer before it is verified that the message decrypted
1447 correctly. Otherwise, next time it is called with correct
1448 channel key it won't encrypt since the payload is corrupted.
1449 Affected file lib/silccore/silcchannel.c.
1451 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1464 the table with foreach callback. The current entry may
1465 become invalid in the callback but it was referenced after
1466 the callback returned.
1468 Do not allow auto rehashing of hash table during the
1469 silc_hash_table_foreach operation, for same reasons as it is
1470 not allowed for SilcHashTableList. Affected files are
1471 lib/silcutil/silchashtable.[ch].
1473 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1497 * Fixed a bug in hash table tarversing. While the hash table
1498 is traversed with SilcHashTableList the table must not be
1499 rehashed. It is now guaranteed that auto rehashable tables
1500 are not rehashed while tarversing the list. Also defined that
1501 silc_hash_table_rehash must not be called while tarversing
1502 the table. Added function silc_hash_table_list_reset that must
1503 be called after the tarversing is over. The affected files are
1504 lib/silcutil/silchashtable.[ch].
1506 * Changed all hash table traversing to call the new
1507 silc_hash_table_list_reset in server and in client library.
1509 * Added function silc_client_on_channel to return the
1510 SilcChannelUser entry if the specified client entry is joined
1511 on the specified channel. This is exported to application as
1512 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1520 * Fixed the WHOWAS command's reply sending to support the
1521 lists correctly. Affected file silcd/command.c.
1523 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * When sending JOIN command to router for processing the
1526 sender's old command identifier was not saved back to the
1527 sender's command context, fixed now. The affected file is
1530 * Create the key in JOIN command of the router did not return
1531 the channel key, added check for this. Affected file is
1534 * Fixed a channel ID update bug in JOIN command reply. Do
1535 not directly upgrade the ID but call the function
1536 silc_idlist_replace_channel_id if the ID was changed.
1537 Affected file silcd/command_reply.c.
1539 * Fixed memory leaks from command calling if it would fail.
1540 Affected file silcd/command.c.

1555 with server connections. Later this will be configurable
1556 in config file after new config file is done. Affected file
1559 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1561 * Fixed a crash in server related to channel announcements.
1562 Affected file silcd/server.c.
1564 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1566 * Fixed memory leaks in silc_server_create_new_channel*
1567 functions. Affected file silcd/server.c.
1569 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1570 which ID was changed. This way the router will send the
1571 user list for the channel again, and server won't be in
1572 desync in some rare circumstances. Affected file is
1573 silcd/packet_receive.c.
1575 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1577 * Check for NULL socket pointer in the function
1578 silc_server_packet_send_to_channel_real. Affected file
1579 silcd/packet_send.c.
1581 * Fixed the BAN notify handling to correctly remove ban
1582 list. Affected file silcd/packet_receive.c.
1584 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Fixed some header addition to Toolkit distribution in
1587 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1589 * Added lib/silcclient/client_ops_example.h as an template
1590 file for application programmers to quickly start using
1591 the SilcClientOperation functions in their application.
1592 Updated the lib/silcclient/README as well to tell about this
1593 nice file made available.
1595 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1597 * Call silc_server_remove_from_channels when removing client
1598 entry when NO_SUCH_CLIENT_ID was received. Affected file
1599 is silcd/command_reply.c.
1601 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1603 * Added server & router operator statistics updating. Affected
1604 file silcd/packet_receive.c and silcd/command.c.
1606 * Fixed the SERVER_SIGNOFF notify handling on normal server
1607 not to save the history information for clients. Same was
1608 fixed earlier in remove_clients_by_server function, but not
1609 here. Affected file silcd/packet_receive.c.
1611 * Raised the default connection-retry count from 4 to 7 in
1612 server. Affected file silcd/server.h.
1614 * Cancel any possible reconnect timeouts when we start the
1615 key exchange. Affected file silcd/server.c.
1617 * Do not reconnect on connection failure when SCONNECT was
1618 given. Affected files silcd/server.[ch].
1620 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1624 * Fixed the NICK command to always give the unformatted
1625 nickname to the one giving the NICK command. If unformatted
1626 nickname is cached already it will be formatted and the
1627 local entry will always get the unformatted nickname.
1628 Affected file lib/silcclient/idlist.c.
1630 * Fixed some double frees from client library commands.
1631 Affected file is lib/silcclient/command.c.
1633 * Fixed CUMODE command in server to assure that no one can
1634 change founder's mode than the founder itself, there was a
1635 little bug. Affected file silcd/command.c.
1637 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1639 * Removed the SilcClientCommandDestructor from the client
1640 libary, it is not needed anymore. Affected files are
1641 lib/silcclient/silcapi.h, command[_reply].[ch],
1642 client_notify, idlist.c.
1644 * Fixed GETKEY command to first resolve client, and then
1645 resolve the server only if the client was not found, instead
1646 of resolving both at the same time. Affected file is
1647 lib/silcclient/command.c.
1649 * Added silc_client_start_key_exchange_cb and lookup the
1650 remote hostname and IP address before starting the key
1651 exchange with server. The affected file is
1652 lib/silcclient/client.c.
1654 * The server's public key is now saved using the IP address
1655 of the server and not the servername for the filename.
1656 The hostname public key filename is checked as an fall back
1657 method if the IP address based filename is not found.
1659 Fixed the GETKEY command to save the fetched server key
1660 in correct filename.
1662 Print the remote server's hostname now when new key is
1663 received during connection process. Affected file is
1664 irssi/src/silc/core/client_ops.c.
1666 * Return always our own public key to the client if it asks
1667 for it with GETKEY command. Affected file silcd/command.c.
1669 * Removed the use_auto_addr variable from default config
1670 file since it was in wrong section. Affected file is
1673 * Fixed TOPIC_CHANGE notification to not route it when it
1674 was sent using silc_server_send_notify_to_channel function.
1675 Affected file silcd/command.c.
1677 * Fixed silc_server_send_notify_kicked to send the kicker's
1678 Client ID also, it was missing. Affected files are
1679 silcd/command.c, silcd/packet_send.[ch].
1681 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1683 * Do not save client history information in SERVER_SIGNOFF.
1684 Fixes the bug in normal server that it does not detect
1685 the client becoming valid after the server becomes back
1686 online. Affected file silcd/server_util.c.
1688 * Added `sock_error' field into the SilcSocketConnection
1689 context. When error occurs during socket operation (read
1690 or write) the error is saved. Added also new function
1691 silc_socket_get_error to return human readable socket error
1692 message. Affected files are lib/silcutil/silcsockconn.[ch],
1693 lib/silcutil/unix/silcunixsockconn.c, and
1694 lib/silcutil/win32/silcwin32sockconn.c.
1696 * The server now prints the socket error message in the
1697 signoff for client. Affected file silcd/server.c.
1699 * Fixed the `created' channel information sending from router
1700 to server in JOIN command. Checks now whether the channel
1701 really was created or not and set it according that.
1703 Fixed the JOIN command to use the client entry's current
1704 ID during the joining procedure instead of the one it sent
1705 in the command (it is checked though), since it can change
1706 between the packet processing and command processing, and
1707 would just case unnecessary pain in the client end. Affected
1708 file silcd/command.c.
1710 * Fixed a channel key payload sending to use correct channel
1711 ID when the server was forced to change the channel's ID by
1712 router. Router sent the key payload with the old Channel ID.
1713 Affected file silcd/packet_receive.c.
1715 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1717 * Call silc_server_save_channel_key only if the key payload
1718 was provided in the JOIN command's command reply. Affected
1719 file silcd/command_reply.c.
1721 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1723 * Fixed silc_mp_sizeinbase to return the value correctly with
1724 MPI. Affected file lib/silcmath/mp_mpi.c.
1726 * Fixed the stop_server signal to correctly stop the scheduler
1727 and gracefully stop the server when SIGTERM or SIGINT signals
1728 are received. Affected file silcd/silcd.c.
1730 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1732 * Simple handling of TERM and HUP signals. Also added some log
1733 flushing call around. Affected file is
1736 * Fixed small bugs in silclog.c. Now buffering output will take
1737 effect after 10 seconds since startup: This will ensure that
1738 no important startup messages are lost. Also output redirection
1739 will preserve original format ([Date] [Type] message).
1740 Affected file is lib/silcutil/silclog.c.
1742 * Added two options to the config file, in the logging section:
1743 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1744 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1746 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1748 * Do not print the warning about log files not being initialized
1749 more than once to avoid excess logging. Affected file is
1750 lib/silcutil/silclog.c.
1752 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1753 the SIM copying in make install in Makefile.am.pre.
1755 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1757 * Rewritten silclog APIs. Globally interesting changes follows:
1758 silc_log_set_files() changed to silc_log_set_file().
1759 silc_log_set_callbacks() changed to silc_log_set_callback().
1760 ROBOdoc documented silclog header file.
1761 SilcLogCb now returns bool to wether inihibit the default
1762 handler or not (to keep the old behaviour return always TRUE).
1763 The new APIs should also fix the problem of the
1764 silcd_error.log file that was written in the current directory.
1767 Log files streams will remain opened after silc_log_set_file()
1768 call, means less CPU usage notably on high traffic servers.
1769 File streams are now full buffered, and flushed to the disk
1770 every 5 minutes, lesses HD activity and CPU usage.
1771 Messages can be redirected, allowing admins to configure
1772 one single logfile for all server messages.
1773 the silc_log_quick global variable to activate fast-logging.
1774 Affected files lib/silcutil/silclog.[ch]
1776 * Changed some code to conform new silclog APIs. Affected
1777 files are doc/example_silcd.conf.in, silcd/server.c
1778 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1781 * Fixed a memory leak that could occur in some situations.
1782 Affected file silcd/serverconfig.c.
1784 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1786 * Added the silc_client_del_client to remove the client from
1787 all channels as well. Affected file lib/silcclient/idlist.c.
1789 * Fixed the client library to correctly remove the client
1790 from all channels when the client entry is being destroyed.
1791 Affected file lib/silcclient/client_notify.c, command.c.
1793 * Added auto-nicking support to the client library. If the
1794 applicatio now sets client->nickname it will be sent to the
1795 server after connecting by the library. This way for example
1796 SILCNICK (or IRCNICK) environment variables will have effect
1797 and always change the nickname automatically to whatever
1798 it is wanted. Affected file lib/silcclient/client.[ch].
1800 * Renamed silc_server_command_bad_chars to the
1801 silc_server_name_bad_chars and moved it to the
1802 silcd/server_util.[ch]. Added also new function
1803 silc_server_name_modify_bad to return nickname that
1804 includes bad characters as new nickname without those
1805 bad characters. This check and modify is now used in
1806 silc_server_new_client when the username is initially set
1807 as nickname, so it must be checked to be valid nickname.
1808 Affected file silcd/packet_receive.c.
1810 * The nickname length is now taken from the packet for real
1811 and not trusted to strlen() since it clearly can return
1812 wrong length for nickname including bad characters. This
1813 also applies to channel names. Affected file silcd/command.c.
1815 * Removed the lib/silcsilm/modules directory. Modules are now
1816 compiled into the lib/silcsim. Fixed the copying of the
1817 modules to follow symbolic links in Makefile.am.pre.
1819 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Fixed silc_string_regexify list creation. Fixes bugs with
1822 BAN and INVITE commands in server. The affected file is
1823 lib/silcutil/unix/silcunixutil.c.
1825 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1827 * Removed the command destructor entirely from the server's
1828 command and command reply routines. It is not needed, and
1829 its usage was buggy and caused crashes. Affected files are
1830 silcd/command[_reply].[ch].
1832 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1834 * Cancel protocol and NULL sock->protocol if timeout
1835 occurred during protocol. Affected file silcd/server.c.
1837 * Cancel protocol timeouts always before calling the final
1838 callback, to assure that after final callback is called
1839 no other state will be called for the protocol anymore.
1840 Affected file silcd/protocol.c.
1842 * Print error log if incoming connection configuration could
1843 not be found. Affected file silcd/server.c.
1845 * Fixed JOIN command to correctly save the founder mode
1846 to the client on normal SILC server, when the channel
1847 was created by the router. Affected file silcd/command.c.
1849 * Fixed LIST command (hopefully) to send correct reply
1850 packets. Affected file silcd/command.c.
1852 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1854 * The silc_packet_receive_process now returns FALSE if the
1855 read data was invalid packet, and TRUE if it was ok.
1857 The server now checks that if unauthenticated connection
1858 sends data and its processing fails the server will close
1859 the connection since it could be a malicious flooder.
1861 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1863 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Make sure the warning about error opening a log file is
1866 printed only once and not everytime it fails (produces
1867 too much useless log). Affected file lib/silcutil/silclog.c.
1869 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1871 * Made the silc_server_daemonise() function more readable.
1872 Affected file silcd/server.c.
1874 * Pid file is now optional, the user may comment it out from
1875 the config file. Removed define SILC_SERVER_PID_FILE, we
1876 don't need a default any longer. Affected file
1877 configure.in.pre, lib/Makefile.am.pre.
1879 * Make some use of the pid file. The server now dies at startup
1880 if it detects a valid pid file on his path. The server would
1881 die anyway in this circumstance, because of the bind() failure.
1882 Affected file silcd/silcd.c.
1884 * No longer compiling lib/dotconf.
1886 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Fixed JOIN command parsing not to crash. Affected file
1889 lib/silcclient/command.c.
1891 * Fied the NICK_CHANGE notify to add the new client entry
1892 even it is resolved. This removes an <[unknown]> nick
1893 thingy bug in the client. Affected file is
1894 lib/silcclient/client_notify.c.
1896 * Do not try to allocate 0 bytes (efence does not like it)
1897 in lib/silccore/silccomand.c when encoding payload.
1899 * Do not take IRCNICK as nickname in Irssi SILC client since
1900 it is not possible to set nickname before hand connecting
1901 the server (TODO has an entry about adding auto-nicking
1904 * Changed the silc_server_command_pending to check whether
1905 there already exists an pending entry with the specified
1906 command, command identifier and pending callback. This is
1907 to fix IDENTIFY and WHOIS related crashes that may register
1908 multiple pending commands with same identifier. Affected
1909 file silcd/command.c.
1911 * Fixed the server to reconnect to the router even if it
1912 was already reconnecting and EOF was received. This to
1913 fix a possibility that the server wouldn't ever try to
1914 auto-reconnect to the router. Affected file silcd/server.c.
1916 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Fixed the server's password authentication to use the
1919 length of the locally saved password, and not the one
1920 sent in the packet. Affected file silcd/protocol.c.
1922 * Fixed same password authentication problem in the
1923 Authentication Payload handling routines in
1924 lib/silccore/silcauth.c.
1926 * Yet another password authentication problem fixed with
1927 channel password handling in silcd/command.c.
1929 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1931 * If first character of string in silc_parse_userfqdn is '@'
1932 then do not parse it. Affected file is
1933 lib/silcutil/silcutil.c.
1935 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1937 * Fixed minor bug in IDENTIFY command reply sending, which
1938 caused various weird problems during JOIN when it was
1939 resolving names for users. Affected file silcd/command.c.
1941 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Fixed the IDENTIFY command reply sending to chech better valid
1944 clients. It was possible to send incomplete list of replies.
1945 Affected file silcd/command.c.
1947 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1949 * Added silc_client_command[s]_[un]register functions now to
1950 dynamically register the commands in client library. Removed
1951 the static table of commands. This allows the client library
1952 to call commands without causing the application to know about
1953 what commands library has called.
1955 Removed the INFO command reply kludge to detect when the command
1956 was called by library. Now library use its own command reply
1957 function for INFO command.
1959 Added function silc_client_command_call to call a command.
1960 Application can use it to call command, not access the structure
1963 Now all commands that are sent by the client library (not
1964 explicitly sent by application) use own command reply functions.
1966 Affected files around lib/silcclient/ and in
1967 irssi/src/silc/core/.
1969 * Fixed the WHOIS command reply sending to chech better valid
1970 clients. It was possible to send incomplete list of replies.
1972 Fixed the WHOIS and IDENTIFY to send the request to router
1973 if normal server did not do it and did not find any results.
1975 Affected file silcd/command.c.
1977 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Moved the internal data from SilcClient context into its
1980 own file, not accesible to application. Affected files
1981 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1982 and other files in client library.
1984 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1986 * Added doc/examples installation target in Makefile.am.pre.
1989 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1992 commands the found client entry will be removed from the
1993 cache, after notifying application about the error. Affected
1994 file lib/silcclient/command_reply.c.
1996 * Changed the /MSG to check for exact nickname user gave, and
1997 not let `nick' match `nick@host' if it is only one found. Now,
1998 user must type the exact nickname (like nick@host2) even if
1999 there are no more than one same nicks found. This is to avoid
2000 a possibility of sending nickname to wrong nickname since
2001 `nick' could match `nick@host'. Affected file is
2002 irssi/src/core/silc-servers.c.
2004 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2006 * Do not print "you are now server operator" or similar when
2007 giving /away command. Affected files are
2008 irssi/src/silc/core/client_ops.c, silc-servers.h.
2010 * Made the silc_server_command_pending_error_check to send
2011 the same command reply payload it received back to the
2012 original sender of the command. This way all arguments
2013 that was received by the server will be received by the
2014 client too. Affected file silcd/command.c.
2016 * Added the silc_idcache_add to return the created cache entry
2017 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2019 * Add global clients to expire if they are not on any channel.
2020 This is because normal server will never know if they signoff
2021 if they are not on any channel. The cache expiry will take
2022 case of these entries. This is done by normal servers only.
2023 The affected files are silcd/command_reply.c,
2024 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2026 * If server receives invalid ID notification for WHOIS or
2027 IDENTIFY and the ID exists in the lists, it is removed.
2028 Affected file silcd/command_reply.c.
2030 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2031 in client then client entry that it matches is searched and
2032 the nickname is printed on the screen for user. Affected
2033 file irssi/src/silc/core/client_ops.c.
2035 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2037 * Use cache entry expire time in the LIST command reply to
2038 purge old entries from the cache after the LIST command
2039 reply has been received. This way we don't have non-existent
2040 entries in the cache for too long. Affected file is
2041 silcd/command_reply.c.
2043 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2045 * If we are normal server, and we've not resolved client info
2046 in WHOIS or IDENTIFY from router, and it is global client,
2047 we'll check whether it is on some channel. If it is not
2048 then we cannot be sure about its validity and will resolve it
2049 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2050 file silcd/command.c.
2052 * Search channel by name (if possible) rather than by ID
2053 in IDENTIFY command's command reply. Affected file is
2054 silcd/command_reply.c.
2056 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2058 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2059 Updated specs and implemented it. Affected file silcd/command.c,
2060 silcd/packet_send.c and silcd/packet_receive.c.
2062 * Implemented the <founder auth> payload handling in the JOIN
2063 command. If provided all conditions for channel joining
2064 except requirement to provide correct passphrase can be
2065 overrided by the channel founder. Updated the protocol specs.
2066 Affected file silcd/command.c.
2068 Added support for founder auth in JOIN command in client
2069 library. Fixed the parsing of the JOIN command now to support
2070 all options as they should be. The affected file is
2071 lib/silcclient/command.c.
2073 * Optimized the WHOIS and IDENTIFY commands to send the request
2074 to router only if it includes nicknames or other names. If
2075 they include only IDs then check the local cache first before
2076 routing. Affected file is silcd/command.c.
2078 * Added channels topic announcements. Affected file is
2079 silcd/packet_receive.c and silcd/server.c.
2081 * Fixed the silc_server_send_notify_topic_set to really destine
2082 the packet to channel. Affected file silcd/packet_send.c.
2084 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2085 library. Affected file lib/silcclient/client_notify.c.

2104 * ROBOdoc documented the lib/silcske/groups.h file and a
2105 bit changed the interface for better.
2107 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2109 * Update the client entry context in the ID cache after
2110 nick change. Affected file lib/silcclient/command.c.
2111 Fixes the CUMODE command when regaining founder privileges,
2112 and a little WHOIS problem.
2114 * Fixed silc_net_gethostbyname to correctly call the
2115 inet_ntop. Affected file lib/silcutil/silcnet.c.
2117 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2119 * Added IPv6 support checking to the configure.in.pre, added
2120 also --enable-ipv6 option to override the check. Affected
2121 file configure.in.pre.
2123 * The silc_thread_create now calls the start function
2124 directly if threads support is not compiled in. Removes
2125 ugly #ifdef's from generic code. Affected files are
2126 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2128 * Added silc_net_gethostby[name/addr]_async to asynchronously

2140 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2141 routines. Added silc_net_is_ip[4/6]. Affected file is
2142 lib/silcutil/unix/silcunixnet.c. All routines that take
2143 address as argument now supports both IPv4 and IPv6 addresses.
2145 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2147 * Fixed LIST command reply sending in server. Affected file
2150 * Server now sends the kicker's client ID in the KICK notify
2151 to the kicked client. Affected file silcd/command.c.
2153 * The client library now parses the kickers client ID and
2154 UI displays it. Affected files lib/silcclient/client_notify.c
2155 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2157 * Made all payload parsing function prototypes consistent.
2158 They all take now const unsigned char * and uint32 pair as
2159 the payload data instead of SilcBuffer. Changes all around
2160 the source tree. Other unsigned char* -> const unsigned char*
2161 changes around the tree as well.
2163 * Optimized SFTP client and server packet sending not to
2164 allocate new buffer for each packet but to recycle the
2165 first allocated buffer. Affected files are
2166 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2168 * Optimized the SFTP client to use SilcList instead of
2169 SilcDList for requests, because it is faster. Affected file
2170 is lib/silcsftp/sftp_client.c.
2172 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2173 into lib/silccore/silcid.[ch].
2175 Renamed silcpayload.[ch] into silcargument.[ch].
2177 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * If client entry is deleted with active key agreement
2180 session, abort the session.
2182 The silc_client_abort_key_agreement now calls the completion
2183 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2185 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2188 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Don't use __restrict in older GCC's. Affected file is
2191 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2193 * silc_net_localhost now attempts to reverse lookup the
2194 IP/hostname. Affected file lib/silcutil/silcnet.c.
2196 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2197 command. It can be used to gain founder privileges at
2198 the same time when joining the channel.
2200 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2201 kicker's client ID as well. Updated protocol specs.
2203 Defined that the server must send SILC_COMMAND_IDENTIFY
2204 command reply with error status to client who sent
2205 private message with invalid client ID.
2207 Updated the protocol specification.
2209 * Added silc_server_send_command_reply to send any
2210 command reply. Affected file silcd/packet_send.[ch].
2212 * Added silc_id_payload_encode_data to encode ID payload
2213 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2215 * The server now send IDENTIFY command reply with error
2216 status if client ID in private message is invalid. Affected
2217 file silcd/packet_receive.c.
2219 * Save the server key file with server's IP address in
2220 the filename instead of hostname. The affected file is
2221 irssi/src/silc/core/client_ops.c.
2223 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2225 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2228 * Added libtool support for compiling shared objects in
2229 lib/silcsim. Affected file configure.in.pre and
2230 lib/silcsim/Makefile.am. Original patch by cras.
2232 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2234 * Pid file configuration, and server's config file fixes
2235 patch by toma. Updated CREDITS file.
2237 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Fixed silc_client_channel_message to not try to decrypt
2240 the message twice if it resolved the destination client
2241 information. This could cause of dropping one channel
2242 message. Affected file lib/silcclient/client_channel.c.
2244 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2247 lib/silcclient/client.c. This function is used when the SILC
2248 Client is run under some other scheduler, or event loop or
2249 main loop. On GUI applications, for example this may be
2250 desired to used to run the client under the GUI application's
2251 main loop. Typically the GUI application would register an
2252 idle task that calls this function multiple times in a second
2253 to quickly process the SILC specific data.
2255 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2257 * Fixed silc_server_drop() for dropping the supplementary
2258 groups as well, this could cause a security hole on some
2261 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2266 * Write PID file after dropping privileges. Added -F option
2267 to run server on foreground. A patch by debolaz.
2268 Affected files silcd/server.c, silcd/silcd.c.
2270 * Fixed MOTD to return the MOTD file server name. Affected
2271 file silcd/command.c.
2273 * Added INFO command reply handling to the Irssi SILC Client.
2274 Affected file irssi/src/silc/core/client_ops.c.
2276 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Fixed the silc_idcache_list_* routines to really support
2279 the dynamic list. Fixes a crash. Affected file is
2280 lib/silccore/silcidcache.c.
2282 * Fixed the LIST command reply to really call LIST command's
2283 pending callbacks. Affected file silcd/command_reply.c.
2285 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Update conn->local_entry->nickname after giving NICK
2288 command. Affected file lib/silcclient/command.c.
2290 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2292 * Added the [pid] option to the silcd configuration file
2294 Affected files: serverconfig.[ch] and silcd.c
2296 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Save fingerprint in WHOIS command reply in server.
2299 Affected file silcd/command_reply.c.
2301 * Fixed NICK commands pending callback registration.
2302 Affected file lib/silcclient/command.c.
2304 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2306 * Use ++server->cmd_ident when sending commands in server,
2307 instead of random number. Affected file silcd/command.c.
2309 * Fixed GETKEY command reply to call actually GETKEY pending
2310 command callbacks. Affected file silcd/command_reply.c.
2312 * A bit stricter check for nicknames. Check for same nickname
2313 in NICK command also. Affected file silcd/command.c.
2315 * Do not call INFO command everytime client ID changes, only
2316 during first connecting. Affected file lib/silcclient/client.c.
2318 * Set the new nickname only after successful command reply for
2319 NICK command is returned by server. Affected file
2320 lib/silcclient/command.c.
2322 * Remove nicknames from nicklist during server_signoff notify.
2323 Should fix /NAMES bit more. The affected file is
2324 irssi/src/silc/core/silc-channels.c.
2326 * Added `fingerprint' field to the SilcIDListData in the
2327 silcd/idlist.h to hold the fingerprint of the client's
2330 Send the fingerprint of the client's public key in WHOIS
2333 Affected files silcd/command.c, and silcd/idlist.[ch].
2335 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2336 create fingerprint from given data.
2338 * Show the fingerprint of the client's public key in WHOIS.
2339 Affected files irssi/src/module-formats.[ch] and
2340 irssi/src/silc/core/client_ops.c.
2342 * Format the multiple same nicknames also during JOIN and
2343 NICK_CHANGE notifys. Affected file is
2344 lib/silcclient/client_notify.c.
2346 * Do not print error on screen for invalid private message
2347 payload since it can come if someone is sending private
2348 messages with wrong key. Affected file
2349 lib/silccore/silcprivate.c.
2351 * Fixed multiple concurrent /PING crash. Affected file
2352 lib/silcclient/command.c.
2354 * Changed the wrong ID encoding. All IP addresses must be
2355 in MSB first order in encoded format. They were encoded
2356 wrong and was in LSB format. Affected files are
2357 silcd/serverid.c, lib/silcutil/silcutil.c.
2359 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2361 * Call the `connect' client operation through the scheduler
2362 in case of error. Affected file lib/silcclient/client.c.
2364 * Call the `failure' client operation even if the error
2365 occurred locally during a protocol. Affected file is
2366 lib/silcclient/protocol.c.
2368 * Added support of sending LIST command to router from normal
2369 server. This way normal server can get list of all channels
2370 in the network too. Fixed the channel list sending in the
2371 server too. Affected files are silcd/command.c, and
2372 silcd/command_reply.[ch].
2374 * Added silc_server_update_channels_by_server and
2375 silc_server_remove_channels_by_server. They are used during
2376 disconnection of primary router and in backup router protocol.
2377 Affected file silcd/server_util.[ch], silcd/server.c and
2378 silcd/server_backup.c.
2380 * Fixed channel adding to global list in IDENTIFY command
2381 reply in server. Affected file silcd/command_reply.c.
2383 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * If the incoming packet type is REKEY or REKEY_DONE process
2386 that packet always synchronously. Fixes yet another MAC
2387 failed error on slow (dialup) connections. Affected file
2388 lib/silcclient/client.c and silcd/server.c.
2390 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2392 * Call check_version SKE callback for initiator too. Affected
2393 file lib/silcske/silcske.c.
2395 * Implemented fix for security hole found in the SKE that was
2396 fixed in the specification few days back; the initiator's
2397 public key is now added to the HASH value computation.
2398 Added backwards support for the old way of doing it too, for
2399 old clients and old servers. Affected file is
2400 lib/silcske/silcske.c.
2402 * Enabled mutual authentication by default in SKE. If initiator
2403 is not providing mutual authentication the responder will
2404 force it. This will provide the proof of posession of the
2405 private key for responder. The affected files are
2406 lib/silcclient/protocol.c and silcd/protocol.c.
2408 * Do not cache anymore the server's public key during SKE.
2409 We do mutual authentication so the proof of posession of
2410 private key is done, and if the server is authenticated in
2411 conn auth protocol with public key we must have the public
2412 key already. Affected file silcd/protocol.c.
2414 * Added new global debug variable: silc_debug_hexdump. If
2415 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2416 file lib/silcutil/silclog.[ch].
2418 * Fixed compilation warning due to char * -> const char *.
2419 Affected files lib/silcutil/silcnet.h, and
2420 lib/silccore/silcauth.[ch].
2422 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2424 * Fixed CMODE command when new channel key was created. If
2425 the creation failed the old key was removed. Next time giving
2426 same command would crash the server since the old key was
2427 freed already. Affected file silcd/command.c.
2429 * Fixed the silc_server_announce_get_channels to not crash
2430 on reconnect. Affected file silcd/server.c.
2432 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Added silc_log_set_debug_string function to set a regex
2435 string to match for debug output. Only the function names,
2436 or filenames matching the given debug string is actually
2437 printed. This way it is possible to filter out those debug
2438 strings that user is not interested in.
2440 Fixed a bug in silc_string_regexify.
2442 Affected files lib/silcutil/silclog.[ch], and
2443 lib/silcutil/unix/silcunixutil.c.
2445 * Changed the -d options in both server and Irssi SILC client
2446 to take the debug string as argument. Affected files
2447 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2449 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2451 * Added silc_hash_babbleprint to create a Bubble Babble
2452 Encoded fingerprint. The encoding is developed by Antti
2453 Huima (draft-huima-babble-01.txt), and it creates human
2454 readable strings out of binary data. Affected file
2455 lib/silccrypt/silchash.[ch].
2457 * Print the babble print now in addition of fingerprint as well
2458 in Irssi SILC client. Affected files are
2459 irssi/src/fe-common/silc/module-formats.[ch],
2460 irssi/src/fe-common/silc/core/client_ops.c.
2462 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2464 * Fixed a security problem found in SKE. The initiator's
2465 public key too is now added to the HASH hash value creation
2466 which is signed by the responder to create the SIGN value.
2467 This will prevent anyone in the middle to lie to the responder
2468 about the initiator's public key. If this is done now, the
2469 man in the middle will get caught. Updated the protocol
2472 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Better installation directory handling. Configure module
2475 paths and other paths automatically to example_silc* files
2476 in doc/. A patch by toma.
2478 * Fixed compiler warning from MPI library, and from SILC RNG.
2481 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2482 It can be configured with ./configure. A patch by toma.
2484 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Find correct make to use in prepare-clean. A patch by
2487 toma. Affected file prepare-clean.
2489 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2491 * Added irssi variables use_auto_addr, auto_bind_ip,
2492 auto_bind_port and auto_public_ip.
2494 * Changed the interface for silc_client_send_key_agreement
2495 in lib/silcclient/silcapi.h
2499 irssi/src/silc/core/silc-core.c
2501 lib/silcclient/silcapi.h
2502 irssi/src/silc/core/silc-channels.c
2503 lib/silcclient/client_keyagr.c
2506 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2508 * Added silc_pkcs_public_key_compare to compare two
2509 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2511 * Check that the client who set the founder mode on the
2512 channel is the same client that is giving the founder
2513 mode to itself. It is done by comparing the saved public
2514 key (it is saved even in the authentication is passphrase).
2515 Affected file silcd/command.c.
2517 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2519 * Do not process packet for disconnected socket connection.
2520 Affected file lib/silccore/silcpacket.c.
2522 * Process the DISCONNECT packet through scheduler in the
2523 client library. Affected file lib/silcclient/client.c.
2525 * Fixed the silc_client_packet_parse to not to increase
2526 the packet sequence number if the conn->sock and the
2527 current socket connection is not same. This can happen
2528 for example during key agreement when the conn includes
2529 multiple socket connections (listeners). Affected file
2530 lib/silcclient/client.c.
2532 * The sender of the file transfer request now provides also
2533 the pointer (listener) for the key exchange protocol. If
2534 the listener cannot be created then it sends empty key
2535 agreement and lets the receiver provide the listener.
2537 Added `local_ip' and `local_port' arguments to the
2538 silc_client_file_send. If they are provided they are used,
2539 if not then it will attempt to find local IP address, if
2540 not found or bind fails then the remote client will provide
2543 Affected files are lib/silcclient/client_ftp.c and
2544 lib/silcclient/silcapi.h.
2546 * Extended the FILE SEND command to support defining the
2547 local IP and port for key exchange listener. They are
2548 optional. Affected file irssi/src/silc/core/silc-servers.c.
2550 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2552 * Defined to WHOIS command reply the sending of fingerprint
2553 of the client's public key (if the proof of posession of the
2554 corresponding private key is verified by the server).
2555 Updated to the protocol specification.
2557 * Added support of receiving the client's public key's
2558 fingerprint in command reply in client library. Affected
2559 file is lib/silcclient/command_reply.c, and
2560 lib/silcclient/idlist.[ch].
2562 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2564 * Do not send over 128 chars long nickname to the server
2565 in NICK command. Affected file lib/silcclient/command.c.
2567 * Do not send over 256 chars long channel names to the server
2568 in JOIN command. Affected file lib/silcclient/command.c.
2570 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Assure that silc_server_close_connection cannot be called
2573 twice for same socket context. Affected file is
2576 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Send error message to application if opening file for
2579 writing during file transfer fails. Affected file is
2580 lib/silcclient/client_ftp.c.
2582 Remove all file transfer sessions for a client that we're
2583 removing from ID cache.
2585 Affected file is lib/silcclient/client_ftp.c.
2587 * Fixed silc_net_addr2bin to return correct address. Affected
2588 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2590 * Fixed file transfer session removing on signoff notify.
2591 Affected file irssi/src/silc/core/silc-servers.c.
2593 * Added the SilcClientFileError to be returned in the monitor
2594 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2595 Affected file lib/silcclient/silcapi.h.
2597 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Fixed a crash in silc_client_ftp_free_sessions and
2600 silc_client_ftp_session_free_client. Affected file
2601 lib/silcclient/client_ftp.c.
2603 * Added `disabled' field in the SilcChannelEntry in the server
2604 to indicate if the server entry is disabled. Affected file
2605 silcd/idlist.h, silcd/command[_reply].c.
2607 * SILC server adds now /var/run/silcd.pid everytime it is
2608 started. Affected file silcd/silcd.c.
2610 * Added silc_server_packet_send_clients to send a packet to
2611 the provided table of client entries. Affected file
2612 silcd/packet_send.[ch].
2614 * Fixed a crash in client resolving in client_prvmsg.c in
2615 client library. Affected file lib/silcclient/client_prvmsg.c.
2617 * Do not actually remove the client directly from ID cache
2618 during SERVER_SIGNOFF, but invalidate it. This way we
2619 preserve the WHOWAS info for the client. Affected file
2620 silcd/server_util.c.
2622 * Fixed SERVER_SIGNOFF notify handling in the server. The
2623 server is now able to process incoming SERVER_SIGNOFF notify
2624 for a server that it doesn't even know about. It will remove
2625 the clients provided in the notify. Affected file
2626 silcd/packet_receive.c.
2628 * Check for partial packet in data queue after every packet that
2629 was found from the queue. Return and wait for more data if
2630 there is partial data in queue. Affected file is
2631 lib/silccore/silcpacket.c.
2633 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2641 * Check that newsize in silc_buffer_realloc is larger than
2642 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2644 * Added better monitor of file transfers. It now monitors
2645 key agreement protocol during the file transfer too. Added
2646 error reporting too. Affected files
2647 irssi/src/silc/core/silc-servers.c,
2648 irssi/src/fe-common/silc/module-formats.[ch].
2650 * Wrote a help file for FILE command.
2652 * Added silc_rng_global_get_byte_fast to get not-so-secure
2653 random data as fast as possible. Random data is read from
2654 /dev/urandom if available and from the SILC RNG if not
2655 available. It is used in padding generation. Affected file
2656 lib/silccrypt/silcrng.[ch].
2658 * All packets in client library are now processed synchronously.
2659 Optimized packet processing a lot. Affected file
2660 lib/silcclient/client.c.
2662 * All server connection packets are processing synchronously
2663 now in server, to optimize packet processing. Affected file
2666 * Include files are installed now only in Toolkit distribution
2667 if make install is given. Affected files: all Makefile.am's.
2669 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * Assure that silc_client_notify_by_server_resolve does not
2672 resolve the client information multiple times. If it cannot
2673 be found by the first it cannot be found at all. Affected
2674 file lib/silcclient/client_notify.c.
2676 * Fixed WHOWAS command reply calling. Affected file
2677 lib/silcclient/command_reply.c.
2679 * Removed all references to silc_idlist_get_client from the
2680 Irssi SILC client since that call is internal call used by
2681 the library. The Irssi SILC client will use now client
2682 retrieval functions found in silcapi.h.
2684 * Fixed a bug in resolving nickname info before sending
2685 private message. It used freed memory. Affected file
2686 irssi/src/silc/core/silc-servers.c.
2688 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Assure my_channels statistics cannot go negative in server.
2691 Affected files silcd/server.c, silcd/server_util.c.
2693 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2707 * Added silc_net_localip to return local host's IP address.
2708 Affected file lib/silcutil/silcnet.[ch].
2710 * If key exchange or rekey protocol is active for a connection
2711 parse all packets syncronously since there might be packets
2712 in packet queue that we are not able to process without first
2713 processing packets before them. Affected file silcd/server,
2714 lib/silcclient/client.c.
2716 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2717 whether library should continue processing the packet.
2718 Affected file lib/silccore/silcpacket.h.

2759 file irssi/src/silc/core/silc-channels.c.
2761 * Added SilcClientStatus field to the SilcClientEntry in the
2762 lib/silcclient/idlist.h.
2764 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2765 is incomplete and is being resolved, it won't be resolved
2768 Make sure also that USERS command reply does not resolve
2769 twice information. Affected file is
2770 lib/silcclient/command_reply.c.
2772 Make sure that silc_client_get_clients_by_list does not
2773 resolve twice same information.
2775 * Check for valid client->id in the silc_server_free_client_data.
2776 Affected file silcd/server.c.
2778 * Fixed /GETKEY nick@server not to crash if the server entry
2779 is not found. Affected file lib/silcclient/command.c.
2781 * Fixed the silc_server_check_cmode_rights to check the
2782 requested modes correctly. Affected file silcd/command.c.

2787 Affected file silcd/command.c.
2789 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Call the silc_server_udpate_servers_by_server in the
2792 primary router that comes back online in the backup resuming
2793 protocol. Otherwise it routes packets wrong. Affected file
2794 silcd/server_util.[ch], silcd/server_backup.c.
2796 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2798 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2799 lib/silcutil/silcbuffmt.[ch].
2801 * Redefined the SILC packet header to include the padding
2802 length. Affected file lib/silccore/silcpacket.[ch].
2804 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2805 length for maximum padding up to 128 bytes). Affected
2806 file lib/silccore/silcpacket.h.
2808 * Removed all backwards support for old 0.5.x MAC thingies.
2809 The SILC packet header change makes it impossible to be
2810 backwards compatible.
2812 * Send the ENDING packet with timeout in the backup resuming
2813 protocol. This is to assure that all routers has connected
2814 to the primary router. Affected file silcd/server_backup.c.
2816 * Changed the RNG to take the first IV from random data. It
2817 used to take it from zero actually. Changed the RNG also
2818 to use /dev/urandom during session. /dev/random is used
2819 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2821 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Changed the SILC packet header to have the first two bytes
2824 (the packet length) encrypted. Affected files aroung the
2825 code tree, lib/silccore/silcpacket.[ch]. Removed the
2826 SilcPacketCheckDecrypt callback. It is not needed anymore
2827 since the silc_packet_receive_process will determine now
2828 whether the packet is normal or special.
2830 * Implemented the unidirectional MAC keys. Affected files
2831 lib/silcske/silcske.c, silcd/protocol.c and
2832 lib/silcclient/protocol.c.
2834 * Implemented the packet sequence number to the MAC computation.
2835 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2836 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2837 lib/silcclient/protocol.c.
2839 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Allow backup router to announce servers. All servers
2842 announced by backup router are added to the global list
2843 automatically. Update hte server's socket to our primary
2844 router also when backup router announces a server.
2845 Affected file silcd/packet_receive.c.
2847 * Do not update the client->router in the function
2848 silc_server_udpate_clients_by_server if the client is on
2849 global list. We might fail to find any specific server
2850 for locally connected clients and local cell clients. They
2851 should still use the `from' and not `to' as client->router.
2852 This fixes backup router resuming protocol. Affected file
2853 silcd/server_util.c.
2855 * Decrease channel statistics count only if the channel
2856 deletion worked. Affected files are silcd/server.c and
2857 silcd/server_util.c.
2859 * Added silc_server_update_servers_by_server to update origin
2860 of all server entries. Used during backup router protocol.
2861 Affected files silcd/server_util.[ch], silcd/server.c. and
2862 silcd/backup_router.c.
2864 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2865 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2866 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2867 lib/silccrypt/silchmac.c.
2869 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Assure that router cannot reroute the same channel message
2872 to the sender. Affected file silcd/packet_receive.c.
2874 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Made better checks that the channel message is not sent
2877 to the router it came from. Affected file is
2878 silcd/packet_send.c. Fixed memory leak too.
2880 * Announce informations for incoming router connection, but
2881 only after checking if it is replaced by backup router.
2882 Affected file silcd/packet_receive.c.
2884 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Fixed the backup resuming protocol to work in multiple
2887 router environment. Affected file silcd/server_backup.c.
2889 * Route packet only to one router in the function
2890 silc_server_packet_send_to_channel. Affected file is
2891 silcd/packet_send.c.
2893 * Fixed silc_server_send_notify_dest to set the broadcast
2894 flag. Fixed the silc_server_send_notify_topic to actually
2895 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2896 Affected file silcd/packet_send.c.
2898 * Changed the SFTP Filesystem interface. Changed the
2899 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2900 the filesystem operation function. The SilcSFTPFilesystem
2901 is now a context that is allocated by all filesystem allocation
2902 functions and it already includes the operations structure
2903 and filesystem specific context. It is given as argument
2904 now to the silc_sftp_server_start. This made the interface
2905 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2906 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2908 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Changed the backup router adding and getting interfaces
2911 in the server. The router that will be replaced by the
2912 specified backup router is now sent as argument. Affected
2913 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2916 * Added silc_net_addr2bin_ne to return the binary form of
2917 the IP address in network byte order. Affected files
2918 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2920 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Check for existing server ID in silc_server_new_server
2923 and in silc_server_connect_to_router_final and remove the
2924 old entry if it exists. Affected file silcd/packet_receive.c,
2927 * Send the channel message always to only one router, either
2928 in upstream or downstream. Affected file is
2929 silcd/packet_send.c.
2931 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Wrote the definition of the backup resuming protocol to the
2934 protocol specification.
2936 * Removed one redundant channel key generation from normal
2937 server during joining procedure. Removed one redundant
2938 channel key sending from server to router during joining
2939 procedure. Affected file silcd/command.c.
2941 * Made minor bugfixes to the backup router resuming protocol.
2942 Affected file silcd/server_backup.c, server.c.
2944 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Added --disable-asm configuration option. Affected files
2947 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2950 * Implemented the backup resuming protocol that is used to
2951 resume the primary router position in the cell after the
2952 primary router comes back online. Affected files
2953 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2954 and silcd/server_util.[ch].
2956 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Sleep two (2) seconds after sending QUIT command to server.
2959 Affected file lib/silcclient/command.c.
2961 * Assure that if outgoing data buffer is pending do not force
2962 send any data. Affected file silcd/packet_send.c.
2964 * Assure that if outgoing data buffer is pending do not force
2965 send any data. Affected file lib/silcclient/client.c.
2967 * Implemented the backup router support when the primary router
2968 goes down. The servers and routers can now use the backup
2969 router as new primary router without loosing connectivity.
2971 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2974 in the server to indicate disabled entry. All data read
2975 from the connection will be ignored and no data is sent
2976 for entry that is disabled. Affected files are
2977 silcd/idlist.h, silcd/server.c.
2979 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Created SFTP client and server test programs in the
2982 lib/silcsftp/tests directory.
2984 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Implemented memory filesystem (virtual filesystem) for
2987 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2990 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Implemented the SFTP (SSH File Transfer Protocol) to the
2993 lib/silcsftp. It includes SFTP client and SFTP server
2996 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2998 * Moved lib/silccore/silcprotocol.[ch] to the
2999 lib/silcutil library.
3001 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3002 take variable argument list pointer as argument. Affected
3003 file lib/silcutil/silcbuffmt.[ch].
3005 * Added silc_buffer_set function that is used to set data
3006 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3007 Affected file lib/silcutil/silcbuffer.h.
3009 * Changed various routines in the core library to use the new
3010 silc_buffer_set instead of allocating new buffer only for
3013 * Added 64-bit value formatting and unformatting support to the
3014 silc_buffer_[un]format routines. Affected file is
3015 lib/silcutil/silcbuffmt.[ch].
3017 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3018 to includes/bitmove.h.
3020 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Fixed channel user mode saving in client library. Affected
3023 file lib/silcclient/command[_reply].c.
3025 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Defined the file transfer to the SILC Protocol. Added
3028 new packet type SILC_PACKET_FTP and defined File Transfer
3029 Payload. The mandatory file transfer protocol is SFTP
3030 (SSH File Transfer Protocol). Affected file in addition
3031 of the internet draft is lib/silccore/silcpacket.h.
3033 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3034 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3035 is used as part of backup router protocol when the primary
3036 router of the cell is back online and wishes to resume
3037 the position as primary router.
3039 * Redefined the MAC generation keys in the protocol. The
3040 same key is not used anymore in both direction. Both
3041 direction will now use different keys for sending and
3042 receiving. This fixes a potential security flaw. This
3043 change causes incompatibilities in the protocol.
3045 * Redefined also the MAC computation from the packet.
3046 An packet sequence number is now added to the MAC
3047 computation. This prevents possible replay attacks against
3048 the protocol. This change too causes incompatibilities
3051 Added `sequence' field to the SilcPacketContext to hold
3052 the current sequence number for the packet.
3054 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3056 * Added `created' field to the SilcIDListData in the file
3057 silcd/idlist.h to indicate the time when the entry was
3060 * Added `created' field to the SilcChannelEntry too. Affected
3061 file silcd/idlist.h.
3063 * Added `creation_time' aguments to all the announcement functions
3064 in the server. If it is provided then only the entries that
3065 was created after the provided time frame are actually
3066 announced. Affected file silcd/server.[ch].
3068 * The protocol says that the Channel ID's IP address must be
3069 based on the router's IP address. Added check for this in
3070 the silc_server_new_channel when processing incoming New Channel
3071 Payload. Affected file silcd/packet_receive.c.
3073 * Print out the correct version with --version in SILC client.
3074 Affected file irssi/src/silc/core/silc-core.c.
3076 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3078 * Fixed WHOWAS command to check for completnes of the client
3079 entry always, not just when the command is coming from client.
3080 Affected file silcd/command.c.
3082 * Added new function silc_server_packet_queue_purge to purge the
3083 outgoing data queue to the network. After the function returns
3084 it is guaranteed that the outgoing packet queue is empty.
3085 Affected file silcd/packet_send.[ch].
3087 * Purge the outgoing packet queue in the rekey protocol's final
3088 callback to assure that all rekey packets go to the network
3089 before quitting the protocol. Affected file silcd/server.c.
3091 * Added silc_client_packet_queue_parse as similar function as
3092 in server to the client library. The affected file is
3093 lib/silcclient/client.c.
3095 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3097 * Splitted silcd/server.c and created silcd/server_util.[ch]
3098 for utility functions.
3100 * Added new socket flag SILC_SF_DISABLED to indicate that the
3101 connection is open but nothing can be sent to or received from
3102 the connection. Affected file lib/silcutil/silsockconn.[ch].
3103 The checking for disabled socket is checked in the low level
3104 silc_socket_write and silc_socket_read functions.
3106 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * Allow only nicknames and channel names that fits into the
3109 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3111 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * When processing JOIN command reply in server check that if
3114 the channel exists in our global list we'll move it the local
3115 list. Affected file silcd/command_reply.c.
3117 * Fixed the check whether client is joined on the channel already
3118 in JOIN command. Affected file lib/silcclient/command.c.
3120 * Fixed the JOIN command reply to check whether the channel
3121 already exists. Affected file lib/silcclient/command_reply.c.
3123 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Added silc_ske_status_string to map the SKE error numbers
3126 to readable strings. The affected files are
3127 lib/silcske/silcske[_status].[ch].
3129 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3131 * Do not show the private channels on the WHOIS channel list
3132 as it is not allowed by the protocol. The affected file is
3135 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Assure that the packet length digged from the actual packet
3138 is something sensible in the silc_packet_decrypt_rest_special
3139 in lib/silccrypt/silcpacket.c.
3141 * Free and NULL the allocated pointer in silc_hmac_alloc if
3142 the HMAC allocation fails. The affected file is
3143 lib/silccrypt/silchmac.c.
3145 * Print the selected security properties to the log files in
3146 the server. Affected file silcd/protocol.c.
3148 * Add SKE's reference counter even if calling the completion
3149 callback manually. Otherwise it goes negative, although it
3150 does not cause any problems. The affected file is
3151 lib/silcske/silcske.c.
3153 * Remove the client entry with short timeout after giving the
3154 KILL command. Affected file lib/silcclient/command.c.
3156 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3157 case all found clients are already disconnected (WHOWAS would
3158 found them) in the server. Affected file silcd/command.c.
3160 * Update the last_receive (time of last data received) to be
3161 updated only when received private or channel message so that
3162 the idle time showed in WHOIS makes more sense.
3164 * Added boolean field `valid' in to the SilcClientEntry in the
3165 client library to indicate whether the entry is valid or not.
3166 This fixes the nickname change bug on channel when changing
3167 the nickname to be same than the old (like nick to Nick) the
3168 nickname formatter doesn't set the new nick anymore to Nick@host.
3169 Affected file lib/silcclient/idlist.[ch].
3171 * Now actually fixed the nickname changing on disconnection.
3172 Added new function silc_change_nick to the Irssi SILC Client.
3173 Affected file irssi/src/silc/core/client_ops.c,
3174 irssi/src/silc/core/silc-nicklist.[ch].
3176 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * Check that the public key exists in the GETKEY command before
3179 trying to encode it. Affected file silcd/command.c.
3181 * Print some notifications on received public keys with GETKEY
3182 command in the Irssi SILC Client. Affected files are
3183 irssi/src/fe-common/silc/module-formats.[ch],
3184 irssi/src/silc/core/client_ops.c.
3186 * Use IDENTIFY command to resolve the server information in the
3187 GETKEY command instead of INFO command. Affected file
3188 lib/silcclient/command.c.
3190 * All command reply functions in the client library now calls
3191 the pending command reply callbacks even if an error has
3192 occurred. The server has done this a long time and now it was
3193 time to move the client library to this as well. Now all
3194 errors can be delivered back to the pending command reply
3195 callbacks if necessary. Affected files are
3196 lib/silcclient/command[_reply].[ch].
3198 * Change the nickname on disconnection back to the username
3199 because in reconnect the server will enforce it to it anyway.
3200 Affected file irssi/src/silc/core/silc-servers.c.
3202 * Fixed a config file parsing bug in the Irssi SILC client.
3203 Affected file irssi/src/silc/core/clientconfig.c.
3205 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * When printing the channel mode on JOIN, verify that the
3208 channel key and channel's HMAC are valid. Affected file
3209 irssi/src/silc/core/client_ops.c.
3211 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3213 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3214 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3215 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3217 * Removed channel key rekey task deleting from the function
3218 silc_server_save_channel_key. Affected file silcd/server.c.
3219 Added explicit timeout task context instead that is used to
3220 delete the task if we are registering a new task before the
3221 new task has elapsed.
3223 * When channel key rekey occurs the client library now saves
3224 the old channel key for a short period of time (10 seconds) and
3225 is able to use it in case some is still sending channel
3226 messages encrypted with the old key after the rekey. Affected
3227 file lib/silcclient/[idlist.h|client_channel.c].
3229 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3231 * Added check to the silc_server_new_id_real to not accept
3232 new ID if it is the sender's own ID. Affected file is
3233 silcd/packet_receive.c.
3235 * Assure that we do not announce ourself or the one we've
3236 sending our announcements when we're router and are announcing
3237 servers to our primary router. Affected file silcd/server.c.
3239 * Fixed silc_server_command_identify_check_client to assemble
3240 correct WHOIS packet. It send corrupted WHOIS packet and
3241 caused problem with router to router connections. Affected
3242 file silcd/command.c.
3244 Fixed also silc_server_command_whois_check the same way
3245 as for the IDENTIFY command.
3247 * Added new SilcIDListStatus to the server in the SilcIDListData
3248 structure. The status now includes the current status of
3249 the entry (like registered, resolved etc.). Affected file
3250 silcd/idlist.[ch]. Defined a bunch of different status types
3251 as well. This replaced the old boolean registered field as well.
3253 Added resolve_cmd_ident field to the SilcClientEntry structure
3254 too so that if the entry is for example being resolved so
3255 another command may attach to the same pending command reply
3256 without requiring to resolve the same entry again. This concept
3257 should optimize the WHOIS and the IDENTIFY resolving under
3258 heavy load by taking away unnecessary resolving for entries
3259 that are being resolved already.
3261 Added support for adding multiple pending commands for one
3262 command idenfier. Affected file silcd/command[_reply].[ch].
3264 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3265 before deleting the data. Otherwise the hash table will have
3266 freed data in comparison functions. Affected file is
3267 silcd/command_reply.c.
3269 * Fixed silc_idlist_replace_client_id to add the new entry to
3270 the cache with NULL nickname. Otherwise there will be invalid
3271 memory as the nickname after the nickname is freed. Affected
3272 file silcd/packet_receive.c.
3274 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3275 saved into wrong slots because the previous number of entries
3276 was not taken into account. Affected file silcd/idlist.c.
3277 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3279 * If we are router and we receive JOIN notify to a channel that
3280 does not have any users then notified client is marked as the
3281 channel founder, as it is it. The affected file is
3282 silcd/packet_receive.c
3284 * Added to the extended hash table API's table_del_*ext functions
3285 the destructor as argument too, so that the caller can decide
3286 which destructor to use or whether to use destructor at all.
3287 Affected file lib/silcutil/silchashtable.[ch].
3289 * Fixed ID Cache purging. It actually deleted the entries from
3290 the hash table after the data was freed. The hash table ended
3291 up comparing freed memory. The affected file is
3292 lib/silccore/silcidcache.c.
3294 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Fixed Irssi SILC client's KILL command's HELP syntax.
3298 * The USERS command now resolves the detailed user information
3299 if the userinfo field is missing. Affected file is
3300 lib/silcclient/command_reply.c.
3302 * Do not print error in silc_file_read if the read file does
3303 not exist. Just silently return NULL. Affected file is
3304 lib/silcutil/silcutil.c.
3306 * Fixed the silc_log_output to not wine about NULL filename
3307 and to not create some bogus " " filename. Affected file is
3308 lib/silcutil/silclog.c.
3310 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Fixed various printing bugs on the user interface in the
3313 Irssi SILC Client. Minor changes that were forgotten from
3316 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Fixed the configure.in.pre and the compilation and distribution
3319 environment to support the new autoconf 2.52. That version is
3320 now required to compile the CVS trunk.
3322 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3324 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3325 to generally parse user@fqdn format strings. Affected file
3326 lib/silcutil/silcutil.c.
3328 * Added nickname_format and nickname_force_format fields to the
3329 SilcClientParams structure. The first one defines the format
3330 for the nicknames that the library will enforce if the receives
3331 multiple same nicknames. The second one is boolean value and
3332 can be used to force the library to always enforce the format
3333 to the nicknames regardles whether there are multiple nicknames
3334 or not. This configurable formatting was employed to flexibly
3335 support accessing multiple nicknames from the user interface.
3336 The userinterface can now set the nicknames to what ever format
3337 they prefer. Affected file lib/silcclient/silcapi.h.
3339 Added function silc_client_nickname_format to the file
3340 lib/silcclient/idlist.c. It performs the nickname formatting.
3342 Added new field `hostname´ to the SilcClientEntry context.
3343 It holds the hostname of the client. Affected file is
3344 lib/silcclient/idlist.h.
3346 * Irssi SILC Client sets the nicknames in nick@hostn format.
3347 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3348 irssi/src/silc/core/silc-core.c.
3350 The WHOIS printing now also shows both the real nickname and
3351 the formatted nickname so that user knows how to access the
3352 user if there are multiple same nicknames cached. Affected
3353 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3354 printing formatting too to take the hostname now as a separate
3355 argument. The Affected file is
3356 irssi/src/fe-common/silc/modules-formats.[ch].
3358 * Changed the silc_client_get_clients_local to accept the formatted
3359 nickname as argument. It accepts the real nickname too but the
3360 formatted nickname can be used to find the true entry from
3361 multiple entries. Affected file lib/silcclient/silcapi.h and
3362 lib/silcclient/idlist.c.
3364 * Added nickname_format_parse field to the SilcClientParams.
3365 It is a callback function provided by the application to parse
3366 the nickname out of the formatted nickname string. The library
3367 calls it to get the nickname from the formatted string. Since
3368 the application generally knows better the format of the nickname
3369 string it parses it instead of the library, even though library
3370 encodes the formatted string. If the callback function is not
3371 provided then the library will use the string as is. The
3372 affected file is lib/silcclient/silcapi.h.
3374 * All the nickname strings passed to the client library in
3375 commands are now expected to be formatted nickname strings.
3376 If the command does not support the formatted nickname string
3377 it will assume that the sent string is the actual nickname.
3378 Affected file lib/silcclient/command.c.
3380 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Added public key authentication support to OPER and SILCOPER
3383 commands in the client library. Affected file is
3384 lib/silcclient/command.c.
3386 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Changed the get_auth_methdod client operation to be asynchronous.
3389 It can be async if the application resolves the authentication
3390 method from the server during the negotiation. Added new
3391 SilcGetAuthMeth completion callback that the application will
3392 call after resolving the authentication method.
3394 Added function silc_client_request_authentication_method that
3395 the application can use to resolve the authentication method
3396 from the server. Added also SilcConnectionAuthRequest callback
3397 that the library will call after the server has replied. The
3398 application can call this function if it does not know the
3399 current authentication method.
3401 Affected files are lib/silcclient/client.c and
3402 lib/silcclient/silcapi.h.
3404 * The Irssi SILC client now automatically resolves the authentication
3405 method incase any configuration information is not present (and
3406 currently there never is). The affected file is
3407 irssi/src/silc/core/client_ops.c.
3409 * Fixed public key authentication from the client library.
3410 Affected file lib/silcclient/protocol.c. Changed also the
3411 protocol specification about the public key authentication in
3412 the connection authentication protocol. The actual data to be
3413 signed is now computed with a hash function before signing.
3415 * Fixed the public key authentication from the server as well.
3416 Affected file silcd/protocol.c.
3418 * Removed the mlock()'s from the memory allocation routines.
3419 Affected file lib/silcutil/silcmemory.c. The ./configure does
3420 not check anymore for the mlock(). Affected file is
3423 * Fixed USERS command in server to allow the execution of the
3424 command for private and secret channels if the client sending
3425 the command is on the channel. Affected file silcd/command.c.
3427 * Fixed silc_client_get_clients_local to return the clients
3428 count correctly. It could return wrong value. Affected file
3429 lib/silcclient/idlist.c.
3431 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3433 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3434 types. The assembler optimizations seemed not to like 64-bit
3435 data types. The assmebler optimizations thus are now enabled
3436 also for BSD systems as opposed to only enable them for Linux.
3438 * Do not check for threads at all on BSD systems. Affected
3439 file configure.in.pre.
3441 * Removed -n and -h options from the Irssi SILC Client since
3442 they are not used in silc.
3444 * Fixed the prime generation to assure that the first digit
3445 of the generated random number is not zero since our conversion
3446 routines does not like number strings that starts with zero
3447 digit. If zero digit is seen the random number is regenerated.
3448 This caused some corrupted RSA keys when the zero first digit
3449 was met. Affected file lib/silcmath/silcprimegen.c.
3451 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3453 * Fixed WIN32 configuration in the ./configure script.
3454 Fixed to include xti.h on environments that has it.
3455 Patches by Carsten Ilchmann and andrew.
3457 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Changed the silc_id_create_client_id to be collision
3460 resistant. It is now assured that there cannot be created
3461 two same client ID's. I suspect that some weird bugs in
3462 the server were actually caused by duplicate Client IDs.
3463 Affected file silcd/serverid.[ch]. A router receiving
3464 new ID now also assures and informs the sending server
3465 if the ID caused collision.
3467 * Changed the silc_id_create_channel_id to also assure that
3468 there are no collisions.
3470 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Statement about ignoring the Mutual Authentication flag when
3473 performing rekey with PFS was a bit misleading. It is ignored
3474 if it was set in the initial negotiation, it cannot be even
3475 set in the rekey. Fixed in the ke-auth draft. Started the
3476 new versions of the protocol drafts in the doc/.
3478 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Fixed a bug in silc_client_command_identify_save when saving
3481 new channel information. The channel name was no duplicated
3482 and caused crash on exit. Affected file is
3483 lib/silcclient/command_reply.c.
3485 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Fixed the getkey command handling in the server. Send just
3488 empty OK reply to the sender if the key could not be fetched
3489 (but everything else was ok, like the key just was not available).
3490 Changed the public key parameter to optional in the protocol
3491 specs so that empty OK reply can be sent. Affected file
3494 Added a message to Irssi SILC client to tell to user if the
3495 server did not return a public key.
3497 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3499 * Fixed a channel key regeneration bug. It registered new
3500 timeout tasks exponentially until all system resources were
3501 used. Affected file silcd/server.c.
3503 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Added the SILC Document generator to the scripts/silcdoc.
3506 It can be used to generate the Toolkit Reference Manual out
3507 of the source tree. Internally it will also use the RoboDoc
3508 generator now imported in util/robodoc.
3510 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Added couple of return's in rekey protocol if error orccurred
3513 during the protocol. The execution must be terminated.
3514 Affected file silcd/protocol.c. Also, terminate the protocol
3515 always with timeout.
3517 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3519 * The client's Client ID was created initally from the wrong
3520 nickname (it could have been in format nick@host) in the
3521 silc_server_new_client. Affected file silcd/packet_receive.c
3523 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Added some SILC_LOG_ERROR's to various error conditions
3526 if client could not be added to ID cache. Affected files
3527 silcd/packet_receive.c and silcd/server.c.
3529 * When client's sock->user_data is freed, NULL also the
3530 client->router and client->connection pointers. Added check
3531 for these pointers being NULL to various places around the
3532 code. Affected file silcd/server.c.
3534 * Added client->data.registered == TRUE checks to various
3535 places around the code to assure that unregistered client's
3536 are not handled when it is not allowed. Affected file
3539 * Added `bool registered' fields to all
3540 silc_idlist_[server|client]_get_* routines to indicate whether
3541 the fetched client needs to be registered or not. Affected
3542 file silcd/idlist.[ch].
3544 * Add your own entry as registered to the ID cache in the
3545 server. Affected file server.c.
3547 * Fixed a bug in silc_server_new_server. The SilcServer was
3548 set as the new server's context instead of SilcServerEntry.
3549 This naturally caused some weird bugs.
3551 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Do not delete the channel rekey task when adding it
3554 for in silc_server_create_channel_key.
3556 * Changed the silc_server_create_channel_key to return
3557 TRUE or FALSE to indicate the success of the channel key
3560 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Fixed MSVC++ project files and added missing files to
3563 Makefiles under win32/.
3565 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Do not add TCP_NODELAY flag if the operating system
3568 does not have it defined. Affected files are
3569 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3571 * Fixed buffer overflow from Irssi SILC Client. Affected
3572 file irssi/src/fe-common/core/themes.c.
3574 * Fixed double free in client library in the file
3575 lib/silcclient/client.c when disconnecting from server.
3577 * Applied double free patch from cras to Irssi SILC client.
3578 Affected files irssi/src/core/[modules/expandos].c
3580 * Fixed the disconnection handling to Irssi SILC Client.
3581 The application must call silc_client_close_connection
3582 in ops->connect client operation in case of failure of
3583 the connection. Affected file is
3584 irssi/src/silc/core/client_ops.c.
3586 * Do not set sock->protocol to NULL in the function
3587 silc_client_close_connection after executing the protocol's
3588 final callback since the sock might not be valid anymore.
3589 Affected file lib/silcclient/client.c.
3591 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * Do not enable SILC_THREADS if the linking with libpthread
3594 did not happen. Affected file configure.in.pre.
3596 * Added notion to protocol specification that server must
3597 verify the sent authentication payload with CMODE when
3598 setting the channel founder key. Implemented it to the
3599 server. Affected file silcd/command.c.
3601 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Added _EXTRA_DIST SILC distribution variable to the
3604 distributions file. It is used to conditionally add extra
3605 files or directories to the specific distribution. Affected
3606 files ./prepare, Makefile.am.pre and distributions.
3608 Removed the `_' from the start of the distribution names.
3611 * Added README.WIN32 for instructions to compile the Toolkit
3614 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3616 * Fixed a double free in disconnection in the server. Affected
3617 file is silcd/server.c.
3619 * Fixed the lib/silcske/groups.c to work now also with GMP
3620 MP library. The string conversion did not work when using
3621 specific base and the base is indicated in the string as well.
3623 * Created win32/ directory which now includes MSVC++ specific
3624 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3625 It will appear only in the toolkit distribution
3627 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Changed the key material distribution function in case when
3630 the hash output is too short. The data is now concatenated
3631 a bit differently than it used to. Made the change to the
3632 SKE protocol specification.
3634 * Added better GMP detection to configure.in.pre. A patch
3637 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Fixed a minor bug in SKE that might cause some problem on
3640 some platforms. Affected file lib/silcske/silcske.c.
3642 * Added the cookie checking for initiator in the SKE. It checks
3643 that the responder returns the sent cookie unmodified. The
3644 affected file is lib/silcske/silcske.c. Added new SKE
3645 error type INVALID_COOKIE that can be sent during the
3646 negotiation. Fixed some memory leaks as well.
3648 * Added the "invalid cookie" error message to Irssi SILC client's
3651 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3653 * Added `task_max' field to the SilcClientParams to indicate
3654 the maximum tasks the scheduler can handle. If set to zero,
3655 default values are used. Affected file lib/silcclient/silcapi.h.
3657 * Fixed memory leaks in silc_client_close_connection. Affected
3658 file lib/silcclient/client.c.
3660 * Added silc_client_del_client_entry to client library to free
3661 all memory of given client entry. Affected file is
3662 lib/silcclient/idlist.[ch].
3664 * Added new functions silc_client_del_channel and
3665 silc_client_del_server to delete channel and server entries.
3666 Affected file lib/silcclient/[silcapi.h/idlist.c].
3668 * Removed silc_client_del_client_by_id from silcapi.h.
3670 * Fixed the INFO command to return the server's own info
3671 correctly when querying by Server ID. Affected file is
3674 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3676 * Removed the non-blocking settings in WIN32 code in the
3677 silc_sock_[read/write] and added SleepEx instead. Affected
3678 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3679 of input data is now checked with FIONREAD and ioctlsocket.
3681 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Call silc_schedule_task_del_by_context in the
3684 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3685 Affected file lib/silccore/silcprotocol.c.
3687 * Call silc_protocol_cancel for active protocols in the
3688 silc_server_close_connection if the funtion
3689 silc_server_free_sock_user_data has not been called.
3690 Affected file silcd/server.c.
3692 * Generic tasks cannot be deleted using the del_by_fd
3693 task deleting function since generic tasks does not match
3694 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3696 * Added a notion to SILCOPER help file that the SILCOPER works
3697 only on router server, not on normal server.
3699 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Added for WIN32 support for the new scheduler as well.
3702 Affected file lib/silcutil/win32/silcwin32schedule.c.
3704 * Fixed the SHA1 implementation to work on various platforms.
3706 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3708 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3709 API. It is part of the scheduler now. Everything else is
3710 as previously but some functions has changed their names.
3711 Checkout the lib/silcutil/silcschedule.h for the interface.
3712 Updated all applications to use the new interface. Affected
3713 files are lib/silcutil/silcschedule.[ch].
3715 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Found a bug in the SKE implementation. The HASH value,
3718 specified by the protocol, was not computed correctly. The
3719 public key of the responder was not added to the computation
3720 even though it is mandatory. Affected file lib/silcske/silcske.c.
3721 This unfortunately causes incompatibilities with older
3722 clients and servers.
3724 * Added WIN32 specific network init and uninit functions:
3725 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3726 the Winsock2. Affected file lib/silcutil/silcnet.h and
3727 lib/silcutil/win32/silcwin32net.c.
3729 * Set the socket always to nonblocking mode on WIN32 after
3730 reading data or writing data. Affected file is
3731 lib/silcutil/win32/silcwin32sockconn.c.
3733 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3735 * Fixed various compilation problems under WIN32. Affected
3736 files lib/silcutil/win32/silcwin32thread.c and
3737 lib/silcutil/win32/silcwin32schedule.c.
3739 * Removed all _internal.h #includes from public header
3740 files. Internal headers must never be included from
3743 Removed also the lib/silcske/payload_internal.h file.
3745 * All include files that may be needed (public and some others
3746 included by the public headers) by application developers are
3747 now copied to the ./includes directory. It does not copy any
3748 internal headers. Affected file Makefile.defines.pre and all
3749 Makefile.am's under lib/ and subdirs.
3751 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3753 * Do not change the ~/.silc directory's permissions automatically.
3754 Affected file irssi/src/silc/core/clientutil.c.
3756 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3758 * Do not cancel the protocol in silc_server_close_connection
3759 it might cause recursion. Now cancelled in the function
3760 silc_server_free_sock_user_data. Affected file silcd/server.c.
3762 * Fixed the silc_server_remove_clients_by_server to regenerate
3763 the channel keys correctly finally. Added also new function
3764 silc_server_remove_clients_channels to actually do it.
3765 Affected file silcd/server.c.
3767 * Fixed the silc_server_new_channel to not crash by giving
3768 wrong router to the new channel. Affected file is
3769 silcd/packet_receive.c.
3771 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3773 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3774 which is given as argument to the silc_client_alloc now.
3775 It can be used to configure the client and set various parameters
3776 that affect the function of the client.
3778 * The USERS command in server did not check whether the channel
3779 is private or secret. Affected file silcd/command.c.
3781 * Added new argument to the USERS command in protocol specification.
3782 The USERS command now can take the channel name as argument
3783 as well. Added support for this in client and server and
3784 updated the protocol specs.
3786 * Completed the GETKEY command in client. It can be now used
3787 to fetch also servers public key not only some clients.
3788 Affected files lib/silcclient/command[_reply].c.
3790 * Added silc_client_get_server to return server entry by the
3791 server name. Affected files lib/silcclient/silcapi.h and
3794 * Redefined the IDENTIFY command in protocol specification to be
3795 more generic. It now can be used to query information about
3796 any entity in the SILC Network, including clients, servers and
3797 channels. The query may be based either the entity's name
3798 or the ID. Added support for this in both client and server.
3800 Affected files silcd/command.c and lib/silcclient/command.c
3801 and command_reply.c.
3803 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3804 the _from_client and _from_server functions. Affected file
3807 * Added silc_client_get_channel_by_id_resolve to the file
3808 lib/silcclient/silcapi.h to resolve channel information by
3809 its ID. Added also silc_client_get_channel_by_id that
3810 does not resolve it from the server.
3812 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Added SilcServerEntry context into the client library
3815 to represent one server. The INFO command now allocates
3816 these to save the resolved server info. For now on the
3817 client library will also keep information about servers,
3818 connected and resolved with INFO.
3820 The INFO command now allocates the SilcServerEntry context
3821 and saves the server info there. The COMMAND_REPLY in
3822 the INFO now returns the parameters to application in
3823 same order as defined in the protocol specification.
3825 The entries are cached in the client->server_cache.
3827 * The INFO command is now issued after received the Client ID
3828 from the server. Affected file lib/silcclient/client.c.
3830 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3831 to the application as the mode changer might be server.
3832 It is guaranteed that NULL is not returned anymore to the
3833 application. Affected file lib/silcclient/client_notify.c.
3835 The ID Type is now also passed to the application so that
3836 it can check whether the returned entry is SilcClientEntry
3839 Added new function silc_client_get_server_by_id to return
3840 the server entry by ID. Affected files are the
3841 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3843 * Do not create the channel in the Irssi SILC Client when issuing
3844 the JOIN command but when received the sucessful JOIN command
3845 reply. Otherwise the channel might get created even though we
3846 could not join it. The Affected file is
3847 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3849 * Fixed a channel joining bug in router. The router must also
3850 check the channel modes, invite and ban lists etc. when serving
3851 the JOIN command sent by normal server. Affected file is
3852 silcd/command.c. The router now resolves the client's
3853 information from the server who sent the JOIN command if it
3854 does not know it, and processes the JOIN command only after
3857 * Changed the SilcCommandCb to take new argument; void *context2.
3858 Affected file lib/silccore/silccommand.h
3860 The second argument in the command callbacks in the server now
3861 includes the SilcServerCommandReplyContext if the command was
3862 called as pending command callback from the command reply.
3863 Otherwise it is NULL. When called as pending the status of the
3864 command reply will be checked and if it was erronous the
3865 error will be sent to the original sender of the command.
3866 This way the client always receives the error messages even
3867 though the server was actually the one who received the error
3868 when it resent the command to router, for example. Affected
3869 files silcd/command[_reply].[ch].
3871 * Fixed sending WHOWAS command's error message to client if
3872 the requested client could not be found. It was missing.
3875 * Changed the CMODE and CUMODE commands reply arguments in the
3876 protocol specification. The Channel ID is now sent in both
3877 of the commands to identify the channel. Implemented this
3878 new feature to the client and server. Affected files
3879 lib/silcclient/command_reply.c and silcd/command.c.
3881 * Made better checks for invite and ban lists in the JOIN
3882 command in server. Affected file silcd/command.c.
3884 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3886 * The server now performs the incoming host IP/DNS lookup
3887 using the silc_socket_host_lookup and thus does not block
3888 the server anymore. Affected file silcd/server.c.
3890 * Completed the multi-thread support for SILC Scheduler in
3891 the lib/silcutil/silcschedule.c.
3893 * Fixed the configure.in.pre to detect the pthread correctly
3896 * Fixed a deadlock in silc_task_queue_wakeup in the file
3897 lib/silcutil/silctask.c.
3899 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Added new function silc_schedule_wakeup that is used in
3902 multi-threaded environment to wakeup the main thread's
3903 schduler. It needs to be used when a thread adds a new task
3904 or removes a task from task queues. After waking up, the
3905 scheduler will detect the task queue changes. If threads
3906 support is not compiled in this function has no effect.
3907 Implemented the wakeup mechanism to both Unix and WIN32
3908 systems. Affected files are lib/silcutil/silcschedule.[ch],
3909 lib/silcutil/unix/silcunixschedule.c and the
3910 lib/silcutil/win32/silcwin32schedule.c.
3912 * Added new function silc_task_queue_wakeup to wakeup the
3913 scheduler by the specified task queue. Affected file
3914 lib/silcutil/silctask.[ch].
3916 * The silc_socket_host_lookup_start now wakes up the scheduler
3917 after adding the timeout task. Affected file is
3918 lib/silcutil/silcsockconn.c.
3920 * The silc_socket_host_lookup is synchronous now if the threads
3921 support is not compiled in. However, the callback is still
3922 called asyncronously through the scheduler, anyway. Affected
3923 file lib/silcutil/silcsockconn.c.
3925 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Added new function silc_socket_host_lookup to perform
3928 asynchronous IP and FQDN lookups for the socket connection.
3929 Affected files lib/silcutil/silcsockconn.[ch].
3931 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3934 that may or may not compile the mutex support in.
3936 Changed the silc_mutex_alloc interface. It allocates the
3937 mutex now to the sent pointer and returns TRUE or FALSE.
3939 Affected file lib/silcutil/silcmutex.h.
3941 * Wrote the SILC Task Queue interface to support multi-threads.
3942 Affected file lib/silcutil/silctask.[ch].
3944 * Wrote the SILC Scheduler to support multi-threads. Affected
3945 file lib/silcutil/silcschedule.c.
3947 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3950 in lib/silcutil/win32/.
3952 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3954 * Defined SILC Mutex API and SILC Thread API and implemented
3955 them for Unix. Affected files are
3956 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3957 lib/silcutil/unix/silcunixmutex.c and
3958 lib/silcutil/unix/silcunixthread.c.
3960 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Fixed the silc_server_remove_clients_by_server's channel
3963 key re-generation. The hash table handling was incorrect
3964 and would not work with many channels. Affected file is
3967 * Fixed some memory leaks around the server code.
3969 * Rewrote the silc_server_get_users_on_channel to support IPv6
3970 based Client ID's. Affected file silcd/server.c.
3972 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3973 specification. However, a separate document must be written
3974 to define the detailed signing procedure and the payload
3975 associated with the flag. Defined the flag to the
3976 lib/silccore/silcchannel.h as well.
3978 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3980 * Changed the dynamic tables to static size tables in the
3981 lib/silccrypt/silchmac.c.
3983 * Removed GCC dependencies from the code. A patch by cras.
3985 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3987 * Do not show the error "Error receiving packet bla bla"
3988 in server if it really was not an error (-2 means that reading
3989 is pending). Affected file silcd/server.c.
3991 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3993 * Fixed a possible crash in silc_server_remove_clients_by_server
3994 in silcd/server.c. Fixed there also some memory leaks.
3996 * Fixed the silc_idlist_replace_client_id. It could replace
3997 wrong key in the hash table. Affected file silcd/idlist.c.
3999 * Do not check whether there are global users on the channel
4000 if the channel->global_users is FALSE. Affected functions
4001 silc_server_remove_from_one_channel and
4002 silc_server_remove_from_channels in silcd/server.c. Also,
4003 do not check if the removed client is local as we can be
4004 sure that global client was not removed from the channel
4005 and checking for global users is not needed.
4007 * The silc_server_remove_clients_by_server now re-generates
4008 the channel keys correctly for those channels that had
4009 clients removed from them. Affected file silcd/server.c.
4011 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Found the reason of random crashes in the server. We weren't
4014 ignoring the SIGPIPE signal (which can be sent in write())
4015 and it crashed the server. Affected file silcd/silcd.c.
4017 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Assure that sock->user_data is not NULL in the function
4020 silc_server_packet_send in silcd/packet_send.c.
4022 * Disconnect the remote connection if it could not be added
4023 to any ID lists in the server. The affected file is
4026 * Check in silc_server_packet_send[_real/dest] that the
4027 socket is not disconnecting and ignore the data if it is.
4028 Affected file silcd/packet_send.c.
4030 * Define inline to __inline on native WIN32 compilation.
4031 Affected file includes/silcwin32.h.
4033 * Added some explicit type casts for inline code since MSVC
4034 require them. Affected files lib/silcutil/silcbuffer.h,
4035 lib/trq/silcdlist.h and lib/trq/silclist.h.
4037 * Print warning in log files from now on if the packet
4038 decryption fails. Affected file silcd/server.c.
4040 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Changed the `say' client operation's interface to accept
4043 new `type' argument to indicate the type of the message sent
4044 by the library. The application may filter the library's
4045 messages according the type. The affected file is the
4046 lib/silcclient/silcapi.h.
4048 * Added two new functions to lib/silcclient/silcapi.h:
4049 silc_client_del_client and silc_client_del_client_by_id.
4050 Affected file lib/silcclient/idlist.c.
4052 * Moved the clientincludes.h from includes/ to silc/ and
4053 serverincludes.h from includes/ to silcd/.
4055 * The modes for the CMODE and CUMODE are now passed as
4056 uint32 for application with COMMAND_REPLY. The affected
4057 file is lib/silcclient/command_reply.c.
4059 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * /WHOIS without arguments shows client's own information.
4062 Affected file lib/silcclient/command.c.
4064 * Changed PING to not accept any arguments. The specs
4065 says that client can ping only the connected server so
4066 requiring an argument is not needed. Affected file is
4067 lib/silcclient/command.c.
4069 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4071 * Fixed a fatal bug in private message sending and reception
4072 encryption and decryption when using private message keys.
4073 The implementation was incorrect and did not follow the
4074 specification. It causd that some of the message were
4075 lost since it did not use the sending and receiving keys
4076 as the protocol suggests. This has been fixed and will cause
4077 incompatibilities with older clients when sending private
4078 message encrypted with private message keys. Affected files
4079 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4080 and various other in Irssi SILC Client.
4082 Added `responder' boolean argument to the functions
4083 silc_client_add_private_message_key[_ske] to indicate when
4084 the key is added as responder or initiator of the key
4087 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4089 * Removed the silc_ske_check_version function and created
4090 a SilcSKECheckVersion callback. Added also a function
4091 silc_ske_set_callbacks that is now used to set all SKE
4092 callbacks. The callback functions are not given to
4093 the SKE functions anymore, but this function is used to
4096 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4098 * Added `silc_version' argument to the silc_client_alloc
4099 to define the version of the application for the library.
4100 The library will use the version string to compare it
4101 against the remote host's (usually a server) version
4102 string. Affected file lib/silcclient/silcapi.h
4104 * Added the KE protocol context to Key Agreement context
4105 in client library so that we can abort the SKE if it
4106 is in process when we get timeout. Affected file is
4107 lib/silcclient/client_keyagr.c.
4109 * Do not resolve the client ID forever if it returns in the
4110 first time that such client does not exist. This was done
4111 for example with private message. Affected file is
4112 lib/silcclient/client_prvmsg.c.
4114 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4116 * Do not add regex.h for WIN32. The affected file
4117 includes/silcincludes.h.
4119 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4120 not work yet 100%. It generates the DLL's automatically
4121 when compiling with --with-win32 under cygwin.
4123 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4125 * lib/contrib/regex.c is not compiled on WIN32.
4127 * Added silc_net_get_socket_opt function to the
4128 lib/silcutil/silcnet.h.
4130 * Added includes/silcwin32.h for WIN32 specific includes
4133 * Do not use ptime structure or any of the posix process
4134 functions on WIN32 in lib/silccrypt/silrng.c.
4136 * Added silc_gettimeofday to provide generic function
4137 for struct timeval on all platforms. Added the function
4138 to lib/silcutil/silcutil.h.
4140 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4142 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4143 library as they clearly belong there. As a plus side we
4144 can make the actual socket connection routines platform
4147 Added also new generic function silc_socket_read and
4148 silc_socket_write (that used to be silc_packet_[read/write].
4149 The implementation of these are platform specific.
4151 * Added WIN32 specific routines of silc_socket_[read/write]
4152 to lib/silcutil/win32/silcwin32sockconn.c.
4154 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4156 * Added preliminary support for native WIN32 compilation under
4157 cygwin (using the -mno-cygwin option for GCC) to the
4158 ./configure.in.pre. The --with-win32 now prepares the
4159 compilation for native WIN32.
4161 * Rewrote the SILC Scheduler interface in the file
4162 lib/silcutil/silcschedule.h. The scheduler is now context
4163 based and does not have anymore any global static scheduler.
4164 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4165 and created lib/silcutil/win32 directory for WIN32 based
4168 * Added Unix specific network routines to the
4169 lib/silcutil/unix/silcunixnet.c and the old
4170 lib/silcutil/silcnet.c includes now only generic routines.
4172 Added WIN32 specific network routines to the
4173 lib/silcutil/win32/silcwin32net.c.
4175 * Added Unix specific utility functions from the
4176 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4178 * Added WIN32 SILC Scheduler to the file
4179 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4182 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4184 * Do not handle JOIN notify in the server if the target client
4185 is not registered (idata->registered == FALSE). The affected
4186 file is silcd/packet_receive.c.
4188 * Update the nickrec->founder in event_cumode in the Irssi SILC
4189 client. Affected file irssi/src/silc/core/silc-channels.c.
4191 * Fixed the CUMODE_CHANGE notify handling in the server when
4192 server and router are announcing their clients on channels.
4193 Now the mode changes are saved and notified correctly. The
4194 affected file is /silcd/packet_receive.c.
4196 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4197 They really did not replace the cache entry in the ID Cache.
4198 Now they do that. Affected file silcd/idlist.c.
4200 * Fixed the KICK notify handling in the Irssi SILC client to
4201 update the channel records so that the kicked client does not
4202 appear to be on the channel. The affected file is
4203 irssi/src/silc/core/silc-channels.c.
4205 * Always update the conn->current_channel when executing command
4206 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4208 * Fixed the KILL notify handling in Irssi SILC client to remove
4209 the killed client on all channels.
4211 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4213 * Fixed the silc_parse_command_line to remove extra spaces
4214 from the start and end of the arguments. Affected file is
4215 lib/silcutil/silcutil.c.
4217 * Cancel and free any active protocol in the function
4218 silc_server_close_connection. Affected file silcd/server.c.
4220 * Cancel and free any active protocol in the function
4221 silc_client_close_connction. Affected file is
4222 lib/silcclient/client.c.
4224 * Do not execute the KILL command for clients that are in
4225 history (ie. they are not in the network). Affected file is
4228 * Fixed KILL notify handling, client does not crash anymore.
4229 Affected file irssi/src/silc/core/silc-channels.c.
4231 * Reduced the default packet buffer size from 2048 to 1024 in
4232 lib/silccore/silcpacket.c.
4234 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4235 counter to the SKE context that is incresed when the SKE library
4236 performs async operation outside the library. If the outside
4237 process frees the SKE context and FREED status will be set
4238 and the library will detect after the sync operation that the
4239 libary is freed. The affected files are
4240 lib/silcske/silcske[_status].[ch].
4242 * Resolve the client entry information in the function
4243 silc_client_channel_message to assure that NULL pointer is not
4244 passed as client entry to the application. */
4246 * Fixed the task timeout calculation to assure that there is
4247 never negative timeouts. The affected file is
4248 lib/silcutil/silcschedule.c.
4250 * Fixed the channel user mode notification sending in server.
4251 It was sent point-to-point to the router (or to server by router)
4252 but it needs to be destined to a channel. The routines now
4253 supports sending the channel user mode notifys to the channels
4254 when announcing clients and channels. Affected files are
4255 silcd/server.c and silcd/packet_receive.c.
4257 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4258 It did not actually replace the old channel entry in the cache.
4259 Affected file lib/silcclient/client_notify.c.
4261 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Fixed a possible crash in silc_packet_send_prepare. It now
4264 assures always that there is enough space in the buffer and
4265 at the tail area of the buffer (for MAC).
4267 Fixed the inbound buffer reallocation in silc_packet_read.
4268 It was old code and did not handle the reallocation correctly.
4271 The affected file is lib/silccore/silcpacket.c.
4273 * Fixed buffer overflow in silc_parse_nickname in the file
4274 lib/silcutil/silcutil.c.
4276 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * make install generates new server keys only if there is not
4281 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4284 Added check that if the NOREPLY is set then we will not send
4285 the away message. This avoids infinite loop of away messages
4286 if both clients are away. The affected file is
4287 lib/silcclient/client_prvmsg.c.
4289 * Fixed client crash if /NICK was given without arguments.
4290 Affected file lib/silcclient/command.c.
4292 * Server does not send the invite list in INVITE command back
4293 to the client if the list was not altered. Added this notion
4294 to the protocol spec as well. Affected file silcd/command.c.
4296 Fixed possible crash in INVITE command by checking the
4297 value of silc_server_get_client_route command.
4299 * Fixed the INVITE notify type handling. The arguments are now
4300 taken in correct order and client does not crash. The affected
4301 file is irssi/src/silc/core/silc-channels.c.
4303 Removed the "Inviting xxx to channel" message from the
4304 client library away and let the application handle it.
4305 Affected file lib/silcclient/command.c. Added that message
4306 to Irssi SILC client's message formats.
4308 * Fixed CMODE command crash in client. It now checks the
4309 amount of arguments correctly and does not crash. The affected
4310 file is lib/silcclient/command.c.
4312 * Do not create new channel automatically in silc_channels_join
4313 but check whether the channel by that name already exists.
4314 Affected file irssi/silc/core/silc-channels.c.
4316 * Do not send the SERVER_SIGNOFF to router if the disconnected
4317 entity was the router. Affected file silcd/server.c.
4319 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4320 SILC client as it was missing from there.
4322 Added the handling of the KICK notify to the Irssi SILC client
4323 as it was missing. Added "you have been kicked" message to
4324 Irssi SILC client's message modules formats.
4326 Added the handing of the KILL notify to the Irssi SILC client
4327 as it was missing. Added the kill message module formats
4330 The affected file is irssi/src/silc/core/silc-channels.c.
4332 * The router did not save the channel mode the server announced.
4333 Affected file silcd/packet_receive.c.
4335 * Fixed a possible crash in INFO command in server. If the
4336 server did not provide the server info it crashed. Affected
4337 file silcd/command.c.
4339 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Fixed the GETKEY command in the server to check also the
4342 global list. Otherwise the GETKEY would not work correctly
4343 in normal SILC server. Affected file silcd/command.c.
4345 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4347 * Fixed GETKEY crash, it crashed if the command did not succseed.
4349 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4352 is now real and not just an macro interface to GMP.
4354 Removed the entire GMP from the source tree and imported new
4355 NSS MPI library instead. Reason for removing GMP is that it is
4356 extremely large and compiles extremely slow. The NSS MPI
4357 is only a few files and compiles in less than 10 seconds.
4358 The speed is also about the same as GMP. The MPI is imported
4359 to lib/silcmath/mpi.
4361 If the system has GMP installed we will still use the GMP.
4362 If it is not then the NSS MPI will be compiled.
4364 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Merged a long nickname (127 characters long) crash bugfix from
4367 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4369 * Merged a freed memory reference bugfix from Irssi CVS tree.
4370 Affected file irssi/src/core/commands.c.
4372 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Added the server's public key sving and verification to the
4375 server when performing the SKE. This was missing and the
4376 remote server's (or router's) public key was accepted without
4377 checking whether we have it previously or trust it at all.
4378 Affected file silcd/protocol.c.
4380 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4382 * Check in the silc_server_timeout_remote if protocol is active
4383 and make sure that the protocol's final callback is called so
4384 that all memory if freed. Affected file silcd/server.c.
4386 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * silc_server_whois_send_reply crashed the server if the nickname
4389 was 127 characters long. Affected file silcd/command.c.
4391 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Added sanity check to the silc_server_new_client. If the hostname
4394 is provided inside username then check that the provided hostname
4395 really is the same as the resolved one. If the hostname was not
4396 resolved then check it from the public key. Affected file is
4397 silcd/packet_receive.c.
4399 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4400 if the server disconnected us and the connection is not valid
4401 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4403 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4404 the library to the lib/silcutil/silcutil.[ch].
4406 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Close log file after open. Affected file
4409 lib/silcutil/silclog.c.
4411 * Check whether sock == NULL in silc_client_send_packet and return
4412 if it is. Affected file lib/silcclient/silcclient.c.
4414 * Check rec->entry == NULL in the Irssi SILC Client before
4415 sending the channel message. Affecte file is
4416 irssi/src/silc/core/silc-servers.c.
4418 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4420 * Merged a splitted window bugfix from Irssi CVS tree. The
4421 affected file is irssi/src/fe-text/textbuffer-view.c.
4423 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4424 It did not print nickname.
4426 * Improved the distributions system a bit.
4428 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4431 irssi/src/fe-text/gui-window.c.
4433 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4434 to in-active server. The affected file is
4435 irssi/src/silc/core/client_ops.c.
4437 * Resolve the client in USERS command reply if the entry does
4438 not have username resolved. The affected file is
4439 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4440 command to WHOIS command to really resolve stuff. The USERS
4441 is not used any more in any critical section so WHOIS can
4442 be used even though it might be slower than IDENTIFY.
4444 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4447 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Changed the protocol API a bit more consistent in the
4450 lib/silccore/silcprotocol.[ch].
4452 * Changed the following headers to ROBODoc format:
4454 lib/silccore/silcpayload.h
4455 lib/silccore/silcprotocol.h
4456 lib/silccore/silcsockconn.h
4458 All core library headers are now formatted.
4460 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Fixed a bug in Irssi SILC client; do not show that you are
4463 server/router operator if you really are not. Affected file is
4464 irssi/src/silc/core/client_ops.c.
4466 * Renamed silc_command_free_payload to silc_command_payload_free.
4467 Affected file lib/silccore/silccommand.h
4469 * Added silcmath.h to include the prototoypes of various routines
4470 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4473 * Changed the following headers to ROBODoc format:
4475 lib/silccore/silcchannel.h
4476 lib/silccore/silccommand.h
4477 lib/silccore/silcid.h
4478 lib/silccore/silcidcache.h
4479 lib/silccore/silcmode.h
4480 lib/silccore/silcnotify.h
4481 lib/silccore/silcpacket.h
4482 lib/silcmath/silcmath.h
4484 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Added checking to the server code not to start the server if
4487 ciphers and stuff are not configured properly. Affected files
4488 silcd/serverconfig.[h] and silcd/server.c.
4490 * Changed the layout of the header files of the public interfaces
4491 in the SILC libraries. The new layout supports ROBODoc
4492 documentation tool (and some others) so that it is easy to create
4493 a library reference manual. All the other headers and source
4494 code must still follow the CodingStyle document. Also source
4495 code must not include these ROBODoc stuffs, only the headers.
4496 Furthermore, all public interface headers must now be named
4497 by using `silc' prefix, example: silcapi.h, silccipher.h.
4498 Some files were renamed due to this. All the other headers
4499 must not be used as public interfaces. I will update the
4500 CodingStyle document later. Changed following headers, so far:
4502 lib/silcclient/silcapi.h
4503 lib/silccore/silcauth.h
4504 lib/silccore/silcprivate.h
4505 lib/silccrypt/silcdh.h
4507 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4511 * Removed silc_client_packet_send_flush from the client library
4512 as it is not needed. Affected file lib/silcclient/client.[ch].
4514 * Added printing of message of unresolved authentication method
4515 to the Irssi SILC client. Added it to the module formats.
4516 Removed the same message from the client library.
4518 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4520 * Added new distribution feature, DISTLABEL. Every distribution
4521 can define own preprocessor label that can be used in the
4522 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4523 file distributions, acconfig.h.pre and prepare.
4525 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Added Makefile.defines_int to include the actual definitions
4528 for Makefile.defines.in. Tested the new distribution system,
4529 created distributions and tested installation.
4531 * Added AWAY message printing to the Irssi SILC client. Added
4532 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4534 * Added SCONNECT command to call the SILC's CONNECT command.
4535 Cannot use CONNECT directly since Irssi uses that internally.
4536 Affected file irssi/src/silc/core/silc-servers.c.
4538 Added ACTION local command. It is same as ME command but takes
4539 the channel as mandatory argument.
4541 Rewrote some of the Irssi's help files to suite for SILC
4544 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Added Makefile.defines[.in] that should for now on be included
4547 in all Makefile.am file in the source tree. That file includes
4548 all common compilation definitions for SILC source tree.
4550 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Minor changes to the ./prepare script to change the package
4553 name according the distribution name to the configure.in.
4555 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Created new distribution system. Added file `distributions'
4558 that defines all the distributions that can be created out of
4559 the SILC source tree. The ./prepare script now reads that
4560 file to determine how to prepare the distributions. The
4561 first argument to the ./prepare is the name of the distribution
4562 and second is the version of the distribution. If given
4563 without arguments it creates the default (toolkit) distribution
4564 with the default version (defined in ./prepare).
4566 All Makefile.am files that are subject to the distributions
4567 are now named as Makefile.am.pre. These are ./Makefile.am
4568 and lib/Makefile.am. Others may be changed later.
4570 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Added invite list, ban list, some key management and connection
4573 error message printing to module formats in the Irssi SILC client.
4575 * Added new silc_client_set_away_message to set the away message
4576 that is back to the person who sent private message. The
4577 affected file lib/silcclient/silcapi.h and the
4578 lib/silcclient/client_prvmsg.c.
4580 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Fixed the private message sending in the Irssi SILC client,
4583 added local command KEY to the Irssi SILC client.
4585 Added key management and key agreement message formats to the
4586 irssi/src/fe-common/silc/module-formats.[ch].
4588 Added USERS (alias WHO) printing, server/router operator
4589 indication and LIST command printing to the module formats.
4591 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Fixed channel joining notify handling, cumode notify handling
4594 from Irssi SILC client.
4596 * Added SILC specific module-formats to the Irssi SILC client so
4597 that SILC specific message hilighting, colors etc is possible.
4598 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4600 Added channel mode, channel user mode, actions, notices,
4601 whois and whowas printing to the the module-formats.c.
4603 * Fixed a bug in channel deletion in the server. The channel
4604 is not left to the cache even if the channel founder auth mode
4605 is set when there are no users anymore on the channel. Affected
4606 file silcd/server.c.
4608 * The silc_net_localhost now resolves the entire hostname including
4609 the domain name. Affected file lib/silcutil/silcnet.c.
4611 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Changed the ask_passphrase client operation to be ascynchronous.
4614 It has now a completion callback and a context that the
4615 application must call after it has got the passphrase from
4616 the user. Affected files lib/silcclient/silcapi.h,
4617 lib/silcclient/protocol.c, lib/silcclient/command.c and
4620 Added SilcAskPassphrase callback that the application calls
4621 to deliver the passphrase to the library.
4623 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4624 The public key verification and especially a certificate
4625 verification is asynchronous procedure.
4627 Added new SILC_SKE_STATUS_PENDING status to indicate the
4628 request is pending and a callback will be called to finalize
4631 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4632 indicate that remote end did not send its public key (or
4633 certificate), even though we require it. Added check for this
4634 condition in the SKE. This was a security bug, now fixed.
4636 Defined new SilcSKEVerifyCbCompletion callback that is called
4637 when the verification process is completed.
4639 The affected files lib/silcske/silcske_status.h and
4640 lib/silcske/silcske.[ch].
4642 * Changed the verify_public_key client operation to be async
4643 as well. Defined SilcVerifyPublicKey callback that is used to
4644 indicate the success of the public key verification process.
4646 Changed the server and client to use the new async client
4649 * Changed the Irssi SILC client's internal scheduler to be called
4650 twice as many times as it used to be. As a result the client
4651 should be a bit faster now. Affected file is
4652 irssi/src/silc/core/silc-core.c.
4654 * Added support to Irssi SILC client of asynchronous public key
4655 verification and passphrase inquiry. Affected file is
4656 irssi/src/silc/core/silc-core.c.
4658 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Do not say "You have left channel %s" in client library.
4661 Moved it to the application. Affected files are
4662 lib/silcclient/command.c and silc/client_ops.c.
4664 * Fixed silc_client_get_clients. Command context was not
4665 duplicated and was freed memory in the callback. Affected
4666 file lib/silcclient/idlist.c.
4668 * Do not say "you are now talking..." on JOIN command in the
4669 client library. The appliation must handle it.
4671 * Do not say ".. changed topic to" in command reply in the
4672 client libary. The application must handle it.
4674 * Fixed TOPIC command sending in the client library.
4676 * Fixed a memory leak in silc_client_command_free in the file
4677 lib/silcclient/command.c.
4679 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Imported a modified version of Irssi client to the source tree.
4682 The Irssi will be used to create a new client called
4683 Irssi SILC. Imported to irssi/.
4685 Added silc_core_init_finish function to the Irssi. Affected
4686 file irssi/configure.in.
4688 A lot changes in the Makefile.ams around the irssi tree.
4690 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Do not rehash if the new size is same as the old size of the
4693 hash table, in the silc_hash_table_rehash*. The affected file
4694 lib/silcutil/silchashtable.c.
4696 * Replaced hash_table_del_by_context calls from the server
4697 (when channel->user_list and client->channels) to the
4698 hash_table_del as it is sufficient and faster.
4700 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Added silc_hash_table_list, silc_hash_table_get and the
4703 SilcHashTableList structure to provide an alternative way to
4704 traverse the hash table. The affected files are
4705 lib/silcutil/silchashtable.[ch].
4707 * Changed the server's idlist routines to use the hash table
4708 routines to optimize the code.
4710 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Replaced the client entry's `channel' list and channel entry's
4713 `user_list' list to hash tables for optimized lookup. Changed
4714 the code to use the hash table interface around the code.
4715 Affected file lib/silcd/idlist.[ch].
4717 * Added `auto_rehash' boolean argument to the function
4718 silc_hash_table_alloc to indicate whether the hash table should
4719 auto-rehash when it thinks is appropriate time. It will
4720 increase the hash table size if the there is twice as much
4721 entries in the table than the size of the table, and will
4722 decrease the size if there are twice as less entries than
4723 the size of the table.
4725 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4729 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * silc_idcache_purge_by_context deletes the entry now by context
4732 as it is supposed to do. Affected file lib/silccore/idcache.c.
4734 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4735 client is not anymore valid (WHOWAS givens the info) and not
4736 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4738 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Removed the `data' and `data_len' arguments from the ID Cache
4741 interfaces and added `name' argument. ID Cache does not handle
4742 anymore the binary data only a names associated with given ID.
4744 * When hashing a Client ID with silc_hash_id the entire ID is
4745 not hashed anymore, instead only the hash of the Client ID is
4746 hashed. This way we can access the Client ID from the cache
4747 with Client ID but with the hash of the ID (which is a hash of
4748 the nickname) as well without any difference in performance.
4750 Added also silc_idcache_find_by_id_one_ext to do one on one
4751 searching when we have the actual ID. Added also function
4752 silc_hash_client_id_compare. The affected files are
4753 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4755 * When hashing the name associated with a ID it is always done
4756 in lowercase. This way we can access the cache without worrying
4757 about case-sensitivity, even though, for example nicknames are
4760 * Fixed a bug in server with channel message sending. It put
4761 wrong ID type as destination ID. The affected file
4762 silcd/packet_send.c.
4764 * silc_idcache_del_by_context now deletes from all hash tables
4765 by context. Affected file lib/silccore/idcache.c.
4767 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Changed the client library to use the new ID Cache interface.
4770 Changes around the source tree.
4772 * Added silc_hash_table_rehash_ext to rehash with specific
4773 hash function. Affected file lib/silcutil/silchashtable.[ch].
4775 * Added silc_hash_string_compare to compare two strings in the
4776 hash table. Affected file lib/silcutil/silcutil.[ch].
4778 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Added new function silc_idcache_del_by_context into the
4781 lib/silccore/idcache.[ch].
4783 * Changed the server's ID list routines to use the new ID Cache
4784 interface. Changes around the source tree.
4786 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Added silc_hash_table_del[_by_context]_ext functions in to the
4789 lib/silcutil/silchashtable.[ch].
4791 Removed silc_hash_table_find_all* routines and added new
4792 silc_hash_table_find_foreach to replace them.
4794 Added silc_hash_table_replace_ext function as extended
4795 replacing function. Separated the simple hash table interface
4796 from the extended hash table interface in the file
4797 lib/silcutil/silchashtable.h.
4799 * Fixed minor bugs and changed it to use some of the new
4800 hash table functions in lib/silccore/idcache.c
4802 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Added new function silc_hash_table_find_all to return all keys
4805 in the hash table by the specified key. As the hash table is
4806 collision resistant it also makes it possible to have several
4807 duplicate keys in the hash table. This function may be used to
4808 find all of the keys from the hash.
4810 Added user_context arguments to the SilcHashFunction,
4811 SilcHashCompare and SilcHashDestructor to deliver user specified
4814 Added new fuctions silc_hash_table_find[_all]_ext to do
4815 extended lookup with specified hash and compare functions and
4816 specified user contexts.
4818 Added new function silc_hash_table_add_ext to add the key
4819 with specified hash function and user context.
4821 Added new function silc_hash_table_foreach to traverse all
4822 entrys in the hash table. Added SilcHashForeach callback
4825 Added new function silc_hash_table_del_by_context to delete
4826 the entry only if the context associated with the key matches.
4828 Affected files are lib/silcutil/silchashtable.[ch].
4830 * Removed silc_hash_[server/client/channel]_id and added just
4831 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4832 silc_hash_id_compare to compare two ID's using as the hash table
4833 comparison function. Added also silc_hash_data to hash
4834 binary data and silc_hash_data_compare to compare it.
4836 * Removed silc_idlist_find_client_by_hash as it is not needed
4837 anymore. Affected file silcd/idlist.[ch].
4839 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4840 to use internally the SilcHashTable. The new ID Cache is a lot
4841 faster than the old one. Some of the ID Cache interface was also
4842 rewritten and obsolete and stupid functions were removed.
4844 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added entry_count field to the SilcHashTable to keep the number
4847 of the entries in the table. Implemented the function
4848 silc_hash_table_rehash. Added new function
4849 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4851 Fixed a minor bug in silc_hash_table_free.
4853 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4854 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4855 into the lib/silcutil/silcutil.[ch].
4857 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4859 * Implemented a collision resistant hash table into the
4860 lib/silcutil/silchashtable[ch]. See the header and the source
4861 for the SilcHashTable API.
4863 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4865 * Merged dotconf version 1.0.2 into lib/dotconf.
4867 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Do not compile anything in lib/silcsim/* if the SIM support
4870 is not enabled. The tree should now compile without problems
4873 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Compiled the SILC under cygwin. Compiled and tested briefly
4876 without problems. More tests needed. The SIMs didn't compile
4879 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4881 * Fixed possible crash in silc_get_username in the
4882 lib/silcutil/silcutil.c.
4884 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Fixed a va_arg in silc/client_ops.c.
4888 * Oops, RC5 routines were named AES and caused some problems
4889 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4891 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Added new SilcIDIP structure into the lib/silccore/id.h and
4894 replaced the old `ip' fields from all SILC ID's to that type.
4895 This is a step towards IPv6 support.
4897 The silc_id_get_len takes now the ID as an extra argument.
4898 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4899 both IPv4 and IPv6 based ID's.
4901 The affected files are lib/silccore/id.[ch] and other files
4902 around the tree using these routines.
4904 * Removed the ID length arguments in server from various
4905 silc_server_send_notify_* routines -> they are not needed
4908 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4910 * Fixed memory leak in silc_encode_pem_file in the file
4911 lib/silcutil/silcutil.c.
4913 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4915 * Check minor version as well in the SKE. Affected files are
4916 silcd/protocol.c and lib/silcclient/protocol.c.
4918 * Added --identifier option to the server so that an identifier
4919 can be when creating the public key for the server. Affected
4920 file is silcd/silcd.c.
4922 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4923 lib/silccrypt/silcpkcs.c.
4925 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4927 * Register default ciphers and stuff when using -C option with
4928 the server. Affected file sildc/silcd.c.
4930 * Put back the servers public key filename format, it is better
4931 than the new one. For now, the client keys are saved with the
4932 new filename format. The affected file silc/client_ops.c.
4934 * Implemented the Cipher API for the rest of the ciphers that
4935 did not implement it or implemented it the wrong way.
4937 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Register default ciphers and stuff when using the -S option
4940 in the client. Affected file silc/silc.c. Same also when
4941 creating new key pair with -C option.
4943 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Fixed the silc_verify_public_key client operation function to
4946 save the public keys differently. The fingerprint is now
4947 used as filename and not the hostname. This way also the
4948 client keys are saved uniquely and not with hostnames. The
4949 affected file is silc/client_ops.c.
4951 * Trimmed the silc_hash_fingerprint function to remove extra
4952 whitespaces from the end of the fingerprint. The affected
4953 file is lib/silccrypt/silchash.c.
4957 * Added silc_cipher_register_default function to register all
4958 default ciphers. It can be used when configuration files
4959 does not exist and the application does not want any specific
4960 ciphers in any specific order.
4962 The SilcDList is now used as silc_cipher_list dynamically
4963 allocated cipher list. Removed the static list all together
4964 and now all ciphers must be allocated to the dynamic list.
4965 The silc_cipher_alloc routine was changed to check only the
4968 All silc_cipher_* routines that used to return int returns
4971 The affected files lib/silccrypt/silccrypt.[ch].
4973 * The same thing was done to silc_hash_* as for silc_cipher_*
4974 routines. Affected files lib/silccrypt/silchash.[ch].
4976 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4977 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4978 Added also silc_pkcs_[un]register[_default] functions.
4979 Removed the data_context from the PKCS API.
4981 * Added silc_hmac_register_default function to register default
4982 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4983 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4984 to unregister all hmacs at once.
4986 * Register the default ciphers, hash functions, PKCSs and HMACs
4987 if client's configuration file does not exist. The affected
4990 * The client did not load the hash functions from the SIM
4991 modules at all. Added support for this. Affected file is
4992 silc/clientconfig.c.
4994 * When decoding public key with silc_pkcs_public_key_decode, check
4995 the supported algorithm only if PKCS are registered. Affected
4996 file lib/silccrypt/silcpkcs.c. The same was done with the
4997 silc_pkcs_private_key_decode.
4999 * Fixed the SILC List routines to keep the list always in order.
5000 It used to change the list's order when traversing the list but
5001 not it preserves the order. Affected file lib/trq/silclist.h.
5003 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Added the client library to use the SilcSocketConnection's
5006 reference counter (by silc_socket_dup) to prevent the bug that
5007 the socket object may be freed underneath async operation.
5009 * The name resolv library checking fixes in the configure.in.pre.
5012 * Created new version of the protocol drafts for future
5013 development. The -03 drafts are the ones that will be changed
5014 in the trunk now and the -02 will remain as they are.
5016 * Send list of CUMODE notifys to the router when announcing
5017 the channel users to the router. Affected file silcd/server.c.
5018 If the router receiving channel founder CUMODE for a channel
5019 that already has channel founder it will send CUMODE notify
5020 to the sender to remove the channel founder rights from the
5021 announced client. Affected file silcd/packet_receive.c.
5023 * The CUMODE notify may now use Server ID as well as the entity
5024 who changes the mode. Updated protocool specs.
5026 * Updated INSTALL and README files.
5028 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * New web pages in the http://silc.pspt.fi. The pages was
5035 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Implemented the [DenyConnectin] config section in the server.
5038 Added silc_server_config_denied_conn to check whether incoming
5039 connection is denied. Affected file silcd/serverconfig.[ch].
5041 * Do not check the ports when checking the incoming configuration
5042 data if the port is 0, meaning any. Affected file is
5043 silcd/serverconfig.c.
5045 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed buffer overflow in silc_string_compare in the file
5048 lib/silcutil/silcutil.c.
5050 * Fixed double free in silc_server_command_leave in the file
5053 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Fixed the version checking in the server. Affected file is
5058 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Fixed the configuration data fetching when accepting new
5061 connections in the server. Affected file silcd/server.c.
5063 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Added `sender_entry' argument to the function
5066 silc_server_packet_relay_to_channel so that we can check
5067 whether some destination actually belongs to the same route
5068 the sender belongs (ie, we must not resend the packet to the
5069 sender). Affected file silcd/packet_send.[ch].
5071 * Added `servername' field to the SilcClientEntry in the server
5072 to hold the name of the server where client is from. Affected
5073 file is silcd/idlist.h.
5075 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Moved the channel message encrypting in the router betwen
5078 router connections from silc_server_channel_message to the
5079 silc_server_packet_relay_to_channel since we want to check
5080 whether we have anybody channel before encrypting anything.
5081 Affected files silcd/packet_[receive/send].c.
5083 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * Fixed the [AdminConnection] server config section to support
5086 multiple entries. Affected file silcd/serverconfig.c.
5088 * Added support into the server to check the validity of the
5089 incoming connection before executing any KE or authentication
5092 * The connection configuration is now saved to the KE and
5093 connection auth protocol contexts and not fetched anymore in
5094 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5096 * The local hosts listenning address and port is also resolved
5097 now when starting the server. We want to have the socket object
5098 to include the real address and port for the listener. Added
5099 new function silc_net_check_local_by_sock into the files
5100 lib/silcutil/silcnet.[ch].
5102 * Fixed a broadcast bug in server -> do not broadcast if we
5105 * Fixed a routing bug. Do not route broadcast packets ever.
5106 Broadcast packets must be processed always and not routed since
5107 they may be destined to some other host than yourself and thus
5108 would get routed without no good reason. Affected file is
5111 * Added function silc_server_config_is_primary_route to check
5112 whether primary router connection has been configured (a router
5113 configuration that we are initiating). If there is not, we
5114 will assume that there is only two routers in the SILC network
5115 and we will use the incoming router connection as our primary
5116 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5118 * Changed the order of the broadcasting. Broadcast _after_ the
5119 packet has been processed not before. Affected file is
5122 * Fixed a [ClientConnection] parsing bug. The port was never
5123 parsed correctly thus resulting to port 0. Affected file
5124 silcd/serverconfig.c.
5126 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5127 argument and did not set the broadcast packet flag. Affected
5128 file silcd/packet_send.c. Fixed same bug in the function
5129 silc_server_send_notify as well.
5131 * If we receive NEW_ID packet for our own ID in the server, ignore
5134 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Removed the nickname from the Private Message Payload.
5139 Updated the code and the protocol specs.
5141 * Updated protocol specs for submitting to the IETF.
5143 * Tweaked the Random Number Generator a bit. Affected file
5144 lib/silccrypt/silcrng.c. Exported a new function
5145 silc_rng_[global]_add_noise which can be used to add more
5148 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Do not parse packets with different timeout when protocol
5151 is active -> may cause problem with rekey. Affected file
5154 * When server receives signoff notify it must not create
5155 new channel key if the client is on any channels since the
5156 sender of the signoff notify will create it.
5158 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Added printing of error messages during SKE protocol from the
5161 failure packet sent by server during SKE. Affected file
5164 * Removed the client's failure_callback handling with timeout
5165 and handle it immediately when received.
5167 * The SKE library returned wrong type in SUCCESS and FAILURE
5168 packets. They must be 32 bit MSB not 16 bit MSB.
5170 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Ok, rewrote the logic of the re-key and now it seems to work.
5173 I tested it on high traffic with frequent re-keys without
5174 problems. Added hmac_receive (and renamed hmac to hmac_send)
5175 in SilcClientConnection in lib/silcclient/client.h and
5176 in SilcIDListData in silcd/idlist.h. Also, removed the
5177 SilcPacketParserContext's cipher and hmac fields as they are
5178 not needed anymore and actually caused some problems when
5179 the ciphers and hmac's changed underneath the packet parser.
5181 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5183 * If re-key protocol is active then process the incoming packets
5184 synchronously since we must assure that icoming packets encrypted
5185 with the old key is processed before the new keys is set to
5186 use. This is true other packets than for REKEY packets.
5187 Affected file silcd/server.c. The same was done to client library
5188 as well, affected file lib/silcclient/client.c.
5190 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Fixed bug in client and server to accept the force send if
5193 the packet is send from silc_[server/client]_packet_process
5194 function. Otherwise the packets are never delivered, oops.
5196 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5198 * Disable force sending of packets when REKEY protocol is active.
5199 We must assure that no packet is sent directly when rekey is
5200 performed. All packets must be sent through packet queue.
5201 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5202 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5203 function is silc_[server/client]_packet_send_real to check
5206 * Replaced the SIM paths from example config files to
5207 /usr/local/modules. Also, make install creates now
5208 /usr/local/silc/logs directory to hold all the SILC server
5211 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5213 * Made the configure.in.pre work on Solaris. Patch by salo.
5215 * Made all ciphers compatible with non-x86 machines. Defined
5216 CBC mode macros into lib/silccrypt/ciphers_def.h.
5218 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5222 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * When MAC computation fails the silc_packet_decrypt returned 0
5225 even though it was supposed to return -1. Fixed this. The
5226 affected file is lib/silccore/silcpacket.c.
5228 * Do not replace the config files in /etc/silc (in make install)
5229 if they already exist. Affected file ./Makefile.am.
5231 * Do not send re-key packets immediately but through packet queue.
5232 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5234 * Changed silc_net_check_host_by_sock to return FALSE if the
5235 IP/DNS could not be resolved. Though, it returns the IP address
5236 now even if it could not resolve it (but returns also FALSE).
5237 Affected file lib/silcutil/silcnet.[ch].
5239 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Added silc_pkcs_decode_identifier to decode the public key's
5242 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5243 Added also silc_pkcs_free_identifier. Added also new context
5244 SilcPublicKeyIdentifier.
5246 * Added -S option to the silc client. It is used to dump the
5247 contents of the specified public key file.
5249 * Changed the PKCS api to return the public key length when
5250 setting the public key.
5252 * Fixed a fatal bug in the public and private key file loading.
5253 Affected file lib/silccrypt/silcpkcs.c.
5255 * Execute the packet parsing for client with zero (0) timeout
5256 if the protocol is active. Affected file silcd/server.c.
5258 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5260 * Made the key generation options to the silcd program. Added
5261 -C option, equivalent to client's option.
5263 * Added new [ServerKeys] config section to the server. It
5264 configures the server's public and private key.
5266 * Defined generic Public Key Payload into the protocol
5267 specification to send specific type of public keys and
5270 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5271 public key or certificate.
5273 * Implemented the GETKEY command to the server and to the
5274 client library and on user interface.
5276 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Made preliminary `make install' work.
5280 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Added SilcServerRekey context into silcd/idlist.h.
5284 * Added the PFS support as defined in the specification to the
5285 SKE protocol. Affected files lib/silcske/*.c.
5287 * Added `ske_group' field to the SilcServerRekey context to hold
5288 the number of the SKE group that is used with PFS in re-key.
5289 Affected file silcd/idlist.h.
5291 * Added PFS re-key support to the server. Affected file is
5294 * Added silc_protocol_cancel to cancel execution of the next
5295 state of the protocol. Affected file is
5296 lib/silccore/silcprotocol.[ch].
5298 * Added the re-key support with and without PFS to the client
5299 library. Re-key is performed once in an hour, by default.
5301 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5302 Added silc_client_rekey_callback and silc_client_rekey_final.
5303 Affected files are lib/silcclient/protocol.[ch] and
5304 lib/silcclient/client.[ch].
5306 * Removed the `hmac_key' and `hmac_key_len' fields from the
5307 SilcClientConnection structure; not needed. Affected file is
5308 lib/silcclient/client.h.
5312 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Do not ask whether user wants to use the negotiated private key
5315 for private messages, just use it. Affected file is
5316 silc/local_command.c.
5318 * Added `send_enc_key' and `enc_key_len' fields to the
5319 SilcIDListData structure since they are needed in the re-key
5320 phase. Affected file is silcd/idlist.[ch].
5322 * Implemented the simple re-key protocol into the server.
5323 Affected files silcd/server.c and silcd/protocol.[ch]. The
5324 re-key will be performed once in an hour, by default.
5326 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5327 Added silc_server_rekey, silc_server_rekey_callback and
5328 silc_server_rekey_final.
5330 * Removed Tunneled flag from the protocol. Updated the code
5331 and the specifications.
5333 * Adde `pfs' field to the SilcIDListData to indicate whether
5334 the PFS is to be performed in the re-key. Affected file is
5337 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5339 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5340 int64 of at least the xintXX size. If void * is less that 4
5341 bytes uint32 * will be used. Defined bool as boolean.
5343 * Changed _ALL_ unsigned long and unsigned int to uint32,
5344 unsgined short to uint16 in the source tree.
5346 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5347 not handle clients that has entry->data.registered == FALSE.
5348 They are not in the network anymore. Affected file is
5351 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * Implemented the sending of the SERVER_SIGNOFF notify in the
5354 server. Affected file is silcd/server.c.
5356 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5357 Added also silc_notify_payload_encode_args into the
5358 lib/silccore/silcnotify.[ch].
5360 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5361 Affected file silcd/packet_receive.c.
5363 * Implemented the SERVER_SIGNOFF notify handling in the client
5364 library. Affected file lib/silcclient/client_notify.c. Also,
5365 implemnted the printing of the SERVER_SIGNOFF info to the
5366 application. Affected file silc/client_ops.c.
5368 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5369 if the deleting was successful. Affected file silcd/idlist.[ch].
5371 * Added support for public key authentication in the connection
5372 authentication protocol in the client library. Affected file
5373 lib/silcclient/protocol.c.
5375 * Changed the server's silc_idlist_get_clients_by_* interface
5376 to support already allocated array so that new entries may be
5377 added to pre-allocated array. Affected file silcd/idlist.[ch].
5378 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5379 and command replies.
5381 * All command reply functions in the server now calls the
5382 pending command callback even if error occured. This way the
5383 error will be delivered to the client as well. Affected files
5384 silcd/command.c and silcd/command_reply.c.
5386 * Fixed INFO command to return local server's info if no server
5387 was provided. Affected file lib/silcclient/command.c.
5389 * Removed RESTART command for good. Updated the code and the
5392 * Rewrote parts of the task system. It is a bit simpler now.
5393 Removed unsued task priorities. The affected files are
5394 lib/silcutil/silctask.[ch].
5396 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Moved the USERS printing from the library to the application.
5399 Affected files lib/silcclient/command.c and silc/client_ops.c.
5401 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5405 * Added channel key re-key support. The re-key is perfomed
5406 only by the router and is done once in an hour. Added `rekey'
5407 field to the SilcChannelEntry in the server. Affected files
5408 silcd/server.c and silcd/idlist.h.
5410 * Added silc_task_unregister_by_context into the file
5411 lib/silcutil/silctask.[ch].
5413 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added SILC_UMODE_GONE mode to indicate when the client is not
5416 present in the SILC network. Added also support to the local
5417 command AWAY that will set this mode. Added support of showing
5418 "xxx is gone" in WHOIS command. The USERS command shows the
5419 gone status as well.
5421 * Fixed setting server and router operator privileges in the
5422 server's UMODE command. Affected file silcd/command.c.
5424 * Merged the SKE KE1 and KE2 payloads into one payload. The
5425 new KE payload is equivalent to the old KE2 payload.
5427 Cleaned up the SKE Start Payload parsing. It now uses the
5428 simple buffer unformatting to do the parsing. A lot faster
5431 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5432 to the SKE that is used to indicate whether both of the SKE
5433 parties should perform authentication. By default only the
5434 responder performs authentication. By setting this flag also
5435 the initiator must do authentication. By default it is unset
5436 since in normal SKE case, client to server connection, only
5437 the responder should do authentication. When doing SKE between
5438 two clients both should perform authentication. Updated the
5439 code and the protocol specs.
5441 * A little fix to IDENTIFY command in the server. Search the
5442 client first by hash not nickname. Affected file is
5445 * Fixed the silc_client_close_connection to support closing
5446 the client to client connections wihtout deleting too much
5447 data. Affected file lib/silcclient/client.c.
5449 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5450 are received if protocol used to be active but is not anymore
5451 the application would crash due to NULL pointer dereference.
5452 Affected files silcd/server.c and lib/silcclient/client.c.
5454 * Added `hash' field to the SilcClientConnection to include
5455 the hash function negotiated in the SKE protocol.
5457 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5458 to set the channel founder authentication data. A client can
5459 claim the founder rights later by providing the authentication
5460 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5461 This way the channel founder can regain the channel founder
5462 privileges even it is left the channel. This works only on
5463 local server and the client must be connected to the same
5464 server to be able to regain the founder rights. Updated the
5465 protocol specs accordingly.
5467 Added support to the CMODE command in the client to set the
5468 founder auth data. Read the README to see how to set it.
5470 Added support to the CUMODE command to claim the founder
5471 rights. Read the README to see how to do it.
5473 Added support for the founder authentication to the Channel
5474 Entry in the server. Affected file silcd/idlist.h.
5476 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5477 server's CMODE command. Affected file silcd/command.c.
5479 * Added the following new functions into lib/silccore/silcauth.[ch]:
5480 silc_auth_get_method and silc_auth_get_data.
5482 * The server now saves the remote hosts public key to the
5483 SilcIDListData pointer. Affected file silcd/protocol.c.
5485 * The normal server now does not remove the channel entry from
5486 the cache if the founder authentication data is set. It used
5487 to remove it if the founder was the last one on the channel on
5488 the server and left the channel. The auth data is saved and
5489 if the channel is re-joined later the old entry is used with
5490 the old auth data. Affected files silcd/command_reply.c and
5493 * Removed the `pkcs' field from the SilcIDListData structure
5494 in the server; it is not used. Affected file silcd/idlist.h.
5496 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed packet processing on slow links. Partial packets were
5499 never re-processed because the incoming data buffer was cleared
5500 by the application. Application must not directly clear the
5501 sock->inbuf, the packet processing routines handle it. Fixed
5502 this in client library and in server.
5504 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Fixed the WHOIS and IDENTIFY send reply function to really
5507 check whether to send list or just one entry. Affected file
5510 * Cleaned up the LEAVE command's channel key distribution. The
5511 affected file silcd/command.c.
5513 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5514 can enforce the channel mode as well. In that case the ID
5515 includes the ID of the server. The code now enforces the
5516 mode change if the router have different mode than the server.
5518 * The notify client operation with CMODE_CHANGE notify can now
5519 return NULL client_entry pointer if the CMODE was not changed
5520 by client. Application must check for this.
5522 * Added <Server ID> argument to INFO command to support server
5523 info fetching by Server ID.
5525 * Added silc_server_announce_get_channel_users to get assembled
5526 packets of channel users of the specified channel. Affected
5527 file silcd/server.[ch].
5529 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5530 was freed underneath the ID Cache.
5532 * Re-announce clients when the server received CHANNEL_CHANGE
5533 notify from the router. Affected file silcd/packet_send.c.
5535 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5538 crashed since it did not handle the fact that there is no cipher
5539 called "3" and didn't check the error condition. Now fixed.
5541 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5542 flag. It can be used to send message requests.
5544 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Implemented the RESTART command in the client.
5548 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5549 notice type messages. Added notice printing to the user
5552 * The channel keys are not re-generated if the channel's mode
5553 is PRIVKEY, ie private key on the channel exists. Affected
5554 files silcd/server.c and silcd/command.c.
5556 * Fixed a little bug in channel message delivery when channel
5557 private keys are set in the server. Affected file is
5558 silcd/packet_send.c.
5560 * Changed the setting on channel->on_channel = TRUE from the
5561 silc_client_save_channel_key to the JOIN command reply. The
5562 key payload is not received if the private channel key is set.
5563 Affected file lib/silcclient/command_reply.c and the
5564 lib/silcclient/client_channel.c.
5566 * When the CMODE_CHANGE notify is sent and the channel private
5567 key mode is removed the channel key must be re-generated in
5568 other cells as well. Added this support for the router in the
5569 silcd/packet_receive.c.
5571 * Added new local command NOTICE to send notice message on
5572 channel. Affected file silc/local_command.[ch].
5574 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Added new local command ME to the client. It is used to send
5577 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5578 some action. Affected file silc/local_command.[ch].
5580 * Changed channel_message and private_message client operations
5581 to deliver the message flags to the application. Added also
5582 the `flags' arguments to the silc_client_send_channel_message
5583 and silc_client_send_private_message functions. Affected file
5586 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Redefined the Private Message Payload to support private message
5589 keys and to support the new private message flags. Updated
5590 the protocol specs. Flags makes it possible to have for example
5591 CTCP style messages.
5593 * Added new type SilcPrivateMessagePayload and defined an API
5594 for it in the lib/silcclient/silcprivate.[ch].
5596 * Tested private message private keys successfully. Tested the
5597 private message key set, unset and list commands with the new
5600 * Redefined the Channel Message Payload to include the channel
5601 message flags (equal with private message flags) to support
5602 for example CTCP style messages.
5604 * Defined some of the message (for channel and private message)
5605 flags. Updated the protocol specs and added the flags to the
5606 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5608 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Added SilcKeyAgreementStatus type to the key agreement routines
5611 to indicate the current status and error if one occured.
5612 The status types are defined in the lib/silcclient/silcapi.h.
5614 * Added new local command KEY that is used to set and unset private
5615 keys for channels, set and unset private keys for private messages
5616 with remote clients and to send key agreement requests and
5617 negotiate the key agreement protocol with remote client. The
5618 key agreement is supported only to negotiate private message keys,
5619 it currently cannot be used to negotiate private keys for channels,
5620 as it is not convenient for that purpose.
5622 * Fixed a minor pending callback setting bug in the function
5623 silc_client_get_client_by_id_resolve, now the function works.
5624 Affected file lib/silcclient/idlist.c.
5626 * Added function silc_net_get_local_port to get local bound
5627 port by socket. Added to lib/silcutil/silcnet.[ch].
5629 * Added `sockets' and `sockets_count' fields to the SilcClient
5630 object. They hold the sockets of the listenning sockets in
5631 the client. Listenning sockets may be for example the key
5632 agreement server. Affected file lib/silcclient/client.[ch].
5633 Added functions the silc_client_add_socket and the
5634 silc_client_del_socket. They are exported to the application
5637 * Added ~./silc/clientkeys to support other client's public keys.
5639 * Renamed verify_server_key client operation to verify_public_key
5640 and added one argument to indicate the type of the connection
5641 (server, client etc.).
5643 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5645 * Added silc_server_connection_auth_request to handle the
5646 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5647 silcd/packet_receive.[ch].
5649 * Added silc_server_send_connection_auth_request into the
5650 silcd/packet_send.c to send the connection auth request packet.
5652 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5655 * Fixed the public key authentication in responder side in the
5656 server. The `auth_data' pointer includes the SilcPublicKey
5657 not the path to the public key. Affected file silcd/protocol.c.
5659 * Implemented the public key authentication in the initiator side
5660 in the server. Affected file silcd/protocol.c.
5662 * Removed the [RedirectClient] config section from the server
5663 configuration. Is not needed and I don't want to implement it.
5665 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Cleaned up the CMODE command in the server. It now works
5668 correctly and supports all the modes defined in the protocol.
5669 Affected file is silcd/command.c.
5671 * Added `hmac_name' field to the SilcChannelEntry in the server
5672 to hold the default HMAC of the channel. It can be set when
5673 creating the channel (with JOIN command). Affected files
5676 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5677 type to indicate the change of the current cipher and hmac
5678 on the channel. Client can safely ignore the <cipher> argument
5679 (if it chooses to do so) since the CHANNEL_KEY packet will
5680 force the channel key change anyway. The <hmac> argument is
5681 important since the client is responsible of setting the new
5682 HMAC and the hmac key into use.
5684 * Fixed the CMODE command in the client library as well.
5686 * Tested CMODE command in router environment successfully.
5688 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Show the version of the remote client (or server) when connecting
5691 to the server. It is logged to the log file. Affected file
5692 is silcd/protocol.c.
5694 * Fixed the KILLED notify handling in the client library. The
5695 client must be removed from all channels when receiving the
5698 Also, do not remove the client entry when giving the KILL
5699 command but when the KILLED notify is received.
5701 * Removed silc_idlist_find_client_by_nickname from the server.
5702 Not needed anymore. Affected files silcd/idlist.[ch].
5704 * Implemented the CHANNEL_CHANGE notify type handling to the
5705 server. Affected file silcd/server.c.
5709 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Added silc_server_send_notify_invite to send the INVITE
5712 notify between routers.
5714 * Implemented the INVITE command correctly to the server.
5716 * Implemented the INVITE notify type handling in the server.
5718 * Implemented the INVITE command to the client library and on the
5721 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Added function silc_server_get_client_resolve to find the
5724 client entry by ID from all ID lists and then resolve it
5725 (using WHOIS) if it cannot be found. Affected file is
5728 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Implemented the BAN command to the client library.
5732 * The JOIN command in the server now checks the invite list
5735 * Changed the silc_command_reply_payload_encode_va and the
5736 silc_command_payload_encode_va to support that if argument is
5737 NULL it ignores and checks the next argument. Affected file
5738 lib/silccore/silccommand.c.
5740 * Added silc_server_send_notify_ban to send the BAN notify
5741 type between routers.
5743 * Chaned the silc_notify_payload_encode to support that if
5744 argument is NULL it ignores and checks the next argument.
5745 Affected file lib/silccore/silcnotify.c.
5747 * Tested ban lists in router environment successfully.
5749 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Implemented BAN command to the server, in silcd/command.[ch].
5753 * Removed the BAN and INVITE_LIST modes from the CMODE command
5756 * Added function silc_string_match to regex match two strings.
5757 Affected files lib/silcutil/silcutil.[ch].
5759 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Redefined parts of the SilcChannelEntry in the server to support
5762 the new ban and invite lists.
5764 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Redefined the INVITE command. The same command can be used to
5767 invite individuals to the channel but also to manage the invite
5768 list of the channel (to add to and remove from the invite list).
5769 Updated the protocol specs.
5771 * Added new command SILC_COMMAND_BAN that can be used to manage
5772 the ban list of the channel. Updated the protocol specs.
5774 * Removed the channel modes: the SILC_CMODE_BAN and the
5775 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5776 in the CMODE command. The equivalent features are now available
5777 using INVITE and BAN commands. Updated the protocol specs.
5779 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5780 in the network about change in the current ban list. The notify
5781 type is not used by the client.
5783 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5784 support the invite lists.
5786 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * Added new function silc_string_regexify that converts string
5789 including wildcard characters into regex string that can
5790 be used by the GNU regex library. Added into the file
5791 lib/silcutil/silcutil.[ch].
5793 Added silc_string_regex_combine to combine to regex strings
5794 into one so that they can be used as one regex string by
5795 the GNU regex library. Added into the file
5796 lib/silcutil/silcutil.[ch].
5798 Added silc_string_regex_match to match two strings. It returns
5799 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5801 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Imported GNU regex to the soruce tree into lib/contrib.
5804 Fixed some compiler warning from the regex.c.
5806 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed MOTD command in the server to work in router environment.
5810 * Fixed the MOTD command in the client library to support
5811 the server argument in the command.
5813 * Added `nickname_len' argument to the silc_idlist_add_client
5814 in the server, as the `nickname' argument may be binary data
5817 * Added silc_idlist_get_channels to return all channels from
5820 * Implemented LIST command to the server. Affected file is
5823 * Implemented the LIST command to the client library and on the
5826 * Added [<user count>] argument to the LIST command reply.
5827 With private channels the user count is not shown.
5829 * Updated TODO and README.
5831 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * The client entry's data.registered must be TRUE even with
5834 global client entry on global client list. The data.registered
5835 is used to check whether the client is anymore in the network,
5836 for example with WHOWAS command so it must be valid.
5838 * Fixed the WHOWAS command in the server. It now actually works
5839 in router environment. Added function into silcd/command_reply.c
5840 silc_server_command_reply_whowas_save.
5842 * Added silc_idlist_purge function to the silcd/idlist.c
5843 to periodically purge the ID Cache.
5845 * Fixed INFO command in the server. It works now in router
5846 environment. Added <server name> argument to the INFO command
5847 reply. Updated the protocol specs.
5849 * Fixed minor bug in silc_idcache_purge to not purge if the
5850 expire value is zero.
5852 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5853 they were buggy because of the WHOWAS information.
5855 * Fixed local command MSG to handle the async resolving of
5856 the remote client properly. It used to fail the first MSG.
5857 Affected file silc/local_command.c.
5859 * Added `data_len' field to SilcIDCache context.
5861 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Update TODO. Todo in commands in the server.
5865 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5868 used by routers as broadcast packet to inform other routers
5869 about the changed user mode.
5871 Implemented the notify handling in the server. Affected file is
5872 silcd/packet_receive.c. Added the function
5873 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5875 * Added new generic Channel Payload and deprecated the New Channel
5876 Payload. The New Channel Payload is now the generic Channel
5879 * Added new argument `mode' to the silc_server_send_new_channel
5880 as it is required in the Channel Payload now.
5882 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5883 and created a new and real SilChannelPayload to represent the
5884 new generic Channel Payload. Implemented the encode/decode
5885 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5887 * Added silc_server_get_client_channel_list to return the list
5888 of channels the client has joined for WHOIS command reply.
5889 Affected file silcd/server.[ch].
5891 * Implemented the channel list sending in the WHOIS command reply
5892 in server and in the client.
5894 Implemented the channel list displaying on the user interface
5895 as well. Affected file silc/client_ops.c.
5897 * Added silc_channel_payload_parse_list to parse list of Channel
5898 Payloads. It returns SilcDList list of SilcChannelPayloads.
5899 Client for example can use this function to parse the list of
5900 channels it receives in the WHOIS command reply. The caller
5901 must free the list by calling silc_channel_payload_list_free.
5902 Affected files lib/silccore/silcchannel.[ch].
5904 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added one new argument <user mode> to the WHOIS command reply
5907 to return the mode of the user in SILC. Updated the protocol
5910 Implemented it to the server and client.
5912 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Fixed the mode printing on the user interface on joining.
5915 Affected file silc/client_ops.c.
5917 * Implemented the UMODE command and user modes in general to the
5918 client library and to the user interface.
5920 * Implemented the UMODE command to the server.
5922 * The server now sends UNKNOWN_COMMAND error status if client sends
5923 unknown command. Affected file silcd/command.c.
5925 * All server commands now handle the command identifier the right
5926 way when sending the command reply to the client. The client can
5927 use to identify the command replies with the identifier.
5929 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added silc_server_get_client_route to resolve the route to
5932 the client indicated by the client ID. Affected file is
5935 * Added silc_server_relay_packet as general function to relay
5936 packet to arbitrary destination. This deprecates functions
5937 like _send_private_message_key, _relay_notify etc. Affected
5938 file is silcd/packet_send.[ch].
5940 Removed silc_server_send_key_agreement,
5941 silc_server_send_private_message_key and
5942 silc_server_packet_relay_notify functions from the file
5943 silcd/packet_send.[ch].
5947 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5948 server. Affected file silcd/packet_receive.[ch].
5950 * Implemented the KILL command to the client. Implemented the
5951 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5952 Affected files lib/silcclient/command[_reply].c and
5953 lib/silcclient/client_notify.c. Implemented the KILL notify
5954 printing in the user inteface.
5956 * Fixed a lot silc_parse_nick memory leaks from the client
5957 library in the file lib/silcclient/command.c.
5959 * Changed the silc_server_send_notify_on_channels's `sender'
5960 argument from SilcSocketConnection to SilcClientEntry to
5961 check the sender as entry and not as connection object and not
5962 to send to the client provided as argument. The affected file
5963 is silcd/packet_send.[ch].
5965 * The notify packets that are destined directly to the client used
5966 to not to be processed by the server. Now changed that and the
5967 server processes all notify packets. After relaying the packet
5968 to the client the notify packet is processed in the server.
5970 * The silc_server_free_client_data now checks whether there is
5971 pending outgoing traffic for the client and purges the data to
5972 the network before removing the client entry.
5974 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5977 an client is killed from the SILC Network. Updated the protocol
5980 Added new function silc_server_send_notify_killed to the
5981 silcd/packet_send.[ch].
5983 * Added function silc_server_packet_relay_notify to relay notify
5984 packets that are destined directly to a client. In this case
5985 the server does not process the notify packets but merely relays
5986 it to the client. Affected file silcd/packet_send.[ch].
5988 Added also silc_server_packet_process_relay_notify to check
5989 whereto relay the notify. Affected file is
5990 silcd/packet_receive.[ch].
5992 * Implemented the KILL command to the server.
5996 * Added the backup schema desgined last fall to the protocol
5997 specs for everyone to see. The specification is in the
5998 *-spec-xx.txt draft and the packet type definitions for the
5999 backup routers is in *-pp-xx.txt draft. Thusly, added also
6000 new packet type SILC_PACKET_CELL_ROUTERS.
6002 * A big security problem in the implementation discovered. The
6003 signoff of an client did not cause new channel key generation
6004 which it of course should've done. The channel keys must be
6005 always re-generated when client leaves (or signoffs) the channel.
6006 The silc_server_remove_from_channels funtion now handles
6007 the channel key re-generation.
6009 * Added `sender' argument to the silc_server_send_notify_on_channels
6010 to not to send the client provided as argument. Affected file
6011 silcd/packet_send.[ch].
6013 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6015 * Implemented OPER and SILCOPER commands into the server and
6018 * Added silc_auth_verify and silc_auth_verify_data to verify
6019 the authentication directly from the authentication payload.
6020 It supports verifying both passphrase and public key based
6021 authentication. Affected file lib/silccore/silcauth.[ch].
6023 * Added `hash' field to the SilcIDListData structure. It is the
6024 hash negotiated in the SKE protocol. Affected file is
6027 * Slight redesigning of the SilcAuthPayload handling routines.
6028 Do not send SilcPKCS but SilcPublicKey as argument.
6030 * Implemented the public key authentication support to the
6031 serverconfig. The public key is loaded from the provided path
6032 and saved as authentication data to void * pointer. Thus,
6033 changed the unsigned char *auth_data to void *auth_data;
6035 * Fixed SHUTDOWN command to send the reply before the server
6036 is shutdown. :) Affected file silcd/command.c.
6038 * Fixed fatal bug in CONNECT command. The hostname was invalid
6039 memory and server crashed. Affected file silcd/command.c.
6041 * Fixed fatal bug in CLOSE command. The server_entry became
6042 invalid but was referenced later in the command. Affected file
6045 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6047 * Fixed fatal bug in failure packet handling. Server ignored
6048 the failure and thus crashed when it came.
6052 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6055 that the command may be executed only once in (about) 2 seconds.
6056 The old SILC_CF_LAG flag is same but allows command bursts up
6057 to five before limiting.
6059 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6060 server code. Various commands now includes the CF_LAG_STRICT
6061 flag to disallow any kind of miss-use of the command.
6063 * Fixed the silc_buffer_unformat to not to allocate any data
6064 if the length of the data is zero. It used to allocate the
6065 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6067 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Changed the format of AdminConnection configuration section
6070 in the server. Added username of the admin to the format.
6071 Affected files silcd/serverconfig.[ch].
6073 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6074 to return admin configuration data by host, username and/or
6077 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * Implemented WHOWAS command to the server. Added the functions:
6081 silc_server_command_whowas_parse,
6082 silc_server_command_whowas_send_reply,
6083 silc_server_command_whowas_from_client and
6084 silc_server_command_whowas_from_server
6086 * Added <Client ID> argument to the WHOWAS command reply. Updated
6087 the protocol specs accordingly.
6089 * Implemented WHOWAS command and command_reply to the client
6092 Implemented the WHOWAS printing on the user interface.
6094 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Added new argument to the WHOWAS command reply, the real name.
6097 It is an optional argument. Updated the protocol specs.
6099 * Added SilcIDCacheDestructor callback that is registered when
6100 the SilcIDCache is allocated. The callback is called when
6101 an cache entry in the ID Cache expires, or is purged from the
6102 cache. Added into lib/silccore/idcache.[ch].
6104 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6105 to destruct the client entries when the cache entry expires.
6106 Other ID Cache's in server and in the client library ignores
6109 * If the ID Cache entry's `expire' field is zero then the entry
6110 never expires. Added boolean `expire' argument to the
6111 silc_idcache_add function in the lib/silccore/idcache.[ch].
6112 If it is TRUE the default expiry value is used.
6114 * Added silc_server_free_client_data_timeout that is registered
6115 when client disconnects. By default for 5 minutes we preserve
6116 the client entry for history - for WHOWAS command.
6118 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Added support to the server to enforce that commands are not
6121 executed more than once in 2 seconds. If server receives
6122 commands from client more frequently, timeout is registered
6123 to process the commands. Affected file silcd/command.c.
6124 Added new function silc_server_command_process_timeout.
6126 * Changed NICK_NOTIFY handling in client library to check that
6127 if the client's nickname was changed, so there is no need to
6128 resolve anything from the server.
6130 * Removed error printing from the WHOIS and IDENTIFY commands.
6131 If error occurs then it is ignored silently in the client library.
6132 The application, however, may map the received error to
6133 human readable error string. The application currently maps
6134 the NO_SUCH_NICKNAME error to string.
6136 * Made the command status message public to the application. Moved
6137 them from lib/silcclient/command_reply.c to
6138 lib/silcclient/command_reply.h. The application can map the
6139 received command status to the string with the
6140 silc_client_command_status_message function.
6142 * Added check to the server to check that client's ID is same
6143 as the Source ID in the packet the client sent. They must
6146 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Added dist-bzip hook to the Makefile.am to make bzip2
6149 compressed distributions.
6151 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6153 * Server now enforces the maximum length for the nickname and
6154 the channel as protocol specification dictates. 128 bytes for
6155 nickname and 256 bytes for channel name.
6157 * Moved the WHOIS printing to the application. The client libary
6158 does not print out the WHOIS information anymore, the application
6159 must do it. Renamed silc_client_command_reply_whois_print to
6160 the silc_client_command_reply_whois_save.
6162 The client's idle time is also sent to the application now, and
6163 the idle is shown on screen.
6165 * Added silc_client_command_reply_identify_save to save the
6166 received IDENTIFY entries.
6168 * Do not check for channel private keys in message sending and
6169 reception if the channel does not have the PRIVKEY mode set.
6170 Affected file lib/silclient/client_channel.c.
6172 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6175 just surfaced after chaning the JOIN procedure.
6177 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Added silc_client_get_clients_by_list to get client entries
6180 from Client ID list, that is returned for example by JOIN
6181 and USERS command replies. The application should use this
6182 function for example when JOIN command reply is received to
6183 resolve the clients already on the channel (library does not
6184 do that anymore as USERS command reply is not used in the JOIN
6185 procedure anymore). Affected files lib/silcclient/silcapi.h and
6186 lib/silcclient/idlist.c.
6188 * JOIN command reply and USERS command reply returns now SilcBuffer
6189 pointers instead of unsigned char pointers when returning
6190 the client list and mode list.
6192 * Added <Client ID> argument to the JOIN command reply, mainly
6193 for the server to identify for which client the command was
6194 originally sent. Updated protocol specs accordingly.
6196 * Added SilcDlist private_key pointer to the SilcChannelEntry
6197 in the client to support the channel private keys. Affected
6198 file is lib/silcclient/idlist.h.
6200 * Added SilcChannelPrivateKey argument to the function
6201 silc_client_send_channel_message so that application can choose
6202 to use specific private ke if it wants to. If it is not provided,
6203 the normal channel key is used, unless private keys are set.
6204 In this case the first (key that was added first) is used
6205 as the encryption key.
6207 * Implemented the support for channel private key handling.
6208 Implemented the following functions:
6210 silc_client_add_channel_private_key,
6211 silc_client_del_channel_private_keys,
6212 silc_client_del_channel_private_key,
6213 silc_client_list_channel_private_keys and
6214 silc_client_free_channel_private_keys
6216 Affected file lib/silcclient/client_channel.c.
6218 * Added the support for the private keys in the channel message
6219 sending and encryption and in the message reception and
6220 decryption. Affected funtions are
6221 silc_client_send_channel_message and silc_client_channel_message.
6223 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Added SKE's key verify callback to the client library's
6226 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6228 * Removed the statement that server (or router) must send USERS
6229 command reply when joining to the channel so that the client
6230 knows who are on the channel. Instead, the client list and
6231 client's mode list is now sent in the JOIN command reply to the
6232 client who joined channel. This is better solution.
6234 * Added function silc_server_get_users_on_channel and function
6235 silc_server_save_users_on_channel to the silcd/server.[ch].
6237 * Removed function silc_server_command_send_users from the
6240 * Do not show topic on the client library anymore. The topic is
6241 sent in the command reply notify to the application and the
6242 application must show the topic now.
6244 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Added client searching by nickname hash into the IDENTIFY and
6247 WHOIS commands in the server as they were clearly missing from
6248 them. Affected file is silcd/command.c.
6250 * Fixed a bug in private message receiving in the client library.
6251 The remote ID was freed and it wasn't supposed, now it is
6254 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Minor fix to the channel payload; allocate the data area, as it
6257 needs to be of specific length.
6259 * If the key agreement port is zero then the operating
6260 system will define the bound port. Affected files are
6261 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6263 * Added new function silc_channel_payload_decrypt into the file
6264 lib/silccore/silcchannel.[ch].
6266 * Moved the channel message etc, check from silc_packet_decrypt
6267 to applications. The library calls now a generic
6268 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6269 when the packet is either normal or special. This was done to
6270 allow more wide range of checking that was not allowed when
6271 the code was in library. Now applications can do virtually any
6272 checks to the packet and return to the library the decision how
6273 the packet should be processed. Affected files are
6274 lib/silccore/silcpacket.[ch].
6276 Added silc_server_packet_decrypt_check to the server and
6277 silc_client_packet_decrypt_check to the client library.
6279 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6280 to send with specified source and destination information.
6282 * Channel message delivery between routers was broken after the
6283 channel key distribution was fixed earlier. The channel key
6284 was used be to distributed to other routers as well which is not
6285 allowed by the protocol. Now this is fixed and channel keys
6286 really are cell specific and the channel message delivery between
6287 routers comply with the protocol specification.
6289 * Fixed various commands in server to check also the global list
6290 for the channel entry and not just the local list. The affected
6291 file silcd/command.c.
6293 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6295 * Added assert()s to buffer formatting and unformatting routines
6296 to assert (if --enable-debug) when error occurs. Affected
6297 file: lib/silcutil/silcbuffmt.c.
6299 * Changed to auto-reconnect to check whether the remote host is
6300 router and register the re-connect timeout if it is. It used
6301 to check that whether we are normal server, but router must do
6302 auto-reconnect with another router as well. Affected file
6305 * Removed the [<key len>] option from CMODE command as the cipher
6306 name decides the key length, nowadays. See the defined ciphers
6307 from the protocol specification.
6309 * Added [<hmac>] option to the CMODE command to define the HMAC
6310 for the channel. Added SILC_CMODE_HMAC channel mode.
6312 * Added [<hmac>] option for the JOIN command so that user can
6313 select which HMAC is used to compute the MACs of the channel
6316 * Added Hmac field to the Channel Message Payload. The integrity
6317 of plaintext channel messages are now protected by computing
6318 MAC of the message and attaching the MAC to the payload. The
6319 MAC is encrypted. Now, it is clear that this causes some
6320 overhead to the size of the packet but rationale for this is that
6321 now the receiver can verify whether the channel message decrypted
6322 correctly and also when private keys are set for the channel the
6323 receiver can decrypt the packet with several keys and check from
6324 the MAC which key decrypted the message correctly.
6326 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6327 lib/silccrypt/silccipher.[ch].
6329 * Added silc_hash_len to return the digest length into the
6330 lib/silcrypt/silchash.[ch].
6332 * Rewrote parts of Silc Channel Payload interface in the
6333 lib/silccore/silcchannel.[ch]. The encode function now also
6334 encrypts the packet and parse function decrypts it.
6336 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Fixed a minor formatting bug in the SKE's key material processing.
6339 It actually might have processed the keys wrong way resulting
6342 * Redefined the mandatory HMAC algorithms and added new algorithms.
6343 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6344 and hmac-md5 truncated to 96 bits. The mandatory is now
6345 hmac-sha1-96. Rest are optional (including the one that used
6346 to be mandatory). Rationale for this is that the truncated HMAC
6347 length is sufficient from security point of view and can actually
6348 make the attack against the HMAC harder. Also, the truncated
6349 HMAC causes less overhead to the packets. See the RFC2104 for
6352 * Added new [hmac] configuration section. The SKE used to use
6353 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6354 is of course wrong. The official names that must be proposed in
6355 the SKE are the ones defined in the protocol specification
6356 (hmac-sha1-96 for example). The user can configure any hmac
6357 using any hash function configured in the [hash] section. At
6358 least, the mandatory must be configured.
6360 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6362 * Added HMAC list to the SKE proposal list. It has now both
6363 hash algorithm list and HMAC list. This makes the protocol
6364 incompatible with previous versions. The SKE now seems to work
6365 the way it is supposed to work, for the first time actually.
6367 * Defined plain Hash algorithms to the protocol specification.
6370 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6372 * Implemented support for key agreement packets into the server.
6373 Added functions silc_server_key_agreement and
6374 silc_server_send_key_agreement. Other than these functions,
6375 server has nothing to do with this packet.
6377 * Added support for private message key packets into the server.
6378 Added functions silc_server_private_message_key and
6379 silc_server_send_private_message_key.
6383 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6384 called in the protocol's final callback instead in the END
6385 protocol state. This makes a little more sense and in the same
6386 time in client we can use the same protocol routines for normal
6387 key exchange and to key agreement packet handling as well.
6389 * Added to both client's and server's KE protocol context the
6390 SilcSKEKeyMaterial pointer to save the key material. We will
6391 bring the key material to the protocol's final callback by doing
6392 this. The final callback must free the key material.
6394 * Added SKE's packet_send callback into client's KE protocol
6395 context so that the caller can choose what packet sending function
6396 is used. This way we can use different packet sending when
6397 doing normal SKE when doing key agreement packet handling (in
6398 the key agreement packet handling we do not want to encrypt
6401 * Implemented the responder side of the key agreement routines
6402 in the client. The client can now bind to specified port and
6403 accept incoming key negotiation. The key material is passed
6404 to the application after the protocol is over.
6406 * Implemented the processing of incoming Key Agreement packet
6407 in the client. Added function silc_client_key_agreement to
6410 * Implemented the intiator side of the key agreement routines
6411 in the client. The client can now initiate key agreement with
6412 another remote client. The key material is passed to the
6413 application after the protocol is over.
6415 * Created client_keyagr.c to include all the key agreement
6418 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6419 SILC_TASK_CALLBACK except that it is not static.
6421 * Created client_notify.c and moved the Notify packet handling
6422 from the client.[ch] into that file.
6424 * Created client_prvmsg.c and moved all private message and
6425 private message key routines from the client.[ch] into that file.
6427 * Create client_channel.c and moved all channel message and
6428 channel private key routines from the client.[ch] into that file.
6430 * Changed silc_client_get_client_by_id_resolve to resolve with
6431 WHOIS command instead of IDENTIFY command, in the file
6432 lib/silclient/idlist.c.
6434 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Implemented the SKE's responder side to the Client library.
6438 * When FAILURE is received to the protocol do not trust it
6439 blindly. Register a timeout to wait whether the remote closes
6440 the connection as it should do it, only after that process the
6441 actual failure. This was changed to both client and server.
6443 * Added client_internal.h to include some of the structures
6444 there instead of client.h in lib/silcclient/.
6446 * Added function silc_task_unregister_by_callback to unregister
6447 timeouts by the callback function.
6449 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Some "Incomplete WHOIS info" errors has been appearing on the
6452 log files. Took away the entry->userinfo check from WHOIS
6453 reply sending. The entry->userinfo is now " " if client did not
6454 provide one. I thought this was fixed earlier but something
6455 is wrong still. Let's see if the error still appears.
6457 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Fixed a minor bug in the login when the channel key is
6460 re-generated in the server. It used to generate the key in
6461 wrong order and thus caused problems in the channel traffic.
6463 * Fixed a minor bug in channel key distsribution after
6464 KICK command. The key was not sent to the router even though
6467 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Added silc_ske_process_key_material_data as generic routine
6470 to process any key material as the SILC protocol dictates. The
6471 function is used by the actual SKE library but can be used by
6472 applications as well. This relates to the private message keys
6473 and the channel private keys since they must be processed the
6474 same way the normal SILC session keys. The protocol dictates
6475 this. Affected files: lib/silcske/silcske.[ch].
6477 Added also silc_ske_free_key_material to free the
6478 SilcSKEKeyMaterial structure.
6480 * Defined silc_cipher_set_key function to set the key for
6481 cipher without using the object's method function. The affected
6482 files: lib/silccrypt/silccipher.[ch].
6484 * Implemented silc silc_client_add_private_message_key,
6485 silc_client_add_private_message_key_ske,
6486 silc_client_del_private_message_key,
6487 silc_client_list_private_message_keys and
6488 silc_client_free_private_message_keys functions in the
6491 Added functions silc_client_send_private_message_key to send
6492 the Private Message Key payload and silc_client_private_message_key
6493 to handle incoming Private Message Key payload.
6495 * Added Cipher field to the Private Message Key payload to set
6496 the cipher to be used. If ignored, the default cipher defined
6497 in the SILC protocol (aes-256-cbc) is used.
6499 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Removed lib/silcclient/ops.h file.
6503 Redefined parts of the SILC Client Library API. Created new
6504 file silcapi.h that deprecates the ops.h file and defines the
6505 published Client Library API. Defined also private message key
6506 API and channel private key API into the file.
6508 This is the file that the application must include from the
6509 SILC Client Library. Other files need not be included by
6510 the application anymore.
6512 * Added new key_agreement client operation callback and also
6513 defined the Key Agreement library API for the application.
6515 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6517 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6518 is used by clients to request key negotiation between another
6519 client in the SILC network. If the negotiation is started it
6520 is performed using the SKE protocol. The result of the
6521 negotiation, the secret key material, can be used for example
6522 as private message key.
6524 Implemented the Key Agreement payload into the files
6525 lib/silccore/silauth.[ch].
6527 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6529 * Redefined ciphers for the SILC protocol. Added some new ciphers
6530 and defined the key lengths for the algorithms. Changed the
6531 code accordingly. The default key length is now 256 bits.
6533 * Fixed SKE key distribution function silc_ske_process_key_material
6534 when the key length is more than 128 bits. The default key
6535 length in SILC is now 256 bits.
6537 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6538 to indicate unsupported algorithm.
6540 * Renamed rijndael.c to aes.c and all functions as well.
6542 * Fixed a long standing channel key setting bug in client library.
6543 Weird that it has never surfaced before.
6545 * Fixed bug in channel deletion. If the entire channel is removed
6546 then it must also delete the references of the channel entry
6547 from the client's channel list as the client's channel entry and
6548 the channel's client entry share same memory.
6550 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Implemented CONNECT and SHUTDOWN commands in the client.
6554 * Implemented CLOSE command to the client.
6556 * Added the function silc_idlist_find_server_by_name into the
6557 files silcd/idlist.[ch].
6559 Added the function silc_idlist_find_server_by_conn into the
6560 files silcd/idlist.[ch].
6562 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * DIE command was renamed to SHUTDOWN. Updated the both code
6567 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6568 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6570 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6573 * Added function silc_server_create_connection function to create
6574 connection to remote router. My server implementation actually
6575 does not allow router to connect to normal server (it expects
6576 that normal server always initiates the connection to the router)
6577 so the CONNECT command is only good for connecting to another
6580 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6582 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6583 or some other client was kicked from the channel.
6585 Implemented the handling of the notify type to both client
6588 Implemented silc_server_send_notify_kicked to send the KICKED
6589 notify. It is used to send it to the server's primary router.
6591 * Implemented the KICK command into server and client.
6593 * Added `query' argument to the silc_idlist_get_client function
6594 to indicate whether to query the client from server or not if
6597 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6598 to indicate that the client is not channel founder.
6602 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Removed the rng context from SilcPacketContext structure and
6605 changed that the packet routine uses the Global RNG API.
6607 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Added support for quit message that client can "leave" on the
6610 channel when it quits the SILC. It is ditributed inside the
6611 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6613 Added silc_server_free_client_data that will take the
6614 signoff message as argument.
6616 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6618 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Updated parts of the protocol specification to keep it up
6623 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6625 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6626 payloads in one packet.
6628 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6629 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6630 use now the new List flag.
6632 * Also deprecated the following packet types: REPLACE_ID,
6633 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6635 * Added list support for Notify packet in server.
6637 * Added silc_server_send_notify_channel_change to send the
6638 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6639 the silc_server_send_replace_id.
6641 * Added silc_server_send_notify_nick_change to send the
6642 NICK_CHANGE notify type. Deprecates the function
6643 silc_server_send_replace_id.
6645 * Added silc_server_send_notify_join to send the JOIN notify type.
6646 Deprecates the function silc_server_send_new_channel_user.
6648 * Added silc_server_send_notify_leave to send LEAVE notify type.
6649 Deprecates the function silc_server_send_remove_channel_user.
6651 * Added silc_server_send_notify_cmode and
6652 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6653 types. Deprecates the silc_server_send_set_mode function.
6655 * Added SERVER_SIGNOFF notify type to indicate that server has
6656 quit. This means that all clients on the channel from that
6657 server will drop. This can be also used when netsplit happens.
6659 Deprecated REMOVE_ID packet type since it is not needed anymore
6662 Added silc_server_send_notify_server_signoff to send the
6663 SERVER_SIGNOFF notify type. Deprecates the function
6664 silc_server_send_remove_id.
6666 Added also silc_server_send_notify_signoff to send the
6667 SIGNOFF notify type.
6669 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6670 SILC protocol from this day on. Changed the protocol
6671 specification as well.
6673 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6674 notify type. It is used between routers to notify about
6675 topic changes on a channel.
6677 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6680 * Partly updated the protocol specification to comply with the
6681 changes now made. It is still though a bit outdated.
6683 * The JOIN notify type now takes one extra argument <Channel ID>.
6684 The packet used to be destined to the channel but now the
6685 JOIN type may be sent as list thus it is impossible to
6686 destine it to any specific channel. By adding this argument
6687 it is again possible.
6689 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Added CREDITS file. The CHANGES and CREDITS file will appear
6692 in the distribution as well.
6694 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6697 types in the server's silcd/packet_receive.c.
6699 * Implemented CMODE and CUMODE to work in router environment.
6701 * Fixed minor encoding and decoding buglet from the
6702 lib/silccore/silcmode.c.
6704 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6707 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6709 * Changed all SilcConfigServer* and silc_config_server* to
6710 SilcServerConfig* and silc_server_config*, respectively.
6713 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6715 * Associated the ID (client or server ID) to the Authentication
6716 Payload to avoid any possibility of forging. Updated the
6717 protocol specification and the code accordingly.
6719 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * The RSA key length is now save to the RsaKey context in the
6722 key generation process in lib/silccrypt/rsa.c. The key length
6723 is now used to figure out the maximum size of the block allowed
6724 to be encrypted/signed.
6726 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6727 is equivalent to the silc_mp_mp2bin but does not allocate any
6730 * Changed silc_mp_mp2bin API to take length argument. If it is
6731 non-zero then the buffer is allocated that large. If zero, then
6732 the size is approximated using silc_mp_sizeinbase, which however
6735 * Created Global RNG API which is global RNG that application can
6736 initialize. After initializing, any routine anywhere in the
6737 code (including library) can use RNG without allocating a new
6738 RNG object. This was done to allow this sort of use of the
6739 RNG in code that has no chance to allocate RNG object. All
6740 applications currently allocate this and many routines in the
6741 library use this. Affected file lib/silccrypt/silcrng.[ch].
6743 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6744 it to use the Global RNG API.
6746 * Defined Authentication Payload into protocol specification that
6747 is used during SILC session to authenticate entities. It is
6748 used for example by client to authenticate itself to the server
6749 to obtain server operator privileges.
6751 Implemented this payload into the lib/silccore/silcauth.[ch].
6752 Implemented also routines for public key based authentication
6753 as the new protocol specification dictates.
6755 Moved definitions of different authentication methods from
6756 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6758 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6759 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6760 silc_pkcs_verify_with_hash functions into the file
6761 lib/silccrypt/silcpkcs.[ch].
6763 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * The client entry's userinfo pointer must be always valid.
6766 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6767 will fail since it requires the userinfo. Now, the userinfo
6768 is allocated as "" if actual userinfo does not exist. Actually,
6769 it must exist and it is totally Ok to drop client connections
6770 that does not announce the userinfo. However, we will make
6771 this workaround for now.
6773 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6774 to return the remote port by socket.
6776 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6779 SILC_SERVER_PENDING_EXEC and added an new macro
6780 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6781 data or when error occurs while processing the pending command.
6783 Added new argument `destructor' into silc_server_command_pending
6784 and to the SilcServerCommandPending object. This destructor is
6785 now called after calling the pending callback or if error occurs
6786 immediately. If error occurs the actual pending callback won't
6787 be called at all - only the destructor. The destructor may be
6788 NULL if destructor is not needed.
6790 All this applies for client library code as well. Similar
6791 changes were made there as well for the pending commands.
6793 In the client, the application must now allocate the
6794 SilcClientCommandContext with the silc_client_command_alloc
6797 * Added reference counter to the SilcServerCommandContext. Added
6798 function silc_server_command_alloc and silc_server_command_dup
6801 Same type of functions added to the client library for the same
6804 * Removed the cmd_ident from IDListData away since it is now
6805 global for all connections. It is the command identifier used
6806 in command sending and with pending commands. The affected file
6809 * Added reference counter to the SilcSocketConnection objecet to
6810 indicate the usage count of the object. The object won't be
6811 freed untill the reference counter hits zero. Currently only
6812 server uses this, and client ignores it. The client must be
6813 set to use this too later. The affected files are
6814 lib/silccore/silcsockconn.[ch]. Added also the function
6815 silc_socket_dup to increase the reference counter.
6817 This was mainly added because it is possible that the socket
6818 is removed underneath of pending command or other async
6819 operation. Now it won't be free'd and proper DISCONNECTING
6820 flags, etc. can be set to avoid sending data to connection that
6821 is not valid anymore.
6823 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6824 the connection. After that it sets SILC_SET_DISCONNECTED.
6825 It is, however, possible that the socket data is not still freed.
6826 The silc_server_packet_process now checks that data is not
6827 read or written to connection that is DISCONNECTED. The socket
6828 get's freed when the reference counter hits zero.
6830 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Changed the client operation API: channel_message operation's
6833 `sender' is now the client entry of the sender, not the nickname
6834 and the `channel' is the channel entry, not the channel name.
6836 In the private_message operation the `sender' is now also the
6837 client entry of the sender not the nickname.
6839 Affected file is lib/silcclient/ops.h and all applications
6840 using the client operations.
6842 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Moved the calling of ops->connect() from connect_to_server_final
6845 into receive_new_id functin since that is the point when the
6846 client is actually allowed to send traffic to network. The
6847 affected file is lib/silcclient/client.c.
6849 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6851 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6852 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6853 (if needs broadcasting) instead of broadcasting the packets one
6854 by one which would make a burst in the network traffic.
6856 * Added `broadcast' argument to the functions in silcd/server.[ch]
6857 silc_server_create_new_channel[_with_id] to indicate whether
6858 to send New Channel packet to primary router.
6860 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6862 * Added new function into the silcd/server.[ch] files:
6863 silc_server_create_new_channel_with_id to create new channel with
6864 already existing Channel ID.
6866 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6867 lib/silccore/silcpacket.h. This packet is used t send list of
6868 Set Mode payloads inside one packet. Server uses this to set
6869 the modes for the channels and clients on those channels, that it
6870 announced to the router when it connected to it. The protocol
6871 specification has been updated accordingly.
6873 * The silc_server_new_channel did not handle the packet coming
6874 from normal server as it normally does not send that. However,
6875 when it announces its channels it does send it. Implemented
6876 the support for that.
6878 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6879 into the file lib/silccore/id.h.
6881 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Fixed memory leaks in the functions silc_idlist_del_client,
6884 silc_idlist_del_channel and silc_idlist_del_server in the file
6885 silcd/idlist.c. All of those leaked like a sieve.
6887 * Fixed some small memory leaks in the client's function
6888 silc_client_notify_by_server.
6890 * Added functions into silcd/server.c: silc_server_announce_clients,
6891 silc_server_announce_channels and silc_server_announce_server.
6892 These functions are used by normal and router server to announce
6893 to its primary router about clients, channels and servers (when
6894 router) that we own. This is done after we've connected to the
6897 These functions effectively implements the following packet types:
6898 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6899 and SILC_PACKET_NEW_ID_LIST.
6901 * Added new functions into the silcd/packet_receive.[ch]:
6902 silc_server_new_id_list, silc_server_new_channel_list and
6903 silc_server_new_channel_user_list to handle the incoming
6904 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6906 * Added support of changing Channel ID in the function
6907 silc_server_replace_id. If the server that announces a channel
6908 to the router already exists in the router (with same name but
6909 with different Channel ID), router is responsible to send
6910 Replace ID packet to the server and force the server to change
6911 the Channel ID to the one router has.
6913 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6914 client that the Channel ID has been changed by the router. The
6915 normal server sends this to the client. Client must start using
6916 the new Channel ID as the channel's ID.
6918 Implemented handling of this new type into lib/silcclient/client.c
6919 into the function silc_client_notify_by_server.
6921 * Added new function silc_idlist_replace_channel_id into the files
6922 silcd/idlist.[ch] to replace the Channel ID.
6924 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Call silc_server_command_identify_check always when processing
6927 the IDENTIFY command in silcd/command.c
6929 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6932 send keepalive packets. The packet can be sent by clients,
6933 servers and routers.
6935 Added function silc_socket_set_heartbeat into the file
6936 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6937 If not set, the heartbeat is not performed. The actual
6938 heartbeat is implemented in the low level socket connection
6939 library. However, application is responsible of actually
6942 Added silc_server_send_heartbeat to send the actual heartbeat
6943 packet into silcd/packet_send.[ch]. Server now performs
6944 keepalive with all connections.
6946 * Added silc_task_get_first function into lib/silcutil/silctask.c
6947 to return the timeout task with shortest timeout. There was a bug
6948 in task unregistration that caused problems. TODO has been
6949 updated to include that task system must be rewritten.
6951 * The client library will now resolve the client information when
6952 receiving JOIN notify from server for client that we know but
6953 have incomplete information.
6955 * Rewrote parts of silc_server_remove_from_channels and
6956 silc_server_remove_from_one_channel as they did not remove the
6957 channel in some circumstances even though they should've.
6959 * Encryption problem encountered in server:
6961 The LEAVE command used to send the Channel Key packet to the
6962 router immediately after generating it. However, the code
6963 had earlier sent Remove Channel user packet but not immediately,
6964 ie. it was put to queue. The order of packets in the router
6965 was that Channel Key packet was first and Remove Channel User
6966 packet was second, even though they were encrypted in the
6967 reverse order. For this reason, MAC check failed. Now, this
6968 is fixed by not sending the Channel Key packet immediately but
6969 putting it to queue. However, this is more fundamental problem:
6970 packets that are in queue should actually not be encrypted
6971 because packets that are sent immediately gets encrypted
6972 actually with wrong IV (and thus MAC check fails). So, packets
6973 that are in queue should be encrypted when they are sent to
6974 the wire and not when they put to the queue.
6976 However, the problem is that the current system has not been
6977 designed to work that way. Instead, the packet is encrypted
6978 as soon as possible and left to the queue. The queue is then
6979 just purged into wire. There won't be any fixes for this
6980 any time soon. So, the current semantic for packet sending
6983 o If you send packet to remote host and do not force the send
6984 (the packet will be in queue) then all subsequent packets to the
6985 same remote host must also be put to the queue. Only after the
6986 queue has been purged is it safe again to force the packet
6989 o If you send all packets immediately then it safe to send
6990 any of subsequent packets through the queue, however, after
6991 the first packet is put to queue then any subsequent packets
6992 must also be put to the queue.
6994 Follow these rules and everything works fine.
6996 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Added new function silc_server_remove_clients_by_server to
6999 remove all client entries from ID list when the server connection
7000 is lost. In this case it is also important to invalidate all
7001 client entires as they hold the invalid server entry. This
7002 fixes fatal bug when server has lost connection and will reconnect
7005 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Made some sanity checks to silc_server_daemonise like to check
7008 whether the requested user and group actually exists.
7010 * Added sanity check to SKE's silc_ske_responder_finish to check
7011 that the public and private key actually is valid.
7013 * Invalidate the client's nickname when receiving Replace ID
7014 packet and the Client ID is being replaced. This means that the
7015 server will query the nickname if someone needs it (client)
7018 * Sort the ID Cache in client library when the ID Cache data
7019 has changed (needs sorting).
7021 * Do not allow for SILC client to create several connections to
7022 several servers. The client does not support windows right now
7023 and generating multiple connections causes weird behaviour.
7025 Irssi-silc client does support windows and can handle several
7026 connections without problems, see: www.irssi.org and SILC plugin.
7028 * Fixed some places where client was added to the IDList. The
7029 rule of thumb is following (in order to get everything right):
7030 If the client is directly connected local client then the
7031 `connection' argument must be set and `router' argument must be
7032 NULL to silc_idlist_add_client function. If the client is not
7033 directly connected client then the `router' argument must
7034 bet set and the `connection' argument must be NULL to the
7035 silc_idlist_add_client function.
7037 * The funtion silc_server_packet_send_local_channel actually did
7038 not check whether the client was locally connected or not. It
7039 does that now. Fixed a bug related to LEAVE command.
7041 * Fixed Remove Channel User payload parsing bug in server's
7042 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7044 * The server's silc_server_save_channel_key now checks also the
7045 global ID list for the channel as it might not be in the local
7046 list. Fixed a bug related to LEAVE command.
7048 * Is this the end of the [<unknown>] buglet that has been lurking
7049 around for a long time? A little for loop fix in server's
7050 silc_server_command_whois_parse that is used by both IDENTIFY
7051 and WHOIS command. At least, this was a clear bug and a cause
7052 of one type of [<unknown>] buglet.
7054 * WHOIS and IDENTIFY commands call the function
7055 silc_server_command_[whois/identify]_check function even if
7056 we are not router server.
7058 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * Added --with-gmp configuration option. If set the GMP
7061 is always compiled in the SILC source tree. If not set then
7062 it is checked whether the system has the GMP3 installed. If
7063 it has then the GMP won't be compiled (the system's headers
7064 and library is used), if it doesn't have it then the GMP is
7065 compiled in the SILC source tree.
7067 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7069 * Changed RSA private exponent generation to what PKCS #1
7070 suggests. We try to find the smallest possible d by doing
7071 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7072 not security fix but optimization.
7074 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * Added new config entry [Identity] to fork the server and run
7077 it as specific user and group. A patch from Bostik.
7079 * Imported Dotconf configuration library into lib/dotconf.
7080 This will be used to create the SILC configuration files later.
7081 It will appear in the distsribution after this commit.
7083 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * A big code auditing weekend happening. Auditing code for
7086 obvious mistakes, bugs and errors. Also, removing any code
7089 Removed files for being obsolete:
7091 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7092 inline in the file lib/silcutil/silcbuffer.h)
7094 o lib/silcutil/silcbufutil.c (the header has inline versions)
7096 Changed code to fix possible error conditions:
7098 o The buffer formatting routines now check that the destination
7099 buffer really has enough space to add the data. This applies for
7100 both buffer formatting and unformatting
7101 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7102 unformatting was changed to accomodate following rules:
7103 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7104 sent to the function while XXX_*STRING will not allocate or copy
7105 the data into the buffer. Instead it sets the pointer from the
7106 buffer into the pointer sent as argument (XXX_*STRING used to
7107 require that the pointer must be allocated already). This change
7108 makes this whole thing a bit more consistent and more optimized
7109 (note that the data returned in the unformatting with XXX_*STRING
7110 must not be freed now). The routines return now -1 on error.
7112 o Tried to find all code that use buffer_format and buffer_unformat
7113 and added return value checking to prevent formatting and
7114 especially unformatting errors and possible subsequent fatal
7117 o Changed ske->x and ske->KEY to mallocated pointers in
7118 lib/silcske/silcske.h. Fixed possible data and memory leak.
7120 o Added return value checking to all *_parse* functions. Fixed
7121 many memory leaks as well.
7123 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7124 so that buffer overflows would not happen. All code now also
7125 checks the return value as it can fail.
7127 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Added reconnection support to server if the normal server looses
7130 its connection to the router (for example if router is rebooted).
7131 The server performs normal reconnection strategy implemented
7132 to the server. Affected file silcd/server.c.
7134 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Added new packet type SILC_PACKET_SET_MODE that is used to
7137 distribute the information about changed modes (for clients,
7138 channels and clients channel modes) to all routers in the
7139 network. Updated the protocol specification accordingly.
7141 Added functions into silcd/packet_send.c and
7142 silcd/packet_receive.c: silc_server_send_set_mode,
7143 silc_server_set_mode.
7145 Added new files silcmode.[ch] into lib/silccore that implements
7146 the encoding and decoding of Set Mode Payload. Added new type
7147 SilcSetModePayload. Moved the definitions of different modes
7148 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7150 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Oops, a little mistake in server's connection authentication
7153 protocol. The protocol is not ended with FAILURE but with
7154 SUCCESS if the authentication is Ok. :) Affected file is
7157 * Implemented NICK_CHANGE notify handling in server in the file
7158 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7159 the local clients on the channel. After the changing nickname
7160 in router environment snhould work and the [<unknown>] nickname
7161 should appear no more.
7163 The silc_server_replace_id function that receives the Replace ID
7164 payload now sends the NICK_CHANGE notify type also in the file
7165 silcd/packet_receive.c
7167 * Changed WHOIS and IDENTIFY command to support the maximum amount
7168 of arguments defined in protocol specs (3328 arguments). This
7169 fixed a bug that caused problems when there were more than three
7172 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7174 * Added extra parameter, command identifier, to the
7175 silc_client_send_command so that explicit command identifier
7178 Changed that ID list routines uses specific command identifier
7179 when sending WHOIS/IDENTIFY requests to the server so that they
7180 can be identified when the reply comes back.
7182 Affected files lib/silcclient/command.[ch],
7183 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7185 * Added `sender' argument to silc_server_packet_send_to_channel
7186 to indicaet the sender who originally sent the packet to us
7187 that we are now re-sending. Ignored if NULL. Affected file
7188 silcd/packet_send.[ch].
7190 * Added some server statistics support in silcd/server_internal.h
7191 SilcServerStatistics structure and around the server code. Also
7192 send some nice statistics information when client is connecting
7195 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Fixed channel ID decoding in server's JOIN command reply in
7198 silcd/command_reply.c
7200 * Fixed braodcasting of replace ID payload to not to send it if
7201 we are standalone server in silcd/packet_receive.c.
7203 * Fixed all channel message sending routines to not to send
7204 packets to clients that has router set, since they are routed
7205 separately in the same function earlier. Affects file
7206 silcd/packet_send.c and all channel packet sending functions.
7208 * In USERS reply, res_argv[i] are not allocated, the table
7209 is allocated. Thus changed that free the table, not its
7212 * In server's whois_check and identify_check if the client is
7213 locally connected do not send any WHOIS commands - they are not
7216 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Fixed some minor bugs in client when sending WHOIS command. The
7219 arguments was in wrong order.
7221 * Removed statis function add_to_channel from server in
7222 silcd/command.c that was previously used with the joining but
7225 * Tested USERS command in router environment successfully with two
7226 routers, two servers and two clients.
7228 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Reorganized the USERS command and command reply in client library
7231 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7232 When the command is given by user we register a pending command
7233 callback that will reprocess the command after the reply has been
7234 received from the server. When reprocessing the packet we then
7235 display the information. Thus, the USERS information is displayed
7236 now in the command callback instead of in the command reply
7237 callback. The processing of the command is same as previously
7238 when server has sent the command reply in the JOINing process.
7240 * Added to USERS command in silcd/command_reply.c to join the client,
7241 we didn't use to know about, to the channel after we've created
7242 a client entry for it. Also, for clienet we did know already still
7243 check whether it is on the channel or not and add it if not.
7245 * Removed silc_server_command_join_notify as the function and its
7248 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Changed the client's pending command handling to the same as the
7251 server's pending command handling. It is also now possible to
7252 execute command reply functions from other command reply
7253 function as the function callbacks for commands and command
7254 replies are one and same. The pending commands are not static
7255 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7256 in client connection context. Thus, pending commands are server
7257 connection specific as it is convenient.
7259 Changed the function silc_client_command_pending and
7260 silc_client_command_pending_del and added new function
7261 silc_client_command_pending_check. Removed the
7262 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7265 * Added cmd_ident, current command identifier, to the client
7266 connection context in lib/silcclient/client.h to keep track on
7267 command identifiers used in command sending. Client's command reply
7268 function handling now supports the mandatory command identifiers.
7270 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7271 funtions in client to fully support pending command callbacks.
7273 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7274 as one of the arguments to the application in the command reply
7277 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7278 before first releasing SILC but came back. Now it is removed again
7279 and should come back nomore. The FORWARDED flag was used only
7280 by the JOINing procedure by forwarding the command packet to router.
7281 Now, the JOINing procedure has been changed to more generic (due
7282 to various router environment issues) and FORWARDED is not needed
7283 anymore for anything. The protocol specification is yet to be
7286 Now, removed silc_server_packet_forward from server and the flag
7287 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7289 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7291 * Renamed NAMES command to USERS command. The NAMES was named that
7292 due to historical reasons. Now it is renamed. Also, rewrote
7293 parts of the USERS command. The nickname list is not sent anymore
7294 by the server. Only Client ID and mode lists are sent in the USERS
7295 command. Changed this also to the protocol specification.
7297 The client now resolves the names and stuff after it receives
7298 the USERS list from the server when joining to the channel.
7300 * WHOIS and IDENTIFY commands has been changed to support multiple
7301 Client ID's per command. One can now search for multiple users
7302 in the network by sending only one WHOIS or IDENTIFY command.
7303 Changed the code and the protocol specifications.
7305 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7306 uses silc_server_command_whois_parse to parse the request. */
7308 * If normal server, do not parse the WHOIS and IDENTIFY requests
7309 before sending it to the router. Saves some time.
7311 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7313 * Fixed JOIN command on client library. Wrong number of arguments
7314 used to crash the client.
7316 * Added silc_server_channel_has_global function to check whether
7317 channel has global users or not.
7319 * Added silc_server_channel_has_local function to check whether channel
7320 has locally connected clients on the channel.
7322 * The silc_server_remove_from_one_channel now checks whether the
7323 channel has global users or not after given client was removed from
7324 the channel. It also checks whether the channel has local clients
7325 on the channel anymore. If it does not have then the channel entry
7326 is removed as it is not needed anymore.
7328 * The silc_server_notify now checks on JOIN notify whether the joining
7329 client is one of locally connected or global. If it is global then
7330 the channel has now global users on the channel and that is marked
7331 to the channel entry. Also, it now saves the global client to
7332 global list who is joining and JOINs it to the channel. This is
7333 for normal server, that is.
7335 Changed silc_server_send_notify_on_channel,
7336 silc_server_packet_relay_to_channel and
7337 silc_server_packet_send_to_channel check if we are normal server
7338 and client has router set (ie. global client) do not send the
7339 message to that client, as it is already routed to our router.
7341 * Implemented LEAVE notify type handling in silc_server_notify
7344 * Tested LEAVE command in router environment successfully. Tested
7345 with two routers, two servers and two clients.
7349 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7351 * Implemented SIGNOFF notify type handling in silc_server_notify
7354 * silc_server_remove_id now removes the client entry from all channels
7355 it has joined and thusly sends SIGNOFF notify type.
7357 * Rewrote the NAMES list generation in server by removing two excess
7358 loops. The lists are created now inside one loop.
7360 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7362 * silc_server_remove_channel_user checks now also global list
7363 for channel and client.
7365 * silc_server_new_channel_user checks now both local and global
7366 list for channel and client. Fixed a bug in client id decoding.
7367 Used to decode wrong buffer.
7369 * silc_server_channel_message checks now both local and global
7370 list for channel entry.
7372 * Tested channel joining (hence JOIN) in router environment
7373 successfully. Tested with two routers, two servers and two
7376 * Tested channel message sending in router environment successfully.
7378 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Added silc_server_save_channel_key into server.[ch] to save the
7381 received channel key in Channel Key payload processing. It is
7382 also used in JOIN command reply handling.
7384 Equivalent function silc_client_save_channel_key added into
7385 client.[ch] into client library.
7387 * Changed JOIN command reply to send information whether the channel
7388 was created or not (is existing already) and the channel key
7389 payload. Changed protocol specs accordingly.
7391 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7392 the request was sent by ID and not by nickname. Crashed on
7395 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7398 now correctly save the received data.
7400 * silc_server_free_sock_user_data now notifies routers in the
7401 network about entities leaving the network.
7403 At the same time implemented functions silc_server_remove_id
7404 and silc_server_send_remove_id to receive and send REMOVE_ID
7405 packets. The packet is used to notify routers in the network
7406 about leaving entities. The ID removed will become invalid in
7409 * Added function silc_idlist_del_server into server. Removes and
7410 free's server entry from ID list.
7412 * silc_server_private_message function now checks, if we are router,
7413 that the destination ID really is valid ID, naturally.
7415 * In router when NEW_ID packet is received (for new client) the
7416 hash of the Client ID is saved in the ID Cache but the
7417 client->nickname is set to NULL, instead of putting the hash
7420 IDENTIFY command now also checks that client->nickname must be
7421 valid. If it is not if will request the data from the server who
7422 owns the client. Added new function
7423 silc_server_command_identify_check.
7425 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7426 to set the command to already allocated Command Payload.
7428 * Tested private message sending in router environment with two
7429 routers, two servers and two clients. Fixed minor bugs and now
7432 * Fixed segfault from client's NAMES command. Used to crash if
7435 * Forwarded packets must not be routed even if it is not destined
7436 to the receiver. Changed server code comply with this.
7438 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7440 * Added `require_reverse_mapping' boolean value to ServerParams
7441 structure. If TRUE (not default) the server will require that
7442 the connecting host has fully qualified domain name.
7444 If the reverse mapping is not required and hostname could not be
7445 found the IP address is used as hostname.
7447 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Implemented version string checking to both client and server.
7450 The check is incomplete currently due to the abnormal version
7451 strings used in development version of SILC.
7453 * Changed all command functions in server to use the new
7456 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7458 * Changed char *data to unsigned char *data in ID Cache system to
7459 support binary data as ID Cache data. Changed code to support
7460 binary data in lib/silccore/idcache.c.
7462 * Renamed silc_server_packet_relay_command_reply to
7463 silc_server_command_reply as it is normal packet receiving
7464 function. Rewrote the function to accept command replys for
7465 servers and not only for clients.
7467 * Mark remote router always as registered server if we are connecting
7468 to it. Otherwise, commands sent by the router to us are ignored.
7470 * All ID List find routines now returns the ID Cache Entry pointer
7471 as well if requested.
7473 * WHOIS command works now in router environment, tested with two
7474 routers, two servers and two clients.
7476 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7477 in router environment (as it is almost equivalent to WHOIS) but
7478 hasn't been tested thoroughly. Added new functions:
7480 silc_server_command_identify_parse
7481 silc_server_command_identify_send_reply
7482 silc_server_command_identify_from_client
7483 silc_server_command_identify_from_server
7485 * Disabled route cache adding because adding two different ID's with
7486 same IP replaces the old cache entry thus giving wrong route.
7487 The entry->router->connection is always the fastest route anyway
7488 so route cache may not be needed. Of course, new routes maybe
7489 established after receiving the ID when the entry->router->connection
7490 might not be anymore the most optimal.
7492 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7494 * Add route cache for received ID for fast routing.
7496 * Added silc_server_packet_route to route received packet on router
7497 that is not destined to us.
7499 * Renamed silc_server_get_route to silc_server_route_get.
7501 * Added id_string and id_string_len fields into SilcServer to
7502 include encoded ServerID for fast comparing without excess
7503 encoding of the ID's.
7505 * Cleaned up WHOIS command on server side. Added following static
7508 silc_server_command_whois_parse
7509 silc_server_command_whois_check
7510 silc_server_command_whois_send_reply
7511 silc_server_command_whois_from_client
7512 silc_server_command_whois_from_server
7514 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7515 arguments in command replies. All command functions should be
7516 updated to use this macro.
7518 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7520 * Minor typo fixes on command reply handling on server.
7522 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7524 * Added silc_server_command_add_to_channel internal routine to add
7525 the client to the channel after router has created the channel and
7526 sent command reply to the server.
7528 * Added generic silc_server_send_command to send any command from
7531 * Use static buffer with ID rendering instead of duplicating data.
7533 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7535 * Fixed a channel user mode bug when joining to a channel server gave
7536 everybody channel founder rights, oops.
7538 * We mark ourselves as the router of the incoming server connection
7539 if we are router ourselves. This way we can check in some packet
7540 sending functions whether it is locally connected server. For
7541 incoming router connections we put NULL.
7543 * For router sending packets locally means now always sending the
7544 packet cell wide; to local clients and local servers. For normal
7545 server sending packet locally means sending it to only local
7548 * Fixed the JOIN command to really work in router environment. If the
7549 channel is created it is always created by the router. Router is
7550 also responsible of making the initial joining to the channel,
7551 sending JOIN notify to the sending server and distributing
7552 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7553 does not exist server doesn't do anything else but forward the
7554 command to the router which performs everything.
7556 * Added silc_server_send_channel_key function to send the Channel Key
7559 * Added silc_server_create_channel_key to create new channel key. The
7560 channel key is now re-generated everytime someone joins or leaves
7561 a channel, as protocol dictates. Note: channel->key_len is the
7564 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7566 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7567 packet_receive.[ch] to separate packet sending and receiving
7568 routines. The server.[ch] now includes everything else including
7569 actual packet processing (writing and reading data) and other
7572 Renamed silc_server_private_message_send_internal to
7573 silc_server_send_private_message. The routine is still though
7574 used only to relay private messages as server does not send
7575 private messages itself.
7577 Renamed silc_server_new_channel to silc_server_create_new_channel
7578 and added new function sicl_server_new_channel that handles the
7579 incoming New Channel packet. Added also new sending function
7580 silc_server_send_new_channel to send New Channel Payload.
7582 * Added new function silc_server_notify to process incoming notify
7583 packet to the server/router. Server may then relay the notify
7584 to clients if needed.
7586 * Added new function silc_server_new_channel_user to process incoming
7587 New Channel User packet. Router will redistribute the packet and
7588 send JOIN notify to its local clients and locally connected servers
7589 if needed. Normal server will send JOIN notify to its local client
7590 on same channel when received this packet. Added also corresponding
7591 sending function silc_server_send_new_channel_user to sent the
7594 * Added boolean route argument to send_notif_to_channel and
7595 packet_send_to_channel functions to attempt to route the packet
7596 if it is TRUE and send only locally if it is FALSE.
7598 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7600 * silc_server_replace_id now broadcasts the received replace ID
7601 packet if it is not broadcast packet already. The router must
7602 broadcast to inform other routers about changed ID.
7604 * Added backpointer to server's router into SilcServer context in
7605 silcd/server_internal.h.
7607 * Fixed silc_server_packet_broadcast to send correct broadcast
7610 * The channel key is now distributed to the local client as soon
7611 as it is received from the router (in router environment) so that
7612 no other packet may be sent for the channel until client has
7615 * silc_server_remove_channel_user now broadcasts the received
7616 Remove Channel User packet if it is not broadcast packet already.
7617 The router must broadcast to inform other routers about removed
7620 * Added users field into SilcPacketContext that is a reference count
7621 of the context. One can increase the reference count by calling
7622 silc_packet_context_dup which is now changed to just increase the
7623 reference count instead of duplicating the data. The reference
7624 count is decresed by calling silc_packet_context_free that will
7625 free the data after the reference count hits zero.
7627 For now on the packet context and everything allocated into it
7628 (including the raw packet from network) must be freed by calling
7629 the new silc_packet_context_free function. Added also new function
7630 silc_packet_context_alloc that must be used now to allocate the
7631 context. This also means that if a routine is asynchronous from
7632 silc_[client/server]_packet_parse_type the packet context must
7633 be duplicated by calling silc_packet_context_dup. Otherwise it
7634 gets free'd after silc_[client/server]_packet_parse_type returns.
7635 Also, one must remember that if packet is duplicated then its
7636 reference count must be decresed by calling the free function as
7637 many times as it was duplicated.
7639 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7640 from both client and server.
7642 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Made joining to a channel working in router environment.
7646 * Cleaned up JOIN command on server side and create function
7647 silc_server_command_join_channel internal routine to make the
7650 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7652 * Changed silc_command_pending list to SilcDList. Also, added
7653 `ident' field to SilcServerCommandPending structure to identify
7654 the reply and to call correct callback.
7656 Added silc_server_command_pending_check function to replace the
7657 corresnponding macro. The silc_command_pending list is not
7660 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7661 to set identifier to previously allocated Command Payload. It
7662 is used to set identifier for command when resending Command
7665 * Added silc_command_payload_encode_payload to encode Command
7666 Payload buffer from SilcCommandPayload structure.
7668 * Added silc_argument_payload_encode_payload to encode Argument
7669 payload buffer from SilcArgumentPayload structure.
7671 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Changed WHOIS command to support router connection on server side.
7674 The whois request is always sent to router unless the server is
7675 standalone server. After server has received the reply from the
7676 router will it send the reply to the client.
7678 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7679 broadcast received broadcast packet. The function is used only
7680 by router. The broadcast packet is always sent to the router's
7683 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7684 render given ID to printable string, for log files for example.
7686 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7688 * Made basic router to router connections working. At least they
7689 can now connect to each other but nothing really works the way
7690 they are supposed - yet.
7692 * Added new initiator token to RouterConnection configuration
7693 file in silcd/serverconfig.[ch]. It is used to tell whether we
7694 are the initiator to the remote router or whether we'll expect
7695 the other end to connect.
7697 * Moved registering of listener task to silc_server_init, hence
7698 the server starts listenning as soon as it is run, even if it
7699 does not have connections to other routers. Let's see how well
7702 * Changed default connection retry timeouts for more suitable in
7705 * Removed cipher and such arguments from silc_idlist_add_client
7706 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7707 Added new function silc_idlist_add_data to add the keys and stuff
7710 * Added SilcIDListData structure and added it to SilcClientEntry
7711 and SilcServerEntry as their first field in the structure. This
7712 way we can explicitly cast the ID entries to the SilcIDListData
7713 structure and get common data for the entries. In past, we had
7714 to first check what type of connection it is and then cast it to
7715 correct ID entry type. Now, we can directly cast the opaque
7716 pointer to the SilcIDListData (no matter what ID entry it actually
7717 is) and get the data needed.
7719 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7722 in some circumstances even if threre were timeout tasks, though not
7723 IO tasks, but tasks anyway. Now fixed.
7725 * Defined SilcServerConnection structure to hold connection specific
7726 stuff about directly connected servers and routers. The definition
7727 is currently in silcd/server_internal.h. I thought about having
7728 a bit more important role fro this struct but for now it is used
7729 only when connecting to other server (or router actually).
7731 * Added connecting retry support in server when connecting to
7732 router(s). The retry feature implement exponential backoff
7733 algorithm. Also, added SilcServerParams structure to hold default
7734 parameters for server. For now, it include these retry settings
7735 and are hard coded. After server is moded to be as Silc Server
7736 Library this structure will be more important.
7738 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Changed client librarys channel->clients table to SilcList and
7741 changed code accordingly.
7743 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Changed client's channel table to SilcList and changed code
7746 accordingly. Also changed SilcChannelClientEntry to include back-
7747 pointer to the channel so that client entry can use that structure
7748 as list as well and we have fast cross-reference to the channel.
7749 This change dramatically decreased the complexity of channel
7750 handling with client entry and vice versa (removed one extra
7751 loop when searching for channel entry from many functions).
7753 * Changed server->sim from table to SilcDList and changed code
7756 * NAMES command can now be used from user interface. It will show
7757 the user list on the channel, neatly.
7759 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7760 Code now saves realname of the user if it becomes available.
7762 * Renamed configure.in to configure.in.pre and made ./prepare
7763 script to automatically add correct version string to
7764 configure.in which it creates from configure.in.pre.
7766 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7768 * NAMES command reply now shows users mode with the nickname when
7771 * Moved silc_client_ch[u]mode[_char] functions from
7772 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7773 place sucks, they are utility functions and should be in some
7776 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7778 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7781 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Added TRQ (efficient deque and list library) into lib/trq. This is
7786 a very good list library that is currently used in the SILC. Defined
7787 SilcList API over the library because I didn't like the API very
7788 much. See lib/trq/silclist.h for the API and examples of how to
7789 use the API. Fixed various places in the code to use the new
7790 SilcList API. The SilcList is meant for lists that has a structure
7791 already defined as a list. It is not suitable to add just some
7792 context to the list (in TRQ, the context is the list actually).
7794 So, I defined SilcDList that can be used for the purpose where
7795 predefined list structure does not exit. This can be used as
7796 such list. Now some context just can be added to the SilcDList.
7797 Currently this list is not used in the SILC just yet, though there
7798 are a lot places where this can replace dynamically allocated
7799 tables and I will fix these places, later, to use SilcDList.
7800 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7801 and use TRQ internally).
7803 Also fixed some annoying warning messages that the original TRQ
7804 code generated. Also minor changes to TRQ's Makefile.in.
7806 * Added support for querying by Client ID to both WHOIS and
7807 IDENTIFY commands into server, as required by the protocol.
7809 * Removed method function pointers from SilcBuffer structure. They
7810 weren't used to anything and just increased the context size for
7811 no good reason. This change also made silc_buffer_alloc and
7812 silc_buffer_free functions inline functions.
7814 * Disabled command flooding detection support until it's fixed so
7815 that it accepts commands in but does not execute them more than once
7818 * Added silc_net_localhost(), to return local hostname, into
7819 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7820 that must be initialized before calling silc_client_init.
7822 * Added new function: silc_server_send_notify_on_channels to send
7823 notify messages to all channels client has joined. It is assured
7824 that the message is sent only once per client.
7826 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7827 lib/silcutil/silcutil.[ch] as silc_format function. The new
7828 function is generic and is used by server as well, not only by
7829 the logging routines.
7831 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7832 the provided version string was not acceptable. Added new function:
7833 silc_ske_check_version into lib/silcske/silcske.h. The function
7834 must be implemented by the application (client or server) and it
7835 does not reside in the SKE library. The function checks the version
7836 string remote end sent.
7838 * Added back pointers (to opaque context and to SilcSocketConnection)
7839 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7841 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7842 duplicate packet context structure.
7844 * Changed `notify' client operation to send same arguments as client
7845 receives from server except for ID's. ID's are mapped to correct
7846 ID entry and that is returned. Also, if channel entry is not sent
7847 by server but the notify is for channel the channel entry is sent
7848 to application (otherwise application doesn't know that it is for
7849 channel (library gets it from packet's Destination ID)).
7851 * Added silc_client_remove_from_channels into client library to
7852 remove a client from all channels it has joined to. Used when
7853 received SIGNOFF notify from server. Added also new function
7854 silc_client_replace_from_channels to replace old ID entry with
7855 new ID entry on all channels. Used when received NICK_CHANGE
7858 * Fixed ID Cache list handling in silc_idlist_get_client in
7859 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7860 to get (or query) client by ID.
7862 * Updated TODO list.
7864 * Added connection authentication status message defined by the
7865 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7866 support for these into the code in client and server side.
7868 * Added generic function silc_client_send_command to send any command
7869 with variable argument list. Application should use this function
7870 to send commands if the command functions provided by the library
7871 does not suite for the application's user interface needs.
7873 * Added new `failure' client operation. Application is notified about
7874 received failure packet if client is executing a protocol. In this
7875 case the protocol's execution has failed.
7877 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7878 is required by the protocol.
7880 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7881 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7884 * Added status flag to SilcSKE object to indicate realtime status
7885 of the SKE protocol.
7887 * Application receives now exactly same command reply arguments as
7888 the library receives from server. However, if ID is received the
7889 corresponding ID entry is returned to the application (eg. Client
7890 ID is mapped to correct SilcClientEntry entry and that is returned).
7891 Changed command_reply client operation due to this change.
7893 * Changed all ID's in commands and in command replys as ID Payloads.
7894 Change affected both client and server side codes.
7896 All ID's sent in SILC network (with execption of ID's in SILC
7897 Packet header) are sent in ID Payload to support variable length
7900 * Server now notifies nick changes and notifies all clients on
7901 the channels about the new nickname (about the new Client ID,
7904 * Implemented CMODE command to change channel modes. Supports all
7905 channel modes defined by the protocol specs except ban and invite
7906 lists. (Also, private channel key mode is supported but support for
7907 setting private channel key in client is missing, thus, this mode
7908 has no effect on client side (except that server requires that the
7909 client uses private channel key and normal channel traffic does not
7912 Also, invite mode works per se, but INVITE command does not work
7913 yet correctly, so you can set channel as invite only channel but
7914 inviting clients to the channel does not work (it is yet to be
7915 thought what's the best way to do it).
7917 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7918 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7919 Implemented CUMODE command to change user's mode on the channel.
7920 Supports all modes defined by the protocol specs.
7922 * Added NAMES command reply to return users modes on the channel.
7924 * Removed unnecessary and slow ciphers from lib/silccrypt.
7926 * Set SO_KEEPALIVE option to connection sockets by default.
7928 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7930 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7931 redefined the Notify Payload into protocol specs.
7933 * Added silc_id_payload_parse_id to get ID directly from raw
7936 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7939 accept searching by Client ID as well.
7941 * Added support for LEAVE and SIGNOFF notify types in client library.
7943 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7944 to parse ID Payload from raw data.
7946 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7948 * Added flags parameter into silc_ske_assemble_security_properties
7949 function in lib/silcske/silcske.[ch].
7951 * Changed notify client operation to fit better for notify messages
7952 sent by server. The notify payload received from server is now
7953 passed to the application (after parsing it to SilcNotifyPayload).
7954 It is application's responsibility to retrieve the arguments
7955 from the payload and show the message the way it wants. The message
7956 sent by server is implementation specific.
7958 * Changed public keys to comply with the protocol specification.
7959 Old public keys are not supported anymore and are not compatible.
7961 * Removed nickname from Channel Payload as the latest draft removed
7962 it. The client must resolve the nickname from the NAMES command
7963 reply received when it joined the channel.
7965 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7967 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7969 * Fixed some errors in protocol specification drafts.
7971 * Created lib/silccore/silcnotify.c to implement Notify Payload
7972 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7973 generic payloads described by protocol specifications. The file
7974 includes implementations for ID Payload and Argument Payload.
7976 * Changed Command Payload implementation to use the new Argument
7977 Payload. Changed command_xxxx_payload to command_payload_xxxx
7978 to comply with SILC coding conventions.
7980 * Added suppport for Argument Payload handling in Notify Payload
7981 implementation as protocol requires it. Added the new support
7982 into server and client lib as well.
7984 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7986 * Added support for multiple nicknames on same channel. [n] is
7987 added locally to the nickname if there are more than one same
7988 nicknames on the channel.
7990 * Server now sends all nicknames that matched WHOIS request.
7991 Client also shows the list received from server.
7993 * Added TOPIC command to client side. User can now set and show
7994 current topic on channel.
7996 * Added MOTD command to client and server. Also, server sends the
7997 motd when client connects to the server.
7999 * Changed version strings to comply ISO 8601.
8001 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8003 * Fixed protocol error handling in client library. It should now
8004 cope even if the SKE fails for some reason.
8006 * Made new protocol specification drafts for submitting to IETF.
8008 * Implemented TOPIC command to server in silcd/command.c.
8010 * Added two new notify types into lib/silccore/silcnotify.h:
8011 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8012 notify nickname change and topic setting/change on a channel.
8014 * API change of command_reply operation in client library. The
8015 application gets now the status type received from server as well.
8017 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8021 * Cras fixed and optimized the packet handling even further and
8022 it should work now. Minor change to the prototype of function
8023 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8025 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8027 * Added new function into lib/silcutil/silcschedule.[ch]:
8028 silc_schedule_with_fd to select() a specified fd. The function
8029 returns after timeout expires or data arrives or goes. The
8030 function is used by packet routines to wait that all data is
8031 received from network.
8033 * Fixed data reading from network in lib/silccore/silcpacket.c.
8034 The code now assures that all data is read from the fd and then
8035 continues packet processing. This was a bug fix since the code
8036 used to drop some data in some circumstances.
8038 * Added new function into lib/silcclient/client.[ch]:
8039 silc_client_start_key_exchange to start key exchange after
8040 connection has been established to server. The code internally
8041 now uses this funtion but its main purpose was to provide it
8042 for applications that perform their own connecting. After
8043 application has created a connection it merely calls this
8044 function to start the key exchange between client and server.
8045 The library takes care of everything else after that.
8047 Updated also lib/silcclient/README to explain the usage of
8050 * Do not send to application information that connection has
8051 been established. Application gets notified it by connect
8054 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8056 * Applied cras's patch to add silc_schedule_one function. The
8057 function runs scheduler once and returns.
8059 * Fixed the scheduler after cras messed it up. The timeout
8060 handling works now as it's supposed to work.
8062 * Added into lib/silccore/ silcnotify.h to include notify
8063 message types support. Changed silc_server_send_notify*
8064 functions, in server.[ch], to support those new notify types.
8065 Added the support for the notify types into client library,
8066 as well. Added new notify client operation into ops.h in
8069 * Changed silc_server_packet_send_to_channel to send normal
8070 packets instead of just channel message packets. The function
8071 is now used to send the notify packets to channels. It is not
8072 used to send channel message packets anymore, as server never
8075 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8076 va_arg()s as it seems to require it nowadays. I guess, if SILC
8077 is compiled with older va_arg() the new code should work anyway.
8079 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8081 * Splitted core library. Core library (lib/silccore) includes
8082 now only SILC protocol specific core (and common) components.
8083 Created new utility library (lib/silcutil) that includes more
8084 generic purpose stuff. The stuff for util library was taken
8085 from the old core library. This was minor and easy split.
8087 * Created SILC Client Library (lib/silcclient) that includes
8088 implementation of the SILC client without user interface. This
8089 was major move from silc/ directory. The code has been changed
8090 so that it is transparent towards the user interface. The
8091 silc/ directory includes now the same user interface as before
8092 and it uses the new client library. Read lib/silcclient/README.
8093 Basicly, the client library performs everything else related
8094 to SILC except user interface handling. Also, configuration
8095 files are considered to be part of user interface and library
8096 does not handle them.
8098 This change also changed a lot of structures, function naming etc.
8099 Most important change was that SilcClientWindow object was
8100 renamed to SilcClientConnection in the client library. Created
8101 also new file lib/silcclient/ops.h. Also added new files
8102 silc/local_command.[ch] and silc/client_ops.[ch].
8104 All these changes were made to make it easier for user interface
8105 designers to create what ever user interface for the SILC client
8108 It is also expected that the server will be moved to lib
8109 directory as well and SILC Server Library will be created;
8110 sometimes in the future.
8112 * Removed Local commands from lib/silccore/silccommand.h as
8113 they are application specific and new client library does not
8114 handle any of those anymore.
8116 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8117 old client implementation in silc/.
8119 * Added support for callback functions in SILC_LOG_* macros.
8120 Application can now set its own callbacks that will be called
8121 instead of using the default functions that will always print
8122 the debug messages to stderr (or stdout). Also, debugging can
8123 now be disabled by setting silc_debug to FALSE and re-enabled by
8124 setting it to TRUE. Note, that logging will still work even
8125 if debugging is disabled.
8127 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8128 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8129 silc_log_reset_debug_callbacks.
8131 * To enable debugging in silc client one must give now -d
8132 option on command line.
8134 * Changed silc_schedule_init to automatically allocate task queues
8135 if they are not allocated before calling it.
8137 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8139 * Added GMP 3.1 into math library.
8141 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8143 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8144 a channel in SILC network. The packet is used by servers and
8145 routers to notify other routers that user has left a channel.
8146 This little feature was missing until now. Added the feature
8147 to protocol specification as well.
8149 Added functions: silc_server_send_remove_channel_user and
8150 silc_server_remove_channel_user into server.[ch].
8152 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8153 lib/silccore/silcpacket.h. However, they are not implemented
8156 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Fixed joining to a channel and sending channel messages
8159 between server and router. The channel message sending should
8160 now work inside a cell.
8162 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8164 * Fixed the private message sending between server and router.
8165 The private message sending should now work inside a cell.
8167 * Added silc_server_replace_id into server.[ch] to replace
8168 existing ID in the SILC network.
8170 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8171 and silc_idlist_replace_server_id into idlist.[ch] in server.
8173 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8175 * Fixed the server to server connections. Server can again now
8176 connect to router. Router to router connections probably does
8179 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8181 * Added dynamic protocol registering support. Now protocols can
8182 registered and unregistered on the fly. Patch by cras.
8184 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8186 * Added lib/contrib directory to hold routines that some platforms
8187 don't have but are needed by SILC.
8189 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8190 into lin/contrib to provide getopt() and getopt_long() for
8191 those who don't have it.
8193 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8195 * Added AWAY command to client. When away message is set and
8196 client receives a private message packet the client automatically
8197 replies to the sender with the away message.
8199 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8200 bug seemed to be the cause of recent problems when compiling
8203 * Added version detection support to SKE protocol specification
8204 and added the new changes to the SKE implementation as well.
8205 There were other minor changes in the SKE protocol as well.
8207 Many changes in lib/silcske/silcske.[ch] and in
8208 lib/silcske/payload.[ch].
8210 * Added ^U functionality, clear input line. Patch from cras.
8212 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8214 * Mainly small bugfixes on core library. Fixed some debugging
8215 logging and buffer overflow in silclog.c.
8217 * Updated config.sub and config.guess on the distribution tree.
8219 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Added command lagging support in server. Client may execute
8222 commands now only once in two seconds.
8224 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8226 * Optimized packet reception. MAC computation and checking is now
8227 also more optimized. A lot previously duplicated code is now
8228 used as generic by both client and server.
8230 * Fixed key pair generation in clientutil.c
8232 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Added into lib/silccore/silcbufutil.[ch] new function;
8235 silc_buffer_realloc.
8237 * Moved generic packet sending/encryption functions to
8238 lib/silccore/silcpacket.[ch] from client and server. Some
8239 rewriting of the functions.
8241 * Moved all generic packet reception/decryption functions to
8242 lib/silccore/silcpacket.[ch] from client and server. The
8243 packet processing is now much cleaner in both client and server.
8244 These were major changes in both client and server.
8246 * Created many common functions in server to do packet sending.
8247 Previously code were duplicated a lot, this has been removed
8250 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8252 * Rewrote major parts of the ID cache system. Don't know
8253 whether it is better now or not but at least the API is more
8256 * Major rewrite on ID cache stuff on client because of the ID
8257 cache API changes. Added idlist.c to client.
8259 * Also major rewrite on ID cache stuff on server as well.
8260 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8261 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8262 in hand, instead they are all put into the ID cache system now.
8263 All server_idlist_* routines uses ID cache now instead of
8264 traversing its own lists (those lists does not exist anymore).
8265 SilcIDList though still exists. Also, SilcXXXEntry's are
8268 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8270 * Finally made the SKE implementation compliant to the protocol
8271 specification. All mp integers are now binary encoded as
8272 opposed being HEX encoded.
8274 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8277 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8278 functions: silc_[encode/decode]_pem. Also added function
8279 silc_encode_pem_file to PEM encode with newlines ('\n') for
8282 * SILC public keys are now encoded either PEM or binary. Same
8283 option is for private keys as well. By default private keys
8284 are binary encoded and public keys PEM encoded. Silly HEX
8285 encoding were removed.
8287 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8288 function to create fingerprints.
8290 * Fixed a bug in SHA1; does not change the original data anymore.
8292 * Partly implemented INFO command on client and server side.
8293 Fixed CLEAR command. Changes to SERVER command; show current
8294 server(s) when giving command without arguments. Added
8295 VERSION command to client.
8297 * Added check to server that unregistered connections cannot
8298 execute commands (unless it is specificly allowed).
8300 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8302 * Fixed screen refresh.
8304 * Fixed channel joining bug from client. On some circumstances
8305 client tried to join to a channel it had already joined.
8307 * Added public key verification process into client's protocol.c.
8308 The client now verifies the public key from user and saves
8309 it into ~./silc/serverkeys/ directory.
8311 Added into: clientutil.[ch]: silc_client_verify_server_key.
8313 * Changed SKE protocol's silc_ske_initiator_finish function
8314 to accept callback function that verifies the received public
8315 key. Removed old silc_ske_verify_public_key function.
8317 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8319 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8320 silc_pkcs_private_key[_data]_set.
8322 * Made the password and public authentication more cleaner in
8323 server's protocol.c.
8325 * Removed historic and obsolete protocol `channel_auth' from
8326 both client and server.
8328 * Removed wrong way of sending command status messages from
8329 server to client in server's command.c. The old way violated
8330 protocol specification.
8332 Changes to silccore/silccommand.[ch]: removed
8333 silc_command_encode_status_payload -> not needed anymore,
8334 changed silc_command_encode_payload_va to accept extra
8335 argument on variable argument list. The argument type must
8336 now be provided to the function. Also, added new function:
8337 silc_command_encode_reply_payload_va which is same as
8338 normal command_encode_payload_va except command status type
8339 is provided as extra argument.
8341 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8343 * Added ~./silc directory handling. The directory includes the
8344 public and private keys for the client.
8346 Added silc_client_check_silc_dir, silc_client_create_identifier
8347 and silc_client_load_keys.
8349 * Implemented SILC protocol compliant public key. Added public
8350 and private key saving to and loading from files.
8352 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8353 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8354 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8355 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8356 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8358 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8359 silc_pkcs_load_[public/private]_key.
8361 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8363 * Added silc_server_get_route (route.[ch]) to get connection
8364 data for the fastest route for given ID.
8366 * Implemented INVITE command on client and server. The command
8367 were re-defined in the SILC Protocol Specification and the
8368 implementation now complies with the specification.
8370 * Implemented PING command on client and server.
8372 * Implemented NAMES command on client and server. The server side
8373 supports currently only normal server not router server yet.
8374 Some changes to NAMES definition in SILC protocol specification.
8376 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Implemented LEAVE command on client and server.
8380 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8381 again. This change was made to the protocol as well. Server
8382 should not violate the protocol specification anymore.
8384 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8386 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8387 was tested. SOCKS4 was not but should work anyway.
