121 that it is used to send error notifys if error occurs during
122 some SILC packet processing, except commands. The error
123 types are same as for command reply types. Defined that
124 if private message is sent to unknown Client ID the error
125 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.

133 The <Requested Attributes> (defined in a separate document)
134 can be used to request additional information about user
135 not returned by standard WHOIS command. Defined that server
136 can send WHOIS command directly to client. Client provides
137 the requested attributes to the server. Updated the protocol
138 specs. Protocol TODO #4. Implementation is not done yet

168 another command may attach to the same pending command reply
169 without requiring to resolve the same entry again. Added
170 support for adding multiple pending commands for one
171 command idenfier. Affected files lib/silcclient/command.[ch],
172 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

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

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

338 need the SilcSocketConnection which should not be visible
339 to application. Affected files are lib/silcclient/client.c
340 and lib/silcclient/silcclient.h.
342 * Rewrote the text for Private Message Key Payload in the
343 protocol specification. Protocol TODO #11.

362 the `notify' client operation.
364 * Fixed the Max Argument fields that had too large value set
365 in the protocol specs. Protocol TODO #14.
367 * Added the LEAVE command reply to return the ID of parted
368 channel. Updated protocol specs and implemented it to the
369 client and server. Protocol TODO #15. Affected files are
370 silcd/command.c, lib/silcclient/command_reply.c. The channel
371 entry is now returned to application in the `command_reply'

381 file is silcd/command.c.
383 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
384 generic reply to a generic request (REQUEST flag), and
385 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
386 way. A draft-riikonen-silc-flags-payloads-00.txt is written
387 to define the payload for DATA flag. Added the flags to
388 the implementation. Protocol TODO #9. Affected file is

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

467 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
469 * Changed the silc_get_username and silc_get_real_name to
470 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
472 * Fixed the Irssi SILC Client to use the silc_get_username and
473 silc_get_real_name insted of glib routines since the glib
474 routines only corrupt stack. Fixes the Irssi SILC to work in
475 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
477 * Fixed the Irssi to not use g_get_home_dir since it crashes
478 or returns garbage on cygwin and corrupts stack. Added function
479 get_home_dir to Irssi routines. Affected files are
480 irssi/src/core/misc.[ch] and irssi/src/core/core.c.

486 SilcPacketContext structure.
488 Affected files lib/silcsftp/sftp_fs_memory.c,
489 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
491 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
493 * And yet again reverted back the config thing since Johnny
494 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
497 * Fixed memory leaks from config object. Affected files are
498 silcd/serverconfig.[ch].
500 * Added support for adding new connections to the server in rehash.
501 After rehash they take effect.
503 Added support for changing the maximum allowed connections in
504 rehash. The number can grow but going smaller is not supported.
506 Added function silc_server_num_sockets_by_remote to the
507 silcd/server_util.[ch].
509 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
511 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
513 * Added preliminary checking during config parsing for a valid
514 public/private key and removed further checks in the code.
515 Affected files are silcd/serverconfig.[ch], server.c.
517 * Moved functions silc_server_drop() and silc_server_daemonise()
518 from server.c to silcd.c since they are stricly related to
519 the application activity.
521 * Reverted a small part of the automatic ref/unref since
522 it caused a double unref in some situations. Affected
523 files are silcd/silcd.[ch], server.c, serverconfig.c.
525 * Added some .cvsignore files in the lib directory.
527 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
529 * Fixed silc_net_gethostbyaddr to correctly resolve by
530 address. Affected file lib/silcutil/silcnet.c.
532 * Fixed the notify relaying to client. The HMAC to be used
533 with relayed packets ws wrong and caused decryption failure
534 at the client end. Affected file is silcd/packet_receive.c.
536 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
538 * Created new branch silc_protocol_1_0_branch.
540 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
542 * Changed the silc_server_config_* routines to be SilcServer
543 independent. They are now officially application specific code
544 and not part of generic server implementation. Affected files
545 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
547 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
549 * Added automatic referencing of config context in the
550 silc_server_config_alloc, and automatic unreferencing in the
551 silc_server_config_destroy. Affected files are
552 silcd/serverconfig.[ch], silcd/silcd.c.
554 * Fixed the silc_log_quick handling in the logging routines.
555 It didn't log quickly when it was TRUE. Affected file is
556 lib/silcutil/silclog.c. Also the flush delay was set even
557 if it was 0 in config file. Affected file is
558 silcd/serverconfig.c.
560 * Added support for changing key pair of the server in rehash.
561 Affected file silcd/server.c.
563 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
565 * Fixed the TOPIC_SET notify to not cras. It changed the topic
566 too early, before getting the channel entry. Affected file
567 is silcd/packet_receive.c.
569 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
571 * Added functions silc_server_config_[ref/unref], these are used
572 to prevent that the config object is destroyed.
574 No longer directly affect global variables silc_log_quick and
575 silc_log_delay, they are first cached inside the config object
576 and then applied with silc_server_config_setlogfiles().
578 silc_server_config_set_defaults() is now internal to
579 serverconfig.c, there are no reasons to show this internal stuff
582 Affected files are silcd/serverconfig.[ch].
584 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
585 fprintf's to stderr, since some code may be executed again after
586 the server went into the background. Affected files are
589 * Added rehash support. Added function silc_server_rehash() that
590 will perform all the basic tasks of the rehashing procedure.
592 * Added command line option `-x, --hexdump'. This will enable the
593 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
594 The option `--hexdump' implies `--debug'.
596 * Fixed a bad bug in the logging APIs (silcutil library) where
597 the application would crash after calling silc_log_reset_all().
599 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
601 * Fixed the KICKED notify handling in client library to
602 correctly remove the channel and all entries from the
603 channel when I was kicked. This bug crashed the client.
605 Fixed yet another but in KICKED notify handling to remove
606 the kicked client correctly from the channel.
608 Affected file is lib/silcclient/client_notify.c.
610 * Fixed a minor bug in looking up correct client entry
611 in KICKED notify in server. Affected file is
612 silcd/packet_receive.c.
614 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
615 sources correctly to distribution. Fixes --with-gmp option.
617 * Removed the manual rehashing from ID Cache, and changed it
618 to use the SILC Hash Table's auto rehash feature. Affected
619 file is lib/silccore/silcidcache.c.
621 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
623 * Fixed a bug in the silc_client_nickname_format function that
624 handles the multiple same nickname formatting. Two clients
625 with same nickname caused problems after the first one left
626 and rejoined. It didn't format the nickname correctly.
627 Affected file is lib/silcclient/idlist.c.
629 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
631 * Don't change the topic if olod topic is same as new one.
632 Affected file is silcd/packet_receive.c.
634 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Added cross-reference support to the SILC Documentation
637 generator. All types across all HTML files are now cross-
638 referenced. Affected files util/robodoc/generator.c and
639 scripts/silcdoc/silcdoc.
641 * Added file lib/silcutil/silctypes.h to include all the
642 arithmetic type definitions and some macros. Removed
643 includes/bitmove.h and moved macros to silctypes.h.
645 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
647 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
649 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
651 * Added `type' argument to silc_id_payload_parse_id function which
652 now returns the type of the ID to the sent pointer. Affected
653 file is lib/silccore/silcid.[ch].
655 * Added check for CMODE_CHANGE notify type that mode change is
656 allowed by the sender. Affected file silcd/packet_receive.c.
658 * Added check for CUMODE_CHANGE notify type that mode change is
659 allowed by the sender. Affected file silcd/packet_receive.c.
660 Added the ID type as CUMODE_CHANGE notify type as argument
661 to the `notify' client operation. Affected files are
662 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
664 * Added function silc_client_add_server to the client library.
665 Added support for resolving also channel and server info when
666 received unknown entity in notify packet. Affected files are
667 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
669 * Added function silc_command_get_status to return the command
670 status from the command reply's argument payload. Affected files
671 are lib/silccore/silccommand.[ch].
673 * Added check for KICKED notify type that the kicking is
674 allowed by the client. Affected file silcd/packet_receive.c.
676 * Created function silc_get_input which can be used to get input
677 (echo on or off) from user on command line. Affected files are
678 lib/silcutil/silcutil.[ch].
680 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
682 * Optimized silc_server_packet_relay_to_channel function.
683 Added new function silc_channel_message_payload_encrypt which
684 can be called directly if channel message payload needs to
685 be encrypted and is already encoded (no need to call _encode
686 function). Packet relaying is now done by router without any
687 extra memory allocations. Affected files are
688 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
691 * Fixed the INVITE notify handling. It took wrong arguments
692 as invite list and invite delete. Affected file is
693 silcd/packet_receive.c.
695 * Added check for TOPIC_SET notify type that the topic change is
696 allowed by the client. Affected file silcd/packet_receive.c.
698 * Added check for INVITE notify type that inviting is allowed by
699 the client. Affected file silcd/packet_receive.c.
701 * Changed the silc_server_client_on_channel to return the
702 SilcChannelClientEntry as well. Moved the function
703 silc_server_check_cmode_rights to server_util.[ch].
704 Affected files are silcd/server_util.[ch], silcd/command.c.
706 * Added function silc_server_check_umode_rights to check whether
707 changing client's user mode is allowed. Added check for
708 UMODE_CHANGE notify type that the umode change is allowed
709 by the client. Affected files are silcd/server_util.[ch],
710 silcd/packet_receive.c and silcd/command.c.
712 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
714 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
715 ID length. It ignored that ID can be IPv6 based as well.
716 Affected file lib/silccore/silcpacket.h.
718 * Fixed the silc_id_id2str and silc_id_str2id to take the
719 IPv6 address offset's into consideration. Affecte file is
720 lib/silccore/silcid.c.
722 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Fixed the internal Unix scheduler functions to check for
725 NULL context they may receive. The affected file is
726 lib/silcutil/unix/silcunixschedule.c.
728 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
730 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
731 can specify different directory with --home command line
732 parameter. Affected files irssi/src/silc/core/client_ops.c,
735 * SILC-specific commands aren't now executed if the active server
736 isn't of SILC-type, so there won't be problems with having
737 IRC and SILC protocol support in same client. Affected files
738 irssi/src/silc/core/silc-channels.c, silc-servers.c,
741 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
743 * Improved the signal support in SILC Schedule. Added new
744 function silc_schedule_signal_call which is used by application
745 to mark a signal to be called. It is now safe to perform
746 any kind of tasks in signal callbacks since it is guaranteed
747 that the application specified signal callback is called
748 after the signal is over. Affected files are
749 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
751 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Added `name' field to SilcChannelPrivateKey to represent
754 application given name for the key. Moved also the context from
755 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
756 Added the `name' argument also to the function
757 silc_client_add_channel_private_key.
759 Added function silc_client_current_channel_private_key to set the
760 current channel private key in use.
762 Added "change" command to KEY command which can be used to change
763 the current channel private key. Bound the command also to
766 Also affected files lib/silcclient/client_channel.c,
767 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
769 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
771 * Added silc_rng_get_byte_fast function in to the
772 lib/silccrypt/silcrng.[ch].
774 * Changed the interface of silc_packet_assemble and the
775 silc_packet_send_prepare. If silc_packet_assmble is now
776 called the application does not call silc_packet_send_prepare
777 because the library will call it automatically. These
778 interfaces now also return a reference to the outgoing buffer
779 which includes the assembled packet, which the application can
780 use to encrypt the packet.
782 Affected files are lib/silccore/silcpacket.[ch],
783 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
784 silcd/packet_send.c, server_backup.c and packet_receive.c.
786 * Fixed a packet sending bug on very high load, where outgoing
787 packet queue wasn't handled correctly and packets got corrupted.
788 Affected files are lib/silcutil/*/silc*sockconn.c,
789 lib/silcclient/client.c and silcd/server.c.
791 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Added macro SILC_PACKET_DATALEN which can be used during
794 packet assembling to check whether the data to be added to
795 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
796 len is truncated until it fits it.
798 Added checks for maximum length of channel message payload and
799 private message payload also.
801 Added checks for maximum packet length in server and in
804 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
805 lib/silcclient/client.c, lib/silccore/silcchannel.c and
806 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
807 lib/silcclient/client_prvmsg.c.
809 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
811 * Added silc_server_packet_queue_purge call to the
812 silc_server_disconnect_remote to assure that all data in the
813 queue before disconnecting is sent to the network. Affected
816 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
818 * Added the deleting of server's own ID cache entry to the
819 silc_server_free function. Free also everything else that
820 has been allocated in silc_server_init. The affected file
823 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
825 * Added functions silc_parse_version_string, silc_version_to_num,
826 and silc_ske_parse_version to parse SILC protocol style version
827 strings. Affected files lib/silcutil/silcutil.[ch] and
828 lib/silcske/silcske.[ch].
830 * Added new configuration params: version_protocol, version_software
831 and version_software_vendor to specify what version the remote
832 host must at least be to be able to connect to server. The vendor
833 string can be regex matched too. Added new function
834 silc_server_connection_allowed to check maximum number of allowed
835 connections, and allowed versions for incoming connections.
836 Affected files are silcd/server.c, server_util.[ch] and
839 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
841 * Added preliminary support for signals in scheduler. The
842 signals we care about are now blocked always when the scheduler
843 is locked. This way we can synchronise the use of signal with
844 scheduler. It is guaranteed that when signal occurs the scheduler
845 is not locked, and thus new tasks can be safely added to the
848 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
849 to silc_schedule_internal_init and silc_schedule_internal_uninit.
850 Added new platform specific routines
851 silc_schedule_internal_signals_[un]block and
852 silc_schedule_internal_signal_[un]register.
854 Added new functions to SILC Schedule API:
855 silc_schedule_signal_[un]register. Each signal that application
856 is going to use should be registered to the scheduler.
858 Affected files are lib/silcutil/silcschedule.[ch],
859 lib/silcutil/*/silc*schedule.c.
861 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
863 * Check for unauthenticated client and server in the
864 silc_server_new_client and silc_server_new_server functions.
865 Affected file silcd/packet_receive.c.
867 * Added function silc_string_is_ascii to check whether given
868 string is 7-bit ASCII string. Affected files are
869 lib/silcutil/silcutil.[ch].
871 * Added function silc_id_is_valid_server_id into the
872 silcd/serverid.c and added checking for valid Server ID's in
873 silc_server_new_server. The Server ID must always be based
874 on the server's public IP address.
876 * Added logging of DISCONNECT packet message in the server.
877 Affected file silcd/server.c.
879 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
881 * Changed all library interfaces that use Global RNG to also
882 accept SilcRng as argument. Affected files are
883 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
884 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
885 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
886 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
889 * Added function silc_pkcs_generate_key to the
890 lib/silccrypt/silcpkcs.[ch] for applications so that they
891 don't need to do pkcs->pkcs->init calls anymore.
893 * Remove SilcSocketConnection from the SFTP API since it really
894 wasn't needed there. The application has the information
895 saved in its contexts anyway and the SFTP layer doesn't need
896 know about it. Affected files lib/silcsft/silcsftp.h and
897 lib/silcsftp/sftp_[server/client].c.
899 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
900 The SilcSimContext is not SilcSim.
902 * Fixed possible buffer overflows in silc_id_render in the
903 lib/silcutil/silcutil.c.
905 * On EPOC the global crypto module lists are not used at all
906 in the crypto library. Added support for using the constant
907 algorithm list on EPOC. Affected files are
908 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
911 * Fixed the handling of third parameter of KICKED notify, since
912 it was mistakenly updated to SILC Protocol 1.0 even though it
913 is to be included in 1.1. Since it is not in 1.0 it is not
914 mandatory, and this fix now handles it only if it is provided,
915 and it is not error if it is not provided. Affected file
916 lib/silcclient/client_notify.c.
918 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
921 client. Affected file irssi/src/silc/core/client_ops.c.
923 * Merged with Irssi 0.8.4 from irssi.org CVS.
925 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
927 * Check for valid socket connection in client entries before
928 sending any messages. Fixes a crash, but doesn't fix some
929 other underlaying bug that is lurking there. Affected
930 file silcd/packet_send.c.
932 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
934 * $usermode, $cumode and $cumode_space expandos shouldn't do
935 anything with non-SILC server records. Affected file
936 irssi/src/silc/core/silc-expandos.c
938 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
940 * Fixed the silc_net_check_[host/local]_by_sock to support
941 IPv6 bound sockets as well. Now they can return IPv6 addresses
942 as well. Affected file lib/silcutil/silcnet.c.
944 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
945 Affected lib/silcutil/unix/silcunixnet.c.
947 * Fixed ID rendering (at least on some platforms, not NetBSD)
948 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
950 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Added silc_hash_public_key and silc_hash_public_key_compare
953 functions to be used with SilcHashTable. They can be used to
954 hash public keys and compare public keys in hash table. Affected
955 file lib/silcutil/silcutil.[ch].
957 * Added support for specifying multiple public keys for Client
958 connection section in server configuration file. This makes it
959 possible to accept multiple public keys from same host, or to
960 make a section that accepts any incoming host, and have the
961 accepted public keys listed in the section.
963 Added functions silc_sever_[find/get]_public_key, added the
964 support for this actually to all connection sections but only
965 the Client section is currently allowed to specify multiple
968 Affected files are silcd/server.c, server_internal.h,
969 command.c, protocol.c, server_util.[ch], packet_receive.c.
971 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
973 * Merged Irssi 0.8.2 from irssi.org CVS.
975 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
977 * If silc_debug is TRUE, also output standard logging messages
978 to stderr with the debug output.
980 Made silc_log_reset_all() flushing all channels before returning.
981 Also fixed some documentation typos.
983 Affected files are lib/silcutil/silclog.[ch].
985 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Fixed the server to check correctly the amount of connections
988 from single host, by checking also the type of the connection.
989 Fixed also the comparison of number of connections and number
990 of allowed connections. Affected files are silcd/server.c,
993 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Fixed the USERS command reply to save the user's mode on the
996 channel as well. Fixed JOIN command reply to check whether a
997 client is on channel already and not join it twice. Affected
998 file lib/silcclient/command_reply.c.
1000 * Added new file silc-expandos.c into irssi/silc/core/ to return
1001 various stuff for various signal for the statusbar etc. updating.
1002 Now Irssi SILC client prints channel user modes etc. on the
1005 * The user mode (like server/router operator changes) is now shown
1006 on the Irssi SILC client's statusbar. The affected files are
1007 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1009 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1011 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1012 to SILC_SCHEDULE_[UN]LOCK macros.
1014 * Added more error printing to logs in server code. Affected
1015 files silcd/server.c and silcd/protocol.c.
1017 * Fixed -S option parsing in Irssi SILC Client. Affected file
1018 irssi/src/silc/core/silc-core.c.
1020 * Added silc_buffer_alloc_size function. Affected file is
1021 lib/silcutil/silcbuffer.h.
1023 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1025 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1026 constants. Affected files in

1072 application does not need to define them. Affected file
1073 includes/silcincludes.h.
1075 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1076 old name went against naming convention. Applications now
1077 include "silcclient.h" instead of "clientlibincludes.h".
1078 Removed includes/clientlibincludes.h, it is redundant now.
1080 * Renamed includes/version.h to silcversion.h.
1082 * Added really preliminary support for OS/2 into the util
1083 library. Only thread & mutex API is implemented, others
1084 are still to be implemented. Created the lib/silcutil/os2/
1085 directory. Created also file includes/silcos2.h.

1118 * Added `user_count' to the SilcChannelEntry which now tells the
1119 number of users on the channel. The user count is now saved
1120 in normal server of global channels as well. Affected files
1121 silcd/server.c, idlist.h, packet_receive.c and command.c.
1123 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1124 include file utility functions.

1127 instead of calling directly OS routines.
1129 * Fixed NICK change printing in Irssi SILC Client. Fixed
1130 KICKED notify printing in Irssi SILC Client. Affected file
1131 irssi/src/silc/core/client_ops.c.

1140 the SKE interface a bit.
1142 * Fixed padding problem in PKCS#1. The padding was not actually
1143 random since the random number generator was used incorrectly.
1144 This security bug affects only when encrypting with PKCS#1, and
1145 it is not currently used at all in SILC. SILC only use signing
1146 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1206 is now done in silc_core_init() which also fixes autoconnecting
1209 Affected files irssi/src/silc/core/silc-core.c,
1210 irssi/src/fe-text/silc.c.
1212 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1214 * Added new configuration options and blocks:
1215 keepalive_secs, reconnect_count, reconnect_interval,
1216 reconnect_interval_max, reconnect_keep_trying and
1217 require_reverser_lookup. Added ConnectionParam block, and
1218 implemented the connection parameters when connecting as
1219 initiator and when accepting connections as responder.

1231 the connection configuration object from the SilcServerConnection
1232 object instead of finding it during the connecting phase.
1233 Added the configuration object to SilcServerConnection struct.
1234 Affected files silcd/server_internal.h, server.c.
1236 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1238 * Add the client on channel after it was resolved at the
1239 channel message receiving, and it was not already on the
1240 channel. Affected file lib/silcclient/client_channel.c.
1242 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1258 authentication to be set at the same time.
1260 Added `prefer_passphrase_auth' setting in config file which
1261 can be used to set to prefer passwd auth if both passwd and
1262 public key is set. If not set, public key is preferred.
1263 This has effect only when being initiator (responder will try
1266 Added support for authentication with passphrase and public key
1267 at the same time. The passphrase is tried first always since
1268 it is faster to check.
1270 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1272 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1318 * Fixed the file transfer's key agreement payload to include
1319 zero port also if the hostname is NULL because it could not
1322 Call file transfer monitor callback now also if error occurs
1323 during key agreement protocol.
1325 Changed the silc_client_file_send interface to return the
1326 SilcClientFileError instead of session id. The session ID
1327 is returned into pointer provided as argument.
1329 Check that the file exists locally before sending the
1330 file transfer request at all.
1332 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1334 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1396 users list to SilcHashTable. The affected files are
1397 lib/silcclient/idlist.[ch].
1399 * Fixed a bug in hash table tarversing. While the hash table
1400 is traversed with SilcHashTableList the table must not be
1401 rehashed. It is now guaranteed that auto rehashable tables
1402 are not rehashed while tarversing the list. Also defined that
1403 silc_hash_table_rehash must not be called while tarversing
1404 the table. Added function silc_hash_table_list_reset that must
1405 be called after the tarversing is over. The affected files are
1406 lib/silcutil/silchashtable.[ch].
1408 * Changed all hash table traversing to call the new
1409 silc_hash_table_list_reset in server and in client library.
1411 * Added function silc_client_on_channel to return the
1412 SilcChannelUser entry if the specified client entry is joined
1413 on the specified channel. This is exported to application as
1414 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1423 lists correctly. Affected file silcd/command.c.
1425 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1427 * When sending JOIN command to router for processing the
1428 sender's old command identifier was not saved back to the
1429 sender's command context, fixed now. The affected file is
1432 * Create the key in JOIN command of the router did not return
1433 the channel key, added check for this. Affected file is
1436 * Fixed a channel ID update bug in JOIN command reply. Do
1437 not directly upgrade the ID but call the function
1438 silc_idlist_replace_channel_id if the ID was changed.
1439 Affected file silcd/command_reply.c.
1441 * Fixed memory leaks from command calling if it would fail.

1554 lib/silcclient/client.c.
1556 * The server's public key is now saved using the IP address
1557 of the server and not the servername for the filename.
1558 The hostname public key filename is checked as an fall back
1559 method if the IP address based filename is not found.
1561 Fixed the GETKEY command to save the fetched server key
1562 in correct filename.
1564 Print the remote server's hostname now when new key is
1565 received during connection process. Affected file is
1566 irssi/src/silc/core/client_ops.c.
1568 * Return always our own public key to the client if it asks
1569 for it with GETKEY command. Affected file silcd/command.c.
1571 * Removed the use_auto_addr variable from default config
1572 file since it was in wrong section. Affected file is
1575 * Fixed TOPIC_CHANGE notification to not route it when it
1576 was sent using silc_server_send_notify_to_channel function.
1577 Affected file silcd/command.c.
1579 * Fixed silc_server_send_notify_kicked to send the kicker's
1580 Client ID also, it was missing. Affected files are
1581 silcd/command.c, silcd/packet_send.[ch].
1583 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1585 * Do not save client history information in SERVER_SIGNOFF.
1586 Fixes the bug in normal server that it does not detect
1587 the client becoming valid after the server becomes back
1588 online. Affected file silcd/server_util.c.
1590 * Added `sock_error' field into the SilcSocketConnection
1591 context. When error occurs during socket operation (read
1592 or write) the error is saved. Added also new function
1593 silc_socket_get_error to return human readable socket error
1594 message. Affected files are lib/silcutil/silcsockconn.[ch],
1595 lib/silcutil/unix/silcunixsockconn.c, and
1596 lib/silcutil/win32/silcwin32sockconn.c.
1598 * The server now prints the socket error message in the
1599 signoff for client. Affected file silcd/server.c.
1601 * Fixed the `created' channel information sending from router
1602 to server in JOIN command. Checks now whether the channel
1603 really was created or not and set it according that.
1605 Fixed the JOIN command to use the client entry's current
1606 ID during the joining procedure instead of the one it sent
1607 in the command (it is checked though), since it can change
1608 between the packet processing and command processing, and
1609 would just case unnecessary pain in the client end. Affected
1610 file silcd/command.c.
1612 * Fixed a channel key payload sending to use correct channel
1613 ID when the server was forced to change the channel's ID by
1614 router. Router sent the key payload with the old Channel ID.
1615 Affected file silcd/packet_receive.c.
1617 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1619 * Call silc_server_save_channel_key only if the key payload
1620 was provided in the JOIN command's command reply. Affected
1621 file silcd/command_reply.c.
1623 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Fixed silc_mp_sizeinbase to return the value correctly with
1626 MPI. Affected file lib/silcmath/mp_mpi.c.
1628 * Fixed the stop_server signal to correctly stop the scheduler
1629 and gracefully stop the server when SIGTERM or SIGINT signals
1630 are received. Affected file silcd/silcd.c.
1632 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1634 * Simple handling of TERM and HUP signals. Also added some log
1635 flushing call around. Affected file is
1638 * Fixed small bugs in silclog.c. Now buffering output will take
1639 effect after 10 seconds since startup: This will ensure that
1640 no important startup messages are lost. Also output redirection
1641 will preserve original format ([Date] [Type] message).
1642 Affected file is lib/silcutil/silclog.c.
1644 * Added two options to the config file, in the logging section:
1645 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1646 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1648 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1650 * Do not print the warning about log files not being initialized
1651 more than once to avoid excess logging. Affected file is
1652 lib/silcutil/silclog.c.
1654 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1655 the SIM copying in make install in Makefile.am.pre.
1657 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1659 * Rewritten silclog APIs. Globally interesting changes follows:
1660 silc_log_set_files() changed to silc_log_set_file().
1661 silc_log_set_callbacks() changed to silc_log_set_callback().
1662 ROBOdoc documented silclog header file.
1663 SilcLogCb now returns bool to wether inihibit the default
1664 handler or not (to keep the old behaviour return always TRUE).
1665 The new APIs should also fix the problem of the
1666 silcd_error.log file that was written in the current directory.
1669 Log files streams will remain opened after silc_log_set_file()
1670 call, means less CPU usage notably on high traffic servers.
1671 File streams are now full buffered, and flushed to the disk
1672 every 5 minutes, lesses HD activity and CPU usage.
1673 Messages can be redirected, allowing admins to configure
1674 one single logfile for all server messages.
1675 the silc_log_quick global variable to activate fast-logging.
1676 Affected files lib/silcutil/silclog.[ch]
1678 * Changed some code to conform new silclog APIs. Affected
1679 files are doc/example_silcd.conf.in, silcd/server.c
1680 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1683 * Fixed a memory leak that could occur in some situations.
1684 Affected file silcd/serverconfig.c.
1686 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1688 * Added the silc_client_del_client to remove the client from
1689 all channels as well. Affected file lib/silcclient/idlist.c.
1691 * Fixed the client library to correctly remove the client
1692 from all channels when the client entry is being destroyed.
1693 Affected file lib/silcclient/client_notify.c, command.c.
1695 * Added auto-nicking support to the client library. If the
1696 applicatio now sets client->nickname it will be sent to the
1697 server after connecting by the library. This way for example
1698 SILCNICK (or IRCNICK) environment variables will have effect
1699 and always change the nickname automatically to whatever
1700 it is wanted. Affected file lib/silcclient/client.[ch].
1702 * Renamed silc_server_command_bad_chars to the
1703 silc_server_name_bad_chars and moved it to the
1704 silcd/server_util.[ch]. Added also new function
1705 silc_server_name_modify_bad to return nickname that
1706 includes bad characters as new nickname without those
1707 bad characters. This check and modify is now used in
1708 silc_server_new_client when the username is initially set
1709 as nickname, so it must be checked to be valid nickname.
1710 Affected file silcd/packet_receive.c.
1712 * The nickname length is now taken from the packet for real
1713 and not trusted to strlen() since it clearly can return
1714 wrong length for nickname including bad characters. This
1715 also applies to channel names. Affected file silcd/command.c.
1717 * Removed the lib/silcsilm/modules directory. Modules are now
1718 compiled into the lib/silcsim. Fixed the copying of the
1719 modules to follow symbolic links in Makefile.am.pre.
1721 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1723 * Fixed silc_string_regexify list creation. Fixes bugs with
1724 BAN and INVITE commands in server. The affected file is
1725 lib/silcutil/unix/silcunixutil.c.
1727 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Removed the command destructor entirely from the server's
1730 command and command reply routines. It is not needed, and
1731 its usage was buggy and caused crashes. Affected files are
1732 silcd/command[_reply].[ch].
1734 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * Cancel protocol and NULL sock->protocol if timeout
1737 occurred during protocol. Affected file silcd/server.c.
1739 * Cancel protocol timeouts always before calling the final
1740 callback, to assure that after final callback is called
1741 no other state will be called for the protocol anymore.
1742 Affected file silcd/protocol.c.
1744 * Print error log if incoming connection configuration could
1745 not be found. Affected file silcd/server.c.
1747 * Fixed JOIN command to correctly save the founder mode
1748 to the client on normal SILC server, when the channel
1749 was created by the router. Affected file silcd/command.c.
1751 * Fixed LIST command (hopefully) to send correct reply
1752 packets. Affected file silcd/command.c.
1754 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1756 * The silc_packet_receive_process now returns FALSE if the
1757 read data was invalid packet, and TRUE if it was ok.
1759 The server now checks that if unauthenticated connection
1760 sends data and its processing fails the server will close
1761 the connection since it could be a malicious flooder.
1763 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1765 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1767 * Make sure the warning about error opening a log file is
1768 printed only once and not everytime it fails (produces
1769 too much useless log). Affected file lib/silcutil/silclog.c.
1771 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1773 * Made the silc_server_daemonise() function more readable.
1774 Affected file silcd/server.c.
1776 * Pid file is now optional, the user may comment it out from
1777 the config file. Removed define SILC_SERVER_PID_FILE, we
1778 don't need a default any longer. Affected file
1779 configure.in.pre, lib/Makefile.am.pre.
1781 * Make some use of the pid file. The server now dies at startup
1782 if it detects a valid pid file on his path. The server would
1783 die anyway in this circumstance, because of the bind() failure.
1784 Affected file silcd/silcd.c.
1786 * No longer compiling lib/dotconf.
1788 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Fixed JOIN command parsing not to crash. Affected file
1791 lib/silcclient/command.c.
1793 * Fied the NICK_CHANGE notify to add the new client entry
1794 even it is resolved. This removes an <[unknown]> nick
1795 thingy bug in the client. Affected file is
1796 lib/silcclient/client_notify.c.
1798 * Do not try to allocate 0 bytes (efence does not like it)
1799 in lib/silccore/silccomand.c when encoding payload.
1801 * Do not take IRCNICK as nickname in Irssi SILC client since
1802 it is not possible to set nickname before hand connecting
1803 the server (TODO has an entry about adding auto-nicking
1806 * Changed the silc_server_command_pending to check whether
1807 there already exists an pending entry with the specified
1808 command, command identifier and pending callback. This is
1809 to fix IDENTIFY and WHOIS related crashes that may register
1810 multiple pending commands with same identifier. Affected
1811 file silcd/command.c.
1813 * Fixed the server to reconnect to the router even if it
1814 was already reconnecting and EOF was received. This to
1815 fix a possibility that the server wouldn't ever try to
1816 auto-reconnect to the router. Affected file silcd/server.c.
1818 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Fixed the server's password authentication to use the
1821 length of the locally saved password, and not the one
1822 sent in the packet. Affected file silcd/protocol.c.
1824 * Fixed same password authentication problem in the
1825 Authentication Payload handling routines in
1826 lib/silccore/silcauth.c.
1828 * Yet another password authentication problem fixed with
1829 channel password handling in silcd/command.c.
1831 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1833 * If first character of string in silc_parse_userfqdn is '@'
1834 then do not parse it. Affected file is
1835 lib/silcutil/silcutil.c.
1837 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1839 * Fixed minor bug in IDENTIFY command reply sending, which
1840 caused various weird problems during JOIN when it was
1841 resolving names for users. Affected file silcd/command.c.
1843 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Fixed the IDENTIFY command reply sending to chech better valid
1846 clients. It was possible to send incomplete list of replies.
1847 Affected file silcd/command.c.
1849 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1851 * Added silc_client_command[s]_[un]register functions now to
1852 dynamically register the commands in client library. Removed
1853 the static table of commands. This allows the client library
1854 to call commands without causing the application to know about
1855 what commands library has called.
1857 Removed the INFO command reply kludge to detect when the command
1858 was called by library. Now library use its own command reply
1859 function for INFO command.
1861 Added function silc_client_command_call to call a command.
1862 Application can use it to call command, not access the structure
1865 Now all commands that are sent by the client library (not
1866 explicitly sent by application) use own command reply functions.
1868 Affected files around lib/silcclient/ and in
1869 irssi/src/silc/core/.
1871 * Fixed the WHOIS command reply sending to chech better valid
1872 clients. It was possible to send incomplete list of replies.
1874 Fixed the WHOIS and IDENTIFY to send the request to router
1875 if normal server did not do it and did not find any results.
1877 Affected file silcd/command.c.
1879 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1881 * Moved the internal data from SilcClient context into its
1882 own file, not accesible to application. Affected files
1883 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1884 and other files in client library.
1886 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1888 * Added doc/examples installation target in Makefile.am.pre.
1891 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1894 commands the found client entry will be removed from the
1895 cache, after notifying application about the error. Affected
1896 file lib/silcclient/command_reply.c.
1898 * Changed the /MSG to check for exact nickname user gave, and
1899 not let `nick' match `nick@host' if it is only one found. Now,
1900 user must type the exact nickname (like nick@host2) even if
1901 there are no more than one same nicks found. This is to avoid
1902 a possibility of sending nickname to wrong nickname since
1903 `nick' could match `nick@host'. Affected file is
1904 irssi/src/core/silc-servers.c.
1906 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1908 * Do not print "you are now server operator" or similar when
1909 giving /away command. Affected files are
1910 irssi/src/silc/core/client_ops.c, silc-servers.h.
1912 * Made the silc_server_command_pending_error_check to send
1913 the same command reply payload it received back to the
1914 original sender of the command. This way all arguments
1915 that was received by the server will be received by the
1916 client too. Affected file silcd/command.c.
1918 * Added the silc_idcache_add to return the created cache entry
1919 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1921 * Add global clients to expire if they are not on any channel.
1922 This is because normal server will never know if they signoff
1923 if they are not on any channel. The cache expiry will take
1924 case of these entries. This is done by normal servers only.
1925 The affected files are silcd/command_reply.c,
1926 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1928 * If server receives invalid ID notification for WHOIS or
1929 IDENTIFY and the ID exists in the lists, it is removed.
1930 Affected file silcd/command_reply.c.
1932 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1933 in client then client entry that it matches is searched and
1934 the nickname is printed on the screen for user. Affected
1935 file irssi/src/silc/core/client_ops.c.
1937 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Use cache entry expire time in the LIST command reply to
1940 purge old entries from the cache after the LIST command
1941 reply has been received. This way we don't have non-existent
1942 entries in the cache for too long. Affected file is
1943 silcd/command_reply.c.
1945 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1947 * If we are normal server, and we've not resolved client info
1948 in WHOIS or IDENTIFY from router, and it is global client,
1949 we'll check whether it is on some channel. If it is not
1950 then we cannot be sure about its validity and will resolve it
1951 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1952 file silcd/command.c.
1954 * Search channel by name (if possible) rather than by ID
1955 in IDENTIFY command's command reply. Affected file is
1956 silcd/command_reply.c.
1958 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1960 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1961 Updated specs and implemented it. Affected file silcd/command.c,
1962 silcd/packet_send.c and silcd/packet_receive.c.
1964 * Implemented the <founder auth> payload handling in the JOIN
1965 command. If provided all conditions for channel joining
1966 except requirement to provide correct passphrase can be
1967 overrided by the channel founder. Updated the protocol specs.
1968 Affected file silcd/command.c.
1970 Added support for founder auth in JOIN command in client
1971 library. Fixed the parsing of the JOIN command now to support
1972 all options as they should be. The affected file is
1973 lib/silcclient/command.c.
1975 * Optimized the WHOIS and IDENTIFY commands to send the request
1976 to router only if it includes nicknames or other names. If
1977 they include only IDs then check the local cache first before
1978 routing. Affected file is silcd/command.c.
1980 * Added channels topic announcements. Affected file is
1981 silcd/packet_receive.c and silcd/server.c.
1983 * Fixed the silc_server_send_notify_topic_set to really destine
1984 the packet to channel. Affected file silcd/packet_send.c.
1986 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1987 library. Affected file lib/silcclient/client_notify.c.
1989 * Added UMODE announcements. Affected file silcd/server.c.
1991 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1993 * Memory leak fixes in:
1995 lib/silcutil/silcsockconn.c
1996 lib/silcske/silcske.c
1997 lib/silcske/groups.c
1999 lib/silccrypt/silcpkcs.c
2000 lib/silccore/silccommand.c
2001 lib/silccore/silcidcache.c
2006 * ROBOdoc documented the lib/silcske/groups.h file and a
2007 bit changed the interface for better.
2009 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2011 * Update the client entry context in the ID cache after
2012 nick change. Affected file lib/silcclient/command.c.
2013 Fixes the CUMODE command when regaining founder privileges,
2014 and a little WHOIS problem.
2016 * Fixed silc_net_gethostbyname to correctly call the
2017 inet_ntop. Affected file lib/silcutil/silcnet.c.
2019 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2021 * Added IPv6 support checking to the configure.in.pre, added
2022 also --enable-ipv6 option to override the check. Affected
2023 file configure.in.pre.
2025 * The silc_thread_create now calls the start function
2026 directly if threads support is not compiled in. Removes
2027 ugly #ifdef's from generic code. Affected files are
2028 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2030 * Added silc_net_gethostby[name/addr]_async to asynchronously
2031 resolve. Affected files are lib/silcutil/silcnet.[ch].
2033 * Added support for rendering IPv6 based server, client and
2034 channel IDs. Affected file lib/silcutil/silcutil.c.
2036 * Added support for creating IPv6 based server IDs. Affected
2037 file is silcd/serverid.c.
2039 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2041 * Added silc_net_gethostby[addr/name] into the
2042 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2043 routines. Added silc_net_is_ip[4/6]. Affected file is
2044 lib/silcutil/unix/silcunixnet.c. All routines that take
2045 address as argument now supports both IPv4 and IPv6 addresses.
2047 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2049 * Fixed LIST command reply sending in server. Affected file
2052 * Server now sends the kicker's client ID in the KICK notify
2053 to the kicked client. Affected file silcd/command.c.
2055 * The client library now parses the kickers client ID and
2056 UI displays it. Affected files lib/silcclient/client_notify.c
2057 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2059 * Made all payload parsing function prototypes consistent.
2060 They all take now const unsigned char * and uint32 pair as
2061 the payload data instead of SilcBuffer. Changes all around
2062 the source tree. Other unsigned char* -> const unsigned char*
2063 changes around the tree as well.
2065 * Optimized SFTP client and server packet sending not to
2066 allocate new buffer for each packet but to recycle the
2067 first allocated buffer. Affected files are
2068 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2070 * Optimized the SFTP client to use SilcList instead of
2071 SilcDList for requests, because it is faster. Affected file
2072 is lib/silcsftp/sftp_client.c.
2074 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2075 into lib/silccore/silcid.[ch].
2077 Renamed silcpayload.[ch] into silcargument.[ch].
2079 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * If client entry is deleted with active key agreement
2082 session, abort the session.
2084 The silc_client_abort_key_agreement now calls the completion
2085 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2087 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2090 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2092 * Don't use __restrict in older GCC's. Affected file is
2093 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2095 * silc_net_localhost now attempts to reverse lookup the
2096 IP/hostname. Affected file lib/silcutil/silcnet.c.
2098 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2099 command. It can be used to gain founder privileges at
2100 the same time when joining the channel.
2102 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2103 kicker's client ID as well. Updated protocol specs.
2105 Defined that the server must send SILC_COMMAND_IDENTIFY
2106 command reply with error status to client who sent
2107 private message with invalid client ID.
2109 Updated the protocol specification.
2111 * Added silc_server_send_command_reply to send any
2112 command reply. Affected file silcd/packet_send.[ch].
2114 * Added silc_id_payload_encode_data to encode ID payload
2115 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2117 * The server now send IDENTIFY command reply with error
2118 status if client ID in private message is invalid. Affected
2119 file silcd/packet_receive.c.
2121 * Save the server key file with server's IP address in
2122 the filename instead of hostname. The affected file is
2123 irssi/src/silc/core/client_ops.c.
2125 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2130 * Added libtool support for compiling shared objects in
2131 lib/silcsim. Affected file configure.in.pre and
2132 lib/silcsim/Makefile.am. Original patch by cras.
2134 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2136 * Pid file configuration, and server's config file fixes
2137 patch by toma. Updated CREDITS file.
2139 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2141 * Fixed silc_client_channel_message to not try to decrypt
2142 the message twice if it resolved the destination client
2143 information. This could cause of dropping one channel
2144 message. Affected file lib/silcclient/client_channel.c.
2146 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2149 lib/silcclient/client.c. This function is used when the SILC
2150 Client is run under some other scheduler, or event loop or
2151 main loop. On GUI applications, for example this may be
2152 desired to used to run the client under the GUI application's
2153 main loop. Typically the GUI application would register an
2154 idle task that calls this function multiple times in a second
2155 to quickly process the SILC specific data.
2157 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2159 * Fixed silc_server_drop() for dropping the supplementary
2160 groups as well, this could cause a security hole on some
2163 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2165 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2168 * Write PID file after dropping privileges. Added -F option
2169 to run server on foreground. A patch by debolaz.
2170 Affected files silcd/server.c, silcd/silcd.c.
2172 * Fixed MOTD to return the MOTD file server name. Affected
2173 file silcd/command.c.
2175 * Added INFO command reply handling to the Irssi SILC Client.
2176 Affected file irssi/src/silc/core/client_ops.c.
2178 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Fixed the silc_idcache_list_* routines to really support
2181 the dynamic list. Fixes a crash. Affected file is
2182 lib/silccore/silcidcache.c.
2184 * Fixed the LIST command reply to really call LIST command's
2185 pending callbacks. Affected file silcd/command_reply.c.
2187 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Update conn->local_entry->nickname after giving NICK
2190 command. Affected file lib/silcclient/command.c.
2192 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2194 * Added the [pid] option to the silcd configuration file
2196 Affected files: serverconfig.[ch] and silcd.c
2198 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2200 * Save fingerprint in WHOIS command reply in server.
2201 Affected file silcd/command_reply.c.
2203 * Fixed NICK commands pending callback registration.
2204 Affected file lib/silcclient/command.c.
2206 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2208 * Use ++server->cmd_ident when sending commands in server,
2209 instead of random number. Affected file silcd/command.c.
2211 * Fixed GETKEY command reply to call actually GETKEY pending
2212 command callbacks. Affected file silcd/command_reply.c.
2214 * A bit stricter check for nicknames. Check for same nickname
2215 in NICK command also. Affected file silcd/command.c.
2217 * Do not call INFO command everytime client ID changes, only
2218 during first connecting. Affected file lib/silcclient/client.c.
2220 * Set the new nickname only after successful command reply for
2221 NICK command is returned by server. Affected file
2222 lib/silcclient/command.c.
2224 * Remove nicknames from nicklist during server_signoff notify.
2225 Should fix /NAMES bit more. The affected file is
2226 irssi/src/silc/core/silc-channels.c.
2228 * Added `fingerprint' field to the SilcIDListData in the
2229 silcd/idlist.h to hold the fingerprint of the client's
2232 Send the fingerprint of the client's public key in WHOIS
2235 Affected files silcd/command.c, and silcd/idlist.[ch].
2237 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2238 create fingerprint from given data.
2240 * Show the fingerprint of the client's public key in WHOIS.
2241 Affected files irssi/src/module-formats.[ch] and
2242 irssi/src/silc/core/client_ops.c.
2244 * Format the multiple same nicknames also during JOIN and
2245 NICK_CHANGE notifys. Affected file is
2246 lib/silcclient/client_notify.c.
2248 * Do not print error on screen for invalid private message
2249 payload since it can come if someone is sending private
2250 messages with wrong key. Affected file
2251 lib/silccore/silcprivate.c.
2253 * Fixed multiple concurrent /PING crash. Affected file
2254 lib/silcclient/command.c.
2256 * Changed the wrong ID encoding. All IP addresses must be
2257 in MSB first order in encoded format. They were encoded
2258 wrong and was in LSB format. Affected files are
2259 silcd/serverid.c, lib/silcutil/silcutil.c.
2261 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2263 * Call the `connect' client operation through the scheduler
2264 in case of error. Affected file lib/silcclient/client.c.
2266 * Call the `failure' client operation even if the error
2267 occurred locally during a protocol. Affected file is
2268 lib/silcclient/protocol.c.
2270 * Added support of sending LIST command to router from normal
2271 server. This way normal server can get list of all channels
2272 in the network too. Fixed the channel list sending in the
2273 server too. Affected files are silcd/command.c, and
2274 silcd/command_reply.[ch].
2276 * Added silc_server_update_channels_by_server and
2277 silc_server_remove_channels_by_server. They are used during
2278 disconnection of primary router and in backup router protocol.
2279 Affected file silcd/server_util.[ch], silcd/server.c and
2280 silcd/server_backup.c.
2282 * Fixed channel adding to global list in IDENTIFY command
2283 reply in server. Affected file silcd/command_reply.c.
2285 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * If the incoming packet type is REKEY or REKEY_DONE process
2288 that packet always synchronously. Fixes yet another MAC
2289 failed error on slow (dialup) connections. Affected file
2290 lib/silcclient/client.c and silcd/server.c.
2292 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Call check_version SKE callback for initiator too. Affected
2295 file lib/silcske/silcske.c.
2297 * Implemented fix for security hole found in the SKE that was
2298 fixed in the specification few days back; the initiator's
2299 public key is now added to the HASH value computation.
2300 Added backwards support for the old way of doing it too, for
2301 old clients and old servers. Affected file is
2302 lib/silcske/silcske.c.
2304 * Enabled mutual authentication by default in SKE. If initiator
2305 is not providing mutual authentication the responder will
2306 force it. This will provide the proof of posession of the
2307 private key for responder. The affected files are
2308 lib/silcclient/protocol.c and silcd/protocol.c.
2310 * Do not cache anymore the server's public key during SKE.
2311 We do mutual authentication so the proof of posession of
2312 private key is done, and if the server is authenticated in
2313 conn auth protocol with public key we must have the public
2314 key already. Affected file silcd/protocol.c.
2316 * Added new global debug variable: silc_debug_hexdump. If
2317 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2318 file lib/silcutil/silclog.[ch].
2320 * Fixed compilation warning due to char * -> const char *.
2321 Affected files lib/silcutil/silcnet.h, and
2322 lib/silccore/silcauth.[ch].
2324 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Fixed CMODE command when new channel key was created. If
2327 the creation failed the old key was removed. Next time giving
2328 same command would crash the server since the old key was
2329 freed already. Affected file silcd/command.c.
2331 * Fixed the silc_server_announce_get_channels to not crash
2332 on reconnect. Affected file silcd/server.c.
2334 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Added silc_log_set_debug_string function to set a regex
2337 string to match for debug output. Only the function names,
2338 or filenames matching the given debug string is actually
2339 printed. This way it is possible to filter out those debug
2340 strings that user is not interested in.
2342 Fixed a bug in silc_string_regexify.
2344 Affected files lib/silcutil/silclog.[ch], and
2345 lib/silcutil/unix/silcunixutil.c.
2347 * Changed the -d options in both server and Irssi SILC client
2348 to take the debug string as argument. Affected files
2349 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2351 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Added silc_hash_babbleprint to create a Bubble Babble
2354 Encoded fingerprint. The encoding is developed by Antti
2355 Huima (draft-huima-babble-01.txt), and it creates human
2356 readable strings out of binary data. Affected file
2357 lib/silccrypt/silchash.[ch].
2359 * Print the babble print now in addition of fingerprint as well
2360 in Irssi SILC client. Affected files are
2361 irssi/src/fe-common/silc/module-formats.[ch],
2362 irssi/src/fe-common/silc/core/client_ops.c.
2364 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Fixed a security problem found in SKE. The initiator's
2367 public key too is now added to the HASH hash value creation
2368 which is signed by the responder to create the SIGN value.
2369 This will prevent anyone in the middle to lie to the responder
2370 about the initiator's public key. If this is done now, the
2371 man in the middle will get caught. Updated the protocol
2374 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Better installation directory handling. Configure module
2377 paths and other paths automatically to example_silc* files
2378 in doc/. A patch by toma.
2380 * Fixed compiler warning from MPI library, and from SILC RNG.
2383 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2384 It can be configured with ./configure. A patch by toma.
2386 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2388 * Find correct make to use in prepare-clean. A patch by
2389 toma. Affected file prepare-clean.
2391 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2393 * Added irssi variables use_auto_addr, auto_bind_ip,
2394 auto_bind_port and auto_public_ip.
2396 * Changed the interface for silc_client_send_key_agreement
2397 in lib/silcclient/silcapi.h
2401 irssi/src/silc/core/silc-core.c
2403 lib/silcclient/silcapi.h
2404 irssi/src/silc/core/silc-channels.c
2405 lib/silcclient/client_keyagr.c
2408 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2410 * Added silc_pkcs_public_key_compare to compare two
2411 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2413 * Check that the client who set the founder mode on the
2414 channel is the same client that is giving the founder
2415 mode to itself. It is done by comparing the saved public
2416 key (it is saved even in the authentication is passphrase).
2417 Affected file silcd/command.c.
2419 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2421 * Do not process packet for disconnected socket connection.
2422 Affected file lib/silccore/silcpacket.c.
2424 * Process the DISCONNECT packet through scheduler in the
2425 client library. Affected file lib/silcclient/client.c.
2427 * Fixed the silc_client_packet_parse to not to increase
2428 the packet sequence number if the conn->sock and the
2429 current socket connection is not same. This can happen
2430 for example during key agreement when the conn includes
2431 multiple socket connections (listeners). Affected file
2432 lib/silcclient/client.c.
2434 * The sender of the file transfer request now provides also
2435 the pointer (listener) for the key exchange protocol. If
2436 the listener cannot be created then it sends empty key
2437 agreement and lets the receiver provide the listener.
2439 Added `local_ip' and `local_port' arguments to the
2440 silc_client_file_send. If they are provided they are used,
2441 if not then it will attempt to find local IP address, if
2442 not found or bind fails then the remote client will provide
2445 Affected files are lib/silcclient/client_ftp.c and
2446 lib/silcclient/silcapi.h.
2448 * Extended the FILE SEND command to support defining the
2449 local IP and port for key exchange listener. They are
2450 optional. Affected file irssi/src/silc/core/silc-servers.c.
2452 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Defined to WHOIS command reply the sending of fingerprint
2455 of the client's public key (if the proof of posession of the
2456 corresponding private key is verified by the server).
2457 Updated to the protocol specification.
2459 * Added support of receiving the client's public key's
2460 fingerprint in command reply in client library. Affected
2461 file is lib/silcclient/command_reply.c, and
2462 lib/silcclient/idlist.[ch].
2464 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Do not send over 128 chars long nickname to the server
2467 in NICK command. Affected file lib/silcclient/command.c.
2469 * Do not send over 256 chars long channel names to the server
2470 in JOIN command. Affected file lib/silcclient/command.c.
2472 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2474 * Assure that silc_server_close_connection cannot be called
2475 twice for same socket context. Affected file is
2478 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Send error message to application if opening file for
2481 writing during file transfer fails. Affected file is
2482 lib/silcclient/client_ftp.c.
2484 Remove all file transfer sessions for a client that we're
2485 removing from ID cache.
2487 Affected file is lib/silcclient/client_ftp.c.
2489 * Fixed silc_net_addr2bin to return correct address. Affected
2490 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2492 * Fixed file transfer session removing on signoff notify.
2493 Affected file irssi/src/silc/core/silc-servers.c.
2495 * Added the SilcClientFileError to be returned in the monitor
2496 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2497 Affected file lib/silcclient/silcapi.h.
2499 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2501 * Fixed a crash in silc_client_ftp_free_sessions and
2502 silc_client_ftp_session_free_client. Affected file
2503 lib/silcclient/client_ftp.c.
2505 * Added `disabled' field in the SilcChannelEntry in the server
2506 to indicate if the server entry is disabled. Affected file
2507 silcd/idlist.h, silcd/command[_reply].c.
2509 * SILC server adds now /var/run/silcd.pid everytime it is
2510 started. Affected file silcd/silcd.c.
2512 * Added silc_server_packet_send_clients to send a packet to
2513 the provided table of client entries. Affected file
2514 silcd/packet_send.[ch].
2516 * Fixed a crash in client resolving in client_prvmsg.c in
2517 client library. Affected file lib/silcclient/client_prvmsg.c.
2519 * Do not actually remove the client directly from ID cache
2520 during SERVER_SIGNOFF, but invalidate it. This way we
2521 preserve the WHOWAS info for the client. Affected file
2522 silcd/server_util.c.
2524 * Fixed SERVER_SIGNOFF notify handling in the server. The
2525 server is now able to process incoming SERVER_SIGNOFF notify
2526 for a server that it doesn't even know about. It will remove
2527 the clients provided in the notify. Affected file
2528 silcd/packet_receive.c.
2530 * Check for partial packet in data queue after every packet that
2531 was found from the queue. Return and wait for more data if
2532 there is partial data in queue. Affected file is
2533 lib/silccore/silcpacket.c.
2535 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * Added SilcClietFileError enum to indicate error in
2538 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2539 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2540 Affected files lib/silcclient/silcapi.h and
2541 lib/silcclient/client_ftp.c.
2543 * Check that newsize in silc_buffer_realloc is larger than
2544 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2546 * Added better monitor of file transfers. It now monitors
2547 key agreement protocol during the file transfer too. Added
2548 error reporting too. Affected files
2549 irssi/src/silc/core/silc-servers.c,
2550 irssi/src/fe-common/silc/module-formats.[ch].
2552 * Wrote a help file for FILE command.
2554 * Added silc_rng_global_get_byte_fast to get not-so-secure
2555 random data as fast as possible. Random data is read from
2556 /dev/urandom if available and from the SILC RNG if not
2557 available. It is used in padding generation. Affected file
2558 lib/silccrypt/silcrng.[ch].
2560 * All packets in client library are now processed synchronously.
2561 Optimized packet processing a lot. Affected file
2562 lib/silcclient/client.c.
2564 * All server connection packets are processing synchronously
2565 now in server, to optimize packet processing. Affected file
2568 * Include files are installed now only in Toolkit distribution
2569 if make install is given. Affected files: all Makefile.am's.
2571 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2573 * Assure that silc_client_notify_by_server_resolve does not
2574 resolve the client information multiple times. If it cannot
2575 be found by the first it cannot be found at all. Affected
2576 file lib/silcclient/client_notify.c.
2578 * Fixed WHOWAS command reply calling. Affected file
2579 lib/silcclient/command_reply.c.
2581 * Removed all references to silc_idlist_get_client from the
2582 Irssi SILC client since that call is internal call used by
2583 the library. The Irssi SILC client will use now client
2584 retrieval functions found in silcapi.h.
2586 * Fixed a bug in resolving nickname info before sending
2587 private message. It used freed memory. Affected file
2588 irssi/src/silc/core/silc-servers.c.
2590 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2592 * Assure my_channels statistics cannot go negative in server.
2593 Affected files silcd/server.c, silcd/server_util.c.
2595 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2597 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2599 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Win32 Toolkit changes. Affected files
2602 win32/silc.dsw, win32/libsilc/libsilc.def,
2603 win32/libsilcclient/libsilc.def,
2604 lib/silcutil/silcutil.c, and
2605 lib/sftp/sftp_fs_memory.c.
2607 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * Added silc_net_localip to return local host's IP address.
2610 Affected file lib/silcutil/silcnet.[ch].
2612 * If key exchange or rekey protocol is active for a connection
2613 parse all packets syncronously since there might be packets
2614 in packet queue that we are not able to process without first
2615 processing packets before them. Affected file silcd/server,
2616 lib/silcclient/client.c.
2618 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2619 whether library should continue processing the packet.
2620 Affected file lib/silccore/silcpacket.h.
2622 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2623 SilcSFTPMonitorData to SFTP server to monitor various
2624 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

2651 lib/silcutil/silcutil.[ch].
2653 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Resolve the client info when received private message or
2656 channel message for a client which nickname we don't know.
2657 Affected files lib/silcclient/client_prvmsg.c and
2658 lib/silcclient/client_channel.c.
2660 * Do not crash in /KEY if client is not connected. Affected
2661 file irssi/src/silc/core/silc-channels.c.
2663 * Added SilcClientStatus field to the SilcClientEntry in the
2664 lib/silcclient/idlist.h.
2666 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2667 is incomplete and is being resolved, it won't be resolved
2670 Make sure also that USERS command reply does not resolve
2671 twice information. Affected file is
2672 lib/silcclient/command_reply.c.
2674 Make sure that silc_client_get_clients_by_list does not
2675 resolve twice same information.
2677 * Check for valid client->id in the silc_server_free_client_data.
2678 Affected file silcd/server.c.
2680 * Fixed /GETKEY nick@server not to crash if the server entry
2681 is not found. Affected file lib/silcclient/command.c.
2683 * Fixed the silc_server_check_cmode_rights to check the
2684 requested modes correctly. Affected file silcd/command.c.
2686 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Better checks for non-printable chars in nick added.
2689 Affected file silcd/command.c.
2691 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Call the silc_server_udpate_servers_by_server in the
2694 primary router that comes back online in the backup resuming
2695 protocol. Otherwise it routes packets wrong. Affected file
2696 silcd/server_util.[ch], silcd/server_backup.c.
2698 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2701 lib/silcutil/silcbuffmt.[ch].
2703 * Redefined the SILC packet header to include the padding
2704 length. Affected file lib/silccore/silcpacket.[ch].
2706 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2707 length for maximum padding up to 128 bytes). Affected
2708 file lib/silccore/silcpacket.h.
2710 * Removed all backwards support for old 0.5.x MAC thingies.
2711 The SILC packet header change makes it impossible to be
2712 backwards compatible.
2714 * Send the ENDING packet with timeout in the backup resuming
2715 protocol. This is to assure that all routers has connected
2716 to the primary router. Affected file silcd/server_backup.c.
2718 * Changed the RNG to take the first IV from random data. It
2719 used to take it from zero actually. Changed the RNG also
2720 to use /dev/urandom during session. /dev/random is used
2721 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2723 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Changed the SILC packet header to have the first two bytes
2726 (the packet length) encrypted. Affected files aroung the
2727 code tree, lib/silccore/silcpacket.[ch]. Removed the
2728 SilcPacketCheckDecrypt callback. It is not needed anymore
2729 since the silc_packet_receive_process will determine now
2730 whether the packet is normal or special.
2732 * Implemented the unidirectional MAC keys. Affected files
2733 lib/silcske/silcske.c, silcd/protocol.c and
2734 lib/silcclient/protocol.c.
2736 * Implemented the packet sequence number to the MAC computation.
2737 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2738 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2739 lib/silcclient/protocol.c.
2741 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Allow backup router to announce servers. All servers
2744 announced by backup router are added to the global list
2745 automatically. Update hte server's socket to our primary
2746 router also when backup router announces a server.
2747 Affected file silcd/packet_receive.c.
2749 * Do not update the client->router in the function
2750 silc_server_udpate_clients_by_server if the client is on
2751 global list. We might fail to find any specific server
2752 for locally connected clients and local cell clients. They
2753 should still use the `from' and not `to' as client->router.
2754 This fixes backup router resuming protocol. Affected file
2755 silcd/server_util.c.
2757 * Decrease channel statistics count only if the channel
2758 deletion worked. Affected files are silcd/server.c and
2759 silcd/server_util.c.
2761 * Added silc_server_update_servers_by_server to update origin
2762 of all server entries. Used during backup router protocol.
2763 Affected files silcd/server_util.[ch], silcd/server.c. and
2764 silcd/backup_router.c.
2766 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2767 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2768 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2769 lib/silccrypt/silchmac.c.
2771 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Assure that router cannot reroute the same channel message
2774 to the sender. Affected file silcd/packet_receive.c.
2776 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Made better checks that the channel message is not sent
2779 to the router it came from. Affected file is
2780 silcd/packet_send.c. Fixed memory leak too.
2782 * Announce informations for incoming router connection, but
2783 only after checking if it is replaced by backup router.
2784 Affected file silcd/packet_receive.c.
2786 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2788 * Fixed the backup resuming protocol to work in multiple
2789 router environment. Affected file silcd/server_backup.c.
2791 * Route packet only to one router in the function
2792 silc_server_packet_send_to_channel. Affected file is
2793 silcd/packet_send.c.
2795 * Fixed silc_server_send_notify_dest to set the broadcast
2796 flag. Fixed the silc_server_send_notify_topic to actually
2797 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2798 Affected file silcd/packet_send.c.
2800 * Changed the SFTP Filesystem interface. Changed the
2801 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2802 the filesystem operation function. The SilcSFTPFilesystem
2803 is now a context that is allocated by all filesystem allocation
2804 functions and it already includes the operations structure
2805 and filesystem specific context. It is given as argument
2806 now to the silc_sftp_server_start. This made the interface
2807 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2808 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2810 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Changed the backup router adding and getting interfaces
2813 in the server. The router that will be replaced by the
2814 specified backup router is now sent as argument. Affected
2815 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2818 * Added silc_net_addr2bin_ne to return the binary form of
2819 the IP address in network byte order. Affected files
2820 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2822 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2824 * Check for existing server ID in silc_server_new_server
2825 and in silc_server_connect_to_router_final and remove the
2826 old entry if it exists. Affected file silcd/packet_receive.c,
2829 * Send the channel message always to only one router, either
2830 in upstream or downstream. Affected file is
2831 silcd/packet_send.c.
2833 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Wrote the definition of the backup resuming protocol to the
2836 protocol specification.
2838 * Removed one redundant channel key generation from normal
2839 server during joining procedure. Removed one redundant
2840 channel key sending from server to router during joining
2841 procedure. Affected file silcd/command.c.
2843 * Made minor bugfixes to the backup router resuming protocol.
2844 Affected file silcd/server_backup.c, server.c.
2846 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Added --disable-asm configuration option. Affected files
2849 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2852 * Implemented the backup resuming protocol that is used to
2853 resume the primary router position in the cell after the
2854 primary router comes back online. Affected files
2855 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2856 and silcd/server_util.[ch].
2858 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Sleep two (2) seconds after sending QUIT command to server.
2861 Affected file lib/silcclient/command.c.
2863 * Assure that if outgoing data buffer is pending do not force
2864 send any data. Affected file silcd/packet_send.c.
2866 * Assure that if outgoing data buffer is pending do not force
2867 send any data. Affected file lib/silcclient/client.c.
2869 * Implemented the backup router support when the primary router
2870 goes down. The servers and routers can now use the backup
2871 router as new primary router without loosing connectivity.
2873 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2876 in the server to indicate disabled entry. All data read
2877 from the connection will be ignored and no data is sent
2878 for entry that is disabled. Affected files are
2879 silcd/idlist.h, silcd/server.c.
2881 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Created SFTP client and server test programs in the
2884 lib/silcsftp/tests directory.
2886 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2888 * Implemented memory filesystem (virtual filesystem) for
2889 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2892 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * Implemented the SFTP (SSH File Transfer Protocol) to the
2895 lib/silcsftp. It includes SFTP client and SFTP server
2898 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Moved lib/silccore/silcprotocol.[ch] to the
2901 lib/silcutil library.
2903 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2904 take variable argument list pointer as argument. Affected
2905 file lib/silcutil/silcbuffmt.[ch].
2907 * Added silc_buffer_set function that is used to set data
2908 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2909 Affected file lib/silcutil/silcbuffer.h.
2911 * Changed various routines in the core library to use the new
2912 silc_buffer_set instead of allocating new buffer only for
2915 * Added 64-bit value formatting and unformatting support to the
2916 silc_buffer_[un]format routines. Affected file is
2917 lib/silcutil/silcbuffmt.[ch].
2919 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2920 to includes/bitmove.h.
2922 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2924 * Fixed channel user mode saving in client library. Affected
2925 file lib/silcclient/command[_reply].c.
2927 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Defined the file transfer to the SILC Protocol. Added
2930 new packet type SILC_PACKET_FTP and defined File Transfer
2931 Payload. The mandatory file transfer protocol is SFTP
2932 (SSH File Transfer Protocol). Affected file in addition
2933 of the internet draft is lib/silccore/silcpacket.h.
2935 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2936 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2937 is used as part of backup router protocol when the primary
2938 router of the cell is back online and wishes to resume
2939 the position as primary router.
2941 * Redefined the MAC generation keys in the protocol. The
2942 same key is not used anymore in both direction. Both
2943 direction will now use different keys for sending and
2944 receiving. This fixes a potential security flaw. This
2945 change causes incompatibilities in the protocol.
2947 * Redefined also the MAC computation from the packet.
2948 An packet sequence number is now added to the MAC
2949 computation. This prevents possible replay attacks against
2950 the protocol. This change too causes incompatibilities
2953 Added `sequence' field to the SilcPacketContext to hold
2954 the current sequence number for the packet.
2956 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Added `created' field to the SilcIDListData in the file
2959 silcd/idlist.h to indicate the time when the entry was
2962 * Added `created' field to the SilcChannelEntry too. Affected
2963 file silcd/idlist.h.
2965 * Added `creation_time' aguments to all the announcement functions
2966 in the server. If it is provided then only the entries that
2967 was created after the provided time frame are actually
2968 announced. Affected file silcd/server.[ch].
2970 * The protocol says that the Channel ID's IP address must be
2971 based on the router's IP address. Added check for this in
2972 the silc_server_new_channel when processing incoming New Channel
2973 Payload. Affected file silcd/packet_receive.c.
2975 * Print out the correct version with --version in SILC client.
2976 Affected file irssi/src/silc/core/silc-core.c.
2978 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Fixed WHOWAS command to check for completnes of the client
2981 entry always, not just when the command is coming from client.
2982 Affected file silcd/command.c.
2984 * Added new function silc_server_packet_queue_purge to purge the
2985 outgoing data queue to the network. After the function returns
2986 it is guaranteed that the outgoing packet queue is empty.
2987 Affected file silcd/packet_send.[ch].
2989 * Purge the outgoing packet queue in the rekey protocol's final
2990 callback to assure that all rekey packets go to the network
2991 before quitting the protocol. Affected file silcd/server.c.
2993 * Added silc_client_packet_queue_parse as similar function as
2994 in server to the client library. The affected file is
2995 lib/silcclient/client.c.
2997 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Splitted silcd/server.c and created silcd/server_util.[ch]
3000 for utility functions.
3002 * Added new socket flag SILC_SF_DISABLED to indicate that the
3003 connection is open but nothing can be sent to or received from
3004 the connection. Affected file lib/silcutil/silsockconn.[ch].
3005 The checking for disabled socket is checked in the low level
3006 silc_socket_write and silc_socket_read functions.
3008 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Allow only nicknames and channel names that fits into the
3011 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3013 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * When processing JOIN command reply in server check that if
3016 the channel exists in our global list we'll move it the local
3017 list. Affected file silcd/command_reply.c.
3019 * Fixed the check whether client is joined on the channel already
3020 in JOIN command. Affected file lib/silcclient/command.c.
3022 * Fixed the JOIN command reply to check whether the channel
3023 already exists. Affected file lib/silcclient/command_reply.c.
3025 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Added silc_ske_status_string to map the SKE error numbers
3028 to readable strings. The affected files are
3029 lib/silcske/silcske[_status].[ch].
3031 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Do not show the private channels on the WHOIS channel list
3034 as it is not allowed by the protocol. The affected file is
3037 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Assure that the packet length digged from the actual packet
3040 is something sensible in the silc_packet_decrypt_rest_special
3041 in lib/silccrypt/silcpacket.c.
3043 * Free and NULL the allocated pointer in silc_hmac_alloc if
3044 the HMAC allocation fails. The affected file is
3045 lib/silccrypt/silchmac.c.
3047 * Print the selected security properties to the log files in
3048 the server. Affected file silcd/protocol.c.
3050 * Add SKE's reference counter even if calling the completion
3051 callback manually. Otherwise it goes negative, although it
3052 does not cause any problems. The affected file is
3053 lib/silcske/silcske.c.
3055 * Remove the client entry with short timeout after giving the
3056 KILL command. Affected file lib/silcclient/command.c.
3058 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3059 case all found clients are already disconnected (WHOWAS would
3060 found them) in the server. Affected file silcd/command.c.
3062 * Update the last_receive (time of last data received) to be
3063 updated only when received private or channel message so that
3064 the idle time showed in WHOIS makes more sense.
3066 * Added boolean field `valid' in to the SilcClientEntry in the
3067 client library to indicate whether the entry is valid or not.
3068 This fixes the nickname change bug on channel when changing
3069 the nickname to be same than the old (like nick to Nick) the
3070 nickname formatter doesn't set the new nick anymore to Nick@host.
3071 Affected file lib/silcclient/idlist.[ch].
3073 * Now actually fixed the nickname changing on disconnection.
3074 Added new function silc_change_nick to the Irssi SILC Client.
3075 Affected file irssi/src/silc/core/client_ops.c,
3076 irssi/src/silc/core/silc-nicklist.[ch].
3078 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Check that the public key exists in the GETKEY command before
3081 trying to encode it. Affected file silcd/command.c.
3083 * Print some notifications on received public keys with GETKEY
3084 command in the Irssi SILC Client. Affected files are
3085 irssi/src/fe-common/silc/module-formats.[ch],
3086 irssi/src/silc/core/client_ops.c.
3088 * Use IDENTIFY command to resolve the server information in the
3089 GETKEY command instead of INFO command. Affected file
3090 lib/silcclient/command.c.
3092 * All command reply functions in the client library now calls
3093 the pending command reply callbacks even if an error has
3094 occurred. The server has done this a long time and now it was
3095 time to move the client library to this as well. Now all
3096 errors can be delivered back to the pending command reply
3097 callbacks if necessary. Affected files are
3098 lib/silcclient/command[_reply].[ch].
3100 * Change the nickname on disconnection back to the username
3101 because in reconnect the server will enforce it to it anyway.
3102 Affected file irssi/src/silc/core/silc-servers.c.
3104 * Fixed a config file parsing bug in the Irssi SILC client.
3105 Affected file irssi/src/silc/core/clientconfig.c.
3107 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * When printing the channel mode on JOIN, verify that the
3110 channel key and channel's HMAC are valid. Affected file
3111 irssi/src/silc/core/client_ops.c.
3113 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3116 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3117 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3119 * Removed channel key rekey task deleting from the function
3120 silc_server_save_channel_key. Affected file silcd/server.c.
3121 Added explicit timeout task context instead that is used to
3122 delete the task if we are registering a new task before the
3123 new task has elapsed.
3125 * When channel key rekey occurs the client library now saves
3126 the old channel key for a short period of time (10 seconds) and
3127 is able to use it in case some is still sending channel
3128 messages encrypted with the old key after the rekey. Affected
3129 file lib/silcclient/[idlist.h|client_channel.c].
3131 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Added check to the silc_server_new_id_real to not accept
3134 new ID if it is the sender's own ID. Affected file is
3135 silcd/packet_receive.c.
3137 * Assure that we do not announce ourself or the one we've
3138 sending our announcements when we're router and are announcing
3139 servers to our primary router. Affected file silcd/server.c.
3141 * Fixed silc_server_command_identify_check_client to assemble
3142 correct WHOIS packet. It send corrupted WHOIS packet and
3143 caused problem with router to router connections. Affected
3144 file silcd/command.c.
3146 Fixed also silc_server_command_whois_check the same way
3147 as for the IDENTIFY command.
3149 * Added new SilcIDListStatus to the server in the SilcIDListData
3150 structure. The status now includes the current status of
3151 the entry (like registered, resolved etc.). Affected file
3152 silcd/idlist.[ch]. Defined a bunch of different status types
3153 as well. This replaced the old boolean registered field as well.
3155 Added resolve_cmd_ident field to the SilcClientEntry structure
3156 too so that if the entry is for example being resolved so
3157 another command may attach to the same pending command reply
3158 without requiring to resolve the same entry again. This concept
3159 should optimize the WHOIS and the IDENTIFY resolving under
3160 heavy load by taking away unnecessary resolving for entries
3161 that are being resolved already.
3163 Added support for adding multiple pending commands for one
3164 command idenfier. Affected file silcd/command[_reply].[ch].
3166 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3167 before deleting the data. Otherwise the hash table will have
3168 freed data in comparison functions. Affected file is
3169 silcd/command_reply.c.
3171 * Fixed silc_idlist_replace_client_id to add the new entry to
3172 the cache with NULL nickname. Otherwise there will be invalid
3173 memory as the nickname after the nickname is freed. Affected
3174 file silcd/packet_receive.c.
3176 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3177 saved into wrong slots because the previous number of entries
3178 was not taken into account. Affected file silcd/idlist.c.
3179 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3181 * If we are router and we receive JOIN notify to a channel that
3182 does not have any users then notified client is marked as the
3183 channel founder, as it is it. The affected file is
3184 silcd/packet_receive.c
3186 * Added to the extended hash table API's table_del_*ext functions
3187 the destructor as argument too, so that the caller can decide
3188 which destructor to use or whether to use destructor at all.
3189 Affected file lib/silcutil/silchashtable.[ch].
3191 * Fixed ID Cache purging. It actually deleted the entries from
3192 the hash table after the data was freed. The hash table ended
3193 up comparing freed memory. The affected file is
3194 lib/silccore/silcidcache.c.
3196 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3198 * Fixed Irssi SILC client's KILL command's HELP syntax.
3200 * The USERS command now resolves the detailed user information
3201 if the userinfo field is missing. Affected file is
3202 lib/silcclient/command_reply.c.
3204 * Do not print error in silc_file_read if the read file does
3205 not exist. Just silently return NULL. Affected file is
3206 lib/silcutil/silcutil.c.
3208 * Fixed the silc_log_output to not wine about NULL filename
3209 and to not create some bogus " " filename. Affected file is
3210 lib/silcutil/silclog.c.
3212 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Fixed various printing bugs on the user interface in the
3215 Irssi SILC Client. Minor changes that were forgotten from
3218 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Fixed the configure.in.pre and the compilation and distribution
3221 environment to support the new autoconf 2.52. That version is
3222 now required to compile the CVS trunk.
3224 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3227 to generally parse user@fqdn format strings. Affected file
3228 lib/silcutil/silcutil.c.
3230 * Added nickname_format and nickname_force_format fields to the
3231 SilcClientParams structure. The first one defines the format
3232 for the nicknames that the library will enforce if the receives
3233 multiple same nicknames. The second one is boolean value and
3234 can be used to force the library to always enforce the format
3235 to the nicknames regardles whether there are multiple nicknames
3236 or not. This configurable formatting was employed to flexibly
3237 support accessing multiple nicknames from the user interface.
3238 The userinterface can now set the nicknames to what ever format
3239 they prefer. Affected file lib/silcclient/silcapi.h.
3241 Added function silc_client_nickname_format to the file
3242 lib/silcclient/idlist.c. It performs the nickname formatting.
3244 Added new field `hostname´ to the SilcClientEntry context.
3245 It holds the hostname of the client. Affected file is
3246 lib/silcclient/idlist.h.
3248 * Irssi SILC Client sets the nicknames in nick@hostn format.
3249 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3250 irssi/src/silc/core/silc-core.c.
3252 The WHOIS printing now also shows both the real nickname and
3253 the formatted nickname so that user knows how to access the
3254 user if there are multiple same nicknames cached. Affected
3255 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3256 printing formatting too to take the hostname now as a separate
3257 argument. The Affected file is
3258 irssi/src/fe-common/silc/modules-formats.[ch].
3260 * Changed the silc_client_get_clients_local to accept the formatted
3261 nickname as argument. It accepts the real nickname too but the
3262 formatted nickname can be used to find the true entry from
3263 multiple entries. Affected file lib/silcclient/silcapi.h and
3264 lib/silcclient/idlist.c.
3266 * Added nickname_format_parse field to the SilcClientParams.
3267 It is a callback function provided by the application to parse
3268 the nickname out of the formatted nickname string. The library
3269 calls it to get the nickname from the formatted string. Since
3270 the application generally knows better the format of the nickname
3271 string it parses it instead of the library, even though library
3272 encodes the formatted string. If the callback function is not
3273 provided then the library will use the string as is. The
3274 affected file is lib/silcclient/silcapi.h.
3276 * All the nickname strings passed to the client library in
3277 commands are now expected to be formatted nickname strings.
3278 If the command does not support the formatted nickname string
3279 it will assume that the sent string is the actual nickname.
3280 Affected file lib/silcclient/command.c.
3282 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * Added public key authentication support to OPER and SILCOPER
3285 commands in the client library. Affected file is
3286 lib/silcclient/command.c.
3288 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Changed the get_auth_methdod client operation to be asynchronous.
3291 It can be async if the application resolves the authentication
3292 method from the server during the negotiation. Added new
3293 SilcGetAuthMeth completion callback that the application will
3294 call after resolving the authentication method.
3296 Added function silc_client_request_authentication_method that
3297 the application can use to resolve the authentication method
3298 from the server. Added also SilcConnectionAuthRequest callback
3299 that the library will call after the server has replied. The
3300 application can call this function if it does not know the
3301 current authentication method.
3303 Affected files are lib/silcclient/client.c and
3304 lib/silcclient/silcapi.h.
3306 * The Irssi SILC client now automatically resolves the authentication
3307 method incase any configuration information is not present (and
3308 currently there never is). The affected file is
3309 irssi/src/silc/core/client_ops.c.
3311 * Fixed public key authentication from the client library.
3312 Affected file lib/silcclient/protocol.c. Changed also the
3313 protocol specification about the public key authentication in
3314 the connection authentication protocol. The actual data to be
3315 signed is now computed with a hash function before signing.
3317 * Fixed the public key authentication from the server as well.
3318 Affected file silcd/protocol.c.
3320 * Removed the mlock()'s from the memory allocation routines.
3321 Affected file lib/silcutil/silcmemory.c. The ./configure does
3322 not check anymore for the mlock(). Affected file is
3325 * Fixed USERS command in server to allow the execution of the
3326 command for private and secret channels if the client sending
3327 the command is on the channel. Affected file silcd/command.c.
3329 * Fixed silc_client_get_clients_local to return the clients
3330 count correctly. It could return wrong value. Affected file
3331 lib/silcclient/idlist.c.
3333 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3335 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3336 types. The assembler optimizations seemed not to like 64-bit
3337 data types. The assmebler optimizations thus are now enabled
3338 also for BSD systems as opposed to only enable them for Linux.
3340 * Do not check for threads at all on BSD systems. Affected
3341 file configure.in.pre.
3343 * Removed -n and -h options from the Irssi SILC Client since
3344 they are not used in silc.
3346 * Fixed the prime generation to assure that the first digit
3347 of the generated random number is not zero since our conversion
3348 routines does not like number strings that starts with zero
3349 digit. If zero digit is seen the random number is regenerated.
3350 This caused some corrupted RSA keys when the zero first digit
3351 was met. Affected file lib/silcmath/silcprimegen.c.
3353 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Fixed WIN32 configuration in the ./configure script.
3356 Fixed to include xti.h on environments that has it.
3357 Patches by Carsten Ilchmann and andrew.
3359 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Changed the silc_id_create_client_id to be collision
3362 resistant. It is now assured that there cannot be created
3363 two same client ID's. I suspect that some weird bugs in
3364 the server were actually caused by duplicate Client IDs.
3365 Affected file silcd/serverid.[ch]. A router receiving
3366 new ID now also assures and informs the sending server
3367 if the ID caused collision.
3369 * Changed the silc_id_create_channel_id to also assure that
3370 there are no collisions.
3372 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Statement about ignoring the Mutual Authentication flag when
3375 performing rekey with PFS was a bit misleading. It is ignored
3376 if it was set in the initial negotiation, it cannot be even
3377 set in the rekey. Fixed in the ke-auth draft. Started the
3378 new versions of the protocol drafts in the doc/.
3380 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Fixed a bug in silc_client_command_identify_save when saving
3383 new channel information. The channel name was no duplicated
3384 and caused crash on exit. Affected file is
3385 lib/silcclient/command_reply.c.
3387 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Fixed the getkey command handling in the server. Send just
3390 empty OK reply to the sender if the key could not be fetched
3391 (but everything else was ok, like the key just was not available).
3392 Changed the public key parameter to optional in the protocol
3393 specs so that empty OK reply can be sent. Affected file
3396 Added a message to Irssi SILC client to tell to user if the
3397 server did not return a public key.
3399 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * Fixed a channel key regeneration bug. It registered new
3402 timeout tasks exponentially until all system resources were
3403 used. Affected file silcd/server.c.
3405 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * Added the SILC Document generator to the scripts/silcdoc.
3408 It can be used to generate the Toolkit Reference Manual out
3409 of the source tree. Internally it will also use the RoboDoc
3410 generator now imported in util/robodoc.
3412 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Added couple of return's in rekey protocol if error orccurred
3415 during the protocol. The execution must be terminated.
3416 Affected file silcd/protocol.c. Also, terminate the protocol
3417 always with timeout.
3419 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * The client's Client ID was created initally from the wrong
3422 nickname (it could have been in format nick@host) in the
3423 silc_server_new_client. Affected file silcd/packet_receive.c
3425 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * Added some SILC_LOG_ERROR's to various error conditions
3428 if client could not be added to ID cache. Affected files
3429 silcd/packet_receive.c and silcd/server.c.
3431 * When client's sock->user_data is freed, NULL also the
3432 client->router and client->connection pointers. Added check
3433 for these pointers being NULL to various places around the
3434 code. Affected file silcd/server.c.
3436 * Added client->data.registered == TRUE checks to various
3437 places around the code to assure that unregistered client's
3438 are not handled when it is not allowed. Affected file
3441 * Added `bool registered' fields to all
3442 silc_idlist_[server|client]_get_* routines to indicate whether
3443 the fetched client needs to be registered or not. Affected
3444 file silcd/idlist.[ch].
3446 * Add your own entry as registered to the ID cache in the
3447 server. Affected file server.c.
3449 * Fixed a bug in silc_server_new_server. The SilcServer was
3450 set as the new server's context instead of SilcServerEntry.
3451 This naturally caused some weird bugs.
3453 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Do not delete the channel rekey task when adding it
3456 for in silc_server_create_channel_key.
3458 * Changed the silc_server_create_channel_key to return
3459 TRUE or FALSE to indicate the success of the channel key
3462 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Fixed MSVC++ project files and added missing files to
3465 Makefiles under win32/.
3467 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Do not add TCP_NODELAY flag if the operating system
3470 does not have it defined. Affected files are
3471 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3473 * Fixed buffer overflow from Irssi SILC Client. Affected
3474 file irssi/src/fe-common/core/themes.c.
3476 * Fixed double free in client library in the file
3477 lib/silcclient/client.c when disconnecting from server.
3479 * Applied double free patch from cras to Irssi SILC client.
3480 Affected files irssi/src/core/[modules/expandos].c
3482 * Fixed the disconnection handling to Irssi SILC Client.
3483 The application must call silc_client_close_connection
3484 in ops->connect client operation in case of failure of
3485 the connection. Affected file is
3486 irssi/src/silc/core/client_ops.c.
3488 * Do not set sock->protocol to NULL in the function
3489 silc_client_close_connection after executing the protocol's
3490 final callback since the sock might not be valid anymore.
3491 Affected file lib/silcclient/client.c.
3493 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3495 * Do not enable SILC_THREADS if the linking with libpthread
3496 did not happen. Affected file configure.in.pre.
3498 * Added notion to protocol specification that server must
3499 verify the sent authentication payload with CMODE when
3500 setting the channel founder key. Implemented it to the
3501 server. Affected file silcd/command.c.
3503 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Added _EXTRA_DIST SILC distribution variable to the
3506 distributions file. It is used to conditionally add extra
3507 files or directories to the specific distribution. Affected
3508 files ./prepare, Makefile.am.pre and distributions.
3510 Removed the `_' from the start of the distribution names.
3513 * Added README.WIN32 for instructions to compile the Toolkit
3516 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Fixed a double free in disconnection in the server. Affected
3519 file is silcd/server.c.
3521 * Fixed the lib/silcske/groups.c to work now also with GMP
3522 MP library. The string conversion did not work when using
3523 specific base and the base is indicated in the string as well.
3525 * Created win32/ directory which now includes MSVC++ specific
3526 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3527 It will appear only in the toolkit distribution
3529 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3531 * Changed the key material distribution function in case when
3532 the hash output is too short. The data is now concatenated
3533 a bit differently than it used to. Made the change to the
3534 SKE protocol specification.
3536 * Added better GMP detection to configure.in.pre. A patch
3539 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Fixed a minor bug in SKE that might cause some problem on
3542 some platforms. Affected file lib/silcske/silcske.c.
3544 * Added the cookie checking for initiator in the SKE. It checks
3545 that the responder returns the sent cookie unmodified. The
3546 affected file is lib/silcske/silcske.c. Added new SKE
3547 error type INVALID_COOKIE that can be sent during the
3548 negotiation. Fixed some memory leaks as well.
3550 * Added the "invalid cookie" error message to Irssi SILC client's
3553 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Added `task_max' field to the SilcClientParams to indicate
3556 the maximum tasks the scheduler can handle. If set to zero,
3557 default values are used. Affected file lib/silcclient/silcapi.h.
3559 * Fixed memory leaks in silc_client_close_connection. Affected
3560 file lib/silcclient/client.c.
3562 * Added silc_client_del_client_entry to client library to free
3563 all memory of given client entry. Affected file is
3564 lib/silcclient/idlist.[ch].
3566 * Added new functions silc_client_del_channel and
3567 silc_client_del_server to delete channel and server entries.
3568 Affected file lib/silcclient/[silcapi.h/idlist.c].
3570 * Removed silc_client_del_client_by_id from silcapi.h.
3572 * Fixed the INFO command to return the server's own info
3573 correctly when querying by Server ID. Affected file is
3576 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Removed the non-blocking settings in WIN32 code in the
3579 silc_sock_[read/write] and added SleepEx instead. Affected
3580 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3581 of input data is now checked with FIONREAD and ioctlsocket.
3583 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3585 * Call silc_schedule_task_del_by_context in the
3586 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3587 Affected file lib/silccore/silcprotocol.c.
3589 * Call silc_protocol_cancel for active protocols in the
3590 silc_server_close_connection if the funtion
3591 silc_server_free_sock_user_data has not been called.
3592 Affected file silcd/server.c.
3594 * Generic tasks cannot be deleted using the del_by_fd
3595 task deleting function since generic tasks does not match
3596 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3598 * Added a notion to SILCOPER help file that the SILCOPER works
3599 only on router server, not on normal server.
3601 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Added for WIN32 support for the new scheduler as well.
3604 Affected file lib/silcutil/win32/silcwin32schedule.c.
3606 * Fixed the SHA1 implementation to work on various platforms.
3608 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3610 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3611 API. It is part of the scheduler now. Everything else is
3612 as previously but some functions has changed their names.
3613 Checkout the lib/silcutil/silcschedule.h for the interface.
3614 Updated all applications to use the new interface. Affected
3615 files are lib/silcutil/silcschedule.[ch].
3617 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3619 * Found a bug in the SKE implementation. The HASH value,
3620 specified by the protocol, was not computed correctly. The
3621 public key of the responder was not added to the computation
3622 even though it is mandatory. Affected file lib/silcske/silcske.c.
3623 This unfortunately causes incompatibilities with older
3624 clients and servers.
3626 * Added WIN32 specific network init and uninit functions:
3627 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3628 the Winsock2. Affected file lib/silcutil/silcnet.h and
3629 lib/silcutil/win32/silcwin32net.c.
3631 * Set the socket always to nonblocking mode on WIN32 after
3632 reading data or writing data. Affected file is
3633 lib/silcutil/win32/silcwin32sockconn.c.
3635 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3637 * Fixed various compilation problems under WIN32. Affected
3638 files lib/silcutil/win32/silcwin32thread.c and
3639 lib/silcutil/win32/silcwin32schedule.c.
3641 * Removed all _internal.h #includes from public header
3642 files. Internal headers must never be included from
3645 Removed also the lib/silcske/payload_internal.h file.
3647 * All include files that may be needed (public and some others
3648 included by the public headers) by application developers are
3649 now copied to the ./includes directory. It does not copy any
3650 internal headers. Affected file Makefile.defines.pre and all
3651 Makefile.am's under lib/ and subdirs.
3653 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3655 * Do not change the ~/.silc directory's permissions automatically.
3656 Affected file irssi/src/silc/core/clientutil.c.
3658 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3660 * Do not cancel the protocol in silc_server_close_connection
3661 it might cause recursion. Now cancelled in the function
3662 silc_server_free_sock_user_data. Affected file silcd/server.c.
3664 * Fixed the silc_server_remove_clients_by_server to regenerate
3665 the channel keys correctly finally. Added also new function
3666 silc_server_remove_clients_channels to actually do it.
3667 Affected file silcd/server.c.
3669 * Fixed the silc_server_new_channel to not crash by giving
3670 wrong router to the new channel. Affected file is
3671 silcd/packet_receive.c.
3673 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3676 which is given as argument to the silc_client_alloc now.
3677 It can be used to configure the client and set various parameters
3678 that affect the function of the client.
3680 * The USERS command in server did not check whether the channel
3681 is private or secret. Affected file silcd/command.c.
3683 * Added new argument to the USERS command in protocol specification.
3684 The USERS command now can take the channel name as argument
3685 as well. Added support for this in client and server and
3686 updated the protocol specs.
3688 * Completed the GETKEY command in client. It can be now used
3689 to fetch also servers public key not only some clients.
3690 Affected files lib/silcclient/command[_reply].c.
3692 * Added silc_client_get_server to return server entry by the
3693 server name. Affected files lib/silcclient/silcapi.h and
3696 * Redefined the IDENTIFY command in protocol specification to be
3697 more generic. It now can be used to query information about
3698 any entity in the SILC Network, including clients, servers and
3699 channels. The query may be based either the entity's name
3700 or the ID. Added support for this in both client and server.
3702 Affected files silcd/command.c and lib/silcclient/command.c
3703 and command_reply.c.
3705 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3706 the _from_client and _from_server functions. Affected file
3709 * Added silc_client_get_channel_by_id_resolve to the file
3710 lib/silcclient/silcapi.h to resolve channel information by
3711 its ID. Added also silc_client_get_channel_by_id that
3712 does not resolve it from the server.
3714 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3716 * Added SilcServerEntry context into the client library
3717 to represent one server. The INFO command now allocates
3718 these to save the resolved server info. For now on the
3719 client library will also keep information about servers,
3720 connected and resolved with INFO.
3722 The INFO command now allocates the SilcServerEntry context
3723 and saves the server info there. The COMMAND_REPLY in
3724 the INFO now returns the parameters to application in
3725 same order as defined in the protocol specification.
3727 The entries are cached in the client->server_cache.
3729 * The INFO command is now issued after received the Client ID
3730 from the server. Affected file lib/silcclient/client.c.
3732 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3733 to the application as the mode changer might be server.
3734 It is guaranteed that NULL is not returned anymore to the
3735 application. Affected file lib/silcclient/client_notify.c.
3737 The ID Type is now also passed to the application so that
3738 it can check whether the returned entry is SilcClientEntry
3741 Added new function silc_client_get_server_by_id to return
3742 the server entry by ID. Affected files are the
3743 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3745 * Do not create the channel in the Irssi SILC Client when issuing
3746 the JOIN command but when received the sucessful JOIN command
3747 reply. Otherwise the channel might get created even though we
3748 could not join it. The Affected file is
3749 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3751 * Fixed a channel joining bug in router. The router must also
3752 check the channel modes, invite and ban lists etc. when serving
3753 the JOIN command sent by normal server. Affected file is
3754 silcd/command.c. The router now resolves the client's
3755 information from the server who sent the JOIN command if it
3756 does not know it, and processes the JOIN command only after
3759 * Changed the SilcCommandCb to take new argument; void *context2.
3760 Affected file lib/silccore/silccommand.h
3762 The second argument in the command callbacks in the server now
3763 includes the SilcServerCommandReplyContext if the command was
3764 called as pending command callback from the command reply.
3765 Otherwise it is NULL. When called as pending the status of the
3766 command reply will be checked and if it was erronous the
3767 error will be sent to the original sender of the command.
3768 This way the client always receives the error messages even
3769 though the server was actually the one who received the error
3770 when it resent the command to router, for example. Affected
3771 files silcd/command[_reply].[ch].
3773 * Fixed sending WHOWAS command's error message to client if
3774 the requested client could not be found. It was missing.
3777 * Changed the CMODE and CUMODE commands reply arguments in the
3778 protocol specification. The Channel ID is now sent in both
3779 of the commands to identify the channel. Implemented this
3780 new feature to the client and server. Affected files
3781 lib/silcclient/command_reply.c and silcd/command.c.
3783 * Made better checks for invite and ban lists in the JOIN
3784 command in server. Affected file silcd/command.c.
3786 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3788 * The server now performs the incoming host IP/DNS lookup
3789 using the silc_socket_host_lookup and thus does not block
3790 the server anymore. Affected file silcd/server.c.
3792 * Completed the multi-thread support for SILC Scheduler in
3793 the lib/silcutil/silcschedule.c.
3795 * Fixed the configure.in.pre to detect the pthread correctly
3798 * Fixed a deadlock in silc_task_queue_wakeup in the file
3799 lib/silcutil/silctask.c.
3801 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3803 * Added new function silc_schedule_wakeup that is used in
3804 multi-threaded environment to wakeup the main thread's
3805 schduler. It needs to be used when a thread adds a new task
3806 or removes a task from task queues. After waking up, the
3807 scheduler will detect the task queue changes. If threads
3808 support is not compiled in this function has no effect.
3809 Implemented the wakeup mechanism to both Unix and WIN32
3810 systems. Affected files are lib/silcutil/silcschedule.[ch],
3811 lib/silcutil/unix/silcunixschedule.c and the
3812 lib/silcutil/win32/silcwin32schedule.c.
3814 * Added new function silc_task_queue_wakeup to wakeup the
3815 scheduler by the specified task queue. Affected file
3816 lib/silcutil/silctask.[ch].
3818 * The silc_socket_host_lookup_start now wakes up the scheduler
3819 after adding the timeout task. Affected file is
3820 lib/silcutil/silcsockconn.c.
3822 * The silc_socket_host_lookup is synchronous now if the threads
3823 support is not compiled in. However, the callback is still
3824 called asyncronously through the scheduler, anyway. Affected
3825 file lib/silcutil/silcsockconn.c.
3827 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3829 * Added new function silc_socket_host_lookup to perform
3830 asynchronous IP and FQDN lookups for the socket connection.
3831 Affected files lib/silcutil/silcsockconn.[ch].
3833 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3835 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3836 that may or may not compile the mutex support in.
3838 Changed the silc_mutex_alloc interface. It allocates the
3839 mutex now to the sent pointer and returns TRUE or FALSE.
3841 Affected file lib/silcutil/silcmutex.h.
3843 * Wrote the SILC Task Queue interface to support multi-threads.
3844 Affected file lib/silcutil/silctask.[ch].
3846 * Wrote the SILC Scheduler to support multi-threads. Affected
3847 file lib/silcutil/silcschedule.c.
3849 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3851 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3852 in lib/silcutil/win32/.
3854 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3856 * Defined SILC Mutex API and SILC Thread API and implemented
3857 them for Unix. Affected files are
3858 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3859 lib/silcutil/unix/silcunixmutex.c and
3860 lib/silcutil/unix/silcunixthread.c.
3862 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * Fixed the silc_server_remove_clients_by_server's channel
3865 key re-generation. The hash table handling was incorrect
3866 and would not work with many channels. Affected file is
3869 * Fixed some memory leaks around the server code.
3871 * Rewrote the silc_server_get_users_on_channel to support IPv6
3872 based Client ID's. Affected file silcd/server.c.
3874 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3875 specification. However, a separate document must be written
3876 to define the detailed signing procedure and the payload
3877 associated with the flag. Defined the flag to the
3878 lib/silccore/silcchannel.h as well.
3880 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3882 * Changed the dynamic tables to static size tables in the
3883 lib/silccrypt/silchmac.c.
3885 * Removed GCC dependencies from the code. A patch by cras.
3887 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3889 * Do not show the error "Error receiving packet bla bla"
3890 in server if it really was not an error (-2 means that reading
3891 is pending). Affected file silcd/server.c.
3893 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Fixed a possible crash in silc_server_remove_clients_by_server
3896 in silcd/server.c. Fixed there also some memory leaks.
3898 * Fixed the silc_idlist_replace_client_id. It could replace
3899 wrong key in the hash table. Affected file silcd/idlist.c.
3901 * Do not check whether there are global users on the channel
3902 if the channel->global_users is FALSE. Affected functions
3903 silc_server_remove_from_one_channel and
3904 silc_server_remove_from_channels in silcd/server.c. Also,
3905 do not check if the removed client is local as we can be
3906 sure that global client was not removed from the channel
3907 and checking for global users is not needed.
3909 * The silc_server_remove_clients_by_server now re-generates
3910 the channel keys correctly for those channels that had
3911 clients removed from them. Affected file silcd/server.c.
3913 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3915 * Found the reason of random crashes in the server. We weren't
3916 ignoring the SIGPIPE signal (which can be sent in write())
3917 and it crashed the server. Affected file silcd/silcd.c.
3919 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3921 * Assure that sock->user_data is not NULL in the function
3922 silc_server_packet_send in silcd/packet_send.c.
3924 * Disconnect the remote connection if it could not be added
3925 to any ID lists in the server. The affected file is
3928 * Check in silc_server_packet_send[_real/dest] that the
3929 socket is not disconnecting and ignore the data if it is.
3930 Affected file silcd/packet_send.c.
3932 * Define inline to __inline on native WIN32 compilation.
3933 Affected file includes/silcwin32.h.
3935 * Added some explicit type casts for inline code since MSVC
3936 require them. Affected files lib/silcutil/silcbuffer.h,
3937 lib/trq/silcdlist.h and lib/trq/silclist.h.
3939 * Print warning in log files from now on if the packet
3940 decryption fails. Affected file silcd/server.c.
3942 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3944 * Changed the `say' client operation's interface to accept
3945 new `type' argument to indicate the type of the message sent
3946 by the library. The application may filter the library's
3947 messages according the type. The affected file is the
3948 lib/silcclient/silcapi.h.
3950 * Added two new functions to lib/silcclient/silcapi.h:
3951 silc_client_del_client and silc_client_del_client_by_id.
3952 Affected file lib/silcclient/idlist.c.
3954 * Moved the clientincludes.h from includes/ to silc/ and
3955 serverincludes.h from includes/ to silcd/.
3957 * The modes for the CMODE and CUMODE are now passed as
3958 uint32 for application with COMMAND_REPLY. The affected
3959 file is lib/silcclient/command_reply.c.
3961 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * /WHOIS without arguments shows client's own information.
3964 Affected file lib/silcclient/command.c.
3966 * Changed PING to not accept any arguments. The specs
3967 says that client can ping only the connected server so
3968 requiring an argument is not needed. Affected file is
3969 lib/silcclient/command.c.
3971 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Fixed a fatal bug in private message sending and reception
3974 encryption and decryption when using private message keys.
3975 The implementation was incorrect and did not follow the
3976 specification. It causd that some of the message were
3977 lost since it did not use the sending and receiving keys
3978 as the protocol suggests. This has been fixed and will cause
3979 incompatibilities with older clients when sending private
3980 message encrypted with private message keys. Affected files
3981 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3982 and various other in Irssi SILC Client.
3984 Added `responder' boolean argument to the functions
3985 silc_client_add_private_message_key[_ske] to indicate when
3986 the key is added as responder or initiator of the key
3989 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Removed the silc_ske_check_version function and created
3992 a SilcSKECheckVersion callback. Added also a function
3993 silc_ske_set_callbacks that is now used to set all SKE
3994 callbacks. The callback functions are not given to
3995 the SKE functions anymore, but this function is used to
3998 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4000 * Added `silc_version' argument to the silc_client_alloc
4001 to define the version of the application for the library.
4002 The library will use the version string to compare it
4003 against the remote host's (usually a server) version
4004 string. Affected file lib/silcclient/silcapi.h
4006 * Added the KE protocol context to Key Agreement context
4007 in client library so that we can abort the SKE if it
4008 is in process when we get timeout. Affected file is
4009 lib/silcclient/client_keyagr.c.
4011 * Do not resolve the client ID forever if it returns in the
4012 first time that such client does not exist. This was done
4013 for example with private message. Affected file is
4014 lib/silcclient/client_prvmsg.c.
4016 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4018 * Do not add regex.h for WIN32. The affected file
4019 includes/silcincludes.h.
4021 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4022 not work yet 100%. It generates the DLL's automatically
4023 when compiling with --with-win32 under cygwin.
4025 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4027 * lib/contrib/regex.c is not compiled on WIN32.
4029 * Added silc_net_get_socket_opt function to the
4030 lib/silcutil/silcnet.h.
4032 * Added includes/silcwin32.h for WIN32 specific includes
4035 * Do not use ptime structure or any of the posix process
4036 functions on WIN32 in lib/silccrypt/silrng.c.
4038 * Added silc_gettimeofday to provide generic function
4039 for struct timeval on all platforms. Added the function
4040 to lib/silcutil/silcutil.h.
4042 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4045 library as they clearly belong there. As a plus side we
4046 can make the actual socket connection routines platform
4049 Added also new generic function silc_socket_read and
4050 silc_socket_write (that used to be silc_packet_[read/write].
4051 The implementation of these are platform specific.
4053 * Added WIN32 specific routines of silc_socket_[read/write]
4054 to lib/silcutil/win32/silcwin32sockconn.c.
4056 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4058 * Added preliminary support for native WIN32 compilation under
4059 cygwin (using the -mno-cygwin option for GCC) to the
4060 ./configure.in.pre. The --with-win32 now prepares the
4061 compilation for native WIN32.
4063 * Rewrote the SILC Scheduler interface in the file
4064 lib/silcutil/silcschedule.h. The scheduler is now context
4065 based and does not have anymore any global static scheduler.
4066 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4067 and created lib/silcutil/win32 directory for WIN32 based
4070 * Added Unix specific network routines to the
4071 lib/silcutil/unix/silcunixnet.c and the old
4072 lib/silcutil/silcnet.c includes now only generic routines.
4074 Added WIN32 specific network routines to the
4075 lib/silcutil/win32/silcwin32net.c.
4077 * Added Unix specific utility functions from the
4078 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4080 * Added WIN32 SILC Scheduler to the file
4081 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4084 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4086 * Do not handle JOIN notify in the server if the target client
4087 is not registered (idata->registered == FALSE). The affected
4088 file is silcd/packet_receive.c.
4090 * Update the nickrec->founder in event_cumode in the Irssi SILC
4091 client. Affected file irssi/src/silc/core/silc-channels.c.
4093 * Fixed the CUMODE_CHANGE notify handling in the server when
4094 server and router are announcing their clients on channels.
4095 Now the mode changes are saved and notified correctly. The
4096 affected file is /silcd/packet_receive.c.
4098 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4099 They really did not replace the cache entry in the ID Cache.
4100 Now they do that. Affected file silcd/idlist.c.
4102 * Fixed the KICK notify handling in the Irssi SILC client to
4103 update the channel records so that the kicked client does not
4104 appear to be on the channel. The affected file is
4105 irssi/src/silc/core/silc-channels.c.
4107 * Always update the conn->current_channel when executing command
4108 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4110 * Fixed the KILL notify handling in Irssi SILC client to remove
4111 the killed client on all channels.
4113 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Fixed the silc_parse_command_line to remove extra spaces
4116 from the start and end of the arguments. Affected file is
4117 lib/silcutil/silcutil.c.
4119 * Cancel and free any active protocol in the function
4120 silc_server_close_connection. Affected file silcd/server.c.
4122 * Cancel and free any active protocol in the function
4123 silc_client_close_connction. Affected file is
4124 lib/silcclient/client.c.
4126 * Do not execute the KILL command for clients that are in
4127 history (ie. they are not in the network). Affected file is
4130 * Fixed KILL notify handling, client does not crash anymore.
4131 Affected file irssi/src/silc/core/silc-channels.c.
4133 * Reduced the default packet buffer size from 2048 to 1024 in
4134 lib/silccore/silcpacket.c.
4136 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4137 counter to the SKE context that is incresed when the SKE library
4138 performs async operation outside the library. If the outside
4139 process frees the SKE context and FREED status will be set
4140 and the library will detect after the sync operation that the
4141 libary is freed. The affected files are
4142 lib/silcske/silcske[_status].[ch].
4144 * Resolve the client entry information in the function
4145 silc_client_channel_message to assure that NULL pointer is not
4146 passed as client entry to the application. */
4148 * Fixed the task timeout calculation to assure that there is
4149 never negative timeouts. The affected file is
4150 lib/silcutil/silcschedule.c.
4152 * Fixed the channel user mode notification sending in server.
4153 It was sent point-to-point to the router (or to server by router)
4154 but it needs to be destined to a channel. The routines now
4155 supports sending the channel user mode notifys to the channels
4156 when announcing clients and channels. Affected files are
4157 silcd/server.c and silcd/packet_receive.c.
4159 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4160 It did not actually replace the old channel entry in the cache.
4161 Affected file lib/silcclient/client_notify.c.
4163 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Fixed a possible crash in silc_packet_send_prepare. It now
4166 assures always that there is enough space in the buffer and
4167 at the tail area of the buffer (for MAC).
4169 Fixed the inbound buffer reallocation in silc_packet_read.
4170 It was old code and did not handle the reallocation correctly.
4173 The affected file is lib/silccore/silcpacket.c.
4175 * Fixed buffer overflow in silc_parse_nickname in the file
4176 lib/silcutil/silcutil.c.
4178 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * make install generates new server keys only if there is not
4183 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4186 Added check that if the NOREPLY is set then we will not send
4187 the away message. This avoids infinite loop of away messages
4188 if both clients are away. The affected file is
4189 lib/silcclient/client_prvmsg.c.
4191 * Fixed client crash if /NICK was given without arguments.
4192 Affected file lib/silcclient/command.c.
4194 * Server does not send the invite list in INVITE command back
4195 to the client if the list was not altered. Added this notion
4196 to the protocol spec as well. Affected file silcd/command.c.
4198 Fixed possible crash in INVITE command by checking the
4199 value of silc_server_get_client_route command.
4201 * Fixed the INVITE notify type handling. The arguments are now
4202 taken in correct order and client does not crash. The affected
4203 file is irssi/src/silc/core/silc-channels.c.
4205 Removed the "Inviting xxx to channel" message from the
4206 client library away and let the application handle it.
4207 Affected file lib/silcclient/command.c. Added that message
4208 to Irssi SILC client's message formats.
4210 * Fixed CMODE command crash in client. It now checks the
4211 amount of arguments correctly and does not crash. The affected
4212 file is lib/silcclient/command.c.
4214 * Do not create new channel automatically in silc_channels_join
4215 but check whether the channel by that name already exists.
4216 Affected file irssi/silc/core/silc-channels.c.
4218 * Do not send the SERVER_SIGNOFF to router if the disconnected
4219 entity was the router. Affected file silcd/server.c.
4221 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4222 SILC client as it was missing from there.
4224 Added the handling of the KICK notify to the Irssi SILC client
4225 as it was missing. Added "you have been kicked" message to
4226 Irssi SILC client's message modules formats.
4228 Added the handing of the KILL notify to the Irssi SILC client
4229 as it was missing. Added the kill message module formats
4232 The affected file is irssi/src/silc/core/silc-channels.c.
4234 * The router did not save the channel mode the server announced.
4235 Affected file silcd/packet_receive.c.
4237 * Fixed a possible crash in INFO command in server. If the
4238 server did not provide the server info it crashed. Affected
4239 file silcd/command.c.
4241 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Fixed the GETKEY command in the server to check also the
4244 global list. Otherwise the GETKEY would not work correctly
4245 in normal SILC server. Affected file silcd/command.c.
4247 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4249 * Fixed GETKEY crash, it crashed if the command did not succseed.
4251 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4253 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4254 is now real and not just an macro interface to GMP.
4256 Removed the entire GMP from the source tree and imported new
4257 NSS MPI library instead. Reason for removing GMP is that it is
4258 extremely large and compiles extremely slow. The NSS MPI
4259 is only a few files and compiles in less than 10 seconds.
4260 The speed is also about the same as GMP. The MPI is imported
4261 to lib/silcmath/mpi.
4263 If the system has GMP installed we will still use the GMP.
4264 If it is not then the NSS MPI will be compiled.
4266 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4268 * Merged a long nickname (127 characters long) crash bugfix from
4269 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4271 * Merged a freed memory reference bugfix from Irssi CVS tree.
4272 Affected file irssi/src/core/commands.c.
4274 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Added the server's public key sving and verification to the
4277 server when performing the SKE. This was missing and the
4278 remote server's (or router's) public key was accepted without
4279 checking whether we have it previously or trust it at all.
4280 Affected file silcd/protocol.c.
4282 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Check in the silc_server_timeout_remote if protocol is active
4285 and make sure that the protocol's final callback is called so
4286 that all memory if freed. Affected file silcd/server.c.
4288 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * silc_server_whois_send_reply crashed the server if the nickname
4291 was 127 characters long. Affected file silcd/command.c.
4293 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Added sanity check to the silc_server_new_client. If the hostname
4296 is provided inside username then check that the provided hostname
4297 really is the same as the resolved one. If the hostname was not
4298 resolved then check it from the public key. Affected file is
4299 silcd/packet_receive.c.
4301 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4302 if the server disconnected us and the connection is not valid
4303 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4305 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4306 the library to the lib/silcutil/silcutil.[ch].
4308 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Close log file after open. Affected file
4311 lib/silcutil/silclog.c.
4313 * Check whether sock == NULL in silc_client_send_packet and return
4314 if it is. Affected file lib/silcclient/silcclient.c.
4316 * Check rec->entry == NULL in the Irssi SILC Client before
4317 sending the channel message. Affecte file is
4318 irssi/src/silc/core/silc-servers.c.
4320 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4322 * Merged a splitted window bugfix from Irssi CVS tree. The
4323 affected file is irssi/src/fe-text/textbuffer-view.c.
4325 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4326 It did not print nickname.
4328 * Improved the distributions system a bit.
4330 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4333 irssi/src/fe-text/gui-window.c.
4335 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4336 to in-active server. The affected file is
4337 irssi/src/silc/core/client_ops.c.
4339 * Resolve the client in USERS command reply if the entry does
4340 not have username resolved. The affected file is
4341 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4342 command to WHOIS command to really resolve stuff. The USERS
4343 is not used any more in any critical section so WHOIS can
4344 be used even though it might be slower than IDENTIFY.
4346 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4349 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4351 * Changed the protocol API a bit more consistent in the
4352 lib/silccore/silcprotocol.[ch].
4354 * Changed the following headers to ROBODoc format:
4356 lib/silccore/silcpayload.h
4357 lib/silccore/silcprotocol.h
4358 lib/silccore/silcsockconn.h
4360 All core library headers are now formatted.
4362 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Fixed a bug in Irssi SILC client; do not show that you are
4365 server/router operator if you really are not. Affected file is
4366 irssi/src/silc/core/client_ops.c.
4368 * Renamed silc_command_free_payload to silc_command_payload_free.
4369 Affected file lib/silccore/silccommand.h
4371 * Added silcmath.h to include the prototoypes of various routines
4372 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4375 * Changed the following headers to ROBODoc format:
4377 lib/silccore/silcchannel.h
4378 lib/silccore/silccommand.h
4379 lib/silccore/silcid.h
4380 lib/silccore/silcidcache.h
4381 lib/silccore/silcmode.h
4382 lib/silccore/silcnotify.h
4383 lib/silccore/silcpacket.h
4384 lib/silcmath/silcmath.h
4386 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Added checking to the server code not to start the server if
4389 ciphers and stuff are not configured properly. Affected files
4390 silcd/serverconfig.[h] and silcd/server.c.
4392 * Changed the layout of the header files of the public interfaces
4393 in the SILC libraries. The new layout supports ROBODoc
4394 documentation tool (and some others) so that it is easy to create
4395 a library reference manual. All the other headers and source
4396 code must still follow the CodingStyle document. Also source
4397 code must not include these ROBODoc stuffs, only the headers.
4398 Furthermore, all public interface headers must now be named
4399 by using `silc' prefix, example: silcapi.h, silccipher.h.
4400 Some files were renamed due to this. All the other headers
4401 must not be used as public interfaces. I will update the
4402 CodingStyle document later. Changed following headers, so far:
4404 lib/silcclient/silcapi.h
4405 lib/silccore/silcauth.h
4406 lib/silccore/silcprivate.h
4407 lib/silccrypt/silcdh.h
4409 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Removed silc_client_packet_send_flush from the client library
4414 as it is not needed. Affected file lib/silcclient/client.[ch].
4416 * Added printing of message of unresolved authentication method
4417 to the Irssi SILC client. Added it to the module formats.
4418 Removed the same message from the client library.
4420 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Added new distribution feature, DISTLABEL. Every distribution
4423 can define own preprocessor label that can be used in the
4424 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4425 file distributions, acconfig.h.pre and prepare.
4427 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Added Makefile.defines_int to include the actual definitions
4430 for Makefile.defines.in. Tested the new distribution system,
4431 created distributions and tested installation.
4433 * Added AWAY message printing to the Irssi SILC client. Added
4434 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4436 * Added SCONNECT command to call the SILC's CONNECT command.
4437 Cannot use CONNECT directly since Irssi uses that internally.
4438 Affected file irssi/src/silc/core/silc-servers.c.
4440 Added ACTION local command. It is same as ME command but takes
4441 the channel as mandatory argument.
4443 Rewrote some of the Irssi's help files to suite for SILC
4446 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Added Makefile.defines[.in] that should for now on be included
4449 in all Makefile.am file in the source tree. That file includes
4450 all common compilation definitions for SILC source tree.
4452 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4454 * Minor changes to the ./prepare script to change the package
4455 name according the distribution name to the configure.in.
4457 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Created new distribution system. Added file `distributions'
4460 that defines all the distributions that can be created out of
4461 the SILC source tree. The ./prepare script now reads that
4462 file to determine how to prepare the distributions. The
4463 first argument to the ./prepare is the name of the distribution
4464 and second is the version of the distribution. If given
4465 without arguments it creates the default (toolkit) distribution
4466 with the default version (defined in ./prepare).
4468 All Makefile.am files that are subject to the distributions
4469 are now named as Makefile.am.pre. These are ./Makefile.am
4470 and lib/Makefile.am. Others may be changed later.
4472 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Added invite list, ban list, some key management and connection
4475 error message printing to module formats in the Irssi SILC client.
4477 * Added new silc_client_set_away_message to set the away message
4478 that is back to the person who sent private message. The
4479 affected file lib/silcclient/silcapi.h and the
4480 lib/silcclient/client_prvmsg.c.
4482 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Fixed the private message sending in the Irssi SILC client,
4485 added local command KEY to the Irssi SILC client.
4487 Added key management and key agreement message formats to the
4488 irssi/src/fe-common/silc/module-formats.[ch].
4490 Added USERS (alias WHO) printing, server/router operator
4491 indication and LIST command printing to the module formats.
4493 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4495 * Fixed channel joining notify handling, cumode notify handling
4496 from Irssi SILC client.
4498 * Added SILC specific module-formats to the Irssi SILC client so
4499 that SILC specific message hilighting, colors etc is possible.
4500 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4502 Added channel mode, channel user mode, actions, notices,
4503 whois and whowas printing to the the module-formats.c.
4505 * Fixed a bug in channel deletion in the server. The channel
4506 is not left to the cache even if the channel founder auth mode
4507 is set when there are no users anymore on the channel. Affected
4508 file silcd/server.c.
4510 * The silc_net_localhost now resolves the entire hostname including
4511 the domain name. Affected file lib/silcutil/silcnet.c.
4513 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4515 * Changed the ask_passphrase client operation to be ascynchronous.
4516 It has now a completion callback and a context that the
4517 application must call after it has got the passphrase from
4518 the user. Affected files lib/silcclient/silcapi.h,
4519 lib/silcclient/protocol.c, lib/silcclient/command.c and
4522 Added SilcAskPassphrase callback that the application calls
4523 to deliver the passphrase to the library.
4525 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4526 The public key verification and especially a certificate
4527 verification is asynchronous procedure.
4529 Added new SILC_SKE_STATUS_PENDING status to indicate the
4530 request is pending and a callback will be called to finalize
4533 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4534 indicate that remote end did not send its public key (or
4535 certificate), even though we require it. Added check for this
4536 condition in the SKE. This was a security bug, now fixed.
4538 Defined new SilcSKEVerifyCbCompletion callback that is called
4539 when the verification process is completed.
4541 The affected files lib/silcske/silcske_status.h and
4542 lib/silcske/silcske.[ch].
4544 * Changed the verify_public_key client operation to be async
4545 as well. Defined SilcVerifyPublicKey callback that is used to
4546 indicate the success of the public key verification process.
4548 Changed the server and client to use the new async client
4551 * Changed the Irssi SILC client's internal scheduler to be called
4552 twice as many times as it used to be. As a result the client
4553 should be a bit faster now. Affected file is
4554 irssi/src/silc/core/silc-core.c.
4556 * Added support to Irssi SILC client of asynchronous public key
4557 verification and passphrase inquiry. Affected file is
4558 irssi/src/silc/core/silc-core.c.
4560 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Do not say "You have left channel %s" in client library.
4563 Moved it to the application. Affected files are
4564 lib/silcclient/command.c and silc/client_ops.c.
4566 * Fixed silc_client_get_clients. Command context was not
4567 duplicated and was freed memory in the callback. Affected
4568 file lib/silcclient/idlist.c.
4570 * Do not say "you are now talking..." on JOIN command in the
4571 client library. The appliation must handle it.
4573 * Do not say ".. changed topic to" in command reply in the
4574 client libary. The application must handle it.
4576 * Fixed TOPIC command sending in the client library.
4578 * Fixed a memory leak in silc_client_command_free in the file
4579 lib/silcclient/command.c.
4581 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4583 * Imported a modified version of Irssi client to the source tree.
4584 The Irssi will be used to create a new client called
4585 Irssi SILC. Imported to irssi/.
4587 Added silc_core_init_finish function to the Irssi. Affected
4588 file irssi/configure.in.
4590 A lot changes in the Makefile.ams around the irssi tree.
4592 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Do not rehash if the new size is same as the old size of the
4595 hash table, in the silc_hash_table_rehash*. The affected file
4596 lib/silcutil/silchashtable.c.
4598 * Replaced hash_table_del_by_context calls from the server
4599 (when channel->user_list and client->channels) to the
4600 hash_table_del as it is sufficient and faster.
4602 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Added silc_hash_table_list, silc_hash_table_get and the
4605 SilcHashTableList structure to provide an alternative way to
4606 traverse the hash table. The affected files are
4607 lib/silcutil/silchashtable.[ch].
4609 * Changed the server's idlist routines to use the hash table
4610 routines to optimize the code.
4612 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Replaced the client entry's `channel' list and channel entry's
4615 `user_list' list to hash tables for optimized lookup. Changed
4616 the code to use the hash table interface around the code.
4617 Affected file lib/silcd/idlist.[ch].
4619 * Added `auto_rehash' boolean argument to the function
4620 silc_hash_table_alloc to indicate whether the hash table should
4621 auto-rehash when it thinks is appropriate time. It will
4622 increase the hash table size if the there is twice as much
4623 entries in the table than the size of the table, and will
4624 decrease the size if there are twice as less entries than
4625 the size of the table.
4627 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4631 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * silc_idcache_purge_by_context deletes the entry now by context
4634 as it is supposed to do. Affected file lib/silccore/idcache.c.
4636 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4637 client is not anymore valid (WHOWAS givens the info) and not
4638 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4640 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Removed the `data' and `data_len' arguments from the ID Cache
4643 interfaces and added `name' argument. ID Cache does not handle
4644 anymore the binary data only a names associated with given ID.
4646 * When hashing a Client ID with silc_hash_id the entire ID is
4647 not hashed anymore, instead only the hash of the Client ID is
4648 hashed. This way we can access the Client ID from the cache
4649 with Client ID but with the hash of the ID (which is a hash of
4650 the nickname) as well without any difference in performance.
4652 Added also silc_idcache_find_by_id_one_ext to do one on one
4653 searching when we have the actual ID. Added also function
4654 silc_hash_client_id_compare. The affected files are
4655 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4657 * When hashing the name associated with a ID it is always done
4658 in lowercase. This way we can access the cache without worrying
4659 about case-sensitivity, even though, for example nicknames are
4662 * Fixed a bug in server with channel message sending. It put
4663 wrong ID type as destination ID. The affected file
4664 silcd/packet_send.c.
4666 * silc_idcache_del_by_context now deletes from all hash tables
4667 by context. Affected file lib/silccore/idcache.c.
4669 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4671 * Changed the client library to use the new ID Cache interface.
4672 Changes around the source tree.
4674 * Added silc_hash_table_rehash_ext to rehash with specific
4675 hash function. Affected file lib/silcutil/silchashtable.[ch].
4677 * Added silc_hash_string_compare to compare two strings in the
4678 hash table. Affected file lib/silcutil/silcutil.[ch].
4680 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4682 * Added new function silc_idcache_del_by_context into the
4683 lib/silccore/idcache.[ch].
4685 * Changed the server's ID list routines to use the new ID Cache
4686 interface. Changes around the source tree.
4688 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Added silc_hash_table_del[_by_context]_ext functions in to the
4691 lib/silcutil/silchashtable.[ch].
4693 Removed silc_hash_table_find_all* routines and added new
4694 silc_hash_table_find_foreach to replace them.
4696 Added silc_hash_table_replace_ext function as extended
4697 replacing function. Separated the simple hash table interface
4698 from the extended hash table interface in the file
4699 lib/silcutil/silchashtable.h.
4701 * Fixed minor bugs and changed it to use some of the new
4702 hash table functions in lib/silccore/idcache.c
4704 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Added new function silc_hash_table_find_all to return all keys
4707 in the hash table by the specified key. As the hash table is
4708 collision resistant it also makes it possible to have several
4709 duplicate keys in the hash table. This function may be used to
4710 find all of the keys from the hash.
4712 Added user_context arguments to the SilcHashFunction,
4713 SilcHashCompare and SilcHashDestructor to deliver user specified
4716 Added new fuctions silc_hash_table_find[_all]_ext to do
4717 extended lookup with specified hash and compare functions and
4718 specified user contexts.
4720 Added new function silc_hash_table_add_ext to add the key
4721 with specified hash function and user context.
4723 Added new function silc_hash_table_foreach to traverse all
4724 entrys in the hash table. Added SilcHashForeach callback
4727 Added new function silc_hash_table_del_by_context to delete
4728 the entry only if the context associated with the key matches.
4730 Affected files are lib/silcutil/silchashtable.[ch].
4732 * Removed silc_hash_[server/client/channel]_id and added just
4733 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4734 silc_hash_id_compare to compare two ID's using as the hash table
4735 comparison function. Added also silc_hash_data to hash
4736 binary data and silc_hash_data_compare to compare it.
4738 * Removed silc_idlist_find_client_by_hash as it is not needed
4739 anymore. Affected file silcd/idlist.[ch].
4741 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4742 to use internally the SilcHashTable. The new ID Cache is a lot
4743 faster than the old one. Some of the ID Cache interface was also
4744 rewritten and obsolete and stupid functions were removed.
4746 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4748 * Added entry_count field to the SilcHashTable to keep the number
4749 of the entries in the table. Implemented the function
4750 silc_hash_table_rehash. Added new function
4751 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4753 Fixed a minor bug in silc_hash_table_free.
4755 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4756 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4757 into the lib/silcutil/silcutil.[ch].
4759 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4761 * Implemented a collision resistant hash table into the
4762 lib/silcutil/silchashtable[ch]. See the header and the source
4763 for the SilcHashTable API.
4765 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4767 * Merged dotconf version 1.0.2 into lib/dotconf.
4769 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Do not compile anything in lib/silcsim/* if the SIM support
4772 is not enabled. The tree should now compile without problems
4775 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Compiled the SILC under cygwin. Compiled and tested briefly
4778 without problems. More tests needed. The SIMs didn't compile
4781 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4783 * Fixed possible crash in silc_get_username in the
4784 lib/silcutil/silcutil.c.
4786 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4788 * Fixed a va_arg in silc/client_ops.c.
4790 * Oops, RC5 routines were named AES and caused some problems
4791 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4793 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Added new SilcIDIP structure into the lib/silccore/id.h and
4796 replaced the old `ip' fields from all SILC ID's to that type.
4797 This is a step towards IPv6 support.
4799 The silc_id_get_len takes now the ID as an extra argument.
4800 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4801 both IPv4 and IPv6 based ID's.
4803 The affected files are lib/silccore/id.[ch] and other files
4804 around the tree using these routines.
4806 * Removed the ID length arguments in server from various
4807 silc_server_send_notify_* routines -> they are not needed
4810 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4812 * Fixed memory leak in silc_encode_pem_file in the file
4813 lib/silcutil/silcutil.c.
4815 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4817 * Check minor version as well in the SKE. Affected files are
4818 silcd/protocol.c and lib/silcclient/protocol.c.
4820 * Added --identifier option to the server so that an identifier
4821 can be when creating the public key for the server. Affected
4822 file is silcd/silcd.c.
4824 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4825 lib/silccrypt/silcpkcs.c.
4827 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Register default ciphers and stuff when using -C option with
4830 the server. Affected file sildc/silcd.c.
4832 * Put back the servers public key filename format, it is better
4833 than the new one. For now, the client keys are saved with the
4834 new filename format. The affected file silc/client_ops.c.
4836 * Implemented the Cipher API for the rest of the ciphers that
4837 did not implement it or implemented it the wrong way.
4839 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Register default ciphers and stuff when using the -S option
4842 in the client. Affected file silc/silc.c. Same also when
4843 creating new key pair with -C option.
4845 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Fixed the silc_verify_public_key client operation function to
4848 save the public keys differently. The fingerprint is now
4849 used as filename and not the hostname. This way also the
4850 client keys are saved uniquely and not with hostnames. The
4851 affected file is silc/client_ops.c.
4853 * Trimmed the silc_hash_fingerprint function to remove extra
4854 whitespaces from the end of the fingerprint. The affected
4855 file is lib/silccrypt/silchash.c.
4859 * Added silc_cipher_register_default function to register all
4860 default ciphers. It can be used when configuration files
4861 does not exist and the application does not want any specific
4862 ciphers in any specific order.
4864 The SilcDList is now used as silc_cipher_list dynamically
4865 allocated cipher list. Removed the static list all together
4866 and now all ciphers must be allocated to the dynamic list.
4867 The silc_cipher_alloc routine was changed to check only the
4870 All silc_cipher_* routines that used to return int returns
4873 The affected files lib/silccrypt/silccrypt.[ch].
4875 * The same thing was done to silc_hash_* as for silc_cipher_*
4876 routines. Affected files lib/silccrypt/silchash.[ch].
4878 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4879 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4880 Added also silc_pkcs_[un]register[_default] functions.
4881 Removed the data_context from the PKCS API.
4883 * Added silc_hmac_register_default function to register default
4884 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4885 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4886 to unregister all hmacs at once.
4888 * Register the default ciphers, hash functions, PKCSs and HMACs
4889 if client's configuration file does not exist. The affected
4892 * The client did not load the hash functions from the SIM
4893 modules at all. Added support for this. Affected file is
4894 silc/clientconfig.c.
4896 * When decoding public key with silc_pkcs_public_key_decode, check
4897 the supported algorithm only if PKCS are registered. Affected
4898 file lib/silccrypt/silcpkcs.c. The same was done with the
4899 silc_pkcs_private_key_decode.
4901 * Fixed the SILC List routines to keep the list always in order.
4902 It used to change the list's order when traversing the list but
4903 not it preserves the order. Affected file lib/trq/silclist.h.
4905 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Added the client library to use the SilcSocketConnection's
4908 reference counter (by silc_socket_dup) to prevent the bug that
4909 the socket object may be freed underneath async operation.
4911 * The name resolv library checking fixes in the configure.in.pre.
4914 * Created new version of the protocol drafts for future
4915 development. The -03 drafts are the ones that will be changed
4916 in the trunk now and the -02 will remain as they are.
4918 * Send list of CUMODE notifys to the router when announcing
4919 the channel users to the router. Affected file silcd/server.c.
4920 If the router receiving channel founder CUMODE for a channel
4921 that already has channel founder it will send CUMODE notify
4922 to the sender to remove the channel founder rights from the
4923 announced client. Affected file silcd/packet_receive.c.
4925 * The CUMODE notify may now use Server ID as well as the entity
4926 who changes the mode. Updated protocool specs.
4928 * Updated INSTALL and README files.
4930 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * New web pages in the http://silc.pspt.fi. The pages was
4937 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4939 * Implemented the [DenyConnectin] config section in the server.
4940 Added silc_server_config_denied_conn to check whether incoming
4941 connection is denied. Affected file silcd/serverconfig.[ch].
4943 * Do not check the ports when checking the incoming configuration
4944 data if the port is 0, meaning any. Affected file is
4945 silcd/serverconfig.c.
4947 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4949 * Fixed buffer overflow in silc_string_compare in the file
4950 lib/silcutil/silcutil.c.
4952 * Fixed double free in silc_server_command_leave in the file
4955 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4957 * Fixed the version checking in the server. Affected file is
4960 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Fixed the configuration data fetching when accepting new
4963 connections in the server. Affected file silcd/server.c.
4965 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * Added `sender_entry' argument to the function
4968 silc_server_packet_relay_to_channel so that we can check
4969 whether some destination actually belongs to the same route
4970 the sender belongs (ie, we must not resend the packet to the
4971 sender). Affected file silcd/packet_send.[ch].
4973 * Added `servername' field to the SilcClientEntry in the server
4974 to hold the name of the server where client is from. Affected
4975 file is silcd/idlist.h.
4977 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4979 * Moved the channel message encrypting in the router betwen
4980 router connections from silc_server_channel_message to the
4981 silc_server_packet_relay_to_channel since we want to check
4982 whether we have anybody channel before encrypting anything.
4983 Affected files silcd/packet_[receive/send].c.
4985 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4987 * Fixed the [AdminConnection] server config section to support
4988 multiple entries. Affected file silcd/serverconfig.c.
4990 * Added support into the server to check the validity of the
4991 incoming connection before executing any KE or authentication
4994 * The connection configuration is now saved to the KE and
4995 connection auth protocol contexts and not fetched anymore in
4996 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4998 * The local hosts listenning address and port is also resolved
4999 now when starting the server. We want to have the socket object
5000 to include the real address and port for the listener. Added
5001 new function silc_net_check_local_by_sock into the files
5002 lib/silcutil/silcnet.[ch].
5004 * Fixed a broadcast bug in server -> do not broadcast if we
5007 * Fixed a routing bug. Do not route broadcast packets ever.
5008 Broadcast packets must be processed always and not routed since
5009 they may be destined to some other host than yourself and thus
5010 would get routed without no good reason. Affected file is
5013 * Added function silc_server_config_is_primary_route to check
5014 whether primary router connection has been configured (a router
5015 configuration that we are initiating). If there is not, we
5016 will assume that there is only two routers in the SILC network
5017 and we will use the incoming router connection as our primary
5018 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5020 * Changed the order of the broadcasting. Broadcast _after_ the
5021 packet has been processed not before. Affected file is
5024 * Fixed a [ClientConnection] parsing bug. The port was never
5025 parsed correctly thus resulting to port 0. Affected file
5026 silcd/serverconfig.c.
5028 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5029 argument and did not set the broadcast packet flag. Affected
5030 file silcd/packet_send.c. Fixed same bug in the function
5031 silc_server_send_notify as well.
5033 * If we receive NEW_ID packet for our own ID in the server, ignore
5036 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Removed the nickname from the Private Message Payload.
5041 Updated the code and the protocol specs.
5043 * Updated protocol specs for submitting to the IETF.
5045 * Tweaked the Random Number Generator a bit. Affected file
5046 lib/silccrypt/silcrng.c. Exported a new function
5047 silc_rng_[global]_add_noise which can be used to add more
5050 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Do not parse packets with different timeout when protocol
5053 is active -> may cause problem with rekey. Affected file
5056 * When server receives signoff notify it must not create
5057 new channel key if the client is on any channels since the
5058 sender of the signoff notify will create it.
5060 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Added printing of error messages during SKE protocol from the
5063 failure packet sent by server during SKE. Affected file
5066 * Removed the client's failure_callback handling with timeout
5067 and handle it immediately when received.
5069 * The SKE library returned wrong type in SUCCESS and FAILURE
5070 packets. They must be 32 bit MSB not 16 bit MSB.
5072 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Ok, rewrote the logic of the re-key and now it seems to work.
5075 I tested it on high traffic with frequent re-keys without
5076 problems. Added hmac_receive (and renamed hmac to hmac_send)
5077 in SilcClientConnection in lib/silcclient/client.h and
5078 in SilcIDListData in silcd/idlist.h. Also, removed the
5079 SilcPacketParserContext's cipher and hmac fields as they are
5080 not needed anymore and actually caused some problems when
5081 the ciphers and hmac's changed underneath the packet parser.
5083 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5085 * If re-key protocol is active then process the incoming packets
5086 synchronously since we must assure that icoming packets encrypted
5087 with the old key is processed before the new keys is set to
5088 use. This is true other packets than for REKEY packets.
5089 Affected file silcd/server.c. The same was done to client library
5090 as well, affected file lib/silcclient/client.c.
5092 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Fixed bug in client and server to accept the force send if
5095 the packet is send from silc_[server/client]_packet_process
5096 function. Otherwise the packets are never delivered, oops.
5098 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5100 * Disable force sending of packets when REKEY protocol is active.
5101 We must assure that no packet is sent directly when rekey is
5102 performed. All packets must be sent through packet queue.
5103 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5104 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5105 function is silc_[server/client]_packet_send_real to check
5108 * Replaced the SIM paths from example config files to
5109 /usr/local/modules. Also, make install creates now
5110 /usr/local/silc/logs directory to hold all the SILC server
5113 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Made the configure.in.pre work on Solaris. Patch by salo.
5117 * Made all ciphers compatible with non-x86 machines. Defined
5118 CBC mode macros into lib/silccrypt/ciphers_def.h.
5120 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Fixed the make install.
5124 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5126 * When MAC computation fails the silc_packet_decrypt returned 0
5127 even though it was supposed to return -1. Fixed this. The
5128 affected file is lib/silccore/silcpacket.c.
5130 * Do not replace the config files in /etc/silc (in make install)
5131 if they already exist. Affected file ./Makefile.am.
5133 * Do not send re-key packets immediately but through packet queue.
5134 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5136 * Changed silc_net_check_host_by_sock to return FALSE if the
5137 IP/DNS could not be resolved. Though, it returns the IP address
5138 now even if it could not resolve it (but returns also FALSE).
5139 Affected file lib/silcutil/silcnet.[ch].
5141 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Added silc_pkcs_decode_identifier to decode the public key's
5144 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5145 Added also silc_pkcs_free_identifier. Added also new context
5146 SilcPublicKeyIdentifier.
5148 * Added -S option to the silc client. It is used to dump the
5149 contents of the specified public key file.
5151 * Changed the PKCS api to return the public key length when
5152 setting the public key.
5154 * Fixed a fatal bug in the public and private key file loading.
5155 Affected file lib/silccrypt/silcpkcs.c.
5157 * Execute the packet parsing for client with zero (0) timeout
5158 if the protocol is active. Affected file silcd/server.c.
5160 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Made the key generation options to the silcd program. Added
5163 -C option, equivalent to client's option.
5165 * Added new [ServerKeys] config section to the server. It
5166 configures the server's public and private key.
5168 * Defined generic Public Key Payload into the protocol
5169 specification to send specific type of public keys and
5172 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5173 public key or certificate.
5175 * Implemented the GETKEY command to the server and to the
5176 client library and on user interface.
5178 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Made preliminary `make install' work.
5182 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Added SilcServerRekey context into silcd/idlist.h.
5186 * Added the PFS support as defined in the specification to the
5187 SKE protocol. Affected files lib/silcske/*.c.
5189 * Added `ske_group' field to the SilcServerRekey context to hold
5190 the number of the SKE group that is used with PFS in re-key.
5191 Affected file silcd/idlist.h.
5193 * Added PFS re-key support to the server. Affected file is
5196 * Added silc_protocol_cancel to cancel execution of the next
5197 state of the protocol. Affected file is
5198 lib/silccore/silcprotocol.[ch].
5200 * Added the re-key support with and without PFS to the client
5201 library. Re-key is performed once in an hour, by default.
5203 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5204 Added silc_client_rekey_callback and silc_client_rekey_final.
5205 Affected files are lib/silcclient/protocol.[ch] and
5206 lib/silcclient/client.[ch].
5208 * Removed the `hmac_key' and `hmac_key_len' fields from the
5209 SilcClientConnection structure; not needed. Affected file is
5210 lib/silcclient/client.h.
5214 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Do not ask whether user wants to use the negotiated private key
5217 for private messages, just use it. Affected file is
5218 silc/local_command.c.
5220 * Added `send_enc_key' and `enc_key_len' fields to the
5221 SilcIDListData structure since they are needed in the re-key
5222 phase. Affected file is silcd/idlist.[ch].
5224 * Implemented the simple re-key protocol into the server.
5225 Affected files silcd/server.c and silcd/protocol.[ch]. The
5226 re-key will be performed once in an hour, by default.
5228 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5229 Added silc_server_rekey, silc_server_rekey_callback and
5230 silc_server_rekey_final.
5232 * Removed Tunneled flag from the protocol. Updated the code
5233 and the specifications.
5235 * Adde `pfs' field to the SilcIDListData to indicate whether
5236 the PFS is to be performed in the re-key. Affected file is
5239 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5242 int64 of at least the xintXX size. If void * is less that 4
5243 bytes uint32 * will be used. Defined bool as boolean.
5245 * Changed _ALL_ unsigned long and unsigned int to uint32,
5246 unsgined short to uint16 in the source tree.
5248 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5249 not handle clients that has entry->data.registered == FALSE.
5250 They are not in the network anymore. Affected file is
5253 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Implemented the sending of the SERVER_SIGNOFF notify in the
5256 server. Affected file is silcd/server.c.
5258 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5259 Added also silc_notify_payload_encode_args into the
5260 lib/silccore/silcnotify.[ch].
5262 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5263 Affected file silcd/packet_receive.c.
5265 * Implemented the SERVER_SIGNOFF notify handling in the client
5266 library. Affected file lib/silcclient/client_notify.c. Also,
5267 implemnted the printing of the SERVER_SIGNOFF info to the
5268 application. Affected file silc/client_ops.c.
5270 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5271 if the deleting was successful. Affected file silcd/idlist.[ch].
5273 * Added support for public key authentication in the connection
5274 authentication protocol in the client library. Affected file
5275 lib/silcclient/protocol.c.
5277 * Changed the server's silc_idlist_get_clients_by_* interface
5278 to support already allocated array so that new entries may be
5279 added to pre-allocated array. Affected file silcd/idlist.[ch].
5280 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5281 and command replies.
5283 * All command reply functions in the server now calls the
5284 pending command callback even if error occured. This way the
5285 error will be delivered to the client as well. Affected files
5286 silcd/command.c and silcd/command_reply.c.
5288 * Fixed INFO command to return local server's info if no server
5289 was provided. Affected file lib/silcclient/command.c.
5291 * Removed RESTART command for good. Updated the code and the
5294 * Rewrote parts of the task system. It is a bit simpler now.
5295 Removed unsued task priorities. The affected files are
5296 lib/silcutil/silctask.[ch].
5298 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Moved the USERS printing from the library to the application.
5301 Affected files lib/silcclient/command.c and silc/client_ops.c.
5303 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added channel key re-key support. The re-key is perfomed
5308 only by the router and is done once in an hour. Added `rekey'
5309 field to the SilcChannelEntry in the server. Affected files
5310 silcd/server.c and silcd/idlist.h.
5312 * Added silc_task_unregister_by_context into the file
5313 lib/silcutil/silctask.[ch].
5315 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5317 * Added SILC_UMODE_GONE mode to indicate when the client is not
5318 present in the SILC network. Added also support to the local
5319 command AWAY that will set this mode. Added support of showing
5320 "xxx is gone" in WHOIS command. The USERS command shows the
5321 gone status as well.
5323 * Fixed setting server and router operator privileges in the
5324 server's UMODE command. Affected file silcd/command.c.
5326 * Merged the SKE KE1 and KE2 payloads into one payload. The
5327 new KE payload is equivalent to the old KE2 payload.
5329 Cleaned up the SKE Start Payload parsing. It now uses the
5330 simple buffer unformatting to do the parsing. A lot faster
5333 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5334 to the SKE that is used to indicate whether both of the SKE
5335 parties should perform authentication. By default only the
5336 responder performs authentication. By setting this flag also
5337 the initiator must do authentication. By default it is unset
5338 since in normal SKE case, client to server connection, only
5339 the responder should do authentication. When doing SKE between
5340 two clients both should perform authentication. Updated the
5341 code and the protocol specs.
5343 * A little fix to IDENTIFY command in the server. Search the
5344 client first by hash not nickname. Affected file is
5347 * Fixed the silc_client_close_connection to support closing
5348 the client to client connections wihtout deleting too much
5349 data. Affected file lib/silcclient/client.c.
5351 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5352 are received if protocol used to be active but is not anymore
5353 the application would crash due to NULL pointer dereference.
5354 Affected files silcd/server.c and lib/silcclient/client.c.
5356 * Added `hash' field to the SilcClientConnection to include
5357 the hash function negotiated in the SKE protocol.
5359 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5360 to set the channel founder authentication data. A client can
5361 claim the founder rights later by providing the authentication
5362 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5363 This way the channel founder can regain the channel founder
5364 privileges even it is left the channel. This works only on
5365 local server and the client must be connected to the same
5366 server to be able to regain the founder rights. Updated the
5367 protocol specs accordingly.
5369 Added support to the CMODE command in the client to set the
5370 founder auth data. Read the README to see how to set it.
5372 Added support to the CUMODE command to claim the founder
5373 rights. Read the README to see how to do it.
5375 Added support for the founder authentication to the Channel
5376 Entry in the server. Affected file silcd/idlist.h.
5378 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5379 server's CMODE command. Affected file silcd/command.c.
5381 * Added the following new functions into lib/silccore/silcauth.[ch]:
5382 silc_auth_get_method and silc_auth_get_data.
5384 * The server now saves the remote hosts public key to the
5385 SilcIDListData pointer. Affected file silcd/protocol.c.
5387 * The normal server now does not remove the channel entry from
5388 the cache if the founder authentication data is set. It used
5389 to remove it if the founder was the last one on the channel on
5390 the server and left the channel. The auth data is saved and
5391 if the channel is re-joined later the old entry is used with
5392 the old auth data. Affected files silcd/command_reply.c and
5395 * Removed the `pkcs' field from the SilcIDListData structure
5396 in the server; it is not used. Affected file silcd/idlist.h.
5398 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Fixed packet processing on slow links. Partial packets were
5401 never re-processed because the incoming data buffer was cleared
5402 by the application. Application must not directly clear the
5403 sock->inbuf, the packet processing routines handle it. Fixed
5404 this in client library and in server.
5406 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Fixed the WHOIS and IDENTIFY send reply function to really
5409 check whether to send list or just one entry. Affected file
5412 * Cleaned up the LEAVE command's channel key distribution. The
5413 affected file silcd/command.c.
5415 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5416 can enforce the channel mode as well. In that case the ID
5417 includes the ID of the server. The code now enforces the
5418 mode change if the router have different mode than the server.
5420 * The notify client operation with CMODE_CHANGE notify can now
5421 return NULL client_entry pointer if the CMODE was not changed
5422 by client. Application must check for this.
5424 * Added <Server ID> argument to INFO command to support server
5425 info fetching by Server ID.
5427 * Added silc_server_announce_get_channel_users to get assembled
5428 packets of channel users of the specified channel. Affected
5429 file silcd/server.[ch].
5431 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5432 was freed underneath the ID Cache.
5434 * Re-announce clients when the server received CHANNEL_CHANGE
5435 notify from the router. Affected file silcd/packet_send.c.
5437 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5440 crashed since it did not handle the fact that there is no cipher
5441 called "3" and didn't check the error condition. Now fixed.
5443 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5444 flag. It can be used to send message requests.
5446 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Implemented the RESTART command in the client.
5450 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5451 notice type messages. Added notice printing to the user
5454 * The channel keys are not re-generated if the channel's mode
5455 is PRIVKEY, ie private key on the channel exists. Affected
5456 files silcd/server.c and silcd/command.c.
5458 * Fixed a little bug in channel message delivery when channel
5459 private keys are set in the server. Affected file is
5460 silcd/packet_send.c.
5462 * Changed the setting on channel->on_channel = TRUE from the
5463 silc_client_save_channel_key to the JOIN command reply. The
5464 key payload is not received if the private channel key is set.
5465 Affected file lib/silcclient/command_reply.c and the
5466 lib/silcclient/client_channel.c.
5468 * When the CMODE_CHANGE notify is sent and the channel private
5469 key mode is removed the channel key must be re-generated in
5470 other cells as well. Added this support for the router in the
5471 silcd/packet_receive.c.
5473 * Added new local command NOTICE to send notice message on
5474 channel. Affected file silc/local_command.[ch].
5476 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Added new local command ME to the client. It is used to send
5479 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5480 some action. Affected file silc/local_command.[ch].
5482 * Changed channel_message and private_message client operations
5483 to deliver the message flags to the application. Added also
5484 the `flags' arguments to the silc_client_send_channel_message
5485 and silc_client_send_private_message functions. Affected file
5488 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Redefined the Private Message Payload to support private message
5491 keys and to support the new private message flags. Updated
5492 the protocol specs. Flags makes it possible to have for example
5493 CTCP style messages.
5495 * Added new type SilcPrivateMessagePayload and defined an API
5496 for it in the lib/silcclient/silcprivate.[ch].
5498 * Tested private message private keys successfully. Tested the
5499 private message key set, unset and list commands with the new
5502 * Redefined the Channel Message Payload to include the channel
5503 message flags (equal with private message flags) to support
5504 for example CTCP style messages.
5506 * Defined some of the message (for channel and private message)
5507 flags. Updated the protocol specs and added the flags to the
5508 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5510 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Added SilcKeyAgreementStatus type to the key agreement routines
5513 to indicate the current status and error if one occured.
5514 The status types are defined in the lib/silcclient/silcapi.h.
5516 * Added new local command KEY that is used to set and unset private
5517 keys for channels, set and unset private keys for private messages
5518 with remote clients and to send key agreement requests and
5519 negotiate the key agreement protocol with remote client. The
5520 key agreement is supported only to negotiate private message keys,
5521 it currently cannot be used to negotiate private keys for channels,
5522 as it is not convenient for that purpose.
5524 * Fixed a minor pending callback setting bug in the function
5525 silc_client_get_client_by_id_resolve, now the function works.
5526 Affected file lib/silcclient/idlist.c.
5528 * Added function silc_net_get_local_port to get local bound
5529 port by socket. Added to lib/silcutil/silcnet.[ch].
5531 * Added `sockets' and `sockets_count' fields to the SilcClient
5532 object. They hold the sockets of the listenning sockets in
5533 the client. Listenning sockets may be for example the key
5534 agreement server. Affected file lib/silcclient/client.[ch].
5535 Added functions the silc_client_add_socket and the
5536 silc_client_del_socket. They are exported to the application
5539 * Added ~./silc/clientkeys to support other client's public keys.
5541 * Renamed verify_server_key client operation to verify_public_key
5542 and added one argument to indicate the type of the connection
5543 (server, client etc.).
5545 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Added silc_server_connection_auth_request to handle the
5548 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5549 silcd/packet_receive.[ch].
5551 * Added silc_server_send_connection_auth_request into the
5552 silcd/packet_send.c to send the connection auth request packet.
5554 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5557 * Fixed the public key authentication in responder side in the
5558 server. The `auth_data' pointer includes the SilcPublicKey
5559 not the path to the public key. Affected file silcd/protocol.c.
5561 * Implemented the public key authentication in the initiator side
5562 in the server. Affected file silcd/protocol.c.
5564 * Removed the [RedirectClient] config section from the server
5565 configuration. Is not needed and I don't want to implement it.
5567 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Cleaned up the CMODE command in the server. It now works
5570 correctly and supports all the modes defined in the protocol.
5571 Affected file is silcd/command.c.
5573 * Added `hmac_name' field to the SilcChannelEntry in the server
5574 to hold the default HMAC of the channel. It can be set when
5575 creating the channel (with JOIN command). Affected files
5578 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5579 type to indicate the change of the current cipher and hmac
5580 on the channel. Client can safely ignore the <cipher> argument
5581 (if it chooses to do so) since the CHANNEL_KEY packet will
5582 force the channel key change anyway. The <hmac> argument is
5583 important since the client is responsible of setting the new
5584 HMAC and the hmac key into use.
5586 * Fixed the CMODE command in the client library as well.
5588 * Tested CMODE command in router environment successfully.
5590 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Show the version of the remote client (or server) when connecting
5593 to the server. It is logged to the log file. Affected file
5594 is silcd/protocol.c.
5596 * Fixed the KILLED notify handling in the client library. The
5597 client must be removed from all channels when receiving the
5600 Also, do not remove the client entry when giving the KILL
5601 command but when the KILLED notify is received.
5603 * Removed silc_idlist_find_client_by_nickname from the server.
5604 Not needed anymore. Affected files silcd/idlist.[ch].
5606 * Implemented the CHANNEL_CHANGE notify type handling to the
5607 server. Affected file silcd/server.c.
5611 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5613 * Added silc_server_send_notify_invite to send the INVITE
5614 notify between routers.
5616 * Implemented the INVITE command correctly to the server.
5618 * Implemented the INVITE notify type handling in the server.
5620 * Implemented the INVITE command to the client library and on the
5623 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * Added function silc_server_get_client_resolve to find the
5626 client entry by ID from all ID lists and then resolve it
5627 (using WHOIS) if it cannot be found. Affected file is
5630 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Implemented the BAN command to the client library.
5634 * The JOIN command in the server now checks the invite list
5637 * Changed the silc_command_reply_payload_encode_va and the
5638 silc_command_payload_encode_va to support that if argument is
5639 NULL it ignores and checks the next argument. Affected file
5640 lib/silccore/silccommand.c.
5642 * Added silc_server_send_notify_ban to send the BAN notify
5643 type between routers.
5645 * Chaned the silc_notify_payload_encode to support that if
5646 argument is NULL it ignores and checks the next argument.
5647 Affected file lib/silccore/silcnotify.c.
5649 * Tested ban lists in router environment successfully.
5651 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * Implemented BAN command to the server, in silcd/command.[ch].
5655 * Removed the BAN and INVITE_LIST modes from the CMODE command
5658 * Added function silc_string_match to regex match two strings.
5659 Affected files lib/silcutil/silcutil.[ch].
5661 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5663 * Redefined parts of the SilcChannelEntry in the server to support
5664 the new ban and invite lists.
5666 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Redefined the INVITE command. The same command can be used to
5669 invite individuals to the channel but also to manage the invite
5670 list of the channel (to add to and remove from the invite list).
5671 Updated the protocol specs.
5673 * Added new command SILC_COMMAND_BAN that can be used to manage
5674 the ban list of the channel. Updated the protocol specs.
5676 * Removed the channel modes: the SILC_CMODE_BAN and the
5677 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5678 in the CMODE command. The equivalent features are now available
5679 using INVITE and BAN commands. Updated the protocol specs.
5681 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5682 in the network about change in the current ban list. The notify
5683 type is not used by the client.
5685 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5686 support the invite lists.
5688 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Added new function silc_string_regexify that converts string
5691 including wildcard characters into regex string that can
5692 be used by the GNU regex library. Added into the file
5693 lib/silcutil/silcutil.[ch].
5695 Added silc_string_regex_combine to combine to regex strings
5696 into one so that they can be used as one regex string by
5697 the GNU regex library. Added into the file
5698 lib/silcutil/silcutil.[ch].
5700 Added silc_string_regex_match to match two strings. It returns
5701 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5703 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5705 * Imported GNU regex to the soruce tree into lib/contrib.
5706 Fixed some compiler warning from the regex.c.
5708 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Fixed MOTD command in the server to work in router environment.
5712 * Fixed the MOTD command in the client library to support
5713 the server argument in the command.
5715 * Added `nickname_len' argument to the silc_idlist_add_client
5716 in the server, as the `nickname' argument may be binary data
5719 * Added silc_idlist_get_channels to return all channels from
5722 * Implemented LIST command to the server. Affected file is
5725 * Implemented the LIST command to the client library and on the
5728 * Added [<user count>] argument to the LIST command reply.
5729 With private channels the user count is not shown.
5731 * Updated TODO and README.
5733 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * The client entry's data.registered must be TRUE even with
5736 global client entry on global client list. The data.registered
5737 is used to check whether the client is anymore in the network,
5738 for example with WHOWAS command so it must be valid.
5740 * Fixed the WHOWAS command in the server. It now actually works
5741 in router environment. Added function into silcd/command_reply.c
5742 silc_server_command_reply_whowas_save.
5744 * Added silc_idlist_purge function to the silcd/idlist.c
5745 to periodically purge the ID Cache.
5747 * Fixed INFO command in the server. It works now in router
5748 environment. Added <server name> argument to the INFO command
5749 reply. Updated the protocol specs.
5751 * Fixed minor bug in silc_idcache_purge to not purge if the
5752 expire value is zero.
5754 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5755 they were buggy because of the WHOWAS information.
5757 * Fixed local command MSG to handle the async resolving of
5758 the remote client properly. It used to fail the first MSG.
5759 Affected file silc/local_command.c.
5761 * Added `data_len' field to SilcIDCache context.
5763 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Update TODO. Todo in commands in the server.
5767 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5770 used by routers as broadcast packet to inform other routers
5771 about the changed user mode.
5773 Implemented the notify handling in the server. Affected file is
5774 silcd/packet_receive.c. Added the function
5775 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5777 * Added new generic Channel Payload and deprecated the New Channel
5778 Payload. The New Channel Payload is now the generic Channel
5781 * Added new argument `mode' to the silc_server_send_new_channel
5782 as it is required in the Channel Payload now.
5784 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5785 and created a new and real SilChannelPayload to represent the
5786 new generic Channel Payload. Implemented the encode/decode
5787 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5789 * Added silc_server_get_client_channel_list to return the list
5790 of channels the client has joined for WHOIS command reply.
5791 Affected file silcd/server.[ch].
5793 * Implemented the channel list sending in the WHOIS command reply
5794 in server and in the client.
5796 Implemented the channel list displaying on the user interface
5797 as well. Affected file silc/client_ops.c.
5799 * Added silc_channel_payload_parse_list to parse list of Channel
5800 Payloads. It returns SilcDList list of SilcChannelPayloads.
5801 Client for example can use this function to parse the list of
5802 channels it receives in the WHOIS command reply. The caller
5803 must free the list by calling silc_channel_payload_list_free.
5804 Affected files lib/silccore/silcchannel.[ch].
5806 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Added one new argument <user mode> to the WHOIS command reply
5809 to return the mode of the user in SILC. Updated the protocol
5812 Implemented it to the server and client.
5814 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Fixed the mode printing on the user interface on joining.
5817 Affected file silc/client_ops.c.
5819 * Implemented the UMODE command and user modes in general to the
5820 client library and to the user interface.
5822 * Implemented the UMODE command to the server.
5824 * The server now sends UNKNOWN_COMMAND error status if client sends
5825 unknown command. Affected file silcd/command.c.
5827 * All server commands now handle the command identifier the right
5828 way when sending the command reply to the client. The client can
5829 use to identify the command replies with the identifier.
5831 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5833 * Added silc_server_get_client_route to resolve the route to
5834 the client indicated by the client ID. Affected file is
5837 * Added silc_server_relay_packet as general function to relay
5838 packet to arbitrary destination. This deprecates functions
5839 like _send_private_message_key, _relay_notify etc. Affected
5840 file is silcd/packet_send.[ch].
5842 Removed silc_server_send_key_agreement,
5843 silc_server_send_private_message_key and
5844 silc_server_packet_relay_notify functions from the file
5845 silcd/packet_send.[ch].
5849 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5850 server. Affected file silcd/packet_receive.[ch].
5852 * Implemented the KILL command to the client. Implemented the
5853 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5854 Affected files lib/silcclient/command[_reply].c and
5855 lib/silcclient/client_notify.c. Implemented the KILL notify
5856 printing in the user inteface.
5858 * Fixed a lot silc_parse_nick memory leaks from the client
5859 library in the file lib/silcclient/command.c.
5861 * Changed the silc_server_send_notify_on_channels's `sender'
5862 argument from SilcSocketConnection to SilcClientEntry to
5863 check the sender as entry and not as connection object and not
5864 to send to the client provided as argument. The affected file
5865 is silcd/packet_send.[ch].
5867 * The notify packets that are destined directly to the client used
5868 to not to be processed by the server. Now changed that and the
5869 server processes all notify packets. After relaying the packet
5870 to the client the notify packet is processed in the server.
5872 * The silc_server_free_client_data now checks whether there is
5873 pending outgoing traffic for the client and purges the data to
5874 the network before removing the client entry.
5876 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5879 an client is killed from the SILC Network. Updated the protocol
5882 Added new function silc_server_send_notify_killed to the
5883 silcd/packet_send.[ch].
5885 * Added function silc_server_packet_relay_notify to relay notify
5886 packets that are destined directly to a client. In this case
5887 the server does not process the notify packets but merely relays
5888 it to the client. Affected file silcd/packet_send.[ch].
5890 Added also silc_server_packet_process_relay_notify to check
5891 whereto relay the notify. Affected file is
5892 silcd/packet_receive.[ch].
5894 * Implemented the KILL command to the server.
5898 * Added the backup schema desgined last fall to the protocol
5899 specs for everyone to see. The specification is in the
5900 *-spec-xx.txt draft and the packet type definitions for the
5901 backup routers is in *-pp-xx.txt draft. Thusly, added also
5902 new packet type SILC_PACKET_CELL_ROUTERS.
5904 * A big security problem in the implementation discovered. The
5905 signoff of an client did not cause new channel key generation
5906 which it of course should've done. The channel keys must be
5907 always re-generated when client leaves (or signoffs) the channel.
5908 The silc_server_remove_from_channels funtion now handles
5909 the channel key re-generation.
5911 * Added `sender' argument to the silc_server_send_notify_on_channels
5912 to not to send the client provided as argument. Affected file
5913 silcd/packet_send.[ch].
5915 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Implemented OPER and SILCOPER commands into the server and
5920 * Added silc_auth_verify and silc_auth_verify_data to verify
5921 the authentication directly from the authentication payload.
5922 It supports verifying both passphrase and public key based
5923 authentication. Affected file lib/silccore/silcauth.[ch].
5925 * Added `hash' field to the SilcIDListData structure. It is the
5926 hash negotiated in the SKE protocol. Affected file is
5929 * Slight redesigning of the SilcAuthPayload handling routines.
5930 Do not send SilcPKCS but SilcPublicKey as argument.
5932 * Implemented the public key authentication support to the
5933 serverconfig. The public key is loaded from the provided path
5934 and saved as authentication data to void * pointer. Thus,
5935 changed the unsigned char *auth_data to void *auth_data;
5937 * Fixed SHUTDOWN command to send the reply before the server
5938 is shutdown. :) Affected file silcd/command.c.
5940 * Fixed fatal bug in CONNECT command. The hostname was invalid
5941 memory and server crashed. Affected file silcd/command.c.
5943 * Fixed fatal bug in CLOSE command. The server_entry became
5944 invalid but was referenced later in the command. Affected file
5947 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Fixed fatal bug in failure packet handling. Server ignored
5950 the failure and thus crashed when it came.
5954 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5957 that the command may be executed only once in (about) 2 seconds.
5958 The old SILC_CF_LAG flag is same but allows command bursts up
5959 to five before limiting.
5961 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5962 server code. Various commands now includes the CF_LAG_STRICT
5963 flag to disallow any kind of miss-use of the command.
5965 * Fixed the silc_buffer_unformat to not to allocate any data
5966 if the length of the data is zero. It used to allocate the
5967 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5969 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Changed the format of AdminConnection configuration section
5972 in the server. Added username of the admin to the format.
5973 Affected files silcd/serverconfig.[ch].
5975 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5976 to return admin configuration data by host, username and/or
5979 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Implemented WHOWAS command to the server. Added the functions:
5983 silc_server_command_whowas_parse,
5984 silc_server_command_whowas_send_reply,
5985 silc_server_command_whowas_from_client and
5986 silc_server_command_whowas_from_server
5988 * Added <Client ID> argument to the WHOWAS command reply. Updated
5989 the protocol specs accordingly.
5991 * Implemented WHOWAS command and command_reply to the client
5994 Implemented the WHOWAS printing on the user interface.
5996 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5998 * Added new argument to the WHOWAS command reply, the real name.
5999 It is an optional argument. Updated the protocol specs.
6001 * Added SilcIDCacheDestructor callback that is registered when
6002 the SilcIDCache is allocated. The callback is called when
6003 an cache entry in the ID Cache expires, or is purged from the
6004 cache. Added into lib/silccore/idcache.[ch].
6006 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6007 to destruct the client entries when the cache entry expires.
6008 Other ID Cache's in server and in the client library ignores
6011 * If the ID Cache entry's `expire' field is zero then the entry
6012 never expires. Added boolean `expire' argument to the
6013 silc_idcache_add function in the lib/silccore/idcache.[ch].
6014 If it is TRUE the default expiry value is used.
6016 * Added silc_server_free_client_data_timeout that is registered
6017 when client disconnects. By default for 5 minutes we preserve
6018 the client entry for history - for WHOWAS command.
6020 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6022 * Added support to the server to enforce that commands are not
6023 executed more than once in 2 seconds. If server receives
6024 commands from client more frequently, timeout is registered
6025 to process the commands. Affected file silcd/command.c.
6026 Added new function silc_server_command_process_timeout.
6028 * Changed NICK_NOTIFY handling in client library to check that
6029 if the client's nickname was changed, so there is no need to
6030 resolve anything from the server.
6032 * Removed error printing from the WHOIS and IDENTIFY commands.
6033 If error occurs then it is ignored silently in the client library.
6034 The application, however, may map the received error to
6035 human readable error string. The application currently maps
6036 the NO_SUCH_NICKNAME error to string.
6038 * Made the command status message public to the application. Moved
6039 them from lib/silcclient/command_reply.c to
6040 lib/silcclient/command_reply.h. The application can map the
6041 received command status to the string with the
6042 silc_client_command_status_message function.
6044 * Added check to the server to check that client's ID is same
6045 as the Source ID in the packet the client sent. They must
6048 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6050 * Added dist-bzip hook to the Makefile.am to make bzip2
6051 compressed distributions.
6053 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Server now enforces the maximum length for the nickname and
6056 the channel as protocol specification dictates. 128 bytes for
6057 nickname and 256 bytes for channel name.
6059 * Moved the WHOIS printing to the application. The client libary
6060 does not print out the WHOIS information anymore, the application
6061 must do it. Renamed silc_client_command_reply_whois_print to
6062 the silc_client_command_reply_whois_save.
6064 The client's idle time is also sent to the application now, and
6065 the idle is shown on screen.
6067 * Added silc_client_command_reply_identify_save to save the
6068 received IDENTIFY entries.
6070 * Do not check for channel private keys in message sending and
6071 reception if the channel does not have the PRIVKEY mode set.
6072 Affected file lib/silclient/client_channel.c.
6074 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6077 just surfaced after chaning the JOIN procedure.
6079 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6081 * Added silc_client_get_clients_by_list to get client entries
6082 from Client ID list, that is returned for example by JOIN
6083 and USERS command replies. The application should use this
6084 function for example when JOIN command reply is received to
6085 resolve the clients already on the channel (library does not
6086 do that anymore as USERS command reply is not used in the JOIN
6087 procedure anymore). Affected files lib/silcclient/silcapi.h and
6088 lib/silcclient/idlist.c.
6090 * JOIN command reply and USERS command reply returns now SilcBuffer
6091 pointers instead of unsigned char pointers when returning
6092 the client list and mode list.
6094 * Added <Client ID> argument to the JOIN command reply, mainly
6095 for the server to identify for which client the command was
6096 originally sent. Updated protocol specs accordingly.
6098 * Added SilcDlist private_key pointer to the SilcChannelEntry
6099 in the client to support the channel private keys. Affected
6100 file is lib/silcclient/idlist.h.
6102 * Added SilcChannelPrivateKey argument to the function
6103 silc_client_send_channel_message so that application can choose
6104 to use specific private ke if it wants to. If it is not provided,
6105 the normal channel key is used, unless private keys are set.
6106 In this case the first (key that was added first) is used
6107 as the encryption key.
6109 * Implemented the support for channel private key handling.
6110 Implemented the following functions:
6112 silc_client_add_channel_private_key,
6113 silc_client_del_channel_private_keys,
6114 silc_client_del_channel_private_key,
6115 silc_client_list_channel_private_keys and
6116 silc_client_free_channel_private_keys
6118 Affected file lib/silcclient/client_channel.c.
6120 * Added the support for the private keys in the channel message
6121 sending and encryption and in the message reception and
6122 decryption. Affected funtions are
6123 silc_client_send_channel_message and silc_client_channel_message.
6125 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Added SKE's key verify callback to the client library's
6128 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6130 * Removed the statement that server (or router) must send USERS
6131 command reply when joining to the channel so that the client
6132 knows who are on the channel. Instead, the client list and
6133 client's mode list is now sent in the JOIN command reply to the
6134 client who joined channel. This is better solution.
6136 * Added function silc_server_get_users_on_channel and function
6137 silc_server_save_users_on_channel to the silcd/server.[ch].
6139 * Removed function silc_server_command_send_users from the
6142 * Do not show topic on the client library anymore. The topic is
6143 sent in the command reply notify to the application and the
6144 application must show the topic now.
6146 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6148 * Added client searching by nickname hash into the IDENTIFY and
6149 WHOIS commands in the server as they were clearly missing from
6150 them. Affected file is silcd/command.c.
6152 * Fixed a bug in private message receiving in the client library.
6153 The remote ID was freed and it wasn't supposed, now it is
6156 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Minor fix to the channel payload; allocate the data area, as it
6159 needs to be of specific length.
6161 * If the key agreement port is zero then the operating
6162 system will define the bound port. Affected files are
6163 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6165 * Added new function silc_channel_payload_decrypt into the file
6166 lib/silccore/silcchannel.[ch].
6168 * Moved the channel message etc, check from silc_packet_decrypt
6169 to applications. The library calls now a generic
6170 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6171 when the packet is either normal or special. This was done to
6172 allow more wide range of checking that was not allowed when
6173 the code was in library. Now applications can do virtually any
6174 checks to the packet and return to the library the decision how
6175 the packet should be processed. Affected files are
6176 lib/silccore/silcpacket.[ch].
6178 Added silc_server_packet_decrypt_check to the server and
6179 silc_client_packet_decrypt_check to the client library.
6181 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6182 to send with specified source and destination information.
6184 * Channel message delivery between routers was broken after the
6185 channel key distribution was fixed earlier. The channel key
6186 was used be to distributed to other routers as well which is not
6187 allowed by the protocol. Now this is fixed and channel keys
6188 really are cell specific and the channel message delivery between
6189 routers comply with the protocol specification.
6191 * Fixed various commands in server to check also the global list
6192 for the channel entry and not just the local list. The affected
6193 file silcd/command.c.
6195 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6197 * Added assert()s to buffer formatting and unformatting routines
6198 to assert (if --enable-debug) when error occurs. Affected
6199 file: lib/silcutil/silcbuffmt.c.
6201 * Changed to auto-reconnect to check whether the remote host is
6202 router and register the re-connect timeout if it is. It used
6203 to check that whether we are normal server, but router must do
6204 auto-reconnect with another router as well. Affected file
6207 * Removed the [<key len>] option from CMODE command as the cipher
6208 name decides the key length, nowadays. See the defined ciphers
6209 from the protocol specification.
6211 * Added [<hmac>] option to the CMODE command to define the HMAC
6212 for the channel. Added SILC_CMODE_HMAC channel mode.
6214 * Added [<hmac>] option for the JOIN command so that user can
6215 select which HMAC is used to compute the MACs of the channel
6218 * Added Hmac field to the Channel Message Payload. The integrity
6219 of plaintext channel messages are now protected by computing
6220 MAC of the message and attaching the MAC to the payload. The
6221 MAC is encrypted. Now, it is clear that this causes some
6222 overhead to the size of the packet but rationale for this is that
6223 now the receiver can verify whether the channel message decrypted
6224 correctly and also when private keys are set for the channel the
6225 receiver can decrypt the packet with several keys and check from
6226 the MAC which key decrypted the message correctly.
6228 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6229 lib/silccrypt/silccipher.[ch].
6231 * Added silc_hash_len to return the digest length into the
6232 lib/silcrypt/silchash.[ch].
6234 * Rewrote parts of Silc Channel Payload interface in the
6235 lib/silccore/silcchannel.[ch]. The encode function now also
6236 encrypts the packet and parse function decrypts it.
6238 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Fixed a minor formatting bug in the SKE's key material processing.
6241 It actually might have processed the keys wrong way resulting
6244 * Redefined the mandatory HMAC algorithms and added new algorithms.
6245 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6246 and hmac-md5 truncated to 96 bits. The mandatory is now
6247 hmac-sha1-96. Rest are optional (including the one that used
6248 to be mandatory). Rationale for this is that the truncated HMAC
6249 length is sufficient from security point of view and can actually
6250 make the attack against the HMAC harder. Also, the truncated
6251 HMAC causes less overhead to the packets. See the RFC2104 for
6254 * Added new [hmac] configuration section. The SKE used to use
6255 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6256 is of course wrong. The official names that must be proposed in
6257 the SKE are the ones defined in the protocol specification
6258 (hmac-sha1-96 for example). The user can configure any hmac
6259 using any hash function configured in the [hash] section. At
6260 least, the mandatory must be configured.
6262 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6264 * Added HMAC list to the SKE proposal list. It has now both
6265 hash algorithm list and HMAC list. This makes the protocol
6266 incompatible with previous versions. The SKE now seems to work
6267 the way it is supposed to work, for the first time actually.
6269 * Defined plain Hash algorithms to the protocol specification.
6272 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Implemented support for key agreement packets into the server.
6275 Added functions silc_server_key_agreement and
6276 silc_server_send_key_agreement. Other than these functions,
6277 server has nothing to do with this packet.
6279 * Added support for private message key packets into the server.
6280 Added functions silc_server_private_message_key and
6281 silc_server_send_private_message_key.
6285 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6286 called in the protocol's final callback instead in the END
6287 protocol state. This makes a little more sense and in the same
6288 time in client we can use the same protocol routines for normal
6289 key exchange and to key agreement packet handling as well.
6291 * Added to both client's and server's KE protocol context the
6292 SilcSKEKeyMaterial pointer to save the key material. We will
6293 bring the key material to the protocol's final callback by doing
6294 this. The final callback must free the key material.
6296 * Added SKE's packet_send callback into client's KE protocol
6297 context so that the caller can choose what packet sending function
6298 is used. This way we can use different packet sending when
6299 doing normal SKE when doing key agreement packet handling (in
6300 the key agreement packet handling we do not want to encrypt
6303 * Implemented the responder side of the key agreement routines
6304 in the client. The client can now bind to specified port and
6305 accept incoming key negotiation. The key material is passed
6306 to the application after the protocol is over.
6308 * Implemented the processing of incoming Key Agreement packet
6309 in the client. Added function silc_client_key_agreement to
6312 * Implemented the intiator side of the key agreement routines
6313 in the client. The client can now initiate key agreement with
6314 another remote client. The key material is passed to the
6315 application after the protocol is over.
6317 * Created client_keyagr.c to include all the key agreement
6320 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6321 SILC_TASK_CALLBACK except that it is not static.
6323 * Created client_notify.c and moved the Notify packet handling
6324 from the client.[ch] into that file.
6326 * Created client_prvmsg.c and moved all private message and
6327 private message key routines from the client.[ch] into that file.
6329 * Create client_channel.c and moved all channel message and
6330 channel private key routines from the client.[ch] into that file.
6332 * Changed silc_client_get_client_by_id_resolve to resolve with
6333 WHOIS command instead of IDENTIFY command, in the file
6334 lib/silclient/idlist.c.
6336 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Implemented the SKE's responder side to the Client library.
6340 * When FAILURE is received to the protocol do not trust it
6341 blindly. Register a timeout to wait whether the remote closes
6342 the connection as it should do it, only after that process the
6343 actual failure. This was changed to both client and server.
6345 * Added client_internal.h to include some of the structures
6346 there instead of client.h in lib/silcclient/.
6348 * Added function silc_task_unregister_by_callback to unregister
6349 timeouts by the callback function.
6351 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Some "Incomplete WHOIS info" errors has been appearing on the
6354 log files. Took away the entry->userinfo check from WHOIS
6355 reply sending. The entry->userinfo is now " " if client did not
6356 provide one. I thought this was fixed earlier but something
6357 is wrong still. Let's see if the error still appears.
6359 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6361 * Fixed a minor bug in the login when the channel key is
6362 re-generated in the server. It used to generate the key in
6363 wrong order and thus caused problems in the channel traffic.
6365 * Fixed a minor bug in channel key distsribution after
6366 KICK command. The key was not sent to the router even though
6369 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Added silc_ske_process_key_material_data as generic routine
6372 to process any key material as the SILC protocol dictates. The
6373 function is used by the actual SKE library but can be used by
6374 applications as well. This relates to the private message keys
6375 and the channel private keys since they must be processed the
6376 same way the normal SILC session keys. The protocol dictates
6377 this. Affected files: lib/silcske/silcske.[ch].
6379 Added also silc_ske_free_key_material to free the
6380 SilcSKEKeyMaterial structure.
6382 * Defined silc_cipher_set_key function to set the key for
6383 cipher without using the object's method function. The affected
6384 files: lib/silccrypt/silccipher.[ch].
6386 * Implemented silc silc_client_add_private_message_key,
6387 silc_client_add_private_message_key_ske,
6388 silc_client_del_private_message_key,
6389 silc_client_list_private_message_keys and
6390 silc_client_free_private_message_keys functions in the
6393 Added functions silc_client_send_private_message_key to send
6394 the Private Message Key payload and silc_client_private_message_key
6395 to handle incoming Private Message Key payload.
6397 * Added Cipher field to the Private Message Key payload to set
6398 the cipher to be used. If ignored, the default cipher defined
6399 in the SILC protocol (aes-256-cbc) is used.
6401 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Removed lib/silcclient/ops.h file.
6405 Redefined parts of the SILC Client Library API. Created new
6406 file silcapi.h that deprecates the ops.h file and defines the
6407 published Client Library API. Defined also private message key
6408 API and channel private key API into the file.
6410 This is the file that the application must include from the
6411 SILC Client Library. Other files need not be included by
6412 the application anymore.
6414 * Added new key_agreement client operation callback and also
6415 defined the Key Agreement library API for the application.
6417 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6420 is used by clients to request key negotiation between another
6421 client in the SILC network. If the negotiation is started it
6422 is performed using the SKE protocol. The result of the
6423 negotiation, the secret key material, can be used for example
6424 as private message key.
6426 Implemented the Key Agreement payload into the files
6427 lib/silccore/silauth.[ch].
6429 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6431 * Redefined ciphers for the SILC protocol. Added some new ciphers
6432 and defined the key lengths for the algorithms. Changed the
6433 code accordingly. The default key length is now 256 bits.
6435 * Fixed SKE key distribution function silc_ske_process_key_material
6436 when the key length is more than 128 bits. The default key
6437 length in SILC is now 256 bits.
6439 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6440 to indicate unsupported algorithm.
6442 * Renamed rijndael.c to aes.c and all functions as well.
6444 * Fixed a long standing channel key setting bug in client library.
6445 Weird that it has never surfaced before.
6447 * Fixed bug in channel deletion. If the entire channel is removed
6448 then it must also delete the references of the channel entry
6449 from the client's channel list as the client's channel entry and
6450 the channel's client entry share same memory.
6452 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Implemented CONNECT and SHUTDOWN commands in the client.
6456 * Implemented CLOSE command to the client.
6458 * Added the function silc_idlist_find_server_by_name into the
6459 files silcd/idlist.[ch].
6461 Added the function silc_idlist_find_server_by_conn into the
6462 files silcd/idlist.[ch].
6464 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * DIE command was renamed to SHUTDOWN. Updated the both code
6469 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6470 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6472 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6475 * Added function silc_server_create_connection function to create
6476 connection to remote router. My server implementation actually
6477 does not allow router to connect to normal server (it expects
6478 that normal server always initiates the connection to the router)
6479 so the CONNECT command is only good for connecting to another
6482 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6485 or some other client was kicked from the channel.
6487 Implemented the handling of the notify type to both client
6490 Implemented silc_server_send_notify_kicked to send the KICKED
6491 notify. It is used to send it to the server's primary router.
6493 * Implemented the KICK command into server and client.
6495 * Added `query' argument to the silc_idlist_get_client function
6496 to indicate whether to query the client from server or not if
6499 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6500 to indicate that the client is not channel founder.
6504 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Removed the rng context from SilcPacketContext structure and
6507 changed that the packet routine uses the Global RNG API.
6509 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6511 * Added support for quit message that client can "leave" on the
6512 channel when it quits the SILC. It is ditributed inside the
6513 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6515 Added silc_server_free_client_data that will take the
6516 signoff message as argument.
6518 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6520 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Updated parts of the protocol specification to keep it up
6525 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6528 payloads in one packet.
6530 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6531 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6532 use now the new List flag.
6534 * Also deprecated the following packet types: REPLACE_ID,
6535 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6537 * Added list support for Notify packet in server.
6539 * Added silc_server_send_notify_channel_change to send the
6540 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6541 the silc_server_send_replace_id.
6543 * Added silc_server_send_notify_nick_change to send the
6544 NICK_CHANGE notify type. Deprecates the function
6545 silc_server_send_replace_id.
6547 * Added silc_server_send_notify_join to send the JOIN notify type.
6548 Deprecates the function silc_server_send_new_channel_user.
6550 * Added silc_server_send_notify_leave to send LEAVE notify type.
6551 Deprecates the function silc_server_send_remove_channel_user.
6553 * Added silc_server_send_notify_cmode and
6554 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6555 types. Deprecates the silc_server_send_set_mode function.
6557 * Added SERVER_SIGNOFF notify type to indicate that server has
6558 quit. This means that all clients on the channel from that
6559 server will drop. This can be also used when netsplit happens.
6561 Deprecated REMOVE_ID packet type since it is not needed anymore
6564 Added silc_server_send_notify_server_signoff to send the
6565 SERVER_SIGNOFF notify type. Deprecates the function
6566 silc_server_send_remove_id.
6568 Added also silc_server_send_notify_signoff to send the
6569 SIGNOFF notify type.
6571 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6572 SILC protocol from this day on. Changed the protocol
6573 specification as well.
6575 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6576 notify type. It is used between routers to notify about
6577 topic changes on a channel.
6579 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6582 * Partly updated the protocol specification to comply with the
6583 changes now made. It is still though a bit outdated.
6585 * The JOIN notify type now takes one extra argument <Channel ID>.
6586 The packet used to be destined to the channel but now the
6587 JOIN type may be sent as list thus it is impossible to
6588 destine it to any specific channel. By adding this argument
6589 it is again possible.
6591 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Added CREDITS file. The CHANGES and CREDITS file will appear
6594 in the distribution as well.
6596 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6599 types in the server's silcd/packet_receive.c.
6601 * Implemented CMODE and CUMODE to work in router environment.
6603 * Fixed minor encoding and decoding buglet from the
6604 lib/silccore/silcmode.c.
6606 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6609 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6611 * Changed all SilcConfigServer* and silc_config_server* to
6612 SilcServerConfig* and silc_server_config*, respectively.
6615 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Associated the ID (client or server ID) to the Authentication
6618 Payload to avoid any possibility of forging. Updated the
6619 protocol specification and the code accordingly.
6621 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6623 * The RSA key length is now save to the RsaKey context in the
6624 key generation process in lib/silccrypt/rsa.c. The key length
6625 is now used to figure out the maximum size of the block allowed
6626 to be encrypted/signed.
6628 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6629 is equivalent to the silc_mp_mp2bin but does not allocate any
6632 * Changed silc_mp_mp2bin API to take length argument. If it is
6633 non-zero then the buffer is allocated that large. If zero, then
6634 the size is approximated using silc_mp_sizeinbase, which however
6637 * Created Global RNG API which is global RNG that application can
6638 initialize. After initializing, any routine anywhere in the
6639 code (including library) can use RNG without allocating a new
6640 RNG object. This was done to allow this sort of use of the
6641 RNG in code that has no chance to allocate RNG object. All
6642 applications currently allocate this and many routines in the
6643 library use this. Affected file lib/silccrypt/silcrng.[ch].
6645 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6646 it to use the Global RNG API.
6648 * Defined Authentication Payload into protocol specification that
6649 is used during SILC session to authenticate entities. It is
6650 used for example by client to authenticate itself to the server
6651 to obtain server operator privileges.
6653 Implemented this payload into the lib/silccore/silcauth.[ch].
6654 Implemented also routines for public key based authentication
6655 as the new protocol specification dictates.
6657 Moved definitions of different authentication methods from
6658 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6660 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6661 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6662 silc_pkcs_verify_with_hash functions into the file
6663 lib/silccrypt/silcpkcs.[ch].
6665 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * The client entry's userinfo pointer must be always valid.
6668 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6669 will fail since it requires the userinfo. Now, the userinfo
6670 is allocated as "" if actual userinfo does not exist. Actually,
6671 it must exist and it is totally Ok to drop client connections
6672 that does not announce the userinfo. However, we will make
6673 this workaround for now.
6675 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6676 to return the remote port by socket.
6678 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6681 SILC_SERVER_PENDING_EXEC and added an new macro
6682 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6683 data or when error occurs while processing the pending command.
6685 Added new argument `destructor' into silc_server_command_pending
6686 and to the SilcServerCommandPending object. This destructor is
6687 now called after calling the pending callback or if error occurs
6688 immediately. If error occurs the actual pending callback won't
6689 be called at all - only the destructor. The destructor may be
6690 NULL if destructor is not needed.
6692 All this applies for client library code as well. Similar
6693 changes were made there as well for the pending commands.
6695 In the client, the application must now allocate the
6696 SilcClientCommandContext with the silc_client_command_alloc
6699 * Added reference counter to the SilcServerCommandContext. Added
6700 function silc_server_command_alloc and silc_server_command_dup
6703 Same type of functions added to the client library for the same
6706 * Removed the cmd_ident from IDListData away since it is now
6707 global for all connections. It is the command identifier used
6708 in command sending and with pending commands. The affected file
6711 * Added reference counter to the SilcSocketConnection objecet to
6712 indicate the usage count of the object. The object won't be
6713 freed untill the reference counter hits zero. Currently only
6714 server uses this, and client ignores it. The client must be
6715 set to use this too later. The affected files are
6716 lib/silccore/silcsockconn.[ch]. Added also the function
6717 silc_socket_dup to increase the reference counter.
6719 This was mainly added because it is possible that the socket
6720 is removed underneath of pending command or other async
6721 operation. Now it won't be free'd and proper DISCONNECTING
6722 flags, etc. can be set to avoid sending data to connection that
6723 is not valid anymore.
6725 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6726 the connection. After that it sets SILC_SET_DISCONNECTED.
6727 It is, however, possible that the socket data is not still freed.
6728 The silc_server_packet_process now checks that data is not
6729 read or written to connection that is DISCONNECTED. The socket
6730 get's freed when the reference counter hits zero.
6732 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * Changed the client operation API: channel_message operation's
6735 `sender' is now the client entry of the sender, not the nickname
6736 and the `channel' is the channel entry, not the channel name.
6738 In the private_message operation the `sender' is now also the
6739 client entry of the sender not the nickname.
6741 Affected file is lib/silcclient/ops.h and all applications
6742 using the client operations.
6744 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6746 * Moved the calling of ops->connect() from connect_to_server_final
6747 into receive_new_id functin since that is the point when the
6748 client is actually allowed to send traffic to network. The
6749 affected file is lib/silcclient/client.c.
6751 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6754 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6755 (if needs broadcasting) instead of broadcasting the packets one
6756 by one which would make a burst in the network traffic.
6758 * Added `broadcast' argument to the functions in silcd/server.[ch]
6759 silc_server_create_new_channel[_with_id] to indicate whether
6760 to send New Channel packet to primary router.
6762 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Added new function into the silcd/server.[ch] files:
6765 silc_server_create_new_channel_with_id to create new channel with
6766 already existing Channel ID.
6768 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6769 lib/silccore/silcpacket.h. This packet is used t send list of
6770 Set Mode payloads inside one packet. Server uses this to set
6771 the modes for the channels and clients on those channels, that it
6772 announced to the router when it connected to it. The protocol
6773 specification has been updated accordingly.
6775 * The silc_server_new_channel did not handle the packet coming
6776 from normal server as it normally does not send that. However,
6777 when it announces its channels it does send it. Implemented
6778 the support for that.
6780 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6781 into the file lib/silccore/id.h.
6783 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Fixed memory leaks in the functions silc_idlist_del_client,
6786 silc_idlist_del_channel and silc_idlist_del_server in the file
6787 silcd/idlist.c. All of those leaked like a sieve.
6789 * Fixed some small memory leaks in the client's function
6790 silc_client_notify_by_server.
6792 * Added functions into silcd/server.c: silc_server_announce_clients,
6793 silc_server_announce_channels and silc_server_announce_server.
6794 These functions are used by normal and router server to announce
6795 to its primary router about clients, channels and servers (when
6796 router) that we own. This is done after we've connected to the
6799 These functions effectively implements the following packet types:
6800 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6801 and SILC_PACKET_NEW_ID_LIST.
6803 * Added new functions into the silcd/packet_receive.[ch]:
6804 silc_server_new_id_list, silc_server_new_channel_list and
6805 silc_server_new_channel_user_list to handle the incoming
6806 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6808 * Added support of changing Channel ID in the function
6809 silc_server_replace_id. If the server that announces a channel
6810 to the router already exists in the router (with same name but
6811 with different Channel ID), router is responsible to send
6812 Replace ID packet to the server and force the server to change
6813 the Channel ID to the one router has.
6815 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6816 client that the Channel ID has been changed by the router. The
6817 normal server sends this to the client. Client must start using
6818 the new Channel ID as the channel's ID.
6820 Implemented handling of this new type into lib/silcclient/client.c
6821 into the function silc_client_notify_by_server.
6823 * Added new function silc_idlist_replace_channel_id into the files
6824 silcd/idlist.[ch] to replace the Channel ID.
6826 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6828 * Call silc_server_command_identify_check always when processing
6829 the IDENTIFY command in silcd/command.c
6831 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6834 send keepalive packets. The packet can be sent by clients,
6835 servers and routers.
6837 Added function silc_socket_set_heartbeat into the file
6838 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6839 If not set, the heartbeat is not performed. The actual
6840 heartbeat is implemented in the low level socket connection
6841 library. However, application is responsible of actually
6844 Added silc_server_send_heartbeat to send the actual heartbeat
6845 packet into silcd/packet_send.[ch]. Server now performs
6846 keepalive with all connections.
6848 * Added silc_task_get_first function into lib/silcutil/silctask.c
6849 to return the timeout task with shortest timeout. There was a bug
6850 in task unregistration that caused problems. TODO has been
6851 updated to include that task system must be rewritten.
6853 * The client library will now resolve the client information when
6854 receiving JOIN notify from server for client that we know but
6855 have incomplete information.
6857 * Rewrote parts of silc_server_remove_from_channels and
6858 silc_server_remove_from_one_channel as they did not remove the
6859 channel in some circumstances even though they should've.
6861 * Encryption problem encountered in server:
6863 The LEAVE command used to send the Channel Key packet to the
6864 router immediately after generating it. However, the code
6865 had earlier sent Remove Channel user packet but not immediately,
6866 ie. it was put to queue. The order of packets in the router
6867 was that Channel Key packet was first and Remove Channel User
6868 packet was second, even though they were encrypted in the
6869 reverse order. For this reason, MAC check failed. Now, this
6870 is fixed by not sending the Channel Key packet immediately but
6871 putting it to queue. However, this is more fundamental problem:
6872 packets that are in queue should actually not be encrypted
6873 because packets that are sent immediately gets encrypted
6874 actually with wrong IV (and thus MAC check fails). So, packets
6875 that are in queue should be encrypted when they are sent to
6876 the wire and not when they put to the queue.
6878 However, the problem is that the current system has not been
6879 designed to work that way. Instead, the packet is encrypted
6880 as soon as possible and left to the queue. The queue is then
6881 just purged into wire. There won't be any fixes for this
6882 any time soon. So, the current semantic for packet sending
6885 o If you send packet to remote host and do not force the send
6886 (the packet will be in queue) then all subsequent packets to the
6887 same remote host must also be put to the queue. Only after the
6888 queue has been purged is it safe again to force the packet
6891 o If you send all packets immediately then it safe to send
6892 any of subsequent packets through the queue, however, after
6893 the first packet is put to queue then any subsequent packets
6894 must also be put to the queue.
6896 Follow these rules and everything works fine.
6898 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Added new function silc_server_remove_clients_by_server to
6901 remove all client entries from ID list when the server connection
6902 is lost. In this case it is also important to invalidate all
6903 client entires as they hold the invalid server entry. This
6904 fixes fatal bug when server has lost connection and will reconnect
6907 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Made some sanity checks to silc_server_daemonise like to check
6910 whether the requested user and group actually exists.
6912 * Added sanity check to SKE's silc_ske_responder_finish to check
6913 that the public and private key actually is valid.
6915 * Invalidate the client's nickname when receiving Replace ID
6916 packet and the Client ID is being replaced. This means that the
6917 server will query the nickname if someone needs it (client)
6920 * Sort the ID Cache in client library when the ID Cache data
6921 has changed (needs sorting).
6923 * Do not allow for SILC client to create several connections to
6924 several servers. The client does not support windows right now
6925 and generating multiple connections causes weird behaviour.
6927 Irssi-silc client does support windows and can handle several
6928 connections without problems, see: www.irssi.org and SILC plugin.
6930 * Fixed some places where client was added to the IDList. The
6931 rule of thumb is following (in order to get everything right):
6932 If the client is directly connected local client then the
6933 `connection' argument must be set and `router' argument must be
6934 NULL to silc_idlist_add_client function. If the client is not
6935 directly connected client then the `router' argument must
6936 bet set and the `connection' argument must be NULL to the
6937 silc_idlist_add_client function.
6939 * The funtion silc_server_packet_send_local_channel actually did
6940 not check whether the client was locally connected or not. It
6941 does that now. Fixed a bug related to LEAVE command.
6943 * Fixed Remove Channel User payload parsing bug in server's
6944 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6946 * The server's silc_server_save_channel_key now checks also the
6947 global ID list for the channel as it might not be in the local
6948 list. Fixed a bug related to LEAVE command.
6950 * Is this the end of the [<unknown>] buglet that has been lurking
6951 around for a long time? A little for loop fix in server's
6952 silc_server_command_whois_parse that is used by both IDENTIFY
6953 and WHOIS command. At least, this was a clear bug and a cause
6954 of one type of [<unknown>] buglet.
6956 * WHOIS and IDENTIFY commands call the function
6957 silc_server_command_[whois/identify]_check function even if
6958 we are not router server.
6960 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * Added --with-gmp configuration option. If set the GMP
6963 is always compiled in the SILC source tree. If not set then
6964 it is checked whether the system has the GMP3 installed. If
6965 it has then the GMP won't be compiled (the system's headers
6966 and library is used), if it doesn't have it then the GMP is
6967 compiled in the SILC source tree.
6969 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Changed RSA private exponent generation to what PKCS #1
6972 suggests. We try to find the smallest possible d by doing
6973 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6974 not security fix but optimization.
6976 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6978 * Added new config entry [Identity] to fork the server and run
6979 it as specific user and group. A patch from Bostik.
6981 * Imported Dotconf configuration library into lib/dotconf.
6982 This will be used to create the SILC configuration files later.
6983 It will appear in the distsribution after this commit.
6985 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6987 * A big code auditing weekend happening. Auditing code for
6988 obvious mistakes, bugs and errors. Also, removing any code
6991 Removed files for being obsolete:
6993 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6994 inline in the file lib/silcutil/silcbuffer.h)
6996 o lib/silcutil/silcbufutil.c (the header has inline versions)
6998 Changed code to fix possible error conditions:
7000 o The buffer formatting routines now check that the destination
7001 buffer really has enough space to add the data. This applies for
7002 both buffer formatting and unformatting
7003 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7004 unformatting was changed to accomodate following rules:
7005 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7006 sent to the function while XXX_*STRING will not allocate or copy
7007 the data into the buffer. Instead it sets the pointer from the
7008 buffer into the pointer sent as argument (XXX_*STRING used to
7009 require that the pointer must be allocated already). This change
7010 makes this whole thing a bit more consistent and more optimized
7011 (note that the data returned in the unformatting with XXX_*STRING
7012 must not be freed now). The routines return now -1 on error.
7014 o Tried to find all code that use buffer_format and buffer_unformat
7015 and added return value checking to prevent formatting and
7016 especially unformatting errors and possible subsequent fatal
7019 o Changed ske->x and ske->KEY to mallocated pointers in
7020 lib/silcske/silcske.h. Fixed possible data and memory leak.
7022 o Added return value checking to all *_parse* functions. Fixed
7023 many memory leaks as well.
7025 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7026 so that buffer overflows would not happen. All code now also
7027 checks the return value as it can fail.
7029 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7031 * Added reconnection support to server if the normal server looses
7032 its connection to the router (for example if router is rebooted).
7033 The server performs normal reconnection strategy implemented
7034 to the server. Affected file silcd/server.c.
7036 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7038 * Added new packet type SILC_PACKET_SET_MODE that is used to
7039 distribute the information about changed modes (for clients,
7040 channels and clients channel modes) to all routers in the
7041 network. Updated the protocol specification accordingly.
7043 Added functions into silcd/packet_send.c and
7044 silcd/packet_receive.c: silc_server_send_set_mode,
7045 silc_server_set_mode.
7047 Added new files silcmode.[ch] into lib/silccore that implements
7048 the encoding and decoding of Set Mode Payload. Added new type
7049 SilcSetModePayload. Moved the definitions of different modes
7050 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7052 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7054 * Oops, a little mistake in server's connection authentication
7055 protocol. The protocol is not ended with FAILURE but with
7056 SUCCESS if the authentication is Ok. :) Affected file is
7059 * Implemented NICK_CHANGE notify handling in server in the file
7060 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7061 the local clients on the channel. After the changing nickname
7062 in router environment snhould work and the [<unknown>] nickname
7063 should appear no more.
7065 The silc_server_replace_id function that receives the Replace ID
7066 payload now sends the NICK_CHANGE notify type also in the file
7067 silcd/packet_receive.c
7069 * Changed WHOIS and IDENTIFY command to support the maximum amount
7070 of arguments defined in protocol specs (3328 arguments). This
7071 fixed a bug that caused problems when there were more than three
7074 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7076 * Added extra parameter, command identifier, to the
7077 silc_client_send_command so that explicit command identifier
7080 Changed that ID list routines uses specific command identifier
7081 when sending WHOIS/IDENTIFY requests to the server so that they
7082 can be identified when the reply comes back.
7084 Affected files lib/silcclient/command.[ch],
7085 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7087 * Added `sender' argument to silc_server_packet_send_to_channel
7088 to indicaet the sender who originally sent the packet to us
7089 that we are now re-sending. Ignored if NULL. Affected file
7090 silcd/packet_send.[ch].
7092 * Added some server statistics support in silcd/server_internal.h
7093 SilcServerStatistics structure and around the server code. Also
7094 send some nice statistics information when client is connecting
7097 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Fixed channel ID decoding in server's JOIN command reply in
7100 silcd/command_reply.c
7102 * Fixed braodcasting of replace ID payload to not to send it if
7103 we are standalone server in silcd/packet_receive.c.
7105 * Fixed all channel message sending routines to not to send
7106 packets to clients that has router set, since they are routed
7107 separately in the same function earlier. Affects file
7108 silcd/packet_send.c and all channel packet sending functions.
7110 * In USERS reply, res_argv[i] are not allocated, the table
7111 is allocated. Thus changed that free the table, not its
7114 * In server's whois_check and identify_check if the client is
7115 locally connected do not send any WHOIS commands - they are not
7118 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Fixed some minor bugs in client when sending WHOIS command. The
7121 arguments was in wrong order.
7123 * Removed statis function add_to_channel from server in
7124 silcd/command.c that was previously used with the joining but
7127 * Tested USERS command in router environment successfully with two
7128 routers, two servers and two clients.
7130 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Reorganized the USERS command and command reply in client library
7133 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7134 When the command is given by user we register a pending command
7135 callback that will reprocess the command after the reply has been
7136 received from the server. When reprocessing the packet we then
7137 display the information. Thus, the USERS information is displayed
7138 now in the command callback instead of in the command reply
7139 callback. The processing of the command is same as previously
7140 when server has sent the command reply in the JOINing process.
7142 * Added to USERS command in silcd/command_reply.c to join the client,
7143 we didn't use to know about, to the channel after we've created
7144 a client entry for it. Also, for clienet we did know already still
7145 check whether it is on the channel or not and add it if not.
7147 * Removed silc_server_command_join_notify as the function and its
7150 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7152 * Changed the client's pending command handling to the same as the
7153 server's pending command handling. It is also now possible to
7154 execute command reply functions from other command reply
7155 function as the function callbacks for commands and command
7156 replies are one and same. The pending commands are not static
7157 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7158 in client connection context. Thus, pending commands are server
7159 connection specific as it is convenient.
7161 Changed the function silc_client_command_pending and
7162 silc_client_command_pending_del and added new function
7163 silc_client_command_pending_check. Removed the
7164 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7167 * Added cmd_ident, current command identifier, to the client
7168 connection context in lib/silcclient/client.h to keep track on
7169 command identifiers used in command sending. Client's command reply
7170 function handling now supports the mandatory command identifiers.
7172 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7173 funtions in client to fully support pending command callbacks.
7175 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7176 as one of the arguments to the application in the command reply
7179 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7180 before first releasing SILC but came back. Now it is removed again
7181 and should come back nomore. The FORWARDED flag was used only
7182 by the JOINing procedure by forwarding the command packet to router.
7183 Now, the JOINing procedure has been changed to more generic (due
7184 to various router environment issues) and FORWARDED is not needed
7185 anymore for anything. The protocol specification is yet to be
7188 Now, removed silc_server_packet_forward from server and the flag
7189 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7191 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7193 * Renamed NAMES command to USERS command. The NAMES was named that
7194 due to historical reasons. Now it is renamed. Also, rewrote
7195 parts of the USERS command. The nickname list is not sent anymore
7196 by the server. Only Client ID and mode lists are sent in the USERS
7197 command. Changed this also to the protocol specification.
7199 The client now resolves the names and stuff after it receives
7200 the USERS list from the server when joining to the channel.
7202 * WHOIS and IDENTIFY commands has been changed to support multiple
7203 Client ID's per command. One can now search for multiple users
7204 in the network by sending only one WHOIS or IDENTIFY command.
7205 Changed the code and the protocol specifications.
7207 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7208 uses silc_server_command_whois_parse to parse the request. */
7210 * If normal server, do not parse the WHOIS and IDENTIFY requests
7211 before sending it to the router. Saves some time.
7213 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7215 * Fixed JOIN command on client library. Wrong number of arguments
7216 used to crash the client.
7218 * Added silc_server_channel_has_global function to check whether
7219 channel has global users or not.
7221 * Added silc_server_channel_has_local function to check whether channel
7222 has locally connected clients on the channel.
7224 * The silc_server_remove_from_one_channel now checks whether the
7225 channel has global users or not after given client was removed from
7226 the channel. It also checks whether the channel has local clients
7227 on the channel anymore. If it does not have then the channel entry
7228 is removed as it is not needed anymore.
7230 * The silc_server_notify now checks on JOIN notify whether the joining
7231 client is one of locally connected or global. If it is global then
7232 the channel has now global users on the channel and that is marked
7233 to the channel entry. Also, it now saves the global client to
7234 global list who is joining and JOINs it to the channel. This is
7235 for normal server, that is.
7237 Changed silc_server_send_notify_on_channel,
7238 silc_server_packet_relay_to_channel and
7239 silc_server_packet_send_to_channel check if we are normal server
7240 and client has router set (ie. global client) do not send the
7241 message to that client, as it is already routed to our router.
7243 * Implemented LEAVE notify type handling in silc_server_notify
7246 * Tested LEAVE command in router environment successfully. Tested
7247 with two routers, two servers and two clients.
7251 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7253 * Implemented SIGNOFF notify type handling in silc_server_notify
7256 * silc_server_remove_id now removes the client entry from all channels
7257 it has joined and thusly sends SIGNOFF notify type.
7259 * Rewrote the NAMES list generation in server by removing two excess
7260 loops. The lists are created now inside one loop.
7262 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7264 * silc_server_remove_channel_user checks now also global list
7265 for channel and client.
7267 * silc_server_new_channel_user checks now both local and global
7268 list for channel and client. Fixed a bug in client id decoding.
7269 Used to decode wrong buffer.
7271 * silc_server_channel_message checks now both local and global
7272 list for channel entry.
7274 * Tested channel joining (hence JOIN) in router environment
7275 successfully. Tested with two routers, two servers and two
7278 * Tested channel message sending in router environment successfully.
7280 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Added silc_server_save_channel_key into server.[ch] to save the
7283 received channel key in Channel Key payload processing. It is
7284 also used in JOIN command reply handling.
7286 Equivalent function silc_client_save_channel_key added into
7287 client.[ch] into client library.
7289 * Changed JOIN command reply to send information whether the channel
7290 was created or not (is existing already) and the channel key
7291 payload. Changed protocol specs accordingly.
7293 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7294 the request was sent by ID and not by nickname. Crashed on
7297 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7299 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7300 now correctly save the received data.
7302 * silc_server_free_sock_user_data now notifies routers in the
7303 network about entities leaving the network.
7305 At the same time implemented functions silc_server_remove_id
7306 and silc_server_send_remove_id to receive and send REMOVE_ID
7307 packets. The packet is used to notify routers in the network
7308 about leaving entities. The ID removed will become invalid in
7311 * Added function silc_idlist_del_server into server. Removes and
7312 free's server entry from ID list.
7314 * silc_server_private_message function now checks, if we are router,
7315 that the destination ID really is valid ID, naturally.
7317 * In router when NEW_ID packet is received (for new client) the
7318 hash of the Client ID is saved in the ID Cache but the
7319 client->nickname is set to NULL, instead of putting the hash
7322 IDENTIFY command now also checks that client->nickname must be
7323 valid. If it is not if will request the data from the server who
7324 owns the client. Added new function
7325 silc_server_command_identify_check.
7327 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7328 to set the command to already allocated Command Payload.
7330 * Tested private message sending in router environment with two
7331 routers, two servers and two clients. Fixed minor bugs and now
7334 * Fixed segfault from client's NAMES command. Used to crash if
7337 * Forwarded packets must not be routed even if it is not destined
7338 to the receiver. Changed server code comply with this.
7340 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7342 * Added `require_reverse_mapping' boolean value to ServerParams
7343 structure. If TRUE (not default) the server will require that
7344 the connecting host has fully qualified domain name.
7346 If the reverse mapping is not required and hostname could not be
7347 found the IP address is used as hostname.
7349 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Implemented version string checking to both client and server.
7352 The check is incomplete currently due to the abnormal version
7353 strings used in development version of SILC.
7355 * Changed all command functions in server to use the new
7358 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7360 * Changed char *data to unsigned char *data in ID Cache system to
7361 support binary data as ID Cache data. Changed code to support
7362 binary data in lib/silccore/idcache.c.
7364 * Renamed silc_server_packet_relay_command_reply to
7365 silc_server_command_reply as it is normal packet receiving
7366 function. Rewrote the function to accept command replys for
7367 servers and not only for clients.
7369 * Mark remote router always as registered server if we are connecting
7370 to it. Otherwise, commands sent by the router to us are ignored.
7372 * All ID List find routines now returns the ID Cache Entry pointer
7373 as well if requested.
7375 * WHOIS command works now in router environment, tested with two
7376 routers, two servers and two clients.
7378 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7379 in router environment (as it is almost equivalent to WHOIS) but
7380 hasn't been tested thoroughly. Added new functions:
7382 silc_server_command_identify_parse
7383 silc_server_command_identify_send_reply
7384 silc_server_command_identify_from_client
7385 silc_server_command_identify_from_server
7387 * Disabled route cache adding because adding two different ID's with
7388 same IP replaces the old cache entry thus giving wrong route.
7389 The entry->router->connection is always the fastest route anyway
7390 so route cache may not be needed. Of course, new routes maybe
7391 established after receiving the ID when the entry->router->connection
7392 might not be anymore the most optimal.
7394 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * Add route cache for received ID for fast routing.
7398 * Added silc_server_packet_route to route received packet on router
7399 that is not destined to us.
7401 * Renamed silc_server_get_route to silc_server_route_get.
7403 * Added id_string and id_string_len fields into SilcServer to
7404 include encoded ServerID for fast comparing without excess
7405 encoding of the ID's.
7407 * Cleaned up WHOIS command on server side. Added following static
7410 silc_server_command_whois_parse
7411 silc_server_command_whois_check
7412 silc_server_command_whois_send_reply
7413 silc_server_command_whois_from_client
7414 silc_server_command_whois_from_server
7416 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7417 arguments in command replies. All command functions should be
7418 updated to use this macro.
7420 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Minor typo fixes on command reply handling on server.
7424 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7426 * Added silc_server_command_add_to_channel internal routine to add
7427 the client to the channel after router has created the channel and
7428 sent command reply to the server.
7430 * Added generic silc_server_send_command to send any command from
7433 * Use static buffer with ID rendering instead of duplicating data.
7435 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7437 * Fixed a channel user mode bug when joining to a channel server gave
7438 everybody channel founder rights, oops.
7440 * We mark ourselves as the router of the incoming server connection
7441 if we are router ourselves. This way we can check in some packet
7442 sending functions whether it is locally connected server. For
7443 incoming router connections we put NULL.
7445 * For router sending packets locally means now always sending the
7446 packet cell wide; to local clients and local servers. For normal
7447 server sending packet locally means sending it to only local
7450 * Fixed the JOIN command to really work in router environment. If the
7451 channel is created it is always created by the router. Router is
7452 also responsible of making the initial joining to the channel,
7453 sending JOIN notify to the sending server and distributing
7454 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7455 does not exist server doesn't do anything else but forward the
7456 command to the router which performs everything.
7458 * Added silc_server_send_channel_key function to send the Channel Key
7461 * Added silc_server_create_channel_key to create new channel key. The
7462 channel key is now re-generated everytime someone joins or leaves
7463 a channel, as protocol dictates. Note: channel->key_len is the
7466 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7469 packet_receive.[ch] to separate packet sending and receiving
7470 routines. The server.[ch] now includes everything else including
7471 actual packet processing (writing and reading data) and other
7474 Renamed silc_server_private_message_send_internal to
7475 silc_server_send_private_message. The routine is still though
7476 used only to relay private messages as server does not send
7477 private messages itself.
7479 Renamed silc_server_new_channel to silc_server_create_new_channel
7480 and added new function sicl_server_new_channel that handles the
7481 incoming New Channel packet. Added also new sending function
7482 silc_server_send_new_channel to send New Channel Payload.
7484 * Added new function silc_server_notify to process incoming notify
7485 packet to the server/router. Server may then relay the notify
7486 to clients if needed.
7488 * Added new function silc_server_new_channel_user to process incoming
7489 New Channel User packet. Router will redistribute the packet and
7490 send JOIN notify to its local clients and locally connected servers
7491 if needed. Normal server will send JOIN notify to its local client
7492 on same channel when received this packet. Added also corresponding
7493 sending function silc_server_send_new_channel_user to sent the
7496 * Added boolean route argument to send_notif_to_channel and
7497 packet_send_to_channel functions to attempt to route the packet
7498 if it is TRUE and send only locally if it is FALSE.
7500 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7502 * silc_server_replace_id now broadcasts the received replace ID
7503 packet if it is not broadcast packet already. The router must
7504 broadcast to inform other routers about changed ID.
7506 * Added backpointer to server's router into SilcServer context in
7507 silcd/server_internal.h.
7509 * Fixed silc_server_packet_broadcast to send correct broadcast
7512 * The channel key is now distributed to the local client as soon
7513 as it is received from the router (in router environment) so that
7514 no other packet may be sent for the channel until client has
7517 * silc_server_remove_channel_user now broadcasts the received
7518 Remove Channel User packet if it is not broadcast packet already.
7519 The router must broadcast to inform other routers about removed
7522 * Added users field into SilcPacketContext that is a reference count
7523 of the context. One can increase the reference count by calling
7524 silc_packet_context_dup which is now changed to just increase the
7525 reference count instead of duplicating the data. The reference
7526 count is decresed by calling silc_packet_context_free that will
7527 free the data after the reference count hits zero.
7529 For now on the packet context and everything allocated into it
7530 (including the raw packet from network) must be freed by calling
7531 the new silc_packet_context_free function. Added also new function
7532 silc_packet_context_alloc that must be used now to allocate the
7533 context. This also means that if a routine is asynchronous from
7534 silc_[client/server]_packet_parse_type the packet context must
7535 be duplicated by calling silc_packet_context_dup. Otherwise it
7536 gets free'd after silc_[client/server]_packet_parse_type returns.
7537 Also, one must remember that if packet is duplicated then its
7538 reference count must be decresed by calling the free function as
7539 many times as it was duplicated.
7541 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7542 from both client and server.
7544 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7546 * Made joining to a channel working in router environment.
7548 * Cleaned up JOIN command on server side and create function
7549 silc_server_command_join_channel internal routine to make the
7552 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * Changed silc_command_pending list to SilcDList. Also, added
7555 `ident' field to SilcServerCommandPending structure to identify
7556 the reply and to call correct callback.
7558 Added silc_server_command_pending_check function to replace the
7559 corresnponding macro. The silc_command_pending list is not
7562 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7563 to set identifier to previously allocated Command Payload. It
7564 is used to set identifier for command when resending Command
7567 * Added silc_command_payload_encode_payload to encode Command
7568 Payload buffer from SilcCommandPayload structure.
7570 * Added silc_argument_payload_encode_payload to encode Argument
7571 payload buffer from SilcArgumentPayload structure.
7573 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * Changed WHOIS command to support router connection on server side.
7576 The whois request is always sent to router unless the server is
7577 standalone server. After server has received the reply from the
7578 router will it send the reply to the client.
7580 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7581 broadcast received broadcast packet. The function is used only
7582 by router. The broadcast packet is always sent to the router's
7585 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7586 render given ID to printable string, for log files for example.
7588 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7590 * Made basic router to router connections working. At least they
7591 can now connect to each other but nothing really works the way
7592 they are supposed - yet.
7594 * Added new initiator token to RouterConnection configuration
7595 file in silcd/serverconfig.[ch]. It is used to tell whether we
7596 are the initiator to the remote router or whether we'll expect
7597 the other end to connect.
7599 * Moved registering of listener task to silc_server_init, hence
7600 the server starts listenning as soon as it is run, even if it
7601 does not have connections to other routers. Let's see how well
7604 * Changed default connection retry timeouts for more suitable in
7607 * Removed cipher and such arguments from silc_idlist_add_client
7608 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7609 Added new function silc_idlist_add_data to add the keys and stuff
7612 * Added SilcIDListData structure and added it to SilcClientEntry
7613 and SilcServerEntry as their first field in the structure. This
7614 way we can explicitly cast the ID entries to the SilcIDListData
7615 structure and get common data for the entries. In past, we had
7616 to first check what type of connection it is and then cast it to
7617 correct ID entry type. Now, we can directly cast the opaque
7618 pointer to the SilcIDListData (no matter what ID entry it actually
7619 is) and get the data needed.
7621 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7624 in some circumstances even if threre were timeout tasks, though not
7625 IO tasks, but tasks anyway. Now fixed.
7627 * Defined SilcServerConnection structure to hold connection specific
7628 stuff about directly connected servers and routers. The definition
7629 is currently in silcd/server_internal.h. I thought about having
7630 a bit more important role fro this struct but for now it is used
7631 only when connecting to other server (or router actually).
7633 * Added connecting retry support in server when connecting to
7634 router(s). The retry feature implement exponential backoff
7635 algorithm. Also, added SilcServerParams structure to hold default
7636 parameters for server. For now, it include these retry settings
7637 and are hard coded. After server is moded to be as Silc Server
7638 Library this structure will be more important.
7640 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Changed client librarys channel->clients table to SilcList and
7643 changed code accordingly.
7645 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7647 * Changed client's channel table to SilcList and changed code
7648 accordingly. Also changed SilcChannelClientEntry to include back-
7649 pointer to the channel so that client entry can use that structure
7650 as list as well and we have fast cross-reference to the channel.
7651 This change dramatically decreased the complexity of channel
7652 handling with client entry and vice versa (removed one extra
7653 loop when searching for channel entry from many functions).
7655 * Changed server->sim from table to SilcDList and changed code
7658 * NAMES command can now be used from user interface. It will show
7659 the user list on the channel, neatly.
7661 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7662 Code now saves realname of the user if it becomes available.
7664 * Renamed configure.in to configure.in.pre and made ./prepare
7665 script to automatically add correct version string to
7666 configure.in which it creates from configure.in.pre.
7668 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7670 * NAMES command reply now shows users mode with the nickname when
7673 * Moved silc_client_ch[u]mode[_char] functions from
7674 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7675 place sucks, they are utility functions and should be in some
7678 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7680 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7683 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Added TRQ (efficient deque and list library) into lib/trq. This is
7688 a very good list library that is currently used in the SILC. Defined
7689 SilcList API over the library because I didn't like the API very
7690 much. See lib/trq/silclist.h for the API and examples of how to
7691 use the API. Fixed various places in the code to use the new
7692 SilcList API. The SilcList is meant for lists that has a structure
7693 already defined as a list. It is not suitable to add just some
7694 context to the list (in TRQ, the context is the list actually).
7696 So, I defined SilcDList that can be used for the purpose where
7697 predefined list structure does not exit. This can be used as
7698 such list. Now some context just can be added to the SilcDList.
7699 Currently this list is not used in the SILC just yet, though there
7700 are a lot places where this can replace dynamically allocated
7701 tables and I will fix these places, later, to use SilcDList.
7702 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7703 and use TRQ internally).
7705 Also fixed some annoying warning messages that the original TRQ
7706 code generated. Also minor changes to TRQ's Makefile.in.
7708 * Added support for querying by Client ID to both WHOIS and
7709 IDENTIFY commands into server, as required by the protocol.
7711 * Removed method function pointers from SilcBuffer structure. They
7712 weren't used to anything and just increased the context size for
7713 no good reason. This change also made silc_buffer_alloc and
7714 silc_buffer_free functions inline functions.
7716 * Disabled command flooding detection support until it's fixed so
7717 that it accepts commands in but does not execute them more than once
7720 * Added silc_net_localhost(), to return local hostname, into
7721 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7722 that must be initialized before calling silc_client_init.
7724 * Added new function: silc_server_send_notify_on_channels to send
7725 notify messages to all channels client has joined. It is assured
7726 that the message is sent only once per client.
7728 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7729 lib/silcutil/silcutil.[ch] as silc_format function. The new
7730 function is generic and is used by server as well, not only by
7731 the logging routines.
7733 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7734 the provided version string was not acceptable. Added new function:
7735 silc_ske_check_version into lib/silcske/silcske.h. The function
7736 must be implemented by the application (client or server) and it
7737 does not reside in the SKE library. The function checks the version
7738 string remote end sent.
7740 * Added back pointers (to opaque context and to SilcSocketConnection)
7741 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7743 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7744 duplicate packet context structure.
7746 * Changed `notify' client operation to send same arguments as client
7747 receives from server except for ID's. ID's are mapped to correct
7748 ID entry and that is returned. Also, if channel entry is not sent
7749 by server but the notify is for channel the channel entry is sent
7750 to application (otherwise application doesn't know that it is for
7751 channel (library gets it from packet's Destination ID)).
7753 * Added silc_client_remove_from_channels into client library to
7754 remove a client from all channels it has joined to. Used when
7755 received SIGNOFF notify from server. Added also new function
7756 silc_client_replace_from_channels to replace old ID entry with
7757 new ID entry on all channels. Used when received NICK_CHANGE
7760 * Fixed ID Cache list handling in silc_idlist_get_client in
7761 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7762 to get (or query) client by ID.
7764 * Updated TODO list.
7766 * Added connection authentication status message defined by the
7767 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7768 support for these into the code in client and server side.
7770 * Added generic function silc_client_send_command to send any command
7771 with variable argument list. Application should use this function
7772 to send commands if the command functions provided by the library
7773 does not suite for the application's user interface needs.
7775 * Added new `failure' client operation. Application is notified about
7776 received failure packet if client is executing a protocol. In this
7777 case the protocol's execution has failed.
7779 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7780 is required by the protocol.
7782 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7783 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7786 * Added status flag to SilcSKE object to indicate realtime status
7787 of the SKE protocol.
7789 * Application receives now exactly same command reply arguments as
7790 the library receives from server. However, if ID is received the
7791 corresponding ID entry is returned to the application (eg. Client
7792 ID is mapped to correct SilcClientEntry entry and that is returned).
7793 Changed command_reply client operation due to this change.
7795 * Changed all ID's in commands and in command replys as ID Payloads.
7796 Change affected both client and server side codes.
7798 All ID's sent in SILC network (with execption of ID's in SILC
7799 Packet header) are sent in ID Payload to support variable length
7802 * Server now notifies nick changes and notifies all clients on
7803 the channels about the new nickname (about the new Client ID,
7806 * Implemented CMODE command to change channel modes. Supports all
7807 channel modes defined by the protocol specs except ban and invite
7808 lists. (Also, private channel key mode is supported but support for
7809 setting private channel key in client is missing, thus, this mode
7810 has no effect on client side (except that server requires that the
7811 client uses private channel key and normal channel traffic does not
7814 Also, invite mode works per se, but INVITE command does not work
7815 yet correctly, so you can set channel as invite only channel but
7816 inviting clients to the channel does not work (it is yet to be
7817 thought what's the best way to do it).
7819 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7820 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7821 Implemented CUMODE command to change user's mode on the channel.
7822 Supports all modes defined by the protocol specs.
7824 * Added NAMES command reply to return users modes on the channel.
7826 * Removed unnecessary and slow ciphers from lib/silccrypt.
7828 * Set SO_KEEPALIVE option to connection sockets by default.
7830 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7832 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7833 redefined the Notify Payload into protocol specs.
7835 * Added silc_id_payload_parse_id to get ID directly from raw
7838 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7841 accept searching by Client ID as well.
7843 * Added support for LEAVE and SIGNOFF notify types in client library.
7845 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7846 to parse ID Payload from raw data.
7848 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7850 * Added flags parameter into silc_ske_assemble_security_properties
7851 function in lib/silcske/silcske.[ch].
7853 * Changed notify client operation to fit better for notify messages
7854 sent by server. The notify payload received from server is now
7855 passed to the application (after parsing it to SilcNotifyPayload).
7856 It is application's responsibility to retrieve the arguments
7857 from the payload and show the message the way it wants. The message
7858 sent by server is implementation specific.
7860 * Changed public keys to comply with the protocol specification.
7861 Old public keys are not supported anymore and are not compatible.
7863 * Removed nickname from Channel Payload as the latest draft removed
7864 it. The client must resolve the nickname from the NAMES command
7865 reply received when it joined the channel.
7867 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7869 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7871 * Fixed some errors in protocol specification drafts.
7873 * Created lib/silccore/silcnotify.c to implement Notify Payload
7874 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7875 generic payloads described by protocol specifications. The file
7876 includes implementations for ID Payload and Argument Payload.
7878 * Changed Command Payload implementation to use the new Argument
7879 Payload. Changed command_xxxx_payload to command_payload_xxxx
7880 to comply with SILC coding conventions.
7882 * Added suppport for Argument Payload handling in Notify Payload
7883 implementation as protocol requires it. Added the new support
7884 into server and client lib as well.
7886 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7888 * Added support for multiple nicknames on same channel. [n] is
7889 added locally to the nickname if there are more than one same
7890 nicknames on the channel.
7892 * Server now sends all nicknames that matched WHOIS request.
7893 Client also shows the list received from server.
7895 * Added TOPIC command to client side. User can now set and show
7896 current topic on channel.
7898 * Added MOTD command to client and server. Also, server sends the
7899 motd when client connects to the server.
7901 * Changed version strings to comply ISO 8601.
7903 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7905 * Fixed protocol error handling in client library. It should now
7906 cope even if the SKE fails for some reason.
7908 * Made new protocol specification drafts for submitting to IETF.
7910 * Implemented TOPIC command to server in silcd/command.c.
7912 * Added two new notify types into lib/silccore/silcnotify.h:
7913 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7914 notify nickname change and topic setting/change on a channel.
7916 * API change of command_reply operation in client library. The
7917 application gets now the status type received from server as well.
7919 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7921 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7923 * Cras fixed and optimized the packet handling even further and
7924 it should work now. Minor change to the prototype of function
7925 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7927 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Added new function into lib/silcutil/silcschedule.[ch]:
7930 silc_schedule_with_fd to select() a specified fd. The function
7931 returns after timeout expires or data arrives or goes. The
7932 function is used by packet routines to wait that all data is
7933 received from network.
7935 * Fixed data reading from network in lib/silccore/silcpacket.c.
7936 The code now assures that all data is read from the fd and then
7937 continues packet processing. This was a bug fix since the code
7938 used to drop some data in some circumstances.
7940 * Added new function into lib/silcclient/client.[ch]:
7941 silc_client_start_key_exchange to start key exchange after
7942 connection has been established to server. The code internally
7943 now uses this funtion but its main purpose was to provide it
7944 for applications that perform their own connecting. After
7945 application has created a connection it merely calls this
7946 function to start the key exchange between client and server.
7947 The library takes care of everything else after that.
7949 Updated also lib/silcclient/README to explain the usage of
7952 * Do not send to application information that connection has
7953 been established. Application gets notified it by connect
7956 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7958 * Applied cras's patch to add silc_schedule_one function. The
7959 function runs scheduler once and returns.
7961 * Fixed the scheduler after cras messed it up. The timeout
7962 handling works now as it's supposed to work.
7964 * Added into lib/silccore/ silcnotify.h to include notify
7965 message types support. Changed silc_server_send_notify*
7966 functions, in server.[ch], to support those new notify types.
7967 Added the support for the notify types into client library,
7968 as well. Added new notify client operation into ops.h in
7971 * Changed silc_server_packet_send_to_channel to send normal
7972 packets instead of just channel message packets. The function
7973 is now used to send the notify packets to channels. It is not
7974 used to send channel message packets anymore, as server never
7977 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7978 va_arg()s as it seems to require it nowadays. I guess, if SILC
7979 is compiled with older va_arg() the new code should work anyway.
7981 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7983 * Splitted core library. Core library (lib/silccore) includes
7984 now only SILC protocol specific core (and common) components.
7985 Created new utility library (lib/silcutil) that includes more
7986 generic purpose stuff. The stuff for util library was taken
7987 from the old core library. This was minor and easy split.
7989 * Created SILC Client Library (lib/silcclient) that includes
7990 implementation of the SILC client without user interface. This
7991 was major move from silc/ directory. The code has been changed
7992 so that it is transparent towards the user interface. The
7993 silc/ directory includes now the same user interface as before
7994 and it uses the new client library. Read lib/silcclient/README.
7995 Basicly, the client library performs everything else related
7996 to SILC except user interface handling. Also, configuration
7997 files are considered to be part of user interface and library
7998 does not handle them.
8000 This change also changed a lot of structures, function naming etc.
8001 Most important change was that SilcClientWindow object was
8002 renamed to SilcClientConnection in the client library. Created
8003 also new file lib/silcclient/ops.h. Also added new files
8004 silc/local_command.[ch] and silc/client_ops.[ch].
8006 All these changes were made to make it easier for user interface
8007 designers to create what ever user interface for the SILC client
8010 It is also expected that the server will be moved to lib
8011 directory as well and SILC Server Library will be created;
8012 sometimes in the future.
8014 * Removed Local commands from lib/silccore/silccommand.h as
8015 they are application specific and new client library does not
8016 handle any of those anymore.
8018 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8019 old client implementation in silc/.
8021 * Added support for callback functions in SILC_LOG_* macros.
8022 Application can now set its own callbacks that will be called
8023 instead of using the default functions that will always print
8024 the debug messages to stderr (or stdout). Also, debugging can
8025 now be disabled by setting silc_debug to FALSE and re-enabled by
8026 setting it to TRUE. Note, that logging will still work even
8027 if debugging is disabled.
8029 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8030 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8031 silc_log_reset_debug_callbacks.
8033 * To enable debugging in silc client one must give now -d
8034 option on command line.
8036 * Changed silc_schedule_init to automatically allocate task queues
8037 if they are not allocated before calling it.
8039 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8041 * Added GMP 3.1 into math library.
8043 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8045 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8046 a channel in SILC network. The packet is used by servers and
8047 routers to notify other routers that user has left a channel.
8048 This little feature was missing until now. Added the feature
8049 to protocol specification as well.
8051 Added functions: silc_server_send_remove_channel_user and
8052 silc_server_remove_channel_user into server.[ch].
8054 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8055 lib/silccore/silcpacket.h. However, they are not implemented
8058 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Fixed joining to a channel and sending channel messages
8061 between server and router. The channel message sending should
8062 now work inside a cell.
8064 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8066 * Fixed the private message sending between server and router.
8067 The private message sending should now work inside a cell.
8069 * Added silc_server_replace_id into server.[ch] to replace
8070 existing ID in the SILC network.
8072 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8073 and silc_idlist_replace_server_id into idlist.[ch] in server.
8075 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8077 * Fixed the server to server connections. Server can again now
8078 connect to router. Router to router connections probably does
8081 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8083 * Added dynamic protocol registering support. Now protocols can
8084 registered and unregistered on the fly. Patch by cras.
8086 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8088 * Added lib/contrib directory to hold routines that some platforms
8089 don't have but are needed by SILC.
8091 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8092 into lin/contrib to provide getopt() and getopt_long() for
8093 those who don't have it.
8095 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8097 * Added AWAY command to client. When away message is set and
8098 client receives a private message packet the client automatically
8099 replies to the sender with the away message.
8101 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8102 bug seemed to be the cause of recent problems when compiling
8105 * Added version detection support to SKE protocol specification
8106 and added the new changes to the SKE implementation as well.
8107 There were other minor changes in the SKE protocol as well.
8109 Many changes in lib/silcske/silcske.[ch] and in
8110 lib/silcske/payload.[ch].
8112 * Added ^U functionality, clear input line. Patch from cras.
8114 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * Mainly small bugfixes on core library. Fixed some debugging
8117 logging and buffer overflow in silclog.c.
8119 * Updated config.sub and config.guess on the distribution tree.
8121 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * Added command lagging support in server. Client may execute
8124 commands now only once in two seconds.
8126 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8128 * Optimized packet reception. MAC computation and checking is now
8129 also more optimized. A lot previously duplicated code is now
8130 used as generic by both client and server.
8132 * Fixed key pair generation in clientutil.c
8134 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8136 * Added into lib/silccore/silcbufutil.[ch] new function;
8137 silc_buffer_realloc.
8139 * Moved generic packet sending/encryption functions to
8140 lib/silccore/silcpacket.[ch] from client and server. Some
8141 rewriting of the functions.
8143 * Moved all generic packet reception/decryption functions to
8144 lib/silccore/silcpacket.[ch] from client and server. The
8145 packet processing is now much cleaner in both client and server.
8146 These were major changes in both client and server.
8148 * Created many common functions in server to do packet sending.
8149 Previously code were duplicated a lot, this has been removed
8152 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8154 * Rewrote major parts of the ID cache system. Don't know
8155 whether it is better now or not but at least the API is more
8158 * Major rewrite on ID cache stuff on client because of the ID
8159 cache API changes. Added idlist.c to client.
8161 * Also major rewrite on ID cache stuff on server as well.
8162 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8163 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8164 in hand, instead they are all put into the ID cache system now.
8165 All server_idlist_* routines uses ID cache now instead of
8166 traversing its own lists (those lists does not exist anymore).
8167 SilcIDList though still exists. Also, SilcXXXEntry's are
8170 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Finally made the SKE implementation compliant to the protocol
8173 specification. All mp integers are now binary encoded as
8174 opposed being HEX encoded.
8176 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8179 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8180 functions: silc_[encode/decode]_pem. Also added function
8181 silc_encode_pem_file to PEM encode with newlines ('\n') for
8184 * SILC public keys are now encoded either PEM or binary. Same
8185 option is for private keys as well. By default private keys
8186 are binary encoded and public keys PEM encoded. Silly HEX
8187 encoding were removed.
8189 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8190 function to create fingerprints.
8192 * Fixed a bug in SHA1; does not change the original data anymore.
8194 * Partly implemented INFO command on client and server side.
8195 Fixed CLEAR command. Changes to SERVER command; show current
8196 server(s) when giving command without arguments. Added
8197 VERSION command to client.
8199 * Added check to server that unregistered connections cannot
8200 execute commands (unless it is specificly allowed).
8202 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Fixed screen refresh.
8206 * Fixed channel joining bug from client. On some circumstances
8207 client tried to join to a channel it had already joined.
8209 * Added public key verification process into client's protocol.c.
8210 The client now verifies the public key from user and saves
8211 it into ~./silc/serverkeys/ directory.
8213 Added into: clientutil.[ch]: silc_client_verify_server_key.
8215 * Changed SKE protocol's silc_ske_initiator_finish function
8216 to accept callback function that verifies the received public
8217 key. Removed old silc_ske_verify_public_key function.
8219 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8221 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8222 silc_pkcs_private_key[_data]_set.
8224 * Made the password and public authentication more cleaner in
8225 server's protocol.c.
8227 * Removed historic and obsolete protocol `channel_auth' from
8228 both client and server.
8230 * Removed wrong way of sending command status messages from
8231 server to client in server's command.c. The old way violated
8232 protocol specification.
8234 Changes to silccore/silccommand.[ch]: removed
8235 silc_command_encode_status_payload -> not needed anymore,
8236 changed silc_command_encode_payload_va to accept extra
8237 argument on variable argument list. The argument type must
8238 now be provided to the function. Also, added new function:
8239 silc_command_encode_reply_payload_va which is same as
8240 normal command_encode_payload_va except command status type
8241 is provided as extra argument.
8243 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8245 * Added ~./silc directory handling. The directory includes the
8246 public and private keys for the client.
8248 Added silc_client_check_silc_dir, silc_client_create_identifier
8249 and silc_client_load_keys.
8251 * Implemented SILC protocol compliant public key. Added public
8252 and private key saving to and loading from files.
8254 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8255 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8256 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8257 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8258 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8260 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8261 silc_pkcs_load_[public/private]_key.
8263 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8265 * Added silc_server_get_route (route.[ch]) to get connection
8266 data for the fastest route for given ID.
8268 * Implemented INVITE command on client and server. The command
8269 were re-defined in the SILC Protocol Specification and the
8270 implementation now complies with the specification.
8272 * Implemented PING command on client and server.
8274 * Implemented NAMES command on client and server. The server side
8275 supports currently only normal server not router server yet.
8276 Some changes to NAMES definition in SILC protocol specification.
8278 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Implemented LEAVE command on client and server.
8282 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8283 again. This change was made to the protocol as well. Server
8284 should not violate the protocol specification anymore.
8286 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8288 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8289 was tested. SOCKS4 was not but should work anyway.
