160 It is not able to send requested attributes in WHOIS command,
161 and also receive and process requested attributes. Added
162 silc_client_attribute_[add|del] and silc_client_attributes_get
163 functions. Added also `ignore_requested_attributes' to the
164 SilcClientParams to not use attributes in client. Affected
165 files are lib/silcclient/command.c, client_attrs.[ch],

186 * Changed the silc_attribute_payload_encode to support list
187 of attributes (function may be called several times to add
188 a new attribute). Removed the silc_attribute_payload_encode_list
189 function. The encoding function now also automatically encodes
190 the data, so the caller does not need to do that. Affected
191 files lib/silccore/silcattrs.[ch].
193 * Added support for replying on behalf of the user to the
194 Requested Attributes in WHOIS command in the server. Affected

262 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
264 * Added 'app_context' to silc_schedule_init. It is an
265 application specific context that is delivered to application
266 in task callback functions. Affected files are
267 lib/silcutil/silcutil.[ch].
269 * The hb_context in SilcSocketConnection is not freed
270 automatically anymore (application must free it). Freeing
271 it automatic is inconsistent. Affected files are
272 lib/silcutil/silcsockconn.[ch].
274 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

312 * Incoming file transfer request cannot use same session as
313 the sending session. This can happen when sending file to
314 yourself. Crashed the client on quit. Affected file
315 lib/silcclient/client_ftp.c. Bug #24.
317 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
319 * Implemented the draft-riikonen-precense-attrs draft and
320 the Attribute Payload into the lib/silccore/silcattrs.[ch].
322 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
324 * Distribute the SERVER_SIGNOFF notify also to local backup
325 routers from the primary router. The backup router may not
326 have the signing of local server directly connected and need
327 to know about the signoff. Affected file silcd/server_util.c.
329 * Use the primary router as the origin of the locally connected
330 server when it is disconnecting from the backup router since
331 that's where it really is coming from. Now the clients from
332 the disconnecting server are removed correctly and "shadow"
333 clients are not left to the backup router. Affected file
336 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
338 * If normal server is standalone and found existing but disabled
339 channel, do not re-create the channel since it creates
340 duplicate same channels. Affected file silcd/server.c.
342 * Added anonymous client connections support to server. New
343 "anonymous" configuration option to ConnectionParams section
344 added. If set to true, the username and hostname information
345 of the client will be scrambled and anonymous user mode is
346 set automatically to the user. Affected files are
347 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
349 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
351 * In JOIN notify handling, mark that the cache entry of the
352 client cannot be expired. Can cause crashes on normal
353 server (asserts client->channels). Affected file is
354 silcd/packet_receive.c.
356 * From now on distribution versions are used as protocol versions
357 instead of by default using the Toolkit base version as protocol
358 version. Affected file prepare.
360 * Do not set the locally resolved hostname for local client
361 entry but take what server sends. This way the real hostname
362 is showed in WHOIS for yourself. Affected file is
363 lib/silcclient/idlist.c and lib/silcclient/client.c.
365 * Resolve local info with IDENTIFY when connecting to server.y
367 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
369 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
370 for implied search (not needed on platforms which has native
371 pthreads library). Use --without-pthreads to disable threads.
372 Affected file is configure.in.pre
374 * Fixed --with-iconv on platforms which need to bypass (broken)
375 native iconv(). Affected file is configure.in.pre
377 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
379 * Moved -C option parsing in Irssi SILC client at same time
380 as other options. The UI was initialized earlier and caused
381 problems on command line. Bug #16. Affected file is
382 irssi/src/silc/core/silc-core.c.
384 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
386 * Added global variable silc_log_timestamp that tells silclog
387 wether to print or not the timestamp in the logging files.
388 Affected file lib/silcutil/silclog.[ch].
390 * Added silcd configuration option Timestamp in the Logging
391 section. Affected file silcd/serverconfig.[ch],
392 doc/example_silcd.conf.in.
394 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
396 * Fixed fingerprint checking to check for entirely empty
397 fingerprint instead of two first bytes when determining
398 if it is set. Bug #18. Affected file silcd/command.c.
400 * Fixed duplicate PKCS name registering to not allow it.
401 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
403 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

412 didn't generate any output. Affected file
413 lib/silccrypt/silcrng.c
415 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
417 * Rewrote iconv checking, introduce --with-iconv for systems
418 which rely on libiconv. Check if iconv() provided by libc
419 is good enough, otherwise demand libiconv. Affected file
422 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
424 * Search for ldopen() also in libc. This enables SIM support
425 on *BSD systems. Based on patch from Alex Zepeda. Affected
426 file configure.in.pre
428 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

458 * Fixed buffer overflow and security problems (loosing bits
459 in CFB encryption) in SILC RNG. Problems reported by
460 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
462 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
464 * Added yet more checks that client is not expired on global
465 list if it is on channels. Affected file is
466 silcd/command_reply.c.
468 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
470 * Merged c0ffee's MIME signal patch which adds support for
471 sending also MIME messages in Irssi SILC Client, and handling
472 received MIME messages in a signal (and perhaps doing something
473 to non-textual MIME messages).
475 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Fixed pending command deletion in server and client library
478 to check the whole list instead of breaking after first found.

486 whether a secret channel exists or not. Affected file
489 * If CMODE change fails during the mode setting, assure that
490 the old mode mask is set for the channel back. Affected
491 file silcd/command.c.
493 * Fixed passphrase saving on +a channel on normal server
494 after successful JOIN command. Affected file silcd/command.c.
496 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
498 * Remove server/router operator privileges in DETACH command,
499 since it's possible to resume to server where these
500 privileges would not be allowed for the client. Affected
501 file silcd/command.c.
503 * Do not set to wait for backup in rehash of the server.
504 Affected file silcd/server.c.
506 * Do not check listener sockets when counting how many
507 socket connections we have. Affected file is
510 * Do not announce disconnected clients that are remaining
511 in history (for WHOWAS). This is because SIGNOFF notify
512 for these has been sent earlier already. Affected file
515 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Buffer overflow with CUMODE command's mode->mode character
518 conversion. Reported by Ville Räsänen. Affected file

521 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
523 * Allow heartbeat packets to go disabled connections anyway.
524 Affected files silcd/server.c and silcd/packet_send.c.
526 * Do not broadcast New Channel packets with List flag set
527 in the packet to backup routers. The router must check
528 for the correctness of the packets before sending them.
529 It is possible that router will have enforce Channel ID
530 change and this would cause desync in the backup router.
531 Affected file silcd/packet_receive.c.
533 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
534 are handled in list parsing. They are not list packets
535 anymore. Affected file silcd/packet_receive.c.

547 * Notify distribution to backup routers was missing from
548 the silc_server_send_notify_dest function which caused
549 desyncing problems with backup router. Affected file is
552 * The client's channel removing was working wrong on
553 backup router. It assumed that it doesn't know global
554 information but backup router does know. For this reason
555 it could remove channel when it wasn't supposed to do that.
556 Affected file silcd/server.c and silcd/server_util.c.
558 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
560 * Stop for a couple seconds after badkup router has become
561 primary router. Affected file silcd/server.c.
563 * Added silc_server_remove_servers_by_server, which is used
564 to remove servers originated from some other server. Also
565 clients of those servers can be removed too. Affected file
566 silcd/server_util.[ch].
568 * When removing clients after a server has signed of remove
569 also all servers behind that server (unless they are known
570 to be available locally), and send SERVER_SIGNOFF for each
571 of the server separately. Also the signed off clients are
572 sent now separately per signed off server. The affected files
573 are silcd/server.c and silcd/server_util.[ch].
575 * All servers added with silc_idlist_add_server must always
576 have both "router" and "connection" pointers set. Otherwise,
577 bad server entries may be left around in the cache.
578 Affected file silcd/command_reply.c.
580 * Do not create the channel key in NEW_CHANNEL packet
581 processing if the channel is empty. Affected file
582 silcd/packet_receive.c.
584 * Completed backup router support for standalone routers.
585 Supports also servers in the cell that do not use the backup
588 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
590 * Fixed a bug in silc_string_regexify which did not add '^'
591 at the start of each string, and thus the matching was
592 not explicit. For example ban list iikone@*!*@* would
593 match also "priikone", which is wrong, it would have to be
594 *iikone@*!*@* to match also "priikone". Affected
595 file lib/silcutil/unix/silcunixutil.c.
597 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
599 * Enable all local server connections before updating client
600 caches when we've become backup router. Otherwise, signoff
601 packets may not reach the clients. Affected files are
602 silcd/server.c and silcd/server_util.[ch].
604 * Fixed a bug in version string parsing which could crash
605 the program with specially formatted version string.
606 Bug reported and patch provided by Ville Räsänen. Affected
607 file lib/silcutil/silcutil.c.
609 * Handle the disconnection immediately when DISCONNECT
610 packet is received in server. Affected file silcd/server.c.
612 * Primary router now waits a short time (10 seconds) for
613 backup router connection before accepting any other
614 connection (except local). Affected file silcd/server.c,
617 * Fixed a crash in client libary in NICK_CHANGE notify when
618 NICK_CHANGE arrived for client entry we are resolving
619 currently. Affected file lib/silcclient/client_notify.c.
621 * Call the sconn->callback completion even if error had
622 occurred. Start reconnecting always if connection to
623 primary router fails during backup router protocol.
624 Affected files silcd/server.c and server_backup.c.
626 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
628 * Added functions silc_server_send_opers and
629 silc_server_send_opers_notify to send packets stricly
630 to operators. Added macro SILC_SERVER_SEND_OPERS macro
631 to send variable argument notify to operators.
632 Affected files silcd/packet_send.[ch] and silcd/server.h.
634 * Removed UMODE rights checking with UMODE_CHANGE notify.
635 Affected file silcd/packet_receive.c.
637 * Server/router operator now receives notify when network
638 switches to backup router and when it resumes the use of
639 primary router. Affected file silcd/server.c and
640 silcd/server_backup.c.
642 * Fixed the updating of client information after backup
643 resuming protocol is over; update all except local clients
644 to the new primary router. The affected file is
647 * Added support for closing active connections in rehash
648 that were unconfigured by the user. Supports currently
649 closing server and router connections. Affected file
652 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
654 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
657 is NULL since seems that on some platforms NULL is allowed
658 and on some it's not. Fallback encoding is used instead.
659 Affected file lib/silcutil/silcstrutil.c.
661 * Fixed statistics updating for incoming server connection
662 which could cause problems when re-connecting. Affected
665 * Preliminary backup router support for standalone router
666 added. Affected files in silcd/.
668 * Mark server connections in backup router disabled before
669 and after backup protocol. Affected file is
670 silcd/server_backup.c.
672 * Added support for reconnecting to remote server connection
673 even if the protocol fails, and if the configuration wants
674 us to keep trying to connect anyway.
676 Server connection is not allowed to backup router if
677 backup router does not have connection to primary router yet.
679 Affected file is silcd/server.c.
681 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Added silc_client_udpate_server function to update changed
684 server info. Affected file lib/silcclient/idlist.[ch].
686 * Added check for server entries that are being resolved when
687 notify is received. If being resolved, handle the received
688 notify only after it's resolved so that all notifys are
689 handled in same order as received from the server.
691 Added similar resolver check to channel entries. Every
692 notify that cause resolving of any information that affects
693 channel entry marks the channel entry in waiting state.
694 After whatever resolving is over the waiters are signalled
695 and only then the notifys are handled in the same order
696 as delivered from the server.
698 Affected files are lib/silcclient/idlist.[ch], and
701 * Fixed KILLED notify handling in normal server. Affected
702 file silcd/packet_receive.c.
704 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
705 is locally connected, or was locally connected (but may
706 be detached and connection is not active). Added also
707 SILC_IS_LOCAL for checking this status. Affected files
708 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
709 silcd/server.c and silcd/server_internal.h.
711 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
713 * Don't send or handle TOPIC_SET if topic is already set and
714 is same as being set. Affected files silcd/command.c and
715 silcd/packet_receive.c.
717 * Fixed CMODE change rights checking to work correctly when
718 removing modes by operator. Affected file is
721 * Fixed some handling with New Channel packet in router and
722 fixed some CMODE_CHANGE notify handling in server and router.
723 Affected file is silcd/packet_receive.c.
725 * Changed "disconnect" client operation to include the
726 reason of the disconnection and optional disconnection
727 message. Affected file lib/silcclient/silcclient.h.
729 * Made the compilation of lib/contrib/ stuff conditional.
730 Affected files configure.in.pre, lib/contrib/Makefile.am.
732 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
734 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
735 to the sender of the notify too, to avoid situation where two
736 notifys are in the network at the same time going to oppsite
737 directions. Affected file silcd/packet_receice.c.
739 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
741 * Delete the client from channel even if the cilent->id is
742 NULL. It was possible that client was deleted without
743 removing from channels (theoretically at least). Affected
744 file silcd/server.c and silcd/server_util.c.
746 * Free the client data too when resuming is not successful.
747 Affected file silcd/packet_receive.c.
749 * Merged some code from c0ffee's silc-plugin. Affected files
750 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
752 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
753 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
754 to the primary router connection, the other one returns
755 TRUE if packet must be broadcasted to network.
757 * All notifys that are destined to primary router (to network)
758 are now automatically sent to backup routers even if the
759 router is standalone (and has backup router). Affected files
762 * Added --without-irssi and --without-silcd configuration
763 options for disabling the compilation of these applications.
764 Affected file configure.in.pre and prepare.
766 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
768 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
769 UTF-8 encoding and decoding. Added also new encodings
770 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
772 Added also SILC_STRING_LANGUAGE which is language and charset
773 specific encoder and decoer for those platforms that support
774 iconv(). It can convert the UTF-8 to and from the locale
775 specific character set.
777 Affected file lib/silcutil/silcstrutil.[ch].
779 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
781 * Added function silc_get_command_name to the file
782 lib/silcutil/silcutil.[ch].

789 * Save the channel passphrase when received succesful JOIN
790 command reply from router, on normal server. Otherwise
791 joinig +a channels from normal server is not possible.
792 Affected file silcd/command.c.
794 * Fixed a bug in TOPIC_SET notify handling. The notifier
795 may be other than client too, like server or channel.
796 It expected it to always be only client and ignored the
797 notify. Affected file silcd/packet_recieve.c.
799 * Removed some (unnecessary) debug printing from
800 lib/silccore/silcid.c and lib/silccore/silcargument.c.
802 * Do not force CMODE_CHANGE when server is announcing new
805 Router announces stuff only after server reannounces channel
806 after CHANNEL_CHANGE notify.
808 These fixes optimizes the announcing procedure, and perhaps
809 fixes some problems too. Affected file silcd/packet_receive.c.
811 * Fixed SERVER_SIGNOFF sending to local clients. It was
812 totally broken and sent the notify to all local clients,
813 instead of only to those that was on same channel as the
814 signing off clients. Affected file silcd/server_util.c.
816 * Added -D option to server. It can be used to give debug
817 level. The levels are from 0 - 99, and are predefined for
818 smooth server debugging. (see silcd.c for the predefined
819 levels). Affected file silcd/server.c.
821 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
823 * Fixed a bug in Irssi SILC client to close the connection
824 properly when disconnecting from server. Affected file
825 irssi/src/silc/core/client_ops.c.
827 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
829 * When authenticating as founder during JOIN command, check
830 that the one authenticating becomes the only founder on the
831 channel. Affected file silcd/command.c.
833 * Better checking for founder mode setting when CUMODE_CHANGE
834 notify is received. Affected file silcd/packet_receive.c.
836 * Close all connections when shutting down the server by sending
837 DISCONNECT packet. Close all listeners too when shutting
838 down the server. Affected file silcd/server.c.
840 * Handle DISCONNECT packet correctly in client library by
841 calling the "disconnect" client operation. Affected file
842 lib/silcclient/client.c.
844 * Handle local errors correctly during resuming. Affected
845 file lib/silcclient/client.c.

871 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
872 core library, and implemented it. All textual messages SHOULD
873 use this flag and the message MUST be UTF-8 encoded.
874 All text messages sent by Irssi SILC client are now UTF-8
875 encoded (regardless whether the terminal supports UTF-8 or not).
876 Affected files are lib/silccore/silcchannel.h,
877 irssi/src/silc/core/silc-servers.c, silc-channels.c and

912 that there isn't anyone else with founder mode on the channel.
913 The one that authenticated will become founder and anyone
914 else is demoted. Affected file silcd/command.c.
916 * Added error printing of any error that has occurred during
917 any command in client library. Affected file is
918 irssi/src/silc/core/client_ops.c.

966 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
968 * Made the private key generation after expiration optional.
969 If not created after expiration the old key will re-expire
970 at a later time (and thus key pair is not necessary to
971 change). Affected file irssi/src/silc/core/clientutil.c.
973 Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1579 Added new options m and M to CMODE command in Irssi SILC
1580 client to set these modes.
1582 * Deprecated all administrative commands from SILC protocol
1583 since they are highly implementation specific commands.
1584 Updated protocol specs. Moved the old commands in
1585 implementations to private range of command types. Affected
1586 files are silcd/command.c, lib/silcclient/command.c and
1587 lib/silcclient/command_reply.c. Protocol TODO #8.
1589 * Fixed a bug in server where sending unknown command crashes
1590 the server. Affected file silcd/command.c.
1592 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1594 * Added SILC_PROTOCOLVERSION macro to check protocol version
1595 of a socket connection. The affected file is
1596 lib/silcutil/silcsockconn.h.
1598 * Added better error logging in rekey protocol. Affected file
1601 * Do not check public key types in SKE during rekey. Affected
1602 file lib/silcske/payload.c.
1604 * Fixed the rekey protocol with PFS, which was totally broken.
1605 Affected file silcd/protocol.c.
1607 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1609 * Some client implementations quit network by doing first LEAVE
1610 and then immediately SIGNOFF (like Bombyx). We now do check
1611 after a short time after LEAVE notify and check whether the
1612 client is still valid after LEAVE, and if not we remove it from
1613 cache. Affected file is lib/silcclient/client_notify.c.
1615 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1617 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1618 it's good not to have security holes here.
1620 * Fixed a negative refcount situtuation for the config context.
1621 Affected file is silcd/serverconfig.c.
1623 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1625 * ROBOdoc documented lib/silcutil/silcutil.h.
1627 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1629 * Optimized even more the SilcPacketContext structure. Now
1630 totally saved 16 bytes of memory per context after optimization.
1631 Affected files are lib/silccore/silcpacket.[ch].
1633 * Made strict checks for valid SILC IDs. Affected file is
1634 lib/silccore/silcid.c.
1636 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1638 * Changed the object argument for silc_cipher_register,
1639 silc_hash_register, silc_hmac_register and silc_pkcs_register
1640 to const. Affected files are lib/silccrypt/silccipher.[ch],
1641 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1643 * Changed the silc_get_username and silc_get_real_name to
1644 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1646 * Fixed the Irssi SILC Client to use the silc_get_username and
1647 silc_get_real_name insted of glib routines since the glib
1648 routines only corrupt stack. Fixes the Irssi SILC to work in
1649 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1651 * Fixed the Irssi to not use g_get_home_dir since it crashes
1652 or returns garbage on cygwin and corrupts stack. Added function
1653 get_home_dir to Irssi routines. Affected files are
1654 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1656 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1658 * Made some structure optimizations. SFTP memory FS MemFSEntry
1659 entry structure. Optimized SilcTask structure. Optimized
1660 SilcPacketContext structure.
1662 Affected files lib/silcsftp/sftp_fs_memory.c,
1663 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1665 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1667 * And yet again reverted back the config thing since Johnny
1668 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1671 * Fixed memory leaks from config object. Affected files are
1672 silcd/serverconfig.[ch].
1674 * Added support for adding new connections to the server in rehash.
1675 After rehash they take effect.
1677 Added support for changing the maximum allowed connections in
1678 rehash. The number can grow but going smaller is not supported.
1680 Added function silc_server_num_sockets_by_remote to the
1681 silcd/server_util.[ch].
1683 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1685 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1687 * Added preliminary checking during config parsing for a valid
1688 public/private key and removed further checks in the code.
1689 Affected files are silcd/serverconfig.[ch], server.c.
1691 * Moved functions silc_server_drop() and silc_server_daemonise()
1692 from server.c to silcd.c since they are stricly related to
1693 the application activity.
1695 * Reverted a small part of the automatic ref/unref since
1696 it caused a double unref in some situations. Affected
1697 files are silcd/silcd.[ch], server.c, serverconfig.c.
1699 * Added some .cvsignore files in the lib directory.
1701 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1703 * Fixed silc_net_gethostbyaddr to correctly resolve by
1704 address. Affected file lib/silcutil/silcnet.c.
1706 * Fixed the notify relaying to client. The HMAC to be used
1707 with relayed packets ws wrong and caused decryption failure
1708 at the client end. Affected file is silcd/packet_receive.c.
1710 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1712 * Created new branch silc_protocol_1_0_branch.
1714 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1716 * Changed the silc_server_config_* routines to be SilcServer
1717 independent. They are now officially application specific code
1718 and not part of generic server implementation. Affected files
1719 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1721 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1723 * Added automatic referencing of config context in the
1724 silc_server_config_alloc, and automatic unreferencing in the
1725 silc_server_config_destroy. Affected files are
1726 silcd/serverconfig.[ch], silcd/silcd.c.
1728 * Fixed the silc_log_quick handling in the logging routines.
1729 It didn't log quickly when it was TRUE. Affected file is
1730 lib/silcutil/silclog.c. Also the flush delay was set even
1731 if it was 0 in config file. Affected file is
1732 silcd/serverconfig.c.
1734 * Added support for changing key pair of the server in rehash.
1735 Affected file silcd/server.c.
1737 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1740 too early, before getting the channel entry. Affected file
1741 is silcd/packet_receive.c.
1743 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1745 * Added functions silc_server_config_[ref/unref], these are used
1746 to prevent that the config object is destroyed.
1748 No longer directly affect global variables silc_log_quick and
1749 silc_log_delay, they are first cached inside the config object
1750 and then applied with silc_server_config_setlogfiles().
1752 silc_server_config_set_defaults() is now internal to
1753 serverconfig.c, there are no reasons to show this internal stuff
1756 Affected files are silcd/serverconfig.[ch].
1758 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1759 fprintf's to stderr, since some code may be executed again after
1760 the server went into the background. Affected files are
1763 * Added rehash support. Added function silc_server_rehash() that
1764 will perform all the basic tasks of the rehashing procedure.
1766 * Added command line option `-x, --hexdump'. This will enable the
1767 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1768 The option `--hexdump' implies `--debug'.
1770 * Fixed a bad bug in the logging APIs (silcutil library) where
1771 the application would crash after calling silc_log_reset_all().
1773 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1775 * Fixed the KICKED notify handling in client library to
1776 correctly remove the channel and all entries from the
1777 channel when I was kicked. This bug crashed the client.
1779 Fixed yet another but in KICKED notify handling to remove
1780 the kicked client correctly from the channel.
1782 Affected file is lib/silcclient/client_notify.c.
1784 * Fixed a minor bug in looking up correct client entry
1785 in KICKED notify in server. Affected file is
1786 silcd/packet_receive.c.
1788 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1789 sources correctly to distribution. Fixes --with-gmp option.
1791 * Removed the manual rehashing from ID Cache, and changed it
1792 to use the SILC Hash Table's auto rehash feature. Affected
1793 file is lib/silccore/silcidcache.c.
1795 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1797 * Fixed a bug in the silc_client_nickname_format function that
1798 handles the multiple same nickname formatting. Two clients
1799 with same nickname caused problems after the first one left
1800 and rejoined. It didn't format the nickname correctly.
1801 Affected file is lib/silcclient/idlist.c.
1803 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1805 * Don't change the topic if olod topic is same as new one.
1806 Affected file is silcd/packet_receive.c.
1808 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1810 * Added cross-reference support to the SILC Documentation
1811 generator. All types across all HTML files are now cross-
1812 referenced. Affected files util/robodoc/generator.c and
1813 scripts/silcdoc/silcdoc.
1815 * Added file lib/silcutil/silctypes.h to include all the
1816 arithmetic type definitions and some macros. Removed
1817 includes/bitmove.h and moved macros to silctypes.h.
1819 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1823 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1825 * Added `type' argument to silc_id_payload_parse_id function which
1826 now returns the type of the ID to the sent pointer. Affected
1827 file is lib/silccore/silcid.[ch].
1829 * Added check for CMODE_CHANGE notify type that mode change is
1830 allowed by the sender. Affected file silcd/packet_receive.c.
1832 * Added check for CUMODE_CHANGE notify type that mode change is
1833 allowed by the sender. Affected file silcd/packet_receive.c.
1834 Added the ID type as CUMODE_CHANGE notify type as argument
1835 to the `notify' client operation. Affected files are
1836 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1838 * Added function silc_client_add_server to the client library.
1839 Added support for resolving also channel and server info when
1840 received unknown entity in notify packet. Affected files are
1841 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1843 * Added function silc_command_get_status to return the command
1844 status from the command reply's argument payload. Affected files
1845 are lib/silccore/silccommand.[ch].
1847 * Added check for KICKED notify type that the kicking is
1848 allowed by the client. Affected file silcd/packet_receive.c.
1850 * Created function silc_get_input which can be used to get input
1851 (echo on or off) from user on command line. Affected files are
1852 lib/silcutil/silcutil.[ch].
1854 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1856 * Optimized silc_server_packet_relay_to_channel function.
1857 Added new function silc_channel_message_payload_encrypt which
1858 can be called directly if channel message payload needs to
1859 be encrypted and is already encoded (no need to call _encode
1860 function). Packet relaying is now done by router without any
1861 extra memory allocations. Affected files are
1862 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1863 silcd/packet_send.c.
1865 * Fixed the INVITE notify handling. It took wrong arguments
1866 as invite list and invite delete. Affected file is
1867 silcd/packet_receive.c.
1869 * Added check for TOPIC_SET notify type that the topic change is
1870 allowed by the client. Affected file silcd/packet_receive.c.
1872 * Added check for INVITE notify type that inviting is allowed by
1873 the client. Affected file silcd/packet_receive.c.
1875 * Changed the silc_server_client_on_channel to return the
1876 SilcChannelClientEntry as well. Moved the function
1877 silc_server_check_cmode_rights to server_util.[ch].
1878 Affected files are silcd/server_util.[ch], silcd/command.c.
1880 * Added function silc_server_check_umode_rights to check whether
1881 changing client's user mode is allowed. Added check for
1882 UMODE_CHANGE notify type that the umode change is allowed
1883 by the client. Affected files are silcd/server_util.[ch],
1884 silcd/packet_receive.c and silcd/command.c.
1886 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1888 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1889 ID length. It ignored that ID can be IPv6 based as well.
1890 Affected file lib/silccore/silcpacket.h.
1892 * Fixed the silc_id_id2str and silc_id_str2id to take the
1893 IPv6 address offset's into consideration. Affecte file is
1894 lib/silccore/silcid.c.
1896 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1898 * Fixed the internal Unix scheduler functions to check for
1899 NULL context they may receive. The affected file is
1900 lib/silcutil/unix/silcunixschedule.c.
1902 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1904 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1905 can specify different directory with --home command line
1906 parameter. Affected files irssi/src/silc/core/client_ops.c,
1909 * SILC-specific commands aren't now executed if the active server
1910 isn't of SILC-type, so there won't be problems with having
1911 IRC and SILC protocol support in same client. Affected files
1912 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1915 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1917 * Improved the signal support in SILC Schedule. Added new
1918 function silc_schedule_signal_call which is used by application
1919 to mark a signal to be called. It is now safe to perform
1920 any kind of tasks in signal callbacks since it is guaranteed
1921 that the application specified signal callback is called
1922 after the signal is over. Affected files are
1923 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1925 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1927 * Added `name' field to SilcChannelPrivateKey to represent
1928 application given name for the key. Moved also the context from
1929 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1930 Added the `name' argument also to the function
1931 silc_client_add_channel_private_key.
1933 Added function silc_client_current_channel_private_key to set the
1934 current channel private key in use.
1936 Added "change" command to KEY command which can be used to change
1937 the current channel private key. Bound the command also to
1938 alt+K (Alt+Shift+k).
1940 Also affected files lib/silcclient/client_channel.c,
1941 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1943 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1945 * Added silc_rng_get_byte_fast function in to the
1946 lib/silccrypt/silcrng.[ch].
1948 * Changed the interface of silc_packet_assemble and the
1949 silc_packet_send_prepare. If silc_packet_assmble is now
1950 called the application does not call silc_packet_send_prepare
1951 because the library will call it automatically. These
1952 interfaces now also return a reference to the outgoing buffer
1953 which includes the assembled packet, which the application can
1954 use to encrypt the packet.
1956 Affected files are lib/silccore/silcpacket.[ch],
1957 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1958 silcd/packet_send.c, server_backup.c and packet_receive.c.
1960 * Fixed a packet sending bug on very high load, where outgoing
1961 packet queue wasn't handled correctly and packets got corrupted.
1962 Affected files are lib/silcutil/*/silc*sockconn.c,
1963 lib/silcclient/client.c and silcd/server.c.
1965 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1967 * Added macro SILC_PACKET_DATALEN which can be used during
1968 packet assembling to check whether the data to be added to
1969 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1970 len is truncated until it fits it.
1972 Added checks for maximum length of channel message payload and
1973 private message payload also.
1975 Added checks for maximum packet length in server and in
1978 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1979 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1980 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1981 lib/silcclient/client_prvmsg.c.
1983 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1985 * Added silc_server_packet_queue_purge call to the
1986 silc_server_disconnect_remote to assure that all data in the
1987 queue before disconnecting is sent to the network. Affected
1988 file silcd/server.c.
1990 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1992 * Added the deleting of server's own ID cache entry to the
1993 silc_server_free function. Free also everything else that
1994 has been allocated in silc_server_init. The affected file
1997 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1999 * Added functions silc_parse_version_string, silc_version_to_num,
2000 and silc_ske_parse_version to parse SILC protocol style version
2001 strings. Affected files lib/silcutil/silcutil.[ch] and
2002 lib/silcske/silcske.[ch].
2004 * Added new configuration params: version_protocol, version_software
2005 and version_software_vendor to specify what version the remote
2006 host must at least be to be able to connect to server. The vendor
2007 string can be regex matched too. Added new function
2008 silc_server_connection_allowed to check maximum number of allowed
2009 connections, and allowed versions for incoming connections.
2010 Affected files are silcd/server.c, server_util.[ch] and
2013 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2015 * Added preliminary support for signals in scheduler. The
2016 signals we care about are now blocked always when the scheduler
2017 is locked. This way we can synchronise the use of signal with
2018 scheduler. It is guaranteed that when signal occurs the scheduler
2019 is not locked, and thus new tasks can be safely added to the
2022 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2023 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2024 Added new platform specific routines
2025 silc_schedule_internal_signals_[un]block and
2026 silc_schedule_internal_signal_[un]register.
2028 Added new functions to SILC Schedule API:
2029 silc_schedule_signal_[un]register. Each signal that application
2030 is going to use should be registered to the scheduler.
2032 Affected files are lib/silcutil/silcschedule.[ch],
2033 lib/silcutil/*/silc*schedule.c.
2035 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2037 * Check for unauthenticated client and server in the
2038 silc_server_new_client and silc_server_new_server functions.
2039 Affected file silcd/packet_receive.c.
2041 * Added function silc_string_is_ascii to check whether given
2042 string is 7-bit ASCII string. Affected files are
2043 lib/silcutil/silcutil.[ch].
2045 * Added function silc_id_is_valid_server_id into the
2046 silcd/serverid.c and added checking for valid Server ID's in
2047 silc_server_new_server. The Server ID must always be based
2048 on the server's public IP address.
2050 * Added logging of DISCONNECT packet message in the server.
2051 Affected file silcd/server.c.
2053 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2055 * Changed all library interfaces that use Global RNG to also
2056 accept SilcRng as argument. Affected files are
2057 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2058 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2059 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2060 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2061 lib/silccrypt/rsa.c.
2063 * Added function silc_pkcs_generate_key to the
2064 lib/silccrypt/silcpkcs.[ch] for applications so that they
2065 don't need to do pkcs->pkcs->init calls anymore.
2067 * Remove SilcSocketConnection from the SFTP API since it really
2068 wasn't needed there. The application has the information
2069 saved in its contexts anyway and the SFTP layer doesn't need
2070 know about it. Affected files lib/silcsft/silcsftp.h and
2071 lib/silcsftp/sftp_[server/client].c.
2073 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2074 The SilcSimContext is not SilcSim.
2076 * Fixed possible buffer overflows in silc_id_render in the
2077 lib/silcutil/silcutil.c.
2079 * On EPOC the global crypto module lists are not used at all

2081 algorithm list on EPOC. Affected files are
2082 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2085 * Fixed the handling of third parameter of KICKED notify, since
2086 it was mistakenly updated to SILC Protocol 1.0 even though it
2087 is to be included in 1.1. Since it is not in 1.0 it is not
2088 mandatory, and this fix now handles it only if it is provided,
2089 and it is not error if it is not provided. Affected file
2090 lib/silcclient/client_notify.c.
2092 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2128 hash public keys and compare public keys in hash table. Affected
2129 file lib/silcutil/silcutil.[ch].
2131 * Added support for specifying multiple public keys for Client
2132 connection section in server configuration file. This makes it
2133 possible to accept multiple public keys from same host, or to
2134 make a section that accepts any incoming host, and have the
2135 accepted public keys listed in the section.
2137 Added functions silc_sever_[find/get]_public_key, added the
2138 support for this actually to all connection sections but only
2139 the Client section is currently allowed to specify multiple
2142 Affected files are silcd/server.c, server_internal.h,
2143 command.c, protocol.c, server_util.[ch], packet_receive.c.

2157 Affected files are lib/silcutil/silclog.[ch].
2159 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2161 * Fixed the server to check correctly the amount of connections
2162 from single host, by checking also the type of the connection.
2163 Fixed also the comparison of number of connections and number
2164 of allowed connections. Affected files are silcd/server.c,
2167 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2246 application does not need to define them. Affected file
2247 includes/silcincludes.h.
2249 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2250 old name went against naming convention. Applications now
2251 include "silcclient.h" instead of "clientlibincludes.h".
2252 Removed includes/clientlibincludes.h, it is redundant now.
2254 * Renamed includes/version.h to silcversion.h.
2256 * Added really preliminary support for OS/2 into the util
2257 library. Only thread & mutex API is implemented, others
2258 are still to be implemented. Created the lib/silcutil/os2/
2259 directory. Created also file includes/silcos2.h.

2292 * Added `user_count' to the SilcChannelEntry which now tells the
2293 number of users on the channel. The user count is now saved
2294 in normal server of global channels as well. Affected files
2295 silcd/server.c, idlist.h, packet_receive.c and command.c.
2297 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2298 include file utility functions.
2300 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2301 instead of calling directly OS routines.
2303 * Fixed NICK change printing in Irssi SILC Client. Fixed
2304 KICKED notify printing in Irssi SILC Client. Affected file
2305 irssi/src/silc/core/client_ops.c.

2311 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2313 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2314 the SKE interface a bit.
2316 * Fixed padding problem in PKCS#1. The padding was not actually
2317 random since the random number generator was used incorrectly.
2318 This security bug affects only when encrypting with PKCS#1, and
2319 it is not currently used at all in SILC. SILC only use signing
2320 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2322 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2375 Affected files are silcd/serverconfig.[ch].
2377 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2379 * Fixed command line parameter handling. All SILC initialization
2380 is now done in silc_core_init() which also fixes autoconnecting
2383 Affected files irssi/src/silc/core/silc-core.c,
2384 irssi/src/fe-text/silc.c.
2386 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2388 * Added new configuration options and blocks:
2389 keepalive_secs, reconnect_count, reconnect_interval,
2390 reconnect_interval_max, reconnect_keep_trying and
2391 require_reverser_lookup. Added ConnectionParam block, and
2392 implemented the connection parameters when connecting as
2393 initiator and when accepting connections as responder.

2396 whether given configuration value has been given already.
2398 Affected files silcd/serverconfig.[c], server.[c].
2400 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2401 algorithm parts and created new file silcalgs.conf, that
2402 is now included from the example_silcd.conf.in.
2404 * Optimized the silc_server_connect_to_router_second to take
2405 the connection configuration object from the SilcServerConnection
2406 object instead of finding it during the connecting phase.
2407 Added the configuration object to SilcServerConnection struct.
2408 Affected files silcd/server_internal.h, server.c.
2410 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2412 * Add the client on channel after it was resolved at the
2413 channel message receiving, and it was not already on the
2414 channel. Affected file lib/silcclient/client_channel.c.
2416 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2418 * Fixed the public key authentication to allocate always the

2432 authentication to be set at the same time.
2434 Added `prefer_passphrase_auth' setting in config file which
2435 can be used to set to prefer passwd auth if both passwd and
2436 public key is set. If not set, public key is preferred.
2437 This has effect only when being initiator (responder will try
2440 Added support for authentication with passphrase and public key
2441 at the same time. The passphrase is tried first always since
2442 it is faster to check.
2444 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2446 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2476 as header filenames.
2478 * Removed lib/silcclient/README and created HTML file
2479 lib/silcclient/silcclient_using.html, which is now included
2480 as part of Toolkit documentation.
2482 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2484 * Fixed CUMODE_CHANGE notify handling to change the mode of
2485 correct client. Affected file lib/silcclient/client_notify.c.
2487 * Make silc_rng_alloc fail if it cannot allocate the sha1
2488 hash algorithm. Affected file lib/silccrypt/silcrng.c.

2492 * Fixed the file transfer's key agreement payload to include
2493 zero port also if the hostname is NULL because it could not
2496 Call file transfer monitor callback now also if error occurs
2497 during key agreement protocol.
2499 Changed the silc_client_file_send interface to return the
2500 SilcClientFileError instead of session id. The session ID
2501 is returned into pointer provided as argument.

2513 is changed and +k mode is set in the channel. Affected file
2514 irssi/src/silc/core/silc-channels.c.
2516 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2517 SILC_LOG_WARNING to give out Warning and not Error. Affected
2518 file lib/silcutil/silclog.c.
2520 * Fixed the channel message payload decryption in the function
2521 silc_channel_message_payload_decrypt to not modify the original
2522 buffer before it is verified that the message decrypted
2523 correctly. Otherwise, next time it is called with correct
2524 channel key it won't encrypt since the payload is corrupted.
2525 Affected file lib/silccore/silcchannel.c.
2527 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2537 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2539 * Fixed a bug in hash table internal routine for traversing
2540 the table with foreach callback. The current entry may
2541 become invalid in the callback but it was referenced after
2542 the callback returned.
2544 Do not allow auto rehashing of hash table during the
2545 silc_hash_table_foreach operation, for same reasons as it is
2546 not allowed for SilcHashTableList. Affected files are
2547 lib/silcutil/silchashtable.[ch].
2549 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2551 * Defined DLLAPI into silcincludes.h and silcwin32.h for

2555 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2557 * Fixed private message handling. It used some old code that
2558 caused the client to crash. Affecte file is
2559 lib/silcclient/client_prvmsg.c.
2561 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2563 * Added function silc_client_add_channel,
2564 silc_client_replace_channel_id, and removed functions
2565 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2566 from client library.
2568 * Added cross reference of the joined channels to the
2569 SilcClientEntry, and changed the SilcChannelEntry's
2570 users list to SilcHashTable. The affected files are
2571 lib/silcclient/idlist.[ch].
2573 * Fixed a bug in hash table tarversing. While the hash table
2574 is traversed with SilcHashTableList the table must not be
2575 rehashed. It is now guaranteed that auto rehashable tables
2576 are not rehashed while tarversing the list. Also defined that
2577 silc_hash_table_rehash must not be called while tarversing
2578 the table. Added function silc_hash_table_list_reset that must
2579 be called after the tarversing is over. The affected files are
2580 lib/silcutil/silchashtable.[ch].
2582 * Changed all hash table traversing to call the new
2583 silc_hash_table_list_reset in server and in client library.
2585 * Added function silc_client_on_channel to return the
2586 SilcChannelUser entry if the specified client entry is joined
2587 on the specified channel. This is exported to application as
2588 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2590 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2592 * Fixed founder regaining problem with JOIN command on normal
2593 server. The notify for mode change must be sent always and
2594 not only if !cmd->pending. Affected file silcd/command.c.
2596 * Fixed the WHOWAS command's reply sending to support the
2597 lists correctly. Affected file silcd/command.c.
2599 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2601 * When sending JOIN command to router for processing the
2602 sender's old command identifier was not saved back to the
2603 sender's command context, fixed now. The affected file is
2606 * Create the key in JOIN command of the router did not return
2607 the channel key, added check for this. Affected file is
2610 * Fixed a channel ID update bug in JOIN command reply. Do
2611 not directly upgrade the ID but call the function
2612 silc_idlist_replace_channel_id if the ID was changed.
2613 Affected file silcd/command_reply.c.
2615 * Fixed memory leaks from command calling if it would fail.
2616 Affected file silcd/command.c.
2618 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2620 * Applied patches from cras:
2622 Memory leak fixes around libaries, irssi window resize fix,
2623 new silclist.h and silcdlist.h, all extern inline changed to
2626 * Removed dotconf from lib/dotconf, not needed anymore.
2628 * Removed TRQ from lib/trq, not needed anymore.
2630 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2631 with server connections. Later this will be configurable
2632 in config file after new config file is done. Affected file
2635 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2637 * Fixed a crash in server related to channel announcements.
2638 Affected file silcd/server.c.
2640 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2642 * Fixed memory leaks in silc_server_create_new_channel*
2643 functions. Affected file silcd/server.c.
2645 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2646 which ID was changed. This way the router will send the
2647 user list for the channel again, and server won't be in
2648 desync in some rare circumstances. Affected file is
2649 silcd/packet_receive.c.
2651 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2653 * Check for NULL socket pointer in the function
2654 silc_server_packet_send_to_channel_real. Affected file
2655 silcd/packet_send.c.
2657 * Fixed the BAN notify handling to correctly remove ban
2658 list. Affected file silcd/packet_receive.c.
2660 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2662 * Fixed some header addition to Toolkit distribution in
2663 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2665 * Added lib/silcclient/client_ops_example.h as an template
2666 file for application programmers to quickly start using
2667 the SilcClientOperation functions in their application.
2668 Updated the lib/silcclient/README as well to tell about this
2669 nice file made available.
2671 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2673 * Call silc_server_remove_from_channels when removing client
2674 entry when NO_SUCH_CLIENT_ID was received. Affected file
2675 is silcd/command_reply.c.
2677 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2679 * Added server & router operator statistics updating. Affected
2680 file silcd/packet_receive.c and silcd/command.c.
2682 * Fixed the SERVER_SIGNOFF notify handling on normal server
2683 not to save the history information for clients. Same was
2684 fixed earlier in remove_clients_by_server function, but not
2685 here. Affected file silcd/packet_receive.c.
2687 * Raised the default connection-retry count from 4 to 7 in
2688 server. Affected file silcd/server.h.
2690 * Cancel any possible reconnect timeouts when we start the
2691 key exchange. Affected file silcd/server.c.
2693 * Do not reconnect on connection failure when SCONNECT was
2694 given. Affected files silcd/server.[ch].
2696 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2698 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2700 * Fixed the NICK command to always give the unformatted
2701 nickname to the one giving the NICK command. If unformatted
2702 nickname is cached already it will be formatted and the
2703 local entry will always get the unformatted nickname.
2704 Affected file lib/silcclient/idlist.c.
2706 * Fixed some double frees from client library commands.
2707 Affected file is lib/silcclient/command.c.
2709 * Fixed CUMODE command in server to assure that no one can
2710 change founder's mode than the founder itself, there was a
2711 little bug. Affected file silcd/command.c.
2713 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2715 * Removed the SilcClientCommandDestructor from the client
2716 libary, it is not needed anymore. Affected files are
2717 lib/silcclient/silcapi.h, command[_reply].[ch],
2718 client_notify, idlist.c.
2720 * Fixed GETKEY command to first resolve client, and then
2721 resolve the server only if the client was not found, instead
2722 of resolving both at the same time. Affected file is
2723 lib/silcclient/command.c.
2725 * Added silc_client_start_key_exchange_cb and lookup the
2726 remote hostname and IP address before starting the key
2727 exchange with server. The affected file is
2728 lib/silcclient/client.c.
2730 * The server's public key is now saved using the IP address
2731 of the server and not the servername for the filename.
2732 The hostname public key filename is checked as an fall back
2733 method if the IP address based filename is not found.
2735 Fixed the GETKEY command to save the fetched server key
2736 in correct filename.
2738 Print the remote server's hostname now when new key is
2739 received during connection process. Affected file is
2740 irssi/src/silc/core/client_ops.c.
2742 * Return always our own public key to the client if it asks
2743 for it with GETKEY command. Affected file silcd/command.c.
2745 * Removed the use_auto_addr variable from default config
2746 file since it was in wrong section. Affected file is
2749 * Fixed TOPIC_CHANGE notification to not route it when it
2750 was sent using silc_server_send_notify_to_channel function.
2751 Affected file silcd/command.c.
2753 * Fixed silc_server_send_notify_kicked to send the kicker's
2754 Client ID also, it was missing. Affected files are
2755 silcd/command.c, silcd/packet_send.[ch].
2757 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2759 * Do not save client history information in SERVER_SIGNOFF.
2760 Fixes the bug in normal server that it does not detect
2761 the client becoming valid after the server becomes back
2762 online. Affected file silcd/server_util.c.
2764 * Added `sock_error' field into the SilcSocketConnection
2765 context. When error occurs during socket operation (read
2766 or write) the error is saved. Added also new function
2767 silc_socket_get_error to return human readable socket error
2768 message. Affected files are lib/silcutil/silcsockconn.[ch],
2769 lib/silcutil/unix/silcunixsockconn.c, and
2770 lib/silcutil/win32/silcwin32sockconn.c.
2772 * The server now prints the socket error message in the
2773 signoff for client. Affected file silcd/server.c.
2775 * Fixed the `created' channel information sending from router
2776 to server in JOIN command. Checks now whether the channel
2777 really was created or not and set it according that.
2779 Fixed the JOIN command to use the client entry's current
2780 ID during the joining procedure instead of the one it sent
2781 in the command (it is checked though), since it can change
2782 between the packet processing and command processing, and
2783 would just case unnecessary pain in the client end. Affected
2784 file silcd/command.c.
2786 * Fixed a channel key payload sending to use correct channel
2787 ID when the server was forced to change the channel's ID by
2788 router. Router sent the key payload with the old Channel ID.
2789 Affected file silcd/packet_receive.c.
2791 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2793 * Call silc_server_save_channel_key only if the key payload
2794 was provided in the JOIN command's command reply. Affected
2795 file silcd/command_reply.c.
2797 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2799 * Fixed silc_mp_sizeinbase to return the value correctly with
2800 MPI. Affected file lib/silcmath/mp_mpi.c.
2802 * Fixed the stop_server signal to correctly stop the scheduler
2803 and gracefully stop the server when SIGTERM or SIGINT signals
2804 are received. Affected file silcd/silcd.c.
2806 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2808 * Simple handling of TERM and HUP signals. Also added some log
2809 flushing call around. Affected file is
2812 * Fixed small bugs in silclog.c. Now buffering output will take
2813 effect after 10 seconds since startup: This will ensure that
2814 no important startup messages are lost. Also output redirection
2815 will preserve original format ([Date] [Type] message).
2816 Affected file is lib/silcutil/silclog.c.
2818 * Added two options to the config file, in the logging section:
2819 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2820 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2822 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2824 * Do not print the warning about log files not being initialized
2825 more than once to avoid excess logging. Affected file is
2826 lib/silcutil/silclog.c.
2828 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2829 the SIM copying in make install in Makefile.am.pre.
2831 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2833 * Rewritten silclog APIs. Globally interesting changes follows:
2834 silc_log_set_files() changed to silc_log_set_file().
2835 silc_log_set_callbacks() changed to silc_log_set_callback().
2836 ROBOdoc documented silclog header file.
2837 SilcLogCb now returns bool to wether inihibit the default
2838 handler or not (to keep the old behaviour return always TRUE).
2839 The new APIs should also fix the problem of the
2840 silcd_error.log file that was written in the current directory.
2843 Log files streams will remain opened after silc_log_set_file()
2844 call, means less CPU usage notably on high traffic servers.
2845 File streams are now full buffered, and flushed to the disk
2846 every 5 minutes, lesses HD activity and CPU usage.
2847 Messages can be redirected, allowing admins to configure
2848 one single logfile for all server messages.
2849 the silc_log_quick global variable to activate fast-logging.
2850 Affected files lib/silcutil/silclog.[ch]
2852 * Changed some code to conform new silclog APIs. Affected
2853 files are doc/example_silcd.conf.in, silcd/server.c
2854 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2857 * Fixed a memory leak that could occur in some situations.
2858 Affected file silcd/serverconfig.c.
2860 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2862 * Added the silc_client_del_client to remove the client from
2863 all channels as well. Affected file lib/silcclient/idlist.c.
2865 * Fixed the client library to correctly remove the client
2866 from all channels when the client entry is being destroyed.
2867 Affected file lib/silcclient/client_notify.c, command.c.
2869 * Added auto-nicking support to the client library. If the
2870 applicatio now sets client->nickname it will be sent to the
2871 server after connecting by the library. This way for example
2872 SILCNICK (or IRCNICK) environment variables will have effect
2873 and always change the nickname automatically to whatever
2874 it is wanted. Affected file lib/silcclient/client.[ch].
2876 * Renamed silc_server_command_bad_chars to the
2877 silc_server_name_bad_chars and moved it to the
2878 silcd/server_util.[ch]. Added also new function
2879 silc_server_name_modify_bad to return nickname that
2880 includes bad characters as new nickname without those
2881 bad characters. This check and modify is now used in
2882 silc_server_new_client when the username is initially set
2883 as nickname, so it must be checked to be valid nickname.
2884 Affected file silcd/packet_receive.c.
2886 * The nickname length is now taken from the packet for real
2887 and not trusted to strlen() since it clearly can return
2888 wrong length for nickname including bad characters. This
2889 also applies to channel names. Affected file silcd/command.c.
2891 * Removed the lib/silcsilm/modules directory. Modules are now
2892 compiled into the lib/silcsim. Fixed the copying of the
2893 modules to follow symbolic links in Makefile.am.pre.
2895 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2897 * Fixed silc_string_regexify list creation. Fixes bugs with
2898 BAN and INVITE commands in server. The affected file is
2899 lib/silcutil/unix/silcunixutil.c.
2901 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Removed the command destructor entirely from the server's
2904 command and command reply routines. It is not needed, and
2905 its usage was buggy and caused crashes. Affected files are
2906 silcd/command[_reply].[ch].
2908 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Cancel protocol and NULL sock->protocol if timeout
2911 occurred during protocol. Affected file silcd/server.c.
2913 * Cancel protocol timeouts always before calling the final
2914 callback, to assure that after final callback is called
2915 no other state will be called for the protocol anymore.
2916 Affected file silcd/protocol.c.
2918 * Print error log if incoming connection configuration could
2919 not be found. Affected file silcd/server.c.
2921 * Fixed JOIN command to correctly save the founder mode
2922 to the client on normal SILC server, when the channel
2923 was created by the router. Affected file silcd/command.c.
2925 * Fixed LIST command (hopefully) to send correct reply
2926 packets. Affected file silcd/command.c.
2928 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2930 * The silc_packet_receive_process now returns FALSE if the
2931 read data was invalid packet, and TRUE if it was ok.
2933 The server now checks that if unauthenticated connection
2934 sends data and its processing fails the server will close
2935 the connection since it could be a malicious flooder.
2937 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2939 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Make sure the warning about error opening a log file is
2942 printed only once and not everytime it fails (produces
2943 too much useless log). Affected file lib/silcutil/silclog.c.
2945 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2947 * Made the silc_server_daemonise() function more readable.
2948 Affected file silcd/server.c.
2950 * Pid file is now optional, the user may comment it out from
2951 the config file. Removed define SILC_SERVER_PID_FILE, we
2952 don't need a default any longer. Affected file
2953 configure.in.pre, lib/Makefile.am.pre.
2955 * Make some use of the pid file. The server now dies at startup
2956 if it detects a valid pid file on his path. The server would
2957 die anyway in this circumstance, because of the bind() failure.
2958 Affected file silcd/silcd.c.
2960 * No longer compiling lib/dotconf.
2962 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2964 * Fixed JOIN command parsing not to crash. Affected file
2965 lib/silcclient/command.c.
2967 * Fied the NICK_CHANGE notify to add the new client entry
2968 even it is resolved. This removes an <[unknown]> nick
2969 thingy bug in the client. Affected file is
2970 lib/silcclient/client_notify.c.
2972 * Do not try to allocate 0 bytes (efence does not like it)
2973 in lib/silccore/silccomand.c when encoding payload.
2975 * Do not take IRCNICK as nickname in Irssi SILC client since
2976 it is not possible to set nickname before hand connecting
2977 the server (TODO has an entry about adding auto-nicking
2980 * Changed the silc_server_command_pending to check whether
2981 there already exists an pending entry with the specified
2982 command, command identifier and pending callback. This is
2983 to fix IDENTIFY and WHOIS related crashes that may register
2984 multiple pending commands with same identifier. Affected
2985 file silcd/command.c.
2987 * Fixed the server to reconnect to the router even if it
2988 was already reconnecting and EOF was received. This to
2989 fix a possibility that the server wouldn't ever try to
2990 auto-reconnect to the router. Affected file silcd/server.c.
2992 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Fixed the server's password authentication to use the
2995 length of the locally saved password, and not the one
2996 sent in the packet. Affected file silcd/protocol.c.
2998 * Fixed same password authentication problem in the
2999 Authentication Payload handling routines in
3000 lib/silccore/silcauth.c.
3002 * Yet another password authentication problem fixed with
3003 channel password handling in silcd/command.c.
3005 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * If first character of string in silc_parse_userfqdn is '@'
3008 then do not parse it. Affected file is
3009 lib/silcutil/silcutil.c.
3011 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3013 * Fixed minor bug in IDENTIFY command reply sending, which
3014 caused various weird problems during JOIN when it was
3015 resolving names for users. Affected file silcd/command.c.
3017 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Fixed the IDENTIFY command reply sending to chech better valid
3020 clients. It was possible to send incomplete list of replies.
3021 Affected file silcd/command.c.
3023 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Added silc_client_command[s]_[un]register functions now to
3026 dynamically register the commands in client library. Removed
3027 the static table of commands. This allows the client library
3028 to call commands without causing the application to know about
3029 what commands library has called.
3031 Removed the INFO command reply kludge to detect when the command
3032 was called by library. Now library use its own command reply
3033 function for INFO command.
3035 Added function silc_client_command_call to call a command.
3036 Application can use it to call command, not access the structure
3039 Now all commands that are sent by the client library (not
3040 explicitly sent by application) use own command reply functions.
3042 Affected files around lib/silcclient/ and in
3043 irssi/src/silc/core/.
3045 * Fixed the WHOIS command reply sending to chech better valid
3046 clients. It was possible to send incomplete list of replies.
3048 Fixed the WHOIS and IDENTIFY to send the request to router
3049 if normal server did not do it and did not find any results.
3051 Affected file silcd/command.c.
3053 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Moved the internal data from SilcClient context into its
3056 own file, not accesible to application. Affected files
3057 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3058 and other files in client library.
3060 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3062 * Added doc/examples installation target in Makefile.am.pre.
3065 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3068 commands the found client entry will be removed from the
3069 cache, after notifying application about the error. Affected
3070 file lib/silcclient/command_reply.c.
3072 * Changed the /MSG to check for exact nickname user gave, and
3073 not let `nick' match `nick@host' if it is only one found. Now,
3074 user must type the exact nickname (like nick@host2) even if
3075 there are no more than one same nicks found. This is to avoid
3076 a possibility of sending nickname to wrong nickname since
3077 `nick' could match `nick@host'. Affected file is
3078 irssi/src/core/silc-servers.c.
3080 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Do not print "you are now server operator" or similar when
3083 giving /away command. Affected files are
3084 irssi/src/silc/core/client_ops.c, silc-servers.h.
3086 * Made the silc_server_command_pending_error_check to send
3087 the same command reply payload it received back to the
3088 original sender of the command. This way all arguments
3089 that was received by the server will be received by the
3090 client too. Affected file silcd/command.c.
3092 * Added the silc_idcache_add to return the created cache entry
3093 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3095 * Add global clients to expire if they are not on any channel.
3096 This is because normal server will never know if they signoff
3097 if they are not on any channel. The cache expiry will take
3098 case of these entries. This is done by normal servers only.
3099 The affected files are silcd/command_reply.c,
3100 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3102 * If server receives invalid ID notification for WHOIS or
3103 IDENTIFY and the ID exists in the lists, it is removed.
3104 Affected file silcd/command_reply.c.
3106 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3107 in client then client entry that it matches is searched and
3108 the nickname is printed on the screen for user. Affected
3109 file irssi/src/silc/core/client_ops.c.
3111 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Use cache entry expire time in the LIST command reply to
3114 purge old entries from the cache after the LIST command
3115 reply has been received. This way we don't have non-existent
3116 entries in the cache for too long. Affected file is
3117 silcd/command_reply.c.
3119 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * If we are normal server, and we've not resolved client info
3122 in WHOIS or IDENTIFY from router, and it is global client,
3123 we'll check whether it is on some channel. If it is not
3124 then we cannot be sure about its validity and will resolve it
3125 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3126 file silcd/command.c.
3128 * Search channel by name (if possible) rather than by ID
3129 in IDENTIFY command's command reply. Affected file is
3130 silcd/command_reply.c.
3132 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3135 Updated specs and implemented it. Affected file silcd/command.c,
3136 silcd/packet_send.c and silcd/packet_receive.c.
3138 * Implemented the <founder auth> payload handling in the JOIN
3139 command. If provided all conditions for channel joining
3140 except requirement to provide correct passphrase can be
3141 overrided by the channel founder. Updated the protocol specs.
3142 Affected file silcd/command.c.
3144 Added support for founder auth in JOIN command in client
3145 library. Fixed the parsing of the JOIN command now to support
3146 all options as they should be. The affected file is
3147 lib/silcclient/command.c.
3149 * Optimized the WHOIS and IDENTIFY commands to send the request
3150 to router only if it includes nicknames or other names. If
3151 they include only IDs then check the local cache first before
3152 routing. Affected file is silcd/command.c.
3154 * Added channels topic announcements. Affected file is
3155 silcd/packet_receive.c and silcd/server.c.
3157 * Fixed the silc_server_send_notify_topic_set to really destine
3158 the packet to channel. Affected file silcd/packet_send.c.
3160 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3161 library. Affected file lib/silcclient/client_notify.c.
3163 * Added UMODE announcements. Affected file silcd/server.c.
3165 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3167 * Memory leak fixes in:

3174 lib/silccore/silccommand.c
3175 lib/silccore/silcidcache.c
3180 * ROBOdoc documented the lib/silcske/groups.h file and a
3181 bit changed the interface for better.
3183 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3185 * Update the client entry context in the ID cache after
3186 nick change. Affected file lib/silcclient/command.c.
3187 Fixes the CUMODE command when regaining founder privileges,
3188 and a little WHOIS problem.
3190 * Fixed silc_net_gethostbyname to correctly call the
3191 inet_ntop. Affected file lib/silcutil/silcnet.c.
3193 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3195 * Added IPv6 support checking to the configure.in.pre, added
3196 also --enable-ipv6 option to override the check. Affected
3197 file configure.in.pre.
3199 * The silc_thread_create now calls the start function
3200 directly if threads support is not compiled in. Removes
3201 ugly #ifdef's from generic code. Affected files are
3202 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3204 * Added silc_net_gethostby[name/addr]_async to asynchronously
3205 resolve. Affected files are lib/silcutil/silcnet.[ch].
3207 * Added support for rendering IPv6 based server, client and
3208 channel IDs. Affected file lib/silcutil/silcutil.c.
3210 * Added support for creating IPv6 based server IDs. Affected
3211 file is silcd/serverid.c.
3213 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3215 * Added silc_net_gethostby[addr/name] into the
3216 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3217 routines. Added silc_net_is_ip[4/6]. Affected file is
3218 lib/silcutil/unix/silcunixnet.c. All routines that take
3219 address as argument now supports both IPv4 and IPv6 addresses.
3221 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3223 * Fixed LIST command reply sending in server. Affected file
3226 * Server now sends the kicker's client ID in the KICK notify
3227 to the kicked client. Affected file silcd/command.c.
3229 * The client library now parses the kickers client ID and
3230 UI displays it. Affected files lib/silcclient/client_notify.c
3231 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3233 * Made all payload parsing function prototypes consistent.
3234 They all take now const unsigned char * and uint32 pair as
3235 the payload data instead of SilcBuffer. Changes all around
3236 the source tree. Other unsigned char* -> const unsigned char*
3237 changes around the tree as well.
3239 * Optimized SFTP client and server packet sending not to
3240 allocate new buffer for each packet but to recycle the
3241 first allocated buffer. Affected files are
3242 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3244 * Optimized the SFTP client to use SilcList instead of
3245 SilcDList for requests, because it is faster. Affected file
3246 is lib/silcsftp/sftp_client.c.
3248 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3249 into lib/silccore/silcid.[ch].
3251 Renamed silcpayload.[ch] into silcargument.[ch].
3253 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * If client entry is deleted with active key agreement
3256 session, abort the session.
3258 The silc_client_abort_key_agreement now calls the completion
3259 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3261 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3264 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3266 * Don't use __restrict in older GCC's. Affected file is
3267 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3269 * silc_net_localhost now attempts to reverse lookup the
3270 IP/hostname. Affected file lib/silcutil/silcnet.c.
3272 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3273 command. It can be used to gain founder privileges at
3274 the same time when joining the channel.
3276 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3277 kicker's client ID as well. Updated protocol specs.
3279 Defined that the server must send SILC_COMMAND_IDENTIFY
3280 command reply with error status to client who sent
3281 private message with invalid client ID.
3283 Updated the protocol specification.
3285 * Added silc_server_send_command_reply to send any
3286 command reply. Affected file silcd/packet_send.[ch].
3288 * Added silc_id_payload_encode_data to encode ID payload
3289 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3291 * The server now send IDENTIFY command reply with error
3292 status if client ID in private message is invalid. Affected
3293 file silcd/packet_receive.c.
3295 * Save the server key file with server's IP address in
3296 the filename instead of hostname. The affected file is
3297 irssi/src/silc/core/client_ops.c.
3299 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3301 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3304 * Added libtool support for compiling shared objects in
3305 lib/silcsim. Affected file configure.in.pre and
3306 lib/silcsim/Makefile.am. Original patch by cras.
3308 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3310 * Pid file configuration, and server's config file fixes
3311 patch by toma. Updated CREDITS file.
3313 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3315 * Fixed silc_client_channel_message to not try to decrypt
3316 the message twice if it resolved the destination client
3317 information. This could cause of dropping one channel
3318 message. Affected file lib/silcclient/client_channel.c.
3320 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3323 lib/silcclient/client.c. This function is used when the SILC
3324 Client is run under some other scheduler, or event loop or
3325 main loop. On GUI applications, for example this may be
3326 desired to used to run the client under the GUI application's
3327 main loop. Typically the GUI application would register an
3328 idle task that calls this function multiple times in a second
3329 to quickly process the SILC specific data.
3331 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3333 * Fixed silc_server_drop() for dropping the supplementary
3334 groups as well, this could cause a security hole on some
3337 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3339 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3342 * Write PID file after dropping privileges. Added -F option
3343 to run server on foreground. A patch by debolaz.
3344 Affected files silcd/server.c, silcd/silcd.c.
3346 * Fixed MOTD to return the MOTD file server name. Affected
3347 file silcd/command.c.
3349 * Added INFO command reply handling to the Irssi SILC Client.
3350 Affected file irssi/src/silc/core/client_ops.c.
3352 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Fixed the silc_idcache_list_* routines to really support
3355 the dynamic list. Fixes a crash. Affected file is
3356 lib/silccore/silcidcache.c.
3358 * Fixed the LIST command reply to really call LIST command's
3359 pending callbacks. Affected file silcd/command_reply.c.
3361 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Update conn->local_entry->nickname after giving NICK
3364 command. Affected file lib/silcclient/command.c.
3366 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3368 * Added the [pid] option to the silcd configuration file
3370 Affected files: serverconfig.[ch] and silcd.c
3372 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Save fingerprint in WHOIS command reply in server.
3375 Affected file silcd/command_reply.c.
3377 * Fixed NICK commands pending callback registration.
3378 Affected file lib/silcclient/command.c.
3380 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Use ++server->cmd_ident when sending commands in server,
3383 instead of random number. Affected file silcd/command.c.
3385 * Fixed GETKEY command reply to call actually GETKEY pending
3386 command callbacks. Affected file silcd/command_reply.c.
3388 * A bit stricter check for nicknames. Check for same nickname
3389 in NICK command also. Affected file silcd/command.c.
3391 * Do not call INFO command everytime client ID changes, only
3392 during first connecting. Affected file lib/silcclient/client.c.
3394 * Set the new nickname only after successful command reply for
3395 NICK command is returned by server. Affected file
3396 lib/silcclient/command.c.
3398 * Remove nicknames from nicklist during server_signoff notify.
3399 Should fix /NAMES bit more. The affected file is
3400 irssi/src/silc/core/silc-channels.c.
3402 * Added `fingerprint' field to the SilcIDListData in the
3403 silcd/idlist.h to hold the fingerprint of the client's
3406 Send the fingerprint of the client's public key in WHOIS
3409 Affected files silcd/command.c, and silcd/idlist.[ch].
3411 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3412 create fingerprint from given data.
3414 * Show the fingerprint of the client's public key in WHOIS.
3415 Affected files irssi/src/module-formats.[ch] and
3416 irssi/src/silc/core/client_ops.c.
3418 * Format the multiple same nicknames also during JOIN and
3419 NICK_CHANGE notifys. Affected file is
3420 lib/silcclient/client_notify.c.
3422 * Do not print error on screen for invalid private message
3423 payload since it can come if someone is sending private
3424 messages with wrong key. Affected file
3425 lib/silccore/silcprivate.c.
3427 * Fixed multiple concurrent /PING crash. Affected file
3428 lib/silcclient/command.c.
3430 * Changed the wrong ID encoding. All IP addresses must be
3431 in MSB first order in encoded format. They were encoded
3432 wrong and was in LSB format. Affected files are
3433 silcd/serverid.c, lib/silcutil/silcutil.c.
3435 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3437 * Call the `connect' client operation through the scheduler
3438 in case of error. Affected file lib/silcclient/client.c.
3440 * Call the `failure' client operation even if the error
3441 occurred locally during a protocol. Affected file is
3442 lib/silcclient/protocol.c.
3444 * Added support of sending LIST command to router from normal
3445 server. This way normal server can get list of all channels
3446 in the network too. Fixed the channel list sending in the
3447 server too. Affected files are silcd/command.c, and
3448 silcd/command_reply.[ch].
3450 * Added silc_server_update_channels_by_server and
3451 silc_server_remove_channels_by_server. They are used during
3452 disconnection of primary router and in backup router protocol.
3453 Affected file silcd/server_util.[ch], silcd/server.c and
3454 silcd/server_backup.c.
3456 * Fixed channel adding to global list in IDENTIFY command
3457 reply in server. Affected file silcd/command_reply.c.
3459 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * If the incoming packet type is REKEY or REKEY_DONE process
3462 that packet always synchronously. Fixes yet another MAC
3463 failed error on slow (dialup) connections. Affected file
3464 lib/silcclient/client.c and silcd/server.c.
3466 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Call check_version SKE callback for initiator too. Affected
3469 file lib/silcske/silcske.c.
3471 * Implemented fix for security hole found in the SKE that was
3472 fixed in the specification few days back; the initiator's
3473 public key is now added to the HASH value computation.
3474 Added backwards support for the old way of doing it too, for
3475 old clients and old servers. Affected file is
3476 lib/silcske/silcske.c.
3478 * Enabled mutual authentication by default in SKE. If initiator
3479 is not providing mutual authentication the responder will
3480 force it. This will provide the proof of posession of the
3481 private key for responder. The affected files are
3482 lib/silcclient/protocol.c and silcd/protocol.c.
3484 * Do not cache anymore the server's public key during SKE.
3485 We do mutual authentication so the proof of posession of
3486 private key is done, and if the server is authenticated in
3487 conn auth protocol with public key we must have the public
3488 key already. Affected file silcd/protocol.c.
3490 * Added new global debug variable: silc_debug_hexdump. If
3491 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3492 file lib/silcutil/silclog.[ch].
3494 * Fixed compilation warning due to char * -> const char *.
3495 Affected files lib/silcutil/silcnet.h, and
3496 lib/silccore/silcauth.[ch].
3498 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Fixed CMODE command when new channel key was created. If
3501 the creation failed the old key was removed. Next time giving
3502 same command would crash the server since the old key was
3503 freed already. Affected file silcd/command.c.
3505 * Fixed the silc_server_announce_get_channels to not crash
3506 on reconnect. Affected file silcd/server.c.
3508 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Added silc_log_set_debug_string function to set a regex
3511 string to match for debug output. Only the function names,
3512 or filenames matching the given debug string is actually
3513 printed. This way it is possible to filter out those debug
3514 strings that user is not interested in.
3516 Fixed a bug in silc_string_regexify.
3518 Affected files lib/silcutil/silclog.[ch], and
3519 lib/silcutil/unix/silcunixutil.c.
3521 * Changed the -d options in both server and Irssi SILC client
3522 to take the debug string as argument. Affected files
3523 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3525 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Added silc_hash_babbleprint to create a Bubble Babble
3528 Encoded fingerprint. The encoding is developed by Antti
3529 Huima (draft-huima-babble-01.txt), and it creates human
3530 readable strings out of binary data. Affected file
3531 lib/silccrypt/silchash.[ch].
3533 * Print the babble print now in addition of fingerprint as well
3534 in Irssi SILC client. Affected files are
3535 irssi/src/fe-common/silc/module-formats.[ch],
3536 irssi/src/fe-common/silc/core/client_ops.c.
3538 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Fixed a security problem found in SKE. The initiator's
3541 public key too is now added to the HASH hash value creation
3542 which is signed by the responder to create the SIGN value.
3543 This will prevent anyone in the middle to lie to the responder
3544 about the initiator's public key. If this is done now, the
3545 man in the middle will get caught. Updated the protocol
3548 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Better installation directory handling. Configure module
3551 paths and other paths automatically to example_silc* files
3552 in doc/. A patch by toma.
3554 * Fixed compiler warning from MPI library, and from SILC RNG.
3557 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3558 It can be configured with ./configure. A patch by toma.
3560 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Find correct make to use in prepare-clean. A patch by
3563 toma. Affected file prepare-clean.
3565 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3567 * Added irssi variables use_auto_addr, auto_bind_ip,
3568 auto_bind_port and auto_public_ip.
3570 * Changed the interface for silc_client_send_key_agreement
3571 in lib/silcclient/silcapi.h
3575 irssi/src/silc/core/silc-core.c
3577 lib/silcclient/silcapi.h
3578 irssi/src/silc/core/silc-channels.c
3579 lib/silcclient/client_keyagr.c
3582 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3584 * Added silc_pkcs_public_key_compare to compare two
3585 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3587 * Check that the client who set the founder mode on the
3588 channel is the same client that is giving the founder
3589 mode to itself. It is done by comparing the saved public
3590 key (it is saved even in the authentication is passphrase).
3591 Affected file silcd/command.c.
3593 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Do not process packet for disconnected socket connection.
3596 Affected file lib/silccore/silcpacket.c.
3598 * Process the DISCONNECT packet through scheduler in the
3599 client library. Affected file lib/silcclient/client.c.
3601 * Fixed the silc_client_packet_parse to not to increase
3602 the packet sequence number if the conn->sock and the
3603 current socket connection is not same. This can happen
3604 for example during key agreement when the conn includes
3605 multiple socket connections (listeners). Affected file
3606 lib/silcclient/client.c.
3608 * The sender of the file transfer request now provides also
3609 the pointer (listener) for the key exchange protocol. If
3610 the listener cannot be created then it sends empty key
3611 agreement and lets the receiver provide the listener.
3613 Added `local_ip' and `local_port' arguments to the
3614 silc_client_file_send. If they are provided they are used,
3615 if not then it will attempt to find local IP address, if
3616 not found or bind fails then the remote client will provide
3619 Affected files are lib/silcclient/client_ftp.c and
3620 lib/silcclient/silcapi.h.
3622 * Extended the FILE SEND command to support defining the
3623 local IP and port for key exchange listener. They are
3624 optional. Affected file irssi/src/silc/core/silc-servers.c.
3626 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Defined to WHOIS command reply the sending of fingerprint
3629 of the client's public key (if the proof of posession of the
3630 corresponding private key is verified by the server).
3631 Updated to the protocol specification.
3633 * Added support of receiving the client's public key's
3634 fingerprint in command reply in client library. Affected
3635 file is lib/silcclient/command_reply.c, and
3636 lib/silcclient/idlist.[ch].
3638 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3640 * Do not send over 128 chars long nickname to the server
3641 in NICK command. Affected file lib/silcclient/command.c.
3643 * Do not send over 256 chars long channel names to the server
3644 in JOIN command. Affected file lib/silcclient/command.c.
3646 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3648 * Assure that silc_server_close_connection cannot be called
3649 twice for same socket context. Affected file is
3652 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3654 * Send error message to application if opening file for
3655 writing during file transfer fails. Affected file is
3656 lib/silcclient/client_ftp.c.
3658 Remove all file transfer sessions for a client that we're
3659 removing from ID cache.
3661 Affected file is lib/silcclient/client_ftp.c.

3691 client library. Affected file lib/silcclient/client_prvmsg.c.
3693 * Do not actually remove the client directly from ID cache
3694 during SERVER_SIGNOFF, but invalidate it. This way we
3695 preserve the WHOWAS info for the client. Affected file
3696 silcd/server_util.c.
3698 * Fixed SERVER_SIGNOFF notify handling in the server. The
3699 server is now able to process incoming SERVER_SIGNOFF notify
3700 for a server that it doesn't even know about. It will remove
3701 the clients provided in the notify. Affected file
3702 silcd/packet_receive.c.
3704 * Check for partial packet in data queue after every packet that
3705 was found from the queue. Return and wait for more data if
3706 there is partial data in queue. Affected file is
3707 lib/silccore/silcpacket.c.
3709 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3717 * Check that newsize in silc_buffer_realloc is larger than
3718 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3720 * Added better monitor of file transfers. It now monitors
3721 key agreement protocol during the file transfer too. Added
3722 error reporting too. Affected files
3723 irssi/src/silc/core/silc-servers.c,
3724 irssi/src/fe-common/silc/module-formats.[ch].
3726 * Wrote a help file for FILE command.
3728 * Added silc_rng_global_get_byte_fast to get not-so-secure
3729 random data as fast as possible. Random data is read from
3730 /dev/urandom if available and from the SILC RNG if not
3731 available. It is used in padding generation. Affected file
3732 lib/silccrypt/silcrng.[ch].
3734 * All packets in client library are now processed synchronously.
3735 Optimized packet processing a lot. Affected file
3736 lib/silcclient/client.c.
3738 * All server connection packets are processing synchronously
3739 now in server, to optimize packet processing. Affected file
3742 * Include files are installed now only in Toolkit distribution
3743 if make install is given. Affected files: all Makefile.am's.
3745 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Assure that silc_client_notify_by_server_resolve does not
3748 resolve the client information multiple times. If it cannot
3749 be found by the first it cannot be found at all. Affected
3750 file lib/silcclient/client_notify.c.
3752 * Fixed WHOWAS command reply calling. Affected file
3753 lib/silcclient/command_reply.c.
3755 * Removed all references to silc_idlist_get_client from the
3756 Irssi SILC client since that call is internal call used by
3757 the library. The Irssi SILC client will use now client
3758 retrieval functions found in silcapi.h.
3760 * Fixed a bug in resolving nickname info before sending
3761 private message. It used freed memory. Affected file
3762 irssi/src/silc/core/silc-servers.c.
3764 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3766 * Assure my_channels statistics cannot go negative in server.
3767 Affected files silcd/server.c, silcd/server_util.c.
3769 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3783 * Added silc_net_localip to return local host's IP address.
3784 Affected file lib/silcutil/silcnet.[ch].
3786 * If key exchange or rekey protocol is active for a connection
3787 parse all packets syncronously since there might be packets
3788 in packet queue that we are not able to process without first
3789 processing packets before them. Affected file silcd/server,
3790 lib/silcclient/client.c.
3792 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3793 whether library should continue processing the packet.
3794 Affected file lib/silccore/silcpacket.h.

3840 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3841 is incomplete and is being resolved, it won't be resolved
3844 Make sure also that USERS command reply does not resolve
3845 twice information. Affected file is
3846 lib/silcclient/command_reply.c.
3848 Make sure that silc_client_get_clients_by_list does not
3849 resolve twice same information.
3851 * Check for valid client->id in the silc_server_free_client_data.
3852 Affected file silcd/server.c.
3854 * Fixed /GETKEY nick@server not to crash if the server entry
3855 is not found. Affected file lib/silcclient/command.c.
3857 * Fixed the silc_server_check_cmode_rights to check the
3858 requested modes correctly. Affected file silcd/command.c.

3863 Affected file silcd/command.c.
3865 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3867 * Call the silc_server_udpate_servers_by_server in the
3868 primary router that comes back online in the backup resuming
3869 protocol. Otherwise it routes packets wrong. Affected file
3870 silcd/server_util.[ch], silcd/server_backup.c.
3872 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3875 lib/silcutil/silcbuffmt.[ch].
3877 * Redefined the SILC packet header to include the padding
3878 length. Affected file lib/silccore/silcpacket.[ch].
3880 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3881 length for maximum padding up to 128 bytes). Affected
3882 file lib/silccore/silcpacket.h.
3884 * Removed all backwards support for old 0.5.x MAC thingies.
3885 The SILC packet header change makes it impossible to be
3886 backwards compatible.
3888 * Send the ENDING packet with timeout in the backup resuming
3889 protocol. This is to assure that all routers has connected
3890 to the primary router. Affected file silcd/server_backup.c.
3892 * Changed the RNG to take the first IV from random data. It
3893 used to take it from zero actually. Changed the RNG also
3894 to use /dev/urandom during session. /dev/random is used
3895 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3897 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3899 * Changed the SILC packet header to have the first two bytes
3900 (the packet length) encrypted. Affected files aroung the
3901 code tree, lib/silccore/silcpacket.[ch]. Removed the
3902 SilcPacketCheckDecrypt callback. It is not needed anymore
3903 since the silc_packet_receive_process will determine now
3904 whether the packet is normal or special.
3906 * Implemented the unidirectional MAC keys. Affected files
3907 lib/silcske/silcske.c, silcd/protocol.c and
3908 lib/silcclient/protocol.c.
3910 * Implemented the packet sequence number to the MAC computation.
3911 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3912 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3913 lib/silcclient/protocol.c.
3915 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3917 * Allow backup router to announce servers. All servers
3918 announced by backup router are added to the global list
3919 automatically. Update hte server's socket to our primary
3920 router also when backup router announces a server.
3921 Affected file silcd/packet_receive.c.
3923 * Do not update the client->router in the function
3924 silc_server_udpate_clients_by_server if the client is on
3925 global list. We might fail to find any specific server
3926 for locally connected clients and local cell clients. They
3927 should still use the `from' and not `to' as client->router.
3928 This fixes backup router resuming protocol. Affected file
3929 silcd/server_util.c.
3931 * Decrease channel statistics count only if the channel
3932 deletion worked. Affected files are silcd/server.c and
3933 silcd/server_util.c.
3935 * Added silc_server_update_servers_by_server to update origin
3936 of all server entries. Used during backup router protocol.
3937 Affected files silcd/server_util.[ch], silcd/server.c. and
3938 silcd/backup_router.c.
3940 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3941 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3942 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3943 lib/silccrypt/silchmac.c.
3945 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3947 * Assure that router cannot reroute the same channel message
3948 to the sender. Affected file silcd/packet_receive.c.
3950 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Made better checks that the channel message is not sent
3953 to the router it came from. Affected file is
3954 silcd/packet_send.c. Fixed memory leak too.
3956 * Announce informations for incoming router connection, but
3957 only after checking if it is replaced by backup router.
3958 Affected file silcd/packet_receive.c.
3960 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Fixed the backup resuming protocol to work in multiple
3963 router environment. Affected file silcd/server_backup.c.
3965 * Route packet only to one router in the function
3966 silc_server_packet_send_to_channel. Affected file is
3967 silcd/packet_send.c.
3969 * Fixed silc_server_send_notify_dest to set the broadcast
3970 flag. Fixed the silc_server_send_notify_topic to actually
3971 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3972 Affected file silcd/packet_send.c.
3974 * Changed the SFTP Filesystem interface. Changed the
3975 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3976 the filesystem operation function. The SilcSFTPFilesystem
3977 is now a context that is allocated by all filesystem allocation
3978 functions and it already includes the operations structure
3979 and filesystem specific context. It is given as argument
3980 now to the silc_sftp_server_start. This made the interface
3981 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3982 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3984 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Changed the backup router adding and getting interfaces
3987 in the server. The router that will be replaced by the
3988 specified backup router is now sent as argument. Affected
3989 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3992 * Added silc_net_addr2bin_ne to return the binary form of
3993 the IP address in network byte order. Affected files
3994 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3996 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Check for existing server ID in silc_server_new_server
3999 and in silc_server_connect_to_router_final and remove the
4000 old entry if it exists. Affected file silcd/packet_receive.c,
4003 * Send the channel message always to only one router, either
4004 in upstream or downstream. Affected file is
4005 silcd/packet_send.c.
4007 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4009 * Wrote the definition of the backup resuming protocol to the
4010 protocol specification.
4012 * Removed one redundant channel key generation from normal
4013 server during joining procedure. Removed one redundant
4014 channel key sending from server to router during joining
4015 procedure. Affected file silcd/command.c.
4017 * Made minor bugfixes to the backup router resuming protocol.
4018 Affected file silcd/server_backup.c, server.c.
4020 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4022 * Added --disable-asm configuration option. Affected files
4023 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4026 * Implemented the backup resuming protocol that is used to
4027 resume the primary router position in the cell after the
4028 primary router comes back online. Affected files
4029 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4030 and silcd/server_util.[ch].
4032 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4034 * Sleep two (2) seconds after sending QUIT command to server.
4035 Affected file lib/silcclient/command.c.
4037 * Assure that if outgoing data buffer is pending do not force
4038 send any data. Affected file silcd/packet_send.c.
4040 * Assure that if outgoing data buffer is pending do not force
4041 send any data. Affected file lib/silcclient/client.c.
4043 * Implemented the backup router support when the primary router
4044 goes down. The servers and routers can now use the backup
4045 router as new primary router without loosing connectivity.
4047 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4049 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4050 in the server to indicate disabled entry. All data read
4051 from the connection will be ignored and no data is sent
4052 for entry that is disabled. Affected files are
4053 silcd/idlist.h, silcd/server.c.
4055 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4057 * Created SFTP client and server test programs in the
4058 lib/silcsftp/tests directory.
4060 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Implemented memory filesystem (virtual filesystem) for
4063 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4066 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4068 * Implemented the SFTP (SSH File Transfer Protocol) to the
4069 lib/silcsftp. It includes SFTP client and SFTP server
4072 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4074 * Moved lib/silccore/silcprotocol.[ch] to the
4075 lib/silcutil library.
4077 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4078 take variable argument list pointer as argument. Affected
4079 file lib/silcutil/silcbuffmt.[ch].
4081 * Added silc_buffer_set function that is used to set data
4082 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4083 Affected file lib/silcutil/silcbuffer.h.
4085 * Changed various routines in the core library to use the new
4086 silc_buffer_set instead of allocating new buffer only for
4089 * Added 64-bit value formatting and unformatting support to the
4090 silc_buffer_[un]format routines. Affected file is
4091 lib/silcutil/silcbuffmt.[ch].
4093 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4094 to includes/bitmove.h.
4096 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4098 * Fixed channel user mode saving in client library. Affected
4099 file lib/silcclient/command[_reply].c.
4101 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4103 * Defined the file transfer to the SILC Protocol. Added
4104 new packet type SILC_PACKET_FTP and defined File Transfer
4105 Payload. The mandatory file transfer protocol is SFTP
4106 (SSH File Transfer Protocol). Affected file in addition
4107 of the internet draft is lib/silccore/silcpacket.h.
4109 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4110 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4111 is used as part of backup router protocol when the primary
4112 router of the cell is back online and wishes to resume
4113 the position as primary router.
4115 * Redefined the MAC generation keys in the protocol. The
4116 same key is not used anymore in both direction. Both
4117 direction will now use different keys for sending and
4118 receiving. This fixes a potential security flaw. This
4119 change causes incompatibilities in the protocol.
4121 * Redefined also the MAC computation from the packet.
4122 An packet sequence number is now added to the MAC
4123 computation. This prevents possible replay attacks against
4124 the protocol. This change too causes incompatibilities
4127 Added `sequence' field to the SilcPacketContext to hold
4128 the current sequence number for the packet.
4130 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4132 * Added `created' field to the SilcIDListData in the file
4133 silcd/idlist.h to indicate the time when the entry was
4136 * Added `created' field to the SilcChannelEntry too. Affected
4137 file silcd/idlist.h.
4139 * Added `creation_time' aguments to all the announcement functions
4140 in the server. If it is provided then only the entries that
4141 was created after the provided time frame are actually
4142 announced. Affected file silcd/server.[ch].
4144 * The protocol says that the Channel ID's IP address must be
4145 based on the router's IP address. Added check for this in
4146 the silc_server_new_channel when processing incoming New Channel
4147 Payload. Affected file silcd/packet_receive.c.
4149 * Print out the correct version with --version in SILC client.
4150 Affected file irssi/src/silc/core/silc-core.c.
4152 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4154 * Fixed WHOWAS command to check for completnes of the client
4155 entry always, not just when the command is coming from client.
4156 Affected file silcd/command.c.
4158 * Added new function silc_server_packet_queue_purge to purge the
4159 outgoing data queue to the network. After the function returns
4160 it is guaranteed that the outgoing packet queue is empty.
4161 Affected file silcd/packet_send.[ch].
4163 * Purge the outgoing packet queue in the rekey protocol's final
4164 callback to assure that all rekey packets go to the network
4165 before quitting the protocol. Affected file silcd/server.c.
4167 * Added silc_client_packet_queue_parse as similar function as
4168 in server to the client library. The affected file is
4169 lib/silcclient/client.c.
4171 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4173 * Splitted silcd/server.c and created silcd/server_util.[ch]
4174 for utility functions.
4176 * Added new socket flag SILC_SF_DISABLED to indicate that the
4177 connection is open but nothing can be sent to or received from
4178 the connection. Affected file lib/silcutil/silsockconn.[ch].
4179 The checking for disabled socket is checked in the low level
4180 silc_socket_write and silc_socket_read functions.
4182 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4184 * Allow only nicknames and channel names that fits into the
4185 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4187 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4189 * When processing JOIN command reply in server check that if
4190 the channel exists in our global list we'll move it the local
4191 list. Affected file silcd/command_reply.c.
4193 * Fixed the check whether client is joined on the channel already
4194 in JOIN command. Affected file lib/silcclient/command.c.
4196 * Fixed the JOIN command reply to check whether the channel
4197 already exists. Affected file lib/silcclient/command_reply.c.
4199 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4201 * Added silc_ske_status_string to map the SKE error numbers
4202 to readable strings. The affected files are
4203 lib/silcske/silcske[_status].[ch].
4205 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4207 * Do not show the private channels on the WHOIS channel list
4208 as it is not allowed by the protocol. The affected file is
4211 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4213 * Assure that the packet length digged from the actual packet
4214 is something sensible in the silc_packet_decrypt_rest_special
4215 in lib/silccrypt/silcpacket.c.
4217 * Free and NULL the allocated pointer in silc_hmac_alloc if
4218 the HMAC allocation fails. The affected file is
4219 lib/silccrypt/silchmac.c.
4221 * Print the selected security properties to the log files in
4222 the server. Affected file silcd/protocol.c.
4224 * Add SKE's reference counter even if calling the completion
4225 callback manually. Otherwise it goes negative, although it
4226 does not cause any problems. The affected file is
4227 lib/silcske/silcske.c.
4229 * Remove the client entry with short timeout after giving the
4230 KILL command. Affected file lib/silcclient/command.c.
4232 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4233 case all found clients are already disconnected (WHOWAS would
4234 found them) in the server. Affected file silcd/command.c.
4236 * Update the last_receive (time of last data received) to be
4237 updated only when received private or channel message so that
4238 the idle time showed in WHOIS makes more sense.
4240 * Added boolean field `valid' in to the SilcClientEntry in the
4241 client library to indicate whether the entry is valid or not.
4242 This fixes the nickname change bug on channel when changing
4243 the nickname to be same than the old (like nick to Nick) the
4244 nickname formatter doesn't set the new nick anymore to Nick@host.
4245 Affected file lib/silcclient/idlist.[ch].
4247 * Now actually fixed the nickname changing on disconnection.
4248 Added new function silc_change_nick to the Irssi SILC Client.
4249 Affected file irssi/src/silc/core/client_ops.c,
4250 irssi/src/silc/core/silc-nicklist.[ch].
4252 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Check that the public key exists in the GETKEY command before
4255 trying to encode it. Affected file silcd/command.c.
4257 * Print some notifications on received public keys with GETKEY
4258 command in the Irssi SILC Client. Affected files are
4259 irssi/src/fe-common/silc/module-formats.[ch],
4260 irssi/src/silc/core/client_ops.c.
4262 * Use IDENTIFY command to resolve the server information in the
4263 GETKEY command instead of INFO command. Affected file
4264 lib/silcclient/command.c.
4266 * All command reply functions in the client library now calls
4267 the pending command reply callbacks even if an error has
4268 occurred. The server has done this a long time and now it was
4269 time to move the client library to this as well. Now all
4270 errors can be delivered back to the pending command reply
4271 callbacks if necessary. Affected files are
4272 lib/silcclient/command[_reply].[ch].
4274 * Change the nickname on disconnection back to the username
4275 because in reconnect the server will enforce it to it anyway.
4276 Affected file irssi/src/silc/core/silc-servers.c.
4278 * Fixed a config file parsing bug in the Irssi SILC client.
4279 Affected file irssi/src/silc/core/clientconfig.c.
4281 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4283 * When printing the channel mode on JOIN, verify that the
4284 channel key and channel's HMAC are valid. Affected file
4285 irssi/src/silc/core/client_ops.c.
4287 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4289 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4290 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4291 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4293 * Removed channel key rekey task deleting from the function
4294 silc_server_save_channel_key. Affected file silcd/server.c.
4295 Added explicit timeout task context instead that is used to
4296 delete the task if we are registering a new task before the
4297 new task has elapsed.
4299 * When channel key rekey occurs the client library now saves
4300 the old channel key for a short period of time (10 seconds) and
4301 is able to use it in case some is still sending channel
4302 messages encrypted with the old key after the rekey. Affected
4303 file lib/silcclient/[idlist.h|client_channel.c].
4305 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4307 * Added check to the silc_server_new_id_real to not accept
4308 new ID if it is the sender's own ID. Affected file is
4309 silcd/packet_receive.c.
4311 * Assure that we do not announce ourself or the one we've
4312 sending our announcements when we're router and are announcing
4313 servers to our primary router. Affected file silcd/server.c.
4315 * Fixed silc_server_command_identify_check_client to assemble
4316 correct WHOIS packet. It send corrupted WHOIS packet and
4317 caused problem with router to router connections. Affected
4318 file silcd/command.c.
4320 Fixed also silc_server_command_whois_check the same way
4321 as for the IDENTIFY command.
4323 * Added new SilcIDListStatus to the server in the SilcIDListData
4324 structure. The status now includes the current status of
4325 the entry (like registered, resolved etc.). Affected file
4326 silcd/idlist.[ch]. Defined a bunch of different status types
4327 as well. This replaced the old boolean registered field as well.
4329 Added resolve_cmd_ident field to the SilcClientEntry structure
4330 too so that if the entry is for example being resolved so
4331 another command may attach to the same pending command reply
4332 without requiring to resolve the same entry again. This concept
4333 should optimize the WHOIS and the IDENTIFY resolving under
4334 heavy load by taking away unnecessary resolving for entries
4335 that are being resolved already.
4337 Added support for adding multiple pending commands for one
4338 command idenfier. Affected file silcd/command[_reply].[ch].
4340 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4341 before deleting the data. Otherwise the hash table will have
4342 freed data in comparison functions. Affected file is
4343 silcd/command_reply.c.
4345 * Fixed silc_idlist_replace_client_id to add the new entry to
4346 the cache with NULL nickname. Otherwise there will be invalid
4347 memory as the nickname after the nickname is freed. Affected
4348 file silcd/packet_receive.c.
4350 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4351 saved into wrong slots because the previous number of entries
4352 was not taken into account. Affected file silcd/idlist.c.
4353 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4355 * If we are router and we receive JOIN notify to a channel that
4356 does not have any users then notified client is marked as the
4357 channel founder, as it is it. The affected file is
4358 silcd/packet_receive.c
4360 * Added to the extended hash table API's table_del_*ext functions
4361 the destructor as argument too, so that the caller can decide
4362 which destructor to use or whether to use destructor at all.
4363 Affected file lib/silcutil/silchashtable.[ch].
4365 * Fixed ID Cache purging. It actually deleted the entries from
4366 the hash table after the data was freed. The hash table ended
4367 up comparing freed memory. The affected file is
4368 lib/silccore/silcidcache.c.
4370 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * Fixed Irssi SILC client's KILL command's HELP syntax.
4374 * The USERS command now resolves the detailed user information
4375 if the userinfo field is missing. Affected file is
4376 lib/silcclient/command_reply.c.
4378 * Do not print error in silc_file_read if the read file does
4379 not exist. Just silently return NULL. Affected file is
4380 lib/silcutil/silcutil.c.
4382 * Fixed the silc_log_output to not wine about NULL filename
4383 and to not create some bogus " " filename. Affected file is
4384 lib/silcutil/silclog.c.
4386 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4388 * Fixed various printing bugs on the user interface in the
4389 Irssi SILC Client. Minor changes that were forgotten from
4392 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4394 * Fixed the configure.in.pre and the compilation and distribution
4395 environment to support the new autoconf 2.52. That version is
4396 now required to compile the CVS trunk.
4398 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4401 to generally parse user@fqdn format strings. Affected file
4402 lib/silcutil/silcutil.c.
4404 * Added nickname_format and nickname_force_format fields to the
4405 SilcClientParams structure. The first one defines the format
4406 for the nicknames that the library will enforce if the receives
4407 multiple same nicknames. The second one is boolean value and
4408 can be used to force the library to always enforce the format
4409 to the nicknames regardles whether there are multiple nicknames
4410 or not. This configurable formatting was employed to flexibly
4411 support accessing multiple nicknames from the user interface.
4412 The userinterface can now set the nicknames to what ever format
4413 they prefer. Affected file lib/silcclient/silcapi.h.
4415 Added function silc_client_nickname_format to the file
4416 lib/silcclient/idlist.c. It performs the nickname formatting.
4418 Added new field `hostname´ to the SilcClientEntry context.
4419 It holds the hostname of the client. Affected file is
4420 lib/silcclient/idlist.h.
4422 * Irssi SILC Client sets the nicknames in nick@hostn format.
4423 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4424 irssi/src/silc/core/silc-core.c.
4426 The WHOIS printing now also shows both the real nickname and
4427 the formatted nickname so that user knows how to access the
4428 user if there are multiple same nicknames cached. Affected
4429 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4430 printing formatting too to take the hostname now as a separate
4431 argument. The Affected file is
4432 irssi/src/fe-common/silc/modules-formats.[ch].
4434 * Changed the silc_client_get_clients_local to accept the formatted
4435 nickname as argument. It accepts the real nickname too but the
4436 formatted nickname can be used to find the true entry from
4437 multiple entries. Affected file lib/silcclient/silcapi.h and
4438 lib/silcclient/idlist.c.
4440 * Added nickname_format_parse field to the SilcClientParams.
4441 It is a callback function provided by the application to parse
4442 the nickname out of the formatted nickname string. The library
4443 calls it to get the nickname from the formatted string. Since
4444 the application generally knows better the format of the nickname
4445 string it parses it instead of the library, even though library
4446 encodes the formatted string. If the callback function is not
4447 provided then the library will use the string as is. The
4448 affected file is lib/silcclient/silcapi.h.
4450 * All the nickname strings passed to the client library in
4451 commands are now expected to be formatted nickname strings.
4452 If the command does not support the formatted nickname string
4453 it will assume that the sent string is the actual nickname.
4454 Affected file lib/silcclient/command.c.
4456 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4458 * Added public key authentication support to OPER and SILCOPER
4459 commands in the client library. Affected file is
4460 lib/silcclient/command.c.
4462 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4464 * Changed the get_auth_methdod client operation to be asynchronous.
4465 It can be async if the application resolves the authentication
4466 method from the server during the negotiation. Added new
4467 SilcGetAuthMeth completion callback that the application will
4468 call after resolving the authentication method.
4470 Added function silc_client_request_authentication_method that
4471 the application can use to resolve the authentication method
4472 from the server. Added also SilcConnectionAuthRequest callback
4473 that the library will call after the server has replied. The
4474 application can call this function if it does not know the
4475 current authentication method.
4477 Affected files are lib/silcclient/client.c and
4478 lib/silcclient/silcapi.h.
4480 * The Irssi SILC client now automatically resolves the authentication
4481 method incase any configuration information is not present (and
4482 currently there never is). The affected file is
4483 irssi/src/silc/core/client_ops.c.
4485 * Fixed public key authentication from the client library.
4486 Affected file lib/silcclient/protocol.c. Changed also the
4487 protocol specification about the public key authentication in
4488 the connection authentication protocol. The actual data to be
4489 signed is now computed with a hash function before signing.
4491 * Fixed the public key authentication from the server as well.
4492 Affected file silcd/protocol.c.
4494 * Removed the mlock()'s from the memory allocation routines.
4495 Affected file lib/silcutil/silcmemory.c. The ./configure does
4496 not check anymore for the mlock(). Affected file is
4499 * Fixed USERS command in server to allow the execution of the
4500 command for private and secret channels if the client sending
4501 the command is on the channel. Affected file silcd/command.c.
4503 * Fixed silc_client_get_clients_local to return the clients
4504 count correctly. It could return wrong value. Affected file
4505 lib/silcclient/idlist.c.
4507 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4509 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4510 types. The assembler optimizations seemed not to like 64-bit
4511 data types. The assmebler optimizations thus are now enabled
4512 also for BSD systems as opposed to only enable them for Linux.
4514 * Do not check for threads at all on BSD systems. Affected
4515 file configure.in.pre.
4517 * Removed -n and -h options from the Irssi SILC Client since
4518 they are not used in silc.
4520 * Fixed the prime generation to assure that the first digit
4521 of the generated random number is not zero since our conversion
4522 routines does not like number strings that starts with zero
4523 digit. If zero digit is seen the random number is regenerated.
4524 This caused some corrupted RSA keys when the zero first digit
4525 was met. Affected file lib/silcmath/silcprimegen.c.
4527 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4529 * Fixed WIN32 configuration in the ./configure script.
4530 Fixed to include xti.h on environments that has it.
4531 Patches by Carsten Ilchmann and andrew.
4533 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4535 * Changed the silc_id_create_client_id to be collision
4536 resistant. It is now assured that there cannot be created
4537 two same client ID's. I suspect that some weird bugs in
4538 the server were actually caused by duplicate Client IDs.
4539 Affected file silcd/serverid.[ch]. A router receiving
4540 new ID now also assures and informs the sending server
4541 if the ID caused collision.
4543 * Changed the silc_id_create_channel_id to also assure that
4544 there are no collisions.
4546 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4548 * Statement about ignoring the Mutual Authentication flag when
4549 performing rekey with PFS was a bit misleading. It is ignored
4550 if it was set in the initial negotiation, it cannot be even
4551 set in the rekey. Fixed in the ke-auth draft. Started the
4552 new versions of the protocol drafts in the doc/.
4554 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4556 * Fixed a bug in silc_client_command_identify_save when saving
4557 new channel information. The channel name was no duplicated
4558 and caused crash on exit. Affected file is
4559 lib/silcclient/command_reply.c.
4561 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4563 * Fixed the getkey command handling in the server. Send just
4564 empty OK reply to the sender if the key could not be fetched
4565 (but everything else was ok, like the key just was not available).
4566 Changed the public key parameter to optional in the protocol
4567 specs so that empty OK reply can be sent. Affected file
4570 Added a message to Irssi SILC client to tell to user if the
4571 server did not return a public key.
4573 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4575 * Fixed a channel key regeneration bug. It registered new
4576 timeout tasks exponentially until all system resources were
4577 used. Affected file silcd/server.c.
4579 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4581 * Added the SILC Document generator to the scripts/silcdoc.
4582 It can be used to generate the Toolkit Reference Manual out
4583 of the source tree. Internally it will also use the RoboDoc
4584 generator now imported in util/robodoc.
4586 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4588 * Added couple of return's in rekey protocol if error orccurred
4589 during the protocol. The execution must be terminated.
4590 Affected file silcd/protocol.c. Also, terminate the protocol
4591 always with timeout.
4593 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4595 * The client's Client ID was created initally from the wrong
4596 nickname (it could have been in format nick@host) in the
4597 silc_server_new_client. Affected file silcd/packet_receive.c
4599 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4601 * Added some SILC_LOG_ERROR's to various error conditions
4602 if client could not be added to ID cache. Affected files
4603 silcd/packet_receive.c and silcd/server.c.
4605 * When client's sock->user_data is freed, NULL also the
4606 client->router and client->connection pointers. Added check
4607 for these pointers being NULL to various places around the
4608 code. Affected file silcd/server.c.
4610 * Added client->data.registered == TRUE checks to various
4611 places around the code to assure that unregistered client's
4612 are not handled when it is not allowed. Affected file
4615 * Added `bool registered' fields to all
4616 silc_idlist_[server|client]_get_* routines to indicate whether
4617 the fetched client needs to be registered or not. Affected
4618 file silcd/idlist.[ch].
4620 * Add your own entry as registered to the ID cache in the
4621 server. Affected file server.c.
4623 * Fixed a bug in silc_server_new_server. The SilcServer was
4624 set as the new server's context instead of SilcServerEntry.
4625 This naturally caused some weird bugs.
4627 * Added "updated" field the SilcChannelEntry which indicates
4628 the time since the channel entry was last accessed. This
4629 can be used to determine whether it is necessary to
4630 announce the channel after backup resuming protocol.
4631 Affected files silcd/idlist.[ch].
4633 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4635 * Do not delete the channel rekey task when adding it
4636 for in silc_server_create_channel_key.
4638 * Changed the silc_server_create_channel_key to return
4639 TRUE or FALSE to indicate the success of the channel key
4642 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4644 * Fixed MSVC++ project files and added missing files to
4645 Makefiles under win32/.
4647 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4649 * Do not add TCP_NODELAY flag if the operating system
4650 does not have it defined. Affected files are
4651 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4653 * Fixed buffer overflow from Irssi SILC Client. Affected
4654 file irssi/src/fe-common/core/themes.c.
4656 * Fixed double free in client library in the file
4657 lib/silcclient/client.c when disconnecting from server.
4659 * Applied double free patch from cras to Irssi SILC client.
4660 Affected files irssi/src/core/[modules/expandos].c
4662 * Fixed the disconnection handling to Irssi SILC Client.
4663 The application must call silc_client_close_connection
4664 in ops->connect client operation in case of failure of
4665 the connection. Affected file is
4666 irssi/src/silc/core/client_ops.c.
4668 * Do not set sock->protocol to NULL in the function
4669 silc_client_close_connection after executing the protocol's
4670 final callback since the sock might not be valid anymore.
4671 Affected file lib/silcclient/client.c.
4673 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4675 * Do not enable SILC_THREADS if the linking with libpthread
4676 did not happen. Affected file configure.in.pre.
4678 * Added notion to protocol specification that server must
4679 verify the sent authentication payload with CMODE when
4680 setting the channel founder key. Implemented it to the
4681 server. Affected file silcd/command.c.
4683 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4685 * Added _EXTRA_DIST SILC distribution variable to the
4686 distributions file. It is used to conditionally add extra
4687 files or directories to the specific distribution. Affected
4688 files ./prepare, Makefile.am.pre and distributions.
4690 Removed the `_' from the start of the distribution names.
4693 * Added README.WIN32 for instructions to compile the Toolkit
4696 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4698 * Fixed a double free in disconnection in the server. Affected
4699 file is silcd/server.c.
4701 * Fixed the lib/silcske/groups.c to work now also with GMP
4702 MP library. The string conversion did not work when using
4703 specific base and the base is indicated in the string as well.
4705 * Created win32/ directory which now includes MSVC++ specific
4706 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4707 It will appear only in the toolkit distribution
4709 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4711 * Changed the key material distribution function in case when
4712 the hash output is too short. The data is now concatenated
4713 a bit differently than it used to. Made the change to the
4714 SKE protocol specification.
4716 * Added better GMP detection to configure.in.pre. A patch
4719 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4721 * Fixed a minor bug in SKE that might cause some problem on
4722 some platforms. Affected file lib/silcske/silcske.c.
4724 * Added the cookie checking for initiator in the SKE. It checks
4725 that the responder returns the sent cookie unmodified. The
4726 affected file is lib/silcske/silcske.c. Added new SKE
4727 error type INVALID_COOKIE that can be sent during the
4728 negotiation. Fixed some memory leaks as well.
4730 * Added the "invalid cookie" error message to Irssi SILC client's
4733 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4735 * Added `task_max' field to the SilcClientParams to indicate
4736 the maximum tasks the scheduler can handle. If set to zero,
4737 default values are used. Affected file lib/silcclient/silcapi.h.
4739 * Fixed memory leaks in silc_client_close_connection. Affected
4740 file lib/silcclient/client.c.
4742 * Added silc_client_del_client_entry to client library to free
4743 all memory of given client entry. Affected file is
4744 lib/silcclient/idlist.[ch].
4746 * Added new functions silc_client_del_channel and
4747 silc_client_del_server to delete channel and server entries.
4748 Affected file lib/silcclient/[silcapi.h/idlist.c].
4750 * Removed silc_client_del_client_by_id from silcapi.h.
4752 * Fixed the INFO command to return the server's own info
4753 correctly when querying by Server ID. Affected file is
4756 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4758 * Removed the non-blocking settings in WIN32 code in the
4759 silc_sock_[read/write] and added SleepEx instead. Affected
4760 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4761 of input data is now checked with FIONREAD and ioctlsocket.
4763 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4765 * Call silc_schedule_task_del_by_context in the
4766 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4767 Affected file lib/silccore/silcprotocol.c.
4769 * Call silc_protocol_cancel for active protocols in the
4770 silc_server_close_connection if the funtion
4771 silc_server_free_sock_user_data has not been called.
4772 Affected file silcd/server.c.
4774 * Generic tasks cannot be deleted using the del_by_fd
4775 task deleting function since generic tasks does not match
4776 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4778 * Added a notion to SILCOPER help file that the SILCOPER works
4779 only on router server, not on normal server.
4781 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4783 * Added for WIN32 support for the new scheduler as well.
4784 Affected file lib/silcutil/win32/silcwin32schedule.c.
4786 * Fixed the SHA1 implementation to work on various platforms.
4788 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4790 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4791 API. It is part of the scheduler now. Everything else is
4792 as previously but some functions has changed their names.
4793 Checkout the lib/silcutil/silcschedule.h for the interface.
4794 Updated all applications to use the new interface. Affected
4795 files are lib/silcutil/silcschedule.[ch].
4797 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4799 * Found a bug in the SKE implementation. The HASH value,
4800 specified by the protocol, was not computed correctly. The
4801 public key of the responder was not added to the computation
4802 even though it is mandatory. Affected file lib/silcske/silcske.c.
4803 This unfortunately causes incompatibilities with older
4804 clients and servers.
4806 * Added WIN32 specific network init and uninit functions:
4807 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4808 the Winsock2. Affected file lib/silcutil/silcnet.h and
4809 lib/silcutil/win32/silcwin32net.c.
4811 * Set the socket always to nonblocking mode on WIN32 after
4812 reading data or writing data. Affected file is
4813 lib/silcutil/win32/silcwin32sockconn.c.
4815 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4817 * Fixed various compilation problems under WIN32. Affected
4818 files lib/silcutil/win32/silcwin32thread.c and
4819 lib/silcutil/win32/silcwin32schedule.c.
4821 * Removed all _internal.h #includes from public header
4822 files. Internal headers must never be included from
4825 Removed also the lib/silcske/payload_internal.h file.
4827 * All include files that may be needed (public and some others
4828 included by the public headers) by application developers are
4829 now copied to the ./includes directory. It does not copy any
4830 internal headers. Affected file Makefile.defines.pre and all
4831 Makefile.am's under lib/ and subdirs.
4833 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4835 * Do not change the ~/.silc directory's permissions automatically.
4836 Affected file irssi/src/silc/core/clientutil.c.
4838 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4840 * Do not cancel the protocol in silc_server_close_connection
4841 it might cause recursion. Now cancelled in the function
4842 silc_server_free_sock_user_data. Affected file silcd/server.c.
4844 * Fixed the silc_server_remove_clients_by_server to regenerate
4845 the channel keys correctly finally. Added also new function
4846 silc_server_remove_clients_channels to actually do it.
4847 Affected file silcd/server.c.
4849 * Fixed the silc_server_new_channel to not crash by giving
4850 wrong router to the new channel. Affected file is
4851 silcd/packet_receive.c.
4853 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4855 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4856 which is given as argument to the silc_client_alloc now.
4857 It can be used to configure the client and set various parameters
4858 that affect the function of the client.
4860 * The USERS command in server did not check whether the channel
4861 is private or secret. Affected file silcd/command.c.
4863 * Added new argument to the USERS command in protocol specification.
4864 The USERS command now can take the channel name as argument
4865 as well. Added support for this in client and server and
4866 updated the protocol specs.
4868 * Completed the GETKEY command in client. It can be now used
4869 to fetch also servers public key not only some clients.
4870 Affected files lib/silcclient/command[_reply].c.
4872 * Added silc_client_get_server to return server entry by the
4873 server name. Affected files lib/silcclient/silcapi.h and
4876 * Redefined the IDENTIFY command in protocol specification to be
4877 more generic. It now can be used to query information about
4878 any entity in the SILC Network, including clients, servers and
4879 channels. The query may be based either the entity's name
4880 or the ID. Added support for this in both client and server.
4882 Affected files silcd/command.c and lib/silcclient/command.c
4883 and command_reply.c.
4885 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4886 the _from_client and _from_server functions. Affected file
4889 * Added silc_client_get_channel_by_id_resolve to the file
4890 lib/silcclient/silcapi.h to resolve channel information by
4891 its ID. Added also silc_client_get_channel_by_id that
4892 does not resolve it from the server.
4894 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4896 * Added SilcServerEntry context into the client library
4897 to represent one server. The INFO command now allocates
4898 these to save the resolved server info. For now on the
4899 client library will also keep information about servers,
4900 connected and resolved with INFO.
4902 The INFO command now allocates the SilcServerEntry context
4903 and saves the server info there. The COMMAND_REPLY in
4904 the INFO now returns the parameters to application in
4905 same order as defined in the protocol specification.
4907 The entries are cached in the client->server_cache.
4909 * The INFO command is now issued after received the Client ID
4910 from the server. Affected file lib/silcclient/client.c.
4912 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4913 to the application as the mode changer might be server.
4914 It is guaranteed that NULL is not returned anymore to the
4915 application. Affected file lib/silcclient/client_notify.c.
4917 The ID Type is now also passed to the application so that
4918 it can check whether the returned entry is SilcClientEntry
4921 Added new function silc_client_get_server_by_id to return
4922 the server entry by ID. Affected files are the
4923 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4925 * Do not create the channel in the Irssi SILC Client when issuing
4926 the JOIN command but when received the sucessful JOIN command
4927 reply. Otherwise the channel might get created even though we
4928 could not join it. The Affected file is
4929 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4931 * Fixed a channel joining bug in router. The router must also
4932 check the channel modes, invite and ban lists etc. when serving
4933 the JOIN command sent by normal server. Affected file is
4934 silcd/command.c. The router now resolves the client's
4935 information from the server who sent the JOIN command if it
4936 does not know it, and processes the JOIN command only after
4939 * Changed the SilcCommandCb to take new argument; void *context2.
4940 Affected file lib/silccore/silccommand.h
4942 The second argument in the command callbacks in the server now
4943 includes the SilcServerCommandReplyContext if the command was
4944 called as pending command callback from the command reply.
4945 Otherwise it is NULL. When called as pending the status of the
4946 command reply will be checked and if it was erronous the
4947 error will be sent to the original sender of the command.
4948 This way the client always receives the error messages even
4949 though the server was actually the one who received the error
4950 when it resent the command to router, for example. Affected
4951 files silcd/command[_reply].[ch].
4953 * Fixed sending WHOWAS command's error message to client if
4954 the requested client could not be found. It was missing.
4957 * Changed the CMODE and CUMODE commands reply arguments in the
4958 protocol specification. The Channel ID is now sent in both
4959 of the commands to identify the channel. Implemented this
4960 new feature to the client and server. Affected files
4961 lib/silcclient/command_reply.c and silcd/command.c.
4963 * Made better checks for invite and ban lists in the JOIN
4964 command in server. Affected file silcd/command.c.
4966 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4968 * The server now performs the incoming host IP/DNS lookup
4969 using the silc_socket_host_lookup and thus does not block
4970 the server anymore. Affected file silcd/server.c.
4972 * Completed the multi-thread support for SILC Scheduler in
4973 the lib/silcutil/silcschedule.c.
4975 * Fixed the configure.in.pre to detect the pthread correctly
4978 * Fixed a deadlock in silc_task_queue_wakeup in the file
4979 lib/silcutil/silctask.c.
4981 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4983 * Added new function silc_schedule_wakeup that is used in
4984 multi-threaded environment to wakeup the main thread's
4985 schduler. It needs to be used when a thread adds a new task
4986 or removes a task from task queues. After waking up, the
4987 scheduler will detect the task queue changes. If threads
4988 support is not compiled in this function has no effect.
4989 Implemented the wakeup mechanism to both Unix and WIN32
4990 systems. Affected files are lib/silcutil/silcschedule.[ch],
4991 lib/silcutil/unix/silcunixschedule.c and the
4992 lib/silcutil/win32/silcwin32schedule.c.
4994 * Added new function silc_task_queue_wakeup to wakeup the
4995 scheduler by the specified task queue. Affected file
4996 lib/silcutil/silctask.[ch].
4998 * The silc_socket_host_lookup_start now wakes up the scheduler
4999 after adding the timeout task. Affected file is
5000 lib/silcutil/silcsockconn.c.
5002 * The silc_socket_host_lookup is synchronous now if the threads
5003 support is not compiled in. However, the callback is still
5004 called asyncronously through the scheduler, anyway. Affected
5005 file lib/silcutil/silcsockconn.c.
5007 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5009 * Added new function silc_socket_host_lookup to perform
5010 asynchronous IP and FQDN lookups for the socket connection.
5011 Affected files lib/silcutil/silcsockconn.[ch].
5013 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5015 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5016 that may or may not compile the mutex support in.
5018 Changed the silc_mutex_alloc interface. It allocates the
5019 mutex now to the sent pointer and returns TRUE or FALSE.
5021 Affected file lib/silcutil/silcmutex.h.
5023 * Wrote the SILC Task Queue interface to support multi-threads.
5024 Affected file lib/silcutil/silctask.[ch].
5026 * Wrote the SILC Scheduler to support multi-threads. Affected
5027 file lib/silcutil/silcschedule.c.
5029 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5031 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5032 in lib/silcutil/win32/.
5034 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5036 * Defined SILC Mutex API and SILC Thread API and implemented
5037 them for Unix. Affected files are
5038 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5039 lib/silcutil/unix/silcunixmutex.c and
5040 lib/silcutil/unix/silcunixthread.c.
5042 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5044 * Fixed the silc_server_remove_clients_by_server's channel
5045 key re-generation. The hash table handling was incorrect
5046 and would not work with many channels. Affected file is
5049 * Fixed some memory leaks around the server code.
5051 * Rewrote the silc_server_get_users_on_channel to support IPv6
5052 based Client ID's. Affected file silcd/server.c.
5054 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5055 specification. However, a separate document must be written
5056 to define the detailed signing procedure and the payload
5057 associated with the flag. Defined the flag to the
5058 lib/silccore/silcchannel.h as well.
5060 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5062 * Changed the dynamic tables to static size tables in the
5063 lib/silccrypt/silchmac.c.
5065 * Removed GCC dependencies from the code. A patch by cras.
5067 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5069 * Do not show the error "Error receiving packet bla bla"
5070 in server if it really was not an error (-2 means that reading
5071 is pending). Affected file silcd/server.c.
5073 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5075 * Fixed a possible crash in silc_server_remove_clients_by_server
5076 in silcd/server.c. Fixed there also some memory leaks.
5078 * Fixed the silc_idlist_replace_client_id. It could replace
5079 wrong key in the hash table. Affected file silcd/idlist.c.
5081 * Do not check whether there are global users on the channel
5082 if the channel->global_users is FALSE. Affected functions
5083 silc_server_remove_from_one_channel and
5084 silc_server_remove_from_channels in silcd/server.c. Also,
5085 do not check if the removed client is local as we can be
5086 sure that global client was not removed from the channel
5087 and checking for global users is not needed.
5089 * The silc_server_remove_clients_by_server now re-generates
5090 the channel keys correctly for those channels that had
5091 clients removed from them. Affected file silcd/server.c.
5093 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5095 * Found the reason of random crashes in the server. We weren't
5096 ignoring the SIGPIPE signal (which can be sent in write())
5097 and it crashed the server. Affected file silcd/silcd.c.
5099 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5101 * Assure that sock->user_data is not NULL in the function
5102 silc_server_packet_send in silcd/packet_send.c.
5104 * Disconnect the remote connection if it could not be added
5105 to any ID lists in the server. The affected file is
5108 * Check in silc_server_packet_send[_real/dest] that the
5109 socket is not disconnecting and ignore the data if it is.
5110 Affected file silcd/packet_send.c.
5112 * Define inline to __inline on native WIN32 compilation.
5113 Affected file includes/silcwin32.h.
5115 * Added some explicit type casts for inline code since MSVC
5116 require them. Affected files lib/silcutil/silcbuffer.h,
5117 lib/trq/silcdlist.h and lib/trq/silclist.h.
5119 * Print warning in log files from now on if the packet
5120 decryption fails. Affected file silcd/server.c.
5122 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5124 * Changed the `say' client operation's interface to accept
5125 new `type' argument to indicate the type of the message sent
5126 by the library. The application may filter the library's
5127 messages according the type. The affected file is the
5128 lib/silcclient/silcapi.h.
5130 * Added two new functions to lib/silcclient/silcapi.h:
5131 silc_client_del_client and silc_client_del_client_by_id.
5132 Affected file lib/silcclient/idlist.c.
5134 * Moved the clientincludes.h from includes/ to silc/ and
5135 serverincludes.h from includes/ to silcd/.
5137 * The modes for the CMODE and CUMODE are now passed as
5138 uint32 for application with COMMAND_REPLY. The affected
5139 file is lib/silcclient/command_reply.c.
5141 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5143 * /WHOIS without arguments shows client's own information.
5144 Affected file lib/silcclient/command.c.
5146 * Changed PING to not accept any arguments. The specs
5147 says that client can ping only the connected server so
5148 requiring an argument is not needed. Affected file is
5149 lib/silcclient/command.c.
5151 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5153 * Fixed a fatal bug in private message sending and reception
5154 encryption and decryption when using private message keys.
5155 The implementation was incorrect and did not follow the
5156 specification. It causd that some of the message were
5157 lost since it did not use the sending and receiving keys
5158 as the protocol suggests. This has been fixed and will cause
5159 incompatibilities with older clients when sending private
5160 message encrypted with private message keys. Affected files
5161 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5162 and various other in Irssi SILC Client.
5164 Added `responder' boolean argument to the functions
5165 silc_client_add_private_message_key[_ske] to indicate when
5166 the key is added as responder or initiator of the key
5169 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5171 * Removed the silc_ske_check_version function and created
5172 a SilcSKECheckVersion callback. Added also a function
5173 silc_ske_set_callbacks that is now used to set all SKE
5174 callbacks. The callback functions are not given to
5175 the SKE functions anymore, but this function is used to
5178 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5180 * Added `silc_version' argument to the silc_client_alloc
5181 to define the version of the application for the library.
5182 The library will use the version string to compare it
5183 against the remote host's (usually a server) version
5184 string. Affected file lib/silcclient/silcapi.h
5186 * Added the KE protocol context to Key Agreement context
5187 in client library so that we can abort the SKE if it
5188 is in process when we get timeout. Affected file is
5189 lib/silcclient/client_keyagr.c.
5191 * Do not resolve the client ID forever if it returns in the
5192 first time that such client does not exist. This was done
5193 for example with private message. Affected file is
5194 lib/silcclient/client_prvmsg.c.
5196 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5198 * Do not add regex.h for WIN32. The affected file
5199 includes/silcincludes.h.
5201 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5202 not work yet 100%. It generates the DLL's automatically
5203 when compiling with --with-win32 under cygwin.
5205 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5207 * lib/contrib/regex.c is not compiled on WIN32.
5209 * Added silc_net_get_socket_opt function to the
5210 lib/silcutil/silcnet.h.
5212 * Added includes/silcwin32.h for WIN32 specific includes
5215 * Do not use ptime structure or any of the posix process
5216 functions on WIN32 in lib/silccrypt/silrng.c.
5218 * Added silc_gettimeofday to provide generic function
5219 for struct timeval on all platforms. Added the function
5220 to lib/silcutil/silcutil.h.
5222 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5224 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5225 library as they clearly belong there. As a plus side we
5226 can make the actual socket connection routines platform
5229 Added also new generic function silc_socket_read and
5230 silc_socket_write (that used to be silc_packet_[read/write].
5231 The implementation of these are platform specific.
5233 * Added WIN32 specific routines of silc_socket_[read/write]
5234 to lib/silcutil/win32/silcwin32sockconn.c.
5236 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5238 * Added preliminary support for native WIN32 compilation under
5239 cygwin (using the -mno-cygwin option for GCC) to the
5240 ./configure.in.pre. The --with-win32 now prepares the
5241 compilation for native WIN32.
5243 * Rewrote the SILC Scheduler interface in the file
5244 lib/silcutil/silcschedule.h. The scheduler is now context
5245 based and does not have anymore any global static scheduler.
5246 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5247 and created lib/silcutil/win32 directory for WIN32 based
5250 * Added Unix specific network routines to the
5251 lib/silcutil/unix/silcunixnet.c and the old
5252 lib/silcutil/silcnet.c includes now only generic routines.
5254 Added WIN32 specific network routines to the
5255 lib/silcutil/win32/silcwin32net.c.
5257 * Added Unix specific utility functions from the
5258 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5260 * Added WIN32 SILC Scheduler to the file
5261 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5264 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5266 * Do not handle JOIN notify in the server if the target client
5267 is not registered (idata->registered == FALSE). The affected
5268 file is silcd/packet_receive.c.
5270 * Update the nickrec->founder in event_cumode in the Irssi SILC
5271 client. Affected file irssi/src/silc/core/silc-channels.c.
5273 * Fixed the CUMODE_CHANGE notify handling in the server when
5274 server and router are announcing their clients on channels.
5275 Now the mode changes are saved and notified correctly. The
5276 affected file is /silcd/packet_receive.c.
5278 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5279 They really did not replace the cache entry in the ID Cache.
5280 Now they do that. Affected file silcd/idlist.c.
5282 * Fixed the KICK notify handling in the Irssi SILC client to
5283 update the channel records so that the kicked client does not
5284 appear to be on the channel. The affected file is
5285 irssi/src/silc/core/silc-channels.c.
5287 * Always update the conn->current_channel when executing command
5288 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5290 * Fixed the KILL notify handling in Irssi SILC client to remove
5291 the killed client on all channels.
5293 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5295 * Fixed the silc_parse_command_line to remove extra spaces
5296 from the start and end of the arguments. Affected file is
5297 lib/silcutil/silcutil.c.
5299 * Cancel and free any active protocol in the function
5300 silc_server_close_connection. Affected file silcd/server.c.
5302 * Cancel and free any active protocol in the function
5303 silc_client_close_connction. Affected file is
5304 lib/silcclient/client.c.
5306 * Do not execute the KILL command for clients that are in
5307 history (ie. they are not in the network). Affected file is
5310 * Fixed KILL notify handling, client does not crash anymore.
5311 Affected file irssi/src/silc/core/silc-channels.c.
5313 * Reduced the default packet buffer size from 2048 to 1024 in
5314 lib/silccore/silcpacket.c.
5316 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5317 counter to the SKE context that is incresed when the SKE library
5318 performs async operation outside the library. If the outside
5319 process frees the SKE context and FREED status will be set
5320 and the library will detect after the sync operation that the
5321 libary is freed. The affected files are
5322 lib/silcske/silcske[_status].[ch].
5324 * Resolve the client entry information in the function
5325 silc_client_channel_message to assure that NULL pointer is not
5326 passed as client entry to the application. */
5328 * Fixed the task timeout calculation to assure that there is
5329 never negative timeouts. The affected file is
5330 lib/silcutil/silcschedule.c.
5332 * Fixed the channel user mode notification sending in server.
5333 It was sent point-to-point to the router (or to server by router)
5334 but it needs to be destined to a channel. The routines now
5335 supports sending the channel user mode notifys to the channels
5336 when announcing clients and channels. Affected files are
5337 silcd/server.c and silcd/packet_receive.c.
5339 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5340 It did not actually replace the old channel entry in the cache.
5341 Affected file lib/silcclient/client_notify.c.
5343 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5345 * Fixed a possible crash in silc_packet_send_prepare. It now
5346 assures always that there is enough space in the buffer and
5347 at the tail area of the buffer (for MAC).
5349 Fixed the inbound buffer reallocation in silc_packet_read.
5350 It was old code and did not handle the reallocation correctly.
5353 The affected file is lib/silccore/silcpacket.c.
5355 * Fixed buffer overflow in silc_parse_nickname in the file
5356 lib/silcutil/silcutil.c.
5358 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * make install generates new server keys only if there is not
5363 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5366 Added check that if the NOREPLY is set then we will not send
5367 the away message. This avoids infinite loop of away messages
5368 if both clients are away. The affected file is
5369 lib/silcclient/client_prvmsg.c.
5371 * Fixed client crash if /NICK was given without arguments.
5372 Affected file lib/silcclient/command.c.
5374 * Server does not send the invite list in INVITE command back
5375 to the client if the list was not altered. Added this notion
5376 to the protocol spec as well. Affected file silcd/command.c.
5378 Fixed possible crash in INVITE command by checking the
5379 value of silc_server_get_client_route command.
5381 * Fixed the INVITE notify type handling. The arguments are now
5382 taken in correct order and client does not crash. The affected
5383 file is irssi/src/silc/core/silc-channels.c.
5385 Removed the "Inviting xxx to channel" message from the
5386 client library away and let the application handle it.
5387 Affected file lib/silcclient/command.c. Added that message
5388 to Irssi SILC client's message formats.
5390 * Fixed CMODE command crash in client. It now checks the
5391 amount of arguments correctly and does not crash. The affected
5392 file is lib/silcclient/command.c.
5394 * Do not create new channel automatically in silc_channels_join
5395 but check whether the channel by that name already exists.
5396 Affected file irssi/silc/core/silc-channels.c.
5398 * Do not send the SERVER_SIGNOFF to router if the disconnected
5399 entity was the router. Affected file silcd/server.c.
5401 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5402 SILC client as it was missing from there.
5404 Added the handling of the KICK notify to the Irssi SILC client
5405 as it was missing. Added "you have been kicked" message to
5406 Irssi SILC client's message modules formats.
5408 Added the handing of the KILL notify to the Irssi SILC client
5409 as it was missing. Added the kill message module formats
5412 The affected file is irssi/src/silc/core/silc-channels.c.
5414 * The router did not save the channel mode the server announced.
5415 Affected file silcd/packet_receive.c.
5417 * Fixed a possible crash in INFO command in server. If the
5418 server did not provide the server info it crashed. Affected
5419 file silcd/command.c.
5421 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Fixed the GETKEY command in the server to check also the
5424 global list. Otherwise the GETKEY would not work correctly
5425 in normal SILC server. Affected file silcd/command.c.
5427 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Fixed GETKEY crash, it crashed if the command did not succseed.
5431 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5433 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5434 is now real and not just an macro interface to GMP.
5436 Removed the entire GMP from the source tree and imported new
5437 NSS MPI library instead. Reason for removing GMP is that it is
5438 extremely large and compiles extremely slow. The NSS MPI
5439 is only a few files and compiles in less than 10 seconds.
5440 The speed is also about the same as GMP. The MPI is imported
5441 to lib/silcmath/mpi.
5443 If the system has GMP installed we will still use the GMP.
5444 If it is not then the NSS MPI will be compiled.
5446 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Merged a long nickname (127 characters long) crash bugfix from
5449 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5451 * Merged a freed memory reference bugfix from Irssi CVS tree.
5452 Affected file irssi/src/core/commands.c.
5454 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Added the server's public key sving and verification to the
5457 server when performing the SKE. This was missing and the
5458 remote server's (or router's) public key was accepted without
5459 checking whether we have it previously or trust it at all.
5460 Affected file silcd/protocol.c.
5462 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Check in the silc_server_timeout_remote if protocol is active
5465 and make sure that the protocol's final callback is called so
5466 that all memory if freed. Affected file silcd/server.c.
5468 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * silc_server_whois_send_reply crashed the server if the nickname
5471 was 127 characters long. Affected file silcd/command.c.
5473 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Added sanity check to the silc_server_new_client. If the hostname
5476 is provided inside username then check that the provided hostname
5477 really is the same as the resolved one. If the hostname was not
5478 resolved then check it from the public key. Affected file is
5479 silcd/packet_receive.c.
5481 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5482 if the server disconnected us and the connection is not valid
5483 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5485 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5486 the library to the lib/silcutil/silcutil.[ch].
5488 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5490 * Close log file after open. Affected file
5491 lib/silcutil/silclog.c.
5493 * Check whether sock == NULL in silc_client_send_packet and return
5494 if it is. Affected file lib/silcclient/silcclient.c.
5496 * Check rec->entry == NULL in the Irssi SILC Client before
5497 sending the channel message. Affecte file is
5498 irssi/src/silc/core/silc-servers.c.
5500 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5502 * Merged a splitted window bugfix from Irssi CVS tree. The
5503 affected file is irssi/src/fe-text/textbuffer-view.c.
5505 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5506 It did not print nickname.
5508 * Improved the distributions system a bit.
5510 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5513 irssi/src/fe-text/gui-window.c.
5515 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5516 to in-active server. The affected file is
5517 irssi/src/silc/core/client_ops.c.
5519 * Resolve the client in USERS command reply if the entry does
5520 not have username resolved. The affected file is
5521 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5522 command to WHOIS command to really resolve stuff. The USERS
5523 is not used any more in any critical section so WHOIS can
5524 be used even though it might be slower than IDENTIFY.
5526 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5529 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5531 * Changed the protocol API a bit more consistent in the
5532 lib/silccore/silcprotocol.[ch].
5534 * Changed the following headers to ROBODoc format:
5536 lib/silccore/silcpayload.h
5537 lib/silccore/silcprotocol.h
5538 lib/silccore/silcsockconn.h
5540 All core library headers are now formatted.
5542 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Fixed a bug in Irssi SILC client; do not show that you are
5545 server/router operator if you really are not. Affected file is
5546 irssi/src/silc/core/client_ops.c.
5548 * Renamed silc_command_free_payload to silc_command_payload_free.
5549 Affected file lib/silccore/silccommand.h
5551 * Added silcmath.h to include the prototoypes of various routines
5552 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5555 * Changed the following headers to ROBODoc format:
5557 lib/silccore/silcchannel.h
5558 lib/silccore/silccommand.h
5559 lib/silccore/silcid.h
5560 lib/silccore/silcidcache.h
5561 lib/silccore/silcmode.h
5562 lib/silccore/silcnotify.h
5563 lib/silccore/silcpacket.h
5564 lib/silcmath/silcmath.h
5566 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Added checking to the server code not to start the server if
5569 ciphers and stuff are not configured properly. Affected files
5570 silcd/serverconfig.[h] and silcd/server.c.
5572 * Changed the layout of the header files of the public interfaces
5573 in the SILC libraries. The new layout supports ROBODoc
5574 documentation tool (and some others) so that it is easy to create
5575 a library reference manual. All the other headers and source
5576 code must still follow the CodingStyle document. Also source
5577 code must not include these ROBODoc stuffs, only the headers.
5578 Furthermore, all public interface headers must now be named
5579 by using `silc' prefix, example: silcapi.h, silccipher.h.
5580 Some files were renamed due to this. All the other headers
5581 must not be used as public interfaces. I will update the
5582 CodingStyle document later. Changed following headers, so far:
5584 lib/silcclient/silcapi.h
5585 lib/silccore/silcauth.h
5586 lib/silccore/silcprivate.h
5587 lib/silccrypt/silcdh.h
5589 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Removed silc_client_packet_send_flush from the client library
5594 as it is not needed. Affected file lib/silcclient/client.[ch].
5596 * Added printing of message of unresolved authentication method
5597 to the Irssi SILC client. Added it to the module formats.
5598 Removed the same message from the client library.
5600 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added new distribution feature, DISTLABEL. Every distribution
5603 can define own preprocessor label that can be used in the
5604 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5605 file distributions, acconfig.h.pre and prepare.
5607 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Added Makefile.defines_int to include the actual definitions
5610 for Makefile.defines.in. Tested the new distribution system,
5611 created distributions and tested installation.
5613 * Added AWAY message printing to the Irssi SILC client. Added
5614 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5616 * Added SCONNECT command to call the SILC's CONNECT command.
5617 Cannot use CONNECT directly since Irssi uses that internally.
5618 Affected file irssi/src/silc/core/silc-servers.c.
5620 Added ACTION local command. It is same as ME command but takes
5621 the channel as mandatory argument.
5623 Rewrote some of the Irssi's help files to suite for SILC
5626 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Added Makefile.defines[.in] that should for now on be included
5629 in all Makefile.am file in the source tree. That file includes
5630 all common compilation definitions for SILC source tree.
5632 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Minor changes to the ./prepare script to change the package
5635 name according the distribution name to the configure.in.
5637 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Created new distribution system. Added file `distributions'
5640 that defines all the distributions that can be created out of
5641 the SILC source tree. The ./prepare script now reads that
5642 file to determine how to prepare the distributions. The
5643 first argument to the ./prepare is the name of the distribution
5644 and second is the version of the distribution. If given
5645 without arguments it creates the default (toolkit) distribution
5646 with the default version (defined in ./prepare).
5648 All Makefile.am files that are subject to the distributions
5649 are now named as Makefile.am.pre. These are ./Makefile.am
5650 and lib/Makefile.am. Others may be changed later.
5652 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Added invite list, ban list, some key management and connection
5655 error message printing to module formats in the Irssi SILC client.
5657 * Added new silc_client_set_away_message to set the away message
5658 that is back to the person who sent private message. The
5659 affected file lib/silcclient/silcapi.h and the
5660 lib/silcclient/client_prvmsg.c.
5662 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5664 * Fixed the private message sending in the Irssi SILC client,
5665 added local command KEY to the Irssi SILC client.
5667 Added key management and key agreement message formats to the
5668 irssi/src/fe-common/silc/module-formats.[ch].
5670 Added USERS (alias WHO) printing, server/router operator
5671 indication and LIST command printing to the module formats.
5673 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5675 * Fixed channel joining notify handling, cumode notify handling
5676 from Irssi SILC client.
5678 * Added SILC specific module-formats to the Irssi SILC client so
5679 that SILC specific message hilighting, colors etc is possible.
5680 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5682 Added channel mode, channel user mode, actions, notices,
5683 whois and whowas printing to the the module-formats.c.
5685 * Fixed a bug in channel deletion in the server. The channel
5686 is not left to the cache even if the channel founder auth mode
5687 is set when there are no users anymore on the channel. Affected
5688 file silcd/server.c.
5690 * The silc_net_localhost now resolves the entire hostname including
5691 the domain name. Affected file lib/silcutil/silcnet.c.
5693 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Changed the ask_passphrase client operation to be ascynchronous.
5696 It has now a completion callback and a context that the
5697 application must call after it has got the passphrase from
5698 the user. Affected files lib/silcclient/silcapi.h,
5699 lib/silcclient/protocol.c, lib/silcclient/command.c and
5702 Added SilcAskPassphrase callback that the application calls
5703 to deliver the passphrase to the library.
5705 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5706 The public key verification and especially a certificate
5707 verification is asynchronous procedure.
5709 Added new SILC_SKE_STATUS_PENDING status to indicate the
5710 request is pending and a callback will be called to finalize
5713 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5714 indicate that remote end did not send its public key (or
5715 certificate), even though we require it. Added check for this
5716 condition in the SKE. This was a security bug, now fixed.
5718 Defined new SilcSKEVerifyCbCompletion callback that is called
5719 when the verification process is completed.
5721 The affected files lib/silcske/silcske_status.h and
5722 lib/silcske/silcske.[ch].
5724 * Changed the verify_public_key client operation to be async
5725 as well. Defined SilcVerifyPublicKey callback that is used to
5726 indicate the success of the public key verification process.
5728 Changed the server and client to use the new async client
5731 * Changed the Irssi SILC client's internal scheduler to be called
5732 twice as many times as it used to be. As a result the client
5733 should be a bit faster now. Affected file is
5734 irssi/src/silc/core/silc-core.c.
5736 * Added support to Irssi SILC client of asynchronous public key
5737 verification and passphrase inquiry. Affected file is
5738 irssi/src/silc/core/silc-core.c.
5740 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Do not say "You have left channel %s" in client library.
5743 Moved it to the application. Affected files are
5744 lib/silcclient/command.c and silc/client_ops.c.
5746 * Fixed silc_client_get_clients. Command context was not
5747 duplicated and was freed memory in the callback. Affected
5748 file lib/silcclient/idlist.c.
5750 * Do not say "you are now talking..." on JOIN command in the
5751 client library. The appliation must handle it.
5753 * Do not say ".. changed topic to" in command reply in the
5754 client libary. The application must handle it.
5756 * Fixed TOPIC command sending in the client library.
5758 * Fixed a memory leak in silc_client_command_free in the file
5759 lib/silcclient/command.c.
5761 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Imported a modified version of Irssi client to the source tree.
5764 The Irssi will be used to create a new client called
5765 Irssi SILC. Imported to irssi/.
5767 Added silc_core_init_finish function to the Irssi. Affected
5768 file irssi/configure.in.
5770 A lot changes in the Makefile.ams around the irssi tree.
5772 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Do not rehash if the new size is same as the old size of the
5775 hash table, in the silc_hash_table_rehash*. The affected file
5776 lib/silcutil/silchashtable.c.
5778 * Replaced hash_table_del_by_context calls from the server
5779 (when channel->user_list and client->channels) to the
5780 hash_table_del as it is sufficient and faster.
5782 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Added silc_hash_table_list, silc_hash_table_get and the
5785 SilcHashTableList structure to provide an alternative way to
5786 traverse the hash table. The affected files are
5787 lib/silcutil/silchashtable.[ch].
5789 * Changed the server's idlist routines to use the hash table
5790 routines to optimize the code.
5792 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Replaced the client entry's `channel' list and channel entry's
5795 `user_list' list to hash tables for optimized lookup. Changed
5796 the code to use the hash table interface around the code.
5797 Affected file lib/silcd/idlist.[ch].
5799 * Added `auto_rehash' boolean argument to the function
5800 silc_hash_table_alloc to indicate whether the hash table should
5801 auto-rehash when it thinks is appropriate time. It will
5802 increase the hash table size if the there is twice as much
5803 entries in the table than the size of the table, and will
5804 decrease the size if there are twice as less entries than
5805 the size of the table.
5807 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5811 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5813 * silc_idcache_purge_by_context deletes the entry now by context
5814 as it is supposed to do. Affected file lib/silccore/idcache.c.
5816 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5817 client is not anymore valid (WHOWAS givens the info) and not
5818 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5820 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Removed the `data' and `data_len' arguments from the ID Cache
5823 interfaces and added `name' argument. ID Cache does not handle
5824 anymore the binary data only a names associated with given ID.
5826 * When hashing a Client ID with silc_hash_id the entire ID is
5827 not hashed anymore, instead only the hash of the Client ID is
5828 hashed. This way we can access the Client ID from the cache
5829 with Client ID but with the hash of the ID (which is a hash of
5830 the nickname) as well without any difference in performance.
5832 Added also silc_idcache_find_by_id_one_ext to do one on one
5833 searching when we have the actual ID. Added also function
5834 silc_hash_client_id_compare. The affected files are
5835 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5837 * When hashing the name associated with a ID it is always done
5838 in lowercase. This way we can access the cache without worrying
5839 about case-sensitivity, even though, for example nicknames are
5842 * Fixed a bug in server with channel message sending. It put
5843 wrong ID type as destination ID. The affected file
5844 silcd/packet_send.c.
5846 * silc_idcache_del_by_context now deletes from all hash tables
5847 by context. Affected file lib/silccore/idcache.c.
5849 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Changed the client library to use the new ID Cache interface.
5852 Changes around the source tree.
5854 * Added silc_hash_table_rehash_ext to rehash with specific
5855 hash function. Affected file lib/silcutil/silchashtable.[ch].
5857 * Added silc_hash_string_compare to compare two strings in the
5858 hash table. Affected file lib/silcutil/silcutil.[ch].
5860 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Added new function silc_idcache_del_by_context into the
5863 lib/silccore/idcache.[ch].
5865 * Changed the server's ID list routines to use the new ID Cache
5866 interface. Changes around the source tree.
5868 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added silc_hash_table_del[_by_context]_ext functions in to the
5871 lib/silcutil/silchashtable.[ch].
5873 Removed silc_hash_table_find_all* routines and added new
5874 silc_hash_table_find_foreach to replace them.
5876 Added silc_hash_table_replace_ext function as extended
5877 replacing function. Separated the simple hash table interface
5878 from the extended hash table interface in the file
5879 lib/silcutil/silchashtable.h.
5881 * Fixed minor bugs and changed it to use some of the new
5882 hash table functions in lib/silccore/idcache.c
5884 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5886 * Added new function silc_hash_table_find_all to return all keys
5887 in the hash table by the specified key. As the hash table is
5888 collision resistant it also makes it possible to have several
5889 duplicate keys in the hash table. This function may be used to
5890 find all of the keys from the hash.
5892 Added user_context arguments to the SilcHashFunction,
5893 SilcHashCompare and SilcHashDestructor to deliver user specified
5896 Added new fuctions silc_hash_table_find[_all]_ext to do
5897 extended lookup with specified hash and compare functions and
5898 specified user contexts.
5900 Added new function silc_hash_table_add_ext to add the key
5901 with specified hash function and user context.
5903 Added new function silc_hash_table_foreach to traverse all
5904 entrys in the hash table. Added SilcHashForeach callback
5907 Added new function silc_hash_table_del_by_context to delete
5908 the entry only if the context associated with the key matches.
5910 Affected files are lib/silcutil/silchashtable.[ch].
5912 * Removed silc_hash_[server/client/channel]_id and added just
5913 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5914 silc_hash_id_compare to compare two ID's using as the hash table
5915 comparison function. Added also silc_hash_data to hash
5916 binary data and silc_hash_data_compare to compare it.
5918 * Removed silc_idlist_find_client_by_hash as it is not needed
5919 anymore. Affected file silcd/idlist.[ch].
5921 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5922 to use internally the SilcHashTable. The new ID Cache is a lot
5923 faster than the old one. Some of the ID Cache interface was also
5924 rewritten and obsolete and stupid functions were removed.
5926 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5928 * Added entry_count field to the SilcHashTable to keep the number
5929 of the entries in the table. Implemented the function
5930 silc_hash_table_rehash. Added new function
5931 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5933 Fixed a minor bug in silc_hash_table_free.
5935 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5936 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5937 into the lib/silcutil/silcutil.[ch].
5939 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5941 * Implemented a collision resistant hash table into the
5942 lib/silcutil/silchashtable[ch]. See the header and the source
5943 for the SilcHashTable API.
5945 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5947 * Merged dotconf version 1.0.2 into lib/dotconf.
5949 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Do not compile anything in lib/silcsim/* if the SIM support
5952 is not enabled. The tree should now compile without problems
5955 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Compiled the SILC under cygwin. Compiled and tested briefly
5958 without problems. More tests needed. The SIMs didn't compile
5961 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5963 * Fixed possible crash in silc_get_username in the
5964 lib/silcutil/silcutil.c.
5966 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Fixed a va_arg in silc/client_ops.c.
5970 * Oops, RC5 routines were named AES and caused some problems
5971 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5973 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Added new SilcIDIP structure into the lib/silccore/id.h and
5976 replaced the old `ip' fields from all SILC ID's to that type.
5977 This is a step towards IPv6 support.
5979 The silc_id_get_len takes now the ID as an extra argument.
5980 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5981 both IPv4 and IPv6 based ID's.
5983 The affected files are lib/silccore/id.[ch] and other files
5984 around the tree using these routines.
5986 * Removed the ID length arguments in server from various
5987 silc_server_send_notify_* routines -> they are not needed
5990 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Fixed memory leak in silc_encode_pem_file in the file
5993 lib/silcutil/silcutil.c.
5995 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Check minor version as well in the SKE. Affected files are
5998 silcd/protocol.c and lib/silcclient/protocol.c.
6000 * Added --identifier option to the server so that an identifier
6001 can be when creating the public key for the server. Affected
6002 file is silcd/silcd.c.
6004 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
6005 lib/silccrypt/silcpkcs.c.
6007 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6009 * Register default ciphers and stuff when using -C option with
6010 the server. Affected file sildc/silcd.c.
6012 * Put back the servers public key filename format, it is better
6013 than the new one. For now, the client keys are saved with the
6014 new filename format. The affected file silc/client_ops.c.
6016 * Implemented the Cipher API for the rest of the ciphers that
6017 did not implement it or implemented it the wrong way.
6019 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Register default ciphers and stuff when using the -S option
6022 in the client. Affected file silc/silc.c. Same also when
6023 creating new key pair with -C option.
6025 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Fixed the silc_verify_public_key client operation function to
6028 save the public keys differently. The fingerprint is now
6029 used as filename and not the hostname. This way also the
6030 client keys are saved uniquely and not with hostnames. The
6031 affected file is silc/client_ops.c.
6033 * Trimmed the silc_hash_fingerprint function to remove extra
6034 whitespaces from the end of the fingerprint. The affected
6035 file is lib/silccrypt/silchash.c.
6039 * Added silc_cipher_register_default function to register all
6040 default ciphers. It can be used when configuration files
6041 does not exist and the application does not want any specific
6042 ciphers in any specific order.
6044 The SilcDList is now used as silc_cipher_list dynamically
6045 allocated cipher list. Removed the static list all together
6046 and now all ciphers must be allocated to the dynamic list.
6047 The silc_cipher_alloc routine was changed to check only the
6050 All silc_cipher_* routines that used to return int returns
6053 The affected files lib/silccrypt/silccrypt.[ch].
6055 * The same thing was done to silc_hash_* as for silc_cipher_*
6056 routines. Affected files lib/silccrypt/silchash.[ch].
6058 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6059 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6060 Added also silc_pkcs_[un]register[_default] functions.
6061 Removed the data_context from the PKCS API.
6063 * Added silc_hmac_register_default function to register default
6064 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6065 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6066 to unregister all hmacs at once.
6068 * Register the default ciphers, hash functions, PKCSs and HMACs
6069 if client's configuration file does not exist. The affected
6072 * The client did not load the hash functions from the SIM
6073 modules at all. Added support for this. Affected file is
6074 silc/clientconfig.c.
6076 * When decoding public key with silc_pkcs_public_key_decode, check
6077 the supported algorithm only if PKCS are registered. Affected
6078 file lib/silccrypt/silcpkcs.c. The same was done with the
6079 silc_pkcs_private_key_decode.
6081 * Fixed the SILC List routines to keep the list always in order.
6082 It used to change the list's order when traversing the list but
6083 not it preserves the order. Affected file lib/trq/silclist.h.
6085 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Added the client library to use the SilcSocketConnection's
6088 reference counter (by silc_socket_dup) to prevent the bug that
6089 the socket object may be freed underneath async operation.
6091 * The name resolv library checking fixes in the configure.in.pre.
6094 * Created new version of the protocol drafts for future
6095 development. The -03 drafts are the ones that will be changed
6096 in the trunk now and the -02 will remain as they are.
6098 * Send list of CUMODE notifys to the router when announcing
6099 the channel users to the router. Affected file silcd/server.c.
6100 If the router receiving channel founder CUMODE for a channel
6101 that already has channel founder it will send CUMODE notify
6102 to the sender to remove the channel founder rights from the
6103 announced client. Affected file silcd/packet_receive.c.
6105 * The CUMODE notify may now use Server ID as well as the entity
6106 who changes the mode. Updated protocool specs.
6108 * Updated INSTALL and README files.
6110 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * New web pages in the http://silc.pspt.fi. The pages was
6117 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Implemented the [DenyConnectin] config section in the server.
6120 Added silc_server_config_denied_conn to check whether incoming
6121 connection is denied. Affected file silcd/serverconfig.[ch].
6123 * Do not check the ports when checking the incoming configuration
6124 data if the port is 0, meaning any. Affected file is
6125 silcd/serverconfig.c.
6127 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Fixed buffer overflow in silc_string_compare in the file
6130 lib/silcutil/silcutil.c.
6132 * Fixed double free in silc_server_command_leave in the file
6135 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6137 * Fixed the version checking in the server. Affected file is
6140 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Fixed the configuration data fetching when accepting new
6143 connections in the server. Affected file silcd/server.c.
6145 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Added `sender_entry' argument to the function
6148 silc_server_packet_relay_to_channel so that we can check
6149 whether some destination actually belongs to the same route
6150 the sender belongs (ie, we must not resend the packet to the
6151 sender). Affected file silcd/packet_send.[ch].
6153 * Added `servername' field to the SilcClientEntry in the server
6154 to hold the name of the server where client is from. Affected
6155 file is silcd/idlist.h.
6157 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Moved the channel message encrypting in the router betwen
6160 router connections from silc_server_channel_message to the
6161 silc_server_packet_relay_to_channel since we want to check
6162 whether we have anybody channel before encrypting anything.
6163 Affected files silcd/packet_[receive/send].c.
6165 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Fixed the [AdminConnection] server config section to support
6168 multiple entries. Affected file silcd/serverconfig.c.
6170 * Added support into the server to check the validity of the
6171 incoming connection before executing any KE or authentication
6174 * The connection configuration is now saved to the KE and
6175 connection auth protocol contexts and not fetched anymore in
6176 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6178 * The local hosts listenning address and port is also resolved
6179 now when starting the server. We want to have the socket object
6180 to include the real address and port for the listener. Added
6181 new function silc_net_check_local_by_sock into the files
6182 lib/silcutil/silcnet.[ch].
6184 * Fixed a broadcast bug in server -> do not broadcast if we
6187 * Fixed a routing bug. Do not route broadcast packets ever.
6188 Broadcast packets must be processed always and not routed since
6189 they may be destined to some other host than yourself and thus
6190 would get routed without no good reason. Affected file is
6193 * Added function silc_server_config_is_primary_route to check
6194 whether primary router connection has been configured (a router
6195 configuration that we are initiating). If there is not, we
6196 will assume that there is only two routers in the SILC network
6197 and we will use the incoming router connection as our primary
6198 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6200 * Changed the order of the broadcasting. Broadcast _after_ the
6201 packet has been processed not before. Affected file is
6204 * Fixed a [ClientConnection] parsing bug. The port was never
6205 parsed correctly thus resulting to port 0. Affected file
6206 silcd/serverconfig.c.
6208 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6209 argument and did not set the broadcast packet flag. Affected
6210 file silcd/packet_send.c. Fixed same bug in the function
6211 silc_server_send_notify as well.
6213 * If we receive NEW_ID packet for our own ID in the server, ignore
6216 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6220 * Removed the nickname from the Private Message Payload.
6221 Updated the code and the protocol specs.
6223 * Updated protocol specs for submitting to the IETF.
6225 * Tweaked the Random Number Generator a bit. Affected file
6226 lib/silccrypt/silcrng.c. Exported a new function
6227 silc_rng_[global]_add_noise which can be used to add more
6230 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * Do not parse packets with different timeout when protocol
6233 is active -> may cause problem with rekey. Affected file
6236 * When server receives signoff notify it must not create
6237 new channel key if the client is on any channels since the
6238 sender of the signoff notify will create it.
6240 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Added printing of error messages during SKE protocol from the
6243 failure packet sent by server during SKE. Affected file
6246 * Removed the client's failure_callback handling with timeout
6247 and handle it immediately when received.
6249 * The SKE library returned wrong type in SUCCESS and FAILURE
6250 packets. They must be 32 bit MSB not 16 bit MSB.
6252 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Ok, rewrote the logic of the re-key and now it seems to work.
6255 I tested it on high traffic with frequent re-keys without
6256 problems. Added hmac_receive (and renamed hmac to hmac_send)
6257 in SilcClientConnection in lib/silcclient/client.h and
6258 in SilcIDListData in silcd/idlist.h. Also, removed the
6259 SilcPacketParserContext's cipher and hmac fields as they are
6260 not needed anymore and actually caused some problems when
6261 the ciphers and hmac's changed underneath the packet parser.
6263 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * If re-key protocol is active then process the incoming packets
6266 synchronously since we must assure that icoming packets encrypted
6267 with the old key is processed before the new keys is set to
6268 use. This is true other packets than for REKEY packets.
6269 Affected file silcd/server.c. The same was done to client library
6270 as well, affected file lib/silcclient/client.c.
6272 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Fixed bug in client and server to accept the force send if
6275 the packet is send from silc_[server/client]_packet_process
6276 function. Otherwise the packets are never delivered, oops.
6278 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6280 * Disable force sending of packets when REKEY protocol is active.
6281 We must assure that no packet is sent directly when rekey is
6282 performed. All packets must be sent through packet queue.
6283 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6284 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6285 function is silc_[server/client]_packet_send_real to check
6288 * Replaced the SIM paths from example config files to
6289 /usr/local/modules. Also, make install creates now
6290 /usr/local/silc/logs directory to hold all the SILC server
6293 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6304 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * When MAC computation fails the silc_packet_decrypt returned 0
6307 even though it was supposed to return -1. Fixed this. The
6308 affected file is lib/silccore/silcpacket.c.
6310 * Do not replace the config files in /etc/silc (in make install)
6311 if they already exist. Affected file ./Makefile.am.
6313 * Do not send re-key packets immediately but through packet queue.
6314 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6316 * Changed silc_net_check_host_by_sock to return FALSE if the
6317 IP/DNS could not be resolved. Though, it returns the IP address
6318 now even if it could not resolve it (but returns also FALSE).
6319 Affected file lib/silcutil/silcnet.[ch].
6321 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added silc_pkcs_decode_identifier to decode the public key's
6324 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6325 Added also silc_pkcs_free_identifier. Added also new context
6326 SilcPublicKeyIdentifier.
6328 * Added -S option to the silc client. It is used to dump the
6329 contents of the specified public key file.
6331 * Changed the PKCS api to return the public key length when
6332 setting the public key.
6334 * Fixed a fatal bug in the public and private key file loading.
6335 Affected file lib/silccrypt/silcpkcs.c.
6337 * Execute the packet parsing for client with zero (0) timeout
6338 if the protocol is active. Affected file silcd/server.c.
6340 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Made the key generation options to the silcd program. Added
6343 -C option, equivalent to client's option.
6345 * Added new [ServerKeys] config section to the server. It
6346 configures the server's public and private key.
6348 * Defined generic Public Key Payload into the protocol
6349 specification to send specific type of public keys and
6352 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6353 public key or certificate.
6355 * Implemented the GETKEY command to the server and to the
6356 client library and on user interface.
6358 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Made preliminary `make install' work.
6362 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6364 * Added SilcServerRekey context into silcd/idlist.h.
6366 * Added the PFS support as defined in the specification to the
6367 SKE protocol. Affected files lib/silcske/*.c.
6369 * Added `ske_group' field to the SilcServerRekey context to hold
6370 the number of the SKE group that is used with PFS in re-key.
6371 Affected file silcd/idlist.h.
6373 * Added PFS re-key support to the server. Affected file is
6376 * Added silc_protocol_cancel to cancel execution of the next
6377 state of the protocol. Affected file is
6378 lib/silccore/silcprotocol.[ch].
6380 * Added the re-key support with and without PFS to the client
6381 library. Re-key is performed once in an hour, by default.
6383 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6384 Added silc_client_rekey_callback and silc_client_rekey_final.
6385 Affected files are lib/silcclient/protocol.[ch] and
6386 lib/silcclient/client.[ch].
6388 * Removed the `hmac_key' and `hmac_key_len' fields from the
6389 SilcClientConnection structure; not needed. Affected file is
6390 lib/silcclient/client.h.
6394 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Do not ask whether user wants to use the negotiated private key
6397 for private messages, just use it. Affected file is
6398 silc/local_command.c.
6400 * Added `send_enc_key' and `enc_key_len' fields to the
6401 SilcIDListData structure since they are needed in the re-key
6402 phase. Affected file is silcd/idlist.[ch].
6404 * Implemented the simple re-key protocol into the server.
6405 Affected files silcd/server.c and silcd/protocol.[ch]. The
6406 re-key will be performed once in an hour, by default.
6408 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6409 Added silc_server_rekey, silc_server_rekey_callback and
6410 silc_server_rekey_final.
6412 * Removed Tunneled flag from the protocol. Updated the code
6413 and the specifications.
6415 * Adde `pfs' field to the SilcIDListData to indicate whether
6416 the PFS is to be performed in the re-key. Affected file is
6419 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6421 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6422 int64 of at least the xintXX size. If void * is less that 4
6423 bytes uint32 * will be used. Defined bool as boolean.
6425 * Changed _ALL_ unsigned long and unsigned int to uint32,
6426 unsgined short to uint16 in the source tree.
6428 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6429 not handle clients that has entry->data.registered == FALSE.
6430 They are not in the network anymore. Affected file is
6433 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Implemented the sending of the SERVER_SIGNOFF notify in the
6436 server. Affected file is silcd/server.c.
6438 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6439 Added also silc_notify_payload_encode_args into the
6440 lib/silccore/silcnotify.[ch].
6442 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6443 Affected file silcd/packet_receive.c.
6445 * Implemented the SERVER_SIGNOFF notify handling in the client
6446 library. Affected file lib/silcclient/client_notify.c. Also,
6447 implemnted the printing of the SERVER_SIGNOFF info to the
6448 application. Affected file silc/client_ops.c.
6450 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6451 if the deleting was successful. Affected file silcd/idlist.[ch].
6453 * Added support for public key authentication in the connection
6454 authentication protocol in the client library. Affected file
6455 lib/silcclient/protocol.c.
6457 * Changed the server's silc_idlist_get_clients_by_* interface
6458 to support already allocated array so that new entries may be
6459 added to pre-allocated array. Affected file silcd/idlist.[ch].
6460 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6461 and command replies.
6463 * All command reply functions in the server now calls the
6464 pending command callback even if error occured. This way the
6465 error will be delivered to the client as well. Affected files
6466 silcd/command.c and silcd/command_reply.c.
6468 * Fixed INFO command to return local server's info if no server
6469 was provided. Affected file lib/silcclient/command.c.
6471 * Removed RESTART command for good. Updated the code and the
6474 * Rewrote parts of the task system. It is a bit simpler now.
6475 Removed unsued task priorities. The affected files are
6476 lib/silcutil/silctask.[ch].
6478 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * Moved the USERS printing from the library to the application.
6481 Affected files lib/silcclient/command.c and silc/client_ops.c.
6483 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6487 * Added channel key re-key support. The re-key is perfomed
6488 only by the router and is done once in an hour. Added `rekey'
6489 field to the SilcChannelEntry in the server. Affected files
6490 silcd/server.c and silcd/idlist.h.
6492 * Added silc_task_unregister_by_context into the file
6493 lib/silcutil/silctask.[ch].
6495 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Added SILC_UMODE_GONE mode to indicate when the client is not
6498 present in the SILC network. Added also support to the local
6499 command AWAY that will set this mode. Added support of showing
6500 "xxx is gone" in WHOIS command. The USERS command shows the
6501 gone status as well.
6503 * Fixed setting server and router operator privileges in the
6504 server's UMODE command. Affected file silcd/command.c.
6506 * Merged the SKE KE1 and KE2 payloads into one payload. The
6507 new KE payload is equivalent to the old KE2 payload.
6509 Cleaned up the SKE Start Payload parsing. It now uses the
6510 simple buffer unformatting to do the parsing. A lot faster
6513 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6514 to the SKE that is used to indicate whether both of the SKE
6515 parties should perform authentication. By default only the
6516 responder performs authentication. By setting this flag also
6517 the initiator must do authentication. By default it is unset
6518 since in normal SKE case, client to server connection, only
6519 the responder should do authentication. When doing SKE between
6520 two clients both should perform authentication. Updated the
6521 code and the protocol specs.
6523 * A little fix to IDENTIFY command in the server. Search the
6524 client first by hash not nickname. Affected file is
6527 * Fixed the silc_client_close_connection to support closing
6528 the client to client connections wihtout deleting too much
6529 data. Affected file lib/silcclient/client.c.
6531 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6532 are received if protocol used to be active but is not anymore
6533 the application would crash due to NULL pointer dereference.
6534 Affected files silcd/server.c and lib/silcclient/client.c.
6536 * Added `hash' field to the SilcClientConnection to include
6537 the hash function negotiated in the SKE protocol.
6539 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6540 to set the channel founder authentication data. A client can
6541 claim the founder rights later by providing the authentication
6542 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6543 This way the channel founder can regain the channel founder
6544 privileges even it is left the channel. This works only on
6545 local server and the client must be connected to the same
6546 server to be able to regain the founder rights. Updated the
6547 protocol specs accordingly.
6549 Added support to the CMODE command in the client to set the
6550 founder auth data. Read the README to see how to set it.
6552 Added support to the CUMODE command to claim the founder
6553 rights. Read the README to see how to do it.
6555 Added support for the founder authentication to the Channel
6556 Entry in the server. Affected file silcd/idlist.h.
6558 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6559 server's CMODE command. Affected file silcd/command.c.
6561 * Added the following new functions into lib/silccore/silcauth.[ch]:
6562 silc_auth_get_method and silc_auth_get_data.
6564 * The server now saves the remote hosts public key to the
6565 SilcIDListData pointer. Affected file silcd/protocol.c.
6567 * The normal server now does not remove the channel entry from
6568 the cache if the founder authentication data is set. It used
6569 to remove it if the founder was the last one on the channel on
6570 the server and left the channel. The auth data is saved and
6571 if the channel is re-joined later the old entry is used with
6572 the old auth data. Affected files silcd/command_reply.c and
6575 * Removed the `pkcs' field from the SilcIDListData structure
6576 in the server; it is not used. Affected file silcd/idlist.h.
6578 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * Fixed packet processing on slow links. Partial packets were
6581 never re-processed because the incoming data buffer was cleared
6582 by the application. Application must not directly clear the
6583 sock->inbuf, the packet processing routines handle it. Fixed
6584 this in client library and in server.
6586 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6588 * Fixed the WHOIS and IDENTIFY send reply function to really
6589 check whether to send list or just one entry. Affected file
6592 * Cleaned up the LEAVE command's channel key distribution. The
6593 affected file silcd/command.c.
6595 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6596 can enforce the channel mode as well. In that case the ID
6597 includes the ID of the server. The code now enforces the
6598 mode change if the router have different mode than the server.
6600 * The notify client operation with CMODE_CHANGE notify can now
6601 return NULL client_entry pointer if the CMODE was not changed
6602 by client. Application must check for this.
6604 * Added <Server ID> argument to INFO command to support server
6605 info fetching by Server ID.
6607 * Added silc_server_announce_get_channel_users to get assembled
6608 packets of channel users of the specified channel. Affected
6609 file silcd/server.[ch].
6611 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6612 was freed underneath the ID Cache.
6614 * Re-announce clients when the server received CHANNEL_CHANGE
6615 notify from the router. Affected file silcd/packet_send.c.
6617 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6620 crashed since it did not handle the fact that there is no cipher
6621 called "3" and didn't check the error condition. Now fixed.
6623 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6624 flag. It can be used to send message requests.
6626 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Implemented the RESTART command in the client.
6630 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6631 notice type messages. Added notice printing to the user
6634 * The channel keys are not re-generated if the channel's mode
6635 is PRIVKEY, ie private key on the channel exists. Affected
6636 files silcd/server.c and silcd/command.c.
6638 * Fixed a little bug in channel message delivery when channel
6639 private keys are set in the server. Affected file is
6640 silcd/packet_send.c.
6642 * Changed the setting on channel->on_channel = TRUE from the
6643 silc_client_save_channel_key to the JOIN command reply. The
6644 key payload is not received if the private channel key is set.
6645 Affected file lib/silcclient/command_reply.c and the
6646 lib/silcclient/client_channel.c.
6648 * When the CMODE_CHANGE notify is sent and the channel private
6649 key mode is removed the channel key must be re-generated in
6650 other cells as well. Added this support for the router in the
6651 silcd/packet_receive.c.
6653 * Added new local command NOTICE to send notice message on
6654 channel. Affected file silc/local_command.[ch].
6656 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6658 * Added new local command ME to the client. It is used to send
6659 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6660 some action. Affected file silc/local_command.[ch].
6662 * Changed channel_message and private_message client operations
6663 to deliver the message flags to the application. Added also
6664 the `flags' arguments to the silc_client_send_channel_message
6665 and silc_client_send_private_message functions. Affected file
6668 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Redefined the Private Message Payload to support private message
6671 keys and to support the new private message flags. Updated
6672 the protocol specs. Flags makes it possible to have for example
6673 CTCP style messages.
6675 * Added new type SilcPrivateMessagePayload and defined an API
6676 for it in the lib/silcclient/silcprivate.[ch].
6678 * Tested private message private keys successfully. Tested the
6679 private message key set, unset and list commands with the new
6682 * Redefined the Channel Message Payload to include the channel
6683 message flags (equal with private message flags) to support
6684 for example CTCP style messages.
6686 * Defined some of the message (for channel and private message)
6687 flags. Updated the protocol specs and added the flags to the
6688 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6690 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Added SilcKeyAgreementStatus type to the key agreement routines
6693 to indicate the current status and error if one occured.
6694 The status types are defined in the lib/silcclient/silcapi.h.
6696 * Added new local command KEY that is used to set and unset private
6697 keys for channels, set and unset private keys for private messages
6698 with remote clients and to send key agreement requests and
6699 negotiate the key agreement protocol with remote client. The
6700 key agreement is supported only to negotiate private message keys,
6701 it currently cannot be used to negotiate private keys for channels,
6702 as it is not convenient for that purpose.
6704 * Fixed a minor pending callback setting bug in the function
6705 silc_client_get_client_by_id_resolve, now the function works.
6706 Affected file lib/silcclient/idlist.c.
6708 * Added function silc_net_get_local_port to get local bound
6709 port by socket. Added to lib/silcutil/silcnet.[ch].
6711 * Added `sockets' and `sockets_count' fields to the SilcClient
6712 object. They hold the sockets of the listenning sockets in
6713 the client. Listenning sockets may be for example the key
6714 agreement server. Affected file lib/silcclient/client.[ch].
6715 Added functions the silc_client_add_socket and the
6716 silc_client_del_socket. They are exported to the application
6719 * Added ~./silc/clientkeys to support other client's public keys.
6721 * Renamed verify_server_key client operation to verify_public_key
6722 and added one argument to indicate the type of the connection
6723 (server, client etc.).
6725 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6727 * Added silc_server_connection_auth_request to handle the
6728 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6729 silcd/packet_receive.[ch].
6731 * Added silc_server_send_connection_auth_request into the
6732 silcd/packet_send.c to send the connection auth request packet.
6734 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6737 * Fixed the public key authentication in responder side in the
6738 server. The `auth_data' pointer includes the SilcPublicKey
6739 not the path to the public key. Affected file silcd/protocol.c.
6741 * Implemented the public key authentication in the initiator side
6742 in the server. Affected file silcd/protocol.c.
6744 * Removed the [RedirectClient] config section from the server
6745 configuration. Is not needed and I don't want to implement it.
6747 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6749 * Cleaned up the CMODE command in the server. It now works
6750 correctly and supports all the modes defined in the protocol.
6751 Affected file is silcd/command.c.
6753 * Added `hmac_name' field to the SilcChannelEntry in the server
6754 to hold the default HMAC of the channel. It can be set when
6755 creating the channel (with JOIN command). Affected files
6758 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6759 type to indicate the change of the current cipher and hmac
6760 on the channel. Client can safely ignore the <cipher> argument
6761 (if it chooses to do so) since the CHANNEL_KEY packet will
6762 force the channel key change anyway. The <hmac> argument is
6763 important since the client is responsible of setting the new
6764 HMAC and the hmac key into use.
6766 * Fixed the CMODE command in the client library as well.
6768 * Tested CMODE command in router environment successfully.
6770 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Show the version of the remote client (or server) when connecting
6773 to the server. It is logged to the log file. Affected file
6774 is silcd/protocol.c.
6776 * Fixed the KILLED notify handling in the client library. The
6777 client must be removed from all channels when receiving the
6780 Also, do not remove the client entry when giving the KILL
6781 command but when the KILLED notify is received.
6783 * Removed silc_idlist_find_client_by_nickname from the server.
6784 Not needed anymore. Affected files silcd/idlist.[ch].
6786 * Implemented the CHANNEL_CHANGE notify type handling to the
6787 server. Affected file silcd/server.c.
6791 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * Added silc_server_send_notify_invite to send the INVITE
6794 notify between routers.
6796 * Implemented the INVITE command correctly to the server.
6798 * Implemented the INVITE notify type handling in the server.
6800 * Implemented the INVITE command to the client library and on the
6803 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Added function silc_server_get_client_resolve to find the
6806 client entry by ID from all ID lists and then resolve it
6807 (using WHOIS) if it cannot be found. Affected file is
6810 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Implemented the BAN command to the client library.
6814 * The JOIN command in the server now checks the invite list
6817 * Changed the silc_command_reply_payload_encode_va and the
6818 silc_command_payload_encode_va to support that if argument is
6819 NULL it ignores and checks the next argument. Affected file
6820 lib/silccore/silccommand.c.
6822 * Added silc_server_send_notify_ban to send the BAN notify
6823 type between routers.
6825 * Chaned the silc_notify_payload_encode to support that if
6826 argument is NULL it ignores and checks the next argument.
6827 Affected file lib/silccore/silcnotify.c.
6829 * Tested ban lists in router environment successfully.
6831 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Implemented BAN command to the server, in silcd/command.[ch].
6835 * Removed the BAN and INVITE_LIST modes from the CMODE command
6838 * Added function silc_string_match to regex match two strings.
6839 Affected files lib/silcutil/silcutil.[ch].
6841 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Redefined parts of the SilcChannelEntry in the server to support
6844 the new ban and invite lists.
6846 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Redefined the INVITE command. The same command can be used to
6849 invite individuals to the channel but also to manage the invite
6850 list of the channel (to add to and remove from the invite list).
6851 Updated the protocol specs.
6853 * Added new command SILC_COMMAND_BAN that can be used to manage
6854 the ban list of the channel. Updated the protocol specs.
6856 * Removed the channel modes: the SILC_CMODE_BAN and the
6857 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6858 in the CMODE command. The equivalent features are now available
6859 using INVITE and BAN commands. Updated the protocol specs.
6861 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6862 in the network about change in the current ban list. The notify
6863 type is not used by the client.
6865 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6866 support the invite lists.
6868 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6870 * Added new function silc_string_regexify that converts string
6871 including wildcard characters into regex string that can
6872 be used by the GNU regex library. Added into the file
6873 lib/silcutil/silcutil.[ch].
6875 Added silc_string_regex_combine to combine to regex strings
6876 into one so that they can be used as one regex string by
6877 the GNU regex library. Added into the file
6878 lib/silcutil/silcutil.[ch].
6880 Added silc_string_regex_match to match two strings. It returns
6881 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6883 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6885 * Imported GNU regex to the soruce tree into lib/contrib.
6886 Fixed some compiler warning from the regex.c.
6888 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Fixed MOTD command in the server to work in router environment.
6892 * Fixed the MOTD command in the client library to support
6893 the server argument in the command.
6895 * Added `nickname_len' argument to the silc_idlist_add_client
6896 in the server, as the `nickname' argument may be binary data
6899 * Added silc_idlist_get_channels to return all channels from
6902 * Implemented LIST command to the server. Affected file is
6905 * Implemented the LIST command to the client library and on the
6908 * Added [<user count>] argument to the LIST command reply.
6909 With private channels the user count is not shown.
6911 * Updated TODO and README.
6913 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6915 * The client entry's data.registered must be TRUE even with
6916 global client entry on global client list. The data.registered
6917 is used to check whether the client is anymore in the network,
6918 for example with WHOWAS command so it must be valid.
6920 * Fixed the WHOWAS command in the server. It now actually works
6921 in router environment. Added function into silcd/command_reply.c
6922 silc_server_command_reply_whowas_save.
6924 * Added silc_idlist_purge function to the silcd/idlist.c
6925 to periodically purge the ID Cache.
6927 * Fixed INFO command in the server. It works now in router
6928 environment. Added <server name> argument to the INFO command
6929 reply. Updated the protocol specs.
6931 * Fixed minor bug in silc_idcache_purge to not purge if the
6932 expire value is zero.
6934 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6935 they were buggy because of the WHOWAS information.
6937 * Fixed local command MSG to handle the async resolving of
6938 the remote client properly. It used to fail the first MSG.
6939 Affected file silc/local_command.c.
6941 * Added `data_len' field to SilcIDCache context.
6943 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Update TODO. Todo in commands in the server.
6947 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6949 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6950 used by routers as broadcast packet to inform other routers
6951 about the changed user mode.
6953 Implemented the notify handling in the server. Affected file is
6954 silcd/packet_receive.c. Added the function
6955 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6957 * Added new generic Channel Payload and deprecated the New Channel
6958 Payload. The New Channel Payload is now the generic Channel
6961 * Added new argument `mode' to the silc_server_send_new_channel
6962 as it is required in the Channel Payload now.
6964 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6965 and created a new and real SilChannelPayload to represent the
6966 new generic Channel Payload. Implemented the encode/decode
6967 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6969 * Added silc_server_get_client_channel_list to return the list
6970 of channels the client has joined for WHOIS command reply.
6971 Affected file silcd/server.[ch].
6973 * Implemented the channel list sending in the WHOIS command reply
6974 in server and in the client.
6976 Implemented the channel list displaying on the user interface
6977 as well. Affected file silc/client_ops.c.
6979 * Added silc_channel_payload_parse_list to parse list of Channel
6980 Payloads. It returns SilcDList list of SilcChannelPayloads.
6981 Client for example can use this function to parse the list of
6982 channels it receives in the WHOIS command reply. The caller
6983 must free the list by calling silc_channel_payload_list_free.
6984 Affected files lib/silccore/silcchannel.[ch].
6986 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Added one new argument <user mode> to the WHOIS command reply
6989 to return the mode of the user in SILC. Updated the protocol
6992 Implemented it to the server and client.
6994 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6996 * Fixed the mode printing on the user interface on joining.
6997 Affected file silc/client_ops.c.
6999 * Implemented the UMODE command and user modes in general to the
7000 client library and to the user interface.
7002 * Implemented the UMODE command to the server.
7004 * The server now sends UNKNOWN_COMMAND error status if client sends
7005 unknown command. Affected file silcd/command.c.
7007 * All server commands now handle the command identifier the right
7008 way when sending the command reply to the client. The client can
7009 use to identify the command replies with the identifier.
7011 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Added silc_server_get_client_route to resolve the route to
7014 the client indicated by the client ID. Affected file is
7017 * Added silc_server_relay_packet as general function to relay
7018 packet to arbitrary destination. This deprecates functions
7019 like _send_private_message_key, _relay_notify etc. Affected
7020 file is silcd/packet_send.[ch].
7022 Removed silc_server_send_key_agreement,
7023 silc_server_send_private_message_key and
7024 silc_server_packet_relay_notify functions from the file
7025 silcd/packet_send.[ch].
7029 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7030 server. Affected file silcd/packet_receive.[ch].
7032 * Implemented the KILL command to the client. Implemented the
7033 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7034 Affected files lib/silcclient/command[_reply].c and
7035 lib/silcclient/client_notify.c. Implemented the KILL notify
7036 printing in the user inteface.
7038 * Fixed a lot silc_parse_nick memory leaks from the client
7039 library in the file lib/silcclient/command.c.
7041 * Changed the silc_server_send_notify_on_channels's `sender'
7042 argument from SilcSocketConnection to SilcClientEntry to
7043 check the sender as entry and not as connection object and not
7044 to send to the client provided as argument. The affected file
7045 is silcd/packet_send.[ch].
7047 * The notify packets that are destined directly to the client used
7048 to not to be processed by the server. Now changed that and the
7049 server processes all notify packets. After relaying the packet
7050 to the client the notify packet is processed in the server.
7052 * The silc_server_free_client_data now checks whether there is
7053 pending outgoing traffic for the client and purges the data to
7054 the network before removing the client entry.
7056 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7059 an client is killed from the SILC Network. Updated the protocol
7062 Added new function silc_server_send_notify_killed to the
7063 silcd/packet_send.[ch].
7065 * Added function silc_server_packet_relay_notify to relay notify
7066 packets that are destined directly to a client. In this case
7067 the server does not process the notify packets but merely relays
7068 it to the client. Affected file silcd/packet_send.[ch].
7070 Added also silc_server_packet_process_relay_notify to check
7071 whereto relay the notify. Affected file is
7072 silcd/packet_receive.[ch].
7074 * Implemented the KILL command to the server.
7078 * Added the backup schema desgined last fall to the protocol
7079 specs for everyone to see. The specification is in the
7080 *-spec-xx.txt draft and the packet type definitions for the
7081 backup routers is in *-pp-xx.txt draft. Thusly, added also
7082 new packet type SILC_PACKET_CELL_ROUTERS.
7084 * A big security problem in the implementation discovered. The
7085 signoff of an client did not cause new channel key generation
7086 which it of course should've done. The channel keys must be
7087 always re-generated when client leaves (or signoffs) the channel.
7088 The silc_server_remove_from_channels funtion now handles
7089 the channel key re-generation.
7091 * Added `sender' argument to the silc_server_send_notify_on_channels
7092 to not to send the client provided as argument. Affected file
7093 silcd/packet_send.[ch].
7095 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7097 * Implemented OPER and SILCOPER commands into the server and
7100 * Added silc_auth_verify and silc_auth_verify_data to verify
7101 the authentication directly from the authentication payload.
7102 It supports verifying both passphrase and public key based
7103 authentication. Affected file lib/silccore/silcauth.[ch].
7105 * Added `hash' field to the SilcIDListData structure. It is the
7106 hash negotiated in the SKE protocol. Affected file is
7109 * Slight redesigning of the SilcAuthPayload handling routines.
7110 Do not send SilcPKCS but SilcPublicKey as argument.
7112 * Implemented the public key authentication support to the
7113 serverconfig. The public key is loaded from the provided path
7114 and saved as authentication data to void * pointer. Thus,
7115 changed the unsigned char *auth_data to void *auth_data;
7117 * Fixed SHUTDOWN command to send the reply before the server
7118 is shutdown. :) Affected file silcd/command.c.
7120 * Fixed fatal bug in CONNECT command. The hostname was invalid
7121 memory and server crashed. Affected file silcd/command.c.
7123 * Fixed fatal bug in CLOSE command. The server_entry became
7124 invalid but was referenced later in the command. Affected file
7127 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Fixed fatal bug in failure packet handling. Server ignored
7130 the failure and thus crashed when it came.
7134 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7137 that the command may be executed only once in (about) 2 seconds.
7138 The old SILC_CF_LAG flag is same but allows command bursts up
7139 to five before limiting.
7141 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7142 server code. Various commands now includes the CF_LAG_STRICT
7143 flag to disallow any kind of miss-use of the command.
7145 * Fixed the silc_buffer_unformat to not to allocate any data
7146 if the length of the data is zero. It used to allocate the
7147 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7149 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7151 * Changed the format of AdminConnection configuration section
7152 in the server. Added username of the admin to the format.
7153 Affected files silcd/serverconfig.[ch].
7155 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7156 to return admin configuration data by host, username and/or
7159 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Implemented WHOWAS command to the server. Added the functions:
7163 silc_server_command_whowas_parse,
7164 silc_server_command_whowas_send_reply,
7165 silc_server_command_whowas_from_client and
7166 silc_server_command_whowas_from_server
7168 * Added <Client ID> argument to the WHOWAS command reply. Updated
7169 the protocol specs accordingly.
7171 * Implemented WHOWAS command and command_reply to the client
7174 Implemented the WHOWAS printing on the user interface.
7176 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added new argument to the WHOWAS command reply, the real name.
7179 It is an optional argument. Updated the protocol specs.
7181 * Added SilcIDCacheDestructor callback that is registered when
7182 the SilcIDCache is allocated. The callback is called when
7183 an cache entry in the ID Cache expires, or is purged from the
7184 cache. Added into lib/silccore/idcache.[ch].
7186 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7187 to destruct the client entries when the cache entry expires.
7188 Other ID Cache's in server and in the client library ignores
7191 * If the ID Cache entry's `expire' field is zero then the entry
7192 never expires. Added boolean `expire' argument to the
7193 silc_idcache_add function in the lib/silccore/idcache.[ch].
7194 If it is TRUE the default expiry value is used.
7196 * Added silc_server_free_client_data_timeout that is registered
7197 when client disconnects. By default for 5 minutes we preserve
7198 the client entry for history - for WHOWAS command.
7200 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Added support to the server to enforce that commands are not
7203 executed more than once in 2 seconds. If server receives
7204 commands from client more frequently, timeout is registered
7205 to process the commands. Affected file silcd/command.c.
7206 Added new function silc_server_command_process_timeout.
7208 * Changed NICK_NOTIFY handling in client library to check that
7209 if the client's nickname was changed, so there is no need to
7210 resolve anything from the server.
7212 * Removed error printing from the WHOIS and IDENTIFY commands.
7213 If error occurs then it is ignored silently in the client library.
7214 The application, however, may map the received error to
7215 human readable error string. The application currently maps
7216 the NO_SUCH_NICKNAME error to string.
7218 * Made the command status message public to the application. Moved
7219 them from lib/silcclient/command_reply.c to
7220 lib/silcclient/command_reply.h. The application can map the
7221 received command status to the string with the
7222 silc_client_command_status_message function.
7224 * Added check to the server to check that client's ID is same
7225 as the Source ID in the packet the client sent. They must
7228 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Added dist-bzip hook to the Makefile.am to make bzip2
7231 compressed distributions.
7233 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Server now enforces the maximum length for the nickname and
7236 the channel as protocol specification dictates. 128 bytes for
7237 nickname and 256 bytes for channel name.
7239 * Moved the WHOIS printing to the application. The client libary
7240 does not print out the WHOIS information anymore, the application
7241 must do it. Renamed silc_client_command_reply_whois_print to
7242 the silc_client_command_reply_whois_save.
7244 The client's idle time is also sent to the application now, and
7245 the idle is shown on screen.
7247 * Added silc_client_command_reply_identify_save to save the
7248 received IDENTIFY entries.
7250 * Do not check for channel private keys in message sending and
7251 reception if the channel does not have the PRIVKEY mode set.
7252 Affected file lib/silclient/client_channel.c.
7254 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7256 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7257 just surfaced after chaning the JOIN procedure.
7259 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added silc_client_get_clients_by_list to get client entries
7262 from Client ID list, that is returned for example by JOIN
7263 and USERS command replies. The application should use this
7264 function for example when JOIN command reply is received to
7265 resolve the clients already on the channel (library does not
7266 do that anymore as USERS command reply is not used in the JOIN
7267 procedure anymore). Affected files lib/silcclient/silcapi.h and
7268 lib/silcclient/idlist.c.
7270 * JOIN command reply and USERS command reply returns now SilcBuffer
7271 pointers instead of unsigned char pointers when returning
7272 the client list and mode list.
7274 * Added <Client ID> argument to the JOIN command reply, mainly
7275 for the server to identify for which client the command was
7276 originally sent. Updated protocol specs accordingly.
7278 * Added SilcDlist private_key pointer to the SilcChannelEntry
7279 in the client to support the channel private keys. Affected
7280 file is lib/silcclient/idlist.h.
7282 * Added SilcChannelPrivateKey argument to the function
7283 silc_client_send_channel_message so that application can choose
7284 to use specific private ke if it wants to. If it is not provided,
7285 the normal channel key is used, unless private keys are set.
7286 In this case the first (key that was added first) is used
7287 as the encryption key.
7289 * Implemented the support for channel private key handling.
7290 Implemented the following functions:
7292 silc_client_add_channel_private_key,
7293 silc_client_del_channel_private_keys,
7294 silc_client_del_channel_private_key,
7295 silc_client_list_channel_private_keys and
7296 silc_client_free_channel_private_keys
7298 Affected file lib/silcclient/client_channel.c.
7300 * Added the support for the private keys in the channel message
7301 sending and encryption and in the message reception and
7302 decryption. Affected funtions are
7303 silc_client_send_channel_message and silc_client_channel_message.
7305 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7307 * Added SKE's key verify callback to the client library's
7308 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7310 * Removed the statement that server (or router) must send USERS
7311 command reply when joining to the channel so that the client
7312 knows who are on the channel. Instead, the client list and
7313 client's mode list is now sent in the JOIN command reply to the
7314 client who joined channel. This is better solution.
7316 * Added function silc_server_get_users_on_channel and function
7317 silc_server_save_users_on_channel to the silcd/server.[ch].
7319 * Removed function silc_server_command_send_users from the
7322 * Do not show topic on the client library anymore. The topic is
7323 sent in the command reply notify to the application and the
7324 application must show the topic now.
7326 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Added client searching by nickname hash into the IDENTIFY and
7329 WHOIS commands in the server as they were clearly missing from
7330 them. Affected file is silcd/command.c.
7332 * Fixed a bug in private message receiving in the client library.
7333 The remote ID was freed and it wasn't supposed, now it is
7336 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7338 * Minor fix to the channel payload; allocate the data area, as it
7339 needs to be of specific length.
7341 * If the key agreement port is zero then the operating
7342 system will define the bound port. Affected files are
7343 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7345 * Added new function silc_channel_payload_decrypt into the file
7346 lib/silccore/silcchannel.[ch].
7348 * Moved the channel message etc, check from silc_packet_decrypt
7349 to applications. The library calls now a generic
7350 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7351 when the packet is either normal or special. This was done to
7352 allow more wide range of checking that was not allowed when
7353 the code was in library. Now applications can do virtually any
7354 checks to the packet and return to the library the decision how
7355 the packet should be processed. Affected files are
7356 lib/silccore/silcpacket.[ch].
7358 Added silc_server_packet_decrypt_check to the server and
7359 silc_client_packet_decrypt_check to the client library.
7361 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7362 to send with specified source and destination information.
7364 * Channel message delivery between routers was broken after the
7365 channel key distribution was fixed earlier. The channel key
7366 was used be to distributed to other routers as well which is not
7367 allowed by the protocol. Now this is fixed and channel keys
7368 really are cell specific and the channel message delivery between
7369 routers comply with the protocol specification.
7371 * Fixed various commands in server to check also the global list
7372 for the channel entry and not just the local list. The affected
7373 file silcd/command.c.
7375 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Added assert()s to buffer formatting and unformatting routines
7378 to assert (if --enable-debug) when error occurs. Affected
7379 file: lib/silcutil/silcbuffmt.c.
7381 * Changed to auto-reconnect to check whether the remote host is
7382 router and register the re-connect timeout if it is. It used
7383 to check that whether we are normal server, but router must do
7384 auto-reconnect with another router as well. Affected file
7387 * Removed the [<key len>] option from CMODE command as the cipher
7388 name decides the key length, nowadays. See the defined ciphers
7389 from the protocol specification.
7391 * Added [<hmac>] option to the CMODE command to define the HMAC
7392 for the channel. Added SILC_CMODE_HMAC channel mode.
7394 * Added [<hmac>] option for the JOIN command so that user can
7395 select which HMAC is used to compute the MACs of the channel
7398 * Added Hmac field to the Channel Message Payload. The integrity
7399 of plaintext channel messages are now protected by computing
7400 MAC of the message and attaching the MAC to the payload. The
7401 MAC is encrypted. Now, it is clear that this causes some
7402 overhead to the size of the packet but rationale for this is that
7403 now the receiver can verify whether the channel message decrypted
7404 correctly and also when private keys are set for the channel the
7405 receiver can decrypt the packet with several keys and check from
7406 the MAC which key decrypted the message correctly.
7408 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7409 lib/silccrypt/silccipher.[ch].
7411 * Added silc_hash_len to return the digest length into the
7412 lib/silcrypt/silchash.[ch].
7414 * Rewrote parts of Silc Channel Payload interface in the
7415 lib/silccore/silcchannel.[ch]. The encode function now also
7416 encrypts the packet and parse function decrypts it.
7418 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Fixed a minor formatting bug in the SKE's key material processing.
7421 It actually might have processed the keys wrong way resulting
7424 * Redefined the mandatory HMAC algorithms and added new algorithms.
7425 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7426 and hmac-md5 truncated to 96 bits. The mandatory is now
7427 hmac-sha1-96. Rest are optional (including the one that used
7428 to be mandatory). Rationale for this is that the truncated HMAC
7429 length is sufficient from security point of view and can actually
7430 make the attack against the HMAC harder. Also, the truncated
7431 HMAC causes less overhead to the packets. See the RFC2104 for
7434 * Added new [hmac] configuration section. The SKE used to use
7435 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7436 is of course wrong. The official names that must be proposed in
7437 the SKE are the ones defined in the protocol specification
7438 (hmac-sha1-96 for example). The user can configure any hmac
7439 using any hash function configured in the [hash] section. At
7440 least, the mandatory must be configured.
7442 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7444 * Added HMAC list to the SKE proposal list. It has now both
7445 hash algorithm list and HMAC list. This makes the protocol
7446 incompatible with previous versions. The SKE now seems to work
7447 the way it is supposed to work, for the first time actually.
7449 * Defined plain Hash algorithms to the protocol specification.
7452 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Implemented support for key agreement packets into the server.
7455 Added functions silc_server_key_agreement and
7456 silc_server_send_key_agreement. Other than these functions,
7457 server has nothing to do with this packet.
7459 * Added support for private message key packets into the server.
7460 Added functions silc_server_private_message_key and
7461 silc_server_send_private_message_key.
7465 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7466 called in the protocol's final callback instead in the END
7467 protocol state. This makes a little more sense and in the same
7468 time in client we can use the same protocol routines for normal
7469 key exchange and to key agreement packet handling as well.
7471 * Added to both client's and server's KE protocol context the
7472 SilcSKEKeyMaterial pointer to save the key material. We will
7473 bring the key material to the protocol's final callback by doing
7474 this. The final callback must free the key material.
7476 * Added SKE's packet_send callback into client's KE protocol
7477 context so that the caller can choose what packet sending function
7478 is used. This way we can use different packet sending when
7479 doing normal SKE when doing key agreement packet handling (in
7480 the key agreement packet handling we do not want to encrypt
7483 * Implemented the responder side of the key agreement routines
7484 in the client. The client can now bind to specified port and
7485 accept incoming key negotiation. The key material is passed
7486 to the application after the protocol is over.
7488 * Implemented the processing of incoming Key Agreement packet
7489 in the client. Added function silc_client_key_agreement to
7492 * Implemented the intiator side of the key agreement routines
7493 in the client. The client can now initiate key agreement with
7494 another remote client. The key material is passed to the
7495 application after the protocol is over.
7497 * Created client_keyagr.c to include all the key agreement
7500 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7501 SILC_TASK_CALLBACK except that it is not static.
7503 * Created client_notify.c and moved the Notify packet handling
7504 from the client.[ch] into that file.
7506 * Created client_prvmsg.c and moved all private message and
7507 private message key routines from the client.[ch] into that file.
7509 * Create client_channel.c and moved all channel message and
7510 channel private key routines from the client.[ch] into that file.
7512 * Changed silc_client_get_client_by_id_resolve to resolve with
7513 WHOIS command instead of IDENTIFY command, in the file
7514 lib/silclient/idlist.c.
7516 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Implemented the SKE's responder side to the Client library.
7520 * When FAILURE is received to the protocol do not trust it
7521 blindly. Register a timeout to wait whether the remote closes
7522 the connection as it should do it, only after that process the
7523 actual failure. This was changed to both client and server.
7525 * Added client_internal.h to include some of the structures
7526 there instead of client.h in lib/silcclient/.
7528 * Added function silc_task_unregister_by_callback to unregister
7529 timeouts by the callback function.
7531 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7533 * Some "Incomplete WHOIS info" errors has been appearing on the
7534 log files. Took away the entry->userinfo check from WHOIS
7535 reply sending. The entry->userinfo is now " " if client did not
7536 provide one. I thought this was fixed earlier but something
7537 is wrong still. Let's see if the error still appears.
7539 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Fixed a minor bug in the login when the channel key is
7542 re-generated in the server. It used to generate the key in
7543 wrong order and thus caused problems in the channel traffic.
7545 * Fixed a minor bug in channel key distsribution after
7546 KICK command. The key was not sent to the router even though
7549 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Added silc_ske_process_key_material_data as generic routine
7552 to process any key material as the SILC protocol dictates. The
7553 function is used by the actual SKE library but can be used by
7554 applications as well. This relates to the private message keys
7555 and the channel private keys since they must be processed the
7556 same way the normal SILC session keys. The protocol dictates
7557 this. Affected files: lib/silcske/silcske.[ch].
7559 Added also silc_ske_free_key_material to free the
7560 SilcSKEKeyMaterial structure.
7562 * Defined silc_cipher_set_key function to set the key for
7563 cipher without using the object's method function. The affected
7564 files: lib/silccrypt/silccipher.[ch].
7566 * Implemented silc silc_client_add_private_message_key,
7567 silc_client_add_private_message_key_ske,
7568 silc_client_del_private_message_key,
7569 silc_client_list_private_message_keys and
7570 silc_client_free_private_message_keys functions in the
7573 Added functions silc_client_send_private_message_key to send
7574 the Private Message Key payload and silc_client_private_message_key
7575 to handle incoming Private Message Key payload.
7577 * Added Cipher field to the Private Message Key payload to set
7578 the cipher to be used. If ignored, the default cipher defined
7579 in the SILC protocol (aes-256-cbc) is used.
7581 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7583 * Removed lib/silcclient/ops.h file.
7585 Redefined parts of the SILC Client Library API. Created new
7586 file silcapi.h that deprecates the ops.h file and defines the
7587 published Client Library API. Defined also private message key
7588 API and channel private key API into the file.
7590 This is the file that the application must include from the
7591 SILC Client Library. Other files need not be included by
7592 the application anymore.
7594 * Added new key_agreement client operation callback and also
7595 defined the Key Agreement library API for the application.
7597 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7599 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7600 is used by clients to request key negotiation between another
7601 client in the SILC network. If the negotiation is started it
7602 is performed using the SKE protocol. The result of the
7603 negotiation, the secret key material, can be used for example
7604 as private message key.
7606 Implemented the Key Agreement payload into the files
7607 lib/silccore/silauth.[ch].
7609 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7611 * Redefined ciphers for the SILC protocol. Added some new ciphers
7612 and defined the key lengths for the algorithms. Changed the
7613 code accordingly. The default key length is now 256 bits.
7615 * Fixed SKE key distribution function silc_ske_process_key_material
7616 when the key length is more than 128 bits. The default key
7617 length in SILC is now 256 bits.
7619 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7620 to indicate unsupported algorithm.
7622 * Renamed rijndael.c to aes.c and all functions as well.
7624 * Fixed a long standing channel key setting bug in client library.
7625 Weird that it has never surfaced before.
7627 * Fixed bug in channel deletion. If the entire channel is removed
7628 then it must also delete the references of the channel entry
7629 from the client's channel list as the client's channel entry and
7630 the channel's client entry share same memory.
7632 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Implemented CONNECT and SHUTDOWN commands in the client.
7636 * Implemented CLOSE command to the client.
7638 * Added the function silc_idlist_find_server_by_name into the
7639 files silcd/idlist.[ch].
7641 Added the function silc_idlist_find_server_by_conn into the
7642 files silcd/idlist.[ch].
7644 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7646 * DIE command was renamed to SHUTDOWN. Updated the both code
7649 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7650 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7652 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7655 * Added function silc_server_create_connection function to create
7656 connection to remote router. My server implementation actually
7657 does not allow router to connect to normal server (it expects
7658 that normal server always initiates the connection to the router)
7659 so the CONNECT command is only good for connecting to another
7662 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7664 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7665 or some other client was kicked from the channel.
7667 Implemented the handling of the notify type to both client
7670 Implemented silc_server_send_notify_kicked to send the KICKED
7671 notify. It is used to send it to the server's primary router.
7673 * Implemented the KICK command into server and client.
7675 * Added `query' argument to the silc_idlist_get_client function
7676 to indicate whether to query the client from server or not if
7679 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7680 to indicate that the client is not channel founder.
7684 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7686 * Removed the rng context from SilcPacketContext structure and
7687 changed that the packet routine uses the Global RNG API.
7689 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Added support for quit message that client can "leave" on the
7692 channel when it quits the SILC. It is ditributed inside the
7693 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7695 Added silc_server_free_client_data that will take the
7696 signoff message as argument.
7698 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7700 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7702 * Updated parts of the protocol specification to keep it up
7705 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7708 payloads in one packet.
7710 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7711 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7712 use now the new List flag.
7714 * Also deprecated the following packet types: REPLACE_ID,
7715 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7717 * Added list support for Notify packet in server.
7719 * Added silc_server_send_notify_channel_change to send the
7720 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7721 the silc_server_send_replace_id.
7723 * Added silc_server_send_notify_nick_change to send the
7724 NICK_CHANGE notify type. Deprecates the function
7725 silc_server_send_replace_id.
7727 * Added silc_server_send_notify_join to send the JOIN notify type.
7728 Deprecates the function silc_server_send_new_channel_user.
7730 * Added silc_server_send_notify_leave to send LEAVE notify type.
7731 Deprecates the function silc_server_send_remove_channel_user.
7733 * Added silc_server_send_notify_cmode and
7734 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7735 types. Deprecates the silc_server_send_set_mode function.
7737 * Added SERVER_SIGNOFF notify type to indicate that server has
7738 quit. This means that all clients on the channel from that
7739 server will drop. This can be also used when netsplit happens.
7741 Deprecated REMOVE_ID packet type since it is not needed anymore
7744 Added silc_server_send_notify_server_signoff to send the
7745 SERVER_SIGNOFF notify type. Deprecates the function
7746 silc_server_send_remove_id.
7748 Added also silc_server_send_notify_signoff to send the
7749 SIGNOFF notify type.
7751 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7752 SILC protocol from this day on. Changed the protocol
7753 specification as well.
7755 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7756 notify type. It is used between routers to notify about
7757 topic changes on a channel.
7759 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7762 * Partly updated the protocol specification to comply with the
7763 changes now made. It is still though a bit outdated.
7765 * The JOIN notify type now takes one extra argument <Channel ID>.
7766 The packet used to be destined to the channel but now the
7767 JOIN type may be sent as list thus it is impossible to
7768 destine it to any specific channel. By adding this argument
7769 it is again possible.
7771 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7773 * Added CREDITS file. The CHANGES and CREDITS file will appear
7774 in the distribution as well.
7776 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7779 types in the server's silcd/packet_receive.c.
7781 * Implemented CMODE and CUMODE to work in router environment.
7783 * Fixed minor encoding and decoding buglet from the
7784 lib/silccore/silcmode.c.
7786 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7789 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7791 * Changed all SilcConfigServer* and silc_config_server* to
7792 SilcServerConfig* and silc_server_config*, respectively.
7795 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7797 * Associated the ID (client or server ID) to the Authentication
7798 Payload to avoid any possibility of forging. Updated the
7799 protocol specification and the code accordingly.
7801 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7803 * The RSA key length is now save to the RsaKey context in the
7804 key generation process in lib/silccrypt/rsa.c. The key length
7805 is now used to figure out the maximum size of the block allowed
7806 to be encrypted/signed.
7808 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7809 is equivalent to the silc_mp_mp2bin but does not allocate any
7812 * Changed silc_mp_mp2bin API to take length argument. If it is
7813 non-zero then the buffer is allocated that large. If zero, then
7814 the size is approximated using silc_mp_sizeinbase, which however
7817 * Created Global RNG API which is global RNG that application can
7818 initialize. After initializing, any routine anywhere in the
7819 code (including library) can use RNG without allocating a new
7820 RNG object. This was done to allow this sort of use of the
7821 RNG in code that has no chance to allocate RNG object. All
7822 applications currently allocate this and many routines in the
7823 library use this. Affected file lib/silccrypt/silcrng.[ch].
7825 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7826 it to use the Global RNG API.
7828 * Defined Authentication Payload into protocol specification that
7829 is used during SILC session to authenticate entities. It is
7830 used for example by client to authenticate itself to the server
7831 to obtain server operator privileges.
7833 Implemented this payload into the lib/silccore/silcauth.[ch].
7834 Implemented also routines for public key based authentication
7835 as the new protocol specification dictates.
7837 Moved definitions of different authentication methods from
7838 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7840 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7841 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7842 silc_pkcs_verify_with_hash functions into the file
7843 lib/silccrypt/silcpkcs.[ch].
7845 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7847 * The client entry's userinfo pointer must be always valid.
7848 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7849 will fail since it requires the userinfo. Now, the userinfo
7850 is allocated as "" if actual userinfo does not exist. Actually,
7851 it must exist and it is totally Ok to drop client connections
7852 that does not announce the userinfo. However, we will make
7853 this workaround for now.
7855 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7856 to return the remote port by socket.
7858 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7861 SILC_SERVER_PENDING_EXEC and added an new macro
7862 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7863 data or when error occurs while processing the pending command.
7865 Added new argument `destructor' into silc_server_command_pending
7866 and to the SilcServerCommandPending object. This destructor is
7867 now called after calling the pending callback or if error occurs
7868 immediately. If error occurs the actual pending callback won't
7869 be called at all - only the destructor. The destructor may be
7870 NULL if destructor is not needed.
7872 All this applies for client library code as well. Similar
7873 changes were made there as well for the pending commands.
7875 In the client, the application must now allocate the
7876 SilcClientCommandContext with the silc_client_command_alloc
7879 * Added reference counter to the SilcServerCommandContext. Added
7880 function silc_server_command_alloc and silc_server_command_dup
7883 Same type of functions added to the client library for the same
7886 * Removed the cmd_ident from IDListData away since it is now
7887 global for all connections. It is the command identifier used
7888 in command sending and with pending commands. The affected file
7891 * Added reference counter to the SilcSocketConnection objecet to
7892 indicate the usage count of the object. The object won't be
7893 freed untill the reference counter hits zero. Currently only
7894 server uses this, and client ignores it. The client must be
7895 set to use this too later. The affected files are
7896 lib/silccore/silcsockconn.[ch]. Added also the function
7897 silc_socket_dup to increase the reference counter.
7899 This was mainly added because it is possible that the socket
7900 is removed underneath of pending command or other async
7901 operation. Now it won't be free'd and proper DISCONNECTING
7902 flags, etc. can be set to avoid sending data to connection that
7903 is not valid anymore.
7905 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7906 the connection. After that it sets SILC_SET_DISCONNECTED.
7907 It is, however, possible that the socket data is not still freed.
7908 The silc_server_packet_process now checks that data is not
7909 read or written to connection that is DISCONNECTED. The socket
7910 get's freed when the reference counter hits zero.
7912 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7914 * Changed the client operation API: channel_message operation's
7915 `sender' is now the client entry of the sender, not the nickname
7916 and the `channel' is the channel entry, not the channel name.
7918 In the private_message operation the `sender' is now also the
7919 client entry of the sender not the nickname.
7921 Affected file is lib/silcclient/ops.h and all applications
7922 using the client operations.
7924 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7926 * Moved the calling of ops->connect() from connect_to_server_final
7927 into receive_new_id functin since that is the point when the
7928 client is actually allowed to send traffic to network. The
7929 affected file is lib/silcclient/client.c.
7931 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7933 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7934 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7935 (if needs broadcasting) instead of broadcasting the packets one
7936 by one which would make a burst in the network traffic.
7938 * Added `broadcast' argument to the functions in silcd/server.[ch]
7939 silc_server_create_new_channel[_with_id] to indicate whether
7940 to send New Channel packet to primary router.
7942 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Added new function into the silcd/server.[ch] files:
7945 silc_server_create_new_channel_with_id to create new channel with
7946 already existing Channel ID.
7948 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7949 lib/silccore/silcpacket.h. This packet is used t send list of
7950 Set Mode payloads inside one packet. Server uses this to set
7951 the modes for the channels and clients on those channels, that it
7952 announced to the router when it connected to it. The protocol
7953 specification has been updated accordingly.
7955 * The silc_server_new_channel did not handle the packet coming
7956 from normal server as it normally does not send that. However,
7957 when it announces its channels it does send it. Implemented
7958 the support for that.
7960 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7961 into the file lib/silccore/id.h.
7963 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7965 * Fixed memory leaks in the functions silc_idlist_del_client,
7966 silc_idlist_del_channel and silc_idlist_del_server in the file
7967 silcd/idlist.c. All of those leaked like a sieve.
7969 * Fixed some small memory leaks in the client's function
7970 silc_client_notify_by_server.
7972 * Added functions into silcd/server.c: silc_server_announce_clients,
7973 silc_server_announce_channels and silc_server_announce_server.
7974 These functions are used by normal and router server to announce
7975 to its primary router about clients, channels and servers (when
7976 router) that we own. This is done after we've connected to the
7979 These functions effectively implements the following packet types:
7980 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7981 and SILC_PACKET_NEW_ID_LIST.
7983 * Added new functions into the silcd/packet_receive.[ch]:
7984 silc_server_new_id_list, silc_server_new_channel_list and
7985 silc_server_new_channel_user_list to handle the incoming
7986 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7988 * Added support of changing Channel ID in the function
7989 silc_server_replace_id. If the server that announces a channel
7990 to the router already exists in the router (with same name but
7991 with different Channel ID), router is responsible to send
7992 Replace ID packet to the server and force the server to change
7993 the Channel ID to the one router has.
7995 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7996 client that the Channel ID has been changed by the router. The
7997 normal server sends this to the client. Client must start using
7998 the new Channel ID as the channel's ID.
8000 Implemented handling of this new type into lib/silcclient/client.c
8001 into the function silc_client_notify_by_server.
8003 * Added new function silc_idlist_replace_channel_id into the files
8004 silcd/idlist.[ch] to replace the Channel ID.
8006 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8008 * Call silc_server_command_identify_check always when processing
8009 the IDENTIFY command in silcd/command.c
8011 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8014 send keepalive packets. The packet can be sent by clients,
8015 servers and routers.
8017 Added function silc_socket_set_heartbeat into the file
8018 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8019 If not set, the heartbeat is not performed. The actual
8020 heartbeat is implemented in the low level socket connection
8021 library. However, application is responsible of actually
8024 Added silc_server_send_heartbeat to send the actual heartbeat
8025 packet into silcd/packet_send.[ch]. Server now performs
8026 keepalive with all connections.
8028 * Added silc_task_get_first function into lib/silcutil/silctask.c
8029 to return the timeout task with shortest timeout. There was a bug
8030 in task unregistration that caused problems. TODO has been
8031 updated to include that task system must be rewritten.
8033 * The client library will now resolve the client information when
8034 receiving JOIN notify from server for client that we know but
8035 have incomplete information.
8037 * Rewrote parts of silc_server_remove_from_channels and
8038 silc_server_remove_from_one_channel as they did not remove the
8039 channel in some circumstances even though they should've.
8041 * Encryption problem encountered in server:
8043 The LEAVE command used to send the Channel Key packet to the
8044 router immediately after generating it. However, the code
8045 had earlier sent Remove Channel user packet but not immediately,
8046 ie. it was put to queue. The order of packets in the router
8047 was that Channel Key packet was first and Remove Channel User
8048 packet was second, even though they were encrypted in the
8049 reverse order. For this reason, MAC check failed. Now, this
8050 is fixed by not sending the Channel Key packet immediately but
8051 putting it to queue. However, this is more fundamental problem:
8052 packets that are in queue should actually not be encrypted
8053 because packets that are sent immediately gets encrypted
8054 actually with wrong IV (and thus MAC check fails). So, packets
8055 that are in queue should be encrypted when they are sent to
8056 the wire and not when they put to the queue.
8058 However, the problem is that the current system has not been
8059 designed to work that way. Instead, the packet is encrypted
8060 as soon as possible and left to the queue. The queue is then
8061 just purged into wire. There won't be any fixes for this
8062 any time soon. So, the current semantic for packet sending
8065 o If you send packet to remote host and do not force the send
8066 (the packet will be in queue) then all subsequent packets to the
8067 same remote host must also be put to the queue. Only after the
8068 queue has been purged is it safe again to force the packet
8071 o If you send all packets immediately then it safe to send
8072 any of subsequent packets through the queue, however, after
8073 the first packet is put to queue then any subsequent packets
8074 must also be put to the queue.
8076 Follow these rules and everything works fine.
8078 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8080 * Added new function silc_server_remove_clients_by_server to
8081 remove all client entries from ID list when the server connection
8082 is lost. In this case it is also important to invalidate all
8083 client entires as they hold the invalid server entry. This
8084 fixes fatal bug when server has lost connection and will reconnect
8087 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8089 * Made some sanity checks to silc_server_daemonise like to check
8090 whether the requested user and group actually exists.
8092 * Added sanity check to SKE's silc_ske_responder_finish to check
8093 that the public and private key actually is valid.
8095 * Invalidate the client's nickname when receiving Replace ID
8096 packet and the Client ID is being replaced. This means that the
8097 server will query the nickname if someone needs it (client)
8100 * Sort the ID Cache in client library when the ID Cache data
8101 has changed (needs sorting).
8103 * Do not allow for SILC client to create several connections to
8104 several servers. The client does not support windows right now
8105 and generating multiple connections causes weird behaviour.
8107 Irssi-silc client does support windows and can handle several
8108 connections without problems, see: www.irssi.org and SILC plugin.
8110 * Fixed some places where client was added to the IDList. The
8111 rule of thumb is following (in order to get everything right):
8112 If the client is directly connected local client then the
8113 `connection' argument must be set and `router' argument must be
8114 NULL to silc_idlist_add_client function. If the client is not
8115 directly connected client then the `router' argument must
8116 bet set and the `connection' argument must be NULL to the
8117 silc_idlist_add_client function.
8119 * The funtion silc_server_packet_send_local_channel actually did
8120 not check whether the client was locally connected or not. It
8121 does that now. Fixed a bug related to LEAVE command.
8123 * Fixed Remove Channel User payload parsing bug in server's
8124 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8126 * The server's silc_server_save_channel_key now checks also the
8127 global ID list for the channel as it might not be in the local
8128 list. Fixed a bug related to LEAVE command.
8130 * Is this the end of the [<unknown>] buglet that has been lurking
8131 around for a long time? A little for loop fix in server's
8132 silc_server_command_whois_parse that is used by both IDENTIFY
8133 and WHOIS command. At least, this was a clear bug and a cause
8134 of one type of [<unknown>] buglet.
8136 * WHOIS and IDENTIFY commands call the function
8137 silc_server_command_[whois/identify]_check function even if
8138 we are not router server.
8140 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8142 * Added --with-gmp configuration option. If set the GMP
8143 is always compiled in the SILC source tree. If not set then
8144 it is checked whether the system has the GMP3 installed. If
8145 it has then the GMP won't be compiled (the system's headers
8146 and library is used), if it doesn't have it then the GMP is
8147 compiled in the SILC source tree.
8149 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8151 * Changed RSA private exponent generation to what PKCS #1
8152 suggests. We try to find the smallest possible d by doing
8153 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8154 not security fix but optimization.
8156 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Added new config entry [Identity] to fork the server and run
8159 it as specific user and group. A patch from Bostik.
8161 * Imported Dotconf configuration library into lib/dotconf.
8162 This will be used to create the SILC configuration files later.
8163 It will appear in the distsribution after this commit.
8165 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8167 * A big code auditing weekend happening. Auditing code for
8168 obvious mistakes, bugs and errors. Also, removing any code
8171 Removed files for being obsolete:
8173 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8174 inline in the file lib/silcutil/silcbuffer.h)
8176 o lib/silcutil/silcbufutil.c (the header has inline versions)
8178 Changed code to fix possible error conditions:
8180 o The buffer formatting routines now check that the destination
8181 buffer really has enough space to add the data. This applies for
8182 both buffer formatting and unformatting
8183 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8184 unformatting was changed to accomodate following rules:
8185 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8186 sent to the function while XXX_*STRING will not allocate or copy
8187 the data into the buffer. Instead it sets the pointer from the
8188 buffer into the pointer sent as argument (XXX_*STRING used to
8189 require that the pointer must be allocated already). This change
8190 makes this whole thing a bit more consistent and more optimized
8191 (note that the data returned in the unformatting with XXX_*STRING
8192 must not be freed now). The routines return now -1 on error.
8194 o Tried to find all code that use buffer_format and buffer_unformat
8195 and added return value checking to prevent formatting and
8196 especially unformatting errors and possible subsequent fatal
8199 o Changed ske->x and ske->KEY to mallocated pointers in
8200 lib/silcske/silcske.h. Fixed possible data and memory leak.
8202 o Added return value checking to all *_parse* functions. Fixed
8203 many memory leaks as well.
8205 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8206 so that buffer overflows would not happen. All code now also
8207 checks the return value as it can fail.
8209 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8211 * Added reconnection support to server if the normal server looses
8212 its connection to the router (for example if router is rebooted).
8213 The server performs normal reconnection strategy implemented
8214 to the server. Affected file silcd/server.c.
8216 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8218 * Added new packet type SILC_PACKET_SET_MODE that is used to
8219 distribute the information about changed modes (for clients,
8220 channels and clients channel modes) to all routers in the
8221 network. Updated the protocol specification accordingly.
8223 Added functions into silcd/packet_send.c and
8224 silcd/packet_receive.c: silc_server_send_set_mode,
8225 silc_server_set_mode.
8227 Added new files silcmode.[ch] into lib/silccore that implements
8228 the encoding and decoding of Set Mode Payload. Added new type
8229 SilcSetModePayload. Moved the definitions of different modes
8230 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8232 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8234 * Oops, a little mistake in server's connection authentication
8235 protocol. The protocol is not ended with FAILURE but with
8236 SUCCESS if the authentication is Ok. :) Affected file is
8239 * Implemented NICK_CHANGE notify handling in server in the file
8240 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8241 the local clients on the channel. After the changing nickname
8242 in router environment snhould work and the [<unknown>] nickname
8243 should appear no more.
8245 The silc_server_replace_id function that receives the Replace ID
8246 payload now sends the NICK_CHANGE notify type also in the file
8247 silcd/packet_receive.c
8249 * Changed WHOIS and IDENTIFY command to support the maximum amount
8250 of arguments defined in protocol specs (3328 arguments). This
8251 fixed a bug that caused problems when there were more than three
8254 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8256 * Added extra parameter, command identifier, to the
8257 silc_client_send_command so that explicit command identifier
8260 Changed that ID list routines uses specific command identifier
8261 when sending WHOIS/IDENTIFY requests to the server so that they
8262 can be identified when the reply comes back.
8264 Affected files lib/silcclient/command.[ch],
8265 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8267 * Added `sender' argument to silc_server_packet_send_to_channel
8268 to indicaet the sender who originally sent the packet to us
8269 that we are now re-sending. Ignored if NULL. Affected file
8270 silcd/packet_send.[ch].
8272 * Added some server statistics support in silcd/server_internal.h
8273 SilcServerStatistics structure and around the server code. Also
8274 send some nice statistics information when client is connecting
8277 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8279 * Fixed channel ID decoding in server's JOIN command reply in
8280 silcd/command_reply.c
8282 * Fixed braodcasting of replace ID payload to not to send it if
8283 we are standalone server in silcd/packet_receive.c.
8285 * Fixed all channel message sending routines to not to send
8286 packets to clients that has router set, since they are routed
8287 separately in the same function earlier. Affects file
8288 silcd/packet_send.c and all channel packet sending functions.
8290 * In USERS reply, res_argv[i] are not allocated, the table
8291 is allocated. Thus changed that free the table, not its
8294 * In server's whois_check and identify_check if the client is
8295 locally connected do not send any WHOIS commands - they are not
8298 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8300 * Fixed some minor bugs in client when sending WHOIS command. The
8301 arguments was in wrong order.
8303 * Removed statis function add_to_channel from server in
8304 silcd/command.c that was previously used with the joining but
8307 * Tested USERS command in router environment successfully with two
8308 routers, two servers and two clients.
8310 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8312 * Reorganized the USERS command and command reply in client library
8313 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8314 When the command is given by user we register a pending command
8315 callback that will reprocess the command after the reply has been
8316 received from the server. When reprocessing the packet we then
8317 display the information. Thus, the USERS information is displayed
8318 now in the command callback instead of in the command reply
8319 callback. The processing of the command is same as previously
8320 when server has sent the command reply in the JOINing process.
8322 * Added to USERS command in silcd/command_reply.c to join the client,
8323 we didn't use to know about, to the channel after we've created
8324 a client entry for it. Also, for clienet we did know already still
8325 check whether it is on the channel or not and add it if not.
8327 * Removed silc_server_command_join_notify as the function and its
8330 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8332 * Changed the client's pending command handling to the same as the
8333 server's pending command handling. It is also now possible to
8334 execute command reply functions from other command reply
8335 function as the function callbacks for commands and command
8336 replies are one and same. The pending commands are not static
8337 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8338 in client connection context. Thus, pending commands are server
8339 connection specific as it is convenient.
8341 Changed the function silc_client_command_pending and
8342 silc_client_command_pending_del and added new function
8343 silc_client_command_pending_check. Removed the
8344 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8347 * Added cmd_ident, current command identifier, to the client
8348 connection context in lib/silcclient/client.h to keep track on
8349 command identifiers used in command sending. Client's command reply
8350 function handling now supports the mandatory command identifiers.
8352 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8353 funtions in client to fully support pending command callbacks.
8355 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8356 as one of the arguments to the application in the command reply
8359 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8360 before first releasing SILC but came back. Now it is removed again
8361 and should come back nomore. The FORWARDED flag was used only
8362 by the JOINing procedure by forwarding the command packet to router.
8363 Now, the JOINing procedure has been changed to more generic (due
8364 to various router environment issues) and FORWARDED is not needed
8365 anymore for anything. The protocol specification is yet to be
8368 Now, removed silc_server_packet_forward from server and the flag
8369 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8371 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8373 * Renamed NAMES command to USERS command. The NAMES was named that
8374 due to historical reasons. Now it is renamed. Also, rewrote
8375 parts of the USERS command. The nickname list is not sent anymore
8376 by the server. Only Client ID and mode lists are sent in the USERS
8377 command. Changed this also to the protocol specification.
8379 The client now resolves the names and stuff after it receives
8380 the USERS list from the server when joining to the channel.
8382 * WHOIS and IDENTIFY commands has been changed to support multiple
8383 Client ID's per command. One can now search for multiple users
8384 in the network by sending only one WHOIS or IDENTIFY command.
8385 Changed the code and the protocol specifications.
8387 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8388 uses silc_server_command_whois_parse to parse the request. */
8390 * If normal server, do not parse the WHOIS and IDENTIFY requests
8391 before sending it to the router. Saves some time.
8393 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8395 * Fixed JOIN command on client library. Wrong number of arguments
8396 used to crash the client.
8398 * Added silc_server_channel_has_global function to check whether
8399 channel has global users or not.
8401 * Added silc_server_channel_has_local function to check whether channel
8402 has locally connected clients on the channel.
8404 * The silc_server_remove_from_one_channel now checks whether the
8405 channel has global users or not after given client was removed from
8406 the channel. It also checks whether the channel has local clients
8407 on the channel anymore. If it does not have then the channel entry
8408 is removed as it is not needed anymore.
8410 * The silc_server_notify now checks on JOIN notify whether the joining
8411 client is one of locally connected or global. If it is global then
8412 the channel has now global users on the channel and that is marked
8413 to the channel entry. Also, it now saves the global client to
8414 global list who is joining and JOINs it to the channel. This is
8415 for normal server, that is.
8417 Changed silc_server_send_notify_on_channel,
8418 silc_server_packet_relay_to_channel and
8419 silc_server_packet_send_to_channel check if we are normal server
8420 and client has router set (ie. global client) do not send the
8421 message to that client, as it is already routed to our router.
8423 * Implemented LEAVE notify type handling in silc_server_notify
8426 * Tested LEAVE command in router environment successfully. Tested
8427 with two routers, two servers and two clients.
8431 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8433 * Implemented SIGNOFF notify type handling in silc_server_notify
8436 * silc_server_remove_id now removes the client entry from all channels
8437 it has joined and thusly sends SIGNOFF notify type.
8439 * Rewrote the NAMES list generation in server by removing two excess
8440 loops. The lists are created now inside one loop.
8442 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8444 * silc_server_remove_channel_user checks now also global list
8445 for channel and client.
8447 * silc_server_new_channel_user checks now both local and global
8448 list for channel and client. Fixed a bug in client id decoding.
8449 Used to decode wrong buffer.
8451 * silc_server_channel_message checks now both local and global
8452 list for channel entry.
8454 * Tested channel joining (hence JOIN) in router environment
8455 successfully. Tested with two routers, two servers and two
8458 * Tested channel message sending in router environment successfully.
8460 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8462 * Added silc_server_save_channel_key into server.[ch] to save the
8463 received channel key in Channel Key payload processing. It is
8464 also used in JOIN command reply handling.
8466 Equivalent function silc_client_save_channel_key added into
8467 client.[ch] into client library.
8469 * Changed JOIN command reply to send information whether the channel
8470 was created or not (is existing already) and the channel key
8471 payload. Changed protocol specs accordingly.
8473 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8474 the request was sent by ID and not by nickname. Crashed on
8477 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8479 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8480 now correctly save the received data.
8482 * silc_server_free_sock_user_data now notifies routers in the
8483 network about entities leaving the network.
8485 At the same time implemented functions silc_server_remove_id
8486 and silc_server_send_remove_id to receive and send REMOVE_ID
8487 packets. The packet is used to notify routers in the network
8488 about leaving entities. The ID removed will become invalid in
8491 * Added function silc_idlist_del_server into server. Removes and
8492 free's server entry from ID list.
8494 * silc_server_private_message function now checks, if we are router,
8495 that the destination ID really is valid ID, naturally.
8497 * In router when NEW_ID packet is received (for new client) the
8498 hash of the Client ID is saved in the ID Cache but the
8499 client->nickname is set to NULL, instead of putting the hash
8502 IDENTIFY command now also checks that client->nickname must be
8503 valid. If it is not if will request the data from the server who
8504 owns the client. Added new function
8505 silc_server_command_identify_check.
8507 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8508 to set the command to already allocated Command Payload.
8510 * Tested private message sending in router environment with two
8511 routers, two servers and two clients. Fixed minor bugs and now
8514 * Fixed segfault from client's NAMES command. Used to crash if
8517 * Forwarded packets must not be routed even if it is not destined
8518 to the receiver. Changed server code comply with this.
8520 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8522 * Added `require_reverse_mapping' boolean value to ServerParams
8523 structure. If TRUE (not default) the server will require that
8524 the connecting host has fully qualified domain name.
8526 If the reverse mapping is not required and hostname could not be
8527 found the IP address is used as hostname.
8529 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8531 * Implemented version string checking to both client and server.
8532 The check is incomplete currently due to the abnormal version
8533 strings used in development version of SILC.
8535 * Changed all command functions in server to use the new
8538 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8540 * Changed char *data to unsigned char *data in ID Cache system to
8541 support binary data as ID Cache data. Changed code to support
8542 binary data in lib/silccore/idcache.c.
8544 * Renamed silc_server_packet_relay_command_reply to
8545 silc_server_command_reply as it is normal packet receiving
8546 function. Rewrote the function to accept command replys for
8547 servers and not only for clients.
8549 * Mark remote router always as registered server if we are connecting
8550 to it. Otherwise, commands sent by the router to us are ignored.
8552 * All ID List find routines now returns the ID Cache Entry pointer
8553 as well if requested.
8555 * WHOIS command works now in router environment, tested with two
8556 routers, two servers and two clients.
8558 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8559 in router environment (as it is almost equivalent to WHOIS) but
8560 hasn't been tested thoroughly. Added new functions:
8562 silc_server_command_identify_parse
8563 silc_server_command_identify_send_reply
8564 silc_server_command_identify_from_client
8565 silc_server_command_identify_from_server
8567 * Disabled route cache adding because adding two different ID's with
8568 same IP replaces the old cache entry thus giving wrong route.
8569 The entry->router->connection is always the fastest route anyway
8570 so route cache may not be needed. Of course, new routes maybe
8571 established after receiving the ID when the entry->router->connection
8572 might not be anymore the most optimal.
8574 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8576 * Add route cache for received ID for fast routing.
8578 * Added silc_server_packet_route to route received packet on router
8579 that is not destined to us.
8581 * Renamed silc_server_get_route to silc_server_route_get.
8583 * Added id_string and id_string_len fields into SilcServer to
8584 include encoded ServerID for fast comparing without excess
8585 encoding of the ID's.
8587 * Cleaned up WHOIS command on server side. Added following static
8590 silc_server_command_whois_parse
8591 silc_server_command_whois_check
8592 silc_server_command_whois_send_reply
8593 silc_server_command_whois_from_client
8594 silc_server_command_whois_from_server
8596 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8597 arguments in command replies. All command functions should be
8598 updated to use this macro.
8600 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8602 * Minor typo fixes on command reply handling on server.
8604 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8606 * Added silc_server_command_add_to_channel internal routine to add
8607 the client to the channel after router has created the channel and
8608 sent command reply to the server.
8610 * Added generic silc_server_send_command to send any command from
8613 * Use static buffer with ID rendering instead of duplicating data.
8615 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8617 * Fixed a channel user mode bug when joining to a channel server gave
8618 everybody channel founder rights, oops.
8620 * We mark ourselves as the router of the incoming server connection
8621 if we are router ourselves. This way we can check in some packet
8622 sending functions whether it is locally connected server. For
8623 incoming router connections we put NULL.
8625 * For router sending packets locally means now always sending the
8626 packet cell wide; to local clients and local servers. For normal
8627 server sending packet locally means sending it to only local
8630 * Fixed the JOIN command to really work in router environment. If the
8631 channel is created it is always created by the router. Router is
8632 also responsible of making the initial joining to the channel,
8633 sending JOIN notify to the sending server and distributing
8634 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8635 does not exist server doesn't do anything else but forward the
8636 command to the router which performs everything.
8638 * Added silc_server_send_channel_key function to send the Channel Key
8641 * Added silc_server_create_channel_key to create new channel key. The
8642 channel key is now re-generated everytime someone joins or leaves
8643 a channel, as protocol dictates. Note: channel->key_len is the
8646 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8648 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8649 packet_receive.[ch] to separate packet sending and receiving
8650 routines. The server.[ch] now includes everything else including
8651 actual packet processing (writing and reading data) and other
8654 Renamed silc_server_private_message_send_internal to
8655 silc_server_send_private_message. The routine is still though
8656 used only to relay private messages as server does not send
8657 private messages itself.
8659 Renamed silc_server_new_channel to silc_server_create_new_channel
8660 and added new function sicl_server_new_channel that handles the
8661 incoming New Channel packet. Added also new sending function
8662 silc_server_send_new_channel to send New Channel Payload.
8664 * Added new function silc_server_notify to process incoming notify
8665 packet to the server/router. Server may then relay the notify
8666 to clients if needed.
8668 * Added new function silc_server_new_channel_user to process incoming
8669 New Channel User packet. Router will redistribute the packet and
8670 send JOIN notify to its local clients and locally connected servers
8671 if needed. Normal server will send JOIN notify to its local client
8672 on same channel when received this packet. Added also corresponding
8673 sending function silc_server_send_new_channel_user to sent the
8676 * Added boolean route argument to send_notif_to_channel and
8677 packet_send_to_channel functions to attempt to route the packet
8678 if it is TRUE and send only locally if it is FALSE.
8680 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8682 * silc_server_replace_id now broadcasts the received replace ID
8683 packet if it is not broadcast packet already. The router must
8684 broadcast to inform other routers about changed ID.
8686 * Added backpointer to server's router into SilcServer context in
8687 silcd/server_internal.h.
8689 * Fixed silc_server_packet_broadcast to send correct broadcast
8692 * The channel key is now distributed to the local client as soon
8693 as it is received from the router (in router environment) so that
8694 no other packet may be sent for the channel until client has
8697 * silc_server_remove_channel_user now broadcasts the received
8698 Remove Channel User packet if it is not broadcast packet already.
8699 The router must broadcast to inform other routers about removed
8702 * Added users field into SilcPacketContext that is a reference count
8703 of the context. One can increase the reference count by calling
8704 silc_packet_context_dup which is now changed to just increase the
8705 reference count instead of duplicating the data. The reference
8706 count is decresed by calling silc_packet_context_free that will
8707 free the data after the reference count hits zero.
8709 For now on the packet context and everything allocated into it
8710 (including the raw packet from network) must be freed by calling
8711 the new silc_packet_context_free function. Added also new function
8712 silc_packet_context_alloc that must be used now to allocate the
8713 context. This also means that if a routine is asynchronous from
8714 silc_[client/server]_packet_parse_type the packet context must
8715 be duplicated by calling silc_packet_context_dup. Otherwise it
8716 gets free'd after silc_[client/server]_packet_parse_type returns.
8717 Also, one must remember that if packet is duplicated then its
8718 reference count must be decresed by calling the free function as
8719 many times as it was duplicated.
8721 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8722 from both client and server.
8724 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8726 * Made joining to a channel working in router environment.
8728 * Cleaned up JOIN command on server side and create function
8729 silc_server_command_join_channel internal routine to make the
8732 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8734 * Changed silc_command_pending list to SilcDList. Also, added
8735 `ident' field to SilcServerCommandPending structure to identify
8736 the reply and to call correct callback.
8738 Added silc_server_command_pending_check function to replace the
8739 corresnponding macro. The silc_command_pending list is not
8742 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8743 to set identifier to previously allocated Command Payload. It
8744 is used to set identifier for command when resending Command
8747 * Added silc_command_payload_encode_payload to encode Command
8748 Payload buffer from SilcCommandPayload structure.
8750 * Added silc_argument_payload_encode_payload to encode Argument
8751 payload buffer from SilcArgumentPayload structure.
8753 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8755 * Changed WHOIS command to support router connection on server side.
8756 The whois request is always sent to router unless the server is
8757 standalone server. After server has received the reply from the
8758 router will it send the reply to the client.
8760 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8761 broadcast received broadcast packet. The function is used only
8762 by router. The broadcast packet is always sent to the router's
8765 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8766 render given ID to printable string, for log files for example.
8768 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8770 * Made basic router to router connections working. At least they
8771 can now connect to each other but nothing really works the way
8772 they are supposed - yet.
8774 * Added new initiator token to RouterConnection configuration
8775 file in silcd/serverconfig.[ch]. It is used to tell whether we
8776 are the initiator to the remote router or whether we'll expect
8777 the other end to connect.
8779 * Moved registering of listener task to silc_server_init, hence
8780 the server starts listenning as soon as it is run, even if it
8781 does not have connections to other routers. Let's see how well
8784 * Changed default connection retry timeouts for more suitable in
8787 * Removed cipher and such arguments from silc_idlist_add_client
8788 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8789 Added new function silc_idlist_add_data to add the keys and stuff
8792 * Added SilcIDListData structure and added it to SilcClientEntry
8793 and SilcServerEntry as their first field in the structure. This
8794 way we can explicitly cast the ID entries to the SilcIDListData
8795 structure and get common data for the entries. In past, we had
8796 to first check what type of connection it is and then cast it to
8797 correct ID entry type. Now, we can directly cast the opaque
8798 pointer to the SilcIDListData (no matter what ID entry it actually
8799 is) and get the data needed.
8801 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8803 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8804 in some circumstances even if threre were timeout tasks, though not
8805 IO tasks, but tasks anyway. Now fixed.
8807 * Defined SilcServerConnection structure to hold connection specific
8808 stuff about directly connected servers and routers. The definition
8809 is currently in silcd/server_internal.h. I thought about having
8810 a bit more important role fro this struct but for now it is used
8811 only when connecting to other server (or router actually).
8813 * Added connecting retry support in server when connecting to
8814 router(s). The retry feature implement exponential backoff
8815 algorithm. Also, added SilcServerParams structure to hold default
8816 parameters for server. For now, it include these retry settings
8817 and are hard coded. After server is moded to be as Silc Server
8818 Library this structure will be more important.
8820 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8822 * Changed client librarys channel->clients table to SilcList and
8823 changed code accordingly.
8825 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8827 * Changed client's channel table to SilcList and changed code
8828 accordingly. Also changed SilcChannelClientEntry to include back-
8829 pointer to the channel so that client entry can use that structure
8830 as list as well and we have fast cross-reference to the channel.
8831 This change dramatically decreased the complexity of channel
8832 handling with client entry and vice versa (removed one extra
8833 loop when searching for channel entry from many functions).
8835 * Changed server->sim from table to SilcDList and changed code
8838 * NAMES command can now be used from user interface. It will show
8839 the user list on the channel, neatly.
8841 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8842 Code now saves realname of the user if it becomes available.
8844 * Renamed configure.in to configure.in.pre and made ./prepare
8845 script to automatically add correct version string to
8846 configure.in which it creates from configure.in.pre.
8848 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8850 * NAMES command reply now shows users mode with the nickname when
8853 * Moved silc_client_ch[u]mode[_char] functions from
8854 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8855 place sucks, they are utility functions and should be in some
8858 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8860 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8863 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8867 * Added TRQ (efficient deque and list library) into lib/trq. This is
8868 a very good list library that is currently used in the SILC. Defined
8869 SilcList API over the library because I didn't like the API very
8870 much. See lib/trq/silclist.h for the API and examples of how to
8871 use the API. Fixed various places in the code to use the new
8872 SilcList API. The SilcList is meant for lists that has a structure
8873 already defined as a list. It is not suitable to add just some
8874 context to the list (in TRQ, the context is the list actually).
8876 So, I defined SilcDList that can be used for the purpose where
8877 predefined list structure does not exit. This can be used as
8878 such list. Now some context just can be added to the SilcDList.
8879 Currently this list is not used in the SILC just yet, though there
8880 are a lot places where this can replace dynamically allocated
8881 tables and I will fix these places, later, to use SilcDList.
8882 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8883 and use TRQ internally).
8885 Also fixed some annoying warning messages that the original TRQ
8886 code generated. Also minor changes to TRQ's Makefile.in.
8888 * Added support for querying by Client ID to both WHOIS and
8889 IDENTIFY commands into server, as required by the protocol.
8891 * Removed method function pointers from SilcBuffer structure. They
8892 weren't used to anything and just increased the context size for
8893 no good reason. This change also made silc_buffer_alloc and
8894 silc_buffer_free functions inline functions.
8896 * Disabled command flooding detection support until it's fixed so
8897 that it accepts commands in but does not execute them more than once
8900 * Added silc_net_localhost(), to return local hostname, into
8901 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8902 that must be initialized before calling silc_client_init.
8904 * Added new function: silc_server_send_notify_on_channels to send
8905 notify messages to all channels client has joined. It is assured
8906 that the message is sent only once per client.
8908 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8909 lib/silcutil/silcutil.[ch] as silc_format function. The new
8910 function is generic and is used by server as well, not only by
8911 the logging routines.
8913 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8914 the provided version string was not acceptable. Added new function:
8915 silc_ske_check_version into lib/silcske/silcske.h. The function
8916 must be implemented by the application (client or server) and it
8917 does not reside in the SKE library. The function checks the version
8918 string remote end sent.
8920 * Added back pointers (to opaque context and to SilcSocketConnection)
8921 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8923 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8924 duplicate packet context structure.
8926 * Changed `notify' client operation to send same arguments as client
8927 receives from server except for ID's. ID's are mapped to correct
8928 ID entry and that is returned. Also, if channel entry is not sent
8929 by server but the notify is for channel the channel entry is sent
8930 to application (otherwise application doesn't know that it is for
8931 channel (library gets it from packet's Destination ID)).
8933 * Added silc_client_remove_from_channels into client library to
8934 remove a client from all channels it has joined to. Used when
8935 received SIGNOFF notify from server. Added also new function
8936 silc_client_replace_from_channels to replace old ID entry with
8937 new ID entry on all channels. Used when received NICK_CHANGE
8940 * Fixed ID Cache list handling in silc_idlist_get_client in
8941 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8942 to get (or query) client by ID.
8944 * Updated TODO list.
8946 * Added connection authentication status message defined by the
8947 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8948 support for these into the code in client and server side.
8950 * Added generic function silc_client_send_command to send any command
8951 with variable argument list. Application should use this function
8952 to send commands if the command functions provided by the library
8953 does not suite for the application's user interface needs.
8955 * Added new `failure' client operation. Application is notified about
8956 received failure packet if client is executing a protocol. In this
8957 case the protocol's execution has failed.
8959 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8960 is required by the protocol.
8962 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8963 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8966 * Added status flag to SilcSKE object to indicate realtime status
8967 of the SKE protocol.
8969 * Application receives now exactly same command reply arguments as
8970 the library receives from server. However, if ID is received the
8971 corresponding ID entry is returned to the application (eg. Client
8972 ID is mapped to correct SilcClientEntry entry and that is returned).
8973 Changed command_reply client operation due to this change.
8975 * Changed all ID's in commands and in command replys as ID Payloads.
8976 Change affected both client and server side codes.
8978 All ID's sent in SILC network (with execption of ID's in SILC
8979 Packet header) are sent in ID Payload to support variable length
8982 * Server now notifies nick changes and notifies all clients on
8983 the channels about the new nickname (about the new Client ID,
8986 * Implemented CMODE command to change channel modes. Supports all
8987 channel modes defined by the protocol specs except ban and invite
8988 lists. (Also, private channel key mode is supported but support for
8989 setting private channel key in client is missing, thus, this mode
8990 has no effect on client side (except that server requires that the
8991 client uses private channel key and normal channel traffic does not
8994 Also, invite mode works per se, but INVITE command does not work
8995 yet correctly, so you can set channel as invite only channel but
8996 inviting clients to the channel does not work (it is yet to be
8997 thought what's the best way to do it).
8999 * Added new command SILC_COMMAND_CUMODE to change user mode on the
9000 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
9001 Implemented CUMODE command to change user's mode on the channel.
9002 Supports all modes defined by the protocol specs.
9004 * Added NAMES command reply to return users modes on the channel.
9006 * Removed unnecessary and slow ciphers from lib/silccrypt.
9008 * Set SO_KEEPALIVE option to connection sockets by default.
9010 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9012 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9013 redefined the Notify Payload into protocol specs.
9015 * Added silc_id_payload_parse_id to get ID directly from raw
9018 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9020 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9021 accept searching by Client ID as well.
9023 * Added support for LEAVE and SIGNOFF notify types in client library.
9025 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9026 to parse ID Payload from raw data.
9028 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9030 * Added flags parameter into silc_ske_assemble_security_properties
9031 function in lib/silcske/silcske.[ch].
9033 * Changed notify client operation to fit better for notify messages
9034 sent by server. The notify payload received from server is now
9035 passed to the application (after parsing it to SilcNotifyPayload).
9036 It is application's responsibility to retrieve the arguments
9037 from the payload and show the message the way it wants. The message
9038 sent by server is implementation specific.
9040 * Changed public keys to comply with the protocol specification.
9041 Old public keys are not supported anymore and are not compatible.
9043 * Removed nickname from Channel Payload as the latest draft removed
9044 it. The client must resolve the nickname from the NAMES command
9045 reply received when it joined the channel.
9047 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9049 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9051 * Fixed some errors in protocol specification drafts.
9053 * Created lib/silccore/silcnotify.c to implement Notify Payload
9054 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9055 generic payloads described by protocol specifications. The file
9056 includes implementations for ID Payload and Argument Payload.
9058 * Changed Command Payload implementation to use the new Argument
9059 Payload. Changed command_xxxx_payload to command_payload_xxxx
9060 to comply with SILC coding conventions.
9062 * Added suppport for Argument Payload handling in Notify Payload
9063 implementation as protocol requires it. Added the new support
9064 into server and client lib as well.
9066 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9068 * Added support for multiple nicknames on same channel. [n] is
9069 added locally to the nickname if there are more than one same
9070 nicknames on the channel.
9072 * Server now sends all nicknames that matched WHOIS request.
9073 Client also shows the list received from server.
9075 * Added TOPIC command to client side. User can now set and show
9076 current topic on channel.
9078 * Added MOTD command to client and server. Also, server sends the
9079 motd when client connects to the server.
9081 * Changed version strings to comply ISO 8601.
9083 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9085 * Fixed protocol error handling in client library. It should now
9086 cope even if the SKE fails for some reason.
9088 * Made new protocol specification drafts for submitting to IETF.
9090 * Implemented TOPIC command to server in silcd/command.c.
9092 * Added two new notify types into lib/silccore/silcnotify.h:
9093 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9094 notify nickname change and topic setting/change on a channel.
9096 * API change of command_reply operation in client library. The
9097 application gets now the status type received from server as well.
9099 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9101 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9103 * Cras fixed and optimized the packet handling even further and
9104 it should work now. Minor change to the prototype of function
9105 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9107 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9109 * Added new function into lib/silcutil/silcschedule.[ch]:
9110 silc_schedule_with_fd to select() a specified fd. The function
9111 returns after timeout expires or data arrives or goes. The
9112 function is used by packet routines to wait that all data is
9113 received from network.
9115 * Fixed data reading from network in lib/silccore/silcpacket.c.
9116 The code now assures that all data is read from the fd and then
9117 continues packet processing. This was a bug fix since the code
9118 used to drop some data in some circumstances.
9120 * Added new function into lib/silcclient/client.[ch]:
9121 silc_client_start_key_exchange to start key exchange after
9122 connection has been established to server. The code internally
9123 now uses this funtion but its main purpose was to provide it
9124 for applications that perform their own connecting. After
9125 application has created a connection it merely calls this
9126 function to start the key exchange between client and server.
9127 The library takes care of everything else after that.
9129 Updated also lib/silcclient/README to explain the usage of
9132 * Do not send to application information that connection has
9133 been established. Application gets notified it by connect
9136 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9138 * Applied cras's patch to add silc_schedule_one function. The
9139 function runs scheduler once and returns.
9141 * Fixed the scheduler after cras messed it up. The timeout
9142 handling works now as it's supposed to work.
9144 * Added into lib/silccore/ silcnotify.h to include notify
9145 message types support. Changed silc_server_send_notify*
9146 functions, in server.[ch], to support those new notify types.
9147 Added the support for the notify types into client library,
9148 as well. Added new notify client operation into ops.h in
9151 * Changed silc_server_packet_send_to_channel to send normal
9152 packets instead of just channel message packets. The function
9153 is now used to send the notify packets to channels. It is not
9154 used to send channel message packets anymore, as server never
9157 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9158 va_arg()s as it seems to require it nowadays. I guess, if SILC
9159 is compiled with older va_arg() the new code should work anyway.
9161 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9163 * Splitted core library. Core library (lib/silccore) includes
9164 now only SILC protocol specific core (and common) components.
9165 Created new utility library (lib/silcutil) that includes more
9166 generic purpose stuff. The stuff for util library was taken
9167 from the old core library. This was minor and easy split.
9169 * Created SILC Client Library (lib/silcclient) that includes
9170 implementation of the SILC client without user interface. This
9171 was major move from silc/ directory. The code has been changed
9172 so that it is transparent towards the user interface. The
9173 silc/ directory includes now the same user interface as before
9174 and it uses the new client library. Read lib/silcclient/README.
9175 Basicly, the client library performs everything else related
9176 to SILC except user interface handling. Also, configuration
9177 files are considered to be part of user interface and library
9178 does not handle them.
9180 This change also changed a lot of structures, function naming etc.
9181 Most important change was that SilcClientWindow object was
9182 renamed to SilcClientConnection in the client library. Created
9183 also new file lib/silcclient/ops.h. Also added new files
9184 silc/local_command.[ch] and silc/client_ops.[ch].
9186 All these changes were made to make it easier for user interface
9187 designers to create what ever user interface for the SILC client
9190 It is also expected that the server will be moved to lib
9191 directory as well and SILC Server Library will be created;
9192 sometimes in the future.
9194 * Removed Local commands from lib/silccore/silccommand.h as
9195 they are application specific and new client library does not
9196 handle any of those anymore.
9198 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9199 old client implementation in silc/.
9201 * Added support for callback functions in SILC_LOG_* macros.
9202 Application can now set its own callbacks that will be called
9203 instead of using the default functions that will always print
9204 the debug messages to stderr (or stdout). Also, debugging can
9205 now be disabled by setting silc_debug to FALSE and re-enabled by
9206 setting it to TRUE. Note, that logging will still work even
9207 if debugging is disabled.
9209 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9210 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9211 silc_log_reset_debug_callbacks.
9213 * To enable debugging in silc client one must give now -d
9214 option on command line.
9216 * Changed silc_schedule_init to automatically allocate task queues
9217 if they are not allocated before calling it.
9219 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9221 * Added GMP 3.1 into math library.
9223 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9225 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9226 a channel in SILC network. The packet is used by servers and
9227 routers to notify other routers that user has left a channel.
9228 This little feature was missing until now. Added the feature
9229 to protocol specification as well.
9231 Added functions: silc_server_send_remove_channel_user and
9232 silc_server_remove_channel_user into server.[ch].
9234 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9235 lib/silccore/silcpacket.h. However, they are not implemented
9238 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9240 * Fixed joining to a channel and sending channel messages
9241 between server and router. The channel message sending should
9242 now work inside a cell.
9244 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9246 * Fixed the private message sending between server and router.
9247 The private message sending should now work inside a cell.
9249 * Added silc_server_replace_id into server.[ch] to replace
9250 existing ID in the SILC network.
9252 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9253 and silc_idlist_replace_server_id into idlist.[ch] in server.
9255 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9257 * Fixed the server to server connections. Server can again now
9258 connect to router. Router to router connections probably does
9261 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9263 * Added dynamic protocol registering support. Now protocols can
9264 registered and unregistered on the fly. Patch by cras.
9266 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9268 * Added lib/contrib directory to hold routines that some platforms
9269 don't have but are needed by SILC.
9271 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9272 into lin/contrib to provide getopt() and getopt_long() for
9273 those who don't have it.
9275 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9277 * Added AWAY command to client. When away message is set and
9278 client receives a private message packet the client automatically
9279 replies to the sender with the away message.
9281 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9282 bug seemed to be the cause of recent problems when compiling
9285 * Added version detection support to SKE protocol specification
9286 and added the new changes to the SKE implementation as well.
9287 There were other minor changes in the SKE protocol as well.
9289 Many changes in lib/silcske/silcske.[ch] and in
9290 lib/silcske/payload.[ch].
9292 * Added ^U functionality, clear input line. Patch from cras.
9294 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9296 * Mainly small bugfixes on core library. Fixed some debugging
9297 logging and buffer overflow in silclog.c.
9299 * Updated config.sub and config.guess on the distribution tree.
9301 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9303 * Added command lagging support in server. Client may execute
9304 commands now only once in two seconds.
9306 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9308 * Optimized packet reception. MAC computation and checking is now
9309 also more optimized. A lot previously duplicated code is now
9310 used as generic by both client and server.
9312 * Fixed key pair generation in clientutil.c
9314 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9316 * Added into lib/silccore/silcbufutil.[ch] new function;
9317 silc_buffer_realloc.
9319 * Moved generic packet sending/encryption functions to
9320 lib/silccore/silcpacket.[ch] from client and server. Some
9321 rewriting of the functions.
9323 * Moved all generic packet reception/decryption functions to
9324 lib/silccore/silcpacket.[ch] from client and server. The
9325 packet processing is now much cleaner in both client and server.
9326 These were major changes in both client and server.
9328 * Created many common functions in server to do packet sending.
9329 Previously code were duplicated a lot, this has been removed
9332 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9334 * Rewrote major parts of the ID cache system. Don't know
9335 whether it is better now or not but at least the API is more
9338 * Major rewrite on ID cache stuff on client because of the ID
9339 cache API changes. Added idlist.c to client.
9341 * Also major rewrite on ID cache stuff on server as well.
9342 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9343 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9344 in hand, instead they are all put into the ID cache system now.
9345 All server_idlist_* routines uses ID cache now instead of
9346 traversing its own lists (those lists does not exist anymore).
9347 SilcIDList though still exists. Also, SilcXXXEntry's are
9350 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9352 * Finally made the SKE implementation compliant to the protocol
9353 specification. All mp integers are now binary encoded as
9354 opposed being HEX encoded.
9356 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9359 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9360 functions: silc_[encode/decode]_pem. Also added function
9361 silc_encode_pem_file to PEM encode with newlines ('\n') for
9364 * SILC public keys are now encoded either PEM or binary. Same
9365 option is for private keys as well. By default private keys
9366 are binary encoded and public keys PEM encoded. Silly HEX
9367 encoding were removed.
9369 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9370 function to create fingerprints.
9372 * Fixed a bug in SHA1; does not change the original data anymore.
9374 * Partly implemented INFO command on client and server side.
9375 Fixed CLEAR command. Changes to SERVER command; show current
9376 server(s) when giving command without arguments. Added
9377 VERSION command to client.
9379 * Added check to server that unregistered connections cannot
9380 execute commands (unless it is specificly allowed).
9382 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9384 * Fixed screen refresh.
9386 * Fixed channel joining bug from client. On some circumstances
9387 client tried to join to a channel it had already joined.
9389 * Added public key verification process into client's protocol.c.
9390 The client now verifies the public key from user and saves
9391 it into ~./silc/serverkeys/ directory.
9393 Added into: clientutil.[ch]: silc_client_verify_server_key.
9395 * Changed SKE protocol's silc_ske_initiator_finish function
9396 to accept callback function that verifies the received public
9397 key. Removed old silc_ske_verify_public_key function.
9399 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9401 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9402 silc_pkcs_private_key[_data]_set.
9404 * Made the password and public authentication more cleaner in
9405 server's protocol.c.
9407 * Removed historic and obsolete protocol `channel_auth' from
9408 both client and server.
9410 * Removed wrong way of sending command status messages from
9411 server to client in server's command.c. The old way violated
9412 protocol specification.
9414 Changes to silccore/silccommand.[ch]: removed
9415 silc_command_encode_status_payload -> not needed anymore,
9416 changed silc_command_encode_payload_va to accept extra
9417 argument on variable argument list. The argument type must
9418 now be provided to the function. Also, added new function:
9419 silc_command_encode_reply_payload_va which is same as
9420 normal command_encode_payload_va except command status type
9421 is provided as extra argument.
9423 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9425 * Added ~./silc directory handling. The directory includes the
9426 public and private keys for the client.
9428 Added silc_client_check_silc_dir, silc_client_create_identifier
9429 and silc_client_load_keys.
9431 * Implemented SILC protocol compliant public key. Added public
9432 and private key saving to and loading from files.
9434 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9435 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9436 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9437 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9438 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9440 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9441 silc_pkcs_load_[public/private]_key.
9443 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9445 * Added silc_server_get_route (route.[ch]) to get connection
9446 data for the fastest route for given ID.
9448 * Implemented INVITE command on client and server. The command
9449 were re-defined in the SILC Protocol Specification and the
9450 implementation now complies with the specification.
9452 * Implemented PING command on client and server.
9454 * Implemented NAMES command on client and server. The server side
9455 supports currently only normal server not router server yet.
9456 Some changes to NAMES definition in SILC protocol specification.
9458 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9460 * Implemented LEAVE command on client and server.
9462 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9463 again. This change was made to the protocol as well. Server
9464 should not violate the protocol specification anymore.
9466 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9468 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9469 was tested. SOCKS4 was not but should work anyway.
