518 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
519 commands that was missing it, and updated protocol specs and
520 the server implementation. Protocol TODO #10. The affected
521 file is silcd/command.c.
523 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
524 generic reply to a generic request (REQUEST flag), and
525 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
526 way. A draft-riikonen-silc-flags-payloads-00.txt is written
527 to define the payload for DATA flag. Added the flags to
528 the implementation. Protocol TODO #9. Affected file is
529 lib/silccore/silcchannel.h.
531 Changed the client library to return the message length
532 to application as well in the channel_message and private_message
533 client operations. Affected files are
534 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
535 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
536 and lib/silcclient/client_ops_example.c.
538 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
539 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
540 the channel. Updated protocol specs and impelemented this
541 to client and server. Protocol TODO #6. Affected files are
542 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
543 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
545 Added new options m and M to CMODE command in Irssi SILC
546 client to set these modes.
548 * Deprecated all administrative commands from SILC protocol
549 since they are highly implementation specific commands.
550 Updated protocol specs. Moved the old commands in
551 implementations to private range of command types. Affected
552 files are silcd/command.c, lib/silcclient/command.c and
553 lib/silcclient/command_reply.c. Protocol TODO #8.
555 * Fixed a bug in server where sending unknown command crashes
556 the server. Affected file silcd/command.c.
558 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
560 * Added SILC_PROTOCOLVERSION macro to check protocol version
561 of a socket connection. The affected file is
562 lib/silcutil/silcsockconn.h.
564 * Added better error logging in rekey protocol. Affected file
567 * Do not check public key types in SKE during rekey. Affected
568 file lib/silcske/payload.c.
570 * Fixed the rekey protocol with PFS, which was totally broken.
571 Affected file silcd/protocol.c.
573 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Some client implementations quit network by doing first LEAVE
576 and then immediately SIGNOFF (like Bombyx). We now do check
577 after a short time after LEAVE notify and check whether the
578 client is still valid after LEAVE, and if not we remove it from
579 cache. Affected file is lib/silcclient/client_notify.c.
581 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
583 * Merged version 1.1.4 of zlib. Even if it not currently in use,
584 it's good not to have security holes here.
586 * Fixed a negative refcount situtuation for the config context.
587 Affected file is silcd/serverconfig.c.
589 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
591 * ROBOdoc documented lib/silcutil/silcutil.h.
593 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
595 * Optimized even more the SilcPacketContext structure. Now
596 totally saved 16 bytes of memory per context after optimization.
597 Affected files are lib/silccore/silcpacket.[ch].
599 * Made strict checks for valid SILC IDs. Affected file is
600 lib/silccore/silcid.c.
602 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Changed the object argument for silc_cipher_register,
605 silc_hash_register, silc_hmac_register and silc_pkcs_register
606 to const. Affected files are lib/silccrypt/silccipher.[ch],
607 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
609 * Changed the silc_get_username and silc_get_real_name to
610 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
612 * Fixed the Irssi SILC Client to use the silc_get_username and
613 silc_get_real_name insted of glib routines since the glib
614 routines only corrupt stack. Fixes the Irssi SILC to work in
615 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
617 * Fixed the Irssi to not use g_get_home_dir since it crashes
618 or returns garbage on cygwin and corrupts stack. Added function
619 get_home_dir to Irssi routines. Affected files are
620 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
622 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
624 * Made some structure optimizations. SFTP memory FS MemFSEntry
625 entry structure. Optimized SilcTask structure. Optimized
626 SilcPacketContext structure.
628 Affected files lib/silcsftp/sftp_fs_memory.c,
629 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
631 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * And yet again reverted back the config thing since Johnny
634 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
637 * Fixed memory leaks from config object. Affected files are
638 silcd/serverconfig.[ch].
640 * Added support for adding new connections to the server in rehash.
641 After rehash they take effect.
643 Added support for changing the maximum allowed connections in
644 rehash. The number can grow but going smaller is not supported.
646 Added function silc_server_num_sockets_by_remote to the
647 silcd/server_util.[ch].
649 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
651 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
653 * Added preliminary checking during config parsing for a valid
654 public/private key and removed further checks in the code.
655 Affected files are silcd/serverconfig.[ch], server.c.
657 * Moved functions silc_server_drop() and silc_server_daemonise()
658 from server.c to silcd.c since they are stricly related to
659 the application activity.
661 * Reverted a small part of the automatic ref/unref since
662 it caused a double unref in some situations. Affected
663 files are silcd/silcd.[ch], server.c, serverconfig.c.
665 * Added some .cvsignore files in the lib directory.
667 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
669 * Fixed silc_net_gethostbyaddr to correctly resolve by
670 address. Affected file lib/silcutil/silcnet.c.
672 * Fixed the notify relaying to client. The HMAC to be used
673 with relayed packets ws wrong and caused decryption failure
674 at the client end. Affected file is silcd/packet_receive.c.
676 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
678 * Created new branch silc_protocol_1_0_branch.
680 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
682 * Changed the silc_server_config_* routines to be SilcServer
683 independent. They are now officially application specific code
684 and not part of generic server implementation. Affected files
685 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
687 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
689 * Added automatic referencing of config context in the
690 silc_server_config_alloc, and automatic unreferencing in the
691 silc_server_config_destroy. Affected files are
692 silcd/serverconfig.[ch], silcd/silcd.c.
694 * Fixed the silc_log_quick handling in the logging routines.
695 It didn't log quickly when it was TRUE. Affected file is
696 lib/silcutil/silclog.c. Also the flush delay was set even
697 if it was 0 in config file. Affected file is
698 silcd/serverconfig.c.
700 * Added support for changing key pair of the server in rehash.
701 Affected file silcd/server.c.
703 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
705 * Fixed the TOPIC_SET notify to not cras. It changed the topic
706 too early, before getting the channel entry. Affected file
707 is silcd/packet_receive.c.
709 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
711 * Added functions silc_server_config_[ref/unref], these are used
712 to prevent that the config object is destroyed.
714 No longer directly affect global variables silc_log_quick and
715 silc_log_delay, they are first cached inside the config object
716 and then applied with silc_server_config_setlogfiles().
718 silc_server_config_set_defaults() is now internal to
719 serverconfig.c, there are no reasons to show this internal stuff
722 Affected files are silcd/serverconfig.[ch].
724 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
725 fprintf's to stderr, since some code may be executed again after
726 the server went into the background. Affected files are
729 * Added rehash support. Added function silc_server_rehash() that
730 will perform all the basic tasks of the rehashing procedure.
732 * Added command line option `-x, --hexdump'. This will enable the
733 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
734 The option `--hexdump' implies `--debug'.
736 * Fixed a bad bug in the logging APIs (silcutil library) where
737 the application would crash after calling silc_log_reset_all().
739 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Fixed the KICKED notify handling in client library to
742 correctly remove the channel and all entries from the
743 channel when I was kicked. This bug crashed the client.
745 Fixed yet another but in KICKED notify handling to remove
746 the kicked client correctly from the channel.
748 Affected file is lib/silcclient/client_notify.c.
750 * Fixed a minor bug in looking up correct client entry
751 in KICKED notify in server. Affected file is
752 silcd/packet_receive.c.
754 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
755 sources correctly to distribution. Fixes --with-gmp option.
757 * Removed the manual rehashing from ID Cache, and changed it
758 to use the SILC Hash Table's auto rehash feature. Affected
759 file is lib/silccore/silcidcache.c.
761 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Fixed a bug in the silc_client_nickname_format function that
764 handles the multiple same nickname formatting. Two clients
765 with same nickname caused problems after the first one left
766 and rejoined. It didn't format the nickname correctly.
767 Affected file is lib/silcclient/idlist.c.
769 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
771 * Don't change the topic if olod topic is same as new one.
772 Affected file is silcd/packet_receive.c.
774 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
776 * Added cross-reference support to the SILC Documentation
777 generator. All types across all HTML files are now cross-
778 referenced. Affected files util/robodoc/generator.c and
779 scripts/silcdoc/silcdoc.
781 * Added file lib/silcutil/silctypes.h to include all the
782 arithmetic type definitions and some macros. Removed
783 includes/bitmove.h and moved macros to silctypes.h.
785 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
787 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
789 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
791 * Added `type' argument to silc_id_payload_parse_id function which
792 now returns the type of the ID to the sent pointer. Affected
793 file is lib/silccore/silcid.[ch].
795 * Added check for CMODE_CHANGE notify type that mode change is
796 allowed by the sender. Affected file silcd/packet_receive.c.
798 * Added check for CUMODE_CHANGE notify type that mode change is
799 allowed by the sender. Affected file silcd/packet_receive.c.
800 Added the ID type as CUMODE_CHANGE notify type as argument
801 to the `notify' client operation. Affected files are
802 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
804 * Added function silc_client_add_server to the client library.
805 Added support for resolving also channel and server info when
806 received unknown entity in notify packet. Affected files are
807 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
809 * Added function silc_command_get_status to return the command
810 status from the command reply's argument payload. Affected files
811 are lib/silccore/silccommand.[ch].
813 * Added check for KICKED notify type that the kicking is
814 allowed by the client. Affected file silcd/packet_receive.c.
816 * Created function silc_get_input which can be used to get input
817 (echo on or off) from user on command line. Affected files are
818 lib/silcutil/silcutil.[ch].
820 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
822 * Optimized silc_server_packet_relay_to_channel function.
823 Added new function silc_channel_message_payload_encrypt which
824 can be called directly if channel message payload needs to
825 be encrypted and is already encoded (no need to call _encode
826 function). Packet relaying is now done by router without any
827 extra memory allocations. Affected files are
828 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
831 * Fixed the INVITE notify handling. It took wrong arguments
832 as invite list and invite delete. Affected file is
833 silcd/packet_receive.c.
835 * Added check for TOPIC_SET notify type that the topic change is
836 allowed by the client. Affected file silcd/packet_receive.c.
838 * Added check for INVITE notify type that inviting is allowed by
839 the client. Affected file silcd/packet_receive.c.
841 * Changed the silc_server_client_on_channel to return the
842 SilcChannelClientEntry as well. Moved the function
843 silc_server_check_cmode_rights to server_util.[ch].
844 Affected files are silcd/server_util.[ch], silcd/command.c.
846 * Added function silc_server_check_umode_rights to check whether
847 changing client's user mode is allowed. Added check for
848 UMODE_CHANGE notify type that the umode change is allowed
849 by the client. Affected files are silcd/server_util.[ch],
850 silcd/packet_receive.c and silcd/command.c.
852 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
854 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
855 ID length. It ignored that ID can be IPv6 based as well.
856 Affected file lib/silccore/silcpacket.h.
858 * Fixed the silc_id_id2str and silc_id_str2id to take the
859 IPv6 address offset's into consideration. Affecte file is
860 lib/silccore/silcid.c.
862 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
864 * Fixed the internal Unix scheduler functions to check for
865 NULL context they may receive. The affected file is
866 lib/silcutil/unix/silcunixschedule.c.
868 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
870 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
871 can specify different directory with --home command line
872 parameter. Affected files irssi/src/silc/core/client_ops.c,
875 * SILC-specific commands aren't now executed if the active server
876 isn't of SILC-type, so there won't be problems with having
877 IRC and SILC protocol support in same client. Affected files
878 irssi/src/silc/core/silc-channels.c, silc-servers.c,
881 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
883 * Improved the signal support in SILC Schedule. Added new
884 function silc_schedule_signal_call which is used by application
885 to mark a signal to be called. It is now safe to perform
886 any kind of tasks in signal callbacks since it is guaranteed
887 that the application specified signal callback is called
888 after the signal is over. Affected files are
889 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
891 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
893 * Added `name' field to SilcChannelPrivateKey to represent
894 application given name for the key. Moved also the context from
895 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
896 Added the `name' argument also to the function
897 silc_client_add_channel_private_key.
899 Added function silc_client_current_channel_private_key to set the
900 current channel private key in use.
902 Added "change" command to KEY command which can be used to change
903 the current channel private key. Bound the command also to
906 Also affected files lib/silcclient/client_channel.c,
907 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
909 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
911 * Added silc_rng_get_byte_fast function in to the
912 lib/silccrypt/silcrng.[ch].
914 * Changed the interface of silc_packet_assemble and the
915 silc_packet_send_prepare. If silc_packet_assmble is now
916 called the application does not call silc_packet_send_prepare
917 because the library will call it automatically. These
918 interfaces now also return a reference to the outgoing buffer
919 which includes the assembled packet, which the application can
920 use to encrypt the packet.
922 Affected files are lib/silccore/silcpacket.[ch],
923 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
924 silcd/packet_send.c, server_backup.c and packet_receive.c.
926 * Fixed a packet sending bug on very high load, where outgoing
927 packet queue wasn't handled correctly and packets got corrupted.
928 Affected files are lib/silcutil/*/silc*sockconn.c,
929 lib/silcclient/client.c and silcd/server.c.
931 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
933 * Added macro SILC_PACKET_DATALEN which can be used during
934 packet assembling to check whether the data to be added to
935 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
936 len is truncated until it fits it.
938 Added checks for maximum length of channel message payload and
939 private message payload also.
941 Added checks for maximum packet length in server and in
944 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
945 lib/silcclient/client.c, lib/silccore/silcchannel.c and
946 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
947 lib/silcclient/client_prvmsg.c.
949 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
951 * Added silc_server_packet_queue_purge call to the
952 silc_server_disconnect_remote to assure that all data in the
953 queue before disconnecting is sent to the network. Affected
956 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
958 * Added the deleting of server's own ID cache entry to the
959 silc_server_free function. Free also everything else that
960 has been allocated in silc_server_init. The affected file
963 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
965 * Added functions silc_parse_version_string, silc_version_to_num,
966 and silc_ske_parse_version to parse SILC protocol style version
967 strings. Affected files lib/silcutil/silcutil.[ch] and
968 lib/silcske/silcske.[ch].
970 * Added new configuration params: version_protocol, version_software
971 and version_software_vendor to specify what version the remote
972 host must at least be to be able to connect to server. The vendor
973 string can be regex matched too. Added new function
974 silc_server_connection_allowed to check maximum number of allowed
975 connections, and allowed versions for incoming connections.
976 Affected files are silcd/server.c, server_util.[ch] and
979 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
981 * Added preliminary support for signals in scheduler. The
982 signals we care about are now blocked always when the scheduler
983 is locked. This way we can synchronise the use of signal with
984 scheduler. It is guaranteed that when signal occurs the scheduler
985 is not locked, and thus new tasks can be safely added to the
988 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
989 to silc_schedule_internal_init and silc_schedule_internal_uninit.
990 Added new platform specific routines
991 silc_schedule_internal_signals_[un]block and
992 silc_schedule_internal_signal_[un]register.
994 Added new functions to SILC Schedule API:
995 silc_schedule_signal_[un]register. Each signal that application
996 is going to use should be registered to the scheduler.
998 Affected files are lib/silcutil/silcschedule.[ch],
999 lib/silcutil/*/silc*schedule.c.
1001 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1003 * Check for unauthenticated client and server in the
1004 silc_server_new_client and silc_server_new_server functions.
1005 Affected file silcd/packet_receive.c.
1007 * Added function silc_string_is_ascii to check whether given
1008 string is 7-bit ASCII string. Affected files are
1009 lib/silcutil/silcutil.[ch].
1011 * Added function silc_id_is_valid_server_id into the
1012 silcd/serverid.c and added checking for valid Server ID's in
1013 silc_server_new_server. The Server ID must always be based
1014 on the server's public IP address.
1016 * Added logging of DISCONNECT packet message in the server.
1017 Affected file silcd/server.c.
1019 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Changed all library interfaces that use Global RNG to also
1022 accept SilcRng as argument. Affected files are
1023 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1024 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1025 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1026 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1027 lib/silccrypt/rsa.c.
1029 * Added function silc_pkcs_generate_key to the
1030 lib/silccrypt/silcpkcs.[ch] for applications so that they
1031 don't need to do pkcs->pkcs->init calls anymore.
1033 * Remove SilcSocketConnection from the SFTP API since it really
1034 wasn't needed there. The application has the information
1035 saved in its contexts anyway and the SFTP layer doesn't need
1036 know about it. Affected files lib/silcsft/silcsftp.h and
1037 lib/silcsftp/sftp_[server/client].c.
1039 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].

1047 algorithm list on EPOC. Affected files are
1048 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1051 * Fixed the handling of third parameter of KICKED notify, since
1052 it was mistakenly updated to SILC Protocol 1.0 even though it
1053 is to be included in 1.1. Since it is not in 1.0 it is not
1054 mandatory, and this fix now handles it only if it is provided,
1055 and it is not error if it is not provided. Affected file
1056 lib/silcclient/client_notify.c.
1058 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1093 functions to be used with SilcHashTable. They can be used to
1094 hash public keys and compare public keys in hash table. Affected
1095 file lib/silcutil/silcutil.[ch].
1097 * Added support for specifying multiple public keys for Client
1098 connection section in server configuration file. This makes it
1099 possible to accept multiple public keys from same host, or to
1100 make a section that accepts any incoming host, and have the
1101 accepted public keys listed in the section.
1103 Added functions silc_sever_[find/get]_public_key, added the
1104 support for this actually to all connection sections but only
1105 the Client section is currently allowed to specify multiple
1108 Affected files are silcd/server.c, server_internal.h,
1109 command.c, protocol.c, server_util.[ch], packet_receive.c.

1123 Affected files are lib/silcutil/silclog.[ch].
1125 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Fixed the server to check correctly the amount of connections
1128 from single host, by checking also the type of the connection.
1129 Fixed also the comparison of number of connections and number
1130 of allowed connections. Affected files are silcd/server.c,
1133 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1136 channel as well. Fixed JOIN command reply to check whether a
1137 client is on channel already and not join it twice. Affected
1138 file lib/silcclient/command_reply.c.
1140 * Added new file silc-expandos.c into irssi/silc/core/ to return
1141 various stuff for various signal for the statusbar etc. updating.
1142 Now Irssi SILC client prints channel user modes etc. on the

1212 application does not need to define them. Affected file
1213 includes/silcincludes.h.
1215 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1216 old name went against naming convention. Applications now
1217 include "silcclient.h" instead of "clientlibincludes.h".
1218 Removed includes/clientlibincludes.h, it is redundant now.
1220 * Renamed includes/version.h to silcversion.h.
1222 * Added really preliminary support for OS/2 into the util
1223 library. Only thread & mutex API is implemented, others
1224 are still to be implemented. Created the lib/silcutil/os2/
1225 directory. Created also file includes/silcos2.h.
1227 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1258 * Added `user_count' to the SilcChannelEntry which now tells the
1259 number of users on the channel. The user count is now saved
1260 in normal server of global channels as well. Affected files
1261 silcd/server.c, idlist.h, packet_receive.c and command.c.
1263 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1264 include file utility functions.
1266 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1267 instead of calling directly OS routines.
1269 * Fixed NICK change printing in Irssi SILC Client. Fixed
1270 KICKED notify printing in Irssi SILC Client. Affected file
1271 irssi/src/silc/core/client_ops.c.

1277 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1279 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1280 the SKE interface a bit.
1282 * Fixed padding problem in PKCS#1. The padding was not actually
1283 random since the random number generator was used incorrectly.
1284 This security bug affects only when encrypting with PKCS#1, and
1285 it is not currently used at all in SILC. SILC only use signing
1286 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1288 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1341 Affected files are silcd/serverconfig.[ch].
1343 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1345 * Fixed command line parameter handling. All SILC initialization
1346 is now done in silc_core_init() which also fixes autoconnecting
1349 Affected files irssi/src/silc/core/silc-core.c,
1350 irssi/src/fe-text/silc.c.
1352 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1354 * Added new configuration options and blocks:
1355 keepalive_secs, reconnect_count, reconnect_interval,
1356 reconnect_interval_max, reconnect_keep_trying and
1357 require_reverser_lookup. Added ConnectionParam block, and
1358 implemented the connection parameters when connecting as
1359 initiator and when accepting connections as responder.
1361 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1362 whether given configuration value has been given already.
1364 Affected files silcd/serverconfig.[c], server.[c].
1366 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1367 algorithm parts and created new file silcalgs.conf, that
1368 is now included from the example_silcd.conf.in.
1370 * Optimized the silc_server_connect_to_router_second to take
1371 the connection configuration object from the SilcServerConnection
1372 object instead of finding it during the connecting phase.
1373 Added the configuration object to SilcServerConnection struct.
1374 Affected files silcd/server_internal.h, server.c.
1376 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1378 * Add the client on channel after it was resolved at the
1379 channel message receiving, and it was not already on the
1380 channel. Affected file lib/silcclient/client_channel.c.
1382 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Fixed the public key authentication to allocate always the
1385 destination signature buffer instead of using static buffer.
1386 Affected file silcd/protocol.c.
1388 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1397 config file, allowing both public key and passphrase based
1398 authentication to be set at the same time.
1400 Added `prefer_passphrase_auth' setting in config file which
1401 can be used to set to prefer passwd auth if both passwd and
1402 public key is set. If not set, public key is preferred.
1403 This has effect only when being initiator (responder will try
1406 Added support for authentication with passphrase and public key
1407 at the same time. The passphrase is tried first always since
1408 it is faster to check.
1410 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1412 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1442 as header filenames.
1444 * Removed lib/silcclient/README and created HTML file
1445 lib/silcclient/silcclient_using.html, which is now included
1446 as part of Toolkit documentation.
1448 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1450 * Fixed CUMODE_CHANGE notify handling to change the mode of
1451 correct client. Affected file lib/silcclient/client_notify.c.
1453 * Make silc_rng_alloc fail if it cannot allocate the sha1
1454 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1456 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1458 * Fixed the file transfer's key agreement payload to include
1459 zero port also if the hostname is NULL because it could not
1462 Call file transfer monitor callback now also if error occurs
1463 during key agreement protocol.
1465 Changed the silc_client_file_send interface to return the
1466 SilcClientFileError instead of session id. The session ID
1467 is returned into pointer provided as argument.
1469 Check that the file exists locally before sending the
1470 file transfer request at all.
1472 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1474 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1479 is changed and +k mode is set in the channel. Affected file
1480 irssi/src/silc/core/silc-channels.c.
1482 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1483 SILC_LOG_WARNING to give out Warning and not Error. Affected
1484 file lib/silcutil/silclog.c.
1486 * Fixed the channel message payload decryption in the function
1487 silc_channel_message_payload_decrypt to not modify the original
1488 buffer before it is verified that the message decrypted
1489 correctly. Otherwise, next time it is called with correct
1490 channel key it won't encrypt since the payload is corrupted.
1491 Affected file lib/silccore/silcchannel.c.
1493 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1503 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed a bug in hash table internal routine for traversing
1506 the table with foreach callback. The current entry may
1507 become invalid in the callback but it was referenced after
1508 the callback returned.
1510 Do not allow auto rehashing of hash table during the
1511 silc_hash_table_foreach operation, for same reasons as it is
1512 not allowed for SilcHashTableList. Affected files are
1513 lib/silcutil/silchashtable.[ch].
1515 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1517 * Defined DLLAPI into silcincludes.h and silcwin32.h for

1521 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1523 * Fixed private message handling. It used some old code that
1524 caused the client to crash. Affecte file is
1525 lib/silcclient/client_prvmsg.c.
1527 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1529 * Added function silc_client_add_channel,
1530 silc_client_replace_channel_id, and removed functions
1531 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1532 from client library.
1534 * Added cross reference of the joined channels to the
1535 SilcClientEntry, and changed the SilcChannelEntry's
1536 users list to SilcHashTable. The affected files are
1537 lib/silcclient/idlist.[ch].
1539 * Fixed a bug in hash table tarversing. While the hash table
1540 is traversed with SilcHashTableList the table must not be
1541 rehashed. It is now guaranteed that auto rehashable tables
1542 are not rehashed while tarversing the list. Also defined that
1543 silc_hash_table_rehash must not be called while tarversing
1544 the table. Added function silc_hash_table_list_reset that must
1545 be called after the tarversing is over. The affected files are
1546 lib/silcutil/silchashtable.[ch].
1548 * Changed all hash table traversing to call the new
1549 silc_hash_table_list_reset in server and in client library.
1551 * Added function silc_client_on_channel to return the
1552 SilcChannelUser entry if the specified client entry is joined
1553 on the specified channel. This is exported to application as
1554 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1556 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1558 * Fixed founder regaining problem with JOIN command on normal
1559 server. The notify for mode change must be sent always and
1560 not only if !cmd->pending. Affected file silcd/command.c.
1562 * Fixed the WHOWAS command's reply sending to support the
1563 lists correctly. Affected file silcd/command.c.
1565 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1567 * When sending JOIN command to router for processing the
1568 sender's old command identifier was not saved back to the
1569 sender's command context, fixed now. The affected file is
1572 * Create the key in JOIN command of the router did not return
1573 the channel key, added check for this. Affected file is
1576 * Fixed a channel ID update bug in JOIN command reply. Do
1577 not directly upgrade the ID but call the function
1578 silc_idlist_replace_channel_id if the ID was changed.
1579 Affected file silcd/command_reply.c.
1581 * Fixed memory leaks from command calling if it would fail.
1582 Affected file silcd/command.c.
1584 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Applied patches from cras:
1588 Memory leak fixes around libaries, irssi window resize fix,
1589 new silclist.h and silcdlist.h, all extern inline changed to
1592 * Removed dotconf from lib/dotconf, not needed anymore.
1594 * Removed TRQ from lib/trq, not needed anymore.
1596 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1597 with server connections. Later this will be configurable
1598 in config file after new config file is done. Affected file
1601 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1603 * Fixed a crash in server related to channel announcements.
1604 Affected file silcd/server.c.
1606 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1608 * Fixed memory leaks in silc_server_create_new_channel*
1609 functions. Affected file silcd/server.c.
1611 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1612 which ID was changed. This way the router will send the
1613 user list for the channel again, and server won't be in
1614 desync in some rare circumstances. Affected file is
1615 silcd/packet_receive.c.
1617 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1619 * Check for NULL socket pointer in the function
1620 silc_server_packet_send_to_channel_real. Affected file
1621 silcd/packet_send.c.
1623 * Fixed the BAN notify handling to correctly remove ban
1624 list. Affected file silcd/packet_receive.c.
1626 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1628 * Fixed some header addition to Toolkit distribution in
1629 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1631 * Added lib/silcclient/client_ops_example.h as an template
1632 file for application programmers to quickly start using
1633 the SilcClientOperation functions in their application.
1634 Updated the lib/silcclient/README as well to tell about this
1635 nice file made available.
1637 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1639 * Call silc_server_remove_from_channels when removing client
1640 entry when NO_SUCH_CLIENT_ID was received. Affected file
1641 is silcd/command_reply.c.
1643 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * Added server & router operator statistics updating. Affected
1646 file silcd/packet_receive.c and silcd/command.c.
1648 * Fixed the SERVER_SIGNOFF notify handling on normal server
1649 not to save the history information for clients. Same was
1650 fixed earlier in remove_clients_by_server function, but not
1651 here. Affected file silcd/packet_receive.c.
1653 * Raised the default connection-retry count from 4 to 7 in
1654 server. Affected file silcd/server.h.
1656 * Cancel any possible reconnect timeouts when we start the
1657 key exchange. Affected file silcd/server.c.
1659 * Do not reconnect on connection failure when SCONNECT was
1660 given. Affected files silcd/server.[ch].
1662 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1666 * Fixed the NICK command to always give the unformatted
1667 nickname to the one giving the NICK command. If unformatted
1668 nickname is cached already it will be formatted and the
1669 local entry will always get the unformatted nickname.
1670 Affected file lib/silcclient/idlist.c.
1672 * Fixed some double frees from client library commands.
1673 Affected file is lib/silcclient/command.c.
1675 * Fixed CUMODE command in server to assure that no one can
1676 change founder's mode than the founder itself, there was a
1677 little bug. Affected file silcd/command.c.
1679 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1681 * Removed the SilcClientCommandDestructor from the client
1682 libary, it is not needed anymore. Affected files are
1683 lib/silcclient/silcapi.h, command[_reply].[ch],
1684 client_notify, idlist.c.
1686 * Fixed GETKEY command to first resolve client, and then
1687 resolve the server only if the client was not found, instead
1688 of resolving both at the same time. Affected file is
1689 lib/silcclient/command.c.
1691 * Added silc_client_start_key_exchange_cb and lookup the
1692 remote hostname and IP address before starting the key
1693 exchange with server. The affected file is
1694 lib/silcclient/client.c.
1696 * The server's public key is now saved using the IP address
1697 of the server and not the servername for the filename.
1698 The hostname public key filename is checked as an fall back
1699 method if the IP address based filename is not found.
1701 Fixed the GETKEY command to save the fetched server key
1702 in correct filename.
1704 Print the remote server's hostname now when new key is
1705 received during connection process. Affected file is
1706 irssi/src/silc/core/client_ops.c.
1708 * Return always our own public key to the client if it asks
1709 for it with GETKEY command. Affected file silcd/command.c.
1711 * Removed the use_auto_addr variable from default config
1712 file since it was in wrong section. Affected file is
1715 * Fixed TOPIC_CHANGE notification to not route it when it
1716 was sent using silc_server_send_notify_to_channel function.
1717 Affected file silcd/command.c.
1719 * Fixed silc_server_send_notify_kicked to send the kicker's
1720 Client ID also, it was missing. Affected files are
1721 silcd/command.c, silcd/packet_send.[ch].
1723 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1725 * Do not save client history information in SERVER_SIGNOFF.
1726 Fixes the bug in normal server that it does not detect
1727 the client becoming valid after the server becomes back
1728 online. Affected file silcd/server_util.c.
1730 * Added `sock_error' field into the SilcSocketConnection
1731 context. When error occurs during socket operation (read
1732 or write) the error is saved. Added also new function
1733 silc_socket_get_error to return human readable socket error
1734 message. Affected files are lib/silcutil/silcsockconn.[ch],
1735 lib/silcutil/unix/silcunixsockconn.c, and
1736 lib/silcutil/win32/silcwin32sockconn.c.
1738 * The server now prints the socket error message in the
1739 signoff for client. Affected file silcd/server.c.
1741 * Fixed the `created' channel information sending from router
1742 to server in JOIN command. Checks now whether the channel
1743 really was created or not and set it according that.
1745 Fixed the JOIN command to use the client entry's current
1746 ID during the joining procedure instead of the one it sent
1747 in the command (it is checked though), since it can change
1748 between the packet processing and command processing, and
1749 would just case unnecessary pain in the client end. Affected
1750 file silcd/command.c.
1752 * Fixed a channel key payload sending to use correct channel
1753 ID when the server was forced to change the channel's ID by
1754 router. Router sent the key payload with the old Channel ID.
1755 Affected file silcd/packet_receive.c.
1757 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Call silc_server_save_channel_key only if the key payload
1760 was provided in the JOIN command's command reply. Affected
1761 file silcd/command_reply.c.
1763 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1765 * Fixed silc_mp_sizeinbase to return the value correctly with
1766 MPI. Affected file lib/silcmath/mp_mpi.c.
1768 * Fixed the stop_server signal to correctly stop the scheduler
1769 and gracefully stop the server when SIGTERM or SIGINT signals
1770 are received. Affected file silcd/silcd.c.
1772 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1774 * Simple handling of TERM and HUP signals. Also added some log
1775 flushing call around. Affected file is
1778 * Fixed small bugs in silclog.c. Now buffering output will take
1779 effect after 10 seconds since startup: This will ensure that
1780 no important startup messages are lost. Also output redirection
1781 will preserve original format ([Date] [Type] message).
1782 Affected file is lib/silcutil/silclog.c.
1784 * Added two options to the config file, in the logging section:
1785 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1786 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1788 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1790 * Do not print the warning about log files not being initialized
1791 more than once to avoid excess logging. Affected file is
1792 lib/silcutil/silclog.c.
1794 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1795 the SIM copying in make install in Makefile.am.pre.
1797 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1799 * Rewritten silclog APIs. Globally interesting changes follows:
1800 silc_log_set_files() changed to silc_log_set_file().
1801 silc_log_set_callbacks() changed to silc_log_set_callback().
1802 ROBOdoc documented silclog header file.
1803 SilcLogCb now returns bool to wether inihibit the default
1804 handler or not (to keep the old behaviour return always TRUE).
1805 The new APIs should also fix the problem of the
1806 silcd_error.log file that was written in the current directory.
1809 Log files streams will remain opened after silc_log_set_file()
1810 call, means less CPU usage notably on high traffic servers.
1811 File streams are now full buffered, and flushed to the disk
1812 every 5 minutes, lesses HD activity and CPU usage.
1813 Messages can be redirected, allowing admins to configure
1814 one single logfile for all server messages.
1815 the silc_log_quick global variable to activate fast-logging.
1816 Affected files lib/silcutil/silclog.[ch]
1818 * Changed some code to conform new silclog APIs. Affected
1819 files are doc/example_silcd.conf.in, silcd/server.c
1820 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1823 * Fixed a memory leak that could occur in some situations.
1824 Affected file silcd/serverconfig.c.
1826 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1828 * Added the silc_client_del_client to remove the client from
1829 all channels as well. Affected file lib/silcclient/idlist.c.
1831 * Fixed the client library to correctly remove the client
1832 from all channels when the client entry is being destroyed.
1833 Affected file lib/silcclient/client_notify.c, command.c.
1835 * Added auto-nicking support to the client library. If the
1836 applicatio now sets client->nickname it will be sent to the
1837 server after connecting by the library. This way for example
1838 SILCNICK (or IRCNICK) environment variables will have effect
1839 and always change the nickname automatically to whatever
1840 it is wanted. Affected file lib/silcclient/client.[ch].
1842 * Renamed silc_server_command_bad_chars to the
1843 silc_server_name_bad_chars and moved it to the
1844 silcd/server_util.[ch]. Added also new function
1845 silc_server_name_modify_bad to return nickname that
1846 includes bad characters as new nickname without those
1847 bad characters. This check and modify is now used in
1848 silc_server_new_client when the username is initially set
1849 as nickname, so it must be checked to be valid nickname.
1850 Affected file silcd/packet_receive.c.
1852 * The nickname length is now taken from the packet for real
1853 and not trusted to strlen() since it clearly can return
1854 wrong length for nickname including bad characters. This
1855 also applies to channel names. Affected file silcd/command.c.
1857 * Removed the lib/silcsilm/modules directory. Modules are now
1858 compiled into the lib/silcsim. Fixed the copying of the
1859 modules to follow symbolic links in Makefile.am.pre.
1861 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1863 * Fixed silc_string_regexify list creation. Fixes bugs with
1864 BAN and INVITE commands in server. The affected file is
1865 lib/silcutil/unix/silcunixutil.c.
1867 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1869 * Removed the command destructor entirely from the server's
1870 command and command reply routines. It is not needed, and
1871 its usage was buggy and caused crashes. Affected files are
1872 silcd/command[_reply].[ch].
1874 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Cancel protocol and NULL sock->protocol if timeout
1877 occurred during protocol. Affected file silcd/server.c.
1879 * Cancel protocol timeouts always before calling the final
1880 callback, to assure that after final callback is called
1881 no other state will be called for the protocol anymore.
1882 Affected file silcd/protocol.c.
1884 * Print error log if incoming connection configuration could
1885 not be found. Affected file silcd/server.c.
1887 * Fixed JOIN command to correctly save the founder mode
1888 to the client on normal SILC server, when the channel
1889 was created by the router. Affected file silcd/command.c.
1891 * Fixed LIST command (hopefully) to send correct reply
1892 packets. Affected file silcd/command.c.
1894 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1896 * The silc_packet_receive_process now returns FALSE if the
1897 read data was invalid packet, and TRUE if it was ok.
1899 The server now checks that if unauthenticated connection
1900 sends data and its processing fails the server will close
1901 the connection since it could be a malicious flooder.
1903 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1905 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Make sure the warning about error opening a log file is
1908 printed only once and not everytime it fails (produces
1909 too much useless log). Affected file lib/silcutil/silclog.c.
1911 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1913 * Made the silc_server_daemonise() function more readable.
1914 Affected file silcd/server.c.
1916 * Pid file is now optional, the user may comment it out from
1917 the config file. Removed define SILC_SERVER_PID_FILE, we
1918 don't need a default any longer. Affected file
1919 configure.in.pre, lib/Makefile.am.pre.
1921 * Make some use of the pid file. The server now dies at startup
1922 if it detects a valid pid file on his path. The server would
1923 die anyway in this circumstance, because of the bind() failure.
1924 Affected file silcd/silcd.c.
1926 * No longer compiling lib/dotconf.
1928 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1930 * Fixed JOIN command parsing not to crash. Affected file
1931 lib/silcclient/command.c.
1933 * Fied the NICK_CHANGE notify to add the new client entry
1934 even it is resolved. This removes an <[unknown]> nick
1935 thingy bug in the client. Affected file is
1936 lib/silcclient/client_notify.c.
1938 * Do not try to allocate 0 bytes (efence does not like it)
1939 in lib/silccore/silccomand.c when encoding payload.
1941 * Do not take IRCNICK as nickname in Irssi SILC client since
1942 it is not possible to set nickname before hand connecting
1943 the server (TODO has an entry about adding auto-nicking
1946 * Changed the silc_server_command_pending to check whether
1947 there already exists an pending entry with the specified
1948 command, command identifier and pending callback. This is
1949 to fix IDENTIFY and WHOIS related crashes that may register
1950 multiple pending commands with same identifier. Affected
1951 file silcd/command.c.
1953 * Fixed the server to reconnect to the router even if it
1954 was already reconnecting and EOF was received. This to
1955 fix a possibility that the server wouldn't ever try to
1956 auto-reconnect to the router. Affected file silcd/server.c.
1958 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1960 * Fixed the server's password authentication to use the
1961 length of the locally saved password, and not the one
1962 sent in the packet. Affected file silcd/protocol.c.
1964 * Fixed same password authentication problem in the
1965 Authentication Payload handling routines in
1966 lib/silccore/silcauth.c.
1968 * Yet another password authentication problem fixed with
1969 channel password handling in silcd/command.c.
1971 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * If first character of string in silc_parse_userfqdn is '@'
1974 then do not parse it. Affected file is
1975 lib/silcutil/silcutil.c.
1977 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Fixed minor bug in IDENTIFY command reply sending, which
1980 caused various weird problems during JOIN when it was
1981 resolving names for users. Affected file silcd/command.c.
1983 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1985 * Fixed the IDENTIFY command reply sending to chech better valid
1986 clients. It was possible to send incomplete list of replies.
1987 Affected file silcd/command.c.
1989 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Added silc_client_command[s]_[un]register functions now to
1992 dynamically register the commands in client library. Removed
1993 the static table of commands. This allows the client library
1994 to call commands without causing the application to know about
1995 what commands library has called.
1997 Removed the INFO command reply kludge to detect when the command
1998 was called by library. Now library use its own command reply
1999 function for INFO command.
2001 Added function silc_client_command_call to call a command.
2002 Application can use it to call command, not access the structure
2005 Now all commands that are sent by the client library (not
2006 explicitly sent by application) use own command reply functions.
2008 Affected files around lib/silcclient/ and in
2009 irssi/src/silc/core/.
2011 * Fixed the WHOIS command reply sending to chech better valid
2012 clients. It was possible to send incomplete list of replies.
2014 Fixed the WHOIS and IDENTIFY to send the request to router
2015 if normal server did not do it and did not find any results.
2017 Affected file silcd/command.c.
2019 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2021 * Moved the internal data from SilcClient context into its
2022 own file, not accesible to application. Affected files
2023 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2024 and other files in client library.
2026 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2028 * Added doc/examples installation target in Makefile.am.pre.
2031 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2034 commands the found client entry will be removed from the
2035 cache, after notifying application about the error. Affected
2036 file lib/silcclient/command_reply.c.
2038 * Changed the /MSG to check for exact nickname user gave, and
2039 not let `nick' match `nick@host' if it is only one found. Now,
2040 user must type the exact nickname (like nick@host2) even if
2041 there are no more than one same nicks found. This is to avoid
2042 a possibility of sending nickname to wrong nickname since
2043 `nick' could match `nick@host'. Affected file is
2044 irssi/src/core/silc-servers.c.
2046 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2048 * Do not print "you are now server operator" or similar when
2049 giving /away command. Affected files are
2050 irssi/src/silc/core/client_ops.c, silc-servers.h.
2052 * Made the silc_server_command_pending_error_check to send
2053 the same command reply payload it received back to the
2054 original sender of the command. This way all arguments
2055 that was received by the server will be received by the
2056 client too. Affected file silcd/command.c.
2058 * Added the silc_idcache_add to return the created cache entry
2059 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2061 * Add global clients to expire if they are not on any channel.
2062 This is because normal server will never know if they signoff
2063 if they are not on any channel. The cache expiry will take
2064 case of these entries. This is done by normal servers only.
2065 The affected files are silcd/command_reply.c,
2066 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2068 * If server receives invalid ID notification for WHOIS or
2069 IDENTIFY and the ID exists in the lists, it is removed.
2070 Affected file silcd/command_reply.c.
2072 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2073 in client then client entry that it matches is searched and
2074 the nickname is printed on the screen for user. Affected
2075 file irssi/src/silc/core/client_ops.c.
2077 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Use cache entry expire time in the LIST command reply to
2080 purge old entries from the cache after the LIST command
2081 reply has been received. This way we don't have non-existent
2082 entries in the cache for too long. Affected file is
2083 silcd/command_reply.c.
2085 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * If we are normal server, and we've not resolved client info
2088 in WHOIS or IDENTIFY from router, and it is global client,
2089 we'll check whether it is on some channel. If it is not
2090 then we cannot be sure about its validity and will resolve it
2091 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2092 file silcd/command.c.
2094 * Search channel by name (if possible) rather than by ID
2095 in IDENTIFY command's command reply. Affected file is
2096 silcd/command_reply.c.
2098 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2101 Updated specs and implemented it. Affected file silcd/command.c,
2102 silcd/packet_send.c and silcd/packet_receive.c.
2104 * Implemented the <founder auth> payload handling in the JOIN
2105 command. If provided all conditions for channel joining
2106 except requirement to provide correct passphrase can be
2107 overrided by the channel founder. Updated the protocol specs.
2108 Affected file silcd/command.c.
2110 Added support for founder auth in JOIN command in client
2111 library. Fixed the parsing of the JOIN command now to support
2112 all options as they should be. The affected file is
2113 lib/silcclient/command.c.
2115 * Optimized the WHOIS and IDENTIFY commands to send the request
2116 to router only if it includes nicknames or other names. If
2117 they include only IDs then check the local cache first before
2118 routing. Affected file is silcd/command.c.
2120 * Added channels topic announcements. Affected file is
2121 silcd/packet_receive.c and silcd/server.c.
2123 * Fixed the silc_server_send_notify_topic_set to really destine
2124 the packet to channel. Affected file silcd/packet_send.c.
2126 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2127 library. Affected file lib/silcclient/client_notify.c.
2129 * Added UMODE announcements. Affected file silcd/server.c.
2131 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Memory leak fixes in:

2140 lib/silccore/silccommand.c
2141 lib/silccore/silcidcache.c
2146 * ROBOdoc documented the lib/silcske/groups.h file and a
2147 bit changed the interface for better.
2149 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2151 * Update the client entry context in the ID cache after
2152 nick change. Affected file lib/silcclient/command.c.
2153 Fixes the CUMODE command when regaining founder privileges,
2154 and a little WHOIS problem.
2156 * Fixed silc_net_gethostbyname to correctly call the
2157 inet_ntop. Affected file lib/silcutil/silcnet.c.
2159 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2161 * Added IPv6 support checking to the configure.in.pre, added
2162 also --enable-ipv6 option to override the check. Affected
2163 file configure.in.pre.
2165 * The silc_thread_create now calls the start function
2166 directly if threads support is not compiled in. Removes
2167 ugly #ifdef's from generic code. Affected files are
2168 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2170 * Added silc_net_gethostby[name/addr]_async to asynchronously
2171 resolve. Affected files are lib/silcutil/silcnet.[ch].
2173 * Added support for rendering IPv6 based server, client and
2174 channel IDs. Affected file lib/silcutil/silcutil.c.
2176 * Added support for creating IPv6 based server IDs. Affected
2177 file is silcd/serverid.c.
2179 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2181 * Added silc_net_gethostby[addr/name] into the
2182 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2183 routines. Added silc_net_is_ip[4/6]. Affected file is
2184 lib/silcutil/unix/silcunixnet.c. All routines that take
2185 address as argument now supports both IPv4 and IPv6 addresses.
2187 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2189 * Fixed LIST command reply sending in server. Affected file
2192 * Server now sends the kicker's client ID in the KICK notify
2193 to the kicked client. Affected file silcd/command.c.
2195 * The client library now parses the kickers client ID and
2196 UI displays it. Affected files lib/silcclient/client_notify.c
2197 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2199 * Made all payload parsing function prototypes consistent.
2200 They all take now const unsigned char * and uint32 pair as
2201 the payload data instead of SilcBuffer. Changes all around
2202 the source tree. Other unsigned char* -> const unsigned char*
2203 changes around the tree as well.
2205 * Optimized SFTP client and server packet sending not to
2206 allocate new buffer for each packet but to recycle the
2207 first allocated buffer. Affected files are
2208 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2210 * Optimized the SFTP client to use SilcList instead of
2211 SilcDList for requests, because it is faster. Affected file
2212 is lib/silcsftp/sftp_client.c.
2214 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2215 into lib/silccore/silcid.[ch].
2217 Renamed silcpayload.[ch] into silcargument.[ch].
2219 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * If client entry is deleted with active key agreement
2222 session, abort the session.
2224 The silc_client_abort_key_agreement now calls the completion
2225 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2227 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2230 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2232 * Don't use __restrict in older GCC's. Affected file is
2233 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2235 * silc_net_localhost now attempts to reverse lookup the
2236 IP/hostname. Affected file lib/silcutil/silcnet.c.
2238 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2239 command. It can be used to gain founder privileges at
2240 the same time when joining the channel.
2242 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2243 kicker's client ID as well. Updated protocol specs.
2245 Defined that the server must send SILC_COMMAND_IDENTIFY
2246 command reply with error status to client who sent
2247 private message with invalid client ID.
2249 Updated the protocol specification.
2251 * Added silc_server_send_command_reply to send any
2252 command reply. Affected file silcd/packet_send.[ch].
2254 * Added silc_id_payload_encode_data to encode ID payload
2255 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2257 * The server now send IDENTIFY command reply with error
2258 status if client ID in private message is invalid. Affected
2259 file silcd/packet_receive.c.
2261 * Save the server key file with server's IP address in
2262 the filename instead of hostname. The affected file is
2263 irssi/src/silc/core/client_ops.c.
2265 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2267 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2270 * Added libtool support for compiling shared objects in
2271 lib/silcsim. Affected file configure.in.pre and
2272 lib/silcsim/Makefile.am. Original patch by cras.
2274 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Pid file configuration, and server's config file fixes
2277 patch by toma. Updated CREDITS file.
2279 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Fixed silc_client_channel_message to not try to decrypt
2282 the message twice if it resolved the destination client
2283 information. This could cause of dropping one channel
2284 message. Affected file lib/silcclient/client_channel.c.
2286 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2288 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2289 lib/silcclient/client.c. This function is used when the SILC
2290 Client is run under some other scheduler, or event loop or
2291 main loop. On GUI applications, for example this may be
2292 desired to used to run the client under the GUI application's
2293 main loop. Typically the GUI application would register an
2294 idle task that calls this function multiple times in a second
2295 to quickly process the SILC specific data.
2297 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2299 * Fixed silc_server_drop() for dropping the supplementary
2300 groups as well, this could cause a security hole on some
2303 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2308 * Write PID file after dropping privileges. Added -F option
2309 to run server on foreground. A patch by debolaz.
2310 Affected files silcd/server.c, silcd/silcd.c.
2312 * Fixed MOTD to return the MOTD file server name. Affected
2313 file silcd/command.c.
2315 * Added INFO command reply handling to the Irssi SILC Client.
2316 Affected file irssi/src/silc/core/client_ops.c.
2318 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Fixed the silc_idcache_list_* routines to really support
2321 the dynamic list. Fixes a crash. Affected file is
2322 lib/silccore/silcidcache.c.
2324 * Fixed the LIST command reply to really call LIST command's
2325 pending callbacks. Affected file silcd/command_reply.c.
2327 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2329 * Update conn->local_entry->nickname after giving NICK
2330 command. Affected file lib/silcclient/command.c.
2332 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2334 * Added the [pid] option to the silcd configuration file
2336 Affected files: serverconfig.[ch] and silcd.c
2338 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2340 * Save fingerprint in WHOIS command reply in server.
2341 Affected file silcd/command_reply.c.
2343 * Fixed NICK commands pending callback registration.
2344 Affected file lib/silcclient/command.c.
2346 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2348 * Use ++server->cmd_ident when sending commands in server,
2349 instead of random number. Affected file silcd/command.c.
2351 * Fixed GETKEY command reply to call actually GETKEY pending
2352 command callbacks. Affected file silcd/command_reply.c.
2354 * A bit stricter check for nicknames. Check for same nickname
2355 in NICK command also. Affected file silcd/command.c.
2357 * Do not call INFO command everytime client ID changes, only
2358 during first connecting. Affected file lib/silcclient/client.c.
2360 * Set the new nickname only after successful command reply for
2361 NICK command is returned by server. Affected file
2362 lib/silcclient/command.c.
2364 * Remove nicknames from nicklist during server_signoff notify.
2365 Should fix /NAMES bit more. The affected file is
2366 irssi/src/silc/core/silc-channels.c.
2368 * Added `fingerprint' field to the SilcIDListData in the
2369 silcd/idlist.h to hold the fingerprint of the client's
2372 Send the fingerprint of the client's public key in WHOIS
2375 Affected files silcd/command.c, and silcd/idlist.[ch].
2377 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2378 create fingerprint from given data.
2380 * Show the fingerprint of the client's public key in WHOIS.
2381 Affected files irssi/src/module-formats.[ch] and
2382 irssi/src/silc/core/client_ops.c.
2384 * Format the multiple same nicknames also during JOIN and
2385 NICK_CHANGE notifys. Affected file is
2386 lib/silcclient/client_notify.c.
2388 * Do not print error on screen for invalid private message
2389 payload since it can come if someone is sending private
2390 messages with wrong key. Affected file
2391 lib/silccore/silcprivate.c.
2393 * Fixed multiple concurrent /PING crash. Affected file
2394 lib/silcclient/command.c.
2396 * Changed the wrong ID encoding. All IP addresses must be
2397 in MSB first order in encoded format. They were encoded
2398 wrong and was in LSB format. Affected files are
2399 silcd/serverid.c, lib/silcutil/silcutil.c.
2401 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2403 * Call the `connect' client operation through the scheduler
2404 in case of error. Affected file lib/silcclient/client.c.
2406 * Call the `failure' client operation even if the error
2407 occurred locally during a protocol. Affected file is
2408 lib/silcclient/protocol.c.
2410 * Added support of sending LIST command to router from normal
2411 server. This way normal server can get list of all channels
2412 in the network too. Fixed the channel list sending in the
2413 server too. Affected files are silcd/command.c, and
2414 silcd/command_reply.[ch].
2416 * Added silc_server_update_channels_by_server and
2417 silc_server_remove_channels_by_server. They are used during
2418 disconnection of primary router and in backup router protocol.
2419 Affected file silcd/server_util.[ch], silcd/server.c and
2420 silcd/server_backup.c.
2422 * Fixed channel adding to global list in IDENTIFY command
2423 reply in server. Affected file silcd/command_reply.c.
2425 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * If the incoming packet type is REKEY or REKEY_DONE process
2428 that packet always synchronously. Fixes yet another MAC
2429 failed error on slow (dialup) connections. Affected file
2430 lib/silcclient/client.c and silcd/server.c.
2432 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Call check_version SKE callback for initiator too. Affected
2435 file lib/silcske/silcske.c.
2437 * Implemented fix for security hole found in the SKE that was
2438 fixed in the specification few days back; the initiator's
2439 public key is now added to the HASH value computation.
2440 Added backwards support for the old way of doing it too, for
2441 old clients and old servers. Affected file is
2442 lib/silcske/silcske.c.
2444 * Enabled mutual authentication by default in SKE. If initiator
2445 is not providing mutual authentication the responder will
2446 force it. This will provide the proof of posession of the
2447 private key for responder. The affected files are
2448 lib/silcclient/protocol.c and silcd/protocol.c.
2450 * Do not cache anymore the server's public key during SKE.
2451 We do mutual authentication so the proof of posession of
2452 private key is done, and if the server is authenticated in
2453 conn auth protocol with public key we must have the public
2454 key already. Affected file silcd/protocol.c.
2456 * Added new global debug variable: silc_debug_hexdump. If
2457 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2458 file lib/silcutil/silclog.[ch].
2460 * Fixed compilation warning due to char * -> const char *.
2461 Affected files lib/silcutil/silcnet.h, and
2462 lib/silccore/silcauth.[ch].
2464 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Fixed CMODE command when new channel key was created. If
2467 the creation failed the old key was removed. Next time giving
2468 same command would crash the server since the old key was
2469 freed already. Affected file silcd/command.c.
2471 * Fixed the silc_server_announce_get_channels to not crash
2472 on reconnect. Affected file silcd/server.c.
2474 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Added silc_log_set_debug_string function to set a regex
2477 string to match for debug output. Only the function names,
2478 or filenames matching the given debug string is actually
2479 printed. This way it is possible to filter out those debug
2480 strings that user is not interested in.
2482 Fixed a bug in silc_string_regexify.
2484 Affected files lib/silcutil/silclog.[ch], and
2485 lib/silcutil/unix/silcunixutil.c.
2487 * Changed the -d options in both server and Irssi SILC client
2488 to take the debug string as argument. Affected files
2489 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2491 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Added silc_hash_babbleprint to create a Bubble Babble
2494 Encoded fingerprint. The encoding is developed by Antti
2495 Huima (draft-huima-babble-01.txt), and it creates human
2496 readable strings out of binary data. Affected file
2497 lib/silccrypt/silchash.[ch].
2499 * Print the babble print now in addition of fingerprint as well
2500 in Irssi SILC client. Affected files are
2501 irssi/src/fe-common/silc/module-formats.[ch],
2502 irssi/src/fe-common/silc/core/client_ops.c.
2504 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Fixed a security problem found in SKE. The initiator's
2507 public key too is now added to the HASH hash value creation
2508 which is signed by the responder to create the SIGN value.
2509 This will prevent anyone in the middle to lie to the responder
2510 about the initiator's public key. If this is done now, the
2511 man in the middle will get caught. Updated the protocol
2514 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Better installation directory handling. Configure module
2517 paths and other paths automatically to example_silc* files
2518 in doc/. A patch by toma.
2520 * Fixed compiler warning from MPI library, and from SILC RNG.
2523 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2524 It can be configured with ./configure. A patch by toma.
2526 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2528 * Find correct make to use in prepare-clean. A patch by
2529 toma. Affected file prepare-clean.
2531 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2533 * Added irssi variables use_auto_addr, auto_bind_ip,
2534 auto_bind_port and auto_public_ip.
2536 * Changed the interface for silc_client_send_key_agreement
2537 in lib/silcclient/silcapi.h
2541 irssi/src/silc/core/silc-core.c
2543 lib/silcclient/silcapi.h
2544 irssi/src/silc/core/silc-channels.c
2545 lib/silcclient/client_keyagr.c
2548 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Added silc_pkcs_public_key_compare to compare two
2551 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2553 * Check that the client who set the founder mode on the
2554 channel is the same client that is giving the founder
2555 mode to itself. It is done by comparing the saved public
2556 key (it is saved even in the authentication is passphrase).
2557 Affected file silcd/command.c.
2559 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2561 * Do not process packet for disconnected socket connection.
2562 Affected file lib/silccore/silcpacket.c.
2564 * Process the DISCONNECT packet through scheduler in the
2565 client library. Affected file lib/silcclient/client.c.
2567 * Fixed the silc_client_packet_parse to not to increase
2568 the packet sequence number if the conn->sock and the
2569 current socket connection is not same. This can happen
2570 for example during key agreement when the conn includes
2571 multiple socket connections (listeners). Affected file
2572 lib/silcclient/client.c.
2574 * The sender of the file transfer request now provides also
2575 the pointer (listener) for the key exchange protocol. If
2576 the listener cannot be created then it sends empty key
2577 agreement and lets the receiver provide the listener.
2579 Added `local_ip' and `local_port' arguments to the
2580 silc_client_file_send. If they are provided they are used,
2581 if not then it will attempt to find local IP address, if
2582 not found or bind fails then the remote client will provide
2585 Affected files are lib/silcclient/client_ftp.c and
2586 lib/silcclient/silcapi.h.
2588 * Extended the FILE SEND command to support defining the
2589 local IP and port for key exchange listener. They are
2590 optional. Affected file irssi/src/silc/core/silc-servers.c.
2592 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2594 * Defined to WHOIS command reply the sending of fingerprint
2595 of the client's public key (if the proof of posession of the
2596 corresponding private key is verified by the server).
2597 Updated to the protocol specification.
2599 * Added support of receiving the client's public key's
2600 fingerprint in command reply in client library. Affected
2601 file is lib/silcclient/command_reply.c, and
2602 lib/silcclient/idlist.[ch].
2604 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Do not send over 128 chars long nickname to the server
2607 in NICK command. Affected file lib/silcclient/command.c.
2609 * Do not send over 256 chars long channel names to the server
2610 in JOIN command. Affected file lib/silcclient/command.c.
2612 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Assure that silc_server_close_connection cannot be called
2615 twice for same socket context. Affected file is

2657 client library. Affected file lib/silcclient/client_prvmsg.c.
2659 * Do not actually remove the client directly from ID cache
2660 during SERVER_SIGNOFF, but invalidate it. This way we
2661 preserve the WHOWAS info for the client. Affected file
2662 silcd/server_util.c.
2664 * Fixed SERVER_SIGNOFF notify handling in the server. The
2665 server is now able to process incoming SERVER_SIGNOFF notify
2666 for a server that it doesn't even know about. It will remove
2667 the clients provided in the notify. Affected file
2668 silcd/packet_receive.c.
2670 * Check for partial packet in data queue after every packet that
2671 was found from the queue. Return and wait for more data if
2672 there is partial data in queue. Affected file is
2673 lib/silccore/silcpacket.c.
2675 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2690 irssi/src/fe-common/silc/module-formats.[ch].
2692 * Wrote a help file for FILE command.
2694 * Added silc_rng_global_get_byte_fast to get not-so-secure
2695 random data as fast as possible. Random data is read from
2696 /dev/urandom if available and from the SILC RNG if not
2697 available. It is used in padding generation. Affected file
2698 lib/silccrypt/silcrng.[ch].
2700 * All packets in client library are now processed synchronously.
2701 Optimized packet processing a lot. Affected file
2702 lib/silcclient/client.c.
2704 * All server connection packets are processing synchronously
2705 now in server, to optimize packet processing. Affected file
2708 * Include files are installed now only in Toolkit distribution
2709 if make install is given. Affected files: all Makefile.am's.
2711 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Assure that silc_client_notify_by_server_resolve does not
2714 resolve the client information multiple times. If it cannot
2715 be found by the first it cannot be found at all. Affected
2716 file lib/silcclient/client_notify.c.
2718 * Fixed WHOWAS command reply calling. Affected file
2719 lib/silcclient/command_reply.c.
2721 * Removed all references to silc_idlist_get_client from the
2722 Irssi SILC client since that call is internal call used by
2723 the library. The Irssi SILC client will use now client
2724 retrieval functions found in silcapi.h.
2726 * Fixed a bug in resolving nickname info before sending
2727 private message. It used freed memory. Affected file
2728 irssi/src/silc/core/silc-servers.c.
2730 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * Assure my_channels statistics cannot go negative in server.
2733 Affected files silcd/server.c, silcd/server_util.c.
2735 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2749 * Added silc_net_localip to return local host's IP address.
2750 Affected file lib/silcutil/silcnet.[ch].
2752 * If key exchange or rekey protocol is active for a connection
2753 parse all packets syncronously since there might be packets
2754 in packet queue that we are not able to process without first
2755 processing packets before them. Affected file silcd/server,
2756 lib/silcclient/client.c.
2758 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2759 whether library should continue processing the packet.
2760 Affected file lib/silccore/silcpacket.h.

2806 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2807 is incomplete and is being resolved, it won't be resolved
2810 Make sure also that USERS command reply does not resolve
2811 twice information. Affected file is
2812 lib/silcclient/command_reply.c.
2814 Make sure that silc_client_get_clients_by_list does not
2815 resolve twice same information.
2817 * Check for valid client->id in the silc_server_free_client_data.
2818 Affected file silcd/server.c.
2820 * Fixed /GETKEY nick@server not to crash if the server entry
2821 is not found. Affected file lib/silcclient/command.c.
2823 * Fixed the silc_server_check_cmode_rights to check the
2824 requested modes correctly. Affected file silcd/command.c.

2829 Affected file silcd/command.c.
2831 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2833 * Call the silc_server_udpate_servers_by_server in the
2834 primary router that comes back online in the backup resuming
2835 protocol. Otherwise it routes packets wrong. Affected file
2836 silcd/server_util.[ch], silcd/server_backup.c.
2838 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2840 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2841 lib/silcutil/silcbuffmt.[ch].
2843 * Redefined the SILC packet header to include the padding
2844 length. Affected file lib/silccore/silcpacket.[ch].
2846 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2847 length for maximum padding up to 128 bytes). Affected
2848 file lib/silccore/silcpacket.h.
2850 * Removed all backwards support for old 0.5.x MAC thingies.
2851 The SILC packet header change makes it impossible to be
2852 backwards compatible.
2854 * Send the ENDING packet with timeout in the backup resuming
2855 protocol. This is to assure that all routers has connected
2856 to the primary router. Affected file silcd/server_backup.c.
2858 * Changed the RNG to take the first IV from random data. It
2859 used to take it from zero actually. Changed the RNG also
2860 to use /dev/urandom during session. /dev/random is used
2861 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2863 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Changed the SILC packet header to have the first two bytes
2866 (the packet length) encrypted. Affected files aroung the
2867 code tree, lib/silccore/silcpacket.[ch]. Removed the
2868 SilcPacketCheckDecrypt callback. It is not needed anymore
2869 since the silc_packet_receive_process will determine now
2870 whether the packet is normal or special.
2872 * Implemented the unidirectional MAC keys. Affected files
2873 lib/silcske/silcske.c, silcd/protocol.c and
2874 lib/silcclient/protocol.c.
2876 * Implemented the packet sequence number to the MAC computation.
2877 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2878 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2879 lib/silcclient/protocol.c.
2881 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Allow backup router to announce servers. All servers
2884 announced by backup router are added to the global list
2885 automatically. Update hte server's socket to our primary
2886 router also when backup router announces a server.
2887 Affected file silcd/packet_receive.c.
2889 * Do not update the client->router in the function
2890 silc_server_udpate_clients_by_server if the client is on
2891 global list. We might fail to find any specific server
2892 for locally connected clients and local cell clients. They
2893 should still use the `from' and not `to' as client->router.
2894 This fixes backup router resuming protocol. Affected file
2895 silcd/server_util.c.
2897 * Decrease channel statistics count only if the channel
2898 deletion worked. Affected files are silcd/server.c and
2899 silcd/server_util.c.
2901 * Added silc_server_update_servers_by_server to update origin
2902 of all server entries. Used during backup router protocol.
2903 Affected files silcd/server_util.[ch], silcd/server.c. and
2904 silcd/backup_router.c.
2906 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2907 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2908 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2909 lib/silccrypt/silchmac.c.
2911 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Assure that router cannot reroute the same channel message
2914 to the sender. Affected file silcd/packet_receive.c.
2916 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Made better checks that the channel message is not sent
2919 to the router it came from. Affected file is
2920 silcd/packet_send.c. Fixed memory leak too.
2922 * Announce informations for incoming router connection, but
2923 only after checking if it is replaced by backup router.
2924 Affected file silcd/packet_receive.c.
2926 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Fixed the backup resuming protocol to work in multiple
2929 router environment. Affected file silcd/server_backup.c.
2931 * Route packet only to one router in the function
2932 silc_server_packet_send_to_channel. Affected file is
2933 silcd/packet_send.c.
2935 * Fixed silc_server_send_notify_dest to set the broadcast
2936 flag. Fixed the silc_server_send_notify_topic to actually
2937 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2938 Affected file silcd/packet_send.c.
2940 * Changed the SFTP Filesystem interface. Changed the
2941 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2942 the filesystem operation function. The SilcSFTPFilesystem
2943 is now a context that is allocated by all filesystem allocation
2944 functions and it already includes the operations structure
2945 and filesystem specific context. It is given as argument
2946 now to the silc_sftp_server_start. This made the interface
2947 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2948 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2950 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * Changed the backup router adding and getting interfaces
2953 in the server. The router that will be replaced by the
2954 specified backup router is now sent as argument. Affected
2955 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2958 * Added silc_net_addr2bin_ne to return the binary form of
2959 the IP address in network byte order. Affected files
2960 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2962 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Check for existing server ID in silc_server_new_server
2965 and in silc_server_connect_to_router_final and remove the
2966 old entry if it exists. Affected file silcd/packet_receive.c,
2969 * Send the channel message always to only one router, either
2970 in upstream or downstream. Affected file is
2971 silcd/packet_send.c.
2973 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Wrote the definition of the backup resuming protocol to the
2976 protocol specification.
2978 * Removed one redundant channel key generation from normal
2979 server during joining procedure. Removed one redundant
2980 channel key sending from server to router during joining
2981 procedure. Affected file silcd/command.c.
2983 * Made minor bugfixes to the backup router resuming protocol.
2984 Affected file silcd/server_backup.c, server.c.
2986 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Added --disable-asm configuration option. Affected files
2989 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2992 * Implemented the backup resuming protocol that is used to
2993 resume the primary router position in the cell after the
2994 primary router comes back online. Affected files
2995 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2996 and silcd/server_util.[ch].
2998 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Sleep two (2) seconds after sending QUIT command to server.
3001 Affected file lib/silcclient/command.c.
3003 * Assure that if outgoing data buffer is pending do not force
3004 send any data. Affected file silcd/packet_send.c.
3006 * Assure that if outgoing data buffer is pending do not force
3007 send any data. Affected file lib/silcclient/client.c.
3009 * Implemented the backup router support when the primary router
3010 goes down. The servers and routers can now use the backup
3011 router as new primary router without loosing connectivity.
3013 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3016 in the server to indicate disabled entry. All data read
3017 from the connection will be ignored and no data is sent
3018 for entry that is disabled. Affected files are
3019 silcd/idlist.h, silcd/server.c.
3021 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Created SFTP client and server test programs in the
3024 lib/silcsftp/tests directory.
3026 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Implemented memory filesystem (virtual filesystem) for
3029 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3032 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * Implemented the SFTP (SSH File Transfer Protocol) to the
3035 lib/silcsftp. It includes SFTP client and SFTP server
3038 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Moved lib/silccore/silcprotocol.[ch] to the
3041 lib/silcutil library.
3043 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3044 take variable argument list pointer as argument. Affected
3045 file lib/silcutil/silcbuffmt.[ch].
3047 * Added silc_buffer_set function that is used to set data
3048 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3049 Affected file lib/silcutil/silcbuffer.h.
3051 * Changed various routines in the core library to use the new
3052 silc_buffer_set instead of allocating new buffer only for
3055 * Added 64-bit value formatting and unformatting support to the
3056 silc_buffer_[un]format routines. Affected file is
3057 lib/silcutil/silcbuffmt.[ch].
3059 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3060 to includes/bitmove.h.
3062 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3064 * Fixed channel user mode saving in client library. Affected
3065 file lib/silcclient/command[_reply].c.
3067 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Defined the file transfer to the SILC Protocol. Added
3070 new packet type SILC_PACKET_FTP and defined File Transfer
3071 Payload. The mandatory file transfer protocol is SFTP
3072 (SSH File Transfer Protocol). Affected file in addition
3073 of the internet draft is lib/silccore/silcpacket.h.
3075 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3076 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3077 is used as part of backup router protocol when the primary
3078 router of the cell is back online and wishes to resume
3079 the position as primary router.
3081 * Redefined the MAC generation keys in the protocol. The
3082 same key is not used anymore in both direction. Both
3083 direction will now use different keys for sending and
3084 receiving. This fixes a potential security flaw. This
3085 change causes incompatibilities in the protocol.
3087 * Redefined also the MAC computation from the packet.
3088 An packet sequence number is now added to the MAC
3089 computation. This prevents possible replay attacks against
3090 the protocol. This change too causes incompatibilities
3093 Added `sequence' field to the SilcPacketContext to hold
3094 the current sequence number for the packet.
3096 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Added `created' field to the SilcIDListData in the file
3099 silcd/idlist.h to indicate the time when the entry was
3102 * Added `created' field to the SilcChannelEntry too. Affected
3103 file silcd/idlist.h.
3105 * Added `creation_time' aguments to all the announcement functions
3106 in the server. If it is provided then only the entries that
3107 was created after the provided time frame are actually
3108 announced. Affected file silcd/server.[ch].
3110 * The protocol says that the Channel ID's IP address must be
3111 based on the router's IP address. Added check for this in
3112 the silc_server_new_channel when processing incoming New Channel
3113 Payload. Affected file silcd/packet_receive.c.
3115 * Print out the correct version with --version in SILC client.
3116 Affected file irssi/src/silc/core/silc-core.c.
3118 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Fixed WHOWAS command to check for completnes of the client
3121 entry always, not just when the command is coming from client.
3122 Affected file silcd/command.c.
3124 * Added new function silc_server_packet_queue_purge to purge the
3125 outgoing data queue to the network. After the function returns
3126 it is guaranteed that the outgoing packet queue is empty.
3127 Affected file silcd/packet_send.[ch].
3129 * Purge the outgoing packet queue in the rekey protocol's final
3130 callback to assure that all rekey packets go to the network
3131 before quitting the protocol. Affected file silcd/server.c.
3133 * Added silc_client_packet_queue_parse as similar function as
3134 in server to the client library. The affected file is
3135 lib/silcclient/client.c.
3137 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Splitted silcd/server.c and created silcd/server_util.[ch]
3140 for utility functions.
3142 * Added new socket flag SILC_SF_DISABLED to indicate that the
3143 connection is open but nothing can be sent to or received from
3144 the connection. Affected file lib/silcutil/silsockconn.[ch].
3145 The checking for disabled socket is checked in the low level
3146 silc_socket_write and silc_socket_read functions.
3148 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Allow only nicknames and channel names that fits into the
3151 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3153 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3155 * When processing JOIN command reply in server check that if
3156 the channel exists in our global list we'll move it the local
3157 list. Affected file silcd/command_reply.c.
3159 * Fixed the check whether client is joined on the channel already
3160 in JOIN command. Affected file lib/silcclient/command.c.
3162 * Fixed the JOIN command reply to check whether the channel
3163 already exists. Affected file lib/silcclient/command_reply.c.
3165 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Added silc_ske_status_string to map the SKE error numbers
3168 to readable strings. The affected files are
3169 lib/silcske/silcske[_status].[ch].
3171 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Do not show the private channels on the WHOIS channel list
3174 as it is not allowed by the protocol. The affected file is
3177 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Assure that the packet length digged from the actual packet
3180 is something sensible in the silc_packet_decrypt_rest_special
3181 in lib/silccrypt/silcpacket.c.
3183 * Free and NULL the allocated pointer in silc_hmac_alloc if
3184 the HMAC allocation fails. The affected file is
3185 lib/silccrypt/silchmac.c.
3187 * Print the selected security properties to the log files in
3188 the server. Affected file silcd/protocol.c.
3190 * Add SKE's reference counter even if calling the completion
3191 callback manually. Otherwise it goes negative, although it
3192 does not cause any problems. The affected file is
3193 lib/silcske/silcske.c.
3195 * Remove the client entry with short timeout after giving the
3196 KILL command. Affected file lib/silcclient/command.c.
3198 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3199 case all found clients are already disconnected (WHOWAS would
3200 found them) in the server. Affected file silcd/command.c.
3202 * Update the last_receive (time of last data received) to be
3203 updated only when received private or channel message so that
3204 the idle time showed in WHOIS makes more sense.
3206 * Added boolean field `valid' in to the SilcClientEntry in the
3207 client library to indicate whether the entry is valid or not.
3208 This fixes the nickname change bug on channel when changing
3209 the nickname to be same than the old (like nick to Nick) the
3210 nickname formatter doesn't set the new nick anymore to Nick@host.
3211 Affected file lib/silcclient/idlist.[ch].
3213 * Now actually fixed the nickname changing on disconnection.
3214 Added new function silc_change_nick to the Irssi SILC Client.
3215 Affected file irssi/src/silc/core/client_ops.c,
3216 irssi/src/silc/core/silc-nicklist.[ch].
3218 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Check that the public key exists in the GETKEY command before
3221 trying to encode it. Affected file silcd/command.c.
3223 * Print some notifications on received public keys with GETKEY
3224 command in the Irssi SILC Client. Affected files are
3225 irssi/src/fe-common/silc/module-formats.[ch],
3226 irssi/src/silc/core/client_ops.c.
3228 * Use IDENTIFY command to resolve the server information in the
3229 GETKEY command instead of INFO command. Affected file
3230 lib/silcclient/command.c.
3232 * All command reply functions in the client library now calls
3233 the pending command reply callbacks even if an error has
3234 occurred. The server has done this a long time and now it was
3235 time to move the client library to this as well. Now all
3236 errors can be delivered back to the pending command reply
3237 callbacks if necessary. Affected files are
3238 lib/silcclient/command[_reply].[ch].
3240 * Change the nickname on disconnection back to the username
3241 because in reconnect the server will enforce it to it anyway.
3242 Affected file irssi/src/silc/core/silc-servers.c.
3244 * Fixed a config file parsing bug in the Irssi SILC client.
3245 Affected file irssi/src/silc/core/clientconfig.c.
3247 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * When printing the channel mode on JOIN, verify that the
3250 channel key and channel's HMAC are valid. Affected file
3251 irssi/src/silc/core/client_ops.c.
3253 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3256 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3257 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3259 * Removed channel key rekey task deleting from the function
3260 silc_server_save_channel_key. Affected file silcd/server.c.
3261 Added explicit timeout task context instead that is used to
3262 delete the task if we are registering a new task before the
3263 new task has elapsed.
3265 * When channel key rekey occurs the client library now saves
3266 the old channel key for a short period of time (10 seconds) and
3267 is able to use it in case some is still sending channel
3268 messages encrypted with the old key after the rekey. Affected
3269 file lib/silcclient/[idlist.h|client_channel.c].
3271 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Added check to the silc_server_new_id_real to not accept
3274 new ID if it is the sender's own ID. Affected file is
3275 silcd/packet_receive.c.
3277 * Assure that we do not announce ourself or the one we've
3278 sending our announcements when we're router and are announcing
3279 servers to our primary router. Affected file silcd/server.c.
3281 * Fixed silc_server_command_identify_check_client to assemble
3282 correct WHOIS packet. It send corrupted WHOIS packet and
3283 caused problem with router to router connections. Affected
3284 file silcd/command.c.
3286 Fixed also silc_server_command_whois_check the same way
3287 as for the IDENTIFY command.
3289 * Added new SilcIDListStatus to the server in the SilcIDListData
3290 structure. The status now includes the current status of
3291 the entry (like registered, resolved etc.). Affected file
3292 silcd/idlist.[ch]. Defined a bunch of different status types
3293 as well. This replaced the old boolean registered field as well.
3295 Added resolve_cmd_ident field to the SilcClientEntry structure
3296 too so that if the entry is for example being resolved so
3297 another command may attach to the same pending command reply
3298 without requiring to resolve the same entry again. This concept
3299 should optimize the WHOIS and the IDENTIFY resolving under
3300 heavy load by taking away unnecessary resolving for entries
3301 that are being resolved already.
3303 Added support for adding multiple pending commands for one
3304 command idenfier. Affected file silcd/command[_reply].[ch].
3306 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3307 before deleting the data. Otherwise the hash table will have
3308 freed data in comparison functions. Affected file is
3309 silcd/command_reply.c.
3311 * Fixed silc_idlist_replace_client_id to add the new entry to
3312 the cache with NULL nickname. Otherwise there will be invalid
3313 memory as the nickname after the nickname is freed. Affected
3314 file silcd/packet_receive.c.
3316 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3317 saved into wrong slots because the previous number of entries
3318 was not taken into account. Affected file silcd/idlist.c.
3319 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3321 * If we are router and we receive JOIN notify to a channel that
3322 does not have any users then notified client is marked as the
3323 channel founder, as it is it. The affected file is
3324 silcd/packet_receive.c
3326 * Added to the extended hash table API's table_del_*ext functions
3327 the destructor as argument too, so that the caller can decide
3328 which destructor to use or whether to use destructor at all.
3329 Affected file lib/silcutil/silchashtable.[ch].
3331 * Fixed ID Cache purging. It actually deleted the entries from
3332 the hash table after the data was freed. The hash table ended
3333 up comparing freed memory. The affected file is
3334 lib/silccore/silcidcache.c.
3336 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Fixed Irssi SILC client's KILL command's HELP syntax.
3340 * The USERS command now resolves the detailed user information
3341 if the userinfo field is missing. Affected file is
3342 lib/silcclient/command_reply.c.
3344 * Do not print error in silc_file_read if the read file does
3345 not exist. Just silently return NULL. Affected file is
3346 lib/silcutil/silcutil.c.
3348 * Fixed the silc_log_output to not wine about NULL filename
3349 and to not create some bogus " " filename. Affected file is
3350 lib/silcutil/silclog.c.
3352 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Fixed various printing bugs on the user interface in the
3355 Irssi SILC Client. Minor changes that were forgotten from
3358 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Fixed the configure.in.pre and the compilation and distribution
3361 environment to support the new autoconf 2.52. That version is
3362 now required to compile the CVS trunk.
3364 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3366 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3367 to generally parse user@fqdn format strings. Affected file
3368 lib/silcutil/silcutil.c.
3370 * Added nickname_format and nickname_force_format fields to the
3371 SilcClientParams structure. The first one defines the format
3372 for the nicknames that the library will enforce if the receives
3373 multiple same nicknames. The second one is boolean value and
3374 can be used to force the library to always enforce the format
3375 to the nicknames regardles whether there are multiple nicknames
3376 or not. This configurable formatting was employed to flexibly
3377 support accessing multiple nicknames from the user interface.
3378 The userinterface can now set the nicknames to what ever format
3379 they prefer. Affected file lib/silcclient/silcapi.h.
3381 Added function silc_client_nickname_format to the file
3382 lib/silcclient/idlist.c. It performs the nickname formatting.
3384 Added new field `hostname´ to the SilcClientEntry context.
3385 It holds the hostname of the client. Affected file is
3386 lib/silcclient/idlist.h.
3388 * Irssi SILC Client sets the nicknames in nick@hostn format.
3389 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3390 irssi/src/silc/core/silc-core.c.
3392 The WHOIS printing now also shows both the real nickname and
3393 the formatted nickname so that user knows how to access the
3394 user if there are multiple same nicknames cached. Affected
3395 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3396 printing formatting too to take the hostname now as a separate
3397 argument. The Affected file is
3398 irssi/src/fe-common/silc/modules-formats.[ch].
3400 * Changed the silc_client_get_clients_local to accept the formatted
3401 nickname as argument. It accepts the real nickname too but the
3402 formatted nickname can be used to find the true entry from
3403 multiple entries. Affected file lib/silcclient/silcapi.h and
3404 lib/silcclient/idlist.c.
3406 * Added nickname_format_parse field to the SilcClientParams.
3407 It is a callback function provided by the application to parse
3408 the nickname out of the formatted nickname string. The library
3409 calls it to get the nickname from the formatted string. Since
3410 the application generally knows better the format of the nickname
3411 string it parses it instead of the library, even though library
3412 encodes the formatted string. If the callback function is not
3413 provided then the library will use the string as is. The
3414 affected file is lib/silcclient/silcapi.h.
3416 * All the nickname strings passed to the client library in
3417 commands are now expected to be formatted nickname strings.
3418 If the command does not support the formatted nickname string
3419 it will assume that the sent string is the actual nickname.
3420 Affected file lib/silcclient/command.c.
3422 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3424 * Added public key authentication support to OPER and SILCOPER
3425 commands in the client library. Affected file is
3426 lib/silcclient/command.c.
3428 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Changed the get_auth_methdod client operation to be asynchronous.
3431 It can be async if the application resolves the authentication
3432 method from the server during the negotiation. Added new
3433 SilcGetAuthMeth completion callback that the application will
3434 call after resolving the authentication method.
3436 Added function silc_client_request_authentication_method that
3437 the application can use to resolve the authentication method
3438 from the server. Added also SilcConnectionAuthRequest callback
3439 that the library will call after the server has replied. The
3440 application can call this function if it does not know the
3441 current authentication method.
3443 Affected files are lib/silcclient/client.c and
3444 lib/silcclient/silcapi.h.
3446 * The Irssi SILC client now automatically resolves the authentication
3447 method incase any configuration information is not present (and
3448 currently there never is). The affected file is
3449 irssi/src/silc/core/client_ops.c.
3451 * Fixed public key authentication from the client library.
3452 Affected file lib/silcclient/protocol.c. Changed also the
3453 protocol specification about the public key authentication in
3454 the connection authentication protocol. The actual data to be
3455 signed is now computed with a hash function before signing.
3457 * Fixed the public key authentication from the server as well.
3458 Affected file silcd/protocol.c.
3460 * Removed the mlock()'s from the memory allocation routines.
3461 Affected file lib/silcutil/silcmemory.c. The ./configure does
3462 not check anymore for the mlock(). Affected file is
3465 * Fixed USERS command in server to allow the execution of the
3466 command for private and secret channels if the client sending
3467 the command is on the channel. Affected file silcd/command.c.
3469 * Fixed silc_client_get_clients_local to return the clients
3470 count correctly. It could return wrong value. Affected file
3471 lib/silcclient/idlist.c.
3473 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3476 types. The assembler optimizations seemed not to like 64-bit
3477 data types. The assmebler optimizations thus are now enabled
3478 also for BSD systems as opposed to only enable them for Linux.
3480 * Do not check for threads at all on BSD systems. Affected
3481 file configure.in.pre.
3483 * Removed -n and -h options from the Irssi SILC Client since
3484 they are not used in silc.
3486 * Fixed the prime generation to assure that the first digit
3487 of the generated random number is not zero since our conversion
3488 routines does not like number strings that starts with zero
3489 digit. If zero digit is seen the random number is regenerated.
3490 This caused some corrupted RSA keys when the zero first digit
3491 was met. Affected file lib/silcmath/silcprimegen.c.
3493 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Fixed WIN32 configuration in the ./configure script.
3496 Fixed to include xti.h on environments that has it.
3497 Patches by Carsten Ilchmann and andrew.
3499 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Changed the silc_id_create_client_id to be collision
3502 resistant. It is now assured that there cannot be created
3503 two same client ID's. I suspect that some weird bugs in
3504 the server were actually caused by duplicate Client IDs.
3505 Affected file silcd/serverid.[ch]. A router receiving
3506 new ID now also assures and informs the sending server
3507 if the ID caused collision.
3509 * Changed the silc_id_create_channel_id to also assure that
3510 there are no collisions.
3512 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Statement about ignoring the Mutual Authentication flag when
3515 performing rekey with PFS was a bit misleading. It is ignored
3516 if it was set in the initial negotiation, it cannot be even
3517 set in the rekey. Fixed in the ke-auth draft. Started the
3518 new versions of the protocol drafts in the doc/.
3520 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3522 * Fixed a bug in silc_client_command_identify_save when saving
3523 new channel information. The channel name was no duplicated
3524 and caused crash on exit. Affected file is
3525 lib/silcclient/command_reply.c.
3527 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * Fixed the getkey command handling in the server. Send just
3530 empty OK reply to the sender if the key could not be fetched
3531 (but everything else was ok, like the key just was not available).
3532 Changed the public key parameter to optional in the protocol
3533 specs so that empty OK reply can be sent. Affected file
3536 Added a message to Irssi SILC client to tell to user if the
3537 server did not return a public key.
3539 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Fixed a channel key regeneration bug. It registered new
3542 timeout tasks exponentially until all system resources were
3543 used. Affected file silcd/server.c.
3545 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3547 * Added the SILC Document generator to the scripts/silcdoc.
3548 It can be used to generate the Toolkit Reference Manual out
3549 of the source tree. Internally it will also use the RoboDoc
3550 generator now imported in util/robodoc.
3552 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Added couple of return's in rekey protocol if error orccurred
3555 during the protocol. The execution must be terminated.
3556 Affected file silcd/protocol.c. Also, terminate the protocol
3557 always with timeout.
3559 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3561 * The client's Client ID was created initally from the wrong
3562 nickname (it could have been in format nick@host) in the
3563 silc_server_new_client. Affected file silcd/packet_receive.c
3565 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Added some SILC_LOG_ERROR's to various error conditions
3568 if client could not be added to ID cache. Affected files
3569 silcd/packet_receive.c and silcd/server.c.
3571 * When client's sock->user_data is freed, NULL also the
3572 client->router and client->connection pointers. Added check
3573 for these pointers being NULL to various places around the
3574 code. Affected file silcd/server.c.
3576 * Added client->data.registered == TRUE checks to various
3577 places around the code to assure that unregistered client's
3578 are not handled when it is not allowed. Affected file
3581 * Added `bool registered' fields to all
3582 silc_idlist_[server|client]_get_* routines to indicate whether
3583 the fetched client needs to be registered or not. Affected
3584 file silcd/idlist.[ch].
3586 * Add your own entry as registered to the ID cache in the
3587 server. Affected file server.c.
3589 * Fixed a bug in silc_server_new_server. The SilcServer was
3590 set as the new server's context instead of SilcServerEntry.
3591 This naturally caused some weird bugs.
3593 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Do not delete the channel rekey task when adding it
3596 for in silc_server_create_channel_key.
3598 * Changed the silc_server_create_channel_key to return
3599 TRUE or FALSE to indicate the success of the channel key
3602 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Fixed MSVC++ project files and added missing files to
3605 Makefiles under win32/.
3607 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3609 * Do not add TCP_NODELAY flag if the operating system
3610 does not have it defined. Affected files are
3611 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3613 * Fixed buffer overflow from Irssi SILC Client. Affected
3614 file irssi/src/fe-common/core/themes.c.
3616 * Fixed double free in client library in the file
3617 lib/silcclient/client.c when disconnecting from server.
3619 * Applied double free patch from cras to Irssi SILC client.
3620 Affected files irssi/src/core/[modules/expandos].c
3622 * Fixed the disconnection handling to Irssi SILC Client.
3623 The application must call silc_client_close_connection
3624 in ops->connect client operation in case of failure of
3625 the connection. Affected file is
3626 irssi/src/silc/core/client_ops.c.
3628 * Do not set sock->protocol to NULL in the function
3629 silc_client_close_connection after executing the protocol's
3630 final callback since the sock might not be valid anymore.
3631 Affected file lib/silcclient/client.c.
3633 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Do not enable SILC_THREADS if the linking with libpthread
3636 did not happen. Affected file configure.in.pre.
3638 * Added notion to protocol specification that server must
3639 verify the sent authentication payload with CMODE when
3640 setting the channel founder key. Implemented it to the
3641 server. Affected file silcd/command.c.
3643 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3645 * Added _EXTRA_DIST SILC distribution variable to the
3646 distributions file. It is used to conditionally add extra
3647 files or directories to the specific distribution. Affected
3648 files ./prepare, Makefile.am.pre and distributions.
3650 Removed the `_' from the start of the distribution names.
3653 * Added README.WIN32 for instructions to compile the Toolkit
3656 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * Fixed a double free in disconnection in the server. Affected
3659 file is silcd/server.c.
3661 * Fixed the lib/silcske/groups.c to work now also with GMP
3662 MP library. The string conversion did not work when using
3663 specific base and the base is indicated in the string as well.
3665 * Created win32/ directory which now includes MSVC++ specific
3666 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3667 It will appear only in the toolkit distribution
3669 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3671 * Changed the key material distribution function in case when
3672 the hash output is too short. The data is now concatenated
3673 a bit differently than it used to. Made the change to the
3674 SKE protocol specification.
3676 * Added better GMP detection to configure.in.pre. A patch
3679 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3681 * Fixed a minor bug in SKE that might cause some problem on
3682 some platforms. Affected file lib/silcske/silcske.c.
3684 * Added the cookie checking for initiator in the SKE. It checks
3685 that the responder returns the sent cookie unmodified. The
3686 affected file is lib/silcske/silcske.c. Added new SKE
3687 error type INVALID_COOKIE that can be sent during the
3688 negotiation. Fixed some memory leaks as well.
3690 * Added the "invalid cookie" error message to Irssi SILC client's
3693 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3695 * Added `task_max' field to the SilcClientParams to indicate
3696 the maximum tasks the scheduler can handle. If set to zero,
3697 default values are used. Affected file lib/silcclient/silcapi.h.
3699 * Fixed memory leaks in silc_client_close_connection. Affected
3700 file lib/silcclient/client.c.
3702 * Added silc_client_del_client_entry to client library to free
3703 all memory of given client entry. Affected file is
3704 lib/silcclient/idlist.[ch].
3706 * Added new functions silc_client_del_channel and
3707 silc_client_del_server to delete channel and server entries.
3708 Affected file lib/silcclient/[silcapi.h/idlist.c].
3710 * Removed silc_client_del_client_by_id from silcapi.h.
3712 * Fixed the INFO command to return the server's own info
3713 correctly when querying by Server ID. Affected file is
3716 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3718 * Removed the non-blocking settings in WIN32 code in the
3719 silc_sock_[read/write] and added SleepEx instead. Affected
3720 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3721 of input data is now checked with FIONREAD and ioctlsocket.
3723 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3725 * Call silc_schedule_task_del_by_context in the
3726 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3727 Affected file lib/silccore/silcprotocol.c.
3729 * Call silc_protocol_cancel for active protocols in the
3730 silc_server_close_connection if the funtion
3731 silc_server_free_sock_user_data has not been called.
3732 Affected file silcd/server.c.
3734 * Generic tasks cannot be deleted using the del_by_fd
3735 task deleting function since generic tasks does not match
3736 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3738 * Added a notion to SILCOPER help file that the SILCOPER works
3739 only on router server, not on normal server.
3741 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3743 * Added for WIN32 support for the new scheduler as well.
3744 Affected file lib/silcutil/win32/silcwin32schedule.c.
3746 * Fixed the SHA1 implementation to work on various platforms.
3748 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3750 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3751 API. It is part of the scheduler now. Everything else is
3752 as previously but some functions has changed their names.
3753 Checkout the lib/silcutil/silcschedule.h for the interface.
3754 Updated all applications to use the new interface. Affected
3755 files are lib/silcutil/silcschedule.[ch].
3757 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Found a bug in the SKE implementation. The HASH value,
3760 specified by the protocol, was not computed correctly. The
3761 public key of the responder was not added to the computation
3762 even though it is mandatory. Affected file lib/silcske/silcske.c.
3763 This unfortunately causes incompatibilities with older
3764 clients and servers.
3766 * Added WIN32 specific network init and uninit functions:
3767 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3768 the Winsock2. Affected file lib/silcutil/silcnet.h and
3769 lib/silcutil/win32/silcwin32net.c.
3771 * Set the socket always to nonblocking mode on WIN32 after
3772 reading data or writing data. Affected file is
3773 lib/silcutil/win32/silcwin32sockconn.c.
3775 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Fixed various compilation problems under WIN32. Affected
3778 files lib/silcutil/win32/silcwin32thread.c and
3779 lib/silcutil/win32/silcwin32schedule.c.
3781 * Removed all _internal.h #includes from public header
3782 files. Internal headers must never be included from
3785 Removed also the lib/silcske/payload_internal.h file.
3787 * All include files that may be needed (public and some others
3788 included by the public headers) by application developers are
3789 now copied to the ./includes directory. It does not copy any
3790 internal headers. Affected file Makefile.defines.pre and all
3791 Makefile.am's under lib/ and subdirs.
3793 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3795 * Do not change the ~/.silc directory's permissions automatically.
3796 Affected file irssi/src/silc/core/clientutil.c.
3798 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Do not cancel the protocol in silc_server_close_connection
3801 it might cause recursion. Now cancelled in the function
3802 silc_server_free_sock_user_data. Affected file silcd/server.c.
3804 * Fixed the silc_server_remove_clients_by_server to regenerate
3805 the channel keys correctly finally. Added also new function
3806 silc_server_remove_clients_channels to actually do it.
3807 Affected file silcd/server.c.
3809 * Fixed the silc_server_new_channel to not crash by giving
3810 wrong router to the new channel. Affected file is
3811 silcd/packet_receive.c.
3813 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3816 which is given as argument to the silc_client_alloc now.
3817 It can be used to configure the client and set various parameters
3818 that affect the function of the client.
3820 * The USERS command in server did not check whether the channel
3821 is private or secret. Affected file silcd/command.c.
3823 * Added new argument to the USERS command in protocol specification.
3824 The USERS command now can take the channel name as argument
3825 as well. Added support for this in client and server and
3826 updated the protocol specs.
3828 * Completed the GETKEY command in client. It can be now used
3829 to fetch also servers public key not only some clients.
3830 Affected files lib/silcclient/command[_reply].c.
3832 * Added silc_client_get_server to return server entry by the
3833 server name. Affected files lib/silcclient/silcapi.h and
3836 * Redefined the IDENTIFY command in protocol specification to be
3837 more generic. It now can be used to query information about
3838 any entity in the SILC Network, including clients, servers and
3839 channels. The query may be based either the entity's name
3840 or the ID. Added support for this in both client and server.
3842 Affected files silcd/command.c and lib/silcclient/command.c
3843 and command_reply.c.
3845 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3846 the _from_client and _from_server functions. Affected file
3849 * Added silc_client_get_channel_by_id_resolve to the file
3850 lib/silcclient/silcapi.h to resolve channel information by
3851 its ID. Added also silc_client_get_channel_by_id that
3852 does not resolve it from the server.
3854 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Added SilcServerEntry context into the client library
3857 to represent one server. The INFO command now allocates
3858 these to save the resolved server info. For now on the
3859 client library will also keep information about servers,
3860 connected and resolved with INFO.
3862 The INFO command now allocates the SilcServerEntry context
3863 and saves the server info there. The COMMAND_REPLY in
3864 the INFO now returns the parameters to application in
3865 same order as defined in the protocol specification.
3867 The entries are cached in the client->server_cache.
3869 * The INFO command is now issued after received the Client ID
3870 from the server. Affected file lib/silcclient/client.c.
3872 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3873 to the application as the mode changer might be server.
3874 It is guaranteed that NULL is not returned anymore to the
3875 application. Affected file lib/silcclient/client_notify.c.
3877 The ID Type is now also passed to the application so that
3878 it can check whether the returned entry is SilcClientEntry
3881 Added new function silc_client_get_server_by_id to return
3882 the server entry by ID. Affected files are the
3883 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3885 * Do not create the channel in the Irssi SILC Client when issuing
3886 the JOIN command but when received the sucessful JOIN command
3887 reply. Otherwise the channel might get created even though we
3888 could not join it. The Affected file is
3889 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3891 * Fixed a channel joining bug in router. The router must also
3892 check the channel modes, invite and ban lists etc. when serving
3893 the JOIN command sent by normal server. Affected file is
3894 silcd/command.c. The router now resolves the client's
3895 information from the server who sent the JOIN command if it
3896 does not know it, and processes the JOIN command only after
3899 * Changed the SilcCommandCb to take new argument; void *context2.
3900 Affected file lib/silccore/silccommand.h
3902 The second argument in the command callbacks in the server now
3903 includes the SilcServerCommandReplyContext if the command was
3904 called as pending command callback from the command reply.
3905 Otherwise it is NULL. When called as pending the status of the
3906 command reply will be checked and if it was erronous the
3907 error will be sent to the original sender of the command.
3908 This way the client always receives the error messages even
3909 though the server was actually the one who received the error
3910 when it resent the command to router, for example. Affected
3911 files silcd/command[_reply].[ch].
3913 * Fixed sending WHOWAS command's error message to client if
3914 the requested client could not be found. It was missing.
3917 * Changed the CMODE and CUMODE commands reply arguments in the
3918 protocol specification. The Channel ID is now sent in both
3919 of the commands to identify the channel. Implemented this
3920 new feature to the client and server. Affected files
3921 lib/silcclient/command_reply.c and silcd/command.c.
3923 * Made better checks for invite and ban lists in the JOIN
3924 command in server. Affected file silcd/command.c.
3926 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3928 * The server now performs the incoming host IP/DNS lookup
3929 using the silc_socket_host_lookup and thus does not block
3930 the server anymore. Affected file silcd/server.c.
3932 * Completed the multi-thread support for SILC Scheduler in
3933 the lib/silcutil/silcschedule.c.
3935 * Fixed the configure.in.pre to detect the pthread correctly
3938 * Fixed a deadlock in silc_task_queue_wakeup in the file
3939 lib/silcutil/silctask.c.
3941 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3943 * Added new function silc_schedule_wakeup that is used in
3944 multi-threaded environment to wakeup the main thread's
3945 schduler. It needs to be used when a thread adds a new task
3946 or removes a task from task queues. After waking up, the
3947 scheduler will detect the task queue changes. If threads
3948 support is not compiled in this function has no effect.
3949 Implemented the wakeup mechanism to both Unix and WIN32
3950 systems. Affected files are lib/silcutil/silcschedule.[ch],
3951 lib/silcutil/unix/silcunixschedule.c and the
3952 lib/silcutil/win32/silcwin32schedule.c.
3954 * Added new function silc_task_queue_wakeup to wakeup the
3955 scheduler by the specified task queue. Affected file
3956 lib/silcutil/silctask.[ch].
3958 * The silc_socket_host_lookup_start now wakes up the scheduler
3959 after adding the timeout task. Affected file is
3960 lib/silcutil/silcsockconn.c.
3962 * The silc_socket_host_lookup is synchronous now if the threads
3963 support is not compiled in. However, the callback is still
3964 called asyncronously through the scheduler, anyway. Affected
3965 file lib/silcutil/silcsockconn.c.
3967 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3969 * Added new function silc_socket_host_lookup to perform
3970 asynchronous IP and FQDN lookups for the socket connection.
3971 Affected files lib/silcutil/silcsockconn.[ch].
3973 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3975 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3976 that may or may not compile the mutex support in.
3978 Changed the silc_mutex_alloc interface. It allocates the
3979 mutex now to the sent pointer and returns TRUE or FALSE.
3981 Affected file lib/silcutil/silcmutex.h.
3983 * Wrote the SILC Task Queue interface to support multi-threads.
3984 Affected file lib/silcutil/silctask.[ch].
3986 * Wrote the SILC Scheduler to support multi-threads. Affected
3987 file lib/silcutil/silcschedule.c.
3989 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3992 in lib/silcutil/win32/.
3994 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3996 * Defined SILC Mutex API and SILC Thread API and implemented
3997 them for Unix. Affected files are
3998 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3999 lib/silcutil/unix/silcunixmutex.c and
4000 lib/silcutil/unix/silcunixthread.c.
4002 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4004 * Fixed the silc_server_remove_clients_by_server's channel
4005 key re-generation. The hash table handling was incorrect
4006 and would not work with many channels. Affected file is
4009 * Fixed some memory leaks around the server code.
4011 * Rewrote the silc_server_get_users_on_channel to support IPv6
4012 based Client ID's. Affected file silcd/server.c.
4014 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4015 specification. However, a separate document must be written
4016 to define the detailed signing procedure and the payload
4017 associated with the flag. Defined the flag to the
4018 lib/silccore/silcchannel.h as well.
4020 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4022 * Changed the dynamic tables to static size tables in the
4023 lib/silccrypt/silchmac.c.
4025 * Removed GCC dependencies from the code. A patch by cras.
4027 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4029 * Do not show the error "Error receiving packet bla bla"
4030 in server if it really was not an error (-2 means that reading
4031 is pending). Affected file silcd/server.c.
4033 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Fixed a possible crash in silc_server_remove_clients_by_server
4036 in silcd/server.c. Fixed there also some memory leaks.
4038 * Fixed the silc_idlist_replace_client_id. It could replace
4039 wrong key in the hash table. Affected file silcd/idlist.c.
4041 * Do not check whether there are global users on the channel
4042 if the channel->global_users is FALSE. Affected functions
4043 silc_server_remove_from_one_channel and
4044 silc_server_remove_from_channels in silcd/server.c. Also,
4045 do not check if the removed client is local as we can be
4046 sure that global client was not removed from the channel
4047 and checking for global users is not needed.
4049 * The silc_server_remove_clients_by_server now re-generates
4050 the channel keys correctly for those channels that had
4051 clients removed from them. Affected file silcd/server.c.
4053 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4055 * Found the reason of random crashes in the server. We weren't
4056 ignoring the SIGPIPE signal (which can be sent in write())
4057 and it crashed the server. Affected file silcd/silcd.c.
4059 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Assure that sock->user_data is not NULL in the function
4062 silc_server_packet_send in silcd/packet_send.c.
4064 * Disconnect the remote connection if it could not be added
4065 to any ID lists in the server. The affected file is
4068 * Check in silc_server_packet_send[_real/dest] that the
4069 socket is not disconnecting and ignore the data if it is.
4070 Affected file silcd/packet_send.c.
4072 * Define inline to __inline on native WIN32 compilation.
4073 Affected file includes/silcwin32.h.
4075 * Added some explicit type casts for inline code since MSVC
4076 require them. Affected files lib/silcutil/silcbuffer.h,
4077 lib/trq/silcdlist.h and lib/trq/silclist.h.
4079 * Print warning in log files from now on if the packet
4080 decryption fails. Affected file silcd/server.c.
4082 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4084 * Changed the `say' client operation's interface to accept
4085 new `type' argument to indicate the type of the message sent
4086 by the library. The application may filter the library's
4087 messages according the type. The affected file is the
4088 lib/silcclient/silcapi.h.
4090 * Added two new functions to lib/silcclient/silcapi.h:
4091 silc_client_del_client and silc_client_del_client_by_id.
4092 Affected file lib/silcclient/idlist.c.
4094 * Moved the clientincludes.h from includes/ to silc/ and
4095 serverincludes.h from includes/ to silcd/.
4097 * The modes for the CMODE and CUMODE are now passed as
4098 uint32 for application with COMMAND_REPLY. The affected
4099 file is lib/silcclient/command_reply.c.
4101 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4103 * /WHOIS without arguments shows client's own information.
4104 Affected file lib/silcclient/command.c.
4106 * Changed PING to not accept any arguments. The specs
4107 says that client can ping only the connected server so
4108 requiring an argument is not needed. Affected file is
4109 lib/silcclient/command.c.
4111 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4113 * Fixed a fatal bug in private message sending and reception
4114 encryption and decryption when using private message keys.
4115 The implementation was incorrect and did not follow the
4116 specification. It causd that some of the message were
4117 lost since it did not use the sending and receiving keys
4118 as the protocol suggests. This has been fixed and will cause
4119 incompatibilities with older clients when sending private
4120 message encrypted with private message keys. Affected files
4121 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4122 and various other in Irssi SILC Client.
4124 Added `responder' boolean argument to the functions
4125 silc_client_add_private_message_key[_ske] to indicate when
4126 the key is added as responder or initiator of the key
4129 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4131 * Removed the silc_ske_check_version function and created
4132 a SilcSKECheckVersion callback. Added also a function
4133 silc_ske_set_callbacks that is now used to set all SKE
4134 callbacks. The callback functions are not given to
4135 the SKE functions anymore, but this function is used to
4138 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4140 * Added `silc_version' argument to the silc_client_alloc
4141 to define the version of the application for the library.
4142 The library will use the version string to compare it
4143 against the remote host's (usually a server) version
4144 string. Affected file lib/silcclient/silcapi.h
4146 * Added the KE protocol context to Key Agreement context
4147 in client library so that we can abort the SKE if it
4148 is in process when we get timeout. Affected file is
4149 lib/silcclient/client_keyagr.c.
4151 * Do not resolve the client ID forever if it returns in the
4152 first time that such client does not exist. This was done
4153 for example with private message. Affected file is
4154 lib/silcclient/client_prvmsg.c.
4156 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4158 * Do not add regex.h for WIN32. The affected file
4159 includes/silcincludes.h.
4161 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4162 not work yet 100%. It generates the DLL's automatically
4163 when compiling with --with-win32 under cygwin.
4165 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4167 * lib/contrib/regex.c is not compiled on WIN32.
4169 * Added silc_net_get_socket_opt function to the
4170 lib/silcutil/silcnet.h.
4172 * Added includes/silcwin32.h for WIN32 specific includes
4175 * Do not use ptime structure or any of the posix process
4176 functions on WIN32 in lib/silccrypt/silrng.c.
4178 * Added silc_gettimeofday to provide generic function
4179 for struct timeval on all platforms. Added the function
4180 to lib/silcutil/silcutil.h.
4182 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4184 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4185 library as they clearly belong there. As a plus side we
4186 can make the actual socket connection routines platform
4189 Added also new generic function silc_socket_read and
4190 silc_socket_write (that used to be silc_packet_[read/write].
4191 The implementation of these are platform specific.
4193 * Added WIN32 specific routines of silc_socket_[read/write]
4194 to lib/silcutil/win32/silcwin32sockconn.c.
4196 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4198 * Added preliminary support for native WIN32 compilation under
4199 cygwin (using the -mno-cygwin option for GCC) to the
4200 ./configure.in.pre. The --with-win32 now prepares the
4201 compilation for native WIN32.
4203 * Rewrote the SILC Scheduler interface in the file
4204 lib/silcutil/silcschedule.h. The scheduler is now context
4205 based and does not have anymore any global static scheduler.
4206 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4207 and created lib/silcutil/win32 directory for WIN32 based
4210 * Added Unix specific network routines to the
4211 lib/silcutil/unix/silcunixnet.c and the old
4212 lib/silcutil/silcnet.c includes now only generic routines.
4214 Added WIN32 specific network routines to the
4215 lib/silcutil/win32/silcwin32net.c.
4217 * Added Unix specific utility functions from the
4218 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4220 * Added WIN32 SILC Scheduler to the file
4221 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4224 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4226 * Do not handle JOIN notify in the server if the target client
4227 is not registered (idata->registered == FALSE). The affected
4228 file is silcd/packet_receive.c.
4230 * Update the nickrec->founder in event_cumode in the Irssi SILC
4231 client. Affected file irssi/src/silc/core/silc-channels.c.
4233 * Fixed the CUMODE_CHANGE notify handling in the server when
4234 server and router are announcing their clients on channels.
4235 Now the mode changes are saved and notified correctly. The
4236 affected file is /silcd/packet_receive.c.
4238 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4239 They really did not replace the cache entry in the ID Cache.
4240 Now they do that. Affected file silcd/idlist.c.
4242 * Fixed the KICK notify handling in the Irssi SILC client to
4243 update the channel records so that the kicked client does not
4244 appear to be on the channel. The affected file is
4245 irssi/src/silc/core/silc-channels.c.
4247 * Always update the conn->current_channel when executing command
4248 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4250 * Fixed the KILL notify handling in Irssi SILC client to remove
4251 the killed client on all channels.
4253 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Fixed the silc_parse_command_line to remove extra spaces
4256 from the start and end of the arguments. Affected file is
4257 lib/silcutil/silcutil.c.
4259 * Cancel and free any active protocol in the function
4260 silc_server_close_connection. Affected file silcd/server.c.
4262 * Cancel and free any active protocol in the function
4263 silc_client_close_connction. Affected file is
4264 lib/silcclient/client.c.
4266 * Do not execute the KILL command for clients that are in
4267 history (ie. they are not in the network). Affected file is
4270 * Fixed KILL notify handling, client does not crash anymore.
4271 Affected file irssi/src/silc/core/silc-channels.c.
4273 * Reduced the default packet buffer size from 2048 to 1024 in
4274 lib/silccore/silcpacket.c.
4276 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4277 counter to the SKE context that is incresed when the SKE library
4278 performs async operation outside the library. If the outside
4279 process frees the SKE context and FREED status will be set
4280 and the library will detect after the sync operation that the
4281 libary is freed. The affected files are
4282 lib/silcske/silcske[_status].[ch].
4284 * Resolve the client entry information in the function
4285 silc_client_channel_message to assure that NULL pointer is not
4286 passed as client entry to the application. */
4288 * Fixed the task timeout calculation to assure that there is
4289 never negative timeouts. The affected file is
4290 lib/silcutil/silcschedule.c.
4292 * Fixed the channel user mode notification sending in server.
4293 It was sent point-to-point to the router (or to server by router)
4294 but it needs to be destined to a channel. The routines now
4295 supports sending the channel user mode notifys to the channels
4296 when announcing clients and channels. Affected files are
4297 silcd/server.c and silcd/packet_receive.c.
4299 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4300 It did not actually replace the old channel entry in the cache.
4301 Affected file lib/silcclient/client_notify.c.
4303 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Fixed a possible crash in silc_packet_send_prepare. It now
4306 assures always that there is enough space in the buffer and
4307 at the tail area of the buffer (for MAC).
4309 Fixed the inbound buffer reallocation in silc_packet_read.
4310 It was old code and did not handle the reallocation correctly.
4313 The affected file is lib/silccore/silcpacket.c.
4315 * Fixed buffer overflow in silc_parse_nickname in the file
4316 lib/silcutil/silcutil.c.
4318 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4320 * make install generates new server keys only if there is not
4323 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4326 Added check that if the NOREPLY is set then we will not send
4327 the away message. This avoids infinite loop of away messages
4328 if both clients are away. The affected file is
4329 lib/silcclient/client_prvmsg.c.
4331 * Fixed client crash if /NICK was given without arguments.
4332 Affected file lib/silcclient/command.c.
4334 * Server does not send the invite list in INVITE command back
4335 to the client if the list was not altered. Added this notion
4336 to the protocol spec as well. Affected file silcd/command.c.
4338 Fixed possible crash in INVITE command by checking the
4339 value of silc_server_get_client_route command.
4341 * Fixed the INVITE notify type handling. The arguments are now
4342 taken in correct order and client does not crash. The affected
4343 file is irssi/src/silc/core/silc-channels.c.
4345 Removed the "Inviting xxx to channel" message from the
4346 client library away and let the application handle it.
4347 Affected file lib/silcclient/command.c. Added that message
4348 to Irssi SILC client's message formats.
4350 * Fixed CMODE command crash in client. It now checks the
4351 amount of arguments correctly and does not crash. The affected
4352 file is lib/silcclient/command.c.
4354 * Do not create new channel automatically in silc_channels_join
4355 but check whether the channel by that name already exists.
4356 Affected file irssi/silc/core/silc-channels.c.
4358 * Do not send the SERVER_SIGNOFF to router if the disconnected
4359 entity was the router. Affected file silcd/server.c.
4361 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4362 SILC client as it was missing from there.
4364 Added the handling of the KICK notify to the Irssi SILC client
4365 as it was missing. Added "you have been kicked" message to
4366 Irssi SILC client's message modules formats.
4368 Added the handing of the KILL notify to the Irssi SILC client
4369 as it was missing. Added the kill message module formats
4372 The affected file is irssi/src/silc/core/silc-channels.c.
4374 * The router did not save the channel mode the server announced.
4375 Affected file silcd/packet_receive.c.
4377 * Fixed a possible crash in INFO command in server. If the
4378 server did not provide the server info it crashed. Affected
4379 file silcd/command.c.
4381 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Fixed the GETKEY command in the server to check also the
4384 global list. Otherwise the GETKEY would not work correctly
4385 in normal SILC server. Affected file silcd/command.c.
4387 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4389 * Fixed GETKEY crash, it crashed if the command did not succseed.
4391 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4393 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4394 is now real and not just an macro interface to GMP.
4396 Removed the entire GMP from the source tree and imported new
4397 NSS MPI library instead. Reason for removing GMP is that it is
4398 extremely large and compiles extremely slow. The NSS MPI
4399 is only a few files and compiles in less than 10 seconds.
4400 The speed is also about the same as GMP. The MPI is imported
4401 to lib/silcmath/mpi.
4403 If the system has GMP installed we will still use the GMP.
4404 If it is not then the NSS MPI will be compiled.
4406 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Merged a long nickname (127 characters long) crash bugfix from
4409 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4411 * Merged a freed memory reference bugfix from Irssi CVS tree.
4412 Affected file irssi/src/core/commands.c.
4414 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added the server's public key sving and verification to the
4417 server when performing the SKE. This was missing and the
4418 remote server's (or router's) public key was accepted without
4419 checking whether we have it previously or trust it at all.
4420 Affected file silcd/protocol.c.
4422 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Check in the silc_server_timeout_remote if protocol is active
4425 and make sure that the protocol's final callback is called so
4426 that all memory if freed. Affected file silcd/server.c.
4428 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * silc_server_whois_send_reply crashed the server if the nickname
4431 was 127 characters long. Affected file silcd/command.c.
4433 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Added sanity check to the silc_server_new_client. If the hostname
4436 is provided inside username then check that the provided hostname
4437 really is the same as the resolved one. If the hostname was not
4438 resolved then check it from the public key. Affected file is
4439 silcd/packet_receive.c.
4441 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4442 if the server disconnected us and the connection is not valid
4443 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4445 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4446 the library to the lib/silcutil/silcutil.[ch].
4448 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Close log file after open. Affected file
4451 lib/silcutil/silclog.c.
4453 * Check whether sock == NULL in silc_client_send_packet and return
4454 if it is. Affected file lib/silcclient/silcclient.c.
4456 * Check rec->entry == NULL in the Irssi SILC Client before
4457 sending the channel message. Affecte file is
4458 irssi/src/silc/core/silc-servers.c.
4460 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4462 * Merged a splitted window bugfix from Irssi CVS tree. The
4463 affected file is irssi/src/fe-text/textbuffer-view.c.
4465 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4466 It did not print nickname.
4468 * Improved the distributions system a bit.
4470 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4473 irssi/src/fe-text/gui-window.c.
4475 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4476 to in-active server. The affected file is
4477 irssi/src/silc/core/client_ops.c.
4479 * Resolve the client in USERS command reply if the entry does
4480 not have username resolved. The affected file is
4481 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4482 command to WHOIS command to really resolve stuff. The USERS
4483 is not used any more in any critical section so WHOIS can
4484 be used even though it might be slower than IDENTIFY.
4486 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4489 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4491 * Changed the protocol API a bit more consistent in the
4492 lib/silccore/silcprotocol.[ch].
4494 * Changed the following headers to ROBODoc format:
4496 lib/silccore/silcpayload.h
4497 lib/silccore/silcprotocol.h
4498 lib/silccore/silcsockconn.h
4500 All core library headers are now formatted.
4502 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Fixed a bug in Irssi SILC client; do not show that you are
4505 server/router operator if you really are not. Affected file is
4506 irssi/src/silc/core/client_ops.c.
4508 * Renamed silc_command_free_payload to silc_command_payload_free.
4509 Affected file lib/silccore/silccommand.h
4511 * Added silcmath.h to include the prototoypes of various routines
4512 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4515 * Changed the following headers to ROBODoc format:
4517 lib/silccore/silcchannel.h
4518 lib/silccore/silccommand.h
4519 lib/silccore/silcid.h
4520 lib/silccore/silcidcache.h
4521 lib/silccore/silcmode.h
4522 lib/silccore/silcnotify.h
4523 lib/silccore/silcpacket.h
4524 lib/silcmath/silcmath.h
4526 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4528 * Added checking to the server code not to start the server if
4529 ciphers and stuff are not configured properly. Affected files
4530 silcd/serverconfig.[h] and silcd/server.c.
4532 * Changed the layout of the header files of the public interfaces
4533 in the SILC libraries. The new layout supports ROBODoc
4534 documentation tool (and some others) so that it is easy to create
4535 a library reference manual. All the other headers and source
4536 code must still follow the CodingStyle document. Also source
4537 code must not include these ROBODoc stuffs, only the headers.
4538 Furthermore, all public interface headers must now be named
4539 by using `silc' prefix, example: silcapi.h, silccipher.h.
4540 Some files were renamed due to this. All the other headers
4541 must not be used as public interfaces. I will update the
4542 CodingStyle document later. Changed following headers, so far:
4544 lib/silcclient/silcapi.h
4545 lib/silccore/silcauth.h
4546 lib/silccore/silcprivate.h
4547 lib/silccrypt/silcdh.h
4549 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Removed silc_client_packet_send_flush from the client library
4554 as it is not needed. Affected file lib/silcclient/client.[ch].
4556 * Added printing of message of unresolved authentication method
4557 to the Irssi SILC client. Added it to the module formats.
4558 Removed the same message from the client library.
4560 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Added new distribution feature, DISTLABEL. Every distribution
4563 can define own preprocessor label that can be used in the
4564 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4565 file distributions, acconfig.h.pre and prepare.
4567 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Added Makefile.defines_int to include the actual definitions
4570 for Makefile.defines.in. Tested the new distribution system,
4571 created distributions and tested installation.
4573 * Added AWAY message printing to the Irssi SILC client. Added
4574 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4576 * Added SCONNECT command to call the SILC's CONNECT command.
4577 Cannot use CONNECT directly since Irssi uses that internally.
4578 Affected file irssi/src/silc/core/silc-servers.c.
4580 Added ACTION local command. It is same as ME command but takes
4581 the channel as mandatory argument.
4583 Rewrote some of the Irssi's help files to suite for SILC
4586 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Added Makefile.defines[.in] that should for now on be included
4589 in all Makefile.am file in the source tree. That file includes
4590 all common compilation definitions for SILC source tree.
4592 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Minor changes to the ./prepare script to change the package
4595 name according the distribution name to the configure.in.
4597 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Created new distribution system. Added file `distributions'
4600 that defines all the distributions that can be created out of
4601 the SILC source tree. The ./prepare script now reads that
4602 file to determine how to prepare the distributions. The
4603 first argument to the ./prepare is the name of the distribution
4604 and second is the version of the distribution. If given
4605 without arguments it creates the default (toolkit) distribution
4606 with the default version (defined in ./prepare).
4608 All Makefile.am files that are subject to the distributions
4609 are now named as Makefile.am.pre. These are ./Makefile.am
4610 and lib/Makefile.am. Others may be changed later.
4612 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Added invite list, ban list, some key management and connection
4615 error message printing to module formats in the Irssi SILC client.
4617 * Added new silc_client_set_away_message to set the away message
4618 that is back to the person who sent private message. The
4619 affected file lib/silcclient/silcapi.h and the
4620 lib/silcclient/client_prvmsg.c.
4622 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4624 * Fixed the private message sending in the Irssi SILC client,
4625 added local command KEY to the Irssi SILC client.
4627 Added key management and key agreement message formats to the
4628 irssi/src/fe-common/silc/module-formats.[ch].
4630 Added USERS (alias WHO) printing, server/router operator
4631 indication and LIST command printing to the module formats.
4633 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Fixed channel joining notify handling, cumode notify handling
4636 from Irssi SILC client.
4638 * Added SILC specific module-formats to the Irssi SILC client so
4639 that SILC specific message hilighting, colors etc is possible.
4640 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4642 Added channel mode, channel user mode, actions, notices,
4643 whois and whowas printing to the the module-formats.c.
4645 * Fixed a bug in channel deletion in the server. The channel
4646 is not left to the cache even if the channel founder auth mode
4647 is set when there are no users anymore on the channel. Affected
4648 file silcd/server.c.
4650 * The silc_net_localhost now resolves the entire hostname including
4651 the domain name. Affected file lib/silcutil/silcnet.c.
4653 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Changed the ask_passphrase client operation to be ascynchronous.
4656 It has now a completion callback and a context that the
4657 application must call after it has got the passphrase from
4658 the user. Affected files lib/silcclient/silcapi.h,
4659 lib/silcclient/protocol.c, lib/silcclient/command.c and
4662 Added SilcAskPassphrase callback that the application calls
4663 to deliver the passphrase to the library.
4665 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4666 The public key verification and especially a certificate
4667 verification is asynchronous procedure.
4669 Added new SILC_SKE_STATUS_PENDING status to indicate the
4670 request is pending and a callback will be called to finalize
4673 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4674 indicate that remote end did not send its public key (or
4675 certificate), even though we require it. Added check for this
4676 condition in the SKE. This was a security bug, now fixed.
4678 Defined new SilcSKEVerifyCbCompletion callback that is called
4679 when the verification process is completed.
4681 The affected files lib/silcske/silcske_status.h and
4682 lib/silcske/silcske.[ch].
4684 * Changed the verify_public_key client operation to be async
4685 as well. Defined SilcVerifyPublicKey callback that is used to
4686 indicate the success of the public key verification process.
4688 Changed the server and client to use the new async client
4691 * Changed the Irssi SILC client's internal scheduler to be called
4692 twice as many times as it used to be. As a result the client
4693 should be a bit faster now. Affected file is
4694 irssi/src/silc/core/silc-core.c.
4696 * Added support to Irssi SILC client of asynchronous public key
4697 verification and passphrase inquiry. Affected file is
4698 irssi/src/silc/core/silc-core.c.
4700 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Do not say "You have left channel %s" in client library.
4703 Moved it to the application. Affected files are
4704 lib/silcclient/command.c and silc/client_ops.c.
4706 * Fixed silc_client_get_clients. Command context was not
4707 duplicated and was freed memory in the callback. Affected
4708 file lib/silcclient/idlist.c.
4710 * Do not say "you are now talking..." on JOIN command in the
4711 client library. The appliation must handle it.
4713 * Do not say ".. changed topic to" in command reply in the
4714 client libary. The application must handle it.
4716 * Fixed TOPIC command sending in the client library.
4718 * Fixed a memory leak in silc_client_command_free in the file
4719 lib/silcclient/command.c.
4721 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Imported a modified version of Irssi client to the source tree.
4724 The Irssi will be used to create a new client called
4725 Irssi SILC. Imported to irssi/.
4727 Added silc_core_init_finish function to the Irssi. Affected
4728 file irssi/configure.in.
4730 A lot changes in the Makefile.ams around the irssi tree.
4732 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Do not rehash if the new size is same as the old size of the
4735 hash table, in the silc_hash_table_rehash*. The affected file
4736 lib/silcutil/silchashtable.c.
4738 * Replaced hash_table_del_by_context calls from the server
4739 (when channel->user_list and client->channels) to the
4740 hash_table_del as it is sufficient and faster.
4742 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Added silc_hash_table_list, silc_hash_table_get and the
4745 SilcHashTableList structure to provide an alternative way to
4746 traverse the hash table. The affected files are
4747 lib/silcutil/silchashtable.[ch].
4749 * Changed the server's idlist routines to use the hash table
4750 routines to optimize the code.
4752 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Replaced the client entry's `channel' list and channel entry's
4755 `user_list' list to hash tables for optimized lookup. Changed
4756 the code to use the hash table interface around the code.
4757 Affected file lib/silcd/idlist.[ch].
4759 * Added `auto_rehash' boolean argument to the function
4760 silc_hash_table_alloc to indicate whether the hash table should
4761 auto-rehash when it thinks is appropriate time. It will
4762 increase the hash table size if the there is twice as much
4763 entries in the table than the size of the table, and will
4764 decrease the size if there are twice as less entries than
4765 the size of the table.
4767 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4771 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * silc_idcache_purge_by_context deletes the entry now by context
4774 as it is supposed to do. Affected file lib/silccore/idcache.c.
4776 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4777 client is not anymore valid (WHOWAS givens the info) and not
4778 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4780 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Removed the `data' and `data_len' arguments from the ID Cache
4783 interfaces and added `name' argument. ID Cache does not handle
4784 anymore the binary data only a names associated with given ID.
4786 * When hashing a Client ID with silc_hash_id the entire ID is
4787 not hashed anymore, instead only the hash of the Client ID is
4788 hashed. This way we can access the Client ID from the cache
4789 with Client ID but with the hash of the ID (which is a hash of
4790 the nickname) as well without any difference in performance.
4792 Added also silc_idcache_find_by_id_one_ext to do one on one
4793 searching when we have the actual ID. Added also function
4794 silc_hash_client_id_compare. The affected files are
4795 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4797 * When hashing the name associated with a ID it is always done
4798 in lowercase. This way we can access the cache without worrying
4799 about case-sensitivity, even though, for example nicknames are
4802 * Fixed a bug in server with channel message sending. It put
4803 wrong ID type as destination ID. The affected file
4804 silcd/packet_send.c.
4806 * silc_idcache_del_by_context now deletes from all hash tables
4807 by context. Affected file lib/silccore/idcache.c.
4809 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Changed the client library to use the new ID Cache interface.
4812 Changes around the source tree.
4814 * Added silc_hash_table_rehash_ext to rehash with specific
4815 hash function. Affected file lib/silcutil/silchashtable.[ch].
4817 * Added silc_hash_string_compare to compare two strings in the
4818 hash table. Affected file lib/silcutil/silcutil.[ch].
4820 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Added new function silc_idcache_del_by_context into the
4823 lib/silccore/idcache.[ch].
4825 * Changed the server's ID list routines to use the new ID Cache
4826 interface. Changes around the source tree.
4828 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Added silc_hash_table_del[_by_context]_ext functions in to the
4831 lib/silcutil/silchashtable.[ch].
4833 Removed silc_hash_table_find_all* routines and added new
4834 silc_hash_table_find_foreach to replace them.
4836 Added silc_hash_table_replace_ext function as extended
4837 replacing function. Separated the simple hash table interface
4838 from the extended hash table interface in the file
4839 lib/silcutil/silchashtable.h.
4841 * Fixed minor bugs and changed it to use some of the new
4842 hash table functions in lib/silccore/idcache.c
4844 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Added new function silc_hash_table_find_all to return all keys
4847 in the hash table by the specified key. As the hash table is
4848 collision resistant it also makes it possible to have several
4849 duplicate keys in the hash table. This function may be used to
4850 find all of the keys from the hash.
4852 Added user_context arguments to the SilcHashFunction,
4853 SilcHashCompare and SilcHashDestructor to deliver user specified
4856 Added new fuctions silc_hash_table_find[_all]_ext to do
4857 extended lookup with specified hash and compare functions and
4858 specified user contexts.
4860 Added new function silc_hash_table_add_ext to add the key
4861 with specified hash function and user context.
4863 Added new function silc_hash_table_foreach to traverse all
4864 entrys in the hash table. Added SilcHashForeach callback
4867 Added new function silc_hash_table_del_by_context to delete
4868 the entry only if the context associated with the key matches.
4870 Affected files are lib/silcutil/silchashtable.[ch].
4872 * Removed silc_hash_[server/client/channel]_id and added just
4873 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4874 silc_hash_id_compare to compare two ID's using as the hash table
4875 comparison function. Added also silc_hash_data to hash
4876 binary data and silc_hash_data_compare to compare it.
4878 * Removed silc_idlist_find_client_by_hash as it is not needed
4879 anymore. Affected file silcd/idlist.[ch].
4881 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4882 to use internally the SilcHashTable. The new ID Cache is a lot
4883 faster than the old one. Some of the ID Cache interface was also
4884 rewritten and obsolete and stupid functions were removed.
4886 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Added entry_count field to the SilcHashTable to keep the number
4889 of the entries in the table. Implemented the function
4890 silc_hash_table_rehash. Added new function
4891 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4893 Fixed a minor bug in silc_hash_table_free.
4895 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4896 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4897 into the lib/silcutil/silcutil.[ch].
4899 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4901 * Implemented a collision resistant hash table into the
4902 lib/silcutil/silchashtable[ch]. See the header and the source
4903 for the SilcHashTable API.
4905 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Merged dotconf version 1.0.2 into lib/dotconf.
4909 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Do not compile anything in lib/silcsim/* if the SIM support
4912 is not enabled. The tree should now compile without problems
4915 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Compiled the SILC under cygwin. Compiled and tested briefly
4918 without problems. More tests needed. The SIMs didn't compile
4921 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4923 * Fixed possible crash in silc_get_username in the
4924 lib/silcutil/silcutil.c.
4926 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Fixed a va_arg in silc/client_ops.c.
4930 * Oops, RC5 routines were named AES and caused some problems
4931 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4933 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added new SilcIDIP structure into the lib/silccore/id.h and
4936 replaced the old `ip' fields from all SILC ID's to that type.
4937 This is a step towards IPv6 support.
4939 The silc_id_get_len takes now the ID as an extra argument.
4940 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4941 both IPv4 and IPv6 based ID's.
4943 The affected files are lib/silccore/id.[ch] and other files
4944 around the tree using these routines.
4946 * Removed the ID length arguments in server from various
4947 silc_server_send_notify_* routines -> they are not needed
4950 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Fixed memory leak in silc_encode_pem_file in the file
4953 lib/silcutil/silcutil.c.
4955 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Check minor version as well in the SKE. Affected files are
4958 silcd/protocol.c and lib/silcclient/protocol.c.
4960 * Added --identifier option to the server so that an identifier
4961 can be when creating the public key for the server. Affected
4962 file is silcd/silcd.c.
4964 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4965 lib/silccrypt/silcpkcs.c.
4967 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Register default ciphers and stuff when using -C option with
4970 the server. Affected file sildc/silcd.c.
4972 * Put back the servers public key filename format, it is better
4973 than the new one. For now, the client keys are saved with the
4974 new filename format. The affected file silc/client_ops.c.
4976 * Implemented the Cipher API for the rest of the ciphers that
4977 did not implement it or implemented it the wrong way.
4979 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Register default ciphers and stuff when using the -S option
4982 in the client. Affected file silc/silc.c. Same also when
4983 creating new key pair with -C option.
4985 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Fixed the silc_verify_public_key client operation function to
4988 save the public keys differently. The fingerprint is now
4989 used as filename and not the hostname. This way also the
4990 client keys are saved uniquely and not with hostnames. The
4991 affected file is silc/client_ops.c.
4993 * Trimmed the silc_hash_fingerprint function to remove extra
4994 whitespaces from the end of the fingerprint. The affected
4995 file is lib/silccrypt/silchash.c.
4999 * Added silc_cipher_register_default function to register all
5000 default ciphers. It can be used when configuration files
5001 does not exist and the application does not want any specific
5002 ciphers in any specific order.
5004 The SilcDList is now used as silc_cipher_list dynamically
5005 allocated cipher list. Removed the static list all together
5006 and now all ciphers must be allocated to the dynamic list.
5007 The silc_cipher_alloc routine was changed to check only the
5010 All silc_cipher_* routines that used to return int returns
5013 The affected files lib/silccrypt/silccrypt.[ch].
5015 * The same thing was done to silc_hash_* as for silc_cipher_*
5016 routines. Affected files lib/silccrypt/silchash.[ch].
5018 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5019 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5020 Added also silc_pkcs_[un]register[_default] functions.
5021 Removed the data_context from the PKCS API.
5023 * Added silc_hmac_register_default function to register default
5024 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5025 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5026 to unregister all hmacs at once.
5028 * Register the default ciphers, hash functions, PKCSs and HMACs
5029 if client's configuration file does not exist. The affected
5032 * The client did not load the hash functions from the SIM
5033 modules at all. Added support for this. Affected file is
5034 silc/clientconfig.c.
5036 * When decoding public key with silc_pkcs_public_key_decode, check
5037 the supported algorithm only if PKCS are registered. Affected
5038 file lib/silccrypt/silcpkcs.c. The same was done with the
5039 silc_pkcs_private_key_decode.
5041 * Fixed the SILC List routines to keep the list always in order.
5042 It used to change the list's order when traversing the list but
5043 not it preserves the order. Affected file lib/trq/silclist.h.
5045 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Added the client library to use the SilcSocketConnection's
5048 reference counter (by silc_socket_dup) to prevent the bug that
5049 the socket object may be freed underneath async operation.
5051 * The name resolv library checking fixes in the configure.in.pre.
5054 * Created new version of the protocol drafts for future
5055 development. The -03 drafts are the ones that will be changed
5056 in the trunk now and the -02 will remain as they are.
5058 * Send list of CUMODE notifys to the router when announcing
5059 the channel users to the router. Affected file silcd/server.c.
5060 If the router receiving channel founder CUMODE for a channel
5061 that already has channel founder it will send CUMODE notify
5062 to the sender to remove the channel founder rights from the
5063 announced client. Affected file silcd/packet_receive.c.
5065 * The CUMODE notify may now use Server ID as well as the entity
5066 who changes the mode. Updated protocool specs.
5068 * Updated INSTALL and README files.
5070 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5072 * New web pages in the http://silc.pspt.fi. The pages was
5077 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5079 * Implemented the [DenyConnectin] config section in the server.
5080 Added silc_server_config_denied_conn to check whether incoming
5081 connection is denied. Affected file silcd/serverconfig.[ch].
5083 * Do not check the ports when checking the incoming configuration
5084 data if the port is 0, meaning any. Affected file is
5085 silcd/serverconfig.c.
5087 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Fixed buffer overflow in silc_string_compare in the file
5090 lib/silcutil/silcutil.c.
5092 * Fixed double free in silc_server_command_leave in the file
5095 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Fixed the version checking in the server. Affected file is
5100 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Fixed the configuration data fetching when accepting new
5103 connections in the server. Affected file silcd/server.c.
5105 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5107 * Added `sender_entry' argument to the function
5108 silc_server_packet_relay_to_channel so that we can check
5109 whether some destination actually belongs to the same route
5110 the sender belongs (ie, we must not resend the packet to the
5111 sender). Affected file silcd/packet_send.[ch].
5113 * Added `servername' field to the SilcClientEntry in the server
5114 to hold the name of the server where client is from. Affected
5115 file is silcd/idlist.h.
5117 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Moved the channel message encrypting in the router betwen
5120 router connections from silc_server_channel_message to the
5121 silc_server_packet_relay_to_channel since we want to check
5122 whether we have anybody channel before encrypting anything.
5123 Affected files silcd/packet_[receive/send].c.
5125 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Fixed the [AdminConnection] server config section to support
5128 multiple entries. Affected file silcd/serverconfig.c.
5130 * Added support into the server to check the validity of the
5131 incoming connection before executing any KE or authentication
5134 * The connection configuration is now saved to the KE and
5135 connection auth protocol contexts and not fetched anymore in
5136 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5138 * The local hosts listenning address and port is also resolved
5139 now when starting the server. We want to have the socket object
5140 to include the real address and port for the listener. Added
5141 new function silc_net_check_local_by_sock into the files
5142 lib/silcutil/silcnet.[ch].
5144 * Fixed a broadcast bug in server -> do not broadcast if we
5147 * Fixed a routing bug. Do not route broadcast packets ever.
5148 Broadcast packets must be processed always and not routed since
5149 they may be destined to some other host than yourself and thus
5150 would get routed without no good reason. Affected file is
5153 * Added function silc_server_config_is_primary_route to check
5154 whether primary router connection has been configured (a router
5155 configuration that we are initiating). If there is not, we
5156 will assume that there is only two routers in the SILC network
5157 and we will use the incoming router connection as our primary
5158 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5160 * Changed the order of the broadcasting. Broadcast _after_ the
5161 packet has been processed not before. Affected file is
5164 * Fixed a [ClientConnection] parsing bug. The port was never
5165 parsed correctly thus resulting to port 0. Affected file
5166 silcd/serverconfig.c.
5168 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5169 argument and did not set the broadcast packet flag. Affected
5170 file silcd/packet_send.c. Fixed same bug in the function
5171 silc_server_send_notify as well.
5173 * If we receive NEW_ID packet for our own ID in the server, ignore
5176 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Removed the nickname from the Private Message Payload.
5181 Updated the code and the protocol specs.
5183 * Updated protocol specs for submitting to the IETF.
5185 * Tweaked the Random Number Generator a bit. Affected file
5186 lib/silccrypt/silcrng.c. Exported a new function
5187 silc_rng_[global]_add_noise which can be used to add more
5190 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5192 * Do not parse packets with different timeout when protocol
5193 is active -> may cause problem with rekey. Affected file
5196 * When server receives signoff notify it must not create
5197 new channel key if the client is on any channels since the
5198 sender of the signoff notify will create it.
5200 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Added printing of error messages during SKE protocol from the
5203 failure packet sent by server during SKE. Affected file
5206 * Removed the client's failure_callback handling with timeout
5207 and handle it immediately when received.
5209 * The SKE library returned wrong type in SUCCESS and FAILURE
5210 packets. They must be 32 bit MSB not 16 bit MSB.
5212 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5214 * Ok, rewrote the logic of the re-key and now it seems to work.
5215 I tested it on high traffic with frequent re-keys without
5216 problems. Added hmac_receive (and renamed hmac to hmac_send)
5217 in SilcClientConnection in lib/silcclient/client.h and
5218 in SilcIDListData in silcd/idlist.h. Also, removed the
5219 SilcPacketParserContext's cipher and hmac fields as they are
5220 not needed anymore and actually caused some problems when
5221 the ciphers and hmac's changed underneath the packet parser.
5223 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * If re-key protocol is active then process the incoming packets
5226 synchronously since we must assure that icoming packets encrypted
5227 with the old key is processed before the new keys is set to
5228 use. This is true other packets than for REKEY packets.
5229 Affected file silcd/server.c. The same was done to client library
5230 as well, affected file lib/silcclient/client.c.
5232 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Fixed bug in client and server to accept the force send if
5235 the packet is send from silc_[server/client]_packet_process
5236 function. Otherwise the packets are never delivered, oops.
5238 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5240 * Disable force sending of packets when REKEY protocol is active.
5241 We must assure that no packet is sent directly when rekey is
5242 performed. All packets must be sent through packet queue.
5243 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5244 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5245 function is silc_[server/client]_packet_send_real to check
5248 * Replaced the SIM paths from example config files to
5249 /usr/local/modules. Also, make install creates now
5250 /usr/local/silc/logs directory to hold all the SILC server
5253 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Made the configure.in.pre work on Solaris. Patch by salo.

5264 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5266 * When MAC computation fails the silc_packet_decrypt returned 0
5267 even though it was supposed to return -1. Fixed this. The
5268 affected file is lib/silccore/silcpacket.c.
5270 * Do not replace the config files in /etc/silc (in make install)
5271 if they already exist. Affected file ./Makefile.am.
5273 * Do not send re-key packets immediately but through packet queue.
5274 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5276 * Changed silc_net_check_host_by_sock to return FALSE if the
5277 IP/DNS could not be resolved. Though, it returns the IP address
5278 now even if it could not resolve it (but returns also FALSE).
5279 Affected file lib/silcutil/silcnet.[ch].
5281 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5283 * Added silc_pkcs_decode_identifier to decode the public key's
5284 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5285 Added also silc_pkcs_free_identifier. Added also new context
5286 SilcPublicKeyIdentifier.
5288 * Added -S option to the silc client. It is used to dump the
5289 contents of the specified public key file.
5291 * Changed the PKCS api to return the public key length when
5292 setting the public key.
5294 * Fixed a fatal bug in the public and private key file loading.
5295 Affected file lib/silccrypt/silcpkcs.c.
5297 * Execute the packet parsing for client with zero (0) timeout
5298 if the protocol is active. Affected file silcd/server.c.
5300 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Made the key generation options to the silcd program. Added
5303 -C option, equivalent to client's option.
5305 * Added new [ServerKeys] config section to the server. It
5306 configures the server's public and private key.
5308 * Defined generic Public Key Payload into the protocol
5309 specification to send specific type of public keys and
5312 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5313 public key or certificate.
5315 * Implemented the GETKEY command to the server and to the
5316 client library and on user interface.
5318 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Made preliminary `make install' work.
5322 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Added SilcServerRekey context into silcd/idlist.h.
5326 * Added the PFS support as defined in the specification to the
5327 SKE protocol. Affected files lib/silcske/*.c.
5329 * Added `ske_group' field to the SilcServerRekey context to hold
5330 the number of the SKE group that is used with PFS in re-key.
5331 Affected file silcd/idlist.h.
5333 * Added PFS re-key support to the server. Affected file is
5336 * Added silc_protocol_cancel to cancel execution of the next
5337 state of the protocol. Affected file is
5338 lib/silccore/silcprotocol.[ch].
5340 * Added the re-key support with and without PFS to the client
5341 library. Re-key is performed once in an hour, by default.
5343 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5344 Added silc_client_rekey_callback and silc_client_rekey_final.
5345 Affected files are lib/silcclient/protocol.[ch] and
5346 lib/silcclient/client.[ch].
5348 * Removed the `hmac_key' and `hmac_key_len' fields from the
5349 SilcClientConnection structure; not needed. Affected file is
5350 lib/silcclient/client.h.
5354 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5356 * Do not ask whether user wants to use the negotiated private key
5357 for private messages, just use it. Affected file is
5358 silc/local_command.c.
5360 * Added `send_enc_key' and `enc_key_len' fields to the
5361 SilcIDListData structure since they are needed in the re-key
5362 phase. Affected file is silcd/idlist.[ch].
5364 * Implemented the simple re-key protocol into the server.
5365 Affected files silcd/server.c and silcd/protocol.[ch]. The
5366 re-key will be performed once in an hour, by default.
5368 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5369 Added silc_server_rekey, silc_server_rekey_callback and
5370 silc_server_rekey_final.
5372 * Removed Tunneled flag from the protocol. Updated the code
5373 and the specifications.
5375 * Adde `pfs' field to the SilcIDListData to indicate whether
5376 the PFS is to be performed in the re-key. Affected file is
5379 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5382 int64 of at least the xintXX size. If void * is less that 4
5383 bytes uint32 * will be used. Defined bool as boolean.
5385 * Changed _ALL_ unsigned long and unsigned int to uint32,
5386 unsgined short to uint16 in the source tree.
5388 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5389 not handle clients that has entry->data.registered == FALSE.
5390 They are not in the network anymore. Affected file is
5393 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5395 * Implemented the sending of the SERVER_SIGNOFF notify in the
5396 server. Affected file is silcd/server.c.
5398 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5399 Added also silc_notify_payload_encode_args into the
5400 lib/silccore/silcnotify.[ch].
5402 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5403 Affected file silcd/packet_receive.c.
5405 * Implemented the SERVER_SIGNOFF notify handling in the client
5406 library. Affected file lib/silcclient/client_notify.c. Also,
5407 implemnted the printing of the SERVER_SIGNOFF info to the
5408 application. Affected file silc/client_ops.c.
5410 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5411 if the deleting was successful. Affected file silcd/idlist.[ch].
5413 * Added support for public key authentication in the connection
5414 authentication protocol in the client library. Affected file
5415 lib/silcclient/protocol.c.
5417 * Changed the server's silc_idlist_get_clients_by_* interface
5418 to support already allocated array so that new entries may be
5419 added to pre-allocated array. Affected file silcd/idlist.[ch].
5420 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5421 and command replies.
5423 * All command reply functions in the server now calls the
5424 pending command callback even if error occured. This way the
5425 error will be delivered to the client as well. Affected files
5426 silcd/command.c and silcd/command_reply.c.
5428 * Fixed INFO command to return local server's info if no server
5429 was provided. Affected file lib/silcclient/command.c.
5431 * Removed RESTART command for good. Updated the code and the
5434 * Rewrote parts of the task system. It is a bit simpler now.
5435 Removed unsued task priorities. The affected files are
5436 lib/silcutil/silctask.[ch].
5438 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5440 * Moved the USERS printing from the library to the application.
5441 Affected files lib/silcclient/command.c and silc/client_ops.c.
5443 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5447 * Added channel key re-key support. The re-key is perfomed
5448 only by the router and is done once in an hour. Added `rekey'
5449 field to the SilcChannelEntry in the server. Affected files
5450 silcd/server.c and silcd/idlist.h.
5452 * Added silc_task_unregister_by_context into the file
5453 lib/silcutil/silctask.[ch].
5455 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Added SILC_UMODE_GONE mode to indicate when the client is not
5458 present in the SILC network. Added also support to the local
5459 command AWAY that will set this mode. Added support of showing
5460 "xxx is gone" in WHOIS command. The USERS command shows the
5461 gone status as well.
5463 * Fixed setting server and router operator privileges in the
5464 server's UMODE command. Affected file silcd/command.c.
5466 * Merged the SKE KE1 and KE2 payloads into one payload. The
5467 new KE payload is equivalent to the old KE2 payload.
5469 Cleaned up the SKE Start Payload parsing. It now uses the
5470 simple buffer unformatting to do the parsing. A lot faster
5473 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5474 to the SKE that is used to indicate whether both of the SKE
5475 parties should perform authentication. By default only the
5476 responder performs authentication. By setting this flag also
5477 the initiator must do authentication. By default it is unset
5478 since in normal SKE case, client to server connection, only
5479 the responder should do authentication. When doing SKE between
5480 two clients both should perform authentication. Updated the
5481 code and the protocol specs.
5483 * A little fix to IDENTIFY command in the server. Search the
5484 client first by hash not nickname. Affected file is
5487 * Fixed the silc_client_close_connection to support closing
5488 the client to client connections wihtout deleting too much
5489 data. Affected file lib/silcclient/client.c.
5491 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5492 are received if protocol used to be active but is not anymore
5493 the application would crash due to NULL pointer dereference.
5494 Affected files silcd/server.c and lib/silcclient/client.c.
5496 * Added `hash' field to the SilcClientConnection to include
5497 the hash function negotiated in the SKE protocol.
5499 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5500 to set the channel founder authentication data. A client can
5501 claim the founder rights later by providing the authentication
5502 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5503 This way the channel founder can regain the channel founder
5504 privileges even it is left the channel. This works only on
5505 local server and the client must be connected to the same
5506 server to be able to regain the founder rights. Updated the
5507 protocol specs accordingly.
5509 Added support to the CMODE command in the client to set the
5510 founder auth data. Read the README to see how to set it.
5512 Added support to the CUMODE command to claim the founder
5513 rights. Read the README to see how to do it.
5515 Added support for the founder authentication to the Channel
5516 Entry in the server. Affected file silcd/idlist.h.
5518 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5519 server's CMODE command. Affected file silcd/command.c.
5521 * Added the following new functions into lib/silccore/silcauth.[ch]:
5522 silc_auth_get_method and silc_auth_get_data.
5524 * The server now saves the remote hosts public key to the
5525 SilcIDListData pointer. Affected file silcd/protocol.c.
5527 * The normal server now does not remove the channel entry from
5528 the cache if the founder authentication data is set. It used
5529 to remove it if the founder was the last one on the channel on
5530 the server and left the channel. The auth data is saved and
5531 if the channel is re-joined later the old entry is used with
5532 the old auth data. Affected files silcd/command_reply.c and
5535 * Removed the `pkcs' field from the SilcIDListData structure
5536 in the server; it is not used. Affected file silcd/idlist.h.
5538 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Fixed packet processing on slow links. Partial packets were
5541 never re-processed because the incoming data buffer was cleared
5542 by the application. Application must not directly clear the
5543 sock->inbuf, the packet processing routines handle it. Fixed
5544 this in client library and in server.
5546 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Fixed the WHOIS and IDENTIFY send reply function to really
5549 check whether to send list or just one entry. Affected file
5552 * Cleaned up the LEAVE command's channel key distribution. The
5553 affected file silcd/command.c.
5555 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5556 can enforce the channel mode as well. In that case the ID
5557 includes the ID of the server. The code now enforces the
5558 mode change if the router have different mode than the server.
5560 * The notify client operation with CMODE_CHANGE notify can now
5561 return NULL client_entry pointer if the CMODE was not changed
5562 by client. Application must check for this.
5564 * Added <Server ID> argument to INFO command to support server
5565 info fetching by Server ID.
5567 * Added silc_server_announce_get_channel_users to get assembled
5568 packets of channel users of the specified channel. Affected
5569 file silcd/server.[ch].
5571 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5572 was freed underneath the ID Cache.
5574 * Re-announce clients when the server received CHANNEL_CHANGE
5575 notify from the router. Affected file silcd/packet_send.c.
5577 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5580 crashed since it did not handle the fact that there is no cipher
5581 called "3" and didn't check the error condition. Now fixed.
5583 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5584 flag. It can be used to send message requests.
5586 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Implemented the RESTART command in the client.
5590 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5591 notice type messages. Added notice printing to the user
5594 * The channel keys are not re-generated if the channel's mode
5595 is PRIVKEY, ie private key on the channel exists. Affected
5596 files silcd/server.c and silcd/command.c.
5598 * Fixed a little bug in channel message delivery when channel
5599 private keys are set in the server. Affected file is
5600 silcd/packet_send.c.
5602 * Changed the setting on channel->on_channel = TRUE from the
5603 silc_client_save_channel_key to the JOIN command reply. The
5604 key payload is not received if the private channel key is set.
5605 Affected file lib/silcclient/command_reply.c and the
5606 lib/silcclient/client_channel.c.
5608 * When the CMODE_CHANGE notify is sent and the channel private
5609 key mode is removed the channel key must be re-generated in
5610 other cells as well. Added this support for the router in the
5611 silcd/packet_receive.c.
5613 * Added new local command NOTICE to send notice message on
5614 channel. Affected file silc/local_command.[ch].
5616 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Added new local command ME to the client. It is used to send
5619 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5620 some action. Affected file silc/local_command.[ch].
5622 * Changed channel_message and private_message client operations
5623 to deliver the message flags to the application. Added also
5624 the `flags' arguments to the silc_client_send_channel_message
5625 and silc_client_send_private_message functions. Affected file
5628 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Redefined the Private Message Payload to support private message
5631 keys and to support the new private message flags. Updated
5632 the protocol specs. Flags makes it possible to have for example
5633 CTCP style messages.
5635 * Added new type SilcPrivateMessagePayload and defined an API
5636 for it in the lib/silcclient/silcprivate.[ch].
5638 * Tested private message private keys successfully. Tested the
5639 private message key set, unset and list commands with the new
5642 * Redefined the Channel Message Payload to include the channel
5643 message flags (equal with private message flags) to support
5644 for example CTCP style messages.
5646 * Defined some of the message (for channel and private message)
5647 flags. Updated the protocol specs and added the flags to the
5648 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5650 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added SilcKeyAgreementStatus type to the key agreement routines
5653 to indicate the current status and error if one occured.
5654 The status types are defined in the lib/silcclient/silcapi.h.
5656 * Added new local command KEY that is used to set and unset private
5657 keys for channels, set and unset private keys for private messages
5658 with remote clients and to send key agreement requests and
5659 negotiate the key agreement protocol with remote client. The
5660 key agreement is supported only to negotiate private message keys,
5661 it currently cannot be used to negotiate private keys for channels,
5662 as it is not convenient for that purpose.
5664 * Fixed a minor pending callback setting bug in the function
5665 silc_client_get_client_by_id_resolve, now the function works.
5666 Affected file lib/silcclient/idlist.c.
5668 * Added function silc_net_get_local_port to get local bound
5669 port by socket. Added to lib/silcutil/silcnet.[ch].
5671 * Added `sockets' and `sockets_count' fields to the SilcClient
5672 object. They hold the sockets of the listenning sockets in
5673 the client. Listenning sockets may be for example the key
5674 agreement server. Affected file lib/silcclient/client.[ch].
5675 Added functions the silc_client_add_socket and the
5676 silc_client_del_socket. They are exported to the application
5679 * Added ~./silc/clientkeys to support other client's public keys.
5681 * Renamed verify_server_key client operation to verify_public_key
5682 and added one argument to indicate the type of the connection
5683 (server, client etc.).
5685 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added silc_server_connection_auth_request to handle the
5688 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5689 silcd/packet_receive.[ch].
5691 * Added silc_server_send_connection_auth_request into the
5692 silcd/packet_send.c to send the connection auth request packet.
5694 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5697 * Fixed the public key authentication in responder side in the
5698 server. The `auth_data' pointer includes the SilcPublicKey
5699 not the path to the public key. Affected file silcd/protocol.c.
5701 * Implemented the public key authentication in the initiator side
5702 in the server. Affected file silcd/protocol.c.
5704 * Removed the [RedirectClient] config section from the server
5705 configuration. Is not needed and I don't want to implement it.
5707 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Cleaned up the CMODE command in the server. It now works
5710 correctly and supports all the modes defined in the protocol.
5711 Affected file is silcd/command.c.
5713 * Added `hmac_name' field to the SilcChannelEntry in the server
5714 to hold the default HMAC of the channel. It can be set when
5715 creating the channel (with JOIN command). Affected files
5718 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5719 type to indicate the change of the current cipher and hmac
5720 on the channel. Client can safely ignore the <cipher> argument
5721 (if it chooses to do so) since the CHANNEL_KEY packet will
5722 force the channel key change anyway. The <hmac> argument is
5723 important since the client is responsible of setting the new
5724 HMAC and the hmac key into use.
5726 * Fixed the CMODE command in the client library as well.
5728 * Tested CMODE command in router environment successfully.
5730 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Show the version of the remote client (or server) when connecting
5733 to the server. It is logged to the log file. Affected file
5734 is silcd/protocol.c.
5736 * Fixed the KILLED notify handling in the client library. The
5737 client must be removed from all channels when receiving the
5740 Also, do not remove the client entry when giving the KILL
5741 command but when the KILLED notify is received.
5743 * Removed silc_idlist_find_client_by_nickname from the server.
5744 Not needed anymore. Affected files silcd/idlist.[ch].
5746 * Implemented the CHANNEL_CHANGE notify type handling to the
5747 server. Affected file silcd/server.c.
5751 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5753 * Added silc_server_send_notify_invite to send the INVITE
5754 notify between routers.
5756 * Implemented the INVITE command correctly to the server.
5758 * Implemented the INVITE notify type handling in the server.
5760 * Implemented the INVITE command to the client library and on the
5763 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Added function silc_server_get_client_resolve to find the
5766 client entry by ID from all ID lists and then resolve it
5767 (using WHOIS) if it cannot be found. Affected file is
5770 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Implemented the BAN command to the client library.
5774 * The JOIN command in the server now checks the invite list
5777 * Changed the silc_command_reply_payload_encode_va and the
5778 silc_command_payload_encode_va to support that if argument is
5779 NULL it ignores and checks the next argument. Affected file
5780 lib/silccore/silccommand.c.
5782 * Added silc_server_send_notify_ban to send the BAN notify
5783 type between routers.
5785 * Chaned the silc_notify_payload_encode to support that if
5786 argument is NULL it ignores and checks the next argument.
5787 Affected file lib/silccore/silcnotify.c.
5789 * Tested ban lists in router environment successfully.
5791 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5793 * Implemented BAN command to the server, in silcd/command.[ch].
5795 * Removed the BAN and INVITE_LIST modes from the CMODE command
5798 * Added function silc_string_match to regex match two strings.
5799 Affected files lib/silcutil/silcutil.[ch].
5801 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5803 * Redefined parts of the SilcChannelEntry in the server to support
5804 the new ban and invite lists.
5806 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Redefined the INVITE command. The same command can be used to
5809 invite individuals to the channel but also to manage the invite
5810 list of the channel (to add to and remove from the invite list).
5811 Updated the protocol specs.
5813 * Added new command SILC_COMMAND_BAN that can be used to manage
5814 the ban list of the channel. Updated the protocol specs.
5816 * Removed the channel modes: the SILC_CMODE_BAN and the
5817 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5818 in the CMODE command. The equivalent features are now available
5819 using INVITE and BAN commands. Updated the protocol specs.
5821 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5822 in the network about change in the current ban list. The notify
5823 type is not used by the client.
5825 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5826 support the invite lists.
5828 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5830 * Added new function silc_string_regexify that converts string
5831 including wildcard characters into regex string that can
5832 be used by the GNU regex library. Added into the file
5833 lib/silcutil/silcutil.[ch].
5835 Added silc_string_regex_combine to combine to regex strings
5836 into one so that they can be used as one regex string by
5837 the GNU regex library. Added into the file
5838 lib/silcutil/silcutil.[ch].
5840 Added silc_string_regex_match to match two strings. It returns
5841 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5843 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Imported GNU regex to the soruce tree into lib/contrib.
5846 Fixed some compiler warning from the regex.c.
5848 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Fixed MOTD command in the server to work in router environment.
5852 * Fixed the MOTD command in the client library to support
5853 the server argument in the command.
5855 * Added `nickname_len' argument to the silc_idlist_add_client
5856 in the server, as the `nickname' argument may be binary data
5859 * Added silc_idlist_get_channels to return all channels from
5862 * Implemented LIST command to the server. Affected file is
5865 * Implemented the LIST command to the client library and on the
5868 * Added [<user count>] argument to the LIST command reply.
5869 With private channels the user count is not shown.
5871 * Updated TODO and README.
5873 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * The client entry's data.registered must be TRUE even with
5876 global client entry on global client list. The data.registered
5877 is used to check whether the client is anymore in the network,
5878 for example with WHOWAS command so it must be valid.
5880 * Fixed the WHOWAS command in the server. It now actually works
5881 in router environment. Added function into silcd/command_reply.c
5882 silc_server_command_reply_whowas_save.
5884 * Added silc_idlist_purge function to the silcd/idlist.c
5885 to periodically purge the ID Cache.
5887 * Fixed INFO command in the server. It works now in router
5888 environment. Added <server name> argument to the INFO command
5889 reply. Updated the protocol specs.
5891 * Fixed minor bug in silc_idcache_purge to not purge if the
5892 expire value is zero.
5894 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5895 they were buggy because of the WHOWAS information.
5897 * Fixed local command MSG to handle the async resolving of
5898 the remote client properly. It used to fail the first MSG.
5899 Affected file silc/local_command.c.
5901 * Added `data_len' field to SilcIDCache context.
5903 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Update TODO. Todo in commands in the server.
5907 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5910 used by routers as broadcast packet to inform other routers
5911 about the changed user mode.
5913 Implemented the notify handling in the server. Affected file is
5914 silcd/packet_receive.c. Added the function
5915 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5917 * Added new generic Channel Payload and deprecated the New Channel
5918 Payload. The New Channel Payload is now the generic Channel
5921 * Added new argument `mode' to the silc_server_send_new_channel
5922 as it is required in the Channel Payload now.
5924 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5925 and created a new and real SilChannelPayload to represent the
5926 new generic Channel Payload. Implemented the encode/decode
5927 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5929 * Added silc_server_get_client_channel_list to return the list
5930 of channels the client has joined for WHOIS command reply.
5931 Affected file silcd/server.[ch].
5933 * Implemented the channel list sending in the WHOIS command reply
5934 in server and in the client.
5936 Implemented the channel list displaying on the user interface
5937 as well. Affected file silc/client_ops.c.
5939 * Added silc_channel_payload_parse_list to parse list of Channel
5940 Payloads. It returns SilcDList list of SilcChannelPayloads.
5941 Client for example can use this function to parse the list of
5942 channels it receives in the WHOIS command reply. The caller
5943 must free the list by calling silc_channel_payload_list_free.
5944 Affected files lib/silccore/silcchannel.[ch].
5946 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5948 * Added one new argument <user mode> to the WHOIS command reply
5949 to return the mode of the user in SILC. Updated the protocol
5952 Implemented it to the server and client.
5954 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Fixed the mode printing on the user interface on joining.
5957 Affected file silc/client_ops.c.
5959 * Implemented the UMODE command and user modes in general to the
5960 client library and to the user interface.
5962 * Implemented the UMODE command to the server.
5964 * The server now sends UNKNOWN_COMMAND error status if client sends
5965 unknown command. Affected file silcd/command.c.
5967 * All server commands now handle the command identifier the right
5968 way when sending the command reply to the client. The client can
5969 use to identify the command replies with the identifier.
5971 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added silc_server_get_client_route to resolve the route to
5974 the client indicated by the client ID. Affected file is
5977 * Added silc_server_relay_packet as general function to relay
5978 packet to arbitrary destination. This deprecates functions
5979 like _send_private_message_key, _relay_notify etc. Affected
5980 file is silcd/packet_send.[ch].
5982 Removed silc_server_send_key_agreement,
5983 silc_server_send_private_message_key and
5984 silc_server_packet_relay_notify functions from the file
5985 silcd/packet_send.[ch].
5989 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5990 server. Affected file silcd/packet_receive.[ch].
5992 * Implemented the KILL command to the client. Implemented the
5993 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5994 Affected files lib/silcclient/command[_reply].c and
5995 lib/silcclient/client_notify.c. Implemented the KILL notify
5996 printing in the user inteface.
5998 * Fixed a lot silc_parse_nick memory leaks from the client
5999 library in the file lib/silcclient/command.c.
6001 * Changed the silc_server_send_notify_on_channels's `sender'
6002 argument from SilcSocketConnection to SilcClientEntry to
6003 check the sender as entry and not as connection object and not
6004 to send to the client provided as argument. The affected file
6005 is silcd/packet_send.[ch].
6007 * The notify packets that are destined directly to the client used
6008 to not to be processed by the server. Now changed that and the
6009 server processes all notify packets. After relaying the packet
6010 to the client the notify packet is processed in the server.
6012 * The silc_server_free_client_data now checks whether there is
6013 pending outgoing traffic for the client and purges the data to
6014 the network before removing the client entry.
6016 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6019 an client is killed from the SILC Network. Updated the protocol
6022 Added new function silc_server_send_notify_killed to the
6023 silcd/packet_send.[ch].
6025 * Added function silc_server_packet_relay_notify to relay notify
6026 packets that are destined directly to a client. In this case
6027 the server does not process the notify packets but merely relays
6028 it to the client. Affected file silcd/packet_send.[ch].
6030 Added also silc_server_packet_process_relay_notify to check
6031 whereto relay the notify. Affected file is
6032 silcd/packet_receive.[ch].
6034 * Implemented the KILL command to the server.
6038 * Added the backup schema desgined last fall to the protocol
6039 specs for everyone to see. The specification is in the
6040 *-spec-xx.txt draft and the packet type definitions for the
6041 backup routers is in *-pp-xx.txt draft. Thusly, added also
6042 new packet type SILC_PACKET_CELL_ROUTERS.
6044 * A big security problem in the implementation discovered. The
6045 signoff of an client did not cause new channel key generation
6046 which it of course should've done. The channel keys must be
6047 always re-generated when client leaves (or signoffs) the channel.
6048 The silc_server_remove_from_channels funtion now handles
6049 the channel key re-generation.
6051 * Added `sender' argument to the silc_server_send_notify_on_channels
6052 to not to send the client provided as argument. Affected file
6053 silcd/packet_send.[ch].
6055 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6057 * Implemented OPER and SILCOPER commands into the server and
6060 * Added silc_auth_verify and silc_auth_verify_data to verify
6061 the authentication directly from the authentication payload.
6062 It supports verifying both passphrase and public key based
6063 authentication. Affected file lib/silccore/silcauth.[ch].
6065 * Added `hash' field to the SilcIDListData structure. It is the
6066 hash negotiated in the SKE protocol. Affected file is
6069 * Slight redesigning of the SilcAuthPayload handling routines.
6070 Do not send SilcPKCS but SilcPublicKey as argument.
6072 * Implemented the public key authentication support to the
6073 serverconfig. The public key is loaded from the provided path
6074 and saved as authentication data to void * pointer. Thus,
6075 changed the unsigned char *auth_data to void *auth_data;
6077 * Fixed SHUTDOWN command to send the reply before the server
6078 is shutdown. :) Affected file silcd/command.c.
6080 * Fixed fatal bug in CONNECT command. The hostname was invalid
6081 memory and server crashed. Affected file silcd/command.c.
6083 * Fixed fatal bug in CLOSE command. The server_entry became
6084 invalid but was referenced later in the command. Affected file
6087 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Fixed fatal bug in failure packet handling. Server ignored
6090 the failure and thus crashed when it came.
6094 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6097 that the command may be executed only once in (about) 2 seconds.
6098 The old SILC_CF_LAG flag is same but allows command bursts up
6099 to five before limiting.
6101 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6102 server code. Various commands now includes the CF_LAG_STRICT
6103 flag to disallow any kind of miss-use of the command.
6105 * Fixed the silc_buffer_unformat to not to allocate any data
6106 if the length of the data is zero. It used to allocate the
6107 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6109 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Changed the format of AdminConnection configuration section
6112 in the server. Added username of the admin to the format.
6113 Affected files silcd/serverconfig.[ch].
6115 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6116 to return admin configuration data by host, username and/or
6119 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Implemented WHOWAS command to the server. Added the functions:
6123 silc_server_command_whowas_parse,
6124 silc_server_command_whowas_send_reply,
6125 silc_server_command_whowas_from_client and
6126 silc_server_command_whowas_from_server
6128 * Added <Client ID> argument to the WHOWAS command reply. Updated
6129 the protocol specs accordingly.
6131 * Implemented WHOWAS command and command_reply to the client
6134 Implemented the WHOWAS printing on the user interface.
6136 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6138 * Added new argument to the WHOWAS command reply, the real name.
6139 It is an optional argument. Updated the protocol specs.
6141 * Added SilcIDCacheDestructor callback that is registered when
6142 the SilcIDCache is allocated. The callback is called when
6143 an cache entry in the ID Cache expires, or is purged from the
6144 cache. Added into lib/silccore/idcache.[ch].
6146 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6147 to destruct the client entries when the cache entry expires.
6148 Other ID Cache's in server and in the client library ignores
6151 * If the ID Cache entry's `expire' field is zero then the entry
6152 never expires. Added boolean `expire' argument to the
6153 silc_idcache_add function in the lib/silccore/idcache.[ch].
6154 If it is TRUE the default expiry value is used.
6156 * Added silc_server_free_client_data_timeout that is registered
6157 when client disconnects. By default for 5 minutes we preserve
6158 the client entry for history - for WHOWAS command.
6160 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Added support to the server to enforce that commands are not
6163 executed more than once in 2 seconds. If server receives
6164 commands from client more frequently, timeout is registered
6165 to process the commands. Affected file silcd/command.c.
6166 Added new function silc_server_command_process_timeout.
6168 * Changed NICK_NOTIFY handling in client library to check that
6169 if the client's nickname was changed, so there is no need to
6170 resolve anything from the server.
6172 * Removed error printing from the WHOIS and IDENTIFY commands.
6173 If error occurs then it is ignored silently in the client library.
6174 The application, however, may map the received error to
6175 human readable error string. The application currently maps
6176 the NO_SUCH_NICKNAME error to string.
6178 * Made the command status message public to the application. Moved
6179 them from lib/silcclient/command_reply.c to
6180 lib/silcclient/command_reply.h. The application can map the
6181 received command status to the string with the
6182 silc_client_command_status_message function.
6184 * Added check to the server to check that client's ID is same
6185 as the Source ID in the packet the client sent. They must
6188 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Added dist-bzip hook to the Makefile.am to make bzip2
6191 compressed distributions.
6193 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Server now enforces the maximum length for the nickname and
6196 the channel as protocol specification dictates. 128 bytes for
6197 nickname and 256 bytes for channel name.
6199 * Moved the WHOIS printing to the application. The client libary
6200 does not print out the WHOIS information anymore, the application
6201 must do it. Renamed silc_client_command_reply_whois_print to
6202 the silc_client_command_reply_whois_save.
6204 The client's idle time is also sent to the application now, and
6205 the idle is shown on screen.
6207 * Added silc_client_command_reply_identify_save to save the
6208 received IDENTIFY entries.
6210 * Do not check for channel private keys in message sending and
6211 reception if the channel does not have the PRIVKEY mode set.
6212 Affected file lib/silclient/client_channel.c.
6214 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6217 just surfaced after chaning the JOIN procedure.
6219 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Added silc_client_get_clients_by_list to get client entries
6222 from Client ID list, that is returned for example by JOIN
6223 and USERS command replies. The application should use this
6224 function for example when JOIN command reply is received to
6225 resolve the clients already on the channel (library does not
6226 do that anymore as USERS command reply is not used in the JOIN
6227 procedure anymore). Affected files lib/silcclient/silcapi.h and
6228 lib/silcclient/idlist.c.
6230 * JOIN command reply and USERS command reply returns now SilcBuffer
6231 pointers instead of unsigned char pointers when returning
6232 the client list and mode list.
6234 * Added <Client ID> argument to the JOIN command reply, mainly
6235 for the server to identify for which client the command was
6236 originally sent. Updated protocol specs accordingly.
6238 * Added SilcDlist private_key pointer to the SilcChannelEntry
6239 in the client to support the channel private keys. Affected
6240 file is lib/silcclient/idlist.h.
6242 * Added SilcChannelPrivateKey argument to the function
6243 silc_client_send_channel_message so that application can choose
6244 to use specific private ke if it wants to. If it is not provided,
6245 the normal channel key is used, unless private keys are set.
6246 In this case the first (key that was added first) is used
6247 as the encryption key.
6249 * Implemented the support for channel private key handling.
6250 Implemented the following functions:
6252 silc_client_add_channel_private_key,
6253 silc_client_del_channel_private_keys,
6254 silc_client_del_channel_private_key,
6255 silc_client_list_channel_private_keys and
6256 silc_client_free_channel_private_keys
6258 Affected file lib/silcclient/client_channel.c.
6260 * Added the support for the private keys in the channel message
6261 sending and encryption and in the message reception and
6262 decryption. Affected funtions are
6263 silc_client_send_channel_message and silc_client_channel_message.
6265 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Added SKE's key verify callback to the client library's
6268 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6270 * Removed the statement that server (or router) must send USERS
6271 command reply when joining to the channel so that the client
6272 knows who are on the channel. Instead, the client list and
6273 client's mode list is now sent in the JOIN command reply to the
6274 client who joined channel. This is better solution.
6276 * Added function silc_server_get_users_on_channel and function
6277 silc_server_save_users_on_channel to the silcd/server.[ch].
6279 * Removed function silc_server_command_send_users from the
6282 * Do not show topic on the client library anymore. The topic is
6283 sent in the command reply notify to the application and the
6284 application must show the topic now.
6286 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Added client searching by nickname hash into the IDENTIFY and
6289 WHOIS commands in the server as they were clearly missing from
6290 them. Affected file is silcd/command.c.
6292 * Fixed a bug in private message receiving in the client library.
6293 The remote ID was freed and it wasn't supposed, now it is
6296 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Minor fix to the channel payload; allocate the data area, as it
6299 needs to be of specific length.
6301 * If the key agreement port is zero then the operating
6302 system will define the bound port. Affected files are
6303 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6305 * Added new function silc_channel_payload_decrypt into the file
6306 lib/silccore/silcchannel.[ch].
6308 * Moved the channel message etc, check from silc_packet_decrypt
6309 to applications. The library calls now a generic
6310 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6311 when the packet is either normal or special. This was done to
6312 allow more wide range of checking that was not allowed when
6313 the code was in library. Now applications can do virtually any
6314 checks to the packet and return to the library the decision how
6315 the packet should be processed. Affected files are
6316 lib/silccore/silcpacket.[ch].
6318 Added silc_server_packet_decrypt_check to the server and
6319 silc_client_packet_decrypt_check to the client library.
6321 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6322 to send with specified source and destination information.
6324 * Channel message delivery between routers was broken after the
6325 channel key distribution was fixed earlier. The channel key
6326 was used be to distributed to other routers as well which is not
6327 allowed by the protocol. Now this is fixed and channel keys
6328 really are cell specific and the channel message delivery between
6329 routers comply with the protocol specification.
6331 * Fixed various commands in server to check also the global list
6332 for the channel entry and not just the local list. The affected
6333 file silcd/command.c.
6335 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Added assert()s to buffer formatting and unformatting routines
6338 to assert (if --enable-debug) when error occurs. Affected
6339 file: lib/silcutil/silcbuffmt.c.
6341 * Changed to auto-reconnect to check whether the remote host is
6342 router and register the re-connect timeout if it is. It used
6343 to check that whether we are normal server, but router must do
6344 auto-reconnect with another router as well. Affected file
6347 * Removed the [<key len>] option from CMODE command as the cipher
6348 name decides the key length, nowadays. See the defined ciphers
6349 from the protocol specification.
6351 * Added [<hmac>] option to the CMODE command to define the HMAC
6352 for the channel. Added SILC_CMODE_HMAC channel mode.
6354 * Added [<hmac>] option for the JOIN command so that user can
6355 select which HMAC is used to compute the MACs of the channel
6358 * Added Hmac field to the Channel Message Payload. The integrity
6359 of plaintext channel messages are now protected by computing
6360 MAC of the message and attaching the MAC to the payload. The
6361 MAC is encrypted. Now, it is clear that this causes some
6362 overhead to the size of the packet but rationale for this is that
6363 now the receiver can verify whether the channel message decrypted
6364 correctly and also when private keys are set for the channel the
6365 receiver can decrypt the packet with several keys and check from
6366 the MAC which key decrypted the message correctly.
6368 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6369 lib/silccrypt/silccipher.[ch].
6371 * Added silc_hash_len to return the digest length into the
6372 lib/silcrypt/silchash.[ch].
6374 * Rewrote parts of Silc Channel Payload interface in the
6375 lib/silccore/silcchannel.[ch]. The encode function now also
6376 encrypts the packet and parse function decrypts it.
6378 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6380 * Fixed a minor formatting bug in the SKE's key material processing.
6381 It actually might have processed the keys wrong way resulting
6384 * Redefined the mandatory HMAC algorithms and added new algorithms.
6385 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6386 and hmac-md5 truncated to 96 bits. The mandatory is now
6387 hmac-sha1-96. Rest are optional (including the one that used
6388 to be mandatory). Rationale for this is that the truncated HMAC
6389 length is sufficient from security point of view and can actually
6390 make the attack against the HMAC harder. Also, the truncated
6391 HMAC causes less overhead to the packets. See the RFC2104 for
6394 * Added new [hmac] configuration section. The SKE used to use
6395 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6396 is of course wrong. The official names that must be proposed in
6397 the SKE are the ones defined in the protocol specification
6398 (hmac-sha1-96 for example). The user can configure any hmac
6399 using any hash function configured in the [hash] section. At
6400 least, the mandatory must be configured.
6402 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6404 * Added HMAC list to the SKE proposal list. It has now both
6405 hash algorithm list and HMAC list. This makes the protocol
6406 incompatible with previous versions. The SKE now seems to work
6407 the way it is supposed to work, for the first time actually.
6409 * Defined plain Hash algorithms to the protocol specification.
6412 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Implemented support for key agreement packets into the server.
6415 Added functions silc_server_key_agreement and
6416 silc_server_send_key_agreement. Other than these functions,
6417 server has nothing to do with this packet.
6419 * Added support for private message key packets into the server.
6420 Added functions silc_server_private_message_key and
6421 silc_server_send_private_message_key.
6425 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6426 called in the protocol's final callback instead in the END
6427 protocol state. This makes a little more sense and in the same
6428 time in client we can use the same protocol routines for normal
6429 key exchange and to key agreement packet handling as well.
6431 * Added to both client's and server's KE protocol context the
6432 SilcSKEKeyMaterial pointer to save the key material. We will
6433 bring the key material to the protocol's final callback by doing
6434 this. The final callback must free the key material.
6436 * Added SKE's packet_send callback into client's KE protocol
6437 context so that the caller can choose what packet sending function
6438 is used. This way we can use different packet sending when
6439 doing normal SKE when doing key agreement packet handling (in
6440 the key agreement packet handling we do not want to encrypt
6443 * Implemented the responder side of the key agreement routines
6444 in the client. The client can now bind to specified port and
6445 accept incoming key negotiation. The key material is passed
6446 to the application after the protocol is over.
6448 * Implemented the processing of incoming Key Agreement packet
6449 in the client. Added function silc_client_key_agreement to
6452 * Implemented the intiator side of the key agreement routines
6453 in the client. The client can now initiate key agreement with
6454 another remote client. The key material is passed to the
6455 application after the protocol is over.
6457 * Created client_keyagr.c to include all the key agreement
6460 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6461 SILC_TASK_CALLBACK except that it is not static.
6463 * Created client_notify.c and moved the Notify packet handling
6464 from the client.[ch] into that file.
6466 * Created client_prvmsg.c and moved all private message and
6467 private message key routines from the client.[ch] into that file.
6469 * Create client_channel.c and moved all channel message and
6470 channel private key routines from the client.[ch] into that file.
6472 * Changed silc_client_get_client_by_id_resolve to resolve with
6473 WHOIS command instead of IDENTIFY command, in the file
6474 lib/silclient/idlist.c.
6476 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Implemented the SKE's responder side to the Client library.
6480 * When FAILURE is received to the protocol do not trust it
6481 blindly. Register a timeout to wait whether the remote closes
6482 the connection as it should do it, only after that process the
6483 actual failure. This was changed to both client and server.
6485 * Added client_internal.h to include some of the structures
6486 there instead of client.h in lib/silcclient/.
6488 * Added function silc_task_unregister_by_callback to unregister
6489 timeouts by the callback function.
6491 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6493 * Some "Incomplete WHOIS info" errors has been appearing on the
6494 log files. Took away the entry->userinfo check from WHOIS
6495 reply sending. The entry->userinfo is now " " if client did not
6496 provide one. I thought this was fixed earlier but something
6497 is wrong still. Let's see if the error still appears.
6499 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Fixed a minor bug in the login when the channel key is
6502 re-generated in the server. It used to generate the key in
6503 wrong order and thus caused problems in the channel traffic.
6505 * Fixed a minor bug in channel key distsribution after
6506 KICK command. The key was not sent to the router even though
6509 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Added silc_ske_process_key_material_data as generic routine
6512 to process any key material as the SILC protocol dictates. The
6513 function is used by the actual SKE library but can be used by
6514 applications as well. This relates to the private message keys
6515 and the channel private keys since they must be processed the
6516 same way the normal SILC session keys. The protocol dictates
6517 this. Affected files: lib/silcske/silcske.[ch].
6519 Added also silc_ske_free_key_material to free the
6520 SilcSKEKeyMaterial structure.
6522 * Defined silc_cipher_set_key function to set the key for
6523 cipher without using the object's method function. The affected
6524 files: lib/silccrypt/silccipher.[ch].
6526 * Implemented silc silc_client_add_private_message_key,
6527 silc_client_add_private_message_key_ske,
6528 silc_client_del_private_message_key,
6529 silc_client_list_private_message_keys and
6530 silc_client_free_private_message_keys functions in the
6533 Added functions silc_client_send_private_message_key to send
6534 the Private Message Key payload and silc_client_private_message_key
6535 to handle incoming Private Message Key payload.
6537 * Added Cipher field to the Private Message Key payload to set
6538 the cipher to be used. If ignored, the default cipher defined
6539 in the SILC protocol (aes-256-cbc) is used.
6541 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Removed lib/silcclient/ops.h file.
6545 Redefined parts of the SILC Client Library API. Created new
6546 file silcapi.h that deprecates the ops.h file and defines the
6547 published Client Library API. Defined also private message key
6548 API and channel private key API into the file.
6550 This is the file that the application must include from the
6551 SILC Client Library. Other files need not be included by
6552 the application anymore.
6554 * Added new key_agreement client operation callback and also
6555 defined the Key Agreement library API for the application.
6557 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6559 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6560 is used by clients to request key negotiation between another
6561 client in the SILC network. If the negotiation is started it
6562 is performed using the SKE protocol. The result of the
6563 negotiation, the secret key material, can be used for example
6564 as private message key.
6566 Implemented the Key Agreement payload into the files
6567 lib/silccore/silauth.[ch].
6569 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Redefined ciphers for the SILC protocol. Added some new ciphers
6572 and defined the key lengths for the algorithms. Changed the
6573 code accordingly. The default key length is now 256 bits.
6575 * Fixed SKE key distribution function silc_ske_process_key_material
6576 when the key length is more than 128 bits. The default key
6577 length in SILC is now 256 bits.
6579 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6580 to indicate unsupported algorithm.
6582 * Renamed rijndael.c to aes.c and all functions as well.
6584 * Fixed a long standing channel key setting bug in client library.
6585 Weird that it has never surfaced before.
6587 * Fixed bug in channel deletion. If the entire channel is removed
6588 then it must also delete the references of the channel entry
6589 from the client's channel list as the client's channel entry and
6590 the channel's client entry share same memory.
6592 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Implemented CONNECT and SHUTDOWN commands in the client.
6596 * Implemented CLOSE command to the client.
6598 * Added the function silc_idlist_find_server_by_name into the
6599 files silcd/idlist.[ch].
6601 Added the function silc_idlist_find_server_by_conn into the
6602 files silcd/idlist.[ch].
6604 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * DIE command was renamed to SHUTDOWN. Updated the both code
6609 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6610 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6612 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6615 * Added function silc_server_create_connection function to create
6616 connection to remote router. My server implementation actually
6617 does not allow router to connect to normal server (it expects
6618 that normal server always initiates the connection to the router)
6619 so the CONNECT command is only good for connecting to another
6622 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6625 or some other client was kicked from the channel.
6627 Implemented the handling of the notify type to both client
6630 Implemented silc_server_send_notify_kicked to send the KICKED
6631 notify. It is used to send it to the server's primary router.
6633 * Implemented the KICK command into server and client.
6635 * Added `query' argument to the silc_idlist_get_client function
6636 to indicate whether to query the client from server or not if
6639 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6640 to indicate that the client is not channel founder.
6644 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Removed the rng context from SilcPacketContext structure and
6647 changed that the packet routine uses the Global RNG API.
6649 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Added support for quit message that client can "leave" on the
6652 channel when it quits the SILC. It is ditributed inside the
6653 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6655 Added silc_server_free_client_data that will take the
6656 signoff message as argument.
6658 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6660 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6662 * Updated parts of the protocol specification to keep it up
6665 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6668 payloads in one packet.
6670 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6671 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6672 use now the new List flag.
6674 * Also deprecated the following packet types: REPLACE_ID,
6675 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6677 * Added list support for Notify packet in server.
6679 * Added silc_server_send_notify_channel_change to send the
6680 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6681 the silc_server_send_replace_id.
6683 * Added silc_server_send_notify_nick_change to send the
6684 NICK_CHANGE notify type. Deprecates the function
6685 silc_server_send_replace_id.
6687 * Added silc_server_send_notify_join to send the JOIN notify type.
6688 Deprecates the function silc_server_send_new_channel_user.
6690 * Added silc_server_send_notify_leave to send LEAVE notify type.
6691 Deprecates the function silc_server_send_remove_channel_user.
6693 * Added silc_server_send_notify_cmode and
6694 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6695 types. Deprecates the silc_server_send_set_mode function.
6697 * Added SERVER_SIGNOFF notify type to indicate that server has
6698 quit. This means that all clients on the channel from that
6699 server will drop. This can be also used when netsplit happens.
6701 Deprecated REMOVE_ID packet type since it is not needed anymore
6704 Added silc_server_send_notify_server_signoff to send the
6705 SERVER_SIGNOFF notify type. Deprecates the function
6706 silc_server_send_remove_id.
6708 Added also silc_server_send_notify_signoff to send the
6709 SIGNOFF notify type.
6711 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6712 SILC protocol from this day on. Changed the protocol
6713 specification as well.
6715 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6716 notify type. It is used between routers to notify about
6717 topic changes on a channel.
6719 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6722 * Partly updated the protocol specification to comply with the
6723 changes now made. It is still though a bit outdated.
6725 * The JOIN notify type now takes one extra argument <Channel ID>.
6726 The packet used to be destined to the channel but now the
6727 JOIN type may be sent as list thus it is impossible to
6728 destine it to any specific channel. By adding this argument
6729 it is again possible.
6731 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6733 * Added CREDITS file. The CHANGES and CREDITS file will appear
6734 in the distribution as well.
6736 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6738 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6739 types in the server's silcd/packet_receive.c.
6741 * Implemented CMODE and CUMODE to work in router environment.
6743 * Fixed minor encoding and decoding buglet from the
6744 lib/silccore/silcmode.c.
6746 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6749 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6751 * Changed all SilcConfigServer* and silc_config_server* to
6752 SilcServerConfig* and silc_server_config*, respectively.
6755 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Associated the ID (client or server ID) to the Authentication
6758 Payload to avoid any possibility of forging. Updated the
6759 protocol specification and the code accordingly.
6761 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * The RSA key length is now save to the RsaKey context in the
6764 key generation process in lib/silccrypt/rsa.c. The key length
6765 is now used to figure out the maximum size of the block allowed
6766 to be encrypted/signed.
6768 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6769 is equivalent to the silc_mp_mp2bin but does not allocate any
6772 * Changed silc_mp_mp2bin API to take length argument. If it is
6773 non-zero then the buffer is allocated that large. If zero, then
6774 the size is approximated using silc_mp_sizeinbase, which however
6777 * Created Global RNG API which is global RNG that application can
6778 initialize. After initializing, any routine anywhere in the
6779 code (including library) can use RNG without allocating a new
6780 RNG object. This was done to allow this sort of use of the
6781 RNG in code that has no chance to allocate RNG object. All
6782 applications currently allocate this and many routines in the
6783 library use this. Affected file lib/silccrypt/silcrng.[ch].
6785 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6786 it to use the Global RNG API.
6788 * Defined Authentication Payload into protocol specification that
6789 is used during SILC session to authenticate entities. It is
6790 used for example by client to authenticate itself to the server
6791 to obtain server operator privileges.
6793 Implemented this payload into the lib/silccore/silcauth.[ch].
6794 Implemented also routines for public key based authentication
6795 as the new protocol specification dictates.
6797 Moved definitions of different authentication methods from
6798 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6800 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6801 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6802 silc_pkcs_verify_with_hash functions into the file
6803 lib/silccrypt/silcpkcs.[ch].
6805 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * The client entry's userinfo pointer must be always valid.
6808 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6809 will fail since it requires the userinfo. Now, the userinfo
6810 is allocated as "" if actual userinfo does not exist. Actually,
6811 it must exist and it is totally Ok to drop client connections
6812 that does not announce the userinfo. However, we will make
6813 this workaround for now.
6815 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6816 to return the remote port by socket.
6818 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6820 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6821 SILC_SERVER_PENDING_EXEC and added an new macro
6822 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6823 data or when error occurs while processing the pending command.
6825 Added new argument `destructor' into silc_server_command_pending
6826 and to the SilcServerCommandPending object. This destructor is
6827 now called after calling the pending callback or if error occurs
6828 immediately. If error occurs the actual pending callback won't
6829 be called at all - only the destructor. The destructor may be
6830 NULL if destructor is not needed.
6832 All this applies for client library code as well. Similar
6833 changes were made there as well for the pending commands.
6835 In the client, the application must now allocate the
6836 SilcClientCommandContext with the silc_client_command_alloc
6839 * Added reference counter to the SilcServerCommandContext. Added
6840 function silc_server_command_alloc and silc_server_command_dup
6843 Same type of functions added to the client library for the same
6846 * Removed the cmd_ident from IDListData away since it is now
6847 global for all connections. It is the command identifier used
6848 in command sending and with pending commands. The affected file
6851 * Added reference counter to the SilcSocketConnection objecet to
6852 indicate the usage count of the object. The object won't be
6853 freed untill the reference counter hits zero. Currently only
6854 server uses this, and client ignores it. The client must be
6855 set to use this too later. The affected files are
6856 lib/silccore/silcsockconn.[ch]. Added also the function
6857 silc_socket_dup to increase the reference counter.
6859 This was mainly added because it is possible that the socket
6860 is removed underneath of pending command or other async
6861 operation. Now it won't be free'd and proper DISCONNECTING
6862 flags, etc. can be set to avoid sending data to connection that
6863 is not valid anymore.
6865 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6866 the connection. After that it sets SILC_SET_DISCONNECTED.
6867 It is, however, possible that the socket data is not still freed.
6868 The silc_server_packet_process now checks that data is not
6869 read or written to connection that is DISCONNECTED. The socket
6870 get's freed when the reference counter hits zero.
6872 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Changed the client operation API: channel_message operation's
6875 `sender' is now the client entry of the sender, not the nickname
6876 and the `channel' is the channel entry, not the channel name.
6878 In the private_message operation the `sender' is now also the
6879 client entry of the sender not the nickname.
6881 Affected file is lib/silcclient/ops.h and all applications
6882 using the client operations.
6884 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6886 * Moved the calling of ops->connect() from connect_to_server_final
6887 into receive_new_id functin since that is the point when the
6888 client is actually allowed to send traffic to network. The
6889 affected file is lib/silcclient/client.c.
6891 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6893 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6894 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6895 (if needs broadcasting) instead of broadcasting the packets one
6896 by one which would make a burst in the network traffic.
6898 * Added `broadcast' argument to the functions in silcd/server.[ch]
6899 silc_server_create_new_channel[_with_id] to indicate whether
6900 to send New Channel packet to primary router.
6902 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6904 * Added new function into the silcd/server.[ch] files:
6905 silc_server_create_new_channel_with_id to create new channel with
6906 already existing Channel ID.
6908 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6909 lib/silccore/silcpacket.h. This packet is used t send list of
6910 Set Mode payloads inside one packet. Server uses this to set
6911 the modes for the channels and clients on those channels, that it
6912 announced to the router when it connected to it. The protocol
6913 specification has been updated accordingly.
6915 * The silc_server_new_channel did not handle the packet coming
6916 from normal server as it normally does not send that. However,
6917 when it announces its channels it does send it. Implemented
6918 the support for that.
6920 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6921 into the file lib/silccore/id.h.
6923 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Fixed memory leaks in the functions silc_idlist_del_client,
6926 silc_idlist_del_channel and silc_idlist_del_server in the file
6927 silcd/idlist.c. All of those leaked like a sieve.
6929 * Fixed some small memory leaks in the client's function
6930 silc_client_notify_by_server.
6932 * Added functions into silcd/server.c: silc_server_announce_clients,
6933 silc_server_announce_channels and silc_server_announce_server.
6934 These functions are used by normal and router server to announce
6935 to its primary router about clients, channels and servers (when
6936 router) that we own. This is done after we've connected to the
6939 These functions effectively implements the following packet types:
6940 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6941 and SILC_PACKET_NEW_ID_LIST.
6943 * Added new functions into the silcd/packet_receive.[ch]:
6944 silc_server_new_id_list, silc_server_new_channel_list and
6945 silc_server_new_channel_user_list to handle the incoming
6946 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6948 * Added support of changing Channel ID in the function
6949 silc_server_replace_id. If the server that announces a channel
6950 to the router already exists in the router (with same name but
6951 with different Channel ID), router is responsible to send
6952 Replace ID packet to the server and force the server to change
6953 the Channel ID to the one router has.
6955 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6956 client that the Channel ID has been changed by the router. The
6957 normal server sends this to the client. Client must start using
6958 the new Channel ID as the channel's ID.
6960 Implemented handling of this new type into lib/silcclient/client.c
6961 into the function silc_client_notify_by_server.
6963 * Added new function silc_idlist_replace_channel_id into the files
6964 silcd/idlist.[ch] to replace the Channel ID.
6966 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6968 * Call silc_server_command_identify_check always when processing
6969 the IDENTIFY command in silcd/command.c
6971 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6974 send keepalive packets. The packet can be sent by clients,
6975 servers and routers.
6977 Added function silc_socket_set_heartbeat into the file
6978 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6979 If not set, the heartbeat is not performed. The actual
6980 heartbeat is implemented in the low level socket connection
6981 library. However, application is responsible of actually
6984 Added silc_server_send_heartbeat to send the actual heartbeat
6985 packet into silcd/packet_send.[ch]. Server now performs
6986 keepalive with all connections.
6988 * Added silc_task_get_first function into lib/silcutil/silctask.c
6989 to return the timeout task with shortest timeout. There was a bug
6990 in task unregistration that caused problems. TODO has been
6991 updated to include that task system must be rewritten.
6993 * The client library will now resolve the client information when
6994 receiving JOIN notify from server for client that we know but
6995 have incomplete information.
6997 * Rewrote parts of silc_server_remove_from_channels and
6998 silc_server_remove_from_one_channel as they did not remove the
6999 channel in some circumstances even though they should've.
7001 * Encryption problem encountered in server:
7003 The LEAVE command used to send the Channel Key packet to the
7004 router immediately after generating it. However, the code
7005 had earlier sent Remove Channel user packet but not immediately,
7006 ie. it was put to queue. The order of packets in the router
7007 was that Channel Key packet was first and Remove Channel User
7008 packet was second, even though they were encrypted in the
7009 reverse order. For this reason, MAC check failed. Now, this
7010 is fixed by not sending the Channel Key packet immediately but
7011 putting it to queue. However, this is more fundamental problem:
7012 packets that are in queue should actually not be encrypted
7013 because packets that are sent immediately gets encrypted
7014 actually with wrong IV (and thus MAC check fails). So, packets
7015 that are in queue should be encrypted when they are sent to
7016 the wire and not when they put to the queue.
7018 However, the problem is that the current system has not been
7019 designed to work that way. Instead, the packet is encrypted
7020 as soon as possible and left to the queue. The queue is then
7021 just purged into wire. There won't be any fixes for this
7022 any time soon. So, the current semantic for packet sending
7025 o If you send packet to remote host and do not force the send
7026 (the packet will be in queue) then all subsequent packets to the
7027 same remote host must also be put to the queue. Only after the
7028 queue has been purged is it safe again to force the packet
7031 o If you send all packets immediately then it safe to send
7032 any of subsequent packets through the queue, however, after
7033 the first packet is put to queue then any subsequent packets
7034 must also be put to the queue.
7036 Follow these rules and everything works fine.
7038 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Added new function silc_server_remove_clients_by_server to
7041 remove all client entries from ID list when the server connection
7042 is lost. In this case it is also important to invalidate all
7043 client entires as they hold the invalid server entry. This
7044 fixes fatal bug when server has lost connection and will reconnect
7047 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7049 * Made some sanity checks to silc_server_daemonise like to check
7050 whether the requested user and group actually exists.
7052 * Added sanity check to SKE's silc_ske_responder_finish to check
7053 that the public and private key actually is valid.
7055 * Invalidate the client's nickname when receiving Replace ID
7056 packet and the Client ID is being replaced. This means that the
7057 server will query the nickname if someone needs it (client)
7060 * Sort the ID Cache in client library when the ID Cache data
7061 has changed (needs sorting).
7063 * Do not allow for SILC client to create several connections to
7064 several servers. The client does not support windows right now
7065 and generating multiple connections causes weird behaviour.
7067 Irssi-silc client does support windows and can handle several
7068 connections without problems, see: www.irssi.org and SILC plugin.
7070 * Fixed some places where client was added to the IDList. The
7071 rule of thumb is following (in order to get everything right):
7072 If the client is directly connected local client then the
7073 `connection' argument must be set and `router' argument must be
7074 NULL to silc_idlist_add_client function. If the client is not
7075 directly connected client then the `router' argument must
7076 bet set and the `connection' argument must be NULL to the
7077 silc_idlist_add_client function.
7079 * The funtion silc_server_packet_send_local_channel actually did
7080 not check whether the client was locally connected or not. It
7081 does that now. Fixed a bug related to LEAVE command.
7083 * Fixed Remove Channel User payload parsing bug in server's
7084 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7086 * The server's silc_server_save_channel_key now checks also the
7087 global ID list for the channel as it might not be in the local
7088 list. Fixed a bug related to LEAVE command.
7090 * Is this the end of the [<unknown>] buglet that has been lurking
7091 around for a long time? A little for loop fix in server's
7092 silc_server_command_whois_parse that is used by both IDENTIFY
7093 and WHOIS command. At least, this was a clear bug and a cause
7094 of one type of [<unknown>] buglet.
7096 * WHOIS and IDENTIFY commands call the function
7097 silc_server_command_[whois/identify]_check function even if
7098 we are not router server.
7100 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Added --with-gmp configuration option. If set the GMP
7103 is always compiled in the SILC source tree. If not set then
7104 it is checked whether the system has the GMP3 installed. If
7105 it has then the GMP won't be compiled (the system's headers
7106 and library is used), if it doesn't have it then the GMP is
7107 compiled in the SILC source tree.
7109 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Changed RSA private exponent generation to what PKCS #1
7112 suggests. We try to find the smallest possible d by doing
7113 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7114 not security fix but optimization.
7116 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Added new config entry [Identity] to fork the server and run
7119 it as specific user and group. A patch from Bostik.
7121 * Imported Dotconf configuration library into lib/dotconf.
7122 This will be used to create the SILC configuration files later.
7123 It will appear in the distsribution after this commit.
7125 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * A big code auditing weekend happening. Auditing code for
7128 obvious mistakes, bugs and errors. Also, removing any code
7131 Removed files for being obsolete:
7133 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7134 inline in the file lib/silcutil/silcbuffer.h)
7136 o lib/silcutil/silcbufutil.c (the header has inline versions)
7138 Changed code to fix possible error conditions:
7140 o The buffer formatting routines now check that the destination
7141 buffer really has enough space to add the data. This applies for
7142 both buffer formatting and unformatting
7143 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7144 unformatting was changed to accomodate following rules:
7145 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7146 sent to the function while XXX_*STRING will not allocate or copy
7147 the data into the buffer. Instead it sets the pointer from the
7148 buffer into the pointer sent as argument (XXX_*STRING used to
7149 require that the pointer must be allocated already). This change
7150 makes this whole thing a bit more consistent and more optimized
7151 (note that the data returned in the unformatting with XXX_*STRING
7152 must not be freed now). The routines return now -1 on error.
7154 o Tried to find all code that use buffer_format and buffer_unformat
7155 and added return value checking to prevent formatting and
7156 especially unformatting errors and possible subsequent fatal
7159 o Changed ske->x and ske->KEY to mallocated pointers in
7160 lib/silcske/silcske.h. Fixed possible data and memory leak.
7162 o Added return value checking to all *_parse* functions. Fixed
7163 many memory leaks as well.
7165 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7166 so that buffer overflows would not happen. All code now also
7167 checks the return value as it can fail.
7169 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Added reconnection support to server if the normal server looses
7172 its connection to the router (for example if router is rebooted).
7173 The server performs normal reconnection strategy implemented
7174 to the server. Affected file silcd/server.c.
7176 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added new packet type SILC_PACKET_SET_MODE that is used to
7179 distribute the information about changed modes (for clients,
7180 channels and clients channel modes) to all routers in the
7181 network. Updated the protocol specification accordingly.
7183 Added functions into silcd/packet_send.c and
7184 silcd/packet_receive.c: silc_server_send_set_mode,
7185 silc_server_set_mode.
7187 Added new files silcmode.[ch] into lib/silccore that implements
7188 the encoding and decoding of Set Mode Payload. Added new type
7189 SilcSetModePayload. Moved the definitions of different modes
7190 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7192 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Oops, a little mistake in server's connection authentication
7195 protocol. The protocol is not ended with FAILURE but with
7196 SUCCESS if the authentication is Ok. :) Affected file is
7199 * Implemented NICK_CHANGE notify handling in server in the file
7200 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7201 the local clients on the channel. After the changing nickname
7202 in router environment snhould work and the [<unknown>] nickname
7203 should appear no more.
7205 The silc_server_replace_id function that receives the Replace ID
7206 payload now sends the NICK_CHANGE notify type also in the file
7207 silcd/packet_receive.c
7209 * Changed WHOIS and IDENTIFY command to support the maximum amount
7210 of arguments defined in protocol specs (3328 arguments). This
7211 fixed a bug that caused problems when there were more than three
7214 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Added extra parameter, command identifier, to the
7217 silc_client_send_command so that explicit command identifier
7220 Changed that ID list routines uses specific command identifier
7221 when sending WHOIS/IDENTIFY requests to the server so that they
7222 can be identified when the reply comes back.
7224 Affected files lib/silcclient/command.[ch],
7225 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7227 * Added `sender' argument to silc_server_packet_send_to_channel
7228 to indicaet the sender who originally sent the packet to us
7229 that we are now re-sending. Ignored if NULL. Affected file
7230 silcd/packet_send.[ch].
7232 * Added some server statistics support in silcd/server_internal.h
7233 SilcServerStatistics structure and around the server code. Also
7234 send some nice statistics information when client is connecting
7237 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Fixed channel ID decoding in server's JOIN command reply in
7240 silcd/command_reply.c
7242 * Fixed braodcasting of replace ID payload to not to send it if
7243 we are standalone server in silcd/packet_receive.c.
7245 * Fixed all channel message sending routines to not to send
7246 packets to clients that has router set, since they are routed
7247 separately in the same function earlier. Affects file
7248 silcd/packet_send.c and all channel packet sending functions.
7250 * In USERS reply, res_argv[i] are not allocated, the table
7251 is allocated. Thus changed that free the table, not its
7254 * In server's whois_check and identify_check if the client is
7255 locally connected do not send any WHOIS commands - they are not
7258 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7260 * Fixed some minor bugs in client when sending WHOIS command. The
7261 arguments was in wrong order.
7263 * Removed statis function add_to_channel from server in
7264 silcd/command.c that was previously used with the joining but
7267 * Tested USERS command in router environment successfully with two
7268 routers, two servers and two clients.
7270 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7272 * Reorganized the USERS command and command reply in client library
7273 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7274 When the command is given by user we register a pending command
7275 callback that will reprocess the command after the reply has been
7276 received from the server. When reprocessing the packet we then
7277 display the information. Thus, the USERS information is displayed
7278 now in the command callback instead of in the command reply
7279 callback. The processing of the command is same as previously
7280 when server has sent the command reply in the JOINing process.
7282 * Added to USERS command in silcd/command_reply.c to join the client,
7283 we didn't use to know about, to the channel after we've created
7284 a client entry for it. Also, for clienet we did know already still
7285 check whether it is on the channel or not and add it if not.
7287 * Removed silc_server_command_join_notify as the function and its
7290 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Changed the client's pending command handling to the same as the
7293 server's pending command handling. It is also now possible to
7294 execute command reply functions from other command reply
7295 function as the function callbacks for commands and command
7296 replies are one and same. The pending commands are not static
7297 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7298 in client connection context. Thus, pending commands are server
7299 connection specific as it is convenient.
7301 Changed the function silc_client_command_pending and
7302 silc_client_command_pending_del and added new function
7303 silc_client_command_pending_check. Removed the
7304 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7307 * Added cmd_ident, current command identifier, to the client
7308 connection context in lib/silcclient/client.h to keep track on
7309 command identifiers used in command sending. Client's command reply
7310 function handling now supports the mandatory command identifiers.
7312 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7313 funtions in client to fully support pending command callbacks.
7315 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7316 as one of the arguments to the application in the command reply
7319 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7320 before first releasing SILC but came back. Now it is removed again
7321 and should come back nomore. The FORWARDED flag was used only
7322 by the JOINing procedure by forwarding the command packet to router.
7323 Now, the JOINing procedure has been changed to more generic (due
7324 to various router environment issues) and FORWARDED is not needed
7325 anymore for anything. The protocol specification is yet to be
7328 Now, removed silc_server_packet_forward from server and the flag
7329 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7331 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Renamed NAMES command to USERS command. The NAMES was named that
7334 due to historical reasons. Now it is renamed. Also, rewrote
7335 parts of the USERS command. The nickname list is not sent anymore
7336 by the server. Only Client ID and mode lists are sent in the USERS
7337 command. Changed this also to the protocol specification.
7339 The client now resolves the names and stuff after it receives
7340 the USERS list from the server when joining to the channel.
7342 * WHOIS and IDENTIFY commands has been changed to support multiple
7343 Client ID's per command. One can now search for multiple users
7344 in the network by sending only one WHOIS or IDENTIFY command.
7345 Changed the code and the protocol specifications.
7347 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7348 uses silc_server_command_whois_parse to parse the request. */
7350 * If normal server, do not parse the WHOIS and IDENTIFY requests
7351 before sending it to the router. Saves some time.
7353 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7355 * Fixed JOIN command on client library. Wrong number of arguments
7356 used to crash the client.
7358 * Added silc_server_channel_has_global function to check whether
7359 channel has global users or not.
7361 * Added silc_server_channel_has_local function to check whether channel
7362 has locally connected clients on the channel.
7364 * The silc_server_remove_from_one_channel now checks whether the
7365 channel has global users or not after given client was removed from
7366 the channel. It also checks whether the channel has local clients
7367 on the channel anymore. If it does not have then the channel entry
7368 is removed as it is not needed anymore.
7370 * The silc_server_notify now checks on JOIN notify whether the joining
7371 client is one of locally connected or global. If it is global then
7372 the channel has now global users on the channel and that is marked
7373 to the channel entry. Also, it now saves the global client to
7374 global list who is joining and JOINs it to the channel. This is
7375 for normal server, that is.
7377 Changed silc_server_send_notify_on_channel,
7378 silc_server_packet_relay_to_channel and
7379 silc_server_packet_send_to_channel check if we are normal server
7380 and client has router set (ie. global client) do not send the
7381 message to that client, as it is already routed to our router.
7383 * Implemented LEAVE notify type handling in silc_server_notify
7386 * Tested LEAVE command in router environment successfully. Tested
7387 with two routers, two servers and two clients.
7391 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7393 * Implemented SIGNOFF notify type handling in silc_server_notify
7396 * silc_server_remove_id now removes the client entry from all channels
7397 it has joined and thusly sends SIGNOFF notify type.
7399 * Rewrote the NAMES list generation in server by removing two excess
7400 loops. The lists are created now inside one loop.
7402 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7404 * silc_server_remove_channel_user checks now also global list
7405 for channel and client.
7407 * silc_server_new_channel_user checks now both local and global
7408 list for channel and client. Fixed a bug in client id decoding.
7409 Used to decode wrong buffer.
7411 * silc_server_channel_message checks now both local and global
7412 list for channel entry.
7414 * Tested channel joining (hence JOIN) in router environment
7415 successfully. Tested with two routers, two servers and two
7418 * Tested channel message sending in router environment successfully.
7420 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Added silc_server_save_channel_key into server.[ch] to save the
7423 received channel key in Channel Key payload processing. It is
7424 also used in JOIN command reply handling.
7426 Equivalent function silc_client_save_channel_key added into
7427 client.[ch] into client library.
7429 * Changed JOIN command reply to send information whether the channel
7430 was created or not (is existing already) and the channel key
7431 payload. Changed protocol specs accordingly.
7433 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7434 the request was sent by ID and not by nickname. Crashed on
7437 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7440 now correctly save the received data.
7442 * silc_server_free_sock_user_data now notifies routers in the
7443 network about entities leaving the network.
7445 At the same time implemented functions silc_server_remove_id
7446 and silc_server_send_remove_id to receive and send REMOVE_ID
7447 packets. The packet is used to notify routers in the network
7448 about leaving entities. The ID removed will become invalid in
7451 * Added function silc_idlist_del_server into server. Removes and
7452 free's server entry from ID list.
7454 * silc_server_private_message function now checks, if we are router,
7455 that the destination ID really is valid ID, naturally.
7457 * In router when NEW_ID packet is received (for new client) the
7458 hash of the Client ID is saved in the ID Cache but the
7459 client->nickname is set to NULL, instead of putting the hash
7462 IDENTIFY command now also checks that client->nickname must be
7463 valid. If it is not if will request the data from the server who
7464 owns the client. Added new function
7465 silc_server_command_identify_check.
7467 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7468 to set the command to already allocated Command Payload.
7470 * Tested private message sending in router environment with two
7471 routers, two servers and two clients. Fixed minor bugs and now
7474 * Fixed segfault from client's NAMES command. Used to crash if
7477 * Forwarded packets must not be routed even if it is not destined
7478 to the receiver. Changed server code comply with this.
7480 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7482 * Added `require_reverse_mapping' boolean value to ServerParams
7483 structure. If TRUE (not default) the server will require that
7484 the connecting host has fully qualified domain name.
7486 If the reverse mapping is not required and hostname could not be
7487 found the IP address is used as hostname.
7489 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7491 * Implemented version string checking to both client and server.
7492 The check is incomplete currently due to the abnormal version
7493 strings used in development version of SILC.
7495 * Changed all command functions in server to use the new
7498 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Changed char *data to unsigned char *data in ID Cache system to
7501 support binary data as ID Cache data. Changed code to support
7502 binary data in lib/silccore/idcache.c.
7504 * Renamed silc_server_packet_relay_command_reply to
7505 silc_server_command_reply as it is normal packet receiving
7506 function. Rewrote the function to accept command replys for
7507 servers and not only for clients.
7509 * Mark remote router always as registered server if we are connecting
7510 to it. Otherwise, commands sent by the router to us are ignored.
7512 * All ID List find routines now returns the ID Cache Entry pointer
7513 as well if requested.
7515 * WHOIS command works now in router environment, tested with two
7516 routers, two servers and two clients.
7518 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7519 in router environment (as it is almost equivalent to WHOIS) but
7520 hasn't been tested thoroughly. Added new functions:
7522 silc_server_command_identify_parse
7523 silc_server_command_identify_send_reply
7524 silc_server_command_identify_from_client
7525 silc_server_command_identify_from_server
7527 * Disabled route cache adding because adding two different ID's with
7528 same IP replaces the old cache entry thus giving wrong route.
7529 The entry->router->connection is always the fastest route anyway
7530 so route cache may not be needed. Of course, new routes maybe
7531 established after receiving the ID when the entry->router->connection
7532 might not be anymore the most optimal.
7534 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7536 * Add route cache for received ID for fast routing.
7538 * Added silc_server_packet_route to route received packet on router
7539 that is not destined to us.
7541 * Renamed silc_server_get_route to silc_server_route_get.
7543 * Added id_string and id_string_len fields into SilcServer to
7544 include encoded ServerID for fast comparing without excess
7545 encoding of the ID's.
7547 * Cleaned up WHOIS command on server side. Added following static
7550 silc_server_command_whois_parse
7551 silc_server_command_whois_check
7552 silc_server_command_whois_send_reply
7553 silc_server_command_whois_from_client
7554 silc_server_command_whois_from_server
7556 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7557 arguments in command replies. All command functions should be
7558 updated to use this macro.
7560 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * Minor typo fixes on command reply handling on server.
7564 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7566 * Added silc_server_command_add_to_channel internal routine to add
7567 the client to the channel after router has created the channel and
7568 sent command reply to the server.
7570 * Added generic silc_server_send_command to send any command from
7573 * Use static buffer with ID rendering instead of duplicating data.
7575 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7577 * Fixed a channel user mode bug when joining to a channel server gave
7578 everybody channel founder rights, oops.
7580 * We mark ourselves as the router of the incoming server connection
7581 if we are router ourselves. This way we can check in some packet
7582 sending functions whether it is locally connected server. For
7583 incoming router connections we put NULL.
7585 * For router sending packets locally means now always sending the
7586 packet cell wide; to local clients and local servers. For normal
7587 server sending packet locally means sending it to only local
7590 * Fixed the JOIN command to really work in router environment. If the
7591 channel is created it is always created by the router. Router is
7592 also responsible of making the initial joining to the channel,
7593 sending JOIN notify to the sending server and distributing
7594 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7595 does not exist server doesn't do anything else but forward the
7596 command to the router which performs everything.
7598 * Added silc_server_send_channel_key function to send the Channel Key
7601 * Added silc_server_create_channel_key to create new channel key. The
7602 channel key is now re-generated everytime someone joins or leaves
7603 a channel, as protocol dictates. Note: channel->key_len is the
7606 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7608 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7609 packet_receive.[ch] to separate packet sending and receiving
7610 routines. The server.[ch] now includes everything else including
7611 actual packet processing (writing and reading data) and other
7614 Renamed silc_server_private_message_send_internal to
7615 silc_server_send_private_message. The routine is still though
7616 used only to relay private messages as server does not send
7617 private messages itself.
7619 Renamed silc_server_new_channel to silc_server_create_new_channel
7620 and added new function sicl_server_new_channel that handles the
7621 incoming New Channel packet. Added also new sending function
7622 silc_server_send_new_channel to send New Channel Payload.
7624 * Added new function silc_server_notify to process incoming notify
7625 packet to the server/router. Server may then relay the notify
7626 to clients if needed.
7628 * Added new function silc_server_new_channel_user to process incoming
7629 New Channel User packet. Router will redistribute the packet and
7630 send JOIN notify to its local clients and locally connected servers
7631 if needed. Normal server will send JOIN notify to its local client
7632 on same channel when received this packet. Added also corresponding
7633 sending function silc_server_send_new_channel_user to sent the
7636 * Added boolean route argument to send_notif_to_channel and
7637 packet_send_to_channel functions to attempt to route the packet
7638 if it is TRUE and send only locally if it is FALSE.
7640 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * silc_server_replace_id now broadcasts the received replace ID
7643 packet if it is not broadcast packet already. The router must
7644 broadcast to inform other routers about changed ID.
7646 * Added backpointer to server's router into SilcServer context in
7647 silcd/server_internal.h.
7649 * Fixed silc_server_packet_broadcast to send correct broadcast
7652 * The channel key is now distributed to the local client as soon
7653 as it is received from the router (in router environment) so that
7654 no other packet may be sent for the channel until client has
7657 * silc_server_remove_channel_user now broadcasts the received
7658 Remove Channel User packet if it is not broadcast packet already.
7659 The router must broadcast to inform other routers about removed
7662 * Added users field into SilcPacketContext that is a reference count
7663 of the context. One can increase the reference count by calling
7664 silc_packet_context_dup which is now changed to just increase the
7665 reference count instead of duplicating the data. The reference
7666 count is decresed by calling silc_packet_context_free that will
7667 free the data after the reference count hits zero.
7669 For now on the packet context and everything allocated into it
7670 (including the raw packet from network) must be freed by calling
7671 the new silc_packet_context_free function. Added also new function
7672 silc_packet_context_alloc that must be used now to allocate the
7673 context. This also means that if a routine is asynchronous from
7674 silc_[client/server]_packet_parse_type the packet context must
7675 be duplicated by calling silc_packet_context_dup. Otherwise it
7676 gets free'd after silc_[client/server]_packet_parse_type returns.
7677 Also, one must remember that if packet is duplicated then its
7678 reference count must be decresed by calling the free function as
7679 many times as it was duplicated.
7681 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7682 from both client and server.
7684 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * Made joining to a channel working in router environment.
7688 * Cleaned up JOIN command on server side and create function
7689 silc_server_command_join_channel internal routine to make the
7692 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7694 * Changed silc_command_pending list to SilcDList. Also, added
7695 `ident' field to SilcServerCommandPending structure to identify
7696 the reply and to call correct callback.
7698 Added silc_server_command_pending_check function to replace the
7699 corresnponding macro. The silc_command_pending list is not
7702 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7703 to set identifier to previously allocated Command Payload. It
7704 is used to set identifier for command when resending Command
7707 * Added silc_command_payload_encode_payload to encode Command
7708 Payload buffer from SilcCommandPayload structure.
7710 * Added silc_argument_payload_encode_payload to encode Argument
7711 payload buffer from SilcArgumentPayload structure.
7713 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7715 * Changed WHOIS command to support router connection on server side.
7716 The whois request is always sent to router unless the server is
7717 standalone server. After server has received the reply from the
7718 router will it send the reply to the client.
7720 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7721 broadcast received broadcast packet. The function is used only
7722 by router. The broadcast packet is always sent to the router's
7725 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7726 render given ID to printable string, for log files for example.
7728 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Made basic router to router connections working. At least they
7731 can now connect to each other but nothing really works the way
7732 they are supposed - yet.
7734 * Added new initiator token to RouterConnection configuration
7735 file in silcd/serverconfig.[ch]. It is used to tell whether we
7736 are the initiator to the remote router or whether we'll expect
7737 the other end to connect.
7739 * Moved registering of listener task to silc_server_init, hence
7740 the server starts listenning as soon as it is run, even if it
7741 does not have connections to other routers. Let's see how well
7744 * Changed default connection retry timeouts for more suitable in
7747 * Removed cipher and such arguments from silc_idlist_add_client
7748 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7749 Added new function silc_idlist_add_data to add the keys and stuff
7752 * Added SilcIDListData structure and added it to SilcClientEntry
7753 and SilcServerEntry as their first field in the structure. This
7754 way we can explicitly cast the ID entries to the SilcIDListData
7755 structure and get common data for the entries. In past, we had
7756 to first check what type of connection it is and then cast it to
7757 correct ID entry type. Now, we can directly cast the opaque
7758 pointer to the SilcIDListData (no matter what ID entry it actually
7759 is) and get the data needed.
7761 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7763 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7764 in some circumstances even if threre were timeout tasks, though not
7765 IO tasks, but tasks anyway. Now fixed.
7767 * Defined SilcServerConnection structure to hold connection specific
7768 stuff about directly connected servers and routers. The definition
7769 is currently in silcd/server_internal.h. I thought about having
7770 a bit more important role fro this struct but for now it is used
7771 only when connecting to other server (or router actually).
7773 * Added connecting retry support in server when connecting to
7774 router(s). The retry feature implement exponential backoff
7775 algorithm. Also, added SilcServerParams structure to hold default
7776 parameters for server. For now, it include these retry settings
7777 and are hard coded. After server is moded to be as Silc Server
7778 Library this structure will be more important.
7780 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7782 * Changed client librarys channel->clients table to SilcList and
7783 changed code accordingly.
7785 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Changed client's channel table to SilcList and changed code
7788 accordingly. Also changed SilcChannelClientEntry to include back-
7789 pointer to the channel so that client entry can use that structure
7790 as list as well and we have fast cross-reference to the channel.
7791 This change dramatically decreased the complexity of channel
7792 handling with client entry and vice versa (removed one extra
7793 loop when searching for channel entry from many functions).
7795 * Changed server->sim from table to SilcDList and changed code
7798 * NAMES command can now be used from user interface. It will show
7799 the user list on the channel, neatly.
7801 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7802 Code now saves realname of the user if it becomes available.
7804 * Renamed configure.in to configure.in.pre and made ./prepare
7805 script to automatically add correct version string to
7806 configure.in which it creates from configure.in.pre.
7808 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7810 * NAMES command reply now shows users mode with the nickname when
7813 * Moved silc_client_ch[u]mode[_char] functions from
7814 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7815 place sucks, they are utility functions and should be in some
7818 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7820 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7823 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7827 * Added TRQ (efficient deque and list library) into lib/trq. This is
7828 a very good list library that is currently used in the SILC. Defined
7829 SilcList API over the library because I didn't like the API very
7830 much. See lib/trq/silclist.h for the API and examples of how to
7831 use the API. Fixed various places in the code to use the new
7832 SilcList API. The SilcList is meant for lists that has a structure
7833 already defined as a list. It is not suitable to add just some
7834 context to the list (in TRQ, the context is the list actually).
7836 So, I defined SilcDList that can be used for the purpose where
7837 predefined list structure does not exit. This can be used as
7838 such list. Now some context just can be added to the SilcDList.
7839 Currently this list is not used in the SILC just yet, though there
7840 are a lot places where this can replace dynamically allocated
7841 tables and I will fix these places, later, to use SilcDList.
7842 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7843 and use TRQ internally).
7845 Also fixed some annoying warning messages that the original TRQ
7846 code generated. Also minor changes to TRQ's Makefile.in.
7848 * Added support for querying by Client ID to both WHOIS and
7849 IDENTIFY commands into server, as required by the protocol.
7851 * Removed method function pointers from SilcBuffer structure. They
7852 weren't used to anything and just increased the context size for
7853 no good reason. This change also made silc_buffer_alloc and
7854 silc_buffer_free functions inline functions.
7856 * Disabled command flooding detection support until it's fixed so
7857 that it accepts commands in but does not execute them more than once
7860 * Added silc_net_localhost(), to return local hostname, into
7861 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7862 that must be initialized before calling silc_client_init.
7864 * Added new function: silc_server_send_notify_on_channels to send
7865 notify messages to all channels client has joined. It is assured
7866 that the message is sent only once per client.
7868 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7869 lib/silcutil/silcutil.[ch] as silc_format function. The new
7870 function is generic and is used by server as well, not only by
7871 the logging routines.
7873 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7874 the provided version string was not acceptable. Added new function:
7875 silc_ske_check_version into lib/silcske/silcske.h. The function
7876 must be implemented by the application (client or server) and it
7877 does not reside in the SKE library. The function checks the version
7878 string remote end sent.
7880 * Added back pointers (to opaque context and to SilcSocketConnection)
7881 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7883 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7884 duplicate packet context structure.
7886 * Changed `notify' client operation to send same arguments as client
7887 receives from server except for ID's. ID's are mapped to correct
7888 ID entry and that is returned. Also, if channel entry is not sent
7889 by server but the notify is for channel the channel entry is sent
7890 to application (otherwise application doesn't know that it is for
7891 channel (library gets it from packet's Destination ID)).
7893 * Added silc_client_remove_from_channels into client library to
7894 remove a client from all channels it has joined to. Used when
7895 received SIGNOFF notify from server. Added also new function
7896 silc_client_replace_from_channels to replace old ID entry with
7897 new ID entry on all channels. Used when received NICK_CHANGE
7900 * Fixed ID Cache list handling in silc_idlist_get_client in
7901 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7902 to get (or query) client by ID.
7904 * Updated TODO list.
7906 * Added connection authentication status message defined by the
7907 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7908 support for these into the code in client and server side.
7910 * Added generic function silc_client_send_command to send any command
7911 with variable argument list. Application should use this function
7912 to send commands if the command functions provided by the library
7913 does not suite for the application's user interface needs.
7915 * Added new `failure' client operation. Application is notified about
7916 received failure packet if client is executing a protocol. In this
7917 case the protocol's execution has failed.
7919 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7920 is required by the protocol.
7922 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7923 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7926 * Added status flag to SilcSKE object to indicate realtime status
7927 of the SKE protocol.
7929 * Application receives now exactly same command reply arguments as
7930 the library receives from server. However, if ID is received the
7931 corresponding ID entry is returned to the application (eg. Client
7932 ID is mapped to correct SilcClientEntry entry and that is returned).
7933 Changed command_reply client operation due to this change.
7935 * Changed all ID's in commands and in command replys as ID Payloads.
7936 Change affected both client and server side codes.
7938 All ID's sent in SILC network (with execption of ID's in SILC
7939 Packet header) are sent in ID Payload to support variable length
7942 * Server now notifies nick changes and notifies all clients on
7943 the channels about the new nickname (about the new Client ID,
7946 * Implemented CMODE command to change channel modes. Supports all
7947 channel modes defined by the protocol specs except ban and invite
7948 lists. (Also, private channel key mode is supported but support for
7949 setting private channel key in client is missing, thus, this mode
7950 has no effect on client side (except that server requires that the
7951 client uses private channel key and normal channel traffic does not
7954 Also, invite mode works per se, but INVITE command does not work
7955 yet correctly, so you can set channel as invite only channel but
7956 inviting clients to the channel does not work (it is yet to be
7957 thought what's the best way to do it).
7959 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7960 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7961 Implemented CUMODE command to change user's mode on the channel.
7962 Supports all modes defined by the protocol specs.
7964 * Added NAMES command reply to return users modes on the channel.
7966 * Removed unnecessary and slow ciphers from lib/silccrypt.
7968 * Set SO_KEEPALIVE option to connection sockets by default.
7970 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7972 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7973 redefined the Notify Payload into protocol specs.
7975 * Added silc_id_payload_parse_id to get ID directly from raw
7978 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7981 accept searching by Client ID as well.
7983 * Added support for LEAVE and SIGNOFF notify types in client library.
7985 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7986 to parse ID Payload from raw data.
7988 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7990 * Added flags parameter into silc_ske_assemble_security_properties
7991 function in lib/silcske/silcske.[ch].
7993 * Changed notify client operation to fit better for notify messages
7994 sent by server. The notify payload received from server is now
7995 passed to the application (after parsing it to SilcNotifyPayload).
7996 It is application's responsibility to retrieve the arguments
7997 from the payload and show the message the way it wants. The message
7998 sent by server is implementation specific.
8000 * Changed public keys to comply with the protocol specification.
8001 Old public keys are not supported anymore and are not compatible.
8003 * Removed nickname from Channel Payload as the latest draft removed
8004 it. The client must resolve the nickname from the NAMES command
8005 reply received when it joined the channel.
8007 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8009 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Fixed some errors in protocol specification drafts.
8013 * Created lib/silccore/silcnotify.c to implement Notify Payload
8014 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8015 generic payloads described by protocol specifications. The file
8016 includes implementations for ID Payload and Argument Payload.
8018 * Changed Command Payload implementation to use the new Argument
8019 Payload. Changed command_xxxx_payload to command_payload_xxxx
8020 to comply with SILC coding conventions.
8022 * Added suppport for Argument Payload handling in Notify Payload
8023 implementation as protocol requires it. Added the new support
8024 into server and client lib as well.
8026 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Added support for multiple nicknames on same channel. [n] is
8029 added locally to the nickname if there are more than one same
8030 nicknames on the channel.
8032 * Server now sends all nicknames that matched WHOIS request.
8033 Client also shows the list received from server.
8035 * Added TOPIC command to client side. User can now set and show
8036 current topic on channel.
8038 * Added MOTD command to client and server. Also, server sends the
8039 motd when client connects to the server.
8041 * Changed version strings to comply ISO 8601.
8043 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8045 * Fixed protocol error handling in client library. It should now
8046 cope even if the SKE fails for some reason.
8048 * Made new protocol specification drafts for submitting to IETF.
8050 * Implemented TOPIC command to server in silcd/command.c.
8052 * Added two new notify types into lib/silccore/silcnotify.h:
8053 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8054 notify nickname change and topic setting/change on a channel.
8056 * API change of command_reply operation in client library. The
8057 application gets now the status type received from server as well.
8059 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8061 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8063 * Cras fixed and optimized the packet handling even further and
8064 it should work now. Minor change to the prototype of function
8065 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8067 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Added new function into lib/silcutil/silcschedule.[ch]:
8070 silc_schedule_with_fd to select() a specified fd. The function
8071 returns after timeout expires or data arrives or goes. The
8072 function is used by packet routines to wait that all data is
8073 received from network.
8075 * Fixed data reading from network in lib/silccore/silcpacket.c.
8076 The code now assures that all data is read from the fd and then
8077 continues packet processing. This was a bug fix since the code
8078 used to drop some data in some circumstances.
8080 * Added new function into lib/silcclient/client.[ch]:
8081 silc_client_start_key_exchange to start key exchange after
8082 connection has been established to server. The code internally
8083 now uses this funtion but its main purpose was to provide it
8084 for applications that perform their own connecting. After
8085 application has created a connection it merely calls this
8086 function to start the key exchange between client and server.
8087 The library takes care of everything else after that.
8089 Updated also lib/silcclient/README to explain the usage of
8092 * Do not send to application information that connection has
8093 been established. Application gets notified it by connect
8096 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8098 * Applied cras's patch to add silc_schedule_one function. The
8099 function runs scheduler once and returns.
8101 * Fixed the scheduler after cras messed it up. The timeout
8102 handling works now as it's supposed to work.
8104 * Added into lib/silccore/ silcnotify.h to include notify
8105 message types support. Changed silc_server_send_notify*
8106 functions, in server.[ch], to support those new notify types.
8107 Added the support for the notify types into client library,
8108 as well. Added new notify client operation into ops.h in
8111 * Changed silc_server_packet_send_to_channel to send normal
8112 packets instead of just channel message packets. The function
8113 is now used to send the notify packets to channels. It is not
8114 used to send channel message packets anymore, as server never
8117 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8118 va_arg()s as it seems to require it nowadays. I guess, if SILC
8119 is compiled with older va_arg() the new code should work anyway.
8121 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * Splitted core library. Core library (lib/silccore) includes
8124 now only SILC protocol specific core (and common) components.
8125 Created new utility library (lib/silcutil) that includes more
8126 generic purpose stuff. The stuff for util library was taken
8127 from the old core library. This was minor and easy split.
8129 * Created SILC Client Library (lib/silcclient) that includes
8130 implementation of the SILC client without user interface. This
8131 was major move from silc/ directory. The code has been changed
8132 so that it is transparent towards the user interface. The
8133 silc/ directory includes now the same user interface as before
8134 and it uses the new client library. Read lib/silcclient/README.
8135 Basicly, the client library performs everything else related
8136 to SILC except user interface handling. Also, configuration
8137 files are considered to be part of user interface and library
8138 does not handle them.
8140 This change also changed a lot of structures, function naming etc.
8141 Most important change was that SilcClientWindow object was
8142 renamed to SilcClientConnection in the client library. Created
8143 also new file lib/silcclient/ops.h. Also added new files
8144 silc/local_command.[ch] and silc/client_ops.[ch].
8146 All these changes were made to make it easier for user interface
8147 designers to create what ever user interface for the SILC client
8150 It is also expected that the server will be moved to lib
8151 directory as well and SILC Server Library will be created;
8152 sometimes in the future.
8154 * Removed Local commands from lib/silccore/silccommand.h as
8155 they are application specific and new client library does not
8156 handle any of those anymore.
8158 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8159 old client implementation in silc/.
8161 * Added support for callback functions in SILC_LOG_* macros.
8162 Application can now set its own callbacks that will be called
8163 instead of using the default functions that will always print
8164 the debug messages to stderr (or stdout). Also, debugging can
8165 now be disabled by setting silc_debug to FALSE and re-enabled by
8166 setting it to TRUE. Note, that logging will still work even
8167 if debugging is disabled.
8169 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8170 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8171 silc_log_reset_debug_callbacks.
8173 * To enable debugging in silc client one must give now -d
8174 option on command line.
8176 * Changed silc_schedule_init to automatically allocate task queues
8177 if they are not allocated before calling it.
8179 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8181 * Added GMP 3.1 into math library.
8183 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8186 a channel in SILC network. The packet is used by servers and
8187 routers to notify other routers that user has left a channel.
8188 This little feature was missing until now. Added the feature
8189 to protocol specification as well.
8191 Added functions: silc_server_send_remove_channel_user and
8192 silc_server_remove_channel_user into server.[ch].
8194 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8195 lib/silccore/silcpacket.h. However, they are not implemented
8198 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8200 * Fixed joining to a channel and sending channel messages
8201 between server and router. The channel message sending should
8202 now work inside a cell.
8204 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8206 * Fixed the private message sending between server and router.
8207 The private message sending should now work inside a cell.
8209 * Added silc_server_replace_id into server.[ch] to replace
8210 existing ID in the SILC network.
8212 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8213 and silc_idlist_replace_server_id into idlist.[ch] in server.
8215 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8217 * Fixed the server to server connections. Server can again now
8218 connect to router. Router to router connections probably does
8221 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Added dynamic protocol registering support. Now protocols can
8224 registered and unregistered on the fly. Patch by cras.
8226 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8228 * Added lib/contrib directory to hold routines that some platforms
8229 don't have but are needed by SILC.
8231 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8232 into lin/contrib to provide getopt() and getopt_long() for
8233 those who don't have it.
8235 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8237 * Added AWAY command to client. When away message is set and
8238 client receives a private message packet the client automatically
8239 replies to the sender with the away message.
8241 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8242 bug seemed to be the cause of recent problems when compiling
8245 * Added version detection support to SKE protocol specification
8246 and added the new changes to the SKE implementation as well.
8247 There were other minor changes in the SKE protocol as well.
8249 Many changes in lib/silcske/silcske.[ch] and in
8250 lib/silcske/payload.[ch].
8252 * Added ^U functionality, clear input line. Patch from cras.
8254 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8256 * Mainly small bugfixes on core library. Fixed some debugging
8257 logging and buffer overflow in silclog.c.
8259 * Updated config.sub and config.guess on the distribution tree.
8261 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added command lagging support in server. Client may execute
8264 commands now only once in two seconds.
8266 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8268 * Optimized packet reception. MAC computation and checking is now
8269 also more optimized. A lot previously duplicated code is now
8270 used as generic by both client and server.
8272 * Fixed key pair generation in clientutil.c
8274 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8276 * Added into lib/silccore/silcbufutil.[ch] new function;
8277 silc_buffer_realloc.
8279 * Moved generic packet sending/encryption functions to
8280 lib/silccore/silcpacket.[ch] from client and server. Some
8281 rewriting of the functions.
8283 * Moved all generic packet reception/decryption functions to
8284 lib/silccore/silcpacket.[ch] from client and server. The
8285 packet processing is now much cleaner in both client and server.
8286 These were major changes in both client and server.
8288 * Created many common functions in server to do packet sending.
8289 Previously code were duplicated a lot, this has been removed
8292 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8294 * Rewrote major parts of the ID cache system. Don't know
8295 whether it is better now or not but at least the API is more
8298 * Major rewrite on ID cache stuff on client because of the ID
8299 cache API changes. Added idlist.c to client.
8301 * Also major rewrite on ID cache stuff on server as well.
8302 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8303 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8304 in hand, instead they are all put into the ID cache system now.
8305 All server_idlist_* routines uses ID cache now instead of
8306 traversing its own lists (those lists does not exist anymore).
8307 SilcIDList though still exists. Also, SilcXXXEntry's are
8310 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8312 * Finally made the SKE implementation compliant to the protocol
8313 specification. All mp integers are now binary encoded as
8314 opposed being HEX encoded.
8316 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8319 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8320 functions: silc_[encode/decode]_pem. Also added function
8321 silc_encode_pem_file to PEM encode with newlines ('\n') for
8324 * SILC public keys are now encoded either PEM or binary. Same
8325 option is for private keys as well. By default private keys
8326 are binary encoded and public keys PEM encoded. Silly HEX
8327 encoding were removed.
8329 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8330 function to create fingerprints.
8332 * Fixed a bug in SHA1; does not change the original data anymore.
8334 * Partly implemented INFO command on client and server side.
8335 Fixed CLEAR command. Changes to SERVER command; show current
8336 server(s) when giving command without arguments. Added
8337 VERSION command to client.
8339 * Added check to server that unregistered connections cannot
8340 execute commands (unless it is specificly allowed).
8342 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8344 * Fixed screen refresh.
8346 * Fixed channel joining bug from client. On some circumstances
8347 client tried to join to a channel it had already joined.
8349 * Added public key verification process into client's protocol.c.
8350 The client now verifies the public key from user and saves
8351 it into ~./silc/serverkeys/ directory.
8353 Added into: clientutil.[ch]: silc_client_verify_server_key.
8355 * Changed SKE protocol's silc_ske_initiator_finish function
8356 to accept callback function that verifies the received public
8357 key. Removed old silc_ske_verify_public_key function.
8359 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8362 silc_pkcs_private_key[_data]_set.
8364 * Made the password and public authentication more cleaner in
8365 server's protocol.c.
8367 * Removed historic and obsolete protocol `channel_auth' from
8368 both client and server.
8370 * Removed wrong way of sending command status messages from
8371 server to client in server's command.c. The old way violated
8372 protocol specification.
8374 Changes to silccore/silccommand.[ch]: removed
8375 silc_command_encode_status_payload -> not needed anymore,
8376 changed silc_command_encode_payload_va to accept extra
8377 argument on variable argument list. The argument type must
8378 now be provided to the function. Also, added new function:
8379 silc_command_encode_reply_payload_va which is same as
8380 normal command_encode_payload_va except command status type
8381 is provided as extra argument.
8383 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8385 * Added ~./silc directory handling. The directory includes the
8386 public and private keys for the client.
8388 Added silc_client_check_silc_dir, silc_client_create_identifier
8389 and silc_client_load_keys.
8391 * Implemented SILC protocol compliant public key. Added public
8392 and private key saving to and loading from files.
8394 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8395 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8396 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8397 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8398 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8400 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8401 silc_pkcs_load_[public/private]_key.
8403 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8405 * Added silc_server_get_route (route.[ch]) to get connection
8406 data for the fastest route for given ID.
8408 * Implemented INVITE command on client and server. The command
8409 were re-defined in the SILC Protocol Specification and the
8410 implementation now complies with the specification.
8412 * Implemented PING command on client and server.
8414 * Implemented NAMES command on client and server. The server side
8415 supports currently only normal server not router server yet.
8416 Some changes to NAMES definition in SILC protocol specification.
8418 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Implemented LEAVE command on client and server.
8422 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8423 again. This change was made to the protocol as well. Server
8424 should not violate the protocol specification anymore.
8426 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8428 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8429 was tested. SOCKS4 was not but should work anyway.
