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

98 SilcCommandStatus to SilcStatus.
100 * Defined the use of extra WHOIS attributes in WHOIS command.
101 The <Requested Attributes> (defined in a separate document)
102 can be used to request additional information about user
103 not returned by standard WHOIS command. Defined that server
104 can send WHOIS command directly to client. Client provides
105 the requested attributes to the server. Updated the protocol
106 specs. Protocol TODO #4. Implementation is not done yet
109 * Renamed function silc_client_command_status_message to
110 silc_client_status_message. Affected files are

134 * Added resolve_cmd_ident field to the SilcClientEntry structure
135 too so that if the entry is for example being resolved so
136 another command may attach to the same pending command reply
137 without requiring to resolve the same entry again. Added
138 support for adding multiple pending commands for one
139 command idenfier. Affected files lib/silcclient/command.[ch],
140 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
142 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

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

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

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

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

305 * Changed the silc_client_close_connection interface to not
306 need the SilcSocketConnection which should not be visible
307 to application. Affected files are lib/silcclient/client.c
308 and lib/silcclient/silcclient.h.
310 * Rewrote the text for Private Message Key Payload in the
311 protocol specification. Protocol TODO #11.

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

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

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

424 totally saved 16 bytes of memory per context after optimization.
425 Affected files are lib/silccore/silcpacket.[ch].
427 * Made strict checks for valid SILC IDs. Affected file is
428 lib/silccore/silcid.c.
430 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
432 * Changed the object argument for silc_cipher_register,
433 silc_hash_register, silc_hmac_register and silc_pkcs_register
434 to const. Affected files are lib/silccrypt/silccipher.[ch],
435 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
437 * Changed the silc_get_username and silc_get_real_name to
438 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
440 * Fixed the Irssi SILC Client to use the silc_get_username and
441 silc_get_real_name insted of glib routines since the glib
442 routines only corrupt stack. Fixes the Irssi SILC to work in
443 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
445 * Fixed the Irssi to not use g_get_home_dir since it crashes
446 or returns garbage on cygwin and corrupts stack. Added function
447 get_home_dir to Irssi routines. Affected files are
448 irssi/src/core/misc.[ch] and irssi/src/core/core.c.

454 SilcPacketContext structure.
456 Affected files lib/silcsftp/sftp_fs_memory.c,
457 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
459 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
461 * And yet again reverted back the config thing since Johnny
462 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
465 * Fixed memory leaks from config object. Affected files are
466 silcd/serverconfig.[ch].
468 * Added support for adding new connections to the server in rehash.
469 After rehash they take effect.
471 Added support for changing the maximum allowed connections in
472 rehash. The number can grow but going smaller is not supported.
474 Added function silc_server_num_sockets_by_remote to the
475 silcd/server_util.[ch].
477 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
479 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

482 public/private key and removed further checks in the code.
483 Affected files are silcd/serverconfig.[ch], server.c.
485 * Moved functions silc_server_drop() and silc_server_daemonise()
486 from server.c to silcd.c since they are stricly related to
487 the application activity.
489 * Reverted a small part of the automatic ref/unref since

498 address. Affected file lib/silcutil/silcnet.c.
500 * Fixed the notify relaying to client. The HMAC to be used
501 with relayed packets ws wrong and caused decryption failure
502 at the client end. Affected file is silcd/packet_receive.c.
504 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Created new branch silc_protocol_1_0_branch.
508 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
510 * Changed the silc_server_config_* routines to be SilcServer
511 independent. They are now officially application specific code
512 and not part of generic server implementation. Affected files
513 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
515 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
517 * Added automatic referencing of config context in the
518 silc_server_config_alloc, and automatic unreferencing in the
519 silc_server_config_destroy. Affected files are
520 silcd/serverconfig.[ch], silcd/silcd.c.
522 * Fixed the silc_log_quick handling in the logging routines.
523 It didn't log quickly when it was TRUE. Affected file is
524 lib/silcutil/silclog.c. Also the flush delay was set even
525 if it was 0 in config file. Affected file is
526 silcd/serverconfig.c.
528 * Added support for changing key pair of the server in rehash.
529 Affected file silcd/server.c.
531 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
533 * Fixed the TOPIC_SET notify to not cras. It changed the topic
534 too early, before getting the channel entry. Affected file
535 is silcd/packet_receive.c.
537 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
539 * Added functions silc_server_config_[ref/unref], these are used
540 to prevent that the config object is destroyed.
542 No longer directly affect global variables silc_log_quick and
543 silc_log_delay, they are first cached inside the config object
544 and then applied with silc_server_config_setlogfiles().
546 silc_server_config_set_defaults() is now internal to
547 serverconfig.c, there are no reasons to show this internal stuff
550 Affected files are silcd/serverconfig.[ch].
552 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
553 fprintf's to stderr, since some code may be executed again after
554 the server went into the background. Affected files are
557 * Added rehash support. Added function silc_server_rehash() that
558 will perform all the basic tasks of the rehashing procedure.
560 * Added command line option `-x, --hexdump'. This will enable the
561 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
562 The option `--hexdump' implies `--debug'.
564 * Fixed a bad bug in the logging APIs (silcutil library) where
565 the application would crash after calling silc_log_reset_all().
567 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
569 * Fixed the KICKED notify handling in client library to
570 correctly remove the channel and all entries from the
571 channel when I was kicked. This bug crashed the client.
573 Fixed yet another but in KICKED notify handling to remove
574 the kicked client correctly from the channel.
576 Affected file is lib/silcclient/client_notify.c.
578 * Fixed a minor bug in looking up correct client entry
579 in KICKED notify in server. Affected file is
580 silcd/packet_receive.c.
582 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
583 sources correctly to distribution. Fixes --with-gmp option.
585 * Removed the manual rehashing from ID Cache, and changed it
586 to use the SILC Hash Table's auto rehash feature. Affected
587 file is lib/silccore/silcidcache.c.
589 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
591 * Fixed a bug in the silc_client_nickname_format function that
592 handles the multiple same nickname formatting. Two clients
593 with same nickname caused problems after the first one left
594 and rejoined. It didn't format the nickname correctly.
595 Affected file is lib/silcclient/idlist.c.
597 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
599 * Don't change the topic if olod topic is same as new one.
600 Affected file is silcd/packet_receive.c.
602 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Added cross-reference support to the SILC Documentation
605 generator. All types across all HTML files are now cross-
606 referenced. Affected files util/robodoc/generator.c and
607 scripts/silcdoc/silcdoc.
609 * Added file lib/silcutil/silctypes.h to include all the
610 arithmetic type definitions and some macros. Removed
611 includes/bitmove.h and moved macros to silctypes.h.
613 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
615 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
617 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
619 * Added `type' argument to silc_id_payload_parse_id function which
620 now returns the type of the ID to the sent pointer. Affected
621 file is lib/silccore/silcid.[ch].
623 * Added check for CMODE_CHANGE notify type that mode change is
624 allowed by the sender. Affected file silcd/packet_receive.c.
626 * Added check for CUMODE_CHANGE notify type that mode change is
627 allowed by the sender. Affected file silcd/packet_receive.c.
628 Added the ID type as CUMODE_CHANGE notify type as argument
629 to the `notify' client operation. Affected files are
630 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
632 * Added function silc_client_add_server to the client library.
633 Added support for resolving also channel and server info when
634 received unknown entity in notify packet. Affected files are
635 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
637 * Added function silc_command_get_status to return the command
638 status from the command reply's argument payload. Affected files
639 are lib/silccore/silccommand.[ch].
641 * Added check for KICKED notify type that the kicking is
642 allowed by the client. Affected file silcd/packet_receive.c.
644 * Created function silc_get_input which can be used to get input
645 (echo on or off) from user on command line. Affected files are
646 lib/silcutil/silcutil.[ch].
648 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Optimized silc_server_packet_relay_to_channel function.
651 Added new function silc_channel_message_payload_encrypt which
652 can be called directly if channel message payload needs to
653 be encrypted and is already encoded (no need to call _encode
654 function). Packet relaying is now done by router without any
655 extra memory allocations. Affected files are
656 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
659 * Fixed the INVITE notify handling. It took wrong arguments
660 as invite list and invite delete. Affected file is
661 silcd/packet_receive.c.
663 * Added check for TOPIC_SET notify type that the topic change is
664 allowed by the client. Affected file silcd/packet_receive.c.
666 * Added check for INVITE notify type that inviting is allowed by
667 the client. Affected file silcd/packet_receive.c.
669 * Changed the silc_server_client_on_channel to return the
670 SilcChannelClientEntry as well. Moved the function
671 silc_server_check_cmode_rights to server_util.[ch].
672 Affected files are silcd/server_util.[ch], silcd/command.c.
674 * Added function silc_server_check_umode_rights to check whether
675 changing client's user mode is allowed. Added check for
676 UMODE_CHANGE notify type that the umode change is allowed
677 by the client. Affected files are silcd/server_util.[ch],
678 silcd/packet_receive.c and silcd/command.c.
680 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
682 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
683 ID length. It ignored that ID can be IPv6 based as well.
684 Affected file lib/silccore/silcpacket.h.
686 * Fixed the silc_id_id2str and silc_id_str2id to take the
687 IPv6 address offset's into consideration. Affecte file is
688 lib/silccore/silcid.c.
690 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
692 * Fixed the internal Unix scheduler functions to check for
693 NULL context they may receive. The affected file is
694 lib/silcutil/unix/silcunixschedule.c.
696 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
698 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
699 can specify different directory with --home command line
700 parameter. Affected files irssi/src/silc/core/client_ops.c,
703 * SILC-specific commands aren't now executed if the active server
704 isn't of SILC-type, so there won't be problems with having
705 IRC and SILC protocol support in same client. Affected files
706 irssi/src/silc/core/silc-channels.c, silc-servers.c,
709 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
711 * Improved the signal support in SILC Schedule. Added new
712 function silc_schedule_signal_call which is used by application
713 to mark a signal to be called. It is now safe to perform
714 any kind of tasks in signal callbacks since it is guaranteed
715 that the application specified signal callback is called
716 after the signal is over. Affected files are
717 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
719 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
721 * Added `name' field to SilcChannelPrivateKey to represent
722 application given name for the key. Moved also the context from
723 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
724 Added the `name' argument also to the function
725 silc_client_add_channel_private_key.
727 Added function silc_client_current_channel_private_key to set the
728 current channel private key in use.
730 Added "change" command to KEY command which can be used to change
731 the current channel private key. Bound the command also to
734 Also affected files lib/silcclient/client_channel.c,
735 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
737 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Added silc_rng_get_byte_fast function in to the
740 lib/silccrypt/silcrng.[ch].
742 * Changed the interface of silc_packet_assemble and the
743 silc_packet_send_prepare. If silc_packet_assmble is now
744 called the application does not call silc_packet_send_prepare
745 because the library will call it automatically. These
746 interfaces now also return a reference to the outgoing buffer
747 which includes the assembled packet, which the application can
748 use to encrypt the packet.
750 Affected files are lib/silccore/silcpacket.[ch],
751 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
752 silcd/packet_send.c, server_backup.c and packet_receive.c.
754 * Fixed a packet sending bug on very high load, where outgoing
755 packet queue wasn't handled correctly and packets got corrupted.
756 Affected files are lib/silcutil/*/silc*sockconn.c,
757 lib/silcclient/client.c and silcd/server.c.
759 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
761 * Added macro SILC_PACKET_DATALEN which can be used during
762 packet assembling to check whether the data to be added to
763 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
764 len is truncated until it fits it.
766 Added checks for maximum length of channel message payload and
767 private message payload also.
769 Added checks for maximum packet length in server and in
772 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
773 lib/silcclient/client.c, lib/silccore/silcchannel.c and
774 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
775 lib/silcclient/client_prvmsg.c.
777 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
779 * Added silc_server_packet_queue_purge call to the
780 silc_server_disconnect_remote to assure that all data in the
781 queue before disconnecting is sent to the network. Affected
784 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
786 * Added the deleting of server's own ID cache entry to the
787 silc_server_free function. Free also everything else that
788 has been allocated in silc_server_init. The affected file
791 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
793 * Added functions silc_parse_version_string, silc_version_to_num,
794 and silc_ske_parse_version to parse SILC protocol style version
795 strings. Affected files lib/silcutil/silcutil.[ch] and
796 lib/silcske/silcske.[ch].
798 * Added new configuration params: version_protocol, version_software
799 and version_software_vendor to specify what version the remote
800 host must at least be to be able to connect to server. The vendor
801 string can be regex matched too. Added new function
802 silc_server_connection_allowed to check maximum number of allowed
803 connections, and allowed versions for incoming connections.
804 Affected files are silcd/server.c, server_util.[ch] and
807 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
809 * Added preliminary support for signals in scheduler. The
810 signals we care about are now blocked always when the scheduler
811 is locked. This way we can synchronise the use of signal with
812 scheduler. It is guaranteed that when signal occurs the scheduler
813 is not locked, and thus new tasks can be safely added to the
816 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
817 to silc_schedule_internal_init and silc_schedule_internal_uninit.
818 Added new platform specific routines
819 silc_schedule_internal_signals_[un]block and
820 silc_schedule_internal_signal_[un]register.
822 Added new functions to SILC Schedule API:
823 silc_schedule_signal_[un]register. Each signal that application
824 is going to use should be registered to the scheduler.
826 Affected files are lib/silcutil/silcschedule.[ch],
827 lib/silcutil/*/silc*schedule.c.
829 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
831 * Check for unauthenticated client and server in the
832 silc_server_new_client and silc_server_new_server functions.
833 Affected file silcd/packet_receive.c.
835 * Added function silc_string_is_ascii to check whether given
836 string is 7-bit ASCII string. Affected files are
837 lib/silcutil/silcutil.[ch].
839 * Added function silc_id_is_valid_server_id into the
840 silcd/serverid.c and added checking for valid Server ID's in
841 silc_server_new_server. The Server ID must always be based
842 on the server's public IP address.
844 * Added logging of DISCONNECT packet message in the server.
845 Affected file silcd/server.c.
847 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
849 * Changed all library interfaces that use Global RNG to also
850 accept SilcRng as argument. Affected files are
851 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
852 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
853 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
854 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
857 * Added function silc_pkcs_generate_key to the
858 lib/silccrypt/silcpkcs.[ch] for applications so that they
859 don't need to do pkcs->pkcs->init calls anymore.
861 * Remove SilcSocketConnection from the SFTP API since it really
862 wasn't needed there. The application has the information
863 saved in its contexts anyway and the SFTP layer doesn't need
864 know about it. Affected files lib/silcsft/silcsftp.h and
865 lib/silcsftp/sftp_[server/client].c.
867 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
868 The SilcSimContext is not SilcSim.
870 * Fixed possible buffer overflows in silc_id_render in the
871 lib/silcutil/silcutil.c.
873 * On EPOC the global crypto module lists are not used at all
874 in the crypto library. Added support for using the constant
875 algorithm list on EPOC. Affected files are
876 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
879 * Fixed the handling of third parameter of KICKED notify, since
880 it was mistakenly updated to SILC Protocol 1.0 even though it
881 is to be included in 1.1. Since it is not in 1.0 it is not
882 mandatory, and this fix now handles it only if it is provided,
883 and it is not error if it is not provided. Affected file
884 lib/silcclient/client_notify.c.
886 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
888 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
889 client. Affected file irssi/src/silc/core/client_ops.c.
891 * Merged with Irssi 0.8.4 from irssi.org CVS.
893 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Check for valid socket connection in client entries before
896 sending any messages. Fixes a crash, but doesn't fix some
897 other underlaying bug that is lurking there. Affected
898 file silcd/packet_send.c.
900 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
902 * $usermode, $cumode and $cumode_space expandos shouldn't do
903 anything with non-SILC server records. Affected file
904 irssi/src/silc/core/silc-expandos.c
906 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Fixed the silc_net_check_[host/local]_by_sock to support
909 IPv6 bound sockets as well. Now they can return IPv6 addresses
910 as well. Affected file lib/silcutil/silcnet.c.
912 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
913 Affected lib/silcutil/unix/silcunixnet.c.
915 * Fixed ID rendering (at least on some platforms, not NetBSD)
916 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
918 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Added silc_hash_public_key and silc_hash_public_key_compare
921 functions to be used with SilcHashTable. They can be used to
922 hash public keys and compare public keys in hash table. Affected
923 file lib/silcutil/silcutil.[ch].
925 * Added support for specifying multiple public keys for Client
926 connection section in server configuration file. This makes it
927 possible to accept multiple public keys from same host, or to
928 make a section that accepts any incoming host, and have the
929 accepted public keys listed in the section.
931 Added functions silc_sever_[find/get]_public_key, added the
932 support for this actually to all connection sections but only
933 the Client section is currently allowed to specify multiple
936 Affected files are silcd/server.c, server_internal.h,
937 command.c, protocol.c, server_util.[ch], packet_receive.c.
939 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * Merged Irssi 0.8.2 from irssi.org CVS.
943 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
945 * If silc_debug is TRUE, also output standard logging messages
946 to stderr with the debug output.
948 Made silc_log_reset_all() flushing all channels before returning.
949 Also fixed some documentation typos.
951 Affected files are lib/silcutil/silclog.[ch].
953 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
955 * Fixed the server to check correctly the amount of connections
956 from single host, by checking also the type of the connection.
957 Fixed also the comparison of number of connections and number
958 of allowed connections. Affected files are silcd/server.c,
961 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
963 * Fixed the USERS command reply to save the user's mode on the
964 channel as well. Fixed JOIN command reply to check whether a
965 client is on channel already and not join it twice. Affected
966 file lib/silcclient/command_reply.c.
968 * Added new file silc-expandos.c into irssi/silc/core/ to return
969 various stuff for various signal for the statusbar etc. updating.
970 Now Irssi SILC client prints channel user modes etc. on the
973 * The user mode (like server/router operator changes) is now shown
974 on the Irssi SILC client's statusbar. The affected files are
975 irssi/src/silc/core/client_ops.c, silc-expandos.c.
977 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
980 to SILC_SCHEDULE_[UN]LOCK macros.
982 * Added more error printing to logs in server code. Affected
983 files silcd/server.c and silcd/protocol.c.
985 * Fixed -S option parsing in Irssi SILC Client. Affected file
986 irssi/src/silc/core/silc-core.c.
988 * Added silc_buffer_alloc_size function. Affected file is
989 lib/silcutil/silcbuffer.h.
991 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
994 constants. Affected files in
995 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
998 * Changed the internal SFTP Memory FS table to const. Affected
999 file lib/silcsftp/sftp_fs_memory.c.
1001 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1003 * Fixed the buffer formatting and unformatting routines to
1004 check the size of 64 bits types with sizeof(). Affected
1005 file is lib/silcutil/silcbuffmt.c.
1007 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1009 * Removed 0.6.x backwards support.
1011 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1013 * Changed all integer type names:
1014 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1015 to avoid collisions with other libraries using same type names
1018 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1020 * Added `prefer_ipv6' argument to the functions
1021 silc_net_gethostbyname[_async]. If it is TRUE it will return
1022 IPv6 address over IPv4. If FALSE IPv4 address is returned
1023 even if IPv6 address was found. Affected files
1024 lib/silcutil/silcnet.[ch].
1026 * Added support silc_net_create_connection[_async] to fallback
1027 to IPv4 address if IPv6 address could not be used (like if

1040 application does not need to define them. Affected file
1041 includes/silcincludes.h.
1043 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1044 old name went against naming convention. Applications now
1045 include "silcclient.h" instead of "clientlibincludes.h".
1046 Removed includes/clientlibincludes.h, it is redundant now.
1048 * Renamed includes/version.h to silcversion.h.
1050 * Added really preliminary support for OS/2 into the util

1108 the SKE interface a bit.
1110 * Fixed padding problem in PKCS#1. The padding was not actually
1111 random since the random number generator was used incorrectly.
1112 This security bug affects only when encrypting with PKCS#1, and
1113 it is not currently used at all in SILC. SILC only use signing
1114 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

1199 the connection configuration object from the SilcServerConnection
1200 object instead of finding it during the connecting phase.
1201 Added the configuration object to SilcServerConnection struct.
1202 Affected files silcd/server_internal.h, server.c.
1204 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1206 * Add the client on channel after it was resolved at the
1207 channel message receiving, and it was not already on the
1208 channel. Affected file lib/silcclient/client_channel.c.

1228 Added `prefer_passphrase_auth' setting in config file which
1229 can be used to set to prefer passwd auth if both passwd and
1230 public key is set. If not set, public key is preferred.
1231 This has effect only when being initiator (responder will try
1234 Added support for authentication with passphrase and public key
1235 at the same time. The passphrase is tried first always since
1236 it is faster to check.
1238 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1240 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1287 zero port also if the hostname is NULL because it could not
1290 Call file transfer monitor callback now also if error occurs
1291 during key agreement protocol.
1293 Changed the silc_client_file_send interface to return the
1294 SilcClientFileError instead of session id. The session ID
1295 is returned into pointer provided as argument.

1367 * Fixed a bug in hash table tarversing. While the hash table
1368 is traversed with SilcHashTableList the table must not be
1369 rehashed. It is now guaranteed that auto rehashable tables
1370 are not rehashed while tarversing the list. Also defined that
1371 silc_hash_table_rehash must not be called while tarversing
1372 the table. Added function silc_hash_table_list_reset that must
1373 be called after the tarversing is over. The affected files are
1374 lib/silcutil/silchashtable.[ch].
1376 * Changed all hash table traversing to call the new
1377 silc_hash_table_list_reset in server and in client library.
1379 * Added function silc_client_on_channel to return the
1380 SilcChannelUser entry if the specified client entry is joined
1381 on the specified channel. This is exported to application as
1382 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

1391 lists correctly. Affected file silcd/command.c.
1393 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * When sending JOIN command to router for processing the
1396 sender's old command identifier was not saved back to the
1397 sender's command context, fixed now. The affected file is
1400 * Create the key in JOIN command of the router did not return
1401 the channel key, added check for this. Affected file is
1404 * Fixed a channel ID update bug in JOIN command reply. Do
1405 not directly upgrade the ID but call the function

1527 method if the IP address based filename is not found.
1529 Fixed the GETKEY command to save the fetched server key
1530 in correct filename.
1532 Print the remote server's hostname now when new key is

1558 * Added `sock_error' field into the SilcSocketConnection
1559 context. When error occurs during socket operation (read
1560 or write) the error is saved. Added also new function
1561 silc_socket_get_error to return human readable socket error
1562 message. Affected files are lib/silcutil/silcsockconn.[ch],
1563 lib/silcutil/unix/silcunixsockconn.c, and
1564 lib/silcutil/win32/silcwin32sockconn.c.
1566 * The server now prints the socket error message in the
1567 signoff for client. Affected file silcd/server.c.
1569 * Fixed the `created' channel information sending from router
1570 to server in JOIN command. Checks now whether the channel
1571 really was created or not and set it according that.
1573 Fixed the JOIN command to use the client entry's current
1574 ID during the joining procedure instead of the one it sent
1575 in the command (it is checked though), since it can change
1576 between the packet processing and command processing, and
1577 would just case unnecessary pain in the client end. Affected
1578 file silcd/command.c.
1580 * Fixed a channel key payload sending to use correct channel
1581 ID when the server was forced to change the channel's ID by
1582 router. Router sent the key payload with the old Channel ID.
1583 Affected file silcd/packet_receive.c.
1585 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1587 * Call silc_server_save_channel_key only if the key payload
1588 was provided in the JOIN command's command reply. Affected
1589 file silcd/command_reply.c.
1591 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1593 * Fixed silc_mp_sizeinbase to return the value correctly with
1594 MPI. Affected file lib/silcmath/mp_mpi.c.
1596 * Fixed the stop_server signal to correctly stop the scheduler
1597 and gracefully stop the server when SIGTERM or SIGINT signals
1598 are received. Affected file silcd/silcd.c.
1600 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1602 * Simple handling of TERM and HUP signals. Also added some log
1603 flushing call around. Affected file is
1606 * Fixed small bugs in silclog.c. Now buffering output will take
1607 effect after 10 seconds since startup: This will ensure that
1608 no important startup messages are lost. Also output redirection
1609 will preserve original format ([Date] [Type] message).
1610 Affected file is lib/silcutil/silclog.c.
1612 * Added two options to the config file, in the logging section:
1613 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1614 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1616 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1618 * Do not print the warning about log files not being initialized
1619 more than once to avoid excess logging. Affected file is
1620 lib/silcutil/silclog.c.
1622 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1623 the SIM copying in make install in Makefile.am.pre.
1625 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1627 * Rewritten silclog APIs. Globally interesting changes follows:
1628 silc_log_set_files() changed to silc_log_set_file().
1629 silc_log_set_callbacks() changed to silc_log_set_callback().
1630 ROBOdoc documented silclog header file.
1631 SilcLogCb now returns bool to wether inihibit the default
1632 handler or not (to keep the old behaviour return always TRUE).
1633 The new APIs should also fix the problem of the
1634 silcd_error.log file that was written in the current directory.
1637 Log files streams will remain opened after silc_log_set_file()
1638 call, means less CPU usage notably on high traffic servers.
1639 File streams are now full buffered, and flushed to the disk
1640 every 5 minutes, lesses HD activity and CPU usage.
1641 Messages can be redirected, allowing admins to configure
1642 one single logfile for all server messages.
1643 the silc_log_quick global variable to activate fast-logging.
1644 Affected files lib/silcutil/silclog.[ch]
1646 * Changed some code to conform new silclog APIs. Affected
1647 files are doc/example_silcd.conf.in, silcd/server.c
1648 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1651 * Fixed a memory leak that could occur in some situations.
1652 Affected file silcd/serverconfig.c.
1654 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1656 * Added the silc_client_del_client to remove the client from
1657 all channels as well. Affected file lib/silcclient/idlist.c.
1659 * Fixed the client library to correctly remove the client
1660 from all channels when the client entry is being destroyed.
1661 Affected file lib/silcclient/client_notify.c, command.c.
1663 * Added auto-nicking support to the client library. If the
1664 applicatio now sets client->nickname it will be sent to the
1665 server after connecting by the library. This way for example
1666 SILCNICK (or IRCNICK) environment variables will have effect
1667 and always change the nickname automatically to whatever
1668 it is wanted. Affected file lib/silcclient/client.[ch].
1670 * Renamed silc_server_command_bad_chars to the
1671 silc_server_name_bad_chars and moved it to the
1672 silcd/server_util.[ch]. Added also new function
1673 silc_server_name_modify_bad to return nickname that
1674 includes bad characters as new nickname without those
1675 bad characters. This check and modify is now used in
1676 silc_server_new_client when the username is initially set
1677 as nickname, so it must be checked to be valid nickname.
1678 Affected file silcd/packet_receive.c.
1680 * The nickname length is now taken from the packet for real
1681 and not trusted to strlen() since it clearly can return
1682 wrong length for nickname including bad characters. This
1683 also applies to channel names. Affected file silcd/command.c.
1685 * Removed the lib/silcsilm/modules directory. Modules are now
1686 compiled into the lib/silcsim. Fixed the copying of the
1687 modules to follow symbolic links in Makefile.am.pre.
1689 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1691 * Fixed silc_string_regexify list creation. Fixes bugs with
1692 BAN and INVITE commands in server. The affected file is
1693 lib/silcutil/unix/silcunixutil.c.
1695 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1697 * Removed the command destructor entirely from the server's
1698 command and command reply routines. It is not needed, and
1699 its usage was buggy and caused crashes. Affected files are
1700 silcd/command[_reply].[ch].
1702 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Cancel protocol and NULL sock->protocol if timeout
1705 occurred during protocol. Affected file silcd/server.c.
1707 * Cancel protocol timeouts always before calling the final
1708 callback, to assure that after final callback is called
1709 no other state will be called for the protocol anymore.
1710 Affected file silcd/protocol.c.
1712 * Print error log if incoming connection configuration could
1713 not be found. Affected file silcd/server.c.
1715 * Fixed JOIN command to correctly save the founder mode
1716 to the client on normal SILC server, when the channel
1717 was created by the router. Affected file silcd/command.c.
1719 * Fixed LIST command (hopefully) to send correct reply
1720 packets. Affected file silcd/command.c.
1722 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * The silc_packet_receive_process now returns FALSE if the
1725 read data was invalid packet, and TRUE if it was ok.
1727 The server now checks that if unauthenticated connection
1728 sends data and its processing fails the server will close
1729 the connection since it could be a malicious flooder.
1731 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1733 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Make sure the warning about error opening a log file is
1736 printed only once and not everytime it fails (produces
1737 too much useless log). Affected file lib/silcutil/silclog.c.
1739 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1741 * Made the silc_server_daemonise() function more readable.
1742 Affected file silcd/server.c.
1744 * Pid file is now optional, the user may comment it out from
1745 the config file. Removed define SILC_SERVER_PID_FILE, we
1746 don't need a default any longer. Affected file
1747 configure.in.pre, lib/Makefile.am.pre.
1749 * Make some use of the pid file. The server now dies at startup
1750 if it detects a valid pid file on his path. The server would
1751 die anyway in this circumstance, because of the bind() failure.
1752 Affected file silcd/silcd.c.
1754 * No longer compiling lib/dotconf.
1756 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1758 * Fixed JOIN command parsing not to crash. Affected file
1759 lib/silcclient/command.c.
1761 * Fied the NICK_CHANGE notify to add the new client entry
1762 even it is resolved. This removes an <[unknown]> nick
1763 thingy bug in the client. Affected file is
1764 lib/silcclient/client_notify.c.
1766 * Do not try to allocate 0 bytes (efence does not like it)
1767 in lib/silccore/silccomand.c when encoding payload.
1769 * Do not take IRCNICK as nickname in Irssi SILC client since
1770 it is not possible to set nickname before hand connecting
1771 the server (TODO has an entry about adding auto-nicking
1774 * Changed the silc_server_command_pending to check whether
1775 there already exists an pending entry with the specified
1776 command, command identifier and pending callback. This is
1777 to fix IDENTIFY and WHOIS related crashes that may register
1778 multiple pending commands with same identifier. Affected
1779 file silcd/command.c.
1781 * Fixed the server to reconnect to the router even if it
1782 was already reconnecting and EOF was received. This to
1783 fix a possibility that the server wouldn't ever try to
1784 auto-reconnect to the router. Affected file silcd/server.c.
1786 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1788 * Fixed the server's password authentication to use the
1789 length of the locally saved password, and not the one
1790 sent in the packet. Affected file silcd/protocol.c.
1792 * Fixed same password authentication problem in the
1793 Authentication Payload handling routines in
1794 lib/silccore/silcauth.c.
1796 * Yet another password authentication problem fixed with
1797 channel password handling in silcd/command.c.
1799 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1801 * If first character of string in silc_parse_userfqdn is '@'
1802 then do not parse it. Affected file is
1803 lib/silcutil/silcutil.c.
1805 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1807 * Fixed minor bug in IDENTIFY command reply sending, which
1808 caused various weird problems during JOIN when it was
1809 resolving names for users. Affected file silcd/command.c.
1811 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1813 * Fixed the IDENTIFY command reply sending to chech better valid
1814 clients. It was possible to send incomplete list of replies.
1815 Affected file silcd/command.c.
1817 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1819 * Added silc_client_command[s]_[un]register functions now to
1820 dynamically register the commands in client library. Removed
1821 the static table of commands. This allows the client library
1822 to call commands without causing the application to know about
1823 what commands library has called.
1825 Removed the INFO command reply kludge to detect when the command
1826 was called by library. Now library use its own command reply
1827 function for INFO command.
1829 Added function silc_client_command_call to call a command.
1830 Application can use it to call command, not access the structure
1833 Now all commands that are sent by the client library (not
1834 explicitly sent by application) use own command reply functions.
1836 Affected files around lib/silcclient/ and in
1837 irssi/src/silc/core/.
1839 * Fixed the WHOIS command reply sending to chech better valid
1840 clients. It was possible to send incomplete list of replies.
1842 Fixed the WHOIS and IDENTIFY to send the request to router
1843 if normal server did not do it and did not find any results.
1845 Affected file silcd/command.c.
1847 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Moved the internal data from SilcClient context into its
1850 own file, not accesible to application. Affected files
1851 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1852 and other files in client library.
1854 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Added doc/examples installation target in Makefile.am.pre.
1859 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1861 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1862 commands the found client entry will be removed from the
1863 cache, after notifying application about the error. Affected
1864 file lib/silcclient/command_reply.c.
1866 * Changed the /MSG to check for exact nickname user gave, and
1867 not let `nick' match `nick@host' if it is only one found. Now,
1868 user must type the exact nickname (like nick@host2) even if
1869 there are no more than one same nicks found. This is to avoid
1870 a possibility of sending nickname to wrong nickname since
1871 `nick' could match `nick@host'. Affected file is
1872 irssi/src/core/silc-servers.c.
1874 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1876 * Do not print "you are now server operator" or similar when
1877 giving /away command. Affected files are
1878 irssi/src/silc/core/client_ops.c, silc-servers.h.
1880 * Made the silc_server_command_pending_error_check to send
1881 the same command reply payload it received back to the
1882 original sender of the command. This way all arguments
1883 that was received by the server will be received by the
1884 client too. Affected file silcd/command.c.
1886 * Added the silc_idcache_add to return the created cache entry
1887 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1889 * Add global clients to expire if they are not on any channel.
1890 This is because normal server will never know if they signoff
1891 if they are not on any channel. The cache expiry will take
1892 case of these entries. This is done by normal servers only.
1893 The affected files are silcd/command_reply.c,
1894 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1896 * If server receives invalid ID notification for WHOIS or
1897 IDENTIFY and the ID exists in the lists, it is removed.
1898 Affected file silcd/command_reply.c.
1900 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1901 in client then client entry that it matches is searched and
1902 the nickname is printed on the screen for user. Affected
1903 file irssi/src/silc/core/client_ops.c.
1905 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1907 * Use cache entry expire time in the LIST command reply to
1908 purge old entries from the cache after the LIST command
1909 reply has been received. This way we don't have non-existent
1910 entries in the cache for too long. Affected file is
1911 silcd/command_reply.c.
1913 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1915 * If we are normal server, and we've not resolved client info
1916 in WHOIS or IDENTIFY from router, and it is global client,
1917 we'll check whether it is on some channel. If it is not
1918 then we cannot be sure about its validity and will resolve it
1919 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1920 file silcd/command.c.
1922 * Search channel by name (if possible) rather than by ID
1923 in IDENTIFY command's command reply. Affected file is
1924 silcd/command_reply.c.
1926 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1928 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1929 Updated specs and implemented it. Affected file silcd/command.c,
1930 silcd/packet_send.c and silcd/packet_receive.c.
1932 * Implemented the <founder auth> payload handling in the JOIN
1933 command. If provided all conditions for channel joining
1934 except requirement to provide correct passphrase can be
1935 overrided by the channel founder. Updated the protocol specs.
1936 Affected file silcd/command.c.
1938 Added support for founder auth in JOIN command in client
1939 library. Fixed the parsing of the JOIN command now to support
1940 all options as they should be. The affected file is
1941 lib/silcclient/command.c.
1943 * Optimized the WHOIS and IDENTIFY commands to send the request
1944 to router only if it includes nicknames or other names. If
1945 they include only IDs then check the local cache first before
1946 routing. Affected file is silcd/command.c.
1948 * Added channels topic announcements. Affected file is
1949 silcd/packet_receive.c and silcd/server.c.
1951 * Fixed the silc_server_send_notify_topic_set to really destine
1952 the packet to channel. Affected file silcd/packet_send.c.
1954 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1955 library. Affected file lib/silcclient/client_notify.c.
1957 * Added UMODE announcements. Affected file silcd/server.c.
1959 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Memory leak fixes in:
1963 lib/silcutil/silcsockconn.c
1964 lib/silcske/silcske.c
1965 lib/silcske/groups.c
1967 lib/silccrypt/silcpkcs.c
1968 lib/silccore/silccommand.c
1969 lib/silccore/silcidcache.c
1974 * ROBOdoc documented the lib/silcske/groups.h file and a
1975 bit changed the interface for better.
1977 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1979 * Update the client entry context in the ID cache after
1980 nick change. Affected file lib/silcclient/command.c.
1981 Fixes the CUMODE command when regaining founder privileges,
1982 and a little WHOIS problem.
1984 * Fixed silc_net_gethostbyname to correctly call the
1985 inet_ntop. Affected file lib/silcutil/silcnet.c.
1987 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1989 * Added IPv6 support checking to the configure.in.pre, added
1990 also --enable-ipv6 option to override the check. Affected
1991 file configure.in.pre.
1993 * The silc_thread_create now calls the start function
1994 directly if threads support is not compiled in. Removes
1995 ugly #ifdef's from generic code. Affected files are
1996 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1998 * Added silc_net_gethostby[name/addr]_async to asynchronously
1999 resolve. Affected files are lib/silcutil/silcnet.[ch].
2001 * Added support for rendering IPv6 based server, client and
2002 channel IDs. Affected file lib/silcutil/silcutil.c.
2004 * Added support for creating IPv6 based server IDs. Affected
2005 file is silcd/serverid.c.
2007 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2009 * Added silc_net_gethostby[addr/name] into the
2010 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2011 routines. Added silc_net_is_ip[4/6]. Affected file is
2012 lib/silcutil/unix/silcunixnet.c. All routines that take
2013 address as argument now supports both IPv4 and IPv6 addresses.
2015 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2017 * Fixed LIST command reply sending in server. Affected file
2020 * Server now sends the kicker's client ID in the KICK notify
2021 to the kicked client. Affected file silcd/command.c.
2023 * The client library now parses the kickers client ID and
2024 UI displays it. Affected files lib/silcclient/client_notify.c
2025 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2027 * Made all payload parsing function prototypes consistent.
2028 They all take now const unsigned char * and uint32 pair as
2029 the payload data instead of SilcBuffer. Changes all around
2030 the source tree. Other unsigned char* -> const unsigned char*
2031 changes around the tree as well.
2033 * Optimized SFTP client and server packet sending not to
2034 allocate new buffer for each packet but to recycle the
2035 first allocated buffer. Affected files are
2036 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2038 * Optimized the SFTP client to use SilcList instead of
2039 SilcDList for requests, because it is faster. Affected file
2040 is lib/silcsftp/sftp_client.c.
2042 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2043 into lib/silccore/silcid.[ch].
2045 Renamed silcpayload.[ch] into silcargument.[ch].
2047 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * If client entry is deleted with active key agreement
2050 session, abort the session.
2052 The silc_client_abort_key_agreement now calls the completion
2053 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2055 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2058 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2060 * Don't use __restrict in older GCC's. Affected file is
2061 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2063 * silc_net_localhost now attempts to reverse lookup the
2064 IP/hostname. Affected file lib/silcutil/silcnet.c.
2066 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2067 command. It can be used to gain founder privileges at
2068 the same time when joining the channel.
2070 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2071 kicker's client ID as well. Updated protocol specs.
2073 Defined that the server must send SILC_COMMAND_IDENTIFY
2074 command reply with error status to client who sent
2075 private message with invalid client ID.
2077 Updated the protocol specification.
2079 * Added silc_server_send_command_reply to send any
2080 command reply. Affected file silcd/packet_send.[ch].
2082 * Added silc_id_payload_encode_data to encode ID payload
2083 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2085 * The server now send IDENTIFY command reply with error
2086 status if client ID in private message is invalid. Affected
2087 file silcd/packet_receive.c.
2089 * Save the server key file with server's IP address in
2090 the filename instead of hostname. The affected file is
2091 irssi/src/silc/core/client_ops.c.
2093 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2098 * Added libtool support for compiling shared objects in
2099 lib/silcsim. Affected file configure.in.pre and
2100 lib/silcsim/Makefile.am. Original patch by cras.
2102 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2104 * Pid file configuration, and server's config file fixes
2105 patch by toma. Updated CREDITS file.
2107 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2109 * Fixed silc_client_channel_message to not try to decrypt
2110 the message twice if it resolved the destination client
2111 information. This could cause of dropping one channel
2112 message. Affected file lib/silcclient/client_channel.c.
2114 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2116 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2117 lib/silcclient/client.c. This function is used when the SILC
2118 Client is run under some other scheduler, or event loop or
2119 main loop. On GUI applications, for example this may be
2120 desired to used to run the client under the GUI application's
2121 main loop. Typically the GUI application would register an
2122 idle task that calls this function multiple times in a second
2123 to quickly process the SILC specific data.
2125 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2127 * Fixed silc_server_drop() for dropping the supplementary
2128 groups as well, this could cause a security hole on some
2131 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2136 * Write PID file after dropping privileges. Added -F option
2137 to run server on foreground. A patch by debolaz.
2138 Affected files silcd/server.c, silcd/silcd.c.
2140 * Fixed MOTD to return the MOTD file server name. Affected
2141 file silcd/command.c.
2143 * Added INFO command reply handling to the Irssi SILC Client.
2144 Affected file irssi/src/silc/core/client_ops.c.
2146 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2148 * Fixed the silc_idcache_list_* routines to really support
2149 the dynamic list. Fixes a crash. Affected file is
2150 lib/silccore/silcidcache.c.
2152 * Fixed the LIST command reply to really call LIST command's
2153 pending callbacks. Affected file silcd/command_reply.c.
2155 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2157 * Update conn->local_entry->nickname after giving NICK
2158 command. Affected file lib/silcclient/command.c.
2160 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2162 * Added the [pid] option to the silcd configuration file
2164 Affected files: serverconfig.[ch] and silcd.c
2166 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Save fingerprint in WHOIS command reply in server.
2169 Affected file silcd/command_reply.c.
2171 * Fixed NICK commands pending callback registration.
2172 Affected file lib/silcclient/command.c.
2174 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Use ++server->cmd_ident when sending commands in server,
2177 instead of random number. Affected file silcd/command.c.
2179 * Fixed GETKEY command reply to call actually GETKEY pending
2180 command callbacks. Affected file silcd/command_reply.c.
2182 * A bit stricter check for nicknames. Check for same nickname
2183 in NICK command also. Affected file silcd/command.c.
2185 * Do not call INFO command everytime client ID changes, only
2186 during first connecting. Affected file lib/silcclient/client.c.
2188 * Set the new nickname only after successful command reply for
2189 NICK command is returned by server. Affected file
2190 lib/silcclient/command.c.
2192 * Remove nicknames from nicklist during server_signoff notify.
2193 Should fix /NAMES bit more. The affected file is
2194 irssi/src/silc/core/silc-channels.c.
2196 * Added `fingerprint' field to the SilcIDListData in the
2197 silcd/idlist.h to hold the fingerprint of the client's
2200 Send the fingerprint of the client's public key in WHOIS
2203 Affected files silcd/command.c, and silcd/idlist.[ch].
2205 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2206 create fingerprint from given data.
2208 * Show the fingerprint of the client's public key in WHOIS.
2209 Affected files irssi/src/module-formats.[ch] and
2210 irssi/src/silc/core/client_ops.c.
2212 * Format the multiple same nicknames also during JOIN and
2213 NICK_CHANGE notifys. Affected file is
2214 lib/silcclient/client_notify.c.
2216 * Do not print error on screen for invalid private message
2217 payload since it can come if someone is sending private
2218 messages with wrong key. Affected file
2219 lib/silccore/silcprivate.c.
2221 * Fixed multiple concurrent /PING crash. Affected file
2222 lib/silcclient/command.c.
2224 * Changed the wrong ID encoding. All IP addresses must be
2225 in MSB first order in encoded format. They were encoded
2226 wrong and was in LSB format. Affected files are
2227 silcd/serverid.c, lib/silcutil/silcutil.c.
2229 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2231 * Call the `connect' client operation through the scheduler
2232 in case of error. Affected file lib/silcclient/client.c.
2234 * Call the `failure' client operation even if the error
2235 occurred locally during a protocol. Affected file is
2236 lib/silcclient/protocol.c.
2238 * Added support of sending LIST command to router from normal
2239 server. This way normal server can get list of all channels
2240 in the network too. Fixed the channel list sending in the
2241 server too. Affected files are silcd/command.c, and
2242 silcd/command_reply.[ch].
2244 * Added silc_server_update_channels_by_server and
2245 silc_server_remove_channels_by_server. They are used during
2246 disconnection of primary router and in backup router protocol.
2247 Affected file silcd/server_util.[ch], silcd/server.c and
2248 silcd/server_backup.c.
2250 * Fixed channel adding to global list in IDENTIFY command
2251 reply in server. Affected file silcd/command_reply.c.
2253 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2255 * If the incoming packet type is REKEY or REKEY_DONE process
2256 that packet always synchronously. Fixes yet another MAC
2257 failed error on slow (dialup) connections. Affected file
2258 lib/silcclient/client.c and silcd/server.c.
2260 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Call check_version SKE callback for initiator too. Affected
2263 file lib/silcske/silcske.c.
2265 * Implemented fix for security hole found in the SKE that was
2266 fixed in the specification few days back; the initiator's
2267 public key is now added to the HASH value computation.
2268 Added backwards support for the old way of doing it too, for
2269 old clients and old servers. Affected file is
2270 lib/silcske/silcske.c.
2272 * Enabled mutual authentication by default in SKE. If initiator
2273 is not providing mutual authentication the responder will
2274 force it. This will provide the proof of posession of the
2275 private key for responder. The affected files are
2276 lib/silcclient/protocol.c and silcd/protocol.c.
2278 * Do not cache anymore the server's public key during SKE.
2279 We do mutual authentication so the proof of posession of
2280 private key is done, and if the server is authenticated in
2281 conn auth protocol with public key we must have the public
2282 key already. Affected file silcd/protocol.c.
2284 * Added new global debug variable: silc_debug_hexdump. If
2285 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2286 file lib/silcutil/silclog.[ch].
2288 * Fixed compilation warning due to char * -> const char *.
2289 Affected files lib/silcutil/silcnet.h, and
2290 lib/silccore/silcauth.[ch].
2292 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Fixed CMODE command when new channel key was created. If
2295 the creation failed the old key was removed. Next time giving
2296 same command would crash the server since the old key was
2297 freed already. Affected file silcd/command.c.
2299 * Fixed the silc_server_announce_get_channels to not crash
2300 on reconnect. Affected file silcd/server.c.
2302 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2304 * Added silc_log_set_debug_string function to set a regex
2305 string to match for debug output. Only the function names,
2306 or filenames matching the given debug string is actually
2307 printed. This way it is possible to filter out those debug
2308 strings that user is not interested in.
2310 Fixed a bug in silc_string_regexify.
2312 Affected files lib/silcutil/silclog.[ch], and
2313 lib/silcutil/unix/silcunixutil.c.
2315 * Changed the -d options in both server and Irssi SILC client
2316 to take the debug string as argument. Affected files
2317 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2319 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Added silc_hash_babbleprint to create a Bubble Babble
2322 Encoded fingerprint. The encoding is developed by Antti
2323 Huima (draft-huima-babble-01.txt), and it creates human
2324 readable strings out of binary data. Affected file
2325 lib/silccrypt/silchash.[ch].
2327 * Print the babble print now in addition of fingerprint as well
2328 in Irssi SILC client. Affected files are
2329 irssi/src/fe-common/silc/module-formats.[ch],
2330 irssi/src/fe-common/silc/core/client_ops.c.
2332 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2334 * Fixed a security problem found in SKE. The initiator's
2335 public key too is now added to the HASH hash value creation
2336 which is signed by the responder to create the SIGN value.
2337 This will prevent anyone in the middle to lie to the responder
2338 about the initiator's public key. If this is done now, the
2339 man in the middle will get caught. Updated the protocol
2342 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Better installation directory handling. Configure module
2345 paths and other paths automatically to example_silc* files
2346 in doc/. A patch by toma.
2348 * Fixed compiler warning from MPI library, and from SILC RNG.
2351 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2352 It can be configured with ./configure. A patch by toma.
2354 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Find correct make to use in prepare-clean. A patch by
2357 toma. Affected file prepare-clean.
2359 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2361 * Added irssi variables use_auto_addr, auto_bind_ip,
2362 auto_bind_port and auto_public_ip.
2364 * Changed the interface for silc_client_send_key_agreement
2365 in lib/silcclient/silcapi.h
2369 irssi/src/silc/core/silc-core.c
2371 lib/silcclient/silcapi.h
2372 irssi/src/silc/core/silc-channels.c
2373 lib/silcclient/client_keyagr.c
2376 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Added silc_pkcs_public_key_compare to compare two
2379 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2381 * Check that the client who set the founder mode on the
2382 channel is the same client that is giving the founder
2383 mode to itself. It is done by comparing the saved public
2384 key (it is saved even in the authentication is passphrase).
2385 Affected file silcd/command.c.
2387 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Do not process packet for disconnected socket connection.
2390 Affected file lib/silccore/silcpacket.c.
2392 * Process the DISCONNECT packet through scheduler in the
2393 client library. Affected file lib/silcclient/client.c.
2395 * Fixed the silc_client_packet_parse to not to increase
2396 the packet sequence number if the conn->sock and the
2397 current socket connection is not same. This can happen
2398 for example during key agreement when the conn includes
2399 multiple socket connections (listeners). Affected file
2400 lib/silcclient/client.c.
2402 * The sender of the file transfer request now provides also
2403 the pointer (listener) for the key exchange protocol. If
2404 the listener cannot be created then it sends empty key
2405 agreement and lets the receiver provide the listener.
2407 Added `local_ip' and `local_port' arguments to the
2408 silc_client_file_send. If they are provided they are used,
2409 if not then it will attempt to find local IP address, if
2410 not found or bind fails then the remote client will provide
2413 Affected files are lib/silcclient/client_ftp.c and
2414 lib/silcclient/silcapi.h.
2416 * Extended the FILE SEND command to support defining the
2417 local IP and port for key exchange listener. They are
2418 optional. Affected file irssi/src/silc/core/silc-servers.c.
2420 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2422 * Defined to WHOIS command reply the sending of fingerprint
2423 of the client's public key (if the proof of posession of the
2424 corresponding private key is verified by the server).
2425 Updated to the protocol specification.
2427 * Added support of receiving the client's public key's
2428 fingerprint in command reply in client library. Affected
2429 file is lib/silcclient/command_reply.c, and
2430 lib/silcclient/idlist.[ch].
2432 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Do not send over 128 chars long nickname to the server
2435 in NICK command. Affected file lib/silcclient/command.c.
2437 * Do not send over 256 chars long channel names to the server
2438 in JOIN command. Affected file lib/silcclient/command.c.
2440 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2442 * Assure that silc_server_close_connection cannot be called
2443 twice for same socket context. Affected file is
2446 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Send error message to application if opening file for
2449 writing during file transfer fails. Affected file is
2450 lib/silcclient/client_ftp.c.
2452 Remove all file transfer sessions for a client that we're
2453 removing from ID cache.
2455 Affected file is lib/silcclient/client_ftp.c.
2457 * Fixed silc_net_addr2bin to return correct address. Affected
2458 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2460 * Fixed file transfer session removing on signoff notify.
2461 Affected file irssi/src/silc/core/silc-servers.c.
2463 * Added the SilcClientFileError to be returned in the monitor
2464 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2465 Affected file lib/silcclient/silcapi.h.
2467 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Fixed a crash in silc_client_ftp_free_sessions and
2470 silc_client_ftp_session_free_client. Affected file
2471 lib/silcclient/client_ftp.c.
2473 * Added `disabled' field in the SilcChannelEntry in the server
2474 to indicate if the server entry is disabled. Affected file
2475 silcd/idlist.h, silcd/command[_reply].c.
2477 * SILC server adds now /var/run/silcd.pid everytime it is
2478 started. Affected file silcd/silcd.c.
2480 * Added silc_server_packet_send_clients to send a packet to
2481 the provided table of client entries. Affected file
2482 silcd/packet_send.[ch].
2484 * Fixed a crash in client resolving in client_prvmsg.c in
2485 client library. Affected file lib/silcclient/client_prvmsg.c.
2487 * Do not actually remove the client directly from ID cache
2488 during SERVER_SIGNOFF, but invalidate it. This way we
2489 preserve the WHOWAS info for the client. Affected file
2490 silcd/server_util.c.
2492 * Fixed SERVER_SIGNOFF notify handling in the server. The
2493 server is now able to process incoming SERVER_SIGNOFF notify
2494 for a server that it doesn't even know about. It will remove
2495 the clients provided in the notify. Affected file
2496 silcd/packet_receive.c.
2498 * Check for partial packet in data queue after every packet that
2499 was found from the queue. Return and wait for more data if
2500 there is partial data in queue. Affected file is
2501 lib/silccore/silcpacket.c.
2503 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * Added SilcClietFileError enum to indicate error in
2506 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2507 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2508 Affected files lib/silcclient/silcapi.h and
2509 lib/silcclient/client_ftp.c.
2511 * Check that newsize in silc_buffer_realloc is larger than
2512 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2514 * Added better monitor of file transfers. It now monitors
2515 key agreement protocol during the file transfer too. Added
2516 error reporting too. Affected files
2517 irssi/src/silc/core/silc-servers.c,
2518 irssi/src/fe-common/silc/module-formats.[ch].
2520 * Wrote a help file for FILE command.
2522 * Added silc_rng_global_get_byte_fast to get not-so-secure
2523 random data as fast as possible. Random data is read from
2524 /dev/urandom if available and from the SILC RNG if not
2525 available. It is used in padding generation. Affected file
2526 lib/silccrypt/silcrng.[ch].
2528 * All packets in client library are now processed synchronously.
2529 Optimized packet processing a lot. Affected file
2530 lib/silcclient/client.c.
2532 * All server connection packets are processing synchronously
2533 now in server, to optimize packet processing. Affected file
2536 * Include files are installed now only in Toolkit distribution
2537 if make install is given. Affected files: all Makefile.am's.
2539 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2541 * Assure that silc_client_notify_by_server_resolve does not
2542 resolve the client information multiple times. If it cannot
2543 be found by the first it cannot be found at all. Affected
2544 file lib/silcclient/client_notify.c.
2546 * Fixed WHOWAS command reply calling. Affected file
2547 lib/silcclient/command_reply.c.
2549 * Removed all references to silc_idlist_get_client from the
2550 Irssi SILC client since that call is internal call used by
2551 the library. The Irssi SILC client will use now client
2552 retrieval functions found in silcapi.h.
2554 * Fixed a bug in resolving nickname info before sending
2555 private message. It used freed memory. Affected file
2556 irssi/src/silc/core/silc-servers.c.
2558 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2560 * Assure my_channels statistics cannot go negative in server.
2561 Affected files silcd/server.c, silcd/server_util.c.
2563 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2567 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2569 * Win32 Toolkit changes. Affected files
2570 win32/silc.dsw, win32/libsilc/libsilc.def,
2571 win32/libsilcclient/libsilc.def,
2572 lib/silcutil/silcutil.c, and
2573 lib/sftp/sftp_fs_memory.c.
2575 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2577 * Added silc_net_localip to return local host's IP address.
2578 Affected file lib/silcutil/silcnet.[ch].
2580 * If key exchange or rekey protocol is active for a connection
2581 parse all packets syncronously since there might be packets
2582 in packet queue that we are not able to process without first
2583 processing packets before them. Affected file silcd/server,
2584 lib/silcclient/client.c.
2586 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2587 whether library should continue processing the packet.
2588 Affected file lib/silccore/silcpacket.h.
2590 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2591 SilcSFTPMonitorData to SFTP server to monitor various
2592 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2593 lib/silcsftp/sftp_server.c.
2595 * Added silc_file_size to return file size. Affected file
2596 lib/silcutil/silcutil.[ch].

2599 Added preliminary support for simple client to client one-file
2600 transmission. Affected file lib/silcclient/client_ftp.c,
2601 lib/silccilent/client.[ch].
2603 * Added new local command FILE to the Irssi SILC Client.
2604 It is used to perform the file transfer. It has subcommands
2605 SEND, RECEIVE, SHOW and CLOSE. Affected files
2606 irssi/src/silc/core/client_ops.c,
2607 irssi/src/silc/core/silc-server.[ch].
2609 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Relay the SILC_PACKET_FTP in the server. Affected files
2612 silcd/server.c and silcd/packet_receive.c.

2616 * Renamed silc_file_read and silc_file_write to functions
2617 silc_file_readfile and silc_file_writefile. Added function
2618 silc_file_open and silc_file_close. Affected files
2619 lib/silcutil/silcutil.[ch].
2621 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Resolve the client info when received private message or
2624 channel message for a client which nickname we don't know.
2625 Affected files lib/silcclient/client_prvmsg.c and
2626 lib/silcclient/client_channel.c.
2628 * Do not crash in /KEY if client is not connected. Affected
2629 file irssi/src/silc/core/silc-channels.c.
2631 * Added SilcClientStatus field to the SilcClientEntry in the
2632 lib/silcclient/idlist.h.
2634 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2635 is incomplete and is being resolved, it won't be resolved
2638 Make sure also that USERS command reply does not resolve
2639 twice information. Affected file is
2640 lib/silcclient/command_reply.c.
2642 Make sure that silc_client_get_clients_by_list does not
2643 resolve twice same information.
2645 * Check for valid client->id in the silc_server_free_client_data.
2646 Affected file silcd/server.c.
2648 * Fixed /GETKEY nick@server not to crash if the server entry
2649 is not found. Affected file lib/silcclient/command.c.
2651 * Fixed the silc_server_check_cmode_rights to check the
2652 requested modes correctly. Affected file silcd/command.c.
2654 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2656 * Better checks for non-printable chars in nick added.
2657 Affected file silcd/command.c.
2659 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2661 * Call the silc_server_udpate_servers_by_server in the
2662 primary router that comes back online in the backup resuming
2663 protocol. Otherwise it routes packets wrong. Affected file
2664 silcd/server_util.[ch], silcd/server_backup.c.
2666 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2669 lib/silcutil/silcbuffmt.[ch].
2671 * Redefined the SILC packet header to include the padding
2672 length. Affected file lib/silccore/silcpacket.[ch].
2674 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2675 length for maximum padding up to 128 bytes). Affected
2676 file lib/silccore/silcpacket.h.
2678 * Removed all backwards support for old 0.5.x MAC thingies.
2679 The SILC packet header change makes it impossible to be
2680 backwards compatible.
2682 * Send the ENDING packet with timeout in the backup resuming
2683 protocol. This is to assure that all routers has connected
2684 to the primary router. Affected file silcd/server_backup.c.
2686 * Changed the RNG to take the first IV from random data. It
2687 used to take it from zero actually. Changed the RNG also
2688 to use /dev/urandom during session. /dev/random is used
2689 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2691 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2693 * Changed the SILC packet header to have the first two bytes
2694 (the packet length) encrypted. Affected files aroung the
2695 code tree, lib/silccore/silcpacket.[ch]. Removed the
2696 SilcPacketCheckDecrypt callback. It is not needed anymore
2697 since the silc_packet_receive_process will determine now
2698 whether the packet is normal or special.
2700 * Implemented the unidirectional MAC keys. Affected files
2701 lib/silcske/silcske.c, silcd/protocol.c and
2702 lib/silcclient/protocol.c.
2704 * Implemented the packet sequence number to the MAC computation.
2705 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2706 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2707 lib/silcclient/protocol.c.
2709 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Allow backup router to announce servers. All servers
2712 announced by backup router are added to the global list
2713 automatically. Update hte server's socket to our primary
2714 router also when backup router announces a server.
2715 Affected file silcd/packet_receive.c.
2717 * Do not update the client->router in the function
2718 silc_server_udpate_clients_by_server if the client is on
2719 global list. We might fail to find any specific server
2720 for locally connected clients and local cell clients. They
2721 should still use the `from' and not `to' as client->router.
2722 This fixes backup router resuming protocol. Affected file
2723 silcd/server_util.c.
2725 * Decrease channel statistics count only if the channel
2726 deletion worked. Affected files are silcd/server.c and
2727 silcd/server_util.c.
2729 * Added silc_server_update_servers_by_server to update origin
2730 of all server entries. Used during backup router protocol.
2731 Affected files silcd/server_util.[ch], silcd/server.c. and
2732 silcd/backup_router.c.
2734 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2735 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2736 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2737 lib/silccrypt/silchmac.c.
2739 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Assure that router cannot reroute the same channel message
2742 to the sender. Affected file silcd/packet_receive.c.
2744 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * Made better checks that the channel message is not sent
2747 to the router it came from. Affected file is
2748 silcd/packet_send.c. Fixed memory leak too.
2750 * Announce informations for incoming router connection, but
2751 only after checking if it is replaced by backup router.
2752 Affected file silcd/packet_receive.c.
2754 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2756 * Fixed the backup resuming protocol to work in multiple
2757 router environment. Affected file silcd/server_backup.c.
2759 * Route packet only to one router in the function
2760 silc_server_packet_send_to_channel. Affected file is
2761 silcd/packet_send.c.
2763 * Fixed silc_server_send_notify_dest to set the broadcast
2764 flag. Fixed the silc_server_send_notify_topic to actually
2765 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2766 Affected file silcd/packet_send.c.
2768 * Changed the SFTP Filesystem interface. Changed the
2769 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2770 the filesystem operation function. The SilcSFTPFilesystem
2771 is now a context that is allocated by all filesystem allocation
2772 functions and it already includes the operations structure
2773 and filesystem specific context. It is given as argument
2774 now to the silc_sftp_server_start. This made the interface
2775 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2776 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2778 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Changed the backup router adding and getting interfaces
2781 in the server. The router that will be replaced by the
2782 specified backup router is now sent as argument. Affected
2783 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2786 * Added silc_net_addr2bin_ne to return the binary form of
2787 the IP address in network byte order. Affected files
2788 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2790 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * Check for existing server ID in silc_server_new_server
2793 and in silc_server_connect_to_router_final and remove the
2794 old entry if it exists. Affected file silcd/packet_receive.c,
2797 * Send the channel message always to only one router, either
2798 in upstream or downstream. Affected file is
2799 silcd/packet_send.c.
2801 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2803 * Wrote the definition of the backup resuming protocol to the
2804 protocol specification.
2806 * Removed one redundant channel key generation from normal
2807 server during joining procedure. Removed one redundant
2808 channel key sending from server to router during joining
2809 procedure. Affected file silcd/command.c.
2811 * Made minor bugfixes to the backup router resuming protocol.
2812 Affected file silcd/server_backup.c, server.c.
2814 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2816 * Added --disable-asm configuration option. Affected files
2817 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2820 * Implemented the backup resuming protocol that is used to
2821 resume the primary router position in the cell after the
2822 primary router comes back online. Affected files
2823 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2824 and silcd/server_util.[ch].
2826 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2828 * Sleep two (2) seconds after sending QUIT command to server.
2829 Affected file lib/silcclient/command.c.
2831 * Assure that if outgoing data buffer is pending do not force
2832 send any data. Affected file silcd/packet_send.c.
2834 * Assure that if outgoing data buffer is pending do not force
2835 send any data. Affected file lib/silcclient/client.c.
2837 * Implemented the backup router support when the primary router
2838 goes down. The servers and routers can now use the backup
2839 router as new primary router without loosing connectivity.
2841 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2843 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2844 in the server to indicate disabled entry. All data read
2845 from the connection will be ignored and no data is sent
2846 for entry that is disabled. Affected files are
2847 silcd/idlist.h, silcd/server.c.
2849 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Created SFTP client and server test programs in the
2852 lib/silcsftp/tests directory.
2854 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2856 * Implemented memory filesystem (virtual filesystem) for
2857 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2860 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * Implemented the SFTP (SSH File Transfer Protocol) to the
2863 lib/silcsftp. It includes SFTP client and SFTP server
2866 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2868 * Moved lib/silccore/silcprotocol.[ch] to the
2869 lib/silcutil library.
2871 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2872 take variable argument list pointer as argument. Affected
2873 file lib/silcutil/silcbuffmt.[ch].
2875 * Added silc_buffer_set function that is used to set data
2876 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2877 Affected file lib/silcutil/silcbuffer.h.
2879 * Changed various routines in the core library to use the new
2880 silc_buffer_set instead of allocating new buffer only for
2883 * Added 64-bit value formatting and unformatting support to the
2884 silc_buffer_[un]format routines. Affected file is
2885 lib/silcutil/silcbuffmt.[ch].
2887 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2888 to includes/bitmove.h.
2890 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2892 * Fixed channel user mode saving in client library. Affected
2893 file lib/silcclient/command[_reply].c.
2895 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Defined the file transfer to the SILC Protocol. Added
2898 new packet type SILC_PACKET_FTP and defined File Transfer
2899 Payload. The mandatory file transfer protocol is SFTP
2900 (SSH File Transfer Protocol). Affected file in addition
2901 of the internet draft is lib/silccore/silcpacket.h.
2903 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2904 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2905 is used as part of backup router protocol when the primary
2906 router of the cell is back online and wishes to resume
2907 the position as primary router.
2909 * Redefined the MAC generation keys in the protocol. The
2910 same key is not used anymore in both direction. Both
2911 direction will now use different keys for sending and
2912 receiving. This fixes a potential security flaw. This
2913 change causes incompatibilities in the protocol.
2915 * Redefined also the MAC computation from the packet.
2916 An packet sequence number is now added to the MAC
2917 computation. This prevents possible replay attacks against
2918 the protocol. This change too causes incompatibilities
2921 Added `sequence' field to the SilcPacketContext to hold
2922 the current sequence number for the packet.
2924 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Added `created' field to the SilcIDListData in the file
2927 silcd/idlist.h to indicate the time when the entry was
2930 * Added `created' field to the SilcChannelEntry too. Affected
2931 file silcd/idlist.h.
2933 * Added `creation_time' aguments to all the announcement functions
2934 in the server. If it is provided then only the entries that
2935 was created after the provided time frame are actually
2936 announced. Affected file silcd/server.[ch].
2938 * The protocol says that the Channel ID's IP address must be
2939 based on the router's IP address. Added check for this in
2940 the silc_server_new_channel when processing incoming New Channel
2941 Payload. Affected file silcd/packet_receive.c.
2943 * Print out the correct version with --version in SILC client.
2944 Affected file irssi/src/silc/core/silc-core.c.
2946 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Fixed WHOWAS command to check for completnes of the client
2949 entry always, not just when the command is coming from client.
2950 Affected file silcd/command.c.
2952 * Added new function silc_server_packet_queue_purge to purge the
2953 outgoing data queue to the network. After the function returns
2954 it is guaranteed that the outgoing packet queue is empty.
2955 Affected file silcd/packet_send.[ch].
2957 * Purge the outgoing packet queue in the rekey protocol's final
2958 callback to assure that all rekey packets go to the network
2959 before quitting the protocol. Affected file silcd/server.c.
2961 * Added silc_client_packet_queue_parse as similar function as
2962 in server to the client library. The affected file is
2963 lib/silcclient/client.c.
2965 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Splitted silcd/server.c and created silcd/server_util.[ch]
2968 for utility functions.
2970 * Added new socket flag SILC_SF_DISABLED to indicate that the
2971 connection is open but nothing can be sent to or received from
2972 the connection. Affected file lib/silcutil/silsockconn.[ch].
2973 The checking for disabled socket is checked in the low level
2974 silc_socket_write and silc_socket_read functions.
2976 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2978 * Allow only nicknames and channel names that fits into the
2979 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2981 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * When processing JOIN command reply in server check that if
2984 the channel exists in our global list we'll move it the local
2985 list. Affected file silcd/command_reply.c.
2987 * Fixed the check whether client is joined on the channel already
2988 in JOIN command. Affected file lib/silcclient/command.c.
2990 * Fixed the JOIN command reply to check whether the channel
2991 already exists. Affected file lib/silcclient/command_reply.c.
2993 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Added silc_ske_status_string to map the SKE error numbers
2996 to readable strings. The affected files are
2997 lib/silcske/silcske[_status].[ch].
2999 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Do not show the private channels on the WHOIS channel list
3002 as it is not allowed by the protocol. The affected file is
3005 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3007 * Assure that the packet length digged from the actual packet
3008 is something sensible in the silc_packet_decrypt_rest_special
3009 in lib/silccrypt/silcpacket.c.
3011 * Free and NULL the allocated pointer in silc_hmac_alloc if
3012 the HMAC allocation fails. The affected file is
3013 lib/silccrypt/silchmac.c.
3015 * Print the selected security properties to the log files in
3016 the server. Affected file silcd/protocol.c.
3018 * Add SKE's reference counter even if calling the completion
3019 callback manually. Otherwise it goes negative, although it
3020 does not cause any problems. The affected file is
3021 lib/silcske/silcske.c.
3023 * Remove the client entry with short timeout after giving the
3024 KILL command. Affected file lib/silcclient/command.c.
3026 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3027 case all found clients are already disconnected (WHOWAS would
3028 found them) in the server. Affected file silcd/command.c.
3030 * Update the last_receive (time of last data received) to be
3031 updated only when received private or channel message so that
3032 the idle time showed in WHOIS makes more sense.
3034 * Added boolean field `valid' in to the SilcClientEntry in the
3035 client library to indicate whether the entry is valid or not.
3036 This fixes the nickname change bug on channel when changing
3037 the nickname to be same than the old (like nick to Nick) the
3038 nickname formatter doesn't set the new nick anymore to Nick@host.
3039 Affected file lib/silcclient/idlist.[ch].
3041 * Now actually fixed the nickname changing on disconnection.
3042 Added new function silc_change_nick to the Irssi SILC Client.
3043 Affected file irssi/src/silc/core/client_ops.c,
3044 irssi/src/silc/core/silc-nicklist.[ch].
3046 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Check that the public key exists in the GETKEY command before
3049 trying to encode it. Affected file silcd/command.c.
3051 * Print some notifications on received public keys with GETKEY
3052 command in the Irssi SILC Client. Affected files are
3053 irssi/src/fe-common/silc/module-formats.[ch],
3054 irssi/src/silc/core/client_ops.c.
3056 * Use IDENTIFY command to resolve the server information in the
3057 GETKEY command instead of INFO command. Affected file
3058 lib/silcclient/command.c.
3060 * All command reply functions in the client library now calls
3061 the pending command reply callbacks even if an error has
3062 occurred. The server has done this a long time and now it was
3063 time to move the client library to this as well. Now all
3064 errors can be delivered back to the pending command reply
3065 callbacks if necessary. Affected files are
3066 lib/silcclient/command[_reply].[ch].
3068 * Change the nickname on disconnection back to the username
3069 because in reconnect the server will enforce it to it anyway.
3070 Affected file irssi/src/silc/core/silc-servers.c.
3072 * Fixed a config file parsing bug in the Irssi SILC client.
3073 Affected file irssi/src/silc/core/clientconfig.c.
3075 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * When printing the channel mode on JOIN, verify that the
3078 channel key and channel's HMAC are valid. Affected file
3079 irssi/src/silc/core/client_ops.c.
3081 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3084 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3085 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3087 * Removed channel key rekey task deleting from the function
3088 silc_server_save_channel_key. Affected file silcd/server.c.
3089 Added explicit timeout task context instead that is used to
3090 delete the task if we are registering a new task before the
3091 new task has elapsed.
3093 * When channel key rekey occurs the client library now saves
3094 the old channel key for a short period of time (10 seconds) and
3095 is able to use it in case some is still sending channel
3096 messages encrypted with the old key after the rekey. Affected
3097 file lib/silcclient/[idlist.h|client_channel.c].
3099 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Added check to the silc_server_new_id_real to not accept
3102 new ID if it is the sender's own ID. Affected file is
3103 silcd/packet_receive.c.
3105 * Assure that we do not announce ourself or the one we've
3106 sending our announcements when we're router and are announcing
3107 servers to our primary router. Affected file silcd/server.c.
3109 * Fixed silc_server_command_identify_check_client to assemble
3110 correct WHOIS packet. It send corrupted WHOIS packet and
3111 caused problem with router to router connections. Affected
3112 file silcd/command.c.
3114 Fixed also silc_server_command_whois_check the same way
3115 as for the IDENTIFY command.
3117 * Added new SilcIDListStatus to the server in the SilcIDListData
3118 structure. The status now includes the current status of
3119 the entry (like registered, resolved etc.). Affected file
3120 silcd/idlist.[ch]. Defined a bunch of different status types
3121 as well. This replaced the old boolean registered field as well.
3123 Added resolve_cmd_ident field to the SilcClientEntry structure
3124 too so that if the entry is for example being resolved so
3125 another command may attach to the same pending command reply
3126 without requiring to resolve the same entry again. This concept
3127 should optimize the WHOIS and the IDENTIFY resolving under
3128 heavy load by taking away unnecessary resolving for entries
3129 that are being resolved already.
3131 Added support for adding multiple pending commands for one
3132 command idenfier. Affected file silcd/command[_reply].[ch].
3134 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3135 before deleting the data. Otherwise the hash table will have
3136 freed data in comparison functions. Affected file is
3137 silcd/command_reply.c.
3139 * Fixed silc_idlist_replace_client_id to add the new entry to
3140 the cache with NULL nickname. Otherwise there will be invalid
3141 memory as the nickname after the nickname is freed. Affected
3142 file silcd/packet_receive.c.
3144 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3145 saved into wrong slots because the previous number of entries
3146 was not taken into account. Affected file silcd/idlist.c.
3147 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3149 * If we are router and we receive JOIN notify to a channel that
3150 does not have any users then notified client is marked as the
3151 channel founder, as it is it. The affected file is
3152 silcd/packet_receive.c
3154 * Added to the extended hash table API's table_del_*ext functions
3155 the destructor as argument too, so that the caller can decide
3156 which destructor to use or whether to use destructor at all.
3157 Affected file lib/silcutil/silchashtable.[ch].
3159 * Fixed ID Cache purging. It actually deleted the entries from
3160 the hash table after the data was freed. The hash table ended
3161 up comparing freed memory. The affected file is
3162 lib/silccore/silcidcache.c.
3164 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Fixed Irssi SILC client's KILL command's HELP syntax.
3168 * The USERS command now resolves the detailed user information
3169 if the userinfo field is missing. Affected file is
3170 lib/silcclient/command_reply.c.
3172 * Do not print error in silc_file_read if the read file does
3173 not exist. Just silently return NULL. Affected file is
3174 lib/silcutil/silcutil.c.
3176 * Fixed the silc_log_output to not wine about NULL filename
3177 and to not create some bogus " " filename. Affected file is
3178 lib/silcutil/silclog.c.
3180 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3182 * Fixed various printing bugs on the user interface in the
3183 Irssi SILC Client. Minor changes that were forgotten from
3186 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3188 * Fixed the configure.in.pre and the compilation and distribution
3189 environment to support the new autoconf 2.52. That version is
3190 now required to compile the CVS trunk.
3192 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3194 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3195 to generally parse user@fqdn format strings. Affected file
3196 lib/silcutil/silcutil.c.
3198 * Added nickname_format and nickname_force_format fields to the
3199 SilcClientParams structure. The first one defines the format
3200 for the nicknames that the library will enforce if the receives
3201 multiple same nicknames. The second one is boolean value and
3202 can be used to force the library to always enforce the format
3203 to the nicknames regardles whether there are multiple nicknames
3204 or not. This configurable formatting was employed to flexibly
3205 support accessing multiple nicknames from the user interface.
3206 The userinterface can now set the nicknames to what ever format
3207 they prefer. Affected file lib/silcclient/silcapi.h.
3209 Added function silc_client_nickname_format to the file
3210 lib/silcclient/idlist.c. It performs the nickname formatting.
3212 Added new field `hostname´ to the SilcClientEntry context.
3213 It holds the hostname of the client. Affected file is
3214 lib/silcclient/idlist.h.
3216 * Irssi SILC Client sets the nicknames in nick@hostn format.
3217 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3218 irssi/src/silc/core/silc-core.c.
3220 The WHOIS printing now also shows both the real nickname and
3221 the formatted nickname so that user knows how to access the
3222 user if there are multiple same nicknames cached. Affected
3223 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3224 printing formatting too to take the hostname now as a separate
3225 argument. The Affected file is
3226 irssi/src/fe-common/silc/modules-formats.[ch].
3228 * Changed the silc_client_get_clients_local to accept the formatted
3229 nickname as argument. It accepts the real nickname too but the
3230 formatted nickname can be used to find the true entry from
3231 multiple entries. Affected file lib/silcclient/silcapi.h and
3232 lib/silcclient/idlist.c.
3234 * Added nickname_format_parse field to the SilcClientParams.
3235 It is a callback function provided by the application to parse
3236 the nickname out of the formatted nickname string. The library
3237 calls it to get the nickname from the formatted string. Since
3238 the application generally knows better the format of the nickname
3239 string it parses it instead of the library, even though library
3240 encodes the formatted string. If the callback function is not
3241 provided then the library will use the string as is. The
3242 affected file is lib/silcclient/silcapi.h.
3244 * All the nickname strings passed to the client library in
3245 commands are now expected to be formatted nickname strings.
3246 If the command does not support the formatted nickname string
3247 it will assume that the sent string is the actual nickname.
3248 Affected file lib/silcclient/command.c.
3250 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3252 * Added public key authentication support to OPER and SILCOPER
3253 commands in the client library. Affected file is
3254 lib/silcclient/command.c.
3256 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * Changed the get_auth_methdod client operation to be asynchronous.
3259 It can be async if the application resolves the authentication
3260 method from the server during the negotiation. Added new
3261 SilcGetAuthMeth completion callback that the application will
3262 call after resolving the authentication method.
3264 Added function silc_client_request_authentication_method that
3265 the application can use to resolve the authentication method
3266 from the server. Added also SilcConnectionAuthRequest callback
3267 that the library will call after the server has replied. The
3268 application can call this function if it does not know the
3269 current authentication method.
3271 Affected files are lib/silcclient/client.c and
3272 lib/silcclient/silcapi.h.
3274 * The Irssi SILC client now automatically resolves the authentication
3275 method incase any configuration information is not present (and
3276 currently there never is). The affected file is
3277 irssi/src/silc/core/client_ops.c.
3279 * Fixed public key authentication from the client library.
3280 Affected file lib/silcclient/protocol.c. Changed also the
3281 protocol specification about the public key authentication in
3282 the connection authentication protocol. The actual data to be
3283 signed is now computed with a hash function before signing.
3285 * Fixed the public key authentication from the server as well.
3286 Affected file silcd/protocol.c.
3288 * Removed the mlock()'s from the memory allocation routines.
3289 Affected file lib/silcutil/silcmemory.c. The ./configure does
3290 not check anymore for the mlock(). Affected file is
3293 * Fixed USERS command in server to allow the execution of the
3294 command for private and secret channels if the client sending
3295 the command is on the channel. Affected file silcd/command.c.
3297 * Fixed silc_client_get_clients_local to return the clients
3298 count correctly. It could return wrong value. Affected file
3299 lib/silcclient/idlist.c.
3301 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3304 types. The assembler optimizations seemed not to like 64-bit
3305 data types. The assmebler optimizations thus are now enabled
3306 also for BSD systems as opposed to only enable them for Linux.
3308 * Do not check for threads at all on BSD systems. Affected
3309 file configure.in.pre.
3311 * Removed -n and -h options from the Irssi SILC Client since
3312 they are not used in silc.
3314 * Fixed the prime generation to assure that the first digit
3315 of the generated random number is not zero since our conversion
3316 routines does not like number strings that starts with zero
3317 digit. If zero digit is seen the random number is regenerated.
3318 This caused some corrupted RSA keys when the zero first digit
3319 was met. Affected file lib/silcmath/silcprimegen.c.
3321 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3323 * Fixed WIN32 configuration in the ./configure script.
3324 Fixed to include xti.h on environments that has it.
3325 Patches by Carsten Ilchmann and andrew.
3327 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Changed the silc_id_create_client_id to be collision
3330 resistant. It is now assured that there cannot be created
3331 two same client ID's. I suspect that some weird bugs in
3332 the server were actually caused by duplicate Client IDs.
3333 Affected file silcd/serverid.[ch]. A router receiving
3334 new ID now also assures and informs the sending server
3335 if the ID caused collision.
3337 * Changed the silc_id_create_channel_id to also assure that
3338 there are no collisions.
3340 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3342 * Statement about ignoring the Mutual Authentication flag when
3343 performing rekey with PFS was a bit misleading. It is ignored
3344 if it was set in the initial negotiation, it cannot be even
3345 set in the rekey. Fixed in the ke-auth draft. Started the
3346 new versions of the protocol drafts in the doc/.
3348 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3350 * Fixed a bug in silc_client_command_identify_save when saving
3351 new channel information. The channel name was no duplicated
3352 and caused crash on exit. Affected file is
3353 lib/silcclient/command_reply.c.
3355 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3357 * Fixed the getkey command handling in the server. Send just
3358 empty OK reply to the sender if the key could not be fetched
3359 (but everything else was ok, like the key just was not available).
3360 Changed the public key parameter to optional in the protocol
3361 specs so that empty OK reply can be sent. Affected file
3364 Added a message to Irssi SILC client to tell to user if the
3365 server did not return a public key.
3367 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3369 * Fixed a channel key regeneration bug. It registered new
3370 timeout tasks exponentially until all system resources were
3371 used. Affected file silcd/server.c.
3373 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Added the SILC Document generator to the scripts/silcdoc.
3376 It can be used to generate the Toolkit Reference Manual out
3377 of the source tree. Internally it will also use the RoboDoc
3378 generator now imported in util/robodoc.
3380 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Added couple of return's in rekey protocol if error orccurred
3383 during the protocol. The execution must be terminated.
3384 Affected file silcd/protocol.c. Also, terminate the protocol
3385 always with timeout.
3387 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3389 * The client's Client ID was created initally from the wrong
3390 nickname (it could have been in format nick@host) in the
3391 silc_server_new_client. Affected file silcd/packet_receive.c
3393 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Added some SILC_LOG_ERROR's to various error conditions
3396 if client could not be added to ID cache. Affected files
3397 silcd/packet_receive.c and silcd/server.c.
3399 * When client's sock->user_data is freed, NULL also the
3400 client->router and client->connection pointers. Added check
3401 for these pointers being NULL to various places around the
3402 code. Affected file silcd/server.c.
3404 * Added client->data.registered == TRUE checks to various
3405 places around the code to assure that unregistered client's
3406 are not handled when it is not allowed. Affected file
3409 * Added `bool registered' fields to all
3410 silc_idlist_[server|client]_get_* routines to indicate whether
3411 the fetched client needs to be registered or not. Affected
3412 file silcd/idlist.[ch].
3414 * Add your own entry as registered to the ID cache in the
3415 server. Affected file server.c.
3417 * Fixed a bug in silc_server_new_server. The SilcServer was
3418 set as the new server's context instead of SilcServerEntry.
3419 This naturally caused some weird bugs.
3421 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3423 * Do not delete the channel rekey task when adding it
3424 for in silc_server_create_channel_key.
3426 * Changed the silc_server_create_channel_key to return
3427 TRUE or FALSE to indicate the success of the channel key
3430 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Fixed MSVC++ project files and added missing files to
3433 Makefiles under win32/.
3435 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3437 * Do not add TCP_NODELAY flag if the operating system
3438 does not have it defined. Affected files are
3439 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3441 * Fixed buffer overflow from Irssi SILC Client. Affected
3442 file irssi/src/fe-common/core/themes.c.
3444 * Fixed double free in client library in the file
3445 lib/silcclient/client.c when disconnecting from server.
3447 * Applied double free patch from cras to Irssi SILC client.
3448 Affected files irssi/src/core/[modules/expandos].c
3450 * Fixed the disconnection handling to Irssi SILC Client.
3451 The application must call silc_client_close_connection
3452 in ops->connect client operation in case of failure of
3453 the connection. Affected file is
3454 irssi/src/silc/core/client_ops.c.
3456 * Do not set sock->protocol to NULL in the function
3457 silc_client_close_connection after executing the protocol's
3458 final callback since the sock might not be valid anymore.
3459 Affected file lib/silcclient/client.c.
3461 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Do not enable SILC_THREADS if the linking with libpthread
3464 did not happen. Affected file configure.in.pre.
3466 * Added notion to protocol specification that server must
3467 verify the sent authentication payload with CMODE when
3468 setting the channel founder key. Implemented it to the
3469 server. Affected file silcd/command.c.
3471 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Added _EXTRA_DIST SILC distribution variable to the
3474 distributions file. It is used to conditionally add extra
3475 files or directories to the specific distribution. Affected
3476 files ./prepare, Makefile.am.pre and distributions.
3478 Removed the `_' from the start of the distribution names.
3481 * Added README.WIN32 for instructions to compile the Toolkit
3484 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3486 * Fixed a double free in disconnection in the server. Affected
3487 file is silcd/server.c.
3489 * Fixed the lib/silcske/groups.c to work now also with GMP
3490 MP library. The string conversion did not work when using
3491 specific base and the base is indicated in the string as well.
3493 * Created win32/ directory which now includes MSVC++ specific
3494 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3495 It will appear only in the toolkit distribution
3497 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3499 * Changed the key material distribution function in case when
3500 the hash output is too short. The data is now concatenated
3501 a bit differently than it used to. Made the change to the
3502 SKE protocol specification.
3504 * Added better GMP detection to configure.in.pre. A patch
3507 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * Fixed a minor bug in SKE that might cause some problem on
3510 some platforms. Affected file lib/silcske/silcske.c.
3512 * Added the cookie checking for initiator in the SKE. It checks
3513 that the responder returns the sent cookie unmodified. The
3514 affected file is lib/silcske/silcske.c. Added new SKE
3515 error type INVALID_COOKIE that can be sent during the
3516 negotiation. Fixed some memory leaks as well.
3518 * Added the "invalid cookie" error message to Irssi SILC client's
3521 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * Added `task_max' field to the SilcClientParams to indicate
3524 the maximum tasks the scheduler can handle. If set to zero,
3525 default values are used. Affected file lib/silcclient/silcapi.h.
3527 * Fixed memory leaks in silc_client_close_connection. Affected
3528 file lib/silcclient/client.c.
3530 * Added silc_client_del_client_entry to client library to free
3531 all memory of given client entry. Affected file is
3532 lib/silcclient/idlist.[ch].
3534 * Added new functions silc_client_del_channel and
3535 silc_client_del_server to delete channel and server entries.
3536 Affected file lib/silcclient/[silcapi.h/idlist.c].
3538 * Removed silc_client_del_client_by_id from silcapi.h.
3540 * Fixed the INFO command to return the server's own info
3541 correctly when querying by Server ID. Affected file is
3544 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Removed the non-blocking settings in WIN32 code in the
3547 silc_sock_[read/write] and added SleepEx instead. Affected
3548 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3549 of input data is now checked with FIONREAD and ioctlsocket.
3551 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Call silc_schedule_task_del_by_context in the
3554 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3555 Affected file lib/silccore/silcprotocol.c.
3557 * Call silc_protocol_cancel for active protocols in the
3558 silc_server_close_connection if the funtion
3559 silc_server_free_sock_user_data has not been called.
3560 Affected file silcd/server.c.
3562 * Generic tasks cannot be deleted using the del_by_fd
3563 task deleting function since generic tasks does not match
3564 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3566 * Added a notion to SILCOPER help file that the SILCOPER works
3567 only on router server, not on normal server.
3569 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Added for WIN32 support for the new scheduler as well.
3572 Affected file lib/silcutil/win32/silcwin32schedule.c.
3574 * Fixed the SHA1 implementation to work on various platforms.
3576 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3579 API. It is part of the scheduler now. Everything else is
3580 as previously but some functions has changed their names.
3581 Checkout the lib/silcutil/silcschedule.h for the interface.
3582 Updated all applications to use the new interface. Affected
3583 files are lib/silcutil/silcschedule.[ch].
3585 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3587 * Found a bug in the SKE implementation. The HASH value,
3588 specified by the protocol, was not computed correctly. The
3589 public key of the responder was not added to the computation
3590 even though it is mandatory. Affected file lib/silcske/silcske.c.
3591 This unfortunately causes incompatibilities with older
3592 clients and servers.
3594 * Added WIN32 specific network init and uninit functions:
3595 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3596 the Winsock2. Affected file lib/silcutil/silcnet.h and
3597 lib/silcutil/win32/silcwin32net.c.
3599 * Set the socket always to nonblocking mode on WIN32 after
3600 reading data or writing data. Affected file is
3601 lib/silcutil/win32/silcwin32sockconn.c.
3603 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Fixed various compilation problems under WIN32. Affected
3606 files lib/silcutil/win32/silcwin32thread.c and
3607 lib/silcutil/win32/silcwin32schedule.c.
3609 * Removed all _internal.h #includes from public header
3610 files. Internal headers must never be included from
3613 Removed also the lib/silcske/payload_internal.h file.
3615 * All include files that may be needed (public and some others
3616 included by the public headers) by application developers are
3617 now copied to the ./includes directory. It does not copy any
3618 internal headers. Affected file Makefile.defines.pre and all
3619 Makefile.am's under lib/ and subdirs.
3621 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Do not change the ~/.silc directory's permissions automatically.
3624 Affected file irssi/src/silc/core/clientutil.c.
3626 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3628 * Do not cancel the protocol in silc_server_close_connection
3629 it might cause recursion. Now cancelled in the function
3630 silc_server_free_sock_user_data. Affected file silcd/server.c.
3632 * Fixed the silc_server_remove_clients_by_server to regenerate
3633 the channel keys correctly finally. Added also new function
3634 silc_server_remove_clients_channels to actually do it.
3635 Affected file silcd/server.c.
3637 * Fixed the silc_server_new_channel to not crash by giving
3638 wrong router to the new channel. Affected file is
3639 silcd/packet_receive.c.
3641 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3643 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3644 which is given as argument to the silc_client_alloc now.
3645 It can be used to configure the client and set various parameters
3646 that affect the function of the client.
3648 * The USERS command in server did not check whether the channel
3649 is private or secret. Affected file silcd/command.c.
3651 * Added new argument to the USERS command in protocol specification.
3652 The USERS command now can take the channel name as argument
3653 as well. Added support for this in client and server and
3654 updated the protocol specs.
3656 * Completed the GETKEY command in client. It can be now used
3657 to fetch also servers public key not only some clients.
3658 Affected files lib/silcclient/command[_reply].c.
3660 * Added silc_client_get_server to return server entry by the
3661 server name. Affected files lib/silcclient/silcapi.h and
3664 * Redefined the IDENTIFY command in protocol specification to be
3665 more generic. It now can be used to query information about
3666 any entity in the SILC Network, including clients, servers and
3667 channels. The query may be based either the entity's name
3668 or the ID. Added support for this in both client and server.
3670 Affected files silcd/command.c and lib/silcclient/command.c
3671 and command_reply.c.
3673 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3674 the _from_client and _from_server functions. Affected file
3677 * Added silc_client_get_channel_by_id_resolve to the file
3678 lib/silcclient/silcapi.h to resolve channel information by
3679 its ID. Added also silc_client_get_channel_by_id that
3680 does not resolve it from the server.
3682 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3684 * Added SilcServerEntry context into the client library
3685 to represent one server. The INFO command now allocates
3686 these to save the resolved server info. For now on the
3687 client library will also keep information about servers,
3688 connected and resolved with INFO.
3690 The INFO command now allocates the SilcServerEntry context
3691 and saves the server info there. The COMMAND_REPLY in
3692 the INFO now returns the parameters to application in
3693 same order as defined in the protocol specification.
3695 The entries are cached in the client->server_cache.
3697 * The INFO command is now issued after received the Client ID
3698 from the server. Affected file lib/silcclient/client.c.
3700 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3701 to the application as the mode changer might be server.
3702 It is guaranteed that NULL is not returned anymore to the
3703 application. Affected file lib/silcclient/client_notify.c.
3705 The ID Type is now also passed to the application so that
3706 it can check whether the returned entry is SilcClientEntry
3709 Added new function silc_client_get_server_by_id to return
3710 the server entry by ID. Affected files are the
3711 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3713 * Do not create the channel in the Irssi SILC Client when issuing
3714 the JOIN command but when received the sucessful JOIN command
3715 reply. Otherwise the channel might get created even though we
3716 could not join it. The Affected file is
3717 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3719 * Fixed a channel joining bug in router. The router must also
3720 check the channel modes, invite and ban lists etc. when serving
3721 the JOIN command sent by normal server. Affected file is
3722 silcd/command.c. The router now resolves the client's
3723 information from the server who sent the JOIN command if it
3724 does not know it, and processes the JOIN command only after
3727 * Changed the SilcCommandCb to take new argument; void *context2.
3728 Affected file lib/silccore/silccommand.h
3730 The second argument in the command callbacks in the server now
3731 includes the SilcServerCommandReplyContext if the command was
3732 called as pending command callback from the command reply.
3733 Otherwise it is NULL. When called as pending the status of the
3734 command reply will be checked and if it was erronous the
3735 error will be sent to the original sender of the command.
3736 This way the client always receives the error messages even
3737 though the server was actually the one who received the error
3738 when it resent the command to router, for example. Affected
3739 files silcd/command[_reply].[ch].
3741 * Fixed sending WHOWAS command's error message to client if
3742 the requested client could not be found. It was missing.
3745 * Changed the CMODE and CUMODE commands reply arguments in the
3746 protocol specification. The Channel ID is now sent in both
3747 of the commands to identify the channel. Implemented this
3748 new feature to the client and server. Affected files
3749 lib/silcclient/command_reply.c and silcd/command.c.
3751 * Made better checks for invite and ban lists in the JOIN
3752 command in server. Affected file silcd/command.c.
3754 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3756 * The server now performs the incoming host IP/DNS lookup
3757 using the silc_socket_host_lookup and thus does not block
3758 the server anymore. Affected file silcd/server.c.
3760 * Completed the multi-thread support for SILC Scheduler in
3761 the lib/silcutil/silcschedule.c.
3763 * Fixed the configure.in.pre to detect the pthread correctly
3766 * Fixed a deadlock in silc_task_queue_wakeup in the file
3767 lib/silcutil/silctask.c.
3769 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Added new function silc_schedule_wakeup that is used in
3772 multi-threaded environment to wakeup the main thread's
3773 schduler. It needs to be used when a thread adds a new task
3774 or removes a task from task queues. After waking up, the
3775 scheduler will detect the task queue changes. If threads
3776 support is not compiled in this function has no effect.
3777 Implemented the wakeup mechanism to both Unix and WIN32
3778 systems. Affected files are lib/silcutil/silcschedule.[ch],
3779 lib/silcutil/unix/silcunixschedule.c and the
3780 lib/silcutil/win32/silcwin32schedule.c.
3782 * Added new function silc_task_queue_wakeup to wakeup the
3783 scheduler by the specified task queue. Affected file
3784 lib/silcutil/silctask.[ch].
3786 * The silc_socket_host_lookup_start now wakes up the scheduler
3787 after adding the timeout task. Affected file is
3788 lib/silcutil/silcsockconn.c.
3790 * The silc_socket_host_lookup is synchronous now if the threads
3791 support is not compiled in. However, the callback is still
3792 called asyncronously through the scheduler, anyway. Affected
3793 file lib/silcutil/silcsockconn.c.
3795 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3797 * Added new function silc_socket_host_lookup to perform
3798 asynchronous IP and FQDN lookups for the socket connection.
3799 Affected files lib/silcutil/silcsockconn.[ch].
3801 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3803 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3804 that may or may not compile the mutex support in.
3806 Changed the silc_mutex_alloc interface. It allocates the
3807 mutex now to the sent pointer and returns TRUE or FALSE.
3809 Affected file lib/silcutil/silcmutex.h.
3811 * Wrote the SILC Task Queue interface to support multi-threads.
3812 Affected file lib/silcutil/silctask.[ch].
3814 * Wrote the SILC Scheduler to support multi-threads. Affected
3815 file lib/silcutil/silcschedule.c.
3817 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3819 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3820 in lib/silcutil/win32/.
3822 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3824 * Defined SILC Mutex API and SILC Thread API and implemented
3825 them for Unix. Affected files are
3826 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3827 lib/silcutil/unix/silcunixmutex.c and
3828 lib/silcutil/unix/silcunixthread.c.
3830 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3832 * Fixed the silc_server_remove_clients_by_server's channel
3833 key re-generation. The hash table handling was incorrect
3834 and would not work with many channels. Affected file is
3837 * Fixed some memory leaks around the server code.
3839 * Rewrote the silc_server_get_users_on_channel to support IPv6
3840 based Client ID's. Affected file silcd/server.c.
3842 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3843 specification. However, a separate document must be written
3844 to define the detailed signing procedure and the payload
3845 associated with the flag. Defined the flag to the
3846 lib/silccore/silcchannel.h as well.
3848 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3850 * Changed the dynamic tables to static size tables in the
3851 lib/silccrypt/silchmac.c.
3853 * Removed GCC dependencies from the code. A patch by cras.
3855 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3857 * Do not show the error "Error receiving packet bla bla"
3858 in server if it really was not an error (-2 means that reading
3859 is pending). Affected file silcd/server.c.
3861 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Fixed a possible crash in silc_server_remove_clients_by_server
3864 in silcd/server.c. Fixed there also some memory leaks.
3866 * Fixed the silc_idlist_replace_client_id. It could replace
3867 wrong key in the hash table. Affected file silcd/idlist.c.
3869 * Do not check whether there are global users on the channel
3870 if the channel->global_users is FALSE. Affected functions
3871 silc_server_remove_from_one_channel and
3872 silc_server_remove_from_channels in silcd/server.c. Also,
3873 do not check if the removed client is local as we can be
3874 sure that global client was not removed from the channel
3875 and checking for global users is not needed.
3877 * The silc_server_remove_clients_by_server now re-generates
3878 the channel keys correctly for those channels that had
3879 clients removed from them. Affected file silcd/server.c.
3881 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3883 * Found the reason of random crashes in the server. We weren't
3884 ignoring the SIGPIPE signal (which can be sent in write())
3885 and it crashed the server. Affected file silcd/silcd.c.
3887 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3889 * Assure that sock->user_data is not NULL in the function
3890 silc_server_packet_send in silcd/packet_send.c.
3892 * Disconnect the remote connection if it could not be added
3893 to any ID lists in the server. The affected file is
3896 * Check in silc_server_packet_send[_real/dest] that the
3897 socket is not disconnecting and ignore the data if it is.
3898 Affected file silcd/packet_send.c.
3900 * Define inline to __inline on native WIN32 compilation.
3901 Affected file includes/silcwin32.h.
3903 * Added some explicit type casts for inline code since MSVC
3904 require them. Affected files lib/silcutil/silcbuffer.h,
3905 lib/trq/silcdlist.h and lib/trq/silclist.h.
3907 * Print warning in log files from now on if the packet
3908 decryption fails. Affected file silcd/server.c.
3910 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3912 * Changed the `say' client operation's interface to accept
3913 new `type' argument to indicate the type of the message sent
3914 by the library. The application may filter the library's
3915 messages according the type. The affected file is the
3916 lib/silcclient/silcapi.h.
3918 * Added two new functions to lib/silcclient/silcapi.h:
3919 silc_client_del_client and silc_client_del_client_by_id.
3920 Affected file lib/silcclient/idlist.c.
3922 * Moved the clientincludes.h from includes/ to silc/ and
3923 serverincludes.h from includes/ to silcd/.
3925 * The modes for the CMODE and CUMODE are now passed as
3926 uint32 for application with COMMAND_REPLY. The affected
3927 file is lib/silcclient/command_reply.c.
3929 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3931 * /WHOIS without arguments shows client's own information.
3932 Affected file lib/silcclient/command.c.
3934 * Changed PING to not accept any arguments. The specs
3935 says that client can ping only the connected server so
3936 requiring an argument is not needed. Affected file is
3937 lib/silcclient/command.c.
3939 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3941 * Fixed a fatal bug in private message sending and reception
3942 encryption and decryption when using private message keys.
3943 The implementation was incorrect and did not follow the
3944 specification. It causd that some of the message were
3945 lost since it did not use the sending and receiving keys
3946 as the protocol suggests. This has been fixed and will cause
3947 incompatibilities with older clients when sending private
3948 message encrypted with private message keys. Affected files
3949 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3950 and various other in Irssi SILC Client.
3952 Added `responder' boolean argument to the functions
3953 silc_client_add_private_message_key[_ske] to indicate when
3954 the key is added as responder or initiator of the key
3957 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3959 * Removed the silc_ske_check_version function and created
3960 a SilcSKECheckVersion callback. Added also a function
3961 silc_ske_set_callbacks that is now used to set all SKE
3962 callbacks. The callback functions are not given to
3963 the SKE functions anymore, but this function is used to
3966 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3968 * Added `silc_version' argument to the silc_client_alloc
3969 to define the version of the application for the library.
3970 The library will use the version string to compare it
3971 against the remote host's (usually a server) version
3972 string. Affected file lib/silcclient/silcapi.h
3974 * Added the KE protocol context to Key Agreement context
3975 in client library so that we can abort the SKE if it
3976 is in process when we get timeout. Affected file is
3977 lib/silcclient/client_keyagr.c.
3979 * Do not resolve the client ID forever if it returns in the
3980 first time that such client does not exist. This was done
3981 for example with private message. Affected file is
3982 lib/silcclient/client_prvmsg.c.
3984 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Do not add regex.h for WIN32. The affected file
3987 includes/silcincludes.h.
3989 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3990 not work yet 100%. It generates the DLL's automatically
3991 when compiling with --with-win32 under cygwin.
3993 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3995 * lib/contrib/regex.c is not compiled on WIN32.
3997 * Added silc_net_get_socket_opt function to the
3998 lib/silcutil/silcnet.h.
4000 * Added includes/silcwin32.h for WIN32 specific includes
4003 * Do not use ptime structure or any of the posix process
4004 functions on WIN32 in lib/silccrypt/silrng.c.
4006 * Added silc_gettimeofday to provide generic function
4007 for struct timeval on all platforms. Added the function
4008 to lib/silcutil/silcutil.h.
4010 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4013 library as they clearly belong there. As a plus side we
4014 can make the actual socket connection routines platform
4017 Added also new generic function silc_socket_read and
4018 silc_socket_write (that used to be silc_packet_[read/write].
4019 The implementation of these are platform specific.
4021 * Added WIN32 specific routines of silc_socket_[read/write]
4022 to lib/silcutil/win32/silcwin32sockconn.c.
4024 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4026 * Added preliminary support for native WIN32 compilation under
4027 cygwin (using the -mno-cygwin option for GCC) to the
4028 ./configure.in.pre. The --with-win32 now prepares the
4029 compilation for native WIN32.
4031 * Rewrote the SILC Scheduler interface in the file
4032 lib/silcutil/silcschedule.h. The scheduler is now context
4033 based and does not have anymore any global static scheduler.
4034 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4035 and created lib/silcutil/win32 directory for WIN32 based
4038 * Added Unix specific network routines to the
4039 lib/silcutil/unix/silcunixnet.c and the old
4040 lib/silcutil/silcnet.c includes now only generic routines.
4042 Added WIN32 specific network routines to the
4043 lib/silcutil/win32/silcwin32net.c.
4045 * Added Unix specific utility functions from the
4046 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4048 * Added WIN32 SILC Scheduler to the file
4049 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4052 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Do not handle JOIN notify in the server if the target client
4055 is not registered (idata->registered == FALSE). The affected
4056 file is silcd/packet_receive.c.
4058 * Update the nickrec->founder in event_cumode in the Irssi SILC
4059 client. Affected file irssi/src/silc/core/silc-channels.c.
4061 * Fixed the CUMODE_CHANGE notify handling in the server when
4062 server and router are announcing their clients on channels.
4063 Now the mode changes are saved and notified correctly. The
4064 affected file is /silcd/packet_receive.c.
4066 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4067 They really did not replace the cache entry in the ID Cache.
4068 Now they do that. Affected file silcd/idlist.c.
4070 * Fixed the KICK notify handling in the Irssi SILC client to
4071 update the channel records so that the kicked client does not
4072 appear to be on the channel. The affected file is
4073 irssi/src/silc/core/silc-channels.c.
4075 * Always update the conn->current_channel when executing command
4076 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4078 * Fixed the KILL notify handling in Irssi SILC client to remove
4079 the killed client on all channels.
4081 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4083 * Fixed the silc_parse_command_line to remove extra spaces
4084 from the start and end of the arguments. Affected file is
4085 lib/silcutil/silcutil.c.
4087 * Cancel and free any active protocol in the function
4088 silc_server_close_connection. Affected file silcd/server.c.
4090 * Cancel and free any active protocol in the function
4091 silc_client_close_connction. Affected file is
4092 lib/silcclient/client.c.
4094 * Do not execute the KILL command for clients that are in
4095 history (ie. they are not in the network). Affected file is
4098 * Fixed KILL notify handling, client does not crash anymore.
4099 Affected file irssi/src/silc/core/silc-channels.c.
4101 * Reduced the default packet buffer size from 2048 to 1024 in
4102 lib/silccore/silcpacket.c.
4104 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4105 counter to the SKE context that is incresed when the SKE library
4106 performs async operation outside the library. If the outside
4107 process frees the SKE context and FREED status will be set
4108 and the library will detect after the sync operation that the
4109 libary is freed. The affected files are
4110 lib/silcske/silcske[_status].[ch].
4112 * Resolve the client entry information in the function
4113 silc_client_channel_message to assure that NULL pointer is not
4114 passed as client entry to the application. */
4116 * Fixed the task timeout calculation to assure that there is
4117 never negative timeouts. The affected file is
4118 lib/silcutil/silcschedule.c.
4120 * Fixed the channel user mode notification sending in server.
4121 It was sent point-to-point to the router (or to server by router)
4122 but it needs to be destined to a channel. The routines now
4123 supports sending the channel user mode notifys to the channels
4124 when announcing clients and channels. Affected files are
4125 silcd/server.c and silcd/packet_receive.c.
4127 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4128 It did not actually replace the old channel entry in the cache.
4129 Affected file lib/silcclient/client_notify.c.
4131 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Fixed a possible crash in silc_packet_send_prepare. It now
4134 assures always that there is enough space in the buffer and
4135 at the tail area of the buffer (for MAC).
4137 Fixed the inbound buffer reallocation in silc_packet_read.
4138 It was old code and did not handle the reallocation correctly.
4141 The affected file is lib/silccore/silcpacket.c.
4143 * Fixed buffer overflow in silc_parse_nickname in the file
4144 lib/silcutil/silcutil.c.
4146 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * make install generates new server keys only if there is not
4151 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4154 Added check that if the NOREPLY is set then we will not send
4155 the away message. This avoids infinite loop of away messages
4156 if both clients are away. The affected file is
4157 lib/silcclient/client_prvmsg.c.
4159 * Fixed client crash if /NICK was given without arguments.
4160 Affected file lib/silcclient/command.c.
4162 * Server does not send the invite list in INVITE command back
4163 to the client if the list was not altered. Added this notion
4164 to the protocol spec as well. Affected file silcd/command.c.
4166 Fixed possible crash in INVITE command by checking the
4167 value of silc_server_get_client_route command.
4169 * Fixed the INVITE notify type handling. The arguments are now
4170 taken in correct order and client does not crash. The affected
4171 file is irssi/src/silc/core/silc-channels.c.
4173 Removed the "Inviting xxx to channel" message from the
4174 client library away and let the application handle it.
4175 Affected file lib/silcclient/command.c. Added that message
4176 to Irssi SILC client's message formats.
4178 * Fixed CMODE command crash in client. It now checks the
4179 amount of arguments correctly and does not crash. The affected
4180 file is lib/silcclient/command.c.
4182 * Do not create new channel automatically in silc_channels_join
4183 but check whether the channel by that name already exists.
4184 Affected file irssi/silc/core/silc-channels.c.
4186 * Do not send the SERVER_SIGNOFF to router if the disconnected
4187 entity was the router. Affected file silcd/server.c.
4189 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4190 SILC client as it was missing from there.
4192 Added the handling of the KICK notify to the Irssi SILC client
4193 as it was missing. Added "you have been kicked" message to
4194 Irssi SILC client's message modules formats.
4196 Added the handing of the KILL notify to the Irssi SILC client
4197 as it was missing. Added the kill message module formats
4200 The affected file is irssi/src/silc/core/silc-channels.c.
4202 * The router did not save the channel mode the server announced.
4203 Affected file silcd/packet_receive.c.
4205 * Fixed a possible crash in INFO command in server. If the
4206 server did not provide the server info it crashed. Affected
4207 file silcd/command.c.
4209 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Fixed the GETKEY command in the server to check also the
4212 global list. Otherwise the GETKEY would not work correctly
4213 in normal SILC server. Affected file silcd/command.c.
4215 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Fixed GETKEY crash, it crashed if the command did not succseed.
4219 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4221 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4222 is now real and not just an macro interface to GMP.
4224 Removed the entire GMP from the source tree and imported new
4225 NSS MPI library instead. Reason for removing GMP is that it is
4226 extremely large and compiles extremely slow. The NSS MPI
4227 is only a few files and compiles in less than 10 seconds.
4228 The speed is also about the same as GMP. The MPI is imported
4229 to lib/silcmath/mpi.
4231 If the system has GMP installed we will still use the GMP.
4232 If it is not then the NSS MPI will be compiled.
4234 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Merged a long nickname (127 characters long) crash bugfix from
4237 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4239 * Merged a freed memory reference bugfix from Irssi CVS tree.
4240 Affected file irssi/src/core/commands.c.
4242 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added the server's public key sving and verification to the
4245 server when performing the SKE. This was missing and the
4246 remote server's (or router's) public key was accepted without
4247 checking whether we have it previously or trust it at all.
4248 Affected file silcd/protocol.c.
4250 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Check in the silc_server_timeout_remote if protocol is active
4253 and make sure that the protocol's final callback is called so
4254 that all memory if freed. Affected file silcd/server.c.
4256 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * silc_server_whois_send_reply crashed the server if the nickname
4259 was 127 characters long. Affected file silcd/command.c.
4261 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added sanity check to the silc_server_new_client. If the hostname
4264 is provided inside username then check that the provided hostname
4265 really is the same as the resolved one. If the hostname was not
4266 resolved then check it from the public key. Affected file is
4267 silcd/packet_receive.c.
4269 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4270 if the server disconnected us and the connection is not valid
4271 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4273 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4274 the library to the lib/silcutil/silcutil.[ch].
4276 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Close log file after open. Affected file
4279 lib/silcutil/silclog.c.
4281 * Check whether sock == NULL in silc_client_send_packet and return
4282 if it is. Affected file lib/silcclient/silcclient.c.
4284 * Check rec->entry == NULL in the Irssi SILC Client before
4285 sending the channel message. Affecte file is
4286 irssi/src/silc/core/silc-servers.c.
4288 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4290 * Merged a splitted window bugfix from Irssi CVS tree. The
4291 affected file is irssi/src/fe-text/textbuffer-view.c.
4293 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4294 It did not print nickname.
4296 * Improved the distributions system a bit.
4298 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4300 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4301 irssi/src/fe-text/gui-window.c.
4303 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4304 to in-active server. The affected file is
4305 irssi/src/silc/core/client_ops.c.
4307 * Resolve the client in USERS command reply if the entry does
4308 not have username resolved. The affected file is
4309 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4310 command to WHOIS command to really resolve stuff. The USERS
4311 is not used any more in any critical section so WHOIS can
4312 be used even though it might be slower than IDENTIFY.
4314 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4317 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Changed the protocol API a bit more consistent in the
4320 lib/silccore/silcprotocol.[ch].
4322 * Changed the following headers to ROBODoc format:
4324 lib/silccore/silcpayload.h
4325 lib/silccore/silcprotocol.h
4326 lib/silccore/silcsockconn.h
4328 All core library headers are now formatted.
4330 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4332 * Fixed a bug in Irssi SILC client; do not show that you are
4333 server/router operator if you really are not. Affected file is
4334 irssi/src/silc/core/client_ops.c.
4336 * Renamed silc_command_free_payload to silc_command_payload_free.
4337 Affected file lib/silccore/silccommand.h
4339 * Added silcmath.h to include the prototoypes of various routines
4340 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4343 * Changed the following headers to ROBODoc format:
4345 lib/silccore/silcchannel.h
4346 lib/silccore/silccommand.h
4347 lib/silccore/silcid.h
4348 lib/silccore/silcidcache.h
4349 lib/silccore/silcmode.h
4350 lib/silccore/silcnotify.h
4351 lib/silccore/silcpacket.h
4352 lib/silcmath/silcmath.h
4354 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4356 * Added checking to the server code not to start the server if
4357 ciphers and stuff are not configured properly. Affected files
4358 silcd/serverconfig.[h] and silcd/server.c.
4360 * Changed the layout of the header files of the public interfaces
4361 in the SILC libraries. The new layout supports ROBODoc
4362 documentation tool (and some others) so that it is easy to create
4363 a library reference manual. All the other headers and source
4364 code must still follow the CodingStyle document. Also source
4365 code must not include these ROBODoc stuffs, only the headers.
4366 Furthermore, all public interface headers must now be named
4367 by using `silc' prefix, example: silcapi.h, silccipher.h.
4368 Some files were renamed due to this. All the other headers
4369 must not be used as public interfaces. I will update the
4370 CodingStyle document later. Changed following headers, so far:
4372 lib/silcclient/silcapi.h
4373 lib/silccore/silcauth.h
4374 lib/silccore/silcprivate.h
4375 lib/silccrypt/silcdh.h
4377 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Removed silc_client_packet_send_flush from the client library
4382 as it is not needed. Affected file lib/silcclient/client.[ch].
4384 * Added printing of message of unresolved authentication method
4385 to the Irssi SILC client. Added it to the module formats.
4386 Removed the same message from the client library.
4388 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4390 * Added new distribution feature, DISTLABEL. Every distribution
4391 can define own preprocessor label that can be used in the
4392 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4393 file distributions, acconfig.h.pre and prepare.
4395 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added Makefile.defines_int to include the actual definitions
4398 for Makefile.defines.in. Tested the new distribution system,
4399 created distributions and tested installation.
4401 * Added AWAY message printing to the Irssi SILC client. Added
4402 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4404 * Added SCONNECT command to call the SILC's CONNECT command.
4405 Cannot use CONNECT directly since Irssi uses that internally.
4406 Affected file irssi/src/silc/core/silc-servers.c.
4408 Added ACTION local command. It is same as ME command but takes
4409 the channel as mandatory argument.
4411 Rewrote some of the Irssi's help files to suite for SILC
4414 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Added Makefile.defines[.in] that should for now on be included
4417 in all Makefile.am file in the source tree. That file includes
4418 all common compilation definitions for SILC source tree.
4420 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * Minor changes to the ./prepare script to change the package
4423 name according the distribution name to the configure.in.
4425 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Created new distribution system. Added file `distributions'
4428 that defines all the distributions that can be created out of
4429 the SILC source tree. The ./prepare script now reads that
4430 file to determine how to prepare the distributions. The
4431 first argument to the ./prepare is the name of the distribution
4432 and second is the version of the distribution. If given
4433 without arguments it creates the default (toolkit) distribution
4434 with the default version (defined in ./prepare).
4436 All Makefile.am files that are subject to the distributions
4437 are now named as Makefile.am.pre. These are ./Makefile.am
4438 and lib/Makefile.am. Others may be changed later.
4440 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4442 * Added invite list, ban list, some key management and connection
4443 error message printing to module formats in the Irssi SILC client.
4445 * Added new silc_client_set_away_message to set the away message
4446 that is back to the person who sent private message. The
4447 affected file lib/silcclient/silcapi.h and the
4448 lib/silcclient/client_prvmsg.c.
4450 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Fixed the private message sending in the Irssi SILC client,
4453 added local command KEY to the Irssi SILC client.
4455 Added key management and key agreement message formats to the
4456 irssi/src/fe-common/silc/module-formats.[ch].
4458 Added USERS (alias WHO) printing, server/router operator
4459 indication and LIST command printing to the module formats.
4461 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Fixed channel joining notify handling, cumode notify handling
4464 from Irssi SILC client.
4466 * Added SILC specific module-formats to the Irssi SILC client so
4467 that SILC specific message hilighting, colors etc is possible.
4468 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4470 Added channel mode, channel user mode, actions, notices,
4471 whois and whowas printing to the the module-formats.c.
4473 * Fixed a bug in channel deletion in the server. The channel
4474 is not left to the cache even if the channel founder auth mode
4475 is set when there are no users anymore on the channel. Affected
4476 file silcd/server.c.
4478 * The silc_net_localhost now resolves the entire hostname including
4479 the domain name. Affected file lib/silcutil/silcnet.c.
4481 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Changed the ask_passphrase client operation to be ascynchronous.
4484 It has now a completion callback and a context that the
4485 application must call after it has got the passphrase from
4486 the user. Affected files lib/silcclient/silcapi.h,
4487 lib/silcclient/protocol.c, lib/silcclient/command.c and
4490 Added SilcAskPassphrase callback that the application calls
4491 to deliver the passphrase to the library.
4493 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4494 The public key verification and especially a certificate
4495 verification is asynchronous procedure.
4497 Added new SILC_SKE_STATUS_PENDING status to indicate the
4498 request is pending and a callback will be called to finalize
4501 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4502 indicate that remote end did not send its public key (or
4503 certificate), even though we require it. Added check for this
4504 condition in the SKE. This was a security bug, now fixed.
4506 Defined new SilcSKEVerifyCbCompletion callback that is called
4507 when the verification process is completed.
4509 The affected files lib/silcske/silcske_status.h and
4510 lib/silcske/silcske.[ch].
4512 * Changed the verify_public_key client operation to be async
4513 as well. Defined SilcVerifyPublicKey callback that is used to
4514 indicate the success of the public key verification process.
4516 Changed the server and client to use the new async client
4519 * Changed the Irssi SILC client's internal scheduler to be called
4520 twice as many times as it used to be. As a result the client
4521 should be a bit faster now. Affected file is
4522 irssi/src/silc/core/silc-core.c.
4524 * Added support to Irssi SILC client of asynchronous public key
4525 verification and passphrase inquiry. Affected file is
4526 irssi/src/silc/core/silc-core.c.
4528 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Do not say "You have left channel %s" in client library.
4531 Moved it to the application. Affected files are
4532 lib/silcclient/command.c and silc/client_ops.c.
4534 * Fixed silc_client_get_clients. Command context was not
4535 duplicated and was freed memory in the callback. Affected
4536 file lib/silcclient/idlist.c.
4538 * Do not say "you are now talking..." on JOIN command in the
4539 client library. The appliation must handle it.
4541 * Do not say ".. changed topic to" in command reply in the
4542 client libary. The application must handle it.
4544 * Fixed TOPIC command sending in the client library.
4546 * Fixed a memory leak in silc_client_command_free in the file
4547 lib/silcclient/command.c.
4549 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Imported a modified version of Irssi client to the source tree.
4552 The Irssi will be used to create a new client called
4553 Irssi SILC. Imported to irssi/.
4555 Added silc_core_init_finish function to the Irssi. Affected
4556 file irssi/configure.in.
4558 A lot changes in the Makefile.ams around the irssi tree.
4560 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4562 * Do not rehash if the new size is same as the old size of the
4563 hash table, in the silc_hash_table_rehash*. The affected file
4564 lib/silcutil/silchashtable.c.
4566 * Replaced hash_table_del_by_context calls from the server
4567 (when channel->user_list and client->channels) to the
4568 hash_table_del as it is sufficient and faster.
4570 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Added silc_hash_table_list, silc_hash_table_get and the
4573 SilcHashTableList structure to provide an alternative way to
4574 traverse the hash table. The affected files are
4575 lib/silcutil/silchashtable.[ch].
4577 * Changed the server's idlist routines to use the hash table
4578 routines to optimize the code.
4580 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Replaced the client entry's `channel' list and channel entry's
4583 `user_list' list to hash tables for optimized lookup. Changed
4584 the code to use the hash table interface around the code.
4585 Affected file lib/silcd/idlist.[ch].
4587 * Added `auto_rehash' boolean argument to the function
4588 silc_hash_table_alloc to indicate whether the hash table should
4589 auto-rehash when it thinks is appropriate time. It will
4590 increase the hash table size if the there is twice as much
4591 entries in the table than the size of the table, and will
4592 decrease the size if there are twice as less entries than
4593 the size of the table.
4595 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4599 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * silc_idcache_purge_by_context deletes the entry now by context
4602 as it is supposed to do. Affected file lib/silccore/idcache.c.
4604 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4605 client is not anymore valid (WHOWAS givens the info) and not
4606 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4608 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Removed the `data' and `data_len' arguments from the ID Cache
4611 interfaces and added `name' argument. ID Cache does not handle
4612 anymore the binary data only a names associated with given ID.
4614 * When hashing a Client ID with silc_hash_id the entire ID is
4615 not hashed anymore, instead only the hash of the Client ID is
4616 hashed. This way we can access the Client ID from the cache
4617 with Client ID but with the hash of the ID (which is a hash of
4618 the nickname) as well without any difference in performance.
4620 Added also silc_idcache_find_by_id_one_ext to do one on one
4621 searching when we have the actual ID. Added also function
4622 silc_hash_client_id_compare. The affected files are
4623 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4625 * When hashing the name associated with a ID it is always done
4626 in lowercase. This way we can access the cache without worrying
4627 about case-sensitivity, even though, for example nicknames are
4630 * Fixed a bug in server with channel message sending. It put
4631 wrong ID type as destination ID. The affected file
4632 silcd/packet_send.c.
4634 * silc_idcache_del_by_context now deletes from all hash tables
4635 by context. Affected file lib/silccore/idcache.c.
4637 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Changed the client library to use the new ID Cache interface.
4640 Changes around the source tree.
4642 * Added silc_hash_table_rehash_ext to rehash with specific
4643 hash function. Affected file lib/silcutil/silchashtable.[ch].
4645 * Added silc_hash_string_compare to compare two strings in the
4646 hash table. Affected file lib/silcutil/silcutil.[ch].
4648 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Added new function silc_idcache_del_by_context into the
4651 lib/silccore/idcache.[ch].
4653 * Changed the server's ID list routines to use the new ID Cache
4654 interface. Changes around the source tree.
4656 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Added silc_hash_table_del[_by_context]_ext functions in to the
4659 lib/silcutil/silchashtable.[ch].
4661 Removed silc_hash_table_find_all* routines and added new
4662 silc_hash_table_find_foreach to replace them.
4664 Added silc_hash_table_replace_ext function as extended
4665 replacing function. Separated the simple hash table interface
4666 from the extended hash table interface in the file
4667 lib/silcutil/silchashtable.h.
4669 * Fixed minor bugs and changed it to use some of the new
4670 hash table functions in lib/silccore/idcache.c
4672 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4674 * Added new function silc_hash_table_find_all to return all keys
4675 in the hash table by the specified key. As the hash table is
4676 collision resistant it also makes it possible to have several
4677 duplicate keys in the hash table. This function may be used to
4678 find all of the keys from the hash.
4680 Added user_context arguments to the SilcHashFunction,
4681 SilcHashCompare and SilcHashDestructor to deliver user specified
4684 Added new fuctions silc_hash_table_find[_all]_ext to do
4685 extended lookup with specified hash and compare functions and
4686 specified user contexts.
4688 Added new function silc_hash_table_add_ext to add the key
4689 with specified hash function and user context.
4691 Added new function silc_hash_table_foreach to traverse all
4692 entrys in the hash table. Added SilcHashForeach callback
4695 Added new function silc_hash_table_del_by_context to delete
4696 the entry only if the context associated with the key matches.
4698 Affected files are lib/silcutil/silchashtable.[ch].
4700 * Removed silc_hash_[server/client/channel]_id and added just
4701 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4702 silc_hash_id_compare to compare two ID's using as the hash table
4703 comparison function. Added also silc_hash_data to hash
4704 binary data and silc_hash_data_compare to compare it.
4706 * Removed silc_idlist_find_client_by_hash as it is not needed
4707 anymore. Affected file silcd/idlist.[ch].
4709 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4710 to use internally the SilcHashTable. The new ID Cache is a lot
4711 faster than the old one. Some of the ID Cache interface was also
4712 rewritten and obsolete and stupid functions were removed.
4714 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4716 * Added entry_count field to the SilcHashTable to keep the number
4717 of the entries in the table. Implemented the function
4718 silc_hash_table_rehash. Added new function
4719 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4721 Fixed a minor bug in silc_hash_table_free.
4723 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4724 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4725 into the lib/silcutil/silcutil.[ch].
4727 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4729 * Implemented a collision resistant hash table into the
4730 lib/silcutil/silchashtable[ch]. See the header and the source
4731 for the SilcHashTable API.
4733 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4735 * Merged dotconf version 1.0.2 into lib/dotconf.
4737 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4739 * Do not compile anything in lib/silcsim/* if the SIM support
4740 is not enabled. The tree should now compile without problems
4743 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4745 * Compiled the SILC under cygwin. Compiled and tested briefly
4746 without problems. More tests needed. The SIMs didn't compile
4749 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4751 * Fixed possible crash in silc_get_username in the
4752 lib/silcutil/silcutil.c.
4754 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Fixed a va_arg in silc/client_ops.c.
4758 * Oops, RC5 routines were named AES and caused some problems
4759 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4761 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Added new SilcIDIP structure into the lib/silccore/id.h and
4764 replaced the old `ip' fields from all SILC ID's to that type.
4765 This is a step towards IPv6 support.
4767 The silc_id_get_len takes now the ID as an extra argument.
4768 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4769 both IPv4 and IPv6 based ID's.
4771 The affected files are lib/silccore/id.[ch] and other files
4772 around the tree using these routines.
4774 * Removed the ID length arguments in server from various
4775 silc_server_send_notify_* routines -> they are not needed
4778 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4780 * Fixed memory leak in silc_encode_pem_file in the file
4781 lib/silcutil/silcutil.c.
4783 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4785 * Check minor version as well in the SKE. Affected files are
4786 silcd/protocol.c and lib/silcclient/protocol.c.
4788 * Added --identifier option to the server so that an identifier
4789 can be when creating the public key for the server. Affected
4790 file is silcd/silcd.c.
4792 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4793 lib/silccrypt/silcpkcs.c.
4795 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Register default ciphers and stuff when using -C option with
4798 the server. Affected file sildc/silcd.c.
4800 * Put back the servers public key filename format, it is better
4801 than the new one. For now, the client keys are saved with the
4802 new filename format. The affected file silc/client_ops.c.
4804 * Implemented the Cipher API for the rest of the ciphers that
4805 did not implement it or implemented it the wrong way.
4807 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Register default ciphers and stuff when using the -S option
4810 in the client. Affected file silc/silc.c. Same also when
4811 creating new key pair with -C option.
4813 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4815 * Fixed the silc_verify_public_key client operation function to
4816 save the public keys differently. The fingerprint is now
4817 used as filename and not the hostname. This way also the
4818 client keys are saved uniquely and not with hostnames. The
4819 affected file is silc/client_ops.c.
4821 * Trimmed the silc_hash_fingerprint function to remove extra
4822 whitespaces from the end of the fingerprint. The affected
4823 file is lib/silccrypt/silchash.c.
4827 * Added silc_cipher_register_default function to register all
4828 default ciphers. It can be used when configuration files
4829 does not exist and the application does not want any specific
4830 ciphers in any specific order.
4832 The SilcDList is now used as silc_cipher_list dynamically
4833 allocated cipher list. Removed the static list all together
4834 and now all ciphers must be allocated to the dynamic list.
4835 The silc_cipher_alloc routine was changed to check only the
4838 All silc_cipher_* routines that used to return int returns
4841 The affected files lib/silccrypt/silccrypt.[ch].
4843 * The same thing was done to silc_hash_* as for silc_cipher_*
4844 routines. Affected files lib/silccrypt/silchash.[ch].
4846 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4847 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4848 Added also silc_pkcs_[un]register[_default] functions.
4849 Removed the data_context from the PKCS API.
4851 * Added silc_hmac_register_default function to register default
4852 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4853 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4854 to unregister all hmacs at once.
4856 * Register the default ciphers, hash functions, PKCSs and HMACs
4857 if client's configuration file does not exist. The affected
4860 * The client did not load the hash functions from the SIM
4861 modules at all. Added support for this. Affected file is
4862 silc/clientconfig.c.
4864 * When decoding public key with silc_pkcs_public_key_decode, check
4865 the supported algorithm only if PKCS are registered. Affected
4866 file lib/silccrypt/silcpkcs.c. The same was done with the
4867 silc_pkcs_private_key_decode.
4869 * Fixed the SILC List routines to keep the list always in order.
4870 It used to change the list's order when traversing the list but
4871 not it preserves the order. Affected file lib/trq/silclist.h.
4873 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Added the client library to use the SilcSocketConnection's
4876 reference counter (by silc_socket_dup) to prevent the bug that
4877 the socket object may be freed underneath async operation.
4879 * The name resolv library checking fixes in the configure.in.pre.
4882 * Created new version of the protocol drafts for future
4883 development. The -03 drafts are the ones that will be changed
4884 in the trunk now and the -02 will remain as they are.
4886 * Send list of CUMODE notifys to the router when announcing
4887 the channel users to the router. Affected file silcd/server.c.
4888 If the router receiving channel founder CUMODE for a channel
4889 that already has channel founder it will send CUMODE notify
4890 to the sender to remove the channel founder rights from the
4891 announced client. Affected file silcd/packet_receive.c.
4893 * The CUMODE notify may now use Server ID as well as the entity
4894 who changes the mode. Updated protocool specs.
4896 * Updated INSTALL and README files.
4898 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4900 * New web pages in the http://silc.pspt.fi. The pages was
4905 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Implemented the [DenyConnectin] config section in the server.
4908 Added silc_server_config_denied_conn to check whether incoming
4909 connection is denied. Affected file silcd/serverconfig.[ch].
4911 * Do not check the ports when checking the incoming configuration
4912 data if the port is 0, meaning any. Affected file is
4913 silcd/serverconfig.c.
4915 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Fixed buffer overflow in silc_string_compare in the file
4918 lib/silcutil/silcutil.c.
4920 * Fixed double free in silc_server_command_leave in the file
4923 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Fixed the version checking in the server. Affected file is
4928 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Fixed the configuration data fetching when accepting new
4931 connections in the server. Affected file silcd/server.c.
4933 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Added `sender_entry' argument to the function
4936 silc_server_packet_relay_to_channel so that we can check
4937 whether some destination actually belongs to the same route
4938 the sender belongs (ie, we must not resend the packet to the
4939 sender). Affected file silcd/packet_send.[ch].
4941 * Added `servername' field to the SilcClientEntry in the server
4942 to hold the name of the server where client is from. Affected
4943 file is silcd/idlist.h.
4945 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Moved the channel message encrypting in the router betwen
4948 router connections from silc_server_channel_message to the
4949 silc_server_packet_relay_to_channel since we want to check
4950 whether we have anybody channel before encrypting anything.
4951 Affected files silcd/packet_[receive/send].c.
4953 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4955 * Fixed the [AdminConnection] server config section to support
4956 multiple entries. Affected file silcd/serverconfig.c.
4958 * Added support into the server to check the validity of the
4959 incoming connection before executing any KE or authentication
4962 * The connection configuration is now saved to the KE and
4963 connection auth protocol contexts and not fetched anymore in
4964 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4966 * The local hosts listenning address and port is also resolved
4967 now when starting the server. We want to have the socket object
4968 to include the real address and port for the listener. Added
4969 new function silc_net_check_local_by_sock into the files
4970 lib/silcutil/silcnet.[ch].
4972 * Fixed a broadcast bug in server -> do not broadcast if we
4975 * Fixed a routing bug. Do not route broadcast packets ever.
4976 Broadcast packets must be processed always and not routed since
4977 they may be destined to some other host than yourself and thus
4978 would get routed without no good reason. Affected file is
4981 * Added function silc_server_config_is_primary_route to check
4982 whether primary router connection has been configured (a router
4983 configuration that we are initiating). If there is not, we
4984 will assume that there is only two routers in the SILC network
4985 and we will use the incoming router connection as our primary
4986 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4988 * Changed the order of the broadcasting. Broadcast _after_ the
4989 packet has been processed not before. Affected file is
4992 * Fixed a [ClientConnection] parsing bug. The port was never
4993 parsed correctly thus resulting to port 0. Affected file
4994 silcd/serverconfig.c.
4996 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4997 argument and did not set the broadcast packet flag. Affected
4998 file silcd/packet_send.c. Fixed same bug in the function
4999 silc_server_send_notify as well.
5001 * If we receive NEW_ID packet for our own ID in the server, ignore
5004 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Removed the nickname from the Private Message Payload.
5009 Updated the code and the protocol specs.
5011 * Updated protocol specs for submitting to the IETF.
5013 * Tweaked the Random Number Generator a bit. Affected file
5014 lib/silccrypt/silcrng.c. Exported a new function
5015 silc_rng_[global]_add_noise which can be used to add more
5018 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Do not parse packets with different timeout when protocol
5021 is active -> may cause problem with rekey. Affected file
5024 * When server receives signoff notify it must not create
5025 new channel key if the client is on any channels since the
5026 sender of the signoff notify will create it.
5028 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Added printing of error messages during SKE protocol from the
5031 failure packet sent by server during SKE. Affected file
5034 * Removed the client's failure_callback handling with timeout
5035 and handle it immediately when received.
5037 * The SKE library returned wrong type in SUCCESS and FAILURE
5038 packets. They must be 32 bit MSB not 16 bit MSB.
5040 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Ok, rewrote the logic of the re-key and now it seems to work.
5043 I tested it on high traffic with frequent re-keys without
5044 problems. Added hmac_receive (and renamed hmac to hmac_send)
5045 in SilcClientConnection in lib/silcclient/client.h and
5046 in SilcIDListData in silcd/idlist.h. Also, removed the
5047 SilcPacketParserContext's cipher and hmac fields as they are
5048 not needed anymore and actually caused some problems when
5049 the ciphers and hmac's changed underneath the packet parser.
5051 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * If re-key protocol is active then process the incoming packets
5054 synchronously since we must assure that icoming packets encrypted
5055 with the old key is processed before the new keys is set to
5056 use. This is true other packets than for REKEY packets.
5057 Affected file silcd/server.c. The same was done to client library
5058 as well, affected file lib/silcclient/client.c.
5060 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Fixed bug in client and server to accept the force send if
5063 the packet is send from silc_[server/client]_packet_process
5064 function. Otherwise the packets are never delivered, oops.
5066 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Disable force sending of packets when REKEY protocol is active.
5069 We must assure that no packet is sent directly when rekey is
5070 performed. All packets must be sent through packet queue.
5071 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5072 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5073 function is silc_[server/client]_packet_send_real to check
5076 * Replaced the SIM paths from example config files to
5077 /usr/local/modules. Also, make install creates now
5078 /usr/local/silc/logs directory to hold all the SILC server
5081 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Made the configure.in.pre work on Solaris. Patch by salo.

5086 CBC mode macros into lib/silccrypt/ciphers_def.h.
5088 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5090 * Fixed the make install.
5092 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * When MAC computation fails the silc_packet_decrypt returned 0
5095 even though it was supposed to return -1. Fixed this. The
5096 affected file is lib/silccore/silcpacket.c.
5098 * Do not replace the config files in /etc/silc (in make install)
5099 if they already exist. Affected file ./Makefile.am.
5101 * Do not send re-key packets immediately but through packet queue.
5102 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5104 * Changed silc_net_check_host_by_sock to return FALSE if the
5105 IP/DNS could not be resolved. Though, it returns the IP address
5106 now even if it could not resolve it (but returns also FALSE).
5107 Affected file lib/silcutil/silcnet.[ch].
5109 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5111 * Added silc_pkcs_decode_identifier to decode the public key's
5112 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5113 Added also silc_pkcs_free_identifier. Added also new context
5114 SilcPublicKeyIdentifier.
5116 * Added -S option to the silc client. It is used to dump the
5117 contents of the specified public key file.
5119 * Changed the PKCS api to return the public key length when
5120 setting the public key.
5122 * Fixed a fatal bug in the public and private key file loading.
5123 Affected file lib/silccrypt/silcpkcs.c.
5125 * Execute the packet parsing for client with zero (0) timeout
5126 if the protocol is active. Affected file silcd/server.c.
5128 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Made the key generation options to the silcd program. Added
5131 -C option, equivalent to client's option.
5133 * Added new [ServerKeys] config section to the server. It
5134 configures the server's public and private key.
5136 * Defined generic Public Key Payload into the protocol
5137 specification to send specific type of public keys and
5140 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5141 public key or certificate.
5143 * Implemented the GETKEY command to the server and to the
5144 client library and on user interface.
5146 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Made preliminary `make install' work.

5177 SilcClientConnection structure; not needed. Affected file is
5178 lib/silcclient/client.h.
5182 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5184 * Do not ask whether user wants to use the negotiated private key
5185 for private messages, just use it. Affected file is
5186 silc/local_command.c.
5188 * Added `send_enc_key' and `enc_key_len' fields to the
5189 SilcIDListData structure since they are needed in the re-key

5213 * Changed _ALL_ unsigned long and unsigned int to uint32,
5214 unsgined short to uint16 in the source tree.
5216 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5217 not handle clients that has entry->data.registered == FALSE.
5218 They are not in the network anymore. Affected file is
5221 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

5233 * Implemented the SERVER_SIGNOFF notify handling in the client
5234 library. Affected file lib/silcclient/client_notify.c. Also,
5235 implemnted the printing of the SERVER_SIGNOFF info to the
5236 application. Affected file silc/client_ops.c.
5238 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5239 if the deleting was successful. Affected file silcd/idlist.[ch].
5241 * Added support for public key authentication in the connection
5242 authentication protocol in the client library. Affected file
5243 lib/silcclient/protocol.c.
5245 * Changed the server's silc_idlist_get_clients_by_* interface
5246 to support already allocated array so that new entries may be
5247 added to pre-allocated array. Affected file silcd/idlist.[ch].
5248 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5249 and command replies.
5251 * All command reply functions in the server now calls the
5252 pending command callback even if error occured. This way the
5253 error will be delivered to the client as well. Affected files
5254 silcd/command.c and silcd/command_reply.c.
5256 * Fixed INFO command to return local server's info if no server
5257 was provided. Affected file lib/silcclient/command.c.
5259 * Removed RESTART command for good. Updated the code and the
5262 * Rewrote parts of the task system. It is a bit simpler now.
5263 Removed unsued task priorities. The affected files are
5264 lib/silcutil/silctask.[ch].
5266 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Moved the USERS printing from the library to the application.
5269 Affected files lib/silcclient/command.c and silc/client_ops.c.
5271 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5275 * Added channel key re-key support. The re-key is perfomed
5276 only by the router and is done once in an hour. Added `rekey'
5277 field to the SilcChannelEntry in the server. Affected files
5278 silcd/server.c and silcd/idlist.h.
5280 * Added silc_task_unregister_by_context into the file
5281 lib/silcutil/silctask.[ch].
5283 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5285 * Added SILC_UMODE_GONE mode to indicate when the client is not
5286 present in the SILC network. Added also support to the local
5287 command AWAY that will set this mode. Added support of showing
5288 "xxx is gone" in WHOIS command. The USERS command shows the
5289 gone status as well.
5291 * Fixed setting server and router operator privileges in the
5292 server's UMODE command. Affected file silcd/command.c.
5294 * Merged the SKE KE1 and KE2 payloads into one payload. The
5295 new KE payload is equivalent to the old KE2 payload.
5297 Cleaned up the SKE Start Payload parsing. It now uses the
5298 simple buffer unformatting to do the parsing. A lot faster
5301 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5302 to the SKE that is used to indicate whether both of the SKE
5303 parties should perform authentication. By default only the
5304 responder performs authentication. By setting this flag also
5305 the initiator must do authentication. By default it is unset
5306 since in normal SKE case, client to server connection, only
5307 the responder should do authentication. When doing SKE between
5308 two clients both should perform authentication. Updated the
5309 code and the protocol specs.
5311 * A little fix to IDENTIFY command in the server. Search the
5312 client first by hash not nickname. Affected file is
5315 * Fixed the silc_client_close_connection to support closing
5316 the client to client connections wihtout deleting too much
5317 data. Affected file lib/silcclient/client.c.
5319 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5320 are received if protocol used to be active but is not anymore
5321 the application would crash due to NULL pointer dereference.
5322 Affected files silcd/server.c and lib/silcclient/client.c.
5324 * Added `hash' field to the SilcClientConnection to include
5325 the hash function negotiated in the SKE protocol.
5327 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5328 to set the channel founder authentication data. A client can
5329 claim the founder rights later by providing the authentication
5330 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5331 This way the channel founder can regain the channel founder
5332 privileges even it is left the channel. This works only on
5333 local server and the client must be connected to the same
5334 server to be able to regain the founder rights. Updated the
5335 protocol specs accordingly.
5337 Added support to the CMODE command in the client to set the
5338 founder auth data. Read the README to see how to set it.
5340 Added support to the CUMODE command to claim the founder
5341 rights. Read the README to see how to do it.
5343 Added support for the founder authentication to the Channel
5344 Entry in the server. Affected file silcd/idlist.h.
5346 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5347 server's CMODE command. Affected file silcd/command.c.
5349 * Added the following new functions into lib/silccore/silcauth.[ch]:
5350 silc_auth_get_method and silc_auth_get_data.
5352 * The server now saves the remote hosts public key to the
5353 SilcIDListData pointer. Affected file silcd/protocol.c.
5355 * The normal server now does not remove the channel entry from
5356 the cache if the founder authentication data is set. It used
5357 to remove it if the founder was the last one on the channel on
5358 the server and left the channel. The auth data is saved and
5359 if the channel is re-joined later the old entry is used with
5360 the old auth data. Affected files silcd/command_reply.c and
5363 * Removed the `pkcs' field from the SilcIDListData structure
5364 in the server; it is not used. Affected file silcd/idlist.h.
5366 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Fixed packet processing on slow links. Partial packets were
5369 never re-processed because the incoming data buffer was cleared
5370 by the application. Application must not directly clear the
5371 sock->inbuf, the packet processing routines handle it. Fixed
5372 this in client library and in server.
5374 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5376 * Fixed the WHOIS and IDENTIFY send reply function to really
5377 check whether to send list or just one entry. Affected file
5380 * Cleaned up the LEAVE command's channel key distribution. The
5381 affected file silcd/command.c.
5383 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5384 can enforce the channel mode as well. In that case the ID
5385 includes the ID of the server. The code now enforces the
5386 mode change if the router have different mode than the server.
5388 * The notify client operation with CMODE_CHANGE notify can now
5389 return NULL client_entry pointer if the CMODE was not changed
5390 by client. Application must check for this.
5392 * Added <Server ID> argument to INFO command to support server
5393 info fetching by Server ID.
5395 * Added silc_server_announce_get_channel_users to get assembled
5396 packets of channel users of the specified channel. Affected
5397 file silcd/server.[ch].
5399 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5400 was freed underneath the ID Cache.
5402 * Re-announce clients when the server received CHANNEL_CHANGE
5403 notify from the router. Affected file silcd/packet_send.c.
5405 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5408 crashed since it did not handle the fact that there is no cipher
5409 called "3" and didn't check the error condition. Now fixed.
5411 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5412 flag. It can be used to send message requests.
5414 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Implemented the RESTART command in the client.
5418 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5419 notice type messages. Added notice printing to the user
5422 * The channel keys are not re-generated if the channel's mode
5423 is PRIVKEY, ie private key on the channel exists. Affected
5424 files silcd/server.c and silcd/command.c.
5426 * Fixed a little bug in channel message delivery when channel
5427 private keys are set in the server. Affected file is
5428 silcd/packet_send.c.
5430 * Changed the setting on channel->on_channel = TRUE from the
5431 silc_client_save_channel_key to the JOIN command reply. The
5432 key payload is not received if the private channel key is set.
5433 Affected file lib/silcclient/command_reply.c and the
5434 lib/silcclient/client_channel.c.
5436 * When the CMODE_CHANGE notify is sent and the channel private
5437 key mode is removed the channel key must be re-generated in
5438 other cells as well. Added this support for the router in the
5439 silcd/packet_receive.c.
5441 * Added new local command NOTICE to send notice message on
5442 channel. Affected file silc/local_command.[ch].
5444 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Added new local command ME to the client. It is used to send
5447 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5448 some action. Affected file silc/local_command.[ch].
5450 * Changed channel_message and private_message client operations
5451 to deliver the message flags to the application. Added also
5452 the `flags' arguments to the silc_client_send_channel_message
5453 and silc_client_send_private_message functions. Affected file
5456 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Redefined the Private Message Payload to support private message
5459 keys and to support the new private message flags. Updated
5460 the protocol specs. Flags makes it possible to have for example
5461 CTCP style messages.
5463 * Added new type SilcPrivateMessagePayload and defined an API
5464 for it in the lib/silcclient/silcprivate.[ch].
5466 * Tested private message private keys successfully. Tested the
5467 private message key set, unset and list commands with the new
5470 * Redefined the Channel Message Payload to include the channel
5471 message flags (equal with private message flags) to support
5472 for example CTCP style messages.
5474 * Defined some of the message (for channel and private message)
5475 flags. Updated the protocol specs and added the flags to the
5476 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5478 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Added SilcKeyAgreementStatus type to the key agreement routines
5481 to indicate the current status and error if one occured.
5482 The status types are defined in the lib/silcclient/silcapi.h.
5484 * Added new local command KEY that is used to set and unset private
5485 keys for channels, set and unset private keys for private messages
5486 with remote clients and to send key agreement requests and
5487 negotiate the key agreement protocol with remote client. The
5488 key agreement is supported only to negotiate private message keys,
5489 it currently cannot be used to negotiate private keys for channels,
5490 as it is not convenient for that purpose.
5492 * Fixed a minor pending callback setting bug in the function
5493 silc_client_get_client_by_id_resolve, now the function works.
5494 Affected file lib/silcclient/idlist.c.
5496 * Added function silc_net_get_local_port to get local bound
5497 port by socket. Added to lib/silcutil/silcnet.[ch].
5499 * Added `sockets' and `sockets_count' fields to the SilcClient
5500 object. They hold the sockets of the listenning sockets in
5501 the client. Listenning sockets may be for example the key
5502 agreement server. Affected file lib/silcclient/client.[ch].
5503 Added functions the silc_client_add_socket and the
5504 silc_client_del_socket. They are exported to the application
5507 * Added ~./silc/clientkeys to support other client's public keys.
5509 * Renamed verify_server_key client operation to verify_public_key
5510 and added one argument to indicate the type of the connection
5511 (server, client etc.).
5513 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added silc_server_connection_auth_request to handle the
5516 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5517 silcd/packet_receive.[ch].
5519 * Added silc_server_send_connection_auth_request into the
5520 silcd/packet_send.c to send the connection auth request packet.
5522 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5525 * Fixed the public key authentication in responder side in the
5526 server. The `auth_data' pointer includes the SilcPublicKey
5527 not the path to the public key. Affected file silcd/protocol.c.
5529 * Implemented the public key authentication in the initiator side
5530 in the server. Affected file silcd/protocol.c.
5532 * Removed the [RedirectClient] config section from the server
5533 configuration. Is not needed and I don't want to implement it.
5535 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Cleaned up the CMODE command in the server. It now works
5538 correctly and supports all the modes defined in the protocol.
5539 Affected file is silcd/command.c.
5541 * Added `hmac_name' field to the SilcChannelEntry in the server
5542 to hold the default HMAC of the channel. It can be set when
5543 creating the channel (with JOIN command). Affected files
5546 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5547 type to indicate the change of the current cipher and hmac
5548 on the channel. Client can safely ignore the <cipher> argument
5549 (if it chooses to do so) since the CHANNEL_KEY packet will
5550 force the channel key change anyway. The <hmac> argument is
5551 important since the client is responsible of setting the new
5552 HMAC and the hmac key into use.
5554 * Fixed the CMODE command in the client library as well.
5556 * Tested CMODE command in router environment successfully.
5558 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Show the version of the remote client (or server) when connecting
5561 to the server. It is logged to the log file. Affected file
5562 is silcd/protocol.c.
5564 * Fixed the KILLED notify handling in the client library. The
5565 client must be removed from all channels when receiving the
5568 Also, do not remove the client entry when giving the KILL
5569 command but when the KILLED notify is received.
5571 * Removed silc_idlist_find_client_by_nickname from the server.
5572 Not needed anymore. Affected files silcd/idlist.[ch].
5574 * Implemented the CHANNEL_CHANGE notify type handling to the
5575 server. Affected file silcd/server.c.
5579 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5581 * Added silc_server_send_notify_invite to send the INVITE
5582 notify between routers.
5584 * Implemented the INVITE command correctly to the server.
5586 * Implemented the INVITE notify type handling in the server.
5588 * Implemented the INVITE command to the client library and on the
5591 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Added function silc_server_get_client_resolve to find the
5594 client entry by ID from all ID lists and then resolve it
5595 (using WHOIS) if it cannot be found. Affected file is
5598 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Implemented the BAN command to the client library.
5602 * The JOIN command in the server now checks the invite list
5605 * Changed the silc_command_reply_payload_encode_va and the
5606 silc_command_payload_encode_va to support that if argument is
5607 NULL it ignores and checks the next argument. Affected file
5608 lib/silccore/silccommand.c.
5610 * Added silc_server_send_notify_ban to send the BAN notify
5611 type between routers.
5613 * Chaned the silc_notify_payload_encode to support that if
5614 argument is NULL it ignores and checks the next argument.
5615 Affected file lib/silccore/silcnotify.c.
5617 * Tested ban lists in router environment successfully.
5619 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Implemented BAN command to the server, in silcd/command.[ch].
5623 * Removed the BAN and INVITE_LIST modes from the CMODE command
5626 * Added function silc_string_match to regex match two strings.
5627 Affected files lib/silcutil/silcutil.[ch].
5629 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Redefined parts of the SilcChannelEntry in the server to support
5632 the new ban and invite lists.
5634 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Redefined the INVITE command. The same command can be used to
5637 invite individuals to the channel but also to manage the invite
5638 list of the channel (to add to and remove from the invite list).
5639 Updated the protocol specs.
5641 * Added new command SILC_COMMAND_BAN that can be used to manage
5642 the ban list of the channel. Updated the protocol specs.
5644 * Removed the channel modes: the SILC_CMODE_BAN and the
5645 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5646 in the CMODE command. The equivalent features are now available
5647 using INVITE and BAN commands. Updated the protocol specs.
5649 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5650 in the network about change in the current ban list. The notify
5651 type is not used by the client.
5653 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5654 support the invite lists.
5656 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added new function silc_string_regexify that converts string
5659 including wildcard characters into regex string that can
5660 be used by the GNU regex library. Added into the file
5661 lib/silcutil/silcutil.[ch].
5663 Added silc_string_regex_combine to combine to regex strings
5664 into one so that they can be used as one regex string by
5665 the GNU regex library. Added into the file
5666 lib/silcutil/silcutil.[ch].
5668 Added silc_string_regex_match to match two strings. It returns
5669 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5671 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Imported GNU regex to the soruce tree into lib/contrib.
5674 Fixed some compiler warning from the regex.c.
5676 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Fixed MOTD command in the server to work in router environment.
5680 * Fixed the MOTD command in the client library to support
5681 the server argument in the command.
5683 * Added `nickname_len' argument to the silc_idlist_add_client
5684 in the server, as the `nickname' argument may be binary data
5687 * Added silc_idlist_get_channels to return all channels from
5690 * Implemented LIST command to the server. Affected file is
5693 * Implemented the LIST command to the client library and on the
5696 * Added [<user count>] argument to the LIST command reply.
5697 With private channels the user count is not shown.
5699 * Updated TODO and README.
5701 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * The client entry's data.registered must be TRUE even with
5704 global client entry on global client list. The data.registered
5705 is used to check whether the client is anymore in the network,
5706 for example with WHOWAS command so it must be valid.
5708 * Fixed the WHOWAS command in the server. It now actually works
5709 in router environment. Added function into silcd/command_reply.c
5710 silc_server_command_reply_whowas_save.
5712 * Added silc_idlist_purge function to the silcd/idlist.c
5713 to periodically purge the ID Cache.
5715 * Fixed INFO command in the server. It works now in router
5716 environment. Added <server name> argument to the INFO command
5717 reply. Updated the protocol specs.
5719 * Fixed minor bug in silc_idcache_purge to not purge if the
5720 expire value is zero.
5722 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5723 they were buggy because of the WHOWAS information.
5725 * Fixed local command MSG to handle the async resolving of
5726 the remote client properly. It used to fail the first MSG.
5727 Affected file silc/local_command.c.
5729 * Added `data_len' field to SilcIDCache context.
5731 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5733 * Update TODO. Todo in commands in the server.
5735 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5738 used by routers as broadcast packet to inform other routers
5739 about the changed user mode.
5741 Implemented the notify handling in the server. Affected file is
5742 silcd/packet_receive.c. Added the function
5743 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5745 * Added new generic Channel Payload and deprecated the New Channel
5746 Payload. The New Channel Payload is now the generic Channel
5749 * Added new argument `mode' to the silc_server_send_new_channel
5750 as it is required in the Channel Payload now.
5752 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5753 and created a new and real SilChannelPayload to represent the
5754 new generic Channel Payload. Implemented the encode/decode
5755 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5757 * Added silc_server_get_client_channel_list to return the list
5758 of channels the client has joined for WHOIS command reply.
5759 Affected file silcd/server.[ch].
5761 * Implemented the channel list sending in the WHOIS command reply
5762 in server and in the client.
5764 Implemented the channel list displaying on the user interface
5765 as well. Affected file silc/client_ops.c.
5767 * Added silc_channel_payload_parse_list to parse list of Channel
5768 Payloads. It returns SilcDList list of SilcChannelPayloads.
5769 Client for example can use this function to parse the list of
5770 channels it receives in the WHOIS command reply. The caller
5771 must free the list by calling silc_channel_payload_list_free.
5772 Affected files lib/silccore/silcchannel.[ch].
5774 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Added one new argument <user mode> to the WHOIS command reply
5777 to return the mode of the user in SILC. Updated the protocol
5780 Implemented it to the server and client.
5782 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Fixed the mode printing on the user interface on joining.
5785 Affected file silc/client_ops.c.
5787 * Implemented the UMODE command and user modes in general to the
5788 client library and to the user interface.
5790 * Implemented the UMODE command to the server.
5792 * The server now sends UNKNOWN_COMMAND error status if client sends
5793 unknown command. Affected file silcd/command.c.
5795 * All server commands now handle the command identifier the right
5796 way when sending the command reply to the client. The client can
5797 use to identify the command replies with the identifier.
5799 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5801 * Added silc_server_get_client_route to resolve the route to
5802 the client indicated by the client ID. Affected file is
5805 * Added silc_server_relay_packet as general function to relay
5806 packet to arbitrary destination. This deprecates functions
5807 like _send_private_message_key, _relay_notify etc. Affected
5808 file is silcd/packet_send.[ch].
5810 Removed silc_server_send_key_agreement,
5811 silc_server_send_private_message_key and
5812 silc_server_packet_relay_notify functions from the file
5813 silcd/packet_send.[ch].
5817 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5818 server. Affected file silcd/packet_receive.[ch].
5820 * Implemented the KILL command to the client. Implemented the
5821 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5822 Affected files lib/silcclient/command[_reply].c and
5823 lib/silcclient/client_notify.c. Implemented the KILL notify
5824 printing in the user inteface.
5826 * Fixed a lot silc_parse_nick memory leaks from the client
5827 library in the file lib/silcclient/command.c.
5829 * Changed the silc_server_send_notify_on_channels's `sender'
5830 argument from SilcSocketConnection to SilcClientEntry to
5831 check the sender as entry and not as connection object and not
5832 to send to the client provided as argument. The affected file
5833 is silcd/packet_send.[ch].
5835 * The notify packets that are destined directly to the client used
5836 to not to be processed by the server. Now changed that and the
5837 server processes all notify packets. After relaying the packet
5838 to the client the notify packet is processed in the server.
5840 * The silc_server_free_client_data now checks whether there is
5841 pending outgoing traffic for the client and purges the data to
5842 the network before removing the client entry.
5844 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5847 an client is killed from the SILC Network. Updated the protocol
5850 Added new function silc_server_send_notify_killed to the
5851 silcd/packet_send.[ch].
5853 * Added function silc_server_packet_relay_notify to relay notify
5854 packets that are destined directly to a client. In this case
5855 the server does not process the notify packets but merely relays
5856 it to the client. Affected file silcd/packet_send.[ch].
5858 Added also silc_server_packet_process_relay_notify to check
5859 whereto relay the notify. Affected file is
5860 silcd/packet_receive.[ch].
5862 * Implemented the KILL command to the server.
5866 * Added the backup schema desgined last fall to the protocol
5867 specs for everyone to see. The specification is in the
5868 *-spec-xx.txt draft and the packet type definitions for the
5869 backup routers is in *-pp-xx.txt draft. Thusly, added also
5870 new packet type SILC_PACKET_CELL_ROUTERS.
5872 * A big security problem in the implementation discovered. The
5873 signoff of an client did not cause new channel key generation
5874 which it of course should've done. The channel keys must be
5875 always re-generated when client leaves (or signoffs) the channel.
5876 The silc_server_remove_from_channels funtion now handles
5877 the channel key re-generation.
5879 * Added `sender' argument to the silc_server_send_notify_on_channels
5880 to not to send the client provided as argument. Affected file
5881 silcd/packet_send.[ch].
5883 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Implemented OPER and SILCOPER commands into the server and
5888 * Added silc_auth_verify and silc_auth_verify_data to verify
5889 the authentication directly from the authentication payload.
5890 It supports verifying both passphrase and public key based
5891 authentication. Affected file lib/silccore/silcauth.[ch].
5893 * Added `hash' field to the SilcIDListData structure. It is the
5894 hash negotiated in the SKE protocol. Affected file is
5897 * Slight redesigning of the SilcAuthPayload handling routines.
5898 Do not send SilcPKCS but SilcPublicKey as argument.
5900 * Implemented the public key authentication support to the
5901 serverconfig. The public key is loaded from the provided path
5902 and saved as authentication data to void * pointer. Thus,
5903 changed the unsigned char *auth_data to void *auth_data;
5905 * Fixed SHUTDOWN command to send the reply before the server
5906 is shutdown. :) Affected file silcd/command.c.
5908 * Fixed fatal bug in CONNECT command. The hostname was invalid
5909 memory and server crashed. Affected file silcd/command.c.
5911 * Fixed fatal bug in CLOSE command. The server_entry became
5912 invalid but was referenced later in the command. Affected file
5915 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5917 * Fixed fatal bug in failure packet handling. Server ignored
5918 the failure and thus crashed when it came.
5922 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5925 that the command may be executed only once in (about) 2 seconds.
5926 The old SILC_CF_LAG flag is same but allows command bursts up
5927 to five before limiting.
5929 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5930 server code. Various commands now includes the CF_LAG_STRICT
5931 flag to disallow any kind of miss-use of the command.
5933 * Fixed the silc_buffer_unformat to not to allocate any data
5934 if the length of the data is zero. It used to allocate the
5935 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5937 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Changed the format of AdminConnection configuration section
5940 in the server. Added username of the admin to the format.
5941 Affected files silcd/serverconfig.[ch].
5943 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5944 to return admin configuration data by host, username and/or
5947 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Implemented WHOWAS command to the server. Added the functions:
5951 silc_server_command_whowas_parse,
5952 silc_server_command_whowas_send_reply,
5953 silc_server_command_whowas_from_client and
5954 silc_server_command_whowas_from_server
5956 * Added <Client ID> argument to the WHOWAS command reply. Updated
5957 the protocol specs accordingly.
5959 * Implemented WHOWAS command and command_reply to the client
5962 Implemented the WHOWAS printing on the user interface.
5964 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Added new argument to the WHOWAS command reply, the real name.
5967 It is an optional argument. Updated the protocol specs.
5969 * Added SilcIDCacheDestructor callback that is registered when
5970 the SilcIDCache is allocated. The callback is called when
5971 an cache entry in the ID Cache expires, or is purged from the
5972 cache. Added into lib/silccore/idcache.[ch].
5974 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5975 to destruct the client entries when the cache entry expires.
5976 Other ID Cache's in server and in the client library ignores
5979 * If the ID Cache entry's `expire' field is zero then the entry
5980 never expires. Added boolean `expire' argument to the
5981 silc_idcache_add function in the lib/silccore/idcache.[ch].
5982 If it is TRUE the default expiry value is used.
5984 * Added silc_server_free_client_data_timeout that is registered
5985 when client disconnects. By default for 5 minutes we preserve
5986 the client entry for history - for WHOWAS command.
5988 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Added support to the server to enforce that commands are not
5991 executed more than once in 2 seconds. If server receives
5992 commands from client more frequently, timeout is registered
5993 to process the commands. Affected file silcd/command.c.
5994 Added new function silc_server_command_process_timeout.
5996 * Changed NICK_NOTIFY handling in client library to check that
5997 if the client's nickname was changed, so there is no need to
5998 resolve anything from the server.
6000 * Removed error printing from the WHOIS and IDENTIFY commands.
6001 If error occurs then it is ignored silently in the client library.
6002 The application, however, may map the received error to
6003 human readable error string. The application currently maps
6004 the NO_SUCH_NICKNAME error to string.
6006 * Made the command status message public to the application. Moved
6007 them from lib/silcclient/command_reply.c to
6008 lib/silcclient/command_reply.h. The application can map the
6009 received command status to the string with the
6010 silc_client_command_status_message function.
6012 * Added check to the server to check that client's ID is same
6013 as the Source ID in the packet the client sent. They must
6016 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * Added dist-bzip hook to the Makefile.am to make bzip2
6019 compressed distributions.
6021 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Server now enforces the maximum length for the nickname and
6024 the channel as protocol specification dictates. 128 bytes for
6025 nickname and 256 bytes for channel name.
6027 * Moved the WHOIS printing to the application. The client libary
6028 does not print out the WHOIS information anymore, the application
6029 must do it. Renamed silc_client_command_reply_whois_print to
6030 the silc_client_command_reply_whois_save.
6032 The client's idle time is also sent to the application now, and
6033 the idle is shown on screen.
6035 * Added silc_client_command_reply_identify_save to save the
6036 received IDENTIFY entries.
6038 * Do not check for channel private keys in message sending and
6039 reception if the channel does not have the PRIVKEY mode set.
6040 Affected file lib/silclient/client_channel.c.
6042 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6044 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6045 just surfaced after chaning the JOIN procedure.
6047 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6049 * Added silc_client_get_clients_by_list to get client entries
6050 from Client ID list, that is returned for example by JOIN
6051 and USERS command replies. The application should use this
6052 function for example when JOIN command reply is received to
6053 resolve the clients already on the channel (library does not
6054 do that anymore as USERS command reply is not used in the JOIN
6055 procedure anymore). Affected files lib/silcclient/silcapi.h and
6056 lib/silcclient/idlist.c.
6058 * JOIN command reply and USERS command reply returns now SilcBuffer
6059 pointers instead of unsigned char pointers when returning
6060 the client list and mode list.
6062 * Added <Client ID> argument to the JOIN command reply, mainly
6063 for the server to identify for which client the command was
6064 originally sent. Updated protocol specs accordingly.
6066 * Added SilcDlist private_key pointer to the SilcChannelEntry
6067 in the client to support the channel private keys. Affected
6068 file is lib/silcclient/idlist.h.
6070 * Added SilcChannelPrivateKey argument to the function
6071 silc_client_send_channel_message so that application can choose
6072 to use specific private ke if it wants to. If it is not provided,
6073 the normal channel key is used, unless private keys are set.
6074 In this case the first (key that was added first) is used
6075 as the encryption key.
6077 * Implemented the support for channel private key handling.
6078 Implemented the following functions:
6080 silc_client_add_channel_private_key,
6081 silc_client_del_channel_private_keys,
6082 silc_client_del_channel_private_key,
6083 silc_client_list_channel_private_keys and
6084 silc_client_free_channel_private_keys
6086 Affected file lib/silcclient/client_channel.c.
6088 * Added the support for the private keys in the channel message
6089 sending and encryption and in the message reception and
6090 decryption. Affected funtions are
6091 silc_client_send_channel_message and silc_client_channel_message.
6093 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added SKE's key verify callback to the client library's
6096 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6098 * Removed the statement that server (or router) must send USERS
6099 command reply when joining to the channel so that the client
6100 knows who are on the channel. Instead, the client list and
6101 client's mode list is now sent in the JOIN command reply to the
6102 client who joined channel. This is better solution.
6104 * Added function silc_server_get_users_on_channel and function
6105 silc_server_save_users_on_channel to the silcd/server.[ch].
6107 * Removed function silc_server_command_send_users from the
6110 * Do not show topic on the client library anymore. The topic is
6111 sent in the command reply notify to the application and the
6112 application must show the topic now.
6114 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Added client searching by nickname hash into the IDENTIFY and
6117 WHOIS commands in the server as they were clearly missing from
6118 them. Affected file is silcd/command.c.
6120 * Fixed a bug in private message receiving in the client library.
6121 The remote ID was freed and it wasn't supposed, now it is
6124 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Minor fix to the channel payload; allocate the data area, as it
6127 needs to be of specific length.
6129 * If the key agreement port is zero then the operating
6130 system will define the bound port. Affected files are
6131 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6133 * Added new function silc_channel_payload_decrypt into the file
6134 lib/silccore/silcchannel.[ch].
6136 * Moved the channel message etc, check from silc_packet_decrypt
6137 to applications. The library calls now a generic
6138 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6139 when the packet is either normal or special. This was done to
6140 allow more wide range of checking that was not allowed when
6141 the code was in library. Now applications can do virtually any
6142 checks to the packet and return to the library the decision how
6143 the packet should be processed. Affected files are
6144 lib/silccore/silcpacket.[ch].
6146 Added silc_server_packet_decrypt_check to the server and
6147 silc_client_packet_decrypt_check to the client library.
6149 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6150 to send with specified source and destination information.
6152 * Channel message delivery between routers was broken after the
6153 channel key distribution was fixed earlier. The channel key
6154 was used be to distributed to other routers as well which is not
6155 allowed by the protocol. Now this is fixed and channel keys
6156 really are cell specific and the channel message delivery between
6157 routers comply with the protocol specification.
6159 * Fixed various commands in server to check also the global list
6160 for the channel entry and not just the local list. The affected
6161 file silcd/command.c.
6163 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Added assert()s to buffer formatting and unformatting routines
6166 to assert (if --enable-debug) when error occurs. Affected
6167 file: lib/silcutil/silcbuffmt.c.
6169 * Changed to auto-reconnect to check whether the remote host is
6170 router and register the re-connect timeout if it is. It used
6171 to check that whether we are normal server, but router must do
6172 auto-reconnect with another router as well. Affected file
6175 * Removed the [<key len>] option from CMODE command as the cipher
6176 name decides the key length, nowadays. See the defined ciphers
6177 from the protocol specification.
6179 * Added [<hmac>] option to the CMODE command to define the HMAC
6180 for the channel. Added SILC_CMODE_HMAC channel mode.
6182 * Added [<hmac>] option for the JOIN command so that user can
6183 select which HMAC is used to compute the MACs of the channel
6186 * Added Hmac field to the Channel Message Payload. The integrity
6187 of plaintext channel messages are now protected by computing
6188 MAC of the message and attaching the MAC to the payload. The
6189 MAC is encrypted. Now, it is clear that this causes some
6190 overhead to the size of the packet but rationale for this is that
6191 now the receiver can verify whether the channel message decrypted
6192 correctly and also when private keys are set for the channel the
6193 receiver can decrypt the packet with several keys and check from
6194 the MAC which key decrypted the message correctly.
6196 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6197 lib/silccrypt/silccipher.[ch].
6199 * Added silc_hash_len to return the digest length into the
6200 lib/silcrypt/silchash.[ch].
6202 * Rewrote parts of Silc Channel Payload interface in the
6203 lib/silccore/silcchannel.[ch]. The encode function now also
6204 encrypts the packet and parse function decrypts it.
6206 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Fixed a minor formatting bug in the SKE's key material processing.
6209 It actually might have processed the keys wrong way resulting
6212 * Redefined the mandatory HMAC algorithms and added new algorithms.
6213 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6214 and hmac-md5 truncated to 96 bits. The mandatory is now
6215 hmac-sha1-96. Rest are optional (including the one that used
6216 to be mandatory). Rationale for this is that the truncated HMAC
6217 length is sufficient from security point of view and can actually
6218 make the attack against the HMAC harder. Also, the truncated
6219 HMAC causes less overhead to the packets. See the RFC2104 for
6222 * Added new [hmac] configuration section. The SKE used to use
6223 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6224 is of course wrong. The official names that must be proposed in
6225 the SKE are the ones defined in the protocol specification
6226 (hmac-sha1-96 for example). The user can configure any hmac
6227 using any hash function configured in the [hash] section. At
6228 least, the mandatory must be configured.
6230 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6232 * Added HMAC list to the SKE proposal list. It has now both
6233 hash algorithm list and HMAC list. This makes the protocol
6234 incompatible with previous versions. The SKE now seems to work
6235 the way it is supposed to work, for the first time actually.
6237 * Defined plain Hash algorithms to the protocol specification.
6240 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Implemented support for key agreement packets into the server.
6243 Added functions silc_server_key_agreement and
6244 silc_server_send_key_agreement. Other than these functions,
6245 server has nothing to do with this packet.
6247 * Added support for private message key packets into the server.
6248 Added functions silc_server_private_message_key and
6249 silc_server_send_private_message_key.
6253 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6254 called in the protocol's final callback instead in the END
6255 protocol state. This makes a little more sense and in the same
6256 time in client we can use the same protocol routines for normal
6257 key exchange and to key agreement packet handling as well.
6259 * Added to both client's and server's KE protocol context the
6260 SilcSKEKeyMaterial pointer to save the key material. We will
6261 bring the key material to the protocol's final callback by doing
6262 this. The final callback must free the key material.
6264 * Added SKE's packet_send callback into client's KE protocol
6265 context so that the caller can choose what packet sending function
6266 is used. This way we can use different packet sending when
6267 doing normal SKE when doing key agreement packet handling (in
6268 the key agreement packet handling we do not want to encrypt
6271 * Implemented the responder side of the key agreement routines
6272 in the client. The client can now bind to specified port and
6273 accept incoming key negotiation. The key material is passed
6274 to the application after the protocol is over.
6276 * Implemented the processing of incoming Key Agreement packet
6277 in the client. Added function silc_client_key_agreement to
6280 * Implemented the intiator side of the key agreement routines
6281 in the client. The client can now initiate key agreement with
6282 another remote client. The key material is passed to the
6283 application after the protocol is over.
6285 * Created client_keyagr.c to include all the key agreement
6288 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6289 SILC_TASK_CALLBACK except that it is not static.
6291 * Created client_notify.c and moved the Notify packet handling
6292 from the client.[ch] into that file.
6294 * Created client_prvmsg.c and moved all private message and
6295 private message key routines from the client.[ch] into that file.
6297 * Create client_channel.c and moved all channel message and
6298 channel private key routines from the client.[ch] into that file.
6300 * Changed silc_client_get_client_by_id_resolve to resolve with
6301 WHOIS command instead of IDENTIFY command, in the file
6302 lib/silclient/idlist.c.
6304 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Implemented the SKE's responder side to the Client library.
6308 * When FAILURE is received to the protocol do not trust it
6309 blindly. Register a timeout to wait whether the remote closes
6310 the connection as it should do it, only after that process the
6311 actual failure. This was changed to both client and server.
6313 * Added client_internal.h to include some of the structures
6314 there instead of client.h in lib/silcclient/.
6316 * Added function silc_task_unregister_by_callback to unregister
6317 timeouts by the callback function.
6319 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Some "Incomplete WHOIS info" errors has been appearing on the
6322 log files. Took away the entry->userinfo check from WHOIS
6323 reply sending. The entry->userinfo is now " " if client did not
6324 provide one. I thought this was fixed earlier but something
6325 is wrong still. Let's see if the error still appears.
6327 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Fixed a minor bug in the login when the channel key is
6330 re-generated in the server. It used to generate the key in
6331 wrong order and thus caused problems in the channel traffic.
6333 * Fixed a minor bug in channel key distsribution after
6334 KICK command. The key was not sent to the router even though
6337 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Added silc_ske_process_key_material_data as generic routine
6340 to process any key material as the SILC protocol dictates. The
6341 function is used by the actual SKE library but can be used by
6342 applications as well. This relates to the private message keys
6343 and the channel private keys since they must be processed the
6344 same way the normal SILC session keys. The protocol dictates
6345 this. Affected files: lib/silcske/silcske.[ch].
6347 Added also silc_ske_free_key_material to free the
6348 SilcSKEKeyMaterial structure.
6350 * Defined silc_cipher_set_key function to set the key for
6351 cipher without using the object's method function. The affected
6352 files: lib/silccrypt/silccipher.[ch].
6354 * Implemented silc silc_client_add_private_message_key,
6355 silc_client_add_private_message_key_ske,
6356 silc_client_del_private_message_key,
6357 silc_client_list_private_message_keys and
6358 silc_client_free_private_message_keys functions in the
6361 Added functions silc_client_send_private_message_key to send
6362 the Private Message Key payload and silc_client_private_message_key
6363 to handle incoming Private Message Key payload.
6365 * Added Cipher field to the Private Message Key payload to set
6366 the cipher to be used. If ignored, the default cipher defined
6367 in the SILC protocol (aes-256-cbc) is used.
6369 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Removed lib/silcclient/ops.h file.
6373 Redefined parts of the SILC Client Library API. Created new
6374 file silcapi.h that deprecates the ops.h file and defines the
6375 published Client Library API. Defined also private message key
6376 API and channel private key API into the file.
6378 This is the file that the application must include from the
6379 SILC Client Library. Other files need not be included by
6380 the application anymore.
6382 * Added new key_agreement client operation callback and also
6383 defined the Key Agreement library API for the application.
6385 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6387 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6388 is used by clients to request key negotiation between another
6389 client in the SILC network. If the negotiation is started it
6390 is performed using the SKE protocol. The result of the
6391 negotiation, the secret key material, can be used for example
6392 as private message key.
6394 Implemented the Key Agreement payload into the files
6395 lib/silccore/silauth.[ch].
6397 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Redefined ciphers for the SILC protocol. Added some new ciphers
6400 and defined the key lengths for the algorithms. Changed the
6401 code accordingly. The default key length is now 256 bits.
6403 * Fixed SKE key distribution function silc_ske_process_key_material
6404 when the key length is more than 128 bits. The default key
6405 length in SILC is now 256 bits.
6407 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6408 to indicate unsupported algorithm.
6410 * Renamed rijndael.c to aes.c and all functions as well.
6412 * Fixed a long standing channel key setting bug in client library.
6413 Weird that it has never surfaced before.
6415 * Fixed bug in channel deletion. If the entire channel is removed
6416 then it must also delete the references of the channel entry
6417 from the client's channel list as the client's channel entry and
6418 the channel's client entry share same memory.
6420 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6422 * Implemented CONNECT and SHUTDOWN commands in the client.
6424 * Implemented CLOSE command to the client.
6426 * Added the function silc_idlist_find_server_by_name into the
6427 files silcd/idlist.[ch].
6429 Added the function silc_idlist_find_server_by_conn into the
6430 files silcd/idlist.[ch].
6432 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * DIE command was renamed to SHUTDOWN. Updated the both code
6437 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6438 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6440 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6443 * Added function silc_server_create_connection function to create
6444 connection to remote router. My server implementation actually
6445 does not allow router to connect to normal server (it expects
6446 that normal server always initiates the connection to the router)
6447 so the CONNECT command is only good for connecting to another
6450 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6453 or some other client was kicked from the channel.
6455 Implemented the handling of the notify type to both client
6458 Implemented silc_server_send_notify_kicked to send the KICKED
6459 notify. It is used to send it to the server's primary router.
6461 * Implemented the KICK command into server and client.
6463 * Added `query' argument to the silc_idlist_get_client function
6464 to indicate whether to query the client from server or not if
6467 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6468 to indicate that the client is not channel founder.
6472 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Removed the rng context from SilcPacketContext structure and
6475 changed that the packet routine uses the Global RNG API.
6477 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6479 * Added support for quit message that client can "leave" on the
6480 channel when it quits the SILC. It is ditributed inside the
6481 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6483 Added silc_server_free_client_data that will take the
6484 signoff message as argument.
6486 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6488 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Updated parts of the protocol specification to keep it up
6493 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6496 payloads in one packet.
6498 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6499 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6500 use now the new List flag.
6502 * Also deprecated the following packet types: REPLACE_ID,
6503 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6505 * Added list support for Notify packet in server.
6507 * Added silc_server_send_notify_channel_change to send the
6508 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6509 the silc_server_send_replace_id.
6511 * Added silc_server_send_notify_nick_change to send the
6512 NICK_CHANGE notify type. Deprecates the function
6513 silc_server_send_replace_id.
6515 * Added silc_server_send_notify_join to send the JOIN notify type.
6516 Deprecates the function silc_server_send_new_channel_user.
6518 * Added silc_server_send_notify_leave to send LEAVE notify type.
6519 Deprecates the function silc_server_send_remove_channel_user.
6521 * Added silc_server_send_notify_cmode and
6522 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6523 types. Deprecates the silc_server_send_set_mode function.
6525 * Added SERVER_SIGNOFF notify type to indicate that server has
6526 quit. This means that all clients on the channel from that
6527 server will drop. This can be also used when netsplit happens.
6529 Deprecated REMOVE_ID packet type since it is not needed anymore
6532 Added silc_server_send_notify_server_signoff to send the
6533 SERVER_SIGNOFF notify type. Deprecates the function
6534 silc_server_send_remove_id.
6536 Added also silc_server_send_notify_signoff to send the
6537 SIGNOFF notify type.
6539 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6540 SILC protocol from this day on. Changed the protocol
6541 specification as well.
6543 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6544 notify type. It is used between routers to notify about
6545 topic changes on a channel.
6547 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6550 * Partly updated the protocol specification to comply with the
6551 changes now made. It is still though a bit outdated.
6553 * The JOIN notify type now takes one extra argument <Channel ID>.
6554 The packet used to be destined to the channel but now the
6555 JOIN type may be sent as list thus it is impossible to
6556 destine it to any specific channel. By adding this argument
6557 it is again possible.
6559 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6561 * Added CREDITS file. The CHANGES and CREDITS file will appear
6562 in the distribution as well.
6564 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6567 types in the server's silcd/packet_receive.c.
6569 * Implemented CMODE and CUMODE to work in router environment.
6571 * Fixed minor encoding and decoding buglet from the
6572 lib/silccore/silcmode.c.
6574 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6577 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6579 * Changed all SilcConfigServer* and silc_config_server* to
6580 SilcServerConfig* and silc_server_config*, respectively.
6583 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Associated the ID (client or server ID) to the Authentication
6586 Payload to avoid any possibility of forging. Updated the
6587 protocol specification and the code accordingly.
6589 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6591 * The RSA key length is now save to the RsaKey context in the
6592 key generation process in lib/silccrypt/rsa.c. The key length
6593 is now used to figure out the maximum size of the block allowed
6594 to be encrypted/signed.
6596 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6597 is equivalent to the silc_mp_mp2bin but does not allocate any
6600 * Changed silc_mp_mp2bin API to take length argument. If it is
6601 non-zero then the buffer is allocated that large. If zero, then
6602 the size is approximated using silc_mp_sizeinbase, which however
6605 * Created Global RNG API which is global RNG that application can
6606 initialize. After initializing, any routine anywhere in the
6607 code (including library) can use RNG without allocating a new
6608 RNG object. This was done to allow this sort of use of the
6609 RNG in code that has no chance to allocate RNG object. All
6610 applications currently allocate this and many routines in the
6611 library use this. Affected file lib/silccrypt/silcrng.[ch].
6613 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6614 it to use the Global RNG API.
6616 * Defined Authentication Payload into protocol specification that
6617 is used during SILC session to authenticate entities. It is
6618 used for example by client to authenticate itself to the server
6619 to obtain server operator privileges.
6621 Implemented this payload into the lib/silccore/silcauth.[ch].
6622 Implemented also routines for public key based authentication
6623 as the new protocol specification dictates.
6625 Moved definitions of different authentication methods from
6626 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6628 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6629 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6630 silc_pkcs_verify_with_hash functions into the file
6631 lib/silccrypt/silcpkcs.[ch].
6633 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6635 * The client entry's userinfo pointer must be always valid.
6636 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6637 will fail since it requires the userinfo. Now, the userinfo
6638 is allocated as "" if actual userinfo does not exist. Actually,
6639 it must exist and it is totally Ok to drop client connections
6640 that does not announce the userinfo. However, we will make
6641 this workaround for now.
6643 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6644 to return the remote port by socket.
6646 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6649 SILC_SERVER_PENDING_EXEC and added an new macro
6650 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6651 data or when error occurs while processing the pending command.
6653 Added new argument `destructor' into silc_server_command_pending
6654 and to the SilcServerCommandPending object. This destructor is
6655 now called after calling the pending callback or if error occurs
6656 immediately. If error occurs the actual pending callback won't
6657 be called at all - only the destructor. The destructor may be
6658 NULL if destructor is not needed.
6660 All this applies for client library code as well. Similar
6661 changes were made there as well for the pending commands.
6663 In the client, the application must now allocate the
6664 SilcClientCommandContext with the silc_client_command_alloc
6667 * Added reference counter to the SilcServerCommandContext. Added
6668 function silc_server_command_alloc and silc_server_command_dup
6671 Same type of functions added to the client library for the same
6674 * Removed the cmd_ident from IDListData away since it is now
6675 global for all connections. It is the command identifier used
6676 in command sending and with pending commands. The affected file
6679 * Added reference counter to the SilcSocketConnection objecet to
6680 indicate the usage count of the object. The object won't be
6681 freed untill the reference counter hits zero. Currently only
6682 server uses this, and client ignores it. The client must be
6683 set to use this too later. The affected files are
6684 lib/silccore/silcsockconn.[ch]. Added also the function
6685 silc_socket_dup to increase the reference counter.
6687 This was mainly added because it is possible that the socket
6688 is removed underneath of pending command or other async
6689 operation. Now it won't be free'd and proper DISCONNECTING
6690 flags, etc. can be set to avoid sending data to connection that
6691 is not valid anymore.
6693 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6694 the connection. After that it sets SILC_SET_DISCONNECTED.
6695 It is, however, possible that the socket data is not still freed.
6696 The silc_server_packet_process now checks that data is not
6697 read or written to connection that is DISCONNECTED. The socket
6698 get's freed when the reference counter hits zero.
6700 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Changed the client operation API: channel_message operation's
6703 `sender' is now the client entry of the sender, not the nickname
6704 and the `channel' is the channel entry, not the channel name.
6706 In the private_message operation the `sender' is now also the
6707 client entry of the sender not the nickname.
6709 Affected file is lib/silcclient/ops.h and all applications
6710 using the client operations.
6712 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Moved the calling of ops->connect() from connect_to_server_final
6715 into receive_new_id functin since that is the point when the
6716 client is actually allowed to send traffic to network. The
6717 affected file is lib/silcclient/client.c.
6719 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6721 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6722 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6723 (if needs broadcasting) instead of broadcasting the packets one
6724 by one which would make a burst in the network traffic.
6726 * Added `broadcast' argument to the functions in silcd/server.[ch]
6727 silc_server_create_new_channel[_with_id] to indicate whether
6728 to send New Channel packet to primary router.
6730 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Added new function into the silcd/server.[ch] files:
6733 silc_server_create_new_channel_with_id to create new channel with
6734 already existing Channel ID.
6736 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6737 lib/silccore/silcpacket.h. This packet is used t send list of
6738 Set Mode payloads inside one packet. Server uses this to set
6739 the modes for the channels and clients on those channels, that it
6740 announced to the router when it connected to it. The protocol
6741 specification has been updated accordingly.
6743 * The silc_server_new_channel did not handle the packet coming
6744 from normal server as it normally does not send that. However,
6745 when it announces its channels it does send it. Implemented
6746 the support for that.
6748 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6749 into the file lib/silccore/id.h.
6751 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Fixed memory leaks in the functions silc_idlist_del_client,
6754 silc_idlist_del_channel and silc_idlist_del_server in the file
6755 silcd/idlist.c. All of those leaked like a sieve.
6757 * Fixed some small memory leaks in the client's function
6758 silc_client_notify_by_server.
6760 * Added functions into silcd/server.c: silc_server_announce_clients,
6761 silc_server_announce_channels and silc_server_announce_server.
6762 These functions are used by normal and router server to announce
6763 to its primary router about clients, channels and servers (when
6764 router) that we own. This is done after we've connected to the
6767 These functions effectively implements the following packet types:
6768 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6769 and SILC_PACKET_NEW_ID_LIST.
6771 * Added new functions into the silcd/packet_receive.[ch]:
6772 silc_server_new_id_list, silc_server_new_channel_list and
6773 silc_server_new_channel_user_list to handle the incoming
6774 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6776 * Added support of changing Channel ID in the function
6777 silc_server_replace_id. If the server that announces a channel
6778 to the router already exists in the router (with same name but
6779 with different Channel ID), router is responsible to send
6780 Replace ID packet to the server and force the server to change
6781 the Channel ID to the one router has.
6783 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6784 client that the Channel ID has been changed by the router. The
6785 normal server sends this to the client. Client must start using
6786 the new Channel ID as the channel's ID.
6788 Implemented handling of this new type into lib/silcclient/client.c
6789 into the function silc_client_notify_by_server.
6791 * Added new function silc_idlist_replace_channel_id into the files
6792 silcd/idlist.[ch] to replace the Channel ID.
6794 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Call silc_server_command_identify_check always when processing
6797 the IDENTIFY command in silcd/command.c
6799 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6802 send keepalive packets. The packet can be sent by clients,
6803 servers and routers.
6805 Added function silc_socket_set_heartbeat into the file
6806 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6807 If not set, the heartbeat is not performed. The actual
6808 heartbeat is implemented in the low level socket connection
6809 library. However, application is responsible of actually
6812 Added silc_server_send_heartbeat to send the actual heartbeat
6813 packet into silcd/packet_send.[ch]. Server now performs
6814 keepalive with all connections.
6816 * Added silc_task_get_first function into lib/silcutil/silctask.c
6817 to return the timeout task with shortest timeout. There was a bug
6818 in task unregistration that caused problems. TODO has been
6819 updated to include that task system must be rewritten.
6821 * The client library will now resolve the client information when
6822 receiving JOIN notify from server for client that we know but
6823 have incomplete information.
6825 * Rewrote parts of silc_server_remove_from_channels and
6826 silc_server_remove_from_one_channel as they did not remove the
6827 channel in some circumstances even though they should've.
6829 * Encryption problem encountered in server:
6831 The LEAVE command used to send the Channel Key packet to the
6832 router immediately after generating it. However, the code
6833 had earlier sent Remove Channel user packet but not immediately,
6834 ie. it was put to queue. The order of packets in the router
6835 was that Channel Key packet was first and Remove Channel User
6836 packet was second, even though they were encrypted in the
6837 reverse order. For this reason, MAC check failed. Now, this
6838 is fixed by not sending the Channel Key packet immediately but
6839 putting it to queue. However, this is more fundamental problem:
6840 packets that are in queue should actually not be encrypted
6841 because packets that are sent immediately gets encrypted
6842 actually with wrong IV (and thus MAC check fails). So, packets
6843 that are in queue should be encrypted when they are sent to
6844 the wire and not when they put to the queue.
6846 However, the problem is that the current system has not been
6847 designed to work that way. Instead, the packet is encrypted
6848 as soon as possible and left to the queue. The queue is then
6849 just purged into wire. There won't be any fixes for this
6850 any time soon. So, the current semantic for packet sending
6853 o If you send packet to remote host and do not force the send
6854 (the packet will be in queue) then all subsequent packets to the
6855 same remote host must also be put to the queue. Only after the
6856 queue has been purged is it safe again to force the packet
6859 o If you send all packets immediately then it safe to send
6860 any of subsequent packets through the queue, however, after
6861 the first packet is put to queue then any subsequent packets
6862 must also be put to the queue.
6864 Follow these rules and everything works fine.
6866 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * Added new function silc_server_remove_clients_by_server to
6869 remove all client entries from ID list when the server connection
6870 is lost. In this case it is also important to invalidate all
6871 client entires as they hold the invalid server entry. This
6872 fixes fatal bug when server has lost connection and will reconnect
6875 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * Made some sanity checks to silc_server_daemonise like to check
6878 whether the requested user and group actually exists.
6880 * Added sanity check to SKE's silc_ske_responder_finish to check
6881 that the public and private key actually is valid.
6883 * Invalidate the client's nickname when receiving Replace ID
6884 packet and the Client ID is being replaced. This means that the
6885 server will query the nickname if someone needs it (client)
6888 * Sort the ID Cache in client library when the ID Cache data
6889 has changed (needs sorting).
6891 * Do not allow for SILC client to create several connections to
6892 several servers. The client does not support windows right now
6893 and generating multiple connections causes weird behaviour.
6895 Irssi-silc client does support windows and can handle several
6896 connections without problems, see: www.irssi.org and SILC plugin.
6898 * Fixed some places where client was added to the IDList. The
6899 rule of thumb is following (in order to get everything right):
6900 If the client is directly connected local client then the
6901 `connection' argument must be set and `router' argument must be
6902 NULL to silc_idlist_add_client function. If the client is not
6903 directly connected client then the `router' argument must
6904 bet set and the `connection' argument must be NULL to the
6905 silc_idlist_add_client function.
6907 * The funtion silc_server_packet_send_local_channel actually did
6908 not check whether the client was locally connected or not. It
6909 does that now. Fixed a bug related to LEAVE command.
6911 * Fixed Remove Channel User payload parsing bug in server's
6912 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6914 * The server's silc_server_save_channel_key now checks also the
6915 global ID list for the channel as it might not be in the local
6916 list. Fixed a bug related to LEAVE command.
6918 * Is this the end of the [<unknown>] buglet that has been lurking
6919 around for a long time? A little for loop fix in server's
6920 silc_server_command_whois_parse that is used by both IDENTIFY
6921 and WHOIS command. At least, this was a clear bug and a cause
6922 of one type of [<unknown>] buglet.
6924 * WHOIS and IDENTIFY commands call the function
6925 silc_server_command_[whois/identify]_check function even if
6926 we are not router server.
6928 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6930 * Added --with-gmp configuration option. If set the GMP
6931 is always compiled in the SILC source tree. If not set then
6932 it is checked whether the system has the GMP3 installed. If
6933 it has then the GMP won't be compiled (the system's headers
6934 and library is used), if it doesn't have it then the GMP is
6935 compiled in the SILC source tree.
6937 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6939 * Changed RSA private exponent generation to what PKCS #1
6940 suggests. We try to find the smallest possible d by doing
6941 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6942 not security fix but optimization.
6944 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6946 * Added new config entry [Identity] to fork the server and run
6947 it as specific user and group. A patch from Bostik.
6949 * Imported Dotconf configuration library into lib/dotconf.
6950 This will be used to create the SILC configuration files later.
6951 It will appear in the distsribution after this commit.
6953 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * A big code auditing weekend happening. Auditing code for
6956 obvious mistakes, bugs and errors. Also, removing any code
6959 Removed files for being obsolete:
6961 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6962 inline in the file lib/silcutil/silcbuffer.h)
6964 o lib/silcutil/silcbufutil.c (the header has inline versions)
6966 Changed code to fix possible error conditions:
6968 o The buffer formatting routines now check that the destination
6969 buffer really has enough space to add the data. This applies for
6970 both buffer formatting and unformatting
6971 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6972 unformatting was changed to accomodate following rules:
6973 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6974 sent to the function while XXX_*STRING will not allocate or copy
6975 the data into the buffer. Instead it sets the pointer from the
6976 buffer into the pointer sent as argument (XXX_*STRING used to
6977 require that the pointer must be allocated already). This change
6978 makes this whole thing a bit more consistent and more optimized
6979 (note that the data returned in the unformatting with XXX_*STRING
6980 must not be freed now). The routines return now -1 on error.
6982 o Tried to find all code that use buffer_format and buffer_unformat
6983 and added return value checking to prevent formatting and
6984 especially unformatting errors and possible subsequent fatal
6987 o Changed ske->x and ske->KEY to mallocated pointers in
6988 lib/silcske/silcske.h. Fixed possible data and memory leak.
6990 o Added return value checking to all *_parse* functions. Fixed
6991 many memory leaks as well.
6993 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6994 so that buffer overflows would not happen. All code now also
6995 checks the return value as it can fail.
6997 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6999 * Added reconnection support to server if the normal server looses
7000 its connection to the router (for example if router is rebooted).
7001 The server performs normal reconnection strategy implemented
7002 to the server. Affected file silcd/server.c.
7004 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Added new packet type SILC_PACKET_SET_MODE that is used to
7007 distribute the information about changed modes (for clients,
7008 channels and clients channel modes) to all routers in the
7009 network. Updated the protocol specification accordingly.
7011 Added functions into silcd/packet_send.c and
7012 silcd/packet_receive.c: silc_server_send_set_mode,
7013 silc_server_set_mode.
7015 Added new files silcmode.[ch] into lib/silccore that implements
7016 the encoding and decoding of Set Mode Payload. Added new type
7017 SilcSetModePayload. Moved the definitions of different modes
7018 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7020 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Oops, a little mistake in server's connection authentication
7023 protocol. The protocol is not ended with FAILURE but with
7024 SUCCESS if the authentication is Ok. :) Affected file is
7027 * Implemented NICK_CHANGE notify handling in server in the file
7028 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7029 the local clients on the channel. After the changing nickname
7030 in router environment snhould work and the [<unknown>] nickname
7031 should appear no more.
7033 The silc_server_replace_id function that receives the Replace ID
7034 payload now sends the NICK_CHANGE notify type also in the file
7035 silcd/packet_receive.c
7037 * Changed WHOIS and IDENTIFY command to support the maximum amount
7038 of arguments defined in protocol specs (3328 arguments). This
7039 fixed a bug that caused problems when there were more than three
7042 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Added extra parameter, command identifier, to the
7045 silc_client_send_command so that explicit command identifier
7048 Changed that ID list routines uses specific command identifier
7049 when sending WHOIS/IDENTIFY requests to the server so that they
7050 can be identified when the reply comes back.
7052 Affected files lib/silcclient/command.[ch],
7053 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7055 * Added `sender' argument to silc_server_packet_send_to_channel
7056 to indicaet the sender who originally sent the packet to us
7057 that we are now re-sending. Ignored if NULL. Affected file
7058 silcd/packet_send.[ch].
7060 * Added some server statistics support in silcd/server_internal.h
7061 SilcServerStatistics structure and around the server code. Also
7062 send some nice statistics information when client is connecting
7065 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7067 * Fixed channel ID decoding in server's JOIN command reply in
7068 silcd/command_reply.c
7070 * Fixed braodcasting of replace ID payload to not to send it if
7071 we are standalone server in silcd/packet_receive.c.
7073 * Fixed all channel message sending routines to not to send
7074 packets to clients that has router set, since they are routed
7075 separately in the same function earlier. Affects file
7076 silcd/packet_send.c and all channel packet sending functions.
7078 * In USERS reply, res_argv[i] are not allocated, the table
7079 is allocated. Thus changed that free the table, not its
7082 * In server's whois_check and identify_check if the client is
7083 locally connected do not send any WHOIS commands - they are not
7086 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7088 * Fixed some minor bugs in client when sending WHOIS command. The
7089 arguments was in wrong order.
7091 * Removed statis function add_to_channel from server in
7092 silcd/command.c that was previously used with the joining but
7095 * Tested USERS command in router environment successfully with two
7096 routers, two servers and two clients.
7098 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7100 * Reorganized the USERS command and command reply in client library
7101 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7102 When the command is given by user we register a pending command
7103 callback that will reprocess the command after the reply has been
7104 received from the server. When reprocessing the packet we then
7105 display the information. Thus, the USERS information is displayed
7106 now in the command callback instead of in the command reply
7107 callback. The processing of the command is same as previously
7108 when server has sent the command reply in the JOINing process.
7110 * Added to USERS command in silcd/command_reply.c to join the client,
7111 we didn't use to know about, to the channel after we've created
7112 a client entry for it. Also, for clienet we did know already still
7113 check whether it is on the channel or not and add it if not.
7115 * Removed silc_server_command_join_notify as the function and its
7118 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7120 * Changed the client's pending command handling to the same as the
7121 server's pending command handling. It is also now possible to
7122 execute command reply functions from other command reply
7123 function as the function callbacks for commands and command
7124 replies are one and same. The pending commands are not static
7125 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7126 in client connection context. Thus, pending commands are server
7127 connection specific as it is convenient.
7129 Changed the function silc_client_command_pending and
7130 silc_client_command_pending_del and added new function
7131 silc_client_command_pending_check. Removed the
7132 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7135 * Added cmd_ident, current command identifier, to the client
7136 connection context in lib/silcclient/client.h to keep track on
7137 command identifiers used in command sending. Client's command reply
7138 function handling now supports the mandatory command identifiers.
7140 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7141 funtions in client to fully support pending command callbacks.
7143 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7144 as one of the arguments to the application in the command reply
7147 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7148 before first releasing SILC but came back. Now it is removed again
7149 and should come back nomore. The FORWARDED flag was used only
7150 by the JOINing procedure by forwarding the command packet to router.
7151 Now, the JOINing procedure has been changed to more generic (due
7152 to various router environment issues) and FORWARDED is not needed
7153 anymore for anything. The protocol specification is yet to be
7156 Now, removed silc_server_packet_forward from server and the flag
7157 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7159 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7161 * Renamed NAMES command to USERS command. The NAMES was named that
7162 due to historical reasons. Now it is renamed. Also, rewrote
7163 parts of the USERS command. The nickname list is not sent anymore
7164 by the server. Only Client ID and mode lists are sent in the USERS
7165 command. Changed this also to the protocol specification.
7167 The client now resolves the names and stuff after it receives
7168 the USERS list from the server when joining to the channel.
7170 * WHOIS and IDENTIFY commands has been changed to support multiple
7171 Client ID's per command. One can now search for multiple users
7172 in the network by sending only one WHOIS or IDENTIFY command.
7173 Changed the code and the protocol specifications.
7175 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7176 uses silc_server_command_whois_parse to parse the request. */
7178 * If normal server, do not parse the WHOIS and IDENTIFY requests
7179 before sending it to the router. Saves some time.
7181 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Fixed JOIN command on client library. Wrong number of arguments
7184 used to crash the client.
7186 * Added silc_server_channel_has_global function to check whether
7187 channel has global users or not.
7189 * Added silc_server_channel_has_local function to check whether channel
7190 has locally connected clients on the channel.
7192 * The silc_server_remove_from_one_channel now checks whether the
7193 channel has global users or not after given client was removed from
7194 the channel. It also checks whether the channel has local clients
7195 on the channel anymore. If it does not have then the channel entry
7196 is removed as it is not needed anymore.
7198 * The silc_server_notify now checks on JOIN notify whether the joining
7199 client is one of locally connected or global. If it is global then
7200 the channel has now global users on the channel and that is marked
7201 to the channel entry. Also, it now saves the global client to
7202 global list who is joining and JOINs it to the channel. This is
7203 for normal server, that is.
7205 Changed silc_server_send_notify_on_channel,
7206 silc_server_packet_relay_to_channel and
7207 silc_server_packet_send_to_channel check if we are normal server
7208 and client has router set (ie. global client) do not send the
7209 message to that client, as it is already routed to our router.
7211 * Implemented LEAVE notify type handling in silc_server_notify
7214 * Tested LEAVE command in router environment successfully. Tested
7215 with two routers, two servers and two clients.
7219 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7221 * Implemented SIGNOFF notify type handling in silc_server_notify
7224 * silc_server_remove_id now removes the client entry from all channels
7225 it has joined and thusly sends SIGNOFF notify type.
7227 * Rewrote the NAMES list generation in server by removing two excess
7228 loops. The lists are created now inside one loop.
7230 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7232 * silc_server_remove_channel_user checks now also global list
7233 for channel and client.
7235 * silc_server_new_channel_user checks now both local and global
7236 list for channel and client. Fixed a bug in client id decoding.
7237 Used to decode wrong buffer.
7239 * silc_server_channel_message checks now both local and global
7240 list for channel entry.
7242 * Tested channel joining (hence JOIN) in router environment
7243 successfully. Tested with two routers, two servers and two
7246 * Tested channel message sending in router environment successfully.
7248 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Added silc_server_save_channel_key into server.[ch] to save the
7251 received channel key in Channel Key payload processing. It is
7252 also used in JOIN command reply handling.
7254 Equivalent function silc_client_save_channel_key added into
7255 client.[ch] into client library.
7257 * Changed JOIN command reply to send information whether the channel
7258 was created or not (is existing already) and the channel key
7259 payload. Changed protocol specs accordingly.
7261 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7262 the request was sent by ID and not by nickname. Crashed on
7265 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7267 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7268 now correctly save the received data.
7270 * silc_server_free_sock_user_data now notifies routers in the
7271 network about entities leaving the network.
7273 At the same time implemented functions silc_server_remove_id
7274 and silc_server_send_remove_id to receive and send REMOVE_ID
7275 packets. The packet is used to notify routers in the network
7276 about leaving entities. The ID removed will become invalid in
7279 * Added function silc_idlist_del_server into server. Removes and
7280 free's server entry from ID list.
7282 * silc_server_private_message function now checks, if we are router,
7283 that the destination ID really is valid ID, naturally.
7285 * In router when NEW_ID packet is received (for new client) the
7286 hash of the Client ID is saved in the ID Cache but the
7287 client->nickname is set to NULL, instead of putting the hash
7290 IDENTIFY command now also checks that client->nickname must be
7291 valid. If it is not if will request the data from the server who
7292 owns the client. Added new function
7293 silc_server_command_identify_check.
7295 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7296 to set the command to already allocated Command Payload.
7298 * Tested private message sending in router environment with two
7299 routers, two servers and two clients. Fixed minor bugs and now
7302 * Fixed segfault from client's NAMES command. Used to crash if
7305 * Forwarded packets must not be routed even if it is not destined
7306 to the receiver. Changed server code comply with this.
7308 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Added `require_reverse_mapping' boolean value to ServerParams
7311 structure. If TRUE (not default) the server will require that
7312 the connecting host has fully qualified domain name.
7314 If the reverse mapping is not required and hostname could not be
7315 found the IP address is used as hostname.
7317 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Implemented version string checking to both client and server.
7320 The check is incomplete currently due to the abnormal version
7321 strings used in development version of SILC.
7323 * Changed all command functions in server to use the new
7326 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7328 * Changed char *data to unsigned char *data in ID Cache system to
7329 support binary data as ID Cache data. Changed code to support
7330 binary data in lib/silccore/idcache.c.
7332 * Renamed silc_server_packet_relay_command_reply to
7333 silc_server_command_reply as it is normal packet receiving
7334 function. Rewrote the function to accept command replys for
7335 servers and not only for clients.
7337 * Mark remote router always as registered server if we are connecting
7338 to it. Otherwise, commands sent by the router to us are ignored.
7340 * All ID List find routines now returns the ID Cache Entry pointer
7341 as well if requested.
7343 * WHOIS command works now in router environment, tested with two
7344 routers, two servers and two clients.
7346 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7347 in router environment (as it is almost equivalent to WHOIS) but
7348 hasn't been tested thoroughly. Added new functions:
7350 silc_server_command_identify_parse
7351 silc_server_command_identify_send_reply
7352 silc_server_command_identify_from_client
7353 silc_server_command_identify_from_server
7355 * Disabled route cache adding because adding two different ID's with
7356 same IP replaces the old cache entry thus giving wrong route.
7357 The entry->router->connection is always the fastest route anyway
7358 so route cache may not be needed. Of course, new routes maybe
7359 established after receiving the ID when the entry->router->connection
7360 might not be anymore the most optimal.
7362 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7364 * Add route cache for received ID for fast routing.
7366 * Added silc_server_packet_route to route received packet on router
7367 that is not destined to us.
7369 * Renamed silc_server_get_route to silc_server_route_get.
7371 * Added id_string and id_string_len fields into SilcServer to
7372 include encoded ServerID for fast comparing without excess
7373 encoding of the ID's.
7375 * Cleaned up WHOIS command on server side. Added following static
7378 silc_server_command_whois_parse
7379 silc_server_command_whois_check
7380 silc_server_command_whois_send_reply
7381 silc_server_command_whois_from_client
7382 silc_server_command_whois_from_server
7384 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7385 arguments in command replies. All command functions should be
7386 updated to use this macro.
7388 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7390 * Minor typo fixes on command reply handling on server.
7392 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7394 * Added silc_server_command_add_to_channel internal routine to add
7395 the client to the channel after router has created the channel and
7396 sent command reply to the server.
7398 * Added generic silc_server_send_command to send any command from
7401 * Use static buffer with ID rendering instead of duplicating data.
7403 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7405 * Fixed a channel user mode bug when joining to a channel server gave
7406 everybody channel founder rights, oops.
7408 * We mark ourselves as the router of the incoming server connection
7409 if we are router ourselves. This way we can check in some packet
7410 sending functions whether it is locally connected server. For
7411 incoming router connections we put NULL.
7413 * For router sending packets locally means now always sending the
7414 packet cell wide; to local clients and local servers. For normal
7415 server sending packet locally means sending it to only local
7418 * Fixed the JOIN command to really work in router environment. If the
7419 channel is created it is always created by the router. Router is
7420 also responsible of making the initial joining to the channel,
7421 sending JOIN notify to the sending server and distributing
7422 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7423 does not exist server doesn't do anything else but forward the
7424 command to the router which performs everything.
7426 * Added silc_server_send_channel_key function to send the Channel Key
7429 * Added silc_server_create_channel_key to create new channel key. The
7430 channel key is now re-generated everytime someone joins or leaves
7431 a channel, as protocol dictates. Note: channel->key_len is the
7434 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7437 packet_receive.[ch] to separate packet sending and receiving
7438 routines. The server.[ch] now includes everything else including
7439 actual packet processing (writing and reading data) and other
7442 Renamed silc_server_private_message_send_internal to
7443 silc_server_send_private_message. The routine is still though
7444 used only to relay private messages as server does not send
7445 private messages itself.
7447 Renamed silc_server_new_channel to silc_server_create_new_channel
7448 and added new function sicl_server_new_channel that handles the
7449 incoming New Channel packet. Added also new sending function
7450 silc_server_send_new_channel to send New Channel Payload.
7452 * Added new function silc_server_notify to process incoming notify
7453 packet to the server/router. Server may then relay the notify
7454 to clients if needed.
7456 * Added new function silc_server_new_channel_user to process incoming
7457 New Channel User packet. Router will redistribute the packet and
7458 send JOIN notify to its local clients and locally connected servers
7459 if needed. Normal server will send JOIN notify to its local client
7460 on same channel when received this packet. Added also corresponding
7461 sending function silc_server_send_new_channel_user to sent the
7464 * Added boolean route argument to send_notif_to_channel and
7465 packet_send_to_channel functions to attempt to route the packet
7466 if it is TRUE and send only locally if it is FALSE.
7468 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7470 * silc_server_replace_id now broadcasts the received replace ID
7471 packet if it is not broadcast packet already. The router must
7472 broadcast to inform other routers about changed ID.
7474 * Added backpointer to server's router into SilcServer context in
7475 silcd/server_internal.h.
7477 * Fixed silc_server_packet_broadcast to send correct broadcast
7480 * The channel key is now distributed to the local client as soon
7481 as it is received from the router (in router environment) so that
7482 no other packet may be sent for the channel until client has
7485 * silc_server_remove_channel_user now broadcasts the received
7486 Remove Channel User packet if it is not broadcast packet already.
7487 The router must broadcast to inform other routers about removed
7490 * Added users field into SilcPacketContext that is a reference count
7491 of the context. One can increase the reference count by calling
7492 silc_packet_context_dup which is now changed to just increase the
7493 reference count instead of duplicating the data. The reference
7494 count is decresed by calling silc_packet_context_free that will
7495 free the data after the reference count hits zero.
7497 For now on the packet context and everything allocated into it
7498 (including the raw packet from network) must be freed by calling
7499 the new silc_packet_context_free function. Added also new function
7500 silc_packet_context_alloc that must be used now to allocate the
7501 context. This also means that if a routine is asynchronous from
7502 silc_[client/server]_packet_parse_type the packet context must
7503 be duplicated by calling silc_packet_context_dup. Otherwise it
7504 gets free'd after silc_[client/server]_packet_parse_type returns.
7505 Also, one must remember that if packet is duplicated then its
7506 reference count must be decresed by calling the free function as
7507 many times as it was duplicated.
7509 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7510 from both client and server.
7512 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7514 * Made joining to a channel working in router environment.
7516 * Cleaned up JOIN command on server side and create function
7517 silc_server_command_join_channel internal routine to make the
7520 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7522 * Changed silc_command_pending list to SilcDList. Also, added
7523 `ident' field to SilcServerCommandPending structure to identify
7524 the reply and to call correct callback.
7526 Added silc_server_command_pending_check function to replace the
7527 corresnponding macro. The silc_command_pending list is not
7530 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7531 to set identifier to previously allocated Command Payload. It
7532 is used to set identifier for command when resending Command
7535 * Added silc_command_payload_encode_payload to encode Command
7536 Payload buffer from SilcCommandPayload structure.
7538 * Added silc_argument_payload_encode_payload to encode Argument
7539 payload buffer from SilcArgumentPayload structure.
7541 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7543 * Changed WHOIS command to support router connection on server side.
7544 The whois request is always sent to router unless the server is
7545 standalone server. After server has received the reply from the
7546 router will it send the reply to the client.
7548 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7549 broadcast received broadcast packet. The function is used only
7550 by router. The broadcast packet is always sent to the router's
7553 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7554 render given ID to printable string, for log files for example.
7556 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7558 * Made basic router to router connections working. At least they
7559 can now connect to each other but nothing really works the way
7560 they are supposed - yet.
7562 * Added new initiator token to RouterConnection configuration
7563 file in silcd/serverconfig.[ch]. It is used to tell whether we
7564 are the initiator to the remote router or whether we'll expect
7565 the other end to connect.
7567 * Moved registering of listener task to silc_server_init, hence
7568 the server starts listenning as soon as it is run, even if it
7569 does not have connections to other routers. Let's see how well
7572 * Changed default connection retry timeouts for more suitable in
7575 * Removed cipher and such arguments from silc_idlist_add_client
7576 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7577 Added new function silc_idlist_add_data to add the keys and stuff
7580 * Added SilcIDListData structure and added it to SilcClientEntry
7581 and SilcServerEntry as their first field in the structure. This
7582 way we can explicitly cast the ID entries to the SilcIDListData
7583 structure and get common data for the entries. In past, we had
7584 to first check what type of connection it is and then cast it to
7585 correct ID entry type. Now, we can directly cast the opaque
7586 pointer to the SilcIDListData (no matter what ID entry it actually
7587 is) and get the data needed.
7589 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7591 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7592 in some circumstances even if threre were timeout tasks, though not
7593 IO tasks, but tasks anyway. Now fixed.
7595 * Defined SilcServerConnection structure to hold connection specific
7596 stuff about directly connected servers and routers. The definition
7597 is currently in silcd/server_internal.h. I thought about having
7598 a bit more important role fro this struct but for now it is used
7599 only when connecting to other server (or router actually).
7601 * Added connecting retry support in server when connecting to
7602 router(s). The retry feature implement exponential backoff
7603 algorithm. Also, added SilcServerParams structure to hold default
7604 parameters for server. For now, it include these retry settings
7605 and are hard coded. After server is moded to be as Silc Server
7606 Library this structure will be more important.
7608 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * Changed client librarys channel->clients table to SilcList and
7611 changed code accordingly.
7613 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Changed client's channel table to SilcList and changed code
7616 accordingly. Also changed SilcChannelClientEntry to include back-
7617 pointer to the channel so that client entry can use that structure
7618 as list as well and we have fast cross-reference to the channel.
7619 This change dramatically decreased the complexity of channel
7620 handling with client entry and vice versa (removed one extra
7621 loop when searching for channel entry from many functions).
7623 * Changed server->sim from table to SilcDList and changed code
7626 * NAMES command can now be used from user interface. It will show
7627 the user list on the channel, neatly.
7629 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7630 Code now saves realname of the user if it becomes available.
7632 * Renamed configure.in to configure.in.pre and made ./prepare
7633 script to automatically add correct version string to
7634 configure.in which it creates from configure.in.pre.
7636 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7638 * NAMES command reply now shows users mode with the nickname when
7641 * Moved silc_client_ch[u]mode[_char] functions from
7642 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7643 place sucks, they are utility functions and should be in some
7646 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7648 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7651 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Added TRQ (efficient deque and list library) into lib/trq. This is
7656 a very good list library that is currently used in the SILC. Defined
7657 SilcList API over the library because I didn't like the API very
7658 much. See lib/trq/silclist.h for the API and examples of how to
7659 use the API. Fixed various places in the code to use the new
7660 SilcList API. The SilcList is meant for lists that has a structure
7661 already defined as a list. It is not suitable to add just some
7662 context to the list (in TRQ, the context is the list actually).
7664 So, I defined SilcDList that can be used for the purpose where
7665 predefined list structure does not exit. This can be used as
7666 such list. Now some context just can be added to the SilcDList.
7667 Currently this list is not used in the SILC just yet, though there
7668 are a lot places where this can replace dynamically allocated
7669 tables and I will fix these places, later, to use SilcDList.
7670 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7671 and use TRQ internally).
7673 Also fixed some annoying warning messages that the original TRQ
7674 code generated. Also minor changes to TRQ's Makefile.in.
7676 * Added support for querying by Client ID to both WHOIS and
7677 IDENTIFY commands into server, as required by the protocol.
7679 * Removed method function pointers from SilcBuffer structure. They
7680 weren't used to anything and just increased the context size for
7681 no good reason. This change also made silc_buffer_alloc and
7682 silc_buffer_free functions inline functions.
7684 * Disabled command flooding detection support until it's fixed so
7685 that it accepts commands in but does not execute them more than once
7688 * Added silc_net_localhost(), to return local hostname, into
7689 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7690 that must be initialized before calling silc_client_init.
7692 * Added new function: silc_server_send_notify_on_channels to send
7693 notify messages to all channels client has joined. It is assured
7694 that the message is sent only once per client.
7696 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7697 lib/silcutil/silcutil.[ch] as silc_format function. The new
7698 function is generic and is used by server as well, not only by
7699 the logging routines.
7701 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7702 the provided version string was not acceptable. Added new function:
7703 silc_ske_check_version into lib/silcske/silcske.h. The function
7704 must be implemented by the application (client or server) and it
7705 does not reside in the SKE library. The function checks the version
7706 string remote end sent.
7708 * Added back pointers (to opaque context and to SilcSocketConnection)
7709 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7711 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7712 duplicate packet context structure.
7714 * Changed `notify' client operation to send same arguments as client
7715 receives from server except for ID's. ID's are mapped to correct
7716 ID entry and that is returned. Also, if channel entry is not sent
7717 by server but the notify is for channel the channel entry is sent
7718 to application (otherwise application doesn't know that it is for
7719 channel (library gets it from packet's Destination ID)).
7721 * Added silc_client_remove_from_channels into client library to
7722 remove a client from all channels it has joined to. Used when
7723 received SIGNOFF notify from server. Added also new function
7724 silc_client_replace_from_channels to replace old ID entry with
7725 new ID entry on all channels. Used when received NICK_CHANGE
7728 * Fixed ID Cache list handling in silc_idlist_get_client in
7729 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7730 to get (or query) client by ID.
7732 * Updated TODO list.
7734 * Added connection authentication status message defined by the
7735 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7736 support for these into the code in client and server side.
7738 * Added generic function silc_client_send_command to send any command
7739 with variable argument list. Application should use this function
7740 to send commands if the command functions provided by the library
7741 does not suite for the application's user interface needs.
7743 * Added new `failure' client operation. Application is notified about
7744 received failure packet if client is executing a protocol. In this
7745 case the protocol's execution has failed.
7747 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7748 is required by the protocol.
7750 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7751 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7754 * Added status flag to SilcSKE object to indicate realtime status
7755 of the SKE protocol.
7757 * Application receives now exactly same command reply arguments as
7758 the library receives from server. However, if ID is received the
7759 corresponding ID entry is returned to the application (eg. Client
7760 ID is mapped to correct SilcClientEntry entry and that is returned).
7761 Changed command_reply client operation due to this change.
7763 * Changed all ID's in commands and in command replys as ID Payloads.
7764 Change affected both client and server side codes.
7766 All ID's sent in SILC network (with execption of ID's in SILC
7767 Packet header) are sent in ID Payload to support variable length
7770 * Server now notifies nick changes and notifies all clients on
7771 the channels about the new nickname (about the new Client ID,
7774 * Implemented CMODE command to change channel modes. Supports all
7775 channel modes defined by the protocol specs except ban and invite
7776 lists. (Also, private channel key mode is supported but support for
7777 setting private channel key in client is missing, thus, this mode
7778 has no effect on client side (except that server requires that the
7779 client uses private channel key and normal channel traffic does not
7782 Also, invite mode works per se, but INVITE command does not work
7783 yet correctly, so you can set channel as invite only channel but
7784 inviting clients to the channel does not work (it is yet to be
7785 thought what's the best way to do it).
7787 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7788 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7789 Implemented CUMODE command to change user's mode on the channel.
7790 Supports all modes defined by the protocol specs.
7792 * Added NAMES command reply to return users modes on the channel.
7794 * Removed unnecessary and slow ciphers from lib/silccrypt.
7796 * Set SO_KEEPALIVE option to connection sockets by default.
7798 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7800 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7801 redefined the Notify Payload into protocol specs.
7803 * Added silc_id_payload_parse_id to get ID directly from raw
7806 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7808 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7809 accept searching by Client ID as well.
7811 * Added support for LEAVE and SIGNOFF notify types in client library.
7813 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7814 to parse ID Payload from raw data.
7816 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Added flags parameter into silc_ske_assemble_security_properties
7819 function in lib/silcske/silcske.[ch].
7821 * Changed notify client operation to fit better for notify messages
7822 sent by server. The notify payload received from server is now
7823 passed to the application (after parsing it to SilcNotifyPayload).
7824 It is application's responsibility to retrieve the arguments
7825 from the payload and show the message the way it wants. The message
7826 sent by server is implementation specific.
7828 * Changed public keys to comply with the protocol specification.
7829 Old public keys are not supported anymore and are not compatible.
7831 * Removed nickname from Channel Payload as the latest draft removed
7832 it. The client must resolve the nickname from the NAMES command
7833 reply received when it joined the channel.
7835 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7837 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7839 * Fixed some errors in protocol specification drafts.
7841 * Created lib/silccore/silcnotify.c to implement Notify Payload
7842 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7843 generic payloads described by protocol specifications. The file
7844 includes implementations for ID Payload and Argument Payload.
7846 * Changed Command Payload implementation to use the new Argument
7847 Payload. Changed command_xxxx_payload to command_payload_xxxx
7848 to comply with SILC coding conventions.
7850 * Added suppport for Argument Payload handling in Notify Payload
7851 implementation as protocol requires it. Added the new support
7852 into server and client lib as well.
7854 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7856 * Added support for multiple nicknames on same channel. [n] is
7857 added locally to the nickname if there are more than one same
7858 nicknames on the channel.
7860 * Server now sends all nicknames that matched WHOIS request.
7861 Client also shows the list received from server.
7863 * Added TOPIC command to client side. User can now set and show
7864 current topic on channel.
7866 * Added MOTD command to client and server. Also, server sends the
7867 motd when client connects to the server.
7869 * Changed version strings to comply ISO 8601.
7871 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7873 * Fixed protocol error handling in client library. It should now
7874 cope even if the SKE fails for some reason.
7876 * Made new protocol specification drafts for submitting to IETF.
7878 * Implemented TOPIC command to server in silcd/command.c.
7880 * Added two new notify types into lib/silccore/silcnotify.h:
7881 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7882 notify nickname change and topic setting/change on a channel.
7884 * API change of command_reply operation in client library. The
7885 application gets now the status type received from server as well.
7887 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7889 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7891 * Cras fixed and optimized the packet handling even further and
7892 it should work now. Minor change to the prototype of function
7893 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7895 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Added new function into lib/silcutil/silcschedule.[ch]:
7898 silc_schedule_with_fd to select() a specified fd. The function
7899 returns after timeout expires or data arrives or goes. The
7900 function is used by packet routines to wait that all data is
7901 received from network.
7903 * Fixed data reading from network in lib/silccore/silcpacket.c.
7904 The code now assures that all data is read from the fd and then
7905 continues packet processing. This was a bug fix since the code
7906 used to drop some data in some circumstances.
7908 * Added new function into lib/silcclient/client.[ch]:
7909 silc_client_start_key_exchange to start key exchange after
7910 connection has been established to server. The code internally
7911 now uses this funtion but its main purpose was to provide it
7912 for applications that perform their own connecting. After
7913 application has created a connection it merely calls this
7914 function to start the key exchange between client and server.
7915 The library takes care of everything else after that.
7917 Updated also lib/silcclient/README to explain the usage of
7920 * Do not send to application information that connection has
7921 been established. Application gets notified it by connect
7924 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7926 * Applied cras's patch to add silc_schedule_one function. The
7927 function runs scheduler once and returns.
7929 * Fixed the scheduler after cras messed it up. The timeout
7930 handling works now as it's supposed to work.
7932 * Added into lib/silccore/ silcnotify.h to include notify
7933 message types support. Changed silc_server_send_notify*
7934 functions, in server.[ch], to support those new notify types.
7935 Added the support for the notify types into client library,
7936 as well. Added new notify client operation into ops.h in
7939 * Changed silc_server_packet_send_to_channel to send normal
7940 packets instead of just channel message packets. The function
7941 is now used to send the notify packets to channels. It is not
7942 used to send channel message packets anymore, as server never
7945 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7946 va_arg()s as it seems to require it nowadays. I guess, if SILC
7947 is compiled with older va_arg() the new code should work anyway.
7949 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7951 * Splitted core library. Core library (lib/silccore) includes
7952 now only SILC protocol specific core (and common) components.
7953 Created new utility library (lib/silcutil) that includes more
7954 generic purpose stuff. The stuff for util library was taken
7955 from the old core library. This was minor and easy split.
7957 * Created SILC Client Library (lib/silcclient) that includes
7958 implementation of the SILC client without user interface. This
7959 was major move from silc/ directory. The code has been changed
7960 so that it is transparent towards the user interface. The
7961 silc/ directory includes now the same user interface as before
7962 and it uses the new client library. Read lib/silcclient/README.
7963 Basicly, the client library performs everything else related
7964 to SILC except user interface handling. Also, configuration
7965 files are considered to be part of user interface and library
7966 does not handle them.
7968 This change also changed a lot of structures, function naming etc.
7969 Most important change was that SilcClientWindow object was
7970 renamed to SilcClientConnection in the client library. Created
7971 also new file lib/silcclient/ops.h. Also added new files
7972 silc/local_command.[ch] and silc/client_ops.[ch].
7974 All these changes were made to make it easier for user interface
7975 designers to create what ever user interface for the SILC client
7978 It is also expected that the server will be moved to lib
7979 directory as well and SILC Server Library will be created;
7980 sometimes in the future.
7982 * Removed Local commands from lib/silccore/silccommand.h as
7983 they are application specific and new client library does not
7984 handle any of those anymore.
7986 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7987 old client implementation in silc/.
7989 * Added support for callback functions in SILC_LOG_* macros.
7990 Application can now set its own callbacks that will be called
7991 instead of using the default functions that will always print
7992 the debug messages to stderr (or stdout). Also, debugging can
7993 now be disabled by setting silc_debug to FALSE and re-enabled by
7994 setting it to TRUE. Note, that logging will still work even
7995 if debugging is disabled.
7997 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7998 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7999 silc_log_reset_debug_callbacks.
8001 * To enable debugging in silc client one must give now -d
8002 option on command line.
8004 * Changed silc_schedule_init to automatically allocate task queues
8005 if they are not allocated before calling it.
8007 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8009 * Added GMP 3.1 into math library.
8011 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8014 a channel in SILC network. The packet is used by servers and
8015 routers to notify other routers that user has left a channel.
8016 This little feature was missing until now. Added the feature
8017 to protocol specification as well.
8019 Added functions: silc_server_send_remove_channel_user and
8020 silc_server_remove_channel_user into server.[ch].
8022 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8023 lib/silccore/silcpacket.h. However, they are not implemented
8026 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Fixed joining to a channel and sending channel messages
8029 between server and router. The channel message sending should
8030 now work inside a cell.
8032 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8034 * Fixed the private message sending between server and router.
8035 The private message sending should now work inside a cell.
8037 * Added silc_server_replace_id into server.[ch] to replace
8038 existing ID in the SILC network.
8040 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8041 and silc_idlist_replace_server_id into idlist.[ch] in server.
8043 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8045 * Fixed the server to server connections. Server can again now
8046 connect to router. Router to router connections probably does
8049 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * Added dynamic protocol registering support. Now protocols can
8052 registered and unregistered on the fly. Patch by cras.
8054 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8056 * Added lib/contrib directory to hold routines that some platforms
8057 don't have but are needed by SILC.
8059 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8060 into lin/contrib to provide getopt() and getopt_long() for
8061 those who don't have it.
8063 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8065 * Added AWAY command to client. When away message is set and
8066 client receives a private message packet the client automatically
8067 replies to the sender with the away message.
8069 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8070 bug seemed to be the cause of recent problems when compiling
8073 * Added version detection support to SKE protocol specification
8074 and added the new changes to the SKE implementation as well.
8075 There were other minor changes in the SKE protocol as well.
8077 Many changes in lib/silcske/silcske.[ch] and in
8078 lib/silcske/payload.[ch].
8080 * Added ^U functionality, clear input line. Patch from cras.
8082 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8084 * Mainly small bugfixes on core library. Fixed some debugging
8085 logging and buffer overflow in silclog.c.
8087 * Updated config.sub and config.guess on the distribution tree.
8089 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8091 * Added command lagging support in server. Client may execute
8092 commands now only once in two seconds.
8094 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Optimized packet reception. MAC computation and checking is now
8097 also more optimized. A lot previously duplicated code is now
8098 used as generic by both client and server.
8100 * Fixed key pair generation in clientutil.c
8102 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8104 * Added into lib/silccore/silcbufutil.[ch] new function;
8105 silc_buffer_realloc.
8107 * Moved generic packet sending/encryption functions to
8108 lib/silccore/silcpacket.[ch] from client and server. Some
8109 rewriting of the functions.
8111 * Moved all generic packet reception/decryption functions to
8112 lib/silccore/silcpacket.[ch] from client and server. The
8113 packet processing is now much cleaner in both client and server.
8114 These were major changes in both client and server.
8116 * Created many common functions in server to do packet sending.
8117 Previously code were duplicated a lot, this has been removed
8120 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8122 * Rewrote major parts of the ID cache system. Don't know
8123 whether it is better now or not but at least the API is more
8126 * Major rewrite on ID cache stuff on client because of the ID
8127 cache API changes. Added idlist.c to client.
8129 * Also major rewrite on ID cache stuff on server as well.
8130 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8131 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8132 in hand, instead they are all put into the ID cache system now.
8133 All server_idlist_* routines uses ID cache now instead of
8134 traversing its own lists (those lists does not exist anymore).
8135 SilcIDList though still exists. Also, SilcXXXEntry's are
8138 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Finally made the SKE implementation compliant to the protocol
8141 specification. All mp integers are now binary encoded as
8142 opposed being HEX encoded.
8144 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8147 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8148 functions: silc_[encode/decode]_pem. Also added function
8149 silc_encode_pem_file to PEM encode with newlines ('\n') for
8152 * SILC public keys are now encoded either PEM or binary. Same
8153 option is for private keys as well. By default private keys
8154 are binary encoded and public keys PEM encoded. Silly HEX
8155 encoding were removed.
8157 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8158 function to create fingerprints.
8160 * Fixed a bug in SHA1; does not change the original data anymore.
8162 * Partly implemented INFO command on client and server side.
8163 Fixed CLEAR command. Changes to SERVER command; show current
8164 server(s) when giving command without arguments. Added
8165 VERSION command to client.
8167 * Added check to server that unregistered connections cannot
8168 execute commands (unless it is specificly allowed).
8170 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Fixed screen refresh.
8174 * Fixed channel joining bug from client. On some circumstances
8175 client tried to join to a channel it had already joined.
8177 * Added public key verification process into client's protocol.c.
8178 The client now verifies the public key from user and saves
8179 it into ~./silc/serverkeys/ directory.
8181 Added into: clientutil.[ch]: silc_client_verify_server_key.
8183 * Changed SKE protocol's silc_ske_initiator_finish function
8184 to accept callback function that verifies the received public
8185 key. Removed old silc_ske_verify_public_key function.
8187 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8189 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8190 silc_pkcs_private_key[_data]_set.
8192 * Made the password and public authentication more cleaner in
8193 server's protocol.c.
8195 * Removed historic and obsolete protocol `channel_auth' from
8196 both client and server.
8198 * Removed wrong way of sending command status messages from
8199 server to client in server's command.c. The old way violated
8200 protocol specification.
8202 Changes to silccore/silccommand.[ch]: removed
8203 silc_command_encode_status_payload -> not needed anymore,
8204 changed silc_command_encode_payload_va to accept extra
8205 argument on variable argument list. The argument type must
8206 now be provided to the function. Also, added new function:
8207 silc_command_encode_reply_payload_va which is same as
8208 normal command_encode_payload_va except command status type
8209 is provided as extra argument.
8211 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Added ~./silc directory handling. The directory includes the
8214 public and private keys for the client.
8216 Added silc_client_check_silc_dir, silc_client_create_identifier
8217 and silc_client_load_keys.
8219 * Implemented SILC protocol compliant public key. Added public
8220 and private key saving to and loading from files.
8222 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8223 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8224 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8225 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8226 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8228 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8229 silc_pkcs_load_[public/private]_key.
8231 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Added silc_server_get_route (route.[ch]) to get connection
8234 data for the fastest route for given ID.
8236 * Implemented INVITE command on client and server. The command
8237 were re-defined in the SILC Protocol Specification and the
8238 implementation now complies with the specification.
8240 * Implemented PING command on client and server.
8242 * Implemented NAMES command on client and server. The server side
8243 supports currently only normal server not router server yet.
8244 Some changes to NAMES definition in SILC protocol specification.
8246 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * Implemented LEAVE command on client and server.
8250 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8251 again. This change was made to the protocol as well. Server
8252 should not violate the protocol specification anymore.
8254 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8256 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8257 was tested. SOCKS4 was not but should work anyway.
