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

108 The <Requested Attributes> (defined in a separate document)
109 can be used to request additional information about user
110 not returned by standard WHOIS command. Defined that server
111 can send WHOIS command directly to client. Client provides
112 the requested attributes to the server. Updated the protocol
113 specs. Protocol TODO #4. Implementation is not done yet
116 * Renamed function silc_client_command_status_message to
117 silc_client_status_message. Affected files are

143 another command may attach to the same pending command reply
144 without requiring to resolve the same entry again. Added
145 support for adding multiple pending commands for one
146 command idenfier. Affected files lib/silcclient/command.[ch],
147 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
149 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

178 mask to the client. Updated protocol specs and the server.
179 Affected file is silcd/command.c.
181 * Added SILC session detachment/resuming support. It is possible
182 to detach by closing the network connection and then re-connect
183 and resume to the old client session. Added DETACHED user
184 mode that server will set for detached client. Added new
185 packet RESUME_CLIENT which is used to perform the resuming
186 process. Added DETACH command. Updated the protocol specs,

194 mask to the client. Updated protocol specs and the server.
195 Affected file is silcd/command.c.
197 * Changed the Killer's Client ID in KILLED notify to be just
198 any ID payload since router server is allowed to kill as well.
199 Updated protocol specs, client libary and server. Affected
200 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
201 and irssi/src/silc/core/client_ops.c.

216 may set to itself to tell server not send channel messages.
217 Other packets such as channel key packets are still sent.
218 Protocol TODO #23. Updated the protocol specs, client and
219 server. Affected files are lib/silccore/silcmode.h,
220 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
221 lib/silcutil/silcutil.c, silcd/command.c, and
224 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
226 * Redefined the Status Payload to include now two 8 bit fields,
227 instead of one 16 bit field. This now makes it possible to
228 send list of errors. Updated the protocol specs and the code
229 in core library, client library and server. Protocol TODO #1.
230 Affected files are lib/silccore/silccommand.[ch],
231 lib/silcclient/command_reply.[ch], silcd/command.c,
232 silcd/command_reply.c and silcd/packet_receive.[ch].
234 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
236 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
237 must be handled by the application and should tell the application
238 that an error message was already printed, and it should print the
239 config coords (line, filename, ...). Affected files are
240 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
242 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the

261 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Added STATS command to the protocol after all, to return
264 various statistical information about the network. It can
265 be used by clients to retrieve statistical information, and
266 servers may use it to to fetch cell and network wide
267 statistics from router. Updated the protocol specs and
268 implemented it to the server. Protocol TODO #16.
269 Affected files are lib/silccore/silccommand, silcd/command.[ch],
270 silcd/command_reply.[ch].
272 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
274 * The LIST command reply in client libary now adds new channel
275 entry if the returned channel doesn't exist yet in cache,
276 and returns the channel entry to the application in the
277 command_reply client operation. Affected file is
278 lib/silcclient/command_reply.c.
280 * Changed the channel message payload's MAC generation to
281 include the IV in the MAC as well. This way all relevant
282 parts of the channel message payload are authenticated also
283 with the channel message MAC (and not only by packet MAC).
284 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
285 Affected file is lib/silccore/silcchannel.c.
287 * Fixed the SKE to save the remote version, since the
288 silc_ske_parse_version mistakenly checked wrong version,
289 after it replaced the start payload. Affected files are
290 lib/silcske/silcske.[ch].
292 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

312 * Changed the silc_client_close_connection interface to not
313 need the SilcSocketConnection which should not be visible
314 to application. Affected files are lib/silcclient/client.c
315 and lib/silcclient/silcclient.h.
317 * Rewrote the text for Private Message Key Payload in the
318 protocol specification. Protocol TODO #11.

333 Protocol TODO #13. Affected files are silcd/command.c,
334 silcd/packet_receive.c, packet_send.[ch],
335 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
336 The killer's client entry is now returned to application in
337 the `notify' client operation.
339 * Fixed the Max Argument fields that had too large value set
340 in the protocol specs. Protocol TODO #14.
342 * Added the LEAVE command reply to return the ID of parted
343 channel. Updated protocol specs and implemented it to the
344 client and server. Protocol TODO #15. Affected files are
345 silcd/command.c, lib/silcclient/command_reply.c. The channel
346 entry is now returned to application in the `command_reply'

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

371 and lib/silcclient/client_ops_example.c.
373 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
374 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
375 the channel. Updated protocol specs and impelemented this
376 to client and server. Protocol TODO #6. Affected files are
377 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

380 Added new options m and M to CMODE command in Irssi SILC
381 client to set these modes.
383 * Deprecated all administrative commands from SILC protocol
384 since they are highly implementation specific commands.
385 Updated protocol specs. Moved the old commands in
386 implementations to private range of command types. Affected
387 files are silcd/command.c, lib/silcclient/command.c and
388 lib/silcclient/command_reply.c. Protocol TODO #8.

406 Affected file silcd/protocol.c.
408 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
410 * Some client implementations quit network by doing first LEAVE
411 and then immediately SIGNOFF (like Bombyx). We now do check
412 after a short time after LEAVE notify and check whether the
413 client is still valid after LEAVE, and if not we remove it from
414 cache. Affected file is lib/silcclient/client_notify.c.
416 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
418 * Merged version 1.1.4 of zlib. Even if it not currently in use,
419 it's good not to have security holes here.
421 * Fixed a negative refcount situtuation for the config context.
422 Affected file is silcd/serverconfig.c.
424 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

431 totally saved 16 bytes of memory per context after optimization.
432 Affected files are lib/silccore/silcpacket.[ch].
434 * Made strict checks for valid SILC IDs. Affected file is
435 lib/silccore/silcid.c.
437 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Changed the object argument for silc_cipher_register,
440 silc_hash_register, silc_hmac_register and silc_pkcs_register
441 to const. Affected files are lib/silccrypt/silccipher.[ch],
442 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
444 * Changed the silc_get_username and silc_get_real_name to
445 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
447 * Fixed the Irssi SILC Client to use the silc_get_username and
448 silc_get_real_name insted of glib routines since the glib
449 routines only corrupt stack. Fixes the Irssi SILC to work in
450 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
452 * Fixed the Irssi to not use g_get_home_dir since it crashes
453 or returns garbage on cygwin and corrupts stack. Added function
454 get_home_dir to Irssi routines. Affected files are
455 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
457 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
459 * Made some structure optimizations. SFTP memory FS MemFSEntry
460 entry structure. Optimized SilcTask structure. Optimized
461 SilcPacketContext structure.
463 Affected files lib/silcsftp/sftp_fs_memory.c,
464 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
466 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
468 * And yet again reverted back the config thing since Johnny
469 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
472 * Fixed memory leaks from config object. Affected files are
473 silcd/serverconfig.[ch].
475 * Added support for adding new connections to the server in rehash.
476 After rehash they take effect.
478 Added support for changing the maximum allowed connections in
479 rehash. The number can grow but going smaller is not supported.
481 Added function silc_server_num_sockets_by_remote to the
482 silcd/server_util.[ch].
484 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
486 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

489 public/private key and removed further checks in the code.
490 Affected files are silcd/serverconfig.[ch], server.c.
492 * Moved functions silc_server_drop() and silc_server_daemonise()
493 from server.c to silcd.c since they are stricly related to
494 the application activity.
496 * Reverted a small part of the automatic ref/unref since
497 it caused a double unref in some situations. Affected
498 files are silcd/silcd.[ch], server.c, serverconfig.c.

505 address. Affected file lib/silcutil/silcnet.c.
507 * Fixed the notify relaying to client. The HMAC to be used
508 with relayed packets ws wrong and caused decryption failure
509 at the client end. Affected file is silcd/packet_receive.c.
511 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
513 * Created new branch silc_protocol_1_0_branch.
515 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
517 * Changed the silc_server_config_* routines to be SilcServer
518 independent. They are now officially application specific code
519 and not part of generic server implementation. Affected files
520 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
522 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Added automatic referencing of config context in the
525 silc_server_config_alloc, and automatic unreferencing in the
526 silc_server_config_destroy. Affected files are
527 silcd/serverconfig.[ch], silcd/silcd.c.
529 * Fixed the silc_log_quick handling in the logging routines.
530 It didn't log quickly when it was TRUE. Affected file is
531 lib/silcutil/silclog.c. Also the flush delay was set even
532 if it was 0 in config file. Affected file is
533 silcd/serverconfig.c.
535 * Added support for changing key pair of the server in rehash.
536 Affected file silcd/server.c.
538 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
540 * Fixed the TOPIC_SET notify to not cras. It changed the topic
541 too early, before getting the channel entry. Affected file
542 is silcd/packet_receive.c.
544 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
546 * Added functions silc_server_config_[ref/unref], these are used
547 to prevent that the config object is destroyed.
549 No longer directly affect global variables silc_log_quick and
550 silc_log_delay, they are first cached inside the config object
551 and then applied with silc_server_config_setlogfiles().
553 silc_server_config_set_defaults() is now internal to
554 serverconfig.c, there are no reasons to show this internal stuff
557 Affected files are silcd/serverconfig.[ch].
559 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
560 fprintf's to stderr, since some code may be executed again after
561 the server went into the background. Affected files are
564 * Added rehash support. Added function silc_server_rehash() that
565 will perform all the basic tasks of the rehashing procedure.
567 * Added command line option `-x, --hexdump'. This will enable the
568 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
569 The option `--hexdump' implies `--debug'.
571 * Fixed a bad bug in the logging APIs (silcutil library) where
572 the application would crash after calling silc_log_reset_all().
574 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
576 * Fixed the KICKED notify handling in client library to
577 correctly remove the channel and all entries from the
578 channel when I was kicked. This bug crashed the client.
580 Fixed yet another but in KICKED notify handling to remove
581 the kicked client correctly from the channel.
583 Affected file is lib/silcclient/client_notify.c.
585 * Fixed a minor bug in looking up correct client entry
586 in KICKED notify in server. Affected file is
587 silcd/packet_receive.c.
589 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
590 sources correctly to distribution. Fixes --with-gmp option.
592 * Removed the manual rehashing from ID Cache, and changed it
593 to use the SILC Hash Table's auto rehash feature. Affected
594 file is lib/silccore/silcidcache.c.
596 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
598 * Fixed a bug in the silc_client_nickname_format function that
599 handles the multiple same nickname formatting. Two clients
600 with same nickname caused problems after the first one left
601 and rejoined. It didn't format the nickname correctly.
602 Affected file is lib/silcclient/idlist.c.
604 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
606 * Don't change the topic if olod topic is same as new one.
607 Affected file is silcd/packet_receive.c.
609 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
611 * Added cross-reference support to the SILC Documentation
612 generator. All types across all HTML files are now cross-
613 referenced. Affected files util/robodoc/generator.c and
614 scripts/silcdoc/silcdoc.
616 * Added file lib/silcutil/silctypes.h to include all the
617 arithmetic type definitions and some macros. Removed
618 includes/bitmove.h and moved macros to silctypes.h.
620 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
622 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
624 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Added `type' argument to silc_id_payload_parse_id function which
627 now returns the type of the ID to the sent pointer. Affected
628 file is lib/silccore/silcid.[ch].
630 * Added check for CMODE_CHANGE notify type that mode change is
631 allowed by the sender. Affected file silcd/packet_receive.c.
633 * Added check for CUMODE_CHANGE notify type that mode change is
634 allowed by the sender. Affected file silcd/packet_receive.c.
635 Added the ID type as CUMODE_CHANGE notify type as argument
636 to the `notify' client operation. Affected files are
637 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
639 * Added function silc_client_add_server to the client library.
640 Added support for resolving also channel and server info when
641 received unknown entity in notify packet. Affected files are
642 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
644 * Added function silc_command_get_status to return the command
645 status from the command reply's argument payload. Affected files
646 are lib/silccore/silccommand.[ch].
648 * Added check for KICKED notify type that the kicking is
649 allowed by the client. Affected file silcd/packet_receive.c.
651 * Created function silc_get_input which can be used to get input
652 (echo on or off) from user on command line. Affected files are
653 lib/silcutil/silcutil.[ch].
655 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
657 * Optimized silc_server_packet_relay_to_channel function.
658 Added new function silc_channel_message_payload_encrypt which
659 can be called directly if channel message payload needs to
660 be encrypted and is already encoded (no need to call _encode
661 function). Packet relaying is now done by router without any
662 extra memory allocations. Affected files are
663 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
666 * Fixed the INVITE notify handling. It took wrong arguments
667 as invite list and invite delete. Affected file is
668 silcd/packet_receive.c.
670 * Added check for TOPIC_SET notify type that the topic change is
671 allowed by the client. Affected file silcd/packet_receive.c.
673 * Added check for INVITE notify type that inviting is allowed by
674 the client. Affected file silcd/packet_receive.c.
676 * Changed the silc_server_client_on_channel to return the
677 SilcChannelClientEntry as well. Moved the function
678 silc_server_check_cmode_rights to server_util.[ch].
679 Affected files are silcd/server_util.[ch], silcd/command.c.
681 * Added function silc_server_check_umode_rights to check whether
682 changing client's user mode is allowed. Added check for
683 UMODE_CHANGE notify type that the umode change is allowed
684 by the client. Affected files are silcd/server_util.[ch],
685 silcd/packet_receive.c and silcd/command.c.
687 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
689 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
690 ID length. It ignored that ID can be IPv6 based as well.
691 Affected file lib/silccore/silcpacket.h.
693 * Fixed the silc_id_id2str and silc_id_str2id to take the
694 IPv6 address offset's into consideration. Affecte file is
695 lib/silccore/silcid.c.
697 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
699 * Fixed the internal Unix scheduler functions to check for
700 NULL context they may receive. The affected file is
701 lib/silcutil/unix/silcunixschedule.c.
703 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
705 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
706 can specify different directory with --home command line
707 parameter. Affected files irssi/src/silc/core/client_ops.c,
710 * SILC-specific commands aren't now executed if the active server
711 isn't of SILC-type, so there won't be problems with having
712 IRC and SILC protocol support in same client. Affected files
713 irssi/src/silc/core/silc-channels.c, silc-servers.c,
716 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
718 * Improved the signal support in SILC Schedule. Added new
719 function silc_schedule_signal_call which is used by application
720 to mark a signal to be called. It is now safe to perform
721 any kind of tasks in signal callbacks since it is guaranteed
722 that the application specified signal callback is called
723 after the signal is over. Affected files are
724 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
726 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
728 * Added `name' field to SilcChannelPrivateKey to represent
729 application given name for the key. Moved also the context from
730 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
731 Added the `name' argument also to the function
732 silc_client_add_channel_private_key.
734 Added function silc_client_current_channel_private_key to set the
735 current channel private key in use.
737 Added "change" command to KEY command which can be used to change
738 the current channel private key. Bound the command also to
741 Also affected files lib/silcclient/client_channel.c,
742 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
744 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
746 * Added silc_rng_get_byte_fast function in to the
747 lib/silccrypt/silcrng.[ch].
749 * Changed the interface of silc_packet_assemble and the
750 silc_packet_send_prepare. If silc_packet_assmble is now
751 called the application does not call silc_packet_send_prepare
752 because the library will call it automatically. These
753 interfaces now also return a reference to the outgoing buffer
754 which includes the assembled packet, which the application can
755 use to encrypt the packet.
757 Affected files are lib/silccore/silcpacket.[ch],
758 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
759 silcd/packet_send.c, server_backup.c and packet_receive.c.
761 * Fixed a packet sending bug on very high load, where outgoing
762 packet queue wasn't handled correctly and packets got corrupted.
763 Affected files are lib/silcutil/*/silc*sockconn.c,
764 lib/silcclient/client.c and silcd/server.c.
766 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
768 * Added macro SILC_PACKET_DATALEN which can be used during
769 packet assembling to check whether the data to be added to
770 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
771 len is truncated until it fits it.
773 Added checks for maximum length of channel message payload and
774 private message payload also.
776 Added checks for maximum packet length in server and in
779 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
780 lib/silcclient/client.c, lib/silccore/silcchannel.c and
781 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
782 lib/silcclient/client_prvmsg.c.
784 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
786 * Added silc_server_packet_queue_purge call to the
787 silc_server_disconnect_remote to assure that all data in the
788 queue before disconnecting is sent to the network. Affected
791 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Added the deleting of server's own ID cache entry to the
794 silc_server_free function. Free also everything else that
795 has been allocated in silc_server_init. The affected file
798 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Added functions silc_parse_version_string, silc_version_to_num,
801 and silc_ske_parse_version to parse SILC protocol style version
802 strings. Affected files lib/silcutil/silcutil.[ch] and
803 lib/silcske/silcske.[ch].
805 * Added new configuration params: version_protocol, version_software
806 and version_software_vendor to specify what version the remote
807 host must at least be to be able to connect to server. The vendor
808 string can be regex matched too. Added new function
809 silc_server_connection_allowed to check maximum number of allowed
810 connections, and allowed versions for incoming connections.
811 Affected files are silcd/server.c, server_util.[ch] and
814 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Added preliminary support for signals in scheduler. The
817 signals we care about are now blocked always when the scheduler
818 is locked. This way we can synchronise the use of signal with
819 scheduler. It is guaranteed that when signal occurs the scheduler
820 is not locked, and thus new tasks can be safely added to the
823 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
824 to silc_schedule_internal_init and silc_schedule_internal_uninit.
825 Added new platform specific routines
826 silc_schedule_internal_signals_[un]block and
827 silc_schedule_internal_signal_[un]register.
829 Added new functions to SILC Schedule API:
830 silc_schedule_signal_[un]register. Each signal that application
831 is going to use should be registered to the scheduler.
833 Affected files are lib/silcutil/silcschedule.[ch],
834 lib/silcutil/*/silc*schedule.c.
836 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Check for unauthenticated client and server in the
839 silc_server_new_client and silc_server_new_server functions.
840 Affected file silcd/packet_receive.c.
842 * Added function silc_string_is_ascii to check whether given
843 string is 7-bit ASCII string. Affected files are
844 lib/silcutil/silcutil.[ch].
846 * Added function silc_id_is_valid_server_id into the
847 silcd/serverid.c and added checking for valid Server ID's in
848 silc_server_new_server. The Server ID must always be based
849 on the server's public IP address.
851 * Added logging of DISCONNECT packet message in the server.
852 Affected file silcd/server.c.
854 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
856 * Changed all library interfaces that use Global RNG to also
857 accept SilcRng as argument. Affected files are
858 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
859 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
860 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
861 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
864 * Added function silc_pkcs_generate_key to the
865 lib/silccrypt/silcpkcs.[ch] for applications so that they
866 don't need to do pkcs->pkcs->init calls anymore.
868 * Remove SilcSocketConnection from the SFTP API since it really
869 wasn't needed there. The application has the information
870 saved in its contexts anyway and the SFTP layer doesn't need
871 know about it. Affected files lib/silcsft/silcsftp.h and
872 lib/silcsftp/sftp_[server/client].c.
874 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
875 The SilcSimContext is not SilcSim.
877 * Fixed possible buffer overflows in silc_id_render in the
878 lib/silcutil/silcutil.c.
880 * On EPOC the global crypto module lists are not used at all
881 in the crypto library. Added support for using the constant
882 algorithm list on EPOC. Affected files are
883 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
886 * Fixed the handling of third parameter of KICKED notify, since
887 it was mistakenly updated to SILC Protocol 1.0 even though it
888 is to be included in 1.1. Since it is not in 1.0 it is not
889 mandatory, and this fix now handles it only if it is provided,
890 and it is not error if it is not provided. Affected file
891 lib/silcclient/client_notify.c.
893 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
896 client. Affected file irssi/src/silc/core/client_ops.c.
898 * Merged with Irssi 0.8.4 from irssi.org CVS.
900 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
902 * Check for valid socket connection in client entries before
903 sending any messages. Fixes a crash, but doesn't fix some
904 other underlaying bug that is lurking there. Affected
905 file silcd/packet_send.c.
907 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
909 * $usermode, $cumode and $cumode_space expandos shouldn't do
910 anything with non-SILC server records. Affected file
911 irssi/src/silc/core/silc-expandos.c
913 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
915 * Fixed the silc_net_check_[host/local]_by_sock to support
916 IPv6 bound sockets as well. Now they can return IPv6 addresses
917 as well. Affected file lib/silcutil/silcnet.c.
919 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
920 Affected lib/silcutil/unix/silcunixnet.c.
922 * Fixed ID rendering (at least on some platforms, not NetBSD)
923 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
925 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
927 * Added silc_hash_public_key and silc_hash_public_key_compare
928 functions to be used with SilcHashTable. They can be used to
929 hash public keys and compare public keys in hash table. Affected
930 file lib/silcutil/silcutil.[ch].
932 * Added support for specifying multiple public keys for Client
933 connection section in server configuration file. This makes it
934 possible to accept multiple public keys from same host, or to
935 make a section that accepts any incoming host, and have the
936 accepted public keys listed in the section.
938 Added functions silc_sever_[find/get]_public_key, added the
939 support for this actually to all connection sections but only
940 the Client section is currently allowed to specify multiple
943 Affected files are silcd/server.c, server_internal.h,
944 command.c, protocol.c, server_util.[ch], packet_receive.c.
946 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
948 * Merged Irssi 0.8.2 from irssi.org CVS.
950 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
952 * If silc_debug is TRUE, also output standard logging messages
953 to stderr with the debug output.
955 Made silc_log_reset_all() flushing all channels before returning.
956 Also fixed some documentation typos.
958 Affected files are lib/silcutil/silclog.[ch].
960 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
962 * Fixed the server to check correctly the amount of connections
963 from single host, by checking also the type of the connection.
964 Fixed also the comparison of number of connections and number
965 of allowed connections. Affected files are silcd/server.c,
968 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
970 * Fixed the USERS command reply to save the user's mode on the
971 channel as well. Fixed JOIN command reply to check whether a
972 client is on channel already and not join it twice. Affected
973 file lib/silcclient/command_reply.c.
975 * Added new file silc-expandos.c into irssi/silc/core/ to return
976 various stuff for various signal for the statusbar etc. updating.
977 Now Irssi SILC client prints channel user modes etc. on the
980 * The user mode (like server/router operator changes) is now shown
981 on the Irssi SILC client's statusbar. The affected files are
982 irssi/src/silc/core/client_ops.c, silc-expandos.c.
984 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
986 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
987 to SILC_SCHEDULE_[UN]LOCK macros.
989 * Added more error printing to logs in server code. Affected
990 files silcd/server.c and silcd/protocol.c.
992 * Fixed -S option parsing in Irssi SILC Client. Affected file
993 irssi/src/silc/core/silc-core.c.
995 * Added silc_buffer_alloc_size function. Affected file is
996 lib/silcutil/silcbuffer.h.
998 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1000 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1001 constants. Affected files in
1002 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1005 * Changed the internal SFTP Memory FS table to const. Affected
1006 file lib/silcsftp/sftp_fs_memory.c.
1008 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1010 * Fixed the buffer formatting and unformatting routines to
1011 check the size of 64 bits types with sizeof(). Affected
1012 file is lib/silcutil/silcbuffmt.c.
1014 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1016 * Removed 0.6.x backwards support.
1018 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Changed all integer type names:
1021 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1022 to avoid collisions with other libraries using same type names

1028 silc_net_gethostbyname[_async]. If it is TRUE it will return
1029 IPv6 address over IPv4. If FALSE IPv4 address is returned
1030 even if IPv6 address was found. Affected files
1031 lib/silcutil/silcnet.[ch].
1033 * Added support silc_net_create_connection[_async] to fallback
1034 to IPv4 address if IPv6 address could not be used (like if
1035 it doesn't work on a specific system). Affected file in
1036 lib/silcutil/unix/silcunixnet.c.
1038 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1047 application does not need to define them. Affected file
1048 includes/silcincludes.h.
1050 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1051 old name went against naming convention. Applications now
1052 include "silcclient.h" instead of "clientlibincludes.h".
1053 Removed includes/clientlibincludes.h, it is redundant now.
1055 * Renamed includes/version.h to silcversion.h.
1057 * Added really preliminary support for OS/2 into the util
1058 library. Only thread & mutex API is implemented, others
1059 are still to be implemented. Created the lib/silcutil/os2/
1060 directory. Created also file includes/silcos2.h.
1062 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1093 * Added `user_count' to the SilcChannelEntry which now tells the
1094 number of users on the channel. The user count is now saved
1095 in normal server of global channels as well. Affected files
1096 silcd/server.c, idlist.h, packet_receive.c and command.c.
1098 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1099 include file utility functions.

1115 the SKE interface a bit.
1117 * Fixed padding problem in PKCS#1. The padding was not actually
1118 random since the random number generator was used incorrectly.
1119 This security bug affects only when encrypting with PKCS#1, and
1120 it is not currently used at all in SILC. SILC only use signing
1121 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1184 Affected files irssi/src/silc/core/silc-core.c,
1185 irssi/src/fe-text/silc.c.
1187 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1189 * Added new configuration options and blocks:
1190 keepalive_secs, reconnect_count, reconnect_interval,
1191 reconnect_interval_max, reconnect_keep_trying and
1192 require_reverser_lookup. Added ConnectionParam block, and
1193 implemented the connection parameters when connecting as
1194 initiator and when accepting connections as responder.

1206 the connection configuration object from the SilcServerConnection
1207 object instead of finding it during the connecting phase.
1208 Added the configuration object to SilcServerConnection struct.
1209 Affected files silcd/server_internal.h, server.c.
1211 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1213 * Add the client on channel after it was resolved at the
1214 channel message receiving, and it was not already on the
1215 channel. Affected file lib/silcclient/client_channel.c.
1217 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1233 authentication to be set at the same time.
1235 Added `prefer_passphrase_auth' setting in config file which
1236 can be used to set to prefer passwd auth if both passwd and
1237 public key is set. If not set, public key is preferred.
1238 This has effect only when being initiator (responder will try
1241 Added support for authentication with passphrase and public key
1242 at the same time. The passphrase is tried first always since
1243 it is faster to check.
1245 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1247 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1294 zero port also if the hostname is NULL because it could not
1297 Call file transfer monitor callback now also if error occurs
1298 during key agreement protocol.
1300 Changed the silc_client_file_send interface to return the
1301 SilcClientFileError instead of session id. The session ID
1302 is returned into pointer provided as argument.
1304 Check that the file exists locally before sending the
1305 file transfer request at all.
1307 Affected file lib/silcclient/client_ftp.c, silcapi.h.

1341 the table with foreach callback. The current entry may
1342 become invalid in the callback but it was referenced after
1343 the callback returned.
1345 Do not allow auto rehashing of hash table during the
1346 silc_hash_table_foreach operation, for same reasons as it is
1347 not allowed for SilcHashTableList. Affected files are

1374 * Fixed a bug in hash table tarversing. While the hash table
1375 is traversed with SilcHashTableList the table must not be
1376 rehashed. It is now guaranteed that auto rehashable tables
1377 are not rehashed while tarversing the list. Also defined that
1378 silc_hash_table_rehash must not be called while tarversing
1379 the table. Added function silc_hash_table_list_reset that must
1380 be called after the tarversing is over. The affected files are
1381 lib/silcutil/silchashtable.[ch].
1383 * Changed all hash table traversing to call the new
1384 silc_hash_table_list_reset in server and in client library.
1386 * Added function silc_client_on_channel to return the
1387 SilcChannelUser entry if the specified client entry is joined
1388 on the specified channel. This is exported to application as
1389 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1397 * Fixed the WHOWAS command's reply sending to support the
1398 lists correctly. Affected file silcd/command.c.
1400 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1402 * When sending JOIN command to router for processing the
1403 sender's old command identifier was not saved back to the
1404 sender's command context, fixed now. The affected file is
1407 * Create the key in JOIN command of the router did not return
1408 the channel key, added check for this. Affected file is
1411 * Fixed a channel ID update bug in JOIN command reply. Do
1412 not directly upgrade the ID but call the function
1413 silc_idlist_replace_channel_id if the ID was changed.
1414 Affected file silcd/command_reply.c.
1416 * Fixed memory leaks from command calling if it would fail.

1504 local entry will always get the unformatted nickname.
1505 Affected file lib/silcclient/idlist.c.
1507 * Fixed some double frees from client library commands.
1508 Affected file is lib/silcclient/command.c.
1510 * Fixed CUMODE command in server to assure that no one can

1528 exchange with server. The affected file is
1529 lib/silcclient/client.c.
1531 * The server's public key is now saved using the IP address
1532 of the server and not the servername for the filename.
1533 The hostname public key filename is checked as an fall back
1534 method if the IP address based filename is not found.
1536 Fixed the GETKEY command to save the fetched server key
1537 in correct filename.
1539 Print the remote server's hostname now when new key is
1540 received during connection process. Affected file is

1558 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1560 * Do not save client history information in SERVER_SIGNOFF.
1561 Fixes the bug in normal server that it does not detect
1562 the client becoming valid after the server becomes back
1563 online. Affected file silcd/server_util.c.
1565 * Added `sock_error' field into the SilcSocketConnection
1566 context. When error occurs during socket operation (read
1567 or write) the error is saved. Added also new function
1568 silc_socket_get_error to return human readable socket error
1569 message. Affected files are lib/silcutil/silcsockconn.[ch],
1570 lib/silcutil/unix/silcunixsockconn.c, and
1571 lib/silcutil/win32/silcwin32sockconn.c.
1573 * The server now prints the socket error message in the
1574 signoff for client. Affected file silcd/server.c.
1576 * Fixed the `created' channel information sending from router
1577 to server in JOIN command. Checks now whether the channel
1578 really was created or not and set it according that.
1580 Fixed the JOIN command to use the client entry's current
1581 ID during the joining procedure instead of the one it sent
1582 in the command (it is checked though), since it can change
1583 between the packet processing and command processing, and
1584 would just case unnecessary pain in the client end. Affected
1585 file silcd/command.c.
1587 * Fixed a channel key payload sending to use correct channel
1588 ID when the server was forced to change the channel's ID by
1589 router. Router sent the key payload with the old Channel ID.
1590 Affected file silcd/packet_receive.c.
1592 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1594 * Call silc_server_save_channel_key only if the key payload
1595 was provided in the JOIN command's command reply. Affected
1596 file silcd/command_reply.c.
1598 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1600 * Fixed silc_mp_sizeinbase to return the value correctly with
1601 MPI. Affected file lib/silcmath/mp_mpi.c.
1603 * Fixed the stop_server signal to correctly stop the scheduler
1604 and gracefully stop the server when SIGTERM or SIGINT signals
1605 are received. Affected file silcd/silcd.c.
1607 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1609 * Simple handling of TERM and HUP signals. Also added some log
1610 flushing call around. Affected file is
1613 * Fixed small bugs in silclog.c. Now buffering output will take
1614 effect after 10 seconds since startup: This will ensure that
1615 no important startup messages are lost. Also output redirection
1616 will preserve original format ([Date] [Type] message).
1617 Affected file is lib/silcutil/silclog.c.
1619 * Added two options to the config file, in the logging section:
1620 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1621 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1623 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Do not print the warning about log files not being initialized
1626 more than once to avoid excess logging. Affected file is
1627 lib/silcutil/silclog.c.
1629 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1630 the SIM copying in make install in Makefile.am.pre.
1632 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1634 * Rewritten silclog APIs. Globally interesting changes follows:
1635 silc_log_set_files() changed to silc_log_set_file().
1636 silc_log_set_callbacks() changed to silc_log_set_callback().
1637 ROBOdoc documented silclog header file.
1638 SilcLogCb now returns bool to wether inihibit the default
1639 handler or not (to keep the old behaviour return always TRUE).
1640 The new APIs should also fix the problem of the
1641 silcd_error.log file that was written in the current directory.
1644 Log files streams will remain opened after silc_log_set_file()
1645 call, means less CPU usage notably on high traffic servers.
1646 File streams are now full buffered, and flushed to the disk
1647 every 5 minutes, lesses HD activity and CPU usage.
1648 Messages can be redirected, allowing admins to configure
1649 one single logfile for all server messages.
1650 the silc_log_quick global variable to activate fast-logging.
1651 Affected files lib/silcutil/silclog.[ch]
1653 * Changed some code to conform new silclog APIs. Affected
1654 files are doc/example_silcd.conf.in, silcd/server.c
1655 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1658 * Fixed a memory leak that could occur in some situations.
1659 Affected file silcd/serverconfig.c.
1661 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1663 * Added the silc_client_del_client to remove the client from
1664 all channels as well. Affected file lib/silcclient/idlist.c.
1666 * Fixed the client library to correctly remove the client
1667 from all channels when the client entry is being destroyed.
1668 Affected file lib/silcclient/client_notify.c, command.c.
1670 * Added auto-nicking support to the client library. If the
1671 applicatio now sets client->nickname it will be sent to the
1672 server after connecting by the library. This way for example
1673 SILCNICK (or IRCNICK) environment variables will have effect
1674 and always change the nickname automatically to whatever
1675 it is wanted. Affected file lib/silcclient/client.[ch].
1677 * Renamed silc_server_command_bad_chars to the
1678 silc_server_name_bad_chars and moved it to the
1679 silcd/server_util.[ch]. Added also new function
1680 silc_server_name_modify_bad to return nickname that
1681 includes bad characters as new nickname without those
1682 bad characters. This check and modify is now used in
1683 silc_server_new_client when the username is initially set
1684 as nickname, so it must be checked to be valid nickname.
1685 Affected file silcd/packet_receive.c.
1687 * The nickname length is now taken from the packet for real
1688 and not trusted to strlen() since it clearly can return
1689 wrong length for nickname including bad characters. This
1690 also applies to channel names. Affected file silcd/command.c.
1692 * Removed the lib/silcsilm/modules directory. Modules are now
1693 compiled into the lib/silcsim. Fixed the copying of the
1694 modules to follow symbolic links in Makefile.am.pre.
1696 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1698 * Fixed silc_string_regexify list creation. Fixes bugs with
1699 BAN and INVITE commands in server. The affected file is
1700 lib/silcutil/unix/silcunixutil.c.
1702 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Removed the command destructor entirely from the server's
1705 command and command reply routines. It is not needed, and
1706 its usage was buggy and caused crashes. Affected files are
1707 silcd/command[_reply].[ch].
1709 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1711 * Cancel protocol and NULL sock->protocol if timeout
1712 occurred during protocol. Affected file silcd/server.c.
1714 * Cancel protocol timeouts always before calling the final
1715 callback, to assure that after final callback is called
1716 no other state will be called for the protocol anymore.
1717 Affected file silcd/protocol.c.
1719 * Print error log if incoming connection configuration could
1720 not be found. Affected file silcd/server.c.
1722 * Fixed JOIN command to correctly save the founder mode
1723 to the client on normal SILC server, when the channel
1724 was created by the router. Affected file silcd/command.c.
1726 * Fixed LIST command (hopefully) to send correct reply
1727 packets. Affected file silcd/command.c.
1729 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * The silc_packet_receive_process now returns FALSE if the
1732 read data was invalid packet, and TRUE if it was ok.
1734 The server now checks that if unauthenticated connection
1735 sends data and its processing fails the server will close
1736 the connection since it could be a malicious flooder.
1738 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1740 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1742 * Make sure the warning about error opening a log file is
1743 printed only once and not everytime it fails (produces
1744 too much useless log). Affected file lib/silcutil/silclog.c.
1746 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1748 * Made the silc_server_daemonise() function more readable.
1749 Affected file silcd/server.c.
1751 * Pid file is now optional, the user may comment it out from
1752 the config file. Removed define SILC_SERVER_PID_FILE, we
1753 don't need a default any longer. Affected file
1754 configure.in.pre, lib/Makefile.am.pre.
1756 * Make some use of the pid file. The server now dies at startup
1757 if it detects a valid pid file on his path. The server would
1758 die anyway in this circumstance, because of the bind() failure.
1759 Affected file silcd/silcd.c.
1761 * No longer compiling lib/dotconf.
1763 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1765 * Fixed JOIN command parsing not to crash. Affected file
1766 lib/silcclient/command.c.
1768 * Fied the NICK_CHANGE notify to add the new client entry
1769 even it is resolved. This removes an <[unknown]> nick
1770 thingy bug in the client. Affected file is
1771 lib/silcclient/client_notify.c.
1773 * Do not try to allocate 0 bytes (efence does not like it)
1774 in lib/silccore/silccomand.c when encoding payload.
1776 * Do not take IRCNICK as nickname in Irssi SILC client since
1777 it is not possible to set nickname before hand connecting
1778 the server (TODO has an entry about adding auto-nicking
1781 * Changed the silc_server_command_pending to check whether
1782 there already exists an pending entry with the specified
1783 command, command identifier and pending callback. This is
1784 to fix IDENTIFY and WHOIS related crashes that may register
1785 multiple pending commands with same identifier. Affected
1786 file silcd/command.c.
1788 * Fixed the server to reconnect to the router even if it
1789 was already reconnecting and EOF was received. This to
1790 fix a possibility that the server wouldn't ever try to
1791 auto-reconnect to the router. Affected file silcd/server.c.
1793 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Fixed the server's password authentication to use the
1796 length of the locally saved password, and not the one
1797 sent in the packet. Affected file silcd/protocol.c.
1799 * Fixed same password authentication problem in the
1800 Authentication Payload handling routines in
1801 lib/silccore/silcauth.c.
1803 * Yet another password authentication problem fixed with
1804 channel password handling in silcd/command.c.
1806 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1808 * If first character of string in silc_parse_userfqdn is '@'
1809 then do not parse it. Affected file is
1810 lib/silcutil/silcutil.c.
1812 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Fixed minor bug in IDENTIFY command reply sending, which
1815 caused various weird problems during JOIN when it was
1816 resolving names for users. Affected file silcd/command.c.
1818 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1820 * Fixed the IDENTIFY command reply sending to chech better valid
1821 clients. It was possible to send incomplete list of replies.
1822 Affected file silcd/command.c.
1824 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added silc_client_command[s]_[un]register functions now to
1827 dynamically register the commands in client library. Removed
1828 the static table of commands. This allows the client library
1829 to call commands without causing the application to know about
1830 what commands library has called.
1832 Removed the INFO command reply kludge to detect when the command
1833 was called by library. Now library use its own command reply
1834 function for INFO command.
1836 Added function silc_client_command_call to call a command.
1837 Application can use it to call command, not access the structure
1840 Now all commands that are sent by the client library (not
1841 explicitly sent by application) use own command reply functions.
1843 Affected files around lib/silcclient/ and in
1844 irssi/src/silc/core/.
1846 * Fixed the WHOIS command reply sending to chech better valid
1847 clients. It was possible to send incomplete list of replies.
1849 Fixed the WHOIS and IDENTIFY to send the request to router
1850 if normal server did not do it and did not find any results.
1852 Affected file silcd/command.c.
1854 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Moved the internal data from SilcClient context into its
1857 own file, not accesible to application. Affected files
1858 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1859 and other files in client library.
1861 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1863 * Added doc/examples installation target in Makefile.am.pre.
1866 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1868 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1869 commands the found client entry will be removed from the
1870 cache, after notifying application about the error. Affected
1871 file lib/silcclient/command_reply.c.
1873 * Changed the /MSG to check for exact nickname user gave, and
1874 not let `nick' match `nick@host' if it is only one found. Now,
1875 user must type the exact nickname (like nick@host2) even if
1876 there are no more than one same nicks found. This is to avoid
1877 a possibility of sending nickname to wrong nickname since
1878 `nick' could match `nick@host'. Affected file is
1879 irssi/src/core/silc-servers.c.
1881 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Do not print "you are now server operator" or similar when
1884 giving /away command. Affected files are
1885 irssi/src/silc/core/client_ops.c, silc-servers.h.
1887 * Made the silc_server_command_pending_error_check to send
1888 the same command reply payload it received back to the
1889 original sender of the command. This way all arguments
1890 that was received by the server will be received by the
1891 client too. Affected file silcd/command.c.
1893 * Added the silc_idcache_add to return the created cache entry
1894 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1896 * Add global clients to expire if they are not on any channel.
1897 This is because normal server will never know if they signoff
1898 if they are not on any channel. The cache expiry will take
1899 case of these entries. This is done by normal servers only.
1900 The affected files are silcd/command_reply.c,
1901 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1903 * If server receives invalid ID notification for WHOIS or
1904 IDENTIFY and the ID exists in the lists, it is removed.
1905 Affected file silcd/command_reply.c.
1907 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1908 in client then client entry that it matches is searched and
1909 the nickname is printed on the screen for user. Affected
1910 file irssi/src/silc/core/client_ops.c.
1912 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1914 * Use cache entry expire time in the LIST command reply to
1915 purge old entries from the cache after the LIST command
1916 reply has been received. This way we don't have non-existent
1917 entries in the cache for too long. Affected file is
1918 silcd/command_reply.c.
1920 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1922 * If we are normal server, and we've not resolved client info
1923 in WHOIS or IDENTIFY from router, and it is global client,
1924 we'll check whether it is on some channel. If it is not
1925 then we cannot be sure about its validity and will resolve it
1926 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1927 file silcd/command.c.
1929 * Search channel by name (if possible) rather than by ID
1930 in IDENTIFY command's command reply. Affected file is
1931 silcd/command_reply.c.
1933 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1936 Updated specs and implemented it. Affected file silcd/command.c,
1937 silcd/packet_send.c and silcd/packet_receive.c.
1939 * Implemented the <founder auth> payload handling in the JOIN
1940 command. If provided all conditions for channel joining
1941 except requirement to provide correct passphrase can be
1942 overrided by the channel founder. Updated the protocol specs.
1943 Affected file silcd/command.c.
1945 Added support for founder auth in JOIN command in client
1946 library. Fixed the parsing of the JOIN command now to support
1947 all options as they should be. The affected file is
1948 lib/silcclient/command.c.
1950 * Optimized the WHOIS and IDENTIFY commands to send the request
1951 to router only if it includes nicknames or other names. If
1952 they include only IDs then check the local cache first before
1953 routing. Affected file is silcd/command.c.
1955 * Added channels topic announcements. Affected file is
1956 silcd/packet_receive.c and silcd/server.c.
1958 * Fixed the silc_server_send_notify_topic_set to really destine
1959 the packet to channel. Affected file silcd/packet_send.c.
1961 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1962 library. Affected file lib/silcclient/client_notify.c.
1964 * Added UMODE announcements. Affected file silcd/server.c.
1966 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1968 * Memory leak fixes in:
1970 lib/silcutil/silcsockconn.c
1971 lib/silcske/silcske.c
1972 lib/silcske/groups.c
1974 lib/silccrypt/silcpkcs.c
1975 lib/silccore/silccommand.c
1976 lib/silccore/silcidcache.c
1981 * ROBOdoc documented the lib/silcske/groups.h file and a
1982 bit changed the interface for better.
1984 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1986 * Update the client entry context in the ID cache after
1987 nick change. Affected file lib/silcclient/command.c.
1988 Fixes the CUMODE command when regaining founder privileges,
1989 and a little WHOIS problem.
1991 * Fixed silc_net_gethostbyname to correctly call the
1992 inet_ntop. Affected file lib/silcutil/silcnet.c.
1994 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1996 * Added IPv6 support checking to the configure.in.pre, added
1997 also --enable-ipv6 option to override the check. Affected
1998 file configure.in.pre.
2000 * The silc_thread_create now calls the start function
2001 directly if threads support is not compiled in. Removes
2002 ugly #ifdef's from generic code. Affected files are
2003 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2005 * Added silc_net_gethostby[name/addr]_async to asynchronously
2006 resolve. Affected files are lib/silcutil/silcnet.[ch].
2008 * Added support for rendering IPv6 based server, client and
2009 channel IDs. Affected file lib/silcutil/silcutil.c.
2011 * Added support for creating IPv6 based server IDs. Affected
2012 file is silcd/serverid.c.
2014 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2016 * Added silc_net_gethostby[addr/name] into the
2017 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2018 routines. Added silc_net_is_ip[4/6]. Affected file is
2019 lib/silcutil/unix/silcunixnet.c. All routines that take
2020 address as argument now supports both IPv4 and IPv6 addresses.
2022 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2024 * Fixed LIST command reply sending in server. Affected file
2027 * Server now sends the kicker's client ID in the KICK notify
2028 to the kicked client. Affected file silcd/command.c.
2030 * The client library now parses the kickers client ID and
2031 UI displays it. Affected files lib/silcclient/client_notify.c
2032 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2034 * Made all payload parsing function prototypes consistent.
2035 They all take now const unsigned char * and uint32 pair as
2036 the payload data instead of SilcBuffer. Changes all around
2037 the source tree. Other unsigned char* -> const unsigned char*
2038 changes around the tree as well.
2040 * Optimized SFTP client and server packet sending not to
2041 allocate new buffer for each packet but to recycle the
2042 first allocated buffer. Affected files are
2043 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2045 * Optimized the SFTP client to use SilcList instead of
2046 SilcDList for requests, because it is faster. Affected file
2047 is lib/silcsftp/sftp_client.c.
2049 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2050 into lib/silccore/silcid.[ch].
2052 Renamed silcpayload.[ch] into silcargument.[ch].
2054 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * If client entry is deleted with active key agreement
2057 session, abort the session.
2059 The silc_client_abort_key_agreement now calls the completion
2060 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2062 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2065 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2067 * Don't use __restrict in older GCC's. Affected file is
2068 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2070 * silc_net_localhost now attempts to reverse lookup the
2071 IP/hostname. Affected file lib/silcutil/silcnet.c.
2073 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2074 command. It can be used to gain founder privileges at
2075 the same time when joining the channel.
2077 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2078 kicker's client ID as well. Updated protocol specs.
2080 Defined that the server must send SILC_COMMAND_IDENTIFY
2081 command reply with error status to client who sent
2082 private message with invalid client ID.
2084 Updated the protocol specification.
2086 * Added silc_server_send_command_reply to send any
2087 command reply. Affected file silcd/packet_send.[ch].
2089 * Added silc_id_payload_encode_data to encode ID payload
2090 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2092 * The server now send IDENTIFY command reply with error
2093 status if client ID in private message is invalid. Affected
2094 file silcd/packet_receive.c.
2096 * Save the server key file with server's IP address in
2097 the filename instead of hostname. The affected file is
2098 irssi/src/silc/core/client_ops.c.
2100 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2102 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2105 * Added libtool support for compiling shared objects in
2106 lib/silcsim. Affected file configure.in.pre and
2107 lib/silcsim/Makefile.am. Original patch by cras.
2109 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2111 * Pid file configuration, and server's config file fixes
2112 patch by toma. Updated CREDITS file.
2114 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Fixed silc_client_channel_message to not try to decrypt
2117 the message twice if it resolved the destination client
2118 information. This could cause of dropping one channel
2119 message. Affected file lib/silcclient/client_channel.c.
2121 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2123 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2124 lib/silcclient/client.c. This function is used when the SILC
2125 Client is run under some other scheduler, or event loop or
2126 main loop. On GUI applications, for example this may be
2127 desired to used to run the client under the GUI application's
2128 main loop. Typically the GUI application would register an
2129 idle task that calls this function multiple times in a second
2130 to quickly process the SILC specific data.
2132 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2134 * Fixed silc_server_drop() for dropping the supplementary
2135 groups as well, this could cause a security hole on some
2138 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2140 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2143 * Write PID file after dropping privileges. Added -F option
2144 to run server on foreground. A patch by debolaz.
2145 Affected files silcd/server.c, silcd/silcd.c.
2147 * Fixed MOTD to return the MOTD file server name. Affected
2148 file silcd/command.c.
2150 * Added INFO command reply handling to the Irssi SILC Client.
2151 Affected file irssi/src/silc/core/client_ops.c.
2153 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Fixed the silc_idcache_list_* routines to really support
2156 the dynamic list. Fixes a crash. Affected file is
2157 lib/silccore/silcidcache.c.
2159 * Fixed the LIST command reply to really call LIST command's
2160 pending callbacks. Affected file silcd/command_reply.c.
2162 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2164 * Update conn->local_entry->nickname after giving NICK
2165 command. Affected file lib/silcclient/command.c.
2167 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2169 * Added the [pid] option to the silcd configuration file
2171 Affected files: serverconfig.[ch] and silcd.c
2173 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2175 * Save fingerprint in WHOIS command reply in server.
2176 Affected file silcd/command_reply.c.
2178 * Fixed NICK commands pending callback registration.
2179 Affected file lib/silcclient/command.c.
2181 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Use ++server->cmd_ident when sending commands in server,
2184 instead of random number. Affected file silcd/command.c.
2186 * Fixed GETKEY command reply to call actually GETKEY pending
2187 command callbacks. Affected file silcd/command_reply.c.
2189 * A bit stricter check for nicknames. Check for same nickname
2190 in NICK command also. Affected file silcd/command.c.
2192 * Do not call INFO command everytime client ID changes, only
2193 during first connecting. Affected file lib/silcclient/client.c.
2195 * Set the new nickname only after successful command reply for
2196 NICK command is returned by server. Affected file
2197 lib/silcclient/command.c.
2199 * Remove nicknames from nicklist during server_signoff notify.
2200 Should fix /NAMES bit more. The affected file is
2201 irssi/src/silc/core/silc-channels.c.
2203 * Added `fingerprint' field to the SilcIDListData in the
2204 silcd/idlist.h to hold the fingerprint of the client's
2207 Send the fingerprint of the client's public key in WHOIS
2210 Affected files silcd/command.c, and silcd/idlist.[ch].
2212 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2213 create fingerprint from given data.
2215 * Show the fingerprint of the client's public key in WHOIS.
2216 Affected files irssi/src/module-formats.[ch] and
2217 irssi/src/silc/core/client_ops.c.
2219 * Format the multiple same nicknames also during JOIN and
2220 NICK_CHANGE notifys. Affected file is
2221 lib/silcclient/client_notify.c.
2223 * Do not print error on screen for invalid private message
2224 payload since it can come if someone is sending private
2225 messages with wrong key. Affected file
2226 lib/silccore/silcprivate.c.
2228 * Fixed multiple concurrent /PING crash. Affected file
2229 lib/silcclient/command.c.
2231 * Changed the wrong ID encoding. All IP addresses must be
2232 in MSB first order in encoded format. They were encoded
2233 wrong and was in LSB format. Affected files are
2234 silcd/serverid.c, lib/silcutil/silcutil.c.
2236 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2238 * Call the `connect' client operation through the scheduler
2239 in case of error. Affected file lib/silcclient/client.c.
2241 * Call the `failure' client operation even if the error
2242 occurred locally during a protocol. Affected file is
2243 lib/silcclient/protocol.c.
2245 * Added support of sending LIST command to router from normal
2246 server. This way normal server can get list of all channels
2247 in the network too. Fixed the channel list sending in the
2248 server too. Affected files are silcd/command.c, and
2249 silcd/command_reply.[ch].
2251 * Added silc_server_update_channels_by_server and
2252 silc_server_remove_channels_by_server. They are used during
2253 disconnection of primary router and in backup router protocol.
2254 Affected file silcd/server_util.[ch], silcd/server.c and
2255 silcd/server_backup.c.
2257 * Fixed channel adding to global list in IDENTIFY command
2258 reply in server. Affected file silcd/command_reply.c.
2260 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * If the incoming packet type is REKEY or REKEY_DONE process
2263 that packet always synchronously. Fixes yet another MAC
2264 failed error on slow (dialup) connections. Affected file
2265 lib/silcclient/client.c and silcd/server.c.
2267 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Call check_version SKE callback for initiator too. Affected
2270 file lib/silcske/silcske.c.
2272 * Implemented fix for security hole found in the SKE that was
2273 fixed in the specification few days back; the initiator's
2274 public key is now added to the HASH value computation.
2275 Added backwards support for the old way of doing it too, for
2276 old clients and old servers. Affected file is
2277 lib/silcske/silcske.c.
2279 * Enabled mutual authentication by default in SKE. If initiator
2280 is not providing mutual authentication the responder will
2281 force it. This will provide the proof of posession of the
2282 private key for responder. The affected files are
2283 lib/silcclient/protocol.c and silcd/protocol.c.
2285 * Do not cache anymore the server's public key during SKE.
2286 We do mutual authentication so the proof of posession of
2287 private key is done, and if the server is authenticated in
2288 conn auth protocol with public key we must have the public
2289 key already. Affected file silcd/protocol.c.
2291 * Added new global debug variable: silc_debug_hexdump. If
2292 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2293 file lib/silcutil/silclog.[ch].
2295 * Fixed compilation warning due to char * -> const char *.
2296 Affected files lib/silcutil/silcnet.h, and
2297 lib/silccore/silcauth.[ch].
2299 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2301 * Fixed CMODE command when new channel key was created. If
2302 the creation failed the old key was removed. Next time giving
2303 same command would crash the server since the old key was
2304 freed already. Affected file silcd/command.c.
2306 * Fixed the silc_server_announce_get_channels to not crash
2307 on reconnect. Affected file silcd/server.c.
2309 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Added silc_log_set_debug_string function to set a regex
2312 string to match for debug output. Only the function names,
2313 or filenames matching the given debug string is actually
2314 printed. This way it is possible to filter out those debug
2315 strings that user is not interested in.
2317 Fixed a bug in silc_string_regexify.
2319 Affected files lib/silcutil/silclog.[ch], and
2320 lib/silcutil/unix/silcunixutil.c.
2322 * Changed the -d options in both server and Irssi SILC client
2323 to take the debug string as argument. Affected files
2324 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2326 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2328 * Added silc_hash_babbleprint to create a Bubble Babble
2329 Encoded fingerprint. The encoding is developed by Antti
2330 Huima (draft-huima-babble-01.txt), and it creates human
2331 readable strings out of binary data. Affected file
2332 lib/silccrypt/silchash.[ch].
2334 * Print the babble print now in addition of fingerprint as well
2335 in Irssi SILC client. Affected files are
2336 irssi/src/fe-common/silc/module-formats.[ch],
2337 irssi/src/fe-common/silc/core/client_ops.c.
2339 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2341 * Fixed a security problem found in SKE. The initiator's
2342 public key too is now added to the HASH hash value creation
2343 which is signed by the responder to create the SIGN value.
2344 This will prevent anyone in the middle to lie to the responder
2345 about the initiator's public key. If this is done now, the
2346 man in the middle will get caught. Updated the protocol
2349 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Better installation directory handling. Configure module
2352 paths and other paths automatically to example_silc* files
2353 in doc/. A patch by toma.
2355 * Fixed compiler warning from MPI library, and from SILC RNG.
2358 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2359 It can be configured with ./configure. A patch by toma.
2361 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Find correct make to use in prepare-clean. A patch by
2364 toma. Affected file prepare-clean.
2366 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2368 * Added irssi variables use_auto_addr, auto_bind_ip,
2369 auto_bind_port and auto_public_ip.
2371 * Changed the interface for silc_client_send_key_agreement
2372 in lib/silcclient/silcapi.h
2376 irssi/src/silc/core/silc-core.c
2378 lib/silcclient/silcapi.h
2379 irssi/src/silc/core/silc-channels.c
2380 lib/silcclient/client_keyagr.c
2383 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2385 * Added silc_pkcs_public_key_compare to compare two
2386 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2388 * Check that the client who set the founder mode on the
2389 channel is the same client that is giving the founder
2390 mode to itself. It is done by comparing the saved public
2391 key (it is saved even in the authentication is passphrase).
2392 Affected file silcd/command.c.
2394 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Do not process packet for disconnected socket connection.
2397 Affected file lib/silccore/silcpacket.c.
2399 * Process the DISCONNECT packet through scheduler in the
2400 client library. Affected file lib/silcclient/client.c.
2402 * Fixed the silc_client_packet_parse to not to increase
2403 the packet sequence number if the conn->sock and the
2404 current socket connection is not same. This can happen
2405 for example during key agreement when the conn includes
2406 multiple socket connections (listeners). Affected file
2407 lib/silcclient/client.c.
2409 * The sender of the file transfer request now provides also
2410 the pointer (listener) for the key exchange protocol. If
2411 the listener cannot be created then it sends empty key
2412 agreement and lets the receiver provide the listener.
2414 Added `local_ip' and `local_port' arguments to the
2415 silc_client_file_send. If they are provided they are used,
2416 if not then it will attempt to find local IP address, if
2417 not found or bind fails then the remote client will provide
2420 Affected files are lib/silcclient/client_ftp.c and
2421 lib/silcclient/silcapi.h.
2423 * Extended the FILE SEND command to support defining the
2424 local IP and port for key exchange listener. They are
2425 optional. Affected file irssi/src/silc/core/silc-servers.c.
2427 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Defined to WHOIS command reply the sending of fingerprint
2430 of the client's public key (if the proof of posession of the
2431 corresponding private key is verified by the server).
2432 Updated to the protocol specification.
2434 * Added support of receiving the client's public key's
2435 fingerprint in command reply in client library. Affected
2436 file is lib/silcclient/command_reply.c, and
2437 lib/silcclient/idlist.[ch].
2439 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2441 * Do not send over 128 chars long nickname to the server
2442 in NICK command. Affected file lib/silcclient/command.c.
2444 * Do not send over 256 chars long channel names to the server
2445 in JOIN command. Affected file lib/silcclient/command.c.
2447 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2449 * Assure that silc_server_close_connection cannot be called
2450 twice for same socket context. Affected file is
2453 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2455 * Send error message to application if opening file for
2456 writing during file transfer fails. Affected file is
2457 lib/silcclient/client_ftp.c.
2459 Remove all file transfer sessions for a client that we're
2460 removing from ID cache.
2462 Affected file is lib/silcclient/client_ftp.c.
2464 * Fixed silc_net_addr2bin to return correct address. Affected
2465 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2467 * Fixed file transfer session removing on signoff notify.
2468 Affected file irssi/src/silc/core/silc-servers.c.
2470 * Added the SilcClientFileError to be returned in the monitor
2471 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2472 Affected file lib/silcclient/silcapi.h.
2474 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Fixed a crash in silc_client_ftp_free_sessions and
2477 silc_client_ftp_session_free_client. Affected file
2478 lib/silcclient/client_ftp.c.
2480 * Added `disabled' field in the SilcChannelEntry in the server
2481 to indicate if the server entry is disabled. Affected file
2482 silcd/idlist.h, silcd/command[_reply].c.
2484 * SILC server adds now /var/run/silcd.pid everytime it is
2485 started. Affected file silcd/silcd.c.
2487 * Added silc_server_packet_send_clients to send a packet to
2488 the provided table of client entries. Affected file
2489 silcd/packet_send.[ch].
2491 * Fixed a crash in client resolving in client_prvmsg.c in
2492 client library. Affected file lib/silcclient/client_prvmsg.c.
2494 * Do not actually remove the client directly from ID cache
2495 during SERVER_SIGNOFF, but invalidate it. This way we
2496 preserve the WHOWAS info for the client. Affected file
2497 silcd/server_util.c.
2499 * Fixed SERVER_SIGNOFF notify handling in the server. The
2500 server is now able to process incoming SERVER_SIGNOFF notify
2501 for a server that it doesn't even know about. It will remove
2502 the clients provided in the notify. Affected file
2503 silcd/packet_receive.c.
2505 * Check for partial packet in data queue after every packet that
2506 was found from the queue. Return and wait for more data if
2507 there is partial data in queue. Affected file is
2508 lib/silccore/silcpacket.c.
2510 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2512 * Added SilcClietFileError enum to indicate error in
2513 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2514 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2515 Affected files lib/silcclient/silcapi.h and
2516 lib/silcclient/client_ftp.c.
2518 * Check that newsize in silc_buffer_realloc is larger than
2519 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2521 * Added better monitor of file transfers. It now monitors
2522 key agreement protocol during the file transfer too. Added
2523 error reporting too. Affected files
2524 irssi/src/silc/core/silc-servers.c,
2525 irssi/src/fe-common/silc/module-formats.[ch].
2527 * Wrote a help file for FILE command.
2529 * Added silc_rng_global_get_byte_fast to get not-so-secure
2530 random data as fast as possible. Random data is read from
2531 /dev/urandom if available and from the SILC RNG if not
2532 available. It is used in padding generation. Affected file
2533 lib/silccrypt/silcrng.[ch].
2535 * All packets in client library are now processed synchronously.
2536 Optimized packet processing a lot. Affected file
2537 lib/silcclient/client.c.
2539 * All server connection packets are processing synchronously
2540 now in server, to optimize packet processing. Affected file
2543 * Include files are installed now only in Toolkit distribution
2544 if make install is given. Affected files: all Makefile.am's.
2546 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Assure that silc_client_notify_by_server_resolve does not
2549 resolve the client information multiple times. If it cannot
2550 be found by the first it cannot be found at all. Affected
2551 file lib/silcclient/client_notify.c.
2553 * Fixed WHOWAS command reply calling. Affected file
2554 lib/silcclient/command_reply.c.
2556 * Removed all references to silc_idlist_get_client from the
2557 Irssi SILC client since that call is internal call used by
2558 the library. The Irssi SILC client will use now client
2559 retrieval functions found in silcapi.h.
2561 * Fixed a bug in resolving nickname info before sending
2562 private message. It used freed memory. Affected file
2563 irssi/src/silc/core/silc-servers.c.
2565 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2567 * Assure my_channels statistics cannot go negative in server.
2568 Affected files silcd/server.c, silcd/server_util.c.
2570 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2574 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Win32 Toolkit changes. Affected files
2577 win32/silc.dsw, win32/libsilc/libsilc.def,
2578 win32/libsilcclient/libsilc.def,
2579 lib/silcutil/silcutil.c, and
2580 lib/sftp/sftp_fs_memory.c.
2582 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2584 * Added silc_net_localip to return local host's IP address.
2585 Affected file lib/silcutil/silcnet.[ch].
2587 * If key exchange or rekey protocol is active for a connection
2588 parse all packets syncronously since there might be packets
2589 in packet queue that we are not able to process without first
2590 processing packets before them. Affected file silcd/server,
2591 lib/silcclient/client.c.
2593 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2594 whether library should continue processing the packet.
2595 Affected file lib/silccore/silcpacket.h.
2597 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2598 SilcSFTPMonitorData to SFTP server to monitor various
2599 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2600 lib/silcsftp/sftp_server.c.
2602 * Added silc_file_size to return file size. Affected file
2603 lib/silcutil/silcutil.[ch].
2605 * Implemented the file transfer support for the client library.
2606 Added preliminary support for simple client to client one-file
2607 transmission. Affected file lib/silcclient/client_ftp.c,
2608 lib/silccilent/client.[ch].
2610 * Added new local command FILE to the Irssi SILC Client.
2611 It is used to perform the file transfer. It has subcommands

2619 silcd/server.c and silcd/packet_receive.c.
2621 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Renamed silc_file_read and silc_file_write to functions
2624 silc_file_readfile and silc_file_writefile. Added function
2625 silc_file_open and silc_file_close. Affected files
2626 lib/silcutil/silcutil.[ch].
2628 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2630 * Resolve the client info when received private message or
2631 channel message for a client which nickname we don't know.
2632 Affected files lib/silcclient/client_prvmsg.c and
2633 lib/silcclient/client_channel.c.
2635 * Do not crash in /KEY if client is not connected. Affected
2636 file irssi/src/silc/core/silc-channels.c.
2638 * Added SilcClientStatus field to the SilcClientEntry in the
2639 lib/silcclient/idlist.h.
2641 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2642 is incomplete and is being resolved, it won't be resolved
2645 Make sure also that USERS command reply does not resolve
2646 twice information. Affected file is
2647 lib/silcclient/command_reply.c.
2649 Make sure that silc_client_get_clients_by_list does not
2650 resolve twice same information.
2652 * Check for valid client->id in the silc_server_free_client_data.
2653 Affected file silcd/server.c.
2655 * Fixed /GETKEY nick@server not to crash if the server entry
2656 is not found. Affected file lib/silcclient/command.c.
2658 * Fixed the silc_server_check_cmode_rights to check the
2659 requested modes correctly. Affected file silcd/command.c.
2661 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Better checks for non-printable chars in nick added.
2664 Affected file silcd/command.c.
2666 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Call the silc_server_udpate_servers_by_server in the
2669 primary router that comes back online in the backup resuming
2670 protocol. Otherwise it routes packets wrong. Affected file
2671 silcd/server_util.[ch], silcd/server_backup.c.
2673 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2675 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2676 lib/silcutil/silcbuffmt.[ch].
2678 * Redefined the SILC packet header to include the padding
2679 length. Affected file lib/silccore/silcpacket.[ch].
2681 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2682 length for maximum padding up to 128 bytes). Affected
2683 file lib/silccore/silcpacket.h.
2685 * Removed all backwards support for old 0.5.x MAC thingies.
2686 The SILC packet header change makes it impossible to be
2687 backwards compatible.
2689 * Send the ENDING packet with timeout in the backup resuming
2690 protocol. This is to assure that all routers has connected
2691 to the primary router. Affected file silcd/server_backup.c.
2693 * Changed the RNG to take the first IV from random data. It
2694 used to take it from zero actually. Changed the RNG also
2695 to use /dev/urandom during session. /dev/random is used
2696 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2698 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2700 * Changed the SILC packet header to have the first two bytes
2701 (the packet length) encrypted. Affected files aroung the
2702 code tree, lib/silccore/silcpacket.[ch]. Removed the
2703 SilcPacketCheckDecrypt callback. It is not needed anymore
2704 since the silc_packet_receive_process will determine now
2705 whether the packet is normal or special.
2707 * Implemented the unidirectional MAC keys. Affected files
2708 lib/silcske/silcske.c, silcd/protocol.c and
2709 lib/silcclient/protocol.c.
2711 * Implemented the packet sequence number to the MAC computation.
2712 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2713 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2714 lib/silcclient/protocol.c.
2716 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Allow backup router to announce servers. All servers
2719 announced by backup router are added to the global list
2720 automatically. Update hte server's socket to our primary
2721 router also when backup router announces a server.
2722 Affected file silcd/packet_receive.c.
2724 * Do not update the client->router in the function
2725 silc_server_udpate_clients_by_server if the client is on
2726 global list. We might fail to find any specific server
2727 for locally connected clients and local cell clients. They
2728 should still use the `from' and not `to' as client->router.
2729 This fixes backup router resuming protocol. Affected file
2730 silcd/server_util.c.
2732 * Decrease channel statistics count only if the channel
2733 deletion worked. Affected files are silcd/server.c and
2734 silcd/server_util.c.
2736 * Added silc_server_update_servers_by_server to update origin
2737 of all server entries. Used during backup router protocol.
2738 Affected files silcd/server_util.[ch], silcd/server.c. and
2739 silcd/backup_router.c.
2741 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2742 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2743 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2744 lib/silccrypt/silchmac.c.
2746 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2748 * Assure that router cannot reroute the same channel message
2749 to the sender. Affected file silcd/packet_receive.c.
2751 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2753 * Made better checks that the channel message is not sent
2754 to the router it came from. Affected file is
2755 silcd/packet_send.c. Fixed memory leak too.
2757 * Announce informations for incoming router connection, but
2758 only after checking if it is replaced by backup router.
2759 Affected file silcd/packet_receive.c.
2761 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Fixed the backup resuming protocol to work in multiple
2764 router environment. Affected file silcd/server_backup.c.
2766 * Route packet only to one router in the function
2767 silc_server_packet_send_to_channel. Affected file is
2768 silcd/packet_send.c.
2770 * Fixed silc_server_send_notify_dest to set the broadcast
2771 flag. Fixed the silc_server_send_notify_topic to actually
2772 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2773 Affected file silcd/packet_send.c.
2775 * Changed the SFTP Filesystem interface. Changed the
2776 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2777 the filesystem operation function. The SilcSFTPFilesystem
2778 is now a context that is allocated by all filesystem allocation
2779 functions and it already includes the operations structure
2780 and filesystem specific context. It is given as argument
2781 now to the silc_sftp_server_start. This made the interface
2782 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2783 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2785 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2787 * Changed the backup router adding and getting interfaces
2788 in the server. The router that will be replaced by the
2789 specified backup router is now sent as argument. Affected
2790 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2793 * Added silc_net_addr2bin_ne to return the binary form of
2794 the IP address in network byte order. Affected files
2795 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2797 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Check for existing server ID in silc_server_new_server
2800 and in silc_server_connect_to_router_final and remove the
2801 old entry if it exists. Affected file silcd/packet_receive.c,
2804 * Send the channel message always to only one router, either
2805 in upstream or downstream. Affected file is
2806 silcd/packet_send.c.
2808 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2810 * Wrote the definition of the backup resuming protocol to the
2811 protocol specification.
2813 * Removed one redundant channel key generation from normal
2814 server during joining procedure. Removed one redundant
2815 channel key sending from server to router during joining
2816 procedure. Affected file silcd/command.c.
2818 * Made minor bugfixes to the backup router resuming protocol.
2819 Affected file silcd/server_backup.c, server.c.
2821 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Added --disable-asm configuration option. Affected files
2824 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2827 * Implemented the backup resuming protocol that is used to
2828 resume the primary router position in the cell after the
2829 primary router comes back online. Affected files
2830 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2831 and silcd/server_util.[ch].
2833 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Sleep two (2) seconds after sending QUIT command to server.
2836 Affected file lib/silcclient/command.c.
2838 * Assure that if outgoing data buffer is pending do not force
2839 send any data. Affected file silcd/packet_send.c.
2841 * Assure that if outgoing data buffer is pending do not force
2842 send any data. Affected file lib/silcclient/client.c.
2844 * Implemented the backup router support when the primary router
2845 goes down. The servers and routers can now use the backup
2846 router as new primary router without loosing connectivity.
2848 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2850 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2851 in the server to indicate disabled entry. All data read
2852 from the connection will be ignored and no data is sent
2853 for entry that is disabled. Affected files are
2854 silcd/idlist.h, silcd/server.c.
2856 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Created SFTP client and server test programs in the
2859 lib/silcsftp/tests directory.
2861 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2863 * Implemented memory filesystem (virtual filesystem) for
2864 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2867 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2869 * Implemented the SFTP (SSH File Transfer Protocol) to the
2870 lib/silcsftp. It includes SFTP client and SFTP server
2873 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2875 * Moved lib/silccore/silcprotocol.[ch] to the
2876 lib/silcutil library.
2878 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2879 take variable argument list pointer as argument. Affected
2880 file lib/silcutil/silcbuffmt.[ch].
2882 * Added silc_buffer_set function that is used to set data
2883 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2884 Affected file lib/silcutil/silcbuffer.h.
2886 * Changed various routines in the core library to use the new
2887 silc_buffer_set instead of allocating new buffer only for
2890 * Added 64-bit value formatting and unformatting support to the
2891 silc_buffer_[un]format routines. Affected file is
2892 lib/silcutil/silcbuffmt.[ch].
2894 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2895 to includes/bitmove.h.
2897 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2899 * Fixed channel user mode saving in client library. Affected
2900 file lib/silcclient/command[_reply].c.
2902 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Defined the file transfer to the SILC Protocol. Added
2905 new packet type SILC_PACKET_FTP and defined File Transfer
2906 Payload. The mandatory file transfer protocol is SFTP
2907 (SSH File Transfer Protocol). Affected file in addition
2908 of the internet draft is lib/silccore/silcpacket.h.
2910 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2911 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2912 is used as part of backup router protocol when the primary
2913 router of the cell is back online and wishes to resume
2914 the position as primary router.
2916 * Redefined the MAC generation keys in the protocol. The
2917 same key is not used anymore in both direction. Both
2918 direction will now use different keys for sending and
2919 receiving. This fixes a potential security flaw. This
2920 change causes incompatibilities in the protocol.
2922 * Redefined also the MAC computation from the packet.
2923 An packet sequence number is now added to the MAC
2924 computation. This prevents possible replay attacks against
2925 the protocol. This change too causes incompatibilities
2928 Added `sequence' field to the SilcPacketContext to hold
2929 the current sequence number for the packet.
2931 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Added `created' field to the SilcIDListData in the file
2934 silcd/idlist.h to indicate the time when the entry was
2937 * Added `created' field to the SilcChannelEntry too. Affected
2938 file silcd/idlist.h.
2940 * Added `creation_time' aguments to all the announcement functions
2941 in the server. If it is provided then only the entries that
2942 was created after the provided time frame are actually
2943 announced. Affected file silcd/server.[ch].
2945 * The protocol says that the Channel ID's IP address must be
2946 based on the router's IP address. Added check for this in
2947 the silc_server_new_channel when processing incoming New Channel
2948 Payload. Affected file silcd/packet_receive.c.
2950 * Print out the correct version with --version in SILC client.
2951 Affected file irssi/src/silc/core/silc-core.c.
2953 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * Fixed WHOWAS command to check for completnes of the client
2956 entry always, not just when the command is coming from client.
2957 Affected file silcd/command.c.
2959 * Added new function silc_server_packet_queue_purge to purge the
2960 outgoing data queue to the network. After the function returns
2961 it is guaranteed that the outgoing packet queue is empty.
2962 Affected file silcd/packet_send.[ch].
2964 * Purge the outgoing packet queue in the rekey protocol's final
2965 callback to assure that all rekey packets go to the network
2966 before quitting the protocol. Affected file silcd/server.c.
2968 * Added silc_client_packet_queue_parse as similar function as
2969 in server to the client library. The affected file is
2970 lib/silcclient/client.c.
2972 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * Splitted silcd/server.c and created silcd/server_util.[ch]
2975 for utility functions.
2977 * Added new socket flag SILC_SF_DISABLED to indicate that the
2978 connection is open but nothing can be sent to or received from
2979 the connection. Affected file lib/silcutil/silsockconn.[ch].
2980 The checking for disabled socket is checked in the low level
2981 silc_socket_write and silc_socket_read functions.
2983 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Allow only nicknames and channel names that fits into the
2986 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2988 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2990 * When processing JOIN command reply in server check that if
2991 the channel exists in our global list we'll move it the local
2992 list. Affected file silcd/command_reply.c.
2994 * Fixed the check whether client is joined on the channel already
2995 in JOIN command. Affected file lib/silcclient/command.c.
2997 * Fixed the JOIN command reply to check whether the channel
2998 already exists. Affected file lib/silcclient/command_reply.c.
3000 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3002 * Added silc_ske_status_string to map the SKE error numbers
3003 to readable strings. The affected files are
3004 lib/silcske/silcske[_status].[ch].
3006 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Do not show the private channels on the WHOIS channel list
3009 as it is not allowed by the protocol. The affected file is
3012 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Assure that the packet length digged from the actual packet
3015 is something sensible in the silc_packet_decrypt_rest_special
3016 in lib/silccrypt/silcpacket.c.
3018 * Free and NULL the allocated pointer in silc_hmac_alloc if
3019 the HMAC allocation fails. The affected file is
3020 lib/silccrypt/silchmac.c.
3022 * Print the selected security properties to the log files in
3023 the server. Affected file silcd/protocol.c.
3025 * Add SKE's reference counter even if calling the completion
3026 callback manually. Otherwise it goes negative, although it
3027 does not cause any problems. The affected file is
3028 lib/silcske/silcske.c.
3030 * Remove the client entry with short timeout after giving the
3031 KILL command. Affected file lib/silcclient/command.c.
3033 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3034 case all found clients are already disconnected (WHOWAS would
3035 found them) in the server. Affected file silcd/command.c.
3037 * Update the last_receive (time of last data received) to be
3038 updated only when received private or channel message so that
3039 the idle time showed in WHOIS makes more sense.
3041 * Added boolean field `valid' in to the SilcClientEntry in the
3042 client library to indicate whether the entry is valid or not.
3043 This fixes the nickname change bug on channel when changing
3044 the nickname to be same than the old (like nick to Nick) the
3045 nickname formatter doesn't set the new nick anymore to Nick@host.
3046 Affected file lib/silcclient/idlist.[ch].
3048 * Now actually fixed the nickname changing on disconnection.
3049 Added new function silc_change_nick to the Irssi SILC Client.
3050 Affected file irssi/src/silc/core/client_ops.c,
3051 irssi/src/silc/core/silc-nicklist.[ch].
3053 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Check that the public key exists in the GETKEY command before
3056 trying to encode it. Affected file silcd/command.c.
3058 * Print some notifications on received public keys with GETKEY
3059 command in the Irssi SILC Client. Affected files are
3060 irssi/src/fe-common/silc/module-formats.[ch],
3061 irssi/src/silc/core/client_ops.c.
3063 * Use IDENTIFY command to resolve the server information in the
3064 GETKEY command instead of INFO command. Affected file
3065 lib/silcclient/command.c.
3067 * All command reply functions in the client library now calls
3068 the pending command reply callbacks even if an error has
3069 occurred. The server has done this a long time and now it was
3070 time to move the client library to this as well. Now all
3071 errors can be delivered back to the pending command reply
3072 callbacks if necessary. Affected files are
3073 lib/silcclient/command[_reply].[ch].
3075 * Change the nickname on disconnection back to the username
3076 because in reconnect the server will enforce it to it anyway.
3077 Affected file irssi/src/silc/core/silc-servers.c.
3079 * Fixed a config file parsing bug in the Irssi SILC client.
3080 Affected file irssi/src/silc/core/clientconfig.c.
3082 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * When printing the channel mode on JOIN, verify that the
3085 channel key and channel's HMAC are valid. Affected file
3086 irssi/src/silc/core/client_ops.c.
3088 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3090 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3091 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3092 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3094 * Removed channel key rekey task deleting from the function
3095 silc_server_save_channel_key. Affected file silcd/server.c.
3096 Added explicit timeout task context instead that is used to
3097 delete the task if we are registering a new task before the
3098 new task has elapsed.
3100 * When channel key rekey occurs the client library now saves
3101 the old channel key for a short period of time (10 seconds) and
3102 is able to use it in case some is still sending channel
3103 messages encrypted with the old key after the rekey. Affected
3104 file lib/silcclient/[idlist.h|client_channel.c].
3106 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3108 * Added check to the silc_server_new_id_real to not accept
3109 new ID if it is the sender's own ID. Affected file is
3110 silcd/packet_receive.c.
3112 * Assure that we do not announce ourself or the one we've
3113 sending our announcements when we're router and are announcing
3114 servers to our primary router. Affected file silcd/server.c.
3116 * Fixed silc_server_command_identify_check_client to assemble
3117 correct WHOIS packet. It send corrupted WHOIS packet and
3118 caused problem with router to router connections. Affected
3119 file silcd/command.c.
3121 Fixed also silc_server_command_whois_check the same way
3122 as for the IDENTIFY command.
3124 * Added new SilcIDListStatus to the server in the SilcIDListData
3125 structure. The status now includes the current status of
3126 the entry (like registered, resolved etc.). Affected file
3127 silcd/idlist.[ch]. Defined a bunch of different status types
3128 as well. This replaced the old boolean registered field as well.
3130 Added resolve_cmd_ident field to the SilcClientEntry structure
3131 too so that if the entry is for example being resolved so
3132 another command may attach to the same pending command reply
3133 without requiring to resolve the same entry again. This concept
3134 should optimize the WHOIS and the IDENTIFY resolving under
3135 heavy load by taking away unnecessary resolving for entries
3136 that are being resolved already.
3138 Added support for adding multiple pending commands for one
3139 command idenfier. Affected file silcd/command[_reply].[ch].
3141 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3142 before deleting the data. Otherwise the hash table will have
3143 freed data in comparison functions. Affected file is
3144 silcd/command_reply.c.
3146 * Fixed silc_idlist_replace_client_id to add the new entry to
3147 the cache with NULL nickname. Otherwise there will be invalid
3148 memory as the nickname after the nickname is freed. Affected
3149 file silcd/packet_receive.c.
3151 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3152 saved into wrong slots because the previous number of entries
3153 was not taken into account. Affected file silcd/idlist.c.
3154 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3156 * If we are router and we receive JOIN notify to a channel that
3157 does not have any users then notified client is marked as the
3158 channel founder, as it is it. The affected file is
3159 silcd/packet_receive.c
3161 * Added to the extended hash table API's table_del_*ext functions
3162 the destructor as argument too, so that the caller can decide
3163 which destructor to use or whether to use destructor at all.
3164 Affected file lib/silcutil/silchashtable.[ch].
3166 * Fixed ID Cache purging. It actually deleted the entries from
3167 the hash table after the data was freed. The hash table ended
3168 up comparing freed memory. The affected file is
3169 lib/silccore/silcidcache.c.
3171 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3173 * Fixed Irssi SILC client's KILL command's HELP syntax.
3175 * The USERS command now resolves the detailed user information
3176 if the userinfo field is missing. Affected file is
3177 lib/silcclient/command_reply.c.
3179 * Do not print error in silc_file_read if the read file does
3180 not exist. Just silently return NULL. Affected file is
3181 lib/silcutil/silcutil.c.
3183 * Fixed the silc_log_output to not wine about NULL filename
3184 and to not create some bogus " " filename. Affected file is
3185 lib/silcutil/silclog.c.
3187 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Fixed various printing bugs on the user interface in the
3190 Irssi SILC Client. Minor changes that were forgotten from
3193 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3195 * Fixed the configure.in.pre and the compilation and distribution
3196 environment to support the new autoconf 2.52. That version is
3197 now required to compile the CVS trunk.
3199 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3201 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3202 to generally parse user@fqdn format strings. Affected file
3203 lib/silcutil/silcutil.c.
3205 * Added nickname_format and nickname_force_format fields to the
3206 SilcClientParams structure. The first one defines the format
3207 for the nicknames that the library will enforce if the receives
3208 multiple same nicknames. The second one is boolean value and
3209 can be used to force the library to always enforce the format
3210 to the nicknames regardles whether there are multiple nicknames
3211 or not. This configurable formatting was employed to flexibly
3212 support accessing multiple nicknames from the user interface.
3213 The userinterface can now set the nicknames to what ever format
3214 they prefer. Affected file lib/silcclient/silcapi.h.
3216 Added function silc_client_nickname_format to the file
3217 lib/silcclient/idlist.c. It performs the nickname formatting.
3219 Added new field `hostname´ to the SilcClientEntry context.
3220 It holds the hostname of the client. Affected file is
3221 lib/silcclient/idlist.h.
3223 * Irssi SILC Client sets the nicknames in nick@hostn format.
3224 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3225 irssi/src/silc/core/silc-core.c.
3227 The WHOIS printing now also shows both the real nickname and
3228 the formatted nickname so that user knows how to access the
3229 user if there are multiple same nicknames cached. Affected
3230 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3231 printing formatting too to take the hostname now as a separate
3232 argument. The Affected file is
3233 irssi/src/fe-common/silc/modules-formats.[ch].
3235 * Changed the silc_client_get_clients_local to accept the formatted
3236 nickname as argument. It accepts the real nickname too but the
3237 formatted nickname can be used to find the true entry from
3238 multiple entries. Affected file lib/silcclient/silcapi.h and
3239 lib/silcclient/idlist.c.
3241 * Added nickname_format_parse field to the SilcClientParams.
3242 It is a callback function provided by the application to parse
3243 the nickname out of the formatted nickname string. The library
3244 calls it to get the nickname from the formatted string. Since
3245 the application generally knows better the format of the nickname
3246 string it parses it instead of the library, even though library
3247 encodes the formatted string. If the callback function is not
3248 provided then the library will use the string as is. The
3249 affected file is lib/silcclient/silcapi.h.
3251 * All the nickname strings passed to the client library in
3252 commands are now expected to be formatted nickname strings.
3253 If the command does not support the formatted nickname string
3254 it will assume that the sent string is the actual nickname.
3255 Affected file lib/silcclient/command.c.
3257 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * Added public key authentication support to OPER and SILCOPER
3260 commands in the client library. Affected file is
3261 lib/silcclient/command.c.
3263 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3265 * Changed the get_auth_methdod client operation to be asynchronous.
3266 It can be async if the application resolves the authentication
3267 method from the server during the negotiation. Added new
3268 SilcGetAuthMeth completion callback that the application will
3269 call after resolving the authentication method.
3271 Added function silc_client_request_authentication_method that
3272 the application can use to resolve the authentication method
3273 from the server. Added also SilcConnectionAuthRequest callback
3274 that the library will call after the server has replied. The
3275 application can call this function if it does not know the
3276 current authentication method.
3278 Affected files are lib/silcclient/client.c and
3279 lib/silcclient/silcapi.h.
3281 * The Irssi SILC client now automatically resolves the authentication
3282 method incase any configuration information is not present (and
3283 currently there never is). The affected file is
3284 irssi/src/silc/core/client_ops.c.
3286 * Fixed public key authentication from the client library.
3287 Affected file lib/silcclient/protocol.c. Changed also the
3288 protocol specification about the public key authentication in
3289 the connection authentication protocol. The actual data to be
3290 signed is now computed with a hash function before signing.
3292 * Fixed the public key authentication from the server as well.
3293 Affected file silcd/protocol.c.
3295 * Removed the mlock()'s from the memory allocation routines.
3296 Affected file lib/silcutil/silcmemory.c. The ./configure does
3297 not check anymore for the mlock(). Affected file is
3300 * Fixed USERS command in server to allow the execution of the
3301 command for private and secret channels if the client sending
3302 the command is on the channel. Affected file silcd/command.c.
3304 * Fixed silc_client_get_clients_local to return the clients
3305 count correctly. It could return wrong value. Affected file
3306 lib/silcclient/idlist.c.
3308 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3310 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3311 types. The assembler optimizations seemed not to like 64-bit
3312 data types. The assmebler optimizations thus are now enabled
3313 also for BSD systems as opposed to only enable them for Linux.
3315 * Do not check for threads at all on BSD systems. Affected
3316 file configure.in.pre.
3318 * Removed -n and -h options from the Irssi SILC Client since
3319 they are not used in silc.
3321 * Fixed the prime generation to assure that the first digit
3322 of the generated random number is not zero since our conversion
3323 routines does not like number strings that starts with zero
3324 digit. If zero digit is seen the random number is regenerated.
3325 This caused some corrupted RSA keys when the zero first digit
3326 was met. Affected file lib/silcmath/silcprimegen.c.
3328 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Fixed WIN32 configuration in the ./configure script.
3331 Fixed to include xti.h on environments that has it.
3332 Patches by Carsten Ilchmann and andrew.
3334 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Changed the silc_id_create_client_id to be collision
3337 resistant. It is now assured that there cannot be created
3338 two same client ID's. I suspect that some weird bugs in
3339 the server were actually caused by duplicate Client IDs.
3340 Affected file silcd/serverid.[ch]. A router receiving
3341 new ID now also assures and informs the sending server
3342 if the ID caused collision.
3344 * Changed the silc_id_create_channel_id to also assure that
3345 there are no collisions.
3347 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Statement about ignoring the Mutual Authentication flag when
3350 performing rekey with PFS was a bit misleading. It is ignored
3351 if it was set in the initial negotiation, it cannot be even
3352 set in the rekey. Fixed in the ke-auth draft. Started the
3353 new versions of the protocol drafts in the doc/.
3355 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3357 * Fixed a bug in silc_client_command_identify_save when saving
3358 new channel information. The channel name was no duplicated
3359 and caused crash on exit. Affected file is
3360 lib/silcclient/command_reply.c.
3362 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3364 * Fixed the getkey command handling in the server. Send just
3365 empty OK reply to the sender if the key could not be fetched
3366 (but everything else was ok, like the key just was not available).
3367 Changed the public key parameter to optional in the protocol
3368 specs so that empty OK reply can be sent. Affected file
3371 Added a message to Irssi SILC client to tell to user if the
3372 server did not return a public key.
3374 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3376 * Fixed a channel key regeneration bug. It registered new
3377 timeout tasks exponentially until all system resources were
3378 used. Affected file silcd/server.c.
3380 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Added the SILC Document generator to the scripts/silcdoc.
3383 It can be used to generate the Toolkit Reference Manual out
3384 of the source tree. Internally it will also use the RoboDoc
3385 generator now imported in util/robodoc.
3387 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * Added couple of return's in rekey protocol if error orccurred
3390 during the protocol. The execution must be terminated.
3391 Affected file silcd/protocol.c. Also, terminate the protocol
3392 always with timeout.
3394 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3396 * The client's Client ID was created initally from the wrong
3397 nickname (it could have been in format nick@host) in the
3398 silc_server_new_client. Affected file silcd/packet_receive.c
3400 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3402 * Added some SILC_LOG_ERROR's to various error conditions
3403 if client could not be added to ID cache. Affected files
3404 silcd/packet_receive.c and silcd/server.c.
3406 * When client's sock->user_data is freed, NULL also the
3407 client->router and client->connection pointers. Added check
3408 for these pointers being NULL to various places around the
3409 code. Affected file silcd/server.c.
3411 * Added client->data.registered == TRUE checks to various
3412 places around the code to assure that unregistered client's
3413 are not handled when it is not allowed. Affected file
3416 * Added `bool registered' fields to all
3417 silc_idlist_[server|client]_get_* routines to indicate whether
3418 the fetched client needs to be registered or not. Affected
3419 file silcd/idlist.[ch].
3421 * Add your own entry as registered to the ID cache in the
3422 server. Affected file server.c.
3424 * Fixed a bug in silc_server_new_server. The SilcServer was
3425 set as the new server's context instead of SilcServerEntry.
3426 This naturally caused some weird bugs.
3428 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3430 * Do not delete the channel rekey task when adding it
3431 for in silc_server_create_channel_key.
3433 * Changed the silc_server_create_channel_key to return
3434 TRUE or FALSE to indicate the success of the channel key
3437 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3439 * Fixed MSVC++ project files and added missing files to
3440 Makefiles under win32/.
3442 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3444 * Do not add TCP_NODELAY flag if the operating system
3445 does not have it defined. Affected files are
3446 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3448 * Fixed buffer overflow from Irssi SILC Client. Affected
3449 file irssi/src/fe-common/core/themes.c.
3451 * Fixed double free in client library in the file
3452 lib/silcclient/client.c when disconnecting from server.
3454 * Applied double free patch from cras to Irssi SILC client.
3455 Affected files irssi/src/core/[modules/expandos].c
3457 * Fixed the disconnection handling to Irssi SILC Client.
3458 The application must call silc_client_close_connection
3459 in ops->connect client operation in case of failure of
3460 the connection. Affected file is
3461 irssi/src/silc/core/client_ops.c.
3463 * Do not set sock->protocol to NULL in the function
3464 silc_client_close_connection after executing the protocol's
3465 final callback since the sock might not be valid anymore.
3466 Affected file lib/silcclient/client.c.
3468 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3470 * Do not enable SILC_THREADS if the linking with libpthread
3471 did not happen. Affected file configure.in.pre.
3473 * Added notion to protocol specification that server must
3474 verify the sent authentication payload with CMODE when
3475 setting the channel founder key. Implemented it to the
3476 server. Affected file silcd/command.c.
3478 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Added _EXTRA_DIST SILC distribution variable to the
3481 distributions file. It is used to conditionally add extra
3482 files or directories to the specific distribution. Affected
3483 files ./prepare, Makefile.am.pre and distributions.
3485 Removed the `_' from the start of the distribution names.
3488 * Added README.WIN32 for instructions to compile the Toolkit
3491 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Fixed a double free in disconnection in the server. Affected
3494 file is silcd/server.c.
3496 * Fixed the lib/silcske/groups.c to work now also with GMP
3497 MP library. The string conversion did not work when using
3498 specific base and the base is indicated in the string as well.
3500 * Created win32/ directory which now includes MSVC++ specific
3501 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3502 It will appear only in the toolkit distribution
3504 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3506 * Changed the key material distribution function in case when
3507 the hash output is too short. The data is now concatenated
3508 a bit differently than it used to. Made the change to the
3509 SKE protocol specification.
3511 * Added better GMP detection to configure.in.pre. A patch
3514 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Fixed a minor bug in SKE that might cause some problem on
3517 some platforms. Affected file lib/silcske/silcske.c.
3519 * Added the cookie checking for initiator in the SKE. It checks
3520 that the responder returns the sent cookie unmodified. The
3521 affected file is lib/silcske/silcske.c. Added new SKE
3522 error type INVALID_COOKIE that can be sent during the
3523 negotiation. Fixed some memory leaks as well.
3525 * Added the "invalid cookie" error message to Irssi SILC client's
3528 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3530 * Added `task_max' field to the SilcClientParams to indicate
3531 the maximum tasks the scheduler can handle. If set to zero,
3532 default values are used. Affected file lib/silcclient/silcapi.h.
3534 * Fixed memory leaks in silc_client_close_connection. Affected
3535 file lib/silcclient/client.c.
3537 * Added silc_client_del_client_entry to client library to free
3538 all memory of given client entry. Affected file is
3539 lib/silcclient/idlist.[ch].
3541 * Added new functions silc_client_del_channel and
3542 silc_client_del_server to delete channel and server entries.
3543 Affected file lib/silcclient/[silcapi.h/idlist.c].
3545 * Removed silc_client_del_client_by_id from silcapi.h.
3547 * Fixed the INFO command to return the server's own info
3548 correctly when querying by Server ID. Affected file is
3551 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Removed the non-blocking settings in WIN32 code in the
3554 silc_sock_[read/write] and added SleepEx instead. Affected
3555 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3556 of input data is now checked with FIONREAD and ioctlsocket.
3558 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Call silc_schedule_task_del_by_context in the
3561 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3562 Affected file lib/silccore/silcprotocol.c.
3564 * Call silc_protocol_cancel for active protocols in the
3565 silc_server_close_connection if the funtion
3566 silc_server_free_sock_user_data has not been called.
3567 Affected file silcd/server.c.
3569 * Generic tasks cannot be deleted using the del_by_fd
3570 task deleting function since generic tasks does not match
3571 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3573 * Added a notion to SILCOPER help file that the SILCOPER works
3574 only on router server, not on normal server.
3576 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Added for WIN32 support for the new scheduler as well.
3579 Affected file lib/silcutil/win32/silcwin32schedule.c.
3581 * Fixed the SHA1 implementation to work on various platforms.
3583 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3585 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3586 API. It is part of the scheduler now. Everything else is
3587 as previously but some functions has changed their names.
3588 Checkout the lib/silcutil/silcschedule.h for the interface.
3589 Updated all applications to use the new interface. Affected
3590 files are lib/silcutil/silcschedule.[ch].
3592 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Found a bug in the SKE implementation. The HASH value,
3595 specified by the protocol, was not computed correctly. The
3596 public key of the responder was not added to the computation
3597 even though it is mandatory. Affected file lib/silcske/silcske.c.
3598 This unfortunately causes incompatibilities with older
3599 clients and servers.
3601 * Added WIN32 specific network init and uninit functions:
3602 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3603 the Winsock2. Affected file lib/silcutil/silcnet.h and
3604 lib/silcutil/win32/silcwin32net.c.
3606 * Set the socket always to nonblocking mode on WIN32 after
3607 reading data or writing data. Affected file is
3608 lib/silcutil/win32/silcwin32sockconn.c.
3610 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Fixed various compilation problems under WIN32. Affected
3613 files lib/silcutil/win32/silcwin32thread.c and
3614 lib/silcutil/win32/silcwin32schedule.c.
3616 * Removed all _internal.h #includes from public header
3617 files. Internal headers must never be included from
3620 Removed also the lib/silcske/payload_internal.h file.
3622 * All include files that may be needed (public and some others
3623 included by the public headers) by application developers are
3624 now copied to the ./includes directory. It does not copy any
3625 internal headers. Affected file Makefile.defines.pre and all
3626 Makefile.am's under lib/ and subdirs.
3628 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3630 * Do not change the ~/.silc directory's permissions automatically.
3631 Affected file irssi/src/silc/core/clientutil.c.
3633 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3635 * Do not cancel the protocol in silc_server_close_connection
3636 it might cause recursion. Now cancelled in the function
3637 silc_server_free_sock_user_data. Affected file silcd/server.c.
3639 * Fixed the silc_server_remove_clients_by_server to regenerate
3640 the channel keys correctly finally. Added also new function
3641 silc_server_remove_clients_channels to actually do it.
3642 Affected file silcd/server.c.
3644 * Fixed the silc_server_new_channel to not crash by giving
3645 wrong router to the new channel. Affected file is
3646 silcd/packet_receive.c.
3648 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3650 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3651 which is given as argument to the silc_client_alloc now.
3652 It can be used to configure the client and set various parameters
3653 that affect the function of the client.
3655 * The USERS command in server did not check whether the channel
3656 is private or secret. Affected file silcd/command.c.
3658 * Added new argument to the USERS command in protocol specification.
3659 The USERS command now can take the channel name as argument
3660 as well. Added support for this in client and server and
3661 updated the protocol specs.
3663 * Completed the GETKEY command in client. It can be now used
3664 to fetch also servers public key not only some clients.
3665 Affected files lib/silcclient/command[_reply].c.
3667 * Added silc_client_get_server to return server entry by the
3668 server name. Affected files lib/silcclient/silcapi.h and
3671 * Redefined the IDENTIFY command in protocol specification to be
3672 more generic. It now can be used to query information about
3673 any entity in the SILC Network, including clients, servers and
3674 channels. The query may be based either the entity's name
3675 or the ID. Added support for this in both client and server.
3677 Affected files silcd/command.c and lib/silcclient/command.c
3678 and command_reply.c.
3680 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3681 the _from_client and _from_server functions. Affected file
3684 * Added silc_client_get_channel_by_id_resolve to the file
3685 lib/silcclient/silcapi.h to resolve channel information by
3686 its ID. Added also silc_client_get_channel_by_id that
3687 does not resolve it from the server.
3689 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Added SilcServerEntry context into the client library
3692 to represent one server. The INFO command now allocates
3693 these to save the resolved server info. For now on the
3694 client library will also keep information about servers,
3695 connected and resolved with INFO.
3697 The INFO command now allocates the SilcServerEntry context
3698 and saves the server info there. The COMMAND_REPLY in
3699 the INFO now returns the parameters to application in
3700 same order as defined in the protocol specification.
3702 The entries are cached in the client->server_cache.
3704 * The INFO command is now issued after received the Client ID
3705 from the server. Affected file lib/silcclient/client.c.
3707 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3708 to the application as the mode changer might be server.
3709 It is guaranteed that NULL is not returned anymore to the
3710 application. Affected file lib/silcclient/client_notify.c.
3712 The ID Type is now also passed to the application so that
3713 it can check whether the returned entry is SilcClientEntry
3716 Added new function silc_client_get_server_by_id to return
3717 the server entry by ID. Affected files are the
3718 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3720 * Do not create the channel in the Irssi SILC Client when issuing
3721 the JOIN command but when received the sucessful JOIN command
3722 reply. Otherwise the channel might get created even though we
3723 could not join it. The Affected file is
3724 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3726 * Fixed a channel joining bug in router. The router must also
3727 check the channel modes, invite and ban lists etc. when serving
3728 the JOIN command sent by normal server. Affected file is
3729 silcd/command.c. The router now resolves the client's
3730 information from the server who sent the JOIN command if it
3731 does not know it, and processes the JOIN command only after
3734 * Changed the SilcCommandCb to take new argument; void *context2.
3735 Affected file lib/silccore/silccommand.h
3737 The second argument in the command callbacks in the server now
3738 includes the SilcServerCommandReplyContext if the command was
3739 called as pending command callback from the command reply.
3740 Otherwise it is NULL. When called as pending the status of the
3741 command reply will be checked and if it was erronous the
3742 error will be sent to the original sender of the command.
3743 This way the client always receives the error messages even
3744 though the server was actually the one who received the error
3745 when it resent the command to router, for example. Affected
3746 files silcd/command[_reply].[ch].
3748 * Fixed sending WHOWAS command's error message to client if
3749 the requested client could not be found. It was missing.
3752 * Changed the CMODE and CUMODE commands reply arguments in the
3753 protocol specification. The Channel ID is now sent in both
3754 of the commands to identify the channel. Implemented this
3755 new feature to the client and server. Affected files
3756 lib/silcclient/command_reply.c and silcd/command.c.
3758 * Made better checks for invite and ban lists in the JOIN
3759 command in server. Affected file silcd/command.c.
3761 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * The server now performs the incoming host IP/DNS lookup
3764 using the silc_socket_host_lookup and thus does not block
3765 the server anymore. Affected file silcd/server.c.
3767 * Completed the multi-thread support for SILC Scheduler in
3768 the lib/silcutil/silcschedule.c.
3770 * Fixed the configure.in.pre to detect the pthread correctly
3773 * Fixed a deadlock in silc_task_queue_wakeup in the file
3774 lib/silcutil/silctask.c.
3776 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Added new function silc_schedule_wakeup that is used in
3779 multi-threaded environment to wakeup the main thread's
3780 schduler. It needs to be used when a thread adds a new task
3781 or removes a task from task queues. After waking up, the
3782 scheduler will detect the task queue changes. If threads
3783 support is not compiled in this function has no effect.
3784 Implemented the wakeup mechanism to both Unix and WIN32
3785 systems. Affected files are lib/silcutil/silcschedule.[ch],
3786 lib/silcutil/unix/silcunixschedule.c and the
3787 lib/silcutil/win32/silcwin32schedule.c.
3789 * Added new function silc_task_queue_wakeup to wakeup the
3790 scheduler by the specified task queue. Affected file
3791 lib/silcutil/silctask.[ch].
3793 * The silc_socket_host_lookup_start now wakes up the scheduler
3794 after adding the timeout task. Affected file is
3795 lib/silcutil/silcsockconn.c.
3797 * The silc_socket_host_lookup is synchronous now if the threads
3798 support is not compiled in. However, the callback is still
3799 called asyncronously through the scheduler, anyway. Affected
3800 file lib/silcutil/silcsockconn.c.
3802 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3804 * Added new function silc_socket_host_lookup to perform
3805 asynchronous IP and FQDN lookups for the socket connection.
3806 Affected files lib/silcutil/silcsockconn.[ch].
3808 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3810 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3811 that may or may not compile the mutex support in.
3813 Changed the silc_mutex_alloc interface. It allocates the
3814 mutex now to the sent pointer and returns TRUE or FALSE.
3816 Affected file lib/silcutil/silcmutex.h.
3818 * Wrote the SILC Task Queue interface to support multi-threads.
3819 Affected file lib/silcutil/silctask.[ch].
3821 * Wrote the SILC Scheduler to support multi-threads. Affected
3822 file lib/silcutil/silcschedule.c.
3824 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3826 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3827 in lib/silcutil/win32/.
3829 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Defined SILC Mutex API and SILC Thread API and implemented
3832 them for Unix. Affected files are
3833 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3834 lib/silcutil/unix/silcunixmutex.c and
3835 lib/silcutil/unix/silcunixthread.c.
3837 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3839 * Fixed the silc_server_remove_clients_by_server's channel
3840 key re-generation. The hash table handling was incorrect
3841 and would not work with many channels. Affected file is
3844 * Fixed some memory leaks around the server code.
3846 * Rewrote the silc_server_get_users_on_channel to support IPv6
3847 based Client ID's. Affected file silcd/server.c.
3849 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3850 specification. However, a separate document must be written
3851 to define the detailed signing procedure and the payload
3852 associated with the flag. Defined the flag to the
3853 lib/silccore/silcchannel.h as well.
3855 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3857 * Changed the dynamic tables to static size tables in the
3858 lib/silccrypt/silchmac.c.
3860 * Removed GCC dependencies from the code. A patch by cras.
3862 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3864 * Do not show the error "Error receiving packet bla bla"
3865 in server if it really was not an error (-2 means that reading
3866 is pending). Affected file silcd/server.c.
3868 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3870 * Fixed a possible crash in silc_server_remove_clients_by_server
3871 in silcd/server.c. Fixed there also some memory leaks.
3873 * Fixed the silc_idlist_replace_client_id. It could replace
3874 wrong key in the hash table. Affected file silcd/idlist.c.
3876 * Do not check whether there are global users on the channel
3877 if the channel->global_users is FALSE. Affected functions
3878 silc_server_remove_from_one_channel and
3879 silc_server_remove_from_channels in silcd/server.c. Also,
3880 do not check if the removed client is local as we can be
3881 sure that global client was not removed from the channel
3882 and checking for global users is not needed.
3884 * The silc_server_remove_clients_by_server now re-generates
3885 the channel keys correctly for those channels that had
3886 clients removed from them. Affected file silcd/server.c.
3888 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3890 * Found the reason of random crashes in the server. We weren't
3891 ignoring the SIGPIPE signal (which can be sent in write())
3892 and it crashed the server. Affected file silcd/silcd.c.
3894 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3896 * Assure that sock->user_data is not NULL in the function
3897 silc_server_packet_send in silcd/packet_send.c.
3899 * Disconnect the remote connection if it could not be added
3900 to any ID lists in the server. The affected file is
3903 * Check in silc_server_packet_send[_real/dest] that the
3904 socket is not disconnecting and ignore the data if it is.
3905 Affected file silcd/packet_send.c.
3907 * Define inline to __inline on native WIN32 compilation.
3908 Affected file includes/silcwin32.h.
3910 * Added some explicit type casts for inline code since MSVC
3911 require them. Affected files lib/silcutil/silcbuffer.h,
3912 lib/trq/silcdlist.h and lib/trq/silclist.h.
3914 * Print warning in log files from now on if the packet
3915 decryption fails. Affected file silcd/server.c.
3917 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Changed the `say' client operation's interface to accept
3920 new `type' argument to indicate the type of the message sent
3921 by the library. The application may filter the library's
3922 messages according the type. The affected file is the
3923 lib/silcclient/silcapi.h.
3925 * Added two new functions to lib/silcclient/silcapi.h:
3926 silc_client_del_client and silc_client_del_client_by_id.
3927 Affected file lib/silcclient/idlist.c.
3929 * Moved the clientincludes.h from includes/ to silc/ and
3930 serverincludes.h from includes/ to silcd/.
3932 * The modes for the CMODE and CUMODE are now passed as
3933 uint32 for application with COMMAND_REPLY. The affected
3934 file is lib/silcclient/command_reply.c.
3936 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * /WHOIS without arguments shows client's own information.
3939 Affected file lib/silcclient/command.c.
3941 * Changed PING to not accept any arguments. The specs
3942 says that client can ping only the connected server so
3943 requiring an argument is not needed. Affected file is
3944 lib/silcclient/command.c.
3946 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Fixed a fatal bug in private message sending and reception
3949 encryption and decryption when using private message keys.
3950 The implementation was incorrect and did not follow the
3951 specification. It causd that some of the message were
3952 lost since it did not use the sending and receiving keys
3953 as the protocol suggests. This has been fixed and will cause
3954 incompatibilities with older clients when sending private
3955 message encrypted with private message keys. Affected files
3956 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3957 and various other in Irssi SILC Client.
3959 Added `responder' boolean argument to the functions
3960 silc_client_add_private_message_key[_ske] to indicate when
3961 the key is added as responder or initiator of the key
3964 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Removed the silc_ske_check_version function and created
3967 a SilcSKECheckVersion callback. Added also a function
3968 silc_ske_set_callbacks that is now used to set all SKE
3969 callbacks. The callback functions are not given to
3970 the SKE functions anymore, but this function is used to
3973 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3975 * Added `silc_version' argument to the silc_client_alloc
3976 to define the version of the application for the library.
3977 The library will use the version string to compare it
3978 against the remote host's (usually a server) version
3979 string. Affected file lib/silcclient/silcapi.h
3981 * Added the KE protocol context to Key Agreement context
3982 in client library so that we can abort the SKE if it
3983 is in process when we get timeout. Affected file is
3984 lib/silcclient/client_keyagr.c.
3986 * Do not resolve the client ID forever if it returns in the
3987 first time that such client does not exist. This was done
3988 for example with private message. Affected file is
3989 lib/silcclient/client_prvmsg.c.
3991 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3993 * Do not add regex.h for WIN32. The affected file
3994 includes/silcincludes.h.
3996 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3997 not work yet 100%. It generates the DLL's automatically
3998 when compiling with --with-win32 under cygwin.
4000 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * lib/contrib/regex.c is not compiled on WIN32.
4004 * Added silc_net_get_socket_opt function to the
4005 lib/silcutil/silcnet.h.
4007 * Added includes/silcwin32.h for WIN32 specific includes
4010 * Do not use ptime structure or any of the posix process
4011 functions on WIN32 in lib/silccrypt/silrng.c.
4013 * Added silc_gettimeofday to provide generic function
4014 for struct timeval on all platforms. Added the function
4015 to lib/silcutil/silcutil.h.
4017 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4019 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4020 library as they clearly belong there. As a plus side we
4021 can make the actual socket connection routines platform
4024 Added also new generic function silc_socket_read and
4025 silc_socket_write (that used to be silc_packet_[read/write].
4026 The implementation of these are platform specific.
4028 * Added WIN32 specific routines of silc_socket_[read/write]
4029 to lib/silcutil/win32/silcwin32sockconn.c.
4031 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4033 * Added preliminary support for native WIN32 compilation under
4034 cygwin (using the -mno-cygwin option for GCC) to the
4035 ./configure.in.pre. The --with-win32 now prepares the
4036 compilation for native WIN32.
4038 * Rewrote the SILC Scheduler interface in the file
4039 lib/silcutil/silcschedule.h. The scheduler is now context
4040 based and does not have anymore any global static scheduler.
4041 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4042 and created lib/silcutil/win32 directory for WIN32 based
4045 * Added Unix specific network routines to the
4046 lib/silcutil/unix/silcunixnet.c and the old
4047 lib/silcutil/silcnet.c includes now only generic routines.
4049 Added WIN32 specific network routines to the
4050 lib/silcutil/win32/silcwin32net.c.
4052 * Added Unix specific utility functions from the
4053 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4055 * Added WIN32 SILC Scheduler to the file
4056 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4059 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Do not handle JOIN notify in the server if the target client
4062 is not registered (idata->registered == FALSE). The affected
4063 file is silcd/packet_receive.c.
4065 * Update the nickrec->founder in event_cumode in the Irssi SILC
4066 client. Affected file irssi/src/silc/core/silc-channels.c.
4068 * Fixed the CUMODE_CHANGE notify handling in the server when
4069 server and router are announcing their clients on channels.
4070 Now the mode changes are saved and notified correctly. The
4071 affected file is /silcd/packet_receive.c.
4073 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4074 They really did not replace the cache entry in the ID Cache.
4075 Now they do that. Affected file silcd/idlist.c.
4077 * Fixed the KICK notify handling in the Irssi SILC client to
4078 update the channel records so that the kicked client does not
4079 appear to be on the channel. The affected file is
4080 irssi/src/silc/core/silc-channels.c.
4082 * Always update the conn->current_channel when executing command
4083 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4085 * Fixed the KILL notify handling in Irssi SILC client to remove
4086 the killed client on all channels.
4088 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Fixed the silc_parse_command_line to remove extra spaces
4091 from the start and end of the arguments. Affected file is
4092 lib/silcutil/silcutil.c.
4094 * Cancel and free any active protocol in the function
4095 silc_server_close_connection. Affected file silcd/server.c.
4097 * Cancel and free any active protocol in the function
4098 silc_client_close_connction. Affected file is
4099 lib/silcclient/client.c.
4101 * Do not execute the KILL command for clients that are in
4102 history (ie. they are not in the network). Affected file is
4105 * Fixed KILL notify handling, client does not crash anymore.
4106 Affected file irssi/src/silc/core/silc-channels.c.
4108 * Reduced the default packet buffer size from 2048 to 1024 in
4109 lib/silccore/silcpacket.c.
4111 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4112 counter to the SKE context that is incresed when the SKE library
4113 performs async operation outside the library. If the outside
4114 process frees the SKE context and FREED status will be set
4115 and the library will detect after the sync operation that the
4116 libary is freed. The affected files are
4117 lib/silcske/silcske[_status].[ch].
4119 * Resolve the client entry information in the function
4120 silc_client_channel_message to assure that NULL pointer is not
4121 passed as client entry to the application. */
4123 * Fixed the task timeout calculation to assure that there is
4124 never negative timeouts. The affected file is
4125 lib/silcutil/silcschedule.c.
4127 * Fixed the channel user mode notification sending in server.
4128 It was sent point-to-point to the router (or to server by router)
4129 but it needs to be destined to a channel. The routines now
4130 supports sending the channel user mode notifys to the channels
4131 when announcing clients and channels. Affected files are
4132 silcd/server.c and silcd/packet_receive.c.
4134 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4135 It did not actually replace the old channel entry in the cache.
4136 Affected file lib/silcclient/client_notify.c.
4138 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Fixed a possible crash in silc_packet_send_prepare. It now
4141 assures always that there is enough space in the buffer and
4142 at the tail area of the buffer (for MAC).
4144 Fixed the inbound buffer reallocation in silc_packet_read.
4145 It was old code and did not handle the reallocation correctly.
4148 The affected file is lib/silccore/silcpacket.c.
4150 * Fixed buffer overflow in silc_parse_nickname in the file
4151 lib/silcutil/silcutil.c.
4153 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4155 * make install generates new server keys only if there is not
4158 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4161 Added check that if the NOREPLY is set then we will not send
4162 the away message. This avoids infinite loop of away messages
4163 if both clients are away. The affected file is
4164 lib/silcclient/client_prvmsg.c.
4166 * Fixed client crash if /NICK was given without arguments.
4167 Affected file lib/silcclient/command.c.
4169 * Server does not send the invite list in INVITE command back
4170 to the client if the list was not altered. Added this notion
4171 to the protocol spec as well. Affected file silcd/command.c.
4173 Fixed possible crash in INVITE command by checking the
4174 value of silc_server_get_client_route command.
4176 * Fixed the INVITE notify type handling. The arguments are now
4177 taken in correct order and client does not crash. The affected
4178 file is irssi/src/silc/core/silc-channels.c.
4180 Removed the "Inviting xxx to channel" message from the
4181 client library away and let the application handle it.
4182 Affected file lib/silcclient/command.c. Added that message
4183 to Irssi SILC client's message formats.
4185 * Fixed CMODE command crash in client. It now checks the
4186 amount of arguments correctly and does not crash. The affected
4187 file is lib/silcclient/command.c.
4189 * Do not create new channel automatically in silc_channels_join
4190 but check whether the channel by that name already exists.
4191 Affected file irssi/silc/core/silc-channels.c.
4193 * Do not send the SERVER_SIGNOFF to router if the disconnected
4194 entity was the router. Affected file silcd/server.c.
4196 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4197 SILC client as it was missing from there.
4199 Added the handling of the KICK notify to the Irssi SILC client
4200 as it was missing. Added "you have been kicked" message to
4201 Irssi SILC client's message modules formats.
4203 Added the handing of the KILL notify to the Irssi SILC client
4204 as it was missing. Added the kill message module formats
4207 The affected file is irssi/src/silc/core/silc-channels.c.
4209 * The router did not save the channel mode the server announced.
4210 Affected file silcd/packet_receive.c.
4212 * Fixed a possible crash in INFO command in server. If the
4213 server did not provide the server info it crashed. Affected
4214 file silcd/command.c.
4216 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Fixed the GETKEY command in the server to check also the
4219 global list. Otherwise the GETKEY would not work correctly
4220 in normal SILC server. Affected file silcd/command.c.
4222 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Fixed GETKEY crash, it crashed if the command did not succseed.
4226 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4228 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4229 is now real and not just an macro interface to GMP.
4231 Removed the entire GMP from the source tree and imported new
4232 NSS MPI library instead. Reason for removing GMP is that it is
4233 extremely large and compiles extremely slow. The NSS MPI
4234 is only a few files and compiles in less than 10 seconds.
4235 The speed is also about the same as GMP. The MPI is imported
4236 to lib/silcmath/mpi.
4238 If the system has GMP installed we will still use the GMP.
4239 If it is not then the NSS MPI will be compiled.
4241 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4243 * Merged a long nickname (127 characters long) crash bugfix from
4244 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4246 * Merged a freed memory reference bugfix from Irssi CVS tree.
4247 Affected file irssi/src/core/commands.c.
4249 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Added the server's public key sving and verification to the
4252 server when performing the SKE. This was missing and the
4253 remote server's (or router's) public key was accepted without
4254 checking whether we have it previously or trust it at all.
4255 Affected file silcd/protocol.c.
4257 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4259 * Check in the silc_server_timeout_remote if protocol is active
4260 and make sure that the protocol's final callback is called so
4261 that all memory if freed. Affected file silcd/server.c.
4263 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * silc_server_whois_send_reply crashed the server if the nickname
4266 was 127 characters long. Affected file silcd/command.c.
4268 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Added sanity check to the silc_server_new_client. If the hostname
4271 is provided inside username then check that the provided hostname
4272 really is the same as the resolved one. If the hostname was not
4273 resolved then check it from the public key. Affected file is
4274 silcd/packet_receive.c.
4276 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4277 if the server disconnected us and the connection is not valid
4278 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4280 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4281 the library to the lib/silcutil/silcutil.[ch].
4283 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Close log file after open. Affected file
4286 lib/silcutil/silclog.c.
4288 * Check whether sock == NULL in silc_client_send_packet and return
4289 if it is. Affected file lib/silcclient/silcclient.c.
4291 * Check rec->entry == NULL in the Irssi SILC Client before
4292 sending the channel message. Affecte file is
4293 irssi/src/silc/core/silc-servers.c.
4295 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Merged a splitted window bugfix from Irssi CVS tree. The
4298 affected file is irssi/src/fe-text/textbuffer-view.c.
4300 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4301 It did not print nickname.
4303 * Improved the distributions system a bit.
4305 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4308 irssi/src/fe-text/gui-window.c.
4310 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4311 to in-active server. The affected file is
4312 irssi/src/silc/core/client_ops.c.
4314 * Resolve the client in USERS command reply if the entry does
4315 not have username resolved. The affected file is
4316 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4317 command to WHOIS command to really resolve stuff. The USERS
4318 is not used any more in any critical section so WHOIS can
4319 be used even though it might be slower than IDENTIFY.
4321 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4324 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4326 * Changed the protocol API a bit more consistent in the
4327 lib/silccore/silcprotocol.[ch].
4329 * Changed the following headers to ROBODoc format:
4331 lib/silccore/silcpayload.h
4332 lib/silccore/silcprotocol.h
4333 lib/silccore/silcsockconn.h
4335 All core library headers are now formatted.
4337 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4339 * Fixed a bug in Irssi SILC client; do not show that you are
4340 server/router operator if you really are not. Affected file is
4341 irssi/src/silc/core/client_ops.c.
4343 * Renamed silc_command_free_payload to silc_command_payload_free.
4344 Affected file lib/silccore/silccommand.h
4346 * Added silcmath.h to include the prototoypes of various routines
4347 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4350 * Changed the following headers to ROBODoc format:
4352 lib/silccore/silcchannel.h
4353 lib/silccore/silccommand.h
4354 lib/silccore/silcid.h
4355 lib/silccore/silcidcache.h
4356 lib/silccore/silcmode.h
4357 lib/silccore/silcnotify.h
4358 lib/silccore/silcpacket.h
4359 lib/silcmath/silcmath.h
4361 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4363 * Added checking to the server code not to start the server if
4364 ciphers and stuff are not configured properly. Affected files
4365 silcd/serverconfig.[h] and silcd/server.c.
4367 * Changed the layout of the header files of the public interfaces
4368 in the SILC libraries. The new layout supports ROBODoc
4369 documentation tool (and some others) so that it is easy to create
4370 a library reference manual. All the other headers and source
4371 code must still follow the CodingStyle document. Also source
4372 code must not include these ROBODoc stuffs, only the headers.
4373 Furthermore, all public interface headers must now be named
4374 by using `silc' prefix, example: silcapi.h, silccipher.h.
4375 Some files were renamed due to this. All the other headers
4376 must not be used as public interfaces. I will update the
4377 CodingStyle document later. Changed following headers, so far:
4379 lib/silcclient/silcapi.h
4380 lib/silccore/silcauth.h
4381 lib/silccore/silcprivate.h
4382 lib/silccrypt/silcdh.h
4384 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Removed silc_client_packet_send_flush from the client library
4389 as it is not needed. Affected file lib/silcclient/client.[ch].
4391 * Added printing of message of unresolved authentication method
4392 to the Irssi SILC client. Added it to the module formats.
4393 Removed the same message from the client library.
4395 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added new distribution feature, DISTLABEL. Every distribution
4398 can define own preprocessor label that can be used in the
4399 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4400 file distributions, acconfig.h.pre and prepare.
4402 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Added Makefile.defines_int to include the actual definitions
4405 for Makefile.defines.in. Tested the new distribution system,
4406 created distributions and tested installation.
4408 * Added AWAY message printing to the Irssi SILC client. Added
4409 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4411 * Added SCONNECT command to call the SILC's CONNECT command.
4412 Cannot use CONNECT directly since Irssi uses that internally.
4413 Affected file irssi/src/silc/core/silc-servers.c.
4415 Added ACTION local command. It is same as ME command but takes
4416 the channel as mandatory argument.
4418 Rewrote some of the Irssi's help files to suite for SILC
4421 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Added Makefile.defines[.in] that should for now on be included
4424 in all Makefile.am file in the source tree. That file includes
4425 all common compilation definitions for SILC source tree.
4427 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Minor changes to the ./prepare script to change the package
4430 name according the distribution name to the configure.in.
4432 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4434 * Created new distribution system. Added file `distributions'
4435 that defines all the distributions that can be created out of
4436 the SILC source tree. The ./prepare script now reads that
4437 file to determine how to prepare the distributions. The
4438 first argument to the ./prepare is the name of the distribution
4439 and second is the version of the distribution. If given
4440 without arguments it creates the default (toolkit) distribution
4441 with the default version (defined in ./prepare).
4443 All Makefile.am files that are subject to the distributions
4444 are now named as Makefile.am.pre. These are ./Makefile.am
4445 and lib/Makefile.am. Others may be changed later.
4447 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Added invite list, ban list, some key management and connection
4450 error message printing to module formats in the Irssi SILC client.
4452 * Added new silc_client_set_away_message to set the away message
4453 that is back to the person who sent private message. The
4454 affected file lib/silcclient/silcapi.h and the
4455 lib/silcclient/client_prvmsg.c.
4457 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4459 * Fixed the private message sending in the Irssi SILC client,
4460 added local command KEY to the Irssi SILC client.
4462 Added key management and key agreement message formats to the
4463 irssi/src/fe-common/silc/module-formats.[ch].
4465 Added USERS (alias WHO) printing, server/router operator
4466 indication and LIST command printing to the module formats.
4468 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4470 * Fixed channel joining notify handling, cumode notify handling
4471 from Irssi SILC client.
4473 * Added SILC specific module-formats to the Irssi SILC client so
4474 that SILC specific message hilighting, colors etc is possible.
4475 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4477 Added channel mode, channel user mode, actions, notices,
4478 whois and whowas printing to the the module-formats.c.
4480 * Fixed a bug in channel deletion in the server. The channel
4481 is not left to the cache even if the channel founder auth mode
4482 is set when there are no users anymore on the channel. Affected
4483 file silcd/server.c.
4485 * The silc_net_localhost now resolves the entire hostname including
4486 the domain name. Affected file lib/silcutil/silcnet.c.
4488 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Changed the ask_passphrase client operation to be ascynchronous.
4491 It has now a completion callback and a context that the
4492 application must call after it has got the passphrase from
4493 the user. Affected files lib/silcclient/silcapi.h,
4494 lib/silcclient/protocol.c, lib/silcclient/command.c and
4497 Added SilcAskPassphrase callback that the application calls
4498 to deliver the passphrase to the library.
4500 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4501 The public key verification and especially a certificate
4502 verification is asynchronous procedure.
4504 Added new SILC_SKE_STATUS_PENDING status to indicate the
4505 request is pending and a callback will be called to finalize
4508 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4509 indicate that remote end did not send its public key (or
4510 certificate), even though we require it. Added check for this
4511 condition in the SKE. This was a security bug, now fixed.
4513 Defined new SilcSKEVerifyCbCompletion callback that is called
4514 when the verification process is completed.
4516 The affected files lib/silcske/silcske_status.h and
4517 lib/silcske/silcske.[ch].
4519 * Changed the verify_public_key client operation to be async
4520 as well. Defined SilcVerifyPublicKey callback that is used to
4521 indicate the success of the public key verification process.
4523 Changed the server and client to use the new async client
4526 * Changed the Irssi SILC client's internal scheduler to be called
4527 twice as many times as it used to be. As a result the client
4528 should be a bit faster now. Affected file is
4529 irssi/src/silc/core/silc-core.c.
4531 * Added support to Irssi SILC client of asynchronous public key
4532 verification and passphrase inquiry. Affected file is
4533 irssi/src/silc/core/silc-core.c.
4535 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4537 * Do not say "You have left channel %s" in client library.
4538 Moved it to the application. Affected files are
4539 lib/silcclient/command.c and silc/client_ops.c.
4541 * Fixed silc_client_get_clients. Command context was not
4542 duplicated and was freed memory in the callback. Affected
4543 file lib/silcclient/idlist.c.
4545 * Do not say "you are now talking..." on JOIN command in the
4546 client library. The appliation must handle it.
4548 * Do not say ".. changed topic to" in command reply in the
4549 client libary. The application must handle it.
4551 * Fixed TOPIC command sending in the client library.
4553 * Fixed a memory leak in silc_client_command_free in the file
4554 lib/silcclient/command.c.
4556 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Imported a modified version of Irssi client to the source tree.
4559 The Irssi will be used to create a new client called
4560 Irssi SILC. Imported to irssi/.
4562 Added silc_core_init_finish function to the Irssi. Affected
4563 file irssi/configure.in.
4565 A lot changes in the Makefile.ams around the irssi tree.
4567 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Do not rehash if the new size is same as the old size of the
4570 hash table, in the silc_hash_table_rehash*. The affected file
4571 lib/silcutil/silchashtable.c.
4573 * Replaced hash_table_del_by_context calls from the server
4574 (when channel->user_list and client->channels) to the
4575 hash_table_del as it is sufficient and faster.
4577 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Added silc_hash_table_list, silc_hash_table_get and the
4580 SilcHashTableList structure to provide an alternative way to
4581 traverse the hash table. The affected files are
4582 lib/silcutil/silchashtable.[ch].
4584 * Changed the server's idlist routines to use the hash table
4585 routines to optimize the code.
4587 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4589 * Replaced the client entry's `channel' list and channel entry's
4590 `user_list' list to hash tables for optimized lookup. Changed
4591 the code to use the hash table interface around the code.
4592 Affected file lib/silcd/idlist.[ch].
4594 * Added `auto_rehash' boolean argument to the function
4595 silc_hash_table_alloc to indicate whether the hash table should
4596 auto-rehash when it thinks is appropriate time. It will
4597 increase the hash table size if the there is twice as much
4598 entries in the table than the size of the table, and will
4599 decrease the size if there are twice as less entries than
4600 the size of the table.
4602 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4606 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4608 * silc_idcache_purge_by_context deletes the entry now by context
4609 as it is supposed to do. Affected file lib/silccore/idcache.c.
4611 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4612 client is not anymore valid (WHOWAS givens the info) and not
4613 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4615 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Removed the `data' and `data_len' arguments from the ID Cache
4618 interfaces and added `name' argument. ID Cache does not handle
4619 anymore the binary data only a names associated with given ID.
4621 * When hashing a Client ID with silc_hash_id the entire ID is
4622 not hashed anymore, instead only the hash of the Client ID is
4623 hashed. This way we can access the Client ID from the cache
4624 with Client ID but with the hash of the ID (which is a hash of
4625 the nickname) as well without any difference in performance.
4627 Added also silc_idcache_find_by_id_one_ext to do one on one
4628 searching when we have the actual ID. Added also function
4629 silc_hash_client_id_compare. The affected files are
4630 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4632 * When hashing the name associated with a ID it is always done
4633 in lowercase. This way we can access the cache without worrying
4634 about case-sensitivity, even though, for example nicknames are
4637 * Fixed a bug in server with channel message sending. It put
4638 wrong ID type as destination ID. The affected file
4639 silcd/packet_send.c.
4641 * silc_idcache_del_by_context now deletes from all hash tables
4642 by context. Affected file lib/silccore/idcache.c.
4644 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Changed the client library to use the new ID Cache interface.
4647 Changes around the source tree.
4649 * Added silc_hash_table_rehash_ext to rehash with specific
4650 hash function. Affected file lib/silcutil/silchashtable.[ch].
4652 * Added silc_hash_string_compare to compare two strings in the
4653 hash table. Affected file lib/silcutil/silcutil.[ch].
4655 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added new function silc_idcache_del_by_context into the
4658 lib/silccore/idcache.[ch].
4660 * Changed the server's ID list routines to use the new ID Cache
4661 interface. Changes around the source tree.
4663 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4665 * Added silc_hash_table_del[_by_context]_ext functions in to the
4666 lib/silcutil/silchashtable.[ch].
4668 Removed silc_hash_table_find_all* routines and added new
4669 silc_hash_table_find_foreach to replace them.
4671 Added silc_hash_table_replace_ext function as extended
4672 replacing function. Separated the simple hash table interface
4673 from the extended hash table interface in the file
4674 lib/silcutil/silchashtable.h.
4676 * Fixed minor bugs and changed it to use some of the new
4677 hash table functions in lib/silccore/idcache.c
4679 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4681 * Added new function silc_hash_table_find_all to return all keys
4682 in the hash table by the specified key. As the hash table is
4683 collision resistant it also makes it possible to have several
4684 duplicate keys in the hash table. This function may be used to
4685 find all of the keys from the hash.
4687 Added user_context arguments to the SilcHashFunction,
4688 SilcHashCompare and SilcHashDestructor to deliver user specified
4691 Added new fuctions silc_hash_table_find[_all]_ext to do
4692 extended lookup with specified hash and compare functions and
4693 specified user contexts.
4695 Added new function silc_hash_table_add_ext to add the key
4696 with specified hash function and user context.
4698 Added new function silc_hash_table_foreach to traverse all
4699 entrys in the hash table. Added SilcHashForeach callback
4702 Added new function silc_hash_table_del_by_context to delete
4703 the entry only if the context associated with the key matches.
4705 Affected files are lib/silcutil/silchashtable.[ch].
4707 * Removed silc_hash_[server/client/channel]_id and added just
4708 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4709 silc_hash_id_compare to compare two ID's using as the hash table
4710 comparison function. Added also silc_hash_data to hash
4711 binary data and silc_hash_data_compare to compare it.
4713 * Removed silc_idlist_find_client_by_hash as it is not needed
4714 anymore. Affected file silcd/idlist.[ch].
4716 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4717 to use internally the SilcHashTable. The new ID Cache is a lot
4718 faster than the old one. Some of the ID Cache interface was also
4719 rewritten and obsolete and stupid functions were removed.
4721 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4723 * Added entry_count field to the SilcHashTable to keep the number
4724 of the entries in the table. Implemented the function
4725 silc_hash_table_rehash. Added new function
4726 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4728 Fixed a minor bug in silc_hash_table_free.
4730 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4731 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4732 into the lib/silcutil/silcutil.[ch].
4734 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4736 * Implemented a collision resistant hash table into the
4737 lib/silcutil/silchashtable[ch]. See the header and the source
4738 for the SilcHashTable API.
4740 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4742 * Merged dotconf version 1.0.2 into lib/dotconf.
4744 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4746 * Do not compile anything in lib/silcsim/* if the SIM support
4747 is not enabled. The tree should now compile without problems
4750 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4752 * Compiled the SILC under cygwin. Compiled and tested briefly
4753 without problems. More tests needed. The SIMs didn't compile
4756 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4758 * Fixed possible crash in silc_get_username in the
4759 lib/silcutil/silcutil.c.
4761 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Fixed a va_arg in silc/client_ops.c.
4765 * Oops, RC5 routines were named AES and caused some problems
4766 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4768 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added new SilcIDIP structure into the lib/silccore/id.h and
4771 replaced the old `ip' fields from all SILC ID's to that type.
4772 This is a step towards IPv6 support.
4774 The silc_id_get_len takes now the ID as an extra argument.
4775 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4776 both IPv4 and IPv6 based ID's.
4778 The affected files are lib/silccore/id.[ch] and other files
4779 around the tree using these routines.
4781 * Removed the ID length arguments in server from various
4782 silc_server_send_notify_* routines -> they are not needed
4785 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Fixed memory leak in silc_encode_pem_file in the file
4788 lib/silcutil/silcutil.c.
4790 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Check minor version as well in the SKE. Affected files are
4793 silcd/protocol.c and lib/silcclient/protocol.c.
4795 * Added --identifier option to the server so that an identifier
4796 can be when creating the public key for the server. Affected
4797 file is silcd/silcd.c.
4799 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4800 lib/silccrypt/silcpkcs.c.
4802 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Register default ciphers and stuff when using -C option with
4805 the server. Affected file sildc/silcd.c.
4807 * Put back the servers public key filename format, it is better
4808 than the new one. For now, the client keys are saved with the
4809 new filename format. The affected file silc/client_ops.c.
4811 * Implemented the Cipher API for the rest of the ciphers that
4812 did not implement it or implemented it the wrong way.
4814 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Register default ciphers and stuff when using the -S option
4817 in the client. Affected file silc/silc.c. Same also when
4818 creating new key pair with -C option.
4820 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Fixed the silc_verify_public_key client operation function to
4823 save the public keys differently. The fingerprint is now
4824 used as filename and not the hostname. This way also the
4825 client keys are saved uniquely and not with hostnames. The
4826 affected file is silc/client_ops.c.
4828 * Trimmed the silc_hash_fingerprint function to remove extra
4829 whitespaces from the end of the fingerprint. The affected
4830 file is lib/silccrypt/silchash.c.
4834 * Added silc_cipher_register_default function to register all
4835 default ciphers. It can be used when configuration files
4836 does not exist and the application does not want any specific
4837 ciphers in any specific order.
4839 The SilcDList is now used as silc_cipher_list dynamically
4840 allocated cipher list. Removed the static list all together
4841 and now all ciphers must be allocated to the dynamic list.
4842 The silc_cipher_alloc routine was changed to check only the
4845 All silc_cipher_* routines that used to return int returns
4848 The affected files lib/silccrypt/silccrypt.[ch].
4850 * The same thing was done to silc_hash_* as for silc_cipher_*
4851 routines. Affected files lib/silccrypt/silchash.[ch].
4853 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4854 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4855 Added also silc_pkcs_[un]register[_default] functions.
4856 Removed the data_context from the PKCS API.
4858 * Added silc_hmac_register_default function to register default
4859 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4860 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4861 to unregister all hmacs at once.
4863 * Register the default ciphers, hash functions, PKCSs and HMACs
4864 if client's configuration file does not exist. The affected
4867 * The client did not load the hash functions from the SIM
4868 modules at all. Added support for this. Affected file is
4869 silc/clientconfig.c.
4871 * When decoding public key with silc_pkcs_public_key_decode, check
4872 the supported algorithm only if PKCS are registered. Affected
4873 file lib/silccrypt/silcpkcs.c. The same was done with the
4874 silc_pkcs_private_key_decode.
4876 * Fixed the SILC List routines to keep the list always in order.
4877 It used to change the list's order when traversing the list but
4878 not it preserves the order. Affected file lib/trq/silclist.h.
4880 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4882 * Added the client library to use the SilcSocketConnection's
4883 reference counter (by silc_socket_dup) to prevent the bug that
4884 the socket object may be freed underneath async operation.
4886 * The name resolv library checking fixes in the configure.in.pre.
4889 * Created new version of the protocol drafts for future
4890 development. The -03 drafts are the ones that will be changed
4891 in the trunk now and the -02 will remain as they are.
4893 * Send list of CUMODE notifys to the router when announcing
4894 the channel users to the router. Affected file silcd/server.c.
4895 If the router receiving channel founder CUMODE for a channel
4896 that already has channel founder it will send CUMODE notify
4897 to the sender to remove the channel founder rights from the
4898 announced client. Affected file silcd/packet_receive.c.
4900 * The CUMODE notify may now use Server ID as well as the entity
4901 who changes the mode. Updated protocool specs.
4903 * Updated INSTALL and README files.
4905 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * New web pages in the http://silc.pspt.fi. The pages was
4912 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4914 * Implemented the [DenyConnectin] config section in the server.
4915 Added silc_server_config_denied_conn to check whether incoming
4916 connection is denied. Affected file silcd/serverconfig.[ch].
4918 * Do not check the ports when checking the incoming configuration
4919 data if the port is 0, meaning any. Affected file is
4920 silcd/serverconfig.c.
4922 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Fixed buffer overflow in silc_string_compare in the file
4925 lib/silcutil/silcutil.c.
4927 * Fixed double free in silc_server_command_leave in the file
4930 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4932 * Fixed the version checking in the server. Affected file is
4935 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed the configuration data fetching when accepting new
4938 connections in the server. Affected file silcd/server.c.
4940 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Added `sender_entry' argument to the function
4943 silc_server_packet_relay_to_channel so that we can check
4944 whether some destination actually belongs to the same route
4945 the sender belongs (ie, we must not resend the packet to the
4946 sender). Affected file silcd/packet_send.[ch].
4948 * Added `servername' field to the SilcClientEntry in the server
4949 to hold the name of the server where client is from. Affected
4950 file is silcd/idlist.h.
4952 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4954 * Moved the channel message encrypting in the router betwen
4955 router connections from silc_server_channel_message to the
4956 silc_server_packet_relay_to_channel since we want to check
4957 whether we have anybody channel before encrypting anything.
4958 Affected files silcd/packet_[receive/send].c.
4960 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4962 * Fixed the [AdminConnection] server config section to support
4963 multiple entries. Affected file silcd/serverconfig.c.
4965 * Added support into the server to check the validity of the
4966 incoming connection before executing any KE or authentication
4969 * The connection configuration is now saved to the KE and
4970 connection auth protocol contexts and not fetched anymore in
4971 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4973 * The local hosts listenning address and port is also resolved
4974 now when starting the server. We want to have the socket object
4975 to include the real address and port for the listener. Added
4976 new function silc_net_check_local_by_sock into the files
4977 lib/silcutil/silcnet.[ch].
4979 * Fixed a broadcast bug in server -> do not broadcast if we
4982 * Fixed a routing bug. Do not route broadcast packets ever.
4983 Broadcast packets must be processed always and not routed since
4984 they may be destined to some other host than yourself and thus
4985 would get routed without no good reason. Affected file is
4988 * Added function silc_server_config_is_primary_route to check
4989 whether primary router connection has been configured (a router
4990 configuration that we are initiating). If there is not, we
4991 will assume that there is only two routers in the SILC network
4992 and we will use the incoming router connection as our primary
4993 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4995 * Changed the order of the broadcasting. Broadcast _after_ the
4996 packet has been processed not before. Affected file is
4999 * Fixed a [ClientConnection] parsing bug. The port was never
5000 parsed correctly thus resulting to port 0. Affected file
5001 silcd/serverconfig.c.
5003 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5004 argument and did not set the broadcast packet flag. Affected
5005 file silcd/packet_send.c. Fixed same bug in the function
5006 silc_server_send_notify as well.
5008 * If we receive NEW_ID packet for our own ID in the server, ignore
5011 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Removed the nickname from the Private Message Payload.
5016 Updated the code and the protocol specs.
5018 * Updated protocol specs for submitting to the IETF.
5020 * Tweaked the Random Number Generator a bit. Affected file
5021 lib/silccrypt/silcrng.c. Exported a new function
5022 silc_rng_[global]_add_noise which can be used to add more
5025 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Do not parse packets with different timeout when protocol
5028 is active -> may cause problem with rekey. Affected file
5031 * When server receives signoff notify it must not create
5032 new channel key if the client is on any channels since the
5033 sender of the signoff notify will create it.
5035 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Added printing of error messages during SKE protocol from the
5038 failure packet sent by server during SKE. Affected file
5041 * Removed the client's failure_callback handling with timeout
5042 and handle it immediately when received.
5044 * The SKE library returned wrong type in SUCCESS and FAILURE
5045 packets. They must be 32 bit MSB not 16 bit MSB.
5047 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5049 * Ok, rewrote the logic of the re-key and now it seems to work.
5050 I tested it on high traffic with frequent re-keys without
5051 problems. Added hmac_receive (and renamed hmac to hmac_send)
5052 in SilcClientConnection in lib/silcclient/client.h and
5053 in SilcIDListData in silcd/idlist.h. Also, removed the
5054 SilcPacketParserContext's cipher and hmac fields as they are
5055 not needed anymore and actually caused some problems when
5056 the ciphers and hmac's changed underneath the packet parser.
5058 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5060 * If re-key protocol is active then process the incoming packets
5061 synchronously since we must assure that icoming packets encrypted
5062 with the old key is processed before the new keys is set to
5063 use. This is true other packets than for REKEY packets.
5064 Affected file silcd/server.c. The same was done to client library
5065 as well, affected file lib/silcclient/client.c.
5067 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5069 * Fixed bug in client and server to accept the force send if
5070 the packet is send from silc_[server/client]_packet_process
5071 function. Otherwise the packets are never delivered, oops.
5073 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Disable force sending of packets when REKEY protocol is active.
5076 We must assure that no packet is sent directly when rekey is
5077 performed. All packets must be sent through packet queue.
5078 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5079 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5080 function is silc_[server/client]_packet_send_real to check
5083 * Replaced the SIM paths from example config files to
5084 /usr/local/modules. Also, make install creates now
5085 /usr/local/silc/logs directory to hold all the SILC server
5088 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Made the configure.in.pre work on Solaris. Patch by salo.
5092 * Made all ciphers compatible with non-x86 machines. Defined
5093 CBC mode macros into lib/silccrypt/ciphers_def.h.
5095 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Fixed the make install.
5099 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * When MAC computation fails the silc_packet_decrypt returned 0
5102 even though it was supposed to return -1. Fixed this. The
5103 affected file is lib/silccore/silcpacket.c.
5105 * Do not replace the config files in /etc/silc (in make install)
5106 if they already exist. Affected file ./Makefile.am.
5108 * Do not send re-key packets immediately but through packet queue.
5109 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5111 * Changed silc_net_check_host_by_sock to return FALSE if the
5112 IP/DNS could not be resolved. Though, it returns the IP address
5113 now even if it could not resolve it (but returns also FALSE).
5114 Affected file lib/silcutil/silcnet.[ch].
5116 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5118 * Added silc_pkcs_decode_identifier to decode the public key's
5119 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5120 Added also silc_pkcs_free_identifier. Added also new context
5121 SilcPublicKeyIdentifier.
5123 * Added -S option to the silc client. It is used to dump the
5124 contents of the specified public key file.
5126 * Changed the PKCS api to return the public key length when
5127 setting the public key.
5129 * Fixed a fatal bug in the public and private key file loading.
5130 Affected file lib/silccrypt/silcpkcs.c.
5132 * Execute the packet parsing for client with zero (0) timeout
5133 if the protocol is active. Affected file silcd/server.c.
5135 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5137 * Made the key generation options to the silcd program. Added
5138 -C option, equivalent to client's option.
5140 * Added new [ServerKeys] config section to the server. It
5141 configures the server's public and private key.
5143 * Defined generic Public Key Payload into the protocol
5144 specification to send specific type of public keys and
5147 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5148 public key or certificate.
5150 * Implemented the GETKEY command to the server and to the
5151 client library and on user interface.
5153 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Made preliminary `make install' work.

5172 state of the protocol. Affected file is
5173 lib/silccore/silcprotocol.[ch].
5175 * Added the re-key support with and without PFS to the client
5176 library. Re-key is performed once in an hour, by default.
5178 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5179 Added silc_client_rekey_callback and silc_client_rekey_final.
5180 Affected files are lib/silcclient/protocol.[ch] and

5183 * Removed the `hmac_key' and `hmac_key_len' fields from the
5184 SilcClientConnection structure; not needed. Affected file is
5185 lib/silcclient/client.h.
5189 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Do not ask whether user wants to use the negotiated private key
5192 for private messages, just use it. Affected file is
5193 silc/local_command.c.
5195 * Added `send_enc_key' and `enc_key_len' fields to the
5196 SilcIDListData structure since they are needed in the re-key
5197 phase. Affected file is silcd/idlist.[ch].

5211 the PFS is to be performed in the re-key. Affected file is
5214 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5217 int64 of at least the xintXX size. If void * is less that 4
5218 bytes uint32 * will be used. Defined bool as boolean.
5220 * Changed _ALL_ unsigned long and unsigned int to uint32,
5221 unsgined short to uint16 in the source tree.
5223 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5224 not handle clients that has entry->data.registered == FALSE.
5225 They are not in the network anymore. Affected file is
5228 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5230 * Implemented the sending of the SERVER_SIGNOFF notify in the
5231 server. Affected file is silcd/server.c.
5233 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5234 Added also silc_notify_payload_encode_args into the
5235 lib/silccore/silcnotify.[ch].
5237 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5238 Affected file silcd/packet_receive.c.
5240 * Implemented the SERVER_SIGNOFF notify handling in the client
5241 library. Affected file lib/silcclient/client_notify.c. Also,
5242 implemnted the printing of the SERVER_SIGNOFF info to the
5243 application. Affected file silc/client_ops.c.
5245 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5246 if the deleting was successful. Affected file silcd/idlist.[ch].
5248 * Added support for public key authentication in the connection
5249 authentication protocol in the client library. Affected file
5250 lib/silcclient/protocol.c.
5252 * Changed the server's silc_idlist_get_clients_by_* interface
5253 to support already allocated array so that new entries may be
5254 added to pre-allocated array. Affected file silcd/idlist.[ch].
5255 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5256 and command replies.
5258 * All command reply functions in the server now calls the
5259 pending command callback even if error occured. This way the
5260 error will be delivered to the client as well. Affected files
5261 silcd/command.c and silcd/command_reply.c.
5263 * Fixed INFO command to return local server's info if no server
5264 was provided. Affected file lib/silcclient/command.c.
5266 * Removed RESTART command for good. Updated the code and the
5269 * Rewrote parts of the task system. It is a bit simpler now.
5270 Removed unsued task priorities. The affected files are
5271 lib/silcutil/silctask.[ch].
5273 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Moved the USERS printing from the library to the application.
5276 Affected files lib/silcclient/command.c and silc/client_ops.c.
5278 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Added channel key re-key support. The re-key is perfomed
5283 only by the router and is done once in an hour. Added `rekey'
5284 field to the SilcChannelEntry in the server. Affected files
5285 silcd/server.c and silcd/idlist.h.
5287 * Added silc_task_unregister_by_context into the file
5288 lib/silcutil/silctask.[ch].
5290 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Added SILC_UMODE_GONE mode to indicate when the client is not
5293 present in the SILC network. Added also support to the local
5294 command AWAY that will set this mode. Added support of showing
5295 "xxx is gone" in WHOIS command. The USERS command shows the
5296 gone status as well.
5298 * Fixed setting server and router operator privileges in the
5299 server's UMODE command. Affected file silcd/command.c.
5301 * Merged the SKE KE1 and KE2 payloads into one payload. The
5302 new KE payload is equivalent to the old KE2 payload.
5304 Cleaned up the SKE Start Payload parsing. It now uses the
5305 simple buffer unformatting to do the parsing. A lot faster
5308 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5309 to the SKE that is used to indicate whether both of the SKE
5310 parties should perform authentication. By default only the
5311 responder performs authentication. By setting this flag also
5312 the initiator must do authentication. By default it is unset
5313 since in normal SKE case, client to server connection, only
5314 the responder should do authentication. When doing SKE between
5315 two clients both should perform authentication. Updated the
5316 code and the protocol specs.
5318 * A little fix to IDENTIFY command in the server. Search the
5319 client first by hash not nickname. Affected file is
5322 * Fixed the silc_client_close_connection to support closing
5323 the client to client connections wihtout deleting too much
5324 data. Affected file lib/silcclient/client.c.
5326 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5327 are received if protocol used to be active but is not anymore
5328 the application would crash due to NULL pointer dereference.
5329 Affected files silcd/server.c and lib/silcclient/client.c.
5331 * Added `hash' field to the SilcClientConnection to include
5332 the hash function negotiated in the SKE protocol.
5334 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5335 to set the channel founder authentication data. A client can
5336 claim the founder rights later by providing the authentication
5337 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5338 This way the channel founder can regain the channel founder
5339 privileges even it is left the channel. This works only on
5340 local server and the client must be connected to the same
5341 server to be able to regain the founder rights. Updated the
5342 protocol specs accordingly.
5344 Added support to the CMODE command in the client to set the
5345 founder auth data. Read the README to see how to set it.
5347 Added support to the CUMODE command to claim the founder
5348 rights. Read the README to see how to do it.
5350 Added support for the founder authentication to the Channel
5351 Entry in the server. Affected file silcd/idlist.h.
5353 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5354 server's CMODE command. Affected file silcd/command.c.
5356 * Added the following new functions into lib/silccore/silcauth.[ch]:
5357 silc_auth_get_method and silc_auth_get_data.
5359 * The server now saves the remote hosts public key to the
5360 SilcIDListData pointer. Affected file silcd/protocol.c.
5362 * The normal server now does not remove the channel entry from
5363 the cache if the founder authentication data is set. It used
5364 to remove it if the founder was the last one on the channel on
5365 the server and left the channel. The auth data is saved and
5366 if the channel is re-joined later the old entry is used with
5367 the old auth data. Affected files silcd/command_reply.c and
5370 * Removed the `pkcs' field from the SilcIDListData structure
5371 in the server; it is not used. Affected file silcd/idlist.h.
5373 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5375 * Fixed packet processing on slow links. Partial packets were
5376 never re-processed because the incoming data buffer was cleared
5377 by the application. Application must not directly clear the
5378 sock->inbuf, the packet processing routines handle it. Fixed
5379 this in client library and in server.
5381 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Fixed the WHOIS and IDENTIFY send reply function to really
5384 check whether to send list or just one entry. Affected file
5387 * Cleaned up the LEAVE command's channel key distribution. The
5388 affected file silcd/command.c.
5390 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5391 can enforce the channel mode as well. In that case the ID
5392 includes the ID of the server. The code now enforces the
5393 mode change if the router have different mode than the server.
5395 * The notify client operation with CMODE_CHANGE notify can now
5396 return NULL client_entry pointer if the CMODE was not changed
5397 by client. Application must check for this.
5399 * Added <Server ID> argument to INFO command to support server
5400 info fetching by Server ID.
5402 * Added silc_server_announce_get_channel_users to get assembled
5403 packets of channel users of the specified channel. Affected
5404 file silcd/server.[ch].
5406 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5407 was freed underneath the ID Cache.
5409 * Re-announce clients when the server received CHANNEL_CHANGE
5410 notify from the router. Affected file silcd/packet_send.c.
5412 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5414 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5415 crashed since it did not handle the fact that there is no cipher
5416 called "3" and didn't check the error condition. Now fixed.
5418 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5419 flag. It can be used to send message requests.
5421 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Implemented the RESTART command in the client.
5425 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5426 notice type messages. Added notice printing to the user
5429 * The channel keys are not re-generated if the channel's mode
5430 is PRIVKEY, ie private key on the channel exists. Affected
5431 files silcd/server.c and silcd/command.c.
5433 * Fixed a little bug in channel message delivery when channel
5434 private keys are set in the server. Affected file is
5435 silcd/packet_send.c.
5437 * Changed the setting on channel->on_channel = TRUE from the
5438 silc_client_save_channel_key to the JOIN command reply. The
5439 key payload is not received if the private channel key is set.
5440 Affected file lib/silcclient/command_reply.c and the
5441 lib/silcclient/client_channel.c.
5443 * When the CMODE_CHANGE notify is sent and the channel private
5444 key mode is removed the channel key must be re-generated in
5445 other cells as well. Added this support for the router in the
5446 silcd/packet_receive.c.
5448 * Added new local command NOTICE to send notice message on
5449 channel. Affected file silc/local_command.[ch].
5451 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Added new local command ME to the client. It is used to send
5454 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5455 some action. Affected file silc/local_command.[ch].
5457 * Changed channel_message and private_message client operations
5458 to deliver the message flags to the application. Added also
5459 the `flags' arguments to the silc_client_send_channel_message
5460 and silc_client_send_private_message functions. Affected file
5463 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Redefined the Private Message Payload to support private message
5466 keys and to support the new private message flags. Updated
5467 the protocol specs. Flags makes it possible to have for example
5468 CTCP style messages.
5470 * Added new type SilcPrivateMessagePayload and defined an API
5471 for it in the lib/silcclient/silcprivate.[ch].
5473 * Tested private message private keys successfully. Tested the
5474 private message key set, unset and list commands with the new
5477 * Redefined the Channel Message Payload to include the channel
5478 message flags (equal with private message flags) to support
5479 for example CTCP style messages.
5481 * Defined some of the message (for channel and private message)
5482 flags. Updated the protocol specs and added the flags to the
5483 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5485 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Added SilcKeyAgreementStatus type to the key agreement routines
5488 to indicate the current status and error if one occured.
5489 The status types are defined in the lib/silcclient/silcapi.h.
5491 * Added new local command KEY that is used to set and unset private
5492 keys for channels, set and unset private keys for private messages
5493 with remote clients and to send key agreement requests and
5494 negotiate the key agreement protocol with remote client. The
5495 key agreement is supported only to negotiate private message keys,
5496 it currently cannot be used to negotiate private keys for channels,
5497 as it is not convenient for that purpose.
5499 * Fixed a minor pending callback setting bug in the function
5500 silc_client_get_client_by_id_resolve, now the function works.
5501 Affected file lib/silcclient/idlist.c.
5503 * Added function silc_net_get_local_port to get local bound
5504 port by socket. Added to lib/silcutil/silcnet.[ch].
5506 * Added `sockets' and `sockets_count' fields to the SilcClient
5507 object. They hold the sockets of the listenning sockets in
5508 the client. Listenning sockets may be for example the key
5509 agreement server. Affected file lib/silcclient/client.[ch].
5510 Added functions the silc_client_add_socket and the
5511 silc_client_del_socket. They are exported to the application
5514 * Added ~./silc/clientkeys to support other client's public keys.
5516 * Renamed verify_server_key client operation to verify_public_key
5517 and added one argument to indicate the type of the connection
5518 (server, client etc.).
5520 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Added silc_server_connection_auth_request to handle the
5523 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5524 silcd/packet_receive.[ch].
5526 * Added silc_server_send_connection_auth_request into the
5527 silcd/packet_send.c to send the connection auth request packet.
5529 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5532 * Fixed the public key authentication in responder side in the
5533 server. The `auth_data' pointer includes the SilcPublicKey
5534 not the path to the public key. Affected file silcd/protocol.c.
5536 * Implemented the public key authentication in the initiator side
5537 in the server. Affected file silcd/protocol.c.
5539 * Removed the [RedirectClient] config section from the server
5540 configuration. Is not needed and I don't want to implement it.
5542 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5544 * Cleaned up the CMODE command in the server. It now works
5545 correctly and supports all the modes defined in the protocol.
5546 Affected file is silcd/command.c.
5548 * Added `hmac_name' field to the SilcChannelEntry in the server
5549 to hold the default HMAC of the channel. It can be set when
5550 creating the channel (with JOIN command). Affected files
5553 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5554 type to indicate the change of the current cipher and hmac
5555 on the channel. Client can safely ignore the <cipher> argument
5556 (if it chooses to do so) since the CHANNEL_KEY packet will
5557 force the channel key change anyway. The <hmac> argument is
5558 important since the client is responsible of setting the new
5559 HMAC and the hmac key into use.
5561 * Fixed the CMODE command in the client library as well.
5563 * Tested CMODE command in router environment successfully.
5565 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Show the version of the remote client (or server) when connecting
5568 to the server. It is logged to the log file. Affected file
5569 is silcd/protocol.c.
5571 * Fixed the KILLED notify handling in the client library. The
5572 client must be removed from all channels when receiving the
5575 Also, do not remove the client entry when giving the KILL
5576 command but when the KILLED notify is received.
5578 * Removed silc_idlist_find_client_by_nickname from the server.
5579 Not needed anymore. Affected files silcd/idlist.[ch].
5581 * Implemented the CHANNEL_CHANGE notify type handling to the
5582 server. Affected file silcd/server.c.
5586 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Added silc_server_send_notify_invite to send the INVITE
5589 notify between routers.
5591 * Implemented the INVITE command correctly to the server.
5593 * Implemented the INVITE notify type handling in the server.
5595 * Implemented the INVITE command to the client library and on the
5598 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added function silc_server_get_client_resolve to find the
5601 client entry by ID from all ID lists and then resolve it
5602 (using WHOIS) if it cannot be found. Affected file is
5605 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Implemented the BAN command to the client library.
5609 * The JOIN command in the server now checks the invite list
5612 * Changed the silc_command_reply_payload_encode_va and the
5613 silc_command_payload_encode_va to support that if argument is
5614 NULL it ignores and checks the next argument. Affected file
5615 lib/silccore/silccommand.c.
5617 * Added silc_server_send_notify_ban to send the BAN notify
5618 type between routers.
5620 * Chaned the silc_notify_payload_encode to support that if
5621 argument is NULL it ignores and checks the next argument.
5622 Affected file lib/silccore/silcnotify.c.
5624 * Tested ban lists in router environment successfully.
5626 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Implemented BAN command to the server, in silcd/command.[ch].
5630 * Removed the BAN and INVITE_LIST modes from the CMODE command
5633 * Added function silc_string_match to regex match two strings.
5634 Affected files lib/silcutil/silcutil.[ch].
5636 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Redefined parts of the SilcChannelEntry in the server to support
5639 the new ban and invite lists.
5641 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Redefined the INVITE command. The same command can be used to
5644 invite individuals to the channel but also to manage the invite
5645 list of the channel (to add to and remove from the invite list).
5646 Updated the protocol specs.
5648 * Added new command SILC_COMMAND_BAN that can be used to manage
5649 the ban list of the channel. Updated the protocol specs.
5651 * Removed the channel modes: the SILC_CMODE_BAN and the
5652 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5653 in the CMODE command. The equivalent features are now available
5654 using INVITE and BAN commands. Updated the protocol specs.
5656 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5657 in the network about change in the current ban list. The notify
5658 type is not used by the client.
5660 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5661 support the invite lists.
5663 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5665 * Added new function silc_string_regexify that converts string
5666 including wildcard characters into regex string that can
5667 be used by the GNU regex library. Added into the file
5668 lib/silcutil/silcutil.[ch].
5670 Added silc_string_regex_combine to combine to regex strings
5671 into one so that they can be used as one regex string by
5672 the GNU regex library. Added into the file
5673 lib/silcutil/silcutil.[ch].
5675 Added silc_string_regex_match to match two strings. It returns
5676 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5678 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Imported GNU regex to the soruce tree into lib/contrib.
5681 Fixed some compiler warning from the regex.c.
5683 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Fixed MOTD command in the server to work in router environment.
5687 * Fixed the MOTD command in the client library to support
5688 the server argument in the command.
5690 * Added `nickname_len' argument to the silc_idlist_add_client
5691 in the server, as the `nickname' argument may be binary data
5694 * Added silc_idlist_get_channels to return all channels from
5697 * Implemented LIST command to the server. Affected file is
5700 * Implemented the LIST command to the client library and on the
5703 * Added [<user count>] argument to the LIST command reply.
5704 With private channels the user count is not shown.
5706 * Updated TODO and README.
5708 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * The client entry's data.registered must be TRUE even with
5711 global client entry on global client list. The data.registered
5712 is used to check whether the client is anymore in the network,
5713 for example with WHOWAS command so it must be valid.
5715 * Fixed the WHOWAS command in the server. It now actually works
5716 in router environment. Added function into silcd/command_reply.c
5717 silc_server_command_reply_whowas_save.
5719 * Added silc_idlist_purge function to the silcd/idlist.c
5720 to periodically purge the ID Cache.
5722 * Fixed INFO command in the server. It works now in router
5723 environment. Added <server name> argument to the INFO command
5724 reply. Updated the protocol specs.
5726 * Fixed minor bug in silc_idcache_purge to not purge if the
5727 expire value is zero.
5729 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5730 they were buggy because of the WHOWAS information.
5732 * Fixed local command MSG to handle the async resolving of
5733 the remote client properly. It used to fail the first MSG.
5734 Affected file silc/local_command.c.
5736 * Added `data_len' field to SilcIDCache context.
5738 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Update TODO. Todo in commands in the server.
5742 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5745 used by routers as broadcast packet to inform other routers
5746 about the changed user mode.
5748 Implemented the notify handling in the server. Affected file is
5749 silcd/packet_receive.c. Added the function
5750 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5752 * Added new generic Channel Payload and deprecated the New Channel
5753 Payload. The New Channel Payload is now the generic Channel
5756 * Added new argument `mode' to the silc_server_send_new_channel
5757 as it is required in the Channel Payload now.
5759 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5760 and created a new and real SilChannelPayload to represent the
5761 new generic Channel Payload. Implemented the encode/decode
5762 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5764 * Added silc_server_get_client_channel_list to return the list
5765 of channels the client has joined for WHOIS command reply.
5766 Affected file silcd/server.[ch].
5768 * Implemented the channel list sending in the WHOIS command reply
5769 in server and in the client.
5771 Implemented the channel list displaying on the user interface
5772 as well. Affected file silc/client_ops.c.
5774 * Added silc_channel_payload_parse_list to parse list of Channel
5775 Payloads. It returns SilcDList list of SilcChannelPayloads.
5776 Client for example can use this function to parse the list of
5777 channels it receives in the WHOIS command reply. The caller
5778 must free the list by calling silc_channel_payload_list_free.
5779 Affected files lib/silccore/silcchannel.[ch].
5781 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Added one new argument <user mode> to the WHOIS command reply
5784 to return the mode of the user in SILC. Updated the protocol
5787 Implemented it to the server and client.
5789 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Fixed the mode printing on the user interface on joining.
5792 Affected file silc/client_ops.c.
5794 * Implemented the UMODE command and user modes in general to the
5795 client library and to the user interface.
5797 * Implemented the UMODE command to the server.
5799 * The server now sends UNKNOWN_COMMAND error status if client sends
5800 unknown command. Affected file silcd/command.c.
5802 * All server commands now handle the command identifier the right
5803 way when sending the command reply to the client. The client can
5804 use to identify the command replies with the identifier.
5806 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Added silc_server_get_client_route to resolve the route to
5809 the client indicated by the client ID. Affected file is
5812 * Added silc_server_relay_packet as general function to relay
5813 packet to arbitrary destination. This deprecates functions
5814 like _send_private_message_key, _relay_notify etc. Affected
5815 file is silcd/packet_send.[ch].
5817 Removed silc_server_send_key_agreement,
5818 silc_server_send_private_message_key and
5819 silc_server_packet_relay_notify functions from the file
5820 silcd/packet_send.[ch].
5824 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5825 server. Affected file silcd/packet_receive.[ch].
5827 * Implemented the KILL command to the client. Implemented the
5828 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5829 Affected files lib/silcclient/command[_reply].c and
5830 lib/silcclient/client_notify.c. Implemented the KILL notify
5831 printing in the user inteface.
5833 * Fixed a lot silc_parse_nick memory leaks from the client
5834 library in the file lib/silcclient/command.c.
5836 * Changed the silc_server_send_notify_on_channels's `sender'
5837 argument from SilcSocketConnection to SilcClientEntry to
5838 check the sender as entry and not as connection object and not
5839 to send to the client provided as argument. The affected file
5840 is silcd/packet_send.[ch].
5842 * The notify packets that are destined directly to the client used
5843 to not to be processed by the server. Now changed that and the
5844 server processes all notify packets. After relaying the packet
5845 to the client the notify packet is processed in the server.
5847 * The silc_server_free_client_data now checks whether there is
5848 pending outgoing traffic for the client and purges the data to
5849 the network before removing the client entry.
5851 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5854 an client is killed from the SILC Network. Updated the protocol
5857 Added new function silc_server_send_notify_killed to the
5858 silcd/packet_send.[ch].
5860 * Added function silc_server_packet_relay_notify to relay notify
5861 packets that are destined directly to a client. In this case
5862 the server does not process the notify packets but merely relays
5863 it to the client. Affected file silcd/packet_send.[ch].
5865 Added also silc_server_packet_process_relay_notify to check
5866 whereto relay the notify. Affected file is
5867 silcd/packet_receive.[ch].
5869 * Implemented the KILL command to the server.
5873 * Added the backup schema desgined last fall to the protocol
5874 specs for everyone to see. The specification is in the
5875 *-spec-xx.txt draft and the packet type definitions for the
5876 backup routers is in *-pp-xx.txt draft. Thusly, added also
5877 new packet type SILC_PACKET_CELL_ROUTERS.
5879 * A big security problem in the implementation discovered. The
5880 signoff of an client did not cause new channel key generation
5881 which it of course should've done. The channel keys must be
5882 always re-generated when client leaves (or signoffs) the channel.
5883 The silc_server_remove_from_channels funtion now handles
5884 the channel key re-generation.
5886 * Added `sender' argument to the silc_server_send_notify_on_channels
5887 to not to send the client provided as argument. Affected file
5888 silcd/packet_send.[ch].
5890 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Implemented OPER and SILCOPER commands into the server and
5895 * Added silc_auth_verify and silc_auth_verify_data to verify
5896 the authentication directly from the authentication payload.
5897 It supports verifying both passphrase and public key based
5898 authentication. Affected file lib/silccore/silcauth.[ch].
5900 * Added `hash' field to the SilcIDListData structure. It is the
5901 hash negotiated in the SKE protocol. Affected file is
5904 * Slight redesigning of the SilcAuthPayload handling routines.
5905 Do not send SilcPKCS but SilcPublicKey as argument.
5907 * Implemented the public key authentication support to the
5908 serverconfig. The public key is loaded from the provided path
5909 and saved as authentication data to void * pointer. Thus,
5910 changed the unsigned char *auth_data to void *auth_data;
5912 * Fixed SHUTDOWN command to send the reply before the server
5913 is shutdown. :) Affected file silcd/command.c.
5915 * Fixed fatal bug in CONNECT command. The hostname was invalid
5916 memory and server crashed. Affected file silcd/command.c.
5918 * Fixed fatal bug in CLOSE command. The server_entry became
5919 invalid but was referenced later in the command. Affected file
5922 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Fixed fatal bug in failure packet handling. Server ignored
5925 the failure and thus crashed when it came.
5929 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5931 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5932 that the command may be executed only once in (about) 2 seconds.
5933 The old SILC_CF_LAG flag is same but allows command bursts up
5934 to five before limiting.
5936 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5937 server code. Various commands now includes the CF_LAG_STRICT
5938 flag to disallow any kind of miss-use of the command.
5940 * Fixed the silc_buffer_unformat to not to allocate any data
5941 if the length of the data is zero. It used to allocate the
5942 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5944 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Changed the format of AdminConnection configuration section
5947 in the server. Added username of the admin to the format.
5948 Affected files silcd/serverconfig.[ch].
5950 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5951 to return admin configuration data by host, username and/or
5954 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Implemented WHOWAS command to the server. Added the functions:
5958 silc_server_command_whowas_parse,
5959 silc_server_command_whowas_send_reply,
5960 silc_server_command_whowas_from_client and
5961 silc_server_command_whowas_from_server
5963 * Added <Client ID> argument to the WHOWAS command reply. Updated
5964 the protocol specs accordingly.
5966 * Implemented WHOWAS command and command_reply to the client
5969 Implemented the WHOWAS printing on the user interface.
5971 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added new argument to the WHOWAS command reply, the real name.
5974 It is an optional argument. Updated the protocol specs.
5976 * Added SilcIDCacheDestructor callback that is registered when
5977 the SilcIDCache is allocated. The callback is called when
5978 an cache entry in the ID Cache expires, or is purged from the
5979 cache. Added into lib/silccore/idcache.[ch].
5981 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5982 to destruct the client entries when the cache entry expires.
5983 Other ID Cache's in server and in the client library ignores
5986 * If the ID Cache entry's `expire' field is zero then the entry
5987 never expires. Added boolean `expire' argument to the
5988 silc_idcache_add function in the lib/silccore/idcache.[ch].
5989 If it is TRUE the default expiry value is used.
5991 * Added silc_server_free_client_data_timeout that is registered
5992 when client disconnects. By default for 5 minutes we preserve
5993 the client entry for history - for WHOWAS command.
5995 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Added support to the server to enforce that commands are not
5998 executed more than once in 2 seconds. If server receives
5999 commands from client more frequently, timeout is registered
6000 to process the commands. Affected file silcd/command.c.
6001 Added new function silc_server_command_process_timeout.
6003 * Changed NICK_NOTIFY handling in client library to check that
6004 if the client's nickname was changed, so there is no need to
6005 resolve anything from the server.
6007 * Removed error printing from the WHOIS and IDENTIFY commands.
6008 If error occurs then it is ignored silently in the client library.
6009 The application, however, may map the received error to
6010 human readable error string. The application currently maps
6011 the NO_SUCH_NICKNAME error to string.
6013 * Made the command status message public to the application. Moved
6014 them from lib/silcclient/command_reply.c to
6015 lib/silcclient/command_reply.h. The application can map the
6016 received command status to the string with the
6017 silc_client_command_status_message function.
6019 * Added check to the server to check that client's ID is same
6020 as the Source ID in the packet the client sent. They must
6023 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Added dist-bzip hook to the Makefile.am to make bzip2
6026 compressed distributions.
6028 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6030 * Server now enforces the maximum length for the nickname and
6031 the channel as protocol specification dictates. 128 bytes for
6032 nickname and 256 bytes for channel name.
6034 * Moved the WHOIS printing to the application. The client libary
6035 does not print out the WHOIS information anymore, the application
6036 must do it. Renamed silc_client_command_reply_whois_print to
6037 the silc_client_command_reply_whois_save.
6039 The client's idle time is also sent to the application now, and
6040 the idle is shown on screen.
6042 * Added silc_client_command_reply_identify_save to save the
6043 received IDENTIFY entries.
6045 * Do not check for channel private keys in message sending and
6046 reception if the channel does not have the PRIVKEY mode set.
6047 Affected file lib/silclient/client_channel.c.
6049 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6052 just surfaced after chaning the JOIN procedure.
6054 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6056 * Added silc_client_get_clients_by_list to get client entries
6057 from Client ID list, that is returned for example by JOIN
6058 and USERS command replies. The application should use this
6059 function for example when JOIN command reply is received to
6060 resolve the clients already on the channel (library does not
6061 do that anymore as USERS command reply is not used in the JOIN
6062 procedure anymore). Affected files lib/silcclient/silcapi.h and
6063 lib/silcclient/idlist.c.
6065 * JOIN command reply and USERS command reply returns now SilcBuffer
6066 pointers instead of unsigned char pointers when returning
6067 the client list and mode list.
6069 * Added <Client ID> argument to the JOIN command reply, mainly
6070 for the server to identify for which client the command was
6071 originally sent. Updated protocol specs accordingly.
6073 * Added SilcDlist private_key pointer to the SilcChannelEntry
6074 in the client to support the channel private keys. Affected
6075 file is lib/silcclient/idlist.h.
6077 * Added SilcChannelPrivateKey argument to the function
6078 silc_client_send_channel_message so that application can choose
6079 to use specific private ke if it wants to. If it is not provided,
6080 the normal channel key is used, unless private keys are set.
6081 In this case the first (key that was added first) is used
6082 as the encryption key.
6084 * Implemented the support for channel private key handling.
6085 Implemented the following functions:
6087 silc_client_add_channel_private_key,
6088 silc_client_del_channel_private_keys,
6089 silc_client_del_channel_private_key,
6090 silc_client_list_channel_private_keys and
6091 silc_client_free_channel_private_keys
6093 Affected file lib/silcclient/client_channel.c.
6095 * Added the support for the private keys in the channel message
6096 sending and encryption and in the message reception and
6097 decryption. Affected funtions are
6098 silc_client_send_channel_message and silc_client_channel_message.
6100 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Added SKE's key verify callback to the client library's
6103 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6105 * Removed the statement that server (or router) must send USERS
6106 command reply when joining to the channel so that the client
6107 knows who are on the channel. Instead, the client list and
6108 client's mode list is now sent in the JOIN command reply to the
6109 client who joined channel. This is better solution.
6111 * Added function silc_server_get_users_on_channel and function
6112 silc_server_save_users_on_channel to the silcd/server.[ch].
6114 * Removed function silc_server_command_send_users from the
6117 * Do not show topic on the client library anymore. The topic is
6118 sent in the command reply notify to the application and the
6119 application must show the topic now.
6121 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Added client searching by nickname hash into the IDENTIFY and
6124 WHOIS commands in the server as they were clearly missing from
6125 them. Affected file is silcd/command.c.
6127 * Fixed a bug in private message receiving in the client library.
6128 The remote ID was freed and it wasn't supposed, now it is
6131 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6133 * Minor fix to the channel payload; allocate the data area, as it
6134 needs to be of specific length.
6136 * If the key agreement port is zero then the operating
6137 system will define the bound port. Affected files are
6138 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6140 * Added new function silc_channel_payload_decrypt into the file
6141 lib/silccore/silcchannel.[ch].
6143 * Moved the channel message etc, check from silc_packet_decrypt
6144 to applications. The library calls now a generic
6145 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6146 when the packet is either normal or special. This was done to
6147 allow more wide range of checking that was not allowed when
6148 the code was in library. Now applications can do virtually any
6149 checks to the packet and return to the library the decision how
6150 the packet should be processed. Affected files are
6151 lib/silccore/silcpacket.[ch].
6153 Added silc_server_packet_decrypt_check to the server and
6154 silc_client_packet_decrypt_check to the client library.
6156 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6157 to send with specified source and destination information.
6159 * Channel message delivery between routers was broken after the
6160 channel key distribution was fixed earlier. The channel key
6161 was used be to distributed to other routers as well which is not
6162 allowed by the protocol. Now this is fixed and channel keys
6163 really are cell specific and the channel message delivery between
6164 routers comply with the protocol specification.
6166 * Fixed various commands in server to check also the global list
6167 for the channel entry and not just the local list. The affected
6168 file silcd/command.c.
6170 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Added assert()s to buffer formatting and unformatting routines
6173 to assert (if --enable-debug) when error occurs. Affected
6174 file: lib/silcutil/silcbuffmt.c.
6176 * Changed to auto-reconnect to check whether the remote host is
6177 router and register the re-connect timeout if it is. It used
6178 to check that whether we are normal server, but router must do
6179 auto-reconnect with another router as well. Affected file
6182 * Removed the [<key len>] option from CMODE command as the cipher
6183 name decides the key length, nowadays. See the defined ciphers
6184 from the protocol specification.
6186 * Added [<hmac>] option to the CMODE command to define the HMAC
6187 for the channel. Added SILC_CMODE_HMAC channel mode.
6189 * Added [<hmac>] option for the JOIN command so that user can
6190 select which HMAC is used to compute the MACs of the channel
6193 * Added Hmac field to the Channel Message Payload. The integrity
6194 of plaintext channel messages are now protected by computing
6195 MAC of the message and attaching the MAC to the payload. The
6196 MAC is encrypted. Now, it is clear that this causes some
6197 overhead to the size of the packet but rationale for this is that
6198 now the receiver can verify whether the channel message decrypted
6199 correctly and also when private keys are set for the channel the
6200 receiver can decrypt the packet with several keys and check from
6201 the MAC which key decrypted the message correctly.
6203 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6204 lib/silccrypt/silccipher.[ch].
6206 * Added silc_hash_len to return the digest length into the
6207 lib/silcrypt/silchash.[ch].
6209 * Rewrote parts of Silc Channel Payload interface in the
6210 lib/silccore/silcchannel.[ch]. The encode function now also
6211 encrypts the packet and parse function decrypts it.
6213 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6215 * Fixed a minor formatting bug in the SKE's key material processing.
6216 It actually might have processed the keys wrong way resulting
6219 * Redefined the mandatory HMAC algorithms and added new algorithms.
6220 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6221 and hmac-md5 truncated to 96 bits. The mandatory is now
6222 hmac-sha1-96. Rest are optional (including the one that used
6223 to be mandatory). Rationale for this is that the truncated HMAC
6224 length is sufficient from security point of view and can actually
6225 make the attack against the HMAC harder. Also, the truncated
6226 HMAC causes less overhead to the packets. See the RFC2104 for
6229 * Added new [hmac] configuration section. The SKE used to use
6230 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6231 is of course wrong. The official names that must be proposed in
6232 the SKE are the ones defined in the protocol specification
6233 (hmac-sha1-96 for example). The user can configure any hmac
6234 using any hash function configured in the [hash] section. At
6235 least, the mandatory must be configured.
6237 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6239 * Added HMAC list to the SKE proposal list. It has now both
6240 hash algorithm list and HMAC list. This makes the protocol
6241 incompatible with previous versions. The SKE now seems to work
6242 the way it is supposed to work, for the first time actually.
6244 * Defined plain Hash algorithms to the protocol specification.
6247 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Implemented support for key agreement packets into the server.
6250 Added functions silc_server_key_agreement and
6251 silc_server_send_key_agreement. Other than these functions,
6252 server has nothing to do with this packet.
6254 * Added support for private message key packets into the server.
6255 Added functions silc_server_private_message_key and
6256 silc_server_send_private_message_key.
6260 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6261 called in the protocol's final callback instead in the END
6262 protocol state. This makes a little more sense and in the same
6263 time in client we can use the same protocol routines for normal
6264 key exchange and to key agreement packet handling as well.
6266 * Added to both client's and server's KE protocol context the
6267 SilcSKEKeyMaterial pointer to save the key material. We will
6268 bring the key material to the protocol's final callback by doing
6269 this. The final callback must free the key material.
6271 * Added SKE's packet_send callback into client's KE protocol
6272 context so that the caller can choose what packet sending function
6273 is used. This way we can use different packet sending when
6274 doing normal SKE when doing key agreement packet handling (in
6275 the key agreement packet handling we do not want to encrypt
6278 * Implemented the responder side of the key agreement routines
6279 in the client. The client can now bind to specified port and
6280 accept incoming key negotiation. The key material is passed
6281 to the application after the protocol is over.
6283 * Implemented the processing of incoming Key Agreement packet
6284 in the client. Added function silc_client_key_agreement to
6287 * Implemented the intiator side of the key agreement routines
6288 in the client. The client can now initiate key agreement with
6289 another remote client. The key material is passed to the
6290 application after the protocol is over.
6292 * Created client_keyagr.c to include all the key agreement
6295 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6296 SILC_TASK_CALLBACK except that it is not static.
6298 * Created client_notify.c and moved the Notify packet handling
6299 from the client.[ch] into that file.
6301 * Created client_prvmsg.c and moved all private message and
6302 private message key routines from the client.[ch] into that file.
6304 * Create client_channel.c and moved all channel message and
6305 channel private key routines from the client.[ch] into that file.
6307 * Changed silc_client_get_client_by_id_resolve to resolve with
6308 WHOIS command instead of IDENTIFY command, in the file
6309 lib/silclient/idlist.c.
6311 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Implemented the SKE's responder side to the Client library.
6315 * When FAILURE is received to the protocol do not trust it
6316 blindly. Register a timeout to wait whether the remote closes
6317 the connection as it should do it, only after that process the
6318 actual failure. This was changed to both client and server.
6320 * Added client_internal.h to include some of the structures
6321 there instead of client.h in lib/silcclient/.
6323 * Added function silc_task_unregister_by_callback to unregister
6324 timeouts by the callback function.
6326 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Some "Incomplete WHOIS info" errors has been appearing on the
6329 log files. Took away the entry->userinfo check from WHOIS
6330 reply sending. The entry->userinfo is now " " if client did not
6331 provide one. I thought this was fixed earlier but something
6332 is wrong still. Let's see if the error still appears.
6334 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Fixed a minor bug in the login when the channel key is
6337 re-generated in the server. It used to generate the key in
6338 wrong order and thus caused problems in the channel traffic.
6340 * Fixed a minor bug in channel key distsribution after
6341 KICK command. The key was not sent to the router even though
6344 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6346 * Added silc_ske_process_key_material_data as generic routine
6347 to process any key material as the SILC protocol dictates. The
6348 function is used by the actual SKE library but can be used by
6349 applications as well. This relates to the private message keys
6350 and the channel private keys since they must be processed the
6351 same way the normal SILC session keys. The protocol dictates
6352 this. Affected files: lib/silcske/silcske.[ch].
6354 Added also silc_ske_free_key_material to free the
6355 SilcSKEKeyMaterial structure.
6357 * Defined silc_cipher_set_key function to set the key for
6358 cipher without using the object's method function. The affected
6359 files: lib/silccrypt/silccipher.[ch].
6361 * Implemented silc silc_client_add_private_message_key,
6362 silc_client_add_private_message_key_ske,
6363 silc_client_del_private_message_key,
6364 silc_client_list_private_message_keys and
6365 silc_client_free_private_message_keys functions in the
6368 Added functions silc_client_send_private_message_key to send
6369 the Private Message Key payload and silc_client_private_message_key
6370 to handle incoming Private Message Key payload.
6372 * Added Cipher field to the Private Message Key payload to set
6373 the cipher to be used. If ignored, the default cipher defined
6374 in the SILC protocol (aes-256-cbc) is used.
6376 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6378 * Removed lib/silcclient/ops.h file.
6380 Redefined parts of the SILC Client Library API. Created new
6381 file silcapi.h that deprecates the ops.h file and defines the
6382 published Client Library API. Defined also private message key
6383 API and channel private key API into the file.
6385 This is the file that the application must include from the
6386 SILC Client Library. Other files need not be included by
6387 the application anymore.
6389 * Added new key_agreement client operation callback and also
6390 defined the Key Agreement library API for the application.
6392 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6395 is used by clients to request key negotiation between another
6396 client in the SILC network. If the negotiation is started it
6397 is performed using the SKE protocol. The result of the
6398 negotiation, the secret key material, can be used for example
6399 as private message key.
6401 Implemented the Key Agreement payload into the files
6402 lib/silccore/silauth.[ch].
6404 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Redefined ciphers for the SILC protocol. Added some new ciphers
6407 and defined the key lengths for the algorithms. Changed the
6408 code accordingly. The default key length is now 256 bits.
6410 * Fixed SKE key distribution function silc_ske_process_key_material
6411 when the key length is more than 128 bits. The default key
6412 length in SILC is now 256 bits.
6414 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6415 to indicate unsupported algorithm.
6417 * Renamed rijndael.c to aes.c and all functions as well.
6419 * Fixed a long standing channel key setting bug in client library.
6420 Weird that it has never surfaced before.
6422 * Fixed bug in channel deletion. If the entire channel is removed
6423 then it must also delete the references of the channel entry
6424 from the client's channel list as the client's channel entry and
6425 the channel's client entry share same memory.
6427 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6429 * Implemented CONNECT and SHUTDOWN commands in the client.
6431 * Implemented CLOSE command to the client.
6433 * Added the function silc_idlist_find_server_by_name into the
6434 files silcd/idlist.[ch].
6436 Added the function silc_idlist_find_server_by_conn into the
6437 files silcd/idlist.[ch].
6439 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * DIE command was renamed to SHUTDOWN. Updated the both code
6444 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6445 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6447 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6450 * Added function silc_server_create_connection function to create
6451 connection to remote router. My server implementation actually
6452 does not allow router to connect to normal server (it expects
6453 that normal server always initiates the connection to the router)
6454 so the CONNECT command is only good for connecting to another
6457 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6459 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6460 or some other client was kicked from the channel.
6462 Implemented the handling of the notify type to both client
6465 Implemented silc_server_send_notify_kicked to send the KICKED
6466 notify. It is used to send it to the server's primary router.
6468 * Implemented the KICK command into server and client.
6470 * Added `query' argument to the silc_idlist_get_client function
6471 to indicate whether to query the client from server or not if
6474 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6475 to indicate that the client is not channel founder.
6479 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6481 * Removed the rng context from SilcPacketContext structure and
6482 changed that the packet routine uses the Global RNG API.
6484 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * Added support for quit message that client can "leave" on the
6487 channel when it quits the SILC. It is ditributed inside the
6488 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6490 Added silc_server_free_client_data that will take the
6491 signoff message as argument.
6493 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6495 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Updated parts of the protocol specification to keep it up
6500 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6503 payloads in one packet.
6505 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6506 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6507 use now the new List flag.
6509 * Also deprecated the following packet types: REPLACE_ID,
6510 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6512 * Added list support for Notify packet in server.
6514 * Added silc_server_send_notify_channel_change to send the
6515 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6516 the silc_server_send_replace_id.
6518 * Added silc_server_send_notify_nick_change to send the
6519 NICK_CHANGE notify type. Deprecates the function
6520 silc_server_send_replace_id.
6522 * Added silc_server_send_notify_join to send the JOIN notify type.
6523 Deprecates the function silc_server_send_new_channel_user.
6525 * Added silc_server_send_notify_leave to send LEAVE notify type.
6526 Deprecates the function silc_server_send_remove_channel_user.
6528 * Added silc_server_send_notify_cmode and
6529 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6530 types. Deprecates the silc_server_send_set_mode function.
6532 * Added SERVER_SIGNOFF notify type to indicate that server has
6533 quit. This means that all clients on the channel from that
6534 server will drop. This can be also used when netsplit happens.
6536 Deprecated REMOVE_ID packet type since it is not needed anymore
6539 Added silc_server_send_notify_server_signoff to send the
6540 SERVER_SIGNOFF notify type. Deprecates the function
6541 silc_server_send_remove_id.
6543 Added also silc_server_send_notify_signoff to send the
6544 SIGNOFF notify type.
6546 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6547 SILC protocol from this day on. Changed the protocol
6548 specification as well.
6550 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6551 notify type. It is used between routers to notify about
6552 topic changes on a channel.
6554 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6557 * Partly updated the protocol specification to comply with the
6558 changes now made. It is still though a bit outdated.
6560 * The JOIN notify type now takes one extra argument <Channel ID>.
6561 The packet used to be destined to the channel but now the
6562 JOIN type may be sent as list thus it is impossible to
6563 destine it to any specific channel. By adding this argument
6564 it is again possible.
6566 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Added CREDITS file. The CHANGES and CREDITS file will appear
6569 in the distribution as well.
6571 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6574 types in the server's silcd/packet_receive.c.
6576 * Implemented CMODE and CUMODE to work in router environment.
6578 * Fixed minor encoding and decoding buglet from the
6579 lib/silccore/silcmode.c.
6581 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6584 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6586 * Changed all SilcConfigServer* and silc_config_server* to
6587 SilcServerConfig* and silc_server_config*, respectively.
6590 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Associated the ID (client or server ID) to the Authentication
6593 Payload to avoid any possibility of forging. Updated the
6594 protocol specification and the code accordingly.
6596 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * The RSA key length is now save to the RsaKey context in the
6599 key generation process in lib/silccrypt/rsa.c. The key length
6600 is now used to figure out the maximum size of the block allowed
6601 to be encrypted/signed.
6603 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6604 is equivalent to the silc_mp_mp2bin but does not allocate any
6607 * Changed silc_mp_mp2bin API to take length argument. If it is
6608 non-zero then the buffer is allocated that large. If zero, then
6609 the size is approximated using silc_mp_sizeinbase, which however
6612 * Created Global RNG API which is global RNG that application can
6613 initialize. After initializing, any routine anywhere in the
6614 code (including library) can use RNG without allocating a new
6615 RNG object. This was done to allow this sort of use of the
6616 RNG in code that has no chance to allocate RNG object. All
6617 applications currently allocate this and many routines in the
6618 library use this. Affected file lib/silccrypt/silcrng.[ch].
6620 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6621 it to use the Global RNG API.
6623 * Defined Authentication Payload into protocol specification that
6624 is used during SILC session to authenticate entities. It is
6625 used for example by client to authenticate itself to the server
6626 to obtain server operator privileges.
6628 Implemented this payload into the lib/silccore/silcauth.[ch].
6629 Implemented also routines for public key based authentication
6630 as the new protocol specification dictates.
6632 Moved definitions of different authentication methods from
6633 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6635 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6636 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6637 silc_pkcs_verify_with_hash functions into the file
6638 lib/silccrypt/silcpkcs.[ch].
6640 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * The client entry's userinfo pointer must be always valid.
6643 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6644 will fail since it requires the userinfo. Now, the userinfo
6645 is allocated as "" if actual userinfo does not exist. Actually,
6646 it must exist and it is totally Ok to drop client connections
6647 that does not announce the userinfo. However, we will make
6648 this workaround for now.
6650 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6651 to return the remote port by socket.
6653 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6656 SILC_SERVER_PENDING_EXEC and added an new macro
6657 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6658 data or when error occurs while processing the pending command.
6660 Added new argument `destructor' into silc_server_command_pending
6661 and to the SilcServerCommandPending object. This destructor is
6662 now called after calling the pending callback or if error occurs
6663 immediately. If error occurs the actual pending callback won't
6664 be called at all - only the destructor. The destructor may be
6665 NULL if destructor is not needed.
6667 All this applies for client library code as well. Similar
6668 changes were made there as well for the pending commands.
6670 In the client, the application must now allocate the
6671 SilcClientCommandContext with the silc_client_command_alloc
6674 * Added reference counter to the SilcServerCommandContext. Added
6675 function silc_server_command_alloc and silc_server_command_dup
6678 Same type of functions added to the client library for the same
6681 * Removed the cmd_ident from IDListData away since it is now
6682 global for all connections. It is the command identifier used
6683 in command sending and with pending commands. The affected file
6686 * Added reference counter to the SilcSocketConnection objecet to
6687 indicate the usage count of the object. The object won't be
6688 freed untill the reference counter hits zero. Currently only
6689 server uses this, and client ignores it. The client must be
6690 set to use this too later. The affected files are
6691 lib/silccore/silcsockconn.[ch]. Added also the function
6692 silc_socket_dup to increase the reference counter.
6694 This was mainly added because it is possible that the socket
6695 is removed underneath of pending command or other async
6696 operation. Now it won't be free'd and proper DISCONNECTING
6697 flags, etc. can be set to avoid sending data to connection that
6698 is not valid anymore.
6700 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6701 the connection. After that it sets SILC_SET_DISCONNECTED.
6702 It is, however, possible that the socket data is not still freed.
6703 The silc_server_packet_process now checks that data is not
6704 read or written to connection that is DISCONNECTED. The socket
6705 get's freed when the reference counter hits zero.
6707 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6709 * Changed the client operation API: channel_message operation's
6710 `sender' is now the client entry of the sender, not the nickname
6711 and the `channel' is the channel entry, not the channel name.
6713 In the private_message operation the `sender' is now also the
6714 client entry of the sender not the nickname.
6716 Affected file is lib/silcclient/ops.h and all applications
6717 using the client operations.
6719 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * Moved the calling of ops->connect() from connect_to_server_final
6722 into receive_new_id functin since that is the point when the
6723 client is actually allowed to send traffic to network. The
6724 affected file is lib/silcclient/client.c.
6726 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6728 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6729 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6730 (if needs broadcasting) instead of broadcasting the packets one
6731 by one which would make a burst in the network traffic.
6733 * Added `broadcast' argument to the functions in silcd/server.[ch]
6734 silc_server_create_new_channel[_with_id] to indicate whether
6735 to send New Channel packet to primary router.
6737 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Added new function into the silcd/server.[ch] files:
6740 silc_server_create_new_channel_with_id to create new channel with
6741 already existing Channel ID.
6743 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6744 lib/silccore/silcpacket.h. This packet is used t send list of
6745 Set Mode payloads inside one packet. Server uses this to set
6746 the modes for the channels and clients on those channels, that it
6747 announced to the router when it connected to it. The protocol
6748 specification has been updated accordingly.
6750 * The silc_server_new_channel did not handle the packet coming
6751 from normal server as it normally does not send that. However,
6752 when it announces its channels it does send it. Implemented
6753 the support for that.
6755 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6756 into the file lib/silccore/id.h.
6758 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Fixed memory leaks in the functions silc_idlist_del_client,
6761 silc_idlist_del_channel and silc_idlist_del_server in the file
6762 silcd/idlist.c. All of those leaked like a sieve.
6764 * Fixed some small memory leaks in the client's function
6765 silc_client_notify_by_server.
6767 * Added functions into silcd/server.c: silc_server_announce_clients,
6768 silc_server_announce_channels and silc_server_announce_server.
6769 These functions are used by normal and router server to announce
6770 to its primary router about clients, channels and servers (when
6771 router) that we own. This is done after we've connected to the
6774 These functions effectively implements the following packet types:
6775 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6776 and SILC_PACKET_NEW_ID_LIST.
6778 * Added new functions into the silcd/packet_receive.[ch]:
6779 silc_server_new_id_list, silc_server_new_channel_list and
6780 silc_server_new_channel_user_list to handle the incoming
6781 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6783 * Added support of changing Channel ID in the function
6784 silc_server_replace_id. If the server that announces a channel
6785 to the router already exists in the router (with same name but
6786 with different Channel ID), router is responsible to send
6787 Replace ID packet to the server and force the server to change
6788 the Channel ID to the one router has.
6790 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6791 client that the Channel ID has been changed by the router. The
6792 normal server sends this to the client. Client must start using
6793 the new Channel ID as the channel's ID.
6795 Implemented handling of this new type into lib/silcclient/client.c
6796 into the function silc_client_notify_by_server.
6798 * Added new function silc_idlist_replace_channel_id into the files
6799 silcd/idlist.[ch] to replace the Channel ID.
6801 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Call silc_server_command_identify_check always when processing
6804 the IDENTIFY command in silcd/command.c
6806 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6809 send keepalive packets. The packet can be sent by clients,
6810 servers and routers.
6812 Added function silc_socket_set_heartbeat into the file
6813 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6814 If not set, the heartbeat is not performed. The actual
6815 heartbeat is implemented in the low level socket connection
6816 library. However, application is responsible of actually
6819 Added silc_server_send_heartbeat to send the actual heartbeat
6820 packet into silcd/packet_send.[ch]. Server now performs
6821 keepalive with all connections.
6823 * Added silc_task_get_first function into lib/silcutil/silctask.c
6824 to return the timeout task with shortest timeout. There was a bug
6825 in task unregistration that caused problems. TODO has been
6826 updated to include that task system must be rewritten.
6828 * The client library will now resolve the client information when
6829 receiving JOIN notify from server for client that we know but
6830 have incomplete information.
6832 * Rewrote parts of silc_server_remove_from_channels and
6833 silc_server_remove_from_one_channel as they did not remove the
6834 channel in some circumstances even though they should've.
6836 * Encryption problem encountered in server:
6838 The LEAVE command used to send the Channel Key packet to the
6839 router immediately after generating it. However, the code
6840 had earlier sent Remove Channel user packet but not immediately,
6841 ie. it was put to queue. The order of packets in the router
6842 was that Channel Key packet was first and Remove Channel User
6843 packet was second, even though they were encrypted in the
6844 reverse order. For this reason, MAC check failed. Now, this
6845 is fixed by not sending the Channel Key packet immediately but
6846 putting it to queue. However, this is more fundamental problem:
6847 packets that are in queue should actually not be encrypted
6848 because packets that are sent immediately gets encrypted
6849 actually with wrong IV (and thus MAC check fails). So, packets
6850 that are in queue should be encrypted when they are sent to
6851 the wire and not when they put to the queue.
6853 However, the problem is that the current system has not been
6854 designed to work that way. Instead, the packet is encrypted
6855 as soon as possible and left to the queue. The queue is then
6856 just purged into wire. There won't be any fixes for this
6857 any time soon. So, the current semantic for packet sending
6860 o If you send packet to remote host and do not force the send
6861 (the packet will be in queue) then all subsequent packets to the
6862 same remote host must also be put to the queue. Only after the
6863 queue has been purged is it safe again to force the packet
6866 o If you send all packets immediately then it safe to send
6867 any of subsequent packets through the queue, however, after
6868 the first packet is put to queue then any subsequent packets
6869 must also be put to the queue.
6871 Follow these rules and everything works fine.
6873 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Added new function silc_server_remove_clients_by_server to
6876 remove all client entries from ID list when the server connection
6877 is lost. In this case it is also important to invalidate all
6878 client entires as they hold the invalid server entry. This
6879 fixes fatal bug when server has lost connection and will reconnect
6882 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6884 * Made some sanity checks to silc_server_daemonise like to check
6885 whether the requested user and group actually exists.
6887 * Added sanity check to SKE's silc_ske_responder_finish to check
6888 that the public and private key actually is valid.
6890 * Invalidate the client's nickname when receiving Replace ID
6891 packet and the Client ID is being replaced. This means that the
6892 server will query the nickname if someone needs it (client)
6895 * Sort the ID Cache in client library when the ID Cache data
6896 has changed (needs sorting).
6898 * Do not allow for SILC client to create several connections to
6899 several servers. The client does not support windows right now
6900 and generating multiple connections causes weird behaviour.
6902 Irssi-silc client does support windows and can handle several
6903 connections without problems, see: www.irssi.org and SILC plugin.
6905 * Fixed some places where client was added to the IDList. The
6906 rule of thumb is following (in order to get everything right):
6907 If the client is directly connected local client then the
6908 `connection' argument must be set and `router' argument must be
6909 NULL to silc_idlist_add_client function. If the client is not
6910 directly connected client then the `router' argument must
6911 bet set and the `connection' argument must be NULL to the
6912 silc_idlist_add_client function.
6914 * The funtion silc_server_packet_send_local_channel actually did
6915 not check whether the client was locally connected or not. It
6916 does that now. Fixed a bug related to LEAVE command.
6918 * Fixed Remove Channel User payload parsing bug in server's
6919 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6921 * The server's silc_server_save_channel_key now checks also the
6922 global ID list for the channel as it might not be in the local
6923 list. Fixed a bug related to LEAVE command.
6925 * Is this the end of the [<unknown>] buglet that has been lurking
6926 around for a long time? A little for loop fix in server's
6927 silc_server_command_whois_parse that is used by both IDENTIFY
6928 and WHOIS command. At least, this was a clear bug and a cause
6929 of one type of [<unknown>] buglet.
6931 * WHOIS and IDENTIFY commands call the function
6932 silc_server_command_[whois/identify]_check function even if
6933 we are not router server.
6935 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6937 * Added --with-gmp configuration option. If set the GMP
6938 is always compiled in the SILC source tree. If not set then
6939 it is checked whether the system has the GMP3 installed. If
6940 it has then the GMP won't be compiled (the system's headers
6941 and library is used), if it doesn't have it then the GMP is
6942 compiled in the SILC source tree.
6944 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6946 * Changed RSA private exponent generation to what PKCS #1
6947 suggests. We try to find the smallest possible d by doing
6948 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6949 not security fix but optimization.
6951 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6953 * Added new config entry [Identity] to fork the server and run
6954 it as specific user and group. A patch from Bostik.
6956 * Imported Dotconf configuration library into lib/dotconf.
6957 This will be used to create the SILC configuration files later.
6958 It will appear in the distsribution after this commit.
6960 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6962 * A big code auditing weekend happening. Auditing code for
6963 obvious mistakes, bugs and errors. Also, removing any code
6966 Removed files for being obsolete:
6968 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6969 inline in the file lib/silcutil/silcbuffer.h)
6971 o lib/silcutil/silcbufutil.c (the header has inline versions)
6973 Changed code to fix possible error conditions:
6975 o The buffer formatting routines now check that the destination
6976 buffer really has enough space to add the data. This applies for
6977 both buffer formatting and unformatting
6978 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6979 unformatting was changed to accomodate following rules:
6980 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6981 sent to the function while XXX_*STRING will not allocate or copy
6982 the data into the buffer. Instead it sets the pointer from the
6983 buffer into the pointer sent as argument (XXX_*STRING used to
6984 require that the pointer must be allocated already). This change
6985 makes this whole thing a bit more consistent and more optimized
6986 (note that the data returned in the unformatting with XXX_*STRING
6987 must not be freed now). The routines return now -1 on error.
6989 o Tried to find all code that use buffer_format and buffer_unformat
6990 and added return value checking to prevent formatting and
6991 especially unformatting errors and possible subsequent fatal
6994 o Changed ske->x and ske->KEY to mallocated pointers in
6995 lib/silcske/silcske.h. Fixed possible data and memory leak.
6997 o Added return value checking to all *_parse* functions. Fixed
6998 many memory leaks as well.
7000 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7001 so that buffer overflows would not happen. All code now also
7002 checks the return value as it can fail.
7004 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Added reconnection support to server if the normal server looses
7007 its connection to the router (for example if router is rebooted).
7008 The server performs normal reconnection strategy implemented
7009 to the server. Affected file silcd/server.c.
7011 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Added new packet type SILC_PACKET_SET_MODE that is used to
7014 distribute the information about changed modes (for clients,
7015 channels and clients channel modes) to all routers in the
7016 network. Updated the protocol specification accordingly.
7018 Added functions into silcd/packet_send.c and
7019 silcd/packet_receive.c: silc_server_send_set_mode,
7020 silc_server_set_mode.
7022 Added new files silcmode.[ch] into lib/silccore that implements
7023 the encoding and decoding of Set Mode Payload. Added new type
7024 SilcSetModePayload. Moved the definitions of different modes
7025 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7027 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7029 * Oops, a little mistake in server's connection authentication
7030 protocol. The protocol is not ended with FAILURE but with
7031 SUCCESS if the authentication is Ok. :) Affected file is
7034 * Implemented NICK_CHANGE notify handling in server in the file
7035 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7036 the local clients on the channel. After the changing nickname
7037 in router environment snhould work and the [<unknown>] nickname
7038 should appear no more.
7040 The silc_server_replace_id function that receives the Replace ID
7041 payload now sends the NICK_CHANGE notify type also in the file
7042 silcd/packet_receive.c
7044 * Changed WHOIS and IDENTIFY command to support the maximum amount
7045 of arguments defined in protocol specs (3328 arguments). This
7046 fixed a bug that caused problems when there were more than three
7049 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Added extra parameter, command identifier, to the
7052 silc_client_send_command so that explicit command identifier
7055 Changed that ID list routines uses specific command identifier
7056 when sending WHOIS/IDENTIFY requests to the server so that they
7057 can be identified when the reply comes back.
7059 Affected files lib/silcclient/command.[ch],
7060 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7062 * Added `sender' argument to silc_server_packet_send_to_channel
7063 to indicaet the sender who originally sent the packet to us
7064 that we are now re-sending. Ignored if NULL. Affected file
7065 silcd/packet_send.[ch].
7067 * Added some server statistics support in silcd/server_internal.h
7068 SilcServerStatistics structure and around the server code. Also
7069 send some nice statistics information when client is connecting
7072 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Fixed channel ID decoding in server's JOIN command reply in
7075 silcd/command_reply.c
7077 * Fixed braodcasting of replace ID payload to not to send it if
7078 we are standalone server in silcd/packet_receive.c.
7080 * Fixed all channel message sending routines to not to send
7081 packets to clients that has router set, since they are routed
7082 separately in the same function earlier. Affects file
7083 silcd/packet_send.c and all channel packet sending functions.
7085 * In USERS reply, res_argv[i] are not allocated, the table
7086 is allocated. Thus changed that free the table, not its
7089 * In server's whois_check and identify_check if the client is
7090 locally connected do not send any WHOIS commands - they are not
7093 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7095 * Fixed some minor bugs in client when sending WHOIS command. The
7096 arguments was in wrong order.
7098 * Removed statis function add_to_channel from server in
7099 silcd/command.c that was previously used with the joining but
7102 * Tested USERS command in router environment successfully with two
7103 routers, two servers and two clients.
7105 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * Reorganized the USERS command and command reply in client library
7108 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7109 When the command is given by user we register a pending command
7110 callback that will reprocess the command after the reply has been
7111 received from the server. When reprocessing the packet we then
7112 display the information. Thus, the USERS information is displayed
7113 now in the command callback instead of in the command reply
7114 callback. The processing of the command is same as previously
7115 when server has sent the command reply in the JOINing process.
7117 * Added to USERS command in silcd/command_reply.c to join the client,
7118 we didn't use to know about, to the channel after we've created
7119 a client entry for it. Also, for clienet we did know already still
7120 check whether it is on the channel or not and add it if not.
7122 * Removed silc_server_command_join_notify as the function and its
7125 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Changed the client's pending command handling to the same as the
7128 server's pending command handling. It is also now possible to
7129 execute command reply functions from other command reply
7130 function as the function callbacks for commands and command
7131 replies are one and same. The pending commands are not static
7132 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7133 in client connection context. Thus, pending commands are server
7134 connection specific as it is convenient.
7136 Changed the function silc_client_command_pending and
7137 silc_client_command_pending_del and added new function
7138 silc_client_command_pending_check. Removed the
7139 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7142 * Added cmd_ident, current command identifier, to the client
7143 connection context in lib/silcclient/client.h to keep track on
7144 command identifiers used in command sending. Client's command reply
7145 function handling now supports the mandatory command identifiers.
7147 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7148 funtions in client to fully support pending command callbacks.
7150 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7151 as one of the arguments to the application in the command reply
7154 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7155 before first releasing SILC but came back. Now it is removed again
7156 and should come back nomore. The FORWARDED flag was used only
7157 by the JOINing procedure by forwarding the command packet to router.
7158 Now, the JOINing procedure has been changed to more generic (due
7159 to various router environment issues) and FORWARDED is not needed
7160 anymore for anything. The protocol specification is yet to be
7163 Now, removed silc_server_packet_forward from server and the flag
7164 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7166 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Renamed NAMES command to USERS command. The NAMES was named that
7169 due to historical reasons. Now it is renamed. Also, rewrote
7170 parts of the USERS command. The nickname list is not sent anymore
7171 by the server. Only Client ID and mode lists are sent in the USERS
7172 command. Changed this also to the protocol specification.
7174 The client now resolves the names and stuff after it receives
7175 the USERS list from the server when joining to the channel.
7177 * WHOIS and IDENTIFY commands has been changed to support multiple
7178 Client ID's per command. One can now search for multiple users
7179 in the network by sending only one WHOIS or IDENTIFY command.
7180 Changed the code and the protocol specifications.
7182 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7183 uses silc_server_command_whois_parse to parse the request. */
7185 * If normal server, do not parse the WHOIS and IDENTIFY requests
7186 before sending it to the router. Saves some time.
7188 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Fixed JOIN command on client library. Wrong number of arguments
7191 used to crash the client.
7193 * Added silc_server_channel_has_global function to check whether
7194 channel has global users or not.
7196 * Added silc_server_channel_has_local function to check whether channel
7197 has locally connected clients on the channel.
7199 * The silc_server_remove_from_one_channel now checks whether the
7200 channel has global users or not after given client was removed from
7201 the channel. It also checks whether the channel has local clients
7202 on the channel anymore. If it does not have then the channel entry
7203 is removed as it is not needed anymore.
7205 * The silc_server_notify now checks on JOIN notify whether the joining
7206 client is one of locally connected or global. If it is global then
7207 the channel has now global users on the channel and that is marked
7208 to the channel entry. Also, it now saves the global client to
7209 global list who is joining and JOINs it to the channel. This is
7210 for normal server, that is.
7212 Changed silc_server_send_notify_on_channel,
7213 silc_server_packet_relay_to_channel and
7214 silc_server_packet_send_to_channel check if we are normal server
7215 and client has router set (ie. global client) do not send the
7216 message to that client, as it is already routed to our router.
7218 * Implemented LEAVE notify type handling in silc_server_notify
7221 * Tested LEAVE command in router environment successfully. Tested
7222 with two routers, two servers and two clients.
7226 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7228 * Implemented SIGNOFF notify type handling in silc_server_notify
7231 * silc_server_remove_id now removes the client entry from all channels
7232 it has joined and thusly sends SIGNOFF notify type.
7234 * Rewrote the NAMES list generation in server by removing two excess
7235 loops. The lists are created now inside one loop.
7237 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * silc_server_remove_channel_user checks now also global list
7240 for channel and client.
7242 * silc_server_new_channel_user checks now both local and global
7243 list for channel and client. Fixed a bug in client id decoding.
7244 Used to decode wrong buffer.
7246 * silc_server_channel_message checks now both local and global
7247 list for channel entry.
7249 * Tested channel joining (hence JOIN) in router environment
7250 successfully. Tested with two routers, two servers and two
7253 * Tested channel message sending in router environment successfully.
7255 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7257 * Added silc_server_save_channel_key into server.[ch] to save the
7258 received channel key in Channel Key payload processing. It is
7259 also used in JOIN command reply handling.
7261 Equivalent function silc_client_save_channel_key added into
7262 client.[ch] into client library.
7264 * Changed JOIN command reply to send information whether the channel
7265 was created or not (is existing already) and the channel key
7266 payload. Changed protocol specs accordingly.
7268 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7269 the request was sent by ID and not by nickname. Crashed on
7272 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7275 now correctly save the received data.
7277 * silc_server_free_sock_user_data now notifies routers in the
7278 network about entities leaving the network.
7280 At the same time implemented functions silc_server_remove_id
7281 and silc_server_send_remove_id to receive and send REMOVE_ID
7282 packets. The packet is used to notify routers in the network
7283 about leaving entities. The ID removed will become invalid in
7286 * Added function silc_idlist_del_server into server. Removes and
7287 free's server entry from ID list.
7289 * silc_server_private_message function now checks, if we are router,
7290 that the destination ID really is valid ID, naturally.
7292 * In router when NEW_ID packet is received (for new client) the
7293 hash of the Client ID is saved in the ID Cache but the
7294 client->nickname is set to NULL, instead of putting the hash
7297 IDENTIFY command now also checks that client->nickname must be
7298 valid. If it is not if will request the data from the server who
7299 owns the client. Added new function
7300 silc_server_command_identify_check.
7302 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7303 to set the command to already allocated Command Payload.
7305 * Tested private message sending in router environment with two
7306 routers, two servers and two clients. Fixed minor bugs and now
7309 * Fixed segfault from client's NAMES command. Used to crash if
7312 * Forwarded packets must not be routed even if it is not destined
7313 to the receiver. Changed server code comply with this.
7315 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7317 * Added `require_reverse_mapping' boolean value to ServerParams
7318 structure. If TRUE (not default) the server will require that
7319 the connecting host has fully qualified domain name.
7321 If the reverse mapping is not required and hostname could not be
7322 found the IP address is used as hostname.
7324 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Implemented version string checking to both client and server.
7327 The check is incomplete currently due to the abnormal version
7328 strings used in development version of SILC.
7330 * Changed all command functions in server to use the new
7333 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7335 * Changed char *data to unsigned char *data in ID Cache system to
7336 support binary data as ID Cache data. Changed code to support
7337 binary data in lib/silccore/idcache.c.
7339 * Renamed silc_server_packet_relay_command_reply to
7340 silc_server_command_reply as it is normal packet receiving
7341 function. Rewrote the function to accept command replys for
7342 servers and not only for clients.
7344 * Mark remote router always as registered server if we are connecting
7345 to it. Otherwise, commands sent by the router to us are ignored.
7347 * All ID List find routines now returns the ID Cache Entry pointer
7348 as well if requested.
7350 * WHOIS command works now in router environment, tested with two
7351 routers, two servers and two clients.
7353 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7354 in router environment (as it is almost equivalent to WHOIS) but
7355 hasn't been tested thoroughly. Added new functions:
7357 silc_server_command_identify_parse
7358 silc_server_command_identify_send_reply
7359 silc_server_command_identify_from_client
7360 silc_server_command_identify_from_server
7362 * Disabled route cache adding because adding two different ID's with
7363 same IP replaces the old cache entry thus giving wrong route.
7364 The entry->router->connection is always the fastest route anyway
7365 so route cache may not be needed. Of course, new routes maybe
7366 established after receiving the ID when the entry->router->connection
7367 might not be anymore the most optimal.
7369 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7371 * Add route cache for received ID for fast routing.
7373 * Added silc_server_packet_route to route received packet on router
7374 that is not destined to us.
7376 * Renamed silc_server_get_route to silc_server_route_get.
7378 * Added id_string and id_string_len fields into SilcServer to
7379 include encoded ServerID for fast comparing without excess
7380 encoding of the ID's.
7382 * Cleaned up WHOIS command on server side. Added following static
7385 silc_server_command_whois_parse
7386 silc_server_command_whois_check
7387 silc_server_command_whois_send_reply
7388 silc_server_command_whois_from_client
7389 silc_server_command_whois_from_server
7391 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7392 arguments in command replies. All command functions should be
7393 updated to use this macro.
7395 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Minor typo fixes on command reply handling on server.
7399 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Added silc_server_command_add_to_channel internal routine to add
7402 the client to the channel after router has created the channel and
7403 sent command reply to the server.
7405 * Added generic silc_server_send_command to send any command from
7408 * Use static buffer with ID rendering instead of duplicating data.
7410 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7412 * Fixed a channel user mode bug when joining to a channel server gave
7413 everybody channel founder rights, oops.
7415 * We mark ourselves as the router of the incoming server connection
7416 if we are router ourselves. This way we can check in some packet
7417 sending functions whether it is locally connected server. For
7418 incoming router connections we put NULL.
7420 * For router sending packets locally means now always sending the
7421 packet cell wide; to local clients and local servers. For normal
7422 server sending packet locally means sending it to only local
7425 * Fixed the JOIN command to really work in router environment. If the
7426 channel is created it is always created by the router. Router is
7427 also responsible of making the initial joining to the channel,
7428 sending JOIN notify to the sending server and distributing
7429 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7430 does not exist server doesn't do anything else but forward the
7431 command to the router which performs everything.
7433 * Added silc_server_send_channel_key function to send the Channel Key
7436 * Added silc_server_create_channel_key to create new channel key. The
7437 channel key is now re-generated everytime someone joins or leaves
7438 a channel, as protocol dictates. Note: channel->key_len is the
7441 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7444 packet_receive.[ch] to separate packet sending and receiving
7445 routines. The server.[ch] now includes everything else including
7446 actual packet processing (writing and reading data) and other
7449 Renamed silc_server_private_message_send_internal to
7450 silc_server_send_private_message. The routine is still though
7451 used only to relay private messages as server does not send
7452 private messages itself.
7454 Renamed silc_server_new_channel to silc_server_create_new_channel
7455 and added new function sicl_server_new_channel that handles the
7456 incoming New Channel packet. Added also new sending function
7457 silc_server_send_new_channel to send New Channel Payload.
7459 * Added new function silc_server_notify to process incoming notify
7460 packet to the server/router. Server may then relay the notify
7461 to clients if needed.
7463 * Added new function silc_server_new_channel_user to process incoming
7464 New Channel User packet. Router will redistribute the packet and
7465 send JOIN notify to its local clients and locally connected servers
7466 if needed. Normal server will send JOIN notify to its local client
7467 on same channel when received this packet. Added also corresponding
7468 sending function silc_server_send_new_channel_user to sent the
7471 * Added boolean route argument to send_notif_to_channel and
7472 packet_send_to_channel functions to attempt to route the packet
7473 if it is TRUE and send only locally if it is FALSE.
7475 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7477 * silc_server_replace_id now broadcasts the received replace ID
7478 packet if it is not broadcast packet already. The router must
7479 broadcast to inform other routers about changed ID.
7481 * Added backpointer to server's router into SilcServer context in
7482 silcd/server_internal.h.
7484 * Fixed silc_server_packet_broadcast to send correct broadcast
7487 * The channel key is now distributed to the local client as soon
7488 as it is received from the router (in router environment) so that
7489 no other packet may be sent for the channel until client has
7492 * silc_server_remove_channel_user now broadcasts the received
7493 Remove Channel User packet if it is not broadcast packet already.
7494 The router must broadcast to inform other routers about removed
7497 * Added users field into SilcPacketContext that is a reference count
7498 of the context. One can increase the reference count by calling
7499 silc_packet_context_dup which is now changed to just increase the
7500 reference count instead of duplicating the data. The reference
7501 count is decresed by calling silc_packet_context_free that will
7502 free the data after the reference count hits zero.
7504 For now on the packet context and everything allocated into it
7505 (including the raw packet from network) must be freed by calling
7506 the new silc_packet_context_free function. Added also new function
7507 silc_packet_context_alloc that must be used now to allocate the
7508 context. This also means that if a routine is asynchronous from
7509 silc_[client/server]_packet_parse_type the packet context must
7510 be duplicated by calling silc_packet_context_dup. Otherwise it
7511 gets free'd after silc_[client/server]_packet_parse_type returns.
7512 Also, one must remember that if packet is duplicated then its
7513 reference count must be decresed by calling the free function as
7514 many times as it was duplicated.
7516 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7517 from both client and server.
7519 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Made joining to a channel working in router environment.
7523 * Cleaned up JOIN command on server side and create function
7524 silc_server_command_join_channel internal routine to make the
7527 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7529 * Changed silc_command_pending list to SilcDList. Also, added
7530 `ident' field to SilcServerCommandPending structure to identify
7531 the reply and to call correct callback.
7533 Added silc_server_command_pending_check function to replace the
7534 corresnponding macro. The silc_command_pending list is not
7537 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7538 to set identifier to previously allocated Command Payload. It
7539 is used to set identifier for command when resending Command
7542 * Added silc_command_payload_encode_payload to encode Command
7543 Payload buffer from SilcCommandPayload structure.
7545 * Added silc_argument_payload_encode_payload to encode Argument
7546 payload buffer from SilcArgumentPayload structure.
7548 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * Changed WHOIS command to support router connection on server side.
7551 The whois request is always sent to router unless the server is
7552 standalone server. After server has received the reply from the
7553 router will it send the reply to the client.
7555 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7556 broadcast received broadcast packet. The function is used only
7557 by router. The broadcast packet is always sent to the router's
7560 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7561 render given ID to printable string, for log files for example.
7563 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * Made basic router to router connections working. At least they
7566 can now connect to each other but nothing really works the way
7567 they are supposed - yet.
7569 * Added new initiator token to RouterConnection configuration
7570 file in silcd/serverconfig.[ch]. It is used to tell whether we
7571 are the initiator to the remote router or whether we'll expect
7572 the other end to connect.
7574 * Moved registering of listener task to silc_server_init, hence
7575 the server starts listenning as soon as it is run, even if it
7576 does not have connections to other routers. Let's see how well
7579 * Changed default connection retry timeouts for more suitable in
7582 * Removed cipher and such arguments from silc_idlist_add_client
7583 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7584 Added new function silc_idlist_add_data to add the keys and stuff
7587 * Added SilcIDListData structure and added it to SilcClientEntry
7588 and SilcServerEntry as their first field in the structure. This
7589 way we can explicitly cast the ID entries to the SilcIDListData
7590 structure and get common data for the entries. In past, we had
7591 to first check what type of connection it is and then cast it to
7592 correct ID entry type. Now, we can directly cast the opaque
7593 pointer to the SilcIDListData (no matter what ID entry it actually
7594 is) and get the data needed.
7596 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7599 in some circumstances even if threre were timeout tasks, though not
7600 IO tasks, but tasks anyway. Now fixed.
7602 * Defined SilcServerConnection structure to hold connection specific
7603 stuff about directly connected servers and routers. The definition
7604 is currently in silcd/server_internal.h. I thought about having
7605 a bit more important role fro this struct but for now it is used
7606 only when connecting to other server (or router actually).
7608 * Added connecting retry support in server when connecting to
7609 router(s). The retry feature implement exponential backoff
7610 algorithm. Also, added SilcServerParams structure to hold default
7611 parameters for server. For now, it include these retry settings
7612 and are hard coded. After server is moded to be as Silc Server
7613 Library this structure will be more important.
7615 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7617 * Changed client librarys channel->clients table to SilcList and
7618 changed code accordingly.
7620 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7622 * Changed client's channel table to SilcList and changed code
7623 accordingly. Also changed SilcChannelClientEntry to include back-
7624 pointer to the channel so that client entry can use that structure
7625 as list as well and we have fast cross-reference to the channel.
7626 This change dramatically decreased the complexity of channel
7627 handling with client entry and vice versa (removed one extra
7628 loop when searching for channel entry from many functions).
7630 * Changed server->sim from table to SilcDList and changed code
7633 * NAMES command can now be used from user interface. It will show
7634 the user list on the channel, neatly.
7636 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7637 Code now saves realname of the user if it becomes available.
7639 * Renamed configure.in to configure.in.pre and made ./prepare
7640 script to automatically add correct version string to
7641 configure.in which it creates from configure.in.pre.
7643 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * NAMES command reply now shows users mode with the nickname when
7648 * Moved silc_client_ch[u]mode[_char] functions from
7649 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7650 place sucks, they are utility functions and should be in some
7653 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7655 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7658 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * Added TRQ (efficient deque and list library) into lib/trq. This is
7663 a very good list library that is currently used in the SILC. Defined
7664 SilcList API over the library because I didn't like the API very
7665 much. See lib/trq/silclist.h for the API and examples of how to
7666 use the API. Fixed various places in the code to use the new
7667 SilcList API. The SilcList is meant for lists that has a structure
7668 already defined as a list. It is not suitable to add just some
7669 context to the list (in TRQ, the context is the list actually).
7671 So, I defined SilcDList that can be used for the purpose where
7672 predefined list structure does not exit. This can be used as
7673 such list. Now some context just can be added to the SilcDList.
7674 Currently this list is not used in the SILC just yet, though there
7675 are a lot places where this can replace dynamically allocated
7676 tables and I will fix these places, later, to use SilcDList.
7677 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7678 and use TRQ internally).
7680 Also fixed some annoying warning messages that the original TRQ
7681 code generated. Also minor changes to TRQ's Makefile.in.
7683 * Added support for querying by Client ID to both WHOIS and
7684 IDENTIFY commands into server, as required by the protocol.
7686 * Removed method function pointers from SilcBuffer structure. They
7687 weren't used to anything and just increased the context size for
7688 no good reason. This change also made silc_buffer_alloc and
7689 silc_buffer_free functions inline functions.
7691 * Disabled command flooding detection support until it's fixed so
7692 that it accepts commands in but does not execute them more than once
7695 * Added silc_net_localhost(), to return local hostname, into
7696 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7697 that must be initialized before calling silc_client_init.
7699 * Added new function: silc_server_send_notify_on_channels to send
7700 notify messages to all channels client has joined. It is assured
7701 that the message is sent only once per client.
7703 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7704 lib/silcutil/silcutil.[ch] as silc_format function. The new
7705 function is generic and is used by server as well, not only by
7706 the logging routines.
7708 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7709 the provided version string was not acceptable. Added new function:
7710 silc_ske_check_version into lib/silcske/silcske.h. The function
7711 must be implemented by the application (client or server) and it
7712 does not reside in the SKE library. The function checks the version
7713 string remote end sent.
7715 * Added back pointers (to opaque context and to SilcSocketConnection)
7716 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7718 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7719 duplicate packet context structure.
7721 * Changed `notify' client operation to send same arguments as client
7722 receives from server except for ID's. ID's are mapped to correct
7723 ID entry and that is returned. Also, if channel entry is not sent
7724 by server but the notify is for channel the channel entry is sent
7725 to application (otherwise application doesn't know that it is for
7726 channel (library gets it from packet's Destination ID)).
7728 * Added silc_client_remove_from_channels into client library to
7729 remove a client from all channels it has joined to. Used when
7730 received SIGNOFF notify from server. Added also new function
7731 silc_client_replace_from_channels to replace old ID entry with
7732 new ID entry on all channels. Used when received NICK_CHANGE
7735 * Fixed ID Cache list handling in silc_idlist_get_client in
7736 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7737 to get (or query) client by ID.
7739 * Updated TODO list.
7741 * Added connection authentication status message defined by the
7742 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7743 support for these into the code in client and server side.
7745 * Added generic function silc_client_send_command to send any command
7746 with variable argument list. Application should use this function
7747 to send commands if the command functions provided by the library
7748 does not suite for the application's user interface needs.
7750 * Added new `failure' client operation. Application is notified about
7751 received failure packet if client is executing a protocol. In this
7752 case the protocol's execution has failed.
7754 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7755 is required by the protocol.
7757 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7758 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7761 * Added status flag to SilcSKE object to indicate realtime status
7762 of the SKE protocol.
7764 * Application receives now exactly same command reply arguments as
7765 the library receives from server. However, if ID is received the
7766 corresponding ID entry is returned to the application (eg. Client
7767 ID is mapped to correct SilcClientEntry entry and that is returned).
7768 Changed command_reply client operation due to this change.
7770 * Changed all ID's in commands and in command replys as ID Payloads.
7771 Change affected both client and server side codes.
7773 All ID's sent in SILC network (with execption of ID's in SILC
7774 Packet header) are sent in ID Payload to support variable length
7777 * Server now notifies nick changes and notifies all clients on
7778 the channels about the new nickname (about the new Client ID,
7781 * Implemented CMODE command to change channel modes. Supports all
7782 channel modes defined by the protocol specs except ban and invite
7783 lists. (Also, private channel key mode is supported but support for
7784 setting private channel key in client is missing, thus, this mode
7785 has no effect on client side (except that server requires that the
7786 client uses private channel key and normal channel traffic does not
7789 Also, invite mode works per se, but INVITE command does not work
7790 yet correctly, so you can set channel as invite only channel but
7791 inviting clients to the channel does not work (it is yet to be
7792 thought what's the best way to do it).
7794 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7795 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7796 Implemented CUMODE command to change user's mode on the channel.
7797 Supports all modes defined by the protocol specs.
7799 * Added NAMES command reply to return users modes on the channel.
7801 * Removed unnecessary and slow ciphers from lib/silccrypt.
7803 * Set SO_KEEPALIVE option to connection sockets by default.
7805 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7807 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7808 redefined the Notify Payload into protocol specs.
7810 * Added silc_id_payload_parse_id to get ID directly from raw
7813 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7815 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7816 accept searching by Client ID as well.
7818 * Added support for LEAVE and SIGNOFF notify types in client library.
7820 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7821 to parse ID Payload from raw data.
7823 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Added flags parameter into silc_ske_assemble_security_properties
7826 function in lib/silcske/silcske.[ch].
7828 * Changed notify client operation to fit better for notify messages
7829 sent by server. The notify payload received from server is now
7830 passed to the application (after parsing it to SilcNotifyPayload).
7831 It is application's responsibility to retrieve the arguments
7832 from the payload and show the message the way it wants. The message
7833 sent by server is implementation specific.
7835 * Changed public keys to comply with the protocol specification.
7836 Old public keys are not supported anymore and are not compatible.
7838 * Removed nickname from Channel Payload as the latest draft removed
7839 it. The client must resolve the nickname from the NAMES command
7840 reply received when it joined the channel.
7842 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7844 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7846 * Fixed some errors in protocol specification drafts.
7848 * Created lib/silccore/silcnotify.c to implement Notify Payload
7849 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7850 generic payloads described by protocol specifications. The file
7851 includes implementations for ID Payload and Argument Payload.
7853 * Changed Command Payload implementation to use the new Argument
7854 Payload. Changed command_xxxx_payload to command_payload_xxxx
7855 to comply with SILC coding conventions.
7857 * Added suppport for Argument Payload handling in Notify Payload
7858 implementation as protocol requires it. Added the new support
7859 into server and client lib as well.
7861 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Added support for multiple nicknames on same channel. [n] is
7864 added locally to the nickname if there are more than one same
7865 nicknames on the channel.
7867 * Server now sends all nicknames that matched WHOIS request.
7868 Client also shows the list received from server.
7870 * Added TOPIC command to client side. User can now set and show
7871 current topic on channel.
7873 * Added MOTD command to client and server. Also, server sends the
7874 motd when client connects to the server.
7876 * Changed version strings to comply ISO 8601.
7878 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Fixed protocol error handling in client library. It should now
7881 cope even if the SKE fails for some reason.
7883 * Made new protocol specification drafts for submitting to IETF.
7885 * Implemented TOPIC command to server in silcd/command.c.
7887 * Added two new notify types into lib/silccore/silcnotify.h:
7888 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7889 notify nickname change and topic setting/change on a channel.
7891 * API change of command_reply operation in client library. The
7892 application gets now the status type received from server as well.
7894 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7896 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7898 * Cras fixed and optimized the packet handling even further and
7899 it should work now. Minor change to the prototype of function
7900 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7902 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7904 * Added new function into lib/silcutil/silcschedule.[ch]:
7905 silc_schedule_with_fd to select() a specified fd. The function
7906 returns after timeout expires or data arrives or goes. The
7907 function is used by packet routines to wait that all data is
7908 received from network.
7910 * Fixed data reading from network in lib/silccore/silcpacket.c.
7911 The code now assures that all data is read from the fd and then
7912 continues packet processing. This was a bug fix since the code
7913 used to drop some data in some circumstances.
7915 * Added new function into lib/silcclient/client.[ch]:
7916 silc_client_start_key_exchange to start key exchange after
7917 connection has been established to server. The code internally
7918 now uses this funtion but its main purpose was to provide it
7919 for applications that perform their own connecting. After
7920 application has created a connection it merely calls this
7921 function to start the key exchange between client and server.
7922 The library takes care of everything else after that.
7924 Updated also lib/silcclient/README to explain the usage of
7927 * Do not send to application information that connection has
7928 been established. Application gets notified it by connect
7931 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7933 * Applied cras's patch to add silc_schedule_one function. The
7934 function runs scheduler once and returns.
7936 * Fixed the scheduler after cras messed it up. The timeout
7937 handling works now as it's supposed to work.
7939 * Added into lib/silccore/ silcnotify.h to include notify
7940 message types support. Changed silc_server_send_notify*
7941 functions, in server.[ch], to support those new notify types.
7942 Added the support for the notify types into client library,
7943 as well. Added new notify client operation into ops.h in
7946 * Changed silc_server_packet_send_to_channel to send normal
7947 packets instead of just channel message packets. The function
7948 is now used to send the notify packets to channels. It is not
7949 used to send channel message packets anymore, as server never
7952 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7953 va_arg()s as it seems to require it nowadays. I guess, if SILC
7954 is compiled with older va_arg() the new code should work anyway.
7956 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7958 * Splitted core library. Core library (lib/silccore) includes
7959 now only SILC protocol specific core (and common) components.
7960 Created new utility library (lib/silcutil) that includes more
7961 generic purpose stuff. The stuff for util library was taken
7962 from the old core library. This was minor and easy split.
7964 * Created SILC Client Library (lib/silcclient) that includes
7965 implementation of the SILC client without user interface. This
7966 was major move from silc/ directory. The code has been changed
7967 so that it is transparent towards the user interface. The
7968 silc/ directory includes now the same user interface as before
7969 and it uses the new client library. Read lib/silcclient/README.
7970 Basicly, the client library performs everything else related
7971 to SILC except user interface handling. Also, configuration
7972 files are considered to be part of user interface and library
7973 does not handle them.
7975 This change also changed a lot of structures, function naming etc.
7976 Most important change was that SilcClientWindow object was
7977 renamed to SilcClientConnection in the client library. Created
7978 also new file lib/silcclient/ops.h. Also added new files
7979 silc/local_command.[ch] and silc/client_ops.[ch].
7981 All these changes were made to make it easier for user interface
7982 designers to create what ever user interface for the SILC client
7985 It is also expected that the server will be moved to lib
7986 directory as well and SILC Server Library will be created;
7987 sometimes in the future.
7989 * Removed Local commands from lib/silccore/silccommand.h as
7990 they are application specific and new client library does not
7991 handle any of those anymore.
7993 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7994 old client implementation in silc/.
7996 * Added support for callback functions in SILC_LOG_* macros.
7997 Application can now set its own callbacks that will be called
7998 instead of using the default functions that will always print
7999 the debug messages to stderr (or stdout). Also, debugging can
8000 now be disabled by setting silc_debug to FALSE and re-enabled by
8001 setting it to TRUE. Note, that logging will still work even
8002 if debugging is disabled.
8004 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8005 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8006 silc_log_reset_debug_callbacks.
8008 * To enable debugging in silc client one must give now -d
8009 option on command line.
8011 * Changed silc_schedule_init to automatically allocate task queues
8012 if they are not allocated before calling it.
8014 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8016 * Added GMP 3.1 into math library.
8018 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8020 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8021 a channel in SILC network. The packet is used by servers and
8022 routers to notify other routers that user has left a channel.
8023 This little feature was missing until now. Added the feature
8024 to protocol specification as well.
8026 Added functions: silc_server_send_remove_channel_user and
8027 silc_server_remove_channel_user into server.[ch].
8029 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8030 lib/silccore/silcpacket.h. However, they are not implemented
8033 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8035 * Fixed joining to a channel and sending channel messages
8036 between server and router. The channel message sending should
8037 now work inside a cell.
8039 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8041 * Fixed the private message sending between server and router.
8042 The private message sending should now work inside a cell.
8044 * Added silc_server_replace_id into server.[ch] to replace
8045 existing ID in the SILC network.
8047 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8048 and silc_idlist_replace_server_id into idlist.[ch] in server.
8050 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8052 * Fixed the server to server connections. Server can again now
8053 connect to router. Router to router connections probably does
8056 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8058 * Added dynamic protocol registering support. Now protocols can
8059 registered and unregistered on the fly. Patch by cras.
8061 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8063 * Added lib/contrib directory to hold routines that some platforms
8064 don't have but are needed by SILC.
8066 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8067 into lin/contrib to provide getopt() and getopt_long() for
8068 those who don't have it.
8070 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8072 * Added AWAY command to client. When away message is set and
8073 client receives a private message packet the client automatically
8074 replies to the sender with the away message.
8076 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8077 bug seemed to be the cause of recent problems when compiling
8080 * Added version detection support to SKE protocol specification
8081 and added the new changes to the SKE implementation as well.
8082 There were other minor changes in the SKE protocol as well.
8084 Many changes in lib/silcske/silcske.[ch] and in
8085 lib/silcske/payload.[ch].
8087 * Added ^U functionality, clear input line. Patch from cras.
8089 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8091 * Mainly small bugfixes on core library. Fixed some debugging
8092 logging and buffer overflow in silclog.c.
8094 * Updated config.sub and config.guess on the distribution tree.
8096 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8098 * Added command lagging support in server. Client may execute
8099 commands now only once in two seconds.
8101 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8103 * Optimized packet reception. MAC computation and checking is now
8104 also more optimized. A lot previously duplicated code is now
8105 used as generic by both client and server.
8107 * Fixed key pair generation in clientutil.c
8109 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8111 * Added into lib/silccore/silcbufutil.[ch] new function;
8112 silc_buffer_realloc.
8114 * Moved generic packet sending/encryption functions to
8115 lib/silccore/silcpacket.[ch] from client and server. Some
8116 rewriting of the functions.
8118 * Moved all generic packet reception/decryption functions to
8119 lib/silccore/silcpacket.[ch] from client and server. The
8120 packet processing is now much cleaner in both client and server.
8121 These were major changes in both client and server.
8123 * Created many common functions in server to do packet sending.
8124 Previously code were duplicated a lot, this has been removed
8127 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8129 * Rewrote major parts of the ID cache system. Don't know
8130 whether it is better now or not but at least the API is more
8133 * Major rewrite on ID cache stuff on client because of the ID
8134 cache API changes. Added idlist.c to client.
8136 * Also major rewrite on ID cache stuff on server as well.
8137 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8138 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8139 in hand, instead they are all put into the ID cache system now.
8140 All server_idlist_* routines uses ID cache now instead of
8141 traversing its own lists (those lists does not exist anymore).
8142 SilcIDList though still exists. Also, SilcXXXEntry's are
8145 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8147 * Finally made the SKE implementation compliant to the protocol
8148 specification. All mp integers are now binary encoded as
8149 opposed being HEX encoded.
8151 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8154 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8155 functions: silc_[encode/decode]_pem. Also added function
8156 silc_encode_pem_file to PEM encode with newlines ('\n') for
8159 * SILC public keys are now encoded either PEM or binary. Same
8160 option is for private keys as well. By default private keys
8161 are binary encoded and public keys PEM encoded. Silly HEX
8162 encoding were removed.
8164 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8165 function to create fingerprints.
8167 * Fixed a bug in SHA1; does not change the original data anymore.
8169 * Partly implemented INFO command on client and server side.
8170 Fixed CLEAR command. Changes to SERVER command; show current
8171 server(s) when giving command without arguments. Added
8172 VERSION command to client.
8174 * Added check to server that unregistered connections cannot
8175 execute commands (unless it is specificly allowed).
8177 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8179 * Fixed screen refresh.
8181 * Fixed channel joining bug from client. On some circumstances
8182 client tried to join to a channel it had already joined.
8184 * Added public key verification process into client's protocol.c.
8185 The client now verifies the public key from user and saves
8186 it into ~./silc/serverkeys/ directory.
8188 Added into: clientutil.[ch]: silc_client_verify_server_key.
8190 * Changed SKE protocol's silc_ske_initiator_finish function
8191 to accept callback function that verifies the received public
8192 key. Removed old silc_ske_verify_public_key function.
8194 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8197 silc_pkcs_private_key[_data]_set.
8199 * Made the password and public authentication more cleaner in
8200 server's protocol.c.
8202 * Removed historic and obsolete protocol `channel_auth' from
8203 both client and server.
8205 * Removed wrong way of sending command status messages from
8206 server to client in server's command.c. The old way violated
8207 protocol specification.
8209 Changes to silccore/silccommand.[ch]: removed
8210 silc_command_encode_status_payload -> not needed anymore,
8211 changed silc_command_encode_payload_va to accept extra
8212 argument on variable argument list. The argument type must
8213 now be provided to the function. Also, added new function:
8214 silc_command_encode_reply_payload_va which is same as
8215 normal command_encode_payload_va except command status type
8216 is provided as extra argument.
8218 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Added ~./silc directory handling. The directory includes the
8221 public and private keys for the client.
8223 Added silc_client_check_silc_dir, silc_client_create_identifier
8224 and silc_client_load_keys.
8226 * Implemented SILC protocol compliant public key. Added public
8227 and private key saving to and loading from files.
8229 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8230 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8231 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8232 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8233 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8235 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8236 silc_pkcs_load_[public/private]_key.
8238 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8240 * Added silc_server_get_route (route.[ch]) to get connection
8241 data for the fastest route for given ID.
8243 * Implemented INVITE command on client and server. The command
8244 were re-defined in the SILC Protocol Specification and the
8245 implementation now complies with the specification.
8247 * Implemented PING command on client and server.
8249 * Implemented NAMES command on client and server. The server side
8250 supports currently only normal server not router server yet.
8251 Some changes to NAMES definition in SILC protocol specification.
8253 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8255 * Implemented LEAVE command on client and server.
8257 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8258 again. This change was made to the protocol as well. Server
8259 should not violate the protocol specification anymore.
8261 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8264 was tested. SOCKS4 was not but should work anyway.
