100 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
101 Updated the protocol specs and the code in server. The
102 affected file is silcd/packet_receive.c.
104 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
106 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
107 that it is used to send error notifys if error occurs during
108 some SILC packet processing, except commands. The error
109 types are same as for command reply types. Defined that
110 if private message is sent to unknown Client ID the error
111 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
112 Updated the protocol specs and code. Affected files are
113 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
114 lib/silcclient/client_notify.c, silcd/packet_receive.c,

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

154 another command may attach to the same pending command reply
155 without requiring to resolve the same entry again. Added
156 support for adding multiple pending commands for one
157 command idenfier. Affected files lib/silcclient/command.[ch],
158 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

175 so that WHOIS always shows joined channels also in normal
176 server and not just on router. Affected file is
177 silcd/command_reply.c.
179 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

205 mask to the client. Updated protocol specs and the server.
206 Affected file is silcd/command.c.
208 * Changed the Killer's Client ID in KILLED notify to be just
209 any ID payload since router server is allowed to kill as well.
210 Updated protocol specs, client libary and server. Affected
211 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
212 and irssi/src/silc/core/client_ops.c.

227 may set to itself to tell server not send channel messages.
228 Other packets such as channel key packets are still sent.
229 Protocol TODO #23. Updated the protocol specs, client and
230 server. Affected files are lib/silccore/silcmode.h,
231 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
232 lib/silcutil/silcutil.c, silcd/command.c, and
235 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Redefined the Status Payload to include now two 8 bit fields,
238 instead of one 16 bit field. This now makes it possible to
239 send list of errors. Updated the protocol specs and the code
240 in core library, client library and server. Protocol TODO #1.
241 Affected files are lib/silccore/silccommand.[ch],
242 lib/silcclient/command_reply.[ch], silcd/command.c,

245 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
247 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
248 must be handled by the application and should tell the application
249 that an error message was already printed, and it should print the
250 config coords (line, filename, ...). Affected files are
251 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].

272 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
274 * Added STATS command to the protocol after all, to return
275 various statistical information about the network. It can
276 be used by clients to retrieve statistical information, and
277 servers may use it to to fetch cell and network wide
278 statistics from router. Updated the protocol specs and
279 implemented it to the server. Protocol TODO #16.
280 Affected files are lib/silccore/silccommand, silcd/command.[ch],
281 silcd/command_reply.[ch].
283 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
285 * The LIST command reply in client libary now adds new channel
286 entry if the returned channel doesn't exist yet in cache,
287 and returns the channel entry to the application in the
288 command_reply client operation. Affected file is
289 lib/silcclient/command_reply.c.
291 * Changed the channel message payload's MAC generation to
292 include the IV in the MAC as well. This way all relevant
293 parts of the channel message payload are authenticated also
294 with the channel message MAC (and not only by packet MAC).
295 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
296 Affected file is lib/silccore/silcchannel.c.
298 * Fixed the SKE to save the remote version, since the
299 silc_ske_parse_version mistakenly checked wrong version,
300 after it replaced the start payload. Affected files are

324 need the SilcSocketConnection which should not be visible
325 to application. Affected files are lib/silcclient/client.c
326 and lib/silcclient/silcclient.h.
328 * Rewrote the text for Private Message Key Payload in the
329 protocol specification. Protocol TODO #11.

345 silcd/packet_receive.c, packet_send.[ch],
346 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
347 The killer's client entry is now returned to application in
348 the `notify' client operation.
350 * Fixed the Max Argument fields that had too large value set
351 in the protocol specs. Protocol TODO #14.
353 * Added the LEAVE command reply to return the ID of parted
354 channel. Updated protocol specs and implemented it to the
355 client and server. Protocol TODO #15. Affected files are
356 silcd/command.c, lib/silcclient/command_reply.c. The channel
357 entry is now returned to application in the `command_reply'

361 and in server to use the silc_parse_version_string. Affected
362 files are lib/silcclient/protocol.c, silcd/protocol.c.
364 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
365 commands that was missing it, and updated protocol specs and
366 the server implementation. Protocol TODO #10. The affected
367 file is silcd/command.c.
369 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
370 generic reply to a generic request (REQUEST flag), and
371 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
372 way. A draft-riikonen-silc-flags-payloads-00.txt is written
373 to define the payload for DATA flag. Added the flags to
374 the implementation. Protocol TODO #9. Affected file is
375 lib/silccore/silcchannel.h.
377 Changed the client library to return the message length

382 and lib/silcclient/client_ops_example.c.
384 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
385 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
386 the channel. Updated protocol specs and impelemented this
387 to client and server. Protocol TODO #6. Affected files are
388 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

391 Added new options m and M to CMODE command in Irssi SILC
392 client to set these modes.
394 * Deprecated all administrative commands from SILC protocol
395 since they are highly implementation specific commands.
396 Updated protocol specs. Moved the old commands in
397 implementations to private range of command types. Affected
398 files are silcd/command.c, lib/silcclient/command.c and
399 lib/silcclient/command_reply.c. Protocol TODO #8.

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

450 * Changed the object argument for silc_cipher_register,
451 silc_hash_register, silc_hmac_register and silc_pkcs_register
452 to const. Affected files are lib/silccrypt/silccipher.[ch],
453 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
455 * Changed the silc_get_username and silc_get_real_name to
456 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
458 * Fixed the Irssi SILC Client to use the silc_get_username and
459 silc_get_real_name insted of glib routines since the glib
460 routines only corrupt stack. Fixes the Irssi SILC to work in
461 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
463 * Fixed the Irssi to not use g_get_home_dir since it crashes
464 or returns garbage on cygwin and corrupts stack. Added function
465 get_home_dir to Irssi routines. Affected files are
466 irssi/src/core/misc.[ch] and irssi/src/core/core.c.

472 SilcPacketContext structure.
474 Affected files lib/silcsftp/sftp_fs_memory.c,
475 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
477 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
479 * And yet again reverted back the config thing since Johnny
480 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
483 * Fixed memory leaks from config object. Affected files are
484 silcd/serverconfig.[ch].
486 * Added support for adding new connections to the server in rehash.
487 After rehash they take effect.
489 Added support for changing the maximum allowed connections in
490 rehash. The number can grow but going smaller is not supported.
492 Added function silc_server_num_sockets_by_remote to the
493 silcd/server_util.[ch].
495 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
497 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
499 * Added preliminary checking during config parsing for a valid
500 public/private key and removed further checks in the code.
501 Affected files are silcd/serverconfig.[ch], server.c.
503 * Moved functions silc_server_drop() and silc_server_daemonise()
504 from server.c to silcd.c since they are stricly related to
505 the application activity.
507 * Reverted a small part of the automatic ref/unref since
508 it caused a double unref in some situations. Affected
509 files are silcd/silcd.[ch], server.c, serverconfig.c.
511 * Added some .cvsignore files in the lib directory.
513 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
515 * Fixed silc_net_gethostbyaddr to correctly resolve by
516 address. Affected file lib/silcutil/silcnet.c.
518 * Fixed the notify relaying to client. The HMAC to be used
519 with relayed packets ws wrong and caused decryption failure
520 at the client end. Affected file is silcd/packet_receive.c.
522 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Created new branch silc_protocol_1_0_branch.
526 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
528 * Changed the silc_server_config_* routines to be SilcServer
529 independent. They are now officially application specific code
530 and not part of generic server implementation. Affected files
531 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
533 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
535 * Added automatic referencing of config context in the
536 silc_server_config_alloc, and automatic unreferencing in the
537 silc_server_config_destroy. Affected files are
538 silcd/serverconfig.[ch], silcd/silcd.c.
540 * Fixed the silc_log_quick handling in the logging routines.
541 It didn't log quickly when it was TRUE. Affected file is
542 lib/silcutil/silclog.c. Also the flush delay was set even
543 if it was 0 in config file. Affected file is
544 silcd/serverconfig.c.
546 * Added support for changing key pair of the server in rehash.
547 Affected file silcd/server.c.
549 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Fixed the TOPIC_SET notify to not cras. It changed the topic
552 too early, before getting the channel entry. Affected file
553 is silcd/packet_receive.c.
555 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
557 * Added functions silc_server_config_[ref/unref], these are used
558 to prevent that the config object is destroyed.
560 No longer directly affect global variables silc_log_quick and
561 silc_log_delay, they are first cached inside the config object
562 and then applied with silc_server_config_setlogfiles().
564 silc_server_config_set_defaults() is now internal to
565 serverconfig.c, there are no reasons to show this internal stuff
568 Affected files are silcd/serverconfig.[ch].
570 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
571 fprintf's to stderr, since some code may be executed again after
572 the server went into the background. Affected files are
575 * Added rehash support. Added function silc_server_rehash() that
576 will perform all the basic tasks of the rehashing procedure.
578 * Added command line option `-x, --hexdump'. This will enable the
579 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
580 The option `--hexdump' implies `--debug'.
582 * Fixed a bad bug in the logging APIs (silcutil library) where
583 the application would crash after calling silc_log_reset_all().
585 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Fixed the KICKED notify handling in client library to
588 correctly remove the channel and all entries from the
589 channel when I was kicked. This bug crashed the client.
591 Fixed yet another but in KICKED notify handling to remove
592 the kicked client correctly from the channel.
594 Affected file is lib/silcclient/client_notify.c.
596 * Fixed a minor bug in looking up correct client entry
597 in KICKED notify in server. Affected file is
598 silcd/packet_receive.c.
600 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
601 sources correctly to distribution. Fixes --with-gmp option.
603 * Removed the manual rehashing from ID Cache, and changed it
604 to use the SILC Hash Table's auto rehash feature. Affected
605 file is lib/silccore/silcidcache.c.
607 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
609 * Fixed a bug in the silc_client_nickname_format function that
610 handles the multiple same nickname formatting. Two clients
611 with same nickname caused problems after the first one left
612 and rejoined. It didn't format the nickname correctly.
613 Affected file is lib/silcclient/idlist.c.
615 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
617 * Don't change the topic if olod topic is same as new one.
618 Affected file is silcd/packet_receive.c.
620 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
622 * Added cross-reference support to the SILC Documentation
623 generator. All types across all HTML files are now cross-
624 referenced. Affected files util/robodoc/generator.c and
625 scripts/silcdoc/silcdoc.
627 * Added file lib/silcutil/silctypes.h to include all the
628 arithmetic type definitions and some macros. Removed
629 includes/bitmove.h and moved macros to silctypes.h.
631 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
635 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
637 * Added `type' argument to silc_id_payload_parse_id function which
638 now returns the type of the ID to the sent pointer. Affected
639 file is lib/silccore/silcid.[ch].
641 * Added check for CMODE_CHANGE notify type that mode change is
642 allowed by the sender. Affected file silcd/packet_receive.c.
644 * Added check for CUMODE_CHANGE notify type that mode change is
645 allowed by the sender. Affected file silcd/packet_receive.c.
646 Added the ID type as CUMODE_CHANGE notify type as argument
647 to the `notify' client operation. Affected files are
648 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
650 * Added function silc_client_add_server to the client library.
651 Added support for resolving also channel and server info when
652 received unknown entity in notify packet. Affected files are
653 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
655 * Added function silc_command_get_status to return the command
656 status from the command reply's argument payload. Affected files
657 are lib/silccore/silccommand.[ch].
659 * Added check for KICKED notify type that the kicking is
660 allowed by the client. Affected file silcd/packet_receive.c.
662 * Created function silc_get_input which can be used to get input
663 (echo on or off) from user on command line. Affected files are
664 lib/silcutil/silcutil.[ch].
666 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * Optimized silc_server_packet_relay_to_channel function.
669 Added new function silc_channel_message_payload_encrypt which
670 can be called directly if channel message payload needs to
671 be encrypted and is already encoded (no need to call _encode
672 function). Packet relaying is now done by router without any
673 extra memory allocations. Affected files are
674 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
677 * Fixed the INVITE notify handling. It took wrong arguments
678 as invite list and invite delete. Affected file is
679 silcd/packet_receive.c.
681 * Added check for TOPIC_SET notify type that the topic change is
682 allowed by the client. Affected file silcd/packet_receive.c.
684 * Added check for INVITE notify type that inviting is allowed by
685 the client. Affected file silcd/packet_receive.c.
687 * Changed the silc_server_client_on_channel to return the
688 SilcChannelClientEntry as well. Moved the function
689 silc_server_check_cmode_rights to server_util.[ch].
690 Affected files are silcd/server_util.[ch], silcd/command.c.
692 * Added function silc_server_check_umode_rights to check whether
693 changing client's user mode is allowed. Added check for
694 UMODE_CHANGE notify type that the umode change is allowed
695 by the client. Affected files are silcd/server_util.[ch],
696 silcd/packet_receive.c and silcd/command.c.
698 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
701 ID length. It ignored that ID can be IPv6 based as well.
702 Affected file lib/silccore/silcpacket.h.
704 * Fixed the silc_id_id2str and silc_id_str2id to take the
705 IPv6 address offset's into consideration. Affecte file is
706 lib/silccore/silcid.c.
708 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
710 * Fixed the internal Unix scheduler functions to check for
711 NULL context they may receive. The affected file is
712 lib/silcutil/unix/silcunixschedule.c.
714 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
716 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
717 can specify different directory with --home command line
718 parameter. Affected files irssi/src/silc/core/client_ops.c,
721 * SILC-specific commands aren't now executed if the active server
722 isn't of SILC-type, so there won't be problems with having
723 IRC and SILC protocol support in same client. Affected files
724 irssi/src/silc/core/silc-channels.c, silc-servers.c,
727 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Improved the signal support in SILC Schedule. Added new
730 function silc_schedule_signal_call which is used by application
731 to mark a signal to be called. It is now safe to perform
732 any kind of tasks in signal callbacks since it is guaranteed
733 that the application specified signal callback is called
734 after the signal is over. Affected files are
735 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
737 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Added `name' field to SilcChannelPrivateKey to represent
740 application given name for the key. Moved also the context from
741 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
742 Added the `name' argument also to the function
743 silc_client_add_channel_private_key.
745 Added function silc_client_current_channel_private_key to set the
746 current channel private key in use.
748 Added "change" command to KEY command which can be used to change
749 the current channel private key. Bound the command also to
752 Also affected files lib/silcclient/client_channel.c,
753 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
755 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
757 * Added silc_rng_get_byte_fast function in to the
758 lib/silccrypt/silcrng.[ch].
760 * Changed the interface of silc_packet_assemble and the
761 silc_packet_send_prepare. If silc_packet_assmble is now
762 called the application does not call silc_packet_send_prepare
763 because the library will call it automatically. These
764 interfaces now also return a reference to the outgoing buffer
765 which includes the assembled packet, which the application can
766 use to encrypt the packet.
768 Affected files are lib/silccore/silcpacket.[ch],
769 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
770 silcd/packet_send.c, server_backup.c and packet_receive.c.
772 * Fixed a packet sending bug on very high load, where outgoing
773 packet queue wasn't handled correctly and packets got corrupted.
774 Affected files are lib/silcutil/*/silc*sockconn.c,
775 lib/silcclient/client.c and silcd/server.c.
777 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
779 * Added macro SILC_PACKET_DATALEN which can be used during
780 packet assembling to check whether the data to be added to
781 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
782 len is truncated until it fits it.
784 Added checks for maximum length of channel message payload and
785 private message payload also.
787 Added checks for maximum packet length in server and in
790 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
791 lib/silcclient/client.c, lib/silccore/silcchannel.c and
792 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
793 lib/silcclient/client_prvmsg.c.
795 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Added silc_server_packet_queue_purge call to the
798 silc_server_disconnect_remote to assure that all data in the
799 queue before disconnecting is sent to the network. Affected
802 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
804 * Added the deleting of server's own ID cache entry to the
805 silc_server_free function. Free also everything else that
806 has been allocated in silc_server_init. The affected file
809 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
811 * Added functions silc_parse_version_string, silc_version_to_num,
812 and silc_ske_parse_version to parse SILC protocol style version
813 strings. Affected files lib/silcutil/silcutil.[ch] and
814 lib/silcske/silcske.[ch].
816 * Added new configuration params: version_protocol, version_software
817 and version_software_vendor to specify what version the remote
818 host must at least be to be able to connect to server. The vendor
819 string can be regex matched too. Added new function
820 silc_server_connection_allowed to check maximum number of allowed
821 connections, and allowed versions for incoming connections.
822 Affected files are silcd/server.c, server_util.[ch] and
825 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
827 * Added preliminary support for signals in scheduler. The
828 signals we care about are now blocked always when the scheduler
829 is locked. This way we can synchronise the use of signal with
830 scheduler. It is guaranteed that when signal occurs the scheduler
831 is not locked, and thus new tasks can be safely added to the
834 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
835 to silc_schedule_internal_init and silc_schedule_internal_uninit.
836 Added new platform specific routines
837 silc_schedule_internal_signals_[un]block and
838 silc_schedule_internal_signal_[un]register.
840 Added new functions to SILC Schedule API:
841 silc_schedule_signal_[un]register. Each signal that application
842 is going to use should be registered to the scheduler.
844 Affected files are lib/silcutil/silcschedule.[ch],
845 lib/silcutil/*/silc*schedule.c.
847 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
849 * Check for unauthenticated client and server in the
850 silc_server_new_client and silc_server_new_server functions.
851 Affected file silcd/packet_receive.c.
853 * Added function silc_string_is_ascii to check whether given
854 string is 7-bit ASCII string. Affected files are
855 lib/silcutil/silcutil.[ch].
857 * Added function silc_id_is_valid_server_id into the
858 silcd/serverid.c and added checking for valid Server ID's in
859 silc_server_new_server. The Server ID must always be based
860 on the server's public IP address.
862 * Added logging of DISCONNECT packet message in the server.
863 Affected file silcd/server.c.
865 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
867 * Changed all library interfaces that use Global RNG to also
868 accept SilcRng as argument. Affected files are
869 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
870 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
871 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
872 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
875 * Added function silc_pkcs_generate_key to the
876 lib/silccrypt/silcpkcs.[ch] for applications so that they
877 don't need to do pkcs->pkcs->init calls anymore.
879 * Remove SilcSocketConnection from the SFTP API since it really
880 wasn't needed there. The application has the information
881 saved in its contexts anyway and the SFTP layer doesn't need
882 know about it. Affected files lib/silcsft/silcsftp.h and
883 lib/silcsftp/sftp_[server/client].c.
885 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
886 The SilcSimContext is not SilcSim.
888 * Fixed possible buffer overflows in silc_id_render in the
889 lib/silcutil/silcutil.c.
891 * On EPOC the global crypto module lists are not used at all
892 in the crypto library. Added support for using the constant
893 algorithm list on EPOC. Affected files are
894 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
897 * Fixed the handling of third parameter of KICKED notify, since
898 it was mistakenly updated to SILC Protocol 1.0 even though it
899 is to be included in 1.1. Since it is not in 1.0 it is not
900 mandatory, and this fix now handles it only if it is provided,
901 and it is not error if it is not provided. Affected file
902 lib/silcclient/client_notify.c.
904 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
906 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
907 client. Affected file irssi/src/silc/core/client_ops.c.
909 * Merged with Irssi 0.8.4 from irssi.org CVS.
911 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
913 * Check for valid socket connection in client entries before
914 sending any messages. Fixes a crash, but doesn't fix some
915 other underlaying bug that is lurking there. Affected
916 file silcd/packet_send.c.
918 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
920 * $usermode, $cumode and $cumode_space expandos shouldn't do
921 anything with non-SILC server records. Affected file
922 irssi/src/silc/core/silc-expandos.c
924 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
926 * Fixed the silc_net_check_[host/local]_by_sock to support
927 IPv6 bound sockets as well. Now they can return IPv6 addresses
928 as well. Affected file lib/silcutil/silcnet.c.
930 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
931 Affected lib/silcutil/unix/silcunixnet.c.
933 * Fixed ID rendering (at least on some platforms, not NetBSD)
934 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
936 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
938 * Added silc_hash_public_key and silc_hash_public_key_compare
939 functions to be used with SilcHashTable. They can be used to
940 hash public keys and compare public keys in hash table. Affected
941 file lib/silcutil/silcutil.[ch].
943 * Added support for specifying multiple public keys for Client
944 connection section in server configuration file. This makes it
945 possible to accept multiple public keys from same host, or to
946 make a section that accepts any incoming host, and have the
947 accepted public keys listed in the section.
949 Added functions silc_sever_[find/get]_public_key, added the
950 support for this actually to all connection sections but only
951 the Client section is currently allowed to specify multiple
954 Affected files are silcd/server.c, server_internal.h,
955 command.c, protocol.c, server_util.[ch], packet_receive.c.
957 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
959 * Merged Irssi 0.8.2 from irssi.org CVS.
961 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
963 * If silc_debug is TRUE, also output standard logging messages
964 to stderr with the debug output.
966 Made silc_log_reset_all() flushing all channels before returning.
967 Also fixed some documentation typos.
969 Affected files are lib/silcutil/silclog.[ch].
971 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
973 * Fixed the server to check correctly the amount of connections
974 from single host, by checking also the type of the connection.
975 Fixed also the comparison of number of connections and number
976 of allowed connections. Affected files are silcd/server.c,
979 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
981 * Fixed the USERS command reply to save the user's mode on the
982 channel as well. Fixed JOIN command reply to check whether a
983 client is on channel already and not join it twice. Affected
984 file lib/silcclient/command_reply.c.
986 * Added new file silc-expandos.c into irssi/silc/core/ to return
987 various stuff for various signal for the statusbar etc. updating.
988 Now Irssi SILC client prints channel user modes etc. on the
991 * The user mode (like server/router operator changes) is now shown
992 on the Irssi SILC client's statusbar. The affected files are
993 irssi/src/silc/core/client_ops.c, silc-expandos.c.
995 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
997 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
998 to SILC_SCHEDULE_[UN]LOCK macros.
1000 * Added more error printing to logs in server code. Affected
1001 files silcd/server.c and silcd/protocol.c.
1003 * Fixed -S option parsing in Irssi SILC Client. Affected file
1004 irssi/src/silc/core/silc-core.c.
1006 * Added silc_buffer_alloc_size function. Affected file is
1007 lib/silcutil/silcbuffer.h.
1009 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1011 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1012 constants. Affected files in
1013 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1016 * Changed the internal SFTP Memory FS table to const. Affected
1017 file lib/silcsftp/sftp_fs_memory.c.
1019 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Fixed the buffer formatting and unformatting routines to
1022 check the size of 64 bits types with sizeof(). Affected
1023 file is lib/silcutil/silcbuffmt.c.
1025 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1032 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1033 to avoid collisions with other libraries using same type names
1036 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1038 * Added `prefer_ipv6' argument to the functions
1039 silc_net_gethostbyname[_async]. If it is TRUE it will return
1040 IPv6 address over IPv4. If FALSE IPv4 address is returned
1041 even if IPv6 address was found. Affected files
1042 lib/silcutil/silcnet.[ch].
1044 * Added support silc_net_create_connection[_async] to fallback
1045 to IPv4 address if IPv6 address could not be used (like if
1046 it doesn't work on a specific system). Affected file in
1047 lib/silcutil/unix/silcunixnet.c.
1049 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1055 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1057 * Added automatic extern "C" { ... } for C++ compilers so the
1058 application does not need to define them. Affected file
1059 includes/silcincludes.h.
1061 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1062 old name went against naming convention. Applications now
1063 include "silcclient.h" instead of "clientlibincludes.h".
1064 Removed includes/clientlibincludes.h, it is redundant now.
1066 * Renamed includes/version.h to silcversion.h.
1068 * Added really preliminary support for OS/2 into the util
1069 library. Only thread & mutex API is implemented, others
1070 are still to be implemented. Created the lib/silcutil/os2/
1071 directory. Created also file includes/silcos2.h.
1073 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1077 functions to support SILC on BeOS. Created also file
1078 includes/silcbeos.h.
1080 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1082 * Added proper initializations to silc's irssi code, so it's
1083 now possible to load it as module. Affected files
1084 irssi/src/silc/core/silc-core.c,

1104 * Added `user_count' to the SilcChannelEntry which now tells the
1105 number of users on the channel. The user count is now saved
1106 in normal server of global channels as well. Affected files
1107 silcd/server.c, idlist.h, packet_receive.c and command.c.
1109 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1110 include file utility functions.
1112 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1113 instead of calling directly OS routines.
1115 * Fixed NICK change printing in Irssi SILC Client. Fixed
1116 KICKED notify printing in Irssi SILC Client. Affected file
1117 irssi/src/silc/core/client_ops.c.

1125 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1126 the SKE interface a bit.
1128 * Fixed padding problem in PKCS#1. The padding was not actually
1129 random since the random number generator was used incorrectly.
1130 This security bug affects only when encrypting with PKCS#1, and
1131 it is not currently used at all in SILC. SILC only use signing
1132 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1134 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1144 * Added following new config file settings:
1145 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1146 key_exchange_timeout, conn_auth_timeout, connections_max,
1149 Implemented all the new config settings handling in the server.
1151 Optimized the use of SKE Mutual flag usage. Use it only
1152 if connection authentication protocol is not based in public
1155 Renamed all SilcServerConfigSection* to SilcServerConfig*
1156 to have a bit shorter names.
1158 Affected files silcd/serverconfig.[ch], server.[ch], and

1187 Affected files are silcd/serverconfig.[ch].
1189 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1191 * Fixed command line parameter handling. All SILC initialization
1192 is now done in silc_core_init() which also fixes autoconnecting
1195 Affected files irssi/src/silc/core/silc-core.c,
1196 irssi/src/fe-text/silc.c.
1198 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Added new configuration options and blocks:
1201 keepalive_secs, reconnect_count, reconnect_interval,
1202 reconnect_interval_max, reconnect_keep_trying and
1203 require_reverser_lookup. Added ConnectionParam block, and
1204 implemented the connection parameters when connecting as
1205 initiator and when accepting connections as responder.

1217 the connection configuration object from the SilcServerConnection
1218 object instead of finding it during the connecting phase.
1219 Added the configuration object to SilcServerConnection struct.
1220 Affected files silcd/server_internal.h, server.c.
1222 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1224 * Add the client on channel after it was resolved at the
1225 channel message receiving, and it was not already on the
1226 channel. Affected file lib/silcclient/client_channel.c.
1228 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1244 authentication to be set at the same time.
1246 Added `prefer_passphrase_auth' setting in config file which
1247 can be used to set to prefer passwd auth if both passwd and
1248 public key is set. If not set, public key is preferred.
1249 This has effect only when being initiator (responder will try
1252 Added support for authentication with passphrase and public key
1253 at the same time. The passphrase is tried first always since
1254 it is faster to check.
1256 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1258 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1304 * Fixed the file transfer's key agreement payload to include
1305 zero port also if the hostname is NULL because it could not
1308 Call file transfer monitor callback now also if error occurs
1309 during key agreement protocol.
1311 Changed the silc_client_file_send interface to return the
1312 SilcClientFileError instead of session id. The session ID
1313 is returned into pointer provided as argument.
1315 Check that the file exists locally before sending the
1316 file transfer request at all.
1318 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1320 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer

1330 file lib/silcutil/silclog.c.
1332 * Fixed the channel message payload decryption in the function
1333 silc_channel_message_payload_decrypt to not modify the original
1334 buffer before it is verified that the message decrypted
1335 correctly. Otherwise, next time it is called with correct
1336 channel key it won't encrypt since the payload is corrupted.
1337 Affected file lib/silccore/silcchannel.c.
1339 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1352 the table with foreach callback. The current entry may
1353 become invalid in the callback but it was referenced after
1354 the callback returned.
1356 Do not allow auto rehashing of hash table during the
1357 silc_hash_table_foreach operation, for same reasons as it is
1358 not allowed for SilcHashTableList. Affected files are
1359 lib/silcutil/silchashtable.[ch].
1361 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

1367 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1369 * Fixed private message handling. It used some old code that
1370 caused the client to crash. Affecte file is
1371 lib/silcclient/client_prvmsg.c.
1373 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1375 * Added function silc_client_add_channel,
1376 silc_client_replace_channel_id, and removed functions
1377 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1378 from client library.
1380 * Added cross reference of the joined channels to the

1382 users list to SilcHashTable. The affected files are
1383 lib/silcclient/idlist.[ch].
1385 * Fixed a bug in hash table tarversing. While the hash table
1386 is traversed with SilcHashTableList the table must not be
1387 rehashed. It is now guaranteed that auto rehashable tables
1388 are not rehashed while tarversing the list. Also defined that
1389 silc_hash_table_rehash must not be called while tarversing
1390 the table. Added function silc_hash_table_list_reset that must
1391 be called after the tarversing is over. The affected files are
1392 lib/silcutil/silchashtable.[ch].
1394 * Changed all hash table traversing to call the new
1395 silc_hash_table_list_reset in server and in client library.
1397 * Added function silc_client_on_channel to return the
1398 SilcChannelUser entry if the specified client entry is joined
1399 on the specified channel. This is exported to application as
1400 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1402 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1405 server. The notify for mode change must be sent always and
1406 not only if !cmd->pending. Affected file silcd/command.c.
1408 * Fixed the WHOWAS command's reply sending to support the
1409 lists correctly. Affected file silcd/command.c.
1411 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1413 * When sending JOIN command to router for processing the
1414 sender's old command identifier was not saved back to the
1415 sender's command context, fixed now. The affected file is
1418 * Create the key in JOIN command of the router did not return
1419 the channel key, added check for this. Affected file is
1422 * Fixed a channel ID update bug in JOIN command reply. Do
1423 not directly upgrade the ID but call the function
1424 silc_idlist_replace_channel_id if the ID was changed.
1425 Affected file silcd/command_reply.c.
1427 * Fixed memory leaks from command calling if it would fail.
1428 Affected file silcd/command.c.

1455 functions. Affected file silcd/server.c.
1457 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1458 which ID was changed. This way the router will send the
1459 user list for the channel again, and server won't be in
1460 desync in some rare circumstances. Affected file is
1461 silcd/packet_receive.c.
1463 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1510 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1512 * Fixed the NICK command to always give the unformatted
1513 nickname to the one giving the NICK command. If unformatted
1514 nickname is cached already it will be formatted and the
1515 local entry will always get the unformatted nickname.
1516 Affected file lib/silcclient/idlist.c.
1518 * Fixed some double frees from client library commands.
1519 Affected file is lib/silcclient/command.c.
1521 * Fixed CUMODE command in server to assure that no one can
1522 change founder's mode than the founder itself, there was a
1523 little bug. Affected file silcd/command.c.
1525 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1527 * Removed the SilcClientCommandDestructor from the client
1528 libary, it is not needed anymore. Affected files are
1529 lib/silcclient/silcapi.h, command[_reply].[ch],
1530 client_notify, idlist.c.
1532 * Fixed GETKEY command to first resolve client, and then

1535 lib/silcclient/command.c.
1537 * Added silc_client_start_key_exchange_cb and lookup the
1538 remote hostname and IP address before starting the key
1539 exchange with server. The affected file is
1540 lib/silcclient/client.c.
1542 * The server's public key is now saved using the IP address
1543 of the server and not the servername for the filename.
1544 The hostname public key filename is checked as an fall back
1545 method if the IP address based filename is not found.
1547 Fixed the GETKEY command to save the fetched server key
1548 in correct filename.
1550 Print the remote server's hostname now when new key is
1551 received during connection process. Affected file is
1552 irssi/src/silc/core/client_ops.c.
1554 * Return always our own public key to the client if it asks
1555 for it with GETKEY command. Affected file silcd/command.c.
1557 * Removed the use_auto_addr variable from default config
1558 file since it was in wrong section. Affected file is
1561 * Fixed TOPIC_CHANGE notification to not route it when it
1562 was sent using silc_server_send_notify_to_channel function.
1563 Affected file silcd/command.c.
1565 * Fixed silc_server_send_notify_kicked to send the kicker's
1566 Client ID also, it was missing. Affected files are
1567 silcd/command.c, silcd/packet_send.[ch].
1569 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1571 * Do not save client history information in SERVER_SIGNOFF.
1572 Fixes the bug in normal server that it does not detect
1573 the client becoming valid after the server becomes back
1574 online. Affected file silcd/server_util.c.
1576 * Added `sock_error' field into the SilcSocketConnection
1577 context. When error occurs during socket operation (read
1578 or write) the error is saved. Added also new function
1579 silc_socket_get_error to return human readable socket error
1580 message. Affected files are lib/silcutil/silcsockconn.[ch],
1581 lib/silcutil/unix/silcunixsockconn.c, and
1582 lib/silcutil/win32/silcwin32sockconn.c.
1584 * The server now prints the socket error message in the
1585 signoff for client. Affected file silcd/server.c.
1587 * Fixed the `created' channel information sending from router
1588 to server in JOIN command. Checks now whether the channel
1589 really was created or not and set it according that.
1591 Fixed the JOIN command to use the client entry's current
1592 ID during the joining procedure instead of the one it sent
1593 in the command (it is checked though), since it can change
1594 between the packet processing and command processing, and
1595 would just case unnecessary pain in the client end. Affected
1596 file silcd/command.c.
1598 * Fixed a channel key payload sending to use correct channel
1599 ID when the server was forced to change the channel's ID by
1600 router. Router sent the key payload with the old Channel ID.
1601 Affected file silcd/packet_receive.c.
1603 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Call silc_server_save_channel_key only if the key payload
1606 was provided in the JOIN command's command reply. Affected
1607 file silcd/command_reply.c.
1609 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1611 * Fixed silc_mp_sizeinbase to return the value correctly with
1612 MPI. Affected file lib/silcmath/mp_mpi.c.
1614 * Fixed the stop_server signal to correctly stop the scheduler
1615 and gracefully stop the server when SIGTERM or SIGINT signals
1616 are received. Affected file silcd/silcd.c.
1618 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1620 * Simple handling of TERM and HUP signals. Also added some log
1621 flushing call around. Affected file is
1624 * Fixed small bugs in silclog.c. Now buffering output will take
1625 effect after 10 seconds since startup: This will ensure that
1626 no important startup messages are lost. Also output redirection
1627 will preserve original format ([Date] [Type] message).
1628 Affected file is lib/silcutil/silclog.c.
1630 * Added two options to the config file, in the logging section:
1631 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1632 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1634 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Do not print the warning about log files not being initialized
1637 more than once to avoid excess logging. Affected file is
1638 lib/silcutil/silclog.c.
1640 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1641 the SIM copying in make install in Makefile.am.pre.
1643 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1645 * Rewritten silclog APIs. Globally interesting changes follows:
1646 silc_log_set_files() changed to silc_log_set_file().
1647 silc_log_set_callbacks() changed to silc_log_set_callback().
1648 ROBOdoc documented silclog header file.
1649 SilcLogCb now returns bool to wether inihibit the default
1650 handler or not (to keep the old behaviour return always TRUE).
1651 The new APIs should also fix the problem of the
1652 silcd_error.log file that was written in the current directory.
1655 Log files streams will remain opened after silc_log_set_file()
1656 call, means less CPU usage notably on high traffic servers.
1657 File streams are now full buffered, and flushed to the disk
1658 every 5 minutes, lesses HD activity and CPU usage.
1659 Messages can be redirected, allowing admins to configure
1660 one single logfile for all server messages.
1661 the silc_log_quick global variable to activate fast-logging.
1662 Affected files lib/silcutil/silclog.[ch]
1664 * Changed some code to conform new silclog APIs. Affected
1665 files are doc/example_silcd.conf.in, silcd/server.c
1666 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1669 * Fixed a memory leak that could occur in some situations.
1670 Affected file silcd/serverconfig.c.
1672 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1674 * Added the silc_client_del_client to remove the client from
1675 all channels as well. Affected file lib/silcclient/idlist.c.
1677 * Fixed the client library to correctly remove the client
1678 from all channels when the client entry is being destroyed.
1679 Affected file lib/silcclient/client_notify.c, command.c.
1681 * Added auto-nicking support to the client library. If the
1682 applicatio now sets client->nickname it will be sent to the
1683 server after connecting by the library. This way for example
1684 SILCNICK (or IRCNICK) environment variables will have effect
1685 and always change the nickname automatically to whatever
1686 it is wanted. Affected file lib/silcclient/client.[ch].
1688 * Renamed silc_server_command_bad_chars to the
1689 silc_server_name_bad_chars and moved it to the
1690 silcd/server_util.[ch]. Added also new function
1691 silc_server_name_modify_bad to return nickname that
1692 includes bad characters as new nickname without those
1693 bad characters. This check and modify is now used in
1694 silc_server_new_client when the username is initially set
1695 as nickname, so it must be checked to be valid nickname.
1696 Affected file silcd/packet_receive.c.
1698 * The nickname length is now taken from the packet for real
1699 and not trusted to strlen() since it clearly can return
1700 wrong length for nickname including bad characters. This
1701 also applies to channel names. Affected file silcd/command.c.
1703 * Removed the lib/silcsilm/modules directory. Modules are now
1704 compiled into the lib/silcsim. Fixed the copying of the
1705 modules to follow symbolic links in Makefile.am.pre.
1707 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1709 * Fixed silc_string_regexify list creation. Fixes bugs with
1710 BAN and INVITE commands in server. The affected file is
1711 lib/silcutil/unix/silcunixutil.c.
1713 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1715 * Removed the command destructor entirely from the server's
1716 command and command reply routines. It is not needed, and
1717 its usage was buggy and caused crashes. Affected files are
1718 silcd/command[_reply].[ch].
1720 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Cancel protocol and NULL sock->protocol if timeout
1723 occurred during protocol. Affected file silcd/server.c.
1725 * Cancel protocol timeouts always before calling the final
1726 callback, to assure that after final callback is called
1727 no other state will be called for the protocol anymore.
1728 Affected file silcd/protocol.c.
1730 * Print error log if incoming connection configuration could
1731 not be found. Affected file silcd/server.c.
1733 * Fixed JOIN command to correctly save the founder mode
1734 to the client on normal SILC server, when the channel
1735 was created by the router. Affected file silcd/command.c.
1737 * Fixed LIST command (hopefully) to send correct reply
1738 packets. Affected file silcd/command.c.
1740 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * The silc_packet_receive_process now returns FALSE if the
1743 read data was invalid packet, and TRUE if it was ok.
1745 The server now checks that if unauthenticated connection
1746 sends data and its processing fails the server will close
1747 the connection since it could be a malicious flooder.
1749 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1751 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1753 * Make sure the warning about error opening a log file is
1754 printed only once and not everytime it fails (produces
1755 too much useless log). Affected file lib/silcutil/silclog.c.
1757 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1759 * Made the silc_server_daemonise() function more readable.
1760 Affected file silcd/server.c.
1762 * Pid file is now optional, the user may comment it out from
1763 the config file. Removed define SILC_SERVER_PID_FILE, we
1764 don't need a default any longer. Affected file
1765 configure.in.pre, lib/Makefile.am.pre.
1767 * Make some use of the pid file. The server now dies at startup
1768 if it detects a valid pid file on his path. The server would
1769 die anyway in this circumstance, because of the bind() failure.
1770 Affected file silcd/silcd.c.
1772 * No longer compiling lib/dotconf.
1774 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1776 * Fixed JOIN command parsing not to crash. Affected file
1777 lib/silcclient/command.c.
1779 * Fied the NICK_CHANGE notify to add the new client entry
1780 even it is resolved. This removes an <[unknown]> nick
1781 thingy bug in the client. Affected file is
1782 lib/silcclient/client_notify.c.
1784 * Do not try to allocate 0 bytes (efence does not like it)
1785 in lib/silccore/silccomand.c when encoding payload.
1787 * Do not take IRCNICK as nickname in Irssi SILC client since
1788 it is not possible to set nickname before hand connecting
1789 the server (TODO has an entry about adding auto-nicking
1792 * Changed the silc_server_command_pending to check whether
1793 there already exists an pending entry with the specified
1794 command, command identifier and pending callback. This is
1795 to fix IDENTIFY and WHOIS related crashes that may register
1796 multiple pending commands with same identifier. Affected
1797 file silcd/command.c.
1799 * Fixed the server to reconnect to the router even if it
1800 was already reconnecting and EOF was received. This to
1801 fix a possibility that the server wouldn't ever try to
1802 auto-reconnect to the router. Affected file silcd/server.c.
1804 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Fixed the server's password authentication to use the
1807 length of the locally saved password, and not the one
1808 sent in the packet. Affected file silcd/protocol.c.
1810 * Fixed same password authentication problem in the
1811 Authentication Payload handling routines in
1812 lib/silccore/silcauth.c.
1814 * Yet another password authentication problem fixed with
1815 channel password handling in silcd/command.c.
1817 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * If first character of string in silc_parse_userfqdn is '@'
1820 then do not parse it. Affected file is
1821 lib/silcutil/silcutil.c.
1823 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Fixed minor bug in IDENTIFY command reply sending, which
1826 caused various weird problems during JOIN when it was
1827 resolving names for users. Affected file silcd/command.c.
1829 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1831 * Fixed the IDENTIFY command reply sending to chech better valid
1832 clients. It was possible to send incomplete list of replies.
1833 Affected file silcd/command.c.
1835 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1837 * Added silc_client_command[s]_[un]register functions now to
1838 dynamically register the commands in client library. Removed
1839 the static table of commands. This allows the client library
1840 to call commands without causing the application to know about
1841 what commands library has called.
1843 Removed the INFO command reply kludge to detect when the command
1844 was called by library. Now library use its own command reply
1845 function for INFO command.
1847 Added function silc_client_command_call to call a command.
1848 Application can use it to call command, not access the structure
1851 Now all commands that are sent by the client library (not
1852 explicitly sent by application) use own command reply functions.
1854 Affected files around lib/silcclient/ and in
1855 irssi/src/silc/core/.
1857 * Fixed the WHOIS command reply sending to chech better valid
1858 clients. It was possible to send incomplete list of replies.
1860 Fixed the WHOIS and IDENTIFY to send the request to router
1861 if normal server did not do it and did not find any results.
1863 Affected file silcd/command.c.
1865 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1867 * Moved the internal data from SilcClient context into its
1868 own file, not accesible to application. Affected files
1869 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1870 and other files in client library.
1872 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1874 * Added doc/examples installation target in Makefile.am.pre.
1877 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1879 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1880 commands the found client entry will be removed from the
1881 cache, after notifying application about the error. Affected
1882 file lib/silcclient/command_reply.c.
1884 * Changed the /MSG to check for exact nickname user gave, and
1885 not let `nick' match `nick@host' if it is only one found. Now,
1886 user must type the exact nickname (like nick@host2) even if
1887 there are no more than one same nicks found. This is to avoid
1888 a possibility of sending nickname to wrong nickname since
1889 `nick' could match `nick@host'. Affected file is
1890 irssi/src/core/silc-servers.c.
1892 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Do not print "you are now server operator" or similar when
1895 giving /away command. Affected files are
1896 irssi/src/silc/core/client_ops.c, silc-servers.h.
1898 * Made the silc_server_command_pending_error_check to send
1899 the same command reply payload it received back to the
1900 original sender of the command. This way all arguments
1901 that was received by the server will be received by the
1902 client too. Affected file silcd/command.c.
1904 * Added the silc_idcache_add to return the created cache entry
1905 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1907 * Add global clients to expire if they are not on any channel.
1908 This is because normal server will never know if they signoff
1909 if they are not on any channel. The cache expiry will take
1910 case of these entries. This is done by normal servers only.
1911 The affected files are silcd/command_reply.c,
1912 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1914 * If server receives invalid ID notification for WHOIS or
1915 IDENTIFY and the ID exists in the lists, it is removed.
1916 Affected file silcd/command_reply.c.
1918 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1919 in client then client entry that it matches is searched and
1920 the nickname is printed on the screen for user. Affected
1921 file irssi/src/silc/core/client_ops.c.
1923 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1925 * Use cache entry expire time in the LIST command reply to
1926 purge old entries from the cache after the LIST command
1927 reply has been received. This way we don't have non-existent
1928 entries in the cache for too long. Affected file is
1929 silcd/command_reply.c.
1931 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1933 * If we are normal server, and we've not resolved client info
1934 in WHOIS or IDENTIFY from router, and it is global client,
1935 we'll check whether it is on some channel. If it is not
1936 then we cannot be sure about its validity and will resolve it
1937 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1938 file silcd/command.c.
1940 * Search channel by name (if possible) rather than by ID
1941 in IDENTIFY command's command reply. Affected file is
1942 silcd/command_reply.c.
1944 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1946 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1947 Updated specs and implemented it. Affected file silcd/command.c,
1948 silcd/packet_send.c and silcd/packet_receive.c.
1950 * Implemented the <founder auth> payload handling in the JOIN
1951 command. If provided all conditions for channel joining
1952 except requirement to provide correct passphrase can be
1953 overrided by the channel founder. Updated the protocol specs.
1954 Affected file silcd/command.c.
1956 Added support for founder auth in JOIN command in client
1957 library. Fixed the parsing of the JOIN command now to support
1958 all options as they should be. The affected file is
1959 lib/silcclient/command.c.
1961 * Optimized the WHOIS and IDENTIFY commands to send the request
1962 to router only if it includes nicknames or other names. If
1963 they include only IDs then check the local cache first before
1964 routing. Affected file is silcd/command.c.
1966 * Added channels topic announcements. Affected file is
1967 silcd/packet_receive.c and silcd/server.c.
1969 * Fixed the silc_server_send_notify_topic_set to really destine
1970 the packet to channel. Affected file silcd/packet_send.c.
1972 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1973 library. Affected file lib/silcclient/client_notify.c.
1975 * Added UMODE announcements. Affected file silcd/server.c.
1977 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Memory leak fixes in:
1981 lib/silcutil/silcsockconn.c
1982 lib/silcske/silcske.c
1983 lib/silcske/groups.c
1985 lib/silccrypt/silcpkcs.c
1986 lib/silccore/silccommand.c
1987 lib/silccore/silcidcache.c
1992 * ROBOdoc documented the lib/silcske/groups.h file and a
1993 bit changed the interface for better.
1995 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1997 * Update the client entry context in the ID cache after
1998 nick change. Affected file lib/silcclient/command.c.
1999 Fixes the CUMODE command when regaining founder privileges,
2000 and a little WHOIS problem.
2002 * Fixed silc_net_gethostbyname to correctly call the
2003 inet_ntop. Affected file lib/silcutil/silcnet.c.
2005 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2007 * Added IPv6 support checking to the configure.in.pre, added
2008 also --enable-ipv6 option to override the check. Affected
2009 file configure.in.pre.
2011 * The silc_thread_create now calls the start function
2012 directly if threads support is not compiled in. Removes
2013 ugly #ifdef's from generic code. Affected files are
2014 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2016 * Added silc_net_gethostby[name/addr]_async to asynchronously
2017 resolve. Affected files are lib/silcutil/silcnet.[ch].
2019 * Added support for rendering IPv6 based server, client and
2020 channel IDs. Affected file lib/silcutil/silcutil.c.
2022 * Added support for creating IPv6 based server IDs. Affected
2023 file is silcd/serverid.c.
2025 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2027 * Added silc_net_gethostby[addr/name] into the
2028 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2029 routines. Added silc_net_is_ip[4/6]. Affected file is
2030 lib/silcutil/unix/silcunixnet.c. All routines that take
2031 address as argument now supports both IPv4 and IPv6 addresses.
2033 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2035 * Fixed LIST command reply sending in server. Affected file
2038 * Server now sends the kicker's client ID in the KICK notify
2039 to the kicked client. Affected file silcd/command.c.
2041 * The client library now parses the kickers client ID and
2042 UI displays it. Affected files lib/silcclient/client_notify.c
2043 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2045 * Made all payload parsing function prototypes consistent.
2046 They all take now const unsigned char * and uint32 pair as
2047 the payload data instead of SilcBuffer. Changes all around
2048 the source tree. Other unsigned char* -> const unsigned char*
2049 changes around the tree as well.
2051 * Optimized SFTP client and server packet sending not to
2052 allocate new buffer for each packet but to recycle the
2053 first allocated buffer. Affected files are
2054 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2056 * Optimized the SFTP client to use SilcList instead of
2057 SilcDList for requests, because it is faster. Affected file
2058 is lib/silcsftp/sftp_client.c.
2060 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2061 into lib/silccore/silcid.[ch].
2063 Renamed silcpayload.[ch] into silcargument.[ch].
2065 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * If client entry is deleted with active key agreement
2068 session, abort the session.
2070 The silc_client_abort_key_agreement now calls the completion
2071 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2073 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2076 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2078 * Don't use __restrict in older GCC's. Affected file is
2079 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2081 * silc_net_localhost now attempts to reverse lookup the
2082 IP/hostname. Affected file lib/silcutil/silcnet.c.
2084 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2085 command. It can be used to gain founder privileges at
2086 the same time when joining the channel.
2088 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2089 kicker's client ID as well. Updated protocol specs.
2091 Defined that the server must send SILC_COMMAND_IDENTIFY
2092 command reply with error status to client who sent
2093 private message with invalid client ID.
2095 Updated the protocol specification.
2097 * Added silc_server_send_command_reply to send any
2098 command reply. Affected file silcd/packet_send.[ch].
2100 * Added silc_id_payload_encode_data to encode ID payload
2101 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2103 * The server now send IDENTIFY command reply with error
2104 status if client ID in private message is invalid. Affected
2105 file silcd/packet_receive.c.
2107 * Save the server key file with server's IP address in
2108 the filename instead of hostname. The affected file is
2109 irssi/src/silc/core/client_ops.c.
2111 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2113 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2116 * Added libtool support for compiling shared objects in
2117 lib/silcsim. Affected file configure.in.pre and
2118 lib/silcsim/Makefile.am. Original patch by cras.
2120 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * Pid file configuration, and server's config file fixes
2123 patch by toma. Updated CREDITS file.
2125 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2127 * Fixed silc_client_channel_message to not try to decrypt
2128 the message twice if it resolved the destination client
2129 information. This could cause of dropping one channel
2130 message. Affected file lib/silcclient/client_channel.c.
2132 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2135 lib/silcclient/client.c. This function is used when the SILC
2136 Client is run under some other scheduler, or event loop or
2137 main loop. On GUI applications, for example this may be
2138 desired to used to run the client under the GUI application's
2139 main loop. Typically the GUI application would register an
2140 idle task that calls this function multiple times in a second
2141 to quickly process the SILC specific data.
2143 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2145 * Fixed silc_server_drop() for dropping the supplementary
2146 groups as well, this could cause a security hole on some
2149 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2151 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2154 * Write PID file after dropping privileges. Added -F option
2155 to run server on foreground. A patch by debolaz.
2156 Affected files silcd/server.c, silcd/silcd.c.
2158 * Fixed MOTD to return the MOTD file server name. Affected
2159 file silcd/command.c.
2161 * Added INFO command reply handling to the Irssi SILC Client.
2162 Affected file irssi/src/silc/core/client_ops.c.
2164 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2166 * Fixed the silc_idcache_list_* routines to really support
2167 the dynamic list. Fixes a crash. Affected file is
2168 lib/silccore/silcidcache.c.
2170 * Fixed the LIST command reply to really call LIST command's
2171 pending callbacks. Affected file silcd/command_reply.c.
2173 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Update conn->local_entry->nickname after giving NICK
2176 command. Affected file lib/silcclient/command.c.
2178 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2180 * Added the [pid] option to the silcd configuration file
2182 Affected files: serverconfig.[ch] and silcd.c
2184 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2186 * Save fingerprint in WHOIS command reply in server.
2187 Affected file silcd/command_reply.c.
2189 * Fixed NICK commands pending callback registration.
2190 Affected file lib/silcclient/command.c.
2192 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2194 * Use ++server->cmd_ident when sending commands in server,
2195 instead of random number. Affected file silcd/command.c.
2197 * Fixed GETKEY command reply to call actually GETKEY pending
2198 command callbacks. Affected file silcd/command_reply.c.
2200 * A bit stricter check for nicknames. Check for same nickname
2201 in NICK command also. Affected file silcd/command.c.
2203 * Do not call INFO command everytime client ID changes, only
2204 during first connecting. Affected file lib/silcclient/client.c.
2206 * Set the new nickname only after successful command reply for
2207 NICK command is returned by server. Affected file
2208 lib/silcclient/command.c.
2210 * Remove nicknames from nicklist during server_signoff notify.
2211 Should fix /NAMES bit more. The affected file is
2212 irssi/src/silc/core/silc-channels.c.
2214 * Added `fingerprint' field to the SilcIDListData in the
2215 silcd/idlist.h to hold the fingerprint of the client's
2218 Send the fingerprint of the client's public key in WHOIS
2221 Affected files silcd/command.c, and silcd/idlist.[ch].
2223 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2224 create fingerprint from given data.
2226 * Show the fingerprint of the client's public key in WHOIS.
2227 Affected files irssi/src/module-formats.[ch] and
2228 irssi/src/silc/core/client_ops.c.
2230 * Format the multiple same nicknames also during JOIN and
2231 NICK_CHANGE notifys. Affected file is
2232 lib/silcclient/client_notify.c.
2234 * Do not print error on screen for invalid private message
2235 payload since it can come if someone is sending private
2236 messages with wrong key. Affected file
2237 lib/silccore/silcprivate.c.
2239 * Fixed multiple concurrent /PING crash. Affected file
2240 lib/silcclient/command.c.
2242 * Changed the wrong ID encoding. All IP addresses must be
2243 in MSB first order in encoded format. They were encoded
2244 wrong and was in LSB format. Affected files are
2245 silcd/serverid.c, lib/silcutil/silcutil.c.
2247 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2249 * Call the `connect' client operation through the scheduler
2250 in case of error. Affected file lib/silcclient/client.c.
2252 * Call the `failure' client operation even if the error
2253 occurred locally during a protocol. Affected file is
2254 lib/silcclient/protocol.c.
2256 * Added support of sending LIST command to router from normal
2257 server. This way normal server can get list of all channels
2258 in the network too. Fixed the channel list sending in the
2259 server too. Affected files are silcd/command.c, and
2260 silcd/command_reply.[ch].
2262 * Added silc_server_update_channels_by_server and
2263 silc_server_remove_channels_by_server. They are used during
2264 disconnection of primary router and in backup router protocol.
2265 Affected file silcd/server_util.[ch], silcd/server.c and
2266 silcd/server_backup.c.
2268 * Fixed channel adding to global list in IDENTIFY command
2269 reply in server. Affected file silcd/command_reply.c.
2271 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * If the incoming packet type is REKEY or REKEY_DONE process
2274 that packet always synchronously. Fixes yet another MAC
2275 failed error on slow (dialup) connections. Affected file
2276 lib/silcclient/client.c and silcd/server.c.
2278 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Call check_version SKE callback for initiator too. Affected
2281 file lib/silcske/silcske.c.
2283 * Implemented fix for security hole found in the SKE that was
2284 fixed in the specification few days back; the initiator's
2285 public key is now added to the HASH value computation.
2286 Added backwards support for the old way of doing it too, for
2287 old clients and old servers. Affected file is
2288 lib/silcske/silcske.c.
2290 * Enabled mutual authentication by default in SKE. If initiator
2291 is not providing mutual authentication the responder will
2292 force it. This will provide the proof of posession of the
2293 private key for responder. The affected files are
2294 lib/silcclient/protocol.c and silcd/protocol.c.
2296 * Do not cache anymore the server's public key during SKE.
2297 We do mutual authentication so the proof of posession of
2298 private key is done, and if the server is authenticated in
2299 conn auth protocol with public key we must have the public
2300 key already. Affected file silcd/protocol.c.
2302 * Added new global debug variable: silc_debug_hexdump. If
2303 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2304 file lib/silcutil/silclog.[ch].
2306 * Fixed compilation warning due to char * -> const char *.
2307 Affected files lib/silcutil/silcnet.h, and
2308 lib/silccore/silcauth.[ch].
2310 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2312 * Fixed CMODE command when new channel key was created. If
2313 the creation failed the old key was removed. Next time giving
2314 same command would crash the server since the old key was
2315 freed already. Affected file silcd/command.c.
2317 * Fixed the silc_server_announce_get_channels to not crash
2318 on reconnect. Affected file silcd/server.c.
2320 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2322 * Added silc_log_set_debug_string function to set a regex
2323 string to match for debug output. Only the function names,
2324 or filenames matching the given debug string is actually
2325 printed. This way it is possible to filter out those debug
2326 strings that user is not interested in.
2328 Fixed a bug in silc_string_regexify.
2330 Affected files lib/silcutil/silclog.[ch], and
2331 lib/silcutil/unix/silcunixutil.c.
2333 * Changed the -d options in both server and Irssi SILC client
2334 to take the debug string as argument. Affected files
2335 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2337 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Added silc_hash_babbleprint to create a Bubble Babble
2340 Encoded fingerprint. The encoding is developed by Antti
2341 Huima (draft-huima-babble-01.txt), and it creates human
2342 readable strings out of binary data. Affected file
2343 lib/silccrypt/silchash.[ch].
2345 * Print the babble print now in addition of fingerprint as well
2346 in Irssi SILC client. Affected files are
2347 irssi/src/fe-common/silc/module-formats.[ch],
2348 irssi/src/fe-common/silc/core/client_ops.c.
2350 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2352 * Fixed a security problem found in SKE. The initiator's
2353 public key too is now added to the HASH hash value creation
2354 which is signed by the responder to create the SIGN value.
2355 This will prevent anyone in the middle to lie to the responder
2356 about the initiator's public key. If this is done now, the
2357 man in the middle will get caught. Updated the protocol
2360 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Better installation directory handling. Configure module
2363 paths and other paths automatically to example_silc* files
2364 in doc/. A patch by toma.
2366 * Fixed compiler warning from MPI library, and from SILC RNG.
2369 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2370 It can be configured with ./configure. A patch by toma.
2372 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Find correct make to use in prepare-clean. A patch by
2375 toma. Affected file prepare-clean.
2377 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2379 * Added irssi variables use_auto_addr, auto_bind_ip,
2380 auto_bind_port and auto_public_ip.
2382 * Changed the interface for silc_client_send_key_agreement
2383 in lib/silcclient/silcapi.h
2387 irssi/src/silc/core/silc-core.c
2389 lib/silcclient/silcapi.h
2390 irssi/src/silc/core/silc-channels.c
2391 lib/silcclient/client_keyagr.c
2394 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Added silc_pkcs_public_key_compare to compare two
2397 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2399 * Check that the client who set the founder mode on the
2400 channel is the same client that is giving the founder
2401 mode to itself. It is done by comparing the saved public
2402 key (it is saved even in the authentication is passphrase).
2403 Affected file silcd/command.c.
2405 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2407 * Do not process packet for disconnected socket connection.
2408 Affected file lib/silccore/silcpacket.c.
2410 * Process the DISCONNECT packet through scheduler in the
2411 client library. Affected file lib/silcclient/client.c.
2413 * Fixed the silc_client_packet_parse to not to increase
2414 the packet sequence number if the conn->sock and the
2415 current socket connection is not same. This can happen
2416 for example during key agreement when the conn includes
2417 multiple socket connections (listeners). Affected file
2418 lib/silcclient/client.c.
2420 * The sender of the file transfer request now provides also
2421 the pointer (listener) for the key exchange protocol. If
2422 the listener cannot be created then it sends empty key
2423 agreement and lets the receiver provide the listener.
2425 Added `local_ip' and `local_port' arguments to the
2426 silc_client_file_send. If they are provided they are used,
2427 if not then it will attempt to find local IP address, if
2428 not found or bind fails then the remote client will provide
2431 Affected files are lib/silcclient/client_ftp.c and
2432 lib/silcclient/silcapi.h.
2434 * Extended the FILE SEND command to support defining the
2435 local IP and port for key exchange listener. They are
2436 optional. Affected file irssi/src/silc/core/silc-servers.c.
2438 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Defined to WHOIS command reply the sending of fingerprint
2441 of the client's public key (if the proof of posession of the
2442 corresponding private key is verified by the server).
2443 Updated to the protocol specification.
2445 * Added support of receiving the client's public key's
2446 fingerprint in command reply in client library. Affected
2447 file is lib/silcclient/command_reply.c, and
2448 lib/silcclient/idlist.[ch].
2450 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Do not send over 128 chars long nickname to the server
2453 in NICK command. Affected file lib/silcclient/command.c.
2455 * Do not send over 256 chars long channel names to the server
2456 in JOIN command. Affected file lib/silcclient/command.c.
2458 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2460 * Assure that silc_server_close_connection cannot be called
2461 twice for same socket context. Affected file is
2464 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2466 * Send error message to application if opening file for
2467 writing during file transfer fails. Affected file is
2468 lib/silcclient/client_ftp.c.
2470 Remove all file transfer sessions for a client that we're
2471 removing from ID cache.
2473 Affected file is lib/silcclient/client_ftp.c.
2475 * Fixed silc_net_addr2bin to return correct address. Affected
2476 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2478 * Fixed file transfer session removing on signoff notify.
2479 Affected file irssi/src/silc/core/silc-servers.c.
2481 * Added the SilcClientFileError to be returned in the monitor
2482 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2483 Affected file lib/silcclient/silcapi.h.
2485 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Fixed a crash in silc_client_ftp_free_sessions and
2488 silc_client_ftp_session_free_client. Affected file
2489 lib/silcclient/client_ftp.c.
2491 * Added `disabled' field in the SilcChannelEntry in the server
2492 to indicate if the server entry is disabled. Affected file
2493 silcd/idlist.h, silcd/command[_reply].c.
2495 * SILC server adds now /var/run/silcd.pid everytime it is
2496 started. Affected file silcd/silcd.c.
2498 * Added silc_server_packet_send_clients to send a packet to
2499 the provided table of client entries. Affected file
2500 silcd/packet_send.[ch].
2502 * Fixed a crash in client resolving in client_prvmsg.c in
2503 client library. Affected file lib/silcclient/client_prvmsg.c.
2505 * Do not actually remove the client directly from ID cache
2506 during SERVER_SIGNOFF, but invalidate it. This way we
2507 preserve the WHOWAS info for the client. Affected file
2508 silcd/server_util.c.
2510 * Fixed SERVER_SIGNOFF notify handling in the server. The
2511 server is now able to process incoming SERVER_SIGNOFF notify
2512 for a server that it doesn't even know about. It will remove
2513 the clients provided in the notify. Affected file
2514 silcd/packet_receive.c.
2516 * Check for partial packet in data queue after every packet that
2517 was found from the queue. Return and wait for more data if
2518 there is partial data in queue. Affected file is
2519 lib/silccore/silcpacket.c.
2521 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Added SilcClietFileError enum to indicate error in
2524 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2525 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2526 Affected files lib/silcclient/silcapi.h and
2527 lib/silcclient/client_ftp.c.
2529 * Check that newsize in silc_buffer_realloc is larger than
2530 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2532 * Added better monitor of file transfers. It now monitors
2533 key agreement protocol during the file transfer too. Added
2534 error reporting too. Affected files
2535 irssi/src/silc/core/silc-servers.c,
2536 irssi/src/fe-common/silc/module-formats.[ch].
2538 * Wrote a help file for FILE command.
2540 * Added silc_rng_global_get_byte_fast to get not-so-secure
2541 random data as fast as possible. Random data is read from
2542 /dev/urandom if available and from the SILC RNG if not
2543 available. It is used in padding generation. Affected file
2544 lib/silccrypt/silcrng.[ch].
2546 * All packets in client library are now processed synchronously.
2547 Optimized packet processing a lot. Affected file
2548 lib/silcclient/client.c.
2550 * All server connection packets are processing synchronously
2551 now in server, to optimize packet processing. Affected file
2554 * Include files are installed now only in Toolkit distribution
2555 if make install is given. Affected files: all Makefile.am's.
2557 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2559 * Assure that silc_client_notify_by_server_resolve does not
2560 resolve the client information multiple times. If it cannot
2561 be found by the first it cannot be found at all. Affected
2562 file lib/silcclient/client_notify.c.
2564 * Fixed WHOWAS command reply calling. Affected file
2565 lib/silcclient/command_reply.c.
2567 * Removed all references to silc_idlist_get_client from the
2568 Irssi SILC client since that call is internal call used by
2569 the library. The Irssi SILC client will use now client
2570 retrieval functions found in silcapi.h.
2572 * Fixed a bug in resolving nickname info before sending
2573 private message. It used freed memory. Affected file
2574 irssi/src/silc/core/silc-servers.c.
2576 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Assure my_channels statistics cannot go negative in server.
2579 Affected files silcd/server.c, silcd/server_util.c.
2581 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2585 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2587 * Win32 Toolkit changes. Affected files
2588 win32/silc.dsw, win32/libsilc/libsilc.def,
2589 win32/libsilcclient/libsilc.def,
2590 lib/silcutil/silcutil.c, and
2591 lib/sftp/sftp_fs_memory.c.
2593 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * Added silc_net_localip to return local host's IP address.
2596 Affected file lib/silcutil/silcnet.[ch].
2598 * If key exchange or rekey protocol is active for a connection
2599 parse all packets syncronously since there might be packets
2600 in packet queue that we are not able to process without first
2601 processing packets before them. Affected file silcd/server,
2602 lib/silcclient/client.c.
2604 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2605 whether library should continue processing the packet.
2606 Affected file lib/silccore/silcpacket.h.
2608 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2632 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2634 * Renamed silc_file_read and silc_file_write to functions
2635 silc_file_readfile and silc_file_writefile. Added function
2636 silc_file_open and silc_file_close. Affected files
2637 lib/silcutil/silcutil.[ch].
2639 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2641 * Resolve the client info when received private message or
2642 channel message for a client which nickname we don't know.
2643 Affected files lib/silcclient/client_prvmsg.c and
2644 lib/silcclient/client_channel.c.
2646 * Do not crash in /KEY if client is not connected. Affected
2647 file irssi/src/silc/core/silc-channels.c.
2649 * Added SilcClientStatus field to the SilcClientEntry in the
2650 lib/silcclient/idlist.h.
2652 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2653 is incomplete and is being resolved, it won't be resolved
2656 Make sure also that USERS command reply does not resolve
2657 twice information. Affected file is
2658 lib/silcclient/command_reply.c.
2660 Make sure that silc_client_get_clients_by_list does not
2661 resolve twice same information.
2663 * Check for valid client->id in the silc_server_free_client_data.
2664 Affected file silcd/server.c.
2666 * Fixed /GETKEY nick@server not to crash if the server entry
2667 is not found. Affected file lib/silcclient/command.c.
2669 * Fixed the silc_server_check_cmode_rights to check the
2670 requested modes correctly. Affected file silcd/command.c.
2672 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * Better checks for non-printable chars in nick added.
2675 Affected file silcd/command.c.
2677 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2679 * Call the silc_server_udpate_servers_by_server in the
2680 primary router that comes back online in the backup resuming
2681 protocol. Otherwise it routes packets wrong. Affected file
2682 silcd/server_util.[ch], silcd/server_backup.c.
2684 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2687 lib/silcutil/silcbuffmt.[ch].
2689 * Redefined the SILC packet header to include the padding
2690 length. Affected file lib/silccore/silcpacket.[ch].
2692 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2693 length for maximum padding up to 128 bytes). Affected
2694 file lib/silccore/silcpacket.h.
2696 * Removed all backwards support for old 0.5.x MAC thingies.
2697 The SILC packet header change makes it impossible to be
2698 backwards compatible.
2700 * Send the ENDING packet with timeout in the backup resuming
2701 protocol. This is to assure that all routers has connected
2702 to the primary router. Affected file silcd/server_backup.c.
2704 * Changed the RNG to take the first IV from random data. It
2705 used to take it from zero actually. Changed the RNG also
2706 to use /dev/urandom during session. /dev/random is used
2707 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2709 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Changed the SILC packet header to have the first two bytes
2712 (the packet length) encrypted. Affected files aroung the
2713 code tree, lib/silccore/silcpacket.[ch]. Removed the
2714 SilcPacketCheckDecrypt callback. It is not needed anymore
2715 since the silc_packet_receive_process will determine now
2716 whether the packet is normal or special.
2718 * Implemented the unidirectional MAC keys. Affected files
2719 lib/silcske/silcske.c, silcd/protocol.c and
2720 lib/silcclient/protocol.c.
2722 * Implemented the packet sequence number to the MAC computation.
2723 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2724 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2725 lib/silcclient/protocol.c.
2727 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2729 * Allow backup router to announce servers. All servers
2730 announced by backup router are added to the global list
2731 automatically. Update hte server's socket to our primary
2732 router also when backup router announces a server.
2733 Affected file silcd/packet_receive.c.
2735 * Do not update the client->router in the function
2736 silc_server_udpate_clients_by_server if the client is on
2737 global list. We might fail to find any specific server
2738 for locally connected clients and local cell clients. They
2739 should still use the `from' and not `to' as client->router.
2740 This fixes backup router resuming protocol. Affected file
2741 silcd/server_util.c.
2743 * Decrease channel statistics count only if the channel
2744 deletion worked. Affected files are silcd/server.c and
2745 silcd/server_util.c.
2747 * Added silc_server_update_servers_by_server to update origin
2748 of all server entries. Used during backup router protocol.
2749 Affected files silcd/server_util.[ch], silcd/server.c. and
2750 silcd/backup_router.c.
2752 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2753 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2754 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2755 lib/silccrypt/silchmac.c.
2757 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2759 * Assure that router cannot reroute the same channel message
2760 to the sender. Affected file silcd/packet_receive.c.
2762 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2764 * Made better checks that the channel message is not sent
2765 to the router it came from. Affected file is
2766 silcd/packet_send.c. Fixed memory leak too.
2768 * Announce informations for incoming router connection, but
2769 only after checking if it is replaced by backup router.
2770 Affected file silcd/packet_receive.c.
2772 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Fixed the backup resuming protocol to work in multiple
2775 router environment. Affected file silcd/server_backup.c.
2777 * Route packet only to one router in the function
2778 silc_server_packet_send_to_channel. Affected file is
2779 silcd/packet_send.c.
2781 * Fixed silc_server_send_notify_dest to set the broadcast
2782 flag. Fixed the silc_server_send_notify_topic to actually
2783 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2784 Affected file silcd/packet_send.c.
2786 * Changed the SFTP Filesystem interface. Changed the
2787 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2788 the filesystem operation function. The SilcSFTPFilesystem
2789 is now a context that is allocated by all filesystem allocation
2790 functions and it already includes the operations structure
2791 and filesystem specific context. It is given as argument
2792 now to the silc_sftp_server_start. This made the interface
2793 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2794 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2796 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2798 * Changed the backup router adding and getting interfaces
2799 in the server. The router that will be replaced by the
2800 specified backup router is now sent as argument. Affected
2801 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2804 * Added silc_net_addr2bin_ne to return the binary form of
2805 the IP address in network byte order. Affected files
2806 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2808 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Check for existing server ID in silc_server_new_server
2811 and in silc_server_connect_to_router_final and remove the
2812 old entry if it exists. Affected file silcd/packet_receive.c,
2815 * Send the channel message always to only one router, either
2816 in upstream or downstream. Affected file is
2817 silcd/packet_send.c.
2819 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2821 * Wrote the definition of the backup resuming protocol to the
2822 protocol specification.
2824 * Removed one redundant channel key generation from normal
2825 server during joining procedure. Removed one redundant
2826 channel key sending from server to router during joining
2827 procedure. Affected file silcd/command.c.
2829 * Made minor bugfixes to the backup router resuming protocol.
2830 Affected file silcd/server_backup.c, server.c.
2832 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Added --disable-asm configuration option. Affected files
2835 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2838 * Implemented the backup resuming protocol that is used to
2839 resume the primary router position in the cell after the
2840 primary router comes back online. Affected files
2841 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2842 and silcd/server_util.[ch].
2844 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Sleep two (2) seconds after sending QUIT command to server.
2847 Affected file lib/silcclient/command.c.
2849 * Assure that if outgoing data buffer is pending do not force
2850 send any data. Affected file silcd/packet_send.c.
2852 * Assure that if outgoing data buffer is pending do not force
2853 send any data. Affected file lib/silcclient/client.c.
2855 * Implemented the backup router support when the primary router
2856 goes down. The servers and routers can now use the backup
2857 router as new primary router without loosing connectivity.
2859 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2862 in the server to indicate disabled entry. All data read
2863 from the connection will be ignored and no data is sent
2864 for entry that is disabled. Affected files are
2865 silcd/idlist.h, silcd/server.c.
2867 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * Created SFTP client and server test programs in the
2870 lib/silcsftp/tests directory.
2872 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Implemented memory filesystem (virtual filesystem) for
2875 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2878 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2880 * Implemented the SFTP (SSH File Transfer Protocol) to the
2881 lib/silcsftp. It includes SFTP client and SFTP server
2884 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2886 * Moved lib/silccore/silcprotocol.[ch] to the
2887 lib/silcutil library.
2889 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2890 take variable argument list pointer as argument. Affected
2891 file lib/silcutil/silcbuffmt.[ch].
2893 * Added silc_buffer_set function that is used to set data
2894 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2895 Affected file lib/silcutil/silcbuffer.h.
2897 * Changed various routines in the core library to use the new
2898 silc_buffer_set instead of allocating new buffer only for
2901 * Added 64-bit value formatting and unformatting support to the
2902 silc_buffer_[un]format routines. Affected file is
2903 lib/silcutil/silcbuffmt.[ch].
2905 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2906 to includes/bitmove.h.
2908 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Fixed channel user mode saving in client library. Affected
2911 file lib/silcclient/command[_reply].c.
2913 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Defined the file transfer to the SILC Protocol. Added
2916 new packet type SILC_PACKET_FTP and defined File Transfer
2917 Payload. The mandatory file transfer protocol is SFTP
2918 (SSH File Transfer Protocol). Affected file in addition
2919 of the internet draft is lib/silccore/silcpacket.h.
2921 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2922 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2923 is used as part of backup router protocol when the primary
2924 router of the cell is back online and wishes to resume
2925 the position as primary router.
2927 * Redefined the MAC generation keys in the protocol. The
2928 same key is not used anymore in both direction. Both
2929 direction will now use different keys for sending and
2930 receiving. This fixes a potential security flaw. This
2931 change causes incompatibilities in the protocol.
2933 * Redefined also the MAC computation from the packet.
2934 An packet sequence number is now added to the MAC
2935 computation. This prevents possible replay attacks against
2936 the protocol. This change too causes incompatibilities
2939 Added `sequence' field to the SilcPacketContext to hold
2940 the current sequence number for the packet.
2942 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2944 * Added `created' field to the SilcIDListData in the file
2945 silcd/idlist.h to indicate the time when the entry was
2948 * Added `created' field to the SilcChannelEntry too. Affected
2949 file silcd/idlist.h.
2951 * Added `creation_time' aguments to all the announcement functions
2952 in the server. If it is provided then only the entries that
2953 was created after the provided time frame are actually
2954 announced. Affected file silcd/server.[ch].
2956 * The protocol says that the Channel ID's IP address must be
2957 based on the router's IP address. Added check for this in
2958 the silc_server_new_channel when processing incoming New Channel
2959 Payload. Affected file silcd/packet_receive.c.
2961 * Print out the correct version with --version in SILC client.
2962 Affected file irssi/src/silc/core/silc-core.c.
2964 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Fixed WHOWAS command to check for completnes of the client
2967 entry always, not just when the command is coming from client.
2968 Affected file silcd/command.c.
2970 * Added new function silc_server_packet_queue_purge to purge the
2971 outgoing data queue to the network. After the function returns
2972 it is guaranteed that the outgoing packet queue is empty.
2973 Affected file silcd/packet_send.[ch].
2975 * Purge the outgoing packet queue in the rekey protocol's final
2976 callback to assure that all rekey packets go to the network
2977 before quitting the protocol. Affected file silcd/server.c.
2979 * Added silc_client_packet_queue_parse as similar function as
2980 in server to the client library. The affected file is
2981 lib/silcclient/client.c.
2983 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Splitted silcd/server.c and created silcd/server_util.[ch]
2986 for utility functions.
2988 * Added new socket flag SILC_SF_DISABLED to indicate that the
2989 connection is open but nothing can be sent to or received from
2990 the connection. Affected file lib/silcutil/silsockconn.[ch].
2991 The checking for disabled socket is checked in the low level
2992 silc_socket_write and silc_socket_read functions.
2994 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2996 * Allow only nicknames and channel names that fits into the
2997 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2999 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * When processing JOIN command reply in server check that if
3002 the channel exists in our global list we'll move it the local
3003 list. Affected file silcd/command_reply.c.
3005 * Fixed the check whether client is joined on the channel already
3006 in JOIN command. Affected file lib/silcclient/command.c.
3008 * Fixed the JOIN command reply to check whether the channel
3009 already exists. Affected file lib/silcclient/command_reply.c.
3011 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Added silc_ske_status_string to map the SKE error numbers
3014 to readable strings. The affected files are
3015 lib/silcske/silcske[_status].[ch].
3017 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Do not show the private channels on the WHOIS channel list
3020 as it is not allowed by the protocol. The affected file is
3023 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Assure that the packet length digged from the actual packet
3026 is something sensible in the silc_packet_decrypt_rest_special
3027 in lib/silccrypt/silcpacket.c.
3029 * Free and NULL the allocated pointer in silc_hmac_alloc if
3030 the HMAC allocation fails. The affected file is
3031 lib/silccrypt/silchmac.c.
3033 * Print the selected security properties to the log files in
3034 the server. Affected file silcd/protocol.c.
3036 * Add SKE's reference counter even if calling the completion
3037 callback manually. Otherwise it goes negative, although it
3038 does not cause any problems. The affected file is
3039 lib/silcske/silcske.c.
3041 * Remove the client entry with short timeout after giving the
3042 KILL command. Affected file lib/silcclient/command.c.
3044 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3045 case all found clients are already disconnected (WHOWAS would
3046 found them) in the server. Affected file silcd/command.c.
3048 * Update the last_receive (time of last data received) to be
3049 updated only when received private or channel message so that
3050 the idle time showed in WHOIS makes more sense.
3052 * Added boolean field `valid' in to the SilcClientEntry in the
3053 client library to indicate whether the entry is valid or not.
3054 This fixes the nickname change bug on channel when changing
3055 the nickname to be same than the old (like nick to Nick) the
3056 nickname formatter doesn't set the new nick anymore to Nick@host.
3057 Affected file lib/silcclient/idlist.[ch].
3059 * Now actually fixed the nickname changing on disconnection.
3060 Added new function silc_change_nick to the Irssi SILC Client.
3061 Affected file irssi/src/silc/core/client_ops.c,
3062 irssi/src/silc/core/silc-nicklist.[ch].
3064 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3066 * Check that the public key exists in the GETKEY command before
3067 trying to encode it. Affected file silcd/command.c.
3069 * Print some notifications on received public keys with GETKEY
3070 command in the Irssi SILC Client. Affected files are
3071 irssi/src/fe-common/silc/module-formats.[ch],
3072 irssi/src/silc/core/client_ops.c.
3074 * Use IDENTIFY command to resolve the server information in the
3075 GETKEY command instead of INFO command. Affected file
3076 lib/silcclient/command.c.
3078 * All command reply functions in the client library now calls
3079 the pending command reply callbacks even if an error has
3080 occurred. The server has done this a long time and now it was
3081 time to move the client library to this as well. Now all
3082 errors can be delivered back to the pending command reply
3083 callbacks if necessary. Affected files are
3084 lib/silcclient/command[_reply].[ch].
3086 * Change the nickname on disconnection back to the username
3087 because in reconnect the server will enforce it to it anyway.
3088 Affected file irssi/src/silc/core/silc-servers.c.
3090 * Fixed a config file parsing bug in the Irssi SILC client.
3091 Affected file irssi/src/silc/core/clientconfig.c.
3093 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3095 * When printing the channel mode on JOIN, verify that the
3096 channel key and channel's HMAC are valid. Affected file
3097 irssi/src/silc/core/client_ops.c.
3099 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3102 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3103 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3105 * Removed channel key rekey task deleting from the function
3106 silc_server_save_channel_key. Affected file silcd/server.c.
3107 Added explicit timeout task context instead that is used to
3108 delete the task if we are registering a new task before the
3109 new task has elapsed.
3111 * When channel key rekey occurs the client library now saves
3112 the old channel key for a short period of time (10 seconds) and
3113 is able to use it in case some is still sending channel
3114 messages encrypted with the old key after the rekey. Affected
3115 file lib/silcclient/[idlist.h|client_channel.c].
3117 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3119 * Added check to the silc_server_new_id_real to not accept
3120 new ID if it is the sender's own ID. Affected file is
3121 silcd/packet_receive.c.
3123 * Assure that we do not announce ourself or the one we've
3124 sending our announcements when we're router and are announcing
3125 servers to our primary router. Affected file silcd/server.c.
3127 * Fixed silc_server_command_identify_check_client to assemble
3128 correct WHOIS packet. It send corrupted WHOIS packet and
3129 caused problem with router to router connections. Affected
3130 file silcd/command.c.
3132 Fixed also silc_server_command_whois_check the same way
3133 as for the IDENTIFY command.
3135 * Added new SilcIDListStatus to the server in the SilcIDListData
3136 structure. The status now includes the current status of
3137 the entry (like registered, resolved etc.). Affected file
3138 silcd/idlist.[ch]. Defined a bunch of different status types
3139 as well. This replaced the old boolean registered field as well.
3141 Added resolve_cmd_ident field to the SilcClientEntry structure
3142 too so that if the entry is for example being resolved so
3143 another command may attach to the same pending command reply
3144 without requiring to resolve the same entry again. This concept
3145 should optimize the WHOIS and the IDENTIFY resolving under
3146 heavy load by taking away unnecessary resolving for entries
3147 that are being resolved already.
3149 Added support for adding multiple pending commands for one
3150 command idenfier. Affected file silcd/command[_reply].[ch].
3152 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3153 before deleting the data. Otherwise the hash table will have
3154 freed data in comparison functions. Affected file is
3155 silcd/command_reply.c.
3157 * Fixed silc_idlist_replace_client_id to add the new entry to
3158 the cache with NULL nickname. Otherwise there will be invalid
3159 memory as the nickname after the nickname is freed. Affected
3160 file silcd/packet_receive.c.
3162 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3163 saved into wrong slots because the previous number of entries
3164 was not taken into account. Affected file silcd/idlist.c.
3165 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3167 * If we are router and we receive JOIN notify to a channel that
3168 does not have any users then notified client is marked as the
3169 channel founder, as it is it. The affected file is
3170 silcd/packet_receive.c
3172 * Added to the extended hash table API's table_del_*ext functions
3173 the destructor as argument too, so that the caller can decide
3174 which destructor to use or whether to use destructor at all.
3175 Affected file lib/silcutil/silchashtable.[ch].
3177 * Fixed ID Cache purging. It actually deleted the entries from
3178 the hash table after the data was freed. The hash table ended
3179 up comparing freed memory. The affected file is
3180 lib/silccore/silcidcache.c.
3182 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Fixed Irssi SILC client's KILL command's HELP syntax.
3186 * The USERS command now resolves the detailed user information
3187 if the userinfo field is missing. Affected file is
3188 lib/silcclient/command_reply.c.
3190 * Do not print error in silc_file_read if the read file does
3191 not exist. Just silently return NULL. Affected file is
3192 lib/silcutil/silcutil.c.
3194 * Fixed the silc_log_output to not wine about NULL filename
3195 and to not create some bogus " " filename. Affected file is
3196 lib/silcutil/silclog.c.
3198 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3200 * Fixed various printing bugs on the user interface in the
3201 Irssi SILC Client. Minor changes that were forgotten from
3204 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Fixed the configure.in.pre and the compilation and distribution
3207 environment to support the new autoconf 2.52. That version is
3208 now required to compile the CVS trunk.
3210 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3213 to generally parse user@fqdn format strings. Affected file
3214 lib/silcutil/silcutil.c.
3216 * Added nickname_format and nickname_force_format fields to the
3217 SilcClientParams structure. The first one defines the format
3218 for the nicknames that the library will enforce if the receives
3219 multiple same nicknames. The second one is boolean value and
3220 can be used to force the library to always enforce the format
3221 to the nicknames regardles whether there are multiple nicknames
3222 or not. This configurable formatting was employed to flexibly
3223 support accessing multiple nicknames from the user interface.
3224 The userinterface can now set the nicknames to what ever format
3225 they prefer. Affected file lib/silcclient/silcapi.h.
3227 Added function silc_client_nickname_format to the file
3228 lib/silcclient/idlist.c. It performs the nickname formatting.
3230 Added new field `hostname´ to the SilcClientEntry context.
3231 It holds the hostname of the client. Affected file is
3232 lib/silcclient/idlist.h.
3234 * Irssi SILC Client sets the nicknames in nick@hostn format.
3235 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3236 irssi/src/silc/core/silc-core.c.
3238 The WHOIS printing now also shows both the real nickname and
3239 the formatted nickname so that user knows how to access the
3240 user if there are multiple same nicknames cached. Affected
3241 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3242 printing formatting too to take the hostname now as a separate
3243 argument. The Affected file is
3244 irssi/src/fe-common/silc/modules-formats.[ch].
3246 * Changed the silc_client_get_clients_local to accept the formatted
3247 nickname as argument. It accepts the real nickname too but the
3248 formatted nickname can be used to find the true entry from
3249 multiple entries. Affected file lib/silcclient/silcapi.h and
3250 lib/silcclient/idlist.c.
3252 * Added nickname_format_parse field to the SilcClientParams.
3253 It is a callback function provided by the application to parse
3254 the nickname out of the formatted nickname string. The library
3255 calls it to get the nickname from the formatted string. Since
3256 the application generally knows better the format of the nickname
3257 string it parses it instead of the library, even though library
3258 encodes the formatted string. If the callback function is not
3259 provided then the library will use the string as is. The
3260 affected file is lib/silcclient/silcapi.h.
3262 * All the nickname strings passed to the client library in
3263 commands are now expected to be formatted nickname strings.
3264 If the command does not support the formatted nickname string
3265 it will assume that the sent string is the actual nickname.
3266 Affected file lib/silcclient/command.c.
3268 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Added public key authentication support to OPER and SILCOPER
3271 commands in the client library. Affected file is
3272 lib/silcclient/command.c.
3274 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Changed the get_auth_methdod client operation to be asynchronous.
3277 It can be async if the application resolves the authentication
3278 method from the server during the negotiation. Added new
3279 SilcGetAuthMeth completion callback that the application will
3280 call after resolving the authentication method.
3282 Added function silc_client_request_authentication_method that
3283 the application can use to resolve the authentication method
3284 from the server. Added also SilcConnectionAuthRequest callback
3285 that the library will call after the server has replied. The
3286 application can call this function if it does not know the
3287 current authentication method.
3289 Affected files are lib/silcclient/client.c and
3290 lib/silcclient/silcapi.h.
3292 * The Irssi SILC client now automatically resolves the authentication
3293 method incase any configuration information is not present (and
3294 currently there never is). The affected file is
3295 irssi/src/silc/core/client_ops.c.
3297 * Fixed public key authentication from the client library.
3298 Affected file lib/silcclient/protocol.c. Changed also the
3299 protocol specification about the public key authentication in
3300 the connection authentication protocol. The actual data to be
3301 signed is now computed with a hash function before signing.
3303 * Fixed the public key authentication from the server as well.
3304 Affected file silcd/protocol.c.
3306 * Removed the mlock()'s from the memory allocation routines.
3307 Affected file lib/silcutil/silcmemory.c. The ./configure does
3308 not check anymore for the mlock(). Affected file is
3311 * Fixed USERS command in server to allow the execution of the
3312 command for private and secret channels if the client sending
3313 the command is on the channel. Affected file silcd/command.c.
3315 * Fixed silc_client_get_clients_local to return the clients
3316 count correctly. It could return wrong value. Affected file
3317 lib/silcclient/idlist.c.
3319 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3322 types. The assembler optimizations seemed not to like 64-bit
3323 data types. The assmebler optimizations thus are now enabled
3324 also for BSD systems as opposed to only enable them for Linux.
3326 * Do not check for threads at all on BSD systems. Affected
3327 file configure.in.pre.
3329 * Removed -n and -h options from the Irssi SILC Client since
3330 they are not used in silc.
3332 * Fixed the prime generation to assure that the first digit
3333 of the generated random number is not zero since our conversion
3334 routines does not like number strings that starts with zero
3335 digit. If zero digit is seen the random number is regenerated.
3336 This caused some corrupted RSA keys when the zero first digit
3337 was met. Affected file lib/silcmath/silcprimegen.c.
3339 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3341 * Fixed WIN32 configuration in the ./configure script.
3342 Fixed to include xti.h on environments that has it.
3343 Patches by Carsten Ilchmann and andrew.
3345 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Changed the silc_id_create_client_id to be collision
3348 resistant. It is now assured that there cannot be created
3349 two same client ID's. I suspect that some weird bugs in
3350 the server were actually caused by duplicate Client IDs.
3351 Affected file silcd/serverid.[ch]. A router receiving
3352 new ID now also assures and informs the sending server
3353 if the ID caused collision.
3355 * Changed the silc_id_create_channel_id to also assure that
3356 there are no collisions.
3358 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Statement about ignoring the Mutual Authentication flag when
3361 performing rekey with PFS was a bit misleading. It is ignored
3362 if it was set in the initial negotiation, it cannot be even
3363 set in the rekey. Fixed in the ke-auth draft. Started the
3364 new versions of the protocol drafts in the doc/.
3366 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Fixed a bug in silc_client_command_identify_save when saving
3369 new channel information. The channel name was no duplicated
3370 and caused crash on exit. Affected file is
3371 lib/silcclient/command_reply.c.
3373 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Fixed the getkey command handling in the server. Send just
3376 empty OK reply to the sender if the key could not be fetched
3377 (but everything else was ok, like the key just was not available).
3378 Changed the public key parameter to optional in the protocol
3379 specs so that empty OK reply can be sent. Affected file
3382 Added a message to Irssi SILC client to tell to user if the
3383 server did not return a public key.
3385 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Fixed a channel key regeneration bug. It registered new
3388 timeout tasks exponentially until all system resources were
3389 used. Affected file silcd/server.c.
3391 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3393 * Added the SILC Document generator to the scripts/silcdoc.
3394 It can be used to generate the Toolkit Reference Manual out
3395 of the source tree. Internally it will also use the RoboDoc
3396 generator now imported in util/robodoc.
3398 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Added couple of return's in rekey protocol if error orccurred
3401 during the protocol. The execution must be terminated.
3402 Affected file silcd/protocol.c. Also, terminate the protocol
3403 always with timeout.
3405 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3407 * The client's Client ID was created initally from the wrong
3408 nickname (it could have been in format nick@host) in the
3409 silc_server_new_client. Affected file silcd/packet_receive.c
3411 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3413 * Added some SILC_LOG_ERROR's to various error conditions
3414 if client could not be added to ID cache. Affected files
3415 silcd/packet_receive.c and silcd/server.c.
3417 * When client's sock->user_data is freed, NULL also the
3418 client->router and client->connection pointers. Added check
3419 for these pointers being NULL to various places around the
3420 code. Affected file silcd/server.c.
3422 * Added client->data.registered == TRUE checks to various
3423 places around the code to assure that unregistered client's
3424 are not handled when it is not allowed. Affected file
3427 * Added `bool registered' fields to all
3428 silc_idlist_[server|client]_get_* routines to indicate whether
3429 the fetched client needs to be registered or not. Affected
3430 file silcd/idlist.[ch].
3432 * Add your own entry as registered to the ID cache in the
3433 server. Affected file server.c.
3435 * Fixed a bug in silc_server_new_server. The SilcServer was
3436 set as the new server's context instead of SilcServerEntry.
3437 This naturally caused some weird bugs.
3439 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3441 * Do not delete the channel rekey task when adding it
3442 for in silc_server_create_channel_key.
3444 * Changed the silc_server_create_channel_key to return
3445 TRUE or FALSE to indicate the success of the channel key
3448 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Fixed MSVC++ project files and added missing files to
3451 Makefiles under win32/.
3453 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3455 * Do not add TCP_NODELAY flag if the operating system
3456 does not have it defined. Affected files are
3457 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3459 * Fixed buffer overflow from Irssi SILC Client. Affected
3460 file irssi/src/fe-common/core/themes.c.
3462 * Fixed double free in client library in the file
3463 lib/silcclient/client.c when disconnecting from server.
3465 * Applied double free patch from cras to Irssi SILC client.
3466 Affected files irssi/src/core/[modules/expandos].c
3468 * Fixed the disconnection handling to Irssi SILC Client.
3469 The application must call silc_client_close_connection
3470 in ops->connect client operation in case of failure of
3471 the connection. Affected file is
3472 irssi/src/silc/core/client_ops.c.
3474 * Do not set sock->protocol to NULL in the function
3475 silc_client_close_connection after executing the protocol's
3476 final callback since the sock might not be valid anymore.
3477 Affected file lib/silcclient/client.c.
3479 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Do not enable SILC_THREADS if the linking with libpthread
3482 did not happen. Affected file configure.in.pre.
3484 * Added notion to protocol specification that server must
3485 verify the sent authentication payload with CMODE when
3486 setting the channel founder key. Implemented it to the
3487 server. Affected file silcd/command.c.
3489 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Added _EXTRA_DIST SILC distribution variable to the
3492 distributions file. It is used to conditionally add extra
3493 files or directories to the specific distribution. Affected
3494 files ./prepare, Makefile.am.pre and distributions.
3496 Removed the `_' from the start of the distribution names.
3499 * Added README.WIN32 for instructions to compile the Toolkit
3502 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Fixed a double free in disconnection in the server. Affected
3505 file is silcd/server.c.
3507 * Fixed the lib/silcske/groups.c to work now also with GMP
3508 MP library. The string conversion did not work when using
3509 specific base and the base is indicated in the string as well.
3511 * Created win32/ directory which now includes MSVC++ specific
3512 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3513 It will appear only in the toolkit distribution
3515 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * Changed the key material distribution function in case when
3518 the hash output is too short. The data is now concatenated
3519 a bit differently than it used to. Made the change to the
3520 SKE protocol specification.
3522 * Added better GMP detection to configure.in.pre. A patch
3525 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Fixed a minor bug in SKE that might cause some problem on
3528 some platforms. Affected file lib/silcske/silcske.c.
3530 * Added the cookie checking for initiator in the SKE. It checks
3531 that the responder returns the sent cookie unmodified. The
3532 affected file is lib/silcske/silcske.c. Added new SKE
3533 error type INVALID_COOKIE that can be sent during the
3534 negotiation. Fixed some memory leaks as well.
3536 * Added the "invalid cookie" error message to Irssi SILC client's
3539 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Added `task_max' field to the SilcClientParams to indicate
3542 the maximum tasks the scheduler can handle. If set to zero,
3543 default values are used. Affected file lib/silcclient/silcapi.h.
3545 * Fixed memory leaks in silc_client_close_connection. Affected
3546 file lib/silcclient/client.c.
3548 * Added silc_client_del_client_entry to client library to free
3549 all memory of given client entry. Affected file is
3550 lib/silcclient/idlist.[ch].
3552 * Added new functions silc_client_del_channel and
3553 silc_client_del_server to delete channel and server entries.
3554 Affected file lib/silcclient/[silcapi.h/idlist.c].
3556 * Removed silc_client_del_client_by_id from silcapi.h.
3558 * Fixed the INFO command to return the server's own info
3559 correctly when querying by Server ID. Affected file is
3562 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Removed the non-blocking settings in WIN32 code in the
3565 silc_sock_[read/write] and added SleepEx instead. Affected
3566 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3567 of input data is now checked with FIONREAD and ioctlsocket.
3569 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Call silc_schedule_task_del_by_context in the
3572 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3573 Affected file lib/silccore/silcprotocol.c.
3575 * Call silc_protocol_cancel for active protocols in the
3576 silc_server_close_connection if the funtion
3577 silc_server_free_sock_user_data has not been called.
3578 Affected file silcd/server.c.
3580 * Generic tasks cannot be deleted using the del_by_fd
3581 task deleting function since generic tasks does not match
3582 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3584 * Added a notion to SILCOPER help file that the SILCOPER works
3585 only on router server, not on normal server.
3587 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3589 * Added for WIN32 support for the new scheduler as well.
3590 Affected file lib/silcutil/win32/silcwin32schedule.c.
3592 * Fixed the SHA1 implementation to work on various platforms.
3594 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3597 API. It is part of the scheduler now. Everything else is
3598 as previously but some functions has changed their names.
3599 Checkout the lib/silcutil/silcschedule.h for the interface.
3600 Updated all applications to use the new interface. Affected
3601 files are lib/silcutil/silcschedule.[ch].
3603 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Found a bug in the SKE implementation. The HASH value,
3606 specified by the protocol, was not computed correctly. The
3607 public key of the responder was not added to the computation
3608 even though it is mandatory. Affected file lib/silcske/silcske.c.
3609 This unfortunately causes incompatibilities with older
3610 clients and servers.
3612 * Added WIN32 specific network init and uninit functions:
3613 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3614 the Winsock2. Affected file lib/silcutil/silcnet.h and
3615 lib/silcutil/win32/silcwin32net.c.
3617 * Set the socket always to nonblocking mode on WIN32 after
3618 reading data or writing data. Affected file is
3619 lib/silcutil/win32/silcwin32sockconn.c.
3621 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Fixed various compilation problems under WIN32. Affected
3624 files lib/silcutil/win32/silcwin32thread.c and
3625 lib/silcutil/win32/silcwin32schedule.c.
3627 * Removed all _internal.h #includes from public header
3628 files. Internal headers must never be included from
3631 Removed also the lib/silcske/payload_internal.h file.
3633 * All include files that may be needed (public and some others
3634 included by the public headers) by application developers are
3635 now copied to the ./includes directory. It does not copy any
3636 internal headers. Affected file Makefile.defines.pre and all
3637 Makefile.am's under lib/ and subdirs.
3639 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Do not change the ~/.silc directory's permissions automatically.
3642 Affected file irssi/src/silc/core/clientutil.c.
3644 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Do not cancel the protocol in silc_server_close_connection
3647 it might cause recursion. Now cancelled in the function
3648 silc_server_free_sock_user_data. Affected file silcd/server.c.
3650 * Fixed the silc_server_remove_clients_by_server to regenerate
3651 the channel keys correctly finally. Added also new function
3652 silc_server_remove_clients_channels to actually do it.
3653 Affected file silcd/server.c.
3655 * Fixed the silc_server_new_channel to not crash by giving
3656 wrong router to the new channel. Affected file is
3657 silcd/packet_receive.c.
3659 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3661 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3662 which is given as argument to the silc_client_alloc now.
3663 It can be used to configure the client and set various parameters
3664 that affect the function of the client.
3666 * The USERS command in server did not check whether the channel
3667 is private or secret. Affected file silcd/command.c.
3669 * Added new argument to the USERS command in protocol specification.
3670 The USERS command now can take the channel name as argument
3671 as well. Added support for this in client and server and
3672 updated the protocol specs.
3674 * Completed the GETKEY command in client. It can be now used
3675 to fetch also servers public key not only some clients.
3676 Affected files lib/silcclient/command[_reply].c.
3678 * Added silc_client_get_server to return server entry by the
3679 server name. Affected files lib/silcclient/silcapi.h and
3682 * Redefined the IDENTIFY command in protocol specification to be
3683 more generic. It now can be used to query information about
3684 any entity in the SILC Network, including clients, servers and
3685 channels. The query may be based either the entity's name
3686 or the ID. Added support for this in both client and server.
3688 Affected files silcd/command.c and lib/silcclient/command.c
3689 and command_reply.c.
3691 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3692 the _from_client and _from_server functions. Affected file
3695 * Added silc_client_get_channel_by_id_resolve to the file
3696 lib/silcclient/silcapi.h to resolve channel information by
3697 its ID. Added also silc_client_get_channel_by_id that
3698 does not resolve it from the server.
3700 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3702 * Added SilcServerEntry context into the client library
3703 to represent one server. The INFO command now allocates
3704 these to save the resolved server info. For now on the
3705 client library will also keep information about servers,
3706 connected and resolved with INFO.
3708 The INFO command now allocates the SilcServerEntry context
3709 and saves the server info there. The COMMAND_REPLY in
3710 the INFO now returns the parameters to application in
3711 same order as defined in the protocol specification.
3713 The entries are cached in the client->server_cache.
3715 * The INFO command is now issued after received the Client ID
3716 from the server. Affected file lib/silcclient/client.c.
3718 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3719 to the application as the mode changer might be server.
3720 It is guaranteed that NULL is not returned anymore to the
3721 application. Affected file lib/silcclient/client_notify.c.
3723 The ID Type is now also passed to the application so that
3724 it can check whether the returned entry is SilcClientEntry
3727 Added new function silc_client_get_server_by_id to return
3728 the server entry by ID. Affected files are the
3729 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3731 * Do not create the channel in the Irssi SILC Client when issuing
3732 the JOIN command but when received the sucessful JOIN command
3733 reply. Otherwise the channel might get created even though we
3734 could not join it. The Affected file is
3735 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3737 * Fixed a channel joining bug in router. The router must also
3738 check the channel modes, invite and ban lists etc. when serving
3739 the JOIN command sent by normal server. Affected file is
3740 silcd/command.c. The router now resolves the client's
3741 information from the server who sent the JOIN command if it
3742 does not know it, and processes the JOIN command only after
3745 * Changed the SilcCommandCb to take new argument; void *context2.
3746 Affected file lib/silccore/silccommand.h
3748 The second argument in the command callbacks in the server now
3749 includes the SilcServerCommandReplyContext if the command was
3750 called as pending command callback from the command reply.
3751 Otherwise it is NULL. When called as pending the status of the
3752 command reply will be checked and if it was erronous the
3753 error will be sent to the original sender of the command.
3754 This way the client always receives the error messages even
3755 though the server was actually the one who received the error
3756 when it resent the command to router, for example. Affected
3757 files silcd/command[_reply].[ch].
3759 * Fixed sending WHOWAS command's error message to client if
3760 the requested client could not be found. It was missing.
3763 * Changed the CMODE and CUMODE commands reply arguments in the
3764 protocol specification. The Channel ID is now sent in both
3765 of the commands to identify the channel. Implemented this
3766 new feature to the client and server. Affected files
3767 lib/silcclient/command_reply.c and silcd/command.c.
3769 * Made better checks for invite and ban lists in the JOIN
3770 command in server. Affected file silcd/command.c.
3772 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3774 * The server now performs the incoming host IP/DNS lookup
3775 using the silc_socket_host_lookup and thus does not block
3776 the server anymore. Affected file silcd/server.c.
3778 * Completed the multi-thread support for SILC Scheduler in
3779 the lib/silcutil/silcschedule.c.
3781 * Fixed the configure.in.pre to detect the pthread correctly
3784 * Fixed a deadlock in silc_task_queue_wakeup in the file
3785 lib/silcutil/silctask.c.
3787 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3789 * Added new function silc_schedule_wakeup that is used in
3790 multi-threaded environment to wakeup the main thread's
3791 schduler. It needs to be used when a thread adds a new task
3792 or removes a task from task queues. After waking up, the
3793 scheduler will detect the task queue changes. If threads
3794 support is not compiled in this function has no effect.
3795 Implemented the wakeup mechanism to both Unix and WIN32
3796 systems. Affected files are lib/silcutil/silcschedule.[ch],
3797 lib/silcutil/unix/silcunixschedule.c and the
3798 lib/silcutil/win32/silcwin32schedule.c.
3800 * Added new function silc_task_queue_wakeup to wakeup the
3801 scheduler by the specified task queue. Affected file
3802 lib/silcutil/silctask.[ch].
3804 * The silc_socket_host_lookup_start now wakes up the scheduler
3805 after adding the timeout task. Affected file is
3806 lib/silcutil/silcsockconn.c.
3808 * The silc_socket_host_lookup is synchronous now if the threads
3809 support is not compiled in. However, the callback is still
3810 called asyncronously through the scheduler, anyway. Affected
3811 file lib/silcutil/silcsockconn.c.
3813 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Added new function silc_socket_host_lookup to perform
3816 asynchronous IP and FQDN lookups for the socket connection.
3817 Affected files lib/silcutil/silcsockconn.[ch].
3819 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3822 that may or may not compile the mutex support in.
3824 Changed the silc_mutex_alloc interface. It allocates the
3825 mutex now to the sent pointer and returns TRUE or FALSE.
3827 Affected file lib/silcutil/silcmutex.h.
3829 * Wrote the SILC Task Queue interface to support multi-threads.
3830 Affected file lib/silcutil/silctask.[ch].
3832 * Wrote the SILC Scheduler to support multi-threads. Affected
3833 file lib/silcutil/silcschedule.c.
3835 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3837 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3838 in lib/silcutil/win32/.
3840 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3842 * Defined SILC Mutex API and SILC Thread API and implemented
3843 them for Unix. Affected files are
3844 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3845 lib/silcutil/unix/silcunixmutex.c and
3846 lib/silcutil/unix/silcunixthread.c.
3848 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Fixed the silc_server_remove_clients_by_server's channel
3851 key re-generation. The hash table handling was incorrect
3852 and would not work with many channels. Affected file is
3855 * Fixed some memory leaks around the server code.
3857 * Rewrote the silc_server_get_users_on_channel to support IPv6
3858 based Client ID's. Affected file silcd/server.c.
3860 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3861 specification. However, a separate document must be written
3862 to define the detailed signing procedure and the payload
3863 associated with the flag. Defined the flag to the
3864 lib/silccore/silcchannel.h as well.
3866 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * Changed the dynamic tables to static size tables in the
3869 lib/silccrypt/silchmac.c.
3871 * Removed GCC dependencies from the code. A patch by cras.
3873 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3875 * Do not show the error "Error receiving packet bla bla"
3876 in server if it really was not an error (-2 means that reading
3877 is pending). Affected file silcd/server.c.
3879 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Fixed a possible crash in silc_server_remove_clients_by_server
3882 in silcd/server.c. Fixed there also some memory leaks.
3884 * Fixed the silc_idlist_replace_client_id. It could replace
3885 wrong key in the hash table. Affected file silcd/idlist.c.
3887 * Do not check whether there are global users on the channel
3888 if the channel->global_users is FALSE. Affected functions
3889 silc_server_remove_from_one_channel and
3890 silc_server_remove_from_channels in silcd/server.c. Also,
3891 do not check if the removed client is local as we can be
3892 sure that global client was not removed from the channel
3893 and checking for global users is not needed.
3895 * The silc_server_remove_clients_by_server now re-generates
3896 the channel keys correctly for those channels that had
3897 clients removed from them. Affected file silcd/server.c.
3899 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Found the reason of random crashes in the server. We weren't
3902 ignoring the SIGPIPE signal (which can be sent in write())
3903 and it crashed the server. Affected file silcd/silcd.c.
3905 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3907 * Assure that sock->user_data is not NULL in the function
3908 silc_server_packet_send in silcd/packet_send.c.
3910 * Disconnect the remote connection if it could not be added
3911 to any ID lists in the server. The affected file is
3914 * Check in silc_server_packet_send[_real/dest] that the
3915 socket is not disconnecting and ignore the data if it is.
3916 Affected file silcd/packet_send.c.
3918 * Define inline to __inline on native WIN32 compilation.
3919 Affected file includes/silcwin32.h.
3921 * Added some explicit type casts for inline code since MSVC
3922 require them. Affected files lib/silcutil/silcbuffer.h,
3923 lib/trq/silcdlist.h and lib/trq/silclist.h.
3925 * Print warning in log files from now on if the packet
3926 decryption fails. Affected file silcd/server.c.
3928 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Changed the `say' client operation's interface to accept
3931 new `type' argument to indicate the type of the message sent
3932 by the library. The application may filter the library's
3933 messages according the type. The affected file is the
3934 lib/silcclient/silcapi.h.
3936 * Added two new functions to lib/silcclient/silcapi.h:
3937 silc_client_del_client and silc_client_del_client_by_id.
3938 Affected file lib/silcclient/idlist.c.
3940 * Moved the clientincludes.h from includes/ to silc/ and
3941 serverincludes.h from includes/ to silcd/.
3943 * The modes for the CMODE and CUMODE are now passed as
3944 uint32 for application with COMMAND_REPLY. The affected
3945 file is lib/silcclient/command_reply.c.
3947 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * /WHOIS without arguments shows client's own information.
3950 Affected file lib/silcclient/command.c.
3952 * Changed PING to not accept any arguments. The specs
3953 says that client can ping only the connected server so
3954 requiring an argument is not needed. Affected file is
3955 lib/silcclient/command.c.
3957 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3959 * Fixed a fatal bug in private message sending and reception
3960 encryption and decryption when using private message keys.
3961 The implementation was incorrect and did not follow the
3962 specification. It causd that some of the message were
3963 lost since it did not use the sending and receiving keys
3964 as the protocol suggests. This has been fixed and will cause
3965 incompatibilities with older clients when sending private
3966 message encrypted with private message keys. Affected files
3967 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3968 and various other in Irssi SILC Client.
3970 Added `responder' boolean argument to the functions
3971 silc_client_add_private_message_key[_ske] to indicate when
3972 the key is added as responder or initiator of the key
3975 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3977 * Removed the silc_ske_check_version function and created
3978 a SilcSKECheckVersion callback. Added also a function
3979 silc_ske_set_callbacks that is now used to set all SKE
3980 callbacks. The callback functions are not given to
3981 the SKE functions anymore, but this function is used to
3984 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3986 * Added `silc_version' argument to the silc_client_alloc
3987 to define the version of the application for the library.
3988 The library will use the version string to compare it
3989 against the remote host's (usually a server) version
3990 string. Affected file lib/silcclient/silcapi.h
3992 * Added the KE protocol context to Key Agreement context
3993 in client library so that we can abort the SKE if it
3994 is in process when we get timeout. Affected file is
3995 lib/silcclient/client_keyagr.c.
3997 * Do not resolve the client ID forever if it returns in the
3998 first time that such client does not exist. This was done
3999 for example with private message. Affected file is
4000 lib/silcclient/client_prvmsg.c.
4002 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4004 * Do not add regex.h for WIN32. The affected file
4005 includes/silcincludes.h.
4007 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4008 not work yet 100%. It generates the DLL's automatically
4009 when compiling with --with-win32 under cygwin.
4011 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * lib/contrib/regex.c is not compiled on WIN32.
4015 * Added silc_net_get_socket_opt function to the
4016 lib/silcutil/silcnet.h.
4018 * Added includes/silcwin32.h for WIN32 specific includes
4021 * Do not use ptime structure or any of the posix process
4022 functions on WIN32 in lib/silccrypt/silrng.c.
4024 * Added silc_gettimeofday to provide generic function
4025 for struct timeval on all platforms. Added the function
4026 to lib/silcutil/silcutil.h.
4028 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4030 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4031 library as they clearly belong there. As a plus side we
4032 can make the actual socket connection routines platform
4035 Added also new generic function silc_socket_read and
4036 silc_socket_write (that used to be silc_packet_[read/write].
4037 The implementation of these are platform specific.
4039 * Added WIN32 specific routines of silc_socket_[read/write]
4040 to lib/silcutil/win32/silcwin32sockconn.c.
4042 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4044 * Added preliminary support for native WIN32 compilation under
4045 cygwin (using the -mno-cygwin option for GCC) to the
4046 ./configure.in.pre. The --with-win32 now prepares the
4047 compilation for native WIN32.
4049 * Rewrote the SILC Scheduler interface in the file
4050 lib/silcutil/silcschedule.h. The scheduler is now context
4051 based and does not have anymore any global static scheduler.
4052 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4053 and created lib/silcutil/win32 directory for WIN32 based
4056 * Added Unix specific network routines to the
4057 lib/silcutil/unix/silcunixnet.c and the old
4058 lib/silcutil/silcnet.c includes now only generic routines.
4060 Added WIN32 specific network routines to the
4061 lib/silcutil/win32/silcwin32net.c.
4063 * Added Unix specific utility functions from the
4064 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4066 * Added WIN32 SILC Scheduler to the file
4067 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4070 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4072 * Do not handle JOIN notify in the server if the target client
4073 is not registered (idata->registered == FALSE). The affected
4074 file is silcd/packet_receive.c.
4076 * Update the nickrec->founder in event_cumode in the Irssi SILC
4077 client. Affected file irssi/src/silc/core/silc-channels.c.
4079 * Fixed the CUMODE_CHANGE notify handling in the server when
4080 server and router are announcing their clients on channels.
4081 Now the mode changes are saved and notified correctly. The
4082 affected file is /silcd/packet_receive.c.
4084 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4085 They really did not replace the cache entry in the ID Cache.
4086 Now they do that. Affected file silcd/idlist.c.
4088 * Fixed the KICK notify handling in the Irssi SILC client to
4089 update the channel records so that the kicked client does not
4090 appear to be on the channel. The affected file is
4091 irssi/src/silc/core/silc-channels.c.
4093 * Always update the conn->current_channel when executing command
4094 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4096 * Fixed the KILL notify handling in Irssi SILC client to remove
4097 the killed client on all channels.
4099 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4101 * Fixed the silc_parse_command_line to remove extra spaces
4102 from the start and end of the arguments. Affected file is
4103 lib/silcutil/silcutil.c.
4105 * Cancel and free any active protocol in the function
4106 silc_server_close_connection. Affected file silcd/server.c.
4108 * Cancel and free any active protocol in the function
4109 silc_client_close_connction. Affected file is
4110 lib/silcclient/client.c.
4112 * Do not execute the KILL command for clients that are in
4113 history (ie. they are not in the network). Affected file is
4116 * Fixed KILL notify handling, client does not crash anymore.
4117 Affected file irssi/src/silc/core/silc-channels.c.
4119 * Reduced the default packet buffer size from 2048 to 1024 in
4120 lib/silccore/silcpacket.c.
4122 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4123 counter to the SKE context that is incresed when the SKE library
4124 performs async operation outside the library. If the outside
4125 process frees the SKE context and FREED status will be set
4126 and the library will detect after the sync operation that the
4127 libary is freed. The affected files are
4128 lib/silcske/silcske[_status].[ch].
4130 * Resolve the client entry information in the function
4131 silc_client_channel_message to assure that NULL pointer is not
4132 passed as client entry to the application. */
4134 * Fixed the task timeout calculation to assure that there is
4135 never negative timeouts. The affected file is
4136 lib/silcutil/silcschedule.c.
4138 * Fixed the channel user mode notification sending in server.
4139 It was sent point-to-point to the router (or to server by router)
4140 but it needs to be destined to a channel. The routines now
4141 supports sending the channel user mode notifys to the channels
4142 when announcing clients and channels. Affected files are
4143 silcd/server.c and silcd/packet_receive.c.
4145 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4146 It did not actually replace the old channel entry in the cache.
4147 Affected file lib/silcclient/client_notify.c.
4149 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Fixed a possible crash in silc_packet_send_prepare. It now
4152 assures always that there is enough space in the buffer and
4153 at the tail area of the buffer (for MAC).
4155 Fixed the inbound buffer reallocation in silc_packet_read.
4156 It was old code and did not handle the reallocation correctly.
4159 The affected file is lib/silccore/silcpacket.c.
4161 * Fixed buffer overflow in silc_parse_nickname in the file
4162 lib/silcutil/silcutil.c.
4164 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * make install generates new server keys only if there is not
4169 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4172 Added check that if the NOREPLY is set then we will not send
4173 the away message. This avoids infinite loop of away messages
4174 if both clients are away. The affected file is
4175 lib/silcclient/client_prvmsg.c.
4177 * Fixed client crash if /NICK was given without arguments.
4178 Affected file lib/silcclient/command.c.
4180 * Server does not send the invite list in INVITE command back
4181 to the client if the list was not altered. Added this notion
4182 to the protocol spec as well. Affected file silcd/command.c.
4184 Fixed possible crash in INVITE command by checking the
4185 value of silc_server_get_client_route command.
4187 * Fixed the INVITE notify type handling. The arguments are now
4188 taken in correct order and client does not crash. The affected
4189 file is irssi/src/silc/core/silc-channels.c.
4191 Removed the "Inviting xxx to channel" message from the
4192 client library away and let the application handle it.
4193 Affected file lib/silcclient/command.c. Added that message
4194 to Irssi SILC client's message formats.
4196 * Fixed CMODE command crash in client. It now checks the
4197 amount of arguments correctly and does not crash. The affected
4198 file is lib/silcclient/command.c.
4200 * Do not create new channel automatically in silc_channels_join
4201 but check whether the channel by that name already exists.
4202 Affected file irssi/silc/core/silc-channels.c.
4204 * Do not send the SERVER_SIGNOFF to router if the disconnected
4205 entity was the router. Affected file silcd/server.c.
4207 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4208 SILC client as it was missing from there.
4210 Added the handling of the KICK notify to the Irssi SILC client
4211 as it was missing. Added "you have been kicked" message to
4212 Irssi SILC client's message modules formats.
4214 Added the handing of the KILL notify to the Irssi SILC client
4215 as it was missing. Added the kill message module formats
4218 The affected file is irssi/src/silc/core/silc-channels.c.
4220 * The router did not save the channel mode the server announced.
4221 Affected file silcd/packet_receive.c.
4223 * Fixed a possible crash in INFO command in server. If the
4224 server did not provide the server info it crashed. Affected
4225 file silcd/command.c.
4227 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4229 * Fixed the GETKEY command in the server to check also the
4230 global list. Otherwise the GETKEY would not work correctly
4231 in normal SILC server. Affected file silcd/command.c.
4233 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4235 * Fixed GETKEY crash, it crashed if the command did not succseed.
4237 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4240 is now real and not just an macro interface to GMP.
4242 Removed the entire GMP from the source tree and imported new
4243 NSS MPI library instead. Reason for removing GMP is that it is
4244 extremely large and compiles extremely slow. The NSS MPI
4245 is only a few files and compiles in less than 10 seconds.
4246 The speed is also about the same as GMP. The MPI is imported
4247 to lib/silcmath/mpi.
4249 If the system has GMP installed we will still use the GMP.
4250 If it is not then the NSS MPI will be compiled.
4252 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Merged a long nickname (127 characters long) crash bugfix from
4255 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4257 * Merged a freed memory reference bugfix from Irssi CVS tree.
4258 Affected file irssi/src/core/commands.c.
4260 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Added the server's public key sving and verification to the
4263 server when performing the SKE. This was missing and the
4264 remote server's (or router's) public key was accepted without
4265 checking whether we have it previously or trust it at all.
4266 Affected file silcd/protocol.c.
4268 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Check in the silc_server_timeout_remote if protocol is active
4271 and make sure that the protocol's final callback is called so
4272 that all memory if freed. Affected file silcd/server.c.
4274 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * silc_server_whois_send_reply crashed the server if the nickname
4277 was 127 characters long. Affected file silcd/command.c.
4279 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4281 * Added sanity check to the silc_server_new_client. If the hostname
4282 is provided inside username then check that the provided hostname
4283 really is the same as the resolved one. If the hostname was not
4284 resolved then check it from the public key. Affected file is
4285 silcd/packet_receive.c.
4287 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4288 if the server disconnected us and the connection is not valid
4289 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4291 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4292 the library to the lib/silcutil/silcutil.[ch].
4294 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4296 * Close log file after open. Affected file
4297 lib/silcutil/silclog.c.
4299 * Check whether sock == NULL in silc_client_send_packet and return
4300 if it is. Affected file lib/silcclient/silcclient.c.
4302 * Check rec->entry == NULL in the Irssi SILC Client before
4303 sending the channel message. Affecte file is
4304 irssi/src/silc/core/silc-servers.c.
4306 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Merged a splitted window bugfix from Irssi CVS tree. The
4309 affected file is irssi/src/fe-text/textbuffer-view.c.
4311 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4312 It did not print nickname.
4314 * Improved the distributions system a bit.
4316 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4319 irssi/src/fe-text/gui-window.c.
4321 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4322 to in-active server. The affected file is
4323 irssi/src/silc/core/client_ops.c.
4325 * Resolve the client in USERS command reply if the entry does
4326 not have username resolved. The affected file is
4327 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4328 command to WHOIS command to really resolve stuff. The USERS
4329 is not used any more in any critical section so WHOIS can
4330 be used even though it might be slower than IDENTIFY.
4332 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4335 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Changed the protocol API a bit more consistent in the
4338 lib/silccore/silcprotocol.[ch].
4340 * Changed the following headers to ROBODoc format:
4342 lib/silccore/silcpayload.h
4343 lib/silccore/silcprotocol.h
4344 lib/silccore/silcsockconn.h
4346 All core library headers are now formatted.
4348 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4350 * Fixed a bug in Irssi SILC client; do not show that you are
4351 server/router operator if you really are not. Affected file is
4352 irssi/src/silc/core/client_ops.c.
4354 * Renamed silc_command_free_payload to silc_command_payload_free.
4355 Affected file lib/silccore/silccommand.h
4357 * Added silcmath.h to include the prototoypes of various routines
4358 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4361 * Changed the following headers to ROBODoc format:
4363 lib/silccore/silcchannel.h
4364 lib/silccore/silccommand.h
4365 lib/silccore/silcid.h
4366 lib/silccore/silcidcache.h
4367 lib/silccore/silcmode.h
4368 lib/silccore/silcnotify.h
4369 lib/silccore/silcpacket.h
4370 lib/silcmath/silcmath.h
4372 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Added checking to the server code not to start the server if
4375 ciphers and stuff are not configured properly. Affected files
4376 silcd/serverconfig.[h] and silcd/server.c.
4378 * Changed the layout of the header files of the public interfaces
4379 in the SILC libraries. The new layout supports ROBODoc
4380 documentation tool (and some others) so that it is easy to create
4381 a library reference manual. All the other headers and source
4382 code must still follow the CodingStyle document. Also source
4383 code must not include these ROBODoc stuffs, only the headers.
4384 Furthermore, all public interface headers must now be named
4385 by using `silc' prefix, example: silcapi.h, silccipher.h.
4386 Some files were renamed due to this. All the other headers
4387 must not be used as public interfaces. I will update the
4388 CodingStyle document later. Changed following headers, so far:
4390 lib/silcclient/silcapi.h
4391 lib/silccore/silcauth.h
4392 lib/silccore/silcprivate.h
4393 lib/silccrypt/silcdh.h
4395 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4399 * Removed silc_client_packet_send_flush from the client library
4400 as it is not needed. Affected file lib/silcclient/client.[ch].
4402 * Added printing of message of unresolved authentication method
4403 to the Irssi SILC client. Added it to the module formats.
4404 Removed the same message from the client library.
4406 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Added new distribution feature, DISTLABEL. Every distribution
4409 can define own preprocessor label that can be used in the
4410 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4411 file distributions, acconfig.h.pre and prepare.
4413 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4415 * Added Makefile.defines_int to include the actual definitions
4416 for Makefile.defines.in. Tested the new distribution system,
4417 created distributions and tested installation.
4419 * Added AWAY message printing to the Irssi SILC client. Added
4420 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4422 * Added SCONNECT command to call the SILC's CONNECT command.
4423 Cannot use CONNECT directly since Irssi uses that internally.
4424 Affected file irssi/src/silc/core/silc-servers.c.
4426 Added ACTION local command. It is same as ME command but takes
4427 the channel as mandatory argument.
4429 Rewrote some of the Irssi's help files to suite for SILC
4432 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Added Makefile.defines[.in] that should for now on be included
4435 in all Makefile.am file in the source tree. That file includes
4436 all common compilation definitions for SILC source tree.
4438 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Minor changes to the ./prepare script to change the package
4441 name according the distribution name to the configure.in.
4443 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Created new distribution system. Added file `distributions'
4446 that defines all the distributions that can be created out of
4447 the SILC source tree. The ./prepare script now reads that
4448 file to determine how to prepare the distributions. The
4449 first argument to the ./prepare is the name of the distribution
4450 and second is the version of the distribution. If given
4451 without arguments it creates the default (toolkit) distribution
4452 with the default version (defined in ./prepare).
4454 All Makefile.am files that are subject to the distributions
4455 are now named as Makefile.am.pre. These are ./Makefile.am
4456 and lib/Makefile.am. Others may be changed later.
4458 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4460 * Added invite list, ban list, some key management and connection
4461 error message printing to module formats in the Irssi SILC client.
4463 * Added new silc_client_set_away_message to set the away message
4464 that is back to the person who sent private message. The
4465 affected file lib/silcclient/silcapi.h and the
4466 lib/silcclient/client_prvmsg.c.
4468 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Fixed the private message sending in the Irssi SILC client,
4471 added local command KEY to the Irssi SILC client.
4473 Added key management and key agreement message formats to the
4474 irssi/src/fe-common/silc/module-formats.[ch].
4476 Added USERS (alias WHO) printing, server/router operator
4477 indication and LIST command printing to the module formats.
4479 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4481 * Fixed channel joining notify handling, cumode notify handling
4482 from Irssi SILC client.
4484 * Added SILC specific module-formats to the Irssi SILC client so
4485 that SILC specific message hilighting, colors etc is possible.
4486 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4488 Added channel mode, channel user mode, actions, notices,
4489 whois and whowas printing to the the module-formats.c.
4491 * Fixed a bug in channel deletion in the server. The channel
4492 is not left to the cache even if the channel founder auth mode
4493 is set when there are no users anymore on the channel. Affected
4494 file silcd/server.c.
4496 * The silc_net_localhost now resolves the entire hostname including
4497 the domain name. Affected file lib/silcutil/silcnet.c.
4499 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4501 * Changed the ask_passphrase client operation to be ascynchronous.
4502 It has now a completion callback and a context that the
4503 application must call after it has got the passphrase from
4504 the user. Affected files lib/silcclient/silcapi.h,
4505 lib/silcclient/protocol.c, lib/silcclient/command.c and
4508 Added SilcAskPassphrase callback that the application calls
4509 to deliver the passphrase to the library.
4511 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4512 The public key verification and especially a certificate
4513 verification is asynchronous procedure.
4515 Added new SILC_SKE_STATUS_PENDING status to indicate the
4516 request is pending and a callback will be called to finalize
4519 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4520 indicate that remote end did not send its public key (or
4521 certificate), even though we require it. Added check for this
4522 condition in the SKE. This was a security bug, now fixed.
4524 Defined new SilcSKEVerifyCbCompletion callback that is called
4525 when the verification process is completed.
4527 The affected files lib/silcske/silcske_status.h and
4528 lib/silcske/silcske.[ch].
4530 * Changed the verify_public_key client operation to be async
4531 as well. Defined SilcVerifyPublicKey callback that is used to
4532 indicate the success of the public key verification process.
4534 Changed the server and client to use the new async client
4537 * Changed the Irssi SILC client's internal scheduler to be called
4538 twice as many times as it used to be. As a result the client
4539 should be a bit faster now. Affected file is
4540 irssi/src/silc/core/silc-core.c.
4542 * Added support to Irssi SILC client of asynchronous public key
4543 verification and passphrase inquiry. Affected file is
4544 irssi/src/silc/core/silc-core.c.
4546 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Do not say "You have left channel %s" in client library.
4549 Moved it to the application. Affected files are
4550 lib/silcclient/command.c and silc/client_ops.c.
4552 * Fixed silc_client_get_clients. Command context was not
4553 duplicated and was freed memory in the callback. Affected
4554 file lib/silcclient/idlist.c.
4556 * Do not say "you are now talking..." on JOIN command in the
4557 client library. The appliation must handle it.
4559 * Do not say ".. changed topic to" in command reply in the
4560 client libary. The application must handle it.
4562 * Fixed TOPIC command sending in the client library.
4564 * Fixed a memory leak in silc_client_command_free in the file
4565 lib/silcclient/command.c.
4567 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Imported a modified version of Irssi client to the source tree.
4570 The Irssi will be used to create a new client called
4571 Irssi SILC. Imported to irssi/.
4573 Added silc_core_init_finish function to the Irssi. Affected
4574 file irssi/configure.in.
4576 A lot changes in the Makefile.ams around the irssi tree.
4578 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Do not rehash if the new size is same as the old size of the
4581 hash table, in the silc_hash_table_rehash*. The affected file
4582 lib/silcutil/silchashtable.c.
4584 * Replaced hash_table_del_by_context calls from the server
4585 (when channel->user_list and client->channels) to the
4586 hash_table_del as it is sufficient and faster.
4588 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Added silc_hash_table_list, silc_hash_table_get and the
4591 SilcHashTableList structure to provide an alternative way to
4592 traverse the hash table. The affected files are
4593 lib/silcutil/silchashtable.[ch].
4595 * Changed the server's idlist routines to use the hash table
4596 routines to optimize the code.
4598 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Replaced the client entry's `channel' list and channel entry's
4601 `user_list' list to hash tables for optimized lookup. Changed
4602 the code to use the hash table interface around the code.
4603 Affected file lib/silcd/idlist.[ch].
4605 * Added `auto_rehash' boolean argument to the function
4606 silc_hash_table_alloc to indicate whether the hash table should
4607 auto-rehash when it thinks is appropriate time. It will
4608 increase the hash table size if the there is twice as much
4609 entries in the table than the size of the table, and will
4610 decrease the size if there are twice as less entries than
4611 the size of the table.
4613 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4617 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * silc_idcache_purge_by_context deletes the entry now by context
4620 as it is supposed to do. Affected file lib/silccore/idcache.c.
4622 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4623 client is not anymore valid (WHOWAS givens the info) and not
4624 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4626 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4628 * Removed the `data' and `data_len' arguments from the ID Cache
4629 interfaces and added `name' argument. ID Cache does not handle
4630 anymore the binary data only a names associated with given ID.
4632 * When hashing a Client ID with silc_hash_id the entire ID is
4633 not hashed anymore, instead only the hash of the Client ID is
4634 hashed. This way we can access the Client ID from the cache
4635 with Client ID but with the hash of the ID (which is a hash of
4636 the nickname) as well without any difference in performance.
4638 Added also silc_idcache_find_by_id_one_ext to do one on one
4639 searching when we have the actual ID. Added also function
4640 silc_hash_client_id_compare. The affected files are
4641 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4643 * When hashing the name associated with a ID it is always done
4644 in lowercase. This way we can access the cache without worrying
4645 about case-sensitivity, even though, for example nicknames are
4648 * Fixed a bug in server with channel message sending. It put
4649 wrong ID type as destination ID. The affected file
4650 silcd/packet_send.c.
4652 * silc_idcache_del_by_context now deletes from all hash tables
4653 by context. Affected file lib/silccore/idcache.c.
4655 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Changed the client library to use the new ID Cache interface.
4658 Changes around the source tree.
4660 * Added silc_hash_table_rehash_ext to rehash with specific
4661 hash function. Affected file lib/silcutil/silchashtable.[ch].
4663 * Added silc_hash_string_compare to compare two strings in the
4664 hash table. Affected file lib/silcutil/silcutil.[ch].
4666 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4668 * Added new function silc_idcache_del_by_context into the
4669 lib/silccore/idcache.[ch].
4671 * Changed the server's ID list routines to use the new ID Cache
4672 interface. Changes around the source tree.
4674 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Added silc_hash_table_del[_by_context]_ext functions in to the
4677 lib/silcutil/silchashtable.[ch].
4679 Removed silc_hash_table_find_all* routines and added new
4680 silc_hash_table_find_foreach to replace them.
4682 Added silc_hash_table_replace_ext function as extended
4683 replacing function. Separated the simple hash table interface
4684 from the extended hash table interface in the file
4685 lib/silcutil/silchashtable.h.
4687 * Fixed minor bugs and changed it to use some of the new
4688 hash table functions in lib/silccore/idcache.c
4690 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4692 * Added new function silc_hash_table_find_all to return all keys
4693 in the hash table by the specified key. As the hash table is
4694 collision resistant it also makes it possible to have several
4695 duplicate keys in the hash table. This function may be used to
4696 find all of the keys from the hash.
4698 Added user_context arguments to the SilcHashFunction,
4699 SilcHashCompare and SilcHashDestructor to deliver user specified
4702 Added new fuctions silc_hash_table_find[_all]_ext to do
4703 extended lookup with specified hash and compare functions and
4704 specified user contexts.
4706 Added new function silc_hash_table_add_ext to add the key
4707 with specified hash function and user context.
4709 Added new function silc_hash_table_foreach to traverse all
4710 entrys in the hash table. Added SilcHashForeach callback
4713 Added new function silc_hash_table_del_by_context to delete
4714 the entry only if the context associated with the key matches.
4716 Affected files are lib/silcutil/silchashtable.[ch].
4718 * Removed silc_hash_[server/client/channel]_id and added just
4719 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4720 silc_hash_id_compare to compare two ID's using as the hash table
4721 comparison function. Added also silc_hash_data to hash
4722 binary data and silc_hash_data_compare to compare it.
4724 * Removed silc_idlist_find_client_by_hash as it is not needed
4725 anymore. Affected file silcd/idlist.[ch].
4727 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4728 to use internally the SilcHashTable. The new ID Cache is a lot
4729 faster than the old one. Some of the ID Cache interface was also
4730 rewritten and obsolete and stupid functions were removed.
4732 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * Added entry_count field to the SilcHashTable to keep the number
4735 of the entries in the table. Implemented the function
4736 silc_hash_table_rehash. Added new function
4737 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4739 Fixed a minor bug in silc_hash_table_free.
4741 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4742 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4743 into the lib/silcutil/silcutil.[ch].
4745 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4747 * Implemented a collision resistant hash table into the
4748 lib/silcutil/silchashtable[ch]. See the header and the source
4749 for the SilcHashTable API.
4751 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4753 * Merged dotconf version 1.0.2 into lib/dotconf.
4755 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4757 * Do not compile anything in lib/silcsim/* if the SIM support
4758 is not enabled. The tree should now compile without problems
4761 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Compiled the SILC under cygwin. Compiled and tested briefly
4764 without problems. More tests needed. The SIMs didn't compile
4767 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4769 * Fixed possible crash in silc_get_username in the
4770 lib/silcutil/silcutil.c.
4772 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4774 * Fixed a va_arg in silc/client_ops.c.
4776 * Oops, RC5 routines were named AES and caused some problems
4777 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4779 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Added new SilcIDIP structure into the lib/silccore/id.h and
4782 replaced the old `ip' fields from all SILC ID's to that type.
4783 This is a step towards IPv6 support.
4785 The silc_id_get_len takes now the ID as an extra argument.
4786 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4787 both IPv4 and IPv6 based ID's.
4789 The affected files are lib/silccore/id.[ch] and other files
4790 around the tree using these routines.
4792 * Removed the ID length arguments in server from various
4793 silc_server_send_notify_* routines -> they are not needed
4796 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4798 * Fixed memory leak in silc_encode_pem_file in the file
4799 lib/silcutil/silcutil.c.
4801 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Check minor version as well in the SKE. Affected files are
4804 silcd/protocol.c and lib/silcclient/protocol.c.
4806 * Added --identifier option to the server so that an identifier
4807 can be when creating the public key for the server. Affected
4808 file is silcd/silcd.c.
4810 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4811 lib/silccrypt/silcpkcs.c.
4813 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Register default ciphers and stuff when using -C option with
4816 the server. Affected file sildc/silcd.c.
4818 * Put back the servers public key filename format, it is better
4819 than the new one. For now, the client keys are saved with the
4820 new filename format. The affected file silc/client_ops.c.
4822 * Implemented the Cipher API for the rest of the ciphers that
4823 did not implement it or implemented it the wrong way.
4825 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4827 * Register default ciphers and stuff when using the -S option
4828 in the client. Affected file silc/silc.c. Same also when
4829 creating new key pair with -C option.
4831 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4833 * Fixed the silc_verify_public_key client operation function to
4834 save the public keys differently. The fingerprint is now
4835 used as filename and not the hostname. This way also the
4836 client keys are saved uniquely and not with hostnames. The
4837 affected file is silc/client_ops.c.
4839 * Trimmed the silc_hash_fingerprint function to remove extra
4840 whitespaces from the end of the fingerprint. The affected
4841 file is lib/silccrypt/silchash.c.
4845 * Added silc_cipher_register_default function to register all
4846 default ciphers. It can be used when configuration files
4847 does not exist and the application does not want any specific
4848 ciphers in any specific order.
4850 The SilcDList is now used as silc_cipher_list dynamically
4851 allocated cipher list. Removed the static list all together
4852 and now all ciphers must be allocated to the dynamic list.
4853 The silc_cipher_alloc routine was changed to check only the
4856 All silc_cipher_* routines that used to return int returns
4859 The affected files lib/silccrypt/silccrypt.[ch].
4861 * The same thing was done to silc_hash_* as for silc_cipher_*
4862 routines. Affected files lib/silccrypt/silchash.[ch].
4864 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4865 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4866 Added also silc_pkcs_[un]register[_default] functions.
4867 Removed the data_context from the PKCS API.
4869 * Added silc_hmac_register_default function to register default
4870 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4871 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4872 to unregister all hmacs at once.
4874 * Register the default ciphers, hash functions, PKCSs and HMACs
4875 if client's configuration file does not exist. The affected
4878 * The client did not load the hash functions from the SIM
4879 modules at all. Added support for this. Affected file is
4880 silc/clientconfig.c.
4882 * When decoding public key with silc_pkcs_public_key_decode, check
4883 the supported algorithm only if PKCS are registered. Affected
4884 file lib/silccrypt/silcpkcs.c. The same was done with the
4885 silc_pkcs_private_key_decode.
4887 * Fixed the SILC List routines to keep the list always in order.
4888 It used to change the list's order when traversing the list but
4889 not it preserves the order. Affected file lib/trq/silclist.h.
4891 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4893 * Added the client library to use the SilcSocketConnection's
4894 reference counter (by silc_socket_dup) to prevent the bug that
4895 the socket object may be freed underneath async operation.
4897 * The name resolv library checking fixes in the configure.in.pre.
4900 * Created new version of the protocol drafts for future
4901 development. The -03 drafts are the ones that will be changed
4902 in the trunk now and the -02 will remain as they are.
4904 * Send list of CUMODE notifys to the router when announcing
4905 the channel users to the router. Affected file silcd/server.c.
4906 If the router receiving channel founder CUMODE for a channel
4907 that already has channel founder it will send CUMODE notify
4908 to the sender to remove the channel founder rights from the
4909 announced client. Affected file silcd/packet_receive.c.
4911 * The CUMODE notify may now use Server ID as well as the entity
4912 who changes the mode. Updated protocool specs.
4914 * Updated INSTALL and README files.
4916 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * New web pages in the http://silc.pspt.fi. The pages was
4923 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Implemented the [DenyConnectin] config section in the server.
4926 Added silc_server_config_denied_conn to check whether incoming
4927 connection is denied. Affected file silcd/serverconfig.[ch].
4929 * Do not check the ports when checking the incoming configuration
4930 data if the port is 0, meaning any. Affected file is
4931 silcd/serverconfig.c.
4933 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Fixed buffer overflow in silc_string_compare in the file
4936 lib/silcutil/silcutil.c.
4938 * Fixed double free in silc_server_command_leave in the file
4941 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Fixed the version checking in the server. Affected file is
4946 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Fixed the configuration data fetching when accepting new
4949 connections in the server. Affected file silcd/server.c.
4951 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Added `sender_entry' argument to the function
4954 silc_server_packet_relay_to_channel so that we can check
4955 whether some destination actually belongs to the same route
4956 the sender belongs (ie, we must not resend the packet to the
4957 sender). Affected file silcd/packet_send.[ch].
4959 * Added `servername' field to the SilcClientEntry in the server
4960 to hold the name of the server where client is from. Affected
4961 file is silcd/idlist.h.
4963 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Moved the channel message encrypting in the router betwen
4966 router connections from silc_server_channel_message to the
4967 silc_server_packet_relay_to_channel since we want to check
4968 whether we have anybody channel before encrypting anything.
4969 Affected files silcd/packet_[receive/send].c.
4971 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Fixed the [AdminConnection] server config section to support
4974 multiple entries. Affected file silcd/serverconfig.c.
4976 * Added support into the server to check the validity of the
4977 incoming connection before executing any KE or authentication
4980 * The connection configuration is now saved to the KE and
4981 connection auth protocol contexts and not fetched anymore in
4982 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4984 * The local hosts listenning address and port is also resolved
4985 now when starting the server. We want to have the socket object
4986 to include the real address and port for the listener. Added
4987 new function silc_net_check_local_by_sock into the files
4988 lib/silcutil/silcnet.[ch].
4990 * Fixed a broadcast bug in server -> do not broadcast if we
4993 * Fixed a routing bug. Do not route broadcast packets ever.
4994 Broadcast packets must be processed always and not routed since
4995 they may be destined to some other host than yourself and thus
4996 would get routed without no good reason. Affected file is
4999 * Added function silc_server_config_is_primary_route to check
5000 whether primary router connection has been configured (a router
5001 configuration that we are initiating). If there is not, we
5002 will assume that there is only two routers in the SILC network
5003 and we will use the incoming router connection as our primary
5004 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5006 * Changed the order of the broadcasting. Broadcast _after_ the
5007 packet has been processed not before. Affected file is
5010 * Fixed a [ClientConnection] parsing bug. The port was never
5011 parsed correctly thus resulting to port 0. Affected file
5012 silcd/serverconfig.c.
5014 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5015 argument and did not set the broadcast packet flag. Affected
5016 file silcd/packet_send.c. Fixed same bug in the function
5017 silc_server_send_notify as well.
5019 * If we receive NEW_ID packet for our own ID in the server, ignore
5022 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5026 * Removed the nickname from the Private Message Payload.
5027 Updated the code and the protocol specs.
5029 * Updated protocol specs for submitting to the IETF.
5031 * Tweaked the Random Number Generator a bit. Affected file
5032 lib/silccrypt/silcrng.c. Exported a new function
5033 silc_rng_[global]_add_noise which can be used to add more
5036 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Do not parse packets with different timeout when protocol
5039 is active -> may cause problem with rekey. Affected file
5042 * When server receives signoff notify it must not create
5043 new channel key if the client is on any channels since the
5044 sender of the signoff notify will create it.
5046 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5048 * Added printing of error messages during SKE protocol from the
5049 failure packet sent by server during SKE. Affected file
5052 * Removed the client's failure_callback handling with timeout
5053 and handle it immediately when received.
5055 * The SKE library returned wrong type in SUCCESS and FAILURE
5056 packets. They must be 32 bit MSB not 16 bit MSB.
5058 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * Ok, rewrote the logic of the re-key and now it seems to work.
5061 I tested it on high traffic with frequent re-keys without
5062 problems. Added hmac_receive (and renamed hmac to hmac_send)
5063 in SilcClientConnection in lib/silcclient/client.h and
5064 in SilcIDListData in silcd/idlist.h. Also, removed the
5065 SilcPacketParserContext's cipher and hmac fields as they are
5066 not needed anymore and actually caused some problems when
5067 the ciphers and hmac's changed underneath the packet parser.
5069 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * If re-key protocol is active then process the incoming packets
5072 synchronously since we must assure that icoming packets encrypted
5073 with the old key is processed before the new keys is set to
5074 use. This is true other packets than for REKEY packets.
5075 Affected file silcd/server.c. The same was done to client library
5076 as well, affected file lib/silcclient/client.c.
5078 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5080 * Fixed bug in client and server to accept the force send if
5081 the packet is send from silc_[server/client]_packet_process
5082 function. Otherwise the packets are never delivered, oops.
5084 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Disable force sending of packets when REKEY protocol is active.
5087 We must assure that no packet is sent directly when rekey is
5088 performed. All packets must be sent through packet queue.
5089 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5090 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5091 function is silc_[server/client]_packet_send_real to check
5094 * Replaced the SIM paths from example config files to
5095 /usr/local/modules. Also, make install creates now
5096 /usr/local/silc/logs directory to hold all the SILC server
5099 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Made the configure.in.pre work on Solaris. Patch by salo.
5103 * Made all ciphers compatible with non-x86 machines. Defined
5104 CBC mode macros into lib/silccrypt/ciphers_def.h.
5106 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Fixed the make install.
5110 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * When MAC computation fails the silc_packet_decrypt returned 0
5113 even though it was supposed to return -1. Fixed this. The
5114 affected file is lib/silccore/silcpacket.c.
5116 * Do not replace the config files in /etc/silc (in make install)
5117 if they already exist. Affected file ./Makefile.am.
5119 * Do not send re-key packets immediately but through packet queue.
5120 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5122 * Changed silc_net_check_host_by_sock to return FALSE if the
5123 IP/DNS could not be resolved. Though, it returns the IP address
5124 now even if it could not resolve it (but returns also FALSE).
5125 Affected file lib/silcutil/silcnet.[ch].
5127 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Added silc_pkcs_decode_identifier to decode the public key's
5130 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5131 Added also silc_pkcs_free_identifier. Added also new context
5132 SilcPublicKeyIdentifier.
5134 * Added -S option to the silc client. It is used to dump the
5135 contents of the specified public key file.
5137 * Changed the PKCS api to return the public key length when
5138 setting the public key.
5140 * Fixed a fatal bug in the public and private key file loading.
5141 Affected file lib/silccrypt/silcpkcs.c.
5143 * Execute the packet parsing for client with zero (0) timeout
5144 if the protocol is active. Affected file silcd/server.c.
5146 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Made the key generation options to the silcd program. Added
5149 -C option, equivalent to client's option.
5151 * Added new [ServerKeys] config section to the server. It
5152 configures the server's public and private key.
5154 * Defined generic Public Key Payload into the protocol
5155 specification to send specific type of public keys and
5158 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5159 public key or certificate.
5161 * Implemented the GETKEY command to the server and to the
5162 client library and on user interface.
5164 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5166 * Made preliminary `make install' work.
5168 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5170 * Added SilcServerRekey context into silcd/idlist.h.
5172 * Added the PFS support as defined in the specification to the
5173 SKE protocol. Affected files lib/silcske/*.c.
5175 * Added `ske_group' field to the SilcServerRekey context to hold
5176 the number of the SKE group that is used with PFS in re-key.
5177 Affected file silcd/idlist.h.
5179 * Added PFS re-key support to the server. Affected file is
5182 * Added silc_protocol_cancel to cancel execution of the next
5183 state of the protocol. Affected file is
5184 lib/silccore/silcprotocol.[ch].
5186 * Added the re-key support with and without PFS to the client
5187 library. Re-key is performed once in an hour, by default.
5189 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5190 Added silc_client_rekey_callback and silc_client_rekey_final.
5191 Affected files are lib/silcclient/protocol.[ch] and
5192 lib/silcclient/client.[ch].
5194 * Removed the `hmac_key' and `hmac_key_len' fields from the
5195 SilcClientConnection structure; not needed. Affected file is
5196 lib/silcclient/client.h.
5200 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Do not ask whether user wants to use the negotiated private key
5203 for private messages, just use it. Affected file is
5204 silc/local_command.c.
5206 * Added `send_enc_key' and `enc_key_len' fields to the
5207 SilcIDListData structure since they are needed in the re-key
5208 phase. Affected file is silcd/idlist.[ch].
5210 * Implemented the simple re-key protocol into the server.
5211 Affected files silcd/server.c and silcd/protocol.[ch]. The
5212 re-key will be performed once in an hour, by default.
5214 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5215 Added silc_server_rekey, silc_server_rekey_callback and
5216 silc_server_rekey_final.
5218 * Removed Tunneled flag from the protocol. Updated the code
5219 and the specifications.
5221 * Adde `pfs' field to the SilcIDListData to indicate whether
5222 the PFS is to be performed in the re-key. Affected file is
5225 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5227 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5228 int64 of at least the xintXX size. If void * is less that 4
5229 bytes uint32 * will be used. Defined bool as boolean.
5231 * Changed _ALL_ unsigned long and unsigned int to uint32,
5232 unsgined short to uint16 in the source tree.
5234 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5235 not handle clients that has entry->data.registered == FALSE.
5236 They are not in the network anymore. Affected file is
5239 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Implemented the sending of the SERVER_SIGNOFF notify in the
5242 server. Affected file is silcd/server.c.
5244 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5245 Added also silc_notify_payload_encode_args into the
5246 lib/silccore/silcnotify.[ch].
5248 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5249 Affected file silcd/packet_receive.c.
5251 * Implemented the SERVER_SIGNOFF notify handling in the client
5252 library. Affected file lib/silcclient/client_notify.c. Also,
5253 implemnted the printing of the SERVER_SIGNOFF info to the
5254 application. Affected file silc/client_ops.c.
5256 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5257 if the deleting was successful. Affected file silcd/idlist.[ch].
5259 * Added support for public key authentication in the connection
5260 authentication protocol in the client library. Affected file
5261 lib/silcclient/protocol.c.
5263 * Changed the server's silc_idlist_get_clients_by_* interface
5264 to support already allocated array so that new entries may be
5265 added to pre-allocated array. Affected file silcd/idlist.[ch].
5266 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5267 and command replies.
5269 * All command reply functions in the server now calls the
5270 pending command callback even if error occured. This way the
5271 error will be delivered to the client as well. Affected files
5272 silcd/command.c and silcd/command_reply.c.
5274 * Fixed INFO command to return local server's info if no server
5275 was provided. Affected file lib/silcclient/command.c.
5277 * Removed RESTART command for good. Updated the code and the
5280 * Rewrote parts of the task system. It is a bit simpler now.
5281 Removed unsued task priorities. The affected files are
5282 lib/silcutil/silctask.[ch].
5284 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Moved the USERS printing from the library to the application.
5287 Affected files lib/silcclient/command.c and silc/client_ops.c.
5289 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Added channel key re-key support. The re-key is perfomed
5294 only by the router and is done once in an hour. Added `rekey'
5295 field to the SilcChannelEntry in the server. Affected files
5296 silcd/server.c and silcd/idlist.h.
5298 * Added silc_task_unregister_by_context into the file
5299 lib/silcutil/silctask.[ch].
5301 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Added SILC_UMODE_GONE mode to indicate when the client is not
5304 present in the SILC network. Added also support to the local
5305 command AWAY that will set this mode. Added support of showing
5306 "xxx is gone" in WHOIS command. The USERS command shows the
5307 gone status as well.
5309 * Fixed setting server and router operator privileges in the
5310 server's UMODE command. Affected file silcd/command.c.
5312 * Merged the SKE KE1 and KE2 payloads into one payload. The
5313 new KE payload is equivalent to the old KE2 payload.
5315 Cleaned up the SKE Start Payload parsing. It now uses the
5316 simple buffer unformatting to do the parsing. A lot faster
5319 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5320 to the SKE that is used to indicate whether both of the SKE
5321 parties should perform authentication. By default only the
5322 responder performs authentication. By setting this flag also
5323 the initiator must do authentication. By default it is unset
5324 since in normal SKE case, client to server connection, only
5325 the responder should do authentication. When doing SKE between
5326 two clients both should perform authentication. Updated the
5327 code and the protocol specs.
5329 * A little fix to IDENTIFY command in the server. Search the
5330 client first by hash not nickname. Affected file is
5333 * Fixed the silc_client_close_connection to support closing
5334 the client to client connections wihtout deleting too much
5335 data. Affected file lib/silcclient/client.c.
5337 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5338 are received if protocol used to be active but is not anymore
5339 the application would crash due to NULL pointer dereference.
5340 Affected files silcd/server.c and lib/silcclient/client.c.
5342 * Added `hash' field to the SilcClientConnection to include
5343 the hash function negotiated in the SKE protocol.
5345 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5346 to set the channel founder authentication data. A client can
5347 claim the founder rights later by providing the authentication
5348 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5349 This way the channel founder can regain the channel founder
5350 privileges even it is left the channel. This works only on
5351 local server and the client must be connected to the same
5352 server to be able to regain the founder rights. Updated the
5353 protocol specs accordingly.
5355 Added support to the CMODE command in the client to set the
5356 founder auth data. Read the README to see how to set it.
5358 Added support to the CUMODE command to claim the founder
5359 rights. Read the README to see how to do it.
5361 Added support for the founder authentication to the Channel
5362 Entry in the server. Affected file silcd/idlist.h.
5364 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5365 server's CMODE command. Affected file silcd/command.c.
5367 * Added the following new functions into lib/silccore/silcauth.[ch]:
5368 silc_auth_get_method and silc_auth_get_data.
5370 * The server now saves the remote hosts public key to the
5371 SilcIDListData pointer. Affected file silcd/protocol.c.
5373 * The normal server now does not remove the channel entry from
5374 the cache if the founder authentication data is set. It used
5375 to remove it if the founder was the last one on the channel on
5376 the server and left the channel. The auth data is saved and
5377 if the channel is re-joined later the old entry is used with
5378 the old auth data. Affected files silcd/command_reply.c and
5381 * Removed the `pkcs' field from the SilcIDListData structure
5382 in the server; it is not used. Affected file silcd/idlist.h.
5384 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5386 * Fixed packet processing on slow links. Partial packets were
5387 never re-processed because the incoming data buffer was cleared
5388 by the application. Application must not directly clear the
5389 sock->inbuf, the packet processing routines handle it. Fixed
5390 this in client library and in server.
5392 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Fixed the WHOIS and IDENTIFY send reply function to really
5395 check whether to send list or just one entry. Affected file
5398 * Cleaned up the LEAVE command's channel key distribution. The
5399 affected file silcd/command.c.
5401 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5402 can enforce the channel mode as well. In that case the ID
5403 includes the ID of the server. The code now enforces the
5404 mode change if the router have different mode than the server.
5406 * The notify client operation with CMODE_CHANGE notify can now
5407 return NULL client_entry pointer if the CMODE was not changed
5408 by client. Application must check for this.
5410 * Added <Server ID> argument to INFO command to support server
5411 info fetching by Server ID.
5413 * Added silc_server_announce_get_channel_users to get assembled
5414 packets of channel users of the specified channel. Affected
5415 file silcd/server.[ch].
5417 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5418 was freed underneath the ID Cache.
5420 * Re-announce clients when the server received CHANNEL_CHANGE
5421 notify from the router. Affected file silcd/packet_send.c.
5423 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5426 crashed since it did not handle the fact that there is no cipher
5427 called "3" and didn't check the error condition. Now fixed.
5429 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5430 flag. It can be used to send message requests.
5432 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Implemented the RESTART command in the client.
5436 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5437 notice type messages. Added notice printing to the user
5440 * The channel keys are not re-generated if the channel's mode
5441 is PRIVKEY, ie private key on the channel exists. Affected
5442 files silcd/server.c and silcd/command.c.
5444 * Fixed a little bug in channel message delivery when channel
5445 private keys are set in the server. Affected file is
5446 silcd/packet_send.c.
5448 * Changed the setting on channel->on_channel = TRUE from the
5449 silc_client_save_channel_key to the JOIN command reply. The
5450 key payload is not received if the private channel key is set.
5451 Affected file lib/silcclient/command_reply.c and the
5452 lib/silcclient/client_channel.c.
5454 * When the CMODE_CHANGE notify is sent and the channel private
5455 key mode is removed the channel key must be re-generated in
5456 other cells as well. Added this support for the router in the
5457 silcd/packet_receive.c.
5459 * Added new local command NOTICE to send notice message on
5460 channel. Affected file silc/local_command.[ch].
5462 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Added new local command ME to the client. It is used to send
5465 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5466 some action. Affected file silc/local_command.[ch].
5468 * Changed channel_message and private_message client operations
5469 to deliver the message flags to the application. Added also
5470 the `flags' arguments to the silc_client_send_channel_message
5471 and silc_client_send_private_message functions. Affected file
5474 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Redefined the Private Message Payload to support private message
5477 keys and to support the new private message flags. Updated
5478 the protocol specs. Flags makes it possible to have for example
5479 CTCP style messages.
5481 * Added new type SilcPrivateMessagePayload and defined an API
5482 for it in the lib/silcclient/silcprivate.[ch].
5484 * Tested private message private keys successfully. Tested the
5485 private message key set, unset and list commands with the new
5488 * Redefined the Channel Message Payload to include the channel
5489 message flags (equal with private message flags) to support
5490 for example CTCP style messages.
5492 * Defined some of the message (for channel and private message)
5493 flags. Updated the protocol specs and added the flags to the
5494 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5496 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Added SilcKeyAgreementStatus type to the key agreement routines
5499 to indicate the current status and error if one occured.
5500 The status types are defined in the lib/silcclient/silcapi.h.
5502 * Added new local command KEY that is used to set and unset private
5503 keys for channels, set and unset private keys for private messages
5504 with remote clients and to send key agreement requests and
5505 negotiate the key agreement protocol with remote client. The
5506 key agreement is supported only to negotiate private message keys,
5507 it currently cannot be used to negotiate private keys for channels,
5508 as it is not convenient for that purpose.
5510 * Fixed a minor pending callback setting bug in the function
5511 silc_client_get_client_by_id_resolve, now the function works.
5512 Affected file lib/silcclient/idlist.c.
5514 * Added function silc_net_get_local_port to get local bound
5515 port by socket. Added to lib/silcutil/silcnet.[ch].
5517 * Added `sockets' and `sockets_count' fields to the SilcClient
5518 object. They hold the sockets of the listenning sockets in
5519 the client. Listenning sockets may be for example the key
5520 agreement server. Affected file lib/silcclient/client.[ch].
5521 Added functions the silc_client_add_socket and the
5522 silc_client_del_socket. They are exported to the application
5525 * Added ~./silc/clientkeys to support other client's public keys.
5527 * Renamed verify_server_key client operation to verify_public_key
5528 and added one argument to indicate the type of the connection
5529 (server, client etc.).
5531 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Added silc_server_connection_auth_request to handle the
5534 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5535 silcd/packet_receive.[ch].
5537 * Added silc_server_send_connection_auth_request into the
5538 silcd/packet_send.c to send the connection auth request packet.
5540 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5543 * Fixed the public key authentication in responder side in the
5544 server. The `auth_data' pointer includes the SilcPublicKey
5545 not the path to the public key. Affected file silcd/protocol.c.
5547 * Implemented the public key authentication in the initiator side
5548 in the server. Affected file silcd/protocol.c.
5550 * Removed the [RedirectClient] config section from the server
5551 configuration. Is not needed and I don't want to implement it.
5553 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Cleaned up the CMODE command in the server. It now works
5556 correctly and supports all the modes defined in the protocol.
5557 Affected file is silcd/command.c.
5559 * Added `hmac_name' field to the SilcChannelEntry in the server
5560 to hold the default HMAC of the channel. It can be set when
5561 creating the channel (with JOIN command). Affected files
5564 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5565 type to indicate the change of the current cipher and hmac
5566 on the channel. Client can safely ignore the <cipher> argument
5567 (if it chooses to do so) since the CHANNEL_KEY packet will
5568 force the channel key change anyway. The <hmac> argument is
5569 important since the client is responsible of setting the new
5570 HMAC and the hmac key into use.
5572 * Fixed the CMODE command in the client library as well.
5574 * Tested CMODE command in router environment successfully.
5576 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * Show the version of the remote client (or server) when connecting
5579 to the server. It is logged to the log file. Affected file
5580 is silcd/protocol.c.
5582 * Fixed the KILLED notify handling in the client library. The
5583 client must be removed from all channels when receiving the
5586 Also, do not remove the client entry when giving the KILL
5587 command but when the KILLED notify is received.
5589 * Removed silc_idlist_find_client_by_nickname from the server.
5590 Not needed anymore. Affected files silcd/idlist.[ch].
5592 * Implemented the CHANNEL_CHANGE notify type handling to the
5593 server. Affected file silcd/server.c.
5597 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Added silc_server_send_notify_invite to send the INVITE
5600 notify between routers.
5602 * Implemented the INVITE command correctly to the server.
5604 * Implemented the INVITE notify type handling in the server.
5606 * Implemented the INVITE command to the client library and on the
5609 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5611 * Added function silc_server_get_client_resolve to find the
5612 client entry by ID from all ID lists and then resolve it
5613 (using WHOIS) if it cannot be found. Affected file is
5616 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Implemented the BAN command to the client library.
5620 * The JOIN command in the server now checks the invite list
5623 * Changed the silc_command_reply_payload_encode_va and the
5624 silc_command_payload_encode_va to support that if argument is
5625 NULL it ignores and checks the next argument. Affected file
5626 lib/silccore/silccommand.c.
5628 * Added silc_server_send_notify_ban to send the BAN notify
5629 type between routers.
5631 * Chaned the silc_notify_payload_encode to support that if
5632 argument is NULL it ignores and checks the next argument.
5633 Affected file lib/silccore/silcnotify.c.
5635 * Tested ban lists in router environment successfully.
5637 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Implemented BAN command to the server, in silcd/command.[ch].
5641 * Removed the BAN and INVITE_LIST modes from the CMODE command
5644 * Added function silc_string_match to regex match two strings.
5645 Affected files lib/silcutil/silcutil.[ch].
5647 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Redefined parts of the SilcChannelEntry in the server to support
5650 the new ban and invite lists.
5652 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Redefined the INVITE command. The same command can be used to
5655 invite individuals to the channel but also to manage the invite
5656 list of the channel (to add to and remove from the invite list).
5657 Updated the protocol specs.
5659 * Added new command SILC_COMMAND_BAN that can be used to manage
5660 the ban list of the channel. Updated the protocol specs.
5662 * Removed the channel modes: the SILC_CMODE_BAN and the
5663 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5664 in the CMODE command. The equivalent features are now available
5665 using INVITE and BAN commands. Updated the protocol specs.
5667 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5668 in the network about change in the current ban list. The notify
5669 type is not used by the client.
5671 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5672 support the invite lists.
5674 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added new function silc_string_regexify that converts string
5677 including wildcard characters into regex string that can
5678 be used by the GNU regex library. Added into the file
5679 lib/silcutil/silcutil.[ch].
5681 Added silc_string_regex_combine to combine to regex strings
5682 into one so that they can be used as one regex string by
5683 the GNU regex library. Added into the file
5684 lib/silcutil/silcutil.[ch].
5686 Added silc_string_regex_match to match two strings. It returns
5687 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5689 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5691 * Imported GNU regex to the soruce tree into lib/contrib.
5692 Fixed some compiler warning from the regex.c.
5694 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Fixed MOTD command in the server to work in router environment.
5698 * Fixed the MOTD command in the client library to support
5699 the server argument in the command.
5701 * Added `nickname_len' argument to the silc_idlist_add_client
5702 in the server, as the `nickname' argument may be binary data
5705 * Added silc_idlist_get_channels to return all channels from
5708 * Implemented LIST command to the server. Affected file is
5711 * Implemented the LIST command to the client library and on the
5714 * Added [<user count>] argument to the LIST command reply.
5715 With private channels the user count is not shown.
5717 * Updated TODO and README.
5719 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * The client entry's data.registered must be TRUE even with
5722 global client entry on global client list. The data.registered
5723 is used to check whether the client is anymore in the network,
5724 for example with WHOWAS command so it must be valid.
5726 * Fixed the WHOWAS command in the server. It now actually works
5727 in router environment. Added function into silcd/command_reply.c
5728 silc_server_command_reply_whowas_save.
5730 * Added silc_idlist_purge function to the silcd/idlist.c
5731 to periodically purge the ID Cache.
5733 * Fixed INFO command in the server. It works now in router
5734 environment. Added <server name> argument to the INFO command
5735 reply. Updated the protocol specs.
5737 * Fixed minor bug in silc_idcache_purge to not purge if the
5738 expire value is zero.
5740 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5741 they were buggy because of the WHOWAS information.
5743 * Fixed local command MSG to handle the async resolving of
5744 the remote client properly. It used to fail the first MSG.
5745 Affected file silc/local_command.c.
5747 * Added `data_len' field to SilcIDCache context.
5749 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Update TODO. Todo in commands in the server.
5753 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5755 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5756 used by routers as broadcast packet to inform other routers
5757 about the changed user mode.
5759 Implemented the notify handling in the server. Affected file is
5760 silcd/packet_receive.c. Added the function
5761 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5763 * Added new generic Channel Payload and deprecated the New Channel
5764 Payload. The New Channel Payload is now the generic Channel
5767 * Added new argument `mode' to the silc_server_send_new_channel
5768 as it is required in the Channel Payload now.
5770 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5771 and created a new and real SilChannelPayload to represent the
5772 new generic Channel Payload. Implemented the encode/decode
5773 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5775 * Added silc_server_get_client_channel_list to return the list
5776 of channels the client has joined for WHOIS command reply.
5777 Affected file silcd/server.[ch].
5779 * Implemented the channel list sending in the WHOIS command reply
5780 in server and in the client.
5782 Implemented the channel list displaying on the user interface
5783 as well. Affected file silc/client_ops.c.
5785 * Added silc_channel_payload_parse_list to parse list of Channel
5786 Payloads. It returns SilcDList list of SilcChannelPayloads.
5787 Client for example can use this function to parse the list of
5788 channels it receives in the WHOIS command reply. The caller
5789 must free the list by calling silc_channel_payload_list_free.
5790 Affected files lib/silccore/silcchannel.[ch].
5792 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Added one new argument <user mode> to the WHOIS command reply
5795 to return the mode of the user in SILC. Updated the protocol
5798 Implemented it to the server and client.
5800 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Fixed the mode printing on the user interface on joining.
5803 Affected file silc/client_ops.c.
5805 * Implemented the UMODE command and user modes in general to the
5806 client library and to the user interface.
5808 * Implemented the UMODE command to the server.
5810 * The server now sends UNKNOWN_COMMAND error status if client sends
5811 unknown command. Affected file silcd/command.c.
5813 * All server commands now handle the command identifier the right
5814 way when sending the command reply to the client. The client can
5815 use to identify the command replies with the identifier.
5817 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5819 * Added silc_server_get_client_route to resolve the route to
5820 the client indicated by the client ID. Affected file is
5823 * Added silc_server_relay_packet as general function to relay
5824 packet to arbitrary destination. This deprecates functions
5825 like _send_private_message_key, _relay_notify etc. Affected
5826 file is silcd/packet_send.[ch].
5828 Removed silc_server_send_key_agreement,
5829 silc_server_send_private_message_key and
5830 silc_server_packet_relay_notify functions from the file
5831 silcd/packet_send.[ch].
5835 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5836 server. Affected file silcd/packet_receive.[ch].
5838 * Implemented the KILL command to the client. Implemented the
5839 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5840 Affected files lib/silcclient/command[_reply].c and
5841 lib/silcclient/client_notify.c. Implemented the KILL notify
5842 printing in the user inteface.
5844 * Fixed a lot silc_parse_nick memory leaks from the client
5845 library in the file lib/silcclient/command.c.
5847 * Changed the silc_server_send_notify_on_channels's `sender'
5848 argument from SilcSocketConnection to SilcClientEntry to
5849 check the sender as entry and not as connection object and not
5850 to send to the client provided as argument. The affected file
5851 is silcd/packet_send.[ch].
5853 * The notify packets that are destined directly to the client used
5854 to not to be processed by the server. Now changed that and the
5855 server processes all notify packets. After relaying the packet
5856 to the client the notify packet is processed in the server.
5858 * The silc_server_free_client_data now checks whether there is
5859 pending outgoing traffic for the client and purges the data to
5860 the network before removing the client entry.
5862 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5864 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5865 an client is killed from the SILC Network. Updated the protocol
5868 Added new function silc_server_send_notify_killed to the
5869 silcd/packet_send.[ch].
5871 * Added function silc_server_packet_relay_notify to relay notify
5872 packets that are destined directly to a client. In this case
5873 the server does not process the notify packets but merely relays
5874 it to the client. Affected file silcd/packet_send.[ch].
5876 Added also silc_server_packet_process_relay_notify to check
5877 whereto relay the notify. Affected file is
5878 silcd/packet_receive.[ch].
5880 * Implemented the KILL command to the server.
5884 * Added the backup schema desgined last fall to the protocol
5885 specs for everyone to see. The specification is in the
5886 *-spec-xx.txt draft and the packet type definitions for the
5887 backup routers is in *-pp-xx.txt draft. Thusly, added also
5888 new packet type SILC_PACKET_CELL_ROUTERS.
5890 * A big security problem in the implementation discovered. The
5891 signoff of an client did not cause new channel key generation
5892 which it of course should've done. The channel keys must be
5893 always re-generated when client leaves (or signoffs) the channel.
5894 The silc_server_remove_from_channels funtion now handles
5895 the channel key re-generation.
5897 * Added `sender' argument to the silc_server_send_notify_on_channels
5898 to not to send the client provided as argument. Affected file
5899 silcd/packet_send.[ch].
5901 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Implemented OPER and SILCOPER commands into the server and
5906 * Added silc_auth_verify and silc_auth_verify_data to verify
5907 the authentication directly from the authentication payload.
5908 It supports verifying both passphrase and public key based
5909 authentication. Affected file lib/silccore/silcauth.[ch].
5911 * Added `hash' field to the SilcIDListData structure. It is the
5912 hash negotiated in the SKE protocol. Affected file is
5915 * Slight redesigning of the SilcAuthPayload handling routines.
5916 Do not send SilcPKCS but SilcPublicKey as argument.
5918 * Implemented the public key authentication support to the
5919 serverconfig. The public key is loaded from the provided path
5920 and saved as authentication data to void * pointer. Thus,
5921 changed the unsigned char *auth_data to void *auth_data;
5923 * Fixed SHUTDOWN command to send the reply before the server
5924 is shutdown. :) Affected file silcd/command.c.
5926 * Fixed fatal bug in CONNECT command. The hostname was invalid
5927 memory and server crashed. Affected file silcd/command.c.
5929 * Fixed fatal bug in CLOSE command. The server_entry became
5930 invalid but was referenced later in the command. Affected file
5933 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Fixed fatal bug in failure packet handling. Server ignored
5936 the failure and thus crashed when it came.
5940 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5943 that the command may be executed only once in (about) 2 seconds.
5944 The old SILC_CF_LAG flag is same but allows command bursts up
5945 to five before limiting.
5947 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5948 server code. Various commands now includes the CF_LAG_STRICT
5949 flag to disallow any kind of miss-use of the command.
5951 * Fixed the silc_buffer_unformat to not to allocate any data
5952 if the length of the data is zero. It used to allocate the
5953 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5955 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Changed the format of AdminConnection configuration section
5958 in the server. Added username of the admin to the format.
5959 Affected files silcd/serverconfig.[ch].
5961 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5962 to return admin configuration data by host, username and/or
5965 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Implemented WHOWAS command to the server. Added the functions:
5969 silc_server_command_whowas_parse,
5970 silc_server_command_whowas_send_reply,
5971 silc_server_command_whowas_from_client and
5972 silc_server_command_whowas_from_server
5974 * Added <Client ID> argument to the WHOWAS command reply. Updated
5975 the protocol specs accordingly.
5977 * Implemented WHOWAS command and command_reply to the client
5980 Implemented the WHOWAS printing on the user interface.
5982 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Added new argument to the WHOWAS command reply, the real name.
5985 It is an optional argument. Updated the protocol specs.
5987 * Added SilcIDCacheDestructor callback that is registered when
5988 the SilcIDCache is allocated. The callback is called when
5989 an cache entry in the ID Cache expires, or is purged from the
5990 cache. Added into lib/silccore/idcache.[ch].
5992 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5993 to destruct the client entries when the cache entry expires.
5994 Other ID Cache's in server and in the client library ignores
5997 * If the ID Cache entry's `expire' field is zero then the entry
5998 never expires. Added boolean `expire' argument to the
5999 silc_idcache_add function in the lib/silccore/idcache.[ch].
6000 If it is TRUE the default expiry value is used.
6002 * Added silc_server_free_client_data_timeout that is registered
6003 when client disconnects. By default for 5 minutes we preserve
6004 the client entry for history - for WHOWAS command.
6006 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6008 * Added support to the server to enforce that commands are not
6009 executed more than once in 2 seconds. If server receives
6010 commands from client more frequently, timeout is registered
6011 to process the commands. Affected file silcd/command.c.
6012 Added new function silc_server_command_process_timeout.
6014 * Changed NICK_NOTIFY handling in client library to check that
6015 if the client's nickname was changed, so there is no need to
6016 resolve anything from the server.
6018 * Removed error printing from the WHOIS and IDENTIFY commands.
6019 If error occurs then it is ignored silently in the client library.
6020 The application, however, may map the received error to
6021 human readable error string. The application currently maps
6022 the NO_SUCH_NICKNAME error to string.
6024 * Made the command status message public to the application. Moved
6025 them from lib/silcclient/command_reply.c to
6026 lib/silcclient/command_reply.h. The application can map the
6027 received command status to the string with the
6028 silc_client_command_status_message function.
6030 * Added check to the server to check that client's ID is same
6031 as the Source ID in the packet the client sent. They must
6034 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Added dist-bzip hook to the Makefile.am to make bzip2
6037 compressed distributions.
6039 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Server now enforces the maximum length for the nickname and
6042 the channel as protocol specification dictates. 128 bytes for
6043 nickname and 256 bytes for channel name.
6045 * Moved the WHOIS printing to the application. The client libary
6046 does not print out the WHOIS information anymore, the application
6047 must do it. Renamed silc_client_command_reply_whois_print to
6048 the silc_client_command_reply_whois_save.
6050 The client's idle time is also sent to the application now, and
6051 the idle is shown on screen.
6053 * Added silc_client_command_reply_identify_save to save the
6054 received IDENTIFY entries.
6056 * Do not check for channel private keys in message sending and
6057 reception if the channel does not have the PRIVKEY mode set.
6058 Affected file lib/silclient/client_channel.c.
6060 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6063 just surfaced after chaning the JOIN procedure.
6065 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Added silc_client_get_clients_by_list to get client entries
6068 from Client ID list, that is returned for example by JOIN
6069 and USERS command replies. The application should use this
6070 function for example when JOIN command reply is received to
6071 resolve the clients already on the channel (library does not
6072 do that anymore as USERS command reply is not used in the JOIN
6073 procedure anymore). Affected files lib/silcclient/silcapi.h and
6074 lib/silcclient/idlist.c.
6076 * JOIN command reply and USERS command reply returns now SilcBuffer
6077 pointers instead of unsigned char pointers when returning
6078 the client list and mode list.
6080 * Added <Client ID> argument to the JOIN command reply, mainly
6081 for the server to identify for which client the command was
6082 originally sent. Updated protocol specs accordingly.
6084 * Added SilcDlist private_key pointer to the SilcChannelEntry
6085 in the client to support the channel private keys. Affected
6086 file is lib/silcclient/idlist.h.
6088 * Added SilcChannelPrivateKey argument to the function
6089 silc_client_send_channel_message so that application can choose
6090 to use specific private ke if it wants to. If it is not provided,
6091 the normal channel key is used, unless private keys are set.
6092 In this case the first (key that was added first) is used
6093 as the encryption key.
6095 * Implemented the support for channel private key handling.
6096 Implemented the following functions:
6098 silc_client_add_channel_private_key,
6099 silc_client_del_channel_private_keys,
6100 silc_client_del_channel_private_key,
6101 silc_client_list_channel_private_keys and
6102 silc_client_free_channel_private_keys
6104 Affected file lib/silcclient/client_channel.c.
6106 * Added the support for the private keys in the channel message
6107 sending and encryption and in the message reception and
6108 decryption. Affected funtions are
6109 silc_client_send_channel_message and silc_client_channel_message.
6111 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Added SKE's key verify callback to the client library's
6114 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6116 * Removed the statement that server (or router) must send USERS
6117 command reply when joining to the channel so that the client
6118 knows who are on the channel. Instead, the client list and
6119 client's mode list is now sent in the JOIN command reply to the
6120 client who joined channel. This is better solution.
6122 * Added function silc_server_get_users_on_channel and function
6123 silc_server_save_users_on_channel to the silcd/server.[ch].
6125 * Removed function silc_server_command_send_users from the
6128 * Do not show topic on the client library anymore. The topic is
6129 sent in the command reply notify to the application and the
6130 application must show the topic now.
6132 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Added client searching by nickname hash into the IDENTIFY and
6135 WHOIS commands in the server as they were clearly missing from
6136 them. Affected file is silcd/command.c.
6138 * Fixed a bug in private message receiving in the client library.
6139 The remote ID was freed and it wasn't supposed, now it is
6142 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6144 * Minor fix to the channel payload; allocate the data area, as it
6145 needs to be of specific length.
6147 * If the key agreement port is zero then the operating
6148 system will define the bound port. Affected files are
6149 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6151 * Added new function silc_channel_payload_decrypt into the file
6152 lib/silccore/silcchannel.[ch].
6154 * Moved the channel message etc, check from silc_packet_decrypt
6155 to applications. The library calls now a generic
6156 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6157 when the packet is either normal or special. This was done to
6158 allow more wide range of checking that was not allowed when
6159 the code was in library. Now applications can do virtually any
6160 checks to the packet and return to the library the decision how
6161 the packet should be processed. Affected files are
6162 lib/silccore/silcpacket.[ch].
6164 Added silc_server_packet_decrypt_check to the server and
6165 silc_client_packet_decrypt_check to the client library.
6167 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6168 to send with specified source and destination information.
6170 * Channel message delivery between routers was broken after the
6171 channel key distribution was fixed earlier. The channel key
6172 was used be to distributed to other routers as well which is not
6173 allowed by the protocol. Now this is fixed and channel keys
6174 really are cell specific and the channel message delivery between
6175 routers comply with the protocol specification.
6177 * Fixed various commands in server to check also the global list
6178 for the channel entry and not just the local list. The affected
6179 file silcd/command.c.
6181 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Added assert()s to buffer formatting and unformatting routines
6184 to assert (if --enable-debug) when error occurs. Affected
6185 file: lib/silcutil/silcbuffmt.c.
6187 * Changed to auto-reconnect to check whether the remote host is
6188 router and register the re-connect timeout if it is. It used
6189 to check that whether we are normal server, but router must do
6190 auto-reconnect with another router as well. Affected file
6193 * Removed the [<key len>] option from CMODE command as the cipher
6194 name decides the key length, nowadays. See the defined ciphers
6195 from the protocol specification.
6197 * Added [<hmac>] option to the CMODE command to define the HMAC
6198 for the channel. Added SILC_CMODE_HMAC channel mode.
6200 * Added [<hmac>] option for the JOIN command so that user can
6201 select which HMAC is used to compute the MACs of the channel
6204 * Added Hmac field to the Channel Message Payload. The integrity
6205 of plaintext channel messages are now protected by computing
6206 MAC of the message and attaching the MAC to the payload. The
6207 MAC is encrypted. Now, it is clear that this causes some
6208 overhead to the size of the packet but rationale for this is that
6209 now the receiver can verify whether the channel message decrypted
6210 correctly and also when private keys are set for the channel the
6211 receiver can decrypt the packet with several keys and check from
6212 the MAC which key decrypted the message correctly.
6214 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6215 lib/silccrypt/silccipher.[ch].
6217 * Added silc_hash_len to return the digest length into the
6218 lib/silcrypt/silchash.[ch].
6220 * Rewrote parts of Silc Channel Payload interface in the
6221 lib/silccore/silcchannel.[ch]. The encode function now also
6222 encrypts the packet and parse function decrypts it.
6224 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Fixed a minor formatting bug in the SKE's key material processing.
6227 It actually might have processed the keys wrong way resulting
6230 * Redefined the mandatory HMAC algorithms and added new algorithms.
6231 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6232 and hmac-md5 truncated to 96 bits. The mandatory is now
6233 hmac-sha1-96. Rest are optional (including the one that used
6234 to be mandatory). Rationale for this is that the truncated HMAC
6235 length is sufficient from security point of view and can actually
6236 make the attack against the HMAC harder. Also, the truncated
6237 HMAC causes less overhead to the packets. See the RFC2104 for
6240 * Added new [hmac] configuration section. The SKE used to use
6241 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6242 is of course wrong. The official names that must be proposed in
6243 the SKE are the ones defined in the protocol specification
6244 (hmac-sha1-96 for example). The user can configure any hmac
6245 using any hash function configured in the [hash] section. At
6246 least, the mandatory must be configured.
6248 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6250 * Added HMAC list to the SKE proposal list. It has now both
6251 hash algorithm list and HMAC list. This makes the protocol
6252 incompatible with previous versions. The SKE now seems to work
6253 the way it is supposed to work, for the first time actually.
6255 * Defined plain Hash algorithms to the protocol specification.
6258 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Implemented support for key agreement packets into the server.
6261 Added functions silc_server_key_agreement and
6262 silc_server_send_key_agreement. Other than these functions,
6263 server has nothing to do with this packet.
6265 * Added support for private message key packets into the server.
6266 Added functions silc_server_private_message_key and
6267 silc_server_send_private_message_key.
6271 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6272 called in the protocol's final callback instead in the END
6273 protocol state. This makes a little more sense and in the same
6274 time in client we can use the same protocol routines for normal
6275 key exchange and to key agreement packet handling as well.
6277 * Added to both client's and server's KE protocol context the
6278 SilcSKEKeyMaterial pointer to save the key material. We will
6279 bring the key material to the protocol's final callback by doing
6280 this. The final callback must free the key material.
6282 * Added SKE's packet_send callback into client's KE protocol
6283 context so that the caller can choose what packet sending function
6284 is used. This way we can use different packet sending when
6285 doing normal SKE when doing key agreement packet handling (in
6286 the key agreement packet handling we do not want to encrypt
6289 * Implemented the responder side of the key agreement routines
6290 in the client. The client can now bind to specified port and
6291 accept incoming key negotiation. The key material is passed
6292 to the application after the protocol is over.
6294 * Implemented the processing of incoming Key Agreement packet
6295 in the client. Added function silc_client_key_agreement to
6298 * Implemented the intiator side of the key agreement routines
6299 in the client. The client can now initiate key agreement with
6300 another remote client. The key material is passed to the
6301 application after the protocol is over.
6303 * Created client_keyagr.c to include all the key agreement
6306 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6307 SILC_TASK_CALLBACK except that it is not static.
6309 * Created client_notify.c and moved the Notify packet handling
6310 from the client.[ch] into that file.
6312 * Created client_prvmsg.c and moved all private message and
6313 private message key routines from the client.[ch] into that file.
6315 * Create client_channel.c and moved all channel message and
6316 channel private key routines from the client.[ch] into that file.
6318 * Changed silc_client_get_client_by_id_resolve to resolve with
6319 WHOIS command instead of IDENTIFY command, in the file
6320 lib/silclient/idlist.c.
6322 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Implemented the SKE's responder side to the Client library.
6326 * When FAILURE is received to the protocol do not trust it
6327 blindly. Register a timeout to wait whether the remote closes
6328 the connection as it should do it, only after that process the
6329 actual failure. This was changed to both client and server.
6331 * Added client_internal.h to include some of the structures
6332 there instead of client.h in lib/silcclient/.
6334 * Added function silc_task_unregister_by_callback to unregister
6335 timeouts by the callback function.
6337 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Some "Incomplete WHOIS info" errors has been appearing on the
6340 log files. Took away the entry->userinfo check from WHOIS
6341 reply sending. The entry->userinfo is now " " if client did not
6342 provide one. I thought this was fixed earlier but something
6343 is wrong still. Let's see if the error still appears.
6345 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Fixed a minor bug in the login when the channel key is
6348 re-generated in the server. It used to generate the key in
6349 wrong order and thus caused problems in the channel traffic.
6351 * Fixed a minor bug in channel key distsribution after
6352 KICK command. The key was not sent to the router even though
6355 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Added silc_ske_process_key_material_data as generic routine
6358 to process any key material as the SILC protocol dictates. The
6359 function is used by the actual SKE library but can be used by
6360 applications as well. This relates to the private message keys
6361 and the channel private keys since they must be processed the
6362 same way the normal SILC session keys. The protocol dictates
6363 this. Affected files: lib/silcske/silcske.[ch].
6365 Added also silc_ske_free_key_material to free the
6366 SilcSKEKeyMaterial structure.
6368 * Defined silc_cipher_set_key function to set the key for
6369 cipher without using the object's method function. The affected
6370 files: lib/silccrypt/silccipher.[ch].
6372 * Implemented silc silc_client_add_private_message_key,
6373 silc_client_add_private_message_key_ske,
6374 silc_client_del_private_message_key,
6375 silc_client_list_private_message_keys and
6376 silc_client_free_private_message_keys functions in the
6379 Added functions silc_client_send_private_message_key to send
6380 the Private Message Key payload and silc_client_private_message_key
6381 to handle incoming Private Message Key payload.
6383 * Added Cipher field to the Private Message Key payload to set
6384 the cipher to be used. If ignored, the default cipher defined
6385 in the SILC protocol (aes-256-cbc) is used.
6387 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Removed lib/silcclient/ops.h file.
6391 Redefined parts of the SILC Client Library API. Created new
6392 file silcapi.h that deprecates the ops.h file and defines the
6393 published Client Library API. Defined also private message key
6394 API and channel private key API into the file.
6396 This is the file that the application must include from the
6397 SILC Client Library. Other files need not be included by
6398 the application anymore.
6400 * Added new key_agreement client operation callback and also
6401 defined the Key Agreement library API for the application.
6403 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6406 is used by clients to request key negotiation between another
6407 client in the SILC network. If the negotiation is started it
6408 is performed using the SKE protocol. The result of the
6409 negotiation, the secret key material, can be used for example
6410 as private message key.
6412 Implemented the Key Agreement payload into the files
6413 lib/silccore/silauth.[ch].
6415 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Redefined ciphers for the SILC protocol. Added some new ciphers
6418 and defined the key lengths for the algorithms. Changed the
6419 code accordingly. The default key length is now 256 bits.
6421 * Fixed SKE key distribution function silc_ske_process_key_material
6422 when the key length is more than 128 bits. The default key
6423 length in SILC is now 256 bits.
6425 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6426 to indicate unsupported algorithm.
6428 * Renamed rijndael.c to aes.c and all functions as well.
6430 * Fixed a long standing channel key setting bug in client library.
6431 Weird that it has never surfaced before.
6433 * Fixed bug in channel deletion. If the entire channel is removed
6434 then it must also delete the references of the channel entry
6435 from the client's channel list as the client's channel entry and
6436 the channel's client entry share same memory.
6438 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Implemented CONNECT and SHUTDOWN commands in the client.
6442 * Implemented CLOSE command to the client.
6444 * Added the function silc_idlist_find_server_by_name into the
6445 files silcd/idlist.[ch].
6447 Added the function silc_idlist_find_server_by_conn into the
6448 files silcd/idlist.[ch].
6450 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * DIE command was renamed to SHUTDOWN. Updated the both code
6455 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6456 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6458 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6461 * Added function silc_server_create_connection function to create
6462 connection to remote router. My server implementation actually
6463 does not allow router to connect to normal server (it expects
6464 that normal server always initiates the connection to the router)
6465 so the CONNECT command is only good for connecting to another
6468 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6471 or some other client was kicked from the channel.
6473 Implemented the handling of the notify type to both client
6476 Implemented silc_server_send_notify_kicked to send the KICKED
6477 notify. It is used to send it to the server's primary router.
6479 * Implemented the KICK command into server and client.
6481 * Added `query' argument to the silc_idlist_get_client function
6482 to indicate whether to query the client from server or not if
6485 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6486 to indicate that the client is not channel founder.
6490 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Removed the rng context from SilcPacketContext structure and
6493 changed that the packet routine uses the Global RNG API.
6495 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added support for quit message that client can "leave" on the
6498 channel when it quits the SILC. It is ditributed inside the
6499 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6501 Added silc_server_free_client_data that will take the
6502 signoff message as argument.
6504 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6506 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Updated parts of the protocol specification to keep it up
6511 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6514 payloads in one packet.
6516 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6517 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6518 use now the new List flag.
6520 * Also deprecated the following packet types: REPLACE_ID,
6521 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6523 * Added list support for Notify packet in server.
6525 * Added silc_server_send_notify_channel_change to send the
6526 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6527 the silc_server_send_replace_id.
6529 * Added silc_server_send_notify_nick_change to send the
6530 NICK_CHANGE notify type. Deprecates the function
6531 silc_server_send_replace_id.
6533 * Added silc_server_send_notify_join to send the JOIN notify type.
6534 Deprecates the function silc_server_send_new_channel_user.
6536 * Added silc_server_send_notify_leave to send LEAVE notify type.
6537 Deprecates the function silc_server_send_remove_channel_user.
6539 * Added silc_server_send_notify_cmode and
6540 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6541 types. Deprecates the silc_server_send_set_mode function.
6543 * Added SERVER_SIGNOFF notify type to indicate that server has
6544 quit. This means that all clients on the channel from that
6545 server will drop. This can be also used when netsplit happens.
6547 Deprecated REMOVE_ID packet type since it is not needed anymore
6550 Added silc_server_send_notify_server_signoff to send the
6551 SERVER_SIGNOFF notify type. Deprecates the function
6552 silc_server_send_remove_id.
6554 Added also silc_server_send_notify_signoff to send the
6555 SIGNOFF notify type.
6557 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6558 SILC protocol from this day on. Changed the protocol
6559 specification as well.
6561 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6562 notify type. It is used between routers to notify about
6563 topic changes on a channel.
6565 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6568 * Partly updated the protocol specification to comply with the
6569 changes now made. It is still though a bit outdated.
6571 * The JOIN notify type now takes one extra argument <Channel ID>.
6572 The packet used to be destined to the channel but now the
6573 JOIN type may be sent as list thus it is impossible to
6574 destine it to any specific channel. By adding this argument
6575 it is again possible.
6577 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Added CREDITS file. The CHANGES and CREDITS file will appear
6580 in the distribution as well.
6582 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6584 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6585 types in the server's silcd/packet_receive.c.
6587 * Implemented CMODE and CUMODE to work in router environment.
6589 * Fixed minor encoding and decoding buglet from the
6590 lib/silccore/silcmode.c.
6592 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6595 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6597 * Changed all SilcConfigServer* and silc_config_server* to
6598 SilcServerConfig* and silc_server_config*, respectively.
6601 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Associated the ID (client or server ID) to the Authentication
6604 Payload to avoid any possibility of forging. Updated the
6605 protocol specification and the code accordingly.
6607 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * The RSA key length is now save to the RsaKey context in the
6610 key generation process in lib/silccrypt/rsa.c. The key length
6611 is now used to figure out the maximum size of the block allowed
6612 to be encrypted/signed.
6614 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6615 is equivalent to the silc_mp_mp2bin but does not allocate any
6618 * Changed silc_mp_mp2bin API to take length argument. If it is
6619 non-zero then the buffer is allocated that large. If zero, then
6620 the size is approximated using silc_mp_sizeinbase, which however
6623 * Created Global RNG API which is global RNG that application can
6624 initialize. After initializing, any routine anywhere in the
6625 code (including library) can use RNG without allocating a new
6626 RNG object. This was done to allow this sort of use of the
6627 RNG in code that has no chance to allocate RNG object. All
6628 applications currently allocate this and many routines in the
6629 library use this. Affected file lib/silccrypt/silcrng.[ch].
6631 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6632 it to use the Global RNG API.
6634 * Defined Authentication Payload into protocol specification that
6635 is used during SILC session to authenticate entities. It is
6636 used for example by client to authenticate itself to the server
6637 to obtain server operator privileges.
6639 Implemented this payload into the lib/silccore/silcauth.[ch].
6640 Implemented also routines for public key based authentication
6641 as the new protocol specification dictates.
6643 Moved definitions of different authentication methods from
6644 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6646 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6647 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6648 silc_pkcs_verify_with_hash functions into the file
6649 lib/silccrypt/silcpkcs.[ch].
6651 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * The client entry's userinfo pointer must be always valid.
6654 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6655 will fail since it requires the userinfo. Now, the userinfo
6656 is allocated as "" if actual userinfo does not exist. Actually,
6657 it must exist and it is totally Ok to drop client connections
6658 that does not announce the userinfo. However, we will make
6659 this workaround for now.
6661 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6662 to return the remote port by socket.
6664 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6666 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6667 SILC_SERVER_PENDING_EXEC and added an new macro
6668 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6669 data or when error occurs while processing the pending command.
6671 Added new argument `destructor' into silc_server_command_pending
6672 and to the SilcServerCommandPending object. This destructor is
6673 now called after calling the pending callback or if error occurs
6674 immediately. If error occurs the actual pending callback won't
6675 be called at all - only the destructor. The destructor may be
6676 NULL if destructor is not needed.
6678 All this applies for client library code as well. Similar
6679 changes were made there as well for the pending commands.
6681 In the client, the application must now allocate the
6682 SilcClientCommandContext with the silc_client_command_alloc
6685 * Added reference counter to the SilcServerCommandContext. Added
6686 function silc_server_command_alloc and silc_server_command_dup
6689 Same type of functions added to the client library for the same
6692 * Removed the cmd_ident from IDListData away since it is now
6693 global for all connections. It is the command identifier used
6694 in command sending and with pending commands. The affected file
6697 * Added reference counter to the SilcSocketConnection objecet to
6698 indicate the usage count of the object. The object won't be
6699 freed untill the reference counter hits zero. Currently only
6700 server uses this, and client ignores it. The client must be
6701 set to use this too later. The affected files are
6702 lib/silccore/silcsockconn.[ch]. Added also the function
6703 silc_socket_dup to increase the reference counter.
6705 This was mainly added because it is possible that the socket
6706 is removed underneath of pending command or other async
6707 operation. Now it won't be free'd and proper DISCONNECTING
6708 flags, etc. can be set to avoid sending data to connection that
6709 is not valid anymore.
6711 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6712 the connection. After that it sets SILC_SET_DISCONNECTED.
6713 It is, however, possible that the socket data is not still freed.
6714 The silc_server_packet_process now checks that data is not
6715 read or written to connection that is DISCONNECTED. The socket
6716 get's freed when the reference counter hits zero.
6718 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Changed the client operation API: channel_message operation's
6721 `sender' is now the client entry of the sender, not the nickname
6722 and the `channel' is the channel entry, not the channel name.
6724 In the private_message operation the `sender' is now also the
6725 client entry of the sender not the nickname.
6727 Affected file is lib/silcclient/ops.h and all applications
6728 using the client operations.
6730 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Moved the calling of ops->connect() from connect_to_server_final
6733 into receive_new_id functin since that is the point when the
6734 client is actually allowed to send traffic to network. The
6735 affected file is lib/silcclient/client.c.
6737 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6740 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6741 (if needs broadcasting) instead of broadcasting the packets one
6742 by one which would make a burst in the network traffic.
6744 * Added `broadcast' argument to the functions in silcd/server.[ch]
6745 silc_server_create_new_channel[_with_id] to indicate whether
6746 to send New Channel packet to primary router.
6748 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6750 * Added new function into the silcd/server.[ch] files:
6751 silc_server_create_new_channel_with_id to create new channel with
6752 already existing Channel ID.
6754 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6755 lib/silccore/silcpacket.h. This packet is used t send list of
6756 Set Mode payloads inside one packet. Server uses this to set
6757 the modes for the channels and clients on those channels, that it
6758 announced to the router when it connected to it. The protocol
6759 specification has been updated accordingly.
6761 * The silc_server_new_channel did not handle the packet coming
6762 from normal server as it normally does not send that. However,
6763 when it announces its channels it does send it. Implemented
6764 the support for that.
6766 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6767 into the file lib/silccore/id.h.
6769 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Fixed memory leaks in the functions silc_idlist_del_client,
6772 silc_idlist_del_channel and silc_idlist_del_server in the file
6773 silcd/idlist.c. All of those leaked like a sieve.
6775 * Fixed some small memory leaks in the client's function
6776 silc_client_notify_by_server.
6778 * Added functions into silcd/server.c: silc_server_announce_clients,
6779 silc_server_announce_channels and silc_server_announce_server.
6780 These functions are used by normal and router server to announce
6781 to its primary router about clients, channels and servers (when
6782 router) that we own. This is done after we've connected to the
6785 These functions effectively implements the following packet types:
6786 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6787 and SILC_PACKET_NEW_ID_LIST.
6789 * Added new functions into the silcd/packet_receive.[ch]:
6790 silc_server_new_id_list, silc_server_new_channel_list and
6791 silc_server_new_channel_user_list to handle the incoming
6792 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6794 * Added support of changing Channel ID in the function
6795 silc_server_replace_id. If the server that announces a channel
6796 to the router already exists in the router (with same name but
6797 with different Channel ID), router is responsible to send
6798 Replace ID packet to the server and force the server to change
6799 the Channel ID to the one router has.
6801 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6802 client that the Channel ID has been changed by the router. The
6803 normal server sends this to the client. Client must start using
6804 the new Channel ID as the channel's ID.
6806 Implemented handling of this new type into lib/silcclient/client.c
6807 into the function silc_client_notify_by_server.
6809 * Added new function silc_idlist_replace_channel_id into the files
6810 silcd/idlist.[ch] to replace the Channel ID.
6812 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Call silc_server_command_identify_check always when processing
6815 the IDENTIFY command in silcd/command.c
6817 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6819 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6820 send keepalive packets. The packet can be sent by clients,
6821 servers and routers.
6823 Added function silc_socket_set_heartbeat into the file
6824 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6825 If not set, the heartbeat is not performed. The actual
6826 heartbeat is implemented in the low level socket connection
6827 library. However, application is responsible of actually
6830 Added silc_server_send_heartbeat to send the actual heartbeat
6831 packet into silcd/packet_send.[ch]. Server now performs
6832 keepalive with all connections.
6834 * Added silc_task_get_first function into lib/silcutil/silctask.c
6835 to return the timeout task with shortest timeout. There was a bug
6836 in task unregistration that caused problems. TODO has been
6837 updated to include that task system must be rewritten.
6839 * The client library will now resolve the client information when
6840 receiving JOIN notify from server for client that we know but
6841 have incomplete information.
6843 * Rewrote parts of silc_server_remove_from_channels and
6844 silc_server_remove_from_one_channel as they did not remove the
6845 channel in some circumstances even though they should've.
6847 * Encryption problem encountered in server:
6849 The LEAVE command used to send the Channel Key packet to the
6850 router immediately after generating it. However, the code
6851 had earlier sent Remove Channel user packet but not immediately,
6852 ie. it was put to queue. The order of packets in the router
6853 was that Channel Key packet was first and Remove Channel User
6854 packet was second, even though they were encrypted in the
6855 reverse order. For this reason, MAC check failed. Now, this
6856 is fixed by not sending the Channel Key packet immediately but
6857 putting it to queue. However, this is more fundamental problem:
6858 packets that are in queue should actually not be encrypted
6859 because packets that are sent immediately gets encrypted
6860 actually with wrong IV (and thus MAC check fails). So, packets
6861 that are in queue should be encrypted when they are sent to
6862 the wire and not when they put to the queue.
6864 However, the problem is that the current system has not been
6865 designed to work that way. Instead, the packet is encrypted
6866 as soon as possible and left to the queue. The queue is then
6867 just purged into wire. There won't be any fixes for this
6868 any time soon. So, the current semantic for packet sending
6871 o If you send packet to remote host and do not force the send
6872 (the packet will be in queue) then all subsequent packets to the
6873 same remote host must also be put to the queue. Only after the
6874 queue has been purged is it safe again to force the packet
6877 o If you send all packets immediately then it safe to send
6878 any of subsequent packets through the queue, however, after
6879 the first packet is put to queue then any subsequent packets
6880 must also be put to the queue.
6882 Follow these rules and everything works fine.
6884 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6886 * Added new function silc_server_remove_clients_by_server to
6887 remove all client entries from ID list when the server connection
6888 is lost. In this case it is also important to invalidate all
6889 client entires as they hold the invalid server entry. This
6890 fixes fatal bug when server has lost connection and will reconnect
6893 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Made some sanity checks to silc_server_daemonise like to check
6896 whether the requested user and group actually exists.
6898 * Added sanity check to SKE's silc_ske_responder_finish to check
6899 that the public and private key actually is valid.
6901 * Invalidate the client's nickname when receiving Replace ID
6902 packet and the Client ID is being replaced. This means that the
6903 server will query the nickname if someone needs it (client)
6906 * Sort the ID Cache in client library when the ID Cache data
6907 has changed (needs sorting).
6909 * Do not allow for SILC client to create several connections to
6910 several servers. The client does not support windows right now
6911 and generating multiple connections causes weird behaviour.
6913 Irssi-silc client does support windows and can handle several
6914 connections without problems, see: www.irssi.org and SILC plugin.
6916 * Fixed some places where client was added to the IDList. The
6917 rule of thumb is following (in order to get everything right):
6918 If the client is directly connected local client then the
6919 `connection' argument must be set and `router' argument must be
6920 NULL to silc_idlist_add_client function. If the client is not
6921 directly connected client then the `router' argument must
6922 bet set and the `connection' argument must be NULL to the
6923 silc_idlist_add_client function.
6925 * The funtion silc_server_packet_send_local_channel actually did
6926 not check whether the client was locally connected or not. It
6927 does that now. Fixed a bug related to LEAVE command.
6929 * Fixed Remove Channel User payload parsing bug in server's
6930 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6932 * The server's silc_server_save_channel_key now checks also the
6933 global ID list for the channel as it might not be in the local
6934 list. Fixed a bug related to LEAVE command.
6936 * Is this the end of the [<unknown>] buglet that has been lurking
6937 around for a long time? A little for loop fix in server's
6938 silc_server_command_whois_parse that is used by both IDENTIFY
6939 and WHOIS command. At least, this was a clear bug and a cause
6940 of one type of [<unknown>] buglet.
6942 * WHOIS and IDENTIFY commands call the function
6943 silc_server_command_[whois/identify]_check function even if
6944 we are not router server.
6946 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6948 * Added --with-gmp configuration option. If set the GMP
6949 is always compiled in the SILC source tree. If not set then
6950 it is checked whether the system has the GMP3 installed. If
6951 it has then the GMP won't be compiled (the system's headers
6952 and library is used), if it doesn't have it then the GMP is
6953 compiled in the SILC source tree.
6955 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6957 * Changed RSA private exponent generation to what PKCS #1
6958 suggests. We try to find the smallest possible d by doing
6959 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6960 not security fix but optimization.
6962 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6964 * Added new config entry [Identity] to fork the server and run
6965 it as specific user and group. A patch from Bostik.
6967 * Imported Dotconf configuration library into lib/dotconf.
6968 This will be used to create the SILC configuration files later.
6969 It will appear in the distsribution after this commit.
6971 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6973 * A big code auditing weekend happening. Auditing code for
6974 obvious mistakes, bugs and errors. Also, removing any code
6977 Removed files for being obsolete:
6979 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6980 inline in the file lib/silcutil/silcbuffer.h)
6982 o lib/silcutil/silcbufutil.c (the header has inline versions)
6984 Changed code to fix possible error conditions:
6986 o The buffer formatting routines now check that the destination
6987 buffer really has enough space to add the data. This applies for
6988 both buffer formatting and unformatting
6989 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6990 unformatting was changed to accomodate following rules:
6991 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6992 sent to the function while XXX_*STRING will not allocate or copy
6993 the data into the buffer. Instead it sets the pointer from the
6994 buffer into the pointer sent as argument (XXX_*STRING used to
6995 require that the pointer must be allocated already). This change
6996 makes this whole thing a bit more consistent and more optimized
6997 (note that the data returned in the unformatting with XXX_*STRING
6998 must not be freed now). The routines return now -1 on error.
7000 o Tried to find all code that use buffer_format and buffer_unformat
7001 and added return value checking to prevent formatting and
7002 especially unformatting errors and possible subsequent fatal
7005 o Changed ske->x and ske->KEY to mallocated pointers in
7006 lib/silcske/silcske.h. Fixed possible data and memory leak.
7008 o Added return value checking to all *_parse* functions. Fixed
7009 many memory leaks as well.
7011 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7012 so that buffer overflows would not happen. All code now also
7013 checks the return value as it can fail.
7015 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Added reconnection support to server if the normal server looses
7018 its connection to the router (for example if router is rebooted).
7019 The server performs normal reconnection strategy implemented
7020 to the server. Affected file silcd/server.c.
7022 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Added new packet type SILC_PACKET_SET_MODE that is used to
7025 distribute the information about changed modes (for clients,
7026 channels and clients channel modes) to all routers in the
7027 network. Updated the protocol specification accordingly.
7029 Added functions into silcd/packet_send.c and
7030 silcd/packet_receive.c: silc_server_send_set_mode,
7031 silc_server_set_mode.
7033 Added new files silcmode.[ch] into lib/silccore that implements
7034 the encoding and decoding of Set Mode Payload. Added new type
7035 SilcSetModePayload. Moved the definitions of different modes
7036 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7038 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7040 * Oops, a little mistake in server's connection authentication
7041 protocol. The protocol is not ended with FAILURE but with
7042 SUCCESS if the authentication is Ok. :) Affected file is
7045 * Implemented NICK_CHANGE notify handling in server in the file
7046 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7047 the local clients on the channel. After the changing nickname
7048 in router environment snhould work and the [<unknown>] nickname
7049 should appear no more.
7051 The silc_server_replace_id function that receives the Replace ID
7052 payload now sends the NICK_CHANGE notify type also in the file
7053 silcd/packet_receive.c
7055 * Changed WHOIS and IDENTIFY command to support the maximum amount
7056 of arguments defined in protocol specs (3328 arguments). This
7057 fixed a bug that caused problems when there were more than three
7060 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * Added extra parameter, command identifier, to the
7063 silc_client_send_command so that explicit command identifier
7066 Changed that ID list routines uses specific command identifier
7067 when sending WHOIS/IDENTIFY requests to the server so that they
7068 can be identified when the reply comes back.
7070 Affected files lib/silcclient/command.[ch],
7071 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7073 * Added `sender' argument to silc_server_packet_send_to_channel
7074 to indicaet the sender who originally sent the packet to us
7075 that we are now re-sending. Ignored if NULL. Affected file
7076 silcd/packet_send.[ch].
7078 * Added some server statistics support in silcd/server_internal.h
7079 SilcServerStatistics structure and around the server code. Also
7080 send some nice statistics information when client is connecting
7083 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Fixed channel ID decoding in server's JOIN command reply in
7086 silcd/command_reply.c
7088 * Fixed braodcasting of replace ID payload to not to send it if
7089 we are standalone server in silcd/packet_receive.c.
7091 * Fixed all channel message sending routines to not to send
7092 packets to clients that has router set, since they are routed
7093 separately in the same function earlier. Affects file
7094 silcd/packet_send.c and all channel packet sending functions.
7096 * In USERS reply, res_argv[i] are not allocated, the table
7097 is allocated. Thus changed that free the table, not its
7100 * In server's whois_check and identify_check if the client is
7101 locally connected do not send any WHOIS commands - they are not
7104 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7106 * Fixed some minor bugs in client when sending WHOIS command. The
7107 arguments was in wrong order.
7109 * Removed statis function add_to_channel from server in
7110 silcd/command.c that was previously used with the joining but
7113 * Tested USERS command in router environment successfully with two
7114 routers, two servers and two clients.
7116 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Reorganized the USERS command and command reply in client library
7119 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7120 When the command is given by user we register a pending command
7121 callback that will reprocess the command after the reply has been
7122 received from the server. When reprocessing the packet we then
7123 display the information. Thus, the USERS information is displayed
7124 now in the command callback instead of in the command reply
7125 callback. The processing of the command is same as previously
7126 when server has sent the command reply in the JOINing process.
7128 * Added to USERS command in silcd/command_reply.c to join the client,
7129 we didn't use to know about, to the channel after we've created
7130 a client entry for it. Also, for clienet we did know already still
7131 check whether it is on the channel or not and add it if not.
7133 * Removed silc_server_command_join_notify as the function and its
7136 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Changed the client's pending command handling to the same as the
7139 server's pending command handling. It is also now possible to
7140 execute command reply functions from other command reply
7141 function as the function callbacks for commands and command
7142 replies are one and same. The pending commands are not static
7143 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7144 in client connection context. Thus, pending commands are server
7145 connection specific as it is convenient.
7147 Changed the function silc_client_command_pending and
7148 silc_client_command_pending_del and added new function
7149 silc_client_command_pending_check. Removed the
7150 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7153 * Added cmd_ident, current command identifier, to the client
7154 connection context in lib/silcclient/client.h to keep track on
7155 command identifiers used in command sending. Client's command reply
7156 function handling now supports the mandatory command identifiers.
7158 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7159 funtions in client to fully support pending command callbacks.
7161 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7162 as one of the arguments to the application in the command reply
7165 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7166 before first releasing SILC but came back. Now it is removed again
7167 and should come back nomore. The FORWARDED flag was used only
7168 by the JOINing procedure by forwarding the command packet to router.
7169 Now, the JOINing procedure has been changed to more generic (due
7170 to various router environment issues) and FORWARDED is not needed
7171 anymore for anything. The protocol specification is yet to be
7174 Now, removed silc_server_packet_forward from server and the flag
7175 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7177 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Renamed NAMES command to USERS command. The NAMES was named that
7180 due to historical reasons. Now it is renamed. Also, rewrote
7181 parts of the USERS command. The nickname list is not sent anymore
7182 by the server. Only Client ID and mode lists are sent in the USERS
7183 command. Changed this also to the protocol specification.
7185 The client now resolves the names and stuff after it receives
7186 the USERS list from the server when joining to the channel.
7188 * WHOIS and IDENTIFY commands has been changed to support multiple
7189 Client ID's per command. One can now search for multiple users
7190 in the network by sending only one WHOIS or IDENTIFY command.
7191 Changed the code and the protocol specifications.
7193 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7194 uses silc_server_command_whois_parse to parse the request. */
7196 * If normal server, do not parse the WHOIS and IDENTIFY requests
7197 before sending it to the router. Saves some time.
7199 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7201 * Fixed JOIN command on client library. Wrong number of arguments
7202 used to crash the client.
7204 * Added silc_server_channel_has_global function to check whether
7205 channel has global users or not.
7207 * Added silc_server_channel_has_local function to check whether channel
7208 has locally connected clients on the channel.
7210 * The silc_server_remove_from_one_channel now checks whether the
7211 channel has global users or not after given client was removed from
7212 the channel. It also checks whether the channel has local clients
7213 on the channel anymore. If it does not have then the channel entry
7214 is removed as it is not needed anymore.
7216 * The silc_server_notify now checks on JOIN notify whether the joining
7217 client is one of locally connected or global. If it is global then
7218 the channel has now global users on the channel and that is marked
7219 to the channel entry. Also, it now saves the global client to
7220 global list who is joining and JOINs it to the channel. This is
7221 for normal server, that is.
7223 Changed silc_server_send_notify_on_channel,
7224 silc_server_packet_relay_to_channel and
7225 silc_server_packet_send_to_channel check if we are normal server
7226 and client has router set (ie. global client) do not send the
7227 message to that client, as it is already routed to our router.
7229 * Implemented LEAVE notify type handling in silc_server_notify
7232 * Tested LEAVE command in router environment successfully. Tested
7233 with two routers, two servers and two clients.
7237 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7239 * Implemented SIGNOFF notify type handling in silc_server_notify
7242 * silc_server_remove_id now removes the client entry from all channels
7243 it has joined and thusly sends SIGNOFF notify type.
7245 * Rewrote the NAMES list generation in server by removing two excess
7246 loops. The lists are created now inside one loop.
7248 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * silc_server_remove_channel_user checks now also global list
7251 for channel and client.
7253 * silc_server_new_channel_user checks now both local and global
7254 list for channel and client. Fixed a bug in client id decoding.
7255 Used to decode wrong buffer.
7257 * silc_server_channel_message checks now both local and global
7258 list for channel entry.
7260 * Tested channel joining (hence JOIN) in router environment
7261 successfully. Tested with two routers, two servers and two
7264 * Tested channel message sending in router environment successfully.
7266 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7268 * Added silc_server_save_channel_key into server.[ch] to save the
7269 received channel key in Channel Key payload processing. It is
7270 also used in JOIN command reply handling.
7272 Equivalent function silc_client_save_channel_key added into
7273 client.[ch] into client library.
7275 * Changed JOIN command reply to send information whether the channel
7276 was created or not (is existing already) and the channel key
7277 payload. Changed protocol specs accordingly.
7279 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7280 the request was sent by ID and not by nickname. Crashed on
7283 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7286 now correctly save the received data.
7288 * silc_server_free_sock_user_data now notifies routers in the
7289 network about entities leaving the network.
7291 At the same time implemented functions silc_server_remove_id
7292 and silc_server_send_remove_id to receive and send REMOVE_ID
7293 packets. The packet is used to notify routers in the network
7294 about leaving entities. The ID removed will become invalid in
7297 * Added function silc_idlist_del_server into server. Removes and
7298 free's server entry from ID list.
7300 * silc_server_private_message function now checks, if we are router,
7301 that the destination ID really is valid ID, naturally.
7303 * In router when NEW_ID packet is received (for new client) the
7304 hash of the Client ID is saved in the ID Cache but the
7305 client->nickname is set to NULL, instead of putting the hash
7308 IDENTIFY command now also checks that client->nickname must be
7309 valid. If it is not if will request the data from the server who
7310 owns the client. Added new function
7311 silc_server_command_identify_check.
7313 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7314 to set the command to already allocated Command Payload.
7316 * Tested private message sending in router environment with two
7317 routers, two servers and two clients. Fixed minor bugs and now
7320 * Fixed segfault from client's NAMES command. Used to crash if
7323 * Forwarded packets must not be routed even if it is not destined
7324 to the receiver. Changed server code comply with this.
7326 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added `require_reverse_mapping' boolean value to ServerParams
7329 structure. If TRUE (not default) the server will require that
7330 the connecting host has fully qualified domain name.
7332 If the reverse mapping is not required and hostname could not be
7333 found the IP address is used as hostname.
7335 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7337 * Implemented version string checking to both client and server.
7338 The check is incomplete currently due to the abnormal version
7339 strings used in development version of SILC.
7341 * Changed all command functions in server to use the new
7344 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * Changed char *data to unsigned char *data in ID Cache system to
7347 support binary data as ID Cache data. Changed code to support
7348 binary data in lib/silccore/idcache.c.
7350 * Renamed silc_server_packet_relay_command_reply to
7351 silc_server_command_reply as it is normal packet receiving
7352 function. Rewrote the function to accept command replys for
7353 servers and not only for clients.
7355 * Mark remote router always as registered server if we are connecting
7356 to it. Otherwise, commands sent by the router to us are ignored.
7358 * All ID List find routines now returns the ID Cache Entry pointer
7359 as well if requested.
7361 * WHOIS command works now in router environment, tested with two
7362 routers, two servers and two clients.
7364 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7365 in router environment (as it is almost equivalent to WHOIS) but
7366 hasn't been tested thoroughly. Added new functions:
7368 silc_server_command_identify_parse
7369 silc_server_command_identify_send_reply
7370 silc_server_command_identify_from_client
7371 silc_server_command_identify_from_server
7373 * Disabled route cache adding because adding two different ID's with
7374 same IP replaces the old cache entry thus giving wrong route.
7375 The entry->router->connection is always the fastest route anyway
7376 so route cache may not be needed. Of course, new routes maybe
7377 established after receiving the ID when the entry->router->connection
7378 might not be anymore the most optimal.
7380 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Add route cache for received ID for fast routing.
7384 * Added silc_server_packet_route to route received packet on router
7385 that is not destined to us.
7387 * Renamed silc_server_get_route to silc_server_route_get.
7389 * Added id_string and id_string_len fields into SilcServer to
7390 include encoded ServerID for fast comparing without excess
7391 encoding of the ID's.
7393 * Cleaned up WHOIS command on server side. Added following static
7396 silc_server_command_whois_parse
7397 silc_server_command_whois_check
7398 silc_server_command_whois_send_reply
7399 silc_server_command_whois_from_client
7400 silc_server_command_whois_from_server
7402 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7403 arguments in command replies. All command functions should be
7404 updated to use this macro.
7406 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Minor typo fixes on command reply handling on server.
7410 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Added silc_server_command_add_to_channel internal routine to add
7413 the client to the channel after router has created the channel and
7414 sent command reply to the server.
7416 * Added generic silc_server_send_command to send any command from
7419 * Use static buffer with ID rendering instead of duplicating data.
7421 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7423 * Fixed a channel user mode bug when joining to a channel server gave
7424 everybody channel founder rights, oops.
7426 * We mark ourselves as the router of the incoming server connection
7427 if we are router ourselves. This way we can check in some packet
7428 sending functions whether it is locally connected server. For
7429 incoming router connections we put NULL.
7431 * For router sending packets locally means now always sending the
7432 packet cell wide; to local clients and local servers. For normal
7433 server sending packet locally means sending it to only local
7436 * Fixed the JOIN command to really work in router environment. If the
7437 channel is created it is always created by the router. Router is
7438 also responsible of making the initial joining to the channel,
7439 sending JOIN notify to the sending server and distributing
7440 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7441 does not exist server doesn't do anything else but forward the
7442 command to the router which performs everything.
7444 * Added silc_server_send_channel_key function to send the Channel Key
7447 * Added silc_server_create_channel_key to create new channel key. The
7448 channel key is now re-generated everytime someone joins or leaves
7449 a channel, as protocol dictates. Note: channel->key_len is the
7452 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7455 packet_receive.[ch] to separate packet sending and receiving
7456 routines. The server.[ch] now includes everything else including
7457 actual packet processing (writing and reading data) and other
7460 Renamed silc_server_private_message_send_internal to
7461 silc_server_send_private_message. The routine is still though
7462 used only to relay private messages as server does not send
7463 private messages itself.
7465 Renamed silc_server_new_channel to silc_server_create_new_channel
7466 and added new function sicl_server_new_channel that handles the
7467 incoming New Channel packet. Added also new sending function
7468 silc_server_send_new_channel to send New Channel Payload.
7470 * Added new function silc_server_notify to process incoming notify
7471 packet to the server/router. Server may then relay the notify
7472 to clients if needed.
7474 * Added new function silc_server_new_channel_user to process incoming
7475 New Channel User packet. Router will redistribute the packet and
7476 send JOIN notify to its local clients and locally connected servers
7477 if needed. Normal server will send JOIN notify to its local client
7478 on same channel when received this packet. Added also corresponding
7479 sending function silc_server_send_new_channel_user to sent the
7482 * Added boolean route argument to send_notif_to_channel and
7483 packet_send_to_channel functions to attempt to route the packet
7484 if it is TRUE and send only locally if it is FALSE.
7486 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7488 * silc_server_replace_id now broadcasts the received replace ID
7489 packet if it is not broadcast packet already. The router must
7490 broadcast to inform other routers about changed ID.
7492 * Added backpointer to server's router into SilcServer context in
7493 silcd/server_internal.h.
7495 * Fixed silc_server_packet_broadcast to send correct broadcast
7498 * The channel key is now distributed to the local client as soon
7499 as it is received from the router (in router environment) so that
7500 no other packet may be sent for the channel until client has
7503 * silc_server_remove_channel_user now broadcasts the received
7504 Remove Channel User packet if it is not broadcast packet already.
7505 The router must broadcast to inform other routers about removed
7508 * Added users field into SilcPacketContext that is a reference count
7509 of the context. One can increase the reference count by calling
7510 silc_packet_context_dup which is now changed to just increase the
7511 reference count instead of duplicating the data. The reference
7512 count is decresed by calling silc_packet_context_free that will
7513 free the data after the reference count hits zero.
7515 For now on the packet context and everything allocated into it
7516 (including the raw packet from network) must be freed by calling
7517 the new silc_packet_context_free function. Added also new function
7518 silc_packet_context_alloc that must be used now to allocate the
7519 context. This also means that if a routine is asynchronous from
7520 silc_[client/server]_packet_parse_type the packet context must
7521 be duplicated by calling silc_packet_context_dup. Otherwise it
7522 gets free'd after silc_[client/server]_packet_parse_type returns.
7523 Also, one must remember that if packet is duplicated then its
7524 reference count must be decresed by calling the free function as
7525 many times as it was duplicated.
7527 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7528 from both client and server.
7530 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Made joining to a channel working in router environment.
7534 * Cleaned up JOIN command on server side and create function
7535 silc_server_command_join_channel internal routine to make the
7538 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Changed silc_command_pending list to SilcDList. Also, added
7541 `ident' field to SilcServerCommandPending structure to identify
7542 the reply and to call correct callback.
7544 Added silc_server_command_pending_check function to replace the
7545 corresnponding macro. The silc_command_pending list is not
7548 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7549 to set identifier to previously allocated Command Payload. It
7550 is used to set identifier for command when resending Command
7553 * Added silc_command_payload_encode_payload to encode Command
7554 Payload buffer from SilcCommandPayload structure.
7556 * Added silc_argument_payload_encode_payload to encode Argument
7557 payload buffer from SilcArgumentPayload structure.
7559 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Changed WHOIS command to support router connection on server side.
7562 The whois request is always sent to router unless the server is
7563 standalone server. After server has received the reply from the
7564 router will it send the reply to the client.
7566 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7567 broadcast received broadcast packet. The function is used only
7568 by router. The broadcast packet is always sent to the router's
7571 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7572 render given ID to printable string, for log files for example.
7574 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7576 * Made basic router to router connections working. At least they
7577 can now connect to each other but nothing really works the way
7578 they are supposed - yet.
7580 * Added new initiator token to RouterConnection configuration
7581 file in silcd/serverconfig.[ch]. It is used to tell whether we
7582 are the initiator to the remote router or whether we'll expect
7583 the other end to connect.
7585 * Moved registering of listener task to silc_server_init, hence
7586 the server starts listenning as soon as it is run, even if it
7587 does not have connections to other routers. Let's see how well
7590 * Changed default connection retry timeouts for more suitable in
7593 * Removed cipher and such arguments from silc_idlist_add_client
7594 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7595 Added new function silc_idlist_add_data to add the keys and stuff
7598 * Added SilcIDListData structure and added it to SilcClientEntry
7599 and SilcServerEntry as their first field in the structure. This
7600 way we can explicitly cast the ID entries to the SilcIDListData
7601 structure and get common data for the entries. In past, we had
7602 to first check what type of connection it is and then cast it to
7603 correct ID entry type. Now, we can directly cast the opaque
7604 pointer to the SilcIDListData (no matter what ID entry it actually
7605 is) and get the data needed.
7607 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7610 in some circumstances even if threre were timeout tasks, though not
7611 IO tasks, but tasks anyway. Now fixed.
7613 * Defined SilcServerConnection structure to hold connection specific
7614 stuff about directly connected servers and routers. The definition
7615 is currently in silcd/server_internal.h. I thought about having
7616 a bit more important role fro this struct but for now it is used
7617 only when connecting to other server (or router actually).
7619 * Added connecting retry support in server when connecting to
7620 router(s). The retry feature implement exponential backoff
7621 algorithm. Also, added SilcServerParams structure to hold default
7622 parameters for server. For now, it include these retry settings
7623 and are hard coded. After server is moded to be as Silc Server
7624 Library this structure will be more important.
7626 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Changed client librarys channel->clients table to SilcList and
7629 changed code accordingly.
7631 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7633 * Changed client's channel table to SilcList and changed code
7634 accordingly. Also changed SilcChannelClientEntry to include back-
7635 pointer to the channel so that client entry can use that structure
7636 as list as well and we have fast cross-reference to the channel.
7637 This change dramatically decreased the complexity of channel
7638 handling with client entry and vice versa (removed one extra
7639 loop when searching for channel entry from many functions).
7641 * Changed server->sim from table to SilcDList and changed code
7644 * NAMES command can now be used from user interface. It will show
7645 the user list on the channel, neatly.
7647 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7648 Code now saves realname of the user if it becomes available.
7650 * Renamed configure.in to configure.in.pre and made ./prepare
7651 script to automatically add correct version string to
7652 configure.in which it creates from configure.in.pre.
7654 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7656 * NAMES command reply now shows users mode with the nickname when
7659 * Moved silc_client_ch[u]mode[_char] functions from
7660 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7661 place sucks, they are utility functions and should be in some
7664 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7666 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7669 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Added TRQ (efficient deque and list library) into lib/trq. This is
7674 a very good list library that is currently used in the SILC. Defined
7675 SilcList API over the library because I didn't like the API very
7676 much. See lib/trq/silclist.h for the API and examples of how to
7677 use the API. Fixed various places in the code to use the new
7678 SilcList API. The SilcList is meant for lists that has a structure
7679 already defined as a list. It is not suitable to add just some
7680 context to the list (in TRQ, the context is the list actually).
7682 So, I defined SilcDList that can be used for the purpose where
7683 predefined list structure does not exit. This can be used as
7684 such list. Now some context just can be added to the SilcDList.
7685 Currently this list is not used in the SILC just yet, though there
7686 are a lot places where this can replace dynamically allocated
7687 tables and I will fix these places, later, to use SilcDList.
7688 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7689 and use TRQ internally).
7691 Also fixed some annoying warning messages that the original TRQ
7692 code generated. Also minor changes to TRQ's Makefile.in.
7694 * Added support for querying by Client ID to both WHOIS and
7695 IDENTIFY commands into server, as required by the protocol.
7697 * Removed method function pointers from SilcBuffer structure. They
7698 weren't used to anything and just increased the context size for
7699 no good reason. This change also made silc_buffer_alloc and
7700 silc_buffer_free functions inline functions.
7702 * Disabled command flooding detection support until it's fixed so
7703 that it accepts commands in but does not execute them more than once
7706 * Added silc_net_localhost(), to return local hostname, into
7707 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7708 that must be initialized before calling silc_client_init.
7710 * Added new function: silc_server_send_notify_on_channels to send
7711 notify messages to all channels client has joined. It is assured
7712 that the message is sent only once per client.
7714 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7715 lib/silcutil/silcutil.[ch] as silc_format function. The new
7716 function is generic and is used by server as well, not only by
7717 the logging routines.
7719 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7720 the provided version string was not acceptable. Added new function:
7721 silc_ske_check_version into lib/silcske/silcske.h. The function
7722 must be implemented by the application (client or server) and it
7723 does not reside in the SKE library. The function checks the version
7724 string remote end sent.
7726 * Added back pointers (to opaque context and to SilcSocketConnection)
7727 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7729 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7730 duplicate packet context structure.
7732 * Changed `notify' client operation to send same arguments as client
7733 receives from server except for ID's. ID's are mapped to correct
7734 ID entry and that is returned. Also, if channel entry is not sent
7735 by server but the notify is for channel the channel entry is sent
7736 to application (otherwise application doesn't know that it is for
7737 channel (library gets it from packet's Destination ID)).
7739 * Added silc_client_remove_from_channels into client library to
7740 remove a client from all channels it has joined to. Used when
7741 received SIGNOFF notify from server. Added also new function
7742 silc_client_replace_from_channels to replace old ID entry with
7743 new ID entry on all channels. Used when received NICK_CHANGE
7746 * Fixed ID Cache list handling in silc_idlist_get_client in
7747 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7748 to get (or query) client by ID.
7750 * Updated TODO list.
7752 * Added connection authentication status message defined by the
7753 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7754 support for these into the code in client and server side.
7756 * Added generic function silc_client_send_command to send any command
7757 with variable argument list. Application should use this function
7758 to send commands if the command functions provided by the library
7759 does not suite for the application's user interface needs.
7761 * Added new `failure' client operation. Application is notified about
7762 received failure packet if client is executing a protocol. In this
7763 case the protocol's execution has failed.
7765 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7766 is required by the protocol.
7768 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7769 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7772 * Added status flag to SilcSKE object to indicate realtime status
7773 of the SKE protocol.
7775 * Application receives now exactly same command reply arguments as
7776 the library receives from server. However, if ID is received the
7777 corresponding ID entry is returned to the application (eg. Client
7778 ID is mapped to correct SilcClientEntry entry and that is returned).
7779 Changed command_reply client operation due to this change.
7781 * Changed all ID's in commands and in command replys as ID Payloads.
7782 Change affected both client and server side codes.
7784 All ID's sent in SILC network (with execption of ID's in SILC
7785 Packet header) are sent in ID Payload to support variable length
7788 * Server now notifies nick changes and notifies all clients on
7789 the channels about the new nickname (about the new Client ID,
7792 * Implemented CMODE command to change channel modes. Supports all
7793 channel modes defined by the protocol specs except ban and invite
7794 lists. (Also, private channel key mode is supported but support for
7795 setting private channel key in client is missing, thus, this mode
7796 has no effect on client side (except that server requires that the
7797 client uses private channel key and normal channel traffic does not
7800 Also, invite mode works per se, but INVITE command does not work
7801 yet correctly, so you can set channel as invite only channel but
7802 inviting clients to the channel does not work (it is yet to be
7803 thought what's the best way to do it).
7805 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7806 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7807 Implemented CUMODE command to change user's mode on the channel.
7808 Supports all modes defined by the protocol specs.
7810 * Added NAMES command reply to return users modes on the channel.
7812 * Removed unnecessary and slow ciphers from lib/silccrypt.
7814 * Set SO_KEEPALIVE option to connection sockets by default.
7816 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7818 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7819 redefined the Notify Payload into protocol specs.
7821 * Added silc_id_payload_parse_id to get ID directly from raw
7824 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7826 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7827 accept searching by Client ID as well.
7829 * Added support for LEAVE and SIGNOFF notify types in client library.
7831 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7832 to parse ID Payload from raw data.
7834 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7836 * Added flags parameter into silc_ske_assemble_security_properties
7837 function in lib/silcske/silcske.[ch].
7839 * Changed notify client operation to fit better for notify messages
7840 sent by server. The notify payload received from server is now
7841 passed to the application (after parsing it to SilcNotifyPayload).
7842 It is application's responsibility to retrieve the arguments
7843 from the payload and show the message the way it wants. The message
7844 sent by server is implementation specific.
7846 * Changed public keys to comply with the protocol specification.
7847 Old public keys are not supported anymore and are not compatible.
7849 * Removed nickname from Channel Payload as the latest draft removed
7850 it. The client must resolve the nickname from the NAMES command
7851 reply received when it joined the channel.
7853 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7855 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7857 * Fixed some errors in protocol specification drafts.
7859 * Created lib/silccore/silcnotify.c to implement Notify Payload
7860 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7861 generic payloads described by protocol specifications. The file
7862 includes implementations for ID Payload and Argument Payload.
7864 * Changed Command Payload implementation to use the new Argument
7865 Payload. Changed command_xxxx_payload to command_payload_xxxx
7866 to comply with SILC coding conventions.
7868 * Added suppport for Argument Payload handling in Notify Payload
7869 implementation as protocol requires it. Added the new support
7870 into server and client lib as well.
7872 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7874 * Added support for multiple nicknames on same channel. [n] is
7875 added locally to the nickname if there are more than one same
7876 nicknames on the channel.
7878 * Server now sends all nicknames that matched WHOIS request.
7879 Client also shows the list received from server.
7881 * Added TOPIC command to client side. User can now set and show
7882 current topic on channel.
7884 * Added MOTD command to client and server. Also, server sends the
7885 motd when client connects to the server.
7887 * Changed version strings to comply ISO 8601.
7889 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7891 * Fixed protocol error handling in client library. It should now
7892 cope even if the SKE fails for some reason.
7894 * Made new protocol specification drafts for submitting to IETF.
7896 * Implemented TOPIC command to server in silcd/command.c.
7898 * Added two new notify types into lib/silccore/silcnotify.h:
7899 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7900 notify nickname change and topic setting/change on a channel.
7902 * API change of command_reply operation in client library. The
7903 application gets now the status type received from server as well.
7905 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7907 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7909 * Cras fixed and optimized the packet handling even further and
7910 it should work now. Minor change to the prototype of function
7911 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7913 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7915 * Added new function into lib/silcutil/silcschedule.[ch]:
7916 silc_schedule_with_fd to select() a specified fd. The function
7917 returns after timeout expires or data arrives or goes. The
7918 function is used by packet routines to wait that all data is
7919 received from network.
7921 * Fixed data reading from network in lib/silccore/silcpacket.c.
7922 The code now assures that all data is read from the fd and then
7923 continues packet processing. This was a bug fix since the code
7924 used to drop some data in some circumstances.
7926 * Added new function into lib/silcclient/client.[ch]:
7927 silc_client_start_key_exchange to start key exchange after
7928 connection has been established to server. The code internally
7929 now uses this funtion but its main purpose was to provide it
7930 for applications that perform their own connecting. After
7931 application has created a connection it merely calls this
7932 function to start the key exchange between client and server.
7933 The library takes care of everything else after that.
7935 Updated also lib/silcclient/README to explain the usage of
7938 * Do not send to application information that connection has
7939 been established. Application gets notified it by connect
7942 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Applied cras's patch to add silc_schedule_one function. The
7945 function runs scheduler once and returns.
7947 * Fixed the scheduler after cras messed it up. The timeout
7948 handling works now as it's supposed to work.
7950 * Added into lib/silccore/ silcnotify.h to include notify
7951 message types support. Changed silc_server_send_notify*
7952 functions, in server.[ch], to support those new notify types.
7953 Added the support for the notify types into client library,
7954 as well. Added new notify client operation into ops.h in
7957 * Changed silc_server_packet_send_to_channel to send normal
7958 packets instead of just channel message packets. The function
7959 is now used to send the notify packets to channels. It is not
7960 used to send channel message packets anymore, as server never
7963 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7964 va_arg()s as it seems to require it nowadays. I guess, if SILC
7965 is compiled with older va_arg() the new code should work anyway.
7967 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7969 * Splitted core library. Core library (lib/silccore) includes
7970 now only SILC protocol specific core (and common) components.
7971 Created new utility library (lib/silcutil) that includes more
7972 generic purpose stuff. The stuff for util library was taken
7973 from the old core library. This was minor and easy split.
7975 * Created SILC Client Library (lib/silcclient) that includes
7976 implementation of the SILC client without user interface. This
7977 was major move from silc/ directory. The code has been changed
7978 so that it is transparent towards the user interface. The
7979 silc/ directory includes now the same user interface as before
7980 and it uses the new client library. Read lib/silcclient/README.
7981 Basicly, the client library performs everything else related
7982 to SILC except user interface handling. Also, configuration
7983 files are considered to be part of user interface and library
7984 does not handle them.
7986 This change also changed a lot of structures, function naming etc.
7987 Most important change was that SilcClientWindow object was
7988 renamed to SilcClientConnection in the client library. Created
7989 also new file lib/silcclient/ops.h. Also added new files
7990 silc/local_command.[ch] and silc/client_ops.[ch].
7992 All these changes were made to make it easier for user interface
7993 designers to create what ever user interface for the SILC client
7996 It is also expected that the server will be moved to lib
7997 directory as well and SILC Server Library will be created;
7998 sometimes in the future.
8000 * Removed Local commands from lib/silccore/silccommand.h as
8001 they are application specific and new client library does not
8002 handle any of those anymore.
8004 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8005 old client implementation in silc/.
8007 * Added support for callback functions in SILC_LOG_* macros.
8008 Application can now set its own callbacks that will be called
8009 instead of using the default functions that will always print
8010 the debug messages to stderr (or stdout). Also, debugging can
8011 now be disabled by setting silc_debug to FALSE and re-enabled by
8012 setting it to TRUE. Note, that logging will still work even
8013 if debugging is disabled.
8015 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8016 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8017 silc_log_reset_debug_callbacks.
8019 * To enable debugging in silc client one must give now -d
8020 option on command line.
8022 * Changed silc_schedule_init to automatically allocate task queues
8023 if they are not allocated before calling it.
8025 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8027 * Added GMP 3.1 into math library.
8029 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8031 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8032 a channel in SILC network. The packet is used by servers and
8033 routers to notify other routers that user has left a channel.
8034 This little feature was missing until now. Added the feature
8035 to protocol specification as well.
8037 Added functions: silc_server_send_remove_channel_user and
8038 silc_server_remove_channel_user into server.[ch].
8040 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8041 lib/silccore/silcpacket.h. However, they are not implemented
8044 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8046 * Fixed joining to a channel and sending channel messages
8047 between server and router. The channel message sending should
8048 now work inside a cell.
8050 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8052 * Fixed the private message sending between server and router.
8053 The private message sending should now work inside a cell.
8055 * Added silc_server_replace_id into server.[ch] to replace
8056 existing ID in the SILC network.
8058 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8059 and silc_idlist_replace_server_id into idlist.[ch] in server.
8061 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8063 * Fixed the server to server connections. Server can again now
8064 connect to router. Router to router connections probably does
8067 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Added dynamic protocol registering support. Now protocols can
8070 registered and unregistered on the fly. Patch by cras.
8072 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8074 * Added lib/contrib directory to hold routines that some platforms
8075 don't have but are needed by SILC.
8077 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8078 into lin/contrib to provide getopt() and getopt_long() for
8079 those who don't have it.
8081 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8083 * Added AWAY command to client. When away message is set and
8084 client receives a private message packet the client automatically
8085 replies to the sender with the away message.
8087 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8088 bug seemed to be the cause of recent problems when compiling
8091 * Added version detection support to SKE protocol specification
8092 and added the new changes to the SKE implementation as well.
8093 There were other minor changes in the SKE protocol as well.
8095 Many changes in lib/silcske/silcske.[ch] and in
8096 lib/silcske/payload.[ch].
8098 * Added ^U functionality, clear input line. Patch from cras.
8100 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8102 * Mainly small bugfixes on core library. Fixed some debugging
8103 logging and buffer overflow in silclog.c.
8105 * Updated config.sub and config.guess on the distribution tree.
8107 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Added command lagging support in server. Client may execute
8110 commands now only once in two seconds.
8112 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8114 * Optimized packet reception. MAC computation and checking is now
8115 also more optimized. A lot previously duplicated code is now
8116 used as generic by both client and server.
8118 * Fixed key pair generation in clientutil.c
8120 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8122 * Added into lib/silccore/silcbufutil.[ch] new function;
8123 silc_buffer_realloc.
8125 * Moved generic packet sending/encryption functions to
8126 lib/silccore/silcpacket.[ch] from client and server. Some
8127 rewriting of the functions.
8129 * Moved all generic packet reception/decryption functions to
8130 lib/silccore/silcpacket.[ch] from client and server. The
8131 packet processing is now much cleaner in both client and server.
8132 These were major changes in both client and server.
8134 * Created many common functions in server to do packet sending.
8135 Previously code were duplicated a lot, this has been removed
8138 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Rewrote major parts of the ID cache system. Don't know
8141 whether it is better now or not but at least the API is more
8144 * Major rewrite on ID cache stuff on client because of the ID
8145 cache API changes. Added idlist.c to client.
8147 * Also major rewrite on ID cache stuff on server as well.
8148 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8149 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8150 in hand, instead they are all put into the ID cache system now.
8151 All server_idlist_* routines uses ID cache now instead of
8152 traversing its own lists (those lists does not exist anymore).
8153 SilcIDList though still exists. Also, SilcXXXEntry's are
8156 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Finally made the SKE implementation compliant to the protocol
8159 specification. All mp integers are now binary encoded as
8160 opposed being HEX encoded.
8162 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8165 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8166 functions: silc_[encode/decode]_pem. Also added function
8167 silc_encode_pem_file to PEM encode with newlines ('\n') for
8170 * SILC public keys are now encoded either PEM or binary. Same
8171 option is for private keys as well. By default private keys
8172 are binary encoded and public keys PEM encoded. Silly HEX
8173 encoding were removed.
8175 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8176 function to create fingerprints.
8178 * Fixed a bug in SHA1; does not change the original data anymore.
8180 * Partly implemented INFO command on client and server side.
8181 Fixed CLEAR command. Changes to SERVER command; show current
8182 server(s) when giving command without arguments. Added
8183 VERSION command to client.
8185 * Added check to server that unregistered connections cannot
8186 execute commands (unless it is specificly allowed).
8188 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8190 * Fixed screen refresh.
8192 * Fixed channel joining bug from client. On some circumstances
8193 client tried to join to a channel it had already joined.
8195 * Added public key verification process into client's protocol.c.
8196 The client now verifies the public key from user and saves
8197 it into ~./silc/serverkeys/ directory.
8199 Added into: clientutil.[ch]: silc_client_verify_server_key.
8201 * Changed SKE protocol's silc_ske_initiator_finish function
8202 to accept callback function that verifies the received public
8203 key. Removed old silc_ske_verify_public_key function.
8205 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8207 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8208 silc_pkcs_private_key[_data]_set.
8210 * Made the password and public authentication more cleaner in
8211 server's protocol.c.
8213 * Removed historic and obsolete protocol `channel_auth' from
8214 both client and server.
8216 * Removed wrong way of sending command status messages from
8217 server to client in server's command.c. The old way violated
8218 protocol specification.
8220 Changes to silccore/silccommand.[ch]: removed
8221 silc_command_encode_status_payload -> not needed anymore,
8222 changed silc_command_encode_payload_va to accept extra
8223 argument on variable argument list. The argument type must
8224 now be provided to the function. Also, added new function:
8225 silc_command_encode_reply_payload_va which is same as
8226 normal command_encode_payload_va except command status type
8227 is provided as extra argument.
8229 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8231 * Added ~./silc directory handling. The directory includes the
8232 public and private keys for the client.
8234 Added silc_client_check_silc_dir, silc_client_create_identifier
8235 and silc_client_load_keys.
8237 * Implemented SILC protocol compliant public key. Added public
8238 and private key saving to and loading from files.
8240 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8241 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8242 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8243 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8244 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8246 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8247 silc_pkcs_load_[public/private]_key.
8249 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8251 * Added silc_server_get_route (route.[ch]) to get connection
8252 data for the fastest route for given ID.
8254 * Implemented INVITE command on client and server. The command
8255 were re-defined in the SILC Protocol Specification and the
8256 implementation now complies with the specification.
8258 * Implemented PING command on client and server.
8260 * Implemented NAMES command on client and server. The server side
8261 supports currently only normal server not router server yet.
8262 Some changes to NAMES definition in SILC protocol specification.
8264 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8266 * Implemented LEAVE command on client and server.
8268 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8269 again. This change was made to the protocol as well. Server
8270 should not violate the protocol specification anymore.
8272 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8274 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8275 was tested. SOCKS4 was not but should work anyway.
