508 * Some client implementations quit network by doing first LEAVE
509 and then immediately SIGNOFF (like Bombyx). We now do check
510 after a short time after LEAVE notify and check whether the
511 client is still valid after LEAVE, and if not we remove it from
512 cache. Affected file is lib/silcclient/client_notify.c.
514 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
516 * Merged version 1.1.4 of zlib. Even if it not currently in use,
517 it's good not to have security holes here.
519 * Fixed a negative refcount situtuation for the config context.
520 Affected file is silcd/serverconfig.c.
522 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
524 * ROBOdoc documented lib/silcutil/silcutil.h.
526 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
528 * Optimized even more the SilcPacketContext structure. Now
529 totally saved 16 bytes of memory per context after optimization.
530 Affected files are lib/silccore/silcpacket.[ch].
532 * Made strict checks for valid SILC IDs. Affected file is
533 lib/silccore/silcid.c.
535 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Changed the object argument for silc_cipher_register,
538 silc_hash_register, silc_hmac_register and silc_pkcs_register
539 to const. Affected files are lib/silccrypt/silccipher.[ch],
540 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
542 * Changed the silc_get_username and silc_get_real_name to
543 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
545 * Fixed the Irssi SILC Client to use the silc_get_username and
546 silc_get_real_name insted of glib routines since the glib
547 routines only corrupt stack. Fixes the Irssi SILC to work in
548 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
550 * Fixed the Irssi to not use g_get_home_dir since it crashes
551 or returns garbage on cygwin and corrupts stack. Added function
552 get_home_dir to Irssi routines. Affected files are
553 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
555 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Made some structure optimizations. SFTP memory FS MemFSEntry
558 entry structure. Optimized SilcTask structure. Optimized
559 SilcPacketContext structure.
561 Affected files lib/silcsftp/sftp_fs_memory.c,
562 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
564 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
566 * And yet again reverted back the config thing since Johnny
567 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
570 * Fixed memory leaks from config object. Affected files are
571 silcd/serverconfig.[ch].
573 * Added support for adding new connections to the server in rehash.
574 After rehash they take effect.
576 Added support for changing the maximum allowed connections in
577 rehash. The number can grow but going smaller is not supported.
579 Added function silc_server_num_sockets_by_remote to the
580 silcd/server_util.[ch].
582 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
584 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
586 * Added preliminary checking during config parsing for a valid
587 public/private key and removed further checks in the code.
588 Affected files are silcd/serverconfig.[ch], server.c.
590 * Moved functions silc_server_drop() and silc_server_daemonise()
591 from server.c to silcd.c since they are stricly related to
592 the application activity.
594 * Reverted a small part of the automatic ref/unref since
595 it caused a double unref in some situations. Affected
596 files are silcd/silcd.[ch], server.c, serverconfig.c.
598 * Added some .cvsignore files in the lib directory.
600 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
602 * Fixed silc_net_gethostbyaddr to correctly resolve by
603 address. Affected file lib/silcutil/silcnet.c.
605 * Fixed the notify relaying to client. The HMAC to be used
606 with relayed packets ws wrong and caused decryption failure
607 at the client end. Affected file is silcd/packet_receive.c.
609 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
611 * Created new branch silc_protocol_1_0_branch.
613 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
615 * Changed the silc_server_config_* routines to be SilcServer
616 independent. They are now officially application specific code
617 and not part of generic server implementation. Affected files
618 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
620 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
622 * Added automatic referencing of config context in the
623 silc_server_config_alloc, and automatic unreferencing in the
624 silc_server_config_destroy. Affected files are
625 silcd/serverconfig.[ch], silcd/silcd.c.
627 * Fixed the silc_log_quick handling in the logging routines.
628 It didn't log quickly when it was TRUE. Affected file is
629 lib/silcutil/silclog.c. Also the flush delay was set even
630 if it was 0 in config file. Affected file is
631 silcd/serverconfig.c.
633 * Added support for changing key pair of the server in rehash.
634 Affected file silcd/server.c.
636 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
638 * Fixed the TOPIC_SET notify to not cras. It changed the topic
639 too early, before getting the channel entry. Affected file
640 is silcd/packet_receive.c.
642 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
644 * Added functions silc_server_config_[ref/unref], these are used
645 to prevent that the config object is destroyed.
647 No longer directly affect global variables silc_log_quick and
648 silc_log_delay, they are first cached inside the config object
649 and then applied with silc_server_config_setlogfiles().
651 silc_server_config_set_defaults() is now internal to
652 serverconfig.c, there are no reasons to show this internal stuff
655 Affected files are silcd/serverconfig.[ch].
657 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
658 fprintf's to stderr, since some code may be executed again after
659 the server went into the background. Affected files are
662 * Added rehash support. Added function silc_server_rehash() that
663 will perform all the basic tasks of the rehashing procedure.
665 * Added command line option `-x, --hexdump'. This will enable the
666 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
667 The option `--hexdump' implies `--debug'.
669 * Fixed a bad bug in the logging APIs (silcutil library) where
670 the application would crash after calling silc_log_reset_all().
672 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Fixed the KICKED notify handling in client library to
675 correctly remove the channel and all entries from the
676 channel when I was kicked. This bug crashed the client.
678 Fixed yet another but in KICKED notify handling to remove
679 the kicked client correctly from the channel.
681 Affected file is lib/silcclient/client_notify.c.
683 * Fixed a minor bug in looking up correct client entry
684 in KICKED notify in server. Affected file is
685 silcd/packet_receive.c.
687 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
688 sources correctly to distribution. Fixes --with-gmp option.
690 * Removed the manual rehashing from ID Cache, and changed it
691 to use the SILC Hash Table's auto rehash feature. Affected
692 file is lib/silccore/silcidcache.c.
694 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
696 * Fixed a bug in the silc_client_nickname_format function that
697 handles the multiple same nickname formatting. Two clients
698 with same nickname caused problems after the first one left
699 and rejoined. It didn't format the nickname correctly.
700 Affected file is lib/silcclient/idlist.c.
702 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
704 * Don't change the topic if olod topic is same as new one.
705 Affected file is silcd/packet_receive.c.
707 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
709 * Added cross-reference support to the SILC Documentation
710 generator. All types across all HTML files are now cross-
711 referenced. Affected files util/robodoc/generator.c and
712 scripts/silcdoc/silcdoc.
714 * Added file lib/silcutil/silctypes.h to include all the
715 arithmetic type definitions and some macros. Removed
716 includes/bitmove.h and moved macros to silctypes.h.
718 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
720 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
722 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Added `type' argument to silc_id_payload_parse_id function which
725 now returns the type of the ID to the sent pointer. Affected
726 file is lib/silccore/silcid.[ch].
728 * Added check for CMODE_CHANGE notify type that mode change is
729 allowed by the sender. Affected file silcd/packet_receive.c.
731 * Added check for CUMODE_CHANGE notify type that mode change is
732 allowed by the sender. Affected file silcd/packet_receive.c.
733 Added the ID type as CUMODE_CHANGE notify type as argument
734 to the `notify' client operation. Affected files are
735 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
737 * Added function silc_client_add_server to the client library.
738 Added support for resolving also channel and server info when
739 received unknown entity in notify packet. Affected files are
740 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
742 * Added function silc_command_get_status to return the command
743 status from the command reply's argument payload. Affected files
744 are lib/silccore/silccommand.[ch].
746 * Added check for KICKED notify type that the kicking is
747 allowed by the client. Affected file silcd/packet_receive.c.
749 * Created function silc_get_input which can be used to get input
750 (echo on or off) from user on command line. Affected files are
751 lib/silcutil/silcutil.[ch].
753 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
755 * Optimized silc_server_packet_relay_to_channel function.
756 Added new function silc_channel_message_payload_encrypt which
757 can be called directly if channel message payload needs to
758 be encrypted and is already encoded (no need to call _encode
759 function). Packet relaying is now done by router without any
760 extra memory allocations. Affected files are
761 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
764 * Fixed the INVITE notify handling. It took wrong arguments
765 as invite list and invite delete. Affected file is
766 silcd/packet_receive.c.
768 * Added check for TOPIC_SET notify type that the topic change is
769 allowed by the client. Affected file silcd/packet_receive.c.
771 * Added check for INVITE notify type that inviting is allowed by
772 the client. Affected file silcd/packet_receive.c.
774 * Changed the silc_server_client_on_channel to return the
775 SilcChannelClientEntry as well. Moved the function
776 silc_server_check_cmode_rights to server_util.[ch].
777 Affected files are silcd/server_util.[ch], silcd/command.c.
779 * Added function silc_server_check_umode_rights to check whether
780 changing client's user mode is allowed. Added check for
781 UMODE_CHANGE notify type that the umode change is allowed
782 by the client. Affected files are silcd/server_util.[ch],
783 silcd/packet_receive.c and silcd/command.c.
785 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
787 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
788 ID length. It ignored that ID can be IPv6 based as well.
789 Affected file lib/silccore/silcpacket.h.
791 * Fixed the silc_id_id2str and silc_id_str2id to take the
792 IPv6 address offset's into consideration. Affecte file is
793 lib/silccore/silcid.c.
795 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Fixed the internal Unix scheduler functions to check for
798 NULL context they may receive. The affected file is
799 lib/silcutil/unix/silcunixschedule.c.
801 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
803 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
804 can specify different directory with --home command line
805 parameter. Affected files irssi/src/silc/core/client_ops.c,
808 * SILC-specific commands aren't now executed if the active server
809 isn't of SILC-type, so there won't be problems with having
810 IRC and SILC protocol support in same client. Affected files
811 irssi/src/silc/core/silc-channels.c, silc-servers.c,
814 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Improved the signal support in SILC Schedule. Added new
817 function silc_schedule_signal_call which is used by application
818 to mark a signal to be called. It is now safe to perform
819 any kind of tasks in signal callbacks since it is guaranteed
820 that the application specified signal callback is called
821 after the signal is over. Affected files are
822 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
824 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
826 * Added `name' field to SilcChannelPrivateKey to represent
827 application given name for the key. Moved also the context from
828 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
829 Added the `name' argument also to the function
830 silc_client_add_channel_private_key.
832 Added function silc_client_current_channel_private_key to set the
833 current channel private key in use.
835 Added "change" command to KEY command which can be used to change
836 the current channel private key. Bound the command also to
839 Also affected files lib/silcclient/client_channel.c,
840 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
842 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
844 * Added silc_rng_get_byte_fast function in to the
845 lib/silccrypt/silcrng.[ch].
847 * Changed the interface of silc_packet_assemble and the
848 silc_packet_send_prepare. If silc_packet_assmble is now
849 called the application does not call silc_packet_send_prepare
850 because the library will call it automatically. These
851 interfaces now also return a reference to the outgoing buffer
852 which includes the assembled packet, which the application can
853 use to encrypt the packet.
855 Affected files are lib/silccore/silcpacket.[ch],
856 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
857 silcd/packet_send.c, server_backup.c and packet_receive.c.
859 * Fixed a packet sending bug on very high load, where outgoing
860 packet queue wasn't handled correctly and packets got corrupted.
861 Affected files are lib/silcutil/*/silc*sockconn.c,
862 lib/silcclient/client.c and silcd/server.c.
864 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
866 * Added macro SILC_PACKET_DATALEN which can be used during
867 packet assembling to check whether the data to be added to
868 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
869 len is truncated until it fits it.
871 Added checks for maximum length of channel message payload and
872 private message payload also.
874 Added checks for maximum packet length in server and in
877 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
878 lib/silcclient/client.c, lib/silccore/silcchannel.c and
879 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
880 lib/silcclient/client_prvmsg.c.
882 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
884 * Added silc_server_packet_queue_purge call to the
885 silc_server_disconnect_remote to assure that all data in the
886 queue before disconnecting is sent to the network. Affected
889 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Added the deleting of server's own ID cache entry to the
892 silc_server_free function. Free also everything else that
893 has been allocated in silc_server_init. The affected file
896 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
898 * Added functions silc_parse_version_string, silc_version_to_num,
899 and silc_ske_parse_version to parse SILC protocol style version
900 strings. Affected files lib/silcutil/silcutil.[ch] and
901 lib/silcske/silcske.[ch].
903 * Added new configuration params: version_protocol, version_software
904 and version_software_vendor to specify what version the remote
905 host must at least be to be able to connect to server. The vendor
906 string can be regex matched too. Added new function
907 silc_server_connection_allowed to check maximum number of allowed
908 connections, and allowed versions for incoming connections.
909 Affected files are silcd/server.c, server_util.[ch] and
912 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Added preliminary support for signals in scheduler. The
915 signals we care about are now blocked always when the scheduler
916 is locked. This way we can synchronise the use of signal with
917 scheduler. It is guaranteed that when signal occurs the scheduler
918 is not locked, and thus new tasks can be safely added to the
921 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
922 to silc_schedule_internal_init and silc_schedule_internal_uninit.
923 Added new platform specific routines
924 silc_schedule_internal_signals_[un]block and
925 silc_schedule_internal_signal_[un]register.
927 Added new functions to SILC Schedule API:
928 silc_schedule_signal_[un]register. Each signal that application
929 is going to use should be registered to the scheduler.
931 Affected files are lib/silcutil/silcschedule.[ch],
932 lib/silcutil/*/silc*schedule.c.
934 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
936 * Check for unauthenticated client and server in the
937 silc_server_new_client and silc_server_new_server functions.
938 Affected file silcd/packet_receive.c.
940 * Added function silc_string_is_ascii to check whether given
941 string is 7-bit ASCII string. Affected files are
942 lib/silcutil/silcutil.[ch].
944 * Added function silc_id_is_valid_server_id into the
945 silcd/serverid.c and added checking for valid Server ID's in
946 silc_server_new_server. The Server ID must always be based
947 on the server's public IP address.
949 * Added logging of DISCONNECT packet message in the server.
950 Affected file silcd/server.c.
952 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
954 * Changed all library interfaces that use Global RNG to also
955 accept SilcRng as argument. Affected files are
956 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
957 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
958 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
959 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
962 * Added function silc_pkcs_generate_key to the
963 lib/silccrypt/silcpkcs.[ch] for applications so that they
964 don't need to do pkcs->pkcs->init calls anymore.
966 * Remove SilcSocketConnection from the SFTP API since it really
967 wasn't needed there. The application has the information
968 saved in its contexts anyway and the SFTP layer doesn't need
969 know about it. Affected files lib/silcsft/silcsftp.h and
970 lib/silcsftp/sftp_[server/client].c.
972 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
973 The SilcSimContext is not SilcSim.
975 * Fixed possible buffer overflows in silc_id_render in the
976 lib/silcutil/silcutil.c.
978 * On EPOC the global crypto module lists are not used at all
979 in the crypto library. Added support for using the constant
980 algorithm list on EPOC. Affected files are
981 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
984 * Fixed the handling of third parameter of KICKED notify, since
985 it was mistakenly updated to SILC Protocol 1.0 even though it
986 is to be included in 1.1. Since it is not in 1.0 it is not
987 mandatory, and this fix now handles it only if it is provided,
988 and it is not error if it is not provided. Affected file
989 lib/silcclient/client_notify.c.
991 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
994 client. Affected file irssi/src/silc/core/client_ops.c.
996 * Merged with Irssi 0.8.4 from irssi.org CVS.
998 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1000 * Check for valid socket connection in client entries before
1001 sending any messages. Fixes a crash, but doesn't fix some
1002 other underlaying bug that is lurking there. Affected
1003 file silcd/packet_send.c.
1005 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1007 * $usermode, $cumode and $cumode_space expandos shouldn't do
1008 anything with non-SILC server records. Affected file
1009 irssi/src/silc/core/silc-expandos.c
1011 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1013 * Fixed the silc_net_check_[host/local]_by_sock to support
1014 IPv6 bound sockets as well. Now they can return IPv6 addresses
1015 as well. Affected file lib/silcutil/silcnet.c.
1017 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1018 Affected lib/silcutil/unix/silcunixnet.c.
1020 * Fixed ID rendering (at least on some platforms, not NetBSD)
1021 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.

1025 * Added silc_hash_public_key and silc_hash_public_key_compare
1026 functions to be used with SilcHashTable. They can be used to
1027 hash public keys and compare public keys in hash table. Affected
1028 file lib/silcutil/silcutil.[ch].
1030 * Added support for specifying multiple public keys for Client
1031 connection section in server configuration file. This makes it
1032 possible to accept multiple public keys from same host, or to
1033 make a section that accepts any incoming host, and have the
1034 accepted public keys listed in the section.
1036 Added functions silc_sever_[find/get]_public_key, added the
1037 support for this actually to all connection sections but only
1038 the Client section is currently allowed to specify multiple

1145 application does not need to define them. Affected file
1146 includes/silcincludes.h.
1148 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1149 old name went against naming convention. Applications now
1150 include "silcclient.h" instead of "clientlibincludes.h".
1151 Removed includes/clientlibincludes.h, it is redundant now.
1153 * Renamed includes/version.h to silcversion.h.
1155 * Added really preliminary support for OS/2 into the util
1156 library. Only thread & mutex API is implemented, others
1157 are still to be implemented. Created the lib/silcutil/os2/

1191 * Added `user_count' to the SilcChannelEntry which now tells the
1192 number of users on the channel. The user count is now saved
1193 in normal server of global channels as well. Affected files
1194 silcd/server.c, idlist.h, packet_receive.c and command.c.
1196 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1197 include file utility functions.
1199 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1200 instead of calling directly OS routines.

1212 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1213 the SKE interface a bit.
1215 * Fixed padding problem in PKCS#1. The padding was not actually
1216 random since the random number generator was used incorrectly.
1217 This security bug affects only when encrypting with PKCS#1, and
1218 it is not currently used at all in SILC. SILC only use signing
1219 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1279 is now done in silc_core_init() which also fixes autoconnecting
1282 Affected files irssi/src/silc/core/silc-core.c,
1283 irssi/src/fe-text/silc.c.
1285 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1287 * Added new configuration options and blocks:
1288 keepalive_secs, reconnect_count, reconnect_interval,
1289 reconnect_interval_max, reconnect_keep_trying and
1290 require_reverser_lookup. Added ConnectionParam block, and
1291 implemented the connection parameters when connecting as
1292 initiator and when accepting connections as responder.

1304 the connection configuration object from the SilcServerConnection
1305 object instead of finding it during the connecting phase.
1306 Added the configuration object to SilcServerConnection struct.
1307 Affected files silcd/server_internal.h, server.c.
1309 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1311 * Add the client on channel after it was resolved at the
1312 channel message receiving, and it was not already on the
1313 channel. Affected file lib/silcclient/client_channel.c.
1315 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1331 authentication to be set at the same time.
1333 Added `prefer_passphrase_auth' setting in config file which
1334 can be used to set to prefer passwd auth if both passwd and
1335 public key is set. If not set, public key is preferred.
1336 This has effect only when being initiator (responder will try
1339 Added support for authentication with passphrase and public key
1340 at the same time. The passphrase is tried first always since
1341 it is faster to check.
1343 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1345 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1391 * Fixed the file transfer's key agreement payload to include
1392 zero port also if the hostname is NULL because it could not
1395 Call file transfer monitor callback now also if error occurs
1396 during key agreement protocol.
1398 Changed the silc_client_file_send interface to return the
1399 SilcClientFileError instead of session id. The session ID
1400 is returned into pointer provided as argument.

1413 irssi/src/silc/core/silc-channels.c.
1415 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1416 SILC_LOG_WARNING to give out Warning and not Error. Affected
1417 file lib/silcutil/silclog.c.
1419 * Fixed the channel message payload decryption in the function
1420 silc_channel_message_payload_decrypt to not modify the original
1421 buffer before it is verified that the message decrypted
1422 correctly. Otherwise, next time it is called with correct
1423 channel key it won't encrypt since the payload is corrupted.
1424 Affected file lib/silccore/silcchannel.c.
1426 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1438 * Fixed a bug in hash table internal routine for traversing
1439 the table with foreach callback. The current entry may
1440 become invalid in the callback but it was referenced after
1441 the callback returned.
1443 Do not allow auto rehashing of hash table during the
1444 silc_hash_table_foreach operation, for same reasons as it is
1445 not allowed for SilcHashTableList. Affected files are
1446 lib/silcutil/silchashtable.[ch].
1448 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1458 lib/silcclient/client_prvmsg.c.
1460 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1462 * Added function silc_client_add_channel,
1463 silc_client_replace_channel_id, and removed functions
1464 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1465 from client library.
1467 * Added cross reference of the joined channels to the
1468 SilcClientEntry, and changed the SilcChannelEntry's
1469 users list to SilcHashTable. The affected files are
1470 lib/silcclient/idlist.[ch].
1472 * Fixed a bug in hash table tarversing. While the hash table
1473 is traversed with SilcHashTableList the table must not be
1474 rehashed. It is now guaranteed that auto rehashable tables
1475 are not rehashed while tarversing the list. Also defined that
1476 silc_hash_table_rehash must not be called while tarversing
1477 the table. Added function silc_hash_table_list_reset that must
1478 be called after the tarversing is over. The affected files are
1479 lib/silcutil/silchashtable.[ch].
1481 * Changed all hash table traversing to call the new
1482 silc_hash_table_list_reset in server and in client library.
1484 * Added function silc_client_on_channel to return the
1485 SilcChannelUser entry if the specified client entry is joined
1486 on the specified channel. This is exported to application as
1487 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1489 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1492 server. The notify for mode change must be sent always and
1493 not only if !cmd->pending. Affected file silcd/command.c.
1495 * Fixed the WHOWAS command's reply sending to support the
1496 lists correctly. Affected file silcd/command.c.
1498 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1500 * When sending JOIN command to router for processing the
1501 sender's old command identifier was not saved back to the
1502 sender's command context, fixed now. The affected file is
1505 * Create the key in JOIN command of the router did not return
1506 the channel key, added check for this. Affected file is
1509 * Fixed a channel ID update bug in JOIN command reply. Do
1510 not directly upgrade the ID but call the function
1511 silc_idlist_replace_channel_id if the ID was changed.
1512 Affected file silcd/command_reply.c.
1514 * Fixed memory leaks from command calling if it would fail.
1515 Affected file silcd/command.c.

1527 * Removed TRQ from lib/trq, not needed anymore.
1529 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1530 with server connections. Later this will be configurable
1531 in config file after new config file is done. Affected file
1534 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1536 * Fixed a crash in server related to channel announcements.
1537 Affected file silcd/server.c.
1539 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1541 * Fixed memory leaks in silc_server_create_new_channel*
1542 functions. Affected file silcd/server.c.
1544 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1545 which ID was changed. This way the router will send the
1546 user list for the channel again, and server won't be in
1547 desync in some rare circumstances. Affected file is
1548 silcd/packet_receive.c.
1550 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1552 * Check for NULL socket pointer in the function
1553 silc_server_packet_send_to_channel_real. Affected file
1554 silcd/packet_send.c.
1556 * Fixed the BAN notify handling to correctly remove ban
1557 list. Affected file silcd/packet_receive.c.
1559 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1561 * Fixed some header addition to Toolkit distribution in
1562 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1564 * Added lib/silcclient/client_ops_example.h as an template
1565 file for application programmers to quickly start using
1566 the SilcClientOperation functions in their application.
1567 Updated the lib/silcclient/README as well to tell about this
1568 nice file made available.
1570 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1572 * Call silc_server_remove_from_channels when removing client
1573 entry when NO_SUCH_CLIENT_ID was received. Affected file
1574 is silcd/command_reply.c.
1576 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1578 * Added server & router operator statistics updating. Affected
1579 file silcd/packet_receive.c and silcd/command.c.
1581 * Fixed the SERVER_SIGNOFF notify handling on normal server
1582 not to save the history information for clients. Same was
1583 fixed earlier in remove_clients_by_server function, but not
1584 here. Affected file silcd/packet_receive.c.
1586 * Raised the default connection-retry count from 4 to 7 in
1587 server. Affected file silcd/server.h.
1589 * Cancel any possible reconnect timeouts when we start the
1590 key exchange. Affected file silcd/server.c.
1592 * Do not reconnect on connection failure when SCONNECT was
1593 given. Affected files silcd/server.[ch].
1595 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1597 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1599 * Fixed the NICK command to always give the unformatted
1600 nickname to the one giving the NICK command. If unformatted
1601 nickname is cached already it will be formatted and the
1602 local entry will always get the unformatted nickname.
1603 Affected file lib/silcclient/idlist.c.
1605 * Fixed some double frees from client library commands.
1606 Affected file is lib/silcclient/command.c.
1608 * Fixed CUMODE command in server to assure that no one can
1609 change founder's mode than the founder itself, there was a
1610 little bug. Affected file silcd/command.c.
1612 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1614 * Removed the SilcClientCommandDestructor from the client
1615 libary, it is not needed anymore. Affected files are
1616 lib/silcclient/silcapi.h, command[_reply].[ch],
1617 client_notify, idlist.c.
1619 * Fixed GETKEY command to first resolve client, and then
1620 resolve the server only if the client was not found, instead
1621 of resolving both at the same time. Affected file is
1622 lib/silcclient/command.c.
1624 * Added silc_client_start_key_exchange_cb and lookup the
1625 remote hostname and IP address before starting the key
1626 exchange with server. The affected file is
1627 lib/silcclient/client.c.
1629 * The server's public key is now saved using the IP address
1630 of the server and not the servername for the filename.
1631 The hostname public key filename is checked as an fall back
1632 method if the IP address based filename is not found.
1634 Fixed the GETKEY command to save the fetched server key
1635 in correct filename.
1637 Print the remote server's hostname now when new key is
1638 received during connection process. Affected file is
1639 irssi/src/silc/core/client_ops.c.
1641 * Return always our own public key to the client if it asks
1642 for it with GETKEY command. Affected file silcd/command.c.
1644 * Removed the use_auto_addr variable from default config
1645 file since it was in wrong section. Affected file is
1648 * Fixed TOPIC_CHANGE notification to not route it when it
1649 was sent using silc_server_send_notify_to_channel function.
1650 Affected file silcd/command.c.
1652 * Fixed silc_server_send_notify_kicked to send the kicker's
1653 Client ID also, it was missing. Affected files are
1654 silcd/command.c, silcd/packet_send.[ch].
1656 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1658 * Do not save client history information in SERVER_SIGNOFF.
1659 Fixes the bug in normal server that it does not detect
1660 the client becoming valid after the server becomes back
1661 online. Affected file silcd/server_util.c.
1663 * Added `sock_error' field into the SilcSocketConnection
1664 context. When error occurs during socket operation (read
1665 or write) the error is saved. Added also new function
1666 silc_socket_get_error to return human readable socket error
1667 message. Affected files are lib/silcutil/silcsockconn.[ch],
1668 lib/silcutil/unix/silcunixsockconn.c, and
1669 lib/silcutil/win32/silcwin32sockconn.c.
1671 * The server now prints the socket error message in the
1672 signoff for client. Affected file silcd/server.c.
1674 * Fixed the `created' channel information sending from router
1675 to server in JOIN command. Checks now whether the channel
1676 really was created or not and set it according that.
1678 Fixed the JOIN command to use the client entry's current
1679 ID during the joining procedure instead of the one it sent
1680 in the command (it is checked though), since it can change
1681 between the packet processing and command processing, and
1682 would just case unnecessary pain in the client end. Affected
1683 file silcd/command.c.
1685 * Fixed a channel key payload sending to use correct channel
1686 ID when the server was forced to change the channel's ID by
1687 router. Router sent the key payload with the old Channel ID.
1688 Affected file silcd/packet_receive.c.
1690 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1692 * Call silc_server_save_channel_key only if the key payload
1693 was provided in the JOIN command's command reply. Affected
1694 file silcd/command_reply.c.
1696 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1698 * Fixed silc_mp_sizeinbase to return the value correctly with
1699 MPI. Affected file lib/silcmath/mp_mpi.c.
1701 * Fixed the stop_server signal to correctly stop the scheduler
1702 and gracefully stop the server when SIGTERM or SIGINT signals
1703 are received. Affected file silcd/silcd.c.
1705 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1707 * Simple handling of TERM and HUP signals. Also added some log
1708 flushing call around. Affected file is
1711 * Fixed small bugs in silclog.c. Now buffering output will take
1712 effect after 10 seconds since startup: This will ensure that
1713 no important startup messages are lost. Also output redirection
1714 will preserve original format ([Date] [Type] message).
1715 Affected file is lib/silcutil/silclog.c.
1717 * Added two options to the config file, in the logging section:
1718 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1719 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1721 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1723 * Do not print the warning about log files not being initialized
1724 more than once to avoid excess logging. Affected file is
1725 lib/silcutil/silclog.c.
1727 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1728 the SIM copying in make install in Makefile.am.pre.
1730 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1732 * Rewritten silclog APIs. Globally interesting changes follows:
1733 silc_log_set_files() changed to silc_log_set_file().
1734 silc_log_set_callbacks() changed to silc_log_set_callback().
1735 ROBOdoc documented silclog header file.
1736 SilcLogCb now returns bool to wether inihibit the default
1737 handler or not (to keep the old behaviour return always TRUE).
1738 The new APIs should also fix the problem of the
1739 silcd_error.log file that was written in the current directory.
1742 Log files streams will remain opened after silc_log_set_file()
1743 call, means less CPU usage notably on high traffic servers.
1744 File streams are now full buffered, and flushed to the disk
1745 every 5 minutes, lesses HD activity and CPU usage.
1746 Messages can be redirected, allowing admins to configure
1747 one single logfile for all server messages.
1748 the silc_log_quick global variable to activate fast-logging.
1749 Affected files lib/silcutil/silclog.[ch]
1751 * Changed some code to conform new silclog APIs. Affected
1752 files are doc/example_silcd.conf.in, silcd/server.c
1753 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1756 * Fixed a memory leak that could occur in some situations.
1757 Affected file silcd/serverconfig.c.
1759 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1761 * Added the silc_client_del_client to remove the client from
1762 all channels as well. Affected file lib/silcclient/idlist.c.
1764 * Fixed the client library to correctly remove the client
1765 from all channels when the client entry is being destroyed.
1766 Affected file lib/silcclient/client_notify.c, command.c.
1768 * Added auto-nicking support to the client library. If the
1769 applicatio now sets client->nickname it will be sent to the
1770 server after connecting by the library. This way for example
1771 SILCNICK (or IRCNICK) environment variables will have effect
1772 and always change the nickname automatically to whatever
1773 it is wanted. Affected file lib/silcclient/client.[ch].
1775 * Renamed silc_server_command_bad_chars to the
1776 silc_server_name_bad_chars and moved it to the
1777 silcd/server_util.[ch]. Added also new function
1778 silc_server_name_modify_bad to return nickname that
1779 includes bad characters as new nickname without those
1780 bad characters. This check and modify is now used in
1781 silc_server_new_client when the username is initially set
1782 as nickname, so it must be checked to be valid nickname.
1783 Affected file silcd/packet_receive.c.
1785 * The nickname length is now taken from the packet for real
1786 and not trusted to strlen() since it clearly can return
1787 wrong length for nickname including bad characters. This
1788 also applies to channel names. Affected file silcd/command.c.
1790 * Removed the lib/silcsilm/modules directory. Modules are now
1791 compiled into the lib/silcsim. Fixed the copying of the
1792 modules to follow symbolic links in Makefile.am.pre.
1794 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1796 * Fixed silc_string_regexify list creation. Fixes bugs with
1797 BAN and INVITE commands in server. The affected file is
1798 lib/silcutil/unix/silcunixutil.c.
1800 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1802 * Removed the command destructor entirely from the server's
1803 command and command reply routines. It is not needed, and
1804 its usage was buggy and caused crashes. Affected files are
1805 silcd/command[_reply].[ch].
1807 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1809 * Cancel protocol and NULL sock->protocol if timeout
1810 occurred during protocol. Affected file silcd/server.c.
1812 * Cancel protocol timeouts always before calling the final
1813 callback, to assure that after final callback is called
1814 no other state will be called for the protocol anymore.
1815 Affected file silcd/protocol.c.
1817 * Print error log if incoming connection configuration could
1818 not be found. Affected file silcd/server.c.
1820 * Fixed JOIN command to correctly save the founder mode
1821 to the client on normal SILC server, when the channel
1822 was created by the router. Affected file silcd/command.c.
1824 * Fixed LIST command (hopefully) to send correct reply
1825 packets. Affected file silcd/command.c.
1827 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * The silc_packet_receive_process now returns FALSE if the
1830 read data was invalid packet, and TRUE if it was ok.
1832 The server now checks that if unauthenticated connection
1833 sends data and its processing fails the server will close
1834 the connection since it could be a malicious flooder.
1836 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1838 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1840 * Make sure the warning about error opening a log file is
1841 printed only once and not everytime it fails (produces
1842 too much useless log). Affected file lib/silcutil/silclog.c.
1844 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1846 * Made the silc_server_daemonise() function more readable.
1847 Affected file silcd/server.c.
1849 * Pid file is now optional, the user may comment it out from
1850 the config file. Removed define SILC_SERVER_PID_FILE, we
1851 don't need a default any longer. Affected file
1852 configure.in.pre, lib/Makefile.am.pre.
1854 * Make some use of the pid file. The server now dies at startup
1855 if it detects a valid pid file on his path. The server would
1856 die anyway in this circumstance, because of the bind() failure.
1857 Affected file silcd/silcd.c.
1859 * No longer compiling lib/dotconf.
1861 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Fixed JOIN command parsing not to crash. Affected file
1864 lib/silcclient/command.c.
1866 * Fied the NICK_CHANGE notify to add the new client entry
1867 even it is resolved. This removes an <[unknown]> nick
1868 thingy bug in the client. Affected file is
1869 lib/silcclient/client_notify.c.
1871 * Do not try to allocate 0 bytes (efence does not like it)
1872 in lib/silccore/silccomand.c when encoding payload.
1874 * Do not take IRCNICK as nickname in Irssi SILC client since
1875 it is not possible to set nickname before hand connecting
1876 the server (TODO has an entry about adding auto-nicking
1879 * Changed the silc_server_command_pending to check whether
1880 there already exists an pending entry with the specified
1881 command, command identifier and pending callback. This is
1882 to fix IDENTIFY and WHOIS related crashes that may register
1883 multiple pending commands with same identifier. Affected
1884 file silcd/command.c.
1886 * Fixed the server to reconnect to the router even if it
1887 was already reconnecting and EOF was received. This to
1888 fix a possibility that the server wouldn't ever try to
1889 auto-reconnect to the router. Affected file silcd/server.c.
1891 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Fixed the server's password authentication to use the
1894 length of the locally saved password, and not the one
1895 sent in the packet. Affected file silcd/protocol.c.
1897 * Fixed same password authentication problem in the
1898 Authentication Payload handling routines in
1899 lib/silccore/silcauth.c.
1901 * Yet another password authentication problem fixed with
1902 channel password handling in silcd/command.c.
1904 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * If first character of string in silc_parse_userfqdn is '@'
1907 then do not parse it. Affected file is
1908 lib/silcutil/silcutil.c.
1910 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Fixed minor bug in IDENTIFY command reply sending, which
1913 caused various weird problems during JOIN when it was
1914 resolving names for users. Affected file silcd/command.c.
1916 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Fixed the IDENTIFY command reply sending to chech better valid
1919 clients. It was possible to send incomplete list of replies.
1920 Affected file silcd/command.c.
1922 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Added silc_client_command[s]_[un]register functions now to
1925 dynamically register the commands in client library. Removed
1926 the static table of commands. This allows the client library
1927 to call commands without causing the application to know about
1928 what commands library has called.
1930 Removed the INFO command reply kludge to detect when the command
1931 was called by library. Now library use its own command reply
1932 function for INFO command.
1934 Added function silc_client_command_call to call a command.
1935 Application can use it to call command, not access the structure
1938 Now all commands that are sent by the client library (not
1939 explicitly sent by application) use own command reply functions.
1941 Affected files around lib/silcclient/ and in
1942 irssi/src/silc/core/.
1944 * Fixed the WHOIS command reply sending to chech better valid
1945 clients. It was possible to send incomplete list of replies.
1947 Fixed the WHOIS and IDENTIFY to send the request to router
1948 if normal server did not do it and did not find any results.
1950 Affected file silcd/command.c.
1952 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1954 * Moved the internal data from SilcClient context into its
1955 own file, not accesible to application. Affected files
1956 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1957 and other files in client library.
1959 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Added doc/examples installation target in Makefile.am.pre.
1964 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1966 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1967 commands the found client entry will be removed from the
1968 cache, after notifying application about the error. Affected
1969 file lib/silcclient/command_reply.c.
1971 * Changed the /MSG to check for exact nickname user gave, and
1972 not let `nick' match `nick@host' if it is only one found. Now,
1973 user must type the exact nickname (like nick@host2) even if
1974 there are no more than one same nicks found. This is to avoid
1975 a possibility of sending nickname to wrong nickname since
1976 `nick' could match `nick@host'. Affected file is
1977 irssi/src/core/silc-servers.c.
1979 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1981 * Do not print "you are now server operator" or similar when
1982 giving /away command. Affected files are
1983 irssi/src/silc/core/client_ops.c, silc-servers.h.
1985 * Made the silc_server_command_pending_error_check to send
1986 the same command reply payload it received back to the
1987 original sender of the command. This way all arguments
1988 that was received by the server will be received by the
1989 client too. Affected file silcd/command.c.
1991 * Added the silc_idcache_add to return the created cache entry
1992 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1994 * Add global clients to expire if they are not on any channel.
1995 This is because normal server will never know if they signoff
1996 if they are not on any channel. The cache expiry will take
1997 case of these entries. This is done by normal servers only.
1998 The affected files are silcd/command_reply.c,
1999 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2001 * If server receives invalid ID notification for WHOIS or
2002 IDENTIFY and the ID exists in the lists, it is removed.
2003 Affected file silcd/command_reply.c.
2005 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2006 in client then client entry that it matches is searched and
2007 the nickname is printed on the screen for user. Affected
2008 file irssi/src/silc/core/client_ops.c.
2010 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2012 * Use cache entry expire time in the LIST command reply to
2013 purge old entries from the cache after the LIST command
2014 reply has been received. This way we don't have non-existent
2015 entries in the cache for too long. Affected file is
2016 silcd/command_reply.c.
2018 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2020 * If we are normal server, and we've not resolved client info
2021 in WHOIS or IDENTIFY from router, and it is global client,
2022 we'll check whether it is on some channel. If it is not
2023 then we cannot be sure about its validity and will resolve it
2024 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2025 file silcd/command.c.
2027 * Search channel by name (if possible) rather than by ID
2028 in IDENTIFY command's command reply. Affected file is
2029 silcd/command_reply.c.
2031 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2034 Updated specs and implemented it. Affected file silcd/command.c,
2035 silcd/packet_send.c and silcd/packet_receive.c.
2037 * Implemented the <founder auth> payload handling in the JOIN
2038 command. If provided all conditions for channel joining
2039 except requirement to provide correct passphrase can be
2040 overrided by the channel founder. Updated the protocol specs.
2041 Affected file silcd/command.c.
2043 Added support for founder auth in JOIN command in client
2044 library. Fixed the parsing of the JOIN command now to support
2045 all options as they should be. The affected file is
2046 lib/silcclient/command.c.
2048 * Optimized the WHOIS and IDENTIFY commands to send the request
2049 to router only if it includes nicknames or other names. If
2050 they include only IDs then check the local cache first before
2051 routing. Affected file is silcd/command.c.
2053 * Added channels topic announcements. Affected file is
2054 silcd/packet_receive.c and silcd/server.c.
2056 * Fixed the silc_server_send_notify_topic_set to really destine
2057 the packet to channel. Affected file silcd/packet_send.c.
2059 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2060 library. Affected file lib/silcclient/client_notify.c.
2062 * Added UMODE announcements. Affected file silcd/server.c.
2064 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Memory leak fixes in:
2068 lib/silcutil/silcsockconn.c
2069 lib/silcske/silcske.c
2070 lib/silcske/groups.c
2072 lib/silccrypt/silcpkcs.c
2073 lib/silccore/silccommand.c
2074 lib/silccore/silcidcache.c
2079 * ROBOdoc documented the lib/silcske/groups.h file and a
2080 bit changed the interface for better.
2082 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2084 * Update the client entry context in the ID cache after
2085 nick change. Affected file lib/silcclient/command.c.
2086 Fixes the CUMODE command when regaining founder privileges,
2087 and a little WHOIS problem.
2089 * Fixed silc_net_gethostbyname to correctly call the
2090 inet_ntop. Affected file lib/silcutil/silcnet.c.
2092 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2094 * Added IPv6 support checking to the configure.in.pre, added
2095 also --enable-ipv6 option to override the check. Affected
2096 file configure.in.pre.
2098 * The silc_thread_create now calls the start function
2099 directly if threads support is not compiled in. Removes
2100 ugly #ifdef's from generic code. Affected files are
2101 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2103 * Added silc_net_gethostby[name/addr]_async to asynchronously
2104 resolve. Affected files are lib/silcutil/silcnet.[ch].

2115 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2116 routines. Added silc_net_is_ip[4/6]. Affected file is
2117 lib/silcutil/unix/silcunixnet.c. All routines that take
2118 address as argument now supports both IPv4 and IPv6 addresses.
2120 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2122 * Fixed LIST command reply sending in server. Affected file
2125 * Server now sends the kicker's client ID in the KICK notify
2126 to the kicked client. Affected file silcd/command.c.
2128 * The client library now parses the kickers client ID and
2129 UI displays it. Affected files lib/silcclient/client_notify.c
2130 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2132 * Made all payload parsing function prototypes consistent.
2133 They all take now const unsigned char * and uint32 pair as
2134 the payload data instead of SilcBuffer. Changes all around
2135 the source tree. Other unsigned char* -> const unsigned char*
2136 changes around the tree as well.
2138 * Optimized SFTP client and server packet sending not to
2139 allocate new buffer for each packet but to recycle the
2140 first allocated buffer. Affected files are
2141 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2143 * Optimized the SFTP client to use SilcList instead of
2144 SilcDList for requests, because it is faster. Affected file
2145 is lib/silcsftp/sftp_client.c.
2147 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2148 into lib/silccore/silcid.[ch].
2150 Renamed silcpayload.[ch] into silcargument.[ch].
2152 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * If client entry is deleted with active key agreement
2155 session, abort the session.
2157 The silc_client_abort_key_agreement now calls the completion
2158 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2160 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2163 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * Don't use __restrict in older GCC's. Affected file is
2166 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2168 * silc_net_localhost now attempts to reverse lookup the
2169 IP/hostname. Affected file lib/silcutil/silcnet.c.
2171 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2172 command. It can be used to gain founder privileges at
2173 the same time when joining the channel.
2175 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2176 kicker's client ID as well. Updated protocol specs.
2178 Defined that the server must send SILC_COMMAND_IDENTIFY
2179 command reply with error status to client who sent
2180 private message with invalid client ID.
2182 Updated the protocol specification.
2184 * Added silc_server_send_command_reply to send any
2185 command reply. Affected file silcd/packet_send.[ch].
2187 * Added silc_id_payload_encode_data to encode ID payload
2188 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2190 * The server now send IDENTIFY command reply with error
2191 status if client ID in private message is invalid. Affected
2192 file silcd/packet_receive.c.
2194 * Save the server key file with server's IP address in
2195 the filename instead of hostname. The affected file is
2196 irssi/src/silc/core/client_ops.c.
2198 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2203 * Added libtool support for compiling shared objects in
2204 lib/silcsim. Affected file configure.in.pre and
2205 lib/silcsim/Makefile.am. Original patch by cras.
2207 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Pid file configuration, and server's config file fixes
2210 patch by toma. Updated CREDITS file.
2212 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2214 * Fixed silc_client_channel_message to not try to decrypt
2215 the message twice if it resolved the destination client
2216 information. This could cause of dropping one channel
2217 message. Affected file lib/silcclient/client_channel.c.
2219 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2222 lib/silcclient/client.c. This function is used when the SILC
2223 Client is run under some other scheduler, or event loop or
2224 main loop. On GUI applications, for example this may be
2225 desired to used to run the client under the GUI application's
2226 main loop. Typically the GUI application would register an
2227 idle task that calls this function multiple times in a second
2228 to quickly process the SILC specific data.
2230 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2232 * Fixed silc_server_drop() for dropping the supplementary
2233 groups as well, this could cause a security hole on some
2236 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2238 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2241 * Write PID file after dropping privileges. Added -F option
2242 to run server on foreground. A patch by debolaz.
2243 Affected files silcd/server.c, silcd/silcd.c.
2245 * Fixed MOTD to return the MOTD file server name. Affected
2246 file silcd/command.c.
2248 * Added INFO command reply handling to the Irssi SILC Client.
2249 Affected file irssi/src/silc/core/client_ops.c.
2251 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Fixed the silc_idcache_list_* routines to really support
2254 the dynamic list. Fixes a crash. Affected file is
2255 lib/silccore/silcidcache.c.
2257 * Fixed the LIST command reply to really call LIST command's
2258 pending callbacks. Affected file silcd/command_reply.c.
2260 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Update conn->local_entry->nickname after giving NICK
2263 command. Affected file lib/silcclient/command.c.
2265 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2267 * Added the [pid] option to the silcd configuration file
2269 Affected files: serverconfig.[ch] and silcd.c
2271 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Save fingerprint in WHOIS command reply in server.
2274 Affected file silcd/command_reply.c.
2276 * Fixed NICK commands pending callback registration.
2277 Affected file lib/silcclient/command.c.
2279 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2281 * Use ++server->cmd_ident when sending commands in server,
2282 instead of random number. Affected file silcd/command.c.
2284 * Fixed GETKEY command reply to call actually GETKEY pending
2285 command callbacks. Affected file silcd/command_reply.c.
2287 * A bit stricter check for nicknames. Check for same nickname
2288 in NICK command also. Affected file silcd/command.c.
2290 * Do not call INFO command everytime client ID changes, only
2291 during first connecting. Affected file lib/silcclient/client.c.
2293 * Set the new nickname only after successful command reply for
2294 NICK command is returned by server. Affected file
2295 lib/silcclient/command.c.
2297 * Remove nicknames from nicklist during server_signoff notify.
2298 Should fix /NAMES bit more. The affected file is
2299 irssi/src/silc/core/silc-channels.c.
2301 * Added `fingerprint' field to the SilcIDListData in the
2302 silcd/idlist.h to hold the fingerprint of the client's
2305 Send the fingerprint of the client's public key in WHOIS
2308 Affected files silcd/command.c, and silcd/idlist.[ch].
2310 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2311 create fingerprint from given data.
2313 * Show the fingerprint of the client's public key in WHOIS.
2314 Affected files irssi/src/module-formats.[ch] and
2315 irssi/src/silc/core/client_ops.c.
2317 * Format the multiple same nicknames also during JOIN and
2318 NICK_CHANGE notifys. Affected file is
2319 lib/silcclient/client_notify.c.
2321 * Do not print error on screen for invalid private message
2322 payload since it can come if someone is sending private
2323 messages with wrong key. Affected file
2324 lib/silccore/silcprivate.c.
2326 * Fixed multiple concurrent /PING crash. Affected file
2327 lib/silcclient/command.c.
2329 * Changed the wrong ID encoding. All IP addresses must be
2330 in MSB first order in encoded format. They were encoded
2331 wrong and was in LSB format. Affected files are
2332 silcd/serverid.c, lib/silcutil/silcutil.c.
2334 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2336 * Call the `connect' client operation through the scheduler
2337 in case of error. Affected file lib/silcclient/client.c.
2339 * Call the `failure' client operation even if the error
2340 occurred locally during a protocol. Affected file is
2341 lib/silcclient/protocol.c.
2343 * Added support of sending LIST command to router from normal
2344 server. This way normal server can get list of all channels
2345 in the network too. Fixed the channel list sending in the
2346 server too. Affected files are silcd/command.c, and
2347 silcd/command_reply.[ch].
2349 * Added silc_server_update_channels_by_server and
2350 silc_server_remove_channels_by_server. They are used during
2351 disconnection of primary router and in backup router protocol.
2352 Affected file silcd/server_util.[ch], silcd/server.c and
2353 silcd/server_backup.c.
2355 * Fixed channel adding to global list in IDENTIFY command
2356 reply in server. Affected file silcd/command_reply.c.
2358 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2360 * If the incoming packet type is REKEY or REKEY_DONE process
2361 that packet always synchronously. Fixes yet another MAC
2362 failed error on slow (dialup) connections. Affected file
2363 lib/silcclient/client.c and silcd/server.c.
2365 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Call check_version SKE callback for initiator too. Affected
2368 file lib/silcske/silcske.c.
2370 * Implemented fix for security hole found in the SKE that was
2371 fixed in the specification few days back; the initiator's
2372 public key is now added to the HASH value computation.
2373 Added backwards support for the old way of doing it too, for
2374 old clients and old servers. Affected file is
2375 lib/silcske/silcske.c.
2377 * Enabled mutual authentication by default in SKE. If initiator
2378 is not providing mutual authentication the responder will
2379 force it. This will provide the proof of posession of the
2380 private key for responder. The affected files are
2381 lib/silcclient/protocol.c and silcd/protocol.c.
2383 * Do not cache anymore the server's public key during SKE.
2384 We do mutual authentication so the proof of posession of
2385 private key is done, and if the server is authenticated in
2386 conn auth protocol with public key we must have the public
2387 key already. Affected file silcd/protocol.c.
2389 * Added new global debug variable: silc_debug_hexdump. If
2390 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2391 file lib/silcutil/silclog.[ch].
2393 * Fixed compilation warning due to char * -> const char *.
2394 Affected files lib/silcutil/silcnet.h, and
2395 lib/silccore/silcauth.[ch].
2397 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Fixed CMODE command when new channel key was created. If
2400 the creation failed the old key was removed. Next time giving
2401 same command would crash the server since the old key was
2402 freed already. Affected file silcd/command.c.
2404 * Fixed the silc_server_announce_get_channels to not crash
2405 on reconnect. Affected file silcd/server.c.
2407 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2409 * Added silc_log_set_debug_string function to set a regex
2410 string to match for debug output. Only the function names,
2411 or filenames matching the given debug string is actually
2412 printed. This way it is possible to filter out those debug
2413 strings that user is not interested in.
2415 Fixed a bug in silc_string_regexify.
2417 Affected files lib/silcutil/silclog.[ch], and
2418 lib/silcutil/unix/silcunixutil.c.
2420 * Changed the -d options in both server and Irssi SILC client
2421 to take the debug string as argument. Affected files
2422 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2424 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Added silc_hash_babbleprint to create a Bubble Babble
2427 Encoded fingerprint. The encoding is developed by Antti
2428 Huima (draft-huima-babble-01.txt), and it creates human
2429 readable strings out of binary data. Affected file
2430 lib/silccrypt/silchash.[ch].
2432 * Print the babble print now in addition of fingerprint as well
2433 in Irssi SILC client. Affected files are
2434 irssi/src/fe-common/silc/module-formats.[ch],
2435 irssi/src/fe-common/silc/core/client_ops.c.
2437 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2439 * Fixed a security problem found in SKE. The initiator's
2440 public key too is now added to the HASH hash value creation
2441 which is signed by the responder to create the SIGN value.
2442 This will prevent anyone in the middle to lie to the responder
2443 about the initiator's public key. If this is done now, the
2444 man in the middle will get caught. Updated the protocol
2447 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Better installation directory handling. Configure module
2450 paths and other paths automatically to example_silc* files
2451 in doc/. A patch by toma.
2453 * Fixed compiler warning from MPI library, and from SILC RNG.
2456 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2457 It can be configured with ./configure. A patch by toma.
2459 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2461 * Find correct make to use in prepare-clean. A patch by
2462 toma. Affected file prepare-clean.
2464 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2466 * Added irssi variables use_auto_addr, auto_bind_ip,
2467 auto_bind_port and auto_public_ip.
2469 * Changed the interface for silc_client_send_key_agreement
2470 in lib/silcclient/silcapi.h
2474 irssi/src/silc/core/silc-core.c
2476 lib/silcclient/silcapi.h
2477 irssi/src/silc/core/silc-channels.c
2478 lib/silcclient/client_keyagr.c
2481 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2483 * Added silc_pkcs_public_key_compare to compare two
2484 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2486 * Check that the client who set the founder mode on the
2487 channel is the same client that is giving the founder
2488 mode to itself. It is done by comparing the saved public
2489 key (it is saved even in the authentication is passphrase).
2490 Affected file silcd/command.c.
2492 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2494 * Do not process packet for disconnected socket connection.
2495 Affected file lib/silccore/silcpacket.c.
2497 * Process the DISCONNECT packet through scheduler in the
2498 client library. Affected file lib/silcclient/client.c.
2500 * Fixed the silc_client_packet_parse to not to increase
2501 the packet sequence number if the conn->sock and the
2502 current socket connection is not same. This can happen
2503 for example during key agreement when the conn includes
2504 multiple socket connections (listeners). Affected file
2505 lib/silcclient/client.c.
2507 * The sender of the file transfer request now provides also
2508 the pointer (listener) for the key exchange protocol. If
2509 the listener cannot be created then it sends empty key
2510 agreement and lets the receiver provide the listener.
2512 Added `local_ip' and `local_port' arguments to the
2513 silc_client_file_send. If they are provided they are used,
2514 if not then it will attempt to find local IP address, if
2515 not found or bind fails then the remote client will provide
2518 Affected files are lib/silcclient/client_ftp.c and
2519 lib/silcclient/silcapi.h.
2521 * Extended the FILE SEND command to support defining the
2522 local IP and port for key exchange listener. They are
2523 optional. Affected file irssi/src/silc/core/silc-servers.c.
2525 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Defined to WHOIS command reply the sending of fingerprint
2528 of the client's public key (if the proof of posession of the
2529 corresponding private key is verified by the server).
2530 Updated to the protocol specification.
2532 * Added support of receiving the client's public key's
2533 fingerprint in command reply in client library. Affected
2534 file is lib/silcclient/command_reply.c, and
2535 lib/silcclient/idlist.[ch].
2537 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Do not send over 128 chars long nickname to the server
2540 in NICK command. Affected file lib/silcclient/command.c.
2542 * Do not send over 256 chars long channel names to the server
2543 in JOIN command. Affected file lib/silcclient/command.c.
2545 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Assure that silc_server_close_connection cannot be called
2548 twice for same socket context. Affected file is
2551 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Send error message to application if opening file for
2554 writing during file transfer fails. Affected file is
2555 lib/silcclient/client_ftp.c.
2557 Remove all file transfer sessions for a client that we're
2558 removing from ID cache.
2560 Affected file is lib/silcclient/client_ftp.c.
2562 * Fixed silc_net_addr2bin to return correct address. Affected
2563 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2565 * Fixed file transfer session removing on signoff notify.
2566 Affected file irssi/src/silc/core/silc-servers.c.
2568 * Added the SilcClientFileError to be returned in the monitor
2569 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2570 Affected file lib/silcclient/silcapi.h.
2572 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2574 * Fixed a crash in silc_client_ftp_free_sessions and
2575 silc_client_ftp_session_free_client. Affected file
2576 lib/silcclient/client_ftp.c.
2578 * Added `disabled' field in the SilcChannelEntry in the server
2579 to indicate if the server entry is disabled. Affected file
2580 silcd/idlist.h, silcd/command[_reply].c.
2582 * SILC server adds now /var/run/silcd.pid everytime it is
2583 started. Affected file silcd/silcd.c.
2585 * Added silc_server_packet_send_clients to send a packet to
2586 the provided table of client entries. Affected file
2587 silcd/packet_send.[ch].
2589 * Fixed a crash in client resolving in client_prvmsg.c in
2590 client library. Affected file lib/silcclient/client_prvmsg.c.
2592 * Do not actually remove the client directly from ID cache
2593 during SERVER_SIGNOFF, but invalidate it. This way we
2594 preserve the WHOWAS info for the client. Affected file
2595 silcd/server_util.c.
2597 * Fixed SERVER_SIGNOFF notify handling in the server. The
2598 server is now able to process incoming SERVER_SIGNOFF notify
2599 for a server that it doesn't even know about. It will remove
2600 the clients provided in the notify. Affected file
2601 silcd/packet_receive.c.
2603 * Check for partial packet in data queue after every packet that
2604 was found from the queue. Return and wait for more data if
2605 there is partial data in queue. Affected file is
2606 lib/silccore/silcpacket.c.
2608 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2610 * Added SilcClietFileError enum to indicate error in

2623 irssi/src/fe-common/silc/module-formats.[ch].
2625 * Wrote a help file for FILE command.
2627 * Added silc_rng_global_get_byte_fast to get not-so-secure
2628 random data as fast as possible. Random data is read from
2629 /dev/urandom if available and from the SILC RNG if not
2630 available. It is used in padding generation. Affected file
2631 lib/silccrypt/silcrng.[ch].
2633 * All packets in client library are now processed synchronously.

2646 * Assure that silc_client_notify_by_server_resolve does not
2647 resolve the client information multiple times. If it cannot
2648 be found by the first it cannot be found at all. Affected
2649 file lib/silcclient/client_notify.c.
2651 * Fixed WHOWAS command reply calling. Affected file
2652 lib/silcclient/command_reply.c.
2654 * Removed all references to silc_idlist_get_client from the
2655 Irssi SILC client since that call is internal call used by
2656 the library. The Irssi SILC client will use now client
2657 retrieval functions found in silcapi.h.
2659 * Fixed a bug in resolving nickname info before sending
2660 private message. It used freed memory. Affected file
2661 irssi/src/silc/core/silc-servers.c.

2682 * Added silc_net_localip to return local host's IP address.
2683 Affected file lib/silcutil/silcnet.[ch].
2685 * If key exchange or rekey protocol is active for a connection
2686 parse all packets syncronously since there might be packets
2687 in packet queue that we are not able to process without first
2688 processing packets before them. Affected file silcd/server,
2689 lib/silcclient/client.c.
2691 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2692 whether library should continue processing the packet.
2693 Affected file lib/silccore/silcpacket.h.

2739 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2740 is incomplete and is being resolved, it won't be resolved
2743 Make sure also that USERS command reply does not resolve
2744 twice information. Affected file is
2745 lib/silcclient/command_reply.c.
2747 Make sure that silc_client_get_clients_by_list does not
2748 resolve twice same information.
2750 * Check for valid client->id in the silc_server_free_client_data.
2751 Affected file silcd/server.c.
2753 * Fixed /GETKEY nick@server not to crash if the server entry
2754 is not found. Affected file lib/silcclient/command.c.

2762 Affected file silcd/command.c.
2764 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2766 * Call the silc_server_udpate_servers_by_server in the
2767 primary router that comes back online in the backup resuming
2768 protocol. Otherwise it routes packets wrong. Affected file
2769 silcd/server_util.[ch], silcd/server_backup.c.
2771 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2774 lib/silcutil/silcbuffmt.[ch].
2776 * Redefined the SILC packet header to include the padding
2777 length. Affected file lib/silccore/silcpacket.[ch].
2779 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2780 length for maximum padding up to 128 bytes). Affected
2781 file lib/silccore/silcpacket.h.
2783 * Removed all backwards support for old 0.5.x MAC thingies.
2784 The SILC packet header change makes it impossible to be
2785 backwards compatible.
2787 * Send the ENDING packet with timeout in the backup resuming
2788 protocol. This is to assure that all routers has connected
2789 to the primary router. Affected file silcd/server_backup.c.
2791 * Changed the RNG to take the first IV from random data. It
2792 used to take it from zero actually. Changed the RNG also
2793 to use /dev/urandom during session. /dev/random is used
2794 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2796 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2798 * Changed the SILC packet header to have the first two bytes
2799 (the packet length) encrypted. Affected files aroung the
2800 code tree, lib/silccore/silcpacket.[ch]. Removed the
2801 SilcPacketCheckDecrypt callback. It is not needed anymore
2802 since the silc_packet_receive_process will determine now
2803 whether the packet is normal or special.
2805 * Implemented the unidirectional MAC keys. Affected files
2806 lib/silcske/silcske.c, silcd/protocol.c and
2807 lib/silcclient/protocol.c.
2809 * Implemented the packet sequence number to the MAC computation.
2810 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2811 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2812 lib/silcclient/protocol.c.
2814 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * Allow backup router to announce servers. All servers
2817 announced by backup router are added to the global list
2818 automatically. Update hte server's socket to our primary
2819 router also when backup router announces a server.
2820 Affected file silcd/packet_receive.c.
2822 * Do not update the client->router in the function
2823 silc_server_udpate_clients_by_server if the client is on
2824 global list. We might fail to find any specific server
2825 for locally connected clients and local cell clients. They
2826 should still use the `from' and not `to' as client->router.
2827 This fixes backup router resuming protocol. Affected file
2828 silcd/server_util.c.
2830 * Decrease channel statistics count only if the channel
2831 deletion worked. Affected files are silcd/server.c and
2832 silcd/server_util.c.
2834 * Added silc_server_update_servers_by_server to update origin
2835 of all server entries. Used during backup router protocol.
2836 Affected files silcd/server_util.[ch], silcd/server.c. and
2837 silcd/backup_router.c.
2839 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2840 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2841 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2842 lib/silccrypt/silchmac.c.
2844 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Assure that router cannot reroute the same channel message
2847 to the sender. Affected file silcd/packet_receive.c.
2849 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Made better checks that the channel message is not sent
2852 to the router it came from. Affected file is
2853 silcd/packet_send.c. Fixed memory leak too.
2855 * Announce informations for incoming router connection, but
2856 only after checking if it is replaced by backup router.
2857 Affected file silcd/packet_receive.c.
2859 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Fixed the backup resuming protocol to work in multiple
2862 router environment. Affected file silcd/server_backup.c.
2864 * Route packet only to one router in the function
2865 silc_server_packet_send_to_channel. Affected file is
2866 silcd/packet_send.c.
2868 * Fixed silc_server_send_notify_dest to set the broadcast
2869 flag. Fixed the silc_server_send_notify_topic to actually
2870 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2871 Affected file silcd/packet_send.c.
2873 * Changed the SFTP Filesystem interface. Changed the
2874 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2875 the filesystem operation function. The SilcSFTPFilesystem
2876 is now a context that is allocated by all filesystem allocation
2877 functions and it already includes the operations structure
2878 and filesystem specific context. It is given as argument
2879 now to the silc_sftp_server_start. This made the interface
2880 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2881 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2883 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Changed the backup router adding and getting interfaces
2886 in the server. The router that will be replaced by the
2887 specified backup router is now sent as argument. Affected
2888 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2891 * Added silc_net_addr2bin_ne to return the binary form of
2892 the IP address in network byte order. Affected files
2893 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2895 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Check for existing server ID in silc_server_new_server
2898 and in silc_server_connect_to_router_final and remove the
2899 old entry if it exists. Affected file silcd/packet_receive.c,
2902 * Send the channel message always to only one router, either
2903 in upstream or downstream. Affected file is
2904 silcd/packet_send.c.
2906 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Wrote the definition of the backup resuming protocol to the
2909 protocol specification.
2911 * Removed one redundant channel key generation from normal
2912 server during joining procedure. Removed one redundant
2913 channel key sending from server to router during joining
2914 procedure. Affected file silcd/command.c.
2916 * Made minor bugfixes to the backup router resuming protocol.
2917 Affected file silcd/server_backup.c, server.c.

2922 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2925 * Implemented the backup resuming protocol that is used to
2926 resume the primary router position in the cell after the
2927 primary router comes back online. Affected files
2928 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2929 and silcd/server_util.[ch].
2931 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Sleep two (2) seconds after sending QUIT command to server.
2934 Affected file lib/silcclient/command.c.
2936 * Assure that if outgoing data buffer is pending do not force
2937 send any data. Affected file silcd/packet_send.c.
2939 * Assure that if outgoing data buffer is pending do not force
2940 send any data. Affected file lib/silcclient/client.c.
2942 * Implemented the backup router support when the primary router
2943 goes down. The servers and routers can now use the backup
2944 router as new primary router without loosing connectivity.
2946 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2949 in the server to indicate disabled entry. All data read
2950 from the connection will be ignored and no data is sent
2951 for entry that is disabled. Affected files are
2952 silcd/idlist.h, silcd/server.c.
2954 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2956 * Created SFTP client and server test programs in the
2957 lib/silcsftp/tests directory.
2959 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Implemented memory filesystem (virtual filesystem) for
2962 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2965 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Implemented the SFTP (SSH File Transfer Protocol) to the
2968 lib/silcsftp. It includes SFTP client and SFTP server
2971 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Moved lib/silccore/silcprotocol.[ch] to the
2974 lib/silcutil library.
2976 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2977 take variable argument list pointer as argument. Affected
2978 file lib/silcutil/silcbuffmt.[ch].
2980 * Added silc_buffer_set function that is used to set data
2981 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2982 Affected file lib/silcutil/silcbuffer.h.
2984 * Changed various routines in the core library to use the new
2985 silc_buffer_set instead of allocating new buffer only for
2988 * Added 64-bit value formatting and unformatting support to the
2989 silc_buffer_[un]format routines. Affected file is
2990 lib/silcutil/silcbuffmt.[ch].
2992 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2993 to includes/bitmove.h.
2995 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2997 * Fixed channel user mode saving in client library. Affected
2998 file lib/silcclient/command[_reply].c.
3000 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Defined the file transfer to the SILC Protocol. Added
3003 new packet type SILC_PACKET_FTP and defined File Transfer
3004 Payload. The mandatory file transfer protocol is SFTP
3005 (SSH File Transfer Protocol). Affected file in addition
3006 of the internet draft is lib/silccore/silcpacket.h.
3008 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3009 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3010 is used as part of backup router protocol when the primary
3011 router of the cell is back online and wishes to resume
3012 the position as primary router.
3014 * Redefined the MAC generation keys in the protocol. The
3015 same key is not used anymore in both direction. Both
3016 direction will now use different keys for sending and
3017 receiving. This fixes a potential security flaw. This
3018 change causes incompatibilities in the protocol.
3020 * Redefined also the MAC computation from the packet.
3021 An packet sequence number is now added to the MAC
3022 computation. This prevents possible replay attacks against
3023 the protocol. This change too causes incompatibilities
3026 Added `sequence' field to the SilcPacketContext to hold
3027 the current sequence number for the packet.
3029 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Added `created' field to the SilcIDListData in the file
3032 silcd/idlist.h to indicate the time when the entry was
3035 * Added `created' field to the SilcChannelEntry too. Affected
3036 file silcd/idlist.h.
3038 * Added `creation_time' aguments to all the announcement functions
3039 in the server. If it is provided then only the entries that
3040 was created after the provided time frame are actually
3041 announced. Affected file silcd/server.[ch].
3043 * The protocol says that the Channel ID's IP address must be
3044 based on the router's IP address. Added check for this in
3045 the silc_server_new_channel when processing incoming New Channel
3046 Payload. Affected file silcd/packet_receive.c.
3048 * Print out the correct version with --version in SILC client.
3049 Affected file irssi/src/silc/core/silc-core.c.
3051 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Fixed WHOWAS command to check for completnes of the client
3054 entry always, not just when the command is coming from client.
3055 Affected file silcd/command.c.
3057 * Added new function silc_server_packet_queue_purge to purge the
3058 outgoing data queue to the network. After the function returns
3059 it is guaranteed that the outgoing packet queue is empty.
3060 Affected file silcd/packet_send.[ch].
3062 * Purge the outgoing packet queue in the rekey protocol's final
3063 callback to assure that all rekey packets go to the network
3064 before quitting the protocol. Affected file silcd/server.c.
3066 * Added silc_client_packet_queue_parse as similar function as
3067 in server to the client library. The affected file is
3068 lib/silcclient/client.c.
3070 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Splitted silcd/server.c and created silcd/server_util.[ch]
3073 for utility functions.
3075 * Added new socket flag SILC_SF_DISABLED to indicate that the
3076 connection is open but nothing can be sent to or received from
3077 the connection. Affected file lib/silcutil/silsockconn.[ch].
3078 The checking for disabled socket is checked in the low level
3079 silc_socket_write and silc_socket_read functions.
3081 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Allow only nicknames and channel names that fits into the
3084 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3086 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * When processing JOIN command reply in server check that if
3089 the channel exists in our global list we'll move it the local
3090 list. Affected file silcd/command_reply.c.
3092 * Fixed the check whether client is joined on the channel already
3093 in JOIN command. Affected file lib/silcclient/command.c.
3095 * Fixed the JOIN command reply to check whether the channel
3096 already exists. Affected file lib/silcclient/command_reply.c.
3098 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3100 * Added silc_ske_status_string to map the SKE error numbers
3101 to readable strings. The affected files are
3102 lib/silcske/silcske[_status].[ch].
3104 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Do not show the private channels on the WHOIS channel list
3107 as it is not allowed by the protocol. The affected file is
3110 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3112 * Assure that the packet length digged from the actual packet
3113 is something sensible in the silc_packet_decrypt_rest_special
3114 in lib/silccrypt/silcpacket.c.
3116 * Free and NULL the allocated pointer in silc_hmac_alloc if
3117 the HMAC allocation fails. The affected file is
3118 lib/silccrypt/silchmac.c.
3120 * Print the selected security properties to the log files in
3121 the server. Affected file silcd/protocol.c.
3123 * Add SKE's reference counter even if calling the completion
3124 callback manually. Otherwise it goes negative, although it
3125 does not cause any problems. The affected file is
3126 lib/silcske/silcske.c.
3128 * Remove the client entry with short timeout after giving the
3129 KILL command. Affected file lib/silcclient/command.c.
3131 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3132 case all found clients are already disconnected (WHOWAS would
3133 found them) in the server. Affected file silcd/command.c.
3135 * Update the last_receive (time of last data received) to be
3136 updated only when received private or channel message so that
3137 the idle time showed in WHOIS makes more sense.
3139 * Added boolean field `valid' in to the SilcClientEntry in the
3140 client library to indicate whether the entry is valid or not.
3141 This fixes the nickname change bug on channel when changing
3142 the nickname to be same than the old (like nick to Nick) the
3143 nickname formatter doesn't set the new nick anymore to Nick@host.
3144 Affected file lib/silcclient/idlist.[ch].
3146 * Now actually fixed the nickname changing on disconnection.
3147 Added new function silc_change_nick to the Irssi SILC Client.
3148 Affected file irssi/src/silc/core/client_ops.c,
3149 irssi/src/silc/core/silc-nicklist.[ch].
3151 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3153 * Check that the public key exists in the GETKEY command before
3154 trying to encode it. Affected file silcd/command.c.
3156 * Print some notifications on received public keys with GETKEY
3157 command in the Irssi SILC Client. Affected files are
3158 irssi/src/fe-common/silc/module-formats.[ch],
3159 irssi/src/silc/core/client_ops.c.
3161 * Use IDENTIFY command to resolve the server information in the
3162 GETKEY command instead of INFO command. Affected file
3163 lib/silcclient/command.c.
3165 * All command reply functions in the client library now calls
3166 the pending command reply callbacks even if an error has
3167 occurred. The server has done this a long time and now it was
3168 time to move the client library to this as well. Now all
3169 errors can be delivered back to the pending command reply
3170 callbacks if necessary. Affected files are
3171 lib/silcclient/command[_reply].[ch].
3173 * Change the nickname on disconnection back to the username
3174 because in reconnect the server will enforce it to it anyway.
3175 Affected file irssi/src/silc/core/silc-servers.c.
3177 * Fixed a config file parsing bug in the Irssi SILC client.
3178 Affected file irssi/src/silc/core/clientconfig.c.
3180 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * When printing the channel mode on JOIN, verify that the
3183 channel key and channel's HMAC are valid. Affected file
3184 irssi/src/silc/core/client_ops.c.
3186 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3189 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3190 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3192 * Removed channel key rekey task deleting from the function
3193 silc_server_save_channel_key. Affected file silcd/server.c.
3194 Added explicit timeout task context instead that is used to
3195 delete the task if we are registering a new task before the
3196 new task has elapsed.
3198 * When channel key rekey occurs the client library now saves
3199 the old channel key for a short period of time (10 seconds) and
3200 is able to use it in case some is still sending channel
3201 messages encrypted with the old key after the rekey. Affected
3202 file lib/silcclient/[idlist.h|client_channel.c].
3204 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Added check to the silc_server_new_id_real to not accept
3207 new ID if it is the sender's own ID. Affected file is
3208 silcd/packet_receive.c.
3210 * Assure that we do not announce ourself or the one we've
3211 sending our announcements when we're router and are announcing
3212 servers to our primary router. Affected file silcd/server.c.
3214 * Fixed silc_server_command_identify_check_client to assemble
3215 correct WHOIS packet. It send corrupted WHOIS packet and
3216 caused problem with router to router connections. Affected
3217 file silcd/command.c.
3219 Fixed also silc_server_command_whois_check the same way
3220 as for the IDENTIFY command.
3222 * Added new SilcIDListStatus to the server in the SilcIDListData
3223 structure. The status now includes the current status of
3224 the entry (like registered, resolved etc.). Affected file
3225 silcd/idlist.[ch]. Defined a bunch of different status types
3226 as well. This replaced the old boolean registered field as well.
3228 Added resolve_cmd_ident field to the SilcClientEntry structure
3229 too so that if the entry is for example being resolved so
3230 another command may attach to the same pending command reply
3231 without requiring to resolve the same entry again. This concept
3232 should optimize the WHOIS and the IDENTIFY resolving under
3233 heavy load by taking away unnecessary resolving for entries
3234 that are being resolved already.
3236 Added support for adding multiple pending commands for one
3237 command idenfier. Affected file silcd/command[_reply].[ch].
3239 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3240 before deleting the data. Otherwise the hash table will have
3241 freed data in comparison functions. Affected file is
3242 silcd/command_reply.c.
3244 * Fixed silc_idlist_replace_client_id to add the new entry to
3245 the cache with NULL nickname. Otherwise there will be invalid
3246 memory as the nickname after the nickname is freed. Affected
3247 file silcd/packet_receive.c.
3249 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3250 saved into wrong slots because the previous number of entries
3251 was not taken into account. Affected file silcd/idlist.c.
3252 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3254 * If we are router and we receive JOIN notify to a channel that
3255 does not have any users then notified client is marked as the
3256 channel founder, as it is it. The affected file is
3257 silcd/packet_receive.c
3259 * Added to the extended hash table API's table_del_*ext functions
3260 the destructor as argument too, so that the caller can decide
3261 which destructor to use or whether to use destructor at all.
3262 Affected file lib/silcutil/silchashtable.[ch].
3264 * Fixed ID Cache purging. It actually deleted the entries from
3265 the hash table after the data was freed. The hash table ended
3266 up comparing freed memory. The affected file is
3267 lib/silccore/silcidcache.c.
3269 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Fixed Irssi SILC client's KILL command's HELP syntax.
3273 * The USERS command now resolves the detailed user information
3274 if the userinfo field is missing. Affected file is
3275 lib/silcclient/command_reply.c.
3277 * Do not print error in silc_file_read if the read file does
3278 not exist. Just silently return NULL. Affected file is
3279 lib/silcutil/silcutil.c.
3281 * Fixed the silc_log_output to not wine about NULL filename
3282 and to not create some bogus " " filename. Affected file is
3283 lib/silcutil/silclog.c.
3285 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * Fixed various printing bugs on the user interface in the
3288 Irssi SILC Client. Minor changes that were forgotten from
3291 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Fixed the configure.in.pre and the compilation and distribution
3294 environment to support the new autoconf 2.52. That version is
3295 now required to compile the CVS trunk.
3297 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3300 to generally parse user@fqdn format strings. Affected file
3301 lib/silcutil/silcutil.c.
3303 * Added nickname_format and nickname_force_format fields to the
3304 SilcClientParams structure. The first one defines the format
3305 for the nicknames that the library will enforce if the receives
3306 multiple same nicknames. The second one is boolean value and
3307 can be used to force the library to always enforce the format
3308 to the nicknames regardles whether there are multiple nicknames
3309 or not. This configurable formatting was employed to flexibly
3310 support accessing multiple nicknames from the user interface.
3311 The userinterface can now set the nicknames to what ever format
3312 they prefer. Affected file lib/silcclient/silcapi.h.
3314 Added function silc_client_nickname_format to the file
3315 lib/silcclient/idlist.c. It performs the nickname formatting.
3317 Added new field `hostname´ to the SilcClientEntry context.
3318 It holds the hostname of the client. Affected file is
3319 lib/silcclient/idlist.h.
3321 * Irssi SILC Client sets the nicknames in nick@hostn format.
3322 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3323 irssi/src/silc/core/silc-core.c.
3325 The WHOIS printing now also shows both the real nickname and
3326 the formatted nickname so that user knows how to access the
3327 user if there are multiple same nicknames cached. Affected
3328 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3329 printing formatting too to take the hostname now as a separate
3330 argument. The Affected file is
3331 irssi/src/fe-common/silc/modules-formats.[ch].
3333 * Changed the silc_client_get_clients_local to accept the formatted
3334 nickname as argument. It accepts the real nickname too but the
3335 formatted nickname can be used to find the true entry from
3336 multiple entries. Affected file lib/silcclient/silcapi.h and
3337 lib/silcclient/idlist.c.
3339 * Added nickname_format_parse field to the SilcClientParams.
3340 It is a callback function provided by the application to parse
3341 the nickname out of the formatted nickname string. The library
3342 calls it to get the nickname from the formatted string. Since
3343 the application generally knows better the format of the nickname
3344 string it parses it instead of the library, even though library
3345 encodes the formatted string. If the callback function is not
3346 provided then the library will use the string as is. The
3347 affected file is lib/silcclient/silcapi.h.
3349 * All the nickname strings passed to the client library in
3350 commands are now expected to be formatted nickname strings.
3351 If the command does not support the formatted nickname string
3352 it will assume that the sent string is the actual nickname.
3353 Affected file lib/silcclient/command.c.
3355 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3357 * Added public key authentication support to OPER and SILCOPER
3358 commands in the client library. Affected file is
3359 lib/silcclient/command.c.
3361 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Changed the get_auth_methdod client operation to be asynchronous.
3364 It can be async if the application resolves the authentication
3365 method from the server during the negotiation. Added new
3366 SilcGetAuthMeth completion callback that the application will
3367 call after resolving the authentication method.
3369 Added function silc_client_request_authentication_method that
3370 the application can use to resolve the authentication method
3371 from the server. Added also SilcConnectionAuthRequest callback
3372 that the library will call after the server has replied. The
3373 application can call this function if it does not know the
3374 current authentication method.
3376 Affected files are lib/silcclient/client.c and
3377 lib/silcclient/silcapi.h.
3379 * The Irssi SILC client now automatically resolves the authentication
3380 method incase any configuration information is not present (and
3381 currently there never is). The affected file is
3382 irssi/src/silc/core/client_ops.c.
3384 * Fixed public key authentication from the client library.
3385 Affected file lib/silcclient/protocol.c. Changed also the
3386 protocol specification about the public key authentication in
3387 the connection authentication protocol. The actual data to be
3388 signed is now computed with a hash function before signing.
3390 * Fixed the public key authentication from the server as well.
3391 Affected file silcd/protocol.c.
3393 * Removed the mlock()'s from the memory allocation routines.
3394 Affected file lib/silcutil/silcmemory.c. The ./configure does
3395 not check anymore for the mlock(). Affected file is
3398 * Fixed USERS command in server to allow the execution of the
3399 command for private and secret channels if the client sending
3400 the command is on the channel. Affected file silcd/command.c.
3402 * Fixed silc_client_get_clients_local to return the clients
3403 count correctly. It could return wrong value. Affected file
3404 lib/silcclient/idlist.c.
3406 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3409 types. The assembler optimizations seemed not to like 64-bit
3410 data types. The assmebler optimizations thus are now enabled
3411 also for BSD systems as opposed to only enable them for Linux.
3413 * Do not check for threads at all on BSD systems. Affected
3414 file configure.in.pre.
3416 * Removed -n and -h options from the Irssi SILC Client since
3417 they are not used in silc.
3419 * Fixed the prime generation to assure that the first digit
3420 of the generated random number is not zero since our conversion
3421 routines does not like number strings that starts with zero
3422 digit. If zero digit is seen the random number is regenerated.
3423 This caused some corrupted RSA keys when the zero first digit
3424 was met. Affected file lib/silcmath/silcprimegen.c.
3426 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Fixed WIN32 configuration in the ./configure script.
3429 Fixed to include xti.h on environments that has it.
3430 Patches by Carsten Ilchmann and andrew.
3432 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Changed the silc_id_create_client_id to be collision
3435 resistant. It is now assured that there cannot be created
3436 two same client ID's. I suspect that some weird bugs in
3437 the server were actually caused by duplicate Client IDs.
3438 Affected file silcd/serverid.[ch]. A router receiving
3439 new ID now also assures and informs the sending server
3440 if the ID caused collision.
3442 * Changed the silc_id_create_channel_id to also assure that
3443 there are no collisions.
3445 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3447 * Statement about ignoring the Mutual Authentication flag when
3448 performing rekey with PFS was a bit misleading. It is ignored
3449 if it was set in the initial negotiation, it cannot be even
3450 set in the rekey. Fixed in the ke-auth draft. Started the
3451 new versions of the protocol drafts in the doc/.
3453 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Fixed a bug in silc_client_command_identify_save when saving
3456 new channel information. The channel name was no duplicated
3457 and caused crash on exit. Affected file is
3458 lib/silcclient/command_reply.c.
3460 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Fixed the getkey command handling in the server. Send just
3463 empty OK reply to the sender if the key could not be fetched
3464 (but everything else was ok, like the key just was not available).
3465 Changed the public key parameter to optional in the protocol
3466 specs so that empty OK reply can be sent. Affected file
3469 Added a message to Irssi SILC client to tell to user if the
3470 server did not return a public key.
3472 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Fixed a channel key regeneration bug. It registered new
3475 timeout tasks exponentially until all system resources were
3476 used. Affected file silcd/server.c.
3478 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Added the SILC Document generator to the scripts/silcdoc.
3481 It can be used to generate the Toolkit Reference Manual out
3482 of the source tree. Internally it will also use the RoboDoc
3483 generator now imported in util/robodoc.
3485 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Added couple of return's in rekey protocol if error orccurred
3488 during the protocol. The execution must be terminated.
3489 Affected file silcd/protocol.c. Also, terminate the protocol
3490 always with timeout.
3492 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * The client's Client ID was created initally from the wrong
3495 nickname (it could have been in format nick@host) in the
3496 silc_server_new_client. Affected file silcd/packet_receive.c
3498 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Added some SILC_LOG_ERROR's to various error conditions
3501 if client could not be added to ID cache. Affected files
3502 silcd/packet_receive.c and silcd/server.c.
3504 * When client's sock->user_data is freed, NULL also the
3505 client->router and client->connection pointers. Added check
3506 for these pointers being NULL to various places around the
3507 code. Affected file silcd/server.c.
3509 * Added client->data.registered == TRUE checks to various
3510 places around the code to assure that unregistered client's
3511 are not handled when it is not allowed. Affected file
3514 * Added `bool registered' fields to all
3515 silc_idlist_[server|client]_get_* routines to indicate whether
3516 the fetched client needs to be registered or not. Affected
3517 file silcd/idlist.[ch].
3519 * Add your own entry as registered to the ID cache in the
3520 server. Affected file server.c.
3522 * Fixed a bug in silc_server_new_server. The SilcServer was
3523 set as the new server's context instead of SilcServerEntry.
3524 This naturally caused some weird bugs.
3526 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * Do not delete the channel rekey task when adding it
3529 for in silc_server_create_channel_key.
3531 * Changed the silc_server_create_channel_key to return
3532 TRUE or FALSE to indicate the success of the channel key
3535 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Fixed MSVC++ project files and added missing files to
3538 Makefiles under win32/.
3540 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3542 * Do not add TCP_NODELAY flag if the operating system
3543 does not have it defined. Affected files are
3544 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3546 * Fixed buffer overflow from Irssi SILC Client. Affected
3547 file irssi/src/fe-common/core/themes.c.
3549 * Fixed double free in client library in the file
3550 lib/silcclient/client.c when disconnecting from server.
3552 * Applied double free patch from cras to Irssi SILC client.
3553 Affected files irssi/src/core/[modules/expandos].c
3555 * Fixed the disconnection handling to Irssi SILC Client.
3556 The application must call silc_client_close_connection
3557 in ops->connect client operation in case of failure of
3558 the connection. Affected file is
3559 irssi/src/silc/core/client_ops.c.
3561 * Do not set sock->protocol to NULL in the function
3562 silc_client_close_connection after executing the protocol's
3563 final callback since the sock might not be valid anymore.
3564 Affected file lib/silcclient/client.c.
3566 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3568 * Do not enable SILC_THREADS if the linking with libpthread
3569 did not happen. Affected file configure.in.pre.
3571 * Added notion to protocol specification that server must
3572 verify the sent authentication payload with CMODE when
3573 setting the channel founder key. Implemented it to the
3574 server. Affected file silcd/command.c.
3576 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Added _EXTRA_DIST SILC distribution variable to the
3579 distributions file. It is used to conditionally add extra
3580 files or directories to the specific distribution. Affected
3581 files ./prepare, Makefile.am.pre and distributions.
3583 Removed the `_' from the start of the distribution names.
3586 * Added README.WIN32 for instructions to compile the Toolkit
3589 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3591 * Fixed a double free in disconnection in the server. Affected
3592 file is silcd/server.c.
3594 * Fixed the lib/silcske/groups.c to work now also with GMP
3595 MP library. The string conversion did not work when using
3596 specific base and the base is indicated in the string as well.
3598 * Created win32/ directory which now includes MSVC++ specific
3599 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3600 It will appear only in the toolkit distribution
3602 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Changed the key material distribution function in case when
3605 the hash output is too short. The data is now concatenated
3606 a bit differently than it used to. Made the change to the
3607 SKE protocol specification.
3609 * Added better GMP detection to configure.in.pre. A patch
3612 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3614 * Fixed a minor bug in SKE that might cause some problem on
3615 some platforms. Affected file lib/silcske/silcske.c.
3617 * Added the cookie checking for initiator in the SKE. It checks
3618 that the responder returns the sent cookie unmodified. The
3619 affected file is lib/silcske/silcske.c. Added new SKE
3620 error type INVALID_COOKIE that can be sent during the
3621 negotiation. Fixed some memory leaks as well.
3623 * Added the "invalid cookie" error message to Irssi SILC client's
3626 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Added `task_max' field to the SilcClientParams to indicate
3629 the maximum tasks the scheduler can handle. If set to zero,
3630 default values are used. Affected file lib/silcclient/silcapi.h.
3632 * Fixed memory leaks in silc_client_close_connection. Affected
3633 file lib/silcclient/client.c.
3635 * Added silc_client_del_client_entry to client library to free
3636 all memory of given client entry. Affected file is
3637 lib/silcclient/idlist.[ch].
3639 * Added new functions silc_client_del_channel and
3640 silc_client_del_server to delete channel and server entries.
3641 Affected file lib/silcclient/[silcapi.h/idlist.c].
3643 * Removed silc_client_del_client_by_id from silcapi.h.
3645 * Fixed the INFO command to return the server's own info
3646 correctly when querying by Server ID. Affected file is
3649 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Removed the non-blocking settings in WIN32 code in the
3652 silc_sock_[read/write] and added SleepEx instead. Affected
3653 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3654 of input data is now checked with FIONREAD and ioctlsocket.
3656 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * Call silc_schedule_task_del_by_context in the
3659 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3660 Affected file lib/silccore/silcprotocol.c.
3662 * Call silc_protocol_cancel for active protocols in the
3663 silc_server_close_connection if the funtion
3664 silc_server_free_sock_user_data has not been called.
3665 Affected file silcd/server.c.
3667 * Generic tasks cannot be deleted using the del_by_fd
3668 task deleting function since generic tasks does not match
3669 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3671 * Added a notion to SILCOPER help file that the SILCOPER works
3672 only on router server, not on normal server.
3674 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3676 * Added for WIN32 support for the new scheduler as well.
3677 Affected file lib/silcutil/win32/silcwin32schedule.c.
3679 * Fixed the SHA1 implementation to work on various platforms.
3681 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3684 API. It is part of the scheduler now. Everything else is
3685 as previously but some functions has changed their names.
3686 Checkout the lib/silcutil/silcschedule.h for the interface.
3687 Updated all applications to use the new interface. Affected
3688 files are lib/silcutil/silcschedule.[ch].
3690 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3692 * Found a bug in the SKE implementation. The HASH value,
3693 specified by the protocol, was not computed correctly. The
3694 public key of the responder was not added to the computation
3695 even though it is mandatory. Affected file lib/silcske/silcske.c.
3696 This unfortunately causes incompatibilities with older
3697 clients and servers.
3699 * Added WIN32 specific network init and uninit functions:
3700 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3701 the Winsock2. Affected file lib/silcutil/silcnet.h and
3702 lib/silcutil/win32/silcwin32net.c.
3704 * Set the socket always to nonblocking mode on WIN32 after
3705 reading data or writing data. Affected file is
3706 lib/silcutil/win32/silcwin32sockconn.c.
3708 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3710 * Fixed various compilation problems under WIN32. Affected
3711 files lib/silcutil/win32/silcwin32thread.c and
3712 lib/silcutil/win32/silcwin32schedule.c.
3714 * Removed all _internal.h #includes from public header
3715 files. Internal headers must never be included from
3718 Removed also the lib/silcske/payload_internal.h file.
3720 * All include files that may be needed (public and some others
3721 included by the public headers) by application developers are
3722 now copied to the ./includes directory. It does not copy any
3723 internal headers. Affected file Makefile.defines.pre and all
3724 Makefile.am's under lib/ and subdirs.
3726 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3728 * Do not change the ~/.silc directory's permissions automatically.
3729 Affected file irssi/src/silc/core/clientutil.c.
3731 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Do not cancel the protocol in silc_server_close_connection
3734 it might cause recursion. Now cancelled in the function
3735 silc_server_free_sock_user_data. Affected file silcd/server.c.
3737 * Fixed the silc_server_remove_clients_by_server to regenerate
3738 the channel keys correctly finally. Added also new function
3739 silc_server_remove_clients_channels to actually do it.
3740 Affected file silcd/server.c.
3742 * Fixed the silc_server_new_channel to not crash by giving
3743 wrong router to the new channel. Affected file is
3744 silcd/packet_receive.c.
3746 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3748 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3749 which is given as argument to the silc_client_alloc now.
3750 It can be used to configure the client and set various parameters
3751 that affect the function of the client.
3753 * The USERS command in server did not check whether the channel
3754 is private or secret. Affected file silcd/command.c.
3756 * Added new argument to the USERS command in protocol specification.
3757 The USERS command now can take the channel name as argument
3758 as well. Added support for this in client and server and
3759 updated the protocol specs.
3761 * Completed the GETKEY command in client. It can be now used
3762 to fetch also servers public key not only some clients.
3763 Affected files lib/silcclient/command[_reply].c.
3765 * Added silc_client_get_server to return server entry by the
3766 server name. Affected files lib/silcclient/silcapi.h and
3769 * Redefined the IDENTIFY command in protocol specification to be
3770 more generic. It now can be used to query information about
3771 any entity in the SILC Network, including clients, servers and
3772 channels. The query may be based either the entity's name
3773 or the ID. Added support for this in both client and server.
3775 Affected files silcd/command.c and lib/silcclient/command.c
3776 and command_reply.c.
3778 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3779 the _from_client and _from_server functions. Affected file
3782 * Added silc_client_get_channel_by_id_resolve to the file
3783 lib/silcclient/silcapi.h to resolve channel information by
3784 its ID. Added also silc_client_get_channel_by_id that
3785 does not resolve it from the server.
3787 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3789 * Added SilcServerEntry context into the client library
3790 to represent one server. The INFO command now allocates
3791 these to save the resolved server info. For now on the
3792 client library will also keep information about servers,
3793 connected and resolved with INFO.
3795 The INFO command now allocates the SilcServerEntry context
3796 and saves the server info there. The COMMAND_REPLY in
3797 the INFO now returns the parameters to application in
3798 same order as defined in the protocol specification.
3800 The entries are cached in the client->server_cache.
3802 * The INFO command is now issued after received the Client ID
3803 from the server. Affected file lib/silcclient/client.c.
3805 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3806 to the application as the mode changer might be server.
3807 It is guaranteed that NULL is not returned anymore to the
3808 application. Affected file lib/silcclient/client_notify.c.
3810 The ID Type is now also passed to the application so that
3811 it can check whether the returned entry is SilcClientEntry
3814 Added new function silc_client_get_server_by_id to return
3815 the server entry by ID. Affected files are the
3816 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3818 * Do not create the channel in the Irssi SILC Client when issuing
3819 the JOIN command but when received the sucessful JOIN command
3820 reply. Otherwise the channel might get created even though we
3821 could not join it. The Affected file is
3822 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3824 * Fixed a channel joining bug in router. The router must also
3825 check the channel modes, invite and ban lists etc. when serving
3826 the JOIN command sent by normal server. Affected file is
3827 silcd/command.c. The router now resolves the client's
3828 information from the server who sent the JOIN command if it
3829 does not know it, and processes the JOIN command only after
3832 * Changed the SilcCommandCb to take new argument; void *context2.
3833 Affected file lib/silccore/silccommand.h
3835 The second argument in the command callbacks in the server now
3836 includes the SilcServerCommandReplyContext if the command was
3837 called as pending command callback from the command reply.
3838 Otherwise it is NULL. When called as pending the status of the
3839 command reply will be checked and if it was erronous the
3840 error will be sent to the original sender of the command.
3841 This way the client always receives the error messages even
3842 though the server was actually the one who received the error
3843 when it resent the command to router, for example. Affected
3844 files silcd/command[_reply].[ch].
3846 * Fixed sending WHOWAS command's error message to client if
3847 the requested client could not be found. It was missing.
3850 * Changed the CMODE and CUMODE commands reply arguments in the
3851 protocol specification. The Channel ID is now sent in both
3852 of the commands to identify the channel. Implemented this
3853 new feature to the client and server. Affected files
3854 lib/silcclient/command_reply.c and silcd/command.c.
3856 * Made better checks for invite and ban lists in the JOIN
3857 command in server. Affected file silcd/command.c.
3859 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3861 * The server now performs the incoming host IP/DNS lookup
3862 using the silc_socket_host_lookup and thus does not block
3863 the server anymore. Affected file silcd/server.c.
3865 * Completed the multi-thread support for SILC Scheduler in
3866 the lib/silcutil/silcschedule.c.
3868 * Fixed the configure.in.pre to detect the pthread correctly
3871 * Fixed a deadlock in silc_task_queue_wakeup in the file
3872 lib/silcutil/silctask.c.
3874 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3876 * Added new function silc_schedule_wakeup that is used in
3877 multi-threaded environment to wakeup the main thread's
3878 schduler. It needs to be used when a thread adds a new task
3879 or removes a task from task queues. After waking up, the
3880 scheduler will detect the task queue changes. If threads
3881 support is not compiled in this function has no effect.
3882 Implemented the wakeup mechanism to both Unix and WIN32
3883 systems. Affected files are lib/silcutil/silcschedule.[ch],
3884 lib/silcutil/unix/silcunixschedule.c and the
3885 lib/silcutil/win32/silcwin32schedule.c.
3887 * Added new function silc_task_queue_wakeup to wakeup the
3888 scheduler by the specified task queue. Affected file
3889 lib/silcutil/silctask.[ch].
3891 * The silc_socket_host_lookup_start now wakes up the scheduler
3892 after adding the timeout task. Affected file is
3893 lib/silcutil/silcsockconn.c.
3895 * The silc_socket_host_lookup is synchronous now if the threads
3896 support is not compiled in. However, the callback is still
3897 called asyncronously through the scheduler, anyway. Affected
3898 file lib/silcutil/silcsockconn.c.
3900 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3902 * Added new function silc_socket_host_lookup to perform
3903 asynchronous IP and FQDN lookups for the socket connection.
3904 Affected files lib/silcutil/silcsockconn.[ch].
3906 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3908 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3909 that may or may not compile the mutex support in.
3911 Changed the silc_mutex_alloc interface. It allocates the
3912 mutex now to the sent pointer and returns TRUE or FALSE.
3914 Affected file lib/silcutil/silcmutex.h.
3916 * Wrote the SILC Task Queue interface to support multi-threads.
3917 Affected file lib/silcutil/silctask.[ch].
3919 * Wrote the SILC Scheduler to support multi-threads. Affected
3920 file lib/silcutil/silcschedule.c.
3922 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3924 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3925 in lib/silcutil/win32/.
3927 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Defined SILC Mutex API and SILC Thread API and implemented
3930 them for Unix. Affected files are
3931 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3932 lib/silcutil/unix/silcunixmutex.c and
3933 lib/silcutil/unix/silcunixthread.c.
3935 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3937 * Fixed the silc_server_remove_clients_by_server's channel
3938 key re-generation. The hash table handling was incorrect
3939 and would not work with many channels. Affected file is
3942 * Fixed some memory leaks around the server code.
3944 * Rewrote the silc_server_get_users_on_channel to support IPv6
3945 based Client ID's. Affected file silcd/server.c.
3947 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3948 specification. However, a separate document must be written
3949 to define the detailed signing procedure and the payload
3950 associated with the flag. Defined the flag to the
3951 lib/silccore/silcchannel.h as well.
3953 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3955 * Changed the dynamic tables to static size tables in the
3956 lib/silccrypt/silchmac.c.
3958 * Removed GCC dependencies from the code. A patch by cras.
3960 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Do not show the error "Error receiving packet bla bla"
3963 in server if it really was not an error (-2 means that reading
3964 is pending). Affected file silcd/server.c.
3966 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3968 * Fixed a possible crash in silc_server_remove_clients_by_server
3969 in silcd/server.c. Fixed there also some memory leaks.
3971 * Fixed the silc_idlist_replace_client_id. It could replace
3972 wrong key in the hash table. Affected file silcd/idlist.c.
3974 * Do not check whether there are global users on the channel
3975 if the channel->global_users is FALSE. Affected functions
3976 silc_server_remove_from_one_channel and
3977 silc_server_remove_from_channels in silcd/server.c. Also,
3978 do not check if the removed client is local as we can be
3979 sure that global client was not removed from the channel
3980 and checking for global users is not needed.
3982 * The silc_server_remove_clients_by_server now re-generates
3983 the channel keys correctly for those channels that had
3984 clients removed from them. Affected file silcd/server.c.
3986 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3988 * Found the reason of random crashes in the server. We weren't
3989 ignoring the SIGPIPE signal (which can be sent in write())
3990 and it crashed the server. Affected file silcd/silcd.c.
3992 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Assure that sock->user_data is not NULL in the function
3995 silc_server_packet_send in silcd/packet_send.c.
3997 * Disconnect the remote connection if it could not be added
3998 to any ID lists in the server. The affected file is
4001 * Check in silc_server_packet_send[_real/dest] that the
4002 socket is not disconnecting and ignore the data if it is.
4003 Affected file silcd/packet_send.c.
4005 * Define inline to __inline on native WIN32 compilation.
4006 Affected file includes/silcwin32.h.
4008 * Added some explicit type casts for inline code since MSVC
4009 require them. Affected files lib/silcutil/silcbuffer.h,
4010 lib/trq/silcdlist.h and lib/trq/silclist.h.
4012 * Print warning in log files from now on if the packet
4013 decryption fails. Affected file silcd/server.c.
4015 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4017 * Changed the `say' client operation's interface to accept
4018 new `type' argument to indicate the type of the message sent
4019 by the library. The application may filter the library's
4020 messages according the type. The affected file is the
4021 lib/silcclient/silcapi.h.
4023 * Added two new functions to lib/silcclient/silcapi.h:
4024 silc_client_del_client and silc_client_del_client_by_id.
4025 Affected file lib/silcclient/idlist.c.
4027 * Moved the clientincludes.h from includes/ to silc/ and
4028 serverincludes.h from includes/ to silcd/.
4030 * The modes for the CMODE and CUMODE are now passed as
4031 uint32 for application with COMMAND_REPLY. The affected
4032 file is lib/silcclient/command_reply.c.
4034 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4036 * /WHOIS without arguments shows client's own information.
4037 Affected file lib/silcclient/command.c.
4039 * Changed PING to not accept any arguments. The specs
4040 says that client can ping only the connected server so
4041 requiring an argument is not needed. Affected file is
4042 lib/silcclient/command.c.
4044 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Fixed a fatal bug in private message sending and reception
4047 encryption and decryption when using private message keys.
4048 The implementation was incorrect and did not follow the
4049 specification. It causd that some of the message were
4050 lost since it did not use the sending and receiving keys
4051 as the protocol suggests. This has been fixed and will cause
4052 incompatibilities with older clients when sending private
4053 message encrypted with private message keys. Affected files
4054 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4055 and various other in Irssi SILC Client.
4057 Added `responder' boolean argument to the functions
4058 silc_client_add_private_message_key[_ske] to indicate when
4059 the key is added as responder or initiator of the key
4062 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4064 * Removed the silc_ske_check_version function and created
4065 a SilcSKECheckVersion callback. Added also a function
4066 silc_ske_set_callbacks that is now used to set all SKE
4067 callbacks. The callback functions are not given to
4068 the SKE functions anymore, but this function is used to
4071 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4073 * Added `silc_version' argument to the silc_client_alloc
4074 to define the version of the application for the library.
4075 The library will use the version string to compare it
4076 against the remote host's (usually a server) version
4077 string. Affected file lib/silcclient/silcapi.h
4079 * Added the KE protocol context to Key Agreement context
4080 in client library so that we can abort the SKE if it
4081 is in process when we get timeout. Affected file is
4082 lib/silcclient/client_keyagr.c.
4084 * Do not resolve the client ID forever if it returns in the
4085 first time that such client does not exist. This was done
4086 for example with private message. Affected file is
4087 lib/silcclient/client_prvmsg.c.
4089 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4091 * Do not add regex.h for WIN32. The affected file
4092 includes/silcincludes.h.
4094 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4095 not work yet 100%. It generates the DLL's automatically
4096 when compiling with --with-win32 under cygwin.
4098 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4100 * lib/contrib/regex.c is not compiled on WIN32.
4102 * Added silc_net_get_socket_opt function to the
4103 lib/silcutil/silcnet.h.
4105 * Added includes/silcwin32.h for WIN32 specific includes
4108 * Do not use ptime structure or any of the posix process
4109 functions on WIN32 in lib/silccrypt/silrng.c.
4111 * Added silc_gettimeofday to provide generic function
4112 for struct timeval on all platforms. Added the function
4113 to lib/silcutil/silcutil.h.
4115 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4117 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4118 library as they clearly belong there. As a plus side we
4119 can make the actual socket connection routines platform
4122 Added also new generic function silc_socket_read and
4123 silc_socket_write (that used to be silc_packet_[read/write].
4124 The implementation of these are platform specific.
4126 * Added WIN32 specific routines of silc_socket_[read/write]
4127 to lib/silcutil/win32/silcwin32sockconn.c.
4129 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4131 * Added preliminary support for native WIN32 compilation under
4132 cygwin (using the -mno-cygwin option for GCC) to the
4133 ./configure.in.pre. The --with-win32 now prepares the
4134 compilation for native WIN32.
4136 * Rewrote the SILC Scheduler interface in the file
4137 lib/silcutil/silcschedule.h. The scheduler is now context
4138 based and does not have anymore any global static scheduler.
4139 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4140 and created lib/silcutil/win32 directory for WIN32 based
4143 * Added Unix specific network routines to the
4144 lib/silcutil/unix/silcunixnet.c and the old
4145 lib/silcutil/silcnet.c includes now only generic routines.
4147 Added WIN32 specific network routines to the
4148 lib/silcutil/win32/silcwin32net.c.
4150 * Added Unix specific utility functions from the
4151 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4153 * Added WIN32 SILC Scheduler to the file
4154 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4157 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4159 * Do not handle JOIN notify in the server if the target client
4160 is not registered (idata->registered == FALSE). The affected
4161 file is silcd/packet_receive.c.
4163 * Update the nickrec->founder in event_cumode in the Irssi SILC
4164 client. Affected file irssi/src/silc/core/silc-channels.c.
4166 * Fixed the CUMODE_CHANGE notify handling in the server when
4167 server and router are announcing their clients on channels.
4168 Now the mode changes are saved and notified correctly. The
4169 affected file is /silcd/packet_receive.c.
4171 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4172 They really did not replace the cache entry in the ID Cache.
4173 Now they do that. Affected file silcd/idlist.c.
4175 * Fixed the KICK notify handling in the Irssi SILC client to
4176 update the channel records so that the kicked client does not
4177 appear to be on the channel. The affected file is
4178 irssi/src/silc/core/silc-channels.c.
4180 * Always update the conn->current_channel when executing command
4181 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4183 * Fixed the KILL notify handling in Irssi SILC client to remove
4184 the killed client on all channels.
4186 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4188 * Fixed the silc_parse_command_line to remove extra spaces
4189 from the start and end of the arguments. Affected file is
4190 lib/silcutil/silcutil.c.
4192 * Cancel and free any active protocol in the function
4193 silc_server_close_connection. Affected file silcd/server.c.
4195 * Cancel and free any active protocol in the function
4196 silc_client_close_connction. Affected file is
4197 lib/silcclient/client.c.
4199 * Do not execute the KILL command for clients that are in
4200 history (ie. they are not in the network). Affected file is
4203 * Fixed KILL notify handling, client does not crash anymore.
4204 Affected file irssi/src/silc/core/silc-channels.c.
4206 * Reduced the default packet buffer size from 2048 to 1024 in
4207 lib/silccore/silcpacket.c.
4209 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4210 counter to the SKE context that is incresed when the SKE library
4211 performs async operation outside the library. If the outside
4212 process frees the SKE context and FREED status will be set
4213 and the library will detect after the sync operation that the
4214 libary is freed. The affected files are
4215 lib/silcske/silcske[_status].[ch].
4217 * Resolve the client entry information in the function
4218 silc_client_channel_message to assure that NULL pointer is not
4219 passed as client entry to the application. */
4221 * Fixed the task timeout calculation to assure that there is
4222 never negative timeouts. The affected file is
4223 lib/silcutil/silcschedule.c.
4225 * Fixed the channel user mode notification sending in server.
4226 It was sent point-to-point to the router (or to server by router)
4227 but it needs to be destined to a channel. The routines now
4228 supports sending the channel user mode notifys to the channels
4229 when announcing clients and channels. Affected files are
4230 silcd/server.c and silcd/packet_receive.c.
4232 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4233 It did not actually replace the old channel entry in the cache.
4234 Affected file lib/silcclient/client_notify.c.
4236 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Fixed a possible crash in silc_packet_send_prepare. It now
4239 assures always that there is enough space in the buffer and
4240 at the tail area of the buffer (for MAC).
4242 Fixed the inbound buffer reallocation in silc_packet_read.
4243 It was old code and did not handle the reallocation correctly.
4246 The affected file is lib/silccore/silcpacket.c.
4248 * Fixed buffer overflow in silc_parse_nickname in the file
4249 lib/silcutil/silcutil.c.
4251 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * make install generates new server keys only if there is not
4256 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4259 Added check that if the NOREPLY is set then we will not send
4260 the away message. This avoids infinite loop of away messages
4261 if both clients are away. The affected file is
4262 lib/silcclient/client_prvmsg.c.
4264 * Fixed client crash if /NICK was given without arguments.
4265 Affected file lib/silcclient/command.c.
4267 * Server does not send the invite list in INVITE command back
4268 to the client if the list was not altered. Added this notion
4269 to the protocol spec as well. Affected file silcd/command.c.
4271 Fixed possible crash in INVITE command by checking the
4272 value of silc_server_get_client_route command.
4274 * Fixed the INVITE notify type handling. The arguments are now
4275 taken in correct order and client does not crash. The affected
4276 file is irssi/src/silc/core/silc-channels.c.
4278 Removed the "Inviting xxx to channel" message from the
4279 client library away and let the application handle it.
4280 Affected file lib/silcclient/command.c. Added that message
4281 to Irssi SILC client's message formats.
4283 * Fixed CMODE command crash in client. It now checks the
4284 amount of arguments correctly and does not crash. The affected
4285 file is lib/silcclient/command.c.
4287 * Do not create new channel automatically in silc_channels_join
4288 but check whether the channel by that name already exists.
4289 Affected file irssi/silc/core/silc-channels.c.
4291 * Do not send the SERVER_SIGNOFF to router if the disconnected
4292 entity was the router. Affected file silcd/server.c.
4294 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4295 SILC client as it was missing from there.
4297 Added the handling of the KICK notify to the Irssi SILC client
4298 as it was missing. Added "you have been kicked" message to
4299 Irssi SILC client's message modules formats.
4301 Added the handing of the KILL notify to the Irssi SILC client
4302 as it was missing. Added the kill message module formats
4305 The affected file is irssi/src/silc/core/silc-channels.c.
4307 * The router did not save the channel mode the server announced.
4308 Affected file silcd/packet_receive.c.
4310 * Fixed a possible crash in INFO command in server. If the
4311 server did not provide the server info it crashed. Affected
4312 file silcd/command.c.
4314 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Fixed the GETKEY command in the server to check also the
4317 global list. Otherwise the GETKEY would not work correctly
4318 in normal SILC server. Affected file silcd/command.c.
4320 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Fixed GETKEY crash, it crashed if the command did not succseed.
4324 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4327 is now real and not just an macro interface to GMP.
4329 Removed the entire GMP from the source tree and imported new
4330 NSS MPI library instead. Reason for removing GMP is that it is
4331 extremely large and compiles extremely slow. The NSS MPI
4332 is only a few files and compiles in less than 10 seconds.
4333 The speed is also about the same as GMP. The MPI is imported
4334 to lib/silcmath/mpi.
4336 If the system has GMP installed we will still use the GMP.
4337 If it is not then the NSS MPI will be compiled.
4339 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4341 * Merged a long nickname (127 characters long) crash bugfix from
4342 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4344 * Merged a freed memory reference bugfix from Irssi CVS tree.
4345 Affected file irssi/src/core/commands.c.
4347 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Added the server's public key sving and verification to the
4350 server when performing the SKE. This was missing and the
4351 remote server's (or router's) public key was accepted without
4352 checking whether we have it previously or trust it at all.
4353 Affected file silcd/protocol.c.
4355 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4357 * Check in the silc_server_timeout_remote if protocol is active
4358 and make sure that the protocol's final callback is called so
4359 that all memory if freed. Affected file silcd/server.c.
4361 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * silc_server_whois_send_reply crashed the server if the nickname
4364 was 127 characters long. Affected file silcd/command.c.
4366 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Added sanity check to the silc_server_new_client. If the hostname
4369 is provided inside username then check that the provided hostname
4370 really is the same as the resolved one. If the hostname was not
4371 resolved then check it from the public key. Affected file is
4372 silcd/packet_receive.c.
4374 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4375 if the server disconnected us and the connection is not valid
4376 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4378 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4379 the library to the lib/silcutil/silcutil.[ch].
4381 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4383 * Close log file after open. Affected file
4384 lib/silcutil/silclog.c.
4386 * Check whether sock == NULL in silc_client_send_packet and return
4387 if it is. Affected file lib/silcclient/silcclient.c.
4389 * Check rec->entry == NULL in the Irssi SILC Client before
4390 sending the channel message. Affecte file is
4391 irssi/src/silc/core/silc-servers.c.
4393 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Merged a splitted window bugfix from Irssi CVS tree. The
4396 affected file is irssi/src/fe-text/textbuffer-view.c.
4398 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4399 It did not print nickname.
4401 * Improved the distributions system a bit.
4403 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4406 irssi/src/fe-text/gui-window.c.
4408 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4409 to in-active server. The affected file is
4410 irssi/src/silc/core/client_ops.c.
4412 * Resolve the client in USERS command reply if the entry does
4413 not have username resolved. The affected file is
4414 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4415 command to WHOIS command to really resolve stuff. The USERS
4416 is not used any more in any critical section so WHOIS can
4417 be used even though it might be slower than IDENTIFY.
4419 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4422 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4424 * Changed the protocol API a bit more consistent in the
4425 lib/silccore/silcprotocol.[ch].
4427 * Changed the following headers to ROBODoc format:
4429 lib/silccore/silcpayload.h
4430 lib/silccore/silcprotocol.h
4431 lib/silccore/silcsockconn.h
4433 All core library headers are now formatted.
4435 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Fixed a bug in Irssi SILC client; do not show that you are
4438 server/router operator if you really are not. Affected file is
4439 irssi/src/silc/core/client_ops.c.
4441 * Renamed silc_command_free_payload to silc_command_payload_free.
4442 Affected file lib/silccore/silccommand.h
4444 * Added silcmath.h to include the prototoypes of various routines
4445 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4448 * Changed the following headers to ROBODoc format:
4450 lib/silccore/silcchannel.h
4451 lib/silccore/silccommand.h
4452 lib/silccore/silcid.h
4453 lib/silccore/silcidcache.h
4454 lib/silccore/silcmode.h
4455 lib/silccore/silcnotify.h
4456 lib/silccore/silcpacket.h
4457 lib/silcmath/silcmath.h
4459 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Added checking to the server code not to start the server if
4462 ciphers and stuff are not configured properly. Affected files
4463 silcd/serverconfig.[h] and silcd/server.c.
4465 * Changed the layout of the header files of the public interfaces
4466 in the SILC libraries. The new layout supports ROBODoc
4467 documentation tool (and some others) so that it is easy to create
4468 a library reference manual. All the other headers and source
4469 code must still follow the CodingStyle document. Also source
4470 code must not include these ROBODoc stuffs, only the headers.
4471 Furthermore, all public interface headers must now be named
4472 by using `silc' prefix, example: silcapi.h, silccipher.h.
4473 Some files were renamed due to this. All the other headers
4474 must not be used as public interfaces. I will update the
4475 CodingStyle document later. Changed following headers, so far:
4477 lib/silcclient/silcapi.h
4478 lib/silccore/silcauth.h
4479 lib/silccore/silcprivate.h
4480 lib/silccrypt/silcdh.h
4482 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Removed silc_client_packet_send_flush from the client library
4487 as it is not needed. Affected file lib/silcclient/client.[ch].
4489 * Added printing of message of unresolved authentication method
4490 to the Irssi SILC client. Added it to the module formats.
4491 Removed the same message from the client library.
4493 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Added new distribution feature, DISTLABEL. Every distribution
4496 can define own preprocessor label that can be used in the
4497 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4498 file distributions, acconfig.h.pre and prepare.
4500 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4502 * Added Makefile.defines_int to include the actual definitions
4503 for Makefile.defines.in. Tested the new distribution system,
4504 created distributions and tested installation.
4506 * Added AWAY message printing to the Irssi SILC client. Added
4507 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4509 * Added SCONNECT command to call the SILC's CONNECT command.
4510 Cannot use CONNECT directly since Irssi uses that internally.
4511 Affected file irssi/src/silc/core/silc-servers.c.
4513 Added ACTION local command. It is same as ME command but takes
4514 the channel as mandatory argument.
4516 Rewrote some of the Irssi's help files to suite for SILC
4519 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4521 * Added Makefile.defines[.in] that should for now on be included
4522 in all Makefile.am file in the source tree. That file includes
4523 all common compilation definitions for SILC source tree.
4525 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4527 * Minor changes to the ./prepare script to change the package
4528 name according the distribution name to the configure.in.
4530 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Created new distribution system. Added file `distributions'
4533 that defines all the distributions that can be created out of
4534 the SILC source tree. The ./prepare script now reads that
4535 file to determine how to prepare the distributions. The
4536 first argument to the ./prepare is the name of the distribution
4537 and second is the version of the distribution. If given
4538 without arguments it creates the default (toolkit) distribution
4539 with the default version (defined in ./prepare).
4541 All Makefile.am files that are subject to the distributions
4542 are now named as Makefile.am.pre. These are ./Makefile.am
4543 and lib/Makefile.am. Others may be changed later.
4545 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4547 * Added invite list, ban list, some key management and connection
4548 error message printing to module formats in the Irssi SILC client.
4550 * Added new silc_client_set_away_message to set the away message
4551 that is back to the person who sent private message. The
4552 affected file lib/silcclient/silcapi.h and the
4553 lib/silcclient/client_prvmsg.c.
4555 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4557 * Fixed the private message sending in the Irssi SILC client,
4558 added local command KEY to the Irssi SILC client.
4560 Added key management and key agreement message formats to the
4561 irssi/src/fe-common/silc/module-formats.[ch].
4563 Added USERS (alias WHO) printing, server/router operator
4564 indication and LIST command printing to the module formats.
4566 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4568 * Fixed channel joining notify handling, cumode notify handling
4569 from Irssi SILC client.
4571 * Added SILC specific module-formats to the Irssi SILC client so
4572 that SILC specific message hilighting, colors etc is possible.
4573 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4575 Added channel mode, channel user mode, actions, notices,
4576 whois and whowas printing to the the module-formats.c.
4578 * Fixed a bug in channel deletion in the server. The channel
4579 is not left to the cache even if the channel founder auth mode
4580 is set when there are no users anymore on the channel. Affected
4581 file silcd/server.c.
4583 * The silc_net_localhost now resolves the entire hostname including
4584 the domain name. Affected file lib/silcutil/silcnet.c.
4586 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * Changed the ask_passphrase client operation to be ascynchronous.
4589 It has now a completion callback and a context that the
4590 application must call after it has got the passphrase from
4591 the user. Affected files lib/silcclient/silcapi.h,
4592 lib/silcclient/protocol.c, lib/silcclient/command.c and
4595 Added SilcAskPassphrase callback that the application calls
4596 to deliver the passphrase to the library.
4598 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4599 The public key verification and especially a certificate
4600 verification is asynchronous procedure.
4602 Added new SILC_SKE_STATUS_PENDING status to indicate the
4603 request is pending and a callback will be called to finalize
4606 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4607 indicate that remote end did not send its public key (or
4608 certificate), even though we require it. Added check for this
4609 condition in the SKE. This was a security bug, now fixed.
4611 Defined new SilcSKEVerifyCbCompletion callback that is called
4612 when the verification process is completed.
4614 The affected files lib/silcske/silcske_status.h and
4615 lib/silcske/silcske.[ch].
4617 * Changed the verify_public_key client operation to be async
4618 as well. Defined SilcVerifyPublicKey callback that is used to
4619 indicate the success of the public key verification process.
4621 Changed the server and client to use the new async client
4624 * Changed the Irssi SILC client's internal scheduler to be called
4625 twice as many times as it used to be. As a result the client
4626 should be a bit faster now. Affected file is
4627 irssi/src/silc/core/silc-core.c.
4629 * Added support to Irssi SILC client of asynchronous public key
4630 verification and passphrase inquiry. Affected file is
4631 irssi/src/silc/core/silc-core.c.
4633 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Do not say "You have left channel %s" in client library.
4636 Moved it to the application. Affected files are
4637 lib/silcclient/command.c and silc/client_ops.c.
4639 * Fixed silc_client_get_clients. Command context was not
4640 duplicated and was freed memory in the callback. Affected
4641 file lib/silcclient/idlist.c.
4643 * Do not say "you are now talking..." on JOIN command in the
4644 client library. The appliation must handle it.
4646 * Do not say ".. changed topic to" in command reply in the
4647 client libary. The application must handle it.
4649 * Fixed TOPIC command sending in the client library.
4651 * Fixed a memory leak in silc_client_command_free in the file
4652 lib/silcclient/command.c.
4654 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Imported a modified version of Irssi client to the source tree.
4657 The Irssi will be used to create a new client called
4658 Irssi SILC. Imported to irssi/.
4660 Added silc_core_init_finish function to the Irssi. Affected
4661 file irssi/configure.in.
4663 A lot changes in the Makefile.ams around the irssi tree.
4665 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Do not rehash if the new size is same as the old size of the
4668 hash table, in the silc_hash_table_rehash*. The affected file
4669 lib/silcutil/silchashtable.c.
4671 * Replaced hash_table_del_by_context calls from the server
4672 (when channel->user_list and client->channels) to the
4673 hash_table_del as it is sufficient and faster.
4675 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4677 * Added silc_hash_table_list, silc_hash_table_get and the
4678 SilcHashTableList structure to provide an alternative way to
4679 traverse the hash table. The affected files are
4680 lib/silcutil/silchashtable.[ch].
4682 * Changed the server's idlist routines to use the hash table
4683 routines to optimize the code.
4685 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4687 * Replaced the client entry's `channel' list and channel entry's
4688 `user_list' list to hash tables for optimized lookup. Changed
4689 the code to use the hash table interface around the code.
4690 Affected file lib/silcd/idlist.[ch].
4692 * Added `auto_rehash' boolean argument to the function
4693 silc_hash_table_alloc to indicate whether the hash table should
4694 auto-rehash when it thinks is appropriate time. It will
4695 increase the hash table size if the there is twice as much
4696 entries in the table than the size of the table, and will
4697 decrease the size if there are twice as less entries than
4698 the size of the table.
4700 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4704 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * silc_idcache_purge_by_context deletes the entry now by context
4707 as it is supposed to do. Affected file lib/silccore/idcache.c.
4709 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4710 client is not anymore valid (WHOWAS givens the info) and not
4711 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4713 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Removed the `data' and `data_len' arguments from the ID Cache
4716 interfaces and added `name' argument. ID Cache does not handle
4717 anymore the binary data only a names associated with given ID.
4719 * When hashing a Client ID with silc_hash_id the entire ID is
4720 not hashed anymore, instead only the hash of the Client ID is
4721 hashed. This way we can access the Client ID from the cache
4722 with Client ID but with the hash of the ID (which is a hash of
4723 the nickname) as well without any difference in performance.
4725 Added also silc_idcache_find_by_id_one_ext to do one on one
4726 searching when we have the actual ID. Added also function
4727 silc_hash_client_id_compare. The affected files are
4728 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4730 * When hashing the name associated with a ID it is always done
4731 in lowercase. This way we can access the cache without worrying
4732 about case-sensitivity, even though, for example nicknames are
4735 * Fixed a bug in server with channel message sending. It put
4736 wrong ID type as destination ID. The affected file
4737 silcd/packet_send.c.
4739 * silc_idcache_del_by_context now deletes from all hash tables
4740 by context. Affected file lib/silccore/idcache.c.
4742 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4744 * Changed the client library to use the new ID Cache interface.
4745 Changes around the source tree.
4747 * Added silc_hash_table_rehash_ext to rehash with specific
4748 hash function. Affected file lib/silcutil/silchashtable.[ch].
4750 * Added silc_hash_string_compare to compare two strings in the
4751 hash table. Affected file lib/silcutil/silcutil.[ch].
4753 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4755 * Added new function silc_idcache_del_by_context into the
4756 lib/silccore/idcache.[ch].
4758 * Changed the server's ID list routines to use the new ID Cache
4759 interface. Changes around the source tree.
4761 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Added silc_hash_table_del[_by_context]_ext functions in to the
4764 lib/silcutil/silchashtable.[ch].
4766 Removed silc_hash_table_find_all* routines and added new
4767 silc_hash_table_find_foreach to replace them.
4769 Added silc_hash_table_replace_ext function as extended
4770 replacing function. Separated the simple hash table interface
4771 from the extended hash table interface in the file
4772 lib/silcutil/silchashtable.h.
4774 * Fixed minor bugs and changed it to use some of the new
4775 hash table functions in lib/silccore/idcache.c
4777 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4779 * Added new function silc_hash_table_find_all to return all keys
4780 in the hash table by the specified key. As the hash table is
4781 collision resistant it also makes it possible to have several
4782 duplicate keys in the hash table. This function may be used to
4783 find all of the keys from the hash.
4785 Added user_context arguments to the SilcHashFunction,
4786 SilcHashCompare and SilcHashDestructor to deliver user specified
4789 Added new fuctions silc_hash_table_find[_all]_ext to do
4790 extended lookup with specified hash and compare functions and
4791 specified user contexts.
4793 Added new function silc_hash_table_add_ext to add the key
4794 with specified hash function and user context.
4796 Added new function silc_hash_table_foreach to traverse all
4797 entrys in the hash table. Added SilcHashForeach callback
4800 Added new function silc_hash_table_del_by_context to delete
4801 the entry only if the context associated with the key matches.
4803 Affected files are lib/silcutil/silchashtable.[ch].
4805 * Removed silc_hash_[server/client/channel]_id and added just
4806 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4807 silc_hash_id_compare to compare two ID's using as the hash table
4808 comparison function. Added also silc_hash_data to hash
4809 binary data and silc_hash_data_compare to compare it.
4811 * Removed silc_idlist_find_client_by_hash as it is not needed
4812 anymore. Affected file silcd/idlist.[ch].
4814 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4815 to use internally the SilcHashTable. The new ID Cache is a lot
4816 faster than the old one. Some of the ID Cache interface was also
4817 rewritten and obsolete and stupid functions were removed.
4819 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4821 * Added entry_count field to the SilcHashTable to keep the number
4822 of the entries in the table. Implemented the function
4823 silc_hash_table_rehash. Added new function
4824 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4826 Fixed a minor bug in silc_hash_table_free.
4828 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4829 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4830 into the lib/silcutil/silcutil.[ch].
4832 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Implemented a collision resistant hash table into the
4835 lib/silcutil/silchashtable[ch]. See the header and the source
4836 for the SilcHashTable API.
4838 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Merged dotconf version 1.0.2 into lib/dotconf.
4842 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Do not compile anything in lib/silcsim/* if the SIM support
4845 is not enabled. The tree should now compile without problems
4848 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4850 * Compiled the SILC under cygwin. Compiled and tested briefly
4851 without problems. More tests needed. The SIMs didn't compile
4854 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4856 * Fixed possible crash in silc_get_username in the
4857 lib/silcutil/silcutil.c.
4859 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4861 * Fixed a va_arg in silc/client_ops.c.
4863 * Oops, RC5 routines were named AES and caused some problems
4864 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4866 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Added new SilcIDIP structure into the lib/silccore/id.h and
4869 replaced the old `ip' fields from all SILC ID's to that type.
4870 This is a step towards IPv6 support.
4872 The silc_id_get_len takes now the ID as an extra argument.
4873 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4874 both IPv4 and IPv6 based ID's.
4876 The affected files are lib/silccore/id.[ch] and other files
4877 around the tree using these routines.
4879 * Removed the ID length arguments in server from various
4880 silc_server_send_notify_* routines -> they are not needed
4883 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4885 * Fixed memory leak in silc_encode_pem_file in the file
4886 lib/silcutil/silcutil.c.
4888 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Check minor version as well in the SKE. Affected files are
4891 silcd/protocol.c and lib/silcclient/protocol.c.
4893 * Added --identifier option to the server so that an identifier
4894 can be when creating the public key for the server. Affected
4895 file is silcd/silcd.c.
4897 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4898 lib/silccrypt/silcpkcs.c.
4900 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Register default ciphers and stuff when using -C option with
4903 the server. Affected file sildc/silcd.c.
4905 * Put back the servers public key filename format, it is better
4906 than the new one. For now, the client keys are saved with the
4907 new filename format. The affected file silc/client_ops.c.
4909 * Implemented the Cipher API for the rest of the ciphers that
4910 did not implement it or implemented it the wrong way.
4912 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Register default ciphers and stuff when using the -S option
4915 in the client. Affected file silc/silc.c. Same also when
4916 creating new key pair with -C option.
4918 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4920 * Fixed the silc_verify_public_key client operation function to
4921 save the public keys differently. The fingerprint is now
4922 used as filename and not the hostname. This way also the
4923 client keys are saved uniquely and not with hostnames. The
4924 affected file is silc/client_ops.c.
4926 * Trimmed the silc_hash_fingerprint function to remove extra
4927 whitespaces from the end of the fingerprint. The affected
4928 file is lib/silccrypt/silchash.c.
4932 * Added silc_cipher_register_default function to register all
4933 default ciphers. It can be used when configuration files
4934 does not exist and the application does not want any specific
4935 ciphers in any specific order.
4937 The SilcDList is now used as silc_cipher_list dynamically
4938 allocated cipher list. Removed the static list all together
4939 and now all ciphers must be allocated to the dynamic list.
4940 The silc_cipher_alloc routine was changed to check only the
4943 All silc_cipher_* routines that used to return int returns
4946 The affected files lib/silccrypt/silccrypt.[ch].
4948 * The same thing was done to silc_hash_* as for silc_cipher_*
4949 routines. Affected files lib/silccrypt/silchash.[ch].
4951 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4952 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4953 Added also silc_pkcs_[un]register[_default] functions.
4954 Removed the data_context from the PKCS API.
4956 * Added silc_hmac_register_default function to register default
4957 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4958 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4959 to unregister all hmacs at once.
4961 * Register the default ciphers, hash functions, PKCSs and HMACs
4962 if client's configuration file does not exist. The affected
4965 * The client did not load the hash functions from the SIM
4966 modules at all. Added support for this. Affected file is
4967 silc/clientconfig.c.
4969 * When decoding public key with silc_pkcs_public_key_decode, check
4970 the supported algorithm only if PKCS are registered. Affected
4971 file lib/silccrypt/silcpkcs.c. The same was done with the
4972 silc_pkcs_private_key_decode.
4974 * Fixed the SILC List routines to keep the list always in order.
4975 It used to change the list's order when traversing the list but
4976 not it preserves the order. Affected file lib/trq/silclist.h.
4978 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Added the client library to use the SilcSocketConnection's
4981 reference counter (by silc_socket_dup) to prevent the bug that
4982 the socket object may be freed underneath async operation.
4984 * The name resolv library checking fixes in the configure.in.pre.
4987 * Created new version of the protocol drafts for future
4988 development. The -03 drafts are the ones that will be changed
4989 in the trunk now and the -02 will remain as they are.
4991 * Send list of CUMODE notifys to the router when announcing
4992 the channel users to the router. Affected file silcd/server.c.
4993 If the router receiving channel founder CUMODE for a channel
4994 that already has channel founder it will send CUMODE notify
4995 to the sender to remove the channel founder rights from the
4996 announced client. Affected file silcd/packet_receive.c.
4998 * The CUMODE notify may now use Server ID as well as the entity
4999 who changes the mode. Updated protocool specs.
5001 * Updated INSTALL and README files.
5003 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * New web pages in the http://silc.pspt.fi. The pages was
5010 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Implemented the [DenyConnectin] config section in the server.
5013 Added silc_server_config_denied_conn to check whether incoming
5014 connection is denied. Affected file silcd/serverconfig.[ch].
5016 * Do not check the ports when checking the incoming configuration
5017 data if the port is 0, meaning any. Affected file is
5018 silcd/serverconfig.c.
5020 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5022 * Fixed buffer overflow in silc_string_compare in the file
5023 lib/silcutil/silcutil.c.
5025 * Fixed double free in silc_server_command_leave in the file
5028 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Fixed the version checking in the server. Affected file is
5033 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5035 * Fixed the configuration data fetching when accepting new
5036 connections in the server. Affected file silcd/server.c.
5038 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Added `sender_entry' argument to the function
5041 silc_server_packet_relay_to_channel so that we can check
5042 whether some destination actually belongs to the same route
5043 the sender belongs (ie, we must not resend the packet to the
5044 sender). Affected file silcd/packet_send.[ch].
5046 * Added `servername' field to the SilcClientEntry in the server
5047 to hold the name of the server where client is from. Affected
5048 file is silcd/idlist.h.
5050 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Moved the channel message encrypting in the router betwen
5053 router connections from silc_server_channel_message to the
5054 silc_server_packet_relay_to_channel since we want to check
5055 whether we have anybody channel before encrypting anything.
5056 Affected files silcd/packet_[receive/send].c.
5058 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Fixed the [AdminConnection] server config section to support
5061 multiple entries. Affected file silcd/serverconfig.c.
5063 * Added support into the server to check the validity of the
5064 incoming connection before executing any KE or authentication
5067 * The connection configuration is now saved to the KE and
5068 connection auth protocol contexts and not fetched anymore in
5069 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5071 * The local hosts listenning address and port is also resolved
5072 now when starting the server. We want to have the socket object
5073 to include the real address and port for the listener. Added
5074 new function silc_net_check_local_by_sock into the files
5075 lib/silcutil/silcnet.[ch].
5077 * Fixed a broadcast bug in server -> do not broadcast if we
5080 * Fixed a routing bug. Do not route broadcast packets ever.
5081 Broadcast packets must be processed always and not routed since
5082 they may be destined to some other host than yourself and thus
5083 would get routed without no good reason. Affected file is
5086 * Added function silc_server_config_is_primary_route to check
5087 whether primary router connection has been configured (a router
5088 configuration that we are initiating). If there is not, we
5089 will assume that there is only two routers in the SILC network
5090 and we will use the incoming router connection as our primary
5091 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5093 * Changed the order of the broadcasting. Broadcast _after_ the
5094 packet has been processed not before. Affected file is
5097 * Fixed a [ClientConnection] parsing bug. The port was never
5098 parsed correctly thus resulting to port 0. Affected file
5099 silcd/serverconfig.c.
5101 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5102 argument and did not set the broadcast packet flag. Affected
5103 file silcd/packet_send.c. Fixed same bug in the function
5104 silc_server_send_notify as well.
5106 * If we receive NEW_ID packet for our own ID in the server, ignore
5109 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Removed the nickname from the Private Message Payload.
5114 Updated the code and the protocol specs.
5116 * Updated protocol specs for submitting to the IETF.
5118 * Tweaked the Random Number Generator a bit. Affected file
5119 lib/silccrypt/silcrng.c. Exported a new function
5120 silc_rng_[global]_add_noise which can be used to add more
5123 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Do not parse packets with different timeout when protocol
5126 is active -> may cause problem with rekey. Affected file
5129 * When server receives signoff notify it must not create
5130 new channel key if the client is on any channels since the
5131 sender of the signoff notify will create it.
5133 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added printing of error messages during SKE protocol from the
5136 failure packet sent by server during SKE. Affected file
5139 * Removed the client's failure_callback handling with timeout
5140 and handle it immediately when received.
5142 * The SKE library returned wrong type in SUCCESS and FAILURE
5143 packets. They must be 32 bit MSB not 16 bit MSB.
5145 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5147 * Ok, rewrote the logic of the re-key and now it seems to work.
5148 I tested it on high traffic with frequent re-keys without
5149 problems. Added hmac_receive (and renamed hmac to hmac_send)
5150 in SilcClientConnection in lib/silcclient/client.h and
5151 in SilcIDListData in silcd/idlist.h. Also, removed the
5152 SilcPacketParserContext's cipher and hmac fields as they are
5153 not needed anymore and actually caused some problems when
5154 the ciphers and hmac's changed underneath the packet parser.
5156 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * If re-key protocol is active then process the incoming packets
5159 synchronously since we must assure that icoming packets encrypted
5160 with the old key is processed before the new keys is set to
5161 use. This is true other packets than for REKEY packets.
5162 Affected file silcd/server.c. The same was done to client library
5163 as well, affected file lib/silcclient/client.c.
5165 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Fixed bug in client and server to accept the force send if
5168 the packet is send from silc_[server/client]_packet_process
5169 function. Otherwise the packets are never delivered, oops.
5171 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * Disable force sending of packets when REKEY protocol is active.
5174 We must assure that no packet is sent directly when rekey is
5175 performed. All packets must be sent through packet queue.
5176 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5177 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5178 function is silc_[server/client]_packet_send_real to check
5181 * Replaced the SIM paths from example config files to
5182 /usr/local/modules. Also, make install creates now
5183 /usr/local/silc/logs directory to hold all the SILC server
5186 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Made the configure.in.pre work on Solaris. Patch by salo.
5190 * Made all ciphers compatible with non-x86 machines. Defined
5191 CBC mode macros into lib/silccrypt/ciphers_def.h.
5193 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Fixed the make install.
5197 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5199 * When MAC computation fails the silc_packet_decrypt returned 0
5200 even though it was supposed to return -1. Fixed this. The
5201 affected file is lib/silccore/silcpacket.c.
5203 * Do not replace the config files in /etc/silc (in make install)
5204 if they already exist. Affected file ./Makefile.am.
5206 * Do not send re-key packets immediately but through packet queue.
5207 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5209 * Changed silc_net_check_host_by_sock to return FALSE if the
5210 IP/DNS could not be resolved. Though, it returns the IP address
5211 now even if it could not resolve it (but returns also FALSE).
5212 Affected file lib/silcutil/silcnet.[ch].
5214 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Added silc_pkcs_decode_identifier to decode the public key's
5217 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5218 Added also silc_pkcs_free_identifier. Added also new context
5219 SilcPublicKeyIdentifier.
5221 * Added -S option to the silc client. It is used to dump the
5222 contents of the specified public key file.
5224 * Changed the PKCS api to return the public key length when
5225 setting the public key.
5227 * Fixed a fatal bug in the public and private key file loading.
5228 Affected file lib/silccrypt/silcpkcs.c.
5230 * Execute the packet parsing for client with zero (0) timeout
5231 if the protocol is active. Affected file silcd/server.c.
5233 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Made the key generation options to the silcd program. Added
5236 -C option, equivalent to client's option.
5238 * Added new [ServerKeys] config section to the server. It
5239 configures the server's public and private key.
5241 * Defined generic Public Key Payload into the protocol
5242 specification to send specific type of public keys and
5245 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5246 public key or certificate.
5248 * Implemented the GETKEY command to the server and to the
5249 client library and on user interface.
5251 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5253 * Made preliminary `make install' work.
5255 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5257 * Added SilcServerRekey context into silcd/idlist.h.
5259 * Added the PFS support as defined in the specification to the
5260 SKE protocol. Affected files lib/silcske/*.c.
5262 * Added `ske_group' field to the SilcServerRekey context to hold
5263 the number of the SKE group that is used with PFS in re-key.
5264 Affected file silcd/idlist.h.
5266 * Added PFS re-key support to the server. Affected file is
5269 * Added silc_protocol_cancel to cancel execution of the next
5270 state of the protocol. Affected file is
5271 lib/silccore/silcprotocol.[ch].
5273 * Added the re-key support with and without PFS to the client
5274 library. Re-key is performed once in an hour, by default.
5276 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5277 Added silc_client_rekey_callback and silc_client_rekey_final.
5278 Affected files are lib/silcclient/protocol.[ch] and
5279 lib/silcclient/client.[ch].
5281 * Removed the `hmac_key' and `hmac_key_len' fields from the
5282 SilcClientConnection structure; not needed. Affected file is
5283 lib/silcclient/client.h.
5287 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5289 * Do not ask whether user wants to use the negotiated private key
5290 for private messages, just use it. Affected file is
5291 silc/local_command.c.
5293 * Added `send_enc_key' and `enc_key_len' fields to the
5294 SilcIDListData structure since they are needed in the re-key
5295 phase. Affected file is silcd/idlist.[ch].
5297 * Implemented the simple re-key protocol into the server.
5298 Affected files silcd/server.c and silcd/protocol.[ch]. The
5299 re-key will be performed once in an hour, by default.
5301 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5302 Added silc_server_rekey, silc_server_rekey_callback and
5303 silc_server_rekey_final.
5305 * Removed Tunneled flag from the protocol. Updated the code
5306 and the specifications.
5308 * Adde `pfs' field to the SilcIDListData to indicate whether
5309 the PFS is to be performed in the re-key. Affected file is
5312 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5315 int64 of at least the xintXX size. If void * is less that 4
5316 bytes uint32 * will be used. Defined bool as boolean.
5318 * Changed _ALL_ unsigned long and unsigned int to uint32,
5319 unsgined short to uint16 in the source tree.
5321 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5322 not handle clients that has entry->data.registered == FALSE.
5323 They are not in the network anymore. Affected file is
5326 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5328 * Implemented the sending of the SERVER_SIGNOFF notify in the
5329 server. Affected file is silcd/server.c.
5331 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5332 Added also silc_notify_payload_encode_args into the
5333 lib/silccore/silcnotify.[ch].
5335 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5336 Affected file silcd/packet_receive.c.
5338 * Implemented the SERVER_SIGNOFF notify handling in the client
5339 library. Affected file lib/silcclient/client_notify.c. Also,
5340 implemnted the printing of the SERVER_SIGNOFF info to the
5341 application. Affected file silc/client_ops.c.
5343 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5344 if the deleting was successful. Affected file silcd/idlist.[ch].
5346 * Added support for public key authentication in the connection
5347 authentication protocol in the client library. Affected file
5348 lib/silcclient/protocol.c.
5350 * Changed the server's silc_idlist_get_clients_by_* interface
5351 to support already allocated array so that new entries may be
5352 added to pre-allocated array. Affected file silcd/idlist.[ch].
5353 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5354 and command replies.
5356 * All command reply functions in the server now calls the
5357 pending command callback even if error occured. This way the
5358 error will be delivered to the client as well. Affected files
5359 silcd/command.c and silcd/command_reply.c.
5361 * Fixed INFO command to return local server's info if no server
5362 was provided. Affected file lib/silcclient/command.c.
5364 * Removed RESTART command for good. Updated the code and the
5367 * Rewrote parts of the task system. It is a bit simpler now.
5368 Removed unsued task priorities. The affected files are
5369 lib/silcutil/silctask.[ch].
5371 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5373 * Moved the USERS printing from the library to the application.
5374 Affected files lib/silcclient/command.c and silc/client_ops.c.
5376 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Added channel key re-key support. The re-key is perfomed
5381 only by the router and is done once in an hour. Added `rekey'
5382 field to the SilcChannelEntry in the server. Affected files
5383 silcd/server.c and silcd/idlist.h.
5385 * Added silc_task_unregister_by_context into the file
5386 lib/silcutil/silctask.[ch].
5388 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added SILC_UMODE_GONE mode to indicate when the client is not
5391 present in the SILC network. Added also support to the local
5392 command AWAY that will set this mode. Added support of showing
5393 "xxx is gone" in WHOIS command. The USERS command shows the
5394 gone status as well.
5396 * Fixed setting server and router operator privileges in the
5397 server's UMODE command. Affected file silcd/command.c.
5399 * Merged the SKE KE1 and KE2 payloads into one payload. The
5400 new KE payload is equivalent to the old KE2 payload.
5402 Cleaned up the SKE Start Payload parsing. It now uses the
5403 simple buffer unformatting to do the parsing. A lot faster
5406 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5407 to the SKE that is used to indicate whether both of the SKE
5408 parties should perform authentication. By default only the
5409 responder performs authentication. By setting this flag also
5410 the initiator must do authentication. By default it is unset
5411 since in normal SKE case, client to server connection, only
5412 the responder should do authentication. When doing SKE between
5413 two clients both should perform authentication. Updated the
5414 code and the protocol specs.
5416 * A little fix to IDENTIFY command in the server. Search the
5417 client first by hash not nickname. Affected file is
5420 * Fixed the silc_client_close_connection to support closing
5421 the client to client connections wihtout deleting too much
5422 data. Affected file lib/silcclient/client.c.
5424 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5425 are received if protocol used to be active but is not anymore
5426 the application would crash due to NULL pointer dereference.
5427 Affected files silcd/server.c and lib/silcclient/client.c.
5429 * Added `hash' field to the SilcClientConnection to include
5430 the hash function negotiated in the SKE protocol.
5432 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5433 to set the channel founder authentication data. A client can
5434 claim the founder rights later by providing the authentication
5435 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5436 This way the channel founder can regain the channel founder
5437 privileges even it is left the channel. This works only on
5438 local server and the client must be connected to the same
5439 server to be able to regain the founder rights. Updated the
5440 protocol specs accordingly.
5442 Added support to the CMODE command in the client to set the
5443 founder auth data. Read the README to see how to set it.
5445 Added support to the CUMODE command to claim the founder
5446 rights. Read the README to see how to do it.
5448 Added support for the founder authentication to the Channel
5449 Entry in the server. Affected file silcd/idlist.h.
5451 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5452 server's CMODE command. Affected file silcd/command.c.
5454 * Added the following new functions into lib/silccore/silcauth.[ch]:
5455 silc_auth_get_method and silc_auth_get_data.
5457 * The server now saves the remote hosts public key to the
5458 SilcIDListData pointer. Affected file silcd/protocol.c.
5460 * The normal server now does not remove the channel entry from
5461 the cache if the founder authentication data is set. It used
5462 to remove it if the founder was the last one on the channel on
5463 the server and left the channel. The auth data is saved and
5464 if the channel is re-joined later the old entry is used with
5465 the old auth data. Affected files silcd/command_reply.c and
5468 * Removed the `pkcs' field from the SilcIDListData structure
5469 in the server; it is not used. Affected file silcd/idlist.h.
5471 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Fixed packet processing on slow links. Partial packets were
5474 never re-processed because the incoming data buffer was cleared
5475 by the application. Application must not directly clear the
5476 sock->inbuf, the packet processing routines handle it. Fixed
5477 this in client library and in server.
5479 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5481 * Fixed the WHOIS and IDENTIFY send reply function to really
5482 check whether to send list or just one entry. Affected file
5485 * Cleaned up the LEAVE command's channel key distribution. The
5486 affected file silcd/command.c.
5488 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5489 can enforce the channel mode as well. In that case the ID
5490 includes the ID of the server. The code now enforces the
5491 mode change if the router have different mode than the server.
5493 * The notify client operation with CMODE_CHANGE notify can now
5494 return NULL client_entry pointer if the CMODE was not changed
5495 by client. Application must check for this.
5497 * Added <Server ID> argument to INFO command to support server
5498 info fetching by Server ID.
5500 * Added silc_server_announce_get_channel_users to get assembled
5501 packets of channel users of the specified channel. Affected
5502 file silcd/server.[ch].
5504 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5505 was freed underneath the ID Cache.
5507 * Re-announce clients when the server received CHANNEL_CHANGE
5508 notify from the router. Affected file silcd/packet_send.c.
5510 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5513 crashed since it did not handle the fact that there is no cipher
5514 called "3" and didn't check the error condition. Now fixed.
5516 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5517 flag. It can be used to send message requests.
5519 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Implemented the RESTART command in the client.
5523 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5524 notice type messages. Added notice printing to the user
5527 * The channel keys are not re-generated if the channel's mode
5528 is PRIVKEY, ie private key on the channel exists. Affected
5529 files silcd/server.c and silcd/command.c.
5531 * Fixed a little bug in channel message delivery when channel
5532 private keys are set in the server. Affected file is
5533 silcd/packet_send.c.
5535 * Changed the setting on channel->on_channel = TRUE from the
5536 silc_client_save_channel_key to the JOIN command reply. The
5537 key payload is not received if the private channel key is set.
5538 Affected file lib/silcclient/command_reply.c and the
5539 lib/silcclient/client_channel.c.
5541 * When the CMODE_CHANGE notify is sent and the channel private
5542 key mode is removed the channel key must be re-generated in
5543 other cells as well. Added this support for the router in the
5544 silcd/packet_receive.c.
5546 * Added new local command NOTICE to send notice message on
5547 channel. Affected file silc/local_command.[ch].
5549 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Added new local command ME to the client. It is used to send
5552 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5553 some action. Affected file silc/local_command.[ch].
5555 * Changed channel_message and private_message client operations
5556 to deliver the message flags to the application. Added also
5557 the `flags' arguments to the silc_client_send_channel_message
5558 and silc_client_send_private_message functions. Affected file
5561 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Redefined the Private Message Payload to support private message
5564 keys and to support the new private message flags. Updated
5565 the protocol specs. Flags makes it possible to have for example
5566 CTCP style messages.
5568 * Added new type SilcPrivateMessagePayload and defined an API
5569 for it in the lib/silcclient/silcprivate.[ch].
5571 * Tested private message private keys successfully. Tested the
5572 private message key set, unset and list commands with the new
5575 * Redefined the Channel Message Payload to include the channel
5576 message flags (equal with private message flags) to support
5577 for example CTCP style messages.
5579 * Defined some of the message (for channel and private message)
5580 flags. Updated the protocol specs and added the flags to the
5581 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5583 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * Added SilcKeyAgreementStatus type to the key agreement routines
5586 to indicate the current status and error if one occured.
5587 The status types are defined in the lib/silcclient/silcapi.h.
5589 * Added new local command KEY that is used to set and unset private
5590 keys for channels, set and unset private keys for private messages
5591 with remote clients and to send key agreement requests and
5592 negotiate the key agreement protocol with remote client. The
5593 key agreement is supported only to negotiate private message keys,
5594 it currently cannot be used to negotiate private keys for channels,
5595 as it is not convenient for that purpose.
5597 * Fixed a minor pending callback setting bug in the function
5598 silc_client_get_client_by_id_resolve, now the function works.
5599 Affected file lib/silcclient/idlist.c.
5601 * Added function silc_net_get_local_port to get local bound
5602 port by socket. Added to lib/silcutil/silcnet.[ch].
5604 * Added `sockets' and `sockets_count' fields to the SilcClient
5605 object. They hold the sockets of the listenning sockets in
5606 the client. Listenning sockets may be for example the key
5607 agreement server. Affected file lib/silcclient/client.[ch].
5608 Added functions the silc_client_add_socket and the
5609 silc_client_del_socket. They are exported to the application
5612 * Added ~./silc/clientkeys to support other client's public keys.
5614 * Renamed verify_server_key client operation to verify_public_key
5615 and added one argument to indicate the type of the connection
5616 (server, client etc.).
5618 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Added silc_server_connection_auth_request to handle the
5621 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5622 silcd/packet_receive.[ch].
5624 * Added silc_server_send_connection_auth_request into the
5625 silcd/packet_send.c to send the connection auth request packet.
5627 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5630 * Fixed the public key authentication in responder side in the
5631 server. The `auth_data' pointer includes the SilcPublicKey
5632 not the path to the public key. Affected file silcd/protocol.c.
5634 * Implemented the public key authentication in the initiator side
5635 in the server. Affected file silcd/protocol.c.
5637 * Removed the [RedirectClient] config section from the server
5638 configuration. Is not needed and I don't want to implement it.
5640 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Cleaned up the CMODE command in the server. It now works
5643 correctly and supports all the modes defined in the protocol.
5644 Affected file is silcd/command.c.
5646 * Added `hmac_name' field to the SilcChannelEntry in the server
5647 to hold the default HMAC of the channel. It can be set when
5648 creating the channel (with JOIN command). Affected files
5651 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5652 type to indicate the change of the current cipher and hmac
5653 on the channel. Client can safely ignore the <cipher> argument
5654 (if it chooses to do so) since the CHANNEL_KEY packet will
5655 force the channel key change anyway. The <hmac> argument is
5656 important since the client is responsible of setting the new
5657 HMAC and the hmac key into use.
5659 * Fixed the CMODE command in the client library as well.
5661 * Tested CMODE command in router environment successfully.
5663 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Show the version of the remote client (or server) when connecting
5666 to the server. It is logged to the log file. Affected file
5667 is silcd/protocol.c.
5669 * Fixed the KILLED notify handling in the client library. The
5670 client must be removed from all channels when receiving the
5673 Also, do not remove the client entry when giving the KILL
5674 command but when the KILLED notify is received.
5676 * Removed silc_idlist_find_client_by_nickname from the server.
5677 Not needed anymore. Affected files silcd/idlist.[ch].
5679 * Implemented the CHANNEL_CHANGE notify type handling to the
5680 server. Affected file silcd/server.c.
5684 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Added silc_server_send_notify_invite to send the INVITE
5687 notify between routers.
5689 * Implemented the INVITE command correctly to the server.
5691 * Implemented the INVITE notify type handling in the server.
5693 * Implemented the INVITE command to the client library and on the
5696 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Added function silc_server_get_client_resolve to find the
5699 client entry by ID from all ID lists and then resolve it
5700 (using WHOIS) if it cannot be found. Affected file is
5703 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Implemented the BAN command to the client library.
5707 * The JOIN command in the server now checks the invite list
5710 * Changed the silc_command_reply_payload_encode_va and the
5711 silc_command_payload_encode_va to support that if argument is
5712 NULL it ignores and checks the next argument. Affected file
5713 lib/silccore/silccommand.c.
5715 * Added silc_server_send_notify_ban to send the BAN notify
5716 type between routers.
5718 * Chaned the silc_notify_payload_encode to support that if
5719 argument is NULL it ignores and checks the next argument.
5720 Affected file lib/silccore/silcnotify.c.
5722 * Tested ban lists in router environment successfully.
5724 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Implemented BAN command to the server, in silcd/command.[ch].
5728 * Removed the BAN and INVITE_LIST modes from the CMODE command
5731 * Added function silc_string_match to regex match two strings.
5732 Affected files lib/silcutil/silcutil.[ch].
5734 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Redefined parts of the SilcChannelEntry in the server to support
5737 the new ban and invite lists.
5739 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Redefined the INVITE command. The same command can be used to
5742 invite individuals to the channel but also to manage the invite
5743 list of the channel (to add to and remove from the invite list).
5744 Updated the protocol specs.
5746 * Added new command SILC_COMMAND_BAN that can be used to manage
5747 the ban list of the channel. Updated the protocol specs.
5749 * Removed the channel modes: the SILC_CMODE_BAN and the
5750 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5751 in the CMODE command. The equivalent features are now available
5752 using INVITE and BAN commands. Updated the protocol specs.
5754 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5755 in the network about change in the current ban list. The notify
5756 type is not used by the client.
5758 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5759 support the invite lists.
5761 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Added new function silc_string_regexify that converts string
5764 including wildcard characters into regex string that can
5765 be used by the GNU regex library. Added into the file
5766 lib/silcutil/silcutil.[ch].
5768 Added silc_string_regex_combine to combine to regex strings
5769 into one so that they can be used as one regex string by
5770 the GNU regex library. Added into the file
5771 lib/silcutil/silcutil.[ch].
5773 Added silc_string_regex_match to match two strings. It returns
5774 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5776 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5778 * Imported GNU regex to the soruce tree into lib/contrib.
5779 Fixed some compiler warning from the regex.c.
5781 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Fixed MOTD command in the server to work in router environment.
5785 * Fixed the MOTD command in the client library to support
5786 the server argument in the command.
5788 * Added `nickname_len' argument to the silc_idlist_add_client
5789 in the server, as the `nickname' argument may be binary data
5792 * Added silc_idlist_get_channels to return all channels from
5795 * Implemented LIST command to the server. Affected file is
5798 * Implemented the LIST command to the client library and on the
5801 * Added [<user count>] argument to the LIST command reply.
5802 With private channels the user count is not shown.
5804 * Updated TODO and README.
5806 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * The client entry's data.registered must be TRUE even with
5809 global client entry on global client list. The data.registered
5810 is used to check whether the client is anymore in the network,
5811 for example with WHOWAS command so it must be valid.
5813 * Fixed the WHOWAS command in the server. It now actually works
5814 in router environment. Added function into silcd/command_reply.c
5815 silc_server_command_reply_whowas_save.
5817 * Added silc_idlist_purge function to the silcd/idlist.c
5818 to periodically purge the ID Cache.
5820 * Fixed INFO command in the server. It works now in router
5821 environment. Added <server name> argument to the INFO command
5822 reply. Updated the protocol specs.
5824 * Fixed minor bug in silc_idcache_purge to not purge if the
5825 expire value is zero.
5827 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5828 they were buggy because of the WHOWAS information.
5830 * Fixed local command MSG to handle the async resolving of
5831 the remote client properly. It used to fail the first MSG.
5832 Affected file silc/local_command.c.
5834 * Added `data_len' field to SilcIDCache context.
5836 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Update TODO. Todo in commands in the server.
5840 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5842 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5843 used by routers as broadcast packet to inform other routers
5844 about the changed user mode.
5846 Implemented the notify handling in the server. Affected file is
5847 silcd/packet_receive.c. Added the function
5848 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5850 * Added new generic Channel Payload and deprecated the New Channel
5851 Payload. The New Channel Payload is now the generic Channel
5854 * Added new argument `mode' to the silc_server_send_new_channel
5855 as it is required in the Channel Payload now.
5857 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5858 and created a new and real SilChannelPayload to represent the
5859 new generic Channel Payload. Implemented the encode/decode
5860 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5862 * Added silc_server_get_client_channel_list to return the list
5863 of channels the client has joined for WHOIS command reply.
5864 Affected file silcd/server.[ch].
5866 * Implemented the channel list sending in the WHOIS command reply
5867 in server and in the client.
5869 Implemented the channel list displaying on the user interface
5870 as well. Affected file silc/client_ops.c.
5872 * Added silc_channel_payload_parse_list to parse list of Channel
5873 Payloads. It returns SilcDList list of SilcChannelPayloads.
5874 Client for example can use this function to parse the list of
5875 channels it receives in the WHOIS command reply. The caller
5876 must free the list by calling silc_channel_payload_list_free.
5877 Affected files lib/silccore/silcchannel.[ch].
5879 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Added one new argument <user mode> to the WHOIS command reply
5882 to return the mode of the user in SILC. Updated the protocol
5885 Implemented it to the server and client.
5887 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Fixed the mode printing on the user interface on joining.
5890 Affected file silc/client_ops.c.
5892 * Implemented the UMODE command and user modes in general to the
5893 client library and to the user interface.
5895 * Implemented the UMODE command to the server.
5897 * The server now sends UNKNOWN_COMMAND error status if client sends
5898 unknown command. Affected file silcd/command.c.
5900 * All server commands now handle the command identifier the right
5901 way when sending the command reply to the client. The client can
5902 use to identify the command replies with the identifier.
5904 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5906 * Added silc_server_get_client_route to resolve the route to
5907 the client indicated by the client ID. Affected file is
5910 * Added silc_server_relay_packet as general function to relay
5911 packet to arbitrary destination. This deprecates functions
5912 like _send_private_message_key, _relay_notify etc. Affected
5913 file is silcd/packet_send.[ch].
5915 Removed silc_server_send_key_agreement,
5916 silc_server_send_private_message_key and
5917 silc_server_packet_relay_notify functions from the file
5918 silcd/packet_send.[ch].
5922 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5923 server. Affected file silcd/packet_receive.[ch].
5925 * Implemented the KILL command to the client. Implemented the
5926 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5927 Affected files lib/silcclient/command[_reply].c and
5928 lib/silcclient/client_notify.c. Implemented the KILL notify
5929 printing in the user inteface.
5931 * Fixed a lot silc_parse_nick memory leaks from the client
5932 library in the file lib/silcclient/command.c.
5934 * Changed the silc_server_send_notify_on_channels's `sender'
5935 argument from SilcSocketConnection to SilcClientEntry to
5936 check the sender as entry and not as connection object and not
5937 to send to the client provided as argument. The affected file
5938 is silcd/packet_send.[ch].
5940 * The notify packets that are destined directly to the client used
5941 to not to be processed by the server. Now changed that and the
5942 server processes all notify packets. After relaying the packet
5943 to the client the notify packet is processed in the server.
5945 * The silc_server_free_client_data now checks whether there is
5946 pending outgoing traffic for the client and purges the data to
5947 the network before removing the client entry.
5949 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5952 an client is killed from the SILC Network. Updated the protocol
5955 Added new function silc_server_send_notify_killed to the
5956 silcd/packet_send.[ch].
5958 * Added function silc_server_packet_relay_notify to relay notify
5959 packets that are destined directly to a client. In this case
5960 the server does not process the notify packets but merely relays
5961 it to the client. Affected file silcd/packet_send.[ch].
5963 Added also silc_server_packet_process_relay_notify to check
5964 whereto relay the notify. Affected file is
5965 silcd/packet_receive.[ch].
5967 * Implemented the KILL command to the server.
5971 * Added the backup schema desgined last fall to the protocol
5972 specs for everyone to see. The specification is in the
5973 *-spec-xx.txt draft and the packet type definitions for the
5974 backup routers is in *-pp-xx.txt draft. Thusly, added also
5975 new packet type SILC_PACKET_CELL_ROUTERS.
5977 * A big security problem in the implementation discovered. The
5978 signoff of an client did not cause new channel key generation
5979 which it of course should've done. The channel keys must be
5980 always re-generated when client leaves (or signoffs) the channel.
5981 The silc_server_remove_from_channels funtion now handles
5982 the channel key re-generation.
5984 * Added `sender' argument to the silc_server_send_notify_on_channels
5985 to not to send the client provided as argument. Affected file
5986 silcd/packet_send.[ch].
5988 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Implemented OPER and SILCOPER commands into the server and
5993 * Added silc_auth_verify and silc_auth_verify_data to verify
5994 the authentication directly from the authentication payload.
5995 It supports verifying both passphrase and public key based
5996 authentication. Affected file lib/silccore/silcauth.[ch].
5998 * Added `hash' field to the SilcIDListData structure. It is the
5999 hash negotiated in the SKE protocol. Affected file is
6002 * Slight redesigning of the SilcAuthPayload handling routines.
6003 Do not send SilcPKCS but SilcPublicKey as argument.
6005 * Implemented the public key authentication support to the
6006 serverconfig. The public key is loaded from the provided path
6007 and saved as authentication data to void * pointer. Thus,
6008 changed the unsigned char *auth_data to void *auth_data;
6010 * Fixed SHUTDOWN command to send the reply before the server
6011 is shutdown. :) Affected file silcd/command.c.
6013 * Fixed fatal bug in CONNECT command. The hostname was invalid
6014 memory and server crashed. Affected file silcd/command.c.
6016 * Fixed fatal bug in CLOSE command. The server_entry became
6017 invalid but was referenced later in the command. Affected file
6020 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Fixed fatal bug in failure packet handling. Server ignored
6023 the failure and thus crashed when it came.
6027 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6030 that the command may be executed only once in (about) 2 seconds.
6031 The old SILC_CF_LAG flag is same but allows command bursts up
6032 to five before limiting.
6034 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6035 server code. Various commands now includes the CF_LAG_STRICT
6036 flag to disallow any kind of miss-use of the command.
6038 * Fixed the silc_buffer_unformat to not to allocate any data
6039 if the length of the data is zero. It used to allocate the
6040 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6042 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Changed the format of AdminConnection configuration section
6045 in the server. Added username of the admin to the format.
6046 Affected files silcd/serverconfig.[ch].
6048 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6049 to return admin configuration data by host, username and/or
6052 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Implemented WHOWAS command to the server. Added the functions:
6056 silc_server_command_whowas_parse,
6057 silc_server_command_whowas_send_reply,
6058 silc_server_command_whowas_from_client and
6059 silc_server_command_whowas_from_server
6061 * Added <Client ID> argument to the WHOWAS command reply. Updated
6062 the protocol specs accordingly.
6064 * Implemented WHOWAS command and command_reply to the client
6067 Implemented the WHOWAS printing on the user interface.
6069 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6071 * Added new argument to the WHOWAS command reply, the real name.
6072 It is an optional argument. Updated the protocol specs.
6074 * Added SilcIDCacheDestructor callback that is registered when
6075 the SilcIDCache is allocated. The callback is called when
6076 an cache entry in the ID Cache expires, or is purged from the
6077 cache. Added into lib/silccore/idcache.[ch].
6079 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6080 to destruct the client entries when the cache entry expires.
6081 Other ID Cache's in server and in the client library ignores
6084 * If the ID Cache entry's `expire' field is zero then the entry
6085 never expires. Added boolean `expire' argument to the
6086 silc_idcache_add function in the lib/silccore/idcache.[ch].
6087 If it is TRUE the default expiry value is used.
6089 * Added silc_server_free_client_data_timeout that is registered
6090 when client disconnects. By default for 5 minutes we preserve
6091 the client entry for history - for WHOWAS command.
6093 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added support to the server to enforce that commands are not
6096 executed more than once in 2 seconds. If server receives
6097 commands from client more frequently, timeout is registered
6098 to process the commands. Affected file silcd/command.c.
6099 Added new function silc_server_command_process_timeout.
6101 * Changed NICK_NOTIFY handling in client library to check that
6102 if the client's nickname was changed, so there is no need to
6103 resolve anything from the server.
6105 * Removed error printing from the WHOIS and IDENTIFY commands.
6106 If error occurs then it is ignored silently in the client library.
6107 The application, however, may map the received error to
6108 human readable error string. The application currently maps
6109 the NO_SUCH_NICKNAME error to string.
6111 * Made the command status message public to the application. Moved
6112 them from lib/silcclient/command_reply.c to
6113 lib/silcclient/command_reply.h. The application can map the
6114 received command status to the string with the
6115 silc_client_command_status_message function.
6117 * Added check to the server to check that client's ID is same
6118 as the Source ID in the packet the client sent. They must
6121 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Added dist-bzip hook to the Makefile.am to make bzip2
6124 compressed distributions.
6126 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6128 * Server now enforces the maximum length for the nickname and
6129 the channel as protocol specification dictates. 128 bytes for
6130 nickname and 256 bytes for channel name.
6132 * Moved the WHOIS printing to the application. The client libary
6133 does not print out the WHOIS information anymore, the application
6134 must do it. Renamed silc_client_command_reply_whois_print to
6135 the silc_client_command_reply_whois_save.
6137 The client's idle time is also sent to the application now, and
6138 the idle is shown on screen.
6140 * Added silc_client_command_reply_identify_save to save the
6141 received IDENTIFY entries.
6143 * Do not check for channel private keys in message sending and
6144 reception if the channel does not have the PRIVKEY mode set.
6145 Affected file lib/silclient/client_channel.c.
6147 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6149 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6150 just surfaced after chaning the JOIN procedure.
6152 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6154 * Added silc_client_get_clients_by_list to get client entries
6155 from Client ID list, that is returned for example by JOIN
6156 and USERS command replies. The application should use this
6157 function for example when JOIN command reply is received to
6158 resolve the clients already on the channel (library does not
6159 do that anymore as USERS command reply is not used in the JOIN
6160 procedure anymore). Affected files lib/silcclient/silcapi.h and
6161 lib/silcclient/idlist.c.
6163 * JOIN command reply and USERS command reply returns now SilcBuffer
6164 pointers instead of unsigned char pointers when returning
6165 the client list and mode list.
6167 * Added <Client ID> argument to the JOIN command reply, mainly
6168 for the server to identify for which client the command was
6169 originally sent. Updated protocol specs accordingly.
6171 * Added SilcDlist private_key pointer to the SilcChannelEntry
6172 in the client to support the channel private keys. Affected
6173 file is lib/silcclient/idlist.h.
6175 * Added SilcChannelPrivateKey argument to the function
6176 silc_client_send_channel_message so that application can choose
6177 to use specific private ke if it wants to. If it is not provided,
6178 the normal channel key is used, unless private keys are set.
6179 In this case the first (key that was added first) is used
6180 as the encryption key.
6182 * Implemented the support for channel private key handling.
6183 Implemented the following functions:
6185 silc_client_add_channel_private_key,
6186 silc_client_del_channel_private_keys,
6187 silc_client_del_channel_private_key,
6188 silc_client_list_channel_private_keys and
6189 silc_client_free_channel_private_keys
6191 Affected file lib/silcclient/client_channel.c.
6193 * Added the support for the private keys in the channel message
6194 sending and encryption and in the message reception and
6195 decryption. Affected funtions are
6196 silc_client_send_channel_message and silc_client_channel_message.
6198 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6200 * Added SKE's key verify callback to the client library's
6201 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6203 * Removed the statement that server (or router) must send USERS
6204 command reply when joining to the channel so that the client
6205 knows who are on the channel. Instead, the client list and
6206 client's mode list is now sent in the JOIN command reply to the
6207 client who joined channel. This is better solution.
6209 * Added function silc_server_get_users_on_channel and function
6210 silc_server_save_users_on_channel to the silcd/server.[ch].
6212 * Removed function silc_server_command_send_users from the
6215 * Do not show topic on the client library anymore. The topic is
6216 sent in the command reply notify to the application and the
6217 application must show the topic now.
6219 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Added client searching by nickname hash into the IDENTIFY and
6222 WHOIS commands in the server as they were clearly missing from
6223 them. Affected file is silcd/command.c.
6225 * Fixed a bug in private message receiving in the client library.
6226 The remote ID was freed and it wasn't supposed, now it is
6229 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6231 * Minor fix to the channel payload; allocate the data area, as it
6232 needs to be of specific length.
6234 * If the key agreement port is zero then the operating
6235 system will define the bound port. Affected files are
6236 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6238 * Added new function silc_channel_payload_decrypt into the file
6239 lib/silccore/silcchannel.[ch].
6241 * Moved the channel message etc, check from silc_packet_decrypt
6242 to applications. The library calls now a generic
6243 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6244 when the packet is either normal or special. This was done to
6245 allow more wide range of checking that was not allowed when
6246 the code was in library. Now applications can do virtually any
6247 checks to the packet and return to the library the decision how
6248 the packet should be processed. Affected files are
6249 lib/silccore/silcpacket.[ch].
6251 Added silc_server_packet_decrypt_check to the server and
6252 silc_client_packet_decrypt_check to the client library.
6254 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6255 to send with specified source and destination information.
6257 * Channel message delivery between routers was broken after the
6258 channel key distribution was fixed earlier. The channel key
6259 was used be to distributed to other routers as well which is not
6260 allowed by the protocol. Now this is fixed and channel keys
6261 really are cell specific and the channel message delivery between
6262 routers comply with the protocol specification.
6264 * Fixed various commands in server to check also the global list
6265 for the channel entry and not just the local list. The affected
6266 file silcd/command.c.
6268 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * Added assert()s to buffer formatting and unformatting routines
6271 to assert (if --enable-debug) when error occurs. Affected
6272 file: lib/silcutil/silcbuffmt.c.
6274 * Changed to auto-reconnect to check whether the remote host is
6275 router and register the re-connect timeout if it is. It used
6276 to check that whether we are normal server, but router must do
6277 auto-reconnect with another router as well. Affected file
6280 * Removed the [<key len>] option from CMODE command as the cipher
6281 name decides the key length, nowadays. See the defined ciphers
6282 from the protocol specification.
6284 * Added [<hmac>] option to the CMODE command to define the HMAC
6285 for the channel. Added SILC_CMODE_HMAC channel mode.
6287 * Added [<hmac>] option for the JOIN command so that user can
6288 select which HMAC is used to compute the MACs of the channel
6291 * Added Hmac field to the Channel Message Payload. The integrity
6292 of plaintext channel messages are now protected by computing
6293 MAC of the message and attaching the MAC to the payload. The
6294 MAC is encrypted. Now, it is clear that this causes some
6295 overhead to the size of the packet but rationale for this is that
6296 now the receiver can verify whether the channel message decrypted
6297 correctly and also when private keys are set for the channel the
6298 receiver can decrypt the packet with several keys and check from
6299 the MAC which key decrypted the message correctly.
6301 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6302 lib/silccrypt/silccipher.[ch].
6304 * Added silc_hash_len to return the digest length into the
6305 lib/silcrypt/silchash.[ch].
6307 * Rewrote parts of Silc Channel Payload interface in the
6308 lib/silccore/silcchannel.[ch]. The encode function now also
6309 encrypts the packet and parse function decrypts it.
6311 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Fixed a minor formatting bug in the SKE's key material processing.
6314 It actually might have processed the keys wrong way resulting
6317 * Redefined the mandatory HMAC algorithms and added new algorithms.
6318 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6319 and hmac-md5 truncated to 96 bits. The mandatory is now
6320 hmac-sha1-96. Rest are optional (including the one that used
6321 to be mandatory). Rationale for this is that the truncated HMAC
6322 length is sufficient from security point of view and can actually
6323 make the attack against the HMAC harder. Also, the truncated
6324 HMAC causes less overhead to the packets. See the RFC2104 for
6327 * Added new [hmac] configuration section. The SKE used to use
6328 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6329 is of course wrong. The official names that must be proposed in
6330 the SKE are the ones defined in the protocol specification
6331 (hmac-sha1-96 for example). The user can configure any hmac
6332 using any hash function configured in the [hash] section. At
6333 least, the mandatory must be configured.
6335 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6337 * Added HMAC list to the SKE proposal list. It has now both
6338 hash algorithm list and HMAC list. This makes the protocol
6339 incompatible with previous versions. The SKE now seems to work
6340 the way it is supposed to work, for the first time actually.
6342 * Defined plain Hash algorithms to the protocol specification.
6345 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Implemented support for key agreement packets into the server.
6348 Added functions silc_server_key_agreement and
6349 silc_server_send_key_agreement. Other than these functions,
6350 server has nothing to do with this packet.
6352 * Added support for private message key packets into the server.
6353 Added functions silc_server_private_message_key and
6354 silc_server_send_private_message_key.
6358 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6359 called in the protocol's final callback instead in the END
6360 protocol state. This makes a little more sense and in the same
6361 time in client we can use the same protocol routines for normal
6362 key exchange and to key agreement packet handling as well.
6364 * Added to both client's and server's KE protocol context the
6365 SilcSKEKeyMaterial pointer to save the key material. We will
6366 bring the key material to the protocol's final callback by doing
6367 this. The final callback must free the key material.
6369 * Added SKE's packet_send callback into client's KE protocol
6370 context so that the caller can choose what packet sending function
6371 is used. This way we can use different packet sending when
6372 doing normal SKE when doing key agreement packet handling (in
6373 the key agreement packet handling we do not want to encrypt
6376 * Implemented the responder side of the key agreement routines
6377 in the client. The client can now bind to specified port and
6378 accept incoming key negotiation. The key material is passed
6379 to the application after the protocol is over.
6381 * Implemented the processing of incoming Key Agreement packet
6382 in the client. Added function silc_client_key_agreement to
6385 * Implemented the intiator side of the key agreement routines
6386 in the client. The client can now initiate key agreement with
6387 another remote client. The key material is passed to the
6388 application after the protocol is over.
6390 * Created client_keyagr.c to include all the key agreement
6393 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6394 SILC_TASK_CALLBACK except that it is not static.
6396 * Created client_notify.c and moved the Notify packet handling
6397 from the client.[ch] into that file.
6399 * Created client_prvmsg.c and moved all private message and
6400 private message key routines from the client.[ch] into that file.
6402 * Create client_channel.c and moved all channel message and
6403 channel private key routines from the client.[ch] into that file.
6405 * Changed silc_client_get_client_by_id_resolve to resolve with
6406 WHOIS command instead of IDENTIFY command, in the file
6407 lib/silclient/idlist.c.
6409 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6411 * Implemented the SKE's responder side to the Client library.
6413 * When FAILURE is received to the protocol do not trust it
6414 blindly. Register a timeout to wait whether the remote closes
6415 the connection as it should do it, only after that process the
6416 actual failure. This was changed to both client and server.
6418 * Added client_internal.h to include some of the structures
6419 there instead of client.h in lib/silcclient/.
6421 * Added function silc_task_unregister_by_callback to unregister
6422 timeouts by the callback function.
6424 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Some "Incomplete WHOIS info" errors has been appearing on the
6427 log files. Took away the entry->userinfo check from WHOIS
6428 reply sending. The entry->userinfo is now " " if client did not
6429 provide one. I thought this was fixed earlier but something
6430 is wrong still. Let's see if the error still appears.
6432 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Fixed a minor bug in the login when the channel key is
6435 re-generated in the server. It used to generate the key in
6436 wrong order and thus caused problems in the channel traffic.
6438 * Fixed a minor bug in channel key distsribution after
6439 KICK command. The key was not sent to the router even though
6442 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Added silc_ske_process_key_material_data as generic routine
6445 to process any key material as the SILC protocol dictates. The
6446 function is used by the actual SKE library but can be used by
6447 applications as well. This relates to the private message keys
6448 and the channel private keys since they must be processed the
6449 same way the normal SILC session keys. The protocol dictates
6450 this. Affected files: lib/silcske/silcske.[ch].
6452 Added also silc_ske_free_key_material to free the
6453 SilcSKEKeyMaterial structure.
6455 * Defined silc_cipher_set_key function to set the key for
6456 cipher without using the object's method function. The affected
6457 files: lib/silccrypt/silccipher.[ch].
6459 * Implemented silc silc_client_add_private_message_key,
6460 silc_client_add_private_message_key_ske,
6461 silc_client_del_private_message_key,
6462 silc_client_list_private_message_keys and
6463 silc_client_free_private_message_keys functions in the
6466 Added functions silc_client_send_private_message_key to send
6467 the Private Message Key payload and silc_client_private_message_key
6468 to handle incoming Private Message Key payload.
6470 * Added Cipher field to the Private Message Key payload to set
6471 the cipher to be used. If ignored, the default cipher defined
6472 in the SILC protocol (aes-256-cbc) is used.
6474 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Removed lib/silcclient/ops.h file.
6478 Redefined parts of the SILC Client Library API. Created new
6479 file silcapi.h that deprecates the ops.h file and defines the
6480 published Client Library API. Defined also private message key
6481 API and channel private key API into the file.
6483 This is the file that the application must include from the
6484 SILC Client Library. Other files need not be included by
6485 the application anymore.
6487 * Added new key_agreement client operation callback and also
6488 defined the Key Agreement library API for the application.
6490 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6493 is used by clients to request key negotiation between another
6494 client in the SILC network. If the negotiation is started it
6495 is performed using the SKE protocol. The result of the
6496 negotiation, the secret key material, can be used for example
6497 as private message key.
6499 Implemented the Key Agreement payload into the files
6500 lib/silccore/silauth.[ch].
6502 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6504 * Redefined ciphers for the SILC protocol. Added some new ciphers
6505 and defined the key lengths for the algorithms. Changed the
6506 code accordingly. The default key length is now 256 bits.
6508 * Fixed SKE key distribution function silc_ske_process_key_material
6509 when the key length is more than 128 bits. The default key
6510 length in SILC is now 256 bits.
6512 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6513 to indicate unsupported algorithm.
6515 * Renamed rijndael.c to aes.c and all functions as well.
6517 * Fixed a long standing channel key setting bug in client library.
6518 Weird that it has never surfaced before.
6520 * Fixed bug in channel deletion. If the entire channel is removed
6521 then it must also delete the references of the channel entry
6522 from the client's channel list as the client's channel entry and
6523 the channel's client entry share same memory.
6525 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Implemented CONNECT and SHUTDOWN commands in the client.
6529 * Implemented CLOSE command to the client.
6531 * Added the function silc_idlist_find_server_by_name into the
6532 files silcd/idlist.[ch].
6534 Added the function silc_idlist_find_server_by_conn into the
6535 files silcd/idlist.[ch].
6537 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6539 * DIE command was renamed to SHUTDOWN. Updated the both code
6542 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6543 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6545 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6548 * Added function silc_server_create_connection function to create
6549 connection to remote router. My server implementation actually
6550 does not allow router to connect to normal server (it expects
6551 that normal server always initiates the connection to the router)
6552 so the CONNECT command is only good for connecting to another
6555 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6558 or some other client was kicked from the channel.
6560 Implemented the handling of the notify type to both client
6563 Implemented silc_server_send_notify_kicked to send the KICKED
6564 notify. It is used to send it to the server's primary router.
6566 * Implemented the KICK command into server and client.
6568 * Added `query' argument to the silc_idlist_get_client function
6569 to indicate whether to query the client from server or not if
6572 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6573 to indicate that the client is not channel founder.
6577 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Removed the rng context from SilcPacketContext structure and
6580 changed that the packet routine uses the Global RNG API.
6582 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Added support for quit message that client can "leave" on the
6585 channel when it quits the SILC. It is ditributed inside the
6586 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6588 Added silc_server_free_client_data that will take the
6589 signoff message as argument.
6591 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6593 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Updated parts of the protocol specification to keep it up
6598 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6600 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6601 payloads in one packet.
6603 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6604 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6605 use now the new List flag.
6607 * Also deprecated the following packet types: REPLACE_ID,
6608 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6610 * Added list support for Notify packet in server.
6612 * Added silc_server_send_notify_channel_change to send the
6613 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6614 the silc_server_send_replace_id.
6616 * Added silc_server_send_notify_nick_change to send the
6617 NICK_CHANGE notify type. Deprecates the function
6618 silc_server_send_replace_id.
6620 * Added silc_server_send_notify_join to send the JOIN notify type.
6621 Deprecates the function silc_server_send_new_channel_user.
6623 * Added silc_server_send_notify_leave to send LEAVE notify type.
6624 Deprecates the function silc_server_send_remove_channel_user.
6626 * Added silc_server_send_notify_cmode and
6627 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6628 types. Deprecates the silc_server_send_set_mode function.
6630 * Added SERVER_SIGNOFF notify type to indicate that server has
6631 quit. This means that all clients on the channel from that
6632 server will drop. This can be also used when netsplit happens.
6634 Deprecated REMOVE_ID packet type since it is not needed anymore
6637 Added silc_server_send_notify_server_signoff to send the
6638 SERVER_SIGNOFF notify type. Deprecates the function
6639 silc_server_send_remove_id.
6641 Added also silc_server_send_notify_signoff to send the
6642 SIGNOFF notify type.
6644 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6645 SILC protocol from this day on. Changed the protocol
6646 specification as well.
6648 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6649 notify type. It is used between routers to notify about
6650 topic changes on a channel.
6652 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6655 * Partly updated the protocol specification to comply with the
6656 changes now made. It is still though a bit outdated.
6658 * The JOIN notify type now takes one extra argument <Channel ID>.
6659 The packet used to be destined to the channel but now the
6660 JOIN type may be sent as list thus it is impossible to
6661 destine it to any specific channel. By adding this argument
6662 it is again possible.
6664 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Added CREDITS file. The CHANGES and CREDITS file will appear
6667 in the distribution as well.
6669 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6672 types in the server's silcd/packet_receive.c.
6674 * Implemented CMODE and CUMODE to work in router environment.
6676 * Fixed minor encoding and decoding buglet from the
6677 lib/silccore/silcmode.c.
6679 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6682 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6684 * Changed all SilcConfigServer* and silc_config_server* to
6685 SilcServerConfig* and silc_server_config*, respectively.
6688 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6690 * Associated the ID (client or server ID) to the Authentication
6691 Payload to avoid any possibility of forging. Updated the
6692 protocol specification and the code accordingly.
6694 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6696 * The RSA key length is now save to the RsaKey context in the
6697 key generation process in lib/silccrypt/rsa.c. The key length
6698 is now used to figure out the maximum size of the block allowed
6699 to be encrypted/signed.
6701 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6702 is equivalent to the silc_mp_mp2bin but does not allocate any
6705 * Changed silc_mp_mp2bin API to take length argument. If it is
6706 non-zero then the buffer is allocated that large. If zero, then
6707 the size is approximated using silc_mp_sizeinbase, which however
6710 * Created Global RNG API which is global RNG that application can
6711 initialize. After initializing, any routine anywhere in the
6712 code (including library) can use RNG without allocating a new
6713 RNG object. This was done to allow this sort of use of the
6714 RNG in code that has no chance to allocate RNG object. All
6715 applications currently allocate this and many routines in the
6716 library use this. Affected file lib/silccrypt/silcrng.[ch].
6718 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6719 it to use the Global RNG API.
6721 * Defined Authentication Payload into protocol specification that
6722 is used during SILC session to authenticate entities. It is
6723 used for example by client to authenticate itself to the server
6724 to obtain server operator privileges.
6726 Implemented this payload into the lib/silccore/silcauth.[ch].
6727 Implemented also routines for public key based authentication
6728 as the new protocol specification dictates.
6730 Moved definitions of different authentication methods from
6731 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6733 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6734 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6735 silc_pkcs_verify_with_hash functions into the file
6736 lib/silccrypt/silcpkcs.[ch].
6738 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6740 * The client entry's userinfo pointer must be always valid.
6741 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6742 will fail since it requires the userinfo. Now, the userinfo
6743 is allocated as "" if actual userinfo does not exist. Actually,
6744 it must exist and it is totally Ok to drop client connections
6745 that does not announce the userinfo. However, we will make
6746 this workaround for now.
6748 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6749 to return the remote port by socket.
6751 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6754 SILC_SERVER_PENDING_EXEC and added an new macro
6755 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6756 data or when error occurs while processing the pending command.
6758 Added new argument `destructor' into silc_server_command_pending
6759 and to the SilcServerCommandPending object. This destructor is
6760 now called after calling the pending callback or if error occurs
6761 immediately. If error occurs the actual pending callback won't
6762 be called at all - only the destructor. The destructor may be
6763 NULL if destructor is not needed.
6765 All this applies for client library code as well. Similar
6766 changes were made there as well for the pending commands.
6768 In the client, the application must now allocate the
6769 SilcClientCommandContext with the silc_client_command_alloc
6772 * Added reference counter to the SilcServerCommandContext. Added
6773 function silc_server_command_alloc and silc_server_command_dup
6776 Same type of functions added to the client library for the same
6779 * Removed the cmd_ident from IDListData away since it is now
6780 global for all connections. It is the command identifier used
6781 in command sending and with pending commands. The affected file
6784 * Added reference counter to the SilcSocketConnection objecet to
6785 indicate the usage count of the object. The object won't be
6786 freed untill the reference counter hits zero. Currently only
6787 server uses this, and client ignores it. The client must be
6788 set to use this too later. The affected files are
6789 lib/silccore/silcsockconn.[ch]. Added also the function
6790 silc_socket_dup to increase the reference counter.
6792 This was mainly added because it is possible that the socket
6793 is removed underneath of pending command or other async
6794 operation. Now it won't be free'd and proper DISCONNECTING
6795 flags, etc. can be set to avoid sending data to connection that
6796 is not valid anymore.
6798 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6799 the connection. After that it sets SILC_SET_DISCONNECTED.
6800 It is, however, possible that the socket data is not still freed.
6801 The silc_server_packet_process now checks that data is not
6802 read or written to connection that is DISCONNECTED. The socket
6803 get's freed when the reference counter hits zero.
6805 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Changed the client operation API: channel_message operation's
6808 `sender' is now the client entry of the sender, not the nickname
6809 and the `channel' is the channel entry, not the channel name.
6811 In the private_message operation the `sender' is now also the
6812 client entry of the sender not the nickname.
6814 Affected file is lib/silcclient/ops.h and all applications
6815 using the client operations.
6817 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Moved the calling of ops->connect() from connect_to_server_final
6820 into receive_new_id functin since that is the point when the
6821 client is actually allowed to send traffic to network. The
6822 affected file is lib/silcclient/client.c.
6824 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6827 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6828 (if needs broadcasting) instead of broadcasting the packets one
6829 by one which would make a burst in the network traffic.
6831 * Added `broadcast' argument to the functions in silcd/server.[ch]
6832 silc_server_create_new_channel[_with_id] to indicate whether
6833 to send New Channel packet to primary router.
6835 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Added new function into the silcd/server.[ch] files:
6838 silc_server_create_new_channel_with_id to create new channel with
6839 already existing Channel ID.
6841 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6842 lib/silccore/silcpacket.h. This packet is used t send list of
6843 Set Mode payloads inside one packet. Server uses this to set
6844 the modes for the channels and clients on those channels, that it
6845 announced to the router when it connected to it. The protocol
6846 specification has been updated accordingly.
6848 * The silc_server_new_channel did not handle the packet coming
6849 from normal server as it normally does not send that. However,
6850 when it announces its channels it does send it. Implemented
6851 the support for that.
6853 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6854 into the file lib/silccore/id.h.
6856 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * Fixed memory leaks in the functions silc_idlist_del_client,
6859 silc_idlist_del_channel and silc_idlist_del_server in the file
6860 silcd/idlist.c. All of those leaked like a sieve.
6862 * Fixed some small memory leaks in the client's function
6863 silc_client_notify_by_server.
6865 * Added functions into silcd/server.c: silc_server_announce_clients,
6866 silc_server_announce_channels and silc_server_announce_server.
6867 These functions are used by normal and router server to announce
6868 to its primary router about clients, channels and servers (when
6869 router) that we own. This is done after we've connected to the
6872 These functions effectively implements the following packet types:
6873 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6874 and SILC_PACKET_NEW_ID_LIST.
6876 * Added new functions into the silcd/packet_receive.[ch]:
6877 silc_server_new_id_list, silc_server_new_channel_list and
6878 silc_server_new_channel_user_list to handle the incoming
6879 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6881 * Added support of changing Channel ID in the function
6882 silc_server_replace_id. If the server that announces a channel
6883 to the router already exists in the router (with same name but
6884 with different Channel ID), router is responsible to send
6885 Replace ID packet to the server and force the server to change
6886 the Channel ID to the one router has.
6888 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6889 client that the Channel ID has been changed by the router. The
6890 normal server sends this to the client. Client must start using
6891 the new Channel ID as the channel's ID.
6893 Implemented handling of this new type into lib/silcclient/client.c
6894 into the function silc_client_notify_by_server.
6896 * Added new function silc_idlist_replace_channel_id into the files
6897 silcd/idlist.[ch] to replace the Channel ID.
6899 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Call silc_server_command_identify_check always when processing
6902 the IDENTIFY command in silcd/command.c
6904 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6907 send keepalive packets. The packet can be sent by clients,
6908 servers and routers.
6910 Added function silc_socket_set_heartbeat into the file
6911 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6912 If not set, the heartbeat is not performed. The actual
6913 heartbeat is implemented in the low level socket connection
6914 library. However, application is responsible of actually
6917 Added silc_server_send_heartbeat to send the actual heartbeat
6918 packet into silcd/packet_send.[ch]. Server now performs
6919 keepalive with all connections.
6921 * Added silc_task_get_first function into lib/silcutil/silctask.c
6922 to return the timeout task with shortest timeout. There was a bug
6923 in task unregistration that caused problems. TODO has been
6924 updated to include that task system must be rewritten.
6926 * The client library will now resolve the client information when
6927 receiving JOIN notify from server for client that we know but
6928 have incomplete information.
6930 * Rewrote parts of silc_server_remove_from_channels and
6931 silc_server_remove_from_one_channel as they did not remove the
6932 channel in some circumstances even though they should've.
6934 * Encryption problem encountered in server:
6936 The LEAVE command used to send the Channel Key packet to the
6937 router immediately after generating it. However, the code
6938 had earlier sent Remove Channel user packet but not immediately,
6939 ie. it was put to queue. The order of packets in the router
6940 was that Channel Key packet was first and Remove Channel User
6941 packet was second, even though they were encrypted in the
6942 reverse order. For this reason, MAC check failed. Now, this
6943 is fixed by not sending the Channel Key packet immediately but
6944 putting it to queue. However, this is more fundamental problem:
6945 packets that are in queue should actually not be encrypted
6946 because packets that are sent immediately gets encrypted
6947 actually with wrong IV (and thus MAC check fails). So, packets
6948 that are in queue should be encrypted when they are sent to
6949 the wire and not when they put to the queue.
6951 However, the problem is that the current system has not been
6952 designed to work that way. Instead, the packet is encrypted
6953 as soon as possible and left to the queue. The queue is then
6954 just purged into wire. There won't be any fixes for this
6955 any time soon. So, the current semantic for packet sending
6958 o If you send packet to remote host and do not force the send
6959 (the packet will be in queue) then all subsequent packets to the
6960 same remote host must also be put to the queue. Only after the
6961 queue has been purged is it safe again to force the packet
6964 o If you send all packets immediately then it safe to send
6965 any of subsequent packets through the queue, however, after
6966 the first packet is put to queue then any subsequent packets
6967 must also be put to the queue.
6969 Follow these rules and everything works fine.
6971 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * Added new function silc_server_remove_clients_by_server to
6974 remove all client entries from ID list when the server connection
6975 is lost. In this case it is also important to invalidate all
6976 client entires as they hold the invalid server entry. This
6977 fixes fatal bug when server has lost connection and will reconnect
6980 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6982 * Made some sanity checks to silc_server_daemonise like to check
6983 whether the requested user and group actually exists.
6985 * Added sanity check to SKE's silc_ske_responder_finish to check
6986 that the public and private key actually is valid.
6988 * Invalidate the client's nickname when receiving Replace ID
6989 packet and the Client ID is being replaced. This means that the
6990 server will query the nickname if someone needs it (client)
6993 * Sort the ID Cache in client library when the ID Cache data
6994 has changed (needs sorting).
6996 * Do not allow for SILC client to create several connections to
6997 several servers. The client does not support windows right now
6998 and generating multiple connections causes weird behaviour.
7000 Irssi-silc client does support windows and can handle several
7001 connections without problems, see: www.irssi.org and SILC plugin.
7003 * Fixed some places where client was added to the IDList. The
7004 rule of thumb is following (in order to get everything right):
7005 If the client is directly connected local client then the
7006 `connection' argument must be set and `router' argument must be
7007 NULL to silc_idlist_add_client function. If the client is not
7008 directly connected client then the `router' argument must
7009 bet set and the `connection' argument must be NULL to the
7010 silc_idlist_add_client function.
7012 * The funtion silc_server_packet_send_local_channel actually did
7013 not check whether the client was locally connected or not. It
7014 does that now. Fixed a bug related to LEAVE command.
7016 * Fixed Remove Channel User payload parsing bug in server's
7017 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7019 * The server's silc_server_save_channel_key now checks also the
7020 global ID list for the channel as it might not be in the local
7021 list. Fixed a bug related to LEAVE command.
7023 * Is this the end of the [<unknown>] buglet that has been lurking
7024 around for a long time? A little for loop fix in server's
7025 silc_server_command_whois_parse that is used by both IDENTIFY
7026 and WHOIS command. At least, this was a clear bug and a cause
7027 of one type of [<unknown>] buglet.
7029 * WHOIS and IDENTIFY commands call the function
7030 silc_server_command_[whois/identify]_check function even if
7031 we are not router server.
7033 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7035 * Added --with-gmp configuration option. If set the GMP
7036 is always compiled in the SILC source tree. If not set then
7037 it is checked whether the system has the GMP3 installed. If
7038 it has then the GMP won't be compiled (the system's headers
7039 and library is used), if it doesn't have it then the GMP is
7040 compiled in the SILC source tree.
7042 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Changed RSA private exponent generation to what PKCS #1
7045 suggests. We try to find the smallest possible d by doing
7046 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7047 not security fix but optimization.
7049 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Added new config entry [Identity] to fork the server and run
7052 it as specific user and group. A patch from Bostik.
7054 * Imported Dotconf configuration library into lib/dotconf.
7055 This will be used to create the SILC configuration files later.
7056 It will appear in the distsribution after this commit.
7058 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * A big code auditing weekend happening. Auditing code for
7061 obvious mistakes, bugs and errors. Also, removing any code
7064 Removed files for being obsolete:
7066 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7067 inline in the file lib/silcutil/silcbuffer.h)
7069 o lib/silcutil/silcbufutil.c (the header has inline versions)
7071 Changed code to fix possible error conditions:
7073 o The buffer formatting routines now check that the destination
7074 buffer really has enough space to add the data. This applies for
7075 both buffer formatting and unformatting
7076 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7077 unformatting was changed to accomodate following rules:
7078 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7079 sent to the function while XXX_*STRING will not allocate or copy
7080 the data into the buffer. Instead it sets the pointer from the
7081 buffer into the pointer sent as argument (XXX_*STRING used to
7082 require that the pointer must be allocated already). This change
7083 makes this whole thing a bit more consistent and more optimized
7084 (note that the data returned in the unformatting with XXX_*STRING
7085 must not be freed now). The routines return now -1 on error.
7087 o Tried to find all code that use buffer_format and buffer_unformat
7088 and added return value checking to prevent formatting and
7089 especially unformatting errors and possible subsequent fatal
7092 o Changed ske->x and ske->KEY to mallocated pointers in
7093 lib/silcske/silcske.h. Fixed possible data and memory leak.
7095 o Added return value checking to all *_parse* functions. Fixed
7096 many memory leaks as well.
7098 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7099 so that buffer overflows would not happen. All code now also
7100 checks the return value as it can fail.
7102 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Added reconnection support to server if the normal server looses
7105 its connection to the router (for example if router is rebooted).
7106 The server performs normal reconnection strategy implemented
7107 to the server. Affected file silcd/server.c.
7109 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Added new packet type SILC_PACKET_SET_MODE that is used to
7112 distribute the information about changed modes (for clients,
7113 channels and clients channel modes) to all routers in the
7114 network. Updated the protocol specification accordingly.
7116 Added functions into silcd/packet_send.c and
7117 silcd/packet_receive.c: silc_server_send_set_mode,
7118 silc_server_set_mode.
7120 Added new files silcmode.[ch] into lib/silccore that implements
7121 the encoding and decoding of Set Mode Payload. Added new type
7122 SilcSetModePayload. Moved the definitions of different modes
7123 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7125 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Oops, a little mistake in server's connection authentication
7128 protocol. The protocol is not ended with FAILURE but with
7129 SUCCESS if the authentication is Ok. :) Affected file is
7132 * Implemented NICK_CHANGE notify handling in server in the file
7133 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7134 the local clients on the channel. After the changing nickname
7135 in router environment snhould work and the [<unknown>] nickname
7136 should appear no more.
7138 The silc_server_replace_id function that receives the Replace ID
7139 payload now sends the NICK_CHANGE notify type also in the file
7140 silcd/packet_receive.c
7142 * Changed WHOIS and IDENTIFY command to support the maximum amount
7143 of arguments defined in protocol specs (3328 arguments). This
7144 fixed a bug that caused problems when there were more than three
7147 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Added extra parameter, command identifier, to the
7150 silc_client_send_command so that explicit command identifier
7153 Changed that ID list routines uses specific command identifier
7154 when sending WHOIS/IDENTIFY requests to the server so that they
7155 can be identified when the reply comes back.
7157 Affected files lib/silcclient/command.[ch],
7158 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7160 * Added `sender' argument to silc_server_packet_send_to_channel
7161 to indicaet the sender who originally sent the packet to us
7162 that we are now re-sending. Ignored if NULL. Affected file
7163 silcd/packet_send.[ch].
7165 * Added some server statistics support in silcd/server_internal.h
7166 SilcServerStatistics structure and around the server code. Also
7167 send some nice statistics information when client is connecting
7170 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Fixed channel ID decoding in server's JOIN command reply in
7173 silcd/command_reply.c
7175 * Fixed braodcasting of replace ID payload to not to send it if
7176 we are standalone server in silcd/packet_receive.c.
7178 * Fixed all channel message sending routines to not to send
7179 packets to clients that has router set, since they are routed
7180 separately in the same function earlier. Affects file
7181 silcd/packet_send.c and all channel packet sending functions.
7183 * In USERS reply, res_argv[i] are not allocated, the table
7184 is allocated. Thus changed that free the table, not its
7187 * In server's whois_check and identify_check if the client is
7188 locally connected do not send any WHOIS commands - they are not
7191 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7193 * Fixed some minor bugs in client when sending WHOIS command. The
7194 arguments was in wrong order.
7196 * Removed statis function add_to_channel from server in
7197 silcd/command.c that was previously used with the joining but
7200 * Tested USERS command in router environment successfully with two
7201 routers, two servers and two clients.
7203 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Reorganized the USERS command and command reply in client library
7206 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7207 When the command is given by user we register a pending command
7208 callback that will reprocess the command after the reply has been
7209 received from the server. When reprocessing the packet we then
7210 display the information. Thus, the USERS information is displayed
7211 now in the command callback instead of in the command reply
7212 callback. The processing of the command is same as previously
7213 when server has sent the command reply in the JOINing process.
7215 * Added to USERS command in silcd/command_reply.c to join the client,
7216 we didn't use to know about, to the channel after we've created
7217 a client entry for it. Also, for clienet we did know already still
7218 check whether it is on the channel or not and add it if not.
7220 * Removed silc_server_command_join_notify as the function and its
7223 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Changed the client's pending command handling to the same as the
7226 server's pending command handling. It is also now possible to
7227 execute command reply functions from other command reply
7228 function as the function callbacks for commands and command
7229 replies are one and same. The pending commands are not static
7230 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7231 in client connection context. Thus, pending commands are server
7232 connection specific as it is convenient.
7234 Changed the function silc_client_command_pending and
7235 silc_client_command_pending_del and added new function
7236 silc_client_command_pending_check. Removed the
7237 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7240 * Added cmd_ident, current command identifier, to the client
7241 connection context in lib/silcclient/client.h to keep track on
7242 command identifiers used in command sending. Client's command reply
7243 function handling now supports the mandatory command identifiers.
7245 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7246 funtions in client to fully support pending command callbacks.
7248 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7249 as one of the arguments to the application in the command reply
7252 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7253 before first releasing SILC but came back. Now it is removed again
7254 and should come back nomore. The FORWARDED flag was used only
7255 by the JOINing procedure by forwarding the command packet to router.
7256 Now, the JOINing procedure has been changed to more generic (due
7257 to various router environment issues) and FORWARDED is not needed
7258 anymore for anything. The protocol specification is yet to be
7261 Now, removed silc_server_packet_forward from server and the flag
7262 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7264 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Renamed NAMES command to USERS command. The NAMES was named that
7267 due to historical reasons. Now it is renamed. Also, rewrote
7268 parts of the USERS command. The nickname list is not sent anymore
7269 by the server. Only Client ID and mode lists are sent in the USERS
7270 command. Changed this also to the protocol specification.
7272 The client now resolves the names and stuff after it receives
7273 the USERS list from the server when joining to the channel.
7275 * WHOIS and IDENTIFY commands has been changed to support multiple
7276 Client ID's per command. One can now search for multiple users
7277 in the network by sending only one WHOIS or IDENTIFY command.
7278 Changed the code and the protocol specifications.
7280 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7281 uses silc_server_command_whois_parse to parse the request. */
7283 * If normal server, do not parse the WHOIS and IDENTIFY requests
7284 before sending it to the router. Saves some time.
7286 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7288 * Fixed JOIN command on client library. Wrong number of arguments
7289 used to crash the client.
7291 * Added silc_server_channel_has_global function to check whether
7292 channel has global users or not.
7294 * Added silc_server_channel_has_local function to check whether channel
7295 has locally connected clients on the channel.
7297 * The silc_server_remove_from_one_channel now checks whether the
7298 channel has global users or not after given client was removed from
7299 the channel. It also checks whether the channel has local clients
7300 on the channel anymore. If it does not have then the channel entry
7301 is removed as it is not needed anymore.
7303 * The silc_server_notify now checks on JOIN notify whether the joining
7304 client is one of locally connected or global. If it is global then
7305 the channel has now global users on the channel and that is marked
7306 to the channel entry. Also, it now saves the global client to
7307 global list who is joining and JOINs it to the channel. This is
7308 for normal server, that is.
7310 Changed silc_server_send_notify_on_channel,
7311 silc_server_packet_relay_to_channel and
7312 silc_server_packet_send_to_channel check if we are normal server
7313 and client has router set (ie. global client) do not send the
7314 message to that client, as it is already routed to our router.
7316 * Implemented LEAVE notify type handling in silc_server_notify
7319 * Tested LEAVE command in router environment successfully. Tested
7320 with two routers, two servers and two clients.
7324 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7326 * Implemented SIGNOFF notify type handling in silc_server_notify
7329 * silc_server_remove_id now removes the client entry from all channels
7330 it has joined and thusly sends SIGNOFF notify type.
7332 * Rewrote the NAMES list generation in server by removing two excess
7333 loops. The lists are created now inside one loop.
7335 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7337 * silc_server_remove_channel_user checks now also global list
7338 for channel and client.
7340 * silc_server_new_channel_user checks now both local and global
7341 list for channel and client. Fixed a bug in client id decoding.
7342 Used to decode wrong buffer.
7344 * silc_server_channel_message checks now both local and global
7345 list for channel entry.
7347 * Tested channel joining (hence JOIN) in router environment
7348 successfully. Tested with two routers, two servers and two
7351 * Tested channel message sending in router environment successfully.
7353 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7355 * Added silc_server_save_channel_key into server.[ch] to save the
7356 received channel key in Channel Key payload processing. It is
7357 also used in JOIN command reply handling.
7359 Equivalent function silc_client_save_channel_key added into
7360 client.[ch] into client library.
7362 * Changed JOIN command reply to send information whether the channel
7363 was created or not (is existing already) and the channel key
7364 payload. Changed protocol specs accordingly.
7366 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7367 the request was sent by ID and not by nickname. Crashed on
7370 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7373 now correctly save the received data.
7375 * silc_server_free_sock_user_data now notifies routers in the
7376 network about entities leaving the network.
7378 At the same time implemented functions silc_server_remove_id
7379 and silc_server_send_remove_id to receive and send REMOVE_ID
7380 packets. The packet is used to notify routers in the network
7381 about leaving entities. The ID removed will become invalid in
7384 * Added function silc_idlist_del_server into server. Removes and
7385 free's server entry from ID list.
7387 * silc_server_private_message function now checks, if we are router,
7388 that the destination ID really is valid ID, naturally.
7390 * In router when NEW_ID packet is received (for new client) the
7391 hash of the Client ID is saved in the ID Cache but the
7392 client->nickname is set to NULL, instead of putting the hash
7395 IDENTIFY command now also checks that client->nickname must be
7396 valid. If it is not if will request the data from the server who
7397 owns the client. Added new function
7398 silc_server_command_identify_check.
7400 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7401 to set the command to already allocated Command Payload.
7403 * Tested private message sending in router environment with two
7404 routers, two servers and two clients. Fixed minor bugs and now
7407 * Fixed segfault from client's NAMES command. Used to crash if
7410 * Forwarded packets must not be routed even if it is not destined
7411 to the receiver. Changed server code comply with this.
7413 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7415 * Added `require_reverse_mapping' boolean value to ServerParams
7416 structure. If TRUE (not default) the server will require that
7417 the connecting host has fully qualified domain name.
7419 If the reverse mapping is not required and hostname could not be
7420 found the IP address is used as hostname.
7422 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7424 * Implemented version string checking to both client and server.
7425 The check is incomplete currently due to the abnormal version
7426 strings used in development version of SILC.
7428 * Changed all command functions in server to use the new
7431 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Changed char *data to unsigned char *data in ID Cache system to
7434 support binary data as ID Cache data. Changed code to support
7435 binary data in lib/silccore/idcache.c.
7437 * Renamed silc_server_packet_relay_command_reply to
7438 silc_server_command_reply as it is normal packet receiving
7439 function. Rewrote the function to accept command replys for
7440 servers and not only for clients.
7442 * Mark remote router always as registered server if we are connecting
7443 to it. Otherwise, commands sent by the router to us are ignored.
7445 * All ID List find routines now returns the ID Cache Entry pointer
7446 as well if requested.
7448 * WHOIS command works now in router environment, tested with two
7449 routers, two servers and two clients.
7451 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7452 in router environment (as it is almost equivalent to WHOIS) but
7453 hasn't been tested thoroughly. Added new functions:
7455 silc_server_command_identify_parse
7456 silc_server_command_identify_send_reply
7457 silc_server_command_identify_from_client
7458 silc_server_command_identify_from_server
7460 * Disabled route cache adding because adding two different ID's with
7461 same IP replaces the old cache entry thus giving wrong route.
7462 The entry->router->connection is always the fastest route anyway
7463 so route cache may not be needed. Of course, new routes maybe
7464 established after receiving the ID when the entry->router->connection
7465 might not be anymore the most optimal.
7467 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7469 * Add route cache for received ID for fast routing.
7471 * Added silc_server_packet_route to route received packet on router
7472 that is not destined to us.
7474 * Renamed silc_server_get_route to silc_server_route_get.
7476 * Added id_string and id_string_len fields into SilcServer to
7477 include encoded ServerID for fast comparing without excess
7478 encoding of the ID's.
7480 * Cleaned up WHOIS command on server side. Added following static
7483 silc_server_command_whois_parse
7484 silc_server_command_whois_check
7485 silc_server_command_whois_send_reply
7486 silc_server_command_whois_from_client
7487 silc_server_command_whois_from_server
7489 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7490 arguments in command replies. All command functions should be
7491 updated to use this macro.
7493 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Minor typo fixes on command reply handling on server.
7497 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added silc_server_command_add_to_channel internal routine to add
7500 the client to the channel after router has created the channel and
7501 sent command reply to the server.
7503 * Added generic silc_server_send_command to send any command from
7506 * Use static buffer with ID rendering instead of duplicating data.
7508 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Fixed a channel user mode bug when joining to a channel server gave
7511 everybody channel founder rights, oops.
7513 * We mark ourselves as the router of the incoming server connection
7514 if we are router ourselves. This way we can check in some packet
7515 sending functions whether it is locally connected server. For
7516 incoming router connections we put NULL.
7518 * For router sending packets locally means now always sending the
7519 packet cell wide; to local clients and local servers. For normal
7520 server sending packet locally means sending it to only local
7523 * Fixed the JOIN command to really work in router environment. If the
7524 channel is created it is always created by the router. Router is
7525 also responsible of making the initial joining to the channel,
7526 sending JOIN notify to the sending server and distributing
7527 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7528 does not exist server doesn't do anything else but forward the
7529 command to the router which performs everything.
7531 * Added silc_server_send_channel_key function to send the Channel Key
7534 * Added silc_server_create_channel_key to create new channel key. The
7535 channel key is now re-generated everytime someone joins or leaves
7536 a channel, as protocol dictates. Note: channel->key_len is the
7539 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7542 packet_receive.[ch] to separate packet sending and receiving
7543 routines. The server.[ch] now includes everything else including
7544 actual packet processing (writing and reading data) and other
7547 Renamed silc_server_private_message_send_internal to
7548 silc_server_send_private_message. The routine is still though
7549 used only to relay private messages as server does not send
7550 private messages itself.
7552 Renamed silc_server_new_channel to silc_server_create_new_channel
7553 and added new function sicl_server_new_channel that handles the
7554 incoming New Channel packet. Added also new sending function
7555 silc_server_send_new_channel to send New Channel Payload.
7557 * Added new function silc_server_notify to process incoming notify
7558 packet to the server/router. Server may then relay the notify
7559 to clients if needed.
7561 * Added new function silc_server_new_channel_user to process incoming
7562 New Channel User packet. Router will redistribute the packet and
7563 send JOIN notify to its local clients and locally connected servers
7564 if needed. Normal server will send JOIN notify to its local client
7565 on same channel when received this packet. Added also corresponding
7566 sending function silc_server_send_new_channel_user to sent the
7569 * Added boolean route argument to send_notif_to_channel and
7570 packet_send_to_channel functions to attempt to route the packet
7571 if it is TRUE and send only locally if it is FALSE.
7573 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * silc_server_replace_id now broadcasts the received replace ID
7576 packet if it is not broadcast packet already. The router must
7577 broadcast to inform other routers about changed ID.
7579 * Added backpointer to server's router into SilcServer context in
7580 silcd/server_internal.h.
7582 * Fixed silc_server_packet_broadcast to send correct broadcast
7585 * The channel key is now distributed to the local client as soon
7586 as it is received from the router (in router environment) so that
7587 no other packet may be sent for the channel until client has
7590 * silc_server_remove_channel_user now broadcasts the received
7591 Remove Channel User packet if it is not broadcast packet already.
7592 The router must broadcast to inform other routers about removed
7595 * Added users field into SilcPacketContext that is a reference count
7596 of the context. One can increase the reference count by calling
7597 silc_packet_context_dup which is now changed to just increase the
7598 reference count instead of duplicating the data. The reference
7599 count is decresed by calling silc_packet_context_free that will
7600 free the data after the reference count hits zero.
7602 For now on the packet context and everything allocated into it
7603 (including the raw packet from network) must be freed by calling
7604 the new silc_packet_context_free function. Added also new function
7605 silc_packet_context_alloc that must be used now to allocate the
7606 context. This also means that if a routine is asynchronous from
7607 silc_[client/server]_packet_parse_type the packet context must
7608 be duplicated by calling silc_packet_context_dup. Otherwise it
7609 gets free'd after silc_[client/server]_packet_parse_type returns.
7610 Also, one must remember that if packet is duplicated then its
7611 reference count must be decresed by calling the free function as
7612 many times as it was duplicated.
7614 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7615 from both client and server.
7617 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * Made joining to a channel working in router environment.
7621 * Cleaned up JOIN command on server side and create function
7622 silc_server_command_join_channel internal routine to make the
7625 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7627 * Changed silc_command_pending list to SilcDList. Also, added
7628 `ident' field to SilcServerCommandPending structure to identify
7629 the reply and to call correct callback.
7631 Added silc_server_command_pending_check function to replace the
7632 corresnponding macro. The silc_command_pending list is not
7635 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7636 to set identifier to previously allocated Command Payload. It
7637 is used to set identifier for command when resending Command
7640 * Added silc_command_payload_encode_payload to encode Command
7641 Payload buffer from SilcCommandPayload structure.
7643 * Added silc_argument_payload_encode_payload to encode Argument
7644 payload buffer from SilcArgumentPayload structure.
7646 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7648 * Changed WHOIS command to support router connection on server side.
7649 The whois request is always sent to router unless the server is
7650 standalone server. After server has received the reply from the
7651 router will it send the reply to the client.
7653 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7654 broadcast received broadcast packet. The function is used only
7655 by router. The broadcast packet is always sent to the router's
7658 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7659 render given ID to printable string, for log files for example.
7661 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7663 * Made basic router to router connections working. At least they
7664 can now connect to each other but nothing really works the way
7665 they are supposed - yet.
7667 * Added new initiator token to RouterConnection configuration
7668 file in silcd/serverconfig.[ch]. It is used to tell whether we
7669 are the initiator to the remote router or whether we'll expect
7670 the other end to connect.
7672 * Moved registering of listener task to silc_server_init, hence
7673 the server starts listenning as soon as it is run, even if it
7674 does not have connections to other routers. Let's see how well
7677 * Changed default connection retry timeouts for more suitable in
7680 * Removed cipher and such arguments from silc_idlist_add_client
7681 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7682 Added new function silc_idlist_add_data to add the keys and stuff
7685 * Added SilcIDListData structure and added it to SilcClientEntry
7686 and SilcServerEntry as their first field in the structure. This
7687 way we can explicitly cast the ID entries to the SilcIDListData
7688 structure and get common data for the entries. In past, we had
7689 to first check what type of connection it is and then cast it to
7690 correct ID entry type. Now, we can directly cast the opaque
7691 pointer to the SilcIDListData (no matter what ID entry it actually
7692 is) and get the data needed.
7694 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7697 in some circumstances even if threre were timeout tasks, though not
7698 IO tasks, but tasks anyway. Now fixed.
7700 * Defined SilcServerConnection structure to hold connection specific
7701 stuff about directly connected servers and routers. The definition
7702 is currently in silcd/server_internal.h. I thought about having
7703 a bit more important role fro this struct but for now it is used
7704 only when connecting to other server (or router actually).
7706 * Added connecting retry support in server when connecting to
7707 router(s). The retry feature implement exponential backoff
7708 algorithm. Also, added SilcServerParams structure to hold default
7709 parameters for server. For now, it include these retry settings
7710 and are hard coded. After server is moded to be as Silc Server
7711 Library this structure will be more important.
7713 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7715 * Changed client librarys channel->clients table to SilcList and
7716 changed code accordingly.
7718 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Changed client's channel table to SilcList and changed code
7721 accordingly. Also changed SilcChannelClientEntry to include back-
7722 pointer to the channel so that client entry can use that structure
7723 as list as well and we have fast cross-reference to the channel.
7724 This change dramatically decreased the complexity of channel
7725 handling with client entry and vice versa (removed one extra
7726 loop when searching for channel entry from many functions).
7728 * Changed server->sim from table to SilcDList and changed code
7731 * NAMES command can now be used from user interface. It will show
7732 the user list on the channel, neatly.
7734 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7735 Code now saves realname of the user if it becomes available.
7737 * Renamed configure.in to configure.in.pre and made ./prepare
7738 script to automatically add correct version string to
7739 configure.in which it creates from configure.in.pre.
7741 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7743 * NAMES command reply now shows users mode with the nickname when
7746 * Moved silc_client_ch[u]mode[_char] functions from
7747 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7748 place sucks, they are utility functions and should be in some
7751 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7753 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7756 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Added TRQ (efficient deque and list library) into lib/trq. This is
7761 a very good list library that is currently used in the SILC. Defined
7762 SilcList API over the library because I didn't like the API very
7763 much. See lib/trq/silclist.h for the API and examples of how to
7764 use the API. Fixed various places in the code to use the new
7765 SilcList API. The SilcList is meant for lists that has a structure
7766 already defined as a list. It is not suitable to add just some
7767 context to the list (in TRQ, the context is the list actually).
7769 So, I defined SilcDList that can be used for the purpose where
7770 predefined list structure does not exit. This can be used as
7771 such list. Now some context just can be added to the SilcDList.
7772 Currently this list is not used in the SILC just yet, though there
7773 are a lot places where this can replace dynamically allocated
7774 tables and I will fix these places, later, to use SilcDList.
7775 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7776 and use TRQ internally).
7778 Also fixed some annoying warning messages that the original TRQ
7779 code generated. Also minor changes to TRQ's Makefile.in.
7781 * Added support for querying by Client ID to both WHOIS and
7782 IDENTIFY commands into server, as required by the protocol.
7784 * Removed method function pointers from SilcBuffer structure. They
7785 weren't used to anything and just increased the context size for
7786 no good reason. This change also made silc_buffer_alloc and
7787 silc_buffer_free functions inline functions.
7789 * Disabled command flooding detection support until it's fixed so
7790 that it accepts commands in but does not execute them more than once
7793 * Added silc_net_localhost(), to return local hostname, into
7794 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7795 that must be initialized before calling silc_client_init.
7797 * Added new function: silc_server_send_notify_on_channels to send
7798 notify messages to all channels client has joined. It is assured
7799 that the message is sent only once per client.
7801 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7802 lib/silcutil/silcutil.[ch] as silc_format function. The new
7803 function is generic and is used by server as well, not only by
7804 the logging routines.
7806 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7807 the provided version string was not acceptable. Added new function:
7808 silc_ske_check_version into lib/silcske/silcske.h. The function
7809 must be implemented by the application (client or server) and it
7810 does not reside in the SKE library. The function checks the version
7811 string remote end sent.
7813 * Added back pointers (to opaque context and to SilcSocketConnection)
7814 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7816 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7817 duplicate packet context structure.
7819 * Changed `notify' client operation to send same arguments as client
7820 receives from server except for ID's. ID's are mapped to correct
7821 ID entry and that is returned. Also, if channel entry is not sent
7822 by server but the notify is for channel the channel entry is sent
7823 to application (otherwise application doesn't know that it is for
7824 channel (library gets it from packet's Destination ID)).
7826 * Added silc_client_remove_from_channels into client library to
7827 remove a client from all channels it has joined to. Used when
7828 received SIGNOFF notify from server. Added also new function
7829 silc_client_replace_from_channels to replace old ID entry with
7830 new ID entry on all channels. Used when received NICK_CHANGE
7833 * Fixed ID Cache list handling in silc_idlist_get_client in
7834 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7835 to get (or query) client by ID.
7837 * Updated TODO list.
7839 * Added connection authentication status message defined by the
7840 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7841 support for these into the code in client and server side.
7843 * Added generic function silc_client_send_command to send any command
7844 with variable argument list. Application should use this function
7845 to send commands if the command functions provided by the library
7846 does not suite for the application's user interface needs.
7848 * Added new `failure' client operation. Application is notified about
7849 received failure packet if client is executing a protocol. In this
7850 case the protocol's execution has failed.
7852 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7853 is required by the protocol.
7855 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7856 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7859 * Added status flag to SilcSKE object to indicate realtime status
7860 of the SKE protocol.
7862 * Application receives now exactly same command reply arguments as
7863 the library receives from server. However, if ID is received the
7864 corresponding ID entry is returned to the application (eg. Client
7865 ID is mapped to correct SilcClientEntry entry and that is returned).
7866 Changed command_reply client operation due to this change.
7868 * Changed all ID's in commands and in command replys as ID Payloads.
7869 Change affected both client and server side codes.
7871 All ID's sent in SILC network (with execption of ID's in SILC
7872 Packet header) are sent in ID Payload to support variable length
7875 * Server now notifies nick changes and notifies all clients on
7876 the channels about the new nickname (about the new Client ID,
7879 * Implemented CMODE command to change channel modes. Supports all
7880 channel modes defined by the protocol specs except ban and invite
7881 lists. (Also, private channel key mode is supported but support for
7882 setting private channel key in client is missing, thus, this mode
7883 has no effect on client side (except that server requires that the
7884 client uses private channel key and normal channel traffic does not
7887 Also, invite mode works per se, but INVITE command does not work
7888 yet correctly, so you can set channel as invite only channel but
7889 inviting clients to the channel does not work (it is yet to be
7890 thought what's the best way to do it).
7892 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7893 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7894 Implemented CUMODE command to change user's mode on the channel.
7895 Supports all modes defined by the protocol specs.
7897 * Added NAMES command reply to return users modes on the channel.
7899 * Removed unnecessary and slow ciphers from lib/silccrypt.
7901 * Set SO_KEEPALIVE option to connection sockets by default.
7903 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7905 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7906 redefined the Notify Payload into protocol specs.
7908 * Added silc_id_payload_parse_id to get ID directly from raw
7911 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7913 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7914 accept searching by Client ID as well.
7916 * Added support for LEAVE and SIGNOFF notify types in client library.
7918 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7919 to parse ID Payload from raw data.
7921 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7923 * Added flags parameter into silc_ske_assemble_security_properties
7924 function in lib/silcske/silcske.[ch].
7926 * Changed notify client operation to fit better for notify messages
7927 sent by server. The notify payload received from server is now
7928 passed to the application (after parsing it to SilcNotifyPayload).
7929 It is application's responsibility to retrieve the arguments
7930 from the payload and show the message the way it wants. The message
7931 sent by server is implementation specific.
7933 * Changed public keys to comply with the protocol specification.
7934 Old public keys are not supported anymore and are not compatible.
7936 * Removed nickname from Channel Payload as the latest draft removed
7937 it. The client must resolve the nickname from the NAMES command
7938 reply received when it joined the channel.
7940 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7942 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Fixed some errors in protocol specification drafts.
7946 * Created lib/silccore/silcnotify.c to implement Notify Payload
7947 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7948 generic payloads described by protocol specifications. The file
7949 includes implementations for ID Payload and Argument Payload.
7951 * Changed Command Payload implementation to use the new Argument
7952 Payload. Changed command_xxxx_payload to command_payload_xxxx
7953 to comply with SILC coding conventions.
7955 * Added suppport for Argument Payload handling in Notify Payload
7956 implementation as protocol requires it. Added the new support
7957 into server and client lib as well.
7959 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7961 * Added support for multiple nicknames on same channel. [n] is
7962 added locally to the nickname if there are more than one same
7963 nicknames on the channel.
7965 * Server now sends all nicknames that matched WHOIS request.
7966 Client also shows the list received from server.
7968 * Added TOPIC command to client side. User can now set and show
7969 current topic on channel.
7971 * Added MOTD command to client and server. Also, server sends the
7972 motd when client connects to the server.
7974 * Changed version strings to comply ISO 8601.
7976 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Fixed protocol error handling in client library. It should now
7979 cope even if the SKE fails for some reason.
7981 * Made new protocol specification drafts for submitting to IETF.
7983 * Implemented TOPIC command to server in silcd/command.c.
7985 * Added two new notify types into lib/silccore/silcnotify.h:
7986 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7987 notify nickname change and topic setting/change on a channel.
7989 * API change of command_reply operation in client library. The
7990 application gets now the status type received from server as well.
7992 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7994 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7996 * Cras fixed and optimized the packet handling even further and
7997 it should work now. Minor change to the prototype of function
7998 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8000 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8002 * Added new function into lib/silcutil/silcschedule.[ch]:
8003 silc_schedule_with_fd to select() a specified fd. The function
8004 returns after timeout expires or data arrives or goes. The
8005 function is used by packet routines to wait that all data is
8006 received from network.
8008 * Fixed data reading from network in lib/silccore/silcpacket.c.
8009 The code now assures that all data is read from the fd and then
8010 continues packet processing. This was a bug fix since the code
8011 used to drop some data in some circumstances.
8013 * Added new function into lib/silcclient/client.[ch]:
8014 silc_client_start_key_exchange to start key exchange after
8015 connection has been established to server. The code internally
8016 now uses this funtion but its main purpose was to provide it
8017 for applications that perform their own connecting. After
8018 application has created a connection it merely calls this
8019 function to start the key exchange between client and server.
8020 The library takes care of everything else after that.
8022 Updated also lib/silcclient/README to explain the usage of
8025 * Do not send to application information that connection has
8026 been established. Application gets notified it by connect
8029 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Applied cras's patch to add silc_schedule_one function. The
8032 function runs scheduler once and returns.
8034 * Fixed the scheduler after cras messed it up. The timeout
8035 handling works now as it's supposed to work.
8037 * Added into lib/silccore/ silcnotify.h to include notify
8038 message types support. Changed silc_server_send_notify*
8039 functions, in server.[ch], to support those new notify types.
8040 Added the support for the notify types into client library,
8041 as well. Added new notify client operation into ops.h in
8044 * Changed silc_server_packet_send_to_channel to send normal
8045 packets instead of just channel message packets. The function
8046 is now used to send the notify packets to channels. It is not
8047 used to send channel message packets anymore, as server never
8050 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8051 va_arg()s as it seems to require it nowadays. I guess, if SILC
8052 is compiled with older va_arg() the new code should work anyway.
8054 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8056 * Splitted core library. Core library (lib/silccore) includes
8057 now only SILC protocol specific core (and common) components.
8058 Created new utility library (lib/silcutil) that includes more
8059 generic purpose stuff. The stuff for util library was taken
8060 from the old core library. This was minor and easy split.
8062 * Created SILC Client Library (lib/silcclient) that includes
8063 implementation of the SILC client without user interface. This
8064 was major move from silc/ directory. The code has been changed
8065 so that it is transparent towards the user interface. The
8066 silc/ directory includes now the same user interface as before
8067 and it uses the new client library. Read lib/silcclient/README.
8068 Basicly, the client library performs everything else related
8069 to SILC except user interface handling. Also, configuration
8070 files are considered to be part of user interface and library
8071 does not handle them.
8073 This change also changed a lot of structures, function naming etc.
8074 Most important change was that SilcClientWindow object was
8075 renamed to SilcClientConnection in the client library. Created
8076 also new file lib/silcclient/ops.h. Also added new files
8077 silc/local_command.[ch] and silc/client_ops.[ch].
8079 All these changes were made to make it easier for user interface
8080 designers to create what ever user interface for the SILC client
8083 It is also expected that the server will be moved to lib
8084 directory as well and SILC Server Library will be created;
8085 sometimes in the future.
8087 * Removed Local commands from lib/silccore/silccommand.h as
8088 they are application specific and new client library does not
8089 handle any of those anymore.
8091 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8092 old client implementation in silc/.
8094 * Added support for callback functions in SILC_LOG_* macros.
8095 Application can now set its own callbacks that will be called
8096 instead of using the default functions that will always print
8097 the debug messages to stderr (or stdout). Also, debugging can
8098 now be disabled by setting silc_debug to FALSE and re-enabled by
8099 setting it to TRUE. Note, that logging will still work even
8100 if debugging is disabled.
8102 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8103 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8104 silc_log_reset_debug_callbacks.
8106 * To enable debugging in silc client one must give now -d
8107 option on command line.
8109 * Changed silc_schedule_init to automatically allocate task queues
8110 if they are not allocated before calling it.
8112 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8114 * Added GMP 3.1 into math library.
8116 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8118 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8119 a channel in SILC network. The packet is used by servers and
8120 routers to notify other routers that user has left a channel.
8121 This little feature was missing until now. Added the feature
8122 to protocol specification as well.
8124 Added functions: silc_server_send_remove_channel_user and
8125 silc_server_remove_channel_user into server.[ch].
8127 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8128 lib/silccore/silcpacket.h. However, they are not implemented
8131 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Fixed joining to a channel and sending channel messages
8134 between server and router. The channel message sending should
8135 now work inside a cell.
8137 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8139 * Fixed the private message sending between server and router.
8140 The private message sending should now work inside a cell.
8142 * Added silc_server_replace_id into server.[ch] to replace
8143 existing ID in the SILC network.
8145 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8146 and silc_idlist_replace_server_id into idlist.[ch] in server.
8148 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8150 * Fixed the server to server connections. Server can again now
8151 connect to router. Router to router connections probably does
8154 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Added dynamic protocol registering support. Now protocols can
8157 registered and unregistered on the fly. Patch by cras.
8159 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8161 * Added lib/contrib directory to hold routines that some platforms
8162 don't have but are needed by SILC.
8164 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8165 into lin/contrib to provide getopt() and getopt_long() for
8166 those who don't have it.
8168 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8170 * Added AWAY command to client. When away message is set and
8171 client receives a private message packet the client automatically
8172 replies to the sender with the away message.
8174 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8175 bug seemed to be the cause of recent problems when compiling
8178 * Added version detection support to SKE protocol specification
8179 and added the new changes to the SKE implementation as well.
8180 There were other minor changes in the SKE protocol as well.
8182 Many changes in lib/silcske/silcske.[ch] and in
8183 lib/silcske/payload.[ch].
8185 * Added ^U functionality, clear input line. Patch from cras.
8187 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8189 * Mainly small bugfixes on core library. Fixed some debugging
8190 logging and buffer overflow in silclog.c.
8192 * Updated config.sub and config.guess on the distribution tree.
8194 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Added command lagging support in server. Client may execute
8197 commands now only once in two seconds.
8199 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8201 * Optimized packet reception. MAC computation and checking is now
8202 also more optimized. A lot previously duplicated code is now
8203 used as generic by both client and server.
8205 * Fixed key pair generation in clientutil.c
8207 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8209 * Added into lib/silccore/silcbufutil.[ch] new function;
8210 silc_buffer_realloc.
8212 * Moved generic packet sending/encryption functions to
8213 lib/silccore/silcpacket.[ch] from client and server. Some
8214 rewriting of the functions.
8216 * Moved all generic packet reception/decryption functions to
8217 lib/silccore/silcpacket.[ch] from client and server. The
8218 packet processing is now much cleaner in both client and server.
8219 These were major changes in both client and server.
8221 * Created many common functions in server to do packet sending.
8222 Previously code were duplicated a lot, this has been removed
8225 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8227 * Rewrote major parts of the ID cache system. Don't know
8228 whether it is better now or not but at least the API is more
8231 * Major rewrite on ID cache stuff on client because of the ID
8232 cache API changes. Added idlist.c to client.
8234 * Also major rewrite on ID cache stuff on server as well.
8235 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8236 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8237 in hand, instead they are all put into the ID cache system now.
8238 All server_idlist_* routines uses ID cache now instead of
8239 traversing its own lists (those lists does not exist anymore).
8240 SilcIDList though still exists. Also, SilcXXXEntry's are
8243 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * Finally made the SKE implementation compliant to the protocol
8246 specification. All mp integers are now binary encoded as
8247 opposed being HEX encoded.
8249 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8252 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8253 functions: silc_[encode/decode]_pem. Also added function
8254 silc_encode_pem_file to PEM encode with newlines ('\n') for
8257 * SILC public keys are now encoded either PEM or binary. Same
8258 option is for private keys as well. By default private keys
8259 are binary encoded and public keys PEM encoded. Silly HEX
8260 encoding were removed.
8262 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8263 function to create fingerprints.
8265 * Fixed a bug in SHA1; does not change the original data anymore.
8267 * Partly implemented INFO command on client and server side.
8268 Fixed CLEAR command. Changes to SERVER command; show current
8269 server(s) when giving command without arguments. Added
8270 VERSION command to client.
8272 * Added check to server that unregistered connections cannot
8273 execute commands (unless it is specificly allowed).
8275 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Fixed screen refresh.
8279 * Fixed channel joining bug from client. On some circumstances
8280 client tried to join to a channel it had already joined.
8282 * Added public key verification process into client's protocol.c.
8283 The client now verifies the public key from user and saves
8284 it into ~./silc/serverkeys/ directory.
8286 Added into: clientutil.[ch]: silc_client_verify_server_key.
8288 * Changed SKE protocol's silc_ske_initiator_finish function
8289 to accept callback function that verifies the received public
8290 key. Removed old silc_ske_verify_public_key function.
8292 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8294 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8295 silc_pkcs_private_key[_data]_set.
8297 * Made the password and public authentication more cleaner in
8298 server's protocol.c.
8300 * Removed historic and obsolete protocol `channel_auth' from
8301 both client and server.
8303 * Removed wrong way of sending command status messages from
8304 server to client in server's command.c. The old way violated
8305 protocol specification.
8307 Changes to silccore/silccommand.[ch]: removed
8308 silc_command_encode_status_payload -> not needed anymore,
8309 changed silc_command_encode_payload_va to accept extra
8310 argument on variable argument list. The argument type must
8311 now be provided to the function. Also, added new function:
8312 silc_command_encode_reply_payload_va which is same as
8313 normal command_encode_payload_va except command status type
8314 is provided as extra argument.
8316 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8318 * Added ~./silc directory handling. The directory includes the
8319 public and private keys for the client.
8321 Added silc_client_check_silc_dir, silc_client_create_identifier
8322 and silc_client_load_keys.
8324 * Implemented SILC protocol compliant public key. Added public
8325 and private key saving to and loading from files.
8327 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8328 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8329 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8330 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8331 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8333 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8334 silc_pkcs_load_[public/private]_key.
8336 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8338 * Added silc_server_get_route (route.[ch]) to get connection
8339 data for the fastest route for given ID.
8341 * Implemented INVITE command on client and server. The command
8342 were re-defined in the SILC Protocol Specification and the
8343 implementation now complies with the specification.
8345 * Implemented PING command on client and server.
8347 * Implemented NAMES command on client and server. The server side
8348 supports currently only normal server not router server yet.
8349 Some changes to NAMES definition in SILC protocol specification.
8351 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8353 * Implemented LEAVE command on client and server.
8355 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8356 again. This change was made to the protocol as well. Server
8357 should not violate the protocol specification anymore.
8359 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8362 was tested. SOCKS4 was not but should work anyway.
